Understanding the trend of student authorship is crucial in determining its correlation to scholarly impact for corresponding authors. Our objective is to investigate student authorship rates over time in articles published in JAMA Internal Medicine (IM), as well as to examine potential effects student authors have on scholarly impact scores of corresponding authors via H-index measures.

Authorship data including student authors (SA), first student authors, and corresponding authors (CA) from prior JAMA IM publications between 2010 and 2018 were collected, with a total of 701 studies. Analysis of variance (ANOVA) and independent sample

tests were performed to assess for differences in the mean by publishing year and student authorship, respectively.

Of 4591 total authors, 683 (14.9%) were considered student authors. The percentage of student authorship increased from 46.3% to 58.0% between 2010 and 2018, respectively. No difference in average H-indices of CA between SA and non-SA groups (overall NSA H

mean 30.2, vs SA H

mean 32.1, p=0.371) was noted.

Student participation in research is not a disadvantage to scholarly impact for corresponding authors. Increased student authorship reflects a promising trend towards greater student participation in research within the field of medicine.

Although ophthalmic complaints are not presently considered a classic symptom of ALS, retinal changes such as thinning, axonal degeneration and inclusion bodies have been found in many patients. Retinal abnormalities observed in postmortem human tissues and animal models are similar to spinal cord changes in ALS. These findings are not dramatically unexpected because retina shares an ontogenetic relationship with the brain, and many genes are associated both with neurodegeneration and retinal diseases. Experimental studies have demonstrated that ALS affects many "vulnerable points" of the retina. Aggregate deposition, impaired nuclear protein import, endoplasmic reticulum stress, glutamate excitotoxicity, vascular regression, and mitochondrial dysfunction are factors suspected as being the main cause of motor neuron damage in ALS. Herein, we show that all of these pathways can affect retinal cells in the same way as motor neurons. Furthermore, we suppose that understanding the patterns of neuro-ophthalmic interaction in ALS can help in the diagnosis and treatment of this disease.

Deriving health utilities for rare medical conditions such as aromatic L-amino acid decarboxylase (AADC) deficiency poses challenges. The rarity of AADC deficiency and the fact that this genetic condition often presents in very young children means that robust utility values cannot be derived from the child or their parent/caregiver. Alternative approaches, eg, discrete choice experiments (DCE), are required in order to provide health utilities. The aim of the study was to generate health utilities for AADC deficiency using a DCE.

The DCE was completed online by panel participants from a UK representative sample. The DCE comprised 6 AADC deficiency attributes (2-6 levels) mobility, muscle weakness, oculogyric crises, feeding ability, cognitive impairment and screaming. These were identified from published literature, clinician input, parent interviews and expert opinion. Participants were presented with 10 choice sets specified using an orthogonal design, including a repeat task to evaluate choice consistities were derived for AADC deficiency through a DCE. These will be used for a cost-effectiveness model of an AADC deficiency treatment.

Sleep disturbance is a paramount public health concern that besets many modern middle-aged and elderly community residents. Reading is important to adults as it facilitates the completion of daily tasks, and might be associated with sleep issues. The present study aimed to analyze the association between reading and sleep using Chinese national survey data.

The 2018 China Family Panel Studies survey data were used, and the target sample was extracted according to age (>40 years). Reading behavior and reading quantity were chosen as independent variables, and sleep duration, sleep-onset time, and sleep quality were selected as dependent variables. A multilevel mixed linear/ordinal logistic regression model was employed to evaluate the association, and restricted cubic splines with 4 knots were employed to flexibly model the association of reading quantity and sleep duration.

A total of 18,740 adults were selected, and the reading rate was 15.04%. Reading habit was significantly negatively associated with weekday sleep duration, but not with duration at weekends, as determined from the full set of confounders adjusted models. Reading behavior was also associated with delayed sleep-onset time (OR 0.935, 95% CI 0.908-0.964), but not with sleep quality. Reading quantity showed a nonlinear relationship with sleep duration, appropriate reading quantity was related with long sleep duration.

Reading was associated with short sleep duration on weekdays, but not with sleep quality. Furthermore, reading was related to late sleep-onset time, and for the middle-aged and elderly Chinese populations, appropriate reading quantity was related with long sleep duration.

Independently diverting to an opt-out system confers no obvious advantage and can harm efforts to bolster donations. Rather, it is essential to address barriers to organ donation on several levels along with a switch in system. Moreover, for many countries, it may be more beneficial to adequately capacitate the donation system already in place, rather than entertain a significant change with its attendant resource requirements. For decades, the international transplant community has been involved in vigorous debate as to the merits of moving from default opt-in systems to opt-out policies to grow organ donor numbers and better meet the ever-increasing demand for lifesaving transplants. Opt-out is certainly en vogue, with Wales, England and Nova Scotia recently switching over, Scotland due to become opt-out in March 2021 and Northern Ireland and Canada seriously considering a similar move. Thanks to several countries making the switch from opt-in to opt-out over the last 20-30 years, there are sets of robust longitudinal data that aid in analysing the efficacy of donation systems. However, these data are often contradictory and largely inconclusive, suggesting other factors may be in play. This paper reviews some emerging trends in opt-in versus opt-out organ donation policies and considers recent data that elucidates some of the main contentions across each. Ethical frameworks underpinning donation systems, such as informed consent, trust and transparency, are discussed in detail. Substantial time is also devoted to opt-in vs opt-out systems in developing countries, which tend to be excluded from many analyses, and where the challenges faced are magnified by socio-economic constraints. This constitutes a major gap in recently published literature, as developing countries often lag far behind their developed counterparts in donor and transplant numbers.

Cardiovascular disease (CVD) is a major cause of death and disability among people with diabetes in the world and it is proving to be a major barrier to sustainable human development. Despite CVD continuing to devastate human survival, few studies in Ethiopia have focused on its prevalence which alone are insufficient to assess the risk of incident cardiovascular events. Therefore, we determined the incidence and predictors of cardiovascular disease among diabetic patients in a selected tertiary healthcare setting of Ethiopia.

A retrospective cohort study using secondary data was conducted on 399 randomly selected diabetes patients. Data were entered using Epi-Data and analyzed using Stata version 14. Multivariable Weibull proportional hazards regression analysis was used to identify the predictors of CVDs (namely, coronary heart disease (CHD), stroke, and peripheral arterial disease (PAD)) at 5% level of significance.

After a median follow-up of 5.9 years, the overall incidence rate of CVD per 100 persese findings emphasize the need of attention for CVD patients with CKD and hypertension (HTN) comorbidities and a longer follow-up period using a prospective study design to determine the long-term effects of predictors of CVD among diabetic patients.

Emerging issues of occupational safety and health (OSH) in floating solar photovoltaic projects (FSPV) have rarely been addressed to achieve the Sustainable Development Goals (SDGs). The current scoping review has been planned to demonstrate OSH issues experienced by the workers engaged in the installation and maintenance of FSPV projects and existing ergonomics design interventions in the solar photovoltaic industry with a focus on the FSPV sector.

A literature review was conducted from four major electronic databases (Science Direct, Google Scholar, Web of Science, and Scopus) using predefined keywords and following the PRISMA framework for the period 1965-2020. A total of 49 studies under five headings, namely a) overview of key reasons for the emergence of floating solar photovoltaic projects, b) occupational risks of workers engaged in the solar PV industry/FSPV sector, c) occupational risks in workplaces/occupations similar to floating solar photovoltaics projects, d) availability of training moduleght the contextual risk factors in the emerging FSPV sector and the need for addressing them through ergonomics design interventions for successfully achieving the Sustainable Development Goals.Extemporaneous compounding is among the key hospital pharmacy services that promotes pharmaceutical care. It is a long-standing practice in dermatology for patients who need custom-made drug products. The practice of dermatologic compounding practice in Ethiopian public hospitals is found at the beginning and very few hospitals have started the practice so far. This research communication aimed at examining Ethiopian public hospitals' extemporaneous compounding practice for dermatologicals with emphasis on regulatory requirement and quality control activities. read more To benefit patients from these products, good compounding practice should be obeyed in line with the expansion of the service. Gaps have been observed in the facilities with regard to quality assurance system and compliance with the country's regulatory requirements. This implies a need to take appropriate and timely actions by the responsible stakeholders and expand the service in the country by fulfilling the regulatory requirement.
