Characterization of a New HIV-1 CRF01_AE/B Recombinant Virus Form Among Men Who Have Sex with Men in Shanghai, China

Ou W, Li K, Feng Y, Huang Q, Ge Z, Sun J, et al.

AIDS Res Hum Retroviruses, 2019 04;35(4):414-418.
PMID: 30229664 DOI: 10.1089/AID.2018.0197

To date, there are 16 types of CRF01_AE/B circulating recombinant forms identified, and most of them are distributed in Asian countries such as China, Malaysia, and Singapore. Previous HIV molecular epidemiological surveys showed that CRF01_AE (27.6%) and B (9.6%) subtypes are predominant strains in mainland of China. At the same time, the HIV-1 virus spreads faster in the men who have sex with men (MSM) population than in other risk groups. In Shanghai district, ∼66.0% of newly reported cases were infected through homosexual transmission. In this study, we report a novel recombinant strain of CRF01_AE/B. The near full-length genome phylogenetic tree showed that the strain clustered with the CRF01_AE reference sequence and placed in the peripheral position within the branch of the CRF01_AE strain. Subregional evolutionary results indicated that the CRF01_AE subtype was derived from cluster 4 of CRF01_AE, which is mainly distributed in northern China. The subtype B was correlated with the U.S./Europe B, which are widely prevalent in the Chinese MSM population. In recent years, a large number of recombinant forms between CRF01_AE and B strains are continuously emerging in China. Therefore, understanding the current epidemic recombinant forms will have significant implications for prevention and treatment of HIV/AIDS.

Jeganathan VS, Sabanayagam C, Tai ES, Lee J, Sun C, Kawasaki R, et al.

Hypertens Res, 2009 Nov;32(11):975-82.
PMID: 19713968 DOI: 10.1038/hr.2009.130

Blood pressure has a significant effect on retinal arterioles. There are few data on whether this effect varies by race/ethnicity. We examined the relationship of blood pressure and retinal vascular caliber in a multi-ethnic Asian population. The study is population-based and cross sectional in design. A total of 3749 Chinese, Malay and Indian participants aged > or =24 years residing in Singapore were included in the study. Retinal vascular caliber was measured using a computer program from digital retinal photographs. The associations of retinal vascular caliber with blood pressure and hypertension in each racial/ethnic group were analyzed. The main outcome measures are retinal arteriolar caliber and venular caliber. The results show that retinal arterioles were narrower in persons with uncontrolled/untreated hypertension (140.0 microm) as compared with persons with controlled hypertension (142.1 microm, P=0.0001) and those with no hypertension (146.0 microm, P<0.0001). On controlling for age, gender, body mass index, lipids and smoking, each 10 mm Hg increase in mean arterial blood pressure was associated with a 3.1 microm decrease in arteriolar caliber (P<0.0001), with a similar magnitude seen in all three racial/ethnic groups: 3.1 microm in Chinese, 2.8 microm in Malays and 3.2 microm in Indians (P<0.0001 for all). Each 10 mm Hg increase in mean arterial blood pressure was associated with a 1.8 microm increase in venular caliber (P<0.0001); furthermore, the magnitude of this effect was similar across the three racial/ethnic groups. The effect of blood pressure on the retinal vasculature was similar across three major racial/ethnic groups in Asia.

Fulltext Anticardiolipin antibodies in patients from Malaysia with systemic lupus erythematosus

Jones HW, Ireland R, Senaldi G, Wang F, Khamashta M, Bellingham AJ, et al.

Ann Rheum Dis, 1991 Mar;50(3):173-5.
PMID: 2015010 DOI: 10.1136/ard.50.3.173

Systemic lupus erythematosus (SLE) is highly prevalent in Malaysia, which has a mixed population of Malays, Chinese, and Indians. A quantitative enzyme linked immunosorbent assay (ELISA) was used to determine anticardiolipin antibody (aCL) levels (total immunoglobulin, IgG, and IgM) in 200 patients with SLE (164 Chinese, 26 Malay, and 10 Indian) attending the University Hospital of Kuala Lumpur, Malaysia, and 103 matched controls. Only 33 (16.5%) of the patients had raised aCL levels; 26 had raised IgG aCL, five IgM aCL, and two both IgG and IgM aCL. There was a low prevalence of raised levels of aCL in the population studied, which was seen in conjunction with a rare occurrence of thrombosis. The classical association of high aCL levels with thrombocytopenia and recurrent abortions was noted, though not with cerebral disease. The low prevalence of aCL in this study population of mixed racial origin contrasts with findings in European patients with SLE and lends support to the influence of local factors, be they genetic or environmental, on the clinical manifestations of this disease.

Pharmacokinetics of propofol infusion in Asian patients undergoing coronary artery bypass grafting

Lee HS, Khoo YM, Chua BC, Ng AS, Tan SS, Chew SL

Ther Drug Monit, 1995 Aug;17(4):336-41.
PMID: 7482686

The pharmacokinetics of propofol was studied in 11 Asian patients with fentanyl-isoflurane anaesthesia during cardiopulmonary bypass (CPB) and undergoing elective coronary artery bypass grafting (CABG). Instead of the usual increments of morphine and a benzodiazepine, propofol (4 mg/kg/h) was initiated at the start of CPB and ceased at CPB separation. Whole blood propofol concentrations were determined during and postinfusion using high-performance liquid chromatography with fluorescence detection. Data from four patients seemed to fit a two-compartment model, whereas those from seven patients were significantly (F test, p < 0.05) better fitted to a three-compartment model. The pharmacokinetic parameters were as follows: The mean (SD) of the initial distribution phase t1/2 pi, intermediate distribution phase t1/2 alpha, and elimination phase t1/2 beta were 2.22 (1.04) min, 42.9 (16.4) min, and 370 (138) min, respectively. The mean clearance of 1.31 (0.50) L/min was lower than those reported from other studies, whereas the mean blood concentration of 2.2 (1.0) mg/L at the 1-h infusion period was higher. The mean calculated apparent Css was 3.9 (1.5) mg/L. The low clearance is likely to be due to hemodynamic changes during CPB and CABG, thereby affecting drug distribution and blood flow to the liver.

Fulltext Accommodation response to Chinese and Latin characters in Chinese-illiterate young adults

Radhakrishnan H, Hartwig A, Charman WN, Llorente L

Clin Exp Optom, 2015 Nov;98(6):527-34.
PMID: 26450168 DOI: 10.1111/cxo.12296

BACKGROUND: Differences in accommodation when reading Chinese, as compared to Latin, characters have been suggested to have a role in the higher prevalence of myopia in some Asian countries. Yeo and colleagues (Optom Vis Sci 2013; 90: 156-163) found that, in Chinese-literate children, accommodation was marginally more accurate (by less than 0.05 D), when reading Chinese text. This was attributed to the additional cognitive demand associated with interpreting the more complex Chinese symbols. The present study compared responses to single Chinese and Latin characters, while controlling for cognitive demand.
METHODS: The monocular accommodative response was measured in Chinese-illiterate adults (10 emmetropes, mean spherical equivalent: -0.07 ± 0.42 D, age: 29.9 ± 4.2 years; 11 myopes, mean spherical equivalent: -4.28 ± 2.84 D, age: 31.7 ± 4.6 years) with an open-field autorefractor. Four Chinese and three Latin characters (approximately 1.15 degrees subtense) were individually presented on a display screen one metre away from the subject, while their vergence was varied over the range zero to 5.00 D using spectacle trial lenses. The slope and the accommodative error index (AEI) were calculated from the accommodative stimulus/response curves (ASRC).
RESULTS: No statistically significant differences were found between refractive groups or among characters within the same refractive group in ARSC slopes (Latin: 0.87 ± 0.14 for myopes versus 0.81 ± 0.12 for emmetropes; Chinese: 0.84 ± 0.12 for myopes versus 0.85 ± 0.12 for emmetropes). No significant differences were found between characters in accommodative error index either (Latin, 0.78 ± 0.42 D for myopes versus 1.15 ± 0.72 D for emmetropes; Chinese, 0.74 ± 0.37 D for myopes versus 1.17 ± 0.83 D for emmetropes). However, accommodative error indices and accommodative errors were significantly higher for emmetropes.
CONCLUSION: Under controlled cognitive demand, Chinese and Latin characters elicited similar responses in both individual refractive groups. This study fails to support the hypothesis that development of myopia in some Asian populations is associated with larger lags of accommodation when reading or viewing Chinese characters.

Fulltext Uncovering Physical and Attitudinal Barriers to Adherence to Precautions for Preventing the Transmission of COVID-19 and Anxiety Level of People in Wuhan: 2 Months After the Lockdown

Lin Y, Alias H, Luo X, Hu Z, Wong LP

J Acad Consult Liaison Psychiatry, 2020 09 22;62(2):201-210.
PMID: 33183846 DOI: 10.1016/j.psym.2020.09.005

BACKGROUND: Wuhan, the epicenter of the coronavirus disease 2019 outbreak, was locked down on January 23, 2020. We aimed to investigate the barriers to the physical prevention, negative attitudes, and anxiety levels.
METHODS: A online cross-sectional survey was conducted with the people living in Wuhan between March 12th and 23rd, 2020.
RESULTS: Of a total of 2411 complete responses, the mean and standard deviation for the total physical prevention barriers score was 19.73 (standard deviation ± 5.3; range 12-45) out of a possible score of 48. Using a cut-off score of 44 for the State-Trait Inventory score, 79.9% (95% confidence interval [CI]: 78.2-81.5) of the participants reported moderate to severe anxiety during the early phase of the outbreak, and 51.3% (95% CI 49.2-53.3) reported moderate to severe anxiety after the peak of coronavirus disease 2019 was over (during the study period). Comparing anxiety levels in the early phase of the outbreak and after the peak of the outbreak, 58.5% (95% CI 56.5-60.5) recorded a decreased anxiety. Females reported a higher likelihood of having decreased levels of anxiety than males (odds ratio = 1.78, 95% CI 1.48-2.14). Low negative attitudes score were associated with a higher decrease in anxiety (odds ratio = 1.59, 95% CI 1.33-1.89).
CONCLUSIONS: The attitudinal barriers to prevention of transmission of coronavirus disease 2019 are more prominent than physical prevention barriers after the peak of coronavirus disease 2019. High anxiety levels even after the peak warrant serious attention.

Ching SM, Hassan F, Paimin F

Malaysian Journal of Medicine and Health Sciences, 2015;11(1):19-25.
MyJurnal

The National Clinical Practice Guideline in Tuberculosis (TB) was designed to improve the quality of tuberculosis care. However, it remains unknown whether primary care doctors adhere to it well. This audit aims to assess the quality of care in the process of TB contact tracing in a primary care setting. Methods: Data on TB contact tracing from 1st February 2013 to 15th February 2013 was obtained retrospectively from all medical records of diagnosed pulmonary TB in a public primary care clinic. All patients who fulfilled the inclusion and exclusion criteria were included in the study. Results: A total of 102 medical records of adult TB contacts were recruited. The median age of the TB contact was 34 (IQR=10) years and 65 % were male. Seventy two percent of the adult TB contact had a TBIS 10C3 form created, and 95% of the medical records were fully documented. History taking and physical examination were recorded on 97% and 99% of patients respectively during the first follow-up at the polyclinic. Eighty five percent and 100% of the patients had a chest-x-ray and sputum direct smear for acid-fast bacilli done respectively. The turn-up rate for the first, second, third and fourth visit was 100% to 32%, 10% and 2% respectively. Conclusion: The quality of care for adult TB contacts tracing in this clinical audit was found to be suboptimal. There is a difference between the current national guidelines and practice in the clinic. Certain measures to improve the quality of care for adult TB contact tracing
are urgently needed.

MyJurnal

Introduction: Diabetes Mellitus is a chronic disease and major cause of chronic renal disease. Chronic renal disease can be prevented if known risk factors were been early detected. Albuminuria is the earliest clinical evidence of chronic renal disease. Objectives of this study is to identify the incidence of albuminuria and relationship between albuminuria with socio demographic and clinical factors such as blood sugar control, blood pressure control, excessive body mass index and hypercholesterolemia.
Methodology: Data been collected from patient’s record that been regularly follow up at Primary Healthcare Clinics in Negeri Sembilan. Duration of study follow up was from the date of they been diagnosed of Diabetes Mellitus Type 2 until detection of albuminuria or 1st July 2007,end date of data collection then survival analysis been done.
Result: Majority of study population was female 60.9% and Malay 69.7%. Mean age was 59.9 ± 10.7 and duration having Diabetes Mellitus was 7.0 ± 6.3 years. Only 22% achieved optimum glucose (HbA1c < 6.5%), controlled blood preassure 130/80 mmHg 42.3%, level of cholesterol <4.5 mmol/L only 22.7 %, 11.4% of patients having ideal body weight < 23 kg/m2. The incidence of Diabetes Mellitus Type 2 was 24.4 cases per 1000 population. The median of follow up duration was 22 years; with minimum follow up was 7 months and maximum 42 years. Survival analysis showed that the median of free albuminuria among cases was 22 years (CI 95%:16.5 – 27.4). The log rank test showed no significant relationship between high blood pressure, excessive body mass index and hypercholesterolemia with albuminuria. This study noted that the occurrence of albuminuria seems to be higher among those were hypertensive (26.6%), and excessive body mass index (24.7%).
Conclusion: Percentage of Diabetes Mellitus Type 2 patient that achieved optimum clinical target still very low. Early detection of albuminuria is very important as preventive measure of diabetes nephropathy. Good blood pressure control and ideal body weight also prevent of occurring diabetes nephropathy complication.
Keywords: Diabetes Mellitus Type 2, albuminuria, survival analysis.

Effect of ethnicity on disease activity and physical function in psoriatic arthritis in a multiethnic Asian population

Leung YY, Fong W, Lui NL, Thumboo J

Clin Rheumatol, 2017 Jan;36(1):125-131.
PMID: 27796663 DOI: 10.1007/s10067-016-3460-1

Geographic differences in manifestation of psoriatic arthritis (PsA) could be related to differences in genetic or environmental factors. We aimed to compare the disease activity and functional status using validated outcome measures among patients with PsA of different ethnicities living in the same environment. We performed a cross-sectional study on consecutive patients with PsA classified by the Classification Criteria for Psoriatic Arthritis (CASPAR) criteria from a single center. Sociodemographic data, clinical variables, and patient-reported outcomes were collected using a standardized protocol. Disease activities were assessed by validated composite scores: clinical Disease Activity Index for Psoriatic Arthritis (cDAPSA), Composite Psoriatic Disease Activity Index (CPDAI), and minimal disease activity (MDA). Physical function was assessed with Health Assessment Questionnaire (HAQ) and the Medical Outcome Study Short-Form 36 (SF36) physical function subscales. Linear regression analyses were performed to identify variables associated with disease activities and physical function. Ninety-eight patients (51.5%, men) with mean (±SD) age and duration of PsA of 51.5 ± 13.8 and 5.5 ± 8.4 years were recruited. Indian was overrepresented compared with the national distribution of ethnicities. Compared to Chinese, Indian patients were more likely to be using biological therapies, have higher tender joint count, and worse enthesitis. Higher proportion of Indians had higher disease activity categories measured by cDAPSA, CPDAI, and MDA and had poorer physical function. In the multivariable analysis, ethnicity was significantly associated with HAQ and SF36-PF. Compared to Chinese, Indians with PsA living in the same environment had worse disease activity and physical function measured by validated outcomes.

Fulltext Molecular epidemiology demonstrates that imported and local strains circulated during the 2014 dengue outbreak in Guangzhou, China

Li G, Pan P, He Q, Kong X, Wu K, Zhang W, et al.

Virol Sin, 2017 Feb;32(1):63-72.
PMID: 28120220 DOI: 10.1007/s12250-016-3872-8

The dengue virus (DENV) is a vital global public health issue. The 2014 dengue epidemic in Guangzhou, China, caused approximately 40,000 cases of infection and five deaths. We carried out a comprehensive investigation aimed at identifying the transmission sources in this dengue epidemic. To analyze the phylogenetics of the 2014 dengue strains, the envelope (E) gene sequences from 17 viral strains isolated from 168 dengue patient serum samples were sequenced and a phylogenetic tree was reconstructed. All 17 strains were serotype I strains, including 8 genotype I and 9 genotype V strains. Additionally, 6 genotype I strains that were probably introduced to China from Thailand before 2009 were widely transmitted in the 2013 and 2014 epidemics, and they continued to circulate until 2015, with one affinis strain being found in Singapore. The other 2 genotype I strains were introduced from the Malaya Peninsula in 2014. The transmission source of the 9 genotype V strains was from Malaysia in 2014. DENVs of different serotypes and genotypes co-circulated in the 2014 dengue outbreak in Guangzhou. Moreover, not only had DENV been imported to Guangzhou, but it had also been gradually exported, as the viruses exhibited an enzootic transmission cycle in Guangzhou.

MyJurnal

Introduction: The incidence of diabetes mellitus (DM) is increasing globally and it is associated with significant morbidity and mortality. The importance of a better quality of diabetes care is increasingly acknowledged. Objective: This clinical audit was conducted to assess the quality of care given to type 2 DM patients in public primary care clinics. Methods: A clinical audit was conducted in two selected urban public primary care clinics, between April and June of 2005. The indicators and criteria of quality care were based on the current Malaysian clinical practice guidelines for type 2 DM. A structured pro forma was used to collect data. Results: A total of 396 medical records of patients with type 2 DM were included in this audit. Most of the patients had measurements of fasting blood glucose and blood pressure recorded in more than 90% of the visits over the previous one year. Twenty-seven percent of the patients had glycosylated haemoglobin (HbA1c) done every 6 months with a mean of 8.3%. Only 15.6% had HbA1c values less than 6.5 %. Fifty percent had blood pressure controlled at 130/80 mmHg and below; and 13.0% had low density lipoprotein cholesterol values of 2.6 mmol/L or less. The majority of the patients were overweight or obese. Conclusions: The quality of diabetes care in this study was
found to be suboptimal. There is a gap between guidelines and clinical practice. Certain measures to improve the quality of diabetes care need to be implemented with more rigour.

Attendance at a child health clinic in Malaysia

Chen PC

J Trop Med Hyg, 1975 Jan;78(1):6-12.
PMID: 1121041

One hundred and ninety-nine children brought by 181 adults to a child health clinic based in a rural health sub-centre in Peninsular Malaysia are studied. It is noted that the families from which they come are relatively poor, with a large number of children, and that they are fairly highly motivated. Forty-four per cent of children attending the clinic at the time of the study are symptomatic indicating the need to organise the child health clinic on a "preventive-curative" basis. It is also noted that the young child is initially seen in early infancy but is lost to the clinic when he is older making it judicious to formulate immunization schedules that take this into account.

Prevalence of diabetes is escalating both globally as well as in Malaysia. With the epidemic of diabetes and its related morbidities and mortalities, health care professionals are facing an unprecedented challenges in controlling the disease. Objective: To determine the metabolic control and the cardiovascular risk factors among type 2 diabetic patients in a primary care setting. Method: This was a cross sectional study conducted in a primary care clinic in Selangor, Malaysia. Inclusion criteria were all type 2 diabetic patients aged 18 and above and were being followed-up for more than six months prior to the recruiting period in May 2009. The demographic data were obtained through face- to-face interview. Height, weight and blood pressure of the patients were taken during the day of data collection. The co-morbidities and laboratory results were obtained from the medical records. Results: Two-hundred patients were recruited. The mean age was 58.6 (SD=10.5) with 79.0% of the patients aged more than 50 years old. The majority of the patients were female (62.5%). One-tenth (11.5%) were smokers. More than half of the patients (64.0%) had co-morbid of hypertension and half of them (50.5%) had dyslipidaemia. A total of 72.5% of the patients had 3 or more cardiovascular risk factors. Less than one fifth of the patients had achieved the target of control for glycaemia, blood pressure, LDL and BMI. Those age 60 and above had significantly higher proportion of patients achieving fasting blood glucose control (p=0.033). Conclusion: The majority of type 2 diabetic patients had multiple cardiovascular risk factors (3 or more risk factors) and had not achieved the recommended goals in
metabolic control.

Fulltext Knowledge, attitude and practice on breastfeeding in Klang, Malaysia

Tan KL

International Medical Journal Malaysia, 2009;8(1):17-21.
MyJurnal

Introduction: In Klang, a district in the state of Selangor in Peninsular Malaysia, the effects of westernization and urbanization in recent years have had an impact on infant feeding. The objective of this study was to evaluate the practice, knowledge and attitude to breastfeeding and to assess factors associated with breastfeeding among women in Klang, Malaysia. Materials and Methods: A cross-sectional study was carried out between June and October 2006 involving 220 women with infants aged six months from two randomly selected health clinics were selected and interviewed. Data on socio-demographic, infant factors, infant feeding in the first six months of life, knowledge and attitude towards breastfeeding were collected. Results: Exclusive breastfeeding was reported by 32.8%, mixed feeding was reported by 14.5% and infant formula feeding was reported by 52.7% of the respondents. Chinese women were more likely not to practice exclusive breastfeeding compared to Malay women (odds ratio 18.27, 95% CI: 3.95, 84.54) while working women were more likely not to practice exclusive breastfeeding compared to non working women (odds ratio 3.75, 95% CI: 1.64 , 8.55). Positive association with not exclusive breastfeeding included women with high household income and women with male infants. Malaysian women had a positive attitude but work place and short maternity leave had a negative impact on breastfeeding. Conclusion: Women of Chinese ethnicity, working, from high family income and with male infants were less likely to exclusively breastfeed. Adopting facilitatory measures at hospitals and work place could increase the rate of exclusive breastfeeding.

Armstrong RW, Kutty MK, Dharmalingam SK

Br. J. Cancer, 1974 Jul;30(1):86-94.
PMID: 4413823

A "registry" of all known cases of nasopharyngeal carcinoma in Malaysia, 1968-72, was established. Attention was focused on the State of Selangor where conditions are best for case finding. Age-adjusted incidence rates among Chinese males and females were 17·3 and 7·3 per 100,000; among Malay males and females, the rates were 2·5 and 0·3 and among Indian males, 1·1. The detailed ethnicity of 192 cases in Selangor was established. Estimated incidence rates for the Chinese sub-groups agreed with the pattern observed elsewhere: highest among the Cantonese, lowest among the Hokkien/Teochiu, with the Khek in between. There was no correlation between histological type and sub-ethnic group among the Chinese cases.

Validation of the Chinese version of public attitudes toward epilepsy scale in Mainland China

Yue Z, Ma C, Lim KS, Xiao B, Wu Q, Shu Y, et al.

Epilepsy Behav, 2017 07;72:150-155.
PMID: 28582727 DOI: 10.1016/j.yebeh.2017.04.028

PURPOSE: Epilepsy is a significant yet seriously underappreciated public health issue in Mainland China. The stigma and discrimination toward people with epilepsy (PWE) and their families are especially severe in China based on cultural misconceptions which cause tremendous psychological, economic and social burdens. It is imperative to formulate a targeted public intervention to eliminate knowledge gaps and correct these misconceptions of epilepsy. However, to date, the essential tools that may drive such an intervention by measuring the public perspective on PWEs is lacking in China. The goal of this study is to test the reliability and validity of a Simplified Chinese version of the "Public Attitude Toward Epilepsy" scale (PATE) in Mainland China which can be used to understand the content and identify the possible sources of stigma to better inform the design and focus of future stigma reduction interventions.

METHODS: The standard procedure of cross-cultural adaptation was used in the translation process. Subjects from different economic and social backgrounds were enrolled by convenience sampling in central China. Exploratory factor analysis and confirmatory factor analysis were used to check the underlying factor structure of the items. Furthermore, Cronbach's alpha was utilized to assess internal consistency.

RESULTS: 199 respondents were included in the final analysis. Content validity of this Chinese PATE was assessed to be adequate for assessing public attitudes toward epilepsy among the mainland Chinese. Two factors were extracted from the data by exploratory factor analysis; confirmatory factor analysis further confirmed good consistency of theoretical constructs between the original Public Attitudes Toward Epilepsy scale and our Chinese PATE. Our Chinese PATE presented excellent internal consistency (α=0.853-0.909).

CONCLUSION: This version of the Chinese PATE showed acceptable psychometric properties, indicating that it can be implemented in surveying public attitudes toward epilepsy in Mainland China.
