Sorghum-based beverages were developed and the effects of decortication on nutritional composition and biofunctional properties after a simulated gastrointestinal digestion were analyzed. For that, white sorghum flours from whole (WS) and decorticated (DS) grains were obtained and used to prepare sorghum beverages. They were analyzed regarding chemical composition, minerals, and phenolic acid contents. Moreover, the bioaccessibility of phenolics, proteins, and the potential bioactivity (ABTS+ scavenging, ACE-I inhi [...]

Malnutrition is a problem that is often not identified in hospitals as 8% of hospital patients are diagnosed but malnutrition is estimated to affect 20-50% of patients. Federal programs such as Joint Commission accreditation and the new, optional, global malnutrition composite score from CMS may improve inpatient malnutrition diagnosis, but there may be an opportunity to do more from a regulatory side. It’s unknown how many states are considering malnutrition from this standpoint. The study’s goal was t [...]

The environmental impact of emissions appears to be increasingly important for food, particularly those of animal origin. The LCA (Life-Cycle Assessment) method, an internationally standardized method used to calculate the environmental impact of goods or services, in the carbon footprint, does not take into account the carbon set and consequently the subtraction of carbon dioxide by the plant biomass whether or not aimed at the production of food of animal origin. This methodology could overestimate the carbon dio [...]

The geriatric population is increasing all over the world. Aging people have special health requirements and comprehensive medical checkups prevent physical, functional and mental decline during the aging period. This study aimed to examine the fitness level and identify problems with the well-being of elderly persons. In this context, the study also attempted to determine the relationship between socio-demographic factors and the health status of elderly adults. In this cross-sectional study, 168 elderly adults (≥ [...]

Burnout is a syndrome commonly characterized by the three dimensions of Maslach and Leiter's model, namely emotional exhaustion, depersonalization, and lack of professional accomplishment. While burnout affects individuals in all professions, teachers are recognized as being at particular risk, a fact explained in the literature by the high level of relational demands inherent to the profession. During the pandemic and subsequently, these demands have even increased. Several studies have focused on the influence of [...]

People diagnosed with dementia are experts on living with the disease, yet their perspectives are often overlooked in research and practice. The pandemic has amplified health inequities among older adults, but the impact of the pandemic on the lived experience of people living with dementia remains unclear. This qualitative study used a series of 2 virtual focus groups with people living with dementia (N = 7) to explore challenging situations and emotions experienced by community-dwelling people living with dementi [...]

In the oil distillate fraction alkylation process, a modified Zr zeolite ZSM-5 was obtained and studied. The modification was executed using a method that impregnated ZSM-5 with a 5% solution of ZrOCl2∙6H2O. X-ray diffraction studies were conducted on zeolite ZSM-5, zirconyl chloride modifier ZrOCl2∙6H2O, and modified zeolite ZSM-5-ZrO2, which was calcined at temperatures of 200, 400, and 550°C. The results revealed that the phase composition of modified ZSM-5-ZrO2 zeolite samples varied depending on the calcinatio [...]

Carnauba straw (Copernicia prunifera), residual biomass derived from wax extraction, was evaluated as a potential feedstock for bioenergy production. The characterization was carried out using elemental analysis, proximate analysis, Higher Heating Value (HHV), FTIR spectroscopy, SEM, and FRX. The carbonization, using a Muffle Furnace, was applied as a thermal conversion technique to improve the fixed carbon content, and preliminary densification was done to assess the potential for future production of briquettes.

The COVID-19 pandemic and its associated disruptions have significantly impacted university students’ lives worldwide. The COVID Stress Scale (CSS) is a 36-item self-reporting instrument designed to measure stress caused by the COVID-19 pandemic. This study purposed to examine the psychometric properties of the Korean version of the CSS for use with Korean university students. The study sample comprised 402 undergraduate students enrolled in a four-year private university in central South Korea. This cross-sectiona [...]
