Authors: Kyei-Gyamfi Sylvester , Kyei-Arthur Frank 
Published: July 2024

Abstract
Background
Loneliness affects individuals of all age groups, and mobile fishers are susceptible to loneliness due to the nature of their occupation. However, there is no study examining loneliness and risky behaviours among fishers in Ghana. Therefore, the purpose of this study was to examine fishers’ mobility history, prevalence of loneliness, predictors of loneliness, effects of loneliness on fishers, coping strategies to address loneliness, and prevalence of risky behaviour among fishers in Elmina, Ghana.

Methods
This is a convergent parallel mixed-method study involving 385 fishers in Elmina. A questionnaire and interview guides were used to collect data from respondents. Descriptive statistics, Pearson’s chi-square and Fisher exact tests, and binary logistic regression were used to analyse the quantitative data, while the qualitative data were analysed thematically.

Results
From the quantitative findings, most fishers were mobile (54.5%) and travelled alone (45.7%). Approximately 83% of the fishers experienced loneliness. Male fishers (AOR = 0.049; 95% CI = 0.003–0.741; p-value = 0.030), fishers affiliated with the African Traditionalist religion (AOR = 0.043; 95% CI = 0.002–0.846; p-value = 0.038), and fishers who travelled with their working colleagues (AOR = 0.002; 95% CI = 0.000-0.023; p-value = ≤ 0.001), were less likely to be experience loneliness. Feeling bored, isolated and worried/anxious were the main perceived effects of loneliness. Alcohol consumption and finding a companion to spend time with were the main strategies fishers used to cope with their loneliness. Most male fishers consumed alcohol (92.5%; p-value = ≤ 0.001) and spent time with companions (73.5%; p-value = ≤ 0.001) to cope with their loneliness. The quantitative and qualitative findings showed that fishers engaged in risky behaviours (excessive alcohol consumption, casual sex, and smoking marijuana and tobacco). From the quantitative findings, more male fishers engaged in excessive alcohol consumption (97.6% vs. 74.5%; p-value = ≤ 0.001), casual sex (88.2% vs. 61.7%, p-value = ≤ 0.001), smoking marijuana (43.0% vs. 13.0%, p-value = ≤ 0.001) and tobacco (49.4% vs. 19.1%; p-value = 0.001) than female fishers.

Conclusions
Loneliness and risky behaviours were common among fishers. Therefore, there is an urgent need to design interventions to help reduce loneliness and risky behaviour among fishers.

Abstract
Background
Faculty development programs are crucial for promoting continuous learning, enhancing teaching effectiveness, and encouraging professional growth among medical educators. Problem-based learning was introduced as a teaching strategy in our Faculty of Medicine in 2007. Thereafter, several rounds of a faculty development program were conducted to help teachers recognize their role as facilitators and assess areas for improvement.

Methods
We conducted a mixed-methods study with a sample of 284 third-year medical students answering a questionnaire and 21 faculty members participating in focus groups. A validated 13-item questionnaire was used to investigate the students’ evaluation of their tutors’ performance in problem-based learning. Three sessions were then conducted with faculty members involved in problem-based learning to gain in-depth insights into their experiences and perspectives.

Results
The mean performance ranking for tutors awarded by the students was above halfway. There was a significant positive correlation between tutors’ performance ranking and all five of the learning approaches examined herein: constructive/active learning, self-directed learning, contextual learning, collaborative learning, and intra-personal behavior (p < 0.05). The data from the focus groups were analyzed under five broad themes: tutors’ insights into their strengths and weaknesses, challenges in conducting problem-based learning, tutors’ ways of preparing for problem-based learning, feedback, and suggestions for improving problem-based learning workshops.

Conclusions
This study recommends improvements and future directions for advanced program evaluation. Faculty development programs can be tailored to effectively address students and faculty members’ goals and needs, which can benefit the teaching and learning process and foster a culture of continuous improvement and professional growth.

Abstract
Background
The atherogenic index of plasma (AIP) is closely associated with the onset of diabetes, with obesity being a significant risk factor for type 2 diabetes mellitus (T2DM). However, the association between the AIP and T2DM in overweight and obese populations has been infrequently studied. Therefore, this study aimed to explore this association in overweight and obese individuals with T2DM.

Methods
This cross-sectional analysis utilized data from 40,633 participants with a body mass index (BMI) ≥ 24 kg/m2 who were screened from January 2018 to December 2023 at Henan Provincial People’s Hospital. Participants were categorized into groups of overweight and obese individuals with and without diabetes according to the T2DM criteria. The AIP, our dependent variable, was calculated using the formula log10 [(TG mol/L)/HDL-C (mol/L)]. We investigated the association between the AIP and T2DM in overweight and obese individuals using multivariate logistic regression, subgroup analysis, generalized additive models, smoothed curve fitting, and threshold effect analysis. Additionally, mediation analysis evaluated the role of inflammatory cells in AIP-related T2DM.

Results
Overweight and obese patients with T2DM exhibited higher AIP levels than those without diabetes. After adjusting for confounders, our results indicated a significant association between the AIP and the risk of T2DM in overweight and obese individuals (odds ratio (OR) = 5.17, 95% confidence interval (CI) 4.69–5.69). Notably, participants with a high baseline AIP (Q4 group) had a significantly greater risk of T2DM than those in the Q1 group, with an OR of 3.18 (95% CI 2.94–3.45). Subgroup analysis revealed that the association between the AIP and T2DM decreased with increasing age (interaction P < 0.001). In overweight and obese populations, the association between AIP and T2DM risk displayed a J-shaped nonlinear pattern, with AIP > – 0.07 indicating a significant increase in T2DM risk. Various inflammatory cells, including neutrophils, leukocytes, and monocytes, mediated 4.66%, 4.16%, and 1.93% of the associations, respectively.

Conclusion
In overweight and obese individuals, the AIP was independently associated with T2DM, exhibiting a nonlinear association. Additionally, the association between the AIP and T2DM decreased with advancing age. Multiple types of inflammatory cells mediate this association.
Serum lipid metabolism characteristics and potential biomarkers in patients with unilateral sudden sensorineural hearing loss
Authors: Chen Xiaoyan , Zheng Zhong , Xie Daoyu , Xia Liang , Chen Yi , Dong Hongjun , Feng Yanmei 
Published: July 2024

Abstract
Background
Glycerophospholipids (GPLs) are essential for cell membrane structure and function. Sphingomyelin and its metabolites regulate cell growth, apoptosis, and stress responses. This study aimed to investigate lipid metabolism in patients experiencing sudden sensorineural hearing loss across all frequencies (AF-SSNHL).

Methods
The study included 60 patients diagnosed with unilateral AF-SSNHL, among whom 30 patients had a level of hearing improvement ≥ 15 dB after 6 months of follow-up. A propensity score-matched (2:1) control group was used. Liquid chromatography‒mass spectrometry based untargeted lipidomics analysis combined with multivariate statistics was performed to investigate the lipids change. The “lipidome” R package and weighted gene co-expression network analysis (WGCNA) were utilised to assess the lipids’ structural features and the association between lipids and hearing.

Results
Lipidomics successfully differentiated the AF-SSNHL group from the control group, identifying 17 risk factors, mainly including phosphatidylcholine (PC), phosphatidylethanolamine (PE), and related metabolites. The ratios of lysophosphatidylcholine/PC, lysophosphatidylethanolamine/PE, and lysodimethylphosphatidylethanolamine/PE were upregulated, while some glycerophospholipid (GPL)-plasmalogens were downregulated in the AF-SSNHL group, indicating abnormal metabolism of GPLs. Trihexosylceramide (d34:1), PE (18:1e_22:5), and sphingomyelin (d40:3) were significantly different between responders and nonresponders, and positively correlated with hearing improvement. Additionally, the results of the WGCNA also suggested that partial GPL-plasmalogens were positively associated with hearing improvement.

Conclusion
AF-SSNHL patients exhibited abnormally high blood lipids and pronounced GPLs metabolic abnormalities. Sphingolipids and GPL-plasmalogens had an association with the level of hearing improvement. By understanding the lipid changes, clinicians may be able to predict the prognosis of hearing recovery and personalize treatment approaches.

Published: July 2024

Abstract
Objective
To identify recurrent venous thromboembolism (VTE) after discontinuation of anticoagulation in patients with isolated distal deep vein thrombosis based on its anatomic localization (axial or muscular veins).

Methods
Data were sourced from PubMed, Embase, Cochrane Library, Web of Science, and ClinicalTrials.gov databases in the time period up to October 2023. The study followed PRISMA guidelines using a registered protocol (CRD42023443029). Studies reporting recurrent VTE in patients with axial or muscular DVT were included in the analysis.

Results
Five studies with a total of 1,403 participants were evaluated. The results showed a pooled odds ratio of 1.12 (95% confidence interval 0.77–1.63) between axial and muscular DVT. Heterogeneity was low (I2 = 0%, p = 0.91) and there was no significant difference in the rate of recurrent VTE between axial and muscular DVT in each subgroup.

Conclusions
Muscular and axial DVT showed comparable recurrent VTE rates after anticoagulation. However, uncertainties regarding the possibility of recurrence affecting the popliteal vein or resulting in pulmonary embolism following muscular DVT anticoagulation persisted. Randomized trials in patients with isolated distal DVT are still needed to clarify its prognosis for different anatomical thrombus locations.

Published: July 2024

Abstract
Background
It remains unclear whether the use of an orthopaedic traction table (TT) in direct anterior approach (DAA) total hip arthroplasty (THA) results in better outcomes. The aim of this systematic review and network meta-analysis was to compare the THA outcomes through DAA on a standard operating table and the THA outcomes through DAA on a TT.

Methods
PubMed, Epistemonikos, and Google Scholar were searched for relevant randomized controlled trials (RCTs) up to 01 January 2024. An indirect comparison in network meta-analysis was performed to assess treatment effects between DAA on a TT and DAA on a standard table, using fixed-effects and random-effects models estimated with frequentist approach and consistency assumption. Standardized mean differences (SMDs) with 95% confidence intervals (CIs) were estimated for continuous variables and odds ratios (ORs) with 95% CIs were estimated for binary variables.

Results
The systematic review of the literature identified 43 RCTs with a total of 2,258 patients. DAA with TT had a 102.3 mL higher intraoperative blood loss and a 0.6 mmol/L lower Hb 3 days postoperatively compared with DAA without TT (SMD = 102.33, 95% CI 47.62 to 157.04; SMD = − 0.60, 95% CI  − 1.19 to − 0.00). DAA with TT had a 0.15 lower periprosthetic fracture OR compared with DAA without TT (OR 0.15, 95% CI 0.03 to 0.86). There were no further significant differences in surgical, radiological, functional outcomes and in complication rates.

Conclusion
Based on our findings and taking into account the limitations, we recommend that particular attention be paid to the risk of periprosthetic fracture in DAA on a standard operating table and blood loss in DAA with TT. Since numerous other surgical, radiological, functional outcome parameters and other complication rates studied showed no significant difference between DAA on a standard operating table and DAA with TT, no recommendation for a change in surgical technique seems justified.

Level of evidence
Level I evidence, because this is a systematic review and meta-analysis of randomized controlled trials.
Fenofibrate alleviates the composition and metabolic pathways of gut microbiota in high-fat diet treated hamsters
Authors: Liu Qifeng 
Published: July 2024

Abstract
Background
Fenofibrate is a compound with diverse biological properties that can be utilized to lower blood lipids. Understanding the impact of the gut microbiota in hyperlipidemia is vital for controlling systemic inflammation and improving serum lipid control. Nevertheless, the specific effects of fenofibrate on the phenotype and gene expression of resident gut bacteria, as well as its influence on the transformation of microbial metabolism into functional networks, remain unclear. In this study, our aimed to examine the gene and metabolic pathways of the gut microbiota in a hamster fed a high-fat diet (HFD) and administered fenofibrate.

Results
In this study, we conducted metagenomic analyses on samples from HFD hamsters treated with fenofibrate. The results indicated that fenofibrate treatments significantly reduce the serum lipid levels in hyperlipidemia hamsters. And the group treated with fenofibrate exhibited higher levels of beneficial bacterial species associated with health, including Bacteroides ovatus, Bifidobacterium animalis, Bacteroides intestinalis, Allobaculum stercoricanis, Lactobacillus reuteri, and Bacteroides acidifaciens, in comparison to the HFD group. Additionally, analysis of metabolic pathways demonstrated that dietary fenofibrate significantly enhanced the biosynthesis of unsaturated fatty acids, glycerophospholipid metabolism, and pyrimidine metabolism, while reducing glyoxylate and dicarboxylate metabolism, tyrosine metabolism, tryptophan metabolism, and nonribosomal peptide structures. Furthermore, these metabolic pathway changes were associated with relative alterations in the abundance of genes from the Kyoto Encyclopedia of Genes and Genomes (KEGG) database, namely K01667, K11358, K13953, K04072, K06131, K00655, K04567, K02864, K06409, K05366, K01867, K21071, and K13292. Moreover, significant changes were observed in related to carbohydrate and antibiotic resistance, such as glycosyltransferase family 51 (GT51) as well as adeC, carA, and MexT.

Conclusions
Dietary fenofibrate exerted significant effects on intestinal flora and genes related to lipid, energy, and amino acid metabolism, ultimately promoting a healthier colonic environment for the host. And these findings contribute to a better understanding of the mechanism of action of fenofibrate and provide a valuable foundation for future experimental and clinical studies, aiming to explore its practical applications.

Published: July 2024

Abstract
Background
Psychiatrists often hesitate to diagnose borderline personality disorder (BPD). While individuals with BPD have reported both positive and negative experiences upon receiving their diagnosis, no study has specifically explored this issue among parents. Parents of children diagnosed with BPD can benefit from recently developed family-support interventions such as the Family Connections program. Our study aimed to explore the experiences of parents learning about their child’s BPD diagnosis and to investigate the impact of the Family Connections program on their experiences.

Methods
This qualitative study, conducted in France following the five-stage IPSE method, involved parents of children with BPD recruited through the Family Connections association in Versailles. We conducted semi-structured interviews and used purposive sampling for data collection until data saturation was reached. Data analysis was performed using a descriptive and structuring approach with NVivo 12 software to elucidate the structure of lived experiences.

Results
The study included 21 parents. The structure of the lived experiences was characterized by three central axes: (1) the long and difficult road to diagnosis; (2) communicating the BPD diagnosis to parents: a necessary step; (3) the pitfalls of receiving the diagnosis. The Family Connections program provided significant support in these areas, particularly in understanding the diagnosis, enhancing communication with their child, and reducing social isolation.

Conclusion
These findings highlight the challenges parents face when receiving a BPD diagnosis for their child and underscore the need for an early, clear, and detailed explanation of the diagnosis. The specific experiences of receiving the diagnosis are indicative of the broader care experience parents undergo and highlight their need and right to be informed, supported, and guided throughout their child’s treatment.

AbstractAcellular dermal matrix (ADM) is one of the most promising scaffold materials due to its ability to retain natural extracellular matrix structure. Micronized acellular dermal matrix (mADM) was prepared with no intact cell nuclei and preserved growth factors by High Hydrostatic Pressure (HHP) approach. And mADM-collagen wound dressings were developed with different proportion of type I collagen and recombinant humanized type III collagen. The porous structure of the mADM-collagen wound dressings made them a good candidate for preventing excessive fluid accumulation, while the collagens with gel-like texture combined with mADM powder to form pasty texture wound dressing, which preserving the moisture at the wound site. Moreover, the paste texture of the mADM-collagen wound dressing was easy to reshape to conform any wound shapes and body contours. Furthermore, the resulted mADM-collagen wound dressings showed good biocompatibility by supporting fibroblasts adhesion and proliferation in vitro. Subsequently, a murine model of full-thickness skin wounds was employed to assess its effects on wound healing. Notably, mADM-75% Col-I exhibited superior effects throughout the wound healing process, specifically it promoted neovascularization, skin appendage growth and new skin regeneration. This formulation closely mimicked the collagen ratio found in healthy skin, facilitating the favorable wound repair. These results indicated the superior performance of this mADM-collagen wound dressing providing an optimal environment for wound healing.

AbstractThe hormonal decline during menopause increases women's risk of chronic diseases. D-limonene, a monoterpene found in the human diet, possesses biological properties related to hypolipemic, antioxidant, anti-inflammatory, and gut microbiota-modulating activities, primarily observed in preclinical studies. Postprandial responses include physiological adaptations to the stress of a nutrient surplus, providing an opportunity to assess metabolic resilience, being a suitable strategy for exploring post-menopause-associated metabolic alterations. Here, we investigated the effects of D-limonene supplementation (2 g/day) on postprandial metabolism in postmenopausal women (n = 9) challenged with a standardized mixed meal in a 3-week single-arm clinical study. Our findings revealed that D-limonene did not induce marked differences in postprandial responses to the dietary challenge. The supplementation with D-limonene induced no alterations in serum lipid/lipoprotein profile or glycemia/insulinemia. D-limonene supplementation did not affect the transient postprandial inflammatory response regarding changes in gene expression of peripheral blood mononuclear cells (PBMC) and circulating inflammatory markers. Nevertheless, D-limonene reduced postprandial levels of lithocholic acid, a gut microbiota-derived bile acid, and regulated the plasma concentrations of selected amino acids, carbohydrate metabolism-derived metabolites, and organic acids. In conclusion, our data do not support the claim that short-term D-limonene supplementation beneficially affects the postprandial metabolism of postmenopausal women.

Published: July 2024

AbstractGlobal Navigation Satellite System (GNSS) can provide an approach for spacecraft autonomous navigation in earth–moon space to make up for the insufficiency of earth-based tracking, telemetry, and control systems. However, its weak power and poor observation geometry near the moon causes new problems. After the GNSS signal characteristics and satellite visibility were evaluated in Phasing Orbit and Lunar Transfer Orbit, we proposed an adaptive Kalman filter based on the Carrier-to-Noise ratio (C/N0) and innovation vector to weaken the influence of GNSS accuracy attenuation as much as possible. The experimental results show that the spacecraft position and velocity accuracy are better than 10 m and 0.1 m/s near the Earth, and better than 50 m and approximately 0.2 m/s near the moon use GNSS with the proposed adaptive algorithms. Additionally, because of the deterioration of navigation performance based on the orbit filter during orbital maneuvering, we used accelerometer data to compensate for the dynamic model to maintain navigation performance. The results of the experiment provide a reference for subsequent studies.
