Abstract
INTRODUCTION The efficacy of antibiotics for diverticulitis without abscess or peritonitis (uncomplicated diverticulitis) is controversial. We aimed to investigate the effectiveness of antibiotics for uncomplicated diverticulitis. METHODS We collected admission data for patients with acute uncomplicated diverticulitis using a nationwide database. We divided eligible admissions into two groups according to antibiotic initiation within 2 days after admission (antibiotic group vs. nonantibiotic group). We conducted propensity score matching and compared the rates of surgery (intestinal resection and stoma creation), in-hospital death, and medical costs between the groups. We also performed multivariate analysis to identify the clinical factors that affect surgery. RESULTS We enrolled 131,936 admissions; among these, we obtained 6,061 pairs after propensity score matching. Rates of both intestinal resection and stoma creation in the antibiotic group were lower than those in the nonantibiotic group (0.61 vs. 3.09%, p < 0.0001, and 0.08 vs. 0.26%, p = 0.027, respectively). Median costs in the antibiotic group were higher than those in the nonantibiotic group (315,820 JPY vs. 300,175 JPY, p < 0.0001, respectively). Multivariate analysis showed that non-initiation of antibiotics within 2 days after admission was a clinical factor that increased the risk of intestinal resection (odds ratio [OR] = 5.19, 95% confidence interval [CI]: 4.38-6.16, p < 0.0001) and stoma creation (OR = 2.68, 95% CI: 1.53-4.70, p = 0.0006). CONCLUSION Our results indicated that antibiotics for uncomplicated diverticulitis expected to have moderate to severe disease activity may reduce the risk of intestinal resection and stoma creation. Further investigations are warranted.

Abstract
BACKGROUND After initial nonoperative management of diverticulitis, individuals with a family history of diverticulitis may have increased risk of recurrent disease. OBJECTIVE This study measured the association between family history and recurrent diverticulitis in a population-based cohort. DESIGN This is a retrospective, population-based cohort study. SETTINGS The cohort was identified from the Utah Population Database, a statewide resource linking hospital and genealogy records. PATIENTS Individuals evaluated in an emergency department or hospitalized between 1998 and 2018 for nonoperatively managed diverticulitis were included. INTERVENTION The primary predictor was a positive family history of diverticulitis, defined as diverticulitis in a first-, second-, or third-degree relative. MAIN OUTCOME MEASURES This study measured the adjusted association between family history and the primary outcome of recurrent diverticulitis. A secondary outcome was elective surgery for diverticulitis. Additional analyses evaluated risk by degree of relation of the affected family member. RESULTS The cohort included 4426 individuals followed for a median of 71 months. Median age was 64 years and 45% were male; 17% had complicated disease, 11% had recurrence, and 15% underwent elective surgery. After adjustment, individuals with a family history of diverticulitis had a similar risk of recurrence when compared to those without a family history (HR 1.0; 95% CI 0.8-1.2). However, individuals with a family history of diverticulitis were more likely to undergo elective surgery (HR 1.4; 95% CI 1.1-1.6). This effect was most pronounced in those with an affected first-degree family member (HR 1.7; 95% CI 1.4-2.2). LIMITATIONS The use of state-specific data may limit generalizability. CONCLUSIONS In this population-based analysis, individuals with a family history of diverticulitis were more likely to undergo elective surgery than those without a family history, despite similar risks of recurrence and complicated diverticulitis. Further work is necessary to understand the complex social, environmental, and genetic factors that influence diverticulitis treatment and outcomes.

Después del ajuste, los individuos con antecedentes familiares de diverticulitis tenían un riesgo similar de recurrencia en comparación con aquellos sin antecedentes familiares (HR 1,0; IC del 95%: 0,8-1,2). Sin embargo, las personas con antecedentes familiares de diverticulitis tenían más probabilidades de someterse a una cirugía electiva (HR 1,4; IC del 95%: 1,1-1,6). Este efecto fue más pronunciado en aquellos con un familiar de primer grado afectado (HR 1,7; IC del 95%: 1,4-2,2).LIMITACIONES:El uso de datos específicos del estado puede limitar la generalización.CONCLUSIONES:En este análisis poblacional, los individuos con antecedentes familiares de diverticulitis tenían más probabilidades de someterse a una cirugía electiva que aquellos sin antecedentes familiares, a pesar de riesgos similares de recurrencia y diverticulitis complicada. Es necesario seguir trabajando para comprender los complejos factores sociales, ambientales y genéticos que influyen en el tratamiento y los resultados de la diverticulitis.

Abstract
BACKGROUND Outpatient diverticulitis is commonly treated with either a combination of metronidazole and a fluoroquinolone (metronidazole-with-fluoroquinolone) or amoxicillin-clavulanate alone. The U.S. Food and Drug Administration advised that fluoroquinolones be reserved for conditions with no alternative treatment options. The comparative effectiveness of metronidazole-with-fluoroquinolone versus amoxicillin-clavulanate for diverticulitis is uncertain. OBJECTIVE To determine the effectiveness and harms of metronidazole-with-fluoroquinolone versus amoxicillin-clavulanate for outpatient diverticulitis. DESIGN Active-comparator, new-user, retrospective cohort studies. SETTING Nationwide population-based claims data on U.S. residents aged 18 to 64 years with private employer-sponsored insurance (2000 to 2018) or those aged 65 years or older with Medicare (2006 to 2015). PARTICIPANTS Immunocompetent adults with diverticulitis in the outpatient setting. INTERVENTION Metronidazole-with-fluoroquinolone or amoxicillin-clavulanate. MEASUREMENTS 1-year risks for inpatient admission, urgent surgery, and Clostridioides difficile infection (CDI) and 3-year risk for elective surgery. RESULTS In MarketScan (IBM Watson Health), new users of metronidazole-with-fluoroquinolone (n = 106 361) and amoxicillin-clavulanate (n = 13 160) were identified. There were no differences in 1-year admission risk (risk difference, 0.1 percentage points [95% CI, -0.3 to 0.6]), 1-year urgent surgery risk (risk difference, 0.0 percentage points [CI, -0.1 to 0.1]), 3-year elective surgery risk (risk difference, 0.2 percentage points [CI, -0.3 to 0.7]), or 1-year CDI risk (risk difference, 0.0 percentage points [CI, -0.1 to 0.1]) between groups. In Medicare, new users of metronidazole-with-fluoroquinolone (n = 17 639) and amoxicillin-clavulanate (n = 2709) were identified. There were no differences in 1-year admission risk (risk difference, 0.1 percentage points [CI, -0.7 to 0.9]), 1-year urgent surgery risk (risk difference, -0.2 percentage points [CI, -0.6 to 0.1]), or 3-year elective surgery risk (risk difference, -0.3 percentage points [CI, -1.1 to 0.4]) between groups. The 1-year CDI risk was higher for metronidazole-with-fluoroquinolone than for amoxicillin-clavulanate (risk difference, 0.6 percentage points [CI, 0.2 to 1.0]). LIMITATION Residual confounding is possible, and not all harms associated with these antibiotics, most notably drug-induced liver injury, could be assessed. CONCLUSION Treating diverticulitis in the outpatient setting with amoxicillin-clavulanate may reduce the risk for fluoroquinolone-related harms without adversely affecting diverticulitis-specific outcomes.

Abstract
Machine learning applications in cardiology have rapidly evolved in the past decade. With the availability of machine learning tools coupled with vast data sources, the management of atrial fibrillation (AF), a common chronic disease with significant associated morbidity and socioeconomic impact, is undergoing a knowledge and practice transformation in the increasingly complex healthcare environment. Among other advances, deep-learning machine learning methods, including convolutional neural networks, have enabled the development of AF screening pathways using the ubiquitous 12-lead ECG to detect asymptomatic paroxysmal AF in at-risk populations (such as those with cryptogenic stroke), the refinement of AF and stroke prediction schemes through comprehensive digital phenotyping using structured and unstructured data abstraction from the electronic health record or wearable monitoring technologies, and the optimization of treatment strategies, ranging from stroke prophylaxis to monitoring of antiarrhythmic drug (AAD) therapy. Although the clinical and population-wide impact of these tools continues to be elucidated, such transformative progress does not come without challenges, such as the concerns about adopting black box technologies, assessing input data quality for training such models, and the risk of perpetuating rather than alleviating health disparities. This review critically appraises the advances of machine learning related to the care of AF thus far, their potential future directions, and its potential limitations and challenges.

Abstract
OBJECTIVE Abuse and misuse of prescription opioids is a significant public health concern. This review examines the strategies used to confer abuse-deterrent properties on opioid abuse-deterrent formulations (ADFs), the characteristics and supporting data for each of the available ADFs, and the role of opioid ADFs as part of a comprehensive opioid risk management plan. METHODS A PubMed search was performed for articles published within the last 10 years using the search terms "abuse deterrent opioids". Articles were limited to clinical studies and reviews focusing on United States (US) Food and Drug Administration (FDA)-approved opioid ADFs in the US. RESULTS There are currently nine extended-release and one immediate-release opioid pain medications with US FDA-approved ADF labelling. All use either physical and chemical barriers or agonist/antagonist combinations to deter manipulation and abuse. Evidence is mounting that introduction of opioid ADFs has been associated with decreased rates of abuse and diversion of opioids in the US. CONCLUSIONS Although not sufficient by themselves to prevent prescription opioid abuse and misuse, opioid ADFs are an important component of a healthcare provider's comprehensive opioid risk management plan (along with utilization of prescription drug monitoring programs, clinical assessment tools, urine tests, co-prescribing of naloxone to patients at risk of an overdose, access to non-pharmacological treatments and addiction/mental health resources, among others). Adoption of opioid ADFs should be considered as part of an overall public health opioid risk management plan involving all stakeholders to balance legitimate safe and effective use of opioids against misuse and abuse.

Abstract
BACKGROUND Diverticulitis is a common and morbid disease with incompletely understood risk factors and pathophysiology. Geographic and, recently, seasonal trends in diverticulitis have been described in the United States. OBJECTIVE The purpose of this study was to investigate and compare seasonal trends in urgent hospital admission for diverticulitis in geographically distinct populations in the northern and southern hemispheres. DESIGN Inpatient, urgent admissions for diverticulitis were identified within the Dr Foster Intelligence Global Comparators Dataset, a global benchmarking collaborative. SETTINGS Admissions to participating hospitals in the United Kingdom, Australia, and the United States were identified between 2008 and 2013. PATIENTS A total of 18,672 urgent admissions for diverticulitis were identified among 5.5-million admissions. MAIN OUTCOME MEASURES Four separate hypothesis testing methods were used to identify seasonal trends in diverticulitis admissions among international patient populations. RESULTS Seasonal trends were present in all 3 countries. A summer peak was observed in both hemispheres using multiple statistical testing methods. Logistic regression analyses identified summer months as significantly associated with diverticulitis admission in all 3 countries. LIMITATIONS This study is limited by restriction to inpatient admissions, reliance on administrative data, and participation of select hospitals within the database. CONCLUSIONS These data suggest a shared seasonal risk factor among geographically distinct populations for diverticulitis.

Abstract
BACKGROUND Physicians often diagnose diverticulitis and prescribe antibiotics in outpatients with abdominal pain and tenderness without other evidence. AIM We investigated the misattribution of irritable bowel syndrome (IBS) symptoms to diverticulitis in outpatients. METHODS In patients diagnosed with diverticulitis and dispensed antibiotics in an integrated healthcare system, we retrospectively compared 15,846 outpatients managed without computed tomography (CT) versus 3750 emergency department/inpatients who had CT. We assessed demographics and past history, including 17 symptom-based somatic and 11 mental disorders and three somatic-mental comorbidity pairs (dyads) coded over 3 years and seven drug classes dispensed over 1 year before diagnosis. RESULTS Univariate analysis showed small intergroup demographic differences. Outpatients had increases in prior diverticulitis, including outpatient-managed episodes, total somatic diagnoses (p < .0001), eight somatic and three mental disorders (p ≤ .015), all three dyads (p ≤ .05), and dispensing of three drug classes (p ≤ .016). IBS had been diagnosed in 2399 (15.1 %) outpatients versus 361 (9.6 %) emergency department/inpatients (p < .0001), the greatest increase in any comorbidity. Emergency department/inpatients had no somatic comorbidity more often but more alcohol dependence, non-dependent drug abuse, and opioid dispensing (p ≤ .05). Regression analysis revealed outpatient care was independently positively associated with younger age, non-Hispanic white race/ethnicity, less Charlson comorbidity, diverticulitis history, IBS, chest pain, dyspepsia, fibromyalgia, low back pain, migraine, acute reaction to stress, and antispasmodic and anxiolytic dispensing and negatively associated with non-dependent drug abuse and opioid dispensing (p ≤ .0226). CONCLUSIONS Multiple types of indirect and concordant evidence suggest misattribution of IBS pain to diverticulitis and unnecessary antibiotic therapy in outpatients.
