Purpose: This study aimed to understand the experiences of dialysis and their meaning among patients with chronic kidney disease through a meta-synthesis of the existing literature. Since 2010, the prevalence of end-stage renal disease has doubled in South Korea, which has the sixth-highest incidence worldwide. Although most kidney disease patients undergo dialysis to attenuate disease-related symptoms and prolong their lives, the implications of dialysis on their lives, together with the role played by patients’ significant others, remain underexplored. Similarly, existing research has not considered both patients with hemodialysis and peritoneal dialysis. Methods: In this meta-synthesis, seven electronic databases (PubMed, CINAHL, EMBASE, PsycINFO, DBpia, KISS, and RISS) were searched for the terms “dialysis” and “qualitative.” Thirty qualitative studies were selected for examination. Results: The overriding theme observed in the studies was “I do not have much time left.”–navigating the dual realities of one’s limited existence, while other key themes were: (1) the inevitable experience of the troubles of dialysis, (2) life is extended, but deteriorating in every aspect, (3) accepting dialysis with a positive outlook for life, and (4) essential support experienced in an exhausting life. Conclusion These findings are important for the design and delivery of practical and tailored nursing interventions to help patients overcome the various challenges related to dialysis treatment, and improve their quality of life.

Purpose: This study investigates the medical application of X-rays and radium in treating female patients in 1930s Korea. Methods This research analyzes 1930s newspapers, medical journals, and women’s magazines to explore public perceptions of the healing and harmful effects of therapeutic radiation. Results: This study found that women’s bodies served as key sites for introducing new medical knowledge and technologies. Identified primarily as patients, housewives, and consumers, women contributed to normalizing radiation use in public and domestic settings, despite the lack of established safety standards. The transnational flow of medical devices, expertise, and personnel also highlighted both shared and distinct experiences of radiation therapy across national and imperial boundaries. Conclusion: While no direct causality links those varied experiences, comparing cases such as a Korean woman skeptical of radiation for breast cancer, a Japanese housewife who sued over radiation burns, and an American nurse whose expertise with X-rays conflicted with her caregiving role, offer insights into the meaning of modern medicine in colonial Korea.

Background/Aims: This study aimed to identify the clinical characteristics of patients with concurrent rheumatoid arthritis (RA) and suspected non-tuberculous mycobacterial (NTM) infections as well as determine their prognostic factors. Methods: We retrospectively reviewed the medical records of 91 patients with RA whose computed tomography (CT) findings suggested NTM infection. Subsequently, we compared the clinical characteristics between patients with and without clinical or radiological exacerbation of NTM-pulmonary disease (PD) and investigated the risk factors for the exacerbation and associated mortality. Results: The mean age of patients with RA and suspected NTM-PD was 65.0 ± 10.2 years. The nodular/bronchiectatic (NB) form of NTM-PD was the predominant radiographic feature (78.0%). During follow-up, 36 patients (41.9%) experienced a radiological or clinical exacerbation of NTM-PD, whereas 12 patients (13.2%) died. Combined interstitial lung disease (ILD), microbiologically confirmed NTM-PD, and NB with the fibrocavitary (FC) form on chest CT were identified as risk factors for the clinical or radiological exacerbation of NTM-PD. Hydroxychloroquine use was identified as a good prognostic factor. Conversely, history of tuberculosis, ILD, smoking, microbiologically confirmed NTM-PD, and NB with the FC form on chest CT were identified as poor prognostic factors for mortality in suspected NTM-PD. Conclusions ILD and NB with the FC form on chest CT were associated with NTM-PD exacerbation and mortality. Hydroxychloroquine use may lower the risk of NTM-PD exacerbation. Therefore, radiographic features and presence of ILD should be considered when predicting the prognosis of patients with RA and suspected NTM-PD.

Immunologists have activated T cells in vitro using various stimulation methods, including phorbol myristate acetate (PMA)/ionomycin and αCD3/αCD28 agonistic antibodies. PMA stimulates protein kinase C, activating nuclear factor-κB, and ionomycin increases intracellular calcium levels, resulting in activation of nuclear factor of activated T cell. In contrast, αCD3/αCD28 agonistic antibodies activate T cells through ZAP-70, which phosphorylates linker for activation of T cell and SH2-domain-containing leukocyte protein of 76 kD. However, despite the use of these two different in vitro T cell activation methods for decades, the differential effects of chemical-based and antibody-based activation of primary human T cells have not yet been comprehensively described. Using single-cell RNA sequencing (scRNA-seq) technologies to analyze gene expression unbiasedly at the single-cell level, we compared the transcriptomic profiles of the non-physiological and physiological activation methods on human peripheral blood mononuclear cell–derived T cells from four independent donors. Remarkable transcriptomic differences in the expression of cytokines and their respective receptors were identified. We also identified activated CD4 T cell subsets (CD55+) enriched specifically by PMA/ionomycin activation. We believe this activated human T cell transcriptome atlas derived from two different activation methods will enhance our understanding, highlight the optimal use of these two in vitro T cell activation assays, and be applied as a reference standard when analyzing activated specific disease-originated T cells through scRNA-seq.

Purpose: This study aimed to analyze the immunologic profile of children with postinfectious bronchiolitis obliterans (PIBO) in order to approach pathophysiology affected by host factors. Methods: A total of 10 children with PIBO were prospectively enrolled. We obtained information on demographics from their caregiver and electric medical records. Peripheral blood samples were collected before cyclic systemic methylprednisolone therapy and complete blood count, immunoglobulin level and lymphocyte subset were analyzed. Results: The white blood cell count and immunoglobulin level were within the normal range in children with PIBO. The CD4+/CD8+ ratio was not significantly different from those of the healthy control group. A decreased proportion of both central memory T cells (median [interquartile range]; 13.5% [8.3%–16.3%] vs. 18.5% [15.9%–24.1%], P = 0.01) and effector memory T cells (10.3% [5.0%–18.4%] vs. 20.9% [16.6%–26.3%], P = 0.03) in CD4+T cells was observed in the PIBO group compared with those in the control group. In CD8+T cells, the proportion of effector memory T cells (7.8% [4.2%–13.8%] vs. 24.3% [15.3%–27.9%], P = 0.02) and CD45RA+effector memory T cells (16.2% [11.0%–36.6%] vs. 24.2% [17.1%–39.7%], P = 0.04) was decreased in the patient group compared with the control group. Conclusion It is suggested that T lymphocyte subset abnormalities may be associated with a decrease in the ability to differentiate the T cells immediately upon reinfection and induce an effective response to infection. These results may partially explain the pathophysiological individual vulnerabilities to PIBO after lower respiratory tract infections in children.
