A comparative study of depressive and anxiety symptoms, insomnia, and sleepiness in patients with obstructive sleep apnea, restless legs syndrome, or both (CO-ROSA): preliminary findings from a retrospective study.

Patients with obstructive sleep apnea (OSA), restless legs syndrome (RLS), or both may exhibit varied manifestations of depressive and anxiety symptomatology, reflecting the complex interplay between sleep disturbances, neurotransmitter imbalances, and psychosocial stressors in these often overlapping conditions. The aim of this study was to compare depressive and anxiety symptomatology, insomnia severity, and sleepiness in these conditions. Patients were enrolled and subdivided into those with OSA, RLS, and OSA + RLS.

Material Recovery Facilities (MRFs) in the United States: Operations, revenue, and the impact of scale.

An analysis was conducted using nationwide survey data to evaluate how material recovery facilities (MRFs) operations vary regionally and with scale. The survey characterized materials, processes, and energy use involved with operations, and revenue for recyclables. This is the first nationwide analysis of MRFs in the US that accounts for mass processed, energy consumed, and revenue.

The change process questionnaire (CPQ): A psychometric validation.

Tracking therapeutic processes and outcomes session to session, known as feedback-informed treatment (FIT), has shown many significant benefits for systemic family therapists. However, more clinically useful FIT measures are needed in our field. In response, we conceptualize core dimensions of the therapeutic change process and propose a measure-the Change Process Questionnaire (CPQ)-based on some of those dimensions to provide a clinically useful FIT measure.

Forming our grief rhythm: The relational window of tolerance for bereaved parents.

The shared loss of a child can present challenges to couple relationships as both partners attempt to cope with their own grief and their partner's grief. In this longitudinal qualitative study, five bereaved parent couples participated in 13 total interviews, revealing coregulatory interactions surrounding their shared loss. Using thematic coding and grounded theory analysis, their reflections were organized into three interrelated process themes: regulating self, regulating other, and forming our grief rhythm.

Modalities for teaching responsible and ethical conduct of research online: Lessons learned from an undergraduate workshop in Utah.

The COVID-19 pandemic disrupted scientific research, teaching, and learning in higher education and forced many institutions to explore new modalities in response to the abrupt shift to remote learning. Accordingly, many colleges and universities struggled to provide the training, technology, and best practices to support faculty and students, especially those at historically disadvantaged and underrepresented institutions. In this study we investigate different remote learning modalities to improve and enhance research education training for faculty and students.

An investigation of social media labeling decisions preceding the 2020 U.S. election.

Methods: Eligible patients were post-operatively randomly assigned to one of two parallel groups in a 1:1 ratio, to have their RT delivered using either a 3DRT technique or using IMRT. The prescription dose was 45 Gy in 25 fractions over 5 weeks followed by vaginal vault brachytherapy.

Perforating Gout: Expanding the Differential for Transepidermal Elimination.

Perforating dermatoses are dermatologic disorders with transepidermal elimination (TE) of dermal substances. While TE is typically associated with collagen and elastin, it can also occur as a secondary event in other processes, and it is important to keep a broad differential. We present a case of perforating tophaceous gout, which underscores the need for a thoughtful approach to perforating disorders.

This study focused on validating the data from the initial study, as well as cross examining the need to include admission diagnosis within the tool.

Method: Study was a single-centered, retrospective chart review study using a different subset of patients from the initial study.

Techno-Economic and life cycle assessment of standalone Single-Stream material recovery facilities in the United states.

Material Recovery Facilities (MRFs) are crucial players in achieving a circular economy. MRFs receive complex waste streams and separate valuable recyclables from these mixtures. This study conducts techno-economic analysis (TEA) to estimate the net present value (NPV) and life cycle assessment (LCA) to estimate different environmental impacts of a commercial scale standalone, single-stream MRF to assess the economic feasibility and environmental impacts of recovering valuable recyclables from an MRF processing 120,000 tonnes per year (t/y).

The effect of light emission spectrum on biohydrogen production by Rhodopseudomonas palustris.

Photofermentative hydrogen production has gained increasing attention as a source of green energy. To make such photofermentation processes economically competitive, operating costs need to be reduced, possibly through outdoor operation. Because photofermentation processes are light dependent, the emission spectrum and intensity of light both have a significant influence on the hydrogen production and merit investigation.

The effect of diurnal light cycles on biohydrogen production in a thermosiphon photobioreactor.

Hydrogen production via microbial photofermentation shows great promise as a method for sustainable hydrogen production; however, operating costs associated with photofermentative hydrogen production need to be reduced. Costs can be reduced using a passive circulation system like the thermosiphon photobioreactor, and by operating it under natural sunlight. In this study, an automated system was implemented to investigate the effect of diurnal light cycles on the hydrogen productivity and growth of Rhodopseudomonas palustris and on the operation of a thermosiphon photobioreactor, under controlled conditions.

Barriers and facilitators to guideline-recommended care of benign paroxysmal positional vertigo in the ED: a qualitative study using the theoretical domains framework.

Background: Benign paroxysmal positional vertigo (BPPV) is a common presentation to the ED. Evidence suggests low adherence to guideline-recommended care, but the reasons underlying this are poorly understood. This study used the theoretical domains framework (TDF) to explore the barriers and facilitators to medical and physiotherapy clinical practices in the management of BPPV in an Australian metropolitan ED.

Modelling and testing of a light reflector system for the enhancement of biohydrogen production in a thermosiphon photobioreactor.

One of the main factors affecting hydrogen production and growth of photofermentative microorganisms is light; low light penetration and utilization are significant bottlenecks in photofermentative hydrogen production systems. In this study, light distribution in a thermosiphon photobioreactor operated with Rhodopseudomonas palustris was investigated. Radiation fields were modelled and simulated using computational fluid dynamics (ANSYS® Fluent, 2019 R2) and a reflector system was evaluated for the enhancement of light distribution in a thermosiphon photobioreactor.

Meiotic drive adaptive testes enlargement during early development in the stalk-eyed fly.

The sex ratio (SR) X-linked meiotic drive system in stalk-eyed flies destroys Y-bearing sperm. Unlike other SR systems, drive males do not suffer fertility loss. They have greatly enlarged testes which compensate for gamete killing.

The burden and impact of recurrent abdominal pain - exploring the understanding and perception of children and their parents.

Synchronous visceral Kaposi sarcoma and extracavitary primary effusion lymphoma in a patient with AIDS.

While infection should always lead the differential when a patient with AIDS presents with fever, inflammatory and malignant aetiologies should also be considered. With profound immunocompromise, malignancies can develop as sequelae of viral oncogene expression. Human herpesvirus 8 (HHV-8) infection drives several AIDS-related cancers including Kaposi sarcoma (KS), multicentric Castleman disease and primary effusion lymphoma (PEL), which can present simultaneously with variable clinical features.

Hagfish to Illuminate the Developmental and Evolutionary Origins of the Vertebrate Retina.

The vertebrate eye is a vital sensory organ that has long fascinated scientists, but the details of how this organ evolved are still unclear. The vertebrate eye is distinct from the simple photoreceptive organs of other non-vertebrate chordates and there are no clear transitional forms of the eye in the fossil record. To investigate the evolution of the eye we can examine the eyes of the most ancient extant vertebrates, the hagfish and lamprey.

Popliteal artery entrapment syndrome.

Popliteal artery entrapment syndrome (PAES) is an uncommon cause of lower extremity exertional claudication due to external compression of vascular structures in the popliteal fossa. A developmental anomaly due to an aberrant relationship of the artery with the surrounding myofascial structures contributes to the vascular compromise. PAES presents in younger, athletic patients without atherosclerotic risk factors.
