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.

Example Input: In patients undergoing total knee replacement (TKR), most blood loss occurs post-operatively, and the return of unwashed filtered shed blood (USB) from post-operative drainage may represent an alternative to allogeneic blood transfusion (ABT). We evaluated the impact of USB return on the cellular immune response (CIR) after TKR.', 'Forty TKR patients, intended to receive post-operative USB, entered the study. Blood samples were obtained before and 6 h, 24 h, 72 h and 7 days after surgery, and from USB, after it had been passed through a 40-microm filter. Full blood cell counts, lymphocyte subsets and immunoglobulins (IgA, IgG, IgM) were measured in all samples. A set of clinical data was collected from each patient.', 'Twenty-four of the 25 patients received a mean of 1.2 USB units and did not need additional ABT (USB group). Twelve of the 15 remaining patients who received neither USB nor ABT served as a control group for the post-operative CIR study. All patients showed a post-operative decrease in T-cell and natural killer (NK) cell counts, but not B-cell counts, and there were no significant differences between the groups with regard to CIR parameters, post-operative infection or hospital stay.

Example Input: Chronic stress is generally known to exacerbate the development of numerous neuropsychiatric diseases such as fear and anxiety disorders, which is at least partially due to the disinhibition of amygdala subsequent to the prolonged stress exposure. GABA receptor A (GABAAR) mediates the primary component of inhibition in brain and its activation produces two forms of inhibition: the phasic and tonic inhibition. While both of them are critically engaged in limiting the activity of amygdala, their roles in the amygdala disinhibition subsequent to chronic stress exposure are largely unknown.', 'We investigated the possible alterations of phasic and tonic GABAAR currents and their roles in the amygdala disinhibition subsequent to chronic stress. We found that both chronic immobilization and unpredictable stress led to long lasting loss of tonic GABAAR currents in the projection neurons of lateral amygdala. By contrast, the phasic GABAAR currents, as measured by the spontaneous inhibitory postsynaptic currents, were virtually unaltered. The loss of tonic inhibition varied with the duration of daily stress and the total days of stress exposure. It was prevented by pretreatment with metyrapone to block corticosterone synthesis or RU 38486, a glucocorticoid receptor antagonist, suggesting the critical involvement of glucocorticoid receptor activation. Moreover, chronic treatment with corticosterone mimicked the effect of chronic stress and reduced the tonic inhibition in lateral amygdala of control mice. The loss of tonic inhibition resulted in the impaired GABAergic gating on neuronal excitability in amygdala, which was prevented by metyrapone pretreatment.

Example Input: We assessed the clinical effectiveness of postoperative enteral stimulation by gut feeding in patients with severe acute pancreatitis (SAP).', 'Medical records of 63 patients who were operated on within the past 4 y due to deterioration of SAP were included in this retrospective study. Patients were stratified in gut feeding (GF; n = 33) and standard therapy (ST; n = 30) groups according to the postoperative therapy provided. The GF group received postoperative standard therapy and enteral stimulation by gut feeding, and the ST group received standard therapy only. The Acute Physiology and Chronic Health Evaluation II score, incidence of the systemic inflammatory response syndrome (SIRS), multiple organ dysfunction syndrome (MODS), daily calories supply, complication rate, and outcomes were analyzed.', 'Patient characteristics did not differ between groups when considering age and severity of the disease. All patients underwent similar surgical interventions. SIRS and MODS were observed initially with the same frequency in both groups. Regression of MODS and a lower postoperative complication rate was observed more often in the GF group. Development of early pulmonary complications was observed in 12.1% to 13.3% in both groups, irrespective of the time of surgery. Subsequently, pulmonary complications developed in 15.2% of GF patients compared with 43.3% of ST patients (P <0.05). Acute renal insufficiency developed similarly in 33.3% of the GF patients and in 26.7% of the ST patients within 3 d after admission. Acute renal insufficiency developed later on only in the ST group (26.7%, P <0.05). Wound- and catheter-related septic complications were considerably more frequent in the ST group (30.0%) than in the GF group (9.1%, P <0.05). Intensive care and hospital stays did not differ. Postoperative gut feeding was associated with 6.1% mortality in the GF compared with 26.7% in the ST (P <0.05).
