Article Abstract

Patients with prolonged disorders of consciousness (DOCs) longer than 28 days may continue to make significant gains and achieve functional recovery. Occasionally, this recovery trajectory may extend past 3 (for nontraumatic etiologies) and 12 months (for traumatic etiologies) into the chronic period. Prognosis is influenced by several factors including state of DOC, etiology, and demographics. There are several testing modalities that may aid prognostication under active investigation including electroencephalography, functional and anatomic magnetic resonance imaging, and event-related potentials. At this time, only one treatment (amantadine) has been routinely recommended to improve functional recovery in prolonged DOC. Given that some patients with prolonged or chronic DOC have the potential to recover both consciousness and functional status, it is important for neurologists experienced in prognostication to remain involved in their care.

β-Adrenergic Receptors - Not Always Outside-In.

Canonical activation of G-protein coupled receptors (GPCRs) by hormone binding occurs at the plasma membrane, resulting in the diffusion of second messengers to intracellular effector sites throughout the cell. In contrast, recent evidence suggests that functional GPCRs can induce signaling from distinct intracellular domains, contributing to specificity in signaling. Functional adrenergic receptors have been identified at intracellular sites in the cardiac myocyte such as endosomes, the sarcoplasmic reticulum, the Golgi and the inner nuclear membrane.

Purpose: This review and case report address ligneous conjunctivitis (LC), a rare ocular condition caused by plasminogen deficiency type 1 (PLGD-1), which manifests as wood-like fibrin-rich membranes on the palpebral conjunctiva. The goal is to provide ophthalmologists-often the first physicians to encounter the condition-with a robust understanding of its systemic manifestations and to highlight current therapeutic strategies, with particular emphasis on the administration of intravenous plasminogen concentrate.

Methods: We present a clinical LC case alongside a narrative review of published cases, etiology, and treatment approaches.

From Gut Inflammation to Cardiovascular Conflagration: Mapping IBD's Cardiometabolic Risks.

Curr Atheroscler Rep

Purpose Of Review: This review aims to characterize the known cardiovascular (CV) manifestations associated with inflammatory bowel disease (IBD) and the underlying mechanisms driving these associations.

Recent Findings: Gut dysbiosis, a hallmark of patients with IBD, can result in both local and systemic inflammation, thereby potentially increasing the risk of cardiovascular disease (CVD) in the IBD population. Micronutrient deficiencies, anemia, and sarcopenia independently increase the risk of CVD and are frequent comorbidities of patients with IBD.

In dental practice, it regularly happens: a patient presents with a prolonged pain complaint where there appears to be no sign of tissue damage (any longer). Patients with chronic facial pain may be experiencing altered nociception. This is associated with processes of sensitization and impaired signal inhibition in the somatosensory system.

Small ruminant lentiviruses (SRLVs) are chronic and progressive diseases caused by retroviruses that pose a serious threat to family farming. This study aimed to determine the seroprevalence and risk factors associated with SRLV infection in goats from family farming properties in Alagoas, Northeastern Brazil. In the semiarid region of Alagoas, seventeen family farming properties were visited, distributed across eleven municipalities.
