RESUMEN
BACKGROUND: The coronavirus disease 2019 (COVID-19) has been a worldwide public health emergency that has put great pressure on medical workers and the medical system. General Practitioners (GPs) played an important role in controlling the epidemic, and GP trainees also took an active part in this approach. This study was to explore Chinese GP trainees' career perspectives after COVID-19. METHODS: We conducted a qualitative research study which included 12 GP trainees from three teaching hospitals in China. Semi-structured telephone interviews were conducted. Grounded theory and thematic analysis were used to code the data and identify categories and factors. RESULTS: Eleven participants chose to continue a GP career after COVID-19, and nearly half of the participants strengthened their determination to dedicate themselves to this career. Only one participant decided to change the career choice because of interest in another specialty. Four main themes influencing GP trainees' perceptions of career development after COVID-19 emerged from the interviews: changes of GPs' work content in COVID-19, challenges of being a GP, psychological changes of the career, how to provide better primary care. Although some negative psychological changes existed, most of participants were inspired by role models and medical colleagues. They had more in-depth understanding of GPs' role and responsibility during COVID-19, and exhibited intensions for self-improvement in career development, especially in public health education and self-protection in preventing infectious diseases. In addition, the wide use of telemedicine provided a new work way for GP trainees. However, challenges, such as increased workloads, low income, lack of resources in primary medical institutions, and distrust of GPs are faced by trainees during the outbreak. CONCLUSIONS: Overall, no substantial changes were seen in the career choice of GP trainees after COVID-19 outbreak. However, they were inspired and had an in-depth understanding about the GP's work and responsibility during an epidemic. Owing to the challenges faced by the GPs, measures are needed to improve the GP education and work environment in the training phase.

Inflammatory bowel disease (IBD), mainly including ulcerative colitis and Crohn's disease, imposes a huge medical and economic burden worldwide. Recently, the diagnosis, treatment, and surveillance of IBD have advanced rapidly, which has changed the epidemiology, cancer risk, and surgery risk of IBD. Here, we reviewed the recent literature on the epidemiology, IBD-related cancer, and IBD-related surgery. We created a choropleth map to show the worldwide incidence trend for Crohn's disease and ulcerative colitis. We also found that the cancer risk and surgery risk of IBD are declining and discussed some risk factors associated with them. Based on the recent trend, we proposed several suggestions and hoped to reduce the global burden of IBD as far as possible.
RESUMEN
Objective: To investigate the association between dietary and some other environmental factors and the risk of inflammatory bowel diseases (IBD) in Chinese population. Materials and methods: A multicenter case-control study was conducted involving 11 hospitals across China. A total of 1,230 subjects were enrolled consecutively, and diet and environmental factor questionnaires were collected. IBD patients were matched with healthy controls (HC) using propensity-score matching (PSM) at a 1:1 ratio with a caliper value of 0.02. Multivariate conditional logistic regression analyses were performed to evaluate the associations between diet, environmental factors, and IBD. Results: Moderate alcohol and milk consumption, as well as daily intake of fresh fruit, were protective factors for both Crohn's disease (CD) and ulcerative colitis (UC). Conversely, the consumption of eggs and chocolate increased the risk of IBD. Outdoor time for more than 25% of the day was a protective factor only for CD. In eastern regions of China, CD patients had higher egg consumption and less outdoor time, while UC patients consumed more chocolate. IBD patients from urban areas or with higher per capita monthly income consumed more fruit, eggs, and chocolate. Conclusions: This study reveals an association between specific foods, outdoor time, and the emergence of IBD in the Chinese population. The findings emphasize the importance of a balanced diet, sufficient outdoor time and activities, and tailored prevention strategies considering regional variations.

OBJECTIVE: To explore the understanding of refractory gout in Chinese rheumatologists. METHODS: We conducted an anonymous survey of rheumatologists attending an annual national academic conference on rheumatism. RESULTS: Of the 910 rheumatologists who completed the questionnaire, 751 (82.5%) had received relevant continuing medical education (CME). Of these, 140 (18.6%) rheumatologists did not select xanthine oxidase inhibitors as the first treatment for patients with chronic tophaceous gout. Of all respondents, 113 (12.4%), 251 (27.6%) and 324 (35.6%) prescribed incorrect maximum doses of allopurinol, febuxostat and benzbromarone, respectively; this tendency was more pronounced in the non-CME group. Most rheumatologists agreed that complications and comorbidities increased the difficulty of gout management and considered the term refractory gout to describe those cases with uncontrolled symptoms, unmet treatment targets or non-shrinkage of tophi after standardized drug treatment. Moreover, 62.8% (472/751) of specialists considered that a diagnosis of refractory gout was appropriate for patients whose lifestyle and compliance failed to improve despite adequate education and regular urate-lowering therapy. CONCLUSIONS: Incorrect and inadequate drug therapy may contribute to some cases of refractory gout, especially in physicians without CME. An emphasis on non-drug therapy and the management of comorbidities and complications may reduce cases of refractory gout.

BACKGROUND: Previous studies have suggested that the possible relationship between serum uric acid (SUA) and testosterone. However, the results of previous studies are controversial and there is limited evidence examining the relationship between SUA and testosterone in a general US population of men. The objective of this study is to explore the correlation of SUA and testosterone among adult males from the US. METHODS: Data from the National Health and Nutrition Examination Survey 2011-2016 were used, including a total of 7,796 male participants aged 18 years or older and excluding those lacking serum testosterone and uric acid data. Clinical characteristics of the participants among different SUA groups and testosterone groups are compared. Univariate and multivariate linear regression analyses were applied to evaluate the association between SUA and testosterone. RESULTS: We found an inverse association between SUA and testosterone after fully adjusted the potential confounding factors in general US adult males. In the multivariate linear regression analysis, we found that increasing age (estimate testosterone percent difference: -0.20% per year, P<0.01), uric acid (estimate testosterone percent difference: -4.40% per md/dL, P<0.01) and BMI (estimate testosterone percent difference: -2.86% per kg/m2, P<0.01) were associated with declining serum testosterone. This association remained significant in sensitivity analysis, while in the stratified analysis, above association was not significant in men with diabetes or aged 65 and over. CONCLUSIONS: SUA levels might be negatively associated with serum testosterone in adult males.
RESUMEN
In this study, the CuInS2/ZnS core/shell quantum dots (QDs) were prepared via simple and environmentally friendly solvothermal synthesis and were used as phosphors for white light-emitting diodes (WLEDs). The surface defect of the CuInS2 core QDs were passivated by the ZnS shell by forming CuInS2/ZnS core/shell QDs. By adjusting the Cu/In ratio and the nucleation temperature, the photoluminescence (PL) peak of the CuInS2 QDs was tunable in a range of 651-775 nm. After coating the ZnS layer and modifying oleic acid ligands, the PL quantum yield increased to 85.06%. The CuInS2/ZnS QD powder thermal stability results showed that the PL intensity of the QDs remained 91% at 100°C for 10 min. High color rendering index values (CRI, 90) and correlated color temperature of 4360 K for the efficient WLEDs were fabricated using CuInS2/ZnS QDs and (Ba,Sr)2SiO4:Eu2+ as color converters in combination with a blue GaN light-emitting diode chip.
RESUMEN
Giant cell arteritis (GCA) is the most common vasculitis in elderly, with ischemic and constitutional symptoms caused by vascular involvement and systemic inflammation. Early initiation of therapy results in prompt remission, while patients may still experience flares or severe complications during glucocorticoid tapering. This study was to identify the characteristics of Chinese GCA patients with different prognosis.Ninety-one patients diagnosed with GCA in Peking Union Medical College Hospital in the last 20 years were followed up. Those who were lost to follow up or were followed up for less than 1 year were excluded. According to the prognosis, patients were divided into the group of favourable prognosis (patients who sustained disease remission for over 1 year) and unfavorable prognosis (patients who had relapses or severe complications). Clinical data at disease onset and after treatment were collected and analysed between the 2 groups.Thirty-seven patients with favourable prognosis and 40 patients with unfavourable prognosis were admitted into the study. Fever as an onset symptom was less common in favourable group (P=.016). As for presentations of GCA, fever, tenderness and abnormal pulsation of temporal artery and jaw claudication were less frequently observed in patients with favourable prognosis (P=.029, .049, .043, respectively). At onset, medium-size arteries were affected more in unfavorable prognosis group (Pâ=â.048), and involvement of branches below the aortic arch were more common in favorable prognosis group (Pâ=â.034). Erythrocyte sedimentation rate in group of favourable prognosis were significantly lower after treatment (Pâ=â.041). Compared with healthy subjects, GCA patients had increased monocytes and decreased lymphocytes at disease onset (Pâ<â.01). Monocyte counts were higher in patients with favourable prognosis at disease onset (Pâ=â.043), while no significant differences were seen between the 2 groups after treatment. Lymphocyte counts were lower in patients with unfavourable prognosis (Pâ=â.014) after treatment.Complete blood count may reflect the disease status of GCA. Little change in monocyte during treatment and lower lymphocytes after treatment may serve as potential predictors of unfavourable clinical prognosis.

To evaluate job burnout and its impacts on mental health among clinical residents in a 3-year standardized residency training program in China.This cross-sectional study was conducted among all residents in the Department of Internal Medicine of the Peking Union Medical College Hospital in August 2017. Job burnout and depressive symptoms were assessed using the Maslach Burnout Inventory-General Survey and the Center for Epidemiological Survey, Depression, respectively.Among the 159 residents who completed the survey, comprising 69 who had graduated from 8-year medical schools and 90 from 5-year schools, the rate of job burnout was 62.2% (100/159) and the rate of depression was 28.3% (45/159). Rates of job burnout and depression in residents completed different years of training showed no significant difference. Rate of job burnout was significantly higher among graduates of 5-year medical schools (76.7%) than among those of 8-year schools (44.9%, Pâ<â.001). Pearson chi-squared test revealed a significant correlation between depression and job burnout (Pâ<â.001). Multiple logistic regression revealed a significant correlation between job burnout and attendance at 5- or 8-year medical schools (Pâ=â.044).Job burnout may be more frequent among graduates from 5-year medical schools than among those from 8-year schools.

BACKGROUND: The symptoms of giant cell arteritis (GCA) and polymyalgia rheumatica (PMR) frequently overlap in the elderly. Whether there are differences in clinical features or prognosis between GCA patients with or without PMR remains unknown. AIMS: To identify differences in clinical manifestation and prognosis between Chinese GCA patients with or without PMR. METHODS: A retrospective study of patients diagnosed with GCA in Peking Union Medical College Hospital (PUMCH) during the last 20 years was conducted. Clinical data was collected and analyzed accordingly, and follow-up was performed. RESULTS: A total of 50 patients had PMR, while 41 patients did not, with no significant differences in age, gender, and disease course between the two groups. GCA patients with PMR presented with higher risks of family history of malignancy (p = 0.048). Patients without PMR had higher proportion of hearing loss (p = 0.006), ANCA positive (p = 0.024), and abnormal imaging findings illustrating the involvement of arteries under aortic arch (p = 0.018). Before treatment, total lymphocyte counts in patients without PMR were lower than those with PMR, and monocyte counts in both groups were higher than normal. Acute phase reactants in patients without PMR were higher than the other group. No significant differences were found in prognosis during follow-up. CONCLUSIONS: GCA patients with or without PMR have different clinical characteristics. Patients with PMR present myalgia or arthralgia more frequently, while those without PMR have higher inflammatory markers, lower lymphocyte counts, and wider involvement of arteries under aortic arch.

Auditory manifestations has rarely been mentioned in studies concerning giant cell arteritis (GCA). This study explores the proportion of hearing loss (HL) in Chinese GCA patients and investigates the differences in clinical features between GCA patients with and without HL.The study retrospectively reviewed the clinical records of 91 patients diagnosed with GCA at Peking Union Medical College Hospital (PUMCH) from November 1998 to October 2017. GCA diagnoses were reconfirmed according to the American College of Rheumatology 1990 criteria. Diagnosis of HL was made based on a patient's symptoms combined with physical examination or ear-nose-throat (ENT) audiometry tests. Subgroup analysis was conducted according to the occurrence of HL.Totally 23 patients (25.3%) had HL. A higher percentage of males (65.2% vs 38.2%, pâ=â0.025) was seen in HL group. Symptoms such as headache (91.3% vs 61.2%, pâ=â0.011), visual loss (56.5% vs 32.4%, pâ=â0.039) and CNS symptoms (39.1% vs 17.6%, pâ=â0.035) were more frequent in HL group. Moreover, they were more likely to have smoking history (pâ=â0.019), lower lymphocyte count (pâ=â0.049), positive ANA or APL (pâ=â0.047, pâ=â0.017) or negative biopsy results (pâ=â0.015). Symptom like myalgia (26.1% vs 66.2%, pâ=â0.001) as well as comorbid disease like coronary artery disease (pâ=â0.037) and hypertension (pâ=â0.040) was more frequent in patients without HL. Either C-reactive protein (90.91â±â65.86 vs 76.05â±â61.15âmg/L, pâ=â0.347) or erythrocyte sedition rate (83.04â±â29.61 vs 93.69â±â26.78âmm/h, pâ=â0.136) was high in both groups but the differences were not significant. Meanwhile, no significant differences were found in age, disease course, vascular involvement or prognosis between the two groups. Unilateral HL tended to happen at the same side with unilateral headache, visual loss, scalp tenderness or jaw claudication.HL is probably not rare in GCA patients and is more frequently to be seen in patients presented with headache, visual loss or CNS symptoms. Differentiation of HL is necessary for specialists and GCA should be considered as a potential diagnosis especially in HL patients with high inflammatory markers. Auditory assessment should be conducted in GCA management.
