ObjectiveFrailty increases poor clinical outcomes in older adults, the aim of this study was to investigate the prevalence and factors associated with frailty and pre-frailty in older adults in China.Research design and methodsData were obtained from the Sample Survey of the Aged Population in Urban and Rural China in 2015, which was a cross-sectional study involving a nationally representative sample of older adults aged 60 years or older from 31 provinces/autonomous regions/municipalities in mainland China. The frailty index (FI) based on 33 potential deficits was used to classify individuals as robust (FI &lt; 0.12), pre-frail (FI ≧0.12 and &lt;0.25) and frail (FI ≥0.25).ResultsA total of 208,386 older people were included in the study, and the age-sex standardised prevalence of frailty and pre-frailty among older adults in China was 9.5% (95% CI 9.4–9.7) and 46.1% (45.9–46.3) respectively. The prevalence of frailty and pre-frailty was higher in female than in male older adults, higher in rural than in urban older adults, and higher in northern China than in southern China. The multinomial analysis revealed similar risk factors for frailty and pre-frailty, including increased age, being female, living in a rural area, low educational attainment, poor marital status, living alone, difficult financial status, poor access to medical reimbursement, and living in northern China.ConclusionFrailty and pre-frailty are very common among older adults in China and differ significantly between southern and northern China, men and women, and rural and urban areas. Appropriate public health prevention strategies should be developed based on identified risk factors in frail and pre-frail populations. The management of frailty and pre-frailty should be optimised according to regional and gender differences in prevalence and associated factors, such as strengthening the integrated management of chronic diseases, increasing reimbursement rates for medical costs, and focusing on vulnerable groups such as the disabled, economically disadvantaged, living alone and those with low literacy levels, in order to reduce the burden of frailty among older adults in China.

BackgroundPreventing infection in healthcare workers (HCWs) is crucial for protecting healthcare systems during the COVID-19 pandemic. Here, we investigated the seroepidemiology of SARS-CoV-2 in HCWs in Norway with low-transmission settings.MethodsFrom March 2020, we recruited HCWs at four medical centres. We determined infection by SARS-CoV-2 RT-PCR and serological testing and evaluated the association between infection and exposure variables, comparing our findings with global data in a meta-analysis. Anti-spike IgG antibodies were measured after infection and/or vaccination in a longitudinal cohort until June 2021.ResultsWe identified a prevalence of 10.5% (95% confidence interval, CI: 8.8–12.3) in 2020 and an incidence rate of 15.0 cases per 100 person-years (95% CI: 12.5–17.8) among 1,214 HCWs with 848 person-years of follow-up time. Following infection, HCWs (n = 63) mounted durable anti-spike IgG antibodies with a half-life of 4.3 months since their seropositivity. HCWs infected with SARS-CoV-2 in 2020 (n = 46) had higher anti-spike IgG titres than naive HCWs (n = 186) throughout the 5 months after vaccination with BNT162b2 and/or ChAdOx1-S COVID-19 vaccines in 2021. In a meta-analysis including 20 studies, the odds ratio (OR) for SARS-CoV-2 seropositivity was significantly higher with household contact (OR 12.6; 95% CI: 4.5–35.1) and occupational exposure (OR 2.2; 95% CI: 1.4–3.2).ConclusionWe found high and modest risks of SARS-CoV-2 infection with household and occupational exposure, respectively, in HCWs, suggesting the need to strengthen infection prevention strategies within households and medical centres. Infection generated long-lasting antibodies in most HCWs; therefore, we support delaying COVID-19 vaccination in primed HCWs, prioritising the non-infected high-risk HCWs amid vaccine shortage.

Based on the circular letter of the Ministry of Education and Culture (Kemendikbud) Directorate of Higher Education No. 1 year 2020 during the covid-19 pandemic, universities eliminated teaching and learning activities on campus and shifted them to distance learning (online). In online learning at the Faculty of Health Sciences As-Syafi'iyah Islamic University the implementation of online lectures raises several obstacles such as the internet network and assignments that become stressors for students. The purpose of the study was to determine the relationship between online learning and the incidence of stress in students at the Faculty of Health Sciences, As-Syafi'iyah Islamic University during the Covid-19 pandemic. The research method used descriptive correlation with a cross sectional approach, a population of 184 students consisting of semesters 2, 4, and 6. The sample uses the slovin formula to 65 students taken by proportional sampling technique. The analysis used univariate and biavariate using Chi-Square test = 5% (0.05). The results of the univariate analysis (%) showed a good picture of online learning 55.4% and the incidence of stress was 43.1%, bivariate analysis obtained p or Asym values. Sig. (2-sided) = 0.209 with a value of = 5% (0.05). The conclusion is that there is no relationship between online learning and the incidence of stress in students at the Faculty of Health Sciences, As-Syafi'iyah Islamic University during the Covid-19 pandemic. Suggestions are that students are expected to be more active in class forums such as asking about material that has not been understood and activating the zoom camera.

Spectrum and Antibiotic Resistance in the Community and Hospital-Acquired Urinary Tract Infected Adults
Authors: Abu Taha Adham 
Published: July 2023

Background: Urinary tract infection (UTI) is the most common infection in the community. The causative agents and antibiotic resistance differ between community-acquired and hospital-acquired urinary tract infections.
Objectives: This study aimed at identifying the etiologic agents in both community-acquired as well as hospital-acquired urinary tract infections and to determine the antibiotic resistance pattern of the most frequent organisms.
Methods: This is a retrospective cross sectional study of positive urine cultures of adult patients attending An-Najah National University Hospital (NNUH) between the period of Jan 2019 and Dec 2020.
Each patient’s age, sex, and urine culture results were obtained from the microbiology lab of NNUH. Microbiology reports included the isolated microorganisms and their antibiotic susceptibility patterns.
Results: A total of 798 patients were included in the study, of which 472 (59.1%) were female. Escherichia coli was the most common uropathogen, accounting for 37.8% of the CAUTI and 25.1% of the HAUTI. In CAUTI, E. coli was followed by E. faecalis (16.4%), Klebsiella pneumoniae (13.7%), E. faecium (6.5%), and Streptococcus agalactia (4.9%). Among HAUTIs, the second most common was Klebsiella pneumoniea (21.4%) followed by E. faecium (19.3%), E. faecalis (13.4%), and Pseudomonas aeruginosa (7%). The rates of ESBL-producing strains of E. coli were similar between CAUTI (54.1%) and HAUTI (53.2%).

coli from CAUTI and HAUTI was sensitive to carbapenems, amikacin, and nitrofurantoin. The antibiotics with the highest resistance rates were ampicillin, cefuroxime, cotrimoxazole, and ciprofloxacin. Resistance rates were higher in HAUTI than in CAUTI.

Conclusions: The UTI etiological profiles and antibiotic resistance patterns varied between CAUTI and HAUTI; thus, a different antibiotic therapy for various categories should be considered when initiating empirical antimicrobial therapies.

Introduction: Surgical antimicrobial prophylaxis (SAP), when used appropriately based on evidence-based guidelines, reduces the rate of infectious complications following endourological procedures without compromising patient outcomes.
Aims: to audit the appropriateness of the current SAP used in endourological surgeries based on international guidelines and report their associated outcomes (urinary tract infection (UTI) and bloodstream infection (BSI)).
Methodology: The adherence to international guidelines recommendations; AUA 2019 and EAU 2020, regarding indication, duration, choice, and dose of the antibiotics used in endourological procedures were assessed in two medical centers in Amman/Jordan. Also, patients were asked to conduct laboratory urine test to determine the rate of infectious complications within one-month post-procedure.
Results: Three hundred sixty-one patients were recruited for the study. The adherence rate to guidelines regarding indication, choice, and dose of pre-operative antibiotics was 90.3%, 2.8%, and 77.8% respectively. The duration was concordant with guidelines in only 3.4% of participants. A total of 41.8% of patients completed follow-up. Among those, 4.6% developed bacterial UTIs, and 0.7% developed BSI.
Conclusion: Adherence to SAP guidelines in endourological procedures is far from optimal, especially by an inappropriate selection of broad-spectrum antibiotics as the agent of choice and prolonged use of antibiotics after the procedure in the absence of any documented infectious complication.

Published: July 2023

Introduction. The primary goal of this article is to raise attentiveness about the critical need for vector-borne disease control in Nigeria in relation to One Health, as well as to examine existing understanding on this subject matter, which is quickly befitting as a valuable resource for public health policymakers and specialists across the country. Globally, there has been an increase in the number of vectors, which has resulted in an increase in vector-borne diseases. Thousands of individuals die every year as a consequence of vector-borne diseases, and there is an urgent need to manage these vectors.
Material and methods. The present research used PubMed, ResearchGate, WHO and other online databases with the following keywords “Climate change in Nigeria”, “Public health in Nigeria”, “Vector-borne Diseases”, “Nigeria population” and “One Health in Nigeria”.
Results. We observed that there has not been an implementation of the One Health approach against Vector-borne diseases in Nigeria.
Conclusions. The One Health strategy has the potential to address this issue. One Health is the concept that the health of human is intertwined with that of animals and our collective environment. Malaria is a vector-borne disease that is one of Nigeria's biggest health issues. However, land use changes such as deforestation, mining, and other activities have increased in Nigeria, while climate changes have increased internationally.

Abstract
The ages of solar-like stars have been at the center of many studies such as exoplanet characterization or Galactic-archeology. While ages are usually computed from stellar evolution models, relations linking ages to other stellar properties, such as rotation and magnetic activity, have been investigated. With the large catalog of 55,232 rotation periods, P
rot, and photometric magnetic activity index, S
ph from Kepler data, we have the opportunity to look for such magneto-gyro-chronology relations. Stellar ages are obtained with two stellar evolution codes that include treatment of angular momentum evolution, hence using P
rot as input in addition to classical atmospheric parameters. We explore two different ways of predicting stellar ages on three subsamples with spectroscopic observations: solar analogs, late-F and G dwarfs, and K dwarfs. We first perform a Bayesian analysis to derive relations between S
ph and ages between 1 and 5 Gyr, and other stellar properties. For late-F and G dwarfs, and K dwarfs, the multivariate regression favors the model with P
rot and S
ph with median differences of 0.1% and 0.2%, respectively. We also apply Machine Learning techniques with a Random Forest algorithm to predict ages up to 14 Gyr with the same set of input parameters. For late-F, G and K dwarfs together, predicted ages are on average within 5.3% of the model ages and improve to 3.1% when including P
rot. These are very promising results for a quick age estimation for solar-like stars with photometric observations, especially with current and future space missions.

Abstract
Lyα emission is possibly the best indirect diagnostic of Lyman continuum (LyC) escape since the conditions that favor the escape of Lyα photons are often the same that allow for the escape of LyC photons. In this work, we present the rest-frame UV–optical spectral characteristics of 11 Lyα emitting galaxies at 3 < z < 6—the redshift range that optimizes between intergalactic medium attenuation effects and temporal proximity to the epoch of reionization. From a combined analysis of JWST/NIRSpec and MUSE data, we present the Lyα escape fraction and study its correlation with other physical properties of galaxies that might facilitate Lyα escape. We find that our galaxies have low masses (80% of the sample with

We predict the LyC escape fraction in our sample to be low (0.03–0.07), although larger samples in the postreionization epoch are needed to confirm these trends.
