Using diagnostic codes for treating thyroid disorders and αHHV infections as proxies for biologic/clinic outcomes, we queried a large, comprehensive hospital data base to construct two patient cohorts: Cohort 1 was comprised of patients receiving TH diagnoses over a twelve-year period, and Cohort 2 was composed of patients not receiving TH diagnoses during this period.

This result suggested that patients with αHHV diagnosis have higher chances to have TH disorders. Additional investigation revealed that female were at higher/significant probability to have both TH and αHHV diagnosis, indicating a link of αHHV reactivation to a complex hormonal profile difference between genders. Our observation indicated that female patients of 21 years of age and above exhibited a very high incidence (OR of 3.40, p < 0.001) compared to the male groups (OR of 1.91, p < 0.05), indicating the possibility that hormonal alteration in females maybe transient but robust and can lead to αHHV reactivation more often than the males.</p><p><strong>Conclusion: </strong>These results indicated that TH dysfunction may have implication in αHHV pathogenesis and females exhibited much higher probability to suffer αHHV reactivation due to TH disruption.

Since perinatal testosterone (T) secreted by the developing testes masculinizes cortical and hippocampal structures and the behaviors regulated by these brain regions, we hypothesized that sexually dimorphic expression of specific selected genes in these areas might be regulated by T during early development. METHODS To test our hypothesis, we treated timed pregnant female mice daily with vehicle or testosterone propionate (TP) starting on embryonic day 16 until the day of birth. The cortex/hippocampus was collected from vehicle- and TP-treated, male and female neonatal pups. Total RNA was extracted from these brain tissues, followed by RT-qPCR to measure relative mRNA levels of seven sex chromosome genes and three autosomal genes that have previously showed sex differences. RESULTS The effect of prenatal TP was confirmed as it stimulated Dhcr24 expression in the neonatal mouse cortex/hippocampus and increased the anogenital distance in females. We found a significant effect of sex, but not TP, on expression of three Y-linked (Ddx3y, Eif2s3y, and Kdm5d), four X-linked (Eif2s3x, Kdm6a, Mid1, and Xist), and one autosomal (Klk8) genes in the neonatal mouse cortex/hippocampus. CONCLUSION Although most of the selected genes are not directly regulated by prenatal T, their sexually dimorphic expression might play an important role in the control of sexually differentiated cognitive and social behaviors as well as in the etiology of sex-biased neurological disorders and mental illnesses.","PeriodicalId":17132,"journal":{"name":"Journal of steroids & hormonal science","volume":"200 1","pages":"1000139"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76969577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Plasma CRP increases dramatically after severe trauma, bacterial infection and inflammation. The hsCRP accurately and sensitively measures basal levels of CRP, including in the areas of increased risk of developing myocardial infarction. Tobacco smoking has also been indicated to influence pregnancy outcomes and infertility . Methods: We examined the associations between smoking, circulating hsCRP, and steroid hormone levels in healthy, non-pregnant women of reproductive age. Serum hsCRP concentrations were analyzed using immunoturbidimetry. Based on cotinine levels and self-questionnairres, the women were divided into three separate groups of smokers, non- smokers and passive smokers (secondhand exposure). Steroids and cotinine levels were measured by isotope dilution tandem mass spectrometry. Results: A significant, positive correlation was observed between hsCRP and cotinine levels indicating an association between cigarette smoking and inflammation. However, no association was found between hsCRP and cotinine levels in both the non-smoker and passive smoker group. Also, hsCRP levels were significantly associated with increased BMI scores. Conclusions: Combined factors of increased smoke exposure and obesity were significantly correlated with increased hsCRP levels, suggesting that multiple conditions confer additive risk to an inflammatory state. To determine the role of inflammation in women's health, further studies are essential to determine the interacting relationship between hsCRP and sex hormone levels in women with disease.","PeriodicalId":17132,"journal":{"name":"Journal of steroids & hormonal science","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74716227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Neuroactive steroids play a vital role in mental health, behavior, mood development, neuron-protection and memory. This review sums up what is wellknown regarding the two types of neuroactive steroids viz. allopregnanolone (ALP) and tetrahydrodeoxycorticosterone (THDOC). There is a strong correlation between body progesterone concentration and ALP production. The stage of estrus cycles determines the levels of ALP in body, however, THDOC is a stress induced neuroactive steroid and its level is changeable with the type and severity of stress. The physiological response of stress is affected by THDOC and influences paraventricular nucleus in hypothalamus which in turn controls hypothalamic-pituitary-adrenal and gonadal axis. Both neuroactive steroids are potent endogenous modulators of γ-aminobutyric acid type A (GABAA) receptors and their production gets higher during pregnancy. Now a question arises “do both classes of neuroactive steroids have a potent correlation in their action?” This manuscript will bring you up to date on the interaction and function of these two during pregnancy and postpartum depression.","PeriodicalId":17132,"journal":{"name":"Journal of steroids & hormonal science","volume":"32 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2013-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86721400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There were no patients with previously diagnosed overt hypertension. Patients with SAI received a mean of 7.39 mg/m2 of HC in 3 daily doses (in the morning (M) 50%, in the afternoon (A) 25%, in the evening (E) 25%), CAH patients 17.9 mg/m2 of HC in the following dosing schedules: 5 patients in 3 equal doses, 7 patients received M: 40% A: 40% E: 20%, the remaining 6 patients had the same dosing schedule as patients with SAI. Fludrocortisone (FC) was given to 13 patients with CAH in 2 equal daily doses. The total dose of HC/FC as well as the dosing schedule of HC was adjusted individually based on clinical and biochemical outcomes. Standard 24-hour BP monitoring (ABPM) was performed using an Ambulatory BP Monitor (Space labs 90217, USA). \u0000 \u0000Results: The majority of the patients (almost 70% SAI, 80% CAH) presented with an abnormal 24-hour BP profile. There were no significant differences in ABPM results between SAI and CAH patients, and no differences between CAH patients treated with and without FC. There was no correlation between HC and FC doses [mg/m2] and ABPM results except that mean night SBP values increased with greater HC doses (r=0.51, p<0.05). Among the CAH group the highest percentage of abnormal ABPM results was observed in patients who received HC in doses: M: 50% A: 25% and E: 25%, the most favorable BP profile was observed in patients with dosing schedule: M: 40%, A: 40%, E: 20%.However there were no significant differences between patients with different treatment protocols, the results suggest that observed disruptions of the BP profile could be related to the HC dosing schedule. \u0000 \u0000Conclusions: The incidence of abnormal BP profiles in patients on steroid replacement therapy due to SAI and CAH without overt hypertension is high. The disruptions of the BP profiles are not associated with the dose of HC or FC. The abnormal BP profiles in patients with SAI or CAH may be related to the HC dosing schedule. 24-hour ABPM seems to be a useful, non-invasive and safe method for the monitoring of HC and FC replacement therapy in patients with adrenal insufficiency. Further investigations in the larger groups of patients are needed.","PeriodicalId":17132,"journal":{"name":"Journal of steroids & hormonal science","volume":"37 1","pages":"0-0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86983823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
