Background: Seizures are common neurological emergencies in the elderly that are frequently provoked. Geriatrics have higher rates of neurological disorders and other comorbidities that could affect seizure threshold.
Case Presentation: An 83-year-old male Arabic patient presented to the emergency department with an acute confusional state and urinary incontinence followed by a witnessed tonic-clonic seizure in the hospital. Thorough investigations and imaging were positive only for nonspecific magnetic resonant imaging findings with a negative electroencephalogram. The patient was diagnosed with provoked seizure due to over-the-counter cold medications that included pseudoephedrine and caffeine. He was not prescribed antiepileptic medications at discharge and did not develop subsequent seizures up to this date.
Conclusion: Over-the-counter cough and cold medications with sympathomimetic ingredients can be associated with provoked seizures in the elderly. Physicians should be aware of the potentially serious adverse events associated with commonly used nonprescription sympathomimetics such as pseudoephedrine and caffeine in elderly patients.

Prolonged Preservation of up to 24h at 10°C does not Impact Outcomes after Lung Transplantation.

Objective: To determine the impact of prolonged storage of donor lungs at 10°C of up to 24h on outcome after lung transplantation.
Background: An increasing body of evidence suggests 10°C as the optimal storage temperature for donor lungs. A recent study showed that cold ischemic times can be safely expanded to >12h when lungs are stored at 10°C.

Several studies suggest that children and adolescents with autism spectrum disorder (ASD) often present deficits in executive functions (EFs). The research on cold EF shows a high heterogeneity across different cohorts of patients as well as different study designs, while studies investigating hot EF and their relationship with different ASD phenotypes are still limited and related only to specific domains, although this concept could contribute to clarify the phenotypical variability by explaining the difficulties encountered by individuals with ASD in daily life, where stimuli are often emotionally charged. With the aim to identify specific neuropsychological profiles in children and adolescents with ASD without intellectual disability, we designed a study protocol comparing a clinical sample of individuals with ASD to aged-matched (10-17 years) typically developing controls (TDC) on a neuropsychological test battery investigating both "cold" and "hot" EF with the purpose of further investigating their relationships with ASD symptoms.

Since December 2019, a new form of Severe Acute Respiratory Syndrome (SARS) has emerged worldwide, caused by SARS coronavirus 2 (SARS-CoV-2). This disease was called COVID-19 and was declared a pandemic by the World Health Organization in March 2020. Symptoms can vary from a common cold to severe pneumonia, hypoxemia, respiratory distress, and death.

Background: Hemorrhagic fever with renal syndrome (HFRS) is a climate-sensitive zoonotic disease that poses a significant public health burden worldwide. While previous studies have established associations between meteorological factors and HFRS incidence, there remains a critical knowledge gap regarding the heterogeneity of these effects across diverse epidemic regions. Addressing this gap is essential for developing region-specific prevention and control strategies.

Objectives: This study aimed to compare the marginal adaptation of a cold ceramic (CC) sealer with the single-cone obturation technique with that of an AH-26 sealer with the lateral compaction technique in single-canal teeth.
Materials And Methods: In this in vitro experimental study, the root canals of 24 extracted single-rooted single-canal teeth were instrumented to F3 files by the crown-down technique and randomly assigned to 2 groups (n = 12). The root canals were obturated with a CC sealer and single-cone obturation technique with 4% gutta-percha in group 1 and with an AH-26 sealer and lateral compaction technique with 2% gutta-percha in group 2.
