  1. Managing anticoagulation and antiplatelet medications in GI endoscopy: a survey comparing the East and the West
    Lee SY, Tang SJ, Rockey DC, Weinstein D, Lara L, Sreenarasimhaiah J, et al.
    Gastrointest Endosc, 2008 Jun;67(7):1076-81.
    PMID: 18384789 DOI: 10.1016/j.gie.2007.11.037
    Anticoagulation and antiplatelet medications may potentiate GI bleeding, and their use may lead to an increased need for a GI endoscopy. We hypothesized that there might be different practice patterns among international endoscopists.

    Nearly every 2 minutes, somewhere in the world, a woman dies because of complications of pregnancy and childbirth. Every such death is an overwhelming catastrophe for everyone confronted with it. Most deaths occur in developing countries, especially in Africa and southern Asia, but a significant number also occur in the developed world.

  3. Fulltext Engaging the ASEAN Diaspora: Type 2 Diabetes Prevalence, Pathophysiology, and Unique Risk Factors among Filipino Migrants in the United States
    Araneta MR
    J ASEAN Fed Endocr Soc, 2019;34(2):126-133.
    PMID: 33442147 DOI: 10.15605/jafes.034.02.02
    Type 2 diabetes prevalence is rising rapidly in Southeast Asia (SEA) where urbanization and adoption of 'western' behavioral lifestyles are attributed as predominant risk factors. The Southeast Asian diaspora to the United States has resulted in a sizable portion of migrant and US born SEAs, with approximately 4 million Filipino Americans, 2 million Vietnamese-Americans, Cambodians (330,000), and Thai (300,000) as the most populous. Their longer exposure to a western lifestyle and participation in clinical studies with other racial/ethnic groups, provide opportunities to evaluate etiologic factors which might inform trends and intervention opportunities among residents of Southeast Asia. Epidemiologic studies in the US have identified higher T2D prevalence among Filipinos (16.1%) compared to groups perceived to be at highest risk for T2D, namely Latinos (14.0%), Black (13.7%), and Native Americans (13.4%), while SEAs (including Burmese, Cambodian, Indonesian, Laotian, Malaysian, and Thai, 10.5%) and Vietnamese (9.9%) had higher T2D risk compared to Whites (7.7%), despite their absence of general obesity. Asian-Americans, including SEAs, East and South Asians, collectively have higher rates of undiagnosed T2D compared to other racial/ethnic groups in the US. Almost half (44%) of Filipinos with newly diagnosed T2D have isolated post-challenge hyperglycemia and will remain undiagnosed if current screening practices remain limited to measures of glycosylated hemoglobin and fasting plasma glucose. The University of California San Diego Filipino Health Study found excess visceral adipose tissue accumulation, low ratio of muscle to total abdominal mass area, low adiponectin concentration, multiparity (≥ 6 live births), and sleep insufficiency (<7 hours) to be unique T2D risk factors among Filipino-American women, even after adjusting for established T2D risk factors including hypertension and parental history of T2D. Social determinants such as low educational attainment (less than college completion), and sustained social disadvantage during childhood and adulthood were independently associated with T2D risk. Gestational diabetes is a known risk factor for future T2DM among women; Northern California data shows that following Asian Indians, gestational diabetes was highest among Filipina and SEA parturients, who had twice the GDM prevalence as Black, Hispanic, and White women. Identification of novel T2D risk factors among SEAs may guide early diagnosis, inform pathophysiology, and identify unique opportunities for T2D prevention and management.

  4. Fulltext Health Profiles of Newly Arrived Refugee Children in the United States, 2006-2012
    Yun K, Matheson J, Payton C, Scott KC, Stone BL, Song L, et al.
    Am J Public Health, 2016 Jan;106(1):128-35.
    PMID: 26562126 DOI: 10.2105/AJPH.2015.302873
    OBJECTIVES: We conducted a large-scale study of newly arrived refugee children in the United States with data from 2006 to 2012 domestic medical examinations in 4 sites: Colorado; Minnesota; Philadelphia, Pennsylvania; and Washington State.

    METHODS: Blood lead level, anemia, hepatitis B virus (HBV) infection, tuberculosis infection or disease, and Strongyloides seropositivity data were available for 8148 refugee children (aged < 19 years) from Bhutan, Burma, Democratic Republic of Congo, Ethiopia, Iraq, and Somalia.

    RESULTS: We identified distinct health profiles for each country of origin, as well as for Burmese children who arrived in the United States from Thailand compared with Burmese children who arrived from Malaysia. Hepatitis B was more prevalent among male children than female children and among children aged 5 years and older. The odds of HBV, tuberculosis, and Strongyloides decreased over the study period.

    CONCLUSIONS: Medical screening remains an important part of health care for newly arrived refugee children in the United States, and disease risk varies by population.

  5. Fulltext Oral health care for children in countries using dental therapists in public, school-based programs, contrasted with that of the United States, using dentists in a private practice model
    Mathu-Muju KR, Friedman JW, Nash DA
    Am J Public Health, 2013 Sep;103(9):e7-e13.
    PMID: 23865650 DOI: 10.2105/AJPH.2013.301251
    The United States faces a significant problem with access to oral health care, particularly for children. More than 50 countries have developed an alternative dental provider, a dental therapist, practicing in public, school-based programs, to address children's access to care. This delivery model has been demonstrated to improve access to care and oral health outcomes while providing quality care economically. We summarize elements of a recent major review of the global literature on the use of dental therapists, "A Review of the Global Literature on Dental Therapists: In the Context of the Movement to Add Dental Therapists to the Oral Health Workforce in the United States." We contrast the success of a school-based model of caring for children by dental therapists with that of the US model of dentists providing care for children in private practices.

  6. Apheresis in developing countries around the World
    Eichbaum Q, Smid WM, Crookes R, Naim N, Mendrone A, Marques JF, et al.
    J Clin Apher, 2015 Aug;30(4):238-46.
    PMID: 25346394 DOI: 10.1002/jca.21368
    At the combined American Society for Apheresis (ASFA) Annual Meeting/World Apheresis Association (WAA) Congress in San Francisco, California, in April of 2014, the opening session highlighted the status of apheresis outside of the United States. The organizers invited physicians active in apheresis in countries not usually represented at such international gatherings to give them a forum to share their experiences, challenges, and expectations in their respective countries with regard to both donor and therapeutic apheresis. Apheresis technology is expensive as well as technically and medically demanding, and low and median income countries have different experiences to share with the rest of the world. Apheresis procedures also require resources taken for granted in the developed world, such as reliable electrical power, that can be unpredictable in parts of the developing world. On the other hand, it was obvious that there are significant disparities in access to apheresis within the same country (such as in Brazil), as well as between neighboring nations in Africa and South America. A common trend in the presentations from Brazil, Indonesia, Malaysia, Nigeria, and South Africa, was the need for more and better physicians and practitioners' training in the indications of the various apheresis modalities and patient oversight during the procedures. As ASFA and WAA continue to work together, and globalization allows for increased knowledge-sharing, improved access to apheresis procedures performed by qualified personnel with safety and high-quality standards will be increasingly available.

  7. Asia-Pacific mussel watch for emerging pollutants: Distribution of synthetic musks and benzotriazole UV stabilizers in Asian and US coastal waters
    Nakata H, Shinohara R, Nakazawa Y, Isobe T, Sudaryanto A, Subramanian A, et al.
    Mar Pollut Bull, 2012 Oct;64(10):2211-8.
    PMID: 22910332 DOI: 10.1016/j.marpolbul.2012.07.049
    We analyzed 68 green and blue mussels collected from Cambodia, China, Hong Kong, India, Indonesia, Japan, Korea, Malaysia, Philippines, Vietnam and the USA during 2003 and 2007, to elucidate the occurrence and widespread distributions of emerging pollutants, synthetic musks and benzotriazole UV stabilizers (BUVSs) in Asia-Pacific coastal waters. Synthetic musks and BUVSs were detected in mussels from all countries, suggesting their ubiquitous contamination and widespread distribution. High concentrations of musks and BUVSs were detected in mussels from Japan and Korea, where the levels were comparable or greater than those of PCBs, DDTs and PBDEs. Significant correlations were found between the concentrations of HHCB and AHTN, and also between the concentrations of UV-327 and UV-328, which suggest similar sources and compositions of these compounds in commercial and industrial products. To our knowledge, this is the first study of large-scale monitoring of synthetic musks and BUVSs in Asia-Pacific coastal waters.

  8. Maternal smoking during pregnancy and self-reported delinquency by offspring
    Ellis L, Widmayer A, Das S
    Crim Behav Ment Health, 2012 Dec;22(5):325-35.
    PMID: 22696101 DOI: 10.1002/cbm.1828
    BACKGROUND: Several studies have reported significant positive correlations between smoking during pregnancy by mothers and the involvement of their offspring in criminal/delinquent behaviour later in life, but these findings have been described as modest and the criminality based on official conviction statistics.
    AIMS: We sought to verify this relationship and probe for more details on the basis of self-reported offending among college students.
    METHODS: Independently completed questionnaires were collected from 6332 students and their mothers. The students provided information about their delinquent acts, if any, according to eight categories. Their mothers provided retrospective reports of their smoking habits, if any, during pregnancy.
    FINDINGS: Mothers who recalled having smoked during pregnancy were significantly more likely than non-smoking mothers to have offspring who self-reported engaging in some types of delinquency. This relationship was more evident for female offspring than for male offspring and was most pronounced for illegal drug use by the offspring. There was, however, no relationship between offspring offending and estimated number of cigarettes smoked by mothers, month of pregnancy when smoked or consistency of smoking throughout pregnancy.
    CONCLUSION: Overall, our study confirms that maternal smoking during pregnancy is associated with offspring involvement in delinquency, but the lack of critical timing or dose-response relationships between maternal smoking and later offspring delinquency cast doubt on the possibility that the associations are due to teratogenic effects of tobacco smoke.

  9. Isoniazid preventive therapy in correctional facilities: a systematic review
    Al-Darraji HA, Kamarulzaman A, Altice FL
    Int J Tuberc Lung Dis, 2012 Jul;16(7):871-9.
    PMID: 22410101 DOI: 10.5588/ijtld.11.0447
    Tuberculosis (TB) remains a major cause of morbidity and mortality worldwide and the main cause of death in correctional facilities in middle- and low-income countries. Due to the closed environment and the concentration of individuals with TB-related risk factors, effective measures are required to control TB in such settings. Isoniazid preventive therapy (IPT) represents an effective and cost-effective measure. Despite international recommendations that IPT be integral to TB control, it is seldom deployed. A systematic review of interventions used to assess IPT initiation and completion in correctional facilities was conducted using published studies from two biomedical databases and relevant keywords. Additional references were reviewed, resulting in 18 eligible studies. Most (72%) studies were conducted in the United States and in jail settings (60%), with the main objective of improving completion rates inside the facility or after release. Studies that provided data about initiation and completion rates showed poor success in correctional facilities. Adverse consequences and treatment interruption ranged from 1% to 55% (median 5%) in reported studies; hepatotoxicity was the most prevalent adverse reaction. Despite its accelerating effect on the development of active TB, information on human immunodeficiency virus (HIV) status was provided in only half of the studies. Among the four studies where IPT effectiveness was assessed, the results mirror those described in community settings. Future studies require thorough assessments of IPT initiation and completion rates and adverse effects, particularly in low- and middle-income countries and where comorbid viral hepatitis may contribute significantly to outcomes, and in settings where TB and HIV are more endemic.

  10. The development of a value based pricing index for new drugs in metastatic colorectal cancer
    Dranitsaris G, Truter I, Lubbe MS
    Eur J Cancer, 2011 Jun;47(9):1299-304.
    PMID: 21493060 DOI: 10.1016/j.ejca.2011.03.015
    Worldwide, prices for cancer drugs have been under downward pressure where several governments have mandated price cuts of branded products. A better alternative to government mandated price cuts would be to estimate a final price based on drug performance, cost effectiveness and a country's ability to pay. We developed a global pricing index for new cancer drugs in patients with metastatic colorectal cancer (mCRC) that encompasses all of these attributes.

    Khoo S, Engelhorn R
    Adapt Phys Activ Q, 2011 Jan;28(1):27-39.
    PMID: 21282846
    Understanding the motivations for people to volunteer with the management and execution of major sporting events is important for the recruitment and retention of the volunteers. This research investigated volunteer motivations at the first National Special Olympics held in Ames, Iowa, USA in July 2006. A total of 289 participants completed the 28 item Special Event Volunteer Motivation Scale. The top motivations related to the purposive incentives of wanting to help make the event a success and to do something good for the community. Factor analysis revealed a five-factor model, with the altruistic factor (purposive) being the most important. A MANCOVA was also used to compare subjects using both gender and experience as independent variables. Small but significant differences in motivation were observed.

  12. Government public health policy: three cautionary tales from Malaysia, South Africa and the United States
    Blum J, Carstens P, Talib N
    Med Law, 2007 Dec;26(4):615-42.
    PMID: 18284107
    Three authors describe problematic scenarios of health policy in their respective countries. These examples illustrate the role of government influences in determining resource allocation, legislation, health provision and health outcomes in very different situations. These outcomes are affected not only by attitudes to public health, but also by the legal systems in the countries which are the subjects of this study. The authors draw conclusions about the use and abuse of public health regulation.

  13. Fulltext Emotional intelligence and perceived stress in dental undergraduates: a multinational survey
    Pau A, Rowland ML, Naidoo S, AbdulKadir R, Makrynika E, Moraru R, et al.
    J Dent Educ, 2007 Feb;71(2):197-204.
    PMID: 17314380
    This multinational survey investigated the relationship between emotional intelligence (EI) and perceived stress (PS) in seven countries. First-year dental undergraduates attending a dental school in England, Greece, Romania, South Africa, Australia, and the United States and three schools in Malaysia were invited to complete a set of questionnaires on age, gender, academic background, satisfaction with career choice, EI, and PS. Of 860 questionnaires distributed, 596 were fully completed--a response rate of 69.3 percent. Mean EI score was 123.8 (95 percent CI 122.7-124.9), and mean PS score was 19.1 (95 percent CI 18.6-19.7). Significant differences in EI and PS scores were detected between different countries. Females (p<0.05), younger students (p<0.001), those without a previous higher education qualification (p<0.001), and those not satisfied with their decision to study dentistry (p<0.001) were more likely to report PS when compared to their counterparts. A significant inverse relationship (coefficient=-0.29, p=0.001) between EI and PS was detected. Independent significant predictors of PS identified were gender (beta=0.22, t=5.71, p=0.001), previous higher education qualification (beta=-0.14, t=-2.42, p=0.010), satisfaction with decision to study dentistry (beta=-0.20, t=-5.11, p=0.001), and EI (beta=-0.24, t=-6.09, p=0.001), with the latter being relatively the most important predictor. In conclusion, the inverse relationship between EI and PS has been confirmed in this heterogeneous sample representing diverse sociocultural and academic contexts of dental undergraduates.

  14. Perfluorooctanesulfonate and related fluorochemicals in human blood from several countries
    Kannan K, Corsolini S, Falandysz J, Fillmann G, Kumar KS, Loganathan BG, et al.
    Environ Sci Technol, 2004 Sep 1;38(17):4489-95.
    PMID: 15461154
    Perfluorooctanesulfonyl fluoride based compounds have been used in a wide variety of consumer products, such as carpets, upholstery, and textiles. These compounds degrade to perfluorooctanesulfonate (PFOS), a persistent metabolite that accumulates in tissues of humans and wildlife. Previous studies have reported the occurrence of PFOS, perfluorohexanesulfonate (PFHxS), perfluorooctanoate (PFOA), and perfluorooctanesulfonamide (PFOSA) in human sera collected from the United States. In this study, concentrations of PFOS, PFHxS, PFOA, and PFOSA were measured in 473 human blood/serum/plasma samples collected from the United States, Colombia, Brazil, Belgium, Italy, Poland, India, Malaysia, and Korea. Among the four perfluorochemicals measured, PFOS was the predominant compound found in blood. Concentrations of PFOS were the highest in the samples collected from the United States and Poland (>30 ng/mL); moderate in Korea, Belgium, Malaysia, Brazil, Italy, and Colombia (3 to 29 ng/mL); and lowest in India (<3 ng/mL). PFOA was the next most abundant perfluorochemical in blood samples, although the frequency of occurrence of this compound was relatively low. No age- or gender-related differences in the concentrations of PFOS and PFOA were found in serum samples. The degree of association between the concentrations of four perfluorochemicals varied, depending on the origin of the samples. These results suggested the existence of sources with varying levels and compositions of perfluorochemicals, and differences in exposure patterns to these chemicals, in various countries. In addition to the four target fluorochemicals measured, qualitative analysis of selected blood samples showed the presence of other perfluorochemicals such as perfluorodecanesulfonate (PFDS), perfluoroheptanoic acid (PFHpA), perfluorononanoic acid (PFNA), perfluorodecanoic acid (PFDA), perfluorododecanoic acid (PFDoA), and perfluoroundecanoic acid (PFUnDA) in serum samples, at concentrations approximately 5- to 10-fold lower than the concentration of PFOS. Further studies should focus on identifying sources and pathways of human exposure to perfluorochemicals.

  15. Inter-observer Variability Analysis of Automatic Lung Delineation in Normal and Disease Patients
    Saba L, Than JC, Noor NM, Rijal OM, Kassim RM, Yunus A, et al.
    J Med Syst, 2016 Jun;40(6):142.
    PMID: 27114353 DOI: 10.1007/s10916-016-0504-7
    Human interaction has become almost mandatory for an automated medical system wishing to be accepted by clinical regulatory agencies such as Food and Drug Administration. Since this interaction causes variability in the gathered data, the inter-observer and intra-observer variability must be analyzed in order to validate the accuracy of the system. This study focuses on the variability from different observers that interact with an automated lung delineation system that relies on human interaction in the form of delineation of the lung borders. The database consists of High Resolution Computed Tomography (HRCT): 15 normal and 81 diseased patients' images taken retrospectively at five levels per patient. Three observers manually delineated the lungs borders independently and using software called ImgTracer™ (AtheroPoint™, Roseville, CA, USA) to delineate the lung boundaries in all five levels of 3-D lung volume. The three observers consisted of Observer-1: lesser experienced novice tracer who is a resident in radiology under the guidance of radiologist, whereas Observer-2 and Observer-3 are lung image scientists trained by lung radiologist and biomedical imaging scientist and experts. The inter-observer variability can be shown by comparing each observer's tracings to the automated delineation and also by comparing each manual tracing of the observers with one another. The normality of the tracings was tested using D'Agostino-Pearson test and all observers tracings showed a normal P-value higher than 0.05. The analysis of variance (ANOVA) test between three observers and automated showed a P-value higher than 0.89 and 0.81 for the right lung (RL) and left lung (LL), respectively. The performance of the automated system was evaluated using Dice Similarity Coefficient (DSC), Jaccard Index (JI) and Hausdorff (HD) Distance measures. Although, Observer-1 has lesser experience compared to Obsever-2 and Obsever-3, the Observer Deterioration Factor (ODF) shows that Observer-1 has less than 10% difference compared to the other two, which is under acceptable range as per our analysis. To compare between observers, this study used regression plots, Bland-Altman plots, two tailed T-test, Mann-Whiney, Chi-Squared tests which showed the following P-values for RL and LL: (i) Observer-1 and Observer-3 were: 0.55, 0.48, 0.29 for RL and 0.55, 0.59, 0.29 for LL; (ii) Observer-1 and Observer-2 were: 0.57, 0.50, 0.29 for RL and 0.54, 0.59, 0.29 for LL; (iii) Observer-2 and Observer-3 were: 0.98, 0.99, 0.29 for RL and 0.99, 0.99, 0.29 for LL. Further, CC and R-squared coefficients were computed between observers which came out to be 0.9 for RL and LL. All three observers however manage to show the feature that diseased lungs are smaller than normal lungs in terms of area.

  17. Emergence of Nipah virus in Malaysia
    Uppal PK
    Ann N Y Acad Sci, 2000;916:354-7.
    PMID: 11193645
    A pig-borne virus causing viral encephalitis amongst human beings in Malaysia was detected in 1997 by the Ministry of Health. Initially, the disease was considered to be Japanese encephalitis. Subsequently, it was thought to be a Hendra-like viral encephalitis, but on 10th April, 1999 the Minister of Health announced this mysterious and deadly virus to be a new virus named Nipah virus. The virus was characterized at CDC, Atlanta, Georgia. The gene sequencing of the enveloped virus revealed that one of the genes had 21% difference in the nucleotide sequence with about 8% difference in the amino acid sequence from Hendra virus isolated from horses in Australia in 1994. The virus was named after the village Nipah. In all, the Ministry of Health declared 101 human casualties, and 900,000 pigs were culled by April, 1999. The worst affected area in Malaysia was Negri Sembilan. The symptoms, incubation period in human being and pigs, animal to human transmission, threat of disease to other livestock, and control program adopted in Malaysia is described.

  18. Flexibility and hardness of dental stainless steel wrought wires used in Thailand
    Benjakul P, Cheunarrom C, Ongthiemsak C
    J Oral Sci, 2001 Mar;43(1):15-9.
    PMID: 11383631
    Stainless steel wrought wires used as clasp arms for removable partial dentures in Thailand were compared with those used in some other countries (in the as-received condition) in terms of flexibility, Vickers microhardness and composition. The results showed that there were significant differences (P< or =0.05) among the wires. A Japanese stainless steel wire (SK) was obviously different from the others. It had the lowest proportional limit and microhardness, but its flexibility was almost the same. The chemical composition of each wire was not greatly different. The wires were about 18-20 wt% chromium and 8-9 wt% nickel, except for the SK wire, which had about 12 wt% nickel.

    PMID: 12108535
    Quality assurance of medical practice requires assessment of doctors' performance, whether informally via a system such as peer review or more formally via one such as credentialing. Current methods of assessment are, however, subjective or implicit. More objective methods of assessment based on statistical process control technique such as cumulative sum (CUSUM) procedure may be helpful.

  20. Comparing perceptions of dental aesthetics in the USA with those in eleven ethnic groups
    Cons NC, Jenny J
    Int Dent J, 1994 Dec;44(6):489-94.
    PMID: 7851991
    The Standard DAI is an orthodontic index based on perceptions of dental aesthetics in the USA. The Standard DAI is a regression equation linking perceptions of the social acceptability of dental aesthetics with the objective intraoral measurements of ten occlusal traits. Since the Standard DAI is based on perceptions of dental aesthetics in the USA it can be used without modification only where perceptions of dental aesthetics are similar to those in the USA. This study was designed to determine whether perceptions of dental aesthetics of students in eleven diverse ethnic groups are similar to those of students in the USA. The same 25 stimuli (photographs of dental configurations, a subset of the 200 stimuli used in deriving the Standard DAI equation) were rated for dental aesthetics by Australian, Chinese, German, Japanese, Korean, Latvian, Native American, Singaporean Chinese, Singaporean Indian, Singaporean Malay, and Thai students. Their ratings were compared with the ratings of the same 25 stimuli by students in the USA. Spearman rank-order correlations ranged from 0.84 to 0.94. These correlations are sufficiently high to show that perceptions of dental aesthetics in all eleven ethnic groups are very similar to the perceptions of USA students. Therefore the Standard DAI can be used without modification in all eleven ethnic groups.
