Increased Risk of Herpes Zoster Infection in Patients with Celiac Disease 50 Years Old and Older.

BACKGROUND: Celiac Disease (CD) is associated with increased susceptibility to certain bacterial and viral infections. Herpes zoster (HZ) is a viral infection that can be prevented by immunization. In the US, the vaccine is recommended for adults ≥ 50 or ≥ 19 with certain at-risk conditions, not including CD. AIMS: We aimed to determine if adult patients aged < 50 or ≥ 50 years with CD had a higher risk of developing HZ. METHODS: We designed a retrospective cohort study. CD was defined as patients with the ICD-10 code for CD and positive Celiac serology. Patients with negative serology and lacking CD ICD-10 codes served as controls. Patients who had HZ before CD diagnosis were excluded. We formed two sub-cohorts, those aged < 50 (cohort 1) and aged ≥ 50 years (cohort 2), and evaluated HZ infection at 10-year follow-up. To account for confounding variables, we performed 1:1 propensity score matching (PSM). RESULTS: Following PSM, cohort 1 had 6,826 CD patients, and cohort 2 had 5,337 CD patients and respective matched controls. After ten years of follow-up, in cohort 1, 62 CD patients developed HZ versus 57 controls, RR: 1.09 (CI: 0.76-1.56, p-value = 0.64). In cohort 2, 200 CD patients developed HZ versus 159 controls, RR: 1.2 (CI: 1.02-1.54, p-value = 0.03). CONCLUSION: There was no significant difference in the likelihood of getting HZ in CD patients < 50, although CD patients ≥ 50 had a modestly increased risk. Our findings do not support routine early vaccination for HZ in CD, and the vaccine should be offered at age 50.

Increased Risk of Hospitalization in Celiac Disease With COVID-19 Infection Is Mitigated by Vaccination.

BACKGROUND: We sought to describe clinical characteristics of celiac disease (CD) patients infected with coronavirus disease 2019 (COVID-19) and estimate hospitalization risk, intensive care unit (ICU) requirement, mortality, and thrombosis, and the impact of vaccination on these outcomes. METHODS: We performed a single-center, retrospective cohort study comparing biopsy-proven CD patients with a matched sample of non-CD (referent) patients diagnosed with COVID-19 between March 2020 and January 2022. Matching ensured 2 referent patients for every 1 CD patient by age, sex, ethnicity, and COVID-19 diagnosis date. We also adjusted for general and celiac-specific comorbidity. The primary outcome was hospitalization. Secondary outcomes included ICU requirement, mortality, and thrombosis. We also compared these outcomes between vaccinated and unvaccinated individuals. RESULTS: We included 330 patients: 110 with CD (mean age 47 years, 83% female) and 220 matched referents. Hospitalization occurred in 27 CD patients (24%) and 25 referent patients (11%) (hazard ratio, 2.10; 95% confidence interval, 1.21-3.65; P = .009). Vaccination was associated with significantly decreased risk of hospitalization (hazard ratio, 0.53; 95% confidence interval, 0.31-0.93; P = .026). Four unvaccinated CD patients and 2 unvaccinated referent patients required ICU. No mortality occurred among CD patients, and 2 referent patients died. No thrombosis occurred in either group. CONCLUSIONS: CD patients with COVID-19 have a higher risk of hospitalization compared with non-CD referents. This risk is mitigated by vaccination in CD patients as it is in non-CD referents. ICU requirement occurred only in unvaccinated CD patients, and no CD patient died. Vaccination against COVID-19 should be strongly recommended in patients with CD as it is for non-CD patients in the general population.

Sedation for Bronchoscopy and Complications in Obese Patients.

BACKGROUND: Bronchoscopy is a safe and minimally invasive diagnostic tool, but no studies have reported prospectively on sedation and outcomes in patients with objectively defined obesity. OBJECTIVES: The purpose of the study is to determine if obese patients require more sedation or had more procedural complications during bronchoscopy under moderate sedation than non-obese patients. METHODS: We evaluated complications and sedation requirements in non-obese versus obese patients, defined by multiple criteria including body mass index (BMI), neck circumference, abdominal height, and Mallampati scores. RESULTS: Data were collected prospectively in 258 patients undergoing bronchoscopy under moderate sedation. By varying criteria, there were the following proportions of obese patients: 30% by BMI >30, 39% by neck circumference >40 cm, and 35% by abdominal height >22 cm in males and >20 cm in females. Sedative and analgesic dosing was not clinically significantly higher in obese patients than in non-obese patients. There was no difference in complications or procedural success based on obesity criteria. Hemoglobin oxygen desaturations occurred more often during bronchoscopy in patients with increasing Mallampati scores (p = 0.04), but this had no effect on bronchoscopy time or successful completion of the procedure. A subset of patients with previous polysomnogram-proven obstructive sleep apnea were more likely to have earlier termination of their procedure (15.8%) than patients with no diagnosed sleep apnea (2.3%; p = 0.002). CONCLUSION: In this prospective assessment of patients with obesity, we found neither clinically significant differences in sedation needs nor increases in complications in obese versus non-obese patients using a variety of indices of obesity.

Standardized Rehabilitation and Hospital Length of Stay Among Patients With Acute Respiratory Failure: A Randomized Clinical Trial.

IMPORTANCE: Physical rehabilitation in the intensive care unit (ICU) may improve the outcomes of patients with acute respiratory failure. OBJECTIVE: To compare standardized rehabilitation therapy (SRT) to usual ICU care in acute respiratory failure. DESIGN, SETTING, AND PARTICIPANTS: Single-center, randomized clinical trial at Wake Forest Baptist Medical Center, North Carolina. Adult patients (mean age, 58 years; women, 55%) admitted to the ICU with acute respiratory failure requiring mechanical ventilation were randomized to SRT (n=150) or usual care (n=150) from October 2009 through May 2014 with 6-month follow-up. INTERVENTIONS: Patients in the SRT group received daily therapy until hospital discharge, consisting of passive range of motion, physical therapy, and progressive resistance exercise. The usual care group received weekday physical therapy when ordered by the clinical team. For the SRT group, the median (interquartile range [IQR]) days of delivery of therapy were 8.0 (5.0-14.0) for passive range of motion, 5.0 (3.0-8.0) for physical therapy, and 3.0 (1.0-5.0) for progressive resistance exercise. The median days of delivery of physical therapy for the usual care group was 1.0 (IQR, 0.0-8.0). MAIN OUTCOMES AND MEASURES: Both groups underwent assessor-blinded testing at ICU and hospital discharge and at 2, 4, and 6 months. The primary outcome was hospital length of stay (LOS). Secondary outcomes were ventilator days, ICU days, Short Physical Performance Battery (SPPB) score, 36-item Short-Form Health Surveys (SF-36) for physical and mental health and physical function scale score, Functional Performance Inventory (FPI) score, Mini-Mental State Examination (MMSE) score, and handgrip and handheld dynamometer strength. RESULTS: Among 300 randomized patients, the median hospital LOS was 10 days (IQR, 6 to 17) for the SRT group and 10 days (IQR, 7 to 16) for the usual care group (median difference, 0 [95% CI, -1.5 to 3], P = .41). There was no difference in duration of ventilation or ICU care. There was no effect at 6 months for handgrip (difference, 2.0 kg [95% CI, -1.3 to 5.4], P = .23) and handheld dynamometer strength (difference, 0.4 lb [95% CI, -2.9 to 3.7], P = .82), SF-36 physical health score (difference, 3.4 [95% CI, -0.02 to 7.0], P = .05), SF-36 mental health score (difference, 2.4 [95% CI, -1.2 to 6.0], P = .19), or MMSE score (difference, 0.6 [95% CI, -0.2 to 1.4], P = .17). There were higher scores at 6 months in the SRT group for the SPPB score (difference, 1.1 [95% CI, 0.04 to 2.1, P = .04), SF-36 physical function scale score (difference, 12.2 [95% CI, 3.8 to 20.7], P = .001), and the FPI score (difference, 0.2 [95% CI, 0.04 to 0.4], P = .02). CONCLUSIONS AND RELEVANCE: Among patients hospitalized with acute respiratory failure, SRT compared with usual care did not decrease hospital LOS. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT00976833.

Age at asthma onset and asthma self-management education among adults in the United States.

OBJECTIVE: Asthma self-management education improves asthma-related outcomes. We conducted this analysis to evaluate variation in the percentages of adults with active asthma reporting components of asthma self-management education by age at asthma onset. METHODS: Data from 2011 to 2012 Asthma Call-back Surveys were used to estimate percentages of adults with active asthma reporting six components of asthma self-management education. Components of asthma self-management education include having been taught to what to do during an asthma attack and receiving an asthma action plan. Differences in the percentages of adults reporting each component and the average number of components reported across categories of age at asthma onset were estimated using linear regression, adjusted for age, education, race/ethnicity, sex, smoking status, and years since asthma onset. RESULTS: Overall, an estimated 76.4% of adults with active asthma were taught what to do during an asthma attack and 28.7% reported receiving an asthma action plan. Percentages reporting each asthma self-management education component declined with increasing age at asthma onset. Compared with the referent group of adults whose asthma onset occurred at 5-14 years of age, the percentage of adults reporting being taught what to do during an asthma attack was 10% lower among those whose asthma onset occurred at 65-93 years of age (95% CI: -18.0, -2.5) and the average number of components reported decreased monotonically across categories of age at asthma onset of 35 years and older. CONCLUSIONS: Among adults with active asthma, reports of asthma self-management education decline with increasing age at asthma onset.

Reliability in reporting asthma history and age at asthma onset.

BACKGROUND: Evaluation of the prevalence and incidence of asthma and research into its etiology often rely on self-reported information. We conducted this analysis to investigate reliability in reporting asthma history across categories of demographic and socio-economic characteristics. METHODS: We analyzed data from 3109 participants in the Coronary Artery Risk Development in Young Adults study, a longitudinal study of African-American and white adults. Responses to self-administered questionnaires completed at 15- and 20-year follow-up exams were used to evaluate agreement in reporting asthma history and age at diagnosis and assess variation in agreement across categories of demographic and health-related characteristics. RESULTS: A history of asthma was reported by 12% of participants at the 15-year exam and 11% of participants at the 20-year exam, with 97% agreement and an overall Kappa coefficient of 0.845 (95% confidence interval: 0.815-0.874). Kappa coefficients were higher among women than men and increased monotonically across categories of educational attainment. One-hundred eight participants (35%) reported exactly the same age at diagnosis at the two time points; for another 120 (39%), the difference in reported ages was ≤2 years. Age at asthma diagnosis reported at the 20-year exam was, on an average, 1 year (SD: 5.2) older than that reported at the 15-year exam. CONCLUSIONS: Five-year reliability in self-reported asthma history is high, and variation in reporting age at diagnosis is low across categories of participant characteristics. Nevertheless, agreement in responses at two times does not guarantee that self-administered questionnaires are sensitive tools for detecting a true asthma history.

Training in and experience with endobronchial ultrasound.

BACKGROUND: Diagnosing mediastinal and hilar lymphadenopathy and staging lung cancer with endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration (TBNA) are on the rise, but uncertainty surrounds the optimal number of cases needed to achieve acceptable yields. OBJECTIVES: To determine the threshold at which EBUS-TBNA reaches adequate yields among trainees and skilled bronchoscopists. METHODS: We reviewed all EBUS-TBNAs performed at our medical center since implementing the use of EBUS (n = 222). RESULTS: EBUS-TBNAs were performed in 222 patients (344 nodes). The percentage of adequate specimens sampled (diagnostic specimens or nodal tissue) rose from 66% in 2008 to 90% in 2012 (p < 0.01) and cancer yield improved from 34% in 2008 to 48% in 2012 (p < 0.01). Attending physicians who performed an average of more than 10 procedures per year had higher yields compared to those who performed fewer than 10 procedures per year (86 vs. 68%, p < 0.01). The yield of trainees also improved with every 10 procedures (79, 90 and 95%, p < 0.001) and that of attending physicians with experience (1-25 procedures: 78% yield, 26-50 procedures: 87% yield and 50+ procedures: 90% yield; p < 0.01). Among trainees, failure rates declined steadily. CONCLUSION: EBUS-TBNA yield (malignant and benign) increases with increasing experience amongst experienced bronchoscopists and trainees as early as the first 20-25 procedures. Pulmonary trainees had a rapid decline in failure rates. These findings suggest that in an academic environment a minimum of 20-25 procedures is needed to achieve acceptable yields.

Active asthma and the prevalence of physician-diagnosed COPD.

INTRODUCTION: Despite the considerable overlap of asthma and chronic obstructive pulmonary disease (COPD), the extent to which the two diagnoses are the manifestations of the same disease remains unresolved. We conducted these analyses to evaluate the role of active asthma in the prevalence of physician-diagnosed COPD. METHODS: From 2006 through 2010, 74,209 adults aged 18-99 years and with a history of asthma participated in the Behavioral Risk Factor Surveillance System (BRFSS) Asthma Call-back Survey and responded to interview-administered questionnaires via telephone. We used publicly available data from 71,639 (97%) participants to identify respondents with and without active manifestations of asthma and self-reported, physician-diagnosed COPD. We generated population-weighted estimates of physician-diagnosed COPD prevalence and conducted linear regression to estimate associations between active asthma status and the prevalence of COPD among current smokers, former smokers, and lifetime nonsmokers separately. RESULTS: Physician-diagnosed COPD was reported in an estimated 29% of the population with any history of asthma, including both active and inactive asthma. Age-specific prevalences of physician-diagnosed COPD were consistently higher among adults with active asthma than adults without active asthma. Compared to inactive asthma, active asthma was associated with an 8.3% [95% confidence interval (CI) 6.1, 10.5] higher prevalence of physician-diagnosed COPD among lifetime nonsmokers, a 20.6% (95% CI 18.0, 23.3) higher prevalence among former smokers, and a 26.7% (95% CI 22.5, 30.9) higher prevalence among current smokers. CONCLUSIONS: Among adults with a history of asthma, active manifestations of asthma may play an important role in the epidemiology of COPD.

Diagnosis and management of pancreatic cystic lesions for the non-gastroenterologist.

Although most pancreatic cystic lesions do not progress to cancer, they create concern for patients and their primary care physicians. The lack of consensus guidelines on diagnosis and surveillance of these lesions can lead to a management conundrum. We review current guidelines on diagnosis and management.

Transforming Health Care from Volume to Value: Targeting Essential Therapies for Improved Health.

The healthcare landscape is evolving rapidly due to escalating costs from the traditional fee-for-service model. Value-based care has emerged as a viable solution, and initiatives focus on areas prone to overuse, waste, or high costs, such as advanced imaging and avoidable acute care resource utilization. Improving medication use is an important component of this work, and it requires organizational commitment, interdisciplinary collaboration, and targeted strategies for specific therapeutic areas. This review article discusses the value-based care approach to optimizing medications and blood product prescribing, spotlighting opportunities to reduce the overuse of opioid, antimicrobial, and proton pump inhibitor medications, alongside the underuse of guideline-based medical therapies in managing chronic diseases like coronary artery disease, heart failure, and chronic obstructive pulmonary disease.

Gastroparesis for the nongastroenterologist.

Gastroparesis is a heterogeneous motility disorder characterized by nausea, vomiting, and postprandial fullness. Its diagnosis requires objective documentation of delayed gastric emptying of solid food and exclusion of mechanical obstruction. Its epidemiology is unclear, and the main causes are diabetes mellitus and idiopathic disease. Cardinal symptoms often co-occur. Management involves nutritional assessment, dietary changes, drug evaluation, glycemic control (for patients with diabetes mellitus), and symptom relief. In this review, we explore challenges nongastroenterologists may encounter and how they can use current recommendations to manage patients with gastroparesis.

Management of Clostridioides difficile Infection: Diagnosis, Treatment, and Future Perspectives.

Clostridioides difficile infection is the most common healthcare-associated infection in the United States, with potential life-threatening complications and a significant impact on the costs of care. Antibiotic stewardship as well as discontinuation of chronic acid suppressive therapy are key for its prevention and treatment. Effective infection management requires appropriate interpretation of diagnostic tests, as well as the use of vancomycin and fidaxomicin as first-line treatment. Novel treatments such as Bezlotoxumab, fecal microbiota transplant, and live biotherapeutic products are proven effective in recurrent C. difficile infection and address dysbiosis.
