Association of vitamin D deficiency and pelvic organ prolapse in postmenopausal women: a cross-sectional study.

Background: Vitamin D is vital for skeletal integrity as well as optimal muscle work. High incidence and prevalence of vitamin D deficiency as well as pelvic organ prolapse are found in postmenopausal women, thus raising the question of whether the entities could be related.

Methods: We compared 50 postmenopausal women aged 50 to 75 years with pelvic organ prolapse (POP) with 48 women of same age without POP.

Vitamin D and its role in gynecology: emerging importance of checking vitamin D status in certain gynecological entities.

Among non-bone effects of vitamin D, the three main chronological stages in gynecology ‒ menarche, reproductive stage and menopause/postmenopause - are possibly impacted by vitamin D deficiency. A large amount of emerging data show that vitamin D is a confounding factor in these parameters. Gynecology stays at the crossroads with endocrinology and, in the light of the rising knowledge about the involvement of vitamin D in many gynecological disorders, it is worth to investigate the exact role of vitamin D in this area.

Potential of biochar use in building materials.

A critical review of the articles dealing with biochar in terms of the reuse of biomass waste in building materials and its impact on material properties was conducted using five different electronic databases; thirteen articles were selected for this critical review. Biochar was used as a replacement for cement and aggregate in cementitious composites and as an addition in wood polypropylene composites and plasters. The biochar dosages ranged from 0.

Prevalence of mobile device-related lower extremity discomfort: a systematic review.

Mobile device users often experience musculoskeletal discomfort due to the intensive use of these devices in static body postures. Prolonged sitting and standing at work and in free time are risk factors for various diseases and all-cause mortality. Prolonged static postures are the main cause of lower extremity discomfort.

Prevalence of mobile device-related musculoskeletal pain among working university students: a cross-sectional study.

The aim of the present study was to investigate usage patterns of mobile devices and their impact on users' musculoskeletal system among working university students in Slovenia at the Faculty of Chemistry and Chemical Technology of the University of Ljubljana. An Internet-based survey was sent to students' e-mail addresses and students provided information about usage patterns and reported on musculoskeletal pain (MSP) that may relate to mobile device usage in the past 12 months. A total of 535 students (63% females and 37% males) aged 18 years or older completed the survey and fulfilled the inclusion criteria.
