Experimental Model Exposed to Bisphenol and Submitted to a High-Fat Diet and Related Morphologic Testicular Parameters Alterations Analysis

ABSTRACT Purpose To evaluate the morphological and stereological parameters of the testicles in mice exposed to bisphenol S and/or high-fat diet-induced obesity. Material and Methods Forty adult male C57BL/6 mice were fed a standard diet (SC) or high-fat diet (HF) for a total of 12 weeks. The sample was randomly divided into 4 experimental groups with 10 mices as follows: a) SC - animals fed a standard diet; b) SC-B - animals fed a standard diet and administration of BPS (25 μg/kg of body mass/day) in drinking water; c) HF: animals fed a high-fat diet; d) HF-B - animals fed a high-fat diet and administration of BPS (25 μg/Kg of body mass/day) in drinking water. BPS administration lasted 12 weeks, following exposure to the SC and HF diets. BPS was diluted in absolute ethanol (0.1%) and added to drinking water (concentration of 25 μg/kg body weight/day). The animals were euthanized, and the testes were processed and stained with hematoxylin and eosin (H&E) for morphometric and stereological parameters, including density of seminiferous tubules per area, length density and total length of seminiferous tubules, height of the tunica albuginea and the diameter of the seminiferous tubules. The images were captured with an Olympus BX51 microscope and Olympus DP70 camera. The stereological analysis was done with the Image Pro and Image J programs. Means were statistically compared using ANOVA and the Holm-Sidak post-test (p<0.05). Results The seminiferous tubule density per area reduced in all groups when compared with SC samples (p<0.001): HF (40%), SC-B 3(2%), and HF-B (36%). Length density was reduced significantly (p<0.001) in all groups when compared with SC group: HF (40%), SC-B (32%), and HF-B (36%). The seminiferous tubule total length was reduced (p<0.001) when compared to f HF (28%) and SC-B (26%) groups. The tubule diameter increased significantly (p<0.001) only when we compared the SC group with SC (54%) an SC-B (25%) groups and the tunica thickness increased significantly only in HF group (117%) when compared with SC-B (20%) and HF-B 31%. Conclusion Animals exposed to bisphenol S and/or high-fat diet-induced obesity presented important structural alterations in testicular morphology.

Primary Retroperitoneal Lymph Node Dissection for Clinical Stage II A/B Seminomas: A Systematic Review and Meta-Analysis

ABSTRACT Introduction Chemotherapy and radiation therapy are considered standard treatments for stage II seminoma patients; however, these therapies are associated with long-term toxicities. Recently, retroperitoneal lymph node dissection has emerged as an alternative strategy, and the first three phase II trials were published in 2023 with promising results. The present study conducted a systematic review and meta-analysis to evaluate this surgery as an alternative treatment for stage IIA/B seminoma patients. Purpose Seminomas are the most common testicular tumors, often affecting young adult males. Standard treatments for stage II seminomas include chemotherapy and radiation therapy, but these therapies are associated with long-term toxicities. Thus, identifying alternative strategies is paramount. Herein, we conducted a systematic review and meta-analysis to appraise the efficacy and safety of retroperitoneal lymph node dissection (RPLND) for treating this condition. Methods We systematically searched the PubMed, Embase, and Cochrane databases for studies evaluating RPLND as a primary treatment for stage II A/B seminomas. Using a random-effects model, single proportion and means and pooled 2-year recurrence-free survival rates with hazard rates and 95% CI were calculated. Results Seven studies were included, comprising 331 males with stage II seminomas. In the pooled analysis, the recurrence rate was 17.69% (95% CI 12.31-24.75), and the 2-year RFS rate was 81% (95% CI 0.77-0.86). The complication rate was 9.16% (95% CI 6.16-13.42), the Clavien-Dindo > 2 complication rate was 8.83% (95% CI 5.76-13.31), and the retrograde ejaculation rate was 7.01% (95% CI 3.54-13.40). The median operative time was 174.68 min (95% CI 122.17-249.76 min), median blood loss was 105.91 mL (95% CI 46.89-239.22 mL), and patients with no evidence of lymph node involvement ranged from 0-16%. Conclusions Primary RPLNDs for treating stage IIA/B seminomas have favorable RFS rates, with low complication and recurrence rates. These findings provide evidence that this surgery is a viable alternative therapy for these patients.

Use of ChatGPT in Urology and its Relevance in Clinical Practice: Is it useful?

ABSTRACT Purpouse: One of the many artificial intelligence based tools that has gained popularity is the Chat-Generative Pre-Trained Transformer (ChatGPT). Due to its popularity, incorrect information provided by ChatGPT will have an impact on patient misinformation. Furthermore, it may cause misconduct as ChatGPT can mislead physicians on the decision-making pathway. Therefore, the aim of this study is to evaluate the accuracy and reproducibility of ChatGPT answers regarding urological diagnoses. Materials and Methods: ChatGPT 3.5 version was used. The questions asked for the program involved Primary Megaureter (pMU), Enuresis and Vesicoureteral Reflux (VUR). There were three queries for each topic. The queries were inserted twice, and both responses were recorded to examine the reproducibility of ChatGPT's answers. Afterwards, both answers were combined. Finally, those rwere evaluated qualitatively by a board of three specialists. A descriptive analysis was performed. Results and Conclusion: ChatGPT simulated general knowledge on the researched topics. Regarding Enuresis, the provided definition was partially correct, as the generic response allowed for misinterpretation. For VUR, the response was considered appropriate. For pMU it was partially correct, lacking essential aspects of its definition such as the diameter of the dilatation of the ureter. Unnecessary exams were suggested, for Enuresis and pMU. Regarding the treatment of the conditions mentioned, it specified treatments for Enuresis that are ineffective, such as bladder training. Therefore, ChatGPT responses present a combination of accurate information, but also incomplete, ambiguous and, occasionally, misleading details.

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.

Linfangioma Quístico del Páncreas. Un Tumor poco Frecuente / Pancreas Cystic Lymphangioma. A Rare Tumor

El linfangioma quístico del páncreas (LQP), es un tumor extremadamente raro y representa solo el 1% de los linfangiomas abdominales. El objetivo de este manuscrito fue reportar un caso de LQP intervenido quirúrgicamente; y revisar la evidencia existente respecto de sus características morfológicas, terapéuticas y pronósticas. Mujer de 67 años, con LQP operada en Clínica RedSalud Mayor Temuco en septiembre de 2023. Se verificó un tumor sólido-quístico de 16 cm de diámetro mayor, adherido al páncreas a nivel del cuerpo de la glándula, de 867 gramos de peso, con líquido amarillento en su interior; la que fue extirpada completamente. Después del estudio histológico, se realizaron tinciones inmunohistoquímicas complementarias para CD31, D2-40 y calretina. La paciente tuvo un curso postoperatorio sin incidentes, siendo dado de alta al tercer día postoperatorio. En el control alejado, se encontraba en buenas condiciones generales. El LQP es un tumor muy poco frecuente. Las características clínicas e imágenes de este tipo de lesiones son inespecíficas. Debe considerarse en el diagnóstico diferencial de las lesiones quísticas pancreáticas. La resección quirúrgica completa con márgenes libres es el tratamiento de elección; y el pronóstico del LQP es favorable si se reseca por completo.

SUMMARY: Pancreas cystic lymphangioma (PCL) are extremely rare, accounting for only 1% of abdominal lymphangiomas. The aim of this study was to report a rare case of PCL, who underwent surgery; and review the existing evidence regarding its morphological, therapeutic and prognostic characteristics. 67-year-woman patient with PCL who underwent surgery at Clínica RedSalud Mayor Temuco in September 2023. In this case, a solid-cystic tumor with a major diameter of 16 cm was identified, adhering to the pancreas at the level of the body of the gland, weighing 867 grams and containing yellowish fluid in its interior. The tumor was completely excised. Subsequent to histological examination, additional immunohistochemical staining was performed for CD31, D2-40, and calretinin. The patient experienced an uneventful postoperative course and was discharged on the third postoperative day. During the follow-up, the patient remains in good general condition. LQP is a very rare tumor. Clinical features and images of this type of lesions are nonspecific. It should be considered in the differential diagnosis of pancreatic cystic lesions. Complete surgical resection with free margins is the treatment of choice; and the prognosis of LQP is favorable if it is completely resected.

Taxa e custos médicos diretos de cesáreas em beneficiárias da saúde suplementar no estado de São Paulo, Brasil: 2015 a 2021 / Rate and direct medical costs of cesarean sections among supplementary health plan holders living in the state of São Paulo, Brazil: 2015-2021

Resumo O Brasil tem a segunda maior taxa de cesárea do mundo. Há diferença dessas taxas nos setores públicos e privados. Foram utilizados dados de internação de beneficiárias residentes no estado de São Paulo, internadas entre 2015 e 2021, com idades entre 10 e 49 anos, para verificar as taxas e custos das cesáreas no setor privado. Foi realizado estudo parcial de avaliação econômica em saúde na perspectiva da saúde suplementar considerando custos médicos diretos de internação. Foram analisadas 757.307 internações, com gasto total de R$ 7,701 bilhões. As taxas de cesáreas foram de 80% no período. São menores nas gestantes mais novas (69%) e maiores nas mais velhas (86%), e sempre superiores a 67%. Essa população tem taxas 71% maiores do que aquelas do SUS. Há maior proporção de internações com uso de unidade de terapia intensiva nas cesáreas. O custo mediano da cesárea é 15% maior do que o parto normal e são duas vezes maiores nas seguradoras do que nas cooperativas médicas. Há oportunidade de aplicação de políticas públicas de saúde amplamente utilizadas no Sistema Único de Saúde visando a redução das taxas, dos custos diretos da internação e dos planos de saúde.

Abstract Brazil has the second largest cesarean section rate in the world. Differences in rates exist between the public and private health sectors. This study used data on admissions of supplementary health plan holders aged between 10 and 49 years living in the state of São Paulo admitted between 2015 and 2021 to determine cesarean section rates and costs in the private health sector. We conducted a partial economic analysis in health from a supplementary health perspective focusing on the direct medical costs of admissions. A total of 757,307 admissions were analyzed with total costs amounting to R$7.701 billion. The cesarean section rate over the period was 80%. Rates were lowest in young women (69%) and highest in the oldest age group (86%), exceeding 67% across all groups. The rate was 71% higher than in public services. The proportion of admissions with use of the intensive care unit was higher among cesarian deliveries. The median cost of a cesarean was 15% higher than that of a normal delivery and twice as high in insurance companies than healthcare cooperatives. There is an opportunity to apply policies that are widely used in public services to the private sector with the aim of reducing cesarean rates in private services, direct costs of admission, and the cost of supplementary health plans.

Retrospective study of patients submitted to appendectomy in a tertiary hospital: is there a difference between the public and supplementary health system?

Introduction: Appendicitis is the surgical disease with the highest prevalence in emergency rooms. Its clinical and/or surgical complications are associated with the time course of symptoms, age, comorbidities, and stages of the disease. Objectives: To analyze the demographic and clinical data of patients who underwent appendectomy for acute appendicitis in a tertiary referral hospital in the city of São Paulo and compare these data between services provided by the Public and Supplementary Health System. Methodology: Retrospective analysis of data from electronic medical records of patients over 14 years old who underwent appendectomy for acute appendicitis at Hospital Santa Marcelina, both in the Public and Supplementary Health Systems from January 2015 to December 2017. Results: A total of 536 patients were analyzed, 354 (66%) of whom were male with a general mean age of 29.85 years (14-81 years). The mean time from symptoms to seeking medical care was 53.84 hours. Regarding the phases of acute appendicitis, a greater number of cases of complicated disease was observed in patients operated on in the Public Health System (p < 0.0001), as well as the time course of symptoms (p = 0.0005) and Conclusion: There was a predominance of male patients undergoing appendectomy for acute appendicitis, with longer time course of symptoms in those operated on in the Public Health System and a predominance of appendicitis in advanced stages (3 and 4) in this group. However, in this group there was no significant increase in the rate of postoperative infection, and the length of stay was shorter than that of patients operated on in the Supplementary Health System.

Head-to-head comparisons of enhanced CT, 68Ga-PSMA-11 PET/CT and 18F-FDG PET/CT in identifying adverse pathology of clear-cell renal cell carcinoma: a prospective study

ABSTRACT Objectives: Accurate preoperative prediction of adverse pathology is crucial for treatment planning of renal cell carcinoma (RCC). Previous studies have emphasized the potential of prostate-specific membrane antigen positron emission tomography / computed tomography (PSMA PET/CT) in differentiating between benign and malignant localized renal tumors. However, there is a scarcity of case reports elucidating the identification of aggressive pathological features using PET/CT. Our study was designed to prospectively compare the diagnostic value of enhanced CT, 68Ga-PSMA-11 and 18F-fluorodeoxyglucose (18F-FDG) PET/CT in clear-cell renal cell carcinoma (ccRCC) with necrosis or sarcomatoid or rhabdoid differentiation. Materials and Methods: A prospective case series of patients with a newly diagnosed renal mass who underwent enhanced CT, 68Ga-PSMA-11 and 18F-FDG PET/CT within 30 days prior to nephrectomy was included. Complete preoperative and postoperative clinicopathological data were recorded. Patients who received neoadjuvant targeted therapy, declined enhanced CT or PET/CT scanning, refused surgical treatment or had non-ccRCC pathological indications were excluded. Radiological parameters were compared within subgroups of pathological characteristics. Bonferroni corrections were used to adjust for multiple testing and statistical significance was set at a p-value less than 0.017. Results: Seventy-two patients were available for the final analysis. Enhanced CT demonstrated poor performance in identifying necrosis, sarcomatoid or rhabdoid differentiation and adverse pathology (all P > 0.05). The maximum standardized uptake value (SUVmax) of 68Ga-PSMA-11 PET/CT was more effective than 18F-FDG PET/CT in identifying tumor necrosis and adverse pathology, with an area under the curve (AUC) of 0.85 (cutoff value=25.26, p<0.001; Delong test z=2.709, p=0.007) for tumor necrosis and AUC of 0.90 (cutoff value=25.26, p<0.001; Delong test z=3.433, p<0.001) for adverse pathology. However, no significant statistical difference was found between 68Ga-PSMA-11 and 18F-FDG PET/CT in predicting sarcomatoid or rhabdoid feature (AUC of 0.91 vs.0.75, Delong test z=1.998, p=0.046). Subgroup analyses based on age, sex, tumor location, maximal diameter, stage and WHO/ISUP grade demonstrated that 68Ga-PSMA-11 PET/CT SUVmax had a significant predictive value for adverse pathology. Enhanced CT value and SUVmax demonstrated strong reliability [intraclass correlation coefficient (ICC) > 0.80], indicating a robust correlation. Conclusions: 68Ga-PSMA-11 PET/CT demonstrates distinct advantages in identifying aggressive pathological features of primary ccRCC when compared to enhanced CT and 18F-FDG PET/CT. Further research and assessment are warranted to fully establish the clinical utility of 68Ga-PSMA-11 PET/CT in ccRCC.

Single Port Robotic Pyeloplasty: early single-center experience

ABSTRACT Purpose: Ureteropelvic junction obstruction (UPJO) is a prevalent cause of hydronephrosis, especially in young patients. The treatment paradigm for this condition has shifted from open to minimally invasive pyeloplasty. In the present study we describe our initial single centre experience with single port (SP) robot-assisted pyeloplasty (RAP) via periumbilical incision. Material and methods: With the patient in a 60-degree left flank position, the SP system is docked with the Access port (Intuitive Surgical, Sunnyvale, CA, US) placed in a periumbilical 3 cm incision. Robotic instruments are deployed as follows: camera at 12 o'clock, bipolar grasper at 9 o'clock, scissors at 3 o'clock and Cadiere at 6 o'clock. After isolation and identification of the ureter and the ureteropelvic junction (UPJ), the ureter is transected at this level and then spatulated. Anastomosis is carried out by two hemicontinuous running sutures, over a JJ stent. Results: Between 2021 and 2023, a total of 8 SP RAP have been performed at our institution, with a median (interquartile range, IQR) of 23 years (20.5-36.5). Intraoperative outcomes showed a median (IQR) OT of 210.5 minutes (190-240.5) and a median (IQR) estimated blood loss (EBL) of 50 mL (22.5-50). No postoperative complications were encountered, with a median (IQR) length of stay (LOS) of 31 hours (28.5-34). Conclusion: In the present study we evaluated the feasibility and safety of SP RAP. The observed outcomes and potential benefits, combined with the adaptability of the SP platform, hold promising implications for the application of SP system in pyeloplasty treatment.

Resource utilization and costs related to the management of obstructive hypertrophic cardiomyopathy under the Brazilian supplementary healthcare system´s perspective: results from a modified Delphi panel / Utilização de recursos e custos relacionados ao manejo da cardiomiopatia hipertrófica obstrutiva sob a perspectiva do sistema de saúde suplementar brasileiro: resultados de um painel Delphi modificado

Objective: To generate data on the costs associated with the diagnosis and treatment of obstructive ypertrophic cardiomyopathy (HCM) from the perspective of the private health system in Brazil. Methods: A modified Delphi panel including seven different specialists (three clinical cardiologists with experience in obstructive HCM, two hemodynamicists with experience in septal ablation and two cardiac surgeons with expertise in myectomy), from two Brazilian states (São Paulo and Pernambuco), was conducted between August and November 2022. Two rounds of questions about the use of healthcare resources according to the functional class (NYHA I-IV) and a panel in a virtual platform were conducted to obtain the final consensus. Micro-costing defined costs and unit values were determined based on official price lists. Results: The total diagnosis cost per patient was estimated at BRL 11,486.81. The obstructive HCM management costs analysis showed average annual costs per patient of BRL 17,026.74, BRL 19,401.46, BRL 73,310.07, and BRL 94,885.75 for the functional classes NYHA I, NYHA II, NYHA III, and NYHA IV, respectively. The average costs per patient related to procedures in a year were BRL 12,698.53, BRL 13,462.30, BRL 58,841.67, and BRL 75,595.90 for the functional classes NYHA I, II, III, and IV, respectively. Conclusions: The annual costs of HCM management increased according to the functional class, highlighting the need for safe and effective strategies to improve patient's NYHA functional class while promoting a decrease in the need for invasive therapies.

Objetivo: Gerar dados acerca dos custos associados ao diagnóstico e tratamento da cardiomiopatia hipertrófica (CMH) obstrutiva, sob a perspectiva do sistema de saúde privado no Brasil. Métodos: Um painel Delphi modificado incluindo sete especialistas (três cardiologistas clínicos com experiência em CMH obstrutiva, dois hemodinamicistas com experiência em ablação de septo e dois cirurgiões cardíacos com experiência em miectomia) de dois estados brasileiros (São Paulo e Pernambuco) foi conduzido entre agosto e novembro de 2022. Foram realizadas duas rodadas de perguntas acerca da utilização de recursos de acordo com a classe funcional (NYHA I-IV) e uma reunião virtual para obtenção do consenso final. Os custos foram definidos por meio de microcusteio, e os valores unitários foram definidos com base em listas de preço oficiais. Resultados: O custo total do diagnóstico por paciente foi estimado em R$ 11.486,81. A análise de custos de manejo da CMH obstrutiva mostrou custos médios anuais por paciente de R$ 17.026,74, R$ 19.401,46, R$ 73.310,07 e R$ 94.885,75 para as classes funcionais NYHA I, NYHA II, NYHA III e NYHA IV, respectivamente. Os custos médios por paciente relacionados a procedimentos em um ano foram de R$ 12.698,53, R$ 13.462,30, R$ 58.841,67 e R$ 75.595,90 para as classes NYHA I, II, III e IV, respectivamente. Conclusões: Os custos anuais com o manejo da CMH aumentam de acordo com a classe funcional, destacando a necessidade de estratégias seguras e eficazes capazes de melhorar a classe funcional NYHA do paciente, ao mesmo tempo que promove diminuição da necessidade de terapias invasivas.

Conclusões: O resultado da análise de custo de sequência de tratamento de câncer de ovário HRD/BRCAwt apresentou um custo total estimado de BRL 1.272.237, com 2,8 anos de vida livre de progressão. Essa análise contribui no entendimento dos custos e da eficácia esperada com o uso da terapia de manutenção de niraparibe em 1L e bevacizumabe em 2L em um horizonte temporal de cinco anos.

Objective: To estimate the cost of the treatment sequence, considering the maintenance therapies niraparib and bevacizumab, respectively, as maintenance therapies in 1L and 2L for patients with epithelial ovarian cancer with homologous recombination deficiency (HRD) and BRCA wild-type (BRCAwt) over a 5-year time horizon from the perspective of the Brazilian supplementary health system. Methods: A partitioned survival model was developed with three health state transitions, considering the following regimens in the 1L and 2L, respectively: carboplatin + paclitaxel followed by maintenance therapy with niraparib; carboplatin + gemcitabine + bevacizumab followed by the continuation of bevacizumab. The product's label and progression-free survival curves from the respective pivotal studies in each of the therapeutic lines were used in the analysis and the cost of treatment was calculated using as a reference the official CMED drug price list from April 2023. Results: The cost in 1L and 2L was BRL 868,830 and BRL 403,407, totaling BRL 1,272,237 over a 5-year period, with 2.28 and 0.52 years of progression-free survival, respectively in 1L and 2L, with a total of 2.8 years. Conclusions: The result of the analysis of the cost of the treatment sequence of ovarian cancer HRD/BRCAwt presented an estimated total cost of 1,272,237 with 2.8 year of progression-free survival. This analysis contributes to understand the expected cost and effectiveness with the use of maintenance therapy niraparib in 1L and bevacizumab in 2L over a 5-year time horizon.

Desafios e perspectivas da saúde suplementar: notas sobre o estado da arte na jurisprudência do Supremo Tribunal Federal e do Superior Tribunal de Justiça / Challenges and perspectives of supplementary health: notes on the state of the art in the jurisprudence of the Supreme Court and the Superior Court of Justice / Retos y perspectivas de la salud suplementaria: notas sobre el estado del arte en la jurisprudencia del Supremo Tribunal Federal y del Superior Tribunal de Justicia

Objetivo: analisar as perspectivas e os desafios na concretização do dever de garantir a mais completa assistência no campo da saúde suplementar. Metodologia: pesquisa qualitativa de natureza descritiva, que analisou acervo documental composto pelos principais diplomas legais relacionados ao campo da saúde suplementar e a evolução da jurisprudência do Supremo Tribunal Federal e do Superior Tribunal de Justiça nessa área, notadamente sobre o fornecimento de medicamentos não registrados pela Anvisa ou uso off label de remédios registrados, e acerca da taxatividade mitigada do rol da ANS. Resultados: as avenças firmadas entre os planos de saúde e os beneficiários configuram relação contratual na qual o consumidor é a parte vulnerável, mas, por outro lado, detém informações que não são de conhecimento da operadora. Esta, por sua vez, detém conhecimentos técnicos sobre moléstias e tratamentos muito além da compreensão de um consumidor comum. Nesse mercado, em que predomina a assimetria informacional, avulta a importância da firme atuação da agência reguladora, entidade capaz de equilibrar o sistema, dando tratamento uniforme a questões que devem ser globalmente consideradas, tendo em vista a massa de consumidores de planos de saúde, levando em conta as especificidades de cada tipo de contrato, individual ou coletivo, anterior ou posterior à Lei nº 9.656/1998.Conclusão: a atuação do Legislativo deve levar em conta o delicado equilíbrio entre as necessidades e as possibilidades, bem como as características inerentes ao caráter privado da prestação, de forma suplementar, de serviços de natureza pública, ao passo que a intervenção do Judiciário para infirmar decisões da agência reguladora justifica-se apenas em casos de clara ilegalidade e, sobretudo, deve levar em conta a globalidade do sistema regulado, o que nem sempre é facilmente perceptível à vista de casos individualmente considerados.

Objective: to analyze the perspectives and challenges in the realization of the duty to guarantee the most complete assistance in the field of supplementary health. Methods: qualitative research of descriptive nature that analyzed documentary collection composed of the main legal diplomas related to the field of supplementary health and the evolution of jurisprudence of the Supreme Court and the Superior Court of Justice in this area, especially about the supply of medicines not registered by Anvisa or off label use of registered medicines, and about the mitigated taxation of the ANS list. Results: the agreements signed between the health plans and the beneficiaries configure contractual relationship in which the consumer is the vulnerable party, but, on the other hand, holds information that is not known to the operator. This, in turn, has technical knowledge about diseases and treatments far beyond the understanding of a common consumer. In this market, in which information asymmetry predominates, the importance of the firm action of the regulatory agency, an entity capable of balancing the system, giving uniform treatment to issues that should be considered globally, in view of the mass of consumers of health plans, taking into account the specificities of each type of contract, individual or collective, before or after Bill9, 656/1998. Conclusion: the Legislative action must take into account the delicate balance between needs and possibilities, as well as the characteristics inherent in the private character of the provision, in a supplementary nature, of services of a public nature, whereas intervention by the judiciary to rule against decisions of the regulatory agency is justified only in cases of clear illegality and, above all, must take into account the whole of the regulated system, which is not always easily perceived in view of individual cases.

Objetivo: analizar las perspectivas y los desafíos en la realización del deber de garantizar la más completa asistencia en el campo de la salud complementaria. Metodología: investigación cualitativa de naturaleza descriptiva que analizó acervo documental compuesto por los principales diplomas legales relacionados al campo de la salud complementaria y la evolución de la jurisprudencia del Supremo Tribunal Federal y del Superior Tribunal de Justicia en esa área, especialmente sobre el suministro de medicamentos no registrados por la Anvisa o uso fuera de etiqueta de remedios registrados, y acerca de la taxactividad mitigada del rol de la ANS. Resultados: las avencias firmadas entre los planes de salud y los beneficiarios configuran relación contractual en la cual el consumidor es la parte vulnerable, pero, por otro lado, posee informaciones que no son de conocimiento del operador. Ésta, a su vez, posee conocimientos técnicos sobre enfermedades y tratamientos mucho más allá de la comprensión de un consumidor común. En este mercado, en el que predomina la asimetría informacional, la importancia de la firme actuación de la agencia reguladora, capaz de equilibrar el sistema, dando tratamiento uniforme a cuestiones que deben ser consideradas globalmente, teniendo en cuenta las especificidades de cada tipo de contrato, individual o colectivo, anterior o posterior a la Ley 9.656/1998. Conclusión: la actuación del Legislativo debe tener en cuenta el delicado equilibrio entre las necesidades y las posibilidades, así como las características inherentes al carácter privado de la prestación, en carácter suplementario, de servicios de carácter público, mientras que la intervención del poder judicial para invalidar las decisiones de la agencia reguladora sólo se justifica en casos de clara ilegalidad y, sobre todo, debe tener en cuenta la totalidad del sistema regulado, lo que no siempre es fácilmente perceptible a la vista de casos individuales considerados.

Effectiveness and safety of tocilizumab for COVID-19: a systematic review and meta-analysis of randomized clinical trials

ABSTRACT BACKGROUND: Tocilizumab is an anti-human interleukin 6 receptor monoclonal antibody that has been used to treat coronavirus disease 2019 (COVID-19). However, there is no consensus on its efficacy for the treatment of COVID-19. OBJECTIVE: To evaluate the effectiveness and safety of tocilizumab for treating COVID-19. DESIGN AND SETTING: Systematic Review of randomized controlled trials (RCTs), Universidade Federal de São Paulo (UNIFESP), São Paulo (SP), Brazil. METHODS: We searched MEDLINE via PubMed, EMBASE, CENTRAL, and IBECS for RCTs published up to March 2021. Two authors selected studies and assessed the risk of bias and the certainty of the evidence following Cochrane Recommendations. RESULTS: Eight RCTs with 6,139 participants were included. We were not able to find differences between using tocilizumab compared to standard care on mortality in hospitalized patients with COVID-19 (risk ratio (RR) 0.97, 95% confidence interval (CI) 0.84 to 1.13; 8 trials; 5,950 participants; low-certainty evidence). However, hospitalized patients under tocilizumab plus standard care treatment seemed to present a significantly lower risk of needing mechanical ventilation (risk ratio = 0.78; 95% CI 0.64−0.94 moderate-certainty of evidence). CONCLUSIONS: To date, the best evidence available shows no difference between using tocilizumab plus standard care compared to standard care alone for reducing mortality in patients with COVID-19. However, as a finding with a practical implication, the use of tocilizumab in association to standard care probably reduces the risk of progressing to mechanical ventilation in those patients.

Aspectos histológicos, genéticos y moleculares de las lesiones preneoplásicas de la mucosa gástrica / Histological, genetic and molecular aspects of preneoplastic lesions of the gastric mucosa

Siendo el cáncer gástrico la 3ª causa de muerte por cáncer en Chile, y existiendo estrategias de tamizaje consistentes en pesquisa de lesiones preneoplásicas de la mucosa gástrica, es relevante conocer los aspectos genéticos y moleculares que puedan ser aplicados, en la optimización de dichas estrategias a grupos de mayor riesgo. El objetivo de este manuscrito fue revisar la evidencia actual en los aspectos señalados, y de la inmunohistoquímica de 4 marcadores (p53, CDX2, MUC2 y S100A9) en la mucosa gástrica normal y en las lesiones preneoplásicas de la misma.

SUMMARY: Since gastric cancer is the 3rd leading cause of death from cancer in Chile, and there are screening strategies consisting of screening for preneoplastic lesions of the gastric mucosa, it is important to know certain genetic and molecular aspects that can be applied in optimizing these strategies for higher risk groups. The aim of this manuscript was to review the current evidence on the aforementioned aspects, and on the immunohistochemistry of 4 markers (p53, CDX2, MUC2 and S100A9) in normal gastric mucosa and in its preneoplastic lesions.

Forage Supplementation Feeding of Lactating Merino Ewes in Dry Season at the Foothills Agro-ecological Zone in Lesotho

A farmer-participatory research, which lasted for seven weeks, was carried out at Machache, in the Foothills Agro-Ecological Zone of Lesotho to examine the effect of forage based diets supplementary feeding on the performance response and milk quality of lactating ewes during dry lambing season. A total of 270 lactating merino ewes were randomly distributed among four dietary treatments: basal diet (T1) which was the range land pasture used as control, cereal forage based diet (T2), leguminous forage based diet (T3) and mixed forage based diet (T4). The feed value of the supplementary diets T2 (4.70% CP and 9.94MJ/kg ME), T3 (12.31% CP and 10.27 MJ/kg ME), T4 (11.90% CP and 10.47 MJ/kg ME)] was superior to that of the range land pasture T1 (2.80% CP and 8.61MJ/kg ME). Ewes on forage supplemented diets performed significantly (P<0.05) better than the control group in feed intake, live body weight and live weight change. The milk quality evaluation showed that solids-non-fat (SNF), protein and lactose were highly significant (P<0.05) for T3 and T4 than T1 and T2 which had high milk fat. The study revealed that diets T1 and T2 lacked the nutritional capacity to meet the nutrient requirements of lactating ewes as evidenced by slight body weight improvement. It is concluded that supplementary diets T3 (leguminous forage based diet) and T4 (mixed forage based diet) contained adequate nutrients that can meet the requirement of lactating ewes during dry lambing season. This was verified by high voluntary feed intake and good nutrients utilization as resulted by improving of body weight and high milk quality response of lactating ewes.

Radiocirugía estereotáxica por gamma knife en un paciente con cavernoma cerebral y síndrome de Evans

El cavernoma cerebral es una malformación vascular de diagnóstico infrecuente. Se define como una malformación a nivel de la vasculatura microcerebral que, dependiendo a la ubicación y si existe la posibilidad de ruptura, conlleva a una emergencia que puede terminar en la muerte del paciente. En esta oportunidad se reporta el caso de un paciente con cavernoma cerebral asociado al síndrome de Evans. Se decide manejo quirúrgico de la lesión por aumento de intensidad de cefalea e intolerancia oral. Dada la coexistencia del Síndrome de Evans y la alta tasa de morbimortalidad es que se decide manejo quirúrgico mediante radiocirugía estereotáxica con gamma knife. El uso de dosis de margen bajo para tratamiento con gamma knife para uso en cavernomas cerebrales produce un manejo controlado para sintomatología de convulsiones y mejor expectativa de calidad de vida.

Cerebral cavernoma is an infrequently diagnosed vascular malformation. It is defined as a malformation at the level of the microcerebral vasculature that, depending on the location and if there is a possibility of rupture, leads to an emergency that can end in the death of the patient. On this occasion, we report a case of a patient with cerebral cavernoma associated with Evans syndrome. Surgical management of the lesion was decided due to increased intensity of headache and oral intolerance. Given the coexistence of Evans Syndrome and the high rate of morbidity and mortality, surgical management was decided by stereotaxic radiosurgery with a gamma knife. The use of low-margin doses for treatment with gamma knife for use in brain cavernomas produces controlled management for seizure symptoms and better quality of life expectancy.

WANG Xinlu's Experience in Treating Metabolic Syndrome based on “Blood Turbidity” / 中医杂志

This paper summarized professor WANG Xinlu's experience in treating metabolic syndrome （MS） based on the “blood turbidity” theory. It is believed that blood turbidity is the key pathological factor for the onset of MS. Blood turbidity accumulates internally， and the zang-fu （脏腑） organs become useless， leading to MS. With long-term blood turbidity， phlegm and stasis are cemented， and the condition is worsened， having changed syndromesfrequently. In clinical practice， the basic treatment method is to clear and dissolve blood turbidity， taking self-prepared Modified Huazhuo Xingxue Decoction （加味化浊行血汤） as the basic formula， and flexibly modifying it according to different stages and manifestations of the disease. Simultaneously， supplementary modern medicines are used to treat abnormal indicators of western medicine.

Knowledge, attitude and perception of mothers of under-five towards vaccination during supplementary immunization activities in Ibadan North-West Local Government Area, Ibadan, Oyo State, Nigeria

Supplementary immunization activities campaigns provide children with an additional dose of vaccine and deliver other interventions. However, there is dearth of information on knowledge, attitude and perception of mothers of under-five towards vaccination during supplementary immunization activities. A descriptive cross-sectional study which employed multistage sampling technique was designed to fill this gap. Four wards were randomly selected from eleven wards in Ibadan North-West Local Government Area and houses were enumerated from the selected wards, systematic random sampling was used to select houses and then respondents. A semi-structured interviewer administered questionnaire was used to elicit information on three hundred and five respondents. Knowledge scores of ≤4, 5-8, and ≥ 9 were rated poor, fair and good, respectively. Attitude scores of ≤5 and >5 was rated negative and positive attitude, respectively while perception scores ≤4 and >4 were rated negative and positive perception, respectively. Data was analyzed with SPSS version 25 using descriptive statistics and Chi-square test at 5% level of significance. The mean age of respondents was 30.6±6.1years, the highest level of education for most (68.5%) was secondary school. Their mean parity and number of under-five were 2.5±1.4 and 1.2±0.4, respectively. Knowledge was generally poor, more than half (53.1%) had poor knowledge, majority (88.2%) have positive attitude while 84.6% have a positive perception. One-fourth (24.6%) and one-fifth are of the opinion that frequent vaccination will make the vaccine ineffective and overload immune system, respectively. There was generally poor knowledge of supplementary immunizations and mothers need to be educated on the importance.
