A study published in the February 2019 "Pediatrics" journal suggests the majority of gay fathers and their children continue to experience stigma with potentially harmful physical and psychological effects, despite legal, media and social advances. Study participants specifically cited structural stigma, such as state laws and beliefs of religious communities, as affecting their experiences in multiple social contexts.

Cancer first develops as a single cell going rogue, with mutations that trigger aggressive growth at all costs to the health of the organism. But if cancer cells were accumulating harmful mutations faster than they could be purged, wouldn't the population eventually die out?

How do cancer cells avoid complete genetic meltdown?

To get at the heart of the matter, a team of scientists from Beijing and Taipei wanted to get a new hint at cancer vulnerability from a mutational perspective by probing the most famous cultured cancer cells, HeLa cells.

LA JOLLA, CALIF. - Jan. 14, 2019 - We all know we should eat fruits and vegetables to keep our own heart healthy. But now, scientists are learning that epigenetic changes, or molecular tags that modify our DNA, can cause your children--and even your grandchildren--to inherit the negative effects of your poor diet. However, the details behind this inheritance--and how to stop it--have been unclear.

Hartford, Conn. - Restaurant, food, and beverage companies (food companies) target Hispanic and Black children and teens with ads almost exclusively for fast food, candy, sugary drinks, and unhealthy snacks, according to a new report from the Rudd Center for Food Policy & Obesity at the University of Connecticut, the Council on Black Health at Drexel University, and Salud America! at UT Health San Antonio.

Sophia Antipolis, 15 January 2019: Patients with type 2 diabetes should be prescribed physical activity to control blood sugar and improve heart health. That is one of the recommendations in a position paper(1) of the European Association of Preventive Cardiology (EAPC), a branch of the European Society of Cardiology (ESC). The paper is published today in the European Journal of Preventive Cardiology, a journal of the ESC.

Poor cardiorespiratory fitness could increase your risk of a future heart attack, even if you have no symptoms of a lifestyle illness today, a new study has found.

"We found a strong link between higher fitness levels and a lower risk of heart attack and angina pectoris over the nine years following the measurements that were taken," says researcher Bjarne Nes, from the Norwegian University of Science and Technology's (NTNU) Cardiac Exercise Research Group (CERG).

The study results have been published in the European Heart Journal.

Half the risk

NEW YORK, NY (January 14, 2019)--A new study of around 8,000 middle-aged and older adults found that swapping a half-hour of sitting around with physical activity of any intensity or duration cut the risk of early death by as much as 35 percent. The findings highlight the importance of movement -- regardless of its intensity or amount of time spent moving -- for better health.

The study was published online in the American Journal of Epidemiology.

A substantial proportion of young Britons are not ready for their first sexual activity- whatever their age-and lose their virginity "under circumstances that are incompatible with positive sexual health," reveals research published online in BMJ Sexual & Reproductive Health.

Rather than focusing on the age at which a young person starts having sex, a much more nuanced approach is needed to this key milestone, say the researchers, in recognition of the fact that "young age alone doesn't threaten sexual health any more than older age safeguards it."

Levels of C-reactive protein (CRP), a chemical associated with inflammation and stress, may be linked to housing type and tenure in the UK, suggests research published online in the Journal of Epidemiology & Community Health.

While observational, the findings nevertheless lend weight to the inclusion of health outcomes in housing policies, say the researchers.

Couples considering medically assisted reproduction (MAR) because they have difficulties conceiving naturally, have feared that they could do harm to their baby by opting for medical intervention. Doctors may warn that MAR raises the risk of preterm birth (less than 37 weeks of pregnancy) and low birth weight (less than 2.5 kilograms).
