National guidance on sexual health in England recommends service development to meet the specific needs of ethnic minority populations. Our aim was to evaluate mode of referral, number of sexually transmitted infections (STIs) diagnosed, and the offering and uptake of HIV testing in patients of South Asian ethnicity. A retrospective case-control study was undertaken in two London genito-urinary (GU) medicine clinics. There were 250 case-control pairs with approximately equal numbers of men and women. South Asians were less likely to have an STI (Odds ratio [OR] 0.66, 95% confidence interval [CI] 0.45, 0.97) or to report risk factors for HIV (OR 0.45, 95% CI 0.28, 0.71). Offering and uptake of HIV antibody testing were high in both South Asian and non-South Asian groups (OR 0.62, 95% CI 0.27, 1.51). South Asians were significantly more likely than controls to have been referred by other medical services rather than self-referred (OR 2.00, 95% CI 1.32, 3.01), which is in keeping with poorer access to GU medicine services in London. 相似文献

INTRODUCTION: The frequent occurrence of prenatal hypertrophy of the muscular ventricular septum has been widely reported in fetuses of diabetic mothers. OBJECTIVES: This experimental study was carried out to test the hypothesis that the weight of the heart, the ratio of the cardiac weight to that of the body, the thickness of the muscular ventricular septum, and the myocytic profile within the ventricular septum are all increased in fetuses of diabetic rats in comparison to fetuses of normal rats. METHODS: Diabetes was induced in 5 pregnant Wistar rats, bearing 30 fetuses, on the eighth day after conception, by intraperitoneal injection of 50 mg/kg of streptozotocin. Five normal pregnant Wistar rats, bearing 20 fetuses, made up the control group. Morphometric data were obtained by a computer-assisted method applied to the measurements of the thickness of the ventricular septum, and myocytic nuclear area. Statistical analysis utilized Student's t-test and Kruskal-Wallis test. RESULTS: The mean thickness of the septum was 675.56 microm (+/-159) in the control fetuses, and 904.39 microm (+/-262) in the fetuses carried by diabetic mothers (p < 0.001). The cardiac weight was 0.016 g (+/-0.004) in the control group, and 0.023 g (+/-0.005) in the group of diabetic fetuses (p < 0.001). The ratio of cardiac to body weight was 0.294% (+/-0.079) in the control group, and 0.514% (+/-0.073) in the diabetic group (p < 0.001). The myocytic nuclear area was 14.70 microm2 in the control group, and 21.43 microm2 in the diabetic group (p < 0.001). CONCLUSIONS: The presence of cellular and morphologic cardiac hypertrophy in fetuses of diabetic rats was demonstrated by the significant difference between the two groups for each analyzed feature. 相似文献

AIMS: Alongside a rising prevalence of known diabetes, patterns of care for diabetes have been changing in the United Kingdom. The aim of this study is to describe the changes in the prevalence of known diabetes and shift in site of care of patients in a single health district over a 10-year period. METHODS: Repeat cross-sectional study over 10 years of patients with diabetes resident in North Tyneside district. RESULTS: The crude prevalence of known diabetes in North Tyneside rose from 1.1 to 3.0% between 1991 and 2001. The proportion of patients receiving their diabetes care wholly in primary care rose significantly from 608/2236 (27%) in 1991 to 3995/5809 (69%) in 2001 (chi(2) = 968, 1 d.f., P < 0.001). The number of patients attending secondary care also rose by 14% over this period of time from 1508 to 1712 patients. CONCLUSIONS: Most of the extra workload of the rising prevalence of diabetes has been met in primary care. However, hospital care has not seen a drop in workload. This has important implications for health care planning, as an increase in resources will be required within both primary and secondary care to meet the needs of the diabetic population. 相似文献

Bacterial arthritis in an English health district: a 10 year review. 总被引:10,自引:7,他引:3
Bacterial arthritis continues to present a difficult clinical and therapeutic problem, necessitating prompt diagnosis and intensive therapy. This study comprises a 10 year review of the condition in an English health district, with particular reference to aetiology, presentation, treatment, and outcome. Although the causative organisms remain qualitatively unchanged, increasing numbers of patients are elderly, immunosuppressed, or have underlying arthropathy. Factors which influence outcome include age, causative organism, joint involved, and delay in diagnosis. Attention is drawn to the notably poor outcome of hip infections in the elderly. 相似文献

Epidemiology of diabetes in Asians of the Indian subcontinent 总被引:2,自引:0,他引:2
Asians from the Indian subcontinent have received greater attention in diabetes studies because of their migration in large numbers. The prevalence of non-insulin-dependent diabetes mellitus (NIDDM) in migrant Indians is higher than that in the population residing in the Indian subcontinent and is also usually higher than in the other racial groups in the host country. However, before drawing any conclusions with reference to the high prevalence of NIDDM in the migrant Indians, careful comparisons are required with more up-to-date information available from the Indian subcontinent itself. Recent data from India indeed indicate that the prevalence rates have either been underestimated in the past or are rising. The problem is compounded by the different diagnostic criteria used for defining diabetes. Some of the possible factors which cause variations in the rates of NIDDM in this population are discussed. 相似文献

Knowledge of diabetes in Asians and Europeans with and without diabetes: the Coventry Diabetes Study. 总被引:3,自引:0,他引:3
Knowledge about the nature, symptoms, complications, and treatment of diabetes was assessed among United Kingdom Europeans and Asians with and without diabetes during the Coventry Diabetes Study. An open questionnaire was validated for use among Asians and Europeans and a 'Knowledge Index' constructed. The questions were answered by 3814 (87%) of 4395 Asians and 3783 (69%) of 5508 Europeans. Among those with known diabetes, 216 (96%) of 223 Asians and 98 (94%) of 104 Europeans answered the questions. The nature of diabetes was unknown in 30% of Europeans and 44% of Asians with diabetes, and 42% and 67%, respectively, could not name a single complication. Most of those without diabetes were unable to name either a complication (Europeans 66%, Asians 89%) or a single symptom (66% and 83%, respectively). The Knowledge Index was highest in Europeans, increased with increasing educational achievement, and was lowest in non-diabetic subjects without a family history of diabetes. Even those with diabetes had a low Knowledge Index. 相似文献

Cardiovascular disease (CVD) is one of the main causes of mortality and morbidity worldwide. As an emerging population, South Asians (SAs) bear a disproportionately high burden of CVD relative to underlying classical risk factors, partly attributable to a greater prevalence of insulin resistance and diabetes and distinct genetic and epigenetic influences. While the phenotypic distinctions between SAs and other ethnicities in CVD risk are becoming increasingly clear, the biology of these conditions remains an area of active investigation, with emerging studies involving metabolism, genetic variation and epigenetic modifiers (e.g., extracellular RNA). In this review, we describe the current literature on prevalence, prognosis and CVD risk in SAs, and provide a landscape of translational research in this field toward ameliorating CVD risk in SAs. 相似文献

Genetic susceptibility factors of Type 1 diabetes in Asians 总被引:1,自引:0,他引:1
Type 1 diabetes is a multifactorial disease in which the insulin producing beta-cells of the pancreas are destroyed by the immune system, a process determined by the activity of major histocompatibility complex (MHC)-restricted T lymphocytes. Progress has been made in elucidating genetic factors involved in Type 1 diabetes in Caucasians, with less data available from Asia. For Asians, the human MHC locus (HLA region), especially the class II region, is the major susceptibility interval. The role of IDDM2, the insulin locus, has been questioned in Asia. In contrast to Caucasians, Asian populations have a very low incidence of Type 1 diabetes (0.4-1.1 cases/year/100 000 individuals). This low incidence rate in the Asian population may be related to the population frequency distribution of susceptible Type 1 diabetes genes, especially of HLA. The overall risk for Type 1 diabetes from HLA DR and DQ is determined by polymorphic residues (alleles) and particular combinations of alleles (haplotypes and genotypes) in a given individual. In Asians, it is very common that a protective DR4 allele is associated with susceptible DQ alleles while neutral/protective DQ alleles are associated with the susceptible DR4 alleles. Our analyses indicate that the counterbalancing between susceptible DRB1 and protective DQB1, and vice versa, is a factor that may contribute to the low incidence of diabetes in Asians. We find that identical HLA DRB1-DQB1 haplotypes of Asians and Caucasians have similar transmission to diabetic children and similar associations with diabetes. Moreover, the association with diabetes and transmission to a diabetic offspring of DR4 haplotypes varies depending on the haplotype borne on the homologous chromosome. This might contribute not only to the synergistic effect of DR3/4, but also to the susceptibility influence of DQB1*0401 haplotypes confined to DR4/X. High-risk DR4 subtypes were predominant in DR4/X, whereas protective DR4 subtypes were observed mainly in the DR3/4 genotype. Since in Asians DQB1*0401 is in linkage disequilibrium (LD) with DRB1*0405, we find more DRB1*0405-DQB1*0401 haplotypes in patients with DR4/X than in patients with DR3/4, suggesting that the contribution of the DRB1 locus may be greater in DR4/X than in DR3/4 genotypes. Several genome scans suggested additional susceptibility intervals and provided supporting evidence for several previously reported linkages. Other studies focused on the confirmation of linkage using multipoint sib-pair analyses with densely spaced markers and multiethnic collection of families. Although significant and consistent linkage evidence was reported for the susceptibility intervals IDDM12 (on 2q33) even in Asia, evidence for most other intervals varies in different data sets. LD mapping has become an increasingly important tool for both confirmation and fine-mapping of susceptibility intervals, as well as identification of etiological mutations. The examination of large and ethnically varied data sets including those of Asia has allowed identification of haplotypes that differ only at a single codon in a single locus. As more data become available, the study of pairs of haplotypes which differ at a single polymorphic site, but have different effects on disease susceptibility, should allow more precise definition of the polymorphisms involved in the disease process. 相似文献

Immigrants from the Indian subcontinent (South Asians) in England and Wales have higher morbidity and mortality from coronary heart disease than the general population; this seems to apply to both Hindus and Muslims. Studies in north west London and Trinidad found that the increased risk of coronary heart disease in Indians was not explained by dietary fat intakes, smoking, blood pressure, or plasma lipids. In the present study the distribution of coronary risk factors was measured in an East London borough where the mortality and attack rate from coronary heart disease are higher in the Asian population, predominantly Muslims from Bangladesh, than in the rest of the population. In a sample of 253 men and women aged 35-69 from general practice, mean plasma cholesterol concentrations were lower in Bangladeshi than in European men and women. Mean systolic blood pressures were 10 mm Hg lower in Bangladeshis. Plasma fibrinogen concentrations were similar in Bangladeshis and Europeans and factor VII coagulant activity was lower in Bangladeshi than in European men. In contrast with the findings in Hindus in north west London, smoking rates were high in Bangladeshi men and the ratio of polyunsaturated fatty acids to saturated fatty acids in plasma lipids was lower in Bangladeshis than in Europeans. Diabetes was three times more common in Bangladeshis than in Europeans and serum insulin concentrations measured after a glucose load were twice as high in Bangladeshis. High insulin concentrations in Bangladeshis were associated with high plasma triglyceride and low high-density lipoprotein cholesterol concentrations. Insulin resistance, leading to diabetes, hyperinsulinaemia, and secondary lipoprotein disturbances, is a possible mechanism for the high rates of coronary heart disease in South Asians in Britain and overseas. 相似文献

Background: Data about the immigrant population living in Spain, their lifestyle habits, and risk factors for gestational diabetes mellitus (GDM) are limited. Thus, the aim of the present study was to describe risk factors for the onset of GDM, the evolution of gestation and delivery, and newborns of Hispanic women living in Spain compared with those of Spanish women. Methods: A semiquantitative questionnaire regarding lifestyle habits was administered to 459 pregnant women (115 Hispanic) with a positive O’Sullivan test (24–28 weeks gestation) between 1 April 2007 and 31 March 2008. Information was collected regarding gestation, delivery, and the newborn. Results: The prevalence of GDM increased with mother’s age, pregestational overweight/obesity, and multiparity. In addition, GDM was associated with lower pregestational fiber and a lower intake of low glycaemic index foods in Hispanic women. The odds ratios (OR) for the total population were 2.53 (95% confidence interval [CI] 1.28–5.01) for overweight, 3.68 (95% CI 1.72–7.90) for obesity, 3.83 (95% 2.03–7.23) for age ≥35 years, and 1.64 (95% CI 1.02–3.01) for multiparity. Newborns from the Hispanic population were significantly heavier than newborns from Spanish women and the rate of Caesarean delivery was significantly higher in the Hispanic population with GDM compared with those without GDM. Conclusions: The immigrant Hispanic population living in Spain trends to acquire the same risk factors associated with lifestyle to the indigenous population. Preventive strategies must stress increased physical activity and fiber intake, decreased intake of sweetened beverages, and an effective reduction in body weight before pregnancy. 相似文献

AIMS: There is increasing evidence suggesting that leptin plays a major role in the regulation of energy homeostasis, as well as in the neuroendocrine and reproductive systems. Leptin is synthesized in the human placenta. The aim of this study was to relate serum leptin levels during pregnancy to glucose tolerance, body mass index (BMI) and specific metabolic variables, such as specific insulin and proinsulin. METHODS: A 2-h 75 g oral glucose tolerance test was performed in 221 pregnant women at 22-29 weeks of gestation (median 25th week). Serum leptin was measured using a radioimmunoassay. In 49 women, sequential leptin measurements were performed (during pregnancy and post partum (median 5 months)). RESULTS: During pregnancy serum leptin was significantly related to body weight (r = 0.49), BMI (r = 0.51), fasting immunoreactive insulin (r = 0.46), specific insulin (r = 0.43) and proinsulin (r = 0.29) (all P-values <0.0001). In women with mild gestational diabetes (GDM, n = 55), leptin levels were lower compared to women with normal glucose tolerance (n = 166) after adjusting for BMI and fasting insulin (26.9 vs. 19.4 ng/ml, P = 0.0001). Leptin was significantly higher during pregnancy compared to post partum (mean +/- SE: 24.3+/-1.5 vs. 19.6+/-1.6 ng/ml, P = 0.0003), even after adjustment for changes in BMI and changes in fasting insulin (P = 0.013). CONCLUSIONS: Leptin levels are elevated in pregnancy. Women with mild GDM presented with relative hypoleptinaemia compared to women with normal glucose tolerance. 相似文献

OBJECTIVE: The mechanisms underlying insulin resistance during normal pregnancy, and its further exacerbation in pregnancies complicated by gestational diabetes mellitus (GDM), are generally unknown. Inositolphosphoglycan P-type (P-IPG), a putative second messenger of insulin, correlates with the degree of insulin resistance in diabetic subjects. An increase during normal pregnancy, in maternal and fetal compartments, has recently been reported. METHODS: A cross-sectional study was carried out in 48 women with GDM and 23 healthy pregnant women. Urinary levels of P-IPG were assessed spectrophotometrically by the activation of pyruvate dehydrogenase phosphatase in urinary specimens and correlated with clinical parameters. RESULTS: Urinary excretion of P-IPG was higher in GDM than in control women (312.1 +/- 151.0 vs. 210.6 +/- 82.7 nmol NADH/min/mg creatinine, P < 0.01) with values increasing throughout pregnancy in control subjects (r2 = 0.34, P < 0.01). P-IPG correlated with blood glucose levels (r(2) = 0.39, P < 0.01 for postprandial glycaemia and r2 = 0.18 P < 0.01 for mean glycaemia) and birthweight in the diabetic group (r2 = 0.14, P < 0.01). CONCLUSIONS: Increased P-IPG urinary excretion occurs in GDM and positively correlates with blood glucose levels. P-IPG may play a role in maternal glycaemic control and, possibly, fetal growth in GDM. 相似文献

Epidemiology of gestational diabetes mellitus and its association with Type 2 diabetes. 总被引:27,自引:0,他引:27
Gestational diabetes (GDM) is defined as carbohydrate intolerance that begins or is first recognized during pregnancy. Although it is a well-known cause of pregnancy complications, its epidemiology has not been studied systematically. Our aim was to review the recent data on the epidemiology of GDM, and to describe the close relationship of GDM to prediabetic states, in addition to the risk of future deterioration in insulin resistance and development of overt Type 2 diabetes. We found that differences in screening programmes and diagnostic criteria make it difficult to compare frequencies of GDM among various populations. Nevertheless, ethnicity has been proven to be an independent risk factor for GDM, which varies in prevalence in direct proportion to the prevalence of Type 2 diabetes in a given population or ethnic group. There are several identifiable predisposing factors for GDM, and in the absence of risk factors, the incidence of GDM is low. Therefore, some authors suggest that selective screening may be cost-effective. Importantly, women with an early diagnosis of GDM, in the first half of pregnancy, represent a high-risk subgroup, with an increased incidence of obstetric complications, recurrent GDM in subsequent pregnancies, and future development of Type 2 diabetes. Other factors that place women with GDM at increased risk of Type 2 diabetes are obesity and need for insulin for glycaemic control. Furthermore, hypertensive disorders in pregnancy and afterwards may be more prevalent in women with GDM. We conclude that the epidemiological data suggest an association between several high-risk prediabetic states, GDM, and Type 2 diabetes. Insulin resistance is suggested as a pathogenic linkage. It is possible that improving insulin sensitivity with diet, exercise and drugs such as metformin may reduce the risk of diabetes in individuals at high risk, such as women with polycystic ovary syndrome, impaired glucose tolerance, and a history of GDM. Large controlled studies are needed to clarify this issue and to develop appropriate diabetic prevention strategies that address the potentially modifiable risk factors. 相似文献
