Measurement tools and rationality evaluation of clinical research coordinator's work ability and workload / 中国临床药理学与治疗学

AIM：To establish a project management tool to measure the working ability of research coordinators and the workload of clinical trial projects, and optimize medical institutions or clinical trial site management organization (SMO) allocation basis of clinical trial items by collecting the work stress and personal ability values of clinical coordinators. METHODS: Different words in the five major databases were searched and information on the work capacity and workload in the Subei People' s Hospital was collected. In addition, the paper analyzes the characteristics of coordinators working pressure source by SPSS26.0 statistical software and stability coefficient method. RESULTS: The study established the clinical research coordinator's personal ability - assessment tool (CRCPA-AT) and clinical trial project workload - assessment tool (CTPW-AT) to assess the coordinator's working ability and clinical trial workload. The two tools in this study were tested retrospectively in 61 coordinators and 144 clinical trials, 39 (66.1%) coordinators' projects were reasonably allocated, 18 (30.5%) coordinators were in the state of theoretical pressure and 12 (20.3%) coordinators had high actual pressure, which matched with the theoretical pressure. CONCLUSION: In this study, two scoring scales were established to quantify the working ability of the coordinators and the workload of clinical trial projects. Through the verification of the 61 coordinators and its management projects, the Likert5 point scoring method was used to analyze, more than 86.4% of the actual pressure of coordinators was consistent with the theoretical pressure quantified by the tool.

Single coronary artery originating from the right sinus Valsalva and ability to work

We present a case of a 56-year-old male electrician who was admitted to the hospital with atrial fibrillation, atypical chest pain and dyspnea. He gave a history that on the morning he had working for almost 4 hours carrying out various activities with considerable physical effort. After cardioversion, conventional coronary angiography revealed a suspect of single coronary vessel (SCA) arising from the right sinus of Valsalva. The patient underwent multislice computed tomography that showed a SCA arising from the right sinus Valsalva and dividing in Right Coronary Artery (RCA) and Left Main coronary artery (LM). The finding of posterior course of the LM without atherosclerotic has proved crucial for the expression of an opinion of working capacity even with limitation.

Comparação da percepção de fadiga e de capacidade para o trabalho entre trabalhadores têxteis de empresas que se encontram em diferentes estágios de responsabilidade social empresarial no estado de São Paulo, Brasil / Comparison of fatigue and workability among textile workers of companies in different stages of corporate social responsibility in the state of São Paulo, Brazil

OBJETIVOS: Comparar as características demográficas e as percepções da capacidade para o trabalho, fadiga e condições de trabalho entre trabalhadores de indústrias têxteis que estejam em diferentes estágios de responsabilidade social empresarial (RSE). MÉTODOS: Em estudo transversal, 126 trabalhadores de três empresas e cinco fábricas responderam a questionário de caracterização demográfica, condições e estilos de vida, a autoavaliações sobre fadiga, condições de trabalho e capacidade para o trabalho. As empresas foram classificadas em dois grupos de pontuação de indicadores de RSE (o grupo um de menor pontuação e o grupo dois de maior pontuação), com base nas respostas dadas em questionário específico. RESULTADOS: Não foram encontradas diferenças (p > 0,05) nos resultados de capacidade para o trabalho, fadiga e na maior parte dos dados demográficos obtidos entre os trabalhadores dos dois grupos. As melhores condições de trabalho, no grupo de maior pontuação (p = 0,008), deveram-se principalmente ao fornecimento de refeições nas fábricas. CONCLUSÕES: O desenvolvimento e a implementação de projetos de RSE não implicam, necessariamente, em melhores condições de trabalho ou em percepções dos trabalhadores de menor fadiga ou maior capacidade para o trabalho, em relação a empresas que não dispõem desses projetos. Por tratar-se de estudo transversal com população reduzida e como a capacidade para o trabalho pode diminuir com o envelhecimento do trabalhador novos estudos, preferencialmente longitudinais, deverão ser realizados, com populações maiores.

Comparisons of left ventricular systolic and diastolic times in exercise between trained and untrained men / 体力科学

The systolic time intervals (STI's) and the diastolic time (DT) as functions of the RR interval during exercise were proved to be described by cubic regression equations that converge to the origin of the coordinates. Using the equations, we compared I) the systolic time and DT of trained and untrained men, and II) examined the relations between parameters of STI's. I) Forty healthy male subjects aged 19-22 years old were divided into three groups, i, e., 8 long distance runners (group LD), 16 men with relatively high fitness (group A) and 16 men with relatively low fitness (group B) . They performed submaximal exercise test using a cycle ergometer for measuring the time of electromechanical systole (QS<SUB>2</SUB>) and DT. After test, maximal exercise test was conducted to determine the maximal heart rate (HRmax) in each subject. Means±SD of the minimum QS<SUB>2</SUB> and the minimum DT of the 40 subjects predicted from the regression equations at the HRmax were 209.7±12.5 and 108.2±15.6 ms, their ratio being about 2: 1. The QS<SUB>2</SUB> was significantly shorter, whereas DT was longer in the group LD than in the groups A and B at the HR of more than 120 bpm. II) Ten healthy male subjects aged 19-22 years old performed submaximal exercise to clarify the relations between any two of QS<SUB>2</SUB>, the left ventricular ejection time (LVET) and the preejection period (PEP) at the same HR: there were positive and negative significant correlations between QS<SUB>2</SUB> and LVET, and between LVET and PEP, respectively, at the HR of more than 100 bpm. These results reveal that, when the HR is increased in exercise, the left ventricular systolic time (QS<SUB>2</SUB>) is shortened while the diastolic time is lengthened for the subjects trained as long distance runners. The shortening of the systolic time is mainly caused by shortening of LVET. The changes in the systolic and diastolic times suggest that contractility of cardiac muscle is enhanced during exercise of above moderate intensity after an extensive period of the aerobic training.
