The Prognostic Value of Thrombocytopenia in COVID-19 Patients; a Systematic Review and Meta-Analysis.

Arch Acad Emerg Med 2020 19;8(1):e75. Epub 2020 Sep 19.

Pediatric Congenital Hematologic Disorders Research Center, Shahid Beheshti University of Medical Sciences, Tehran, Iran.

Introduction: Multiple lines of evidence have attested that decreased numbers of platelets may serve as a surrogate marker for poor prognosis in a wide range of infectious diseases. Thus, to provide a well-conceptualized viewpoint demonstrating the prognostic value of thrombocytopenia in COVID-19, we performed a meta-analysis of pertinent literature.

Methods: The keywords "platelet" OR "thrombocytopenia" AND "COVID-19" OR "coronavirus 2019" OR "2019-nCoV" OR "SARS-CoV-2" were searched in National Library of Medicine Medline/PubMed and Scopus between December 30, 2019, and May 9, 2020 in English without any restriction. The initial search results were first screened by title and abstract, and then full texts of relevant articles representing information on the platelet count (main outcome) with a clinically validated definition of COVID-19 severity were finally selected. To assess the existence of bias in the included studies, the funnel plot and egger plot along with egger tests were used. Also, the heterogeneity among the included studies was tested using the Chi-square test.

Results: The results of our meta-analysis of 19 studies, totaling 3383 COVID-19 patients with 744 (21.9%) severe cases, revealed that non-severe cases have a significantly higher number of platelets and showed that the probability of the emergence of thrombocytopenia is significantly higher in the severe cases with the pooled mean difference of -21.5 (%95 CI: -31.57, -11.43).

Conclusion: Decreased number of platelets more commonly associates with severe COVID-19; however, whether the emergence of thrombocytopenia may result in diseases severity or the severity of the disease may decrease platelets, is open to debate.

The role of alimentary and biliopancreatic limb length in outcomes of Roux-en-Y gastric bypass.

Wideochir Inne Tech Maloinwazyjne 2020 Jun 16;15(2):290-297. Epub 2019 Nov 16.

Minimally Invasive Surgery Research Center, Iran University of Medical Sciences, Tehran, Iran.

Introduction: Roux-en-Y gastric bypass (RYGB) is one of the safe and easily reproducible bariatric procedures.

Aim: To evaluate the effect of biliopancreatic limb (BPL) and alimentary limb (AL) length on weight loss outcomes after RYGB.

Material And Methods: This retrospective cohort study included 313 morbidly obese patients who underwent primary laparoscopic RYGB 2009-2015. Patients' BPL and AL lengths were categorized into three groups: group 1 (BPL: 50 cm and AL: 150 cm), group 2 (BPL: 150 cm and AL: 50 cm), and group 3 (BPL: 100 cm and AL: 100 cm). Data were provided from the Iranian National Obesity Surgery Database. The generalized estimating equations method was used to assess the effect of limbs length on %excess weight loss (%EWL).

Results: Mean ± standard deviation age and body mass index (BMI) of 252 patients were 38.55 ±10.24 years and 45.8 ±4.77 kg/m, respectively. Totally, 172 (68.3%, BMI of 46 ±5 kg/m), 48 (19%, BMI of 45.12 ±4.26 kg/m), and 32 (12.7%, BMI of 45.43 ±4.23 kg/m) were in group 1, 2, and 3, respectively (p = 0.44). The results showed that the choice of different limb lengths had no significant effect on %EWL over 12 months follow-up (p = 0.625) adjusted for baseline BMI (p = 0.25). Mean %EWL in the patients with longer BPL and shorter AL was 5.43% (1.91, 8.95) higher in comparison to the patients with shorter BPL and longer AL during 36 months postoperatively adjusted for baseline BMI (p = 0.002).

Conclusions: During 12 months after RYGB, %EWL was not associated with BPL or AL length. However, during 36 months postoperatively, the patients with longer BPL had a significantly higher %EWL in comparison to the patients with shorter BPL.

Risk factors for attention-deficit/hyperactivity disorder: a case-control study in 5 to 12 years old children.

Med Pharm Rep 2020 Apr 22;93(2):175-180. Epub 2020 Apr 22.

Department of Biostatistics, School of Public Health, Iran University of Medical Sciences, Tehran, Iran.

Background And Aims: Attention deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder known by a pattern of diminished sustained attention and increased impulsivity or hyperactivity. This study aimed to evaluate the risk factors associated with ADHD.

Methods: This case-control study included 297 ADHD children aged 5-12 years admitted to Tehran Institute of Psychiatry, Iran (2012-2013). They were compared with 297 non-ADHD (as controls matched to cases 1:1) who were of the same age (±1 years) selected from outpatients in general pediatric medical centers in Tehran. ADHD Rating Scale IV (ADHD-RS-IV)-Home Version was used to confirm ADHD. Data were analyzed using conditional binary logistic regression.

Results: Mean±SD age were 8.18±3.11 and 8.11±2.9 years in the case and control groups, respectively (P=0.61). Mean±SD birth weight (BW) was higher in ADHD patients compared with the controls (3245.09±0.66 vs 3026.56±0.45 gr, P=0.045). The results showed that odds of ADHD in children with high BW (>3500g) was 3.36 (1.96-5.78) times the odds of ADHD in normal BW children (2500-3500g) controlling for other risk factors. ADHD risk in low BW children (<2500 g) was not statistically different compared with normal BW children [OR:1.74 (0.7-3.7)]. Experience of neonatal disease, fewer offspring, lower level of mothers' education, and preterm delivery were also risk factors for higher odds of ADHD.

Conclusion: Based on our sample, preterm birth, neonatal disease, high BW, lower level of mother's education, and fewer offspring were ADHD risk factors.

Bronchiolitis Obliterans Syndrome and Death in Iranian Lung Transplant Recipients: A Bayesian Competing Risks Analysis.

Tanaffos 2016 ;15(3):141-146

Lung Transplant Research Center, Masih Daneshvari Hospital, National Research Institute of Tuberculosis and Lung Disease, Tehran, Iran.

Background: Bronchiolitis obliterans syndrome (BOS) is delayed allograft deterioration after lung transplant (LTX) that is clinically characterized by ≥ 20% decline from the baseline value of forced expiratory volume during the first second (FEV1). BOS is still a major obstacle limiting long-term survival post-LTX. The main aim of this study was to determine the predictors of BOS and death in Iranian LTX recipients.

Materials And Methods: This retrospective cohort study included 44 LTX recipients who survived ≥ 3 months post-LTX at the Masih Daneshvari Hospital, Tehran, Iran from 2000 to 2014. The outcome was time from lung transplantation to BOS and/or death (due to all causes except BOS). We used competing risks analysis to assess the effect of other factors on the cumulative incidence function of BOS and death. We applied a Fine and Gray model with Bayesian approach.

Results: The recipients' age (Mean ± SD) was 36.7 ± 14.5 yr. 11 (25%) recipients developed BOS as the first event within the first five years post-LTX and 13 (30%) died due to all causes except for BOS. Our results showed that CMV infection was associated with a significant increase in risk of developing BOS [hazard ratio (HR) 1.22 (95% credible set: (1.01, 3.2)] controlling for other variables. Bilateral transplantation [HR (95% credible set): 2.4(1.51, 4.05)] and CMV infection [HR (95% credible set): 2.02 (1.67, 2.55)] were predictors of the mortality risk.

Conclusion: CMV infection was a predictor of BOS risk in the studied patients. Moreover, bilateral transplantation and CMV infection were significant predictors of mortality in the present sample. Multi-center studies with larger sample sizes are required to better study the other risk factors, and the pathophysiologic mechanisms of BOS.

Normothermic Ex Vivo Lung Perfusion in Brain-dead Donors Reduces Inflammatory Cytokines and Toll-like Receptor Expression.

Iran J Allergy Asthma Immunol 2016 Oct;15(5):340-354

Lung Transplant Research Center, National Research Institute of Tuberculosis and Lung Diseases (NRITLD), Shahid Beheshti University of Medical Sciences, Tehran, Iran AND Directors of Organ Transplantation and Special Diseases Office, Ministry of Health and Medical Education, Tehran, Iran.

Inflammatory responses and innate immunologic reactions play an important role in the respiratory system. Ex vivo lung perfusion (EVLP) is considered a novel method in the evaluation and reconditioning of donor lungs prior to transplantation. However, EVLP's effect on inflammatory and metabolic markers of human lung tissue is unknown.  This study investigated how the performance of EVLP on brain-dead (BD) donor lungs affects the production and release of inflammatory cytokines (IL-6, IL-8, and TNF-a), inflammatory cells and toll-like receptors (TLR) -2, 4. This study was conducted with an animal subject for qualification of EVLP team and then EVLP was performed on 4 human cases referred to Masih Daneshvari Hospital (Tehran,Iran), from May 2013 to July 2015. Two of these cases, who had acceptable lung function parameters, were enrolled in this study for immunologic investigations. Bronchoalveolar lavages (BAL) were taken before and after EVLP. Cytokines were quantitatively measured before lung retrieval, at the end of the lung removal, at the start of EVLP, and at the end of the each hour of EVLP. TLR expression was measured on the cells obtained by flow cytometry. TNF-a, IL-6 and IL-8 decreased in each stage of washing perfusate in both cases, and the level of cytokines in serum was in the normal range. Flow cytometry analysis revealed a decreasing expression of CD3, CD4/8, CD19, and CD16+56, as well as TLR-2 and TLR-4 in both cases. Intra-capillary pools of pro-inflammatory cytokines (IL-6, IL-8, and TNF-a) were determined to contribute to the lung injury during prolonged lung perfusion. This raises the possibility that EVLP donor lungs could be less immunogenic than standard lungs. However, to assess EVLP's effects on lung grafts and optimize recipient outcomes, further studies with a sufficient number of lungs are required.

Ex Vivo Lung Perfusion: Establishment and Operationalization in Iran.

Exp Clin Transplant 2017 Feb 14;15(1):82-88. Epub 2016 Oct 14.

From the Lung Transplant Research Center, National Research Institute of Tuberculosis and Lung Disease (NRITLD), Shahid Beheshti University of Medical Sciences, Tehran, Iran.

Objectives: Although the number of lung transplants is limited because of general shortage of organ donors, ex vivo lung perfusion is a novel method with 2 main benefits, including better evaluation of lung potential and recovery of injured lungs. The main aim of this study was to establish and operationalize ex vivo lung perfusion as the first experience in Iran.

Materials And Methods: This was a prospective operational research study on 5 cases, including 1 pig from Vienna Medical University and 4 patients from Masih Daneshvari Hospital. All organ donations from brain dead donors were evaluated according to lung transplant or ex vivo lung perfusion criteria from May 2013 to July 2015 in Tehran, Iran. If a donor did not have any sign of severe chest trauma or pneumonia but had poor oxygenation due to possible atelectasis or neurogenic pulmonary edema, their lungs were included for ex vivo lung perfusion.

Results: A successful trend in the difference between the pulmonary arterial Po2 and the left atrial Po2 was observed, as well as an increasing pattern in other functional parameters, including dynamic lung compliance and a decreasing trend in pulmonary vascular resistance.

Conclusions: These initial trials indicate that ex vivo lung perfusion can lead to remarkable progress in lung transplant in Iran. They also provide several important pieces of guidance for successful ex vivo lung perfusion, including the necessity of following standard lung retrieval procedures and monitoring temperature and pressure precisely. The development of novel methods can provide opportunities for further research studies on lungs of deceased donors and lead to undiscovered findings. By keeping this science up to date in Iran and developing such new and creative methods, we can reveal effective strategies to promote the quality of donor lungs to support patients on transplant wait lists.

Risk factors associated with survival after lung transplant in iran.

Exp Clin Transplant 2014 Aug 19;12(4):290-4. Epub 2014 May 19.

From the Department of Biostatistics, Faculty of Medical Sciences, Tarbiat Modares University, Tehran, Iran.

Objectives: Limited information is available about risk factors associated with survival after lung transplant in Iranian recipients. This study evaluated the effect of recipient and donor characteristics on survival after lung transplant.

Materials And Methods: This retrospective study included 69 lung transplants (single, 31 patients [45%]; bilateral, 38 patients [55%]), from 2000 to 2013, at the National Research Institute of Tuberculosis and Lung Diseases, Masih Daneshvari Hospital, Shahid Beheshti University of Medical Sciences, Tehran, Iran. The Kaplan-Meier method was used to calculate survival, and variables were evaluated with multivariate analysis.

Results: There were 54 male recipients (78%), and the most frequent indications for transplant included pulmonary fibrosis in 31 patients (45%) and bronchiectasis in 23 patients (33%). Recipient mean age was 36 ± 13 years and body mass index was 20 ± 4 kg/m2. Mean half-life (all recipients) was 2 ± 1 years and survival was 73% at 1 month, 67% at 1 year, and 40% at 5 years after transplant. For recipients who survived > 2 weeks after transplant half-life and survival were similar to previously international reported results. Recipient age, sex, type of transplant, body mass index, and pulmonary artery pressure were not associated with survival. Survival was significantly higher with recipient bronchiectasis, younger donors, and female donors.

Conclusions: Survival after lung transplant was better with recipients who had bronchiectasis and donors that were younger or female. Patient selection, invasive monitoring, and supportive techniques such as extracorporeal membrane oxygenation for unstable patients during surgery may be helpful.

Effect of lavender inhalation on the symptoms of primary dysmenorrhea and the amount of menstrual bleeding: A randomized clinical trial.

Complement Ther Med 2014 Apr 6;22(2):212-9. Epub 2014 Jan 6.

Research Development Unit, Barij Essence Pharmaceutical Company, Kashan, Iran.

Objective: The purpose of this study was to explore the effect of Lavandula angustifolia (lavender) inhalation on the symptoms of dysmenorrhea and the amount of menstrual bleeding in female students with primary dysmenorrhea.

Design: This study is an experimental clinical trial. The subjects were 96 female students residing in dormitory at Tehran University of Medical Sciences in 2011 and suffering from level two or three dysmenorrhea according to the verbal multi-dimensional scoring system. The inclusion criteria were as: being single, suffering from primary dysmenorrhea, having no genital organs disorder, having no systemic disease, having regular menstrual cycles, using no contraceptives, etc. The follow-up time was 4 menstrual cycles.

Interventions: The subjects were randomized into two groups: experimental (n=48) who inhaled lavender based on sesame oil, and placebo (n=48) who inhaled sesame oil only.

Main Outcome Measures: The severity of dysmenorrhea symptoms was measured through a questionnaire, and the amount of menstrual bleeding was measured by sanitary towel usage.

Methods: Ordinal logistic regression and generalized estimating equation (GEE) were used to analyze the data.

Results: The symptoms of dysmenorrhea were significantly lowered in the lavender group compared to the placebo group (p<0.001). The amount of menstrual bleeding in the lavender group was reduced in comparison to the placebo group but the difference was not statistically significant (p=0.25). No significant difference was observed for blood clot among the students (p=0.666).

Conclusions: This study showed that lavender inhalation was effective in alleviating dysmenorrhea symptoms, suggesting that it could be applied by midwives in a safe manner because of no side effects, simplicity and cost-effectiveness for all patients.
