Women with polycystic ovary syndrome (PCOS) may be at a higher risk of developing pancreatic cancer, say researchers reporting a single-center case-control study.

A diagnosis of PCOS was associated with a 1.9-fold higher risk of pancreatic cancer after adjusting for age, race, ethnicity, estrogen level, and diabetes.

This is the second study to find such an association.

A brain-computer interface (BCI)–based video gaming system improves attention in children with attention-deficit/hyperactivity disorder (ADHD) by rewiring abnormal brain networks that regulate attention, suggest preliminary findings of the first brain imaging study to test the system.

@cherry During the first year of the pandemic, meaningful evolution of the virus was slow-paced, without any functional consequences, but since that time we have seen a succession of important variants of concern, with increasing transmissibility and immune evasion, culminating in the Omicron lineages

After some training, dogs may be able to sniff out and identify people who are infected with the coronavirus, according to a new study published in the journal BMC Infectious Diseases. Eight dogs, which are part of the German Armed Forces, were trained for a week to detect the virus in samples of saliva. Then they were given more than 1,000 infected and non-infected samples and were able to detect 94% of cases. They correctly identified 157 positive samples and 792 negative samples but missed 30 positive samples and gave false positives for 33 samples. The study was a small pilot project tested by the German Armed Forces, the University of Veterinary Medicine in Hannover and the Hanover Medical School.

Drinking more than two alcoholic beverages a day in middle-age raises stroke risk in early old age more than do traditional risk factors, such as high blood pressure and diabetes, a new study suggests. The study found that individuals who consumed more than two drinks a day during midlife had double the risk for stroke between the ages of 60 and 75 years compared with those who consumed an average of half an alcoholic drink per day.

@insiya Even low levels of alcohol consumption are associated with an increased risk for at least seven types of cancer (oral cavity, pharynx, larynx, esophagus, liver, breast, and colorectal cancers), the investigators say, noting that the alcohol industry uses denial or omission to dispute this. Distortion tactics mention cancer but misrepresent the actual risk, and distraction is used to veer the message away from the independent effects of alcohol on common cancers, especially breast cancer and colorectal cancer.

Hello, What are the acute and chronic causes of diarrhoea, and what are the investigations required? For last 7 days I am suffering from diarrhoea. Is it normal? Please help me.

Hello, my friend is 45 years old. She is undergoing hemodialysis. I heard that people receiving hemodialysis are at increased risk of developing sepsis. What are the complications of this process? Please leave your comments on this.

@abhilasha-roy Traveler's diarrhea may get better without any treatment. But while you're waiting, it's important to try to stay hydrated with safe liquids, such as bottled water or water with electrolytes such as an oral rehydration solution. If you don't seem to be improving quickly, several medications are available to help relieve symptoms.
Anti-motility agents. These medications — which include loperamide and drugs containing diphenoxylate — provide prompt but temporary relief by reducing muscle spasms in your gastrointestinal tract, slowing the transit time through your digestive system and allowing more time for absorption.
Bismuth subsalicylate. This over-the-counter medication can decrease the frequency of your stools and shorten the duration of your illness. However, it isn't recommended for children, pregnant women or people who are allergic to aspirin.
Antibiotics. If you have more than four loose stools a day or severe symptoms, including a fever or blood, pus or mucus in your stools, a doctor may prescribe a course of antibiotics.

@ganesh Fitness trackers have been on the rise for years: FitBit shipped 9.9 million of its wearable devices in 2019. But the next trend in wearables for medical technology is more specific. For diabetes patients, wearable continuous glucose monitors (CGMs) are set to become the new normal. Wearable CGMs remove the need for intermittent glucose testing and instead keep track of one’s blood sugar levels in real time. This allows users to see the immediate impacts of food and exercise, and shape their lifestyles accordingly. It can also catch cases of hyperglycemia immediately. Medical technology companies are jumping in with two feet: Dexcom, a CGM developer, had revenue of $1.9 billion in 2020 and expects a 15 to 20 percent jump in 2021.
