TASK DEFINITION: Given a passage classify if the passage has a definite objective/aim/goal or not. Output '1' if the passage has a defininte objective/aim/goal and output '0' if the passage does not have a definite objective/aim/goal.
PROBLEM: Information about malaria risk factors at high altitudes is scanty. Understanding the risk factors that determine the risk of malaria transmission at high altitude villages is important to facilitate implementing sustainable malaria control and prevention programs.', 'An unmatched case control study was conducted among patients seeking treatment at health centers in high altitude areas. Either microscopy or rapid diagnostic tests were used to confirm the presence of plasmodium species. A generalized linear model was used to identify the predictors of malaria transmission in high altitude villages.', 'Males (AOR\u200a=\u200a3.11, 95%CI: 2.28, 4.23), and those who traveled away from the home in the previous month (AOR\u200a=\u200a2.01, 95% CI: 1.56, 2.58) were strongly associated with presence of malaria in high altitude villages. Other significant factors, including agriculture in occupation (AOR\u200a=\u200a1.41, 95% CI: 1.05, 1.93), plants used for fencing (AOR\u200a=\u200a1.70, 95% CI: 1.18, 2.52) and forests near the house (AOR\u200a=\u200a1.60, 95% CI: 1.15, 2.47), were found predictors for malaria in high altitude villages.

PROBLEM: To study the presence of citrullinated proteins in inflammatory conditions and in clinically non-affected tissues of controls.', 'Synovial biopsy specimens from 19 patients with rheumatoid arthritis and 10 healthy controls were investigated by immunohistochemistry. Additionally, muscle tissue from 5 patients with polymyositis and from 7 healthy controls, intestinal tissue from macroscopically affected and non-affected areas from 10 patients with inflammatory bowel disease (IBD) and tonsil tissues from 4 chronically inflamed tonsils were studied.', 'Citrullinated proteins were present in all synovial biopsy specimens from patients with rheumatoid arthritis, whereas only three of 10 healthy synovial biopsy specimens showed scarce amounts of citrullination. Citrullination was also present in all myositis-affected muscles, whereas it was absent in the muscle tissues of controls. All tonsil biopsy specimens studied were positive for citrulline. Even though more frequently detected in the macroscopically affected colonic areas, no marked difference was observed in the pattern or extent of citrullination between the macroscopically affected and non-affected intestinal IBD tissues.

PROBLEM: Immunosuppression after burn injury increases the risk of sepsis and multiple organ failure. We examined changes of immune function in mice after burn injury and investigated the immunostimulatory effect of oligodeoxynucleotides containing CpG motifs.', 'Male BALB/c mice (8-10 wk old) received a full-thickness burn to 20% of their body surface area, after which the immunological parameters of splenic macrophages were evaluated. To assess the immunostimulatory effect of oligodeoxynucleotide treatment, splenic macrophages harvested from burned mice were incubated with oligodeoxynucleotides. Then cytokine production and major histocompatibility complex class II antigen expression were measured. To assess the in vivo effect of oligodeoxynucleotides, intraperitoneal administration was done on day 4 after burn injury, and class II antigen expression by splenic macrophages was measured 10 d later.', 'Class II antigen expression and the synthesis of cytokines (interleukin-12, tumor necrosis factor-alpha, interleukin-6, and interleukin-1) by splenic macrophages were significantly reduced after burn injury, while incubation of splenic macrophages from burned mice with oligodeoxynucleotides partially enhanced the production of interleukin-12, tumor necrosis factor-alpha, interleukin-6, and interleukin-1. In addition, intraperitoneal administration of oligodeoxynucleotides enhanced class II antigen expression by splenic macrophages.
