Personalized Mobile Health-Enhanced Cognitive Behavioral Intervention for Maternal Distress: Examining the Moderating Role of Adverse Childhood Experiences.

BACKGROUND: Maternal history of trauma is a risk factor for distress during pregnancy. The purpose of this paper was to examine the theorized differential impact of a cognitive behavioral intervention (Mothers and Babies Personalized; MB-P) on maternal distress and emotional regulation for those with ≥ 1 adverse childhood experiences (ACEs; vs no ACEs) from pregnancy to 3 months postpartum. METHODS: Between August 2019 and August 2021, eligible pregnant individuals aged ≥ 18 years, < 22 weeks' gestation, and English-speaking were recruited from 6 university-affiliated prenatal clinics. Participants (N = 100) were randomized to MB-P (n = 49) or control (n = 51). Analyzable data were collected for 95 participants. Analyses tested progression of change (slope) and at individual timepoints (panel analysis) for perinatal mental health outcomes. RESULTS: The majority of participants (n = 68, 71%) reported experiencing > 1 ACE (median = 1, range: 0-11). Participants demonstrated significant differential effects for depressive symptoms in absence of ACEs (standardized mean differences [SMD] = 0.82; 95% confidence interval [CI] = [0.13-1.51]) vs in presence of ACEs (SMD = 0.39; 95% CI = [-0.20 to 0.97]) and perceived stress in absence of ACEs (SMD = 0.92; 95% CI = [0.23-1.62]) vs in presence of ACEs (SMD = -0.05; 95% CI = [-0.63 to 0.53]). A panel analysis showed significantly reduced depressive symptoms postintervention and increased negative mood regulation at 3 months postpartum for individuals with ACEs. CONCLUSIONS: Findings support effectiveness of the MB-P intervention to reduce prenatal distress for all pregnant individuals. Preliminary exploration suggests the possibility that individuals with ACEs may benefit from enhanced trauma-informed content to optimize the effects of a perinatal intervention.

The psychophysiology of Mastermind: Characterizing response times and blinking in a high-stakes television game show.

Television game shows have proven to be a valuable resource for studying human behavior under conditions of high stress and high stakes. However, previous work has focused mostly on choices-ignoring much of the rich visual information that is available on screen. Here, we take a first step to extracting more of this information by investigating the response times and blinking of contestants in the BBC show Mastermind. In Mastermind, contestants answer rapid-fire quiz questions while a camera slowly zooms in on their faces. By labeling contestants' behavior and blinks from 25 episodes, we asked how accuracy, response times, and blinking varied over the course of the game. For accuracy and response times, we tested whether contestants responded more accurately and more slowly after an error-exhibiting the "post-error increase in accuracy" and "post-error slowing" which has been repeatedly observed in the lab. For blinking, we tested whether blink rates varied according to the cognitive demands of the game-decreasing during periods of cognitive load, such as when pondering a response, and increasing at event boundaries in the task, such as the start of a question. In contrast to the lab, evidence for post-error changes in accuracy and response time was weak, with only marginal effects observed. In line with the lab, blinking varied over the course of the game much as we predicted. Overall, our findings demonstrate the potential of extracting dynamic signals from game shows to study the psychophysiology of behavior in the real world.

Impact of detrusor underactivity on the postoperative outcomes after benign prostatic enlargement surgery.

INTRODUCTION AND OBJECTIVE: Previous studies suggest that men with detrusor underactivity (DUA) have less symptomatic improvement after prostate surgery than those with normal contractility, but the available data is controversial. We aim to determine the differences in functional outcomes of patients with or without DUA who underwent photovaporization of the prostate (PVP) with GreenLight™180 W XPS. METHODS: A cohort of patients with lower urinary tract symptoms (LUTS) who underwent PVP between 2012 and 2019 was evaluated. Patients were stratified according to bladder contractility index (BCI). DUA was defined as BCI < 100. Those with normal contractility (BCI = 100-150) were included in Group 1, and those with DUA (BCI < 100) in Group 2. Primary outcomes were symptomatic improvement defined as a reduction ≥ 4 points in the international prostate symptom score (IPSS) and a reduction of at least 1 point in the quality of life (IPSS-QoL). Complications according to the Clavien-Dindo classification were also recorded. RESULTS: A total of 271 patients who underwent PVP with GreenLight™ and met the inclusion criteria were assessed. Group 1 included 158 patients, while Group 2 included 113 patients. Mean follow-up was 24 months. Patients with normal contractility had a median reduction of 11 points (18.9 ± 8.0 to 7.1 ± 7.0) while patients with DUA had a median reduction of 10 points (19.3 ± 6.9 to 8.6 ± 8.4) in IPSS score; these differences were not statistically significant (p = .20). Patients in Group 1 had a 1.92 higher chance of QoL improvement (OR, 1.92; 90% CI, 1.10-3.37), compared to those in Group 2. Failure to void after PVP was most frequently reported in DUA patients (OR, 2.36; 90% CI, 1.26-4.43). Sociodemographic characteristics, intraoperative complications, conversion rates, hospital stay, and urinary catheterization time were similar between groups. CONCLUSIONS: Patients with LUTS, regardless of their BCI, improved their symptoms after PVP according to the IPSS. However, patients with DUA were more likely not to improve their QoL after the procedure and had a higher chance of failure to void in the immediate postoperative period. An appropriate counseling process with the patient discussing possible outcomes based on these findings should be encouraged.

Present value of the Urethral mobility test as a tool to assess Stress urinary incontinence due to Intrinsic sphincteric deficiency.

Q-tip test offers a simple approach for identifying urethral hypermobility. Considering surgical treatment, stress urinary incontinence (SUI) must be classified and the contribution of intrinsic sphincter deficiency (ISD) and/or urethral hypermobility must be determine. We believe there's a correlation between abdominal leak point pressure (ALPP) and urethral mobility degree, and the aim of this study is to explore it using Q-tip. We conducted a prospective study, between years 2014 and 2016. Females over 18 years presenting with signs and symptoms of SUI according to the 2002 ICS Standardization of Terminology were included. Assessment was made with the International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF), the Q-tip test and invasive urodynamics. Urethral mobility (UM) and ALPP were analyzed. We built two composite variables based on reported risk factors for ISD, defined as composite variable A (equal to a Q-tip test < 30° AND ICIQ-SF ≥ 10 points) and composite variable B (equal to low urethral mobility AND/OR hypoestrogenism AND/OR history of radiotherapy AND/OR previous pelvic surgery). Correlation analyzes were made according to the type of variable. A total of 221 patients were included. Incontinence was rated as moderate and severe by 65.3% and 6.8%, respectively. The analysis showed a 61.75%, 51.61% and 70.6% agreement between ALPP and UM, ALPP and composite variable A and ALPP and composite variable B respectively. Correlation and concordances were low (r = 0.155, r_s = - 0.053 and r_s = - 0.008), (rho_c = 0.036, k = 0.116 and k = 0.016). Neither the degree of UM, nor the composite variables, correlate or agree with urethral function tests in UDS, suggesting that the ALPP cannot be predicted using the Q-tip test or the ICIQ-SF for classifying patients with SUI.

Prognostic Factors for Inguinal Lymph Node Involvement and Tumor Recurrence in Squamous Cell Carcinoma of the Penis / Factores pronósticos de compromiso ganglionar inguinal y recaída tumoral en carcinoma escamocelular de pene

Zoom Image Abstract Introduction Penile carcinoma is an aggressive disease with catastrophic consequences that frequently lead to death. Therefore, further knowledge on the prognostic factors that can help identify patients in need of more aggressive treatments becomes essential. Objective To identify the prognostic factors for lymph node (LN) involvement and tumor recurrence in patients diagnosed with squamous cell carcinoma of the penis (SCCP). Methods A retrospective cohort study was conducted. Patients diagnosed and treated for SCCP at Instituto Nacional de Cancerología between 2008 and 2015 were included in the sample. Cases in which no information on recurrence was available for the follow-up were excluded, as well as patients with no initial pathology and those getting penile reconstructions after cancer. Relevant data was retrieved from the medical records of each patient, and a descriptive analysis was performed. Subsequently, this data was used to apply a logistic regression model to determine the potential clinical and histopathological prognostic factors. Results A total of 104 patients were included in the present study. The average age of the sample was 59 years, while the follow-up averaged 24 months per patient. Inguinal lymphadenectomy was performed on 61 patients (59%) during the follow-up. The logistic regression model showed that lymphovascular invasion (odds ratio [OR]: 6.7; 95% confidence interval [95%CI]: 1.2­35) and poor tumor differentiation (OR: 17; 95%CI: 3.2­92) were associated with tumor recurrence. Likewise, the lymphadenectomy procedures showed that lymphovascular invasion was associated with LN involvement (OR: 3.3; 95%CI: 1.1­10). Conclusion Lymphovascular invasion was the strongest prognostic factor observed in our sample, aiding in the prediction of inguinal LN involvement and tumor recurrence in SCCP patients

Introduccion El cáncer de pene es una enfermedad agresiva con consecuencias catastróficas que frecuentemente llevan a la muerte. Por lo tanto, es esencial un mayor conocimiento sobre los factores pronósticos que pueden ayudar a identificar a los pacientes que necesitan tratamientos más agresivos. Objetivo Identificar los factores pronósticos patológicos de compromiso ganglionar inguinal y recaída tumoral en pacientes con carcinoma escamocelular de pene. Métodos Se realizó un estudio de cohorte retrospectivo. Se incluyeron en la muestra pacientes diagnosticados y tratados por carcinoma escamocelular de pene (SCCP) en el Instituto Nacional de Cancerología entre 2008 y 2015. Los casos en los que no había información sobre la recurrencia en el seguimiento fueron excluidos, así como los pacientes sin patología inicial y aquellos que reciben reconstrucciones del pene después del cáncer. Se recuperaron los datos relevantes de los registros médicos de cada paciente, y una descripción fue realizada. Posteriormente, estos datos se utilizaron para aplicar un modelo de regresión logística para determinar los posibles factores pronósticos clínicos e histopatológicos. Resultados Un total de 104 pacientes fueron incluidos en el estudio. La edad promedio de la muestra fue de 59 años, mientras que el seguimiento promedió fue de 24 meses por paciente. La linfadenectomía inguinal se realizó en 61 pacientes (59%) durante el seguimiento. El modelo de regresión logística mostró que la invasión linfovascular (odds ratio [OR]: 6,7; intervalo de confianza del 95% [IC 95%]: 1,2­35) y la pobre diferenciación tumoral (OR: 17; IC 95%: 3,2­92) se asociaron con recurrencia tumoral. Así mismo, los procedimientos de linfadenectomía mostraron que la invasión linfovascular se asoció con afectación de LN. (OR: 3,3; IC 95%: 1,1-10). Conclusión La invasión linfovascular es el factor pronóstico independiente más importante que se asocia de manera independiente con compromiso ganglionar inguinal positivo y recaída tumoral.

Photovaporization of the prostate with GreenLight™ laser 180 W XPS versus transurethral resection of the prostate with monopolar energy for the treatment of benign prostatic enlargement: a cost-utility analysis from a healthcare perspective.

PURPOSE: To assess the cost-utility of the photovaporization of the prostate (PVP) with GreenLight™ laser 180 W XPS compared to transurethral resection of the prostate with monopolar energy (M-TURP) for lower urinary tract symptoms (LUTS) due to benign prostatic enlargement (BPE) from a healthcare perspective in Colombia. METHODS: We designed a Markov model to compare four health states following treatment with either PVP or M-TURP to estimate expected costs and outcomes. We used the results of the only randomized clinical trial published to date comparing PVP versus M-TURP to estimate surgical outcomes, complications, re-operation and re-intervention rates. Time horizon was defined at 2 years with four cycles of 6 months each. Resource-use estimation involved a random selection of clinical records from a local institution and cost list from public healthcare system. Costs were obtained in Colombian pesos and converted to US dollars. Threshold was defined at three-times the Colombian gross domestic product (GDP) per capita. Quality-adjusted-life-years (QALYs) were used based on the utilities of the available literature. Uncertainty was analyzed with deterministic and probabilistic models using a Monte Carlo simulation. RESULTS: Patients who underwent PVP gained 1.81 QALYs compared to 1.59 with M-TURP. Costs were US$6797.98 and US$7777.59 for M-TURP and PVP, respectively. Incremental cost-effectiveness ratio was US$4452.81 per QALY, favoring PVP as a cost-effective alternative in our context. CONCLUSIONS: In Colombia, with current prices, PVP is cost-effective when compared to M-TURP for LUTS due to BPE for a 2-year time horizon.

Prevalence of lower urinary tract symptoms and overactive bladder in men and women over 18 years old: The Colombian overactive bladder and lower urinary tract symptoms (COBaLT) study.

AIMS: To estimate the prevalence of LUTS and overactive bladder (OAB) in the Colombian population. METHODS: A cross-sectional, population-based study was conducted in men and women ≥18 years using directed interviews and self-administered questionnaires in five main cities in Colombia. A sample size of 1054 subjects was estimated (prevalence of LUTS/OAB 15%, CI 95%, statistical power 80%, precision 3%). We used a multi-stage probabilistic sampling technique to randomly select individuals in the community, stratified by socioeconomic status, gender, and age. We used the 2002 ICS and 2010 IUGA/ICS definitions as well as validated questionnaires in Spanish. Descriptive statistics were employed. RESULTS: A total of 1060 participants were included. Mean age was 42 (range 18-89) years. The prevalence of at least one LUTS was 84%, while overactive bladder was reported by 31.8% participants. Among individuals with at least one LUTS, 13.2% would feel "mostly unsatisfied," "unhappy," or "terrible" to spend the rest of their lives with their current urinary condition. Nocturia was the most prevalent LUTS (55.3%), followed by urgency (46.4%) and frequency (45.8%). Urge, stress, and mixed urinary incontinence were reported by 15.3%, 8.6%, and 7% of participants, respectively. CONCLUSIONS: LUTS are highly prevalent in the Colombian population and severely affect quality of life. This is the first study conducted in Colombia and Latin America focused on evaluating LUTS in men and women of all age groups of interest using a multi-stage probabilistic sampling technique. These results may have a significant influence on health decision-making and assessment of future therapies.

Mesotelioma de túnica vaginal en paciente con hidrocele rápidamente progresivo / Mesothelioma of the Tunica Vaginalis in a Patient with Rapidly Progressive Hydrocele

El mesotelioma es una entidad poco común y agresiva que compromete el mesotelio, involucrando así los diferentes órganos cubiertos por membranas serosas. El mesotelioma de túnica vaginal es una neoplasia muy rara, con un cuadro clínico poco específico y de difícil diagnóstico con las técnicas imagenológicas actuales. Presentamos el caso de un paciente con hidrocele rápidamente progresivo que fue llevado a hidrocelectomía. Se realizó un diagnóstico histopatológico de mesotelioma epitelial maligno de túnica vaginal que requirió orquidectomía radical, hemiescrotomectomía y linfadenectomía retroperitoneal. A un año de seguimiento, el paciente no tiene evidencia de la enfermedad.

Mesothelioma is an uncommon and aggressive entity that compromises the mesothelium, thus involving the different organs covered by serous membranes. The mesothelioma of the tunica vaginalis is a very rare neoplasm, with a non-specific clinical picture and difficult diagnosis with current imaging techniques. We report the case of a patient with rapidly progressive hydrocele who was taken to hydrocelectomy. A histopathological diagnosis of epithelial mesothelioma of the tunica vaginalis was made, which required radical orchiectomy, hemiscrotectomy and retroperitoneal lymphadenectomy. At one year of follow-up, the patient has no evidence of the disease.

Effectiveness of the Remeex system™ in Colombian women with recurrent stress urinary incontinence or intrinsic sphincter deficiency.

INTRODUCTION AND HYPOTHESIS: We report our experience with the Remeex system™ in women with recurrent stress urinary incontinence (SUI) or intrinsic sphincter deficiency (ISD). METHODS: A multicenter retrospective study was conducted in women who underwent an adjustable sling procedure between 2011 and 2016. We used urodynamic studies (UDS) preoperatively and the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) and cough stress test (CST) pre- and postoperatively. Primary outcomes were subjective (no leakage reported by the patient) and objective (no leakage during CST) cure and improvement rates (reduction of ≥4 points in ICIQ-SF). Descriptive and inferential statistics were employed. RESULTS: A total of 50 patients were included. Mean age was 62 years (SD ± 11.35). Median follow-up was 19.5 months [interquartile range (IQR) 12.95-41.38]. Urinary incontinence (UI) was described as moderate and severe by 8 (16%) and 42 (84%) patients, respectively, and 25 (50%) had stress-predominant mixed urinary incontinence (MUI). Objective and subjective cure rates were 90% and 48%, respectively, while 82% of patients achieved improvement. Impact of UI on quality of life (QoL) improved from 10 (IQR 9-10) to 2 (IQR 0-5) (p < 0.0001). Clavien-Dindo II complications occurred in 14 (28%) patients, and one (2%) had IIIa. Tape erosion occurred in one (2%) patient, and five (10%) required readjustments. Logistic regression identified MUI [odds ratio (OR) 3.3, 95% confidence interval (CI) 1.02-10.89] and vaginal atrophy (OR 4.2, 95% CI 1.06-16.03) as predictors of low subjective cure rate. CONCLUSIONS: Adjustable slings represent a valuable and safe option in the management of recurrent SUI or ISD, with improvement in QoL. Results should be carefully interpreted due to our small sample and retrospective design.

[Efficacy of lycopene intake in primary prevention of prostate cancer: a systematic review of the literature and meta-analysis.] / Eficacia del consumo de licopenos en la prevenciín primaria de cáncer de próstata: una revisión sistemática de la literatura y meta­análisis.

OBJECTIVE: To evaluate the efficacy of lycopene intake in primary prevention of prostate cancer (PCa). METHODS: A systematic search of the literature was conducted in March 2015 and the articles published between the years 1990-2015 were reviewed. The following search terms were used: prostate cancer, prostatic neoplasm, lycopene, prevention, effectiveness and efficacy (MeSH). Publications including research in humans, written in English and whose texts were accessible were reviewed. The types of studies included were: clinical trials, cohort and case-control studies. We found 343 articles; of these, 27 were included in the systematic review. After the latter were rigorously analyzed, 23 were included in the meta-analysis using the pooled odds ratios (OR) and risk ratios (RR) of case-control and cohort studies, respectively, and their confidence intervals (95% CI), using random-effects models with Review Manager 5.2. RESULTS: Out of the 27 articles included in the systematic review, 22 were case-control and 5 were cohort studies. For the case-control studies, the total number of patients with PCa was 13,999 and the total number of controls 22,028. Cohort studies included 187,417 patients and PCa was diagnosed in 8,619 of these. The metaanalysis determined an OR = 0.94 (IC 95% 0.89-1.00) and RR = 0.9 (IC 95% 0.85-0.95) of PCa related with lycopene and/or raw or cooked tomatoes intake. CONCLUSIONS: Although our study found that there is a statistically significant inverse association between lycopene intake and PCa, the magnitude of this association is weak and comes solely from observational studies, which do not allow recommending its use as a standard of practice. High-quality randomized clinical trials are required to clarify current evidence.

Urological approach for cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in a clinical care center.

BACKGROUND: Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) is associated with significant manipulation of the urinary tract (UT). We aim to describe the urological events and their management in patients who underwent CRS-HIPEC. METHODS: Clinical records of patients who underwent treatment between 2007 and 2015 were reviewed. Urological events and their multidisciplinary management were analyzed. Descriptive statistics were calculated. RESULTS: A total of 103 patients were included. Mean age was 51 years (SD ± 11.8). Mean peritoneal cancer index (PCI) was 20.4 (SD ± 10.1). Primary tumors included appendicular (64%), gynecological (16%), colorectal (10%), and peritoneal mesotheliomas (9%). Ninety-three percent of patients had bilateral ureteral catheters inserted prior to surgery, without complications. Intraoperative UT injuries occurred in 7% of patients. In 5% of patients, tumor invasion of the bladder was evident at surgery and partial resection and primary repair of the bladder wall was performed. Urological complications included urinary tract infection (UTI) (21%) acute post-renal failure (4%), urinary fistulae (4%), and acute urinary retention (AUR) (1%). CONCLUSIONS: In our study, intraoperative UT events and postoperative complications, although not neglectable, were infrequent. Due to the high complexity of these cases, a multidisciplinary approach is mandatory. However, randomized clinical trials are necessary to clarify current data on the need and efficacy of prophylactic ureteral catheterization in patients undergoing CRS-HIPEC.

Trends in pelvic organ prolapse management in Latin America.

AIMS: To describe practice patterns and perspectives regarding pelvic organ prolapse (POP) management among urologists, gynecologists, and urogynecologists in Latin America (LATAM). METHODS: A cross-sectional study was conducted from April to September 2016 using a 37-item internet-based survey applied to members of urologic and gynecologic associations from 18 countries. Participants were asked about their background and practice patterns. Descriptive statistics were employed. RESULTS: A total of 673 responses were obtained. Most came from Colombia (33.6%) and Brazil (24.7%). The number of practitioners who perform at least one POP procedure per month and were eligible to finish the survey was 529 (78.6%), out of which 323 (61.0%) were urologists, 156 (29.5%) gynecologists, and 50 (9.5%) urogynecologists. Mesh-based POP repairs were used by 57.1% of participants. Out of non-mesh users, the most frequent vaginal procedures were sacrospinous fixation (30%), colporrhaphy (25%), and uterosacral fixation (12%). Regarding the impact of FDA warnings, 75.2% participants indicated that the use of mesh has declined, and 41.9% considered this has had a negative effect in the use of incontinence tapes as well. Only two physicians reported legal disputes related to mesh procedures, and 75.8% said they would still indicate mesh repairs in certain cases. CONCLUSIONS: This is the first report on POP practice patterns in LATAM. Preferences regarding surgical management of POP are not very different from international trends. Despite intense scrutiny and media exposure, mesh-based procedures are still largely used in LATAM.

Histological Findings in Very Low Risk Prostate Cancer Patients Managed with Radical Prostatectomy / Hallazgos histopatológicos en pacientes con cáncer de próstata con criterios de muy bajo riesgo llevados a prostatectomía radical

Objectives: lo describe the histológica] findings in patients with prostate cáncer (PCa) dmically dassifíed as very low risk who underwent treatment with radical prostatectomy (RP). Material and methods: A retrospective observational study was conducted. Clinical records of patients who underwent RP between 2007'2015 who met Epstein criteria for very low risk disease were reviewed. Histológica! diagnosis was described and analyzed to determine ¿f such criteria predicted very low risk. Results: A total of 609 records were reviewed; 83 (13.6%) met Epstein's criteria. Mean age was 59 (SD±7) years and median PSA at diagnosis was 5.4 ng'dl (IQR 4.3 ­ 6.8). Pathology showed a median tumor volume of 4% (IQR 1 ­ 10%). Gleason score was 3+3 in 55 (66.3%) cases, but 28 (33.7%) were redassified to a greater score. Two (2.4%) patients were redassified as pT3a, 80 (96.4%) as pT2 and 1 (1.2%) was found to be pTO. In those subjected to pelvic lymphadenectomy (42.2%) no positive lymph nodes were found. Conclusions: Up to one-third of the patients dinically classmed with very low risk PCa had a greater Gleason score. Only 3% had locally advanced tumors, which is comparable to previous studies. Epstein's criteria seem to be adequate in predicting organ-conñned disease.

Objetivo: Describir los hallazgos de la patología definitiva de los pacientes inicialmente clasificados con tumores de muy bajo riesgo que fueron llevados a prostatectomía radical (PR). Materiales y métodos: Estudio observacional retrospectivo. Se revisaron las historias clínicas de pacientes llevados a PR entre enero de 2007 y diciembre de 2015. Se describieron y analizaron los hallazgos histopatológicos posquirúrgicos, con el objetivo de determinar si cumplir con dichos criterios eran predictores de enfermedad órgano'confinada y de bajo riesgo. Resultados: Se revisaron 609 historias clínicas de pacientes llevados a PR, de las cuales 53 (13,6%) casos cumplían con criterios de muy bajo riesgo. La media de edad de estos pacientes fue de 59 (DE ± 7) años y la mediana de PSA al diagnóstico fue de 5,4 (RIQ 4,3'6,8) ng'dl. En la patología definitiva, la mediana del volumen tumoral fue del 4% (RIQ: 1'10%). El puntaje de Gleason fue de 3 + 3 en 55 (66,3%) pacientes, mientras que 28 (33,7 %) fueron reclasificados a uno mayor Solo 2 (2,4%) pacientes se reclasificaron como pT3a, 80 (96,4 %) pacientes fueron clasificados como pT2 y un (1,2 %) paciente fue reclasificado como pTO. No se evidenció compromiso ganglionar en ninguno de los pacientes llevados a linfadenectomía. Conclusión: Los hallazgos demuestran que hasta una tercera parte de los pacientes con tumores inicialmente clasificados como de muy bajo riesgo tienen puntajes de Gleason mayor en la patología definitiva; sin embargo, solo el 3 % tienen tumores localmente avanzados, lo cual es consistente con lo reportado en la literatura mundial. Los criterios de Epstein son adecuados para predecir la presencia de tumores órgano-confinados.

Impact of Rectal Swabs on Infectious Complications after Transrectal Prostate Biopsy.

OBJECTIVES: To determine the impact of rectal swabs (RSs) on infectious complications (IC) following prostate biopsy (PB). METHODS: A retrospective cohort study was conducted including all patients subjected to PB between 2009 and 2013. Group B consisted of patients with a RS and group A of patients without. RS reported the presence of gram-positive or negative germs, sensitive or resistant to ciprofloxacin. Antimicrobial prophylaxis was adjusted to the result. Frequency of IC in each group was determined. RESULTS: Group B had 548 (47.20%) patients and group A 613 (52.80%). From group B, 250 (45.62%) of the RSs showed fluoroquinolone (FQ)-resistant germs. Forty nine (16.44%) patients with sensitive germs vs. 147 (59.51%) with resistant germs had a history of previous FQ treatment (p < 0.0001). IC were observed in 33 (5.49%) patients from group A and in 7 (1.28%) patients from group B (p < 0.0001), requiring hospitalization in 4.99 vs. 1.28%, respectively. IC and hospital admissions were reduced in 76.68 and 74.34%, respectively, following the implementation of RS. CONCLUSIONS: RS and targeted antibiotic prophylaxis prior to PB was associated with a significant reduction in IC and hospital admissions. Ceftriaxone could be an alternative in cases of known resistance. Past history of FQ treatment is associated with increased resistance.

Advantage of urine based molecular diagnosis of Zika virus.

Zika virus (ZIKV) infection is an emerging global health concern, and diagnostic recommendations are currently developing based on new information. Several case or small sample size studies using both urine and blood samples suggest that ZIKV RNA can be detected at higher levels and for a longer time after onset of infection in urine compared to blood. We recommend that urine and serum collection for molecular testing be a standard part of evaluating patients for ZIKV infection, and that urine is a good alternative testing sample when blood collection is problematic.
