Antibiotics prophylaxis at the time of catheter removal after radical prostatectomy: a systematic review of the literature and meta-analysis

Purpose: To conduct a systematic literature review with meta-analysis to identify whether antibiotic prophylaxis after removal of the indwelling urinary catheter reduces posterior infections. Methods: A systematic literature review was conducted in the databases PubMed, Embase, Cochrane, Google Scholar, and Latin American and Caribbean Health Sciences Literature, using the keywords "antibiotics" AND "prostatectomy" AND "urinary catheter." Results: Three articles were identified having the scope of our review, with 1,040 patients, which were subjected to our meta-analysis revealing a marginally significant decrease in the risk of urinary infection after indwelling urinary catheter removal (odds ratio-OR = 0.51; 95% confidence interval-95%CI 0.27-0.98; p = 0.04; I2 = 0%). No difference was found regarding the presence of bacteriuria (OR = 0.39; 95%CI 0.12-1.24; p = 0.11; I2 = 73%). Conclusions: In our meta-analysis, there was a significant decrease in urinary tract infection with antibiotic prophylaxis after indwelling urinary catheter removal following radical prostatectomy.

Tamsulosin vs. Tadalafil as medical expulsive therapy for distal ureteral stones: a systematic review and meta-analysis

ABSTRACT Purpose: Medical expulsive therapy (MET) is recommended for distal ureteral stones from 5 to 10 mm. The best drug for MET is still uncertain. In this review, we aim to compare the effectiveness of tadalafil and tamsulosin for distal ureteral stones from 5 to 10 mm in terms of stone expulsion rate (SER), stone expulsion time (SET) and the side effect profile. Materials and methods: A comprehensive literature search was conducted on MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Scopus and Web of Science, from inception until April 2023. Only randomized controlled trials were included in the analysis. Results: Eleven publications with 1,330 patients were included. We observed that tadalafil has a higher SER (OR 0.55, CI 95% 0.38;0.80, p=0.02, I2=52%) and the same efficacy in SET (MD 1.07, CI 95% -0.25; 2.39, p=0.11, I2=84%). No differences were found when comparing side effects as headache, backache, dizziness, and orthostatic hypotension. Conclusion: Tadalafil has a higher stone expulsion rate than tamsulosin as a medical expulsive therapy for patients with distal stones from 5 to 10 mm without differences in side effects.

Religiosity and Spirituality: The Relationship Between Psychosocial Factors and Cardiovascular Health

Abstract Background: Religiosity and Spirituality (R/S), despite being different entities, are multidimensional constructs, whose influence on cardiovascular health has been increasingly studied in recent decades. Objectives: To discriminate patients into subgroups according to R/S levels, in order to compare them regarding the distribution of cardiovascular comorbidities and clinical events. Methods: This is an observational, cross-sectional, analytical study. Two R/S scales were applied to a sample of patients seen at cardiology outpatient clinics. A cluster analysis was used to discriminate individuals into subgroups regarding R/S levels, which were subsequently compared regarding the frequencies of clinical variables related to cardiovascular health. A significance level of 5% was set for the statistical tests. Results: The sample included 237 patients with a mean age of 60.8 years (±10.7), of which 132 were female (55.7%). Cluster analysis (C) distinguished two groups: C1, with lower levels of R/S, and C2, with higher levels of R/S (p<0.001). C2 had a lower frequency of alcohol consumption (29.5% vs. 76.0%; p<0.001), smoking (12.9% vs. 51.0%; p<0.001), systemic arterial hypertension (SAH — 65.5% vs. 82.3%; p=0.005), dyslipidemia (58.3% vs. 77.1%; p=0.003), chronic coronary syndrome (36.7% vs. 58.3%; p=0.001), and prior cardiovascular events (15.8% vs. 36.5%; p<0.001) when compared to C1. There was also a higher frequency of females in C2 (82.0% vs. 17.7%; p<0.001). Conclusions: A better cardiovascular morbidity profile was observed in the group of patients with higher R/S levels, suggesting a probable positive relationship between R/S and cardiovascular health.

Non-Targeted Self-Measured Blood Pressure and Hypertension Control in Public and Private Health Systems in Brazil

Abstract Background: It is estimated that more than 30% of the Brazilian population has systemic arterial hypertension (SAH), and mostly as an uncontrolled disease. The most recent Brazilian Guideline of Hypertension recommends the practice of self-measurement of blood pressure (BP) as one of the strategies for a better control of SAH, but there is no consensus about the efficiency of this tool. Objective: To assess the control of SAH and the practice of non-targeted self-measured BP (SMBP) among hypertensive users of the Unified Health System (SUS) and the Supplementary Network (SN). Methods: This is a cross-sectional, observational, analytical study, with a stratified probability sample. One thousand volunteers were investigated, being 500 from SUS and 500 from the SN. Uni and multivariate analyses were performed considering a 5% significance level. Results: Patients from SUS presented inferior sociodemographic data (schooling, social status) in relation to those of the SN (p < 0.001), and showed lower control of SAH (p = 0.014), as well as more visits to the emergency room in the past year due to hypertension (p = 0.002), and fewer regular appointments with the cardiologist (p = 0.004). SMBP was equally present in both assessed groups (p = 0.567), even though users of the SN have been more advised to not conduct such a practice (p = 0.002). SMBP (p < 0.001) was an independent factor for uncontrolled SAH both in SUS (OR = 3.424) and in the SN (OR = 3.474). Conclusion: Patients in SUS presented lower SAH control. The practice of SMBP, mostly practiced with an uncalibrated digital device, was equally present in both groups and became an independent factor of uncontrolled SAH.

Patrones de violencia en las relaciones de pareja en adolescentes: una revisión sistemática de la literatura / Patterns of Teen Dating Violence. A Systematic Review of the Literature

Resumen Un grupo creciente de investigaciones ha sugerido la existencia de diferentes patrones de violencia en las relaciones de pareja durante la adolescencia. El objetivo de este estudio fue revisar y sintetizar la evidencia científica respecto a patrones de violencia en las relaciones de pareja en adolescentes, a través de una revisión sistemática de la literatura. La búsqueda se realizó en las bases de datos Pubmed, Scopus, SCIELO, EBSCO, Web of Science, Sage Journals, Taylor and Francis Journals, Wiley, y el motor de búsqueda Google Académico; no hubo restricciones en el año de publicación. Se incluyeron investigaciones que analizaron la violencia desde una perspectiva centrada en la persona (e.g., uso de análisis de clases latentes). Para evaluar la calidad de los estudios transversales se usó la herramienta Axis de 20 ítems, y para los estudios longitudinales, la lista de verificación de Tooth et al. (2005) de 33 ítems. Se identificaron 212 estudios y después de elegir por criterios de elegibilidad, se incluyeron 27. Los patrones de violencia con mayor frecuencia fueron: violencia multiforme (34%), victimización o perpetración por violencia psicológica y física (26%), violencia bidireccional psicológica/verbal (26 °/o), baja violencia (26 °%) y alta violencia (23 °/o). Los patrones de violencia se relacionaron con diferentes variables tales como experiencias adversas en la infancia, variables sociodemográficas, relación familiar e indicadores de salud mental. Estos patrones evidencian que la violencia en las relaciones de pareja durante la adolescencia son un fenómeno complejo y multifactorial.

Abstract A growing body of research has suggested different patterns of teen dating violence. The aim of this study was to review and synthesize the scientific evidence on patterns of teen dating violence, through a systematic review of the literature. The search was conducted in the databases Pubmed, Scopus, SCIELO, EBSCO, Web of Science, Sage Journals, Taylor and Francis Journals, Wiley, and the Google Scholar search engine; there were no restrictions on the year of publication. Studies that indicate analyzing violence from a person-centered perspective (e.g., use of latent class analysis) were included. The 20-item Axis tool was used to assess the quality of the cross-sectional studies, and the 33-itemTooth et al. (2005) Checklist was used for longitudinal studies. Two hundred and twelve studies were identified and after screening for eligibility criteria, 27 studies were included. The most frequent patterns of violence were multiform violence (34%), victimization or perpetration by psychological and physical violence (26%), bidirectional psychological/verbal violence (26%), low violence (26%) and high violence (23%). Violence patterns were related to different variables such as adverse childhood experiences, sociodemographic variables, family relationship, and mental health indicators. These patterns show that teen dating violence is a complex and multifactorial phenomenon.

Eficacia de las terapias online de activación conductual y cognitivo conductual para el tratamiento de la depresión en mujeres mexicanas víctimas de violencia / Efficacy of online behavioral activation and cognitive-behavioral therapies for the treatment of depression in Mexican women victims of violence

Antecedentes: La violencia contra la mujer (VCM) y la pandemia por COVID-19 son problemáticas que han afectado la salud mental de las mujeres, con secuelas como la depresión. Objetivo: Comparar la eficacia del tratamiento breve de activación conductual (BATD) y la terapia cognitiva conductual (TCC) con adaptaciones culturales administradas online (telesalud) para la depresión en víctimas de VCM durante la COVID-19 en México. Método: Se realizó un ensayo clínico aleatorizado con 20 mujeres mexicanas de 18-60 años con depresión que experimentaron VCM en los últimos seis meses durante la COVID-19. Las participantes fueron asignadas de manera aleatorizada 1:1 a los grupos BATD y TCC. Para el análisis de datos se aplicaron las pruebas Friedman y U de Mann-Whitney, y se estimó el Índice de Cambio Confiable. Resultados: Se encontró una disminución en síntomas depresivos (p < .001) e incremento en los niveles de activación (p < .001) a favor del grupo BATD, al término de la intervención y en el seguimiento en contraste con la TCC. Conclusiones: La BATD mostró ser eficaz en crisis de emergencia sanitaria en contextos de VCM. Aunar evidencia de intervenciones eficientes para esta población contribuye a mitigar las afecciones de salud mental.

Background: Violence against women (VAW) and the COVID-19 pandemic are issues that have affected women's mental health, with sequela such as depression. Objective: To compare the efficacy of brief behavioral activation therapy (BATD) and cognitive behavioral therapy (CBT) with cultural adaptations administered online by telehealth for depression in victims of VAW during COVID-19 in Mexico. Method: A randomized clinical trial was conducted with 20 Mexican women aged 18-60 years with depression who experienced VAW in the last six months during COVID-19. Participants were randomized 1:1 to the BATD and CBT groups. For data analysis, Friedman and Mann-Whitney U tests were applied, and the Reliable Change Index was estimated. Results: A decrease in depressive symptoms (p < .001) and an increase in activation levels (p < .001) were found in favor of the BATD group at the end of the intervention and at follow-up, in contrast to CBT. Conclusions: BATD was shown to be effective in health emergency crises in VAW contexts. Gathering evidence of efficient interventions for this population contributes to mitigating mental health conditions.

Non-reperfused ST-elevation myocardial infarction: notions from a low-to-middle-income country / Infarto de miocardio con elevación del ST no reperfundido: nociones de un país de ingresos bajos a medios

Abstract Objective: The objective of the study was to analyze the differences between survivors and non-survivors with non-reperfused ST-segment elevation myocardial infarction (STEMI) and to identify the predictors of in-hospital mortality. Methods: A retrospective cohort study included non-reperfused STEMI patients from October 2005 to August 2020. Patients were classified into survivors and non-survivors. We compared patient characteristics, treatments, and outcomes among the groups and identified factors associated with in-hospital mortality. Results: We included 2442 patients with non-reperfused STEMI and we found a mortality of 12.7% versus 7.2% in reperfused STEMI. The main reason for non-reperfusion was delayed presentation (96.1%). Non-survivors were older, more often women, and had diabetes, hypertension, or atrial fibrillation. The left main coronary disease was more frequent in non-survivors as well as three-vessel disease. Non-survivors developed more in-hospital heart failure, reinfarction, atrioventricular block, bleeding, stroke, and death. The main predictors for in-hospital mortality were renal dysfunction (HR 3.41), systolic blood pressure < 100 mmHg (HR 2.26), and left ventricle ejection fraction < 40% (HR 1.97). Conclusion: Mortality and adverse outcomes occur more frequently in non-reperfused STEMI. Non-survivors tend to be older, with more comorbidities, and have more adverse in-hospital outcomes.

Resumen Objetivo: Analizar las diferencias entre los sobrevivientes y no sobrevivientes con infarto agudo de miocardio no reperfundido y conocer los predictores de mortalidad intrahospitalaria. Métodos: Estudio de cohorte retrospectiva que incluyó pacientes con infarto agudo de miocardio no reperfundido de octubre de 2005 a agosto de 2020. Se clasificaron los pacientes de acuerdo a su estado de sobrevida y se compararon las características clínicas, tratamientos y desenlaces para poder identificar los predictores de mortalidad intrahospitalaria. Resultados: Se incluyeron 2442 pacientes con infarto agudo de miocardio no reperfundido, en los que se encontró una mortalidad de 12.7% vs 7.2% los que si recibieron tratamiento de reperfusión. La principal razón para no recibir tratamiento de reperfusión fue el retraso en la atención médica (96.1%). Los no sobrevivientes tuvieron mayor edad, fueron mujeres y tuvieron mayor frecuencia de diabetes, hipertensión y fibrilación atrial. El tronco de la coronaria izquierda y la enfermedad trivascular fueron más frecuentes en los que no sobrevivieron. Los pacientes que no sobrevivieron desarrollaron más insuficiencia cardiaca, reinfarto, bloqueo atrioventricular, sangrados, evento vascular cerebral y muerte. Los principales predictores de mortalidad intrahospitalaria fueron: insuficiencia renal (HR 3.41), tensión arterial sistólica al ingreso < 100 mmHg (HR 2.26) y fracción de eyección del ventrículo izquierdo < 40% (HR 1.97). Conclusiones: Los pacientes con infarto de miocardio no reperfundido tienen mayor mortalidad y desenlaces adversos. Los no sobrevivientes fueron mayores, con más comorbilidades y desarrollaron más desenlaces adversos intrahospitalarios.

Vasopressin in vasoplegic shock in surgical patients: systematic review and meta-analysis

Purpose: Vasoplegia, or vasoplegic shock, is a syndrome whose main characteristic is reducing blood pressure in the presence of a standard or high cardiac output. For the treatment, vasopressors are recommended, and the most used is norepinephrine. However, new drugs have been evaluated, and conflicting results exist in the literature. Methods: This is a systematic review of the literature with meta-analysis, written according to the recommendations of the PRISMA report. The SCOPUS, PubMed, and ScienceDirect databases were used to select the scientific articles included in the study. Searches were conducted in December 2022 using the terms "vasopressin," "norepinephrine," "vasoplegic shock," "postoperative," and "surgery." Meta-analysis was performed using Review Manager (RevMan) 5.4. The endpoint associated with the study was efficiency in treating vasoplegic shock and reduced risk of death. Results: In total, 2,090 articles were retrieved; after applying the inclusion and exclusion criteria, ten studies were selected to compose the present review. We found no significant difference when assessing the outcome mortality comparing vasopressin versus norepinephrine (odds ratio = 1.60; confidence interval 0.47-5.50), nor when comparing studies on vasopressin versus placebo. When we analyzed the length of hospital stay compared to the use of vasopressin and norepinephrine, we identified a shorter length of hospital stay in cases that used vasopressin; however, the meta-analysis did not demonstrate statistical significance. Conclusions: Considering the outcomes included in our study, it is worth noting that most studies showed that using vasopressin was safe and can be considered in managing postoperative vasoplegic shock.

Does displacement of lower pole stones during retrograde intrarenal surgery improves stone-free status?: a systematic review and meta-analysis

Purpose: Kidney stones are one of the most common urological diseases worldwide. The size and location of the stone are the most important factors in determining the most suitable treatment options. The aim of this review was to evaluate the displacement of lower pole stones. Methods: Three studies assessing the efficacy of translocating kidney stones from the lower pole of the kidney to other locations during retrograde intrarenal surgery published in the last 20 years were included. A systematic search was conducted in the PubMed, Embase, Latin American and Caribbean Health Sciences Literature (LILACS), and Web of Science databases using the following search terms: "Lower pole," "Lithotripsy." Meta-analysis was performed using Review Manager version 5.4. Results: Stone-free rates were improved through displacement (odds ratio - OR = -0.15; 95% confidence interval-95%CI -0.24--0.05; p = 0.002; I2 = 21%), but at the cost of increased surgical duration (mean difference = -12.50; 95%CI -24.06--0.95; p = 0.03; I2 = 94%). Although this represents a potentially negative outcome, the improvement in clearance rates justifies the additional investment of time and effort. Conclusions: Displacement of lower pole kidney stones for subsequent lithotripsy brings significant benefits in terms of stone-free rate, with no difference in laser energy usage. However, it results in increased surgical time. Despite these factors, the benefits to patients undergoing the procedure are substantial.

Comparing financing models for supplementary healthcare in appendectomy: activity-based costing (fee-for-service) vs. diagnosis related group remuneration (bundled payment): a systematic review and meta-analysis

Purpose: In Brazil, healthcare services traditionally follow a fee-for-service (FFS) payment system, in which each medical procedure incurs a separate charge. An alternative reimbursement with the aim of reducing costs is diagnosis related group (DRG) remuneration, in which all patient care is covered by a fixed amount. This work aimed to perform a systematic review followed by meta-analysis to assess the effectiveness of the Budled Payment for Care Improvement (BPCI) versus FFS. Methods: Our work was performed following the items of the PRISMA report. We included only observational trials, and the primary outcome assessed was the effectiveness of FFS and DRG in appendectomy considering complications. We also assessed the costs and length of hospital stay. Meta-analysis was performed with Rev Man version 5.4. Results: Out of 735 initially identified articles, six met the eligibility criteria. We demonstrated a shorter hospital stay associated with the DRG model (mean difference = 0.39; 95% confidence interval ­ 95%CI ­ 0.38­0.40; p < 0.00001; I2 = 0%), however the hospital readmission rate was higher in this model (odds ratio = 1.57; 95%CI 1.02­2.44, p = 0.04; I2 = 90%). Conclusions: This study reveals a potential decrease in the length of stay for appendectomy patients using the DRG approach. However, no significant differences were observed in other outcomes analysis between the two approaches.

Colecistitis aguda asociada con COVID-19 grave en el embarazo. Reporte de caso y revisión de la bibliografía / Acute cholecystitis associated with severe COVID-19 in pregnancy. Case report and bibliographic review

Resumen ANTECEDENTES: Las mujeres embarazadas e infectadas con SARS-CoV-2 tuvieron 2.9 veces más probabilidad de requerir ventilación invasiva. La colecistitis aguda es la segunda indicación quirúrgica más común en el embarazo. En la búsqueda bibliográfica no se encontraron reportes de concomitancia de ambas enfermedades durante el embarazo, por este motivo se publica el reporte de caso clínico y se revisa la bibliografía. CASO CLÍNICO: Paciente de 32 años, en curso de las 23 semanas de embarazo. Debido a síntomas de COVID-19, con prueba PCR positiva, se hospitalizó para inicio de ventilación mecánica invasiva. Al noveno día de internamiento tuvo elevación de transaminasas y reporte de TAC de colecistitis aguda alitiásica. Se le indicó la colecistostomía percutánea, con la que se alivió el cuadro hepatobiliar. En el segundo tiempo quirúrgico se procedió a la cesárea. Tres días después experimentó mejoría ventilatoria y bioquímica gradual. A los 32 días de hospitalización se logró la intubación y, después de 54 días, se dio de alta del hospital, sin requerimiento de oxígeno suplementario. CONCLUSIONES: Encontrar, en conjunto con el síndrome de insuficiencia respiratoria aguda por COVID-19 grave que requiere ventilación mecánica invasiva, embarazo previable y colecistitis alitiásica pone en grave peligro a la embarazada y al equipo médico en múltiples dilemas médicos, quirúrgicos y bioéticos. La colecistostomía percutánea en pacientes con inestabilidad hemodinámica y la finalización del embarazo en caso de deterioro ventilatorio ante síndrome de insuficiencia respiratoria aguda es una opción controvertida. Lo conducente, sin duda, son los procedimientos basados en evidencia y las sesiones multidisciplinarias, incluyendo a la familia.

Abstract BACKGROUND: Pregnant women infected with SARS-CoV-2 were 2.9 times more likely to require invasive ventilation. Acute cholecystitis is the second most common surgical indication in pregnancy. In the literature search, no reports of concomitance of both diseases during pregnancy were found, for this reason the clinical case report is published and the literature is reviewed. CASE REPORT: 32-year-old female patient, in the course of 23 weeks of pregnancy. Due to symptoms of COVID-19, with positive PCR test, she was hospitalized for initiation of invasive mechanical ventilation. On the ninth day of hospitalization, she had elevated transaminases and CT report of acute cholecystitis alliasis. Percutaneous cholecystostomy was indicated, which relieved the hepatobiliary symptoms. In the second surgical stage, a cesarean section was performed. Three days later she experienced gradual ventilatory and biochemical improvement. After 32 days of hospitalization, intubation was achieved and, after 54 days, she was discharged from the hospital, without requiring supplemental oxygen. CONCLUSIONS: Finding, in conjunction with severe COVID-19 acute respiratory failure syndrome requiring invasive mechanical ventilation, pre-viable pregnancy, alliasic cholecystitis, places the pregnant woman and the medical team in serious medical, surgical, and bioethical dilemmas. Percutaneous cholecystostomy in patients with hemodynamic instability and termination of pregnancy in case of ventilatory deterioration in the face of acute respiratory failure syndrome is a controversial option. Evidence-based procedures and multidisciplinary sessions, including the family, are undoubtedly conducive.

Linfoma de células B de alto grado de malignidad con morfología blastoide durante el embarazo: reporte de un caso / High-grade malignant B-Cell lymphoma with blastoid during pregnancy: a case report

Resumen ANTECEDENTES: Durante el embarazo es más común el linfoma de Hodking que el no Hodking; afecta, en promedio, a mujeres de 30 años (18-44 años) y más. Suele diagnosticarse alrededor de las 28 semanas de embarazo y está documentado que puede llegarse al término. Los esquemas de tratamiento pueden iniciarse en el posparto inmediato o, incluso, antes. La incidencia mundial del linfoma no Hodking es de 0.8 por cada 100,000 mujeres; se desconoce la supervivencia durante el embarazo. CASO CLINICO: Paciente de 34 años, con antecedentes obstétricos de tres embarazos, una cesárea y un aborto y el embarazo actual en curso de las 29 semanas, referida de la ciudad de Colima debido a un reporte de BI-RADS 3 en el ultrasonido de mama y un nódulo mamario palpable, con evidencia de múltiples tumoraciones en la zona hepática, esplénica y peripancreática. La biopsia tomada de las zonas de la lesión reportó: linfoma de células B de alto grado de malignidad, con morfología blastoide y expresión de C-MYC y BCL2. Además, la paciente se encontró con: anemia, dolor abdominal, múltiples nódulos hepáticos y adenopatías abdominales. Se decidió la interrupción del embrazo a las 30 semanas, con la obtención de un recién nacido, sin complicaciones. Enseguida se inició el tratamiento con rituximab-etopósido-prednisolona-vincristina-ciclofosfamida-doxorrubicina (R-EPOCH) con adecuada adaptación por la paciente. CONCLUSION: Puesto que la información bibliográfica de linfoma y embarazo es escasa el caso aquí reportado es relevante por su aporte. La atención multidisciplinaria favorecerá siempre el pronóstico de las pacientes.

Abstract BACKGROUND: Hodking's lymphoma is more common during pregnancy than non-Hodking's lymphoma; it affects, on average, women aged 30 years (18-44 years) and older. It is usually diagnosed around 28 weeks of pregnancy and is documented to be carried to term. Treatment regimens can be initiated in the immediate postpartum period or even earlier. The worldwide incidence of non-Hodking's lymphoma is 0.8 per 100,000 women; survival during pregnancy is unknown. CLINICAL CASE: 34-year-old patient, with obstetric history of three pregnancies, one cesarean section and one abortion and the current pregnancy in progress at 29 weeks, referred from the city of Colima due to a report of BI-RADS 3 on breast ultrasound and a palpable breast nodule, with evidence of multiple tumors in the hepatic, splenic and peripancreatic area. Biopsy taken from the lesion areas reported: high grade malignant B-cell lymphoma, with blastoid morphology and expression of C-MYC and BCL2. In addition, the patient was found to have: anemia, abdominal pain, multiple hepatic nodules and abdominal adenopathies. It was decided to terminate the pregnancy at 30 weeks, with the delivery of an uncomplicated newborn. Rituximab-Etoposide, Prednisone, Vincristine, Cyclophosphamide, and Doxorubicin (R-EPOCH) therapy was started immediately with adequate adaptation by the patient. CONCLUSION: Since bibliographic information on lymphoma and pregnancy is scarce, the case reported here is relevant for its contribution. Multidisciplinary care will always favor the prognosis of patients.

Diameter of ureteral access sheath and ureteral stenosis development: a systematic review

Purpose: Ureteral access sheaths (UAS) are widely used in ureteroscopy. UAS are believed to pose a significant risk for ureteral stenosis due to ureteral mucosal compression, but little evidence supports this claim. Our systematic review aimed to investigate the relationship between different UAS diameters and stenosis risk. Methods: A systematic search was conducted in PubMed, Embase, Web of Science, Scopus, and Cochrane, from its inception to May 2023. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and Cochrane guidelines were followed. χ2 test was performed to compare the prevalence within the groups. Results: Six nonrandomized trials and one randomized, with a total of 962 patients, were included. The overall incidence of ureteral stenosis of 0.9%. UAS sizes were: 9.5/11.5Fr, 10/12Fr, 11/13Fr, 12/14Fr, and 14/16Fr. Within each subgroup, the incidence of ureteral stenosis was: 0.4, 8, 0, 1, and 1% (p = 0.099). No trend for stenosis was observed among larger UAS. Conclusions: In this systematic review, no relationship between UAS diameter and incidence of ureteral stenosis was observed. Nonetheless, additional randomized controlled trials are required to support this finding.

Use of artificial intelligence for sepsis risk prediction after flexible ureteroscopy: a systematic review / Uso da inteligência artificial na predição do risco de sepse pós-ureteroscopia flexível: uma revisão sistemática

ABSTRACT Introduction: flexible ureteroscopy is a minimally invasive surgical technique used for the treatment of renal lithiasis. Postoperative urosepsis is a rare but potentially fatal complication. Traditional models used to predict the risk of this condition have limited accuracy, while models based on artificial intelligence are more promising. The objective of this study is to carry out a systematic review regarding the use of artificial intelligence to detect the risk of sepsis in patients with renal lithiasis undergoing flexible ureteroscopy. Methods: the literature review is in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). The keyword search was performed in MEDLINE, Embase, Web of Science and Scopus and resulted in a total of 2,496 articles, of which 2 met the inclusion criteria. Results: both studies used artificial intelligence models to predict the risk of sepsis after flexible uteroscopy. The first had a sample of 114 patients and was based on clinical and laboratory parameters. The second had an initial sample of 132 patients and was based on preoperative computed tomography images. Both obtained good measurements of Area Under the Curve (AUC), sensitivity and specificity, demonstrating good performance. Conclusion: artificial intelligence provides multiple effective strategies for sepsis risk stratification in patients undergoing urological procedures for renal lithiasis, although further studies are needed.

RESUMO Introdução: a ureteroscopia flexível é uma técnica cirúrgica minimamente invasiva utilizada para o tratamento de litíase renal. A urosepse pós-operatória é uma complicação rara, mas potencialmente fatal. Os modelos tradicionais utilizados para prever o risco dessa condição apresentam precisão limitada, enquanto modelos baseados em inteligência artificial são mais promissores. O objetivo desse estudo é realizar uma revisão sistemática a respeito do uso de inteligência artificial para detecção do risco de sepse em pacientes com litíase renal submetidos à ureteroscopia flexível. Métodos: a revisão de literatura está de acordo com o Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). A busca com palavras-chave foi realizada no MEDLINE, Embase, Web of Science e Scopus e resultou no total de 2.496 artigos, dos quais 2 se enquadraram nos critérios de inclusão. Resultados: os dois estudos utilizaram modelos de inteligência artificial para predizer o risco de sepse após utereroscopia flexível. O primeiro teve uma amostra de 114 pacientes e foi baseado em parâmetros clínicos e laboratoriais. O segundo teve uma amostra inicial de 132 pacientes e foi baseado em imagens de tomografia computadorizada no pré-operatório. Ambos obtiveram boas medidas de Area Under the Curve (AUC), sensibilidade e especificidade, demonstrando boa performance. Conclusão: a inteligência artificial fornece múltiplas estratégias eficazes para estratificação do risco de sepse em pacientes submetidos a procedimentos urológicos para litíase renal, ainda que mais estudos sejam necessários.

The learning curve of bilateral laparoscopic varicocelectomy: a prospective study / A curva de aprendizado da varicocelectomia laparoscópica bilateral: um estudo prospectivo

ABSTRACT Varicocele occurs in 15% of general male population and in 35% of infertile men. Since 1992, surgical correction with laparoscopic varicocelectomy is the gold standard for treatment of symptomatic patients or patients with abnormal seminal analysis. The learning curve for this frequently performed procedure has not yet been described. In the present study, we investigated the learning curve of a single urologist in training performing his first 21 laparoscopic varicocelectomies using qualitative and quantitative tools to evaluate his performance during the process. Our results show that 14 bilateral laparoscopic varicocelectomies are enough to achieve the plateau of the learning curve.

RESUMO Varicocele ocorre em 15% dos homens e em 35% dos homens inférteis. Desde 1992, a correção cirúrgica com varicocelectomia laparoscópica é o padrão ouro para o tratamento de pacientes sintomáticos ou com análise seminal anormal. A curva de aprendizado para esse procedimento frequentemente realizado ainda não foi descrita. No presente estudo, investigamos a curva de aprendizado de um único urologista em treinamento realizando suas primeiras 21 varicocelectomias laparoscópicas usando ferramentas qualitativas e quantitativas para avaliar seu desempenho durante o processo. Nossos resultados mostram que 14 varicocelectomias laparoscópicas bilaterais são suficientes para atingir o platô da curva de aprendizado.

Bilateral inguinal transabdominal pre-peritoneal laparoscopic hernioplasty associated to bilateral laparoscopic varicocelectomy in the same intervention: a feasibility study / Hernioplastia inguinal pré-peritoneal transabdominal bilateral e varicocelectomia laparoscópica bilateral na mesma intervenção: um estudo de viabilidade

ABSTRACT Introduction: Inguinal hernia and varicocele are common conditions in male population. Laparoscopy brings the opportunity to treat them simultaneously, through the same incision. However, there are different opinions about the risks for testicular perfusion of multiple procedures in the inguinal region. In this study, we assessed the feasibility of simultaneous laparoscopic procedures by studying clinical and surgical outcomes of patients undergoing bilateral inguinal hernioplasty using the transabdominal preperitoneal (TAPP) technique with and without concomitant bilateral laparoscopic varicocelectomy (VLB). Methods: a sample of 20 patients from the University Hospital of USP-SP with indirect inguinal hernia and varicocele with indication for surgical correction was selected. Patients were randomized into two groups, 10 undergoing TAPP (Group I) and 10 undergoing simultaneous TAPP and VLB (Group II). Data regarding total operative time, complications and postoperative pain was gathered and analyzed. Results: there was no statistical difference between groups regarding total operative time and postoperative pain. Only one complication (spermatic cord hematoma) was observed in Group I and no complications were observed in Group II. Conclusions: simultaneous TAPP and VLB in was shown to be effective and safe, which provides a basis for conducting studies on larger scales.

RESUMO Introdução: hérnia inguinal e varicocele são doenças comuns na população masculina. O advento da laparoscopia traz a oportunidade de tratá-las simultaneamente, pelo mesmo acesso. Entretanto, existem divergências sobre os riscos para a perfusão testicular de múltiplos procedimentos na região inguinal. Neste estudo, avaliamos a viabilidade de procedimentos laparoscópicos simultâneos estudando resultados clínicos e cirúrgicos de pacientes submetidos à hernioplastia inguinal bilateral pela técnica transabdominal préperitoneal (TAPP) com e sem varicocelectomia laparoscópica bilateral (VLB) concomitante. Métodos: uma amostra de 20 pacientes do Hospital Universitário da USP-SP com hérnia inguinal indireta e varicocele com indicação de correção cirúrgica foi selecionada. Os pacientes foram randomizados em dois grupos, sendo 10 submetidos à TAPP (Grupo I) e 10 submetidos à TAPP e VLB simultâneas (Grupo II). O tempo operatório total, complicações e dor pós-operatória foram coletados e analisados. Resultados: não houve diferença estatística entre os grupos com relação ao tempo operatório total e à dor pós-operatória. Apenas uma complicação (hematoma do cordão espermático) foi observada no Grupo I e não foram observadas complicações no Grupo II. Conclusões: no mesmo procedimento, submeter pacientes à TAPP e à VLB no mesmo procedimento se mostrou eficaz e seguro, o que fornece embasamento para a realização de estudos em maiores escalas.

Long-lasting brain fog is related with severity clusters of symptoms in COVID-19 patients

BACKGROUND: COVID-19 patients may experience Long-lasting symptoms from weeks to even months. AIM: To evaluate long-term cognitive impairment based on the severity of symptoms of COVID-19 infection in a primary health system setting. Material and Methods: From a database of 363 patients, 83 cases aged 47 ± 15 years, (58% females) were selected from June to August 2020. In patients who survived the virus, 24 infection-related symptoms were collected to create three severity clusters (mild, moderate, and severe). The follow-up time was at least seven months. Comparing the first two clusters with the severe cluster, the existence of brain fog and risk factors (obesity, hypertension, diabetes, chronic lung disease, and hypothyroidism) were analyzed. RESULTS: Thirty-one patients (37%) had persistent symptoms lasting up to 240 days. Fifty-one patients (61%) experienced brain fog. Concentration was affected by symptom severity (odds ratio [OR] 3.63, 95% confidence interval [CI] 1.26-10.46, p = 0.02). Short- or long-term memory loss was not affected. Moreover, symptom severity was related to brain fog (OR 3.16, 95% CI 1.05-9.51, p = 0.04). Patients with persistent symptoms had a concentration impairment associated with severity patterns (OR 24.3, 95% CI 1.73-340.11, p = 0.03). Conclusions: Brain fog is associated with symptom severity in COVID-19 survivors and lasts for more than eight months.

ANTECEDENTES: Los pacientes que han tenido COVID-19 pueden experimentar síntomas persistentes que duran semanas a meses. OBJETIVO: Evaluar el deterioro cognitivo a largo plazo en función de la severidad de los síntomas de la infección por COVID-19, en un escenario de sistema primario de salud. Material y Métodos: De una base de datos de 363 pacientes se seleccionaron 83 casos de 47 ± 15 años (58% mujeres), de junio-agosto de 2020. Se recopilaron 24 síntomas relacionados con la infección, creando tres grupos (leve, moderado y severo), en pacientes que padecieron y sobreviven al virus. El tiempo de seguimiento fue de al menos siete meses. La existencia de niebla cerebral y de factores de riesgo (obesidad, hipertensión, diabetes, enfermedad pulmonar crónica e hipotiroidismo) se comparó los dos grupos de severidad más bajos con el nivel superior. RESULTADOS: Treinta y un pacientes (37%) tuvieron síntomas prolongados con una duración de hasta 240 días. Cincuenta y un pacientes (61%) mostraron niebla cerebral. El deterioro de la concentración fue afectado por la severidad (Razón de riesgo (RR) = 3,63, Intervalos de confianza (IC) 95%: 1,26-10,46, p = 0,02). La pérdida de memoria a corto o largo plazo no fue afectada. El grupo con mayor severidad se asoció a niebla cerebral (RR = 3,16, IC95%: 1,05-9,51, p = 0,04). Los portadores de síntomas prolongados tuvieron una alteración de la concentración asociado a severidad (RR: 3,16, IC95%: 1,05-9,51, p= 0,04). Conclusiones: La niebla cerebral está relacionada con la severidad de los síntomas en supervivientes de COVID-19 permaneciendo por más de ocho meses.

Abordaje quirúrgico de tumor pardo de maxilar en síndrome de Sagliker / Surgical approach of brown maxillary tumor in Sagliker syndrome

El síndrome de Sagliker es el conjunto de alteraciones craneofaciales y esqueléticas producidas por la elevación de la hormona paratiroidea y la alteración en el metabolismo del calcio, secundarios a la insuficiencia renal crónica. Consiste en una osteodistrosfia renal que se manifiesta como apariencia desfigurada del rostro, entre las más comunes, la protrusión del maxilar y de la mandíbula, la hiperplasia de los tejidos blandos del paladar, la pérdida de la anatomía nasal, la deformidad dental y de los dedos y una estatura baja. Este síndrome fue descrito por Sagliker et al. en 2004. Se ha reportado una incidencia del 0,5 % de los pacientes que se encuentran en hemodiálisis y se presenta con mayor frecuencia en el sexo femenino entre los 18 y los 39 años de. En este caso se presenta el manejo y tratamiento de un paciente con tumor pardo de maxilar con síndrome de Sagliker que acude al servicio de cirugía oral y maxilofacial del Hospital Nacional Rosales de El Salvador

Learning curve of semi-rigid ureteroscopy for small calculi: how many cases are necessary? / Curva de aprendizado em ureteroscopia semi-rígida em cálculos de pequenas dimensões: quantos casos são necessários?

ABSTRACT Introduction: semi-rigid ureteroscopy is the procedure of choice for the treatment of ureterolithiasis, but it requires a learning curve to be performed safely. Objective: To describe an estimate of the learning curve for performing semi-rigid ureterorenolithotripsy in patients with small-sized ureterolithiasis and to estimate the minimum number of procedures necessary to safely perform the surgical procedure. Methods: this is a prospective study evaluating the learning curve of a resident of urology in the first 60 semirigid ureteroscopies in patients with ureterolithiasis up to 1cm. The patients were divided into three groups: Group I one to twenty surgeries, Group II twenty one to forty surgeries and Group III forty one to sixty surgeries. The surgeries were recorded and analyzed by two urologists experienced in endourology. A qualitative analysis was performed based on a previously validated tool and a quantitative analysis. Results: all qualitative variables had significant variation between Groups I and II (p<0.001), and between Groups I and III (p<0.001). There was a difference in time to access the ureter, passage of a double J catheter and total operative time between Groups I and II (p<0.001) and Groups I and III (p<0.001). Conclusion: after 40 cases there seems to be little increase in both quantitative as well as qualitative evaluation in surgical performance for performing semi-rigid ureterolithotripsy safely in calculations up to 1cm.

RESUMO Introdução: ureteroscopia semi-rígida é o procedimento de escolha para o tratamento da ureterolitíase, mas necessita de uma curva de aprendizado para ser executada com segurança. Objetivo: descrever uma estimativa da curva de aprendizado para realização da ureterorrenolitotripsia semi-rígida em pacientes com ureterolitíase de pequena dimensão e estimar o número mínimo de procedimentos necessários para realizar o procedimento cirúrgico com segurança. Métodos: trata-se de um estudo prospectivo avaliando a curva de aprendizado de um residente de urologia nas primeiras 60 ureteroscopias semi-rígidas em pacientes com ureterolitíase até 1cm. Os pacientes foram divididos em três grupos: Grupo I uma a vinte cirurgias, Grupo II vinte e uma a quarenta cirurgias e Grupo III quarenta e uma a sessenta cirurgias. As cirurgias foram gravadas e analisadas por dois urologistas experientes em endourologia. Foi feita uma análise qualitativa baseada em uma ferramenta previamente validada e uma análise quantitativa. Resultados: todas as variáveis qualitativas tiveram variação significativa entre os Grupos I e II (p<0.001), e entre os Grupos I e III (p<0.001). Houve diferença no tempo para acesso ao ureter, passagem de cateter duplo J e tempo operatório total entre os Grupos I e II (p<0.001) e nos Grupos I e III (p<0.001). Conclusão: após 40 casos parece haver pouco incremento tanto na avaliação quantitativa bem como na avaliação qualitativa em performance cirúrgica para a realização de ureterolitotripsia semi-rígida com segurança em cálculos de até 1cm.
