Introduction: Neuromodulation has been a staple of treatment for moderate-to-severe chronic refractory pain since the introduction of the first spinal cord stimulator by Norman Shealy in 1967. Appreciating the dynamic nature of electrical modulation of the nervous system from the epidural space, the goal has been consistent, reliable, and therapeutic neural activation of the spinal cord. This has proven to be extremely difficult.

Objectives: To compare success and safety of endotracheal tube (ETT) exchanges with primary intubations and identify factors associated with ETT exchange outcomes.

Design: Retrospective observational study of prospectively collected National Emergency Airway Registry for Neonates data. ETT exchanges are the placement of a new ETT when one is already in place, whereas primary intubations do not have a pre-existing ETT.

Momentum towards legalization of medical and recreational cannabis drives a convergence between natural cannabinoids and their synthetic counterparts, creating new clinical challenges in a second wave of exposures. This review critically examines the emerging challenges posed by synthetic cannabinoid receptor agonists (SCRAs) and semi-synthetic cannabinoids, emphasizing their clinical implications. SCRAs are potent full agonist activity that have been identified as adulterants in several recreational substances, including cannabis and opioids.

Duke Cancer Institute, Duke University School of Medicine, Durham, NC 27710, USA; Department of Pharmacology and Cancer Biology, Duke University School of Medicine, Durham, NC 27710, USA; Department of Pathology, Duke University School of Medicine, Durham, NC 27710, USA. Electronic address:

Recurrent cancer-causing fusions of NUP98 produce higher-order assemblies known as condensates. How NUP98 oncofusion-driven condensates activate oncogenes remains poorly understood. Here, we investigate NUP98-PHF23, a leukemogenic chimera of the disordered phenylalanine-and-glycine (FG)-repeat-rich region of NUP98 and the H3K4me3/2-binding plant homeodomain (PHD) finger domain of PHF23.

Topical insulin in pediatric neurotrophic keratopathy associated with CIPA syndrome.

J AAPOS

February 2025

Department of Ophthalmology, Boston Children's Hospital, Harvard Medical School, Boston, Massachusetts; Department of Ophthalmology, Harvey and Bernice Jones Eye Institute, University of Arkansas for Medical Sciences, Little Rock, Arkansas. Electronic address:

We present a case, with a 2-year follow-up, of the use of topical insulin in managing neurotrophic keratopathy in a 3-year-old boy diagnosed with congenital insensitivity to pain with anhidrosis (CIPA). Initially, the patient had a corneal perforation in the right eye, for which he underwent tectonic amniotic membrane transplantation. On examination, a central corneal ulcer with stromal infiltration was identified in the left eye, accompanied by a complete absence of corneal sensation in both eyes.

In end-stage-kidney-disease (ESKD) hyperphosphatemia occurs secondary to decreased renal elimination with continued intestinal absorption of dietary phosphate. Even in chronic kidney disease, glomerular filtration rate lower than 30 ml/min markedly decreases the filtration of inorganic phosphate and increases its serum level. Sevelamer, a non-calcium phosphate binder, is commonly used to control hyperphosphatemia.

Background: Osteoporosis (OP), characterized by reduced bone mass and mineral density, is a global metabolic disorder that severely impacts the quality of life in affected individuals. Although current pharmacological treatments are effective, their long-term use is often associated with adverse effects, highlighting the need for safer, more sustainable therapeutic strategies. This study investigates the pro-osteogenic and anti-resorptive potential of the secretome from Smurf1-silenced mesenchymal stem cells (MSCs) as a promising cell-free therapy for bone regeneration.

The Tenth International brain-computer interface (BCI) meeting was held June 6-9, 2023, in the Sonian Forest in Brussels, Belgium. At that meeting, 21 master classes, organized by the BCI Society's Postdoc & Student Committee, supported the Society's goal of fostering learning opportunities and meaningful interactions for trainees in BCI-related fields. Master classes provide an informal environment where senior researchers can give constructive feedback to the trainee on their chosen and specific pursuit.

Since 2000, the National Birth Defects Prevention Network (NBDPN), in collaboration with the US National Center on Birth Defects and Developmental Disabilities at the Centers for Disease Control and Prevention, has provided a special issue of Birth Defects Research focused on advancing the field of birth defects surveillance, epidemiology, and public health practice. The annual NBDPN special issue consists of contributed manuscripts using birth defects surveillance data for epidemiologic research or for improving birth defects surveillance methods. This year, our special issue includes updated national prevalence estimates for selected major birth defects, seven original research papers, and an invited editorial.

Plasma cell dyscrasias encompass a spectrum from the precursors monoclonal gammopathy of undetermined significance and smoldering myeloma to symptomatic myeloma, but the genes that enable progression and confer poor prognosis are incompletely understood. Using single cell transcriptomics, we identified the Caseinolytic protease proteolytic subunit (CLPP), a key component of the mitochondrial CLP serine endopeptidase, as being over-expressed in CD138+ neoplastic versus normal, and in symptomatic versus precursor plasma cells. Its high expression was associated with an adverse prognosis across multiple molecularly defined subgroups in the newly diagnosed and relapsed/refractory settings, and with extramedullary disease.

Use of implementation science to qualitatively identify implementation determinants of COPD practice guidelines in primary care.

Chron Respir Dis

February 2025

Behavioral Health Quality Enhancement Research Initiative, Central Arkansas Veterans Healthcare System, North Little Rock, USA.

Chronic Obstructive Pulmonary Disease (COPD) is a progressive respiratory disease with high morbidity and mortality. COPD guidelines (CPG) are greatly underutilized and studies attempting to improve this practice gap have yielded inconsistent results. We hypothesize that using implementation science can provide a detailed understanding of these practice gaps and the reasons behind them.

Background: Previous reports of distal deletions in chromosome 10q in patients have described distinct facial features combined with other neurodevelopmental abnormalities, including intellectual disability. However, the association of interstitial deletions in chromosome 10q with global developmental delay, musculoskeletal abnormalities, and dysmorphic features has not been previously reported.

Methods: Genetic testing using whole exome sequencing (WES) was performed on three patients with neurodevelopmental delay, musculoskeletal abnormalities and dysmorphic features.

With over 200 million people, 50% of Nigeria's population comprises women of reproductive age (15-49 years), making Sexual Reproductive Health and Rights (SRHR) invaluable in achieving SDGs 3 and 5 on health and well-being and gender equality, respectively. Although Nigeria's reproductive health indices have improved over the past two decades, some critical gaps must be closed. We examined SRHR trends in Nigeria using the Nigerian DHS data sets spanning 2003-2018.

Importance: Pediatric patients with chronic kidney disease (CKD) exhibit reduced cerebellum volume, which is associated with neurocognitive deficits and a lower estimated glomerular filtration rate (eGFR), even before dialysis or transplantation. These differences have not been examined within the context of age-related brain changes during childhood to early adulthood.

Objective: To evaluate differences in age-related neurodevelopmental changes in patients with CKD compared with control participants and to investigate associations between regional neuroanatomy, functional outcomes, and disease-related variables.
