Six to eight hours of sleep best for the heart, says study
Research shows sleep deprivation or excessive hours in bed increase risk of coronary artery disease or strokeSix to eight hours of sleep a night is most beneficial for the heart, while more or less than that could increase the risk of coronary artery disease or a stroke, researchers have suggested.The study, presented at the European Society of Cardiology Congress in Munich, indicates sleep deprivation and excessive hours in bed should be avoided for optimum heart health.Continue reading...

Scientists Identify the First-Known Offspring of Two Different Groups of Early Humans, Study Says
(BERLIN) — Scientists say they’ve found the remains of a prehistoric female whose mother was a Neanderthal and whose father belonged to another extinct group of human relatives known as Denisovans. The 90,000-year-old bone fragment found in southern Siberia marks the first time a direct offspring of these two groups has been discovered, according to a study published Wednesday in the journal Nature. Both groups disappeared by about 40,000 years ago. Neanderthals lived in Europe and Asia, while fossils of Denisovans are known only from the cave where the fragment was found. Past genetic studies have shown interb...

Salt not as damaging to health as previously thought, says study
New research reignites a row with scientists who want to reduce salt intake to near zeroSalt may not be as damaging to health as is usually claimed, according to a controversial new study which suggests campaigns to persuade people to cut down may only be worthwhile in countries with very high sodium consumption, such as China.The World Health Organization recommends cutting sodium intake to no more than 2g a day – the equivalent of 5g of salt – because of the link to increased blood pressure, which is in turn implicated in stroke.Continue reading...

Lowering Your Blood Pressure Could Reduce Alzheimer ’s Risk, New Research Shows
Margaret Daffodil Graham tries to live a healthy life, particularly since she has a health issue that requires constant attention. Like more than 100 million other Americans, the 74-year-old from Winston-Salem, N.C., has high blood pressure, and she has been taking medication to control it since she was in her 30s. So when she read that her nearby hospital, Wake Forest Baptist Medical Center, was looking for people with hypertension to volunteer for a study, she quickly signed up, knowing the doctors would monitor her blood pressure more intensively and hopefully lower her risk of developing heart disease and stroke. What...

Air pollution linked to changes in heart structure
Study shows correlation between levels of exposure to fine particulate matter and chamber enlargement seen in early stages of heart failureAir pollution is linked to changes in the structure of the heart of the sort seen in early stages of heart failure, say researchers.The finding could help explain the increased number of deaths seen in areas with high levels of dirty air. For example, a report last year revealed that people in the UK are64 times more likely to die from the effect of air pollution than people living in Sweden. Such premature deaths can be linked toa number of causes includingrespiratory problems,stroke a...

Exploring solutions for healthy, safe, and sustainable fatty acids (EPA and DHA) consumption in The Netherlands
AbstractAdvisory bodies such as the World Health Organization and the Dutch Health Council (DHC) recommend including fatty fish in one ’s diet, based on the health benefits of their content ofn − 3 poly unsaturated fatty acids (eicosapentaenoic acid—EPA and docosahexaenoic acid—DHA) being, i.e., the reduction of the risk of fatal cardio vascular disease and stroke. These dietary advices on these fatty acids’ (e.g., fatty fish) consumption are only based on the expected health benefits. But what would a dietary advice look like when the health benefits were weighed up against relevant sustainability and food s...

Mandatory criteria for the application of variability-based parameters of fluid responsiveness: a prospective study in different groups of ICU patients.
CONCLUSIONS: The applicability of SVV in a predominantly medical ICU is only about 25%-35%. The prevalence of both mandatory criteria decreases over time during the ICU stay. Furthermore, the applicability is particularly low in patients with acute pancreatitis and liver failure. PMID: 29971990 [PubMed - in process]

Work stress raises risk of premature death in vulnerable men - study
Men with diabetes or heart disease under ‘job strain’ have 68% higher risk of early deathA major study into the impact of work stress on health has revealed dramatic differences in the rates of premature death between different groups of men, and between men and women, depending on existing medical conditions.Doctors found that men with diabetes, heart disease, or who had previously suffered a stroke, were 68% more likely to die over the course of the study if they had demanding jobs with little control over their workload.Continue reading...

Prognostic Factors of Functional Recovery from Left Hemispheric Stroke.
This study aimed to reveal the prognostic variables that relate to functional recovery in stroke patients with a left-sided hemispheric lesion during 6 months of follow-up. Data from 167 left-sided and 183 right-sided hemispheric strokes were reviewed retrospectively. Outcomes in this study included walking capacity and functional recovery, assessed by the modified Rankin Scale (mRS). In order to obtain independent predictive variables, this study used the step-backward method of multivariable regression analysis of parameters. The final model demonstrated that motor function of the hemiparetic leg was the strongest indepe...

Extra glass of wine a day 'will shorten your life by 30 minutes'
Drinking is as harmful as smoking, and more than five drinks a week lowers life expectancy, say researchersDrinking will shorten your life, according to a study that suggests every glass of wine or pint of beer over the daily recommended limit will cut half an hour from the expected lifespan of a 40-year-old.Those who think a glass of red wine every evening will help keep the heart healthy will be dismayed. The paper,published in the Lancet medical journal, says five standard 175ml glasses of wine or five pints a week is the upper safe limit – about 100g of alcohol, or 12.5 units in total. More than that raises the risk ...

The role of long-range coupling in crayfish swimmeret phase-locking.
Abstract During forward swimming, crayfish and other long-tailed crustaceans rhythmically move four pairs of limbs called swimmerets to propel themselves through the water. This behavior is characterized by a particular stroke pattern in which the most posterior limb pair leads the rhythmic cycle and adjacent swimmerets paddle sequentially with a delay of roughly 25% of the period. The neural circuit underlying limb coordination consists of a chain of local modules, each of which controls a pair of limbs. All modules are directly coupled to one another, but the inter-module coupling strengths decrease with the dis...

Blood-thinning drugs designed to cut stroke risk may actually increase it
Scientists call for caution in prescribing anticoagulants after some patients with other conditions found to suffer more strokesBlood-thinning drugs may increase rather than cut the risk of stroke in some people over 65 who have an irregular heartbeat and also chronic kidney disease, according to a new study.The researchers are calling on doctors to be more cautious in prescribing the drugs, called anticoagulants, until there has been more research.Continue reading...

Even one cigarette a day greatly raises cardiovascular risk, experts warn
Impact of one daily cigarette on risk of heart disease and stroke greater than previously thoughtSmoking just one cigarette a day is more dangerous than commonly thought, say researchers who have found it still raises the risk of coronary heart disease or stroke to about half the risk from smoking 20 a day.The team behind the study say that the findings emphasise that cutting out cigarettes, rather than just cutting down, is necessary to dramatically reduce the chance of cardiovascular problems – akey cause of premature death among smokers.Continue reading...
