Utilization of Hepatitis B viremic donors (NAT+) leads to improved kidney transplant access for older adult recipients with little to no wait time.

BACKGROUND: Though the use of Hepatitis B viremic (HBV) donor kidneys may be a safe alternative to improve access to transplantation, there has not been wide acceptance of this practice. In this study, we determined the safety and effectiveness of HBV NAT (+) donor kidneys in a protocolized manner in an older adult population. METHODS: Over a 3-year period, 16 decreased donor kidney transplants were performed with HBV NAT+ kidneys. Recipients of HBV NAT+ kidneys were treated with entecavir started pre-operatively and continued for 52 weeks. RESULTS: HBV NAT+ kidneys were preferentially used in older (68 ± 5 vs. 64 ± 9 years; p = .01) recipients with less dialysis time (93.8% < 5 years vs. 67% <5 years; p = .03). In this cohort, 3/16 had detectable HBV PCR 1-week post-transplant, but all were negative at 9- and 12-months. Calculated estimated glomerular filtration rate (eGFR) was slightly decreased 12-months post-transplant. Post-transplant outcomes in an age-matched cohort showed no difference in rates of delayed graft function, readmission within 30 days, and graft loss or death within 6 months of transplant (p > .05). CONCLUSION: Transplants with HBV NAT+ donor kidneys in a pre-emptive treatment protocol allow for increased safe access to transplantation in older adult recipients with little or no dialysis time.

Oxygen saturation during donor warm ischemia time and outcome of donation after circulatory death (DCD) liver transplantation with static cold storage: A review of 1114 cases.

The donor operation and the hemodynamics during declaration resulting in donor warm ischemia time have been linked to the outcomes in donation after circulatory death (DCD) liver transplantation (LT). Scrutiny of the donor hemodynamics at the time of withdrawal of life support concluded that a functional donor warm ischemia time may be associated with LT graft failure. Unfortunately, the definition for functional donor warm ischemia time has not reached a consensus-but has almost always incorporated time spent in a hypoxic state. Herein, we reviewed 1114 DCD LT cases performed at the 20 highest volume centers during 2014 and 2018. Donor hypoxia began within 3 minutes of withdrawal of life support for 60% of cases and within 10 minutes for 95% of cases. Graft survival was 88.3% at 1 year and 80.3% at 3 years. Scrutinizing the time spent under hypoxic conditions (oxygen saturation ≤ 80%) during the withdrawal of life support, we found an increasing risk of graft failure as hypoxic time increased from 0 to 16 minutes. After 16 minutes and up to 50 minutes, we did not find any increased risk of graft failure. In conclusion, after 16 minutes of time in hypoxia, the risk of graft failure in DCD LT did not increase. The current evidence suggests that an over-reliance on hypoxia time may lead to an unnecessary increase in DCD liver discard and may not be as useful for predicting graft loss after LT.

Reported HIV-related stigma according to race and ethnicity.

People living with HIV/AIDS (PLWHA) have long experienced structural, community, and personal stigma. We explored differences in experienced HIV-related stigma according to race/ethnicity using quantitative and qualitative measures. Sixty-four patients were enrolled in this study (22 White and 42 people of color [POC]). POC scored higher than White PLWHA on all 12 survey statements, with statistically significant differences in disclosure concerns and with one of the statements on public attitudes towards PLWHA. Common themes in the qualitative interview were HIV disclosure concerns and fear of rejection. These data demonstrate that stigma continues to be a significant concern for PLWHA, particularly POC, meaningfully impacting their lives. By acknowledging and working to reduce negative perceptions about PLWHA, physicians may improve care for their patients by developing more trusting relationships.

Importance of internal vaginal pelvic floor muscle exams for women with external lumbar/hip/pelvic girdle pain.

INTRODUCTION AND HYPOTHESIS: The relationship between external lumbar, hip, and/or pelvic girdle pain and internal vaginal pelvic floor myofascial pain is not well described. We assessed this relationship in a cohort of adult women. METHODS: The cohort included women ≥ 18 years old who received care for external lumbar, hip, and/or pelvic girdle pain (reported or elicited on physical examination) who then underwent internal vaginal myofascial levator ani pain assessments, in a tertiary care Female Pelvic Medicine and Reconstructive Surgery pelvic pain clinic over a 2-year period (2013 and 2014). RESULTS: The cohort of 177 women had an average age of 44.9±16.0 years, an average body mass index of 27.2±7.0 kg/m2, and the majority (79.2%) were white. Most patients presented with a chief complaint of pelvic (51.4%), vulvovaginal (18.6%), and/or lumbar (15.3%) pain. Women who reported symptoms of lumbar, hip, or pelvic girdle pain were more likely to have pain on vaginal pelvic floor muscle examination than women without this history (OR, 7.24; 95% CI, 1.95-26.93, p=0.003). The majority (85.9%) of women had bilateral internal vaginal pelvic floor myofascial pain on examination. CONCLUSIONS: Although participants did not describe "vaginal pelvic floor myofascial pain," the high detection rate for internal vaginal pelvic floor myofascial pain on clinical examination highlights an opportunity to improve treatment planning. These findings suggest that the vaginal pelvic floor muscle examination should be part of the assessment of all women with lumbar, hip, and/or pelvic girdle pain. The relationship between this finding and clinical outcomes following directed treatment warrants additional study.

Health literacy in women with chronic pelvic pain.

INTRODUCTION AND HYPOTHESIS: Limited health literacy (HL) is a risk factor for poor patient outcomes, including pain. Chronic pelvic pain (CPP) is a prevalent disorder affecting up to 25% of women and coexists with multiple overlapping conditions. This study aimed to describe health literacy in women with CPP, primarily correlate HL to pain intensity and pain duration, and secondarily correlate HL to mood symptoms and pain catastrophizing. We hypothesized that women with CPP with higher HL would report lower levels of pain intensity and duration. METHODS: This was a prospective, cross-sectional study. Forty-five women with CPP were recruited from outpatient Physical Medicine & Rehabilitation and Female Pelvic Medicine & Reconstructive Surgery clinics. Validated questionnaires were administered to evaluate pain intensity and duration, pain disability, psychological symptoms, pain catastrophizing, and health literacy. Statistical analyses included descriptive statistics of patient characteristics and summary scores, as well as Spearman's rank correlation coefficients (rho) to assess the strength of associations between summary scores and health literacy. RESULTS: Forty-five women with CPP were enrolled with mean age of 49 years, majority non-Hispanic White, and median chronic pelvic pain duration of 7 years. Possible or high likelihood of limited health literacy was identified in 20% women with CPP (11.1% and 8.9%, respectively). Limited health literacy was moderately correlated with pain intensity, depressive symptoms, and pain catastrophizing. Pain duration was not significantly correlated with health literacy. The remaining 80% of women with CPP were likely to have adequate health literacy. CONCLUSIONS: A majority of women with CPP in this single center study were likely to have adequate health literacy. Limited health literacy was seen in a minority of women with CPP but was moderately correlated with greater pain intensity, more depressive symptoms, and higher pain catastrophizing. This study identified that women with CPP were likely to have adequate HL, but underscores the importance of considering HL screening and interventions in those with higher pain intensity, depression, and pain catastrophizing.

It's a Hard Knock Life: How Kids With Mild Traumatic Brain Injuries Are Treated.

OBJECTIVES: The diagnosis and treatment of mild traumatic brain injuries (mTBIs) by emergency medicine providers is greatly varied. Because of the frequency and long-term consequences associated with pediatric head injuries, it is crucial that adequate counseling is provided in acute care settings. The purpose of our study is to evaluate existing practices at Loyola University Medical Center emergency department to address inconsistencies in diagnostic or discharge practices and determine future quality improvement measures. METHODS: A retrospective cohort study was conducted at an academic hospital emergency department of patient records from 2017 to 2020. Demographic, diagnostic, and discharge data were summarized, and Pearson χ2 tests and Fisher exact tests were performed to determine associations among patient characteristics and provider practices. RESULTS: A total of 1160 patients met inclusion criteria for analysis. In terms of diagnostic procedure, 31.6% of providers did not uniformly use existing screening criteria, such as PECARN, to determine if CT scans were needed for mTBI evaluation. Most discharge instructions were based on a generalized template on epic (91.9%). Only a minority of providers prepared patient-specific instructions through written, verbal, or other supplemental materials. The most common formats included epic only (46.1%), epic and personalized written instructions (20.2%), and epic and verbal instructions (12.4%). Follow-up care instructions were provided to 93% of patients who received discharged instructions, mainly for primary care (96.7%), sports medicine (1.58%), neurology (0.65%), or other providers (1.11%). CONCLUSIONS: There is a lack of consistency in the evaluation and education of mTBI in pediatric patients. There is a need for personalized discharge instructions to ensure adequate patient and parent understanding and compliance. Further studies looking at long-term outcomes in these patients would also be beneficial.

Internal and External Validation of an Alcohol Biomarker for Screening in Trauma.

OBJECTIVE: We aimed to examine biomarkers for screening unhealthy alcohol use in the trauma setting. SUMMARY AND BACKGROUND DATA: Self-report tools are the practice standard for screening unhealthy alcohol use; however, their collection suffers from recall bias and incomplete collection by staff. METHODS: We performed a multi-center prospective clinical study of 251 adult patients who arrived within 24 hours of injury with external validation in another 60 patients. The Alcohol Use Disorders Identification Test served as the reference standard. The following biomarkers were measured: (1) PEth; (2) ethyl glucuronide; (3) ethyl sulfate; (4) gamma-glutamyl-transpeptidase; (5) carbohydrate deficient transferrin; and (6) blood alcohol concentration (BAC). Candidate single biomarkers and multivariable models were compared by considering discrimination (AUROC). The optimal cutpoint for the final model was identified using a criterion for setting the minimum value for specificity at 80% and maximizing sensitivity. Decision curve analysis was applied to compare to existing screening with BAC. RESULTS: PEth alone had an AUROC of 0.93 [95% confidence interval (CI): 0.92-0.93] in internal validation with an optimal cutpoint of 25 ng/mL. A 4- variable biomarker model and the addition of any single biomarker to PEth did not improve AUROC over PEth alone ( P > 0.05). Decision curve analysis showed better performance of PEth over BAC across most predicted probability thresholds. In external validation, sensitivity and specificity were 76.0% (95% CI: 53.0%-92.0%) and 73.0% (95% CI: 56.0%-86.0%), respectively.Conclusion and Relevance: PEth alone proved to be the single best biomarker for screening of unhealthy alcohol use and performed better than existing screening systems with BAC. PEth may overcome existing screening barriers.

Pilot Study of a Self-Administered Hypnosis Intervention for Functional Dyspepsia.

BACKGROUND: Functional dyspepsia (FD) is a chronic disorder of the upper gastrointestinal tract that currently lacks substantially effective therapy options. AIMS: To evaluate the feasibility and potential impact on FD symptoms and well-being of a fully automated gut-directed hypnosis intervention delivered via audio recordings. METHODS: FD patients were enrolled at a single medical center and given access to a password-protected website where they completed 7 bi-weekly audio-recorded hypnosis sessions over a 3-month period. Study questionnaires including the Patient assessment of upper gastrointestinal symptom severity index, Short-Form Nepean Dyspepsia Index, the Visceral Sensitivity Index, and the Brief Symptom Inventory (BSI-18) were completed online pre-treatment, mid-treatment, post-treatment and at 3-month follow-up. RESULTS: Of 23 enrolled patients (18 females; mean age = 38 years), 96% completed the entire treatment program and 3-month follow-up. Intention-to-treat analyses showed significant improvement at both end of treatment and 3-month follow-up in dyspepsia severity and quality of life, as well as in gut-specific anxiety and psychological distress. 68% of treatment completers reported that their FD symptoms were improved. Improvement in FD severity was significantly positively correlated with baseline PAGI-SYM total scores and BSI Global Severity Index scores. CONCLUSIONS: The fully automated hypnosis audio treatment program, which requires no therapist or clinician involvement, demonstrated excellent feasibility and resulted in significant improvement in FD symptoms, quality of life and emotional well-being. The results indicate that the intervention has high potential as adjunctive therapy for FD and warrants further investigation in a randomized controlled trial.

Acupuncture for female bladder pain syndrome: a randomized controlled trial.

INTRODUCTION: Growing evidence supports acupuncture for several pain conditions including chronic prostatitis. This study aimed to determine the safety, tolerability, and effectiveness of acupuncture in reducing pain in women with interstitial cystitis/bladder pain syndrome (IC/BPS). MATERIALS AND METHODS: This prospective randomized single-blinded study compared electro-acupuncture (EA) to minimal acupuncture (MA) after 6 weekly treatments and again after 6 weeks of no treatment. Pain was assessed using the Brief Pain Inventory-Short Form (worst pain, average pain, pain severity, pain interference) and the Pain Catastrophizing Scale (PCS). Physical exams evaluated pelvic floor muscle tenderness. Mixed-effects models were used to estimate adjusted means over follow up. RESULTS: Patients were randomized to EA (n = 11) or MA (n = 10). There were no adverse events. Both groups' worst pain improved at 6 weeks, -2.91 ± 0.59 and -2.09 ± 0.68 for EA and MA respectively with no difference between groups (p = 0.37). Results were similar at 12 weeks. The EA group had greater improvement in pain interference at 6 weeks, -3.28 ± 0.51 versus -1.67 ± 0.58 (p = 0.049). The between group difference was not maintained at 12 weeks (p = 0.13). Average pain and pain severity showed no difference between groups (p > 0.05). The PCS improved overall at 6 weeks, -6.2 ± 2.5 (p = 0.03), with no difference between groups (p = 0.39). On physical exam, only the EA group showed a significant decrease in levator ani tenderness (p = 0.031) after treatment. CONCLUSIONS: Both EA and MA showed improvement in worst pain scores, however EA showed greater improvement in pain interference and pelvic floor muscle tenderness in women with IC/BPS.

Effectiveness of an interprofessional ambulatory care model on diabetes: evaluating clinical markers in a low-income patient population.

The purpose of this study was to determine whether a new ambulatory care model, interprofessional collaborative care-coordinated team model (interprofessional model), based on the Wagner Care Model improved clinical indicators in a low-income population. This study was a retrospective 12-month pre-post (n = 204) and propensity matched (n = 171) comparative study of the interprofessional model in a primary clinic for patients with type 2 diabetes. Secondary data were collected from June 2014to February 2017 in an academic medical centre in a large Midwestern city. Findings demonstrated statistically and clinically significant improvement in A1C in both the pre/post arm of the study (↓ 0.8%) and the intervention/propensity matched arm (↓ 0.53%). Within the intervention group, there was a significant decrease in weight in the pre/post arm with 55% of cases losing weight, whereas 45% did not lose weight (p = .02). Diastolic blood pressure less than 90 also significantly improved in the pre/post arm of the study (10.1% n = 18, versus 3.9%, n = 7, p = .04). The interprofessional model showed that an ambulatory healthcare redesign incorporating an interprofessional team approach to optimise the health of this type 2 diabetes patient population can be effective. This study demonstrates the importance of using interprofessional collaborative practice teams to guide healthcare and improve patient outcomes.

Myosteatosis at diagnosis is adversely associated with 2-year survival in women with estrogen receptor-negative metastatic breast cancer.

PURPOSE: To examine the relationship between skeletal muscle (SM) and cancer-specific outcomes for women with estrogen receptor-negative (ER-) metastatic breast cancer (MBC). METHODS: For this retrospective cohort, females (≥ 18 years) with histologically confirmed ER- MBC and computerized tomography (CT) imaging were screened. Demographic, anthropometric, and clinical data were collected uniformly from the electronic medical record. CT images inclusive of the third lumbar region (L3) at diagnosis, 6 and 12 months, were used to classify sarcopenia (≤ 41 cm2/m2) and myosteatosis (< 41 or 33 Hounsfield Units, adjusted for body mass index (BMI)) and to evaluate changes in SM and total adipose tissue (TAT) over time. Kaplan-Meier curves, Cox Proportional Hazards (PH), and restricted mean survival time (RMST) estimates were generated to examine the relationship between sarcopenia and myosteatosis and time to tumor progression (TTP), treatment toxicity and 2-year survival, adjusting for covariates. RESULTS: Participants were 58.0 (15.0) years of age, ethnically diverse (55% non-Hispanic white, 31% Black, 11% Hispanic), post-menopausal (73%, n = 111), and classified as overweight (BMI 29.4 (7.6)). At diagnosis, 40% (n = 61) were sarcopenic, 49% had myosteatosis, and 28% (n = 42) had both. While Cox PH modeling and RMST analysis reveal no significant relationship between sarcopenia at diagnosis and 2-year survival (RMST difference - 1.6 (1.4) months, HR 1.35 (0.88-2.08)), these analyses support a significant, adverse association between myosteatosis at diagnosis and 2-year survival (RMST difference - 2.4 (1.5) months, HR 1.72 (1.09-2.72)). Incident sarcopenia was 11% (n = 5/45) and 2.5% (n = 1/40), respectively, while incident myosteatosis was 19% (n = 8/42) and 15% (n = 5/34) at 6 and 12 months, respectively. TTP and treatment toxicities did not appear to be related to diagnostic SM or body composition changes over time. CONCLUSION: Targeted interventions initiated within the first year of diagnosis to preserve or improve SM quality seem warranted for women with ER-MBC.

Childhood Daily Energy Expenditure Does Not Decrease with Market Integration and Is Not Related to Adiposity in Amazonia.

BACKGROUND: Childhood overweight and obesity (OW/OB) is increasingly centered in low- and middle-income countries (LMICs) as rural populations experience market integration and lifeway change. Most explanatory studies have relied on imprecise estimates of children's energy expenditure, restricting understanding of the relative effects of changes in diet and energy expenditure on the development of OW/OB in transitioning contexts. OBJECTIVES: This study used gold-standard measurements of children's energy expenditure to investigate the changes that underlie OW/OB and the nutrition/epidemiologic transition. METHODS: Cross-sectional data were collected from "rural" (n = 43) Shuar forager-horticulturalist children and their "peri-urban" (n = 34) Shuar counterparts (age 4-12 y) in Amazonian Ecuador. Doubly labeled water measurements of total energy expenditure (TEE; kcal/d), respirometry measurements of resting energy expenditure (REE; kcal/d), and measures of diet, physical activity, immune activity, and market integration were analyzed primarily using regression models. RESULTS: Peri-urban children had higher body fat percentage (+8.1%, P < 0.001), greater consumption of market-acquired foods (multiple P < 0.001), lower concentrations of immune activity biomarkers (multiple P < 0.05), and lower REE (-108 kcal/d, P = 0.002) than rural children. Despite these differences, peri-urban children's TEE was indistinguishable from that of rural children (P = 0.499). Moreover, although sample-wide IgG concentrations and household incomes predicted REE (both P < 0.05), no examined household, immune activity, or physical activity measures were related to children's overall TEE (all P > 0.09). Diet and energy expenditure associations with adiposity demonstrate that only reported consumption of market-acquired "protein" and "carbohydrate" foods predicted children's body fat levels (multiple P < 0.05). CONCLUSIONS: Despite underlying patterns in REE, Shuar children's TEE is not reliably related to market integration and-unlike dietary measures-does not predict adiposity. These findings suggest a leading role of changing dietary intake in transitions to OW/OB in LMICs.

Impact of donor smoking history on post heart transplant outcomes: A propensity-matched analysis of ISHLT registry.

PURPOSE: Smoking is a major public health issue, and its effect on cardiovascular outcomes is well established. This study evaluates the impact of donor smoking on heart transplant (HT) outcomes. METHODS: HT recipients between January 1, 2005, and December 31, 2016, with known donor smoking status were queried from the International Society of Heart and Lung Transplantation (ISHLT) registry. The primary outcome was all-cause mortality, and secondary endpoints were graft failure, acute rejection, and cardiac allograft vasculopathy. We utilized propensity-score matching to identify cohorts of recipients with and without a history of donor smoking. Hazard ratios for post-transplant outcomes for the matched sample were estimated from separate Cox proportional hazard models. RESULTS: Of 26 390 patients in the cohort, 18.9% had history of donor smoking. Donors with history of smoking were older, predominantly male and had higher incidence of diabetes, hypertension, cocaine use, and "high-risk" status. In propensity-matched analysis, recipients with a history of donor smoking had increased risk of death (HR 1.11, 95% CI 1.03-1.20) and higher risk of graft failure (HR 1.11, 95% CI 1.03-1.20). CONCLUSION: Donor smoking was associated with increased mortality and higher incidence of graft failure following HT. Consideration of donor smoking history is warranted while evaluating donor hearts.

Urinary retention is rare after colpocleisis and concomitant midurethral sling: a 10-year experience.

OBJECTIVES: The optimal method of managing stress urinary incontinence (SUI) in women undergoing colpocleisis remains unclear, especially in a setting of urinary retention. We aim to compare postoperative retention after colpocleisis with or without concomitant midurethral sling (MUS). METHODS: A retrospective chart review of all women who underwent colpocleisis with or without MUS from October 2007 to October 2017 was performed. Women with preoperative and 2-week postoperative post-void residual volume (PVR) measurements were included. Urinary retention was defined as PVR of ≥100 ml. Analysis included t tests/Wilcoxon rank, Chi-squared/Fisher's exact, and multivariate linear regression models. RESULTS: A total of 231 women with a mean age of 77.7 years (± 6.0 years SD) met the inclusion criteria. One hundred and thirty-eight women underwent colpocleisis alone, whereas 93 women had colpocleisis with MUS. Preoperative retention rates were high (44.9% vs 34.4%, for colpocleisis alone versus with MUS, p = 0.114). Postoperative retention rates were lower and similar between the groups (10.1% vs 11.8%, for colpocleisis alone vs with MUS, p = 0.69). Linear regression models showed the adjusted odds ratio for postoperative urinary retention in patients with concomitant MUS was 1.68 (95% confidence interval: 0.64-4.41) compared with patients with colpocleisis alone and this did not reach statistical significance (p = 0.292). Fortunately, after colpocleisis, women had high rates of resolution of retention, regardless of MUS (80.3% vs 90.6% for colpocleisis alone vs with MUS; p = 0.20). Few women required reoperation for retention (3.1%). CONCLUSIONS: Placement of an MUS at the time of colpocleisis is a safe and effective therapy. This appears to be unaffected by preoperative urinary retention status.

Communicating Spiritual Care in the Electronic Health Record.

Chaplains must document their ministry of care in electronic health records that primarily focus on the physical dimension of care. Creating chaplain documentation that reflects the spiritual dimension of care requires chaplains to participate in the screen design. This article describes how chaplain documentation was designed and refined using psychometric methods. The resulting system successfully supported chaplain workflow, provided an ability to aggregate chaplain workload, and integrated the chaplain into the interprofessional team by structuring, linking, and sharing both the chaplain and nursing assessment of spiritual distress in the electronic health record. Documentation used 5-point Likert scales to measure different dimensions of patient spirituality. Reliability and validity were further evaluated as part of a workshop at an Association of Professional Chaplains annual meeting. Findings supported interrater reliability and the ability to predict and discriminate change pre and post encounter. Documentation screen content is presented.

Trends, Cost, and Mortality From Sepsis After Trauma in the United States: An Evaluation of the National Inpatient Sample of Hospitalizations, 2012-2016.

OBJECTIVES: Identification and outcomes in patients with sepsis have improved over the years, but little data are available in patients with trauma who develop sepsis. We aimed to examine the cost and epidemiology of sepsis in patients hospitalized after trauma. DESIGN: Retrospective cohort study. PATIENTS: National Inpatient Sample. INTERVENTIONS: Sepsis was identified between 2012 and 2016 using implicit and explicit International Classification of Diseases, Ninth and Tenth Revision codes. Analyses were stratified by injury severity score greater than or equal to 15. Annual trends were modeled using generalized linear models. Survey-adjusted logistic regression was used to compare the odds for in-hospital mortality, and the average marginal effects were calculated to compare the cost of hospitalization with and without sepsis. MEASUREMENTS AND MAIN RESULTS: There were 320,450 (SE = 3,642) traumatic injury discharges from U.S. hospitals with sepsis between 2012 and 2016, representing 6.0% (95% CI, 5.9-6.0%) of the total trauma population (n = 5,329,714; SE = 47,447). In-hospital mortality associated with sepsis after trauma did not change over the study period (p > 0.40). In adjusted analysis, severe (injury severity score ≥ 15) and nonsevere injured septic patients had an odds ratio of 1.39 (95% CI, 1.31-1.47) and 4.32 (95% CI, 4.06-4.59) for in-hospital mortality, respectively. The adjusted marginal cost for sepsis compared with nonsepsis was $16,646 (95% CI, $16,294-$16,997), and it was greater than the marginal cost for severe injury compared with nonsevere injury $8,851 (95% CI, $8,366-$8,796). CONCLUSIONS: While national trends for sepsis mortality have improved over the years, our analysis of National Inpatient Sample did not support this trend in the trauma population. The odds risk for death after sepsis and the cost of care remained high regardless of severity of injury. More rigor is needed in tracking sepsis after trauma and evaluating the effectiveness of hospital mandates and policies to improve sepsis care in patients after trauma.

Focal Adhesion Kinase and ß-Catenin Cooperate to Induce Hepatocellular Carcinoma.

There is an urgent need to understand the molecular signaling pathways that drive or mediate the development of hepatocellular carcinoma (HCC). The focal adhesion kinase (FAK) gene protein tyrosine kinase 2 is amplified in 16.4% of The Cancer Genome Atlas HCC specimens, and its amplification leads to increased FAK mRNA expression. It is not known whether the overexpression of FAK alone is sufficient to induce HCC or whether it must cooperate in some ways with other oncogenes. In this study, we found that 34.8% of human HCC samples with FAK amplification also show ß-catenin mutations, suggesting a co-occurrence of FAK overexpression and ß-catenin mutations in HCC. We overexpressed FAK alone, constitutively active forms of ß-catenin (CAT) alone, or a combination of FAK and CAT in the livers of C57/BL6 mice. We found that overexpression of both FAK and CAT, but neither FAK nor CAT alone, in mouse livers was sufficient to lead to tumorigenesis. We further demonstrated that FAK's kinase activity is required for FAK/CAT-induced tumorigenesis. Furthermore, we performed RNA-sequencing analysis to identify the genes/signaling pathways regulated by FAK, CAT, or FAK/CAT. We found that FAK overexpression dramatically enhances binding of ß-catenin to the promoter of androgen receptor (AR), which leads to increased expression of AR in mouse livers. Moreover, ASC-J9, an AR degradation enhancer, suppressed FAK/CAT-induced HCC formation. Conclusion: FAK overexpression and ß-catenin mutations often co-occur in human HCC tissues. Co-overexpression of FAK and CAT leads to HCC formation in mice through increased expression of AR; this mouse model may be useful for further studies of the molecular mechanisms in the pathogenesis of HCC and could lead to the identification of therapeutic targets.

Brigham Eyebrow Tool for Alopecia: A Reliable Assessment of Eyebrow Alopecia Areata.

There are no tools to evaluate eyebrow involvement in patients with alopecia areata. We developed and assessed the reliability of the Brigham Eyebrow Tool for Alopecia (BETA) as a quantitative evaluation of eyebrow alopecia areata. BETA uses facial landmarks of eyebrow anatomy and is calculated using surface area and density. A total of 50 eyebrow images with varying levels of hair loss were distributed to six board-certified dermatologists at three academic medical centers with standardized instructions and examples. Interrater and intrarater reliability were calculated using intraclass correlation coefficients (ICCs). BETA demonstrated high interrater (ICC = 0.88, confidence interval = 0.83-0.92 right eyebrow scores and ICC = 0.90, confidence interval = 0.85-0.94 left eyebrow scores) and intrarater (ICC = 0.90, confidence interval = 0.85-0.93 right eyebrow scores and ICC = 0.91, confidence interval = 0.87-0.94 left eyebrow scores) reliability. When measured in the same patient with varying degrees of hair loss over time, BETA demonstrated sensitivity to change. BETA is a simple and reliable objective assessment of eyebrow alopecia areata. BETA is easy-to-use and quick to calculate, making it feasible for a variety of clinical and research settings. Although developed for alopecia areata, we hope that BETA will be investigated in other etiologies of eyebrow alopecia to serve as a universal tool for monitoring disease progression, improvement, and response to treatment.

Vaginal estrogen therapy is associated with increased Lactobacillus in the urine of postmenopausal women with overactive bladder symptoms.

BACKGROUND: Previous work has shown that the vaginal microbiome decreases in Lactobacillus predominance and becomes more diverse after menopause. It has also been shown that estrogen therapy restores Lactobacillus dominance in the vagina and that topical estrogen is associated with overactive bladder symptom improvement. We now know that the bladder contains a unique microbiome and that increased bladder microbiome diversity is associated with overactive bladder. However, there is no understanding of how quickly each pelvic floor microbiome responds to estrogen or if those changes are associated with symptom improvement. OBJECTIVE: This study aimed to determine if estrogen treatment of postmenopausal women with overactive bladder decreases urobiome diversity. STUDY DESIGN: We analyzed data from postmenopausal participants in 2 trials (NCT02524769 and NCT02835846) who chose vaginal estrogen as the primary overactive bladder treatment and used 0.5 g of conjugated estrogen (Premarin cream; Pfizer, New York City, NY) twice weekly for 12 weeks. Baseline and 12-week follow-up data included the Overactive Bladder questionnaire, and participants provided urine samples via catheter, vaginal swabs, perineal swabs, and voided urine samples. Microbes were detected by an enhanced culture protocol. Linear mixed models were used to estimate microbiome changes over time. Urinary antimicrobial peptide activity was assessed by a bacterial growth inhibition assay and correlated with relative abundance of members of the urobiome. RESULTS: In this study, 12 weeks of estrogen treatment resulted in decreased microbial diversity within the vagina (Shannon, P=.047; Richness, P=.043) but not in the other niches. A significant increase in Lactobacillus was detected in the bladder (P=.037) but not in the vagina (P=.33), perineum (P=.56), or voided urine (P=.28). The change in Lactobacillus levels in the bladder was associated with modest changes in urgency incontinence symptoms (P=.02). The relative abundance of the genus Corynebacterium correlated positively with urinary antimicrobial peptide activity after estrogen treatment. CONCLUSION: Estrogen therapy may change the microbiome of different pelvic floor niches. The vagina begins to decrease in diversity, and the bladder experiences a significant increase in Lactobacillus levels; the latter is correlated with a modest improvement in the symptom severity subscale of the Overactive Bladder questionnaire.

Publicly available machine learning models for identifying opioid misuse from the clinical notes of hospitalized patients.

BACKGROUND: Automated de-identification methods for removing protected health information (PHI) from the source notes of the electronic health record (EHR) rely on building systems to recognize mentions of PHI in text, but they remain inadequate at ensuring perfect PHI removal. As an alternative to relying on de-identification systems, we propose the following solutions: (1) Mapping the corpus of documents to standardized medical vocabulary (concept unique identifier [CUI] codes mapped from the Unified Medical Language System) thus eliminating PHI as inputs to a machine learning model; and (2) training character-based machine learning models that obviate the need for a dictionary containing input words/n-grams. We aim to test the performance of models with and without PHI in a use-case for an opioid misuse classifier. METHODS: An observational cohort sampled from adult hospital inpatient encounters at a health system between 2007 and 2017. A case-control stratified sampling (n = 1000) was performed to build an annotated dataset for a reference standard of cases and non-cases of opioid misuse. Models for training and testing included CUI codes, character-based, and n-gram features. Models applied were machine learning with neural network and logistic regression as well as expert consensus with a rule-based model for opioid misuse. The area under the receiver operating characteristic curves (AUROC) were compared between models for discrimination. The Hosmer-Lemeshow test and visual plots measured model fit and calibration. RESULTS: Machine learning models with CUI codes performed similarly to n-gram models with PHI. The top performing models with AUROCs > 0.90 included CUI codes as inputs to a convolutional neural network, max pooling network, and logistic regression model. The top calibrated models with the best model fit were the CUI-based convolutional neural network and max pooling network. The top weighted CUI codes in logistic regression has the related terms 'Heroin' and 'Victim of abuse'. CONCLUSIONS: We demonstrate good test characteristics for an opioid misuse computable phenotype that is void of any PHI and performs similarly to models that use PHI. Herein we share a PHI-free, trained opioid misuse classifier for other researchers and health systems to use and benchmark to overcome privacy and security concerns.
