Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Zataria multiflora is employed as an antitussive, anti-spasmodic, analgesic and etc. Agent in traditional medicine. The modern medical studies are also confirmed effects of this plant for treatment of respiratory problems via anti-inflammatory, anti-oxidant and immunomodulatory properties. AIM OF STUDY We evaluated efficacy of Z. multiflora on tests of pulmonary function, respiratory symptoms, inhaled bronchodilator drugs use, and hematological factors in COPD patients. METHODS Patients (n = 45) were randomly grouped in the following three groups: placebo group (P), groups received Z. multiflora extract 3 and 6 mg/kg/day (Z3 and Z6). FEV1 and MEF25-75, respiratory symptoms, inhaled bronchodilator drugs use and hematological factors were evaluated before and 1-2 months after treatment. RESULTS Z. multiflora led to significant enhancement of FEV1 (p < 0.05 to p < 0.01). Respiratory symptoms were also considerably ameliorated following treatment with extracts for 1 and 2 months compared to baseline values (p < 0.05 to p < 0.001). In groups received extract, inhaled bronchodilator drugs use was remarkably declined at the end of study (both, p < 0.05). Reduction of total WBC was observed 1-2 months after treatment in treated groups with extract compared to baseline values (p < 0.05 to p < 0.001). Neutrophils were remarkably declined in Z3 and Z6 groups after 2-monthes compared to 1-month treatment (p < 0.05 to p < 0.01). CONCLUSION The evidence show therapeutic effect of this herb on COPD patients which could be result from properties that help to decrease inflammation.

Abstract
AIMS We aimed to build radiomic models for classifying non-small cell lung cancer (NSCLC) histopathological subtypes through a dual-centre dataset and comprehensively evaluate the effect of ComBat harmonisation on the performance of single- and multimodality radiomic models. MATERIALS AND METHODS A public dataset of NSCLC patients from two independent centres was used. Two image fusion methods, namely guided filtering-based fusion and image fusion based on visual saliency map and weighted least square optimisation, were used. Radiomic features were extracted from each scan, including first-order, texture and moment-invariant features. Subsequently, ComBat harmonisation was applied to the extracted features from computed tomography (CT), positron emission tomography (PET) and fused images to correct the centre effect. For feature selection, least absolute shrinkage and selection operator (Lasso) and recursive feature elimination (RFE) were investigated. For machine learning, logistic regression (LR), support vector machine (SVM) and AdaBoost were evaluated for classifying NSCLC subtypes. Training and evaluation of the models were carried out in a robust framework to offset plausible errors and performance was reported using area under the curve, balanced accuracy, sensitivity and specificity before and after harmonisation. N-way ANOVA was used to assess the effect of different factors on the performance of the models. RESULTS Support vector machine fed with selected features by recursive feature elimination from a harmonised PET feature set achieved the highest performance (area under the curve = 0.82) in classifying NSCLC histopathological subtypes. Although the performance of the models did not significantly improve for CT images after harmonisation, the performance of PET and guided filtering-based fusion feature signatures significantly improved for almost all models. Although the selection of the image modality and feature selection methods was effective on the performance of the model (ANOVA P-values <0.001), machine learning and harmonisation did not change the performance significantly (ANOVA P-values = 0.839 and 0.292, respectively). CONCLUSION This study confirmed the potential of radiomic analysis on PET, CT and hybrid images for histopathological classification of NSCLC subtypes.

Abstract
Background and Aims The effects of high-protein diets on regulating sleep have received research attention in recent decades. However, no studies have examined the effects of these diets in obese adults. Therefore, this study was conducted to investigate the effects of low-calorie high protein diets on sleep quality in obese adults. Methods This study is a randomized clinical trial conducted on 60 obese adults (BMI > 29.9 kg/m2) diagnosed with low-quality sleep. All participants were given a diet with a 750-calorie energy deficit. While the control group was given a normal diet, the intervention group received a diet with 30% more protein. Results The results showed a significant difference between the control group and intervention group with respect to sleep apnea at 30-, 60-, and 90-day follow-up (p < 0.01). Sleep quality, apnea-hypopnea index (AHI), sleep latency (SL), and polysomnography were significantly different between the two groups (p < 0.05), showing an improvement in sleep quality and obstructive sleep apnea in the intervention group (p < 0.05). Conclusion This study shows that low-calorie high-protein diets can effectively improve apnea, sleep quality, and body composition indices in obese adults.

Abstract
INTRODUCTION The last decade has seen the increased prevalence of obesity as a public health challenge, particularly in low- and middle-income countries. At the same time, studies have shown that there is a two-way relationship between low-calorie diets and depression in obese individuals. This study was designed and implemented to investigate the effect of a low-calorie high-protein diet on psychometric variables in obese individuals. MATERIALS AND METHODS The present study is a Randomized Clinical Trial. Individuals meeting the inclusion criteria were randomly assigned to either the intervention group (low-calorie diet with increased protein percentage) or the control group (standard protein percentage) using block stratification. Psychometric characteristics of the participants were evaluated using the DASS-21 questionnaire. RESULTS There were no significant differences in enrollment between the two groups with respect to anthropometric variables, body composition, and physical activity (p-value > .05). Similarly, no significant differences were observed between the two groups in terms of psychological variables (depression, anxiety and stress) (p-value > .05). However, the intervention groups had significantly lower depression and anxiety scores 15 days into the intervention (p-value < .05). After 30 and 60 days of intervention, significant differences were observed between the 2 groups in terms of depression, stress, and anxiety (p-value < .05), indicating a relative improvement in psychometric variables in the intervention group (p-value < .05). CONCLUSION The results of this study showed that low-calorie diets with a high-protein percentage can significantly improve psychometric variables in obese people.Trial registration: Iranian Registry of Clinical Trials identifier: IRCT20221101056371N1..

Abstract
Lesions in the human anterior cruciate ligament (ACL) are frequent, unsolved clinical issues due to the limited self-healing ability of the ACL and lack of treatments supporting full, durable ACL repair. Gene therapy guided through the use of biomaterials may steadily activate the processes of repair in sites of ACL injury. The goal of the present study was to test the hypothesis that functionalized poly(sodium styrene sulfonate)-grafted poly(ε-caprolactone) (pNaSS-grafted PCL) films can effectively deliver recombinant adeno-associated virus (rAAV) vectors as a means of overexpressing two reparative factors (transforming growth factor beta-TGF-β and basic fibroblast growth factor-FGF-2) in primary human ACL fibroblasts. Effective, durable rAAV reporter red fluorescent protein and candidate TGF-β and FGF-2 gene overexpression was achieved in the cells for at least 21 days, especially when pNaSS-grafted PCL films were used versus control conditions, such as ungrafted films and systems lacking vectors or films (between 1.8- and 5.2-fold differences), showing interactive regulation of growth factor production. The expression of TGF-β and FGF-2 from rAAV via PCL films safely enhanced extracellular matrix depositions of type-I/-III collagen, proteoglycans/decorin, and tenascin-C (between 1.4- and 4.5-fold differences) in the cells over time with increased levels of expression of the specific transcription factors Mohawk and scleraxis (between 1.7- and 3.7-fold differences) and without the activation of the inflammatory mediators IL-1β and TNF-α, most particularly with pNaSS-grafted PCL films relative to the controls. This work shows the value of combining rAAV gene therapy with functionalized PCL films to enhance ACL repair.

Abstract
In this paper, a new dependent model is introduced. The model is motivated using the structure of series-parallel systems consisting of two series-parallel systems with a random number of parallel sub-systems that have fixed components connected in series. The dependence properties of the proposed model are studied. Two estimation methods, namely the moment method, and the maximum likelihood method are applied to estimate the parameters of the distributions of the components based on observing the system's lifetime data. A Monte Carlo simulation study is used to evaluate the performance of the estimators. Two real data sets are used to illustrate the proposed method. The results are useful for researchers and practitioners interested in analyzing bivariate data related to extreme events.

Abstract
The anterior cruciate ligament (ACL), the principal ligament for stabilization of the knee, is highly predisposed to injury in the human population. As a result of its poor intrinsic healing capacities, surgical intervention is generally necessary to repair ACL lesions, yet the outcomes are never fully satisfactory in terms of long-lasting, complete, and safe repair. Gene therapy, based on the transfer of therapeutic genetic sequences via a gene vector, is a potent tool to durably and adeptly enhance the processes of ACL repair and has been reported for its workability in various experimental models relevant to ACL injuries in vitro, in situ, and in vivo. As critical hurdles to the effective and safe translation of gene therapy for clinical applications still remain, including physiological barriers and host immune responses, biomaterial-guided gene therapy inspired by drug delivery systems has been further developed to protect and improve the classical procedures of gene transfer in the future treatment of ACL injuries in patients, as critically presented here.

Abstract
Objective To investigate the incidence of coronavirus disease 2019 (COVID-19) cases, hospitalizations and deaths in Iranians vaccinated with either AZD1222 Vaxzevria, CovIran® vaccine, SARS-CoV-2 Vaccine (Vero Cell), Inactivated (lnCoV) or Sputnik V. Methods We enrolled individuals 18 years or older receiving their first COVID-19 vaccine dose between April 2021 and January 2022 in seven Iranian cities. Participants completed weekly follow-up surveys for 17 weeks (25 weeks for AZD1222) to report their COVID-19 status and hospitalization. We used Cox regression models to assess risk factors for contracting COVID-19, hospitalization and death. Findings Of 89 783 participants enrolled, incidence rates per 1 000 000 person-days were: 528.2 (95% confidence interval, CI: 514.0-542.7) for contracting COVID-19; 55.8 (95% CI: 51.4-60.5) for hospitalization; and 4.1 (95% CI: 3.0-5.5) for death. Compared with SARS-CoV-2 Vaccine (Vero Cell), hazard ratios (HR) for contracting COVID-19 were: 0.70 (95% CI: 0.61-0.80) with AZD1222; 0.73 (95% CI: 0.62-0.86) with Sputnik V; and 0.73 (95% CI: 0.63-0.86) with CovIran®. For hospitalization and death, all vaccines provided similar protection 14 days after the second dose. History of COVID-19 protected against contracting COVID-19 again (HR: 0.76; 95% CI: 0.69-0.84). Diabetes and respiratory, cardiac and renal disease were associated with higher risks of contracting COVID-19 after vaccination. Conclusion The rates of contracting COVID-19 after vaccination were relatively high. SARS-CoV-2 Vaccine (Vero Cell) provided lower protection against COVID-19 than other vaccines. People with comorbidities had higher risks of contracting COVID-19 and hospitalization and should be prioritized for preventive interventions.

Abstract
Background Continues positive airway pressure (CPAP) therapy is a gold standard treatment for moderate to severe cases of OSA (obstructive sleep apnea). The present research aimed to describe the analysis, design, and evaluation of a telemonitoring system to improve CPAP adherence in patients afflicted with OSA.
Methods The telemonitoring system was developed in five phases. In the exploratory phase, the body of related literature was reviewed. Then a need analysis was conducted through a focus group discussion with sleep medicine specialists and sales company representatives and an interview with patients. The third phase involved data integration. Then the content and system development were done based on the previous phases. Finally, usability and functionality tests were used to evaluate the system. Results The exploratory phase and the needs analysis were conducted by four sleep medicine specialists, two medical informatics specialists, six key figures of the sales companies, two system developers, and 46 patients in different phases. Based on the results obtained from the data integration phase, the telemonitoring system involved three main parts: a patient’s application, a doctor’s portal, a selling companies’ portal (operator’s portal) along with facilitating software for patients to send the CPAP data. Usability and functionality tests were given to 7 and 10 patients, respectively. The total number of usability issues reported by users in the evaluation process was 18, with an average of 2.5 issues per user. The installation problems, disrupted links and improper playing of videos were the main functionalities problems that were solved. Conclusion The telemonitoring system, as a means of communication between patients, doctors, and selling companies, can be used to support patients clinically and technically. It has the potential to improve CPAP adherence in patients with OSA.

Abstract
Objectives Early, specific, and sensitive detection methods of COVID-19 are essential for force stopping its worldwide infection. Although CT images of the lung and/or viral RNA extraction followed by real-time reverse-transcriptase-polymerase chain reaction (rRT-PCR) are widely used; they have some limitations. Here, we developed a highly sensitive magnetic bead-based viral RNA extraction assay followed by rRT-PCR. Materials and Methods Case group included oropharyngeal/nasopharyngeal and blood samples from 30 patients diagnosed positive by PCR test for COVID-19 and control group included 30 same samples from COVID-19 negative PCR test individuals. RNA was extracted, using viral RNA extraction kit as well as using our hand-made capture bead-based technique. A one-step cDNA synthesis and Real Time PCR was conducted. A two-step comparison of the different viral RNA extraction methods for oropharyngeal/nasopharyngeal and blood samples was performed. Student t-test was applied with a P<0.05 considered statistically significant. Results In the case group, all 30 mucosal samples extracted either with viral RNA extraction kit or with beads-based assay were COVID-19 positive although in the latter category, Cqs were much lower. Although 43% of plasma samples extracted by bead-based method were found to be positive but no plasma samples extracted with column-based kit were detected positive by Real Time PCR. Conclusion Bead-based RNA extraction method can reduce RNA loss by its single-tube performance and enhance the test sensitivity. It is also more sensitive to lower viral loads as shown in the detection of blood samples and the lower Cqs of mucosal samples.

Abstract
BACKGROUND Despite the high prevalence of occupational airway disorders, they are usually underestimated by physicians. This study designed to study the prevalence of work-related symptoms (WRS) and their association with occupational exposure in outpatient pulmonary clinics. METHODS Adults with more than one year of lower respiratory symptoms were included. Retired patients, housewives and those unable to perform spirometry were excluded. Demographic, anthropometric and medical data were documented. The Persian version of National institute for health and safety respiratory questionnaire was used to classify job titles. WRS were defined as 2 (or more) positive questions with improvement of symptoms on days off work. Job exposure matrix (JEM) was used for classifying the type of occupational exposure into one of three categories: high molecular weight (HKW), low molecular weight (LMW) and mixed. RESULTS A total of 250 patients (69% male) with mean (±SD) age of 40 (±11.6) years, 178 cases of asthma and 59 chronic obstructive pulmonary disease (COPD) cases entered. Occupational exposure was seen in 51.2% of patients (26, 51 and 51 cases with HMW, LMW and mixed, respectively). WRS were lower in those who exercised regularly (24.6% vs. 39.4%) and higher in those with eczema (62.5% vs. 33.6%). Eczema had an odds ratio (OR) of 4.13 (95% CI 1.3 to 12.9, P = 0.01). Exposure to LMW almost tripled the risk of WRS (OR: 2.9, 95% CI: 1.4 to 5.9, P = 0.003) in our patients. CONCLUSION Pulmonologists are firmly advised to take their patients' occupational and vocational exposures into consideration for treatment plans, especially in those with positive history of eczema and exposure to LMW.

Abstract
Vitamin D supplementation has been shown to prevent vitamin D deficiency, but various factors can affect the response to supplementation. Data mining is a statistical method for pulling out information from large databases. We aimed to evaluate the factors influencing serum 25-hydroxyvitamin D levels in response to supplementation of vitamin D using a random forest (RF) model. Data were extracted from the survey of ultraviolet intake by nutritional approach study. Vitamin D levels were measured at baseline and at the end of study to evaluate the responsiveness. We examined the relationship between 76 potential influencing factors on vitamin D response using RF. We found several features that were highly correlated to the serum vitamin D response to supplementation by RF including anthropometric factors (body mass index [BMI], free fat mass [FFM], fat percentage, waist-to-hip ratio [WHR]), liver function tests (serum gamma-glutamyl transferase [GGT], total bilirubin, total protein), hematological parameters (mean corpuscular volume [MCV], mean corpuscular hemoglobin concentration [MCHC], hematocrit), and measurement of insulin sensitivity (homeostatic model assessment of insulin resistance). BMI, total bilirubin, FFM, and GGT were found to have a positive relationship and homeostatic model assessment for insulin resistance, MCV, MCHC, fat percentage, total protein, and WHR were found to have a negative correlation to vitamin D concentration in response to supplementation. The accuracy of RF in predicting the response was 93% compared to logistic regression, for which the accuracy was 40%, in the evaluation of the correlation of the components of the data set to serum vitamin D.

Abstract
Transient receptor potential (TRP) cation channels, which are conserved across mammals, flies, fish, sea squirts, worms, and fungi, essentially contribute to cellular Ca2+ signaling. The activity of the unique TRP channel in yeast, TRP yeast channel 1 (TRPY1), relies on the vacuolar and cytoplasmic Ca2+ concentration. However, the mechanism(s) of Ca2+-dependent regulation of TRPY1 and possible contribution(s) of Ca2+-binding proteins are yet not well understood. Our results demonstrate a Ca2+-dependent binding of yeast calmodulin (CaM) to TRPY1. TRPY1 activity was increased in the cmd1–6 yeast strain, carrying a non–Ca2+-binding CaM mutant, compared with the parent strain expressing wt CaM (Cmd1). Expression of Cmd1 in cmd1–6 yeast rescued the wt phenotype. In addition, in human embryonic kidney 293 cells, hypertonic shock-induced TRPY1-dependent Ca2+ influx and Ca2+ release were increased by the CaM antagonist ophiobolin A. We found that coexpression of mammalian CaM impeded the activity of TRPY1 by reinforcing effects of endogenous CaM. Finally, inhibition of TRPY1 by Ca2+–CaM required the cytoplasmic amino acid stretch E33–Y92. In summary, our results show that TRPY1 is under inhibitory control of Ca2+–CaM and that mammalian CaM can replace yeast CaM for this inhibition. These findings add TRPY1 to the innumerable cellular proteins, which include a variety of ion channels, that use CaM as a constitutive or dissociable Ca2+-sensing subunit, and contribute to a better understanding of the modulatory mechanisms of Ca2+–CaM.

Abstract
Background There is no pharmacological intervention on the treatment of hypoxemia and respiratory distress in COVID-19 patients. Objective The objective of the study was to study the effect of the reduced form of methylene blue (MB) on the improvement of oxygen saturation (SpO2) and respiratory rate (RR). Methods In an academic medical center, 80 hospitalized patients with severe COVID-19 were randomly assigned to receive either oral MB along with standard of care (SOC) (MB group, n = 40) or SOC only (SOC group, n=40). The primary outcomes were SpO2 and RR on the 3rd and 5th days. The secondary outcomes were hospital stay and mortality within 28 days. Results In the MB group, a significant improvement in SpO2 and RR was observed on the 3rd day (for both, p < 0.0001) and also the 5th day (for both, p < 0.0001). In the SOC group, there was no significant improvement in SpO2 (p = 0.24) and RR (p = 0.20) on the 3rd day, although there was a significant improvement of SpO2 (p = 0.002) and RR (p = 0.01) on the 5th day. In the MB group in comparison to the SOC group, the rate ratio of increased SpO2 was 13.5 and 2.1 times on the 3rd and 5th days, respectively. In the MB group compared with the SOC group, the rate ratio of RR improvement was 10.1 and 3.7 times on the 3rd and 5th days, respectively. The hospital stay was significantly shortened in the MB group (p = 0.004), and the mortality was 12.5% and 22.5% in the MB and SOC groups, respectively. Conclusions The addition of MB to the treatment protocols significantly improved SpO2 and respiratory distress in COVID-19 patients, which resulted in decreased hospital stay and mortality.

Abstract
INTRODUCTION The current study aimed at investigating the occurrence and features of olfactory dysfunction in patients with confirmed coronavirus disease 2019 (COVID-19) infection. MATERIALS AND METHODS Patients with laboratory and clinically confirmed COVID-19 infection were enrolled in this longitudinal study. They were managed in either the inpatient or outpatient setting. The demographic, clinical, and outcome data were retrieved from patients' medical records. Olfactory dysfunction features, including the onset pattern, duration, and recovery time were investigated. The visual analog scale (VAS) was utilized as a self-rating subjective measurement of olfactory function. RESULTS According to the results, the mean age of the patients (n=502) was obtained at 46.8±18.5 years; moreover, 52.4% and 47.6% of cases were female and male, respectively. It was also revealed that 35.4% and 64.5% of the subjects were outpatients and hospitalized, respectively. Based on the findings, 178 (38.4%) subjects had olfactory dysfunction. The mean values of VAS in hyposmic patients were estimated at 2.5±2.5, 8.3 ±2.1, and 9.4±1.6 at the first evaluation, in 2 weeks, and after 1 month of follow-up (P<0.001). The onset of olfactory dysfunction was more suddenly (58.7%). The majority of cases experienced olfactory dysfunction at the same time as other symptoms 72(51.1%). Based on the results, 0.4% of subjects infected with COVID-19 had olfactory dysfunction as an isolated symptom. The olfactory dysfunction was recovered after 2 weeks in 18 (25.3%) anosmic and 37(46.8%) hyposmic patients. CONCLUSION Olfactory dysfunction seemed to be an important symptom of COVID-19 infection. The occurrence of this disturbance as a transient self-limited condition was significantly higher among female subjects.

Abstract
Curcumin is proposed as a potential treatment option for coronavirus disease-19 (COVID-19) by inhibiting the virus entrance, encapsulation and replication, and modulating various cellular signaling pathways. In this open-label nonrandomized clinical trial, efficacy of nano-curcumin oral formulation has been evaluated in hospitalized patients with mild-moderate COVID-19. Forty-one patients who fulfilled the inclusion criteria were allocated to nano-curcumin (n = 21) group (Sinacurcumin soft gel, contains 40 mg curcuminoids as nanomicelles, two capsules twice a day) or control (n = 20) group, for 2 weeks. Patients' symptoms and laboratory data were assessed at baseline and during follow-up period. Most of symptoms including fever and chills, tachypnea, myalgia, and cough resolved significantly faster in curcumin group. Moreover, SaO2 was significantly higher in treatment group after 2, 4, 7, and 14 days of follow-up and lymphocyte count after 7 and 14 days. Duration of supplemental O2 use and hospitalization was also meaningfully shorter in treatment group. It is also noteworthy to mention that no patient in treatment group experienced deterioration of infection during follow-up period, but it occurred in 40% of control group. Oral curcumin nano-formulation can significantly improve recovery time in hospitalized COVID-19 patients. Further randomized placebo controlled trials with larger sample size are recommended.

Abstract
BACKGROUND Peritoneal infection following pleural empyema is not a common occurrence. Concomitant pleural empyema and peritonitis have been described in the literature mostly in immunocompromised patients with different pathogenic mechanisms and a wide array of microorganisms. Here we report a case of concomitant pleural empyema and peritonitis with an unusual microorganism in an immunocompetent host. CASE PRESENTATION The patient is a 42-year-old man with a history of 2 weeks epigastric pain who had been referred for surgical consult after failure of outpatient medical therapy. Physical examination at emergency ward revealed generalized abdominal guarding, tenderness and rebound tenderness. On emergent laparotomy, the peritoneal cavity was full of malodor pus. All abdominal viscera were intact but there was a 2x2 centimeter defect in the top of left hemi-diaphragm. Pus originated from the left thoracic cavity and then drained to the peritoneal cavity. Morganella morganii grew in the culture of aspirated pleural fluid. After abdominal lavage and chest tube drainage and receiving 14 days course of parenteral antibiotics, the patient experienced marked clinical improvement. Punctual history taking revealed a history of pneumonia before the beginning of abdominal symptoms. CONCLUSION In concomitant empyema and peritonitis in an immunocompetent patient, one should keep in mind the possibility of diaphragmatic defect and infection by unusual organisms like M. m organii.

Abstract
An appropriate diagnosis and effective treatment of sleep apnea can improve the associated quality of care and reduce morbidities. The study aims to develop and evaluate an educational intervention tailored to patients’ needs in order to increase the rate of patients’ adherence to physician's prescription for a sleep test. A multi-center, stratified, 2 parallel-arm, randomized controlled trial was conducted. The patients in the intervention group received the educational booklets on sleep apnea and sleep test which was designed based on the extracted factors through an in-depth interview with patients. All participants were contacted after two months to ask whether they completed an assessment for OSA. A total number of 1,650 individuals were screened. Finally, 104 participants were randomized to the control group (n = 50) or intervention group (n = 45) that did not differ significantly in baseline characteristics. The results of the intention to treat analysis indicate that patients in the intervention group were significantly more adherent to attend a sleep assessment for their OSA risk (30%; n = 15/50) than the patients in the control group (11.1%; n = 5/45, P <0.05). Age, history of diabetes, and the educational intervention were effective in performing the sleep test. Time limitations, Condition improvement, and high cost of diagnostic test were the most barriers, respectively. The intervention was successful in improving the adherence rate of patients to prescribed sleep test. However, the adherence rate to sleep study testing is still far from desirable and requires more complex interventions.

Abstract
Background: Panic of the disease and the associated concerns can lower the quality of life and physical performance. As long as the COVID-19 pandemic is ever on the rise, the psychological pandemic of the disease is on the rise, too. The high prevalence of COVID-19 has further increased physicians' work pressure. Patients' needs are not met adequately by physicians. It seems essential to use aids to monitor patients' needs and serve them properly. Thus, in the present research, suggestions are made on how to evaluate patients' physical and psychological conditions during the treatment via a mobile application. Methods and Analysis: The present research is a randomized, two parallel-group, controlled trial. One-hundred-twelve inpatients diagnosed with the coronavirus will be assigned randomly to the control and intervention groups. In the intervention group, a mobile application will be provided to educate patients, establish two-way interactions between patients and care providers and record patients' symptoms. Those in the control group will receive the usual care. The primary outcome is the change to the depression anxiety stress scales-21 (DASS-21) score from the baseline to 2 weeks after discharge from hospital. It will be measured at the baseline, at the time of discharge, and two weeks later. Ethics and Dissemination: The Ethics committee of Mashhad University of Medical Sciences' approval date was 2020-04-19 with IR.MUMS.REC.1399.118 reference code. Thus far, participants' recruitment has not been completed and is scheduled to end in March 2021. The results will be disseminated in a peer-reviewed journal. Trial Registration: IRCT20170922036314N4 (https://www.irct.ir/trial/47383).

Abstract
Since SARS-CoV-2 infection is rapidly spreading all around the world, affecting many people and exhausting health care resources, therapeutic options must be quickly investigated in order to develop a safe and effective treatment. The present study was designed to evaluate the safety and efficacy of convalescent plasma (CP) for treating severe cases of COVID-19 who developed acute respiratory distress syndrome (ARDS). Among 64 confirmed cases of severe COVID-19 with ARDS in this study, 32 patients received CP besides first line treatment. Their clinical response and outcome in regard to disease severity and mortality rate were evaluated and compared with the other 32 patients in the control group who were historically matched while randomly chosen from previous patients with the same conditions except for receiving CP therapy. Analysis of the data was performed using SPSS software. Patients with plasma therapy showed improvements in their clinical outcomes including a reduction in disease severity in terms of SOFA and APACHE II scores, the length of ICU stay, need for noninvasive ventilation and intubation and also showed an increase in oxygenation. They also showed reduction in mortality which was statistically significant in less severe cases with mild or moderate ARDS. Early administration of the convalescent plasma could successfully contribute to the treatment of severe COVID-19 patients with mild or moderate ARDS at risk of progressing to critical state.

Abstract
PURPOSE Despite the serious consequences of sleep apnea, some patients do not follow their physicians' advice to undergo a sleep study. The present study aimed to determine the rate of adherence and influencing factors in conducting a polysomnography test in patients suspected of obstructive sleep apnea. METHODS This qualitative and quantitative analysis was conducted between July 2017 and November 2019 on patients suspected of sleep apnea. The quantitative analysis aimed at determining the rate of adherence through a retrospective cross-sectional study. The qualitative content analysis was conducted on purposefully selected subgroup of patients suspected of obstructive sleep apnea who were referred for polysomnography. The required data were collected through the semi-structured in-depth interviews and then recorded, transcribed, and analyzed using SPSS.22 and MAXQDA10. RESULTS Quantitative part: Of 311 patients (mean age: 47.6 ± 13.1 years) referred for polysomnography, 283 patients (91%) were at a high risk of developing obstructive sleep apnea. Among those referred for polysomnography, 31% (n = 95) adhered to recommendations for a sleep study. Qualitative part: Factors affecting adherence to polysomnography were categorized as "barriers" and "triggers." Barriers included inadequate knowledge, psychological factors, cost, and the service system. Triggers included adequate knowledge and tangible experience of consequences of the illness. CONCLUSION The majority of patients at risk of developing obstructive sleep apnea did not follow the recommendation for polysomnography, indicating a need for systematic interventions. Among the identified barriers, knowledge and psychological factors are modifiable ones that can be addressed with the patient. We theorize that raising awareness among patients by providing additional information and eliminating concerns may help to increase the rate of adherence. Insurance coverage or subsidy to reduce the sleep study costs may also be an effective strategy to increase adherence to recommendations for polysomnography.

Abstract
Background The rising burden of premature mortality for Non-Communicable Diseases (NCDs) in developing countries necessitates the institutionalization of a comprehensive surveillance framework to track trends and provide evidence to design, implement, and evaluate preventive strategies. This study aims to conduct an organization-based prospective cohort study on the NCDs and NCD-related secondary outcomes in adult personnel of the Mashhad University of Medical Sciences (MUMS) as main target population. Methods This study was designed to recruit 12,000 adults aged between 30 and 70 years for 15 years. Baseline assessment includes a wide range of established NCD risk factors obtaining by face-to-face interview or examination. The questionnaires consist of demographic and socioeconomic characteristics, lifestyle pattern, fuel consumption and pesticide exposures, occupational history and hazards, personal and familial medical history, medication profile, oral hygiene, reproduction history, dietary intake, and psychological conditions. Examinations include body size and composition test, abdominopelvic and thyroid ultrasonography, orthopedic evaluation, pulse wave velocity test, electrocardiography, blood pressure measurement, smell-taste evaluation, spirometry, mammography, and preferred tea temperature assessment. Routine biochemical, cell count, and fecal occult blood tests are also performed, and the biological samples (i.e., blood, urine, hair, and nail) are stored in preserving temperature. Annual telephone interviews and repeated examinations at 5-year intervals are planned to update information on health status and its determinants. Results A total of 5287 individuals (mean age of 43.9 ± 7.6 and 45.9% male) were included in the study thus far. About 18.5% were nurses and midwives and 44.2% had at least bachelor’s degree. Fatty liver (15.4%), thyroid disorders (11.2%), hypertension (8.8%), and diabetes (4.9%) were the most prevalent NCDs. A large proportion of the population had some degree of anxiety (64.2%). Low physical activity (13 ± 22.4 min per day), high calorie intake (3079 ± 1252), and poor pulse-wave velocity (7.2 ± 1.6 m/s) highlight the need for strategies to improve lifestyle behaviors. Conclusion The PERSIAN Organizational Cohort study in Mashhad University of Medical Sciences is the first organizational cohort study in a metropolitan city of Iran aiming to provide a large data repository on the prevalence and risk factors of the NCDs in a developing country for future national and international research cooperation.

Abstract
Although not common, gastrointestinal and liver symptoms have reportedly been the initial presentation of coronavirus disease‐2019 (COVID‐19) in a large group of patients. Therefore, knowing the frequency and characteristics of these manifestations of COVID‐19 is important for both clinicians and health policy makers. A systematic review and meta‐analysis of the available data on the gastrointestinal and liver manifestations of patients with COVID‐19 was performed. PubMed and Scopus databases and Google Scholar search engine were searched for published and unpublished preprint articles up to 10 April 2020. Original studies providing information on clinical digestive symptoms or biomarkers of liver function in patients with polymerase chain reaction confirmed diagnosis of COVID‐19 were included. After quality appraisal, data were extracted. Prevalence data from individual studies were pooled using a random‐effects model. Overall, 67 studies were included in this systematic review and meta‐analysis, comprising a pooled population of 13 251 patients with confirmed COVID‐19. The most common gastrointestinal symptoms were anorexia (10.2%, 95% confidence interval [CI] = 6.2%‐16.4%), diarrhea (8.4%, 95% CI = 6.2%‐11.2%), and nausea (5.7%, 95% CI = 3.7%‐8.6%), respectively. Decreased albumin levels (39.8%, 95% CI = 15.3%‐70.8%), increased aspartate aminotransferase (22.8%, 95% CI = 18.1%‐28.4%), and alanine aminotransferase (20.6%, 95% CI = 16.7%‐25.1%) were common hepatic findings. After adjusting for preexisting gastrointestinal (5.9%) and liver diseases (4.2%), the most common gastrointestinal findings were diarrhea (8.7%, 95% CI = 5.4%‐13.9%), anorexia (8.0%, 95% CI = 3.0%‐19.8%), and nausea (5.1%, 95% CI = 2.2%‐14.3%). Gastrointestinal and liver manifestations are not rare in patients with COVID‐19, but their prevalence might be affected by preexisting diseases. Diarrhea and mild liver abnormalities seem to be relatively common in COVID‐19, regardless of comorbidities Anorexia (10.2%), diarrhea (8.4%), and nausea (5.7%) were the most common gastrointestinal manifestations in confirmed COVID‐19 patients. Serum albumin reduction (39.8%), AST elevation (22.8%), and ALT elevation (20.6%) were the most common hepatic abnormalities in confirmed COVID‐19 patients. Preexisting gastrointestinal and liver diseases were present in 5.9% and 4.2% of COVID‐19 patients. After adjusting for these illnesses, diarrhea (8.7%) became the most prevalent gastrointestinal finding. The prevalence of gastrointestinal and hepatic abnormalities were markedly higher in patients with severe COVID‐19 infection, compared to non‐severe cases.

Abstract
OBJECTIVE Storage at temperatures as low as -80 °C and below (cryopreservation) is considered a method for long-term preservation of cells and tissues, and especially blood vessel segments, which are to be used for clinical operations such as transplantation. However, the freezing and thawing processes themselves can induce injuries to the cells and tissue by damaging the structure and consequently functionality of the cryopreserved tissue. In addition, the level of damage is dependent on the rate of cooling and warming used during the freezing-thawing process. Current methods for monitoring the viability and integrity of cells and tissues after going through the freezing-thawing cycle are usually invasive and destructive to the cells and tissues. Therefore, employing monitoring methods which are not destructive to the cryopreserved tissues, such as bioimpedance measurement techniques, is necessary. In this study we aimed to design a bioimpedance measurement setup to detect changes in venous segments after freezing-thawing cycles in a noninvasive manner. APPROACH A bioimpedance spectroscopy measurement technique with a two-electrode setup was employed to monitor ovine jugular vein segments after each cycle during a process of seven freezing-thawing cycles. MAIN RESULTS The results demonstrated changes in the impedance spectra of the measured venous segments after each freezing-thawing cycle. SIGNIFICANCE This indicates that bioimpedance spectroscopy has the potential to be developed into a novel method for non-invasive and non-destructive monitoring of the viability of complex tissue after cryopreservation.

Abstract
Introduction: Obstructive sleep apnea (OSA) is a highly prevalent sleep-disordered breathing (SDB). Case Report: Two 53- and 51-year-old male cases with daytime sleepiness and opium abuse and severe sleep apnea and long respiratory events duration (200 and 275 seconds respectively) noted in polysomnography were reported at Ebn-e-Sina and Razavi hospitals, in Mashhad, Iran. After positive airway pressure (PAP) therapy respiratory events resolved and patients’ daytime alertness improved. Conclusion: The long duration of sleep apnea could be the result of opium abuse. Therefore, drug history should be carefully considered in the evaluation of SDB patients. The PAP device was effective in the management of sleep respiratory events and the improvement of patient’s complications.

Abstract
Monitoring a biological tissue as a three dimensional (3D) model is of high importance. Both the measurement technique and the measuring electrode play substantial roles in providing accurate 3D measurements. Bioimpedance spectroscopy has proven to be a noninvasive method providing the possibility of monitoring a 3D construct in a real time manner. On the other hand, advances in electrode fabrication has made it possible to use flexible electrodes with different configurations, which makes 3D measurements possible. However, designing an experimental measurement set-up for monitoring a 3D construct can be costly and time consuming and would require many tissue models. Finite element modeling methods provide a simple alternative for studying the performance of the electrode and the measurement set-up before starting with the experimental measurements. Therefore, in this study we employed the COMSOL Multiphysics finite element modeling method for simulating the effects of changing the electrode configuration on the impedance spectroscopy measurements of a venous segment. For this purpose, the simulations were performed for models with different electrode configurations. The simulation results provided us with the possibility of finding the optimal electrode configuration including the geometry, number and dimensions of the electrodes, which can be later employed in the experimental measurement set-up.

Abstract
Zigzag phosphorene nanoribbons have quasi-flat band edge modes entirely detached from bulk states. We analytically study the electronic transport through such edge states in the presence of a localized defect for semi-infinite and finite ribbon widths. Using the tight-binding model, we derive analytical expressions for the Green's function and transmission amplitude of both pristine and defective nanoribbons. We find that the transmission of ribbons with both semi-infinite and finite width is sensitive to the location of a single impurity defect with respect to the edge. By the presence of an impurity on the outermost edge site of the ribbon, the transmission through the edge channel, similar to a one-dimensional chain, strongly suppresses for the entire energy spectrum of the quasi-flat band. In contrast, the transmission of low-energy [Formula: see text] states, is robust as the impurity is moved one position far away from the edge on the same sub-lattice. The analytical calculations are also complemented by exact numerical transport computations using the Landauer approach.

Abstract
Aims and background Littoral cell angioma (LCA) is an uncommon vascular tumor of the spleen recently described and interpreted as the tumoral counterpart of the normally present littoral cells lining the splenic sinus channels of red pulp. The diagnosis of LCA is suggested by a quite characteristic morphology and confirmed by the demonstration of a hybrid endothelial/histiocytic phenotype. Methods Four original and previously unreported cases of LCA are presented. All four splenic vascular tumors were investigated by light microscopy and immunohistochemistry for endothelial and histiocytic markers. Results All four cases were associated with visceral epithelial malignancies (colorectal adenocarcinoma in two cases, renal and pancreatic adenocarcinoma in one case each). One case was also associated with an intracranial tentorial meningioma. Conclusions We consider our findings as a novelty and signal the possible existence of a clinical syndrome. Five of a total of 21 previously reported cases in the literature were also described as being associated with other cancers (non-Hodgkin's lymphoma in two cases, two not further specified tumors of the liver and brain, an epithelial ovarian cancer, and a non-small cell lung cancer in one case each). Close follow-up and careful investigation in search of a second visceral neoplasm are strongly recommended in cases of LCA, but further clinical observations and more in-depth genetic and molecular studies are needed before any valid conclusions can be drawn.

Abstract
BACKGROUND One of the main challenges of surgical treatment in Obstructive Sleep Apnea (OSA) is identifying the correct site of upper airway obstruction in an individual patient. Drug-Induced Sleep Endoscopy (DISE) in sedated patients with obstructive sleep apnea is the technique of choice for revealing anatomic and dynamic collapsible areas. MATERIALS AND METHODS In a prospective cross-sectional study adult patients with OSA documented by polysomnography were evaluated by sleep endoscopy. DISE had been done by an otolaryngologist in the setting of operating room during infusion of propofol and after the start of snoring. Endoscopic findings were recorded and evaluated from the aspect of obstruction level, severity, and multiplicity. RESULTS Twenty OSA patients (60% men) with mean±SD age of 38.9±9.26 years and mean Body Mass Index (BMI) of 26.57 kg/m2 were included in the study. OSA was severe in 11(55%) and moderate in 5(25%) subjects. Unilevel airway collapse was observed as retropalatal in 4(20%) and retrolingual in 3(15%) subjects. Multilevel collapse had been observed in the other 13(65%) patients. Most patients (65%) had multilevel obstruction especially those with BMI>30 (p<0.05). With increasing BMI, obstruction changed from unilevel to multilevel. None of the subjects showed complications with propofol or endoscopy procedure. CONCLUSION Our study showed DISE is safe, easy to perform, and informative in OSA patients. In particular, we observed a significant association between obesity and multilevel upper airway collapse.

Abstract
Rapid development in the field of tissue engineering necessitates implementation of monitoring methods for evaluation of the viability and characteristics of the cell cultures in a real-time, non-invasive and non-destructive manner. Current monitoring techniques are mainly histological and require labeling and involve destructive tests to characterize cell cultures. Bioimpedance measurement technique which benefits from measurement of electrical properties of the biological tissues, offers a non-invasive, label-free and real-time solution for monitoring tissue engineered constructs. This review outlines the fundamentals of bioimpedance, as well as electrical properties of the biological tissues, different types of cell culture constructs and possible electrode configuration set ups for performing bioimpedance measurements on these cell cultures. In addition, various bioimpedance measurement techniques and their applications in the field of tissue engineering are discussed.

Abstract
In recent decades, the relation of carotid artery intima-media thickness (IMT) as a marker of atherosclerosis with snoring and sleep disorders has been drawing attention. The aim of this study was to evaluate the relation of carotid arteries IMT with snoring in type 2 diabetic patients. This cross-sectional study was performed on type 2 diabetes patients referring to Mashhad University of Medical Sciences' clinics. The stop Bang, Epworth sleepiness scale, and Stanford questionnaires were used for evaluation of daily sleepiness and snoring. For assessment of carotid artery thickness, Madison X8 ultrasound with 10 MHz superficial probes was utilized. The data were entered into SPSS software, and then the ANOVA test with Turkey, chi-square comparison technique, and Kruskal Wallis with Mann-Whitney U technique was used. The level of significance was considered P≤0.05. In total 80 patients (37 snorers and 43 non-snorers) entered the study. The mean carotid artery IMT in the group of snoring patients (0.72±0.17) was significantly higher than non-snorers (0.56±0.17) (P<0.001). Frequency of daily based on Stanford and ESS questionnaires was 23.8% and 39.2%. The association of sleepiness and snoring was confirmed by Stanford and ESS questionnaires with P=0.026 and P=0.007. Patients with higher risk of apnea had higher thickness of the mean carotid artery IMT (P<0.001). The mean carotid artery IMT had a positive significant relation with age (P=0.002), serum creatinine level (P<0.002), blood cholesterol (P=0.02) and HbAIC level (P=0.04). Findings of this study provides evidence on the relation of carotid artery IMT in diabetic patients with snoring independent of other effective factors. Also, results showed that snoring is associated with increased daily sleepiness and patients with higher risk of apnea had higher thickness of the mean carotid artery IMT.
