Objective: Epilepsy is a common neurological disease affecting nearly 1% of the global population, and temporal lobe epilepsy (TLE) is the most common type. Patients experience recurrent seizures and chronic cognitive deficits that can impact their quality of life, ability to work, and independence. These cognitive deficits often extend beyond the temporal lobe and are not well understood.

Herein, we investigate the effects of ligand design on the nuclearity and reactivity of metal-ligand multiply bonded (MLMB) complexes to access an exclusively bimetallic reaction pathway for C-H bond functionalization. To this end, the diiron alkoxide [Fe(Dbf)] () was treated with 3,5-bis(trifluoromethyl)phenyl azide to access the diiron imido complex [Fe(Dbf)(μ-NCHF)] () that promotes hydrogen atom abstraction (HAA) from a variety of C-H and O-H bond containing substrates. A diiron bis(amide) complex [Fe(Dbf)(μ-NHCHF)(NHCHF)] () was generated, prompting the isolation of the analogous bridging amide terminal alkoxide [Fe(Dbf)(μ-NHCHF)(OCH)] () and the asymmetric pyridine-bound diiron imido [Fe(Dbf)(μ-NCHF)(NCH)] ().

The Psychiatric Consultation Service at Massachusetts General Hospital sees medical and surgical inpatients with comorbid psychiatric symptoms and conditions. During their twice-weekly rounds, Dr Stern and other members of the Consultation Service discuss diagnosis and management of hospitalized patients with complex medical or surgical problems who also demonstrate psychiatric symptoms or conditions. These discussions have given rise to rounds reports that will prove useful for clinicians practicing at the interface of medicine and psychiatry.

Myelination is a key biological process wherein glial cells such as oligodendrocytes wrap myelin around neuronal axons, forming an insulative sheath that accelerates signal propagation down the axon. A major obstacle to understanding myelination is the challenge of visualizing and reproducibly quantifying this inherently three-dimensional process in vitro. To this end, we previously developed artificial axons (AAs), a biocompatible platform consisting of 3D-printed hydrogel-based axon mimics designed to more closely recapitulate the micrometer-scale diameter and sub-kilopascal mechanical stiffness of biological axons.

Case: A 51-year-old male polytrauma patient presented with bilateral calcaneus fractures after a fall. This report describes treatment of his right comminuted Sanders IV calcaneus fracture with percutaneous open reduction internal fixation (ORIF) and minimally invasive surgery (MIS) primary subtalar fusion to restore alignment and preserve soft tissue.
Conclusion: Unlike traditional open approaches, which are prone to wound complications due to larger incisions, our approach of maintaining fracture alignment during joint preparation using an MIS burr for acute posttrauma subtalar arthrodesis and percutaneous ORIF appears to have reduced these risks, resulting in successful radiological healing and functional recovery at 1-year follow-up.

Chemical modification of naturally derived glycosaminoglycans (GAGs) expands their potential utility for applications in soft tissue repair and regenerative medicine. Here we report the preparation of a novel crosslinked chondroitin sulfate (~200 to 2000 kilodaltons) that is both soluble in aqueous solution and microfilterable. We refer to these materials as "SuperGAGs.

Context: Trabecular bone score (TBS), a gray-level texture index derived from lumbar spine (LS) dual-energy x-ray absorptiometry (DXA) scans, is decreased in patients with diabetes and is associated with increased fracture risk, independent of areal bone mineral density (aBMD), but potentially influenced by abdominal fat tissue.
Objective: Evaluate effect of romosozumab (210 mg monthly) for 12 months followed by alendronate (70 mg weekly) for 24 months vs alendronate alone (70 mg weekly) for 36 months on LS aBMD and TBS in women with type 2 diabetes (T2D) enrolled in the ARCH study.
Methods: This post hoc analysis included women from ARCH who had T2D at baseline and LS DXA scans at baseline and ≥1 postbaseline visit (romosozumab-to-alendronate, n = 165; alendronate-to-alendronate, n = 195).

The design of new alloys is a multiscale problem that requires a holistic approach that involves retrieving relevant knowledge, applying advanced computational methods, conducting experimental validations, and analyzing the results, a process that is typically slow and reserved for human experts. Machine learning can help accelerate this process, for instance, through the use of deep surrogate models that connect structural and chemical features to material properties, or vice versa. However, existing data-driven models often target specific material objectives, offering limited flexibility to integrate out-of-domain knowledge and cannot adapt to new, unforeseen challenges.

Biofield Therapies, with a historical lineage spanning millennia and continuing relevance in contemporary practices, have been used to address various health conditions and promote wellbeing. The scientific study and adoption of these therapies have been hindered by cultural challenges and institutional barriers. In addition, the current research landscape for Biofield Therapies is insufficiently documented.

We study the problem of testing multiple secondary endpoints conditional on a primary endpoint being significant in a two-stage group sequential procedure, focusing on two secondary endpoints. This extends our previous work with one secondary endpoint. The test for the secondary null hypotheses is a closed procedure.

Importance: Although Medicare Advantage plans frequently offer dental benefits, enrollees report lower rates of dental care use and higher rates of unmet dental need compared with individuals with employer-sponsored benefits. It is unknown which attributes of Medicare Advantage dental plans are associated with enhanced dental care access.
Objective: To determine attributes of Medicare Advantage dental plans associated with higher rates of dental care use and lower rates of unmet dental need.

Circulating monocytes contribute to the defense against pathogens and play a crucial role in maintaining immune homeostasis. While there is substantial evidence regarding the triggers of monocyte activation, our understanding of how monocyte function is restored toward homeostasis after activation remains limited. Here, we assessed the changes in monocyte anisocytosis upon activation in blood, measured by monocyte distribution width (MDW), a biomarker for sepsis.

Importance: Length of custody is a mechanism by which carceral systems can worsen health. However, there are fewer studies examining US immigration detention, in large part because US immigration detention is largely privately operated and opaque by design.
Objectives: To examine the association between duration spent in US immigration detention with subsequent health outcomes.

Importance: Long-term nursing home stay or death (long-term NH stay or death), defined as new long-term residence in a nursing home or death following hospital discharge, is an important patient-centered outcome.
Objective: To examine whether the COVID-19 pandemic was associated with changes in long-term NH stay or death among older adults with sepsis, and whether these changes were greater in individuals from racial and ethnic minoritized groups.
Design, Setting, And Participants: This cross-sectional study used patient-level data from the Medicare Provider Analysis and Review File, the Master Beneficiary Summary File, and the Minimum Data Set.

Background: Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are established treatment options for type 2 diabetes (T2D). In addition to their glycemic benefit, GLP-1 RAs also induce weight loss by suppressing appetite via hypothalamic pathways. However, it remains unclear whether weight reduction is the primary driver of glycemic improvement.

Experiencing music often entails the perception of a periodic beat. Despite being a widespread phenomenon across cultures, the nature and neural underpinnings of beat perception remain largely unknown. In the last decade, there has been a growing interest in developing methods to probe these processes, particularly to measure the extent to which beat-related information is contained in behavioral and neural responses.

Background: Patient and caregiver perspectives are critical in the evaluation of avoidant/restrictive food intake disorder (ARFID); however, little is understood about how caregiver and youth perceptions may differ. This study compared caregiver and youth reports among pediatric patients from an outpatient ARFID program.
Methods: Patients (217 individuals with ARFID, aged 8-17) and their caregivers completed the Nine-Item ARFID Screen (NIAS), a screening tool with parallel youth and caregiver report forms.
