RESUMEN
Few cases of B-cell acute lymphoblastic leukemia (B-ALL)-eosinophilia (ALL-eo) association have been reported. The lack or absence of blasts in the peripheral blood smear (PBS) along with urticarial rash, fever, arthralgia, myalgia, sweating, and dyspnea are common features of this condition. Herein, we report a 16-year-old male patient admitted to the emergency department with urticaria and generalized itching. PBS was examined, and eosinophils (90%) were seen in different fields. However, blast cells were not seen in PBS. In a bone marrow examination, terminal deoxynucleotidyl transferase-positive and CD20-positive lymphoid blasts were reported along with eosinophilia. Eventually, the B-ALL diagnosis was confirmed for the patient, and he was started on the Berlin-Frankfurt-Münster chemotherapy regimen. The association of B-ALL with hypereosinophilia is a rare condition. We hope this case report and literature review can help clinicians to manage this rare condition properly.
RESUMEN
BACKGROUND: Capecitabine (CAPE), an antimetabolite chemotherapy, can induce hepatic and renal toxicity. Melatonin (MEL), a neurohormone, possesses antioxidant, anti-apoptotic and anti-inflammatory effects. This study investigated the impact of MEL on capecitabine-induced hepatic and renal toxicity. METHODS AND MATERIALS: Twenty-five male Wistar rats were categorized into five groups for the study. The groups included a control group, MEL10 group (rats receiving daily intraperitoneal injections of 5 mg/kg MEL), CAPE 500 group (rats receiving weekly intraperitoneal injections of 500 mg/kg CAPE), CAPE + MEL five group, and CAPE + MEL 10 group. All groups were treated for a duration of 6 weeks. Various hematological, serological, biochemical, and histopathological assessments were conducted to evaluate the objective of the study. RESULTS: The administration of CAPE led to significant liver and kidney toxicity, as evidenced by elevated levels of malondialdehyde (MDA), myeloperoxidase (MPO), nitric oxide (NO), as well as serological markers including AST, ALT, ALP, BUN, and creatinine. CAPE exposure also resulted in a reduction in total antioxidant capacity (TAC) and glutathione peroxidase (GPx) levels. Histological examination revealed hyperemia in both liver and kidney tissues exposed to CAPE. However, treatment with MEL demonstrated positive effects. MEL administration alleviated oxidative stress, reduced levels of liver enzymes, BUN, and creatinine, and ameliorated histopathological degenerations. MEL also increased GPx and TAC levels. Moreover, MEL treatment aided in restoring the body weight that was lost due to CAPE exposure. CONCLUSION: Our findings indicated that the administration of MEL in rats significantly enhanced the hepatic and renal toxicity induced by CAPE.

Cell-mediated immunity (CMI) is crucial in controlling the highly aggressive and progressive SARS-CoV-2 infection. Despite extensive researches on severe COVID-19 infection, the etiology and/or mechanisms of lymphopenia, decreased T cell-mediated responses in patients, cytokine release storms (CRS), and enhanced pro-inflammatory mediators are not fully understood. Several T cell subpopulations, including innate-like lymphocytes (ILLs) and conventional T cells, are involved in COVID-19 infection; however, their contribution to immunity and complications remains to be more elucidated. CD16+ T cells are among the effective players in the development of T helper1 (Th1) responses in COVID-19 infection, while their robust cytolytic properties contribute to lung tissue damage. While CD56-CD16bright NK cells play a protective role, natural killer T (NKT) cells, mucosal-associated invariant T (MAIT) cells, and γδ T cells and their roles in COVID-19 require further investigation. The involvement of the other T cell subsets, such as Th17, along with neutrophils, adds to the complexity of the situation. In this review, we presented and discussed the findings of recent studies on T cell responses and the contribution of each type of immune cells to COVID-19.

PURPOSE: Fear of progression or recurrence is assumed as a rational response to the threat of cancers and types of cancer treatment. However, the elevated levels of fear in cancer patients can become dysfunctional. Therefore, a valid and reliable questionnaire is unquestionably required for this purpose. This study aimed to translate the Fear of Progression Questionnaire and evaluate its psychometric properties for patients with gastrointestinal cancers in Iran. METHODS: In this study with a methodological research design, a total number of 430 patients affected with gastrointestinal cancers referring to Northern Iran completed the 43-item Fear of Progression Questionnaire. The psychometric properties of the questionnaire were evaluated, including the face validity and content validity. Then construct validity was assessed using exploratory and confirmatory factor analyses. Finally, the reliability was assessed using internal consistency (Cronbach's alpha) and stability (intraclass correlation coefficient). RESULTS: Based on the result of the face and content validity, no items were revised and removed. The five extracted factors included were emotional response, employment, and loss of independence, economy/family, and coping. These factors explained 37% of the total variance of Fear of Progression Questionnaire. Reliability (by Cronbach's alpha) and stability (test retest was evaluated by intraclass correlation coefficient) were more than 0.7. CONCLUSION: The study results revealed that the Persian version of the Fear of Progression Questionnaire had acceptable reliability and validity for cancer patients in Iran. Emotional responses explained the most variance of the concept of fear of progression among cancer patients.

The coronavirus disease 2019 (COVID-19) pandemic is spreading rapidly, and its psychosocial impact remains a big challenge. In this respect, quarantine has been recommended, as a significant practice, to prevent the given condition. Therefore, the present study was to determine the prevalence rates of depression, anxiety, and stress and to reflect on the impact of COVID-19, as a traumatic stressor event, on individuals. This web-based survey was fulfilled via an online questionnaire, completed by respondents selected through the cluster sampling technique, from March 24 to April 10, 2020, living in Mazandaran Province, Northern Iran. Accordingly, the data regarding demographic characteristics, physical health status, quarantine compliance, contact with COVID-19, and additional information were collected. The psychosocial impact of the pandemic was then assessed by the Impact of Event Scale-Revised (IES-R), and the respondents' mental health status was evaluated using the Depression, Anxiety, and Stress Scale-21 (DASS-21). Data analysis was further performed by linear regression. The study findings, from 1075 respondents, revealed that 22.5% of the cases had moderate-to-severe depression, 38.5% of the individuals were suffering from moderate-to-severe anxiety, and 47.2% of the participants were experiencing moderate-to-severe stress. In 14.5% of the respondents, the psychosocial impact of COVID-19 also varied from the possibility of post-traumatic stress disorder (PTSD) to immunosuppression (p < 0.01). With the high prevalence rates of depression, anxiety, and stress, mental health professionals are suggested to develop psychosocial interventions and support plans for the general population to reduce the impact of the COVID-19 pandemic on public mental health status.
RESUMEN
Background: Severe side effects after vaccination with coronavirus disease 2019 (COVID-19) vaccines are rare but can be fatal. To date, vaccine-induced immune thrombotic thrombocytopenia (VITT) cases have been reported after injection of mRNA and adenoviral vectors COVID-19 vaccines. Here, we report the second suspected case of VITT after vaccination with the Sinopharm vaccine, an inactive vaccine. Key Clinical Question: The Key Clinical Question was to determine whether inactivated COVID-19 vaccines could induce VITT and how to diagnose and treat such cases. Clinical Approach and Conclusions: Our patient developed deteriorating symptoms the day after vaccination and was admitted to the emergency department on day 5 after vaccination. After performing laboratory analysis, thrombosis with thrombocytopenia was suggested, further confirmed by highly positive anti-heparin-platelet factor 4 antibodies assay and color Doppler ultrasonography. He was then treated with high-dose intravenous immunoglobulin, corticosteroid, and nonheparin anticoagulant.
RESUMEN
BACKGROUND: The presence of maternal emotions towards the offspring resulting from assisted reproductive techniques (ART) has been previously reported in oocyte donors. However, there is limited information about the presence of these emotions in oocyte donors during the ART process and before pregnancy. The aim of this study was to evaluate the emotions of oocyte donor women towards the potential genetic offspring and to compare them with women treated with ART by using own oocytes. METHODS: A cross-sectional study was conducted on 100 women who were divided into two groups of oocyte donors and those treated with ART and using autologous oocyte. At the time of oocyte retrieval. Using a validated questionnaire, the emotions toward potential offspring (EPO) resulting from ART and its three dimensions (including imagination, sense of ownership, and importance of treatment outcome) were measured and compared in two groups. RESULTS: Comparison of the EPO in the two groups showed that the emotions in all three dimensions were lower in oocyte donors than the other group (p < 0.001). Moreover, in oocyte donors, the mean score of the scale of the importance of treatment outcome dimension was higher than the other two scales (p < 0.001). CONCLUSION: The results of the study showed that there is a significant emotion toward the potential offspring in oocyte donors. The presence of these emotions thus should be considered in formulating the ethical charter of ART by using oocyte donation.

The purpose of this study was designing and synthesizing a PLGA formulation targeted with anti-CD40 monoclonal antibody, which has suitable physicochemical properties as a dimethyl fumarate (DMF) drug delivery system having minimal cytotoxicity. Therefore, this research was performed to determine the effect of anti-CD40mAb-DMF-NPs on the expression of IL-1ß, IL-6 and TNF-α cytokine genes in mouse splenocytes. The toxicity of different groups, namely free PLGA, free DMF, DMF-containing PLGA, anti-CD40mAb-DMF-NPs, was evaluated by MTT assay. PLGA formulations conjugated with mAbCD40 were loaded with DMF drug that showed little cytotoxic effect against mouse splenocytes. QRT-PCR method was subsequently used to assess the effect of the mentioned groups on the expression of IL-1ß, TNF-α and IL-6 genes. After treatment of the cells with DMF alone or with polymer carriers, the expression of IL-1ß, IL-6 and TNF-α cytokine genes was significantly reduced. The decrease in expression was markedly higher in the antibody-targeted nanoparticles group relative to other treatment groups. Our results in this area are promising and provide a good basis for further future studies in this regard.

BACKGROUND: Human immunodeficiency virus (HIV) transmission pattern in Iran has been changed from injection drug to sexual contact. Lack of accurate assessment of HIV in people with sexually transmitted diseases (STDs) in Iran prompted us to conduct this study to determine the frequency of HIV infection in these patients. MATERIALS AND METHODS: In this cross-sectional study which conducted in 2016-2017, overall, 190 patients with STDs referring to two hospitals of Hamadan were enrolled in the study. All of the patients were examined for HIV in the first visit by rapid test and then 1 and 4 months later by the 4th generation ELISA. A questionnaire including demographic data, clinical manifestations, and high-risk behaviors was completed for all of the referring people. The collected data were analyzed using appropriate statistical tests. RESULTS: Of 190 patients, 126 (66.3%) were female with a mean age of 34.1 ± 10.1 years and 64 (33.7%) were male with a mean age of 30.8 ± 7.8 years. One hundred twenty-eight (67.4%) got married, 73 (38.4%) and 76 (40%) had a diploma and postgraduate education, respectively, 32 (16.8%) mentioned the history of unsafe sex, and 23 (12.1%) had used condoms continuously during sexual contacts. The most common STDs were reported genital warts, 107 patients (56.3%), vaginal discharge (28, 14.7%), and genital ulcer (33, 17.4%). Two (1%) patients were positive for HIV at the first visit. CONCLUSION: Patients with STDs should be considered as an important source of HIV transmission, so clinicians should pay more attention to screening these patients for HIV infection.
