Abstract
BACKGROUND Sepsis is one of the most frequent reasons for acute intensive care unit (ICU) admission of very old patients and mortality rates are high. However, the impact of pre-existing physical and cognitive function on long-term outcome of ICU patients ≥ 80 years old (very old intensive care patients (VIPs)) with sepsis is unclear. OBJECTIVE To investigate both the short- and long-term mortality of VIPs admitted with sepsis and assess the relation of mortality with pre-existing physical and cognitive function. DESIGN Prospective cohort study. SETTING 241 ICUs from 22 European countries in a six-month period between May 2018 and May 2019. SUBJECTS Acutely admitted ICU patients aged ≥80 years with sequential organ failure assessment (SOFA) score ≥ 2. METHODS Sepsis was defined according to the sepsis 3.0 criteria. Patients with sepsis as an admission diagnosis were compared with other acutely admitted patients. In addition to patients' characteristics, disease severity, information about comorbidity and polypharmacy and pre-existing physical and cognitive function were collected. RESULTS Out of 3,596 acutely admitted VIPs with SOFA score ≥ 2, a group of 532 patients with sepsis were compared to other admissions. Predictors for 6-month mortality were age (per 5 years): Hazard ratio (HR, 1.16 (95% confidence interval (CI), 1.09-1.25, P < 0.0001), SOFA (per one-point): HR, 1.16 (95% CI, 1.14-1.17, P < 0.0001) and frailty (CFS > 4): HR, 1.34 (95% CI, 1.18-1.51, P < 0.0001). CONCLUSIONS There is substantial long-term mortality in VIPs admitted with sepsis. Frailty, age and disease severity were identified as predictors of long-term mortality in VIPs admitted with sepsis.

Abstract
This paper presents a framework to address three dimensional (3-D) dynamic walking for a bipedal exoskeleton with underactuated legs. To achieve this goal, the framework is constructed via a trajectory generator and an optimized inverse kinematics algorithm that can cope with underactuation. In order to feasibly attain task velocities with underactuated legs, the inverse kinematics algorithm makes use of a task prioritization method via the exploitation of null space. In doing so, the tasks with lower priority, e.g., swing foot orientation, are attained as much as possible without disrupting the higher priority tasks, such as CoM trajectory. Meanwhile, the trajectory generator utilizes the ZMP concept analytically and ensures the acceleration continuity throughout the whole walking period, regardless of the contact and phase changes. The proposed method is verified via a lumped human-bipedal exoskeleton model that is developed and simulated in MSC.ADAMS simulation environment. As a result, we obtained feasible and dynamically balanced 3-D walking motion, in which no oblique foot landing or exaggerated torso orientation variations were observed, despite the underactuated nature of the robot legs.

Abstract
Coagulation is recognized as a key player in inflammatory and autoimmune diseases. The aim of the current research was to examine the effect of pretreatment with acenocoumarol on the development of acute pancreatitis (AP) evoked by cerulein. Methods: AP was induced in rats by cerulein administered intraperitoneally. Acenocoumarol (50, 100 or 150 µg/kg/dose/day) or saline were given once daily for seven days before AP induction. Results: In rats with AP, pretreatment with acenocoumarol administered at the dose of 50 or 100 µg/kg/dose/day improved pancreatic histology, reducing the degree of edema and inflammatory infiltration, and vacuolization of acinar cells. Moreover, pretreatment with acenocoumarol given at the dose of 50 or 100 µg/kg/dose/day reduced the AP-evoked increase in pancreatic weight, serum activity of amylase and lipase, and serum concentration of pro-inflammatory interleukin-1β, as well as ameliorated pancreatic DNA synthesis and pancreatic blood flow. In contrast, acenocoumarol given at the dose of 150 μg/kg/dose did not exhibit any protective effect against cerulein-induced pancreatitis. Conclusion: Low doses of acenocoumarol, given before induction of AP by cerulein, inhibit the development of that inflammation.

Abstract
Coagulative disorders are known to occur in acute pancreatitis and are related to the severity of this disease. Various experimental and clinical studies have shown protective and therapeutic effect of heparin in acute pancreatitis. Aim of the present study was to determine the influence of acenocoumarol, a vitamin K antagonist, on the development of acute pancreatitis. Studies were performed on male Wistar rats weighing 250 - 270 g. Acenocoumarol at the dose of 50, 100 or 150 μg/kg/dose or vehicle were administered once a day for 7 days before induction of acute pancreatitis. Acute pancreatitis was induced in rats by pancreatic ischemia followed by reperfusion. The severity of acute pancreatitis was assessed after 5-h reperfusion. Pretreatment with acenocoumarol given at the dose of 50 or 100 μg/kg/dose reduced morphological signs of acute pancreatitis. These effects were accompanied with a decrease in the pancreatitis-evoked increase in serum activity of lipase and serum concentration of pro-inflammatory interleukin-1β. Moreover, the pancreatitis-evoked reductions in pancreatic DNA synthesis and pancreatic blood flow were partially reversed by pretreatment with acenocoumarol given at the dose of 50 and 100 μg/kg/dose. Administration of acenocoumarol at the dose of 150 μg/kg/dose did not exhibit any protective effect against ischemia/reperfusion-induced pancreatitis. We concluded that pretreatment with low doses of acenocoumarol reduces the severity of ischemia/reperfusion-induced acute pancreatitis.

Abstract
UNLABELLED Previous studies have shown that tachykinins, the largest family of neuropeptides, affect the development of mucosal damage in the stomach and colon. The aim of the study was to assess the influence of tachykinins receptors antagonists on the development of the mucosa injury in the proximal and distal jejunum. MATERIAL AND METHODS Mucosal damage was induced by administration of non-steroidal anti inflammatory drugs (NSAIDs), indomethacin, celecoxib or combination of indomethacin plus celecoxib given intragastrically. NK-1 receptor antagonist (SR 140333), NK-2 receptor antagonist (SR 48968) and NK-3 receptor antagonist (SR 142801) were administered intraperitoneally twice, 30 min before treatment with NSAID and again 24 h later, 30 min before the end of the experiment. RESULTS Administration of indomethacin, a relatively selective inhibitor for cyclooxygenase-1 (COX-1), induced mucosal lesions in the jejunum. Lesions area in the distal jejunum was 8-fold bigger than in the proximal jejunum. This effect was associated with a significant reduction in mucosal blood flow and an increase in mucosal concentration of pro-inflammatory interleukin-1beta (IL-1beta). Celecoxib, selective inhibitor for COX-2 failed to induce mucosal lesions and did not affect the mucosal blood flow and IL-1beta concentration in the proximal and distal jejunum. In rats treated with a combination of indomethacin plus celecoxib, ulcers reached maximal area. This effect was associated with the highest concentration of mucosal IL-1beta and maximal reduction in mucosal blood flow. Administration of NK-1 receptor antagonist, SR 140333 reduced jejunal damage induced by indomethacin given alone or in combination with celecoxib. This effect was associated with significant reduction in mucosal concentration of IL-1beta. Effect of SR 140333 on mucosal blood flow was statistically insignificant. Neither NK-2 nor NK-3 receptor inhibitor affected mucosal blood flow, IL-1beta concentration area of NSAIDs-induced mucosal damage in the jejunum. CONCLUSIONS Blockade of NK-1 receptor protects the jejunum against NSAIDs-induced mucosal injury and reduces local inflammation. This observation indicates the involvement of endogenous tachykinins in deleterious effects of NSAID.

Abstract
UNLABELLED Previous studies have shown that pancreatic ischemic preconditioning or heparin, applied before induction of acute pancreatitis inhibit the development of this disease and accelerate pancreatic recovery. The aim of the study was to determine the influence of treatment with heparin on protective effect of ischemic preconditioning (IP) in ischemia/reperfusion-induced acute pancreatitis. Heparin was administered twice, before and during induction of acute pancreatitis. IP was performed by short-term clamping of celiac artery, 30 min before induction of acute pancreatitis. Acute pancreatitis was induced in rats by clamping of inferior splenic artery for 30 min followed by reperfusion. Rats were sacrificed after 6-h and 24-h reperfusion. RESULTS IP applied alone caused a mild pancreatic damage associated with a limited increase in plasma amylase activity, concentration of pro-inflammatory interleukin-1β and plasma level of D-dimer. Pretreatment with heparin or IP applied alone reduced the severity of acute pancreatitis. Both these procedures caused a similar reduction in plasma lipase, amylase and interleukin-1β, as well as in histological signs of pancreatic damage. These changes were associated with partial reversion of the pancreatitis-evoked fall of pancreatic blood flow and DNA synthesis. Combination of heparin plus IP reduced the protective effect of heparin or IP applied alone. It was manifested by an increase in pancreatic damage and plasma level of lipase, amylase and interleukin-1β, as well as by reduction in pancreatic DNA synthesis and plasma concentration of D-dimer and interleukin-10. CONCLUSIONS heparin abolishes the protective effect of ischemic preconditioning in ischemia reperfusion-induced pancreatitis. This observation suggests that initial clot formation is necessary to induce pancreatic protection by IP.

Abstract
Some recent studies indicate that cannabis may induce acute pancreatitis in humans and administration of anandamide increases the severity of acute pancreatitis; whereas another study exhibits some therapeutic effects in acute pancreatitis. Aim of the present study was to discover what is the reason for these opposite confusing results and to determine the role of sensory nerves in this effect. Acute pancreatitis was induced in rats by cerulein. Anandamide, an endogenous cannabinoid, was administered i.p. (1.5 micromol/kg) before or 2 h after cerulein administration. Stimulation of sensory nerves was performed by capsaicin (0.5 mg/kg s.c.). In rats treated with combination of anandamide plus capsaicin, capsaicin was given 10 min after each dose of anandamide. After the last injection of cerulein or 4 h later, the study was terminated. In our study we observed that stimulation of sensory nerves by capsaicin, before administration of cerulein, reduced the severity of acute pancreatitis. Anandamide, administered alone before cerulein, increased pancreatic damage in acute pancreatitis. Anandamide administered in combination with capsaicin, before cerulein, abolished the capsaicin-induced protective effect on the pancreas. Opposite effects were observed when capsaicin and anandamide were administered after injection of cerulein. Capsaicin increased the severity of acute pancreatitis, whereas anandamide reduced pancreatic damage and reversed the deleterious effect of capsaicin. We conclude that the effect of anandamide on the severity of acute pancreatitis depends on the phase of this disease. Administration of anandamide, before induction of pancreatitis, aggravates pancreatic damage; whereas anandamide administered after induction of pancreatitis, reduces the severity of acute pancreatitis. Sensory nerves are involved in the mechanism of this biphasic effect of anandamide.
