Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Context: The mechanism involved in AD is complex, which has prompted to develop compounds that could simultaneously interact with several potential targets. Here, we report a new synthesized compound SCR-1693 which is designed to target both AChE and calcium channels that are potential for AD therapy.', 'We investigated the effects of SCR-1693 on AChE and calcium channels, the effects of neuroprotection and anti-amnesia in icv-A25-35-injected mice, and the potential mechanisms.', 'AChE activity assay, intracellular Ca(2+) content and calcium currents measurement, and A25-35-induced cellular death determine were performed for validation of designed targets and neuroprotection of SCR-1693. Mice were orally administrated with SCR-1693 once daily after an A25-35 injection. The Morris water maze and Y-maze test, and hippocampal protein detection were conducted on days 5-10, day 11, and day 8. The pyramidal neuron number, hippocampal AChE activity, and synaptic transmission were measured on day 12.', 'SCR-1693 acted as a selective, reversible, and noncompetitive inhibitor of AChE, and a nonselective voltage-gated calcium channel blocker. SCR-1693 also inhibited the increase of AChE activity in the mouse hippocampus. SCR-1693 was more effective than donepezil and memantine in preventing A25-35-induced long-term and short-term memory impairment, maintaining the basal transmission of Schaffer collateral-CA1 synapses, and sustaining LTP in mouse hippocampus. SCR-1693 attenuated A25-35-induced death of SH-SY5Y cell and the loss of hippocampal pyramidal neurons, and regulated A25-35-induced signal cascade in neurons.
Answer: All these findings indicated that SCR-1693, as a double-target-direction agent, is a considerable candidate for AD therapy.

Context: Within Australian hospitals, cardiac and respiratory arrests result in a resuscitation attempt unless the patient is documented as not for resuscitation.', 'To examine the consistency of policies and documentation for withholding in-hospital resuscitation across health services.', 'An observational, qualitative review of hospital policy and documentation was conducted in June 2013 in three public and two private sector hospitals in metropolitan Melbourne. Not for resuscitation (NFR) forms were evaluated for physical characteristics, content, authorisation and decision-making. Hospital policies were coded for alerts, definition of futility and burden of treatment and management of discussions and dissent.', 'There was a lack of standardisation, with each site using its own unique NFR form and accompanying site-specific policies. Differences were found in who could authorise the decision, what was included on the form, the role of patients and families, and how discussions were managed and dissent resolved. Futility and burden of treatment were not defined independently. These inconsistencies across sites contribute to a lack of clarity regarding the decision to withhold resuscitation, and have implications for staff employed across multiple hospitals.
Answer: NFR forms should be reviewed and standardised so as to be clear, uniform and consistent with the legislative framework. We propose a two-stage process of documentation. Stage 1 facilitates discussion of patient-specific goals of care and consideration of limitations of treatment. Stage 2 serves to communicate a NFR order. Decisions to withhold resuscitation are inherently complex but could be aided by separating the decision-making process from the communication of the decision, resulting in improved end-of-life care.

Context: The traditional management of complex penetrating duodenal trauma (PDT) has been the use of elaborate temporizing and complex procedures such as the pyloric exclusion and duodenal diverticulization. We sought to determine whether a simplified surgical approach to the management of complex PDT injuries improves clinical outcome.', 'A retrospective review of all consecutive PDT from 2003 to 2012 was conducted. Patients were divided into three groups according to a simplified surgical algorithm devised following the local experience at a regional Level I trauma center. Postoperative duodenal leaks were drained externally either via traditional anterior drainage or via posterior "retroperitoneal laparostomy" as an alternate option.', 'There were 44 consecutive patients with PDT, and 41 of them (93.2%) were from gunshot wounds. Seven patients were excluded owing to early intraoperative death secondary to associated devastating traumatic injuries. Of the remaining 36 patients, 7 (19.4%) were managed with single-stage primary duodenal repair with definitive abdominal wall fascial closure (PDR + NoDC group). Damage-control laparotomy was performed in 29 patients, (80.5%) in which primary repair was performed in 15 (51.7%) (PDR + DC group), and the duodenum was over sewn and left in discontinuity in 14 (48.3%). Duodenal reconstruction was performed after primary repair in 2 of 15 cases and after left in discontinuity in 13 of 14 cases (DR + DC group). The most common complication was the development of a duodenal fistula in 12 (33%) of 36 cases. These leaks were managed by traditional anterior drainage in 9 (75%) of 12 cases and posterior drainage by retroperitoneal laparostomy in 3 (25%) of 12 cases. The duodenal fistula closed spontaneously in 7 (58.3%) of 12 cases. The duodenum-related mortality rate was 2.8%, and the overall mortality rate was 11.1%.
Answer: An application of basic damage-control techniques for PDT leads to improved survival and an acceptable incidence of complications.
