Relationship between using cell phone and the risk of accident with motor vehicles: An analytical cross-sectional study

Purpose: Traffic accidents are one of the major health problems in the world, being the first cause of burden of illness and the second leading cause of death in Iran. The Sistan-Baluchestan province is one of the most accidental provinces of Iran with the highest rate of accidents-caused deaths. This study was conducted to determine the risk factors associated with traffic accidents in Zahedan through 2013 to 2016. Methods: This analytical cross-sectional study was carried out on 223 drivers from Zahedan who were traumatized by traffic accident and sent to Zahedan hospitals. The data were obtained through interviews taken by the trained interviewers via refereeing to the medical records and collected in the researcher-made checklist. Census was obtained from the study subjects. For data analysis, independent t-test, one-way ANOVA, Chi-square and logistic regression were used with the Stata software version 11.0. Results: In this study, 223 male subjects with the mean age of (32.54 ± 12.95) years, 39.8% single and 60.2% married, entered for investigation. Most accidents (38.8%) occurred between 12:00 to 17:59. While driving, 47.1% of the study subjects were using cell phones, 89.1% had manual use of mobile phones, 21.9% had a habit of sending short message service (SMS) and 23.4% had sent SMS within 10 min before the accident. The one way analysis of variance showed that the mean age of individuals with marital status, driving experience, education and accident with motorcycle were significantly different (p < 0.05). Also, the multivariate logistic regression test indicated a significant relationship of smoking, ethnicity, insurance and SMS typing while driving with motorcycle accident (p < 0.05). Conclusion: In this study, SMS and smoking while driving had the highest risk among the variables studied in the motorcycle accidents. Therefore, effective education attempting to enhance people''s awareness about the consequences of using cell phone and smoking during driving to reduce traffic accidents seems necessary.

Meta-analysis of epigenome-wide association studies of carotid intima-media thickness

Common carotid intima-media thickness (cIMT) is an index of subclinical atherosclerosis that is associated with ischemic stroke and coronary artery disease (CAD). We undertook a cross-sectional epigenome-wide association study (EWAS) of measures of cIMT in 6400 individuals. Mendelian randomization analysis was applied to investigate the potential causal role of DNA methylation in the link between atherosclerotic cardiovascular risk factors and cIMT or clinical cardiovascular disease. The CpG site cg05575921 was associated with cIMT (beta?=??0.0264, p value?=?3.5?×?10^–8) in the discovery panel and was replicated in replication panel (beta?=??0.07, p value?=?0.005). This CpG is located at chr5:81649347 in the intron 3 of the aryl hydrocarbon receptor repressor gene (AHRR). Our results indicate that DNA methylation at cg05575921 might be in the pathway between smoking, cIMT and stroke. Moreover, in a region-based analysis, 34 differentially methylated regions (DMRs) were identified of which a DMR upstream of ALOX12 showed the strongest association with cIMT (p value?=?1.4?×?10^–13). In conclusion, our study suggests that DNA methylation may play a role in the link between cardiovascular risk factors, cIMT and clinical cardiovascular disease.

     

Colonoscopy in the elderly

An evaluation of the utility, morbidity, and patient tolerance of colonoscopy in elderly (70 years) patients was undertaken and compared to data for a similar group of younger patients (50–70 years) who underwent colonoscopy during the same 48 months. Data reviewed for both groups included demographics, indications for colonoscopy, effectiveness of bowel preparation, colonoscopy completion, endoscopic findings, and complications. The mean age of the entire 656-patient population was 69±10 years; 87 (25%) of the 354 elderly patients were greater than 80 years of age and the average age of the 302-member control group was 59.8±5.8 years. Indications for colonoscopy were the same in both groups and included rectal bleeding, 134 (20%); prior colorectal operation, 115 (18%); a history of adenomatous polyps, 82 (12%); guaiac-positive stools, 49 (8%); abnormal finding on barium enema, 19 (3%); and miscellaneous other gastrointestinal symptoms, 151 (23%). Screening colonoscopy was performed in 106 (16%). Colonoscopy was successfully completed to the cecum or the ileocolic anastomosis in 85% (555/656) of the entire population. Only 78% (275/354) of elderly patients had colonoscopy successfully completed compared to 93% (281/302) of their younger counterparts (P=0.001). Elderly patients were significantly more likely to have an abnormality than younger patients (74% vs 60%, P<0.05). Malignant colorectal neoplasia was more common in the elderly (6% vs 2%, P=0.03); however, benign neoplasia was equally present in both age groups (30% vs 27%, P=NS). Thirty percent (195/656) of all patients underwent either snare polypectomy or biopsy. There were no perforations, and postprocedural hemorrhage occurred in 2% (4/195) and was unrelated to age. Overall morbidity, including procedural-related oxygen desaturation, was no different between the two groups. There were no deaths. We conclude that colonoscopy is safe in elderly patients and that advanced age does not, by itself, confer increased risk to the procedure. The lower completion rate in elderly patients mandated additional subsequent testing to complete colonic evaluation but was offset by the significantly increased likelihood of discovering treatable pathology. These results support the continued, aggressive use of colonoscopy in the colonic evaluation of the elderly.     

Immunological and In-Vivo Neurological Studies on a Benzoic Acid-Specific T-Cell-Derived Antigen-Binding Molecule from the Serum of a Toluene-Sensitive Patient

T-cell-derived antigen-binding molecules (TABMs) specific for benzoic acid were isolated from the serum of a toluene-sensitive patient. The resulting purified TABMs (BA-TABMs) did not contain immunoglobulin G and were associated with the cytokine transforming growth factor-β (TGF-β). BA-TABMs bound to benzoic acid conjugated to human serum albumin (BA-HSA), as well as to other chemicals conjugated to human serum albumin—including dinitrophenol and oxazolone. The binding of BA-TABMs to the conjugated chemicals increased the level of detectable TGF-β, and a similar effect was observed with the unconjugated chemicals, benzoic acid and 2,4-dinitrophenol glycine. The increase in TGF-β was critically dependent on the ratio between BA-TABMs and the conjugated or unconjugated chemicals; the increase was optimum at intermediate concentrations and absent at low and high concentrations. The authors used an established animal model in vivo and demonstrated that TGF-β enhanced the inflammatory response induced by the release of neuropeptides from sensory nerves; this enhancement occurred in a dose-dependent manner. The BA-TABMs also enhanced this neurogenic inflammatory response in a dose-dependent manner, and this effect was blocked by anti-TGF-β antibody. When the authors added either BA-HSA or benzoic acid, the effect of BA-TABMs on neurogenic inflammation was further enhanced at intermediate concentrations of antigen and was unaltered or reduced at higher concentrations. TABMs specific to particular chemicals, as a result of their association with cytokines (e.g., TGF-β), may be implicated in symptom production in chemically sensitive patients.     

Preclinical coronary endothelial dysfunction in Egyptian Behçet’s disease patients; Tc-99m sestamibi pharmacological Gated-SPECT,is it a useful screening tool?

IntroductionBehçet’s disease (BD) is an idiopathic multisystem disorder. Cardiac involvement[cardio-BD] occurs in 7–60% of BD patients. Technetium 99m-Methoxyisobutyl isonitrile (Tc-99m sestamibi) is a myocardial perfusion imaging agent that is used for evaluation of the coronary flow.Aim of the workTo evaluate the usefulness of Dipyridamole pharmacological stress test in conjunction with Tc-99m sestamibi cardiac gated single photon emission computed tomography (GSPECT) to investigate the prevalence of subclinical coronary endothelial dysfunction[SCED] in asymptomatic Egyptian BD patients; also to assess possibly associated clinical predictive variables.Patients and MethodsTwenty-five BD patients without overt cardiac involvement and fifteen healthy controls matched for age, BMI and sex were included. Database included full history, clinical examination, relevant laboratory tests, and Tc-99m sestamibi myocardial GSPECT with coronary angiography[CAG] in GSPECT positive cases. Disease activity was assessed using Behçet’s Disease Current Activity Form (BDCAF).ResultsSCED detected by reduced flow or left ventricular dysfunction (LVD) or both was found in 13/25[52%] of BD-patients[12 males and 1 female] vs. 1/15[6.7%] of controls[P < 0.0001] with normal CAG. Subjects with positive GSPECT had significantly older age[P = 0.01] and longer disease duration (P = 0.02) and were more frequently males (P < 0.0001) than those with negative GSPECT. No statistically significant differences between cases with negative and positive GSPECT were found regarding other clinical or laboratory parameters.ConclusionTc-99m sestamibi GSPECT could be a useful screening tool for detection of SCED in BD patients, so early prophylactic measures and therapy modifications could be considered.     

Topical Corticosteroids and Hospital Length of Stay in Children with Eczema Herpeticum

Abstract: There is concern that the use of topical corticosteroids in patients with eczema herpeticum may facilitate dissemination of herpes simplex virus and worsen disease. Our primary aim therefore was to determine whether topical corticosteroid use in children hospitalized with eczema herpeticum is associated with longer hospital length of stay (LOS). We performed a multicenter retrospective cohort study of 1,331 children ages 2 months to 17 years admitted with a diagnosis of eczema herpeticum between January 1, 2001, and March 31, 2010, to 42 tertiary care children’s hospitals in the Pediatric Health Information System database. Multivariable linear regression models determined the association between receipt of topical corticosteroid therapy on the first day of hospitalization and the main outcome measure: LOS. Receipt of topical corticosteroid therapy on day 1 of hospitalization was not associated with a longer LOS on unadjusted or multivariable analysis (p = 0.75). Receipt of topical calcineurin inhibitors during the hospitalization was also not associated with a longer LOS (p = 0.12). Receipt of systemic corticosteroids was associated with an 18% adjusted longer LOS (95% confidence interval 2%–36%; p = 0.03). Further study is needed to identify which children with eczema herpeticum may benefit from topical corticosteroids, but their use during active infection is not associated with poorer outcomes, although the use of systemic corticosteroids was associated with a longer LOS and should be avoided in patients with eczema herpeticum pending future prospective study.
