Recent Advances in CAR-T Therapy.

Chimeric antigen receptor T cell therapy is used to treat hematological malignancies which are refractory to standard therapy. It is a form of immunotherapy in which a patient's T cells are programmed to act against tumor cells. We discuss the process of manufacturing CAR-T cells, the common side effects of therapy, and the recent emerging risk of T-cell malignancies after treatment.

Role of SGLT2 Inhibitors, DPP-4 Inhibitors, and Metformin in Pancreatic Cancer Prevention.

Pancreatic carcinoma is a highly aggressive tumor that usually presents when it has already metastasized. Therapeutic options for cure remain scarce and rely on combination chemotherapy with limited sustainability. Diabetes is considered an important risk factor for the development of pancreatic cancer due to the production of proinflammatory cytokines, which result in increased cell proliferation. More than half of patients diagnosed with pancreatic cancer eventually develop diabetes due to the destruction of insulin-producing cells. The interlinkage of both diseases might identify a possible preventative strategy for reducing the incidence of pancreatic carcinoma. This study reviewed the recent literature on the association between pancreatic cancer risk and SGLT2 inhibitors, GLP-1 RA, DPP-4 inhibitors, and biguanides. There are mixed data regarding the relationship between GLP-1 RA and DPP-4 inhibitors and pancreatic cancer, with some trials suggesting that they might increase the risk. In contrast, studies have mostly revealed that SGLT2 inhibitors have an antiproliferative effect on various tumors, such as liver, pancreatic, prostate, bowel, lung, and breast carcinoma, which might be due to their mechanism of blockage of reabsorption of glucose by cells, lowering the amount of available glucose for the growth of tumor cells. Metformin, the first-line agent for diabetes, has also been shown to be associated with decreasing pancreatic cancer risk and improving prognosis in those who already have the disease. Dedicated trials are needed to further delineate the association of antidiabetic drugs with the risk of pancreatic cancer in the general population, as previous studies have mostly focused on diabetic patients.

Knowledge and attitudes about burn complications in medical students.

Burn injury in developing countries is a major cause of morbidity and mortality. Pakistan faces a widespread problem of burn complications. The objective of this cross sectional study was to assess knowledge and attitudes in medical students regarding burn complications. A 12-question survey was distributed among 3rd, 4th and 5th year students of public sector medical colleges of Karachi, Pakistan. Out of 353 respondents, the proportion of students that were aware of burn complications was the following, with an expected response of 100% for each complication: depression [86%], fear [53.3%], post-traumatic stress disorder [40.8%], suicidal tendencies [35.1%], sleep disorder [30%], anxiety [27%], guilt [12.7%], personality changes [7%], eating disorder [5.4%], cardiac arrest [68%], hypothermia [64.3%], contractures [61%], infection [43.6%], chronic pain [41.6%], scarring [33%], chronic inflammation [24.9%], and muscle wasting [22.9%]. Most students were of the view that scarring occurs in third-degree burns [68%] only; being unaware of its presence in second-degree burns. 19.3% of the students incorrectly thought that surgery is needed for the healing of all burn patients. There appears to be a lack of basic knowledge about the physiological and psychological complications of burns among medical students of Pakistan.
