Article Abstract

Objective: In this study, we enrolled patients with acute brain injury (ABI) to examine the relationship between paroxysmal sympathetic hyperactivity (PSH) and volume status, right heart function, and pulmonary edema, and their impact on prognosis.

Methods: Thirty patients with ABI were prospectively enrolled. A correlation analysis between Paroxysmal Sympathetic Hyperactivity Assessment Measure (PSH-AM) score and clinical indicators was performed using Pearson's or Spearman correlation coefficient. Receiver operating characteristic (ROC) curves were used to assess the prediction of 6-month Glasgow Outcome Scale Extended (GOSE) score. Inferior vena cava (IVC) diameter was evaluated as a marker of intravascular volume status, and its correlation with 6-month GOSE score in ABI patients was analyzed.

Results: There was no statistically significant difference in PSH-AM over time in patients with ABI ( = 0.791). The PSH-AM scores on Days 3 ( = 0.474, = 0.08) and 5 ( = 0.460, = 0.011) were positively correlated with pulmonary edema score. Early diastolic velocity (EDV) on Days 3 (R = -0.429, = 0.018) and 5 ( = -0.452, = 0.012) was negatively correlated with pulmonary edema score. Ejection time (ET) on Day 5 was positively correlated with inferior vena cava (IVC) ( = -0.381, = 0.038). The ability to assess the 6-month GOSE score and the ROC curve (AUC) was observed for IVC on Day 1 (AUC = 0.785± 0.120, 95% confidence interval 0.550-1.000, = 0.012).

Conclusion: IVC diameter assessed on day 1 is a useful indicator of neurological prognosis in patients with ABI. There was no statistically significant difference in PSH over time in patients with ABI. Regarding the study's sample size and potential operator bias in IVC diameter measurement, the findings require validation in larger, multicenter studies with standardized measurement protocols.

Background: During recovery from an acquired brain injury (ABI), social isolation is a common experience that can lead to adverse outcomes. Although social connection is known to play a critical role in alleviating these effects, the ways in which ABI survivors experience and prioritise connection and isolation are not well understood. This review aims to understand how these concepts are perceived, identify the valued outcomes, and examine the social contexts that shape these experiences.

The high incidence and prevalence of herpes infections pose a significant health burden worldwide. Herpes simplex virus infections are the cause of herpes labialis, genital herpes or herpes keratitis and in rare cases life-threatening herpes encephalitis, meningitis or disseminated disease. After primary infection herpes simplex viruses (HSVes) establish latency in the trigeminal and sacral ganglia and at least 30% of patients experience clinically manifestant recurrences for life.

Background: Peripheral artery disease (PAD) is a critical manifestation of systemic atherosclerosis, significantly affecting vascular health. Insulin resistance (IR) plays a central role in PAD pathophysiology. The triglyceride-glucose index (TyGI), a recognized marker of IR, has limited evidence regarding its association with PAD.

ObjectiveCombined iliofemoral endarterectomy and iliac stenting (IFE + S) is a proven surgical approach for TransAtlantic Inter-society Consensus (TASC) C and D aortoiliac occlusive disease (AIOD). Iliac stenting alone (ISA) may be an attractive, minimally invasive option in select cases; however, untreated moderate-to-severe common femoral disease may threaten iliac stent patency and limit symptom improvement. This study evaluates the mid-term patency rates after IFE + S versus ISA for TASC C and D AIOD as well as the rate of interval femoral endarterectomies in those who underwent ISA.

Objective: This study aims to evaluate long-term auditory outcomes in patients with inner ear malformations (IEMs) treated with cochlear or auditory brainstem implants (CI/ABI), and to assess the influence of anatomical subtype, electrode design, insertion depth, and genetic/syndromic background on hearing performance over a 10-year follow-up.

Methods: We conducted a prospective cohort study including patients with radiologically confirmed IEMs and bilateral severe-to-profound hearing loss, all of whom underwent implantation and completed at least 10 years of follow-up. Outcomes were assessed using pure-tone average (PTA) and speech recognition scores (SRS) at defined intervals.
