Published: July 2024

Abstract
Background
Increasing evidence suggests that leptin is involved in the pathology of autism spectrum disorder (ASD). In this study, our objective was to investigate the levels of leptin in the blood of children with ASD and to examine the overall profile of adipokine markers in ASD through meta-analysis.

Methods
Leptin concentrations were measured using an enzyme-linked immunosorbent assay (ELISA) kit, while adipokine profiling, including leptin, was performed via meta-analysis. Original reports that included measurements of peripheral adipokines in ASD patients and healthy controls (HCs) were collected from databases such as Web of Science, PubMed, and Cochrane Library. These studies were collected from September 2022 to September 2023 and followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Standardized mean differences were calculated using a random effects model for the meta-analysis. Additionally, we performed meta-regression and explored heterogeneity among studies.

Results
Our findings revealed a significant increase in leptin levels in children with ASD compared to HCs (p = 0.0319). This result was consistent with the findings obtained from the meta-analysis (p < 0.001). Furthermore, progranulin concentrations were significantly reduced in children with ASD. However, for the other five adipokines analyzed, there were no significant differences observed between the children with ASD and HCs children. Heterogeneity was found among the studies, and the meta-regression analysis indicated that publication year and latitude might influence the results of the meta-analysis.

Conclusions
These findings provide compelling evidence that leptin levels are increased in children with ASD compared to healthy controls, suggesting a potential mechanism involving adipokines, particularly leptin, in the pathogenesis of ASD. These results contribute to a better understanding of the pathology of ASD and provide new insights for future investigations.

Abstract
Background
Several studies have demonstrated the population-level effectiveness of oral PrEP in reducing the risk of HIV infection. However, oral PrEP utilization among MSM in China remains below 1%. While existing literature has primarily focused on oral PrEP preference and willingness, there is limited exploration of the underlying factors contributing to oral PrEP cessation in China. This study aims to fill this gap by investigating the factors associated with oral PrEP cessation among MSM in China.

Methods
Assisted by MSM community organizations, we collected 6,535 electronic questionnaires from 31 regions across China, excluding Taiwan, Hong Kong, and Macau. The questionnaire focused on investigating MSM's awareness, willingness, usage, and cessation of oral PrEP. Additionally, 40 participants were randomly chosen for key informant interviews. These qualitative interviews aimed to explore the reasons influencing MSM discontinuing oral PrEP.

Results
We eventually enrolled 6535 participants. Among the 685 participants who had used oral PrEP, 19.70% (135/685) ceased oral PrEP. The results indicated that individuals spending > ¥1000 on a bottle of PrEP (aOR = 2.999, 95% CI: 1.886–4.771) were more likely to cease oral PrEP compared to those spending ≤ ¥1000. Conversely, individuals opting for on-demand PrEP (aOR = 0.307, 95% CI: 0.194–0.485) and those using both daily and on-demand PrEP (aOR = 0.114, 95% CI: 0.058–0.226) were less likely to cease PrEP compared to those using daily PrEP. The qualitative analysis uncovered eight themes influencing oral PrEP cessation: (i) High cost and low adherence; (ii) Sexual inactivity; (iii) Lack of knowledge about PrEP; (iv) Trust in current prevention strategies; (v) Poor quality of medical service and counseling; (vi) PrEP stigma; (vii) Partner and relationship factors; (viii) Access challenges.

Conclusions
The cessation of oral PrEP among MSM in China is associated with various factors, including the cost of oral PrEP medication, regimens, individual perception of HIV risk, stigma, and the quality of medical services. It is recommended to provide appropriate regimens for eligible MSM and develop tailored combinations of strategies to enhance PrEP awareness and acceptance among individuals, medical staff, and the MSM community. The findings from this study can support the refinement of HIV interventions among MSM in China, contributing to efforts to reduce the burden of HIV in this population.

Abstract
Background
Norovirus gastroenteritis outbreaks were common in schools and kindergartens and were more related to faculty knowledge, attitude, and practice level. Gastroenteritis outbreaks caused by norovirus in educational institutions were the prominent cause of Public Health Emergency Events in China. This study aimed to explore the transformation in the contribution of KAP items related to outbreak prevention before and after intervention and the impact of demography factors on the intervention.

Methods
This study sampled 1095 kindergarten and 1028 school staff in Shenzhen, China. We created a questionnaire consisting of 35 items in 4 parts, and each item was rated on a scale of 1–5 according to the accuracy. Univariate analysis of non-parametric tests and binary logistic regression were used to estimate the score difference on demographic characteristics, each item and KAP. The odds ratios (OR) with 95% confidence and intervals (CI) for the association between statistical indicators were mainly used to explain the effects before and after intervention.

Results
Overall, 98.72% and 74.9% of the kindergarten and school participants were female, and all respondents had the highest scores difference of practice. Following intervention, univariate analysis indicated that primary school and female respondents achieved higher knowledge scores. Staff age beyond 35 (OR = 0.56, CI:0.34–0.92; OR = 0.67, CI:0.50–0.90) and with more than ten years of service (OR = 0.58, CI:0.36–0.91; OR = 0.38, CI:0.17–0.84) demonstrated a significantly lower post-intervention score for attitude and practice in both kindergartens and schools. The staff members exhibited a general lack of familiarity with the transmission of aerosols and the seasonal patterns of NoVs diarrhea pandemics. Item analysis revealed that kindergarten staff aged 26 and above demonstrated superior performance in terms of the efficacy of medical alcohol for inactivation (OR = 1.93, CI:1.13–3.31) and management strategies for unexplained vomiting among students (OR = 1.97, CI:1.21–3.18). Private school personnel displayed more significant improvement in their practices following educational interventions. School administrators' negative attitudes were primarily evident in their perspectives on morning inspections (OR = 0.11, CI:0.05–0.84).

Conclusions
The potential negative impact of faculty age on NoVs-related knowledge can be mitigated by the positive attitudes fostered through seniority. Furthermore, it is imperative to urgently address the lack of knowledge among administrators, and the identification and treatment of vomiting symptoms should be emphasized as crucial aspects of school prevention strategies. Therefore, education authorities should implement comprehensive public health interventions in the future.
Seminal Papers in Urology: Darolutamide and survival in metastatic, hormone-sensitive prostate cancer
Authors: Oh Claris , O’Callaghan Michael 
Published: July 2024

AbstractThe ARASENS trial recruited 1306 men with metastatic hormone sensitive prostate cancer. It investigated the effect of androgen deprivation therapy (ADT) and systemic therapy docetaxel in combination with a third novel drug – daralutamide, compared with placebo on overall survival. Triple therapy with ADT, docetaxel and darolutamide resulted in improved overall survival rates as compared with ADT, docetaxel and placebo (HR 0.68; 95% CI, 0.57–0.80; p < 0.001). The side effect profile for both treatments was similar. This randomised, double blinded, placebo controlled study, was assessed to have a low risk of bias using the Cochrane Risk of Bias 2 tool.
Comparative analysis of genetic risk scores for predicting biochemical recurrence in prostate cancer patients after radical prostatectomy
Authors: Hsieh Ai-Ru , Luo Yi-Ling , Bao Bo-Ying , Chou Tzu-Chieh 
Published: July 2024

Abstract
Background
In recent years, Genome-Wide Association Studies (GWAS) has identified risk variants related to complex diseases, but most genetic variants have less impact on phenotypes. To solve the above problems, methods that can use variants with low genetic effects, such as genetic risk score (GRS), have been developed to predict disease risk.

Methods
As the GRS model with the most incredible prediction power for complex diseases has not been determined, our study used simulation data and prostate cancer data to explore the disease prediction power of three GRS models, including the simple count genetic risk score (SC-GRS), the direct logistic regression genetic risk score (DL-GRS), and the explained variance weighted GRS based on directed logistic regression (EVDL-GRS).

Results and Conclusions
We used 26 SNPs to establish GRS models to predict the risk of biochemical recurrence (BCR) after radical prostatectomy. Combining clinical variables such as age at diagnosis, body mass index, prostate-specific antigen, Gleason score, pathologic T stage, and surgical margin and GRS models has better predictive power for BCR. The results of simulation data (statistical power = 0.707) and prostate cancer data (area under curve = 0.8462) show that DL-GRS has the best prediction performance. The rs455192 was the most relevant locus for BCR (p = 2.496 × 10–6) in our study.
Prevalence of clinical characteristics of lipodystrophy in the US adult population in a healthcare claims database
Authors: Yang Seonkyeong , Knox Caitlin 
Published: July 2024

Abstract
Background
Lipodystrophy is characterized by progressive loss of adipose tissue and consequential metabolic abnormalities. With new treatments emerging for lipodystrophy, there is a growing need to understand the prevalence of specific comorbidities that may be commonly associated with lipodystrophy to contextualize the natural history of lipodystrophy without any disease modifying therapy.

Objective
To examine the risk of specific clinical characteristics in people living with lipodystrophy (LD) in 2018–2019 compared with the general US population, among the commercially insured US population.

Methods
A retrospective cohort study was conducted using the 2018–2019 Clinformatics® Data Mart database. An adult LD cohort (age ≥ 18 years) with at least ≥ 1 inpatient or ≥ 2 outpatient LD diagnoses was created. The LD cohort included non-HIV-associated LD (non-HIV-LD) and HIV-associated LD (HIV-LD) subgroups and compared against age- and sex-matched control groups with a 1:4 ratio from the general population with neither an LD or an HIV diagnosis using odds ratios (ORs) with 95% confidence intervals.

Results
We identified 546 individuals with non-HIV-LD (mean age, 60.3 ± 14.9 years; female, 67.6%) and 334 individuals with HIV-LD (mean age, 59.2 ± 8.3 years; female, 15.0%) in 2018–2019. Compared with the general population, individuals with non-HIV-LD had higher risks (odds ratio [95% confidence interval]) for hyperlipidemia (3.32 [2.71–4.09]), hypertension (3.58 [2.89–4.44]), diabetes mellitus (4.72 [3.85–5.79]), kidney disease (2.78 [2.19–3.53]), liver fibrosis or cirrhosis (4.06 [1.66–9.95]), cancer (2.20 [1.59–3.01]), and serious infections resulting in hospitalization (3.00 [2.19–4.10]). Compared with individuals with HIV, those with HIV-LD have higher odds of hypertension (1.47 [1.13–1.92]), hyperlipidemia (2.46 [1.86–3.28]), and diabetes (1.37 [1.04–1.79]).

Conclusions
LD imposes a substantial burden on affected individuals due to a high prevalence of metabolic comorbidities and other complications as compared with the general non-LD population. Future longitudinal follow-up studies investigating the causality between LD and observed comorbidities are warranted.

Authors: Tan Rukeng , Zhu Xinyu , Chen Sishi , Zhang Jie , Liu Zhixin , Li Zhengshi , Fan Hang , Wang Xi , Yang Le 
Published: July 2024

Abstract
Objectives
This study investigated the effectiveness of a deep convolutional neural network (CNN) in diagnosing and staging caries lesions in quantitative light-induced fluorescence (QLF) images taken by a self-manufactured handheld device.

Methods
A small toothbrush-like device consisting of a 400 nm UV light-emitting lamp with a 470 nm filter was manufactured for intraoral imaging. A total of 133 cases with 9,478 QLF images of teeth were included for caries lesion evaluation using a CNN model. The database was divided into development, validation, and testing cohorts at a 7:2:1 ratio. The accuracy, sensitivity, specificity, positive predictive value, negative predictive value, and area under the receiver operating characteristic curve (AUC) were calculated for model performance.

Results
The overall caries prevalence was 19.59%. The CNN model achieved an AUC of 0.88, an accuracy of 0.88, a specificity of 0.94, and a sensitivity of 0.64 in the validation cohort. They achieved an overall accuracy of 0.92, a sensitivity of 0.95 and a specificity of 0.55 in the testing cohort. The model can distinguish different stages of caries well, with the best performance in detecting deep caries followed by intermediate and superficial lesions.

Conclusions
Caries lesions have typical characteristics in QLF images and can be detected by CNNs. A QLF-based device with CNNs can assist in caries screening in the clinic or at home.

Trial registration
The clinical trial was registered in the Chinese Clinical Trial Registry (No. ChiCTR2300073487, Date: 12/07/2023).

Authors: Gümrükçü Zeynep , Karabağ Mert 
Published: July 2024

Abstract
Background/purpose
Oral cancer, including malignancies of the tongue, lips, floor of the mouth, cheek mucosa, gums, palate, and oropharynx, is life-threatening. Early diagnosis and appropriate treatment are crucial for long-term survival. Dentists frequently encounter oral cancers due to the nature of their work. This study aimed to evaluate the knowledge and experience of dentists in Turkey regarding oral cancers.

Materials and methods
A total of 361 participants were included in the study, and survey questions were sent via email. The survey consisted of 16 questions measuring demographic data and knowledge about oral cancerous lesions. Participants were grouped based on their specialization and knowledge level, and differences in responses among groups were examined.

Results
Only 21.3% of the participants felt they had sufficient knowledge and experience about oral cancerous lesions. Overall, the correct answer rates indicated a moderate level of knowledge and experience. When grouped by specialization, oral surgeons had the highest accuracy in their responses (p < 0.05).

Conclusion
Dentists are the professional group that most frequently encounters clinically oral cancerous lesions. Therefore, it is critically important for them to be knowledgeable and experienced to reduce morbidity and mortality through early diagnosis. This study evaluated the knowledge status of dentists in Turkey regarding oral cancer and highlighted the need for improved education.
Improving lung point-of-care ultrasound (POCUS) training and accreditation - a multidisciplinary, multi-centre and multi-pronged approach to development and delivery using the action learning process
Authors: Tan Mark ZY , Brunswicker Annemarie , Bamber Harry , Cranfield Alistair , Boultoukas Evangelos , Latif Sam 
Published: July 2024

Abstract
Background
Point-of-Care Ultrasound (POCUS) consists of a range of increasingly important imaging modalities across a variety of specialties. Despite a variety of accreditation pathways available in the UK, lung POCUS training remains difficult to deliver and accreditation rates remain suboptimal. We describe a multidisciplinary, multi-centre, and multi-pronged approach to lung POCUS education within a region.

Methods
A survey was conducted in a region. From these results, bottlenecks were identified for improvement. We utilised key stages in an established accreditation pathway, and the Action Learning process. Analysing participant feedback, consensus amongst the team, regional educational needs, and leveraging the expertise within the faculty, we implemented several solutions which were multidisciplinary, multi-centre, and multi-pronged. We also set up a database across several accreditation pathways to facilitate supervision and assessment of rotational trainees.

Results
Utilising the Action Learning process, we implemented several improvements at elements of the lung ultrasound accreditation pathways. An initial regional survey identified key barriers to accreditation: lack of courses (52%), lack of mentors (93%), and difficulty arranging directly supervised scans (73%). A multidisciplinary team of trainers was assembled. Regular courses were organised and altered based on feedback and anecdotal educational needs within the region. Courses were set up to also facilitate continuing professional development and exchange of knowledge and ideas amongst trainers. The barrier of supervision was removed through the organisation of regular supervision sessions, facilitating up to fifty scans per half day per trainer. We collected feedback from courses and optimised them. Remote mentoring platforms were utilised to encourage asynchronous supervision. A database of trainers was collated to facilitate triggered assessments. These approaches promoted a conducive environment and a commitment to learning. Repeat survey results support this.

Conclusion
Lung ultrasound accreditation remains a complex educational training pathway. Utilising an education framework, recruiting a multidisciplinary team, ensuring a multi-pronged approach, and fostering a commitment to learning can improve accreditation success.
Interaction between overconfidence effects and training formats in nurses’ education in hand hygiene
Authors: Seidel-Fischer Julia , Trifunovic-Koenig Milena , Gerber Bianka , Otto Baerbel , Bentele Michael , Fischer Martin R. , Bushuven Stefan 
Published: July 2024

Abstract
Background
Undergraduate training in hand hygiene is a keystone of infection control. Several studies have shown overconfidence effects in hand hygiene practices, which can impair metacognition. We hypothesized that overconfidence might be prevalent in the early education stages of nursing students and that these effects could be reduced through frequent interactive learning formats, such as learning groups.

Methods
We conducted a multicenter cross-sectional questionnaire with 196 German nursing students, including general, surgical, and anesthetic nursing specializations.

Results
Overconfidence was observed in nursing students across all specialties and years of education. The cluster analyses showed three different types of learners: two characterized by overconfidence and one demonstrating justifiable confidence. Furthermore, the moderation analysis indicated that providing feedback and promoting metacognition regarding students’ learning achievements could mitigate overplacement, particularly through the frequent implementation of interactive teaching formats.

Discussion
Despite some limitations, these findings highlight the prevalence of overconfidence effects in nursing students, the presence of different learning profiles, and the importance of incorporating feedback within interactive learning formats concerning hand hygiene. Accordingly, educators need to be trained and supervised to deliver these learning formats and provide feedback to students effectively.
Is palliative care a utopia for older patients with organ failure, dementia or frailty? A qualitative study through the prism of emergency department admission
Authors: Bourmorck Delphine , Pétré Benoit , de Saint-Hubert Marie , De Brauwer Isabelle 
Published: July 2024

Abstract
Background
Nearly three out of four older people will use the emergency department (ED) during their last year of life. However, most of them do not benefit from palliative care. Providing palliative care is a real challenge for ED clinicians who are trained in acute, life-saving medicine. Our aim is to understand the ED’s role in providing palliative care for this population.

Methods
We designed a qualitative study based on 1) interviews – conducted with older patients (≥ 75 years) with a palliative profile and their informal caregivers – and 2) focus groups – conducted with ED and primary care nurses and physicians. Palliative profiles were defined by the Supportive and Palliative Indicators tool (SPICT). Qualitative data was collected in French-speaking Belgium between July 2021 and July 2022. We used a constant inductive and comparative analysis.

Results
Five older patients with a palliative profile, four informal caregivers, 55 primary and ED caregivers participated in this study. A priori, the participants did not perceive any role for the ED in palliative care. In fact, there is widespread discomfort with caring for older patients and providing palliative care. This is explained by multiple areas of tensions. Palliative care is an approach fraught with pitfalls, i.e.: knowledge and know-how gaps, their implementation depends on patients’(co)morbidity profile and professional values, experiences and type of practice. In ED, there are constant tensions between emergency and palliative care requirements, i.e.: performance, clockwork and needs for standardised procedures versus relational care, time and diversity of palliative care projects. However, even though the ED’s role in palliative care is not recognised at first sight, we highlighted four roles assumed by ED caregivers: 1) Investigator, 2) Objectifier, 3) Palliative care provider, and 4) Decision-maker on the intensity of care. A common perception among participants was that ED caregivers can assist in the early identification of patients with a palliative profile.

Conclusions
Currently, there is widespread discomfort regarding ED caregivers caring for older patients and providing palliative care. Nonetheless, ED caregivers play four roles in palliative care for older patients. In the future, ED caregivers might also perform the role of early identifier.
