Abstract
OBJECTIVES The voice quality of patients with Coronavirus Disease 2019 (COVID-19) seems to be affected due to lower and upper respiratory involvement. Patient-based voice assessment scales are important clinical measures to diagnose voice disorders and monitor treatment outcomes in COVID-19 patients. This study compared vocal fatigue between COVID-19 patients and those with normal voices. Furthermore, the relationship between vocal fatigue and acoustic voice parameters of COVID-19 patients was evaluated. METHODS This cross-sectional study enrolled 30 laboratory-confirmed patients with COVID-19 (18 males and 12 females) and 30 healthy individuals with normal voices (14 males and 16 females) to compare their respiratory or phonatory parameters. The Persian versions of the Consensus Auditory Perceptual Evaluation of Voice (CAPE-V) and the vocal fatigue index (VFI) were conducted before and after reading the text. The Jitter, shimmer, maximum phonation time, and harmonic-to-noise ratio (HNR) were analyzed by Praat software based on the recorded voices of CAPE-V tasks. The acoustic assessment and VFI questionnaire results were compared between COVID-19 patients and the control group. RESULTS There were significant differences between COVID-19 patients and their healthy counterparts in all VFI subscales (P < 0.001). Moreover, after reading the text, we found significant differences between the two groups regarding Jitter, shimmer, and HNR of /a/ and /i/ vowels (P < 0.05). Our findings also indicated a significant correlation between symptom improvement with rest and acoustic parameters in all tasks, except the Jitter of /a/ before reading the text. CONCLUSION Patients with COVID-19 showed significantly more vocal fatigue than people with normal voices after reading the text. Moreover, there was a significant relationship between Jitter, shimmer, and HNR and the tiredness of voice and physical discomfort subscales of VFI.

Abstract
Introduction: Elevated pre-gestational body mass index (obese/overweight) and improper gestational weight gain are important risk factors for predicting adverse pregnancy outcomes. Objective: We aimed to identify the association between pre-pregnancy body mass index (BMI) and gestational weight gain on birth outcomes. Materials and Methods: Data from this retrospective cohort study were extracted from 1457 (out of 1800) pair health records belonging to the pregnant mother and infants at Ahvaz Iran health care centers from 2010 to 2018. Ten public health care centers were randomly selected from the headquarters west and east of Ahvaz City. The samples were selected based on the inclusion criteria. They divided into different groups based on BMI (underweight, normal, overweight, and obese) and gestational weight gain (GWG) groups (inadequate and excessive versus adequate). Pregnancy outcome was analyzed according to the GWG during pregnancy for each BMI group through multivariable multinomial logistic regression. Relationships between maternal BMI, GWG, and offspring weight were examined. The analysis of covariance (ANCOVA) was used with adjusting the baseline values. The risks for adverse birth weight outcomes in women with different pre-pregnancy BMIs and GWGs were tested using the multivariable multinomial logistic regression analysis. Results: The Mean±SD of maternal age was 28.36±5.60 years. The Mean±SD birth weight was 3271.37±486.57 g. About 4.5%, 89.3%, and 6.2% of newborns were low birth weight, normal weight, and macrosomia, respectively. Also, 46.4% of women had weight gain above the guidelines. The increased risk for large for gestational age in overweight mothers (odds ratio [OR] =3.18, 95%CI; 0.45-7.29, P=0.007) and an increased risk for small for gestational age in those mothers with gestational weight gain below the guidelines (OR=2.9, 95%CI; 1.16- 7.45, P=0.02). An increased risk of large for gestational age, low birth weight, and macrosomia were observed in overweight mothers with gestational weight gain out of the guidelines. An increased association was found between the maternal pre-pregnancy BMI and fasting blood sugar in 24 to 28 weeks of gestation. Hence, hyperglycemia is related to the incidence of macrosomia (OR=3.58, 95%CI; 1.70-7.66, P=0.0001). Conclusion: Managing maternal weight with respect to reproductive health care is required for all women in childbearing age (before and during pregnancy) to reduce the adverse pregnancy outcome.

Abstract
Background and aims The main goal of the present study is to investigate the incidence of Rotavirus co-infection in COVID-19 patients. Methods and Results Fecal samples of COVID-19 patients with gastrointestinal symptoms which had positive PCR- were collected from Abadan's hospital, Iran during the period December 2020 to January 2021. Samples were analyzed by RT-PCR to determine the presence of Rotavirus. Finally, the total samples size of 37 were included in this study. The mean age of patients was 48.22 years. Abdominal pain alone was detected in 48.65% of the patients. At least one gastrointestinal symptom was detected in all of the patients. Diarrhea and fever were seen in 13.51% and 59.46% of patients, respectively. Nausea and vomiting were seen in 5.41% of the patients. RT-PCR showed no infection of Rotavirus among the patients. Conclusion Gastrointestinal symptoms related to COVID-19 are common. More studies is need among these patients groups for investigate co-infection with other fecal viral shedding carries, due to a worse prognosis and its association with disease severity.

Abstract
BACKGROUND AND AIMS
Electrolyte abnormalities are common among patients with coronavirus disease 2019 (COVID-19). This study aims to investigate the electrolyte changes in severe and non-severe COVID-19 patients. Hypocalcaemia, hypomagnesaemia and hypoalbuminemia and their relationship with the severity of symptoms and prognosis will also be determined.
METHOD
We enrolled 270 COVID-19 patients. Serum tests were taken from each patient on the day of admission to check the level of variables. Thereon, calcium, magnesium and phosphorus levels were measured twice a week and albumin levels were measured once a week. Variables such as PTH and 25 (OH) D were measured once at the beginning of the study. Other laboratory results like complete blood count, C-reactive protein and clinical data such as arterial blood oxygen levels, length of stay in the ICU and the treatment regimen were extracted from patients' medical records and history. Finally, patients were categorized as mild, moderate, severe and critical group based on the severity of the disease. The data analyses were carried out via SPSS software (version 21.0).
RESULTS
Of 270 patients, 135 people (50%) were men. The mean age of patients was 46.7 years. Based on the severity of the disease, 91 patients had mild disease, 90 patients presented with moderate disease, 54 patients were in severe condition and 35 patients were critical. Hypocalcaemia (Ca 2+ ≤8.6 mg/dL) was detected in 49 patients (18.1%) on admission. The mean of serum magnesium, phosphorus and albumin levels on admission was 2.2 ± 0.22 mEq/L, 3.39 ± 0.79 mg/dL and 4.49 ± 0.66g/dL, respectively. Phosphorus level was lower than 2.63 mg/dL in 11 patients (4.07%) and 43 patients (15.92%) had hypoalbuminemia. The mean 25(OH) D level was 32.92 ± 10.29 μg/L; therefore, 182 patients (67.40%) fall within the normal range (>30 μg/L).
CONCLUSION
Patients with mild and moderate disease tend to develop hypocalcaemia, hypoalbuminemia and hypomagnesaemia more often than severe and critical COVID-19 patients during treatment. 25(OH) D deficiency rate was higher in the moderate group. Patients with hypocalcaemia during treatment had higher mortality than other patients. We recommend electrolytes be measured at initial presentation and serially monitored during hospitalization in order to establish timely and appropriate corrective actions and prevent the serious complications of the disease.

Abstract
Since the onset of the coronavirus disease 2019 (COVID-19) pandemic, the clinical manifestations of the virus have undergone many changes. Recently, there have been many reports on gastrointestinal symptoms in COVID-19 patients. This study is aimed to perform a detailed phylogenetic study and assessment of different SNVs in the RNA genome of viruses isolated from fecal samples of patients with COVID-19 who have gastrointestinal symptoms, which can help better understand viral pathogenesis. In the present study, 20 fecal samples were collected by written consent from COVID-19 patients. According to the manufacturer's protocol, virus nucleic acid was extracted from stool samples and the SARS-CoV-2 genome presence in stool samples was confirmed by RT-PCR assay. Three viral genes, S, nsp12, and nsp2, were amplified using the reverse transcription polymerase chain reaction (RT-PCR) method and specific primers. Multiple sequencing alignment (MSA) was performed in the CLC word bench, and a phylogenetic tree was generated by MEGA X based on the neighbor-joining method. Of all cases, 11 (55%) were males. The mean age of the patients was 33.6 years. Diabetes (70%) and blood pressure (55%) were the most prevalent comorbidities. All 20 patients were positive for SARS-CoV-2 infection in respiratory samples. Molecular analysis investigation among 20 stool samples revealed that the SARS-CoV-2 genome was found among 10 stool samples; only three samples were used for sequencing. The polymorphism and phylogenetic analysis in SARS-CoV-2 showed great similarity among all of the evaluated genes with the Wuhan reference sequence and all of the current variants of concern (VOCs). The current study represents a great similarity in polymorphism and phylogenetic analysis of the SARS-CoV-2 isolates with the Wuhan reference sequence and all of the current VOC in the particular evaluated partial sequences of S, nsp12, and nsp2.

Abstract
Background Tranilast is a potential NLRP3 inflammasome inhibitor that may relieve progressive inflammation due to COVID-19. Aim of the study To evaluate the therapeutic effects of Tranilast in combination with antiviral drugs in non-ICU-admitted hospitalized patients with COVID-19. Methods This study was an open-label clinical trial that included 72 hospitals admitted patients with severe COVID-19 at Razi Hospital, Ahvaz, Iran, from July 2020–August 2020. These patients were randomly assigned in a 1:1 ratio to control (30) and intervention groups (30). Patients in the control group received antiviral therapy, while patients in the intervention group received Tranilast (300 mg daily) in addition to the antiviral drugs for Seven days. The collected data, including the expression of inflammatory cytokine, laboratory tests, and clinical findings, was used for intragroup comparisons. Results The intervention group showed significantly lower levels of NLR (p = 0.001), q-CRP (p = 0.002), IL-1 (p = 0.001), TNF (p = 0.001), and LDH (p = 0.046) in comparison with the control group. The effect of intervention was significant in increasing the o2 saturation (F = 7.72, p = 0.007). Long hospitalization (four days or above) was 36.6% in the Tranilast and 66.6% in the control group (RR = 0.58; 95% CI: 0.38–1.06, p = 0.045). In the Tranilst and control groups, one and four deaths or hospitalization in ICU were observed respectively (RR = 0.31; 95% CI: 0.03–2.88, p = 0.20). Conclusions Tranilast might be used as an effective and safe adjuvant therapy and enhance the antiviral therapy's efficacy for managing patients with COVID-19.

Abstract
Background This study was aimed to evaluate the antibiotic resistance, biofilm formation, and genetic diversity of carbapenem-resistant Pseudomonas aeruginosa (CRPA) strains isolated from four types of nosocomial infections (NIs) including urinary tract infection (UTI), ventilator-associated pneumonia (VAP), surgical site infection (SSI), and bloodstream infection (BSI). Methods and results In total, 115 isolates of NIs-causing P. aeruginosa were collected from NIs. Antibiotic susceptibility testing (AST) was performed using disk diffusion method and minimum inhibitory concentrations. Biofilm formation was tested on 96-well polystyrene microtiter plates (MTP). CRPA isolates were genotyped using multiple-locus variable number of tandem repeat analysis (MLVA). The most resistance and susceptibility rates were observed to amikacin (70.6%) and colistin (96.1%), respectively. Colistin and meropenem were the most active antimicrobial agents in VAP, SSI, and BSI. While, colistin and cefepime were the most active in UTIs. In total, 52.2% (n = 60/115) of P. aeruginosa isolates were carbapenem resistant, of which 95.0%, 55.0%, and 5.0% were multidrug-resistant, extensively drug-resistant, and pandrug-resistant, respectively. There was a significant association between resistance to carbapenem and resistance to other antibiotics except for piperacillin/tazobactam. The biofilm production of CRPA isolates was 95.0%, of which 23.3% were strong biofilm producers. Based on MLVA, there were 34 different types of CRPA isolates classified into three main clusters and 5 sub clusters. Conclusion The association of CRPA with other antibiotic resistance, the high rates of biofilm production, and the high genetic diversity of the isolates may be a warning of the need for a careful surveillance program.

Abstract
Background: COVID-19 spread rapidly throughout the world and affected many people. The purpose of this study was to investigate the epidemiological characteristics of patients with COVID-19 in southwest of Iran from February 19 to June 20, 2020.
Methods: In this retrospective study, the epidemiological characteristics of 7313 patients with COVID-19 in southwest of Iran were analyzed and reported from February 19, 2020, to the end of Jun,2020. Data were extracted from electronic records in hospitals. Sex ratio and mortality rate of the disease were calculated. A multiple logistic regression analysis was used to evaluate the factors affecting mortality.
Results: From all patients studied, 3920 (53.5%) were men and 2066 (28.24%) were in the age 30 to 40 years age group. The case fatality rate of the disease based on the total number of patients (hospitalized and nonhospitalized) was 4.84%. The highest mortality rate was seen in patients with various cancers and in those aged over 80 years. The most common symptoms in patients were fever and cough, diabetes, hypertension, and cardiovascular diseases. Logistic regression results also showed that the chances of death in the 70-60 and 80-70 years age group were 5.94 (OR, 5.94; 95% CI, 2.14-16.43) and 8.63 (OR, 8.63, 95% CI, 3.09-24.14) compared to 10-20 years age group.
Conclusion: These results indicate the need to increase primary care, provide the necessary equipment to treat patients, and more importantly, early identification of patients and treatment for them.

Abstract
Background The combination of sofosbuvir and daclatasvir has shown preliminary efficacy for hospitalized patients with COVID-19 in four open-label studies with small sample sizes. This larger trial aimed to assess if the addition of sofosbuvir/daclatasvir to standard care improved clinical outcomes in hospitalized patients with COVID-19. Methods This was a placebo-controlled, double-blind, randomized clinical trial in adults hospitalized with COVID-19 at 19 hospitals in Iran. Patients were randomized to oral sofosbuvir/daclatasvir 400/60 mg once-daily or placebo in addition to standard of care. Patients were included if they had positive PCR or diagnostic chest CT, O2 saturation <95% and compatible symptoms. The primary outcome was hospital discharge within 10 days of randomization. Secondary outcomes included mortality and time to clinical events. The trial is registered on the Iran Registry of Clinical Trials under IRCT20200624047908N1. Results Between July and October 2020, 1083 patients were randomized to either the sofosbuvir/daclatasvir arm (n = 541) or the placebo arm (n = 542). No significant difference was observed in the primary outcome of hospital discharge within 10 days, which was achieved by 415/541 (77%) in the sofosbuvir/daclatasvir arm and 411/542 (76%) in the placebo arm [risk ratio (RR) 1.01, 95% CI 0.95–1.08, P = 0.734]. In-hospital mortality was 60/541 (11%) in the sofosbuvir/daclatasvir arm versus 55/542 (10%) in the placebo arm (RR 1.09, 95% CI 0.77–1.54, P = 0.615). No differences were observed in time to hospital discharge or time to in-hospital mortality. Conclusions We observed no significant effect of sofosbuvir/daclatasvir versus placebo on hospital discharge or survival in hospitalized COVID-19 patients.

Abstract
Background Different resistance mechanisms for multidrug-resistant tuberculosis (MDR-TB) and extensively drug-resistant tuberculosis (XDR-TB) have been reported. Although mutations in target genes are the main cause of drug resistance, efflux pumps (Eps) also play an important role in this process. Here, we investigated the overexpression of five putative EP genes plus gene mutations in MDR-TB clinical isolates. Methods A total of 27 M. tuberculosis (Mtb) clinical isolates including, 22 MDR and 5 sensitive isolates were analyzed. Minimum inhibitory concentrations (MIC) were determined in the absence and presence of efflux inhibitor. The expression level of 5 EP genes (Rv3065, Rv2942, Rv1258c, Rv1410c, Rv2459) was investigated by quantitative real time PCR (RT-qPCR). DNA sequencing of rpoB, katG, and inhA promoter was done. Results Among the 22 MDR-TB isolates, 13 (59.1%) showed significant overexpression (>4-fold) for at least one EP gene. The expression levels of 5 genes were significantly higher (P < 0.05) in MDR-TB isolates than sensitive isolates. The Rv3065 (22.7%), and Rv1410c (18.2%) were found to be the most commonly overexpressed EPs. The observed MICs were as follows: RIF (2 to >128 μg/ml) and INH (2-32 μg/ml). After efflux pump inhibitor exposure, 10/22 (45.45%) isolates showed a decrease in MIC of INH, and 17/22 (77.27%) isolates showed a decrease in MIC of RIF. Of the isolates that overexpressed, 4 isolates lacked mutation in inhA, rpoB, and katG genes and 10 ones lacked mutation in inhA and katG. Conclusion The results showed that overexpression of EP genes in Mtb isolates, besides target gene mutations can contribute to the development of MDR phenotype.

Abstract
INTRODUCTION Due to the upper and lower respiratory involvement in coronavirus disease 2019 (COVID-19), the voice quality of these patients is expected to be impaired. In this study, we aimed to conduct an auditory-perceptual evaluation of the vocal characteristics of patients with different severities of COVID-19. METHODS One hundred two patients with mild, moderate, or severe COVID-19 as well as 30 healthy individuals were recruited to compare their respiratory/phonatory parameters. The Persian version of the CAPE-V and GRBAS scales, along with the maximum phonation time and s/z ratio values were used to evaluate the severity of respiratory/phonatory disorders during verbal tasks in the participants. RESULTS Significant differences were found between the subgroups of patients and their healthy counterparts in all respiratory/phonatory parameters (p ≤ 0.03) except the s/z ratio (p = 0.81). CONCLUSIONS Based on auditory-perceptual assessments, patients with COVID-19 showed dysphonia. The severity of dysphonia was significantly different among patients with different severities of COVID-19. Smoking can also play a significant role in vocal dysfunction in COVID-19 patients.

Abstract
The management of multidrug-resistant (MDR) and extensively drug-resistant tuberculosis (XDR-TB) presents a main challenge and the drug options for treating these infections are very limited. Linezolid (LNZ) has recently been approved for the treatment of MDR and XDR-TB. But, there are narrow data on genotypic and phenotypic LNZ resistance in clinical isolates. So, we aimed to determine the prevalence of LNZ resistance and to identify the mutations associated with LNZ resistance among clinical MDR-TB isolates. The minimum inhibitory concentration (MIC) values of LNZ for 22 MDR-TB isolates were determined by broth microdilution method. All MDR-TB isolates were sequenced in the rrl and rplC genes conferring LNZ resistance. LNZ resistance was found in 3 (13.6%) of 22 MDR-TB isolates. The MICs of LNZ were 8 μg/mL for two isolates and 16 μg/mL for one isolate. The 421 (A/G) and 449 (T/A) mutations in rplC gene were detected in one of the LNZ-resistant isolates. There was no mutation in rrl gene. The results reveal that the prevalence of LNZ-resistant isolates is 13.6% among MDR-TB isolates and drug susceptibility testing (DST) against LNZ is useful in the management of complicated and drug-resistant cases. However, further studies could identify other possible genetic mechanism of resistance in TB.

Abstract
OBJECTIVES Sofosbuvir and daclatasvir are direct-acting antivirals highly effective against hepatitis C virus. There is some in silico and in vitro evidence that suggests these agents may also be effective against SARS-CoV-2. This trial evaluated the effectiveness of sofosbuvir in combination with daclatasvir in treating patients with COVID-19. METHODS Patients with a positive nasopharyngeal swab for SARS-CoV-2 on RT-PCR or bilateral multi-lobar ground-glass opacity on their chest CT and signs of severe COVID-19 were included. Subjects were divided into two arms with one arm receiving ribavirin and the other receiving sofosbuvir/daclatasvir. All participants also received the recommended national standard treatment which, at that time, was lopinavir/ritonavir and single-dose hydroxychloroquine. The primary endpoint was time from starting the medication until discharge from hospital with secondary endpoints of duration of ICU stay and mortality. RESULTS Sixty-two subjects met the inclusion criteria, with 35 enrolled in the sofosbuvir/daclatasvir arm and 27 in the ribavirin arm. The median duration of stay was 5 days for the sofosbuvir/daclatasvir group and 9 days for the ribavirin group. The mortality in the sofosbuvir/daclatasvir group was 2/35 (6%) and 9/27 (33%) for the ribavirin group. The relative risk of death for patients treated with sofosbuvir/daclatasvir was 0.17 (95% CI 0.04-0.73, P = 0.02) and the number needed to treat for benefit was 3.6 (95% CI 2.1-12.1, P < 0.01). CONCLUSIONS Given these encouraging initial results, and the current lack of treatments proven to decrease mortality in COVID-19, further investigation in larger-scale trials seems warranted.

Abstract
BACKGROUND & OBJECTIVES West Nile virus (WNV) is a neurotropic Flavivirus transmitted to humans through mosquito bites. As there is no specific antiviral treatment or approved vaccine against WNV, control and prevention of the infection is the best strategy to reduce the burden of WNV-related diseases. The circulation of WNV has been indicated in several regions of Iran including the Khuzestan province. Considering the complex ecology of WNV, the latest data are necessary for the implementation of preventive measures. Therefore, the present study was designed to provide updated information on the seroepidemiology of WNV in Khuzestan province. METHODS A total of 408 sera were taken from volunteers living in Khuzestan. The presence of specific immunoglobulin G (IgG) antibody against WNV was tested by the enzyme-linked immunosorbent assay (ELISA) method. All the data and participants' demographic information were analyzed by SPSS and Esri's ArcMap GIS software programs. RESULTS Anti-WNV IgG antibody was detected in 97 (23.8%) out of the 408 tested sera. The highest seropositivity rate was observed in cases aged between 20-29 yr and the lowest seropositivity rate was seen in those <19 yr of age (p = 0.001). There was no statistically significant association between WNV infection and gender, occupation, and educational level. The majority of positive cases were from the city of Ahvaz (47 cases, 48.4%) and Andimeshk (32 cases, 33%). INTERPRETATION & CONCLUSION This study supports the earlier findings suggesting the circulation of WNV in Khuzestan province. Therefore, the implementation of an integrated surveillance system and training of health care workers and general population regarding the infection would be valuable to reduce the burden of possible outbreaks.

Abstract
Introduction: Despite the great efforts to control tuberculosis (TB), the disease is still one of the major health challenges throughout the world. The basic treatment for TB is drug therapy. Currently, the main anti-tuberculosis drugs with major use in the treatment and control of the disease are isoniazid, rifampin, pyrazinamide, ethambutol, and streptomycin. One of the serious crises in controlling TB epidemic is diagnosis and treatment of patients with Multidrug Resistant Tuberculosis (MDR-TB MDR). The purpose of the study was to examine and evaluate the resistance of mycobacterium TB strains isolated from specimens of newly diagnosed smear positive pulmonary TB to isoniazid and rifampin using molecular methods and their risk factors. Methods: Sputum samples of newly diagnosed smear positive pulmonary TB patients were prepared, collected, and sent to Reference Laboratory in Ahvaz. DNA of mycobacterium tuberculosis was prepared from the samples using Qiagen kit according to the instructions of the manufacturing company. Isoniazid resistance was evaluated using specific primers for inhA and KatG genes. Rifampin resistance was evaluated using MAS-PCR method with three specific alleles of rpobB codons and codons 516, 526 and 531. Results: Mycobacterium tuberculosis resistance to Isoniazid was 7.3%, to Rifampin 5.5% and to both drugs 1.8%. In our study, there were no association between drug resistance and gender, age, prison history, smoking, drug use, underlying disease, occupation, and HIV. Conclusion: According our findings that include prevalence of 7.3% Isoniazide resistance, 5.5% Rifampin resistance and 1.8% to both drugs, evaluating all newly diagnosed patients for resistance to standard anti-tuberculosis treatment seems rational.

Abstract
With sand flies as the main vectors, Leishmania species cause ancient zoonotic diseases called leishmaniasis. Iran is an endemic country regarding cutaneous leishmaniasis. A number of 100 smear slides were collected from cutaneous lesions referred to Ahvaz health centers. The DNA was extracted and ITS1-PCR using LITSR and L5.8S primer pair was performed to detect the genus Leishmania. Then, enzymatic digestion of PCR products was done by HaeIII (species detection), TaqI (strain detection), DpnI and HpaII (mutation assessment). Furthermore, 50 samples were sent for sequencing. Microscopic examination showed amastigote form in all 100 slides. Also, molecular identification confirmed the infection of all cases to Leishmania genus, representing a 350 bp band. HaeIII digestion yielded 150 and 200 bp bands, indicating Leishmania major, while 130 and 200 bp fragments following TaqI digestion suggested A1 strain of the parasite. Moreover, no likely mutations was detected in ITS1 fragment of obtained parasites using DpnI (140 and 200 bp digestion) and HpaII (without digestion). The sequencing result also was consistent with our findings, having 100% homology to A1 strain sequence (AY550178). Leishmania major A1 strain was the predominant species in clinical samples of Ahvaz. Nevertheless, future researches should address the parasite strains in other foci and hosts of epidemiological significance.

Abstract
BACKGROUND The current study was aimed to assess the prevalence of intestinal parasitic infections (IPIs) in persons who were referred to selected hospitals of Abadan and Khorramshahr cities, in the southwest of Iran. MATERIALS AND METHODS In this descriptive cross-sectional study, 43200 and 28821 stool specimens were gathered from Abadan and Khorramshahr cities, respectively, during four consecutive years (2014-2017). RESULTS A decreasing trend was seen in the prevalence rate of IPIs in Abadan and Khorramshahr cities. The overall prevalence of IPIs was estimated to be 5.82% and 6.11% in Abadan and Khorramshahr cities, respectively. In Abadan city, the proportion of IPIs in male persons with 56% was higher than females 44%, while in Khorramshahr city, more prevalence was observed in females (54% vs. 46%). Moreover, according to the season, the highest prevalence was recorded in Spring (30.4%) and Summer (31.1%) in Abadan and Khorramshahr cities, respectively. We found Giardia lamblia, as the most frequent parasite in studied individuals of both cities (Abadan: 2.92%; 1261/43200 and Khorramshahr: 3.15%; 908/28821). Other parasites were as follows: Entamoeba histolytica/dispar, E. coli, E. hartmanni, Blastocystis hominis, Hymenolepis nana, Enterobius vermicularis, Strongyloides stercoralis, and Taenia spp. CONCLUSION This was the first study on the prevalence of IPIs in Abadan and Khorramshahr cities, southwest of Iran. Intestinal parasites are still the main public health concern in these regions. Health education, improving sanitary conditions, screening and treatment of infected people, particularly in rural and semi-urban areas can be helpful.

Abstract
Background The emergence of drug resistance among Mycobacterium tuberculosis (MTB) strains is a serious health concern worldwide. The development of rapid molecular diagnostic methods in recent years has a significant impact on the early detection of resistance to major anti-TB drugs in MTB isolates, which helps in employing appropriate treatment regimen and prevents the spread of drug-resistant strains. This study was designed to evaluate the efficacy of real-time PCR and high-resolution melting (HRM) curve analysis for the determination of resistance to rifampin (RIF), isoniazid (INH), and ofloxacin (OFX) in MTB isolates and to investigate their resistance-related mutations. Methods HRM analysis was performed to screen 52 (32 drug-resistant and 20 fully susceptible) MTB clinical isolates for mutations in rpoB, katG, mab-inhA, and gyrA genes. The HRM results were then confirmed by DNA sequencing. Results In total, 32 phenotypically resistant isolates, comprising 18 RIF-, 16 INH-, and five OFX- resistant strains, were investigated. HRM analysis successfully identified 15 out of 18 mutations in rpoB, 14 out of 16 mutations in katG and mab-inhA, and four out of five mutations in gyrA conferring resistance to RIF, INH, and OFX, respectively. The obtained sensitivity and specificity, respectively, for HRM in comparison with phenotypic susceptibility testing were found to be 83.3% and 100% for RIF, 87.5% and 100% for INH, and 80% and 100% for OFX. In five resistant strains (12.8%), no mutation was detected by using HRM and DNA sequencing. Conclusion HRM assay is a rapid, accurate, and cost-effective method possessing high sensitivity and specificity for the determination of antibiotic resistance among MTB clinical isolates and screening of their associated mutations. This method can generate results in a shorter period of time than taken by the phenotypic susceptibility testing and also allows for timely treatment and prevention of the emergence of possible MDR strains.

Abstract
Botulism is one of the most important foodborne diseases and is caused by Clostridium botulinum toxin. The main manifestations are flaccid muscle paralysis and cranial nerve palsies. Botulism is an essential health problem because of its high mortality. The diagnosis of botulism, especially in sporadic cases, is a medical challenge and a high clinical suspicion is necessary for early recognition. So, every physician should be familiar with its signs and symptoms for early detection and treatment. We describe a family with dysphasia and acute paralysis after the ingestion of locally made cheese. The clinical presentations of the 1st patient were similar to myasthenic crisis and she, therefore, received plasma exchange. After the appearance of similar symptoms in the other family members, they were treated with polyvalent botulinum antitoxin and diagnosis was confirmed by toxicology and detection of serotype A botulinum toxin in cheese and stool samples. Uncommon clinical presentations and unusual sources of botulinum toxin should be kept in mind because of the importance of early diagnosis and treatment.

Abstract
Background Crimean-Congo hemorrhagic fever (CCHF) is an arboviral zoonotic disease transmitted to humans mainly through the bite of blood-sucking Ixodidae ticks and also via contact with the blood and tissues of infected livestock. Objectives This study is a retrospective descriptive survey based on data collected from the health center of Khuzestan province, Iran, during 1999 - 2015. Patients and Methods Patients with symptoms of severe headache, high fever, and bleeding were evaluated. Laboratory tests and serological or molecular assays were used to detect probable and confirmed cases, respectively. The epidemiological parameters of this study were analyzed on the basis of probable cases. Results A total of 42 patients were diagnosed as probable cases, and 17 of these (42.5%) were confirmed serologically. Two peaks of the disease occurred in Khuzestan province, in 2003 and 2010, with seven cases each of those years, leading to the deaths of five and two patients, respectively. Men and women comprised 57.1% and 42.9% of the patients, respectively. Of all probable cases, 64.3% were from urban areas and 35.7% were from rural areas. The age groups of 10 - 19 and 20 - 29 years, with a frequency of 26.2% in each group, were exposed to the most infections. Farmers and housewives were the highest at-risk occupational groups with a frequency of 28.6% and 26%, respectively. Fever, bleeding, and thrombocytopenia were reported in 95% of the patients, and the case-fatality ratio was calculated to be 28.6% (12 of 42 cases). Conclusions Continuous training is necessary to improve the knowledge and awareness of the highest-risk groups with regard to the transmission modes, prevention, symptoms, and treatment of this disease.

Abstract
BACKGROUND Prompt diagnosis and treatment of latent tuberculosis (TB) infection (LTBI) are needed to control TB. The aim of the study was to compare the performance of Quanti FERON-TB test (QFT) with conventional TST for the diagnosis of LTBI. METHODS In this analytical - comparison study, we enrolled 87 nurses working in teaching hospitals in Ahvaz. All study subjects were tested by TST. TST results were interpreted as positive if induration was more than 10 mm. If the level of QFT after stimulation was equal or greater than 0.35 IU/ml, test was considered as positive. Data were analyzed with SPSS program. QFT results compared with induration in TST and its relation to all variables were investigated. RESULTS The rate of LTB diagnosis by TST and QFT was 31% and 35.6%, respectively. There was no significant difference between TST and QFT in LTB diagnosis (P=0.62). Among the 56 subjects who were TST- negative, 14 cases (approximately 25%) were QFT- positive and 42 (75%) were QFT- negative. Among the 31 cases (35.6%) that had TST- positive, 13 (42%) were QFT-positive and 18 (58%) were QFT- negative. The overall percent agreement was 63.2% (k=0.139, P=0.69), discordance %=15.9-20.7, sensitivity= 41.5% and specificity=75.5%. CONCLUSION Diagnostic value of QFT is similar to TST, when there is strong clinical and epidemiological evidence of LTB in a nurse with negative TST, adding QFT to diagnostic evaluation is associated with increased rate of LTB diagnosis.

Abstract
Ahvaz, the capital city of Khuzestan Province, which produces Iran's most oil, is on the rolls of fame in view of air pollution. It has also suffered from dust storm during the recent two decades. So, emissions from transportation systems, steel, oil, black carbon, and other industries as anthropogenic sources and dust storm as a new phenomenon are two major concerns of air pollution in Ahvaz. Without any doubt, they can cause many serious problems for the environment and humans in this megacity. The main objective of the present study was to estimate the impact of ground-level ozone (GLO) as a secondary pollutant on human heath. Data of GLO in four monitoring stations were collected at the first step and they were processed and at the final step they were inserted to a health effect model. Findings showed that cumulative cases of cardiovascular and respiratory deaths which attributed to GLO were 43 and 173 persons, respectively. Corresponding RR for these two events were 1.008 (95% CI) and 1.004 (95% CI), respectively. Although we did not provide a distinction between winter and summer in case of mentioned mortalities attributed to GLO, ozone concentrations in winter due to more fuel consumption and sub adiabatic condition in tropospheric atmospherewere higher than those GLO in summer.

Abstract
Background: Diagnosis of tuberculosis (TB) is not always easy, thus employing methods with a short duration and acceptable sensitivity and specificity is necessary to diagnose TB. Objectives: The aim of this study was to investigate the diagnostic value of serum adenosine deaminase (ADA) level for diagnosis of pulmonary tuberculosis. Patients and Methods: A total of 160 sex and age-matched subjects were included in this study, and were divided to four groups; forty patients with pulmonary tuberculosis (PTB) diagnosed based on the national TB program (NTP), forty patients with non-tuberculosis bacterial pneumonia, forty patients with lung cancer and forty people who were healthy in every respect. Serum adenosine deaminase activity in patients of each group was measured by the Giusti and Galanti calorimetry method using a commercial kit (Diazyme, USA). The ANOVA analysis was used to compare groups for quantitative variables. Results: Mean serum ADA level in the PTB group was clearly higher than the mean serum ADA in the other three groups. Mean serum ADA was 26 IU/L in PTB patients, 19.48 IU/L in patients with pneumonia, 15.8 IU/L in patients with lung cancer, and 10.7 IU/L in the control group (P < 0.05). In regard to the cut off value of 26 IU/L for ADA in patients with PTB sensitivity and specificity was defined as 35% and 91%, respectively. Conclusions: Serum ADA activity with high specificity percentage may be a useful alternative test in restricted resource areas to rule out diagnosis of PTB. However, serum ADA activity is not a useful tool for TB diagnosis.

Abstract
BACKGROUND Knowledge about childhood tuberculosis (TB) in Iran is limited. This study aimed to determine the proportion of tuberculosis in children living in Khuzestan in southwest of Iran and its treatment outcomes. METHODS In this retrospective study, the child's medical records registered in national TB program (NTP) unit of Khuzestan Health Center (KHC) for TB treatment from 2005 to 2010 were studied. Data including demographic, clinical presentation, laboratory test results, and treatment outcomes were extracted from the files and were analyzed. RESULTS Of total 4104 new TB cases registered in KHC, 203 (4.9%) were children. The mean age was 10.7±4.3 years, and 75.7% of them were females. More than 84% of TB children cases were 10 years or older, whereas, young children (< 5 years old) accounted for 5.6%. Of the total studied cases, 57.1% were pulmonary TB and 42.9% were extra pulmonary, 91.7% were successfully treated and 8.3% had poor treatment outcome. The main risk factors for poor treatment outcome were: age <5 years (OR: 0.17, 95% CI, 0.04-0.76), low body weight (OR: 0.08, 95% CI, 0.01-0.60), household contact with cases of TB treatment failure (OR: 0.13, 95% CI, 0.03-0.52), and exposure to cigarette smoke odor inside the home (OR: 0.17, 95% CI, 0.05-0.56). CONCLUSION The proportion of pediatric TB in the region was lower than expected. The treatment success rate was higher than the rate defined in NTP. Special attention should be given to children aged less than five years, low body weight, contact with TB treatment failure cases, and exposure to cigarette smoke.

Abstract
This study investigated the frequency of Escherichia col, Shigella and Salmonella species in stool specimens from patients with diarrhoea presenting to health centres in Hamedan province, Islamic Republic of Iran. From 144 samples, Shigella strains were isolated in 17 cases (11.8%): 10 Sh. flexneri, 3 Sh. sonnei, 2 Sh. boydii and 2 untyped strains. No Salmonella strains were isolated. Using molecular diagnostic methods, diarrheogenic E. coli were detected in 37 cases (25.7%), the majority were enterotoxigenic (ETEC) (22 cases) and Shiga toxin-producing (STEC) strains (15 cases). In 14 cases (9.7%) there was co-infection.
