Introduction: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant appeared in South Africa for the first time. The high prevalence of its mortality in elderly patients has caused an increase in anxiety triggered by this disease in aged people. Objectives: The aim of this study is to evaluate the anxiety related-COVID-19 in the SARS-CoV-2 Omicron variant and its related factors in elderly patients who are candidates for cataract surgery. Patients and Methods: This descriptive-analytical study was conducted on 159 over 65 years old patients who are candidates for cataract surgery. Easy and accessible sampling methods were employed to select samples. Demographic characteristics sheet and the Corona Disease Anxiety Scale (CDAS) questionnaire were filled out by them. Fisher’s exact test, Mann-Whitney U and binary logistic regression tests were conducted for data analysis. Results: The results showed that out of 159 patients, 57.9% were female, with a mean age of 73.09 ± 9.64 years. The anxiety level of 70.4% of patients was mild or non-anxiety and 29.6% was moderate or severe. The correlation between anxiety related to COVID-19 with age, gender, vaccination status and history of being infected by COVID-19 was significant (P<0.05); however, the correlation with the job, place of residence and marital status were not significant (P>0.05). Conclusion: We concluded that older age, female gender, non-vaccinated and having no history of being infected by COVID-19 are the most influential factors that increase anxiety triggered by COVID-19 in elderly patients.

Lactic acidosis (LA) due to metformin prescription is a rare condition; however, this circumstance is accompanied by a very high rate of death (≥50%). Accumulation of metformin alone is hardly a cause of LA, and more than 90% of patients with metformin-associated LA had a hypoxic condition that could prompt hazards of LA. LA related to this drug occurs after iodinated contrast material (ICM) exposure when other contraindications to metformin use, particularly renal insufficiency neglected and leading to high plasma metformin accumulation. One of the most common questions for radiologists is when and at what level of kidney function this agent should be discontinued in cases receiving ICM and restarted again. In this study, we assess the requirement of metformin discontinuation in diabetic patients with chronic kidney disease (CKD) who are candidates for ICM. Therefore, we evaluate the step and withholding time of metformin discontinuation in CKD patients programmed for angiography with an intravenous contrast agent. Results demonstrated that for patients with uncertain renal function and individuals with normal estimated glomerular filtration rate and other diseases, the assessment to discontinue metformin (Before or at the time of the procedure) and when to reinitiate this drug should be made the decision, based on the individual’s circumstances.

It is essential to manage hypertension in cancer patients because uncontrolled high blood pressure can increase the risk of cardiovascular complications and negatively impact overall health. We searched PubMed, Web of Science, EBSCO, Scopus, Google Scholar, Directory of Open Access Journals (DOAJ), and Embase, using keywords including; hypertension, onco-hypertension, and Neoplasms; and found that several factors can contribute to the development of onco-hypertension, including certain types of cancer, chemotherapy drugs, targeted therapies, and hormonal treatments. Favorable cooperation of multi-specialists in this disease treatment can lead to better and more optimal treatment management for these patients.

Hyperparathyroidism is a condition where the parathyroid glands produce excess parathyroid hormone, increasing calcium levels in the blood. Chronic hypercalcemia due to hyperparathyroidism has been linked with an increased risk of cardiovascular disease and other vascular complications such as hypertension, atherosclerosis, and thrombosis.
