Nosocomial infection caused by Acinetobacter baumannii has emerged as a serious problem world-wide. Finding the suitable drug is an important priority. The aim of this study was to determine colistin (polymyxin E) resistance in clinical isolates of A. baumannii from intensive care units (ICUs) of Al Zahra Hospital. ⋯ As the frequency of resistance to colistin is low, it can be used as an easily available drug for treatment of MDR A. baumannii strains, which are susceptible to colistin.

Serum uric acid level and its association with cardiometabolic risk factors in prediabetic subjects.
Excess serum uric acid (UA) accumulation can lead to various diseases. Increasing evidences reveal that UA may have a key role in the pathogenesis of metabolic syndrome. Little is known about the associations of UA levels with cardiometabolic risk factors in prediabetic individuals. This study was designed to evaluate the association between UA and cardiometabolic risk factors in prediabetic subjects with family history of diabetes compared with those with normal glucose tolerance (NGT). ⋯ High UA level was associated with some cardiometabolic risk factors in prediabetic individuals compared with normal person. UA level was also a significant predictor for prediabetes condition.

Ventilator-associated pneumonia (VAP) is a common nosocomial infection in critically ill patients with high morbidity and mortality rates. The etiology of VAP is usually bacterial. Opportunistic fungi such as Candida and Aspergillus species (spp.) are found frequently in the respiratory track secretions of immunocompetent critically ill patients known as colonization. Contribution of fungi colonization to severe bacterial VAP and poor prognosis of these patients has been documented in several studies. The aim of this study was to detect Candida spp. and Aspergillus fumigatus colonization in patients with a clinical diagnosis of VAP as a marker of high risk pneumonia. ⋯ High rate of A. fumigatus colonization in our ICU patients indicates that underlying causes such as unfavorable ICU conditions and other patient related factors such as unnecessary antibiotic therapy should be further evaluated.

Systematic review and meta-analysis on the age-specific seroprevalence of hepatitis A in Iran.
Hepatitis A virus (HAV) is a major cause of acute viral hepatitis worldwide. Annual medical and work loss costs of hepatitis A are significant even in low-endemic countries. It is recommended that each country should collect and review the information needed to estimate its national burden of hepatitis A to provide evidence for health policy makers to implement appropriate and cost-effective preventive strategy for HAV infection. The objective of this study was to estimate accurate prevalence of HAV infection in Iran for best preventive measures. ⋯ HAV infection in Iran may be considered as low or very low. Therefore, targeted vaccination of high-risk groups and more improvement in environmental sanitation would be the best preventive measure.

Detection of latent tuberculosis infection (LTBI) in transplant candidates is very important. The tuberculin skin test (TST) and interferon-gamma release assays (IGRAs) are standard immunologic tools for LTBI detection. The aim of this study was to compare the TST results and T-SPOT(®).TB test (a type of IGRAs) in kidney transplant candidates for the screening of LTBI and follow the patients with positive test for an activation of tuberculosis (TB) after transplantation and using anti-TB prophylaxis. ⋯ In kidney transplant candidates both TST and T-SPOT(®).TB test were comparable for the diagnosis of LTBI with reasonable agreement between the tests. However, further studies are needed to determine the ability of T-SPOT(®).TB test to detect LTBI and to evaluate the need for prophylaxis in these patients.
