Europe's oldest living person has survived COVID-19 after testing positive just weeks before her 117th birthday. Sister André, a French nun who was born in 1904, tested positive in the retirement home where she lives in Toulon, southern France, on January 16, according to the home’s communications director, David Tavella. André, who was born Lucille Randon, showed no symptoms from the virus and didn’t even know she was infected until she received her positive test. Despite no visitors being allowed because of strict COVID protocols, André is preparing to celebrate her 117th birthday today, Thursday 11th February. She will reportedly receive video messages from her family and the local mayor, as well as taking part in a video Mass, Tavella said. André's birthday meal will feature her favorites: foie gras, baked Alaska and a glass of red wine, Tavella added. Remarkably, André has lived through two world wars, as well as the 1918 Spanish Flu pandemic that infected around 500 million people. While Andre is the oldest living person in France today, she’s not the oldest in the world. That crown is held by Kane Tanaka, a Japanese woman who was born in 1903, according to the Gerontology Research Group (GRG). * Image credit Gérard Julien/AFP/Getty Images
The US is entering its annual cold and flu season, but this year there’s the added danger of Covid-19 to contend with. Healthcare providers often struggle to meet the needs of their patients at this time of year, mainly because of increased footfall at their facilities. Add to this the strict social distancing guidelines that are in place across the world and the difficulty of the situation becomes clear. The good news is that more and more care providers are turning to telehealth solutions to help alleviate the flu season rush, as well as adhere to social distancing rules. With telehealth, doctors and physicians can carry out consultations with patients without either having to travel. When diagnosing a patient with the flu, physicians look for the two most common symptoms: a cough and fever. At the height of the flu season, almost every patient presenting with these symptoms will have the flu, which often means an in-person consultation is not necessary in the first instance. Care providers can quickly assess a patient’s symptoms via a virtual consultation and arrange to have a prescription sent to them, saving time and money. While every patient’s case is unique, the ability of telehealth to enable physicians to carry out initial consultations for individuals with flu-like symptoms remotely means the facility’s resources are not impacted. This frees up vital appointment slots for those who need them most and reduces wait times, all the while eliminating the chances of someone contracting Covid-19 or spreading flu while out of their house.

A new 90-minute test that can distinguish if someone has COVID-19 or another seasonal illness will be highly beneficial come the flu season (December to March) in the UK, the government there has said. The “on-the-spot” swab and DNA tests can detect coronavirus and flu. They will be rolled out in hospitals and care homes across the UK starting next week. At present, a third of COVID-19 tests in the UK take at least 24 hours to process. The UK Government has said that almost half a million of the new rapid tests, called LamPORE, will be available from next week in hospitals and care homes. The investment will help the UK Government work towards hitting its target of testing all care home staff and residents — a move that’s designed to identify so-called ‘silent spreaders’ individuals who are infected but asymptomatic. In addition, thousands of DNA test machines that can analyse nose swabs will be deployed to UK NHS hospitals from September, following successful rollouts across eight London hospitals. The c. 5,000 machines will provide around 5.8m test over the coming months. While the accuracy of the new swab and DNA tests has not yet been determined, Sir John Bell, Regius Professor of Medicine at Oxford University, said they are on a par with current lab-based tests.
With many countries now seemingly in control of the COVID-19 pandemic, attention is turning to a potential ‘second wave’ of the virus. But what does this actually mean? The Spanish Flu pandemic that began in early March 1918 lasted for around two years. But it was the second wave of the virus during three especially cruel months in the fall of 1918 that proved to be the deadliest. It raises questions about whether there will be a second wave of COVID-19. Now the easiest way to picture a second wave is to think of waves on the sea. The total number of infections goes up and then down, until the next wave comes along and the process begins all over again. To say that one wave has ended, the total number of infections needs to fall substantially. If we were then to see a significant rise once more, it would be safe to say that we are experiencing a so-called second wave. Health officials in South Korea believe the country is now experiencing a second wave of COVID-19 infections. Despite being one of the success stories of the pandemic, officials are now bracing for potential restrictions for several more months. While global lockdowns have had a profound impact on economies and people’s lives, lifting them too much and too early could lead to a second wave of COVID-19. That’s why any easing will come in stages and contact tracing and wearing face masks could be the new norm for a while. Hopefully, with effective social distancing measures and frequent handwashing, a second COVID-19 wave can be averted. However, what actually happens remains to be seen.

Research shows warmer temperatures do slow COVID-19 transmission (but not by much) Warmer temperatures have long been associated with reduced transmission rates of some respiratory viruses. It’s one of the reasons why flu tends to have a much larger impact during winter months. Therefore, it stands to reason that the spread of SARS-CoV-2 could also be slowed or even halted as countries start to experience warmer temperatures. Now, research seems to have confirmed what many people have thought. For the study, researchers from the Mount Auburn Hospital in Cambridge, Massachusetts looked at the effect of temperature, precipitation, and UV index on COVID-19 case rates in the United States from January 22, 2020 through April 3, 2020. They found the rate of COVID-19 incidence does decrease as temperatures get warmer, up until 52 degrees F. After that, virus transmission does not decrease significantly. Furthermore, while the overall impact remains modest, a higher UV index also assists in slowing the growth rate of new cases. Precipitation was not found to have any impact on the spread of the virus. The findings will comes as welcome news as many states in America see warmer weather easing in. However, the Centers for Disease Control and Prevention has warned that the COVID-19 pandemic could worsen again in the fall and winter as temperatures drop.

The widespread panic and uncertainty being caused by the ongoing COVID-19 pandemic means sleep isn’t coming easy for many people right now. But good quality sleep is the bedrock of our lives, consuming about a third of our total time on this planet and dramatically influencing the other two-thirds. That’s why it’s so important that we all get enough good quality sleep on a regular basis. With that in mind, here are five tangible tips to promote better sleep at this difficult time: 1. Get into a routine By getting in sync with your body’s natural sleep-wake cycle, or circadian rhythm, you can significantly boost your chances of getting a good night’s sleep. If you get into a routine of sleeping and waking at the same times each day, you’ll feel more refreshed and energized than if you follow random patterns. 2. Exercise more In addition to the physical and mental health benefits, regular exercise also helps you sleep better. And while cardiovascular exercise, strength training and yoga are all great for helping you sleep – especially if you do them during the day and not just before bed. 3. Watch your diet For the best sleep, try and eat a balanced diet that contains vegetables, fresh fruits, whole grains, and low-fat proteins that are rich in B vitamins - like fish, poultry, meat, eggs, and dairy. 4. Consume less alcohol While some people rely on alcohol to help them fall asleep, studies show that alcohol does not improve sleep. In fact, it reduces rapid eye movement (REM) sleep, which is thought to be the most restorative kind. 5. Limit gadget use at night Blue light from TVs, smartphones, tablets and other gadgets plays havoc with your circadian rhythm and, as a result, the release of the sleep-inducing hormone melatonin is suppressed. For the best night’s sleep, limit your use of gadgets and other visual devices to around one to two hours before bed.
It’s impossible to turn on the news at the moment and not be greeted with updates about the coronavirus disease, COVID-19. The problem, however, with so much news coverage is that it can be difficult to discern which pieces of information are true and which are simply myths. To help provide some clarity, we have compiled this list of coronavirus myths: Myth 1. Children cannot catch the new coronavirus (SARS-CoV-2) While the majority of coronavirus cases have been in adults, people of any age can become infected with SARS-CoV-2. What is true is that adults with several pre-existing health conditions are more likely to become severely ill. Myth 2. COVID-19 is just like the flu While COVID-19 causes many symptoms that could be described as ‘flu-like’ and both illnesses can lead to pneumonia, the overall profile of COVID-19 is more serious than ordinary flu. While the actual mortality rate of COVID-19 remains unclear, it is expected to be many times higher than that of seasonal flu. Myth 3. Antibiotics kill coronavirus COVID-19 is caused by SARS-CoV-2, a virus. Antibiotics only kill bacteria, so they are all but useless against the new coronavirus. Myth 4. Thermal scanners can diagnose coronavirus The only thing that thermal scanners can detect is an elevated body temperature (a fever). While this is one of the symptoms of COVID-19, it cannot be used to diagnose the disease alone. Myth 5. Face masks protect against coronavirus Wearing a face mask is not guaranteed to protect you from SARS-CoV-2 – especially if the face mask is ill-fitting. Where face masks can make a real difference is when they are worn by people with the virus, as they can help prevent others from becoming infected.

A new study has revealed five bad health habits which, if avoided, could help you live significantly longer. While the habits themselves are nothing we haven’t heard before, the findings of the study are important as they highlight just how much of an impact the five factors can have on lifespan. So if you want to live years longer, avoid these five behaviours: smoking, not exercising, being overweight, drinking too much alcohol and eating an unhealthy diet. Specifically, the study found that women aged 50 who avoided all five risk factors lived 14 years longer than women who did not. Among men, the difference in lifespan was 12 years. Publishing the study findings in the BMJ, senior author Dr. Frank Hu, who chairs the department of nutrition at Harvard T.H. Chan School of Public Health, said: “We found that following a healthy lifestyle can substantially extend the years a person lives disease-free.” Importantly, the results held true even after adjusting the data for age, ethnicity, family medical history and other potentially influential factors – emphasising that everyone stands to benefit from avoiding these five unhealthy habits. Finally, the research also revealed that the five habits had a positive impact for people diagnosed with a disease during the study period. For example, individuals who developed cancer lived an additional 23 years if they adopted four of the five healthy practices. In contrast, among those who didn't change, half only survived an additional 11 years. The same patterns were witnessed for both heart disease and diabetes.
People with type-2 diabetes get no benefit from taking omega-3 fish oil supplements, a new study has found. According to researchers from the University of East Anglia, while omega-3 supplements are not harmful for people with type-2 diabetes (this has been a concern previously), they don’t provide any benefit either. This contradicts a common belief that omega-3 can protect against diabetes and even reverse the condition. The study, which involved 58,000 participants, found that people who consumed more omega-3 had the same risk of developing diabetes as individuals who did not. Furthermore, taking omega-3 fish oil did not influence levels of blood glucose, insulin and glycated haemoglobin - all measures of how the body handles sugar. ‘Better to eat fish’ Douglas Twenefour, deputy head of care at Diabetes UK, said: “Eating a healthy, varied diet is incredibly important, and we know that certain foods - including fruits, vegetables, wholegrains, yoghurt and cheese - can help to lower your risk of type 2 diabetes. “While omega-3 fatty acids are crucial for our overall health, it's generally better for people with type 2 diabetes to get their intake by eating at least two portions of oily fish a week, than by taking supplements." The advice from Dr Lee Hooper, who led the research, is to forego the expensive omega-3 supplements and instead buy oily fish and/or spend your money on physical activity, which will have more of a positive impact when it comes to type-2 diabetes.
If you’re looking to lose some weight, eating earlier in the day and intermittently fasting could help, new research suggests. According to a paper published in the journal Obesity, the timing of meals and intermittent fasting influences metabolism, which can have an impact on weight loss. Researchers discovered this following a trial involving 11 men and women, all of who were in good health, aged between 25 and 45 years and carrying some excess weight. The trial participants were split into two groups: one who ate breakfast at 08:00 and then ate their last meal of the day at 14:00, and another who ate breakfast at 08:00 and had their last meal of the day at 20:00. Both groups ate the same meals each day. At the end of the trial, participants underwent a battery of tests in a respiratory chamber to assess their metabolism. The number of calories, fat, carbohydrates and proteins burned were all measured. It was revealed that the participants who ate their last meal of the day at 14:00 and, therefore, fasted longer overnight, burned more fat than the other group. They also had lower levels of the hunger hormone ghrelin. “Eating in sync with circadian rhythms by eating early in the daytime appears to reduce body weight and improve metabolic health,” the authors of the paper wrote.
Charcoal-based toothpastes - which claim to help whiten teeth - could actually increase the risk of tooth decay and staining, a review published in the British Dental Journal has found. According to the review, charcoal-based toothpastes often contain little or no fluoride to help protect teeth and the claims they make about whitening are not supported by any evidence. Furthermore, excessive brushing with them can actually do more harm than good because they are often more abrasive than regular toothpastes and can cause damage to tooth enamel and gums. The authors of the paper say people should stick to brushing with a regular fluoride toothpaste and consult their dentist about teeth bleaching/whitening. Speaking about the review, Prof Damien Walmsley, from the British Dental Association, said: “Charcoal-based toothpastes offer no silver bullets for anyone seeking a perfect smile, and come with real risks attached. “So don't believe the hype. Anyone concerned about staining or discoloured teeth that can't be shifted by a change in diet, or improvements to their oral hygiene, should see their dentist.” The bottom line, according to study co-author Dr Joseph Greenwall-Cohen, from the University of Manchester Dental School, is that charcoal-based toothpastes do not provide “a low cost, quick-fix, tooth-whitening option.”
Our daily diets are bigger killers than smoking and account for one in five deaths around the world. In other words, the food you eat could be sending you to an early grave. But which diets are the worst? Well, according to an influential study in The Lancet, salt – whether it be in bread, processed meals or soy sauce – shortens the most lives. The Global Burden of Disease Study used estimates of different countries’ eating habits to determine which diets were shortening the most lives. Here are the three most dangerous diets: Too much salt - three million deaths Too few whole grains - three million deaths Too little fruit - two million deaths Low levels of seeds, nuts, vegetables, fibre and omega-3 from seafood were the other major killers. Speaking to the BBC, Prof Christopher Murray, the director of the Institute for Health Metrics and Evaluation at the University of Washington, said: “We find that diet is one of the dominant drivers of health around the world, it's really quite profound.” Salt is such a big problem because it significantly increases a person’s blood pressure, which in turn increases their chances of heart attacks and strokes. Around 10 million out of the 11 million diet-related deaths were because of cardiovascular disease, highlighting why diets containing too much salt are such a problem.
The health benefits of eating fiber have long been hailed, but how much fiber should we all be eating to prevent chronic disease and premature death? A new study reveals just that… Commissioned by the World Health Organization (WHO), the research is the culmination of a meta-analysis of observational studies and clinical trials that took place over almost 40 years. The results appear in the journal The Lancet. One of the objectives of the research was to help in the development of new guidelines for dietary fiber consumption, as well as discover which carbs protect us the most against noncommunicable diseases. So how much fiber should we be eating? Well, the research found that a daily intake of 25–29 grams of fiber is ideal. People who consumed this amount of fiber each day were 15–30 percent less likely to die prematurely from any cause and had a 16–24 percent lower incidence of stroke, coronary heart disease, type 2 diabetes, and colon cancer. The researchers also say that consuming more than 29 grams of fiber per day could lead to even more health benefits. Speaking about the findings of the study, Professor Jim Mann, of the University of Otago, in New Zealand, said: “The health benefits of fiber are supported by over 100 years of research into its chemistry, physical properties, physiology, and effects on metabolism. “Fiber-rich whole foods that require chewing and retain much of their structure in the gut increase satiety and help weight control and can favorably influence lipid and glucose levels. “The breakdown of fiber in the large bowel by the resident bacteria has additional wide-ranging effects including protection from colorectal cancer.” Fiber-rich foods include vegetables, whole grains, fruit, and pulses, such as beans, peas, lentils, and chickpeas. Are you consuming enough fiber?
AVIS D’EXPERT - Une concentration en potassium dans le sang supérieure à la normale peut notamment être le signe d’une maladie rénale. Les médecins prescrivent souvent des dosages des principaux électrolytes (éléments chimiques porteurs de charge électrique) du plasma (sodium, potassium, chlore,bicarbonate) chez les malades hypertendus ou atteints de maladies cardiaques ou rénales. Le plasma est le liquide qui transporte les différentes cellules du sang. Connaître les concentrations dans le plasma de ces substances est essentiel parce qu'elles jouent un rôle majeur dans les transferts d'eau entre les différents compartiments hydriques, la régulation du pH (index de l'acidité) du plasma et la transmission de l'influx nerveux. Quelles sont les causes possibles d’un excès de potassium? Comment celui-ci se traite-t-il? Le Pr Raymond Ardaillou, néphrologue et secrétaire perpétuel de l’Académie de médecine fait le point. Potassium: quelle concentration normale? La concentration en potassium dans le plasma sanguin est normalement comprise entre 3,6 et 5 mmol/l (130 à 200 mg/l). La répartition du potassium dans l'organisme est très inégalitaire puisque sa concentration dans les cellules varie de 90 à 150 mmol/l. L'alimentation apporte environ chez un adulte 60 à 120 mmol de potassium par jour. Les aliments les plus riches en potassium sont les fruits, les légumes et le chocolat. Le potassium ingéré est en quasi-totalité absorbé dans le tube digestif et se retrouve dans les urines en quantité équivalente à celle absorbée dans l'intestin. Le rôle physiologique principal du potassium, porteur d'une charge positive, est de générer le potentiel de membrane qui est la différence de charge électrique de part et d'autre de la membrane cellulaire, l'intérieur de la cellule étant électronégatif par rapport à l'extérieur. La sévérité de l'hyperkaliémie (augmentation de la concentration de potassium dans le plasma) provient de la perturbation qu'elle provoque, du potentiel de membrane dans les cellules cardiaques et des troubles du rythme qui s'ensuivent. Les causes possibles d’un excès de potassium L'hyperkaliémie provient soit d'un défaut d'excrétion rénale du potassium, soit d'un passage accru du potassium cellulaire dans le compartiment extra-cellulaire. Les hyperkaliémies d'origine rénale surviennent en cas d'insuffisance rénale ou, sur reins sains, si la sécrétion d'aldostérone, une hormone qui contrôle le transport du sodium et du potassium dans la partie distale du néphron (unité structurale et fonctionnelle du rein qui possède environ 1.000.000 de néphrons), est insuffisante.
Par Martine Lochouarn Publié le 17/06/2018 à 06:00 INFOGRAPHIE - Un diagnostic précoce de ce cancer permettrait d’améliorer la prise en charge. Au cinquième rang mondial par sa fréquence, le cancer de l’estomac figure en troisième place par le nombre de morts, près de 9 % de tous les décès par cancer. Son incidence varie selon les régions du globe, les ethnies et le niveau de développement. L’Asie de l’Est, Japon, Corée et Chine surtout, est fortement touchée, mais aussi l’Amérique du Sud. «Intermédiaire en Europe de l’Est, son incidence est plus faible en Europe de l’Ouest, à l’exception du Portugal, fortement touché», explique le Pr Tamara Matysiak-Budnik, gastro-entérologue et cancérologue (CHU Nantes). En France, de 6000 à 7000 nouveaux cas sont diagnostiqués chaque année, pour 4500 décès. C’est un cancer du sujet âgé, de pronostic médiocre. En quelques décennies, les progrès de l’hygiène alimentaire ont beaucoup réduit son incidence, qui est aujourd’hui assez stable. «L’association démontrée entre infection par H.pylori et cancer gastrique est aussi forte que celle entre tabac et cancer du poumon.» Pr Tamara Matysiak-Budnik, gastro-entérologue et cancérologue (CHU Nantes) La forme la plus fréquente, qui touche le corps et la partie basse de l’estomac, diminue encore peu à peu, mais les cancers de la jonction estomac-oesophage (cardia) plus rares, augmentent avec l’épidémie d’obésité qui favorise le reflux gastro-œsophagien. Moins de 5 % des cancers sont d’origine génétique. Il s’agit souvent de cancers «diffus», infiltrant l’estomac, de très mauvais pronostic, qui touchent des sujets jeunes. Mais le premier facteur de risque de cancer de l’estomac, c’est l’infection par Helicobacter pylori, responsable de près de 90 % des cas. Cette bactérie acquise dans l’enfance colonise la muqueuse gastrique, le plus souvent sans symptôme. «L’association démontrée entre infection par H. pylori et cancer gastrique est aussi forte que celle entre tabac et cancer du poumon», explique la gastro-entérologue. En France, de 20 à 30 % des individus sont infectés, mais 80 % le sont en Afrique et 10 % dans les pays nordiques. Parmi les personnes infectées, de 2 à 20 % auront un ulcère, et parmi elles 1 % aura un cancer gastrique. «Ce processus complexe de carcinogenèse s’étend sur des décennies et passe par une cascade d’étapes, dont la première, la gastrite superficielle, ne survient pas sans infection par H. pylori, ce qui ne signifie pas que cette infection est suffisante», explique le Pr Matysiak-Budnik. L’excès de sel, de viande rouge, d’aliments fumés, le tabac favorisent aussi ce processus, les fruits et légumes ayant un effet protecteur. Les antibiotiques pour éradiquer la bactérie «L’éradication par antibiotiques de l’infection à H. pylori guérit et fait régresser les gastrites superficielles et la plupart des gastrites atrophiques, prévenant ainsi le cancer de l’estomac.» Comme l’incidence de ce cancer est faible en France, un dépistage sur toute la population ne paraît pas adapté. Mais il existe au Japon, et la Slovénie l’envisage. En revanche, la recherche de H. pylori et son éradication sont indispensables dans les formes héréditaires, chez les parents au premier degré de personnes ayant un cancer gastrique, chez les personnes ayant un ulcère, une gastrique atrophique, précancéreuse, ou ayant subi une ablation partielle de l’estomac pour cancer, et chez celles traitées au long cours par certains médicaments anti-acide, les IPP (inhibiteurs de la pompe à protons). La lésion peut être retirée par endoscopie Si le cancer gastrique a un pronostic médiocre, c’est d’abord à cause de son diagnostic tardif, les cancers précoces ne donnant pas de symptômes. Parfois, une lésion précoce est découverte par des signes très généraux comme une anémie. «Mais le plus souvent ils sont détectés à un stade évolué, parce que surviennent une hémorragie digestive, des douleurs qui ressemblent à un ulcère, un amaigrissement, des difficultés d’alimentation… C’est l’examen endoscopique et la biopsie des lésions qui confirment ce diagnostic, explique le Pr Thomas Aparicio, gastro-entérologue et cancérologue (hôpital Saint-Louis, Paris). Si la lésion est petite et superficielle, elle est parfois enlevée par endoscopie dans des centres très expérimentés. Mais la laparoscopie est moins utilisée que dans le cancer du côlon, et l’ablation chirurgicale se fait le plus souvent en ouvrant l’abdomen.» Le principal progrès de ces quinze dernières années dans l’amélioration de la survie, c’est la chimiothérapie périopératoire, avec en général deux mois de chimiothérapie préopératoire pour réduire la tumeur et éliminer les micrométastases, et deux mois de chimiothérapie postopératoire. Les 30 % de cancers métastatiques d’emblée ne sont pas opérés. Comme pour d’autres tumeurs, ces formes métastatiques commencent à bénéficier des avancées des thérapies ciblées et de l’immunothérapie. Mais, globalement, les progrès sont modestes et les essais souvent décevants. «Notre arme principale reste la détection, le plus précoce possible, qui a un peu progressé puisqu’on identifie 10 % de cancers superficiels précoces, contre 4 % il y a dix ans», insiste le Pr Matysiak-Budnik. De nouveaux tests en cours d’évaluation pourraient aider à améliorer ce dépistage…
Babies who are fed solid food in addition to breast milk from the age of three months sleep better than those who are solely breastfed, a new study has revealed. Publishing their findings in JAMA Pediatrics, the authors of the study noted the following: “The World Health Organisation recommends exclusive breastfeeding for 6 months. However, 75% of British mothers introduce solids before 5 months and 26% report infant waking at night as influencing this decision.” Experts say women should still heed WHO’s advice, but that the guidelines are currently under review. For the study, the researchers from King's College London, and St George's, University of London, split 1,303 three-month-old infant into two groups: one that was solely breastfed and one that also had solid foods incorporated from the age of three months. The babies’ parents were then surveyed to see if the addition of solid foods had made a difference to the sleep patterns of the infants and the mothers’ quality of life. The parents of the babies who were given solid foods from three months reported that their children slept longer, woke less frequently and had far fewer serious sleep problems. Prof Gideon Lack from King's College, London, said: "The results of this research support the widely held parental view that early introduction of solids improves sleep. "While the official guidance is that starting solid foods won't make babies more likely to sleep through the night, this study suggests that this advice needs to be re-examined in light of the evidence we have gathered."

INFOGRAPHIE - À partir de 30 ans, la plupart des gens se sentent moins âgés que leur véritable nombre d’années. Un écart de perception qui peut aller jusqu’à une décennie, et ne diminue qu’après 80 ans. On connaissait les températures ressenties, voilà maintenant l’âge ressenti, celui que l’on a l’impression d’avoir. L’idée n’est pas nouvelle mais les chercheurs s’intéressent de plus en plus à cet âge subjectif, car il serait un bon indice de longévité réussie. Vous n’avez pas l’impression d’avoir votre âge? Vous n’êtes pas seuls. C’est même le cas de la majorité des gens de votre âge. Mais à partir de quel âge se sent-on vieux? La réponse dépend de l’âge… que l’on a! Des psychologues de l’université du Michigan en collaboration avec des chercheurs de l’université du Minnesota et de Stanford (Californie) ont en effet posé la question à plus de 500.000 personnes âgées de 10 à 89 ans, via Internet, entre 2006 et 2015. Les réponses sont fluctuantes en fonction de l’âge de la personne interrogée. Celles qui ont 20 ans placent la barre de la vieillesse autour de 60 ans, mais celles qui en ont 60 la repoussent à 70 ans environ. Autre question double posée aux internautes, quel âge avez-vous et quel âge avez-vous l’impression d’avoir? Jusqu’à 30 ans environ, l’âge perçu est assez fidèle aux nombres de bougies sur votre gâteau d’anniversaire, même si un nombre non négligeable d’individus se sentent un peu plus vieux que leur âge (environ 3 ans de plus à 20 ans pour la moitié des gens). En revanche, à partir de 30 ans la majorité des répondants commencent à avoir une perception ralentie de leur âge. Et passé 50 ans, la plupart des gens ont l’impression d’avoir dix ans de moins. Cela reste vrai jusqu’aux environs de 80 ans, âge ou la sensation de décalage se réduit enfin. Ces résultats publiés dans la revue Frontiers in Psychology sont finalement assez proches de ceux obtenus il y a une douzaine d’années sur un échantillon de près de 1.500 Danois par David Rubin de l’université Duke, en Caroline du Nord et Dorthe Berntsen de l’université d’Arhus au Danemark. Sauf qu’au Danemark, plus on vieillissait et plus l’écart se creusait entre l’âge ressenti et l’âge réel. Ainsi, le décalage perçu par la majorité des répondants était-il de huit ans de moins à 40 ans, douze de moins à 60 ans, ou encore seize ans de moins à 80 ans (voir tableau). Les auteurs remarquaient cependant que cet écart restait constant proportionnellement à l’âge ; soit une réduction de 20 % de l’âge réel, à partir de l’âge de 40 ans.
Some of us turn to food for comfort when we are feeling emotional or stressed. Likewise, some of us cut back on food when we are feeling upset. But they are habits that could be influencing our children too. That’s because new research by University College London has found that children who eat more or less when stressed or upset have learnt the behaviour rather than inherited it, suggesting home environments are the primary cause of emotional eating. Parental acts such as giving children their favourite food when they are feeling upset have been highlighted as potential reasons for the habits forming. But UK-based eating disorder charity Beat says parents shouldn’t be blamed for their children’s eating issues. "Eating disorders are complex mental illnesses and never have one sole cause," the charity said. The study, which was published in the journal Pediatric Obesity, analysed 398 four-year-old British twins. Half came from families with obese parents and half from parents with a healthy weight. The parents were asked questions about their children’s eating habits, including their tendencies to emotionally eat. The researchers compared the questionnaire data relating to eating disorders between identical and non-identical twins and found very little difference between the two, which suggests environment plays a bigger role than genes.
The modern, germ-free lifestyles many children lead could be responsible for the most common type of cancer in children - acute lymphoblastic leukaemia - according to one of the UK’s most well-respected scientists. Professor Mel Greaves, from the Institute of Cancer Research, has been studying for 30 years how the immune system can become cancerous if it is not exposed to enough bugs early in life. Acute lymphoblastic leukaemia affects one in 2,000 children and is more common in advanced, affluent societies, suggesting cleaner modern lifestyles could play a defining role. Prof Greaves says the disease happens in three stages: a genetic mutation inside the womb, a lack of exposure to microbes in early life and an immune malfunction and leukaemia in childhood. He believes that it could be possible to prevent the condition. Prof Greaves said: "The research strongly suggests that acute lymphoblastic leukaemia has a clear biological cause and is triggered by a variety of infections in predisposed children whose immune systems have not been properly primed." Unfortunately, preventing the disease isn’t as simple as exposing children to dirt. They need, according to Prof Greaves, contact with beneficial bacteria. The best way to do this is to give them a safe cocktail of bacteria, such as in a yoghurt drink, that will help boost their immune system.

Cranberry juice has long been used by people to provide relief from and even treat urine infections. But new draft guidelines from the National Institute for Health and Care Excellence (NICE) say there is not enough good evidence, despite people’s experiences, to recommend it as a treatment. Even though some studies have concluded that cranberry juice may be beneficial for people with urine infections, NICE says people should drink plenty of water or fluids and take painkillers instead. Urinary tract infections (UTIs) are caused by bacteria, which is why some people may be prescribed antibiotics to treat them, but these drugs are not always necessary. NICE says that when antibiotics are required, the shortest course possible should be prescribed to reduce the risk of antimicrobial resistance. Prof Mark Baker, director for the centre of guidelines at NICE, said: "We recognise that the majority of UTIs will require antibiotic treatment, but we need to be smarter with our use of these medicines. "Our new guidance will help healthcare professionals to optimise their use of antibiotics. "This will help to protect these vital medicines and ensure that no one experiences side effects from a treatment they do not need."
Older individuals who do lots of exercise can prevent their immune systems from declining and protect themselves against infection, scientists say. For the research, scientists from King’s College London followed 125 long-distance cyclists, some of who were in their 80s. They found that some had the immune systems of much, much younger individuals. For example, Prof Norman Lazarus, 82, of King's College London, who co-authored the research and took part in it, was found to have the immune system of a 20-year-old. "If exercise was a pill, everyone would be taking it. It has wide-ranging benefits for the body, the mind, for our muscles and our immune system,” he said. Speaking about the research, Prof Janet Lord, director of the Institute of Inflammation and Ageing at the University of Birmingham and co-author, said people’s immune systems decline at a rate of about 2-3% a year from the age of 20. That’s why older individuals are more susceptible to infections, rheumatoid arthritis and, potentially, cancer. Because the cyclists were found to have the immune systems of much younger people, they have added protection against conditions that tend to affect older individuals. Furthermore, the researchers believe that physically active, older individuals respond better to vaccines, meaning they are also better protected against influenza. The good news is that you don’t need to be a competitive cyclist to reap the benefits. Just being more active and puffing yourself out from time to time can help.
The food you eat could influence the growth rate and spread of cancer, a new study has found. According to scientists at the Cancer Research UK Cambridge Institute, breast tumours in mice struggled to grow without the dietary nutrient asparagine, which is found in asparagus, poultry, seafood and many other foods. When mice with an aggressive form of breast cancer were placed on a low-asparagine diet or given drugs to block the amino acid, their tumours struggled to spread. Scientists hope to be able to take advantage of cancer’s so-called culinary addictions in the future and develop new treatments based on certain foods. Prof Charles Swanton, Cancer Research UK's chief clinician, said: "Interestingly, the drug L-asparaginase is used to treat acute lymphoblastic leukaemia, which is dependent on asparagine. "It's possible that in future, this drug could be repurposed to help treat breast cancer patients." But before you ban asparagus from your home, be aware that more research is needed, including trials in humans. Also, because asparagine is present in so many foods, it is almost impossible to avoid. Baroness Delyth Morgan, the chief executive at Breast Cancer Now, said people should not drastically alter their diets as a result of this research. "We don't recommend patients totally exclude any specific food group from their diet without speaking to their doctors,” she said.
A pioneering breakthrough in the treatment of Huntington’s disease has seen the defect that causes it corrected for the first time. According to the research team from University College London, there is a real possibility that the deadly neurodegenerative disease could be stopped going forward. The team of scientists injected an experimental drug into spinal fluid which reduced the levels of toxic proteins in the brain. Experts are hailing the groundbreaking procedure as the potentially the biggest breakthrough in neurodegenerative diseases for 50 years. Huntington’s disease is a particularly devastating illness that is passed down through families. Some sufferers have likened it to having Parkinson's, Alzheimer's and motor neurone disease all at the same time. A genetic error causes the protein huntingtin – which is vital for brain development – to instead kill brain cells. The unstoppable degradation of brain cells in Huntington's patients leaves them in permanent decline and affects their movement, behaviour, memory and ability to think clearly. Huntington’s blights families and generally hits people while they are in their prime – 30s and 40s. Patients tend to die around 10-20 years after symptoms first appear. The revolutionary drug therapy works by effectively silencing the effects of the mutant huntingtin gene and preventing the harmful protein from ever being built. Professor Sarah Tabrizi, the lead researcher and director of University College London’s Huntington’s Disease Centre, said: “For the first time a drug has lowered the level of the toxic disease-causing protein in the nervous system, and the drug was safe and well-tolerated. This is probably the most significant moment in the history of Huntington’s since the gene [was isolated].”
It’s natural for grandparents to dote on their grandchildren and give them sweet treats whenever they see them. But new research suggests this and other influences could have a negative impact on their grandchildren’s health. For the research, the team from the University of Glasgow analysed 56 different studies which included data from 18 countries, including the UK, US, China and Japan. They focused on the influence of grandparents who were significant in their grandchildren’s lives, but who weren’t necessarily primary caregivers. Three areas of influence were considered: diet and weight, physical activity and smoking. When it came to their grandchildren’s diet and weight, grandparents were found to have an adverse impact, with many studies highlighting how they feed their grandchildren high-sugar or high-fat foods - often in the guise of a treat. The researchers also found that grandchildren were perceived to get too little exercise while under the supervision of their grandparents. However, this did depend on whether the grandparents were physically active themselves or not. Furthermore, smoking around grandchildren became an area of conflict between parents and grandparents, with the latter often smoking while their grandchildren were present, even though they had been asked not to. Talking about the findings of the study, lead researcher Dr Stephanie Chambers said: "While the results of this review are clear that behaviour such as exposure to smoking and regularly treating children increases cancer risks as children grow into adulthood, it is also clear from the evidence that these risks are unintentional. "Given that many parents now rely on grandparents for care, the mixed messages about health that children might be getting is perhaps an important discussion that needs to be had."
A new meningitis test that can provide results within 60 minutes, expediting diagnoses and saving more lives, has started to be used by an A&E department in a hospital in Northern Ireland. Researchers say that the new test will allow doctors at the Royal Belfast Hospital for Sick Children to treat patients fast and accurately, rather than "just in case". A positive meningitis diagnosis can take up to two days, yet infections can overwhelm a person’s body and kill in just hours, which is why fast treatment is so crucial. Furthermore, symptoms may not be obvious until it is too late. Doctors currently have to rely on clinical judging to decide whether antibiotics should be urgently administered and tend to err on the side caution, meaning some patients receive drugs that they don’t necessarily need. The rapid LAMP (Loop Mediated Isothermal Amplification) test on blood, spinal fluid or nasal swab samples will be trialled over a two-year period at the hospital and used to help doctors see if their clinical hunches are correct. Antibiotics will also still be used during the pilot as an extra precaution when doctors determine they are needed. Researcher Dr Tom Waterfield from Queen's University, Belfast, said the LAMP test could also help spot less obvious cases that might otherwise slip through the net. "With the best will in the world you can still miss cases if a child looks quite well and you think it is viral rather than bacterial. "The test could also provide reassurance earlier to anxious parents that their sick child is getting the right treatment. Two days is a long time to wait for a confirmed diagnosis".
A compound found in the slimy mucus from a particular species of frog in India destroys the influenza (flu) virus, according to a new study published in the scientific journal Immunity. Researchers from the Emory Vaccine Centre and the Rajiv Gandhi Centre for Biotechnology in India say the frog slime destroys the H1 variety of influenza viruses. It's hoped that the discovery will lead to powerful new flu remedies being developed in the future. The frog, called hydrophylax bahuvistara, is a type of fungoid frog which was first discovered in 2015 and lives in the forests of south west India. It has an eye-catching orange stripe down the back of its body. For the study, the researchers collected secretions from the frogs' skin before releasing them back into the wild. They then began analysing the different chemicals found in the slime. They managed to isolate small structures that act as "anti-flu peptides", which were used to successfully vaccinate mice against the swine flu virus (Influenza A of H1). The peptides were found to not only blow up the virus, but also leave healthy tissue intact. Speaking to NBC News, Dr Jacob, senior study author and associate professor in microbiology, said: "This peptide kills the viruses. It kind of blows them up. There's no collateral damage." The team decided to call the flu-destroying compound urumin, after an Indian whip-like sword used in martial arts in the south of India called an urumi.
A Mediterranean-inspired meal with lashings of virgin olive oil may help to protect your heart, according to new research. Cholesterol is carried around the blood by two different types of molecules called lipoproteins: low-density lipoprotein (LDL) and high-density lipoprotein (HDL). You'll most likely know LDL as "bad cholesterol". That's because high levels of LDL can lead to plaque building up in arteries, which can result in heart disease and stroke. HDL, on the other hand, the so-called "good bacteria", actually absorbs cholesterol and carries it to the liver where it is flushed from the body. That's why having high levels of HDL can reduce your risk of heart disease and stroke. Previous research has shown that the Mediterranean diet can protect against the development of heart disease as it improves the lipid profile of HDLs. The new research - which was led by Montserrat Fitó, Ph.D., coordinator of the Cardiovascular Risk and Nutrition Research Group at the Hospital del Mar Medical Research Institute in Barcelona, Spain - aimed to determine whether eating a Mediterranean diet rich in virgin olive oil or nuts over a long period of time would improve the beneficial properties of HDL in humans. Fitó's team randomly selected a total of 296 people who already had a high risk of heart disease and were participating in a separate study. They had an average age of 66 and were assigned to one of three diets for a year. They found that the individuals on the Mediterranean diet enriched with virgin olive oil had improved HDL functions. "Following a Mediterranean diet rich in virgin olive oil could protect our cardiovascular health in several ways, including making our 'good cholesterol' work in a more complete way," said Fitó.
A leading bariatric surgeon in the UK has urged the government to offer gastric surgery to patients regardless of their weight. According to Professor Francesco Rubino, the Chair of Bariatric and Metabolic Surgery at Kings College, thousands of type-2 diabetes patients in the UK are missing out on vital weight loss surgery because they do not meet the NHS's guidelines when it comes to weight. That's because, at present, only type-2 diabetes patients who have a BMI of over 30 are currently eligible for bariatric surgery. Rubino says that weight loss surgery is "the closest thing to a cure" and should be used more often. In the UK, there are around 3.6 million people with type-2 diabetes, which costs the NHS up to £10 billion a year to treat. However, approximately 15% of sufferers are "normal weight" and so don't qualify for weight loss surgery under the NHS's current guidelines. "The biggest barrier we have is primarily one of stigma against obesity. The vast majority of the public believes this is a cosmetic intervention and unfortunately many physicians think the same way," said Rubino. Rubino also highlighted that weight loss surgeries, which manipulate the stomach or small intestine, do not just help people lose weight, but actually influence insulin production by altering hormones in the person's gut. "More than 50% of people with type 2 diabetes can enjoy long term remission. Another 30 or 40% enjoy a major improvement," he added.

A new study by the University of Cambridge in the UK has found that viruses are more dangerous when they infect people in the mornings. In fact, the findings of the study, which were published in the medical journal PNAS, show that virus infections that occur in the morning can be up to 10 times more dangerous for the individual. For the study, the Cambridge researchers infected mice at different times of the day with either influenza or herpes. They then looked whether there was any correlation between the time of day when the infection occurred and the potency of the virus. Mice that were infected in the morning were found to have viral levels 10 times higher than those infected in the evening. Unlike bacteria or parasites, viruses rely on the cells of their host to replicate and grow. However, those cells change dramatically throughout the day as part of our 24-hour body clocks. The researchers say their findings could pave the way for stopping pandemics. For example, when faced with a pandemic, it could be life-saving for people to stay inside during the daytime. A virus infection in the evening is like someone trying to hijack a factory once all the workers have gone home. In other words, it's likely to be unsuccessful.
Most people get cravings for high-calories foods, such as chocolate and pizza, from time to time. But new research suggests that such cravings can be reduced by consuming a supplement called inulin-propionate ester. Researchers from Imperial College London and the University of Glasgow found that study participants who drank milkshakes containing the gut bacteria-based supplement were less likely to crave high-calorie foods. Presenting their findings in The American Journal of Clinical Nutrition, the researchers said the supplement works by increasing the amount of propionate in the gut - a compound that is released naturally when a person consumes the fibre inulin, which is found in artichokes, bananas and asparagus. Inulin slows digestion, increase fullness and reduces appetite, and it is already used as a dietary supplement today. For the study, the researchers asked a group of 20 healthy men to drink milkshakes. Half of the group's milkshakes contained inulin-propionate ester, while the other half contained just inulin alone. The researchers then showed the men pictures of different foods; some high calorie, some low calorie. The study participants' brain activities were monitored throughout to see how they reacted to the various pictures. The group that drank the milkshakes containing inulin-propionate ester displayed reduced activity in their brains' reward centres - the caudate and the nucleus accumbens (both associated with food cravings) - but only when they were looking at images of high-calorie foods. In addition to being showed the food images, the men were then given equal-sized bowls of pasta and told to eat as much as they wanted. The inulin-propionate ester group consumed around 10% less than their inulin only counterparts. Dr. Douglas Morrison from the University of Glasgow, who co-authored the study, said that the research illustrates how important gut microbiota signals are for regulating appetite and influencing people's food choices.
It's been thought for some time now that a mother's weight and diet during pregnancy has the potential to affect the breast cancer risk of her female offspring. But now new research suggests that obese father's also risk raising their children's chances of breast cancer, due to the way obesity alters the gene expression of sperm. Experts have long agreed that a woman's breast cancer risk is influenced by changes in genes, and approximately 5-10 percent of these gene changes are inherited. According to Sonia de Assis, Ph.D., from the Department of Oncology at Georgetown Lombardi Comprehensive Cancer Centre in Washington, D.C., who led the investigative team, said few studies have previously investigated the link between a father's weight and an offspring's breast cancer risk in later life. Presenting their findings in the journal Scientific Reports, de Assis and her colleagues outlined how they had studied how both normal weight male mice and obese male mice influence the breast tissue off their offspring. They found that female pups sired by obese males had delayed breast tissue development, and were more likely to develop breast cancer as a result. They revealed that the obese males' sperm had an altered microRNA (miRNA) signature, which was subsequently found in the breast tissue of their female offspring. The researchers now plan to conduct more studies to see if the same is true in humans.
By 2050, superbugs will kill someone every three seconds unless the world acts now. That's the stark warning to come out of a highly-influential new report from the UK. According to the British government-commissioned review, medicine risks "being cast back into the dark ages", and only billions of dollars of investment can save the world from these so-called "superbugs". The global review sets out a plan to prevent this from happening, and calls for a massive campaign to revolutionise the way in which people use antibiotics. At present, the problem is two-fold: we are not developing enough new antibiotics and we are currently misusing the ones we do have. Since mid-2014, when the Review on Antimicrobial Resistance started, more than one million people have died from infections that are resistant to drugs. What's more worrying is that the review predicts that the situation will only get worse, with 10 million people per year predicted to die from resistant infections by 2050. Jim O'Neill, the economist who led the review, said: "If we don't do something, we're heading towards a world where there will be no antibiotics available to treat people who need them." Last year, British Prime Minister David Cameron asked O'Neill to conduct a full review of the problem and suggest ways to combat it. O'Neill's final report - which you can access here - identifies 10 areas that require action from world leaders. Infections that shouldn't be treated with antibiotics include: colds, flu, most coughs and bronchitis, some sore throats, many sinus infections and many ear infections.
Flu vaccinations may do a lot more than just reduce your flu risk, if the findings of a new study in Taiwan are anything to go by. That’s because the researchers responsible say that a flu shot can also protect people from a common heart rhythm disorder, which significantly increases the risk of stroke. The study of around 57,000 people in Taiwan found a significant association between the flu and atrial fibrillation (AF or A-fib); a condition that causes a person’s heart to be faster and more irregular. Research has shown in the past that AF increases a person’s risk of stroke by five times. During the study, the researchers discovered that people who had not had a flu shot and got the flu had an 18% greater risk of developing AF than those who did not have the flu. Published in the Heart Rhythm journal, the findings of the research showed that a person’s risk of developing AF was consistently lower when they had received a flu jab. Dr. Tze-Fan Chao and Dr. Su-Jung Chen, of Taipei Veterans General Hospital, who lead the research, said: "Influenza vaccination should be encouraged for patients, especially those who have a high risk of atrial fibrillation, to try to prevent the occurrence of atrial fibrillation and subsequent stroke. However, a further prospective study is necessary to confirm our findings.”
People have talked about the possible negative effects of processed meat for a long time and numerous studies linking high consumption of red and processed meats with higher risk of colorectal cancer have even influenced public health recommendations in some countries. But now a report compiled on behalf of the World Health Organisation by a working group of 22 experts from 10 countries around the world has concluded that there is an association with eating processed meats and colorectal cancer risks. The findings, published recently in The Lancet Oncology, said that 50g of processed meat a day, which is equivalent to less than two slices of bacon, increased a person’s chances of developing colorectal cancer by 18%. Furthermore, the study said that red meats were “probably carcinogenic, but there was limited evidence to comment further. However, despite these findings, the WHO also emphasised that there are still health benefits associated with eating meat. Cancer Research UK’s advice is that people should cut down on their consumption of red and processed meats, rather than give them up completely. In fact, the organisation said that the occasional bacon sandwich would do little harm. Processed meat is meat that has had its shelf life extended or its taste changed by means of smoking, curing, or adding preservatives or salt. Bacon, sausages, hotdogs, corned beef, salami, ham, beef jerky and other canned meats are all considered “processed”. Chemicals used during the processing of the meats are thought to be carcinogenic catalysts, as is high-temperature cooking such as on a barbecue. Dr Kurt Straif from the WHO said: “For an individual, the risk of developing colorectal (bowel) cancer because of their consumption of processed meat remains small, but this risk increases with the amount of meat consumed.”
Scientists have developed a way of flushing HIV out of its hiding places in the body using a cancer drug, combating its survival mechanism and killing it in the bloodstream. Dormant HIV reservoirs are targeted by the “highly potent” cancer drug and while more testing is needed, experts have described the treatment as “interesting”. Researchers at the UC Davis School of Medicine in California believe that a skin cancer drug known as PEP005 may be able to “kick and kill” these hidden HIV reservoirs. At present, anti-retroviral therapy – the “cornerstone” of cancer treatment – kills HIV in the bloodstream, but leaves its reservoirs untouched. According to their report, "PEP005 is highly potent in reactivating latent HIV". It’s one of a number of "lead compounds for combating HIV". It’s the “kick and kill” strategy that interests scientists the most. The kick effectively wakes up the dormant virus allowing the drugs to kill it. Dr Satya Dandekar, who led the research study, said: "We are excited to have identified an outstanding candidate for HIV reactivation and eradication that is already approved and is being used in patients. "This molecule has great potential to advance into translational and clinical studies." The down side is that the drug has still not yet been tested in people who are HIV-positive. So while the research carries immense amounts of potential, a significant amount of testing and further investigation is needed.
GREEN LASER Green Laser vaporisation of prostate adenoma is a way to treat benign prostatic hypertrophy. It is performed under anaesthetic using keyhole surgery (without opening and along the channel ) with ultrasound guidance. This intervention aims to improve urination (power and quality of the urinary stream) by removing the obstruction caused by the prostate). The consequences of this treatment are: urgent needs, blood in the urine, some mictional pain during the healing phase (which can last up to 2-3 months) and a permanent loss of ejaculation but no erectile disorder and pleasure being unchanged. The limitations of this technique are: imperfect and incomplete results when the prostate is large (>60g) suboptimal indication (insufficient obstruction and predominant irritative complaint) urgent, frequent needs… absence of histopathologic analysis of the vaporised tissue The advantage of this laser treatment is to reduce bleeding, simplify and reduce postoperative recoveries when compared with other techniques and to allow ultrasound monitoring to check the optimal nature of the intervention. It also allows to use saline serum to reduce the risks associated with the use of other irrigation fluids. This technique also allows the maintenance of some anti-platelet drugs (Aspirin…) but require VKA anticoagulant to possibly be stopped.
With just a single drop of your blood, VirScan can identify every virus you’ve ever had in your life and it can do so for around just $25. The research, which was recently published in the journal Science, could be vital for the diagnosis and treatment of viruses going forward. Contagious viruses with few obvious symptoms, like Hepatitis C, could become a thing of the past. Stephen Elledge, the lead author of the study, said: “There are people walking around with chronic Hepatitis C infections that have no idea they have them. Now imagine if this was a routine test that was done every time you went to the doctor. With things like Hep C, the earlier you treat them, the better." Imagine being able to walk into your doctor’s surgery and have a quick test to discover what previous viruses you’ve had, instead of filling out one of those tedious and often long-winded forms. Plus, the test may even pick up some viruses that you didn’t know you’d had! Once your body has defeated a virus, some of the special white blood cells that were released by your immune system at the time are then kept for reference purposes. Your body uses them as a reminder and to keep you protected from that same virus in the future. The study itself involved 569 people from the United States, Thailand, Peru and South Africa. It found that on average the participants tested positive for 10 species of virus. The most common being the flu, the common cold and gastrointestinal viruses. Photo credit: L'Express
URETEROSCOPIC STONE REMOVAL What is a urinary tract stone? Waste products (from the food we eat) that usually dissolve in water are eliminated from the human body in the urine. If there is a lack of solvent (urine) or an excess of solute (the waste product the kidney stone is made of, eg. calcium, uric acid, oxalate, etc), then a supersaturated solution occurs. The solute settles (crystallises) out of the solution, in the kidney and forms a stone. Urine normally has chemicals that inhibit stones forming. In some people with kidney stones, these inhibitors seem not to work properly. The ureteroscopic stone removal procedure consists in freeing the ureter (using a mini-invasive rigid device), or the kidney (using a flexible device) from the stones by breaking them in pieces and removing if possible the fragments. The surgeon inserts an endoscope into the bladder through the urethra. Under X-ray screening, a flexible guide wire is inserted into the affected ureter between the kidney and the bladder, it will guide the endoscope into the ureter. A longer endoscope (either rigid or flexible) is then inserted into the ureter and may be passed up to the kidney if necessary. The stone is disintegrated using ballistic probe or laser fragmentation and the majority of fragments extracted with special retrieval devices At the end of the procedure a soft plastic tube or stent (JJ stent) may be set up between the kidney and the bladder to avoid renal colic induced. The Ureteroscopic treatment allows breaking down urinary stones into small fragments and getting rid of them during the procedure for immediate relief. This treatment is used when less invasive treatments can not be used or have not proved to be efficient; indeed sometimes the stone is too large to break up with ESWL, or not suitable for ESWL, and endoscopic surgery is then required. About the medical devices and the surgical technique used For ureteral stones is used a mini-invasive rigid ureteroscope with a guide wire, a ballistic probe or a laser Holmium fibre for stone fragmentation, and a basketorgraspingforcepsdevice forstoneextraction. For kidney stones it is used a flexible ureteroscope with a ureteral introducer, two guide wires, a laser fibre, and a basket catheter for stone extraction. The procedure is screened both by X-rays and a video camera. A ureteral stent may be set up at the time of surgery. Its goal is to facilitate the urine flow from the kidney to the bladder, and to avoid renal colic. It will also dilate the ureter and then permit stone’s fragments migration after removal. The JJ stent removal is usually done under local anaesthesia between 1 and 4 weeks later. Implants used all come from suppliers that are: o Renowned worldwide, o Accredited by European medical device standards, o Selected for their quality and longstanding reputation. When checking out of the hospital, a document bearing the prosthesis’ serial number will be given to you to enable long-term follow up in the best possible conditions. And then? During the following days, you should drink between 1,5 and 2 litters /day to flush your urinary system and minimise any bleeding. You may experience pain in the kidney over the first 24-72 hours, due to the insertion of the instrument or by the presence of a stent. In case of stent it is better to avoid walking too much. If need be, anti-inflammatory painkillers will help this pain which normally settles after 72 hours but will be continue if necessary. It will take at least 10 days to recover fully from the operation. You should not expect to return to work within 7 days. You can prevent further stone recurrence by implementing changes to your diet and fluid intake. Blood, urine analysis and spectrophotometry analysis of stones’ fragments will help to find the best diet for you.
SLEEVE GASTRECTOMY Sleeve Gastrectomy is a restrictive technique which consists of removing approximately two thirds of the stomach and, in particular, the part containing the cells that secrete the hormone that stimulates appetite (ghrelin). The stomach is reduced to a vertical tube and food passes quickly into the intestine. Appetite is also reduced. This technique does not interfere with the digestion process. Sleeve gastrectomy is sometimes the first step in a biliopancreatic diversion procedure. Expected Weight Loss: Around 45 to 65 % excess weight loss after 2 years, corresponding to a weight loss of approximately 25 to 35 kg. (studies with 2 years follow-up, for a person of average height (1.7 m) with a BMI of 40 kg/m) Mean operating time: 2 hours (Provided there are no complications during the operation). Mean length of hospital stay: 3 to 8 days (Provided there are no complications after the operation). Main complications risks : Ulcers, leakage or stenosis of the remnant stomach. Early postoperative bleeding. Possible nutritional deficiencies (to be monitored). Gastrooesophageal reflux (acids and foods coming back up the oesophagus) and inflammation of the oesophagus.Dilation of the stomach.
