Burnout and Well-Being Among Cardiology Fellowship Program Directors.

OBJECTIVES: The third annual Cardiovascular Diseases (CV) Fellowship Program Directors (PDs) Survey sought to understand burnout and well-being among CV fellowship PDs. BACKGROUND: Physician burnout is a common phenomenon. Data on burnout among cardiologists, specifically CV PDs, remain limited. METHODS: The survey contained 8 questions examining satisfaction, stress, and burnout among CV fellowship PDs. Burnout was defined based on the self-reported presence of ≥1 symptom of burnout, constant feelings of burnout, or complete burnout. RESULTS: Survey response rate was 57%. Most respondents were men (78%) and 54% represented university-based programs. Eighty percent reported satisfaction with their current job as PD, and 96% identified interactions with fellows as a driver of their satisfaction. Forty-five percent reported feeling a great deal of stress from their job. Stress was higher among women PDs, early-career PDs, and PDs of larger and university-based programs. Twenty-one percent reported some symptoms of burnout, and only 36% reported enjoyment without stress or burnout. Rates of enjoyment without stress or burnout were higher among men and late-career PDs, PDs of smaller programs, and PDs of community-based programs. Seventeen percent of PDs reported a high likelihood of resigning in the next year, of which the most common reason was the tasks of PDs were becoming overwhelming. CONCLUSIONS: Most CV fellowship PDs are satisfied with their position, but stress and burnout remain common. Women PDs, early-career PDs, and PDs of larger, university-based programs demonstrate more adverse markers of well-being. Opportunities exist to support CV fellowship PDs in their critical role.

Assessing the utility of pre-operative first pass radionuclide angiography to predict right ventricular failure post left ventricular assist device implantation.

INTRODUCTION: Right ventricular failure (RVF) after left ventricular assist device (LVAD) placement is associated with worse outcomes. We hypothesized that decreased right ventricular (RV) ejection fraction (EF) as well as qualitative assessments of RV function and dilation, as assessed by first pass radionuclide angiography (FPRNA), are associated with an increased risk of RVF following LVAD implantation. METHODS: We retrospectively identified 46 patients from 1/2008 to 11/2017 that underwent FPRNA and LVAD implantation. RVF was defined as requiring inotropes for greater than 14 days after LVAD implantation or requiring a right ventricular assist device. FPRNA-derived variables of RV performance and structure were compared between those that did and did not have RVF post implant. Statistical analyses were performed with Mann-Whitney U tests for ordinal and continuous variables. Fisher's exact tests and Pearson's χ2 tests were used for categorical variables. RESULTS: Eight patients developed RVF after device implantation. The average RV EF on FPRNA was 41.45% in those that did not develop RVF and 40.13% in those that did (P = 0.787). RV dilation (P = 0.896) and global RV function (P = 0.827) by FPRNA were not statistically different between the two groups. CONCLUSION: In patients that required FPRNA for further assessment of RV function prior to LVAD implantation, decreased RV EF, RV dilation and global RV function on FPRNA were not associated with an increased risk of RVF.

Program Directors Survey on Diversity in Cardiovascular Training Programs.

BACKGROUND: Women and minorities are under-represented in cardiovascular disease (CVD) specialties. It remains unknown how characteristics of the CVD learning environment affect diversity and how program directors (PDs) approach these critical issues. OBJECTIVES: The second annual Cardiovascular PD Survey aimed to investigate characteristics of the CVD learning environment that may affect diversity and strategies PDs use to approach these issues. METHODS: The survey contained 20 questions examining U.S.-based CVD PD perceptions of diversity in CVD and related characteristics of the CVD fellowship learning environment. RESULTS: In total, 58% of PDs completed the survey. Responding programs demonstrated geographic diversity. The majority were university-based or -affiliated. A total of 86% of PDs felt diversity in CVD as a field needs to increase, and 70% agreed that training programs could play a significant role in this. In total, 89% of PDs have attempted to increase diversity in fellowship recruitment. The specific strategies used were associated with PD sex and the presence of under-represented minority trainees in the program. PDs identified lack of qualified candidates and overall culture of cardiology as the 2 most significant barriers to augmenting diversity. A majority of programs have support systems in place for minority fellows or specific gender groups, including procedures to report issues of harassment or an unsafe learning environment. PDs identified shared best practices for recruitment and implicit bias training, among others, as important resources in their efforts to support diversity in CVD training. CONCLUSIONS: Diversity is important to CVD PDs. They are striving to increase it in their programs through recruitment and strategies directed toward the fellowship learning environment. The CVD community has opportunities to standardize strategies and provide national resources to support PDs in these critical efforts.

Design of the ocular coil, a new device for non-invasive drug delivery.

Eye drops and ointments are the most prescribed methods for ocular drug delivery. However, due to low drug bioavailability, rapid drug elimination, and low patient compliance there is a need for improved ophthalmic drug delivery systems. This study provides insights into the design of a new drug delivery device that consists of an ocular coil filled with ketorolac loaded PMMA microspheres. Nine different ocular coils were created, ranging in wire diameter and coiled outer diameter. Based on its microsphere holding capacity and flexibility, one type of ocular coil was selected and used for further experiments. No escape of microspheres was observed after bending the ocular coil at curvature which reflect the in vivo situation in human upon positioning in the lower conjunctival sac. Shape behavior and tissue contact were investigated by computed tomography imaging after inserting the ocular coil in the lower conjunctival fornix of a human cadaver. Thanks to its high flexibility, the ocular coil bends along the circumference of the eye. Because of its location deep in the fornix, it appears unlikely that in vivo, the ocular coil will interfere with eye movements. In vitro drug release experiments demonstrate the potential of the ocular coil as sustained drug delivery device for the eye. We developed PMMA microspheres with a 26.5 ± 0.3 wt% ketorolac encapsulation efficiency. After 28 days, 69.9% ± 5.6% of the loaded ketorolac was released from the ocular coil when tested in an in vitro lacrimal system. In the first three days high released dose (48.7% ± 5.4%) was observed, followed by a more gradually release of ketorolac. Hence, the ocular coil seems a promising carrier for ophthalmic drugs delivery in the early postoperative time period.

Diagnostic Accuracy of FDG PET/CT in Suspected LVAD Infections: A Case Series, Systematic Review, and Meta-Analysis.

OBJECTIVES: The purpose of this study was to describe our experience with fluorine-18 fluorodeoxyglucose (FDG) positron emission tomography computed tomography (PET/CT) in diagnosing left ventricular assist device (LVAD) infections and perform a meta-analysis of published studies to determine overall diagnostic accuracy. BACKGROUND: Device-related infections are a common complication of LVADs and are linked to worse outcomes. Diagnosis of LVAD infections remains challenging. FDG PET/CT has demonstrated good diagnostic accuracy in several other infectious conditions. METHODS: This was a single-center, retrospective case series of FDG PET/CT scans in suspected LVAD infection between September 2015 and February 2018. A systematic review of PubMed from database inception through March 2018 was also conducted to identify additional studies. RESULTS: Nineteen FDG PET/CT scans were identified for the retrospective case series. The systematic review identified an additional 3 publications, for a total of 4 studies involving 119 scans assessing diagnostic performance. Axial (n = 36) and centrifugal (n = 83) flow LVADs were represented. Pooled sensitivity was 92% (95% confidence interval [CI]: 82% to 97%) and specificity was 83% (95% CI: 24% to 99%) for FDG PET/CT in diagnosing LVAD infections. Summary receiver-operating characteristic curve analysis demonstrated an AUC of 0.94 (95% CI: 0.91 to 0.95). CONCLUSIONS: FDG PET/CT for suspected LVAD infections demonstrates good diagnostic accuracy, with overall high sensitivity but variable specificity.

Multidisciplinary team meeting and EUSOMA quality indicators in breast cancer care: A French regional multicenter study.

INTRODUCTION: We evaluate breast cancer (BC) pathway at a regional level including public, private and university institutions. We assessed the quality of multidisciplinary team meetings (MTM) and compliance with a panel of European high-quality indicators (EUSOMA QIs). METHODS: We conducted a retrospective multicenter (n = 20) study in the largest health care region in France. Between January and April 2015, we included all patients discussed at an MTM after a diagnosis of BC (n = 619). We analyzed quality of MTM by assessing the quorum, the reliability of data transcription and the exhaustivity of pre-therapeutic MTM. We then analyzed the compliance with a selected panel of 16 EUSOMA QIs. RESULTS: During MTM discussion, data were more than 95% consistent with medical records for 9/11 items. Pre-operative tumor histology (90.6%) and post-operative resection margins (84.3%) were the least concordant between medical records and MTM. Minimum standards as defined by EUSOMA were reached for 11/16 QIs, but not reached for pathology reports in non-invasive BC (78.2%), proportion of exclusive sentinel lymph node biopsies in patients with clinically negative axilla (85.2%), performing adjuvant chemotherapy (76.6%), and proportion of patients discussed in pre-therapeutic and post-operative MTM (63.5%). CONCLUSIONS: In this multicentric study evaluating the quality of BC care with a representative sample of institutions, compliance with EUSOMA indicators was satisfactory for all type of institutions. However, too few patients were discussed in pre-therapeutic MTM (especially in non-university hospitals 43.7% [39.4-48.1]) versus 88.7% for others [82.2-95.1]) and data transcription was likely responsible for up to 15% of discordance.

Microcracks in subchondral bone plate is linked to less cartilage damage.

OBJECTIVES: Osteoarthritis (OA) is a disease of the whole joint characterized by cartilage loss and subchondral bone remodeling. The role of microcracks in cartilage integrity and subchondral bone homeostasis is not fully understood. The main goal of this work was to evaluate microcrack density in both calcified cartilage and subchondral bone plate in relation to cartilage damage in humans and to better define the association of microcracks and osteocyte density in subchondral bone. METHODS: We investigated 18 bone cores from cadaveric human knees that were stained with En-Bloc Basic Fuchsin. We quantified microcrack density, osteocyte density, cartilage surfaces and cartilage damage. The presence of microcracks was confirmed for each bone core by scanning electron microscopy. Finally, trabecular subchondral bone parameters were measured by micro-CT. RESULTS: Microcracks were detected in both calcified cartilage and subchondral bone plate. The density of microcracks in both calcified cartilage (CC) and subchondral bone plate (SBP) was negatively correlated with cartilage damage (r = -0.45, p < 0.05). The presence of microcracks in SBP was associated with a lower histological OA score. Osteocytes formed a dendrite network that abruptly stopped at the border of calcified cartilage. Osteocyte density in subchondral bone plate was increased in the presence of microcracks in calcified cartilage. CONCLUSIONS: Subchondral bone plate microcracks might be required for maintaining cartilage homeostasis. Microcracks in calcified cartilage may trigger osteocyte density in subchondral bone plate with subsequent regulation of subchondral bone remodeling to prevent cartilage damage.

Evolution and duration of nodules in severe nodular acne on the back: results from a four-week non-interventional, prospective study.

BACKGROUND: Severe nodular acne is characterized by inflammatory nodules and scarring. Their natural evolution and duration are insufficiently investigated. AIM: To investigate the evolution and duration of untreated acne nodules. METHODOLOGY: Four-week, single-centre, non-interventional, prospective study in subjects with severe nodular acne on the back. Nodule evolution and duration was assessed using standardized photographs taken twice weekly. RESULTS: Data from 23 subjects were evaluable. Mean age was 25.1 ± 4.9 years, 87% were males, and mean acne duration was 9.7 ± 6.7 years. At baseline, the overall total nodule count was 132 (mean number: 5.7 ± 3.0 nodules/subject). Among others, the following two main pathways were observed: nodules evolving directly into atrophic scars (31.8%) and nodules evolving towards papules into atrophic scars (37.9%). After 4 weeks, 77.3% of baseline nodules had evolved into atrophic scars. After baseline visit, a total of 247 new nodules (3.1 ± 2.2 nodules/week/subject) with a mean duration of 4.9 ± 2.6 days were observed. The mean duration of new nodules was significantly longer in subjects (n = 16) with ≥6 new nodules compared to subjects (n = 7) with <6 new nodules (5.2 ± 1.4 vs. 3.6 ± 0.8 days; P = 0.008)). There was no correlation between the number of new nodules and acne duration or with the number of baseline nodules. CONCLUSION: This study documents the natural nodule evolution and duration over 4 weeks and showed in 23 patients the scarring potential of untreated severe nodular acne of the back.

Efficacy of a global supportive skin care programme with hydrotherapy after non-metastatic breast cancer treatment: A randomised, controlled study.

This study investigated the efficacy of post-treatment hydrotherapy as supportive care for management of persistent/long-lasting dermatologic adverse events (dAEs) induced in breast cancer survivors by adjuvant therapy, and its impact on quality of life (QoL). Patients in complete remission after standardised (neo)adjuvant chemotherapy, surgery and radiotherapy combination treatment for infiltrating HR+/HER2-breast carcinoma were enrolled in this randomised, multicentre controlled study 1-5 weeks after completing radiotherapy. The control group (CG, n = 33) received best supportive care and the treatment group (HG, n = 35) received 3-weeks of specific hydrotherapy. The primary criterion was change in QoL (QLQ-BR23) after hydrotherapy. Clinical grading of dAEs, cancer-related QoL (QLQ-C30), dermatologic QoL (DLQI) and general psychological well-being (PGWBI) were assessed. Significant dAEs were found at inclusion in both groups (n = 261). Most items showed significantly greater improvement in the HG versus CG group: QLQ-BR23 (breast [p = .0001] and arm symptoms [p = .0015], systemic therapy side effects [p = .0044], body image [p = .0139]), some dAE grading, DLQI (p = .0002) and PGWBI (p = .0028). Xerosis (88% of patients at inclusion) completely healed in all HG patients. Specific hydrotherapy is an effective supportive care for highly prevalent and long-lasting dAEs occurring after early breast cancer treatment, including chemotherapy, and leads to improved QoL and dermatologic toxicities.

Envenomation by Micrurus psyches in French Guiana.

We report here the first known envenomation by Micrurus psyches, the so-called Carib coral snake, which occurred on April 2016 in the surroundings of Saint-Laurent-du-Maroni, Western French Guiana. Besides local neurological symptoms, it featured unexpected electrocardiogram changes, which were emergence of a first-degree atrioventricular block and biphasic T waves, both transient. NewWorld elapid venoms were not known for being cardiotoxic so far. The possible reasons of this cardiac injury are discussed.

Current Perspectives on Systemic Hypertension in Heart Failure with Preserved Ejection Fraction.

Heart failure with preserved ejection fraction (HFpEF) is a prevalent but incompletely understood syndrome. Traditional models of HFpEF pathophysiology revolve around systemic HTN and other causes of increased left ventricular afterload leading to left ventricular hypertrophy (LVH) and diastolic dysfunction. However, emerging models attribute the development of HFpEF to systemic proinflammatory changes secondary to common comorbidities which include HTN. Alterations in passive ventricular stiffness, ventricular-arterial coupling, peripheral microvascular function, systolic reserve, and chronotropic response occur. As a result, HFpEF is heterogeneous in nature, making it difficult to prescribe uniform therapies to all patients. Nonetheless, treating systemic HTN remains a cornerstone of HFpEF management. Antihypertensive therapies have been linked to LVH regression and improvement in diastolic dysfunction. However, to date, no therapies have definitive mortality benefit in HFpEF. Non-pharmacologic management for HTN, including dietary modification, exercise, and treating sleep disordered breathing, may provide some morbidity benefit in the HFpEF population. Future research is need to identify effective treatments, perhaps in more specific subgroups, and focus may need to shift from reducing mortality to improving exercise capacity and symptoms. Tailoring antihypertensive therapies to specific phenotypes of HFpEF may be an important component of this strategy.

The value of a poison control center in preventing unnecessary ED visits and hospital charges: A multi-year analysis.

OBJECTIVE: The purpose of this study is to determine the economic value of the Utah Poison Control Center (UPCC) by examining its contribution to the reduction of unnecessary emergency department (ED) visits and associated charges across multiple years. METHODS: A multi-year (2009-2014) analysis of cross-sectional data was performed. Callers were asked what they would do for a poison emergency if the UPCC was not available. Healthcare charges for ED visits averted were calculated according to insurance status using charges obtained from a statewide database. RESULTS: Of the 10,656 survey attempts, 5018 were completed. Over 30,000 cases were managed on-site each year. Using the proportion of callers who noted they would call 911, visit an ED, or call a physician's office, between 20.0 and 24.2 thousand ED visits were potentially prevented each year of the survey. Between $16.6 and $24.4 million dollars in unnecessary healthcare charges were potentially averted annually. CONCLUSIONS: Compared to the cost of operation, the service UPCC provides demonstrates economic value by reducing ED visits and associated charges. As the majority of patients have private insurance, the largest benefit falls to private payers.

Acute oral 18-methoxycoronaridine (18-MC) decreases both alcohol intake and IV nicotine self-administration in rats.

The ibogaine derivative 18-methoxycoronaridine (18-MC) has been found to decrease self-administration of morphine, nicotine and alcohol in rats after systemic injection. However oral dosing is the preferred route clinically. The current study evaluated the effect of oral 18-MC dosing in rats on alcohol and nicotine self-administration. For the nicotine study, young adult female Sprague-Dawley rats were fitted with IV jugular infusion catheters and trained for nicotine self-administration in 45min. sessions. At weekly intervals they were administered by oral gavage doses of 18-MC (0, 10, 20 and 40mg/kg) following a repeated measures counterbalanced design twice. Acute oral 18-MC, at the 40mg/kg dosage, significantly reduced nicotine self-administration. There was a differential effect of 18-MC with rats above or below the median level of nicotine self-administration during the pretreatment baseline performance. Rats with lower baseline performance showed a significant reduction in nicotine self-administration with the 40mg/kg dosage, while those in the higher baseline group did not show a significant effect of 18-MC. In alcohol studies, the effects of the same doses of 18-MC were tested in both male and female alcohol preferring (P) rats that had free access to water and alcohol (10% v/v) 6h/day. The results show that 18-MC dose-dependently reduced alcohol intake in both male and female rats. All doses caused significant reductions in alcohol self-administration. These data reinforce previous findings that 18-MC is significantly effective in reducing alcohol intake and nicotine self-administration. The finding that 18-MC is also effective orally makes it advantageous for further development as a possible new therapy for treating alcoholism as well as smoking addiction.
