As global temperatures rise, so will mental health issues, says a study published Oct. 8, 2018 in the journal PNAS. A rise in average monthly temperatures is tied to a small increase in mental health issues. And over five years, a 1 degree Celsius increase in average temperature results in an even greater prevalence of mental difficulties.

A deadly epidemic may be wiping out the world’s last few Asiatic lions. In the past one month alone, at least 23 of the big cats have died in the Gir Wildlife Sanctuary and National Park in the western Indian state of Gujarat. These deaths include those of three cubs and three adult females. Tests conducted at the Indian Council of Medical Research’s National Institute of Virology, Pune, have officially confirmed the presence of the deadly canine distemper virus (CDV) in at least four of the tissue samples extracted from the carcasses. CDV is extremely infective (sic). In Serengeti (national park in Tanzania) it killed a 1,000 lions in three weeks.
Distemper is closely linked with the measles virus in humans. The two diseases are so similar, in fact, that it is speculated by medical historians and pathologists that the measles virus may have mutated at some point and spread to dogs. Because of this close link between the two, human beings can be infected with the canine distemper virus. However, an important thing to note is that, while the virus can successfully replicate in the human system, it produces no illness and no symptoms.
While distemper is a deadly and very dangerous disease for pet dogs, it is not often a major concern for humans; humans can get the virus, but there are no effects.
Metformin has been the foundational therapy for patients with diabetes, particularly those with established cardiovascular disease. Yet while no large randomized trials have directly compared this long-established therapy against SGLT2 inhibitors and GLP-1 receptor agonists in first-line use, evidence exists to suggest improved cardiovascular benefit with these newer classes of drugs (James Januzzi, MD, of Massachusetts General Hospital in Boston).
Use of acarbose as the add-on remedy to metformin was associated with lower risks of major atherosclerotic events, ischemic stroke, and hypoglycemia, compared with sulfonylurea in patients with type 2 diabetes (Journal of Clinical Endocrinology & Metabolism)

Sexual guidelines for newly-wed persons: Hold for planning a child if one of you has suffered from Zika: Updated guidelines for preventing sexual transmission of Zika virus infection were published by the United States Centers for Disease Control and Prevention (CDC) in August 2018. The new guidelines state that men with relevant history should wait at least three months after Zika virus symptom onset (if symptomatic) or last possible Zika virus exposure (if asymptomatic) before having unprotected sex. Relevant exposure is defined as residence in or travel to an area where mosquito-borne transmission of Zika virus infection has been reported, or unprotected sexual contact with a person who meets these criteria. The previous recommendation, for a wait time of at least six months, was revised based on updated data on the time frame for risk of sexual transmission following infection or exposure.
