The Emergence of Bromazolam in Jefferson County AL. A Case Series.

Postmortem toxicology is an ever-changing landscape presenting challenges for toxicologists and medical examiners. Trends can vary for certain benzodiazepines. While diazepam use tends to remain constant, alprazolam and clonazepam ebb and flow depending on prescription trends and street popularity. Novel benzodiazepines like etizolam vary in casework depending on legal restrictions and black-market availability. In May 2022, the first case of the designer benzodiazepine, bromazolam, was detected in Jefferson County Coroner/Medical Examiner's Office (JCCMEO) casework. Between then and December of 2023, an additional nine cases have been observed. Bromazolam, is the brominated analog of the low dose benzodiazepine alprazolam and is likely similar in potency. As bromazolam is a potent benzodiazepine, low concentrations of this novel drug are likely to contribute to CNS depression in opioid overdose cases. We present ten cases in which bromazolam was detected in postmortem samples at the University of Alabama at Birmingham (UAB) toxicology laboratory. The decedents ranged in age from 20 to 41 years of age. Most of the decedents were White (n = 8; 80%) and male (n = 7; 70%). Bromazolam concentrations ranged from 21 to 3,220 ng/mL (mean 401 ng/mL). All but one case were polydrug and all deaths were related to drug toxicity. Fentanyl was detected in 8 of the 10 decedents, with concentrations ranging from <2.5 to 97 ng/mL (mean 30 ng/mL). Additional drugs detected were methamphetamine, ethanol, oxycodone, methadone, cocaine, amphetamine, morphine, and diphenhydramine. While all manners of death were ruled as accidental, bromazolam was included in the cause of death statements in nine of the ten cases. Capturing important emerging drug trends on the death certificate is critical to help inform public health and medical colleagues for preventive measures and treatment in the continued drug epidemic.

BeGraft Aortic Stents: A European Multi-Centre Experience Reporting Acute Safety and Efficacy Outcomes for the Treatment of Vessel Stenosis in Congenital Heart Diseases.

BACKGROUND: Stent implantation has become the preferred method of treatment for treating vessel stenosis in congenital heart diseases. The availability of covered stents may decrease complications and have an important role in the management of patients with complex anatomy. AIM: This study aims to evaluate the feasibility and safety of the pre-mounted cobalt-chromium stent-graft-covered ePTFE Aortic BeGraft in a broad spectrum of vascular lesions. METHODS: This is a multicenter retrospective results analysis of 107 implanted BeGraft stents between 2016 and 2022 in six different European centers. RESULTS: One hundred and four patients with a mean age of thirteen years (range 1-70 years) and with the body weight of 56.5 kg (range 11-115 kg) underwent the BeGraft stent implantation. Stents were implanted in the following conditions: aortic coarctation (74 patients), RVOT dysfunction (12 patients), Fontan circulation (7 patients), and miscellaneous (11 subjects with complex CHD). All the stents were implanted successfully. The median stent diameter was 16 mm (range 7-24 mm), and the median length was 39 mm (range 19-49 mm). Major complications occurred in five subjects (4.7%). During a median follow-up of fourteen (1-70) months, stents' re-dilatation was performed in five patients. CONCLUSIONS: The BeGraft stent can be used safely and effectively in a wide spectrum of congenital heart diseases. Whether these good results will be stable in the longer term still needs to be investigated in a follow-up given its recent introduction into clinical practice, in particular regarding stent fracture or neointimal proliferation.

Bicuspid Aortic Valve Disease With Early Onset Complications: Characteristics And Aortic Outcomes.

Bicuspid aortic valve (BAV) is the most common congenital heart malformation in adults but can also cause childhood-onset complications. In multicenter study, we found that adults who experience significant complications of BAV disease before age 30 are distinguished from the majority of BAV cases that manifest after age 50 by a relatively severe clinical course, with higher rates of surgical interventions, more frequent second interventions, and a greater burden of congenital heart malformations. These observations highlight the need for prompt recognition, regular lifelong surveillance, and targeted interventions to address the significant health burdens of patients with early onset BAV complications.

Mind the gap-missing device on the shelf? Retrospective experience with 5/7 Occlutech duct Occluder.

AIM: To describe our initial experience with the indications and results of the 5/7 Occlutech® duct Occluder (ODO, Occlutech International AB, Helsingborg, Sweden). A small incremental increase in occluder sizes is of utmost importance for successful outcomes, especially in smaller patients in whom protrusion of the distal disk towards the aorta should be minimised. METHODS: Retrospective study of all patients undergoing PDA closure with the 5/7 ODO in three institutions since 2018. RESULTS: The 5/7 ODO was used in 18 patients with median age and weight at the time of the procedure of 17.5 months (interquartile range 25th to 75th percentile 8 months- 4.4 years) and 13.6 kg (interquartile range 25th to 75th percentile 6.4-22.5 kg) respectively. All cases were successful. There were no cases of device embolisation, haemolysis, or flow disturbance of the LPA or the aorta. CONCLUSIONS: This small retrospective study demonstrated an excellent outcome of transcatheter PDA closure with the 5/7 ODO. The device is a beneficial complement to the existing sizes of PDA devices, filling the gap between the 4/6 and 6/8 ODO and avoiding protrusion of a larger disk in the aortic isthmus.

Implantation of atrial flow regulator devices in patients with congenital heart disease and children with severe pulmonary hypertension or cardiomyopathy-an international multicenter case series.

Background: The Occlutech Atrial Flow Regulator (AFR) is a self-expandable double-disc nitinol device with a central fenestration. Its use has been approved in the adult population with heart failure and described for pulmonary hypertension (PH). Only case reports and small series have been published about its use in the paediatric population and for congenital heart disease (CHD). Objectives: The authors sought to investigate the feasibility, safety, and short-term follow-up of AFR implantation in patients with CHD or children with PH or cardiomyopathy. Methods: This is a multicenter retrospective study involving 10 centers worldwide. Patients of any age with CHD or patients aged < 18 years with PH or cardiomyopathy needing AFR implantation were included. Results: A total of 40 patients underwent AFR implantation. The median age of the population at the time of the procedure was 58.5 months (IQR: 31.5-142.5) and the median weight was 17 kg (IQR: 10-46). A total of 26 (65.0%) patients had CHD, nine (22.5%) children, a cardiomyopathy, and five (12.5%), a structurally normal heart. The implantation success rate was 100%. There were two early and one late device thrombosis. Two patients (5.0%) with dilated cardiomyopathy on extracorporeal membrane oxygenator (ECMO) died during the hospital stay. At a median follow-up of 330 days (IQR: 125-593), 37 (92.5%) patients were alive. At follow-up, 20 patients improved their New York Heart Association (NYHA) class, 12 patients did not change their NYHA class, and one patient with idiopathic PH worsened. Conclusions: AFR implantation in patients with CHD and children with severe PH or cardiomyopathy is promising and seems to have beneficial effects at short-term follow-up.
