BMJ Open May 2024This study aimed to analyse the current status, trends and risk factors of disease burden from 1990 to 2019 among Chinese children.
OBJECTIVES
This study aimed to analyse the current status, trends and risk factors of disease burden from 1990 to 2019 among Chinese children.
DESIGN AND PARTICIPANTS
It was a retrospective study on data from the Global Burden of Disease Study 2019 (GBD 2019). Data of disease burden and risk factors were extracted from the GBD 2019. Children were divided into two groups of <5 and 5-14 years. Data were analysed using GBD results query tool, Excel and Pareto analysis.
PRIMARY OUTCOME MEASURES
Disability-Adjusted Life Years (DALYs) and deaths.
RESULTS
The overall disease burden for both children <5 years and those aged 5-14 years significantly decreased from 1990 to 2019. For children aged <5 years, in 2019, the leading cause of deaths and DALYs were 'neonatal disorders', and the top risk factor was 'low birth weight'. Compared with data of 1990, the ranking of causes of deaths and DALYs in 2019 saw the most significant increase for 'HIV/AIDS and sexually transmitted infections' and 'skin and subcutaneous diseases' respectively. Conversely, the ranking of deaths/DALYs causes that dropped most significantly was 'nutritional deficiencies'. For children aged 5-14, in 2019, the leading deaths and DALYs causes were 'unintentional injuries' and 'mental disorders' respectively. The top risk factors were 'alcohol use' and 'short gestation', respectively. The ranking of deaths and DALYs causes rose most significantly were 'HIV/AIDS and sexually transmitted infections' and 'neonatal disorders', respectively. Conversely, the ranking of deaths causes that dropped most significantly were 'other infectious diseases', 'enteric infections' and 'nutritional deficiencies'. For DALYs, the causes that dropped most significantly in ranking were 'other infectious diseases'.
CONCLUSIONS
The disease burden of children has significantly changed from 1990 to 2019, with notable differences between children aged <5 and 5-14 years. To optimise the allocation of health resources, it is necessary to adjust management strategies based on the latest disease burden.

Review
INTRODUCTION
Depressed mood is a psychological state characterised by sadness or loss of interest in activities. Depressed mood is a highly prevalent symptom across major mental disorders. However, there is limited understanding of the burden and management of comorbid depressed mood across major mental disorders. Therefore, this scoping review aims to summarise knowledge on depressed mood among persons with anxiety and/or psychosis. The specific aims are to describe the epidemiology and risk factors of depressed mood as a transdiagnostic target among persons with anxiety and/or psychosis, to identify commonly used outcome measures for depressed mood and to outline initial evidence of psychometric robustness and to identify and summarise the effectiveness of commonly applied depressed mood modification interventions. Our hope is that the proposed review will provide insights into the burden of depressed mood in persons with anxiety and psychosis and help to identify evidence gaps and recommendations for future research.
METHODS AND ANALYSIS
This scoping review will be conducted per Arksey and O'Malley's framework. We will first search for peer-reviewed articles and grey literature published from 2004 to 2023 in PubMed, Scopus, Web of Science, Africa-Wide Information, CINAHL, PsycINFO, Academic Search Premier, Humanities International Complete, Sabinet, SocINDEX, Open Grey and Google Scholar. We will include articles reporting depressed mood (subthreshold depression) among persons with anxiety and/or psychosis. Studies recruiting participants meeting depression diagnostic criteria and those published in non-English languages will be excluded. Two independent researchers will extract the data. We will analyse and chart data collaboratively with researchers with lived experiences of depressed mood.
ETHICS AND DISSEMINATION
This study does not require ethical approval as it is a literature review. The results will be submitted for publication in a peer-reviewed journal.

Infiltration of monocyte-derived cells to sites of infection and injury is greater in males than in females, due in part, to increased chemotaxis, the process of directed cell movement toward a chemical signal. The mechanisms governing sexual dimorphism in chemotaxis are not known. We hypothesized a role for the store-operated calcium entry (SOCE) pathway in regulating chemotaxis by modulating leading and trailing edge membrane dynamics. We measured the chemotactic response of bone marrow derived macrophages (BMDMs) migrating towards complement component 5a (C5a). Chemotactic ability was dependent on sex and inflammatory phenotype (M0, M1, M2), and correlated with SOCE. Notably, females exhibited a significantly lower magnitude of SOCE than males. When we knocked out the SOCE gene, stromal interaction molecule 1 (STIM1), it eliminated SOCE and equalized chemotaxis across both sexes. Analysis of membrane dynamics at the leading and trailing edges showed that STIM1 influences chemotaxis by facilitating retraction of the trailing edge. Using BTP2 to pharmacologically inhibit SOCE mirrored the effects of STIM1 knockout, demonstrating a central role of STIM/Orai-mediated calcium signaling. Importantly, by monitoring the recruitment of adoptively transferred monocytes in an in vivo model of peritonitis, we show that increased infiltration of male monocytes during infection is dependent on STIM1. These data support a model in which STIM1-dependent SOCE is necessary and sufficient for mediating the sex difference in monocyte recruitment and macrophage chemotactic ability by regulating trailing edge dynamics.

Toxoplasma gondii is a foodborne pathogen that can cause severe and life-threatening infections in fetuses and immunocompromised patients. Felids are its only definitive hosts, and a wide range of animals, including humans, serve as intermediate hosts. When the transmissible bradyzoite stage is orally ingested by felids, they transform into merozoites that expand asexually, ultimately generating millions of gametes for the parasite sexual cycle. However, bradyzoites in intermediate hosts differentiate exclusively to disease-causing tachyzoites, which rapidly disseminate throughout the host. Though tachyzoites are well-studied, the molecular mechanisms governing transitioning between developmental stages are poorly understood. Each parasite stage can be distinguished by a characteristic transcriptional signature, with one signature being repressed during the other stages. Switching between stages require substantial changes in the proteome, which is achieved in part by ubiquitination. F-box proteins mediate protein poly-ubiquitination by recruiting substrates to SKP1, Cullin-1, F-Box protein E3 ubiquitin ligase (SCF-E3) complexes. We have identified an F-box protein named Toxoplasma gondii F-Box Protein L2 (TgFBXL2), which localizes to distinct perinucleolar sites. TgFBXL2 is stably engaged in an SCF-E3 complex that is surprisingly also associated with a COP9 signalosome complex that negatively regulates SCF-E3 function. At the cellular level, TgFBXL2-depleted parasites are severely defective in centrosome replication and daughter cell development. Most remarkable, RNAseq data show that TgFBXL2 conditional depletion induces the expression of stage-specific genes including a a large cohort of genes necessary for sexual commitment. Together, these data suggest that TgFBXL2 is a latent guardian of stage specific gene expression in Toxoplasma and poised to remove conflicting proteins in response to an unknown trigger of development.

Review
Developing web-based education sexual and reproductive health (SRH) programs for immigrant women is crucial. This scoping review aims to provide basic data for developing more advanced programs by examining web-based educational program literature. This review considers web-based SRH education programs for adult immigrant women and focuses on their characteristics, instructional strategies, and outcome evaluations. Data will be extracted following the Minimum Initial Service Package (MISP) and Kirkpatrick level and summarized to show future-oriented results while documenting web-based approach evidence for educating immigrant women on SRH. It is expected to provide information for web-based education programs to meet the MISP and develop various evaluation methods. As such, the findings can be used to determine the direction and level of SRH education.

PloS One 2024To assess the attitudes of women towards intimate partner violence (IPV) in Guyana.
BACKGROUND
To assess the attitudes of women towards intimate partner violence (IPV) in Guyana.
METHODS
We used national data from the publicly available Multiple Indicator Cluster Survey (MICS) conducted in Guyana in 2019 for women aged 15 to 49 years. The prevalence of women who agreed that a husband is justified in beating his wife was analyzed. Respondent reasons included if she: "goes out without telling him", "neglects the children", "argues with him", "refuses sex with him", "burns the food", "has another partner", "stays out late/partying", "refuses to cook or clean", "overspends", and/or "he doesn't have access to her cellphone". Descriptive analyses were carried for all the variables. Logistic regression was used to identify factors associated with these 10 respondent reasons, separately and in combination.
RESULTS
The overall prevalence of women's attitudes justifying IPV against women if there was a 'yes' response to any of the 10 reasons was 17.9% (95%CI: 16.6-19.3%), and varied from 2.7% if she "goes out without telling him", "burns the food", or "overspends" to 10.0% if she "has another partner". This prevalence ranged from 10.2% in urban areas to 19.3% in rural areas (p<0.001), and from 16.1% in coastal to 30.1% in interior areas (p<0.001). Similarly, 25.9% of women from the poorest household agreed that a husband has the right in beating his wife for any of the 10 reasons compared to 11.6% of the richest women (11.6%) (p<0.001). Rural place of residence, ethnicity, geographic region, level of education, wealth quintile, ever used of a computer, and frequency of listening to the radio were significant factors associated with women's attitudes justifying IPV against women (p<0.05).
CONCLUSION
Over one-sixth of the respondents agreed that a husband was justified in committing IPV against women in Guyana. Public health programs focusing on geographic locations, ethnicity, and economic status must be implemented to change attitudes justifying IPV and reduce this significant public health challenge.

BACKGROUND
Women living with HIV (WLWH) have high risk of developing cervical cancer. High- risk Human papillomavirus (hrHPV) is the single most important cause of cervical cancer. Vaccination for and early detection of pre-malignant cervical changes, through cervical cancer screening contributes to prevention of cervical cancer. This study sought to determine the prevalence of HPV among WLWH, genotypes present and the risk factors associated with cervical cancer development.
METHODS AND FINDINGS
An analytical cross-sectional study of 250 sexually active women aged 18 years and above, attending HIV clinic at a tertiary health facility in Accra. Demographic data collection and risk factor assessments were done using interviewer-administered questionnaire, and patient records. Cervical swabs were collected and tested for HPV using real-time PCR assays. Genotype analysis was performed on 92 samples. Descriptive statistics and logistic regression analysis were used to establish associations between hrHPV and risk factors among WLWH. Approximately 60% of study participants tested positive for HPV. The prevalence of hr-HPV among WLH was 44.4%. Factors identified to be protective of hrHPV were employment (AOR = 0.19, 95% CI = 0.06, 0.56, p = 0.003) and highly active antiretroviral therapy (HAART) Tenofovir-Lamivudine-Ritonavir-Lopinavir (TLRL) (AOR = 0.30, 95% CI = 0.09, 0.95, p = 0.04). Women with HIV diagnosis within 6 to10 years (AOR = 4.89, 95% CI = 1.05, 22.70, p = 0.043) and diagnosis >10 years (AOR = 8.25, 95% CI = 1.24, 54.84, p = 0.029) had higher odds of hrHPV. Approximately 25% of samples analysed tested positive for hr-HPV group 1 (genotypes 16, 18, 31, 33, 35, 39, 45,51, 52, 56, 58, 69) and 46.8% for multiple HPV genotypes.
CONCLUSION
A high prevalence of genotypes that include high risk genotypes 16 and 18 and multiple HPV infections was found among WLWH. Almost half of the women screened had high-risk HPV and were prone to cervical cancer without their knowledge. Regular HPV screening is recommended for high-risk patient groups.

Haemophilus ducreyi was historically known as the causative agent of chancroid, a sexually-transmitted disease causing painful genital ulcers endemic in many low/middle-income nations. In recent years the species has been implicated as the causative agent of nongenital cutaneous ulcers affecting children of the South Pacific Islands and West African countries. Much is still unknown about the mechanism of H. ducreyi transmission in these areas, and recent studies have identified local insect species, namely flies, as potential transmission vectors. H. ducreyi DNA has been detected on the surface and in homogenates of fly species sampled from Lihir Island, Papua New Guinea. The current study develops a model system using Musca domestica, the common house fly, as a model organism to demonstrate proof of concept that flies are a potential vector for the transmission of viable H. ducreyi. Utilizing a green fluorescent protein (GFP)-tagged strain of H. ducreyi and three separate exposure methods, we detected the transmission of viable H. ducreyi by 86.11% ± 22.53% of flies sampled. Additionally, the duration of H. ducreyi viability was found to be directly related to the bacterial concentration, and transmission of H. ducreyi was largely undetectable within one hour of initial exposure. Push testing, Gram staining, and PCR were used to confirm the identity and presence of GFP colonies as H. ducreyi. This study confirms that flies are capable of mechanically transmitting viable H. ducreyi, illuminating the importance of investigating insects as vectors of cutaneous ulcerative diseases.

The protozoan parasite Cryptosporidium is a leading cause of diarrhea in young children. The parasite's life cycle involves a coordinated and timely progression from asexual to sexual stages, leading to the formation of the transmissible oocyst. Underlying molecular signaling mechanisms orchestrating sexual development are not known. Here, we describe the function of a signaling kinase in Cryptosporidium male gametogenesis. We reveal the expression of Cryptosporidium parvum calcium-dependent protein kinase 5 (CDPK5) during male gamete development and its important role in the egress of mature gametes. Genetic ablation of this kinase results in viable parasites, indicating that this gene is dispensable for parasite survival. Interestingly, cdpk5 deletion decreases parasite virulence and impacts oocyst shedding in immunocompromised mice. Using phosphoproteomics, we identify possible CDPK5 substrates and biological processes regulated by this kinase. Collectively, these findings illuminate parasite cell biology by revealing a mechanism controlling male gamete production and a potential target to block disease transmission.

BACKGROUND
Transgender men and transmasculine youth are at high risk for acquiring HIV. Growing research on transgender men demonstrates increased HIV risk and burden compared with the general US population. Despite biomedical advancements in HIV prevention, there remains a dearth of evidence-based, sexual health HIV prevention interventions for young transgender men. MyPEEPS (Male Youth Pursuing Empowerment, Education, and Prevention around Sexuality) Mobile is a web-based app that builds on extensive formative community-informed work to develop an evidence-based HIV prevention intervention. Our study team developed and tested the MyPEEPS Mobile intervention for 13- to 18-year-old cisgender young men in a national randomized controlled trial, which demonstrated efficacy to reduce sexual risk in the short term-at 3-month follow-up. Trans men and transmasculine youth resonated with basic HIV educational information and sexual scenarios of the original MyPEEPS app for cisgender men, but recognized the app's lack of transmasculine specificity.
OBJECTIVE
The purpose of this study is to detail the user-centered design methods to adapt, improve the user interface, and enhance the usability of the MyPEEPS Mobile app for young transgender men and transmasculine youth.
METHODS
The MyPEEPS Mobile app for young transgender men was adapted through a user-centered design approach, which included an iterative review of the adapted prototype by expert advisors and a youth advisory board. The app was then evaluated through a rigorous usability evaluation.
RESULTS
MyPEEPS Mobile is among the first mobile health interventions developed to meet the specific needs of young transgender men and transmasculine youth to reduce HIV risk behaviors. While many of the activities in the original MyPEEPS Mobile were rigorously developed and tested, there was a need to adapt our intervention to meet the specific needs and risk factors among young transgender men and transmasculine youth. The findings from this study describe the adaptation of these activities through feedback from a youth advisory board and expert advisors. Following adaptation of the content, the app underwent a rigorous usability assessment through an evaluation with experts in human-computer interaction (n=5) and targeted end users (n=20).
CONCLUSIONS
Usability and adaptation findings demonstrate that the MyPEEPS Mobile app is highly usable and perceived as potentially useful for targeting HIV risk behaviors in young transgender men and transmasculine youth.
