Presentation, patterns and predictive value of baseline liver tests on outcomes in COVID-19 patients without chronic liver disease.

BACKGROUND: Coronavirus disease 2019 (COVID-19) infection is known to cause abnormal hepatic enzymes. The long term consequences of such elevations are uncertain. AIM: To assessed the prevalence and prognostic value of initial liver enzymes in a large cohort of COVID-19 patients. METHODS: We reviewed electronic medical records of 10614 COVID-19 patients without known chronic liver disease who were admitted to our health system from March 1, 2020, to April 30, 2020. We analyzed baseline demographics and liver chemistries. The primary outcome was in-hospital mortality, and the secondary outcome was a composite of in-hospital mortality or need for mechanical ventilation. RESULTS: Subjects with abnormal liver tests had increased risks of mortality and composite outcome when compared to patients with normal measurements on unadjusted analysis and after adjustment for demographic factors. CONCLUSION: In our diverse patient population, liver enzyme abnormalities are associated with increased mortality and the need for mechanical ventilation in subjects without chronic liver disease. Cholestasis patients are at the greatest risk for poor outcomes.

Limiting hospital resources for acute appendicitis in children: Lessons learned from the U.S. epicenter of the COVID-19 pandemic.

INTRODUCTION: The COVID-19 pandemic resulted in the suspension of nonemergent surgeries throughout New York. Our tertiary care children's hospital pivoted towards a brief trial of intravenous (IV) antibiotic therapy in all patients in order to limit operating room (OR) utilization and avoid prolonged hospital stays. We describe our pandemic-based strategy for non-operative management (NOM) of appendicitis but with a limited duration of IV antibiotics. METHODS: We performed a retrospective study of children treated for acute appendicitis at our center from 3/31/2020 to 5/3/2020 during the peak of the New York pandemic. We compared appendicitis volume to similar months in prior years. We evaluated failure of NOM, length of stay, and compared characteristics of children we successfully treated with our expanded NOM protocol to previously published inclusion criteria for NOM. RESULTS: 45.5% of children (25/55) with acute appendicitis underwent NOM. Of the 30 who underwent surgery, 13 had complicated appendicitis while 17 had simple appendicitis. Three patients were COVID-positive, although none had respiratory symptoms. The majority of patients presenting with acute appendicitis (78.2%) did not meet previously published criteria for NOM. CONCLUSIONS: We treated a similar volume of children with acute appendicitis during the pandemic compared to prior years. We applied non-operative management to nearly half our patients, even as we expanded inclusion criteria for NOM to reduce OR utilization, but limited the duration of the antibiotic trial to avoid prolonged hospital stays. TYPE OF STUDY: Retrospective study. LEVEL OF EVIDENCE: IV.

Characteristics and risk factors associated with critical illness in pediatric COVID-19.

BACKGROUND: While much has been reported regarding the clinical course of COVID-19 in children, little is known regarding factors associated with organ dysfunction in pediatric COVID-19. We describe critical illness in pediatric patients with active COVID-19 and identify factors associated with PICU admission and organ dysfunction. This is a retrospective chart review of 77 pediatric patients age 1 day to 21 years admitted to two New York City pediatric hospitals within the Northwell Health system between February 1 and April 24, 2020 with PCR + SARS-CoV-2. Descriptive statistics were used to describe the hospital course and laboratory results and bivariate comparisons were performed on variables to determine differences. RESULTS: Forty-seven patients (61%) were admitted to the general pediatric floor and thirty (39%) to the PICU. The majority (97%, n = 75) survived to discharge, 1.3% (n = 1) remain admitted, and 1.3% (n = 1) died. Common indications for PICU admission included hypoxia (50%), hemodynamic instability (20%), diabetic ketoacidosis (6.7%), mediastinal mass (6.7%), apnea (6.7%), acute chest syndrome in sickle cell disease (6.7%), and cardiac dysfunction (6.7%). Of PICU patients, 46.7% experienced any significant organ dysfunction (pSOFA > = 2) during admission. Patients aged 12 years or greater were more likely to be admitted to a PICU compared to younger patients (p = 0.015). Presence of an underlying comorbidity was not associated with need for PICU admission (p = 0.227) or organ dysfunction (p = 0.87). Initial white blood cell count (WBC), platelet count, and ferritin were not associated with need for PICU admission. Initial C-reactive protein was associated with both need for PICU admission (p = 0.005) and presence of organ dysfunction (p = 0.001). Initial WBC and presenting thrombocytopenia were associated with organ dysfunction (p = 0.034 and p = 0.003, respectively). CONCLUSIONS: Age over 12 years and initial CRP were associated with need for PICU admission in COVID-19. Organ dysfunction was associated with elevated admission CRP, elevated WBC, and thrombocytopenia. These factors may be useful in determining risk for critical illness and organ dysfunction in pediatric COVID-19.

Outcomes of Initial Subtotal Colectomy for Pediatric Inflammatory Bowel Disease.

BACKGROUND: Subtotal colectomy with end ileostomy (STC-I) has been well established in the adult literature as an initial surgical treatment for refractory inflammatory bowel disease (IBD)-related colitis. However, in the pediatric population, the efficacy of this approach has been less well characterized, likely because of concerns regarding the advisability of leaving a diseased rectum in situ. Our aim was to examine the outcomes after STC-I for refractory IBD at our pediatric tertiary care center. METHODS: An institutional review board-approved retrospective review of patients aged 5-21 y who underwent operative treatment with initial STC-I for medically refractory IBD from January 2010 to August 2018. Only complications related to the STC-I were considered; complications subsequent to reconstruction are excluded from analysis. Early complications were defined as occurring within 60 d of STC-I. We performed descriptive statistics using the Fisher exact test and the Student t-test, as appropriate. RESULTS: Over the study period, 37 patients (aged 12.3 ± 4.2 y) underwent STC-I, with 73.0% performed laparoscopically. Patients were predominately male (51.4%) and Caucasian (48.6%). Thirty-one (83.8%) colectomies were performed for ulcerative colitis, two (5.4%) for Crohn disease, and four (10.8%) for indeterminate colitis. Nutritional status improved postcolectomy. Albumin levels of 3.3 ± 0.8 preoperatively increased to 4.3 ± 0.47 postoperatively (P < 0.001). Colonic bleeding was stopped by STC-I with increases in the hematocrit from 30.5 ± 6.8 preoperative to 38.9 ± 4.1 postoperatively (P < 0.001). Average time to discontinuation of IBD-related medications was 4 wk (n = 27). Forty-eight percent required outpatient rectal treatment for proctitis. Patients did well long term, with 67.5% reestablishing intestinal continuity at our institution. Average postoperative length of stay was shorter in the laparoscopic group compared with those undergoing open operations (5.1 ± 2.2 versus 6.9 ± 1.6 d, P = 0.03). Readmission rate at 30 d was 21.1%. Patients experiencing unplanned readmission or unplanned operations were similar between groups (30% versus 33.3%, P = 0.85 and 30% versus 18.5%, P = 0.45, respectively). Overall, 14 (37.8%) patients experienced a complication with many patients experiencing multiple complications. Early complications occurred in nine (24.3%) patients. Late complications also occurred in 24.3% of patients. There were four (10.8%) patients with five admissions for bowel obstruction, two of whom required operative intervention (5.4%). CONCLUSIONS: Use of STC-I as an initial procedure in the treatment of refractory IBD-related colitis in children is a safe and reasonable surgical approach that allows weaning from immunosuppressing mediations and stops colonic bleeding. Implementing a laparoscopic approach to subtotal colectomy provides further benefit by reducing postoperative length of stay.

Early Experience with Variant Two-Stage Approach in Surgical Management of Inflammatory Bowel Disease Colitis in the Pediatric Population.

Introduction: Multistaged surgical management of inflammatory bowel disease (IBD), culminating in ileal pouch-anal anastomosis (IPAA), can provide cure for refractory IBD symptoms while maintaining fecal continence. Surgical approaches to IPAA historically included a three-stage approach done by subtotal colectomy (STC) followed by IPAA with diversion. Recently, a variant two-stage approach without diversion at IPAA has become increasingly utilized, yet evidence of the efficacy of this approach is limited. Methods: Retrospective review of patients aged 5-21 years who underwent initial STC, followed by a total proctocolectomy with IPAA +/- diversion for medically refractory IBD from January 2010 to August 2018 (n = 25). Results: Majority of IPAA procedures were done laparoscopically (88.5%). Thirteen patients (52%) underwent two-stage variant IPAA. There were no differences in readmission rates (66.7% versus 53.8%, P = .5) or reoperation rates (50% versus 30.8%, P = .3) between groups. Forty percent of patients experienced a complication after IPAA. Complication rates were similar between two-stage and three-stage IPAA groups (38.5% versus 50%, P = .33). Complications within the two-stage group included anastomotic leak, pouchitis, wound infection, anastomotic stricture, and incarcerated hernia. Complications within the three-stage group included bloody ostomy output, dehydration, anastomotic stricture, small bowel obstruction, and pouch volvulus. Conclusions: Treatment of refractory IBD in children remains challenging, but STC followed by IPAA is an approach that provides symptom relief and preserves continence. Complication rates remained unchanged regardless of whether IPAA was conducted with or without diversion, demonstrating that the two-stage variant approach is a safe and feasible treatment that may reduce subsequent anesthesia exposure and trips to the operating room.

Modified open technique for laparoscopic gastrostomy tube placement results in more leakage post operatively than Seldinger technique.

BACKGROUND: Laparoscopic gastrostomy tube (GT) placement is a common procedure and frequent cause of morbidity. Some surgeons perform a Seldinger technique (ST), while others perform a modified open technique (MOT). We hypothesized that the modified open technique would result in more complications. METHODS: A prospective study of primary GT placed 12/2016-06/2018, ensuring at least 6 months follow up. We assessed any episode of granulation tissue, troublesome leaking, tube dislodgment, and infection requiring antibiotic or drainage. RESULTS: 92 GT were placed, with 56 were placed as modified open (60.9%). 34 children (37.0%) developed granulation tissue, 18 children (19.6%) experienced tube dislodgment, and 6 children (6.5%) developed a site infection, with no difference depending on technique (P = 0.56, 0.29, and 0.76, respectively). Following ST, 2 children developed leakage (5.6%), whereas 15 children (26.8%) had leakage following the MOT (P = 0.01). CONCLUSION: MOT resulted in significantly more leaks. Other complications were similar between groups. Surgeons choosing MOT should be mindful of the size of gastrotomy at time of surgery, as this may result in increased complications.

Emergency pediatric surgery: Comparing the economic burden in specialized versus nonspecialized children's centers.

BACKGROUND: The American College of Surgeons has developed a verification program for children's surgery centers. Highly specialized hospitals may be verified as Level I, while those with fewer dedicated resources as Level II or Level III, respectively. We hypothesized that more specialized children's centers would utilize more resources. STUDY DESIGN: We performed a retrospective study of the Maryland Health Services Cost Review Commission (HSCRC) database from 2009 to 2013. We assessed total charge, length of stay (LOS), and charge per day for all inpatients with an emergency pediatric surgery diagnosis, controlling for severity of illness (SOI). Using published resources, we assigned theoretical level designations to each hospital. RESULTS: Two hospitals would qualify as Level 1 hospitals, with 4593 total emergency pediatric surgery admissions (38.5%) over the five-year study period. Charges were significantly higher for children treated at Level I hospitals (all P<0.0001). Across all SOI, children at Level I hospitals had significantly longer LOS (all P<0.0001). CONCLUSION: Hospitals defined as Level II and Level III provided the majority of care and were able to do so with shorter hospitalizations and lower charges, regardless of SOI. As care shifts towards specialized centers, this charge differential may have significant impact on future health care costs. LEVEL OF EVIDENCE: Level III Cost Effectiveness Study.

Clinical and symptom scores are significantly correlated with fecal microbiota features in patients with symptomatic uncomplicated diverticular disease: a pilot study.

BACKGROUND: There is growing consensus that symptomatic uncomplicated diverticular disease is a chronic inflammatory condition, and that alterations in the fecal microbiota may contribute to its pathogenesis. OBJECTIVE: The aim of this study was to relate the fecal microbiota composition in symptomatic uncomplicated diverticular disease to measures of inflammation, symptoms, and history of previous acute diverticulitis. PARTICIPANTS AND METHODS: Fecal microbiota composition in 28 individuals with symptomatic uncomplicated diverticular disease was characterized by 16S RNA gene amplicon sequencing. Microbiota composition was related to clinical history, symptom and inflammation measures, and demographic variables. RESULTS: Previous acute diverticulitis was associated with higher relative abundance of Pseudobutyrivibrio, Bifidobacterium, Christensenellaceae family, and Mollicutes RF9 order (P=0.004, 0.006, 0.010, and 0.019, respectively), but not microbiota alpha or beta diversity. A higher bloating severity score was significantly correlated with a higher relative abundance of Ruminococcus (P=0.032), and significantly inversely correlated with the relative abundance of the Roseburia (P=0.002). Fecal calprotectin levels were positively correlated with alpha diversity (Shannon index, P=0.005) and the relative abundance of Lactobacillus (P=0.004). Pain score was positively correlated with the relative abundance of Cyanobacterium (adjusted P=0.032). CONCLUSION: Patient symptoms in symptomatic diverticular disease are significantly correlated with features of the fecal microbiota. Our findings suggest the potential utility of therapies that target intestinal microbiology, such as dietary prebiotic supplements.

A randomized double-blind placebo-controlled trial of a multi-strain probiotic in treatment of symptomatic uncomplicated diverticular disease.

BACKGROUND: Diverticular disease is a significant burden on healthcare systems that is managed, surgically or medically, mainly as an emergency or acute condition. There are no standardized treatment recommendations for symptomatic uncomplicated disease. We hypothesized that a probiotic would reduce abdominal pain in such patients. METHODS: We conducted a single-center, double-blind, placebo-controlled trial of probiotic treatment (Symprove) in adult patients with moderate-to-severe chronic, non-acute symptomatic diverticular disease. 143 patients were randomized to receive 1 mL/kg/day of probiotic liquid (N = 72) or placebo (N = 71) daily for 3 months. The primary endpoint was abdominal pain severity. Secondary endpoints consisted of the change in the frequency of eight abdominal symptoms and the level of intestinal inflammation (fecal calprotectin). RESULTS: 120 patients completed the trial. Abdominal pain score, the primary end point, decreased in both groups, but no significant difference between the groups was found (P = 0.11). In relation to placebo, the probiotic significantly decreased the frequency of four of the eight secondary endpoints: constipation, diarrhea, mucorrhea, and back pain (P < 0.04). No significant differences were found in frequency of abdominal pain, PR bleeding, dysuria, and bloating. CONCLUSIONS: Multi-strain liquid probiotic did not improve abdominal pain scores significantly, but significantly improved the frequency of four other symptoms associated with chronic, non-acute symptomatic diverticular disease.

Treatment Outcomes for Patients with Extensively Drug-Resistant Tuberculosis, KwaZulu-Natal and Eastern Cape Provinces, South Africa.

We analyzed data for a retrospective cohort of patients treated for extensively drug-resistant tuberculosis in 2 provinces in South Africa and compared predictors of treatment outcome in HIV-positive patients who received or had not received antiretroviral drugs with those for HIV-negative patients. Overall, 220 (62.0%) of 355 patients were HIV positive. After 2 years, 34 (10.3%) of 330 patients with a known HIV status and known outcome had a favorable outcome. Multivariate analysis showed that predictors of favorable outcome were negative results for acid-fast bacilli by sputum microscopy at start of treatment and weight >50 kg. HIV-positive patients were more likely to have an unfavorable outcome. The strongest predictor of unfavorable outcome was weight <50 kg. Overall outcomes were poor. HIV status was not a predictor of favorable outcome, but HIV-positive patients were more likely to have an unfavorable outcome. These results underscore the need for timely and adequate treatment for tuberculosis and HIV infection.

Diverticular disease as a chronic gastrointestinal condition: experience from a specialist clinic.

BACKGROUND: Although diverticular disease is a prevalent condition and a significant burden on the healthcare system, care is devolved across gastrointestinal, GP, and colorectal surgery clinics. We created a specialist Diverticular Disease Clinic to streamline care, enhance evidence-based practice and provide a base for research. The aim of this study was to assess patient referral sources, predictors of persistent disease and surgical outcomes. METHODS: We retrospectively reviewed all patients attending our clinic. Patients younger than 50 years of age on initial presentation were considered 'younger' patients. Persistent symptoms lasted for at least 3 months. RESULTS: Overall, 177 patients had confirmed diverticular disease. Patients were referred following hospital admission (82 patients, 46.3%) or from the community (95 patients, 53.7%). Ninety-five patients (53.7%) had persistent symptoms. Patients with more than two episodes of diverticulitis were more likely to have persistent symptoms (P<0.0001).Following hospitalization, younger patients were 3.98 times more likely to develop persistent symptoms (P=0.04). This was independent of the severity of the original infection, as a low peak C-reactive protein level of less than 50 mg/L was associated with persistent symptoms (odds ratio=3.62, P=0.03). Over the study period, 12 patients (6.9%) had elective surgery. CONCLUSION: There is demand for dedicated care for patients with persistent symptoms from diverticular disease. Specialized clinics are a model for this care, provided by either gastroenterologists or surgeons, in centres with adequate demand. Our findings reinforce the hypotheses that chronic abdominal pain in diverticular disease may be related to sensation abnormalities similar to postinfective irritable bowel syndrome.

Utilization of High-frequency Mini Probe Ultrasound in the Assessment of Colonic Wall Thickness in Patients With Diverticular Disease: A Feasibility Study.

BACKGROUND: Assessment of diverticular disease (DD) is routinely undertaken by colonoscopy and computed tomography (CT) scan. Improvements in high-frequency ultrasound have enabled evaluation of the colon wall structure in detail. Our objective was to assess ultrasound in measuring colonic wall thickness in DD. METHODS: High-frequency 20-MHz ultrasound was undertaken to measure individual layer and total colonic wall thickness. Case patients had symptomatic DD. Control patients underwent colonoscopy for other reasons. Select patients also underwent abdominal CT scan. RESULTS: Thirty-three patients underwent colonoscopic ultrasound, 18 with sigmoid diverticula and 15 control patients.Total wall thickness was greater in patients with DD, 5.69 mm (1.68) versus 2.61 mm (1.29, P<0.0001). Patients with DD had significant thickening in each individual layer of the colonic wall measured (each P<0.0001).Greatest differences were in the muscularis propria, which was an average of 3.5 times thicker in patients with DD. In patients with DD, the segment of colonic wall measured was also thicker, with average mid-sigmoid thickness of 23.0 mm (SD 9.6 mm). CONCLUSIONS: Patients with DD have increased sigmoid thickness when compared with controls, especially the muscularis propria. Unlike CT, ultrasound was also able to identify thickening in the mucosa and submucosa.

Nonsteroidal anti-inflammatory drugs and exacerbations of inflammatory bowel disease.

BACKGROUND: Nonsteroidal anti-inflammatory drugs (NSAIDs) are the most commonly prescribed analgesics for treatment of variety of pain and inflammatory conditions. Their effects on the gastrointestinal tract are well described, but their possible propensity to cause clinical relapse in patients with inflammatory bowel disease (IBD) remains somewhat unclear. AIM: We reviewed case reports, case-control and cohort studies, as well as clinical trials of NSAIDs in patients with quiescent IBD in order to better assess the magnitude and type of effect. RESULTS: The published literature on this subject is of mixed quality and many of the studies are open to criticism. The majority of patients with IBD tolerate these medications, while in the sole clinical trial of NSAIDs 20% experienced a clinical and laboratory documented relapse of disease, within 7-10 days of NSAID ingestion. The data on cyclooxygenase (COX)-2-selective anti-inflammatory analgesic are somewhat unclear, but nimesulide, celecoxib and etoricoxib do not appear to be associated with relapse of disease. CONCLUSION: Conventional NSAIDs may cause clinical relapse in about 20% of patients with quiescent IBD, which may be due to dual inhibition of the COX enzymes. Certain COX-2-selective NSAIDs appear to be safe.

Expansion of screening mammography in the Veterans Health Administration: implications for breast cancer treatment.

IMPORTANCE: Women represent the fastest-growing demographic in the Veterans Health Administration. In 2008, we implemented programmatic changes to expand screening mammography, develop on-site breast care resources, and better coordinate care with non-Veterans Affairs (VA) facilities. OBJECTIVE: To determine whether the programmatic changes would increase patient volumes, decrease time to definitive treatment, and increase the rate of breast conservation therapy (BCT). DESIGN, SETTING, AND PARTICIPANTS: We performed a retrospective cohort study of all breast cancer cases treated from January 1, 2000, to May 31, 2012, at the Baltimore VA Medical Center. MAIN OUTCOMES AND MEASURES: We compared process-of-care metrics before and after 2008, when programmatic changes were implemented. Metrics evaluated included the number of mammograms performed annually, sex shift, the interval from clinical suspicion to tissue diagnosis and definitive treatment, and the rate of BCT. RESULTS: From 2000 to 2012, a total of 7355 mammograms were performed and 76 patients with breast cancer received treatment. Most mammograms (n = 6720) were performed after 2008. A median of 1453 (interquartile range [IQR], 592-1458) mammograms were performed and 6.33 patients received cancer treatment annually after 2008, representing 1200% and 49% increases, respectively, compared with the 2000 to 2007 interval. Most patients (86.7%) received screening and diagnostic imaging, biopsy, and surgery between multiple institutions. The interval between screening mammography and tissue diagnosis was 34 days (IQR, 20-52), with no significant difference between study intervals (P = .18). Time from tissue diagnosis to initiation of definitive treatment increased from 33 days (IQR, 26-51) to 51 days (IQR, 36-75) (P = .03) between 2008 and 2012. Thirty-three patients eligible for BCT (67.3%) received it, while 16 patients (32.7%) underwent mastectomy. CONCLUSIONS AND RELEVANCE: Our institution has rapidly and successfully expanded screening mammography. Higher mammography volumes have been associated with increased use of non-VA breast care services and increased time to definitive treatment. Appropriate counseling regarding BCT was consistently documented, and mastectomy in BCT-eligible patients was largely the result of patient preference or clinical/social factors. Our data suggest that as patient volumes increase with intensified screening, VA hospitals may benefit from acquiring a full complement of on-site breast care services rather than improving flow between VA hospitals and non-VA breast care centers having specialized resources.

Extensively drug-resistant TB in Eastern Cape, South Africa: high mortality in HIV-negative and HIV-positive patients.

BACKGROUND: Tuberculosis is a leading cause of morbidity and mortality worldwide. Patients with extensively drug-resistant tuberculosis (XDR-TB) have had high mortality rates, especially when coinfected with HIV. METHODS: A retrospective cohort study of the first 206 patients treated for XDR-TB in Eastern Cape Province, South Africa, October 2006 to January 2008, a province that has treated multidrug-resistant tuberculosis since 2000. All 206 patients were hospitalized for treatment until monthly sputum specimens were culture negative. RESULTS: Sixty-five patients diagnosed with XDR-TB died before XDR-TB treatment start. Among 195 patients starting treatment with a known HIV status, 108 (55.4%) were HIV positive, and 86 patients (44.1%) died during the first year of treatment. HIV-positive patients receiving antiretroviral treatment (ARVs) fared and HIV-negative patients, and more of both these groups survived than HIV-positive patients not on ARVs. However, HIV-negative patients experienced more serious adverse events requiring the withdrawal of medications than did HIV-positive patients, regardless of the use of ARVs. CONCLUSIONS: Experience in Eastern Cape Province, South Africa, suggests that patients can be treated for both XDR-TB and HIV. We have also shown that such combination therapy can be well tolerated by patients.
