Excess Deaths During the COVID-19 Pandemic in Southern Iran: Estimating the Absolute Count and Relative Risk Using Ecological Data.

OBJECTIVES: The coronavirus disease 2019 (COVID-19) pandemic led to increased mortality rates. To assess this impact, this ecological study aimed to estimate the excess death counts in southern Iran. METHODS: The study obtained weekly death counts by linking the National Death Registry and Medical Care Monitoring Center repositories. The P-score was initially estimated using a simple method that involved calculating the difference between the observed and expected death counts. The interrupted time series analysis was then used to calculate the mean relative risk (RR) of death during the first year of the pandemic. RESULTS: Our study found that there were 5571 excess deaths from all causes (P-score=33.29%) during the first year of the COVID-19 pandemic, with 48.03% of these deaths directly related to COVID-19. The pandemic was found to increase the risk of death from all causes (RR, 1.26; 95% confidence interval [CI], 1.19 to 1.33), as well as in specific age groups such as those aged 35-49 (RR, 1.21; 95% CI, 1.12 to 1.32), 50-64 (RR, 1.38; 95% CI, 1.28 to 1.49), and ≥65 (RR, 1.29; 95% CI, 1.12 to 1.32) years old. Furthermore, there was an increased risk of death from cardiovascular diseases (RR, 1.17; 95% CI, 1.11 to 1.22). CONCLUSIONS: There was a 26% increase in the death count in southern Iran during the COVID-19 pandemic. More than half of these excess deaths were not directly related to COVID-19, but rather other causes, with cardiovascular diseases being a major contributor.

Factors associated with late initiation of antiretroviral therapy in Iran's HIV/AIDS surveillance data.

Early initiation of Antiretroviral Treatment (ART) in HIV patients is essential for effectively suppressing the viral load and prognosis. This study utilized National HIV/AIDS Surveillance Data in Iran to identify factors associated factors with the duration to initiate ART. This hybrid cross-sectional historical cohort study was conducted on Iran's National HIV/AIDS Surveillance Data from 2001 to 2019. Sociodemographic characteristics, route of transmission, HIV diagnosis date, and ART initiation date were collected. Multivariable linear and quantile regression models were employed to analyze the duration to initiate ART by considering predictor variables. This study included 17,062 patients (mean age 34.14 ± 10.77 years, 69.49% males). Multivariate quantile regression coefficients varied across different distributions of the dependent variable (i.e., duration to initiate ART) for several independent variables. Generally, male gender, injecting drug use (IDU), and having an HIV-positive spouse were significantly associated with an increased duration to initiate ART (p < 0.05). However, a significant decrease was observed in older patients, those with a university level education, men who had sex with men (MSM), and patients diagnosed after 2016 (p < 0.05). Despite improvements in the duration to initiate ART after implementing the WHO's 2016 program in Iran, various sociodemographic groups were still vulnerable to delayed ART initiation in the region. Therefore, programs including early testing, early ART initiation, active care, educational and cultural interventions, and appropriate incentives are required for these groups.

Duration of delayed diagnosis in HIV/AIDS patients in Iran: a CD4 depletion model analysis.

Objective: Delayed diagnosis of HIV can lead to an inappropriate response to antiretroviral therapy (ART), rapid progression of the disease, and death. It can also carry harmful effects on public health due to the increment of transmission. This study aimed to estimate the duration of delayed diagnosis (DDD) in HIV patients in Iran. Methods: This hybrid cross-sectional cohort study was conducted on the national HIV surveillance system database (HSSD). Linear mixed effect models with random intercept, random slope, and both were used to estimate the parameters required for the CD4 depletion model to determine the best-fitted model for DDD, stratified by the route of transmission, gender, and age group. Results: The DDD was estimated in 11,373 patients including 4,762 (41.87%) injection drug users (IDUs), 512 (4.5%) men who had sexual contact with men (MSM), 3,762 (33.08%) patients with heterosexual contacts, and 2,337 (20.55%) patients who were infected through other routes of HIV transmission. The total mean DDD was 8.41 ± 5.97 years. The mean DDD was 7.24 ± 0.08 and 9.43 ± 6.83 years in male and female IDUs, respectively. In the heterosexual contact group, DDD was obtained as 8.60 ± 6.43 years in male patients and 9.49 ± 7.17 years in female patients. It was also estimated as 9.37 ± 7.30 years in the MSM group. Furthermore, patients infected through other transmission routes were found with a DDD of 7.90 ± 6.74 years for male patients and a DDD of 7.87 ± 5.87 years for female patients. Conclusion: A simple CD4 depletion model analysis is represented, which incorporates a pre-estimation step to determine the best-fitted linear mixed model for calculating the parameters required for the CD4 depletion model. Considering such a noticeably high HIV diagnostic delay, especially in older adults, MSM, and heterosexual contact groups, regular periodic screening is required to reduce the DDD.

The effect of COVID-19 pandemic on diabetes care indices in Southern Iran: an interrupted time series analysis.

BACKGROUND: Type 2 diabetes mellitus (T2DM) requires a continues bulk of cares. It is very probable COVID-19 pandemic is affected its healthcare coverage. METHODS: The interrupted time series analysis is used to model the trend of diabetes healthcare indices, such as the health worker visits, physician visits, body mass index (MBI), fasting blood sugar (FBS), and hemoglobin A1c (HbA1c), before and after the start of COVID-19 pandemic. The reference of data was the totals of all T2DM patients living in Fars Province, Southern Iran, areas covered by Shiraz University of Medical Science (SUMS), from 2019 to 2020. RESULTS: A significant decrease for visits by the health workers, and physicians was observed by starting COVID-19 pandemic (ß2 = -0.808, P < 0.001, ß2 = -0.560, P < 0.001); Nevertheless, the coverage of these services statistically increased by next months (ß3 = 0.112, P < 0.001, ß3 = 0.053, P < 0.001). A same pattern was observed for the number of BMI, FBS and HbA1c assessments, and number of refer to hospital emergency wards (ß3 = 0.105, P < 0.001; ß3 = 0.076, P < 0.001; ß3 = 0.022, P < 0.001; ß3 = 0.106, P < 0.001). The proportion of T2DM patients with HbA1C < 7%, and controlled hypertension during study period was statistically unchanged. CONCLUSIONS: When the COVID-19 pandemic was announced, T2DM healthcare coverage drastically decreased, but it quickly began to rebound. The health monitoring system could not have any noticeable effects on diabetes outcomes.

Effect of the COVID-19 pandemic on maternal healthcare indices in Southern Iran: an interrupted time series analysis.

OBJECTIVES: Epidemics are anticipated to influence the coverage of health services. We assessed the impact of the COVID-19 pandemic on maternal healthcare indices and care providers' performance. SETTING: 1801 maternal healthcare centres under the auspices of Shiraz University of Medical Sciences, Shiraz, Southern Iran. PARTICIPANTS: Approximately 63 000 pregnant women. PRIMARY AND SECONDARY OUTCOME MEASURES: In this prospective ecological study, interrupted time series analysis was used to model and compare the trend of maternal healthcare indices before and after the COVID-19 pandemic announcement. RESULTS: The results showed a significant drop in count of preconception healthcare visits, first routine laboratory tests, first trimester prenatal care, first trimester sonography, prenatal screening for birth defects at weeks 11-13, prenatal care visits at weeks 16-20, second routine laboratory tests, second trimester sonography, prenatal care visits at weeks 24-30, prenatal care visits at weeks 31-34, postpartum care visits at days 10-15 and postpartum care visits at days 30-42 with the start of the COVID-19 pandemic (-50% (95% CI -48.68% to -51.36%), -19.67% (95% CI -22.12% to -17.15%), -25.88% (95% CI -28.46% to -23.21%), -23.84% (95% CI -26.26% to -21.34%), -20.16% (95% CI -23.01% to -17.20%), -18.53% (95% CI -21.25% to -15.71%), -28.63% (95% CI -31.03% to -26.14%), -27.48% (95% CI -30.07% to -24.79%), -31.08% (95% CI -33.43% to -28.61%), -31.84% (95% CI -34.35% to -29.23%), 32.55% (95% CI -35.12% to -29.89%) and -39.28% (95% CI -41.59% to -36.88%), respectively). Nevertheless, the trend in coverage of these services showed recovery in the subsequent months (8.36%, 10.55%, 5.74%, 8.01%, 4.40%, 5.06%, 11.20%, 7.58%, 7.38%, 7.80%, 9.59% and 9.61% per month, respectively). CONCLUSIONS: Using ecological data during the COVID-19 pandemic era, we observed a 'level change and slope change' as the major pattern of interruption of maternal healthcare coverage, indicating a possible indirect effect rather than a causative relationship. Such relative predictability might assist with future pandemic planning.

Prevalence of diabetic retinopathy in the Eastern Mediterranean Region: a systematic review and meta-analysis.

OBJECTIVES: Individual studies in the Eastern Mediterranean Region (EMR) have shown the high prevalence of diabetic retinopathy. We conducted a meta-analysis to yield an estimate of the prevalence of diabetic (type 1 and 2) retinopathy in the EMR. Additionally, we explored its potential modulators. METHODS: Two-step screening of relevant articles published from 1 January 2000 to 13 December 2019 was carried out. An estimation of summary proportions, subgroup analysis, meta-regression, and publication bias assessment were performed. RESULTS: One hundred nine articles were included in the meta-analysis, involving 280,566 patients. The prevalence of diabetic retinopathy was 31% (95% confidence interval [CI] = 28, 33). The highest and lowest diabetic retinopathy prevalence rates were observed in low human development index (HDI) countries (63.6; 95% CI = 52.4, 74.0) and very high HDI countries 22.6 (95% CI = 20.5, 24.7), respectively. CONCLUSIONS: The prevalence of diabetic retinopathy is high in the EMR. Our results provide important information for diverse healthcare surveillance systems in the EMR to implement the modifiable risk factors, diabetes screening to decrease undiagnosed diabetes, early detection of retinopathy, and proper diabetes care to decrease untreated diabetes.

The Association of Opium Abuse with Mortality Amongst Hospitalized COVID-19 Patients in Iranian Population.

Opioid abuse is a serious problem in the society. Since the first months of COVID-19 pandemic, several myths, rumors and misconceptions have been spread about the benefits of opium consumption for COVID-19 outcome. In addition, data are limited on the relationship between opium abuse and COVID-19 mortality amongst hospitalized COVID-19 patients. In this historical cohort study, we assessed the risks of several variables for mortality amongst all hospitalized COVID-19 patients from the beginning of COVID-19 pandemic in South of Iran from March 15th, 2021 to October 14th, 2021. Data was acquired from the Medical Care Monitoring Center (MCMC), affiliated to Shiraz University of Medical Sciences. A total of 64,427 hospitalized COVID-19 patients were included into the analysis. The mortality rate was 10.59% (n = 6756). Of all, 2030 (3.15%) patients-1702 males and 328 females-reported the positive history of opium abuse with a mean age of 57 ± 17.21 years. The results of multivariable risk showed that the positive history of opium abuse had a significant association with mortality (adjusted RR: 1.173; p = 0.007). Other significant predictive risk factors were male gender, elder ages, and comorbidities such as pulmonary diseases, cardiovascular disease, cancer, nephrological diseases, neurological diseases, and diabetes. However, being a health care worker and having thyroid gland diseases were protective factors amongst hospitalized COVID-19 patients (adjusted RR: 0.650 and 0.642; p = 0.040 and < .0001, respectively). Opium abuse is a risk factor for mortality amongst hospitalized COVID-19 patients. It is vital to educate societies about the consequences of unauthorized opium consumption.

Efficacy of single-dose and double-dose ivermectin early treatment in preventing progression to hospitalization in mild COVID-19: A multi-arm, parallel-group randomized, double-blind, placebo-controlled trial.

BACKGROUND AND OBJECTIVE: Ivermectin is a known anti-parasitic agent that has been investigated as an antiviral agent against coronavirus disease 2019 (COVID-19). This study aimed to evaluate the efficacy of ivermectin in mild COVID-19 patients. METHODS: In this multi-arm randomized clinical trial conducted between 9 April 2021 and 20 May 2021, a total of 393 patients with reverse transcription-PCR-confirmed COVID-19 infection and mild symptoms were enrolled. Subjects were randomized in a 1:1:1 ratio to receive single-dose ivermectin (12 mg), double-dose ivermectin (24 mg) or placebo. The primary outcome was need for hospitalization. RESULTS: There was no significant difference in the proportion of subjects who required hospitalization between the placebo and single-dose ivermectin groups (absolute difference in the proportions: -2.3 [95% CI = -8.5, 4.1]) and between the placebo and double-dose ivermectin groups (absolute difference in the proportions: -3.9 [95% CI = -9.8, 2.2]). The odds of differences in mean change in severity score between single-dose ivermectin and placebo groups (ORdifference  = 1.005 [95% CI: 0.972, 1.040]; p = 0.762) and double-dose ivermectin and placebo groups (ORdifference  = 1.010 [95% CI: 0.974, 1.046]; p = 0.598) were not statistically significant. None of the six adverse events (including mild dermatitis, tachycardia and hypertension) were serious and required extra action. CONCLUSION: Single-dose and double-dose ivermectin early treatment were not superior to the placebo in preventing progression to hospitalization and improving clinical course in mild COVID-19.

Effectiveness of Coronavirus Disease 2019 Vaccines in Preventing Infection, Hospital Admission, and Death: A Historical Cohort Study Using Iranian Registration Data During Vaccination Program.

Background: There are some concerns about the effectiveness of the inactivated and vector-based vaccines against severe acute respiratory syndrome coronavirus 2 in real-world settings with the emergence of new mutations, especially variants of concern. Data derived from administrative repositories during mass vaccination campaigns or programs are of interest to study vaccine effectiveness. Methods: Using 4-repository administrative data linkage, we conducted a historical cohort study on a target population of 1 882 148 inhabitants aged at least 18 years residing in southern Iran. Results: We estimated a 71.9% [95% confidence interval [CI], 70.7%-73.1%], 81.5% [95% CI, 79.5%-83.4%], 67.5% [95% CI, 59.5%-75.6%], and 86.4% [95% CI, 84.1%-88.8%] hospital admission reduction for those who received the full vaccination schedule of BBIBP-CorV (Sinopharm), ChAdOx1-S/nCoV-19 vaccine (AZD1222, Oxford-AstraZeneca), rAd26-rAd5 (Gam-COVID-Vac, Sputnik V), and BIV1-CovIran (COVIran Barekat) vaccines, respectively. A high reduction in mortality (at least 85%) was observed in all age subgroups of the fully immunized population. Conclusions: The pragmatic implementation of a vaccination plan including all available vaccine options in the Iranian population was associated with a significant reduction in coronavirus disease 2019 (COVID-19) detected infections as well as hospital admissions and deaths associated with COVID-19.

Comparison of Male and Female Sexual Dysfunction between Hemodialysis and Peritoneal Dialysis in Patients with End-Stage Renal Disease: An Analytical Cross-Sectional Study.

Background: Maintenance dialysis is the most common treatment for end-stage renal disease (ESRD) patients. One of the most ignored but important health issue among dialysis patients is sexual dysfunction, which interferes with quality of life (QoL). Studies showed that the side effects of the two conventional methods of dialysis (hemodialysis (HD) and peritoneal dialysis (PD)) are different on a patient's health. Therefore, we sought to compare the sexual dysfunction score, both male and female, between patients undergoing HD and PD. Methods: One hundred seventy adults (85 HD and 85 PD) subject with end-stage renal disease (ESRD) on dialysis for at least 2 months were included. For male subjects, the erectile function (EF) domain of the International Index of Erectile Function (IIEF) questionnaire was calculated. Moreover, the Female Sexual Function Index (FSFI) questionnaire was calculated for females. Data were analyzed via SPSS software. Two independent sample t-test with two-sided significance level of 5% was used for comparing the sexual dysfunction score between HD and PD patients. Results: Out of 170 patients with mean age of 49.34 ± 11.7 years, 52.9% were female. Better sexual function scores were obtained in the HD group's females for desire, orgasm, and satisfaction domains, as well as the total score (P = 0.03, 0.016, 0.02, and 0.039, respectively). The erectile function was significantly better in the PD group's males (P). Conclusion: We found better sexual life in the HD group's females and PD group's males. Considering dialysis as a life-long treatment of CKD patients, this part of a patient's life must be taken seriously by the healthcare providers to choose the most suitable method for patients based on their personalized conditions.

A descriptive report on short QT interval in Kherameh branch of the PERSIAN cohort study.

Short QT-interval is a condition that bear the suspicion of short QT syndrome (SQTS). SQTS is known to increase risk of life-threatening arrythmias and sudden cardiac death (SCD). Due to the insufficient population-based studies and use of various QT cut-off values, it accounts for as an undiagnosed condition. In this study, we sought for prevalence of short QT interval in Kherameh cohort study, one of the southern branches of the Prospective Epidemiological Research Studies in Iran (PERSIAN). Data of 4363 adult subjects were analyzed from phase 1 of the cohort during 2014-2017. The corrected QT (QTc) intervals were calculated and electrocardiograms (ECGs) with QTc of less than 370 ms (msec) were reanalyzed for bradycardia, early repolarization, atrial fibrillation (AF), arrhythmias, and other electrical conduction abnormalities. Seventy-two subjects (1.65%) had a QTc of less than 370 ms (mean QTc of 360.72 ± 11.72). A male predominance and a lower mean heart rate observed in SQTS susceptible group (M/F of 1/0.26 vs. 1/1.145, p-value < 0.0001; 58.389 ± 9.787 vs. 70.899 ± 11.775; p-value < 0.0001) compare to the subjects with normal QTc. At least, 2 subjects with high-probability SQTS and 3 with intermediate-probability SQTS identified. The frequency of AF, syncope, bradycardia, early repolarization, low voltage ECG, and infantile SCD in first- and second-degree relatives were 16.67, 4.17, 33.33, 11.11, 11.11, 11.11%, respectively. The prevalence of short QT interval in our cohort was in line with previous studies. The incidence of cardiac symptoms/events, familial SCDs and ECG derived specific findings were high amongst SQTS-susceptible index persons. However, these variables could not predict the symptomatic subjects, which emphasizes gene studies and family screening.

Efficacy of herbal treatments for functional dyspepsia: A systematic review and meta-analysis of randomized clinical trials.

Functional dyspepsia (FD) is a very common condition globally. Relevant keywords were searched for in title and abstract of selected databases, that is, Medline/PubMed, Scopus, Embase, Web of knowledge, and Google Scholar. Placebo and active-control trials on herbal remedies amongst adults who were diagnosed with FD were included. Dichotomous outcomes were presented as relative risk (RR) with 95% confidence interval (CI) and continuous outcomes were presented as pooled standardized mean difference (SMD) with 95% CI. Forty-nine randomized controlled trials (RCTs) were entered into meta-analysis (6,987 subjects). Herbal remedies resulted in a higher improvement in FD symptoms in comparison with the placebo (SMD = -0.58 [-0.66- -0.51], p < .00001 and RR = 1.73 [1.62-1.85], p < .00001). No significant difference between herbal remedies and placebo in the incidence of adverse events was observed (12.27 vs. 8.41%, RR = 1.06 [0.91-1.23], p = .45). Also, herbal remedies resulted in a higher improvement in quality of life in comparison with placebo (SMD = -0.64 [-0.73- -0.55], p < .00001). When comparing herbal remedies with conventional medicine through sensitivity analysis, no outcomes were significantly different (p > .05). Herbal remedies might be efficacious and safe in treating FD, and demonstrate comparable effect sizes for efficacy to conventional treatments. Further high-quality studies are warranted to firmly establish the clinical efficacy of the herbal remedies.

Efficacy of topical cysteamine hydrochloride in treating melasma: a systematic review.

INTRODUCTION: Melasma remains a recurrent, chronic, therapeutically challenging, and psychologically burdening condition. Several different modalities and approaches have been utilized, and some with notable success to experimentally manage the condition. Cysteamines, with their depigmentation properties, have only recently been intensely studied. One such formulation is the topical 5% cysteamine hydrochloride, the structure of which is notably more stable and with a less foul odor than its prior counterparts. We, therefore, aimed to assess the efficacy of the mentioned formulation in the treatment of melasma. METHODS: The PubMed, SCOPUS, ISI Web of Science, and Embase, Cochrane, and Proquest databases were thoroughly searched for English studies evaluating the effects of the topical agent mentioned. RESULTS: Eight studies (five RCTs, two case reports, and one case series) were included after three rounds of screening, most of which were carried out in Iran. Statistical significance was noted when assessing decreased melanin content and satisfaction rates. CONCLUSIONS: It appears that the cysteamine cream could be comparably efficient in treating melasma while accompanied only by minor and transient adverse events. However, current evidence is limited by insufficient sample size, long-term follow-up, and only to epidermal melasma, highlighting the need for appropriately designed randomized controlled clinical trials to draw a conclusive image of the cysteamine's role in treating this recalcitrant condition.

Estimating the prevalence and incidence of treated type 2 diabetes using prescription data as a proxy: A stepwise approach on Iranian data.

AIMS: Type 2 diabetes is a serious health challenge, and large-scale studies on its prevalence in Iran are lacking. In pharmacoepidemiology, case-finding can be done by reviewing the prescription databases for specific drug(s) prescribed for a disease. We aimed to determine the prevalence and incidence of type 2 diabetes in Fars province, Iran, using prescription data and a stepwise approach to ascertain the results. METHODS: A dataset of 3,113 insured individuals aged ≥35 years were selected. Their Prescription Data Centre records were reviewed for all drugs frequently used in controlling type 2 diabetes available in the Iranian pharmacopeia. Then we used a stepwise method for case-finding. In step one, each individual with a positive drug history for type 2 diabetes was labeled as an individual with diabetes. The next two steps were implemented for ascertainment of step one estimations. RESULTS: Prevalence of type 2 diabetes based on prescription, internist opinion, and phone call verification in 2015 and 2016 was 9.3% and 10.3%, 8.5% and 9.8%, and 7.2% and 8.7%, respectively. An incidence of 1.9% was determined for 2016. CONCLUSIONS: We obtained a realistic estimation of prevalence and incidence of treated type 2 diabetes, using prescription data which are large-scale, low cost, and real-time.

Diagnosis of Latent Tuberculosis in Liver Transplant Candidates, a Single Center Experience.

BACKGROUND: Tuberculosis is an important cause of mortality and morbidity in liver transplant patients, so it is valuable to diagnose latent tuberculosis in liver transplant candidates by an accurate screening test prior to transplantation. Tuberculin skin test (TST) is the standard test for the diagnosis of latent tuberculosis. Currently interferon-gamma release assays (QuantiFERON-TB Gold (QFT)) have been proposed as the best screening test, especially in the geographic areas with widespread BCG vaccination. In this research, we will compare these two tests in the largest liver transplant center in the south of Iran. METHODS: Both TST and QFT were performed in 50 liver transplant patients and 50 normal healthy individuals. RESULTS: TST was positive in 6 cases and 4 controls. QFT was positive in 5 cases and 9 controls. Sensitivity and negative predictive value were higher in QFT but the specificity and positive predictive value were higher in TST. CONCLUSIONS: There is no significant difference between QFT and TST in evaluation of latent tuberculosis in liver transplant patients, however TST is less expensive and more feasible in Iran.

Family dermatology life quality index in patients with pemphigus vulgaris: A cross-sectional study.

BACKGROUND AND AIMS: Pemphigus vulgaris is a rare autoimmune intraepidermal vesiculobullous disease involving the skin and mucosa. It impacts the quality of life of both patients and their families. METHODS: A total of 70 patients with pemphigus vulgaris (either outpatient or hospitalized) were enrolled using the simple sampling method between 2016 and 2017 from the dermatology clinic at Faghihi Hospital, Shiraz, Iran. A validated Persian version of the Family Dermatology Life Quality Index (FLDQI) questionnaire was filled by a family caregiver. The questionnaire contained 10 items assessing the quality of life of the family. Demographic variables were recorded in a separate form. RESULTS: The mean age of the patients was 51 ± 11.3 years and that of the family caregivers was 32 ± 8.8 years. The FLDQI score was higher (poorer quality of life) if the patient was male, older, had shorter disease duration or had fewer disease recurrences (P = 0.046, 0.01, 0.001 and >0.001, respectively). Higher scores were also obtained in the less-educated caregivers (P = 0.026) but there was no association with either gender or age (P = 0.399, 0.1). CONCLUSION: Pemphigus vulgaris significantly affects the Family Dermatology Life Quality Index. Education and counseling of family caregivers by various support groups such as Pemphigus Family Associations could be effective in improving the quality of life of the caregivers. LIMITATIONS: This study did not assess the effect of comprising domain analysis, severity of disease, patients' Dermatology Life Quality Index (DLQI), mucosal involvement, response to treatment, outpatient or admitted status, socioeconomic status, or the quality of life among the various family members.
