Comment on "Breakdown of electroneutrality in nanopores".

Levy et al. [1] reported the breakdown of electroneutrality in confined nanopores embedded in a dielectric medium. A Robin boundary condition was derived which eliminates the need to include the dielectric medium explicitly when solving for the electric field within the nanopore.

Constructing a Nurse-led Cardiovascular Disease Intervention in Rural Ghana: A Qualitative Analysis.

Background: Cardiovascular disease (CVD) is a growing burden in low- and middle-income countries. Ghana seeks to address this problem by task-shifting CVD diagnosis and management to nurses. The Community-Based Health Planning and Services (CHPS) initiative offers maternal and pediatric health care throughout Ghana but faces barriers to providing CVD care.

A Medical Student Postpartum Telehealth Initiative During the COVID-19 Pandemic.

Purpose: The coronavirus disease 2019 (COVID-19) pandemic has had an unprecedented impact on our health systems and delivery of care and on the disruption of medical education. It has forced hospitals to move to a telehealth model for prenatal and postpartum visits and expedite discharges for postpartum patients in order to reduce exposure. We describe our medical school and hospital system initiative to employ medical student volunteers for postpartum telehealth calls during the peak of the COVID-19 pandemic in New York City.

The Bolivian trauma patient's experience: A qualitative needs assessment.

Background: Despite a significant burden of injury-related deaths, the Plurinational State of Bolivia (Bolivia), a lower- middle-income country in South America, lacks a formalized trauma system. This study sought to examine Bolivian trauma care from the patient perspective in order to determine barriers to care and targets for improvement.

Methods: Investigators conducted 15 semi-structured interviews with trauma patients admitted at four hospitals in Santa Cruz de la Sierra, Bolivia in June and July of 2016.

Anticoagulation Management for Impella Percutaneous Ventricular Assist Devices: An Analysis of a Single-Center Experience.

Background: Impella devices offer temporary mechanical circulatory support for cardiogenic shock. The manufacturer recommends systemic anticoagulation with a target activated clotting time of 160 to 180 s but provides no guidance on how to manage both the heparinized purge solution and the additional intravenous heparin needed to reach this therapeutic range. Previous publications demonstrated a lack of standardization in heparin management for Impella devices.

What is trauma? Qualitatively assessing stakeholder perceptions in Santa Cruz de la Sierra, Bolivia.

Addressing the burden of injury in low-resource settings requires development of trauma systems. This study aimed to describe perceptions of trauma in Santa Cruz, Bolivia to better inform strategies for trauma system development. In 2015-2016, we conducted 16 individual and 11 group interviews with key stakeholders involved with or exposed to trauma.

Spontaneous recanalization of a total occlusion of an infrarenal abdominal aorta after left axillary-bifemoral bypass.

Acute aortic occlusion is an infrequent clinical event with high morbidity and mortality. Management is determined by the cause of the occlusion, with thromboembolectomy used for embolic events and bypass for thrombotic events. After bypass, recanalization of a total aortic occlusion has been sparsely reported.
