It is unclear which anthropometric obesity indicator best predicts adverse health outcomes. This study aimed to investigate the association of body mass index (BMI), waist circumference (WC), waist-to-height ratio (WHtR), waist-to-hip ratio (WHR), and hip-adjusted WC with all-cause and cardiovascular mortality. ⋯ Indicators of visceral adiposity (e.g., hip-adjusted WC) were much stronger predictors of overall and cardiovascular mortality than were indicators of general adiposity (e.g., BMI). The full-strength effect of visceral adiposity becomes apparent only when both WC, as a risk factor, and hip circumference, as a protective factor, are individually and simultaneously taken into consideration.

Gastrointestinal (GI) cancers are common types of cancers. Among different factors that affect the etiology of GI cancers, diet has an important contribution. Dietary antioxidants decrease oxidative stress which plays a pivotal role in carcinogenesis. Several studies assessed the relation between dietary total antioxidant capacity (TAC) and risk of GI cancers. Dietary TAC was measured by three indices including FRAP (ferric ion reducing antioxidant power), TRAP (total radical-trapping antioxidant parameter), and TEAC (trolox equivalent antioxidant capacity). We performed a systematic review and meta-analysis of published studies to determine the association between dietary TAC and GI cancers risk. ⋯ This study indicated that dietary TAC significantly decreased the risk of GI cancers. Nevertheless, further prospective studies are required to clarify the association between dietary TAC and risk of GI cancers.

Multicenter Study
National Trauma Registry of Iran: A Pilot Phase at a Major Trauma Center in Tehran.
The main objective was to describe the results of the pilot phase of the national trauma registry of Iran (NTRI) at a referral university trauma center in Tehran. ⋯ After successful implementation of NTRI at a major trauma center in Tehran, RTC was identified as the main cause of admission. Most patients were young men. The mean time interval between injury occurrence and hospital admission was too long. These findings could be used to improve quality of trauma care and formulate targeted preventive strategies.

Evans syndrome is a rare syndrome associated with the simultaneous or sequential development of autoimmune hemolytic anemia (AIHA) and idiopathic thrombocytopenic purpura (ITP). Furthermore, acute kidney injury (AKI) is a syndrome characterized by the rapid loss of kidney excretory function and is most often secondary to extrarenal events. However, AKI has rarely been recorded in Evans syndrome without systemic autoimmune disease and malignant tumors of the blood and lymphatic system. ⋯ Treatment with antibiotics, rehydration therapy, and hemodialysis resulted in partial remission; thus, we diagnosed the patient with Evans syndrome presenting with AKI. The patient was successfully treated by the addition of steroid treatment. When AKI presents with hemolysis and thrombocytopenia, physicians should consider Evans syndrome, which can be appropriately treated when detected early.

Historical Article
A Biographical History of Some Iranian Pioneers in Medical Immunology and Allergy.
The oldest literature that mentioned the immunity was related to the plague of Athens in 430 BC. The germ theory had more influence on the description of the discrimination between self and non-self which is the core concept of immunology. Allergic diseases were known from 2,000 years ago while Rhazes wrote the first medical monograph about seasonal allergic rhinitis. ⋯ Mohammad Ali Maleki established the first Iranian Society of Allergy and then Prof. Abolhassan Farhoodi found the first Department of Clinical Immunology and Allergy at Tehran University. In this paper, we review the role of famous Iranian scientists and physicians in the progress of modern immunology and allergy from a historical perspective.
