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.

The aim of this study was to evaluate the characteristics of low-energy femoral insufficiency fractures in elderly patients.', 'The study retrospectively evaluated the clinical course of 4 patients with low-energy femoral shaft and subtrochanteric fractures admitted to our department between 2009 and 2011. Three patients had prior long-term alendronate therapy and one had prior glucocorticoid therapy.', 'There were 5 femoral shaft fractures, 2 incomplete shaft fractures, 2 subtrochanteric and 1 intertrochanteric fractures. All femoral shaft fractures had characteristic fracture patterns with thickened lateral cortices at the proximal fragment. Six femurs had excessive medial femoral bowing, which complicated intramedullary nailing. Additional fractures were seen on both femurs of one patient who had been primarily treated with short implants. A bifocal femoral fracture was seen in one femur. Union was achieved in all patients. Two patients were able to walk independently, one with a cane and one with double crutches.

Prostate cancer is the second most common form of cancer in males, affecting one in eight men by the time they reach the age of 70 years. Current diagnostic tests for prostate cancer have significant problems with both false negatives and false positives, necessitating the search for new molecular markers. A recent investigation of endosomal and lysosomal proteins revealed that the critical process of endosomal biogenesis might be altered in prostate cancer. Here, a panel of endosomal markers was evaluated in prostate cancer and nonmalignant cells and a significant increase in gene and protein expression was found for early, but not late endosomal proteins. There was also a differential distribution of early endosomes, and altered endosomal traffic and signaling of the transferrin receptors (TFRC and TFR2) in prostate cancer cells. These findings support the concept that endosome biogenesis and function are altered in prostate cancer. Microarray analysis of a clinical cohort confirmed the altered endosomal gene expression observed in cultured prostate cancer cells. Furthermore, in prostate cancer patient tissue specimens, the early endosomal marker and adaptor protein APPL1 showed consistently altered basement membrane histology in the vicinity of tumors and concentrated staining within tumor masses. These novel observations on altered early endosome biogenesis provide a new avenue for prostate cancer biomarker investigation and suggest new methods for the early diagnosis and accurate prognosis of prostate cancer.

Non-response to cardiac resynchronization therapy (CRT) might be due to insufficient resynchronization as a result of a sub-optimal left ventricular lead positon (LV-LP).', 'To evaluate the impact of different LV-LPs on mortality and symptomatic improvement in a large cohort of patients treated with CRT.', "We performed a nationwide cohort study on consecutive patients receiving a CRT device from 1997 to 2012 registered in the Danish pacemaker and ICD register. The LV-LP was defined clockwise in a left anterior oblique (LAO) view and categorized as anterior (≤2 o'clock), lateral (2 to 4 o'clock) or posterior (>4 o'clock), and as basal, mid-ventricular, or apical in a right anterior oblique (RAO) view. Outcomes were all cause mortality and clinical response (improvement in NYHA class). Adjusted hazard ratio (aHR) and odds ratio (aOR) with 95% confidence intervals (CI) were calculated using Cox and logistic regression analysis.", 'A total of 2594 patients were included. A lateral LV-LP, (aHR 0.77, 95% CI 0.64-0.92, p=0.004), and a posterior LV-LP, (aHR 0.71 95% CI 0.53-0.97, p=0.029) were associated with lower mortality as compared to an anterior LV-LP. A lateral LV-PV was associated with higher clinical response rate as compared to an anterior LV-LP (aOR 1.37, 1.03-1.83, p=0.032). No statistically significant associations were observed between LV-LP in the RAO view and mortality or clinical response.
