Objective: The study aimed to explore the association between area-based coverage of community services and the incidence of self-harm, which will provide an evaluation framework for the support of self-harm.

Methods: Enhanced two-Step floating catchment area method was used to estimate the centersto- population ratio and geographical accessibility adjusted by a distance-decay function. Spearman's rank coefficient was used to examine the association between the self-harm rate and adjusted accessibility index.

Malignant ascites of epithelial ovarian cancer is a metastatic tumor microenvironment in which large amounts of disseminated single cells (DSCs) and disseminated tumor cell clusters (DTCCs) are commonly observed. The tumor cell clusters are known to be more aggressive than individual tumor cells in cancer metastasis; however, little is known about the mechanism. Applying single-cell epithelial-to-mesenchymal transition (EMT)-related transcriptional analysis in 120 DSCs and 195 intra-cluster cells from 27 DTCCs, we demonstrated that DTCCs were heterogeneous cellular units comprised of epithelial tumor cells, leukocytes, and cancer-associated fibroblasts (CAFs).

Rapid repeat pregnancy (RRP) often occurs in teenage and young mothers. Mothers with a history of RRP are more likely to experience high stress increasing their risk of child maltreatment. Despite these challenges, some mothers can continue to cope adaptively.

Objectives: To describe the mortality patterns, comorbidities, and attendance at accident and emergency departments among children with Down syndrome in Hong Kong.

Study Design: This is a population-based, retrospective cohort study of live births of children with Down syndrome delivered between 1995 and 2014, as identified from territory-wide hospitalization data in Hong Kong. The Kaplan-Meier product limit method was adopted to estimate the survival probabilities of children with Down syndrome by selected demographic and clinical characteristics.

Background And Objectives: Human papillomavirus (HPV) vaccination and cervical screening prevent cervical cancer effectively. However, there are concerns whether vaccination leads to high-risk sexual behaviors and less intention for cervical screening. We aimed to evaluate the influence of HPV vaccination on high-risk sexual behaviors, and intention for cervical screening among young Chinese females.

Background: The study aimed to examine the impact of household composition and satisfaction with family life on sexual behaviours among high school male and female students (aged 11-22 years) in Hong Kong.

Method: High schools were randomly selected, and the final sample comprised 25 schools. Students were divided into two groups ('living with both biological parents' vs 'not living with both biological parents').

Background: Antigen-specific T cell immune responses play a pivotal role in resolving acute and chronic hepatitis C virus (HCV) infections. Currently, no prophylactic or therapeutic vaccines against HCV are available. We previously demonstrated the preclinical potency of therapeutic HCV vaccines based on recombinant Semliki Forest virus (SFV) replicon particles.

Intimate partner violence (IPV) against women negatively impacts infant health. However, its impact on infant's biology, in particular on telomere length (TL) is unknown. The aim of this study was to examine the association between IPV against women before childbirth and cord blood TL in their newborn.

This study aimed (i) to compare the performance of the BD Onclarity human papillomavirus (HPV) assay with the Cobas HPV test in identifying cervical intraepithelial neoplasia 2/3 or above (CIN2/3+) in an Asian screening population and (ii) to explore improving the cervical cancer detection specificity of Onclarity by machine learning. We tested 605 stratified random archived samples of cervical liquid-based cytology samples with both assays. All samples had biopsy diagnosis or repeated negative cytology follow-up.

Objective: This study aimed at exploring the attempters' perception of community social services included any barriers to seeking help and services.

Method: The participants were patients with self-harming behavior aged 15 years or above. A set of guiding questions were designed to explore the general barriers and accessibility to community social services.

Objective: To determine the mortality, morbidity, types of intracranial hemorrhages, and factors associated with length of stay (LOS) associated with accidental traumatic brain injury (TBI) at a pediatric intensive care unit (PICU) of a regional trauma center in an Asian city.

Methods: This study is a retrospective review of types of head injury, mortality and morbidity demographics of patients admitted to a PICU with TBI. All patients with accidental TBI were included, namely road traffic injury (RTI) and fall, and their demographics compared.

Uterine yolk sac tumors have gained increased recognition in recent years. The current study is a multi-faceted examination of yolk sac tumor-like phenotypes in endometrial tumors, based on an analysis of 3 groups of uterine tumors: Group 1: 9 endometrial tumors that had been classified as yolk sac tumor, or as having a yolk sac tumor component, were assessed with a 35-marker immunohistochemical panel, with the goal of defining their immunophenotypic spectrum; Group 2, comprised of 70 endometrial carcinomas of various histotypes, were analyzed for their expression of SALL4, Glypican-3, and AFP, to assess the specificity of these markers for yolk sac tumors relative to endometrial carcinomas; Group 3, comprised of 626 archived cases of endometrial carcinoma/carcinosarcoma, reviewed to define the frequency of yolk sac tumor-like morphology therein. Yolk sac tumor areas in the Group 1 cases were consistently immunoreactive for SALL4 and Glypican-3; variably positive for AFP (89%), Villin (89%), PLAP (78%), 34βE12 (67%), CAM 5.

The present study seeks to explore the intersectionality of ethnicity/race and socioeconomic status (SES) among ethnic/racial minority adolescents in their developmental contexts, examining its implications for sleep disparities and the roles of discrimination and ethnic/racial identity (ERI; i.e., adolescents' understanding and feelings about who they are in relation to their ethnic/racial group).

A key to successful metastasis is the formation of new vasculature, known as angiogenesis. Therefore, it is of great interest to unravel the underlying molecular mechanisms of tumor angiogenesis. Cadherins are a major class of cell surface receptors.

This study aims to assess the family functioning and health-related quality of life (HRQOL) in Chinese boys with Duchenne muscular dystrophy (DMD) and their parents using Pediatric Quality-of-Life Family Impact Module ( FIM) and Pediatric Quality-of-Life Inventory (PedsQL) 4.0. Findings from 15 families with DMD were compared with 15 unaffected families.

Organ-specific colonization suggests that specific cell-cell recognition is essential. Yet, very little is known about this particular interaction. Moreover, tumor cell lodgement requires binding under shear stress, but not static, conditions.

There is inconsistent evidence on the association between prenatal substance exposure and child behavioral problems. Children affected by maternal substance misuse are vulnerable to physical abuse and neglect. Few studies have examined factors contributing to internalizing and externalizing problems in these children.

Background: Smartphone-based psychoeducation interventions may be a low-cost, user-friendly alternative to resource-consuming, face-to-face antenatal classes to educate expectant mothers.

Objective: This study aimed to empirically examine whether such an intervention would lead to reduced postnatal depression, anxiety, or stress and result in a better health-related quality of life.

Methods: A single-blind randomized controlled trial was conducted in Hong Kong.

Previous studies point to a link between parenting style and child maltreatment, but evidence from a Chinese context is lacking. We investigated the association between parenting style and child maltreatment in Hong Kong, and examined whether family socio-economic status and child gender moderate this relationship. Using stratified random sampling, 7585 children in Grade 1 to Grade 3 of 51 schools in Hong Kong were recruited and their parents were invited to complete the questionnaire.

Background: Drug allergy, or drug hypersensitivity, is a potentially fatal disorder, and patients labeled with drug allergies have restricted access to first-line treatments. Full knowledge of the characteristics associated with drug allergies and severe reactions during allergy evaluation is beneficial for appropriate risk stratification.

Objective: We sought to determine whether certain clinical characteristics are associated with drug allergies in Chinese children.
