Patient and physician factors contributing to polypharmacy among older patients.

OBJECTIVE: Polypharmacy, or use of multiple medications, is associated with patient factors. Less is known regarding variation in polypharmacy by individual physicians. The objective of this study was to assess patient and physician factors associated with polypharmacy among older patients. METHODS: This is a cross-sectional study of patients aged ≥65 years with a primary care visit at Cleveland Clinic Health System in 2015 and their physicians. We collected patient demographics, comorbidities and current medications from the electronic health record, including potentially inappropriate medications (PIMs). We used mixed effects linear regression to estimate adjusted differences in the number of medications by patient factors. We generated adjusted prescribing rates for individual physicians and assessed differences in physician performance on quality measures by their prescribing rate. RESULTS: Our study included 44,570 patients who were prescribed an average of 6.8 medications (standard deviation: 4.0) by 701 physicians. Female sex, higher BMI, having Medicaid insurance, current or former smoking status, comorbidities and seeing a specialist were associated with number of medications. Age was not. Among 267 physicians who saw ≥20 study-eligible patients, the adjusted mean number of medications per patient ranged from 5.2 to 9.6. Compared to physicians who prescribed above the mean, lower prescribing physicians performed significantly better on medication reconciliation (p = .007) and hypertension control (p < .001) and prescribed fewer PIMs (p < .001). CONCLUSIONS: Individual physicians varied in their prescribing practices, even after adjusting for patient demographic and clinical characteristics. Interventions to reduce polypharmacy in older adults should target high prescribing physicians, as physician behavior is more actionable than patient factors.

Lyme Carditis: A Reversible Cause of Acquired Third-Degree AV Block.

BACKGROUND Lyme borreliosis, caused by spirochetes of the Borrelia burgdorferi genospecies complex, is the most commonly reported tickborne infection in North America and those infected may present with cutaneous, cardiac, articular, and neuropsychiatric abnormalities. The protean nature of many of its clinical manifestations presents a diagnostic conundrum. Lyme disease can affect the heart, albeit rarely, with cardiac abnormalities usually manifesting as varying degrees of heart block or arrhythmias. CASE REPORT We present a case of complete heart block in a young man who participated in outdoor activities in a Lyme-endemic area and developed fatigue and palpitations weeks after a flu-like illness. He noticed that his heart rate was low; he had an intermediate suspicious index in Lyme carditis (SILC) score with positive Lyme serologies. His initial electrocardiogram when he presented to the emergency department showed a complete heart block. In this case, he was successfully managed with intravenous ceftriaxone, amoxicillin, and a transcutaneous pacemaker, obviating the need for a permanent pacemaker. CONCLUSIONS Electrocardiographic changes such as heart block and arrhythmias with or without symptoms may be the initial manifestation of Lyme carditis in a patient who may or may not remember a tick bite or have a typical skin rash. The SILC score may assist in recognizing these cases and prompt initiation of antibiotics usually leads to the resolution of these electrocardiographic abnormalities and symptoms that may be present.

Pneumonia and alcohol use disorder: Implications for treatment.

Patients with alcohol use disorder (AUD) are at higher risk of pneumonia and of poor outcomes. This article reviews the etiology of pneumonia in patients with AUD, its impact on mortality and resource utilization, and its implications for treatment.

Weil's Disease: A Rare Cause of Jaundice.

Weil's disease is a complication of untreated leptospirosis and can be fatal. Awareness of leptospirosis and its hepatic manifestations are limited. We report the case of a 50-year-old man with gastrointestinal symptoms and a cholestatic pattern of liver injury diagnosed with Weil's disease. The patient showed remarkable improvement after treatment with appropriate antibiotics with normalization of liver function in one month. This case highlights the importance of recognizing leptospirosis and its myriad presentations.

Assessment of Physician Priorities in Delivery of Preventive Care.

Importance: Primary care physicians have limited time to discuss preventive care, but it is unknown how they prioritize recommended services. Objective: To understand primary care physicians' prioritization of preventive services. Design, Setting, and Participants: This online survey was administered to primary care physicians in a large health care system from March 17 to May 12, 2017. Physicians were asked whether they prioritize preventive services and which factors contribute to their choice (5-point Likert scale). Results were analyzed from July 8, 2017, to September 19, 2019. Exposures: A 2 × 2 factorial design of 2 hypothetical patients: (1) a 50-year-old white woman with hypertension, type 2 diabetes, hyperlipidemia, obesity, a 30-pack-year history of smoking, and a family history of breast cancer; and (2) a 45-year-old black man with hypertension, hyperlipidemia, obesity, a 30-pack-year history of smoking, and a family history of colorectal cancer. Two visit lengths (40 minutes vs 20 minutes) were given. Each patient was eligible for at least 11 preventive services. Main Outcomes and Measures: Physicians rated their likelihood of discussing each service during the visit and reported their top 3 priorities for patients 1 and 2. Physician choices were compared with the preventive services most likely to improve life expectancy, using a previously published mathematical model. Results: Of 241 physicians, 137 responded (57%), of whom 74 (54%) were female and 85 (62%) were younger than 50 years. Physicians agreed they prioritized preventive services (mean score, 4.27 [95% CI, 4.12-4.42] of 5.00), mostly by ability to improve quality (4.56 [95% CI, 4.44-4.68] of 5.00) or length (4.53 [95% CI, 4.40-4.66] of 5.00) of life. Physicians reported more prioritization in the 20- vs 40-minute visit, indicating that they were likely to discuss fewer services during the shorter visit (median, 5 [interquartile range {IQR}, 3-8] vs 11 [IQR, 9-13] preventive services for patient 1, and 4 [IQR, 3-6] vs 9 [IQR, 8-11] for patient 2). Physicians reported similar top 3 priorities for both patients: smoking cessation, hypertension control, and glycemic control for patient 1 and smoking cessation, hypertension control, and colorectal cancer screening for patient 2. Physicians' top 3 priorities did not usually include diet and exercise or weight loss (ranked in their top 3 recommendations for either patient by only 48 physicians [35%]), although these were among the 3 preventive services most likely to improve life expectancy based on the mathematical model. Conclusions and Relevance: In this survey study, physicians prioritized preventive services under time constraints, but priorities did not vary across patients. Physicians did not prioritize lifestyle interventions despite large potential benefits. Future research should consider whether physicians and patients would benefit from guidance on preventive care priorities.

The Effect of Starting the Protein-Sparing Modified Fast on Weight Change over 5 years.

BACKGROUND: Ketogenic diets have been highlighted as a way to lose weight while experiencing reduced hunger. The protein-sparing modified fast (PSMF) induces ketosis but may be difficult to maintain. OBJECTIVE: To track weight loss for individuals initiating PSMF versus all other diets (e.g., balanced, high protein) for up to 5 years. DESIGN: Retrospective cohort study PARTICIPANTS: Adults who discussed the PSMF with a clinician between 2007 and 2014 INTERVENTION: Initiating the PSMF diet versus other diets MEASURES: The main outcome was percent weight change up to 5 years. Demographic and health data were collected using electronic health records. We fit regression models including age, sex, race, insurance, new medication prescriptions, and specialist visit to identify the effect of PSMF diet on percent weight change. We grouped patients by percent weight change at each year (≥ 5% loss, 4% loss to 4% gain, ≥ 5% gain) and used Pearson χ2 tests to compare proportions. RESULTS: Of 1,403 eligible patients, 879 (63%) started the PSMF. The PSMF group was slightly younger (52 vs. 54 years, p < 0.01) and had a higher body mass index (41.9 kg/m2 vs. 40.4 kg/m2, p < 0.001). In the adjusted analysis, the PSMF group averaged 3% more weight loss than the other group over the 5-year follow-up (95% CI - 3.5, - 2.0, p < 0.001). PSMF patients lost more weight initially, but by year 4, there was no difference between diets (1.6% versus 1.3%, PSMF versus other diets, p = 0.12). Patients starting the PSMF were more likely to experience ≥ 5% weight loss at 1 year (55% vs 20%, p < 0.001) and 3 years (33% vs. 23% p < 0.05), but not 5 years (34% vs 29%, p = 0.16, PSMF versus other diets, respectively). CONCLUSIONS: In clinical practice, the PSMF achieves rapid weight loss in the first 6 months, but only a small percentage of patients maintained significant weight loss long term.

Obesity Does Not Impact Outcomes or Rates of Gastroesophageal Reflux After Peroral Endoscopic Myotomy in Achalasia.

BACKGROUND: Outcomes of laparoscopic Heller myotomy in obese patients with achalasia are suboptimal along with the increased risk of gastroesophageal reflux disease (GERD). The impact of obesity on treatment success and GERD after peroral endoscopic myotomy (POEM) are not well known. Hence, our study aims were to compare the clinical outcomes and rates of GERD after POEM in nonobese versus obese patients with achalasia. METHODS: Chart review of all achalasia patients who underwent POEM at our institution between April 2014 and June 2018. Patients with timed barium esophagram (TBE) and high-resolution esophageal manometry (HREM) before POEM along with post-POEM TBE, HREM, and esophageal pH study were included. Patients were categorized into 2 groups, nonobese (body mass index <30 kg/m) and obese (body mass index ≥30 kg/m). Patient demographics, TBE, HREM, pH study findings, and Eckardt scores were compared between the 2 groups. RESULTS: A total of 89 patients (46 nonobese; 43 obese) met the study criteria. There were no significant differences in age, gender, achalasia subtype, operative time, length of stay and complication rates between the 2 groups. Treatment success (Eckardt score ≤3) was similar in both groups (97.7% nonobese vs. 92.7% obese, P=0.35). Abnormal DeMeester scores on pH study (>14.72) were similar in nonobese and obese patients (58.7% vs. 46.5%, P=0.25). Symptomatic GERD was also similar in both groups (17.8% in nonobese vs. 20% in obese, P=0.79). CONCLUSIONS: POEM is an equally safe and effective treatment option for both nonobese and obese patients with achalasia in the short-term. Interestingly, POEM does not lead to higher rates of GERD in obese compared with nonobese patients.

The Colonic Single Stripe Sign: A Case of Ischemic Colitis.

Sudden, transient reduction in the blood flow especially in the "watershed" regions of the colon can lead to intestinal ischemia causing a decrease in the delivery of oxygen and nutrients to the intestinal wall. Patients with ischemic colitis often have elevated white blood cell counts, serum lactate, and serum amylase levels. Colonoscopy can confirm the diagnosis of ischemia and the findings include edematous, friable mucosa, erythema with interspersed pale areas, scattered hemorrhagic erosions or linear ulcerations. A single, linear ulcer running along the anti-mesenteric colonic wall, "single-stripe sign"- favors the diagnosis of ischemic colitis. Management of mild and moderate colonic ischemia includes supportive care with bowel rest, gastric suction for associated ileus, fluid-electrolyte balance, and broad-spectrum antibiotics. Patients with severe colonic ischemia may require abdominal exploration and colectomy.

Association Between Alcohol Use Disorders and Outcomes of Patients Hospitalized With Community-Acquired Pneumonia.

Importance: Patients with alcohol use disorder (AUD) are at elevated risk of developing pneumonia, but few studies have assessed the outcomes of pneumonia in patients with AUD. Objectives: To compare the causes, treatment, and outcomes of pneumonia in patients with and without AUD and to understand the associations of comorbid illnesses, alcohol withdrawal, and any residual effects due to alcohol itself with patient outcomes. Design, Setting, and Participants: A retrospective cohort study was conducted of 137 496 patients 18 years or older with pneumonia who were admitted to 177 US hospitals participating in the Premier Healthcare Database from July 1, 2010, to June 30, 2015. Statistical analysis was conducted from October 27, 2017, to August 20, 2018. Exposure: Alcohol use disorders identified from International Classification of Diseases, Ninth Revision, Clinical Modification codes. Main Outcomes and Measures: Pneumonia cause, antibiotic treatment, inpatient mortality, clinical deterioration, length of stay, and cost. Associations of AUD with these variables were studied using generalized linear mixed models. Results: Of 137 496 patients with community-acquired pneumonia (70 358 women and 67 138 men; mean [SD] age, 69.5 [16.2] years), 3.5% had an AUD. Patients with an AUD were younger than those without an AUD (median age, 58.0 vs 73.0 years; P < .001), more often male (77.3% vs 47.8%; P < .001), and more often had principal diagnoses of aspiration pneumonia (10.9% vs 9.8%; P < .001), sepsis (38.6% vs 30.7%; P < .001), or respiratory failure (9.3% vs 5.5%; P < .001). Their cultures more often grew Streptococcus pneumoniae (43.7% vs 25.5%; P < .001) and less frequently grew organisms resistant to guideline-recommended antibiotics (25.0% vs 43.7%; P < .001). Patients with an AUD were treated more often with piperacillin-tazobactam (26.2% vs 22.5%; P < .001) but equally as often with anti-methicillin-resistant Staphylococcus aureus agents (32.9% vs 31.8%; P = .11) compared with patients without AUDs. When adjusted for demographic characteristics and insurance, AUD was associated with higher mortality (odds ratio, 1.40; 95% CI, 1.25-1.56), length of stay (risk-adjusted geometric mean ratio, 1.24; 95% CI, 1.20-1.27), and costs (risk-adjusted geometric mean ratio, 1.33; 95% CI, 1.28-1.38). After additional adjustment for differences in comorbidities and risk factors for resistant organisms, AUD was no longer associated with mortality but remained associated with late mechanical ventilation (odds ratio, 1.28; 95% CI, 1.12-1.46), length of stay (risk-adjusted geometric mean ratio, 1.04; 95% CI, 1.01-1.06), and costs (risk-adjusted geometric mean ratio, 1.06; 95% CI, 1.03-1.09). Models segregating patients undergoing alcohol withdrawal showed that poorer outcomes among patients with AUD were confined to the subgroup undergoing alcohol withdrawal. Conclusions and Relevance: This study suggests that, compared with hospitalized patients with community-acquired pneumonia but without AUD, those with AUD less often harbor resistant organisms. The higher age-adjusted risk of death among patients with AUD appears to be largely attributable to differences in comorbidities, whereas greater use of health care resources may be attributable to alcohol withdrawal.

Outcomes of endoscopic submucosal dissection in esophageal adenocarcinoma staged T1bN0 by endoscopic ultrasound in non-surgical patients.

Patients with esophageal adenocarcinoma (EAC) invading submucosa (T1b) are traditionally treated with esophagectomy and with chemoradiotherapy in poor surgical patients. Endoscopic submucosal dissection (ESD) has emerged as an alternative treatment in these patients. In this case series, we analyzed the outcomes of ESD in EAC staged T1bN0 by endoscopic ultrasound (EUS). Patients with EAC staged T1bN0M0 by EUS and PET scan who underwent ESD by a single operator (MS) between 2014 and 2017 at our institution were included. They were deemed as poor surgical candidates and ESD was considered as the most appropriate treatment option after a multi-disciplinary evaluation. There were 8 patients (male =5; female =3) with average age of 70.5 years old (range, 53-84 years old). ESD was completed in 7 and aborted in 1 patient due to tumor invasion into muscularis propria. En bloc, R0 and curative resection rates were 86% (6/7), 86% (6/7) and 71% (5/7) respectively. Final histology was intramucosal (T1a) in 4 and submucosal (T1b) in 3. One patient (14%) developed stricture requiring balloon dilation. Mean follow-up duration was 10 months (range, 3-15 months) and 71% (5/7) remain in clinical remission. Two patients required CRT, one with T1a who developed recurrence and another with T1b with lymphovascular invasion. In poor surgical candidates, ESD was associated with accurate staging and favorable outcomes in EAC staged T1bN0 by EUS. We suggest considering ESD in EAC staged T1bN0 for accurate histological staging, curative potential and also to help determine further course of treatment.

Obstructive Sleep Apnea and the Liver.

Nonalcoholic fatty liver disease (NAFLD), a disorder of altered metabolic pathways, is increasing worldwide. Recent studies established obstructive sleep apnea (OSA) and chronic intermittent hypoxia (CIH) as NAFLD risk factors. Studies have ascertained that CIH is independently related to NAFLD. Continuous positive airway pressure (CPAP) shows inconsistent results regarding its efficacy in improving NAFLD. Observational, longer duration CPAP therapy studies have shown positive outcomes, whereas shorter duration, randomized controlled trials have shown no benefit. A multifaceted approach to NAFLD management with sufficiently longer duration of CPAP therapy may be beneficial in patients with moderate to severe OSA.

Esophageal Third Space Endoscopy: Recent Advances.

PURPOSE OF THE REVIEW: The novel concept of third space endoscopy was first applied to humans in 2008 for the management of achalasia through peroral endoscopic myotomy (POEM) procedure. Over the ensuing 10 years, this revolutionary procedure, which started in Japan, has been adopted and mastered by surgeons and gastroenterologists across the globe. In this article, we review the recent innovations and applications of third space endoscopy in the management of esophageal disorders. RECENT FINDINGS: With experience and innovation, the application of third-space endoscopy has extended beyond achalasia, and currently, it is used in the management of other esophageal disorders including, spastic esophageal disorders, subepithelial tumors, complete esophageal obstruction, and esophageal diverticula. The recent advances in third space endoscopic procedures have not only permitted endoscopic access to places, previously thought impossible, but also enabled the precision of surgery along with reduced peri-operative morbidity due to its minimally invasive nature. While short- and mid-term outcome studies have shown excellent results, we eagerly await the long-term outcome studies before these procedures could be established as the procedures of choice.

Population-Based Trends in Prevalence of Nonalcoholic Fatty Liver Disease in US Adults With Type 2 Diabetes.

Type 2 diabetes (T2D) affects more than 9% of U.S. adults.1 Nonalcoholic fatty liver disease (NAFLD) has been recognized as a common co-morbidity in T2D. However, most previous epidemiologic studies have been subject to ascertainment and selection bias or had small sample sizes. No recent studies have examined trends of the burden of NAFLD in diabetic patients. Using noninvasive scores and the National Health and Nutrition Examination Survey (NHANES), we aimed to estimate the population-based trends in prevalence of NAFLD-associated comorbidities in U.S. adults with T2D.

Peroral endoscopic myotomy leads to higher rates of abnormal esophageal acid exposure than laparoscopic Heller myotomy in achalasia.

BACKGROUND AND AIMS: Peroral endoscopic myotomy (POEM) may be associated with higher rates of gastroesophageal reflux disease (GERD) than laparoscopic Heller's myotomy with fundoplication (LHM), since POEM is not combined with a fundoplication. However, peri-esophageal anti-reflux barriers are preserved in POEM, which might prevent GERD. Hence, we sought to compare the objective esophageal pH study findings in achalasia patients after POEM and LHM. METHODS: Achalasia patients undergoing POEM from 2014 to 2015 at our institution were matched 1:3 with LHM patients using propensity score matching. Demographics, prior interventions, pre-treatment and 2-month post-treatment timed barium esophagram (TBE), high-resolution esophageal manometry (HREM) and 24-h esophageal pH study findings were compared between the two groups. RESULTS: Thirty-one patients in the POEM group and 88 patients in the LHM group were included. Larger proportion of POEM patients had prior interventions for achalasia as compared to LHM patients (overall: 71% vs. 44.3%; p = 0.012). Esophageal acid exposure was significantly higher in POEM as compared to LHM patients (abnormal total acid exposure: 48.4% vs. 13.6%; p < 0.001, abnormal DeMeester score 54.8% vs. 17.4%; p = 0.005 respectively). In sub-group analysis, similar results were noted on 24-h pH study after exclusion of the POEM patients with prior LHM and corresponding matches. There was no significant difference in the rate of GERD symptoms between POEM and LHM. There was no significant correlation between the post-treatment basal lower esophageal sphincter pressure and integrated relaxation pressure with abnormal acid exposure in either POEM or LHM. CONCLUSIONS: In patients with achalasia, POEM leads to significantly higher rates of abnormal esophageal acid exposure, without an increase in the rate of GERD symptoms, when compared to LHM with fundoplication. Interestingly, prior LHM has no impact on post-POEM pH study findings. Potential of increased esophageal acid exposure and possible consequences should be discussed with all patients prior to POEM. Further studies are needed to determine the long-term effects of increased acid exposure after POEM.

Peroral Endoscopic Myotomy Is Effective for Patients With Achalasia and Normal Lower-Esophageal Sphincter Relaxation Pressures.

Increased lower esophageal sphincter integrated relaxation pressure (LES-IRP) is a cardinal feature of achalasia. However, some patients with characteristic features of achalasia have normal LES-IRP.1,2 The efficacy of peroral endoscopic myotomy (POEM) in achalasia patients with normal LES-IRP is not well known. Hence, we aimed to compare POEM outcomes in achalasia patients with normal (<15 mm Hg) and increased (≥15 mm Hg) LES-IRP.

Temporal trends in utilization and outcomes of endoscopic retrograde cholangiopancreatography in acute cholangitis due to choledocholithiasis from 1998 to 2012.

BACKGROUND AND AIMS: Expeditious endoscopic retrograde cholangiopancreatography (ERCP) in acute cholangitis with biliary decompression is associated with better outcomes. In this study, we evaluated the temporal trends of ERCP utilization and healthcare outcomes among patients hospitalized with acute cholangitis due to choledocholithiasis (CDC) from 1998 to 2012. METHODS: We identified patients with a combined diagnosis of cholangitis and choledocholithiasis from the national inpatient sample database. The temporal trends of ERCP usage and outcomes were analyzed. Based on timing of the procedure, we arbitrarily divided ERCPs into urgent (<24 h), early(24-48 h), and delayed ERCP(>48 h) groups. In addition, trends in length of stay (LOS), hospital charges, and in-hospital mortality rates were evaluated. RESULTS: In-patient admissions for CDC increased by 105.7%. Overall ERCP rate also increased significantly from 66.5 ± 2.3% in 1998 to 80.3 ± 0.93% in 2012, particularly after 2006-2007. There was a significant increase in proportion of urgent and early ERCPs. In the early ERCP group, there was a significant decrease in LOS (6.4 ± 0.43 days in 1998 to 5.8 ± 0.24 days in 2012) and mortality rate (2.4 ± 1.4% in 1998 to 0.33 ± 0.33% in 2012). Hospital charges increased in all ERCP groups, but most significantly in delayed ERCP group ($20,448 ± 1611 in 1998 to $90,566 ± 6122 in 2012). CONCLUSION: In-patient admissions for CDC and ERCP rates have increased significantly, particularly evident after 2006-2007. This may be attributed to increasing incidence of gallstones and wider implementation of Tokyo guidelines for the management of acute cholangitis. In-hospital morality and LOS reduced significantly in early ERCP group, whereas hospital charges increased most significantly in delayed ERCP group.
