Observational Study
Association between serum globulins and diabetes mellitus in American latent tuberculosis infection patients: A cross-sectional study.
Diabetes mellitus (DM) is predisposing to the development of latent tuberculosis infection (LTBI). An understanding of the underlying factors of LTBI-DM is important for tuberculosis prevention and control. This study aims to evaluate the association between LTBI and DM among the noninstitutionalized civilian population in the United States, focusing on the impact of serum globulins. ⋯ The area under the curve for serum globulin predicting DM was 0.795, with an optimal cutoff value of 2.9. Elevated serum globulin levels are significantly associated with an increased risk of DM among individuals with LTBI, highlighting the potential role of serum globulin as a predictive biomarker for DM in this population. However, the specific mechanism between globulin and LTBI-DM needs to be further investigated.

Positive association between constipation and mild cognitive impairment in elders: A cross-sectional study.
This study aimed to examine the association between constipation and mild cognitive impairment (MCI); and further elucidate the possible mechanisms involved. A cross-sectional study was conducted among community-dwelling elders (N = 789) in Nanning, China. Trained research staffs collected detailed information through questionnaires and physical examinations. ⋯ Among these, constipation, history of stroke, and years of schooling were directly related to the occurrence of MCI. Years of schooling indirectly affected MCI through infrequent fruit consumption and constipation; or through inactive physical exercises and history of stroke. This study demonstrates a direct association between constipation and increased risks of MCI.

Serum ACSL4 levels in prostate cancer patients and its relationship between patient prognosis: A prospective observational study.
In this prospective observational study, our objective was to investigate the serum levels of Acyl-CoA synthetase long-chain family member 4 (ACSL4) in prostate cancer (PCa) patients and examine its association with other serum biomarkers, and the clinical outcomes of PCa patients. This prospective observational study was conducted from January 2019 to October 2021, including 103 cases of PCa patients and 101 cases of benign prostate hyperplasia (BPH) patients who received treatment at our hospital. All patients had their serum ACSL4 levels measured using enzyme-linked immunosorbent assay before treatment. ⋯ Finally, we found that ACSL4, tPSA, and P were identified as risk factors associated with PCa patients. Our findings indicated that the serum levels of ACSL4 were significantly decreased in PCa patients compared to BPH patients. Serum ACSL4 could be used as a potential biomarker for early PCa diagnosis and prognosis.

CD8+ T lymphocytes are important elements of the tumor microenvironment, hence their involvement in the development and progression of tumors is complex. Data on the precise tumor-infiltrating lymphocytes gene signature in renal cell carcinoma (RCC) remain limited. Therefore, this study created a tumor-infiltrating lymphocytes-related predictive model for patients with RCC using data from The Cancer Genome Atlas. ⋯ A CD8 + T lymphocyte-related prognostic model with 7 important genes was simultaneously created using the least absolute shrinkage and selection operator, univariate and multivariate Cox regressions, and the 7 genes were expressed particularly in CD8 + T lymphocytes according to single-cell sequencing data obtained from the Gene Expression Omnibus. This study identified a seven-gene prognostic model associated with CD8 + T lymphocytes that may significantly influence risk stratification in patients with RCC. The genes included in the model are apolipoprotein B mRNA editing catalytic polypeptide 3G, CD3 gamma, eomesodermin, protein tyrosine phosphatase, non-receptor type 7, signal regulatory protein gamma, Fas ligand, and T-cell immunoreceptor with Ig and ITIM domains.

Invasive fungal infections in patients with acute leukemia: A retrospective cohort study at a tertiary-care hospital.
Invasive fungal infection (IFI) is an important cause of morbidity and mortality in acute leukemia patients. In the past few decades, the incidence of IFI has dramatically increased. Nevertheless, the management of IFI has become more complicated owing to changes in the epidemiology of fungal diseases and therapeutic regimens. ⋯ Pulmonary involvement is the most common site. Neutropenia, ICU follow-up and MV are associated with an increased risk for IFI and mortality. We recommend in the IFI approach, to be aware of IFI in patients receiving intensive chemotherapy and/or recipients of hematopoietic stem cell transplantation, and to evaluate with microbiological, serological and radiological tests during the clinical follow-up.
