ObjectiveTo explore the factors that influence institutional care for the disabled elderly in China and the key factors that influence individuals based on the Andersen model.DesignCross-sectional survey.SettingThe research was conducted in 18 cities in Henan Province, China.Main outcome measuresA multistage, stratified sampling design was employed. The χ2test was used to compare the differences in basic information of the disabled elderly. A binary Logit model was used to examine the factors influencing the willingness to institutionalise elderly people with disabilities. The determinants of willingness to care in an institution were also explored in a stratified study by gender, age and region to identify the key differences affecting institutionalisation. The Andersen model was used as the theoretical framework to infer the impact strength of each model.ResultsOf the 2810 disabled elderly people in Henan, China, 7.4% of the elderly had a willingness for institutional care. In the binary logistic regression analysis, whether living alone (OR (95% CI)=0.596 (0.388 to 0.916)), medical payment method (basic medical insurance for urban employees: OR (95% CI)=2.185 (1.091 to 4.377)), having mental illness (OR (95% CI)=2.078 (1.044 to 4.137)) had a statistically significant difference (pConclusionsSeveral factors influence the willingness of the disabled elderly to institutionalise. Therefore, it is recommended that relevant authorities take targeted measures to focus on the disabled elderly to identify more precise elderly care services to deal with the ageing crisis.

A kV imager coupled to a novel, ring-gantry radiotherapy system offers improved on-board kV-cone-beam computed tomography (CBCT) acquisition time (17-40 seconds) and image quality, which may improve CT radiotherapy image-guidance and enable online adaptive radiotherapy. We evaluated whether inter-observer contour variability over various anatomic structures was non-inferior using a novel ring gantry kV-CBCT (RG-CBCT) imager as compared to diagnostic-quality simulation CT (simCT).Seven patients undergoing radiotherapy were imaged with the RG-CBCT system at breath hold (BH) and/or free breathing (FB) for various disease sites on a prospective imaging study. Anatomy was independently contoured by seven radiation oncologists on: 1. SimCT 2. Standard C-arm kV-CBCT (CA-CBCT), and 3. Novel RG-CBCT at FB and BH. Inter-observer contour variability was evaluated by computing simultaneous truth and performance level estimation (STAPLE) consensus contours, then computing average symmetric surface distance (ASSD) and Dice similarity coefficient (DSC) between individual raters and consensus contours for comparison across image types.Across 7 patients, 18 organs-at-risk (OARs) were evaluated on 27 image sets. Both BH and FB RG-CBCT were non-inferior to simCT for inter-observer delineation variability across all OARs and patients by ASSD analysis (p 0.001), whereas CA-CBCT was not (p = 0.923). RG-CBCT (FB and BH) also remained non-inferior for abdomen and breast subsites compared to simCT on ASSD analysis (p 0.025). On DSC comparison, neither RG-CBCT nor CA-CBCT were non-inferior to simCT for all sites (p 0.025).Inter-observer ability to delineate OARs using novel RG-CBCT images was non-inferior to simCT by the ASSD criterion but not DSC criterion.

Objectives There are limited methods to identify which obese patients will experience wound complications after undergoing gynecologic surgery. We sought to determine the association between frailty and postoperative wound complications and to develop a prediction model for wound complications in this patient population. Methods We reviewed prospectively collected data of obese patients undergoing laparotomy though midline vertical incisions from 7/2013-3/2016. Modified frailty index (mFI) was calculated using 11 comorbidities previously validated. The primary outcome was the composite rate of postoperative wound complication. Data was analyzed using Fisher exact test or Chi-square and t-tests or Kruskal-Wallis tests. Poisson regression models were used to generate relative risks. Prediction models were created with receiver-operator characteristic curve analysis. Results Of 163 patients included, 56 (34%) were considered frail. Wound complications occurred in 52 patients (31.9%): 28 (50%) frail and 24 (22.4%) non-frail patients (RR 2.23, 95%CI 1.29-3.85). Frail patients had significantly greater frequencies of wound breakdown (37.5% vs 15%, RR 2.51, 95%CI 1.31-4.81). After controlling for BMI, tobacco use, and maximum postoperative glucose, frailty remained an independent predictor of wound complication (aRR 1.88, 95%CI 1.04-3.40). The area under the curve for the predictive model incorporating frailty was 0.73 for wound complications. Conclusion Frailty is associated with wound complications in obese patients undergoing gynecologic surgery via a midline vertical incision and is a useful tool in identifying the most high risk patients. Further prospective research is necessary to incorporate mFI into preoperative planning and counseling.

We aim to describe survival outcomes of gynecologic oncology inpatients treated with intravenous bisphosphonates for hypercalcemia and develop a risk stratification model that predicts decreased survival to aid with goals of care discussion. In a single-center, retrospective cohort study of gynecologic oncology patients admitted for bisphosphonate therapy for hypercalcemia. Survival from hypercalcemia to death was assessed by Kaplan-Meier method and log-rank test. Univariate log-rank test and Cox proportional hazards modeling were used to develop a risk stratification model. Sixty-five patients were evaluable with a median follow-up of 83.5 months. Mean age was 59.2 years, 64.6% had recurrent disease, and 30.8% had ≥2 previous lines of chemotherapy. Median survival was 38 days. Our analysis identified four risk factors (RFs) [brain metastasis, >1 site of metastasis, serum corrected peak calcium >12.4 (mg/dL), and peak ionized calcium >5.97 (mg/dL)] that predicted survival and were used to build a risk stratification score. Sum of RFs included 35 patients with 1 RF, 11 had 2 RFs, and 19 had ≥3 RF. Median survival for 1, 2, or ≥ 3 RFs was 53, 28, and 26 days respectively (p = .009). Survival at 6 months was 28.6%, 18.2%, and 5.3% for each group respectively. Hospice enrollment was 26.2%, and did not vary by group (p = .51). Among gynecologic oncology patients, inpatient management of hypercalcemia with bisphosphonates portends poor prognosis. Individualized risk stratification may help guide end-of-life discussions and identify patients who may benefit most from hospice care., Highlights • Inpatient treatment of hypercalcemia in gynecologic malignancies portends poor survival. • Brain metastases, >1 metastatic site, and corrected peak or ionized calcium predict mortality. • Our risk stratification can identify appropriate hospice candidates.

Background Adaptive magnetic resonance imaging‐guided radiation therapy (MRgRT) can escalate dose to tumors while minimizing dose to normal tissue. We evaluated outcomes of inoperable pancreatic cancer patients treated using MRgRT with and without dose escalation. Methods We reviewed 44 patients with inoperable pancreatic cancer treated with MRgRT. Treatments included conventional fractionation, hypofractionation, and stereotactic body radiation therapy. Patients were stratified into high‐dose (biologically effective dose [BED10] >70) and standard‐dose groups (BED10 ≤70). Overall survival (OS), freedom from local failure (FFLF) and freedom from distant failure (FFDF) were evaluated using Kaplan‐Meier method. Cox regression was performed to identify predictors of OS. Acute gastrointestinal (GI) toxicity was assessed for 6 weeks after completion of RT. Results Median follow‐up was 17 months. High‐dose patients (n = 24, 55%) had statistically significant improvement in 2‐year OS (49% vs 30%, P = 0.03) and trended towards significance for 2‐year FFLF (77% vs 57%, P = 0.15) compared to standard‐dose patients (n = 20, 45%). FFDF at 18 months in high‐dose vs standard‐dose groups was 24% vs 48%, respectively (P = 0.92). High‐dose radiation (HR: 0.44; 95% confidence interval [CI]: 0.21‐0.94; P = 0.03) and duration of induction chemotherapy (HR: 0.84; 95% CI: 0.72‐0.98; P = 0.03) were significantly correlated with OS on univariate analysis but neither factor was independently predictive on multivariate analysis. Grade 3+ GI toxicity occurred in three patients in the standard‐dose group and did not occur in the high‐dose group. Conclusions Patients treated with dose‐escalated MRgRT demonstrated improved OS. Prospective evaluation of high‐dose RT regimens with standardized treatment parameters in inoperable pancreatic cancer patients is warranted.

Preclinical studies have suggested promising activity for the combination of disulfiram and copper (DSF/Cu) against glioblastoma (GBM) including re-sensitization to temozolomide (TMZ). A previous phase I study demonstrated the safety of combining DSF/Cu with adjuvant TMZ for newly diagnosed GBM. This phase II study aimed to estimate the potential effectiveness of DSF/Cu to re-sensitize recurrent GBM to TMZ. This open-label, single-arm phase II study treated recurrent TMZ-resistant GBM patients with standard monthly TMZ plus concurrent daily DSF 80 mg PO TID and Cu 1.5 mg PO TID. Eligible patients must have progressed after standard chemoradiotherapy and within 3 months of the last dose of TMZ. Known isocitrate dehydrogenase (IDH) mutant or secondary GBMs were excluded. The primary endpoint was objective response rate (ORR), and the secondary endpoints included progression-free survival (PFS), overall survival (OS), clinical benefit (response or stable disease for at least 6 months), and safety. From March 2017 to January 2018, 23 recurrent TMZ-resistant GBM patients were enrolled across seven centers, and 21 patients were evaluable for response. The median duration of DSF/Cu was 1.6 cycles (range: 0.1–12.0). The ORR was 0%, but 14% had clinical benefit. Median PFS was 1.7 months, and median OS was 7.1 months. Only one patient (4%) had dose-limiting toxicity (grade three elevated alanine transaminase). Addition of DSF/Cu to TMZ for TMZ-resistant IDH-wild type GBM appears well tolerated but has limited activity for unselected population.

To determine how obstetricians and gynecologists (OB/GYNs) perceive the gynecologic health effects of obesity and to identify perceived obstacles to counseling. OB/GYNs with 3 St. Louis health systems were emailed a 46-question survey regarding physicians' role in counseling women on the health risks of obesity and barriers faced in achieving this counseling. Differences between respondents' gender, age, practice type, years in practice, and body mass index were assessed using Chi-square or Fisher's exact tests as appropriate. Of 318 OB/GYNs emailed, 134 completed surveys, including 82 generalists and 52 subspecialists. 93% of respondents believed it was necessary to educate patients on health risks of obesity. 90% and 75%, respectively, cited diagnoses of endometrial hyperplasia and cancer as teachable moments for counseling. The most frequently cited barriers to successful counseling were lack of time, referral services, and patient tools/information. Most did not believe they had adequate reimbursement (65%), training (53%) or educational resources (50%) to counsel patients. Survey answers differed by practice setting, gender, and provider age. Although most OB/GYN providers consider obesity counseling important, execution is hindered by perceived barriers that differ by provider gender, age, and practice type. For OB/GYNs, more effective weight management counseling will require better training and practice-specific strategies. Based on survey responses, better reimbursement combined with increased resources for appropriate referrals and cancer prevention counseling are needed in order to improve weight management implementation in OB/GYN.

Objective To estimate the risk of perioperative morbidity with increasing number of cesareans. Study Design We conducted a retrospective cohort study from 2004 to 2010. Patients delivered by cesarean were included. Outcome measures were a composite organ injury (bowel or bladder), hysterectomy, hemorrhage requiring transfusion, severe morbidity, or surgical site complications. The Cochran–Armitage's test of trend was used to assess increasing incidence of each morbidity with number of prior cesareans. Multivariable logistic regression was used to estimate adjusted risks for each morbidity with increasing number of cesareans compared with primary cesarean. Results Of the 15,872 women in the cohort, 5,144 had cesarean delivery: 3,113 primary, 1,310 one prior, 510 two prior, and 211 three or more prior cesareans. There was a significant increase in organ injury, hysterectomy, and surgical site complications with increasing number of cesareans. In multivariable analysis, the risk of organ injury and hysterectomy was increased compared with primary cesarean after two prior cesareans, and after three or more cesareans for hemorrhage requiring transfusion and surgical site complications. Conclusion The risks of organ injury and hysterectomy are increased after two or more prior cesareans, and risks of hemorrhage and surgical site complications are increased after three or more cesareans.

Objectives We compared HPV vaccine initiation and completion of heterosexual with lesbian and bisexual (LB) women. Methods We aggregated National Health and Nutrition Examination Survey data from 2009 to 2016 for 3,017 women aged 18 to 34 y in the United States. HPV vaccine initiation was defined as reported receipt of ≥1 dose of the vaccine and completion as receipt of the three recommended doses. Weighted percentages and multivariable logistic regression models were used to examine differences in HPV vaccine initiation and completion between heterosexual and LB women. Results Approximately 12% of respondents self-identified as LB women. Overall, a higher percentage of respondents (26%) had initiated the HPV vaccine than completed the three vaccine doses (17%). In the bivariate analysis, LB women had higher initiation ([35% of LB women versus 25% heterosexual]; p = .0012) and completion rates ([24% of LB women versus 17% heterosexual]; p = .0052) than heterosexual women. After adjusting for covariates, compared to heterosexual women, LB women were 60% (aOR = 1.60, 95% CI: 1.16-2.19) more likely to initiate and 63% (aOR = 1.63, 95% CI: 1.12-2.37) more likely to complete the HPV vaccine. Conclusions Although LB women had higher likelihood of HPV vaccine initiation and completion compared with heterosexual women, their HPV vaccine uptake was well below the Healthy People 2020 target (80%). Understanding differences in the drivers of vaccine uptake in the LB population may inform strategies that would further increase HPV vaccine uptake toward achieving the 80% completion target.

IntroductionMetastatic involvement of groin nodes can alter radiation therapy planning for pelvic tumors. 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) can identify nodal metastases; however, interpretation of PET/CT-positive nodes can be complicated by non-malignant processes. We evaluated quantitative metrics as methods to identify groin metastases in patients with pelvic tumors by comparison with standard subjective interpretive criteria, with pathology as the reference standard.MethodsWe retrospectively identified patients with vulvar, vaginal, or anal cancers who underwent 18F-FDG PET/CT before pathologic evaluation of groin nodes between 2007 and 2017. Because patho-radiologic correlation was not possible for every node, one index node identified on imaging was selected for each groin. For each index node, standardized uptake value measurements, total lesion glycolysis, metabolic tumor volume, CT-based volume, and short and long axes were measured. Multivariate logistic regression was used to identify metrics predictive for pathologically positive groins and generate a probabilistic model. Area under the receiver-operating characteristic curves (AUCs) for the model were compared with clinical interpretation from the diagnostic report via a Wald’s χ2 test.ResultsOf 55 patients identified for analysis, 75 groins had pathologic evaluation resulting in 75 index groin nodes for analysis with 35 groins pathologically positive for malignancy. Logistic regression identified mean standardized-uptake-value (50% threshold) and short-axis length as the most predictive imaging metrics for metastatic nodal involvement. The probabilistic model performed better at predicting pathologic involvement compared with standard clinical interpretation on analysis (AUC 0.91, 95% CI 0.84 to 0.97 vs 0.80, 95% CI 0.71 to 0.89; pDiscussionAccuracy of 18F-FDG PET/CT for detecting groin nodal metastases in patients with pelvic tumors may be improved with the use of quantitative metrics. Improving prediction of nodal metastases can aid with appropriate selection of patients for pathologic node evaluation and guide radiation volumes and doses.

Objectives: Gynecologic oncologists frequently care for patients at the end of life with the aid of palliative care (PC) specialists. Our primary objectives were to identify perceived barriers to integrating specialty PC into gynecologic cancer care. Materials and Methods: Members of the Society of Gynecologic Oncology (SGO) were invited to participate in an anonymous online survey. A Likert scale captured perceptions regarding primary and specialty PC, frequent barriers to use of PC, and potential interventions. Results: A total of 174 (16%) gynecologic oncologists completed the survey. The majority (75%) agreed or strongly agreed that PC should be integrated into cancer care at diagnosis of advanced or metastatic cancer. The most frequently perceived PC barriers included patients’ unrealistic expectations (54%), limited access to specialty PC (25%), poor reimbursement (25%), time constraints (22%), and concern of reducing hope or trust (21%). The most agreed upon potential intervention was increased access to outpatient PC (80%). Conclusions: According to this cohort of SGO members, families’ or patients’ unrealistic expectations are the most frequent barriers to specialty PC. Understanding this communication breakdown is critically important.

Importance Two-thirds of women in labor receive supplemental oxygen to reverse perceived fetal hypoxemia and prevent acidemia. Oxygen is routinely administered for category II fetal heart tracings, a class of fetal tracing used to designate intermediate risk for acidemia. This liberal use of oxygen may not be beneficial, particularly because neonatal hyperoxygenation is harmful. Objective To test the hypothesis that room air is noninferior to oxygen in improving fetal metabolic status among patients with category II fetal heart tracings. Design, Setting, and Participants This was a randomized, unblinded noninferiority clinical trial conducted between June 2016 and July 2017 in the labor and delivery ward of a single tertiary care center. Women with singleton pregnancies at 37 weeks’ gestational age or more who were admitted for delivery were eligible. Of those who met inclusion criteria, the patients who developed category II tracings in labor that necessitated intrauterine resuscitation were randomized in a 1:1 ratio to room air or oxygen. Analyses were intention-to-treat. Interventions The oxygen group received 10 L of oxygen per minute by nonrebreather facemask until delivery. The room air group was exposed to room air only without a facemask. Main Outcomes and Measures The primary outcome was umbilical artery lactate, a marker of metabolic acidosis and neonatal morbidity. Noninferiority was defined as a mean difference between groups of less than 9.0 mg/dL (1.0 mmol/L). Secondary outcomes were other umbilical artery gases, cesarean delivery for nonreassuring fetal status, and operative vaginal delivery. Results Of the 705 patients who met inclusion criteria, 277 (39.3%) were enrolled on admission. During labor, 114 patients (41.2% of the enrolled patients) developed category II tracings and were randomized to room air (57 patients; 50.0% of the randomized patients) or oxygen (57 patients; 50.0% of the randomized patients). A total of 99 patients (86.8% of the randomized patients) with paired cord gases were included in the modified intention-to-treat analysis. The 99 patients included 76 African American women (77%); mean (SD) age was 27.3 (6.3) years in the oxygen group and 27.8 (5.3) years in the room air group. There was no difference in umbilical artery lactate between the group on oxygen and the group on room air (mean, 30.6 mg/dL [95% CI, 27.0 to 34.2 mg/dL] vs 31.5 mg/dL [95% CI, 27.9 to 36.0 mg/dL]);P = .69). The mean difference in lactate was 0.9 mg/dL (95% CI, −4.5 to 6.3 mg/dL), which was within the noninferiority margin. There was no difference in other umbilical artery gas components or mode of delivery between groups. Conclusions and Relevance Among patients with category II fetal heart tracings, intrauterine resuscitation with room air is noninferior to oxygen in improving umbilical artery lactate. The results of this trial challenge the efficacy of a ubiquitous obstetric practice and suggest that room air may be an acceptable alternative.

Daily rhythms generated by endogenous circadian mechanisms and synchronized to the light-dark cycle have been implicated in the timing of birth in a wide variety of species. Although chronodisruption (e.g., shift work or clock gene mutations) is associated with poor reproductive outcomes, little is known about circadian timing during pregnancy. This study tested whether daily rhythms change during full-term pregnancies in mice and women. We compared running wheel activity continuously in both nonpregnant ( n = 14) and pregnant ( n = 13) 12- to 24-week-old C57BL/6NJ mice. We also monitored wrist actigraphy in women ( N = 39) for 2 weeks before conception and then throughout pregnancy and measured daily times of sleep onset. We found that on the third day of pregnancy, mice shift their activity to an earlier time compared with nonpregnant dams. Their time of daily activity onset was maximally advanced by almost 4 h around day 7 of pregnancy and then shifted back to the nonpregnant state approximately 1 week before delivery. Mice also showed reduced levels of locomotor activity during their last week of pregnancy. Similarly, in women, the timing of sleep onset was earlier during the first and second trimesters (gestational weeks 4-13 and 14-27) than before pregnancy and returned to the prepregnant state during the third trimester (weeks 28 until delivery). Women also showed reduced levels of locomotor activity throughout pregnancy. These results indicate that pregnancy induces changes in daily rhythms, altering both time of onset and amount of activity. These changes are conserved between mice and women.

BACKGROUND: Recommendations on preventing the primary cesarean delivery removed the previously defined time limits for latent labor (defined as ending at 6 cm) and urged clinicians to avoid cesarean delivery for labor abnormalities in the latent phase. However, relatively little is known about the implications of labor curve abnormalities from 4 cm to 6 cm and subsequent outcomes. OBJECTIVE: To examine the association between length of time for dilation from 4 cm to 6 cm, delivery outcomes, and maternal and neonatal morbidity. STUDY DESIGN: This is a secondary analysis of a prospective cohort study of patients at ≥37 weeks presenting in spontaneous or induced labor with a non-anomalous living singleton in vertex presentation. Patients with a history of cesarean delivery or who did not achieve 6 cm dilation were excluded. We used interval censored regression to determine the 90(th)percentile for dilation time from 4 cm to 6 cm and used logistic regression to estimate the odds ratios and 95% confidence intervals for adverse outcomes for patients above the these cutoffs percentile compared to those at or below. Analyses were adjusted for obesity, nulliparity, race, hypertension, diabetes, and type of labor (induced vs. spontaneous/augmented). Outcomes included cesarean delivery, maternal morbidity (composite of postpartum fever, wound infection, hemorrhage), and neonatal morbidity (composite of neonatal death, hypothermic therapy, mechanical ventilation, respiratory distress, meconium aspiration syndrome, seizure, or treatment of sepsis). Additionally, we created receiver operator characteristic curves to predict cesarean delivery, and maternal and neonatal morbidity based on time to dilate from 4 cm to 6 cm. The cutoff for time for each outcome was identified using the Youden index to maximize sensitivity and specificity, and test characteristics were computed. RESULTS: There were 7,355 patients eligible for analysis, 728 (10%) had dilation times from 4 cm to 6 cm >10.3 hours, which was the 90(th) percentile, and 6627 (90%) had dilation times ≤ 10.3 hours. Having dilation time from 4 cm to 6 cm above the 90(th) percentile (10.3 h) was associated with cesarean (adjusted odds ratio 2.05 (95% confidence interval 1.67, 2.52)), composite maternal morbidity (adjusted odds ratio 1.48 (95% confidence interval 1.10, 2.00)), and composite neonatal morbidity (adjusted odds ratio 1.92 (95% confidence interval 1.52, 2.4.)). The area under the receiver operator characteristic curve for predicting cesarean delivery was 0.73 (95% confidence interval 0.71, 0.75). The test characteristics for the cutoff of 9.75 h were: sensitivity 68.3% (95% confidence interval 64.8%, 71.7%), specificity 66.2% (95% confidence interval (55.0%, 67.3%), positive predictive value 18.5% (95% confidence interval 17.1%, 20.0%), and negative predictive value 94.9% (95% confidence interval 94.2%, 95.5%). For composite maternal morbidity the cutoff was 6.98 hours and the area under the curve was 0.62 (95% confidence interval 0.59, 0.65), while for composite neonatal morbidity it was 5.5 hours (area under the curve 0.69, 95% confidence interval 0.67, 0.71). CONCLUSIONS: Patients whose dilation time from 4 cm to 6cm exceeds the 90(th) percentile have increased odds of cesarean delivery and postpartum complications. Prolonged dilation time has moderate predictive ability for adverse outcomes. Future studies should investigate at what point, if any, intervention is warranted during this period to reduce these risks.

Objective To investigate whether an early 3-week postpartum visit in addition to the standard 6-week visit increases long-acting reversible contraception (LARC) initiation by 8 weeks postpartum compared to the routine 6-week visit alone. Study design We enrolled pregnant and immediate postpartum women into a prospective randomized, non-blinded trial comparing a single 6-week postpartum visit (routine care) to two visits at 3 and 6 weeks postpartum (intervention), with initiation of contraception at the 3-week visit, if desired. All participants received structured contraceptive counseling. Participants completed surveys in-person at baseline and at the time of each postpartum visit. A sample size of 200 total participants was needed to detect a 2-fold difference in LARC initiation (20% vs. 40%). Results Between May 2016 and March 2017, 200 participants enrolled; outcome data are available for 188. The majority of LARC initiation occurred immediately postpartum (25% of the intervention arm and 27% of the routine care arm). By 8 weeks postpartum, 34% of participants in the intervention arm initiated LARC, compared to 41% in the routine care arm (p=.35). Overall contraceptive initiation by 8 weeks was 83% and 84% in the intervention and routine care arms, respectively (p=.79). There was no difference between the arms in the proportion of women who attended at least one postpartum visit (70% vs. 74%, p=.56). Conclusion The addition of a 3-week postpartum visit to routine care does not increase LARC initiation by 8 weeks postpartum. The majority of LARC users desired immediate rather than interval postpartum initiation. Clinical trial registration Clinicaltrials.gov NCT02769676 Implications The addition of a 3-week postpartum visit to routine care does not increase LARC or overall contraceptive initiation by 8 weeks postpartum when the option of immediate postpartum placement is available. The majority of LARC users desired immediate rather than interval postpartum initiation.

PURPOSE: To determine if dynamic susceptibility-weighted perfusion magnetic resonance imaging (DSC-PMR) can be used to predict local recurrence (LR) of brain metastases after stereotactic radiosurgery (SRS). METHODS: This is a prospective observational study of adult brain metastasis patients treated with single-fraction SRS, who were imaged with DSC-PMRs before SRS and after 1 week. DSC-PMRs were performed with tracer method in which injection of gadolinium was followed by repeated T2*-weighted gradient echo-planar image acquisition. Regions of interests (ROIs) were generated based on the T1-enhancing tumors irradiated. Relative cerebral blood volume (rCBV) and relative cerebral blood flow (rCBF) parameter maps were calculated by dividing the top 5% of CBV or CBF values within a ROI by the contralateral normal thalamus. LR was determined according to the RECIST 1.1 criteria. Cox regression was conducted to identify factors associated with time to LR. LR rates were estimated with the Kaplan-Meier method and compared using log-rank test. RESULTS: Twenty-three patients were enrolled from 2013 through 2016, with 24 evaluable lesions from 17 patients. After a median follow-up of 12.8 months (range: 3.0–53.7), 5 lesions (21%) developed LR after a median of 3.4 months (range: 2.3–5.7). On univariable analysis, higher rCBV at week 1 (HR 1.06, 95% CI 1.01–1.11, p=0.02), lower SRS dose (HR 0.43, 95% CI 0.20–0.91, p=0.03), and larger tumor volume (HR 1.52, 95% CI 1.05–2.20, p=0.03) were significantly associated with LR, but not histology, rCBV at baseline, change of rCBV at week 1 from baseline, or any rCBF parameters. Higher rCBV at week 1 (above the median) was associated with significantly higher risk of LR than lower rCBV (44% vs 0% at 1 year, respectively, p=0.02). CONCLUSIONS: DSC-PMR and specifically rCBV at week 1 may be a promising imaging biomarker to predict treatment response of brain metastasis after SRS and warrant further investigation.

Objective: Arm exercise stress testing may be an equivalent or better predictor of mortality outcome than pharmacological stress imaging for the ≥50% for patients unable to perform leg exercise. Thus, our objective was to develop an arm exercise ECG stress test scoring system, analogous to the Duke Treadmill Score, for predicting outcome in these individuals. Methods: In this retrospective observational cohort study, arm exercise ECG stress tests were performed in 443 consecutive veterans aged 64.1 (11.1) years. (mean (SD)) between 1997 and 2002. From multivariate Cox models, arm exercise scores were developed for prediction of 5-year and 12-year allcause and cardiovascular mortality and 5-year cardiovascular mortality or myocardial infarction (MI). Results: Arm exercise capacity in resting metabolic equivalents (METs), 1 min heart rate recovery (HRR) and ST segment depression ≥1 mm were the stress test variables independently associated with all-cause and cardiovascular mortality by step-wise Cox analysis (all p

Background The subdermal contraceptive implant and the 52-mg levonorgestrel intrauterine device are currently Food and Drug Administration approved for 3 and 5 years of use, respectively. Limited available data suggested both of these methods are effective beyond that time. Demonstration of prolonged effectiveness will improve the cost-effectiveness of the device, and potentially patient continuation and satisfaction. Objective We sought to evaluate the effectiveness of the contraceptive implant and the 52-mg hormonal intrauterine device in women using the method for 2 years beyond the current Food and Drug Administration–approved duration. Study Design We initiated this ongoing prospective cohort study in January 2012. We are enrolling women using the contraceptive implant or 52-mg levonorgestrel intrauterine device for a minimum of 3 and 5 years, respectively (started intrauterine device in ≥2007 or implant in ≥2009). Demographic and reproductive health histories, as well as objective body mass index, were collected. Implant users were offered periodic venipuncture for analysis of serum etonogestrel levels. The primary outcome, unintended pregnancy rate, was calculated per 100 woman-years. We analyzed baseline demographic characteristics using χ 2 test and Fisher exact test, and compared serum etonogestrel levels stratified by body mass index using the Kruskal-Wallis test. Results Implant users (n = 291) have contributed 444.0 woman-years of follow-up. There have been no documented pregnancies in implant users during the 2 years of postexpiration follow-up. Calculated failure rates in the fourth and fifth years for the implant are calculated as 0 (1-sided 97.5% confidence interval, 0–1.48) per 100 woman-years at 4 years and 0 (1-sided 97.5% confidence interval, 0–2.65) per 100 woman-years at 5 years. Among 496 levonorgestrel intrauterine device users, 696.9 woman-years of follow-up have been completed. Two pregnancies have been reported. The failure rate in the sixth year of use of the levonorgestrel intrauterine device is calculated as 0.25 (95% confidence interval, 0.04–1.42) per 100 woman-years; failure rate during the seventh year is 0.43 (95% confidence interval, 0.08–2.39) per 100 woman-years. Among implant users with serum etonogestrel results, the median etonogestrel level was 207.7 pg/mL (range 63.8-802.6 pg/mL) at the time of method expiration, 166.1 pg/mL (range 67.9 25.0–470.5 pg/mL) at the end of the fourth year, and 153.0 pg/mL (range 72.1-538.8 pg/mL) at the end of the fifth year. Median etonogestrel levels were compared by body mass index at each time point and a statistical difference was noted at the end of 4 years of use with overweight women having the highest serum etonogestrel (195.9; range 25.0-450.5 pg/mL) when compared to normal (178.9; range 87.0-463.7 pg/mL) and obese (137.9; range 66.0-470.5 pg/mL) women ( P = .04). Conclusion This study indicates that the contraceptive implant and 52-mg hormonal intrauterine device continue to be highly effective for at least 2 additional years of use. Serum etonogestrel evaluation demonstrates median levels remain above the ovulation threshold of 90 pg/mL for women in all body mass index classes.
