Article Synopsis
  • Alcohol use disorder (AUD) often coexists with anxiety disorders, but it's unclear whether alcohol abuse leads to or results from anxiety issues.
  • Using inbred mice in a risk-avoidance test, researchers found that those showing higher anxiety-like behaviors experienced greater relief from alcohol, indicating a link between anxiety and alcohol consumption.
  • The study revealed that the balance of dopamine D1 and D2 receptors in the brain influences this relationship; a higher D1 to D2 ratio was associated with increased risk-avoidance and continued alcohol use, suggesting that anxiety traits might contribute to developing AUD.

Purpose: To analyze the association between emergent surgery status and systemic adverse outcomes in patients undergoing open orbital floor blowout fracture repair.

Methods: This retrospective cohort analysis utilized the 2005-2018 National Surgery Quality Improvement Program (NSQIP) database. Current Procedural Terminology (CPT) codes were used to identify cases with open treatment of orbital floor blowout fractures (21385, 21386, 21387, 21390, 21395).

Article Synopsis
  • - TFEB and TFE3 (TFEB/3) are important for lysosomal function and autophagy, and their roles vary depending on cell types, particularly in peripheral nerve repair. - The study shows that TFEB/3 is essential for converting Schwann cells into progenitor-like cells after nerve injury; without it, nerve repair is significantly impaired in knock-out mice. - Despite the presence of another regulator, TFEB/3 deficiency hinders the activation of repair-related genes, leading to poor nerve regrowth and recovery, although the breakdown of myelin remains unaffected.

Background: Venous thromboembolism (VTE) is a widespread and significant cause of morbidity and mortality on a global scale. The primary objective of this cross-sectional study is to examine the impact of anticoagulant therapy on major organ hemorrhage events in patients diagnosed with acute venous thromboembolism (VTE). Specifically, this research compares the effects of vitamin K antagonists (VKAs) and direct oral anticoagulants (DOACs).

Objectives: The regulation of various cellular functions such as growth, proliferation, metabolism, and angiogenesis, is dependent on the PI3K pathway. Recent evidence has indicated that kidney renal clear cell carcinoma (KIRC) can be triggered by the deregulation of this pathway. The objective of this research was to investigate 25 genes associated with activation of the PI3K pathway in KIRC and control samples to identify four hub genes that might serve as novel molecular biomarkers and therapeutic targets for treating KIRC.

Objectives: To explore the association between diabetes and outcomes in thyroidectomy patients.

Methods: This retrospective cohort analysis used the 2015-2017 American College of Surgeons National Surgery Quality Improvement Program database. Current Procedural Terminology (CPT) codes were used to identify thyroidectomy cases (60210, 60212, 60220, 60225, 60240, 60252, 60254, 60260, 60270, and 60271).

Diabetic Ketoacidosis (DKA) is a preventable yet serious complication of diabetes that is commonly associated with type 1 diabetes but can also occur in other forms of diabetes, including type 2. Infection is a primary cause of DKA and can lead to elevated levels of procalcitonin (PCT), which is a biomarker used to differentiate bacterial infections from non-infectious inflammation. However, some cases of DKA have shown increased PCT levels even in the absence of bacterial infection, and the underlying mechanism of this observation is not fully understood.

Neurogenic orthostatic hypotension (nOH) is a disabling problem of autonomic dysfunction in patients with Parkinson's disease, which is associated with poor quality of life and higher mortality rates. The purpose of this literature review was to explore and compare the efficacy and safety of droxidopa (an existing treatment) and ampreloxetine (a newer medication) in the treatment of nOH. We used a mixed-method literature review that addresses the epidemiology, pathophysiology, and pharmacological and non-pharmacological management of nOH in Parkinson's disease in a general way, with a more exploratory approach to droxidopa- and ampreloxetine-controlled trial studies.

Background and objective Myasthenia gravis (MG) is an acquired autoimmune disease mediated by antibodies affecting the neuro-muscular junction on the postsynaptic membrane, resulting in neuromuscular transmission obstruction and, consequently, muscle weakening. It is believed that the thymus gland plays a critical role in the production of these antibodies. Screening patients for thymoma and surgical excision of the thymus gland is a crucial part of the treatment.

Virtual reality (VR) and augmented reality (AR) are noble adjunctive technologies currently being studied for the neuro-rehabilitation of post-stroke patients, potentially enhancing conventional therapy. We explored the literature to find if VR/AR improves neuroplasticity in stroke rehabilitation for a better quality of life. This modality can lay the foundation for telerehabilitation services in remote areas.

Background Endoscopic variceal ligation (EVL) is a surgical intervention that can work well to curb variceal bleeding in people with liver cirrhosis. However, it could make ulcer bleeding worse and be fatal in some cases. The widespread use of proton pump inhibitors (PPI) in cirrhotic individuals with variceal bleeding is empirical rather than based on scientific data.

Background Psychogenic non-epileptic seizures (PNES) are often seen as indicators of poor motor and sensory function caused by psychological responses to stressful experiences. A seizure might trigger these reactions. The aim of our study was to assess the structural changes in brain MRI associated with psychogenic non-epileptic seizures.

Background Epilepsy is considered when a patient has at least two unprovoked seizures that occurred more than a day apart. Seizure control depends upon several factors, including adequate treatment and its dosage, patients' daily activities, and adherence to antiepileptic medications. The study aimed to assess the rate of adherence to antiepileptic drugs (AED) in patients with epilepsy.

We describe a case of a severe but rare adverse reaction to recombinant varicella-zoster virus (VZV) vaccination: a 67-year-old female admitted with gradual onset of shortness of breath, hypoxia, and fever following VZV vaccination. The clinical picture and radiologic presentation mimicked COVID-19 pneumonia. However, repeated testing for COVID-19 by PCR was negative.

Iron deficiency is a well-known cause of anemia. However, it is an under-recognized cause of venous thromboembolism (VTE). Iron deficiency predisposes to VTE mainly by inducing thrombocytosis, which can lead to a hypercoagulable state.

COVID-19 infection causes considerable morbidity and mortality, especially to those who are aged, have impaired renal function and are obese. We propose to examine the potential utility of oral activated charcoal with the hypothesis that such treatment would lower absorption of microbiome derived toxins and ameliorate systemic oxidant stress and inflammation.

Objective: To determine the prevalence of excessive daytime sleepiness among medical students and establish a relationship between self-perceived sleepiness and psychological distress.

Methods: In a cross-sectional study, 441 medical students from a public-sector university in Pakistan completed a questionnaire from August to December 2018. The questionnaire included the Epworth Sleepiness Scale (ESS), which measured daytime sleepiness, and the 12-item General Health Questionnaire (GHQ-12), which measured mental health.

None: Excessive daytime sleepiness (EDS) is one of the leading reasons that patients present to sleep clinics. Approximately 10% to 14% of the adults report that excessive sleepiness interferes with their daily lives. Common causes of EDS include obstructive sleep apnea, sleep deprivation, circadian rhythm disorders, medication effects, psychiatric conditions especially depression, and primary hypersomnia such as narcolepsy or central idiopathic hypersomnia.
