Trauma patients are at high risk for developing venous thromboembolism (VTE). The VTE rate when enoxaparin sodium is dosed by anti-factor Xa (anti-Xa) trough level not well described.To determine whether targeting a prophylactic anti-Xa adjusting the dose would reduce in trauma patients.Single-institution, historic vs prospective cohort comparison study an urban, academic, I center. was enrolled from August 2014 to May 2015 and compared with admitted 2013 2014. who received adjusted...

Background Ground level falls (GLFs) among older adults are responsible for millions of injuries. Routine pan-scanning (CT imaging the head, chest, abdomen and pelvis) is commonly employed; however, we lack robust evidence its benefit. We investigated whether identifies a larger proportion patients with significant injury or requiring procedural intervention hypothesized resuscitation area findings—including radiographs, ultrasound, external signs injury—would detect these Methods queried...

BACKGROUND β-Adrenergic receptor blockers (BBs) administered after trauma blunt the cascade of immune and inflammatory changes associated with injury. BBs are improved outcomes traumatic brain injury (TBI). Propranolol may be an ideal BB because its nonselective inhibition ability to cross blood-brain barrier. We determined if early administration propranolol TBI is lower mortality. METHODS All adults (age ≥ 18 years) moderate-to-severe (head Abbreviated Injury Scale [AIS] score, 3–5)...

Background The effect of dyslipidemia on kidney disease outcomes has been inconclusive, and it requires further clarification. Therefore, we aimed to investigate the effects genetic factors association between risk chronic (CKD) using polygenic score (PRS). Methods We analyzed data from 373,523 participants UK Biobank aged 40–69 years with no history CKD. Baseline included plasma levels total cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density (HDL-C), triglyceride, as...

Child restraint systems (CRS) are essential in preventing injury during road traffic collisions, yet neonatal CRS discharge programmes lacking worldwide. Trained healthcare providers have reported a lack of confidence providing advice discharge.

<h3>Importance</h3> Continuous renal replacement therapy (CRRT) benefits patients with failure who are too hemodynamically unstable for intermittent hemodialysis. The duration of beyond which continued use is futile, particularly in a population admitted to and primarily cared by surgical service (hereinafter referred as patients), unclear. <h3>Objective</h3> To analyze proportions independent risk factors survival discharge after initiation CRRT among intensive care unit (SICU). <h3>Design,...

Health risks due to climate change are emerging, particularly from high-temperature exposure. The perceived temperature is an equivalent based on the complete heat budget model of human body. Therefore, we aimed analyze effect overall mortality among patients with chronic kidney disease. In total, 32,870 disease in Seoul participated this retrospective study (2001–2018) at three medical centers. during summer season was calculated using meteorological factors, including air near automated...

Concussion injury is the most common form of traumatic brain (TBI). How recurrent concussions alter long-term outcomes poorly understood, especially as related to development neurodegenerative disease. We evaluated functional and pathological consequences repeated TBI over time in wild type (WT) rats well harboring human SOD1 mutation ("SOD1"), a model familial amyotrophic lateral sclerosis (ALS).A total 42 rats, 26 WT 16 SOD1, were examined study period 25 weeks (or endpoint).

Field intubation (FI) by emergency medical service personnel on severely injured trauma patients remains a contentious practice. Clinical studies suggest an association between FI and adverse outcomes in with traumatic brain injury. Military tactical casualty care recommends deferring providing supplemental oxygenation until reaching more equipped destination. In addition, animal models penetrating hemorrhagic shock demonstrate increased acidosis before resuscitation. The purpose of this...

Background Splenorrhaphy was once used to achieve splenic preservation in up 40% of injuries. With increasing use nonoperative management and angioembolization, operative therapy is less common injuries treated operatively are usually high grade. Patients often unstable, making salvage unwise. Modern surgeons may no longer possess the knowledge perform splenorrhaphy. Methods The records adult trauma patients with from September 2014 November 2018 at an urban level I center were reviewed...

Abstract Anemia is a common complication of chronic kidney disease (CKD), impacting long-term outcomes such as mortality and morbidity. Analyzing NHANES data from 1999 through 2016 for adults aged ≥ 20 years, we assessed the mediating effects anemia biomarkers (hemoglobin, hematocrit, red cell distribution width [RDW], mean corpuscular hemoglobin concentration [MCHC]) on CKD-related by using hazard ratios biomarker-adjusted model. Of 44,099 participants, 7463 experienced all-cause death. Cox...

Abstract Background This study investigated the effect on mortality of transfusing ABO‐incompatible plasma from all sources during trauma resuscitation. Methods Demographic, transfusion, and survival data were retrospectively extracted civilian patients. Patients divided by receipt any quantity blood product (incompatible group) or solely ABO‐compatible (compatible group). The primary outcome was 30‐day mortality, while other outcomes included 6‐ 24‐hour mortality. Mixed‐effects logistic...
