Paternal Alcohol Use Increases Frequency Of Fetal Development Issues - تاثیر منفی مصرف الکل توسط پدر بر سلامت فرزند

Prenatal visits have traditionally focused almost exclusively on the behavior of mothers, but new research from the Texas A&M University College of Veterinary Medicine & Biomedical Sciences (CVMBS) continues to suggest that science should be looking more closely at the behavior of fathers as well.

Publication in The FASEB Journal , Golding’s team showed that the epigenetic factor of prenatal exposure to alcohol in males can manifest in the placenta.

According to Kara Thomas, VTPP graduate student and the lead author on the paper, their data shows that in mice, offspring of fathers exposed to alcohol have a number of placenta-related difficulties, including increased fetal growth restriction, enlarged placentas, and decreased placental efficiency.

“The placenta supplies nutrients to the growing fetus, so fetal growth restriction can be attributed to a less efficient placenta. This is why placental efficiency is such an important metric; it tells us how many grams of fetus are produced per gram of placenta,” Thomas said. “With paternal alcohol exposure, placentas become overgrown as they try to compensate for their inefficiency in delivering nutrients to the fetus.”

cardiovascular risk of consuming small quantities of alcohol - خطرات الکل برای سلامت

Drinking less than the UK’s recommended limit of 14 units of alcohol per week still increases the risk of cardiovascular issues such as heart and cerebrovascular disease, according to new research published in the journal Clinical Nutrition.

The sample included 333,259 people who drank alcohol. Participants had been asked about their overall weekly alcohol intake and their intake of specific types of alcohol including beer, wine and spirits. Those participants were followed up for a median of approximately seven years, capturing all incidences where patients had been hospitalised through cardiovascular events.

Anyone who had suffered a previous cardiovascular event was excluded from the analysis, as were former drinkers or those who had not completed information on alcohol intake.

The analysis found that, for those participants that drank less than 14 units of alcohol per week – the limit recommended by the UK’s Chief Medical Officers – each additional 1.5 pints of beer at 4% strength (alcohol by volume) is associated with a 23% increased risk of suffering a cardiovascular event.

The authors argue that biases in existing epidemiological evidence have resulted in the widespread acceptance of the “J-shaped curve” that wrongly suggests low to moderate alcohol consumption can be beneficial to cardiovascular health.

These biases include using non-drinkers as a reference group when many do not drink for reasons of existing poor health, pooling of all drink types when determining the alcohol intake of a study population, and embedding the lower risk observed of coronary artery disease among wine drinkers, potentially distorting the overall cardiovascular risk from the drink.

New WHO study links moderate alcohol use with higher cancer risk - مشروبات الکلی و سرطان

A new study from the World Health Organization’s (WHO) International Agency for Research on Cancer (IARC), published in the journal Lancet Oncology, has found an association between alcohol and a substantially higher risk of several forms of cancer, including breast, colon, and oral cancers. Increased risk was evident even among light to moderate drinkers (up to two drinks a day), who represented 1 in 7 of all new cancers in 2020 and more than 100,000 cases worldwide.

In Canada, alcohol use was linked to 7,000 new cases of cancer in 2020, including 24 per cent of breast cancer cases, 20 per cent of colon cancers, 15 per cent of rectal cancers, and 13 per cent of oral and liver cancers.

Alcohol May Have Immediate Effect on Atrial Fibrillation Risk - از عوارض حاد مصرف مشروبات الکلی

Alcohol appears to have an immediate—or near-immediate—effect on heart rhythm, significantly increasing the chance that an episode of atrial fibrillation (AFib) will occur, according to new data presented at the American College of Cardiology’s 70th Annual Scientific Session.
The data revealed that just one glass of wine, beer or other alcoholic beverage was associated with twofold greater odds of an episode of AFib occurring within the next four hours. Among people having two or more drinks in one sitting, there was a more than threefold higher chance of experiencing AFib. Using an alcohol sensor placed on participants’ ankles, which passively monitored alcohol intake, the investigators found that every 0.1% increase in inferred blood alcohol concentration over the previous 12 hours was associated with an approximate 40% higher odds of an AFib episode. Evidence from those sensors also demonstrated that the total alcohol concentration over time also predicted the chance AFib would occur.

Low level alcohol use during pregnancy can impact childs brain development - حتی مصرف مقادیر اندک الکل در دوران بارداری می تواند به رشد مغزی جنین صدمه بزند

A new study finds any alcohol use during pregnancy, even low levels, is associated with subtle, yet significant behavioural and psychological effects in children including anxiety, depression, attention deficit hyperactivity disorder (ADHD) and poor attention.
