Reevaluating Associations between Prenatal Care Utilization and Current Trends in Preterm Birth.

OBJECTIVE: Studies have suggested an association between prenatal care (PNC) and preterm birth (PTB). We evaluated trends in PTB and association of PNC and PTB. STUDY DESIGN: This was a retrospective cohort study of singleton, viable nonanomalous deliveries from 1991 to 2018. PNC utilization was defined by World Health Organization using number of visits: adequate (≥8), suboptimal (5-7), and inadequate (<5). Primary outcome was PTB. Tests of trend were used to assess changes in PTB over time. Baseline characteristics and outcomes were compared. Logistic regression estimated the association of PNC and PTB. We evaluated for effect modification by year of birth. RESULTS: Of 92,294 patients, 14,057 (15%) had PTB. Inadequate and suboptimal PNC were associated with higher odds of PTB compared to adequate PNC (adjusted odds ratios [aOR 6.21], 95% confidence interval [CI] 5.84-6.60; aOR 3.57, 95% CI 3.36-3.79). Inadequate PNC was associated with higher odds of PTB over time (effect modification p < 0.0001). Inadequate PNC was associated with 5.4 times higher odds of PTB in 1998, 7.0 times in 2008, and 9.1 times in 2018. CONCLUSION: Despite an increase in adequate PNC, there was a rise in PTB associated with inadequate and suboptimal PNC. PNC utilization was a stronger risk factor in recent years with higher PTB in patients who attended more than five PNC visits. KEY POINTS: · PNC utilization is associated with the risk of PTB.. · Despite an increase in PNC utilization, PTB rates have increased.. · There is an even stronger association between PNC utilization and PTB over time..

Multi-institutional analysis of clinical and imaging risk factors for detecting clinically significant prostate cancer in men with PI-RADS 3 lesions.

BACKGROUND: Most Prostate Imaging-Reporting and Data System (PI-RADS) 3 lesions do not contain clinically significant prostate cancer (CSPCa; grade group ≥2). This study was aimed at identifying clinical and magnetic resonance imaging (MRI)-derived risk fac- tors that predict CSPCa in men with PI-RADS 3 lesions. METHODS: This study analyzed the detection of CSPCa in men who underwent MRI-targeted biopsy for PI-RADS 3 lesions. Multivariable logistic regression models with goodness-of-fit testing were used to identify variables associated with CSPCa. Receiver operating curves and decision curve analyses were used to estimate the clinical utility of a predictive model. RESULTS: Of the 1784 men reviewed, 1537 were included in the training cohort, and 247 were included in the validation cohort. The 309 men with CSPCa (17.3%) were older, had a higher prostate-specific antigen (PSA) density, and had a greater likelihood of an anteriorly located lesion than men without CSPCa (p < .01). Multivariable analysis revealed that PSA density (odds ratio [OR], 1.36; 95% confidence interval [CI], 1.05-1.85; p < .01), age (OR, 1.05; 95% CI, 1.02-1.07; p < .01), and a biopsy-naive status (OR, 1.83; 95% CI, 1.38-2.44) were independently associated with CSPCa. A prior negative biopsy was negatively associated (OR, 0.35; 95% CI, 0.24-0.50; p < .01). The application of the model to the validation cohort resulted in an area under the curve of 0.78. A predicted risk threshold of 12% could have prevented 25% of biopsies while detecting almost 95% of CSPCas with a sensitivity of 94% and a specificity of 34%. CONCLUSIONS: For PI-RADS 3 lesions, an elevated PSA density, older age, and a biopsy-naive status were associated with CSPCa, whereas a prior negative biopsy was negatively associated. A predictive model could prevent PI-RADS 3 biopsies while missing few CSPCas. LAY SUMMARY: Among men with an equivocal lesion (Prostate Imaging-Reporting and Data System 3) on multiparametric magnetic resonance imaging (mpMRI), those who are older, those who have a higher prostate-specific antigen density, and those who have never had a biopsy before are at higher risk for having clinically significant prostate cancer (CSPCa) on subsequent biopsy. However, men with at least one negative biopsy have a lower risk of CSPCa. A new predictive model can greatly reduce the need to biopsy equivocal lesions noted on mpMRI while missing only a few cases of CSPCa.

Waistline to gumline: a retrospective analysis of body mass index in treated periodontitis patients undergoing periodontal maintenance therapy.

Periodontal disease affects 42% of adults in the United States. Both the periodontal microbiome and the host immune inflammatory response may be influenced by overweight/obesity status. This retrospective analysis sought to determine the associations of periodontal disease parameters with body mass index (BMI) and obesity status in patients undergoing periodontal maintenance therapy. The records of 418 patients who were undergoing periodontal maintenance after periodontitis treatment were examined, and the patients' demographic characteristics (sex, age, and race/ethnicity), self-reported BMI, periodontal disease condition, number of sites with probing depth ≥ 4 mm, missing teeth, and sites with bleeding on probing (BOP) were recorded. Patients were determined to have active moderate to severe periodontitis if they presented with 2 or more sites in 2 different quadrants with clinical attachment loss ≥ 5 mm and probing depth ≥ 5 mm. Individuals were also categorized into 3 groups: underweight/normoweight, BMI < 25; overweight, BMI 25 ≤ 30; or obese, BMI ≥ 30. In the study population, BMI ranged from 16.827 to 51.389. The periodontitis status was not significantly associated with a BMI status of overweight (odds ratio [OR] = 1.388 [95% CI, 0.961- 2.006]) or obese (OR = 1.168 [95% CI, 0.77-1.757]). Female sex (OR = 0.561 [95% CI, 0.343-0.918]) and age (OR = 0.983 [95% CI, 0.967-0.999]) were negatively associated with active periodontitis status. Obese patients demonstrated significantly more sites with BOP than either underweight/normoweight or overweight patients, and a BMI indicating obesity was associated with increasing age (P < 0.001) and higher number of missing teeth (P = 0.0064). In a population of patients undergoing periodontal maintenance therapy, BMI was associated with age and missing teeth, and obese status was associated with a significantly higher number of sites with BOP.

Evaluating the Highest- and Lowest-cited Research Articles in the Cardiothoracic Surgery Literature.

BACKGROUND: Understanding the differences between articles that amass a high number of citations and those that receive very few allows investigators to write journal articles that maximize the impact of their research. There are minimal data regarding these two cohorts in the cardiothoracic surgery literature. METHODS: We identified all primary research articles from 1998 to 2008 from The Journal of Thoracic and Cardiovascular Surgery, The Journal of Cardiac Surgery, The Annals of Thoracic Surgery, and The European Journal of Cardio-Thoracic Surgery (n = 4276). Eighty-seven of these articles accrued 0 or only 1 citation within 10 y of publication. We compared this "low citation" cohort to the "high citation" cohort made up of the 87 highest-cited articles from the same journals over the same time period. RESULTS: When compared with the low-citation articles, high-citation articles were significantly more likely to be clinical in nature (P < 0.0001), have observational study design (P < 0.0001), involve multidisciplinary authorship (P < 0.0001), and have more funding reported (P = 0.0039). With regard to technical aspects of the article, the high-citation articles were likely to have longer titles (P = 0.0086), punctuation in the title (P = 0.0027), longer abstracts (P = 0.0007), more words in the manuscript (P < 0.0001), more authors (P < 0.0001), more declared conflict of interests (P = 0.0167), more references (P < 0.0001), more tables (P < 0.0001), more figures (P = 0.0024), and more pages (P < 0.0001). There was no significant difference in the year of publication among both cohorts. CONCLUSIONS: This review suggests that there are several important distinguishing characteristics that should be considered by investigators when designing and implementing cardiothoracic research studies to maximize the impact of their published research.

Lifecourse socioeconomic position and diabetes incidence in the REasons for Geographic and Racial Differences in Stroke (REGARDS) study, 2003 to 2016.

Low socioeconomic position (SEP) across the lifecourse is associated with Type 2 diabetes (T2DM). We examined whether these economic disparities differ by race and sex. We included 5448 African American (AA) and white participants aged ≥45 years from the national (United States) REasons for Geographic and Racial Differences in Stroke (REGARDS) cohort without T2DM at baseline (2003-07). Incident T2DM was defined by fasting glucose ≥126 mg/dL, random glucose ≥200 mg/dL, or using T2DM medications at follow-up (2013-16). Derived SEP scores in childhood (CSEP) and adulthood (ASEP) were used to calculate a cumulative (CumSEP) score. Social mobility was defined as change in SEP. We fitted race-stratified logistic regression models to estimate the association between each lifecourse SEP indicator and T2DM, adjusting for covariates; additionally, we tested SEP-sex interactions. Over a median of 9.0 (range 7-14) years of follow-up, T2DM incidence was 167.1 per 1000 persons among AA and 89.9 per 1000 persons among white participants. Low CSEP was associated with T2DM incidence among AA (OR = 1.61; 95%CI 1.05-2.46) but not white (1.06; 0.74-2.33) participants; this was attenuated after adjustment for ASEP. In contrast, low CumSEP was associated with T2DM incidence for both racial groups. T2DM risk was similar for stable low SEP and increased for downward mobility when compared with stable high SEP in both groups, whereas upward mobility increased T2DM risk among AAs only. No differences by sex were observed. Among AAs, low CSEP was not independently associated with T2DM, but CSEP may shape later-life experiences and health risks.

Effect of darifenacin on fecal incontinence in women with double incontinence.

INTRODUCTION AND HYPOTHESIS: To evaluate change in fecal incontinence symptom severity after 8 weeks of darifenacin therapy in patients with double incontinence-urgency urinary incontinence (UUI) and fecal incontinence. Important secondary outcomes included fecal incontinence symptom distress and impact on quality of life, fecal incontinence episodes, global impression of improvement and overactive bladder symptom distress and impact. METHODS: Prospective open-label cohort study of women presenting primarily with UUI, diagnosed with double incontinence and electing antimuscarinic therapy for UUI. Women ≥ 18 years with moderate or greater bothersome UUI and fecal incontinence of liquid/solid stool with St. Marks (Vaizey) score ≥ 12 were included. Subjects were treated with darifenacin 15 mg daily for 8 weeks. The primary outcome was change in fecal incontinence symptom severity using the St. Marks (Vaizey) score after 8 weeks. Sample size was based on the minimally important difference of the St. Marks, -5, and standard deviation, ± 8.5; 30 subjects provided 80% power and type I error of 0.05, including a 15% attrition rate. RESULTS: Thirty-two women were consented with mean baseline St. Marks (Vaizey) score of 18.0 ± 3.0. Mean age was 66.5 ± 10.3 years. Twenty-eight subjects (29/32, 87.5%) completed assessments. St. Marks (Vaizey) score significantly improved from 18.0 to 11.0 [mean difference - 7.0, 95% confidence interval (CI): -8.7, -5.3], and 19 subjects (19/32,67.9%) met the minimally important difference. Statistically significant improvements were also noted in fecal incontinence frequency, quality of life, and overactive bladder symptom bother and quality of life (all p < 0.01). CONCLUSIONS: Darifenacin can be considered a highly effective early intervention in women suffering from double incontinence.

Incontinence outcomes after "second primary" compared to repeat midurethral sling for recurrent and persistent stress urinary incontinence.

INTRODUCTION AND HYPOTHESIS: The current study aims to assess the continence rate of a "second primary" midurethral sling (MUS) in women with recurrent/persistent stress urinary incontinence (SUI) after sling excision compared to a historical cohort who underwent a repeat MUS. METHODS: A retrospective cohort study of women who underwent excision of a primary MUS and placement of a "second primary" MUS from 2009 to 2016 compared to a historical cohort who underwent a repeat MUS from 2006 to 2009. The primary outcome was continence rate, defined as "not at all" or "somewhat" to Urogenital Distress Inventory (UDI-6) SUI subscale questions. Secondary outcomes included assessment of symptom severity (UDI-6), symptom-specific quality of life, Incontinence Impact Questionnaire (IIQ-7), Medical and Epidemiologic Aspects of Aging (MESA), and Patient Global Impression of Improvement (PGI-I). RESULTS: Survey responses were available for 23/64 (36%) in the "second primary" MUS group versus 88/135 (65%) in the historical cohort. Mean follow-up in months, second primary: 41.8 ± 26.1 versus repeat: 36.2 ± 14.1, p = 0.16 and age (years): 56.4 ± 10.7 versus 59.8 ± 10.8, p = 0.19. Continence rates were 48% in "second primary" versus 56% in the repeat group (p = 0.50). Both groups had significant improvement in questionnaire scores postoperatively with no intergroup differences. Multivariable analysis demonstrated that odds of success did not differ between groups (adjusted odds ratio: 0.73, 95% confidence interval: 0.27-1.99). CONCLUSIONS: In women with recurrent/persistent SUI, repeat and "second primary" MUS procedures demonstrate similar success outcomes and improvement in UI symptom distress and QOL. Continued research is needed for this increasingly important clinical question.

Short-, mid-, and long-term incontinence outcomes in women undergoing mid-urethral sling procedures: a retrospective cohort study.

INTRODUCTION AND HYPOTHESIS: The primary aim was to compare subjective treatment success among women in short-, mid-, and long-term follow-up after mid-urethral sling (MUS). Symptom severity, condition-specific quality of life (QOL), and patient satisfaction were also examined. METHODS: Women undergoing a primary MUS between 2001 and 2010 were identified by CPT code. Eligible subjects were mailed the Urogenital Distress Inventory (UDI-6), Pelvic Floor Impact Questionnaire (PFIQ-7), Patient Global Impression of Improvement (PGI-I), and Patient Satisfaction Questionnaire (PSQ). Follow-up intervals were short term (≤ 36 months), mid term (37-70 months), and long term (119-200 months). The primary outcome of treatment success was defined as responses of "not at all" or "somewhat" to both stress urinary incontinence (SUI) subscales on the UDI-6. RESULTS: Of 896 respondents, 361 were assessed in the short-term (23.3 ± 7.2 months), 251 in the mid-term (49.8 ± 9.1 months), and 284 in the long-term group (147.9 ± 20.6 months). Treatment success was 75.4% in the short-, 62.3% in the mid-, and 67.0% in the long-term groups (p < 0.01). Logistic regression showed women with mid- and long-term follow-up were nearly half as likely as their short-term counterparts to report treatment success (adjusted odds ratio [aOR] 0.51, 95% confidence interval [CI] 0.36, 0.74). UDI-6 and PFIQ-7 scores differed significantly among the short-, mid- and long-term groups (p < 0.01). Patient satisfaction was similar, 83.3% in the short-, 76.6% in the mid-, and 78.2% in the long-term follow-up (p = 0.31). CONCLUSION: Women with short-term follow-up had the highest subjective treatment success rates; mid- and long-term follow-up was lower, but sustained after 3 years. Symptom severity and impact on QOL were lowest in the short-term group. However, high satisfaction was noted across all groups.

Impact of Multiple Social Determinants of Health on Incident Stroke.

BACKGROUND AND PURPOSE: Social determinants of health (SDOH) have been previously associated with incident stroke. Although SDOH often cluster within individuals, few studies have examined associations between incident stroke and multiple SDOH within the same individual. The objective was to determine the individual and cumulative effects of SDOH on incident stroke. METHODS: This study included 27 813 participants from the REGARDS (Reasons for Geographic and Racial Differences in Stroke) Study, a national, representative, prospective cohort of black and white adults aged ≥45 years. SDOH was the primary exposure. The main outcome was expert adjudicated incident stroke. Cox proportional hazards models examined associations between incident stroke and SDOH, individually and as a count of SDOH, adjusting for potential confounders. RESULTS: The mean age was 64.7 years (SD 9.4) at baseline; 55.4% were women and 40.4% were blacks. Over a median follow-up of 9.5 years (IQR, 6.0-11.5), we observed 1470 incident stroke events. Of 10 candidate SDOH, 7 were associated with stroke (P<0.10): race, education, income, zip code poverty, health insurance, social isolation, and residence in one of the 10 lowest ranked states for public health infrastructure. A significant age interaction resulted in stratification at 75 years. In fully adjusted models, among individuals <75 years, risk of stroke rose as the number of SDOH increased (hazard ratio for one SDOH, 1.26 [95% CI, 1.02-1.55]; 2 SDOH hazard ratio, 1.38 [95% CI, 1.12-1.71]; and ≥3 SDOH hazard ratio, 1.51 [95% CI, 1.21-1.89]) compared with those without any SDOH. Among those ≥75 years, none of the observed effects reached statistical significance. CONCLUSIONS: Incremental increases in the number of SDOH were independently associated with higher incident stroke risk in adults aged <75 years, with no statistically significant effects observed in individuals ≥75 years. Targeting individuals with multiple SDOH may help reduce risk of stroke among vulnerable populations.

Differences in Highly-Cited and Lowly-Cited Manuscripts in Plastic Surgery.

BACKGROUND: There is a paucity of research comparing journal articles that accrue numerous citations with those that accrue few citations over time. Understanding differences between journal articles can help direct investigators in designing and conducting their research. METHODS: Using advanced bibliometric tools, we queried four plastic surgery journals (Journal of Reconstructive Microsurgery, Annals of Plastic Surgery, Plastic and Reconstructive Surgery, and Microsurgery) for primary research articles published between 1998 and 2008 accruing zero or one citations with at least a 10-y lag time. Forty-seven articles were identified as low citation and were compared with an equal number of articles in the same journals that accrued the highest number of citations in the same period as high citation (HC). The data were analyzed using Student t-tests, Wilcoxon rank sum tests, chi-square tests, and Fisher exact tests. The level of significance was established at P < 0.05. RESULTS: When compared with the HC cohort, the low citation articles were more likely to be nonclinical (P < 0.001), have no plastic surgery authors (P = 0.0026), and focus on the field of microsurgery (P = 0.003). The HC cohort was more likely to have higher sample sizes (P = 0.0339), focus on aesthetic/cosmetic surgery (P = 0.003), have a higher number of other disciplines included on authorship (P < 0.001), references (P = 0.0451), manuscript pages (P < 0.001), and words in the abstract (P < 0.001). CONCLUSIONS: A small number of articles published in four plastic surgery journals were uncited during a 10-y period. There are qualitative and quantitative differences between highly and lowly cited articles in the plastic surgery literature. Investigators should consider these differences when designing and conducting studies.

Factors Associated With Low and High Article Citations in the Oral and Maxillofacial Surgery Literature.

PURPOSE: We assessed the factors in reported oral and maxillofacial surgery (OMS) studies associated with the number of citations. MATERIALS AND METHODS: We identified all primary research studies reported from 1998 to 2008 in the International Journal of Oral and Maxillofacial Surgery, Journal of Oral Maxillofacial Surgery (JOMS), British Journal of Oral Maxillofacial Surgery (BJOMS), and Journal of Craniomaxillofacial Surgery. Of the identified studies, 66 had obtained only 0 to 3 citations in the 10 years after publication. We compared these lowest cited reports with the 66 highest cited reports. The characteristics of the lowest and highest cited studies were compared using bivariate analysis. Logistic regression analysis using generalized estimating equations was conducted to examine the association between the selected article-, author-, and journal-level characteristics and high citations. RESULTS: On the initial bivariate analysis, highly cited studies were associated with greater abstract and manuscript word counts (P < .0001), manuscript pages (P < .0001), figures (P = .0482), sample sizes (P = .0149), and references (P < .0001). They were also more likely to have reported a significant result (P = .0202), been published in JOMS (P = .0405), and covered topics such as dentoalveolar/implantology and trauma/reconstruction (P = .0002). Lowly cited articles were more likely to have been published in BJOMS (P = .0405) and addressed topics unrelated to core OMS procedures (P = .0002). The H-indexes of the first and corresponding authors were greater in the high-citation group (P < .0001). After multivariate analysis, a greater number of manuscript pages (P = .0015) and classification as dentoalveolar/implantology (P = .0017) or trauma/reconstruction (P = .0368) had greater odds of high citations. In addition, a higher H-index for the first author made it more likely to be in the high-citation group (P = .0397). CONCLUSIONS: Relatively few studies in the OMS literature failed to produce citations in the 10 years after publication, indicating that most studies accepted for publication provide meaningful contributions. Significant differences were found between the highest and lowest cited publications, suggesting that study design and article structure might influence the articles' audience and effect.

Current Practice and Clinical Utility of Thrombophilia Testing in Hospitalized Patients with Acute Ischemic Stroke.

BACKGROUND AND PURPOSE: Testing for thrombophilic disorders is often performed in patients after cryptogenic ischemic stroke in an attempt to identify a hematologic explanation for the event. However, the role of commonly tested thrombophilias in ischemic stroke is poorly defined. There is limited evidence to quantify how these disorders affect ischemic stroke risk and testing practices are highly variable. METHODS: Retrospective evaluation of thrombophilia testing practices and clinical outcomes was performed in hospitalized patients with acute ischemic stroke (n = 1898) at a large academic hospital over a two-year period. Variables assessed included testing components, timing of testing, number of abnormal results, and frequency of change in clinical management prompted by abnormal results. A provider survey was also performed to assess perceptions of current testing practices and provider understanding of testing indications. RESULTS: Thrombophilia testing was performed in 190 (10%) patients admitted for acute ischemic stroke. Of those tested, 137 (72.1%) had at least one abnormal result, but this decreased to 37.4% when elevated factor VIII activity was excluded. An abnormal result prompted initiation of anticoagulation in only 4 patients (2%). The provider survey indicated that all providers (100%) were selecting thrombophilia tests using a pre-existing order set and were interested in additional education on testing indications and interpretation. Comparison to similar studies at other institutions revealed significant variation in testing practices, and a small proportion of patients in which testing prompted a change in management (1-8%). CONCLUSIONS: Thrombophilia testing is frequently obtained in hospitalized patients with acute ischemic stroke, yet testing only changed management in 2% of patients. Efforts to improve provider education and the stewardship of testing are needed to ensure appropriate evaluation and treatment of patients with acute ischemic stroke.

Adherence to Mediterranean-style diet and risk of sepsis in the REasons for Geographic and Racial Differences in Stroke (REGARDS) cohort.

Sepsis - syndrome of infection complicated by organ dysfunction - is responsible for over 750 000 hospitalisations and 200 000 deaths in the USA annually. Despite potential nutritional benefits, the association of diet and sepsis is unknown. Therefore, we sought to determine the association between adherence to a Mediterranean-style diet (Med-style diet) and long-term risk of sepsis in the REasons for Geographic Differences in Stroke (REGARDS) cohort. We analysed data from REGARDS, a population-based cohort of 30 239 community-dwelling adults age ≥45 years. We determined dietary patterns from a baseline FFQ. We defined Med-style diet as a high consumption of fruit, vegetables, legumes, fish, cereal and low consumption of meat, dairy products, fat and alcohol categorising participants into Med-style diet tertiles (low: 0-3, moderate: 4-5, high: 6-9). We defined sepsis events as hospital admission for serious infection and at least two systematic inflammatory response syndrome criteria. We used Cox proportional hazard models to determine the association between Med-style diet tertiles and first sepsis events, adjusting for socio-demographics, lifestyle factors, and co-morbidities. We included 21 256 participants with complete dietary data. Dietary patterns were: low Med-style diet 32·0 %, moderate Med-style diet 42·1 % and high Med-style diet 26·0 %. There were 1109 (5·2 %) first sepsis events. High Med-style diet was independently associated with sepsis risk; low Med-style diet referent, moderate Med-style diet adjusted hazard ratio (HR) 0·93 (95 % CI 0·81, 1·08), high Med-style diet adjusted HR=0·74 (95 % CI 0·61, 0·88). High Med-style diet adherence is associated with lower risk of sepsis. Dietary modification may potentially provide an option for reducing sepsis risk.

Impact of age on mid- to long-term outcomes of transvaginal native tissue repair for apical vaginal prolapse.

AIMS: To compare surgical success rates in older versus younger women a minimum of 3 years post transvaginal native tissue repair for apical prolapse. Post-operative symptom severity and quality of life improvement, surgical complications and retreatment were also examined. METHODS: Women who underwent transvaginal native tissue repair for apical prolapse between 2011 and 2013 were eligible. Subjects completed the pelvic floor distress inventory (PFDI-20), pelvic floor impact questionnaire (PFIQ-7), and patient global impression of improvement (PGI-I), and were categorized as "younger" (age <70) or "older" (age ≥70). The primary outcome of surgical success was defined as the absence of bulge symptoms and no re-treatment for prolapse. RESULTS: Of 641 eligible patients, response rate was 51.0%. 62.7% of subjects had hysterectomy prior to index surgery. Surgical success was noted in 72.9% of younger and 82.2% of older subjects (Adjusted odds ratio [aOR] 1.72, 95% CI [0.93, 3.17]). Older women had greater improvement from baseline in PFDI-20 score (-87.5 [IQR 74.0] vs -54.2 [IQR 80.2], P = 0.01). Retreatment rate and surgical complication rates were similar between groups (both P > 0.05). CONCLUSIONS: Older and younger women had similar surgical success rates a minimum of 3 years post-operative; however, older women had a greater overall symptom severity improvement. This information may be helpful in counseling older women regarding surgical expectations and decision-making.

Furosemide Response Predicts Acute Kidney Injury After Cardiac Surgery in Infants and Neonates.

OBJECTIVE: Cardiac surgery-induced acute kidney injury occurs frequently in neonates and infants and is associated with postoperative morbidity/mortality; early identification of cardiac surgery-induced acute kidney injury may be crucial to mitigate postoperative morbidity. We sought to determine if hourly or 6-hour cumulative urine output after furosemide in the first 24 hours after cardiopulmonary bypass could predict development of cardiac surgery-induced acute kidney injury and other deleterious outcomes. DESIGN: Retrospective chart review. SETTING: Pediatric cardiac ICU. PATIENTS: All infants younger than 90 days old admitted to the cardiac ICU from October 2012 to December 2015 who received at least one dose of furosemide in the first 24 hours after cardiopulmonary bypass surgery. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Ninety-nine patients met inclusion and exclusion criteria. In total, 45.5% developed cardiac surgery-induced acute kidney injury. Median time between cardiopulmonary bypass and furosemide was 7.7 hours (interquartile range, 4.4-9.5). Six-hour cumulative urine output was 33% lower (p = 0.031) in patients with cardiac surgery-induced acute kidney injury. Area under the curve for prediction of cardiac surgery-induced acute kidney injury was 0.69 (p = 0.002). Other models demonstrated urine output response to furosemide had significant area under the curves for prediction of peak fluid over load greater than 15% (0.68; p = 0.047), prolonged peritoneal dialysis (area under the curve, 0.79; p = 0.007), prolonged mechanical ventilation (area under the curve, 0.79; p < 0.001), prolonged hospitalization (area under the curve, 0.62; p = 0.069) and mortality (area under the curve, 0.72; p = 0.05). CONCLUSIONS: Urine output response to furosemide within 24 hours of cardiopulmonary bypass predicts cardiac surgery-induced acute kidney injury development and other important morbidity in children younger than 90 days old; prospective validation is warranted.

Development of dilated cardiomyopathy and impaired calcium homeostasis with cardiac-specific deletion of ESRRß.

Mechanisms underlying the development of idiopathic dilated cardiomyopathy (DCM) remain poorly understood. Using transcription factor expression profiling, we identified estrogen-related receptor-ß (ESRRß), a member of the nuclear receptor family of transcription factors, as highly expressed in murine hearts and other highly oxidative striated muscle beds. Mice bearing cardiac-specific deletion of ESRRß (MHC-ERRB KO) develop DCM and sudden death at ~10 mo of age. Isolated adult cardiomyocytes from the MHC-ERRB KO mice showed an increase in calcium sensitivity and impaired cardiomyocyte contractility, which preceded echocardiographic cardiac remodeling and dysfunction by several months. Histological analyses of myocardial biopsies from patients with various cardiomyopathies revealed that ESRRß protein is absent from the nucleus of cardiomyocytes from patients with DCM but not other forms of cardiomyopathy (ischemic, hypertrophic, and arrhythmogenic right ventricular cardiomyopathy). Taken together these observations suggest that ESRRß is a critical component in the onset of DCM by affecting contractility and calcium balance.NEW & NOTEWORTHY Estrogen-related receptor-ß (ESRRß) is highly expressed in the heart and cardiac-specific deletion results in the development of a dilated cardiomyopathy (DCM). ESRRß is mislocalized in human myocardium samples with DCM, suggesting a possible role for ESRRß in the pathogenesis of DCM in humans.

Diabetes Mellitus with Chronic Complications in Relation to Carotid Endarterectomy and Carotid Artery Stenting Outcomes.

BACKGROUND: Carotid endarterectomy and carotid artery stenting are effective treatment procedures for carotid artery stenosis. Although diabetes mellitus is highly prevalent among patients undergoing these revascularization procedures, few studies have examined their impact on periprocedural outcomes. OBJECTIVES: The study aimed to determine whether perioperative outcomes among patients undergoing carotid artery stenting and carotid endarterectomy varied depending on the presence of diabetes with or without chronic complications. METHODS: We examined adults aged 45 and above hospitalized between 2007 and 2011 in U.S. hospitals who underwent carotid artery revascularization procedures. We used data from the Healthcare Cost and Utilization Project's Nationwide Inpatient Sample and evaluated the influence of diabetes with or without chronic complications on outcomes. RESULTS: Among patients receiving carotid artery stenting, diabetic patients with chronic complications had significantly increased odds of acute kidney injury (odds ratio [OR]: 3.17, 95% confidence interval [CI]: 2.31-4.35) and longer hospital stay (ß: 1.98, 95% CI: 1.58-2.38) compared with nondiabetic patients. Diabetic patients with chronic complications receiving carotid endarterectomy experienced increased odds of myocardial infarction (OR: 1.12, 95% CI: .90-1.40), stroke (OR: 1.29, 95% CI: .97-1.72), perioperative infection (OR: 2.45, 95% CI: 1.29-4.65), mortality (OR: 1.48, 95% CI: 1.01-2.16), and longer hospital stay (ß (days): 2.05, 95% CI: 1.90-2.20) compared with nondiabetic patients. No significant increased odds of perioperative outcomes were observed among diabetic patients without chronic complications. CONCLUSIONS: Uncomplicated diabetes did not appear to convey a higher odds of perioperative outcomes among patients undergoing revascularization. However, the presence of diabetes with chronic complications is an important risk factor in the carotid endarterectomy category.

Correlation Between H-Index, M-Index, and Academic Rank in Urology.

OBJECTIVE: To evaluate the h- and m-indices of academic urologists across all U.S. accredited urology residency programs to determine the relationship between these metrics and an author's academic rank, academic degrees, and gender. METHODS: A total of 136 urology residency programs with available faculty information on their websites were evaluated. The academic rank, academic degrees, and gender were recorded for each clinical and research faculty member. Each author's h-index was determined using the Scopus database. The m-indices for each author were then calculated. Statistical analysis was performed using the Wilcoxon rank-sum test. RESULTS: This study demonstrated that the h- and m-indices positively correlate with an author's academic rank. Among the 2253 academic urologists evaluated, chairs/chiefs and professors had the highest median h- and m-indices (h-index 26, m-index 1.046 for chairs/chiefs; h-index 30, m-index 1.094 for professors). This was followed by associate professors (h-index 14, m-index 0.750), assistant professors (h-index 6, m-index 0.667), and clinical instructors (h-index 6, m-index 0.511). The median h- and m-indices were overall statistically higher for males than females. Faculty members with only a PhD were found to have the highest h- and m-indices followed by MD PhD, MD MBA, MD MPH, MD only, and DO only in descending order of index value. CONCLUSION: The h- and m-indices of academic urologists positively correlate with their academic rank. These metrics may serve as an additional tool in measuring an individual's academic productivity in consideration of job hirings, positional promotions, societal memberships, achievement awards, research grants, and more.

Physician communication behaviors and trust among black and white patients with hypertension.

BACKGROUND: Racial differences in patient trust have been observed, but it is unclear which physician communication behaviors are related to trust, and whether the relationship of communication and trust differs among black and white patients. OBJECTIVE: We sought to determine whether there were associations between physician communication behaviors, visit process measures, and patient trust, particularly within racial groups. METHODS: Study participants included 39 primary care physicians and 227 black and white hypertensive patients from community-based practices in Baltimore, MD. Physician informational and affective communication behaviors and visit process measures were coded from visit audiotapes using the Roter Interaction Analysis System. Patient trust was measured using items from the Trust in Physician Scale, and dichotomized (high/low). Logistic regression analysis using generalized estimating equations was used to assess the association of each physician communication behavior and visit process measure with patient trust, among the entire sample and then stratified by patient race. RESULTS: Positive physician affect and longer visits were significantly associated with high patient trust in unadjusted analyses. After adjustment for covariates, positive physician affect remained a significant predictor of high patient trust in the overall sample (odds ratio 1.26; 95% confidence interval, 1.08, 1.48; P=0.004) and after stratification by race, among black patients (odds ratio 1.35; 95% confidence interval, 1.09, 1.67; P=0.006). CONCLUSIONS: Physician communication behaviors may have a varying effect on patient trust, depending on patient race. Communication skills training programs targeting emotion-handling and rapport-building behaviors are promising strategies to reduce disparities in health care and to enhance trust among ethnic minority patients.

The minimal clinically important difference of the motricity index score.

INTRODUCTION: The Motricity Index (MI) can predict motor function after rehabilitation, but its minimal clinically important difference (MCID) has not been established. The primary study aim was to estimate the MCID value of the MI arm score. METHODS: Between 2017 and 2018, 173 participants hospitalized with confirmed ischemic stroke were recruited into an observational rehabilitation study. Participants with motor weakness as measured by the Fugl-Meyer upper-extremity (FM-UE) and MI with complete baseline and follow-up assessments at 3 months were included in this analysis. The longitudinal recovery of the MI arm score was anchored to having a poor outcome based on the FM-UE recovery (<9) longitudinally. Results reported include the area-under-curve (AUC), along with sensitivity, specificity, and optimal cut-points based on maximizing the Youden statistic. RESULTS: Sixty-nine patients (median [IQR] age 70 [18] years; 48% male; 54% white) were included in the final analysis. Mean ± standard deviation outcome scores at 3-months were: MI arm: 83.19 ± 22.80; FM-UE: 53.04 ± 17.26. For the primary results, the MI arm score optimal MCID cutoff for observed recovery was 13 points with a sensitivity of 80% (95% Confidence Interval (CI)(67.6%, 92.4%)) and a specificity of 69.0% (95% CI (52.1, 85.8%)), and the AUC was 0.8082 (0.7007, 0.9157). CONCLUSIONS: This was the first study to report the MCID of the MI arm score, as anchored to the FM-UE recovery between acute evaluation and 3-months. The estimated optimal MCID of improvement in the MI arm score was 13 points.
