Historically and for ease of classification, the geriatric patient has received a chronologic definition of a person 65 years and older. Chronologic age remains an independent risk of postoperative complications and adverse surgical outcomes. Frailty is an expression of an individual's biological age and as such a more reliable determination of their vulnerabilities or resilience to stress.

Non-centrifugal raw cane sugar (NRCS) is a minimally processed product from sugarcane (Saccharum officinarum L). This product contains phytochemical and nutritional compounds that benefit human health. Despite these advantages, NRCS commercialization is hindered by a lack of knowledge about its composition and, consequently, the absence of quality standards.

The dynamic and continuously evolving field of ophthalmology necessitates rigorous regulatory oversight in the United States. This review outlines the multifaceted Food and Drug Administration's (FDA) approval process for ophthalmic products, detailing the classifications, pathways, and regulatory compliance for devices, drugs, biologics, and combination products. Particular emphasis is placed on distinct frameworks for Class I, II, and III devices, as well as regulations for drugs, biologics, and combination products.

Article Synopsis
  • Sugarcane is crucial for global agriculture, but its growth is challenged in acidic soils high in aluminum (Al), which can hinder crop development; studying its responses to Al stress can help enhance productivity in such conditions.
  • Various Brazilian sugarcane cultivars were tested for their physiological responses, nutrient contents, and gene expression related to Al stress, revealing significant differences among them.
  • The RB867515 cultivar was the most tolerant to Al stress, maintaining nutrient levels and showing key gene expressions for resilience, while RB928064 and RB935744 exhibited lower tolerance, providing insights for breeding Al-tolerant sugarcane varieties.

Soil solid-solution distribution coefficients (K) are used in predictive environmental models to assess public health risks. This study was undertaken to determine K for potentially toxic elements (PTE) Cd, Co, Cr, Cu, Ni, Pb, and Zn in topsoil samples (0-20 cm) from 30 soils in the State of São Paulo, southeastern Brazil. Batch sorption experiments were carried out, and PTE concentrations in the equilibrium solution were determined by High Resolution Inductively Coupled Plasma Mass Spectrometry (HR-ICPMS).

Biodegradable films are a promising strategy to reduce the environmental impact caused by conventional plastics commonly used in agriculture. This study focused on the production and characterization of Konjac glucomannan (KGM) and alginate (ALG) based films enriched with sugarcane vinasse (VIN), a nutrient-rich wastewater generated in large volumes by the sugar-ethanol producing industries. ALG, KGM and ALG/KGM blended (50:50) films were produced by casting and treated with calcium ions (Ca) (ALG films) and a combination of Ca, alkali, and ethanol (KGM and ALG/KGM films).

This study evaluated the physicochemical and morphological properties of pectin and chitosan particles combined with sugarcane vinasse for soil fertilization applications. Particles were obtained by adding the biopolymeric solutions (pectin or chitosan solution) dropwise into the crosslinking solutions (calcium chloride 1% in ethanolic solution or tripolyphosphate 5% aqueous solution) followed by drying. Vinasse enhanced pectin gel stability improving pectin/vinasse particle properties.

Unlabelled: A paucity of research exists on medical student pressure ulcer education.

Purpose: This study examines medical student competency outcomes following implementation of a competency-based curriculum that included a pressure ulcer component in its educational intervention.

Methods: Over a 5-year period, 645 medical students completed the curriculum, which included a preceptor-led didactic session, online study resources, clinical experiences, and a brief online competency assessment.

High methoxyl pectin was used as biopolymeric matrix to produce a novel slow release soil fertilizer added with sugarcane vinasse and lipid extracted microalgal (Desmodesmus subspicatus) biomass residue (LMBR). Vinasse acted as the biopolymer solvent, providing greater stability to pectin gel, and as a source of nitrogen (N), potassium (K), calcium (Ca) and magnesium (Mg). LMBR (0.

Quality reference values (QRV) for potentially toxic elements (PTE) in soils are established as a tool for prevention and monitoring of soil pollution. These values should be periodically revised in order to ensure soil safety for agricultural purposes. Brazil is market leader for several commodities; therefore, the safety of Brazilian soils is of worldwide strategic importance.

Background: The addition of functional electrical stimulation (FES) to treadmill gait training with partial body weight support (BWS) has been proposed as a strategy to facilitate gait training in people with hemiparesis. However, there is a lack of studies that evaluate the effectiveness of FES addition on ground level gait training with BWS, which is the most common locomotion surface.

Objective: To investigate the additional effects of commum peroneal nerve FES combined with gait training and BWS on ground level, on spatial-temporal gait parameters, segmental angles, and motor function.
