Objective: To investigate the hot spots and epidemiologic characteristics of hand, foot and mouth disease (HFMD) in Jinan municipality from 2009 to 2016. Methods: Disease reports of HFMD in Jinan from 2009-2016 were collected and analyzed with ArcGis 10.2 to show the hot spot in different villages and towns, as well as clustering analysis and descriptive epidemiology to show epidemiologic characteristics. Results: A total of 89 486 HFMD cases were reported and the reported annual incidence rate was 160.94/100000 during the 7-year period, which increased year by year, and within the whole city, each county was at a higher epidemic level; the curve of incidence is unimodal and the incidence peak occurred mostly between May and August, especially in June; 115 severe cases were reported and the ratio was 0.13%. Of the reported cases, 81.51% were between 1 to 4 years old; 60.36 % were children living scattered. The hot spots were like a circle surrounding the core areas, showing a tendency of increase; the proportion of EV71, CVA16 and other enteroviruses were 33.67%、37.22%and 29.09%, respectively, and they appeared in turn, but severe cases were mostly affected by EV71. Conclusions The HFMD in Jinan is in a highly prevalent level, with low ratio of severe cases. Seasonal(high in summer) and unimodal; more common among children between 1 to 4 years old, living scatted and in urban and rural linking areas, with the tendency of increasing of hot spots; prevalent pathogens appear in turn.

OBJECTIVETo investigate the effect of weather patterns on the incidence of hand foot and mouth disease (HFMD) in Jinan.

METHODSHFMD confirmed cases aged ≤5 years old for the period of 2012-2014 were collected from National Notifiable Disease Report System (NNDRS). Simultaneous meteorological data, including daily average temperature, relative humidity, atmospheric pressure, wind velocity, rainfall and duration of sunshine were obtained from the website of Jinan meteorological bureau. A negative binomial multivariable regression was used to identify the relationship between meteorological variables and HFMD.

RESULTSDuring the study period, a total of 40 405 HFMD cases aged ≤5 years old were reported. The incident peak occurred from May to July, a total of 22 254 cases were reported during this period, which accounted for 55.08% of whole cases. After adjusting by "year", each 1 °C rise of weekly average temperature corresponded to an increase of 6.70% (95%CI:6.35% to 7.06%) in the weekly number of HFMD cases, while a 1 kPa rise of weekly average atmospheric pressure corresponded to a decrease in the number of cases by 44.77% (95%CI: -46.23% to -41.91%). Likewise, a one percent rise in weekly average relative humidity corresponded to an increase of 1.96% (95%CI: 1.84% to 2.09%), a 1 m/h rise in weekly average wind velocity corresponded to an increase of 16.63% (95% CI:14.08% to 19.25%), a hour add in weekly duration of sunshine corresponded to a decrease of 0.82% (95% CI : -0.93% to -0.72%), in the weekly number of HFMD cases.

CONCLUSIONWeather factors including temperature, atmospheric pressure, relative humidity, wind velocity, and duration of sunshine had a significant influence on occurrence and transmission of HFMD in Jinan city.

Objective: To investigate the current trends of breast reconstruction(BR) after mastectomy in China. Methods: A list of hospitals with more than 200 cases of breast cancer surgery per year nationwide was obtained, and 110 institutions were selected according to the geographical distribution. The research was conducted in the form of a questionnaire survey, and 92.3% (169/183) of the questions were single-choice questions. Information such as demographics of surgeons and hospitals, number of mastectomy and BR, type and timing of BR was included in the survey. Survey formal notification letter was issued by the China Anti-Cancer Association Breast Cancer Committee and Chinese College of Surgeons, Committee of Mammary Surgeons. Questionnaires were sent to the respondents of each center by email. The survey time range was from January 1, 2017 to December 31, 2017. All data were completely collected before September 7, 2018. Results: A total of 110 units participated in the survey. In total, 87.3% (96/110) of the hospitals have conducted BR surgery. The BR after mastectomy was 10.7% (6 534/61 099), among this, implant BR accounted for 65.7%(4 296/6 534), autologous BR accounted for 20.1% (1 312/6 534), and autologous combined implant BR accounted for 14.2% (927/6 534). Immediate reconstruction accounted for 67.6% (4 417/6 534) of BR, while delayed BR accounted for 32.4% (2 097/6 534). In 2017, 77.8% (35/45) of the plastic surgery departments cooperated with general surgery departments. General BR could be conducted after mastectomy accounted for 83.6% (92/110). The proportion of reconstruction was positively correlated with the gross domestic product (GDP) per capita (r=0.311, P=0.002). The one-step implant-based BR(IBBR) was the most preferred type in immediate BR. Two-step IBBR was the most preferred method in delayed BR. Hospitals that routinely evaluated aesthetics after BR accounted for 64.6% (62/96), while only 16.7% (16/96) of hospitals used patient-reported outcome measure (PROM). The most commonly used PROM tool was BREAST-Q. Conclusions The overall BR in China is on upward trend, but gap between China and the developed countries still exists. Breast surgery departments should strengthen further cooperation with plastic surgery departments. Simultaneously, the aesthetics evaluation and PROM after BR should be put a high premium.

Objective:To determine national trends for breast conserving surgery and to explore the factors affecting the scale of breast conserving surgery in China.Methods:A questionnaire survey was mailed to 110 hospitals with an year′s volume of more than 200 breast cancer surgeries in each center in China concerning hospital variations and percentage of breast conserving surgery.Results:The overall proportion of breast conserving surgery is 21.9% for operable breast cancer in China. There is a significant positive correlation between local Gross Domestic Product (GDP) and the rate of breast conserving surgery ( P=0.001). Hospitals with higher annual operation volume have higher breast-conserving ratios( P=0.042). Compared with non-teaching hospitals, more patients with stage I breast cancer underwent breast conserving surgery in teaching hospitals ( P=0.021). After breast-conserving surgery, the proportion of positive margins needing reoperation had a lower percentage and in cancer hospitals it was the lowest ( P=0.023). The method of pathological evaluation and the remedy strategy for positive margin was not related to per capita GDP and hospital category ( P>0.05). Conclusions:This survey demonstrates the current practices of breast conserving surgery in China. Local GDP, hospital category and tumor stage were factors influencing breast conserving surgery. Breast conserving surgery in China is still at a low level compared with developed countries.
