Reflections on nomenclature and expansion of surgical indications for endoscopic spinal surgery / 国际外科学杂志

In recent years, with the development and maturity of endoscopic technique, endoscopic spinal surgery represented by water media and optical rigid endoscope has been widely used in the treatment of many disorders in the cervical, thoracic and lumbar spine. Endoscopic spinal surgery shows similar clinical effects as traditional open surgery or other minimally invasive procedures, and is favored by spinal surgeons due to its advantages of less trauma and rapid recovery after surgery. However, the large-scale application of endoscopic technique brings problems such as non-standard nomenclature and unreasonable indications. Therefore, this article will summarize the surgical nomenclature and indications of endoscopic spinal surgery, in order to provide a reference for spinal surgeons to understand and apply endoscopic technology reasonably.

ICP-MS establishes blood lead reference method expected to improve detection accuracy / 中华检验医学杂志

Lead poisoning severely threatens human health with its cumulation and durability in the body. The analysis of lead in blood is vital for screening, diagnosis, treatment, and prognostication of lead poisoning and for indirectly monitoring the level of lead in the environment. Although the detection programs are available throughout our country, the accuracy and comparability of the results cannot meet the expectation. A variety of factors can affect the accuracy of blood lead testing. To promote the application of blood lead analysis in clinical trials and reduce the bias of results, a better reference system for blood lead analysis should be established to evaluate the accuracy of traditional methods, promote the standardization of blood lead analysis and achieve accurate blood lead testing.

Research progress on standardized clinical outcome of peritoneal dialysis / 中华肾脏病杂志

As a home treatment and economical and practical treatment mode, peritoneal dialysis (PD) is an effective renal replacement therapy for end-stage kidney disease. The number of PD patients in the world is increasing, and prognosis has been significantly improved. However, compared with the general population, the quality of life of PD patients is not satisfactory, and the disease burden is still very high. There is significant heterogeneity in the reports of clinical outcomes of PD in different countries and regions. The heterogeneity seriously affects the validity of clinical research evidence and the continuous improvement of the quality of PD centers. New progress has been made in the study of standardized clinical outcome of PD in recent years. The article reviews the heterogeneity of PD clinical outcome report, standardized clinical outcome classification and core outcome to standardize the report of PD clinical outcome, improve the clinical research quality and management level of PD, and finally improve the prognosis of patients.

Translation and Validation of the Boston Technical Performance Score in a Developing Country

Abstract Introduction: The Technical Performance Score (TPS) was developed and subsequently refined at the Boston Children's Hospital. Our objective was to translate and validate its application in a developing country. Methods: The score was translated into the Portuguese language and approved by the TPS authors. Subsequently, we studied 1,030 surgeries from June 2018 to October 2020. TPS could not be assigned in 58 surgeries, and these were excluded. Surgical risk score was evaluated using Risk Adjustment in Congenital Heart Surgery (or RACHS-1). The impact of TPS on outcomes was studied using multivariable linear and logistic regression adjusting for important perioperative covariates. Results: Median age and weight were 2.2 (interquartile range [IQR] = 0.5-13) years and 10.8 (IQR = 5.6-40) kilograms, respectively. In-hospital mortality was 6.58% (n=64), and postoperative complications occurred in 19.7% (n=192) of the cases. TPS was categorized as 1 in 359 cases (37%), 2 in 464 (47.7%), and 3 in 149 (15.3%). Multivariable analysis identified TPS class 3 as a predictor of longer hospital stay (coefficient: 6.6; standard error: 2.2; P=0.003), higher number of complications (odds ratio [OR]: 1.84; 95% confidence interval [CI]: 1.1-3; P=0.01), and higher mortality (OR: 3.2; 95% CI: 1.4-7; P=0.004). Conclusion: TPS translated into the Portuguese language was validated and showed to be able to predict higher mortality, complication rate, and prolonged postoperative hospital stay in a high-volume Latin-American congenital heart surgery program. TPS is generalizable and can be used as an outcome assessment tool in resource diverse settings.

La trazabilidad en el sistema logístico de medicamentos en Cuba y el uso de las tecnologías de auto-identificación / Traceability in the logistics system of medicines in Cuba, use of auto-identification

La trazabilidad es la capacidad para rastrear la historia, aplicación o ubicación de un objeto bajo consideración. En el ámbito farmacéutico, el rastreo y seguimiento de los medicamentos, incluyendo las vacunas y otros medicamentos biológicos, a lo largo de la cadena de suministro constituye un requisito obligatorio establecido por las autoridades sanitarias a nivel internacional, que se exige en mayor o menor magnitud en las reglamentaciones vigentes. En este artículo se analiza el sistema de codificación y clasificación en el sector de la salud y su estado actual en la cadena de suministro de medicamentos de Cuba. Se presenta un procedimiento para la implementación de las tecnologías de auto-identificación e intercambio electrónico de datos, mediante el uso de GS1 en el sistema de codificación y clasificación empleado en el sector de salud, que permita la trazabilidad en toda la cadena de suministro en Cuba(AU)

Traceability is the capability to track the history, application or location of an object under consideration. In the pharmaceutical field, the tracking and monitoring of medicines, including vaccines and other biological medicines, along the supply chain constitutes a mandatory requirement established by the sanitary authorities at an international level, which is demanded to a greater or lesser extent in the regulations in force. This research was carried out involving different links in the drug supply chain in Cuba, ranging from drug suppliers, drug distribution company, to healthcare centers and pharmacies. An analysis is carried out on the current coding and classification system, detecting the ineffectiveness of the identification of the drugs as the main deficiency. A procedure is proposed for the implementation of the auto-identification and electronic data interchange technologies using GS1 in the coding and classification system used in the health sector that allows traceability throughout the supply chain in Cuba(AU)

Adherencia a las recomendaciones de tromboprofilaxis post-cesárea: estudio de corte transversal / Compliance with post-cesarean section thromboprophylaxis recommendations. A cross sectional study in 233 women

Background: Cesarean section increases four times the risk of venous thromboembolism compared to vaginal delivery. The Royal College of Obstetricians and Gynecologists guidelines are used at our service. A written alert was designed to stratify patients at high, intermediate or low risk making a suggestion for thromboprophylaxis. Aim: To assess the compliance with the guidelines and to evaluate the impact of a written alert in the thromboprophylaxis compliance in women subjected to caesarean section. Patients and Methods: Review of medical records of 233 women aged 19 to 32 years, subjected to a caesarean section in a Gynecology Service, between 2016-2017. Results: Compliance with recommendations was observed in 29% of patients (68/233), 86% in the low-risk group, 26% in the intermediate risk group and 100% in the high risk group. In 41/233 (18%) of patients, a written alert was included in the medical record. Compliance with recommendations in the presence of the written alert was 61% (25/41 women) compared to 22% (43/192) in those lacking the alert (p < 0.01). In women whose emergency caesarean section was the only risk factor, the compliance with the recommendation was 8%, compared with 30% among those who had at least one thrombotic risk factor associated with caesarean section (p < 0.01). Conclusions: In this cross-sectional study, we observed a low compliance with thromboprophylaxis guidelines in cesarean women. We observed that the use of a written alert improved the compliance with thromboprophylaxis.

The proposed percentiles may be useful to assess MC and could be included and adapted as performance indicators in physical education

¿Por qué continuamos transfundiendo dos unidades de sangre a la vez si con una sola podría ser suficiente? / Why do we keep transfusing two units of blood at the same time if just one could be enough? / Por que continuamos a transfundir duas unidades de sangue ao mesmo tempo se apenas uma pode ser o suficiente?

Resumen: La transfusión de sangre ha sido identificada como uno de los procedimientos médicos más sobreutilizados en pacientes hospitalizados. Una estrategia que permitiría reducir la exposición de los pacientes a la sangre es a través de la implementación de una política de transfusión de una sola unidad, en lugar de dos, para pacientes estables, sin hemorragia y con anemia sintomática. La decisión de transfundir sangre es compleja y depende de varios factores, además, los riesgos de la transfusión se deben sopesar contra los beneficios esperados. La transfusión de dos unidades de sangre a la vez ya no se considera una forma de tratamiento "estándar" para pacientes anémicos sin sangrado activo. Existe una gran oportunidad para reducir el uso excesivo de la transfusión y fomentar las transfusiones de una sola unidad.

Summary: Blood transfusion has been identified as one of the most overused medical procedures in hospitalized patients. One strategy that would reduce the exposure of patients to blood is through the implementation of a single-unit regime for stable patients without bleeding and with symptomatic anemia. The decision to transfuse blood is complex and depends on several factors, in addition, the risks of transfusion must be weighed against the expected benefits. Transfusion of two units of blood at the same time is no longer considered a "standard" form of treatment for anemic patients without active bleeding. There is a great opportunity to reduce the overuse of transfusion and encourage single-unit transfusions.

Resumo: A transfusão de sangue foi identificada como um dos procedimentos médicos usados de mais em pacientes hospitalizados. Uma estratégia que reduziria a exposição dos pacientes ao sangue é por meio da implantação de uma política transfusional de unidade única para pacientes estáveis, sem sangramento e com anemia sintomática. A decisão de transfundir sangue é complexa e depende de vários fatores, além disso, os riscos da transfusão devem ser analisados em relação aos benefícios esperados. A transfusão de duas unidades de sangue ao mesmo tempo não é mais considerada uma forma "padrão" de tratamento para pacientes anêmicos sem sangramento ativo. Há uma grande oportunidade de reduzir o uso excessivo de transfusões e incentivar as transfusões de uma única unidade.

Geographical origin of chronic Chagas disease patients in Brazil impacts the performance of commercial tests for anti-T. cruzi IgG

BACKGROUND Chagas disease, caused by Trypanosoma cruzi, affects nearly six million people worldwide. Various serological tests have been developed for its diagnosis. OBJECTIVE Examine the performance of a set of commercial immunological assays in relation to the geographical origin of the patient sample comparing four states of Brazil: Amazonas (AM), Mato Grosso do Sul (MS), Minas Gerais (MG) and Piauí (PI). METHODS Seven immunoassays were employed to detect anti-T. cruzi IgG antibodies in 379 patient samples that had been previously diagnosed using the two-step protocol required by the Brazilian Ministry of Health. FINDINGS A significant variation in the percent reactive was calculated for the samples from AM and MS, while the PI and MG showed a significant variation in the percent non-reactive. The average reactivity index was significantly higher for samples from the states of PI and MG states than AM and MS. MAIN CONCLUSIONS All tests presented a satisfactory performance overall. Yet, variations were observed that were associated to the region of origin of the samples. Our analyses suggest that future evaluations of immunoassays should include a sampling of sera from regions where the test will be applied in addition to the available International Biological Reference Standards.
