Prevalence of depression, anxiety, and stress and associated reasons among Iranian primary healthcare workers: a mixed method study.

BACKGROUND: Different mental disorders may be associated with many work-related factors to which primary health care workers (PHCWs) are exposed. The current research aims to measure the rates of depression, anxiety, and stress among PHCWs, and their associated causes in primary health care (PHC) settings. METHODS: An explanatory sequential mixed methods design was employed in this research from January 2021 to January 2022 in Tabriz, Iran's PHC centers. First, this study followed an online-based cross-sectional survey using a self-reported questionnaire. The Depression, Anxiety and Stress Scale-21 Items (DASS-21) and questions on demographic and work-related characteristics were completed by 303 frontline PHCWs during the quantitative phase. In the qualitative phase, a semi-structured interview was held with 12 PHCWs who had the highest level of depression, anxiety, and stress to identify the reasons and sources of mental health prevalence. Quantitative data were analyzed using descriptive statistics via SPSS-26. A content analysis was performed to analyze qualitative data. RESULTS: The results showed that self-reported stress, anxiety, and depression had a prevalence of 40.3%, 42.9%, and 42.6%, respectively. Symptoms of at least one mental disorder were experienced by 54% of respondents, while 28% had all three. Major sources of stress, anxiety, and depression among PHCWs were working environment conditions, organizational policies, job-related reasons, and interpersonal relations. CONCLUSIONS: The results of current study indicated that PHCWs experienced high levels of depression, anxiety, and stress. The main factors and reasons that contributed to these mental health issues among PHCWs were work environment conditions, organizational policies, job-related reasons and interpersonal relations. Therefore, interventions should be implemented to promote mental health of PHCWs. This can include measures such as psychological screening, supportive care, workload management, flexible scheduling, and access to mental health resources. Additionally, training programs can be implemented to enhance resilience and coping skills among healthcare professionals.

Effects of Posterior Tibial Nerve Stimulation on Fecal Incontinence: An Umbrella Review.

PURPOSE: This study aimed to summarize relevant data from previous systematic reviews (SRs) and conduct comprehensive research on the clinical effects of posterior tibial nerve stimulation (PTNS), via the transcutaneous posterior tibial nerve stimulation (TPTNS) or percutaneous posterior tibial nerve stimulation (PPTNS) method on fecal incontinence (FI). MATERIALS AND METHODS: In adherence to the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines, a systematic search was conducted on PubMed, Embase, Scopus, and Web of Science databases. We included English-language, full-text SRs reporting outcomes for FI following either PPTNS or TPTNS. The quality of included studies was assessed using the Joanna Briggs Institute checklist. In addition, reanalyzing the meta-analyses was conducted using Comprehensive Meta-Analysis (CMA) software version 3.0 to achieve effect sizes and the level of statistical significance was set at p ≤ 0.05. RESULTS: From a total of 835 citations, 14 SRs met our inclusion criteria. Four of these also conducted a meta-analysis. Most SRs reported an overall improvement in different study parameters, including bowel habits and quality of life. However, there were major inconsistencies across the results. The most studied outcome was FI episodes, followed by incontinence score. The summary outcomes showed no statistically significant changes in comparing PTNS with sham or sacral nerve stimulation (SNS) for FI (p > 0.05). However, the results of subgroup analysis based on the type of intervention in the control group revealed that FI episodes were significantly fewer than in the PTNS arm, whereas PTNS led to fewer episodes of FI than did the sham. In terms of incontinence score, the results showed that PTNS compared with sham did not change the incontinence score; however, SNS improved the score significantly in one eligible study for reanalysis when compared with PTNS (p < 0.001). CONCLUSIONS: The findings of the current umbrella review suggest that PTNS can potentially benefit patients with FI. However, this is concluded from studies with a limited population, disregarding the etiology of FI and with limited follow-up duration. Therefore, caution must be taken in contemplating the results.

Effects of posterior tibial nerve stimulation (PTNS) on lower urinary tract dysfunction: An umbrella review.

BACKGROUND: Lower urinary tract dysfunction (LUTD) is a common, troublesome condition that often negatively affects patients' quality of life. Current literature has long been interested in how posterior tibial nerve stimulation (PTNS) can affect this condition. AIM: To extensively and systematically explore how PTNS affects LUTD based on the most recent systematic reviews. METHODS: A systematic search was conducted in PubMed, Scopus, Web of Science, and Embase according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. All the systematic reviews, with or without meta-analysis that assessed the effects of PTNS on LUTD were retrieved. The quality of the included studies was assessed using the Joanna Briggs Institute tool, and analysis was conducted using the Comprehensive Meta-Analysis version 3 tool. RESULTS: From a total of 3077 citations, 20 systematic reviews entered this study, and 13 of them included meta-analysis. The population of studies varied vastly, for instance, some studies included only children or women while other focused on a specific pathology like multiple sclerosis-induced neurogenic LUTD. The majority of included studies reported an overall improvement in LUTD following percutaneous PTNS, although admitting that these results were derived from moderate to low-quality evidence. CONCLUSION: The findings of this thorough umbrella review showed that the positive benefits of PTNS in treating LUTD are currently supported by low-quality evidence, and it is crucial to interpret them with great care.

Efficacy of Tibial Nerve Stimulation in Neurogenic Lower Urinary Tract Dysfunction Among Patients with Multiple Sclerosis: A Systematic Review and Meta-analysis.

OBJECTIVE: This study was performed to systematically review the current literature on the effects of transcutaneous tibial nerve stimulation and percutaneous tibial nerve stimulation on multiple sclerosis-induced neurogenic lower urinary tract dysfunction. MATERIALS AND METHODS: Medical databases including PubMed, Scopus, Embase, and Web of Science were systematically searched from inception to September 2022. Metaanalysis was carried out using the comprehensive meta-analysis tool. RESULTS: Our inclusion criteria were met by 12 studies evaluating the effects of percutaneous tibial nerve stimulation/transcutaneous tibial nerve stimulation on multiple sclerosis-induced neurogenic lower urinary tract dysfunction. Comparing the postintervention results to the baseline showed that the rate of frequency was decreased in both percutaneous tibial nerve stimulation and transcutaneous tibial nerve stimulation groups after intervention. The overall mean change of tibial nerve stimulation on frequency was -2.623 (95% CI: -3.58, -1.66; P < .001, I 2 : 87.04) among 6 eligible studies. The post-void residual was decreased after treatment in both methods of tibial nerve stimulation, with an overall mean difference of -31.13 mL (95% CI: -50.62, -11.63; P=.002, I 2 : 71.81). The other urinary parameters, including urgency (mean difference: -4.69; 95% CI: -7.64, -1.74; P < .001, I 2 : 92.16), maximum cystometric capacity (mean difference: 70.95; 95% CI: 44.69, 97.21; P < .001, I 2 : 89.04), and nocturia (mean difference: -1.41; 95% CI: -2.22, 0.60; P < .001, I 2 : 95.15), were improved after intervention, too. However, the results of subgroup analysis showed no effect of transcutaneous tibial nerve stimulation on urinary incontinence (mean difference: -2.00; 95% CI: -4.06, 0.06; P=.057, I 2 : 95.22) and nocturia (mean difference: -0.39; 95% CI: -1.15, 0.37; P=.315, I 2 : 84.01). In terms of mean voided volume, the evidence was related to only percutaneous tibial nerve stimulation with a mean change of 75.01 mL (95% CI: -39.40, 110.61; P < .001, I 2 : 85.04). CONCLUSION: Although the current literature suggests that tibial nerve electrostimulation might be an effective method for treating neurogenic lower urinary tract dysfunction, the evidence base is poor and derived from small, mostly nonrandomized trials with a high risk of bias and confounding.

Effects of continuous use of Tadalafil on male sexual function after posterior urethroplasty: A clinical trial.

INTRODUCTION: Posterior urethral injuries in men commonly occur following pelvic and perineal trauma. Erectile dysfunction (ED), whether brought on by the severity of the initial trauma or the surgery itself, is one of the complications in these patients. MATERIALS AND METHODS: In this study, we divided candidates of posterior urethroplasty due to traumatic urethral injury into intervention and placebo groups; the former received continuous treatment with tadalafil (10 mg daily), and the latter received a placebo. Other services were provided equally to both groups. Before and after the intervention, both groups completed the International Index of Erectile Function version 5 (IIEF-5) questionnaire, and the findings were analyzed. RESULTS: Forty patients were studied in groups of 20 with a mean age of 43.87 ± 15.70 years. The patient's most common cause of urethral injury was a pelvic fracture. Before the intervention, the mean scores of IIEF for patients in the intervention group and placebo group were 14.85 ± 7.39 and 14.77 ± 6.48, respectively with no statistical significance (p = 0.962) and patients of the groups were similar in terms of the severity of ED. The mean IIEF score in the intervention group was 20.12 ± 4.94 and in the placebo group, it was 18.05 ± 4.88 at the three-month follow-up, with no statistically significant difference (p = 0.063). In both the intervention and placebo groups, the IIEF score was significantly increased by 5.27 ± 4.04 (p < 0.001) and 3.27 ± 2.97 (p < 0.001), respectively. The rate of IIEF increase in the intervention group was higher than in the placebo group during the follow-up at 3-month follow-up with statistical significance. (p = 0.022). CONCLUSION: The findings of this study suggest that tadalafil, in a 3-month treatment course, may improve erectile function in individuals with mild-to-moderate ED, significantly more than placebo. However, more studies, specifically with longer duration of follow-up and larger populations, are necessary for generalizing the current findings.

The optimum cut-off value of contralateral testis size in the prediction of monorchidism in children with nonpalpable testis: A systematic review.

BACKGROUND: Contralateral Testis Hypertrophy (CTH) is a clinical marker that could be used to guide the choice of the main surgical strategy. In patients with a Non-palpable Testis (NPT), the degree of CTH as measured by testicular length or volume has been shown to be able to predict whether the undescended testis will survive. OBJECTIVE: The purpose of this study was to establish the proper cut-off for identifying non-viable testes based on the current literature. DESIGN: We systematically searched several medical databases as well as Google Scholar search engines for references and citations. All the studies that reported CTH as a result of NPT in prepubertal boys were included. Data from the included articles was gathered by two independent reviewers. The checklist developed by the Joanna Briggs Institute (JBI) was used to evaluate the methodological quality of the studies that were included. Due to the incredibly high degree of heterogeneity among the studies, no meta-analysis was done. RESULTS: The current systematic review included 17 studies that assessed the cut-off point to detect non-viable testis. The size and length of the testes were taken into consideration based on our findings. We found that different studies reported various ideal cut-off values for predicting non-viable testes, which can be brought on by various measuring techniques, evaluation ages, and patient groupings. The difference in testis volume was greater than the difference in its length, which can be attributable to the fact that some studies used an orchidometer to measure the testis's length directly or indirectly. CONCLUSION: According to the results of our study, it seems that defining a cut point for diagnosis of CTH based on the size of the testis, cannot demonstrate the absence of a non-palpable testis.

Management of urolithiasis in pregnancy: A systematic review and meta-analysis.

PURPOSE: Management of nephrolithiasis is unique in pregnancy and requires multidisciplinary care. To identify the effectiveness or safety of temporary drainage or definitive treatment methods to manage urolithiasis in pregnancy. METHODS: The search strategy aimed to find both published and unpublished studies was conducted in August 2021. Studies published in any language on any date were considered for inclusion. RESULTS: Of a total of 3349 publications, 36 studies were included in our qualitative evaluation and 32 studies in the quantitative synthesis. The commonly reported method was stent insertion (n = 29 studies), pneumatic (n = 12), laser (n = 9) lithotripsy, and stone removal using any devices (basket, grasper, or forceps) (n = 11). In seven studies, the authors reported the outcomes of conservative management, and the results showed that the stone-free rate is 54%, and symptom relief occurred in 62% of women. Seven eligible studies reported that 79.9% of urolithiasis were expulsed through stent insertion, while this rate was 94.6% among percutaneous nephrostomy use in two included studies, 88.5% for pneumatic lithotripsy (n = 7 studies), and 76.4% for laser lithotripsy (n = 4 studies), or 95.4% for stone removal method. In addition, adverse events were reported in less than 10% of pregnant women. CONCLUSIONS: The results showed that stent, pneumatic or laser lithotripsy, and ureteroscopic stone removal were the commonest used methods in the included studies. They can be effective and safe treatment approaches without major maternal or neonatal complications, and could be introduced as an effective and safe therapeutic method for urolithiasis during pregnancy. However, most of the included studies had moderate quality according to critical appraisal checklists. Further prospective studies are needed to reach a conclusion.

Efficacy of polyarginine peptides in the treatment of stroke: A systematic review and meta-analysis.

BACKGROUND: Disparities exist regarding an efficient treatment for stroke. Polyarginines have shown promising neuroprotective properties based on available published studies. Thus, the present study aims to systemically review and analyze existing evidence regarding polyarginine's administration efficacy in animal stroke models. METHOD: Medline, Scopus, Embase, and Web of Science were systematically searched, in addition to manual search. Inclusion criteria were administrating polyarginine peptides in stroke animal models. Exclusion criteria were previous polyarginine administration, lacking a control group, review articles, and case reports. Data were collected and analyzed using STATA 17.0; a pooled standardized mean difference (SMD) with a 95% confidence interval (CI), meta-regression, and subgroup analyses were presented. Risk of bias, publication bias, and level of evidence were assessed using SYRCLE's tool, Egger's analysis, and Grading of Recommendations Assessment, Development and Evaluation framework, respectively. RESULTS: From the 468 searched articles, 11 articles were included. Analyses showed that R18 significantly decreases infarct size (SMD = -0.65; 95% CI: -1.01, -0.29) and brain edema (SMD = -1.90; 95% CI: -3.28, -0.51) and improves neurological outcome (SMD = 0.67; 95% CI: 0.44, 0.91) and functional status (SMD = 0.55; 95% CI: 0.26, 0.85) in stroke animal models. Moreover, R18D significantly decreases infarct size (SMD = -0.75; 95% CI: -1.17, -0.33) and improves neurological outcome (SMD = 0.46; 95% CI: 0.06, 0.86) and functional status (SMD = 0.35; 95% CI: 0.16, 0.54) in stroke models. CONCLUSION: Moderate level of evidence demonstrated that both R18 and R18D administration can significantly improve stroke outcomes in animal stroke models. However, considering the limitations, further pre-clinical and clinical studies are warranted to substantiate the neuroprotective efficacy of polyarginines for stroke.

Chronological perspective of substitute materials used for the surgical treatment of Peyronie's disease: A scoping review of literature.

This comprehensive scoping review aimed to identify all up-to-date original publications relating to substitute materials used for the surgical treatment of Peyronie's disease (PD), and characterize what material in which chronological trends were published in the current literature. Using the PCC framework (P: population, C: concept, and C: context), a search strategy was developed and used in four electronic databases, in addition to the Google scholar. All current published, in-press, and pre-print manuscripts with available English full-text were included. Eligible studies were required to be original research articles of any study design, reporting the usage of grafts on surgical treatment of PD. Included studies were reported in a narrative synthesis format. A total of 3379 articles were identified via an electronic search of databases and a total of 171 articles entered this scoping review. Most studies originated from Europe (n = 72) and North America (n = 66). Reports from the other continents increase in number in the 21st century. Highest number of the published papers was seen in 2001 to 2005 pentad. Autologous grafts (53.5%). Allografts (22.7%) and xenografts (15.7%) were the most frequently reported materials. Time flow of the used material and the alterations in trends for them is quite considerable. A global perspective of relevant publications on substitute materials in the surgical management of PD is presented in this review. The information in this summary may assist in establishing future research priorities in this area.

Effects of saffron (Crocus sativus L.) on anthropometric and cardiometabolic indices in overweight and obese patients: A systematic review and meta-analysis of randomized controlled trials.

The worldwide prevalence of obesity is approximately tripled between 1975 and 2016 according to World Health Organization; therefore, obesity is now considered a global pandemic that needs academic and clinical focus. In search of antiobesity agents, Crocus sativus, known widely as saffron, has been praised for its beneficial effects. Several randomized controlled trials (RCTs) have been conducted to investigate the weight lowering effect of saffron. Following PRISMA guidelines, several medical databases were comprehensively searched for RCTs with a population consisting of obese individuals. A random-effects meta-analysis was used to pool estimates across studies, and standardized mean difference (SMD) was used to synthesize quantitative results. Twenty-five RCTs met the inclusion criteria. Meta-analysis showed a nonsignificant decrease for weight (-0.32 kg; CI: -3.15, 2.51; p = 0.82), BMI (-0.06 kg/m2 ;CI:-1.04,0.93; p = .91), waist circumference (-1.23 cm; CI: -4.14, 1.68; p = .41), and hip circumference (-0.38 cm; CI: -5.99, 5.23; p = .89) and a significant decrease of waist-to-hip ratio (SMD = -0.41; CI: -0.73, -0.09; p = .01; I2  = 0%). The mean difference in fasting blood sugar showed a significant reduction in patients with metabolic syndrome (SMD = -0.30; 95% CI: -0.63, 0.03; p = .07; I2  = 0.37%) but a nonsignificant change in the HbA1C level (WMD = 0.05; 95% CI: 0.32, 0.41; p = .79). Despite bearing several limitations, mainly as a result of heterogeneity among included studies, the available evidence indicates saffron supplementation shows promising effects on some cardiometabolic factors among overweight to obese patients; however, further investigations and high-quality evidence are required for more generalizable and comprehensive results.

Effects of probiotic supplementation on cognitive function in elderly: A systematic review and Meta-analysis.

OBJECTIVES: Probiotic supplementation has been linked to changes in cognitive function via the gut-brain axis (GBA). However, the current literature lacks a comprehensive review regarding this matter in the elderly population. METHOD: Electronic databases including Medline (PubMed), Scopus, Embase, Web of Science, and Google Scholar were comprehensively searched for identifying studies that assessed the effects of probiotics on the cognitive function of the elderly published until July 2020. Articles were critically reviewed and if met the inclusion criteria, entered the study. RESULTS: Among a total of 1374 studies, 10 were eligible for meta-analysis. No significant alteration was found in the cognition of the elderly (SMD=-0.04; 95% CI [- 1.07,0.98]; P = 0.93). There was a nonsignificant increase in the level of brain-derived neurotrophic factor (SMD = 0.58; 95% CI [-1.40,2.56]; P = 0.56) and a nonsignificant reduction in malondialdehyde levels (SMD=-0.44; 95% CI [-1.07,0.19]; P = 0.17). Levels of total antioxidant capacity (SMD = 39.93; 95% CI [2.92,76.95]; P = 0.03) and total glutathione (SMD = 61.51; 95% CI [12.39,110.62]; P = 0.01) significantly increased. A significant reduction was also noted in total cholesterol levels (SMD=-4.23; 95% CI [-8.32, -0.14]; P = 0.04). CONCLUSION: Our study did not support the hypothesis of the positive effect of probiotics on cognitive function in the elderly population; which might be due to the heterogeneity across the studies.

Neurological manifestations of COVID-19 infection: an umbrella review.

BACKGROUND: Neurological involvements of COVID-19 are one of the most reported manifestations of this infection. This study aims to systematically review the previous systematic reviews which addressed the neurological manifestations of the COVID-19 infection. METHODS: Following the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines, a comprehensive search was conducted in PubMed, Embase, Scopus, Web of Science databases and Google Scholar from December 2019 to December 2020. Articles were critically screened by two independent reviewers and if met the inclusion criteria, entered the study. Assessment of methodological quality was conducted by Assessment of Multiple Systematic Reviews-2 (AMSTAR-2) tool. Statistical analysis was not applicable. From a total of 1302 studies, 308 studies were removed due to their irrelevant title and abstract. After screening the full texts, a total of 66 found to be eligible. Twenty-one studies reported general manifestations of the COVID-19, 13 studies reported cerebrovascular events, 19 olfactory and oral dysfunctions, 5 systematic reviews on Guillen-Barré syndrome (GBS) and 8 articles on the sporadic manifestations like ocular signs and symptoms. The majority of the studies were classified as critically low or low in terms of quality. CONCLUSION: Despite great heterogeneity in the current literature, neurological involvements are an important extra-pulmonary aspect of the COVID-19; most commonly in the form of general manifestations like headache and olfactory disturbances. Long-term effects of this virus on the nervous system must be a research priority for future references. SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1186/s41983-021-00366-5.

Percutaneous Drainage with Injection of Ethanol as the Sclerosing Agent for Treatment of Simple Kidney Cysts: A New Modification.

Introduction: The simple kidney cyst is the most common type of benign kidney tumor in adults and it is usually asymptomatic. Symptomatic cysts are treated with percutaneous aspiration with or without sclerosing agent injection, laparoscopic decortication, or open surgery in rare cases. Considering the probable complications of anesthesia in open surgery and laparoscopic methods, we used an innovative method of percutaneous aspiration, insertion of a single J draining catheter for 24 hours, and injection of sclerosing agents, leaving the agent inside the cyst, while the catheter was removed immediately. Long-term results of this method were evaluated using sonography. Materials and Methods: Twenty-eight patients with symptomatic kidney cysts underwent the process of insertion of the percutaneous catheter and aspiration of its contents in two steps and a one-time injection of 95% ethanol. After the first aspiration, patients stayed admitted for 24 hours. Then, the second aspiration was performed and the total fluid volume was measured. Patients were then followed for a mean follow-up period of 14 months. The procedure was considered effective with no signs of relapse (consistent with reduced size of cysts) in a sonographic evaluation of long-term results. Results: Among all the patients, 23 (82.14%) showed positive results in the sonographic evaluation after 14 months. Death occurred in one patient (3.6%), not attributable to the procedure, and recurrence was observed in five patients (17.9%). Conclusions: Our study showed that this method is safe, effective, and minimally invasive in treating simple kidney cysts and can be a proper substitute for the other current methods.

Ramadan Fasting and Kidney Stones: A Systematic Review.

PURPOSE: Ramadan fasting in Muslims may contain several hours of abstaining from food and drinking in any kind. This can potentially increase the risk of urinary stone disease. Current literature on possible effects of Ramadan fasting on urolithiasis is rather limited. Having the gap in scientific background, we decided to evaluate the available comparative information in this systematic review. MATERIALS AND METHODS: We included all studies comparing fasting and non-fasting conditions, studies evaluating stone formation and clinical manifestations of kidney stone disease. All the English studies published from January 1980 to the end of 2019 were included. The exclusion criteria were as followed: fasting out of Ramadan, non-comparative studies, animal studies, patients with bladder stones, and studies evaluating conditions that are only indirectly related to the stone formation or clinical manifestations of it. Applying the Joanna Briggs Institute (JBI) methodology for systematic review showed the quality of included studies was not high. RESULTS: Only five studies remained after exclusion. Meta-analysis was not applicable due to the diversity in methods and evaluated population. CONCLUSION: Main trend of the included studies is toward showing no difference between fasting and non-fasting conditions in terms of renal stone formation. However, generalization of the findings to greater populations should be applied carefully considering the heterogeneity of results and quality of studies.

Isolation and Identification of Secondary Metabolites from the Aerial Parts of Stachys lavandulifolia Vahl.

Stachys lavandulifolia Vahl is an herbaceous wild plant native to Iran which is traditionally used in Iranian folk medicine as a mild sedative tea for reducing anxiety and for treatment of gastrointestinal disorders. Our previous study on ethyl acetate extract of S. lavandulifolia proved anti-anxiolytic activity and so the present study was designed to determine chemical components of this biologically active fraction. The extract was prepared using maceration method. Column chromatography and medium pressure liquid chromatography (MPLC) was used respectively to separate the fractions. Finally, some evaluated fractions were used for high pressure liquid (HPLC) and peak shaving recycle technique to achieve more purification. Separated compounds were determined using NMR analysis and mass spectroscopy. Six compounds have been isolated from ethylacetate extract of aerial parts of S. lavandulifolia including four flavonoids (apigenin, kumatakenin, penduletin and 4', 7-dihyroxy- 3, 5, 6-trimethoxy flavon), a labdan diterpenoid (labda-13-en-8, 15-diol), and an iridoid.
