Background.: Oncology clinical trials demonstrate the risk of cardiotoxicity but are not sufficient to reveal the true risk. In this article, we compared the incidence of cardiotoxicity of crizotinib and osimertinib from a real-world study to data reported by phase 3 clinical trials.

Cardiotoxicity induced by anti-cancer treatment has become a significant threat as the number of cardiotoxic anti-cancer agents is growing. Cancer patients are at an increased risk of contracting coronavirus disease 2019 (COVID-19) because of immune suppression caused by anti-cancer drugs and/or supportive treatment. Deterioration in lung functions due to COVID-19 is responsible for many cardiac events.

Generalized epileptic convulsions frequently exhibit transient respiratory symptoms and non-infectious leukocytosis. While these peri-ictal effects appear to arise independently from one another, the possibility that they stem from a common ictal pathophysiological response has yet to be explored. We aimed to investigate whether peri-ictal respiratory symptoms and postictal leukocytosis coexist.

South Asians have a greater cardiovascular disease (CVD) and type 2 diabetes (T2D) risk than white Europeans, but the mechanisms are poorly understood. This study examined ethnic differences in free fatty acids (FFAs) metabolic profile (assessed using liquid chromatography-mass spectrometry), appetite-related hormones and traditional CVD and T2D risk markers in blood samples collected from 16 South Asian and 16 white European men and explored associations with body composition, objectively-measured physical activity and cardiorespiratory fitness. South Asians exhibited higher concentrations of five FFAs (laurate, myristate, palmitate, linolenic, linoleate; ≤ 0.

Objective: To evaluate the frequency of HLA class I and II alleles associated with traditional forms of inflammatory arthritis in patients with immune checkpoint inhibitor (ICI)-induced inflammatory arthritis as compared with population controls.

Methods: High-resolution HLA typing was performed on 27 patients with ICI-induced inflammatory arthritis and 726 healthy controls. Genotyping at the shared epitope (SE) locus (HLA DRB1) was performed on 220 RA cases.

The power of cancer immune surveillance has been documented beyond doubt, and the successful exploitation of immune response to cancer has started a new era in the war against cancer. Cancer biologists have recognized immunoevasion as an emerging hallmark in addition to the six hallmarks of cancer. Besides the natural connection between the immune system and cancer development, most established environmental risk factors are now known to interfere with immune surveillance mechanisms.

Childhood acute lymphoblastic leukemia (ALL) occurs more frequently in males. Reasons behind sex differences in childhood ALL risk are unknown. In the present genome-wide association study (GWAS), we explored the genetic basis of sex differences by comparing genotype frequencies between male and female cases in a case-only study to assess effect-modification by sex.

Article Synopsis
  • - The study focused on how certain genetic variations (polymorphisms) in the PPARGC1A gene relate to the risk of developing type 2 diabetes (T2D) among Haitian Americans and African Americans in South Florida.
  • - Findings revealed that two specific genetic variants, rs7656250 and rs4235308, had a protective effect against T2D in Haitian Americans but increased risk in African Americans; highlighting distinct genetic influences in these groups.
  • - Further analysis by sex showed that these variations also had varying protective effects between genders, emphasizing the need for more research with larger sample sizes to better understand these differences in the Black population.

Birth characteristics such as birth order, birth weight, birth defects, and Down syndrome showed some of the first risk associations with childhood leukemia. Examinations of correlations between birth characteristics and leukemia risk markers have been limited to birth weight-related genetic polymorphisms. We integrated information on nongenetic and genetic markers by evaluating the relationship of birth characteristics, genetic markers for childhood acute lymphoblastic leukemia (ALL) susceptibility, and ALL risk together.

We report a positive association between HLA-DRB1*15 (p= 0.0002) in Turkish patients with pediatric severe aplastic anemia (SAA) and a paradoxically favorable influence of the susceptibility marker on the clinical response to immunosuppressive therapy. These findings point to an immune mechanism mediated by DRB1*15 in SAA which confers responsiveness to treatment.
