Chronic myelogenous leukemia is a neoplastic proliferation of the granulocytic series. In Mexico, chronic myelogenous leukemia accounts for approximately 10% of all leukemias. Tyrosine-kinase inhibitors are considered front-line therapy in high-income countries, whereas allogeneic hematopoietic stem cell transplantation is a recognized therapeutic approach, mainly in low- and middle-income countries. ⋯ Tyrosine-kinase inhibitors were significantly superior to allogeneic hematopoietic stem cell transplantation in prolonging the overall survival of persons with chronic myelogenous leukemia in our single institution experience.

Background: Since to the prognosis of lung squamous cell carcinoma is generally poor, there is an urgent need to innovate new prognostic biomarkers and therapeutic targets to improve patient outcomes. Objectives: Our goal was to develop a novel multi-gene prognostic model linked to neutrophils for predicting lung squamous cell carcinoma prognosis. Methods: We utilized messenger RNA expression profiles and relevant clinical data of lung squamous cell carcinoma patients from the Cancer Genome Atlas database. ⋯ Tumor immune dysfunction and exclusion scores and immunophenoscore results suggested a potential inclination toward immunotherapy in the "RIC" version V2 revised high risk group. Moreover, prediction results from the CellMiner database revealed great correlations between drug sensitivity (e.g., Vinorelbine and PKI-587) and prognostic genes. Conclusion: Overall, our study established a reliable prognostic risk model that possessed significant value in predicting the overall survival of lung squamous cell carcinoma patients and may guide personalized treatment strategies.

Random renal biopsy is considered the gold standard for the diagnosis of systemic renal disorders. Percutaneous biopsy remains a safe option for most patients; however, the percutaneous approach may be considered too risky in approximately 5-10% of patients. ⋯ When performed properly, TJRB is a safe alternative to percutaneous biopsy in patients with renal failure or who are at high risk of bleeding. This article aims to provide a comprehensive review of the indications, techniques, precautions, and complications of TJRB, a possibly underutilized technique. (Rev Invest Clin. 2024;76(5):207-12).

Human immunodeficiency virus (HIV) drug resistance is a major cause of treatment failure in children and adolescents infected with the virus. ⋯ In Argentina, HIVDR observed in children and adolescents has decreased over the past 15 years, regardless of the viral subtype.

Observational Study
Assessment of Osteoprotegerin and Receptor Activator of Nf-Κb Ligand in Malaysian Male Patients with Chronic Obstructive Pulmonary Disease: A Cross-Sectional Study.
Background: Limited information exists regarding the pathophysiological interactions between osteoporosis and chronic obstructive pulmonary disease (COPD). Objective: To study the association of Osteoprotegerin (OPG) and receptor activator of nuclear factor kappa-Β ligand (RANKL) in male COPD patients. Methods: An observational clinical study was conducted at Penang General Hospital in Malaysia. ⋯ Furthermore, patients with severe COPD had a 3 times greater risk of developing osteoporosis (OR = 2.997 [95% CI = 2.181, 4.118], p < 0.001), while spirometric parameters had a significant inverse relationship with osteoporosis (FEV1% OR = 0.970, [95% CI = 0.954, 0.986], p = 0.001; FEV1/FVC OR = 0.984, (95% CI = 0.970, 0.999], p = 0.035). Conclusion: The study concluded that COPD patients had lower sOPG levels, leading to decreased OPG/RANKL ratio and faster bone resorption. Low bone mineral density was associated with more severe COPD. (Rev Invest Clin. 2024;76(6):262-73).
