HEPA air cleaners benefit COPD patients

An environmental intervention study by Nadia N Hansel and team has revealed potential health benefits of portable HEPA air cleaners among former smokers with COPD, particularly among those with greater adherence and spending a greater time indoors.

The findings of the study are published in the American Journal of Respiratory and Critical Care Medicine.

SGLT- 2 inhibitors protect kidney, heart

In addition to lowering blood sugar levels, diabetes drugs called Sodium-glucose cotransporter 2 (SGLT2) inhibitors can provide kidney- and cardiovascular-related benefits for people with type 2 diabetes.

A recent study has found that such benefits are also experienced by individuals with type 1 diabetes. There is a significant risk reductions for cardiovascular disease and kidney failure with SGLT2 inhibitor treatment in type 1 diabetes, confirms study.

Pretreatment PET/CT catches cancer metastases

A second PET/CT scan is needed before radiotherapy treatment when there are delays of more than 4 weeks after initial PET/CT staging in patients with advanced head and neck squamous cell cancer, finds a recent study. This is expected to directly influence oncologic outcomes as it led to changes in treatment planning in more than half of the cases.

The study is published in the journal Clinical and Translational Radiation Oncology.

Vitamin D, Omega-3 protect against AI disease

In observational studies, vitamin D has been inconsistently associated with reduced risk of several autoimmune diseases, and a large randomized, controlled trial has been lacking.

Supplementation with vitamin D and fish oil-derived omega-3 fatty acids may prevent from autoimmune diseases, suggests a large prospective randomized trial. A nationwide randomized trial by Jill Hahn and team revealed that supplementation for 5 years with vitamin D3 and or n-3 fatty acids reduced incident autoimmune disease by 25-30% in older adults than those who received neither supplement. The effect of vitamin D3 appeared to be stronger after 2 years of supplementation.

C. Acnes strains promote skin health

Cutibacterium acnes, a bacteria that is known to cause acne, is also widely spread on people with healthy skin. Recent advances in gene sequencing have shown that differences in the genetic background between strains of bacteria may lead to differing roles in the skin. A new study, done without animal (mammal) testing, shows that the nonpathogenic strain of C. acnes improves the skin's resistance against the infection-causing bacteria Staphylococcus aureus.

The report appears in Microbiology Spectrum of the American Society for Microbiology.
