Context: Outpatient palliative care (PC) has strong evidence demonstrating impact across serious illnesses, resulting in growing demand for skilled outpatient PC clinicians. However, there is limited literature examining the existing state and quality of outpatient PC education during postgraduate training., Objectives: Characterize the current state of outpatient training in United States (US) Hospice and Palliative Medicine (HPM) physician fellowships and elicit perceptions regarding quality of outpatient PC education., Methods: A cross-sectional survey of US adult HPM fellowship program directors (PDs) or their designee conducted between March and July, 2023., Results: Of 161 programs, 85 participated (53% response rate) with representation across all US regions. HPM fellows spend a median of 4.8 weeks in outpatient PC compared to 24 weeks inpatient PC and 10.5 weeks in hospice settings. Over half (51%) of fellows saw outpatients from primarily one disease type with limited exposure to patients with other serious illnesses. Across programs, fellows' clinic structure, interdisciplinary team composition, and didactic experiences varied. On a 5-point rating scale, PDs reported significantly lower quality outpatient versus inpatient training (mean rating: 3.58 vs. 4.62, P<0.001) and perceived fellows as less prepared for independent outpatient practice upon graduation (mean: 4.06 vs. 4.73, P<0.001)., Conclusion: Our survey of US HPM fellowships identified multiple gaps between outpatient and inpatient PC education and training during fellowship and raises concern about the adequacy of outpatient PC training. To prepare the HPM workforce to meet the diverse needs of seriously ill populations and ensure adequate access, outpatient PC training requires reform., (Copyright © 2024 American Academy of Hospice and Palliative Medicine.

Objective: To measure change in financial toxicity from pregnancy to the postpartum period and to identify factors associated with this change., Design: Longitudinal survey., Setting: Obstetric clinics at an academic medical center in Massachusetts between May 2020 and May 2022., Participants: Obstetric patients who were 18 years of age or older (N = 242)., Methods: Respondents completed surveys that included the COmprehensive Score for financial Toxicity tool during pregnancy and in the postpartum period. We collected additional medical record data, including gestational age, birth weight, and cesarean birth. We used paired t tests to assess changes in financial toxicity before and after childbirth and one-way analysis of variance to compare average change in financial toxicity by demographic and medical variables., Results: The mean current financial toxicity score was significantly lower after childbirth (M = 19.0, SD = 4.6) than during pregnancy (M = 21.8, SD = 5.4), t(241) = 13.31, p < .001. Concern for future financial toxicity was not significantly different after childbirth (M = 8.5, SD = 2.9) compared to during pregnancy (M = 8.2, SD = 3.0), t(241) = -1.80, p = .07. Individual-level sociodemographic variables (e.g., racial/ethnic category, insurance, employment) and medical factors (e.g., cesarean birth, preterm birth) were not associated with change in financial toxicity., Conclusion: Among respondents, financial toxicity worsened after childbirth, and patients are at risk regardless of their individual socioeconomic and medical conditions., Competing Interests: Conflict of Interest The authors report no conflicts of interest or relevant financial relationships., (Copyright © 2024 AWHONN, the Association of Women’s Health, Obstetric and Neonatal Nurses.

Research Question: How do perinatal outcomes differ between programmed and modified natural frozen embryo transfer (FET) cycles?, Design: A retrospective cohort study of 839 patients was undertaken at a university-affiliated fertility practice undergoing single blastocyst FET cycles between 2014 and 2020. The primary outcome measures were the incidence of ischaemic placental disease, small for gestational age (SGA), intrauterine growth restriction (IUGR), preterm delivery, birth weight, and mode of delivery., Results: When comparing programmed FET cycles with modified natural FET cycles, there was no increased risk of ischaemic placental disease [adjusted risk ratio (aRR) 0.83, 95% CI 0.61-1.14], IUGR (unadjusted RR 0.50, 95% CI 0.14-1.77), preterm delivery (aRR 1.11, 95% CI 0.72-1.70) or SGA (aRR 0.69, 95% CI 0.40-1.19). Patients in the programmed cohort had increased risk of caesarean delivery (aRR 1.32, 95% CI 1.10-1.59). These outcomes were unchanged when limited to patients undergoing their first FET cycle., Conclusions: There are no differences in patient and neonatal clinical outcomes between programmed and modified natural FET cycles. The choice of FET protocol should remain a shared decision between patient and provider., (Copyright © 2024 Reproductive Healthcare Ltd. Published by Elsevier Ltd. All rights reserved.)

Aims: Cutaneous squamous cell carcinoma in situ (SCCis) can be classified histopathologically into four subtypes: full-thickness (FT), hypertrophic actinic keratosis (HAK), Bowenoid, and acantholytic types. 3%-5% of SCCis lesions progress to invasive squamous cell carcinoma (iSCC), however progression risk by subtype has not been assessed. Aim one of this study is to quantitatively assess the risk of iSCC associated with each histological subtype of SCCis. Aim two is to evaluate if the histological grade of iSCC differs among subtypes of the associated SCCis., Methods: The pathology information system at our institution was queried for cutaneous SCCis cases with and without associated iSCC from 2020 to 2022. The study group consisted of 65 cases of SCCis with associated iSCC and control group 65 randomly selected cases of SCCis without invasion. For each case SCCis subtype was classified as FT, HAK, Bowenoid or acantholytic type. iSCCs were classified as low grade if well to moderately differentiated (LG) and high grade (HG) if moderately to poorly differentiated., Results: iSCC was most often associated with HAK-type SCCis, followed by acantholytic and FT-type SCCis, with Bowenoid type rarely associated with iSCC. 41% (14/34) of iSCCs associated with HAK-type SCCis were HG compared with 84% (21/25) for FT-type SCCis., Conclusions: iSCC is most often associated with HAK-type SCCis, followed by acantholytic and FT-types, and rarely with Bowenoid type. HG invasive SCC is most often associated with FT-type, and LG with HAK-type SCCis. Stratifying SCCis by subtype can inform clinical management., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024. No commercial re-use.

Context: Medical cannabis is increasingly considered for palliation of pain, nausea/vomiting, anorexia, and other symptoms., Objectives: We aimed to determine whether training in hospice and palliative medicine (HPM) adequately prepares fellows to counsel patients about medical cannabis., Methods: A previously validated questionnaire was adapted for HPM fellows. Domains included fellows' practices recommending cannabis and their knowledge of its effectiveness and risks compared with standard treatments. U.S. HPM fellowships were sent surveys in 2022 and 2023., Results: Forty six programs participated, 123 fellows responded (response rate of 42%) including 69% female; 55% White, and 28% Asian. Of respondents, 65% reported receiving formal training regarding medical cannabis; 57% reported discussing medical cannabis with over five patients; 23% recommended medical cannabis to more than five patients in the preceding year. Only 19%, however, felt sufficiently informed to issue cannabis-related recommendations. HPM fellows with prior training were not more likely to feel sufficiently informed to discuss cannabis (RR: 1.17; 95% CI: 0.82-1.66) or to recommend cannabis to patients (RR: 2.05, 95% CI: 0.89-4.71). Fellows rate cannabis as equally or more effective than conventional treatments for the following symptoms: anorexia/cachexia (63%), nausea/vomiting (43%), pain (25%), and neuropathic pain (21%)., Conclusion: Most HPM fellows report formal training in the use of medical cannabis. Over half of trainees reported discussing medical cannabis with patients, but few considered themselves sufficiently informed to make cannabis-related clinical recommendations. These results suggest both a need for expanded high-quality evidence for medical cannabis in palliative care and for improved formal education for HPM fellows., (Copyright © 2024 American Academy of Hospice and Palliative Medicine.

Objectives: To measure plasma concentrations of medroxyprogesterone acetate (MPA) in users with epilepsy treated with antiseizure medications and compare these to MPA concentrations in those without epilepsy., Study Design: For this multisite cross-sectional study, we obtained a single blood sample from those with epilepsy treated with various antiseizure medications (n = 18) within the week before their next depot medroxyprogesterone injection. Among the participants without epilepsy (n = 20), 10 similarly were scheduled within the week prior to the next injection, and 10 were scheduled at earlier intervals to attempt to balance the time intervals between groups. MPA concentrations were determined by a validated assay., Results: MPA concentrations were similar among those with epilepsy and controls and between groups with and without the use of enzyme-inducing medications. The lowest MPA concentrations, under 0.07 ng/mL, were observed among two of eight using enzyme-inducing antiseizure medications, one of 10 using noninducing medications, and one of 19 controls had concentrations below 0.2 ng/mL., Conclusions: In this exploratory study, lower MPA concentrations in some participants using enzyme-inducing antiseizure medications suggest a potential interaction that could reduce depot medroxyprogesterone efficacy., (Copyright © 2024 Elsevier Inc.

Introduction: High-quality health systems rely on care that centers on patient preferences. Realization of patient preferences can improve the birth experience. However, in the dynamic setting of birth, birth preferences can diverge from what is medically indicated. Through studying women and birthing peoples' experiences of unplanned labor procedures, we aimed to identify ways in which practitioners can support women and birthing people through unexpected or unwanted aspects of their delivery. Specifically, we focused on labor induction., Methods: In one large US academic center, women and birthing people participated in prenatal and postpartum surveys regarding their desires, expectations, and experiences of labor induction. From April to November 2021, participants were eligible if they showed discordance between having labor induction and whether it was initially wanted or expected. Interviews focused on attitudes toward birth preferences and outcomes, with attention to discordances. We analyzed interviews through a modified grounded theory approach., Results: Of 22 participants, our sample was predominantly white (91%). Participants in this sample reported discordance between wanting and experiencing (73%) and/or expecting and experiencing (54%) an induction. We identified two themes: "Discordance without mitigation is perceived as a negative experience" and "Practitioner interaction can buffer against negative experience" which includes three ways in which participants prefer support in instances of discordance: preparation, communication, and care and comfort. These methods of support foster patient autonomy and can lead to positive patient experiences., Conclusions: While medical systems should work to support patient preferences, our results suggest that patients can still have positive birth experiences, even when preferences are not fulfilled. Early practitioner preparation, positive communication, and responsive care and comfort may help to improve patient birth experience when challenges arise., (© 2023 Wiley Periodicals LLC.)

Purpose: Little is known about the specific needs during training for hematology/oncology providers practicing in community-based settings. We conducted a national survey of hematologists/oncologists employed in community or academic-community hybrid settings to delineate their educational needs., Methods: An electronic questionnaire was developed and distributed nationally through professional organizations. We primarily assessed whether survey participants received any specific training during fellowship for community-based practice. Participants were also surveyed regarding training experiences that might have affected their preparation. Relative risk (RR) and 95% CI were calculated using modified Poisson regression to identify factors associated with receiving training specifically for community-based settings., Results: Of 125 participants from across 25 states, 63% were male and 58% identified as White. Less than half (41.6%, binomial 95% CI, 32.8 to 50.7) received any training in a community-based setting. Participants identified rotations in community settings (47%), direct mentorship from community-based physicians (40%), and longitudinal clinic in a community setting (36%) as experiences that would have been valuable. Specific curricula of interest included medical operations and administration (63%), health policy (35%), and quality improvement (27%). Respondents in clinical practice for <10 years were more likely to have received any training specifically for a community-based career (RR, 2.13 [95% CI, 1.18 to 3.86])., Conclusion: Our study demonstrates substantial unmet needs as they relate to deliberately training fellows destined for community-based careers. Prospective design of clinical training and curricula emphasizing longitudinal exposures to and key aspects of health care delivery in the community setting are paramount to achieving optimal goal-concordant hematology/oncology training during fellowship.

Background: CD34+ stem cells serve as the primary graft source for allogeneic transplants, with a minimum of 2-4 × 10 6 cells/kg needed for engraftment. There are conflicting data on outcomes at high stem cell doses, with studies limited by few patients receiving doses far above the minimum target., Study Design and Methods: In this retrospective, single-center study of patients with hematologic malignancies who underwent matched unrelated donor transplants, we assessed outcomes for engraftment, survival, relapse, and graft-versus-host disease (GVHD) for the highest CD34+ dose quintile (>13 × 10 6 cells/kg, n = 36) compared to the remaining patients (n = 139). Similar analysis was performed correlating T cell dose and outcomes., Results: There was no difference between the groups in neutrophil engraftment, with a trend toward faster platelet engraftment. There was no significant difference in mortality (adjusted risk ratio [aRR] = 1.02, 95% confidence interval [CI] = 0.85-1.22), relapse (aRR = 1.10, 95% CI = 0.85-1.42), or overall survival by Kaplan-Meier analysis (p = .44). High CD34+ dose was not associated with higher incidence of acute GVHD (aRR = 0.99 grades II-IV, aRR = 1.18 grades III-IV) or chronic GVHD (aRR = 0.87 overall, RR = 1.21 severe). There was limited correlation between CD34+ and T cell dose (R 2  = .073), and there was no significant difference in survival, relapse, or GVHD in the highest T cell dose quintile (n = 33) compared to the remaining quintiles (n = 132)., Discussion: We found no difference in survival, relapse, or GVHD incidence or severity in patients receiving CD34+ doses above prior cutoffs reported in the literature. These data do not support the routine use of graft CD34+ dose reduction., (© 2024 AABB.)

Venous thromboembolism (VTE) is the leading cause of preventable death in hospitalized patients. Artificial intelligence (AI) and machine learning (ML) can support guidelines recommending an individualized approach to risk assessment and prophylaxis. We conducted electronic surveys asking clinician and healthcare informaticians about their perspectives on AI/ML for VTE prevention and management. Of 101 respondents to the informatician survey, most were 40 years or older, male, clinicians and data scientists, and had performed research on AI/ML. Of the 607 US-based respondents to the clinician survey, most were 40 years or younger, female, physicians, and had never used AI to inform clinical practice. Most informaticians agreed that AI/ML can be used to manage VTE (56.0%). Over one-third were concerned that clinicians would not use the technology (38.9%), but the majority of clinicians believed that AI/ML probably or definitely can help with VTE prevention (70.1%). The most common concern in both groups was a perceived lack of transparency (informaticians 54.4%; clinicians 25.4%). These two surveys revealed that key stakeholders are interested in AI/ML for VTE prevention and management, and identified potential barriers to address prior to implementation., (© 2024.

Background: In-hospital consultation is essential for patient care. We previously proposed a framework of seven specific consultation types to classify consult requests to improve communication, workflow, and provider satisfaction., Methods: This multimethods study's aim was to evaluate the applicability of the consult classification framework to real internal medicine (IM) consults. We sought validity evidence using Kane's validity model with focus groups and classifying consult requests from five IM specialties. Participants attended five 1 h semi-structured focus groups that were recorded, transcribed, and coded for thematic saturation. For each specialty, three specialists and three hospitalists categorized 100 (total 500) random anonymized consult requests. The primary outcome was concordance in the classification of consult requests, defined as the sum of partial concordance and perfect concordance, where respectively 4-5/6 and 6/6 participants classified a consult in the same category. We used χ 2 tests to compare concordance rates across specialties and between specialists and hospitalists., Results: Five major themes were identified in the qualitative analysis of the focus groups: (1) consult question, (2) interpersonal interactions, (3) value, (4) miscommunication, (5) consult framework application, barriers, and iterative development. In the quantitative analysis, the overall concordance rate was 88.8% (95% confidence interval [CI]: 85.7-91.4), and perfect concordance was 46.6% (95% CI: 42.2-51.1). Concordance differed significantly between hospitalists and specialists overall (p = .01), with a higher proportion of hospitalists having perfect concordance compared to specialists (67.2% vs. 57.8%, p = .002)., Conclusions: The consult classification framework was found to be applicable to consults from five different IM specialties, and could improve communication and education., (© 2024 Society of Hospital Medicine.)

Introduction: The financial burden of pregnancy in the United States can be high and is associated with worse mental health and birth outcomes. Research on the financial burden of health care, such as the development of the COmprehensive Score for Financial Toxicity (COST) tool, has been conducted primarily among patients with cancer. This study aimed to validate the COST tool and use it to measure financial toxicity and its impacts among obstetric patients., Methods: We used survey and medical record data from obstetric patients at a large medical center in the United States. We validated the COST tool using common factor analysis. We used linear regression to identify risk factors for financial toxicity and to investigate associations between financial toxicity and patient outcomes including satisfaction, access, mental health, and birth outcomes., Results: The COST tool measured two distinct constructs of financial toxicity in this sample: current financial toxicity and concern over future financial toxicity. Racial/ethnic category, insurance, neighborhood deprivation, caregiving, and employment were associated with current financial toxicity (P < 0.05 for all). Only racial/ethnic category and caregiving were associated with concern over future financial toxicity (P < 0.05 for all). Both current and future financial toxicity were associated with worse patient-provider communication, depressive symptoms, and stress (P < 0.05 for all). Financial toxicity was not associated with birth outcomes or keeping obstetric visits., Conclusions: The COST tool captures two constructs among obstetric patients, current and future financial toxicity, both of which are associated with worse mental health and patient-provider communication., (© 2023 Wiley Periodicals LLC.)

Background: Genetically engineered mouse models (GEMMs) of cancer are powerful tools to study mechanisms of disease progression and therapy response, yet little is known about how these models respond to multimodality therapy used in patients. Radiation therapy (RT) is frequently used to treat localized cancers with curative intent, delay progression of oligometastases, and palliate symptoms of metastatic disease., Methods: Here we report the development, testing, and validation of a platform to immobilize and target tumors in mice with stereotactic ablative RT (SART). Xenograft and autochthonous tumor models were treated with hypofractionated ablative doses of radiotherapy., Results: We demonstrate that hypofractionated regimens used in clinical practice can be effectively delivered in mouse models. SART alters tumor stroma and the immune environment, improves survival in GEMMs of primary prostate and colorectal cancer, and synergizes with androgen deprivation in prostate cancer. Complete pathologic responses were achieved in xenograft models, but not in GEMMs., Conclusions: While SART is capable of fully ablating xenografts, it is unable to completely eradicate disease in GEMMs, arguing that resistance to potentially curative therapy can be modeled in GEMMs., (© 2023.

Background: Venous thromboembolism (VTE) is a leading cause of preventable mortality among hospitalized patients, but appropriate risk assessment and thromboprophylaxis remain underutilized or misapplied., Objectives: We conducted an electronic survey of US health care providers to explore attitudes, practices, and barriers related to thromboprophylaxis in adult hospitalized patients and at discharge., Results: A total of 607 US respondents completed the survey: 63.1% reported working in an academic hospital, 70.7% identified as physicians, and hospital medicine was the most frequent specialty (52.1%). The majority of respondents agreed that VTE prophylaxis is important (98.8%; 95% CI: 97.6%-99.5%) and that current measures are safe (92.6%; 95% CI: 90.2%-94.5%) and effective (93.8%; 95% CI: 91.6%-95.6%), but only half (52.0%; 95% CI: 47.9%-56.0%) believed that hospitalized patients at their institution are on appropriate VTE prophylaxis almost all the time. One-third (35.4%) reported using a risk assessment model (RAM) to determine VTE prophylaxis need; 44.9% reported unfamiliarity with RAMs. The most common recommendation for improving rates of appropriate thromboprophylaxis was to leverage technology. A majority of respondents (84.5%) do not reassess a patient's need for VTE prophylaxis at discharge, and a minority educates patients about the risk (16.2%) or symptoms (18.9%) of VTE at discharge., Conclusion: Despite guideline recommendations to use RAMs, the majority of providers in our survey do not use them. A majority of respondents believed that technology could help improve VTE prophylaxis rates. A majority of respondents do not reassess the risk of VTE at discharge or educate patients about this risk of VTE at discharge., (© 2023 The Authors.)

Background: Patients' decision-making and perceptions of outcomes may be impacted by information sources. We investigated use of information by patients and tested the association with patients' perception of treatment outcomes., Methods: We prospectively surveyed patients with advanced solid cancers and their oncologists regarding benefits/risks of non-curative cancer therapies. We previously reported misperception comparing patients' perceptions of treatment outcomes to those of their oncologist. We report external information use as proportions with binomial confidence intervals (CI) and examined correlations with misperception levels using Spearman's correlation coefficient., Results: Of 125 participants, 70% (95% CI: 61-78) stated that they wanted as much information as possible from their oncologist, and nearly all (95%, 95% CI: 90-98) felt the amount of information provided by their clinician was "just right." Over half (60%, 95% CI: 51-69) wanted at least "a moderate amount" of information from sources outside their oncologist, and 58% (95% CI: 49-67) reported obtaining information from sources outside their oncologist. Over two-thirds (69%, 95% CI: 57-79) of participants felt the information from external sources influenced their decisions "a small amount" or less. There was no correlation between information use and misperception regarding tumor response (r: -.04; P = .60) or treatment toxicity (r: .05; P = .60)., Conclusion: Many patients sought information from sources outside their oncologist; few felt it substantially influenced treatment choices. External information use was not associated with greater misperception of treatment outcomes. These data suggest sources of information outside the treating oncologists did not substantially influence patient's decision making.

Purpose: Treatment toxicity from surgery radical prostatectomy (RP) or radiation therapy (RT) has been well studied in patients with localized prostate cancer. However, little is known about lingering toxicities in patients who develop metastatic recurrence. We aimed to compare the prevalence of local treatment-related side effects in patients with metastatic recurrence and those in remission, and to explore to what extent medical oncologists address this morbidity., Methods: This was a single site, cross-sectional study evaluating patient-reported outcomes using the Expanded Prostate Cancer Index Clinical Practice (EPIC-CP) instrument, which measures Health-Related Quality of Life (HRQoL) across urinary, bowel, sexual, and hormonal domains, with higher scores reflecting increased symptom burden. The primary endpoint was differences in overall and domain-specific EPIC-CP scores between the metastatic and localized cohorts, with secondary endpoints evaluating provider interventions for symptom alleviation., Results: Median total EPIC-CP scores were higher in the metastatic cohort (18.0, IQR 13.0-24.0) compared to the localized cohort (10.0, 6.0-15.0) (P < 0.001). This difference was mostly driven by worsening symptoms in the sexual (8.0, 8.0-9.0 vs. 6.0, 3.0-8.0) (P < 0.001) and hormonal domains (2.0, 1.0-6.0 vs. 0.0, 0.0-2.0) (P < 0.001), although there were also differences in the urinary irritation/obstruction (3.0, 0.0-3.0 vs. 1.0, 0.0-2.0) (P < 0.001) and bowel domains (1.0, 0.0-3.0 vs. 0.0, 0.0-0.0) (P < 0.001). There was a trend towards higher scores in patients that had received RT as primary treatment. Medical oncologists rarely changed management in response to local symptoms., Conclusion: Prostate cancer patients with metastatic recurrence suffer from a higher burden of localized treatment-related symptoms compared with patients in remission, with primary RT associated with more prevalent toxicity than radical prostatectomy. There is an unmet need for more intensive management of local symptoms. Further studies should focus on factors that portend long term worse morbidity., Competing Interests: Conflict of Interest DS: none. LED: none. PC: none.

Background: The copper intrauterine device (Cu-IUD) is a highly effective method of contraception that can also be used for emergency contraception (EC). It is the most effective form of EC, and is more effective than other existing oral regimens also used for EC. The Cu-IUD provides the unique benefit of providing ongoing contraception after it is inserted for EC; however, uptake of this intervention has been limited. Progestin IUDs are a popular method of long-acting, reversible contraception. If these devices were also found to be effective for EC, they would provide a critical additional option for women. These IUDs could not only provide EC and ongoing contraception, but additional non-contraceptive benefits, including a reduction in menstrual bleeding, cancer prevention, and pain management., Objectives: To examine the safety and effectiveness of progestin-containing IUDs for emergency contraception, compared with copper-containing IUDs, or compared with dedicated oral hormonal methods., Search Methods: We considered all randomized controlled trials and non-randomized studies of interventions that compared outcomes for individuals seeking a levonorgestrel IUD (LNG-IUD) for EC to a Cu-IUD or dedicated oral EC method. We considered full-text studies, conference abstracts, and unpublished data. We considered studies irrespective of their publication status and language of publication., Selection Criteria: We included studies comparing progestin IUDs with copper-containing IUDs, or oral EC methods for emergency contraception., Data Collection and Analysis: We systematically searched nine medical databases, two trials registries, and one gray literature site. We downloaded all titles and abstracts retrieved by electronic searching to a reference management database, and removed duplicates. Three review authors independently screened titles, abstracts, and full-text reports to determine studies eligible for inclusion. We followed standard Cochrane methodology to assess risk of bias, and analyze and interpret the data. We used GRADE methodology to assess the certainty of the evidence., Main Results: We included only one relevant study (711 women); a randomized, controlled, non-inferiority trial comparing LNG-IUDs to Cu-IUDs for EC, with a one-month follow-up. With one study, the evidence was very uncertain for the difference in pregnancy rates, failed insertion rates, expulsion rates, removal rates and the difference in the acceptability of the IUDs. There was also uncertain evidence suggesting the Cu-IUD may slightly increase rates of cramping and the LNG-IUD may slightly increase bleeding and spotting days.  AUTHORS' CONCLUSIONS: This review is limited in its ability to provide definitive evidence regarding the LNG-IUD's equivalence, superiority, or inferiority to the Cu-IUD for EC. Only one study was identified in the review, which had possible risks of bias related to randomization and rare outcomes. Additional studies are needed to provide definitive evidence related to the effectiveness of the LNG-IUD for EC., (Copyright © 2023 The Cochrane Collaboration. Published by John Wiley & Sons, Ltd.)

Background: Early integration of palliative care (PC) improves outcomes for patients with cancer and heart failure. Data on the role of PC in complex general medicine patients is scant., Measures: We identified high-mortality risk patients from our primary care practice by screening with mortality indices upon hospital admission. We measured documentation of advanced care planning (ACP), including health care proxy (HCP) and goals of care (GOC), at admission and discharge., Intervention: We offered pro-active PC consultation to attending physicians of patients with high mortality risk. Patients who received pro-PC consultation were compared to patients whose attending physicians declined consultation (pro-PC declined) as well as patients who received usual care (UC)., Outcomes: Compared to UC and pro-PC declined groups, the pro-active PC group demonstrated increased rates of HCP and GOC documentation., Conclusions: Our initiative identified hospitalized primary care patients with high-mortality risk, improved gaps in ACP, and was feasible to implement., (Copyright © 2022 American Academy of Hospice and Palliative Medicine.

Objective: Prior work shows that ads related to abortion services often feature crisis pregnancy centers instead of abortion providers. We investigated whether a change in Google's advertising policy that required advertisers to disclose whether they provided abortion services increased the proportion of ads facilitating abortion self-referral., Study Design: We used a standardized protocol to search online for abortion services before, during, and after the policy change; we performed searches in August 2016 to June 2017, June 2019, and October 2019, respectively, using Google, Bing, and Yahoo search engines. We performed searches for the 25 most populous U.S. cities and the 43 state capitals not already included. We classified up to the first 5 ads as facilitating abortion referral, hindering abortion referral, or providing neutral content. We compared search engine results using a chi-square test., Results: Among ads returned by Google, those shown after the policy change were significantly more likely to facilitate abortion self-referral (66.7% vs. 44.2%; p = 0.003) and slightly less likely to hinder abortion self-referral (33.3% vs. 40.6%; p = 0.33) compared to before the change. These findings were reversed for ads shown by Bing and Yahoo; ads returned after the change were significantly less likely to facilitate abortion self-referral (24.6% vs. 32.8%; p = 0.01) and significantly more likely to hinder self-referral (28.3% vs. 21.6%; p = 0.03) compared to before the change., Conclusion: A policy requiring advertisers to disclose whether they provide abortion services was associated with increasing the proportion of ads facilitating self-referral. Similar policies should be considered by all search engines., Implications: While the internet is a convenient source of information that individuals often use to locate abortion providers, the information may not actually lead searchers to services. Search engines should consider restricting abortion-related advertising to organizations that provide abortion services in order to ensure that individuals searching online for abortion services are able to locate services in a direct and timely manner., (Copyright © 2022.

Context: While fluoride has been added to drinking water and dental products for decades in order to prevent tooth decay, there are growing concerns about its potential toxicity. Given that fluoride is primarily excreted in urine, an important question that has not been examined is whether among those whose drinking water is fluoridated, impaired renal function is associated with higher levels of circulating fluoride., Objective: To examine the association between drinking water and plasma fluoride and its modification by renal function., Design, Setting, and Participants: Participants in the National Health and Nutrition Examination Survey (NHANES) between 2013 and 2016 with measures of fluoride in plasma and drinking water and renal function. These measures were only available in adolescent age 12-19 years., Outcomes: Plasma fluoride levels and their modification by strata of renal function, measured by the estimated glomerular filtration rate (eGFR)., Results: Among 1841 healthy adolescents, a 10 ml/min/1.73 m (Penman et al., 1997) lower eGFR and a 1 mg/L higher drinking water fluoride concentration were associated with a 0.02 (95%CI -0.02, -0.03) umol/L and 0.23 (95%CI 0.15,0.30) umol/L higher adjusted plasma fluoride level, respectively. The association of water and plasma fluoride levels was most robust among those with lower renal function (multiplicative interaction p value < 0.001). For adolescents in the lowest eGFR quartile, a 1 mg/L higher drinking water fluoride concentration was associated with a 0.35 (95%CI 0.21,0.48) umol/L higher plasma fluoride level, compared to 0.20 (95%CI 0.14,0.26) umol/L in the highest eGFR quartile. Restriction to those with measurable plasma fluoride levels yielded similar results., Conclusions: Water fluoridation results in higher plasma fluoride levels in those with lower renal function. How routine water fluoridation may affect the many millions of Americans with Chronic Kidney Disease, who are particularly susceptible to heavy metal and mineral accumulation, needs to be further investigated., (Copyright © 2022 Elsevier Inc.

Research Question: Can an empathic physician phone call in the interval between embryo transfer and first serum human chorionic gonadotrophin measurement decrease anxiety and distress amongst patients undergoing IVF?, Design: This was a randomized controlled trial at a single academically-affiliated fertility centre including patients aged 18-43 undergoing their first embryo transfer with autologous fresh or euploid cryopreserved embryos following preimplantation genetic testing for aneuploidies (frozen embryo transfer, FET/PGT-A). After embryo transfer, participants were randomized to a 5-minute scripted phone call (intervention) from a single physician 3-4 days after embryo transfer or to routine care. The primary and secondary outcomes included were change in State-Trait Anxiety Inventory (STAI) and Hospital Anxiety and Depression Scale (HADS) scores from the start of IVF stimulation to 8-9 days after embryo transfer, respectively., Results: A total of 231 participants (164 fresh, 67 FET/PGT-A) were randomized to intervention (n = 116) or routine care (n = 115). While mean STAI and HADS scores increased in both groups, the intervention group experienced lower mean increases than the routine care group for both the STAI (3.3 [0.97] versus 7.8 [1.10], respectively; P = 0.002) and the HADS (0.3 [0.44] versus 2.4 [0.53], respectively; P = 0.003). Most participants in the intervention group found the call helpful (91.4%) and reported that it decreased distress and anxiety (81%)., Conclusions: A brief empathic phone call from a physician during the waiting period resulted in significantly lower self-reported levels of patient anxiety and distress. As the intervention in this study averaged 5 min, implementing this in clinical practice would not be onerous and may ease the distress associated with the waiting period., (Copyright © 2022.

Objectives: To evaluate whether an initial or two-day percent increase in serum beta-human chorionic gonadotropin (βhCG) is associated with ischemic placental disease (IPD) in singleton pregnancies after autologous or donor IVF., Study Design: This was a secondary analysis of a retrospective cohort study of deliveries linked to IVF cycles at a single academic tertiary hospital and infertility treatment center. We included all patients (≥18 years old) who had a singleton live birth or intrauterine fetal demise (IUFD) resulting from either autologous fresh (n=1,347), autologous frozen (n=454), or donor (n=253) IVF cycles. Main outcome reassures: The primary outcome was a composite outcome of IPD or IUFD due to placental insufficiency. IPDs included preeclampsia, placental abruption, and small for gestational age (SGA)., Results: Neither initial βhCG nor two-day percent increases in βhCG were associated with an increased risk of IPD for any type of IVF cycle. Initial and two-day percent increases in βhCG were significantly higher when comparing frozen with fresh IVF and donor with autologous IVF (all P≤0.01)., Conclusions: Among singleton autologous and donor IVF cycles, the initial and two-day percent increase in serum βhCG were not associated with IPD or its components. However, significant βhCG differences existed by cycle type and oocyte source., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2022, Shah et al.)

Study Question: Is there a relationship between endometrial compaction and live birth in euploid frozen embryo transfer (FET) cycles?, Summary Answer: Live birth rates (LBRs) were similar in both patients that demonstrated endometrial compaction or no compaction in single euploid FETs., What Is Known Already: There has been increasing interest in the correlation between endometrial compaction and clinical outcomes but there has been conflicting evidence from prior investigations., Study Design, Size, Duration: This was a prospective observational study from 1 September 2020 to 9 April 2021., Participants/materials, Setting, Methods: This study was performed at a single, academically affiliated fertility center in which patients who had an autologous single euploid FET using a programmed or modified natural cycle protocol were included. All embryos had trophectoderm biopsy for preimplantation genetic testing for aneuploidy followed by vitrification at the blastocyst stage. Two ultrasound measurements of endometrial thickness (EMT) were obtained. The first measurement (T1) was measured transvaginally within 1 day of initiation of progesterone or ovulation trigger injection, and a second EMT (T2) was measured transabdominally at the time of embryo transfer (ET). The primary outcome (LBR) was based on the presence and proportion of compaction (percentage difference in EMT between T1 and T2)., Main Results and the Role of Chance: Of the 186 participants included, 54%, 45%, 35%, 28% and 21% of women exhibited >0%, ≥5%, ≥10%, ≥15% and ≥20% endometrial compaction, respectively. Endometrial compaction was not predictive of live birth at any of the defined cutoffs. A sub-analysis stratified by FET protocol type (n = 89 programmed; n = 97 modified natural) showed similar results., Limitations, Reasons for Caution: There was the potential for measurement error in the recorded EMTs. The T2 measurement was performed transabdominally, which may cause potential measurement error, as it is generally accepted that transvaginal measurements of EMT are more accurate, though, any bias is expected to be non-differential. The sub-analysis performed looking at FET protocol type was underpowered and should be interpreted with caution. Our study, however, represents a pragmatic approach, as it allowed patients to avoid having to come in for an extra transvaginal ultrasound the day before or on the day of ET., Wider Implications of the Findings: Assessing endometrial compaction may lead to unnecessary cycle cancellation. However, further studies are needed to determine if routine screening for endometrial compaction would improve clinical outcomes., Study Funding/competing Interest(s): No authors report conflicts of interest or disclosures.

Background: The consequences of low levels of environmental heavy metal exposure, as found widely in the United States, in those with impaired renal function remain underexplored., Methods: We examined the cross-sectional association of indices of renal function with lead and cadmium levels in blood and urine among National Health and Nutrition Examination Survey (NHANES) participants. We used the 1999-2002 cycle, which included measures of cystatin C, in order to quantify renal function most precisely and defined chronic kidney disease (CKD) as an estimated glomerular filtration rate (eGFR) <60 ml/min per 1.73 m 2 ., Results: In weighted and adjusted analyses of 5638 participants, lead levels were 0.23 (95% CI, 0.03 to 0.42) μ g/dl higher among participants with CKD, and 0.05 (95% CI, 0.01 to 0.09) μ g/dL higher per 10 ml/min per 1.73 m 2 lower eGFR. Cadmium levels were 0.02 (95% CI, 0.01 to 0.03) μ g/L higher per 10 ml/min per 1.73 m 2 lower eGFR. Black race significantly modified the association of lower eGFR with higher circulating lead levels ( P interaction <0.001). A 10 ml/min per 1.73 m 2 lower eGFR was associated with a 0.13 (95% CI, 0.06 to 0.21) μ g/dl higher lead level among Black participants compared with 0.03 (95% CI, -0.04 to 0.11) μ g/dl higher level among White participants. Among the 1852 participants with urinary metal measurements, despite higher circulating levels, those with CKD had significantly lower urinary lead levels (-0.16 [95% CI, -0.30 to -0.01] ng/ml) and urinary lead/creatinine ratios (-0.003 [95% CI, -0.004 to -0.001])., Conclusions: CKD is associated with higher blood lead levels, particularly among Blacks, and simultaneously, lower urinary lead levels, consistent with the hypothesis that CKD confers a state of heighted susceptibility to heavy metal environmental exposure by reducing its elimination. Given that low levels of exposure remain highly prevalent in the United States, further efforts to protect patients with CKD from heavy metal toxicity may be warranted., Competing Interests: J.

Purpose: Palliative care (PC) improves outcomes in advanced cancer, and guidelines recommend early outpatient referral. However, many PC teams see more inpatient than outpatient consults. We conducted a retrospective study of hospitalized patients with cancer to quantify exposure to inpatient and outpatient PC and describe associations between PC and end-of-life (EOL) quality measures., Methods: We identified all decedents admitted to an inpatient oncology unit in 1 year (October 1, 2017-September 30, 2018) and abstracted hospitalization statistics, inpatient and outpatient PC visits, and EOL outcomes. Descriptive statistics, univariate tests, and multivariate analysis evaluated associations between PC and patient outcomes., Results: In total, 522 decedents were identified. 50% saw PC; only 21% had an outpatient PC visit. Decedents seen by PC were more likely to enroll in hospice (78% v 44%; P < .001), have do-not-resuscitate status (87% v 55%; P < .001), have advance care planning documents (53% v 31%; P < .001), and die at home or inpatient hospice instead of in hospital (67% v 40%; P < .01). Decedents seen by PC had longer hospital length-of-stay (LOS; 8.4 v 7.0 days; P = .03), but this association reversed for decedents seen by outpatient PC (6.3 v 8.3 days; P < .001), who also had longer hospice LOS (46.5 v 27.1 days; P < .01) and less EOL intensive care (6% v 15%; P < .05)., Conclusion: PC was associated with significantly more hospice utilization and advance care planning. Patients seen specifically by outpatient PC had shorter hospital LOS and longer hospice LOS. These findings suggest different effects of inpatient and outpatient PC, underscoring the importance of robust outpatient PC., Competing Interests: Jonathan C.

Background: Advance care planning (ACP) is important to improving end-of-life care. Few studies have examined the impact of primary care physician (PCP) involvement in ACP. Objectives: To determine whether complete ACP, defined as health care proxy (HCP), provider orders for life-sustaining treatment (POLST), and documented goals-of-care (GOC) conversations, would occur earlier when the PCP was involved in POLST and/or GOC conversations. Design: Charts of deceased patients from 2015 to 2017 in a U.S. academic primary care practice were reviewed. Demographic factors, mortality risk scores, palliative care involvement, and visits within the last year of life to PCPs and specialists were collected. Poisson models with robust variance estimators were used to estimate the likelihood of PCP involvement being associated with earlier complete ACP after adjusting for confounders and accounting for clustering by PCP. Due to high rates of HCP documentation at the institution, 10 patients without HCP were excluded from the review. Results: Of 403 decreased patients, 71 (18%) met criteria for complete ACP and 214 (53%) had HCP only; the remaining 118 patients had partial (2/3 components) ACP. Of the 71 patients with complete ACP, 40.1% had ACP earlier than three months of death (early) and 59.2% had ACP within three months of death (late). PCP involvement was associated with early ACP compared with late ACP and HCP only for both PCP completion of the POLST (risk ratio [RR]: 4.7; 95% confidence interval [CI]: 1.3-17.1) and for PCP documentation of GOC conversation (RR: 4.6; 95% CI: 1.2-17.1) after adjustment for clustering by PCP and other relevant variables. Conclusion: This retrospective cohort study suggests that PCP involvement in ACP correlates with earlier completion. This finding highlights the importance of educating and encouraging PCPs on completing ACP with their patients.

Objective: The objective of this study was to examine the predictive value of fibrinogen concentration for bleeding complications among women presenting for delivery and for whom a fibrinogen level was measured before delivery., Study Design: This was a nested case-control study using a cohort of all women who delivered at our institution from October 2001 to July 2016 and in whom a fibrinogen concentration was obtained within 48 hours before delivery. We identified all cases that had one or more of the following events: (1) postpartum hemorrhage; (2) postpartum hysterectomy; (3) transfusion of select blood products; or (4) a ≥ 33% decrease in hematocrit from the first hematocrit measured during the hospital stay to any subsequent hematocrit value drawn either simultaneously with or following the fibrinogen concentration measurement. We included the first case or control delivery for a given woman. Controls were the next one or two consecutive deliveries without a bleeding complication and matched for number of fetuses. We used logistic regression to calculate the odds ratio and 95% confidence intervals and calculated the area under the receiver operating characteristic curve., Results: We identified 424 cases and 801 controls. The mean predelivery fibrinogen concentration was significantly lower in cases (425 ± 170 mg/dL) than controls (523 ± 122 ng/mL) for all case types combined ( p  < .001) and for each case type individually (all p  < .001). For every 100-mg/dL decrease in fibrinogen, the odds of a bleeding complication increased 1.63 times (95% confidence interval: 1.48-1.80). However, the area under the receiver operating characteristic curve was poor (0.69; 95% confidence interval: 0.65-0.72). Below 300 mg/dL there were 104 (24.5%) cases and 31 (3.9%) controls, yielding high specificity (96.1%) but extremely low sensitivity (24.5%). We could not identify a cutoff value that yielded acceptable values of both sensitivity and specificity., Conclusions: Antepartum fibrinogen concentration was significantly lower among women who developed bleeding complications, though these differences may not be large enough to provide clinically meaningful critical values. Nevertheless, a higher threshold for the critical value during pregnancy should be considered.

Background: We previously reported an association between team training in the ambulatory setting and improvements in team climate at 6 and 12 months, but it is unknown whether improvements persist at 2 years., Study Design: From 2014 to 2015, we enrolled 20 organizations, each operating a varying number of health centers, into a teamwork training initiative. We evaluated teamwork outcomes at baseline and 2 years using a communication behaviors assessment, the TeamSTEPPS ® Teamwork Perceptions Questionnaire (T-TPQ), and the Patients' Insights and Views of Teamwork (PIVOT) survey., Results: At 2 years, use of TeamSTEPPS ® tools and strategies remained increased compared to baseline at many health centers; results ranged from 32% of centers reporting increased use of pauses to identify the patient to 91% reporting increased use of standardized language. Staff T-TPQ responses indicated that TeamSTEPPS ® implementation was associated with improved perceptions of teamwork in approximately half (49%) of statements at 2 years. Significant improvements occurred in over half of PIVOT survey statements, and patient satisfaction was significantly greater at 2 years compared to baseline., Conclusions: Patient and staff views of teamwork were significantly improved 2 years after TeamSTEPPS ® implementation in ambulatory reproductive health care centers, demonstrating positive long-term effects of teamwork training., (© 2020 American Society for Healthcare Risk Management of the American Hospital Association.)

Objectives: We aimed to identify and characterize barriers faced by researchers studying abortion in academic medical centers in the United States. We specifically focused on regulatory restrictions on abortion research related to institutional review board (IRB) or research ethics committee interpretations of Subpart B of the 2001 Code of Federal Regulations, which states that researchers cannot take part in decisions involving the timing, method, or procedures used to terminate a pregnancy. We aimed to document investigators' experiences obtaining approval from their IRBs and to identify obstacles that prevent investigators from generating evidence related to abortion care., Study Design: We conducted semistructured telephone interviews with family planning researchers at 15 US academic institutions across the country. We coded transcripts using an iterative process, and analyzed the data for content and themes., Results: Interviewees reported significant variations in the way that IRBs at their institutions applied federal regulations to abortion research. At several institutions, the regulations represented barriers to conducting abortion research and discouraged some investigators from conducting such research altogether. At other institutions, interviewees did not face significant barriers related to their IRB's interpretation of Subpart B. Many interviewees discussed creating and maintaining positive professional relationships with members of their IRB as a way to overcome barriers and successfully conduct abortion research., Conclusions: Our study suggests that IRBs interpret Subpart B in varying ways. At some institutions, this creates barriers to conducting abortion research. However, abortion researchers have also found ways to navigate these challenges successfully., Implications: This exploratory study identified barriers that may constrain the generation of evidence in abortion care at some academic institutions, and can inform future endeavors to overcome limitations to abortion research., (Copyright © 2021 Elsevier Inc.

Objective: Headache is the presenting symptom of unruptured intracranial aneurysm (UIA) in more than one-third of cases. Some patients may expect their headache to remit after aneurysm treatment. This study aims to identify factors influencing headache outcomes following endovascular treatment of UIA., Methods: This prospective observational study was conducted in patients with UIAs treated with flow diversion. Subjects reported their headache intensity with a visual analog scale (VAS) and completed 3 surveys before treatment: Migraine Disability Assessment (MIDAS), Headache Impact Test (HIT-6), and Patient Health Questionnaire-2 (PHQ-2). Follow-up was at 1 month, 3 months, and 6 months after treatment. Analysis was performed using generalized mixed-effects models., Results: We identified 38 patients, 29 of whom reported headaches at baseline (76.3%). Mean patient age was 55.3 ± 12.4 years, and 79% of the cohort was female. Mean aneurysm diameter was 6.8 ± 5.3 mm, and treatment modality was Pipeline embolization in all cases. At the last follow-up, 5 aneurysms (15.1%) were incompletely occluded. The mean VAS scores for patients with headache at baseline were 4.36 ± 0.59 at baseline, 4.08 ± 0.60 at 1 month, 3.04 ± 0.62 at 3 months, and 2.76 ± 0.57 at 6 months. Controlling for occlusion status, medication, and depression, significant improvement was seen at the 3- and 6-month follow-ups. Similar patterns were observed with MIDAS and HIT-6., Conclusions: In the present study, endovascular UIA treatment led to significantly decreased headache intensity in patients with headache at baseline, after a short delay. Our data shed light on postintervention headache patterns and can help inform patient discussions and treatment expectations., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Analyzing data on ART presents unique and sometimes complicated challenges related to choosing the unit(s) of analysis and the statistical model. In this commentary, we provide examples of how these challenges arise and guidance for overcoming them. We discuss the implications of different ways to count treatment cycles, considering the perspectives of research questions, data management and analysis and patient counseling. We present the advantages and disadvantages of different statistical models, and finally, we discuss the definition and calculation of the cumulative incidence of live birth, which is a key outcome of research on ART., (© The Author(s) 2020.

A mediator is a factor that occurs after the exposure of interest, precedes the outcome of interest (i.e. between the exposure and the outcome) and is associated with both the exposure and the outcome of interest (i.e. is on the pathway between exposure and outcome). Mediation analyses can be valuable in many reproductive health contexts, as mediation analysis can help researchers to better identify, quantify and understand the underlying pathways of the association they are studying. The purpose of this commentary is to introduce the concept of mediation and provide examples that solidify understanding of mediation for valid discovery and interpretation in the field of reproductive medicine., (© The Author(s) 2020.

The majority of research within reproductive and gynecologic health, or investigating ART, is observational in design. One of the most critical challenges for observational studies is confounding, while one of the most important for discovery and inference is effect modification. In this commentary, we explain what confounding and effect modification are and why they matter. We present examples illustrating how failing to adjust for a confounder leads to invalid conclusions, as well as examples where adjusting for a factor that is not a confounder also leads to invalid or imprecise conclusions. Careful consideration of which factors may act as confounders or modifiers of the association of interest is critical to conducting sound research, particularly with complex observational studies in reproductive medicine., (© The Author(s) 2020.

Objective: To identify factors associated with financial performance of independently owned companion and mixed animal veterinary practices., Sample: Financial statements (ie, annual balance sheets and income statements for 3 consecutive years) were obtained from 45 practices., Procedures: Ratio analysis of financial statements was performed with the DuPont Model, and practices were grouped into 4 financial performance groups on the basis of return on equity. Liquidity and solvency ratios and debt management and asset investment practices were then compared among financial performance groups., Results: Financial liquidity was low across all financial performance groups, but most practices were solvent, with assets exceeding liabilities. Debt management was found to be a limiting factor for financial success, with lower-performing practices using credit cards and lines of credit to purchase capital assets. Practices that were not solvent owed debts on the purchase of intangible assets and had higher owner withdrawals, compared with other practices. Practices that built productive capacity by borrowing and investing in productive assets had higher long-term returns., Conclusions and Clinical Relevance: Results suggested that proper debt management coupled with prudent asset investment was associated with higher financial performance for independently owned companion and mixed animal veterinary practices.

Objective: To determine whether younger oocyte donor age is associated with better outcomes after in vitro fertilization (IVF) compared with older oocyte donor age., Design: A retrospective cohort study., Setting: Large academically affiliated infertility treatment center., Patients: We included all women ≥ 18 years who started their first fresh cycle using donor oocytes at our center from January 2002 through October 2017; only the first oocyte recipient cycle was analyzed., Intervention: Log-binomial regression was used to compare the incidence of clinical pregnancy and live birth among the following donor age groups: < 25 years, 25 to < 30 years, and 30 to <35 years., Main Outcome Measure: Incidence of clinical pregnancy and live birth among donor age groups., Results: We included 774 donor cycles; 269 (34.8%) used donors < 25 years, 399 (51.6%) used donors 25 to < 30 years, and 106 (13.7%) used donors 30 to < 35 years. Median donor age was 26 years (range 18-34.5), and median recipient age and partner age were both 42 years. Per cycle start, after adjusting for recipient age, cycles using donors < 25 years were not associated with a higher incidence of clinical pregnancy (RR 0.90; 95% CI 0.77-1.06) or live birth (RR 0.87; 95% CI 0.72-1.04) compared with donors age 25-< 30 years., Conclusions: Donor age < 25 was not associated with better outcomes after IVF. Under the age of 30, the prioritization of <25 year old donors may not be recommended given the lack of evidence for superior pregnancy or live birth outcomes.

Background: While team training is associated with improved hospital-based team climate, less is known about effects in the ambulatory setting., Study Design: In 2014 and 2015, we enrolled 20 organizations, each operating various health centers, into this ongoing study. Evaluation tools include a communication behaviors assessment (CBA) and Team Strategies and Tools to Enhance Performance and Patient Safety (TeamSTEPPS ® ) Teamwork Perceptions Questionnaire (T-TPQ), which staff completes at baseline, 6 months, and 1 year, and the Patients' Insights and Views of Teamwork (PIVOT) survey, which patients complete at baseline and 1 year. We also assessed patient satisfaction. We analyzed T-TPQs paired at the individual level and CBAs and PIVOTs paired at the health center level. We also conducted key informant interviews with the first cohort., Results: CBAs showed that TeamSTEPPS tools and strategies were utilized, with 50% or more of centers reporting increases in all behaviors at 1 year; key informant interviews confirmed this. T-TPQ findings indicated that TeamSTEPPS implementation was associated with improved staff perceptions of teamwork at 6 months; lesser improvements were seen at 1 year. The PIVOT survey demonstrated significant improvements in select patient ratings of teamwork. Patient satisfaction improved at 1 year., Conclusions: TeamSTEPPS has positive effects in the ambulatory reproductive health care environment. Improvements persisted at 1 year., (© 2018 American Society for Health Care Risk Management of the American Hospital Association.)

Objective: To compare the incidence of group B Streptococcus (GBS) conversion from a negative antepartum to a positive intrapartum culture among women who self-identify as non-Hispanic black, Hispanic, or non-Hispanic white., Study Design: This was a prospective cohort study of women with a negative rectovaginal GBS culture obtained within 35 days of enrollment. An intrapartum rectovaginal swab was collected and cultured for GBS. Data were compared with chi-square, Fisher's exact, or Wilcoxon rank-sum test. Modified Poisson regression was used., Results: We enrolled 737 women; 75.4% were non-Hispanic white, 17.6% were non-Hispanic black, and 6.9% were Hispanic. Non-Hispanic black women were more likely to convert to GBS positive than non-Hispanic white women, 9.2% as compared to 5.3% (RR: 2.0; 95% CI: 1.02-3.8)., Conclusion: The increased incidence of positive intrapartum GBS cultures among non-Hispanic black women suggests that non-Hispanic black race is a risk factor for GBS conversion in the late third trimester.

Our objective was to determine if a correlation exists between endometrial thickness measured on the day of ovulation trigger during an in vitro fertilization (IVF) cycle and pregnancy outcomes among non-cancelled cycles. We performed a retrospective cohort study looking at 6331 women undergoing their first, fresh autologous IVF cycle from 1 May 2004 to 31 December 2012 at Boston IVF (Waltham, MA). Our primary outcome was the risk ratio (RR) of live birth and positive β-hCG. We found that thicker endometrial linings were associated with positive β-hCG and live birth rates. For each additional millimetre of endometrial thickness, we found a statistically significant increased risk of positive β-hCG (adjusted RR: 1.14; 95% CI: 1.09-1.18) and live birth (RR: 1.08; 95% CI: 1.05-1.11). There was no association between endometrial thickness and miscarriage (RR: 0.99; 95% CI: 0.91-1.07). Similar results were seen when categorizing endometrial thickness. Compared with an endometrial thickness >7 to <11 mm, the likelihood of a live birth was significantly higher for an endometrial thickness ≥11 mm (adjusted RR: 1.23; 95% CI: 1.11-1.37) and significantly lower for the ≤7 mm group (adjusted RR: 0.64; 95% CI: 0.45-0.90). In conclusion, thicker endometrial linings were associated with increased pregnancy and live birth rates.

Objective: To assess the quality of information available online for abortion self-referral and to determine whether quality varies by region or distance to an abortion provider., Methods: This was a cross-sectional study. We used a standard protocol to perform internet searches from August 2016 to June 2017 for abortion services in the 25 most populous U.S. cities and the 43 state capitals that were not one of the 25 most populous cities. We classified the first 10 webpage results and the first five map results and advertisements as facilitating abortion referral (local independent abortion provider, local Planned Parenthood facility, national abortion provider or organization, prochoice website, or abortion directory), not facilitating abortion referral (nonproviding physician office, nonmedical website, abortion provider greater than 50 miles from the location, news article, general directory, other), or hindering abortion referral (crisis pregnancy center or antichoice website). We used U.S. Census Bureau subregions to examine geographic differences. We made comparisons using a χ test., Results: Overall, from 612 searches from 68 cities, 52.9% of webpage results, 67.3% of map results, and 34.4% of advertisements facilitated abortion referral, whereas 12.9%, 21.7%, and 29.9%, respectively, hindered abortion referral. The content of the searches differed significantly based on U.S. Census Bureau subregion (all P≤.001) and distance to an abortion provider (all P≤.02)., Conclusion: Two thirds of map results facilitated abortion self-referral, whereas only half of webpage results did so. Advertisements were the least likely to facilitate and the most likely to hinder self-referral. Quality was lowest in areas that were farthest from abortion providers.
