Weight Variation In Users Of Depot-medroxyprogesterone Acetate, The Levonorgestrel-releasing Intrauterine System And A Copper Intrauterine Device For Up To Ten Years Of Use.

Data on record regarding weight variation in depot-medroxyprogesterone acetate (DMPA) and levonorgestrel-releasing intrauterine system (LNG-IUS) users are controversial. To date, no studies have yet evaluated weight variation in DMPA and LNG-IUS users in up to ten years of use compared to non-hormonal contraceptive users. A retrospective study analysed weight variations in 2138 women using uninterruptedly DMPA (150 mg intramuscularly, three-monthly; n = 714), the LNG-IUS (n = 701) or a copper-intrauterine device (Cu-IUD; n = 723). At the end of the first year of use, there was a mean weight increase of 1.3 kg, 0.7 kg and 0.2 kg among the DMPA-, LNG-IUS- and Cu-IUD users, respectively, compared to weight at baseline (p < 0.0001). After ten years of use, the mean weight had risen by 6.6 kg, 4.0 and 4.9 kg among the DMPA-, LNG-IUS- and Cu-IUD users, respectively. DMPA-users had gained more weight than LNG-IUS- (p = 0.0197) and than Cu-IUD users (p = 0.0294), with the latter two groups not differing significantly from each other in this respect (p = 0.5532). Users of hormonal and non-hormonal contraceptive methods gained a significant amount of weight over the years. DMPA users gained more weight over the treatment period of up to ten years than women fitted with either a LNG-IUS or a Cu-IUD.

Levonorgestrel Intrauterine Device Effectiveness in Heavy Menstrual Bleeding Treatment in Obese Women

Objective:We aimed to identify if there was any difference in Levonorgestrel-releasing intrauterine system (LNG-IUS) efficacy or weight gain when used in heavy menstrual bleeding (HMB) treatment, between obese and non-obese women. Population and methods: This was a case-controlled retrospective study undertaken between 2002-2007. 194 women with HMB were treated with LNG-IUS and stratified into two groups accordingly with body mass index (BMI): Obese Group – BMI ≥ 30 (n=53) and Non-obese Group – BMI < 30 (n=141). Age, weight, days of spotting and days of menses were analyzed at 1, 3 and 6 months after insertion and then annually until 2 years. Analytic parameters of anemia (hemoglobin, serum ferritin, mean corpuscular volume) were reviewed at pre-insertion, at 6 months and then annually until 2 years. Results: During the 2-year follow-up there was a similar improvement in two groups regarding duration of menses, spotting and in analytic parameters of anemia. A statistically significant improvement was observed in obese group after 2 years of treatment regarding analytic parameters of anemia and menstrual characteristics, without weight gain. Conclusion: In obese women, the LNG-IUS is an effective treatment for heavy menstrual bleeding, without being associated to weight gain.

Retrospective assesment of the levonorgestrel intrauterine device to treat complex atypical hyperplasia and early endometrioid endometrial cancer

Objective: The primary objective of this project was to describe the efficacy of the Levonorgestrel Intrauterine Device (LIUD) for treatment of Complex Endometrial Cancer (CAH) and Grade 1 Endometrial Cancer (G1EEC) in terms of rate of Complete Response (CR) and Partial Response (PR) after 6 months of therapy. Finally, we assessed if any clinical or pathologic features were associated with response to the LIUD. ^ Methods: This study was a retrospective case series designed to report the response rate of patients with CAH or G1EEC treated with LIUD therapy. In addition, this study has a laboratory component to assess molecular predictors of response to LIUD therapy. Retrospective data already collected from patients diagnosed with CAH or EEC grade 1 and treated with LIUD therapy at MD Anderson Cancer Center (MDACC) were used for this study. Patients from all ethnic and race groups were included. A Complete Response (CR) was defined in patients diagnosed with CAH if pathologic report at 6 months demonstrated either no evidence of hyperplasia or no atypia in the setting of simple or complex hyperplasia. Partial Response (PR) was recorded if disease downgraded to only CAH from G1EEC. No Response (NR) was recorded if pathologic report demonstrates no change (Stable Disease, SD) or progression to cancer (Progressive Disease, PD). We calculated the proportion of patients with complete response to LIUD therapy with 95% confidence interval. We compared the response rates (CR/PR vs NR) by obesity status (Obese if BMI > 40 kg/m2 vs non-obese if BMI <= 40 kg/m2) as well as other clinical and pathologic factors, such as age, uterine size (median size), and presence of exogenous progesterone effect. ^ Results: There were 39 patients diagnosed with either CAH or G1EEC treated with the LIUD. Of 39 patients, 12 did not have pathological results of biopsy at 6months time period. Of 27 evaluable patients, 17 were diagnosed with CAH and 10 with G1EEC. Overall response rate (RR) was 78% (95% CI = 62-94%) at 6 months, 18 patients had CR (4 in G1EEC; 14 in CAH), 3 patients had PR (3 in G1EEC), 3 had SD (1 in CAH; 2 in G1EEC), 3 had PD (2 in CAH; 1 in G1EEC). After histology stratification, RR at 6 months was 82.35% (14/17; 95%CI = 67.4-97.3%) in CAH and 70% (7/10; 95% CI = 41-98.4%) in G1EEC. ^ There was no difference in response (R) and no response (NR) based on BMI (p=0.56). He observed a trend showing association between age with response (p=0.1). There was no association between uterine size and response to therapy (p=0.17). We recorded strong association between exogenous progesterone effect and response. ^ Conclusion: LIUD therapy for the treatment of CAH and G1EEC may be effective and safe. Presence of exogenous progesterone effect may predict the response to LIUD therapy at earlier time points. There is need of further studies with larger sample size to explore the relationship of response with other clinical and pathologic factors^

Biofilm formation on intrauterine devices in patients with recurrent vulvovaginal candidiasis

A biofilm is a complex community of surface-associated cells enclosed in a polymer matrix. They attach to solid surfaces and their formation can be affected by growth conditions and co-infection with other pathogens. The presence of biofilm may protect the microorganisms from host defenses, as well as significantly reduce their susceptibility to antifungal agents. Pathogenic microbes can form biofilms on the inert surfaces of implanted devices such as catheters, prosthetic cardiac valves and intrauterine devices (IUDs). The present study was carried out to analyze the presence of biofilm on the surface of intrauterine devices in patients with recurrent vulvovaginal candidiasis, and to determine the susceptibility profile of the isolated yeasts to amphotericin B and fluconazole. Candida albicans was recovered from the IUDs and it was found to be susceptible to the antifungal agents when tested under planktonic growing conditions. These findings indicate the presence of the biofilm on the surface of the IUD as an important risk factor for recurrent vulvovaginal candidiasis.

UTERINE ULTRASONOGRAPHIC CHANGES DURING ENDOMETRIOSIS TREATMENT: A COMPARISON BETWEEN LEVONORGESTREL-RELEASING INTRAUTERINE DEVICES AND A GONADOTROPIN-RELEASING HORMONE AGONIST

We compared the effects of levonorgestrel-releasing intrauterine devices (LNG-IUD) and a gonadotropin-releasing hormone agonist (GnRHa) on uterine volume, uterine arteries pulsatility index (PI) and endometrial thickness before and after six months of endometriosis treatment. Sixty women aged 18-40 y were allocated randomly to one of two groups: LNG-IUDs were inserted in 30 women, and GnRHa monthly injections were performed on the other 30. All 60 women were submitted to transvaginal 2-D ultrasound scans on the day that the treatment started and then six months later. Measurements of uterine arteries PI, uterine volume and endometrial thickness were performed at both evaluations. The use of LNG-IUDs significantly decreased endometrial thickness (pre = 6.08 +/- 3.00 mm, post = 2.7 +/- 0.98 mm; mean +/- SD), as did the use of GnRHa (pre = 6.96 +/- 3.82 mm, post = 3.23 +/- 2.32 mm). The uterine volume decreased in the GnRHa group (pre = 86.67 +/- 28.38 cm(3), Post = 55.27 +/- 25.52 cm(3)), but not in the LNG-IUD group (pre = 75.77 +/- 20.88 cm(3), post = 75.97 +/- 26.62 cm(3)). Uterine arteries PI increased for both groups; however, the increase was higher in the GnRHa group (0.99 +/- 0.84 vs. 0.38 +/- 0.84, p = 0.007; PI increase in GnRHa and in LNG-IUD groups, respectively). In conclusion, levonorgestrel released directly onto the endometrium by the LNG-IUD induced smaller uterine changes than did the hypoestrogenism induced by GnRHa. Nevertheless, both promoted similar effects on endometrial thickness. (E-mail: wpmartins@gmail.com) (C) 2008 World Federation for Ultrasound in Medicine & Biology.

Reasons For Brazilian Women To Switch From Different Contraceptives To Long-acting Reversible Contraceptives.

Long-acting reversible contraceptives (LARCs) include the copper-releasing intrauterine device (IUD), the levonorgestrel-releasing intrauterine system (LNG-IUS) and implants. Despite the high contraceptive efficacy of LARCs, their prevalence of use remains low in many countries. The objective of this study was to assess the main reasons for switching from contraceptive methods requiring daily or monthly compliance to LARC methods within a Brazilian cohort. Women of 18-50 years of age using different contraceptives and wishing to switch to a LARC method answered a questionnaire regarding their motivations for switching from their current contraceptive. Continuation rates were evaluated 1 year after method initiation. Sample size was calculated at 1040 women. Clinical performance was evaluated by life table analysis. The cutoff date for analysis was May 23, 2013. Overall, 1167 women were interviewed; however, after 1 year of use, the medical records of only 1154 women were available for review. The main personal reason for switching, as reported by the women, was fear of becoming pregnant while the main medical reasons were nausea and vomiting and unscheduled bleeding. No pregnancies occurred during LARC use, and the main reasons for discontinuation were expulsion (in the case of the IUD and LNG-IUS) and a decision to undergo surgical sterilization (in the case of the etonogestrel-releasing implant). Continuation rate was ~95.0/100 women/year for the three methods. Most women chose a LARC method for its safety and for practical reasons, and after 1 year of use, most women continued with the method.

Estimated Disability-adjusted Life Years Averted By Long-term Provision Of Long Acting Contraceptive Methods In A Brazilian Clinic.

What is the contribution of the provision, at no cost for users, of long acting reversible contraceptive methods (LARC; copper intrauterine device [IUD], the levonorgestrel-releasing intrauterine system [LNG-IUS], contraceptive implants and depot-medroxyprogesterone [DMPA] injection) towards the disability-adjusted life years (DALY) averted through a Brazilian university-based clinic established over 30 years ago. Over the last 10 years of evaluation, provision of LARC methods and DMPA by the clinic are estimated to have contributed to DALY averted by between 37 and 60 maternal deaths, 315-424 child mortalities, 634-853 combined maternal morbidity and mortality and child mortality, and 1056-1412 unsafe abortions averted. LARC methods are associated with a high contraceptive effectiveness when compared with contraceptive methods which need frequent attention; perhaps because LARC methods are independent of individual or couple compliance. However, in general previous studies have evaluated contraceptive methods during clinical studies over a short period of time, or not more than 10 years. Furthermore, information regarding the estimation of the DALY averted is scarce. We reviewed 50 004 medical charts from women who consulted for the first time looking for a contraceptive method over the period from 2 January 1980 through 31 December 2012. Women who consulted at the Department of Obstetrics and Gynaecology, University of Campinas, Brazil were new users and users switching contraceptive, including the copper IUD (n = 13 826), the LNG-IUS (n = 1525), implants (n = 277) and DMPA (n = 9387). Estimation of the DALY averted included maternal morbidity and mortality, child mortality and unsafe abortions averted. We obtained 29 416 contraceptive segments of use including 25 009 contraceptive segments of use from 20 821 new users or switchers to any LARC method or DMPA with at least 1 year of follow-up. The mean (± SD) age of the women at first consultation ranged from 25.3 ± 5.7 (range 12-47) years in the 1980s, to 31.9 ± 7.4 (range 16-50) years in 2010-2011. The most common contraceptive chosen at the first consultation was copper IUD (48.3, 74.5 and 64.7% in the 1980s, 1990s and 2000s, respectively). For an evaluation over 20 years, the cumulative pregnancy rates (SEM) were 0.4 (0.2), 2.8 (2.1), 4.0 (0.4) and 1.3 (0.4) for the LNG-IUS, the implants, copper IUD and DMPA, respectively and cumulative continuation rates (SEM) were 15.1 (3.7), 3.9 (1.4), 14.1 (0.6) and 7.3 (1.7) for the LNG-IUS, implants, copper IUD and DMPA, respectively (P < 0.001). Over the last 10 years of evaluation, the estimation of the contribution of the clinic through the provision of LARC methods and DMPA to DALY averted was 37-60 maternal deaths; between 315 and 424 child mortalities; combined maternal morbidity and mortality and child mortality of between 634 and 853, and 1056-1412 unsafe abortions averted. The main limitations are the number of women who never returned to the clinic (overall 14% among the four methods under evaluation); consequently the pregnancy rate could be different. Other limitations include the analysis of two kinds of copper IUD and two kinds of contraceptive implants as the same IUD or implant, and the low number of users of implants. In addition, the DALY calculation relies on a number of estimates, which may vary in different parts of the world. LARC methods and DMPA are highly effective and women who were well-counselled used these methods for a long time. The benefit of averting maternal morbidity and mortality, child mortality, and unsafe abortions is an example to health policy makers to implement more family planning programmes and to offer contraceptive methods, mainly LARC and DMPA, at no cost or at affordable cost for the underprivileged population. This study received partial financial support from the Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP), grant # 2012/12810-4 and from the National Research Council (CNPq), grant #573747/2008-3. B.F.B., M.P.G., and V.M.C. were fellows from the scientific initiation programme from FAPESP. Since the year 2001, all the TCu380A IUD were donated by Injeflex, São Paulo, Brazil, and from the year 2006 all the LNG-IUS were donated by the International Contraceptive Access Foundation (ICA), Turku, Finland. Both donations are as unrestricted grants. The authors declare that there are no conflicts of interest associated with this study.

Safety of the etonogestrel-releasing implant during the immediate postpartum period: a pilot study

Background: The effects of etonogestrel (ETG)-releasing contraceptive implant during the immediate postpartum period on maternal safety are unknown. Study design: Forty healthy women exclusively breastfeeding were randomized to receive either ETG-releasing implant 24-48 h after delivery (n=20) or depot medroxyprogesterone acetate (DMPA group; n=20) at the sixth week postpartum. We measured blood pressure, maternal and neonatal weight, body mass index (BMI; kg/m(2)), waist circumference (WC), complete blood count, C-reactive protein, interleukin-6, tumor necrosis factor (TNF-alpha), lipid profile, fasting serum glucose and maintenance of exclusive lactation up to the 12th week postpartum. Results: Decreases in mean maternal weight, BMI (kg/m(2)) and WC were significantly greater in the ETG-releasing implant group than in the MPA group during the first 6 weeks postpartum (-4.64 +/- 2.71 kg vs. -2.6 +/- 2.45 kg mean +/- SD, p=.017; -1.77 +/- 1.06 kg/m(2) vs. -0.97 +/- 0.95 kg/m(2), p=.026; -15.3 +/- 6.72 cm vs. -9.05 +/- 5.84 cm, p=.003, respectively). In addition, total cholesterol and HDL, were lower in DMPA users, and TNF-alpha and leukocytes were higher in DMPA users compared to in the implant group, between 6 and 12 weeks after delivery. The newborns of implant users showed a trend towards gaining more weight, as compared with the infants of the DMPA mothers during the first 6 weeks of life (implant group: +1460.50 +/- 621.34 g vs. DMPA group: +1035.0 +/- 562.43 g, p=.05). The remaining variables, including the duration of exclusive breastfeeding, were similar between the groups. Conclusion: The insertion of ETG-releasing contraceptive implant during the immediate postpartum period was not associated with deleterious maternal clinical effects or with significant maternal metabolic alterations or decreased infant weight gain.

Factores de riesgo asociados a embarazo ectópico

Introducción: El embarazo ectópico es la primera causa de mortalidad materna durante el primer trimestre del embarazo, y la realidad sociocultural de nuestro país indica que las mujeres están exponiéndose cada vez más a factores que aumentan el riesgo para embarazo ectópico. Se pretende evaluar la asociación de los factores de riesgo en una institución de cuarto nivel. Metodología: Se realizó un estudio de casos y controles, con un caso por cada dos controles, escogidos por medio de un muestreo aleatorio simple. Resultados: Se incluyó un total de 200 pacientes. Ambas poblaciones fueron comparables. La edad promedio de casos fue 29 años y de los controles 24.6 años; la mayoría estaban casadas o en unión libre. Con respecto a los factores de riesgo con resultados estadísticamente significativos (p 0,000) se encontró que existe un mayor riesgo de embarazo ectópico con edad entre 18-35 años, estrato socioeconómico bajo, presencia de ETS, estar casada, tener periodo intergenésico prolongado, haber tenido cirugías pélvicas previas, no usar anticonceptivos, tener endometriosis y tener antecedente de embarazo ectópico (p=0,000). El factor de riesgo más alto es el antecedente de un embarazo ectópico previo OR 66.2 IC95% 60.4 – 72.0 seguido de tener endometriosis con OR 20.2 IC95% 18.6 – 21.9. (p 0,000). Discusión: Los factores de riesgo para embarazo ectópico en el presente estudio son concordantes con otros descritos en la literatura. Es importante conocer a fondo los datos presentados para mejorar los índices de esta patología a nivel nacional.

Women's knowledge of health effects of oral contraceptives in five Brazilian cities

Background: Although acceptability of combined oral contraceptives (COCs) is widespread, patients are often unaware of the noncontraceptive benefits. Study Design: An opinion survey through telephone interview was conducted to evaluate the knowledge of 500 Brazilian women 15-45 years of age who were current users or had recently used COCs. Data were obtained on their knowledge of adverse events, the effects of COCs on health- and menstrual-related symptoms, noncontraceptive benefits and aspects related to sexual response. Results: Most of the women interviewed learned about the pill from doctors or the Internet. Other than the pill, the best-known contraceptive methods were the condom and intrauterine device. The majority of women believe that COCs do not change the risk of gynecological cancers. Most believed that they had no significant effect on sexual response. Conclusions: COCs users in Brazil lack precise information on aspects related to general health, particularly menstrual-related symptoms and noncontraceptive health benefits. (C) 2012 Elsevier Inc.

Deployed military women: A second look at gender-specific infections

This descriptive, cross-sectional study addressed the relationship between variables of deployed military women and prevalence of gender-specific infections. The analysis of secondary data will look at the last deployment experience of 880 randomly selected U.S. military women who completed a mailed questionnaire (Deployed Female Health Practice Questionnaire (FHPQ)) in June 1998. The questionnaire contained 191 items with 80 data elements and one page for the subject's written comments. The broad categories of the questionnaire included: health practices, health promotion, disease prevention and treatment, reproduction, lifestyle management, military characteristics and demographics. The research questions are: (1) What is the prevalence of sexually transmitted diseases (STD), urinary tract infections (UTI) and vaginal infections (VI) related to demographic data, military characteristics, behavioral risk factors and health practices of military women during their last deployment? and (2) What are the differences between STD, UTI and VI related to the demographic data, military characteristics, behavioral risk factors and health practices of military women during their last deployment. The results showed that (1) STDs were found to be significantly associated with age and rank but not location of deployment or military branch; (2) UTI were found to be significantly associated with intrauterine device (IUD) use, prior UTI and type of items used for menses management, but not education or age; and (3) VI were significantly associated with age, rank and deployment location but not ethnicity or education. Although quantitative research exploring hygiene needs of deployed women continues, qualitative studies may uncover further “hidden” issues of importance. It cannot be said that the military has not made proactive changes for women, however, continued efforts to hone these changes are still encouraged. Mandatory debriefings of “seasoned” deployed women soldiers and their experiences would benefit leadership and newly deployed female soldiers with valuable “lessons learned.” Tailored hygiene education material, prevention education classes, easy access website with self-care algorithms, pre-deployment physicals, revision of military protocols for health care providers related to screening, diagnosing and treatment of gender-specific infections and process changes in military supply network of hygiene items for women are offered as recommendations. ^

A CASE-CONTROL STUDY OF RISK FACTORS FOR ECTOPIC PREGNANCY (ROCHESTER, MINNESOTA, OBSTETRICS)

A population-based case-control study of risk factors for ectopic pregnancy has been conducted. The investigation includes 274 cases diagnosed in Rochester, Minnesota residents from 1935 through 1982, and 548 matched controls selected from live birth deliveries. Risk factor information documented prior to the last index menstrual period was obtained via medical record abstract for 22 potential risk factor variables.^ Univariate matched analyses revealed nine variables with significantly elevated odds ratios (ORs). Following conditional logistic regression for matched sets, four variables remained as significant risk factors for ectopic pregnancy. These risk factors with ORs and 95% confidence intervals (Cls) were: current intrauterine device use (OR = 13.7, Cl = 1.6 - 120.6), infertility (OR = 2.6, Cl = 1.6 - 4.2), pelvic inflammatory disease (OR = 3.3, Cl = 1.6 - 6.6), and tubal surgery (OR = 4.5, Cl = 1.5 - 13.9). After adjusting for these four major risk factors, the following variables did not have statistically significant ORs: abdominal/pelvic surgery (OR = 2.0), acute appendicitis (OR = 2.0), anovulation (OR = 1.2), clomiphene citrate use during the index conception (OR = 3.5), induced abortion (OR = 2.1), in utero exposure to diethylstilbestrol (OR = 1.6), myomas (OR = 0.7), ovarian cysts (OR = 1.0), and past intrauterine device use (OR = 1.2). ^

Increasing male involvement in family planning decision making: trial of a social-cognitive intervention in rural Vietnam

We tested a social-cognitive intervention to influence contraceptive practices among men living in rural communes in Vietnam. It was predicted that participants who received a stage-targeted program based on the Transtheoretical Model (TTM) would report positive movement in their stage of motivational readiness for their wife to use an intrauterine device (IUD) compared to those in a control condition. A quasi-experimental design was used, where the primary unit for allocation was villages. Villages were allocated randomly to a control condition or to two rounds of intervention with stage-targeted letters and interpersonal counseling. There were 651 eligible married men in the 12 villages chosen. A significant positive movement in men's stage of readiness for IUD use by their wife occurred in the intervention group, with a decrease in the proportions in the precontemplation stage from 28.6 to 20.2% and an increase in action/maintenance from 59.8 to 74.4% (P < 0.05). There were no significant changes in the control group. Compared to the control group, the intervention group showed higher pros, lower cons and higher self-efficacy for IUD use by their wife as a contraceptive method (P < 0.05). Interventions based on social-cognitive theory can increase men's involvement in IUD use in rural Vietnam and should assist in reducing future rates of unwanted pregnancy.

Predictors of men's acceptance of modern contraceptive practice: Study in rural Vietnam

Studies have shown family planning adoption is likely to be more effective for women when men are actively involved. The transtheoretical model of behavior change was used to examine men's involvement in general contraception and intrauterine device (IUD) use by their wives. The study was carried out in rural Vietnam with 651 eligible participants. Cons of IUD use for men in precontemplation and contemplation/preparation were significantly higher than those in the action/maintenance stages, whereas the reverse was true for pros of IUD. The self-efficacy for convincing wife to have IUD in precontemplation was significantly lower than for those in higher stages. Women's education and ages, spontaneous recall of modem contraceptive method, cons for IUD, and self-efficacy for contraception and for convincing wives to get IUD inserted (or continue use) were significant predictors of men's readiness to accept IUD. Interventions are targeted to reduce cons and increase self-efficacy for IUD use.
