But less likely if sales clerks think they’re trying to lose weight

Sales clerks tend to subtly discriminate against overweight shoppers but treat them more favorably if they perceive that the individual is trying to lose weight, according to a study by Rice University researchers.

The research, conducted in a large Houston shopping mall, will be presented in a poster session at the annual conference of the Society for Industrial and Organizational Psychology (SIOP)

Young adolescents believe that oral sex is less risky to their health and emotions than vaginal sex, more prevalent among teens their age and more acceptable among their peers. They are also more likely to try oral sex, according to a UCSF study published in the April 2005 issue of Pediatrics.

“These findings suggest that adults should discuss more than one type of sexual practice when they counsel teens,” said Bonnie Halpern-Felsher, PhD, associate professor of adolescent medicine

New findings give infants a greater window of opportunity, better survival odds

A study showing that infants under one year of age can accept heart transplants from donors of different blood groups without the risk of organ rejection means a better chance of survival for infant patients and more efficient use of donor organs overall.
Results will be presented at the International Society for Heart and Lung Transplantation (ISHLT) Annual Meeting and Scientific Session in Phil

Descriptors from the Breast Imaging Reporting and Data System (BI-RADS) lexicon for ultrasound can be useful in differentiating benign from malignant solid masses, according to a new study by researchers at Duke University School of Medicine in Durham, NC, and supported by the National Institutes of Health.

For the study, the researchers analyzed 403 sonograms of solid masses, 141 of which were found to be malignant at biopsy. Each lesion was described using features from the BI

Bone SPECT is better than FDG PET for detecting breast cancer that has spread (metastasized) to a patient’s bones, according to researchers from Shizuoka Cancer Center Hospital in Japan.

FDG PET is an imaging technique based on the increased metabolism of glucose in tumor cells. SPECT is a type of nuclear medicine scan that detects special radioactive elements administered to the patient by the physician. According to the authors, due to these differences in method, bone SPECT

Researchers at the University of Illinois at Urbana-Champaign report dramatic evidence of the importance of visual cues in the control of food intake in the current issue of Obesity Research, a leading nutrition journal.

The researchers served a free soup lunch to 54 adults, half of whom ate from normal 18-ounce soup bowls, while the other half ate from identical bowls that, unbeknownst to the participants, were slowly refilled through tubing connected to out-of-sight soup cauldro
