Exploring novel immunotherapy biomarker candidates induced by cancer deformation

by Se Min Kim, Namu Park, Hye Bin Park, JuKyung Lee, Changho Chun, Kyung Hoon Kim, Jong Seob Choi, Hyung Jin Kim, Sekyu Choi, Jung Hyun Lee

Triple-negative breast cancer (TNBC) demands urgent attention for the development of effective treatment strategies due to its aggressiveness and limited therapeutic options [1]. This research is primarily focused on identifying new biomarkers vital for immunotherapy, with the aim of developing tailored treatments specifically for TNBC, such as those targeting the PD-1/PD-L1 pathway. To achieve this, the study places a strong emphasis on investigating Ig genes, a characteristic of immune checkpoint inhibitors, particularly genes expressing Ig-like domains with altered expression levels induced by "cancer deformation," a condition associated with cancer malignancy. Human cells can express approximately 800 Ig family genes, yet only a few Ig genes, including PD-1 and PD-L1, have been developed into immunotherapy drugs thus far. Therefore, we investigated the Ig genes that were either upregulated or downregulated by the artificial metastatic environment in TNBC cell line. As a result, we confirmed the upregulation of approximately 13 Ig genes and validated them using qPCR. In summary, our study proposes an approach for identifying new biomarkers applicable to future immunotherapies aimed at addressing challenging cases of TNBC where conventional treatments fall short.

Introduction

More than 170 countries have implemented disability-targeted social protection programmes, although few have been rigorously evaluated. Consequently, a non-randomised controlled trial is being conducted of a pilot ‘cash-plus’ programme implemented by UNICEF Laos and the Laos government for children with disabilities in the Xiengkhouang Province in Laos. The intervention combines a regular cash transfer with provision of assistive devices and access for caregivers to a family support programme.

Methods and analysis

The non-randomised controlled trial will involve 350 children with disabilities across 3 districts identified by programme implementers as eligible for the programme (intervention arm). Implementers have also identified approximately 180 children with disabilities in neighbouring districts, who would otherwise meet eligibility criteria but do not live in the project areas (control arm). The trial will assess the impact of the programme on child well-being (primary outcome), as well as household poverty, caregiver quality of life and time use (secondary outcomes). Baseline data are being collected May–October 2023, with endline 24 months later. Analysis will be intention to treat. A complementary process evaluation will explore the implementation, acceptability of the programme, challenges and enablers to its delivery and mechanisms of impact.

Ethics and dissemination

The study has received ethical approval from the London School of Hygiene and Tropical Medicine and the National Ethics Committee for Health Research in Laos. Informed consent and assent will be taken by trained data collectors. Data will be collected and stored on a secure, encrypted server and its use will follow a detailed data management plan. Findings will be disseminated in academic journals and in short briefs for policy and programmatic actors, and in online and in-person events.

Combining antibiotic‐loaded bone cement‐based free vastus lateralis muscle‐sparing flap with split‐thickness skin grafts: A reliable strategy for reconstructing diabetic foot ulcers at non‐weight‐bearing areas

Abstract

Diabetic foot ulcers (DFUs) present significant challenges due to their associated amputation rates, mortality, treatment complexity and excessive costs. Our earlier work introduced a wound surgical integrated treatment (WSIT) for DFUs, yielding promising outcomes. This study focuses on a specific WSIT protocol employing antibiotic-loaded bone cement (ALBC) in the first Stage, and free vastus lateralis muscle-sparing (VLMS) flaps and split-thickness skin grafts (STSGs) in the second stage to repair non-weight-bearing DFUs. From July 2021 to July 2023, seven DFU patients (aged 47–71 years) underwent this treatment. Demographic data, hospital stay and repair surgery times were collected. Histological and immunohistochemical analyses assessed angiogenesis, collagen deposition and inflammation. SF-36 questionnaire measured pre- and postoperative quality of life. Preoperative ultrasound Doppler showed that the peak blood flow velocity of the recipient area artery was significantly >30 cm/s (38.6 ± 6.8 cm/s) in all patients. Muscle flap sizes varied from 8 × 3.5 × 1 to 18 × 6 × 2 cm. The operation time of the repair surgery was 156.9 ± 15.08 minutes, and the hospital stay was 18.9 ± 3.3 days. Histological analysis proved that covering DFUs with ALBC induced membrane formation and increased collagen, neovascularization and M2 macrophages fraction while reducing M1 macrophages one. All grafts survived without amputation during a 7- to 24-month follow-up, during which SF-36 scores significantly improved. A combination of ALBC with free VLMS flaps and STSGs proved to be safe and effective for reconstructing non-weight-bearing DFUs. It rapidly controlled infection, enhanced life quality and foot function, and reduced hospitalization time. We advocate integrating this strategy into DFU treatment plans.

Analysis of the associated factors in postoperative wound infection following open reduction and internal fixation for elbow fracture

Abstract

Postoperative wound infections (PWIs) following open reduction and internal fixation (ORIF) for elbow fractures can significantly affect patient outcomes. Identifying associated risk factors is crucial for improving clinical practices and patient care. A retrospective analysis (June 2020–June 2023) at our institution involved 90 patients who underwent elbow ORIF. Thirty patients developed PWIs (case group), compared to 60 who did not (control group). Variables like anaemia, operation duration, hospital stay, blood loss, body mass index (BMI), age, hypoalbuminemia, smoking status, diabetes mellitus and open fractures were examined. Univariate and multivariate analyses determined the impact of these variables on PWI incidence, with statistical significance set at p < 0.05. The main pathogens identified were Escherichia coli among Gram-negative bacteria (59.46%) and Staphylococcus aureus among Gram-positive bacteria (40.54%). In the univariate analysis, hypoalbuminemia, anaemia, and lifestyle factors such as smoking showed higher prevalence in patients with PWIs. However, age and length of hospital stay did not significantly influence infection rates. The multivariate analysis further elucidated that anaemia, smoking, diabetes mellitus and open fractures were independent, significant predictors of PWIs. These findings highlight the complexity of factors influencing infection risk post-ORIF, underscoring the importance of both individual health conditions and surgical complications in patient outcomes. Anaemia, smoking, diabetes mellitus and open fractures significantly increase the risk of PWI after elbow ORIF. Early identification and management of these risk factors are imperative to reduce infection rates and improve postoperative recovery.

Objectives

To estimate all-cause mortality in ventilator-associated pneumonia (VAP) and determine whether antibiotic duration beyond 8 days is associated with reduction in all-cause mortality in patients admitted with VAP in the intensive care unit.

Design

A prospective cohort study of patients diagnosed with VAP based on the National Healthcare Safety Network definition and clinical criteria.

Setting

Single tertiary care hospital in Southern India.

Participants

100 consecutive adult patients diagnosed with VAP were followed up for 28 days postdiagnosis or until discharge.

Outcome measures

The incidence of mortality at 28 days postdiagnosis was measured. Tests for association and predictors of mortality were determined using 2 test and multivariate Cox regression analysis. Secondary outcomes included baseline clinical parameters such as age, underlying comorbidities as well as measuring total length of stay, number of ventilator-free days and antibiotic-free days.

Results

The overall case fatality rate due to VAP was 46%. There was no statistically significant difference in mortality rates between those receiving shorter antibiotic duration (5–8 days) and those on longer therapy. Among those who survived until day 9, the observed risk difference was 15.1% between both groups, with an HR of 1.057 (95% CI 0.26 to 4.28). In 70.4% of isolates, non-fermenting Gram-negative bacilli were identified, of which the most common pathogen isolated was Acinetobacter baumannii (62%).

Conclusion

In this hospital-based cohort study, there is insufficient evidence to suggest that prolonging antibiotic duration beyond 8 days in patients with VAP improves survival.

Identifying a group of factors predicting cognitive impairment among older adults

by Longgang Zhao, Yuan Wang, Eric Mishio Bawa, Zichun Meng, Jingkai Wei, Sarah Newman-Norlund, Tushar Trivedi, Hatice Hasturk, Roger D. Newman-Norlund, Julius Fridriksson, Anwar T. Merchant

Background

Cognitive impairment has multiple risk factors spanning several domains, but few studies have evaluated risk factor clusters. We aimed to identify naturally occurring clusters of risk factors of poor cognition among middle-aged and older adults and evaluate associations between measures of cognition and these risk factor clusters.

Methods

We used data from the National Health and Nutrition Examination Survey (NHANES) III (training dataset, n = 4074) and the NHANES 2011–2014 (validation dataset, n = 2510). Risk factors were selected based on the literature. We used both traditional logistic models and support vector machine methods to construct a composite score of risk factor clusters. We evaluated associations between the risk score and cognitive performance using the logistic model by estimating odds ratios (OR) and 95% confidence intervals (CI).

Results

Using the training dataset, we developed a composite risk score that predicted undiagnosed cognitive decline based on ten selected predictive risk factors including age, waist circumference, healthy eating index, race, education, income, physical activity, diabetes, hypercholesterolemia, and annual visit to dentist. The risk score was significantly associated with poor cognitive performance both in the training dataset (OR Tertile 3 verse tertile 1 = 8.15, 95% CI: 5.36–12.4) and validation dataset (OR Tertile 3 verse tertile 1 = 4.31, 95% CI: 2.62–7.08). The area under the receiver operating characteristics curve for the predictive model was 0.74 and 0.77 for crude model and model adjusted for age, sex, and race.

Conclusion

The model based on selected risk factors may be used to identify high risk individuals with cognitive impairment.

Predictive value of CD86 for the occurrence of sepsis (Sepsis-3) in patients with infection

by Dan lv, Keji Zhang, Changqing Zhu, Xinhui Xu, Hao Gong, Li Liu

This prospective observational study explored the predictive value of CD86 in the early diagnosis of sepsis in the emergency department. The primary endpoint was the factors associated with a diagnosis of sepsis. The secondary endpoint was the factors associated with mortality among patients with sepsis. It enrolled inpatients with infection or high clinical suspicion of infection in the emergency department of a tertiary Hospital between September 2019 and June 2021. The patients were divided into the sepsis and non-sepsis groups according to the Sepsis-3 standard. The non-sepsis group included 56 patients, and the sepsis group included 65 patients (19 of whom ultimately died). The multivariable analysis showed that CD86% (odds ratio [OR] = 1.22, 95% confidence interval [CI]: 1.04–1.44, P = 0.015), platelet count (OR = 0.99, 95%CI: 0.986–0.997, P = 0.001), interleukin-10 (OR = 1.01, 95%CI: 1.004–1.025, P = 0.009), and procalcitonin (OR = 1.17, 95%CI: 1.01–1.37, P = 0.043) were independent risk factors for sepsis, while human leukocyte antigen (HLA%) (OR = 0.96, 05%CI: 0.935–0.995, P = 0.022), respiratory rate (OR = 1.16, 95%CI: 1.03–1.30, P = 0.014), and platelet count (OR = 1.01, 95%CI: 1.002–1.016, P = 0.016) were independent risk factors for death in patients with sepsis. The model for sepsis (CD86%, platelets, interleukin-10, and procalcitonin) and the model for death (HLA%, respiratory rate, and platelets) had an area under the curve (AUC) of 0.870 and 0.843, respectively. CD86% in the first 24 h after admission for acute infection was independently associated with the occurrence of sepsis in the emergency department.

Comparative analysis of pressure ulcer development in stroke patients within and outside healthcare facilities: A systematic review and meta‐analysis

Abstract

The risk of pressure ulcers in stroke patients is a significant concern, impacting their recovery and quality of life. This systematic review and meta-analysis investigate the prevalence and risk factors of pressure ulcers in stroke patients, comparing those in healthcare facilities with those in home-based or non-clinical environments. The study aims to elucidate how different care settings affect the development of pressure ulcers, serving as a crucial indicator of patient care quality and management across diverse healthcare contexts. Following PRISMA guidelines, a comprehensive search was conducted across PubMed, Embase, Web of Science and the Cochrane Library. Inclusion criteria encompassed studies on stroke patients in various settings, reporting on the incidence or prevalence of pressure ulcers. Exclusion criteria included non-stroke patients, non-original research and studies with incomplete data. The Newcastle–Ottawa scale was used for quality assessment, and statistical analyses involved both fixed-effect and random-effects models, depending on the heterogeneity observed. A total of 1542 articles were initially identified, with 11 studies meeting the inclusion criteria. The studies exhibited significant heterogeneity, necessitating the use of a random-effects model. The pooled prevalence of pressure injuries was 9.53% in patients without family medical services and 2.64% in patients with medical services. Sensitivity analysis confirmed the stability of these results, and no significant publication bias was detected through funnel plot analysis and Egger's linear regression test. The meta-analysis underscores the heightened risk of pressure injuries in stroke patients, especially post-discharge. It calls for concerted efforts among healthcare providers, policymakers and caregivers to implement targeted strategies tailored to the specific needs of different care environments. Future research should focus on developing and evaluating interventions to effectively integrate into routine care and reduce the incidence of pressure injuries in stroke patients.

Effect of two different peritoneal dialysis modalities on wound infection in peritoneal dialysis patients: A meta‐analysis

Abstract

Peritoneal dialysis(PD) is one of the most efficient methods in end-stage kidney disease, and it is very important for PD to perform well. No research has been conducted to evaluate the effect of various types of PD catheters on the prognosis of post-operative wound complications. While recent meta-analyses are in favour of straight tubing, there is still uncertainty as to whether direct or coiled PD is beneficial. The purpose of this meta-analysis was to compare the efficacy of direct and coiled PD catheters on the incidence of post-operative wound infection, bleeding and peritonitis. A comprehensive search was carried out on three databases, including PubMed and Embase, and a manual search was carried out on the links in the paper. The results showed that the incidence rate of bleeding after operation and the degree of infection among the straight and coiled pipes were compared. The results showed that there were no statistically significant differences in the incidence of post-operative wound infection among straight PD patients with coiled PD (OR, 0.79; 95% CI, 0.58–1.08 p = 0.13). No statistical significance was found in the case of PD with coiled tubing compared with that of straight PD group in wound leakage (OR, 1.17; 95% CI, 0.71–1.93 p = 0.55). No statistically significantly different rates of post-operative peritonitis were observed for coiled tubing compared with straight ones in PD patients (OR, 1.06; 95% CI, 0.78–1.45 p = 0.7). There is no statistical significance on the rate of wound infection, wound leakage and peritonitis among coiled and straight tube in PD.

Inter-reviewer reliability of human literature reviewing and implications for the introduction of machine-assisted systematic reviews: a mixed-methods review

Por: Hanegraaf · P. · Wondimu · A. · Mosselman · J. J. · de Jong · R. · Abogunrin · S. · Queiros · L. · Lane · M. · Postma · M. J. · Boersma · C. · van der Schans · J.
Objectives

Our main objective is to assess the inter-reviewer reliability (IRR) reported in published systematic literature reviews (SLRs). Our secondary objective is to determine the expected IRR by authors of SLRs for both human and machine-assisted reviews.

Methods

We performed a review of SLRs of randomised controlled trials using the PubMed and Embase databases. Data were extracted on IRR by means of Cohen’s kappa score of abstract/title screening, full-text screening and data extraction in combination with review team size, items screened and the quality of the review was assessed with the A MeaSurement Tool to Assess systematic Reviews 2. In addition, we performed a survey of authors of SLRs on their expectations of machine learning automation and human performed IRR in SLRs.

Results

After removal of duplicates, 836 articles were screened for abstract, and 413 were screened full text. In total, 45 eligible articles were included. The average Cohen’s kappa score reported was 0.82 (SD=0.11, n=12) for abstract screening, 0.77 (SD=0.18, n=14) for full-text screening, 0.86 (SD=0.07, n=15) for the whole screening process and 0.88 (SD=0.08, n=16) for data extraction. No association was observed between the IRR reported and review team size, items screened and quality of the SLR. The survey (n=37) showed overlapping expected Cohen’s kappa values ranging between approximately 0.6–0.9 for either human or machine learning-assisted SLRs. No trend was observed between reviewer experience and expected IRR. Authors expect a higher-than-average IRR for machine learning-assisted SLR compared with human based SLR in both screening and data extraction.

Conclusion

Currently, it is not common to report on IRR in the scientific literature for either human and machine learning-assisted SLRs. This mixed-methods review gives first guidance on the human IRR benchmark, which could be used as a minimal threshold for IRR in machine learning-assisted SLRs.

Effect of two different surgical modalities for pelvic organ prolapse on postoperative wound infection in patients: A meta‐analysis

Abstract

Sacrospinous ligament fixation (SSLF) is widely applied to the treatment of female pelvis organ prolapsed. Contradictory findings have already been reported in the comparison of sacrocolpopexy (SC) with SSLF. The objective of this study is to evaluate the efficacy of SC versus SSLF in treating pelvis organ prolapsed after operation. We conducted a meta-analysis of both operative approaches, including PubMed, Embase, and Cochrane Library. In this research, 822 articles were chosen from three databases, 201 were copied, and 10 were included. Among them, 7248 cases were operated on the prolapsed pelvis. It was found that SSLF surgery could significantly decrease the rate of postoperative wound infection after operation (odds ratio [OR], 0.59; 95% confidence interval [CI], 0.42–0.82; p = 0.001). No statistical significance was found among the SSLF and the SC surgery for the post-operation haemorrhage of the patient (OR, 0.81; 95% CI, 0.23–2.83; p = 0.75). No statistical significance was found among the SSLF and the SC surgery for the postoperative period of the patient's operation (mean difference, −15.46; 95% CI, −52.87 to 21.94; p = 0.42). Applying SSLF surgery to treat pelvic prolapse in women may benefit from a reduction in the number of post-operative wound infections. However, SSLF had no statistical significance with respect to the amount of haemorrhage after operation or operation time.

YouTube as a source of information for pressure injury: Quality assessment and content analysis

Abstract

We aimed to assess the quality and reliability of pressure injury-related videos uploaded on YouTube, analyse the sources and contents, and examine the correlation between video parameters. We searched YouTube using two keywords, “pressure ulcer” and “pressure sore”, on August 20, 2022. We sorted the videos according to their number of views and included the top 100 videos for each keyword. The quality of videos was assessed using the Global Quality Scale (GQS), while their reliability was evaluated by the modified DISCERN (mDISCERN) tool. In addition, we evaluated the videos in which content was included, analysed the correlations and differences between GQS, mDISCERN, and video parameters. We initially found a total of 100 videos for each keyword and finally included and analysed 77 videos. The mean scores for the mDISCERN and GQS were 2.35 ± 0.98 and 3.09 ± 0.99, respectively. Both GQS and mDISCERN showed statistically significant correlations with each other (rho = 0.54, p < 0.0001*) and with the length of the videos, respectively (rho = 0.36, p = 0.001*), (rho = 0.29, p = 0.01*). Of the videos created by physicians, 8 (57.1%) included content related to treatment, while of the videos created by nonphysician health personnel, 22 (57.9%) included content related to prevention. Analysing whether there were differences in video parameters based on the sources, we observed significant differences between sources in GQS (p < 0.0001*), mDISCERN (p < 0.0001*), and video length (p = 0.001*). In the post-hoc analysis, videos uploaded by physicians or nonphysician health personnel showed higher quality and reliability than videos uploaded by other sources. Therefore, the results of this study could be useful for healthcare providers, as well as patients and caregivers, to search for high-quality and reliable YouTube videos related to pressure injury.

Effect of Chinese herbal compound dressings in treating patients with diabetic foot ulcers: A meta‐analysis

Abstract

This meta-analysis aims to systematically investigate the clinical efficacy of Chinese herbal compound dressings in treating patients with diabetic foot ulcers (DFUs). A comprehensive computerised search was conducted in databases including PubMed, Embase, Google Scholar, Cochrane Library, China National Knowledge Infrastructure, and Wanfang databases, from database inception to November 2023, to identify randomised controlled trials (RCTs) concerning the use of Chinese herbal compound dressings in patients with DFU. Two researchers independently screened the literature, extracted data, and assessed the quality based on inclusion and exclusion criteria. Data analysis was performed using Stata 17.0 software. Overall, 18 RCTs involving 1405 DFU patients were included. The analysis indicated that compared to the control group, the group treated with Chinese herbal compound dressings had significantly shorter ulcer healing time (standardised mean difference [SMD] = −2.49, 95% confidence interval [CI]: −3.53 to −1.46, p < 0.001), reduced ulcer surface area (SMD = −3.38, 95% CI: −4.67 to −2.09, p < 0.001), and higher healing rates (odds ratio [OR] = 2.24, 95% CI: 1.72–2.92, p < 0.001) as well as overall effectiveness rates (OR = 4.56, 95% CI: 3.10–6.71, p < 0.001). This study demonstrates that the external application of Chinese herbal compound dressings in patients with DFU can significantly shorten the ulcer healing time and improve wound healing rates.

Multi‐disciplinary diabetic limb salvage programme in octogenarians with diabetic foot ulcers is not futile: An observational study with historical controls

Abstract

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.

Risk assessment and pathogen profile of surgical site infections in traumatic brain injury patients undergoing emergency craniotomy: A retrospective study

Abstract

Emergency craniotomy in patients with traumatic brain injury poses a significant risk for surgical site infections (SSIs). Understanding the risk factors and pathogenic characteristics of SSIs in this context is crucial for improving outcomes. This comprehensive retrospective analysis spanned from February 2020 to February 2023 at our institution. We included 25 patients with SSIs post-emergency craniotomy and a control group of 50 patients without SSIs. Data on various potential risk factors were collected, including demographic information, preoperative conditions, and intraoperative details. The BACT/ALERT3D Automated Bacterial Culture and Detection System was utilized for rapid bacterial pathogen identification. Statistical analyses included univariate and multivariate logistic regression to identify significant risk factors for SSIs. The study identified Klebsiella pneumoniae, Escherichia coli, and Staphylococcus aureus as the most prevalent pathogens in SSIs. Significant risk factors for SSIs included the lack of preoperative antibiotic use, postoperative drainage tube placement, diabetes mellitus, and the incorporation of invasive procedures, all of which showed a significant association with SSIs in the univariate analysis. The multivariate analysis further highlighted the protective effect of preoperative antibiotics and the increased risks associated with anaemia, diabetes mellitus, postoperative drainage tube placement, and the incorporation of invasive procedures. Our research underscores the critical role of factors like insufficient preoperative antibiotics, postoperative drainage, invasive techniques, anaemia, and diabetes mellitus in elevating the risk of surgical site infections in traumatic brain injury patients undergoing emergency craniotomy. Enhanced focus on these areas is essential for improving surgical outcomes.

Introduction

Community-based participatory research (CBPR) is a collaborative research approach that equally engages researchers and community stakeholders throughout all steps of the research process to facilitate social change and increase research relevance. Community advisory boards (CABs) are a CBPR tool in which individuals with lived experience and community organisations are integrated into the research process and ensure the work aligns with community priorities. We seek to (1) explore the best practices for the recruitment and engagement of people with lived experiences on CABs and (2) identify the scope of literature on minimising power dynamics between organisations and community members with lived experience who work on CABs together.

Methods and analysis

This scoping review will follow the Arksey and O’Malley methodological framework, informed by Levac et al, and will be reported using a PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) diagram. Detailed and robust search strategies have been developed for Embase, Medline and PsychINFO. Grey literature references and reference lists of included articles published between 1 January 1990 and 30 March 2023 will be considered. Two reviewers will independently screen references in two successive stages of title/abstract and full-text screening. Conflicts will be decided by consensus or a third reviewer. Thematic analysis will be applied in three phases: open coding, axial coding and abstraction. Extracted data will be recorded and presented in a tabular format and/or graphical summaries, with a descriptive overview discussing how the research findings relate to the research questions. At this time, a preliminary search of peer-reviewed and grey literature has been conducted. Search results for peer-reviewed literature have been uploaded to Covidence for review and appraisal for relevance.

Ethics and dissemination

Formal ethics approval is not required for this review. Review findings will inform ongoing and future CBPR community advisory board dynamics.

Introduction

Pre-eclampsia affects ~5%–7% of pregnancies. Although improved obstetric care has significantly diminished its associated maternal mortality, it remains a leading cause of maternal morbidity and mortality in the world. Term pre-eclampsia accounts for 70% of all cases and a large proportion of maternal–fetal morbidity related to this condition. Unlike in preterm pre-eclampsia, the prediction and prevention of term pre-eclampsia remain unsolved. Previously proposed approaches are based on combined third-trimester screening and/or prophylactic drugs, but these policies are unlikely to be widely implementable in many world settings. Recent evidence shows that the soluble fms-like tyrosine kinase-1 (s-Flt-1) to placental growth factor (PlGF) ratio measured at 35–37 weeks’ gestation predicts term pre-eclampsia with an 80% detection rate. Likewise, recent studies demonstrate that induction of labour beyond 37 weeks is safe and well accepted by women. We hypothesise that a single-step universal screening for term pre-eclampsia based on sFlt1/PlGF ratio at 35–37 weeks followed by planned delivery beyond 37 weeks reduces the prevalence of term pre-eclampsia without increasing the caesarean section rates or worsening the neonatal outcomes.

Methods and analysis

We propose an open-label randomised clinical trial to evaluate the impact of a screening of term pre-eclampsia with the sFlt-1/PlGF ratio followed by planned delivery in asymptomatic nulliparous women at 35–37 weeks. Women will be assigned 1:1 to revealed (sFlt-1/PlGF known to clinicians) versus concealed (unknown) arms. A cut-off of >90th centile is used to define the high risk of subsequent pre-eclampsia and offer planned delivery from 37 weeks. The efficacy variables will be analysed and compared between groups primarily following an intention-to-treat approach, by ORs and their 95% CI. This value will be computed using a Generalised Linear Mixed Model for binary response (study group as fixed effect and the centre as intercept random effect).

Ethics and dissemination

The study is conducted under the principles of Good Clinical Practice. This study was accepted by the Clinical Research Ethics Committee of Hospital Clinic Barcelona on 20 November 2020. Subsequent approval by individual ethical committees and competent authorities was granted. The study results will be published in peer-reviewed journals and disseminated at international conferences.

This project used a scoping review methodology created and developed by Peters and colleagues and the Joanna Briggs Institute. The review searched academic databases and screened existing studies that met predetermined inclusion criteria.

Data sources

Seven academic databases and Google Scholar were searched with sets of search terms.

Eligibility

The included studies examined participants who were final-year university students or those who had graduated from university within a 3-year period. Studies published in English since 2000 and from any country were included. The review included studies examining the negative dimensions of mental health. The review excluded studies focusing on medical students and graduates.

Data extraction

Basic information about the studies and their findings on mental health and university-to-work transitions was retrieved. The findings are presented in tables and in a qualitative thematic summary.

Results

The scoping review included 12 studies. Mental health was often not explicitly defined and it’s theoretical foundations were not clearly articulated. The review identified factors, including a lack of social support and economic precarity, as sources of adverse mental health. Other protective factors in these studies—variables that guard against mental health problems—were identified, such as career preparedness and having a good job.

Conclusions

Despite the methodological focus on the negative aspects of mental health, people’s mental health experiences during university-to-work transitions are not uniformly negative. Clear conceptualisations of mental health in future studies will aid in developing resources to improve well-being.

Trial registration number

This scoping review adhered to a protocol previously published in this journal and that is registered on the Open Science Framework website (https://osf.io/gw86x).

Factors affecting the efficiency of equine embryo transfer (EET) in polo mares under subtropical conditions of Pakistan

by Khalid Mahmood, Aijaz Ali Channa, Aamir Ghafoor, Amjad Riaz

Equine embryo transfer (EET) is a prominent technology in the equine breeding industry, and its efficacy is affected by a number of factors. The current study aimed to determine the effects of the breed of donor/recipient mares, estrus/ovulation induction treatment, cooled transportation of embryos, and synchrony between donor and recipient mares on the efficiency of the EET under subtropical conditions of Pakistan. A total of eighty-four (n = 84) Polo-playing donor mares (Argentino-polo = 41 and Anglo-Arab = 43) and seventy (n = 70) recipient mares (light breed = 26 and heavy breed = 44) were used for EET. The donor mares exhibiting natural estrus (n = 28) were detected by teaser a stallion, and corpus luteum (CL) having mares (n = 56) were treated with prostaglandin (150 μg of Cloprostenol) for estrus induction. The mares’ follicular growth was monitored through ultrasonography until the dominant follicle’s size reached 35 mm or more with a moderate to obvious uterine edema score. Afterward, the mares were treated either with GnRH, i.e., 50 μg of Lecirelin acetate (n = 41) or Ovusyn, i.e., 1500 IU hCG (n = 43). Insemination with chilled semen was performed 24 hours later. The embryos were collected non-surgically, 7 or 8 days after ovulation, from the donor mares. The collected embryos were transferred into the well-synchronized recipient mares as fresh (n = 44) or chilled (n = 26) embryos. The pregnancy after ET was checked through ultrasonography. Statistical analysis revealed that the embryo recovery rate (ERR) remained significantly higher (P0.05) affect the ERR. There was no significant effect of the type (fresh vs chilled), classification, and stage of development of embryo on pregnancy outcomes (P>0.05). ET pregnancy rate was significantly affected by the breed of recipient mares and ovulation synchrony between donor and recipient mares (P

Knowledge and attitude towards stroke among the population of one rural community in southern Thailand: a survey

Por: Wanichanon · W. · Ananchaisarp · T. · Buathong · N. · Choomalee · K.
Objective

To evaluate attitude and knowledge of stroke in a rural community in southern Thailand.

Design

A survey.

Setting

A community in southern Thailand.

Participants

All community members aged ≥18 years who were at home during the survey were invited to participate.

Primary and secondary outcome measures

Level of attitude and knowledge score towards stroke were assessed, and the associated factors were evaluated.

Methods

The questionnaire used in this survey was developed from a literature review, and the content validity and reliability were tested before use. Logistic and linear regression were used to determine factors associated with the level of attitude and knowledge score towards stroke.

Results

Among 247 participants, most were Muslim and the median age was 54.0 years. The median (Q1, Q3) score of stroke risk factors was 5 (2, 7) (full score: 9). Participants who knew about stroke, had an acquaintance diagnosed with stroke and had a high level of attitude had significantly higher scores. Two-thirds of the participants had a low-to-moderate level of attitude. Furthermore, most high-risk participants (99/113) had a low to no chance awareness of their risk to stroke. The median (Q1, Q3) score of stroke warning symptoms was 6 (3, 7) (full score: 10). The participants who had received education via the Face Arm Speech Time (FAST) campaign demonstrated a significantly higher proportion of correct answers to the symptoms mentioned in the FAST.

Conclusion

About half of the participants in this community did not know some of the risk factors and warning symptoms of stroke. Moreover, most participants had a low-to-moderate level of attitude and underestimated their risk to stroke even in the high cardiovascular risk participants. The FAST may help people memorise the typical warning symptoms of stroke.
