Vitamin D Deficiency-A Public Health Issue in Children.

Background: 25-hydroxyvitamin D [25(OH)D] deficiency is a global health concern, particularly in pediatric populations, with implications for musculoskeletal health and overall well-being. This study aimed to evaluate serum 25(OH)D levels in a pediatric population and assess the prevalence of deficiency and insufficiency.

Methods: A retrospective analysis was conducted on data from 741 pediatric patients (2-17 years old) who visited an urban hospital for children for acute respiratory and gastrointestinal conditions in the span of 2 years.

Analysis of PEM Water Electrolyzer Failure Due to Induced Hydrogen Crossover in Catalyst-Coated PFSA Membranes.

Polymer electrolyte membrane water electrolysis (PEMWE) is a leading candidate for the development of a sustainable hydrogen infrastructure. The heart of a PEMWE cell is represented by the membrane electrode assembly (MEA), which consists of a polymer electrolyte membrane (PEM) with catalyst layers (CLs), flow fields, and bipolar plates (BPPs). The weakest component of the system is the PEM, as it is prone to chemical and mechanical degradation.

The Role and Involvement of Stem Cells in Periodontology.

Periodontitis is a widespread inflammatory condition, characterized by a progressive deterioration of the supporting structures of the teeth. Due to the complexity of periodontal tissue and the surrounding inflammatory microenvironment, the repair of lesions at this level represents a continuous challenge. The regeneration of periodontal tissues is considered a promising strategy.

Contextualising planned behaviours to the vaccination against COVID-19 in the European Union.

The article targets the reasons that are behind behaviour orientation in the vaccination process against COVID-19. The data we are using come from the Flash Eurobarometer 494, collected in May 2021. The key dependent variable puts together vaccination intentions (soon, later on in 2021, undecided, later, never) and the fact of being vaccinated or not.

The Optimal Management of Infections.

is one of the most frequent etiologic agents of STDs (sexually transmitted diseases). Untreated asymptomatic gonococcal infection in women can lead to spreading of the infection in the sexually active population and could lead to late consequences, such as sterility or ectopic pregnancies. One important issue about is its increasing resistance to antibiotics.
