Calculating surgical readmission rates in gynecologic oncology: The impact of patient factors.

OBJECTIVE: To determine the 30-day surgical readmission rate after major gynecologic oncology surgeries at a high-volume academic institution and correlated risk factors. METHODS: Retrospective cohort study was conducted of surgical admissions from January 2016 - December 2019 at a single institution. Data were extracted from patient charts, including reason for readmission and length of stay. A readmission rate was calculated. Nested case control design was used to identify correlations between readmission and patient specific risk-factors. Multivariable logistic regression models were used to determine risk factors with readmission. RESULTS: A total of 2152 patients were included. The readmission rate was 3.5%, most commonly due to GI disturbance and surgical site infection. Average readmission length was 5 days. Prior to adjusting for covariates, insurance status, primary diagnosis, index admission length, and disposition at discharge differed between patients who were and were not readmitted. After adjusting for co-variates, younger patients, index admission >2 days, and higher Charlson co-morbidity index were associated with readmission. CONCLUSIONS: Our surgical readmission rate was lower than previously reported rates in gynecologic oncology patients. Patient factors associated with readmission included younger age, longer index hospital admission, and higher medical co-morbidity index scores. Provider factors and institutional practice patterns could contribute to the decreased readmission rate. These findings underscore the importance of standardizing how we calculate readmission rate and interpret these data. Varying readmission rates and institutional practice patterns deserve closer scrutiny to inform best practice and future policies.

Results of Immediate Postpartum Long Acting Reversible Contraception Provision After Expanded Reimbursement Policy Implementation at an Academic Medical Institution.

INTRODUCTION: Immediate postpartum (IPP) Long Acting Reversible Contraception (LARC) is effective in reducing short birth spacing, which is highest among minoritized and younger women with lower socioeconomic status. The structural barrier of cost for pregnant people who desire IPP LARC insertion was alleviated in 2016 when New York State provided statewide reimbursement for Medicaid recipients. METHODS: Analyses of existing electronic medical records (EMR) were conducted on women who received IPP LARC between 3/2/17 and 9/2/19 at two hospitals after a term delivery, defined as gestational age 37 0/7 weeks or greater. Descriptive and bivariate statistics, including chi-square tests and Fischer's exact tests, based on cell sizes, were calculated using SAS (version9.4). RESULTS: Prior to the study period, IPP LARC was not placed in these hospitals. After reimbursement policy changes, electronic medical record data identified 501 women with full term delivery and IPP LARC placed, of which the majority were single (82.8%), Black (49.1%), and had public insurance (Medicaid and Medicaid Managed Care) (79.2%). DISCUSSION: Removing structural economic barriers for people using public insurance may increase health equity in contraceptive access and choice.

Early life blood lead levels and asthma diagnosis at age 4-6 years.

The USA has a high burden of childhood asthma. Previous studies have observed associations between higher blood lead levels and greater hypersensitivity in children. The objective of the present study was to estimate the association between blood lead concentrations during early childhood and an asthma diagnosis between 48 and 72 months of age amongst a cohort with well-characterized blood lead concentrations. Blood lead concentrations were measured at 6, 12, 18, 24, 36, and 48 months of age in 222 children. The presence of an asthma diagnosis between 48 and 72 months was assessed using a questionnaire which asked parents or guardians whether they had been told by a physician, in the past 12 months, that their child had asthma. Crude and adjusted risk ratios (RR) of an asthma diagnosis were estimated for several parameterizations of blood lead exposure including lifetime average (6 to 48 months) and infancy average (6 to 24 months) concentrations. After adjustment for child sex, birthweight, daycare attendance, maternal race, education, parity, breastfeeding, income, and household smoking, age-specific or composite measures of blood lead were not associated with asthma diagnosis by 72 months of age in this cohort.

Maternal pre-pregnancy body mass index, gestational weight gain and breastfeeding outcomes: a cross-sectional analysis.

BACKGROUND: It is well established that mothers with above-normal pre-pregnancy BMI are at increased risk of breastfeeding cessation; however, the impact of pregnancy weight-gain (PWG) is less well-defined. Excess PWG may alter the hormonal preparation of breast tissue for lactation, increase the risk of complications that negatively impact breastfeeding (e.g. Cesarean-section, gestational diabetes), and may make effective latch more difficult to achieve. METHODS: Our objective was to determine the impact of PWG and pre-pregnancy BMI on the risk of breastfeeding cessation utilizing the Institute of Medicine's 2009 recommendations. Cox proportional hazards models were utilized to estimate the risk of cessation of exclusive breastfeeding, and cessation of any breastfeeding among women who initiated exclusive and any breastfeeding, respectively, in a cross sectional sample of survey respondents from a New York county (N = 1207). PWG category was interacted with pre-pregnancy BMI (3 levels of pre-pregnancy BMI, 3 levels of PWG). Confounders of the relationship of interest were evaluated using directed acyclic graphs and bivariate analyses; variables not on the proposed causal pathway and associated with the exposure and outcome were included in multivariate models. RESULTS: After adjustment, women of normal and obese pre-pregnancy BMI with greater-than-recommended PWG had 1.39 (1.03-1.86) and 1.48 (1.06-2.07) times the risk of any breastfeeding cessation within the first 3 months postpartum compared to women with normal pre-pregnancy BMI who gained within PWG recommendations. Overweight women with greater-than-recommended PWG were at increased risk of cessation, although not significantly (aHR [95% CI]: 1.29 [0.95-1.75]). No significant relationship was observed for exclusive breastfeeding cessation. CONCLUSIONS: Pre-pregnancy BMI and PWG may be modifiable risk factors for early breastfeeding cessation. Understanding the mechanism behind this risk should be ascertained by additional studies aimed at understanding the physiological, social, logistical (positioning) and other issues that may lead to early breastfeeding cessation.

Ambient wintertime particulate air pollution and hypertensive disorders of pregnancy in Monroe County, New York.

BACKGROUND: Previous studies have reported associations between ambient fine particle (PM2.5) concentrations and hypertensive disorders of pregnancy (HDP). However, none have examined whether ultrafine particles (UFP; < 100 nm), accumulation mode particles (AMP; 100-500 nm), markers of traffic pollution (black carbon; BC), or wood burning (Delta-C; (30% of ambient wintertime PM2.5 in Monroe County, NY is from wood burning)) are associated with an increased odds of HDP. We estimated the odds of HDP associated with increased concentrations of PM2.5, UFP, AMP, BC, and Delta-C in each gestational month during winter months. METHODS: Electronic medical records and birth certificate data were linked with land-use regression models in Monroe County, New York in 2009-2013 to predict monthly pollutant concentrations during winter (November-April) based on maternal residential address for 16,637 births. Using multivariable logistic regression, we estimated the odds of HDP associated with each interquartile range (IQR) increase in PM2.5, UFP, AMP, BC, and Delta-C concentrations during each gestational month, adjusting for maternal characteristics, birth hospital, temperature, and relative humidity. RESULTS: Each 0.52 µg/m3 increase in Delta-C concentration during the 7th gestational month was associated with an increased odds of HDP (odds ratio (OR) = 1.21; 95% confidence interval (CI) = 1.01, 1.45), with a similar sized estimate in month 8 (OR = 1.18; 95%CI = 0.98, 1.43). Non-statistically significant increased odds of HDP associated with IQR increases in BC concentrations during months 3 (OR = 1.12; 95%CI = 0.98, 1.28) and 7 (OR = 1.12; 95%CI = 0.96, 1.29) were observed. Increased odds of HDP were not observed for PM2.5, UFP, or AMP. CONCLUSIONS: Our findings suggest that maternal exposure to wood smoke in Monroe County during winter is associated with an increased odds of HDP during late gestation. Additional studies are needed to evaluate the effect of wood smoke on HDP and to explore effects on other pregnancy outcomes.

Changes in triggering of ST-elevation myocardial infarction by particulate air pollution in Monroe County, New York over time: a case-crossover study.

BACKGROUND: Previous studies have reported that fine particle (PM2.5) concentrations triggered ST elevation myocardial infarctions (STEMI). In Rochester, NY, multiple air quality policies and economic changes/influences from 2008 to 2013 led to decreased concentrations of PM2.5 and its major constituents (SO42-, NO3-, elemental and primary organic carbon). This study examined whether the rate of STEMI associated with increased ambient gaseous and PM component concentrations was different AFTER these air quality policies and economic changes (2014-2016), compared to DURING (2008-2013) and BEFORE these polices and changes (2005-2007). METHODS: Using 921 STEMIs treated at the University of Rochester Medical Center (2005-2016) and a case-crossover design, we examined whether the rate of STEMI associated with increased PM2.5, ultrafine particles (UFP, < 100 nm), accumulation mode particles (AMP, 100-500 nm), black carbon, SO2, CO, and O3 concentrations in the previous 1-72 h was modified by the time period related to these pollutant source changes (BEFORE, DURING, AFTER). RESULTS: Each interquartile range (3702 particles/cm3) increase in UFP concentration in the previous 1 h was associated with a 12% (95% CI = 3%, 22%) increase in the rate of STEMI. The effect size was larger in the AFTER period (26%) than the DURING (5%) or BEFORE periods (9%). There were similar patterns for black carbon and SO2. CONCLUSIONS: An increased rate of STEMI associated with UFP and other pollutant concentrations was higher in the AFTER period compared to the BEFORE and DURING periods. This may be due to changes in PM composition (e.g. higher secondary organic carbon and particle bound reactive oxygen species) following these air quality policies and economic changes.

Predicting Maintenance of Any Breastfeeding from Exclusive Breastfeeding Duration: A Replication Study.

OBJECTIVES: To predict the duration of any breastfeeding using the duration of exclusive breastfeeding in a socioeconomically heterogeneous sample of mothers using receiver operator characteristic (ROC) analysis. STUDY DESIGN: The Mother Baby Health Survey, a birth certificate-linked cross-sectional survey was sent at 4-5 months postpartum to a stratified random sample of socioeconomically and racially diverse women in upstate New York; 797 mothers who initiated exclusive breastfeeding were included in this study. Split-sample validation was employed; eligible subjects were divided into training or test samples at random (80% and 20%, respectively). ROC curves were constructed using the training sample and optimal exclusive breastfeeding duration thresholds were tested using the remaining test sample. Logistic regression using the training sample provided estimates of the predictive ability (sensitivity, specificity, positive predictive value) of thresholds in both unadjusted and adjusted analyses (covariates: age, education, parity, marital status, and race). RESULTS: The ROC analysis in this sample demonstrated that 9 weeks of exclusivity was required for maintenance of breastfeeding at 3 months, and 14.9 weeks of exclusivity was required for maintenance at 20 weeks. Unadjusted and adjusted models yielded similar results; women who exclusively breastfed for at least 9 weeks had 2.2 times the risk (95% CI 1.7-2.8) of maintaining any breastfeeding at 3 months. CONCLUSIONS: These results are similar to our previous results, from a less diverse cohort, and support that these thresholds may be useful in clinical settings for helping mothers achieve breastfeeding duration goals.

Examining Associations Between Strangulation and Depressive Symptoms in Women With Intimate Partner Violence Histories.

Intimate partner violence (IPV) is associated with poor mental health outcomes among women. Studies on IPV and mental health show that experiencing more than one type of IPV often enhances women's depression or depressive symptoms. However, most of these studies conceptualize IPV as physical, psychological, or sexual violence. Little is known about specific experiences of severe IPV, such as strangulation, that put victims at greater risk of lethality and serious injury and their association with women's depression. This study examined associations between IPV, strangulation, and depression among women using secondary data collected for a randomized clinical trial testing an integrated HIV-IPV prevention intervention for abused women. Women were recruited from healthcare service delivery organizations, Department of Health and Human Services, and family court. Women (n = 175) completed assessments on IPV, strangulation, mental health, social support, and self-esteem. The majority reported strangulation (n = 103) and depressive symptoms (n = 101). Women who experienced strangulation also reported more severe physical (p < .001), sexual (p < .001), and psychological (p < .001) abuse. However, in multivariate logistic regression with sociodemographics, violence variables, and strangulation, none of these variables were associated with a higher risk for depressive symptoms. Social support had a protective effect on depressive symptoms. Findings suggest strangulation is prevalent among abused women seeking services, warranting screening, assessment, and referral in these settings.

An Integrated HIV Risk Reduction Intervention for Women with a History of Intimate Partner Violence: Pilot Test Results.

There are few HIV risk reduction interventions to meet the unique needs of women who experience intimate partner violence (IPV). This pilot study tested the feasibility, safety, and preliminary effects of an integrated IPV-sexual risk reduction intervention for abused women. Fifty-five women were randomized to the supporting positive and healthy relationships (SUPPORT) intervention (n = 27) or to a control group (n = 28). Assessments were conducted pre- and post-intervention and at 3-month follow-up. Post-intervention, SUPPORT participants showed a significant decrease in frequency of unprotected sex and an increase in safer sex communications with steady and other sexual partners. Compared to the control group, SUPPORT participants reported a higher number of safer sex conversations with their steady partner at the 3-month follow-up, and fewer episodes of IPV at both assessments in comparison to baseline. They showed improvements in sexual relationship power at both follow-ups and in several hypothesized antecedents of HIV-risk behavior. These encouraging preliminary findings suggest the need for a larger clinical trial.

Associations between ambient wood smoke and other particulate pollutants and biomarkers of systemic inflammation, coagulation and thrombosis in cardiac patients.

BACKGROUND: Increased particulate air pollution has been associated with both an increased risk of myocardial infarction (MI) and adverse changes in cardiac biomarkers. Up to 30% of ambient wintertime fine particles (PM2.5) in Rochester, NY are from wood burning. Our study examined associations between ambient levels of a marker of wood smoke (Delta-C) and other particulate air pollutants and biomarkers of inflammation, coagulation and thrombosis. METHODS: We measured blood concentrations of C-reactive protein (CRP), D-dimer, fibrinogen, P-selectin, platelet factor 4 (PF-4), von Willebrand factor (vWF), and myeloperoxidase (MPO) of 135 patients undergoing cardiac catheterization during the winters of 2011-2013. We coupled these data with hourly ambient concentrations of Delta-C, black carbon (BC; marker of traffic pollution), and ultrafine (10-100nm; UFP), accumulation mode (100-500nm; AMP), and fine particles (<2.5µm; PM2.5). Using linear regression models, we estimated the change in each biomarker associated with increased pollutant concentrations at intervals between 1 and 96h preceding blood collection. RESULTS: Each 0.13µg/m3 increase in Delta-C concentration in the prior 12h was associated with a 0.91% increase in fibrinogen levels (95% CI=0.23%, 1.59%), but unexpectedly in the prior 48h, each 0.17µg/m3 increase in Delta-C concentration was associated with a 2.75% decrease in MPO levels (95% CI=-5.13%,-0.37%). We did not see associations between Delta-C concentrations and any other biomarkers. Interquartile range (IQR) increases in PM2.5, BC, UFP, and AMP concentrations were generally associated with increased CRP and fibrinogen, but not PF4, D-dimer, vWF, or P-selectin. CONCLUSIONS: In a population of cardiac patients, we noted adverse changes in fibrinogen associated with increased concentrations of a marker of wood smoke. Increases in PM2.5, BC, AMP, and UFP concentrations in the previous 96h were also associated with adverse changes in markers of systemic inflammation and coagulation, but not with markers of endothelial cell dysfunction or platelet activation.

Demographic, Reproductive, and Dietary Determinants of Perfluorooctane Sulfonic (PFOS) and Perfluorooctanoic Acid (PFOA) Concentrations in Human Colostrum.

To determine demographic, reproductive, and maternal dietary factors that predict perfluoroalkyl substance (PFAS) concentrations in breast milk, we measured perfluorooctane sulfonic (PFOS) and perfluorooctanoic acid (PFOA) concentrations, using liquid chromatography-mass spectrometry, in 184 colostrum samples collected from women participating in a cohort study in Eastern Slovakia between 2002 and 2004. During their hospital delivery stay, mothers completed a food frequency questionnaire, and demographic and reproductive data were also collected. PFOS and PFOA predictors were identified by optimizing multiple linear regression models using Akaike's information criterion (AIC). The geometric mean concentration in colostrum was 35.3 pg/mL for PFOS and 32.8 pg/mL for PFOA. In multivariable models, parous women had 40% lower PFOS (95% CI: -56 to -17%) and 40% lower PFOA (95% CI: -54 to -23%) concentrations compared with nulliparous women. Moreover, fresh/frozen fish consumption, longer birth intervals, and Slovak ethnicity were associated with higher PFOS and PFOA concentrations in colostrum. These results will help guide the design of future epidemiologic studies examining milk PFAS concentrations in relation to health end points in children.

Optimal periods of exclusive breastfeeding associated with any breastfeeding duration through one year.

OBJECTIVE: To quantify optimal minimum durations of exclusive breastfeeding associated with maintenance of any breastfeeding at 15 time points during the first year of life. STUDY DESIGN: Mothers (n = 1189) from the prospective Infant Feeding Practices Study II cohort who initiated exclusive breastfeeding with healthy term infants were included. In a 80:20 split-sample validation study, receiver operating characteristic curves estimated optimal minimum durations of exclusive breastfeeding needed to predict maintenance of any breastfeeding at 15 time points during the first year (n = 951). Logistic regression estimated the predictive performance of the identified thresholds adjusted for maternal age, race, education, parity, support system, and return-to-work status. Results were validated in the remaining 20% (n = 238). RESULTS: Optimal minimum durations ranged from 4.0-17.1 weeks of exclusive breastfeeding associated with maintenance of any breastfeeding at 15 time points. All estimated threshold durations were statistically significant after adjustment. CONCLUSIONS: Using a methodological approach unique to breastfeeding duration research, the authors report optimal durations of exclusive breastfeeding associated with duration of any breastfeeding at time points throughout the first year. Perinatal clinicians, pediatricians, lactation professionals, policymakers, researchers, and families might apply these findings to achieve desirable collective breastfeeding duration outcomes.

Images of a Healthy Worksite: A Group-Randomized Trial for Worksite Weight Gain Prevention With Employee Participation in Intervention Design.

OBJECTIVES: We assessed the effects of a worksite multiple-component intervention addressing diet and physical activity on employees' mean body mass index (BMI) and the percentage of employees who were overweight or obese. METHODS: This group-randomized trial (n = 3799) was conducted at 10 worksites in the northeastern United States. Worksites were paired and allocated into intervention and control conditions. Within- and between-groups changes in mean BMIs and in the percentage of overweight or obese employees were examined in a volunteer sample. RESULTS: Within-group mean BMIs decreased by 0.54 kilograms per meter squared (P = .02) and 0.12 kilograms per meter squared (P = .73) at the intervention and control worksites, respectively, resulting in a difference in differences (DID) decrease of 0.42 kilograms per meter squared (P = .33). The within-group percentage of overweight or obese employees decreased by 3.7% (P = .07) at the intervention worksites and increased by 4.9% (P = .1) at the control worksites, resulting in a DID decline of 8.6% (P = .02). CONCLUSIONS: Our findings support a worksite population strategy that might eventually reduce the prevalence of overweight and obesity by minimizing environmental exposures to calorically dense foods and increasing exposures to opportunities for energy expenditure within worksite settings.

Tuberculosis screening for patients on biologic Medications: A Single-Center experience and Society guideline Review, Monroe County, New York, 2018-2021.

Rationale: Biologic medications for immune-mediated inflammatory diseases may increase the risk of tuberculosis (TB) reactivation, but data on screening for TB in low TB prevalence areas are limited. Objective: To assess the real-world practice patterns of TB screening among prescribers of biologic medications. Methods: We conducted a retrospective observational study at a single, university-based healthcare facility in a low TB prevalence area. We enrolled adult patients prescribed a biologic medication between October 2018 and December 2021, and collected data on demographics, biologic medications and TB test results. For patients with positive TB tests, further data including prescriber specialty and response to positive tests were obtained. We reviewed pertinent major society guidelines/ consensus statements regarding TB screening among patients treated with biologic medications. Results: 4,085 patients were included. 3024 (74.0%) had at least one screening TB test and 42 were positive. Among patients treated with tumor necrosis factor-alpha (TNFα) inhibitors, 1779 of 2129 patients (83.6%) underwent TB testing and 25 (1.4%) were positive. Most with positive TB test results were prescribed biologic medication by gastroenterology (11 patients, 26%), dermatology (12, 29%), or rheumatology (15, 36%) providers. 32 (76%) patients had imaging and roughly half were treated for latent TB infection. Biologic medications were temporarily held for 27 patients (67%). Nine out of 13 society guidelines recommend TB screening for TNFα inhibitors but have differing recommendations for other biologic medications. Conclusions: Significant practice pattern differences in TB screening for patients receiving biologic medications exist. Multiple society guidelines continue to recommend TB screening even for drugs with no known increased risk of TB reactivation.

Cost-effectiveness of cardiac resynchronization therapy in the MADIT-CRT trial.

BACKGROUND: The Multicenter Automatic Defibrillator Implantation Trial-Cardiac Resynchronization Therapy (MADIT-CRT) trial demonstrated that cardiac resynchronization therapy (CRT) when added to the implantable cardiac defibrillator (ICD) reduces risk of heart failure or death in minimally symptomatic patients with reduced cardiac ejection fraction and wide QRS complex. OBJECTIVES: To evaluate 4-year cost-effectiveness of CRT-ICD compared to ICD alone using MADIT-CRT data. RESEARCH DESIGN: Patients enrolled in the trial were randomized to implantation of either ICD or CRT-ICD in a 2:3 ratio, with up to 4-year follow-up period. Cost-effectiveness analyses were conducted, and sensitivity analyses by age, gender, and left bundle branch block (LBBB) conduction pattern were performed. SUBJECTS: A total of 1,271 patients with ICD or CRT-ICD (US centers only) who reported healthcare utilization and health-related quality of life data. MEASURES: We used the EQ-5D (US weights) to assess patient HRQOL and translated utilization data to costs using national Medicare reimbursement rates. RESULTS: Average 4-year healthcare expenditures in CRT-ICD patients were higher than costs of ICD patients ($62,600 vs 57,050, P = 0.015), mainly due to the device and implant-related costs. The incremental cost-effectiveness ratio of CRT-ICD compared to ICD was $58,330/quality-adjusted life years (QALY) saved. The cost effectiveness improved with longer time horizon and for the LBBB subgroup ($7,320/QALY), with no cost-effectiveness benefit being evident in the non-LBBB group. CONCLUSIONS: In minimally symptomatic patients with low ejection fraction and LBBB, CRT-ICD is cost effective within 4-year horizon when compared to ICD-only.

The triggering of myocardial infarction by fine particles is enhanced when particles are enriched in secondary species.

Previous studies have reported an increased risk of myocardial infarction (MI) associated with acute increases in PM concentration. Recently, we reported that MI/fine particle (PM2.5) associations may be limited to transmural infarctions. In this study, we retained data on hospital discharges with a primary diagnosis of acute myocardial infarction (using International Classification of Diseases ninth Revision [ICD-9] codes), for those admitted January 1, 2004 to December 31, 2006, who were ≥ 18 years of age, and were residents of New Jersey at the time of their MI. We excluded MI with a diagnosis of a previous MI and MI coded as a subendocardial infarction, leaving n = 1563 transmural infarctions available for analysis. We coupled these health data with PM2.5 species concentrations predicted by the Community Multiscale Air Quality chemical transport model, ambient PM2.5 concentrations, and used the same case-crossover methods to evaluate whether the relative odds of transmural MI associated with increased PM2.5 concentration is modified by the PM2.5 composition/mixture (i.e., mass fractions of sulfate, nitrate, elemental carbon, organic carbon, and ammonium). We found the largest relative odds estimates on the days with the highest tertile of sulfate mass fraction (OR = 1.13; 95% CI = 1.00, 1.27), nitrate mass fraction (OR = 1.18; 95% CI = 0.98, 1.35), and ammonium mass fraction (OR = 1.13; 95% CI = 1.00 1.28), and the lowest tertile of EC mass fraction (OR = 1.17; 95% CI = 1.03, 1.34). Air pollution mixtures on these days were enhanced in pollutants formed through atmospheric chemistry (i.e., secondary PM2.5) and depleted in primary pollutants (e.g., EC). When mixtures were laden with secondary PM species (sulfate, nitrate, and/or organics), we observed larger relative odds of myocardial infarction associated with increased PM2.5 concentrations. Further work is needed to confirm these findings and examine which secondary PM2.5 component(s) is/are responsible for an acute MI response.

Labor epidural anesthesia, obstetric factors and breastfeeding cessation.

Breastfeeding benefits both infant and maternal health. Use of epidural anesthesia during labor is increasingly common and may interfere with breastfeeding. Studies analyzing epidural anesthesia's association with breastfeeding outcomes show mixed results; many have methodological flaws. We analyzed potential associations between epidural anesthesia and overall breast-feeding cessation within 30 days postpartum while adjusting for standard and novel covariates and uniquely accounting for labor induction. A pooled analysis using Kaplan-Meier curves and modified Cox Proportional Hazard models included 772 breastfeeding mothers from upstate New York who had vaginal term births of healthy singleton infants. Subjects were drawn from two cohort studies (recruited postpartum between 2005 and 2008) and included maternal self-report and maternal and infant medical record data. Analyses of potential associations between epidural anesthesia and overall breastfeeding cessation within 1 month included additional covariates and uniquely accounted for labor induction. After adjusting for standard demographics and intrapartum factors, epidural anesthesia significantly predicted breastfeeding cessation (hazard ratio 1.26 [95% confidence interval 1.10, 1.44], p < 0.01) as did hospital type, maternal age, income, education, planned breastfeeding goal, and breastfeeding confidence. In post hoc analyses stratified by Baby Friendly Hospital (BFH) status, epidural anesthesia significantly predicted breastfeeding cessation (BFH: 1.19 [1.01, 1.41], p < 0.04; non-BFH: 1.65 [1.31, 2.08], p < 0.01). A relationship between epidural anesthesia and breastfeeding was found but is complex and involves institutional, clinical, maternal and infant factors. These findings have implications for clinical care and hospital policies and point to the need for prospective studies.

Identifying barriers individuals face in accessing fertility care after a gynecologic cancer diagnosis.

Objective: To (1) identify the major barriers premenopausal individuals face in accessing fertility care at the time of gynecologic cancer diagnosis and (2) to assess patient experiences pertaining to fertility. Methods: We distributed an online survey about cancer diagnosis and fertility goals to patients ages 18-40 who had been treated for ovarian, endometrial, or cervical cancer at a single, large academic hospital. Descriptive statistics were used to analyze survey results. Patients who completed the survey were given the option to participate in a follow-up virtual interview. We conducted semi-structured interviews to discuss their fertility goals and barriers to these. Grounded theory was used to qualitatively analyze the interviews. Results: Fifty-five patients completed the survey, and 20 patients participated in the interview. The median age at diagnosis was 32 years old. Seventy-three percent of patients recalled that at the time of their diagnosis they were considering future childbearing, and 32% underwent fertility preservation. Patients reported the emotional response to their diagnosis as a barrier to receiving fertility care, with patients reporting lack of control (80%), shock (55%), and confusion (45%). Patients also identified inadequate counseling (60.0%), lack of time (60.0%), economic constraints (55.0%) and prioritization of cancer treatment (55.0%) as barriers. Nearly all patients had a positive interview experience and expressed desire to help patients in similar situations. Conclusion: Many premenopausal patients diagnosed with gynecologic malignancies are considering future childbearing at the time of diagnosis. Both logistical and emotional barriers prevent them from undergoing fertility preservation before initiating oncologic treatment.

Trends and Non-Clinical Predictors of Respiratory Syncytial Virus (RSV) and Influenza Diagnosis in an Urban Pediatric Population.

Objective: To evaluate the demographic, maternal, and community-level predictors of pediatric respiratory syncytial virus (RSV) and influenza diagnosis among an urban population of children residing in Rochester, NY. Study design: A test-negative case-control design was used to investigate various non-clinical determinants of RSV and influenza diagnosis among 1,808 children aged 0-14 years who presented to the University of Rochester Medical Center (URMC) or an affiliated health clinic in Rochester, NY between 2012-2019. These children were all tested for RSV and influenza via polymerase-chain-reaction (PCR) method, including RSV and influenza diagnosis of all severity types. Test results were linked to medical records, birth certificates, questionnaires administered through the Statewide Perinatal Data System, and the US census by census tracts to obtain information on child, maternal, demographic, and socio-economic characteristics. Results: Overall the strongest predictor of RSV and influenza diagnosis was child's age, with every year increase in child's age, risk for RSV decreased (OR: 0.75; 95% CI: 0.71, 0.79) and risk for influenza increased (OR: 1.20; 95%: 1.16, 1.24). In addition to age, non-private insurance type was positively associated with influenza diagnosis. When considering the proportion of positive cases for RSV and influenza over all PCR tests by respiratory season, a spike in influenza cases was observed in 2018-2019. Conclusions: Age was a strong predictor of RSV and influenza diagnosis among this urban sample of children.
