Evaluating the effect of grape syrup on iron deficiency anemia in women: A randomized clinical trial.

Globally, iron deficiency reigns as the most prevalent nutritional disorder, with anemia disproportionately impacting women of childbearing age. Despite the effectiveness of existing treatments, like iron supplements, their side effects remain a concern. This study explores the potential of grape syrup (GS), a functional iron-rich food, to modulate markers of iron-deficient anemia in women. A randomized, double-blind study explored the impact of GS on iron deficiency anemia markers in 130 women. Participants were allocated to intervention or placebo groups. For 4 weeks, the intervention group received a daily 50 mg ferrous sulfate tablet alongside 10 cc of GS thrice daily. The placebo group received a 50 mg ferrous sulfate tablet with a 10 cc placebo syrup thrice daily. Before and after the intervention, key markers like red blood cell count (RBC), mean corpuscular volume (MCV), hemoglobin (Hb), hematocrit (Hct), ferritin, total iron binding capacity (TIBC), and serum iron were assessed. Notably, both Hb and Hct levels were significantly higher in the GS group (p < .05). Additionally, RBC and MCV values showed significant improvement compared to the placebo group (p < .05). However, no significant difference was observed for other iron deficiency markers like serum iron, ferritin, and TIBC (p > .05). This study's findings suggest that combining grape syrup with iron tablets might offer potential advantages over iron tablets alone in managing iron deficiency anemia.

Endocarditis Caused by Coxiella burnetii: A Case Report in Western Iran.

Background: Q fever is a contagious zoonotic disease which is caused by a gram-negative and intracellular Coccobacillus known as Coxiella burnetii ticks play a role in its transmission. Endocarditis is the most common consequence of chronic Q fever. Methods: Here we report a case of endocarditis caused by Q fever. The patient is a 67-year-old, and she had coronary artery bypass graft (CABG) and aortic valve replacement surgery. Results: The result of echocardiography showed a suspicious mass (Vegetation) on the implanted valve. Based on laboratory and clinical assessments, endocarditis caused by C. burnetii was the final diagnosis. Conclusion: Q fever is a tick-transmitted pathogen that has been known as an important cause of culture-negative endocarditis in Iran, and more attention needs to be paid to this disease in Iran by the healthcare system and physicians.

Stability of Neutralizing Antibody of PastoCoAd Vaccine Candidates against a Variant of Concern of SARS-CoV-2 in Animal Models.

Background: Since the beginning of the SARS-CoV-2 pandemic, there have been mutations caused by new SARS-CoV-2 variants, such as Alpha, Beta, Gamma, Delta, and Omicron, recognized as the VOC worldwide. These variants can affect vaccine efficacy, disease control, and treatment effectiveness. The present study aimed to evaluate the levels of total and neutralizing antibodies produced by PastoCoAd vaccine candidates against the VOC strains at different time points. Methods: Two vaccine candidates were employed against SARS-CoV-2 using adenoviral vectors: prime only (a mixture of rAd5-S and rAd5 RBD-N) and heterologous prime-boost (rAd5-S/SOBERANA vaccine). The immunogenicity of these vaccine candidates was assessed in mouse, rabbit, and hamster models using ELISA assay and virus neutralization antibody test. Results: The immunogenicity results indicated a significant increase in both total and neutralizing antibodies titers in the groups receiving the vaccine candidates at various time points compared to the control group (p < 0.05). The results also showed that the PastoCoAd vaccine candidates Ad5 S & RBD-N and Ad5 S/SOBERANA could neutralize the VOC strains in the animal models. Conclusion: The ability of vaccine candidate to neutralize the VOC strains in animal models by generating neutralizing antibodies at different time points may be attributed to the use of the platform based on the Adenoviral vector, the N proteins in the Ad5 S & RBD-N vaccine candidate, and the SOBERANA Plus booster in the Ad5 S/SOBERANA vaccine candidate.

Rickettsia conorii subsp. israelensis infection: a case report from southeast Iran.

BACKGROUND: Mediterranean spotted fever (MSF) is a zoonotic and vector-borne disease caused by Rickettsia conorii. We report a case (36 year-old-woman) of MSF caused by Rickettsia conorii from Iran. CASE PRESENTATION: In September 2019, the patient was admitted to the hospital in Kerman province with flu-like symptoms and maculopapular lesions. According to the laboratory results, thrombocytopenia, elevated liver enzymes, and cardiac enzymes were observed. Skin biopsy was examined for Crimean-Congo Hemorrhagic Fever (CCHF) and MSF using the Real-Time-PCR and ELISA method. Finally, the sample was positive for Rickettsia conorii subsp. israelensis and treated with doxycycline and completely recovered. CONCLUSIONS: This study showed that MSF could be present in Iran. Therefore, identifying endemic areas in Iran for this disease should be on the agenda.

Tropheryma whipplei intestinal colonization in immunocompromised children in Iran: a preliminary study.

Aim & method:Tropheryma whipplei causes Whipple's disease. Children are reservoirs of this bacterium. The aim of this study was to investigate the presence of T. whipplei in children with immunodeficiency in central Iran from July 2018 to February 2019. Stool samples were tested by SYBR Green and Taq-Man real-time PCR assays. For confirmation, the isolated DNA was sequenced. Results: One hundred and thirty children were enrolled. Acute lymphocytic leukemia was the most reported immunodeficient disease (77%), followed by non-Hodgkin lymphoma and retinoblastoma. Thirteen (10%) children had T. whipplei DNA in the stool; 11.4% of the children under 5 years old were positive. Conclusion: This is the first study showing the circulation of T. whipplei in Iran.

Oil-in-water emulsion formulated with eucalyptus leaves extract inhibit influenza virus binding and replication in vitro.

Throughout human history, the human-beings have been used different types of plants as antimicrobial agents in fight against infectious diseases. Influenza virus is one of the most common causes of respiratory infection and transmitted through direct contact with flu infected individuals and contaminated substances or droplets. In the current study, both oil-in-water and water-in-oil emulsions with hydroalcoholic extract of eucalyptus leaves (OLHE) were developed and their antiviral efficiency was evaluated. To doing so, Madin-Darbey Canine Kidney (MDCK) cells were treated with effective minimal cytotoxic concentration of the formulated emulsions. The treated cells were then infected with 50% cell culture infectious dose (100 CCID50) of the A/H1N1 virus (the swine flu). The viral titers were measured by hemagglutination (HA) and cell culture infectious dose 50% (CCID50) assays. Also, to check the virus binding inhibition via the formulated extract, the viruses were incubated with the formulated extracts. Our study showed that the oil-in-water emulsions formulated with 2% eucalyptus leaves extract inhibited virus replication completely when the cells were infected by 100 CCID50 and decreased HA titer up to four fold. Therefore, this formulation, may hold promising application to prevent influenza virus transmission through direct contact among children and passengers.

Q fever endocarditis in Iran: A case report.

In this report, we describe the first chronic case of Q fever endocarditis in a 72-year-old woman in Iran. The patient developed radiation-associated heart disease status post (s/p) coronary artery bypass surgery, mitral and aortic valve replacements, and tricuspid valve repair. Endocarditis was also suspected due to a history of heart valve surgery. Blood cultures were negative, but a diagnosis of Q fever endocarditis was confirmed based on serologic titers (IgG phase I 1:32,768). The patient was treated with doxycycline and hydroxychloroquine.
