Transfusion-related acute lung injury in multiple traumatized patients

Background: Many of the multiple traumatized patients who refer to the hospital need transfusion. Transfusion-related acute lung injury (TRALI) is a serious clinical syndrome associated with the transfusion of plasma-containing blood components. In the article, we present a case of TRALI following transfusion of packed red blood cells Case Presentation: A 24 year old male referred to Shahid Beheshti Hospital due to multiple trauma with left femoral and humerus fractures. Due to severe anemia he received 3 units of packed red blood cells. The symptoms of TRALI began 2 hours after transfusion. He was transferred to intensive care unit (ICU) due to metabolic acidosis and severe hypoxia. The TRALI was confirmed after ruling out the other probable pulmonary diseases. He recovered and was discharged. Conclusion: Transfusion related acute lung injury should be considered in any case receiving transfusion of plasma containing blood components

Scopolamine reduces the density of M1 muscarinic neurons in rats' hippocampus

Cholinergic system in CNS is involved in learning and memory. Scopolamine as muscarinic acetylcholine receptor antagonist is used for creation of memory impairment. The purpose of this study is evaluation of scopolamine-based amnesia on memory retention and the effect of this phenomenon on the number of neurons contains M1-receptors in the male Wistar rats hippocampal regions. Thirty-five male Wistar rats (200±20 g) were distributed randomly into five groups. Control group (intact samples) and 3 experimental groups with sham group (saline) were tested by the method of passive avoidance (shuttle box) in doses of 0.2, 0.5 and 1 mg/kg (intraperitoneally) as a single dose. After one week, memory test was taken from the rats. Finally, brains dissected from sacrificed rats, and then processed tissues were stained with antibody against M1 receptors (Immunohistochemistry technique) followed by counting of hippocampal CA1, CA3 and DG regions. Our results showed significant decrease in neurons contains M1-receptors in all area of hippocampus. We found that the less number of M1-neurons showed in 1 mg/kg dose of scopolamine. We concluded that scopolamine as muscarinic acetylcholine receptor antagonist can reduce dose-dependently the density of M1-neurons in all areas of hippocampus

Informational and structural needs of nursing data classification in computerized systems

Background & Aim: Healthcare classification systems help to gather information and process health data. Nursing management focus on developing computerized records to answer legal, managerial and clinical needs. The Classification systems help organizations to use nursing data. This study investigated informational and structural needs of nursing data classification. Methods & Materials: This descriptive-comparative study was carried out in 2009. Current classification systems for nursing were investigated and their specifications were gathered in a questionnaire. The items were prioritized by experts in four degrees. Using statistical analysis items with a priority over 80 percent (average 2.4) were selected. Results: Findings about nursing diagnosis, intervention and outcomes showed that diagnosis item (average 2.93 out of 3), intervention item (average 2.52 out of 3), and outcome item (average 2.84 out of 3) should be presented in the system. Structure of nursing data classification was identified as a hierarchical and combinational classification. The computerized terminology (average 1.86 out of 3) had no priority. Conclusion: It is suggested to make decisions for standardizing nursing data to use in computerized systems. Since, nursing system in Iran is moving toward defining tariff for nursing services, coding nursing care components will help this plan to be developed

Role of histaminegic and calcium channels in the inhibitory effects of hydroalcoholic extract of matricaria recutita L. on isolated rabbit jejunum

Introduction: Considering the long traditional history of anti-inflammatory and anti-spasmodic effects of Matricria spices on the gastrointestinal system, the present study aimed to investigate the role of calcium channels and Histamine receptors in the inhibitory effects of hydroalcoholic dry extract of German chamomile (Matricaria recutita L.) on the isolated rabbit jejunum. Methods: All experiments were done on the isolated jejunum of New Zealand rabbits (1.8-2.5 kg). Dry extract of aerial parts of M. recutita was obtained by the maceration technique. The study was performed on two groups (n=6 in each group). In the first group, the effects of cumulative concentrations of M. recutita (3×10-3-1×10-2 mg/ml) on normal and K+-induced contractions (50 mM) of isolated jejunum were studied. In the second group, the inhibitory role of M. recutita (3 – 13×10-3 mg/ml) was evaluated in the presence and absence of histamine and cetrizine. In the presence and absence of 10 μM certizine, a histamine H1-antagonist, a concentration-dependent inhibitory effect of M. recutita extract in the range of 3-13×10-3 mg/ml was recorded the rabbit jejunum. Results: Results showed that EC50 of M. recutita in the absence and presence of K+ was 6.3×10-3 and 6.5×10- 3mg/ml, respectively. IC50 values for two concentrations of M. recutita (8×10-3 , 1×10-2 ) to abrogated contractive phase of Histamine was 9.55 × 10-6 and 1.57 × 10-6 μM. Cetrizine (10 μM) abolished inhibitory effects of M. recutita (IC50=3.6×10-3), (p< 0.001). Conclusion: Dry extract of matricaria recutita had inhibitory effects on the contractions of isolated rabbit jejunum. Calcium channels and histamine were involved in these antispasmodic effects

On the Globalization of the {QAnon} Conspiracy Theory Through {Telegram}

QAnon is a far-right conspiracy theory that became popular and mainstreamover the past few years. Worryingly, the QAnon conspiracy theory hasimplications in the real world, with supporters of the theory participating inreal-world violent acts like the US capitol attack in 2021. At the same time,the QAnon theory started evolving into a global phenomenon by attractingfollowers across the globe and, in particular, in Europe. Therefore, it isimperative to understand how the QAnon theory became a worldwide phenomenon andhow this dissemination has been happening in the online space. This paperperforms a large-scale data analysis of QAnon through Telegram by collecting4.5M messages posted in 161 QAnon groups/channels. Using Google's PerspectiveAPI, we analyze the toxicity of QAnon content across languages and over time.Also, using a BERT-based topic modeling approach, we analyze the QAnondiscourse across multiple languages. Among other things, we find that theGerman language is prevalent in QAnon groups/channels on Telegram, evenovershadowing English after 2020. Also, we find that content posted in Germanand Portuguese tends to be more toxic compared to English. Our topic modelingindicates that QAnon supporters discuss various topics of interest withinfar-right movements, including world politics, conspiracy theories, COVID-19,and the anti-vaccination movement. Taken all together, we perform the firstmultilingual study on QAnon through Telegram and paint a nuanced overview ofthe globalization of the QAnon theory.<br

Relapse coping strategies in young adults addicts: A quantitative study in Iran

Background: Cognitive-behavioral coping approach is known as an effective strategy to preventing relapse. Its goal is to forget incompatible behaviors and replaces them with the compatible answers. Objectives: This study examines relapse coping strategies in young adults in selected substance abuse treatment centers in Iran. Patients and Methods: The present is a descriptive cross-sectional study. The sample consisted of 70 self-referred young addicts (18-24 years). Adolescence Relapse Coping Questionnaire was used to assess relapse coping strategies. Descriptive statistics was used to analyze the data. Results: The findings revealed that 71.2 have experienced a relapse totally. It was hard to control the hypothetical high risk situation and they greatly wanted to use the substance (mean 7.39 of 10). Addicts have used of all three coping skills in »definitely would do» level. Conclusion: Enhancing self-efficacy through training coping skills, especially abstinence - focused coping skills to react properly in high risk situation can be useful. © 2016 Indian Psychiatric Society | Published by Wolters Kluwer - Medknow

Effects of curcumin on body weight, glycemic control and serum lipids in women with polycystic ovary syndrome: A randomized, double-blind, placebo-controlled trial

Objective: The aim of this study was to evaluate the effect of curcumin on body weight, glycemic control and serum lipids in women suffering from polycystic ovary syndrome (PCOS). Methods: The current randomized, double-blinded, placebo-controlled clinical trial was performed on 60 subjects with PCOS, aged 18�40 years old. Subjects were randomly allocated to take 500 mg/day curcumin (n = 30) or placebo (n = 30) for 12 weeks. Glycemic control and serum lipids were measured at baseline and after the 12-week intervention. Using RT-PCR method, gene expression related to insulin and lipid metabolism was evaluated. Results: Curcumin significantly decreased weight (�0.8 ± 0.9 vs. �0.2 ± 0.8 kg, P = 0.03) and BMI (�0.3 ± 0.4 vs. �0.1 ± 0.3 kg/m2, P = 0.03). Curcumin, compared with the placebo, significantly reduced fasting glucose (β �2.63 mg/dL; 95 CI, �4.21, �1.05; P = 0.002), serum insulin (β �1.16 μIU/mL; 95 CI, �2.12, �0.19; P = 0.02), insulin resistance (β �0.26; 95 CI, �0.48, �0.03; P = 0.02), and significantly increased insulin sensitivity (β 0.006; 95 CI, 0.001, 0.01; P = 0.02). In addition, taking curcumin was associated with a significant reduction in total cholesterol (β �15.86 mg/dL; 95 CI, �24.48, �7.24; P = 0.001), LDL-cholesterol (β �16.09 mg/dL; 95 CI, �25.11, �7.06; P = 0.001) and total-/HDL-cholesterol ratio (β �0.62; 95 CI, �0.93, �0.30; P &lt; 0.001), and a significant increase in HDL-cholesterol levels (β 2.14 mg/dL; 95 CI, 0.36, 3.92; P = 0.01) compared with the placebo. Additionally, curcumin administration up-regulated gene expression of peroxisome proliferator-activated receptor gamma (PPAR-γ) (P = 0.03) and low-density lipoprotein receptor (LDLR) (P &lt; 0.001) compared with the placebo. Conclusions: Overall, curcumin administration for 12 weeks to women with PCOS had beneficial effects on body weight, glycemic control, serum lipids except triglycerides and VLDL-cholesterol levels, and gene expression of PPAR-γ and LDLR.

Association between socio-demographic factors and diabetes mellitus in the north of Iran: A population-based study

Objective: This study considers the prevalence of DM and some related factors among adults in the Golestan province (north of Iran) in 2006. Methods: This is a Cross-sectional-Descriptive and population-based study, carried out among 1999 cases (1000 men and 999 women) between 25 and 65 years old. Participants were chosen by cluster and stratified sampling in urban and rural areas. Data on socio-demographic factors were collected using questionnaire, and anthropometric and biochemical indexes were measured. Fasting Blood Sugar (FBS) equal to or over 126 mg/dl was classified as type 2 DM. Results: Mean of age was 39.2 years and mean ± SD of FBS among men and women was 94.51 ± 32.91 and 98.2 ± 40.1 mg/dl, respectively. Prevalence of DM was 8.3% [(men = 6.8% and women = 9.7%), (urban = 10.5% and villages = 6.4%)]. Twenty-five percent of patients were undiagnosed as whole, 43% of patients were unaware of their problem, in men more than in women (48.5% versus 39.2%) and in rural area more than in urban area (35.1% versus 54.4%). We showed a positive and significant correlation between FBS and age, waist circumference and BMI (P = 0.01). Conclusion: DM was the one of the biggest health problems in the north of Iran, and half of them were unaware of their morbidity. DM was influenced by socio-demographic factors. © 2010 International Journal of Diabetes Mellitus. Published by Elsevier Ltd. All rights reserved
