Background: Tranexamic acid (TXA) has been used to treat traumatic brain injury (TBI); however, no definitive conclusions have been drawn regarding its effectiveness or dosage. This study evaluated the optimal TXA dose for treating TBI using a network meta-analysis (NMA).
Methods: Five databases were searched for peer-reviewed randomized controlled trials (RCTs) published from inception to May 2024.
Background: This study investigated the impact of total knee arthroplasty (TKA) on the alignment of the ankle joint, focusing on changes in coronal alignment of both ankles.
Methods: This retrospective study, conducted at our hospital, included 64 patients older than 70 years who underwent TKA for varus knee osteoarthritis (OA). Using full-length standing radiographs of both lower extremities taken preoperatively and 6 months postoperatively, we assessed ankle OA grading based on the Takakura-Tanaka classification and measured mechanical hip-knee-ankle (mHKA) and the tibiotalar angle (TTA) on both the surgical and contralateral side.
Article Synopsis
- The study aimed to investigate the effects of tranexamic acid (TXA) on mortality and neurological outcomes in children with severe traumatic brain injuries (TBIs).
- The research analyzed data from 342 children under 18 years with severe TBIs and found that TXA use did not significantly affect in-hospital death rates or neurological outcomes at discharge.
- The authors concluded that TXA administration showed no association with improved survival or neurological status, suggesting the need for more prospective trials to evaluate its effectiveness in this population.

Article Synopsis
- A sustainable society needs advanced energy storage devices that are lightweight, compact, long-lasting, and safe, going beyond current battery and supercapacitor technologies.
- Single-walled carbon nanotubes (SWCNTs) show promise for this purpose, as they are tough and can be formed into ropes that store nanomechanical energy.
- These SWCNT ropes can store energy with a density of up to 2.1 MJ/kg, which is significantly higher than mechanical steel springs and three times more than advanced lithium-ion batteries, while also being stable and safe in extreme temperatures.

- * Congenital thrombotic thrombocytopenic purpura (cTTP) was suspected, prompting tests for ADAMTS13 activity, which revealed severely decreased activity but no inhibitors present.
- * The combination of test results and genetic testing in her family confirmed a diagnosis of cTTP, highlighting the need for careful evaluation of ITP patients for potential cTTP during follow-up.
Article Synopsis
- The study aimed to analyze moderate traumatic brain injury (TBI) epidemiology and factors linked to poor neurological outcomes among adults using data from the Japan Trauma Data Bank (2019-2022).
- It involved 1,638 patients, predominantly male with a median age of 73, and found that falls were the most common cause of injury, with notable rates of subdural hematomas and cerebral contusions.
- Key factors such as older age, higher comorbidity, lower Glasgow Coma Scale scores, severe trauma, and the need for mechanical ventilation or craniotomy were linked to worse outcomes, while treatments like tranexamic acid and ICU admission correlated with better results.
Article Synopsis
- Out-of-hospital cardiac arrest (OHCA) varies significantly in causes and severity, affecting outcomes and treatment effectiveness.
- There has been limited research specifically addressing these differences in OHCA.
- This literature review aims to examine prognosis and treatment efficacy based on CA-related waveforms, patient age, and post-cardiac arrest syndrome severity to identify better treatment strategies for improved outcomes.
Kounis syndrome is an acute coronary syndrome (ACS) caused by an allergic reaction that almost always occurs immediately and simultaneously with allergic symptoms. We present a case of Kounis syndrome type III that developed after complete resolution of contrast-induced anaphylaxis in a 60-year-old man with a coronary stent placed in the proximal left anterior descending (LAD) artery branch for ischemic heart disease. Contrast-enhanced computed tomography revealed anaphylactic shock.

- The study focuses on improving the estimation of creatinine clearance (CCr) in older adults with diabetes, emphasizing that body composition changes can affect accuracy.
- Researchers enrolled 50 older Japanese diabetic patients to compare actual CCr measurements with those estimated by the Cockcroft-Gault equation, analyzing body composition factors.
- Results showed that a body fat mass (BFM)-corrected version of the Cockcroft-Gault equation was more accurate, including when BFM was measured using a simple household device, suggesting its potential for everyday clinical use.
A generation, propagation, and transfer of phonon angular momenta are examined on thermal transport in chiral insulative and diamagnetic crystals of α-quartz. We found that thermally driven phonons carry chirality-dependent angular momenta in the quartz crystals and they could be extracted from the quartz as a spin signal. Namely, chirality-induced selectivity of phonon angular momenta is realized in the chiral quartz.
