ABSTRACT
PURPOSE: Though the pathogenesis of benign prostatic hyperplasia is unclear, it was previously believed that increasing androgen levels contributed, though not all data support this idea. We tested if elevated serum testosterone or dihydrotestosterone were risk factors for lower urinary tract symptoms incidence in asymptomatic men and for lower urinary tract symptoms progression in symptomatic men. MATERIALS AND METHODS: A post hoc analysis of REDUCE was performed in 3009 asymptomatic men and in 2145 symptomatic men. REDUCE was a randomized trial of dutasteride for prostate cancer prevention in men with an elevated prostate-specific antigen and negative prestudy biopsy. We estimated multivariable adjusted hazard ratios and 95% confidence intervals using Cox models to test the association between quintiles of serum testosterone and dihydrotestosterone at baseline and lower urinary tract symptoms incidence and progression and tested for interaction by treatment arm (dutasteride vs placebo). RESULTS: In asymptomatic men, there was no evidence serum testosterone or dihydrotestosterone were related to lower urinary tract symptoms incidence (P = .9, P = .4). In symptomatic men, there was no evidence serum testosterone or dihydrotestosterone were related to lower urinary tract symptoms progression (P = .9, P = .7). Results were similar in both placebo and dutasteride arms (all P interaction ≥ .3). CONCLUSIONS: In REDUCE, higher serum testosterone and higher serum dihydrotestosterone were not associated with either lower urinary tract symptoms incidence in asymptomatic men or lower urinary tract symptoms progression in symptomatic men. These data do not support the hypothesis that serum androgens in middle-aged men are associated with lower urinary tract symptoms.

Antibody-mediated rejection (AMR) is the major cause of graft loss in kidney transplant recipients. The Banff classification defines two classes of AMR, active and chronic active but over time this classification has become increasingly complex. To simplify the approach to AMR, we developed activity and chronicity indices based on kidney transplant biopsy findings and examined their association with graft survival in 147 patients with active or chronic active AMR, all of whom had donor-specific antibodies and were treated for AMR. The activity index was determined as the sum of Banff glomerulitis (g), peritubular capillaritis (ptc), arteritis (v) and C4d scores, with a maximum score of 12. The chronicity index was the sum of interstitial fibrosis (ci), tubular atrophy (ct), chronic vasculopathy (cv), and chronic glomerulopathy (cg) scores, the latter doubled, with a maximum score of 15. While the activity index was generally not associated with graft loss, the chronicity index was significantly associated with graft loss with an optimal threshold value of 4 or greater for predicting graft loss. The association of the chronicity index of 4 or greater with graft loss was independent of other parameters associated with graft loss, including the estimated glomerular filtration rate at the time of biopsy, chronic active (versus active) AMR, AMR with de novo (versus persistent/rebound) donor-specific antibodies, Banff (g+ptc) scores, concurrent T cell-mediated rejection and donor-specific antibody reduction post-biopsy. The association of the chronicity index of 4 or greater with graft loss was confirmed in an independent cohort of 61 patients from Necker Hospital, Paris. Thus, our findings suggest that the chronicity index may be valuable as a simplified approach to decision-making in patients with AMR.

BACKGROUND: Noninvasive telemonitoring and nurse telephone coaching (NTM-NTC) is a promising postdischarge strategy in heart failure (HF). Comorbid conditions and disease burden influence health outcomes in HF, but how comorbidity burden modulates the effectiveness of NTM-NTC is unknown. This study aims to identify patients with HF who may benefit from postdischarge NTM-NTC based on their burden of comorbidity. METHODS AND RESULTS: In the Better Effectiveness After Transition - Heart Failure trial, patients hospitalized for acute decompensated HF were randomized to postdischarge NTM-NTC or usual care. In this secondary analysis of 1313 patients with complete data, comorbidity burden was assessed by scoring complication and coexisting diagnoses from index admissions. Clinical outcomes included 30-day and 180-day readmissions, mortality, days alive, and combined days alive and out of the hospital. Patients had a mean of 5.7 comorbidities and were stratified into low (0-2), moderate (3-8), and high comorbidity (≥9) subgroups. Increased comorbidity burden was associated with worse outcomes. NTM-NTC was not associated with readmission rates in any comorbidity subgroup. Among high comorbidity patients, NTM-NTC was associated with significantly lower mortality at 30 days (hazard ratio 0.25, 95% confidence interval 0.07-0.90) and 180 days (hazard ratio 0.51, 95% confidence interval 0.27-0.98), as well as more days alive (160.1 vs 140.3, Pâ¯=â¯.029) and days alive out of the hospital (152.0 vs 133.2, Pâ¯=â¯.044) compared with usual care. CONCLUSIONS: Postdischarge NTM-NTC improved survival among patients with HF with a high comorbidity burden. Comorbidity burden may be useful for identifying patients likely to benefit from this management strategy.

BACKGROUND: Perinatal mood and anxiety disorders encompass a range of mental health disorders that occur during pregnancy and up to 1 year postpartum, affecting approximately 20% of women. Traditional risk factors, such as a history of depression and pregnancy complications including preeclampsia, are known. Their predictive utility, however, is not specific or sensitive enough to inform clinical decision-making or prevention strategies for perinatal mood and anxiety disorders. Better diagnostic and prognostic models are needed for early identification and referral to treatment. OBJECTIVE: This study aimed to determine if a panel of novel third-trimester plasma protein biomarkers in pregnant women can be used to identify those who have a high predisposed risk for perinatal mood and anxiety disorders within 3 months postpartum. STUDY DESIGN: We studied 52 women (n=34 with a risk for perinatal mood and anxiety disorders and n=18 controls) among whom mental health screening was conducted at 2 time points, namely in the third trimester and again at 3 months postdelivery. An elevated perinatal mood and anxiety disorder risk was identified by screening individuals with above-validated cutoffs for depression (Edinburgh Postnatal Depression Scale ≥12), anxiety (Overall Anxiety Severity and Impairment Scale ≥7), and/or posttraumatic stress disorder (Impact of Events Scale >26) at both time points. Plasma samples collected in the third trimester were screened using the aptamer-based SomaLogic SomaScan proteomic assay technology to evaluate perinatal mood and anxiety disorder-associated changes in the expression of 1305 protein analytes. Ingenuity Pathway Analysis was conducted to highlight pathophysiological relationships between perinatal mood and anxiety disorder-specific proteins found to be significantly up- or down-regulated in all subjects with perinatal mood and anxiety disorder and in those with perinatal mood and anxiety disorders and no preeclampsia. RESULTS: From a panel of 53 significant perinatal mood and anxiety disorder-associated proteins, a unique 20-protein signature differentiated perinatal mood and anxiety disorder cases from controls in a principal component analysis (P<.05). This protein signature included NCAM1, NRCAM, and NTRK3 that converge around neuronal signaling pathways regulating axonal guidance, astrocyte differentiation, and maintenance of GABAergic neurons. Interestingly, when we restricted the analysis to subjects without preeclampsia, a 30-protein signature differentiated perinatal mood and anxiety disorder cases from all controls without overlap on the principal component analysis (P<.001). In the nonpreeclamptic perinatal mood and anxiety disorder group, we observed increased expression of proteins, such as CXCL11, CXCL6, MIC-B, and B2MG, which regulate leucocyte migration, inflammation, and immune function. CONCLUSION: Participants with perinatal mood and anxiety disorders had a unique and distinct plasma protein signature that regulated a variety of neuronal signaling and proinflammatory pathways. Additional validation studies with larger sample sizes are needed to determine whether some of these molecules can be used in conjunction with traditional risk factors for the early detection of perinatal mood and anxiety disorders.

BACKGROUND: A subset of chronic anal fissures beget focal infection, leading to concomitant fistula. The optimal management of fissure-associated fistula is unknown. OBJECTIVE: This study aimed to characterize healing rates and effects of fistulotomy in fissure-associated fistula. DESIGN: Retrospective study. SETTING: Urban tertiary center. PATIENTS: Adults who underwent fistulotomy for a fistula associated with a chronic anal fissure were included in the study. However, those with Crohn's disease, a history of lateral internal sphincterotomy, and a fistula not amenable to fistulotomy were excluded. INTERVENTIONS: Patients were managed with fistulotomy. Fissures were otherwise managed conservatively with a step-up approach. MAIN OUTCOME MEASURES: The primary end point was healing, defined as resolution of symptoms and both fistula and fissure wounds within 1 year. Subgroup analysis compared those who underwent subcutaneous fistulotomy (group A) with those who underwent fistulotomy involving anal sphincter fibers (group B). RESULTS: Twenty-four of 38 patients (63%) healed with a median overall follow-up of 6.6 months (4.2-14.1). The overall median time to healing was 4.4 months (2.2-6.0). No clinical or pathologic factors predicted healing. In subgroup analysis, overall subcutaneous fistulotomy healing rates were nonstatically lower at 46% (6/13) compared to fistulotomy involving anal sphincter fibers at 72% (18/25; p = 0.16). There was no difference in time to healing (subcutaneous fistulotomy, 6.7 mo [5.2-8.4] vs fistulotomy involving sphincter, 5.1 mo [2.1-7.0]; p = 0.36). LIMITATIONS: The limitations include treatment bias, with increased utilization of chemical sphincter-relaxing agents in those who did not heal. Findings are not applicable to complex fistulas, Crohn's disease, or atypical fissures. CONCLUSIONS: Patients presenting with chronic fissure and associated subcutaneous, intersphincteric, or low transphincteric fistula are successfully managed with fistulotomy. Patients with a subcutaneous fistula tract exhibited nonstatistically significantly lower rates of healing. See Video Abstract at http://links.lww.com/DCR/C145 . EFICACIA DE LA DIVISIN ESFINTRICA DURANTE LA FISTULOTOMA EN CASOS DE FSTULA ASOCIADA A FISURA ANAL: ANTECEDENTES: Ciertos subgrupos de fisuras anales crónicas ocasionan infección localizada, induciendo la aparición de una fístula anal concomitante. Se desconoce el manejo óptimo de la fístula concomitante a una fisura anal.OBJETIVO: Se trata de caracterizar las tasas de curación y el efecto de la fistulotomía en el tratamiento de la fístula concomitante a la fisura anal.DISEÑO: Estudio retrospectivo.EMPLAZAMIENTO: Centro terciario urbano.PACIENTES: Adultos sometidos a fistulotomía por una fístula concomitante a una fisura anal crónica. Se excluyeron la enfermedad de Crohn, el antecedente de una esfinterotomía lateral interna y las fístulas no susceptibles de fistulotomía.INTERVENCIONES: Los pacientes fueron manejados con una fistulotomía clasica. Por lo demás, las fisuras se trataron de forma conservadora con un enfoque médico escalonado.PRINCIPALES MEDIDAS DE RESULTADO: El criterio principal de valoración fué la cura definitiva, determinada como la resolución completa de los síntomas y de las heridas tanto de la fístula como de la fisura en el plazo de un año. El análisis de los subgrupos comparó los que se sometieron a una fistulotomía subcutánea (grupo A) versus una fistulotomía que involucró las fibras del esfínter anal interno (grupo B).RESULTADOS: 24/38 pacientes (63%) curaron con una mediana de seguimiento global de 6,6 meses (4,2-14,1). El tiempo medio general de curación fue de 4,4 meses (2,2-6,0). Ningún factor clínico o patológico predijo la cura. En el análisis de subgrupos, las tasas generales de cura de la fistulotomía subcutánea no fueron estadísticamente más bajas de 46 % (6/13) comparados con la fistulotomía que involucró las fibras del esfínter anal interno en 72 % (18/25; p = 0,16). No hubo diferencia en el tiempo de cicatrización [fistulotomía subcutánea 6,7 meses (5,2-8,4) conparada a la fistulotomía y esfínterotomía parcial interna a 5,1 meses (2,1-7,0); p = 0,36].LIMITACIONES: Sesgo del tratamiento, con mayor utilización de agentes químicos relajantes de la musculatura esfínteriana en aquellos pacientes que no sanaron. No aplicable a fístulas complejas, enfermedad de Crohn o fisuras atípicas.CONCLUSIÓNES: Los pacientes que presentan fisura crónica y fístula subcutánea, inter-esfintérica o trans-esfintérica baja concomitante se manejan con éxito con una fistulotomía. Los pacientes con un trayecto de fístula subcutánea exhibieron tasas de curación más bajas y no estadísticamente significativas. Consulte Video Resumen en http://links.lww.com/DCR/C145 .

BACKGROUND: Physical restraints are used in the emergency department (ED) for agitated patients to prevent self-harm and protect staff. Prior studies identified associations between sociodemographic factors and ED physical restraints use. OBJECTIVES: The primary objective was to compare characteristics of ED patients receiving physical restraints for violent and nonviolent indications vs. patients who were not restrained. The secondary objective was to compare rates of restraint use among ED providers. METHODS: This was a single-center cross-sectional study of adult ED patients from March 2019 to February 2021. Factors compared across groups were age over 50 years, gender, race, ethnicity, insurance, housing, primary language, Emergency Severity Index, time of arrival, mode of arrival, chief complaint, and medical admission. Odds ratios were reported. Rates of emergency physician restraint orders were compared using the chi-square test. RESULTS: Restraints were used in 1228 (0.9%) visits. Younger age, male gender, "unknown" ethnicity, self-pay or "other" nonprivate insurance, homelessness, arrival by first responders, and medical hospitalization were associated with increased odds of restraint. Black patients had lower odds of any restraint than White patients (odds ratio 0.93; 95% confidence interval 0.79-1.09) and higher odds of violent restraint than White patients, although not significant (odds ratio 1.55; 95% confidence interval 0.95-2.54). ED providers had significant differences in total and violent restraint use (p-values < 0.0001 and 0.0003, respectively). CONCLUSION: At this institution, certain sociodemographic characteristics were associated with receiving both types of physical restraint. Emergency physicians also differed in restraint-ordering practice. Further investigation is needed to understand the influence of implicit bias on ED restraint use.
ABSTRACT
BACKGROUND: Total proctocolectomy with ileal pouch-anal anastomosis has become the standard procedure for patients with medically refractory ulcerative colitis, although a subset will develop de novo Crohn's disease. OBJECTIVE: In this study, we investigated the association of preoperative C-reactive protein levels with the development of de novo Crohn's disease after ileal pouch-anal anastomosis. DESIGN: A prospectively maintained database of patients undergoing ileal pouch-anal anastomosis was reviewed. PATIENTS: Preoperative C-reactive protein levels were compared between patients who developed de novo Crohn's disease and those who did not. De novo Crohn's disease was defined as small-bowel inflammation proximal to the ileal pouch or perianal disease identified more than 3 months after ileostomy closure. To minimize the heterogeneity of the timing of preoperative C-reactive protein measurement and the severity of ulcerative colitis, only hospitalized patients who had proctocolectomy for severe ulcerative colitis were included in the study. MAIN OUTCOME MEASURES: Development of de novo Crohn's disease was analyzed. RESULTS: Of 105 patients, 23 (22%) developed de novo Crohn's disease. Having C-reactive protein in the third tertile significantly increased the risk of developing de novo Crohn's disease (HR 3.44, 95% CI 1.10- 10.70, p = 0.03) compared to in the first tertile. In a multivariable model, a C-reactive protein in the third or second tertile vs the first tertile and younger age was associated with the development of de novo Crohn's disease. LIMITATIONS: Limited to only hospitalized patients with severe ulcerative colitis. CONCLUSIONS: In hospitalized patients undergoing ileal pouch-anal anastomosis for medically refractory ulcerative colitis, higher preoperative C-reactive protein levels appear to increase the risk of developing de novo Crohn's disease.

La enfermedad de Crohn de novo se definió como una inflamación del intestino delgado proximal a la bolsa ileal o una enfermedad perianal identificada más de 3 meses después del cierre de la ileostomía. Para minimizar la heterogeneidad del momento de la medición de la proteína C reactiva preoperatoria y la gravedad de la colitis ulcerativa, solo se incluyeron en el estudio los pacientes hospitalizados que se sometieron a una proctocolectomía por colitis ulcerativa grave.PRINCIPALES MEDIDAS DE RESULTADO:se analizó el desarrollo de la enfermedad de Crohn de novo.RESULTADOS:De 105 pacientes, 23 (22%) desarrollaron enfermedad de Crohn de novo. Tener una proteína C reactiva en el tercer tercil aumentó significativamente el riesgo de desarrollar la enfermedad de Crohn de novo (HR 3,44, IC del 95%: 1,10-10,70, p = 0,03) en comparación con el primer tercil. En un modelo multivariable, una proteína C reactiva en el tercer o segundo tercil frente al primer tercil y una edad más joven se asoció con el desarrollo de la enfermedad de Crohn de novo.LIMITACIONES:Limitado solo a pacientes hospitalizados con colitis ulcerativa grave.CONCLUSIONES:En pacientes hospitalizados sometidos a anastomosis bolsa ileal-anal por colitis ulcerativa refractaria al tratamiento médico, niveles más elevados de proteína C reactiva preoperatoria parecen aumentar el riesgo de desarrollar enfermedad de Crohn de novo.

BACKGROUND: The role of angiotensin II type 1 receptor antibodies (AT1R-Ab) in pediatric renal transplantation is unclear. Here, we evaluated pre-transplant AT1R-Ab on transplant outcomes in the first 5 years. Secondary analysis compared pre-transplant AT1R-Ab levels by age. METHODS: Thirty-six patients, 2-20 years old, were divided into two groups: pre-transplant AT1R-Ab- (<17 U/ml; n = 18) and pre-transplant AT1R-Ab+ (≥17 U/ml; n = 18). eGFR was determined at 6-month, 1-, 2-, and 4-year post-transplant. Allograft biopsies were performed in the setting of strong HLA-DSA (MFI > 10 000), AT1R-Ab ≥17 U/ml, and/or elevated creatinine. RESULTS: Mean age in pre-transplant AT1R-Ab- was 13.3 years vs. 11.0 in pre-transplant AT1R-Ab+ (p = 0.16). At 6 months, mean eGFR was 111.3 ml/min/1.73 m2 in pre-transplant AT1R-Ab- vs. 100.2 in pre-transplant AT1R-Ab + at 1 year, 103.6 ml/min/1.73 m2 vs. 100.5; at 2 years, 98.9 ml/min/1.73 m2 vs. and 93.7; at 4 years, 72.6 ml/min/1.73 m2 vs. 80.9. 11/36 patients had acute rejection (6 in pre-transplant AT1R-Ab-, 5 in pre-transplant AT1R-Ab + ). There was no difference in rejection rates. All 6 subjects with de novo HLA-DSA and AT1R-Ab ≥17 U/ml at the time of biopsy experienced rejection. Mean age in those with the AT1R-Ab ≥40 U/ml was 10.0 years vs. 13.2 in those <40 U/ml (p = 0.07). CONCLUSION: In our small cohort, pre-transplant AT1R-Ab ≥17 U/ml was not associated with reduced graft function or rejection. The pathogenicity of pre-transplant AT1R-Ab in pediatric kidney transplantation requires further investigation.

AIMS: To gather the best available evidence regarding Ki-67% values in large-cell neuroendocrine carcinoma (LCNEC) and determine whether certain cut-off values could serve as a prognostic feature in LCNEC. METHODS AND RESULTS: Aperio ScanScope AT Turbo, eSlide Manager and ImageScope software (Leica Biosystems) were used to measure Ki-67% in 77 resected LCNEC diagnosed by World Health Organisation (WHO) criteria. Cases were stratified into six classes by 10% Ki-67 increments. Using the Kaplan-Meier method, overall (OS) and disease-free survivals (DFS) were compared by AJCC stage, by six Ki-67% classes and with Ki-67% cut-points ≥20% and ≥40%. Tumours were from 0.9 to 11.5 cm and pathological stages 1-3. The system measured Ki-67% positivity using 4072-44 533 tumour nuclei per case (mean 16610 ± 8039). Ki-67% ranged from 1 to 64% (mean = 26%; median = 26%). Only 16 (21%) tumours had Ki-67% ≥40%. OS ranged from 1 to 298 months (median follow-up = 25 months). DFS ranged from 1 to 276 months (median follow-up = 9 months). OS and DFS differed across AJCC stage (overall log-rank P = 0.038 and P = 0.037). However, neither OS nor DFS significantly correlated with Ki-67% when six or two classes were used with either ≥20% Ki-67 or ≥40% Ki-67 as cut-point. A literature review identified 14 reports meeting our inclusion criteria with ≥10 LCNEC. Reported Ki-67% ranged from 2% to 100%. Problems contributing to variability in Ki-67% measurements are discussed. CONCLUSION: Our findings caution against a blanket use of 20%, 40% or other Ki-67% cut-points for LCNEC diagnosis or prognostication.

BACKGROUND: Some renal biopsies cannot distinguish minimal change disease (MCD) from primary focal segmental glomerulosclerosis (FSGS) because of inadequate sampling and/or a lack of sampled glomeruli with segmental sclerosis. As protein excretion in MCD has been described as being albumin-selective, we examined whether the ratio of immunoglobulin G (IgG)/albumin staining in protein reabsorption droplets (tPRD) might help distinguish MCD from FSGS. METHODS: Frozen tissue from 144 native renal biopsies from patients with nephrotic syndrome and a diagnosis of MCD or FSGS [73 MCD, 30 FSGS tip variant (FSGS-tip), 38 FSGS-not otherwise specified (FSGS-NOS), 3 FSGS collapsing] was retrospectively stained by direct immunofluorescence for IgG and albumin; none of these samples showed diagnostic lesions of FSGS. IgG and albumin staining of tPRD were graded on a scale of 0 to 3+ based on the distribution and intensity of staining. RESULTS: Mean (standard deviation) IgG/albumin staining ratios were 0.186 ± 0.239 for MCD, 0.423 ± 0.334 for FSGS-tip (P = 0.0001 versus MCD) and 0.693 ± 0.297 for FSGS-NOS (P < 0.0001 versus MCD; P = 0.0001 versus FSGS-tip). Of 84 biopsies with a ratio ≤0.33, 63 (75%) showed MCD, whereas among 21 with a ratio of 1.0, all but one showed FSGS (15 FSGS-NOS). CONCLUSIONS: In summary, IgG/albumin staining in tPRD was correlated with histologic diagnosis in renal biopsies with MCD and FSGS. A ratio of ≤0.33 was associated with MCD, whereas a ratio of 1.0 was most often seen with FSGS-NOS.

BACKGROUND: Transversus abdominis plane blocks are increasingly used to achieve opioid-sparing analgesia after colorectal surgery. Traditionally, bupivacaine was the long-acting analgesic of choice, but the addition of dexamethasone and/or epinephrine to bupivacaine may extend block duration. Liposomal bupivacaine has also been suggested to achieve an extended analgesia duration of 72 hours but is significantly more expensive. OBJECTIVE: The purpose of this study was to compare pain control between laparoscopic transversus abdominis plane blocks using liposomal bupivacaine versus bupivacaine with epinephrine and dexamethasone. DESIGN: This was a parallel-group, single-institution, randomized clinical trial. SETTINGS: The study was conducted at a single tertiary medical center. PATIENTS: Consecutive patients between October 2018 to October 2019, ages 18 to 90 years, undergoing minimally invasive colorectal surgery with multimodal analgesia were included. INTERVENTIONS: Patients were randomly assigned 1:1 to receive a laparoscopic transversus abdominis plane block with liposomal bupivacaine or bupivacaine with epinephrine and dexamethasone. MAIN OUTCOME MEASURES: The primary outcome was total oral morphine equivalents administered in the first 48 hours postoperatively. Secondary outcomes included pain scores, time to ambulation and solid diet, hospital length of stay, and complications. RESULTS: A total of 102 patients (50 men) with a median age of 42 years (interquartile range, 29-60 y) consented and were randomly assigned. The primary end point, total oral morphine equivalents administered in the first 48 hours, was not significantly different between the liposomal bupivacaine group (median = 69 mg) and the bupivacaine with epinephrine and dexamethasone group (median = 47 mg; difference in medians = 22 mg, (95% CI, -17 to 49 mg); p = 0.60). There were no significant differences in pain scores, time to ambulation, time to diet tolerance, time to bowel movement, length of stay, overall complications, or readmission rate between groups. There were no treatment-related adverse outcomes. LIMITATIONS: This study was not placebo controlled or blinded. CONCLUSIONS: This first randomized trial comparing laparoscopic transversus abdominis plane block with liposomal bupivacaine or bupivacaine with epinephrine and dexamethasone showed that a liposomal bupivacaine block does not provide superior or extended analgesia in the era of standardized multimodal analgesia protocols.See Video Abstract at http://links.lww.com/DCR/B533. ESTUDIO PROSPECTIVO Y RANDOMIZADO DE BLOQUEO DEL PLANO MUSCULAR TRANSVERSO DEL ABDOMEN REALIZADO POR EL CIRUJANO CON BUPIVACANA VERSUS BUPIVACANA LIPOSOMAL ESTUDIO TINGLE: ANTECEDENTES:El bloqueo anestésico del plano muscular transverso del abdomen se utiliza cada vez más para lograr una analgesia con menos consumo de opioides después de cirugía colorrectal. Tradicionalmente, la Bupivacaína era el analgésico de acción prolongada de elección, pero al agregarse Dexametasona y/o Adrenalina a la Bupivacaína se puede prolongar la duración del bloqueo. También se ha propuesto que la Bupivacaína liposomal logra una duración prolongada de la analgesia de 72 horas, pero es significativamente más cara.OBJETIVO:Comparar el control del dolor entre bloqueo laparoscópico del plano de los transversos del abdomen usando Bupivacaína liposomal versus Bupivacaína con Adrenalina y Dexametasona.DISEÑO:Estudio clínico prospectivo y randomizado de una sola institución en grupos paralelos.AJUSTE:Centro médico terciario único.PACIENTES:Todos aquellos pacientes entre 18 y 90 años sometidos a cirugía colorrectal mínimamente invasiva con analgesia multimodal, entre octubre de 2018 a octubre de 2019 incluidos de manera consecutiva.INTERVENCIONES:Los pacientes fueron seleccionados aleatoriamente 1:1 para recibir un bloqueo laparoscópico del plano de los transversos del abdomen con Bupivacaína liposomal o Bupivacaína con Adrenalina y Dexametasona.PRINCIPALES MEDIDAS DE RESULTADO:El resultado primario fue el total de equivalentes de morfina oral administradas en las primeras 48 horas después de la operación. Los resultados secundarios incluyeron puntuaciones de dolor, inicio de dieta sólida, tiempo de inicio a la deambulación, la estadía hospitalaria y las complicaciones.RESULTADOS:Un total de 102 pacientes (50 hombres) con una mediana de edad de 42 años (IQR 29-60) fueron incluidos aleatoriamente. El criterio de valoración principal, equivalentes de morfina oral total administrada en las primeras 48 horas, no fue significativamente diferente entre el grupo de Bupivacaína liposomal (mediana = 69 mg) y el grupo de Bupivacaína con Adrenalina y Dexametasona (mediana = 47 mg; diferencia en medianas = 22 mg, IC del 95% [-17] - 49 mg, p = 0,60). No hubo diferencias significativas en las puntuaciones de dolor, tiempo de inicio a la deambulación, el tiempo de tolerancia a la dieta sólida, el tiempo hasta el primer evacuado intestinal, la duración de la estadía hospitalaria, las complicaciones generales o la tasa de readmisión entre los grupos.

OBJECTIVE: To describe the impact of COVID-19 on acute cerebrovascular disease care across 9 comprehensive stroke centers throughout Los Angeles County (LAC). METHODS: Volume of emergency stroke code activations, patient characteristics, stroke severity, reperfusion rates, treatment times, and outcomes from February 1 to April 30, 2020, were compared against the same time period in 2019. Demographic data were provided by each participating institution. RESULTS: There was a 17.3% decrease in stroke code activations across LAC in 2020 compared to 2019 (1,786 vs. 2,159, respectively, χ2 goodness of fit test p < 0.0001) across 9 participating comprehensive stroke centers. Patients who did not receive any reperfusion therapy decreased by 16.6% in 2020 (1,527) compared to 2019 (1,832). Patients who received only intravenous thrombolytic (IVT) therapy decreased by 31.8% (107 vs. 157). Patients who received only mechanical thrombectomy (MT) increased by 3% (102 vs. 99). Patients who received both IVT and MT decreased by 31.8% (45 vs. 66). Recanalization treatment times in 2020 were comparable to 2019. CSCs serving a higher proportion of Latinx populations in the eastern parts of LAC experienced a higher incidence of MT in 2020 compared to 2019. Mild increase in stroke severity was seen in 2020 compared to 2019 (8.95 vs. 8.23, p = 0.046). A higher percentage of patients were discharged home in 2020 compared to 2019 (59.5 vs. 56.1%, p = 0.034), a lower percentage of patients were discharged to skilled nursing facility (16.1 vs. 20.7%, p = 0.0004), and a higher percentage of patients expired (8.6 vs. 6.3%, p = 0.008). CONCLUSION: LAC saw a decrease in overall stroke code activations in 2020 compared to 2019. Reperfusion treatment times remained comparable to prepandemic metrics. There has been an increase in severe stroke incidence and higher volume of thrombectomy treatments in Latinx communities within LAC during the pandemic of 2020. More patients were discharged home, less patients discharged to skilled nursing facilities, and more patients expired in 2020, compared to the same time frame in 2019.

AIM: Tumour necrosis factor inhibitors (TNFi) have revolutionized the management of moderate to severe ulcerative colitis (UC) since their approval for UC in 2005. However, many patients ultimately require surgery with ileal pouch-anal anastomosis (IPAA). Development of de novo Crohn's disease (CD) following IPAA is an increasingly common and devastating complication, sometimes progressing to pouch failure. The aim of this study was to evaluate the association of preoperative TNFi exposure and the development of de novo CD after IPAA. METHOD: A prospective single-centre inflammatory bowel disease (IBD) registry was searched for consecutive patients with UC undergoing IPAA during a 25-year period ending July 2018. Patients with preoperative CD or IBD-unclassified were excluded. De novo CD was diagnosed upon endoscopic evidence of five or more mucosal ulcers proximal to the ileal pouch any time after surgery and/or pouch fistula occurring more than three months after ileostomy closure. RESULTS: The study cohort consisted of 400 patients with a median follow-up of 44.0 (IQR 11-113) months. Sixty-two (16%) patients developed de novo CD 28.0 (IQR 6-67) months following ileostomy closure. Survival analysis of TNFi era patients revealed a significant increase in de novo CD risk in those with preoperative TNFi exposure. Multivariable proportional hazards modelling revealed two independent predictors for de novo CD development: older age was protective (HR 0.89 per 5-year increase; P = 0.009) and preoperative TNFi exposure was hazardous (HR 2.10; P = 0.011). CONCLUSION: This prospective study is the first to suggest an association between preoperative TNFi exposure and the development of de novo CD.

The aim of this study is to characterize and compare changes in gene expression patterns of paired axillary lymph node (ALN) metastases from estrogen receptor (ER)-positive and triple-negative (TNBC) primary breast cancer (PBC). Patients with stage 2-3 PBC with macrometastasis to an ALN were selected. Gene expression of 2567 cancer-associated genes was analyzed with the HTG EdgeSeq system coupled with the Illumina Next Generation Sequencing (NGS) platform. Changes in gene expression between ER/PR-positive, HER2-negative PBC, and their paired ALN metastases were compared with TNBC and their paired ALN metastases. Fourteen pairs of ER-positive and paired ALN metastasis were analyzed. Compared with the PBC, ALN metastasis had 673 significant differentially expressed genes, including 348 upregulated genes and 325 downregulated genes. Seventeen pairs of TNBC and paired ALN metastasis were analyzed. ALN metastasis had 257 significant differentially expressed genes, including 123 upregulated genes and 134 downregulated genes. When gene expression of the ALN for ER-positive PBC was compared to that of TNBC, 97 genes were upregulated in both, and 115 genes were similarly downregulated. Common upregulated genes were associated with cell death, necrosis, and homeostasis. Common downregulated genes were those of migration, degradation of extracellular matrix, and invasion. Although ER-positive PBC and TNBC have a distinct gene expression profiles and distinct changes from PBC to ALN metastases, a significant number of genes are similarly up- or downregulated. Understanding the role of these common genomic changes may provide clues to understanding the metastatic process itself.

The COVID-19 pandemic has significantly impacted the service delivery model (SDM) of clinical genetic counseling across the United States and Canada. A cross-sectional survey was distributed to 4,956 genetic counselors (GCs) from the American Board of Genetic Counselors and Canadian Association of Genetic Counselors mailing lists in August 2020 to assess the change in utilization of telehealth for clinical genetic counseling during the COVID-19 pandemic compared with prior to the pandemic. Data from 411 eligible clinical genetic counselors on GC attitudes and their experiences prior to and during the pandemic were collected and analyzed to explore the change in SDM, change in appointment characteristics, change in billing practices, GC perceived benefits and limitations of telehealth, and prediction of future trends in SDM in the post-pandemic era. The study showed the overall utilization of audiovisual and telephone encounters increased by 43.4% and 26.2%, respectively. The majority of respondents who provided audiovisual and telephone encounters reported increased patient volume compared with prior to the pandemic, with an average increase of 79.4% and 42.8%, respectively. There was an increase of 69.4% of GCs rendering genetic services from home offices. The percentage of participants who billed for telehealth services increased from 45.7% before the pandemic to 80.3% during the pandemic. The top GC perceived benefits of telehealth included safety for high-risk COVID patients (95.2%) and saved commute time for patients (94.7%). The top GC perceived limitations of telehealth included difficulty to conduct physician evaluation/coordinating with healthcare providers (HCP) (73.7%) and difficulty addressing non-English speaking patients (68.5%). Overall, 89.6% of GCs were satisfied with telehealth; however, 55.3% reported uncertainty whether the newly adopted SDM would continue after the pandemic subsides. Results from this study demonstrate the rapid adoption of telehealth for clinical genetic counseling services as a result of the COVID-19 pandemic, an increase in billing for these services, and support the feasibility of telehealth for genetic counseling as a longer term solution to reach patients who are geographically distant.

BACKGROUND: Patient Satisfaction (PS) is a commonly used metric in health care settings to assess the quality of care given by physicians. Monitoring physicians in this way may impact physician quality of life. Studies evaluating this impact are not available. This study sought to examine the physician experience of measuring PS among practicing otolaryngologists. METHODS: Using an online survey platform, a 34-item survey was given to practicing otolaryngologists through email distribution. The survey included questions about physician, practice and patient demographics, as well as inquiries regarding the way in which PS was measured and how it affected physician work and personal life. Data from these questions were reviewed and analyzed. RESULTS: 174 otolaryngologists responded to the survey. A majority of physicians' (55.3%) PS scores had been tracked with 89.9% reporting being tracked for a length of at least 1 year. PS scores for individual physicians were noted to be inconsistent and vary significantly between reports. Measuring patient satisfaction led to increased occupational stress, yet most physicians (63.8%) felt the monitoring did not lead to improvements in their practice. Some physicians (36.2%) reported that the collection of patient satisfaction scores had negatively influenced the way they practiced medicine, including the pressure to order superfluous tests or to prescribe unnecessary medications. CONCLUSION: Overall, physicians are negatively affected by the tracking of patient satisfaction scores. Occupational stress caused by the collection of patient satisfaction scores may contribute to physician burnout.

Donor-derived cell-free DNA (dd-cfDNA) became Medicare reimbursable in the United States in October 2017 for the detection of rejection in kidney transplant recipients based on results from its pivotal validation trial, but it has not yet been externally validated. We assessed 63 adult kidney transplant recipients with suspicion of rejection with dd-cfDNA and allograft biopsy. Of these, 27 (43%) patients had donor-specific antibodies and 34 (54%) were found to have rejection by biopsy. The percentage of dd-cfDNA was higher among patients with antibody-mediated rejection (ABMR; median 1.35%; interquartile range [IQR]: 1.10%-1.90%) compared to those with no rejection (median 0.38%, IQR: 0.26%-1.10%; P < .001) and cell-mediated rejection (CMR; median: 0.27%, IQR: 0.19%-1.30%; P = .01). The dd-cfDNA test did not discriminate patients with CMR from those without rejection. The area under the ROC curve (AUC) for CMR was 0.42 (95% CI: 0.17-0.66). For ABMR, the AUC was 0.82 (95% CI: 0.71-0.93) and a dd-cfDNA ≥0.74% yielded a sensitivity of 100%, specificity 71.8%, PPV 68.6%, and NPV 100%. The dd-cfDNA test did not discriminate CMR from no rejection among kidney transplant recipients, although performance characteristics were stronger for the discrimination of ABMR.

RATIONALE & OBJECTIVE: Increased access to transplantation for highly sensitized candidates following implementation of the kidney allocation system (KAS) has been mostly due to higher use of organs with a lower kidney donor profile index (KDPI; a quality metric for donated kidneys), although changes in allocation of these organs was not intended. It is unclear whether clinical outcomes have changed in association with these changes. We investigated the use of kidneys with low and high KDPI scores over time and whether KDPI score affects patient and graft survival differently across varying levels of allosensitization. STUDY DESIGN: Observational cohort study. SETTING & PARTICIPANTS: Adult (aged ≥18 years) recipients of a deceased donor kidney transplant between October 1, 2009, and September 30, 2017 (Organ Procurement and Transplantation Network/United Network for Organ Sharing database; n = 84,451). PREDICTORS: Calculated panel-reactive antibody (cPRA) level (0%, 1%-79%, 80%-89%, 90%-98%, and 99%-100%) and KDPI score (≤20%, 21%-85%, and >85%). OUTCOMES: Death, graft loss. ANALYTICAL APPROACH: Time to event. RESULTS: Allocation of kidneys with KDPI scores ≤ 20% and KDPI scores of 21% to 85% to recipients with cPRA levels ≥ 99% increased 4-fold following implementation of the KAS with little change in allocation of kidneys with KDPI scores > 85%. Patient survival and graft loss were strongly associated with KDPI score, whereas the association with cPRA level was minimal. There was no evidence of a differential effect of KDPI scores across the range of cPRA levels on patient survival (P for interaction=0.06-0.9) or graft loss (P for interaction=0.5-0.9). Patient survival at 5 years among the 5 cPRA groups ranged from 87.2% to 89.8% for recipients of kidneys with KDPI scores ≤ 20% (P=0.2), 82.8% to 85.5% for KDPI scores of 21% to 85% (P=0.04), and 70.2% to 79.2% for KDPI scores > 85% (P=0.2). Cumulative incidence of graft loss by cPRA level ranged from 7.7% to 10.6% for recipients of kidneys with KDPI scores ≤ 20% (P=0.2), 11.8% to 15.0% for KDPI scores of 21% to 85% (P < 0.001), and 19.8% to 29.7% for KDPI scores > 85% (P = 0.4). LIMITATIONS: Lack of data for crossmatches, donor-specific antibodies, and immunomodulation. CONCLUSIONS: Highly sensitized recipients received kidneys with lower KDPI scores following implementation of the KAS, reducing access to these kidneys by less-sensitized candidates. KDPI score has a stronger association with patient survival and graft loss than cPRA level. The association of KDPI score with these outcomes was not modified by the recipient's level of sensitization. The impact of the redistribution of kidneys with low KDPI scores on outcomes among less-sensitized recipients needs further evaluation.

BACKGROUND: Transversus abdominis plane block may improve analgesia after colorectal surgery; however, techniques remain unstandardized and results are conflicting. OBJECTIVE: The purpose of this study was to compare laparoscopic and ultrasound-guided transversus abdominis plane block with no block in minimally invasive colorectal surgery. DESIGN: This was a randomized controlled trial. SETTINGS: The study was conducted at an urban teaching hospital. PATIENTS: Patients undergoing laparoscopic colorectal surgery were included. INTERVENTIONS: The intervention included 2:2:1 randomization to laparoscopic, ultrasound-guided, or no transversus abdominis plane block. MAIN OUTCOME MEASURES: Morphine use in the first 24 hours after surgery was measured. RESULTS: The study cohort included 107 patients randomly assigned to laparoscopic (n = 41), ultrasound-guided (n = 45), or no transversus abdominis plane block (n = 21). Mean age was 50.4 years (SD ± 18 y), and 50 patients (47%) were men. Laparoscopic transversus abdominis plane block was superior to ultrasound-guided (p = 0.007) and no transversus abdominis plane block (p = 0.007), with median (interquartile range) total morphine used in the first 24 hours postoperatively of 17.6 mg (6.6-33.9 mg), 34.0 mg (16.4-44.4 mg), and 31.6 mg (18.4-44.4 mg). At 48 hours, laparoscopic transversus abdominis plane block remained superior to ultrasound-guided (p = 0.03) and no transversus abdominis plane block (p = 0.007) with median (interquartile range) total morphine used at 48 hours postoperatively of 26.8 mg (15.5-45.8 mg), 44.0 mg (27.6-70.0 mg), and 60.8 mg (34.8-78.8 mg). Mean hospital stay was 5.1 ± 3.1 days without any intergroup differences. Overall complications were similar between groups. LIMITATIONS: Treatment teams were not blinded and there was operator dependence of techniques and variable timing of the blocks. CONCLUSIONS: Laparoscopic transversus abdominis plane block is superior to ultrasound-guided and no transversus abdominis plane block in achieving pain control and minimizing opioid use in the first 24 hours after colorectal surgery. A large, multicenter, randomized trial is needed to confirm our findings. See Video Abstract at http://links.lww.com/DCR/A822.

BACKGROUND: Resection of liver metastasis in small bowel neuroendocrine tumors (SBNET) may improve survival, however, factors influencing prognosis are unclear. We evaluated how the extent of resection influences outcomes. METHODS: Patients with SBNET with liver metastasis from 1990 to 2013 who underwent resection of the primary tumor were identified. Outcomes among patients undergoing complete resection (CR), partial resection (PR), or no resection (NR) of liver metastases with resection of the primary tumor only were compared. RESULTS: One hundred eleven patients met the criteria. The median number of liver lesions was seven and median lesions resected was one. Fifty (45%) patients had NR, 41 (36.9%) underwent CR, and 20 (18.1%) underwent PR. The 5-year overall survival (OS) was 79.4% for NR, 84.7% for PR, and 100% for CR, demonstrating a trend that CR was best, followed by PR then NR (P = .02). 10-year OS showed no significant differences (72.7% NR; 84.7% PR; 82.5% CR; P = .10). Greater than 10 liver lesions (hazard ratio [HR] 3.6; P = 0.04) or receiving chemotherapy (HR 3.7; P = .03) were negative predictors of survival. CONCLUSION: The extent of resection of liver disease in SBNET influenced survival at 5 years but not at 10 years. In addition, more than 10 liver lesions and chemotherapy were predictors of mortality.
