How people of African Caribbean or Irish ethnicity cope with long-term health conditions in UK community settings: A systematic review of qualitative,quantitative and mixed method studies

Living with a chronic or mental health condition can be challenging and requires considerable adjustment. As ways of coping are culturally influenced, it is important to understand how minority ethnic populations cope, to inform appropriate services. This review aimed to explore the coping strategies used by UK residents from an African Caribbean or Irish background between 1960 and 2020. A systematic literature search on strategies used to cope with chronic health conditions in both populations living in the United Kingdom identified 26 relevant studies. Data were extracted, quality of papers was appraised and critical interpretive synthesis was applied. Two major foci of the studies were coping strategies and barriers to coping. The main coping strategies were denial/scepticism, self-management, spirituality and religion. Within each population, there was variation in ways of coping. The review highlights the complex role of religion in influencing coping strategies. It demonstrates how personal and minority ethnic populations’ experiences of service use are connected with stigma, fear and mistrust, which also act as barriers to seeking help and to coping. Coping with a chronic or mental health condition in the Irish and African Caribbean populations is under-researched. Stigma, fear and mistrust in services act as key barriers to help-seeking and religion is a prominent coping strategy. However, few detailed examples were given on how it was used to assist individuals when managing a chronic or mental health condition. Also due to a lack of research, firm conclusions cannot be drawn for the Irish population.     

Fear and anxiety about COVID-19 among local and overseas Chinese university students

This study aimed to establish a new COVID-19 Fear (Higher Education) scale to investigate the relationship between fear and generalised anxiety symptoms among Chinese students in mainland China, Hong Kong, and other countries. 219 Chinese university students studying in universities in mainland China (n = 76, 34.7%), Hong Kong (n = 66, 30.1%), and overseas (i.e., outside of China as international students, n = 77, 35.2%) participated in an online study from March 31, 2020 to April 4. Participants completed a newly developed COVID-19 Fear (Higher Education) scale to measure three domains of fear including fear of infection, fear of instability and fear of insecurity related to the COVID-19 pandemic. They also completed the Generalized Anxiety Disorder 7-item scale (GAD-7) on the severity of anxiety symptoms. About 9.6% of the participants could be classified as exhibiting high anxiety level according to the GAD-7. More students studying overseas (about 15%) were classified into the high GAD group when compared to students studying in both mainland China (6.6%) and Hong Kong (6.1%). MANOVA results showed that students studying in Hong Kong and overseas had more concerns related to preventive measures related to COVID-19 than their mainland counterparts did. We concluded that international students studying away from their home country would have higher risk to develop anxiety problems during a collective trauma such as the COVID-19 pandemic. Education institutions should provide support services including online support groups, social media groups for mutual support to alleviate the fear and anxiety of international students.     

精神分裂症氯氮平治疗前后中枢单胺递质含量的对比研究

目的 :观察氯氮平治疗精神分裂症对中枢单胺递质系统的影响。方法 :应用高效液相色谱测定 2 8例精神分裂症氯氮平治疗前后脑脊液NE、DA、5 -HT、MAPG、HVA、5 -HIAA的含量。结果 :治疗前后脑脊液中单胺神经递质及其代谢产物差异无显著性 ;应用中枢神经递质代谢产物MHPG/HVA、5 -HIAA/HVA、MHPG/ 5 -HIAA的比值作为两个中枢递质系统之间相互作用的功能态 ,发现精神分裂症治疗前MGPG/MVA明显低于治疗后 (P <0 .0 5 )。结论 :精神分裂症治疗前与治疗后相比 ,DA功能相对亢盛 ,NE功能相对低下 ,氯氮平可能是通过调整NE -DA系统的功能态而发挥治疗作用。

An Inter- and Intra-University Comparison With Short Case-Based Testing

Comparisons between PBL and non-PBL medical schools on problem-solving ability often show no differences. This could be either due to the fact that no difference in problem-solving skills exists or that the instruments used are inadequate. In this study a key-feature approach case-based examination was used to compare two medical schools in the Netherlands, one of which has a PBL curriculum (Maastricht) and one which has a program half way a transition from a non-PBL towards a PBL curriculum (Groningen). Differences were found both in proficiency scores and in the pattern of response times, both supporting the assumption that a PBL approach would lead to a higher level of problem solving ability. The effect size, however, is not as large as originally assumed by the PBL proponents. Conclusions must be drawn with caution, but it seems likely that a test based on large numbers of short cases is the most sensitive in detecting differences in problem solving ability between students of different curricula.

Anticoagulation after valve replacement: a multicenter retrospective study

Anticoagulant therapy after cardiac valve replacement was evaluated retrospectively in 1,200 patients attending 8 cardiac surgery clinics in the Tokyo area as part of the Tokyo Area Study on Anticoagulation After Cardiac Valve Replacement Using PT-INR (TAS). A prospective trial is also in progress and will be reported later. The prothrombin time international normalized ratio (PT-INR) was determined at the time of thromboembolic and bleeding complications in 1,200 patients. During the 5 year study period, thromboembolisms occurred in 21 patients, and bleeding complications occurred in 15 patients. In 71% of patients with thromboembolism and 47% of those with bleeding complications, the PT-INR was within the range of 1.6 to 2.8, which is the accepted therapeutic range in Japan. Therefore, the correct PT-INR therapeutic range for Japanese patients with mechanical heart valves needs to be reexamined, and data from the prospective TAS trial that is currently underway will be used for this purpose.     

A Kiswahili version of the SF-36 Health Survey for use in Tanzania: translation and tests of scaling assumptions

The objective of the study was to translate and adapt the SF-36 Health Survey for use in Tanzania and to test the psychometric properties of the Kiswahili SF-36. A cross-sectional study was conducted as part of a household survey of a representative sample of the adult population of Dar es Salaam, Tanzania. The IQOLA method of forward and backward translation was used to translate the SF-36 into Kiswahili. The translated questionnaire was administered by trained interviewers to 3,802 adults (50% women, mean (SD) age 31 (13) years, 50% married and 60% with primary education). Data quality and psychometric assumptions underlying the scoring of the eight SF-36 scales were evaluated for the entire sample and separately for the least educated subgroup (n=402), using multitrait scaling analysis. Forward and backward translation procedures resulted in a Kiswahili SF-36 that was considered conceptually equivalent to the US English SF-36. Data quality was excellent: only 1.2% of respondents were excluded because they answered less than half of the items for one or more scales; ninety percent of respondents answered mutually exclusive items consistently. Median item–scale correlations across the eight scales ranged from 0.47 to 0.81 for the entire sample. Median scaling success rates were 100% (range 87.5–100.0). The median internal consistency reliability of the eight scales for the entire sample was 0.81 (range 0.70–0.92). Floor effects were low and ceiling effects were high on five of the eight scales. Results for n=402 people without formal education did not differ substantially from those of the entire sample. The results of data quality and psychometric tests support the scoring of the eight scales using standard scoring algorithms. The Kiswahili translation of the SF-36 may be useful in estimating the health of people in Dar es Salaam. Evidence for the validity of the SF-36 for use in Tanzania needs to be accumulated.     

Behavioural and School Adjustment of 12–13-year old Internationally Adopted Children in Norway: a Research Note

Rutter's scales for parents and teachers were used to assess the behavioural and emotional adjustment of 151 12-13-year old internationally adopted children. Additional questions about school adjustment were added to the teachers' questionnaire. The majority of the adopted children were found to be well adjusted. However, the adopted children were given higher mean scores both for the full scale and on a "hyperactive" subscale than a comparison group of non-adopted children. More adopted than non-adopted children had problems with arithmetic. Adopted boys had higher mean scores than adopted girls on both Rutter scales. Age at adoption was unrelated to outcome.
