Purpose: Previous research on incremental hemodialysis transition has mainly focused on one or two benefits or prognoses. We aimed to conduct a comprehensive analysis by investigating whether incremental hemodialysis was simultaneously associated with adequate dialysis therapy, stable complication indicators, long-lasting arteriovenous vascular access, and long-lasting preservation of residual kidney function (RKF) without increasing mortality or hospitalization.Patients and Methods: Incident hemodialysis patients from Huashan Hospital in Shanghai, China, over the period of 2012 to 2019, were enrolled and followed every three months until death or the time of censoring. Changes in complication indicators from baseline to all post-baseline visits were analyzed by mixed-effects models. The outcomes of RKF loss, arteriovenous vascular access complications, and the composite of all-cause mortality and cardiovascular events were compared between incremental and conventional hemodialysis by Cox proportional hazards model.Results: Of the 113 patients enrolled in the study, 45 underwent incremental and 68 conventional hemodialysis. There were no significant differences in the changes from baseline to post-baseline visits in complication indicators between the two groups. Incremental hemodialysis reduced the risks of RKF loss (HR, 0.33; 95% CI, 0.14-0.82), de novo arteriovenous access complication (HR, 0.26; 95% CI, 0.08-0.82), and recurrent arteriovenous access complications under the Andersen-Gill (AG) model (HR, 0.27; 95% CI, 0.10-0.74) and the Prentice, Williams and Peterson Total Time (PWP-TT) model (HR, 0.31; 95% CI, 0.12-0.80). There were no significant differences in all-cause hospitalization or the composite outcome between groups.Conclusion: Incremental hemodialysis is an effective dialysis transition strategy that preserves RKF and arteriovenous access without affecting dialysis adequacy, patient stability, hospitalization risk and mortality risk. Randomized controlled trials are warranted. [ABSTRACT FROM AUTHOR]

Background: Accumulating evidence has revealed that dental anxiety (DA) is associated with pain and patient satisfaction related to dental procedures. However, relevant reports are limited and inconsistent in oral implant patients. Purpose: The purpose of this study was to investigate the prevalence of dental anxiety, pain perception, and analyze their interrelationship in Chinese patients with oral implant surgery. Materials and Methods: A cross‐sectional study was performed according to the strengthening the reporting of observational studies in epidemiology (STROBE) guideline. Consecutive patients who received oral implant surgeries during February‐March of 2018 in Shanghai Ninth People's Hospital were recruited. The modified dental anxiety scale and visual analog scale were used to evaluate the level of the patient's DA and pain perception. Multivariate logistic regression was applied to analyze the influence of DA on pain perception of patients during oral implant surgery. Results: The prevalences of moderate and high preoperative DA were 66.6% and 11.9% in Chinese patients with oral implant surgery, respectively. Seven points eight percent of patients experienced pain perception during surgery. The result of multiple logistic regression showed that there was no significant influence of moderate preoperative DA (OR = 2.0, 95%CI: 0.5‐8.2) on pain perception. However, a significant influence of high preoperative DA (OR = 6.4, 95%CI: 1.3‐30.8) was found on pain perception of patients with oral implant surgery. Significant influences of moderate perioperative DA (OR = 5.0, 95%CI: 1.1‐22.9) and high perioperative DA (OR = 8.7, 95%CI: 1.1‐69.9) were also found on pain perception of patients during oral implant surgery. Conclusions: The results of the study indicated that DA was very common in Chinese patients with oral implant surgery. DA may increase pain perception of patients during oral implant surgery.

Abstract: This paper analyzes the processes and characteristics of urbanization in Shanghai, focusing on the population and land use and land cover (LULC) change, and its correlation with the evolution of climatic and ecological indicators based on the historical land use data, meteorological station data, social statistical data, normalized difference vegetation index (NDVI) and land surface temperature (LST) data. The possible association between urban heat island (UHI) and urbanization indicators are also discussed. Examination of the population variation indicates a continuously increase of registered population and a rapid increase of floating population that mainly comes from neighboring provinces in recent years. With rapid urban sprawl, a large amount of cultivated lands has been replaced with building lands around urban areas and towns of Shanghai. Urbanization is correlated with the increase of air temperature, hot days and the decrease of relative humidity, wind speed and vegetation NDVI in Shanghai. The growth of UHI in Shanghai has been driven by the continuous increase of buildings, paved roads, buses, population and GDP, as well as the decrease of cultivated land. Boosting the area of green land in urban areas has to a certain extent mitigated the UHI in Shanghai in recent years. [Copyright &y& Elsevier]

This paper discusses the characteristics of high-impact weather events based on available data during 1960-2009, including the frequency and extreme value of rainstorm, typhoon, thunderstorm, strong wind, tornado, fog, haze and hot days in Shanghai, China. The frequency and spatial distribution of meteorological disasters and their impacts on both human and property during 1984-2009 are also discussed. Examination of the frequency indicates a decreasing trend in the occurrence of typhoon, thunderstorm, strong wind, tornado and fog, and an increasing trend in the occurrence of rainstorm, haze and hot days. The number of casualties caused by meteorological disasters appears to show a slight decreasing trend while the value of direct economic loss is increasing slightly during 1984-2009, and the number of collapsed or damaged buildings and the area of affected crops have no significant trend in Shanghai. These results can be attributed to the great efforts for prevention and mitigation of meteorological disasters made by Shanghai government in recent 60 years. With global climate change, urbanization and rapid economic development, Shanghai has become more vulnerable to high-impact weather and meteorological disaster, especially precipitation extreme, summer high temperature, haze and typhoon, so more strategies of mitigation and/or adaptation of natural disasters are quite useful and necessary for local government and the public in the future.

PURPOSE: This clinical retrospective study is aimed to offer the clinical epidemiologic information about oral and maxillofacial trauma based on 1420 cases. METHODS: From 2005-2006, 1420 oral and maxillofacial traumatic cases were treated in Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine. Data regarding age, gender, cause of injury, pattern of fracture and associated systemic injuries were reviewed. RESULTS: The male to female ratio of 1420 cases was 3.24:1;and 36.22% of patients were aged between 20 and 30 years. The most common cause of injury was road traffic accident (42.07%); the zygoma (41.83%) and mandible (29.50%) were the most frequent fracture sites; 43.6% of the cases were not treated or not treated properly in 3 weeks after trauma. CONCLUSIONS: Road traffic accident is the most common cause of hospitalized traumatic cases, and the zygoma and mandible was the susceptible sites to be fractured. Because of the high proportion of inappropriately treated cases, we should take much attention to dentofacial deformities resulting from delayed or inappropriate treatment of oral and maxillofacial trauma cases.
