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.

Lymphocyte alterations have been associated with an increased prevalence of acute respiratory infections in COPD patients. AM3 is an oral immunomodulator that normalizes the defective functions of peripheral blood natural killer and phagocytic cells in COPD patients and improves their health-related quality of life.', 'To characterize putative systemic abnormalities of the T-cell compartment in COPD patients, and to investigate whether AM3 can restore such abnormalities.', 'The study was a randomized, prospective, double-blind, placebo-controlled trial in a cohort of COPD patients. The results were also compared to those of nonsmoker and ex-smoker healthy control subjects.', 'Outpatient departments of four hospitals.', 'Seventy COPD patients were randomized to receive either AM3 or a placebo orally for 90 consecutive days. Populations of 36 healthy nonsmokers and 36 healthy ex-smokers were used as control subjects.', 'Peripheral blood mononuclear cell (PBMC) proliferation and production of interleukin (IL)-2, IL-4, IL-12p40, tumor necrosis factor-alpha, and interferon (IFN)-gamma proteins in response to the T-cell polyclonal mitogens were assessed at baseline and at the end of treatment.', 'The proliferative response was significantly decreased in COPD patients. Decreased production of IFN-gamma was the only defect in the profiles of the cytokine measures, and was selectively observed in COPD patients, but not in nonsmoker and ex-smoker healthy control subjects. Treatment with AM3 significantly restored the PBMC proliferative response to polyclonal mitogens and significantly promoted stimulated IFN-gamma production in these patients. The normalization of these proliferative responses was not related to significant variations in the numbers of peripheral blood monocytes, CD3+, CD4+, CD8+ cells or of any major naïve/memory/activated T-cell subset. The increased IFN-gamma production in the AM3 study arm was associated with an increase in the mean of number of IFN-gamma molecules produced per CD8+ T cells.

To evaluate manual lymphatic drainage (MLD) and active exercise effects on lymphatic alterations of the upper limb (UL), range of motion (ROM) of shoulder, and scar complications after breast cancer surgery.', 'Clinical trial.', 'Health care center.', 'Women (N=105) undergoing radical breast cancer surgery who were matched for staging, age, and body mass index.', 'Women (n=52) were submitted to MLD and 53 to active exercises for UL for 1 month and followed up.', 'Shoulder ROM, surgical wound inspection and palpation, UL circumference measurements, and lymphoscintigraphy were performed in preoperative and postoperative periods.', 'There was no significant difference between groups with regard to wound healing complications, ROM, and UL circumferences. After surgery, 25 (48.1%) of the MLD group and 19 (35.8%) of the active exercise group showed worsening in radiopharmaceutical uptake velocity, whereas 9 (17.3%) of the MLD group and 11 (20.8%) of the active exercise group showed improved velocity (P=.445). With regard to uptake intensity, 27 (51.9%) of the MLD group and 21 (39.6%) of the active exercise group showed worsening whereas 7 (13.5%) of the MLD group and 7 (13.2%) of the active exercise group showed some improvement (P=.391). The presence of collateral circulation was similar in both groups at both time points evaluated. The active exercise group had a significant increase in postoperative liver absorption (P=.005), and the MLD group had a significant increase in postoperative dermal backflow (P=.024).

Obesity and hemorrhagic shock following trauma are predictors of mortality but have conflicting effects on coagulation. Following hemorrhage, tissue injury and hypoperfusion lead to acute traumatic coagulopathy (ATC), producing a hypocoagulable state. Inversely, obesity promotes clotting and impairs fibrinolysis to yield a hypercoagulable state. High rates of venous thromboembolism, organ failure, and early mortality may be caused by hypercoagulability in obese patients. We hypothesize that obesity prevents the development of ATC following injury-induced hemorrhagic shock.', 'Male Sprague-Dawley rats (250-275 g) were fed a high-fat diet (32%kcal from fat) for 4 weeks to 6 weeks and diverged into obesity-resistant (OR, n = 9) and obesity-prone (OP, n = 9) groups. Age-matched control (CON) rats were fed normal diet (10% kcal from fat, n = 9). Anesthetized rats were subjected to an uncontrolled hemorrhage by a Grade V splenic injury to a mean arterial pressure (MAP) of 40 mm Hg. Hypotension (MAP, 30-40 mm Hg) was maintained for 30 minutes to induce shock. MAP, heart rate, lactate, base excess, cytokines, blood loss, and thrombelastography (TEG) parameters were measured before and after hemorrhagic shock.', 'At baseline, OP rats exhibited a shorter time to 20-mm clot (K), and higher rate of clot formation (α angle), clot strength (maximal amplitude), and coagulation index, compared with the CON rats (p < 0.05), indicating enhanced coagulation. Physiologic parameters following shock were similar between groups. In the CON and OR rats, shock prolonged the time to clot initiation (R) and K and decreased α angle and coagulation index (all p < 0.05 vs. baseline). In contrast, shock had no effect on these TEG parameters in the OP rats. Maximal amplitude was the only TEG parameter affected by shock in the OP rats, which was decreased in all groups.
