The mortality rate from self-harm in Iran.

BACKGROUND: Self-harm-related death is one of the most unfortunate, tragic, and regrettable types of death owing to injuries with a variety of socio-economic and cultural causes. The study aimed to determine the trend in the mortality of self-harm by sex and age at national and provincial levels in Iran over a period of 26 years. METHODS: The Iran Death Registration System (DRS), cemetery databanks in Tehran and Esfahan, and the national population and housing censuses of Iran were used for this study. Using a growth model, the population was estimated in the age groups. Incompleteness, misalignment, and misclassification in the DRS were all considered and addressed accordingly. We used a spatio-temporal and Gaussian process regression model to estimate mortality rates in children and adults. RESULTS: Over the study period, 67,670 deaths were estimated owing to self-harm across the country. The overall age-standardized mortality rate decreased from 4.32 per 100,000 (95% unit interface (UI): 3.25-5.75) to 2.78 (2.15-3.59) per 100,000 between 1990 and 2015, a reduction of approximately 35.65%. The M/F ratio was 2.03:1 with an annual percent change of -2.38% and -1.37% for women and men, respectively. The annual self-harm mortality rate was higher among individuals aged 15-24 years, as well as it was more in men during the study period. CONCLUSION: Mortality from self-harm has declined over the study period in Iran. Higher rates in men and in population aged 15-24 years, with considerable variation by province, were the distinguishing features of self-harm. Iran needs to improve monitoring through a comprehensive multisectoral strategy; and most importantly, provide timely, effective and low-cost preventive interventions.

Global prevalence of latent toxoplasmosis in pregnant women: a systematic review and meta-analysis.

BACKGROUND: Toxoplasma gondii infection, if acquired as an acute infection during pregnancy, can have substantial adverse effects on mothers, fetuses and newborns. Latent toxoplasmosis also causes a variety of pathologies and has been linked to adverse effects on pregnancy. OBJECTIVE: Here, we present results of a comprehensive systematic review and meta-analysis of the global prevalence of latent toxoplasmosis in pregnant women. DATA SOURCE: We searched PubMed, EMBASE, Web of Science, SciELO and Scopus databases for relevant studies that were published between 1 January 1988 and 20 July 2019. STUDY ELIGIBILITY CRITERIA: All population-based, cross-sectional and longitudinal studies reporting the prevalence of latent toxoplasmosis in healthy pregnant women were considered for inclusion. PARTICIPANTS: Pregnant women who were tested for prevalence of latent toxoplasmosis. INTERVENTIONS: There were no interventions. METHOD: We used a random effects model to calculate pooled prevalence estimates with 95% confidence intervals (CIs). We grouped prevalence data according to the geographic regions defined by the World Health Organization (WHO). Multiple subgroup and meta-regression analyses were performed. RESULTS: In total, 311 studies with 320 relevant data sets representing 1 148 677 pregnant women from 91 countries were eligible for inclusion in the meta-analysis. The global prevalence of latent toxoplasmosis in pregnant women was estimated at 33.8% (95% CI, 31.8-35.9%; 345 870/1 148 677). South America had the highest pooled prevalence (56.2%; 50.5-62.8%) of latent toxoplasmosis in pregnant women, whereas the Western Pacific region had the lowest prevalence (11.8%; 8.1-16.0%). A significantly higher prevalence of latent toxoplasmosis was associated with countries with low income and low human development indices (p < 0.001). CONCLUSION: Our results indicate a high level of latent toxoplasmosis in pregnant women, especially in some low- and middle-income countries of Africa and South America, although the local prevalence varied markedly. These results suggest a need for improved prevention and control efforts to reduce the health risks to women and newborns.

Trend of fatal poisoning at national and provincial levels in Iran from 1990 to 2015.

OBJECTIVES: Comprehensive and up-to-date data on fatal injury trends are critical to identify challenges and plan priority setting. This study provides a comprehensive assessment of poisoning mortality trends across Iran. STUDY DESIGN: The data were gathered from various resources, including death registration systems, cemetery databases of Tehran and Esfahan, the Demographic and Health Survey of 2000, and three rounds of national population and housing censuses. METHODS: After addressing incompleteness for child and adult death data separately and using a spatio-temporal model and Gaussian process regression, the level and trend of child and adult mortality were estimated. For estimating cause-specific mortality, the cause fraction was calculated and applied to the level and trend of death. RESULTS: From 1990 to 2015, 40,586 deaths due to poisoning were estimated across the country. The poisoning-related age-standardized death rate per 100,000 was estimated to have changed from 3.08 (95% uncertainty interval [UI]: 2.32-4.11) in 1990 to 0.96 (95% UI: 0.73-1.25) in 2015, and the male/female ratio was 1.35 during 25 years of study with an annual percentage change of -5.4% and -4.0% for women and men, respectively. The annual mortality rate was higher among children younger than 5 years and the elderly population (≥70 years) in the study period. CONCLUSIONS: This study showed that mortality from poisoning declined in Iran over the period from 1990 to 2015 and varied by province. Understanding the reasons for the differences of poisoning mortality by province will help in developing and implementing measures to reduce this burden in Iran.

Burden of neurodegenerative diseases in the Eastern Mediterranean Region, 1990-2016: findings from the Global Burden of Disease Study 2016.

BACKGROUND AND PURPOSE: The Eastern Mediterranean Region (EMR) is experiencing a demographic shift towards rapid aging at a time of political unrest. We aimed to estimate the burden of neurodegenerative disorders and its relationship with sociodemographic index in the EMR countries from 1990 to 2016. METHODS: Using data from the Global Burden of Disease Study 2016, we calculated country-specific trends for prevalence, mortality, disability-adjusted life-years (DALY), years of life lost and years lived with disability (YLD) for Alzheimer's disease/other dementias and Parkinson's disease in the EMR during 1990-2016. RESULTS: In the EMR, the age-standardized prevalence rate of Alzheimer's disease/other dementias and Parkinson's disease was estimated at 759.8/100 000 (95% uncertainty intervals, 642.9-899.9) and 87.1/100 000 (95% uncertainty intervals, 69.8-108.2) people in 2016, demonstrating 0.01% and 42.3% change from 1990, respectively. Neurodegenerative disorders contributed to 5.4% of total DALY and 4.6% of total YLD among the older EMR population (70 years of age or older in 2016). Age-standardized DALY due to Parkinson's disease were strongly correlated with the sociodemographic index level (r = 0.823, P < 0.001). The YLD:DALY ratio of neurodegenerative diseases declined during this period in the low-income but not the high-income EMR countries. CONCLUSIONS: Our findings demonstrated an increasing trend in the burden of dementias and Parkinson's disease in most EMR countries between 1990 and 2016. With aging of the EMR populations, countries should target the modifiable risk factors of neurodegenerative diseases to control their increasing burden.

Implementation of a mentored professional development programme in laboratory leadership and management in the Middle East and North Africa.

Laboratories need leaders who can effectively utilize the laboratories' resources, maximize the laboratories'capacity to detect disease, and advocate for laboratories in a fluctuating health care environment. To address this need, the University of Washington, USA, created the Certificate Program in Laboratory Leadership and Management in partnership with WHO Regional Office for the Eastern Mediterranean, and implemented it with 17 participants and 11 mentors from clinical and public health laboratories in 10 countries (Egypt, Iraq, Jordan, Lebanon, Morocco, Oman, Pakistan, Qatar, Saudi Arabia, and Yemen) in 2014. Designed to teach leadership and management skills to laboratory supervisors, the programme enabled participants to improve laboratory testing quality and operations. The programme was successful overall, with 80% of participants completing it and making impactful changes in their laboratories. This success is encouraging and could serve as a model to further strengthen laboratory capacity in the Region.

Les laboratoires ont besoin de directeurs à même d'utiliser les ressources internes de façon efficace, de maximiser leurs capacités à dépister les maladies, et d'oeuvrer pour le bien de ces établissements dans un environment de soins de santé en perpétuel changement. Pour répondre à ces besoins, l'Université de Washington [Etats-Unis], en partenariat avec le Bureau régional de l'OMS pour la Méditerranée orientale, a mis au point le Programme de certification en direction et gestion de laboratoire qui a été suivi par 17 participants et 11 mentors issus de laboratoires de santé clinique et publique dans 10 pays [Arabie saoudite, Egypte, Iraq, Jordanie, Liban, Maroc, Oman, Pakistan, Qatar et Yémen] au cours de l'année 2014. Conçu pour former les responsables de laboratoire aux compétences de direction et de gestion, le programme a permis aux participants de renforcer la qualité du dépistage et des opérations de leurs laboratoires. Le programme a été une réussite dans l'ensemble puisqu'il a été suivi jusqu'à son terme par 80% des participants et que ceux-ci ont ensuite pu mettre en place des changements réels dans leurs laboratoires. Ce succès est encourageant et pourrait servir de modèle afin de renforcer davantage encore les capacités des laboratoires dans la Région

Field emission scanning electron microscopy (FE-SEM) as an approach for nanoparticle detection inside cells.

When developing new nanoparticles for bio-applications, it is important to fully characterize the nanoparticle's behavior in biological systems. The most common techniques employed for mapping nanoparticles inside cells include transmission electron microscopy (TEM) and scanning transmission electron microscopy (STEM). These techniques entail passing an electron beam through a thin specimen. STEM or TEM imaging is often used for the detection of nanoparticles inside cellular organelles. However, lengthy sample preparation is required (i.e., fixation, dehydration, drying, resin embedding, and cutting). In the present work, a new matrix (FTO glass) for biological samples was used and characterized by field emission scanning electron microscopy (FE-SEM) to generate images comparable to those obtained by TEM. Using FE-SEM, nanoparticle images were acquired inside endo/lysosomes without disruption of the cellular shape. Furthermore, the initial steps of nanoparticle incorporation into the cells were captured. In addition, the conductive FTO glass endowed the sample with high stability under the required accelerating voltage. Owing to these features of the sample, further analyses could be performed (material contrast and energy-dispersive X-ray spectroscopy (EDS)), which confirmed the presence of nanoparticles inside the cells. The results showed that FE-SEM can enable detailed characterization of nanoparticles in endosomes without the need for contrast staining or metal coating of the sample. Images showing the intracellular distribution of nanoparticles together with cellular morphology can give important information on the biocompatibility and demonstrate the potential of nanoparticle utilization in medicine.

The state of US health, 1990-2010: burden of diseases, injuries, and risk factors.

IMPORTANCE: Understanding the major health problems in the United States and how they are changing over time is critical for informing national health policy. OBJECTIVES: To measure the burden of diseases, injuries, and leading risk factors in the United States from 1990 to 2010 and to compare these measurements with those of the 34 countries in the Organisation for Economic Co-operation and Development (OECD) countries. DESIGN: We used the systematic analysis of descriptive epidemiology of 291 diseases and injuries, 1160 sequelae of these diseases and injuries, and 67 risk factors or clusters of risk factors from 1990 to 2010 for 187 countries developed for the Global Burden of Disease 2010 Study to describe the health status of the United States and to compare US health outcomes with those of 34 OECD countries. Years of life lost due to premature mortality (YLLs) were computed by multiplying the number of deaths at each age by a reference life expectancy at that age. Years lived with disability (YLDs) were calculated by multiplying prevalence (based on systematic reviews) by the disability weight (based on population-based surveys) for each sequela; disability in this study refers to any short- or long-term loss of health. Disability-adjusted life-years (DALYs) were estimated as the sum of YLDs and YLLs. Deaths and DALYs related to risk factors were based on systematic reviews and meta-analyses of exposure data and relative risks for risk-outcome pairs. Healthy life expectancy (HALE) was used to summarize overall population health, accounting for both length of life and levels of ill health experienced at different ages. RESULTS: US life expectancy for both sexes combined increased from 75.2 years in 1990 to 78.2 years in 2010; during the same period, HALE increased from 65.8 years to 68.1 years. The diseases and injuries with the largest number of YLLs in 2010 were ischemic heart disease, lung cancer, stroke, chronic obstructive pulmonary disease, and road injury. Age-standardized YLL rates increased for Alzheimer disease, drug use disorders, chronic kidney disease, kidney cancer, and falls. The diseases with the largest number of YLDs in 2010 were low back pain, major depressive disorder, other musculoskeletal disorders, neck pain, and anxiety disorders. As the US population has aged, YLDs have comprised a larger share of DALYs than have YLLs. The leading risk factors related to DALYs were dietary risks, tobacco smoking, high body mass index, high blood pressure, high fasting plasma glucose, physical inactivity, and alcohol use. Among 34 OECD countries between 1990 and 2010, the US rank for the age-standardized death rate changed from 18th to 27th, for the age-standardized YLL rate from 23rd to 28th, for the age-standardized YLD rate from 5th to 6th, for life expectancy at birth from 20th to 27th, and for HALE from 14th to 26th. CONCLUSIONS AND RELEVANCE: From 1990 to 2010, the United States made substantial progress in improving health. Life expectancy at birth and HALE increased, all-cause death rates at all ages decreased, and age-specific rates of years lived with disability remained stable. However, morbidity and chronic disability now account for nearly half of the US health burden, and improvements in population health in the United States have not kept pace with advances in population health in other wealthy nations.

Depression and anxiety among US adults: associations with body mass index.

BACKGROUND: Obesity is associated with an increased risk of developing a variety of chronic diseases, most of which are associated with psychiatric disorders. We examined the associations of depression and anxiety with body mass index (BMI) after taking into consideration the obesity-related comorbidities (ORCs) and other psychosocial or lifestyle factors. METHODS: We analyzed the data collected from 177,047 participants (aged>or=18 years) in the 2006 Behavioral Risk Factor Surveillance System. Current depression was assessed by the Patient Health Questionnaire-8 diagnostic algorithm. Lifetime diagnoses of depression, anxiety and ORCs were self-reported. The prevalence of the three psychiatric disorders was age standardized to the 2000 US population. Multivariate-adjusted prevalence ratios were computed to test associations of depression and anxiety with BMI using SUDAAN software. RESULTS: The age-adjusted prevalence of current depression, lifetime diagnosed depression and anxiety varied significantly by gender. Within each gender, the prevalence of the three psychiatric disorders was significantly higher in both men and women who were underweight (BMI<18.5 kg/m(2)), in women who were overweight (BMI: 25-<30 kg/m(2)) or obese (BMI>or=30 kg/m(2)), and in men who had class III obesity (BMI>or=40 kg/m(2)) than in those with a normal BMI (18.5-<25 kg/m(2)). After adjusting for demographics, ORCs, lifestyle or psychosocial factors, compared with men with a normal BMI, men with a BMI>or=40 kg/m(2) were significantly more likely to have current depression or lifetime diagnosed depression and anxiety; men with a BMI<18.5 kg/m(2) were also significantly more likely to have lifetime diagnosed depression. Women who were either overweight or obese were significantly more likely than women with a normal BMI to have all the three psychiatric disorders. CONCLUSIONS: Our results demonstrate that disparities in the prevalence of depression and anxiety exist among people with different BMI levels independent of their disease status or other psychosocial or lifestyle factors.

Body mass index and headaches: findings from a national sample of US adults.

The objective was to study the cross-sectional association between body mass index (BMI) and the prevalence of severe headaches or migraines in a national sample of US adults. We used data from 7601 men and women aged > or = 20 years who participated in the National Health and Nutrition Examination Survey 1999-2002. The age-adjusted prevalence of severe headaches or migraines during the previous 3 months was 34.0, 18.9, 20.7 and 25.9% among participants with a BMI < 18.5, 18.5 to < 25, 25 to < 30 and > or = 30 kg/m(2), respectively. After adjusting for a variety of covariates in a logistic regression model, those with a BMI < 18.5 kg/m(2)[odds ratio (OR) 2.01; 95% confidence interval (CI) 1.34, 3.02] or > or = 30 kg/m(2 )(OR 1.37; 95% CI 1.09, 1.72) had a significantly elevated OR for having a headache compared with participants with a BMI of 18.5-< 25 kg/m(2). BMI is associated with the prevalence of severe headaches or migraines in a non-linear manner.

Diabetes and anxiety in US adults: findings from the 2006 Behavioral Risk Factor Surveillance System.

AIMS: Anxiety disorders may cause substantial impairment in patient functioning and well-being. Little is known about the relationship between diabetes and anxiety. We estimated the prevalence of lifetime diagnosis of anxiety in adults aged > or = 18 years with and without diabetes in the USA. METHODS: We analysed data from the 2006 Behavioral Risk Factor Surveillance System (total, N = 201 575; 20 142 with diabetes; 39.4% men, 77.9% non-Hispanic Whites, 8.1% non-Hispanic Blacks and 7.7% Hispanics; mean age 52.4 years). Diabetes and lifetime diagnosis of anxiety were self-reported. A multivariable log-binomial model was used to estimate prevalence ratios (PR) and associated 95% confidence intervals (CI) of anxiety based on diabetes status. RESULTS: The overall age-adjusted prevalence of lifetime diagnosis of anxiety was 19.5 and 10.9% in people with and without diabetes, respectively. After adjustment for educational level, marital status, employment status, current smoking, leisure-time physical activity and body mass index, people with diabetes had a 20% higher prevalence of lifetime diagnosis of anxiety than those without (PR 1.20; 95% CI 1.12, 1.30). There were no significant differences in the PR by gender (P = 0.06). However, the ratios differed significantly by age (P = 0.04) and by race/ethnicity (P < 0.01), indicating that people aged 18-29 years (PR 1.70; 95% CI 1.19, 2.43) and Hispanics (PR 1.69; 95% CI 1.33, 2.15) had a higher ratio than their counterparts. CONCLUSION: Diabetes was significantly associated with anxiety in adults in this large population-based sample, particularly in Hispanics and young adults.

[Premature ovarian failure: which approaches?]. / L'insuffisance ovarienne prématurée: quelles alternatives?

Premature ovarian failure (POF) occurs in one case of 10,000 in women below the age of 20, one case of 1000 below 30 and 1% in women before the age of 40. In 80% of POF cases, the etiology is unknown, except for Turner syndrome. Spontaneous fertility is very weak, only 3 to 10% of the patients will have natural conception. If the diagnosis is confirmed, ovarian stimulation usually fails. When fertility is desired, the alternative treatments are oocyte and/or embryo donation or adoption and "learn to be happy just in couple". Psychological management is always necessary.

Racial/ethnic variation in hypertension-related lifestyle behaviours among US women with self-reported hypertension.

Healthy lifestyles such as regular physical activity, frequent consumption of fruits and vegetables, weight control/weight loss and limited alcohol consumption are effective and recommended in hypertension control. Using data collected from a total of 131 788 female participants (aged > or = 18 years) of the 2003 Behavioral Risk Factor Surveillance System, we examined the racial/ethnic disparities in hypertension-related lifestyle behaviours in 36 770 US women with self-reported hypertension from five races/ethnicities (non-Hispanic white (29 237), non-Hispanic black (4288), Asian (445), American Indian/Alaska native (553) and Hispanic (2247)). The prevalence of hypertension varied by race/ethnicity, with the highest seen in non-Hispanic black population (36.9 versus 20.2-26.8% in other racial/ethnic groups). Of all hypertensive women, using non-Hispanic white women as the referent, we found that non-Hispanic black (adjusted odds ratio (AOR): 0.65; 95% confidence interval (CI): 0.55-0.77), American Indian/Alaska native (AOR: 0.72; 95% CI: 0.52-1.00) and Hispanic women (AOR: 0.70; 95% CI: 0.57-0.86) were significantly less likely to engage in physical activity at recommended levels; non-Hispanic black women were more likely to consume > or = 8 servings per day of fruits and vegetables (AOR: 1.70; 95% CI: 1.24-2.34), and less likely to report losing weight (AOR: 0.61; 95% CI: 0.53-0.71). In addition, Hispanic hypertensive women were significantly more likely than non-Hispanic white women to receive weight-loss advice (AOR: 1.97; 95% CI: 1.60-2.44). In contrast, non-Hispanic white women were significantly more likely than those from other races/ethnicities to consume alcoholic beverages or engage in binge drinking. Our results demonstrate that race/ethnicity is an independent predictor of lifestyle behaviours related to hypertension control among American women with hypertension.

Enhancing global capacity in the surveillance, prevention, and control of chronic diseases: seven themes to consider and build upon.

BACKGROUND: Chronic diseases are now a major health problem in developing countries as well as in the developed world. Although chronic diseases cannot be communicated from person to person, their risk factors (for example, smoking, inactivity, dietary habits) are readily transferred around the world. With increasing human progress and technological advance, the pandemic of chronic diseases will become an even bigger threat to global health. METHODS: Based on our experiences and publications as well as review of the literature, we contribute ideas and working examples that might help enhance global capacity in the surveillance of chronic diseases and their prevention and control. Innovative ideas and solutions were actively sought. RESULTS: Ideas and working examples to help enhance global capacity were grouped under seven themes, concisely summarised by the acronym "SCIENCE": Strategy, Collaboration, Information, Education, Novelty, Communication and Evaluation. CONCLUSION: Building a basis for action using the seven themes articulated, especially by incorporating innovative ideas, we presented here, can help enhance global capacity in chronic disease surveillance, prevention and control. Informed initiatives can help achieve the new World Health Organization global goal of reducing chronic disease death rates by 2% annually, generate new ideas for effective interventions and ultimately bring global chronic diseases under greater control.

Compliance with physical activity recommendations in US adults with diabetes.

AIMS: To investigate whether US adults with diabetes meet both the national and American Diabetes Association (ADA) recommendations for physical activity compared with people without diabetes, and to examine the trends of this behaviour over time. METHODS: We analysed data from large nationally representative cohorts from the 1996-2005 Behavioral Risk Factor Surveillance System. The number of participants ranged from 98 127 in 1996 to 204,977 in 2005, and the number of people with diabetes ranged from 4379 in 1996 to 13,608 in 2005. Participants were classified by their exercise status and physical activity levels. The age-standardized prevalence of physical activity participation or meeting physical activity recommendations was calculated in people with and without diabetes. RESULTS: People with diabetes participated less in physical activity (63.1-68.9 vs. 71.7-78.3%) and met physical activity recommendations less than people without diabetes (40.2-42.9 vs. 48.0-51.5% for meeting national recommendations and 38.5-41.7 vs. 46.6-49.8% for meeting ADA recommendations). The percentage of people with diabetes who participated in physical activity in the past 10 years or met physical activity recommendations in the past 5 years did not vary, whereas significantly increasing trends were observed in people without diabetes. The odds for adults with diabetes meeting physical activity recommendations were significantly lower than in adults without diabetes even after multivariate adjustment. CONCLUSION: People with diabetes were less likely to meet either national or ADA recommendations for physical activity than people without diabetes. Our results demonstrate the need for more efforts from health-care professionals to promote physical activity in people with diabetes.

Secular trends in desired weight of adults.

CONTEXT: The prevalence of overweight and obese adults in the United States is at record levels. OBJECTIVE: The primary purpose is to describe secular trends in desired weight among adults from 1994 to 2003, and secondarily, to examine the hypothetical impact of achieving desired weight on obesity prevalence. DESIGN: Data were from the Behavioral Risk Factor Surveillance System (1994, 1996, 1998, 2000, 2003), a random-digit-dialed telephone survey. SETTING: Sample included respondents from 47 states and the District of Columbia. PARTICIPANTS: Non-institutionalized adults aged 18 years or older were included (N=703 286). MAIN OUTCOME MEASURES: Primary outcome measures included reported weight and desired weight. RESULTS: Means for desired weight increased 2.3 kg between 1994 and 2003, and reported weights increased 3.9 kg. The increased trend was observed across several subgroups for age, race/ethnicity and education. Within subgroups of weight status, the trend has remained relatively stable, particularly when examined in relation to the difference between reported and desired weight as a percentage of reported body weight. Generally, overweight men desired weights approximately 4.5% less than their reported weight, and obese men desired weights approximately 15% less than their reported weight for each corresponding year. For women, approximate values of desired weight were 12% less than reported weight for overweight women and 24% less for obese women. The prevalence of obesity would decrease to 4.4% if individuals weighed their desired weight. CONCLUSIONS: Americans are shifting their desired weight upward, concomitantly with an increase in their reported body weight.

Associations between concentrations of alpha- and gamma-tocopherol and concentrations of glucose, glycosylated haemoglobin, insulin and C-peptide among US adults.

Our objective was to study the cross-sectional associations between concentrations of alpha- and gamma-tocopherol and concentrations of glucose, glycosylated haemoglobin, insulin and C-peptide among US adults. We used data for 1289 participants without self-reported diabetes who were aged > or =20 years in the National Health and Nutrition Examination Survey 1999-2000. Alpha-tocopherol concentration was inversely associated with glucose concentration (beta per mmol/l=-0.01064, SE 0.00356, P=0.004) after adjusting for age, sex, race or ethnicity, education, smoking status, concentrations of total cholesterol and triacylglycerols, systolic blood pressure, waist circumference, alcohol use, physical activity, time watching television or videos or using a computer, and use of vitamin/mineral/dietary supplements. Among 659 participants who did not report using supplements, this association was no longer significant whereas the concentration of alpha-tocopherol was inversely associated with concentration of C-peptide (beta per mmol/l=-0.01121, SE 0.00497, P=0.024). Gamma-tocopherol concentration was positively associated with concentration of glucose (beta per mmol/l=0.09169, SE 0.02711, P=0.001) and glycosylated haemoglobin (beta per mmol/l=0.04954, SE 0.01284, P<0.001), but not insulin or C-peptide. The relationships between physiologic concentrations of the various forms of vitamin E and measures of glucose intolerance deserve additional investigation.

Healthy Eating Index and C-reactive protein concentration: findings from the National Health and Nutrition Examination Survey III, 1988-1994.

OBJECTIVE: To examine whether diet quality is associated with C-reactive protein concentration. DESIGN: Cross-sectional study using data from the Third National Health and Nutrition Examination Survey (1988-1994). SETTING: Representative sample of the US population. SUBJECTS: A total of 13 811 men and women aged >/=20 y. INTERVENTIONS: We examined the cross-sectional associations between the Healthy Eating Index (HEI), a measure of diet quality according to the Dietary Guidelines for Americans, and serum C-reactive protein concentration. Dietary information was assessed using a 24-h recall. RESULTS: After adjustment for age, sex, race or ethnicity, education, smoking status, cotinine concentration, body mass index, waist-hip-ratio, aspirin use, alcohol use, physical activity level, and energy intake, HEI score was inversely associated with an elevated C-reactive protein concentration in logistic regression analysis (odds ratio per 10 unit change: 0.92; 95th confidence interval (CI): 0.86-0.99). Among the components, only the score for grain consumption was inversely associated with an elevated C-reactive protein concentration. Compared with participants in the lowest quintile of number of servings of grain consumption, the adjusted odds ratios of having an elevated C-reactive protein concentration for participants in the second, third, fourth, and fifth quintiles were 0.87 (95th CI: 0.67, 1.12), 0.85 (95th CI: 0.69, 1.06), 0.79 (95th CI: 0.65, 0.96), and 0.68 (95th CI: 0.52, 0.88), respectively. CONCLUSIONS: Grain consumption may reduce inflammation. Our findings require confirmation.

[Obstetrical prognosis improvement in patients exposed in utero to diethylstilbestrol with specific care management]. / Amélioration du pronostic obstétrical des femmes porteuses d'un utérus distilbène par une prise en charge adaptée.

OBJECTIVE: To define the interest of a specific care management of pregnancies in patients exposed in utero to diethylstilbestrol, with the intention of reducing the number of spontaneous miscarriage and prematurity. PATIENTS AND METHODS: One hundred and three pregnancies in 49 patients exposed in utero to diethylstilbestrol were followed during a 4-year study, while establishing a specific care management of pregnancies in those women. RESULTS: Spontaneous miscarriage rate was 18.5%, among which 16.5% before 15 weeks of pregnancy and 2% after 15 weeks of pregnancy. Premature birth rate was 41.9%, among which 10.8% of great premature birth (before 32 weeks of pregnancy), 13.5% of moderate premature birth (between 32 and 36 weeks of pregnancy), and 17.6% of minor prematurity (after 36 weeks of pregnancy). The patients' average delivery term was 36 +/-3.6 weeks. DISCUSSION AND CONCLUSION: As compared with the literature data, our miscarriage and prematurity rates are found to be lower. Our specific care management seems thus to be effective.
