Filipinos and Parkinson's disease: A scoping review of the literature.

Background: Filipinos are the third largest sub-group of Asian Americans in the United States and have greater socioeconomic and health disparities than many other Asian sub-groups [1,2,3,4,5,6,7,8]. Characteristics of Filipino patients with Parkinson's disease (PD) have not been adequately studied.

Objective: To scope the extent, range and nature of current knowledge on PD in Filipino-American (FA) patients in contrast to Filipino patients in general.

Sporadic and Recurrent Exertional Rhabdomyolysis.

Horses are particularly susceptible to developing exertional rhabdomyolysis (ER) characterized by muscle stiffness, pain, and reluctance to move. Diagnosis requires establishing abnormal increases in serum creatine kinase activity when horses exhibit clinical signs. The 2 main categories of ER include sporadic ER arising from extrinsic causes and chronic ER that arises from intrinsic continuous or episodic abnormalities in muscle function.

Myosin Heavy Chain Myopathy and Immune-Mediated Muscular Disorders.

Several inflammatory myopathies have an infectious or immune-mediated basis in the horse. Myosin heavy chain myopathy is caused by a codominant missense variant in MYH1 and has 3 clinical presentations: immune-mediated myositis, calciphylaxis, and nonexertional rhabdomyolysis in Quarter Horse-related breeds. An infarctive form of purpura hemorrhagica affects numerous breeds, presenting with focal firm, painful muscle swelling, and subsequent infarction of multiple tissues.

Disorders of Muscle Mass and Tone.

Muscle disease has various clinical manifestations that range from exertional and non-exertional rhabdomyolysis, fasciculations, weakness, rigidity, stiffness, gait abnormalities, poor performance, and alterations in muscle mass and tone. Neurogenic disorders and non-neurogenic disorders such as primary muscle disease can cause muscle atrophy and changes in muscle tone. Myotonic disorders can have a genetic (eg, inherited channelopathies) or acquired (eg, electrolyte derangements) origin.

Genetics of Muscle Disease.

In the field of equine muscle disorders, many conditions have a genetic basis. Therefore, genetic testing is an important part of the diagnostic evaluation. Validated genetic tests are currently available for 5 equine muscle disorders: hyperkalemic periodic paralysis, malignant hyperthermia, glycogen branching enzyme disease, type 1 polysaccharide storage myopathy, and myosin heavy chain myopathy.

Myofibrillar Myopathy.

Myofibrillar myopathy (MFM) is characterized by segmental disarray of myofibrils and ectopic accumulation of a protein called desmin. Previously thought to be a glycogen storage disease, MFM is now recognized as a stand-alone myopathy. Endurance Arabians with MFM usually present with exertional rhabdomyolysis (MFM-ER) at the end of races, elevated serum muscle enzymes, and myoglobinuria.

Management options for vascular anomalies in the distal extremities.

Vascular anomalies arise during embryologic development due to errors in vasculogenesis. They are associated with sporadic or inherited mutations in receptors, growth factors or enzymes within various vasculogenic pathways such as mTOR, VEGF, and PI3K. Vascular anomalies have the capability to cause significant symptoms and disability, especially when located in the distal extremities.

Advances in systematic conservation planning to meet global biodiversity goals.

Systematic conservation planning (SCP) involves the cost-effective placement and application of management actions to achieve biodiversity conservation objectives. Given the political momentum for greater global nature protection, restoration, and improved management of natural resources articulated in the targets of the Global Biodiversity Framework, assessing the state-of-the-art of SCP is timely. Recent advances in SCP include faster and more exact algorithms and software, inclusion of ecosystem services and multiple facets of biodiversity (e.

Crime Victim Compensation: We Can Do Better for Our Children.

Background: Interpersonal injury disproportionately impacts marginalized communities. Crime Victim Compensation (CVC) was developed in Canada and the United States to help individuals and their families following violent injury. In Illinois, the CVC program offers up to $27,000 per claim to assist with mental health, relocation, and burial expenses.

Molecular regulation of mitophagy signaling in tumor microenvironment and its targeting for cancer therapy.

Aberrations emerging in mitochondrial homeostasis are restrained by mitophagy to control mitochondrial integrity, bioenergetics signaling, metabolism, oxidative stress, and apoptosis. The mitophagy-accompanied mitochondrial processes that occur in a dysregulated condition act as drivers for cancer occurrence. In addition, the enigmatic nature of mitophagy in cancer cells modulates the cellular proteome, creating challenges for therapeutic interventions.

Systemic therapy for patients with metastatic pheochromocytoma and paraganglioma.

Pheochromocytomas and paragangliomas are rare neuroendocrine tumors derived from the paraganglia. These tumors frequently secrete excessive amounts of catecholamines leading to cardiovascular and gastrointestinal complications. While all pheochromocytomas and paragangliomas possess the potential for metastasis, actual metastatic occurrences are observed in approximately one third of cases.

Posterior fossa ring-enhancing lesions in the adult immunocompetent host: illustrative cases, systematic review, and proposed diagnostic algorithm.

Purpose: Posterior fossa ring-enhancing lesions (PFREL) in the adult immunocompetent hosts pose a diagnostic challenge. We aimed to evaluate the spectrum of PFREL etiologies and propose a diagnostic algorithm.

Methods: This study involved a retrospective analysis of PFREL cases from our institution (January 2023 to April 2024) and a systematic literature review conducted using Embase and PubMed databases following the PRISMA 2020 guidelines.

Effects of psilocybin on mouse brain microstructure.

Background And Purpose: There is surging interest in the therapeutic potential of psychedelic compounds like psilocybin in the treatment of psychiatric illnesses like major depressive disorder (MDD). Recent studies point to the rapid antidepressant effect of psilocybin; however, the biological mechanisms underlying these differences remain unknown. This study determines the feasibility of using diffusion MRI to characterize and define the potential spatiotemporal microstructural differences in the brain following psilocybin treatment in C57BL/6J male mice.

Downmodulation of potassium conductances induces epileptic seizures in cortical network models via multiple synergistic factors.

Voltage-gated potassium conductances [Formula: see text] play a critical role not only in normal neural function, but also in many neurological disorders and related therapeutic interventions. In particular, in an important animal model of epileptic seizures, 4-aminopyridine (4-AP) administration is thought to induce seizures by reducing [Formula: see text] in cortex and other brain areas. Interestingly, 4-AP has also been useful in the treatment of neurological disorders such as multiple sclerosis (MS) and spinal cord injury, where it is thought to improve action potential propagation in axonal fibers.

PMP2+ Schwann cells maintain the survival of large-caliber motor axons.

Neurodegenerative diseases of both the central and peripheral nervous system are characterized by selective neuronal vulnerability, i.e., pathology that affects particular types of neurons.

Time persistence of the fMRI resting-state functional brain networks.

Time persistence is a fundamental property of many complex physical and biological systems; thus understanding the phenomenon in the brain is of high importance. Time persistence has been explored at the level of stand-alone neural time-series, but since the brain functions as an interconnected network, it is essential to examine time persistence at the network level. Changes in resting-state networks have been previously investigated using both dynamic (i.

Change in subjective well-being and the associated costs of a woman-targeted presbyopia correction programme among older craftswomen in Zanzibar: a cost-outcome and scenario analysis.

Background: A pilot eyecare programme aimed to address the urgent eye health needs of older Zanzibari craftswomen. We investigated the impact of correcting presbyopia on their subjective well-being (SWB) 6 months post-correction and assessed the cost-effectiveness of a women-targeted presbyopia correction programme.

Methods: This study involved Zanzibari craftswomen aged 40 and older with presenting and corrected distance visual acuity better than 6/12 in both eyes and were presbyopic.

The Rbfox1/LASR complex controls alternative pre-mRNA splicing by recognition of multipart RNA regulatory modules.

The Rbfox proteins regulate alternative pre-mRNA splicing by binding to the RNA element GCAUG. In the nucleus, most of Rbfox is bound to the large assembly of splicing regulators (LASR), a complex of RNA-binding proteins that recognize additional RNA motifs. However, it remains unclear how the different subunits of the Rbfox/LASR complex act together to bind RNA and regulate splicing.

Histone bivalency in CNS development.

Neuronal maturation is guided by changes in the chromatin landscape that control developmental gene expression programs. Histone bivalency, the co-occurrence of activating and repressive histone modifications, has emerged as an epigenetic feature of developmentally regulated genes during neuronal maturation. Although initially associated with early embryonic development, recent studies have shown that histone bivalency also exists in differentiated and mature neurons.

Winding up to wind down: designing the end of one's medical career with intentionality.

Background: Physicians are planful beings, spending much time imagining and trying to design their ideal careers. Yet, despite actuarial expectations that physicians may spend almost two decades in retirement, it is paradoxical that little attention is generally given to designing an ideal retirement.

Methods: The coauthors are physicians in the latter parts of their careers who both teach leadership to physicians and have thought deeply about physician transitions, including retirement.
