Feasibility and acceptability of a home-based virtual group exercise program in global Asian adult population: Baseline characteristics of a cohort study.

To determine the potential influence of a home-based virtual group exercise on people's long-term overall health consequences in global Asian population. We recruited 1021 participants from more than 7 regions across the globe including Taiwan, Malaysia, Singapore, Hong Kong, United States, Canada, Europe, and other regions. All the participants attended the virtual group Qigong exercise 60-minute bi-weekly with instructors for 6 months from June 2022 to December 2022. The physical, mental, and social well-being and other variables were measured via online questionnaires. The majority were 51 to 65 (50.6%) years old, female (90.2%), married (68.5%), and came from Taiwan (48.9%). Older adults had higher scores on measures of overall health and exercise adherence, and lower scores on measures of sleep quality and depressive symptoms compared with younger counterparts (P < .05). Most of them (95.3%) acknowledged that the improvement of health status was their motivating factor for exercise. Eighty nine percent of the participants believed that social media played an important role in this exercise program. This study will suggest such approach has great potential to reduce health disparities and can be implemented to underserved population who has limited recourses to join in-person exercise program.

Herbal Innovations in Candidiasis Management: A Comprehensive Review of Aloe Vera and Betel Leaf Extract Based Antifungal Gel

Candidiasis is the most prevalent fungal infection in people, and it is caused by C. albicans, both primary and secondary. Herbal medications are still the backbone of around 75-80% of the world's population, primarily in poor countries, for basic health care due to superior cultural acceptance, compatibility with the human body, and less adverse effects. herbal medicines are made from plants or plant parts and are used to cure injuries, diseases, and illnesses, as well as to promote health and healing. Plant-based medicinal products have a vital part in the healthcare of the remaining 20% of the population, who primarily live in developed nations. Aloe vera (Sanskrit Ghritakumari, Kumara; Hindi-Guarpatha, Ghikanvar) is a herb often known as the "medicinal plant" due to its numerous therapeutic characteristics. Aloe vera, botanically known as Aloe barbadensis Miller, is a member of the lily family. Aloe products are quite popular on the market and are extensively utilized in the skin care, cosmetics, medical, healthcare, and food industries. We are now employing piper betel leaf, commonly known as betel leaf (khaupan). Ayurvedic medicine from ancient India cites various medicinal advantages, including its antifungal properties. Candidiasis is the most prevalent fungal infection in people, and it is caused by C. albicans, both primary and secondary “Abstract” is a necessary section in a research paper. It may be constructed by gathering main points (summary) from each section of the research paper.

An Overview of the Thermochemical Valorization of Sewage Sludge: Principles and Current Challenges

With the increase in the world population and economic activity, the production of sewage sludge has grown, and its management has become an environmental problem. The most traditional method of managing sewage sludge is to dispose of it in landfills and on farmland. One way to valorize sewage sludge is to use thermochemical conversion processes to produce added-value products such as biochar, biofuels, and renewable gases. However, due to the high moisture content, thermochemical conversion using processes such as pyrolysis and traditional gasification involves multiple pre-treatment processes such as material drying. Hydrothermal thermochemical processes usually require high pressures, which pose many challenges to their application on a large scale. In this work, the advantages and disadvantages of the different existing thermochemical processes for the recovery of sewage sludge were analyzed, as well as the resulting industrial and environmental challenges. A SWOT analysis was carried out to assess the different thermochemical processes in terms of technical feasibility, economic viability, and broader market considerations.

Population Status and Conservation of the Largest Population of the Endangered François’ Langur (Trachypithecus francoisi) in Vietnam

François’ langur is an Endangered colobine inhabiting limestone habitats in southern China and northern Vietnam. Its global population has been estimated to be just more than 2000 mature individuals. Populations in Vietnam are highly fragmented with reportedly fewer than 200 adults in total and 50 in a single location. Although the François’ langur in Vietnam is highly imperiled as remnant populations persist in only three to four sites, little research has been carried out to provide a reliable estimate of its remaining population. In this study, we conducted field surveys in Lam Binh District, Tuyen Quang Province, northeastern Vietnam. In total, we recorded at least 16 groups of François’ langurs, with 156 individuals, raising the total number of individuals by approximately 10% compared to a previous study. The group structure, group size, activity budget, and density of the Lam Binh population resemble those reported in François’ langurs in China and other limestone langur species. The results show that the behavior ecology of limestone langurs significantly differs from that of forest langurs probably because they occupy separate habitats with distinctly different environmental variables. During our surveys, we detected a number of direct threats to this population, namely illegal logging, hunting, firewood collecting, hydropower development, grazing, and mining. It is recommended that the protection forest be elevated to the nature reserve status to better protect the most important population of the François’ langur in Vietnam.

Contribution of Millets in food and nutritional security to human being: Current status and future perspectives

Globally food and nutrition insecurity remain a serious challenge however the situation is more sever to the groups of people living under marginal and disadvantaged society. The causes of food and nutrition insecurity are multifaceted and complex, and influenced by a range of factors including high poverty, natural resource degradation, climate change, low level of market development, uncertain food support, and inadequate policy and institutional support. Considering the acute shortage of food and nutrition facing by global population, strengthening food and nutritional security is crucial in order to feed the ever-growing world population. One of the promising approaches of promoting millets, which requires low external inputs, a novel candidate for nutrients and adapted to thrive in harsh and dry environment. These crops play an important role in global food and nutrition security, and may have potential to contribute to sustainable food systems under changing climatic conditions. Keeping in view the importance of the millets in diversifying diet as well as a source of rich nutrition, we conducted an analysis by reviewing the research articles/reports/books as well as online databases to identify the prospects of millets crops crucial for continuous supply of food and nutrition, traditionally managed genetic resources for future crop improvement and making agricultural system resilient under changing climatic conditions. Evidences suggested from the meta-analysis that as a product of generations of agricultural landrace, there are range of millet crops are rich in nutrients, resilient, and adapted to location specific agricultural environments. Such millet crops in the existing cropping systems could support diverse food systems and nutrient suppliers and represent a broad gene pool to improving crops with suitable genetic interventions in the future. The study advocates for advancement in genomics coupled with molecular breeding for improving the genetic potential of millet crops and open avenues for developing sustainable food systems. The study also emphasis on developing strategies and roadmap for future research engagement and a policy interface to facilitate conservation and management of traditional landraces and associated indigenous knowledge of cultivation and consumption while adopting sustainable production of millet crops under marginal environmental conditions.

Seasonal human coronavirus humoral responses in AZD1222 (ChaAdOx1 nCoV-19) COVID-19 vaccinated adults reveal limited cross-immunity

BackgroundImmunity to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is now widespread; however, the degree of cross-immunity between SARS-CoV-2 and endemic, seasonal human coronaviruses (HCoVs) remains unclear.MethodsSARS-CoV-2 and HCoV cross-immunity was evaluated in adult participants enrolled in a US sub-study in the phase III, randomized controlled trial (NCT04516746) of AZD1222 (ChAdOx1 nCoV-19) primary-series vaccination for one-year. Anti-HCoV spike-binding antibodies against HCoV-229E, HCoV-HKU1, HCoV-OC43, and HCoV-NL63 were evaluated in participants following study dosing and, in the AZD1222 group, after a non-study third-dose booster. Timing of SARS-CoV-2 seroconversion (assessed via anti-nucleocapsid antibody levels) and incidence of COVID-19 were evaluated in those who received AZD1222 primary-series by baseline anti-HCoV titers.ResultsWe evaluated 2,020/21,634 participants in the AZD1222 group and 1,007/10,816 in the placebo group. At the one-year data cutoff (March 11, 2022) mean duration of follow up was 230.9 (SD: 106.36, range: 1–325) and 94.3 (74.12, 1–321) days for participants in the AZD1222 (n = 1,940) and placebo (n = 962) groups, respectively. We observed little elevation in anti-HCoV humoral titers post study-dosing or post-boosting, nor evidence of waning over time. The occurrence and timing of SARS-CoV-2 seroconversion and incidence of COVID-19 were not largely impacted by baseline anti-HCoV titers.ConclusionWe found limited evidence for cross-immunity between SARS-CoV-2 and HCoVs following AZD1222 primary series and booster vaccination. Susceptibility to future emergence of novel coronaviruses will likely persist despite a high prevalence of SARS-CoV-2 immunity in global populations.

Future of durum wheat research and breeding: Insights from early career researchers.

Durum wheat (Triticum turgidum ssp. durum) is globally cultivated for pasta, couscous, and bulgur production. With the changing climate and growing world population, the need to significantly increase durum production to meet the anticipated demand is paramount. This review summarizes recent advancements in durum research, encompassing the exploitation of existing and novel genetic diversity, exploration of potential new diversity sources, breeding for climate-resilient varieties, enhancements in production and management practices, and the utilization of modern technologies in breeding and cultivar development. In comparison to bread wheat (T. aestivum), the durum wheat community and production area are considerably smaller, often comprising many small-family farmers, notably in African and Asian countries. Public breeding programs such as the International Maize and Wheat Improvement Center (CIMMYT) and the International Center for Agricultural Research in the Dry Areas (ICARDA) play a pivotal role in providing new and adapted cultivars for these small-scale growers. We spotlight the contributions of these and others in this review. Additionally, we offer our recommendations on key areas for the durum research community to explore in addressing the challenges posed by climate change while striving to enhance durum production and sustainability. As part of the Wheat Initiative, the Expert Working Group on Durum Wheat Genomics and Breeding recognizes the significance of collaborative efforts in advancing toward a shared objective. We hope the insights presented in this review stimulate future research and deliberations on the trajectory for durum wheat genomics and breeding.

Strategies for Treating Acute Migraines and Identifying Triggers. Literature review

Introduction Migraine, a prevalent neurological disorder affecting a substantial portion of the global population, poses a significant burden on individuals' overall quality of life. While the exact pathophysiological mechanisms underlying migraine headache attacks remain elusive, the involvement of trigeminal pathway activation is well-documented. A multitude of factors, collectively termed triggers, have been identified as capable of precipitating migraine episodes, ranging from dietary components to environmental stimuli such as bright lights and weather fluctuations. Migraine headaches typically manifest as throbbing pain localized predominantly on one side of the head and are often accompanied by a constellation of additional symptoms including photophobia, phonophobia, and nausea. The management of migraine involves a diverse array of therapeutic modalities tailored to the specific characteristics of the pain experienced. These may include the administration of non-steroidal anti-inflammatory drugs (NSAIDs), paracetamol, triptans, and antiemetics, among others. This study endeavors to explore the most prevalent triggers implicated in migraine onset, as well as contemporary treatment strategies, with an emphasis on incorporating the latest research findings and therapeutic advancements in this evolving field. Aim of the study This review aims to identify symptoms, triggers of acute migraine and solutions in its treatment process, including latest developments. Material and method This article presents the current state of knowledge about acute migraine, triggers and treatment options in various scientific articles. Publications describing acute migraine attacks and treatments including the most recent reports in the field were reviewed using the PubMed platform. The search included the keywords ‘migraine, 'migraine triggers', 'triptans', 'migraine with aura'.

Placenta Accreta Spectrum Management and Outcomes: A Comparative Analysis of Syrian Refugees and Turkish Citizens Giving Birth in a Tertiary Hospital

Aim: Placenta accreta spectrum disorders (PAS) are a global threat to maternal well-being. The aim of this study was to assess differences in clinical characteristics and maternal outcomes between Turkish natives and Syrian refugees giving birth with a diagnosis of PAS at a tertiary centre, and to experience the management of this condition in the unique context of Türkiye, home to one of the world's largest refugee populations. Material and Method: A retrospective study was conducted using the medical records of 228 singleton pregnancies at high risk of PAS, between January 2019 and October 2022. PAS risk assessment was initially performed by ultrasound at mid-trimester, with diagnosis confirmed histologically or clinically, indicating the presence of placental retention following attempted manual removal. The study population was divided into two groups: native and refugee. We investigated disparities in demographic and medical characteristics and primary maternal and neonatal outcomes. Results: The study found an increased prevalence of previous cesarean delivery (p=0.005), anterior placenta (p

Variability in the prevalence of inappropriate medication use among older adults: A review highlighting the importance of screening methods and database types.

The global older population is growing rapidly, and the rise in polypharmacy has increased potentially inappropriate medication (PIM) encounters. PIMs pose health risks, but detecting them automatically in large medical databases is complex. This review aimed to uncover PIM prevalence in individuals aged 65 years or older using health databases and emphasized the risk of underestimating PIM prevalence due to underutilization of detection tools. This study conducted a broad search on the Medline database to identify articles about the prevalence of PIMs in older adults using various databases. Articles published between January 2010 and June 2023 were included, and specific criteria were applied for study selection. Two literature reviews conducted before our study period were integrated to obtain a perspective from the 1990s to the present day. The selected papers were analysed for variables including database type, screening method, adaptations and PIM prevalence. The study categorized databases and original screening tools for clarity, examined adaptations and assessed concordance among different screening methods. This study encompassed 48 manuscripts, covering 58 sample evaluations. The mean prevalence of PIMs within the general population aged over 65 years was 27.8%. Relevant heterogeneity emerged in both the utilized databases and the detection methods. Adaptation of original screening tools was observed in 86.2% (50/58) of cases. Half of the original screening tools used for assessing PIMs belonged to the simple category. About a third of the studies employed less than half of the original criteria after adaptation. Only three studies used over 75% of the original criteria and more than 50 criteria. This extensive review highlights PIM prevalence among the older adults, emphasizing method intricacies and the potential for underestimation due to data limitations and algorithm adjustments. The findings call for enhanced methodologies, transparent algorithms and a deeper understanding of intricate rules' impact on public health implications.

WEARABLE CARDIOVERTER DEFIBRILLATOR IN PATIENT WITH TRANSIENT RISK OF SUDDEN CARDIAC DEATH : SINGLE CENTRE EXPERIENCE

Abstract Background Cardiovascular disease is still the first cause of death, with sudden cardiac death ( SCD) as a first presentation in 25% of cases, related to coronary artery disease. Implantable cardioverter defibrillator (ICD) demontrated a reduction of SCD in high risk patients with good functional status. However the risk of SCD should be transient, so the use of a wearable cardioverter defibrillator (WCD) is considered in current guidelines and in clinical practice. The purpose of this study was to investigate the safety and the adherence to WCD in a real world population; moreover we reviewed the rate of ICD implantation after WCD use. Methods We considered consecutively 96 patients discharged from Piacenza cardiology department for potentially transient high risk of SCD, weared a WCD from August 2017 to June 2023. The patients were discharged in high risk mode of SCD with WCD protection and followed through remote monitoring or outpatient.A clinical and echocardiographic evalutation was performed at baseline and repeated at the end of the WCD use period. Results Out of 95 patients , with average age 66,0 ±11,1 years old and baseline average left ventricular ejection fraction (LVEF) 28,6±7,5, 81,2% were males, 72,9% suffered from arterial hypertension, 26% diabetes mellitus, 13,5% peripheral vascular disease, 14,6% chronic renal failure, 4,1% previous stroke.66% of these patients weared WCD for severe systolic disfunction in ischemic cardiac disease after recent myocardial infarction, after percutaneous coronary intervention or coronary artery bypass graft, 4% after removal of an infected ICD, 6% whilst awaiting completion of diagnostic tests (chanalopathies/right arrhythmogenic ventricular cardiomyopathy), 24% newly diagnosed cardiomyopathy. The average wearing time of WCD was 22,7±3,1 hours daily. We received these events: 1 sustained ventricular tachicardia, 2 non sustained ventricular tachicardia, 5 atrial fibrillation with 3 T wave oversensing. One patient recedived inappropriate shock. One death was detected due to severe heart failure. After 56,0±37,8 days of average wearing time 52% of patients were scheduled for ICD implantation. Conclusions In our experience we may consider that WCD use is effective, safe and with a good adherence in all patients. The WCD allows saving resources preventing inapprpriate ICD implantation in patient with transient SCD risk.

SGLT2i IN THE REAL WORLD: DATA FROM THE PONTE (bridge) HF PROJECT (PDTA FOR INTEGRATED TERRITORY HOSPITAL FOLLOW-UP OF PATIENTS WITH HEART FAILURE)

Abstract Background Over the last few years, treatment with sodium glucose cotransporter 2 inhibitors (SGLT2i) dapaglifozin and empaglifozin was shown to reduce the combined risk of cardiovascular death and/or hospitalization for heart failure (HF) among patients with heart failure with reduced ejection fraction. Subsequent RCTs have demonstrated similar reduction in the combined endpoint also in patients with left ventricular ejection fraction (LVEF) &amp;gt;40%. Nevertheless, real world data on the current state of implementation of SGLT2i therapy in HF clinical practice are scarce. The aim of the study was therefore to evaluate the impact of SGLT2i treatment in a real world population of HF patients. Methods 527 consecutive patients with HF, treated with SGLT2i and with 6 months of follow-up already enrolled in the PONTE (PDTA FOR THE INTEGRATED FOLLOW-UP IN THE HOSPITAL TERRITORY OF THE PATIENT WITH HEART FAILURE) HF project, a care model implemented in Puglia region (Italy) based on hospital-territory integration aimed at the optimized management of patient with HF after hospitalization, were considered for the study. Demographic, clinical, laboratory and instrumental characteristics, changes in NYHA class, creatinine, NT-proBNP, medications, LVEF after initiation of therapy with SGLT2i were evaluated. Results The 527 enrolled patients (mean age of 67,40 years, 75% hypertensive, 39% diabetic, 51% ischemic heart disease, 52% with ICD, 35% with atrial fibrillation) were in NYHA class I in 3,2% of cases, class II in 56,6%, class III in 38,5%, class IV in 1,7%. Mean LVEF was 34,20% (63% of patients had LVEF &amp;lt;35%), NT-proBNP 2606,86 pg/ml, creatinine 1,19 mg/dl. 95,1% of patients was on treatment with beta-blockers, 52,7% with ACE inhibitors, 55,1% with ARNI. After a follow-up of 6 months, a reduction of patients in NYHA classes III+IV from 40,2 to 19,0% as well as an increase in patients in classes I+II from 59,8 to 81,0% (NYHA I increasing from 3,2 to 14,6%) were observed. Furthermore, mean LVEF increased from 34,20 to 37,68% and patients taking loop diuretics reduced from 83,9 to 77,4%. Creatinine remained stable (1,19 vs 1,21 mg/dl), while NT-proBNP lowered from 2606,86 to 1603,32 pg/ml. Conclusions Our real world data on SGLT2i in HF patients seem to confirm the efficacy of this class of drugs in a short term follow-up, with a positive effect on symptoms (improvement in NYHA class and fewer patients taking loop diuretics), NT-proBNP and LVEF.

REMOTE CARDIAC DEVICE MANAGEMENT: REAL–WORLD INSIGHTS AND CHALLENGES

Abstract Background telemedicine plays a crucial role in managing patients with Cardiac Implantable Electronic Devices (CIEDs), offering unique technical and clinical benefits. This study explores the characteristics of a real–world population of CIED recipients undergoing entirely remote follow–up. Methods and Results in a prospective evaluation of 808 consecutive CIED patients from two Italian Cardiology Centers (2021–2023), initial on–site assessments were followed by remote evaluations, either scheduled or alert–triggered. The majority received pacemakers (68.8%), with others having Implantable Defibrillators (19.3%) or Implantable Loop Recorders (11.9%). The average age was 75.6±12.6 years, and 42% were female. Most of the patients were retired (83.3%), and 73% required at least one caregiver. The EQ–5D score indicated a lower quality of life (8.9±4.3) compared to the Italian general population. During the observation period (20.6 months), 34.9% of patients were admitted to the hospital, with 50% of cases being cardiovascular–related. Heart failure was the most common cause (13.2%). Device–related issues prompted outpatients’ cardiology clinic Department evaluations in 13.4% of cases. The telemedicine program produced 2780 remote transmissions, with 23% being automatic alerts. In–clinic evaluations were 1313, with a mean duration of 19.2 minutes. Atrial fibrillation (AF) history was prevalent (40.2%), and 719 AF episodes occurred during the observation period. Conclusions Managing CIED patients via telemedicine is feasible but requires structured organization considering patient characteristics and possible outcomes. AF management is crucial, given its high prevalence. Older age and compromised quality of life are significant factors, partly mitigated by the widespread presence of caregivers. Despite remote follow–up, many patients access healthcare structures for cardiovascular reasons, emphasizing the need for distinct pathways for device–related and general care necessities.

Predicting of aging population density by a hybrid grey exponential smoothing model (HGESM): a case study from Sri Lanka

PurposeThe global population has been experiencing an unprecedentedly rapid demographic transition as the populations have been growing older in many countries during the current decades. The purpose of this study is to introduce a Grey Exponential Smoothing model (GESM)-based mechanism for analyzing population aging.Design/methodology/approachTo analyze the aging population of Sri Lanka, initially, three major indicators were considered, i.e. total population, aged population and proportion of the aged population to reflect the aging status of a country. Based on the latest development of computational intelligence with Grey techniques, this study aims to develop a new analytical model for the analysis of the challenge of disabled and frail older people in an aging society.FindingsThe results suggested that a well-defined exponential trend has been seen for the population ages 65 and above, a total of a million) during 1960–2022; especially, the aging population ages 65 and above has been rising rapidly since 2008. This will increase to 24.8% in 2040 and represents the third highest percentage of elderly citizens living in an Asian country. By 2041, one in every four Sri Lankans is expected to be elderly.Originality/valueThe study proposed a GESM-based mechanism for analyzing the population aging in Sri Lanka based on the data from 1960 to 2022 and forecast the aging demands in the next five years from 2024 to 2028.

What’s UPDOG? A novel tool for trans-ancestral polygenic score prediction

Background Polygenic scores provide an indication of an individual’s genetic propensity for a trait within a test population. These scores are calculated using results from genetic analysis conducted in discovery populations. Where the test and discovery populations have similar ancestries, the predictions are better than when the ancestries differ. As many of the genetic analyses are conducted in European populations this hinders the potential for maximising predictions in many of the currently underrepresented populations in research. Methods To address this, UP and Downstream Genetic scoring (UPDOG) was developed to consider the concordance of genetic variation around lead variants between the discovery and test cohorts before calculating polygenic scores. Where there was non-concordance between the discovery cohort and an individual in the test cohort, the lead variant’s effect was down weighted for that individual. Results UPDOG was tested across four ancestries and six phenotypes and benchmarked against five existing tools for polygenic scoring. In approximately two-thirds of cases UPDOG improved trans-ancestral prediction, although the increases were small. Conclusions The development of novel methodologies aimed at maximising the efficacy of polygenic scores for the global population is of high importance and enables progress towards personalised medicine and universal equality in healthcare.

Sarcopenic Obesity and Cardiovascular Disease: An Overlooked but High-Risk Syndrome.

Sarcopenic obesity (SO), defined as the coexistence of excess fat mass and reduced skeletal muscle mass and strength, has emerged as an important cardiovascular risk factor, particularly in older adults. This review summarizes recent findings on the diagnosis, prevalence, health impacts, and treatment of SO. Growing evidence suggests SO exacerbates cardiometabolic risk and adverse health outcomes beyond either condition alone; however, the heterogeneity in diagnostic criteria and the observational nature of most studies prohibit the evaluation of a causal relationship. This is concerning given that SO is increasing with the aging population, although that is also difficult to assess accurately given wide-ranging prevalence estimates. A recent consensus definition proposed by the European Society for Clinical Nutrition and Metabolism and the European Association for the Study of Obesity provides a framework of standardized criteria to diagnose SO. Adopting uniform diagnostic criteria for SO will enable more accurate characterization of prevalence and cardiometabolic risk moving forward. Although current management revolves around diet for weight loss coupled with resistance training to mitigate further muscle loss, emerging pharmacologic therapies have shown promising results. As the global population ages, diagnosing and managing SO will become imperative to alleviate the cardiovascular burden.

Calcipotriol Nanosuspension-Loaded Trilayer Dissolving Microneedle Patches for the Treatment of Psoriasis: In Vitro Delivery and In Vivo Antipsoriatic Activity Studies.

Psoriasis, affecting 2-3% of the global population, is a chronic inflammatory skin condition without a definitive cure. Current treatments focus on managing symptoms. Recognizing the need for innovative drug delivery methods to enhance patient adherence, this study explores a new approach using calcipotriol monohydrate (CPM), a primary topical treatment for psoriasis. Despite its effectiveness, CPM's therapeutic potential is often limited by factors like the greasiness of topical applications, poor skin permeability, low skin retention, and lack of controlled delivery. To overcome these challenges, the study introduces CPM in the form of nanosuspensions (NSs), characterized by an average particle size of 211 ± 2 nm. These CPM NSs are then incorporated into a trilayer dissolving microneedle patch (MAP) made from poly(vinylpyrrolidone) and w poly(vinyl alcohol) as needle arrays and prefrom 3D printed polylactic acid backing layer. This MAP features rapidly dissolving tips and exhibits good mechanical properties and insertion capability with delivery efficiency compared to the conventional Daivonex ointment. The effectiveness of this novel MAP was tested on Sprague-Dawley rats with imiquimod-induced psoriasis, demonstrating efficacy comparable to the marketed ointment. This innovative trilayer dissolving MAP represents a promising new local delivery system for calcipotriol, potentially revolutionizing psoriasis treatment by enhancing drug delivery and patient compliance.

Genetic Diversity and Natural Selection of Plasmodium vivax Merozoite Surface Protein 8 in Global Populations

Plasmodium vivax Merozoite Surface Protein 8 (PvMSP8) is a promising candidate target for the development of multi-component vaccines. Therefore, determining the genetic variation pattern of Pvmsp8 is essential in providing a reference for the rational design of the P. vivax malaria vaccines. This study delves into the genetic characteristics of the Pvmsp8 gene, specifically focusing on samples from the China-Myanmar border (CMB) region, and contrasts these findings with broader global patterns. The study uncovers that Pvmsp8 exhibits a notable level of conservation across different populations, with limited polymorphisms and relatively low nucleotide diversity (0.00023–0.00120). This conservation contrasts starkly with the high polymorphisms found in other P. vivax antigens such as Pvmsp1. A total of 25 haplotypes and 14 amino acid mutation sites were identified in the global populations, and all mutation sites were confined to non-functional regions. The study also notes that most CMB Pvmsp8 haplotypes are shared among Burmese, Cambodian, Thai, and Vietnamese populations, indicating less geographical variance, but differ notably from those found in Pacific island regions or the Panama. The findings underscore the importance of considering regional genetic diversity in P. vivax when developing targeted malaria vaccines. Non departure from neutral evolution were found by Tajima's D test, however, statistically significant differences were observed between the kn/ks rates. The study's findings are crucial in understanding the evolution and population structure of the Pvmsp8 gene, particularly during regional malaria elimination efforts. The highly conserved nature of Pvmsp8, combined with the lack of mutations in its functional domain, presents it as a promising candidate for developing a broad and effective P. vivax vaccine. This research thus lays a foundation for the rational development of multivalent malaria vaccines targeting this genetically stable antigen.
