PSTS-h
Primary malignant cardiac tumors are rare, with a prevalence of about 0.01% among all cancer histotypes. At least 60% of them are primary soft tissue sarcomas of the heart (pSTS-h) that represent almost 1% of all STSs. The cardiac site of origin is the best way to classify pSTS-h as it is directly linked to the surgical approach for cancer removal. Indeed, histological differentiation should integrate the classification to provide insights into prognosis and survival expectancy of the patients. The prognosis of pSTS-h is severe and mostly influenced by the primary localization of the tumor, the difficulty in achieving complete surgical and pharmacological eradication, and the aggressive biological features of malignant cells.

Radioiodine-Refractory Thyroid Cancer
Recurrent, metastatic disease represents the most frequent cause of death for patients with thyroid cancer, and radioactive iodine (RAI) remains a mainstay of therapy for these patients. Unfortunately, many thyroid cancer patients have tumors that no longer trap iodine, and hence are refractory to RAI, heralding a poor prognosis. RAI-refractory (RAI-R) cancer cells result from the loss of thyroid differentiation features, such as iodide uptake and organification. This loss of differentiation features correlates with the degree of mitogen-activated protein kinase (MAPK) activation, which is higher in tumors with BRAF (B-Raf proto-oncogene) mutations than in those with RTK (receptor tyrosine kinase) or RAS (rat sarcoma) mutations. Hence, inhibition of the mitogen-activated protein kinase kinase-1 and -2 (MEK-1 and -2) downstream of RAF (rapidly accelerated fibrosarcoma) could sensitize RAI refractivity in thyroid cancer. However, a significant hurdle is the development of secondary tumor resistance (escape mechanisms) to these drugs through upregulation of tyrosine kinase receptors or another alternative signaling pathway. The sodium iodide symporter (NIS) is a plasma membrane glycoprotein, a member of solute carrier family 5A (SLC5A5), located on the basolateral surfaces of the thyroid follicular epithelial cells, which mediates active iodide transport into thyroid follicular cells.

Obesity-Induced Perivascular Adipose Tissue Dysfunction in Vascular Homeostasis
Perivascular adipose tissue (PVAT) is an additional special type of adipose tissue surrounding blood vessels. Under physiological conditions, PVAT plays a significant role in regulation of vascular tone, intravascular thermoregulation, and vascular smooth muscle cell (VSMC) proliferation. PVAT is responsible for releasing adipocytes-derived relaxing factors (ADRF) and perivascular-derived relaxing factors (PDRF), which have anticontractile properties.

Bone Biochemical Immune Parameters in Marrow Immune Microenvironment
The bone marrow (BM), the major hematopoietic organ in humans, consists of a pleiomorphic environment of cellular, extracellular, and bioactive compounds with continuous and complex interactions between them, leading to the formation of mature blood cells found in the peripheral circulation. The bone marrow (BM) microenvironment regulates normal hematopoiesis and exerts variable activity in various inflammatory, toxic, autoimmune, or neoplastic diseases and conditions. It has a major role in the pathogenesis of BM failure syndromes and particularly of myelodysplastic syndromes (MDS).

Sex-Related Differences in Anti-Inflammatory Drugs
There is increasing evidence of sex differences in the action of anti-inflammatory drugs, with women being at significantly higher risk of adverse effects. Nevertheless, clinicians’ awareness of the implications of these sex differences on dosing and adverse event monitoring in routine practice is still in need of improvement.

The Side Effects Reported after COVID-19 Immunization
Studies found that all immunizations were safe, with very few or no Side Effects (SEs); however, the form of SEs was shown to be more persistent in DNA- and mRNA-based vaccines, whereas inactivated viral vaccines were associated with longer-duration SEs. Overall, SEs were shown to be more prevalent in women and youngsters. Certain instances of adverse responses have also been observed, although their pathological relationship with COVID-19 immunization has yet to be determined.

MHealth Solutions for Type2 Diabetes
According to WHO (2008), mHealth can be defined as mobile computing, medical sensor, and communication technologies for health care. mHealth employs various features, including SMS text messages, emails, phone calls, and mobile phone apps. Therefore, this technology’s potential use is evident, both for the general population and clinical samples, since it is employed to improve healthy behaviors and self-care in many medical conditions.

Microbiome-Brain-Gut Axis in the Pathogenesis of Depressive Disorder
The brain and gut, through the microbiota, can influence each other’s functions via neuroendocrine, neuroimmune and sensory-neural molecular pathways. Moreover, both hypothalamic-pituitary-adrenal (HPA) axis and gut peptides might be involved in this communication system.

Surgically Resectable NSCLC
Early-stage NSCLC (stages I and II, and some IIIA diseases) accounts for approximately 30% of non-small cell lung cancer (NSCLC) cases, with surgery being its main treatment modality. The risk of disease recurrence and cancer-related death, however, remains high among NSCLC patients after complete surgical resection. In previous studies on the long-term follow-up of post-operative NSCLC, the results showed that the five-year survival rate was about 65% for stage IB and about 35% for stage IIIA diseases. Platinum-based chemotherapy with or without radiation therapy has been used as a neoadjuvant therapy or post-operative adjuvant therapy in NSCLC, but the improvement of survival is limited. Immune checkpoint inhibitors (ICIs) have effectively improved the 5-year survival of advanced NSCLC patients. Cancer vaccination has also been explored and used in the prevention of cancer or reducing disease recurrence in resected NSCLC.

Common Variable Immunodeficiency
Inborn errors of immunity (IEI) are multifaced diseases which can present with a variety of phenotypes, ranging from infections to autoimmunity, lymphoproliferation, and neoplasms. In recent decades, research has investigated the relationship between autoimmunity and IEI. Autoimmunity is more prevalent in primary humoral immunodeficiencies than in most other IEI and it can even be their first manifestation. Among these, the two most common primary immunodeficiencies are selective IgA deficiency and common variable immunodeficiency (CVID).
