To assess the association between the maternal continuum of healthcare and child immunisation in East Africa using propensity score matching (PSM).
Cross-sectional study using Demographic and Health Survey data.
This study was conducted in East African countries.
This study included a weighted sample of 13 488 women with children aged 12–23 months.
Child immunisation was the outcome variable of this study.
The PSM estimates indicate that the average treatment effect on the treated for complete child immunisation was 0.0583, meaning that children of mothers who received a complete maternal continuum of care had a 5.83% higher probability of being fully immunised compared with children of mothers with incomplete care. Expressed relative to the treated group’s mean, this corresponds to a 7.48% increase. Additionally, our results indicated that the population average treatment effect was 0.0629. This means that, on average, a complete continuum of maternal healthcare increases the probability of full child immunisation by approximately 6.29% across the entire population.
The study highlights that children whose mothers receive comprehensive maternal healthcare are more likely to complete their childhood immunisations. This finding underscores the need to integrate immunisation services into maternal healthcare programmes to enhance vaccination coverage and promote better child health. To maximise this connection, improving access to maternal healthcare, especially in underserved regions, is crucial, along with ensuring that immunisation is a regular part of maternal care.

Drug use is a highly stigmatized behavior, and drug-related stigma is a key driver of behavioral risk, lower health care utilization, and associated adverse health outcomes among people who inject drugs (PWID). While instruments exist for measuring drug-related stigma, their applicability to community-based PWID across multiple stigma types (enacted, anticipated, internalized) and settings (health care, society, family) is limited, as most were developed using treatment-based samples and all were developed in urban populations. This study sought to develop a Drug Use Stigma Scale (DUSS) that addresses these limitations. We developed an initial list of 39 items based on literature review and qualitative interviews (N = 27) and three focus groups (N = 28) with PWID recruited from syringe services programs and via peer referral in two predominantly rural West Virginia counties. The scale items were administered in a survey to 336 PWID recruited from the same two counties divided into development and validation samples. Responses to the 39-item scale went through a multidimensional refinement process, including examination of internal consistency, Confirmatory Factor Analysis (CFA), and a three-factor CFA based on stigma setting. Next, a set of final measurement CFAs were conducted. Finally, the resulting scale was examined for criterion-related concurrent validation. The final DUSS consisted of 16 items with excellent fit statistics for the development sample: SRMR: 0.03, RMSEA: 0.09, GFI: 0.92, CFI: 0.96, NFI: 0.94. Fit attenuated but remained satisfactory for the validation sample. DUSS scores were significantly associated with increased odds of not seeking healthcare when needed (OR: 1.47, p = 0.001; OR: 1.61, pby Berihun Agegn Mengistie, Getie Mihret Aragaw, Tazeb Alemu Anteneh, Kindu Yinges Wondie, Alemneh Tadesse Kassie, Alemken Eyayu Abuhay, Wondimnew Mersha Biset, Gebrye Gizaw Mulatu, Nuhamin Tesfa Tsega
BackgroundPrecancerous cervical lesions, or cervical intraepithelial neoplasia (CIN), represent a significant precursor to cervical cancer, posing a considerable threat to women’s health globally, particularly in developing countries. In Africa, the burden of premalignant cervical lesions is not well studied. Therefore, the main purpose of this systematic review and meta-analysis was to determine the overall prevalence of precancerous cervical lesions and identifying determinants among women who underwent cervical cancer screening in Africa.
MethodsThis study followed the Preferred Reporting Item Review and Meta-analysis (PRISMA) guidelines. The protocol for this systematic review and meta-analysis was registered on the International Prospective Register of Systematic Reviews (PROSPERO) (ID: CRD42025645427). We carried out a systematic and comprehensive search on electronic databases such as PubMed and Hinari. In addition, Google Scholar and ScienceDirect were utilized to find relevant studies related to precancerous cervical lesions. Data from the included studies were extracted using an Excel spreadsheet and analyzed using STATA version 17. The methodological quality of the eligible studies was examined using the Joanna Briggs Institute (JBI) assessment tool. Publication bias was checked by using the funnel plot and Egger’s tests. A random-effects model using the Der Simonian Laird method was used to estimate the pooled prevalence of pre-cancerous cervical lesions in Africa. The I-squared and Cochrane Q statistics were used to assess the level of statistical heterogeneity among the included studies.
ResultsA total of 112 eligible articles conducted in Africa, encompassing 212,984 study participants, were included in the quantitative meta-analysis. Thus, the pooled prevalence of pre-cancerous cervical lesions in Africa was 17.06% (95% confidence interval: 15.47%−18.68%). In this review, having no formal education (AOR = 4.07, 95% CI: 1.74, 9.53), being rural dweller(AOR = 2.38, 95% CI: 1.64, 3.46), history of STIs (AOR = 3.94, 95% CI: 2.97, 5.23), history of having multiple partners (AOR = 2.73, 95% CI: 2.28, 3.28), early initiation of coitus (AOR = 2.77, 95% CI: 2.11, 3.62), being HIV-seropositive women (AOR = 3.33, 95% CI: 2.32, 4.78), a CD4 count Conclusions
In Africa, the overall prevalence of pre-cancerous cervical lesions is high (17%). The findings of this review highlight that health professionals, health administrators, and all other concerned bodies need to work in collaboration to expand comprehensive cervical cancer screening methods in healthcare facilities for early detection and treatment of cervical lesions. In addition, increasing community awareness and health education, expanding visual inspection of the cervix with acetic acid in rural areas, offering special attention to high-risk groups (HIV-positive women), encouraging adherence to antiretroviral therapy for HIV-positive women, overcoming risky sexual behaviors and practices, and advocating early detection and treatment of precancerous cervical lesions.
Psychosocial stress is a major public health concern, contributing to significant suffering and costs to society. There is a lack of effective interventions that could be offered at an early stage to people who need to reduce their stress in life. Recent advances in psychology have provided evidence-based exercises suitable for testing in an entirely digital intervention. This study aims to estimate the effectiveness of a 12-week digital course in mindfulness- and acceptance-based stress reduction.
The effectiveness of the 12-week digital course will be estimated in a parallel-groups randomised controlled trial, in which the control group will receive referrals to self-studies on mental health information found online. The study population will be individuals 15 or older, seeking help online for stress and who have access to a mobile phone. Employing a Bayesian sequential design, the primary outcome will be monitored monthly, after the 6-month follow-up, to calculate target criteria for when to stop recruiting. Perceived stress (Cohen’s 10-item version) will be the primary outcome, with estimands of interest being differences between groups at 3 (immediate), 6 (prolonged) and 12 months (maintained). Mediation analysis will reveal if differences between groups are mediated by acquired equanimity. Effectiveness will be analysed with Bayesian regression models, and mediation will be analysed by using a causal inference framework.
The research was approved by the Swedish Ethical Review Authority on 2024-05-07 (2024-01974-01). The study will reach out to a vulnerable population, and participation may displace efforts to seek professional help. We have built-in automatic advice to seek additional help for participants scoring high on the depression scale at baseline, before allocation to study groups. The findings from this study will be submitted to peer-reviewed journals and presented at relevant national and international meetings.

IntroductionOccupational pesticide exposure poses significant health risks, particularly among smallholder farmers in developing countries like Ghana, where such exposures are common due to widespread subsistence agricultural activities. The Environmental Protection Agency (EPA) of Ghana is responsible for registering and monitoring pesticide use and regulating the presence of unregistered or banned products on the local market; however, this regulation is ineffective. Farmers frequently acquire pesticides directly from vendors who may not possess sufficient training, and the lack of stringent measures facilitates the accessibility of hazardous products. Furthermore, while regulations mandate safe handling and disposal practices, there are also possible oversights at the community level, leaving farmers largely dependent on their own knowledge, practices, or what they have learnt from other colleagues. This study explores the safety practices, perceived exposure levels, and awareness among rural farmers in the Hohoe municipality of Ghana.
MethodsA qualitative ethnographic approach was adopted, involving in-depth interviews with 13 purposively selected farmers with over five years of farming experience. Data was collected using semi-structured interviews guide informed by prior literature. Thematic analysis was conducted using ATLAS.ti version 25, with open and selective coding techniques.
ResultsFour major themes emerged: knowledge and practices of pesticide use, health risks and exposure, safety practices, pesticide storage and disposal. Most farmers (approximately 10 out of 13) reported using Glyphosate as their primary herbicide, followed by Paraquat Dichloride and 2,4-D, relying on vendor recommendations for application methods. Common health complaints included eye and skin irritation, waist pain, and temporary vision loss. While some farmers used PPE like boots and gloves, many lacked complete protective gear, especially eye protection. Pesticide containers were often stored at home or discarded on farms or by burning, indicating poor disposal practices. Awareness of pesticide expiry dates and proper dosage was inconsistent.
ConclusionThe study reveals substantial gaps in pesticide safety knowledge and practices among rural farmers, posing significant public health risks. Targeted interventions, including regular training on safe pesticide handling, PPE use, and environmentally sound disposal methods, are critical to reducing occupational exposure and its associated health burdens.

BackgroundAlthough the SBAR framework is widely used in clinical and educational settings, there is a lack of validated Spanish-language tools that objectively assess its use by students in simulation. The adaptation and validation of the SBAR-LA rubric address this gap and provide a resource for training and evaluating structured communication.
ObjectiveTo conduct the cross-cultural adaptation and psychometric validation of the SBAR-LA rubric in Spanish for assessing structured communication skills in undergraduate nursing students during clinical simulation.
MethodsA two-phase cross-sectional psychometric validation study was conducted. Phase one involved cross-cultural adaptation, including forward and backward translation, expert panel review, and cognitive debriefing with nursing students. Phase two assessed inter-rater reliability using Krippendorff’s alpha based on 97 performance evaluations obtained in different simulation scenarios. The SBAR-LA-Sp rubric contains 10 dichotomous items across the four SBAR dimensions.
ResultsThe Spanish version of the SBAR-LA rubric demonstrated excellent inter-rater reliability, with a Krippendorff’s alpha of 0.933 (95% CI: 0.905–0.956). Internal consistency and agreement between raters were also high, confirming the instrument’s robustness.
ConclusionsThe Spanish version of the SBAR-LA rubric provides an objective measure of structured communication in nursing simulation. The findings support its use in academic training. Further research is needed to examine its effect on learning outcomes.

IntroductionExtended spectrum β-lactamase (ESBL) and carbapenemase-producing Escherichia coli (E. coli) and Klebsiella pneumoniae (K. pneumoniae) emanating from raw cow milk are among the leading contributors to the spread of antimicrobial resistance (AMR). Due to the misuse and overuse of antibiotics in dairy farms, cow’s milk has become a reservoir of ESBL- and carbapenemase-producing E. coli and K. pneumoniae posing a growing public health threat, especially in areas where the consumption of raw milk is common. However, compared to the clinical sector, the prevalence of ESBL- and carbapenemase-producing E. coli and K. pneumoniae in the food sector is under-studied.
ObjectiveThis study aimed to determine the prevalence of ESBL and carbapenemase-producing E. coli and K. pneumoniae in raw bulk cow milk from Dairy Cooperatives in Northwest Amhara, Ethiopia.
MethodsA cross-sectional study was conducted from January to April, 2025 among 257 dairy cooperative member farms. Sociodemographic and related data were collected using a structured questionnaire. Five milliliters of raw bulk cow milk were collected aseptically from each farm in four Dairy Cooperatives (DCs) (DC-A to D). 10 microliters of milk sample were directly inoculated into MacConkey agar. Escherichia coli and K. pneumoniae were identified using standard microbiological techniques. Antimicrobial susceptibility testing was performed using the Kirby-Bauer disk diffusion method. ESBL and carbapenemase production were confirmed phenotypically via combination disk tests and modified carbapenem inactivation methods, respectively.
ResultsThe prevalence of E. coli and/or K. pneumoniae in raw cow milk was 21% (95% CI, 16.5–26.4%), with respective individual prevalence of 8.2% and 14.8%. ESBL-producing E. coli and K. pneumoniae accounted for 23.8% and 15.8% of isolates, respectively, while 2.6% of isolates (only K. pneumoniae) were carbapenemase producers. Resistance to ampicillin and amoxicillin-clavulanic acid exceeded 70%. All E. coli and 94.7% of K. pneumoniae isolates remained susceptible to carbapenems. Nearly half of all isolates (45.8%) were multidrug resistant (MDR), and 51.9% of MDR isolates were co-resistant to at least six antibiotics. Having additional non-farming occupations (AOR: 4.17, 95% CI: 1.49–11.67), large herd size (AOR: 3.21, 95% CI: 1.26–8.18), having pet animals (AOR: 6.53, 95% CI: 1.39–30.7), and use of calabash milk pail (AOR: 7.37, 95% CI: 1.45–37.49) were significantly associated with milk culture positive result for E. coli and/or K. pneumoniae.
ConclusionRaw milk in Northwest Amhara harbors ESBL and carbapenemase-producing E. coli and K. pneumoniae posing a substantial public health risk coupled with MDR and resistance to critically important antimicrobials. Strengthened AMR surveillance, improved farm hygiene, restricted antibiotic use, and public education on milk safety are urgently needed.
To examine the effects of 12 weeks group-based peer-led aquatic high-intensity interval training (AHIIT) compared with aquatic moderate continuous training (AMICT) on patient-reported outcome measures (PROMs) and quality-adjusted life-years (QALYs).
A single-blind, parallel-group, randomised trial with a 1:1 allocation ratio.
Community-based setting.
89 participants (mean age 62 (SD 13) years) with rheumatic and musculoskeletal diseases, including hip and knee osteoarthritis, fibromyalgia, rheumatoid arthritis, psoriatic arthritis and axial spondyloarthritis, were randomly allocated to an AHIIT (n=44) or an AMICT (n=45) group.
The intervention consisted of AHIIT (four intervals of 4 min at high intensity, Borg scale 14–18) or AMICT (Borg scale 12–13), conducted twice weekly for 12 weeks.
Outcomes included disease activity (measured by the Patient Global Assessment), fatigue, pain and health-related quality of life (HRQoL), measured by the EQ-5D utility index (five-dimensional health status measure) and EQ VAS (self-rated overall health scale) for overall health, physical and social activities. All outcomes were assessed at baseline, 3 months and 6 months. To compare the overall benefit of these interventions, QALYs were estimated based on HRQoL. Linear mixed models for repeated measures were used to estimate the mean difference (95% CI) in outcomes.
No statistically significant differences between the groups were found in any outcomes at either three or 6 months (p>0.05).
No difference between the groups was found on PROMs and QALYs. Future research should include larger sample sizes and a non-exercising control group to better determine the efficacy of AHIIT and clarify the role of exercise intensity in symptom management.
Glioblastoma multiforme (GBM) is an aggressive primary brain tumour associated with a poor prognosis despite standard-of-care treatment, including surgical resection, radiotherapy and temozolomide (TMZ) chemotherapy. Certepetide (also known as LSTA1, CEND-1) is an investigational tumour-penetrating peptide that facilitates the extravascular delivery and intratumoural penetration of co-administered immune/chemotherapeutics; however, it has not yet been evaluated in clinical trials for the treatment of intracranial malignancies.
LSTA1-GBM-2A is an exploratory phase 2a, double-blind, placebo-controlled, randomised, proof-of-concept investigator-initiated trial assessing the safety, tolerability and preliminary efficacy of certepetide in combination with standard-of-care TMZ, compared with TMZ with a matching placebo, in subjects with newly diagnosed GBM.
The trial is funded by Lisata Therapeutics, sponsored by Tartu University Hospital and conducted at hospitals in Estonia and Latvia. Subjects are randomised in a 2:1 ratio. Following initial surgery and radiotherapy with concurrent TMZ, the subjects receive intravenous certepetide or placebo alongside six cycles of adjuvant TMZ treatment. The primary endpoint is overall survival. The target number of subjects is 30. The first subject was recruited in January 2024, and accrual is ongoing.
This study was approved by the Republic of Estonia State Agency of Medicines (17 October 2023) and the State Agency of Medicines of the Republic of Latvia (1 February 2024). The results of this study will be published in peer-reviewed journals and reported at academic conferences.

To identify the prevalence and types of missed nursing care in a Danish hospital context from patients' perspectives and to examine associations between missed nursing care, patient demographics, and patient-reported adverse events.
Cross-sectional study.
A total of 284 medical and surgical patients from 21 wards at a Danish university hospital completed the Danish version of the MISSCARE Survey–Patient. Descriptive statistics and analyses of associations between missed nursing care and patient demographics and adverse events were conducted.
Patients reported an overall prevalence of missed nursing care of 15%, with most omissions occurring in the physical care domain (22%), followed by psychosocial care (13%) and timeliness (6%). The most frequently missed activities included oral care, clarity about which nurse was responsible for their care, repositioning in bed, and help with eating. Medication errors were significantly associated with higher missed nursing care scores across all domains, while associations with other adverse events and demographics were inconsistent.
Patients generally perceived a low prevalence of missed nursing care, although notable variations were observed across care domains and specific activities. Incorporating patient perspectives alongside nurse perspectives offers a more complete understanding of missed nursing care.
Continuous assessment of missed nursing care from patients' perspectives could serve as a valuable complement to nurse-reported assessments, helping to identify specific areas for improvement. Targeted interventions addressing activities with higher patient-reported missed nursing care may enhance both care quality and patient outcomes.
STROBE guidelines were followed.
Patients were not involved in the study's design, conduct, or reporting.
This study highlights missed nursing care from patients' perspectives, revealing key care gaps. The findings can inform hospital administrators, nursing leaders, nursing educators, and policymakers in developing strategies to improve care quality and patient satisfaction.
Psychiatrists’ first exposure to patient suicide often occurs during residency training. Previous research shows that experiencing a patient’s death by suicide during residency can have significant impacts on trainees’ well-being, self-esteem and approach to practice. However, existing research on this topic is mostly limited to survey-based data, which does not facilitate nuanced exploration. This study will use a qualitative approach to gain an in-depth understanding of Canadian psychiatry residents’ experiences of a patient’s death by suicide and the types of supports that may help trainees to process this loss and integrate this experience into their professional identity formation.
This study will conduct 15–25 semistructured qualitative interviews with psychiatry resident physicians across Canada to explore their experiences of patient loss by suicide during training. Interview data will be transcribed verbatim and analysed using the principles of Constructivist Grounded Theory.
The study findings will be reported and accessible to residency training programmes, the academic community, the media and the public.
This study was approved by the Research Ethics Board of the Centre for Addiction and Mental Health (Protocol Identifying Number 2024/125).

Any strategy that can selectively and persistently lower the brain levels of the cellular prion protein (PrPC) is expected to extend survival in prion diseases. Recent advances in the virus-mediated delivery of gene therapies prompted us to explore if a recombinant adeno-associated virus (rAAV) vector delivering a CRISPR-Cas-based gene editor can be devised that induces a functional knockout of the prion gene. Whereas the eventual objective is to assess the therapeutic potency of an optimized vector in prion-infected mice, in this proof-of-concept study, we evaluated tools and methods that are suited to achieve this goal. The result of these efforts is a first-generation all-in-one rAAV vector that codes for a prion gene-specific guide RNA and a small Cas9 endonuclease, whose expression is controlled by a truncated neural cell adhesion molecule 1 (NCAM1) promoter that is active in PrPC expressing cells. We also constructed a second rAAV vector coding for a prion gene-specific ‘traffic light reporter’ (TLR). The TLR can be used to monitor prion gene-editing efficacy by coding for red and green fluorescent proteins separated by a segment of the prion gene that is targeted by the gene editor. For the purification of AAVs, we adopted a robust and scalable rAAV vector assembly pipeline and undertook proof-of-concept prion gene editing experiments in human cells and mice, which to date yielded prion gene editing rates of approximately 20% and 5%, respectively. Finally, we compared brain distributions of rAAV vectors following intrathalamic versus retro-orbital injection, and selected the 9P31 capsid for future studies based on a 7.5-fold higher heterologous gene expression level as compared to the PHP.eB capsid.by Inés Armenteros-Yeguas, Reynaldo Homen, Adrián Valls, Laura Dans, Eva Orviz, Oskar Ayerdi, Teresa Puerta, Mar Vera, Jorge Alfredo Pérez-García, Montserrat Torres, Mayte Coiras, Jorge Del Romero, Vicente Estrada
BackgroundMpox is a viral disease caused by an orthopoxvirus called monkeypox virus. It experienced a significant increase in cases in 2022 worldwide, mostly with sexual transmission. The possibility of hidden circulation of this infection among asymptomatic individuals remains unclear.
MethodsThis is a multi-centre, observational cross-sectional study conducted in a sexually transmitted infections (STIs) clinic in its referral hospital between July and October 2023 in Madrid, Spain. Pharyngeal and rectal swab samples were collected from each participant and processed to detect bacterial STIs and mpox. Socio-demographic, clinical and behavioural data were collected, and a descriptive analysis was performed.
ResultsA total of 343 asymptomatic participants were included. The prevalence of asymptomatic mpox infection was 0.3% (n = 1) and the only positive case developed symptoms shortly after sampling, ruling out a fully asymptomatic infection. The percentage of vaccinated individuals was 36.1%. 13.2% had previously contracted mpox. Other STIs were detected in 21.6% of participants.
ConclusionsAlthough routine screening for asymptomatic bacterial sexually transmitted infections is strongly recommended in at-risk individuals, testing for asymptomatic mpox should be evaluated based on the specific context and population. Additionally, the ongoing cases of mpox in Spain are likely not related to the presence of asymptomatic carriers.
The number of people living with dementia is increasing worldwide. Alzheimer’s disease (AD) is the most common type of dementia. It typically manifests itself initially with cognitive impairment in the memory domain and gradually progresses towards affecting all activities of daily living. Active music interventions, particularly singing, may improve mood, social behaviour and quality of life. However, little is known about their effects on cognition, although some studies have provided promising results. The Memory for Music (M4M) project aims to fill this gap in research by measuring the effects of learning new songs on cognitive functioning. Specifically, M4M will examine memory for new songs in non-musician adults with AD after undergoing intensive versus minimal individual musical training based on singing novel songs.
Home-dwelling adults with AD, 65 years or older, will receive 5 months of intensive intervention (2x/week) and 5 months of minimal intervention (1x/month). In a crossover design, participants will be randomised to receive either the intensive or minimal intervention first, with 2 months between the intervention periods. Participants will receive individual music lessons to learn new songs, provided by a music instructor with adequate training. The main outcomes will be measured at the beginning and end of each intervention period. General cognition will be measured with the AD Assessment Scale – Cognitive by an assessor blinded to the randomisation. Participants’ memory for music will be measured using the N400 component of electroencephalographic (EEG) event-related potentials in response to music stimuli. Additional outcomes evaluated during intervention sessions include mood and musical performance observations. With 113 participants randomised, the trial will have 80% power to detect clinically meaningful effects. Relations between mood, memory for music and cognitive abilities will be examined, with sex, age, AD stage, previous musical training and education as covariates. M4M will be conducted in close collaboration between academic researchers, service providers and service users to ensure relevance and applicability.
Dissemination of findings will apply to local, national and international levels. The study has been approved by the Regional Committees for Medical and Health Research Ethics in Norway (reference number 759936) and by Mautalén Salud e Investigación, CECOM in Argentina (register code 14412).
Clinicaltrials.gov, NCT06611878.
Mycoplasma genitalium, Chlamydia trachomatis, Neisseria gonorrhoeae and Trichomonas vaginalis are sexually transmitted pathogens that are highly prevalent in developing countries and are strongly associated with pregnancy complications. In Chad, screening for these sexually transmitted infections (STIs) in pregnant women is based solely on patient-reported symptoms, even though these infections are frequently asymptomatic. This study aims to determine the prevalence of M. genitalium, C. trachomatis, N. gonorrhoeae and T. vaginalis infections, as well as their associated risk factors.
In this cross-sectional study, we recruited pregnant women attending antenatal clinics at seven hospitals in N’Djamena. Endocervical swabs were collected, and DNA was extracted. Infections were diagnosed using PCR. Risk factors were identified using a structured questionnaire, and associations were assessed using logistic regression.
A total of 525 pregnant women were enrolled, of whom 78.5% resided in urban areas, with a mean age of 25.16±5.54 years. Overall, 23.99% of the study population were diagnosed with at least one STI. The individual prevalence of M. genitalium, N. gonorrhoeae, C. trachomatis and T. vaginalis infections was 13.33%, 5.14%, 0.95% and 4.57%, respectively. Coinfections were low, with M. genitalium-T. vaginalis at 0.95%, M. genitalium-N. gonorrhoeae at 0.38% and other combinations at 0.19% each. Women residing in rural areas had nearly two times the odds of M. genitalium infection compared with urban residents (OR=1.98), indicating a higher risk. AgeM. genitalium infection (OR=1.71) were also associated with significantly increased risk.
This study demonstrates a high prevalence of STIs among pregnant women in Chad, underscoring the need for systematic screening rather than solely relying on syndromic management.
To develop and validate a risk prediction model for preterm premature rupture of membranes (PPROM) to enable early identification of at-risk women and support clinical decision-making in North Wollo Zone, Ethiopia.
A hospital-based retrospective cross-sectional study.
Six public hospitals in the North Wollo Zone, Northern Ethiopia.
A total of 1098 pregnant women were included in the study using systematic random sampling.
Occurrence of PPROM.
Data were collected between 20 November 2023 and 20 March 2024, using structured interviews and medical record reviews. A risk prediction model was developed using Least Absolute Shrinkage and Selection Operator and logistic regression. Model performance was assessed through area under the curve (AUC), calibration plots and the Hosmer-Lemeshow test. Internal validation was conducted via bootstrap resampling. A simplified risk score was created to categorise women into high-risk and low-risk groups, and its clinical utility was evaluated using decision curve analysis.
Among the 1098 participants (100% response rate), the mean age was 21.54 years (IQR: 18–26), with 57.2% aged 20–34 years. The prevalence of PPROM was 10.75% (95% CI 9.01% to 12.77%). Seven significant predictors were identified: maternal age
PPROM remains a significant obstetric complication in the study area. The validated risk prediction model showed moderate to good performance and can be used to support early screening and risk-based management in antenatal care (ANC). Integrating the tool into routine ANC services, along with health education and management of modifiable risk factors, may help reduce PPROM-related adverse outcomes. Further external validation is recommended.

BackgroundMonasteries in India house individuals from childhood to advanced age. These congregate settings amplify tuberculosis (TB) transmission and exposure when the disease is present, especially in the high burden areas like Sikkim, India. However, the prevalence of active-TB disease (ATB), tuberculosis infection (TBI), and their associated risk factors have not been studied. The diagnosis and treatment of TBI remain a major bottleneck in eradicating TB. ATB and TBI risk among residents living in the congregate setting of monasteries in Sikkim, India, a high-TB burden area, may be high due to high-density living quarters, public interaction and their frequent travel history but has never been illustrated.
MethodA cross-sectional screening of the monks and residents of Rumtek Monastery (Sikkim, India) was carried out to assess extent of ATB and TBI in a congregate setting. TrueNat MTB and GeneXpert MTB/Rif systems were utilized for ATB diagnosis, whereas QuantiFERON-TB Gold Plus (QFT-plus) Interferon-gamma release assay (IGRA) analysis was used for TBI detection. Follow-up sputum testing by TrueNat MTB was performed on IGRA-positive individuals to exclude ATB.
ResultsAmong the 350 inhabitants of the monastery, 7% (25/350) were found to be symptomatic for TB, whereas 93% (325/350) were asymptomatic. Out of them, 189 participants, including symptomatic cases, agreed to participate in the study and were screened for TBI; however, 15 participants were excluded from the study due to result discrepancies. None of the participant were diagnosed with active tuberculosis (ATB), although, 44.2% (77/174) were found to be positive for TBI; however, none of those with TBI progressed to ATB during one year follow-up. Risk factors for TBI included: advancing age, frequent travel history, family history of TB or having contacts with TB patients and abnormal Body Mass Index (BMI) ≤18.5- ≥ 25.
ConclusionThis study confirms the high prevalence of TBI among residents in the congregate setting of monasteries, and justify TB prevention strategies by targeted screening, TBI testing and preventive treatment in congregate settings of high TB burden areas.

BackgroundIn sub-Saharan Africa, stillbirth rates remain high. To design effective interventions to reduce stillbirths, accurate determination of their aetiology is important. Conventional autopsy for accurate confirmation of cause is not acceptable or feasible in several societies in sub-Saharan Africa; minimal invasive tissue sampling (MITS), is a recently developed, less invasive alternative. In this study, we explored the acceptability of MITS in the community and among healthcare workers in Uganda to guide the future implementation.
MethodsA qualitative study was done among community members and healthcare workers in Mbale in Eastern Uganda. We undertook in-depth interviews and focus group discussions in English or local languages. Interviews were audio-recorded, transcribed as necessary prior to formal content analysis. The themes were organised using NVivo software and presented according to Sekhon’s theoretical framework.
ResultsOverall, participants preferred the idea of MITS to conventional autopsy because of the perception that it was fast, maintained the facial appearance and kept the body intact. It was thought that the procedure would improve the detection of the cause of stillbirths, which in turn would help to prevent future stillbirths. It would also resolve conflicts in the community between community members or the women and the healthcare workers about the cause of a stillbirth. It was suggested that some community members may not approve of MITS because of their religious beliefs; the fear that the body parts may be extracted and stolen for witchcraft or organ donation; and a lack of trust in the healthcare system. To implement the procedure, it was suggested that extensive community sensitization should be done, space limitations in healthcare facilities overcome, healthcare workers should be trained and limited human resource should be addressed.
ConclusionThe implementation of MITS in Mbale, Eastern Uganda, is likely to be acceptable given sufficient training and sensitisation.
A considerable number of patients present with an upper limb impairment after stroke, which has a significant impact on daily life activities and quality of life. Currently, based on a Cochrane review, there is no high-quality evidence for any of the upper limb interventions used in routine practice. Therefore, the Jessa Hospital developed an additional arm-hand boost programme (AHA-BOOST), a novel, stratified intervention that integrates neurophysiological knowledge with an early start to optimise poststroke upper limb recovery.
This multicentre randomised controlled trial with parallel design compares AHA-BOOST with a dose-matched programme for the lower limbs. Both interventions are in addition to usual care and consist of a combination of group sessions (1 hour per day, 5 times per week) and individualised therapy (two 30 min sessions per week) provided over 4 weeks. In total, 80 subacute stroke patients will be recruited from five rehabilitation centres in Belgium and randomised to one of both interventions. Patients will be followed up until 12 months post stroke to support a cost-utility analysis and assess long-term clinical effects of the programme. Various outcomes are collected at different time points: preintervention, immediately post intervention, 3 months post intervention, 6 months post stroke and 12 months post stroke. The Action Research Arm Test is the clinical primary outcome. The secondary outcomes are: Fugl-Meyer assessment—upper extremity, Stroke Upper Limb Capacity Scale, Barthel Index, modified Rankin Scale, Stroke Impact Scale and EuroQoL 5D-5L (EQ-5D-5L). The clinical analysis includes a multivariate analysis of variance (MANOVA) analysis for comparing clinical changes between both groups and a subgroup analysis to explore the effects in different types of stroke survivors. Additionally, a process evaluation, guided by the Medical Research Council Framework, will assess key aspects of the implementation, including delivery (structures and resources), dose, reach, fidelity, adaptations, quality, mechanisms of change and the context. Both quantitative and qualitative data will be collected using the following tools during the intervention: therapy diaries for each session; video recordings of AHA-BOOST group sessions and after the intervention using: interviews with patients, therapists and management. The qualitative data will be assessed using content and thematic analysis and the quantitative data with descriptive statistics. Ultimately, in addition to the EQ-5D-5L, direct and indirect healthcare costs are collected for the health economic evaluation. A cost-utility analysis will be performed with a time horizon of 12 months post stroke comparing both therapies, and a Markov model will assess the cost-effectiveness of AHA-BOOST on a lifetime horizon. To test the robustness of the results, sensitivity and scenario analysis will be performed.
Ethical approval has been obtained by different ethical committees (UZ/KU Leuven (central committee), UZ Gent, Gasthuiszusters Antwerpen and Maria Middelares). The study will be performed in accordance with the protocol, current International Council for Harmonisation (ICH) and Good Clinical Practice (ICH-GCP) guidelines, and applicable regulatory requirements. The current approved protocol is version 5, dated 7 May 2025. Protocol amendments will be submitted to all involved ethical committees. The study results will be disseminated through peer-reviewed publications, conference presentations and stakeholder reports.
Hypertrophic scars (HTSs) result from excessive collagen accumulation and impaired wound remodelling, leading to considerable aesthetic and functional concerns. Despite the availability of various treatment strategies, their clinical success remains limited, emphasising the need for alternative approaches. Human amniotic fluid (hAF), naturally enriched with cytokines and growth factors, has emerged as a promising biological material for tissue regeneration. This study investigated the therapeutic potential of two forms of hAF—pooled-frozen and pooled-frozen gamma-irradiated—in a rat model of hypertrophic scarring. Fifteen adult male Sprague–Dawley rats were randomly assigned to receive subcutaneous injections of either saline, pooled-frozen hAF, or pooled-frozen gamma-irradiated hAF at the wound margins on days 1, 3 and 5 following the induction of hypertrophic scars via talc powder application. After 21 days, wound healing was evaluated through histological and immunohistochemical analyses. Both treatment groups demonstrated significantly improved wound healing compared to the control group. Granulation tissue formation was enhanced in the treated groups, particularly in animals receiving gamma-irradiated fluid, which also showed superior collagen remodelling characterised by aligned and mature collagen bundles. Both treatment groups demonstrated an increase in M2 macrophage density, as evidenced by elevated Arg+/CD68+ cell ratios; however, this effect was more pronounced in the gamma-irradiated group, indicating a stronger shift towards a regenerative immune profile. Enhanced reepithelialisation, increased hair follicle density and reduced scar thickness were also observed. These findings suggest that gamma-irradiated hAF provides a more effective and minimally invasive therapeutic option for modulating scar formation and improving wound healing outcomes, supporting its potential translation into clinical applications for the management of hypertrophic scars.
