We describe a case of a 36-year-old man with a history of chronic hepatitis C who presented with abdominal pain 3 days after undergoing a percutaneous ultrasound-guided liver biopsy. Initial investigations revealed a venobiliary fistula with haemobilia and obstructive jaundice with direct bilirubin peaking at 9.2 mg/dL. He underwent an endoscopic retrograde cholangiopancreatography with sphincterotomy and stent placement, bilirubin decreased to 3.7 mg/dL, and the patient was discharged. The patient returned with recurrent abdominal pain and upper gastrointestinal bleeding with haemoglobin of 8.6 g/dL, requiring multiple transfusions. He underwent transcatheter arterial embolisation but continued bleeding. Radiofrequency ablation was pursued and was able to achieve haemostasis. The patient was discharged. The patient returned again with a fever of 39.2 degrees C and was found to have a large right hepatic lobe abscess. The patient underwent abscess drainage with drain placement and was treated with antibiotics for 6 weeks. He followed up in the clinic with resolution of symptoms and infection.

Objectives:KPC-producing Klebsiella pneumoniae are an emerging public health problem around the globe. We defined the combinatorial pharmacodynamics and ability to suppress resistance of two 'old' antibiotics, fosfomycin and colistin, in time-kill experiments and hollow-fibre infection models (HFIM). Methods:Two KPC-2-producing K. pneumoniae isolates were used: one susceptible to both colistin and fosfomycin (KPC 9A: MIC colistin 0.25 mg/L and MIC fosfomycin ≤8 mg/L) and the other resistant to colistin and susceptible to fosfomycin (KPC 5A: MIC colistin 64 mg/L and MIC fosfomycin 32 mg/L). Time-kill experiments assessed an array of colistin and fosfomycin concentrations against both isolates. Colistin and fosfomycin pharmacokinetics from critically ill patients were simulated in the HFIM to define the pharmacodynamic activity of humanized regimens over 5 days against KPC 9A. Results:In time-kill experiments, synergy was demonstrated for all colistin/fosfomycin combinations containing >8 mg/L fosfomycin against the double-susceptible KPC strain, 9A. Synergy versus KPC strain 5A was only achieved at the highest concentrations of colistin (4 mg/L) and fosfomycin (512 mg/L) at 48 h. In the HFIM, colistin or fosfomycin monotherapies resulted in rapid proliferation of resistant subpopulations; KPC 9A regrew by 24 h. In contrast to the monotherapies, the colistin/fosfomycin combination resulted in a rapid 6.15 log 10  cfu/mL reduction of KPC 9A by 6 h and complete suppression of resistant subpopulations until 120 h. Conclusions:Colistin and fosfomycin may represent an important treatment option for KPC-producing K. pneumoniae otherwise resistant to traditional antibiotics.

OBJECTIVE: This study compared health care access, utilization, and functional indicators among adults with and without serious psychological distress (SPD) in the years surrounding implementation of the Patient Portable and Affordable Care Act (ACA). METHODS: Adults ages 18 to 64 from the 2006-2014 National Health Interview Survey (N=207, 853) were examined on 11 access, utilization, and functional indicators: health insurance coverage (health coverage), insufficient money for medications, delay in health care (delay in care), insufficient money for health care, visiting a doctor ten or more times in the past 12 months, change in place of health care, change in place of health care due to insurance, limitations in ability to work, limitations in activities of daily living (ADLs), insufficient money for mental health care, and having seen a mental health care provider. RESULTS: Multivariate models that were adjusted for health coverage and sociodemographic characteristics indicated that compared with adults without SPD, adults with SPD had greater odds of lacking money for medications (AOR=10.0) and health care (AOR=3.1), experiencing delays in care (AOR=2.7), visiting a doctor ten or more times in the past 12 months (AOR=3.2), changing usual place of health care (AOR=1.5), changing usual place of health care because of insurance (AOR=1.5), and experiencing limitations in ADLs (AOR=3.6) and ability to work (AOR=1.8). The proportions of adults with SPD who lacked health coverage and money to buy prescriptions increased during the study period. Although this trend reversed in 2014, the proportion with SPD experiencing barriers remained above 2006 levels. CONCLUSIONS: Health care patterns among adults with SPD require greater attention.

The treatment of hormone hypersecretory syndromes caused by neuroendocrine tumors (NETs) can be a major challenge. NETs originating from the small intestine often secrete serotonin causing flushing, diarrhea and valve fibrosis, leading to dehydration or heart failure in severe cases. NETs from the pancreas can secrete a wider variety of hormones, like insulin, glucagon and gastrin leading to distinct clinical syndromes. Historically mortality in patients with functioning NETs was high due to the complications caused by the hypersecretion of hormones. This has been reduced with several drugs: proton-pump inhibitors decrease acid secretion caused by gastrinomas. Somatostatin analogs can inhibit the secretion of multiple hormones and these are now the cornerstone for treating patients with a gastroenteropancreatic NET. However, peptide receptor radionuclide therapy (PRRT) with radiolabeled somatostatin analogs and everolimus can also decrease symptoms of hypersecretion and increase progression-free survival. Several factors affect the survival in patients with a functioning NET. Complications of hypersecretion negatively impact survival; however, secretion of hormones is also often a sign of a well-differentiated NET and due to the symptoms, functioning NETs can be detected in an earlier stage suggesting a positive effect on prognosis. The effect on survival is also dependent on the type of hormone being secreted. This review aims to study the effect of hormone secretion on the prognosis of NETs with the contemporary treatments options available today.

OBJECTIVES:Classify and describe the policy approaches used by countries to regulate e-cigarettes. METHODS:National policies regulating e-cigarettes were identified by (1) conducting web searches on Ministry of Health websites, and (2) broad web searches. The mechanisms used to regulate e-cigarettes were classified as new/amended laws, or existing laws. The policy domains identified include restrictions or prohibitions on product: sale, manufacturing, importation, distribution, use, product design including e-liquid ingredients, advertising/promotion/sponsorship, trademarks, and regulation requiring: taxation, health warning labels and child-safety standards. The classification of the policy was reviewed by a country expert. RESULTS:The search identified 68 countries that regulate e-cigarettes: 22 countries regulate e-cigarettes using existing regulations; 25 countries enacted new policies to regulate e-cigarettes; 7 countries made amendments to existing legislation; 14 countries use a combination of new/amended and existing regulation. Common policies include a minimum-age-of-purchase, indoor-use (vape-free public places) bans and marketing restrictions. Few countries are applying a tax to e-cigarettes. CONCLUSIONS:A range of regulatory approaches are being applied to e-cigarettes globally; many countries regulate e-cigarettes using legislation not written for e-cigarettes.

PURPOSE: Patient education is critical in ensuring patient compliance and good health outcomes. Fellows must be able to effectively communicate with their patients, delivering enough information for the patient to understand their medical problem and maximize patient compliance. We created an objective structured clinical examination (OSCE) with four liver disease cases to assess fellows' knowledge and ability to inform standardized patients about their clinical condition. METHODS: We developed four cases highlighting different aspects of liver disease and created a four station OSCE: hepatitis B, acute hepatitis C, new diagnosis of cirrhosis, and an end-stage cirrhotic non transplant candidate. The standardized patient (SP) with hepatitis B was minimizing the fact that she could not read English. The acute hepatitis C SP was a nursing student who is afraid that having hepatitis C might jeopardize her career. The SP with the new diagnosis of alcoholic cirrhosis needed to stop drinking, and the end-stage liver disease patient had to grapple with his advanced directives. Twelve fellows from four GI training programs participated. Our focus was to assess the fellows' knowledge about liver diseases and the ACGME competencies of health literacy, shared decision making, advanced directives and goals of care. The goal for the fellows was to communicate effectively with the SPs, and acknowledge that each patient had an emotionally charged issue to overcome. The SPs used a checklist to rate fellow's performance. Faculty and the SPs observed the cases and provided feedback. The fellows were surveyed on their performance regarding the case. RESULTS: The majority of fellows were able to successfully summarize findings and discuss a plan with the patient in the new diagnosis of cirrhosis (76.92%) and hepatitis C case (100%), but were less successful in the hepatitis B (30.77%) and end-of-life case (41.67%). Overall, a small percentage of fellows reflected that they did a good job (22-33%), except at the end-of-life case (67%). The fellows' greatest challenge was trying to cover a lot of information in a single outpatient visit. CONCLUSION: Caring for patients with liver diseases can be complex and time consuming. The patients and fellows' observations were discordant in several areas: for example. the fellows believed they excelled in the end-of-life case, but the SP thought only a small percentage of fellows were able to successfully summarize and discuss the plan. This discrepancy and others highlight important areas of focus in training programs. OSCEs are important to help the fellows facilitate striking the right balance of information delivery and empathy, and this will lead to better patient education, compliance, rapport, and satisfaction.

Objective: Assess the effect of adjunctive CBD for treatment of drug-resistant seizures in Dravet syndrome. Methods: This double-blind, placebo-controlled trial randomized 120 children aged 2-18 years with Dravet syndrome and drug-resistant seizures to receive CBD oral solution 20 mg/kg/ day (n=61) or placebo (n=59) for 14 weeks (2 week titration; 12 week maintenance). The primary endpoint was the percentage change from baseline in convulsive seizures (tonic-clonic, tonic, clonic, and atonic) frequency over the 14-week treatment period. Results: The groups were well-balanced at baseline for demographics. Mean age was 10 years, with 29% of patients <6 years. Patients had previously tried a median 4 AEDs, and were currently taking a median 3 AEDs. Convulsive seizure frequency per month decreased from a median of 12.4 to 5.9 (median reduction of 39%) with CBD versus 14.9 to 14.1 (median reduction of 13%) with placebo (difference between groups of 23%; p=0.012). The proportion of patients with e50% reduction in convulsive seizure frequency was 42.6% with CBD versus 27.1% with placebo (OR=2.0; p=0.078). Adverse events (AEs) occurred in 93.4% of CBD and 74.6% of placebo patients, and were mostly mild or moderate; the most common were somnolence, diarrhea, and decreased appetite. Serious AEs were reported in 16.4% of CBD and 5.1% of placebo patients, and were considered treatment-related in 8.2% of CBD patients, all of whom discontinued CBD. Some elevations in transaminases were noted without elevations of bilirubin; all were on concomitant valproate and all resolved. There were no deaths in the study. Conclusions: In this study, CBD resulted in a significantly greater reduction in convulsive seizure frequency than placebo; adverse events were more frequent with CBD, but it was generally well tolerated

BACKGROUND:Work-related burnout is common in primary care and is associated with worse patient safety, patient satisfaction, and employee mental health. Workload, staffing stability, and team completeness may be drivers of burnout. However, few studies have assessed these associations at the team level, and fewer still include members of the team beyond physicians. OBJECTIVE:To study the associations of burnout among primary care providers (PCPs), nurse care managers, clinical associates (MAs, LPNs), and administrative clerks with the staffing and workload on their teams. DESIGN/METHODS:We conducted an individual-level cross-sectional analysis of survey and administrative data in 2014. PARTICIPANTS/METHODS:Primary care personnel at VA clinics responding to a national survey. MAIN MEASURES/METHODS:Burnout was measured with a validated single-item survey measure dichotomized to indicate the presence of burnout. The independent variables were survey measures of team staffing (having a fully staffed team, serving on multiple teams, and turnover on the team), and workload both from survey items (working extended hours), and administrative data (patient panel overcapacity and average panel comorbidity). KEY RESULTS/RESULTS:There were 4610 respondents (estimated response rate of 20.9%). The overall prevalence of burnout was 41%. In adjusted analyses, the strongest associations with burnout were having a fully staffed team (odds ratio [OR] = 0.55, 95% CI 0.47-0.65), having turnover on the team (OR = 1.67, 95% CI 1.43-1.94), and having patient panel overcapacity (OR = 1.19, 95% CI 1.01-1.40). The observed burnout prevalence was 30.1% lower (28.5% vs. 58.6%) for respondents working on fully staffed teams with no turnover and caring for a panel within capacity, relative to respondents in the inverse condition. CONCLUSIONS:Complete team staffing, turnover among team members, and panel overcapacity had strong, cumulative associations with burnout. Further research is needed to understand whether improvements in these factors would lower burnout.

Formerly incarcerated persons (FIPs) face a disproportionate risk of death and serious illness in the immediate post-release period. Therefore, it is a critical time to initiate community-based care for chronic illnesses and behavioural disorders. Little is known about the unique transitional health and social support needs of FIPs in Louisiana, which has the highest incarceration rate in the world. As the average age of prisoners in the United States rises, the release of older prisoners with chronic conditions will become increasingly common. The aim of this study was to explore the healthcare experiences of FIPs in Louisiana in order to inform delivery of services tailored to this population. This research was done in partnership with a community organisation that advocates for restoration of voting rights to FIPs and helps newly released individuals transition back into society. This organisation identified FIPs in the Greater New Orleans area, and from January to May 2015, we conducted 24 semi-structured, in-person, audio-recorded interviews at the community organisation's transitional living facility. The interviews assessed FIPs' experiences with and barriers to receiving healthcare during and after incarceration. These discussions also explored FIPs' desires for services and attitudes towards health and healthcare. Interviews were transcribed and independently coded by two researchers. Interviewees reported negative experiences with healthcare during incarceration, and limited health guidance during the pre-release process. Post-release concerns included lack of insurance, difficulty accessing care and medication, and interest in learning about healthy lifestyles. Results suggest a need for a formalised system of transitional healthcare for FIPs. Findings are being used to inform a pilot transitional care clinic in New Orleans, Louisiana.
