Comparison of the Effect of 2 Virtual Education Methods: Family-based Versus Peer-Support on Perceived Stress and Stress Coping in Women with Breast Cancer: A Randomized Controlled Trial.

Background: Stress is an overwhelming feeling in patients with breast cancer (BC). However, The effect of virtual education has not been fully regulated. Hence, this study intends to compare the impact of 2 virtual education methods on perceived stress and stress coping in women with BC. Methods: A 3-armed randomized clinical trial was conducted among 315 women with BC who were referred to the Cancer Institute in Tehran. They were randomly assigned to 3 groups: (a) Family-based, receiving family-based training package; (b) peer-support, receiving peer-support educational package; and (c) control, receiving routine hospital care. Data were collected through demographic and disease characteristics, the Perceived Stress Scale (PSS-14), and Coping Inventory for Stressful Situations (CISS-21) questionnaires before and 3 months after the intervention. Results: The effect of the group factor after controlling the before-intervention scores in perceived stress, problem-oriented, emotion-oriented, and avoidance-oriented strategies were P < 0.0001, P = 0.015, P < 0.0001, and P = 0.111, respectively. Also, the effect of the confounding factor of BC disease stage in the dependent variables was P = 0.527, P = 0.275, P = 0.358, and P = 0.609, respectively. The effect size test showed that before the intervention, the mean scores of perceived stress, problem-oriented, emotion-oriented, and avoidance-oriented strategies were 32.00 ± 7.03, 19.36 ± 4.68, 25.10 ± 5.90, and 17.65 ± 6.64 respectively, but after the intervention showed a decrease in mean scores of perceived stress, emotion-oriented, and avoidance strategies. Conclusion: What is vibrant in virtual family-based education is far more effective than peer support when problem-oriented coping increases. Conversely, reducing perceived stress in women with BC receiving enough information and family support should be considered.

Transcriptional alteration of NF-κB-associated long noncoding RNAs in the stomach of Helicobacter pylori-infected and non-infected patients.

INTRODUCTION: Helicobacter pylori could colonize the gastric mucosa and cause gastritis, ulcers and cancer. Numerous virulence factors have been identified in this bacterium that play important roles in promoting gastric disorders. Although the interaction of long noncoding RNAs (lncRNAs) with transcription, processing, and translation of genes associated with different diseases are described, their interaction with the inflammatory genes and H. pylori infection in the gastric tissue is not well known. This study compared changes in common NF-κB-regulatory lncRNAs in the gastric tissue of H. pylori-infected and non-infected patients with gastritis. Moreover, a link between the virulence entity of the strains and the transcriptional changes was analyzed. METHODOLOGY: Two groups of infected and non-infected patients with chronic gastritis were included in the study. Genotyping of the H. pylori strains was done by PCR and relative changes in the expression of NF-κB and regulatory lncRNAs, lincRNA-p21, MALAT1, NKILA, were measured by relative quantitative real time-PCR. RESULTS: Transcriptional levels of MALAT1, lincRNA-p21, and NKILA genes decreased in the infected patients compared with the non-infected patients, which was significantly linked with increased NF-κB gene expression. Our results showed that a hypervirulent strain of H. pylori with oipA"on"/HP-NAP+/iceA1+/iceA2+/vacA s1m1/s1m2+/cagA+ genotype can promote a higher level of NF-κB transcription in the inflamed tissue. CONCLUSIONS: H. pylori infection could promote down-regulation of lincRNA-p21, MALAT1 and NKILA in the infected gastric tissue in correlation with NF-κB upregulation. More detailed studies are needed to show a link between the virulence genes and their impact on the regulation of lncRNAs in the stomach.

Investigating the effect of MAP2K1 gene (MEK1) in MAPK pathway in the induction of adult T-cell leukemia/lymphoma (ATLL).

Background and Objectives: HTLV-1 is responsible for two important diseases, HAM/TSP and ATLL. Approximately 10 to 20 million people are infected with HTLV-1 worldwide. Identifying altered genes in different cancers is crucial for finding potential treatment strategies. One of the proteins of the RAS/MAPK signaling pathway is MEK1, which is made from the MAP2K1 gene. The effects of the MAP2K1 gene on the MAPK signaling pathway are not yet fully elucidated. The current study aims to determine the MAP2K1 gene mutations and the level of MAP2K1 gene expression in ATLL patients compared to healthy individuals. Materials and Methods: Ten ATLL and 10 healthy control individuals were investigated in this study. We used ELISA test to screen anti-HTLV-I antibodies and PCR for confirmation of infection. Then, we extracted total RNA from fresh whole blood, and cDNA was synthesized. The expression levels of the MAP2K1 gene were examined by qRT-PCR, and to check possible mutations in the MAP2K1 gene; all samples were sequenced and analyzed by BioEdite Software. Results: MAP2K1 gene expression in the ATLL group was significantly higher than in the healthy control (P=0.001). The mutational sequencing analysis showed nucleotide 212 (S→R) change and identification mutations at different nucleotides that were entirely different from the nucleotide mutations defined in the UniProt database. Conclusion: These results could be a perspective in the prevention, prognosis, and targeted treatment of diseases in which the MAP2K1 gene plays a vital role.

Phylogenetic characterization of rhinovirus and adenovirus in hospitalized children aged ≤ 18 years with severe acute respiratory infection in Iran.

Background and Objectives: Human rhinoviruses (HRVs) and human adenoviruses (HAdVs) are among the most prevalent viruses in hospitalized patients with severe acute respiratory infection (SARI). This study aimed to evaluate the molecular characterization of HRV and HAdV in hospitalized patients with SARI, who aged ≤ 18 years in Tehran, Iran. Materials and Methods: To detect these two viruses, a conventional nested RT-PCR (Reverse transcription-polymerase chain reaction) assay was performed on 264 throat swabs collected from December 2018 to March 2019. The epidemiological data were analyzed and phylogenetic trees were constructed. Results: Of 264 cases with SARI, 36 (13.6%) and 28 (10.6%) were positive for HAdV and HRV respectively. Of 21 HRV sequenced samples, HRV-A (42.9%), HRV-B (9.5%) and HRV-C (47.6%) and of 36 HAdV sequenced samples, HAdV-C6 (38.9%), HAdV-B7 (22.2%), HAdV-B3 (11.1%), HAdV-B16 (5.6%), HAdV-C5 (13.9%), HAdV-C57 (5.6%), HAdV-E4 (2.8%); were detected in children with SARI. Some viral genotypes appeared to cause more severe disease, which may lead to hospitalization. Conclusion: Large-scale studies are recommended to investigate the epidemiology and molecular characterizations through surveillance networks to provide useful information on etiology, seasonality, and demographic associations in patients with SARI.

Post-surgery Survival in Patients with Adenocarcinoma of Stomach Using Multistate Model.

PURPOSE: Stomach neoplasms are the fifth common cancer worldwide. The related factors for survival following stomach neoplasms are well-studied; however, information on recurrent events is limited. This study aimed to identify the related factors on recurrent and deaths following stomach neoplasms. METHODS: In this cohort study, information on 672 patients with adenocarcinoma who were hospitalized during 1995-2012 was used. Multistate models were applied to determine the effective factors on recurrent and death events. RESULTS: Median of survival time (months) and 5-year survival was estimated as 24.5 and 25%, respectively. The probability of death was 57% for non-recurrent patients, which increased to 88% among recurrent patients. Hazard of death was 49% lower for females (Hazard Ratio (HR):0.51, P = 0.009) while females had higher hazard of death following recurrent (HR:3.55, P < 0.001). Male patients and those with cardia involvement had higher risk of recurrence. A significant effect of age on the risk of death among patients with and without recurrence was estimated (HR:1.02, 1.03; P = 0.001 for both). Age, cardia involvement, and disease stage are amongst the effective factors on non-recurrent death while complement treatments increased the non-recurrent and recurrent survival. CONCLUSION: In patients, effects of some factors for survival may vary throughout the course of disease and depend on recurrence status. We found that while female patients experienced lower recurrence, they had higher risk of death following recurrence. Age, tumor location, and type of therapy were risk factors for non-recurrent death. Finally, tumor location and type of surgery had significant effects on recurrence.

Network meta-analysis of palliative treatments in patients with esophageal cancer.

We aimed to compare available palliative treatments in terms of survival and to rank these treatments for esophageal cancer. Web of Science, Medline, Scopus, Cochrane Library and Embase were searched. The risk of bias was judged using Cochrane's tools. Statistical heterogeneity was assessed using the Chi2 test and was quantified by I2. The results were summarized using the hazard ratio (HR). The rank probability for each treatment was calculated using the p-score. Nineteen RCTs met the eligibility criteria for this study. Treatments formed three networks including networks A, B, and C. The Ultraflex stent (p-score = 0.93), irradiation stent (p-score = 0.89), and thermal ablative therapy (p-score = 0.85) were the first ranking treatments in networks A, B, and C, respectively. Based on the results of this network meta-analysis, it appears that the ultraflex stent, the irradiation stent, and thermal ablative therapy are the better treatments among the networks.

A Mycological and Molecular Epidemiologic Study on Onychomycosis and Determination In Vitro Susceptibilities of Isolated Fungal Strains to Conventional and New Antifungals.

Background: Onychomycosis is one of the most common and recurrent dermatological diseases worldwide. The antimycotic activity of prescribed medications varies according to the causative agents, and treatment failure rates exceeding 30%. This study aimed to assess the epidemiological profile of onychomycosis in Iran. Also, the susceptibilities to conventional and new antifungals were investigated. Methods: In this descriptive cross-sectional study, during the period of 18 months starting from September 2019 until March 2020, 594 nail specimens were obtained from patients who presented nail changes compatible with a clinical diagnosis of onychomycosis. The patients were referred from different cities, including Tehran, Kermanshah, Arak, Kashan, Rasht, Qom, Urmia, Zahedan, Hamadan, Zanjan, Borujerd, Bushehr, and Yazd. All the samples were subjected to microscopic examination and fungal culture. Fungi identified were confirmed through the PCR-sequencing method. The susceptibility to itraconazole, fluconazole, terbinafine, griseofulvin, posaconazole, ravuconazole, efinaconazole, luliconazole, and tavaborole was evaluated according to the Clinical and Laboratory Standards Institute (CLSI) guidelines, document M38-A2 for filamentous fungi, and document M27-A3 for yeasts. Results: 594 patients were included. Of these, in 179 cases (30.1%) (95% CI:0.3 ± 0.037) onychomycosis was confirmed. The majority of patients were ≥ 60 years of age (n=58, 32.6%) and female (n=113, 63.1%). Saprophytic fungi accounted for the vast majority of the nail isolates (n=92, 51.4%) (95% CI:0.051 ± 0.0.073), followed by dermatophytes (n=45, 25.1%) (95% CI:0.25 ± 0.063), and yeasts (n=42, 23.5%) (95% CI:0.23 ± 0.061). Diabetes mellitus (77.3%), hypothyroidism (18.2%), and solid tumors (4.5%) were documented as the most prevalent underlying conditions. Antifungal susceptibility testing was performed against 60 fungal isolates (20 each of Candida species, saprophytic fungi, and dermatophytes). Efinaconazole, ravuconazole, and luliconazole were the most active agents against Candida species. Also, luliconazole, posaconazole, and efinaconazole were most potent against dermatophytes. Luliconazole had the greatest antifungal activity against saprophytic fungi. Conclusions: The prevalence of onychomycosis in Iranian patients was relatively high. LUL exhibited potent antifungal activity against the three groups of fungi tested, determining its broad-spectrum antimycotic activity and its probable use as the first-line therapy for onychomycosis.

Transcriptional alteration of genes linked to gastritis concerning Helicobacter pylori infection status and its virulence factors.

BACKGROUND: Helicobacter pylori infection and heterogeneity in its pathogenesis could describe diversity in the expression of inflammatory genes in the gastric tissue. We aimed to investigate transcriptional alteration of genes linked to gastritis concerning the H. pylori infection status and its virulence factors. METHODS AND RESULTS: Biopsy samples of 12 infected and 12 non-infected patients with H. pylori that showed moderate chronic gastritis were selected for transcriptional analysis. Genotyping of H. pylori strains was done using PCR and relative expression of inflammatory genes was compared between the infected and non-infected patients using relative quantitative real-time PCR. Positive correlations between transcriptional changes of IL8 with TNF-α and Noxo1 in the infected and TNF-α with Noxo1, MMP7, and Atp4A in the non-infected patients were detected. Six distinct genotypes of H. pylori were detected that showed no correlation with gender, ethnicity, age, endoscopic findings, and transcriptional levels of host genes. Irrespective of the characterized genotypes, our results showed overexpression of TNF-α, MMP7, Noxo1, and ATP4A in the infected and IL-8, Noxo1, and ATP4A in the non-infected patients. CONCLUSIONS: A complexity in transcription of genes respective to the characterized H. pylori genotypes in the infected patients was detected in our study. The observed difference in co-regulation of genes linked to gastritis in the infected and non-infected patients proposed involvement of different regulatory pathways in the inflammation of the gastric tissue in the studied groups.

Treatment-related complications in patients with esophageal cancer: A systematic review and network meta-analysis.

BACKGROUND: The aim of this review was to compare the available treatments of esophageal cancer, in terms of pulmonary, cardiovascular complications, anastomotic leakage, and esophagitis after treatment in patients with esophageal squamous cell carcinoma (SCC). METHODS: Medline, Web of Science, Scopus, the Cochrane Library and Embase were searched. The randomized controlled trials (RCT) that had compared the treatment -related complications of treatments for esophageal SCC were included. We included 39 randomized control trials in a network meta-analysis. The Chi2-test was used to assess of heterogeneity. The loop-specific and design-by-treatment interaction methods were used for assessment of consistency assumption. The risk ratio with 95% confidence interval (CI) was used to report the effect-sizes in the network meta-analysis. RESULTS: The pulmonary complication, cardiac complication, anastomotic leakage, and esophagitis were reported in 31, 11, 17, and 15 RCTs respectively. Video-assisted thoracoscopy + laparoscopy (VATS) was rank as the first and second treatment in terms of lower risk for pulmonary complication and anastomotic leakage. There was no statistically significant difference between treatments in terms of lower risk of cardiovascular complications. However, Surgery + Cisplatin + Fluorouracil (SCF) was ranked as better treatment. 3-dimensional conformal radiotherapy + Docetaxel + Cisplatin (3DCRTDC) was the best treatment in terms of lower risk for esophagitis. CONCLUSION: According to the results of this study, it seems the risk of pulmonary, cardiovascular, anastomotic leakage and esophagitis complications for VATS, SCF, surgery + radiotherapy (SRT), and 3DCRTDC was lower than other treatments respectively in the networks.

Phylogenetic and phylodynamic study of Human T-cell lymphotropic virus Type 1 (HTLV-1) in Iran.

Human T-lymphotropic virus type-1 (HTLV-1) is a retrovirus that causes the neurological disorder HTLV-1 associated myelopathy/ tropical spastic paraparesis (HAM/TSP) and/or adult T-cell leukemia/lymphoma (ATLL). Iran is one of the endemic regions of the HTLV-1 in the Middle East. To infer the origin of the virus in Iran and to follow the movements of human population and routes of virus spread to this country, phylogenetic and phylodynamic analyses were performed. To this purpose, the long terminal repeat (LTR) region of HTLV-1 was used. New LTR sequences were obtained from 100 blood samples which infected with HTLV-1. Moreover, all Iranian LTR sequences which have been reported so far, were obtained from GenBank database. Sequences were aligned and maximum-likelihood and Bayesian tree topologies were explored. After identification of Iranian specific cluster, molecular-clock and coalescent models were used to estimate time to the most recent common ancestor (tMRCA). Bayesian Skyline Plots (BSP), representing population dynamics HTLV-1 strains back to the MRCA, were estimated using BEAST software. Phylogenetic analysis demonstrated that the Iranian, Kuwaiti, German, Israelite and southern Indian isolates are located within the widespread "transcontinental" subgroup A clade of HTLV-1 Cosmopolitan subtype a. Molecular clock analysis of the Iranian cluster dated back their respective tMRCA to be 1290 AC with a 95% HPD confidence intervals (918, 1517). BSPs indicated a rapid exponential growth rate in the effective number of infections prior the 15th century. Our results support the hypothesis of a multiple introductions of HTLV-1 into Iran with the majority of introductions occurring in prior the 15th century, at the same time the Mongol invasion of Iran. Our results further suggest that HTLV-1 introduction into Iran was facilitated by the commercial/migratory linkage as known as the ancient Silk Road which linked China to Antioch (now in Turkey).

Association of body mass index and waist circumference with osteocalcin and C-terminal telopeptide in Iranian elderly: results from a cross-sectional study.

There is no agreement on the role of obesity as a protection or unfavorable factor on bone. In the present study, the association of body mass index (BMI) and waist circumference (WC) with osteocalcin, C-terminal telopeptide of type 1 collagen (CTX-I), highly sensitive C-reactive protein (hs-CRP), parathormon (PTH) and 25-hydroxyvitamin D (25(OH)D) in elderly people was investigated. This cross-sectional study was conducted on 178 elderly residents in Tehran, with a mean age of 67.04 (60-83). Serum osteocalcin, hs-CRP, 25(OH) D, PTH and urine CTX-I were measured for all participants. Waist circumference, weight and height were measured and BMI was calculated. Linear regression and Pearson correlation were performed to evaluate the relation of BMI and waist circumference with other variables. A significant inverse association was found between BMI with osteocalcin (ß = - 0.171, p = 0.027) after control for covariates. In addition, there were a significant relation of BMI and WC with hs-CRP (ß = 0.246, p = 0.002 and ß = 0.219, p = 0.006, respectively) and PTH (ß = 0.1169, p = 0.040 and ß = 0.200, p = 0.018), respectively. The present study did not show a significant relation of BMI and WC with urine CTX-I even after adjustment for potential confounders (ß = - 0.143, p = 0.065 and ß = - 0.104, p = 0.183, respectively). The present study has concluded that obesity is an undesirable factor for bone metabolism by reducing serum osteocalcin and by increasing hs-CRP and PTH which contribute to bone resorption.

A Spatial Survival Model in Presence of Competing Risks for Iranian Gastrointestinal Cancer Patients

Background: Gastrointestinal cancer is one of the common causes of death from cancer in Iran. Survival analysis is usually used to detect prognostic factors of time to death from gastrointestinal cancers. The use of ordinary survival models, in the presence of competing risks and/or when data is collected within geographic areas, may lead to distorting the results. Therefore, the aim of this study is to use the spatial survival models in the presence of competing risks to assess the risk factors affecting the survival time of gastrointestinal cancer patients. Methods: The data in this study was collected from 602 patients who were diagnosed with gastrointestinal cancer in Golestan and Mazandaran provinces registered in Iran's National Institute of Health Research from 2002 through 2007 and were followed up to July 2017. The data was analyzed using the cause-specific hazard frailty model with multivariate conditional autoregressive distribution for frailties in the presence of competing risks (death from gastrointestinal cancer, heart disease, and other causes) via OpenBUGS software. Results: The hazard of death from gastrointestinal cancer in men patients, patients who lived in rural areas, patients whose relatives did not have a history of cancer, patients who did not undergo surgery, and patients with gastric cancer was significantly higher than others. Based on the deviance information criterion (DIC), frailty models and spatial frailty models seemed better than no-frailty model and non-spatial frailty model, respectively. Conclusions: This study showed that the use of the spatial frailty term in the model helps better fit the model. Also, the spatial pattern in the figures suggests the necessity of presence of some still missing, spatially varying covariates relevant for time to death from gastrointestinal cancer, heart disease, or other causes.

A network meta-analysis of the treatments for esophageal squamous cell carcinoma in terms of survival.

We aimed to compare treatments for patients with esophageal squamous cell carcinoma (SCC) in terms of survival. Medline, Web of Science, Scopus, the Cochrane Library and Embase were searched. Randomized controlled trials (RCT) that had compared esophageal SCC treatments were included. The hazard ratio (HR) with 95% credible interval (CrI) was used to summarize the effect measures in the Bayesian network meta-analysis. Out of 23,256 references, 43 RCTs with 34 treatments were included. Carboplatin and paclitaxel plus radiotherapy plus surgery (carbo-pacli + RT + S) compared with surgery alone decreased risk of death (HR = 0.49; 95% CrI: 0.26, 0.90). The HRs for carbo-pacli + RT + S versus surgery plus cisplatin and fluorouracil and surgery plus cisplatin and vindesine were 0.44 (0.22, 0.86) and 0.41 (0.20, 0.83), respectively. Among all treatments in network, carbo-pacli + RT + S ranked as first treatment. It seems carbo-pacli + RT + S was a better treatment among available treatments in network in terms of survival in patients with esophageal SCC.

Long-Term Disease-Free Survival of Non-Metastatic Breast Cancer Patients in Iran: A Survival Model with Competing Risks Taking Cure Fraction and Frailty into Account

Introduction: Survival modeling is a very important tool to detect risk factors and provide a basis for health care planning. However, cancer data may have properties leading to distorted results with routine methods. Therefore, this study aimed to cover specific factors (competing risk, cure fraction and heterogeneity) with a real dataset of Iranian breast cancer patients using a competing risk-cure-frailty model. Materials and methods: For this historical cohort study, information for 550 Iranian breast cancer patients who underwent surgery for tumor removal from 2001 to 2007 and were followed up to March 2017, was analyzed using R 3.2 software. Results: In contrast to T-stage and N-stage, hormone receptor status did not have any significant effect on the cure fraction (long-term disease-free survival). However, T-stage, N-stage and hormone receptor status all had a significant effect on short-term disease-free survival so that the hazard of loco-regional relapse or distant metastasis in cases positive for a hormone receptor was only 0.3 times that for their negative hormone receptor counterparts. The likelihood of locoregional relapse in the first quartile of follow up was nearly twice that of other quartiles. The least cumulative incidence of time to locoregional relapse was for cases with a positive hormone receptor, low N stage and low T stage. The effect of frailty term was significant in this study and a model with frailty appeared more appropriate than a model without, based on the Akaike information criterion (AIC); values for the frailty model and one without the frailty parameter were 1370.39 and 1381.46, respectively. Conclusions: The data from this study indicate ae necessity to consider competing risk, cure fraction and heterogeneity in survival modeling. The competing risk-cure-frailty model can cover complex situations with survival data.

Complications of stent placement in patients with esophageal cancer: A systematic review and network meta-analysis.

BACKGROUND: Palliative treatments and stents are necessary for relieving dysphagia in patients with esophageal cancer. The aim of this study was to simultaneously compare available treatments in terms of complications. METHODS: Web of Science, Medline, Scopus, Cochrane Library and Embase were searched. Statistical heterogeneity was assessed using the Chi2 test and was quantified by I2. The results of this study were summarized in terms of Risk Ratio (RR). The random effects model was used to report the results. The rank probability for each treatment was calculated using the p-score. RESULTS: Out of 17855 references, 24 RCTs reported complications including treatment related death (TRD), bleeding, stent migration, aspiration, severe pain and fistula formation. In the ranking of treatments, thermal ablative therapy (p-score = 0.82), covered Evolution® stent (p-score = 0.70), brachytherapy (p-score = 0.72) and antireflux stent (p-score = 0.74) were better treatments in the network of TRD. Thermal ablative therapy (p-score = 0.86), the conventional stent (p-score = 0.62), covered Evolution® stent (p-score = 0.96) and brachytherapy (p-score = 0.82) were better treatments in the network of bleeding complications. Covered Evolution® (p-score = 0.78), uncovered (p-score = 0.88) and irradiation stents (p-score = 0.65) were better treatments in network of stent migration complications. In the network of severe pain, Conventional self-expandable nitinol alloy covered stent (p-score = 0.73), polyflex (p-score = 0.79), latex prosthesis (p-score = 0.96) and brachytherapy (p-score = 0.65) were better treatments. CONCLUSION: According to our results, thermal ablative therapy, covered Evolution® stents, brachytherapy, and antireflux stents are associated with a lower risk of TRD. Moreover, thermal ablative therapy, conventional, covered Evolution® and brachytherapy had lower risks of bleeding. Overall, fewer complications were associated with covered Evolution® stent and brachytherapy.

Cardamom supplementation improves inflammatory and oxidative stress biomarkers in hyperlipidemic, overweight, and obese pre-diabetic women: a randomized double-blind clinical trial.

BACKGROUND: Several preclinical studies have shown that spices may decrease the risk of chronic diseases. However, it has been suggested that more clinical trials be carried out to strengthen this preclinical evidence. The purpose of the present study was to evaluate the effects of cardamom (Elettaria cardamomum) supplementation on inflammation and oxidative stress in hyperlipidemic, overweight, and obese pre-diabetic women. METHODS: This randomized, placebo-controlled, double-blind clinical trial was conducted on 80 pre-diabetic subjects. They randomly received the cardamom supplement (n = 40, 3 g d-1 ) or identical inert placebo (n = 40) for 8 weeks. Serum concentrations of high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), tumour necrosis factor α, total antioxidant capacity, malondialdehyde (MDA), protein carbonyl, and erythrocyte superoxide dismutase and glutathione reductase activity were analyzed at the baseline and after intervention. RESULTS: After the adjustment of some covariates, cardamom supplementation significantly decreased serum hs-CRP (P = 0.02), hs-CRP:IL-6 ratio (P = 0.008), and MDA (P = 0.009) compared with the placebo group. CONCLUSION: Cardamom could improve some parameters of inflammation and oxidative stress in pre-diabetic subjects. Thus it may be useful in reducing complications associated with inflammation and oxidative stress in these patients.

17-alpha-hydroxyprogesterone caproate versus vaginal progesterone suppository for the prevention of preterm birth in women with a sonographically short cervix: A randomized controlled trial.

AIM: The aim of this study was to compare 17-alpha-hydroxyprogesterone caproate (17OHP-C) with vaginal progesterone suppository for the prevention of preterm birth in women with a sonographically short cervix and to evaluate the changes of the cervical length (CL) over time. METHODS: In this prospective randomized controlled trial, eligible patients were asymptomatic pregnant women with a sonographically short cervix. The participants in group 1 (n = 147) received vaginal progesterone suppositories at a dose of 400 mg daily and the women in group 2 (n = 150) received an i.m. dose of 250 mg 17OHP-C once a week. Transvaginal sonography was repeated every 3 weeks until 36 gestational weeks or the occurrence of preterm labor. RESULTS: A total of 304 singleton pregnant women between 16 and 24 gestational weeks with CL < 25 mm were enrolled in our study. The rates of preterm birth were 10.4% in the progesterone group and 14% in the 17OHP-C group: a difference that was not statistically significant (P = 0.416). Moreover, 264 participants underwent ultrasound examination five times and CL changes were studied for 15 weeks. The results showed that the CL changes over 15 weeks were statistically significant (P < 0.001), but the method of intervention (progesterone/17OHP-C) had no significant effect on CL change (P = 0.64). CONCLUSION: Our findings showed that vaginal progesterone and 17OHP-C had the same effect on the risk of preterm labor in asymptomatic women with a sonographically short cervix. We detected no significant difference between the effect of 17OHP-C and vaginal progesterone on CL changes over time.

The Effect of Quercetin on Inflammatory Factors and Clinical Symptoms in Women with Rheumatoid Arthritis: A Double-Blind, Randomized Controlled Trial.

OBJECTIVE: Previous studies have shown that the bioflavonoid quercetin has anti-inflammatory and anti-nociceptive effects. We investigated the effect of quercetin supplementation on inflammation, disease severity, and clinical symptoms in women with rheumatoid arthritis (RA). METHODS: The present study was a randomized, double-blind, placebo-controlled clinical trial in which 50 women with RA were allocated into a quercetin (500 mg/day) or placebo group for 8 weeks. Plasma levels of high-sensitivity tumor necrosis factor-α (hs-TNFα), erythrocyte sedimentation rate (ESR), clinical symptoms including early morning stiffness (EMS), morning and after-activity pain, and tender (TSC) and swollen joint counts (SJC) were determined. Disease activity and functional disability were assessed by Disease Activity Score 28 (DAS-28), physician global assessment (PGA), and a health assessment questionnaire (HAQ) at the beginning and end of the study. RESULTS: Quercetin supplementation for 8 weeks significantly reduced EMS, morning pain, and after-activity pain (p < 0.05). DAS-28 and HAQ scores decreased in the quercetin group compared to placebo and the number of patients with active disease significantly decreased in the quercetin group. Plasma hs-TNFα level was significantly reduced in the quercetin group compared to placebo (p < 0.05). There were no significant differences in TJC and SJC between groups but TJC significantly decreased in the quercetin group after the intervention. Supplementation had an effect on ESR but it was not significant (p > 0.05). CONCLUSIONS: Five hundred milligrams per day quercetin supplementation for 8 weeks resulted in significant improvements in clinical symptoms, disease activity, hs-TNFα, and HAQ in women with RA.

Prognostic value of on admission arterial PCO2 in hospitalized patients with community-acquired pneumonia.

BACKGROUND: There is little data about the correlation between the outcome of community acquired pneumonia (CAP) and the hypercapnic type respiratory failure. In this study we prospectively investigated the prognostic significance of first arterial CO2 tension in patients hospitalized with CAP. METHODS: In this prospective study patients with CAP, admitted to a general hospital were included. PaCO2 was measured for each subject in an arterial blood sample drawn in the first 2 hours and its correlations with three major outcomes were evaluated: intensive care unit (ICU) admission, duration of admission and mortality in 30 days. RESULTS: A total of 114 patients (mean age: 60.9±18.3; male: 51.8%) diagnosed with CAP were included. Significant relationship was not found between PaCO2 and mortality (P=0.544) or ICU admission (P=0.863). However advanced age, associated CHF, high BUN levels, high CURB-65 scores, associated pleural effusion in chest X-ray and being admitted to the ICU (P=0.012, 0.004, 0.003, <0.001, 0.045 and <0.001 respectively) were all significant prognostic factors of higher mortality risks. Prognostic factors for ICU admission were a history of malignancy (P=0.004), higher CURB-65 (P<0.001) scores and concomitant pleural effusion (P=0.028) in chest X-ray. Hypercapnic patients hospitalized for longer duration compared with normocapnic subjects. Furthermore, patients with lower pH (P=0.041) and pleural effusions (P=0.002) were hospitalized longer than the others. CONCLUSIONS: There was less prominent prognostic value regarding on-admission PaCO2 in comparison to other factors such as CURB-65. Considering the inconsistent results of surveys conducted on prognostic value of PaCO2 for CAP outcomes, further investigations are required to reach a consensus on this matter.

Relationship between' patient's rights charter' and patients' satisfaction in gynecological hospitals.

BACKGROUND: Patient's satisfaction with hospital services is one of the most important indicators of efficiency and quality of services of different hospital wards. METHODS: This cross-sectional descriptive analytical study was conducted in 2015. The study population included patients in gynecological hospitals of TUMS, and by using questionnaires; data were collected from 304 patients. Statistical analysis was performed using the SPSS 22. RESULTS: The rights of patients were mainly observed through "quality of care" (Mean ± SD: 9.65 ± 2.62), "knowing the charges and the right to complain"; (Mean ± SD: 6.00 ± 2.5) "presence of an active system to handle complaints of patients in the hospital and explanation of the error that occurred during service provision to patients by the wrongdoer" is the lowest (7.5 ± 2.62). It was found that patients' satisfaction is below the mean and its different aspects are higher than the mean level. However, the services of physicians and feeding recorded the highest and lowest satisfaction, respectively (19.4 ± 4.25, 20.77 ± 4.39). The mean score of satisfaction of patients admitted with nursing physical care was 24.5 ± 6.2. CONCLUSION: Overall, patients' satisfaction with hospital services was close to the mean. Deficiencies and grievances should be resolved with a correct measure.
