ABSTRACT
Este artigo se baseia em um estudo feito com o objetivo de analisar indicadores sobre a testagem da sífilis na gestação no Programa de Qualificação das Ações de Vigilância em Saúde (PQAVS) e no Programa Previne Brasil no estado da Paraíba, e também de levantar aspectos do tratamento terapêutico para sífilis gestacional. Trata-se de uma pesquisa descritiva-exploratória, na qual foram sistematizados dados do indicador 11, testes por gestantes, do PQAVS e do indicador de desempenho da Atenção Primária à Saúde (APS), com base na proporção de gestantes que realizaram exames de sífilis e HIV durante o pré-natal em 2020; também foi feita a sistematização do webquestionário direcionado a profissionais da APS (médicos/enfermeiros) e autoaplicado sobre a atuação e tratamento terapêutico para sífilis gestacional. Dos 223 municípios da Paraíba, apenas 12% atingiram a meta do PQAVS e 39% a do Previne Brasil em 2020. Em relação ao webquestionário, houve a participação de 142 profissionais, dos quais 85% realizam o tratamento terapêutico preconizado pelo Ministério da Saúde para a APS. Desse modo, deve ser ressaltada a importância da ampliação da oferta de testes para sífilis, dos insumos para o tratamento adequado e da qualificação dos profissionais e da informação em saúde.
This article is based on a study to analyze indicators on syphilis testing during pregnancy in the PQAVS - Programa de Qualificação das Ações de Vigilância em Saúde (Health Surveillance Actions Qualification Programme) and in the Programa Previne Brasil (Previne Brasil Programme) in the state of Paraíba, Brazil, and also to survey aspects of the therapeutic management for gestational syphilis. It is a descriptive-exploratory research, in which data from indicator 11, tests for pregnant women, from the PQAVS and from the Primary Health Care (PHC) performance indicator, based on the proportion of pregnant women with syphilis and HIV tests during prenatal care in 2020 were systematised; in addition to this systematization, a self-administered webquestionnaire on the performance and therapeutic management for gestational syphilis by professionals (doctors/nurses) from the PHC was also systematised. Taking into account the 223 municipalities in Paraíba, only 12% reached the PQAVS goal and 39% reached the Previne Brasil goal in 2020. Regarding the webquestionnaire, 85% of the 142 professionals who answered it, carry out the therapeutic management recommended by the Ministry of Health for the PHC. Thus, it is fundamental to emphasise the importance of expanding the supply of tests for syphilis, supplies for adequate treatment, and the qualification of health professionals and information.

Abstract With the upsurge of community uptake in popula tion-based early screening for autism, the main obstacle to increasing access to early treatment and intervention services is the extremely limited access to high quality diagnosis, specifically the shortage of expert clinicians. Diagnostic evaluation models deployed by academic cen ters of excellence, which typically require the investment of 6-10 hours by specialized multidisciplinary teams, is not a viable solution to the vast needs of communities, resulting in parents' "diagnostic odysseys" and delays, often of several years, for treatment, interventions and supports. Biomarker-based objective procedures for early diagnosis and assessment of autism are now available, clinically validated, and cleared for broad implementa tion by the US Food and Drug Administration (FDA). They are intended to increase access while maintaining high quality. Such solutions, however, will require change in entrenched models of diagnostic care, and aggressive prioritization of the needs of the community at large. If these innovations are successful, the number of children diagnosed in the first three years of life will double or triple. This will, in turn, require much greater inves tments in resources for treatment, including massive workforce training of providers capable of delivering community-viable caregiver-mediated interventions, and of early educators capable of serving autistic children in therapeutic inclusive preschool settings.
Resumen Con el aumento de la aceptación comunitaria de la detección temprana del autismo basada en la pobla ción, el principal obstáculo para aumentar el acceso al tratamiento temprano y a los servicios de intervención es el acceso extremadamente limitado a un diagnóstico de alta calidad, específicamente la escasez de médicos expertos. Los modelos de evaluación diagnóstica imple mentados por centros académicos de excelencia, que normalmente requieren la inversión de 6 a 10 horas por parte de equipos multidisciplinarios especializados, no son una solución viable para las vastas necesidades de las comunidades, lo que resulta en "odiseas diagnósti cas" y retrasos, a menudo de gran importancia, para los padres varios años, para tratamiento, intervenciones y apoyos. Los procedimientos objetivos basados en bio marcadores para el diagnóstico temprano y la evaluación del autismo ya están disponibles, clínicamente validados y aprobados para su amplia implementación por la Ad ministración de Alimentos y Medicamentos de EE. UU. (FDA). Su objetivo es aumentar el acceso manteniendo una alta calidad. Sin embargo, tales soluciones requeri rán cambios en los modelos arraigados de atención de diagnóstico y una priorización agresiva de las necesida des de la comunidad en general. Si estas innovaciones tienen éxito, el número de niños diagnosticados en los primeros tres años de vida se duplicará o triplicará. 51 Esto, a su vez, requerirá inversiones mucho mayores en recursos para el tratamiento, incluida la capacitación masiva de la fuerza laboral de proveedores capaces de brindar intervenciones comunitarias viables mediadas por cuidadores, y de educadores tempranos capaces de atender a niños autistas en entornos preescolares terapéuticos inclusivos.
ABSTRACT
BACKGROUND@#Low-dose spiral computed tomography (LDCT) has been recommended for lung cancer screening in high-risk populations. However, evidence from Chinese populations was limited due to the different criteria for high-risk populations and the short-term follow-up period. This study aimed to evaluate the effectiveness in Chinese adults based on the Lung Cancer Screening Program in Minhang District of Shanghai initiated in 2013.@*METHODS@#A total of 26,124 subjects aged 40 years or above were enrolled in the Lung Cancer Screening Program during the period of 2013 and 2017. Results of LDCT examination, and screen-detected cancer cases in all participants were obtained from the Reporting System of the Lung Cancer Screening Program. The newly-diagnosed cases and their vital status up to December 31, 2020 were identified through a record linkage with the Shanghai Cancer Registry and the Shanghai Vital Statistics. Standardized incidence ratio (SIR) and 95%CI were calculated using the local population at ages of 40 or above as the reference. Proportions of early-stage cancer (stage 0-I), pathological types, and 5-year observed survival rates of lung cancer cases were estimated and compared between the cases derived from the screened and non-screened populations. Cox regression models were applied to evaluate the hazard ratio (HR) and 95%CI of LDCT screening with all-cause death of the lung cancer cases.@*RESULTS@#The crude and age-standardized incidence of lung cancer in screened population were 373.3 (95%CI: 343.1-406.1) and 70.3 per 100,000 person-years, respectively, with an SIR of 1.8 (95%CI: 1.6-1.9), which was observed to decrease with following-up time. The early-stage cancer accounted for 49.4% of all lung cancer cases derived from the screened population, significantly higher than 38.4% in cases from the non-screened population during the same period (P<0.05). The proportion of lung adenocarcinoma (40.7% vs 35.9%) and 5-year survival rate (53.7% vs 41.5%) were also significantly higher in the cases from the screened population (all P<0.05). LDCT screening was associated with 30% (HR=0.7, 95%CI: 0.6-0.8) reduced all-cause deaths of the cases.@*CONCLUSIONS@#The participants of the screening program are at high-risk of lung cancer. LDCT favors the early-detection of lung cancer and improves 5-year survival of the screened cases, indicating a great potential of LDCT in reducing the disease burden of lung cancer in Chinese populations.

Early/late onset sepsis(EOS/LOS)and necrotizing enterocolitis(NEC)are common diseases during the neonatal period,with poor prognosis in severe cases.The early clinical manifestations are not specific,the diag-nosis is difficult,currently-used non-specific laboratory tests(C-reactive protein,procalcitonin,etc.)have disad-vantages,which may lead to missed diagnosis or misdiagnosis.Serum amyloid A(SAA)is a novel acute phase re-actant that increases significantly in the early stage of EOS/LOS and NEC,and lasts for a long time,it is related to the severity of the disease and can reflect the therapeutic effect,thus it can be used as a biomarker for diagnosis and treatment of these two diseases.This paper reviews SA A and its value in the early diagnosis of EOS/LOS and NEC,providing new references for the diagnosis and treatment of such diseases.
ABSTRACT
Sepsis is caused by infection, which can ultimately lead to multiple organ dysfunction and even life-threatening. Early recognition and early treatment can significantly improve the prognosis of sepsis patients. However, the effect of using a single biomarker for early diagnosis of sepsis is still not ideal. In recent years, researchers have turned their attention to artificial intelligence technology for early diagnosis of sepsis. This paper briefly introduces the advantages and disadvantages of sepsis related inflammatory indicators, biomarkers, and scoring systems of disease severity for early identification of sepsis, and focuses on the research progress and limitations of artificial intelligence technology for early diagnosis of sepsis, aiming to seek new methods and ideas for early diagnosis of sepsis.
ABSTRACT
Objective:To explore the clinical and electrophysiological characteristics of peripheral neuropathy in prediabetic patients.Methods:Subjects aged 20-65 years with high-risk factors of impaired glycemia enrolled in Beijing Tiantan Hospital, Capital Medical University from 2019 to 2022 were recruited to conduct oral glucose tolerance test, after excluding other causes of neuropathy or radiculopathy. Patients with impaired fasting glucose or impaired glucose tolerance were defined by American Diabetes Association criteria. These patients were divided into clinical polyneuropathy (PN) and clinical non-PN groups, according to the 2010 Toronto consensus criteria and the presence of PN symptoms and signs or not. Nerve conduction studies (NCS), F wave, sympathetic skin response (SSR), R-R interval variation (RRIV) and current perception thresholds (CPT) were performed and the abnormal rate was compared between different electrodiagnostic methods and between clinical subgroups.Results:Among the 73 prediabetic patients ultimately enrolled, only 20 (27.4%) can be diagnosed as clinical PN according to the Toronto consensus criteria. The abnormal rate of CPT (68.5%, 50/73) was significantly higher than those of F wave (2.7%, 2/73), lower limb NCS (0, 0/73), upper limb NCS changes of carpal tunnel syndrome (26.0%, 19/73), SSR (6.8%, 5/73) and RRIV (5.5%, 4/73; McNemar test, all P<0.001). With sinusoid-waveform current stimuli at frequencies of 2 000 Hz, 250 Hz and 5 Hz, the CPT device was used to measure cutaneous sensory thresholds of large myelinated, small myelinated and small unmyelinated sensory fibers respectively. CPT revealed a 21.9% (16/73) abnormal rate of unmyelinated C fiber in the hands of prediabetic patients, significantly higher than that of large myelinated Aβ fibers [8.2% (6/73), χ2=5.352, P=0.021]. Both abnormal rates of small myelinated Aδ [42.5% (31/73)] and unmyelinated C fibers [39.7% (29/73)] in the feet of prediabetic patients were significantly higher than that of large myelinated Aβ fibers [11.0% (8/73), χ2=18.508, 15.965, both P<0.001]. Compared with the clinical non-PN group, the abnormal rates of CPT [90.0% (18/20) vs 60.4% (32/53), χ2=5.904, P=0.015] and SSR [20.0% (4/20) vs 1.9% (1/53), P=0.016) were significantly higher in the clinical PN group. Conclusions:Peripheral neuropathies in prediabetic patients are usually asymptomatic or subclinical, and predispose to affect unmyelinated and small myelinated sensory fibers. Selective electrodiagnostic measurements of small fibers help to detect prediabetic neuropathies in the earliest stages of the disease.
ABSTRACT
Objective:To explore the combination of high risk screening and family screening for potential patients with Fabry disease in adult hemodialysis population, and to improve the diagnostic efficiency of the disease.Methods:It was a cross-sectional investigation study. High-risk screening for Fabry disease was performed on adult hemodialysis patients with end-stage kidney disease who were admitted to Yongkang First People's Hospital of Zhejiang Province between November 2022 and February 2023. Dry blood paper α-galactosidase A (α-Gal A) detection assay was performed in males, or glycosphingolipids (Lyso-GL-3) detection assay was performed in females. GLA genetic assay was performed for further diagnosis after abnormal screening results. Family screening was carried out on the family members of the confirmed Fabry disease patients, and α-Gal A activity and Lyso-GL-3 of peripheral blood were measured. Additionally, urine routine, blood biochemistry, eye examination, hearing test, cranial magnetic resonance imaging, and electrocardiogram were performed to assess organ damage. Results:Among 244 hemodialysis patients, 139 (56.97%) were males and 105 (43.03%) were females. The age ranged from 25 to 81 years (with median age of 61 years). One female patient with Fabry disease was identified GLA IVS4+919G>A mutation, resulting in a total prevalence of 0.41%. Pedigree screening was conducted on 41 family members of the patient, leading to the confirmation of 12 patients (including the proband), including 3 males and 9 females. Among them, 9 patients were abnormal in enzyme examination, 10 patients were abnormal in substrate, and 11 patients were abnormal in gene sequencing. None of the 12 patients exhibited limb pain, hypohidrosis, angiokeratoma, corneal opacity, and hearing impairment. Eight patients had heart abnormalities. Nine patients had abnormal urine routine (albuminuria or hematuria) and one patient had abnormal renal function. Four patients had abnormal cranial magnetic resonance imaging findings. Conclusions:One GLA IVS4+919G>A mutation family is successfully identified through the combination of high-risk screening and family screening in adult hemodialysis patients, with a total of 12 cases of Fabry disease. The combination of high-risk screening and family screening proves to be effective in detecting potential patients with Fabry disease, and improve the screening efficiency of Fabry disease.
ABSTRACT
Exosomes are nanoscale extracellular vesicle structures that communicate and exchange information between cells. They carry a variety of biologically active molecules whose compositions and contents vary according to the origin and recipient cells. Therefore, exosomes can be used as biomarkers. Neurodegenerative diseases are diseases with hidden onset, so early screening and accurate diagnosis is undoubtedly a reliable guarantee to reduce their mortality and increase the cure rate. Exosomes, as a research hotspot in recent years, have great potential for the diagnosis and treatment of diseases given their transport capacity and contents, and have significant advantages in abundance, stability, diversity and accessibility. The purpose of this paper is to discuss exosomes as potential candidates for early diagnosis of neurodegenerative diseases, and thus to elaborate new fields of their application, with a view to providing a richer perspective for clinical prediction and treatment.
ABSTRACT
Hepatocellular carcinoma (HCC) is malignant tumor with the fourth incidence rate and the second mortality rate in China, and patients with advanced stage have lost the chance of surgical treatment, short survival period and extremely poor prognosis. Histopathological biopsy is the gold standard for clinical diagnosis of malignant tumors, but histopathological biopsy is not only invasive, but also obtains fewer tissue samples, which does not reflect the heterogeneity of tumors, and makes it difficult to dynamically monitor the progression of tumors or the efficacy of treatment. Therefore, it is clinically important to find new non-invasive strategies for early detection of HCC and to monitor the efficacy of HCC. Circulating tumor DNA is a non-invasive liquid biopsy method with simple sampling and can dynamically monitor the genomic changes of tumors, which has great application value in early diagnosis, therapeutic efficacy monitoring, and prognostic evaluation of HCC.
ABSTRACT
Karyopherin α2 (KPNA2) , a key protein molecule that regulates the exchange of substances between the nucleus and the cytoplasm, plays an important role in the nucleocytoplasmic transport pathway. In recent years, an increasing number of studies have shown that KPNA2 is involved in a variety of cellular life activities and plays a significant part in viral infection, cell proliferation, immune response and tumor metastasis. Further study of the mechanism of KPNA2 in promoting the hepatocarcinogenesis and exploring its role in the development of liver cancer may provide new ideas for the diagnosis, treatment, and prognosis of liver cancer.
ABSTRACT
Gallbladder carcinoma(GBC)is one of the most common malignant tumors in the biliary system,which is difficult to diagnose in the early stage due to its high degree of malignancy,invasiveness and lack of specific clin-ical manifestations.In this paper,we summarize ultrasound,CT and other imaging manifestations in the early stage of GBC,and describe the role of protein markers and microRNA marker as biomarkers in the diagnosis of early GBC.The enhanced understanding of the relevant features might help to improve the accuracy of the diagnosis of early gallbladder carcinoma.
ABSTRACT
Objective:To observe the expression level of bone morphogenetic protein 9 (bone morphogenetic protein 9,BMP9) in patients with sepsis-associated acute respiratory distress syndrome (acute respiratory distress syndrome,ARDS), and to explore the role of BMP9 in early recognition and prognosis prediction of sepsis-associated ARDS.Methods:From May 2022 to May 2023, total of 56 patients with sepsis-associated ARDS in Shanxi Bethune Hospital were selected as the ARDS group, 49 patients with cardiogenic pulmonary edema as the case control group, and 46 adults who underwent physical examination in the physical examination center of our hospital as the healthy control group.The patients in the ARDS group were followed up for 28 days and divided into survival group ( n = 26) and death group ( n = 30). The expression level of serum BMP9 and its correlation with clinical indicators in each group were analyzed and compared. The risk factors of sepsis-associated ARDS were analyzed by Logistic regression, and the diagnostic efficacy and prognostic value of related indicators were analyzed. Results:The serum level of BMP9 in sepsis-associated ARDS group [1401.14 (856.59,1982.86) ]pg/mL was significantly higher than that in case control group (438.26±128.52) pg/mL and healthy control group (398.96±96.55)pg/mL, the differences were statistically significant ( P<0.01). In addition, BMP9 expression significantly correlated with procalcitonin, lymphocyte count and SOFA score ( P < 0.05, P < 0.01, respectively). Multivariate Logistic regression analysis showed that BMP9 was a high risk factor for the development of sepsis-associated ARDS ( P<0.01). The area under the ROC curve (area under the ROC curve,AUC) of BMP9 to predict the occurrence of sepsis-associated ARDS was 0.930. The specificity was 100.0% and the sensitivity was 80.4%, which was significantly higher than the specificity (89.8%) and sensitivity (67.9%) of the oxygenation index. Follow-up and comparison of BMP9 levels in patients with different prognosis of sepsis-associated ARDS showed that the expression level of BMP9 in the death group was higher than that in the survival group, and the difference was statistically significant ( P < 0.05). The ROC curve of BMP9 in predicting the prognosis of patients with sepsis-associated ARDS. The area under the ROC curve was 0.699, the sensitivity was 43.3%, and the specificity was 100.0%. Conclusions:The expression of BMP9 in sepsis-associated ARDS patients significantly increased, and its high expression was significantly correlated with inflammatory markers such as procalcitonin, lymphocyte count and SOFA score. BMP9 is an independent risk factor in patients with sepsis-associated ARDS, and it is promising as a new biomarker for early identification of sepsis-associated ARDS. However, it do not show a good predictive effect on the prognosis of the disease.
ABSTRACT
Diabetic kidney disease(DKD)is one of the most serious microvascular complications of diabetes and a common cause of end-stage renal disease.Early kidney injury lacks typical clinical symptoms and its onset is insidiously.The common clinical indicators of kidney injury are urine microalbumin,glomerular filtration rate,etc.Due to their lack of sensitivity and specificity,it is easy to cause missed diagnosis,misdiagnosis,and delay the disease.Therefore,it is of great significance to find more convenient,stable,and less invasive detection indicators for the early diagnosis of DKD.This paper reviews the research progress of biological indicators related to glomerular and tubular injury,oxidative stress,inflammatory response,microRNA and proteomics,which provides a certain reference value for the early diagnosis of clinical DKD.
ABSTRACT
Objective To explore the clinical value of methylation at promoter sites of urine protein kinase Y-linked(PRKY)gene in the early diagnosis of prostate cancer(PCa).Methods Urine samples were collected from 50 suspected PCa patients.After extracting DNA,the methylation levels of the PRKY gene promoter sites cg05163709,cg08045599,and cg05618150 were detected using quantitative methylation-specific PCR(qMSP).Simultaneously,the patients were divided into the benign prostatic hyperplasia(BPH)group and the PCa group.The differences in clinical indicators between the two groups were analyzed,as well as the methylation status of the PRKY gene promoter sites in the urine of the two groups of patients.The receiver operating charac-teristic(ROC)curve of PRKY promoter sites methylation was established,and the area under the curve(AUC)was calculated to analyze the diagnostic value of PRKY promoter sites methylation in PCa,and to perform com-bined diagnosis with clinical indicators.Results The methylation rates of cg05163709 and cg05618150 in urine specimens of PCa patients were significantly higher than those of BPH patients.The AUC for cg05163709 methyla-tion in diagnosing PCa was 0.762,with a sensitivity of 86.70%.It showed better performance in early screening for PCa compared to total prostate specific antigen(tPSA),percentage free prostate specific antigen(f/tPSA)and prostate specific antigen density(PSAD)index.We found that the AUC for cg05618150 methylation in conjunc-tion with PSAD in diagnosing PCa was 0.787,with a sensitivity of 86.70%.The AUC of cg05163709 methylation and PSAD in the joint diagnosis of PCa was 0.855,and the specificity could reach 95.00%.Conclusion The methylation of urine PRKY gene promoter sites cg05163709 and cg05618150 shows high sensitivity and specificity in diagnosing PCa,making them promising biomarkers for early detection of PCa.
ABSTRACT
Fibromyalgia syndrome (FMS) is a refractory, chronic non-articular rheumatic disease characterized by widespread pain throughout the body, for which there are no satisfactory therapeutic drugs or options. There are rich Chinese medical therapies, and some non-drug therapies, such as acupuncture, Tai Chi, and Ba-Duan-Jin, have shown satisfactory efficacy and safety and definite advantages of simultaneously adjusting mind and body. FMS is taken as a disease responding specifically to traditional Chinese medicine (TCM) by the National Administration of Traditional Chinese Medicine in 2018. In order to clarify the research progress in FMS and the clinical advantages of TCM/integrated Chinese and Western medicine, the China Academy of Chinese Medicine organized a seminar for nearly 20 experts in Chinese and Western medicine, including rheumatology, psychology, acupuncture and moxibustion, and encephalopathy, with the topic of difficulties in clinical diagnosis and treatment of FMS and advantages of TCM and Western medicine. The recommendations were reached on the difficulties in early diagnosis and solutions of FMS, mitigation of common non-specific symptoms, preferential analgesic therapy, TCM pathogenesis and treatment advantages, and direction of treatment with integrated Chinese and Western medicine. FMS is currently facing the triple dilemma of low early correct diagnosis, poor patient participation, and unsatisfactory benefit from pure Western medicine treatment. To solve the above problems, this paper suggests that rheumatologists should serve as the main diagnostic force of this disease, and they should improve patient participation in treatment decision-making, implement exercise therapy, and fully utilize the holistic and multidimensional features of TCM, which is effective in alleviating pain, improving mood, and decreasing adverse events. In addition, it is suggested that FMS treatment should rely on both TCM and Western medicine and adopt multidisciplinary joint treatment, which is expected to improve the standard of diagnosis and treatment of FMS in China.
ABSTRACT
The incidence rate of abdominal trauma is increasing year by year in pediatric trauma, and traumatic pancreatic injury should be taken seriously by clinicians. The pancreas is located behind the peritoneum, and it is difficult to make an early diagnosis of pancreatic injury, especially in children with grade Ⅰ/Ⅱ injury. Through a literature review, this article analyzes the application value of endocrine indices and abdominal ultrasound in the early diagnosis of pediatric pancreatic injury, so as to improve the rate of early diagnosis and avoid the onset of related complications. Changes of the endocrine indices such as serum insulin and C Peptide have certain advantages in diagnosing and evaluating the degree of pediatric pancreatic injury and can thus be used as early warning indices for pediatric pancreatic injury. Ultrasound elastography provides a new method for the diagnosis and differentiation of pancreatic injury; contrast-enhanced ultrasound, which has no radioactive damage, has relatively high specificity and sensitivity in identifying pediatric pancreatic injury, and therefore, it is expected to become an alternative to CT examination.
ABSTRACT
BACKGROUND:Cervical spondylotic myelopathy is a progressive disease leading to dysfunction in the middle-aged and elderly,and early diagnosis is difficult.In recent years,some clinical scholars have found that dynamic magnetic resonance imaging technology can detect spinal cord compression in a dynamic position earlier,but its specific biomechanical mechanism needs to be clarified. OBJECTIVE:To investigate the biomechanical compression characteristics of early cervical spondylotic myelopathy in hyperextension and flexion position,and to verify the effectiveness of dynamic magnetic resonance imaging in the diagnosis of early cervical spondylotic myelopathy. METHODS:A retrospective analysis was made on the patients who underwent cervical dynamic magnetic resonance imaging in the Department of Orthopedics of First Affiliated Hospital of Guangxi University of Chinese Medicine from January to June 2022.16 subjects were selected and divided into two groups.The pathological group included 8 patients with early cervical spondylotic myelopathy with hypertrophy of ligamentum flavum as the main sign,with 5 male patients and 3 female patients.The normal group included 8 normal degenerative people,with 4 male patients and 4 female patients.All patients were photographed with cervical CT plain scan,magnetic resonance imaging plain scan,and dynamic magnetic resonance imaging plain scan.This study was divided into the following three parts:(1)collect the dynamic magnetic resonance imaging image DCOM data of two groups of subjects,and collect the cervical vertebra CT and neutral magnetic resonance imaging image DCOM data to understand the bone and soft tissue of the two groups of subjects in the neutral position.(2)Based on the DCOM data of magnetic resonance imaging and CT plain scan,the three-dimensional finite element models of lower cervical vertebra(C3-7)of normal degenerative population and early cervical spondylotic myelopathy patients were established by reverse engineering software.The equivalent stress and equivalent elastic strain of the spinal cord and posterior dura were analyzed,and the distribution of stress and strain was observed.(3)After obtaining the stress and strain data,the data between groups were compared to analyze the mechanical characteristics of spinal cord compression caused by early cervical spondylotic myelopathy in a dynamic position and to verify the effectiveness of dynamic magnetic resonance imaging in the diagnosis of early cervical spondylotic myelopathy. RESULTS AND CONCLUSION:(1)When simulating the posterior extension,flexion and neutral position of the lower cervical vertebrae(C3-7)in the two groups,the values of stress and strain in the posterior part of the spinal cord were in the following order:extension>flexion>neutral(P<0.05).The strain values from large to small were as follows:extension>flexion>neutral(P<0.05).(2)Compared with the normal degenerative population model,the equivalent stress and strain of the spinal cord in the pathological group were higher than those in the normal group under two degrees of freedom of flexion and extension(P<0.05).The distribution area of stress and strain in the posterior part of the spinal cord was irregular.(3)In the neutral position,there was no significant difference in the strain value of the spinal cord between the two groups(P>0.05),and the strain distribution was uniform and regular.(4)It is indicated that in the cervical extension position,the dural sac and the posterior part of the spinal cord were compressed and deformed in the early cervical spondylotic myelopathy patients with the hypertrophy of ligamentum flavum as the main sign,and the degree of compression deformation of the spinal cord was significantly higher than that in the anterior flexion position and neutral position.In the neutral position,there were no obvious signs of spinal cord deformation in patients with early cervical spondylotic myelopathy.This study verified the role of dynamic magnetic resonance imaging in the diagnosis of early cervical spondylotic myelopathy from the point of view of biomechanics.
ABSTRACT
Abstract Extracellular vesicles (EVs) are small vesicles released by cells that facilitate cell signaling. They are categorized based on their biogenesis and size. In the context of the central nervous system (CNS), EVs have been extensively studied for their role in both normal physiological functions and diseases like Alzheimer's disease (AD). AD is a neurodegenerative disorder characterized by cognitive decline and neuronal death. EVs have emerged as potential biomarkers for AD due to their involvement in disease progression. Specifically, EVs derived from neurons, astrocytes, and neuron precursor cells exhibit changes in quantity and composition in AD. Neuron-derived EVs have been found to contain key proteins associated with AD pathology, such as amyloid beta (Aß) and tau. Increased levels of Aß in neuron-derived EVs isolated from the plasma have been observed in individuals with AD and mild cognitive impairment, suggesting their potential as early biomarkers. However, the analysis of tau in neuron-derived EVs is still inconclusive. In addition to Aß and tau, neuron-derived EVs also carry other proteins linked to AD, including synaptic proteins. These findings indicate that EVs could serve as biomarkers for AD, particularly for early diagnosis and disease monitoring. However, further research is required to validate their use and explore potential therapeutic applications. To summarize, EVs are small vesicles involved in cell signaling within the CNS. They hold promise as biomarkers for AD, potentially enabling early diagnosis and monitoring of disease progression. Ongoing research aims to refine their use as biomarkers and uncover additional therapeutic applications.
Resumo As vesículas extracelulares (VEs) são pequenas estruturas liberadas pelas células que agem na sinalização celular. No sistema nervoso central (SNC), as VEs são estudadas em relação à doença de Alzheimer (DA), um distúrbio neurodegenerativo que cursa com declínio cognitivo e morte neuronal. As VEs podem ser biomarcadores potenciais para a DA devido ao seu papel na progressão da doença. As VEs derivadas de neurônios, astrócitos e células precursoras apresentam alterações na DA, contendo proteínas associadas à patologia da DA, como beta-amiloide (Aß) e tau. Níveis elevados de Aß foram observados nas VEs de neurônios de indivíduos com DA, sugerindo seu potencial como biomarcadores precoces. A análise de tau nas VEs de neurônios ainda é inconclusiva. Além disso, as VEs neurais carregam outras proteínas relacionadas à DA, incluindo proteínas sinápticas. As VEs podem ser promissoras como biomarcadores para o diagnóstico precoce e monitoramento da DA, porém mais pesquisas são necessárias para validar seu uso e explorar aplicações terapêuticas. Em resumo, as VEs são vesículas envolvidas na sinalização celular no SNC, com potencial como biomarcadores para a DA.
ABSTRACT
SUMMARY OBJECTIVE: The objective of this study was to analyze the factors that influence the positivity of treponemal and non-treponemal tests in cases of congenital syphilis. METHODS: This cross-sectional and correlational study was carried out from the analysis of the database of Disease and Notification Information System (SINAN, in Portuguese) using the data obtained through the Epidemiological Surveillance Group 29, with 639 notifications of congenital syphilis between 2007 and 2018. The data were analyzed by a descriptive and inferential analysis from logistic regression with a significance level of 5% (p≤0.05). RESULTS: The positivity of the treponemal test was higher by 4.5 times in infants living in rural areas and 19.6 times among those whose mothers obtained the diagnosis of syphilis after birth. The treponemal test showed positivity 3.2 times higher for the variable "having been diagnosed between 2007 and 2015" and 5.5 times higher for the variable "having been diagnosed with maternal syphilis in the postpartum period." CONCLUSION: This study shows that testing during prenatal care is essential for early diagnosis and prevention of syphilis complications.
ABSTRACT
RESUMO Objetivo Descrever o panorama da saúde auditiva infantil no Sistema Único de Saúde do estado de Sergipe. Método Estudo quantitativo e retrospectivo, composto por quatro etapas: 1) Busca no Cadastro Nacional de Estabelecimento de Saúde das instituições conveniadas ao Sistema Único de Saúde no estado de Sergipe que realizam serviços obstétricos e dos serviços que atuam na saúde auditiva; 2) Obtenção de dados de cobertura da Triagem Auditiva Neonatal (TAN), por meio do DATASUS (de 2012 a 2020); 3) Coleta de dados em prontuários das instituições com obstetrícia e/ou que realizam a TAN; e 4) Entrevista aos responsáveis das crianças em reabilitação auditiva. Os resultados foram sumarizados por meio de estatística descritiva (frequência absoluta e relativa, medidas de tendência central e de dispersão). Resultados Dos 29 estabelecimentos com obstetrícia, um realiza a TAN. Há dois Centros de Referência em Saúde Auditiva (CRSA) com habilitação para implante coclear e dois Centros Especializados em Reabilitação. De 2012 a 2020 a cobertura da TAN no estado foi inferior a 40% e quando realizada na maternidade, houve ausência de encaminhamentos para a realização do Potencial Evocado Auditivo de Tronco Encefálico (PEATE) e do diagnóstico audiológico. Observou-se cobertura considerável no CRSA com menor taxa de evasão para realizar PEATE e com taxa de diagnóstico de 4,8%. O tempo médio da TAN universal à reabilitação foi superior ao recomendado. Conclusão Existe necessidade de aumentar a cobertura da TAN, ajustar a rede de saúde auditiva para a articulação nos diferentes níveis de atenção e diminuir o tempo para identificação, diagnóstico e início da reabilitação.
ABSTRACT Purpose To describe the panorama of children's hearing health in the Unified Health System of the state of Sergipe. Methods A quantitative and retrospective study consisting of four steps: 1) Search the National Registry of Health Establishments of institutions affiliated to the Health Unic System in the state of Sergipe that perform obstetric services and hearing health services; 2) Collecting Neonatal Hearing Screening (NHS) coverage data through DATASUS (from 2012 to 2020); 3) Data collection from medical records of institutions with obstetrics and that perform NHS; and 4) Interview with the guardians of children undergoing auditory rehabilitation. The results were summarized using descriptive statistics (absolute and relative frequency, measures of central tendency, and dispersion). Results Only one out of the 29 establishments with obstetrics performs NHS. Two of the Hearing Health Reference Centers (HHRC) are qualified for cochlear implants and two Specialized Centers are qualified for Rehabilitation. From 2012 to 2020, NHS coverage in the state was less than 40%, and when performed in the maternity ward, there were no referrals for Brainstem Auditory Evoked Response (BERA) and audiological diagnosis. The HHRC showed considerable coverage and a lower evasion rate to perform BERA, with a diagnosis rate of 4.8%. The mean time from the NHS to rehabilitation was longer than recommended. Conclusion NHS coverage must be increased, adjusting the hearing health network to articulate the different levels of care, and reducing the time for identification, diagnosis, and start of rehabilitation.
