BACKGROUND: Age-related macular degeneration (AMD) is a major cause of irreversible blindness, and awareness of this disease is important in the prevention of blindness. However, lack of public awareness of AMD was shown in previous studies, and there was no report of AMD awareness in the Mainland of China. Therefore, the aim of our study was to assess the awareness of AMD and its risk factors among Beijing residents in China. METHODS: A cross-sectional, computer-assisted, telephone investigation was conducted to measure the awareness of AMD among Beijing residents...

REVIEW
David Q Rich
To address limitations of observational epidemiology studies of air pollution and health effects, including residual confounding by temporal and spatial factors, several studies have taken advantage of 'natural experiments', where an environmental policy or air quality intervention has resulted in reductions in ambient air pollution concentrations. Researchers have examined whether the population impacted by these air quality improvements, also experienced improvements in various health indices (e.g. reduced morbidity/mortality)...

Effects of MC4R variants in previous Chinese population studies were inconsistent. Gene-environment interactions might influence the effect of MC4R variants on obesity, which was still unclear. We performed the study to clarify the association of variants near MC4R gene with obesity-related phenotypes and gene-environment interactions in Chinese children and adolescents. Two common variants (rs12970134 and rs17782313) near MC4R were genotyped in 2179 children and adolescents aged 7-18 years in Beijing of China...

OBJECTIVES: Childhood obesity is rising rapidly in China, especially in urban areas. Knowledge about how school environment and policies (SEP) may have contributed to the epidemic remains limited. We examined SEP and their associations with students' eating behaviors and overweight/obesity in urban China. METHODS: Data were collected from 1648 students (plus their parents and schools) in 16 primary and middle schools (4 schools/per city) in four mega-cities across China: Beijing, Shanghai, Nanjing, and Xi'an...

BACKGROUND: Procedural sedation for painful procedures in the emergency department (ED) can be accomplished with various pharmacological agents. The choice of the sedative used is highly dependent on procedure- and patient characteristics and on personal- or local preferences. METHODS: We conducted a multicenter retrospective cohort study of procedural sedations performed in the EDs of 5 hospitals in the Netherlands over a 4year period to evaluate the efficacy- (success rate of the intended procedure) and safety (incidence of sedation (adverse) events) of propofol sedations compared to midazolam sedations...

Reducing low-density lipoprotein cholesterol (LDL-C) to target ≤1.81 mmol/L is a common therapeutic goal after acute coronary syndrome (ACS). This study aimed to examine the factors associated with reaching or not this LDL-C target after 1 year of optimal statin therapy postpercutaneous coronary intervention (PCI). This was a retrospective study of 633 consecutive prospectively enrolled patients with ACS treated between January 2011 and December 2012 at the Beijing Hospital (China). All patients were treated with PCI and statins for 1 year...

Talaromyces contains both asexual and sexually reproducing species. This genus is divided in seven sections and currently has 105 accepted species. In this study we investigated the Talaromyces isolates that were obtained during a study of indoor air collected in Beijing, China. These indoor Talaromyces strains are resolved in four sections, seven of them are identified as T. islandicus, T. aurantiacus, T. siamensis and T. albobiverticillius according to BenA sequences, while 14 isolates have divergent sequences and are described here as nine new species...

BACKGROUND: Brief cognitive-behavioural therapy (CBT) is an emerging treatment for schizophrenia in community settings; however, further trials are needed, especially in non-Western countries. AIMS: To test the effects of brief CBT for Chinese patients with schizophrenia in the community (trial registration: ChiCTR-TRC-13003709). METHOD: A total of 220 patients with schizophrenia from four districts of Beijing were randomly assigned to either brief CBT plus treatment as usual (TAU) or TAU alone...

Atmospheric particle is one of the risk factors for respiratory disease; however, their injury mechanisms are poorly understood, and prevention methods are highly desirable. We constructed artificial PM2.5 (aPM2.5) particles according to the size and composition of actual PM2.5 collected in Beijing. Using these artificial particles, we created an inhalation-injury animal model. These aPM2.5 particles simulate the physical and chemical characteristics of the actual PM2.5, and inhalation of the aPM2.5 in rat results in a time-dependent change in lung suggesting a declined lung function, injury from oxidative stress and inflammation in lung...

BACKGROUND: Quasi-moyamoya disease (MMD) is characterized by moyamoya vasculopathy and well recognized comorbidity. Whether the recently identified MMD susceptibility gene variant, p.R4810K (rs112735431), is associated with quasi-MMD remains unclear. METHODS: This study was a 2-hospital-based case-control study that was conducted in the neurosurgical departments of Beijing Tiantan Hospital and Peking University International Hospital. A total of 42 patients and 161 controls were enrolled...

BACKGROUND: The American Heart Association's 2020 Strategic Goals have defined a new concept of cardiovascular health for adults and children, emphasizing the importance of primordial prevention of cardiovascular diseases. However, detailed data on the trends of ideal cardiovascular health in Chinese children and adolescents are sparse. METHODS: A total of 5596 children and adolescents (aged 6-18years) were selected from two cross-sectional surveys conducted in 2004 and 2014, respectively...

The advent of whole-genome sequencing has provided an unprecedented detail about the evolution and genetic significance of species-specific variations across the whole Mycobacterium tuberculosis Complex. However, little attention has been focused on understanding the functional roles of these variations in the protein coding sequences. In this work, we compare the coding sequences from 74 sequenced mycobacterial species including M. africanum, M. bovis, M. canettii, M. caprae, M. orygis, and M. tuberculosis Results show that albeit protein variations affect all functional classes, those proteins involved in lipid and intermediary metabolism and respiration have accumulated mutations during evolution...

BACKGROUND: A principal reason for flap compromise in oral and maxillofacial head and neck surgery, and failure of a free flap transfer, is thrombosis of a drainage vein such as the internal jugular vein. This study characterized flap compromise caused by internal jugular vein thrombosis after a free flap transfer, and its management. PATIENTS AND METHODS: A retrospective clinical study was conducted of 306 consecutive microvascular free flaps performed for 305 patients with head and neck cancer from March 2003 to March 2013 at the Department of Oral and Maxillofacial Surgery at Beijing Stomatological Hospital, Capital Medical University...

BACKGROUND: The incidence of young coronary heart disease (CHD, ≤45 years) in China is increasing. Secondary prevention to counter this trend is an important contemporary public health issure. METHODS: A total of 5288 patients (≤45 years) diagnosed with CHD and hospitalized at the Chinese PLA General Hospital and Anzhen Hospital, both in Beijing, were enrolled after satisfying the inclusion criteria. RESULTS: Young CHD patients increased in number from 2010 to 2014, especially men...

BACKGROUND: Risk adjustment is essential for valid comparison of patients' health outcomes or performances of health care providers. Several risk adjustment methods for liver diseases are commonly used but the optimal approach is unknown. This study aimed to compare the common risk adjustment methods for predicting in-hospital mortality in cirrhosis patients using electronic medical record (EMR) data.
