Accuracy of Self-Reported Vaccination Status in a Cohort of Patients with Inflammatory Bowel Disease.

BACKGROUND AND AIMS: Prevention of vaccine-preventable diseases is important in the care of patients with inflammatory bowel disease (IBD). Thus, accurate immunization histories are critical. Many providers rely on patient self-report when assessing immunization status. The primary aim of our study was to determine the accuracy of self-reported influenza vaccination status in a cohort of patients with IBD. METHODS: We conducted a prospective study of patients with IBD who answered a vaccination status questionnaire and compared their responses to the Wisconsin Immunization Registry, a state-wide electronic immunization information system. The primary outcome was the sensitivity and specificity of self-reported influenza vaccination status. A secondary outcome evaluated the sensitivity and specificity of pneumococcal vaccination status. RESULTS: A total of 200 patients with IBD were included in the study. Documented immunization rates were 74.5% for influenza vaccinations and 79.9% for pneumococcal vaccinations. Influenza vaccination self-report had a sensitivity of 98.7%, a specificity of 90.2%, a positive predictive value (PPV) of 96.7% and a negative predictive value (NPV) of 95.8%. In comparison, the sensitivity for pneumococcal vaccination was 83.5% with a specificity of 86.2%, PPV of 96.4%, and NPV of 54.3%. CONCLUSIONS: Self-reported influenza immunization status is sensitive and specific in patients with IBD. Accuracy for pneumococcal vaccination is slightly lower, but responses were notable for a high PPV. Self-report is an effective way to determine influenza immunization status and provides useful information for receipt of pneumococcal vaccine in patients with IBD.

Comparison of International Ovarian Tumor Analysis Simple Rules to Society of Radiologists in Ultrasound Guidelines for Detection of Malignancy in Adnexal Cysts.

OBJECTIVE. The purpose of this study was to evaluate the International Ovarian Tumor Analysis (IOTA) simple rules and the Society of Radiologists in Ultrasound (SRU) guidelines for detecting ovarian malignancy in a general population of women presenting to radiology departments with adnexal cystic lesions. MATERIALS AND METHODS. A retrospective multicenter study of ultrasound-detected adnexal cystic lesions with appropriate follow-up was conducted. Lesions were classified into benign, indeterminate, or malignant categories according to criteria based on the IOTA simple rules and the SRU guidelines. The prevalence of nonneoplastic cysts, neoplasms, and malignant tumors was calculated. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy were calculated, and ROC analysis for the diagnosis of malignancy was performed. RESULTS. A total of 697 women with 764 cystic lesions were included; 85.2% (651/764) of the lesions were nonneoplastic, 12.2% (93/764) were benign neoplasms, and 2.6% (20/764) were malignant neoplasms. Nearly all malignancies were classified into indeterminate and malignant categories. The prevalence of malignancy in the indeterminate category was 4.8% (7/145) (SRU) to 10.7% (7/65) (IOTA) and in the malignant category was 18.1% (13/72) (SRU) to 34.3% (12/35) (IOTA). Only one malignancy was misclassified as benign by the IOTA simple rules. The sensitivity of the IOTA simple rules for malignancy was 90.0%; specificity, 96.5%; PPV, 29.0%; NPV, 99.8%; and accuracy, 96.4%. The corresponding values for the SRU guidelines were 100%, 89.6%, 14.9%, 100%, and 89.8%. In ROC analysis, the IOTA simple rules were slightly more accurate than the SRU guidelines (AUC, 0.9805 versus 0.9713; p = 0.0003). CONCLUSION. Both imaging characterization methods were sensitive for identifying ovarian malignancies, but the PPV was low among women presenting to radiology departments, and the indeterminate classification harbored one-third of the total malignancies. Exploration of varied clinical settings and inclusion of secondary tests may help to refine these systems.

Indeterminate Adnexal Cysts at US: Prevalence and Characteristics of Ovarian Cancer.

Purpose To assess the prevalence of indeterminate adnexal cysts in women presenting to academic medical centers for pelvic ultrasonography (US), determine the incidence of malignancy, and identify cyst and patient characteristics that are predictive of malignancy. Materials and Methods A multicenter study of US-detected adnexal cysts with appropriate follow-up (surgical pathologic examination, imaging and/or clinical examination) was conducted from January 2008 to June 2012. Indeterminate cysts were classified as category 1 (typical benign appearing cysts >5 cm) or category 2 (cysts with avascular solid components) on the basis of a combination of definitions in the existing literature. The incidence of neoplasms and malignant tumors was calculated. Patient and cyst characteristics associated with neoplasm and malignant tumors were evaluated with the χ2 test or Fisher exact test for categorical variables and the t test for continuous variables. A backward stepwise logistic regression model was performed for two outcomes: (a) the presence of any neoplasm (benign or malignant) and (b) the presence of a malignant tumor. Results There were 1637 women with an adnexal cyst at US; 391 (mean age = 41.8 years ± 13.5.1; range = 17-91 years) had an indeterminate adnexal cyst at US. The prevalence of indeterminate adnexal cysts was 23.9% (391 of 1637; 95% confidence interval [CI]: 0.22, 0.26). Three hundred three indeterminate cysts in 280 women (mean age = 42.9 years ± 14.1; range = 17-88 years) had adequate follow-up. The incidence of ovarian neoplasms (benign and malignant) was 24.8% (75 of 303 cysts; 95% CI: 0.20, 0.30), and the incidence of malignant tumors was 3.6% (11 of 303 cysts; 95% CI: 0.02, 0.06). The proportion of ovarian neoplasms differed between category 1 and category 2 cysts (17.5% [25 of 143 cysts; 95% CI: 0.12, 0.25] vs 31.3% [50 of 160 cysts; 95% CI: 0.24, 0.39], respectively; P = .001). The proportion of malignant tumors differed between categories 1 and 2 cysts (0% [0 of 143 cysts] vs 6.9% [11 of 160 cysts; 95% CI: 0.03, 0.12]; P < .001). The presence of an avascular nodular component was a significant predictor of malignancy at stepwise logistic regression analysis (odds ratio = 2.83; P ≤ .0001; 95% CI: 1.69, 4.70). Conclusion The presence of an avascular nodular component was the most significant predictor of the presence of malignancy in indeterminate adnexal cysts. The risk of malignancy is higher with category 2 cysts than with category 1 cysts. © RSNA, 2018.

Neoadjuvant chemotherapy is associated with a high rate of perioperative blood transfusion at the time of interval cytoreductive surgery.

BACKGROUND: The oncologic safety of allogeneic blood transfusion in ovarian cancer patients is unknow. We sought to determine the prevalence and oncologic safety of perioperative allogeneic blood transfusion during interval cytoreduction surgery among women receiving neoadjuvant chemotherapy for ovarian cancer. METHODS: We utilized retrospective chart review to identify a cohort of patients undergoing interval cytoreduction at a large academic tertiary referral center. We compared outcomes in patients who were exposed to perioperative blood transfusion compared with patients who were not exposed. Our primary endpoint was progression free survival; our secondary endpoint was overall survival. Baseline clinical characteristics were collected for patients in each group. RESULTS: Sixty-six women were included in the final cohort of women undergoing interval cytoreductive surgery after NACT. A total of 51 women (77%) were exposed to allogeneic perioperative pRBC transfusion. Fifteen women (23%) were not exposed to transfusion. The baseline characteristics were generally well matched. Women who were not exposed to a perioperative blood transfusion were more likely to have a normalized CA125 prior to undergoing cytoreductive surgery. Preoperative hemoglobin concentration was lower in the transfusion group (10.5 g/dLvs 11.5 g/dL, p < 0.009). Perioperative transfusion was not associated with a significant difference in progression free survival (PFS = 7.6 months for transfused, 9.4 months for not transfused; log-rank test p = 0.4617). Similarly, there was no observed difference between groups for overall survival (OS = 23.6 months for transfused, 22.5 months for not transfused; log-rank test p = 0.1723). CONCLUSIONS: Women undergoing neoadjuvant chemotherapy for ovarian cancer are at high risk of exposure to blood transfusion at the time of interval cytoreductive surgery. Future studies will continue to evaluate the safety and impact of transfusion on ovarian cancer survival in this at risk population.

Peri-operative allogeneic blood transfusion is associated with poor overall survival in advanced epithelial ovarian Cancer; potential impact of patient blood management on Cancer outcomes.

BACKGROUND: Transfusion related immune modulation associated with red blood cell (RBC) transfusion is thought to result in decreased cancer survival. Results in epithelial ovarian cancer (EOC) have been mixed however most suggest worse oncologic outcomes in patients who were transfused at the time of debulking surgery. The impact of restrictive transfusion strategies on this patient population is currently not known. METHODS: We conducted a retrospective study of women with EOC. The study population was divided into two groups based on whether they were transfused RBCs during the peri-operative period or not. Clinical characteristics and prognosticators were compared between groups. Overall survival was compared between groups based on transfusion status and other known prognostic factors. Cox proportional hazard modeling was used to examine the association between the prognostic factors and the study endpoint. RESULTS: Sixty-six percent of women were transfused. Transfusion was associated with CA125, the use of neoadjuvant chemotherapy (NACT), surgical blood loss, and anemia. The mean pre-transfusion Hgb was 7.8 + 0.6 g/dL and 94% had a hemoglobin level greater than the transfusion threshold of 7 g/dL. RBC transfusion, suboptimal debulking, anemia, and NACT were associated with decreased survival. Only RBC transfusion and suboptimal debulking status remained significant in a multivariate model. CONCLUSIONS: Peri-operative RBC transfusion compromises survival in ovarian cancer supporting the need to minimize the use of transfusion at the time of debulking surgery. Adherence to evidence-based transfusion guidelines offers an opportunity to reduce transfusion rates in this population with a resulting positive influence on survival.

Neoadjuvant chemotherapy is associated with more anemia and perioperative blood transfusions than primary debulking surgery in women with advanced stage ovarian cancer.

OBJECTIVE: The purpose of this case-controlled study was to determine the prevalence of anemia and incidence of perioperative blood transfusions in patients undergoing treatment for advanced ovarian cancer with neoadjuvant chemotherapy (NACT) or primary debulking surgery (PDS). METHODS: We performed a single institution review of patients diagnosed with stage IIIB-IVB epithelial ovarian cancer between 2010 and 2013 undergoing either NACT or PDS. Anemia was defined as a hemoglobin (Hgb) concentration of ≤11.5 g/dL. Continuous variables were compared by student t-test and binary variables compared via chi square analysis. RESULTS: One hundred thirty-one women were included, 66 treated with NACT and 65 treated with PDS. Average Hgb prior to surgery was lower in women who received NACT (10.7 g/dL vs 12.8 g/dL, p < 0.0001). Women treated with NACT had a decrease in mean Hgb during chemotherapy treatment (11.8 g/dL at diagnosis to 10.7 g/dL preoperatively). Seventy-seven percent of NACT patients were anemic prior to surgery compared to 15% of patients prior to PDS (p < 0.001). Mean EBL at debulking was higher in patients selected for PDS (871 mL) than NACT (544 mL); however, the perioperative transfusion rate was higher during interval debulking surgeries (NACT 77% vs PDS 56%, p = 0.01). CONCLUSION: Women selected for NACT were more likely to be anemic at diagnosis and became progressively anemic during NACT. Despite less blood loss during debulking surgery, NACT patients receive more blood transfusions perioperatively than patients undergoing PDS. This represents a potential opportunity for therapeutic intervention during NACT to correct anemia prior to interval debulking surgery.

Renin-angiotensin system transgenic mouse model recapitulates pathophysiology similar to human preeclampsia with renal injury that may be mediated through VEGF.

Using a transgenic cross, we evaluated features of preeclampsia, renal injury and the sFlt1/VEGF changes. Transgenic hAGT and hREN, or wild-type (WT) C57Bl/6 mice were cross-bred: female hAGT × male hREN for preeclampsia (PRE) model and female WT × male WT for pregnant controls (WTP). Samples were collected for plasma VEGF, sFlt1, and urine albumin. Blood pressures (BP) were monitored by telemetry. Vascular reactivity was investigated by wire myography. Kidneys and placenta were immunostained for sFlt1 and VEGF. Eleven PRE and 9 WTP mice were compared. PRE more frequently demonstrated albuminuria, glomerular endotheliosis (80% vs. 11%; P = 0.02), and placental necrosis (60% vs. 0%; P < 0.01). PRE group demonstrated declining BPs with advancing gestation. Plasma sFlt1 increased across pregnancy in PRE; VEGF did not vary. IHC demonstrated the presence of sFlt1 in glomeruli, lymphatics, and collecting tubules of PRE kidneys, suggesting excretion. VEGF immunostaining was increased specifically in the glomeruli of PRE kidneys. Placenta in PRE showed marked immunostaining for sFlt1. We conclude that this transgenic model of preeclampsia recapitulates human preeclamptic state with high fidelity, and that, vascular adaptation to pregnancy is suggested by declining BPs and reduced vascular response to PE and increased response to acetylcholine. Placental damage with resultant increased release of sFlt1, proteinuria, deficient spiral artery remodeling, and glomerular endotheliosis were observed in this model of PRE. Increased VEGF binding to glomerular endothelial cells in this model of PRE is similar to human PRE and leads us to hypothesize that renal injury in preeclampsia may be mediated through local VEGF.

The TOTAL trial for weight management participation: A randomized controlled trial protocol.

BACKGROUND: The three types of evidence-based treatment options for adults with overweight and obesity - behavioral weight management, anti-obesity medications (AOM), and bariatric surgery - are underutilized in the Veterans Health Administration (VHA) system. Our objective in this manuscript is to describe the study protocol for an adequately powered randomized controlled trial (RCT) of a behavioral intervention: TOTAL (Teaching Obesity Treatment Options to Adult Learners) to increase patient uptake of obesity treatment. METHODS: In this multi-site, parallel, RCT, eligible Veterans with a body mass index [BMI] ≥ 27 who had not received obesity treatment within the past 12 months were randomly assigned to TOTAL or usual care. TOTAL involves watching an 18-min video that highlights obesity health risks, pros/cons of all three evidence-based obesity treatments, and expected treatment outcomes. It also includes motivational sessions delivered via televideo at 2 weeks, 6 months, and 12 months after the video (target n = 494 participants). The primary outcome is initiation of behavioral weight management treatment within 18 months of randomization. Secondary outcomes include sustained behavioral weight management treatment, initiation of AOM, bariatric surgery referral, and weight change across 18 months. CONCLUSION: TOTAL, which seeks to increase delivery of weight management treatment within the largest integrated health system in the U.S., combines patient education with motivational interviewing components. If efficacious in this trial, further evaluation of intervention effectiveness and implementation throughout the VHA and other healthcare systems would be warranted.

Hypocarnitinemia and its effect on seizure control in adult patients with intractable epilepsy on the modified Atkins diet.

Introduction: Previous studies have demonstrated the safety and efficacy of the modified Atkins diet (MAD) in attenuating seizures in patients with intractable epilepsy. MAD works by achieving ketosis, which is heavily dependent on the metabolic compound, carnitine, to facilitate the transport of long-chain fatty acids across the mitochondria for beta-oxidation. The effect of carnitine on ketogenic diet therapy is not well-defined in the current literature. Thus, the purpose of our study is to investigate the effects of hypocarnitinemia on the efficacy of MAD. Methods: A retrospective chart review was conducted, and 58 adults with epilepsy undergoing MAD were evaluated. Generalized linear mixed effects models were used to compare the low carnitine status with normal carnitine group in patient measures of body mass index, seizure frequency and severity, number of anti-seizure medications, beta-hydroxybutyrate, triglyceride, and carnitine levels across baseline, 3-9-month follow-up (timepoint 1), 1-2-year follow-up (timepoint 2), and 2+ year follow-up (timepoint 3). Results: Our study revealed that 38.3% of adult patients with epilepsy following MAD experienced low free carnitine at some point through the course of diet therapy. Patients with hypocarnitinemia at timepoint 2 showed a significant percent seizure increase while seizures continued to decrease in the normal carnitine group. Fasting triglyceride levels at timepoint 1 were significantly increased in the low carnitine group compared to normal carnitine group. Change in BHB, BMI, seizure severity, and number of ASMs showcased no significant differences between the low and normal carnitine groups. Discussion: It may be important for clinicians to monitor for hypocarnitinemia in adults on MAD and provide carnitine supplementation when low. Further investigations into carnitine and MAD may inform clinical decisions on carnitine supplementation to maximize the efficacy of MAD therapy.

Feline cutaneous lymphoma: an evaluation of disease presentation and factors affecting response to treatment.

OBJECTIVES: The primary goal of this study was to characterize the clinical presentation of feline cutaneous lymphoma. The secondary aims included determining if treatment or initial response to treatment affected the overall survival of patients, and understanding if disease characteristics such as immunophenotype, cell size or the presence of epitheliotropism influenced response to treatment. METHODS: Veterinary medical oncologists at four academic veterinary teaching hospitals submitted cases of feline patients with cutaneous lymphoma diagnosed by histopathology or cytology. Signalment, feline leukemia virus (FeLV)/feline immunodeficiency virus (FIV) status, physical examination findings, clinical signs, diagnostic tests, therapy, response and outcome, and necropsy findings, when available, were recorded. RESULTS: Forty-one patients were identified and described. The majority of patients were domestic shorthair cats (n = 29). The median age at diagnosis was 12.3 years. Males were over-represented in the population (n = 30). In the majority of patients (n = 33), the FIV/FeLV status was unknown. Twenty patients were fully staged. Thirty-four patients were treated with a variety of modalities, including surgery, radiation, single-agent or combination chemotherapy, or prednisolone only. In multiple patients, surgery or radiation was combined with a systemic therapy. Of 34 patients treated with some form of therapy, 20 responded (achieving either a partial response or complete remission). CONCLUSIONS AND RELEVANCE: Clinical signs and physical examination findings varied among patients. Response to therapy appeared to be associated with survival (P = 0.0025); however, this population was highly censored. Immunophenotype, cell size and the presence of epitheliotropism did not influence treatment response. Results were limited by small numbers of patients, heterogeneous disease manifestations and treatment protocols. Further studies are necessary to evaluate the effect of specific treatment modalities and disease subtype on prognosis.

Dysphagia Profiles Among Inpatients with Dementia Referred for Swallow Evaluation.

BACKGROUND: Alzheimer's disease and related dementias (ADRD) patients who are hospitalized often develop oropharyngeal dysphagia, increasing risk for adverse outcomes, such as aspiration pneumonia. However, prevalence estimates of dysphagia are highly variable and often based on patient report or clinical testing rather than visualization of the swallow. OBJECTIVE: The aims of this study were to determine prevalence and severity of dysphagia among inpatients with ADRD referred for swallowing evaluation. METHODS: Electronic health record (EHR) abstraction of ADRD diagnosis and presence and severity of clinically-determined dysphagia on bedside swallow evaluation (BSE) and videofluoroscopic swallow study (VFSS). RESULTS: 16% (n = 268) had an ADRD diagnosis or were taking dementia-specific medication based on the EHR. 75% (n = 202) were diagnosed with dysphagia on the BSE. 60% subsequently underwent VFSS (n = 122) with dysphagia confirmation in 92% (n = 112). ADRD inpatients were significantly more likely to be diagnosed with dysphagia based on the BSE (p < 0.0001) than those without ADRD. Additionally, dysphagia on the VFSS was more severe in the ADRD group (p < 0.03). DISCUSSION: ADRD individuals may be vulnerable to developing or worsening dysphagia during hospitalization. Results underscore the importance of evaluating swallowing function in hospitalized patients with ADRD in order to facilitate targeted intervention.

Impact of a Rheumatology Clinic Protocol on Tobacco Cessation Quit Line Referrals.

OBJECTIVE: Smoking increases cardiopulmonary and rheumatic disease risk, yet tobacco cessation intervention is rare in rheumatology clinics. This study aimed to implement a rheumatology staff-driven protocol, Quit Connect, to increase the rate of electronic referrals (e-referrals) to free, state-run tobacco quit lines. METHODS: We conducted a quasi-experimental cohort study of Quit Connect at 3 rheumatology clinics comparing tobacco quit line referrals from 4 baseline years to referrals during a 6-month intervention period. Nurses and medical assistants were trained to use 2 standardized electronic health record (EHR) prompts to check readiness to quit smoking within 30 days, advise cessation, and connect patients using tobacco quit line e-referral orders. Our objective was to use EHR data to examine the primary outcome of tobacco quit line referrals using pre/post design. RESULTS: Across 54,090 pre- and post-protocol rheumatology clinic visits, 4,601 were with current smokers. We compared outcomes between 4,078 eligible pre-implementation visits and 523 intervention period visits. Post-implementation, the odds of tobacco quit line referral were 26-fold higher compared to our pre-implementation rate (unadjusted odds ratio [OR] 26 [95% confidence interval (95% CI) 6-106]). Adjusted odds of checking readiness to quit in the next 30 days increased over 100-fold compared to pre-implementation (adjusted OR 132 [95% CI 99-177]). Intervention led to e-referrals for 71% of quit-ready patients in <90 seconds; 24% of referred patients reported a quit attempt. CONCLUSION: Implementing Quit Connect in rheumatology clinics was feasible and improved referrals to a state-run tobacco quit line. Given the importance of smoking cessation to reduce cardiopulmonary and rheumatic disease risk, future studies should investigate disseminating cessation protocols like Quit Connect that leverage tobacco quit lines.

Impact of a problem-oriented view on clinical data retrieval.

OBJECTIVE: The electronic health record (EHR) data deluge makes data retrieval more difficult, escalating cognitive load and exacerbating clinician burnout. New auto-summarization techniques are needed. The study goal was to determine if problem-oriented view (POV) auto-summaries improve data retrieval workflows. We hypothesized that POV users would perform tasks faster, make fewer errors, be more satisfied with EHR use, and experience less cognitive load as compared with users of the standard view (SV). METHODS: Simple data retrieval tasks were performed in an EHR simulation environment. A randomized block design was used. In the control group (SV), subjects retrieved lab results and medications by navigating to corresponding sections of the electronic record. In the intervention group (POV), subjects clicked on the name of the problem and immediately saw lab results and medications relevant to that problem. RESULTS: With POV, mean completion time was faster (173 seconds for POV vs 205 seconds for SV; P < .0001), the error rate was lower (3.4% for POV vs 7.7% for SV; P = .0010), user satisfaction was greater (System Usability Scale score 58.5 for POV vs 41.3 for SV; P < .0001), and cognitive task load was less (NASA Task Load Index score 0.72 for POV vs 0.99 for SV; P < .0001). DISCUSSION: The study demonstrates that using a problem-based auto-summary has a positive impact on 4 aspects of EHR data retrieval, including cognitive load. CONCLUSION: EHRs have brought on a data deluge, with increased cognitive load and physician burnout. To mitigate these increases, further development and implementation of auto-summarization functionality and the requisite knowledge base are needed.

Association of Sjögren's Syndrome With Reduced Lifetime Sex Hormone Exposure: A Case-Control Study.

OBJECTIVE: To test whether cumulative estrogen exposure, as determined by age at menarche, age at menopause, female hormone use, hysterectomy, and parity, have an effect on the development of primary Sjögren's syndrome (SS). METHODS: We performed a case-control study of 2,680 women from the Sjögren's International Collaborative Clinical Alliance registry, including 1,320 registrants with primary SS and 1,360 with sicca symptoms but no key features of primary SS (sicca controls). The composite estrogen score (CES) was calculated by point assignment for early menarche (age ≤10 years), high parity (>3 pregnancies), hysterectomy, female hormone use, and late menopause (age ≥53 years). Cumulative menstrual cycling (CMC) was calculated as years menstruating minus time pregnant. RESULTS: Using a regression model that adjusted for age, recruitment site, ethnicity, education, employment status, and smoking, we observed a progressive inverse trend between primary SS and CES. The odds ratio (OR) and 95% confidence interval (95% CI) were as follows for the sicca control group: CES 1, OR 0.81 (95% CI 0.67-0.99); CES 2, OR 0.74 (95% CI 0.57-0.97); CES 3, OR 0.50 (95% CI 0.30-0.86). This trend was corroborated by analysis of CMC. At the highest level of CMC within the postmenopausal group there was a 24% reduction in cumulative sex hormone exposure among primary SS participants relative to controls. CONCLUSION: Women with primary SS have lower estrogen exposure and CMC compared to sicca controls. Increasing estrogen exposure was negatively associated with development of primary SS. Further longitudinal studies of sex hormone exposure in primary SS are needed to confirm these findings.

A Curriculum to Increase Empathy and Reduce Burnout.

PURPOSE: Empathy is essential for good patient care. It underpins effective communication and high-quality, relationship-centered care. Empathy skills have been shown to decline with medical training, concordant with increasing physician distress and burnout. METHODS: We piloted a 6-month curriculum for interns (N = 27) during the 2015-2016 academic year at the University of Wisconsin-Madison. The course included: (1) review of literature on physician well-being and clinical empathy, (2) instruction on the neurobiology of empathy and compassion, (3) explanation of stress physiology and techniques for mitigating its effects, (4) humanities-informed techniques, and (5) introductions to growth mindset and mindful awareness. To measure effectiveness, we compared empathy and burnout scores before and after the course. RESULTS: The course was well-attended. Intern levels of burnout and empathy remained stable over the study period. In multivariable modeling, we found that for each session an intern attended, their emotional exhaustion declined by 3.65 points (P = 0.007), personal accomplishment increased by 2.69 points (P = 0.001), and empathic concern improved by 0.82 points (P = 0.066). The course was well-liked. Learners reported applying course content inside and outside of work and expressed variable preferences for content and teaching methods. CONCLUSION: Skills in empathic and self-care can be taught together to reduce the decline of empathy and well-being that has been seen during internship. In this single-center pilot, resident physicians reported using these skills both inside and outside of work. Our curriculum has the potential to be adopted by other residency programs.

Physician Burnout and Timing of Electronic Health Record Use.

Background: Rates of burnout among physicians have been high in recent years. The Electronic Health Record (EHR) is implicated as a major cause of burnout. Objective: To determine the association between physician burnout and timing of EHR use in an academic internal medicine primary care practice. Methods: We conducted an observational cohort study using cross-sectional and retrospective data. Participants included primary care physicians in an academic outpatient general internal medicine practice. Burnout was measured with a single-item question via self-reported survey. EHR time was measured using retrospective automated data routinely captured within the institution's EHR. EHR time was separated into four categories: weekday workhours in-clinic time, weekday workhours out-of-clinic time, weekday afterhours time, and weekend/holiday afterhours time. Ordinal regression was used to determine the relationship between burnout and EHR time categories. Results: EHR use during in-clinic sessions was related to burnout in both bivariate (OR=1.04, 95% CI 1.01, 1.06; p=0.007) and adjusted (OR=1.07, 95% CI 1.03, 1.1; p=0.001) analyses. No significant relationships were found between burnout and afterhours EHR use. Conclusions: In this small single-institution study, physician burnout was associated with higher levels of in-clinic EHR use but not afterhours EHR use. Improved understanding of the variability of in-clinic EHR use, and the EHR tasks that are particularly burdensome to physicians, could help lead to interventions that better integrate EHR demands with clinical care and potentially reduce burnout. Further studies including more participants from diverse clinical settings are needed to further understand the relationship between burnout and afterhours EHR use.

Soy-Based Infant Formula is Associated with an Increased Prevalence of Comorbidities in Fragile X Syndrome.

A large number of adults and children consume soy in various forms, but little information is available regarding potential neurological side effects. Prior work indicates an association between the consumption of soy-based diets and seizure prevalence in mouse models of neurological disease and in children with autism. Herein, we sought to evaluate potential associations between the consumption of soy-based formula during infancy and disease comorbidities in persons with fragile X syndrome (FXS), while controlling for potentially confounding issues, through a retrospective case-control survey study of participants with FXS enrolled in the Fragile X Online Registry with Accessible Research Database (FORWARD). There was a 25% usage rate of soy-based infant formula in the study population. We found significant associations between the consumption of soy-based infant formula and the comorbidity of autism, gastrointestinal problems (GI) and allergies. Specifically, there was a 1.5-fold higher prevalence of autism, 1.9-fold GI problems and 1.7-fold allergies in participants reporting the use of soy-based infant formula. The major reason for starting soy-based infant formula was GI problems. The average age of seizure and allergy onset occurred long after the use of soy-based infant formula. We conclude that early-life feeding with soy-based infant formula is associated with the development of several disease comorbidities in FXS.

Improved conditional imputation for linear regression with a randomly censored predictor.

This article describes a nonparametric conditional imputation analytic method for randomly censored covariates in linear regression. While some existing methods make assumptions about the distribution of covariates or underestimate standard error due to lack of imputation error, the proposed approach is distribution-free and utilizes resampling to correct for variance underestimation. The performance of the novel method is assessed using simulations, and results are contrasted with methods currently used for a limit of detection censored design, including the complete case approach and other nonparametric approaches. Theoretical justifications for the proposed method are provided, and its application is demonstrated through a study of association between lipoprotein cholesterol in offspring and parental history of cardiovascular disease.

Maternal obesity is not associated with increased crown-rump length in first-trimester ultrasounds of singleton gestations.

OBJECTIVE: To evaluate whether or not obesity affects fetal growth in the first trimester of pregnancy. STUDY DESIGN: A retrospective cohort study of obese versus non-obese women in our ultrasound database was performed to compare crown-rump length (CRL), a surrogate of fetal growth, at the first-trimester genetic screening. RESULTS: A total of 50 obese and 50 non-obese women were included. CRL for both groups was performed at an average of 12wk5d ± 3 d. A linear regression analysis demonstrated that there was no difference between the cohorts in respect to CRL in the first trimester (p = .482). However, the estimated fetal weight at second-trimester anatomy ultrasound and the neonatal birth weight were increased in obese women (p < .001 for both analyses). CONCLUSION: Maternal obesity does not significantly alter the fetal CRL. However, maternal obesity appears to be associated with increased fetal growth as early as the second trimester.

Nutrition and Exercise Strategies to Prevent Excessive Pregnancy Weight Gain: A Meta-analysis.

Objective To evaluate nutrition-only, exercise-only, and nutrition-plus-exercise interventions for optimizing gestational weight gain (GWG) based on the 2009 Institute of Medicine (IOM) guidelines. Study PubMed, Google Scholar, and 2015 Cochrane Review were searched. Analysis of variance was used to determine if significant GWG differences exist between strategies, with additional subanalyses on overweight (OV) or obese women based on 2009 IOM guidelines. Results Of 66 identified studies, 31 contributed data ( n = 8,558). Compared with routine prenatal care, nutrition-only interventions were significantly associated with reduced GWG and are most likely to produce weight gain within IOM recommendations ( p = 0.013). Exercise-only ( p = 0.069) and nutrition-plus-exercise ( p = 0.056) interventions trended toward GWG within IOM guidelines, but did not reach statistical significance. Supervised ( p = 0.61) and unsupervised ( p = 0.494) exercise programs had similar effectiveness. Subanalyses on OV or obese women produced similar results to studies that did not differentiate results based on body mass index: nutrition only ( p = 0.011), exercise only ( p = 0.308), and nutrition plus exercise ( p = 0.129). Conclusion Preventing excessive GWG is crucial, especially for OV or obese women. In the current study, nutrition-based intervention is the health system strategy that showed significant impact on preventing excessive GWG compared with routine prenatal care. Among women who are OV or have obesity, nutrition-only interventions hold the most promise compared with routine prenatal care.
