Objective: To identify and evaluate factors associated with delayed recognition of pulmonary tuberculosis (TB) in the emergency department (ED).
Background: Delayed recognition of pulmonary TB in ED may precipitate mortality and morbidity.
Methods: Medical records of newly diagnosed TB patients admitted to four hospitals in Taiwan were retrospectively reviewed. Patients were divided into two groups based on ED physicians' recognition or not of TB and statistically compared to identify differences in their characteristics.
Results: 310 newly diagnosed TB patients were identified; 150 were unrecognized in the ED. Cough, chest tightness, general malaise, and body weight loss were more common for those with recognized TB. Older age (≥65 yrs, P = 0.035) and chronic renal insufficiency (P = 0.005) were associated with delayed TB recognition.
Conclusion: Older age and chronic renal insufficiency are risk factors for delayed TB while in the ED. Typical symptoms should heighten alertness for recognizing TB.

Introduction: Axial spondyloarthritis (axSpA) is a chronic inflammatory condition associated with considerable pain and impaired health-related quality of life (HRQoL) for affected patients. Despite the documented increase in healthcare resource utilization (HRU) related to axSpA, few studies have explored the impact of diagnostic delays on these outcomes. This study sought to determine the association between diagnostic delay of axial spondyloarthritis (axSpA) and costs in the 3 years after diagnosis.

Purpose Of Review: Prader-Willi (PWS) and Angelman (AS) syndromes arise from errors in 15q11-q13 imprinting. This review describes recent advances in genomics and how these expand our understanding of these rare disorders, guiding treatment strategies to improve patient outcomes.
Recent Findings: PWS features include severe infantile hypotonia, failure to thrive, hypogonadism, developmental delay, behavioral and psychiatric features, hyperphagia, and morbid obesity, if unmanaged.
From biological marker to clinical application: the role of anti-Müllerian hormone (AMH) for delayed puberty and idiopathic non-obstructive azoospermia in males.

Anti-Müllerian hormone (AMH), a biomarker secreted by Sertoli cells in the testes, has emerged as a critical indicator of male reproductive function with significant clinical application potential. AMH reflects Sertoli cell activity and plays a pivotal role across different stages of male gonadal function. Firstly, in prepubertal males, AMH levels are crucial for assessing testicular development and the progression of puberty, with delayed or insufficient AMH secretion often being associated with disorders like delayed puberty.

Objective: Temporal lobe epilepsy with hippocampal sclerosis (HS) is a surgically remediable syndrome. We determined temporal trends in the prevalence of hippocampal sclerosis surgeries and related factors.
Methods: We analysed a prospective cohort of adults who underwent epilepsy surgery at the NHNN, London, between 1990 and 2019.
Transcranial Doppler Arterial Pressure Gradient Is Associated With Delayed Infarction After Subarachnoid Hemorrhage.

Background And Purpose: While the pulsatility index (PI) measured by transcranial Doppler (TCD) has broader associations with outcomes in neurocritical care, its use in monitoring delayed cerebral infarction (DCI) in patients with aneurysmal subarachnoid hemorrhage (SAH) is not endorsed by current clinical guidelines. Recognizing that arterial pressure gradient (ΔP) can be estimated using PI, we investigated the potential significance of TCD-estimated ΔP.
Methods: In this observational study of 186 SAH patients, we recorded the mean cerebral blood flow velocity (mCBFV) and PI values from the middle cerebral artery, along with corresponding blood pressures.
