    BACKGROUND: Patients' sociodemographic factors, clinical characteristics, distress factors, perceived shame and stigma may give rise to psychological distress in cancer patients that bring about further psychosocial impact.

    AIMS: (1) to determine the degrees of shame and stigma towards cancer and psychological distress among cancer patients in Malaysia and (2) to examine the clinical and psychosocial predictors of psychological distress.

    METHODS: This cross-sectional study recruited a total of 217 cancer patients. The participants were administered the sociodemographic and clinical characteristics questionnaires, the Malay version of the Shame and Stigma Scale (SSS-M) to assess for the degree of cancer shame and stigma, and the Malay version of the Distress Thermometer and Problem List to assess for presence of psychological distress and identify its sources.

    RESULTS: There was a significant level of shame and stigma among cancer patients with the total mean SSS-M score of 12.08 (SD = 6.09). Anger (adjusted odds ratio [AOR] = 11.97, 95% confidence interval [CI] = 2.96-86.8, p = 0.001), loss of interest or enjoyment (AOR = 14.84, 95% CI = 2.93-75.20, p = 0.001), loneliness (AOR = 8.10, 95% CI = 1.13-58.02, p = 0.001), feeling of worthlessness or being a burden (AOR = 6.24, 95% CI = 1.32-29.59, p = 0.021), fear (AOR = 4.52, 95% CI = 1.79-11.43, p = 0.001), pain (AOR = 4.07, 95% CI = 1.53-10.82, p = 0.005), financial constraint (AOR = 2.95, 95% CI = 1.22-7.13, p = 0.016), and having regret (AOR = 1.89, 95% CI = 1.03-3.79, p = 0.039) increased the odds of developing psychological distress.

    CONCLUSION: Treating clinicians should monitor for and provide psychosocial interventions for the biopsychosocial factors which may worsen psychological distress among cancer patients.

    The human body contains trillions of cells, classified into specific cell types, with diverse morphologies and functions. In addition, cells of the same type can assume different states within an individual's body during their lifetime. Understanding the complexities of the proteome in the context of a human organism and its many potential states is a necessary requirement to understanding human biology, but these complexities can neither be predicted from the genome, nor have they been systematically measurable with available technologies. Recent advances in proteomic technology and computational sciences now provide opportunities to investigate the intricate biology of the human body at unprecedented resolution and scale. Here we introduce a big-science endeavour called π-HuB (proteomic navigator of the human body). The aim of the π-HuB project is to (1) generate and harness multimodality proteomic datasets to enhance our understanding of human biology; (2) facilitate disease risk assessment and diagnosis; (3) uncover new drug targets; (4) optimize appropriate therapeutic strategies; and (5) enable intelligent healthcare, thereby ushering in a new era of proteomics-driven phronesis medicine. This ambitious mission will be implemented by an international collaborative force of multidisciplinary research teams worldwide across academic, industrial and government sectors.

    The present study examined the vascular effects of peppermint or mint (Mentha longifolia L.) using an abdominal aortic rings model. Concentration-response curves for mint oil were generated after precontracting isolated mouse aorta with phenylephrine. The effect of different receptor antagonists and ion channel or enzyme inhibitors on the vasorelaxant potential of mint oil were studied. Molecular docking studies were conducted using computational techniques to investigate the potential interactions between the bioactive constituents of mint oil and key vascular targets. The tension of aortic rings, which had been contracted by phenylephrine, relaxed as a function of the concentration of mint oil (0.0002-2 mg/mL). Pretreatment of the rings with the nitric oxide synthase inhibitor (L-NAME), a nonselective β-blocker (propranolol), and a muscarinic receptor blocker (atropine) didn't show significant resistance to the vasodilatory effects of the mint oil. The vasodilatory effects of mint oil were significantly diminished when the rings were pretreated with glibenclamide, an inhibitor of ATP-sensitive K+ channels. In addition, indomethacin, a cyclooxygenase (COX) inhibitor, did influence mint oil's tension in the preparations precontracted with phenylephrine. The present findings imply that ATP-sensitive K+ channels activation, blocking of Ca2+ channels, and inhibition of COX play a role in mediating the mint oil-induced vasorelaxation. Molecular docking studies of mint oil constituents showed that β-Elemene and Aromadendrene can interact with K+ and Ca2+ channels through various hydrophobic interactions with key amino acid residues. Additional work is needed to confirm the possible beneficial application of mint oil or its constituents in regulating the vascular tone.

    Developing bifunctional electrocatalysts from earth-abundant first-row transition metals for large-scale hydrogen production through water electrolysis is both promising and challenging. This study presents a ternary layered double hydroxide (LDH) as a bifunctional electrocatalyst for the hydrogen evolution reaction (HER) and benzyl alcohol oxidation (BAOR). The synergy between 2D NiFeCo LDH and non-Ti-based Nb2CTx MXene enhances electrochemical performance. The electrocatalyst achieves excellent results with a low potential of 1.5 V versus RHE at 100 mA cm⁻2 for BAOR, an overpotential of 320 mV at 50 mA cm⁻2 for HER, and stability over 100 h. A solar cell-powered HER||BAOR system shows faradaic efficiency of ≈73.92% for benzaldehyde production and solar-to-hydrogen (STH) efficiency of ≈39.67%. In situ Raman analysis identifies the oxyhydroxide group as the real catalytic active site during BAOR. These findings offer valuable insights for linking fundamental research with technological innovation to address global challenges.

    This paper reports on batch investigations utilizing activated carbon (AC) made from waste Styrofoam to adsorb aluminum (Al3+) from aqueous solutions. The AC morphology and structure were examined using Fourier-transform infrared spectroscopy, scanning electron microscopy, and surface area analysis. The factors affecting the performance of adsorption were thoroughly examined. Al3+ removal was found to be maximal, that is, 98.65% using 0.2 g of AC at 90 min in a solution of pH 5 maintained at 60°C. Using a flame-mode atomic absorption spectrophotometer (AAnalyst 700, PerkinElmer, USA), the quantity of Al3+ in the adsorption solution was measured. For the purpose of studying adsorption, the pseudo-first-order, pseudo-second-order, Langmuir, Freundlich, Temkin, Jovanovich, and Harkins-Jura isotherms were analyzed. The kinetic study shows that the adsorption of Al3+ onto Al3+ is controlled by pseudo-second-order kinetics. It was observed that among these models, the Langmuir model showed the most favorable fit for the equilibrium data on the removal of Al3+ onto AC, with a strong fit (R2 = 0.995). The values of thermodynamic parameters such as entropy (ΔS°), Gibbs free energy (ΔG°), and enthalpy (ΔH°) show that the adsorption process is spontaneous and exothermic in nature. In Al3+ solutions with low concentrations, the AC exhibited a high adsorption rate. In addition, a check of the error function was performed. To find out if the AC could be utilized again after the adsorption procedure, desorption investigations were carried out. Due to its high adsorption capacity (> 98%) and porous structure, the prepared AC shows significant promise as an alternative adsorbent for Al3+. These findings demonstrate that the AC is both effective and efficient in removing Al3+ from wastewater.

    This study examines research on maqāṣid al-shariī'ah in journals indexed in Web of Science (WoS) and Scopus. As maqāṣid al-shariī'ah plays a vital role in guiding Islamic legal theory and contemporary applications of Islamic law in various sectors of life, familiarity with the scholarly landscape of the field is essential for assessing its growing influence in both academic and practical contexts. Hence, this study aims to explore the trajectory of research in maqāṣid studies, identify its key focus areas, and conduct a document co-citation analysis to uncover patterns in scholarly collaboration and influence. In addition, the study examines contributing countries, organizations, and leading journals in this field. Four Hundred documents published between 2000 and 2022 were retrieved and analyzed using the metrics functionalities of both databases. In addition, advanced analytical tools including Publish or Perish, VOSviewer, and ScientoPy v1.3.5 were utilized to conduct a multifaceted examination that encompasses document co-citation, sources co-citation, and authors' keyword analyses, among others. Data were carefully filtered to include research related to maqāṣid al-shariī'ah as an area of applied Islamic thought and its applications in different disciplines. The findings of the study revealed that research outputs in maqāṣid al-shariī'ah studies span various disciplines including religion, business and economics, science and technology, and medicine among others. The development of publications between 2000 and 2022 for the two databases indicates distinct upward trends in cumulative publications and annual growth. A vibrant and diverse global research landscape exists for maqāṣid al-shariī'ah, with Malaysia and Indonesia leading in terms of productivity and impact. This article presents original findings which may be of significance to researchers in Islamic studies, applied Islamic thought, and related interdisciplinary and multidisciplinary fields. This scientometric study is limited to English journal articles that were published between 2000 and 2022 on maqasid research in Scopus and Web of Science (WoS). Given the dynamic nature of these two databases, where results can fluctuate rapidly due to the continuous addition of new papers or the retraction of existing articles, this study is limited to the datasets that were created at the time of investigation. These limitations might influence the generalizability of the findings.

    Vanadium oxide-based compounds have attracted significant interest as battery materials, especially in aqueous Zn-ion batteries, due to favorable properties and compatibility in Zn-ion systems. In a simple hydrothermal method with moderate conditions, a novel vanadium oxide compound has been synthesized using ammonium metavanadate with oxalic acid as a reducing agent. Various characterization techniques confirmed the formation of layered V3O8(H3O)2 nanoplatelets with a tetragonal crystal structure. The as-prepared cathode material was tested in coin cells against a Zn metal anode in two aqueous electrolytes of the same concentration: ZnSO4·7H2O and Zn(CF3SO3)2. Electrochemical results showed high reversibility of Zn insertion/de-insertion and impressive cycling stability with aqueous Zn(CF3SO3)2 electrolyte. Notably, the cathode material delivered a specific capacity of 150 mA h g-1 at 100 mA g-1 and a relatively constant coulombic efficiency near 100%, indicating impressive stability during cycling and reversibility of charge/discharge electrochemical reactions. Post-mortem characterization exposed a significant structural change in the as-prepared cathode material from nanoplatelets to nanoflakes after full discharge, which reverted to nanoplatelets after charging, reflecting the high level of reversibility of the material. DFT calculations revealed a structural change in the material after cycling, providing mechanistic insights in Zn2+-ion storage.

    Cellular mesenchymal-epithelial transition factor (c-MET), also known as hepatocyte growth factor receptor (HGFR), is a crucial receptor tyrosine kinase implicated in various solid tumors, including lung, breast, and liver cancers. The concomitant expression of c-MET and PD-L1 in tumors, such as hepatocellular carcinoma, highlights their prognostic significance and connection to therapeutic resistance. Cancer-associated fibroblasts and mesenchymal stromal cells produce hepatocyte growth factor (HGF), activating c-MET signaling in tumor cells and myeloid-derived suppressor cells (MDSC). This activation leads to metabolic reprogramming and increased activity of enzymes like glutaminase (GLS), indoleamine 2,3-dioxygenase (IDO), and arginase 1 (ARG1), depleting essential amino acids in the tumor microenvironment that are vital for effector immune cell function. This review highlights the interplay between tumor cells and myeloid-derived suppressor cells (MDSCs) that create an immunosuppressive environment while providing targets for c-MET-focused immunotherapy. It emphasizes the clinical implications of c-MET inhibition on the behavior of immune cells such as neutrophils, macrophages, T cells, and NK cells. It explores the potential of c-MET antagonism combined with immunotherapeutic strategies to enhance cancer treatment paradigms. This review also discusses the innovative cancer immunotherapies targeting c-MET, including chimeric antigen receptor (CAR) therapies, monoclonal antibodies, and antibody-drug conjugates, while encouraging the development of a comprehensive strategy that simultaneously tackles immune evasion and enhances anti-tumor efficacy further to improve the clinical prognoses for patients with c-MET-positive malignancies. Despite the challenges and variability in efficacy across different cancer subtypes, continued research into the molecular mechanisms and the development of innovative therapeutic strategies will be crucial.

    INTRODUCTION: Vaccine hesitancy poses a threat to the prevention of COVID-19 and other vaccine-controlled diseases. In 2019, the Government of Trinidad and Tobago launched a policy outlining the scope of health services in the public sector available to registered Venezuelan migrants to include access to routine immunizations. Little is understood about immunization uptake among migrants, including the uptake of COVID-19 vaccinations in Trinidad and Tobago.

    METHOD: Between July and October 2022, a survey was conducted using a sample of n = 507 Venezuelan migrants. We examined the relationship between COVID-19 vaccine hesitancy, migrant's attitudes toward past vaccinations, their beliefs and perceptions about COVID-19 disease, and health-service related factors. Descriptive statistics summarized the characteristics of these migrants. Odds ratios with 95% confidence intervals and multivariable logistic regression was used to examine factors and attitudes associated with COVID-19 vaccine hesitancy.

    RESULTS: Our findings showed that 89% of the migrants accessed publicly available health services while in Trinidad and Tobago, 72.4% reported that they did not refuse other vaccines in the past, and 23% reported being hesitant to take the COVID-19 vaccine. Females had higher odds of being COVID-19 vaccine hesitant compared to males, and participants expressing doubts about the source of vaccine information also had greater odds of vaccine hesitancy. Long waiting times at a public health clinic and costs associated with traveling to a clinic were associated with higher odds of COVID-19 vaccine hesitancy.

    CONCLUSION: A National Immunization Policy inclusive of the unmet needs of vulnerable migrant populations is needed to ensure equitable access to vaccinations.

    PURPOSE: Antimicrobial resistance is a global health crisis exacerbated by excessive and inappropriate use of antibiotics, especially among low- and middle-income countries including Pakistan. The paediatric population is a key area in view of their vulnerability and excessive prescribing of antibiotics in Pakistan. Consequently, there is an urgent need to robustly assess antimicrobial use among hospitalized neonates and children in tertiary hospitals in Pakistan as they are generally the training centres for new physicians subsequently treating children.

    PATIENTS AND METHODS: A point prevalence survey (PPS) was conducted in the children's wards of 14 tertiary care hospitals in Punjab Province, covering over 50% of the population of Pakistan. This builds on a previous PPS among tertiary care hospitals treating exclusively neonates and children.

    RESULTS: A total of 1811 neonates and children were surveyed with 1744 patients prescribed antibiotics, a prevalence of 96.3%. A total of 2747 antibiotics were prescribed to these 1744 neonates and children, averaging 1.57 antibiotics per patient. Overall, 57.7% of the patients were prescribed one antibiotic and 27.2% two antibiotics, with 85.6% of antibiotics administered parenterally. Over a third (34.4%) of the antibiotics were prescribed prophylactically, with 44.7% of them for surgical procedures. Among those prescribed antibiotics for surgical procedures, 75.2% were prescribed for more than one day. Overall, 92.2% of antibiotics were prescribed empirically, with 86.2% prescribed without mentioning the rationale for their choice in the notes, with 77.6% having no stop date. Respiratory tract infections were the most common indication (43.4%). Staphylococcus species (36.0%) were the most common pathogen with limited Culture and Sensitivity Testing performed. Three quarters (75.2%) of antibiotics were from the Watch list, and 24.4% were Access antibiotics.

    CONCLUSION: A very high prevalence of antibiotic use among neonates and children in tertiary hospitals in Pakistan, including Watch antibiotics, mirroring previous studies. Consequently, initiatives including antimicrobial stewardship programmes are urgently needed to address current inappropriate prescribing.

    The bovine leukocyte antigen (BoLA) gene is a significant genetic part of the immune system and has been used as a disease marker in cattle. In this study, we detected Theileria orientalis, T. sinensis, Anaplasma marginale, Anaplasma platys, Candidatus Mycoplasma haemobos and Trypanosoma evansi by PCR amplification and sequencing of the amplicons. The allelic association of the BoLA-DRB3.2 gene with blood pathogen disease resistance and susceptibility in 87 Kedah-Kelantan x Brahman (KKB) and 38 Bali cattle was determined by Fisher's exact test and Cochran Mantel Haenszel (CMH) correction test. Sequence-based typing of the BoLA-DRB3.2 gene identified 43 alleles (27 previously reported alleles and 16 novel alleles) across the two cattle breeds. Alignment analysis of the 16 novel alleles revealed 90.7-95.8% and 85-92% nucleotide and amino acid identities, with the reference allele, BoLA-DRB3*016:01 cDNA clone NR-1. BoLA-DRB3*009:02 (25.6%) and BoLA-DRB3*036:01 (36%) were the most frequent alleles in KKB and Bali cattle, respectively. In KKB cattle, BoLA-DRB3*020:02:01 was significantly associated with resistance to T. orientalis whereas *007:01 and *009:02 were significantly associated with resistance to C. Mycoplasma haemobos. Also, DRB3*017:01 was associated with susceptibility to T. orientalis in KKB cattle. In the Bali cattle, BoLA-DRB3*015:01 was found to be a genetic marker of susceptibility to C. Mycoplasma haemobos infection. Therefore, this study identified BoLA-DRB3.2 alleles associated with resistance and susceptibility to T. orientalis infection in KKB cattle and susceptibility to C. Mycoplasma haemobos infection in Bali cattle for the first time. Therefore, this study suggests that these BoLA-DRB3 resistance alleles could be used as candidate markers for selection, whereas susceptibility alleles could be used as candidate markers for culling in the beef industry.

    This study aimed to evaluate the effects of substituting a crude palm oil (CPO) diet with palm-pressed fibre oil (PPFO) on laying hens' performance, egg production, carcass characteristic and egg quality. A total of 150 Hisex Brown laying hens were randomly assigned to five treatments: a basal diet containing 4% CPO (T1-control) and basal diets in which CPO was substituted by 25% (T2), 50% (T3), 75% (T4) or 100% (T5) PPFO. These diets were fed to laying hens ad libitum for 16 weeks. Compared to the T1 diet, dietary treatments T2, T3 and T4 had no significant effect (P > 0.05) on the feed intake, body weight gain, feed conversion ratio, egg number, egg production, egg weight and egg mass of the laying hens during the entire experimental period. Nonetheless, a significant (P

    The efficacy and safety of rituximab in childhood steroid-resistant nephrotic syndrome (SRNS) remains unclear. Therefore, we conducted a retrospective cohort study at 28 pediatric nephrology centers from 19 countries in Asia, Europe, North America and Oceania to evaluate this. Children with SRNS treated with rituximab were analyzed according to the duration of calcineurin inhibitors (CNIs) treatment before rituximab [6 months or more (CNI-resistant) and under 6 months]. Primary outcome was complete/partial remission (CR/PR) as defined by IPNA/KDIGO guidelines. Secondary outcomes included kidney failure and adverse events. Two-hundred-forty-six children (mean age, 6.9 years; 136 boys; 57% focal segmental glomerulosclerosis, FSGS) were followed a median of 32.4 months after rituximab. All patients were in non-remission before rituximab. (146 and 100 children received CNIs for 6 month or more or under 6 months before rituximab, respectively). In patients with CNI-resistant SRNS, the remission rates (CR/PR) at 3-, 6-, 12- and 24-months were 26% (95% confidence interval 19.3-34.1), 35.6% (28.0-44.0), 35.1% (27.2-43.8) and 39.1% (29.2-49.9), respectively. Twenty-five patients were in PR at 12-months, of which 22 had over 50% reduction in proteinuria from baseline. The remission rates among children treated with CNIs under 6 months before rituximab were 42% (32.3-52.3), 52% (41.8-62.0), 54% (44.3-64.5) and 60% (47.6-71.3) at 3-, 6-, 12-, and 24-months. Upon Kaplan-Meier analysis, non-remission and PR at 12-months after rituximab, compared to CR, were associated with significantly worse kidney survival. Adverse events occurred in 30.5% and most were mild. Thus, rituximab enhances remission in a subset of children with SRNS, is generally safe and CR following rituximab is associated with favorable kidney outcome.

    BACKGROUND: Bismuth quadruple therapies (BQTs) including bismuth, a proton pump inhibitor (PPI) and two antibiotics have been shown to be highly effective for treating Helicobacter pylori infection even in areas of high bacterial antibiotic resistance.

    OBJECTIVE: To describe the time trends of use, effectiveness and safety of BQT in Europe using the European Registry on Helicobacter pylori Management (Hp-EuReg).

    DESIGN: Patients registered in the Hp-EuReg from 2013 to 2021 who had received BQT were included. The regimens prescribed, the number of eradication attempts, effectiveness, adherence and safety were analysed. The effectiveness was assessed by modified intention to treat (mITT). Time-trend and multivariate analyses were performed to determine variables that predicted treatment success.

    RESULTS: Of the 49 690 patients included in the Hp-EuReg, 15 582 (31%) had received BQT. BQT use increased from 8.6% of all treatments in 2013 to 39% in 2021. Single-capsule BQT-containing bismuth, metronidazole and tetracycline-plus a PPI (single-capsule BQT, ScBQT) was the most frequent treatment mode (43%). Schemes that obtained an effectiveness above 90% were the 10-day ScBQT and 14-day BQT using tetracycline plus metronidazole, or amoxicillin plus either clarithromycin or metronidazole. Only ScBQT achieved above 90% cure rates in all the geographical areas studied. Using the ScBQT scheme, adherence, the use of standard or high-dose PPIs, 14-day prescriptions and the use of BQT as first-line treatment were significantly associated with higher mITT effectiveness.

    CONCLUSION: The use of BQT increased notably in Europe over the study period. A 10-day ScBQT was the scheme that most consistently achieved optimal effectiveness.

    The objective of this study is to comprehensively characterize persistent organic pollutants (POPs) in seawater at Kaohsiung Harbor, focusing on their concentrations, partitioning behaviors, and profiles in both particle and liquid phases. We analyzed 100 L seawater for each sample, finding total dioxin-like toxicity (PCDD/Fs + PCBs + PBDD/Fs) ranging from 0.00936 to 0.167 pg WHO-TEQ/L, with PCDD/Fs accounting for 68 % of total toxicity. POPs predominantly appeared in the particle phase, observed in over 80 % of samples, except for PCBs. The observed correlations between particulate matter (PM) and chlorinated POPs at sites receiving river effluents suggest shared pollution sources. The liquid partition of PCDD/Fs, PCBs, and PBDEs in the seawater shows an inverse relationship with log Kow and a direct proportionality with solubility, particularly above 0.1 μg/L. Furthermore, PBDEs in seawater can transform into PBDD/Fs upon UV light exposure, highlighting another potential pathway for the persistence and spread of these harmful contaminants in the environment. These findings emphasize the need for field-based investigations to assess PBDF formation in aquatic environments and underscore the importance of stronger mitigation strategies, including better wastewater treatment and stricter discharge regulations to reduce POPs in marine ecosystems.

    Magnesium stearate (MgSt) is a common tablet lubricant. As variations in MgSt properties are known to influence tablet attributes, the impact of MgSt fatty acid composition, particularly the significance of the stearate and palmitate contents, and its effects on tablet properties warrant further investigation. This study investigated the effect of MgSt with different stearate and palmitate contents but comparable physical properties (e.g. particle size, crystallinity, specific surface area and morphology) on lubrication performance and resulting tablet quality attributes, including mechanical strength, disintegratability and drug release. The influence of MgSt concentration and blending duration on the resulting tablet properties was also examined. Tablets produced using the lower stearate content MgSt had slightly higher tensile strength. The effect of MgSt stearate content was more apparent in the disintegration time and drug release, whereby MgSt of lower stearate content resulted in tablets with longer disintegration time and slower drug release. The lower stearate content also resulted in a lower lubrication performance, leading to a lesser reduction in tablet ejection force. As expected, a longer blending time of the tablet formulation blend with MgSt yielded tablets with reduced tensile strength, shorter disintegration time and slower drug release. Tablets with higher MgSt concentration showed a greater reduction in tensile strength, longer disintegration time and faster drug release. The study findings reinforced observations by other researchers and provided a better understanding of the fatty acid composition effects of MgSt on lubrication performance and the resulting tablet properties.
