Physical frailty (PF) is highly prevalent and associated with undesirable outcomes in stroke survivors aged 65 years or older. However, the long-term trajectories of PF are understudied in those older stroke survivors.
To identify PF trajectories and relative predictors associated with the PF trajectories in older stroke survivors.
This is a secondary analysis of a population-based cohort study in the United States.
Six hundred and sixty-three older stroke survivors from the National Health and Ageing Trends Study from 2015 to 2021 were included. PF was operationally assessed based on the Fried Frailty Phenotype. Trajectories were identified by group-based trajectory modelling. The associations between sociodemographic characteristics, clinical factors, symptoms, cognitive factors and PF trajectories were examined using the design-based logistic regression method.
Most older stroke survivors were 75 and older (63.32%), female (53.99%), white (80.54%) and partnered (50.64%). Two PF trajectory groups were identified (Group 1: low risk, robust; 49.47%; Group 2: high risk, deteriorating; 50.53%). Individuals were at a higher risk to be assigned to Group 2 if they were 75–84 years (adjusted odds ratio [aOR]: 2.16, 95% CI: 1.23–3.80) or 85+ years (aOR: 2.77, 95% CI: 1.52–5.04), had fair self-reported health (aOR: 2.78, 95% CI: 1.53–5.07) or poor self-reported health (aOR: 3.37, 95% CI: 1.51–7.52), had comorbidities (aOR: 8.44, 95% CI: 1.31–54.42), had breathing problems (aOR: 2.18, 95% CI: 1.18–4.02) and had balance problems (aOR: 1.70, 95% CI: 1.06–2.73).
PF trajectories in older stroke survivors were heterogeneous and were associated with age, self-rated health status, comorbidities, breathing problems and balance problems.
Early, routine, dynamic screening for stroke-related physical frailty (PF) and relative predictors might be beneficial for identifying the most vulnerable individuals. Our findings might help develop strategies to manage PF progression.
The reporting followed the STROBE guideline.
To comprehensively examine the prevailing condition of care dependence among middle-aged individuals who have experienced hemiplegia subsequent to a stroke and were currently undergoing post-acute rehabilitation. Additionally, the study sought to analyse the determinants that impacted this phenomenon.
A single-centre, cross-sectional study design.
During the period from January 2020 to October 2022, a cohort of 196 hemiplegic stroke patients, aged between 40 and 65, and within 6 months of their stroke onset, was selected from the cerebrovascular outpatient clinic at a tertiary hospital in Hangzhou. The demographic and disease-related data, care dependence level, mental state, nutrition and depression status were collected. Furthermore, all collected data were analysed by descriptive and correlative statistical methods.
The care dependence level was 51.04 ± 9.42, with an incidence of care dependence of 78.1%. Multivariate regression analysis showed that age, history of falls, physical dysfunction, chronic comorbidities, depression, nutritional status and cognitive dysfunction were influencing factors for care dependence in the participants after a stroke.
The incidence of care dependence among hemiplegic patients aged from 40 to 65 years old in the early stage after a stroke was high. Nursing staff should focus on these patients with a history of falling, physical dysfunction, comorbidity, depression status, nutritional status and cognitive dysfunction in clinical practice.
The incidence of care dependence in middle-aged hemiplegic patients following a stroke is significantly increased. Some risk factors should be assessed, monitored, and controlled by nursing staff as early as possible in order to reduce the dependence levels in post-acute rehabilitation period and improve the quality of life of hemiplegia patients.
Our study complies with the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) Checklist: cross-sectional studies (see Table S1).

Sarcopenia, a clinical syndrome primarily associated with reduced muscle mass in the elderly, has a negative impact on quality of life and survival. It can occur secondarily to other diseases such as heart failure (HF), a complex clinical syndrome with high morbidity and mortality. The simultaneous occurrence of these two conditions can worsen the prognosis of their carriers, especially in the most severe cases of HF, as in patients with reduced left ventricular ejection fraction (LVEF). However, due to the heterogeneous diagnostic criteria for sarcopenia, estimates of its prevalence present a wide variation, leading to new criteria having been recently proposed for its diagnosis, emphasizing muscle strength and function rather than skeletal muscle mass. The primary objective of this study is to evaluate the prevalence of sarcopenia and/or dynapenia in individuals with HF with reduced LVEF according to the most recent criteria, and compare the gene and protein expression of those patients with and without sarcopenia. The secondary objectives are to evaluate the association of sarcopenia and/or dynapenia with the risk of clinical events and death, quality of life, cardiorespiratory capacity, ventilatory efficiency, and respiratory muscle strength. The participants will answer questionnaires to evaluate sarcopenia and quality of life, and will undergo the following tests: handgrip strength, gait speed, dual-energy X-ray absorptiometry, respiratory muscle strength, cardiopulmonary exercise, as well as genomic and proteomic analysis, and dosage of N-terminal pro-B-type natriuretic peptide and growth differentiation factor-15. An association between sarcopenia and/or dynapenia with unfavorable clinical evolution is expected to be found, in addition to reduced quality of life, cardiorespiratory capacity, ventilatory efficiency, and respiratory muscle strength.The Health, Food, Purchases and Lifestyle (SMIL) cohort is a prospective open Danish cohort that collects electronic consumer purchase data, which can be linked to Danish nationwide administrative health and social registries. This paper provides an overview of the cohort’s baseline characteristics and marginal differences in the monetary percentage spent on food groups by sex, age and hour of the day.
As of 31 December 2022, the cohort included 11 214 users of a smartphone-based receipt collection application who consented to share their unique identification number for linkage to registries in Denmark. In 2022, the composition of the cohort was as follows: 62% were men while 24% were aged 45–55. The cohort had a median of 63 (IQR 26–116) unique shopping trips. The cohort included participants with a range of health statuses. Notably, 21% of participants had a history of cardiovascular disease and 8% had diabetes before donating receipts.
The feasibility of translating consumer purchase data to operationalisable food groups and merging with registers has been demonstrated. We further demonstrated differences in marginal distributions which revealed disparities in the amount of money spent on various food groups by sex and age, as well as systematic variations by the hour of the day. For example, men under 30 spent 8.2% of their total reported expenditure on sugary drinks, while women under 30 spent 6.5%, men over 30 spent 4.3% and women over 30 spent 3.9%.
The SMIL cohort is characterised by its dynamic, continuously updated database, offering an opportunity to explore the relationship between diet and disease without the limitations of self-reported data. Currently encompassing data from 2018 to 2022, data collection is set to continue. We expect data collection to continue for many years and we are taking several initiatives to increase the cohort.
Non-pharmacological interventions have been used in the rehabilitation of stroke survivors, but their effects on stroke survivors' quality of life (QoL) are unknown.
This review aimed to summarize the existing evidence regarding non-pharmacological interventions for QoL in stroke survivors and to evaluate the effectiveness of different types of interventions.
We systematically searched databases including PubMed, Embase, Web of Science, Cochrane Library, China National Knowledge Infrastructure, Chinese BioMedical Literature Database, China Science and Technology Journal Database, and Wanfang data from the earliest available records to March 2023. Randomized controlled trials which explored the effects of non-pharmacological interventions on QoL in stroke patients were included. The meta-analysis was conducted to evaluate the effectiveness of different interventions on QoL. The Review Manager 5.3 was used to conduct the meta-analysis and the revised Cochrane risk-of-bias tool was used to assess the methodological quality of trials.
A total of 93,245 records were identified, and 34 articles were reviewed and summarized, of which 20 articles were included in the meta-analysis. The summary of the findings of the included studies revealed fitness training, constraint-induced movement therapy (CIMT), physical exercise, music therapy (MT), and art-based interventions may have positive effects on QoL. The fitness training improved total QoL, especially in physical domains including physical functioning (mean difference [MD] = 10.90; 95% CI [7.20, 14.59]), role physical (MD = 10.63; 95% CI [6.71, 14.55]), and global health (MD = 8.76; 95% CI [5.14, 12.38]). The CIMT had a slight effect on general QoL (standardized mean difference [SMD] = 0.48, 95% CI [0.16, 0.80]), whereas significantly improved strength (MD = 8.84; 95% CI [1.31, 16.38]), activities of daily living/instrumental activities of daily living (ADL/IADL; MD = 10.42; 95% CI [2.98, 17.87]), and mobility (MD = 8.02; 95% CI [1.21, 14.83]). MT had a positive effect on the mental health domain (SMD = 0.54; 95% CI [0.14, 0.94]).
Our findings suggest that fitness training and CIMT have a significant effect on improving physical QoL, while MT has a positive effect on improving psychological QoL. Future studies may use comprehensive and multicomponent interventions to simultaneously improve the patients' physical, psychological, and social QoL.
The emergence of novel infectious diseases has amplified the urgent need for effective prevention strategies, especially ones targeting vulnerable populations such as children. Factors such as the high incidence of both emerging and existing infectious diseases, delays in vaccinations, and routine exposure in communal settings heighten children's susceptibility to infections. Despite this pressing need, a comprehensive exploration of research trends in this domain remains lacking. This study aims to address this gap by employing text mining and modeling techniques to conduct a comprehensive analysis of the existing literature, thereby identifying emerging research trends in infectious disease prevention among children.
A cross-sectional text mining approach was adopted, focusing on journal articles published between January 1, 2003, and August 31, 2022. These articles, related to infectious disease prevention in children, were sourced from databases such as PubMed, CINAHL, MEDLINE (Ovid), Scopus, and Korean RISS. The data underwent preprocessing using the Natural Language Toolkit (NLTK) in Python, with a semantic network analysis and topic modeling conducted using R software.
The final dataset comprised 509 journal articles extracted from multiple databases. The study began with a word frequency analysis to pinpoint relevant themes, subsequently visualized through a word cloud. Dominant terms encompassed “vaccination,” “adolescent,” “infant,” “parent,” “family,” “school,” “country,” “household,” “community,” “HIV,” “HPV,” “COVID-19,” “influenza,” and “diarrhea.” The semantic analysis identified “age” as a key term across infection, control, and intervention discussions. Notably, the relationship between “hand” and “handwashing” was prominent, especially in educational contexts linked with “school” and “absence.” Latent Dirichlet Allocation (LDA) topic modeling further delineated seven topics related to infectious disease prevention for children, encompassing (1) educational programs, (2) vaccination efforts, (3) family-level responses, (4) care for immunocompromised individuals, (5) country-specific responses, (6) school-based strategies, and (7) persistent threats from established infectious diseases.
The study emphasizes the indispensable role of personalized interventions tailored for various child demographics, highlighting the pivotal contributions of both parental guidance and school participation.
The study provides insights into the complex public health challenges associated with preventing and managing infectious diseases in children. The insights derived could inform the formulation of evidence-based public health policies, steering practical interventions and fostering interdisciplinary synergy for holistic prevention strategies.
Efficient discharge for stroke patients is crucial but challenging. The study aimed to develop early predictive models to explore which patient characteristics and variables significantly influence the discharge planning of patients, based on the data available within 24 h of admission.
Prospective observational study.
A prospective cohort was conducted at a university hospital with 523 patients hospitalised for stroke. We built and trained six different machine learning (ML) models, followed by testing and tuning those models to find the best-suited predictor for discharge disposition, dichotomized into home and non-home. To evaluate the accuracy, reliability and interpretability of the best-performing models, we identified and analysed the features that had the greatest impact on the predictions.
In total, 523 patients met the inclusion criteria, with a mean age of 61 years. Of the patients with stroke, 30.01% had non-home discharge. Our model predicting non-home discharge achieved an area under the receiver operating characteristic curve of 0.95 and a precision of 0.776. After threshold was moved, the model had a recall of 0.809. Top 10 variables by importance were National Institutes of Health Stroke Scale (NIHSS) score, family income, Barthel index (BI) score, FRAIL score, fall risk, pressure injury risk, feeding method, depression, age and dysphagia.
The ML model identified higher NIHSS, BI, and FRAIL, family income, higher fall risk, pressure injury risk, older age, tube feeding, depression and dysphagia as the top 10 strongest risk predictors in identifying patients who required non-home discharge to higher levels of care. Modern ML techniques can support timely and appropriate clinical decision-making.
This study illustrates the characteristics and risk factors of non-home discharge in patients with stroke, potentially contributing to the improvement of the discharge process.

This study aimed to explore digital literacy among community-dwelling older adults in urban South Korea. A semistructured interview guide was developed using the Digital Competence ( 2.0 framework, which emphasizes the competencies for full digital participation in five categories: information and data literacy, communication and collaboration, content creation, safety, and problem-solving. The data were analyzed using combined inductive and deductive content analysis. Inductive analysis identified three main categories: perceived ability to use digital technology, responses to digital technology, and contextual factors. In the results of deductive analysis, participants reported varying abilities in using digital technologies for information and data literacy, communication or collaboration, and problem-solving. However, their abilities were limited in handling the safety or security of digital technology and lacked in creating digital content. Responses to digital technology contain subcategories of perception (positive or negative) and behavior (trying or avoidance). Regarding contextual factors, aging-related physical and cognitive changes were identified as barriers to digital literacy. The influence of families or peers was viewed as both a facilitator and a barrier. Our participants recognized the importance of using digital devices to keep up with the trend of digitalization, but their digital literacy was mostly limited to relatively simple levels. Background
Living with two or more chronic conditions simultaneously—known as multimorbidity—has become increasingly prevalent as the aging population continues to grow. However, the factors that influence the development of multimorbidity are still not fully understood.
Objectives
The purpose of this study was to investigate the prevalence of multimorbidity among U.S. adults 50 years and older and identify associated factors with multimorbidity.
Methods
We used data from four cycles from the National Health and Nutrition Examination Survey (2011–2018) to examine the associations between social determinants of health and multimorbidity among American adults aged 50 years and older. A set of variables on socioeconomic status and health behaviors was chosen based on the social determinants of health conceptual framework developed by the World Health Organization. In our study, 4,552 participants were included. All analyses were accounted for a complex survey design and the use of survey weights. Multiple logistic regression analyses were performed to examine the associated factors with multimorbidity.
Results
The average age was 63.1 years, and 52.9% were female. The average number of chronic conditions was 2.27. The prevalence of multimorbidity was 63.8%, with high cholesterol and hypertension being the most prevalent conditions. In the adjusted model, age, gender, household income, citizenship status, health insurance, healthcare access, body mass index, and smoking status were found to be associated with living with multimorbidity.
Discussion
Our results indicate that continued efforts aimed at promoting smoking cessation and maintaining a healthy weight will be beneficial in preventing the onset of chronic conditions. Additional research is warranted to gain a deeper understanding of the interrelationships between gender, race/ethnicity, household income, citizenship status, health insurance, and healthcare access as social determinants of health in the context of multimorbidity. Further research will help us develop targeted interventions and policies to address disparities and improve health outcomes for individuals with multimorbidity. This research is intended to evaluate the efficacy of percutaneous vertebroplasty (PVP) versus percutaneous kyphoplasty (PKP) in osteoporotic vertebral compression fracture (OVCF), which is associated with post-operative pain. Eligible studies were screened by searching multiple databases and sources such as PubMed, Cochrane and EMBASE for search terms updated to October 2023, and relevant literature sources were searched. Randomized, controlled, prospective or retrospective, and cohort studies were eligible. For the analysis of the primary results, an analysis of the data was carried out, such as mean difference (MD) or odds ratio (OR), and 95% confidence interval (CI). In the present research, 1933 research was screened in 4 databases, and 30 articles were chosen to be examined under strict exclusion criteria. No statistical significance was found in the use of bone cement in the PVP group and PKP (MD, −0.60; 95% CI, −1.40, 0.21, p = 0.15); PKP was associated with a reduced risk of cement leak compared with PVP group (OR, 2.18; 95% CI, 1.38, 3.46, p = 0.0009); no statistical significance was found in the wound VAS score in PVP operation compared with that of PKP (MD, 0.16; 95% CI, −0.07, 0.40, p = 0.17); no statistical significance was found between the time of PVP operation and the time of PKP operation (MD, −2.65; 95% CI, −8.91, 3.60, p = 0.41). Compared with PVP technology, the PKP treatment of osteoporotic vertebral compression fractures reduces post-operative cement leakage, but there is no significant difference in the number of operative cement and wound VAS after operation. Nor did there appear to be a statistically significant difference in time between the two operations.
This study analyses the effects of a continuous quality improvement nursing model on wound pain at the arteriovenous fistula (AVF) puncture site in patients undergoing haemodialysis. Forty haemodialysis patients from the First Affiliated Hospital of Chongqing Medical University, from September 2020 to December 2022, were selected as study subjects. They were randomly divided into an observation group and a control group. The control group received conventional nursing care, while the observation group was treated with a continuous quality improvement nursing model. The study compared the impact of these nursing approaches on pain intensity post-AVF puncture, wound visual analogue scale scores, self-rating anxiety scale, self-rating depression scale, quality of life scores and patient satisfaction with nursing care. In the observation group, the proportion of patients experiencing moderate to severe pain during AVF puncture was lower than that in the control group, whereas the proportion of patients with no pain or mild pain was higher (P = 0.008). After nursing, the observation group exhibited significantly lower wound visual analogue scale scores, self-rating anxiety scale scores, and self-rating depression scale scores compared to the control group (P < 0.001), with a significantly higher quality of life score (P < 0.05). The nursing satisfaction rate was 95.00% in the observation group, significantly higher than the 65.00% in the control group (P = 0.018). The continuous quality improvement nursing model significantly reduces wound pain at the AVF puncture site in haemodialysis patients, alleviates negative emotions, enhances the quality of life, and achieves high patient satisfaction. It is thus a highly recommendable approach in nursing practice.
The aim of this study is to develop a nomogram to assess the risk of surgical site infection in elderly patients undergoing open lumbar spine surgery and explore related risk factors. We reviewed the records of 578 elderly patients who had undergone open lumbar spine surgery. The clinical parameters were subjected to lasso regression and logistic regression analyses. Subsequently, a nomogram was constructed to predict the risk of postoperative surgical site infection and validated using bootstrap resampling. A total of 578 patients were included in the analysis, of which 17 were diagnosed as postoperative surgical site infection. Following the final logistic regression analysis, obesity, hypoalbuminemia and drinking history were identified as independent risk factors and subsequently incorporated into the nomogram. The nomogram demonstrated excellent discrimination, with an area under the receiver-operating characteristic curve of 0.879 (95% CI 0.769 ~ 0.989) after internal validation. The calibration curve exhibited a high level of consistency. Decision curve analysis revealed that this nomogram had greater clinical value when the risk threshold for surgical site infection occurrence was >1% and <89%. We had developed a nomogram for predicting the risk of postoperative surgical site infection in elderly patients who had undergone open lumbar spine surgery. Validation using bootstrap resampling demonstrated excellent discrimination and calibration, indicating that the nomogram may hold potential clinical utility as a simple predictive tool for healthcare professionals.
Venous leg ulcer (VLU) is the most severe manifestations of chronic venous disease, which has characterized by slow healing and high recurrence rates. This typically recalcitrant and recurring condition significantly impairs quality of life, prevention of VLU recurrence is essential for helping to reduce the huge burden of patients and health resources, the purpose of this scoping review is to analyse and determine the intervention measures for preventing recurrence of the current reported, to better inform healthcare professionals and patients. The PubMed, Embase, Web of Science, Cochrane Library databases, Chinese National Knowledge Infrastructure (CNKI), Chinese Biomedical Literature Database (CBM), Wan Fang Data and Chongqing VIP Information (CQVIP) were accessed up to June 17, 2023. This scoping review followed the five-steps framework described by Arksey and O'Malley and the PRISMA extension was used to report the review. Eleven articles were included with a total of 1503 patients, and adopted the four effective measures: compression therapy, physical activity, health education, and self-care. To conclude, the use of high pressure compression treatment for life, supplementary exercise therapy, and strengthen health education to promote self-care are recommended strategies of VLU prevention and recurrence. In addition, the importance of multi-disciplinary teams to participate in the care of VLU in crucial.
The research was conducted to examine the correlation between nutritional status and wound healing in individuals who were receiving treatment for head and neck cancer. Specifically, this study sought to identify crucial nutritional factors that influenced both the recovery process and efficacy of the treatment. From February 2022 to September 2023, this cross-sectional study was undertaken involving 300 patients diagnosed with head and neck cancer who were treated at Tianjin Medical University Cancer Institute and Hospital, Tianjin, China. In order to evaluate nutritional status, body mass index (BMI), serum protein levels and dietary intake records were utilized. The assessment of wound healing was conducted using established oncological wound healing scales, photographic documentation and clinical examinations. After treatment, we observed a noteworthy reduction in both BMI (p < 0.05) and serum albumin levels (p < 0.05). There was slightly increased prevalence of head and neck cancer among males (61.0%, p < 0.05). Over the course of 6 months, significant enhancement in wound healing scores was noted, exhibiting overall improvement of 86% in the healing process. An inverse correlation was identified between nutritional status and wound healing efficacy through multivariate analysis. A logistic regression analysis revealed a significant positive correlation (p < 0.05) between elevated levels of serum protein and total lymphocytes and enhanced wound healing. Conversely, negative correlation (p < 0.05) was observed between larger wound size at baseline and healing. The research findings indicated noteworthy association between malnutrition and impaired wound repair among individuals diagnosed with head and neck cancer. The results underscored the significance of integrating nutritional interventions into therapeutic protocol in order to enhance clinical results. This research study provided significant contributions to the knowledge of intricate nature of head and neck cancer management by advocating for multidisciplinary approach that incorporates nutrition as the critical element of patient care and highlighted the importance of ongoing surveillance and customized dietary approaches in order to optimize wound healing and treatment efficacy.
Pediatric otolaryngology surgeries are crucial interventions requiring careful consideration of surgical methods to optimize outcomes. The choice between open and minimally invasive surgical approaches in this context warrants thorough investigation. While both methods aim to address ear, nose, and throat conditions in children, a comparative study assessing their impact on crucial factors such as intraoperative parameters, wound healing, complications, and postoperative pain is essential. This study aims to compare the effects of open and minimally invasive surgical methods on wound healing and infection in pediatric otolaryngology surgery, and provide a scientific basis for the selection of surgical methods. Two groups of patients were selected, with 90 people in each group. One group received open surgery and the other received minimally invasive surgery. Recording the intraoperative time, anesthesia time, and intraoperative blood loss; the number of days required for wound healing; the occurrence of wound-related complications; the comparison of pain on postoperative Days 1, 3, and 7; and the factors influencing postoperative wound healing were analyzed. In the minimally invasive surgery group, the intraoperative time was shorter, the anesthesia time was relatively reduced, and the amount of bleeding was significantly reduced. Wounds also take fewer days to heal and have lower rates of wound-related complications. When comparing the pain on 1, 3, and 7 days after surgery, the minimally invasive surgery group had relatively mild pain. Analysis of postoperative wound healing factors showed that minimally invasive surgical methods have a positive impact on healing. In pediatric otolaryngology surgery, minimally invasive surgery performs better than open surgery in terms of intraoperative operation time, anesthesia time, blood loss, wound healing time, complication rate, and postoperative pain. Therefore, minimally invasive surgery may be a safer and more effective surgical method.
This paper examined the magnitude of differences in performance across domains of cognitive functioning between participants who attrited from studies and those who did not, using data from longitudinal ageing studies where multiple cognitive tests were administered.
Individual participant data meta-analysis.
Data are from 10 epidemiological longitudinal studies on ageing (total n=209 518) from several Western countries (UK, USA, Mexico, etc). Each study had multiple waves of data (range of 2–17 waves), with multiple cognitive tests administered at each wave (range of 4–17 tests). Only waves with cognitive tests and information on participant dropout at the immediate next wave for adults aged 50 years or older were used in the meta-analysis.
For each pair of consecutive study waves, we compared the difference in cognitive scores (Cohen’s d) between participants who dropped out at the next study wave and those who remained. Note that our operationalisation of dropout was inclusive of all causes (eg, mortality). The proportion of participant dropout at each wave was also computed.
The average proportion of dropouts between consecutive study waves was 0.26 (0.18 to 0.34). People who attrited were found to have significantly lower levels of cognitive functioning in all domains (at the wave 2–3 years before attrition) compared with those who did not attrit, with small-to-medium effect sizes (overall d=0.37 (0.30 to 0.43)).
Older adults who attrited from longitudinal ageing studies had lower cognitive functioning (assessed at the timepoint before attrition) across all domains as compared with individuals who remained. Cognitive functioning differences may contribute to selection bias in longitudinal ageing studies, impeding accurate conclusions in developmental research. In addition, examining the functional capabilities of attriters may be valuable for determining whether attriters experience functional limitations requiring healthcare attention.
To examine the voluntariness of consent in paediatric HIV clinical trials and the associated factors.
Mixed-methods, cross-sectional study combining a quantitative survey conducted concurrently with indepth interviews.
From January 2021 to April 2021, we interviewed parents of children on first-line or second-line Anti-retroviral therapy (ART) in two ongoing paediatric HIV clinical trials [CHAPAS-4 (ISRCTN22964075) and ODYSSEY (ISRCTN91737921)] at the Joint Clinical Research Centre Mbarara, Uganda.
The outcome measures were the proportion of parents with voluntary consent, factors affecting voluntariness and the sources of external influence. Parents rated the voluntariness of their consent on a voluntariness ladder. Indepth interviews described participants’ lived experiences and were aimed at adding context.
All 151 parents randomly sampled for the survey participated (84% female, median age 40 years). Most (67%) gave a fully voluntary decision, with a score of 10 on the voluntariness ladder, whereas 8% scored 9, 9% scored 8, 6% scored 7, 8% scored 6 and 2.7% scored 4. Trust in medical researchers (adjusted OR 9.90, 95% CI 1.01 to 97.20, p=0.049) and male sex of the parent (adjusted OR 3.66, 95% CI 1.00 to 13.38, p=0.05) were positively associated with voluntariness of consent. Prior research experience (adjusted OR 0.31, 95% CI 0.12 to 0.78, p=0.014) and consulting (adjusted OR 0.25. 95% CI 0.10 to 0.60, p=0.002) were negatively associated with voluntariness. Consultation and advice came from referring health workers (36%), spouses (29%), other family members (27%), friends (15%) and researchers (7%). The indepth interviews (n=14) identified the health condition of the child, advice from referring health workers and the opportunity to access better care as factors affecting the voluntariness of consent.
This study demonstrated a high voluntariness of consent, which was enhanced among male parents and by parents’ trust in medical researchers. Prior research experience of the child and advice from health workers and spouses were negatively associated with the voluntariness of parents’ consent. Female parents and parents of children with prior research experience may benefit from additional interventions to support voluntary participation.
Evidences have demonstrated the effectiveness of early essential newborn care. However, the implementation of early essential newborn care is suboptimal. The aim is to identify and synthesise the barriers and facilitators impacting the implementation of early essential newborn care in low- and middle-income countries.
PubMed, EMBASE, Cochrane Central Register of Controlled Trials, PsycINFO, CINAHL, CNKI, Wan Fang Data, SinoMed and Google Scholar.
Two authors independently screened, performed quality assessment using the Mixed Methods Appraisal Tool and extracted data. This review includes papers that reported the barriers and facilitators of implementing early essential newborn care in low- and middle-income countries from the view of healthcare providers. Barriers and facilitators were coded according to the consolidated framework for implementation research in a deductive way and then been inducted into five common themes. This review followed synthesis without meta-analysis reporting guideline.
A total of 28 studies were included. Five inductive common themes influencing implementing early essential newborn care in low- and middle-income countries were system-level healthcare factors, healthcare providers’ knowledge and beliefs, the requirements of mothers or families, adapting to routine practice and the working climate of organisation.
The factors were from system level, facility level and individual level and were inducted into five themes. Based on this review, decision-makers could tailor implementing strategies to narrow the gap between the evidence and implementation.
The study offers guidance for health professionals to identify barriers and facilitators in implementing early essential newborn care and make tailored strategies when implementing early essential newborn care.

Keloids, pathological scars resulting from skin trauma, have traditionally posed significant clinical management challenges due to their persistence and high recurrence rates. Our research elucidates the pivotal roles of lipids and their derivatives in keloid development, driven by underlying mechanisms of abnormal cell proliferation, apoptosis, and extracellular matrix deposition. Key findings suggest that abnormalities in arachidonic acid (AA) synthesis and non-essential fatty acid synthesis are integral to keloid formation. Further, a complex interplay exists between lipid derivatives, notably butyric acid (BA), prostaglandin E2 (PGE2), prostaglandin D2 (PGD2), and the regulation of hyperfibrosis. Additionally, combinations of docosahexaenoic acid (DHA) with BA and 15-deoxy-Δ12,14-Prostaglandin J2 have exhibited pronounced cytotoxic effects. Among sphingolipids, ceramide (Cer) displayed limited pro-apoptotic effects in keloid fibroblasts (KFBs), whereas sphingosine 1-phosphate (S1P) was found to promote keloid hyperfibrosis, with its analogue, FTY720, demonstrating contrasting benefits. Both Vitamin D and hexadecylphosphorylcholine (HePC) showed potential antifibrotic and antiproliferative properties, suggesting their utility in keloid management. While keloids remain a prevalent concern in clinical practice, this study underscores the promising potential of targeting specific lipid molecules for the advancement of keloid therapeutic strategies.
