Impact of Cerebral Embolic Protection Devices on Disabling Stroke After TAVR: Updated Results From the STS/ACC TVT Registry.

BACKGROUND: Cerebral embolic protection devices (EPDs) were developed to mitigate the risk of stroke during transcatheter aortic valve replacement (TAVR), but their benefit remains unproven. In the PROTECTED-TAVR trial (Stroke Protection With Sentinel During Transcatheter), EPD use did not reduce periprocedural stroke (primary study outcome) but led to a 62% reduction in the secondary end point of disabling stroke. Given these results, the impact of EPDs during TAVR remains unclear. METHODS: We used STS/ACC TVT registry data to examine the association between EPD use and a proxy for disabling stroke among transfemoral TAVR patients between January 2018 and June 2023. The primary outcome was in-hospital disabling stroke-defined as stroke associated with either in-hospital death or discharge to a nonhome location. We evaluated the association between EPD use and disabling stroke using instrumental variable analysis with a site-level preference for EPD use as the instrument-a quasi-experimental approach that can support causal inference. In addition, we performed a propensity score-based comparison using overlap weighting as a secondary analysis. RESULTS: The study population consisted of 414 649 patients of whom 53 389 (12.9%) received an EPD. The unadjusted rate of in-hospital disabling stroke was 0.7% among the EPD group and 0.9% in the no-EPD group. EPD use was associated with a reduction in disabling stroke in both instrumental variable analysis (relative risk, 0.87 [95% CI, 0.73-1.00]) and propensity-weighted analysis (odds ratio, 0.79 [95% CI, 0.70-0.90]) but was not associated with a reduction in nondisabling stroke. In subgroup analyses, the benefit of EPD was greater among those with versus without prior stroke (Pinteraction<0.05 for both instrumental variable and propensity-weighted analyses). CONCLUSIONS: In the largest study to date, among patients undergoing TAVR, EPD use was associated with a small, borderline significant reduction in stroke associated with death or discharge to a nonhome location (a proxy for disabling stroke) that is likely to be causal in nature. Taken together with previous mechanistic and clinical studies, these findings provide credible evidence that EPDs benefit patients undergoing TAVR.

Outcomes With Belatacept Exposure During Pregnancy in Kidney Transplant Recipients: A Case Series.

BACKGROUND: Posttransplant fertility returns quickly, and female recipients of child-bearing age may conceive while on immunosuppression. However, pregnancy after transplantation confers risks to the recipient, transplant, and fetus, including gestational hypertension, preeclampsia, gestational diabetes, transplant dysfunction, preterm labor, and low birthweight infants. Additionally, mycophenolic acid (MPA) products are teratogenic. Literature evidence regarding belatacept, a selective T-cell costimulation blocker, during pregnancy and while breastfeeding is extremely limited. When female transplant recipients on a belatacept-based regimen are desirous of pregnancy or at the time of conception, transplant providers manage the immunosuppression regimen in 1 of 2 ways: (1) switch both belatacept and MPA to a calcineurin inhibitor-based regimen with or without azathioprine, which is the more common practice but requires several modifications, having potential negative outcomes; or (2) only switch MPA to azathioprine while continuing belatacept. METHODS: This case series includes 16 pregnancies in 12 recipients with exposure to belatacept throughout pregnancy and while breastfeeding. Patient information was obtained from several sources, including Transplant Pregnancy Registry International, providers at Emory University, and Columbia University, as well as literature review. RESULTS: Pregnancy outcomes included 13 live births and 3 miscarriages. No birth defects or fetal deaths were reported in any of the live births. Seven infants were breastfed while their mothers continued belatacept. Outcomes appear comparable to those documented with the administration of calcineurin inhibitors. CONCLUSIONS: This case series provides data supporting the continued administration of belatacept during pregnancy. Additional research will assist in developing better guidelines to counsel female transplant recipients on belatacept desiring to pursue pregnancy.

Factors associated with complications after percutaneous nephrolithotomy: an analysis of 1,066 cases.

OBJECTIVE: The aim of this study was to identify predictive factors for complications after percutaneous nephrolithotomy. METHODS: We prospectively analyzed patients who underwent percutaneous nephrolithotomy from June 2011 to October 2018. The association of preoperative and intraoperative factors with the presence of complications was assessed using univariate and multivariate analyses. The significance level was set at p<0.05. RESULTS: A total of 1,066 surgeries were evaluated, and the overall complication rate was 14.9%. In all, 105 (9.8%) surgeries were performed in the prone position, and 961 (90.2%) were performed in the supine position. Univariate analysis demonstrated that surgical position, upper pole puncture, surgical time, number of tracts, and Guys Stone Score were associated with complications. In multivariate analyses, prone position (odds ratio [OR] 2.10; p=0.003), surgical time ≥90 min (OR 1.76; p=0.014), upper pole puncture (OR 2.48; p<0.001), and Guys Stone Score 3 or 4 (OR 1.90; p=0.033) were independent predictive factors for complications after percutaneous nephrolithotomy. CONCLUSION: Performing percutaneous nephrolithotomy in the supine position, in under 90 min, and avoiding upper pole punctures may reduce complications during the treatment of large kidney stones.

Ultrasound guided endoscopic combined Intrarenal surgery - 10 steps for the success

ABSTRACT Background: Endoscopic combined intrarenal surgery (ECIRS) has been used to treat complex kidney stones (1). The combined use of ultrasound (US) has the potential to improve safety and reduce radiation exposure, however, it is still underutilized (2). Objectives: Our objective is to describe, in a step-by-step manner, the ultrasound-guided ECIRS (USG ECIRS) technique, in order to facilitate learning by urologists. Materials and Methods: We describe the 10 standardized steps that we recommend to achieve a good outcome, based on our previous experience on a high-volume kidney stone center. We recorded a case of a 37-year-old female patient with complex bilateral kidney stones that underwent a left simultaneous combined retrograde and antegrade approach. The 10 described steps are: 1 - case evaluation with CT scan (3); 2 - preoperative care with antibiotics and tranexamic acid; 3 - warm-up and training with phantoms; 4 - patient positioning in Barts flank free position; 5 - retrograde nephroscopy with flexible ureteroscope; 6 - US and endoscopic guided puncture; 7 - tract dilation under endoscopic view; 8 - stone fragmentation; 9 - status free checking and 10, kidney drainage. Images were captured by external and internal cameras, promoting a complete understanding of the procedure. The patient has signed a written informed consent form. Results: Puncture was achieved under US guidance with one attempt. Another puncture was necessary in the lower pole, parallel to the initial puncture, due to a large fragment. Surgical time was 140 min. Stone-free status was verified by retrograde and antegrade view. Kidney drainage was done with ureteral stent on string, removed after 7 days. Hb drop was 1.1 Hb/dL. The first postoperative day CT scan showed no residual stones and no complications. The patient was discharged after the CT and urethral catheter removal. Conclusion: The USG ECIRS seems to be a very efficient and reproducible technique for the treatment of complex kidney stones. Its use should be widespread.

Predictive factors for success after supine percutaneous nephrolithotomy: an analysis of 961 patients.

OBJECTIVE: The aim of this study was to evaluate the predictive factors for success following percutaneous nephrolithotomy in the supine position. METHODS: Patients who underwent percutaneous nephrolithotomy in the supine position from June 2011 to October 2018 were evaluated. Age, sex, body mass index, the American Society of Anesthesiologists physical status classification, hemoglobin level, number of previous surgeries, stone size, and the Guy's Stone Score were analyzed. Success was considered if no fragments were observed on the computed tomography scan on the first postoperative day. Univariate and multivariate analyses were performed to determine significant parameters. RESULTS: We evaluated 961 patients; of them, 483 (50.2%) underwent previous stone-related surgery, and 499 (51.9%) had Guy's Stone Score 3 or 4. The overall success rate in a single procedure was 40.7%, and complication rate was 13.7%. The univariate analysis showed that the maximum diameter of the stone (25.10±10 mm; p<0.001), previous percutaneous nephrolithotomy (OR 0.52; p<0.001), number of previous percutaneous nephrolithotomy (OR 0.15; p<0.001), the Guy's Stone Score (OR 0.28; p<0.001), and the number of tracts (OR 0.32; p<0.001) were significant. In the multivariate analysis, the number of previous percutaneous nephrolithotomy (OR 0.54; p<0.001) and the Guy's Stone Score (OR 0.25; p<0.001) were statically significant. CONCLUSIONS: Guy's Stone Score and the number of previous percutaneous nephrolithotomy are predictors of success with the supine position. Complex cases and with previous percutaneous interventions may require technical improvements to achieve higher stone-free rates.

New in vivo model to assess macroscopic, histological, and molecular changes in Peyronie's disease.

BACKGROUND: Peyronie's Disease (PD) is a connective tissue disorder that affects the tunica albuginea (TA) of the penis causing curvature and erectile dysfunction. The pathophysiology is not well understood and, for this reason, treatment options are limited. OBJECTIVE: The aim of the present study is to analyze and compare whether single or multiple instillations of plasma in the TA of rats is capable of triggering macroscopic, histopathological, and molecular changes consistent with PD. MATERIAL/METHODS: Fifty male Wistar rats were divided into four groups: Group 1: a single instillation of plasma in the TA; Group 2: a single instillation of distilled water in the TA; Group 3: four instillations of plasma in the TA (1x per week); and Group 4: four instillations of distilled water in the TA (1× per week). Forty-five days after the last instillation a manual inspection of the corpus cavernosum, a penile erection test and a penectomy were performed to obtain material for histopathological and molecular analysis. RESULTS: It was observed that 31.25% of the rats that received repeated instillations of plasma presented penile curvature according to the erection test, while none of the rats from the control group or group with one instillation of plasma presented curvature. In the animals that received four instillations of plasma, the following differences were observed in relation to the control group: increase in fibrosis and the deposition of collagen I. The protein expression of heparanase (HPSE) and TGF-ß increased in the groups that received a single or four instillations of plasma, and the protein expression of heparanase-2 (HPSE-2), metalloproteinases (MMP-2, MMP-9) and metalloproteinase inhibitor (TIMP-2) showed an increase in the group that received four instillations of plasma. There was a significant increase in the gene expression of HPSE, MMP-9, and TGF-ß in the group that received four instillations of plasma. In the analysis of the glycosaminoglycans, an increase was observed in the secretion of galactosaminoglycans chondroitin sulfate and dermatan sulfate (CS/DS) in the group that received four instillations of plasma. DISCUSSION: Previous studies have demonstrated increased protein expression. of HPSE, MMP-9 and TGF-ß with instillation of blood in the TA; however, there was no increase in gene expression. In the present study, the increase in the expression of TGF-ß with plasma instillations, proved to be more reliable. The two models with plasma (one or four instillations) demonstrated significant histopathological and molecular changes when compared to the control group. However, only in the group with four plasma instillations there was a macroscopic change. The idea is that repeatedly extravasation of TGF-ß present in plasma of predisposed individuals acts as a trigger for the development and maintenance of changes in the extracellular matrix that perpetuate an anomalous inflammatory process present in PD. CONCLUSION: The present study shows that the repeated instillation of plasma is a low cost in vivo model for the study of PD.

Supine versus Prone Percutaneous Nephrolithotomy for Complex Stones: A Multicenter Randomized Controlled Trial.

PURPOSE: High-quality evidence comparing supine to prone percutaneous nephrolithotomy (PCNL) for the treatment of complex stones is lacking. This study aimed to compare the outcomes of supine position (SUP) and prone position (PRO) PCNL. MATERIALS AND METHODS: A noninferior randomized controlled trial was performed according to the CONSORT (Consolidated Standards for Reporting Trials) criteria. The inclusion criteria were patients over 18 years of age with complex stones. SUP was performed in the Barts flank-free modified position. Except for positioning, all the surgical parameters were identical. The primary outcome was the difference in the success rate on the first postoperative day (POD1) between groups. The secondary outcome was the difference in the stone-free rate (SFR) on the 90th postoperative day (final SFR). A noninferiority margin of 15% was used. Demographic, operative, and safety variables were compared between the groups. Statistical significance was set at p <0.05. RESULTS: Overall, 112 patients were randomized and their demographic characteristics were comparable. The success rates on POD1 were similar (SUP: 62.5% vs PRO: 57.1%, p=0.563). The difference observed (-5.4%) was lower than the predefined limit. The final SFRs were also similar (SUP: 55.4% vs PRO: 50.0%, p=0.571). SUP had a shorter operative time (mean±SD 117.9±39.1 minutes vs 147.6±38.8 minutes, p <0.001) and PRO had a higher rate of Clavien ≥3 complications (14.3% vs 3.6%, p=0.045). CONCLUSIONS: Positioning during PCNL for complex kidney stones did not impact the success rates; consequently, both positions may be suitable. However, SUP might be associated with a lower high-grade complication rate.

Treatment compliance and risk and protective factors for suicide ideation to completed suicide in adolescents: a systematic review

Objective: To review the literature regarding adolescent suicide risk and explore the associations between treatment compliance (expressed as a concept including measured adherence to treatment and/or mental health service utilization) and risk and protective factors for suicidal behavior (SB), as well as the association between treatment compliance and reattempts. Methods: PubMed, LILACS, and Google Scholar were searched using the following terms: (adolescent*) AND (suicide*) AND (risk factor OR protective factors) AND (treatment compliance OR treatment attrition OR treatment adherence OR treatment drop out OR treatment retention OR mental health utilization). We retrieved studies that focused on the relation of treatment compliance to risk and protective factors for SB and that had only adolescent samples. Results: Of 4,841 articles, 30 original articles were selected for review. Most studies indicated high mental health service (MHS) utilization and poor treatment adherence by SB patients. Social minority status and conduct disorder were associated with less treatment adherence, while female sex, parental perceived need for treatment, and major depression were associated with greater treatment adherence. Inpatient and intensive emergency care after SA and family interventions improved MHS utilization and treatment compliance. However, we found no substantial protective effect of treatment compliance against reattempts. Conclusion: Effective treatment planning for compliance requires considering psychopathology, treatment planning, and social, familial, and individual factors.

"Motherese" Prosody in Fetal-Directed Speech: An Exploratory Study Using Automatic Social Signal Processing.

Introduction: Motherese, or emotional infant directed speech (IDS), is the specific form of speech used by parents to address their infants. The prosody of IDS has affective properties, expresses caregiver involvement, is a marker of caregiver-infant interaction quality. IDS prosodic characteristics can be detected with automatic analysis. We aimed to explore whether pregnant women "speak" to their unborn baby, whether they use motherese while speaking and whether anxio-depressive or obstetrical status impacts speaking to the fetus. Participants and Methods: We conducted an observational study of pregnant women with gestational ages from 26 to 38 weeks. Women were recruited in a university hospital department of obstetrics. Thirty-five women agreed to participate in the study, and 26 audio records were exploitable. We collected obstetrical and sociodemographic data, pregnancy outcomes, anxiety and depressive status using the Covy and Raskin Scales, and life events using the Sensations During Pregnancy and Life Event Questionnaire. Each participant was left alone with an audio recorder with a recommendation to feel free to speak to her fetus as she would have done at home. The recording was stopped after 3 min. Audio recordings were analyzed by two methods: psycholinguist experts' annotation and computational objective automatic analyses. Results: Most mothers (89%) reported speaking to their fetuses. We found a correlation between maternal first perceptions of fetal movements and the start of mother's speaking to fetus. Motherese prosody was detected with both annotation and automatic analysis with a significant correlation between the two methods. In this exploratory study, motherese use was not associated with maternal anxiodepressive or obstetrical status. However, the more future mothers were depressed, the less they spoke with their fetuses during the recording. Conclusion: Fetal directed speech (FDS) can be detected during pregnancy, and it contains a period of prosody that shares the same characteristics of motherese that can be described as prenatal motherese or emotional fetal-directed speech (e-FDS). This means that pregnant women start using motherese much earlier than expected. FDS seems to be correlated with maternal first perceptions of fetal movements and depression scores. However, more research is needed to confirm these exploratory results.

Suicide Attempts Among French and Brazilian Adolescents Admitted to an Emergency Room. A Comparative Study of Risk and Protective Factors.

BACKGROUND: Suicide is the second most common cause of preventable mortality among Brazilian and French adolescents. The aim of the current study was to compare the main risk and protective factors associated with a suicide attempt (SA) and to highlight differences based on geographical characteristics. METHOD: We compared a Brazilian sample (N = 45) of adolescents admitted to the emergency room of a public hospital in São Paulo for SA to a French sample (N = 320) of adolescents hospitalized for SA across 5 paediatric departments. Then, we ran several multivariate models to examine how each selected variable was related to geographic origin and to the other selected variables linked to geographic origin. RESULTS: The two samples presented no significant differences regarding gender, age or schooling. Both samples had high rates of depressive disorders, anxiety disorders, substance use, disruptive disorders, borderline psychopathology, and lifetime SAs. However, the Brazilian sample presented significantly higher levels of psychopathology and had more insecure attachment relationships (fearful and detached), whereas the French sample had a more secure attachment style. Brazilian adolescents had more recourse to spiritual beliefs and spiritual support, whereas the French adolescents had higher scores on the Reasons for Living Inventory and used more help-seeking strategies from their social network, mainly close friends. Multivariate models showed that two productive coping strategies (seeking spiritual support and social action) and the dependence score were significantly associated with membership in the Brazilian cohort, whereas a secure attachment style and depression severity (evaluated by the Beck Depression Inventory) were significantly associated with membership in the French cohort. CONCLUSION: Despite presenting similar psychopathologies, Brazilian adolescents presented a more insecure attachment style and used the religious kind of coping more commonly than their French counterparts. We hypothesize that religion may compensate for the social vulnerabilities present in a middle-income country such as Brazil. More transcultural studies may help to elucidate this phenomenon.

Extracellular matrix alterations after blood instillation in tunica albuginea of rats.

The cause of Peyronie's disease (PD) is still not completely understood. The objective of this study, therefore, was to analyze the histological and biochemical alterations that occur after the instillation of blood in the tunica albuginea (TA) of rats with an emphasis on the remodeling process of ECM. Thirty male Wistar rats were divided into 4 groups: two control groups with instillation of distilled water in TA followed by penectomy after 15 days or 45 days, respectively and two experimental groups with instillation of blood in TA followed by penectomy after 15 days or 45 days, respectively. Histological, immunofluorescent and immunohistochemical analyses were performed. The higher presence of fibrotic tissue in rats injected with blood demonstrated alterations in TA similar to inflammation found in PD. The increased expression of TGF-ß, MMP9, HPSE, and biglycan associated with the decreased expression of syndecan-1 and aggrecan in the experimental groups suggested an enhancement in the remodeling of ECM. The results contribute to show that blood instillation on TA appears to trigger alterations in the ECM similar to the ones found in inflammatory diseases such as PD.

Appropriate patient selection or health care rationing? Lessons from surgical aortic valve replacement in the Placement of Aortic Transcatheter Valves I trial.

OBJECTIVES: The study objectives were to (1) compare the safety of high-risk surgical aortic valve replacement in the Placement of Aortic Transcatheter Valves (PARTNER) I trial with Society of Thoracic Surgeons national benchmarks; (2) reference intermediate-term survival to that of the US population; and (3) identify subsets of patients for whom aortic valve replacement may be futile, with no survival benefit compared with therapy without aortic valve replacement. METHODS: From May 2007 to October 2009, 699 patients with high surgical risk, aged 84 ± 6.3 years, were randomized in PARTNER-IA; 313 patients underwent surgical aortic valve replacement. Median follow-up was 2.8 years. Survival for therapy without aortic valve replacement used 181 PARTNER-IB patients. RESULTS: Operative mortality was 10.5% (expected 9.3%), stroke 2.6% (expected 3.5%), renal failure 5.8% (expected 12%), sternal wound infection 0.64% (expected 0.33%), and prolonged length of stay 26% (expected 18%). However, calibration of observed events in this relatively small sample was poor. Survival at 1, 2, 3, and 4 years was 75%, 68%, 57%, and 44%, respectively, lower than 90%, 81%, 73%, and 65%, respectively, in the US population, but higher than 53%, 32%, 21%, and 14%, respectively, in patients without aortic valve replacement. Risk factors for death included smaller body mass index, lower albumin, history of cancer, and prosthesis-patient mismatch. Within this high-risk aortic valve replacement group, only the 8% of patients with the poorest risk profiles had estimated 1-year survival less than that of similar patients treated without aortic valve replacement. CONCLUSIONS: PARTNER selection criteria for surgical aortic valve replacement, with a few caveats, may be more appropriate, realistic indications for surgery than those of the past, reflecting contemporary surgical management of severe aortic stenosis in high-risk patients at experienced sites.

Diagnosis of erectile dysfunction.

PURPOSE OF REVIEW: Erectile dysfunction is a very prevalent condition and impairs quality of life of men and their partners. The diagnosis strategy of erectile dysfunction has changed, and it is important for every health professional to learn how to deal with erectile dysfunction. RECENT FINDINGS: Although very prevalent, the sexual dysfunctions, including erectile dysfunction, continue to be underdiagnosed. Patients often expect physicians to initiate the conversation and ask about their troubles having sex. The routine to identify erectile dysfunction causes has undergone significant changes over the last decade. Identification of erectile dysfunction can be made through questionnaires or a complete medical and sexual history. Anamnesis and laboratory tests are sufficient in most cases to identify erectile dysfunction and to manage the treatment. Supplementary tests are used in special cases or when there is a need for an etiological diagnosis. SUMMARY: Sexual function must be a part of every medical consultation, as any other body function. Erectile dysfunction diagnosis is not a complex task and can be accomplished by any physician. Even when the professional does not feel secure to treat erectile dysfunction, he or she can just identify the dysfunction and refer the patient to an expert.
