Efficacy of a Persian herbal medicine compound on coronavirus disease 2019 (COVID-19): A randomized clinical trial.

Background: The global attention to the capacities of traditional medicine for alleviating the clinical manifestations of COVID-19 has been growing. The present trial aimed to evaluate the efficacy and safety of a Persian herbal medicine formula among patients with COVID-19. Methods: The present trial was conducted in Afzalipour hospital, Kerman, Iran, from June to September 2020. Hospitalized COVID-19 patients were randomly divided into intervention (Persian herbal medicine formula + routine treatment) or control (only routine treatment) groups. The intervention group received both capsule number 1 and 2 every 8 hours for 7 days. Capsule number 1 contained extract of the Glycyrrhiza glabra, Punica granatum, and Rheum palmatum, and the second capsule was filled by Nigella sativa powder. Participants were followed up to 7 days. The primary outcome was the number of hospitalization days, while cough, fever, and respiratory rate, days on oxygen (O2) therapy, and mortality rate were considered as the secondary outcomes. Results: Eighty-two patients were enrolled to the study, while 79 cases completed the trial and their data were analyzed (mean age: 59.1 ± 17.1 years). Based on the results, the Persian medicine formula decreased the mean hospitalization days, so that the mean difference of length of hospitalization as primary outcome was 2.95 ± 0.43 days. A significant clinical improvement was observed regarding dyspnea, need for O2) therapy, and respiratory rate in the intervention group. No adverse effects were reported. Conclusion: The present study supported the use of the Persian medicine formula as an adjuvant therapy for hospitalized COVID-19 patients.

The Efficacy of Kohl (Surma) and Erythromycin in Treatment of Blepharitis: An Open-Label Clinical Trial.

INTRODUCTION: Blepharitis is a common and chronic form of eyelid inflammation. Blepharitis treatment aims to decrease symptoms through antibacterial effects. One of the most common treatments of eyelid diseases in traditional medicine is using kohl. This clinical trial aimed to investigate its efficacy as a complementary treatment in staphylococcal blepharitis through an open-label clinical trial. MATERIALS AND METHODS: Thirty patients were randomized to receive kohl in one eye contralateral and erythromycin ointment in another eye for 90 days. At baseline and after 90 days of treatment, symptoms, clinical signs, and side effects of treatments were recorded. Statistical analysis was carried out using SPSS software, version 19. RESULTS: Despite randomization, there was a significant difference between the intervention and control eyes in the baseline mean clinical score (intervention eye: 9.86 (2.95) and control eye: 4.30 (2.81), P < 0.001). The degree of reduction of related signs and symptoms in the eyes treated with kohl was significantly higher than that in the control group: (5.2 vs. 2.20, P < 0.001) for symptoms and (7.40 vs. 2.46, P < 0.001) for clinical signs. Cohen's d statistic for mean difference of sign and symptom was 2.4 and 1.75, respectively, indicating a very strong effect. CONCLUSION: The present study results demonstrated a significant improvement in blepharitis-related signs and symptoms. The degree of improvement in the eyes treated with kohl was much higher than that in the control eyes.

Clinical evaluation of the effect of Zataria multiflora Boiss and Trachyspermum copticum (L.) on the patients with irritable bowel syndrome.

BACKGROUND AND AIM: Irritable Bowel Syndrome (IBS) is the most common gastrointestinal dysfunction characterized by abdominal pain or discomfort, as well as changes in bowel movements and stool shape. Given the global trend towards the increased use of complementary and alternative medicine (CAM), the high prevalence of IBS, the lack of a standard treatment for all IBS subtypes, and patients' willingness to use CAM treatments, investigations into CAM treatments are needed. Accordingly, the present study aimed to investigate the effect of a mix of two herbal medicines (Zataria-Trachyspermum, ZT) on the clinical symptoms of patients with IBS. EXPERIMENTAL PROCEDURE: The present study was performed on 3 groups including the positive control, experimental, and placebo groups. The sample size was calculated as 150 participants. Fifty patients were assigned to one of three parallel groups (ZT capsule, placebo, and mebeverine capsule) by block randomization. All three groups were treated for 4 weeks. The patients were monitored in the follow-up stage for 2 additional weeks. RESULTS: After the fourth week of intervention, symptoms of pain, bloating, and reflux showed a significant decrease in the ZT group compared to the placebo and mebeverine groups (P <0.05). Moreover, the participants in the ZT group reported a significant decrease in fatigue compared to the other two groups (P <0.05). CONCLUSION: This study confirmed the positive effect of ZT on IBS symptoms, especially pain, bloating, constipation, and bowel movements.

Opium and Cigarette Smoking are Independently Associated with Bladder Cancer: The Findings of a Matched Case - Control Study.

BACKGROUND: Bladder cancer disproportionally affects the communities. While it is the ninth most common cancer in the world, in some parts of Iran including Kerman province it is the most common cancer among men. This study aimed to determine potential risk factors of bladder cancer in Kerman province, Iran. METHODS: During February to July 2020, in this matched hospital-based case-control study, 100 patients with bladder cancer and 200 healthy individuals (matched in age and sex) were recruited. Socio-demographics status, occupational exposures, common diet, history of drug use and family history of cancer, were collected using a structured questionnaire. Bivariable and multivariable logistic regression were applied and crude and adjusted odds ratios (AOR) along with their 95% confidence intervals (95%CI) were calculated. Data were analyzed using Stata version 14 software. RESULTS: Opium consumption, cigarette smoking and low level of income were associated with increased chance of bladder cancer. Compared to never use, use of opium up to 18000 Gram -year was associated with increased chance of bladder cancer (AOR: 6; 95% CI =2.3, 15.5). The chance was higher among those who used opium more than 18,000 Gram - year (AOR: 11.3; 95% CI =2.3, 15.5). In comparison with never smokers, the chance of bladder cancer increased among those who smoked up to 20 pack-year cigarette) (AOR: 3.4; 95%CI= 1.3, 8.9) and those who smoke ≥ 20 pack-year (AOR: 15.8; 95% CI= 5.9, 42.4). CONCLUSIONS: The observed strong dose-response association between opium consumption, cigarette smoking and bladder cancer highlights the need for extension of harm reduction programs especially in regions with high burden of disease.

A Shift Toward Childbearing in One-Child Families Through a Mindfulness-Based Stress Reduction Program: A Randomized Controlled Trial.

Objective: Fertility patterns are a key to the estimation of future population size, but they are restricted by serious indecision. One-child families are one of these patterns that is caused by a set of factors and one of these factors is the fear of re-pregnancy. In this regard, this study aimed to use a mindfulness-based stress reduction (MBSR) program to reduce the fear of women who have been experiencing anxiety after their first pregnancy and delivery. Materials and methods: This interventional study was conducted on 67 one-child women, who at least 6 years have been passed since the birth of their child and according to the short form of the Pregnancy Related Anxiety Questionnaire (PRAQ-17), have been experienced anxiety. These women were randomly divided into control and intervention groups. For the intervention group, the MBSR program was conducted in 8 sessions, once every week, each session lasting 2.5 hours. At the end of the program, a second PRAQ-17 was completed by both groups. Results: The findings showed that the MBSR approach in the intervention group significantly decreased the anxiety score in total (p=0.001) and individually in all subcategories. Conclusion: The MBSR approach can reduce the anxiety of one-child women who have experienced anxiety after their pregnancy and childbirth. Thus, using this method in helping women with pregnancy-related anxiety is recommended to increase the birth rate.

Barriers and motivators to participation and retention in HIV/HCV cohort studies among people who inject drugs: a community consultation in Iran.

BACKGROUND: The lack of robust estimates of HIV/HCV incidence among people who inject drugs (PWID) in Iran calls for well-designed prospective cohort studies. Successful recruitment and follow-up of PWID in cohort studies may require formative assessment of barriers PWID are faced with in participation and retention in cohort studies and factors they think may facilitate their engagement in such studies. Using a focus group discussion (FGD) format, we conducted a consultation with PWID in southeast Iran to recognize those barriers and motivators. METHODS: Using targeted sampling and through snowball referrals, we recruited PWID (aged≥18, injected in last 6 months) from community-based drop-in centers (DICs), homeless shelters, and through outreach efforts to participate in four FGDs (one women-only). Socio-demographic characteristics, injection behaviors and self-reported HCV/HIV testing and diagnosis history were obtained. Then, a semi-structured FGD guide was applied to explore barriers and motivators to participation and retention in cohort studies among study participants. All FGD sessions were recorded and transcribed verbatim, removing any identifying information. The content of FGDs were analyzed by thematic analysis using an inductive approach. RESULTS: In total, 30 individuals (10 women) participated in the study. The median age of participants was 35 (IQR 31-40), with majority (73.3%) reporting injecting drug use within the last month. Only 40.0% reported ever being tested for HCV whereas a larger proportion (63.4%) reported ever being tested for HIV. While the majority were willing to participate in cohort studies, breach of confidentiality, fear of positive test results, perceived required commitment, and marginalization were reported as barriers to participation and retention in such studies. Monetary incentive, the thought of a better life, protection from police interventions and trust between health workers and PWID were addressed as motivators of engagement in cohort studies among PWID. CONCLUSIONS: Strategies to enhance data security and reduce stigma associated with injecting drug use along with involving peer workers in research, providing pre and post-test counselling and education and addressing the needs of more marginalized groups potentially through integrated healthcare programs and housing support are among few approaches that may help address barriers and strengthen the motivators for successful cohort studies among this population.

Population Size Estimation of Tramadol Misusers in Urban Population in Iran: Synthesis of Methods and Results.

BACKGROUND: Estimating the population who use drugs is essential for planning, monitoring, and evaluation of substance use prevention and treatment. This study aims to estimate the population who misuse tramadol in urban population in Iran. METHODS: We used the wisdom of the experts (WOTE) and network scale-up (NSU) methods to calculate the population of tramadol misusers in 10 provincial capitals of Iran, in 2016. The WOTE was conducted among pharmacists in drugstores and the personnel of traditional medicinal herbs stores. They guessed the best estimation of tramadol misusers population in their cities. The NSU method was conducted among the general population and participants were questioned about ever and daily, non-medical use of tramadol during last 12 months in their network. The median of the methods was used to calculate the proportion of the adult population (15-49 years old). FINDINGS: The population size of tramadol misusers in studied cities was 83300 [95% uncertainty limits (UL): 47960-256220]. This corresponded to 6.6 per 1000 (95% UL: 3.88-20.30) of the 15-49-year-old population. The projected number of tramadol misusers for all 31 provincial capitals was 118290 (95% UL: 68100-363130840) and 212440 (95% UL: 122310-653410) for all urban areas. NSU also estimated the number of people who misuse tramadol on daily basis. These numbers were 52000 (95% UL: 19940-176570) for studied cities, 73840 (95% UL: 28320-250740) for all 31 provincial capital cities, and 132610 (95% UL: 50860-450310) for all urban areas in Iran. CONCLUSION: This study presents information on high prevalence of tramadol misuse in urban population. We need national control measures and demand reduction programs to control tramadol misuse.
