RESUMEN

Introduction: A substantial percentage of patients undergoing bariatric surgery are of childbearing age. Pregnancy outcomes after bariatric surgery are known. However, there are limited data on the impact of pregnancy on weight loss after surgery. Objectives: This study aims to evaluate the effects of pregnancy on post-bariatric surgery weight loss trajectories (WLTs) and to determine the association with age and initial weight. Methods: All who had primary bariatric surgeries (Roux-en-Y gastric bypass or sleeve) between September 2015 and July 2020 were classified into two groups: post-surgery gravid (GG) and post-surgery non-gravid (NG). WLTs were examined using a random intercept mixed-effects model with repeated measures nested within patients. The post-surgery/pre-gravid time phase (PoPG) was modelled using a third-degree polynomial. For GG, two third-degree spline functions modelled the post-surgery while gravid (PoWG) and post-partum (PoPP) time phases. Age and initial weight were used to control for pre-existing differences during PoPG. Weight differences at 6 months PoPP were examined by applying general linear hypothesis testing to the mixed-model results. Results: A total of 508 patients were included, 20 in GG and 488 in NG. The mean age at surgery was 33 years in GG and 37 years in NG. The mean initial BMI was 47 kg/m2 and 43 kg/m2, respectively. During PoPG, adjusted average weight in both groups follows the path across time. For GG, weight decreases and then increases during PoWG. For GG during PoPP, weight immediately decreases after delivery and then increases over time to levels similar to NG. Weight differences at 6 months PoPP for GG and NG were not statistically different. Older age was associated with reduced weight loss during PoPG by Baseline Age, while higher initial weight was associated with increased weight loss during PoPG by Baseline Weight. In both instances, these effects attenuate over time. Conclusions: This model indicates that pregnancy following bariatric surgery affects WLT during PoWG and PoPP, and no difference in weight is expected after 6 months post-gravid. Age and initial weight could be considered prognostic factors during PoPG. Patients wishing to conceive should undergo preconception counselling and be advised to avoid pregnancy during the period of rapid weight loss. They also should be informed that WLT may vary during pregnancy and early post-partum.

RESUMEN

INTRODUCTION: The aim of this study was to evaluate cardiovascular disease (CVD) risk modification in patients with optimal weight loss (OWL) versus suboptimal weight loss SWL following MBS. METHODS: This was a retrospective analysis. The 10-year risk CVD was estimated before and after one year of surgery using the "Framingham Score". RESULTS: 191 patients were included in our study. Mean baseline Framingham score was 7.2 â€‹± â€‹6.9%. According to the score, 54% of patients were classified as low risk (n â€‹= â€‹104), 23% as moderate (n â€‹= â€‹43), 20% moderately high (n â€‹= â€‹39) and 3% as high risk (n â€‹= â€‹5). One year after surgery, 91% of the patients showed reduction of their Framingham score. Mean CVD risk score decreased significantly to 4.1 â€‹± â€‹3.7% when compared to baseline (p-value is â€‹< â€‹0.001); 80% of patients classified as low risk (n â€‹= â€‹153), 13% as moderate (n â€‹= â€‹25), 7% moderately high (n â€‹= â€‹13) and 0% as high risk (n â€‹= â€‹0). CONCLUSION: Weight loss after bariatric surgery reduces CVD risk scores and the magnitude of effect correlates with the degree of weight loss.

RESUMEN

BACKGROUND: Machine learning (ML) is an emerging technology with the potential to predict and improve clinical outcomes including adverse events, based on complex pattern recognition. Major adverse cardiac events (MACE) after bariatric surgery have an incidence of 0.1% but carry significant morbidity and mortality. Prior studies have investigated these events using traditional statistical methods, however, studies reporting ML for MACE prediction in bariatric surgery remain limited. As such, the objective of this study was to evaluate and compare MACE prediction models in bariatric surgery using traditional statistical methods and ML. METHODS: Cross-sectional study of the MBSAQIP database, from 2015 to 2019. A binary-outcome MACE prediction model was generated using three different modeling methods: (1) main-effects-only logistic regression, (2) neural network with a single hidden layer, and (3) XGBoost model with a max depth of 3. The same set of predictor variables and random split of the total data (50/50) were used to train and validate each model. Overall performance was compared based on the area under the receiver operating curve (AUC). RESULTS: A total of 755,506 patients were included, of which 0.1% experienced MACE. Of the total sample, 79.6% were female, 47.8% had hypertension, 26.2% had diabetes, 23.7% had hyperlipidemia, 8.4% used tobacco within 1 year, 1.9% had previous percutaneous cardiac intervention, 1.2% had a history of myocardial infarction, 1.1% had previous cardiac surgery, and 0.6% had renal insufficiency. The AUC for the three different MACE prediction models was: 0.790 for logistic regression, 0.798 for neural network and 0.787 for XGBoost. While the AUC implies similar discriminant function, the risk prediction histogram for the neural network shifted in a smoother fashion. CONCLUSION: The ML models developed achieved good discriminant function in predicting MACE. ML can help clinicians with patient selection and identify individuals who may be at elevated risk for MACE after bariatric surgery.

RESUMEN

BACKGROUND: Current evidence recommends dietary counselling with a registered dietitian (RD) for successful weight loss after metabolic bariatric surgery; however, there are limited data on the effect of RD follow-ups on micronutrient deficiencies. This study evaluated the effects of the number of postoperative RD visits on nutritional outcomes, including weight loss and micronutrient deficiencies. OBJECTIVES: The aim of this study was to evaluate the effects of the number of postoperative registered dietitian visits on nutritional outcomes, including weight loss and micronutrient deficiencies after metabolic and bariatric surgery. SETTING: Cleveland Clinic Abu Dhabi, United Arab Emirates METHODS: This retrospective study included patients who underwent bariatric surgery between September 2015 and June 2020. Demographics, weight loss, micronutrients, and the number of postoperative RD visits were evaluated. Baseline and 12-month postsurgery outcomes were compared based on the number of RD follow-ups. RESULTS: A total of 174 primary and 46 revisions were included. Patients were 73.6% female, with a mean age of 40 years. The initial mean body mass index was 42.8 kg/m2. Number of RD visits were as follows: 0-1 (39 patients), 2 (59 patients), 3 (55 patients), and 4 or more (67 patients). Baseline (pre-operative) micronutrient values were within normal range. In comparison with the reference group (REF = 0-1 post-op RD visits), patients with 3 RD visits had 7% higher total body weight loss (P < .001) and maintained micronutrients within the normal range at 12 months postoperative. Mean differences in postoperative values were statistically significant (P < .05) for weight, vitamin B12, and vitamin D but not for hemoglobin, ferritin, calcium, folate, vitamin B1, copper, and zinc. CONCLUSION: Our study suggests that three or more RD visits during the first 12 months after bariatric surgery are associated with improved outcomes, including significant percent total body weight loss and lower rates of micronutrient deficiencies.

RESUMEN

COVID-19 pandemic hampered operational efficiency of heart transplant (HT) programs worldwide. Little is known about the global and country-specific changes in HT volumes during the pandemic years 2020-2021. We aimed to describe the global and country-level impact of the COVID-19 pandemic on HT volumes in 2020-2021. This is a cross-sectional study of the Global Observatory on Donation and Transplantation, including the years 2019-2021. Among 60 countries that reported HT data in the years 2019-2020, we analyzed 52 countries with ≥1 transplant during each year. Overall, the number of HTs decreased during 2020 by 9.3% (1.82 to 1.65 PMP). While 75% (n = 39/52) of countries experienced a decrease in HT volumes in 2020, volumes were maintained/increased in the remaining countries. Countries with maintained HT volumes had a higher organ donation rate in 2020 compared to those with decreased volumes (P = 0.03), the only significant predictor of change in HT volumes (P = 0.005). In 2021, a 6.6% recovery from the previous year's drop in global HT rate was noticed, reaching 1.76 HT PMP. Only 1 in 5 countries with reduced volumes in 2020 recovered their baseline volumes in 2021. Only 30.8% of countries with maintained volumes in 2020 had continued growth in HT volumes in 2021. The latter group encompassed the United States of America, the Netherlands, Poland, and Portugal. Further work should define underlying causes of this heterogeneity in HT volume during the pandemic. Identifying policies and practices that helped certain countries mitigate the effect of the pandemic on HT activities may help other countries during similar health crises in the future.

RESUMEN

BACKGROUND: Multidisciplinary care models have been associated with improved clinical outcomes and an increase in adherence to guideline-directed medical therapy among patients hospitalized with heart failure (HF). OBJECTIVE: This study aims to evaluate the association between the creation of a multidisciplinary inpatient HF service and patient outcomes at a tertiary care center in the Middle East/ North Africa. METHODS: We used electronic health records to retrospectively identify patients hospitalized for acute HF between June-2015 and June-2018. Patients were categorized by whether they were hospitalized before (n = 71) or after (n = 86) the implementation of a multidisciplinary HF team (HF-MDT), starting on 1/1/2017. The groups were compared for optimal use of guideline-directed medical therapy, hospital length of stay, 30-day hospital readmission, and in-hospital mortality. RESULTS: The creation of the HF-MDT was associated with significantly better adherence to GDMT at discharge (27.5% vs. 55.4%, (OR 3.3, 95% CI [1.65-6.5]), P<0.001), shorter median hospital length of stay (8, IQR [4.8 - 19] vs. 5, IQR [3- 9], P = 0.02) and a reduction in 30-day hospital readmission (26.5% vs. 11%; OR 0.3, 95% CI [0.1-0.8], P = 0.02). However, there was no difference in-hospital mortality (10.5% vs. 3.5%; OR 0.3, 95% CI [0.1-1.2], P = 0.1). CONCLUSIONS: Implementing an HF-MDT in the care of patients hospitalized with HF is associated with better adherence to GDMT on discharge, reduced hospital length of stay, and lower 30-day readmission rates. The current data support the broader adoption of dedicated HF programs in the Middle East to improve outcomes of patients with HF.

RESUMEN

BACKGROUND: When general anesthesia is used for endovascular thrombectomy (EVT) for acute ischemic stroke (AIS), the choice of anesthetic agents for maintenance remains inconclusive. The different effects of intravenous anesthetic and volatiles agents on cerebral hemodynamics are known and may explain differences in outcomes of patients with cerebral pathologies exposed to the different anesthetic modalities. In this single institutional retrospective study, we assessed the impact of total intravenous (TIVA) and inhalational anesthesia on outcomes after EVT. METHODS: We conducted a retrospective analysis of all patients ≥ 18 years who underwent EVT for AIS of the anterior or posterior circulation under general anesthesia. Baseline patient characteristics, anesthetic agents, intra operative hemodynamics, stroke characteristics, time intervals and clinical outcome data were collected and analyzed. RESULTS: The study cohort consisted of 191 patients. After excluding 76 patients who were lost to follow up at 90 days, 51 patients received inhalational anesthesia and 64 patients who received TIVA were analyzed. The clinical characteristics between the groups were comparable. Multivariate logistic regression analysis of outcome measures for TIVA versus inhalational anesthesia showed significantly increased odds of good functional outcome (mRS 0-2) at 90 days (adjusted odds ratio, 3.24; 95% CI, 1.25-8.36; p = 0.015) and a non-significant trend towards decreased mortality (adjusted odds ratio, 0.73; CI, 0.15-3.6; p = 0.70). CONCLUSION: Patients who had TIVA for mechanical thrombectomy had significantly increased odds of good functional outcome at 90 days and a non-significant trend towards decrease in mortality. These findings warrant further investigation with large randomized, prospective trials.

RESUMEN

Background: In response to the COVID-19 pandemic, elective surgical procedures have been delayed. Even with the implementation of surgical societies' recommendations, patient safety remains a concern. This study evaluates the postoperative outcomes in patients undergoing bariatric surgery after reopening (RO) elective surgery during the COVID-19 pandemic. Methods: All patients who underwent bariatric surgery from September 2015 to July 2020 were included. Patients were divided into two cohorts: the pre-COVID-19 (PC) cohort and the RO cohort. Propensity score weighting was used to evaluate postoperative outcomes. Results: Our study included 1076 patients, 1015 patients were in the PC and 61 patients in the RO. Sixty-four percent were female with a mean age of 37 years and median body mass index of 41 kg/m2. There were no statistically significant differences in 30 days perioperative outcomes, including emergency department visits 24.8% PC versus 19.7% RO (p = 0.492), readmission 4.2% PC versus 8.2% RO (p = 0.361), reoperation 2.6% PC versus 0% RO (p = 0.996), and major complications 4.0% PC versus 4.9% RO (p = 0.812). No patients in the RO contracted COVID-19. Conclusions: With the appropriate policies and precautionary measures, there appear to be no differences in the 30-day postoperative outcomes before and during the COVID-19 pandemic.

RESUMEN

BACKGROUND AND AIM: We have previously shown in a retrospective analysis that the plasma thyroid-stimulating hormone (TSH) rises significantly post-Ramadan in levothyroxine-treated hypothyroid patients, possibly as a result of lifestyle alterations and time restrictions during the nonfasting period from dusk until dawn. The aim of this study is to determine the best time to instruct patients to take levothyroxine during Ramadan so as to minimize changes in thyroid function tests during this period. METHODS: In a randomized prospective design, hypothyroid patients taking levothyroxine were randomized to receive instructions to take levothyroxine at one of the following 3 times during Ramadan: (group 1) at dusk 30-min before Iftar meal, (group 2) 3 or more hours after Iftar meal, or (group 3) at dawn 30-min before Suhur meal. Thyroid function tests were performed within 3 months before Ramadan and within 6 weeks post-Ramadan. Data from patients with at least 1 blood test before or after Ramadan were analyzed using mixed-effects regression models. RESULTS: Plasma TSH levels were available at one or more time points for 148 patients, group 1 (n = 50), group 2 (n = 46), and group 3 (n = 52). A statistically significant within-patient increase in plasma TSH was seen in patients at the 25th percentile pre-Ramadan in groups 2 and 3 (p values <0.001), but not in group 1. A statistically significant within-patient decrease in plasma TSH was found in patients at the 75th percentile in group 1 only. For patients at the 50th percentile pre-Ramadan, no statically significant within-patient changes were found, though descriptively, increases in plasma TSH were observed for groups 2 and 3, while a decrease was observed in group 1. CONCLUSIONS: Our data suggest that instructing patients to take levothyroxine at the time of breaking the fast 30 min before the Iftar meal minimizes unfavorable changes in plasma TSH post-Ramadan. In contrast, instructing patients to take levothyroxine 3 h post-Iftar or 30 min before Suhur led to a greater rise in post-Ramadan TSH.

RESUMEN

Background: Data on patient characteristics and provider practices in the management of lipids per the new guidelines in specific secondary prevention patients in the Middle East is limited. Objective: To explore patient characteristics and lipid management practices according to the new cholesterol guidelines in secondary prevention patients, up to one year following discharge for coronary artery bypass graft surgery (CABG). Methods: A retrospective chart review of patients discharged post CABG between February 2017 and February 2018 at a quaternary care centre in the Middle East. Patients were characterized by baseline demographics, comorbidities, and use of lipid lowering medications. Results: 189 patients were included in the analysis. Most were diabetic (70.9%) and classified as very high risk per the ACC/AHA guidelines (84.1%) and as extremely high risk per the AACE guidelines (85.2%). Most patients (93.1%) were discharged on high intensity statin. About one third (28.6%) were never seen or only followed once within the first 2 weeks post discharge. Of those who continued to follow up beyond 3 months and within 1 year of discharge (44.4%), about half (51.2%) had follow-up lipid panels performed. Patients who followed up and were seen by a cardiologist were five times more likely to have lipid panels ordered than those seen solely by a CT surgeon. Of those with follow-up lipid panels beyond 3 months: 59.3% achieved LDL goal of <70 mg/dL and 29% achieved LDL <55 mg/dL based on their respective goals. Conclusions: Most patients undergoing CABG in a quaternary care centre in the Middle East are high risk ASCVD. Nonetheless, lipid goals are not commonly achieved nor routinely monitored. Providers will need to transition from the previous risk stratification and statin-only focused approach to adopt the most recent guidelines.

RESUMEN

INTRODUCTION: Hemodialysis patients frequently suffer from anemia. Proper utilization of therapies such as iron and erythropoiesis-stimulating agents (ESAs) is crucial to attain symptom management and established hemoglobin targets. The purpose of this study was to evaluate the clinical and financial impact of nephrology-trained pharmacists on anemia management in these patients. MATERIALS AND METHODS: A retrospective study of outpatient hemodialysis patients observed between January 2010 and December 2011. In December 2010, pharmacists were tasked to manage anemia under a medical directive. Primary endpoints were compared across years using a mixed-effects model strategy. An unstructured random effects correlation matrix was utilized to capture patient-level variation in 2010 and 2011, separately. RESULTS: Of 202 patients identified, 163 contributed in both years, 57% were males, aged 65.18 ± 16.3 years. Hemoglobin levels were 10.95 ± 0.95 and 10.83 ± 0.94 g/dL in 2010 vs. 2011, respectively (p = 0.158), while the transfusion rate was 1.3% and 1.8%, respectively (p = 0.196). Ferritin levels of 273.5 ± 22 and 317.1 ± 12 ng/mL (p = 0.0019), iron saturation 0.30 ± 0.11 and 0.30 ± 0.05 (p = 0.838), and parenteral iron dose of 215.4 ± 100.2 and 317.1 ± 123.7 mg, respectively (p = 0.996), were identified. Finally, the average weekly ESA dose in 2010 was higher and trending up as compared to 2011 where it significantly trended down. The amount of intravenous erythropoietin alfa was 12,315.6 ± 76 vs. 11,364.1 ± 52 units/week, respectively (p = 0.0556) with expenditure of 2.8 million Canadian dollars in 2010 vs. 2.3 million Canadian dollars in 2011. CONCLUSION: The participation of a nephrology pharmacist resulted in favorable outcomes in dose optimization, decreased expenditure, and positive trends in therapeutic goal achievement.

RESUMEN

OBJECTIVE: The holy month of Ramadan poses a challenge for levothyroxine-treated patients due to altered eating habits and time restrictions. The aim of this study was to examine the impact of lifestyle changes during Ramadan on thyroid function tests in hypothyroid patients taking levothyroxine in the United Arab Emirates. METHODS: Retrospective design whereby levothyroxine-treated hypothyroid patients who had thyroid function tests within 3 months pre-Ramadan and within 2 months post-Ramadan were included. We looked at adherence to levothyroxine, eating pattern, and levothyroxine administration in relation to meal times during Ramadan. Pre- and post-Ramadan thyroid function tests and the potential impact of independent variables using a random-intercept mixed effects linear model were examined. RESULTS: A total of 112 patients (89 females) were recruited in the study, with a mean age ± standard error (SE) of 44.70±1.36 years (range, 19.0 to 79.0 years). The mean thyroid-stimulating hormone (TSH) within 3 months before Ramadan was 1.809±0.094 mIU/L (median, 41.5 days; interquartile range [IQR], 25.0 to 73.0 days), while the mean TSH within 2 months post-Ramadan was higher at 3.072±0.312 mIU/L (median, 27.5 days; IQR, 14.0 to 42.0 days). Post-Ramadan, 36 out of 112 patients had a plasma TSH outside of the normal reference range. The independent variable outcomes model showed that older patients and males were more likely to have an increased plasma TSH post-Ramadan. There was no relationship between the time of levothyroxine administration and change in TSH level. CONCLUSION: Levothyroxine-treated hypothyroid patients showed a significant increase in plasma TSH post-Ramadan, amounting to 2.525 standard deviations, with older patients and males more likely to be affected. ABBREVIATIONS: IQR = interquartile range; T4 = thyroxine; TSH = thyroid-stimulating hormone.

RESUMEN

INTRODUCTION: The ultrasound-guided axillary vein is becoming a compulsory alternative vessel for central venous catheterization and the anatomical position offers several potential advantages over blind, subclavian vein techniques. OBJECTIVE: To determine the degree of dynamic variation of the axillary vein size measured by ultrasound prior to the induction of general anesthesia and after starting controlled mechanical ventilation. DESIGN: Prospective, observational study. METHODS: One hundred ten patients undergoing elective surgery were enrolled and classified according to sex, age, and body mass index. Two-dimensional cross-sectional vein diameter, area, and mean flow velocity were performed using ultrasound on both the left and right axillary veins of each subject before and after induction of anesthesia. RESULTS: There was statistically significant evidence showing that the axillary vein area increases when patients are mechanically ventilated. When considering venous flow velocity as a primary outcome, velocity decreased after patients moved from spontaneous to mechanical ventilation (coefficient = -0.267), but this relationship failed to achieve statistical significance (t = -1.355, p = 0.179). CONCLUSIONS: Anatomical variations in depth and diameter as well as the collapsibility due to intrathoracic pressures changes represent common challenges that face clinicians during central venous catheterization of the axillary vein. A noteworthy increase in vessel size as patients transition from spontaneous to mechanical ventilation may theoretically improve first-pass cannulation success with practitioners skilled in both ultrasound and procedure. As a result, placing a centrally inserted central catheter after the induction of anesthesia may be beneficial.

RESUMEN

BACKGROUND: Vaccination is the primary strategy to reduce the burden of human papillomavirus (HPV) related diseases in the United States. Unvaccinated youth are at risk for HPV infection and associated diseases, and limited research has explored factors associated with HPV vaccination among those who are disadvantaged and at high risk, including lesbian, gay, bisexual, transgender and queer and/or homeless. METHODS: A retrospective electronic medical record review was conducted at an urban, homeless, and lesbian, gay, bisexual, transgender and queer focused health center in northeastern US logistic regression models examined the associations between HPV vaccination and demographic/social characteristics and health behaviors. RESULTS: A total of 1211 men and 1326 women (gender at birth) records were reviewed from patients (ages 13-26 years) who presented for care between January 2010 and June 2013. The sample was diverse, and about half identified as heterosexual and reported stable/secure housing. Approximately 8% of men and 29% of women had obtained ≥ 1 HPV vaccine dose. The strongest predictors of vaccine initiation were health-related behaviors: having an annual examination, obtaining a non-HPV vaccine, and engaging in oral sex. Additionally, for women only, having had a Pap test or a sexually transmitted infection visit were also associated with an increase in odds, whereas identifying as transmale decreased the odds of vaccination. Having private insurance was the only predictor of 3-dose completion (women only). CONCLUSIONS: Among a high-risk adolescent sample, primarily health-seeking behaviors increased the odds of HPV vaccination, reinforcing the importance of providers using various routine preventative visits as opportunities/cues to vaccine.

BACKGROUND AND PURPOSE: To describe the availability of human papillomavirus (HPV) and HPV vaccine information accessible to college students via official college and university websites. METHODS: A review and analysis of HPV and HPV vaccination information abstracted from a national sample (n = 214) of college/university websites. Three abstractors systematically evaluated quality and quantity of vaccination, sexual health, and HPV disease information from health service webpages. CONCLUSIONS: The majority of colleges/universities had designated student health service webpages (n = 181). Of these, 86% provided information on vaccinations, but less than 50% mentioned HPV or the HPV vaccine specifically and only 32% provided any HPV educational information. Colleges/university webpages that provide sexual health and or general vaccination information had higher odds of providing information on HPV and HPV vaccination. IMPLICATIONS FOR PRACTICE: Nurse practitioners who care for college-aged persons need to be cognizant of the many ways they can promote HPV vaccination. Providing accurate information about resources available at student health centers is a way to promote health on campus; the findings from this study indicate that HPV and HPV vaccine information may be lacking on many college/university websites.

RESUMEN

INTRODUCTION: Female college students, aged 18-25 years, are at high risk for sexual violence compared with women of other age groups. Lack of clear consent is a preceding and defining component of forced sex and sexual violence. This study explored the association between sexual consent awareness, attitudes, and beliefs and a history of forced sex among a sample of college women. In addition, the level of alcohol use among this group was examined. METHODS: A cross-sectional electronic survey was sent to approximately 5900 female students enrolled at a large public university in the northeastern United States. Sexual consent was measured with the Sexual Consent Scale-Revised, and alcohol use was measured with the Alcohol Use Disorders Identification Test-Consumption Items. Logistic regression models were used to examine the differences in sexual consent scores based on a history of forced sex. RESULTS: The final sample included 925 students. Twenty-two percent of participants reported a history of forced sex; more than half (59%) reported alcohol use before sexual activity. Women with greater awareness of sexual consent were significantly more likely to have a history of forced sex. Women who utilize more nonverbal, indirect approaches to communicating sexual consent were significantly less likely to have a history of forced sex compared with women with no history of forced sex. DISCUSSION: These findings highlight high rates of forced sex and alcohol use in a sample of college women and explicate sexual consent awareness and communication behaviors associated with a history of forced sex.

RESUMEN

INTRODUCTION: Intimate partner violence (IPV) is associated with risk of sexually transmitted infections (STIs) and HIV among women, but less is known about mechanisms of this association and if length of relationship violence is a factor. The purpose of this study was to explore the relationship between the duration of IPV and both individual and partner-related sexual risk factors that may increase women's risk for STIs and HIV. METHODS: This was a secondary analysis of data collected from the medical records of 2000 women. Four distinct categories defined the duration of partner violence: violence in the past year only, past year and during the past 5 years, past year plus extending for greater than 5 years, and no past year violence but a history of partner violence. Logistic regression models were used to examine the associations between the duration of partner violence and individual sexual risk behaviors (eg, number of sexual partners, drug and/or alcohol use, anal sex) and partner-related sexual risk factors (eg, nonmonogamy, STI risk, condom nonuse). RESULTS: Nearly 30% of the women in the study reported a history of partner violence during their lifetime. All of the individual risk factors, as well as partner-related risk factors, were significantly associated (P < .05) with partner violence and duration of violence. DISCUSSION: The study findings extend the knowledge related to partner violence as a risk factor for STIs/HIV, highlighting the effects of partner violence duration on the health of women. Assessing for lifetime experiences of partner violence may improve outcomes for women and their families.

RESUMEN

BACKGROUND: Partner violence may interfere with a woman's ability to maintain continuous contraception and therefore contribute to increased risk of pregnancy among childbearing women. STUDY DESIGN: A retrospective review of medical records (N=2000) was conducted from four family planning clinics in the northeast United States. Eligibility criteria for inclusion were as follows: (1) female, (2) reproductive age (menarche through menopause), (3) seeking reproductive services and (4) clinic visit for annual gynecologic exam between 2006 and 2011. RESULTS: Partner violence was documented in 28.5% (n=569) of medical records. Chronicity of violence influenced contraceptive patterns and pregnancy risk. Women reporting past year partner violence only [odds ratio (OR)=10.2] and violence during the last 5 years (OR=10.6) had the highest odds of not using a current method of contraception. Women reporting recent exposure to violence were most likely to change birth control methods and use emergency contraception (OR=6.5). Women experiencing any history of violence reported more frequent contraceptive method changes during the previous year. CONCLUSIONS: A history of partner violence was common among women utilizing family planning services. The chronicity of violence appeared to play a significant role in contraceptive method changes, types of methods used and pregnancy risk. These results may be one explanation for increased pregnancies among women who experience partner violence.
