Morpho-functional features in adolescent males under iodine deficiency of the Saratov region

An auxological study of 538 adolescent males (from 12 to 17) from different settlements of the Saratov region with various degrees of industrialization and iodine deficiency was carried out. All subjects have undergone an ultra-sound screening of thyroid volume to reveal the frequency of endemic goiter in each group. The results obtained during investigation showed the existence of deviations in the physical development of boys with goiter in skinfold thickness, body circumferences (chest, shoulder, and forearm), biacromial and biiliocristal diameters, transversal and sagittal chest diameters, body height and weight, BMI, leg length, and corpus length, all of which are greater in healthy adolescents (SD = 1.0, p = 0.000). In 46 subjects with endemic goiter, characteristics of metabolic status were investigated by the method of registration of endogenous intoxication (Malakhova, 1995). In comparison to the control group, a 1.2 times lower LAMM level in erythrocytes (p < 0.05) and 1.1 in urine (p < 0.05), and an increase by 2.3 in the LAMM level in blood plasma (p < 0.01) were detected. The relative percentage of catabolic substances exceeded the control values by 3.2 (p < 0.001). The OP level in erythrocytes is reduced by 2.2 (p < 0.01), in urine (p < 0.01) by 8.4. The OP level is higher in plasma by 3.0 (p < 0.01). The adolescents with endemic goiter have a reallocation of protein matter between erythrocytes, plasma and urine. The spectrogram of erythrocytes shows lowering metabolites on membrane frames, which testifies to the destruction of the structurally functional properties of erythrocytes, and a lowering of absorption properties in glycocalix erythrocytes.     

Iodine and zinc, but not selenium and copper, deficiency exists in a male Turkish population with endemic goiter

Although endemic goiter has been shown to have a high prevalence in Turkey, little is known about the concentration of urinary iodine, plasma selenium (Se), copper (Cu), and zinc (Zn) in these patients. We studied on 140 male patient with endemic goiter (mean age: 22.2 ± 0.19 yr) and 140 healthy male subjects (mean age: 21.8 ± 0.28 yr). Daily urinary iodine excretion was determined by the ionometric method. Plasma Se, Zn, and Cu were determined by using atomic absorption spectrometry. Daily urinary iodine excretion was found to be significantly lower in the patient group (38.7 ± 2.26 μg/d) than that of controls (50.73 ± 2.56 μg/day,p = 0.001). Plasma Zn concentrations were also found to be significantly lower in the patient group (1.04 ± 0.03 μg/mL) than that of controls (1.16 ± 0.02 μg/mL,p = 0.001). No significant difference was determined in Se and Cu concentrations between the patient and control groups. Our study shows that a moderate iodine deficiency exists in both patients with endemic goiter and control subjects, which indicates the important role of iodine deficiency in the etiopathogenesis of endemic goiter in Turkey. Zinc deficiency may also contribute to the pathogenesis of endemic goiter. However, Se and Cu do not seem to have any role in the etiopathogenesis of endemic goiter in Turkey. A community-based iodine fortification program throughout the country may be proposed to take over the problem, which also can prevent the contributing effects of other element deficiencies that occur when iodine deficiency is the prevailing factor.     

Evaluation of endemic goiter prevalence in Bulgarian schoolchildren

Iodine deficiency is a major health problem worldwide. The environment of the Balkan countries, including Bulgaria, is distinguished for its low iodine content. In 1994, the strategies for the prevention and control of iodine-deficiency disorders were actualized in Bulgaria and universal salt iodization and supplementation for the risk population groups (schoolchildren, pregnant women) were introduced. The aim of this study was to assess the effectiveness of the iodine prophylaxis in schoolchildren, living in an endemic for goiter area after the introduction of salt iodization in Bulgaria. For this purpose, the goiter prevalence and iodine status in 483 schoolchildren (274 boys and 209 girls) aged between 8 and 15 yr, living in an endemic for goiter area in Bulgaria were evaluated. Despite the normalization of iodine supply, mild iodine deficiency on the basis of goiter prevalence (16.15%) and urinary iodine excretion was found. These data indicate the need for reevaluation of the national strategy for prevention of iodine deficiency.     

Evaluation of Iron in Serum and Urine and their Relation with Thyroid Function in Female Goitrous Patients

In many developing countries, women are at high risk of goiter and iron deficiency anemia (IDA). Iron deficiency adversely affects thyroid metabolism and may decrease the efficiency of thyroid hormones in areas of endemic goiter. The aim of the present study was to compare the level of iron (Fe) in biological samples (serum and urine) and serum thyroid hormones, thyroid stimulating hormone (TSH), free triiodothyronine (FT3), and free thyroxin (FT4) of goitrous female patients (GFPs; n = 69) with those of nongoitrous women as control subjects (n = 117), age range 21–45 years. The biological samples were analyzed for Fe concentration using flame atomic absorption spectrophotometer, prior to microwave-assisted wet acid digestion. The validity and accuracy of the method was checked by the certified sample and with those obtained by conventional wet acid digestion method on the same CRM and real samples. The overall recoveries of Fe in serum and urine were found in the range of 97.2–98.6% of certified values. The results of this study showed that the mean values of Fe in serum and urine samples of GFPs were significantly reduced as compared to control subjects (p = 0.002 and p = 0.015, respectively). The mean values of FT3 and FT4 were found to be lower in GFPs than in the age-matched healthy control women; in contrast, high mean values of TSH were detected in GFPs (p = 0.003). There was a positive correlation between serum Fe concentration and TSH (r = 0.85, p = 0.01), FT3 (r = 0.95, p = 0.003), and FT4 levels (r = 0.98, p = 0.007) in GFPs. It was observed that iron deficiency is prevalent in GFPs, so the need of Fe supplementation will be required to improve the efficacy of thyroid metabolism in goitrous women.     

Measurement of Phenolic Environmental Estrogens in Women with Uterine Leiomyoma

Objectives

To investigate the effect of phenolic environmental estrogens on uterine leiomyoma from the perspective of clinical epidemiology.

Methods

Urine and blood samples were collected from Han women with uterine leiomyoma and women without uterine leiomyoma, living in Nanjing, China, between September 2011 and February 2013. A total of 156 urine samples and 214 blood samples were collected from the uterine leiomyoma group and 106 urine samples and 126 blood plasma samples from the control group. Bisphenol A (BPA), nonylphenol (NP) and octylphenol (OP) concentrations were determined by solid-phase extraction (SPE) coupled with liquid chromatography-tandem mass spectrometry (HPLC-MS/MS).

Results

Phenolic environmental estrogens in the uterine leiomyoma and control groups were compared based on: gravida>3 and gravida ≤ 3. In participants with gravida>3, urine OP concentration was significantly (P<0.05) higher in the uterine leiomyoma group than in the control group. In participants with gravida ≤ 3, urine NP concentration was significantly (P<0.05) higher in the uterine leiomyoma group compared to controls. Despite obstetric history, urine BPA mean exposure concentration was significantly (P<0.05) different between uterine leiomyoma group and control group. The urine BPA concentration was not significantly (P>0.05) different between gravida>3 and gravida ≤ 3 patients. There was no significant (P>0.05) difference in plasma concentrations of BPA, OP and NP between the leiomyoma group and control group. Mean exposure concentration and range of distribution of BPA, OP and NP plasma concentration differed between the uterine leiomyoma and control group.

Conclusion

Exposure level of phenolic environmental estrogens in human was related with leiomyoma tumorigenesis.     

GC-FPD measurement of urinary dialkylphosphate metabolites of organophosphorous pesticides as pentafluorobenzyl derivatives in occupationally exposed workers and in a general population in Shanghai (China)

Measurement of organophosphorus (OP) pesticide metabolites in human biological fluids is an important biomarker of pesticides exposure. We measured the urinary excretion of OP pesticide metabolites to evaluate occupational and non-occupational exposure to OP pesticides in the Chinese population in Shanghai (Eastern China). We collected urine samples from 30 exposed workers in a dimethoate emulsion packing division and from 60 healthy adults without any report of occupational exposure. DMP, DMTP, DMDTP, DEP, DEDP and DEDTP were measured by GC-FPD after derivatization with pentafluorobenzyl bromide. The LOQ values (1 mL urine) were 2.0 μg/L for DMP and DETP, 4.0 μg/L for DEP and DEDTP, 8.0 μg/L for DMDTP, and 10.0 μg/L for DMTP. Dimethyl phosphates were detected in the majority of the urine samples, i.e., 90–100% in the exposed group and 80–87% in the control group. The concentration of the urinary diethyl phosphates DEP and DETP was above the LOQ values in 40 and 20% of samples for the exposed group, and in 50 and 30% of the samples for the control group, respectively. DEDTP was not detectable in the urine samples except for a post-shift exposed worker (detection frequency, 6.7%). Median creatinine-adjusted values (μg/g cr.) for DAP in Chinese with pre-shift, post-shift and without occupational exposure to OP were 316, 584 and 170 for DMP, below LOQ, 115 and 114 for DEP, 840, 1730 and 693 for DMTP, and 255, 756 and 135 for DMDTP, respectively. In all subjects, the highest excretion levels were found for DMTP. Several OP pesticide metabolites were frequently detected in urine samples of both populations studied.     

Association between serum placental growth factor and vascular endothelial function in hyprtensive disorders complicating pregnancy

Hypertensive disorders complicating pregnancy (HDCP) is a systemic disease among pregnant women. Therefore, the prevention and prediction of hypertension during pregnancy are critical. This study aimed to clarify whether the vascular endothelial function of women with gestational hypertension was linked to placental growth factor. A total of 200 pregnant women were enrolled in our study and subsequently divided into two groups: the HDCP group and the normal pregnancy controls. The levels of serum placental growth factor, as well as plasma endothelin-1 and nitric oxide, between the two groups were measured. In addition, the endothelial function indexes, including pressure-strain elasticity coefficient (EP), the common carotid stiffness index (β), arterial compliance, single-point pulsed-wave velocity, and augment index (AI) of bilateral common carotid arteries, were compared between the HDCP and control groups using the echo tracking technique. In our study, the level of placental growth factor in the HDCP group was significantly lower than the control group. Furthermore, our results clarified that endothelin-1 increased while nitric oxide decreased in the HDCP group compared with the control group. On the other hand, we found that EP, β, pulsed-wave velocity and augment index values were significantly higher in the HDCP group than in the control group (P < 0.001). However, the value of arterial compliance was significantly decreased in patients of the HDCP group compared with the control group (P < 0.001). In conclusion, the association between serum placental growth factor and vascular endothelial function in HDCP could serve as a more accurate predictive factor of pregnant hypertension.     

The patterns of changes in the electrohysterogram amplitude characteristics in healthy pregnant women during the third trimester

The patterns of changes in the amplitude characteristics of the bioelectrical activity of the uterus were studied on the basis of the external multichannel electrohysterography data in healthy pregnant women with physiological pregnancy at weeks 28 to 40 of gestation using electrophysiological methods. Three groups of women were identified, according to the term of pregnancy. The first group included 12 women at 26–28 weeks of gestation; the second group, 49 women at 29–37 weeks of gestation; and the third group, 48 women at 38–40 weeks of gestation. The preliminary norms of the electrohysterogram amplitude characteristics were obtained. The average electrohysterogram amplitude was revealed to increase with the term of the pregnancy.     

Pattern of bone markers during pregnancy and their changes after delivery

OBJECTIVE: To investigate whether bone resorption markers change during pregnancy and lactation, and how they are correlated with human placental lactogen (hPL) and PRL. SUBJECTS: Young women before pregnancy, during pregnancy and during a 12-month post-delivery period (study group; n = 22); and age- and weight-matched normal cycling women (control group; n = 22) for a 20-month-period participated in the study. RESULTS: In the study group, women both during pregnancy (from the 8th up to the 38th week) and during a 6-month period of lactation, pyridinoline and deoxypyridinoline urinary levels were significantly higher than those of pre-pregnancy and control women. They returned to basal values at the 12th post-delivery month. During pregnancy there were early and late peak increases, at the 8th and 32nd week, respectively. At the 32nd, 34th, 36th and 38th week of pregnancy, pyridinoline and deoxypyridinoline urinary values were significantly correlated with hPL serum levels. CONCLUSIONS: During pregnancy the maternal bone resorption seems to vary critically at early and late stages. A complete reversal of these variations seems to occur after lactation. Further studies could evaluate if changes in placental function are capable of differently interfering with maternal bone resorption.     

Sp1 polymorphism in collagen I α1 gene is associated with osteoporosis in lumbar spine of Mexican women

The Sp1 binding site polymorphism in collagen type I alpha 1 gene (COLIA1) has been associated with osteoporosis (OP) and bone mineral density (BMD). The aim of this study was to explore the association of this polymorphism with OP and BMD in the Mexican population by polymerase chain reaction and restriction fragment length polymorphism (PCR–RFLP) procedure. Allelic and genotypic frequencies from the Sp1 polymorphism were determined in 100 women with OP, 100 women without OP and 500 subjects from general Mexican population (GMP). Distribution of Sp1 polymorphism was in Hardy–Weinberg equilibrium. In spite of population structure due to racial mix in Mexican population, associations with OP were demonstrated. The frequency of “s” allele was significantly higher in women with OP (35%) than in women without OP (11%; P < 0.00001). Interestingly, “ss” genotype, was exclusive of women with OP and was associated with low BMD (0.588 ± 0.077 g/cm²) in contrast to “SS” genotype (0.733 ± 0.039 g/cm²; P = 0.0001). This work confirms the association of Sp1 polymorphism with low BMD and OP in Mexican population and make sure to use Sp1 as a genetic marker for OP in our population.     

Changes of total content of serum magnesium in elderly Chinese women with osteoporosis

Objective To explore whether the serum levels of magnesium (Mg) and calcium (Ca) differ between osteoporotic and nonosteoporotic elderly Chinese women. Methods Using WHO classification criteria based on bone mineral density (BMD), general healthy Chinese women older than 65 yr were classified as osteoporosis (OP), osteopenia, and normal group according to the T-score of the femur neck. Then their physical characteristics, serum levels of magnesium (sMg), calcium (sCa), and other biochemical measurements were analyzed. Results Altogether, 324 subjects were included in the final analysis with 77 in OP, 137 in osteopenia, 110 in normal group. The level of sMg in women with OP is significantly higher (0.91±0.11 mmol/L) than both the osteopenia (0.88±0.09 mmol/L) and the normal (0.87±0.08 mmol/L) even after being adjusted for both age and body mass index (BMI), which might result from potentially low levels of sCa. sMg inversely related to sCa in subjects with OP (r=−0.240, p=0.038), whereas the total levels of sCa and sMg kept relatively steady. Conclusion High content of sMg and potentially low content of sCa could be a feature of the serum profile of elderly Chinese women with OP, the clinical significance of which needs further elucidation. Supplementation of Mg for elderly Chinese women with OP did not appear to be necessary.     

GDM患者综合性干预的应用研究

本研究旨在探讨综合性干预对妊娠期糖尿病(gestational diabetes mellitus, GDM)孕妇妊娠结局及新生儿并发症的影响。本研究选取130例妊娠晚期糖尿病患者随机分组,对照组患者给予常规护理,试验组患者实施综合性干预,观察两组患者血糖指标、妊娠结局、新生儿健康状况、血脂水平差异。实验结果显示,试验组空腹血糖(fasting blood glucose, FBG)、糖化血清蛋白(glycosylated serum pritein, GSP)、血管细胞黏附分子-1(CD106)明显低于对照组(p<0.05);试验组早产、剖宫产、羊水过多、产后出血、胎儿窘迫现象明显低于对照组(p<0.05);试验组患者新生儿窒息、巨大儿、新生儿低血糖、新生儿高胆红素血症显著低于对照组(p<0.05);治疗后实验组患者TC (5.63±1.52) mmol/L,TG (3.18±0.45) mmol/L,LDL-C (3.15±0.64) mmol/L显著低于对照组(p<0.05)。研究表明,针对妊娠晚期糖尿病患者应用综合性干预可改善患者血糖水平、血脂水平、妊娠结局,降低巨大儿发生率,具有临床应用推广价值。     

Soluble fibrin and D-dimer at normal pregnancy and pregnancy with risk of miscarriage

ELISA for soluble fibrin (SF) quantification has been elaborated on the basis of our fibrin-specific monoclonal antibodies (mAb). Epitope for these mAb is localized in fibrin fragment Bbeta118-134. The method was used on the blood plasma of healthy pregnant women (control group) and pregnant women with the risk of fetal loss (RFL). The increased mean values of SF concentrations were observed at pregnancy with RFL as compared to the normal pregnancy at the terms from 4 to 24 weeks (17.87 +/- 3.15 mkg/ml and 9.03 +/- 1.58 mkg/ml accordingly, p < 0.05). A weak negative correlation between SF concentration and pregnancy term was found at RFL (r = -0.201, n=35), while there was no correlation between these variables in control group (r = 0.004, n=28). The mean values of SF concentration estimated by semiquantitative test (by phosphates salting out of SF) were also higher at the pregnancy with RFL as compared to the normal pregnancy. However, the absolute values of SF concentrations determined by salting out method were essentially higher than in the case of ELISA. Immunoblot analysis with mAb 2d-2a (epitope for which in fibrin molecule encompasses peptide bond Bbeta14-15), showed that the main molecular component of SF at normal pregnancy and RFL was oligomeric fibrin desAA with possible incorporation of fibrinogen and/or fibrin desA which was not stabilized by factor XIIIa. D-dimer concentrations determined in blood plasma samples of pregnant women by ELISA varied in the range of 1-224 ng/ml at the pregnancy period from 4 to 37 weeks. There was positive correlation between D-dimer concentration and pregnancy term both at normal pregnancy and pregnancy with RFL (r = 0.765, n=33 and r = 0.712, n=44 correspondingly). The mean values of D-dimer concentration at various terms of normal pregnancy and pregnancy with RFL did not vary considerably. Thus SF but not D-dimer quantification may give useful diagnostic information at the pregnancy with RFL.     

血清妊娠相关血浆蛋白A在诊断异常妊娠中的临床意义

目的:探讨血清妊娠相关血浆蛋白A(PAPP-A)在诊断异常妊娠中的临床意义,分析其与异常妊振的关系。方法:选取299例5~13周的正常早孕妇为正常早孕组,同期选取稽留流产86例,先兆流产54例,异位妊娠76例为异常妊娠组,用酶联免疫吸附试验(ELASA)测定两组受试者的血清PAPP-A水平,分析两组受试者各个孕周内的血清PAPP-A水平的差异。结果:稽留流产孕妇在各个孕周内(9~13周)的血清PAPP-A水平显著低于同孕周内正常早孕孕妇(t值分别为9.500,8.113,3.511,9.538,8.504,P值均0.05);稽留流产孕妇总的平均血清PAPP-A水平亦低于常早孕孕妇(t=3.651,P值均0.05);异位妊娠孕妇在各个孕周内(9~13周)的血清PAPP-A水平显著低于同孕周内正常早孕孕妇(t值分别为7.976,9.030,9.941,11.625,14.079,12.569,P值均0.05),异位妊娠孕妇总的平均血清PAPP-A水平亦低于常早孕孕妇(t=28.168,P值均0.05);先兆流产孕妇(除孕8周)与正常早孕妊娠血清PAPP-A水平比较无显著统计学意义。结论:血清PAPP-A水平在异常妊娠如异位妊娠、稽留流产中显著降低,可作为诊断异位妊娠、稽留流产及先兆流产辅助诊断的生物学指标。     

The nutritional consequences of pregnancy sickness

The purpose of this paper is to assess Profet’s (1992) and others’ hypothesis that nausea and vomiting in pregnancy (NVP) is adaptive. A number of studies have found an association between NVP and a decreased risk for early fetal loss (<20 weeks). It is assumed that the adaptive benefits of improved survivorship associated with NVP outweigh the minimal nutritional consequences. However, in populations that experience marginal levels of nutrition, NVP may have important nutritional consequences. To test these potential consequences, a study on NVP, nutritional status, and pregnancy outcome was conducted among Turkana pastoralists, who experience seasonal and chronic nutritional stress. Interviews and anthropometric assessments were conducted on 68 pregnant Turkana women of Kenya during a 1993–1994 field season. The results from the case study suggest that women who experience NVP do encounter nutritional consequences in the later stages of pregnancy and are more likely to experience poor pregnancy outcomes. These results suggest that NVP may not be adaptive in all environmental settings, particularly among marginally nourished populations. Financial support for the Turkana study was provided by a dissertation fellowship from The Population Council, Wenner-Gren Foundation, and NSF grants BNS-8718477, and DBS-9207837. Ivy L. Pike, Ph.D., is an Assistant Professor of Anthropology at Ohio State University. Her research interests include the evolutionary and ecological context of health, nutrition, and reproduction. She has conducted research among Turkana women of Kenya and is initiating a project among the Iraqw, an agro-pastoral population of Tanzania.     

Profil des hormones thyroïdiennes chez les femmes enceintes : analyse de 125 cas à l’hôpital général de Yaoundé

This study was aimed at determining the evolution and the kinetics of thyroid hormones in a sub-population of pregnant women in Cameroon. We carried out a prospective study (from January 2005 to January 2006) on 125 consenting pregnant women at the Yaoundé General Hospital. Clinical and gyneco obstetric data with the gestational age were noted on a pre-designed questionnaire. Blood samples were drawn for serum assay of thyroxin (T4), triiodothyronine (T3) and thyroid stimulating hormone. The results were read with the “Oakfield health care” Gamma – 12 counter using the RIASTAT software. These patients, divided into four groups consisted of: 32 non pregnant women in the control group; 33 pregnant women in the first trimester; 30 pregnant women in the second trimester and 30 at the third trimester. The mean serum levels of T3 and T4 were relatively high in all pregnant women (irrespective of the gestational age) than in the control group. Serum levels of T3 and T4 were raised the first trimester with and progressively reduced in 2nd and 3rd trimester. On otherhand, TSH levels progressively increased as from the 2nd trimester to attain a maximum in the 3rd trimester. We can therefore conclude that blood levels of thyroid hormone as well as TSH vary during pregnancy and differ in titres with respect to the gestation age.     

Status of selenium and antioxidant enzymes of goitrous children is lower than healthy controls and nongoitrous children with high iodine deficiency

In order to investigate the relations of iodine deficiency and/or goiter with selenium (Se) and antioxidant enzyme (AOE) status, we determined the relevant parameters of goitrous high school children living in an endemic goiter area of Turkey. Subjects were selected by a simple random sampling technique after screening the whole population of the high schools of two towns by neck palpation. The results of the goitrous group (n = 48, aged 15-18 yr) were compared with those of nongoitrous control children (n = 49) from the same populations, and with an outside control group (n = 24) from a lower-goiter-prevalence area. The overall prevalence of goiter was 39.6% in the high school population of the area. Activities of erythrocyte AOE (glutathion peroxidase, catalase, and superoxide dismutase) and concentrations of plasma and erythrocyte Se and urinary iodine were found to be significantly lower in goitrous children than both in-region and out-region of the control groups. When the whole study group was reclassified according to the severity of iodine deficiency, it was found that the AOE and Se status of those control children without goiter but with high iodine deficiency was significantly higher than goitrous children, although they did not differ from nondeficient control group. This might be the result of the possibility that goitrous children are exposed of oxidative stress, which may introduce alterations to the antioxidant defense system and/or the antioxidant status is relatively lower in goitrous children than those children who are highly iodine-deficient but did not develop goiter. The results of this study seem to support the view that the risk of goiter development may be higher in highly iodine-deficient children with lower enzymatic antioxidant and Se status.     

Low Osteoporosis Treatment Initiation Rate in Women after Distal Forearm or Proximal Humerus Fracture: A Healthcare Database Nested Cohort Study

Treatment initiation rates following fragility fractures have often been reported to be low and in recent years numerous programs have been implemented worldwide to increase them. This study aimed at describing osteoporosis (OP) treatment initiation in a representative sample of women who were hospitalized for a distal forearm fracture (DFF) or proximal humerus fracture (PHF) in 2009–2011 in France. The data source was a nationwide sample of 600,000 individuals, extracted from the French National Insurance Healthcare System database. All women aged 50 years and older who were hospitalized for a DFF or PHF between 2009 and 2011 and who had not received any OP treatment in the preceding 12 months were included in a retrospective cohort study. OP treatments initiated during the year following the fracture were analyzed. From 2009 to 2011, 729 women were hospitalized for a DFF or a PHF and 284 were on OP treatment at the time of the fracture occurrence. Among the 445 women who had no prevalent OP treatment, 131 (29.4%) received supplementation treatment only (vitamin D and/or calcium) and 42 (9.4%) received a pharmacologic OP treatment in the year following their fracture. Pharmacological OP treatments included bisphosphonates (n = 21), strontium ranelate (n = 14), hormone replacement therapy (n = 4), or raloxifene (n = 3). General practitioners prescribed 75% of initial OP treatments. Despite the guidelines published in 2006 and the numerous initiatives to promote post-fracture OP treatment, OP treatment initiation rate in women who were hospitalized for a fragility fracture remained low in 2009–2011 in France.

Serum Selenium Concentrations Correlate Significantly with Inflammatory Biomarker High-sensitive CRP Levels in Hungarian Gestational Diabetic and Healthy Pregnant Women at Mid-pregnancy

Selenium is an essential trace element and a component of various enzymes with antioxidant functions. High-sensitive C-reactive protein (hsCRP) is an early indicator of increased lipid peroxidation. The serum selenium concentration, lipid parameters, and hsCRP values of gestational diabetic pregnant women (GD), control pregnant women (CP), and healthy nonpregnant controls (HC) were compared. Blood was taken between the 24th and the 28th week of pregnancy when the oral glucose tolerance test was performed. Selenium concentration was determined by atomic absorption spectrometry after hydride generation. HsCRP was measured by immunturbidimetry. HC had significantly higher serum selenium concentrations than GD and CP women (HC = 77.4 ± 14.82, GD = 51.7 ± 11.62, and CP = 40.5 ± 8.03 μg/l, respectively). HsCRP values of both GD and nondiabetic pregnant women were significantly higher compared to controls. Significant negative correlations were found between serum selenium and total cholesterol, low-density lipoprotein cholesterol, and hsCRP values indicating that low selenium levels are associated with increased lipid peroxidation. Serum selenium concentrations of Hungarian pregnant women are low compared to internationally published data.
