Evaluation of the consistency of four hematology systems / 中华检验医学杂志

Objective:To provide consistent data basis for the application of reference intervals for children blood cell analysis in different testing systems.Methods:According to the requirements of American Institute for Clinical and Laboratory Standardization (CLSI) EP9-A3 document, 45 samples were collected and Sysmex XN20-A1 were used as reference system. Beckman DxH800, Siemens ADVIA 2120i, and Mindray BC5310 were comparison systems. Complete blood count and leukocyte classification were performed by four systems. The outliers of the detection results were tested by the generalized extreme student deviate (ESD) method. An optimal regression model was selected by scatter diagram, deviation diagram and frequency distribution diagram, which was used to fit the regression equation and calculate the deviation at the medical decision level and reference interval. The acceptable range for blood count deviation was cited from the Analytical Quality Specifications for Routine Tests in Clinical Hematology. The acceptable range for leukocyte classification was based on the EQA program of Royal College of Pathologists of Australasia (RCPA).Results:After the outliers were deleted, the scatter plot showed a linear relationship between the reference system and the three comparison systems. The deviation plot showed that the differences were variable. Deming regression or Passing-Bablok regression was selected according to the data distribution. The determination coefficient R2 of reference system and three comparison systems ranged from 0.95 to 0.99 in blood count and leukocyte classification. At the upper and lower limits of the reference interval, the deviations between XN-20A1 and ADVIA 2120 system were all acceptable, except for MONO# at 0.12×10 9/L. The deviations of all parameters at medical decision level were within acceptable ranges. The lower limit of PLT is partially unacceptable at the level of medical decision related to treatment and prognosis. Conclusions:The results of complete blood count and leukocyte classification in reference system and the comparison system had good consistency within the children′s reference interval. Our study provided a scientific basis for the feasibility of adopting a unified reference interval for different detection systems.

Noninvasive hemoglobin monitoring in clinical trials: a systematic review and meta-analysis / Monitorização não invasiva da hemoglobina em ensaios clínicos: uma revisão sistemática e metanálise

Abstract Background and objectives: The measurement of hemoglobin concentration (Hb) by co-oximetry is an innovative technique that offers efficiency and agility in the processing of information regarding the measurement of Hb obtained through continuous, non-invasive and rapid monitoring. Because of this attribute, it avoids unnecessary exposures of the patient to invasive procedures by allowing a reduction in the number of blood samples for evaluation and other unnecessary therapies. It also helps to make decisions about the need for transfusion and how to handle it. The objective of this study is to compare the performance offered to obtain Hb values between the Masimo Corporation (Irvine, CA, USA) instrument and the standard gold tool (laboratory examination). Contents: The study corresponds to a systematic review followed by meta-analysis, which included fully registered full-text clinical trials published from 1990 to 2018. PubMed, Cochrane, Medline, Embase and Web of Science databases were investigated. The mean overall difference found between the non-invasive and invasive methods of hemoglobin monitoring was 0.23 (95% CI -0.16, 0.62), that is, it did not present statistical significance (p = 0.250). The results of the analysis of heterogeneity within and between the studies indicated high levels of inconsistency (Q = 461.63, p < 0.0001, I2 = 98%), method for Hb values. Conclusions: Although the mean difference between noninvasive measurements of Hb and the gold standard method is small, the co-oximeter can be used as a non-invasive "trend" monitor in detecting unexpected responses at Hb levels.

Resumo Justificativa: A medida da concentração de hemoglobina (Hb)por co-oximetria é uma técnica inovadora que oferece eficiência e agilidade no processamento das informações referentes à medida da concentração de hemoglobina obtida por meio de monitorização contínua, não-invasiva e rápida. Por conta desse atributo, evita exposições desnecessárias do paciente a procedimentos invasivos ao possibilitar redução da quantidade de amostras sanguíneas para avaliação e de outras terapêuticas desnecessárias. Além disso, auxilia a tomada de decisões quanto à necessidade de transfusão e quanto ao manejo da mesma. Objetivo: Comparar o desempenho oferecido para a obtenção dos valores de concentração de hemoglobina entre medida não invasiva da Hb e a ferramenta padrão ouro (exame laboratorial). Conteúdo: O estudo corresponde a uma revisão sistemática seguida de metanálise que incluiu ensaios clínicos devidamente registrados com texto completo, publicados a partir de 1990 até 2018. Foram investigadas as bases de dados PubMed, Cochrane, Medline, Embase e Web Of Science. A diferença média global encontrada entre os métodos não invasivo e invasivo de monitorização da hemoglobina foi de 0,23 (95% IC -0,16; 0,62), ou seja, não apresentou significância estatística (p = 0,250). Os resultados da análise de heterogeneidade dentro e entre os estudos, apontou níveis elevados de inconsistência (Q = 461,63, p< 0,0001, I2 = 98%). Conclusão: Embora a diferença média entre as medidas não invasivas da Hb e o método padrão ouro sejam pequenas, o co-oxímetro pode ser utilizado como um monitor não invasivo de "tendência" na detecção de alterações inesperadas nos níveis de Hb.

Irisin and troponin I expression in dialysis patients submitted to remote ischemic preconditioning: a pilot study / Expressão de irisina e troponina I em pacientes em diálise submetidos a pré-condicionamento isquêmico remoto: um estudo piloto

ABSTRACT Background: Renal replacement therapy continues to be related to high hospitalization rates and poor quality of life. All-cause morbidity and mortality in renal replacement therapy in greater than 20% per year, being 44 times greater when diabetes is present, and over 10 times that of the general population. Regardless of treatment, the 5-year survival is 40%, surpassing many types of cancers. Irisin is a hormone that converts white adipose tissue into beige adipose tissue, aggregating positive effects like fat mass control, glucose tolerance, insulin resistance, prevention of muscle loss, and reduction in systemic inflammation. Objectives: To determine the serum levels of troponin I in hemodialysis patients submitted to remote ischemic preconditioning (RIPC) associated with irisin expression. Methods: This was a prospective, randomized, double-blind clinical trial with patients with chronic kidney disease submitted to hemodialysis for a 6-month period. Troponin I, IL-6, urea, TNF-α, and creatinine levels were determined from blood samples. The expressions of irisin, thioredoxin, Nf-kb, GPX4, selenoprotein and GADPH were also evaluated by RT-PCR. Results: Samples from 14 hypertensive patients were analyzed, 9 (64.3%) of whom were type 2 diabetics, aged 44-64 years, and 50% of each sex. The difference between pre- and post-intervention levels of troponin I was not significant. No differences were verified between the RIPC and control groups, except for IL-6, although a significant correlation was observed between irisin and troponin I. Conclusion: Remote ischemic preconditioning did not modify irisin or troponin I expression, independent of the time of collection.

RESUMO Introdução: A terapia de substituição renal continua associada a altas taxas de hospitalização e baixa qualidade de vida. A morbimortalidade por todas as causas na terapia de substituição renal é superior a 20% ao ano, sendo 44 vezes maior quando a diabetes está presente e mais de 10 vezes a da população em geral. Independentemente do tratamento, a sobrevida em 5 anos é de 40%, superando muitos tipos de câncer. A irisina é um hormônio que converte tecido adiposo branco em tecido adiposo bege, agregando efeitos positivos como o controle de massa gorda, tolerância à glicose, resistência à insulina, prevenção de perda muscular e redução da inflamação sistêmica. Objetivos: Determinar os níveis séricos de troponina I em pacientes em hemodiálise submetidos ao pré-condicionamento isquêmico remoto (PCIR) associado à expressão da irisina. Métodos: Estudo clínico prospectivo, randomizado, duplo-cego, com pacientes com doença renal crônica submetidos à hemodiálise por um período de 6 meses. Os níveis de troponina I, IL-6, uréia, TNF-α e creatinina foram determinados a partir de amostras de sangue. As expressões de irisina, tioredoxina, Nf-kb, GPX4, selenoproteína e GADPH foram também avaliadas por RT-PCR. Resultados: Foram analisadas amostras de 14 pacientes hipertensos, 9 (64,3%) dos quais eram diabéticos tipo 2, com idades entre 44 e 64 anos e 50% de cada gênero. A diferença entre os níveis pré e pós-intervenção de troponina I não foi significativa. Não houve diferenças entre os grupos PCIR e controle, exceto pela IL-6, embora tenha sido observada correlação significativa entre irisina e troponina I. Conclusão: O pré-condicionamento isquêmico remoto não modificou a expressão de irisina ou troponina I, independentemente do tempo de coleta.

Además, debido a la especificidad de la modalidad, sus practicantes tienen bajo porcentaje de grasa corporal.

PULMONARY AND BIOCHEMICAL CHARACTERISTICS OF SMOKER AND NON-SMOKER MODERN DANCERS / CARACTERISTICAS PULMONARES E BIOQUÍMICAS DE DANÇARINOS MODERNOS FUMANTES E NÃO-FUMANTES / CARACTERÍSTICAS PULMOMARES Y BIOQUÍMICAS DE BAILARINAS MODERNAS FUMADORAS Y NO FUMADORAS

ABSTRACT Introduction: Although the harmful effects of smoking on the cardiovascular and respiratory systems have been established for a long time, the effect on physiological and physical parameters in modern female dancers is not well documented. Objective: To determine differences in selected pulmonary functions, biochemical parameters, and body composition in female smoker and non-smoker modern dancers who are university or graduate students. Methods: A total of twenty-two female modern dancers (mean age of 24.6 ± 4.3 years), who were non-smokers (n = 11) and smokers (n = 11), voluntarily participated in the study. The smokers had been smoking 1 to 20 cigarettes per day for an average period of seven years. The pulmonary function test Mir Spirobank Spirometer, (Italy) was applied; selected biochemical parameters were tested, and various anthropometric measurements (height, weight and seven skinfold thickness) were performed. The results of body composition were evaluated using Jackson-Pollock equations. Intergroup comparisons were performed using the Mann-Whitney U test. Result: No significant differences were found between smoker and non-smoker dancers in terms of body composition (body fat, % body fat, lean body fat) and selected biochemical parameters (p > 0.05). However, non-smokers had prediction values of forced expiratory volume during the first second (FEV1) and peak expiratory flow (PEF) significantly better (p < 0.05). The effect of smoking on the performance of female modern dancers should be examined in a longitudinal study, with a higher number of participants. Conclusion: It was observed that smoking reduces lung pulmonary capacity at a certain rate, although the biochemical parameters and body composition of the female smoker and non-smoker dancers were similar.

RESUMO Introdução: Embora os efeitos nocivos do fumo nos sistemas cardiovascular e respiratório tenham sido estabelecidos há muito, o efeito sobre os parâmetros fisiológicos e físicos em bailarinas de dança moderna não foi bem documentado ainda. Objetivo: Determinar as diferenças em funções pulmonares selecionadas, parâmetros bioquímicos e composição corporal em bailarinas de dança moderna fumadoras e não-fumadoras, universitárias e pós-universitárias. Métodos: Vinte e duas bailarinas de dança moderna (média de idade de 24,6 ± 4,3 anos), não fumantes (n = 11) e fumantes (n = 11), participaram voluntariamente no estudo. As fumantesconsumiram de 1 a 20 cigarros por dia durante uma média de sete anos. Foi aplicado o teste funcional pulmonar Mir Spirobank Spirometer, (Itália), alguns parâmetros biomédicos selecionados foram testados e foram realizadas várias medições antropométricas (altura, peso e sete espessuras de pregas cutâneas). Os resultados da composição corporal foram avaliados usando equações Jackson-Pollock. As comparações intergrupo foram realizadas usando o teste "U" de Mann-Whitney. Resultado: Não foram encontradas diferenças significativas entre as bailarinas fumantes e não fumantes quanto à composição corporal (gordura corporal, % massa gorda, massa corporal magra) e nos parâmetros bioquímicos selecionados (p > 0,05). No entanto, as não fumantes tinham valores de predição do volume expiratório forçado no primeiro segundo (VEF1) e pico de fluxo expiratório (PFE) significativamente melhores (p < 0,05). O efeito do tabagismo no desempenho de bailarinas de dança moderna deveria ser examinado num estudo longitudinal, com um maior número de participantes. Conclusão: Foi observado que o fumo reduz a capacidade pulmonar a uma certa taxa, embora os padrões bioquímicos e a composição corporal das bailarinas fumantes e não fumantes fossem semelhantes.

Parameters of Calcium Metabolism Fluctuated during Initiation or Changing of Antipsychotic Drugs

OBJECTIVE: Serum parameters of calcium homeostasis were measured based on previously published evidence linking osteoporotic fractures and/or bone/mineral loss with antipsychotics. METHODS: Prospective, four-week, time-series trial was conducted and study population consisted of patients of both genders, aged 35-85 years, admitted within the routine practice, with acute psychotic symptoms, to whom an antipsychotic drug was either introduced or substituted. Serial measurements of serum calcium, phosphorous, magnesium, 25(OH)D, parathyroid hormone, calcitonin, osteocalcin and C-telopeptide were made from patient venous blood samples. RESULTS: Calcium serum concentrations significantly decreased from baseline to the fourth week (2.42+/-0.12 vs. 2.33+/-0.16 mmol/L, p=0.022, n=25). The mean of all calcemia changes from the baseline was -2.6+/-5.7% (-24.1 to 7.7) with more decreases than increases (78 vs. 49, p=0.010) and more patents having negative sum of calcemia changes from baseline (n=28) than positive ones (n=10) (p=0.004). There were simultaneous falls of calcium and magnesium from baseline (63/15 vs. 23/26, p<0.001; OR=4.75, 95% CI 2.14-10.51), phosphorous (45/33 vs. 9/40, p<0.001; 6.06, 2.59-14.20) and 25(OH)D concentrations (57/21 vs. 13/35, p<0.001; 7.31, 3.25-16.42), respectively. Calcemia positively correlated with magnesemia, phosphatemia and 25(OH)D values. Parathyroid hormone and C-telopeptide showed only subtle oscillations of their absolute concentrations or changes from baseline; calcitonin and osteocalcin did not change. Adjustment of final calcemia trend (depletion/accumulation) for relevant risk factors, generally, did not change the results. CONCLUSION: In patients with psychotic disorders and several risks for bone metabolism disturbances antipsychotic treatment was associated with the decrease of calcemia and changes in levels of the associated ions.

Objective A large sample of multi-factor Logistic analysis of clinical biochemical indicators from elderly cataract patients were done to find the characteristics of possible changes in potential factors for cataract-related indicators and explore the pathogenesis of cataract from the perspective of laboratory diagnosis.Methods A retrospective case control study was conducted .Cataract patients from Eye-Ear Nose Throat Hospital of Fudan University were collected during June 2011 to July 2015 and routinely tested for 14 clinical biochemistry indicators including ALB , GLU, TP, GLB, BUN, URCA, Cr, LDH, ALP, Ca, Na, K, Cl, and P.The mean age of the 3 527 cataract patients (1 804 males, 1 723 females) was (64.47 ±11.29) years.Those data were reserved by LIS (Laboratory Information System) system and were retrieved for large data analysis . The control group was filtered from hospitalized patients besides cataract patients during January 2014 to July 2015.The mean age of the 3 333 control subjects ( 1 770 males, 1 563 females ) was ( 64.04 ±9.03 ) years.Biochemical indicators between cataract group and control group were analyzed by independent student′s t-test and Logistic regression .Meanwhile , the objects were divided into 3 groups according to the age (40-59 years,60-79 years,≥80 years) for independent student′s t-test with the control group respectively .Results There are no statistical difference in age ( t=1.663,P=0.096) and gender ( t=2.63,P=0.105 0) between cataract group and control group ( P>0.05).The results of Logistic regression between cataract group and control group were as follow : ALB (OR=1.053,95%CI=1.019-1.088),BUN(OR=1.113,95% CI=1.076-1.152),Cr(OR=1.007, 95%CI=1.003-1.010),GLB(OR=1.049,95% CI=1.018 -1.081),GLU(OR=1.175,95% CI=1.139-1.211),Cl(OR=1.059,1.032 -1.088),Na(OR=1.180,95% CI =1.150 -1.212).Those might be enrolled as risk factors for cataract (P<0.05).The level of ALB, GLU, Na and Cl in cataract group according to different age groups were significantly higher ( t=8.780,t=4.670, t=9.695, t=6.415, P<0.05) than that of control in 40-59 age group;the level of ALB, BUN, Cr, GLU, Na and Cl in cataract group was significantly higher ( t=4.974, t=9.414, t=4.123, t=6.906, t=14.741, t=9.212, P<0.05) than control in 60 -79 age group; the level of BUN, Cr, GLU, Na and Cl in cataract group was significantly higher (t=6.077, t=4.906, t=2.626, t=5.459, t=3.424, P<0.05) than control in 80-age group.Conclusions The level of ALB, BUN, GLB, Cr, GLU, Na and Cl in peripheral blood of cataract patients was significantly increased which suggested that those change might associated with the pathogenesis of cataract .

Edible mushroom powder (Agaricus bisporus) and flavophospholipol improve performance and blood parameters of broilers / Champiñón en polvo (Agaricus bisporus) y flavofosfolipol mejoran el desarrollo y parámetros sanguíneos en pollos de engorde / O uso de champignon em pó (Agaricus bisporus) e flavofosfolipol melhoram o desenvolvimento e parâmetros sanguíneos em frangos de corte

Background: flavophospholipol is an antibiotic growth promoter (AGP). The current ban of AGP in some countries is controversial because their benefits on the environment and economy by saving feed and reducing nitrogen excretion have been overlooked. White button mushrooms have important nutritional properties and the industry discards large quantities of waste that could be fed to animals. Objective: to evaluate the effect of dietary inclusion of five levels of edible mushroom powder (EMP) and flavophospholipol on the performance and blood serum metabolites of broilers. Methods: a total of 300 one-day-old male broiler chicks were randomly distributed into 10 treatments with three replicates of 10 chicks per pen. The experiment consisted of a factorial arrangement (2x5 treatments) with five inclusion levels of EMP supplementation (0, 0.5, 1.0, 1.5, and 2.0 g/kg of diet) and the addition of 0 or 5 mg/kg of flavophospholipol. Results: supplementation with EMP and flavophospholipol, as individual factors, had a negative effect on feed intake, but positively affected broiler weight gains and feed conversion ratio. Antibiotic supplementation increased uric acid concentration and, as an interaction with mushroom powder, reduced serum triglycerides, and very low density lipoprotein cholesterol (VLDL). The EMP also affected serum concentration of total cholesterol. Conclusion: the two substances studied, but not their combination, had a positive effect on growth performance of chickens that could be translated into economic benefits.

Antecedentes: el flavofosfolipol es un antibiótico promotor del crecimiento (AGP). La actual prohibición de los AGP en muchos países es polémica porque sus beneficios económicos y medioambientales a través del ahorro en pienso y la disminución en la producción de heces y nitrógeno son pasados por alto. El champiñón común tiene importantes propiedades nutricionales y la industria desecha grandes cantidades de subproducto que podrían ser aprovechables en la alimentación de animales. Objetivo: evaluar el efecto de cinco niveles de champiñón en polvo (EMP) y flavofosfolipol sobre el desarrollo y metabolitos sanguíneos en suero de pollos de engorde. Métodos: trescientos pollos de engorde machos de un día de vida fueron distribuidos aleatoriamente en 10 grupos en función del tratamiento con tres réplicas de 10 animales. El diseño experimental consistió en un arreglo factorial (2x5 tratamientos), incluyendo cinco concentraciones de champiñón en polvo (0, 0,5, 1,0, 1,5 2,0 g/kg de alimento) y la adición de 0 o 5 mg/kg de flavofosfolipol. Resultados: la suplementación con EMP y flavofosfolipol, individualmente, tiene un efecto negativo en la ingestión diaria de alimento, pero positivo sobre la ganancia de peso vivo y el índice de conversión. La suplementación con antibióticos aumenta la concentración de ácido úrico en sangre e, interaccionando con el champiñón en polvo, disminuye la concentración sérica de triglicéridos y de colesterol de muy baja densidad (VLDL). El EMP también afectó la concentración sérica de colesterol total. Conclusiones: las dos sustancias estudiadas, pero no su combinación, tuvieron un efecto positivo sobre el desarrollo de los pollos de engorde que se puede traducir en un beneficio económico.

Antecedentes: o flavofosfolipol é um antibiótico promotor de crescimento (AGP). A proibição de AGP em muitos países é controversa pois os seus benefícios económicos e ambientais a través da poupança de subministro de alimento e diminuição da produção de fezes e nitrogênio tendem a ser esquecidos. A respeito disso, o cogumelo tem propriedades nutricionais interessantes e a indústria alimentícia rejeita grandes quantidades deste produto que poderiam ser de utilidade para ser aproveitadas na alimentação animal. Objetivo: avaliar o efeito de cinco níveis diferentes do cogumelo em pó (EMP) e da presença ou não de flavofosfolipol sobre o desenvolvimento e a concentração sérica de vários metabolitos em frangos de corte. Métodos: trezentos frangos de um dia foram aleatoriamente divididos em dez grupos de acordo com o tratamento, com três repetições de dez animais. Usou-se um delineamento experimental fatorial (2x5 tratamentos), em que os tratamentos realizados incluíram cinco concentrações de champignon em pó (0, 0,5, 1,0, 1,5 e 2,0 g/kg de ração) e da adição da 0 ou 5 mg/kg flavofosfolipol. Resultados: adicionar flavofosfolipol e cogumelo em pó às dietas exerce, independentemente, uma diminuição sobre a ingestão diária da ração, mas com resultados positivos no ganho de peso e na taxa de conversão alimentar. O antibiótico aumenta a concentração de ácido úrico no sangue; quando está associado com o pó de cogumelo, diminui a concentração sérica de triglicerídeos e colesterol de baixa densidade (VLDL). O consumo do pó de cogumelo afetou a concentração sérica do colesterol total. Conclusões: as duas substâncias estudadas, mas consumidas independentemente, têm um efeito positivo sobre o desenvolvimento com o intuito de ter além, um benefício econômico na produção de frangos de corte.
