    BACKGROUND: Cannabis is the third most widely used psychoactive substance globally, and its consumption has been increasing, particularly with the growing trend of legalization for medicinal and recreational use. Recent studies have raised concerns about the potential impact of cannabis on respiratory health, specifically the risk of asthma, a significant public health concern. This systematic review aimed to consolidate research on the association between cannabis use and the risk of asthma.

    METHODS: A comprehensive search was conducted across PubMed, Embase, and Web of Science, covering studies published up to September 30, 2024. We included peer-reviewed observational studies evaluating the link between cannabis consumption and the risk of asthma diagnosis. Data synthesis employed a random-effects meta-analysis to account for heterogeneity. R statistical software (version 4.4) was used for statistical analyses.

    RESULTS: The search yielded 8 relevant studies after screening 1,887 records. The pooled odds ratio (OR) for the association between cannabis consumption and the risk of asthma diagnosis was 1.31, 95% confidence interval (CI): 1.19-1.44, indicating greater odds of having asthma compared to non-users. Moderate heterogeneity was observed (I² = 46%), and sensitivity analysis confirmed the robustness of the findings.

    CONCLUSION: This systematic review and meta-analysis identifies a significant association between cannabis use and greater odds of having asthma. These findings emphasize the importance of raising awareness about the potential respiratory risks associated with cannabis use. Future research should prioritize identifying moderating factors, such as the frequency and mode of cannabis consumption, to enhance understanding of this association and provide a stronger evidence base for potential public health interventions.

    BACKGROUND: Proton pump inhibitors (PPIs) are commonly used for managing gastroesophageal disorders but concerns about their potential association with increased stroke risk have emerged, especially among patients with pre-existing cardiovascular conditions such as acute coronary syndrome (ACS). This systematic review and meta-analysis aim to assess the risk of stroke associated with PPI use, stratified by the presence or absence of pre-existing CVD.

    METHODS: This review was conducted following the PRISMA guidelines and included studies up to March 2024 from PubMed, Embase, and Web of Science. Eligible studies were longitudinal, including prospective cohorts, nested case-controls, and post-hoc analyses of RCTs that reported stroke outcomes in relation to PPI use. Data were synthesized using random-effects meta-analysis models in R software version 4.3.

    RESULTS: Our search yielded 41 studies encompassing over 800,000 participants globally. Meta-analysis of 14 observational studies revealed a slight but non-significant increased stroke risk among patients with prior CVD (pooled HR = 1.222, 95% CI: 0.963 to 1.481, I² = 78%). In contrast, analysis of 15 studies without prior CVD showed a modestly increased risk (pooled HR = 1.15, 95% CI: 1.023 to 1.288, I² = 98%). Five RCTs involving patients with CVD reported a pooled RR of 1.158 (95% CI: 0.914 to 1.466), indicating no significant risk increase.

    CONCLUSION: The association between PPI use and stroke risk appears modest and is influenced by the presence of cardiovascular conditions. Clinical decision-making should consider individual patient risk profiles, and further high-quality studies are needed to guide safer PPI prescribing practices.

    In the Johor River Basin, a comprehensive analysis was conducted on 24 water environmental parameters across 33 sampling sites over 3 years, encompassing both dry and wet seasons. A total of 396 water samples were collected and analyzed to calculate the Water Quality Index (WQI). To further assess water quality and pinpoint potential pollution sources, multivariate techniques such as principal component analysis (PCA) and cluster analysis (CA), alongside spatial analysis using inverse distance weighted (IDW) interpolation, were employed. According to the National Water Quality Standard, most of the analyzed physicochemical components fall within Classes II and III, albeit with varying concentrations. However, certain sites exhibited levels of BOD5, TSS, and nutrients such as total nitrogen (TN) and total phosphorus (TP) that exceeded the threshold level of water quality standards, signaling pollution from diverse sources. Notably, all trace elements, with the exception of copper (Cu) and nickel (Ni), remained within the acceptable limits set by WHO guidelines and the National Water Quality Standard. PCA revealed parameter groupings linked to factors such as soil erosion, salinity, wastewater discharge, and fecal contamination, which are key determinants of water quality. The cluster analysis categorized the 33 sampling sites into three distinct clusters, each reflecting the geological setting and varying levels of pollution. The IDW-based spatial distribution indicated significant water quality degradation as the river flows downstream, particularly in regions experiencing rapid agricultural, industrial, and residential development. These activities contribute to the breakdown of organic matter and the release or overflow of wastewater into nearby river systems. This study highlights the effectiveness of integrating data-driven methodologies for surface water quality assessment, offering valuable insights for sustainable watershed management.

    Malachite Green (MG) is an antibiotic with antifungal activity, which is illegal to use in agriculture due to its mutagenic and teratogenic properties. Several scientific papers have been published on MG in fish. Therefore, an attempt was made to determine the meta-analysis concentration of MG in fish based on countries and types of fish subgroups, as well as the health risks of consumers, using the Monte Carlo simulation (MCS) model. The three countries with the highest concentration of MG were Iran (14.697 µg/kg), Brazil (2.840 µg/kg), and China (2.277 µg/kg). The overall pooled concentration of MG in fish was 3.036 µg/kg, 95%CI (2.860-3.212 µg/kg), and the highest concentration of MG was observed in Pacu fish (6.603 µg/kg). The health risk assessment shows adults in Malaysia, China, and Iran and children in Italy, Spain, Brazil, Malaysia, China, and Iran are at considerable risk (MOE <10,000); hence, carrying out control plans in these countries is recommended.

    The reason why certain bacteria, e.g., Pseudomonas aeruginosa (PA), produce acetylated alginate (Alg) in their biofilms remains one of the most intriguing facts in microbiology. Being the main structural component of the secreted biofilm, like the one formed in the lungs of cystic fibrosis (CF) patients, Alg plays a crucial role in protecting the bacteria from environmental stress and potential threats. Nonetheless, to investigate the PA biofilm environment and its lack of susceptibility to antibiotic treatment, the currently developed in vitro biofilm models use native seaweed Alg, which is a non-acetylated Alg. The role of the acetyl side group on the backbone of bacterial Alg has never been elucidated, and the transposition of experimental results obtained from such systems to clinical conditions (e.g., to treat CF-infection) may be hazardous. We systematically investigated the influence of acetylation on the physico-chemical and mechanical properties of Alg in solution and Ca2+-crosslinked hydrogels. Furthermore, we assessed how the acetylation influenced the interaction of Alg with tobramycin, a common aminoglycoside antibiotic for PA. Our study revealed that the degree of acetylation directly impacts the viscosity and Young's Modulus of Alg in a pH-dependent manner. Acetylation increased the mesh size in biofilm-like Alg hydrogels, directly influencing antibiotic penetration. Our results provide essential insights to create more clinically relevant in vitro infection models to test the efficacy of new drugs or to better understand the 3D microenvironment of PA biofilms.

    INTRODUCTION: Cardiovascular diseases are the leading cause of death and morbidity worldwide, with a significantly higher burden in low- and middle-income countries. Hypertension, a major risk factor for cardiovascular morbidity and mortality, remains under-diagnosed and poorly controlled, especially in regions such as Latin America. The HOPE-4 study demonstrated that the involvement of non-physician health workers (NPHWs), the use of standardized treatment algorithms, the provision of free antihypertensive drugs and home follow-up can significantly improve hypertension control and reduce cardiovascular risk, as demonstrated in Colombia and Malaysia. On this basis, the COTRACO study aims to address the barriers to hypertension treatment in low- and middle-income countries by implementing a similar standardized treatment approach delivered by non-specialist health workers.

    METHODOLOGY: The COTRACO study is a quasi-experimental, parallel-group, non-randomized, before-and-after study. A community-based model will be implemented in 600 patients in Colombia and the Dominican Republic, involving NPHWs to: 1) apply standardized treatment algorithms, 2) promote adherence to healthy lifestyles, and 3) provide standardized pharmacological treatment. Propensity Score Matching will be used to select 300 patients in Chile and 1200 in Spain for comparison with standard care in these populations.

    EXPECTED OUTCOMES: The primary outcome at 12 months of follow-up is the percentage of patients achieving controlled hypertension (defined as systolic BP

    This paper sheds light on how spaces become contested sites for identity construction and negotiation to take place. Applying the Social Representations Approach, a qualitative study of 10 focus group discussions (n = 39), was conducted in Singapore, Malaysia and the UK to explore how, and why racialised identity construction changed in each socio-political context. The study challenged two underlying assumptions in social psychology: (1) that the meaning of the racialised category holds constant across time and space, and (2) there exists a pan-racial identification among Asian identities, for example, which at times allows for racialised categories to be manipulated as variables. We argue that the distinction between the country that the racialised identity originates from, country of birth (or citizenship) for the individual and country that the individual manages the identity in, is important in understanding the changes in the psychology of racialised identities. By taking into consideration the interplay of temporality, space, social relations and social systems, this paper presents a contribution in the form of the concept "politicized psycho-geographies".

    INTRODUCTION: The synergistic combination of histone deacetylase inhibitors and platinum-based medicines represents a promising therapeutic strategy to efficacy and overcome drug resistance in cancer therapy, necessitating a comprehensive understanding on their molecular interactions and clinical potential.

    AREAS COVERED: The objective of presented review is to investigate the molecular pathways of platinum medicines and HDAC inhibitors. A comprehensive literature review from 2011 to 2024 was conducted across multiple databases like MEDLINE, PubMed, Google Scholar, Science Direct, Scopus and official websites of ClinicalTrial.gov to explore publications on HDAC inhibitors, platinum drugs, and combination cancer therapies, revealing preliminary evidence of innovative treatment strategies involving HDAC inhibitors and platinum chemotherapeutics. Several new platinum (IV) complexes, with HDAC inhibitory moieties and better cytotoxicity profiles than conventional platinum drugs, are also reviewed here.

    EXPERT OPINION: The above combination has great potential in cancer treatment, however managing toxicity, dosage regimens, and patient selection biomarkers are problematic. More selective HDAC inhibitors and innovative delivery techniques are potential areas for future research. An adaptation toward changing cancer therapeutic landscapes, highlights combining HDAC inhibitors with platinum-based medicines serves as a new concept for personalized medicine, however, a deeper research is still needed at this time.

    INTRODUCTION: The advancements in neonatal resuscitation and surgical care have enabled children with congenital abnormalities to receive corrective surgeries and achieve lifespans well into adulthood. These patients may require long-term follow-up as they continue to have risks of developing sequelae from their original diseases or surgical interventions.

    PURPOSE: This study aimed to investigate the current practice and barriers to the transition of care (TOC) from the perspectives of adult surgeons.

    METHODS: A cross-sectional study was conducted with purposive sampling of adult surgeons from different subspecialties. An online self-administered questionnaire was distributed.

    RESULTS: There were 60 respondents. 62% of the respondents had experience managing referrals for continuation of care or complications in patients with congenital abnormalities. 38% of the respondents believed that TOC should be implemented when patients reached ages 17-18 years. 93% of the respondents agreed that a proper TOC model would greatly benefit patient care, and 97% asserted the need to develop TOC pathways in Malaysia. The absence of a proper guideline was the greatest barrier to a smooth TOC.

    CONCLUSION: This study offered insights into the obstacles to TOC based on the perspectives and experiences of adult surgeons who participated. While not exhaustive, our study provided a better understanding of the challenges in developing the appropriate referral pathways for the continued care of these patients.

    The nutria (Myocastor coypus) is a semiaquatic rodent that originally inhabited South America. However, the animals have spread to different continents as alien species, and their numbers are quickly increasing, especially in North America, Europe, and Eastern Asia including Japan. Although nutrias have been suggested to serve as reservoirs for pathogens, including parasites, there have been few reports on this subject. In the present study, we surveyed the gastrointestinal parasites in nutrias living in Japan to better understand their prevalence in nutrias. We collected 72 samples of intestinal contents or feces from nutrias in Osaka and Okayama Prefectures. We found that 49 (68.1 %) samples were positive for Eimeria parasites, and two types of oocysts were identified: ellipsoidal (Type A) and subspherical (Type B) oocysts. In addition, Strongyloides myopotami was detected in 44 samples, and Capillaria spp. and Fasciola spp. were detected in one and three samples, respectively. Based on the morphologies of the detected Eimeria oocysts, Types A and B were identified to be E. coypi and E. fluviatilis, respectively. Phylogenetic analyses after PCR and sequencing targeting the cytochrome c oxidase subunit I gene placed the sequences of E. fluviatilis (Type B) as a cluster between the sequences of Eimeria derived from rodents. The sequences of the three subgenotypes of E. coypi (Type A) were included in the cluster containing the sequences of Eimeria spp. from rodents of multiple species, which is referred to as the Apionodes supercluster, and is separate from other clades. It has been suggested that Eimeria spp. from rodents in this cluster can quickly adapt to infect different hosts. Although further analyses are needed to construct more detailed phylogenetic trees, our results revealed the genetical positions of Eimeria spp. in nutrias. In addition, our results may be helpful when considering host specificity as well as host switching by the pathogen.

    BACKGROUND:  The KOTAK program is a national public health initiative in Malaysian primary and secondary schools aimed at reducing youth smoking through school dental services. This study evaluated its effectiveness in Seremban, Negeri Sembilan, Malaysia.

    OBJECTIVES: 1) To determine the percentage of schoolchildren who quit smoking through the KOTAK program; 2) To identify factors associated with quitting smoking in the program.

    METHODS: A clustered, randomized controlled trial was conducted in schools. Self-reported smokers meeting inclusion criteria were enrolled. Data on demographics, self-reported smoking abstinence, and nicotine addiction levels were collected at baseline, three months, and six months post-intervention. Exhaled carbon monoxide was measured at all time points, and salivary cotinine was collected at three- and six-month follow-ups.

    RESULTS: Six months post-intervention, 29.8% of students in intervention schools and 14.6% in control schools reported quitting smoking. The odds of quitting were higher with the KOTAK program (aOR = 2.25, 95% CI = 1.11-4.57). Factors such as age, maternal education, and baseline nicotine addiction level were protective for smoking abstinence.

    CONCLUSION: The intervention group showed a higher self-reported smoking cessation rate, indicating the potential efficacy of the KOTAK program.

    INTRODUCTION: Breast cancer is the most prevalent cancer among women worldwide, and advancements in detection and treatment have improved survival rates. Evaluating breast cancer patients' quality of life is essential for effective healthcare planning. This study aims to assess the level of quality of life and its associated factors, including sociodemographic, clinical, coping skills, and psychological factors among breast cancer women in Iraq.

    METHODS: A cross-sectional study was conducted among 244 breast cancer women in The Medical City Teaching Oncology Hospital, Baghdad, Iraq, from August 2023 to October 2023. QOL, coping skills, and psychological factors were assessed using the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Group Core-30 (QLQ-C30), BRIEF COPE-28, and Hospital Anxiety and Depression Scale (HADS) scale, respectively. Sociodemographic and clinical characteristics were also assessed. The associations between the association factors and quality of life were assessed using multiple linear regression.

    RESULT: The mean (SD) quality of life scores for global, functional, and symptom domains were (53.24 ± 16.80, 46.23 ± 25.16, and 53.82 ± 22.10), respectively. Multiple linear regression analysis revealed significant factors influencing global quality of life were age, marital status, disease duration, hormonal therapy, passive coping, and anxiety. Age, disease duration, passive coping, and anxiety were significant factors for the functional domain. The symptom domain was notably affected by menstrual status, mastectomy, passive coping, and depression.

    CONCLUSION: These results provide crucial insights for developing targeted interventions to enhance the quality of life for breast cancer patients in Iraq.

    Oil fields located in cold environments and deep-sea locations often face challenges with paraffin wax buildup in pipelines during long-distance crude oil transportation. Various strategies have been employed to address this issue, with chemical methods being the most effective and economical. However, traditional chemical inhibitors present problems due to their high toxicity and low biodegradability, leading to increased operational costs and environmental concerns. This study focuses on developing an eco-friendly paraffin inhibitor system using three different concentrations of Glycine and Palm-based Methyl Ester Sulfonate (MES). Experiments were conducted on crude oil samples from the Dulang Oilfield. The experimental measurements include wax appearance temperature (WAT), pour point temperature (PPT), and rheological tests in the absence and presence of the proposed inhibitors. The results revealed that both Glycine and MES can effectively reduce WAT, viscosity, and yield point. Specifically, 10% Glycine was the best inhibitor, reducing WAT by 23.3%. However, MES (1%, 5%, and 10%) demonstrated greater overall effectiveness, with an average WAT reduction of 13.76% compared to Glycine's 10.85%. MES also shows a better performance in reducing viscosity and yield stress. While PPT results were insignificant, MES is recommended as a flow improver rather than a pour point depressant. The successful development of these newly formulated chemical inhibitors promises an environmentally sustainable and economically efficient approach to maximizing oil production from mature fields while mitigating paraffin precipitation.

    Two-dimensional Transition Metal Dichalcogenides (2D TMDs) have garnered significant attention in the field of materials science due to their remarkable electronic and optoelectronic properties, including high carrier mobility and tunable band gaps. Despite the extensive research on various TMDs, there remains a notable gap in understanding the synthesis techniques and their implications for the practical application of monolayer tungsten disulfide (WS2) in optoelectronic devices. This gap is critical, as the successful integration of WS2 into commercial technologies hinges on the development of reliable synthesis methods that ensure high quality and uniformity of the material. In this study, we present a comprehensive overview of the synthesis techniques for monolayer WS2, focusing on mechanical stripping, Atomic Layer Deposition (ALD), and Chemical Vapor Deposition (CVD). We highlight the advantages of each method, such as the uniform growth achievable with ALD at low temperatures and the capability of CVD to produce large-area, high-quality monolayers. Additionally, we summarize the performance of WS2 in various electronic and optoelectronic applications, including field-effect transistors (FETs), photodetectors, and logic devices. Our findings indicate that with ongoing advancements in film uniformity, compatibility with existing semiconductor processes, and the long-term stability of WS2-based devices, there is a promising trajectory for the transition of 2D WS2 from laboratory research to practical applications. This work not only addresses the existing gaps in the literature but also underscores the potential of WS2 to significantly impact the future of optoelectronic technologies. .

    BACKGROUND: Human papillomavirus-associated oral epithelial dysplasia (HPV-OED) has been recently recognised by the World Health Organisation (WHO) as a distinct type of oral epithelial dysplasia. The rarity of HPV-OED, together with gaps in the current understanding of risk factors and clinical behaviour raise the risk of under-recognition and misdiagnosis. To address this, we describe the clinico-pathological features of a consecutive series of HPV-OED from a single institution to provide additional insight into the presentation and behaviour of this disease.

    METHODS: Consecutive cases of HPV-OED were identified over a 20-year period from the pathology routine diagnostic archives of a single centre. Cases with features of viral cytopathic changes in a background of OED underwent HPV-specific testing in addition to p16 immunohistochemistry to confirm HPV positivity.

    RESULTS: Fifty-three consecutive patients with HPV-OED were identified. The mean age at diagnosis was 55 years-old and there was a strong male predilection (83 %). Most patients were smokers or former smokers, and almost a fifth of individuals were Human Immunodeficiency Virus (HIV)-positive. The latero-ventral tongue was the most common index site. Twenty-eight percent of cases were associated with invasive oral squamous cell carcinoma. There was a statistically significant association between with patient's HIV status and malignant transformation (p = 0.022).

    CONCLUSIONS: Findings from our cohort of HPV-OED patients suggests that malignant transformation is relatively frequent and associated with the HIV status of patients.

    Polysaccharides such as chitosan, alginate, cellulose, and carrageenan have emerged as promising adsorbents due to their biodegradability, abundant availability, and diverse chemical functionality. These biopolymers exhibit promising performance for adsorption of a wide range of pollutants including heavy metals (e.g., lead, cadmium), organic dyes (e.g., methylene blue, methyl orange), and even pathogenic microorganisms. However, inherent hydrophilicity and poor mechanical properties limit their broader application in environmental and biomedical fields. As an effective way to address the issues, recent advancements have focused on the incorporation of nanoparticles (e.g., metal oxides, carbon nanotubes and clays) into polysaccharides to obtain nanocomposite films. Generally, these nanocomposites offer enhanced surface area, tunable porous network, and improved chemical and mechanical resistances for adsorption and biomedical applications. The current review gives a focused overview of the recent progresses in polysaccharide-based nanocomposites, with particular attention to their fabrication methods, adsorption capacity and mechanism, and diverse applications in water purification, drug delivery, and antimicrobial treatments. Critical challenges such as the optimization of nanoparticle dispersion and the environmental impacts of nanocomposite biodegradation are also discussed to pave the road for the future research in this promising field.

    INTRODUCTION: This systematic review with network meta-analysis (NMA) analysed the current evidence on in vitro studies comparing trueness of fit, surface roughness, colour stability, surface wettability, water sorption, water solubility, and microbial adhesion between conventional and digital denture bases.

    METHODS: From inception until December 2023, a systematic search of published in-vitro studies from Scopus, PubMed, and the Cochrane Central Register of Controlled Studies was conducted. The protocol was registered in PROSPERO (CRD42024531416). NMA compared properties related to dimensional accuracy and surface properties between conventional and digital dentures. The ranking was performed using the surface area under the cumulative ranking guidelines.

    RESULTS: A total of 6004 articles were initially identified, of which 342 duplicates were removed, and 5566 were excluded by screening the titles and abstracts. A total of 96 articles were assessed by full-text reading, and 43 were included in the quantitative synthesis. As per the NMA results, MIL demonstrated significantly higher trueness of fit when compared with conventional compression moulding (standardized mean differences [SMD] = -2.25 [95% CI: -4.09, -0.40]), P = .017 (
