OBJECTIVE: To determine the prevalence of HIV infection among pregnant women in Newfoundland. DESIGN: Anonymous unlinked seroprevalence study. SETTING: Newfoundland. PATIENTS: A total of 14911 women receiving prenatal care or undergoing an abortion, representing nearly all pregnancies in Newfoundland from Nov. 1, 1991, to Oct. 31, 1993. OUTCOME MEASURES: HIV antibody status, as determined by enzyme immunoassay of leftover serum samples (initially obtained for routine screening) and confirmation of reactive samples by the Western blot technique, health region of residence, and age group. RESULTS: Of the 14911 serum samples 13 were positive for HIV, for an overall crude prevalence rate of 1 per 1147 or 8.7 per 10000 pregnant women (95% confidence interval [CI] 4.7 to 14.9). Seven of the positive samples were from women residing in the Eastern Health Region of the province, for a crude prevalence rate of 1 per 376 or 26.6 per 10000 pregnant women (95% CI 10.7 to 54.8) for that region. All women found to be HIV positive were 15 to 29 years of age, the peak prevalence (20.8 per 10000 pregnant women [95% CI 9.5 to 39.4]) was observed among those 20 to 24 years. CONCLUSIONS: The overall prevalence rate of 8.7 per 10 000 pregnant women in Newfoundland is the highest provincial rate recorded among those from similar studies in Canada. Although it may be concluded that there are an estimated 125 HIV-positive women of childbearing age in Newfoundland (95% CI 67 to 213), the age-adjusted estimate is 84 (95% CI 36 to 131). This study provides an independent confirmation of an outbreak of HIV infection among women in the Eastern Health Region of the province. 相似文献

Periodic limb movements during sleep (PLMS) are identified as a common finding in patients with restless legs syndrome (RLS). Although PLMS are observed in more than 80% of RLS patients in Western countries, little is known about Asian RLS patients and no data are available about Japanese patients. This cross-sectional study aimed to investigate ethnic differences in clinical information and polysomnographic variables including PLMS between Austrian and Japanese RLS patient undergoing nocturnal polysomnography (n-PSG). One hundred Austrian and 139 Japanese consecutive patients diagnosed with RLS who underwent n-PSG were included [Austrian 54.5 ± 13.6 years, 40 females (40%); Japanese 50.2 ± 18.9 years, 88 females (63.3%)]. Medical records and n-PSG data were reviewed retrospectively. Epidemiological, clinical and n-PSG variables were compared between the two groups. Rate of patients with PLMS ≥ 5/h and those with PLMS ≥ 15/h were higher in Austrian than in Japanese RLS patients (80.0 vs. 56.1%, P < 0.001; 55.0 vs. 41.7%, P = 0.043). Accordingly, Japanese RLS patients showed lower PLMS index than Austrian patients (21.3 vs. 33.6/h, P = 0.008). Japanese RLS patients showed higher female predominance, lower BMI, lower systolic/diastolic blood pressure, lower ferritin level and higher International restless legs syndrome severity scale than Austrian patients. None of these variables were associated with PLMS in both groups. Japanese RLS patients showed significantly lower comorbidity rate and lower indices of PLMS compared to Austrian RLS patients. This cross-sectional study on ethnic differences in PLMS in patients with RLS may provide a bridge to a future genetic comparative study between European and Asian RLS patients. 相似文献

Restless legs syndrome is a curious neurological disorder of unknown aetiology. A new study has found that Drosophila mutants in the fly homologue of a human gene, BTBD9, that has been implicated as a risk factor for restless legs display important features of the syndrome. 相似文献

In recent years, sleep abnormalities have increasingly been observed in patients with movement disorders. During sleep, most patients with Parkinson's disease also exhibit the movements characteristically seen during the wake period. Movement activity during sleep may impair sleep quality and lead to daytime sleepiness and reduced quality of life. Disordered REM sleep with enhanced muscle tone is common in patients with neurodegenerative disease, and may precede the clinically evident symptoms of Parkinson's disease by years. Sleep disorders in patients with Parkinson's disease are common, and require the application of individual treatment strategies. A further frequent disorder primarily classified as a sleep disorder (dyssomnia) is the restless legs syndrome (RLS), which is closely related to the nocturnal periodic limb movement disorder and affects up to 15% of the population. The present review focuses on nocturnal motor activity and sleep in Parkinson's disease and RLS. 相似文献

BACKGROUND: The prevalence of gestational diabetes mellitus has been reported to vary widely in aboriginal populations. Most of the data have come from the United States. To help determine the extent of gestational diabetes in Canada''s aboriginal population, the authors assessed the prevalence in a population of Cree women in northern Quebec. METHODS: A cross-sectional study was conducted using the National Diabetes Data Group (NDDG) criteria. Information was obtained from patient charts on pregnancies between January 1995 and December 1996 among women residing in 9 Cree communities in the eastern James Bay region of northern Quebec. Women who were not Cree, had pre-existing diabetes, had spontaneous abortion or were receiving glucocorticoid treatment were excluded. RESULTS: Data on 654 pregnancies that met the inclusion criteria were available. Results of the screening oral glucose challenge test were available for 579 of the pregnancies; the remaining 75 were excluded. The mean gestational age at screening was 28.3 (standard deviation 2.6) weeks. The prevalence of gestational diabetes was 12.8% (74/579) (95% confidence interval [CI] 10.1%-15.5%). The prevalence in the inland communities was twice as high as that in the coastal communities (18.0% v. 9.3%, p = 0.002). Women with gestational diabetes or impaired glucose tolerance tended to be older, have had more pregnancies, weigh more before pregnancy and have heavier babies than those with a normal glycemic status. INTERPRETATION: The prevalence of gestational diabetes among James Bay Cree women in northern Quebec is twice as high as that among women in the general North American population and the second highest reported in an aboriginal group worldwide. 相似文献

Background Restless legs syndrome (RLS) is a neurological disorder with a lifetime prevalence of 3-10%. in European studies. However, the diagnosis of RLS in primary care remains low and mistreatment is common. Methods The current article reports on the considerations of RLS diagnosis and management that were made during a European Restless Legs Syndrome Study Group (EURLSSG)-sponsored task force consisting of experts and primary care practioners. The task force sought to develop a better understanding of barriers to diagnosis in primary care practice and overcome these barriers with diagnostic and treatment algorithms. Results The barriers to diagnosis identified by the task force include the presentation of symptoms, the language used to describe them, the actual term "restless legs syndrome" and difficulties in the differential diagnosis of RLS. Conclusion The EURLSSG task force reached a consensus and agreed on the diagnostic and treatment algorithms published here. 相似文献

Spexin (SPX) is a novel biomarker abundantly expressed in several animal and human tissues implicated in food intake and glucose control, respectively. As new roles for SPX are emerging, the present study explored for the first time, the associations of SPX to several cardiometabolic indices and inflammatory markers in pregnant women, a demographic not yet investigated with respect to SPX. A total of 117 Saudi women subdivided to those with gestational diabetes mellitus (GDM) (N?=?63) and those without (N?=?54) were included in this cross-sectional study. Anthropometry, glycemic, lipid, vitamin D, adipocytokines and inflammatory markers were measured consecutively at baseline and after the 2nd and 3rd trimesters. Age- and BMI adjusted comparisons revealed that levels of SPX were not significantly different in pregnant women with and without GDM. In all subjects, circulating levels of SPX showed modest associations with glucose (R?=?0.18; p?=?.08) and HOMA β (R?=??0.19; p?=?.09) as well as significant positive associations with total cholesterol (R?=?0.25; p?=?.02), LDL-cholesterol (R?=?0.25; p?=?.02), 25(OH)D (R?=?0.22; p?=?.04), albumin (R?=?0.30; p?<?.01) and IL1β (R?=?0.41; p?<?.01). Stepwise regression analysis also suggested that IL1β, leptin and albumin were the significant predictors of SPX. In summary, SPX levels modestly affect glucose and insulin sensitivity in pregnant women but is not associated with GDM and obesity. The significant association of SPX to ILβ warrants further investigation as to the role of SPX in immune modulation. 相似文献

Previous studies have suggested that there is a genetic basis to restless legs syndrome (RLS) development. Occurrence of antipsychotic-induced RLS could also be due to differences in genetic susceptibility. We investigated whether CLOCK and NPAS2 gene polymorphisms are associated with RLS in schizophrenic patients on antipsychotics because RLS symptoms usually manifest during the evening and night. We assessed symptoms of RLS in 190 Korean schizophrenic patients on antipsychotics and divided the subjects into two groups according to the International Restless Legs Syndrome Study Group diagnostic criteria: (i) subjects who met all the criteria and (ii) the remaining subjects who did not meet all the criteria. We found a significant difference in the number of subjects with different genotype and allele carrier frequencies for the CLOCK gene (rs2412646) between the two groups ( p?=?0.031 and 0.010, respectively). Distribution of CLOCK haplotypes (rs2412646–rs1801260) was significantly different between schizophrenic patients with and without RLS ( p?=?0.021). However, the distributions of allelic, genotypic, and haplotypic variants of NPAS2 (rs2305160 and rs6725296) were not significantly different between the two groups. Our results suggest that CLOCK polymorphisms are associated with increased susceptibility of schizophrenic patients to RLS. We hypothesize that RLS in schizophrenia patients treated with antipsychotics may be a very mild akathisia that manifests during the night and is under control of circadian oscillation. 相似文献

Background Low doses of dopamine agonists (DA) and levodopa are effective in the treatment of restless legs syndrome (RLS). A range of
impulse control and compulsive behaviours (ICBs) have been reported following the use of DAs and levodopa in patients with
Parkinson's disease. With this study we sought to assess the cross-sectional prevalence of impulse control behaviours (ICBs)
in restless legs syndrome (RLS) and to determine factors associated with ICBs in a population cohort in Germany. 相似文献

One hundred and seventy four patients suffering from the restless legs syndrome were examined in a double blind, between patient, placebo controlled study in general practice for five weeks to investigate the effects of carbamazepine and placebo on the syndrome. The syndrome was more common among middle aged women with relatively low systolic blood pressure. The median haemoglobin concentration was about average for the population, but the severity of the symptoms seemed to increase with decreasing concentrations of haemoglobin. Both placebo and carbamazepine showed a significant therapeutic effect (p less than 0.01). Carbamazepine was significantly more effective than placebo (p less than or equal to 0.03). The significant therapeutic effect of placebo in restless legs showed that only double blind controlled trials can confirm the efficacy of suggested treatments. 相似文献
