Exploring the Unidimensionality of the GAD-7 for South African First Responders: Evidence from Multiple Psychometric Approaches

Received: 21 September 2024;  Published: 27 January 2025;  doi: 10.21926/obm.neurobiol.2501266

Abstract

Generalized Anxiety Disorder (GAD) is a prevalent mental health condition and the GAD-7 is widely used as a screening tool and measure of GAD severity. However, research has yielded conflicting findings regarding the factor structure of the instrument, with some studies supporting a unidimensional interpretation while others suggest a two-factor solution. These inconsistencies highlight the importance of validating the GAD-7 across diverse populations. This study aimed to assess the psychometric properties and fact [...]

Maternally Derived Complex Small Supernumerary Marker Chromosome 22 Associated with Cat-Eye Syndrome Like Features

Received: 14 October 2024;  Published: 27 January 2025;  doi: 10.21926/obm.genet.2501282

Abstract

Cat-eye syndrome (CES) is a rare genetic disease first reported in 1965. The estimated prevalence of CES is 1:50,000 to 1:150,000, and it is typically associated with an inverted duplicated small supernumerary marker chromosome (sSMC) derived from chromosome 22. The specific chromosomal band involved in CES causing partial tetrasomy is 22q11.21, where chromosomal rearrangements occur due to the presence of low-copy repeats (LCR22). The phenotype of CES is extremely diverse, ranging from normal to multiple abnormali [...]

A Narrative Review of the Evidence Supporting Nutritional Supplementation for Better Muscle Health in Older Adults

Received: 15 February 2024;  Published: 23 January 2025;  doi: 10.21926/obm.geriatr.2501296

Abstract

Sarcopenia is characterised by progressive and generalised decline in muscle strength, function, and muscle mass. Now recognised as a muscle disease, it is highly prevalent in older adults, with estimates of up to 30% in some populations. Sarcopenia has a complex multifactorial aetiology, including cellular and molecular changes, chronic disease, lower physical activity as well as nutritional deficiency. Sarcopenia is associated with a range of adverse physical and metabolic outcomes leading to disability, morbidit [...]

Versatility of the Axillary Intra-Aortic Balloon Pump in Adult Cardiac Surgery

Received: 23 July 2024;  Published: 22 January 2025;  doi: 10.21926/obm.transplant.2501232

Abstract

The axillary intra-aortic balloon pump (ax-IABP) has been proposed as an alternative to the femoral IABP, particularly for patients with comorbidities rendering them unsuitable for fem-IABP insertion. Patient mobilisation with the ax-IABP in situ is deemed an additional potential benefit. We reviewed our experience with the ax-IABP. A single-centre retrospective review of all adult patients undergoing cardiac surgery (including heart transplantation) in a UK quaternary cardiac surgery centre between 2017 and 2021 w [...]

Advancements in Silkworm-Derived Silk Fibroin Biomaterials for Peripheral Nerve Regeneration

Received: 14 October 2022;  Published: 20 January 2025;  doi: 10.21926/obm.neurobiol.2501265

Abstract

Regenerating injured nerves is difficult because they have little spontaneous regeneration potential. Advances in tissue engineering and regenerative medicine have emphasized the possibility of biomaterial-based methods for nerve healing. Natural protein-based biomaterials have benefits over synthetic ones, such as biocompatibility, non-immunogenicity, and biodegradability. Silk fibroin, generated from mulberry and non-mulberry silkworms, is especially promising because of its abundance, simplicity of processing in [...]

Time is a Precious Commodity: Reframing Farmer Stress and Mental Health Through the Lens of Time Poverty

Received: 24 September 2024;  Published: 16 January 2025;  doi: 10.21926/obm.icm.2501005

Abstract

In this conceptual paper we apply the construct of time poverty to a novel population, farmers struggling with stress and mental health challenges. Farmers have rates of suicide that can be over three times that of the general population, with depression and anxiety at double general population rates. These are linked to the multiple stressors farmers experience due to the unpredictable nature of their work, such as weather, input costs, commodity prices, and government regulations. In addition, there are multiple [...]

Comparison Between How Narrative Therapy and Buddhist Mantra-Based Meditation Promote Mental Healing

Received: 15 June 2024;  Published: 15 January 2025;  doi: 10.21926/obm.icm.2501004

Abstract

This is a conceptual paper comparing how narrative therapy and Buddhist mantra-based meditation promote mental healing. Narrative therapy promotes mental healing by shifting families’ attention to their subjugated stories of strengths and personal agencies. Whilst Buddhist meditation has been integrated into psychotherapy developed in the West, the application is primarily the focus on breath as a way to help sufferers attain mindfulness. Mantra-based meditation uses the recitation of mantra as the focus inst [...]

On the Relation between Overwater Friction Velocity and the Wind Speed During Tropical Cyclones

Received: 17 October 2024;  Published: 15 January 2025;  doi: 10.21926/aeer.2501007

Abstract

In the realm of marine meteorology, physical oceanography, and coastal and ocean engineering, the wind-stress across the air-sea interface plays a dominant role. However, under tropical cyclone conditions, there is no consensus for the formulation of the drag coefficient, Cd, in the literature. Based on the wind-gust method and the measurements from data buoy 42001 during Hurricane Lili, it is demonstrated that, U* = 0.073U10 - 0.44, which is valid up to wind speed 47 m s-1 and wind gust to 66 m s-1, here U* is the [...]
