Intraoperative computed tomography for detection of residual stones in endourology procedures: systematic review and meta-analysis

ABSTRACT Background: Success rates in endourological procedures, notably percutaneous nephrolithotomy (PCNL) and ureteroscopy (URS), have demonstrated suboptimal outcomes, leading to more reinterventions and radiation exposure. Recently, the use of intraoperative computed tomography (ICT) scans has been hypothesized as a promising solution for improving outcomes in endourology procedures. With this considered, we conducted a comprehensive systematic review and meta-analysis encompassing all available studies that evaluate the impact of the use of intraoperative CT scans on surgical outcomes compared to conventional fluoroscopic-guided procedures. Methods: This systematic review was conducted in accordance with PRISMA guidelines. Multiple databases were systematically searched up to December of 2023. This study aimed to directly compare the use of an ICT scan with the standard non-ICT-guided procedure. The primary endpoint of interest was success rate, and the secondary endpoints were complications and reintervention rates, while radiation exposure was also evaluated. Data extraction and quality assessment were performed following Cochrane recommendations. Data was presented as an Odds ratio with 95%CI across trials and a random-effects model was selected for pooling of data. Results: A comprehensive search yielded 533 studies, resulting in the selection of 3 cohorts including 327 patients (103 ICT vs 224 in non-ICT). Primary outcome was significantly higher in the experimental group versus the control group (84.5% vs 41.4% respectively, 307 patients; 95% CI [3.61, 12.72]; p<0.00001; I2=0). Reintervention rates also decreased from 32.6% in the control to 12.6% in the ICT group (OR 0.34; 95%CI [0.12,0.94]; p =0.04; I2= 48%), whereas complication rates did not exhibit significant differences. Radiation exposure was also significantly reduced in two of the included studies. Conclusion: This meta-analysis highlights a favorable outcome with intraoperative CT scan use in PCNL procedures, showing a considerable increase in SFR when compared to standard fluoroscopy and nephroscopy. Despite limited studies, our synthesis underscores the potential of ICT scans to significantly reduce residual stones and their consequences for endourology patients, as reinterventions and follow-up ionizing radiation studies.

Kidney collecting system anatomy applied to endourology - a narrative review

ABSTRACT Objective: To evaluate the surgical anatomy of the kidney collecting system through a narrative review of the literature, highlighting its importance during diagnosis and its approach during surgical procedures for the treatment of renal stones. Material and Methods: We carried out a review about the anatomy of the kidney collecting system. We analyzed papers published in the past 40 years in the databases Pubmed, Embase and Scielo, and we included only papers in English and excluded case reports, editorials and opinions of specialists. Results: Renal collecting system could be divided in four groups: A1 - kidney midzone (KM), drained by minor calyx that are dependent on the superior or the inferior caliceal groups; A2 - KM drained by crossed calyx, one draining into the superior caliceal group and another draining into the inferior caliceal group; B1 - KM drained by a major caliceal group independent of both the superior and inferior groups; and B2 - KM drained by minor calyx entering directly into the renal pelvis. Some details and anatomic variations of the collecting system are related to clinical and radiological aspects, particularly perpendicular calyces, interpyelocalyx space, position of calyces in relation to renal border, classification of the renal collecting system, infundibular diameter and the angle between the lower infundibulum and renal pelvis. Conclusion: The knowledge of intra-renal collecting system divisions and variations as the angle between the renal pelvis and lower infundibula, position of the calices in relationship with renal edge and the diameter and position of the calyces are important for the planning of minimally invasive renal surgeries.

Investigación cualitativa en el contexto de la Salud Pública: actualización de conceptos

Los enfoques cualitativos en la investigación han sido fundamentales en las ciencias sociales y son cruciales para el estudio de la salud y los servicios sanitarios. Con el progreso en medicina, mayor especialización, expectativas crecientes de los pacientes y la complejidad de los servicios de salud, los profesionales se enfrentan a un entorno laboral cada vez más complicado. Los métodos cualitativos, aunque distintos de las técnicas experimentales y cuantitativas de la investigación clínica y biomédica, son indispensables para la investigación en servicios de salud. Esto se debe a que permiten explorar aspectos no medibles cuantitativamente, como las creencias sobre la salud, y porque proporcionan una base -descriptiva necesaria para la investigación cuantitativa, especialmente en campos con escasa investigación previa.

Qualitative approaches in research have been fundamental in the social sciences and are crucial to the study of health and health services. With progress in medicine, greater specialization, increasing patient expectations and the complexity of health services, professionals face an increasingly complicated work environment. Qualitative methods, although different from the experimental and quantitative techniques of clinical and biomedical research, are essential for health services research. This is because they allow us to explore aspects that are not quantitatively measurable, such as beliefs about health, and because they provide a necessary descriptive basis for quantitative research, especially in fields with little previous research.

¿Ensayos clínicos de superioridad, equivalencia o no inferioridad? / ¿Clinical trials of superiority, non-inferiority or equivalence?

La eficacia de una nueva intervención se establece generalmente a través de ensayos clínicos (EC) con asignación aleatoria (AA). Sin embargo, entre otros tantos desafíos metodológicos, el especificar la hipótesis de un EC con AA, sigue siendo un problema complejo de resolver para los investigadores clínicos. En este manuscrito discutimos las características de tres variantes de los EC con AA: EC de superioridad (ECS), EC de no-inferioridad (ECNI), y EC de equivalencia (ECE). Estos tres tipos de EC tienen supuestos diferentes sobre los efectos de una intervención, por lo que plantear hipótesis y definir objetivos requiere conocer algunos supuestos subyacentes a estos EC, incluso hasta elementos relacionados con la estimación del tamaño de muestra para cada cual. El objetivo de este manuscrito fue describir las diferencias metodológicas entre ECS, ECNI y ECE.

Efficacy and effectivity of new interventions are generally established through randomized clinical trials (RCTs). However, among many other methodological challenges, specifying the hypothesis of a RCT remains complex problem for clinical researchers. In this manuscript we discuss the characteristics of three variants of RCTs: superiority RCT (SRCT), non-inferiority RCT (NIRCT), and equivalence RCT (ERCT). These three types of RCT have different assumptions about the effects of an intervention, so setting hypotheses and defining objectives requires knowing some assumptions underlying these RCTs, including elements related to the estimation of the sample size for each one. The aim of this manuscript was to describe methodological differences between SRCT, NIRCT and ERCT.

What is the most dangerous sexual position that caused the penile fracture? A systematic review and meta-analysis

ABSTRACT Purpose: Penile fracture (PF) affects 1,14 to 10,48 men in every 100.000 men in East Asia, and the primary aetiology is sexual intercourse, but the knowledge regarding the most dangerous sexual position is not well explained. This study compares three sexual positions: man on top position (MTP), woman on top position (WTP), and doggy style position (DSP), leading to PF potential. Materials and methods: A search of sexual position-related PF in Google Scholar, PubMed, Cochrane, and PMC Europe was performed. Criteria inclusion was the full text of relevant articles which describ the number of sexual positions. It was analyzed by odds ratio, random model effect, and the OR and 95%CI were calculated. Results: Twelve relevant papers involving 490 patients comprised 169 MTP, 120 WTP, 158 DSP, and 43 no intercourse cases. Meta-analysis of all sexual positions was a MTP P= 0,04, WTP P=0,49, and DSP P=0,0005. Conclusions: The man-dominant positions (MTP and DSP) were significantly potential for PF, which speculated that when a man is dominant and very excited, intercourse may become highly vigorous and impact trauma. This study found that man's dominant position consists of DSP and the MTP significantly lead to PF.

Antecedentes de Andragogía en el proceso de gestión de personas mayores por profesionales de enfermería

Introducción: La gestión del cuidado de enfermería en personas mayores es todo un desafío en la actualidad para la profesión y más aún desde un enfoque andragógico. Objetivo: Exponer la fundamentación de los antecedentes de la andragogía en el proceso de gestión del cuidado de personas mayores por profesionales de enfermería. Métodos: Se realizó una revisión con el método de análisis bibliográfico a través de una búsqueda realizada entre los años 2010 al 2022, donde se consultaron bases de datos especializadas y se seleccionaron 33 publicaciones científicas sobre el tema. Resultados: El cuidado de personas mayores requiere una mirada transdisciplinaria y profesionales comprometidos con su cuidado. El profesional de enfermería responsable de la gestión debe considerar valores, actitudes y conocimientos de la disciplina que brindan una visión distinta y específica de la gestión de los cuidados. El avance científico ha permitido el incremento de la expectativa de vida de las personas, produciéndose un aumento significativo de personas mayores en el mundo manteniendo un adecuado cuidado como eslabón importante. La andragogía se encarga de la educación entre, para y por adultos y la asume como su objeto de estudio y realización, vista o concebida esta, como autoeducación, por lo cual, cobra importancia en los cuidados, pues interpreta el hecho educativo como un hecho andragógico, donde la educación y los cuidados se realizan como autoeducación. Conclusiones: Resulta importante la ejecución de investigaciones que beneficien el desarrollo del profesional de enfermería, para ayudar a disminuir las brechas que constan en la formación investigativa de estos profesionales y en las estructuras organizativas en las que estos se incorporan, dado en el proceso de gestión del cuidado de personas mayores desde un enfoque andragógico como mecanismo esencial.

Introduction: The management of nursing care in older people is a challenge for the profession today and even more so from an andragogical approach. Objective: To present the foundation of the background of andragogy in the process of managing the care of elderly people by nursing professionals. Methods: A review was carried out using the bibliographic analysis method through a search carried out between the years 2010 to 2022, where specialized databases were consulted and 33 scientific publications on the topic were selected. Results: Caring for the elderly requires a transdisciplinary approach and professionals committed to their care. The nursing professional responsible for the management must consider values, attitudes and knowledge of the discipline that provide a different and specific vision of care management. Scientific advances have allowed an increase in people's life expectancy, producing a significant increase in the number of older people in the world, maintaining adequate care as an important link. Andragogy is responsible for education among, for and by adults and assumes it as its object of study and realization, seen or conceived, as self-education, which is why andragogy gains importance in care, since it interprets the educational fact as an andragogical fact, where education and care are carried out as self-education. Conclusions: It is important to carry out research that benefits the development of nursing professionals, to help reduce the gaps that exist in the research training of these professionals and in the organizational structures in which they are incorporated, given in the care management process of older people from an andragogical approach as an essential mechanism.

Portuguese Advance Directives-a twist against futility? A cross sectional study

ABSTRACT BACKGROUND: Advance Directive documents allow citizens to choose the treatments they want for end-of-life care without considering therapeutic futility. OBJECTIVES: To analyze patients' and caregivers' answers to Advance Directives and understand their expectations regarding their decisions. DESIGN AND SETTING: This study analyzed participants' answers to a previously published trial, conceived to test the document's efficacy as a communication tool. METHODS: Sixty palliative patients and 60 caregivers (n = 120) registered their preferences in the Advance Directive document and expressed their expectations regarding whether to receive the chosen treatments. RESULTS: In the patient and caregiver groups, 30% and 23.3% wanted to receive cardiorespiratory resuscitation; 23.3% and 25% wanted to receive artificial organ support; and 40% and 35% chose to receive artificial feeding and hydration, respectively. The participants ignored the concept of therapeutic futility and expected to receive invasive treatments. The concept of therapeutic futility should be addressed and discussed with both the patients and caregivers. Legal Advanced Directive documents should be made clear to reduce misinterpretations and potential legal conflicts. CONCLUSION: The authors suggest that all citizens should be clarified regarding the futility concept before filling out the Advance Directives and propose a grammatical change in the document, replacing the phrase "Health Care to Receive / Not to Receive" with the sentence "Health Care to Accept / Refuse" so that patients cannot demand treatments, but instead accept or refuse the proposed therapeutic plans.

Quality of systematic reviews on the treatment of vesiculobullous skin diseases. A meta-epidemiological study

Abstract Background Systematic reviews of Randomized Controlled Trials (RCTs) are considered high-level evidence to support a decision on therapeutic interventions, and their methodological quality is essential to provide reliable and applicable results. Objective This meta-epidemiological study aimed to map and critically appraise systematic reviews assessing treatments for vesiculobullous skin diseases. Methods We conducted a comprehensive search strategy on MEDLINE (via Pubmed) in December 2022 without restrictions to find systematic reviews evaluating pharmacological interventions for vesiculobullous skin diseases. The methodological quality was assessed using the AMSTAR-2 tool, and additional information was extracted. We identified nine systematic reviews published between 2002 and 2021, seven assessing pemphigus. Results According to the AMSTAR-2 tool, 55.6% were classified as critically low quality, 22.2% as moderate quality, 11.1% as low and 11.1% as high quality. No review assessed the certainty of the evidence (GRADE); 86% of pemphigus reviews had at least two overlapping RCTs. There were some limitations regarding methodological flaws and the AMSTAR-2 tool use Conclusions These findings reveal a frail methodological quality of systematic reviews about vesiculobullous diseases treatment that may impact the results. Therefore, methodological rigor is mandatory for future systematic reviews to avoid duplication of effort and increase the certainty of the evidence supporting decision-making.

Protocolo do Nascer no Brasil II: Pesquisa Nacional sobre Aborto, Parto e Nascimento / Protocolo del Nacer en Brasil II: Encuesta Nacional sobre Aborto, Parto y Nacimiento / Protocol of Birth in Brazil II: National Research on Abortion, Labor and Childbirth

Resumo: Com o passar do tempo, o Brasil vem apresentando avanços na assistência obstétrica em hospitais públicos e privados; no entanto, ainda existem pontos frágeis que necessitam de atenção. O Ministério da Saúde, ciente dessa necessidade, financiou a segunda versão da pesquisa Nascer no Brasil. Os objetivos gerais são: avaliar a assistência pré-natal, ao parto e nascimento, ao puerpério e ao aborto, comparando com os resultados do Nascer no Brasil I, e analisar os principais determinantes da morbimortalidade perinatal; avaliar a estrutura e processos assistenciais dos serviços de obstetrícia e neonatologia das maternidades; analisar os conhecimentos, atitudes e práticas de profissionais de saúde que prestam assistência ao parto e ao aborto; e identificar as principais barreiras e facilitadores para essa assistência no país. Com escopo nacional e amostra probabilística em dois estágios (1-hospitais e 2-mulheres), dividida em 59 estratos, foram selecionados 465 hospitais com total planejado de, aproximadamente, 24.255 mulheres, 2.205 por motivo de aborto e 22.050 por motivo de parto. A coleta de dados, realizada por meio de seis instrumentos eletrônicos, ocorre durante a internação hospitalar para o parto ou aborto, com duas ondas de seguimento, aos dois e quatro meses. Com o intuito de expandir o número de casos de morbidade materna grave, mortalidade materna e perinatal, três estudos caso controle foram incorporados ao Nascer no Brasil II. O trabalho de campo foi iniciado em novembro de 2021 com término previsto para 2023. Os resultados permitirão comparar a atenção atual ao parto e ao nascimento com a retratada no primeiro inquérito e, com isso, avaliar os avanços alcançados no decorrer desses 10 anos.

Resumen: Aunque Brasil ha presentado avances en la atención obstétrica en hospitales públicos y privados, todavía hay puntos débiles que necesitan atención. El Ministerio de Salud, consciente de esta necesidad, financió la segunda versión de la encuesta Nacer en Brasil. Los objetivos generales son: evaluar la atención prenatal, el parto y el nacimiento, el puerperio y el aborto, comparando con los resultados del Nacer en Brasil I, y analizar los principales determinantes de la morbimortalidad perinatal; evaluar la estructura y los procesos de atención de los servicios de obstetricia y neonatología en las maternidades; analizar los conocimientos, prácticas y actitudes de los profesionales de la salud que brindan atención para el parto y el aborto; e identificar las principales barreras y facilitadores para esta atención en el país. Tiene un alcance nacional y muestra probabilística en dos etapas (1-hospitales y 2-mujeres), la cual se dividió en 59 estratos; y se seleccionaron 465 hospitales con un total planificado de aproximadamente 24.255 mujeres, de las cuales 2.205 tuvieron procedimientos por aborto y 22.050 por parto. Para la recolección de datos se aplicó seis instrumentos electrónicos, que se realizó durante la hospitalización por parto o aborto, con dos rondas de seguimiento, a los dos y cuatro meses. Con el fin de ampliar el número de casos de morbilidad materna grave, mortalidad materna y perinatal, se incorporaron tres estudios de casos y controles en Nacer en Brasil II. El trabajo de campo comenzó en noviembre de 2021 y finalizará en 2023. Los resultados nos permitirán evaluar la atención al parto y al nacimiento actual con lo que se retrató en la primera encuesta, de esta manera se podrá evaluar los avances alcanzados a lo largo de estos 10 años.

Abstract: Brazil has made advances in obstetric care in public and private hospitals; however, weaknesses in this system still require attention. The Brazilian Ministry of Health, aware of this need, funded the second version of the Birth in Brazil survey. This study aimed to evaluate: prenatal, labor and birth, postpartum, and abortion care, comparing the results with those of Birth in Brazil I; and analyze the main determinants of perinatal morbidity and mortality; evaluate the care structure and processes of obstetrics and neonatology services in maternity hospitals; analyze the knowledge, practices, and attitudes of health professionals who provide birth and abortion care; and identify the main barriers and facilitators related to care of this nature in Brazil. With a national scope and a 2-stage probability sample: 1-hospitals and 2-women, stratified into 59 strata, 465 hospitals were selected with a total planned sample of around 24,255 women - 2,205 for abortion reasons and 22,050 for labor reasons. Data collection was conducted using six electronic instruments during hospital admission for labor or abortion, with two follow-up waves, at two and four months. In order to expand the number of cases of severe maternal morbidity, maternal and perinatal mortality, three case control studies were incorporated into Birth in Brazil II. The fieldwork began in November 2021 and is scheduled to end in 2023. It will allow a comparison between current labor and birth care results and those obtained in the first study and will evaluate the advances achieved in 10 years.

Unmet need for and impact of adopting immunobiological drugs for moderate to severe plaque psoriasis in a pediatric population

ABSTRACT Objective Therefore, this study aimed to evaluate the impact of secukinumab and ustekinumab against moderate-to-severe plaque psoriasis in a Brazilian pediatric population with access to public healthcare. Methods A survey of immunobiological treatments registered for use against pediatric psoriasis at the National Health Surveillance Agency was conducted. These treatments were compared to the list available in the same treatment category in the public health system through the Clinical Protocol and Therapeutic Guidelines for psoriasis. A quantitative analysis of the data of patients treated with immunobiological drugs the previous year in accordance with the Clinical Protocol and Therapeutic Guidelines was performed using data available in the DATASUS portal. Results The public budget impact scenarios analyzed were comparable to the investment already planned for acquiring the only available drug option. Conclusion The incorporation of two therapeutic options in the Clinical Protocol and Therapeutic Guidelines list for moderate-to-severe pediatric psoriasis was feasible in a horizon of 5 years compared to the investment into the single option available to pediatric patients. These findings can facilitate the local analysis of budgetary impact and discussions on the feasibility of this therapeutic incorporation at the state level.

"nem sempre funciona, mas ajuda": percepções parentais sobre a exposição do bebê às telas / "it doesn't always work, but it helps": parental perceptions of baby's screen exposure

RESUMO. Frente ao número crescente de crianças menores de dois anos expostas às telas, preocupações com o desenvolvimento dos bebês têm emergido e sido foco de discussões acadêmicas e clínicas. Para buscar compreender as razões que levam os pais a disponibilizarem as mídias digitais aos bebês, entrevistas foram conduzidas com mães e pais de crianças com idades entre dez e 17 meses, domiciliados na região metropolitana de Porto Alegre, Brasil. Apesar das orientações das sociedades de pediatria, verifica-se discrepância entre a divulgação deste conteúdo e o acesso a ele. Os pais, por desconhecimento e também por necessidade, disponibilizam diferentes mídias ao bebê, que é percebida em diversas situações como positiva e facilitadora nos cuidados com a criança; os pais alegam que o acesso precoce pelo bebê é importante para aprimorar a destreza cognitiva e capaz de gerar interação familiar. Por outro lado, apresentam preocupações diante do uso de telas em detrimento de outras formas de brincar. Evidencia-se que os pais precisam de orientações e suporte, assim como os profissionais devem considerar as necessidades das famílias ao elaborar diretrizes a fim de orientá-los.

RESUMEN Frente al creciente número de niños menores de dos años expuestos a las pantallas, preocupaciones sobre el desarrollo de los bebés han sido el foco de discusiones académicas y clínicas. Para comprender porque madres y padres exponen a sus hijos a tecnologías digitales se han realizado entrevistas en profundidad con madres y padres de bebés con edades entre 10 y 17 meses, domiciliadas en la región metropolitana de Porto Alegre, Brasil. A pesar de las pautas recomendadas por las sociedades pediátricas sobre al acceso a las pantallas, los padres muestran discrepancia acerca de las mismas. Los progenitores, debido tanto a la falta de conciencia, como a la necesidad comparten sus dispositivos con los bebés. Los padres afirman estar preocupados por el futuro de los niños y perciben el acceso temprano a la tecnología como una herramienta importante para mejorar las habilidades cognitivas y fortalecer los lazos familiares. También señalaron que las potencialidades en el uso para generar interacciones familiares, destacando la supervisión de los padres. Por otro lado, los padres manifiestan preocupación ante el uso de la tecnología a expensas de otras formas de juego. Los progenitores necesitan orientación y apoyo, al igual que los profesionales deben considerar las necesidades de las familias al formular recomendaciones.

ABSTRACT. Considering the large number of children under the age of two that are constantly exposed to digital screens, concerns about child development have been emerging and becoming the focus of academic and clinical discussions. In order to understand the reasons why parents expose their infants to digital technologies, we conducted in-depth interviews with mothers and fathers of infants aged between 10 and 17 months living in the metropolitan region of Porto Alegre, Brazil. Despite the guidelines of local pediatric societies, our data points to divergences between what is recommended by the board of pediatrics and the patterns of screen exposure documented in our study. Parents, out of unawareness and/or urgent need, introduce their babies to digital technologies. Parents claimed to be concerned with the future of children and perceived early access to digital technology as an important tool to improve cognitive skills and to strength family bonds. Conversely, parents had concerns in face of technology at the expense of other forms of play. Our findings highlight that parents need additional guidance and support, while professionals should weight needs and daily challenges experienced by families when formulating guidelines.

Precarious work and methodological challenges to study hard-to-reach populations

ABSTRACT OBJECTIVE To describe the methodological challenges and strategies of a web survey on the working conditions and health among delivery workers. METHODS The study population consisted of Brazilian delivery workers operating in the national territory. Procedures include building solid and ongoing collaboration with worker representatives and conducting a four-month data collection from February to May 2022, sharing the link to the online questionnaire on social media such as social networks (Facebook, Instagram) and messaging apps (WhatsApp, Telegram). RESULTS The recruitment of 41 leaders or influencers of delivery workers increased the dissemination of the study, some of whom participated in the consensual validation of the questionnaire; the production of content for social media for the dissemination of the questionnaire link on social networks and applications, and the in-person dissemination of the study at the delivery workers' meeting points during the workday played a fundamental role, totaling around 132 hours in 45 shifts. The strategies adopted for data collection with a hybrid approach to dissemination made it possible to carry out the web survey. After four months of the web survey, 564 delivery workers, 543 men and 18 women, responded to the online questionnaire. CONCLUSION The web survey presented methodological strategies to overcome the challenge of reaching workers, including hybrid work, to increase the participation of workers, on whom epidemiological research is still scarce.

Efficacy of a Hospital Discharge Transition Plan in the care competence of patients with chronic conditions and their family caregivers: a clinical trial / Eficacia del Plan Transicional de Alta Hospitalaria en la competencia para el cuidado del paciente con condición crónica y su cuidador familiar: ensayo clínico / Eficácia do Plano Transicional de Alta Hospitalar na competência para o cuidado de pacientes com condições crônicas e seu cuidador familiar: ensaio clínico

Objective: to assess the efficacy of a Hospital Discharge Transition Plan in the care competence and in adherence to the therapy of dyads comprised by patients with non-communicable chronic diseases and their caregivers. Method: a controlled and randomized clinical trial; the sample was comprised by 80 dyads of patients with chronic conditions and their caregivers, randomly allocated as follows: 40 to the control group and another 40 to the intervention group. The instruments to characterize the patient-caregiver dyad, the patients' and caregivers' care competence and the patients' adherence to the treatment scale were applied. The " CUIDEMOS educational intervention" was applied to the intervention group; in turn, the control group was provided usual care with the aid of a booklet, with phone follow-up via at month 1. Results: 52.5% of the patients and 81.3% of the caregivers were women. The patients' and caregivers' mean ages were 69.5±12.6 and 47.5±13.1 years old, respectively. The Hospital Discharge Transition Plan increased the scores in the "knowledge", "uniqueness", "instrumental", "enjoying", "anticipation" and "social relations" dimensions, as well as the global care competence of the patients and family caregivers; in addition to the following factors: medications, diet, stimulants control, weight control, stress management, and global adherence to the therapy by the patient. There were no statistically significant differences between the control and intervention groups. Conclusion: the Hospital Discharge Transition Plan increased the patients' and family caregivers' care competence after the intervention, as well as the patients' adherence to the treatment. However, there were no differences between the control and intervention groups, possibly due to the similarity of the activities.

Educational video for teaching safe practices in the perioperative period: randomized controlled trial / Video educativo para enseñanza de prácticas seguras en el perioperatorio: ensayo clínico aleatorizado / Vídeo educativo para ensino de práticas seguras no perioperatório: ensaio clínico randomizado

Objective: to assess the effectiveness of an educational video on hospitalized patients' knowledge of safe practices in the perioperative period. Method: randomized, double-blind controlled trial carried out in a teaching hospital in the countryside of Minas Gerais. 100 participants undergoing elective orthopaedic surgery were randomly allocated (50 participants in the experimental group and 50 participants in the control group). Patient knowledge was assessed using a questionnaire constructed by the researchers and validated by specialists, before and after the intervention (educational video) or standard guidelines were applied. Descriptive statistics were used for quantitative variables and Student's t-test for independent samples to analyze the mean difference in knowledge between the experimental and control groups (α = 0.05). Results: 100 participants took part in the study, 50 participants in the experimental group and 50 participants in the control group. The experimental group showed a significantly higher gain in knowledge (t =3.72 ±1.84; p<0.001) than the control group. Cohen's d was 1.22, indicating a large magnitude of the effect. Conclusion: the educational video was effective in improving patients' knowledge and can contribute to nurses in the practice of health education, optimizing time and disseminating knowledge about safe practices in the perioperative period.

What is an "ongoing" clinical trial? An analysis of different sources revealed heterogeneous definitions of when a clinical trial starts and ends: a meta-research study

ABSTRACT BACKGROUND: Although the concept of an "ongoing study" seems self-explanatory, it is difficult to determine whether a trial is underway. OBJECTIVE: To analyze the definitions of "ongoing clinical trial" across different clinical trial registries, methodological guidelines, and other sources. DESIGN AND SETTING: This meta-research study was conducted at the Universidade Federal de São Paulo (UNIFESP), Brazil. METHODS: We performed a cross-sectional analysis of relevant clinical trial registry databases, methodological guidelines for conducting systematic reviews, and other sources that would define or regulate clinical trials. RESULTS: We identified various heterogeneous definitions used by eligible sources at both the start and end of a clinical trial. The starting criteria used were as follows: when the team is planning the protocol, when permission is given to conduct the study, or when the first participant is enrolled. Some sources used the time at which the last outcome data was collected as a criterion to determine the end of the trial. The International Committee of Medical Journal Editors stated that a study is still "ongoing" during the analysis process. Several sources use a vague definition or present no clear criteria for defining the start or end of a study. CONCLUSION: The concept of "ongoing clinical trials" lacks a transparent and homogeneous definition across relevant sources. A consensus on this concept is important to facilitate the evaluation of available evidence and conduct research synthesis. Further efforts are necessary to determine the best definition for the start and end of a clinical trial.

Effect of lncRNA HIF1A-AS1 on chemotherapy sensitivity of vincristine-resistant in retinoblastoma cells / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To investigate the effect of long non-coding RNA-HIF1A-AS1(lncRNA HIF1A-AS1)on the chemotherapy sensitivity of vincristine(VCR)-resistant in retinoblastoma(RB)cells by regulating the expression of hypoxia-inducible factor-1α(HIF-1α).METHODS: The human RB VCR-resistant cell line SO-RB50/VCR was established, expression of lncRNA HIF1A-AS1 in SO-RB50 and SO-RB50/VCR cells were detected by reverse transcription-quantitative real-time PCR(RT-qPCR); inhibition of lncRNA HIF1A-AS1 expression or simultaneous overexpression of HIF-1α in SO-RB50/VCR cells, and then median inhibitory concentration(IC50)of VCR and cell proliferation and apoptosis were detected in SO-RB50/VCR cells; the protein expressions of HIF-1α, multidrug resistance associate protein(MRP)and P-glycoprotein(P-gp)were measured by Western blot.RESULTS: Compared with SO-RB50 cells, the expression levels of lncRNA HIF1A-AS1 and HIF-1α protein in SO-RB50/VCR cells were increased(P&#x003C;0.05); after inhibiting the expression of lncRNA HIF1A-AS1 in SO-RB50/VCR cells, the apoptosis rate was significantly increased(P&#x003C;0.05), optical density(OD450), the IC50 value of VCR on cells and the expression levels of HIF-1α, MRP and P-gp proteins were significantly reduced(P&#x003C;0.05); overexpression of HIF-1α attenuates the inhibitory effect of down-regulated lncRNA HIF1A-AS1 expression on drug resistance in SO-RB50/VCR cells.CONCLUSION: The lncRNA HIF1A-AS1 was highly expressed in SO-RB50/VCR cells, and inhibition of lncRNA HIF1A-AS1 expression reduced VCR resistance in SO-RB50/VCR cells by down-regulating HIF-1α expression.
