Acute kidney injury (AKI) consists of a rapid renal function decline which usually increases serum urea and creatinine levels. Since kidney injury begins by inducing biological and molecular changes which evolve to cellular damage, biomarkers could be used as tools for monitoring early AKI appearance, and predicting its recovery. Among the main AKI biomarkers the neutrophil gelatinase-associated lipocalin, cystatin C, kidney injury molecule-1, monocyte chemotactic peptide-1, N-acetyl-β-D-glucosaminidase, interleukin-18, liver-type fatty acid-binding protein, netrin-1, cycle arrest markers, endogenous ouabain, selenium-binding protein 1, and BPIFA2 marker, have been described. Even though novel biomarkers seem to be more helpful to early detect AKI and/or predict the need for renal replacement, and mortality compared to serum creatinine, more comprehensive studies are still required to determine their clinical utility.
Background: Literature is scarce regarding the influence of psychological readiness on return to sports after shoulder instability surgery. Purpose: To evaluate the predictive ability of the Shoulder Instability–Return to Sport after Injury (SIRSI) score in measuring the effect of psychological readiness on return to sports and to compare it between athletes who returned to sports and athletes who did not return to sports. Study Design: Cohort study; Level of evidence, 2. Methods: A prospective analysis was performed of patients who underwent an arthroscopic Bankart repair or a Latarjet procedure between January 2019 and September 2020. Psychological readiness to return to play was evaluated using the SIRSI instrument. Preoperative and postoperative functional outcomes were measured by the Rowe, Athletic Shoulder Outcome Scoring System, and Western Ontario Shoulder Instability Index scores. The predictive validity of the SIRSI was assessed by the use of receiver operating characteristic (ROC) curve statistics. The Youden index was calculated and used to determine a SIRSI score cutoff point that best discriminated psychological readiness to return to sports. A logistic regression analysis was performed to evaluate the effect of psychological readiness on return to sports and return to preinjury sports level. Results: A total of 104 patients were included in this study. Overall, 79% returned to sports. The SIRSI had excellent predictive ability for return-to-sport outcomes (return to sports: area under ROC curve, 0.87 [95% CI, 0.80-0.93]; return to preinjury sports level: area under ROC curve, 0.96; [95% CI, 0.8-0.9]). A cutoff level of ≥55 was used to determine whether an athlete was psychologically ready to return to sports and to return to preinjury sports level (Youden index, 0.7 and 0.9, respectively). Of those who returned to sports, 76.8% were psychologically ready to return to play, with a median SIRSI score of 65 (interquartile range, 57-80). In comparison, in the group that did not return to sports, only 4.5% achieved psychological readiness with a median SIRSI score of 38.5 (interquartile range, 35-41) ( P < .001). Regression analysis for the effect of SIRSI score on return to sports was performed. For every 10-point increase in the SIRSI score, the odds of returning to sports increased by 2.9 times. Moreover, those who did not achieve their preinjury sports level showed poorer psychological readiness to return to play and SIRSI score results. Conclusion: The SIRSI was a useful tool for predicting whether patients were psychologically ready to return to sports after glenohumeral stabilization surgery. Patients who returned to sports and those who returned to their preinjury sports level were significantly more psychologically ready than those who did not return. Therefore, we believe that the SIRSI score should be considered along with other criteria that are used to decide whether the patient is ready to return to sports.
Background: There is a great discrepancy between the rates of recurrent instability reported after arthroscopic Bankart repair in relation to the follow-up time. Purpose: To analyze the rate of recurrences after arthroscopic Bankart repair in the long term, emphasizing whether a minimum follow-up of 2 years is adequate to assess this outcome. Study Design: Case series; Level of evidence, 4. Methods: Between January 2008 and April 2013, a total of 356 athletes underwent arthroscopic Bankart repair for anterior glenohumeral instability at our institution. Return to sports, the Rowe score, the Subjective Shoulder Value (SSV), and the Athletic Shoulder Outcome Scoring System (ASOSS) were used to assess functional outcomes. We analyzed the proportion of recurrences before and after 4 years of follow-up. Additionally, we performed a Kaplan-Meier analysis to evaluate recurrence-free time in patients with a recurrence. Results: The mean follow-up was 10.5 ± 1.6 years, and the mean age was 20.8 ± 3.9 years. In total, 90% of patients were able to return to sports; of these, 91% returned to their preinjury level of play. The Rowe, SSV, and ASOSS scores showed a statistical improvement after surgery ( P < .01). The proportion of patients with a recurrence during the follow-up period was 25% (95% CI, 20%-31%; n = 70), and the mean time until a recurrence was 3.8 ± 2.6 years. Only 39% of the recurrences (95% CI, 30%-48%) occurred in the first 2 years after surgery, while 61% (95% CI, 50%-73%) occurred in the first 4 years after surgery. Conclusion: In our study, the effectiveness of Bankart repair to stabilize the shoulder decreased significantly over time. Indeed, less than half of the recurrences occurred after 2 years of follow-up. Therefore, we propose that the recommended minimum follow-up should be 4 years; otherwise, it is very likely that the actual rate of recurrences will be significantly underestimated.
ObjectivesTo assess the effectiveness and safety of risperidone and aripiprazole in children with autism spectrum disorder (ASD).Design and settingOverview of systematic reviews (SRs).Search methodsIn October 2021, we searched Cochrane Central Register of Controlled Trials, MEDLINE, Embase, PsycInfo and Epistemonikos placing no restrictions on language or date of publication.ParticipantsChildren aged 12 years or less with ASD.InterventionsRisperidone and aripiprazole with no dosage restrictions.Data collection and analysisWe rated the methodological quality of the included SRs using A Measurement Tool to Assess Systematic Reviews (AMSTAR 2). We reported the Grading of Recommendations, Assessment, Development and Evaluation certainty of the evidence according to the analysis conducted by the authors of the included SRs.Main outcomes measuredA multidisciplinary group of experts agreed on analysing nine critical outcomes evolving core and non-core ASD symptoms.Patient and public involvementOrganisations of parents of children with ASD were involved during part of the process, participating in external revision of the final version of the report for the Chilean Ministry of Health with no additional comments (ID 757-22-L120 DIPRECE, Ministry of Health, Chile). The organisations involved were: Fundación Unión Autismo y Neurodiversidad, Federación Nacional de Autismo, Vocería Autismo del Sur, and Vocería Autismo del Norte.ResultsWe identified 22 SRs within the scope of this overview, of which 16 were of critically low confidence according to AMSTAR 2 and were excluded from the analysis. Both aripiprazole and risperidone were effective for reducing autism symptoms severity, repetitive behaviours, inappropriate language, social withdrawal and behavioural problems compared with placebo. The certainty of the evidence for most outcomes was moderate. Risperidone and aripiprazole are associated with metabolic and neurological adverse events. Follow-up was short termed.ConclusionsWe found that aripiprazole and risperidone probably reduce symptom severity at short-term follow-up but may also cause adverse events. High-quality and updated SRs and larger randomised controlled trials with longer term follow-up are needed on this topic.Overview protocolPROSPERO CRD42020206535.
Este artículo se enfoca en el paciente con una recuperación prolongada tratado ambulatoriamente. Fue realizado mediante una revisión narrativa de la evidencia (búsquedas en Pubmed y el uso de revisiones sistemáticas vivas) y la consulta a pacientes con síntomas persistentes. Definición de COVID-19 postagudoEl COVID-19 postagudo o prolongado es una enfermedad multisistémica que procede al cuadro agudo leve. Se lo define como el cuadro que se extiende más allá de las tres semanas desde el inicio de los primeros síntomas y hasta 12 semanas, plazo luego del cual se lo denomina COVID-19 crónico. ¿Qué tan común es este síndrome?En el Reino Unido se estimó que el 10 % de los pacientes permanecen sintomáticos por más de tres semanas. Este porcentaje es inferior al citado en otros estudios con presentaciones iniciales más graves de la enfermedad. En los EE.UU. se informó que el 65 % de los pacientes se recuperaba tras 14 a 21 días de una prueba de detección de SARS-CoV-2 positiva.
Purpose To assess the effects of Serenoa repens alone or in combination with other phytotherapy compared to placebo in men with LUTS due to benign prostatic enlargement. Materials and Methods Following a registered protocol (CRD42021226655), we searched (December 2020) MEDLINE, CENTRAL, Embase, ClinicalTrials.gov, WHO-ICTRP trials platform and other sources with no restrictions on language, publication date or status. We included randomized controlled trials, and we critically appraised them using the Cochrane Tool for Risk of Bias Assessment (RoB 2). We conducted random-effects meta-analysis when appropriate. The primary outcomes included urinary symptoms score, quality of life, and adverse events. The certainty of the evidence was rated using GRADE. Results We included 27 trials with 4,853 participants. S. repens results in little to no difference in urinary symptoms, quality of life, and adverse events at short- and long-term follow-up. S. repens combined with other phytotherapy may slightly reduce urinary symptoms at short-term follow-up, but the results are uncertain. The results on quality of life and adverse events are also very uncertain. Conclusions S. repens alone may result in no clinical benefits for men with LUTS. There is greater uncertainty in the effects of S. repens in combination with other phytotherapy.
Introducción: la información sobre las causas de muerte es de gran importancia tanto para los países como para las instituciones sanitarias, en la medida en que contribuye a la evaluación y el seguimiento del estado de salud de la población y a la planificación de intervenciones sanitarias. El objetivo del estudio fue evaluar la proporción de causas de muerte mal definidas e imprecisas y su relación con el día de la semana y período lectivo de médicos residentes en el Hospital Italiano de Buenos Aires (HIBA) durante 2020. Métodos: se realizó un estudio analítico de corte transversal a partir de certificados médicos de defunción de pacientes fallecidos en el ámbito intrahospitalario, evaluando las causas de muerte mal definidas (términos médicos que no aportan información desde el punto de vista clínico y epidemiológico) y las imprecisas (no resultan lo suficientemente específicas como para identificar entidades nosológicas que permitan establecer acciones de prevención y control). Resultados: se analizaron 1030 certificados de defunción, con una proporción de certificados con causa básica de muerte mal definida del 2,3% (n =24), mientras que en el 17,4% (n =180) fue imprecisa. No se hallaron diferencias entre la proporción de causas básicas mal definidas y las imprecisas según el día de la semana o período lectivo. Al extender el análisis a todas las causas (básicas, mediatas e inmediatas), la proporción de causas mal definidas fue del 1,6% (n =40) y la de imprecisas del 51% (n =1212). Conclusiones: los resultados definen al HIBA como un centro de mediana calidad estadística en el registro de causas de muerte. Se concluye que es necesario mejorarla, para lo que resulta de interés la creación de un plan de capacitación y entrenamiento de los médicos en el grado y el posgrado.
