With an increasing prevalence driven by indoor air pollution, tobacco use, and occupational hazards, COPD remains underdiagnosed underdiagnosed and undertreated in the region due to inadequate healthcare infrastructure and resource constraints. This review highlights the critical role of medical gases, particularly long-term oxygen therapy (LTOT), in managing COPD, improving quality of life, and reducing mortality in patients with severe hypoxemia. Although LTOT is well-established in high-income countries, its implementation in SSA faces significant barriers, including limited access, cost, and insufficient awareness. This review analyzes COPD management, LTOT benefits, healthcare policies, and aging demographics in SSA, focusing on experimental studies and synthesizing data for coherence. Relevant articles in English published from 2014 to 2025 were retrieved from PubMed, Scopus, and WHO. Through a comprehensive analysis of the epidemiology of COPD in SSA, the challenges of integrating LTOT, and successful case studies from comparable regions, this review identifies key opportunities for addressing these gaps. Recommendations include strengthening healthcare infrastructure, fostering policy frameworks for LTOT integration, leveraging community engagement, and enhancing patient education.

Poor prognosis in breast cancer patients is often linked to the presence of intratumoral hypoxic areas caused by abnormal vascularization and insufficient oxygen availability, which results in energetic crisis in cancer cells; metabolic and epigenetic reprogramming; the transcription of genes involved in angiogenesis; cancer cell proliferation; increased motility, aggressiveness and metastasis; the accumulation of mutations; genomic instability; the maintenance of stem cell characteristics; stromal cell recruitment; extracellular matrix remodeling; chronic inflammation; immune evasion; and adaptive responses in the tumoral microbiota. Furthermore, hypoxia is often correlated with resistance to traditional antitumor treatments used alone or in combination, which results in the need to implement novel therapies to overcome or alleviate the negative effects of oxygen deprivation in breast cancer theranostics. In breast cancer modeling research, micro- and nanofabrication-based technologies, including breast cancer-on-chip and breast cancer metastasis-on-chip platforms, are able to recapitulate the metastatic cascade of breast cancer in different controlled oxygen gradients. Mass spectrometry-based proteomics, including mass spectrometry imaging, offers opportunities for detecting, quantifying and understanding the roles of proteins and peptides, protein-protein interaction networks, and posttranslational modifications of proteins involved in hypoxia-associated biopathological processes. In this mini-review, we have summarized several modern approaches that are able to overcome the undesirable effects of hypoxia for breast cancer treatment. Thus, natural compounds with inhibitory effects on hypoxia-related signaling pathways in breast cancer cells and the tumor microenvironment, hyperbaric oxygen therapy, viral vector-based therapy that uses genetically engineered oncolytic viruses, and oncological bacteriotherapy based on biohybrid platforms, including anaerobic bacteria that are able to colonize inaccessible hypoxic regions in breast tumors to deliver chemotherapeutic drugs just into the tumor site, and smart nanoplatforms for abundant O2 generation within hypoxic breast cancer areas, including erythrocyte-like nanoparticles, metal-organic framework-nanoparticles, or engineered microalgae-metal-organic framework oxygenators, have been designed to relieve tumor hypoxia, induce antitumor responses, and improve the effects of traditional anti-breast cancer therapies.</p>","PeriodicalId":18559,"journal":{"name":"Medical Gas Research","volume":"16 1","pages":"41-45"},"PeriodicalIF":3.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144528730","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Core decompression (CD) restores the blood supply through pressure relief, whereas hyperbaric oxygen (HBO) enhances tissue oxygenation and promotes bone repair. Their combined use may complement each other in improving blood supply, promoting bone healing, and inhibiting disease progression, thus achieving a better therapeutic effect. To assess and compare the efficacy of HBO and/or CD for treating mild to moderate femoral head avascular necrosis, a retrospective study was conducted on patients diagnosed with Ficat stage II non-traumatic osteonecrosis between January 2017 and January 2022 at the Affiliated Central Hospital of Shenyang Medical University, China. A total of 72 patients were divided into HBO, CD, and combination groups, with 24 patients in each group. After 1 year of follow-up, 90% of patients in the HBO group, 85% in the CD group, and 95% in the combination group showed satisfactory improvements in hip joint function. The SF-36 quality of life questionnaire scale scores also significantly improved in all three groups, with the combination group showing the most significant improvement. These findings suggest that HBO offers promising potential for treating non-traumatic femoral head necrosis, with efficacy similar to that of CD.

FK-506 binding protein (FKBP5) is a critical regulator of the hypothalamic-pituitary-adrenal axis and has been implicated in postoperative cognitive dysfunction. However, how inhalation anesthetics affect the expression and function of FKBP5 in the brain is unclear. We employed single-nucleus RNA sequencing to delineate the hippocampal transcriptomic profiles of the brains of aged marmosets and mice after sevoflurane anesthesia. The results of single-nucleus RNA sequencing revealed that long-term exposure (6 hours) to sevoflurane significantly increased FKBP5 expression in the hippocampus of aged marmosets and mice, especially in microglia. Western blot assay also verified the above results. The Barnes maze test showed that, compared with heterozygous control mice, microglia-specific FKBP5 conditional knockout mice exhibited improved neurocognitive function after sevoflurane/surgery. Transcriptome sequencing analysis was performed on the brains of microglia-specific FKBP5 conditional knockout mice and heterozygous mice after sevoflurane/surgery and further revealed that FKBP5 was related mainly to inflammatory signaling pathways.

Nevertheless, little is known about the effects of the interaction between hospitals of the same or different type on patient health outcomes. This study estimated the impacts of aggregate and specific types of hospital competition by hospital-type on the quality of inpatient care using an analysis dataset comprising 267,183 individuals from China. The Herfindahl-Hirschman index was employed to measure the degree of hospital competition, with length of stay, readmission and mortality being used to measure the quality of inpatient care. The Poisson and binomial logistic models combined with the instrumental variable approach were constructed to estimate the impacts of hospital competition. This study generated three key findings: 1) aggregate hospital competition reduced the quality of inpatient care, as evidenced by a rise in the odds of readmission and length of stay; 2) intra-type hospital competition reduced the quality of inpatient care and in general had larger effects on reducing the quality of inpatient care than inter-type hospital competition; and 3) the only exception was in the way that competition between private nonprofit hospitals contributed to better quality of inpatient care.
