Pathogenic bacteria, viruses, and parasites can cause waterborne disease outbreaks. The study of coastal water quality contributes to identifying potential risks to human health and to improving water management practices. The Río de la Plata River, a wide estuary in South America, is used for recreational activities, as a water source for consumption and as a site for sewage discharges. In the present study, as the first step of a quantitative microbial risk assessment of the coastal water quality of this river, a descriptive study was performed to identify the microbial pathogens prevalent in its waters and in the sewage discharged into the river. Two sites, representing two different potential risk scenarios, were chosen: a heavily polluted beach and an apparently safe beach. Conductivity and fecal contamination indicators including enterococci, Escherichia coli, F + RNA bacteriophages, and human polyomaviruses showed high levels. Regarding enterococci, differences between sites were significant (p-values <0.001). 93.3% and 56.5% of the apparently safe beach exceeded the recreational water limits for E. coli and enterococci. Regarding pathogens, diarrheagenic E. coli, Salmonella, and noroviruses were detected with different frequencies between sites. The parasites Cryptosporidium spp. and Giardia duodenalis were frequently detected in both sites. The results regarding viral, bacterial, and parasitic pathogens, even without correlation with conventional indicators, showed the importance of monitoring a variety of microorganisms to determine water quality more reliably and accurately, and to facilitate further studies of health risk assessment. The taxonomic description of microbial pathogens in river waters allow identifying the microorganisms that infect the population living on its shores but also pathogens not previously reported by the clinical surveillance system.

Introduction And Aims: Neutrophil percentage-to-albumin ratio (NPAR) is a novel biomarker of systemic inflammation. The aim of this study was to explore the relationship between NPAR and periodontitis.
Methods: Data from the National Health and Nutritional Examination Survey (NHANES) between 2009 and 2014 (N = 10,128) were utilized in this cross-sectional study.

Background: Exergames are interactive technology-based exercise programs. By combining physical and cognitive training components, they aim to preserve independence in older adults and reduce their risk of falling. This study explored whether primary end users (PEU, healthy older adults and patients with neurological and geriatric diagnoses) and secondary end users (SEU, health professionals) evaluated the ExerG functional model to be usable, providing a positive experience and therefore acceptable.

Background/objectives: A globally aging population necessitates public health action that supports healthy aging. Although it is well established that participation in physical activity (PA), sport, and active recreation are important for healthy aging, PA levels remain generally lower among older adults. This study examines trends in physical activities that older adults engage in and identifies disparities in activities across subgroups as defined by age, gender, and socioeconomic status.

Exposure to nature is associated with better mental health in the general population, but prior evidence suggests that people living with severe, chronic mobility impairment from paralysis due to spinal cord injury (SCI) may not experience similar benefits. Since many people living with SCI use wheelchairs and other medical devices for mobility, further exploration of how people living with mobility disability experience greenspace is needed to achieve equity in access to all public places. We assessed experiences with accessing greenspace reported in a sample of people living with chronic SCI and the meanings they ascribe to these experiences for their health and quality of life.

Background: The use of video games in rehabilitation settings is gaining increasing popularity. However, the lack of commercial video games suitable for children with disabilities and the disappointing user experience of serious games limit their applicability. The aim of this study was to assess the usability, acceptability and user experience of GiocAbile, an active video game for children with cerebral palsy (CP).
