Objective: The objective of this study was to assess the accuracy of the Substance Abuse and Mental Health Services Administration (SAMHSA) database for patients who use it to seek buprenorphine treatment. Design and Measurements: Buprenorphine providers within a 25-mile radius of the county with the highest drug-related death rates within the 10 states with the highest drug-related death rates were identified and called to determine whether the provider worked there, prescribed buprenorphine, accepted insurance, had appointments, or charged for visits. Results: The number of providers listed in each county ranged from 1 to 166, with 5 counties having <10 providers. In 3 counties no appointments were obtained, and another 3 counties had ≤3 providers with availability. Of the 505 providers listed, 355 providers (70.3%) were reached, 310 (61.4%) of the 505 listings were correct numbers, and 195 (38.6%) of the 505 providers in the listings provided buprenorphine. Of the 173 clinics that provided buprenorphine and were asked about insurance, 131 (75.7%) accepted insurance. Of the 167 clinics that provided buprenorphine and were asked about Medicaid, 105 (62.9%) accepted it. Wait times for appointments ranged from 1 to 120 days, with an average of 16.8 days for those that had a waitlist. Among the 39 providers who reported out-of-pocket costs, the average cost was $231 (range: $90 to $600). One hundred forty of the 505 providers listed in the database had appointments available (27.7%). Three hundred sixty-five of the 505 providers did not have appointments available (72.3%) for various reasons, including the fact that 120 providers (32.9% of the 365 providers) could not be reached, and 137 of the numbers (37.5% of the 365 listed numbers) were wrong. Other reasons appointments could not be obtained included the fact that providers did not treat outpatients, were not accepting new patients, were out of office, or required a referral. Conclusion: Although the SAMHSA buprenorphine practitioner locator is used by patients and providers to locate treatment options, only a small portion of clinicians in the database ultimately offered initial appointments, implying that the database is only marginally useful for patients.

Augmentation of cardiac sympathetic tone during myocardial ischemia has been shown to increase myocardial O(2) demand and infarct size as well as induce arrhythmias. We have previously demonstrated that electroacupuncture (EA) inhibits the visceral sympathoexcitatory cardiovascular reflex. The purpose of this study was to determine the effects of EA on left ventricular (LV) function, O(2) demand, infarct size, arrhythmogenesis, and in vivo cardiac norepinephrine (NE) release in a myocardial ischemia-reperfusion model. Anesthetized rabbits (n = 36) underwent 30 min of left anterior descending coronary artery occlusion followed by 90 min of reperfusion. We evaluated myocardial O(2) demand, infarct size, ventricular arrhythmias, and myocardial NE release using microdialysis under the following experimental conditions: 1) untreated, 2) EA at P5-6 acupoints, 3) sham acupuncture, 4) EA with pretreatment with naloxone (a nonselective opioid receptor antagonist), 5) EA with pretreatment with chelerythrine (a nonselective PKC inhibitor), and 6) EA with pretreatment with both naloxone and chelerythrine. Compared with the untreated and sham acupuncture groups, EA resulted in decreased O(2) demand, myocardial NE concentration, and infarct size. Furthermore, the degree of ST segment elevation and severity of LV dysfunction and ventricular arrhythmias were all significantly decreased (P < 0.05). The cardioprotective effects of EA were partially blocked by pretreatment with naloxone or chelerythrine alone and completely blocked by pretreatment with both naloxone and chelerythrine. These results suggest that the cardioprotective effects of EA against myocardial ischemia-reperfusion are mediated through inhibition of the cardiac sympathetic nervous system as well as opioid and PKC-dependent pathways.

Although rotational parameters by speckle tracking echocardiography (STE) have been previously compared to sonomicrometry and cardiac magnetic resonance imaging, few have examined the relationship between left ventricular (LV) rotational mechanics and intraventricular measures of load-independent contractility, LV stiffness, or ventriculoarterial coupling. The aim of this study was to compare the changes in LV rotational indices to intraventricular pressure–volume (PV) relationships under a range of inotropic states induced by pharmacological interventions, acute ischemia, and changes in preload. In nine pigs, simultaneous echocardiographic imaging and LVPV measurements were performed during pharmacologically induced high or low inotropy and during acute ischemia by ligation of the left anterior descending coronary artery (LAD). Maximal ventricular elastance (Emax), arterial elastance (Ea), ventricular–arterial coupling (Emax/Ea), dP/dt, tau, and other hemodynamic parameters were determined. Dobutamine and esmolol infusions led to inversely correlated changes in hemodynamic measurements of LV function. Apical but not basal rotation and diastolic rotation rate were decreased by esmolol and increased by dobutamine. The LV twist correlates well with Emax (r = 0.83) and Emax/Ea (r = 0.80). Apical diastolic rotation rate also correlates with dP/dtmin (r = −0.63), τ (r = −0.81), and LV stiffness (r = −0.52). LAD ligation decreased systolic and diastolic LV rotation in apical (P < 0.05), but not basal myocardium. Occlusion of the inferior vena cava, to reduce preload, increased apical rotation in systole and diastole. LV rotational parameters measured by STE provide quantitative and reproducible indices of global LV systolic and diastolic function during acute changes in hemodynamics.

While right ventricular (RV) dysfunction has long been known to affect the performance of left ventricle (LV), the mechanisms remain poorly defined. Recently, speckle-tracking echocardiography has demonstrated that preservation of strain and rotational dynamics is crucial to both LV systolic and diastolic function. We hypothesized that alteration in septal strain and rotational dynamics of the LV occurs during acute RV pressure overload (RVPO) and leads to decreased cardiac performance. Seven anesthetized pigs underwent median sternotomy and placement of intraventricular pressure-volume conductance catheters. Two-dimensional echocardiographic images and LV pressure-volume loops were acquired for offline analysis at baseline and after banding of the pulmonary artery to achieve RVPO (>50 mmHg) induced RV dysfunction. RVPO resulted in a significant decrease (P < 0.05) in LV end-systolic elastance (50%), systolic change in pressure over change in time (19%), end-diastolic volume (22%), and cardiac output (37%) that correlated with decrease in LV global circumferential strain (58%), LV apical rotation (28%), peak untwisting (reverse rotation) rate (27%), and prolonged time to peak rotation (17%), while basal rotation was not significantly altered. RVPO reduced septal radial and circumferential strain, while no other segment of the LV midpapillary wall was affected. RVPO decreased septal radial strain on LV side by 27% and induced a negative radial strain from 28 ± 5 to -16 ± 2% on the RV side of the septum. The septal circumferential strain on both LV and RV side decreased by 46 and 50%, respectively, following RVPO (P < 0.05). Our results suggest that acute RVPO impairs LV performance by primarily altering septal strain and apical rotation.

Health care workers are on the front lines of the recent pandemic, facing significant challenges to their physical and mental health. This article details the efforts undertaken by a health care system and two academically affiliated hospital systems to provide emotional support to their frontline staff. The multipronged approach describes coordinating efforts to decrease duplication of services and to increase centralization of information. This included enhancing pathways for faculty, staff, and trainees to obtain individual and group treatment and to have access to high-quality self-help resources. Continuous feedback has been elicited to ensure that efforts are consistent with expressed needs and in turn services undergo modifications as needed. This article seeks to provide an overview of how one health system has thus far approached the important issue of staff support as well as the challenges experienced and lessons learned along the way.

Background Videoscopic left cardiac sympathetic denervation (LCSD) is an adjunct therapy for reduction of arrhythmia-induced events in patients with long-QT syndrome (LQTS). LCSD reduces LQTS-triggered breakthrough cardiac events. The temporal effects of QTc changes post-LCSD have not been studied. Methods We utilized continuous QTc monitoring on 72 patients with LQTS. We evaluated acute and long-term QTc changes in comparison to 12-lead ECG-derived QTc values prior to surgery, 24 hours post-surgery, and at follow up ≥3 months. Results 72 patients underwent LCSD at our institution (46% male, mean age at LCSD was 14 ± 10 years). The mean baseline, pre-LCSD QTc was 505 ± 56 ms, which had decreased significantly at ≥3 months post-LCSD to 491 ± 40 ms (p = 0.001). QTc monitoring revealed that the majority of the cohort (53/72; 74%) had a transient increase >30 ms in QTc from baseline, with an average maximum increase of 72 ± 30 ms. Resolution within 10 ms of baseline or less occurred in 57% (30/53) at 24 hours post-LCSD. Conclusions Although LQTS patients may have a paradoxically increased QTc post-LCSD, the effects are transient in most patients. Importantly, no patients experienced any arrhythmias in the postoperative setting related to this transient rise in QTc.

Our data suggest that LAAO is a reasonable option for stroke prophylaxis in AF when anticoagulation is not an option, and the risk for stroke outweighs the risk of procedural complications. Data were limited with the use of most available devices. To better establish the risk and benefit of LAAO in comparison with standard therapy, more randomized controlled trials are necessary.
