S100b protein is a calcium-binding protein that is mainly found in astrocytes and oligodendrocytes of the central nervous system and Schwann cells of the peripheral nervous system.[5] As such, S100β has been investigated as a biomarker for injury to the blood–brain barrier and/or astrocyte injury and has been reported to correlate with the degree of blood–brain barrier destruction and the severity and scope of brain injury.[5–7] Previously, S100β has been correlated with the development of delirium and cognitive changes after surgery in patients who are not critically ill.[6,8–11] Similarly, others have reported that delirium and neurologic outcomes may correlate with S100β in critically ill patients.[6,7,12–14] However, there are significant limitations and gaps in the available literature. The current studies display a predominance of male subjects (up to 65%), advanced age, and low levels of racial diversity among the study groups.[6,7,12–17] All current studies among critically ill populations have all been performed in China (n = 3),[5,12,13] the United States (n = 2),[6,7] Belgium (n = 2),[14,15] the Netherlands (n = 1),[17] or Brazil (n = 1).[16] Furthermore, limitations in study design limit the generalizability of the reported findings, including small sample sizes, differences in the study group populations (trauma vs. medical), differences in illness severity as evidenced by wide ranges on validated illness severity indices, and an absence of randomized studies (e.g. only observational and case–control studies).[5–7,12–17] In addition, the comparability of the preillness baseline health of the study populations across studies is unclear as only the US studies have reported a validated index for this (e.g. the Charlson Comorbidity Index).[5–7,12–17] Among the ICU populations, S100β levels have been reported to positively correlate with ICU LOS and readmission (trauma populations),[5,13] and adverse outcomes (mixed medical/surgical, trauma populations).[13,14] In addition, S100B was negatively correlated with global cognition up to 12 months after hospital discharge in a mixed medical/surg","PeriodicalId":13938,"journal":{"name":"International Journal of Critical Illness and Injury Science","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135596436","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}

The objective of this study was to compare the ankle range of motion and dynamic stability of healthy and injured athletes for their dominant and nondominant legs. Methods: A cross-sectional study design was selected to investigate this study with 32 male soccer players with average age: 22.6 ± 3.3 years, weight: 69.6 ± 5.7 kg, height: 176.8 ± 5.32 cm, with a history of a lateral ankle sprain on the dominant leg for the past 2 years. Ankle range of motion was determined using dorsiflexion and plantar flexion by a goniometer. The dynamic stability was determined using the SWAY medical system. An independent t-test was used to study the differences between healthy and injured groups and between dominant and nondominant legs for dynamic stability, dorsiflexion, and plantar flexion range. Results: There were higher significant differences for dynamic stability in healthy participants than in injured participants for their dominant (P = 0.001) and nondominant (P = 0.001) legs. There were significant differences in dynamic stability in the dominant and nondominant leg (healthy [P = 0.033] and injured [P = 0.000] participants). The dominant leg shows higher dynamic stability in healthy group, whereas nondominant leg shows higher dynamic stability in the injured group. Conclusion: The study found significant differences between the injured and sound legs. The injured dominant and nondominant leg revealed a striking disparity in the ankle range of motion. Therefore, the study demonstrated that ankle sprain causes due to less stability of the ankle joint, which limits ankle movements.","PeriodicalId":13938,"journal":{"name":"International Journal of Critical Illness and Injury Science","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135596440","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}

The foundation of early septic shock management includes early fluid resuscitation, but the association between fluid resuscitation rates and kidney outcomes remains unclear. This investigation examines the association between fluid resuscitation rate and AKI recovery. Methods: In the medical intensive care unit of Mayo Clinic Rochester, adult patients with AKI and septic shock were retrospectively studied from January 1, 2006 to May 31, 2018. The surviving sepsis campaign recommends an initial fluid bolus of 30 ml/kg for sepsis resuscitation. The cohort of patients was divided into three groups based on the average fluid resuscitation time (<1 h, 1.1–3 h, >3 h) and the corresponding fluid rate ≥0.5, 0.17–0.49, and <0.17 ml/kg/min, respectively. The primary outcome was the recovery of AKI on day 7. To account for potential confounders, multivariable regression analyses were conducted. Results: After meeting the eligibility, 597 patients were included in the analysis. The AKI recovery was considerably different among the groups (P = 0.006). Patients in group 1 who received fluid resuscitation faster had a higher rate of AKI recovery (53%) compared to group 2 and group 3 (50% and 37.8%). Conclusion: In septic shock patients with AKI, a higher fluid resuscitation rate of 30 ml/kg IV fluids within the 1st-h sepsis diagnosis (i.e., >0.50 ml/kg/min) lead to higher AKI recovery compared with slower infusion rates.","PeriodicalId":13938,"journal":{"name":"International Journal of Critical Illness and Injury Science","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135596690","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}

Methods: A cross-sectional study was conducted at a tertiary care hospital from 2017 to 2019. All adult internal medicine patients admitted to IMCUs were included. Acute conditions were defined as those of short duration (<3 weeks) that require hospitalization. The APACHE-II score was used to determine the severity of these patients’ illnesses. Results: Mean (standard deviation [SD]) age was 62 (16.5) years, and 493 (49.2%) patients were male.
