Consumer Health: Treating stomach cancer

Posted by in categories: biotech/medical, health

November is Stomach Cancer Awareness Month, which makes this a good time to learn more about treating stomach cancer.

More than 26,000 people in the U.S. will be diagnosed with stomach cancer this year, and more than 11,000 people will die of the disease, according to the American Cancer Society. Stomach cancer accounts for about 1.5% of all new cancers diagnosed in the U.S. each year.

Stomach cancer, also known as gastric cancer, can affect any part of the stomach. In most of the world, stomach cancers form in the main part of the stomach. In the U.S., stomach cancer is more likely to affect the area where the esophagus meets the stomach. Where the cancer occurs in the stomach is one factor health care professionals consider when determining treatment options.

A simpler path to better computer vision

Posted by in categories: biotech/medical, internet, robotics/AI

Before a machine-learning model can complete a task, such as identifying cancer in medical images, the model must be trained. Training image classification models typically involves showing the model millions of example images gathered into a massive dataset.

However, using real image data can raise practical and : The images could run afoul of copyright laws, violate people’s privacy, or be biased against a certain racial or ethnic group. To avoid these pitfalls, researchers can use image generation programs to create for model training. But these techniques are limited because expert knowledge is often needed to hand-design an image generation program that can create effective training data.

Researchers from MIT, the MIT-IBM Watson AI Lab, and elsewhere took a different approach. Instead of designing customized image generation programs for a particular training task, they gathered a dataset of 21,000 publicly available programs from the internet. Then they used this large collection of basic image generation programs to train a computer vision model.

New Alzheimer’s Genes Discovered in World’s Largest Study

Posted by in categories: biotech/medical, neuroscience

Summary: Researchers have identified two new genes, ATP8B4 and ABCA1, that are implicated in Alzheimer’s disease. The genes impact the brain’s immune system and cholesterol processing, leading to an increased risk of developing Alzheimer’s disease.

How Your Brain’s “Fingerprints” Could Diagnose Disease

Posted by in categories: biotech/medical, neuroscience

This new way to diagnose schizophrenia, epilepsy, Alzheimer’s disease and autism spectrum disorder could help improve mental health. We often think of fingerprints as the tiny ridges, whorls and arched patterns on the tip of each finger. They are heralded as special markers of human identity, even more individualized than DNA.

How polio came back to New York for the first time in decades, silently spread and left a patient paralyzed

Posted by in categories: biotech/medical, health

It’s difficult to trace the epidemiology since the patient didn’t travel, the mutations in the viruses are small and international travel in and out of New York is heavy, he said.

“With a single case there’s no way to know exactly how many infections there were between the vaccine vial and the paralyzed person,” Oberste said.

It’s unlikely public health authorities will figure out the origin of the virus that paralyzed the patient in New York, Oberste said. Dozens of countries around the world — primarily in Africa, the Middle East and South Asia — are still using oral vaccines that contain the Sabin Type 2 strain.

This AI Uses a Scan of Your Retina to Predict Your Risk of Heart Disease

Posted by in categories: biotech/medical, health, information science, robotics/AI

They then used QUARTZ to analyze retinal images from 7,411 more people, these aged 48 to 92, and combined this data with information about their health history (such as smoking, statin use, and previous heart attacks) to predict their risk of heart disease. Participants’ health was tracked for seven to nine years, and their outcomes were compared to Framingham risk score (FRS) predictions.

A common tool for estimating heart disease risk, the FRS looks at age, gender, total cholesterol, high density lipoprotein cholesterol, smoking habits, and systolic blood pressure to estimate the probability someone will develop heart disease within a given span of time, usually 10 to 30 years.

The QUARTZ team compared their data to 10-year FRS predictions and said the algorithm’s accuracy was on par with that of the conventional tool.

How to avoid sudden cardiac arrest in elderly

Posted by in categories: biotech/medical, food

Veteran actor Tabassum Govil best known for hosting India’s first TV talk show Phool Khile Hain Gulshan Gulshan passed away at the age of 78 following a cardiac arrest on Friday (November 18). Elderly or people over 70 are more at risk of sudden cardiac arrest than the rest as one may have more chronic conditions like diabetes, high BP, smoking, previous heart attacks, weak heart. According to studies, elderly individuals have lower resuscitation and survival rates than younger individuals after in-hospital cardiac arrest. Staying active, eating healthy — food rich in fibre, devoid of saturated fats, added sugar and salt and high in whole grains can help keep your heart strong and healthy. Managing risk factors for heart attack is also advisable. (Also read: Tabassum of Phool Khile Hain Gulshan Gulshan fame dies at 78)

“In elderly, we have to identify the risk factors for sudden cardiac arrest, like, diabetes, high BP, smoking, previous heart attacks, weak heart. If any of these are present, a cardiologist’s consultation should be taken who would conduct simple tests like ECG, Echo and TMT to ascertain risk of sudden cardiac arrest. If the risk is high, they should be counselled to control their diabetes, blood pressure, and regular medical check-ups to detect any red flags,” says Dr. Nishith Chandra, Principal Director — Interventional Cardiology, Fortis Escorts Heart Institute, Okhla Road, New Delhi.

Bilateral anorchia in infancy: Occurence of micropenis and the effect of testosterone treatment

Posted by in category: biotech/medical

Circa 2006


To analyze the clinical and histological findings in boys with bilateral anorchia and the response to testosterone treatment on penis length.

Patients were divided into two groups according to the absence (group A, n = 29) or the presence (group B, n = 26) of palpable intrascrotal or inguinal mass at first clinical examination.
