This Phase 1b study was designed to evaluate the safety and efficacy of pravibismane, a novel broad-spectrum topical anti-infective, in managing moderate or severe chronic diabetic foot ulcer (DFU) infections. This randomized, double-blind, placebo-controlled, multicenter study consisted of 39 individuals undergoing pravibismane treatment and 13 individuals in the placebo group. Assessment of safety parameters included clinical observations of tolerability and pharmacokinetics from whole blood samples. Pravibismane was well-tolerated and exhibited minimal systemic absorption, as confirmed by blood concentrations that were below the lower limit of quantitation (0.5 ng/mL) or in the low nanomolar range, which is orders of magnitude below the threshold of pharmacological relevance for pravibismane. Pravibismane treated subjects showed approximately 3-fold decrease in ulcer size compared to the placebo group (85% vs. 30%, p = 0.27). Furthermore, the incidence of ulcer-related lower limb amputations was approximately 6-fold lower (2.6%) in the pooled pravibismane group versus 15.4% in the placebo group (p = 0.15). There were no treatment emergent or serious adverse events related to study drug. The initial findings indicate that topical pravibismane was safe and potentially effective treatment for improving recovery from infected chronic ulcers by reducing ulcer size and facilitating wound healing in infected DFUs (ClinicalTrials.gov Identifier NCT02723539).
The objective of this study is to explore the information needs related to insulin therapy in children and adolescents with type 1 diabetes mellitus (T1DM) from the children’s perspectives as well as their caregivers.
Qualitative study; semistructured interviews. To identify emerging themes relating to information needs, open coding and thematic analysis were employed.
Participants were recruited from a tertiary care children’s hospital in Kuala Lumpur, Malaysia and a specialist hospital in Riyadh, Saudi Arabia.
Thirty one children with a mean age of 11.5 years (SD=1.9) and their caregivers were interviewed. Seventeen participants were from Malaysia and 14 were from Saudi Arabia.
Four themes of information emerged from the interviews, including information related to (1) hypoglycaemia and hyperglycaemia, (2) insulin therapy, (3) injection technique and (4) other information needs pertaining to continuous glucose monitoring, access to peer groups and future advances in insulin therapy.
This study provided valuable insights into the information needs related to T1DM and insulin therapy among children and adolescents with T1DM that should be considered by stakeholders in the development of age-appropriate education materials. Such materials will assist children and adolescents to better manage their life-long T1DM condition from adolescence until adulthood.
Hyperbaric oxygen therapy (HBOT) has been used in patients with diabetic foot ulcers (DFU) for many years, but its clinical efficacy is still controversial. Therefore, this study explored the efficacy of HBOT applied to DFU by means of meta-analysis. PubMed, Cochrane Library, Embase, CNKI and Wanfang databases were searched, from database inception to October 2023, and published randomised controlled trials (RCTs) of HBOT in DFU were collected. Two investigators independently screened the collected literature, extracted relevant data and assessed the quality of the literature. Review Manager 5.4 software was applied for data analysis. Twenty-nine RCTs with 1764 patients were included. According to the combined results, when compared with conventional treatment, HBOT significantly increased the complete healing rate of DFUs (46.76% vs. 24.46%, odds ratio [OR]: 2.83, 95% CI: 2.29–3.51, p < 0.00001) and decreased the amputation rate (26.03% vs. 45.00%, OR: 0.41, 95% CI: 0.18–0.95, p = 0.04), but the incidence of adverse events was significantly higher in patients (17.37% vs. 8.27%, OR: 2.49, 95% CI: 1.35–4.57, p = 0.003), whereas there was no significant difference in the mortality (6.96% vs. 12.71%, OR: 0.52, 95% CI: 0.21–1.28, p = 0.16). Our results suggest that HBOT is effective in increasing the complete healing rate and decreasing the amputation rate in patients with DFUs, but increases the incidence of adverse events, while it has no significant effect on mortality.

Developing precise species-specific in vitro models that closely resemble in vivo intestinal tissues is essential for advancing our understanding of gastrointestinal physiology and associated diseases. This is especially crucial in examining host-pathogen interactions, particularly in bovines, a known reservoir for microbes and pathogens posing substantial public health threats. This research investigated the viability of producing bovine rectal organoids from cryopreserved tissues. We compared two cryopreservation methods with a traditional technique using fresh tissues, evaluating their effectiveness through growth rates, long-term viability, and comprehensive structural, cellular, and genetic analyses. These assessments utilized phase-contrast imaging, immunofluorescence imaging, and RT-qPCR assays. Additionally, the study developed a sophisticated method for forming a functional epithelial barrier from organoid-derived bovine rectal monolayers, incorporating a wide range of epithelial cells. This methodology employed transepithelial electrical resistance (TEER), parallel artificial membrane permeability assay (Papp), confocal microscopy, and advanced imaging techniques like scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Our findings decisively show that bovine rectal organoids can be effectively generated from cryopreserved biopsy tissues. Moreover, we formulated a robust and optimized protocol for creating functional rectal monolayers from these organoids. This significant progress is particularly relevant given the susceptibility of the bovine rectum to various enteric pathogens of public health concern, marking a vital step forward in veterinary and biomedical research. The creation of accurate species specific in vitro models that faithfully mimic in vivo intestinal tissues is critical for enhancing our understanding of gut physiology and related pathologies. This is particularly relevant in studying the interactions between hosts and microbes or pathogens with significant public health risks where bovine can be the major reservoir.by Yiming Li, Jianfu Li, Jianping He, Cui Tao
Though Vaccines are instrumental in global health, mitigating infectious diseases and pandemic outbreaks, they can occasionally lead to adverse events (AEs). Recently, Large Language Models (LLMs) have shown promise in effectively identifying and cataloging AEs within clinical reports. Utilizing data from the Vaccine Adverse Event Reporting System (VAERS) from 1990 to 2016, this study particularly focuses on AEs to evaluate LLMs’ capability for AE extraction. A variety of prevalent LLMs, including GPT-2, GPT-3 variants, GPT-4, and Llama2, were evaluated using Influenza vaccine as a use case. The fine-tuned GPT 3.5 model (AE-GPT) stood out with a 0.704 averaged micro F1 score for strict match and 0.816 for relaxed match. The encouraging performance of the AE-GPT underscores LLMs’ potential in processing medical data, indicating a significant stride towards advanced AE detection, thus presumably generalizable to other AE extraction tasks.by Jinkun Li, Jingmin Zhang, Shuo Tao, Xiaoying Zeng, Rong Zou, Xiaobin Hong
In the artistic sports program, the referee’ scores directly determine the final results of the athletes. Wushu is a artistic sport that has a Chinese characteristic and has the potential to become an official competition at the Summer Olympic. In this study we tested whether a red uniform color affects Wushu Routine practitioners’ ratings of athletes’ position or movement of Wushu Routine. We also tested whether the effect varied depending on the gender of the athlete and the practitioner, and depending on whether female practitioners were in the ovulation phase of their menstrual cycle. Male (Experiment 1: N = 72) and female (Experiment 1: N = 72; Experiment 2: N = 52) participants who major in Wushu Routine were recruited to take a referee’s perspective and rate the movement quality of male and female athletes wearing red or blue uniforms. The results of Experiment 1 showed that both male and female athletes wearing red uniform (compared to blue uniform) received higher ratings (p = .002, η2 = .066; p = .014, η2 = .043), and the red effect was especially strong when male practitioners rated female athletes (p = .002, η2 = .069). The results of Experiment 2, in an all-female sample, showed that in most cases there was no difference in ratings made by women in the ovulation and non-ovulation phases of their menstrual cycle, with the exception of their ratings of male athletes wearing red; in this condition, women gave higher ratings when they were in the ovulation phase of their cycle (p = .026). The results suggest that there is a red effect in an artistic sport like Wushu Routine, in which gender and the female menstrual cycle play an important role.To estimate the potential impact of expanding services offered by the Joint Effort for Elimination of Tuberculosis (JEET), the largest private sector engagement initiative for tuberculosis (TB) in India.
We developed a mathematical model of TB transmission dynamics, coupled with a cost model.
Ahmedabad and New Delhi, two cities with contrasting levels of JEET coverage.
Estimated patients with TB in Ahmedabad and New Delhi.
We investigated the epidemiological impact of expanding three different public–private support agency (PPSA) services: provider recruitment, uptake of cartridge-based nucleic acid amplification tests and uptake of adherence support mechanisms (specifically government supplied fixed-dose combination drugs), all compared with a continuation of current TB services.
Our results suggest that in Delhi, increasing the use of adherence support mechanisms among private providers should be prioritised, having the lowest incremental cost-per-case-averted between 2020 and 2035 of US$170 000 (US$110 000–US$310 000). Likewise in Ahmedabad, increasing provider recruitment should be prioritised, having the lowest incremental cost-per-case averted of US$18 000 (US$12 000–US$29 000).
Results illustrate how intervention priorities may vary in different settings across India, depending on local conditions, and the existing degree of uptake of PPSA services. Modelling can be a useful tool for identifying these priorities for any given setting.
Young people aged 18–24 years old are a key demographic target for eliminating HIV transmission globally. Pre-exposure prophylaxis (PrEP), a prevention medication, reduces HIV transmission. Despite good uptake by gay and bisexual men who have sex with men, hesitancy to use PrEP has been observed in other groups, such as young people and people from ethnic minority backgrounds. The aim of this study was to explore young people’s perceptions and attitudes to using PrEP.
A qualitative transcendental phenomenological design was used.
A convenience sample of 24 young people aged between 18 and 24 years was recruited from England.
Semistructured interviews and graphical elicitation were used to collect data including questions about current experiences of HIV care, awareness of using PrEP and decision-making about accessing PrEP. Thematic and visual analyses were used to identify findings.
Young people had good levels of knowledge about HIV but poor understanding of using PrEP. In this information vacuum, negative stigma and stereotypes about HIV and homosexuality were transferred to using PrEP, which were reinforced by cultural norms portrayed on social media, television and film—such as an association between using PrEP and being a promiscuous, white, gay male. In addition, young people from ethnic minority communities appeared to have negative attitudes to PrEP use, compared with ethnic majority counterparts. This meant these young people in our study were unable to make decisions about when and how to use PrEP.
Findings indicate an information vacuum for young people regarding PrEP. A strength of the study is that theoretical data saturation was reached. A limitation of the study is participants were largely from Northern England, which has low prevalence of HIV. Further work is required to explore the information needs of young people in relation to PrEP.
Breast cancer survivors (BCSs) are often faced with multiple mental and physical sequelae and are at increased risk of emotional distress, degraded health-related quality of life (HRQoL), chronic pain and fatigue.
Physical activity is strongly associated with improved HRQoL and survival rates; however, adherence rates to recommendations for a healthy lifestyle are seldom satisfactory among BCSs. Also, few studies have examined the effectiveness of multicomponent and personalised interventions that integrate physical activity and motivational techniques to improve the HRQoL of BCS.
"Activité physique adaptée Doublée d’un Accompagnement d’après cancer" (ADA) is an integrated programme of physical activity enriched with a dietary and supportive care approach targeting BCS in the early post-treatment phase. The effectiveness of the ADA intervention will be evaluated using a cluster randomised controlled trial design with two arms (ADA programme vs usual care; 1:1 ratio).
The ADA intervention aims to recruit 160 participants and will be implemented by Siel Bleu, a non-profit association specialised in health prevention via adapted physical activity. Measurements will be performed at baseline, 3, 6 and 12 months after the start of the intervention. The primary outcome will be participants’ HRQoL, at 12 months measured by the Functional Assessment of Chronic Illness Therapy-Fatigue global score. Secondary outcome will include participants’ physical, social, emotional and functional well-being. The effect of the intervention on physical activity level, motivation for physical activity, relation to food and self-efficacy will also be evaluated.
The study was approved by the ‘CPP Paris XI’ Institutional Review Board on 5 May 2022 (Ref no.: 21.04512.000048-22004). The study’s findings will be shared through various channels, including academic publications, simplified reports for wider audiences and active engagement with medical and institutional organisations as well as patients’ associations.
To analyse the content of letters written by female spouse primary caregivers of patients with glioblastoma multiforme (GBM), a devastating and terminal primary brain cancer, and give voice to their experiences for medical providers of patients with GBM.
A qualitative study using reflexive thematic analysis of letters written by female spouses/life partners and primary caregivers of patients with GBM.
101 current or former female spouse primary caregivers of patients with GBM wrote letters to share with the medical community between July 2019 and August 2019. Inclusion criteria: (1) the primary caregiver who is a spouse of a patient with glioblastoma, (2) be a member of the secret Facebook group, ‘We are the wives of GBM and this is our story’, and (3) completed informed consent for the contents of their letter to be included for primary and secondary data analysis. Participants who wrote letters but did not complete the informed consent were excluded from the study.
Themes from the letters included the patient experiences: (1) medical details of the disease trajectory, (2) interactions of the patient/caregiver dyads with healthcare and (3) the changing patient condition over time. Themes focused on the caregiver experiences: (1) caregiver challenges, (2) caregiver responses and (3) caregiver coping strategies, and description of tangible needs that would help other caregivers in the future. Caregiver needs were highest during the living with disease progression phase. Caregivers wanted more education and to be valued as members of the care team.
Shared decision-making through family-centred care would be beneficial for primary caregivers of patients with GBM. These findings provide opportunities to guide more timely and tailored interventions to provide support and improve care for patient/caregiver dyads to help mitigate the burden of this progressive disease and improve quality of life for caregivers.
A meta-analysis was conducted to comprehensively evaluate the impact of cluster nursing interventions on the prevention of pressure ulcers (PUs) in intensive care unit (ICU) patients. Computer searches were performed in databases including Embase, Google Scholar, Cochrane Library, PubMed, Wanfang and China National Knowledge Infrastructure for randomized controlled trials (RCTs) implementing cluster nursing interventions for PUs prevention in ICU patients, with the search period covering the database inception to November 2023. Two researchers independently screened the literature, extracted data and conducted quality assessments. Stata 17.0 software was employed for data analysis. Overall, 17 RCTs involving 1463 ICU patients were included. The analysis showed that compared with conventional nursing, cluster nursing interventions significantly reduced the incidence of PUs (odds ratio: 0.24, 95% confidence intervals [CI]: 0.17–0.34, p < 0.001) and also significantly improved the levels of anxiety (standardized mean difference [SMD]: −1.39, 95% CI: −1.57 to 1.22, p < 0.001) and depression (SMD: −1.64, 95% CI: −2.02 to 1.26, p < 0.001) in ICU patients. This study indicates that the application of cluster nursing interventions in ICU patients can effectively reduce the incidence of PUs, as well as improve patients' anxiety and depression levels, thereby enhancing their quality of life, which is worth clinical promotion and application.
Chronic wounds are common in clinical practice, with long treatment cycle and high treatment cost. Changes in wound area can well predict the effectiveness of treatment and the possibility of healing. Therefore, continuous wound monitoring and evaluation are particularly important. Traditional manual wound measurement tends to overestimate wound area. Recently, various intelligent wound measurement devices have been introduced into clinical practice. This review aims to summarise the reliability, validity, types and measurement principles of different intelligent wound measurement devices, so as to analyse the clinical value and application prospect. Articles numbering 2610 were retrieved from the database, and 14 articles met the inclusion criteria. The results showed that the intelligent wound measurement devices included in the study reported good reliability and validity. Contact devices can lead to wound bed damage, wound deformation, patient pain, and is not convenient for electronic wound recording; partial contact devices can complete continuous monitoring and recording of wounds, but are not sensitive to wound depth measurement. Non-contact devices are more accurate in capturing wound images. In addition to wound measurement, they also have the function of wound assessment. In general, handheld and portable non-contact devices have great clinical value and promotion prospects.
Diabetic foot ulcers (DFUs) are a serious chronic complication of diabetes mellitus and a leading cause of disability and death in diabetic patients. However, current treatments remain unsatisfactory. Although macrophages are associated with DFU, their exact role in this disease remains uncertain. This study sought to detect macrophage-related genes in DFU and identify possible therapeutic targets. Single-cell datasets (GSE223964) and RNA-seq datasets (GSM68183, GSE80178, GSE134431 and GSE147890) associated with DFU were retrieved from the gene expression omnibus (GEO) database for this study. Analysis of the provided single-cell data revealed the distribution of macrophage subpopulations in the DFU. Four independent RNA-seq datasets were merged into a single DFU cohort and further analysed using bioinformatics. This included differential expression (DEG) analysis, multiple machine learning algorithms to identify biomarkers and enrichment analysis. Finally, key results were validated using reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and Western bolt. Finally, the findings were validated using RT-qPCR and western blot. We obtained 802 macrophage-related genes in single-cell analysis. Differential expression analysis yielded 743 DEGs. Thirty-seven macrophage-associated DEGs were identified by cross-analysis of marker genes with macrophage-associated DEGs. Thirty-seven intersections were screened and cross-analysed using four machine learning algorithms. Finally, HMOX1 was identified as a potentially valuable biomarker. HMOX1 was significantly associated with biological pathways such as the insulin signalling pathway. The results showed that HMOX1 was significantly overexpressed in DFU samples. In conclusion, the analytical results of this study identified HMOX1 as a potentially valuable biomarker associated with macrophages in DFU. The results of our analysis improve our understanding of the mechanism of macrophage action in this disease and may be useful in developing targeted therapies for DFU.
Complex fractures present significant challenges in orthopaedic surgery, particularly in terms of postoperative wound healing. Nutritional status plays a crucial role in the recovery process, with early nutritional support potentially influencing wound healing outcomes. This meta-analysis aimed to assess the impact of early nutritional interventions on postoperative wound healing and scar formation in patients with complex fractures. From an initial pool of 1742 articles, 7 studies were selected for analysis. The results revealed that preoperative nutritional support significantly improved early wound healing, as indicated by lower REEDA scores (SMD = −14.06, 95% CI: [−16.79, −11.32], p < 0.01) 1 week post-surgery. Furthermore, there was a notable reduction in scar formation, as demonstrated by lower Manchester Scar Scale scores (SMD = −25.03, 95% CI: [−30.32, −19.74], p < 0.01) 3 months post-surgery. These findings highlight the importance of incorporating nutritional strategies into the management of complex fractures to optimize postoperative recovery.
Following pancreatic resection, there may be a variety of complications, including wound infection, haemorrhage, and abdominal infection. The placement of drainage channels during operation may decrease the chances of postoperative complications. However, what kind of drainage can decrease the rate of postoperative complications is still a matter of debate. The purpose of this research is to evaluate the efficacy of both active and passive drainage for post-operation wound complications. From the beginning of the database until November 2023, EMBASE, the Cochrane Library and the Pubmed database have been searched. The two authors collected 2524 related studies from 3 data bases for importation into Endnote software, and 8 finished trials were screened against the exclusion criteria. Passive drainage can decrease the incidence of superficial wound infection in postoperative patients with pancreas operation (Odds Ratio [OR], 1.30; 95% CI, 1.06–1.60 p = 0.01); No statistically significant difference was found in the incidence of deep infections among the two groups (OR, 1.51; 95% CI, 0.68–3.36 p = 0.31); No statistical significance was found for the rate of haemorrhage after active drainage on the pancreas compared with that of passive drainage (OR, 0.72; 95% CI, 0.29–1.77 p = 0.47); No statistically significant difference was found in the rate of death after operation for patients who had received a pancreas operation in active or passive drainage (OR, 0.90; 95% CI, 0.57–1.42 p = 0.65); On the basis of existing evidence, the use of passive abdominal drainage reduces postoperative surface wound infections in patients. But there were no statistically significant differences in the risk of severe complications, haemorrhage after surgery, or mortality. However, because of the limited sample size of this meta-analysis, it is necessary to have more high-quality research with a large sample size to confirm the findings.
This study evaluated the effectiveness of a multi-disciplinary diabetic limb salvage programme in improving clinical outcomes and optimising healthcare utilisation in 406 patients aged ≥80 years with diabetic foot ulcers (DFUs), compared to 2392 younger patients enrolled from June 2020 to June 2021 and against 1716 historical controls using one-to-one propensity score matching. Results showed that elderly programme patients had lower odds of amputation-free survival (odds ratio: 0.64, 95% CI: 0.47, 0.88) and shorter cumulative length of stay (LOS) compared to younger programme patients (incidence rate ratio: 0.45, 95% CI: 0.29, 0.69). Compared to the matched controls, participating in the programme was associated with 5% higher probability of minor lower extremity amputation, reduced inpatient admissions and emergency visits, shorter LOS but increased specialist and primary care visits (all p-values <0.05). The findings suggest that the programme yielded favourable impacts on the clinical outcomes of patients aged≥80 years with DFUs. Further research is needed to develop specific interventions tailoring to the needs of the elderly population and to determine their effectiveness on patient outcomes while accounting for potential confounding factors.
An area of increasing interest continues to be the interaction between music therapy and its impacts on the autonomic nervous system (ANS) and wound repair in patients who have experienced trauma. This study intended to quantify the effect of music therapy on ANS regulation and wound healing. A cross-sectional observational study from March to December 2023 was undertaken involving 500 trauma patients. A control group received standard care, and an experimental group received daily 30-min music therapy sessions. Heart rate variability (HRV), cortisol levels, wound healing rates and patient-reported outcomes regarding pain, tension and well-being were among the critical parameters assessed. After 1 month, the experimental group exhibited a statistically significant rise in HRV (p < 0.05), suggesting increased parasympathetic activity. The experimental group exhibited a significant decrease in cortisol levels in comparison to the control group, with notable reduction observed after 1 month (p < 0.05). At 9 months, the experimental group exhibited significantly faster wound healing than the control group, with 85% wound recovery as opposed to 75% in control group. There was notable decrease in pain and stress scores at all time intervals in the music therapy group, with the greatest reduction occurring at the 9-month mark (p < 0.05). A significant positive correlation (p < 0.05) was identified between the number of completed music therapy sessions and patient outcomes, with individuals attending more than 20 sessions experiencing 33.6% positive outcomes. In trauma patients, music therapy substantially enhanced ANS regulation and accelerated wound healing. As evidenced by the elevated HRV and decreased cortisol levels, the therapy induced a physiologically tranquil state that is conducive to recovery. The considerable enhancements in the rates of wound healing, in conjunction with the substantial decreases in pain and tension levels, highlighted the therapeutic capacity of music therapy as intervention in trauma care. Additionally, the observed dose–response relationship indicated that customised music therapy regimens are crucial for achieving the best possible results for patients.
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.
