ABSTRACT
Objectives@#In spite of the importance of green space for reducing obesity-related problems, there has been little exploration of whether access to green space (e.g., parks and recreational facilities) influences the obesity rate of adults in the United States. The purpose of the study was to investigate the relationships among accessibility of green space, obesity rates, and socioeconomic and demographic variables among adults living in the State of Indiana, United States. @*Methods@#We conducted a secondary data analysis to investigate the relationships among accessibility to green space, obesity rates, and socio-demographic variables with employing Geographic Information System in order to measure the accessibility of green space. @*Results@#This study found that accessibility of green space served as a strong predictor of reduced obesity rates among adults (β=-2.478; p<0.10). In addition, adults with higher education levels, as well as better access to green space, were found to have even lower obesity rates (β=-0.188; p<0.05). Other control variables such as unemployment rates, food security, and physical inactivity are additional factors that influence obesity rates among adults. @*Conclusions@#Accessibility of green space may play an important role in facilitating physical activity participation and reducing obesity rates.

ABSTRACT
Background@#The aim of this study was to describe the clinical and microbiological characteristics of infective arthritis and to analyze risk factors for Gram-negative bacterial infections that cause infective arthritis. @*Materials and Methods@#Patients admitted between 2009 - 2018 with infective arthritis in a single-tertiary hospital were evaluated retrospectively. @*Results@#A total of 181 patients were enrolled in this study. Of them, 135 were native joint infection patients and 46 were prosthetic joint infection patients. The most common site of infective arthritis was the knee (63.6%), followed by the shoulder (17.7%), and the hip (9.9%).The most frequently identified microorganisms were Staphylococcus aureus (51.1%), followed by Streptococci sp. (21.1%), Enterobacteriaceae (8.4%), and coagulase-negative-Staphylococci (CNS;8.4%). Infections due to Gram-negative bacteria and fungi made up 13.7% and 3.2% of all cases, respectively. Additionally, 20% and 4.2% of the cases involved methicillin-resistant S. aureus (MRSA) and MRCNS. We found that bacteriuria, infective arthritis in the hip, and steroid use at admission are independent risk factors for Gram-negative bacterial infections. @*Conclusion@#Infective arthritis with methicillin-resistant microorganisms reached up to about 25% in a single-tertiary hospital in Korea. In case of suspected urinary tract infection, infective arthritis of the hip joint, or steroid use at admission time among infective arthritis patients, empirical treatment covering Gram-negative microorganisms can be considered.

ABSTRACT
Sarcomatoid carcinomas of the lung are rare malignant biphasic tumors, which contain both a malignant epithelial component and a sarcomatoid component. The majority of patients are men and the mean age of onset is 60 years at the time of diagnosis. A metastasis to the regional lymph nodes and to distant organs is common. The clinical course of patients with this neoplasm is aggressive, with an overall 5-year survival rate approximating 20%. A sarcomatoid carcinoma of the lung is often observed in the large bronchi and peripheral lung field than in the trachea, and the clinical manifestations are related to their specific location. We report a case of sarcomatoid carcinoma of the lung in a 79-year-old man who presented with dyspnea on exertion.
