Pílula contraceptiva ligada a depressão?
... Ou "doorhandle diagnosis" conforme o autor desta notícia suspeita?
http://www.dailymail.co.uk/health/article-3816789/DR-MAX-MIND-DOCTOR-reason-Pill-linked-depression.html
Citando:
"Doorknob revelations can be crucial. A throw-away remark made by a patient as they’re halfway out the door may just be the missing piece of the puzzle; the clue that sounds a klaxon that the patient has a serious physical illness, such as cancer.
However, in my experience, a ‘door-handle diagnosis’ is very often about a patient’s mental health — because, I think, people are too embarrassed or ashamed to make an appointment explicitly to discuss how they are feeling.
Doorhandle diagnosis shows why a really good GP, or nurse, should routinely ask their patient , ever so casually, if everything else is OK."

Ai o [herbicida] Glifosato, outra vez
A FDA está a encontrar Glifosato (presente no Roundup, o sucesso de vendas da Monsanto) em comida de bebé (aveia, trigo):
http://m.huffpost.com/us/entry/12252824
A Monsanto factura 15 mil milhões de USD por ano e cerca de um terço deste valor (5 mil milhões) deriva de produtos contendo glifosatos (recentemente identificados como possível causa de cancro). Muitos detalhes no artigo acima, incluindo o link para o PDF da Monsanto que recomenda uma aplicação final pré-colheita. Genial!

O que é a DLB?
É mais um tipo de demência (que pode representar 15% dos casos e que por vezes é mal diagnosticada - como foi para este famoso actor):
http://metro.co.uk/2016/10/02/a-terrorist-inside-my-husbands-brain-robin-williams-wife-details-the-last-months-of-the-comedians-life-6165686/
Citando:
"Dementia with Lewy bodies (DLB) is a type of dementia that shares symptoms with both Alzheimer’s disease and Parkinson’s disease.
It may account for 10-15 per cent of all cases of dementia.
DLB can be diagnosed wrongly and is often mistaken for Alzheimer’s disease.
Lewy bodies are the cause of DLB and Parkinson’s disease. They are two of several diseases caused by Lewy bodies that affect the brain and nervous system and get worse over time. These are sometimes called Lewy body disorders.
The way someone is affected by DLB will depend partly on where the Lewy bodies are in the brain:
Lewy bodies at the base of the brain are closely linked to problems with movement (motor symptoms). These are the main feature of Parkinson’s disease.
Lewy bodies in the outer layers of the brain are linked to problems with mental abilities (cognitive symptoms), which is a feature of DLB.
Symptons include problems with mental abilities, such as staring into space for a long time or periods when speech is disorganised; depression; day-to-day memory loss; hallucinations and delusions; movement problems; sleep disturbance; a loss of smell; urinary incontinence.

Saúde mental no Reino Unido
... A degradar-se desde o último inquérito:
http://m.huffpost.com/uk/entry/12262340
Citando:
"The seven years since the last Adult Psychiatric Morbidity Survey has seen the start of a major change in the way our society views mental health. A notable shift in public attitudes towards mental health is underway, and mental health issues are now widely recognised.
Factors such as recession, poverty and unemployment have adversely affected the mental health of the nation, leading to an increase in demand for help and support and at the same time, services are under enormous pressure.
The data paints a stark picture. In some groups of the population it is stabilising, while in other groups it is worsening. Nowhere is it improving. We can now start to see the true scale of an issue which has been stigmatised for centuries and it is deeply worrying for all. "

Álcool como anti-depressivo (auto-medicação)?
http://www.medicaldaily.com/depression-alcohol-has-same-effects-rapid-anti-depressants-study-says-399568
Citando:
"Because of the high comorbidity between major depressive disorder and alcoholism there is the widely recognized self-medication hypothesis, suggesting that depressed individuals may turn to drinking as a means to treat their depression," she said in a press release. "We now have biochemical and behavioral data to support that hypothesis."
Raab-Graham cautioned, however, that relying on the intoxicating substance can still pose a threat.
"There's definitely a danger in self-medicating with alcohol," she added. "There's a very fine line between it being helpful and harmful, and at some point during repeated use self-medication turns into addiction."

Acne e longevidade?
http://www.telegraph.co.uk/science/2016/09/28/acne-sufferers-live-longer--research-suggests/
Citando:
"Experts had already noted that signs of ageing such as wrinkles and thinning skin often appear much later in people who have experienced acne.
Now, scientists believe they may have discovered why.
A study of white blood cells taken from individuals affected by spots showed they had longer protective caps on the ends of their chromosomes.
Called telomeres, the caps can be compared with the plastic tips that stop shoe laces becoming frayed.
They help prevent the chromosomes, packages of DNA, deteriorating and fusing with their neighbours during cell division.
Telomeres shrink over time and are closely linked to biological ageing - people with long telomeres age more slowly than people with short ones."
The new research shows that acne sufferers tend to have significantly longer telomeres and may therefore be blessed with the gift of long-lasting youthfulness.

Deitem fora as esponjas de banho dizem dermatologistas
Nada de muito surpreendente mas que ainda não fizemos: Deitar fora as esponjas de banho (usadas para esfoliar, remover as células mortas da pele - o que alegadamente seria positivo). O problema é que estas células retidas na esponja podem ser o ambiente ideal (humidade e calor do banho) para que durante o dia todo o tipo de bactérias e bolores de desenvolvam (e nos afectem através de cortes na pele):
http://nypost.com/2016/09/20/shower-puffs-are-useless-balls-of-germs/
Citando:
"Dermatology Institute, says they can do more harm than good.
That’s because the dead skin cells you scrub off get caught in the folds of netting.
He adds: “Then you put them in this environment in the shower that’s warm and moist and gross, and it’s a setup for bacteria, yeast and mold to grow in the puff.”
If you use them on newly shaved skin, the news is even worse.
The bacteria can then get into any tiny nicks and result in infections and bad skin."

Alguns ingredientes (enzimas) geneticamente modificados podem provocar alergias
E estão em... Comida, detergentes, etc. e tal:
http://www.nhs.uk/news/2016/09September/Pages/GM-chemicals-in-cleaning-products-are-potent-allergens-study-finds.aspx
Citando:
"Researchers took blood samples from 813 workers routinely exposed to genetically modified (GM) enzymes from working in the food, drinks, chemicals, detergents and pharmaceutical industries.
They found antibodies – proteins produced in response to the presence of the GM enzymes – in just under a quarter of those tested.
The most commonly detected antibodies were derived from exposure to alpha amylase, stainzyme, and pancreatinin, which are predominantly used in detergents and home care products.
However, just having antibodies doesn't prove a person has an allergy."

Sintomas de que se está a beber (ou bebeu) demais
Como se fosse preciso, fica aqui o resumo:
"Symptoms of drinking too much
While all drinking has elements of long- and short-term risk, consistent drinking can lead to dependence and other alcohol-related problems. If you find it hard to stop drinking after you have started, you do things that are not normally expected of you because of your drinking, or you feel you sometimes need a drink in the morning, you may be showing signs of dependence and should consult your GP or a health practitioner.
Another sign of dependence is that, over time, greater amounts of alcohol are required to achieve intoxication. Persistent use and being preoccupied with your consumption, despite evidence of harm, is another sign your drinking might be unhealthily habitual.
If you feel guilty after drinking, have injured someone because of your drinking, or someone has suggested you reduce your drinking, you should also consider talking to someone about your alcohol consumption."

As notícias sobre o perigo dos gatos de rua desdramatizadas (NHS)
http://www.nhs.uk/news/2016/09September/Pages/cuddling-a-kitten-almost-certainly-wont-kill-you.aspx
Citando:
"But cat lovers can relax – deaths and serious illness from "killer kittens" with so-called cat scratch disease (CSD) are exceedingly rare.
In fact, the study on which this and other headlines are based did not report any deaths, although it estimated 500 people are admitted to hospital in the US each year with the disease.
CSD is caused by bacteria spread among cats by fleas, which can infect humans through scratches and possibly bites from cats.
It causes swollen lymph glands. Some people get more serious infections, leading to inflammation of the brain or the inner lining of the heart."

Recomendações para dormir bem (sequências/fórmulas)
Um pouco senso comum mas é uma sequência/formulação interessante para relembrar:
http://www.telegraph.co.uk/news/newstopics/howaboutthat/12182052/Be-more-productive-This-simple-10-3-2-1-0-formula-could-help.html
Citando:
"The 10-3-2-1-0 formula
10 hours before bed: No more caffeine
3 hours before bed: No more food or alcohol
2 hours before bed: No more work
1 hour before bed: No more screen time
0: The number of times you hit the snooze button in the morning
“The single most important factor in winning your mornings and owning your days is to get up 15 minutes earlier and work on your No. 1 priority before anyone else is awake. It's that simple,” he explains.
“When you follow this formula, you'll get more done and stop letting the big opportunities in your life slip away.”"
E esta sequência/formulação induz alegadamente o sono num minuto (acaba com as insónias):
http://www.telegraph.co.uk/science/2016/03/12/simple-4-7-8-breathing-trick-can-induce-sleep-in-60-seconds/
Citando:
"The trick is holding the breath for four seconds, breathing out then holding for seven seconds. After that exhale completely for a count of eight. The steps are then repeated between two and four times.
Dr Weil says it works because it allows the lungs to become fully charged with air, allowing more oxygen into the body, which promotes a state of calm.
“You have to do this two times a day religiously. It will become a wonderful way to help you fall asleep. You can do it more often throughout the day,” added Dr Weil."
(...)
"The method is based on an ancient Indian practice called pranayama, which means regulation of breath, and is used widely in yoga and pilates."

Há genes da depressão?
A depressão é genética ou deriva de factores ambientais? Provavelmente é uma mistura dos dois. E nem todas as depressões são iguais, assim como o cancro é um nome comum para várias doenças (tipos de cancro), o que torna a resposta à questão especialmente complexa:
http://www.independent.co.uk/life-style/health-and-families/healthy-living/why-is-there-no-gene-for-depression-a7291016.html
Citando:
"So is there a gene for depression? No, there isn’t. We don’t have genes for diseases, we have genes that encode proteins that serve functions in cells. So does that mean if your DNA has the relevant change in your LHPP or SIRT1 genes that you are going to develop depression? No, it probably means you may have an increased risk to develop depression depending on the environment you experience.
In the same way that we think about heart disease, cancer, obesity as having multiple “susceptibility genes”, the same is probably true for depression. "
