In the absence of a mandatory reporting (MR) structure, it is unclear how nurses perceive or exercise their role in child protection. This study examined knowledge and perceptions of child protection and MR among nurses working in Hong Kong. This cross-sectional web-based survey used the Child Abuse Report Intention Scale to measure nurses' child protection knowledge and attitudes, and their perceived norms, control, and intention to report suspected maltreatment. Nurses also indicated if they support MR and to provide an explanation for their preference. Quantitative data were described and analyzed using bivariate and regression analyses. Open-ended responses were analyzed using directed content analysis. A convenient sample of 91 nurses working in Hong Kong completed the survey. The majority (86%) were female with a mean of 9.5 years of nursing experience; their mean knowledge score was 6.64 out of 13 (range 2–10). Compared with other maltreatment types, sexual abuse was perceived to be most severe and most likely to be reported. Perceived severity and attitudes toward child maltreatment was significantly associated with nurses' intention to report. Over half (58%) supported MR; those against MR expressed concerns about lack of support from management. Although nurses working in Hong Kong still hold polarized views about MR, findings point to the importance of creating a supportive reporting culture, and designing training programs that focus on changing perceptions about child protection in order to improve their tendency to report.

Public housing estate is a key determinant of community health risk in American/European cities. However, how forms/characteristics of compact/hilly public housing's neighbourhoods affect dementia among Asian seniors was underestimated. This was a cross-sectional study. A total of 2,077 seniors living in Hong Kong's public housing estates were included. Dementia was measured by a Cantonese version of Montreal – Cognitive Assessment. Built environment was measured based on three dimensions (greenery, walkability, accessibility), including 11 metrics. Circular buffers (without walking paths) and service areas (considering walking paths) with two-dimensional/three-dimensional (terrain) adjustment were applied to quantify forms/characteristics of neighbourhoods. Two spatial buffers were applied: immediate distance (200 m) and walkable distance (500 m). Exposure-by-exposure regressions were applied to evaluate the associations between form/characteristics of neighbourhood and dementia. Forms/characteristics without considering walking paths may overestimate health benefits from built environment. For circular buffers, higher percentage of building coverage, higher land use mix and more community/transportation/leisure facilities were negatively associated with dementia. All measures of greenery were positively associated with dementia. For service areas, measures of walkability and accessibility became insignificant except more community facilities at the immediate distance. Furthermore, terrain effect was insignificant when it was compared with the impacts of walking paths. Dementia among seniors in hilly public housing estates was negatively associated with neighbourhood's walkability and accessibility and was influenced by walking paths. For healthy ageing, improved forms/characteristics of public housing neighbourhoods should include more accessible spaces and community facilities along walking paths for physical activities and basic daily needs.

Objectives:Lithium has recently been found to enhance neuronal regeneration and differentiation. This arouses its potential use to treat spinal cord injury patients. The safety and pharmacokinetics of lithium are not verified for this group of patients as their internal organ functions may change. This is a phase 1 clinical trial to evaluate the safety and pharmacokinetics of lithium in spinal cord injury patients.Methods:A total of 20 chronic spinal cord injury subjects were recruited. Oral lithium carbonate was given in divided dose to maintain the serum lithium level 0.6-1.2 mmol l−1 for 6 weeks. Safety parameters, adverse events and pharmacokinetic data were carefully collected and monitored.Results:No severe adverse event was documented. All blood parameters remained stable. Nausea and vomiting were the most common complaints but tolerance was improved in 2 weeks for most subjects. A wide range of oral doses was required to maintain serum lithium level at the targeted range. However, the dose for individual subject was relatively constant.Conclusion:This phase 1 clinical trial is the first report indicating the safety of lithium in chronic spinal cord injury patients. It is well tolerated after the first 2 weeks. Individual titration of lithium is essential to maintain an optimal serum lithium level but once the desirable level is achieved, the oral dose remains relatively unchanged for maintenance.

Worldwide, the incidence of motor neuron disease (MND) has been increasing steadily over recent decades. We reported a follow‐up epidemiology study of MND in this locality. We identified the subjects from the computer database of the government hospital system between 1 January 1997 and 31 January.2002 by searching the ICD code starting from 335.xx. Every retrieved case or their records were reviewed and validated by neurologist(s) of the responsible regional hospitals which the patients attended. One hundred and twenty cases from seven regional hospitals (serving 48.05% of the HKSAR population) were identified, validated and confirmed to be MND or related diseases. Ninety‐eight new cases were diagnosed during the study period. Average age of onset was 58.76 years; SD 14.12 (28–89) years. Male to female ratio was 1.72:1. Peak age of onset was 60–64 years without sex difference. The adjusted incidence rate was 0.60/100,000/year. The adjusted point prevalence at the prevalence date (31 January 2001) was 3.04/100,000. Despite the incidence and prevalence of MND among Hong Kong Chinese, it remained low compared to worldwide figures, and our data suggested a significant rise of MND or related disease in the last decade. A territory‐wide prospective epidemiological study is indicated. [ABSTRACT FROM AUTHOR]
