ObjectiveTo characterize the prevalence and epidemic situation of imported malaria cases in Songjiang District of Shanghai from 2013 to 2022， and to provide evidence for malaria prevention and control. MethodsRelated data were collected and analyzed， including malaria cases， blood testing of febrile patients， and mosquito surveillance in Songjiang from 2013 to 2022. ResultsA total of 13 002 febrile patients in Songjiang were tested for plasmodium parasites from 2013 to 2022， among which 18 malaria cases were confirmed， including 17 cases of falciparum malaria and 1 case of ovale malaria. Moreover， a total of 36 malaria cases were notified in Songjiang through the National Notifiable Disease Reporting System from 2013 to 2022， including cases reported from Songjiang District and other districts or provinces with physical addresses in Songjiang. Of them， there were 31 cases of falciparum malaria， 2 cases of vivax malaria， 2 cases of ovale malaria and 1 case of quartan malaria. The gender ratio of male to female cases was 17∶1， and the majority was young and middle aged. In addition， 35 cases were imported from Africa and 1 case from southeast Asia； 34 cases were migrant workers， and 2 cases were travellers abroad； 17 cases were found and reported in Songjiang， 15 cases were reported from other districts of Shanghai， and 4 cases were reported from other provinces； 27 cases were treated in Shanghai， 3 cases were treated in other provinces and 6 cases were treated with self-provided antimalarial drugs. Mosquito surveillance in Songjiang showed that density of Anopheles sinensis was extremely low. ConclusionNo indigenous malaria case has been notified in Songjiang since 2008. Malaria surveillance on migrant workers remains the focus of malaria prevention and control. Furthermore， achievement of malaria elimination in Songjiang should be continually enhanced to avoid potential further transmission of imported malaria.

INTRODUCTION: Advanced breast cancer (ABC) remains common in Singapore. In 2019, 22.1% of breast cancer patients presented with ABC in our institution. Despite increasing affluence and the advent of national mammographic screening, the incidence of ABC has not changed significantly. This suggests inherent differences in women who present late. We aim to explore the socio-economic background, knowledge and attitudes of women who present with ABC. METHODS: Between December 2013 and July 2015, 100 patients who presented consecutively with ABC in a tertiary institution in Singapore were recruited to participate in an interviewer-led questionnaire exploring psychosocial and economic issues. RESULTS: Among the 100 patients, 63 and 37 presented with stages 3 and 4 breast cancer respectively. Median age was 57 (27-86), 52% had at least secondary education, 53% had no formal employment and 71% were married; 88% were aware of breast cancer symptoms, 82% were aware that mammography can help detect cancer, 82% believed that current treatment modality for breast cancer is effective, 96% had never undergone a mammography and 52.9% felt mammograms were unnecessary. A total of 64% presented symptomatic from the breast tumour, with a median duration of 3 months. Many of the patients were aware of breast cancer symptoms and the utility of mammography. However, a group of patients did not comply with screening. This may be due to poor understanding about breast screening and detection in its asymptomatic phase. CONCLUSION Further public education to improve understanding of breast cancer and screening mammography may help to improve rates for earlier detection of breast cancer.

Objective:To understand the status quo of primary medical and health services for home aged dementia patients in Weifang from the perspective of medical service providers. And to provide suggestions for improving the primary medical services and community care for home aged dementia patients.Methods:A semi-structured in-depth interview was conducted with 26 primary medical and health care workers in the primary medical and health services of home patients with senile dementia, and the interview data were summarized and extracted by content analysis method.Results:Four themes were extracted according to the primary medical and health services for home aged dementia patients. Theme 1: less chance to contact with dementia patients, and the understanding of the disease is biased. Theme 2: limited medical services and no targeted services. Theme 3: receive less relevant training and need professional technical support. Theme 4: there is no system of medical support, and an effective model needs to be established.Conclusion:There are few primary medical and health services for home patients with senile dementia, and there are regional differences. It is necessary to increase the understanding of home patients with senile dementia by various means and increase the primary medical services for home patients.

We should learn the development experience of dental hygienist in advanced countries and build the dental hygienist system suitable for our country.

Objective To study the range of central venous pressure (CVP) in very low birth weight (VLBW) infants within the first week after birth.Method From February 2014 to February 2018,50 VLBW infants without serious diseases during the first 7 days of life received umbilical venous catheters were prospectively enrolled.CVPs were measured every 4～6 h.The trend of CVP and the correlation of CVP (within 24 h) and birth weight,gestational age were analyzed.Result A total of 50 VLBW infants and 1 291 CVP measurements were included.The CVP increased slightly within 48 h after birth,and then declined.The 95％CI of CVPs were 3.67～4.21,4.03～4.49,3.90～4.33,3.67～4.19,3.29～3.97,3.14～3.94 and 2.64～ 3.55 cmH2O from day 1 to day 7.No significant correlation existed between CVP in the first day and birth weight,nor gestational age (r=-0.267,P=0.073;r=0.106,P=0.762).Conclusion The CVP of VLBW infants increased slightly within 48 h after birth,and then declined.There was no significant correlation between CVP in the first day and birth weight,nor CVP and gestational age.

BACKGROUND: Accurate serum total thyroxine (TT4) measurement is important for thyroid disorder diagnosis and management. We compared the performance of six automated immunoassays with that of isotope-diluted liquid chromatography-tandem mass spectrometry (ID-LC-MS/MS) as the reference method. We also evaluated the correlation of thyroid stimulating hormone (TSH) with TT4 measured by ID-LC-MS/MS and immunoassays. METHODS: Serum was collected from 156 patients between October 2015 and January 2016. TT4 was measured by immunoassays from Abbott (Architect), Siemens (ADVIA Centaur XP), Roche (E601), Beckman-Coulter (Dxi800), Autobio (Autolumo A2000), and Mindray (CL-1000i), and by ID-LC-MS/MS. Results were analyzed using Passing-Bablok regression and Bland-Altman plots. Minimum requirements based on biological variation were as follows: a mean bias of ≤4.5% and total imprecision (CV) of ≤3.7%. RESULTS: All immunoassays showed a correlation >0.945 with ID-LC-MS/MS; however, the slope of the Passing-Bablok regression line varied from 0.886 (Mindray) to 1.23 (Siemens) and the intercept from −12.8 (Siemens) to 4.61 (Mindray). Only Autobio, Beckman-Coulter, and Roche included the value of one in the 95% confidence interval for slope. The mean bias ranged from −10.8% (Abbott) to 9.0% (Siemens), with the lowest value noted for Roche (3.5%) and the highest for Abbott (−10.8%). Only Abbott and Roche showed within-run and total CV ≤3.7%. CONCLUSIONS: Though all immunoassays correlated strongly with ID-LC-MS/MS, most did not meet the minimum clinical requirement. Laboratories and immunoassay manufacturers must be aware of these limitations.
