The prevalence of heart failure has increased significantly in recent years, prompting investigations into novel contributory factors. Among these, alterations in the gut microbiota composition have garnered attention due to their potential association with heart failure. Disruption in the bacterial environment associated with heart failure is characterized by heightened levels of Proteobacteria and Firmicutes and decreased levels of Bifidobacteria and Bacteroides.

Diamond-Blackfan anemia syndrome (DBAS) is a rare inherited bone marrow failure (BMF) syndrome characterized by erythroid aplasia, congenital malformations, and cancer predisposition. With its genetic heterogeneity, variable penetrance and expressivity, DBAS poses significant diagnostic challenges, necessitating advancements in genetic testing for improved accuracy. Here, we present the case of an 18-year-old male with a long-standing macrocytic anemia that remained undiagnosed despite standard whole exome sequencing (WES).

Article Synopsis
  • Prostate cancer is the second most common cancer in men, with various stages ranging from localized to metastatic disease, and treatment for advanced stages typically involves external beam radiotherapy and hormonal therapy for better prognosis.
  • Current therapies for non-metastatic castration-resistant prostate cancer (M0 CRPCa) utilize androgen deprivation combined with new drugs, showing promising results in clinical trials for prolonging metastatic-free survival.
  • New drug developments, including PARP inhibitors and Lutetium-177, along with ongoing clinical trials for treatments like cabozantinib and CAR T-cell therapy, aim to improve overall survival rates and slow disease progression in advanced prostate cancer cases.

β-Thalassemia is brought about by defective β-globin (HBB [hemoglobin subunit β]) formation and, in severe cases, requires regular blood transfusion and iron chelation for survival. Genome editing of hematopoietic stem cells allows correction of underlying mutations as curative therapy. As potentially safer alternatives to double-strand-break-based editors, base editors (BEs) catalyze base transitions for precision editing of DNA target sites, prompting us to reclone and evaluate two recently published adenine BEs (ABEs; SpRY and SpG) with relaxed protospacer adjacent motif requirements for their ability to correct the common splice mutation.

Colorectal cancer (CRC) ranks as the third leading cause of cancer-related mortality worldwide. Recent years have witnessed an increase in the incidence of CRC among adults <50 years old on a global scale. The increased incidence is associated with several modifiable risk factors, including obesity, type II diabetes, physical inactivity and frequent antibiotic use.

Purpose Of Review: Breast cancer (BC) is the leading cause of death among women aged 44-55 years globally. Pro-inflammatory food can cause tissue-level inflammation, thereby creating a carcinogenic microenvironment and promoting breast cancer. The aim of this review is to provide an overview of the association between inflammation and nutrition and clinical outcomes in breast cancer survivors.

Objective: This scoping review will identify barriers and facilitators for the adoption of 7 healthy lifestyle components by female breast cancer survivors. This will be achieved by mapping the World Cancer Research Fund/American Institute for Cancer Research recommendations and the Lifestyle Medicine pillars.

Introduction: Adherence to healthy lifestyle components (including weight management, physical activity, healthy diet, restorative sleep, avoidance of risky substances, forming and maintaining healthy relationships, and stress management) may improve the quality of life of breast cancer survivors and reduce the risk of adverse patient outcomes.

The incidence of thyroid cancer has increased in recent years, leading to a growing number of survivors facing lifelong consequences. This scoping review investigated anxiety, depression, and quality of life (QoL) in thyroid cancer survivors compared to the general population, those with benign pathology, and survivors of other types of cancers. Moreover, we aimed to identify the risk factors associated with anxiety, depression, and QoL in thyroid cancer patients.

Hepatocellular carcinoma is the fourth leading cause of cancer-related deaths worldwide and its associated mortality rate is expected to rise within the next decade. The incidence rate of hepatocellular carcinoma varies significantly across countries and the latter can be attributed to the differences in risk factors that are prevalent across different countries. Some of the risk factors associated with hepatocellular carcinoma include hepatitis B and C infections, non-alcoholic fatty liver disease, and alcoholic liver disease.

Purpose Of Review: Endometrial cancer is the most common gynecological malignancy and represents a notorious threat to women's health worldwide. Endometrial cancer predominantly affects post-menopausal women; yet the prevalence of this disease has been rising also among pre-menopausal women. Poor nutritional habits, inflammation, and obesity may be associated with endometrial cancer (EC) among both pre-menopausal and post-menopausal women and should be further assessed among a wide spectrum of age groups.

Blue Zones are regions of the world that have a higher number of individuals who live longer than the expected average. The current paper revisits principles previously identified to be common in Blue Zones and to be contributing to longevity ( and ), compares these to the 6 pillars of Lifestyle Medicine (, , , , and reviews new studies investigating the association between behavioral factors and longevity. In addition to the role of behavior, the review also discusses the important role of genetics and emphasizes the importance of conducting further research to understand how behavioral and genetic factors may affect molecular pathways with consequent effects on wellbeing and longevity.

The evaluation of courses and faculty is of vital importance in all higher education institutions including medical schools. Student Evaluations of Teaching (SETs) commonly take the form of completion of anonymous questionnaires and even though they were originally developed to evaluate courses and programmes, throughout the years they have also been used to measure teaching effectiveness and subsequently to guide important decisions related to the faculty's career progression. Nevertheless, certain factors and biases may influence SET rates and may not measure teaching effectiveness objectively.
