RESUMEN
Background & Objective: The most frequent type of cancer found in the endocrine system is thyroid carcinoma. Among well-differentiated thyroid malignancies, the most commonly occurring type is identified as papillary thyroid carcinoma (PTC), which makes up 70-90% of the cases. A subtype of PTC is papillary thyroid microcarcinoma (PTMC), which includes tumors smaller than 10 mm in diameter. Due to the advancements in diagnostic techniques, the incidence of this type of cancer is on the rise. In this study, we aimed to analyze the factors worsening the PTMC prognosis. Methods: In the first step, we searched various databases for the factors affecting this tumor. The relevant articles were collected and different outcomes of this tumor and its associated factors which were studied in more than one article, were classified. Finally, we conducted a meta-analysis of these outcomes and their related factors. Results: In the meta-analysis, a significantly association was found between the following factors: recurrence with gender (P<0.001) lymph node metastasis (LNM) (P= 0.003), and extrathyroidal invasion (P<0.001); lymph node metastasis with extrathyroidal invasion (P<0.001), and multifocality (P<0.001); central lymph node metastasis (CLNM) with gender (P=0.001), tumor size (P<0.001), extracapsular invasion (P<0.001), lateral cervical lymph node metastasis (P<0.001), and extrathyroidal invasion (P<0.001); lymph node metastasis resulted in poor outcomes (P<0.001); and finally tumor size with BRAFV600E mutation (P<0.001). Conclusion: In conclusion, it is essential to note that greater awareness and understanding of this tumor characteristics and special and separate attention to PTMC can significantly improve the society overall health.
RESUMEN
BACKGROUND: The prevalence of dyslipidemia in patients with type 2 diabetes (T2D) has been reported to be relatively high. The current study aimed to investigate the trend of serum lipid levels and the prevalence of dyslipidemia in patients with T2D. METHODS: Data were extracted from a cohort of patients with T2D who had regular follow-ups every year for three years. TG, TC, LDL-C, HDL-C, and non-HDL-C were analyzed. The atherogenic index of plasma (AIP) was calculated using log (TG/HDL-C). RESULTS: A total of 747 patients with T2D were included in this study, consisting of 469 (62.8%) women and 278 (37.2%) men. There was a significant downward trend in mean TG, TC, LDL-C, non-HDL-C, and AIP levels. The trend of mean HDL-C levels showed no significant change. The prevalence of high TG, high TC, high LDL-C, and high non-HDL-C significantly decreased from the first to the last visit. There was no significant change in the trend of prevalence of low HDL-C. The prevalence of high AIP significantly decreased in women and showed no significant changes in men. CONCLUSIONS: A decreasing trend was observed in the mean levels and prevalence of TG, TC, LDL-C, non-HDL-C, and AIP. HDL-C did not change significantly. The success rate in achieving a complete normal lipid profile during follow-up years was not promising and continues to be challenging.

BACKGROUND: The etiology of LARS has not been elaborated on clearly. Studies have reported neoadjuvant therapy, low-lying rectal cancers, adjuvant therapy and anastomotic leakage as risk factors for the development of LARS. Anastomotic level has also been proposed as a possible risk factor; However, there have been conflicting results. This study aims to evaluate the role of the level of anastomosis as a potential risk factor for the development of LARS. METHOD: A systematic literature search was conducted on Pubmed, Scopus, Embase, and Web of Science databases using Mesh terms and non-Mesh terms from 2012 to 2023. Original English studies conducted on rectal cancer patients reporting of anastomotic level and LARS status were included in this study. Eligible studies were assessed regarding quality control with Joanna-Briggs Institute (JBI) questionnaires. RESULTS: A total of 396 articles were found using the research queries, and after applying selection criteria 4 articles were selected. A sample population of 808 patients were included in this study with a mean age of 61.51 years with male patients consisting 59.28% of the cases. The Mean assessment time was 15.6 months which revealed a mean prevalence of 48.89% for LAR syndrome. Regression analysis revealed significantly increased risk of LAR syndrome development due to low anastomosis level in all 4 studies with odds ratios of 5.336 (95% CI:3.197-8.907), 3.76 (95% CI: 1.34-10.61), 1.145 (95% CI: 1.141-2.149) and 2.11 (95% CI: 1.05-4.27) for low anastomoses and 4.34 (95% CI: 1.05-18.04) for ultralow anastomoses. CONCLUSIONS: LARS is a long-term complication following surgery, leading to reduced quality of life. Low anastomosis level has been reported as a possible risk factor. All of the studies in this systematic review were associated with an increased risk of LARS development among patients with low anastomosis.

Hypertension (HTN) management continues to be a concern due to challenges with behavioral risk factors. Patient education to modify unhealthy behaviors appears to be effective in managing HTN. Therefore, this meta-analysis aimed to determine whether individualized face-to-face education and counseling have a beneficial effect on systolic and diastolic blood pressure (SBP and DBP) in hypertensive patients. Studies were extracted from PubMed, Scopus, Cochrane Library, and Web of Science databases. Nine studies, comprising 2627 participants, were included. Random effects models were used to pool estimates of mean differences (MDs) with 95% confidence intervals (CIs) in SBP and DBP between the intervention and usual care groups. SBP and DBP were significantly reduced at the 6-month (MD = -4.38 mmHg, 95% CI: -6.95 to -1.81; MD = -2.09 mmHg, 95% CI: -3.69 to -0.50, respectively) and 12-month time points (MD = -2.48 mmHg, 95% CI: -3.96 to -1.01; MD = -1.71 mmHg, 95% CI: -2.88 to -0.55, respectively) with intervention. At the 24-month time point, there was a significant change in SBP (MD = -2.13 mmHg, 95% CI: -3.94 to -0.32) with intervention compared with the usual care group. This study showed that individualized face-to-face education and counseling add significant benefits to usual care for lowering blood pressure in hypertensive patients. Graphical Abstract.

Thirty years ago, patients with low ejection fraction (EF) have often been excluded from rehabilitation programs due to concern about possibility of sudden death or other adverse cardiovascular events during exercise sessions. Recent studies have highlighted the fact that cardiac rehabilitation could improve exercise capacity, cardiac function, and health-related quality of life in congestive heart failure patients. This encouraged us to write a review article and update our latest knowledge about the outcome of rehabilitation program in patients with severely depressed cardiac function. We were particularly interested in effect of cardiac rehabilitation on exercise capacity, quality of life, vascular effects, neuro-hormonal changes, and mortality. We also conducted a mini-systematic review and meta-analysis on randomized controlled trials comparing exercise training with usual care in patients with severely reduced left ventricular ejection fraction, for the mortality subsection to obtain precise estimates of overall treatment benefit on mortality. It is our privilege to submit our manuscript for possible publication in your prestigious journal.

AIMS: To investigate the relationship between the triglyceride-glucose (TyG) index, a novel surrogate index of insulin resistance (IR), and metabolic syndrome (MetS) in a systematic review and meta-analysis. DATA SYNTHESIS: Studies that report the TyG index in adult subjects with and without MetS were included. Thirteen observational articles were included in this study, with a total of 49,325 participants. Two different categories of meta-analyses were performed. First, the means of the TyG index were compared in participants with and without MetS. The pooled mean difference (MD) of the TyG index between groups was 0.83 units (CI 95: 0.74-0.92, I2 = 98, P-value < 0.001), and the subgroup analyses showed MD significantly differed based on the MetS diagnostic criteria. The pooled MD were 0.80 units (CI 95: 0.70-0.91, I2 = %88, P-value < 0.001) and 0.82 units (CI 95: 0.79-0.86, I2 = %0, P-value > 0.767) for studies reported data for males and females individual, respectively. Second bivariate diagnostic test accuracy (DTA) meta-analysis was performed and determined that the TyG index's pooled sensitivity and specificity for screening of MetS were 80% (CI95: 75%-84%, I2 = 87%, P-value < 0.001) and 81% (CI95: 77%-84%, I2 = 90.45%, P-value < 0.001), respectively. Summary receiver-operating characteristics (sROC) curves were also plotted with the area under the sROC curve of 0.87 (CI 95: 0.84-0.90). CONCLUSIONS: The TyG index is a sensitive and specific index for MetS and may be valuable for MetS screening. PROSPERO: CRD42022316209.

BACKGROUND: There is debate on the necessity of booster doses of COVID-19 vaccination, especially in countries with limited resources. METHODS: This cross-sectional study was conducted in a referral laboratory in Tehran, Iran. The level of COVID-19 antibodies was measured and compared between individuals regarding the number of COVID-19 vaccine shots. RESULTS: In this study, 176 individuals with a mean age of 36.3 (±11.7) years participated. A total of 112 individuals received two doses of the COVID-19 vaccine, and 64 individuals received three doses. Level of all antibodies was higher in those who received three doses than in those who received two doses of the COVID-19 vaccine. Considering the SARS-CoV-2 Spike IgG, the difference was not statistically significant but for the SARS-CoV-2 RBD IgG and SARS-CoV-2 NAB the difference was statistically significant. Regarding to the background variables, receiving influenza vaccine in the past year, history of autoimmune diseases and past medical history of chicken pox showed a significant association with the number of vaccine doses received. Their effects on the outcome variables assessed with multivariate logistic regression analysis. CONCLUSION: The results of our study show that a booster dose of the COVID-19 vaccine enhances the antibody response.
RESUMEN
BACKGROUND: Considering the importance of intention to receive COVID-19 vaccine among healthcare workers and its role in maintaining their health and inhibiting the epidemic spread of Covid-19, the present study was done to identify the changes in intention to receive COVID-19 vaccine rate in two different time points and it's determinants based on the dimensions of the health belief model among healthcare workers in Iran. METHODS: Two cross-sectional surveys performed to investigate COVID-19 vaccination intent and associated factors based on the health belief model. The first conducted on 1244 participants from August 18 to 23, 2020, and the second on 1514 participants from February 5 to April 29, 2021, both using a questionnaire of intent to accept COVID-19 vaccination. The questionnaire distribution platform in both surveys was similarly, WhatsApp and Telegram social and working virtual groups of HCWs. Data were analyzed with SPSS-16 software for descriptive and analytical statistics. RESULTS: In the first survey, 58.4% (95% CI: 0.55-0.61%) of healthcare workers intended to receive the COVID-19 vaccine, the rate dropped to 45.7% (95% CI: 0.43-0.48%) in the second survey (P < 0.001). The regression analysis indicated six factors that were significantly associated with higher intention to receive COVID-19 vaccine: being a female (OR = 1.84, 95% CI (1.11-3.03)), history of Covid-19 infection (OR = 1.54, 95% CI (1.09-2.18), perceptions of Covid-19 disease (OR = 1.13, 95% CI (1.01-1.28)), perceived benefits of COVID-19 vaccine (OR = 1.34, 95% CI (1.22-1.47)), prosocial norms for COVID-19 vaccination (OR = 1.25, 95% CI (1.21-1.29)), and COVID-19 vaccine safety/cost concerns (OR = 1.25, 95% CI (1.17-1.33)). CONCLUSIONS: Present study showed an undesirable rate of intention to receive COVID-19 vaccine among healthcare workers, especially decreasing over the time, emphasize the need of interventions to promote healthcare workers' intention to receive the vaccine and reduce the spread of COVID-19 disease.

OBJECTIVE: To investigate the effects of pentoxifylline (PTX) in combination with losartan compared to the high dose of losartan alone on serum markers of diabetic nephropathy such as HSP70, copeptin, CRP, and TNFα in patients with type 2 diabetes and nephropathy. METHODS: A single-center, randomized, double-blind, open-label clinical trial was conducted. Sixty-two patients were eligible and allocated to "PTX + losartan" and "high-dose losartan" arms of the trial using software for random number generation. The first arm received 400 mg PTX two times a day (BD) plus 50 mg losartan daily, while the second arm received 50 mg losartan two times a day (BD) for 12 weeks. Comparison of the biomarkers' levels before and after treatment was done using paired sample t test variance. ANCOVA was applied to evaluate the comparative efficacy of the two interventions. The effect size was calculated and reported for each biomarker. RESULTS: Urine albumin excretion (UAE), hs-CRP, and HbA1c significantly decreased in both trial arms compared to the baseline measures. Copeptin and TNFα showed significant differences (after vs before) only in the losartan group (p = 0.017 and p = 0.043, respectively). The losartan arm was more successful in reducing TNFα, copeptin, HSP70, systolic blood pressure (SBP), and diastolic blood pressure (DBP) values (p = 0.045, effect size = 7.3%; p = 0.018, effect size 10.1%; p = 0.046, effect size 4.7%, p = 0.001, effect size 23%; p = 0.012, effect size 10.2%, respectively) and the PTX arm was associated with a superior reduction of UAE and hs-CRP levels (p = 0.018, effect size 9.1%; p = 0.028, effect size 9.2%, respectively). CONCLUSION: Add-on PTX to losartan may have more effective anti-inflammatory and anti-albuminuric roles and therefore may be more applicable in the management of diabetic nephropathy compared with high-dose losartan alone.

RESUMEN
Coronary heart disease (CHD) is one of the major causes of mortality and morbidity in patients with type 2 diabetes mellitus. In this study, we aimed to assess the association between visit-to-visit variability of fasting blood sugar (FBS), HbA1c, blood sugar 2 h post-prandial (BS2hpp), lipid indices, creatinine, systolic and diastolic blood pressure (SBP, DBP) and incident CHD in patients with type 2 diabetes during a median follow-up of ten years. The current case-cohort study consisted of 1500 individuals with type 2 diabetes, followed up for the occurrence of CHD from 2002 to 2019. The patients had at least four annual follow-ups during which glycemic and lipid profile were measured. Co-efficient of variance (CV) for each parameter was calculated by 10-21 measurements. Cox regression analysis was performed to assess the association between CV of glycemic indices, lipid profile, blood pressure, creatinine, weight and incident CHD during the follow-up period. Hazard ratios (HR) were adjusted for the confounding variables. Glycemic indices variability (i.e., CV-HbA1c, CV-FBS, and CV-BS2hpp), were significantly higher in the group with incident CHD (P=0.034, P=0.042, and P=0.044, respectively). Hazard ratios were 1.42 (95 % CI=1.13-2.09) for CV-HbA1c, 1.37 (95 % CI=1.02-2.10) for CV-FBS, and 1.16 (95 % CI=1.01-1.63) for CV-BS2hpp (P=0.012, P=0.046, P=0.038, respectively). Creatinine was significantly higher in the group with incident CHD (P=0.036) and it was significantly associated with higher incidence of CHD (HR=1.14, 95 % CI=1.02-2.17, P=0.048). Visit to visit variability of glycemic indices of the patients with type 2 diabetes is associated with incident CHD independent of their baseline and mean values.
RESUMEN
BACKGROUND: Theoretically, smoking status should be associated with metabolic syndrome. This relationship has not been studied in Iranian population so far. This study aimed to explore the association among cigarette smoking, metabolic syndrome (MetS) and its domains in a nationally representative sample of Iranians aged 25-64. METHODS: Information of participants regarding demographic data and smoking habits gathered through WHO STEPS questionnaires in the frame of fourth national surveillance of the risk factors of non-communicable diseases in 2011 across the country. The fasting plasma glucose, triglyceride level, high-density lipoprotein cholesterol (HDL-C) level, blood pressure, and anthropometric indices in each patient were measured. Data of 4000 subjects were analyzed with complex sample survey method. The prevalence of metabolic syndrome was assessed according to two definitions: International Diabetes Federation (IDF) and Iranian definition. RESULTS: Herein, 38.4% of smoker participants and 36.6% of non-smokers met the IDF criteria for MetS (P=0.67). Similarly, 31.1% of smokers and 34.1% of non-smokers had MetS according to Iranian-IDF (P=0.427). Only in univariate analysis, using IDF criteria female smokers had lower prevalence of MetS than non-smokers (13.9% vs. 36.5%, P=0.01). Multivariate analysis determined the following odds ratios for the association of smoking with MetS defined by IDF and Iranian-IDF criteria, respectively: OR= 0.89 (0.53-1.47), P=0.638 and OR= 0.97 (0.59-1.58), P=0.901. CONCLUSION: There was no significant association between smoking and MetS overall and among men. However, smoking was associated with lower prevalence of MetS among women.
RESUMEN
This is a meta-analysis of randomized controlled trials (RCTs) investigating the effects of oral vitamin D supplementation on serum fibroblast growth factor-23 (FGF23) concentrations in patients with chronic kidney disease (CKD). Manuscripts were extracted from PubMed/MEDLINE, Scopus, and ISI Web of Science through February 2020. Subgroup analyses, sensitivity analysis, and meta-regression assessments were performed. A total of eight clinical trials with nine treatment arms were included in the final analysis. The pooled results showed no significant changes in circulating FGF23 following vitamin D supplementation compared to the control group (Standardized mean difference (SMD): 0.24; 95% confidence intervals (CIs): -0.03 to 0.50, p > 0.05). Subgroup analyses found that studies which had participants with a body mass index (BMI) higher than 25 kg/m2 , with an intervention duration shorter than 15 weeks, using phosphate binder medications, and trials that were on both patients with CKD undergoing hemodialysis and patients without hemodialysis treatment produced significant increases in FGF23 when concentration compared with the control group. This meta-analysis provides evidence that vitamin D supplementation does not have a significant effect on plasma FGF23 levels. However, further high-quality trials are required to identify the influence of oral vitamin D supplementation on FGF23 levels in patients with CKD.

Although little is known regarding the mechanisms behind the onset of breast cancer (BC) through reproductive risk factors, new researches have highlighted some early tumor-related methylation footmarks in the breast tissue of apparently clinically healthy women as their potential epigenetic mechanism. Previous evidence supports that the estrogen receptor beta (ER-ß), whose anti-cancer roles had already been revealed in BC, is downregulated in the breasts of healthy nulliparous women. Nevertheless, data on such a link about its methylation alterations have not been reported. The goal of current study was to determine possible methylation alterations at CpG island promoter of the ER-ß gene, including promoter 0 N and exon 0 N, in relation to aspects of reproductive history in the healthy breasts. The DNA was extracted from the breasts of 120 subjects undergoing cosmetic mammoplasty. Thereafter, the methylation levels of targeted regions in ER-ß gene were determined by using MeDIP-qPCR assay. The results revealed that ER-ß exon 0 N had no methylation in 84.2 % of the women, whereas the rest, comprising 2.5 % and 13.3 % of the samples, showed a lower and higher of its methylation, respectively. Interestingly, nulliparous women were found to have an elevated methylation level of the ER-ß exon 0 N than parous women (P = 0.036). Moreover, we observed a high methylation of the ER-ß exon 0 N in the breasts of non-breastfeeding women compared to breastfeeding subgroup (P = 0.048). Likewise, the non-breastfeeding subgroup showed exon 0N high methylation in comparison to women with breastfeeding >24 months (P = 0.023). Finally, although we found that 6.67 % of the samples had a high methylation level at the promoter 0N, no any relationship was found between its methylation and reproductive history. These results may provide key clues to revealing the epigenetic mechanism through which the nulliparity and lack of breastfeeding influencing the risk factor of BC as well as introducing the potential new early prediction and prevention strategies. Although further investigations need to be done in order to gain a better understanding the roles of these epigenetic signatures.

COVID-19 vaccines are supposed to be critical measure for ending the pandemic. Governments had to decide on the type of vaccine to provide for their population. In this decision-making process, cost-effectiveness analysis is considered a helpful tool. This study is a cost-effectiveness analysis utilized to calculate the incremental cost per averted disability-adjusted life year (DALY) by vaccination compared to no vaccination for different COVID-19 vaccines. The incremental cost-effectiveness ratio (ICER) for a vaccination with COVID-19 vaccines was estimated at 6.2 to 121.2 USD to avert one DALY and 566.8 to 10,957.7 USD per one death. The lowest and highest ICERs belong to Ad26.COV2.S and CoronaVac, respectively. Considering the scenario of Iran, vaccines that are recommended include ad26.cov2.s, chadox1-S, rAd26-S + rAd5-S, and BNT162b2 in the order of recommendation.
RESUMEN
PURPOSE: To identify influence of different values of age and abnormal bowel length in HD patients selected for single stage TERPT which affects the technique of surgery. METHODS: This observational study was carried out for over 2.5â¯years. All children younger than 14â¯years old with clinical suspicion for HD, typical transitional zone (TZ) on contrast enema (CE) distal to splenic flexure, preoperative diagnosis approved by full thickness biopsy, no previous surgical history and no urgency were included. The distance between the anus and TZ was considered as aganglionic length on CE. Biopsy was taken from distal to proximal of resected bowel to reach circumferentially normal innervated bowel. Paired sample Student's t-test, Pearson correlation test, receiver operating characteristic (ROC) analysis were performed. RESULTS: Forty-eight patients were enrolled in this study. Measured mean for aganglionic bowel length on CE and pathology were 33.5⯱â¯17.1â¯cm and 56.8⯱â¯33.5â¯cm, respectively (p < 0.01). Correlation coefficient (R) and coefficient of determination (R2) were 0.632 and 40%, respectively (p < 0.01). The difference between radiologic and pathologic measurements in females was higher than males (mean: 29.3 vs 21.9â¯cm) but was not statistically significant (pâ¯=â¯0.75). There was statistically significant difference between CE and pathologic results in the infants younger than 10â¯months (p = .004). Abnormal bowel length equal to 52â¯cm predicted requirement of laparoscopy assistance/laparotomy with 75% sensitivity and 85% specificity. CONCLUSION: Our investigation showed it is safe to attempt for single stage TERPT when aganglionic length on CE is less than 52â¯cm and the child with HD is older than 10â¯months. Chance of requiring additional laparotomy or laparoscopy assistance is low in these patients. TYPE OF STUDY: Study of diagnostic test. LEVEL OF EVIDENCE: Level II.

AIMS: To investigate the associations between Lp(a), Apo A1, Apo B, and Apo B/Apo A1 ratio with micro- and macrovascular complications of diabetes. METHODS AND RESULTS: In this case-cohort study, 1057 patients with type 2 diabetes (T2DM) were followed in the diabetes clinic of Vali-Asr Hospital from 2014 to 2019. The association between serum Lp (a) and apolipoproteins with cardiovascular disease (CVD), neuropathy, and nephropathy were assessed by using binary regression analysis. The ROC curve analysis was used to evaluate the predictive properties of proteins. Youden index was used to calculate cutoff values. Among patients with T2DM, 242, 231, and 91 patients developed CVD, neuropathy, and nephropathy, respectively. The serum Lp (a) level was positively correlated with the development of all three. (P-values = 0.022, 0.042, and 0.038, respectively). The Apo A1 level was negatively correlated with nephropathy. Among the biomarkers, Lp(a) had the highest AUC for prediction of CVD, neuropathy, and nephropathy. Calculated cutoff values of Lp(a), and Apo A1 levels were higher than the standard cutoff values. CONCLUSION: Serum level of Lp(a) is a predictor for CVD, neuropathy, and nephropathy. Based on the calculated cutoff values in patients with T2DM, we should consider diabetic complications at higher levels of Lp(a).

OBJECTIVES: Our aim in this study was to assess the relationship between serum lipoprotein(a) [Lp(a)] and apolipoproteins and the risk of developing diabetic retinopathy (DR). METHODS: One thousand fifty-seven patients with type 2 diabetes were divided into 2 main groups and followed for 5 years: 637 patients without DR and 420 patients with DR. A group of patients with DR were then divided into 2 subgroups: 162 patients with nonproliferative DR (NPDR) and 163 patients with proliferative DR (PDR). The association between serum Lp(a) and apolipoproteins with NPDR and PDR was assessed using univariate and multivariate regression analyses. Receiver-operating characteristic curve analysis was performed based on the new cutoff values. RESULTS: There was a positive relationship between Lp(a) and the presence of DR as well as a negative correlation between ApoA and DR (p<0.001 and p=0.03, respectively). We also found a positive association between ApoB and the severity of DR (p=0.008). ApoA1 had an area under the curve of 55.0% for the prediction of DR. The calculated cutoff values of ApoB/ApoA1 ratio (0.58 g/L) and ApoB (77.5 g/L) in detection of DR were lower than their standard cutoff values of 0.8 and 90 g/L, respectively. Also, the sensitivity of new cutoff values for ApoB and ApoB/ApoA1 ratio was higher than the standard value, but the specificity of the standard cutoff values for both was higher than our new cutoff value. CONCLUSIONS: Serum Lp(a) and ApoA1 levels were independently associated with DR, and serum ApoB correlated with severity of DR. These measurements can be used for assessment and early treatment of this vision-threatening complication of diabetes.

PURPOSE: Sexual dysfunction has been ignored in adults with attention-deficit hyperactivity disorder (A-ADHD). This study examined sexual function in adults with ADHD compared to a healthy control group. DESIGN AND METHODS: The experimental group (N = 63, mean age = 31.11 ± 4.29, females = 31) were recruited among referrals with ADHD to an outpatient A-ADHD clinic. The DIVA-2 (Diagnostic Interview for ADHD in adults) and the schedule for affective disorders and schizophrenia (SADS) were used to assess for A-ADHD and comorbid psychiatric disorders, respectively. The healthy groups (N = 66, mean age = 31.37 ± 4.30, females = 31) were demographically matched and had no psychiatric disorders based on the Conners' Adult ADHD Rating Scales-Self Report, Short Version and SADS. Sexual functions were evaluated using the Female Sexual Function Index (FSFI) for females and International Index of Erectile Function (IIEF) for males. FINDINGS: Females with ADHD compared to the control group showed significantly (P < .001) poorer scores in all FSFI domains (desire, arousal, orgasm, satisfaction, pain, and lubrication). The IIEF mean scores in the males with A-ADHD were lower (P = .00) than their counterparts for all the subscales including orgasm, erectile function, intercourse satisfaction, and overall satisfaction, except for the desire (P = .75). The orgasmic function had a significant negative correlation with Conners Adult ADHD Rating Scale-Self Report: Short total scores in males (r = -.48) and females (r = -.40). PRACTICE IMPLICATIONS: This study provides preliminary information on greater difficulties with sexual function in adults with ADHD. Assessment of sexual function in referrals with A-ADHD is suggested.

BACKGROUND: Frequent premature ventricular contractions (PVC) can result in PVCinduced cardiomyopathy (PVC-iCMP), leading to reduced Left Ventricular Ejection Fraction (LVEF) that can be improved by radiofrequency catheter ablation (RFCA). We performed a systematic review to determine the variables predicting LVEF improvement after RFCA in PVCiCMP. METHODS: We developed a "population, intervention, outcome and predictive factors" framework and searched MEDLINE, Embase, Cochrane Library, Cochrane Collaboration and Cochrane Database of Systematic Reviews (CDSR) for full-text, peer-reviewed publications. These publications addressing predictive factors of LVEF improvement showed ≥5% improvement only if deemed significant by the respective study, ≥10% or ≥ 50% after RFCA ablation in patients with PVCiCMP with no type/date/language limitation until the end of 2017. RESULTS: Our initial search yielded 2226 titles, 1519 of which remained after removing the duplicates. Finally, 11 articles - 2 cohorts, 7 quasi-experimental studies, 1 case-control and 1 metaanalysis- were included. Sustained successful ablation, higher baseline PVC burden, LVEF, QRS duration, post-PVC systolic blood pressure rise and post-PVC pulse pressure change, the absence of an underlying cardiomyopathy, younger age, and variability of the frequency of PVCs during the day and lower left ventricular end-diastolic diameter (LVEDD) have been suggested as predictive factors for LVEF improvement in patients with PVC-iCMP. CONCLUSION: The mentioned factors may all be useful to identify PVC-iCMP patients who would benefit from RFCA, although the evidence is not yet strong enough.
