Modeling the global impact of reducing out-of-pocket costs for children’s surgical care

Over 1.7 billion children lack access to surgical care, mostly in low- and middle-income countries (LMICs), with substantial risks of catastrophic health expenditures (CHE) and impoverishment. Increasing interest in reducing out-of-pocket (OOP) expenditures as a tool to reduce the rate of poverty is growing. However, the impact of reducing OOP expenditures on CHE remains poorly understood. The purpose of this study was to estimate the global impact of reducing OOP expenditures for pediatric surgical care on the risk of CHE within and between countries. Our goal was to estimate the impact of reducing OOP expenditures for surgical care in children for 149 countries by modeling the risk of CHE under various scale-up scenarios using publicly available World Bank data. Scenarios included reducing OOP expenditures from baseline levels to paying 70%, 50%, 30%, and 10% of OOP expenditures. We also compared the impact of these reductions across income quintiles (poorest, poor, middle, rich, richest) and differences by country income level (low-income, lower-middle-income, upper-middle-income, and high-income countries). Reducing OOP expenditures benefited people from all countries and income quintiles, although the benefits were not equal. The risk of CHE due to a surgical procedure for children was highest in low-income countries. An unexpected observation was that upper-middle income countries were at higher risk for CHE than LMICs. The most vulnerable regions were Africa and Latin America. Across all countries, the poorest quintile had the greatest risk for CHE. Increasing interest in financial protection programs to reduce OOP expenditures is growing in many areas of global health. Reducing OOP expenditures benefited people from all countries and income quintiles, although the benefits were not equal across countries, wealth groups, or even by wealth groups within countries. Understanding these complexities is critical to develop appropriate policies to minimize the risks of poverty.
Coastal trapped waves and tidal mixing control primary production in the tropical Angolan upwelling system

Eastern boundary upwelling systems are hotspots of marine life and primary production. The strength and seasonality of upwelling in these systems are usually related to local wind forcing. However, in some tropical upwelling systems, seasonal maxima of productivity occur when upwelling favorable winds are weak. Here, we show that in the tropical Angolan upwelling system (tAUS), the seasonal productivity maximum is due to the combined effect of coastal trapped waves (CTWs) and elevated tidal mixing on the shelf. During austral winter, the passage of an upwelling CTW displaces the nitracline upward by more than 50 m. Thereby, nitrate-rich waters spread onto the shelf, where elevated vertical mixing causes a nitrate flux into the surface mixed layer. Interannual variability of the productivity maximum is strongly correlated to the amplitude of the upwelling CTW as seen in sea level data. Given that CTWs are connected to equatorial forcing, a predictability of the strength of the productivity maximum is suggested.
Cross-sectional insights into exercise physiology knowledge among medical students in Jordan

Objectives: Exercise physiology is a branch of physiology that studies how physical activity and exercise alter the structure and function of living organisms. Knowledge of exercise physiology is crucial to improve athletic performance, improve people’s ability to cope with extreme circumstances and approach chronic diseases. This research aimed to evaluate the knowledge of future healthcare professionals, namely, the medical students in Jordan regarding exercise physiology. Methods: Responses were collected from 524 undergraduate medical students enrolled in clinical clerkship. An online survey that evaluated participants’ basic understanding of various physiological concepts related to physical exercises, such as respiratory exchange ratio, physical fitness, V̇O2 max and exercise at high altitudes was employed in the study. Results: 63.2% of participants had a poor level of exercise physiology knowledge. Misconceptions regarding V̇O2 max definition (93.3%), application (46.4%), significance (35.6%) and related physiological factors (48.7%) were observed. Students had misconceptions about physical fitness evaluation questions (52.5%, 39%, and 41.8%, respectively). Student proportions of 37%, 41%, 80.3% and 73.1% showed misconceptions about muscle groups and energy systems during training, training prescription variables, respiratory exchange ratio, and high-altitude performance, respectively. Significant differences in knowledge levels were found based on respondent characteristics (p < 0.05). Conclusions: Knowledge of exercise physiology is more than desirable for medical professionals. Therefore, efforts must be made to increase awareness and improve knowledge about basic physiological fundamentals related to exercise physiology among medical students in Jordan, as they represent the backbone of healthcare professionals of the future who will deal with medical conditions related to physical activity and exercise.
Prevention and control of hospital-acquired infections with multidrug-resistant organism: A review

Multidrug-resistant is defined as nonsusceptibility to at least 1 agent in 3 or more antimicrobial categories. Controlling the spread of drug-resistant organisms is a key step in the management of hospital-acquired infections (HAIs). To review the progress of research on the prevention and control of HAIs with multidrug-resistant organism (MDRO) in the past 5 years, and to provide reference for the development of comprehensive measures for the prevention and control of HAIs with MDRO. We conducted a search in the PUBMED database for studies related to MDRO and HAIs from 2018 to 2023, then integrated this data with information sourced from the U.S.A. The Centers for Disease Control and Prevention. Utilizing information technology to monitor and provide feedback on hand hygiene practices can enhance compliance. Environmental disinfection techniques such as ultraviolet or hydrogen peroxide demonstrate potential in reducing MDRO transmission. While some studies support that contact isolation measures for MDRO-infected or colonized patients can reduce HAIs, others do not confirm this outcome. Approaches for MDRO colonization among patients or physicians may mitigate MDRO transmission risk. Implementing clusterization interventions proves to enhance efficiency and cost-effectiveness in preventing and controlling MDRO. Early screening for pathogen species emerges as a valuable strategy aiding in antimicrobial use control. Combined with evidence from the literature, implementing clusterization interventions that include measures such as monitoring and feedback on hand hygiene and improved environmental disinfection techniques can help prevent and control HAIs with MDRO. However, further clinical studies are needed to validate the optimal clusterization intervention.
Clinical application of metagenomic next-generation sequencing in patients with different organ system infection: A retrospective observational study

Microbiological identification is essential for appropriate treatment, but conventional methods are time-consuming and have a low sensitivity. In contrast, metagenomic next-generation sequencing (mNGS) is a culture-free and hypothesis-free technique that can detect a wide array of potential pathogens. This study aimed to reveal the overall diagnostic value of mNGS for infectious diseases of different organ systems and compare the sensitivity and specificity of mNGS with conventional methods. In a retrospective cohort study, 94 patients with mNGS results were enrolled, and clinical data were recorded and analyzed to compare the positive rate of mNGS with traditional methods including as smears, serological tests, and traditional PCR, etc. In this study, mNGS and culture were both positive in 12.77% cases and were both negative in 23.4% cases. There were positive results in 56 cases (54.26%) only by mNGS and 4 cases (4.26%) were positive only by culture. There were significant differences in sensitivity of pathogen detection between of ID and NID group for mNGS (χ2 = 10.461, P = .001)and conventional methods(χ2 = 7.963, P = .005). The positive predictive values and negative predictive values of diagnosing infectious disease by mNGS were 94.12% and 30.77%, respectively. mNGS increased the sensitivity rate by approximately 53.66% compared with that of culture (78.05% vs24.39%; χ2 = 47.248, P < .001) and decreased the specificity rate by 12.5% compared with that of culture (66.67% vs 100.0%; χ2 = 4.8, P = .028). mNGS can identify emerging or rare pathogen and further guide treatment regimens. mNGS has advantages in identifying overall pathogens and bacteria, however, there was no obvious advantage in identifying fungi, virus and tuberculosis. mNGS has higher specificity than conventional methods in identifying pathogens and advantages in detecting emerging or rare pathogens.
Sex‐specific disparities in COVID‐19 outcomes

Abstract Objectives Sex‐specific disparities in morbidity and mortality of COVID‐19 illness are not well understood. Neutralizing antibodies (Ab) may protect against severe COVID‐19 illness. We investigated the association of sex with disease progression and SARS‐CoV‐2 Ab response. Methods In this exploratory analysis of the phase 3, multicenter, randomized, placebo‐controlled Convalescent Plasma in Outpatients (C3PO) trial, we examined whether sex was associated with progression to severe illness, defined as a composite of all‐cause hospitalization, emergency/urgent care visit, or death within 15 days from study enrollment. Patients had a positive severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) test, symptom onset within 7 days, stable condition for emergency department discharge, and were either ≥50 years old or had at least one high‐risk feature for disease progression. Patients received blinded convalescent plasma or placebo in a 1:1 fashion and were evaluated on days 15 and 30 after infusion. Blood samples were collected on day 0 (pre‐/post‐infusion), 15, and 30 to measure Ab levels with the Broad Institute using the Plaque Reduction Neutralization Test assay. Results Of 511 patients enrolled (median age 54 [Iinterquartile range 41–62] years, 46% male, 66% white, 20% black, 3.5% Asian), disease progression occurred in 36.7% of males and 25.9% of females (unadjusted risk difference 10.8%, 95% confidence interval [CI], 2.8–18.8%). Sex‐disparities did not persist when adjusted for treatment group, age, viremic status, symptom onset, and tobacco use (adjusted risk difference 5.6%, 95% confidence interval [CI], −2.2% to 13.4%), but were present in the subgroup presenting 3 or more days after symptom onset (adjusted risk difference 12.6%, 95% CI, 3.4% to 21.9%). Mean baseline Ab levels (log scale) available for 367 patients were similar between sexes (difference 0.19 log units, 95% CI, −0.08 to 0.46). The log‐scale mean increase from baseline to day 15 after adjusting for treatment assignment and baseline levels was larger in males than females (3.26 vs. 2.67). A similar difference was noted when the groups were subdivided by outcome. Conclusions Progression of COVID‐19 was similar in males and females when adjusted for age, tobacco use, and viremia status in this study. However, in the cohort presenting 3 or more days after symptom onset, COVID‐19 outcomes were worse in males than females. Neutralizing Ab levels increased more in males but did not correlate with sex differences in outcomes.
Application of the 2022 ACR/EULAR criteria to Chinese patients with previously diagnosed eosinophilic granulomatosis with polyangiitis: The concordance rate between the 2022 ACR/EULAR criteria and the 1990 criteria for EGPA in China

This study aimed to investigate the concordance rate between the 2022 American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) criteria and the 1990 criteria for eosinophilic granulomatosis with polyangiitis (EGPA) in Chinese patients. 68 patients were diagnosed with EGPA according to the 1990 ACR criteria in the Department of Respiratory and Critical Care Medicine, Beijing Chao-yang Hospital Department, from May 2005 to December 2022, and those patients were reclassified using the 2022 ACR/EULAR criteria for EGPA. Among the 68 patients, 88.2% (60 cases) met the 2022 ACR/EULAR criteria for EGPA, and 11.8% (8 cases) patients failed to meet the new criteria. Only 66.2% of the patients were detected blood eosinophil count ≥ 1 × 109/L, while more patients (77.9%) met the item blood eosinophil count > 10% in the 1990 criteria. The report rate of nasal polyps was 13.2% in these patients. The concordance rate between the 2022 ACR/EULAR criteria and the 1990 criteria for EGPA was 88.2%. Compared with the 1990 criteria, the 2022 ACR/EULAR put more weighting on the blood eosinophil count and nasal polyps, while the diagnostic rate of them is low in Chinese patients. Thus improving the positive rate is important and routinely screening for nasal polyps should be performed in the future.
Gender differences in trachomatous scarring prevalence in a formerly trachoma hyperendemic district in Tanzania

Background Trachoma is a chronic conjunctivitis caused by the bacterium Chlamydia trachomatis. Repeated infections lead to trachomatous conjunctival scarring which can progress to potentially blinding trachomatous trichiasis (TT). In trachoma hyperendemic conditions, women compared to men have an increased risk of scarring and TT, which can progress to blinding corneal opacification. This study determined if there were gender differences in scarring prevalence and severity when trachoma prevalence approaches elimination, in a formerly trachoma hyperendemic region. Methodology/Principal findings A cross-sectional prevalence study was conducted amongst adults age 15 years and older in Kongwa district, Tanzania in 2019. 3168 persons over age 15 years agreed to be examined and had at least one eye with a gradable image. Ocular photographs were graded for scarring according to a published four-step severity scale. Overall, about half of all study participants had scarring. However, more females (52.3%) had any scarring compared to males (47.2%), OR = 1.22 (95% CI = 1.05–1.43). For every year increase in age, there was a 6.5% increase in the odds of having more severe scarring (95% CI: 5.8%, 7.2%). Women were more likely than men to have severe scarring, OR 2.36 (95% CI: 1.84–3.02). Residence in a community with TF≥10% was associated with a 1.6-fold increased odds of any scarring. Conclusions/Significance Overall scarring prevalence and more severe scarring prevalence was higher in females compared to males, even adjusting for age and community TF prevalence. The data suggest that processes occur that lead to women preferentially progressing towards more severe scarring compared to men.
Acupoint herbal patching for postherpetic neuralgia: A systematic review and meta-analysis

Background: This study aimed to systematically evaluate the clinical effectiveness and safety of acupoint herbal patching in the treatment of postherpetic neuralgia. Methods: Eight databases including PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure, Wan-Fang Database, China Biomedical Literature Service System, and Chongqing VIP Chinese Science were searched. The search time was set to October 2023. Two researchers independently screened the literature according to the inclusion and exclusion criteria; extracted the basic information, acupoints, Chinese herbal medicine, pain score, sleep score, depression score, and other information of the subjects, and independently assessed the risk of bias by 2 researchers. Meta-analysis of the included studies was performed using the StataMP 16 software. Results: Fifteen studies with 1362 participants were included in this meta-analysis. Ashi is the acupoint frequency at the forefront, and Borneol is the Chinese herbal medicine frequency at the forefront. The acupoint herbal patching group showed significant improvements in visual analog score (SMD: −2.09; 95% Cl: −2.77, −1.42; P < .001), sleep score (SMD: −1.58; 95% Cl: −2.11, −1.05; P < .001), depression score (SMD: −1.61; 95% Cl: −2.22, −0.99; P < .001), Chinese medicine syndrome score (SMD: −2.32; 95% Cl: −2.84, −1.80; P = .06), dermatology life quality index (weighted mean differences: −4.11; 95% Cl: −4.58, −3.63; P = .98), and related laboratory indicators compared to the control group, and the total effective rate was significantly higher (relative risk: 1.20; 95% confidence interval: 1.15, 1.26; P = .99) than the control group. Two studies reported adverse reactions, but the 2 groups were not statistically significant. Conclusions: Acupoint herbal patching intervention in postherpetic neuralgia is effective in improving the pain, sleep, anxiety, depression, quality of life of patients, and related laboratory indicators.
Proliferation and immunohistochemistry for p53, CD25 and CK20 in predicting prognosis of non-muscle invasive papillary urothelial carcinomas

Non-muscle invasive papillary urothelial carcinoma is a prevalent disease with a high recurrence tendency. Good prognostic and reproducible biomarkers for tumor recurrence and disease progression are lacking. Currently, WHO grade and tumor stage are essential in risk stratification and treatment decision-making. Here we present the prognostic value of proliferation markers (Ki67, mitotic activity index (MAI) and PPH3) together with p53, CD25 and CK20 immunohistochemistry (IHC). In this population-based retrospective study, 349 primary non-muscle invasive bladder cancers (NMIBC) were available. MAI and PPH3 were calculated manually according to highly standardized previously described methods, Ki-67 by the semi-automated QPRODIT quantification system, p53 and CD25 by the fully automated digital image analysis program Visipharm® and CK20 with the help of the semi-quantitative immunoreactive score (IRS). Survival analyses with log rank test, as well as univariate and multivariate Cox regression analyses were performed for all investigated variables. Age and multifocality were the only significant variables for tumor recurrence. All investigated variables, except gender, were significantly associated with stage progression. In multivariate analysis, MAI was the only prognostic variable for stage progression (p<0.001).
Recurrent viral capture of cellular phosphodiesterases that antagonize OAS-RNase L

Significance Horizontal gene transfer (HGT) of host genes to virus genomes is a common but underappreciated means of RNA virus evolution. We used a combination of sequence comparisons and protein structure predictions to reconstruct the evolutionary history of viral phosphodiesterase (PDE) genes. PDEs encoded by nidoviruses and rotaviruses appear to be descended from host AKAP7-like PDE genes and are potent antagonists of the antiviral OAS-RNase L pathway. By characterizing the evolutionary history of these genes, we shed light on how HGT shaped virus interactions with host immunity. By integrating evolutionary approaches, we overcome challenges posed by vast sequence divergence across viral and cellular PDE diversity to show that cellular AKAP7-like PDEs were recurrently acquired by two families of RNA viruses.
Utilisation of dental services by refugees in Germany: Results of the population-based RESPOND survey

Background The utilisation of outpatient dental services is an important indicator for monitoring healthcare provision in Germany. In the general population, the 12-month prevalence of dental service utilization is 82.2 %. For refugees, this indicator has hardly been measured, although studies suggest an objectively high need for dental care. Methodology As part of the population-based cross-sectional RESPOND study (2018), self-reported health and healthcare, including the use of dental services, was assessed in three representative, random samples of refugees residing in reception and shared accommodation centres in Baden-Württemberg and Berlin. Results The indicator was available for 68.8 % (594) of the 863 surveyed refugees. Overall, 38.2 % of the respondents stated that they had utilised dental services in the previous 12 months, whereas 41.4 % had never used any dental care in Germany. Conclusions The utilisation of dental services among refugees is very low compared to the level of utilisation in the general population. It reflects a discrepancy between access and needs.
Reducing dietary crude protein: effects on digestibility, N balance, and blood metabolites in late-lactation Holstein cows.

Our objectives were to determine the effects of reducing dietary crude protein (CP) concentration on nutrient digestibility, rumen function, N balance, and serum AA concentration for dairy cows in late lactation. At the initiation of the experimental period, we stratified Holstein cows (n = 128; mean ± standard deviation 224 ± 54 d in milk) by parity and days pregnant (86 ± 25 d) and assigned them to 1 of 16 pens. For 3 wk, all cows received a covariate diet containing 16.9% CP [dry matter (DM) basis]. For the subsequent 12 wk, we assigned pens to 1 of 4 treatments containing 16.2, 14.4, 13.4, or 11.9% CP (DM basis) in a randomized complete block design. Diets were fed as a total mixed ration once daily. To reduce dietary CP, we replaced soybean meal with soybean hulls in the concentrate mix (DM basis). Diet evaluations suggested that several EAA, especially His, limited productivity as dietary CP declined. Digestibility of DM and CP decreased linearly with dietary CP reduction. Digestibility of neutral detergent fiber and potentially digestible neutral detergent fiber tended to respond in a quadratic pattern with the greatest digestibility at intermediate treatments. The reduction in dietary CP did not affect ruminal pH, but ruminal ammonia-N and branched-chain VFA concentrations declined linearly. The concentration of milk urea-N and plasma urea-N, secretion of milk N, and excretions of fecal N, urinary N, urinary urea-N, and unaccounted N decreased linearly with the reduction in dietary CP concentration. Urinary N expressed as a percentage of N intake was unaffected by dietary CP. Serum concentrations of total essential AA and non-essential AA were unaffected by dietary CP concentration. However, the ratio of essential to non-essential AA decreased with decreasing dietary CP. Serum 3-methylhistidine concentration increased linearly with decreasing dietary CP concentration, indicating greater skeletal muscle breakdown. Although our trial confirmed that reducing dietary CP decreased absolute excretion of urinary N, diet evaluations suggested that milk protein production decreased as certain essential AA became increasingly limited. Thus, reduced-CP diets have the potential to lessen reactive-N outputs of late lactation cows, but more research is needed to design diets that minimize deleterious effects on productivity.
