Mothers’ health-related quality of life: Its relationship with children’s health-related quality of life and behavior in low-income families

Objective: To examine the association between mothers’ health-related quality of life (HRQOL) and their children’s HRQOL and behavior in low-income families. Methods: Mothers of 278 children aged 6‐12 years from low-income families were invited to complete the Child Health Questionnaire Parent Form 50 (CHQ-PF50) and the Strength and Difficulties Questionnaire (SDQ) for their children as well as the 12-item Short-Form Health Survey version 2 (SF-12v2) and the Patient Health Questionnaire-2 (PHQ-2). Multiple linear regressions with mother‐child pairs as the unit of analysis were performed to examine the associations between maternal and child variables with adjustment of mother- and child-level confounders. Results: Compared with the general population, low-income mothers had a lower mean SF-12v2 mental component summary score and their children also had lower mean CHQ-PF50 physical and psychosocial summary scores and SDQ total difficulties score. Children of mothers with SF-12v2 scores below the population mean of 50 had significantly worse CHQ-PF50 scores and higher SDQ total difficulties scores. The mother’s PHQ-2 depression status had no association with the child’s CHQ-PF50 scores. Conclusion: Our findings suggest that more attention should be paid to reducing the negative impact of health problems on mothers’ daily roles in childcare in low-income families.published_or_final_versio

Hope-based intervention for individuals susceptible to colorectal cancer: a pilot study

Individuals undergoing genetic testing for hereditary colorectal cancer (HCRC) are prone to develop psychological problems. This study investigated the short-term efficacy of a hope-based intervention program in increasing hope levels and decreasing psychopathology among HCRC genetic testing recipients. A longitudinal study was carried out on HCRC genetic testing recipients recruited by the Hereditary Gastrointestinal Cancer Registry. Participants joined a hope-based intervention program consisting of six sessions of weekly closed group therapy. Psychological questionnaires were administered immediately before the first and after the last sessions of the program measuring hope, anxiety and depression levels of the participants. There were 22 participants (7 men and 15 women) at a mean age of 49.4 ± 9.6 years. Women tended to have higher level of anxiety than men at pre-intervention. Paired sample t tests were conducted. Hope levels increased significantly from pre- to post-intervention (pre-total hope score = 5.56; post-total hope score = 6.07; t(1) = -0.281, p < 0.05). Anxiety level also decreased significantly from pre- to post-intervention (pre-anxiety score = 7.38; post-anxiety score = 5.90; t (1) = 2.35, p < 0.05). Our findings imply that hope-based intervention program would be effective in enhancing hope in HCRC genetic testing recipients. The program may also be more effective in alleviating anxiety than depression in these individuals. © 2012 The Author(s).published_or_final_versio

Linking cohort-based data with electronic health records: a proof-of-concept methodological study in Hong Kong.

OBJECTIVES: Data linkage of cohort-based data and electronic health records (EHRs) has been practised in many countries, but in Hong Kong there is still a lack of such research. To expand the use of multisource data, we aimed to identify a feasible way of linking two cohorts with EHRs in Hong Kong. METHODS: Participants in the 'Children of 1997' birth cohort and the Chinese Early Development Instrument (CEDI) cohort were separated into several batches. The Hong Kong Identity Card Numbers (HKIDs) of each batch were then uploaded to the Hong Kong Clinical Data Analysis and Reporting System (CDARS) to retrieve EHRs. Within the same batch, each participant has a unique combination of date of birth and sex which can then be used for exact matching, as no HKID will be returned from CDARS. Raw data collected for the two cohorts were checked for the mismatched cases. After the matching, we conducted a simple descriptive analysis of attention deficit hyperactivity disorder (ADHD) information collected in the CEDI cohort via the Strengths and Weaknesses of ADHD Symptoms and Normal Behaviour Scale (SWAN) and EHRs. RESULTS: In total, 3473 and 910 HKIDs in the birth cohort and CEDI cohort were separated into 44 and 5 batches, respectively, and then submitted to the CDARS, with 100% and 97% being valid HKIDs respectively. The match rates were confirmed to be 100% and 99.75% after checking the cohort data. From our illustration using the ADHD information in the CEDI cohort, 36 (4.47%) individuals had ADHD-Combined score over the clinical cut-off in the SWAN survey, and 68 (8.31%) individuals had ADHD records in EHRs. CONCLUSIONS: Using date of birth and sex as identifiable variables, we were able to link the cohort data and EHRs with high match rates. This method will assist in the generation of databases for future multidisciplinary research using both cohort data and EHRs

A prospective cohort study to investigate parental stress and child health in low-income Chinese families: protocol paper

Introduction Chronic stress has adverse effects on health. Adults and children from low-income families are subject to multiple sources of stress. Existing literature about economic hardship mostly focuses on either adults or children but not both. Moreover, there is limited knowledge on the relationship between parental generalised stress and child health problems. This study aims to explore the bidirectional relationship between parental stress and child health in Chinese low-income families and to identify other modifiable factors influencing this relationship. Methods and analysis This prospective cohort study will sample 254 low-income parent–child pairs and follow them up for 24 months with assessments at three time points (baseline, 12 and 24 months) on parental stress, health-related quality of life (HRQOL) and child health and behaviour using both subjective measures and objective physiological parameters. This study will collect data using standardised measures on HRQOL and behaviours of children as well as on HRQOL, mental health and stress levels of parents along with physiological tests of allostatic load and telomere length. The mediating or moderating effect of family harmony, parenting style and neighbourhood conditions will also be assessed. Data will be analysed using latent growth modelling and cross-lagged path analysis modelling to examine the bidirectional effect of parental stress and child health over time. Mediation and moderation analysis will also be conducted to examine the mechanism by which the variables relate. Ethics and dissemination This study was approved by the institutional review board of the University of Hong Kong—the Hospital Authority Hong Kong West Cluster, reference no: UW 16-415. The study findings will be disseminated through peer-reviewed publications and international conferences.published_or_final_versio

Polo kinase recruitment via the constitutive centromere-associated network at the kinetochore elevates centromeric RNA

The kinetochore, a multi-protein complex assembled on centromeres, is essential to segregate chromosomes during cell division. Deficiencies in kinetochore function can lead to chromosomal instability and aneuploidy-a hallmark of cancer cells. Kinetochore function is controlled by recruitment of regulatory proteins, many of which have been documented, however their function often remains uncharacterized and many are yet to be identified. To identify candidates of kinetochore regulation we used a proteome-wide protein association strategy in budding yeast and detected many proteins that are involved in post-translational modifications such as kinases, phosphatases and histone modifiers. We focused on the Polo-like kinase, Cdc5, and interrogated which cellular components were sensitive to constitutive Cdc5 localization. The kinetochore is particularly sensitive to constitutive Cdc5 kinase activity. Targeting Cdc5 to different kinetochore subcomplexes produced diverse phenotypes, consistent with multiple distinct functions at the kinetochore. We show that targeting Cdc5 to the inner kinetochore, the constitutive centromere-associated network (CCAN), increases the levels of centromeric RNA via an SPT4 dependent mechanism
