Fundamental data analysis assists in the evaluation of critical questions to discern essential facts and elicit formerly invisible evidence. In this article, we provide clarity into a subtle phenomenon observed in cancer incidences throughout the time of the COVID-19 pandemic. We analyzed the cancer incidence data from the American Cancer Society [1].

Background: Intergenerational friendship, a mechanism of social support, is an effective intervention to reduce the increasing risk of social isolation (SI) and develop companionship in the older adult population. The COVID-19 pandemic provided a unique opportunity to examine the psychosocial intervention of befriending via technology use as a primary form of contactless socialization.

Objective: The study aims to explore the effectiveness of the befriending intervention through a contactless, intergenerational service-learning project on older adult emotions, especially boredom and loneliness as the key attributes of SI, and on students' attitude toward companionship.

Mycoremediation uses mushroom forming fungi for remediation of sites contaminated with biotic and abiotic contaminants. The root-like hyphae of many fungi, the mycelia, have been used to remediate soil and water. In this study mushroom mycelia biofilters were evaluated for remediation efficacy of wetland water polluted with crow feces containing antibiotic resistant (AMR) bacteria.

Introduction: The competent healing touch of a caregiver is a critical component to the care patients receive. The more skilled the provider, the higher the likelihood outcomes will be delivered in a safe and effective manner. Unfortunately, in recent years, hospitals in the United States have faced immense financial pressures that are threatening their economic sustainability and patients' access to care in the future.

Socially engaged older adults are less likely to decline in health and happiness and have a higher quality of life. Building upon this premise, examination was conducted on the domains of social determinants of health, specifically the social and community context per Healthy People 2030 objectives. These mechanisms of social interaction, in the form of group activities, community engagement, and virtual interactions via email or text message, were assessed using hierarchical regression analysis to find out their association with wellbeing, depression symptoms, and cognition of older adults.

This systematic review emphasizes the need for technology use in older adults to reduce social isolation. With the advancement of technology over the years, the effectiveness of interventions based on its use can be examined to see how these can address the problem of social isolation and enhance social wellbeing. We focus on identifying how older adults can most benefit from affordable and accessible technology use and how the training and implementation of such interventions can be tailored to maximize their beneficial effect.

Aim: The study examined the hypothesis that crow-borne Campylobacter can function as environmental reservoirs and indicators of antibiotic resistance (AR) determinants circulating in a human population.

Methods And Results: Two species of crows from Washington (WA), United States, and Kolkata, India, respectively, were examined for their ability to carry antibiotic resistant Campylobacter. Campylobacter jejuni was the only species isolated by selective agar plating from crow faecal samples.

The study examines whether crows are carriers of extraintestinal pathogenic (ExPEC) and avian pathogenic (APEC)-like strains, and if wetland roost areas contribute to their spread. A total of 10 crow feces ( = 71) and 15 water isolates ( = 134) from a wetland area could be characterized as potentially ExPEC based on the presence of ≥2 of the five cardinal genes and while six fecal and 14 water isolates could be characterized as potentially APEC-like based on the presence of plasmid associated genes: , episomal and . A total of 32 fecal and 27 water isolates tested carried plasmids based on incompatibility typing.

Iran will encounter rapid population aging, resulting from increased life expectancy and fluctuating fertility rates during its eight-year war with Iraq (1980-1988). The need for long-term care in Iran is expected to increase dramatically. The purpose of this paper is to examine Iran's health care system and informal care upon discussing its demographic profile.

Information on the dissemination of antibiotic resistance mechanisms in the environment as well as wild life is needed in North America. A constructed wetland (where ∼15,000 American crows roost) was sampled on the University of Washington Bothell Campus for the presence of antibiotic resistant (ARE). Crow droppings from individual birds and grab samples of water were collected in 2014-2015.

spp. are major causes of gastroenteritis worldwide. The virulence potential of shed in crow feces obtained from a roost area in Bothell, Washington, was studied and compared with that from isolates from other parts of Washington and from a different crow species 7,000 miles away in Kolkata, India.

The goal of this study was to gain insight into the diversity of culturable actinobacteria in desert soil crusts and to determine the physiological characteristics of the predominant actinobacterial group in these crusts. Culture-dependent method was employed to obtain actinobacterial strains from desert soil samples collected from Shapotou National Desert Ecological Reserve (NDER) located in Tengger Desert, China. A total of 376 actinobacterial strains were isolated and 16S rRNA gene sequences analysis indicated that these isolates belonged to 29 genera within 18 families, among which the members of the family Geodermatophilaceae were predominant.

The effect of low doses of free chlorine on the detection of Helicobacter pylori (H. pylori) cells by qPCR in tap water was monitored. Detection of sequences targeted to the ureA gene from preparations containing 107 cells/ml decreased about 2-4 logs by days 9 and 14, respectively.

A genetic characterization of eight virulence factor genes, elastase, lipase, polar flagella (flaA/flaB, flaG), lateral flagella (lafA), and the enterotoxins alt, act, and ast, was performed using polymerase chain reaction with 55 drinking water and nine clinical isolates. When 16 Aeromonas hydrophila strains, seven Aeromonas veronii strains, and seven Aeromonas caviae strains exhibiting different combinations of virulence factor genes were tested in immunocompromised mice by intraperitoneal injection, only those strains that had one or more of the enterotoxins flaA, flaB, and either flaG or lafA showed signs of being virulent. The correlation was seen in 97% (29/30) of the strains, which included strains from drinking water.

Existing biochemical methods cannot distinguish among some species of Aeromonads, while genetic methods are labor intensive. In this study, primers were developed to three genes of Aeromonas: lipase, elastase, and DNA gyraseB. In addition, six previously described primer sets, five corresponding to species-specific signature regions of the 16S rRNA gene from A.
