Contamination of microplastics in mangrove sediment cores from Lach Huyen area, Hai Phong city, Vietnam

Microplastics have been found in coastal ecosystems since the 1970s, causing many negative impacts on the environment and aquatic organisms. In the present study, we examined the microplastic concentration and sediment grain size in mangrove sediment cores near Lach Huyen Port, Hai Phong city, Vietnam. The microplastic concentration in mangrove sediments varied from 0-3150 particles/kg with an average value of 1309.1±124.8 particles/kg, much higher than in similar regions worldwide. They are mainly secondary microplastics with various colors and sizes. The microplastic types include 80% of microfibers and the rest is a mixture of microfoam, microfragment, and microfilm. Research results showed that the concentration of microplastics tends to decrease from top to bottom of the sediment cores. However, the present study did not find any relationship between sediment grain size and microplastic abundance. Future studies should assess the pollution sources, factors influencing microplastic distribution, and the effects of microplastic contamination on coastal ecosystems in this area.
Distribution of bacteria and risk factors in patients with multidrug-resistant pneumonia in a single center rehabilitation ward

Stroke patients may have dysphagia and frequent aspiration increasing exposure to antibiotics and the chance of multidrug-resistant (MDR) bacteria infection. This study investigated clinical risk factors and related antibiotic use of MDR bacteria infection in stroke patients in the rehabilitation ward, hoping that it can help prevent and reduce the condition of MDR bacteria. A retrospective cohort study was conducted using the database of stroke patients with pneumonia admitted to the rehabilitation ward from January 1, 2020, to June 30, 2022. The selected stroke patients were divided into the MDR and non-MDR groups. Analyze the infection bacteria of the 2 groups. Forward logistic regression was applied to identify possible independent MDR bacteria infection risk factors. A total of 323 patients were included. The top 3 common MDR pathogens were Pseudomonas aeruginosa, Klebsiella pneumoniae, and Acinetobacter baumannii. Almost all Pseudomonas aeruginosa and Acinetobacter baumannii are resistant to ertapenem. National Institute of Health stroke scale at admission was associated with MDR bacteria infection pneumonia (OR [odds ratio] = 1.078, 95%CI [1.017, 1.142]). Long-term tracheotomy (OR = 2.695, 95%CI [1.232, 5.897]), hypoalbuminemia (OR = 473, 95%CI [1.318, 4.642]), and bilateral cerebral hemisphere stroke (OR = 4.021, 95%CI [2.009, 8.048]) were significant clinical risk factors of MDR pneumonia after stroke. The detection rate of MDR bacteria has increased. Understanding the distribution and drug resistance of MDR bacteria in stroke patients with pneumonia in the neurological rehabilitation ward and the related susceptibility of MDR bacteria infection is necessary. This way, the treatment plan can be adjusted more timely, avoiding the abuse of antibiotics.
Orchestrating vesicular and nonvesicular membrane dynamics by intrinsically disordered proteins

Compartmentalization by membranes is a common feature of eukaryotic cells and serves to spatiotemporally confine biochemical reactions to control physiology. Membrane‐bound organelles such as the endoplasmic reticulum (ER), the Golgi complex, endosomes and lysosomes, and the plasma membrane, continuously exchange material via vesicular carriers. In addition to vesicular trafficking entailing budding, fission, and fusion processes, organelles can form membrane contact sites (MCSs) that enable the nonvesicular exchange of lipids, ions, and metabolites, or the secretion of neurotransmitters via subsequent membrane fusion. Recent data suggest that biomolecule and information transfer via vesicular carriers and via MCSs share common organizational principles and are often mediated by proteins with intrinsically disordered regions (IDRs). Intrinsically disordered proteins (IDPs) can assemble via low‐affinity, multivalent interactions to facilitate membrane tethering, deformation, fission, or fusion. Here, we review our current understanding of how IDPs drive the formation of multivalent protein assemblies and protein condensates to orchestrate vesicular and nonvesicular transport with a special focus on presynaptic neurotransmission. We further discuss how dysfunction of IDPs causes disease and outline perspectives for future research.
Forecasting Annual Patronage by Domestic and Foreign Tourists to Mole National Park, Ghana

The ecotourism industry contributes significantly to the economic development of a country as well as conserving its biodiversity. The introduction and development of ecotourism gives an economic and educational growth opportunity to the indigenous people that would not otherwise be available. Th is study employed the double exponential smoothing model to model the annual nu mber of domestic and foreign tourists who travel to Mo le National Park. Forecast with the models revealed that the number of do mestic tourists will continue to increase while that of the foreign tourists will decrease with time. Th is will have a negative impact on the industry and the country as a whole due to a possible decline in foreign exchange earnings. It is therefore reco mmended that management of the park and its stakeholders should work assiduously to develop and imp lement effective ecotouris m packages that will help attract mo re tourists especially foreigners.

Long-term survival after major trauma: a retrospective nationwide cohort study from the National Health Insurance Research Database

Background: Most trauma-related studies are focused on short-term survival and complications within the index admission, and the long-term outcomes beyond discharge are mainly unknown. The purpose of this study was to analyze the data from the National Health Insurance Research Database (NHIRD) and to assess the long-term survival of major trauma patients after being discharged from the index admission. Material and methods: This retrospective, observational study included all patients with major trauma (injury severity score ≥16) in Taiwan from 2003 to 2007, and a 10-year follow-up was conducted on this cohort. Patients aged 18–70 who survived the index admission were enrolled. Patients who survived less than one year after discharge (short survival, SS) and those who survived for more than one year (long survival, LS) were compared. Variables, including preexisting factors, injury types, and short-term outcomes and complications, were analyzed, and the 10-year Kaplan–Meier survival analysis was conducted. Results: In our study, 9896 patients were included, with 2736 in the SS group and 7160 in the LS group. Age, sex, comorbidities, low income, cardiopulmonary resuscitation event, prolonged mechanical ventilation, prolonged ICU length of stay (LOS), and prolonged hospital LOS were identified as the independent risk factors of SS. The 10-year cumulative survival for major trauma patients was 63.71%, and the most mortality (27.64%) occurred within the first year after discharge. Conclusion: 27.64% of patients would die one year after being discharged from major trauma. Major trauma patients who survived the index admission still had significantly worse long-term survival than the general population, but the curve flattened and resembled the general population after one year.
Prevalence of geographic atrophy in Nordic countries and number of patients potentially eligible for intravitreal complement inhibitor treatment: A systematic review with meta‐analyses and forecasting study

We systematically reviewed the literature on the prevalence of geographic atrophy (GA) in Nordic populations, conducted meta‐analyses on age‐stratified estimates, and calculated current and future number of patients and those potentially eligible for intravitreal complement inhibitor treatment. We followed the PRISMA guidelines, and our protocol was registered in PROSPERO. Ten databases were searched on 22 April 2023 for population‐based studies of GA prevalence. Based on clinical descriptive analyses of GA and eligibility criteria of the phase III studies for intravitreal pegcetacoplan (complement C3 and C3b inhibitor), we were able to calculate the proportion of patients with GA potentially eligible for therapy. Finally, we extracted population data for Nordic countries (Denmark, Finland, Iceland, Norway, and Sweden) from Eurostat, applied prevalence statistics to the extracted census and forecasting data to estimate the number of patients with GA, and then applied the proportion eligible for intravitreal pegcetacoplan therapy. We identified six studies with a total of 10 159 individuals. Prevalence of GA was estimated to 0.4% (95% confidence intervals [CI]: 0.2%–0.8%), 1.5% (95% CI: 0.7%–2.6%), and 7.6% (95% CI: 4.6%–11.3%) for individuals aged 60–69, 70–79, and 80+ years, respectively. In Nordic countries, we estimate a total of 166 307 individuals with GA in 2023, increasing to 277 893 in 2050. Of these, 90 803 individuals in 2023, increasing to 151 730 in 2050, are potentially eligible for intravitreal complement inhibitor treatment. Considering these large numbers, our study highlights the importance of this topic in the coming years and its potential to significantly impact our clinical practice, organization, and staffing.
Mitapivat reprograms the RBC metabolome and improves anemia in a mouse model of hereditary spherocytosis

Hereditary spherocytosis (HS) is the most common, nonimmune, hereditary, chronic hemolytic anemia after hemoglobinopathies. The genetic defects in membrane function causing HS lead to perturbation of the RBC metabolome, with altered glycolysis. In mice genetically lacking protein 4.2 (4.2–/–; Epb42), a murine model of HS, we showed increased expression of pyruvate kinase (PK) isoforms in whole and fractioned RBCs in conjunction with abnormalities in the glycolytic pathway and in the glutathione (GSH) system. Mitapivat, a PK activator, metabolically reprogrammed 4.2–/– mouse RBCs with amelioration of glycolysis and the GSH cycle. This resulted in improved osmotic fragility, reduced phosphatidylserine positivity, amelioration of RBC cation content, reduction of Na/K/Cl cotransport and Na/H-exchange overactivation, and decrease in erythroid vesicles release in vitro. Mitapivat treatment significantly decreased erythrophagocytosis and beneficially affected iron homeostasis. In mild-to-moderate HS, the beneficial effect of splenectomy is still controversial. Here, we showed that splenectomy improves anemia in 4.2–/– mice and that mitapivat is noninferior to splenectomy. An additional benefit of mitapivat treatment was lower expression of markers of inflammatory vasculopathy in 4.2–/– mice with or without splenectomy, indicating a multisystemic action of mitapivat. These findings support the notion that mitapivat treatment should be considered for symptomatic HS.
Effect of suture closure and staple closure on postoperative wound complications in patients undergoing knee replacement surgery: A meta‐analysis

Abstract The purpose of this meta‐analysis is to determine if the application of stitching in the closed area of the knee arthroplasty remains significantly superior to that of the staples. Data sources: EMBASE, Cochrane Libraryand, publications, and the Web of Science. Patients were treated with staples for closure of their wounds, or with conventional stitches for closure of wounds. The main findings were surgical site infection, wound dehiscence, and cutting time. The secondary results were the time to completion, the duration of the hospitalization, and the time to discharge. We incorporated the SIX trial into the meta‐analyses with Review Manager V.5. 3. The hazard ratio was computed as a therapeutic outcome with respect to the heterogeneity. For more than 50% of heterogeneous samples, we employed a stochastic effect model. The results showed that there was no significant difference in the degree of infection, the degree of dehiscence, the length of the cut and the degree of satisfaction of the wound. But the time to close the wound and the time to operate were significantly different. The time needed to close the wound was shorter than that of the suture (OR, −227. 22; 95% CI, −238. 74, −215. 69 p < 0. 0001); The time taken to replace the knee was also significantly lower among those who had been stapled sutures (OR, −5.46; 95% CI, −10. 43, −0.49 p = 0. 03). Wound closing materials are an afterthought for many orthopaedic surgeons. Together, the findings from a number of comparative studies indicate that the selection of wound closure materials might affect the outcome of the surgery. The evidence, however, is weak because of the heterogeneous approach adopted in earlier research. This study program is intended to provide guidance on how to select the best wound closure material for the purpose of identifying if there is any difference in the incidence of injuries among traditional stitches and staples.
Trend of blood pressure changes among children from 2012 to 2022: findings from student health surveillance in Eastern China

Objectives: The primary objective of this study is to examine the secular trends in blood pressure levels from 2012 to 2022 in eastern China. Additionally, to compare two standards [International Blood Pressure Reference for Children and Adolescents (ICBP) and the National Blood Pressure Reference for Chinese Han Children and Adolescents (CCBP)], we calculate the 95th percentile of blood pressure levels for students in developed regions (ECCBP). Secondly, the study aims to investigate potential contributors to elevated blood pressure, including sex, age, behaviors, and mental health. Lastly, the study seeks to estimate the total population aged 7–18 years with elevated blood pressure in Eastern China based on three references. Methods: The data used in this study were obtained from the Student Health Surveillance program in Jiangsu Province, which has been collecting data since 2012. Trained project members, skilled nurses, and doctors measured anthropometric variables. Additionally, online student questionnaires were administered in 2017, 2019, and 2021 to collect personal information behavior patterns, and mental health. Results: The study examined blood pressure changes in 123 013 children and adolescents in Eastern China from 2012 to 2022. Significant increases were observed in systolic blood pressure (SBP) and pulse pressure difference. Prevalence of elevated blood pressure followed a similar trend with ECCBP and CCBP, ranging from 17.2%/16.3% (2012–2015) to 11.6%/14.6% (2020–2022). Notably, BP with ICBP showed a significant increase in both prevalence and population, from 12.6% [6 713 679, 95% confidence interval (CI): 6 708 931 to 6 718 427] to 14.5% (7 004 208, 95% CI: 6 999 411 to 7 009 004). The study further emphasizes the significant impact of various risk factors on elevated blood pressure among children and adolescents, particularly the detrimental effect of depression on blood pressure, with the odds ratios (OR) in 2021 being 1.310 (95% CI, 1.290–1.330) for ECCBP, 1.239 (95% CI, 1.223–1.255) for CCBP, and 1.189 (95% CI, 1.176–1.202) for ICBP. Conclusion: The study revealed significant changes in the population and prevalence of elevated blood pressure in Eastern China from 2012 to 2022. The findings indicate a decline in the prevalence of elevated blood pressure (referred to as CCBP or ECCBP), while highlighting an increasing trend in elevated blood pressure (referred to as ICBP). Untreated high blood pressure can lead to serious cardiovascular diseases in adulthood, underscoring the importance of early prevention and management, particularly through nonpharmacological methods and regular monitoring for students in Eastern China. Raising awareness among educators, parents, and healthcare providers about the association between mental health and elevated blood pressure is essential.
Integrative Blood-Based Characterization of Oxidative Mitochondrial DNA Damage Variants Implicates Mexican Americans’ Metabolic Risk for Developing Alzheimer’s Disease

Alzheimer’s Disease (AD) continues to be a leading cause of death in the US. As the US aging population (ages 65+) expands, the impact will disproportionately affect vulnerable populations, e.g., Hispanic/Latinx population, due to their AD-related health disparities. Age-related regression in mitochondrial activity and ethnic-specific differences in metabolic burden could potentially explain in part the racial/ethnic distinctions in etiology that exist for AD. Oxidation of guanine (G) to 8-oxo-guanine (8oxoG) is a prevalent lesion and an indicator of oxidative stress and mitochondrial dysfunction. Damaged mtDNA (8oxoG) can serve as an important marker of age-related systemic metabolic dysfunction and upon release into peripheral circulation may exacerbate pathophysiology contributing to AD development and/or progression. Analyzing blood samples from Mexican American (MA) and non-Hispanic White (NHW) participants enrolled in the Texas Alzheimer’s Research & Care Consortium, we used blood-based measurements of 8oxoG from both buffy coat PBMCs and plasma to determine associations with population, sex, type-2 diabetes, and AD risk. Our results show that 8oxoG levels in both buffy coat and plasma were significantly associated with population, sex, years of education, and reveal a potential association with AD. Furthermore, MAs are significantly burdened by mtDNA oxidative damage in both blood fractions, which may contribute to their metabolic vulnerability to developing AD.
Myocardial scarring and recurrence of ventricular arrhythmia in patients surviving an out‐of‐hospital cardiac arrest

Prediction of recurrent ventricular arrhythmia (VA) in survivors of an out‐of‐hospital cardiac arrest (OHCA) is important, but currently difficult. Risk of recurrence may be related to presence of myocardial scarring assessed with late gadolinium enhancement cardiac magnetic resonance (LGE‐CMR). Our study aims to characterize myocardial scarring as defined by LGE‐CMR in survivors of a VA‐OHCA and investigate its potential role in the risk of new VA events.
Surgeon Implicit Association of Women With Supportive Roles in Medicine

Background: In a previous study, we documented patient implicit bias that surgeons are men. As a next step, we tested the implicit bias of surgeons that women in medicine have leading (chair, surgeon) or supporting roles (medical assistant, physician assistant). Questions/purpose: (1) What is the relationship between the implicit associations and expressed beliefs of surgeons regarding women as leaders in medicine? (2) Are there factors associated with surgeon implicit association and explicit preference regarding the roles of women in medicine? Methods: A total of 102 musculoskeletal surgeon members of the Science of Variation Group (88 men and 12 women) completed an implicit association test (IAT) of implicit bias regarding sex and lead/support roles in medicine and a questionnaire that addressed respondent demographics and explicit preference regarding women's roles. The IAT consisted of seven rounds with five rounds used for teaching and two rounds for evaluation. Results: On average, there was an implicit association of women with supportive roles (D-score: −48; SD 4.7; P < 0.001). The mean explicit preference was for women in leadership roles (median: 73; interquartile ranges: 23 to 128; P < 0.001). There was a correlation between greater explicit preference for women in a leading role and greater implicit bias toward women in a supporting role (ρ = 0.40; P < 0.001). Women surgeons and shoulder and elbow specialists had less implicit bias that women have supporting roles. Conclusion: The observation that musculoskeletal surgeons have an explicit preference for women in leading roles in medicine but an implicit bias that they have supporting roles—more so among men surgeons—documents the gap between expressed opinions and ingrained mental processing that is the legacy of the traditional “roles” of women in medicine and surgery. To resolve this gap, we will need to be intentional about promotion of and emersion in experiences where the leader is a woman. Level of evidence: III.
Pulse pressure and its association with body composition among Chinese men and women without diagnosed hypertension: the China Kadoorie Biobank

Background: Wide brachial pulse pressure (PP) has been associated with cardiovascular events, while its population distribution and association with body composition were poorly characterized in large populations. Methods: We evaluated the age and sex distributions of PP and its associations with body composition using baseline data from the China Kadoorie Biobank. A total of 434 200 participants without diagnosed hypertension were included in the analysis. Wide PP was defined as PP above 65 mmHg. Body composition variables, including BMI, waist circumference, waist-to-hip ratio (WHR), fat mass index (FMI), fat-free mass index (FFMI), and body fat percentage (BF%), were obtained from bioelectrical impedance analysis. Results: Overall, 14.3% of the participants had wide PP. Older age was consistently associated with wider PP in women but only after the andropause stage in men. The independent associations of BMI with wide PP were stronger than other body composition measures. The adjusted differences (men/women, mmHg) in PP per standard deviation (SD) increase in BMI (1.55/1.47) were higher than other body composition (BF%: 0.32/0.64, waist circumference: 0.33/0.39; WHR: 0.49/0.42). In addition, sex differences were observed. In men, the per SD difference in PP was higher for FFMI than for FMI (0.91 vs. 0.67, P < 0.05), whereas in women, it was higher for FMI than for FFMI (1.01 vs. 0.72, P < 0.05). Conclusion: Our nationwide population-based study presented the sex-specific distribution of PP over age and identified differential associations of PP with fat and fat-free mass in men and women.
