The endogenous opioid system is commonly targeted in pain treatment, but the fundamental nature of neuropeptide release remains poorly understood due to a lack of methods for direct detection of specific opioid neuropeptides in situ. These peptides are concentrated in, and released from, large dense-core vesicles in chromaffin cells. Although catecholamine release from these neuroendocrine cells is well characterized, the direct quantification of opioid peptide exocytosis events has not previously been achieved.

Since the nature of an electrochemical signal is fundamentally governed by mass transport to the electrode surface, microelectrode geometry can be exploited to achieve precise and accurate measurements. Researchers traditionally pair amperometric measurements of exocytosis with a ∼10-μm diameter, disk microelectrode in an "artificial synapse" configuration to directly monitor individual release events from single cells.

Methods: The health conditions and risk factors of participants identified as sexual and gender minority were compared to those identified as cisgender heterosexual using data from the 2016-2017 National Health Survey.
Results: Despite reporting higher self-rated health than heterosexual men, gay men had a higher risk of lifetime diagnosis of sexually transmitted infections.
Background: A strong nursing research agenda in Latin America is fundamental to universal health coverage. Nursing science can make important contributions to the health of Latin American people through knowledge generation that directly informs nursing practice, professional education, and health policy.
Methods: We used a cross-sectional survey design to assess nursing involvement in health systems and services research in Latin America in five priority areas: Policies and education related to nursing human resources; Structure, organization and dynamics of health systems and services; Science, technology, innovation, and information systems in public health; Health policies, governance, and social control; and Social studies in the health field.
Aims And Objectives: The aims and objectives of this study were to evaluate the oral health status in a group of mentally disabled children, to identify the oral health knowledge of parents and to assess the impact of audiovisual oral health education program.
Materials And Methods: The study sample comprised of 120 mentally disabled subjects aged 5-16 years and 40 parents attending a vocational institute in Jaipur, India. Caries status and oral hygiene status were assessed by DMFT Index and Simplified Oral Hygiene Index (OHI-S) of Greene and Vermillion, respectively.
Background: Nurses are the majority of the world's health work force and the frontline responders during pandemics. The mental/emotional toll can be profound if it is not identified and treated.
Purpose: In March 2020, with New York City as the epicenter of the COVID-19 pandemic in the United States, Columbia University School of Nursing organized support circles for faculty and students providing clinical care as a healing method to address trauma.
Introduction: Analyzing hospital naloxone use may assist in identification of areas for quality and safety improvement. Our primary objective is to quantitate the incidence of hospital naloxone use and to assess certain patient populations at risk.
Methods: During the years 2008 to 2011, each clinical scenario where naloxone was administered on an in-patient care ward was reviewed.
