Extensive Left Ventricular Thrombosis after Recovery from COVID-19: A Case Report.

Coagulation disorder is common among COVID-19 patients, particularly those afflicted with the severe form of the disease. Manifestations of thrombotic complications such as pulmonary embolism, deep vein thrombosis (DVT), ischemic stroke, cardiac infarction and arterial embolism is high in COVID-19 patients which have been assessed in various studies (5).It seems that COVID-19-related coagulopathy is a combination of low-grade DIC and pulmonary thrombotic microangiopathy which can have a significant effect on organ dysfunction in patients with severe COVID-19 (6).

The effect of artificial saliva on the control of dry mouth: a semi-experimental study on COVID-19 patients under Non-invasive mechanical ventilation.

Objectives: Since maintaining oral hygiene is essential in nursing care, the present study was conducted to determine the effect of oral care using Mucosamin artificial saliva spray to control dry mouth in ICU patients with COVID-19.

Materials And Methods: The current semi-experimental research was conducted on eighty patients with COVID-19 selected using the available sampling method. The study tool was a Beck oral assessment scale (BOAS).

Prediction of mortality in ICU patients: A comparison between the SOFA score and other indicators.

The intensive care unit (ICU) is the most important department for critically ill patients. Different scoring systems are used to assess the severity of the disease and evaluate organ failure during the patient's stay in ICU. Our purpose was to evaluate the C-reactive protein/Albumin (CRP/Alb) ratio and SOFA score as indicators of 28-day mortality in ICU patients.

Relationship between Underlying Diseases with Morbidity and Mortality in Patients with COVID-19.

Background: This study aims to investigate the clinical and demographic features of underlying medical conditions and the potential relationship between underlying diseases and the increased rate of morbidity and mortality due to COVID-19.

Materials And Methods: This study was conducted on 350 COVID-19 patients hospitalized at the Masih Daneshvari Hospital from February-July 2021. All participants had confirmed COVID-19 diagnosis based on symptoms and/or positive PCR test or chest X-ray results.

Rapid spread and high mortality due to community-acquired pneumonia caused by (CAP-AB) in a Covid-19 intensive care unit.

is a rare but dangerous gram-negative bacteria causing nosocomial infections, especially in intensive care units. The increased use of antibiotics in the treatment of bacterial infections leads to drug resistance, delays, or failures in treatment. The patient is a 48-year-old man with coronavirus disease (COVID-19) being treated in the intensive care unit.

Hypo and hyperbaric pressure effect on the fracture resistance of three types of dental crowns: PFM, LD, and Y-TZP.

Objectives: Loss of dental restorative materials can lead to severe problems in some occupations, especially diving and piloting. This study aimed to compare the fracture resistance of three types of materials (PFM, LD, and Y-TZP) under hyper and hypobaric conditions to simulate diving and flight and control conditions for introducing a suitable restorative material for individuals under these conditions.

Methods: Three dental crowns related to the upper premolar were prepared.

Impact of various pressures on fracture resistance and microleakage of amalgam and composite restorations.

Background: Pressure changes can influence dental restorations especially among divers. The aim of the current study was to evaluate the fracture resistance and microleakage of mesio-occluso-distal (MOD) amalgam and composite restorations undergoing pressure changes via diving and aviation simulation.

Methods: For the fracture resistance test, 60 sound maxillary premolar teeth were randomly allocated to two groups.

Epidemiology of pemphigus in tehran, iran: a 20-year retrospective study.

Background And Aims: Pemphigus is a chronic autoimmune and vesiculobollous disease that can affect skin and different mucous membrane surfaces. Primary manifestations occur in oral cavity in almost 60% of cases. The purpose of the present study was to evaluate the epidemiology of pemphigus in Tehran, Iran in a 20-year period.
