RESUMO
ABSTRACT Introduction: Acute kidney injury (AKI) is an abrupt deterioration of kidney function. The incidence of pediatric AKI is increasing worldwide, both in critically and non-critically ill settings. We aimed to characterize the presentation, etiology, evolution, and outcome of AKI in pediatric patients admitted to a tertiary care center. Methods: We performed a retrospective observational single-center study of patients aged 29 days to 17 years and 365 days admitted to our Pediatric Nephrology Unit from January 2012 to December 2021, with the diagnosis of AKI. AKI severity was categorized according to Kidney Disease Improving Global Outcomes (KDIGO) criteria. The outcomes considered were death or sequelae (proteinuria, hypertension, or changes in renal function at 3 to 6 months follow-up assessments). Results: Forty-six patients with a median age of 13.0 (3.5-15.5) years were included. About half of the patients (n = 24, 52.2%) had an identifiable risk factor for the development of AKI. Thirteen patients (28.3%) were anuric, and all of those were categorized as AKI KDIGO stage 3 (p < 0.001). Almost one quarter (n = 10, 21.7%) of patients required renal replacement therapy. Approximately 60% of patients (n = 26) had at least one sequelae, with proteinuria being the most common (n = 15, 38.5%; median (P25-75) urinary protein-to-creatinine ratio 0.30 (0.27-0.44) mg/mg), followed by reduced glomerular filtration rate (GFR) (n = 11, 27.5%; median (P25-75) GFR 75 (62-83) mL/min/1.73 m2). Conclusions: Pediatric AKI is associated with substantial morbidity, with potential for proteinuria development and renal function impairment and a relevant impact on long-term prognosis.
RESUMO Introdução: Insuficiência renal aguda (IRA) é uma deterioração abrupta da função renal. A incidência de IRA pediátrica está aumentando em todo o mundo, em ambientes críticos e não críticos. Nosso objetivo foi caracterizar apresentação, etiologia, evolução e desfechos da IRA em pacientes pediátricos internados em um centro de atendimento terciário. Métodos: Realizamos estudo retrospectivo observacional de centro único de pacientes com idade entre 29 dias a 17 anos e 365 dias internados em nossa Unidade de Nefrologia Pediátrica, de janeiro de 2012 a dezembro de 2021, com diagnóstico de IRA. A gravidade da IRA foi categorizada de acordo com os critérios do Kidney Disease Improving Global Outcomes (KDIGO). Os desfechos considerados foram óbito ou sequelas (proteinúria, hipertensão ou alterações na função renal em avaliações de acompanhamento de 3 a 6 meses). Resultados: Incluímos 46 pacientes com idade mediana de 13,0 (3,5-15,5) anos. Cerca de metade (n = 24; 52,2%) apresentou um fator de risco identificável para o desenvolvimento de IRA. Treze pacientes (28,3%) eram anúricos; todos foram classificados como IRA KDIGO 3 (p < 0,001). Quase um quarto (n = 10; 21,7%) dos pacientes necessitaram de terapia renal substitutiva. Aproximadamente 60% (n = 26) apresentou pelo menos uma sequela, sendo proteinúria a mais comum (n = 15; 38,5%; mediana (P25-75) da relação proteína/creatinina urinária 0,30 (0,27-0,44) mg/mg), seguida de taxa de filtração glomerular (TFG) reduzida (n = 11; 27,5%; mediana (P25-75) da TFG 75 (62-83) mL/min/1,73 m2). Conclusões: A IRA pediátrica está associada à morbidade substancial, com potencial para desenvolvimento de proteinúria e comprometimento da função renal e impacto relevante no prognóstico de longo prazo.
RESUMO
Abstract In the past decades, an epidemic of chronic kidney disease (CKD) has been associated with environmental and occupational factors (heat stress from high workloads in hot temperatures and exposure to chemicals, such as pesticides and metals), which has been termed CKD of non-traditional origin (CKDnt). This descriptive review aims to present recent evidence about heat stress, pesticides, and metals as possible causes of CKDnt and provide an overview of the related Brazilian regulation, enforcement, and health surveillance strategies. Brazilian workers are commonly exposed to extreme heat conditions and other CKDnt risk factors, including increasing exposure to pesticides and metals. Furthermore, there is a lack of adequate regulation (and enforcement), public policies, and strategies to protect the kidney health of workers, considering the main risk factors. CKDnt is likely to be a significant cause of CKD in Brazil, since CKD's etiology is unknown in many patients and several conditions for its development are present in the country. Further epidemiological studies may be conducted to explore causal associations and estimate the impact of heat, pesticides, and metals on CKDnt in Brazil. Moreover, public policies should prioritize reducing workers´ exposure and promoting their health and safety.
Resumo Nas últimas décadas, uma epidemia de doença renal crônica (DRC) tem sido associada a fatores ambientais e ocupacionais (estresse térmico decorrente de cargas de trabalho elevadas em altas temperaturas e exposição a produtos químicos, como agrotóxicos e metais), denominada DRC de origem não tradicional (DRCnt). Esta revisão descritiva tem como objetivo apresentar evidências recentes sobre estresse térmico, agrotóxicos e metais como possíveis causas de DRCnt e fornecer uma visão geral das estratégias brasileiras de regulamentação, fiscalização e vigilância sanitária relacionadas. Os trabalhadores brasileiros são comumente expostos a condições extremas de calor e outros fatores de risco de DRCnt, incluindo o aumento da exposição a agrotóxicos e metais. Além disso, há uma falta de regulamentação e fiscalização, políticas públicas e estratégias adequadas para proteger a saúde renal dos trabalhadores em relação aos principais fatores de risco. É provável que a DRCnt seja uma causa significativa de DRC no Brasil, uma vez que a etiologia da doença é desconhecida em muitos pacientes e diversas condições para seu desenvolvimento estão presentes no país. Estudos epidemiológicos devem ser realizados para explorar associações causais e estimar o impacto do calor, dos agrotóxicos e dos metais na DRCnt no Brasil. Além disso, as políticas públicas devem priorizar a redução da exposição dos trabalhadores e a promoção de sua saúde e segurança.

RESUMO
Cold and heat belong to the eight-principal syndrome differentiation of traditional Chinese medicine， which can reflect the rise and fall of Yin and Yang in the body and the Yin and Yang nature of the disease. At present， traditional Chinese medicine has an inconsistent understanding of cold and heat in acute coronary syndrome. The emphasis on pathogenic factors of cold and heat is biased， and the elements of cold and heat syndrome are not fully reflected in the scale. Therefore， the literature has been reviewed from the perspectives of etiology， pathogenesis， symptom elements， and test signs with drugs. From the perspective of etiology， both cold evil and heat evil can increase the risk of acute coronary syndrome. It was previously believed that acute coronary syndrome occurs frequently in cold climates such as winter and spring. Based on this understanding， hot weather can also induce acute coronary syndrome， and different temperatures have different effects on patients of different ages and with different underlying diseases. In addition， artificial pathogenic factors such as excessive consumption of cold food and refrigeration air conditioners were added. From the perspective of pathogenesis， on the basis of the traditional ''asthenia in origin and asthenia in superficiality'' and ''phlegm stagnation''， it is found that Yin-cold and fire-heat can both cause paralysis of the heart chakra and pain induced by the blockage. The pathogenesis of acute coronary syndrome characterized by heat stagnation and coldness featuring heartburn should be distinguished from gastroesophageal reflux disease. Moreover， the pathogenesis of Yin cold coagulation and pulse stagnation and wind obstruction are different. The acute coronary syndrome is in line with the wind characteristics of frequent changes and can be treated with wind medicine. From the perspective of syndrome elements， the syndrome elements such as cold condensation， heat accumulation， and toxicity are analyzed， and the use of basic syndrome elements and their combination forms facilitates clinical and scientific research. In addition， according to the test sign with the drug， it can be seen that the attributes of cold and heat of traditional Chinese medicine prescriptions for acute coronary syndrome can be explained according to the temperature-sensitive transient receptor potential （TRP） ion channel， thus proving the pathogenesis of cold and heat of acute coronary syndrome.
RESUMO
Objective To explore the differential diagnostic indicators of adult-onset Still's disease(AOSD)from other fever of unknown origin(FUO).Methods The clinical data and laboratory indicators of 177 AOSD patients and 163 FUO patients who were hospitalized in the First Affiliated Hospital of Army Medical University from January 2010 to May 2021 were collected,and the patients were randomly divided into training group and verification group.Statistically significant variables were extracted from univariate analysis for receiver operating characteristic(ROC)curve analysis and the best cut-off value of the variables was obtained.The differential diagnostic indicators were extracted by multivariate logistic regression analysis and nomogram model was constructed.ROC curve,calibration curve,and decision curve analysis were used to evaluate the accuracy and stability of nomogram.Results Univariate analysis revealed that there were significant differences in 4 clinical features(arthralgia,rash,pharyngeal pain,myalgia)and 14 laboratory parameters[white blood cell count(WBC),monocyte percentage,neutrophil percentage,lymphocyte percentage,platelet count,C-reactive protein,interleukin-6(IL-6),ferritin,globulin,immunoglobulin A,and immunoglobulin G(IgG),creatine kinase,creatinine and complement C3].Multivariate analysis suggested that arthralgia,WBC≥9.995×109/L,IL-6≥98.13 ng/L,ferritin≥507.37 ng/ml,globulin≤36.58g/L,IgG≤13.59g/L,complement C3≥1.27 g/L were related with AOSD.The area under curve(AUC)values of training group and verification group were 0.917(95%CI 0.883-0.951)and 0.869(95%CI 0.802-0.936),respectively.The calibration curves showed good consistency.The decision curve analysis showed that training group and verification group had a large positive rate of return in the wide risk range of 5%-85%and 10%-85%,respectively.Conclusions This study has established a relatively accurate AOSD differential diagnosis model.The combination of arthralgia,WBC,IL-6,ferritin,globulin,IgG and complement C3 may help to distinguish AOSD from other causes of FUO.
RESUMO
Objective:To analyze the causes of out-of-hospital cardiac arrest (OHCA) and the differences in outcomes of pre-hospital first-aid measures and cardiopulmonary resuscitation for different etiologies, improved the success rate of rescue.Methods:A retrospective study was conducted on OHCA patients admitted to Beijing Emergency Medical Centre from January to December 2021. The pre-hospital emergency medical records and rescue results within medical institutions were collected. Compared the basic situation between patients with cardiogenic and non-cardiogenic cardiac arrest, the differences of rescue measures and CPR outcomes between the groups were compared by non-parametric test and χ 2 test. Results:A total of 7 517 patients were included in this study. Cardiogenic arrest patients were older, more underlying diseases (84.2%), and cardiac arrest mainly occurred at home. The cause of non-cardiogenic arrest included disease (85.1%), trauma (2.9%), suicide (5.0%), traffic accidents (1.7%), poisoning (1.1%), and so on. In terms of first-aid measures, after the emergency doctor arrived at the scene, the proportion of first-aid measures used for cardiogenic patients was high (22.3%), and the first aid measures include cardiopulmonary resuscitation, tracheal intubation, defibrillation, oxygen inhalation, injection of adrenaline and use of other drugs. All the proportions of first-aid measures for cardiogenic patients were significantly higher than non-cardiogenic patients (all P<0.001). In terms of clinical outcomes, there were no statistical differences in return of spontaneous circulation ( P=0.072) and 24-hour survival ( P=0.093) between cardiogenic and non-cardiogenic patients. Conclusions:Cardiogenic cardiac arrest was the main cause of OHCA. Cardiogenic arrest patients were more underlying diseases, and older in age, the main clinical feature was onset at home. The comprehensive treatment measures for pre-hospital first-aid cardiac arrest should continue to be strengthened to improve the success rate of rescue for OHCA.
RESUMO
Objective To investigate the etiology and outcome of elderly patients with new-onset status epilepticus(NOSE).Methods According to the electronic medical record,the keywords"Epilepsy"and"Status epilepticus"were searched for elderly patients with status epilepticus admitted to Sichuan Provincial People's Hospital between January 2018 and June 2023.Elderly patients with NOSE were strictly screened according to inclusion and exclusion criteria,and etiology were analyzed according to medical history and ancillary examinations,and factors related to prognosis of epilepsy were analyzed by Logistic regression.Results There were 63 elderly NOSE patients,including 38 males and 25 females,with an average age of(72.71±7.45)years old.Cerebrovascular disease(21%)was determined as the major cause of NOSE in elderly patients,followed by central nervous system infection(17%).Logistic regression analysis of prognostic factors showed that co-infection(OR = 11.67,95%CI:1.391-97.850,P =0.024)and renal insufficiency(OR =18.90,95%CI:3.522-101.43,P = 0.001)were associated with poor patient prognosis.Conclusions Cerebrovascular disease is the main known cause of NOSE in elderly patients.Prevention of infection and improvement of renal function may improve prognosis.

RESUMO
BACKGROUND:Currently,there is a lack of large sample studies to analyze the bone metabolism level of patients with femoral head necrosis of different etiologies and stages,which is not conducive to the development of better necrosis-promoting repair strategies. OBJECTIVE:To study the bone metabolism of patients with osteonecrosis of the femoral head with different etiologies and Association Research Circulation Osseous(ARCO)stages. METHODS:A retrospective study was performed on 401 patients diagnosed with osteonecrosis of the femoral head as the trial group,and 81 healthy subjects as the control group.The trial group could be divided into three groups according to different etiologies:steroid-induced osteonecrosis of the femoral head,alcoholic osteonecrosis of the femoral head and traumatic osteonecrosis of the femoral head,and were divided into stages Ⅱ/Ⅲ/Ⅳ according to different ARCO stages.Seven bone metabolism-related indicators of all subjects were collected,including bone metabolism-regulating hormone 25-hydroxyvitamin D and bone conversion markers:N-terminal propeptide of type Ⅰ procollagen,degradation product of type Ⅰ collagen,n-terminal middle molecular fragment of osteocalcin,general biochemical markers of bone metabolism:serum calcium,serum phosphorus,serum alkaline phosphatase.The bone metabolism levels of each group were compared and the independent factors associated with osteonecrosis of the femoral head were determined by binary Logistic regression analysis. RESULTS AND CONCLUSION:Compared with the control group,levels of degradation product of type Ⅰ collagen,N-terminal propeptide of type Ⅰ procollagen,n-terminal middle molecular fragment of osteocalcin,serum phosphorus and alkaline phosphatase in the trial group were significantly increased(all P＜0.05).Based on the presence or absence of the disease,according to binary Logistic regression analysis,degradation product of type Ⅰ collagen,N-terminal propeptide of type Ⅰ procollagen,and n-terminal middle molecular fragment of osteocalcin were independent factors associated with osteonecrosis of the femoral head.The levels of degradation product of type Ⅰ collagen and N-terminal propeptide of type Ⅰ procollagen in three groups of patients with different etiologies were higher than normal reference values.The bone metabolism-regulating hormone 25-hydroxyvitamin D and serum calcium in the alcoholic osteonecrosis of the femoral head group were higher than those in the other two groups(P＜0.05).The level of bone metabolism-regulating hormone 25-hydroxyvitamin D in steroid-induced and traumatic osteonecrosis of the femoral head groups was lower than the normal value.There were no significant differences in seven bone metabolism-related indicators in patients with ARCO stages Ⅱ,Ⅲ and Ⅳ osteonecrosis of the femoral head(all P＞0.05),but degradation product of type Ⅰ collagen and N-terminal propeptide of type Ⅰ procollagen in these three groups were higher than normal reference values.Bone metabolism-regulating hormone 25-hydroxyvitamin D in patients with ARCO stage Ⅱ and ARCO stage Ⅳ was lower than the normal reference value.It is concluded that the bone metabolism level of osteonecrosis of the femoral head patients was abnormal.The degradation product of type Ⅰ collagen and N-terminal propeptide of type Ⅰ procollagen of osteonecrosis of the femoral head patients with different etiologies and ARCO stages were all higher than the normal reference value,and they were in a state of high bone turnover.Degradation product of type Ⅰ collagen,N-terminal propeptide of type Ⅰ procollagen and n-terminal middle molecular fragment of osteocalcin may be risk factors for the pathogenesis of osteonecrosis of the femoral head.
RESUMO
BACKGROUND:Free vascularized fibular grafting is an effective hip preservation treatment for femoral head osteonecrosis,but its influencing factors are still controversial. OBJECTIVE:To explore the clinical efficacy of free vascularized fibular grafting for femoral head osteonecrosis,and the influence of the etiology and severity of femoral head osteonecrosis on its efficacy. METHODS:Clinical data and clinical efficacy scores of preoperative and postoperative hip joints in 63 patients with femoral head osteonecrosis(73 cases of hip)were enrolled.The subjects were divided into three groups by the etiological classification criteria of femoral head osteonecrosis,including glucocorticoid-associated,alcohol-associated,and idiopathic groups,and also were divided into three groups by the Ficat classification system,including Ficat Ⅱ,Ficat Ⅲ and Ficat Ⅳ groups.The effects of etiological classification and lesion degree on the clinical efficacy of free vascularized fibular grafting for femoral head osteonecrosis were analyzed. RESULTS AND CONCLUSION:(1)The visual analog scale scores in all periods after free vascularized fibular grafting for femoral head osteonecrosis were significantly decreased compared with preoperative data(P<0.001),and Harris scores were significantly increased compared with preoperative data(P<0.001).(2)In the glucocorticoid-associated,alcohol-associated,and idiopathic groups,except the glucocorticoid-associated group,postoperative Harris scores were significantly increased 2 and 3 years after surgery in other groups compared with preoperative data(P<0.05).(3)In the three groups of Ficat Ⅱ,Ficat Ⅲ,and Ficat Ⅳ,the postoperative Harris scores of Ficat Ⅱ and Ficat Ⅲ groups were significantly increased compared with preoperative data(P<0.05),while the difference was not significant in the Ficat Ⅳ group between the preoperative and postoperative data(P>0.05).(4)These results indicate that the clinical effect of free vascularized fibular grafting for the femoral head osteonecrosis is significant,which can reduce hip pain and improve hip joint function.It may not be affected by the etiology,but by the severity of the femoral head osteonecrosis.

Objective To analyze the epidemiological characteristics of hand-foot-mouth disease(HFMD)in Gan-zhou.Methods The epidemiological data of HFMD reported by the Infectious Disease Surveillance System,a sub-system of China Disease Prevention and Control Information System,from 2017 to 2020 were analyzed by descriptive methods.Enterovirus(EV)nucleic acid and typing detections via throat swabs,anal swabs or herpes fluid of patients was detected by real-time fluo-rescent polymerase chain reaction.The change in HFMD epidemic characteristics was compared between 2020 and 2017-2019.Results The incidence of HFMD in Ganzhou in 2020 was significantly lower than that from 2017 to 2019(x2=50.587,P＜0.05).In 2020,the incidence of HFMD in counties and districts of Ganzhou(except Huichang County)signifi-cantly decreased compared with that in 2017-2019(P＜0.05).From 2017 to 2019,the incidence of HFMD was obviously seasonal,with a high incidence in summer and autumn,and two significant incidence peaks were formed in June and September in 2017 and 2018,respectively.In 2019,there was a summer peak in June.The epidemic trend in 2020 was different,with a very low epidemic trend in summer and autumn,and a peak in winter.The incidence of HFMD in men,women and all ages in 2020 significantly decreased compared with that in 2017-2019(P＜0.05),and the age of onset was mainly distributed in 1-5 years,especially in children aged 1 to 3 years.There was a significant difference in the incidence of HFMD among different ages(P＜0.05).The positive rate of EV in Ganzhou in 2020 was lower than that from 2017 to 2019(x2=47.273,P＜0.05).The positive rate of EV in January,March to September in 2020 was significantly lower,and the positive rate of EV in November,December 2020 was significantly higher than that in the same period in 2017 to 2019(P＜0.05).Strain CA16 showed an increasing trend year by year from 2017 to 2019,and became the dominant strain in 2019.The proportion of patients infected with CA6 strain was on the fise from 2018 to 2020,and CA6 became the dominant strain in 2020.Conclusion The HFMD in Ganzhou has obvious population characteristics and seasonality,and the pathogen spectrum is constantly changing.
RESUMO
Acute gallstone pancreatitis (AGP) is a kind of acute pancreatitis caused by gallstones. The etiology of AGP is complex, and the anatomic basis and initiating factors have a synergistic effect on its pathogenesis, which needs to be studied jointly. The way of the confluence of pancreaticobiliary ducts, dilated main pancreatic duct, the relatively narrow opening of duodenal papilla and small stones or microlithiasis may be involved in the pathogenesis of AGP, in which small stones are the most important. Etiological diagnosis and clinical treatment of AGP should be carried out simultaneously. The timely selection of treatment methods for different causes can alleviate the patient's condition to the greatest extent and reduce the cost of treatment. At present, it is difficult to unify the prediction indexes of AGP. Meanwhile, the pathogenesis and related prophylaxis and treatment also need to be studied. In this paper, the anatomic basis, initiation factors, pathogenesis and self-defense of AGP were analyzed to provide a new perspective for its treatment.

RESUMO
Syndrome differentiation and treatment is a traditional Chinese medicine （TCM）-featured concept and method in diagnosis and treatment， which needs to be combined with the intelligent diagnosis of TCM in the future. At present， the intelligent diagnosis of TCM has gradually changed from the simple data-driven primary intelligence to the knowledge-driven advanced intelligence that integrates professional knowledge. Although syndrome element differentiation breaks down the elements of TCM diagnostic knowledge to form syndrome elements， which makes the original vague knowledge information more specific， the relationship between syndrome elements is not well classified and sorted out， resulting in the lack of hierarchical relationship and connection between syndrome elements， and thereby causing obstacles to the application of intelligent technology. Based on the understanding of etiology and pathogenesis from TCM， this paper concretized the syndrome element set of etiology， disease location and disease nature in TCM syndrome differentiation and treatment， and formed a knowledge framework system of syndrome elements with clear logical relationship， clear hierarchy and good explanation， thereby providing certain reference for realizing knowledge-driven advanced intelligence syndrome differentiation in the future.
RESUMO
ObjectiveTo analyze the epidemiological characteristics and etiology of clustered outbreaks of hand， foot， and mouth disease （HFMD） in Pudong New Area， Shanghai from 2017 to 2022， and to provide a scientific basis for the prevention and control of HFMD in the area. MethodsThe data related to HFMD clustered outbreaks from 2017 to 2022 were obtained from the Pudong New Area HFMD outbreak database. Descriptive analysis was conducted to explore the outbreak scope， seasonal characteristics， distribution of occurrence settings， and etiological composition. ResultsFrom 2017 to 2022， Pudong New Area reported a total of 2 547 HFMD clusters， involving 8 884 cases， with an average of 3.49 cases per event. The majority of events （78.52%） had between 2 and 4 cases. The peak reporting periods for clustered HFMD from 2017 to 2019 and in 2021 were during the summer （May‒July） and autumn （September‒November）. The seasonal pattern was less distinct in 2020 and 2022， likely due to the impact of the COVID-19 pandemic. The majority of clustered outbreaks occurred in childcare facilities （44.64%）， followed by households/neighborhood committees （44.21%）， with schools accounting for a smaller proportion （12.39%）. The etiology revealed the coexistence of multiple enterovirus genotypes， with a positive detection rate of 60.46%， and CoxA6 being the dominant strain. ConclusionHFMD clustered outbreaks in Pudong New Area show fluctuating trends， with significant yearly differences in the number of incidents. The predominant seasons for outbreaks are summer and autumn， with CoxA6 identified as the dominant strain. The implementation of prevention and control measures for COVID-19 significantly reduced the occurrence of HFMD outbreaks.
