Design: Cross-sectional study.Setting: Cognition clinic and memory clinic of a public hospital in Hong Kong.Participants: A total of 272 participants (dementia, n=130; mild cognitive impairment, n=93; normal controls, n=49) aged 60 years or above were assessed using HK-MoCA. The HK-MoCA scores were validated against expert diagnosis according to the Diagnostic and Statistical Manual of Mental Disorders (4th ed) criteria for dementia and Petersen's criteria for mild cognitive impairment. Statistical analysis was performed using receiver operating characteristic curve and regression analyses. Additionally, comparison was made with the Cantonese version of Mini-Mental State Examination and Global Deterioration Scale. Results:The optimal cutoff score for the HK-MoCA to differentiate cognitive impaired persons (mild cognitive impairment and dementia) from normal controls was 21/22 after adjustment of education level, giving a sensitivity of 0.928, specificity of 0.735, and area under the curve of 0.920. Moreover, the cutoff to detect mild cognitive impairment was 21/22 with a sensitivity of 0.828, specificity of 0. • It is a reasonably good screening tool for mild cognitive impairment with comparable efficacy with the Cantonese version of Mini-Mental State Examination (MMSE). Implications for clinical practice or policy • HK-MoCA is brief and feasible to conduct in the clinical setting, and can be completed in less than 15 minutes.• HK-MoCA provides an attractive screening instrument in place of MMSE which has ceiling effect and needs to be purchased due to copyright issues.

This study examined the impact of attachment avoidance on relationship outcomes. A “cultural fit” hypothesis, which states that individual differences in personality should be associated with relationship problems if they encourage patterns of behavior that are incongruent with cultural norms, was investigated. It was hypothesized that attachment avoidance, a style of relationship in which emotional distance and independence are emphasized, would be more strongly associated with relationship problems in more collectivist societies (Hong Kong and Mexico) than in a more individualist one (the United States), given the greater emphasis placed on closeness and harmony in relationships in collectivist cultures. As predicted, associations between avoidant attachment and relationship problems were stronger in Hong Kong and Mexico than in the United States.

Objective To determine the value of early ultrasound examination for prenatal diagnosis of cardiac defects in chromosomally normal fetuses with increased nuchal translucency thickness at 10–14 weeks of gestation. Design Prospective audit. Setting Fetal Medicine Centre. Methods Specialist fetal echocardiography was carried out in 398 chromosomally normal fetuses with a nuchal translucency measurement above the 99th centile (2 3.5 mm). In the first 75 pregnancies the cardiac scan was carried out at 17–22 weeks and the next 323 cases had one scan at 13–17 weeks and another at 20–22 weeks. Pregnancy outcome was obtained in all of the cases. Results Major cardiac defects were present in 29 (7.3% of 398) cases and in 28 of these the diagnosis was made by antenatal echocardiography. In 27 of the 29 fetuses with major cardiac defects echocardiography was carried out at 13–17 weeks and an abnormality was suspected in 24 of the cases (88%). Conclusions Increased nuchal translucency in chromosomally normal fetuses is associated with an increased prevalence of major cardiac defects and, as such, is an indication for specialist fetal echocardiography. Most of the cardiac abnormalities are detectable on antenatal fetal echocardiography and many can be excluded by early scanning.

Cervical length is influenced by the degree of cervical curvature. The disparity of measurements between the internal and external os taken as a straight line or along the cervical canal increases with cervical length. However, this disparity may not have any clinical implications because at short cervical length (less than 16 mm) the cervix appears to be always straight.

BackgroundDementia caregiving is often associated with increase in depressive symptoms and strained relationships. This study tested whether telephone-delivered psychoeducation combined with an enhanced behavioral activation (BA) module had a better effect on the well-being of Alzheimer’s caregivers than psychoeducation alone. The focus is on enhancing the competent use of coping skills via BA. The program is delivered by telephone to increase accessibility and sustainability for caregivers. Senior citizens are trained as paraprofessionals to deliver the BA module to increase the potential for sustainability of the program.Methods and subjectsThe study compared two telephone interventions using a 4-month longitudinal randomized controlled trial. For the first 4 weeks, all participants received the same psychoeducation program via telephone. Then for the following 4 months, eight biweekly telephone follow-up calls were carried out. For these eight follow-up calls, participants were randomized into either one of the two following groups with different conditions. For the psychoeducation with BA (PsyED-BA) group, participants received eight biweekly sessions of BA practice focused on pleasant event scheduling and improving communications. For the psychoeducation only (PsyED only) group, participants received eight biweekly sessions of general discussion of psychoeducation and related information. A total of 62 family caregivers of persons living with dementia were recruited and 59 (29 in the PsyED-BA group and 30 in the PsyED only group) completed the whole study.ResultsAs compared to the group with psychoeducation and discussion, the group with enhanced BA had decreased levels of depressive symptoms. The study had a low attrition rate.ConclusionResults suggested that competence-based training could be effectively administered through the telephone with the help of senior citizens trained and engaged as paraprofessionals. Results contribute to the present literature by offering some framework for developing effective, accessible, sustainable, and less costly interventions.
