BACKGROUND: Chinese and contemporary Western medical practices evolved on different cultures and historical contexts and, therefore, their medical knowledge represents this cultural divergence. Computerization of traditional Chinese medicine (TCM) is being used to promote the integrative medicine to manage, process and integrate the knowledge related to TCM anatomy, physiology, semiology, pathophysiology, and therapy. METHODS: We proposed the development of the SuiteTCM software, a collection of integrated computational models mainly derived from epidemiology and statistical sciences for computerization of Chinese medicine scientific research and clinical practice in all levels of prevention. The software includes components for data management (DataTCM), simulation of cases (SimTCM), analyses and validation of datasets (SciTCM), clinical examination and pattern differentiation (DiagTCM, TongueTCM, and PulseTCM), intervention selection (AcuTCM, HerbsTCM, and DietTCM), management of medical records (ProntTCM), epidemiologic investigation of sampled data (ResearchTCM), and medical education, training, and assessment (StudentTCM). DISCUSSION: The SuiteTCM project is expected to contribute to the ongoing development of integrative medicine and the applicability of TCM in worldwide scientific research and health care. The SuiteTCM 1.0 runs on Windows XP or later and is freely available for download as an executable application. © 2013 Arthur de Sá Ferreira. Source

Background: COPD is a major cause of death and morbidity worldwide, and is characterized by persistent airflow obstruction. The evaluation of obstruction is critically dependent on sensitive methods for lung-function testing. A wide body of knowledge has been accumulated in recent years showing that these methods have been significantly refined and seems promising for detection of early disease. Objectives: This review focuses on research on pulmonary function analysis in COPD performed in Brazil during this century. Materials and methods: The literature was searched using a systematic search strategy limited to English language studies that were carried out in Brazil from the year 2000 onward, with study objectives that included a focus on lung function. Results: After we applied our inclusion and exclusion criteria, 94 articles addressed our stated objectives. Among the new methods reviewed are the forced-oscillation technique and the nitrogen-washout test, which may provide information on small-airway abnormalities. Studies investigating the respiratory muscles and thoracoabdominal motion are also discussed, as well as studies on automatic clinical decision-support systems and complexity measurements. We also examined important gaps in the present knowledge and suggested future directions for the cited research fields. Conclusion: There is clear evidence that improvements in lung-function methods allowed us to obtain new pathophysiological information, contributing to improvement in our understanding of COPD. In addition, they may also assist in the diagnosis and prevention of COPD. Further investigations using prospective and longitudinal design may be of interest to elucidate the use of these new methods in the diagnosis and prevention of COPD. © 2016 Lopes and Melo. Source

Purpose: The Metastatic spinal cord compression (MSCC) secondary to lung cancer (LC) has worse prognosis when compared to MSCC related to other solid tumors. The purpose of this study is to identify the survival time and the prognostic factors in the MSCC secondary to LC. Methods: A systematic review of the literature has been carried out. Studies published between January 2005 and March 2015 were identified through the electronic database PubMed and LILACS. Two independent reviewers selected the articles. Results: 7 studies were identified, which met the inclusion criteria, involving 1010 patients. The survival in 6 and 12 months ranged between 18 and 61 %, and between 3.8 and 32 %, respectively. The median survival ranged between 2.8 and 9 months. The variables related to the survival improvement were: female, performance status 1 or 2, pre-radiotherapy and postoperative ambulatory status, absence of bone metastases and visceral metastases, interval from cancer diagnosis to spinal metastases or radiotherapy of MSCC >15 months, slower (>7 days) development of motor deficit, and the neurological status at the postoperative. Conclusions: The prognosis of the MSCC secondary to LC was poor. Considering the small number of studies identified, further research is needed to identify prognostic factors that are independent of the MSCC secondary to LC. © 2015, Springer-Verlag Berlin Heidelberg.

Chinese Medicine

Background: Hypertension is a clinical condition that manifests target-organ damage (TOD) with symptoms. This study investigates the association between Zangfu patterns and symptomatic manifestations of TOD. Methods: Datasets with manifestations of Zangfu patterns (Liver-fire blazing upwards; Kidney-yin deficiency and Liver-yang rising; obstruction of phlegm and dampness of Heart/Liver/Gallbladder; qi and blood deficiency leading to Liver-yang rising; Kidney-yin/yang deficiency) and TODs (cerebrovascular, heart and kidney) were compiled from literature. The Pattern Differentiation Algorithm was used to test and to determine diagnostic accuracy with these datasets. A questionnaire was developed from datasets and applied to 43 subjects newly diagnosed with hypertension. Pattern differentiation was performed and the results were statistically analyzed for association between descriptions of patterns and TOD. Results: The observed diagnostic accuracy, sensitivity and specificity were 98.0%, 96.2% and 99.8% respectively. Similarity between patterns and TOD datasets was mostly negligible. Twelve manifestations demonstrated high prevalence, namely red tongue (81.4%), headache (72.1%), irritability (67.4%), palpitation (60.5%), blurred vision, insomnia and mental fatigue (58.1%), frequent nocturnal urination, numbness in feet and hands, shortness of breath (55.8%), and heavy limbs sensation, wiry pulse (51.2%). No significant association was found between blood pressure variables (systolic, diastolic, mean, pulse pressure) and manifestations. Conclusion: Zangfu patterns are associated with clinical manifestations of TOD. Manifestations associated patterns indicate morbid conditions to be secondary to hypertension rather than simple blood pressure. © 2011 Luiz et al; licensee BioMed Central Ltd. Source

OBJECTIVE: The aim of this work is to develop and implement the SimTCM, an advanced computational model that incorporates relevant aspects from traditional Chinese medicine (TCM) theory as well as advanced statistical and epidemiological techniques for simulation and analysis of human patients.METHODS: SimTCM presents five major attributes for simulation: representation of true and false profiles for any single pattern; variable count of manifestations for each manifestation profile; empirical distributions of patterns and manifestations in a disease-specific population; incorporation of uncertainty in clinical data; and the combination of the four examinations. The proposed model is strengthened by following international standards for reporting diagnostic accuracy studies, and incorporates these standards in its treatment of study population, sample size calculation, data collection of manifestation profiles, exclusion criteria and missing data handling, reference standards, randomization and blinding, and test reproducibility.RESULTS: Simulations using data from patients diagnosed with hypertension and post-stroke sensory-motor impairments yielded no significant differences between expected and simulated frequencies of patterns (P=0.22 or higher). Time for convergence of simulations varied from 9.90 s (9.80, 10.27) to 28.31 s (26.33, 29.52). The ratio iteration profile necessary for convergence varied between 1:1 and 5:1.CONCLUSION: This model is directly connected to forthcoming models in a large project to design and implement the SuiteTCM: ProntTCM, SciTCM, DiagTCM, StudentTCM, ResearchTCM, HerbsTCM, AcuTCM, and DataTCM. It is expected that the continuity of the SuiteTCM project enhances the evidence-based practice of Chinese medicine. The software is freely available for download at: http://suitetcm.unisuam.edu.br.
