Hematological and Biochemical Laboratory Parameters in COVID-19 Patients: A Retrospective Modeling Study of Severity and Mortality Predictors.

Background: It is well known that laboratory markers could help in identifying risk factors of severe illness and predicting outcomes of diseases. Here, we performed a retrospective modeling study of severity and mortality predictors of hematological and biochemical laboratory parameters in Iranian COVID-19 patients.

Methods: Data were obtained retrospectively from medical records of 564 confirmed Iranian COVID-19 cases.

Effect of Rosiglitazone, the Peroxisome Proliferator-Activated Receptor (PPAR)-γ Agonist, on Apoptosis, Inflammatory Cytokines and Oxidative Stress in pentylenetetrazole-Induced Seizures in Kindled Mice.

A growing body of evidence has shown that seizure can trigger inflammatory cascades through increasing the expression of several inflammatory cytokines. It has been proved that peroxisome proliferator-activated receptor-γ agonists have immunomodulatory, anti-inflammatory, and neuroprotective effects beyond the putative hypoglycemic effects. Thus, we investigated the inhibitory effect of rosiglitazone on the development of pentylenetetrazol (PTZ)-induced kindling via affecting the inflammatory pathway.

Association between blood groups and COVID-19 outcome in Iranian patients.

Many factors have been speculated to explain the COVID-19 complex clinical phenotype. Due to the inconsistent data published on blood groups and COVID-19, we conducted a study on Iranian patients to further assess this association. This retrospective study was conducted on data collected from confirmed COVID-19 hospitalized patients during March and December 2020 in a referral hospital for COVID-19, 5 Azar Hospital, Gorgan, north of Iran.

Prevalence of Gram-Negative Bacilli Isolated from the Equipment and Surfaces in Hospital Wards of Golestan Province, North of Iran.

Nosocomial infections are one of the most common causes of death in hospitals. This study aimed to determine the prevalence of gram-negative bacilli isolated from the equipment in hospital wards of the Golestan province, in the year 2015. In this cross-sectional study in 2015, 1980 samples from medical and nonmedical equipment and surfaces were collected from the wards of 13 teaching hospitals, in the Golestan province.

The effect of deoxyribonucleic acid extraction methods from lymphoid tissue on the purity, content, and amplifying ability.

Background: Nowadays, definitive diagnosis of numerous diseases is based on the genetic and molecular findings. Therefore, preparation of fundamental materials for these evaluations is necessary. Deoxyribonucleic acid (DNA) is the first material for the molecular pathology and genetic analysis, and better results need more pure DNA.

The results of photorefractive keratectomy with Mitomycin-C in myopia correction after 5 years.

Objective: To evaluate the results of photorefractive keratectomy (PRK) with mitomycin C in myopia correction after five years.

Methods: This is a cross sectional study which included 145 eyes of 74 patients in 18 to 51 years age group that were undergoing Photorefractive keratectomy with mitomycin C using Allegretto Wave Eye-Q 400-Hz excimer laser platform in Markazi Eye Center, Tehran, Iran. All the surgical procedures were performed by the same surgeon.

Compliance with hepatitis B vaccination among adult males with sexually transmitted infections.

Background: Sexually transmitted infections (STIs) are a diverse group of infections caused by widely differing microorganisms (viruses, protozoa, bacteria, yeasts, ectoparasites and even a nematode), with transmission from person to person by sexual contact as its common characteristic. In all societies, sexually transmitted infections rank among the most common infectious diseases. These patients are at risk for hepatitis B virus infection, but have been relatively neglected in terms of hepatitis B virus vaccination.

Computer and Internet use among Undergraduate Medical Students in Iran.

Objective: Although computer technologies are now widely used in medicine, little is known about its use among medical students in Iran. The aim of this study was to determine the competence and access to computer and internet among the medical students.

Methods: In this descriptive study, medical students of Shahid Sadoughi University of Medical Science, Yazd, Iran from the fifth years were asked to answer a questionnaire during a time-tabled lecture slot.

Cutaneous leishmaniasis of the eyelid: a case report.

Cutaneous leishmaniasis is endemic in certain areas of Iran, and in recent years, there has been an increase in the number of reports for rare and new forms of cutaneous leishmaniasis. We describe one unusual clinical form of cutaneous leishmaniasis. In a 27-year-old man, who noted a pimple on the upper eyelid 4 months before.

Occupational hazards to dental staff.

Dental professionals are predisposed to a number of occupational hazards. These include exposure to infections (including Human Immunodeficiency Virus and viral hepatitis); percutaneous exposure incidents, dental materials, radiation, and noise; musculoskeletal disorders; psychological problems and dermatitis; respiratory disorders; and eye insults. Percutaneous exposure incidents remain a main concern, as exposure to serious infectious agents is a virtual risk.

Nursing and midwifery students' approaches to study and learning.

Aim: This paper reports an investigation of the approaches to study and learning of nursing and midwifery students at a school of nursing and midwifery in Iran.

Background: Current knowledge suggests that students approach their studies in surface, deep or strategic manners. Students' approaches to study have an important impact on their academic success.
