<i>Toxoplasma gondii</i> seropositivity among patients with sickle cell disease: Prevalence and association with blood transfusion history

by Verner N. Orish, Renosten E. Tetteh, David Adzah, Chinecherem A. Ndiokwelu, Emmanuel A. Allotey, Evans A. Yeboah, Sylvester Y. Lokpo, Kenneth Ablordey, Duneeh R. Vikpebah, Ekene K. Nwaefuna, Precious K. Kwadzokpui, Noble D. Dika, Elom Y. Dzefi, Kokou H. Amegan-Aho, Aninagyei Enoch, Senyo Tagboto

Background

Toxoplasma gondii (T. gondii) is a successful protozoan parasite infecting up to a third of the human population. It has varied transmission routes including ingestion of food and water contaminated by cat feces containing oocysts of the parasite and ingestion of bradyzoites in poorly cooked meat. Blood transfusion is another possible route of transmission especially among people with medical conditions requiring blood transfusion, such as those with sickle cell disease (SCD). This study aimed at finding out the prevalence of T. gondii infection and the association of blood transfusion among patients with SCD.

Method

This study was a cross-sectional study involving SCD patients attending the SCD clinic at the Ho Teaching Hospital in the Volta Region of Ghana. Questionnaire administration was employed to obtain sociodemographic information, cat ownership, consumption of poorly cooked meat, as well as blood transfusion history. A blood sample was collected and anti-T. gondii IgG and IgM were detected using Rapid Diagnostic Test (RDT), while Enzyme-linked Immunosorbent Assay (ELISA) was used as the gold standard and reference. Seropositivity was defined as either positive for IgG, IgM or both. Data was analyzed using SPSS version 23, with frequency distribution done for the sociodemographic variables and the prevalence of RDT and ELISA anti-T. gondii IgG and IgM. Pearson Chi-square analysis was performed to find any significant association between diagnosis of T. gondii infection with sociodemographic variables and blood transfusion. Logistic regression analysis was performed to investigate the odds of seropositivity (ELISA) with sociodemographic variables and blood transfusion.

Results

A total of 156 SCD patients participated in this study of which 124 (79.5%) and 32(20.5%) were HbSS and HbSC respectively. Among the study participants, 105 (67.3%) had a history of blood transfusion. A total of 60 (38.5%) and 83 (53.2%) patients were positive for RDT and ELISA respectively. No significant association was seen between T. gondii diagnosis and cat ownership (RDT,20[37.7%], p = 0.891; ELISA, 27[50.9%], p = 0.673) and consumption of poorly cooked meat (RDT,37[41.6%],p = 0.370;ELISA,53[59.6%], p = 0.211). However there was a significant association between T. gondii diagnosis and age, with seropositive results predominantly seen among older patients (≥20 years) (RDT, 38[52.1%], p = 0.002; ELISA 49 [67.1%, p = 0.002]. Blood transfusion had a significant association with T.gondii diagnosis (RDT, p = 0.003; ELISA, p = 0.001). A total of 66 (62.9%) of SCD patients who had history of blood transfusion tested positive for ELISA and they had 3 times the odds of testing positive for ELISA (adjusted OR 3.14[95% CI 1.50–6.58]; p = 0.002).

Conclusion

The prevalence of T. gondii infection was higher by ELISA (53.0%) than by rapid diagnostic testing (RDT) (38.5%), and sickle cell disease patients with a transfusion history had higher odds of seropositivity. These findings highlight the need to strengthen transfusion safety protocols and consider screening strategies for T. gondii among high-risk populations such as patients with sickle cell disease. Also, there is the need for longitudinal research to help elucidate the true contribution of blood transfusion transmission of T. gondii since a cross-sectional study, causality could not be established.

Factors Affecting Nurses, Midwives and Allied Health Professionals' Ability to Engage With Research

ABSTRACT

Aim

To explore factors affecting research engagement among Nurses, Midwives and Allied Health Professionals (NMAHPs) in England by examining perceptions of research capacity at organisational, team and individual levels.

Introduction

Research engagement strongly correlates with improved care quality. However, NMAHPs face persistent participation barriers compared to medical colleagues, limiting the development of a multi-professional research workforce.

Design

National descriptive cross-sectional study using a validated survey tool.

Methods

Data from NMAHPs across England were collected using the validated Research Capacity and Culture tool. Quantitative data were analysed descriptively and inferentially; qualitative free-text responses were evaluated thematically.

Results

Perceived capacity was moderate organisationally and in teams. Organisational strengths included promoting evidence-based practice (68.7%) and leadership support (61.6%). Teams offered moderate research opportunities (58.6%) but limited mentorship (47.9%). Individually, participants showed competence in literature review (69.5%) and data collection (63.4%) but required support for funding acquisition (43.8%) and publication (50.0%). Qualitatively, research was a highly valued aspect of professional identity, though participation is severely constrained by structural conditions, including extreme resource pressures, unclear career pathways, and professional inequality.

Conclusions

Despite strong motivation for evidence-based practice, significant structural barriers restrict NMAHP research engagement. Strengthening capacity demands coordinated action across clinical and policy systems, ensuring equitable access to protected time, mentorship, and vital research infrastructure.

Relevance for Clinical Practice

Supporting NMAHPs in research enhances evidence-informed decisions and service innovation. Embedding research into everyday clinical work, rather than viewing it as optional, builds a sustainable multi-professional culture.

Impact

This survey pinpoints the specific factors most strongly influencing NMAHP research engagement. It provides healthcare leaders actionable insights to build sustainable research infrastructure and inclusive clinical academic pathways.

Reporting Method

This study adhered to STROBE guidelines for cross-sectional research.

Impaired dynein function preserves spinal interneuron survival and positioning in an ALS-like mouse model

by Eleni Christoforidou, Jordan S. Rowe, Fabio A. Simoes, Raphaelle Cassel, Luc Dupuis, Peter Nigel Leigh, Majid Hafezparast

Impaired cytoplasmic dynein function has been implicated in amyotrophic lateral sclerosis (ALS) pathogenesis, yet the contributions of spinal interneurons to disease phenotypes remain unclear. We tested the hypothesis that hypomorphic dynein function in cholinergic neurons disrupts the development, survival, or positioning of inhibitory interneuron populations in the lumbar spinal cord. Using ChAT-Cre recombination, we generated four mouse genotypes with graded reductions in dynein activity in ChAT+ cells: Dync1h1+/+ (wildtype), Dync1h1−/+ (hemizygous wildtype), Dync1h1+/Loa (heterozygous Loa mutation), and Dync1h1−/Loa (hemizygous Loa). At 52 weeks of age, lumbar spinal cords (L3–L6) were harvested, cryosectioned, and immunostained for ChAT, GAD-67, Parvalbumin, and Calbindin. Cell counts were performed on confocal images from eight sections per mouse (N = 3 male mice/genotype), and radial distances from the central canal were normalised to gray matter width. Angular distributions were analysed via circular statistics. There were no significant genotype-dependent differences in the numbers of ChAT+, GAD-67+, Parvalbumin+, or Calbindin+ cells, nor in ChAT+ subpopulations (motor neurons versus interneurons) or double‐positive interneuron subsets (e.g., ChAT+–GAD-67+, Parvalbumin+–GAD-67+, Parvalbumin+–Calbindin+). Radial positioning relative to the central canal was similarly preserved across all markers and genotypes. Circular‐median tests revealed statistically significant shifts in mean angle for ChAT+, GAD-67+, and certain double‐positive cells, but these amounted to only 5–10° displacements, translating to lateral shifts of ~10–20 µm, well within single laminar bands, and are unlikely to impact circuit connectivity. Despite substantial motor deficits and hallmark TDP-43 pathology previously seen in these models, impaired dynein function does not precipitate interneuron loss or gross migratory defects in the lumbar spinal cord. Instead, our findings suggest that the primary contributions of dynein to ALS-like phenotypes likely arise from functional disruptions in axonal transport, synaptic maintenance, and neuronal physiology rather than from structural alterations or loss of interneuron populations.

Primary cilia in osteoblasts and osteocytes are required for skeletal development and mechano-adaptation

by Mariana Moraes de Lima Perini, Alyssa F. Fayemi, Julie N. Pugh, Elizabeth M. Scott, Karan Bhula, Austin Chirgwin, Olivia N. White, Nicolas F. Berbari, Jiliang Li

Primary cilia play a crucial role in the development and mechanosensation of various tissue types, including bone. In this study, we investigated their role in bone growth and adaptation by targeting two cilia specific genes, IFT88 and MKS5. Conditional knockout (cKO) of IFT88 in osteoblasts significantly reduced body weight and femur length in mice compared to the littermate controls. Additionally, female IFT88 cKO mice exhibited a significant suppression of bone formation rate compared to the littermate controls. To further explore the role of primary cilia in osteocytes, osteocytes specific MKS5 cKO mice underwent axial ulnar loading at a peak force of 2.9N for females and 3.2N for males with 120 cycles per day for three consecutive days. Load induced bone formation rate was significantly decreased by 48% in males and 42% in females compared to the littermate control mice. These findings underscore the critical role of primary cilia in bone development and mechano-adaptation. They suggest that functional primary cilia in osteoblasts are essential for skeletal development, while those in osteocytes mediates mechanically induced bone formation, highlighting its potential as therapeutic targets for bone loss prevention.

Formulation and <i>in-vitro</i> functional evaluation of a Bacillus-based multi-strain probiotic consortium relevant to protein-energy malnutrition

by Priya Mori, Ishita Modasiya, Mehul Chauhan, Hina Maniya, Vijay Kumar, Apurba Kumar Sarkar

Protein-energy malnutrition (PEM) remains a critical global health challenge, characterized by impaired nutrient absorption and chronic gut inflammation. While probiotics offer a potential therapeutic avenue, the efficacy of single-strain interventions is often limited. This study aimed to formulate and evaluate a Bacillus-based multi-strain probiotic consortium (MSPC) specifically tailored for PEM. Three strains—Bacillus spizizenii BAB 7915, Bacillus tequilensis, and Bacillus rugosus-were selected based on their non-antagonistic, synergistic growth profiles. The MSPC demonstrated superior functional attributes compared to individual strains, exhibiting significant proteolytic activity (0.52 ± 0.03 U/mL) and robust anti-inflammatory potential (5.33 ± 0.06 U/mL). Additionally, the consortium showed high tolerance to gastrointestinal conditions and strong antioxidant properties. These results suggest that the MSPC can effectively enhance protein hydrolysis and mitigate gut inflammation, providing a scientifically validated, low-cost formulation for the nutritional rehabilitation of PEM patients.

Quality of Dying Among Institutionalised Nursing Home Residents From the Caregivers' Perspective: A Mixed‐Methods Study

ABSTRACT

Aims

To examine how family caregivers of deceased nursing home residents scored and justified their ratings for each item on the Quality of Dying in Long-Term Care scale and to identify the consistencies and discrepancies between their perceptions and the scores assigned when assessing the residents' end-of-life experience.

Design

A convergent mixed-methods design, comprising a cross-sectional study and a thematic analysis for quantitative and qualitative phases, respectively.

Methods

Quantitative and qualitative data were collected simultaneously between May 2018 and February 2019. The two sets of data were analysed separately. For the quantitative component, family caregivers completed the quality of dying in long-term care scale and a single-item question assessing the final month of the residents' life. Descriptive statistics, Mann–Whitney U-tests for comparative analyses and Spearman's correlations were applied to the quantitative data, while deductive thematic analysis was conducted for the qualitative data obtained through semi-structured interviews.

Results

Sixty-nine family caregivers completed the QoD-LTC, and 11 participated in qualitative interviews. The mean overall QoD-LTC score was 39.29 (SD = 7.58). The highest-rated domain was ‘Personhood’ (M = 4.32; SD = 0.68), while the lowest was ‘Preparatory Tasks’ (M = 2.66; SD = 1.26). Interviewed family caregivers reported effective management of pain and other symptoms, satisfaction with the care provided and respectful and appropriate treatment. However, they identified significant shortcomings in communication concerning end-of-life issues, coping with death and advance care planning. Residents with cognitive impairment had significantly lower scores on the ‘closure’ (p < 0.01) and ‘preparatory tasks’ (p = 0.03) domains as well as on the overall QoD-LTC score (p = 0.01).

Conclusions and Implications

The findings demonstrate consistency between the quantitative and qualitative data, with high scores reported across most domains of the QoD-LTC scale, with the exception of the ‘Preparatory Tasks’ domain. Cognitive impairment among residents was associated with lower perceived quality of the dying process from the perspective of family members.

Clinical Relevance

Aspects related to closure and preparatory tasks were often overlooked. Strategies to enhance end-of-life communication and advance care planning are needed.

Reporting Method

The study adhered to the EQUATOR guidelines. The Mixed Methods Reporting in Rehabilitation & Health Sciences (MMR-RHS) checklist for mixed-methods studies, the STROBE checklist for cross-sectional studies, and the Consolidated Criteria for Reporting Qualitative Research (COREQ) guidelines for qualitative studies were used for reporting.

Patient or Public Contribution

No funding was received for the completion of this study.

Mobilisation Alarm Use in Hospitals and Alignment With Person‐Centred Practice: A Qualitative Study

ABSTRACT

Aim

To explore why and how staff use alarms for falls prevention in hospital and their alignment to person-centred practice.

Design

Qualitative interpretive design.

Methods

One hundred focus groups and 25 interviews across 10 health services were completed between October 2022 and September 2024. Participants included nurses (n = 451), allied health (n = 82), and fall prevention managers (n = 18). The Framework Method guided initial data familiarisation and analysis and led to the Person-Centred Practice Framework being identified as a useful framework.

Results

Themes generated: (1) Understaffed, under-resourced, under pressure, (2) Alarm impact on stress and workload, (3) Negotiating patient safety and patient preference, (4) Engaging family as a resource, (5) Sharing responsibility for alarms and falls prevention, and (6) Navigating ambiguity and fearing consequences.

Conclusion

Staff feel compelled to use alarms despite problems associated with their use and challenges to person-centred practice. Drivers of alarm use were feeling under-resourced and fearing liability if patients fell. Staff want clearer organisational guidance in alarm use but also want the freedom to use their own clinical reasoning.

Impact

Hospitals worldwide are working to identify effective strategies for preventing falls. However, research has yet to adequately explore the perspectives of frontline nurses and allied health staff regarding the use of mobilisation alarms—a critical gap when evaluating their impact and effectiveness. This study's six key themes provide insights into why alarms are so widely used despite the limited evidence supporting their effectiveness.

Reporting Method

Delayed Admission to the Intensive Care Unit Is Associated With Increased Mortality Risk in Critically Ill Patients: A Prospective Cohort Study

ABSTRACT

Aim

To examine the impact of delays in intensive care unit (ICU) admission on patient outcomes, specifically clinical deterioration and mortality among patients transferred from the emergency department (ED) or general wards following acute deterioration in an Australian public hospital.

Design & Methods

This prospective cohort study was conducted over a 12-month period (15 April 2022–14 April 2023) in a 209-bed regional hospital. It included adult patients (aged ≥ 18 years) admitted to the ICU from ED or general wards following acute deterioration. Primary outcomes measured were duration of delay in ICU admission, ICU and hospital mortality and changes in Sequential Organ Failure Assessment (SOFA) scores over time to assess organ dysfunction and progression.

Results

A total of 403 patients were included. Of these, 276 (68.5%) experienced delays in ICU admission, ranging from 25 min to 347.25 h (median: 7.13 h). Delayed ICU admission was associated with increased mortality. Each one-point increase in the highest recorded SOFA score was linked to a 7.5% rise in mortality odds, while each one-point increase in the initial or 24-h SOFA score corresponded to a 6.8% increase.

Conclusions

Delayed ICU admission was significantly associated with increased mortality, particularly in patients with elevated SOFA scores, indicating worsening organ dysfunction and clinical instability.

Implications for Practice

These findings highlight the urgent need for improved triage systems, early warning protocols and streamlined escalation pathways to expedite ICU transfers for deteriorating patients. Timely intervention is essential to reduce harm and improve outcomes.

Impact

This study reinforces the clinical risks of delayed ICU admission and supports timely escalation of care in emergency and ward settings across Australian public hospitals.

Reporting

Conducted in accordance with STROBE guidelines.

Patient/Public Contribution

No direct patient or public involvement. The study used routinely collected clinical data to evaluate systemic and clinical outcomes.

Changes in the prevalence of adolescent tobacco use and its associated factors in Indonesia: analysis of repeated cross-sectional survey 2009-2019

Por: Suryadarma · A. Y. · Saputro · S. A. · Isnuwardana · R. · Destiwi · M. · Bassey · P. E. · Martini · S. · Sebayang · S. K.
Background

Adolescent tobacco use (ATU) is a global public health concern, causing significant morbidity and premature death. This study aimed to assess trends in the prevalence of ATU in Indonesia between 2009 and 2019 and to identify factors contributing to the observed changes.

Methods

This study performed secondary data analysis of three consecutive waves (2009, 2014, and 2019) of the Indonesian Global Youth Tobacco Survey (IGYTS). Weighted prevalence estimates and complex survey data analysed using multivariate logistic regression were established across the three-wave surveys. A pooled IGYTS data set was explored to determine the risk factors of the ATU. A multivariate decomposition analysis (MDA) was used to determine factors contributing to the prevalence change in male adolescents over the last two surveys.

Results

The prevalence of ATUs was 21.1% (38.2% in males; 6.4% in females), 18.6% (32.7% in males; 3.9% in females) and 19.8% (36.8% in males; 3.5% in females) for the three consecutive surveys, respectively. Being older adolescents, male, exposed to SHS (secondhand smoke) at home, tobacco industry promotion, not knowledgeable of the dangers of tobacco smoke and SHS, and against banning smoking in public places were associated with ATU consistently across the surveys. In addition, inadequate anti-cigarette media and not being knowledgeable of the difficulty of quitting smoking were also identified as risk factors in the pooled data. MDA showed that 88.94% of the explained change was due to differences in the composition of explanatory variables between the last two surveys.

Conclusions

This study suggests that social influence and tobacco industry promotion significantly impact ATU in Indonesia. Governments should emphasise these factors in their tobacco control interventions.

Objectives

The COVID-19 pandemic threatened global HIV Test and Treat Efforts. We assessed whether it affected (1) the number of antiretroviral therapy (ART) initiations and (2) the proportion of timely ART initiations in people living with HIV (PLWH) globally.

Design

Quasi-experimental, regression discontinuity design using routinely collected data from HIV clinics.

Setting

360 HIV care clinics across primary and secondary levels of care, participating in the International epidemiology Databases to Evaluate AIDS consortium, in 31 countries in Asia, Africa and the Americas.

Participants

177 391 PLWH (≥18 years old) who initiated ART 2 years before and 1 year after the onset of the COVID-19 pandemic in their country.

Primary and secondary outcome measures

The primary outcome was the number of ART initiations per week; the secondary outcome was the proportion of timely ART initiations (ie, ART initiated within 7 days of enrolment). We assessed changes in these outcomes in the 52 weeks after compared to the 104 weeks before the pandemic onset, defined using each country’s peak Oxford Stringency Index score between January and June 2020.

Results

Among 177 391 newly enrolled PLWH, 129 743 initiated during the pre-pandemic and 47 648 post-pandemic onset. 72.5% of ART initiations were timely pre-pandemic whereas 82.3% were during the pandemic. Absolute number of ART initiations remained stable during the pandemic period in 25 of 31 countries but decreased significantly in six countries: India (–5.0 p, 95% CI –9.2 to –0.7), Rwanda (–10.0 p, –18.6 to –1.4), Malawi (–33.4 p, –54.1 to –12.3), South Africa (–130.8 p, –188.6 to –73.1), Zimbabwe (–12.9 p, –20.0 to –5.8) and Togo (–19.6 p, –39.1 to –0.1). The proportion of timely initiations was stable in all countries except in Kenya (+4.2 pp, 95% CI +0.3 to +8.1) and in Mozambique (+2.7 pp, +0.5 to +4.9), where it increased significantly.

Conclusions

A deeper understanding of the factors that contributed to sustaining ART initiations, particularly in settings with stringent public health and social measures, is needed. These insights should inform preparedness strategies, resource allocation and policy development to ensure continuity of HIV services during future health emergencies, in line with World Health Organisation recommendations.

Comparative efficacy and acceptability of non-pharmacological and pharmacological treatments in post-stroke depression: protocol for a systematic review and network meta-analysis

Por: Yao · X. · Pu · J. · Fan · Y. · Jiang · X. · Zhao · H. · Wang · Y. · Ye · Y. · Wei · Y. · Yang · L.
Introduction

Depression is a common complication of stroke that adversely affects functional recovery. Although a wide range of pharmacological and non-pharmacological interventions are used in clinical practice, evidence regarding their comparative efficacy and acceptability remains inconclusive. Therefore, we will conduct the first systematic review and network meta-analysis (NMA) to compare and rank available interventions for post-stroke depression (PSD).

Methods and analysis

The findings will be reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols guidelines. In this systematic review and network meta-analysis, we will search PubMed, EMBASE, Cochrane Central Register of Controlled Trials, PsycINFO, CINAHL, ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform from database inception to 1 September 2025 to identify published and unpublished randomised controlled trials (RCTs). We will include studies comparing pharmacological and non-pharmacological treatments, or any control conditions as monotherapy for the treatment of patients with PSD. We will assess the certainty of evidence using the Confidence in Network Meta-Analysis framework. The primary outcomes will be the change score on depression scales from baseline to the end of treatment (efficacy) and all-cause discontinuation (acceptability). Secondary outcomes will include quality of life, cognitive and neurological function scores, anxiety and sleep quality. Two reviewers will independently screen and select eligible studies based on predefined inclusion and exclusion criteria. Risk of bias in all RCTs included in the NMA will be assessed using the revised Cochrane Risk of Bias tool (RoB 2). A frequentist NMA will be conducted in Stata and R. Meta-regression and sensitivity analyses will be performed to assess robustness.

Ethics and dissemination

This NMA does not need ethical approval, as the data used here are based on aggregated data in the public domain. Findings from the analysis will provide an overview and information on the relative efficacy and acceptability of non-pharmacological and pharmacological treatments in PSD. The results will be disseminated through peer-reviewed publication.

Objectives

This study aimed to quantify how patient risk factors relate to COVID-19 severity across categories 1–5 in a prospective, hospital-based cohort. We hypothesised that greater severity would be associated with higher odds of intensive care unit (ICU) admission and in-hospital mortality. Secondary aims were to assess associations with age, viral variants, symptom clusters, lymphocyte count, fasting blood glucose and cytokine profiles.

Design

Prospective cohort study.

Setting

A secondary-care/tertiary-care hospital and linked community settings in Cheras, Kuala Lumpur, Malaysia.

Participants

This study was nested within the COVGEN project, a prospective COVID-19 cohort conducted at Hospital Canselor Tuanku Muhriz UKM (HCTM), Cheras Health Clinic and the Bandar Tun Razak COVID-19 Assessment Centre in Cheras, Kuala Lumpur, Malaysia, from 1 August 2021 to 31 October 2022. 2532 participants were enrolled at baseline. Eligible participants were Malaysian citizens aged 12–18 years (paediatric/adolescent) or ≥18 years who had reverse transcription-polymerase chain reaction–confirmed COVID-19 at recruitment and resided in Kuala Lumpur or Selangor. Patients who had a clinically unstable condition and those who declined participation (personally or via a next-of-kin or legal representative) were excluded. This analysis included 559 patients hospitalised at HCTM; after excluding five with incomplete questionnaires, 554 remained for analysis (413 admitted to general wards and 141 to ICUs). Categories 3–5 comprised hospitalised patients, whereas categories 1–2 included hospitalised individuals and a subset recruited from community settings.

Primary and secondary outcome measures

Primary outcomes included disease severity (categories 4–5 vs 1–3), ICU admission and in-hospital mortality. Secondary outcomes included associations with age strata, viral variant (delta vs omicron), symptom clusters, lymphocyte count, fasting blood glucose and cytokines: interferon gamma-inducible protein 10, interferon gamma, interleukins 8, 10, 2, 6 and 7 and tumour necrosis factor alpha.

Results

141 of 554 (25.5%) patients required ICU care. Compared with milder categories, category 5 was associated with markedly higher odds of ICU admission (OR 204.50; 95% CI 37.54 to 1114.18; p55 versus

Conclusions

An increasing clinical severity category was strongly associated with ICU admission and mortality. Age, delta infection, specific symptom clusters, lymphopenia, hyperglycaemia and pro-inflammatory cytokines identified higher-risk patients, supporting risk-stratified management and prioritisation for enhanced monitoring.

Prevalence and associated factors of health facility delivery during COVID-19 in the Tamale Metropolis of Ghana: Analytical cross-sectional study

by Obed Kwaku Duah Asumadu, Gilbert Abotisem Abiiro, Joyce Aputere Ndago, David Abatanie Kanligi, Martin Nyaaba Adokiya

Introduction

Globally, the COVID-19 pandemic significantly impacted the provision of maternal health services, especially facility-based delivery. However, there is little evidence on the proportion of women who delivered at the health facility in various locations and the factors that influenced women’s decision-making in choosing a place of delivery during and amid the COVID-19 restrictions. Therefore, this study assessed the prevalence and factors associated with health facility delivery during the COVID-19 pandemic in the Tamale Metropolis of Ghana.

Methods

An analytical cross-sectional study design was conducted. A multistage sampling technique was used in selecting the study communities. At the individual level, random sampling technique was applied, and 461 women were recruited from 21st February 2021–21st March 2021. Using a questionnaire, a face-to-face approach was used to conduct the interviews. The questionnaire included questions on socio-demographic characteristics, place of childbirth and factors that led to the choice of delivery place. Using Statistical Package for Social Sciences version 25, descriptive and binary logistic regression analysis were conducted.

Results

The results revealed that 64.0% of the women delivered in health facilities during the pandemic. Health facility delivery was more likely to occur among women with higher educational status (AOR: 5.2; 95% CI: 1.40–19.40), married women (AOR:6.3; 95% C.I:1.10–35.80), active National Health Insurance Scheme holders during delivery (AOR: 13.8; 95% C.I: 4.60–41.90), women who received education on birth preparedness and complication readiness (AOR: 7.6; 95% C.I:3.30–17.50) and women with underlying conditions before pregnancy (AOR:3.3; 95% C.I:1.20–9.20). There were reduced odds of health facility delivery among women with a history of home delivery (AOR:0.2; 95% C.I:0.10–0.50), when the mother-in-law decides on the place of delivery (AOR:0.1; 95% C.I:0.03–0.50), longer distance to the place of delivery (AOR:0.3; 95% C.I:0.01–1.00) and when women perceived COVID-19 as a barrier to facility delivery (AOR:0.1; 95% C.I:0.03–0.20).

Conclusion

Our findings show that health facility delivery declined during COVID-19. Factors that affected health facility delivery were educational status, marriage, having an active National Health Insurance Scheme, education on birth preparedness and complication readiness, underlying conditions before pregnancy, history of home delivery, mother-in-law decision on place of delivery, distance to place of delivery and perceiving COVID-19 as a barrier to facility delivery. These contributed to low facility delivery. Thus, maternal health services need to be brought to the doorsteps of communities, including proper implementation of the Focused Antenatal Care and community-based pregnancy school programmes, especially during future pandemics.

Disaggregating innovation for sustainable development in ASEAN: Panel evidence on the moderating role of government effectiveness

by Pureheart Ogheneogaga Irikefe, Mohammad Falahat, Ahmad Danial Zainudin, Ihtisham Ullah, Nohman Khan, Bernard Ojonugwa Anthony

With progress toward the 2030 Agenda faltering, many see innovation as a key to sustainable development. The Association of Southeast Asian Nations (ASEAN) bloc represents a unique opportunity to examine how innovation capabilities drive sustainability in diverse economic and developmental contexts. Using panel data for ASEAN countries from 2011 to 2022, this study breaks down innovation into the seven pillars of the Global Innovation Index (GII) and investigates their impact on the Sustainable Development Goal (SDG) Index; with the objective of identifying which GII pillars most strongly predict SDG, while examining the moderating role of government effectiveness and controlling the impacts of gross national income per capita and foreign direct investment. Fixed effects models were used to analyse the data and supplemented by Driscoll-Kraay standard errors, addressing unobserved heterogeneity and cross-sectional dependence. Results reveal that only Institutions and Infrastructure pillars exert a consistently positive impact on SDG performance. In contrast, Creative Outputs have a negative impact. Importantly, Government Effectiveness reverses the negative impact of Creative Outputs, so that this pillar becomes positive for SDG achievement, without significant moderation of the other six GII pillars when controlling for year effects. In conclusion, these findings contest the efficacy of universal innovation policies and underscore the imperative for nuanced, context‑specific ones. It is recommended that ASEAN governments prioritize institutional and infrastructural investments and develop tailored regulatory frameworks, such as green intellectual property regimes and digital economy standards, to harness the creative economy for inclusive, sustainable growth by explicitly integrating innovation strategies with governance reforms.

Introduction

The diversity of treatment options for diabetic retinopathy (DR) and the high uncertainty about the benefits and risks of different treatment modalities necessitate shared decision-making between patients and healthcare professionals. However, little is known about the involvement of individuals with DR in treatment decision-making in China. This study aims to gain insight into the current status and factors associated with involvement in treatment decision-making in patients with DR. Furthermore, we will explore the experiences and perceptions of patients with DR regarding their involvement in treatment decision-making.

Methods and analysis

We will conduct a mixed-method study using an explanatory sequential design. In the quantitative research (n=350), participants’ actual decision-making roles, sociodemographic data, disease-related data, health literacy, need for involvement in decision-making, decision-making self-efficacy, social support and ophthalmologist facilitation of patient involvement will be investigated to analyse the current state of patient involvement in treatment decision-making and the factors influencing it. Descriptive statistics, one-way analysis of variance and multinomial logistic regression will be performed. During this period, individual semistructured interviews will be conducted with a subset of these participants to understand the perceptions and experiences of people with DR regarding their involvement in treatment decision-making, and thematic analysis will be used to analyse the interview data. Finally, the joint display will be used to integrate quantitative and qualitative data.

Ethics and dissemination

Ethical approval for this study has been obtained from the Ethical Review Committee for Human Trials of Shanghai General Hospital, China (number: 2024–098). Written informed consent will be obtained from all participants after they have been fully informed about the study, prior to any data collection. The study’s findings will be disseminated through peer-reviewed publications and conference reports.

Physiological and biochemical characterization of trypsin from <i>Neocaridina denticulata sinensis</i> and its roles in ontogenesis and immune response

by Dandan Feng, Yakun Song, Zuqi Wu, Wuruo Liu, Yuting Pu, Yangcan Gao, Yuying Sun, Jiquan Zhang

Trypsin, a canonical serine protease in crustaceans, plays a crucial role in ontogeny and antibacterial defense. Whether these biological functions correlate with its catalytic characteristics remains unresolved in the freshwater shrimp Neocaridina denticulata sinensis. To address this gap, we characterized a trypsin gene from N. denticulata sinensis (NdTryp) and assessed both its biological roles and its prospective utility. NdTryp was predominantly expressed in the hepatopancreas, where it localized to storage cells (R-cells) and tubule-lining epithelial cells (ECTs). Across development, NdTryp transcripts were essentially absent during early embryogenesis but rose sharply at late stages, temporally coincident with hatching and the onset of feeding. After a challenge with Vibrio parahaemolyticus, the expression of NdTryp was induced, with the expression level significantly increased relative to the baseline expression level. RNA interference-mediated knockdown rendered shrimp more susceptible to infection and was accompanied by extensive hepatopancreatic injury, including epithelial detachment and disruption of the basement membrane. Biochemically, recombinant NdTryp (rNdTryp) displayed proteolytic activity over a broad temperature and pH span. Activity was differentially tuned by metal ions, with several divalent cations producing marked enhancement, whereas ferric iron exerted strong inhibition. Overall, our results showed that NdTryp functions as a multifunctional protease involved in both late embryonic development and innate antimicrobial defense. Furthermore, the robust stability of rNdTryp underscores its potential as an aquafeed additive and candidate for enzymatic biotransformation.

Wound Healing Property of a Novel Thermo‐Reversible Wound Gel With Lasting Antimicrobial and Antibiofilm Activity

ABSTRACT

This study investigated the efficacy and safety of a novel thermo-reversible antimicrobial wound gel (TRG, revyve Antimicrobial Wound Gel) designed to combat biofilm-related infections in wounds. The TRG was evaluated for its ability to disrupt biofilms, sustain antimicrobial activity and promote wound healing. The gel exhibited thermo-reversible properties, transitioning from a less viscous liquid ≤ 18°C to a highly viscous solid gel at wound temperature which would facilitate easy application and removal. Antimicrobial testing demonstrated that TRG effectively inactivated a broad range of wound-related pathogens, including Staphylococcus aureus and Pseudomonas aeruginosa, with a 99.99%–99.9999% reduction in bacterial counts within 30 min. The TRG also maintained its antimicrobial efficacy after multiple inoculations with high microbial load (107 CFU/mL) over 7 days. In vitro biofilm assays showed effectiveness against biofilm bacteria with a reduction of ≥ 99.99% bacterial counts with one application over the course of 7 days. Biocompatibility testing confirmed that TRG was safe, with no signs of tissue necrosis or signs of tissue damage and no impact on wound healing in a porcine wound model. TRG's ability to reduce both planktonic and biofilm-based bacteria without compromising wound healing makes it a promising candidate for treating both chronic and acute wounds.
