ABSTRACT
BACKGROUND: Inflammatory bowel disease (IBD) imposes a huge burden on the healthcare systems and greatly declines the patient's quality of life. However, there is a paucity of detailed data regarding information and supportive needs as well as sources and methods of obtaining information to control different aspects of the disease from the perspectives of the patients themselves. This study aimed to establish the IBD patients' preferences of informational and supportive needs through Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA). METHODS: IBD patients were recruited from different centers. Considering inclusion and exclusion criteria, 521 participants were filled a predefined questionnaire. This questionnaire was prepared through literature review of the recent well-known guidelines on the needs of IBD patients, which was further approved by the experts of IBD area in three rounds of Delphi consensus. It includes 56 items in four sections of informational needs (25), supportive needs (15), sources of information (7), and methods of obtaining information (9). RESULTS: In particular, EFA was used to apply data reduction and structure detection. Given that this study tries to identify patterns, structures as well as inter-relationships and classification of the variables, EFA was utilized to simplify presentation of the variables in a way that large amounts of observations transform into fewer ones. Accordingly, the EFA identified five factors out of 25 items in the information needs section, three factors out of 15 items in the supportive needs section, two factors out of 7 items in the information sources section, and two factors out of 9 items in the information presentation methods. Through the CFA, all 4 models were supported by Root Mean Squared Error of Approximation (RMSEA); Incremental Fit Index (IFI); Comparative Fit Index (CFI); Tucker-Lewis Index (TLI); and SRMR. These values were within acceptable ranges, indicating that the twelve factors achieved from EFA were validated. CONCLUSIONS: This study introduced a reliable 12-factor model as an efficient tool to comprehensively identify preferences of IBD patients in informational and supportive needs along with sources and methods of obtaining information. An in-depth understanding of the needs of IBD patients facilitates informing and supporting health service provision. It also assists patients in a fundamental way to improve adaptation and increase the quality of life. We suggest that health care providers consider the use of this tool in clinical settings in order to precisely assess its efficacy.

Background: The present study introduces informational and supportive needs and sources of obtaining information in patients with inflammatory bowel disease (IBD) through a three-round Expert Delphi Consensus Opinions method. Methods: According to our previous scoping review, important items in the area of informational and supportive needs and sources of obtaining information were elucidated. After omitting duplicates, 56 items in informational needs, 36 items in supportive needs, and 36 items in sources of obtaining information were retrieved. Both open- and close-ended questions were designed for each category in the form of three questionnaires. The questionnaires were sent to selected experts from different specialties. Experts responded to the questions in the first round. Based on the feedback, questions were modified and sent back to the experts in the second round. This procedure was repeated up to the third round. Results: In the first round, five items from informational needs, one item from supportive needs, and seven items from sources of obtaining information were identified as unimportant and omitted. Moreover, two extra items were proposed by the experts, which were added to the informational needs category. In the second round, seven, three, and seven items from informational needs, supportive needs, and sources of obtaining information were omitted due to the items being unimportant. In the third round, all the included items gained scores equal to or greater than the average and were identified as important. Kendall coordination coefficient W was calculated to be 0.344 for information needs, 0.330 for supportive needs, and 0.325 for sources of obtaining information, indicating a fair level of agreement between experts. Conclusions: Out of 128 items in the first round, the omission of 30 items and the addition of two items generated a 100-item questionnaire for three sections of informational needs, supportive needs, and sources of obtaining information with a high level of convergence between experts' viewpoints.
ABSTRACT
Introduction: Epstein-Barr Virus (EBV)-associated gastric cancer is a distinct molecular subtype of gastrointestinal carcinomas as defined by the Cancer Genome Atlas. Methods: In the present study 237 samples from Iranian patients diagnosed with gastric cancer and gastroduodenal disease were retrospectively examined for EBV infection by quantitative Real-Time PCR. Results: Of the 237 samples tested, EBV DNA was detected in 37 samples (15.6%), in 13 of the 81 gastric cancer cases (16%), and 24 of the 156 non-cancerous samples (15.4%). The EBV infection rate was found higher in patients with gastric ulcer (35%) and duodenal ulcer (21.9%) compared to patients with gastric cancer (16%) and gastritis (19.6%). The EBV-encoded small RNA (EBER) copy number in the gastric cancer group (mean = 2.14×10-1 with range of 2.14×10-2 to 4.10×10-1 copies/ cell) was higher than gastroduodenal diseases group (mean = 1.39×10-2 with range 1.11×10-3 to 2.35×10-2 copies/ cell), and this difference was statistically significant (P >0.001). Conclusion: The higher number of copies of EBV-EBER in the gastric cancer group compared to the non-cancer group confirmed the possible role of EBV in inducing cancer.
ABSTRACT
BACKGROUND@#Bloating is a common gastrointestinal complaint which is difficult to treat.@*OBJECTIVE@#This study investigated the efficacy and compliance of a formulation called KAASER comprised of Trachyspermum ammi (L.) Sprague seed, Zingiber officinale Roscoe. rhizome and Piper nigrum L. berry in the treatment of functional bloating.@*DESIGN, SETTING, PARTICIPANTS AND INTERVENTION@#A total of 106 patients with functional bloating, between 20 and 50 years of age, participated in this double-blind randomized controlled trial. Patients were divided into 3 parallel groups that received 500 mg of placebo, dimethicone or KAASER, three times a day for 2 weeks.@*MAIN OUTCOME MEASURES@#The frequency and severity of bloating were primary outcomes, while the frequencies of eructation, defecation, borborygmus and early satiation were secondary outcomes. All parameters were evaluated at the beginning (week 0), and also weeks 2, 4 and 10 of the study, through self-report checklists with a scoring system.@*RESULTS@#Among the 84 patients who completed the study, the frequency and severity of bloating (P < 0.001), the frequencies of eructation, defecation and borborygmus (P = 0.03) were significantly improved in the group receiving KAASER (36 patients) compared with the dimethicone (35 patients) and placebo (35 patients) groups, during the 3 phases of follow-up. These significant differences persisted through the 2 and 8 weeks of follow-ups after cessation of medication (week 4 and 10). In early satiation, no significant differences were observed among the 3 groups.@*CONCLUSION@#The results showed that KAASER can be effectively used to treat patients suffering from bloating. Bloating, eructation, defecation and borborygmus in the KAASER group remained significantly improved after 2 and 8 weeks of cessation of medication, making this mechanism an interesting area for further investigation.@*TRIAL REGISTRATION@#Registration trial IRCT2015100324327N on Iranian Registry of Clinical Trials.
ABSTRACT
BACKGROUND: Deficiency of vitamin D has been reported in patients with many types of musculoskeletal pain. The present study was designed to determine the association between serum 25-hydroxyvitamin D [25-(OH)D] deficiency and nonspecific skeletal pain. METHODS: A total of 276 patients with nonspecific skeletal pain at different regions of the skeletal system diagnosed as leg pain, widespread pain, arthralgia, rib pain, back pain and fibromyalgia were compared with 202 matched controls with regard to mean serum 25-(OH)D level and 25-(OH)D deficiency. Serum 25-(OH)D was measured by enzyme-linked immunosorbent assay method and levels < 20 ng/mL were considered as deficient. Nonparametric one-way analysis of variance, Kruskal Wallis and Wilcoxon tests were used for group comparisons. Multiple logistic regression analysis with calculation of adjusted odds ratio (OR) and 95% confidence interval (95% CI) were performed to determine associations. RESULTS: In patients with nonspecific skeletal pain the mean 25-(OH)D was significantly lower (P = 0.0001) and the proportion of 25-(OH)D deficiency was significantly higher (63.4%vs. 36.1%, P = 0.0001) compared with controls. There was a significantly positive association between 25-(OH)D deficiency and skeletal pain (OR = 2.94, 95% CI = 1.01-4.3, P = 0.0001). The strength of association varied across the groups with strongest association observed with leg pain (OR = 7.4; 95% CI = 3.9-13.9, P = 0.0001) followed by arthralgia (OR = 3.9, 95% CI = 2.1-7.1, P = 0.0001) and widespread pain (OR = 2.8, 95% CI = 1.1-6.6, P = 0.020) but no association with back pain and fibromyalgia. There was a greater positive associations in women compared with men (OR = 2.1, 95% CI = 1.1-4.3, P = 0.001). CONCLUSION: The results of this study indicate a positive association of vitamin D deficiency with a variety of nonspecific bone pain, particularly in women. More studies with larger samples are required to confirm these findings. Increasing serum vitamin D to sufficient levels and longitudinal follow-up of patients may provide further evidence in relation to vitamin D deficiency and skeletal pain.
