Despite the availability of iron chelators, toxicity due to increased iron load is the leading cause of death in thalassemia major patients, especially in Iran. This study was performed to determine the association between cardiovascular magnetic resonance using T2-weighted sequences (CMR T2*) and diagnostic value of echocardiographic arterial elasticity in major beta-thalassemia patients without cardiac symptoms in Isfahan, Iran, in 2019 and 2021. ⋯ Totally, according to the obtained results, it may be concluded that the arterial elastance index from echocardiography and the CMR T2* may be indicators of myocardial iron overload in patients with major beta-thalassemia patients without cardiac symptoms.

Ponticulus posticus (PP) (arcuate foramen) is an abnormal bony bridge in the posterior arch of the atlas, which could possibly cause certain complications such as headache. Our goal was to assess the prevalence and size of PP on lateral cephalometric radiographs and its relationships with cervicogenic headache and migraine. ⋯ Our study showed a high prevalence of PP and its significant association with cervicogenic headache and migraine.

Streptococcus mutans involved in caries pathogenesis is classified into four serotypes, namely serotypes c, e, f, and k. Candida albicans can be found in the plaque of children with early childhood caries (ECC). Aims: The aim of this study was to analyze the quantity of the antigens of S. mutans serotype e and C. albicans and its correlation with the salivary flow rate in ECC. ⋯ the antigen quantities of S. mutans serotype e and C. albicans and the salivary flow rate might correlate to the pathogenesis of ECC.

Suitable mechanical ventilation strategies can reduce the incidence and severity of ventilator-associated lung injury in patients with acute respiratory distress syndrome (ARDS). In this study, the effects of adaptive support ventilation (ASV) and synchronized intermittent mandatory ventilation (SIMV) on respiratory parameters and arterial blood gases (ABGs) parameters were compared in ARDS patients. ⋯ By reducing PIP and improving oxygenation and ABG parameters, ASV mode may be a safe and feasible mode during mechanical ventilation in patients with ARDS.

The first confirmed case of COVID-19 in Iran was reported in February 2019. The current study aimed to investigate the epidemiological aspects of COVID-19 disease in Isfahan province and evaluate the chances of infection and death in the population. ⋯ This study showed that people with cancer and chronic respiratory disease had a higher chance of COVID-19 infection. People over the age of 60, people with cancer, and immunodeficiency also had a higher chance of COVID-19 mortalityW.
