Echinococcosis: An Uncommon Cause of Thoracic Pain.

Echinococcosis is caused by larvae, the metacestode stage of the tapeworm , and poses a public health issue in many developing countries. It generally affects a single organ, most commonly the liver or lungs, and rarely involves multiple organs. We present the case of a 24-year-old Indian man living in Portugal, who was admitted to the Emergency Department with left-sided thoracic pain radiating to the back.

The Effects of the Nocturnal Sleep on Learning of a Complex Motor Skill in Young and Older Adults.

Background/study Context: Research on older adults has shown impairments in nocturnal sleep, impacting motor memory consolidation and learning. However, previous studies primarily focus on simple tasks, limiting generalization to complex motor activities. Moreover, no evidence exists on how sleep influences adaptability and relearning in older adults.

A review on the biological activities and the nutraceutical potential of chitooligosaccharides.

Chitooligosaccharides (CHOS) or chitosan oligosaccharides (COS) are oligomers mainly composed of d-glucosamine (GlcN) units and structured in a positively charged, basic, amino molecule obtained from the degradation of chitin/chitosan through physical, chemical, or enzymatic methods. CHOS display physicochemical properties attractive to applications from the food to the biomedical field, such as non-toxicity to humans, high water solubility, low viscosity, biocompatibility, and biodegradability. These properties also allow CHOS to exert important biological activities, for example, antioxidant, antimicrobial, anti-inflammatory, immunomodulatory, antitumor, and hypocholesterolemic ones, besides to exhibit applications in food systems, technological, and nutraceutical potential.

Optical performance analysis of a hybrid parabolic trough collector with photovoltaic slats.

Small-sized parabolic trough collectors are a promising solution for renewable heat supply, meeting the industrial demand for thermal energy up to 250°. In this manuscript, a novel, to our knowledge, optical design hybridizing parabolic trough concentrators with photovoltaic generators is introduced, incorporating actionable photovoltaic slats in the aperture plane. This configuration allows efficient operation under diffuse irradiance and improves electricity production when direct irradiation is insufficient.

Exploring the role of health applications in promoting health among older adults: a scoping review protocol.

Introduction: Evidence on the use of health apps to support healthcare and promote the health of individuals aged 55 and older is limited. Older adults face challenges with literacy, usability and accessibility of digital tools. This scoping review aims to explore how digital health apps promote healthy living and self-empowerment while identifying successful applications for older adults METHODS AND ANALYSIS: This study will adopt the JBI methodology for scoping reviews, guided by the (Population, Concept, Context) framework.
