Background: China has had about 1.2 billion mobile-phone users, and this number continues to grow. However, mobile-health services (mHealth) are currently in the initial stage, and have not yet prevailed in China. Additionally, the prevalence of Parkinson's disease (PD) in China is 1700/100,000 (≥65 years). Indeed, these PD patients would benefit from mHealth to manage their disease. Therefore, we designed a study to determine attitudes toward smartphone applications (apps) for chronic condition self-management, and to discover the practicality of these apps among PD patients in China.Methods: We selected 204 participants with PD between 52 and 87 years old and surveyed their attitudes concerning the use of smartphone apps for chronic condition management via questionnaires.Results: Among the participants, 65.19% had smartphones. Among these smartphone users, 82.84% expressed a preference for using apps for PD management. This group tended to be younger and more frequent web users with higher education and better medication compliance, and they tended to have a longer PD course and worse conditions (P < 0.001, P = 0.001, P < 0.001, P = 0.041, P < 0.001, P = 0.013). Additionally, the willingness to apply apps for PD self-management was positively related to education (P < 0.001) and negatively related to age and PD course (P = 0.017, P < 0.001).Conclusion: In China, patients with PD have a generally positive attitude towards self-management through smartphone apps. Consequently, improving the coverage of smartphones with practical and handy apps is a promising strategy for PD self-management. [ABSTRACT FROM AUTHOR]

The 2019 novel coronavirus (2019-nCov) has caused increasing number of infected cases globally. This study was performed to analyze information regarding the transmission route and presence of viral nucleic acids on several clinical samples. Confirmed 2019-nCov-infected cases were identified in Dongyang and were treated according to guidelines for the diagnosis of 2019-nCov infection released by the National Health Commission. Information regarding the contacts that the infected people had was collected to determine whether it caused clustered cases. A series of successive nucleic acid examination of feces, oropharyngeal swabs, and sputum was also performed, and the results were analyzed. A total of 19 confirmed cases of 2019-nCov infection were identified in Dongyang, Zhejiang Province, China. Five cases showed severe symptoms, and the remaining ones showed mild manifestations. Ten cases infected from two asymptomatic individuals were clustered into two groups. Among 14 cases with consecutive nucleic acid test results, four patients showed positive results in feces after their negative conversion in oropharyngeal swabs. Asymptomatic individuals with the virus could cause 2019-nCov clustered cases, and the clustered cases may differ from sporadic cases on age and length of hospitalization. In addition, nucleic acids in feces last longer than those in oropharyngeal swabs. [ABSTRACT FROM AUTHOR]

Measures of traffic organization and traffic management in school zones, key protection areas for traffic safety, have been increasingly discussed by government administrations at all levels and researchers as well. Juveniles' trips occur frequently near school areas, especially in primary and secondary school zones. The sensitive topic of these vulnerable road users encountering traffic accidents tends to draw the whole society's attention. In this regard, the paper analyzed different traffic characteristics of 20 primary school zones in Beijing. With the starting point of traffic safety in the area, the paper divided these school zones by type, which was then verified preliminarily reliable and proper, by means of field measurement and driving simulation test, with speed characteristics as the major basis for judgment. By doing this, the authors look forward to providing a theoretical basis for carrying out measures of traffic organization and traffic management. [ABSTRACT FROM AUTHOR]

Objective: To analyze the effect and main gaps of each stage in the AIDS prevention cascade for men who have sex with men (MSM) provided in intervention projects supported by the China AIDS Fund for non-governmental organizations (CAFNGO) and provide suggestions to improve the quality of cascade services and project management. Methods: Data were collected through the CAFNGO management information system and field interviews to analyze the differences in the number of MSM receiving HIV testing and confirming tests, the newly reported patients, and the number of antiviral treatment (ART) referrals of newly established reported patients among different social organization service areas. A service chain chart was also drawn. Results: Between 2016 and 2020, 1 508 MSM intervention projects were funded by CAFNGO, including 1 183 234 MSM being mobilized to receive HIV testing. However, only 68.8% (1 183 234/1 719 139) of the testing capacity of social organizations was covered by these projects. As a result, 55 783 HIV-positive MSM were detected in preliminary screening, and only 86.6% (48 327/55 783) received confirming tests. The proportion of newly reported infections was 3.8% (45 347/1 183 234). The ratio of antiviral treatment (ART) referrals for newly reported patients between 2017 and 2020 was 89.8% (32 719/36 444). 75.8%(1 143/1 508) of total MSM intervention projects were implemented by community-based organizations (Non-registered civil affairs departments). In comparison, organizations registered in civil affairs departments took up 24.2% (365/1 508) of the total MSM intervention projects. No significant difference was noticed in the proportion of newly reported infected (3.8% and 3.8%) and the ratio of ART referrals (89.7% and 89.9%) between community-based organizations and registered organizations' projects. But these two proportions are significantly different between these two types of organizations in some areas in China. Conclusions: The AIDS prevention cascade established in CAFNGO has effectively promoted the early detection and treatment of infected MSM. However, CAFNGO needs more financial support to extend testing coverage for MSM. Meanwhile, confirmation testing for positives in preliminary screening and ART referrals needs to be improved for newly reported patients. In addition, various capacity building needs to be provided for different social organizations.

Objective: To understand the capacity building needs on social organizations providing HIV prevention and treatment services for female sex workers (FSW). Methods: Questionnaires and interview were conducted with the heads of social organizations participating in China AIDS Fund for Non-Governmental Organizations (CAFNGO) project 2017-2018. Data from the CAFNGO's information system were compiled and analyzed using Excel 2016 and SPSS 25.0 software. The distribution of social organizations, availability of funds, and social organizations' needs for capacity building were analyzed. Results: Nationwide, 184 social organizations were involved in project '2017-2018 CAFNGO's FSW field work'. Out of which, 156 answers were valid. Social organizations that participated in the implementation of fund projects were mainly concentrated in the western region, accounting for 44.0% (81/184), with Sichuan, Guangxi, and Yunnan being the majority. However, the eastern part received the most financial support. Social organizations expressed the highest demand for project data collection and analysis, accounting for 68.6% (107/156). Items on risk analysis, response, and quality control project ranked the second, accounting for 64.1% (100/156). Results showed that statistically significant differences were seen on capacity building needs among social organization leaders with different levels of training on management of planning and finance of the project ( χ 2 =5.78 ,P= 0.016; χ 2 =8.99, P= 0.003). Conclusions: Currently, the number of social organizations and the related fund provision concerning HIV prevention and control among FSWs were not consistent in China. Thus, it is necessary to encourage, guide, and support the development of social organizations and satisfy social organizations' needs on capacity-building and planning.

Objective: This study aims to survey medical staff's acceptance of online Mindfulness-Based Stress Reduction (MBSR) during the Novel Coronavirus Pneumonia (NCP), and to know some information of physical and emotional response of those medical staff who worked at the forefront of COVID-19, through the playback amount of the online MBSR training., Materials and Methods: Considering the working environment of medical staff in forefront of NCP, we designed and recorded MBSR audio album including 13 sessions, covering 24 hours of a day, then sent the album to medical staff who had been working in Wuhan, Hubei province, China. We collected the playback amount in each session on February 10th and February 24th, which were one week and three weeks after the album was finished., Results: On February 10th and February 24th, there were separately 5778 and 10640 times of broadcasting. The highest broadcasting frequency session was at 5:00 am, followed by 7:00 am. The least broadcasting frequency sessions were 17:00 pm and 19:00 pm. The broadcasting amount in the 6 periods of the night (from 21:00 pm to 7:00 am) was significantly higher than those in the daytime (from 9:00 am to 19:00 pm), with a statistical difference. The tendency of the amount of playback was consistent, which was not affected by the specific content of the mindfulness exercises., Conclusions: Online MBSR exercises were well accepted by medical staff in the COVID-19. It may help them relax and reduce the risk of stress reactions. During the NCP, medical staff may have different degrees of sleep and emotional problems, which need to be paid more attention to.

Objective: To analyze the clinical features of 3 cases of Takayasu arteritis(TA) with pulmonary cavities on chest computed tomography(CT). Methods: The clinical data of 3 TA patients with cavities on the chest CT who were admitted into Beijing Chaoyang Hospital were retrospectively analyzed. A literature search was performed with "Takayasu arteritis" and "pulmonary" as the key words in China Knowledge Resource Intergrated Database (CNKI) and Pubmed Database for publications from Jan 1, 2000 to Dec. 31,2017. The relevant literatures were reviewed. Results: Among the 3 patients, 2 were males and 1 was female, aging 49, 28 and 28 years, respectively. They presented with cough, fever and chest pain, and chest CT showed cavities, single or multiple, either with thick or thin wall, or wedge-shaped consolidation, residual stripes after being absorbed, and one case had pulmonary biopsy results which showed hemorrhagic infarction. They were all misdiagnosed before as pneumonia, pulmonary tuberculosis, pulmonary thromboembolism. After being treated by combination therapy of glucocorticoids and immunosuppressive agents, the disease improved significantly. A total of 777 cases with TA involving pulmonary arteries were reported, from which 13 cases with involvement of pulmonary parenchyma were described. Therefore total 16 cases including the 3 cases in this article were included for analysis. Twelve cases showed patchy or wedge-shaped ground-glass opacity and consolidation, and peripheral lung stripes remained after being absorbed. Two cases showed pleural effusion, and 4 cases showed cavities, 3 cases were misdiagnosed as pulmonary tuberculosis, 7 as pulmonary infection, and 5 as pulmonary thromboembolism. Conclusions: TA with pulmonary arteries involved is susceptible to be misdiagnosed and missed, and therefore, in patients with cough, hemoptysis, chest pain and cavities in pulmonary parenchyma, TA should be suspected. Early diagnosis and appropriate treatment can lead to a better prognosis.

Objective: The objective of this study was to investigate body composition redistribution at 3 months after radioactive iodine therapy (RAI)., Methods: Eighty patients with Graves' disease (GD) for RAI and 18 volunteers were recruited. All patients underwent thyroid status test and dual-energy x-ray absorptiometry at baseline and 3 months after RAI. According to the second thyroid status test, patients were divided into the following groups: A, with aggravated hyperthyroidism; B-1, with improved hyperthyroidism; B-2, with euthyroidism; and B-3, with hypothyroidism., Results: Total lean mass (LM) but fat mass (FM) and bone mineral content (BMC) of whole GD patients after RAI recovered to be not different with controls. Compared with baseline, in group A, FM in the left leg increased, and LM in left arm, right arm, trunk and total LM decreased (P<0.05). In B-2, FM in the head increased, and LM in the head, right arm, trunk and total LM increased (P<0.05). In B-3, FM in the right leg and total body fat percentage decreased, but FM in the head, android-to-gynoid fat ratio and body mass index increased (P<0.05); LM of all sites, weight and total mass increased (P<0.05); BMC in lumbar spine and left leg, and total BMC decreased (P<0.05). Body composition of unmentioned sites was retained after RAI in each group (P>0.05)., Conclusions: Replenishment of LM gets priority rather than FM and BMC during the first 3 months after RAI, and the increase in LM starts from the upper body; head is the regional site in which FM recovery occurs first.

A cluster-sampling, cross-sectional study was conducted for assessing the prevalence of Cryptosporidium infection in children less than 16 years of age from three villages, Dondian, Linshan, and Fuziyin, in rural Anhui in eastern China. Among 320 apparently healthy children less than 10 years of age from Dondian who had stool specimens collected, cryptosporidial oocysts were found in stools of three children from Dondian, and no positive specimens were found in 239 children studied from Linshan. In addition, a total of 610 serum samples from children in these three villages were tested for specific IgG antibody to Cryptosporidium with an enzyme-linked immunosorbent assay (ELISA) and the prevalence rates were 42.3%, 51.7%, and 57.5%, respectively, in Dondian, Linshan, and Fuziyin. Seroprevalence increased progressively with age. No detectable antibody was found in infants between two and six months of age, and seropositivity steadily increased after one year of age. Among 36 sera from adults 15-60 years of age without diarrheal illness in Huanglu villages of rural Chaohu, 50% (18 of 36) were positive. As expected, a good correlation was found in the specific IgG antibody between the paired serum specimens from 30 matched mother-neonates who showed transplacental transfer of IgG. However, little or no IgM antibody was seen in the neonates even though several mothers had a positive anticryptosporidial IgM enzyme-linked immunoassay result. Forty randomly selected serum samples from children less than four years of age in a similarly impoverished semiurban community in Fortaleza, Brazil, where the majority of households also have pit toilets and shared community water supplies and 172 serum samples from patients one month to 29 years of age admitted to the University of Virginia Hospital without diarrhea were also examined. In Fortaleza, almost all children acquired antibody by their second year of life, demonstrating the high prevalence of this infection. In rural Anhui, only about half the children were infected by 5-7 years of age. The overall prevalence rate (16.9%) of seropositivity among children and young adults in Virginia was much lower than in China and Brazil. These results indicate that cryptosporidial infection is ubiquitous, and is highly endemic in these impoverished communities. The difference between China and Brazil may reflect earlier weaning, hygiene practices, poorer water or sanitation, multiple siblings in family and geographic environment in Brazil.

During 5 consecutive years of 100 mm photofluorography, 21 cases of primary lung cancer were discovered among 211,881 checked subjects in 54 factories in the suburbs of Beijing. Detection rate was 9.9/100,000. In the male smokers 40 years old or over, who comprised 13.7% of all examined with a detection rate of 55.0/100,000. Among the 21 cases, peripheral cancer was 61.9%, in which 38.4% were stage I 69.2% were treated by surgical resection, much higher than that of the central type. It may be concluded that photofluorography in mass screening has a certain value in early detection of the peripheral lung cancer and the male smokers 40 years or over should be examined as a priority group.
