Firefighters' medical use and Korean Medicine experience in Korea: A qualitative study protocol.

INTRODUCTION: Firefighters, compared to other occupational groups, are exposed more frequently in their working environment not only to physical issues, such as musculoskeletal disease, respiratory disease, and burns but also to mental health issues, such as PTSD and depression. Specifically, Korean firefighters experience significantly higher rates of work-related injuries compared to those in other countries. Recent statistics from the Korea National Fire Agency indicate a steady increase in the number of firefighting work-related injuries. However, there is a shortage of measures in place to address these issues. This study aims to investigate the health needs, overall healthcare usage, and unmet needs of firefighters in Korea. We also aim to investigate, through in-depth interviews, perceptions and hindering factors for integrative medicine approaches to fulfilling unmet needs. METHOD: This study was conducted in accordance with the consolidated criteria for reporting qualitative research. Convenience and snowball sampling methods will be used to recruit firefighters to participate in the study, and interviews will be conducted using a semi-structured interview guide. The data will be analyzed in four stages using the qualitative analysis method of Krippendorff. DISCUSSION: In this study, we examine the state of health issues and healthcare usage among Korean firefighters and investigate their perceptions of and needs for integrative medicine. In this way, we aim to explore how integrative medicine and Korean medicine approaches could improve and assist healthcare services for firefighters. Furthermore, our findings will provide policymakers and healthcare providers with the necessary basic information to develop integrative medicine systems suited to firefighters.

Gochujang Consumption Prevents Metabolic Syndrome in a High-Fat Diet Induced Obese Mouse Model.

High-fat and high-salt diets are risk factors for metabolic syndrome development. However, gochujang, which has a high salt content, possesses antiobesity properties in cell and animal models. We aimed to evaluate the effects of Sunchang traditional and modern factory produced gochujang on metabolic syndrome factors in high-fat diet (HFD)-induced obese mice. For 14 weeks, 4-week-old C57BL/6J male mice were separated into five groups and fed a normal diet (ND), a high-fat diet only (HD), a HD with salt (SALT), a HD with traditional Sunchang gochujang (TS), and HD with modern factory made Sunchang gochujang (FS). Compared to HD and SALT groups, the gochujang groups had lower body weight, blood leptin, and insulin levels with reduced Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) index and improved serum and liver lipid profiles. In addition, gochujang supplemented groups exhibited a significant reduction in mRNA expression of anabolic lipid metabolism related factors; PPARγ, CEBPα, and FABP4, and a significant increase in mRNA expression of energy expenditure-related factors; PPARα and CPT1. Protein expressions of SREBP1 were downregulated in the gochujang fed groups. TS and FS intakes improved obesity in HFD-induced obese mice. Compared to the gochujang groups, the SALT group did not exhibit any of those benefits suggesting that the high salt content of gochujang has different effects compared with added salt alone. Our findings provide evidence that gochujang could be a functional food to attenuate metabolic syndrome.

Understanding the experiences and perception of people living with HIV on integrative traditional East Asian medicine management in Korea: an interview protocol for qualitative research.

INTRODUCTION: Patients with HIV/AIDS have been able to experience the average life expectancy of the general population due to medical advancements. However, they face physical, emotional and social difficulties that worsen their quality of life. The pharmacological approach is often the first choice to address these issues, but it involves some limitations. Integrative traditional East Asian medicine (ITEAM) can compensate for the limitations of drugs and can be applied to treat physiological and psychiatric problems. In Korea, ITEAM interventions are easily accessible under the government insurance. However, the experiences, perceptions and barriers to the use of ITEAM in patients with HIV/AIDS are less studied. Therefore, we will interview them to explore their experiences and examine the strengths, limitations, barriers and improvements in the use of ITEAM. METHODS AND ANALYSIS: This is a qualitative study using a phenomenological framework. We will conduct one-to-one interviews with 3-10 patients with HIV/AIDS who have been treated with ITEAM from March 2021 to January 2022. We will present semistructured open-ended questions and analyse them using experiential phenomenological research methods. The results will be reported in accordance with the Consolidated Criteria for Reporting Qualitative Studies. ETHICS AND DISSEMINATION: This research was approved by the Institutional Review Board of the National Medical Center (IRB number, NMC-2101-008). The results of this study will be disseminated through journal articles, newspapers and conference proceedings.

Calcium-alginate beads as a formulation for the application of entomopathogenic nematodes to control rootworms.

Entomopathogenic nematodes (EPN) have great potential as biological control agents against root-feeding insects. They have a rapid and long-lasting mode of action, minimal adverse effects on the environment and can be readily mass-produced. However, they have a relatively short shelf-life and are susceptible to desiccation and UV light. These shortcomings may be overcome by encapsulating EPN in Ca2+-alginate hydrogels, which have been shown to provide a humid and UV protective shelter. Yet, current Ca2+-alginate formulations do not keep EPN vigorous and infectious for a prolonged period of time and do not allow for their controlled release upon application. Here, we introduce solid Ca2+-alginate beads which we supplemented with glycerol to better retain the EPN during storage and to ensure a steady release when applied in soil. Glycerol-induced metabolic arrest in EPN (Heterorhabditis bacteriophora) resulting in quiescence and total retainment of EPN when added to beads made with 0.5% sodium alginate and 2% CaCl2·2H2O solutions. More than 4,000 EPN could be embedded in a single 4-5-mm diameter bead, and quiescence could be broken by adding water, after which the EPN readily emerged from the beads. In a field trial, the EPN beads were as effective in reducing root damage by the western corn rootworm (WCR, Diabrotica virgifera virgifera) as EPN that were applied in water. Although further improvements are desirable, we conclude that Ca2+-alginate beads can provide an effective and practical way to apply EPN for the control of WCR larvae.

Pathways From Peer Victimization to Sexually Transmitted Infections Among African American Adolescents.

African American youths, especially those in low resource communities, are vulnerable to peer victimization, which can increase risk of sexually transmitted infections. However, few studies explored the relationship between these two health concerns and the pathways that may link them. The present study aimed to address this gap. We used descriptive statistics, correlation coefficients, and structural equation modeling to analyze data collected from 277 adolescents ages 13 to 24 years in Chicago. Primary results indicated that peer victimization was not directly related to acquisition of sexually transmitted infections. However, peer victimization was negatively associated with condom use, and condom use was negatively associated with sexually transmitted infections. Furthermore, affiliation with sexually active peers was positively associated with substance use. These findings have implications for bullying and sexual risk prevention and intervention of low-income youths. Attention to treatment approaches and interventions that are holistic and culturally feasible is recommended for practitioners working with urban youth.
