Background: Quantitative research on non-randomized-samples, focused on statute-mandated-outcomes, has found positive results favoring compulsory-community-treatment (CCT) in jurisdictions fully supporting its implementation. In contrast, three randomized-studies "failed-to-find" a difference between randomly-assigned-CCT and control-groups-each study repeatedly summarized in revisions of a Cochrane-meta-analysis reporting this failure. Considering the potential health and safety threats to people with severe-mental-illness and those with whom they interact, there is a critical need for this investigation to resolve these conflicting results.

Acute injury of skeletal muscle disrupts myofibres, microvessels and motor innervation. Myofibre regeneration is well characterized, however its relationship with the regeneration of microvessels and motor nerves is undefined. Endothelial cell (EC) ephrin-B2 (Efnb2) is required for angiogenesis during embryonic development and promotes neurovascular regeneration in the adult.

Understanding the factors influencing mosquitoes' fecundity and longevity is important for designing better and more sustainable vector control strategies, as these parameters can impact their vectorial capacity. Here, we address how mating affects midgut growth in Aedes aegypti, what role Juvenile Hormone (JH) plays in this process, and how it impacts the mosquito's immune response and microbiota. Our findings reveal that mating and JH induce midgut growth.

Aging increases reactive oxygen species (ROS) which can impair vascular function and contribute to brain injury. However, aging can also promote resilience to acute oxidative stress. Therefore, we tested the hypothesis that advanced age protects smooth muscle cells (SMCs) and endothelial cells (ECs) of posterior cerebral arteries (PCAs; diameter, ∼80 μm) during exposure to HO.

High fat, western-style diets increase vascular oxidative stress. We hypothesized that smooth muscle cells and endothelial cells adapt during the consumption of high fat diets to become more resilient to acute oxidative stress. Male C57Bl/6J mice were fed a western-style diet high in fat and processed carbohydrates (WD), a high fat diet that induces obesity (DIO), or their respective control (CD) and standard (SD) diets for 16 weeks.

Background: Assignment to a community treatment order (CTO) has been associated with reduced mortality risk. In Victoria Australia civil-rights enhancements involving capacity to refuse involuntary treatment have contributed to a 15% reduction between 2010 and 2019 in CTO assignments among first hospitalized patients with Schizophrenia diagnoses. Has this change impacted patient mortality risk?

Study Design: This study considered mortality-risk between 2010 and 2019 for 3 patient groups with schizophrenia diagnoses: All 4848 hospitalized patients who were assigned to a CTO for the first time in the period; 3988 matched and randomly selected patients, who were first hospitalized in the decade, without CTO assignment; and 1675 never hospitalized or CTO-assigned outpatients.

Background: Acute injury to skeletal muscle damages myofibers and fragment capillaries, impairing contractile function and local perfusion. Myofibers and microvessels regenerate from satellite cells and from surviving microvessel fragments, respectively, to restore intact muscle. Established models of injury have used myotoxins and physical trauma to demonstrate the concurrence of myogenesis and angiogenesis during regeneration.

Background: Provision of involuntary care is an abridgment of civil rights and a source of controversy. Its circumstances require continued monitoring. This study asks 4 questions: Whether, in an era, focused on allowing patients with capacity to refuse community-treatment-order (CTO)-assignments, CTO use decreased.

Background: The conclusion that people with severe mental illness require involuntary care to protect their health (including threats due to physical-non-psychiatric-illness) is challenged by findings indicating that they often lack access to general healthcare and the assertion that they would access such care voluntarily if available and effective. Victoria, Australia's single-payer healthcare system provides accessible medical treatment; therefore, it is an excellent context in which to test these challenges.

Aims: This study replicates a previous investigation in considering whether, in Australia's easy-access single-payer healthcare system, patients placed on community treatment orders, specifically involuntary community treatment, are more likely to access acute medical care addressing potentially life-threatening physical illnesses than voluntary patients with and without severe mental illness.

Background: Despite broad interest of the Syrian refugee plight in the academic and media circles, there are still limited studies analyzing the lived experiences of torture survivors under the Syrian regime. This qualitative study interviewed torture survivors to examine the form and function of the Syrian regime's security apparatus, and the personal aftermath of survivors.

Methods: Thirteen in-depth interviews were conducted in Arabic with Syrian refugees who endured torture.

Aim: Brain injury produces reactive oxygen species (ROS). However, little is known of how acute oxidative stress affects cell survival in the cerebral vascular supply. We hypothesized that endothelial cells (ECs) are more resilient to H O and protect vascular smooth muscle cells (SMCs) during acute oxidative stress.

Injury to skeletal muscle disrupts myofibres and their microvascular supply. While the regeneration of myofibres is well described, little is known of how the microcirculation is affected by skeletal muscle injury or its recovery during regeneration. Nevertheless, the microvasculature must also recover to restore skeletal muscle function.

Objective: We sought to define how sensory neurotransmitters substance P and calcitonin gene-related peptide (CGRP) affect membrane potential of vascular smooth muscle and endothelium.

Methods: Microelectrodes recorded membrane potential of smooth muscle from pressurized mouse mesenteric arteries (diameter, ~150 µm) and in endothelial tubes.

Results: Resting potential was similar (~ -45 mV) for each cell layer.

During embryogenesis, blood vessels and nerves develop with similar branching structure in response to shared signaling pathways guiding network growth. With both systems integral to physiological homeostasis, dual targeting of blood vessels and nerves to promote neurovascular regeneration following injury is an emerging therapeutic approach in biomedical engineering. A limitation to this strategy is that the nature of cross talk between emergent vessels and nerves during regeneration in an adult is poorly understood.

Reactive oxygen species (ROS) are implicated in cardiovascular and neurologic disorders including atherosclerosis, heart attack, stroke, and traumatic brain injury. Although oxidative stress can lead to apoptosis of vascular cells, such findings are largely based upon isolated vascular smooth muscle cells (SMCs) and endothelial cells (ECs) studied in culture. Studying intact resistance arteries, we have focused on understanding how SMCs and ECs in the blood vessel wall respond to acute oxidative stress induced by hydrogen peroxide, a ubiquitous, membrane-permeant ROS.

Outpatient civil commitment (OCC) requires people with severe mental illness (SMI) to receive needed-treatment addressing imminent-threats to health and safety. When available, such treatment is required to be provided in the community as a less restrictive alternative (LRA) to psychiatric-hospitalization. Variance in hospital-utilization outcomes following OCC-assignment has been interpreted as OCC-failure.

This research examines Syrian refugee mothers' accounts of the physical and mental health of their children being affected by war traumas and displacement challenges. Open-ended audio-recorded interviews were conducted in Arabic with 23 mothers residing in Jordan. Using a narrative approach in the data collection and analysis, five major themes were identified: (1) children were exposed to diverse war traumatic experiences in Syria; (2) the escape journey and refugee camps threatened children's lives; (3) displacement and family stressors exposed children to poverty, hostility from local peers, educational and recreational challenges, child labor, and domestic violence (these three major themes were considered as trauma related variables); (4) children were not only directly affected physically and mentally by their own traumatic experiences and displacement stressors, but these experiences were mediated and magnified by familial interrelated processes, evidenced in intergenerational transmission of trauma, harsh parenting style, parental control, and parentification; and (5) adverse consequences of both trauma related variables and family processes directly and indirectly traumatized children and adversely impacted their physical and mental health.
