University students have been identified as a particularly vulnerable group for adverse mental health outcomes owing to the distinctive implications of the COVID-19 prevention measures on the educational sector. Even prior to the pandemic, university students were identified as being at increased risk for adverse mental health outcomes and suicidality. Although various factors can enhance the risk of suicide, one of the strongest predictors of suicidality is the presence of depressive symptomology. The current stud [...]

Lung transplant (LTx) survival and quality of life have been steadily improving, partially from changes in candidate selection for transplantation. There are well-known high-risk factors that lead to poor LTx outcomes, which may be referred to as ‘accounted’ risks. However, there are also other ‘unaccounted’ risks that are not included in the existing model for expected LTx survival to help programs for resource allocation. We performed a retrospective cohort study of all LTx recipients over the age of 18 at UC San [...]

The paper analyses the performance of a spherical solar collector compared to the efficiency of a flat-plate solar collector, which is the type of solar collector that does not use a tracking system in collecting solar radiation for energy conversion. Spherical solar collector benefits from a constant value of the angle of incidence, which optimizes the solar radiation that strikes the absorber of the solar device and maximizes the energy collection. Besides, the spherical geometry has a larger area for equal dimen [...]

Careful selection of lung transplant (LT) recipients with cystic fibrosis (CF) may improve outcomes; therefore, we studied the impact of sex and age at the time of LT on long-term survival of patients with CF. LT recipients with CF who received post-LT care at our center between July 1, 2007 and April 30, 2021 were included. The primary outcome was death or retransplantation. Cox proportional hazard analysis and the Kaplan-Meier method were used. Of 59 included LT recipients, the median age at first LT was 28 (22, [...]

Bioaugmentation by Pseudomonas strains is widely used for the removal of pollutants in wastewater. In this study, we aimed to determine the removal of pentachlorophenol (PCP, 800 mg·L–1) in secondary wastewater by the bioaugmentation process. We determined the effects of using three surfactants, namely sodium dodecyl sulfate (SDS), cetyl-tri-methyl-ammonium bromide (CTAB), and Tween 80 for PCP removal. We determined the effect of the role of PCP surfactant for the biofilm and auxin production of the se [...]

This study aims to determine if high-voltage PRF could effectively adjunct epidural adhesiolysis (EA) in treating patients with chronic lumbosacral radiating pain (LSRP) and neuropathic characteristics. A total of 409 patients suffering from a single leg-radiating pain lasting for > six months and unresponsive to previous treatments were divided into three different groups: Group 1 consisted of 227 patients suffering from LSRP in lumbar stenosis, 84 treated with EA alone and 143 with PRF-EA; group 2 consisted of [...]

With the progressive rise in rates of liver transplantation, stagnant donor pool, and social factors, living donor liver transplantation (LDLT) forms the majority of liver transplantations performed in Asian countries. As the global prevalence of metabolic-associated fatty liver disease (MAFLD) is increasing, around 17-25% of all the prospective donors turn out to be steatotic at the time of evaluation and, as such, rejected for donor hepatectomy, thereby considerably reducing the living donor pool. Steatotic graft [...]

The COVID-19 pandemic caused abrupt changes in daily routines, social connections, and ways of life. It is yet unknown the full impacts these extended changes have had on the long-term mental well-being of those who shared this global experience. As a contribution to our overall understanding of this phenomena, this study explored the effects of the COVID-19 pandemic on the mental well-being of older adults in the Southern United States. Secondary data analyses were performed using the COVID-19 Emotional Impact Sur [...]
