"Statins not only lower cholesterol but also repair the heart and restore lost function, a new study suggests.

Around six million people in Britain are prescribed statins but many people do not take the drugs over fears they caused debilitating side-effects.

Last year a 30-year study concluded that the benefits of statins far outweighed the risks and claimed they helped prevent around 80,000 heart attacks a year.

Now new research by Queen Mary University of London suggests they are even more beneficial. Not only do they lower cholesterol but they also appear to improve heart health.

The researchers suspect that the drugs reduce oxidative stress and so slows down heart ageing while at the same time boosting blood flow to help repair damage and lower stress.

The team used magnetic resonance scanning (MRI) to peer into the hearts of 4,622 men and women in their 60s from the UK Biobank, of whom 785 were taking statins.

Compared with untreated individuals, patients prescribed the medicines had lower left ventricular heart chambers containing 2.4 per cent less muscle mass, meaning their hearts were fitter and healthier and more able to pump blood effectively.

The effect was striking because those prescribed statins had been judged to the biggest risk of heart problems. They had higher BMIs, higher blood pressure and were on average four years older."

Secar a roupa dentro de casa é de evitar?

"But hanging them to dry inside may be turning your house into an unhealthy breeding ground for different agents which thrive in damp places.

Dr Nick Osborne, Senior Lecturer in Environmental Health at the University of NSW, Australia told Kidspot that drying your clothes indoors contributed to the potential growth of mould and dustmites, both of which can be detrimental to your health.

It's particularly dangerous for people who suffer from asthma as it can trigger the symptoms.

Dr Christine Cowie, a senior research fellow at the University of New South Wales said:

"From a health perspective … many biological agents are found indoors and they usually thrive on dampness and inadequate ventilation. They have found that dampness itself has been a good indicator of risk of asthma and respiratory symptoms. There are other studies that show inhalation of fungal spores … are linked to allergic sensitisation and asthma, (...)""

Privação do sono faz cérebro comer-se a si próprio?

Já se sabia que não dormir nos frita o cérebro (entre aspas), agora há um estudo (em ratos):

"This may cause brain cells to eat other parts of the brain, a new study has found.

The brain contains cells known as astrocytes, which work to clear away worn-out brain cells.

However, researchers at the Marche Polytechnic University in Italy recently discovered that astrocytes work at a higher rate in a sleep-deprived brain, according to New Scientist, potentially causing long-term damage.

The researchers compared the brains of mice that had been allowed to sleep for as long as they wanted with the brains of mice that were kept awake an additional eight hours.

A third group of mice was kept awake for a number of days to induce chronic sleep deprivation.

It was found that astrocytes were 6% active in the synapses (junctions which link nerve cells in the brain) of well-rested mice, compared with activity of around 8% in the mice  which had been kept awake for eight hours.

The mice that were chronically sleep-deprived showed astrocyte activity of around 13.5%, over double that of the well-rested mice.

"We show for the first time that portions of synapses are literally eaten by astrocytes because of sleep loss," said lead researcher Michele Bellesi."

Importância do exercício físico (caminhadas) em pacientes com cancro e em tratamento

"Those in the exercise group were around half as likely to die as those in the usual care group and less likely to have their disease progress, the study, which has not yet been published in a journal, suggested."
(...)
"In the second study, 992 people with stage three bowel cancer that had begun to spread were assessed twice over seven years for diet and lifestyle.

Researchers looked at how closely people followed American Cancer Society guidelines on nutrition and exercise for people with cancer. The guidelines recommend patients keep to a healthy weight, exercise at a moderate-intensity level for 150 minutes per week and eat healthy food.

The study found that compared to those people who adhered least to the guidelines, those who followed them closely had a 42% lower risk of dying and a trend towards better disease-free survival.

Erin van Blarigan, associate professor in University of California San Francisco department of epidemiology and biostatistics, who worked on the study, said it was thought that exercise may affect cancer by lowering levels of insulin and insulin resistance.

Dr Vicky Coyle, a Cancer Research UK scientist at Queen’s University Belfast, said: “Patients with advanced bowel cancer could benefit from keeping a healthy weight, being physically active, and eating a healthy diet, as this study suggests."

"According to preliminary research, social jet lag can cause an increased risk of heart disease, poor health, worse mood and greater fatigue,

The new study found that – even if you do get the recommended eight hours of sleep a night on the weekend – every hour that this is shifted to later in the morning is associated with an 11% increase risk of heart disease."

Consumo de batata frita associado maior risco de morte

"The study tracked the potato consumption of 4,400 adults between ages 45 and 79 over the course of eight years. By the end of the study, 236 people had died.

According to researchers, the twice-weekly fry consumption more than doubled the risk of death. And it's not the potatoes that are the problem — eating them boiled, baked or mashed didn't pose the same risks.

It's the fried ones that'll get you. (Especially the crispy ones.)"
