Depo-medroxyprogesterone acetate, weight gain and amenorrhea among obese adolescent and adult women

Clomiphene citrate as a new modality in management of vaginal bleeding with depomedroxyprogesterone acetate (DMPA): A randomized controlled trial

BACKGROUND

Depo-medroxyprogesterone acetate (DMPA) functions as a contraceptive method by inhibiting the secretion of gonadotropins, which prevents follicular maturation and ovulation, as well as thinning of the endometrium leading to unscheduled vaginal bleeding and subsequent discontinuation of DMPA. Our study aimed to evaluate the efficacy and safety of clomiphene citrate (CC) in stopping bleeding among DMPA users.

MATERIALS AND METHODS

We randomly assigned 200 DMPA users using a computer-generated random numbers table in a 1:1 ratio to one of two groups; the study group, which received CC at a dose of 50 mg twice daily for five days (n = 100), and the control group, which received a placebo for five days (n = 100). Our primary outcome measure was the onset and duration of bleeding cessation. Secondary outcomes included endometrial thickness, recurrence of vaginal bleeding, and any reported side effects associated with CC use.

RESULTS

Clomiphene citrate significantly resulted in early cessation of vaginal bleeding in 83 % of the patients, which continued for three months of follow-up. In addition, the recurrence of vaginal bleeding was significantly reduced in the CC group compared to the control group (11 % vs. 67 %; p < 0.001). Endometrial thickness was significantly greater in the CC group than in the control group (p < 0.001). Breast tenderness was more frequently reported in the study group, with no difference in dyspareunia between the two groups.

CONCLUSIONS

Clomiphene citrate is effective in controlling bleeding among DMPA users. Further studies are encouraged to confirm our findings.

Contraceptive switch and abandonment among women using the pill, condoms and injectables in Brazil

OBJECTIVE

The aim of our study was to assess the covariates of contraceptive switching and abandonment among Brazilian women stratified by oral pills, condoms and injectables.

MATERIALS AND METHODS

Women attending primary health care services in three Brazilian mid- to large-sized cities were interviewed face-to-face about their contraceptive practices (n = 2,051). Data were collected using a contraceptive calendar. Analysis included estimates using Kaplan-Meier multiple-decrement life-table probabilities and discrete-time hazards modelling of switching from a method to another or to no method.

RESULTS

Among 3,280 segments of contraceptive use, we observed that five-year contraceptive switching rates ranged from 34.9% among injectable users to 56.1% among pill users. Of particular concern were the high discontinuation rates of abandonment, which ranged from 50.9% among injectable users to 77.4% among pill users. Covariates of method switching and abandonment varied by type of method, but age, race/ethnicity, religion and relationship status must be highlighted as key elements of discontinuation.

CONCLUSION

Contraceptive method switching and abandoning are frequent outcomes of contraceptive use. Understanding the factors that shape women's decisions to continue or discontinue the use of a contraceptive method can help tailoring comprehensive contraceptive counselling that meet their expectations and reproductive needs when starting using a method.

Reproductive health after thoracic transplantation: An ISHLT expert consensus statement

Pregnancy after thoracic organ transplantation is feasible for select individuals but requires multidisciplinary subspecialty care. Key components for a successful pregnancy after lung or heart transplantation include preconception and contraceptive planning, thorough risk stratification, optimization of maternal comorbidities and fetal health through careful monitoring, and open communication with shared decision-making. The goal of this consensus statement is to summarize the current evidence and provide guidance surrounding preconception counseling, patient risk assessment, medical management, maternal and fetal outcomes, obstetric management, and pharmacologic considerations.

Hypertension and contraceptive use among women of child-bearing age in the United States from 2001 to 2018

BACKGROUND

Hypertension (HTN) in pregnancy is a leading cause of maternal mortality in the United States. Contraception is widely used, and estrogen-based combined hormonal forms are known to increase blood pressure (BP). With nearly half of pregnancies unplanned and many antihypertensive medications teratogenic, appropriate contraception is critical in child-bearing age women with HTN.

METHODS

Using the National Health and Nutrition Examination Surveys (NHANES) from 2001 to 2018, we evaluated contraception and antihypertensive medication use in women of child-bearing age (20-50 years). Women who had undergone sterilization or menopause were excluded. HTN was defined based on a self-reported provider diagnosis and BP ≥130/80 mm Hg or antihypertensive medication use. Contraception included non-barrier methods (pills/patch/ring, injections, long-acting reversible contraceptives) or consistent condom use. Multivariable logistic regression was used to model the odds of contraception use. Temporal trends in contraception use were reported.

RESULTS

Of the 8726 women, 12.4% had HTN with mean age (standard error) 36.0 (0.3) years. In women with HTN, 9.2% used non-barrier contraception and 10.4% used condoms only. Over half (52.7%) of women with HTN on antihypertensive medications were taking medications contraindicated in pregnancy, with no difference seen by contraceptive status. In logistic regression models, contraceptive use was lower in the older-aged women. In women with HTN on non-barrier contraception, combined hormonal contraceptive use declined, from 100% (2001-2006) to 81.4% (2013-2018, P < 0.001).

CONCLUSIONS

Many women with self-reported HTN are not using adequate contraception. Of the small proportion on non-barrier contraceptives, the majority are using estrogen-based, BP-raising methods.

Obesity, Body Composition, and Sex Hormones: Implications for Cardiovascular Risk

Cardiovascular disease (CVD) continues to be the leading cause of death in adults, highlighting the need to develop novel strategies to mitigate cardiovascular risk. The advancing obesity epidemic is now threatening the gains in CVD risk reduction brought about by contemporary pharmaceutical and surgical interventions. There are sex differences in the development and outcomes of CVD; premenopausal women have significantly lower CVD risk than men of the same age, but women lose this advantage as they transition to menopause, an observation suggesting potential role of sex hormones in determining CVD risk. Clear differences in obesity and regional fat distribution among men and women also exist. While men have relatively high fat in the abdominal area, women tend to distribute a larger proportion of their fat in the lower body. Considering that regional body fat distribution is an important CVD risk factor, differences in how men and women store their body fat may partly contribute to sex-based alterations in CVD risk as well. This article presents findings related to the role of obesity and sex hormones in determining CVD risk. Evidence for the role of sex hormones in determining body composition in men and women is also presented. Lastly, the clinical potential for using sex hormones to alter body composition and reduce CVD risk is outlined. © 2022 American Physiological Society. Compr Physiol 12:1-45, 2022.

Clinical approaches to minimize iatrogenic weight gain in children and adolescents

Clinical providers may underestimate the role of management of diseases that can occur with obesity, termed co-morbid conditions, distinct from disease that arise as a result of obesity, co-morbidities. Many of these conditions are associated with iatrogenic weight gain, and can interfere with weight loss outcomes in children and adolescents with obesity. Management of co-morbid conditions, and thoughtful selection of medications associated with weight neutrality or weight loss may increase the effectiveness of obesity treatment strategies. The aim of this commentary is to summarize the literature and discuss considerations for obesity treatment in the context of the more complicated patient, which often requires strategic management of co-morbid conditions and minimizing iatrogenic weight gain.
