Martial arts and combat sports (MACS) are supported on ritualistic practices which often encompass hazing creating environments where catastrophic masculinities prevail. These forms of masculinities are strengthened inside MACS’ world resonating with masculinities spread out in wider society. We consider this to be the situation found in Brazilian society. With this study, our aim is to analyse how hazing practices in MACS contribute to the production of a socially legitimised catastrophic masculinity in Brazil. Catastrophic masculinity appears as a new concept proposed by Andrade (2022) to define a hegemonic, toxic and tragic form of masculinity spread in Brazil attached to a political power project. We carried out two qualitative empirical pieces of research that focused on three martial arts. These were ethnographic (participant-) observations of various events, training sessions, belt examination and competition and interviews with men participants. Supported by the presented data, we argue that hazing practices end up acting as a means of reproducing the catastrophic masculinity fighters perform in the dojo. They learn and resonate with a pedagogy that requires them to conform to and follow hierarchies through the repetition of the word ‘oss’ as a symbol of submission to arbitrariness. Hazing constitutes, instantiates and reproduces catastrophic masculinity and originates in the same (social) catastrophic masculinity.

Protein-energy wasting is a common complication among patients with kidney failure undergoing dialysis. This study aims to develop a homemade oral nutrition supplement (ONS) to fulfill the energy and protein requirements of these patients.

Three formulations of homemade ONS were developed using soybean milk, whey protein isolates and canola oil. Two of these formulations were flavored with pineapple and honeydew juices, respectively. The energy and macronutrient contents were determined using proximate analyses, and mineral contents were determined using inductively coupled plasma optical emission spectroscopy. The acceptance of homemade ONS for five attributes, namely color, taste, odor, consistency and overall acceptability, was assessed using the nine-point hedonic scale.

The homemade ONS provided 198–212 kcal and 8.4–9.6 g protein per 100 mL, which were comparable to commercial products. Similarly, the sodium (45–65 mg/100 mL) and phosphorus (56–66 mg/100 mL) contents were on par with commercial products. However, the potassium content of homemade ONS was higher, ranging from 141 to 155 mg per 100 mL. The sensory evaluation indicated that the formulation added with honeydew juice had a similar degree of acceptance as the commercial ONS, while formulations containing pineapple juice and without added fruit juice were less favored.

A few studies have investigated the development of food products for individuals with kidney failure on dialysis. However, to the best of the authors’ knowledge, this is the first study to focus on developing a homemade ONS specifically tailored to meet the unique nutritional needs of hemodialysis patients. In addition, this research included a comprehensive assessment of the beverage’s nutritional content and sensory attributes.

This practice forum paper aims to present a theoretical framework to better develop the required supply chain management (SCM) competencies and the workforce needed for managing public health supply chains.

This framework is driven by iterative systems thinking, a deeper consideration of the SCM labor market and a comprehensive mapping of human resource system requirements. The framework centers around three tools. A labor market analysis assesses factors influencing supply of and demand for health SCM workers in a country context. To improve supply of and demand for workers, the SCM Professionalisation Framework provides reference documents to establish health SCM as a recognized profession. The human resources for SCM Theory of Change explains and assesses the conditions required to achieve optimal workforce performance at the organizational level. The Ministry of Health in Rwanda applied these three tools sequentially to assess and improve the supply and performance of its health SCM workforce.

The authors describe this framework, how the tools were applied in Rwanda, and early impressions of the results.

Practitioners can apply this approach to improve SCM competence and promote the attractiveness of health SCM positions by formalizing their professional status. This could lead to a pool of individuals who seek SCM qualifications and, in time, overcome the current shortage of health SCM workers. Employers can apply this approach to structured roles and workforce needs to meet health SCM system requirements. This would lead to a greater demand for and use of appropriately trained personnel.

This paper presents a novel, iterative, systems-thinking approach to develop human resources in public health supply chains. Rwanda is the first country to apply all three tools using this framework.
