Behavioural and psychological symptoms of dementia (BPSD) are common in dementia. They cause significant distress to people with dementia and their carers. In managing BPSD, medical causes such as delirium must be excluded. Non pharmacological management, such as environmental and behavioural interventions are effective first line strategies. Medication may be useful in moderate to severe BPSD but must be used carefully in view of the risk of side-effects.

ObjectiveTo cultivate students innovative spirit and the ability of studying all their lives independently in the course of clinical transfusion laboratory medicine.MethodsBeginning with examination reform,we adopted the teaching mode,problem situation setting up-guidance to research and cooperation-evaluation of the students' learning effect by use of formative assessment.ResultsNew teaching mode acquired satisfactory results with development of students' activity and creativity.

ObjectiveTo investigate the influence of recombinant thioredoxin (TRX)on apoptosis of myocardium cell in viral myocarditis of mice.MethodsTwenty-four Balb/c mice,weighting 12 - 14 g,were randomly divided into 3 groups:the control group,the virus group and the protective group,8 mice in each group.The virus group and the protective group were injected with 0.1 ml 100TCID50 Coxackie virus B3 (CVB3)intraperitoneally,and the control group was injected equal volume of saline.Therewithal the protective group was injected with TRX(2 mg/kg) by tail vein,and the virus group was injected saline the same way.After 14 days all mice were killed and hearts were taken.Changes of myocardial histopathology was observed with optical microscope,cell apoptosis was checked by TUNEL technique,and the expression of apoptosis-related proteins (Bcl-2,caspase-3)in infiltrated cell of myocardium was determined by immunohistochemistry.Results(①)Lymphocyte infiltration and necrosis were observed in survivals of the virus group,sporadic coagulation necrosis and ballooning degeneration of cells were observed in the protective group,however no myocardial lesion was found in the control group.(②)TUNEL technique showed that the positive ratio of apoptosis in the virus group and the protective group[(90.23 ± 3.63)％,(20.02 ± 2.41)％] was significantly higher than that of the control group(0.00 ± 0.00,all P ＜ 0.05),the positive ratio of apoptosis in the protective group was significantly lower than that of the virus group (P ＜ 0.05 ).(③)Immunohistochemistry showed that the expression of protein Bcl-2(+,++,+++) in the virus group and the protective group was significantly higher than that of the control group (all P ＜ 0.05).The expression of protein Bcl-2 in the protective group was significantly higher than that of the virus group(P ＜ 0.05).The expression of caspase-3 (+,++) was significantly higher in the virus group and the protective group than the control group (all P ＜ 0.05).Compared with the virus group,the expression of caspase-3 in the protective group was significantly lower(P ＜ 0.05).ConclusionTRX could inhibit cardiomyocyte apoptosis in viral myocarditis mice and the inhibition is related to regulation of apoptosis-related protein expression.

INTRODUCTIONWeight-and-height-based anthropometric indices have long been used for obesity screening among adolescents.However, the ability of their age-and-sex-specific reference values in classifying adolescent as "obese" in different populations was not fully established. Our study aimed to validate the existing international (BMI-for-age charts from WHO, CDC, IOTF) and local cut-offs [percent weight for height (PWH)] for obesity against body fat percentage, as assessed by 4 skinfolds measurement.

MATERIALS AND METHODSA cross-sectional sample of 6991 adolescents aged 12 to 18 years was measured. All anthropometric measurements were compliant with the internationally accepted protocol. Obesity was defined as percentage body fat greater than or equal to 95 percentile, specific to age and sex. The validity of the existing classification criteria in detecting obesity was evaluated by comparing their respective diagnostic accuracy.

RESULTSBoth prevalence of obesity and diagnostic accuracy indices varied by the classification criteria. While all criteria generated very high specificity rates with the lowest being 95%, their sensitivity rates were low ranging from 43% to 71%. Youden's index suggested that CDC and WHO criteria had optimal sensitivity and specificity. ROC analysis showed that overall performance could be improved by refining the existing cut-offs.

CONCLUSIONSClinical validity of weight-and-height-based classification systems for obesity screening in Asian adolescents is poorer than expected, and this could be improved by refining the existing cut-offs.

INTRODUCTIONSingapore is the first Asian country to establish a nationwide breast screening programme, but our breast cancer screening uptake lags behind the Western countries. This survey focused on the subject of screening mammography, to assess the reasons for non-attendance and explore ways to improve our screening uptake.

MATERIALS AND METHODSFemales ≥21 years old were approached at primary healthcare clinics to participate in this survey, which questioned their knowledge, perception and expectations of breast screening.

RESULTSThere were 1011 respondents. Of the 740 respondents ≥40 years old, 332 respondents (45.5%) went for regular mammogram screening. Women who had lower household incomes [<$2000 (OR 0.49; 95% CI, 0.28 to 0.85); $2000 to $3999 (OR 0.59; 95% CI, 0.36 to 0.97)], did not know anyone with breast cancer (OR 0.62; 95% CI, 0.42 to 0.92), did not perform breast self-examination (OR 0.42; 95% CI, 0.28 to 0.62), had lower knowledge scores (OR 0.34; 95% CI 0.22 to 0.51), did not attend other health screening (OR 0.14; 95% CI, 0.05 to 0.41), and perceived mammography as embarrassing (OR 0.55; 95% CI, 0.31 to 0.96), were less likely to attend mammographic screening. Many did not know that screening is for the asymptomatic (51.2%), or the age to start screening (46.3%). Most respondents preferred to have their mammograms in the polyclinics (62.2%) and their screening reminders to be through short messaging service (SMS) (46.0%).

CONCLUSIONOur results show the current influences on Singapore women's screening practices, and also revealed that their understanding of mammogram screening is limited despite a high level of breast cancer awareness.

INTRODUCTIONMultidrug-resistant (MDR) Gram-negative healthcare-associated infections are prevalent in Singaporean hospitals. An accurate assessment of the socioeconomic impact of these infections is necessary in order to facilitate appropriate resource allocation, and to judge the costeffectiveness of targeted interventions.

MATERIALS AND METHODSA retrospective cohort study involving inpatients with healthcare-associated Gram-negative bacteraemia at 2 large Singaporean hospitals was conducted to determine the hospitalisation costs attributed to multidrug resistance, and to elucidate factors affecting the financial impact of these infections. Data were obtained from hospital administrative, clinical and financial records, and analysed using a multivariate linear regression model.

RESULTSThere were 525 survivors of healthcare-associated Gram-negative bacteraemia in the study cohort, with 224 MDR cases. MDR bacteraemia, concomitant skin and soft tissue infection, higher APACHE II score, ICU stay, and appropriate definitive antibiotic therapy were independently associated with higher total hospitalisation costs, whereas higher Charlson comorbidity index and concomitant urinary tract infection were associated with lower costs. The excess hospitalisation costs attributed to MDR infection was $8638.58. In the study cohort, on average, 62.3% of the excess cost attributed to MDR infection was paid for by government subvention.

CONCLUSIONMultidrug resistance in healthcare-associated Gram-negative bacteraemia is associated with higher financial costs--a significant proportion of which are subsidised by public funding in the form of governmental subvention. More active interventions aimed at controlling antimicrobial resistance are warranted, and the results of our study also provide possible benchmarks against which the cost-effectiveness of such interventions can be assessed.
