ObjectiveTo assess the correlation of WHO pathological classification and Masaoka stage of thymomas with its prognosis.MethodsA total of 468 patients with thymomas who received surgeries during 2009-2019 in Huashan Hospital, Fudan University, were collected. There were 234 males and 234 females with an average age of 21-83 (49.6±18.7) years. A total of 132 patients underwent video-assisted thoracic surgery (VATS) and 336 patients underwent thymectomy with median sternal incision. The follow-up time was 5.7±2.8 years. The clinical data of the patients were analyzed.ResultsThe amount of intraoperative bleeding was 178.3±133.5 mL in the median sternal incision group, and 164.8±184.1 mL in the VATS group (P=0.537). The operative time was 3.3±0.7 h in the median sternal incision group and 3.4±1.2 h in the VATS group (P=0.376). Postoperative active bleeding, phrenic nerve injury and chylothorax complications occurred in 8 patients, 9 patients and 1 patient in the VATS group, respectively, and 37 patients, 31 patients and 7 patients in the median sternal incision group, respectively. There was no statistical difference between the two groups (P=0.102, 0.402, 0.320). The 5-year cumulative progression free survival (PFS) rates of patients with WHO type A, AB, B1, B2, B3 and C thymomas were 100.0%, 100.0%, 95.7%, 81.4%, 67.5% and 50.0%, respectively (P<0.001). The 5-year PFS rates of patients with Masaoka stageⅠ-Ⅳ thymomas were 96.1%, 89.2%, 68.6% and 19.3%, respectively (P<0.001). The 5-year PFS rate was 87.3% in patients with myasthenia gravis (MG) and 78.2% in patients without MG (P<0.001). The 5-year PFS rates of patients with different surgeries were 82.4% and 83.8%, respectively (P=0.904). ConclusionWHO pathological classification and Masaoka stage have significant clinical prognosis suggestive effect. Thymoma patients combined with MG have better prognosis, which suggests early diagnosis and treatment of thymoma are important.
ObjectiveTo evaluate the quality of life of residents in stricken area five years after Wenchuan earthquake, so as to explore the main influential factors such as gender, age, ethnic group, marriage status and the extent affected by the earthquake. MethodsUsing WHOQOL-BREF, 500 residents from Hanyuan county in Sichuan province were assessed in order to analyze their life quality and related factors. ResultsThe score on the overall WHOQOL-BREF and the level of each factor were significantly lower than the score on the normal people (P < 0.001). Male score in the factor of social relations significantly higher than female (t=3.963, P < 0.001). The overall score and the score of social factor were significantly lower in the minor than in the adults (t=-2.667, P < 0.01; t=-19.287, P < 0.001). And the quality score of social relationship was significantly lower in the single than in the married and cohabiting couples (P < 0.001; P < 0.01). ConclusionThe quality of life of residents in stricken area five years after Wenchuan earthquake was significantly lower than the national norm. There are significant differences in terms of gender, age, marriage status and earthquake damage on social relations. Steady intimate relationships with others help improve the quality of life of residents in stricken area. Besides, compared those with average damage or no damage, the residents with serious damage are relatively worse in the overall quality of life as well as environmental conditions.
Advancing patient safety is one of the most important strategies developed by WHO. The following paper outlined the main content, aims and goals of WHO the second global patient safety challenges “ Safe surgery saves lives” as well as discussed the importance of communication between surgeons and patients.
ObjectivesTo analyze the development of acupuncture registered trials based on WHO international clinical trial registration platform (ICTRP) in the past 5 years.MethodsWHO ICTRP database was electronically searched to collect acupuncture-related clinical trials registered from January 1st, 2014 to December 31st, 2018. Two reviewers independently screened items, extracted data, and descriptive analysis was performed for the included trials.ResultsThe results showed that there were 1 556 registered clinical trials on acupuncture, and the most registered year was 2017. China was in the main country in applying for acupuncture-related clinical trials, however, the most registered unit was Kyung Hee University in Korea. The trials were mainly interventional research, mostly used randomized, blinded methods, and design modes were mainly based on parallel trials. In clinical trial phase, the majority were in the clinical trial period of treatment of new technologies. The field of clinical research was expected to be on pain in the future.ConclusionsAlthough acupuncture research is currently in a good stage of development, it should still value on the quality and innovative training of relevant trials, strengthen Chinese ties with other countries, focus on regional, domestic and international cooperation, expand research types, and enhance acupuncture applicability.
ObjectiveTo assess the accuracy of CT features of lung nodules (≤3 cm) in predicting the accuracy of the pathological subtype and degree of infiltration of adenocarcinoma. Methods We retrospectively analyzed the clinical data of 333 patients with non-cavitary pulmonary nodules diagnosed as adenocarcinoma by surgery and pathology in the China-Japan Friendship Hospital from 2011 to 2018, including 108 males and 225 females, aged 16-82 (59.57±10.16) years. The basic clinical data and CT characteristics of the patients were recorded. ResultsWhen the average CT value was ≥−507 Hu, the maximum diameter of the lung window was ≥14.5 mm, and the solid component ratio was ≥5.0%, it indicated more likely the invasive adenocarcinoma (IAC). The higher the average CT value of the nodule, the larger the maximum diameter of the lung window, and the more solid components, the higher the degree of infiltration. CT morphological features (including burrs, lobes, vascular signs, bronchial signs, pleural stretch or depression signs) were more common in IAC. Among them, burrs were more common in acinar adenocarcinoma and papillary adenocarcinoma. In invasive adenocarcinoma, the higher the risk of recurrence of the pathological subtype, the greater the average CT value. When the average CT value of IAC was >−106 Hu, and the proportion of solid components was ≥70.5%, the histological subtypes were more inclined to micropapillary/solid predominant adenocarcinoma. Conclusion The evaluation of CT features of lung nodules can improve the predictive value of histopathological types of lung adeno- carcinoma, thereby optimizing clinical treatment decisions and obtaining more ideal therapeutic effects.
Pulmonary adenocarcinoma in situ is reclassified as precursor glandular lesions in the fifth edition of WHO classification of thoracic tumours, causing widespread attention and heated debate among domestic thoracic oncologists, radiologists, pathologists and surgeons. We would like to comment on the topic and make a few suggestions on the management of pulmonary nodule during lung cancer screening. We are open to all suggestion and welcome debates.
In order to help Chinese guideline developers, clinicians, health policy makers and other relevant researchers fully understand and make appropriate use of World Health Organization (WHO) guidelines, Chinese GRADE Center and Guidelines Review Committee of World Health Organization (WHO-GRC) have written a series of papers about development methods, review principles and the structure and content of WHO guidelines. This is the second paper of this series introducing the composition, main work and functions of WHO-GRC.
The World Health Organization (WHO) released the WHO 2020 guidelines on physical activity and sedentary behaviour in November 2020. Compared with the 2010 WHO guidelines, this guideline has incorporated more extensive medical evidence and made targeted recommendations for special populations. The main content includes physical activity and sedentary behaviour advice for children and adolescents, adults, older adults, pregnant and postpartum women, people with chronic conditions, and disability. This review will interpret the 2020 WHO guidelines in detail.
