Department of Cardiovascular Surgery, Osaka General Medical Center, Osaka, 558-8558, Japan.
Background: Left atrial dissection is a rare and occasionally fatal complication of cardiac surgery and is defined as the creation of a false chamber through a tear in the mitral valve annulus extending into the left atrial wall. Some patients are asymptomatic, while others present with various symptoms, such as chest pain, dyspnea, and even cardiac arrest. Although there is no established management for left atrial dissection, surgery should be considered in patients with hemodynamic disruption.

Background: People in justice settings experience higher rates of psychiatric morbidity, including alcohol and drug use disorders, compared with the general population. However, our understanding of opioid-related harms in justice settings is limited. This study used ambulance data to examine opioid-related harms and experiences of care in New South Wales (NSW), Australia, during periods of incarceration or detention.

Situations when field researchers are tempted to deviate from preselected sampling plan and to include nearby or related units in sample, then adaptive cluster sampling (ACS) offers a nearly completion solution. For rare and clustered populations, Thompson introduced ACS as an effective sampling method when data is not contaminated with outliers. However, traditional approaches produce distorted results when data includes outliers.

Department of Systems Design Engineering, University of Waterloo, Waterloo, ON, N2L 3G1, Canada.
This paper presents a novel technique for low-power generation of frequency combs (FC) over a wide frequency range. It leverages modal interactions between electrical and mechanical resonators in electrostatic NEMS operating in air to provide a simple architecture for FC generators. A biased voltage signal drives the electrical resonator at resonance which is set to match an integer submultiple of twice the mechanical resonator's resonance.

Dermatology Service, Universidade do Estado do Pará, Belém, PA, Brazil.
Background: Cutaneous tuberculosis is a rare form of the disease that defies diagnosis due to the diversity of clinical presentations. This study was based on the reality of a dermatology referral center in the Brazilian Amazon region to detail several characteristics of this disease.
Objective: To describe a series of cases of cutaneous tuberculosis treated at a dermatology service in the Brazilian Amazon region, addressing epidemiological aspects, clinical forms, diagnostic methods, treatment, and outcomes.
