| 1 | A community-based prospective cohort study of dengue viral infection in Malaysia: the study protocol显示文摘Background:Globally,dengue infections constitute a significant public health burden.In recent decades,Malaysia has become a dengue hyper-endemic country with the co-circulation of the four dengue virus serotypes.The cyclical dominance of sub-types contributes to a pattern of major outbreaks.The consequences can be observed in the rising incidence of reported dengue cases and dengue related deaths.Understanding the complex interaction of the dengue virus,its human hosts and the mosquito vectors at the community level may help develop strategies for addressing the problem.Methods:A prospective cohort study will be conducted in Segamat district of Johor State in Peninsular Malaysia.Researchers received approval from the Malaysian Medical Research Ethics Committee and Monash University Human Research Ethics Committee.The study will be conducted at a Malaysian based health and demographic surveillance site over a 1 year period in three different settings(urban,semi-urban and rural).The study will recruit healthy adults(male and female)aged 18 years and over,from three ethnic groups(Malay,Chinese and Indian).The sample size calculated using the Fleiss method with continuity correction is 333.Sero-surveillance of participants will be undertaken to identify asymptomatic,otherwise healthy cases;cases with dengue fever who are managed as out-patients;and cases with dengue fever admitted to a hospital.A genetic analysis of the participants will be undertaken to determine whether there is a relationship between genetic predisposition and disease severity.A detailed medical history,past history of dengue infection,vaccination history against other flaviviruses such as Japanese encephalitis and Yellow fever,and the family history of dengue infection will also be collected.In addition,a mosquito surveillance will be carried out simultaneously in recruitment areas to determine the molecular taxonomy of circulating vectors.Discussion:The research findings will estimate the burden of asymptomatic and symptomatic dengue at the community level.It will also examine the relationship between virus serotypes and host genotypes,and the association of the clinical manifestation of the early phase with the entire course of illness. | Nowrozy Kamar Jahan Mohtar Pungut Ahmad Amreeta Dhanoa Cheong Yuet Meng Lau Wee Ming Daniel D.Reidpath Pascale Allotey Anuar Zaini Maude Elvira Phipps Quek Kia Fatt Aman Bin Rabu Rowther Sirajudeen Ahmad AbdulBasitz Ahmad Fatan Faidzal Adlee Ghafar Hamdan Bin Ahmad Iekhsan Othman Sharifah SyedHassan | 2016 | Infectious Diseases of Poverty2016，5，1： | 1 |

| 7 | 在没有输血的血红素 2 g/dL 的成功的肠外科显示文摘 We were unable to find reports in the published medical literature of any cases of bowel surgery being successfully performed at such a low hemoglobin level,without blood transfusion or blood products pre or post-surgery,with the patient’s uncomplicated recovery.This study is about such a case.A patient presenting with severegastrointestinal bleeding was diagnosed with enteric fever and multiple ileal ulcers.He had an extremely low hemoglobin level(2 g/dL) and mild renal and hepatic impairment.He was immediately admitted for right hemicolectomy under general anesthesia though he refused transfusion of blood or blood products prior to,during,or after surgery on religious grounds(Jehovah’ s Witnesses).After the surgery and having survived these potentially life-threatening circumstances,he left the hospital without major complications.In such circumstances,lives may be saved by prompt clinical decision-making,collaboration and swift surgical intervention coupled with the immediate consultation and input of the patient and family. | Ramakrishnapillai Padmakumar Madhukara Pai Shams Farish Jayadevan Rajeev Thampi Sanjeev Thekke Veetil Sreevalsan Binu Sheetal Yesudas Santhakumari Sooraj Shamna Safar Rowther | 2013 | World Journal of Gastrointestinal Surgery2013，5，8： | 0 |
| 8 | Seroprevalence of dengue among healthy adults in a rural community in Southern Malaysia:a pilot study显示文摘Background:The frequency and magnitude of dengue epidemics continue to increase exponentially in Malaysia,with a shift in the age range predominance toward adults and an expansion to rural areas.Despite this,information pertaining to the extent of transmission of dengue virus(DENV)in the rural community is lacking.This communitybased pilot study was conducted to establish DENV seroprevalence amongst healthy adults in a rural district in Southern Malaysia,and to identify influencing factors.Methods:In this study undertaken between April and May 2015,a total of 277 adult participants were recruited from households across three localities in the Sungai Segamat subdistrict in Segamat district.Sera were tested for immunoglobulin G(IgG)(Panbio®Dengue Indirect IgG ELISA/high-titer capture)and immunoglobulin M(IgM)(Panbio®)antibodies.The plaque reduction neutralization test(PRNT)was conducted on random samples of IgGpositive sera for further confirmation.Medical history and a recall of previous history of dengue were collected through interviews,whereas sociodemographic information was obtained from an existing database.Results:The overall seroprevalence for DENV infection was 86.6%(240/277)(95%CI:83-91%).Serological evidence of recent infection(IgM/high-titer capture IgG)was noted in 11.2%(31/277)of participants,whereas there was evidence of past infection in 75.5%(209/277)of participants(indirect IgG minus recent infections).The PRNT assay showed that the detected antibodies were indeed specific to DENV.The multivariate analysis showed that the older age group was significantly associated with past DENV infections.Seropositivity increased with age;48.5%in the age group of<25 years to more than 85%in age group of>45 years(P<0.001).No associations with occupation,study site,housing type,comorbidity,educational level,and marital status were observed,although the latter two were statistically significant in the univariate analysis.None of the studied factors were significantly associated with recent DENV infections in the multivariate analysis,although there was a pattern suggestive of recent outbreak in two study sites populated predominately by Chinese people.The majority of infections did not give rise to recognizable disease(either asymptomatic or nonspecific symptoms)as only 12.9%of participants(31/240)recalled having dengue in the past.Conclusions:The predominantly rural community under study had a very high previous exposure to dengue.The finding of a high proportion of unreported cases possibly due to subclinical infections underscores the need for enhanced surveillance and control methods.This finding also has implications for measuring disease burden,understanding transmission dynamics,and hypothesizing effects on DENV vaccine efficacy and uptake. | Amreeta Dhanoa Sharifah Syed Hassan Nowrozy Kamar Jahan Daniel D.Reidpath Quek Kia Fatt Mohtar Pungut Ahmad Cheong Yuet Meng Lau Wee Ming Anuar Zaini Zain Maude Elvira Phipps Iekhsan Othman Aman Bin Rabu Rowther Sirajudeen Ahmad Abdul Basitz Ahmad Fatan Faidzal Adlee Ghafar Hamdan Bin Ahmad Pascale Allotey | 2018 | Infectious Diseases of Poverty2018，7，1： | 0 |
