Muscle cells, nerves, fibroblasts and vessels in the detrusor of the rat urinary bladder.
Muscle cells, nerves, fibroblasts and vessels in the detrusor of the rat urinary bladder. J Smooth Muscle Res. 2019;55(0):34-67 Authors: Gabella G Abstract All the cells of rat detrusor muscle fall into one of five ultrastructural types: muscle cells, fibroblasts, axons and glia, and vascular cells (endothelial cells and pericytes). The tissue is ~79% cellular and 21% non-cellular. Muscle cells occupy 72%, nerves ~4% (1/3 axons, 2/3 glia), and fibroblast>3% of space. Muscle cells (up to 6 µm across and ~600 µm long, packed to almost 100,000 per mm2) have surface-to-volume ratio of 2.4 µm2/µm3 ~93% of cell volume is contractile apparatus, 3.1% mitochondria and 2.5% nucleus. Cell profiles are irregular but sectional area decreases regularly towards either end of the cell. Muscle cells are gathered into bundles (the mechanical units of detrusor), variable in length and size, but of constant width. The musculature is highly compact (without fascia or capsule) with smooth outer surfaces and extensive association and adhesion between its cells. Among many types of intercellular contact and junction, digitations are very common, each muscle cell issuing minute finger-like processes that abut on adjacent cells. Sealed apposition are wide areas of specialized contact, possibly forming a chamber between two muscle cells, distinct from the extracellular space at large (stromal space). The innervation is very dense, virtually all intramus...

Publication date: Available online 7 December 2019Source: Case Reports in Women's HealthAuthor(s): Gordon Narayansingh, Jennifer HohAbstractAbdominal pain following in vitro fertilization (IVF) in the presence of enlarged ovaries commonly leads to the diagnosis of ovarian hyperstimulation syndrome (OHSS). Progressively worsening pain with a rise in inflammatory markers with normal hematological indices implies a diagnosis of ovarian torsion of the hyperstimulated ovary. Early recourse to laparoscopic assessment and derotation of the affected ovary even after 72 h following the onset of symptoms can allow a return to viab...

ABSTRACT: Intimate partner violence (IPV) occurs across all cultures, ethnicities, socioeconomic classes, and educational backgrounds. Nurses should be aware of IPV and causative factors that include personal attributes, stressors, and community issues. The Intimate Partner Exposome conceptual model is used to identify exogenous and endogenous IPV risk factors. In addition, distinctive environmental factors can increase risk for IPV. The purpose of this article is to increase recognition of causative factors and presenting signs to enhance the nurse's ability to identify and assist IPV victims.
This article discusses the experience of maternal loss and notes care needs of the motherless child-adult woman. Identification of women in this situation should be made as early as possible.
ABSTRACT: High mortality rates continue among African Americans related to complications of uncontrolled hypertension. The purpose of this study was to determine if a faith-based self-management education program would improve self-care activities related to the management of hypertension among African American adults. Ten African American adults who reported a diagnosis of hypertension for 6 months or longer completed an 8-week education program focused on strategies for hypertension management. The education program was enhanced with the utilization of spiritual components of prayer, Scripture reading, and journaling.
ABSTRACT: There has been an increase in student enrollment in advanced practice nurse programs, but limited information regarding attrition and dropout rates in nurse practitioner (NP) programs. Management of NP students includes student evaluations, preceptor guidance and support, student support, and use of reflective practice. Program directors, faculty members, and preceptors must assist NP students with role transitioning and help those who are not meeting the rigors of NP education to leave the program and discover alternative nursing roles.
