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.

Antithrombotic resumption after middle meningeal artery embolization or surgery for chronic subdural hematoma: a systematic review and meta-analysis.

Background: The periprocedural management of antithrombotic medications in patients with chronic subdural hematoma (cSDH) after middle meningeal artery embolization (MMAE) or surgical evacuation is uncertain.

Methods: A systematic review was conducted across Medline, Embase, and Web of Science databases. We pooled proportions and risk ratios (RRs) for the meta-analysis with the corresponding 95% CIs.

Long-term follow up from the Harvard Alumni Health Study: collegiate sport participation in males is associated with higher physical activity throughout midlife.

Objective: To compare physical activity (PA) over midlife between (1) former collegiate athletes and non-athletes and (2) among athletes in different sports.

Methods: The Harvard Alumni Health Study (HAHS) is a prospective cohort study of male undergraduates who completed serial questionnaires regarding PA and health status between 1962 and 1993. PA was categorised by intensity (<3 METs, light; 3 to <6 METs, moderate; ≥6 METs, vigorous), and energy expenditure (kilocalories (kcal)/week) was estimated at each intensity and in total.

Low-coverage whole genome sequencing of low-grade dysplasia strongly predicts advanced neoplasia risk in ulcerative colitis.

Background: The risk of developing advanced neoplasia (AN; colorectal cancer and/or high-grade dysplasia) in ulcerative colitis (UC) patients with a low-grade dysplasia (LGD) lesion is variable and difficult to predict. This is a major challenge for effective clinical management.

Objective: We aimed to provide accurate AN risk stratification in UC patients with LGD.

Tracking transmission through transposable elements in uropathogenic and commensal .

Aim: To investigate the nucleotide sequences associated with transposable elements carrying bla allelic variants as potential markers for the transmission of antimicrobial resistance genes between domestic animals, humans and the environment.

Materials & Methods: We conducted whole-genome sequencing and analyzed the nucleotide sequences of most abundant bla allelic variants (bla, bla, and bla) in commensal Escherichia coli ( = 20) from household members in Quito and uropathogenic E. coli (UPEC) ( = 149) isolated from nine clinics in Quito, Ecuador.

Timing and Outcomes of PCI in Conjunction With TAVR With Balloon-Expandable Valves.

Background: The optimal timing for percutaneous coronary intervention (PCI) in patients undergoing transcatheter aortic valve replacement (TAVR) is debatable.

Objectives: The aim of this study was to compare outcomes based on the timing of PCI in stable coronary artery disease patients undergoing TAVR.

Methods: Leveraging the STS/ACC TVT Registry and Medicare Linkage, we analyzed patients with stable coronary artery disease undergoing PCI and TAVR between 2015 and 2023 using the SAPIEN 3 balloon-expandable valve platform.

Clinical, Psychosocial, and Ethical Consideration in Assisted Reproductive Technology in Lesbian, Gay, Bisexual, Transgender and Queer+ Populations.

When evaluating reproductive care for lesbian, gay, bisexual, transgender, and queer+ patients, there are multiple factors that must be addressed from a clinician, clinic, and social standpoint. Clinicians should be trained in culturally humble and trauma-informed care; clinics should have intake forms that identify sexual orientation, gender identity, and pronouns. The clinic environment should be inclusive, with all gender or single-stall bathrooms, and patient-facing educational materials that are representative of individuals with diverse partnerships, races, and ethnicities.

Post-traumatic Stress Disorder and the Mental Burden Resulting from the Dobbs Decision.

The obstetrics and mental health care fields have significant crossover. Women with unintended, undesired, or medically complex pregnancies are at greater risk of adverse mental health outcomes, which have the capacity to create long-lasting and intergenerational ripple effects within their larger family unit. Given the frequency with which women seek pregnancy terminations, the numerous factors that influence care accessibility, and the serious repercussions that stem from insufficient use of evidence-based care surrounding pregnancy termination, women are at risk of experiencing a range of mental health outcomes based on their experiences around pregnancy termination.

Use of Telehealth as an Adjunct to Conventional Mental Health Care.

The lack of resources for mental health diagnosis and treatment contributes greatly to maternal morbidity and mortality. Social and cultural barriers, along with the impact of social determinants of health create burdens that prevent mothers from accessing care and treatment. Telehealth care improves access and is widely accepted by clinicians, patients, and their families by reducing need for in person visits, providing privacy, and decreasing costs.

Mental Well-being in Menopause.

The hormonal changes that accompany the transition to menopause are disruptive to most women, and for some, mental health maybe adversely affected. Depressive symptoms and major depression are the best-studied conditions in association with menopause, but anxiety, executive function, and comorbid pre-existing psychiatric conditions all influence the symptomatology that women will experience during this phase of their lives. The epidemiology, diagnosis, and evidence-based treatment guidelines for perimenopausal patients are discussed.
