Low-dose CT screening may benefit individuals at increased risk for lung cancer

A systematic review found that low-dose computerized tomography (LDCT) screening can reduce lung cancer mortality rates among high-risk individuals. The study analyzed 8 randomized controlled trials and 13 cohort studies, with the National Lung Screening Trial demonstrating a significant benefit. However, potential harms of LDCT screen...

Blocking DNA: HDAC inhibitor targets triple negative breast cancer

A new study published in Breast Cancer Research found that panobinostat selectively targets and destroys triple negative breast cancer cells. The HDAC inhibitor also reduces tumor growth in mice and partially reverses the morphological changes in cells to a more epithelial type.

Drug found for parasite that is major cause of death worldwide

Researchers at UC San Diego School of Medicine have identified an existing drug, auranofin, that effectively targets the Entamoeba histolytica parasite. The parasite causes over 70,000 deaths worldwide each year, and current treatment with metronidazole has adverse effects.

UW study: Sleep apnea associated with higher mortality from cancer

A new study published in the American Journal of Respiratory and Critical Care Medicine found a significant association between sleep-disordered breathing (SDB) and increased risk of cancer mortality. Patients with severe SDB had a nearly five times higher incidence of cancer deaths compared to those without the disorder.

Experimental bariatric surgery controls blood sugar in rats with diabetes

Scientists at the Toronto General Hospital Research Institute showed that an experimental bariatric surgery can lower blood sugar levels in non-obese rats with type 1 diabetes. The study demonstrated that duodenal-jejunal bypass surgery activates novel nutrient-sensing signals in the jejunum, rapidly lowering blood sugar levels.

Growth factor in stem cells may spur recovery from MS

A substance in human mesenchymal stem cells promotes nerve restoration and myelin sheath repair in rodent models of multiple sclerosis. Hepatocyte growth factor, a key instigator, decreases inflammation and increases signaling molecules counteracting it, leading to neural cell growth and nerve rewinding.

Lab tests show arthritis drug effective against global parasite

A team of researchers from UCSF and UC San Diego has identified an approved arthritis drug, auranofin, that is effective against amoebas in lab and animal studies, suggesting it could offer a low-dose, low-cost treatment for dysentery worldwide. The drug has been shown to be 10 times more potent than the current treatment and could be ...

First, do no harm: Study finds danger in standard treatment for a serious lung disease

A new study reveals that a combination of three drugs used to treat idiopathic pulmonary fibrosis can lead to increased risk of death and hospitalization. The researchers found no improvement in lung function or slowing of disease progression with the treatment, highlighting the importance of rigorous testing methods.

OSA can be managed successfully in the primary care setting

Researchers found that primary care-based management was comparable to specialist care in terms of ESS scores, FOSQ scores, and CPAP compliance. Home auto-titrating CPAP usage was also similar between the two groups. The study suggests a lower-cost alternative for OSA treatment, particularly beneficial for rural and remote regions.
