Real-world optimization of tunnel lengths in tunneled peripherally inserted central catheters for cancer patients: A multi-center retrospective cohort study

by Yinyin Wu, Wei Ding, Yuying Liu, Qianhong Deng, Fengqin Tao, Hanbin Chen, Chang Chen, Meng Xiao, Bilong Feng

Background

Standardized guidelines for optimal tunnel length in tunneled peripherally inserted central catheters (PICCs) are lacking.

Objectives

The objective of this study was to evaluate the real-world impact of tunnel length on clinical outcomes.

Methods

This retrospective cohort study included 207 cancer patients who received tunneled PICCs, categorized into a control group (tunnel length > 4 cm, n = 134) and an observation group (tunnel length ≤ 4 cm, n = 73). Propensity score matching (PSM) was used to address baseline heterogeneity. Cox regression analyses were used to assess the risk of complication during a 120-day follow-up.

Results

Compared to the control group (tunnel length > 4 cm), the observation group (tunnel length ≤ 4 cm) had a significantly higher adjusted overall complication risk (HR = 2.92, 95% CI: 1.07–7.94, P = 0.036) and unplanned catheter removal rate (4.4% vs. 0.0%, P = 0.027), confirming the safety of longer tunnels despite comparable comfort levels between groups. After PSM, Cox regression analysis showed results consistent with those from the unmatched cohort. Subgroup analyses revealed a reduced risk of complications with longer tunnels in patients with BMI ≤ 25 kg/m² (HR = 0.29, 95% CI: 0.11–0.82), without hypertension (HR = 0.36, 95% CI: 0.13–1.00), without diabetes (HR = 0.38, 95% CI: 0.15–0.97), and with solid tumors (HR = 0.31, 95% CI: 0.11–0.85).

Conclusion

The results show that tunnel lengths > 4 cm reduce overall complications and prolong catheter retention, supporting the implementation of standardized protocols while advocating for personalized adjustments based on BMI, comorbidities, and cancer type.

Multi-omics analysis reveals diagnostic and therapeutic biomarkers for aging phenotypes in ulcerative colitis

by Lei Guo, Jun Ge, Li Cheng, Xinyi Zhang, Zhengzheng Wu, Meili Liu, Hanmei Jiang, Wei Gong, Yi Liu

Background

The incidence of ulcerative colitis (UC) remains high, with an increasing prevalence among elderly patients. Cellular senescence has been widely recognized as a contributor to UC susceptibility; however, the underlying molecular mechanisms remain incompletely understood. This study aimed to identify senescence-associated biomarkers in UC to provide new insight for diagnosis and treatment.

Methods

By integrating transcriptomic data from UC patients with established aging-related databases, we identified aging-associated differentially expressed genes (DEGs). Using weighted gene co-expression network analysis (WGCNA) and Cytoscape, we pinpointed the core genes involved. A diagnostic model for UC was then developed based on these core genes, and their expression patterns were characterized at single-cell resolution. The roles of these genes were ultimately validated through in vitro and animal experiments.

Results

We identified 24 aging-related DEGs in UC, which were primarily implicated in inflammatory responses and cytokine-receptor interactions. Further analyses pinpointed three core genes (CXCL1, MMP9, and STAT1) that were predominantly expressed in macrophages. A diagnostic model constructed using these genes exhibited robust predictive performance. Experimental validation confirmed that the expression levels of all three core genes were significantly upregulated in both a UC mouse model and in macrophages compared to controls. Additionally, pathway analyses revealed elevated levels of CXCL12 and VEGFA in the enriched pathways.

Discussion

Our findings underscore the pivotal roles of CXCL1, MMP9, and STAT1 in UC-associated cellular senescence. The analysis positions these molecules as promising macrophage-mediated diagnostic biomarkers and therapeutic targets. Collectively, this work provides novel insights into UC pathogenesis and lays a foundation for developing precision medicine strategies that target senescence pathways.

Concentration-dependent effects of fermented spent coffee grounds and contrasting effects of earthworms on growth and phytochemicals in medicinal plant <i>Glechoma longituba</i>

by Bing-Nan Zhao, Zi-Yang Xie, Jia-Ning Liu, Xiao-Ran Chen, Xin-Xin Wang, Jia-Yi Li, Rui Zhang, Chao Si

Fermented spent coffee grounds (FSCG) serve as a valuable soil amendment to improve soil structure and fertility, while earthworms play a well-established role in enhancing soil processes and plant growth. However, their combined effects on bioactive compound accumulation in medicinal plants remain unclear. This study investigated the individual and interactive effects of FSCG (0%, 10%, and 20%, v/v) and earthworms (with and without Pheretima guillelmi) on the growth and phytochemical content of Glechoma longituba, a common medicinal herb, under greenhouse conditions. Results showed that 10% FSCG generally promoted plant growth, whereas 20% FSCG generally enhanced the accumulation of total flavonoids, chlorogenic acid, and soluble protein. Earthworms enhanced aboveground biomass and node number but significantly reduced chlorogenic acid content. These findings highlight the potential of FSCG as a sustainable soil amendment in medicinal plant cultivation and underscore the need to consider earthworm activity when optimizing both plant biomass and phytochemical quality.

Risk Factors for Pressure Injuries and Injury Types Among Inpatients in Multi‐Centre Military Hospitals: A Factor Analysis Study

ABSTRACT

Pressure injuries remain a significant concern in military hospital settings, leading to increased morbidity and healthcare costs. Understanding the interplay of multiple risk factors is critical for effective prevention. To identify key risk factors and their combined effects on pressure injury development among inpatients in multi-centre military hospitals using factor analysis. A cross-sectional study was conducted involving 4876 inpatients across multiple military hospitals. Data were collected on 15 potential risk factors, including incontinence, care dependency, mobility limitations, comorbidities, medication use, nutritional status, and demographics. Factor analysis with principal component analysis and varimax rotation was applied, and maximum canonical correlation coefficients were calculated to evaluate the predictive contribution of single and combined factors. Single-factor analysis identified incontinence as the strongest predictor (MaxCanonicalCorr = 0.50126), followed by care dependency (0.31982) and bedridden status (0.30061). Two-factor analysis revealed incontinence combined with care dependency as the highest-performing model (MaxCanonicalCorr = 0.50867). Three-factor models incorporating incontinence, health conditions, and care dependency achieved the greatest predictive capacity (MaxCanonicalCorr = 0.5157), demonstrating that multi-factor interactions enhance risk prediction beyond single-factor effects. Incontinence is the primary modifiable risk factor for pressure injury in military hospital inpatients. Integrating continence management with assessments of functional status and comorbidities can improve early identification of high-risk patients and guide targeted preventive strategies.

A psycho-ecological signal recognition framework for user behavior prediction on digital media platforms

by Lei Xiong, Ke Li, Wendy Siuyi Wong

Background

Digital media usage has become an integral part of daily life, but prolonged or emotionally driven engagement—especially during late-night hours—may lead to concerns about behavioral and mental health. Existing predictive systems fail to account for the nuanced interplay between users’ internal psychological states and their surrounding ecological contexts.

Objective

This study aims to develop a psychologically and ecologically informed behavior prediction model to identify high-risk patterns of digital media usage and support early-stage intervention strategies.

Methods

We propose a Dual-Channel Cross-Attention Network (DCCAN) architecture composed of three layers: signal identification (for psychological and ecological encoding), interaction modeling (via cross-modal attention), and behavior prediction. The model was trained and tested on a dataset of 9,782 users and 51,264 behavior sequences, annotated with labels for immersive usage, late-night activity, and susceptibility to health misinformation.

Results

The DCCAN model achieved superior performance across all three tasks, especially in immersive usage prediction (F1-score: 0.891, AUC: 0.913), outperforming LSTM, GRU, and XGBoost baselines. Ablation studies confirmed the critical role of both psychological and ecological signals, as well as the effectiveness of the cross-attention mechanism.

Conclusions

Incorporating psychological and ecological modalities through attention-based fusion yields interpretable and accurate predictions for digital risk behaviors. This framework shows promise for scalable, real-time behavioral health monitoring and adaptive content moderation on media platforms.

<i>Mycobacterium tuberculosis</i> complex lineages and drug resistance patterns among tuberculosis patients with or without diabetes mellitus in southern Ghana

by Emelia Konadu Danso, Prince Asare, Amanda Yaa Tetteh, Phillip Tetteh, Augustine Asare Boadu, Ivy Naa Koshie Lamptey, Augustina Angelina Sylverken, Kwasi Obiri-Danso, Jane Sandra Afriyie-Mensah, Abraham Adjei, Dorothy Yeboah-Manu

Drug-resistant (DR) tuberculosis (TB) and diabetes mellitus (DM) are intersecting epidemics that complicate management of both diseases and worsen patient outcomes. We conducted a prospective cohort study of 758 GeneXpert-confirmed pulmonary TB patients, of whom 75 had DM. Demographic, clinical, radiographic, and anthropometric data were collected at baseline. Sputum samples were cultured for mycobacterial isolation, and the obtained isolates were characterized for Mycobacterium tuberculosis complex (MTBC) lineage and drug-susceptibility testing using spoligotyping and microplate alamar blue assay. The TB-diabetes (TB-DM) comorbid cohort was older [TB-DM: 53/75 (70.7%) vs. 241/683 (35.3%) aged 41–60 years) (p 

Biopsychosocial factors associated with symptom severity in the overlap of non-erosive reflux disease and epigastric pain syndrome: A multicenter cross-sectional study

by Mi Lv, Hui Che, Jiayan Hu, Wenxi Yu, Zhaoxia Liu, Xiaolin Zhou, Binduo Zhou, Jinyi Xie, Fengyun Wang

Background

The overlap between non-erosive reflux disease (NERD) and epigastric pain syndrome (EPS, a subtype of functional dyspepsia) is common, yet its associated factors remain poorly defined. We aimed to identify factors associated with symptom severity in NERD-EPS overlap, focusing on psychosocial and somatic factors.

Methods

In this multicenter cross-sectional study, 800 patients meeting Rome IV criteria for NERD-EPS overlap were enrolled. Standardized questionnaires assessed gastrointestinal symptoms (GSRS), somatic symptoms (PHQ-15), anxiety/depression (PHQ-4), and sleep quality (SRSS). Multivariable regression models identified factors independently associated with GSRS scores, adjusted for demographics and clinical covariates. Interaction terms were tested to assess whether the association between one factor and GSRS scores varied across different levels of another factor.

Results

Of the 800 patients, 67% were female, and the mean age was (44.50 ± 14.43) years. 67% had mild or more sleep problems, and 47% had anxiety or depression. Somatic symptoms (PHQ-15) showed the strongest association with GSRS scores (β = 0.617, P P P = 0.026). Urban residence (β = 0.071) and mixed labor type (β = −0.066) were also independently associated with symptom burden.

Conclusion

Somatic symptoms, psychological distress, and sleep disturbances were the factors most strongly associated with symptom severity in NERD-EPS overlap, with additional contributions from younger age, male sex, and urban residence. Our findings advocate for integrated biopsychosocial interventions to alleviate symptom burden in this population.

High-protein diets reduce plasma pro-inflammatory cytokines following lipopolysaccharide challenge in Swiss Albino mice

by Hellen W. Kinyi, Charles Kato Drago, Lucy Ochola, Gertrude N. Kiwanuka

Macronutrients serve as principal sources of energy, structural components, and regulators of physiological processes. However, the optimal macronutrient combination for health remains unclear. While previous studies indicate that dietary macronutrient composition influences immune function, many have examined individual nutrients in isolation, failing to reflect the interactive effects of macronutrients. This study addresses this gap by examining how varying ratios of dietary carbohydrates, proteins, and lipids modulate serum cytokine responses to lipopolysaccharide challenge in Swiss albino mice. Male and female Swiss albino mice (n = 6 per group), aged 6–8 weeks, were randomly assigned to six purified isocaloric diets with differing macronutrient ratios for 15 weeks. Body weights were monitored to assess nutritional status. Serum levels of TNF-α, IL-6, IL-1β, and IL-10 were measured in unchallenged mice and after three hours of intraperitoneal LPS administration. Mice fed high-carbohydrate, low-protein diets had the highest weight (33.1 g ± 1.1), while those on high-lipid, low-protein diets had the lowest (28.3 g ± 0.6). Plasma levels of TNF-α and IL-10 varied significantly (p 

A disproportionality analysis of FDA adverse event reporting system (FAERS) events for filgotinib

by Yinli Shi, Shuang Guan, Sicun Wang, Muzhi Li, Yanan Yu, Jun Liu, Weibin Yang, Zhong Wang

Background

Although filgotinib, a selective Janus kinase 1 inhibitor, has been increasingly applied in the treatment of inflammatory diseases, its comprehensive safety profile remains insufficiently characterized. Using data from the FAERS database covering Q1 2014 to Q2 2024, this study attempts to analyze adverse event signals linked to filgotinib and provide guidance for the safe and sensible clinical usage of filgotinib.

Methods

From Q1 2014 to Q2 2024, information on adverse drug events (ADEs) associated with filgotinib was gathered. The reporting odds ratio (ROR), proportional reporting ratio (PRR), Bayesian confidence propagation neural network (BCPNN), and multi-item gamma Poisson shrinker (MGPS) were among the signal detection methods that were employed for analysis following data normalization.

Results

Filgotinib was shown to be the main suspected medication in ADE reports, exposing 103 preferred terms (PTs) in 17 system organ classes (SOCs). Infections, gastrointestinal disorders, and musculoskeletal and connective tissue disorders were the most commonly reported adverse effects. Additionally, atrial fibrillation, alopecia, elevated serum creatinine, blood creatinine increased, pulmonary embolism, epididymitis, respiratory failure, and osteopenia were identified as potential disproportionate reporting signals for filgotinib, although these were not listed in the official drug label. Notable significant signals included large intestine erosion (ROR 2186.05, 95%CI(ROR): 1015.94–4703.86, PRR 2176.18, 95%CI(PRR): 1014.64–4667.42), mesenteric arterial occlusion (ROR 1832.17, 95%CI(ROR): 897.68–3739.48, PRR 1822.71, 95%CI(PRR): 896.17–3707.20), repetitive strain injury (ROR 1149.27, 95%CI(ROR): 363.16–3637.01, PRR 1147.05, 95%CI(PRR): 363.24–3622.15), oligoarthritis (ROR 755.02, 95%CI(ROR): 310.74–1834.54, PRR 752.59, 95%CI(PRR): 310.60–1823.51), and periostitis (ROR 676.03, 95%CI(ROR): 319.36–1431.06, PRR 672.98, 95%CI(PRR): 318.97–1419.87). The subgroup analysis identified obvious sex and age-specific trends in filgotinib-related adverse reactions, emphasizing a higher risk of renal disorders in females, a preponderance of gastrointestinal events in males, and age-dependent trends involving mesenteric occlusion, increased serum creatinine, and immunoglobulin reduction.

Conclusion

While filgotinib demonstrates therapeutic efficacy, it is associated with a range of potential adverse events, underscoring the need for vigilant clinical monitoring. Particular attention should be given to gastrointestinal, cardiovascular, respiratory, and metabolic complications.

Investigating risk factors of hemorrhagic fever of renal syndrome (HFRS) in Qingdao, Shandong province, China

by Ying Li, Jing Jia, Runze Lu, Liyan Dong, Lizhu Fang, Litao Sun, Zongyi Zhang, Qing Duan, Lijie Zhang, Kunzheng Lv, Huilai Ma

Background

Qingdao, a historically high-risk area for hemorrhagic fever with renal syndrome (HFRS) in China, is undergoing agricultural mechanization and urbanization. However, the specific risk factors for HFRS in this context remain unclear. This study sought to determine the risk factors for HFRS in Qingdao.

Methods

Community-based, 1:2 case-control study. Each case was matched with two healthy neighborhood controls based on biological sex, age, and the same neighborhood or village. Univariate and multivariate conditional logistic regression analyses were performed. Furthermore, stratified analyses were performed to explore risk factor heterogeneity between the peak season for Hantaan virus (HTNV) type HFRS (October-January) and other months.

Results

93 cases (73.2%, 93/127) reported from January 2022 to September 2023 and 186 controls completed this questionnaire. Farmers accounted for the highest proportion (68.8%, 64/93). In multivariate logistic regression analysis, there were three significant risk factors for HFRS: piles of firewood and/or grain in residential yards (odds ratio [OR]=3.75, 95% CI: 2.14–6.55), mite and/or flea bites (OR=1.83, 95% CI: 1.06–3.18) and contacting with rats and/or their excreta (OR=1.73, 95% CI: 1.09–2.74); three variables represented significant protective factors for HFRS: frequency of sun exposure for quilts and bedding (OR=0.41, 95% CI: 0.19–0.90), rodent control measures at home (OR=0.50, 95% CI: 0.30–0.81) and knowing the main sources of HFRS transmission (OR=0.58, 95% CI: 0.36–0.90). Stratified analysis revealed that the influence of these factors varied by season, with rodent contact and control measures being particularly salient during the HTNV peak season.

Conclusion

This study provides the first comprehensive evidence of risk and protective factors for HFRS in Qingdao, highlighting the role of rodent control, promoting comprehensive health education, environmental management, and personal protection. However, the results should be interpreted considering the study’s limitations, including a 73.2% response rate and the potential for recall bias.

Investigation on the knowledge-attitude-practice of medical students in controlling emerging infectious diseases: A case study of COVID-19

by Yizhe Yang, Ruifeng Liang, Yan Luo, Doudou Zhu, Yi Liu, Yuyan Guo, Jiafen Zhang, Qiao Niu

Objective

Investigate the Knowledge-Attitude-Practice (KAP) of students from Medical College towards emerging infectious diseases, and assess their impact, can provide a scientific basis and practical guidance for enhancing medico’s prevention and control capabilities.

Methods

A total of 2,395 participants from various grades and majors at Medical University were randomly selected using a stratified cluster sampling method. This cross-sectional study was conducted between April 25 and May 31, 2020, using a self-administered questionnaire developed on the Wenjuanxing platform to assess COVID-19-related knowledge, attitudes, and practices (KAP) among medical students.

Results

A total of 2,245 participants (aged 16–28 years) were included in the study, coming from five medical disciplines: Clinical Medicine, Preventive Medicine, Nursing, Clinical Pharmacy, Health Inspection and Quarantine. The average scores for the COVID-19 epidemiological knowledge and the control measures for the epidemic were 4.92 ± 1.03 and 4.50 ± 0.78, respectively. Among them, the scores of epidemiological knowledge exhibited significant differences in sex, nation, type of dwelling place, major, grade, annual per capita household income, and age. The scores of preventive knowledge significantly differed by sex, major, grade, physical condition, and age. Further, behavioral data indicated that 96.0% of the students thought the pandemic had severely affected their daily life, while >90% maintained consistent mask usage and >80% insisted on health-protective practices. Practice scores finally varied significantly by sex, family structure, and ethnicity.

Conclusions

Altogether, medical students possess certain basic knowledge in controlling emerging infectious diseases, but some still generally suffer from insufficient cognitive depth and anxiety. Colleges can systematically enhance students’ rational cognitive level which include offering specialized courses as well as promoting cutting-edge research achievements, and through standardized operations stabilize their psychological states.

GV effects of diabetes mellitus on clinical outcomes of patients with acute heart failure: A systematic review and meta-analysis

by Linna Zhao, Juanjuan Zhang, Weizhe Liu, Cheng Dai, Aiying Li

Diabetes mellitus (DM) is identified as a potential modifier of clinical outcomes in acute heart failure (AHF), yet its prognostic impact is not fully determined. This systematic review and meta-analysis aimed to assess the prognostic impact of DM on survival outcomes in AHF patients by synthesizing evidence from 26 studies involving 326,928 subjects collected from Cochrane Library, PubMed, Web of Science, and Embase databases up to 1 June 2024. Both prospective/retrospective cohort and case-control studies published since 2000 were included, with outcomes evaluated through multivariate, univariate, and binary analyses using the Newcastle-Ottawa Scale for quality assessment. Multivariate analysis indicated that DM significantly increased the risk of all-cause mortality in AHF patients (cohort studies: HR = 1.21, 95%CI (1.13, 1.29), OR=1.15, 95%CI (1.05, 1.26); case-control studies: HR = 1.39, 95%CI (1.26, 1.53), OR=1.43, 95%CI (1.10, 1.84)]. Univariate analysis confirmed this finding in case-control studies [HR = 1.30, 95%CI (1.01, 1.67)], but not in cohort studies. In both cohort [RR = 1.27, 95%CI (1.12, 1.43)] and case-control [OR=1.21, 95%CI (1.08, 1.35)] studies, DM increased the risk of all-cause mortality. AHF patients with DM had a higher risk of cardiovascular mortality [cohort studies: HR = 1.85, 95%CI (1.46, 2.33); case-control: OR=1.70, 95%CI (1.17, 2.47)]. While multivariate analysis showed no association between DM and in-hospital mortality, case-control studies indicated an increased risk [OR=1.21, 95%CI (1.03, 1.42)]. DM also increased the risk of readmission [cohort studies: HR = 1.32, 95%CI (1.14, 1.53); case-control studies: HR = 1.44, 95%CI (1.23, 1.69); binary data: OR=1.19, 95%CI (1.07, 1.31)].This updated meta-analysis demonstrates that DM imposes significant adverse effects on all-cause mortality, cardiovascular-related mortality, and readmission risk in AHF patients. However, no significant connection was found between diabetes and survival outcomes with respect to the co-endpoint of death or readmission and the endpoint of in-hospital mortality. These findings underscore the necessity for implementing targeted diabetes management within AHF care protocols to enhance clinical outcomes, an essential consideration for future practice.

Using participatory methods to develop a narrative intervention to alleviate distress in children hospitalised with TB in South Africa: The DIMPle project

by Caitlin D. October, Dzunisani P. Baloyi, Lario Viljoen, Rene Raad, Dillon T. Wademan, Megan Palmer, Juli Switala, Michaile G. Anthony, Karen Du Preez, Petra De Koker, Anneke C. Hesseling, Bronwyne Coetzee, Graeme Hoddinott

Children who are hospitalised for tuberculosis (TB) experience challenges that put them at risk of developing emotional, behavioural, and social difficulties. In this methodological paper, we showcase the development of a narrative intervention toolkit with key components of the resulting version 1.0 tool. The study design was participatory and pragmatic, with researchers working with the routine staff of TB hospital wards, children admitted and their caregivers, to iteratively understand and improve children’s experiences of hospitalisation. The project included three phases: (1) a situational analysis to map children and healthcare providers’ perspectives on priorities and potential intervention components, (2) co-development of a beta-version of the intervention, and (3) piloting and incremental refinement toward a version 1.0 of the intervention. The intervention toolkit combined a series of activities alongside the story of ‘Courageous Curly’ to facilitate children’s engagement with their own experiences of hospitalisation, including psychosocial and treatment challenges, captured, and described throughout data collection. We found that dividing the story into short chapters facilitated children’s engagement with the section of story that is being told on a specific day. Each chapter of the story follows/mimics a different stage children can expect during their treatment journey while hospitalised for TB care. Implementation and evaluation of such interventions can mitigate the psychosocial impact of TB in children and inform policies to improve their overall TB care.

Prevalence and determinants of precancerous cervical lesions among women screened for cervical cancer in Africa: A systematic review and meta-analysis

by Berihun Agegn Mengistie, Getie Mihret Aragaw, Tazeb Alemu Anteneh, Kindu Yinges Wondie, Alemneh Tadesse Kassie, Alemken Eyayu Abuhay, Wondimnew Mersha Biset, Gebrye Gizaw Mulatu, Nuhamin Tesfa Tsega

Background

Precancerous cervical lesions, or cervical intraepithelial neoplasia (CIN), represent a significant precursor to cervical cancer, posing a considerable threat to women’s health globally, particularly in developing countries. In Africa, the burden of premalignant cervical lesions is not well studied. Therefore, the main purpose of this systematic review and meta-analysis was to determine the overall prevalence of precancerous cervical lesions and identifying determinants among women who underwent cervical cancer screening in Africa.

Methods

This study followed the Preferred Reporting Item Review and Meta-analysis (PRISMA) guidelines. The protocol for this systematic review and meta-analysis was registered on the International Prospective Register of Systematic Reviews (PROSPERO) (ID: CRD42025645427). We carried out a systematic and comprehensive search on electronic databases such as PubMed and Hinari. In addition, Google Scholar and ScienceDirect were utilized to find relevant studies related to precancerous cervical lesions. Data from the included studies were extracted using an Excel spreadsheet and analyzed using STATA version 17. The methodological quality of the eligible studies was examined using the Joanna Briggs Institute (JBI) assessment tool. Publication bias was checked by using the funnel plot and Egger’s tests. A random-effects model using the Der Simonian Laird method was used to estimate the pooled prevalence of pre-cancerous cervical lesions in Africa. The I-squared and Cochrane Q statistics were used to assess the level of statistical heterogeneity among the included studies.

Results

A total of 112 eligible articles conducted in Africa, encompassing 212,984 study participants, were included in the quantitative meta-analysis. Thus, the pooled prevalence of pre-cancerous cervical lesions in Africa was 17.06% (95% confidence interval: 15.47%−18.68%). In this review, having no formal education (AOR = 4.07, 95% CI: 1.74, 9.53), being rural dweller(AOR = 2.38, 95% CI: 1.64, 3.46), history of STIs (AOR = 3.94, 95% CI: 2.97, 5.23), history of having multiple partners (AOR = 2.73, 95% CI: 2.28, 3.28), early initiation of coitus (AOR = 2.77, 95% CI: 2.11, 3.62), being HIV-seropositive women (AOR = 3.33, 95% CI: 2.32, 4.78), a CD4 count Conclusions

In Africa, the overall prevalence of pre-cancerous cervical lesions is high (17%). The findings of this review highlight that health professionals, health administrators, and all other concerned bodies need to work in collaboration to expand comprehensive cervical cancer screening methods in healthcare facilities for early detection and treatment of cervical lesions. In addition, increasing community awareness and health education, expanding visual inspection of the cervix with acetic acid in rural areas, offering special attention to high-risk groups (HIV-positive women), encouraging adherence to antiretroviral therapy for HIV-positive women, overcoming risky sexual behaviors and practices, and advocating early detection and treatment of precancerous cervical lesions.

Sugar-sweetened beverage/snack consumption and its determinants among infant and young children aged 6–23 months in twelve Sub-Saharan African countries: Evidence from 2019–2023 Demographic Health Survey data

by Birtukan Gizachew Ayal, Abebe Kassa Geto, Sefineh Fenta Feleke, Ali Yimer, Atitegeb Abera Kidie, Natnael Amare Tesfa, Esuyawkal Mislu, Molla Hailu, Hassen Ahmed Yesuf

Background

Sugar-sweetened beverages or snacks are limited in nutritional value. Excess consumption of sugar-sweetened beverages or snacks in early childhood is associated with inadequate micronutrient intake, being overweight or obese, and developing chronic diseases later in life. There is scarcity of information specific to sugar-sweetened beverages or snacks consumption prevalence and its determinants in Sub-Saharan Africa Countries. This study aimed to determine the pooled prevalence of sugar-sweetened beverage or snack consumption and its determinants among infants and young children aged 6–23 months.

Methods

A cross-sectional study design was conducted using demographic and health survey data conducted from 2019 to 2023 from twelve Sub-Saharan African countries. A weighted sample of 23,145 children aged 6–23 months was included in the study. Multilevel mixed-effects logistic regression analysis was used to determine the factors associated with the dependent variable. The level of statistical significance was declared with a p-value  Results

The pooled prevalence of Sugar-sweetened beverage or snack consumption was 25.40% (95% CI: 24.84% − 25.96%). In multilevel multivariable logistic regression analysis, children aged between 9−11(AOR = 1.95 95% CI: 1.62, 2.35), 12–17(AOR = 2.83; 95% CI: 2.26, 3.54), and 18−23 months (AOR = 3.77;95% CI: 3.07, 4.63), media exposure (AOR = 1.59; 95% CI:1.28, 1.98), children from households with middle (AOR = 1.39; 95% CI: 1.11, 1.73) and rich (AOR = 2.31; 95% CI: 1.87, 2.85) wealth status, post natal checkup (AOR = 1.18; 95%CI:1.05,1.33), maternal ANC visit (AOR = 1.60; 95% CI: 1.15, 2.22), and high community media exposure ((AOR = 2.22;95%CI:1.65,5.81) were positively associated significant factors whereas currently breast feeding children (AOR = 0.70; 95% CI: 0.59,0.82), older age at first birth (AOR = 0.88,95% CI: 0.81, 0.96), presences of more than one under-5 children in the household (AOR = 0.89, 95% CI: 0.80, 0.99), mothers don’t perceive distance to health facility as big problem (AOR = 0.86; 95% CI:0.76, 0.98), and children reside in rural (AOR = 0.83;95%CI:0.68,0.95) were negatively associated with sugar sweetened beverage or snack consumption.

Conclusion

In this study, one out of four children consumed sugar-sweetened beverages or snacks. Current age of child, current breastfeeding status of child, media exposure, wealth index, maternal age at first birth, post natal checkup, maternal ANC visit, number of under-five children in the household, distance to health facility, place of residence, and community level media exposure were significant factors with sugar-sweetened beverage or snack consumption. Therefore, it is recommended to raise awareness about the health risks of sugar-sweetened beverage and snack consumption, enforce restrictions on their advertisement, strengthen nutrition-focused counseling within maternal and child health services with special attention for older age children, promote breastfeeding, and give special attention to challenges related to health facility accessibility, and support for young mothers.

Identification and validation of palmitoylation-related signature genes based on machine learning for prostate cancer

by Qijun Wo, Jiafeng Shou, Jun Shi, Lei Shi, YunKai Yang, Yifan Wang, Liping Xie

Prostate cancer (PCa) remains a leading cause of cancer-related mortality in men, with challenges in diagnosis and treatment due to tumor heterogeneity. This study identifies palmitoylation-related signature genes as potential diagnostic and therapeutic targets. Integrating GEO datasets, six differentially expressed genes (DEGs) linked to palmitoylation were identified. Machine learning algorithms (LASSO, RF, SVM) selected three core genes: TRPM4, LAMB3, and APOE. A diagnostic model based on these genes achieved an AUC of 0.929, demonstrating robust accuracy in distinguishing PCa from normal tissues. Functional analysis revealed roles in lipid metabolism and immune modulation, with ssGSEA highlighting correlations between key genes and immune cell infiltration. Experimental validation showed that LAMB3 overexpression suppressed PCa cell proliferation, migration, and invasion, while knockdown enhanced these processes. Molecular docking identified diethylstilbestrol as a potential therapeutic agent targeting LAMB3 and APOE. These findings emphasize the clinical relevance of palmitoylation-related genes in PCa diagnosis and therapy, offering novel biomarkers and insights for personalized treatment strategies.

Epidemiology of sexual violence against adults and children before and during the COVID-19 pandemic in the Eastern Cape, South Africa: a retrospective cross-sectional study

Por: Kwinana · N. · Masilela · C. · Adeniyi · O. V.
Objective

To examine the epidemiological patterns and trends of sexual violence against adults and children before and during the COVID-19 pandemic in the Buffalo City and Amathole districts of the Eastern Cape Province, South Africa.

Design

Observational, retrospective, cross-sectional study based on a review of medical records of survivors of sexual violence who reported for healthcare between January–December 2019 and January–December 2020.

Setting

The study was conducted in two healthcare facilities in the Buffalo City and Amathole districts of the Eastern Cape Province, South Africa.

Participants

A total of 1957 survivors of sexual violence presented for healthcare at the two healthcare facilities during the study period. Inclusion criteria were survivors of all ages with confirmed cases of sexual violence; records with no evidence of sexual violence were excluded.

Primary and secondary outcome measures

Primary outcome measures were prevalence and distribution of sexual violence before and during the COVID-19 pandemic. The secondary outcome measures were demographic characteristics of survivors (age, sex and ethnicity), perpetrator identity and location of incidents.

Results

The majority of survivors were female (93.6%), and 49% were under 18 years of age. Most were Black (96.3%) and resided in rural (45.6%) or semiurban (45.6%) areas. Perpetrator identity was unknown in 42.5% of cases. Among known perpetrators, non-partners such as neighbours (22.5%) and family members (13.6%) were most common. More cases were reported pre-pandemic (n=930; 60.5%) compared with during the pandemic (n=608; 39.5%). During the pandemic, 45.0% of cases occurred in the perpetrator’s home, and 53.7% occurred in rural settings. Most pandemic-period cases (63.1%) were reported during alert level 1, when most social and economic activities had resumed.

Conclusions

Overall, there was a high rate of sexual violence, with trends correlating with the extent of COVID-19 restrictions; the highest rates were reported pre-pandemic and during alert level 1. These findings highlight the importance of prioritising the safety of women and children and informing protective strategies in both rural and urban areas during future emergency responses.
