Background

Longitudinal studies provide insights into the outcomes of medical training curriculum. However, few educational cohort studies have been conducted in Iran. This study aims first to evaluate the impact of the current curriculum on medical students' medium- and long-term academic and career outcomes and, second, to identify medical students' characteristics and how they change through the doctor of medicine programme.

Methods and analysis

This protocol outlines a multi-phase, prospective cohort study that will take place in Mashhad, Iran. The study will implement the Kirkpatrick model, investigating medical students' knowledge, skills, behaviour and professionalism development over 10 years. Approximately 1000 medical students will be recruited through peer invitations and social networks. Data will be collected through baseline and follow-up questionnaires, academic performance records and comprehensive test scores throughout the Doctor of Medicine (MD) programme.

The data from the questionnaires will be reported using a Likert scale. Quantitative data will be described using means and SD, while qualitative variables will be presented as frequencies and percentages. We will evaluate the relationship between quantitative variables using correlation coefficients and the relationship between qualitative variables via the 2 or Fisher exact test. All tests will be two-sided, with a significance level set as p

Ethics and dissemination

All participants will complete written informed consent before data collection. All students can withdraw from the study at any time with no consequences. Results of this study will be presented at relevant conferences and will be submitted for publication in peer-reviewed journals. This study was approved by the Ethics Committee of Mashhad University of Medical Sciences.

Barriers to treatment adherence among patients with tuberculosis: a qualitative study of Pakistani nationals and Afghan refugees

Por: Sanauddin · N. · Ahmad · F. · Rahim · M. · Paracha · M. A. · Khan · Z. · Qazi · F. K. · Rasool · S. · Butt · M. · Naeem · F. · Khan · M. F. · Sheikh · S. · Kibria · Z. · Fonseka · N. · Ul-Haq · M. · Farooq · S. — Octubre 6th 2025 at 02:14
Objectives

Non-adherence to tuberculosis (TB) treatment remains a major challenge in high-burden regions. However, few studies have qualitatively examined the sociocultural and emotional barriers to adherence, particularly among Afghan refugees in Pakistan. This study explores the patient-related, sociocultural and treatment-related barriers to treatment adherence among patients with TB of Pakistani and Afghan origin living in Pakistan.

Design

We conducted an exploratory qualitative study consisting of semistructured focus group discussions (FGDs) and in-depth interviews (IDIs) with purposively selected multisectoral stakeholders. The data were analysed thematically using a combination of inductive and deductive approaches.

Settings

We employed a qualitative study design in the TB DOTS (Directly Observed Treatment Short course) centres in the Haripur and Peshawar districts of Khyber Pakhtunkhwa province, Pakistan.

Participants

We conducted IDIs (n=29) and FGDs (n=11) with three categories of participants: TB healthcare providers, patients with TB and their carers.

Results

We identified several contributors to lower treatment adherence. These included patient-related barriers (eg, lack of awareness about TB and its treatment), sociocultural barriers (eg, stigma, refugee status of Afghan patients, gender roles and reliance on traditional and spiritual healing) and treatment-related barriers (eg, demanding treatment regimen and TB-induced depression).

Conclusion

Several personal, sociocultural and treatment-related barriers contribute to lower treatment adherence in patients with TB. A significant contributing factor to treatment non-adherence in patients is the high prevalence of anxiety and depression related to TB and its treatment, for which there is no treatment or counselling available at the DOTS level in Pakistan, warranting the need for mental health interventions that could improve adherence and treatment outcomes for both TB and depression.

Objectives

To evaluate temporal trends in the epidemiology of hip osteoarthritis (OA) in the USA from 1990 to 2019, with stratification by sex and geographic region.

Design

Cross-sectional time-series analysis using secondary data from the Global Burden of Disease (GBD) study.

Setting

US population-based analysis, stratified by the four US Census Bureau regions: Northeast, Midwest, South and West.

Participants

De-identified, aggregate population-level data representing all adults in the USA from 1990 to 2019, drawn from the GBD database.

Primary and secondary outcome measures

Age-standardised rates per 100 000 population for years lived with disability (YLDs), prevalence and incidence of hip OA. Outcomes were stratified by sex and region. Statistical significance was defined as p

Results

Between 1990 and 2019, hip OA in the USA increased by 23.91% in YLDs, 24.67% in prevalence and 25.22% in incidence. In 2019, the mean YLDs were 28.30 in women versus 25.48 in men; prevalence was 49.55 versus 41.08; and incidence was 919.29 versus 818.10 (all p

Conclusions

There has been a substantial rise in the burden of hip OA in the USA over the past three decades. Women and residents of the Northeastern USA are disproportionately affected. These findings underscore the need for targeted public health strategies that account for geographic and sex-based disparities in hip OA burden.

Background

Lower gastrointestinal symptoms attributed to colorectal disease are common. Early diagnosis of serious colorectal disease such as colorectal cancer (CRC), precancerous growths (polyps) and inflammation is important to ensure the best possible outcomes for a patient. The current ‘gold standard’ diagnostic test is colonoscopy. Colonoscopy is an invasive procedure. Some people struggle to cope with it and require intravenous sedation and/or analgesia. It is also resource-intensive, needing to be performed in specialist endoscopy units by a trained team. Across the UK, the demand for colonoscopy is outstripping capacity and the diagnosis of colorectal disease is being delayed. A colon capsule endoscope (CCE) is an alternative colorectal diagnostic. It is a ‘camera in a pill’ that can be swallowed and which passes through the gastrointestinal tract, obtaining visual images on the colon. There is now established experience of CCE in the UK. CCE might provide a less invasive method to diagnose colorectal disease if found to be accurate and effective and provide a means by which to increase the National Health Service (NHS) diagnostic capacity.

Aims and objectives

The aim of this study is to determine the diagnostic accuracy of CCE when compared with colonoscopy in representative and clinically meaningful cohorts of patients. An evaluation of the experiences of CCE for the patient and clinical team and an assessment of cost effectiveness will be undertaken.

Methods

We will undertake three research workstreams (WS). In WS1, we shall perform a paired (back-to-back) study. Each participant will swallow the CCE and then later on the same day they will have a colonoscopy. The study has been designed in collaboration with our Patient Advisory Group and as closely mirrors standard care as is possible. 973 participants will be recruited from three representative clinical contexts; suspected CRC, suspected inflammatory bowel disease and postpolypectomy surveillance. Up to 30 sites across the UK will be involved to maximise inclusivity. Measures of diagnostic accuracy will be reported along with CCE completion rates, number of colonoscopy procedures potentially prevented and adverse events, such as capsule retention. A nested substudy of intraobserver and interobserver agreement will be performed. WS2 will develop models of cost-effectiveness and WS3 will evaluate the patient and clinician experience, with reference to acceptability and choice.

Anticipated impact

The study findings will provide the evidence base to inform future colorectal diagnostic services.

Ethics and dissemination

The study has approval from the North East—Tyne and Wear South research ethics committee (REC reference 24/NE/0178, IRAS 331349). The findings will be disseminated to the NHS, National Institute for Health and Care Excellence, other clinical stakeholders and participants, patients and the public.

Prevalence of postpartum family planning uptake and its association with spousal discussion, joint decision-making and partner approval: a systematic review and meta-analysis

Por: Khurram · J. · Lal · A. · Rahim · A. · Tikmani · S. S. — Septiembre 24th 2025 at 03:32
Objective

This systematic review examined the prevalence of postpartum family planning (PPFP) uptake and its association with spousal discussion and husband’s support.

Design

Systematic review and meta-analysis.

Data sources

A comprehensive literature search was conducted across PubMed (NLM), Scopus (Elsevier), Web of Science (Clarivate) and Cochrane Library (Wiley).

Eligibility criteria

The review included primary observational studies published in English between January 2014 and March 2024. Eligible studies reported prevalence and association between spousal discussion, support, approval or contraceptive use by the husband in PPFP within 12 months of childbirth.

Data extraction and synthesis

Two reviewers independently screened the articles, performed data extraction and assessed the risk of bias using the Newcastle-Ottawa Scale and Appraisal Tool for Cross-Sectional Studies. Discrepancies were resolved through consensus. Random-effects meta-analysis estimated pooled prevalence, and pooled ORs of log odds were reported for the association between spousal discussion and partner approval and PPFP uptake.

Results

Six cross-sectional studies involving 2856 postpartum women were included. The pooled prevalence of PPFP uptake was 35% (95% CI 19% to 52%). Meta-analysis showed that spousal discussion was associated with PPFP uptake (log OR=1.39 (95% CI 0.65 to 2.13), however, partner’s approval was not associated with PPFP uptake (log OR=1.49, 95% CI –0.08 to 3.06). Two studies assessed partner support, with one reporting a significant association (log OR: 1.45); joint decision-making was assessed in two studies but showed no significant association with PPFP.

Conclusions

In conclusion, the overall prevalence of PPFP uptake is low. Spousal discussion plays a critical role in enhancing PPFP uptake. These findings highlight the need for policy initiatives and programmatic interventions that promote couple communication for PPFP decision-making to improve reproductive health outcomes in low–middle-income countries.

Introduction

Work engagement, defined as a positive, fulfilling, work-related state of mind characterized by vigor, dedication, and absorption, is crucial for nurse retention and quality of care in high-stress environments. Neonatal Intensive Care Units (NICUs) present unique emotional and psychological challenges for nurses, necessitating skills like emotional intelligence (EI) to enhance work engagement. This study investigates the association between EI, demographic factors, and work engagement among Palestinian NICU nurses.

Methods

A cross-sectional, descriptive correlational design was employed during February-April 2025. Of 230 nurses invited, 207 completed the survey (response rate = 90.2%) across 12 Palestinian NICUs using convenience sampling. Data analysis was conducted using descriptive statistics, Pearson’s correlation, and multiple linear regression via SPSS v26. Validated tools, the Schutte Self-Report Emotional Intelligence Test (SSEIT) and Utrecht Work Engagement Scale (UWES), were used.

Results

Emotional intelligence (EI) demonstrated a strong positive correlation with work engagement (r = 0.693, p B = 0.463, β = 0.535, p = 0.002), female gender (B = −2.250, β = −0.115, p = 0.017), and rotating shifts (B = 1.579, β = 0.105, p = 0.028) were significant predictors. EI was the strongest predictor (B = 0.358, β = 0.593, p M = 47.3 ± 5.8).

Discussion

The findings demonstrate strong associations between EI and engagement in high-stress NICU environments. Based on these findings, we propose implementing comprehensive EI training programs in nursing curricula, establishing mentorship programs to address age-related disparities, and developing gender-sensitive workplace policies to optimize work engagement and improve patient care quality.

Medication use patterns and polypharmacy among elderly in Iran: a cross-sectional study using national health insurance claims data

Por: Ataei · S. M.-N. · Golestani · A. · Khosravi · S. · Tabatabaei-Malazy · O. · Malekpour · M.-R. · Ebrahimpur · M. · Mirzadeh · F. S. · Shahali · Z. · Amini · M. R. · Effatpanah · M. — Agosto 21st 2025 at 10:00
Objectives

Polypharmacy, defined as the concurrent use of multiple medications, is a growing concern among the elderly, especially in low-income and middle-income countries such as Iran. This study aims to explore the prevalence and patterns of polypharmacy among the elderly in Iran, using health insurance claims data to identify common drug classes and coprescribed medications, with a focus on informing policy decisions and improving medication management.

Design

Retrospective population-based observational study.

Setting

Nationwide data from the Iran Health Insurance Organization (IHIO) across 24 provinces.

Participants

1 876 527 individuals aged 65 years and older, insured by the IHIO from 2014 to 2017. Individuals with incomplete demographic information or lacking medication records in the database were excluded from the analysis.

Primary and secondary outcome measures

Prevalence and patterns of polypharmacy, demographic factors associated with polypharmacy, and common drug classes used. Medications were classified using the Anatomical Therapeutic Chemical system. Polypharmacy was defined as the use of five or more medications, with cumulative polypharmacy considering total drug use over time, and consecutive polypharmacy focusing on the frequency of monthly drug use. Logistic regression and association rule mining were applied to explore demographic factors and medication patterns associated with polypharmacy.

Results

Of the study population, 74.9% experienced cumulative polypharmacy over 6 months and 64.6% over 1 month, with 7.6% experiencing consecutive polypharmacy. Females and those aged 75–79 were more prone to polypharmacy. Systemic glucocorticoids were the most commonly used medications (50.02%), followed by HMG-CoA reductase inhibitors (42.73%) and platelet aggregation inhibitors (41.92%). Polypharmacy was most strongly associated with medications related to the alimentary tract and metabolism, cardiovascular system, nervous system and blood and blood-forming organs.

Conclusions

Polypharmacy is highly prevalent among the elderly in Iran, with significant variations by gender, age, insurance fund and region. The findings highlight the need for targeted interventions to manage polypharmacy and improve medication safety in this population.

Por: Alhmoud · E. · Barazi · R. · Zakaria · A. · Andraous · L. · El Enany · R. · Thomas · B. · Abdulrouf · P. V. · Pathan · S. A. · Nazar · H. · Ibrahim · M. I. M. · Hadi · M. A. — Agosto 5th 2025 at 19:02
Introduction

Transitions from the emergency department (ED) to home are high-risk periods for medication-related harm. Pharmacist-led interventions during this period may improve medication safety and care continuity, yet co-design approaches to develop such interventions remain underused. The aim of this study is to co-design a pharmacist-led transition of care programme for patients discharged from the ED.

Methods and analysis

This study will be conducted at a 371-bed secondary-care teaching hospital in Qatar and will follow two sequential phases using qualitative and participatory methods. Phase I will involve focus groups and semistructured interviews with key stakeholders (clinical pharmacists, physicians, nurses and patients or patient representatives). Phase II will consist of an intervention co-design workshop with decision makers (leaders, policymakers and representatives from Phase I). Participants will be recruited using purposive and snowball sampling. Interviews will be audio recorded and transcribed verbatim. Data will be analysed using an inductive-deductive approach, guided by the Theoretical Domains Framework, the Care Transitions Framework and the APEASE (Affordability, Practicability, Effectiveness/cost-effectiveness, Acceptability, Side-effects/safety, Equity) criteria for evaluation of intervention feasibility.

The anticipated outcome is a prototype intervention detailing target recipients, core components, workflow, implementation strategies and supporting tools. This prototype will be pilot-tested to assess feasibility and inform further refinement.

Ethics and dissemination

The study was approved by the Medical Research Centre of Hamad Medical Corporation-Qatar (MRC-01-24-699) and Qatar University Institutional Review Board (QU-IRB 009/2025-EM). Written informed consent will be obtained from all study participants prior to participation. Research findings will be disseminated through institutional stakeholder briefings, presentations at national and international scientific conferences and publication in peer-reviewed journals. Patient representatives will contribute throughout the intervention development process.

Introduction

Admission to a surgical intensive care unit (ICU) following major surgery is associated with a number of discomforts, not only related to the disease itself but also to the care provided or the ICU environment itself (lights, sounds, pain, sleep deprivation, thirst, etc). This discomfort is real and can be associated with psychological consequences. We hypothesised that the use of immersive virtual reality (IVR) with HypnoVR is feasible and can help reduce discomfort in intensive care.

Methods and analysis

The ZION trial is a prospective, monocentric trial randomising 194 patients admitted to a surgical ICU after a major surgery. The inclusion criterion is patients admitted to a surgical ICU for at least 48 hours following major surgery (cardiac, thoracic or major abdominal surgery). Patients will be allocated to the intervention group (n=97) or the control group (n=97). In the intervention group, patients will receive IVR using HypnoVR two times a day during the ICU stay (2–5 days). In the control group, postoperative care will be conducted according to standard care without IVR. The primary endpoint will be the 18-item IPREA (Inconforts des Patients de REAnimation) questionnaire on the day of ICU discharge. The secondary endpoints will include intensity of discomfort symptoms (anxiety, pain, dyspnoea, thirst and sleep deprivation); the 18-Item IPREA Questionnaire assessed daily from randomisation to the V1 follow-up visit (ICU discharge); incidence of delirium; cumulative morphine consumption at ICU discharge; length of ICU stay and anxiety or depression at 1 month after discharge from intensive care and patient experience of device use.

Ethics and dissemination

Ethical approval was obtained from the institutional review board of the University Hospital of Amiens (Registration number ID: 2024-A01528-39) in January 2025.

Introduction

Osteoporosis is a skeletal condition with decreased bone mass and structural deterioration, increasing fracture vulnerability. Several studies have found a correlation between prostate cancer in men and an increased risk of osteoporosis. This study aims to determine the prevalence of osteoporosis in patients with prostate cancer.

Methods and analysis

The primary objective of this study will be to estimate the prevalence of osteoporosis in prostate cancer survivor patients. An extensive search will be conducted on PubMed, Scopus, Embase, Web of Science, CINAHL and ProQuest databases to ensure comprehensive coverage. The search will encompass the timeframe from 1 January 1994 to 24 September 2024. Furthermore, we will not impose any limitations on the language or geographical location of the published studies. In order to assess the potential bias in the included studies, the Joanna Briggs Institute critical appraisal checklist for prevalence studies will be employed. The analysis of data will be performed using STATA V.17. The prevalence of osteoporosis or osteopenia will be calculated for each study by dividing the number of participants with these conditions by the total number of patients diagnosed with prostate cancer. A subgroup analysis will examine prevalence regarding geographical location, age groups, ethnicity, definitions and measurements of osteoporosis or osteopenia, risk of bias in the included studies, type and duration of androgen deprivation therapy, and site of osteoporosis diagnosis. We will employ multiple methods to detect publication bias, including funnel plot analysis, Begg’s and Egger’s tests, and the Trim and Fill method. If we have enough data, we will conduct a sensitivity analysis using the leave-one-out-remove method.

Ethics and dissemination

No ethical approval or patient consent is required as this study synthesises only published aggregate data. Results will be disseminated via a peer-reviewed publication.

Integrating artificial intelligence in community-based diabetes care programmes: enhancing inclusiveness, diversity, equity and accessibility a realist review protocol

Por: Hassan · S. · Ibrahim · S. · Bielecki · J. · Stanimirovic · A. · Mathew · S. · Hooey · R. · Bowen · J. M. · Rac · V. E. — Julio 15th 2025 at 09:31
Introduction

Marginalised populations—such as racialised groups, low-income individuals, newcomers and those in rural areas—disproportionately experience severe diabetes-related complications, including diabetic foot ulcers, retinopathy and amputations, due to systemic inequities and limited access to care. Although community-based programmes address cultural and accessibility barriers, their isolation from mainstream healthcare systems leads to fragmented care and missed opportunities for early intervention.

Artificial intelligence (AI)-powered technologies can enhance accessibility and personalisation, particularly for underserved populations. However, integrating AI into community settings remains underexplored, with socioethical concerns around inclusion, diversity, equity and accessibility requiring urgent attention.

This realist review aims to examine how, why and under what circumstances AI applications can be effectively integrated into community-based diabetic care for marginalised populations. The review will develop a programme theory to guide ethical, inclusive and effective AI implementation to ensure AI-driven innovations address health disparities and promote culturally sensitive, accessible care for all.

Methods and analysis

Using the Preferred Reporting Items for Systematic Reviews and Meta Analyses (PRISMA) extension for Reviews guidelines, this realist review will systematically search MEDLINE, Embase, CINAHL, Cochrane library, Google Scholar and Scopus, alongside grey literature. A two-stage screening process will identify eligible studies, and data extraction will use a developed tool. Synthesis will employ realist logic, analysing relationships between contexts (eg, organisational capacity), mechanisms (eg, AI functionalities) and outcomes (eg, reduced disparities).

Ethics and dissemination

Ethics approval is not required for conducting this realist review. Ethics approval will be obtained from the University of Toronto; however, following the completion of the realist review for patients and community members’ engagement to support knowledge mobilisation and dissemination to ensure practical application and reciprocity.

by Weam Mohamed Meargni Ahmed, Malaz M. Abdalmotalib, Mohamed H. Elbadawi, Galia Tajelsir Fadulelmula Mohammed, Waad Mohamed Ibrahim Mohamed, Fatima Salih Babiker Mohammed, Hajar Saad Salih, Hiba Omer Yousif Mohamed

Background

Artificial intelligence (AI) is revolutionizing education globally, yet its adoption in medical education remains inadequately understood. ChatGPT, a generative AI tool, offers promising yet doubtful potential for enhancing academic and clinical training.

Methods

This study employed an analytical cross-sectional design, involving 1,443 Sudanese medical students who participated through an online, structured questionnaire. The questionnaire was designed to assess ChatGPT awareness, usage, and associated factors. Statistical analysis was performed using SPSS software to identify key determinants influencing ChatGPT awareness and usage among the participants.

Objective

This study investigates the levels of awareness, attitude, and usage of ChatGPT among Sudanese medical students, identifying key socio-demographic, economic, and institutional factors influencing its adoption.

Results

Among the participants, 65.8% were aware of ChatGPT, yet only 41.9% reported using it. Gender differences were statistically significant, with males demonstrating higher usage rates (p 300,000 SDGs) showed significantly greater usage (p  Conclusions

The findings underscore the urgent need for targeted interventions, including curriculum reform to integrate AI literacy, enhanced digital infrastructure, and gender-equity initiatives. Addressing these systemic gaps will scale up AI adoption in medical education. This study provides actionable insights for educators and policymakers, emphasizing the urgency of bridging socio-economic and institutional inequities to foster equitable access to AI tools in medical training.

Therapeutic application of nano-encapsulated pomegranate peel extract attenuated DSS-induced colitis: Antioxidant and anti-inflammatory role and reduction of exaggerated response of endoplasmic reticulum stress

by Abdallah Tageldein Mansour, Safaa I. Khater, Hemmat M. Eissa, Helal F. Al-Harthi, Areej A. Eskandrani, Mohammed Ageeli Hakami, Wafa S. Alansari, Amirah Albaqami, Hanan M. Alharbi, Tarek Khamis, Doaa Ibrahim

The medicinal application of pomegranate peel extract enriched with polyphenols (PPE) as a therapeutic strategy for managing inflammatory bowel diseases (IBD) is still limited. Integrating pomegranate peel extract (PPE) into an effective nanocarrier system could enhance its mechanistic actions, potentially aiding in the remission of colitis. Therefore, this approach aimed to enhance PPE’s stability and bioavailability and investigate mitigating impact of pomegranate peel extract-loaded nanoparticles (PPE-NPs) in a colitis model. Colonic injury was induced by 5% dextran sulfate sodium (DSS) and efficacy of disease progression after oral administration of PPE-NPs for 14 days was assessed by evaluating clinical signs severity, antioxidant and inflammatory markers, expressions of endoplasmic reticulum associated genes and histopathological and immunostaining analysis in colonic tissues. Clinical signs and disease activity index were effectively reduced, and the levels of fecal calprotectin were decreased in groups treated with PPE-NPs compared to DSS group. The colitic group showed a significant increase (P IL-17, TNF-α, and IL-1β (increased up to 2.99, 4.36 and 4.90 respectively unlike PPE-NPsIII that recorded reduced levels of CRP, MPO and NO (8,96, 78.30 and 123 nmol/g tissue respectively) and much lower (P CHOP, JUNK, ATF6, BIP, and Elf-2) and immunostaining expression regulation of key markers regulating autophagy (Beclin-2) in this group. The histopathological changes in the colon were less severe in the PPE-NPs received groups (especially at the level of 150 mg/kg) compared to DSS group. Collectively, these findings suggest that the nanoencapsulation of PPE enhances its effectiveness in promoting recovery of colonic tissue damage and achieving remission of colitis.

Background

Among acute stroke patients (ASPs), diabetes mellitus (DM) is associated with a higher risk of death, functional dependency, and recurrence. This study aimed to determine the impact of DM on the 30-day mortality among admitted ASPs in northern Tanzania.

Materials and methods

This was a hospital-based prospective cohort study performed among ASPs with and without DM who were admitted to Kilimanjaro Christian Medical Centre from November 2022 to May2023. ASPs were followed for 30 days after the onset of an acute stroke to identify the primary outcome, which was all-cause mortality. Descriptive statistics, logistic regression, and survival analysis were conducted,

Results

Out of 213 ASP, 82 (38.5%) had DM. The overall crude mortality rate was 46.9%. ASPs with DM had a higher mortality rate of 53.7% compared with those without DM (42.7%). A higher proportion of acute stroke patients with DM (84.1%) had a poor outcome (mRS 3-6) (p = 0.038). DM was statistically non-significant for 30-day mortality (aHR 1.56; 95% CI: 0.73–3.32; p = 0.252). However, fever (p = 0.005), severe admission Glasgow coma scale (p = 0.005), severe stroke (p = 0.008), elevated serum creatinine (p = 0.008), and an abnormal respiratory pattern (p = 0.042), were predictors of 30-day mortality,

Conclusion

This study demonstrated a high mortality in ASPs. Although DM did not have a significant impact on 30-day mortality, other factors, such as altered mental state, stroke severity, fever, elevated creatinine, and abnormal respiration, need to be accounted for that may have a significant impact on the mortality in ASPs. These findings highlight the significant burden of DM in stroke patients and underscore the importance of early diagnosis and treatment of ASPs, in the hopes of improving clinical practice and guidelines and reducing morbidity and mortality in Tanzania.

The formation of macrophage (Mφ) foam cells is a hallmark of atherosclerosis, yet how the process of lipid loading can modulate Mφ inflammatory responses by rewiring their intracellular metabolic circuits is not well understood. Our previous studies have shown that the accumulation of oxidized LDL (oxLDL) or free cholesterol in Mφs impaired their inflammatory response by suppressing HIF-1α-mediated glycolysis and upregulating NRF2 antioxidative response. However, it remains unclear if other metabolic processes are also contributory. In this study, we found that the accumulation of free cholesterol, but not oxLDL, in primary murine thioglycolate-elicited peritoneal Mφs (PMφs) enhanced a PARP1-dependent response associated with repair of DNA damage, which was characterized by poly ADP-ribosylation of proteins, phosphorylation of histone 2A.X and consumption of NAD + . Both oxLDL and cholesterol enhanced the PARP1 response after LPS stimulation. Treatment of PMφs with mitoTEMPO, a specific mitochondrial reactive oxygen species (mtROS) scavenger, alleviated mtROS during cholesterol loading, blocked the PARP1 response and partially restored LPS- induced inflammatory gene expression. In contrast to inhibition of PARP1 enzymatic activity, knockdown of PARP1 expression in RAW264.7 Mφs with siRNA elevated LPS-induced inflammatory gene expression. Overall, our study suggests that cholesterol accumulation triggers a PARP1 response to DNA damage in Mφs and that PARP1 inhibits LPS-mediated inflammation through a non-enzymatic function.

Introduction

Diabetic Retinopathy (DR) is a microvascular complication of chronic Diabetes that can lead to visual impairment if left untreated. While concerted efforts have been made to develop screening modalities to facilitate the early detection of Diabetic Retinopathy in sub-Saharan Africa, little is known about the factors impacting the optimal use of these screening services. This paper aims to identify and highlight factors associated with the access of Diabetic Retinopathy screening services from patient and service provider perspectives.

Methodology

This scoping review was conducted using the Arksey and O’Malley (2005) framework. A comprehensive search of peer-reviewed articles and grey literature was conducted from May 2023 to June 2023. Electronic databases searched include Medline, Embase, PubMed, CINAHL Complete, APA PsycINFO, Web of Science, and African Journal Online (AJOL). Two reviewers independently screened the retrieved records for eligibility, and relevant data was extracted from the included studies. A descriptive overview of key findings was provided, and the 5As conceptual framework of access to healthcare was used to map the identified factors.

Results

The search strategy yielded 873 records. Of those, 19 studies met the criteria for inclusion. Health literacy and duration of Diabetes were reported in 12 and 9 studies as the most common factors associated with DR screening services access. Similarly, age at onset and inadequate referral by healthcare providers were cited as significant determinants of DR screening access in 7 studies, respectively.

Conclusion

The 5As framework of access to healthcare aids our understanding of factors associated with the access of DR screening from patient and service provider standpoints. To address these issues, there is a need for more research on this topic to design effective DR screening services in the region.

Mycobacterium tuberculosis is a lethal human pathogen, with the key flavoenzyme for catalyzing bacterial cell-wall biosynthesis, decaprenylphosphoryl-D-ribose oxidase (DprE1), considered an Achilles heal for tuberculosis (TB) progression. Inhibition of DprE1 blocks cell wall biosynthesis and is a highly promising antitubercular target. Macozinone (PBTZ169, a benzothiazinone (BTZ) derivative) is an irreversible DprE1 inhibitor that has attracted considerable attention because it exhibits an additive activity when combined with other anti-TB drugs. Herein, 754 BTZ analogs were assembled in a virtual library and evaluated against the DprE1 target using a covalent docking approach. After validation of the employed covalent docking approach, BTZ analogs were screened. Analogs with a docking score less than –9.0 kcal/mol were advanced for molecular dynamics (MD) simulations, followed by binding energy evaluations utilizing the MM-GBSA approach. Three BTZ analogs–namely, PubChem-155-924-621, PubChem-127-032-794, and PubChem-155-923-972– exhibited higher binding affinities against DprE1 compared to PBTZ169 with ΔGbinding values of –77.2, –74.3, and –65.4 kcal/mol, versus –49.8 kcal/mol, respectively. Structural and energetical analyses were performed for the identified analogs against DprE1 throughout the 100 ns MD simulations, and the results demonstrated the great stability of the identified BTZ analogs. Physicochemical and ADMET characteristics indicated the oral bioavailability of the identified BTZ analogs. The obtained in-silico results provide promising anti-TB inhibitors that are worth being subjected to in-vitro and in-vivo investigations.

Cervical cancer ranked fourth most common malignancy among women worldwide despite the establishment of vaccination programmes. This systematic review evaluates the anti-cancer properties of turmeric and ginger bioactive compounds, specifically curcumin, 6/10-gingerol, and 6/10-shogaol, and their combination in cervical cancer through in-vitro and in-vivo models. A comprehensive electronic search was performed using Science Direct, PubMed, and Scopus from inception until the second week of June 2024 for studies published in English. Only studies investigating the effects of curcumin, gingerol, shogaol, and/or their combination in human cervical cancer cell lines and/or rodent animal models implanted with cervical cancer xenografts were included. Altogether, 27 studies were included in this review. The evidence gathered indicated that curcumin, 6/10-gingerol and 6-shogaol exert their anticancer action through modulation of cell signalling pathways, including AMPK, WNT, PI3K/AKT, and NF‐κB pathway, and mediators including Bax/Bcl2, TNF‐α, EGFR, COX‐2, caspases‐3, ‐9, p53, and pRb. However, the synergistic effect of these bioactive compounds is not known due to lack of evidence. In conclusion, curcumin, 6/10-gingerols, and 6-shogaols hold promise as therapeutic agents for cervical cancer. Yet, further research is essential to understand their combined efficacy, emphasising the need for additional studies exploring the synergistic anticancer effects of these bioactive compounds. Additional factors to explore include long-term effects and susceptibility of chemoresistant cervical cancer cells towards curcumin, shogaols, and gingerols.
