Analysis of Obstetric Outcomes by Hospital Location, Volume, and Teaching Status Associated With Non-Medically Indicated Induction of Labor at 39 Weeks.

Importance: Non-medically indicated induction of labor has been demonstrated to potentially improve some obstetric outcomes, such as decreasing cesarean birth. It has been reported that rates of cesarean birth and other obstetric outcomes vary among hospitals with different characteristics. Objective: To assess whether obstetric outcomes differ between nulliparous individuals with low-risk pregnancies managed with non-medically indicated induction of labor compared with expectant management in different types of hospitals. Design, Setting, and Participants: This retrospective cohort study included non-medically indicated induction of labor at 39 weeks' gestation compared with expectant management of singleton, nonanomalous, births in nulliparous women with low-risk pregnancies in California between January 1, 2007, and December 31, 2011. The initial analysis of these data was performed in 2021. Outcomes were assessed by 3 hospital characteristics: location (urban vs rural), obstetric volume, and teaching (academic vs community) status. Volume was categorized based on the average number of births per year and grouped into low (<1200 births per year), medium (1200-2399 births per year), and high (≥2400 births per year). Births with previous or planned cesarean delivery were excluded, and non-medically indicated induction of labor was defined as induction of labor without a specific medical indication. Testing with χ2 and multivariable logistic regression analyses was used for statistical comparisons with a cutoff level of P = .01. Exposure: Non-medically indicated induction of labor at 39 weeks' gestation. Main Outcomes and Measures: The primary outcome was cesarean birth, and numerous secondary perinatal outcomes were also assessed. Results: There were 455 044 births included in this study. When stratified by hospital variables, a number of sociodemographic characteristics were significantly different, such as race and ethnicity, age, body mass index, and insurance type. The adjusted odds ratios (aORs) of cesarean birth were significantly lower in all settings with induction of labor except for low-volume hospitals, in which there was no significant difference (aOR, 0.95; 95% CI, 0.82-1.09). Chorioamnionitis and postpartum hemorrhage were lower with induction of labor among nearly every hospital when stratified by hospital characteristics. Neonatal outcomes were improved in all settings with induction of labor compared with expectant management. Conclusions and Relevance: These findings suggest that non-medically indicated induction of labor may be associated with a lower rate of cesarean births and some maternal and neonatal adverse outcomes in a range of hospital settings.

FokI polymorphism of Vitamin D receptor gene and deficiency of serum Vitamin D increases the risk of breast cancer in North Indian women.

INTRODUCTION: Breast cancer is a leading cause of cancer morbidity and mortality in females. Decreased availability of Vitamin D within breast cells, contributed by deficiency of serum Vitamin D and polymorphisms of Vitamin D receptor genes are possible risk factors for breast cancer. OBJECTIVES: To study the association of FokI polymorphism of the Vitamin D Receptor gene with breast cancer in females and to study the levels of Vitamin D in breast cancer patients. MATERIALS AND METHODS: VDR gene FokI genotyping was done by PCR-RFLP method and levels of serum Vitamin D were estimated by ELISA. Statistical analysis was done with SPSS v.21. RESULTS: Serum Vitamin D was significantly lower in newly diagnosed breast cancer patients than in healthy controls (P = 0.016). Females with serum Vitamin D levels in the highest quartile have a lesser risk of breast cancer than those with serum Vitamin D levels in the lowest quartile (O. R = 2.4421, C.I = 1.09-5.45, P = 0.029). The risk of developing breast cancer is higher in women with the polymorphic T allele for VDR FokI genotype (CT/TT) than those homozygous for the wild C allele (CC). (O.R. = 4.295, C.I. = 2.2110-8.3451, p-value = <0.0001). Levels of serum Vitamin D were significantly higher (p < 0.001) in ER + patients and significantly low in those presenting with higher stages of cancer (p = 0.009). CONCLUSIONS: FokI polymorphism of VDR gene and low circulating Vitamin D levels increase the risk of developing breast cancer in North Indian females. Serum Vitamin D can be used as a prognostic factor.

Global Mortality From Firearms, 1990-2016.

Importance: Understanding global variation in firearm mortality rates could guide prevention policies and interventions. Objective: To estimate mortality due to firearm injury deaths from 1990 to 2016 in 195 countries and territories. Design, Setting, and Participants: This study used deidentified aggregated data including 13 812 location-years of vital registration data to generate estimates of levels and rates of death by age-sex-year-location. The proportion of suicides in which a firearm was the lethal means was combined with an estimate of per capita gun ownership in a revised proxy measure used to evaluate the relationship between availability or access to firearms and firearm injury deaths. Exposures: Firearm ownership and access. Main Outcomes and Measures: Cause-specific deaths by age, sex, location, and year. Results: Worldwide, it was estimated that 251 000 (95% uncertainty interval [UI], 195 000-276 000) people died from firearm injuries in 2016, with 6 countries (Brazil, United States, Mexico, Colombia, Venezuela, and Guatemala) accounting for 50.5% (95% UI, 42.2%-54.8%) of those deaths. In 1990, there were an estimated 209 000 (95% UI, 172 000 to 235 000) deaths from firearm injuries. Globally, the majority of firearm injury deaths in 2016 were homicides (64.0% [95% UI, 54.2%-68.0%]; absolute value, 161 000 deaths [95% UI, 107 000-182 000]); additionally, 27% were firearm suicide deaths (67 500 [95% UI, 55 400-84 100]) and 9% were unintentional firearm deaths (23 000 [95% UI, 18 200-24 800]). From 1990 to 2016, there was no significant decrease in the estimated global age-standardized firearm homicide rate (-0.2% [95% UI, -0.8% to 0.2%]). Firearm suicide rates decreased globally at an annualized rate of 1.6% (95% UI, 1.1-2.0), but in 124 of 195 countries and territories included in this study, these levels were either constant or significant increases were estimated. There was an annualized decrease of 0.9% (95% UI, 0.5%-1.3%) in the global rate of age-standardized firearm deaths from 1990 to 2016. Aggregate firearm injury deaths in 2016 were highest among persons aged 20 to 24 years (for men, an estimated 34 700 deaths [95% UI, 24 900-39 700] and for women, an estimated 3580 deaths [95% UI, 2810-4210]). Estimates of the number of firearms by country were associated with higher rates of firearm suicide (P < .001; R2 = 0.21) and homicide (P < .001; R2 = 0.35). Conclusions and Relevance: This study estimated between 195 000 and 276 000 firearm injury deaths globally in 2016, the majority of which were firearm homicides. Despite an overall decrease in rates of firearm injury death since 1990, there was variation among countries and across demographic subgroups.

Serum lipid profile in female patients with severe acne vulgaris.

BACKGROUND: Acne vulgaris is one of the most common skin conditions affecting young adults. The relationship between lipid profile or lipid ratios and acne is not widely reported. METHODS: A case control study was performed in 90 females with severe acne vulgaris. Lipid profiles were measured, lipid ratios were calculated, and results were compared with 90 age matched healthy controls. RESULTS: Total cholesterol, LDL-C, HDL-C, Apo A1, though, were significantly higher in patients as compared to healthy controls but all the levels in patients were within normal range so we calculated lipid ratios for TC/HDL, LDL/HDL, TG/HDL, Apo B/Apo A1, Atherogenic index of plasma and found that all the ratios were significantly higher as compared to controls using a t-test. The area under receiver operating characteristic curve was > 0.7 for all the lipid ratios and sensitivity and specificity were calculated for all the ratios and it was highest for Apo A1/Apo B. CONCLUSIONS: We suggest using lipid ratios as a screening test in females with acne vulgaris to diagnose dyslipidemia at an early stage but further studies are required to see the effect of treating hyperlipidemia in females with severe acne vulgaris.

Endogenous hormones in postmenopausal females with breast cancer--before and after treatment.

BACKGROUND: Breast cancer is usually present for many years (as long as 5-10 years) before it can be clinically diagnosed (theory of the 'dormant malignant cell'). This implies that breast cancer cells, during their subclinical period, are likely to have been exposed for a considerable time to endogenous sex hormones and endogenous hormonal milieu predicts the chances of breast cancer in females. So, we planned this study to evaluate the role of endogenous hormones in postmenopausal females excluding the patients on hormone replacement therapy as the relationship between breast cancer and hormone replacement therapy is well known. METHODS: Hormone therapy is known to affect these hormone levels but whether treatment of breast cancer per se also decreases the hormone levels is not known. We planned the present study to determine hormone levels in patients before and after 4 months of treatment (chemotherapy/surgery and radiotherapy). Circulating hormone levels were measured using a chemiluminescence method. Their results were compared with a group of 25 age matched healthy controls. RESULTS: We found that serum prolactin, testosterone and estrogen levels were very significantly higher in patients before treatment (Group I) as compared to controls (Group III). Serum prolactin and serum estrogen levels were significantly higher and serum testosterone was very significantly higher in patients before treatment (Group I) when compared after 4 months of treatment (Group II). Only serum estrogen levels were significantly high in patients after treatment (Group II) as compared to controls (Group III). Serum progesterone levels showed no significant difference to any of the groups. CONCLUSIONS: We concluded that postmenopausal females with breast cancer have abnormalities in hormone levels. These abnormalities may be considered in the pathogenesis of the disease and should be taken into account in the treatment of patients of breast cancer. It might also be helpful to delay the onset of cancer by normalizing the levels of these hormones and in deciding the treatment modality for the patients once breast cancer has been diagnosed but further studies are required to prove the benefit of measuring serum hormone levels as a screening test.

Correlation of creatinine with TSH levels in overt hypothyroidism - a requirement for monitoring of renal function in hypothyroid patients?

OBJECTIVE: Renal function is influenced by thyroid status. Therefore, this study was done to determine the relationship between renal function and different degrees of thyroid dysfunction. DESIGN AND METHODS: Thyroid and kidney function tests were analyzed in 47 patients with overt (TSH ≥ 10.0 µIU/L) and 77 patients with subclinical hypothyroidism (TSH 6.0-9.9 µIU/L) in a cross-sectional study. These were compared with 120 age- and sex-matched euthyroid controls. RESULTS: Overt hypothyroid subjects showed significantly raised serum urea, creatinine and uric acid levels as compared to controls whereas subclinical hypothyroid patients showed significant increased levels of serum urea and creatinine levels. TSH showed significant positive correlation with creatinine and uric acid values and, fT4 had a negative correlation with uric acid in overt hypothyroidism. CONCLUSION: Hypothyroid state is associated with significant derangement in biochemical parameters of renal function. Hence the renal function should be regularly monitored in hypothyroid patients.

Role of hormones in acne vulgaris.

OBJECTIVE: To elucidate the role of endogenous hormones like testosterone, progesterone, estrogen, insulin-like growth factor, insulin and glucocorticoids in a common skin condition acne vulgaris. DESIGN AND METHODS: We conducted a systematic review of the literature and abstracted the data for every published cut point. RESULTS: We screened more than 1000 studies and found that serum testosterone, progesterone, glucocorticoids, insulin and insulin-like growth factors are increased in patients with acne vulgaris and serum estrogen levels are low in patients. CONCLUSIONS: Various endogenous hormones play important role in the pathogenesis of acne vulgaris. Thus, in the clinical practice it is important to evaluate serum levels of these hormones and patients must be treated accordingly to avoid serious endocrine disorders at an early age.

The relationship of lipid profile and menstrual cycle with acne vulgaris.

OBJECTIVE: The aim of this study was to find lipid profile and hormone levels in patients with severe acne vulgaris and to correlate lipid profile with hormone levels. DESIGN AND METHODS: Prospective study was performed in the 60 patients of severe acne vulgaris. Lipid profile and serum testosterone, estrogen, and progesterone levels were measured in three consecutive menstrual cycles during luteal phase (19th to 21st day). Their results were compared with a group of 60 age-matched healthy controls. RESULTS: Total cholesterol (TC), LDL-C, testosterone, and progesterone levels were higher in patients. Estrogen and HDL-C levels were decreased in patients. Positive correlation was found between testosterone and TC and LDL-C. Estrogen levels were positively correlated with VLDL-C, triglyceride levels, and HDL-C and negatively correlated with TC and LDL-C. CONCLUSIONS: These abnormalities must be considered in the pathogenesis of the disease and must be taken into account for the treatment of patients of acne.
