Methods and\u0000Study Design: We conducted a study of adult septic patients in Intensive Care\u0000Unit (ICU), collecting 47 indicators for 14 days. After data cleaning and\u0000preprocessing, we used stats to explore energy delivery in deceased and\u0000surviving patients. We filtered out nutrition-related features and divided the\u0000data into three metabolic phases: acute early, acute late, and rehabilitation.\u0000Models were built using data before September 2020 and validated on the rest.\u0000We then established optimal energy target models for each phase using deep\u0000learning. Results: A total of 277 patients and 3115 data were included in this\u0000study. The models indicated that the optimal energy targets in the three phases\u0000were 900kcal/d, 2300kcal/d, and 2000kcal/d, respectively. Excessive energy\u0000intake increased mortality rapidly in the early period of the acute phase.\u0000Insufficient energy in the late period of the acute phase significantly raised\u0000the mortality of septic patients. For the rehabilitation phase, too much or too\u0000little energy delivery both associated with high mortality. Conclusion: Our\u0000study established time-series prediction models for septic patients to optimize\u0000energy delivery in the ICU. This approach indicated the feasibility of\u0000developing nutritional tools for critically ill patients. We recommended\u0000permissive underfeeding only in the early acute phase. Later, increased energy\u0000intake may improve survival and settle energy debts caused by underfeeding.","PeriodicalId":501219,"journal":{"name":"arXiv - QuanBio - Other Quantitative Biology","volume":"2017 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139771452","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the literature review\u0000indicates that goals such as maintaining a reasonable scope for innovation, or\u0000more ambitiously to foster a huge bioeconomy don't necessarily contrast with\u0000biosafety, but need to go hand in hand. This paper presents a literature review\u0000of the issues and describes emerging frameworks for policy and practice that\u0000transverse the options of command-and control, stewardship, bottom-up, and\u0000laissez-faire governance. How to achieve early warning systems that enable\u0000prevention and mitigation of future AI-enabled biohazards from the lab, from\u0000deliberate misuse, or from the public realm, will constantly need to evolve,\u0000and adaptive, interactive approaches should emerge. Although biorisk is subject\u0000to an established governance regime, and scientists generally adhere to\u0000biosafety protocols, even experimental, but legitimate use by scientists could\u0000lead to unexpected developments.

For example,\u0000pleasant weather may mean that people spend more time outside doing physical\u0000activity and exposed to the weather, leading to more (or less) pain, and poor\u0000weather or severe pain may keep people inside, sedentary, and not exposed to\u0000the weather. We conducted a smartphone study where participants with chronic\u0000pain reported daily pain severity, as well as time spent outside. We address\u0000the relationship between four weather variables (temperature, dewpoint\u0000temperature, pressure, and wind speed) and pain by proposing a three-step\u0000approach to untangle their effects: (i) propose a set of plausible directed\u0000acyclic graphs (also known as DAGs) that account for potential roles of time\u0000spent outside (e.g., collider, effect modifier, mediator), (ii) analyze the\u0000compatibility of the observed data with the assumed model, and (iii) identify\u0000the most plausible model by combining evidence from the observed data and\u0000domain-specific knowledge. We found that the data do not support time spent\u0000outside as a collider or mediator of the relationship between weather variables\u0000and pain. On the other hand, time spent outside modifies the effect between\u0000temperature and pain, as well as wind speed and pain, with the effect being\u0000absent on days that participants spent inside and present if they spent some or\u0000all of the day outside.

The thallus of brown seaweeds of the order\u0000Laminariales (kelps) is morphologically complex but there is limited\u0000information about the variation in metal accumulation between the different\u0000parts, which might result in erroneous conclusions being drawn if not accounted\u0000for in the biomonitoring protocol.
