ABSTRACT

BACKGROUND AND OBJECTIVES: Many heterogenous orthotopic liver transplant (OLT) protocols exist for patients with unresectable cholangiocarcinoma. Little is known about the incidence, predictors for, and the significance of achieving a pathologic complete response (pCR). METHODS: We performed a systematic review through September 2022 of the PubMed, Embase, and Web of Science databases. A random-effect meta-analysis was conducted to pool data across studies with reported pCR rates. Heterogeneity between treatment protocols was assessed via subgroup analysis. The pCR and 1-, 3-, and 5-year recurrence-free survival (RFS) and overall survival (OS) rates were extracted as outcomes of interest. RESULTS: A total of 15 studies reported pCR rates and were grouped by use of the Mayo protocol (4/15), stereotactic body radiation therapy (2/15), and an Other category (9/15). The pooled pCR rate among all studies was 32%. Both radiation technique and duration of CHT showed no significant association with pCR (p = 0.05 and 0.13, respectively). Pooled 1-year RFS and OS after any neoadjuvant therapy and OLT was 80% (95% confidence interval [CI], 0.61-0.91), and 91% (95% CI, 0.87-0.94), respectively. There was no 1-year OS difference detected among the three groups. pCR was not associated with OS in the meta-regression. Pooled 3- and 5-year OS among all studies was 72% and 61%, respectively. CONCLUSIONS: The pooled incidence of pCR was 32%. Differences in radiation technique did not appear to influence pCR rates and upon meta-regression, pCR was not a surrogate marker for survival.

ABSTRACT

Clinical outcomes of repetitive transcranial magnetic stimulation (rTMS) for treatment of treatment-resistant depression (TRD) vary widely and there is no mood rating scale that is standard for assessing rTMS outcome. It remains unclear whether TMS is as efficacious in older adults with late-life depression (LLD) compared to younger adults with major depressive disorder (MDD). This study examined the effect of age on outcomes of rTMS treatment of adults with TRD. Self-report and observer mood ratings were measured weekly in 687 subjects ages 16-100 years undergoing rTMS treatment using the Inventory of Depressive Symptomatology 30-item Self-Report (IDS-SR), Patient Health Questionnaire 9-item (PHQ), Profile of Mood States 30-item, and Hamilton Depression Rating Scale 17-item (HDRS). All rating scales detected significant improvement with treatment; response and remission rates varied by scale but not by age (response/remission ≥ 60: 38%-57%/25%-33%; <60: 32%-49%/18%-25%). Proportional hazards models showed early improvement predicted later improvement across ages, though early improvements in PHQ and HDRS were more predictive of remission in those < 60 years (relative to those ≥ 60) and greater baseline IDS burden was more predictive of non-remission in those ≥ 60 years (relative to those < 60). These results indicate there is no significant effect of age on treatment outcomes in rTMS for TRD, though rating instruments may differ in assessment of symptom burden between younger and older adults during treatment.

ABSTRACT

BACKGROUND: Patients with myofascial pelvic floor dysfunction often present with lower urinary tract symptoms, such as urinary frequency, urgency, and bladder pressure. Often confused with other lower urinary tract disorders, this constellation of symptoms, recently termed myofascial urinary frequency syndrome, is distinct from other lower urinary tract symptoms and optimally responds to pelvic floor physical therapy. A detailed pelvic floor myofascial examination performed by a skilled provider is currently the only method to identify myofascial urinary frequency syndrome. Despite a high influence on quality of life, low awareness of this condition combined with no objective diagnostic testing leads to the frequent misdiagnosis or underdiagnosis of myofascial urinary frequency syndrome. OBJECTIVE: This study aimed to develop a screening measure to identify patients with myofascial urinary frequency syndrome (bothersome lower urinary tract symptoms secondary to myofascial pelvic floor dysfunction) from patient-reported symptoms. STUDY DESIGN: A population of patients with isolated myofascial urinary frequency syndrome was identified by provider diagnosis from a tertiary urology practice and verified by standardized pelvic floor myofascial examination and perineal surface pelvic floor electromyography. Least Angle Shrinkage and Selection Operator was used to identify candidate features from the Overactive Bladder Questionnaire, Female Genitourinary Pain Index, and Pelvic Floor Distress Index predictive of myofascial urinary frequency syndrome in a pooled population also containing subjects with overactive bladder (n=42), interstitial cystitis/bladder pain syndrome (n=51), and asymptomatic controls (n=54) (derivation cohort). A simple, summated score of the most discriminatory questions using the original scaling of the Pelvic Floor Distress Index 5 (0-4) and Genitourinary Pain Index 5 (0-5) and modified scaling of Female Genitourinary Pain Index 2b (0-3) had an area under the curve of 0.75. As myofascial urinary frequency syndrome was more prevalent in younger subjects, the inclusion of an age penalty (3 points added if under the age of 50 years) improved the area under the curve to 0.8. This score was defined as the Persistency Index (possible score of 0-15). The Youden Index was used to identify the optimal cut point Persistency Index score for maximizing sensitivity and specificity. RESULTS: Using a development cohort of 215 subjects, the severity (Pelvic Floor Distress Index 5) and persistent nature (Female Genitourinary Pain Index 5) of the sensation of incomplete bladder emptying and dyspareunia (Female Genitourinary Pain Index 2b) were the most discriminatory characteristics of the myofascial urinary frequency syndrome group, which were combined with age to create the Persistency Index. The Persistency Index performed well in a validation cohort of 719 patients with various lower urinary tract symptoms, including overactive bladder (n=285), interstitial cystitis/bladder pain syndrome (n=53), myofascial urinary frequency syndrome (n=111), controls (n=209), and unknown diagnoses (n=61), exhibiting an area under the curve of 0.74. A Persistency Index score ≥7 accurately identified patients with myofascial urinary frequency syndrome from an unselected population of individuals with lower urinary tract symptoms with 80% sensitivity and 61% specificity. A combination of the Persistency Index with the previously defined Bladder Pain Composite Index and Urge Incontinence Composite Index separated a population of women seeking care for lower urinary tract symptoms into groups consistent with overactive bladder, interstitial cystitis/bladder pain syndrome, and myofascial urinary frequency syndrome phenotypes with an overall diagnostic accuracy of 82%. CONCLUSION: Our study recommends a novel screening method for patients presenting with lower urinary tract symptoms to identify patients with myofascial urinary frequency syndrome. As telemedicine becomes more common, this index provides a way of screening for myofascial urinary frequency syndrome and initiating pelvic floor physical therapy even before a confirmatory pelvic examination.

ABSTRACT

BACKGROUND: Hepatic encephalopathy (HE) is a major cause of mortality and morbidity in patients with cirrhosis. Lactulose non-adherence is one of the most frequently reported precipitants of hospital admission for HE. AIMS: We aimed to identify which factors contribute most to lactulose non-adherence and propose strategies to promote greater adherence and utilization of lactulose. METHODS: Participants in this study consisted of patients with cirrhosis who were taking lactulose for prevention of HE. Subjects were administered the Morisky Adherence Scale 8 (MAS-8) and a customized 16-question survey that assessed barriers to lactulose adherence. Results from the MAS-8 were used to stratify subjects into "adherent" and "non-adherent" groups. Survey responses were compared between groups. RESULTS: We enrolled 129 patients in our study, of whom 45 were categorized as "adherent and 72 were categorized as "non-adherent." Barriers to adherence included large volumes of lactulose, high frequency of dosing, difficulty remembering to take the medication, unpleasant taste, and medication side-effects. Most patients (97%) expressed understanding of the importance of lactulose, and 71% of patients felt that lactulose was working to manage their HE. Hospital admission rates for HE was higher in non-adherent patients, although this difference was not statistically significant. CONCLUSION: We identified several factors that contribute to lactulose non-adherence among patients treated for HE. Many of these factors are potentially modifiable. Patient and care-giver education are critical to assure adherence. Pharmacists and nurses are an essential but underutilized aspect of education regarding proper medication use.

ABSTRACT

INTRODUCTION: We sought to determine rates of pelvic organ prolapse (POP) recurrence following pregnancy and delivery in reproductive-age women with prior hysteropexy. METHODS: Scopus, MEDLine, EMBASE, Cochrane Library, and ClinicalTrials.gov databases were searched from inception to May 2020 for combinations of any of the keywords: "pregnancy", "delivery", "fertility", or "cesarean" with a comprehensive list of uterine-sparing surgical procedures for POP repair. Using approach, 1,817 articles were identified describing surgical, uterine-sparing POP repair techniques and subsequent pregnancy and delivery outcomes in reproductive-age women.   RESULTS: Twenty-seven studies describing 218 pregnancies, including 215 deliveries and 3 abortions, were summarized using narrative review and descriptive statistics. Successful pregnancies were reported following a diverse range of uterine-sparing prolapse repairs, both native tissue and mesh-augmented, that utilized vaginal, open abdominal, and laparoscopic approaches. We observed shifts from native tissue repairs to mesh-augmented laparoscopic repairs over time. POP recurrence occurred in 12% of subjects overall, 15% after vaginal and 10% after abdominal prolapse repairs. While meta-analysis identified higher recurrence rates after vaginal delivery (15%) than cesarean section (10%), due to small study numbers, multiple confounders, and heterogeneity between studies, no significant differences in recurrence rates could be identified between vaginal and abdominal surgical approaches, utilization of mesh augmentation, or mode of delivery. CONCLUSION: Although literature on pregnancy following uterine-sparing POP repair is limited, available data suggest that prolapse recurrence after pregnancy and delivery remains similar to that after prolapse repair without subsequent pregnancies with few documented perinatal complications.

ABSTRACT

PURPOSE: This study aims to characterize the physiologic response of both eyelid and eyebrow position to increasing downward forces simulated by external weights. METHODS: In this prospective observational study, both normal individuals and patients affected by ptosis were tested. External eyelid weights were placed on one upper eyelid with incrementally increasing weight from 0.2 to 2.4 g. The eyelid carrying the weight was randomly selected for normal subjects and patients with bilateral ptosis, whereas for unilateral ptosis, the ptotic eyelid was utilized. Photographs were obtained at baseline and with increasing weight until MRD1 reached 0 on the weighted side or, until 2.4 g was reached. Eyelid and brow position on the weighted and unweighted sides were digitally measured in millimeter. Primary outcome measures were change in the margin to reflex distance (MRD1) and pupil to brow distance (PTB) with weight on the weighted and unweighted sides for normal and ptosis subjects. RESULTS: The weighted eyelid MRD1 decreased linearly with increasing weight. This was true for normal and ptosis subjects. The unweighted eyelid MRD1 increased linearly with increasing weight. This was also the case for both normal and ptosis subjects. With increasing weight, PTB increased linearly on the weighted side. No significant intergroup differences were noted. CONCLUSIONS: In normal and ptosis subjects, when external weight on the eyelid is incrementally increased, the weighted eyelid MRD1 decreases, the unweighted eyelid MRD1 increases, and both brows elevate in a linear fashion.

ABSTRACT

BACKGROUND: Low-energy lateral ankle injuries (Salter-Harris 1 distal fibula, distal fibula avulsion fractures, and radiograph-negative lateral ankle injuries) are common in pediatric patients. Patient-based outcomes for the 2 treatment options, short leg walking cast (CAST) and controlled ankle motion (CAM) boot, are unknown. This study aims to determine differences between 2 treatments of low-energy lateral ankle injuries in pediatric patients. METHODS: A prospective, randomized controlled trial comparing the acute outcomes of CAST and CAM treatment for low-energy lateral ankle injuries in pediatric patients was completed. Patients were evaluated in-person at presentation and 4 weeks for ankle range of motion and Oxford foot and ankle score. A novel survey defining patient and parent satisfaction and time away from school/work was also completed. Treatment complications were documented. Patients were called at 8 weeks postinjury to determine other complications and the final time of return to sport. Mixed effects linear regression models evaluated change over time between the 2 treatment groups. RESULTS: After 60 patients were enrolled, 28 patients in the CAST group and 27 patients in the CAM group completed the study. Males comprised 51% (28), with 38 (69%) patients identifying as Hispanic. The patient's average age was 11.3±2.9 years and the average body mass index was 23.At the 4-week evaluation, the CAM group had improved range of motion, higher satisfaction scores (5.26 CAM vs. 4.25 CAST, P <0.05), similar pain scores (0.32 CAST vs. 0.41 CAM, P =0.75), and lower complications (0.54/patient CAST vs. 0.04/patient CAM, P <0.0001) than the CAST group. Female patients had improved inversion with CAM treatment than males ( P <0.05). Patients over age 12 in the CAST group had significantly decreased plantarflexion at week 4 ( P =0.002). Improvement in Oxford scores was similar between the CAST and CAM groups between the initial presentation and 4 weeks, except for increased improvement in CAM group Oxford scores for difficulty running and symptoms with walking/walking. At the 8-week evaluation, patients in the CAST group had a higher rate of continued symptoms than the CAM group (15.4% vs. 0%). CONCLUSIONS: CAM boot treatment of low-energy lateral ankle injuries in pediatric patients results in improved results and lower complications than CAST treatment. LEVEL OF EVIDENCE: Level I -randomized, controlled trial with a statistically significant difference.

ABSTRACT

PURPOSE: Microscopic hematuria is one of the most common office consults for urologists. While revised guidelines have risk-stratified patients to reduce unnecessary screening, they do not provide guidance concerning specimen quality. We sought to define "properly collected" specimens using catheterized urine samples as a reference to improve the utility of hematuria screening in women. MATERIALS AND METHODS: We prospectively acquired same-visit voided and catheterized urine samples from 46 women referred for microscopic hematuria from September 2016 to March 2020. Characteristics of pre-referral urinalysis were compared to the matched specimens. True microscopic hematuria was defined as ≥3 red blood cells per high power field on catheterization. RESULTS: Catheterized urinalyses had significantly fewer red blood and squamous epithelial cells in comparison to both referral urinalyses (p=0.006, p=0.001, respectively) and same-day void urinalyses (p=0.02, p=0.04, respectively). As no catheterized sample had >2 squamous epithelial cells, we applied this squamous epithelial cell threshold to referral urinalyses for analysis. Addition of this criterion for "properly collected specimen" increased the positive predictive value of referral urinalyses from 46.1% to 68.8% for true microscopic hematuria. Fewer than 2 squamous epithelial cells with elevated RBC was a significant predictor for true microscopic hematuria (p=0.003). CONCLUSIONS: Voided specimens in the urology clinic had significantly lower red blood cells than referral samples, indicating improved collection technique may reduce false positive urinalyses. Matched collection suggested that repeat collection by catheterization in women who present with >2 squamous epithelial cells per high power field on referral urinalysis may prevent unnecessary future work-up.

ABSTRACT

BACKGROUND: Since the onset of the COVID-19 pandemic, telehealth has been an option for Veterans receiving urgent care through Veterans Health Administration Community Care (CC). OBJECTIVE: We assessed use, arrangements, Veteran decision-making, and experiences with CC urgent care delivered via telehealth. DESIGN: Convergent parallel mixed methods, combining multivariable regression analyses of claims data with semistructured Veteran interviews. SUBJECTS: Veterans residing in the Western United States and Hawaii, with CC urgent care claims March 1 to September 30, 2020. KEY RESULTS: In comparison to having in-person only visits, having a telehealth-only visit was more likely for Veterans who were non-Hispanic Black, were urban-dwelling, lived further from the clinic used, had a COVID-related visit, and did not require an in-person procedure. Predictors of having both telehealth and in-person (compared with in-person only) visits were other (non-White, non-Black) non-Hispanic race/ethnicity, urban-dwelling status, living further from the clinic used, and having had a COVID-related visit. Care arrangements varied widely; telephone-only care was common. Veteran decisions about using telehealth were driven by limitations in in-person care availability and COVID-related concerns. Veterans receiving care via telehealth generally reported high satisfaction. CONCLUSIONS: CC urgent care via telehealth played an important role in providing Veterans with care access early in the COVID-19 pandemic. Use of telehealth differed by Veteran characteristics; lack of in-person care availability was a driver. Future work should assess for changes in telehealth use with pandemic progression, geographic differences, and impact on care quality, care coordination, outcomes, and costs to ensure Veterans' optimal and equitable access to care.

ABSTRACT

BACKGROUND: Schools and school climate are thought to influence academic outcomes as well as child and adolescent development, health and well-being. We sought to examine the relationship between several aspects of the school climate with adolescent social-emotional health outcomes. METHODS: We analysed data from the Reducing Inequities through Social and Educational change Follow-up (RISE UP) Study, a longitudinal natural experimental study of Los Angeles high school students collected from 2013 to 2018. We analysed data on the portion of the sample that completed the baseline, 10th grade and 11th grade surveys (n=1114). Students reported their perceptions of school climate at 10th grade and social-emotional outcomes including grit, self-efficacy, depression, hopelessness, and stress at baseline (9th grade) and at 11th grade. Multivariable regressions adjusted for student and parental demographics and baseline social-emotional states tested associations between school climate and each outcome. RESULTS: Students who reported being in authoritative school environments in 10th grade, one that is highly supportive and highly structured, had subsequently higher levels of self-efficacy (p< 0.001) and grit (p=0.01). They also had fewer depressive symptoms (p=0.008), and less hopelessness (p = 0.01), stress at school (p=0.002) and stress about the future (p=0.03) reported in 11th grade. CONCLUSIONS: School climate, and particularly an authoritative school environment, is strongly associated with better social-emotional health among adolescents. Relationship with teachers and their disciplinary style may be a focus for future interventions to improve the social-emotional health of children.

ABSTRACT

BACKGROUND: Type 2 diabetes can negatively impact long term health outcomes, healthcare costs and quality of life. However, intensive lifestyle interventions, including the Diabetes Prevention Program (DPP), can significantly lower risk of incident type 2 diabetes among overweight adults with prediabetes. Unfortunately, the majority of adults in the US who are at risk of developing diabetes do not engage in DPP-based lifestyle change programs. Increased adoption of evidence-based obesity and diabetes prevention interventions, such as the DPP, may help large employers reduce health risks and improve health outcomes among employees. In 2018, the University of California Office of thePresident (UCOP) implemented the UC DPP Initiative, a novel, multi-component program to address diabetes and obesity prevention across the UC system. METHODS: The goal of our study is to conduct a multifaceted evaluation of the UC DPP Initiative using the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework. Our evaluation will integrate unique and diverse UC data sources, including electronic health record (EHR) data, administrative claims, campus-based DPP cohort data, qualitative interviews and site visits. Our primary outcome of interest is the mean percent weight change among three groups of overweight/obese UC beneficiaries at risk for diabetes at 12-month follow-up. Secondary outcomes include mean percent weight change at 24-month follow-up, barriers and facilitators associated with implementatio, as well as  the degree of program adoption and maintenance. DISCUSSION: Our study will help inform diabetes and obesity prevention efforts across the UC system. Findings from this evaluation will also be highly applicable to universities and large employers, as well as community organizers, healthcare organizations and insurers implementing the DPP and/or other health promotion interventions.

ABSTRACT

INTRODUCTION: Trochlear dysplasia is a known risk factor for patellar dislocations yet normal trochlea development is not well described. This study will define the articular cartilage (AC) and subchondral trochlear morphology development in pediatric patients using magnetic resonance imaging (MRI) evaluation. METHODS: A retrospective knee MRI review included patients aged 3 to 16 years with nonpatellofemoral-related diagnoses. International classification of diseases-9/International classification of diseases-10 codes were used to identify eligible study patients. Measurements of the trochlea were made on the basis of previously established methods using the axial MRI just distal to the physis at the deepest portion of the trochlear groove. Three linear [lateral trochlear height (LTH), medial trochlear height (MTH), and central trochlear height (CTH)] and 3 angular [sulcus angle (SA), lateral trochlear slope (LTS), and medial trochlear slope (MTS)] were made at AC and subchondral bone (SCB). The 12 measurements were made independently by 2 study authors. Inter-rater reliability was assessed using an interclass correlation coefficient for absolute agreement to the average of the scores. Trochlea measurements were summarized across age quartiles defined as first quartile (age, 5.1 to 8.3 y), second quartile (8.3 to 11.5 y), third quartile (11.5 to 14.3 y), fourth quartile (14.3to 16.9 y). Associations between age and trochlea measures were assessed using linear regression with Huber-White-adjusted SEs to account for clustering from a small number of patients (N=16) with >1 MRI. RESULTS: In total, 246 knee MRIs from 230 patients were included in this study; 113 patients (51%) were female, whereas 117 (49%) were male. A total of 116 MRIs (47%) were of the left knee and 130 (53%) were right knee. The average patient age was 11.4±3.4 years. Inter-rater agreement was high across all measures with interclass correlation coefficient values >0.7. Mean values for measurements are presented by age quartiles. LTH, MTH, and CTH showed a linear increase with age (range, 2 to 2.6 cm/y; P<0.001). SA, LTS, MTS measured at AC showed no change with age (P>0.05); however, LTS and MTS measured at SCB showed significant increases with age (0.6 and 0.9 degrees/y; P<0.001), whereas SA showed a decrease with age (-1.4 degrees/y; P<0.001). There were no significant differences found in the age associations by laterality, left versus right. There were no sex differences in the age associations for SA, LTS (P>0.05); however, for MTH, LTH, and CTH, males were found to have a significantly greater growth rate (P<0.001). CONCLUSIONS: This study found an increase in AC and SCB MTH, LTH, and CTH over time, as well as an increase in SCB LTS and MTS, with a decrease in SA. However, AC of the LTS and SA remained constant, with no significant change throughout growth. This normative data indicate that the LTS and SA of AC are predictors of final trochlea shape in normal development. Final trochlear morphologic development is nearly complete around age 12 years, with no significant changes occurring thereafter.

ABSTRACT

Background and Purpose- Lowering blood pressure and cholesterol, antiplatelet/antithrombotic use, and smoking cessation reduce risk of recurrent stroke. However, gaps in risk factor control among stroke survivors warrant development and evaluation of alternative care delivery models that aim to simultaneously improve multiple risk factors. Randomized trials of care delivery models are rarely of sufficient duration or size to be powered for low-frequency outcomes such as observed recurrent stroke. This creates a need for tools to estimate how changes across multiple stroke risk factors reduce risk of recurrent stroke. Methods- We reviewed existing evidence of the efficacy of interventions addressing blood pressure reduction, cholesterol lowering, antiplatelet/antithrombotic use, and smoking cessation and extracted relative risks for each intervention. From this, we developed a tool to estimate reductions in recurrent stroke risk, using bootstrapping and simulation methods. We also calculated a modified Global Outcome Score representing the proportion of potential benefit (relative risk reduction) achieved if all 4 individual risk factors were optimally controlled. We applied the tool to estimate stroke risk reduction among 275 participants with complete 12-month follow-up data from a recently published randomized trial of a healthcare delivery model that targeted multiple stroke risk factors. Results- The recurrent stroke risk tool was feasible to apply, yielding an estimated reduction in the relative risk of ischemic stroke of 0.36 in both the experimental and usual care trial arms. Global Outcome Score results suggest that participants in both arms likely averted, on average, 45% of recurrent stroke events that could possibly have been prevented through maximal implementation of interventions for all 4 individual risk factors. Conclusions- A stroke risk reduction tool facilitates estimation of the combined impact on vascular risk of improvements in multiple stroke risk factors and provides a summary outcome for studies testing alternative care models to prevent recurrent stroke.

ABSTRACT

BACKGROUND: Medical, behavioral, and social determinants of health are each associated with high levels of emergency department (ED) visits and hospitalizations. OBJECTIVE: The objective of this study was to evaluate a care coordination program designed to provide combined "whole-person care," integrating medical, behavioral, and social support for high-cost, high-need Medicaid beneficiaries by targeting access barriers and social determinants. RESEARCH DESIGN: Individual-level interrupted time series with a comparator group, using person-month as the unit of analysis. SUBJECTS: A total of 42,214 UnitedHealthcare Medicaid beneficiaries (194,834 person-months) age 21 years or above with diabetes, with Temporary Assistance to Needy Families, Medicaid expansion, Supplemental Security Income without Medicare, or dual Medicaid/Medicare. MEASURES: Our outcome measures were any hospitalizations and any ED visits in a given month. Covariates of interest included an indicator for intervention versus comparator group and indicator and spline variables measuring changes in an outcome's time trend after program enrollment. RESULTS: Overall, 6 of the 8 examined comparisons were not statistically significant. Among Supplemental Security Income beneficiaries, we observed a larger projected decrease in ED visit risk among the intervention sample versus the comparator sample at 12 months postenrollment (difference-in-difference: -6.6%; 95% confidence interval: -11.2%, -2.1%). Among expansion beneficiaries, we observed a greater decrease in hospitalization risk among the intervention sample versus the comparator sample at 12 months postenrollment (difference-in-difference: -5.8%; 95% confidence interval: -11.4%, -0.2%). CONCLUSION: A care coordination program designed to reduce utilization among high-cost, high-need Medicaid beneficiaries was associated with fewer ED visits and hospitalizations for patients with diabetes in selected Medicaid programs but not others.

ABSTRACT

BACKGROUND: Hospital readmission rates decreased for myocardial infarction (AMI), heart failure (CHF), and pneumonia with implementation of the first phase of the Hospital Readmissions Reduction Program (HRRP). It is not established whether readmissions fell for chronic obstructive pulmonary disease (COPD), an HRRP condition added in 2014. OBJECTIVE: We sought to determine whether HRRP penalties influenced COPD readmissions among Medicare, Medicaid, or privately insured patients. DESIGN: We analyzed a retrospective cohort, evaluating readmissions across implementation periods for HRRP penalties ("pre-HRRP" January 2010-April 2011, "implementation" May 2011-September 2012, "partial penalty" October 2012-September 2014, and "full penalty" October 2014-December 2016). PATIENTS: We assessed discharged patients ≥ 40 years old with COPD versus those with HRRP Phase 1 conditions (AMI, CHF, and pneumonia) or non-HRRP residual diagnoses in the Nationwide Readmissions Database. INTERVENTIONS: HRRP was announced and implemented during this period, forming a natural experiment. MEASUREMENTS: We calculated differences-in-differences (DID) for 30-day COPD versus HRRP Phase 1 and non-HRRP readmissions. KEY RESULTS: COPD discharges for 1.2 million Medicare enrollees were compared with 22 million non-HRRP and 3.4 million HRRP Phase 1 discharges. COPD readmissions decreased from 19 to 17% over the study. This reduction was significantly greater than non-HRRP conditions (DID - 0.41%), but not HRRP Phase 1 (DID + 0.02%). A parallel trend was observed in the privately insured, with significant reduction compared with non-HRRP (DID - 0.83%), but not HRRP Phase 1 conditions (DID - 0.45%). Non-significant reductions occurred in Medicaid (DID - 0.52% vs. non-HRRP and - 0.21% vs. Phase 1 conditions). CONCLUSIONS: In Medicare, HRRP implementation was associated with reductions in COPD readmissions compared with non-HRRP controls but not versus other HRRP conditions. Parallel findings were observed in commercial insurance, but not in Medicaid. Condition-specific penalties may not reduce readmissions further than existing HRRP trends.

ABSTRACT

BACKGROUND: The long-term impact of oral hepatitis B antiviral therapy in liver transplant (LT) recipients is currently underexplored. The objective of this study was to evaluate how oral antiviral agents impact long-term renal function in this population. METHODS: We studied 79 patients who received a LT for hepatitis B and were placed on all-oral antiviral therapy after withdrawing from hepatitis B immune globulin therapy at the University of California, Los Angeles. Laboratory data were obtained through a retrospective chart review. Univariate analysis and two-sided t tests were performed. RESULTS: The mean (±SD [standard deviation]) age at the time of LT was 65.4 (± 8.2) years. The overall mean (±SD) follow-up from LT was 6.5 (±3.3) years. 22.8% (18/79) of recipients on all-oral therapy had worsening of their chronic kidney disease stage, and 17.7% (14/79) had an increase in creatinine of at least 0.3 mg/dL. There were no significant changes in creatinine and GFR in patients while on tenofovir alafenamide. Patient survival was decreased for recipients who developed detectable HBsAg. CONCLUSION: Tenofovir alafenamide appears to have less of an impact on renal function in LT recipients than other antiviral agents. HBV recurrence after transplant is associated with decreased patient survival and remains an important issue to address for LT recipients on oral antiviral therapy.

ABSTRACT

OBJECTIVE: To determine the effect of age of packed RBCs on tissue oxygenation in children receiving extracorporeal membrane oxygenation support. DESIGN: A retrospective study was done between March 2013 and August 2015. The following biomarkers were examined 6 hours before and 6 hours after the conclusion of a transfusion: serum and circuit hematocrits, serum and circuit venous saturations, serum lactate levels (mg/dL), and cerebral saturation via near-infrared spectroscopy. Biomarkers were examined with respect to time relative to transfusion using four discrete categories (< 3, -3 to 0, 0-3, and > 3 hr). The association between age of blood transfusion and change in biomarkers was accessed analyzing time relative to transfusion as described above. In addition, the age of blood transfusion was analyzed similarly, using four discrete categories (0-7, 7-14, 14-21, and > 21 d). SETTING: Twenty-four bed mixed pediatric medical and cardiac ICU at a tertiary care center. SUBJECTS: Zero- to 18-year-old patients of required extracorporeal membrane oxygenation support. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Circuit venous saturation demonstrated an increase of 2.5% (p < 0.001) in first 3 hours posttransfusion. This was followed by a 1.4% decrease after the initial 3 hours posttransfusion. Serum venous saturation showed no statistically significant change with relation to transfusions. Neither lactate levels nor near-infrared spectroscopy demonstrated any observed statistical change with relation to transfusion. With regards to the relationship between the age of RBC transfusion and tissue oxygenation biomarkers, none of the biomarkers exhibited a consistent interaction. CONCLUSIONS: Our study demonstrates that the age of packed RBC transfusion does not affect the degree tissue oxygenation in children receiving extracorporeal membrane oxygenation support, as measured by mixed venous oxygen saturation, lactate, and near-infrared spectroscopy. In addition, packed RBC transfusion, in general, did not produce any meaningful change in these markers of tissue oxygenation.

ABSTRACT

BACKGROUND: Readmissions following exacerbations of chronic obstructive pulmonary disease (COPD) are prevalent and costly. Multimorbidity is common in COPD and understanding how comorbidity influences readmission risk will enable health systems to manage these complex patients. OBJECTIVES: We compared two commonly used comorbidity indices published by Charlson and Elixhauser regarding their ability to estimate readmission odds in COPD and determine which one provided a superior model. METHODS: We analyzed discharge records for COPD from the Nationwide Readmissions Database spanning 2010 to 2016. Inclusion and readmission criteria from the Hospital Readmissions Reduction Program were utilized. Elixhauser and Charlson Comorbidity Index scores were calculated from published methodology. A mixed-effects logistic regression model with random intercepts for hospital clusters was fit for each comorbidity index, including year, patient-level, and hospital-level covariates to estimate odds of thirty-day readmissions. Sensitivity analyses included testing age inclusion thresholds and model stability across time. RESULTS: In analysis of 1.6 million COPD discharges, readmission odds increased by 9% for each half standard deviation increase of Charlson Index scores and 13% per half standard deviation increase of Elixhauser Index scores. Model fit was slightly better for the Elixhauser Index using information criteria. Model parameters were stable in our sensitivity analyses. CONCLUSIONS: Both comorbidity indices provide meaningful information in prediction readmission odds in COPD with slightly better model fit in the Elixhauser model. Incorporation of comorbidity information into risk prediction models and hospital discharge planning may be informative to mitigate readmissions.

ABSTRACT

Marijuana is one of the most commonly used drugs in the United States, and use during adolescence--when the brain is still developing--has been proposed as a cause of poorer neurocognitive outcome. Nonetheless, research on this topic is scarce and often shows conflicting results, with some studies showing detrimental effects of marijuana use on cognitive functioning and others showing no significant long-term effects. The purpose of the present study was to examine the associations of marijuana use with changes in intellectual performance in two longitudinal studies of adolescent twins (n = 789 and n = 2,277). We used a quasiexperimental approach to adjust for participants' family background characteristics and genetic propensities, helping us to assess the causal nature of any potential associations. Standardized measures of intelligence were administered at ages 9-12 y, before marijuana involvement, and again at ages 17-20 y. Marijuana use was self-reported at the time of each cognitive assessment as well as during the intervening period. Marijuana users had lower test scores relative to nonusers and showed a significant decline in crystallized intelligence between preadolescence and late adolescence. However, there was no evidence of a dose-response relationship between frequency of use and intelligence quotient (IQ) change. Furthermore, marijuana-using twins failed to show significantly greater IQ decline relative to their abstinent siblings. Evidence from these two samples suggests that observed declines in measured IQ may not be a direct result of marijuana exposure but rather attributable to familial factors that underlie both marijuana initiation and low intellectual attainment.
