The impact of osteoporosis and vertebral compression fractures on mortality and association with pulmonary function in COPD: A meta-analysis.

Objective: Osteoporosis is highly prevalent among patients with chronic obstructive pulmonary disease (COPD) and most commonly presents as a vertebral compression fracture (VCF). Our objective was to quantify the effect of osteoporosis and VCFs on the mortality and pulmonary function tests (PFTs), such as forced expiratory volume in 1 second (FEV) and forced vital capacity (FVC), of patients with COPD.

Methods: A PubMed/Medline search was conducted using the search terms "chronic obstructive pulmonary disease", "osteoporosis" and "vertebral compression fracture".

Bronchoscopy during the COVID-19 pandemic: effect on current practices and strategies to reduce procedure-associated transmission.

: Bronchoscopy and related procedures have unambiguously been affected during the Corona Virus Disease 2019 (COVID-19) pandemic caused by Severe Acute Respiratory Syndrome-Corona Virus-2 (SARS COV-2). Ordinary bronchoscopy practices and lung cancer services might have changed over this pandemic and for the years to come.: This manuscript summarizes the utility of bronchoscopy in COVID-19 patients, and the impact of the pandemic in lung cancer diagnostic services, in view of possible viral spread during these We conducted a literature review of articles published in PubMed/Medline from inception to November 5th, 2020 using relevant terms.

Effect of season on fatty acid and terpene profiles of milk from Greek sheep raised under a semi-extensive production system.

The objective of the study was to investigate the effect of season on the fatty acid and terpene composition in ewe milk. A total of 760 samples of bulk sheep milk were collected during winter (147 samples), spring (314 samples) and summer (299 samples) of 2011, from 90 commercial farms of dairy sheep from the prefecture of Grevena, Greece. Regarding fatty acid composition, summer samples had higher concentrations of α-linolenic acid, cis-9, trans 11- CLA, trans-11, C18 : 1 and PUFAs but lower content of saturated fatty acids particularly C12 : 0, C14 : 0 and C16 : 0.
