Determinants and economic burden of HIV/AIDS in Iran: a prospective study.

BACKGROUND: Since the start of the AIDS outbreak, the human immunodeficiency virus (HIV) has infected about 84.2 million people, and approximately 40.1 million people have died due to AIDS-related diseases. So, this study aims to provide a comprehensive population-based description of patient costs and the economic burden of HIV/AIDS in Iran. METHODS: The study population of this cross-sectional cost-of-illness study consisted of HIV-infected patients who were receiving services in Mashhad and were under the supervision of BIDCC. There are four BIDCC centers in Mashhad, we considered all patients referred to these centers. Costs data were evaluated from a social perspective with a bottom-up approach and as a prevalence based. The data from 157 individuals were included in the study. For collecting data on direct and indirect costs belonging to patients and their families, a questionnaire was developed. Also, the Demographic characteristic of participants and the stage of the disease and Transmission category were analyzed. RESULTS: In this study, 57.32 of the subjects were Male. The majority of participants in this study were in the age group 30-59 years (n = 124,78.98%). Based on where the patients live, the majority of patients have lived in the urban region (n = 144, 91.72%). The most common way to transmit this disease is through unprotected sex (30.57%) and then Infected spouse (28.03%), and then injecting drugs (21.02%). The highest cost of this disease is attributed to medicine (10339.32 $ for 6 months), after medicine, the cost of tests was 9101.22 $. CONCLUSION: It seems that to reduce costs for patients with disease HIV/AIDS, the focus should be on diagnostic tests and care. Early diagnosis and rapid initiation of antiviral treatments can be effective in preventing serious and debilitating diseases.

Hs-CRP and TNF-α Effects on Postnatal Umbilical Coiling: Impact Assessment of the Gestational Diabetes Mellitus.

Background: No study has been conducted to specifically demonstrate the relationship between gestational diabetes mellitus (GDM) status, inflammatory factors, and postnatal umbilical coiling index (pUCI). Understanding this relationship could help select the best interventions to save the fetus. To evaluate the effects of maternal venous and umbilical cord blood levels of high sensitivity C-reactive protein (hs-CRP) and tumor necrosis factor-alpha (TNF-alpha) on pUCI in GDM and non-GDM groups. Methods: This prospective observational study included 40 participants in each of the GDM and non-GDM groups, matched for maternal age, ethnicity, and parity. The GDM diagnosis was confirmed by 24 to 28 weeks of gestation (WOG) and a 2-step strategy. The covariates of interest were maternal hs-CRP and TNF-α, measured at 37 to 40 WOG, and their UC analogous was measured during delivery. The gross morphologies were assessed immediately after delivery. The UC coiling was quantitatively assessed by the pUCI. To compare the GDM and non-GDM groups, the t test and the Mann-Whitney test were used for normal and non-normal variables, respectively. Results: There was not a significant difference in hs-CRP and TNF-a levels in maternal venous blood or UC blood between the GDM and non-GDM groups. The mean (SD) of pUCI in the GDM and non-GDM groups were 0.28 (0.15) and 0.24 (0.21) (P = 0.441), respectively. In the GDM group, none of the 4 covariates of interest had significant effects on the UCI. Among the non-GDM participants, merely the UC hs-CRP had a direct association with the pUCI, with a Pearson correlation of 0.54 (P = 0.001). Impacts of hs-CRP and TNF-α on the pUCI were assessed using Poisson regression models and no significant findings were detected (95% CI, 0.999-1.001, for all parameters). Conclusion: In the GDM group, no apparent association was observed between inflammatory factors and pUCI, although a direct association was detected between UC hs-CRP and pUCI in the non-GDM.

Association of monocyte/high-density lipoprotein cholesterol ratio and the carotid intima-media thickness in diabetic patients.

OBJECTIVES: The goal of this study was to see whether there was a link between the monocyte/high-density lipoprotein cholesterol ratio (MHR) and carotid intima-media thickness (CIMT) in people with type 2 diabetes. METHODS: Duplex ultrasonography parameters and demographic, physical, and paraclinical assessments were recorded. Using the t-test, the MHR and CIMT were compared between the two groups. Regression models were also constructed. RESULTS: A total of 118 diabetics and 126 non-diabetics were included in the cross-sectional research. According to the stated diabetes duration, the observed age difference of 7 years might be considered. The MHR and CIMT were not substantially different between the two groups. In the DM and non-DM groups, the Spearman correlations between MHR and CIMT were 0.32 and - 0.08, respectively (p-values = 0.001 and 0.379). Thus, regression models (stratified for DM/non-DM and male/female) revealed that the MHR is a significant predictor of CIMT, but only in the case of male DM individuals, when crudely adjusted for confounders. CONCLUSIONS: In diabetes mellitus, the current investigation found a direct link between MHR and CIMT. In addition, in male diabetic subjects, MHR was demonstrated to be a predictor of CIMT.

Post-treatment heterogeneity of cardiometabolic risk in patients with acromegaly: The impact of GH and IGF-1.

BACKGROUND: Metabolic abnormalities are frequently seen in patients with acromegaly. However, it is not clear to what extent growth hormone/insulin-like growth factor-1 (GH/IGF-1) contributes to the development of these abnormalities. OBJECTIVE: This study aimed to explore the impact of postoperative GH/IGF-1 on different aspects of metabolic abnormalities in patients with acromegaly. METHODS: This retrospective, registry-based study conducted on 102 patients with acromegaly. The impact of GH/IGF-1 on the cardiometabolic risk factors at 3-12 months after surgery has been investigated using linear and logistic regression models. RESULTS: In this study, each 1 ng/ml increase in the level of GH was significantly associated with a 2 mg/dl increase in the level of fasting blood glucose (FBG), a 0.5 mmHg increase in the level of systolic blood pressure (SBP), and a 0.9 mmHg increase in the level of diastolic blood pressure (DBP). Upon multivariate analysis, GH, but not IGF-1, significantly increased the odds of diabetes mellitus (DM) (OR; 1.2, 95% CI; 1.0-1.4, p = .025). CONCLUSIONS: Our findings indicated at early postoperative stage, GH is significantly associated with the levels of FBG, SBP, and DBP. Moreover, GH, but not IGF-1, appears as a predictive factor for the presence of DM. However, neither GH nor IGF-1 could predict the presence of hypertension HTN, or dyslipidemia in this study. ABBREVIATIONS: CVD: Cardiovascular disease; GH: Growth hormone; IGF-1: Insulin-like growth factor 1; BMI: Body mass index; HTN: hypertension; IPTR: Iran Pituitary Tumor Registry; WC: Waist circumference; MRI: Magnetic resonance imaging; FBG: Fasting blood glucose; HbA1C: Glycated hemoglobin; TG: Triglyceride; LDL: Low density lipoprotein; HDL: High density lipoprotein; SBP: Systolic blood pressure; DBP: Diastolic blood pressure.

Hospital-acquired infections in a tertiary hospital in Iran before and during the COVID-19 pandemic.

Infection prevention protocols are the accepted standard to control nosocomial infections. These protective measures intensified after the coronavirus 2019 (COVID-19) pandemic to reduce the risk of viral transmission. It is the rationale that this practice reduces nosocomial infections. We evaluated the impact of these protective measures on nosocomial infections in our center with more than 20,000 records of annual patient admission. In a retrospective study, we evaluated the incidence of nosocomial infections in Sina hospital for 9 months (April-December 2020) during the COVID-19 period and compared it with the 8 months in the pre-COVID period (April-November 2019). Despite decreasing the number of admissions during the COVID era (hospitalizations showed a reduction of 43.79%), the total hospital nosocomial infections remained unchanged; 4.73% in the pre-COVID period versus 4.78% during the COVID period. During the COVID period the infection percentages increased in the cardiovascular care unit (p-value = 0.002) and intensive care units (p-value = 0.045), and declined in cardiology (p-value = 0.046) and neurology (p-value = 0.019) wards. This study showed that intensifying the infection prevention protocols is important in decreasing the nosocomial infections in some wards (cardiology and neurology). Still, we saw increased nosocomial infection in some wards, e.g., the intensive care unit (ICU) and coronary care unit (CCU). Thus, enhanced infection prevention protocols implemented in hospitals to prevent the spread of a pandemic infection may not always decrease rates of other hospital-acquired infections during a pandemic. Due to limited resources, transfer of staff, and staff shortage due to quarantine measures may prohibit improved prevention procedures from effectively controlling nosocomial infections.

Trends of Diabetes Mortality in Iran at National and Sub-National Levels from 1990 to 2015 and Its Association with Socioeconomic Factors.

Background: Following global commitments to prevent and control non-communicable diseases, we sought to estimate national and sub-national trends in diabetes mortality in Iran and assess its association with socioeconomic factors. Methods: In a systematic analytical study, to assess the correlation between diabetes mortality and socioeconomic factors, we used data obtained from the Death Registration System (DRS), the Spatio-temporal model and Gaussian Process Regression (GPR) levels and the diabetes mortality trends, which were estimated by sex, age and year at national and sub-national levels from 1990 to 2015. Results: Between the years 1990 and 2015, the age-standardized diabetes mortality rate (per 100,000) increased from 3.40 (95% UI: 2.33 to 4.99) to 7.72 (95% UI: 5.51 to 10.78) in males and from 4.66 (95% UI: 3.23 to 6.76) to 10.38 (95% UI: 7.54 to 14.23) in females. In 1990, the difference between the highest age-standardized diabetes mortality rate among males was 3.88 times greater than the lowest (5.97 vs. 1.54), and in 2015 this difference was 3.96 times greater (14.65 vs. 3.70). This provincial difference was higher among females and was 5.13 times greater in 1990 (8.41 vs. 1.64) and 5.04 times greater in 2015 (19.87 vs. 3.94). The rate of diabetes mortality rose with urbanization yet declined with an increase in wealth and years of schooling as the main socio-economic factors. Conclusion: The rising trend of diabetes mortality rate at the national level and the sub-national disparities associated with socioeconomic status in Iran warrant the implementation of specific interventions recommended by the '25 by 25' goal.

Prevalence and determinants of diabetes and prediabetes in southwestern Iran: the Khuzestan comprehensive health study (KCHS).

BACKGROUND: The Middle East and North Africa (MENA) is postulated to have the highest increase in the prevalence of diabetes by 2030; however, studies on the epidemiology of diabetes are rather limited across the region, including in Iran. METHODS: This study was conducted between 2016 and 2018 among Iranian adults aged 20 to 65 years residing in Khuzestan province, southwestern Iran. Diabetes was defined as the fasting blood glucose (FBG) level of 126 mg/dl or higher, and/or taking antidiabetic medications, and/or self-declared diabetes. Prediabetes was defined as FBG 100 to 125 mg/dl. Multinomial logistic regression models were used to examine the association of multiple risk factors that attained significance on the outcome. RESULTS: Overall, 30,498 participants were recruited; the mean (±SD) age was 41.6 (±11.9) years. The prevalence of prediabetes and diabetes were 30.8 and 15.3%, respectively. We found a similar prevalence of diabetes in both sexes, although it was higher among illiterates, urban residents, married people, and smokers. Participants aged 50-65 and those with Body Mass Index (BMI) 30 kg/m2 or higher were more likely to be affected by diabetes [RR: 20.5 (18.1,23.3) and 3.2 (3.0,3.6)]. Hypertension [RR: 5.1 (4.7,5.5)], waist circumference (WC) equal or more than 90 cm [RR: 3.6 (3.3,3.9)], and family history [RR: 2.3 (2.2,2.5)] were also significantly associated with diabetes. For prediabetes, the main risk factors were age 50 to 65 years [RR: 2.6 (2.4,2.8)], BMI 30 kg/m2 or higher [RR: 1.9 (1.8,2.0)], hypertension and WC of 90 cm or higher [RR: 1.7 (1.6,1.8)]. The adjusted relative risks for all variables were higher in females than males, with the exception of family history for both conditions and waist circumference for prediabetes. CONCLUSIONS: Prediabetes and diabetes are prevalent in southwestern Iran. The major determinants are older age, obesity, and the presence of hypertension. Further interventions are required to escalate diabetes prevention and diagnosis in high-risk areas across Iran.

Impaired fasting glucose and major adverse cardiovascular events by hypertension and dyslipidemia status: the Golestan cohort study.

BACKGROUND: Whether pre-diabetes in the absence of hypertension (HTN) or dyslipidemia (DLP) is a risk factor for occurrence of major adverse cardiovascular events (MACE) is not fully established. We investigated the effect of impaired fasting glucose (IFG) alone and in combination with HTN, DLP or both on subsequent occurrence of MACE as well as individual MACE components. METHODS: This longitudinal population-based study included 11,374 inhabitants of Northeastern Iran. The participants were free of any cardiovascular disease at baseline and were followed yearly from 2010 to 2017. Cox proportional hazard models were fitted to measure the hazard of IFG alone or in combination with HTN and DLP on occurrence of MACE as the primary endpoint. RESULTS: Four hundred thirty-seven MACE were recorded during 6.2 ± 0.1 years follow up. IFG alone compared to normal fasting glucose (NFG) was not associated with an increase in occurrence of MACE (HR, 0.87; 95% CI, 0.19-4.02; p, 0.854). However, combination of IFG and HTN (HR, 2.88; 95% CI, 2.04-4.07; p, 0.000) or HTN + DLP (HR, 2.98; 95% CI, 1.89-4.71; p, 0.000) significantly increased the risk for MACE. Moreover, IFG + DM with or without HTN, DLP, or both was also associated with an increase in the incidence of MACE. CONCLUSION: IFG, per se, does not appear to increase hazard of MACE. However, IFG with HTN or HTN + DLP conferred a significant hazard for MACE in an incremental manner. Moreover, IFG without HTN, adjusted for DLP, can be associated with an increase in the risk for CVD- death.

Knowledge of physicians regarding the management of Type two Diabetes in a primary care setting: the impact of online continuous medical education.

BACKGROUND: To explore the impact of an online continuing medical education (CME) program on physicians' knowledge about the management of type two diabetes. METHODS: An online CME program was designed and uploaded in the CME platform, Department of Education, Ministry of health, Iran. A 28-item questionnaire was used for the assessment. In the beginning, a case scenario was introduced. Then, participants were asked to follow and answer to a pretest assessment. Details of the educational content were provided afterward. Finally, the participants took part in the same post-test exam 4 weeks later. The Wilcoxon matched-pairs signed-ranks test was used to compare the measurements. In addition, the Mann-Whitney test was applied to compare knowledge indices between the general practitioners (GPs) and internists. RESULTS: Five hundred twenty-six primary care physicians participated in this study. There was a significant positive effect regarding diagnosis confirmation (10.3% difference, P = 0.0001). Moreover, a smaller effect was observed in relation to the importance of glycosylated hemoglobin (HbA1c) at diagnosis (5.2% difference, P = 0.0006). The effect was positive in relation to the self-reported HbA1c testing frequency: more than 90% of the participants answered correctly in the post-test exam (7.6% difference, P = 0.0001). Considering improved knowledge in the treatment of diabetes, there was a very significant difference in response to questions targeting advice on a healthy diet, and physical activity; 27.7% (P = 0.000), and 18.7% (P = 0.000), respectively. In addition, the program had a positive impact on various aspects of treatment with oral glucose-lowering drugs (OGLDs). Moreover, the intervention difference was 25, and 34.4% for the questions targeting the appropriate type of insulin, and insulin initiation regimen after OGLD failure. Subgroup analyses revealed that the intervention increased the rate of correct responses among the GPs in various domains of knowledge in diagnosis and treatment. The initial differences between the GPs and internists no longer remained significant after the intervention. CONCLUSION: Knowledge of Iranian primary health care professionals in diabetes management has significant shortcomings. This is concerning because they are at the front line of patient care. We demonstrate the effectiveness of online CME on improving GPs knowledge in the management of type 2 diabetes.

Assisted conception as a potential prognostic factor predicting insulin therapy in pregnancies complicated by gestational diabetes mellitus.

BACKGROUND: Advanced maternal age, family history of diabetes, pre-gestational obesity, increased level of HbA1c, history of gestational diabetes mellitus (GDM), and poor pregnancy consequences are considered risk factors for antenatal insulin requirement in women with GDM. However, the role of assisted reproductive technology (ART) in increasing the risk of insulin therapy in pregnancies complicated with GDM remained elusive. The current study aimed to determine the role of ART in predicting insulin therapy in GDM women and investigate the clinical and biochemical factors predicting the need for insulin therapy in pregnancies complicated with GDM. METHODS: In this prospective cohort study, 236 Iranian women with GDM were diagnosed by one-step oral glucose tolerance test (OGTT) between October 2014 and June 2017. They were mainly assigned to two groups; the first group (n = 100) was designated as ART which was further subdivided into two subgroups as follows: 60 participants who received medical nutrition therapy (MNT) and 40 participants who received MNT plus insulin therapy (MNT-IT). The second group (n = 136) was labeled as the spontaneous conception (SC), consisting of 102 participants receiving MNT and 34 participants receiving MNT in combination with IT (MNT-IT). The demographic, clinical, and biochemical data were compared between groups. Multivariate logistic regression was performed to estimate prognostic factors for insulin therapy. RESULTS: A higher rate of insulin therapy was observed in the ART group as compared with the SC group (40% vs. 25%; P < 0.001). Multivariate logistic regression demonstrated that maternal age ≥ 35 years [OR: 2.91, 95% CI: (1.28-6.62)], high serum FBS [1.10: (1.04-1.16)], HbA1c [1.91 (1.09-3.34)], and ART treatment [2.94: (1.24-6.96)] were independent risk factors for insulin therapy in GDM women. CONCLUSIONS: Apart from risk factors mentioned earlier, ART may be a possible prognostic factor for insulin therapy in pregnancies complicated with GDM.

Impact of rural family physician program on child mortality rates in Iran: a time-series study.

BACKGROUND: The rural family physician program and social protection scheme were started in Iran about 10 years ago, and no comprehensive study has been carried out to investigate the effects of this program on mortality-related health indicators yet. The present study aims to examine the impacts of implementation of the family physician program and rural insurance program, which was launched in June 2005, on neonatal (NMR), infant (IMR), and under-5-year (U5MR) mortality rates in rural areas of Iran between 1995 and 2011, using a time-series analysis. METHODS: Three segmented regression models were built to evaluate the effects of the program on NMR, IMR, and U5MR, and several independent variables were entered into the models, including annual incremental effect of the program (variable of interest), time effect, behvarz density, effect of the family physician and rural insurance programs, as well as socioeconomic variables including years of schooling, wealth index, sex ratio, and logarithmic scales of rural population size in each area. Data were gathered from secondary sources and other studies. Data pertaining to the year 2007 were excluded from the final analysis due to their inaccuracy. RESULTS: Our results show that the incremental effect of implementing the rural family physician program is associated with significant reductions in NMR (ß = - 0.341. p - value = 0.003) and IMR (ß = - 0.016. p - value = 0.009). Although the association between this effect and reductions in U5MR were evident, they were not statistically significant (ß = - 0.003. p - value = 0.542). Moreover, wealth status of inhabitants was associated with reductions in NMR (ß = - 0.889. p - value = 0.001), IMR (ß = - 0.052. p - value < 0.001), and U5MR (ß = - 0.055. p - value < 0.001) in the time period of the study. CONCLUSIONS: In this nationally representative study, we showed that implementation of the second health system reform in Iran, known as the family physician program and social protection scheme for rural inhabitants, is associated with significant reductions in NMR and IMR. However, reported reductions in U5MR were not found to be statistically associated with the launch of the program. The advantage of this study was the ability to depict a more precise picture of the outcomes of a national-level intervention.

Socioeconomic inequalities in neonatal and postneonatal mortality: Evidence from rural Iran, 1998-2013.

BACKGROUND: Over the past three decades, interventions have been implemented to reduce childhood mortality in Iran. Despite declines in overall mortality rates, inequalities in mortality across socioeconomic groups have remained unchanged. In this study, we assessed inequalities in infant mortality in rural regions of Iran. METHODS: We obtained data from the Iranian vital registration system, which includes data on 5,626,158 live births, 79,457 neonatal deaths, and 36,397 postneonatal deaths in rural areas of Iran over the course of a 16-year period, which was then divided into 4 four-year intervals. In addition to building multivariate regression models to identify factors associated with mortality, we calculated a concentration index for each province to measure inequalities in neonatal and postneonatal mortality, using wealth index as the socioeconomic variable of interest. We further assessed these inequalities as a component of their contributors by using the decomposition method. RESULTS: Although both neonatal (17.62 to 10.92) and postneonatal (8.11 to 5.14) mortality rates exhibited decreasing trends from 1998-2001 to 2010-2013, the inequalities observed in these indices remained nearly unchanged (concentration indices of -0.062 to -0.047 and -0.098 to -0.083, respectively). Furthermore, fraction of births occurred in hospitals and literate women contributed positively to the inequalities observed in both neonatal and postneonatal mortality rates, whereas the proportion of infants classified as low birth weight contributed negatively over all study periods. We also identified decreasing trends in inequalities of the proportion of infants classified as having low birth weight, being born in hospitals, being covered by health insurance, mothers' age, and literacy of women within the time intervals under study. CONCLUSIONS: Although infant mortality rates in Iran decreased over the studied time period, we observed notable inequalities in these measures. Several steps are needed to overcome these inequalities, including improving access to professional health services for lower income households, fairly distributing facilities and human resources, and improving insurance coverage to protect families from financial hardships. Moreover, social factors, such as literacy of women, were found to be important in decreasing inequalities in infant mortality. These steps require improving societal awareness of infant mortality and implementing improved and problem-oriented health policies.

Ambient Air Pollution and Incident Cardiovascular Disease in People with Type 2 Diabetes Mellitus: A cohort study.

OBJECTIVES: We aimed to assess the effect of air pollution on incident cardiovascular disease (CVD) in people with type 2 diabetes mellitus (T2DM). METHODS: We tracked 486 T2DM patients from 2012 to 2021. Cox regression models were applied to assess the hazard of exposure to particulate matter, carbon monoxide (CO), ozone, nitrogen dioxide, and sulfur dioxide (SO2) on incident CVD, revealing hazard ratios (HRs). RESULTS: CVD incidents occurred in 73 individuals. Among men, each 1-ppm increase in CO levels raised the risk of CVD (HR: 2.66 (95% CI: 1.30-5.44). For women, a 5-ppb rise in SO2 increased CVD risk (HR: 1.60 (95% CI: 1.11-2.30). No notable impact of particulate pollutants was found. CONCLUSIONS: Persistent exposure to gaseous air pollutants, specifically CO and SO2, is linked to the development of CVD in men and women with T2DM.

Evaluation of the Effects of Opium on the Expression of SOX2 and OCT4 in Wistar Rat Bladder.

BACKGROUND: Bladder cancer is a malignancy greatly affected by behavioral habits. The aim of this study was to examine the effect of opium on changes in the expression of OCT4 and SOX2 in the bladder tissue of rats. METHOD: Thirty six rats were divided into six groups: 24 rats in the addicted group received morphine and opium for 4 months with 12 rats in the control group. Blood testing was done for the evaluation of CBC, MDA, and TAC. The bladder tissue was removed and checked by histopathological examination. All total RNA was extracted, then cDNAs were synthesized and the OCT4 and SOX2 gene expressions were evaluated by Real-time PCR. RESULTS: The OCT4 mRNA expression level in the opium group of rats was significantly increased compared to the control group (13.5 and 6.8 fold in males and females respectively). Also, in the morphine group, similar augmentation was detected (3.8 and 6.7 fold in males and females respectively). The SOX2 mRNA over-expression level was seen in the morphine group of both genders as compared to the control group (3.7 and 4.2 fold in male and female respectively) but in the opium group, enhancement of mRNA level was seen only in males (6.6 fold). Opium increases both OCT4 and SOX2 expression more than morphine in male rats, but in female rats, SOX2 is increased more by morphine. CONCLUSION: Over expression of OCT4 and SOX2 was observed in rats treated with opium and morphine. Increased OCT4 and SOX2 expression was seen in opium-treated male rats, but in female rats, SOX2 was increased more by morphine.

Effects of the Surgical Ligation of the Ureter in Different Locations on the Kidney over Time in the Rat Model.

Purpose: To evaluate the effects of the surgical ligation of the ureter in different locations on the kidney over time in the rat model. Methods: A total of 155 rats were enrolled and randomly divided into the case (n = 150) and control (n = 5) groups. The case group included three separate groups (fifty rats in each group) that underwent surgical ureteral ligation at the proximal, middle, and distal ureter. The laboratory tests, and tumor necrosis factor α (TNF-α), were measured in groups. The pathological evaluation for glomerular changes, tubular dilation, interstitial fibrosis, and interstitial infiltration of the inflammatory cells following the obstruction was performed (severity of tubular atrophy categorized too mild (+), moderate (++), and severe (+++)). To compare the continuous variables between the groups and between the measurement times, the analysis of variance (ANOVA) was used. Results: Our results revealed that the creatinine four weeks after the obstruction was significantly higher in the proximal group obstruction (p value: 0.046). The three groups had no significant differences regarding urine creatinine, serum sodium, and serum TNF (p value: 0.261). Obstruction did not change the glomerular morphology in three intervention groups after six weeks. The commencing of severe tubular atrophy in proximal, middle, and distal ureteral obstruction was at weeks three, four, and six, respectively. Conclusion: The location of ureteral obstruction is also crucial in deciding to intervene to relieve the complete ureteral obstruction. Severe tubular damage occurs in weeks three, four, and six in proximal, middle, and distal ureteral obstruction, respectively.

Hypo-Albuminemia and Perioperative Renal Transplant-Related Infections: A Systematic Review and Meta-Analysis.

OBJECTIVE: to review the literature regarding the relationship between pre- and post-transplant hypo-Albuminemia with various renal transplant-related infections. MATERIALS AND METHODS: In a systematic review, we included the following keyword in the search: (Albumin*) AND (infection*) AND ("renal transplant" OR "renal transplantation" OR "renal transplants") OR ("kidney transplant" OR "kidney transplantation" OR "kidney transplants") OR "kidney grafting") with investigating databases including ProQuest, PubMed, Scopus, and Web of Science to May 2023. All adult patients who had renal transplantation were included. Albumin levels of infected (bacterial, fungal, or viral) patients and the type of infection should be reported in the included studies. The search strategy used in this review was reported by Preferred Reporting Items for Systematic Reviews and Meta-Analyses literature search extension (PRISMA-S). To conduct Meta-analyses, Stata version 17 was used. Also, DerSimonian-Laird random-effects models were used for this study. In our study, heterogeneity was quantified with I2 and τ2 statistics. inconsistency across studies is quantified by I2 statistics, and the impact of heterogeneity on the meta-analysis is assessed by this quantification. RESULTS: Overall, 18 studies were found to be reporting measures of association including risk ratio, odds ratio, and, hazard ratio. Among them, 10 and 8 studies were reporting bacterial and viral types of infection. The combined risk ratios were not statistically significant, in either type of infection. The mean (SD) of ages for bacterial and viral infections were found to be 45.3 (6.4) and 50.5 (7.6) years old, respectively. CONCLUSION: Hypoalbuminemia is not related to post-transplantation infections, and it seems that with adherence to proper pretransplant screening of recipients, vaccination, and post-transplant surveillance and prophylaxis, the impact of infections may be reduced.

Effect of theophylline on stent-related symptoms in patients undergoing Double-J ureteral stent insertion: a randomized controlled trial.

PURPOSE: To investigate the effect of oral theophylline on stent-related syndrome (SRS) after Double-J insertion. BACKGROUND: Double-J stent is widely using in many urological procedures. Infection, hematuria, and discomfort are some of common complication after stenting. Theophylline is a dimethylated xanthine that inhibits phosphodiesterase and blocks adenosine receptors. To relaxing effect of theophylline on smooth muscles and its effects on the urinary system, it seems it could reduce complications after inserting Double-J stent especially ureteral stent syndrome. METHOD: In this double-blind placebo-controlled randomized clinical trial, 67 patients were enrolled. Mean (SD) age of control and theophylline group was 51.8 (12.5) and 43.9 (10.4) years old, respectively. Patients were randomized into two groups of control and theophylline. All patients were stenting with silicon Double J. Theophylline group received 100 mg of theophylline, twice daily for 30 days, while control group received placebo. Stent symptoms were assessed by questionnaire and urine culture was performed before stent removal at removal day. Statistical analysis was performed using Chi-squared test and t test with P < 0.05 considered significant. Logistic regression models were fitted, crudely and adjusted for age and sex. RESULT: Of 67 eligible patients, 60 completed the study. Theophylline significantly decreased percentages of gross hematuria (P < 0.001), dysuria (P < 0.001), and urinary frequency (P < 0.001). Microscopic hematuria (P = 0.042) and chills (P = 0.042) also decreased after theophylline. CONCLUSION: Theophylline could be an effective and safe choice for reducing SRS among patients undergoing Double-J stent insertion.

The impact of long-term exposure to PM10, SO2, O3, NO2, and CO on incident dysglycemia: a population-based cohort study.

To examine the associations between long-term exposure to five major air pollutants including SO2, PM10, O3, NO2, and CO, and incident dysglycemia, impaired fasting glucose (IFG), and diabetes, separately. A total of 4254 (1720 men) normoglycemic individuals aged 20-69 years at baseline were followed from 2001 to 2018 every 3 years. To measure the long-term hazards of air pollutants for incident dysglycemia, the Weibull proportional hazards models for every 10-unit increment adjusted for diabetes risk factors were fitted. The air pollutants were put in the models in the form of averages of 1-, 2-, and 3-year periods. During a median follow-up of 12.2 years, we observed 1780 dysglycemia events. In contrast to NO2, the increase in SO2, O3, and PM10 levels were significantly associated with a higher risk of dysglycemia and IFG in all time spans excluding PM10 at 2 years. The largest hazard ratios for incident dysglycemia and IFG were attributable to PM10 in 3 years (2.20 (95% CI 1.67, 2.89) and 2.08 (1.55, 2.80), respectively). Moreover, exposure to all the pollutants except NO2 in 1 year (0.89 (0.80, 0.98)) had no significant associations with incident diabetes. There was a signal that younger (< 45 years) and never-smoker individuals were more predispose to dysglycemic effects of air pollution (all P for interactions > 0.03). Our findings suggested that long-term exposure to air pollution increased incident dysglycemia risk, the effect which was mainly attributable to IFG status.

Metabolic effects of dopamine-agonists treatment among patients with prolactinomas.

PURPOSE: To evaluate the effect of cabergoline treatment on metabolic parameters including the Triglyceride-glucose (TyG) index in newly diagnosed patients with prolactinoma. METHODS: 71 consecutive nondiabetic patients with prolactinoma were enrolled. Anthropometric and laboratory tests including TyG index were measured at baseline, 3 and 6 months visits. Treatment with cabergoline at the dose of 0.25 mg twice weekly was started and increased according to prolactin levels and continued for 6 months. RESULTS: At the baseline examination, the mean (SD) age, body mass index (BMI), waist circumference (WC), systolic blood pressure (SBP), and diastolic blood pressure (DBP) of patients were 36.2 (10.5) years, 29.2 (5.0) kg/m2, 98.2 (13.7) cm, 115.3 (13.3) mmHg, and 71.4 (8.1) mmHg, respectively. Forty-one (57.7%) of patients were women and 46 (64.8%) had microadenoma. Cabergoline treatment significantly improved anthropometric and metabolic measures including BMI, WC, fasting plasma glucose, triglycerides, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, uric acid (only among women), TyG index, and hypogonadism. Blood pressure (both systolic and diastolic) levels remained steady except for a significant decrease in DBP after 6 months of treatment only among women. A declining trend in MetS prevalence was found from baseline to a 3-month evaluation in both genders which was statistically significant among men. CONCLUSION: Short-term treatment with cabergoline can significantly improve cardiovascular risk factors except for blood pressure. Moreover, the TyG index as a surrogate marker of insulin resistance decreased significantly after the reduction of prolactin by treatment. Generally, results were similar among both genders.

Does the Prone Position During the Shockwave Lithotripsy of Kidney Stones Improve the Stone-Free Rate? Results from a Randomized Clinical Trial.

OBJECTIVE: This study aimed to evaluate the impact of the skin-to-stone distance in the supine and prone positions on the outcome of shockwave lithotripsy of kidney stones. METHODS: In a prospective randomized clinical trial study, 81 patients that candidates for shockwave lithotripsy (SWL) of kidney stones were randomly divided into two groups to perform SWL in the prone position (40 patients) or conventional supine position (41 patients). Demographic data, stone characteristics, skin-to-stone distances (SSD) in CT, SSD during SWL with an ultrasound probe in prone and supine positions, total shock wave rate, total energy (kilovolt), visual analog scale (VAS), complications (Clavien-Dindo scale system), and SWL success rate evaluated in two intervention and control groups. All statistical analysis was performed by independent T-test, Chi-Square test, Fisher exact test, paired T-test, and SPSS 22.0 software for windows. RESULTS: There were no significant differences between demographic characteristics, SWL sessions, the median number of SWLs, the median SWL time, median total energy, VAS, and complications in the two groups. The SFR was numerically higher in the prone SWL group than in the supine SWL group (80% vs. 73.2%) but was not significantly different (P = 0.468). Also, the inline ultrasound (US) measuring of the SSD in the prone position was significantly different from US SSD measures in the supine position in the two groups (Ps = 0.001 and 0.024). The mean SSD was lower in the US measurement during the SWL process that measured in supine and prone position than the CT measurement (73.5 vs. 101.1), which means the routine SSD measured by CT scan is higher than SSD in the US probe measurement during SWL. CONCLUSION: The prone position SWL modification could be effective in obese patients with a BMI of more than 30 and increase the stone-free rate (P=0.039) with a similar safety profile and comparable VAS score. It seems the SSD measured by the ultrasound is a more accurate dynamic measurement during the SWL and needs to define the SSD according to the SSD calculation by the US probe of the therapy head. SFR was numerically higher in the prone compared with the supine treatment groups.
