Forty-one families with multiple cases of de novo acute myeloid leukemia (AML), B-cell acute lymphocytic leukemia (B-ALL), or both are presented. The families were randomly collected from physicians, genetic counselors, and other sources. Medical records were collected and reviewed for all families. ⋯ Curiously, this is not true of those in the AML-B-ALL group. Four of the 41 families had contributions to more than 1 family relationship category. Although inheritance in familial acute leukemia has usually been consistent with an autosomal dominant pattern, these data suggest that an X chromosome gene may be involved in some cases, perhaps in the pseudoautosomal region of the X chromosome as we have reported in familial Hodgkin lymphoma.

Hepatocellular carcinoma (HCC) is a prevalent form of primary liver cancer with a 5-year survival rate of just 18%. Ferulic acid, a natural compound found in fruits and vegetables such as sweet corn, rice bran, and dong quai, is an encouraging drug known for its diverse positive effects on the body, including anti-inflammatory, anti-apoptotic, and neuroprotective properties. Our study aimed to investigate the potential antitumor effects of ferulic acid to inhibit tumor growth and inflammation of HCC in rats. ⋯ In conclusion, ferulic acid is believed to possess antitumor properties by inhibiting HCC-induced hypoxia through the suppression of HIF-1α expression. Additionally, it helps in reducing the expression of mTOR, STAT3, cMyc, and cyclin D1, thereby slowing down tumor growth. Lastly, ferulic acid reduced hepatic tissue inflammation by downregulating NFκB and TNF-α.

There is little evidence of antimicrobial elimination via therapeutic plasma exchange (TPE) and no guidelines for antimicrobial optimal dosing in patients undergoing TPE. We aimed to assess current practices and knowledge regarding antimicrobial management during TPE. A structured online survey was conducted from May to November 2023, and physicians were invited to participate through national scientific platforms and professional societies. ⋯ The core questions regarding potential drug-, procedure-, and patient-related antimicrobial elimination factors via TPE were responded to accurately by less than half of the physicians. It was clear that they had a lack of clinical practices and knowledge regarding antimicrobial management during TPE. To ensure the therapeutic efficacy of antimicrobials and avoid treatment failure, physicians should improve their practice strategies and consider antimicrobial elimination factors with TPE in this data-poor setting.

Clinical research is a key factor in healthcare progress, as it contributes toward improving our knowledge on the prevention, etiology, and treatment of different conditions. Healthcare professionals and researchers should be familiar with this specific terminology and procedures of clinical research to understand and be able to evaluate clinical trial results and make decisions using up-to-date recommendations. ⋯ Additionally, when it comes to communicating the results and publishing them, it is also necessary to know how to do it adequately to ensure transparency. This work includes a description of different concepts commonly used in clinical research, particularly in the clinical trials field, in an attempt to compile different topics by providing a brief and accessible overview.

Iron is an essential element for the biological processes of living organisms, including the production of crucial oxygen-carrying proteins, formation of heme enzymes, and playing roles in electron transfer and oxidation-reduction reactions. It plays a significant role in various cardiovascular functions, including bioenergetics, electrical activity, and programmed cell death. Minor deficiencies of iron have been found to have negative impact on cardiovascular function in patients with heart failure (HF). ⋯ Large, randomized trials and meta-analysis, like Ferinject Assessment in patients with ID and chronic HF, AFFIRM-AHF, IRONMAN, and HEART-FID have demonstrated the efficacy of IV iron supplementation with IV ferric carboxymaltose or IV ferric derisomaltose in reducing hospitalizations and improving quality of life in patients with Heart Failure with reduced ejection fraction (HFrEF), New York Heart Association (NYHA) II-III. However, survival and mortality have demonstrated no improvement during acute exacerbations of HF or in outpatient management. The potential benefits of IV iron across the entire HF spectrum and its interaction with other HF therapies remain areas of interest for further research.
