The effect of diabetes training through social networks on metabolic control of individuals with type 2 diabetes; a randomized controlled trial.

Background: Due to spread of smart phones, opportunity to train patients with diabetes and communicate with them using social media is rising. Aim of this study was to evaluate the effect of training through two popular social networks in Iran ("Telegram" and "Soroush") and the metabolic control of people with Type 2 diabetes. Methods: In this randomized controlled trial, we recruited 134 patients with type 2 diabetes, which randomly allocated into two groups: the intervention and the control group on a 1:1 basis. The studied tools included demographic information and awareness of diabetes and international physical activity questionnaires. The intervention comprised a training package that delivered to the intervention group via social media for 45 days. The primary outcome measures included awareness of diabetes management and physical activity level while secondary outcome measures were HbA1c and lipid profile. Results: Social network training led to the increase of the patients' awareness (44.31 ± 2.78 to 46.88 ± 2.25 in intervention group vs 44.14 ± 3.85 to 44.41 ± 3.87 in control group) and physical activities level (23.64 ± 8.46 to 31.68 ± 7.12 in intervention group vs 26.20 ± 9.39 to 30.20 ± 8.11 in control group) (p-value < 0.001). Besides, LDL and HDL levels, and HbA1c (8.19 ± 2.10 to 8.05 ± 1.96 in intervention group vs. 7.53 ± 1.67 to 7.45 ± 1.34 in control group) decreased significantly (p-value < 0.05). Conclusions: Changes in lifestyle and challenges of the patients' attendance in diabetes training sessions, declared that use of social networks can be useful to train diabetes patients remotely, and it is feasible to send training messages to help them improve their diabetes care.

Effect of atorvastatin on delirium status of patients in the intensive care unit: a randomized controlled trial.

INTRODUCTION: Delirium is one of the most prevalent complications in intensive care unit (ICU) patients, which is related to worse clinical outcomes including a longer ICU stay, longer duration of mechanical ventilation, higher mortality rates and increased risk of cognitive impairment. Observational studies have suggested that statins might have a positive effect on delirium status of hospitalized patients. To date, there has been no trial assessing the effect of atorvastatin on delirium status in critically ill patients. Thus, the aim of the current study was to determine the efficacy of atorvastatin on delirium status of patients in the ICU. METHODS: In this randomized, double-blind and controlled trial, a total of 90 patients in the general ICU who had delirium for at least 2 days were randomly divided into atorvastatin (40 mg/day) (n = 40) and control (n = 50) groups. Delirium status of the patients was determined twice a day at 10:00 a.m. and 18:00 p.m. using the Richmond Agitation-Sedation Scale (RASS). RESULTS: Administration 40 mg/day of atorvastatin significantly reduced the mean RASS score and increased delirium-free days at both morning and afternoon time points compared to the control group (p < 0.05). CONCLUSIONS: Administration of atorvastatin had a significant positive effect on delirium status in patients admitted to the ICU.

The Relationship between Health Literacy Dimensions and Perceived Risk of Cardiovascular Disease in Middle-Aged Iranian Women.

BACKGROUND: The purpose of the study was to investigate the relationship between health literacy dimensions and the perceived risk of cardiovascular disease in middle-aged Iranian women. MATERIALS AND METHODS: This is a descriptive-correlational study in which 280 women aged 40-60 years were investigated by random cluster sampling out of seven health centers in Yazd city in 2018. Data collection tools included predesigned demographic information from a standard Health Literacy for Iranian Adults (HELIA), and a standard perceived susceptibility and perceived risk components of the preventive behaviors of cardiovascular disease questionnaire. The data were analyzed using one-way ANOVA, independent t-test, Kruskal-Wallis, and Mann Whitney tests. RESULTS: A significant relationship was identified between demographic information and health literacy (p < 0.001). The mean (SD) scores of the perceived risk of cardiovascular disease and health literacy appeared to be 30.71 (5.10) and 35.62 (15.32), respectively. The perceived risk of cardiovascular disease in the participants turned out to be significantly correlated with the accessibility dimension of health literacy (r = 0.31, p < 0.001), but it failed to have any significant relationship with demographic information, especially obesity. CONCLUSIONS: As there is a significant relationship between health literacy and perceived risk of cardiovascular disease, hence increasing the health literacy of middle-aged women, especially in persons with high body mass index through the media and health centers, considered as an important source of health information, can be an appropriate task to augment the perceived risk of cardiovascular diseases.

Nano-Fe3O4@walnut shell/Cu(ii) as a highly effective environmentally friendly catalyst for the one-pot pseudo three-component synthesis of 1,3-oxazine derivatives under solvent-free conditions.

Fe3O4@walnut shell/Cu(ii) as an eco-friendly bio-based magnetic nano-catalyst was prepared by adding CuCl2 to Fe3O4@walnut shell in alkaline medium. A series of 2-aryl/alkyl-2,3-dihydro-1H-naphtho[1,2-e][1,3]oxazines were synthesized by the one-pot pseudo three-component reaction of ß-naphthol, formaldehyde and various amines using nano-Fe3O4@walnut shell/Cu(ii) at 60 °C under solvent-free conditions. The catalyst was removed from the reaction mixture by an external magnet and was reusable several times without any considerable loss of its activity. This protocol has several advantages such as excellent yields, short reaction times, clean and convenient procedure, easy work-up and use of an eco-friendly catalyst.

Medication Errors in Patients with Enteral Feeding Tubes in the Intensive Care Unit.

OBJECTIVE: Most patients admitted to Intensive Care Units (ICU) have problems in using oral medication or ingesting solid forms of drugs. Selecting the most suitable dosage form in such patients is a challenge. The current study was conducted to assess the frequency and types of errors of oral medication administration in patients with enteral feeding tubes or suffering swallowing problems. METHODS: A cross-sectional study was performed in the ICU of Shahid Sadoughi Hospital, Yazd, Iran. Patients were assessed for the incidence and types of medication errors occurring in the process of preparation and administration of oral medicines. FINDINGS: Ninety-four patients were involved in this study and 10,250 administrations were observed. Totally, 4753 errors occurred among the studied patients. The most commonly used drugs were pantoprazole tablet, piracetam syrup, and losartan tablet. A total of 128 different types of drugs and nine different oral pharmaceutical preparations were prescribed for the patients. Forty-one (35.34%) out of 116 different solid drugs (except effervescent tablets and powders) could be substituted by liquid or injectable forms. The most common error was the wrong time of administration. Errors of wrong dose preparation and administration accounted for 24.04% and 25.31% of all errors, respectively. CONCLUSION: In this study, at least three-fourth of the patients experienced medication errors. The occurrence of these errors can greatly impair the quality of the patients' pharmacotherapy, and more attention should be paid to this issue.

Diagnostic value of sputum adenosine deaminase (ADA) level in pulmonary tuberculosis.

INTRODUCTION: Tuberculosis is still a considerable health problem in many countries. Rapid diagnosis of this disease is important, and adenosine deaminase (ADA) has been used as a diagnostic test. The aim of this study was to assess the diagnostic value of ADA in the sputum of patients with pulmonary tuberculosis. METHODS: The current study included 40 patients with pulmonary tuberculosis (culture positive, smear ±) and 42 patients with non tuberculosis pulmonary diseases (culture negative). ADA was measured on all of the samples. RESULTS: The median value of ADA in non-tuberculosis patients was 2.94 (4.2) U/L and 4.01 (6.54) U/L in tuberculosis patients, but this difference was not statistically significant (p=0.100). The cut-off point of 3.1 U/L had a sensitivity of 61% and a specificity of 53%, the cut-off point of 2.81 U/L had a sensitivity of 64% and a specificity of 50% and the cut-off point of 2.78 U/L had a sensitivity of 65% and a specificity of 48%. The positive predictive values for cut-off points of 3.1, 2.81 and 2.78 U/L were 55.7%, 57.44% and 69.23%, respectively. The negative predictive values for the abovementioned cut-off points were 56.75%, 57.14% and 55.88%, respectively. CONCLUSION: Our results showed that sputum ADA test is neither specific nor sensitive. Because of its low sensitivity and specificity, determination of sputum ADA for the diagnosis of pulmonary tuberculosis is not recommended.

The efficacy of hepatitis B vaccine in Iranian population: A systematic review and meta-analysis.

INTRODUCTION: Hepatitis B infection is an important health problem all over the world, and according to the studies, Iran is a country with intermediate prevalence, so vaccination is a cost-benefit approach. In this study, evidence about the efficacy of hepatitis B vaccine was collected by systematic review methods and its amount was estimated by a meta-analysis. MATERIALS AND METHODS: In this study, documents and literature search were performed using valid key words in Information Sciences Institute, PubMed, Scientific Information Data base, and Iranmedex databases from 1997 to 2010 in different regions of Iran. All cross-sectional studies about the efficacy of hepatitis B vaccine in Iran which fulfilled the inclusion criteria entered the study. Antibody titer (Anti-hemoglobins > 10 IU/L) was considered as the desired efficacy. In order to present the results, prevalence and Forest plot were used and for evaluation of the inconsistency meta-regression model and I(2) index were used. We used R.15.3.2 software for analysis. RESULTS: Totally 64 studies (52 studies in general population and 12 studies among specific populations) including 12,575 subjects with age range from 8 months to 55 years entered the meta-analysis. The efficacy was 86.3% (confidence interval [CI]: 83.9-88.7%) in the general population and 59.62% (CI: 47.9-71.29%) in specific patient populations. Also the efficacy was significantly related to the year of publication, age and gender (P < 0.05). CONCLUSION: Prevention is an important issue in general health. Hepatitis B vaccination is one of the methods used to prevent hepatitis B infection. According to this study, the efficacy of hepatitis B vaccination was more than 80% in general population, so injection of full course of hepatitis B vaccinationis enough and booster dose is not required.
