  1. Women--an endangered species
    World Dev Forum, 1987 Nov 30;5(21):1-2.
    PMID: 12269045
    Throughout India and China, South Korea and Taiwan, Pakistan and Malaysia, the same sentiment recurs: "The birth of girl is an occasion for gloom, not cheer, for bitterness, not pleasure." In all these countries "patriarchal traditions and social stigmas" make females the unwanted sex, reports Asiaweek. The tragic result: prenatal gender tests are flourishing. And for many women, if the test indicates a female, they abort. In India, sex tests and abortions are legal, cheap and readily available. Some 1500 sex-tested girls are aborted annually in Bombay alone. In China, abortions are legal, but gender tests strictly forbidden. Says one official: We cannot afford to let people know what sex the fetus is because all the girls would be aborted." Yet the numbers of baby girls in China have been reduced--and illicit gender tests and female infanticide are considered partly to blame. In South Korea, gender tests have been banned and most abortions are illegal, but "clandestine tests" are available, and according to the government some 30,000 pregnancies are terminated annually. The number of aborted females is not known, but birth ratios have shown "an alarming swing towards males" in recent years. Can laws and education change the social attitudes against girls in these Asian countries? Indian activist Vibhuti Patel, a lobbyist for stronger controls over sex-testing, hopes so. She urges a "continuous campaign" to fight the "centuries-old values" that encourages gender tests. Says Patel: Nothing less than the very survival of women is at stake."

    PIP:
    This paper presents data on contraceptive prevalence from 26 national sample surveys conducted in the Asian and Pacific region during the 1966-84 period. The basic data presented are: contraceptive prevalence rates, cross-classified by age where possible; the percentage of couples using each contraceptive method, also cross-classified by age where possible. To facilitate comparison between countries and across time, the data are presented in a standardized form, both numerically and graphically. Contraceptive prevalence rates range from 1-85% (the highest and lowest ever reported). In the Asian and Pacific region as a whole, the prevalence rate was around 40%, which was about the same level as in the Latin American region. In Africa the prevalence rate was around 12%, and in developed countries around 70%. In the late 1960s, prevalence rates in the Asian and Pacific region were less than 20%. By the early 1980s, contraception had spread throughout all parts of society so that the rates in many countries were over 50%, and in some over 60%. Most of the countries with high prevalence rates were in East and Southeast Asia, and most of those with low prevalence in South Asia. Displayed graphically with the age of wife (from 15-49 years) on the x axis, contraceptive prevalence rates appear as an inverted U, low at both ends of the age range and high in the middle. Curves skewed to the left generally have stronger effects on fertility than those skewed to the right. This is due to the fact that most births occur among younger couples and contraception used by younger couples prevents more births than contraception used by older couples. The curves of countries relying primarily on sterilization are generally skewed to the right. The data show a wide variation in the mix of contraceptives used in each country. The use of various contraceptives by age is similar throughout the region. Young couples generally use oral contraceptives (OCs), those in the middle of the reproductive ages the IUD, and those near the end of the childbearing ages sterilization. Rhythm and withdrawal methods appear to be preferred both by couples in the youngest and oldest age groups. Contraceptive needs change as couples progress through the life cycle. Consequently, family planning programs must work to provide a broad mix of contraceptives. The tables show that Thailand and the Republic of Korea, 2 countries which are thought to have excellent family planning programs, have provided well-balanced mixes of contraceptives. Other countries in the region have depended on only 1 or 2 methods.

  6. Lung injury related to consuming Sauropus androgynus vegetable
    Wu CL, Hsu WH, Chiang CD, Kao CH, Hung DZ, King SL, et al.
    J. Toxicol. Clin. Toxicol., 1997;35(3):241-8.
    PMID: 9140317 DOI: 10.3109/15563659709001207
    BACKGROUND: Taking Sauropus androgynus, a Malaysian food, to reduce weight began as a fad in Taiwan in 1994. Some advocates of this fad developed pulmonary dysfunction. The aim of this study is to report the lung injury in patients taking Sauropus androgynus.

    METHODS: From July 1995 to November 1995, we investigated 104 nonsmoking patients (one male and 103 females) with chest roentgenography, pulmonary function, test, and Technetium 99m-labeled diethylene triamine penta-acetate (Tc-99m DTPA) radioaerosol inhalation lung scintigraphy.

    RESULTS: Among the 90 patients receiving Tc-99m DTPA inhalation lung scan, 46 (51.1%) patients had increased clearance of Tc-99m DTPA from lung and 20 (22.2%) patients had inhomogeneous deposition of the submicronic radioaerosol. Eighteen (18/100) patients had obstructive ventilatory impairment in pulmonary function test. Analyzing the results, we found that the patients with respiratory symptoms (n = 42) took more vegetables (p = 0.016), had increased clearance of Tc-99m DTPA (p = 0.010) and had lower FEV1 (p = 0.001), FEV1/FVC (p < 0.001), FEF25-75 (p = 0.001), VC (p = 0.002) and DLCO (p = 0.009) than the patients without respiratory symptoms (n = 62). FEV1 and FEV1/FVC were significantly reduced in patients with severe impairment of alveolar permeability. The cumulative dosage and duration of exposure were significantly associated with the reduction of FEV1 and FEV1/FVC.

    CONCLUSION: The lung injury after taking Sauropus androgynus involves alveoli and/or small airways and is manifest as obstructive ventilatory impairment with inhomogeneous aerosol distribution and increased lung epithelial permeability.

    Meng SL, Yan JX, Xu GL, Nadin-Davis SA, Ming PG, Liu SY, et al.
    Virus Res, 2007 Mar;124(1-2):125-38.
    PMID: 17129631
    A group of 31 rabies viruses (RABVs), recovered primarily from dogs, one deer and one human case, were collected from various areas in China between 1989 and 2006. Complete G gene sequences determined for these isolates indicated identities of nucleotide and amino acid sequences of >or=87% and 93.8%, respectively. Phylogenetic analysis of these and some additional Chinese isolates clearly supported the placement of all Chinese viruses in Lyssavirus genotype 1 and divided all Chinese isolates between four distinct groups (I-IV). Several variants identified within the most commonly encountered group I were distributed according to their geographical origins. A comparison of representative Chinese viruses with other isolates retrieved world-wide indicated a close evolutionary relationship between China group I and II viruses and those of Indonesia while China group III viruses formed an outlying branch to variants from Malaysia and Thailand. China group IV viruses were closely related to several vaccine strains. The predicted glycoprotein sequences of these RABVs variants are presented and discussed with respect to the utility of the anti-rabies biologicals currently employed in China.

    Tan EC, Lim Y, Teo YY, Goh R, Law HY, Sia AT
    J Pain, 2008 Sep;9(9):849-55.
    PMID: 18550441 DOI: 10.1016/j.jpain.2008.04.004
    There are reports suggesting that sensitivity to and tolerance of both clinical and experimental pain differ among ethnic groups. We examined self-rated pain score and morphine usage in 1034 women who underwent elective lower cesarian section (LSCS) for their deliveries. Data on pain scores and amount of total morphine use according to patient-controlled analgesia were collected every 4 hours. Overall, lowest pain scores were recorded 12 hours after surgery and highest at 24 hours. Morphine consumption was highest within the first 4 hours and lowest between 12 and 16 hours. There were statistically significant ethnic group differences in pain scores (P = 1.7 x 10(-7)) and morphine usage (P = 2.8 x 10(-15)) between ethnic groups, with Indians having the highest mean pain score and using the highest amount of morphine. The ethnic differences in pain score and morphine self-administration persisted after controlling for age, body mass index, and duration of operation.

  9. Molecular epidemiology of rabies virus in Vietnam (2006-2009)
    Nguyen AK, Nguyen DV, Ngo GC, Nguyen TT, Inoue S, Yamada A, et al.
    Jpn J Infect Dis, 2011;64(5):391-6.
    PMID: 21937820
    This study was aimed at determining the molecular epidemiology of rabies virus (RABV) circulating in Vietnam. Intra vitam samples (saliva and cerebrospinal fluid) were collected from 31 patients who were believed to have rabies and were admitted to hospitals in northern provinces of Vietnam. Brain samples were collected from 176 sick or furious rabid dogs from all over the country. The human and canine samples were subjected to reverse transcription-polymerase chain reaction analysis. The findings showed that 23 patients tested positive for RABV. Interestingly, 5 rabies patients did not have any history of dog or cat bites, but they had an experience of butchering dogs or cats, or consuming their meat. RABV was also detected in 2 of the 100 sick dogs from slaughterhouses. Molecular epidemiological analysis of 27 RABV strains showed that these viruses could be classified into two groups. The RABVs classified into Group 1 were distributed throughout Vietnam and had sequence similarity with the strains from China, Thailand, Malaysia, and the Philippines. However, the RABVs classified into Group 2 were only found in the northern provinces of Vietnam and showed high sequence similarity with the strain from southern China. This finding suggested the recent influx of Group 2 RABVs between Vietnam and China across the border. Although the incidence of rabies due to circulating RABVs in slaughterhouses is less common than that due to dog bite, the national program for rabies control and prevention in Vietnam should include monitoring of the health of dogs meant for human consumption and vaccination for workers at dog slaughterhouses. Further, monitoring of and research on the circulating RABVs in dog markets may help to determine the cause of rabies and control the spread of rabies in slaughterhouses in Vietnam.

    Nishiki I, Minami T, Chen SC, Itami T, Yoshida T
    J Gen Appl Microbiol, 2012;58(6):457-63.
    PMID: 23337581
    Group C Streptococcus dysgalactiae (GCSD) is a pathogen of farmed fish. Almost all GCSD isolates from Asian countries, including Japan, Taiwan, Malaysia, and China, have a serum opacity factor (SOF-FD). Although the SOF-FD sequences in different GCSD isolates are identical, different opacification activities are observed. Three types of variations were observed in the upstream sequence of the sof-FD gene in GCSD isolates with different SOF-FD activities. Type 1 was characterized by insertion of an IS981-like element into the upstream region of the sof-FD gene. In Type 2, an IS981-like element was inserted into the upstream region in a direction opposite to that in Type 1. In Type 3, no IS element was inserted. Type 1 was predominant among Japanese isolates (129 of 133). Isolates from other Asian countries were generally Type 3 (13 of 16). Except for 1 strain, Type 1 strains exhibited opacification activities with optical densities (ODs)>0.6, while Type 2 and Type 3 strains have low opacification activities (ODs >0.2). Only Type 1 strains have putative -10 and -35 promoter regions upstream of the sof-FD gene, and the expression level of the sof-FD gene was higher in Type 1 strains than in Type 2 and Type 3 strains.

  12. Fulltext Association of the lupus low disease activity state (LLDAS) with health-related quality of life in a multinational prospective study
    Golder V, Kandane-Rathnayake R, Hoi AY, Huq M, Louthrenoo W, An Y, et al.
    Arthritis Res Ther, 2017 03 20;19(1):62.
    PMID: 28320433 DOI: 10.1186/s13075-017-1256-6
    BACKGROUND: Systemic lupus erythematosus (SLE) is associated with significant impairment of health-related quality of life (HR-QoL). Recently, meeting a definition of a lupus low disease activity state (LLDAS), analogous to low disease activity in rheumatoid arthritis, was preliminarily validated as associated with protection from damage accrual. The LLDAS definition has not been previously evaluated for association with patient-reported outcomes. The objective of this study was to determine whether LLDAS is associated with better HR-QoL, and examine predictors of HR-QoL, in a large multiethnic, multinational cohort of patients with SLE.
    METHODS: HR-QoL was measured using the Medical Outcomes Study 36-item short form health survey (SF-36v2) in a prospective study of 1422 patients. Disease status was measured using the SLE disease activity index (SLEDAI-2 K), physician global assessment (PGA) and LLDAS.
    RESULTS: Significant differences in SF-36 domain scores were found between patients stratified by ethnic group, education level and damage score, and with the presence of active musculoskeletal or cutaneous manifestations. In multiple linear regression analysis, Asian ethnicity (p China, Indonesia, Philippines, Singapore, Taiwan, Thailand)

    In 2010 the international HIV/AIDS community called on countries to take action to prevent HIV transmission among people who inject drugs (PWID). To set a baseline we proposed an "accountability matrix", focusing upon six countries accounting for half of the global population of PWID: China, Malaysia, Russia, Ukraine, Vietnam and the USA. Two years on, we review progress.

  14. Fulltext Identification of a novel Getah virus by Virus-Discovery-cDNA random amplified polymorphic DNA (RAPD)
    Hu T, Zheng Y, Zhang Y, Li G, Qiu W, Yu J, et al.
    BMC Microbiol, 2012;12:305.
    PMID: 23268691 DOI: 10.1186/1471-2180-12-305
    The identification of new virus strains is important for the study of infectious disease, but current (or existing) molecular biology methods are limited since the target sequence must be known to design genome-specific PCR primers. Thus, we developed a new method for the discovery of unknown viruses based on the cDNA--random amplified polymorphic DNA (cDNA-RAPD) technique. Getah virus, belonging to the family Togaviridae in the genus Alphavirus, is a mosquito-borne enveloped RNA virus that was identified using the Virus-Discovery-cDNA RAPD (VIDISCR) method.

    Ann Rheum Dis, 2017 Aug;76(8):1436-1439.
    PMID: 28478399 DOI: 10.1136/annrheumdis-2017-211073
    OBJECTIVE: We evaluate the efficacy of human umbilical cord-derived mesenchymal stem cell (hUC-MSC) for the treatment of lupus nephritis (LN). Previous reports showed hUC-MSC could have dramatic treatment effect.

    METHODS: Eighteen patients with WHO class III or IV LN were randomly assigned to hUC-MSC (dose 2×108 cells) or placebo. All patients received standard immunosuppressive treatment, which consisted of intravenous methylprednisolone and cyclophosphamide, followed by maintenance oral prednisolone and mycophenolate mofetil.

    RESULTS: Remission occurred in 9 of 12 patients (75%) in the hUC-MSC group and 5 of 6 patients (83%) in the placebo group. Remission was defined as stabilisation or improvement in renal function, reduction in urinary red cells and protein. A similar proportion of patients on hUC-MSC and placebo achieved complete remission. Improvements in serum albumin, complement, renal function, Systemic Lupus Erythematosus Disease Activity Index and British Isles Lupus Assessment Group scores were similar in both groups. One patient on placebo had a stroke and another had ascites. One patient on hUC-MSC had leucopenia, pneumonia and subcutaneous abscess and another died of severe pneumonia. The trial was abandoned after 18 patients were enrolled when it had become obvious it would not demonstrate a positive treatment effect.

    CONCLUSION: hUC-MSC has no apparent additional effect over and above standard immunosuppression.

  16. Fulltext Network analysis of the depressive symptom profiles in Asian patients with depressive disorders: Findings from the Research on Asian Psychotropic Prescription Patterns for Antidepressants (REAP-AD)
    Park SC, Jang EY, Xiang YT, Kanba S, Kato TA, Chong MY, et al.
    Psychiatry Clin Neurosci, 2020 Jun;74(6):344-353.
    PMID: 32048773 DOI: 10.1111/pcn.12989
    AIM: We aimed to estimate the network structures of depressive symptoms using network analysis and evaluated the geographic regional differences in theses network structures among Asian patients with depressive disorders.

    METHODS: Using data from the Research on Asian Psychotropic Prescription Patterns for Antidepressants (REAP-AD), the network of the ICD-10 diagnostic criteria for depressive episode was estimated from 1174 Asian patients with depressive disorders. The node strength centrality of all ICD-10 diagnostic criteria for a depressive episode was estimated using a community-detection algorithm. In addition, networks of depressive symptoms were estimated separately among East Asian patients and South or Southeast Asian patients. Moreover, networks were estimated separately among Asian patients from high-income countries and those from middle-income countries.

    RESULTS: Persistent sadness, fatigue, and loss of interest were the most centrally situated within the network of depressive symptoms in Asian patients with depressive disorders overall. A community-detection algorithm estimated that when excluding psychomotor disturbance as an outlier, the other nine symptoms formed the largest clinically meaningful cluster. Geographic and economic variations in networks of depressive symptoms were evaluated.

    CONCLUSION: Our findings demonstrated that the typical symptoms of the ICD-10 diagnostic criteria for depressive episode are the most centrally situated within the network of depressive symptoms. Furthermore, our findings suggested that cultural influences related to geographic and economic distributions of participants could influence the estimated depressive symptom network in Asian patients with depressive disorders.

    AIMS/HYPOTHESIS: Most genetic variants identified for type 2 diabetes have been discovered in European populations. We performed genome-wide association studies (GWAS) in a Chinese population with the aim of identifying novel variants for type 2 diabetes in Asians.

    METHODS: We performed a meta-analysis of three GWAS comprising 684 patients with type 2 diabetes and 955 controls of Southern Han Chinese descent. We followed up the top signals in two independent Southern Han Chinese cohorts (totalling 10,383 cases and 6,974 controls), and performed in silico replication in multiple populations.

    RESULTS: We identified CDKN2A/B and four novel type 2 diabetes association signals with p

  18. Succinic Semialdehyde Dehydrogenase Deficiency in a Chinese Boy: A Novel ALDH5A1 Mutation With Severe Phenotype
    Tay CG, Ariffin H, Yap S, Rahmat K, Sthaneshwar P, Ong LC
    J Child Neurol, 2015 Jun;30(7):927-31.
    PMID: 25122112 DOI: 10.1177/0883073814540523
    Succinic semialdehyde dehydrogenase deficiency is a rare autosomal recessive disorder affecting catabolism of the neurotransmitter gamma-aminobutyric acid (GABA), with a wide range of clinical phenotype. We report a Malaysian Chinese boy with a severe early onset phenotype due to a previously unreported mutation. Urine organic acid chromatogram revealed elevated 4-hydroxybutyric acid. Magnetic resonance imaging (MRI) of the brain demonstrated cerebral atrophy with atypical putaminal involvement. Molecular genetic analysis showed a novel homozygous 3-bp deletion at the ALDH5A1 gene c.1501_1503del (p.Glu501del). Both parents were confirmed to be heterozygotes for the p.Glu501del mutation. The clinical course was complicated by the development of subdural hemorrhage probably as a result of rocking the child to sleep for erratic sleep-wake cycles. This case illustrates the need to recognize that trivial or unintentional shaking of such children, especially in the presence of cerebral atrophy, can lead to subdural hemorrhage.

  19. Immunomodulatory Properties of Water-Soluble Polysaccharides Extracted from the Fruiting Body of Chinese Caterpillar Mushroom, Ophiocordyceps sinensis Cultivar OCS02® (Ascomycetes)
    Yap ACS, Li X, Yap YHY, Razif MFM, Jamil AHA, Ng ST, et al.
    Int J Med Mushrooms, 2020;22(10):967-977.
    PMID: 33426826 DOI: 10.1615/IntJMedMushrooms.2020036351
    Ophiocordyceps sinensis (=Cordyceps sinensis) has been known for its various medicinal properties, in particular immunomodulatory activities associated with its polysaccharides. In this study, the fruiting body of O. sinensis cultivar OCS02® was investigated for its chemical composition and monosaccharide profile. Cold water extract (CWE) obtained from this fruiting body was fractionated by molecular weight (MW) into high (HMW), medium (MMW), and low (LMW) fractions. Polysaccharides in the extract and fractions were identified as heteroglycans containing mostly glucose and mannose with small amounts of galactose, fucose, arabinose, and xylose. The immunomodulatory potential of these heteroglycans was evaluated by induction of cytokine/chemokine secretion using murine macrophage RAW 264.7. All treatments showed significant modulation of IL-6, IL-9, MIP-2, and TIMP-1, especially for CWE, HMW, and MMW, which might be due to their high ratios of glucose and the presence of protein. Further investigation on the structure-function relationship of these fruiting body polysaccharide fractions is needed to delineate the underlying mechanism of their immunomodulatory effect both in vitro and in vivo.

  20. Fulltext Potential Effect of Polyphenolic-Rich Fractions of Corn Silk on Protecting Endothelial Cells against High Glucose Damage Using In Vitro and In Vivo Approaches
    Hamzah N, Safuan S, Wan Ishak WR
    Molecules, 2021 Jun 16;26(12).
    PMID: 34208534 DOI: 10.3390/molecules26123665
    Endothelial cell dysfunction is considered to be one of the major causes of vascular complications in diabetes. Polyphenols are known as potent antioxidants that can contribute to the prevention of diabetes. Corn silk has been reported to contain polyphenols and has been used in folk medicine in China for the treatment of diabetes. The present study aims to investigate the potential protective role of the phenolic-rich fraction of corn silk (PRF) against injuries to vascular endothelial cells under high glucose conditions in vitro and in vivo. The protective effect of PRF from high glucose toxicity was investigated using human umbilical vein endothelial cells (HUVECs). The protective effect of PRF was subsequently evaluated by using in vivo methods in streptozotocin (STZ)-induced diabetic rats. Results showed that the PRF significantly reduced the cytotoxicity of glucose by restoring cell viability in a dose-dependent manner. PRF was also able to prevent the histological changes in the aorta of STZ-induced diabetic rats. Results suggested that PRF might have a beneficial effect on diabetic patients and may help to prevent the development and progression of diabetic complications such as diabetic nephropathy and atherosclerosis.
