UNDERSTANDING THE LONG-TERM INTERPLAY BETWEEN GLUCOCORTICOIDS, PARATHYROID HORMONE LEVELS, AND OSTEOPOROSIS IN PATIENTS.

Drugs called glucocorticoids (GC) are often prescribed for both inpatient and outpatient settings. They are often used to treat a number of disorders due to their anti-inflammatory activity. Long-term use of GCs, especially long-term high-dose administrations, may result in a variety of negative effects. In Hilla City, Babylon Governorate of Iraq, Merjan Teaching Hospital, Al-Hilla Teaching Hospital's Joint Enology Clinic, and Al-Imam Al-Sadiq Hospital, were the sites of this case-control research, which was carried out. There were 100 total participants in this trial, of whom 50 were patients with osteoporosis (OP). The ages of the patients and the control collection were. They were chosen since their gender and ages matched. The findings show extensively senior level of parathyroid hormone (PTH) in OP patients when compared to the control group, whereas calcium (Ca) level into the patient group significantly lowered during association toward the manage set. In summary, there is a positive correlation between PTH and the condition of bone mineralization. In those who use GCs for a long time, PTH may be used as a prognostic marker to predict when bone mineral abnormalities would develop.

THE ROLE OF IMMUNOTHERAPY IN CANCER TREATMENT: CHECKPOINT INHIBITORS, CAR-T CELLS, AND VACCINES.

Immunotherapy causes cancer patients' immune systems to activate in search of and eliminate cancer cells. As a therapeutic area for cancer, it has expanded in importance and demonstrated promising results in treating many cancers. Checkpoint blockade (CPB) therapy may stimulate a suppressed immune response to provide long-lasting therapeutic results. However, the absence of a tumor-reactive immune infiltration is probably why response rates are still low. Using chimeric antigen receptor (CAR)-modified T cells to fight cancer may significantly impact immunology. This study explored using checkpoint inhibitors, car-T cells, and vaccines in immunotherapy to treat cancers. Drugs used for CPB aim to reduce immunological suppression, allowing for more effective CAR T cells and dendritic cell (DC) vaccines, providing some optimism that this may be increased, both of which have proven therapeutic efficacy in specific cancers. However, drug-induced side effects and the tumor microenvironment's propensity for immunosuppression mean treatment effectiveness is still inadequate. The outcomes of current preclinical tests suggest that novel therapies targeting lymphocyte-activation gene 3 (LAG3), T cell immunoglobulin and mucin-domain containing-3 (TIM3), cytotoxic T lymphocyte-associated protein 4 (CTLA-4), and programmed cell death protein 1 (PD-1) could be used as adjuvant therapies to modify the tumor microenvironment.
