Epidemiology of substance and opium use among adult residents of Tehran; a comprehensive report from Tehran cohort study (TeCS).

BACKGROUND: The prevalence and burden of substance and opium use have increased worldwide over the past decades. In light of rapid population changes in Tehran, we aimed to evaluate the prevalence of opium and other substance use among adult residents in Tehran, Iran. METHOD: From March 2016 to March 2019, we utilized data from 8 296 participants in the Tehran Cohort Study recruitment phase (TeCS). We calculated the age-sex-weighted prevalence of substance use and the geographic distribution of substance use in Tehran. We also used logistic regression analysis to determine possible determinants of opium use. RESULT: We analyzed data from 8 259 eligible participants with complete substance use data and the average age of participants was 53.7 ± 12.75 years. The prevalence of substance use was 5.6% (95% confidence interval [CI]: 4.6- 7.1%). Substance use was more common in males than females (Prevalence: 10.5% [95% CI: 8.6- 12.6%] vs. 0.5% [95% CI: 0.2- 1.2%], respectively). The age-sex weighted prevalence of substance use was 5.4% (95% CI: 4.6-7.1%). Moreover, opium was the most frequently used substance by 95.8% of substance users. Additionally, we found that male gender (Odds ratio [OR]: 12.1, P < 0.001), alcohol intake (OR: 1.3, P = 0.016), and smoking (OR: 8.5, P < 0.001) were independently associated with opium use. CONCLUSIONS: We found that the prevalence of substance use in Tehran was 5.6%, and opium was the most frequently used substance. In addition, male gender, lower levels of education, alcohol, and tobacco consumption are the main risk factors for substance use in Tehran. Healthcare providers and policymakers can utilize our results to implement preventive strategies to minimize substance use in Tehran.

Epidemiology and prevalence of tobacco use in Tehran; a report from the recruitment phase of Tehran cohort study.

INTRODUCTION: Tobacco use is a major health concern worldwide, especially in low/middle-income countries. We aimed to assess the prevalence of cigarette smoking, waterpipe, and pipe use in Tehran, Iran. METHODS: We used data from 8272 participants of the Tehran Cohort Study recruitment phase. Tobacco use was defined as a positive answer to using cigarettes, waterpipes, or pipes. Participants who did not report tobacco use during the interview but had a previous smoking history were categorized as former users. Age- and sex-weighted prevalence rates were calculated based on the national census data, and characteristics of current and former tobacco users were analyzed. RESULTS: Age- and sex-weighted prevalence of current tobacco users, cigarette smokers, waterpipe, and pipe users in Tehran was 19.8%, 14.9%, 6.1%, and 0.5%, respectively. Current tobacco use was higher in younger individuals (35-45 years: 23.4% vs. ≥ 75 years: 10.4%, P < 0.001) and men compared to women (32.9% vs. 7.7% P < 0.001). The prevalence of tobacco use increased with more years of education (> 12 years: 19.3% vs. illiterate: 9.7%, P < 0.001), lower body mass index (< 20 kg/m2: 31.3% vs. ≥ 35 kg/m2: 13.8%, P < 0.001), higher physical activity (high: 23.0% vs. low: 16.4%, P < 0.001), opium (user: 66.6% vs. non-user: 16.5%, P < 0.001), and alcohol use (drinker: 57.5% vs. non-drinker: 15.4%, P < 0.001). Waterpipe users were younger (46.1 vs. 53.2 years) and had a narrower gender gap in prevalence than cigarette smokers (male/female ratio in waterpipe users: 2.39 vs. cigarette smokers: 5.47). Opium (OR = 5.557, P < 0.001) and alcohol consumption (OR = 4.737, P < 0.001) were strongly associated with tobacco use. Hypertension was negatively associated with tobacco use (OR = 0.774, P = 0.005). CONCLUSION: The concerning prevalence of tobacco use in Tehran and its large gender gap for cigarette and waterpipe use warrant tailored preventive policies.

The effect of group logotherapy on spirituality and preoperative anxiety in patients seeking open heart surgery referring to Tehran Heart Center in 2020.

BACKGROUND AND PURPOSE: Most patients experience anxiety before heart surgery. On the other hand, spiritual health can improve the candidate patient's adaptation to surgery. Therefore, this study aimed to investigate the effect of group logotherapy on spirituality and anxiety of patients undergoing cardiac surgery. MATERIALS AND METHODS: In this quasi-experimental study, 60 hospitalized candidates for cardiac surgery were randomly assigned to two groups (30 in the experimental group, 30 in the control group). To measure anxiety and relationship with God, Beck Anxiety Questionnaire and the researcher-made scale about relationship with God (reconstruction of Lawrence's scale of perception of God) were used, respectively. In the intervention group, in addition to drug therapy, individuals received two sessions of group discussion and spiritual skills training using the behavioral-cognitive method with emphasis on spiritual thoughts and problem-solving methods, but the control group received only drug therapy. Data were analyzed using SPSS software. RESULTS: In the experimental group, the anxiety scores mean in the posttest and follow-up were significantly lower than the pretest (P < 0.05), while the mean anxiety in the control group in the posttest stage was not significantly different, but at the follow-up stage, it was significantly lower than the pretest, but the decrease in mean anxiety in the experimental group was greater (P < 0.05). The mean subscales of relationship with god (influence, divine providence, acceptance, presence, challenge, benevolence) were significantly higher in the experimental and control groups in the follow-up stage than the pretest, but the increase in the mean of these variables was more in the experimental group in the follow-up stage (P < 0.05). CONCLUSION: Findings showed that the components of relationship with God are a good predictor of pre-surgery anxiety, so by focusing on spiritual training of patients who are candidates for surgery, the incidence or severity of anxiety can be reduced.

Efficacy of Date Palm Pollen in the Male Sexual Dysfunction after Coronary Artery Bypass Graft: A Randomized, Double-Blind, Clinical Trial.

Background: Bypass graft surgery of the coronary artery has a significant effect on the creation and development of sexual dysfunction among male patients. The previous studies have demonstrated that date palm pollen (DPP) increases the count and quality of sperm. Additionally, it has been shown that DPP has a protective effect against myocardial infarction and cardiac remodeling. Therefore, this is the first study investigating the impact of DPP (Phoenix dactylifera L.) on managing male sexual dysfunction after coronary artery bypass graft. Methods: This randomized, double-blind, placebo-controlled clinical trial was conducted on 60 patients (DPP group n = 30, control group n = 30) of Iranian men after coronary artery bypass graft. Two parallel groups were randomly generated from the study participants. The intervention group was prescribed 3 grams of the powder of DPP twice a day (9 AM and 9 PM) for two months, while the control group received the same prescription of the placebo powder. Results: The DPP consumption significantly increased the International Index of Erectile Function (IIEF) (from 23.21 to 46.57) and the Hurlbert Index of Sexual Desire (HISD) (from 59.39 to 64.45) scores over time in the intervention group. However, there were no significant changes in the control group. Conclusion: Daily intake of 6 g DPP for two months exhibited beneficial effects on the symptoms of male sexual dysfunction in patients who have undergone coronary artery bypass graft (CABG).

Alterations in auditory change detection associated with tinnitus residual inhibition induced by auditory electrical stimulation.

BACKGROUND: Residual inhibition (RI) is a temporary phenomenon that happens following offset of appropriate complete or partial acoustical and electrical masking stimulations in people who experience tinnitus. The biologic mechanisms associated with RI are not yet fully understood. Few studies have been focused on RI. Auditory mismatch negativity (MMN) as a change-detection tool may be an appropriate tool to explore the processing changes because of tinnitus and RI. PURPOSE: The purpose of this study was to investigate alterations in auditory change detection and auditory sensory memory related to RI induced by auditory electrical stimulation (AES) using MMN brain mapping in participants with tinnitus. RESEARCH DESIGN: This investigation was a single-blind randomized controlled clinical trial study. Participants were randomly assigned into two groups: AES and placebo electrical stimulation (PES). STUDY SAMPLE: Twenty-eight participants with chronic subjective tinnitus aged 22- to 45-yr-old participated in the study. INTERVENTION: After randomization, all participants received both AES and PES for 1 min in different sessions. DATA COLLECTION AND ANALYSIS: Brain mapping of multifeature MMN paradigm was recorded from 29 scalp electrodes pre- and post-AES and PES. Following AES, participants were categorized into two groups: RI and nonresidual inhibition (NRI). The grand average MMN waveforms and isopotential topographic maps were obtained in RI, NRI, and PES groups. RESULTS: Three MMN parameters for five deviants of frequency, intensity, duration, location, and silent gap were compared among three groups of RI, NRI, and PES. Statistical analyses revealed significant between-subject effects for AES on MMN amplitude of frequency and duration deviant, MMN area under the curve of frequency, intensity, and duration deviants. CONCLUSIONS: Presence of RI can reestablish change-detection mechanisms in the central auditory pathways. It is suggested that MMN is reliable for assessment of change-detection system in people with tinnitus. It can be a useful technique in monitoring effects of treatments and rehabilitation.

Alterations in early auditory evoked potentials and brainstem transmission time associated with tinnitus residual inhibition induced by auditory electrical stimulation.

INTRODUCTION: Residual inhibition (RI) is the temporary inhibition of tinnitus by use of masking stimuli when the device is turned off. OBJECTIVE: The main aim of this study was to evaluate the effects of RI induced by auditory electrical stimulation (AES) in the primary auditory pathways using early auditory-evoked potentials (AEPs) in subjective idiopathic tinnitus (SIT) subjects. MATERIALS AND METHODS: A randomized placebo-controlled study was conducted on forty-four tinnitus subjects. All enrolled subjects based on the responses to AES, were divided into two groups of RI and Non-RI (NRI). The results of the electrocochleography (ECochG), auditory brain stem response (ABR) and brain stem transmission time (BTT) were determined and compared pre- and post-AES in the studied groups. RESULTS: The mean differences in the compound action potential (CAP) amplitudes and III/V and I/V amplitude ratios were significantly different between the RI, NRI and PES controls. BTT was significantly decreased associated with RI. CONCLUSION: The observed changes in AEP associated with RI suggested some peripheral and central auditory alterations. Synchronized discharges of the auditory nerve fibers and inhibition of the abnormal activity of the cochlear nerve by AES may play important roles associated with RI. Further comprehensive studies are required to determine the mechanisms of RI more precisely.

The effect of adding homeopathic treatment to rehabilitation on muscle tone of children with spastic cerebral palsy.

OBJECTIVE: To determine the effect of adding homeopathic treatment to routine rehabilitation techniques on muscle tone of children with spastic cerebral palsy (CP). METHODS: This study was a double-blind clinical trial. Twenty-four subjects were recruited from a developmental disorders clinic in Tehran in 2004. Subjects were divided into case and control groups. The routine rehabilitation techniques were carried out for 4 months on both the groups. The control group received placebo and the case group received homeopathy drugs. Both groups were evaluated and compared for muscle tone before and 4 months after treatment using the Modified Ashworth Scale. RESULTS: Showed no positive changes in the patients with homeopathy and occupational therapy at the end of treatment, and there were no statistically significant differences in tonicity of upper and lower limbs, trunk and neck in the case group in comparison with the control group. CONCLUSION: Adding homeopathy to rehabilitation had no significant effect on spasm of CP children as measured by Ashworth test.
