The neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), derived neutrophil-to-lymphocyte ratio (dNLR), neutrophil-to-lymphocyte and platelet ratio (N/LP ratio), aggregate index of systemic inflammation (AISI), systemic inflammation response index (SIRI), and systemic inflammation index (SII) have emerged as noteworthy determinants in evaluating the severity and mortality prognosis of inflammatory diseases. In order to predict mortality rate, this study aimed to assess the impact of systemic inflammatory markers on both men and women who were admitted to the hospital due to SARS-CoV-2 infection. The laboratory parameters of the 2007 COVID-19 patients were analyzed in a retrospective study (men = 1145 and women = 862).

Malignancy, bone marrow and organ transplantation are associated with deficient and defective immune systems. Immunocompromised patients are at risk for severe and chronic complication of COVID-19 infection. However, the pathogenesis, diagnosis and management of this comorbidity remain to be elucidated.

Despite studies indicating that asthma patients do not exhibit a higher mortality rate or severity compared to the general population when infected with COVID-19, there have been few reports on predictive factors for mortality in this context. This study aimed to assess the predictive value of systemic inflammation indices including neutrophil-to-lymphocyte (NLR), monocyte-to-lymphocyte (MLR), platelet-to-lymphocyte (PLR), systemic inflammation response index (SIR-I), and systemic inflammation index (SII) in determining mortality rate among patients with COVID-19 and asthma. In this prospective study, the laboratory parameters of 1792 COVID-19 patients were examined, with a subgroup consisting of 112 patients with asthma and 1680 patients without asthma.

Background: Knee arthroplasty is an orthopedic surgical procedure in which a damaged joint is replaced with an artificial one. It is estimated that 1-2% of knee arthroplasties will encounter infection over their lifetime. Although α-hemolytic Streptococcus species play an important role in prosthetic joint infection, they are less common than staphylococcal species.

Background: Drug-induced liver injury is an acute or chronic liver damage in response to drugs, herbals, and any chemical compound.

Case Presentation: In the present work, liver failure following the use of tofacitinib was reported. The patient was an 18-year-old iranian woman without any history of underlying disease.

Background: Lipid profile and its related ratios such as total cholesterol (TC), low-density lipoprotein-cholesterol (LDL-C), triglyceride (TG), high-density lipoprotein-cholesterol (HDL-C), TG/HDL-C ratio, TC/HDL-C ratio, LDL-C/HDL-C ratio, white blood cell (WBC)/HDL-C ratio, and fasting blood glucose (FBG)/HDL-C ratio are valuable indicators that have been studied in various disorders to predict mortality. The present study was conducted with the aim of investigating the role of lipid profile ratios in predicting mortality in COVID-19 patients.

Methods: At the beginning of hospitalization, laboratory tests were taken from all patients ( = 300).

Shigellosis is one of the acute bowel infections and remains a serious public health problem in resource-poor countries. The present study aimed to survey the distribution of extended-spectrum β-lactamase (ESBL)-producing Shigella strains isolated from patients with diarrhea in northwest Iran. In the present cross-sectional study, from January 2019 to December 2020, 1280 fecal samples were collected from children with diarrhea in Ardabil, Iran.

Background: Infection with COVID-19 has resulted in considerable mortality all around the world. This study aimed to investigate the effect of convalescent plasma on the treatment of hospitalized patients with COVID-19 in Imam Khomeini Hospital at Ardabil, Iran.

Materials And Methods: In this quasi-experimental clinical trial, patients over 18 years of age with polymerase chain reaction-positive COVID-19 were admitted based on the clinical criteria of respiratory distress with hypoxia (O saturation <90) and tachypnea (R Relative Risk (RR) >24) with moderate-to-severe lung involvement and in the 1 week of respiratory disease who were not intubated were nonrandomly assigned to two groups: convalescent plasma therapy (CPT) group (197 cases) and control group (200 cases).

Background: Systemic inflammation indices, including neutrophil/lymphocyte ratio (NLR), monocyte/lymphocyte ratio (MLR), platelet/lymphocyte ratio (PLR), derived neutrophil/lymphocyte ratio (dNLR), neutrophil/lymphocyteplatelet ratio (NLPR), aggregate index of systemic inflammation (AISI), systemic inflammation response index (SIR-I), and systemic inflammation index (SII) are well-expressed inflammatory indices that have been used to predict the severity and mortality of various inflammatory diseases. This study aimed to investigate the role of systemic inflammatory markers in predicting mortality in non-elderly and elderly COVID-19 patients.

Methods: In a retrospective study, laboratory parameters were examined for 1,792 COVID-19 patients (elderly = 710 and non-elderly = 1,082).

Article Synopsis
  • The study aimed to evaluate the antimicrobial resistance patterns of various serotypes, focusing on fluoroquinolone-resistant strains, from clinical samples in Iran.
  • A thorough electronic search led to the selection of 46 relevant articles from over 13,000 studies published between 1983 and July 2019.
  • Results indicated a 2.9% resistance to ciprofloxacin and 48.1% to nalidixic acid, with significant resistance also observed against other antibiotics, but ciprofloxacin and carbapenems remained effective against multi-drug resistant strains.
