Background: Postmastectomy autologous breast reconstruction can be immediate or delayed. The safety of performing immediate breast reconstruction (IBR) and the impact of radiation on the newly reconstructed breast is not yet validated.
Methods: A PubMed, Embase, and Google scholar search was conducted from inception to September 17, 2023.
Background: Fresh autologous cranial bone graft has traditionally been regarded as the ideal cranioplasty material; however, long-term comparisons of outcomes with modern alloplastic materials are absent in the literature. The authors evaluated complications and failures among cranioplasties performed with fresh, heterotopic, cranial bone graft versus 3 common alloplastic materials.
Methods: Random-effects meta-analyses of logit-transformed proportions were performed on studies published between 1971 and 2021 to evaluate complications and failures of cranioplasties performed with fresh, autologous, heterotopic cranial bone; polyetheretherketone (PEEK); polymethylmethacrylate (PMMA); or titanium with a mean follow-up of 12 months or more.

Objective: To evaluate the role of psychosocial well-being on perioperative pain and opioid use among patients with cleft lip and palate (CLP) undergoing alveolar bone grafting (ABG).
Design: Retrospective review.
Setting: Tertiary level craniofacial clinic.
Background: Racial/ethnic and gender disparities persist in plastic surgery at nearly all levels of training, becoming more pronounced at each stage. Recent studies have demonstrated that the proportion of female plastic surgery residents has increased to nearly 40%, yet only 11% of full professors of plastic surgery are female. Other studies have identified severe declines in underrepresented minority plastic surgery representation between plastic surgery residents and academicians with only 1.

In skull defect reconstruction, nanoparticulate mineralized collagen glycosaminoglycan scaffolds (MC-GAG) have demonstrated osteogenic and anti-osteoclastogenic properties, culminating in the ability to partially heal in vivo skull defects without the addition of exogenous growth factors or progenitor cell loading. In an effort to reduce catabolism during early skull regeneration, we fabricated a composite material (MCGO) of MC-GAG and recombinant osteoprotegerin (OPG), an endogenous anti-osteoclastogenic decoy receptor.

Background: Comprehensive analyses of psychosocial outcomes after gender-affirming FFS are absent in the literature resulting in a paucity of information on the impact of FFS on quality of life as well as ramifications in health insurance coverage of FFS.
Methods: Scores from 11 validated, quantitative instruments from the Patient-Reported Outcomes Measurement Information System (PROMIS) assessing anxiety, anger, depression, global mental health, global physical health, satisfaction with sex life, positive affect, emotional support, social isolation, companionship, and meaning and purpose.
Objective: The current study investigated the influence of the coronavirus (COVID-19) pandemic on patients with congenital craniofacial diagnoses.
Methods: Patients (n = 66) with craniofacial diagnoses aged between 8 and 17 were prospectively evaluated with longitudinal psychosocial assessments using the anger, anxiety, depressive symptoms, and peer relationships instruments within the pediatric Patient-Reported Outcomes Measurement Information System (PROMIS). The COVID-19 cohort (n = 33) included patients with assessments within 2 years prior to the pandemic (t0) and during the pandemic (t1; March 2020 to March 2021).
Introduction With the expanding use of point-of-care ultrasound throughout medical specialties for the rapid bedside assessment integral to patient care, medical schools have sought to incorporate ultrasound education into their curriculum. Second-year medical students (MS2s) at our institution met this demand by forming the Ultrasound Student Instructor Cadre (USSIC), a longitudinal ultrasound curriculum where MS2s teach first-year medical students (MS1s). The objectives of this study were to assess the ultrasound knowledge of medical students and their perceptions of ultrasound incorporation into their medical education.

The nanoparticulate mineralized collagen glycosaminoglycan (MC-GAG) scaffold is shown to promote skull regeneration in vivo without additive exogenous growth factors or progenitor cells, suggesting potential for clinical translation. This work evaluates modulation of MC-GAG stiffness on canonical Wnt (cWnt) signaling.

Reactivation of memory traces in the hippocampus occurs during sharp-wave ripples (SWRs; 140-250 Hz). To better understand the mechanisms underlying high-frequency oscillations and cognitive comorbidities in epilepsy, we evaluated how rigorously identified deep CA1 pyramidal cells (dPCs) discharge during SWRs in control and TLE mice.

However, it is not fully understood how constitutively active CB1 receptors, tonic endocannabinoid signaling, and its regulation by multiple serine hydrolases contribute to the synapse-specific calibration of neurotransmitter release probability. To address this question at perisomatic and dendritic GABAergic synapses in the mouse hippocampus, we used a combination of paired whole-cell patch-clamp recording, liquid chromatography/tandem mass spectrometry, stochastic optical reconstruction microscopy super-resolution imaging, and immunogold electron microscopy.
View Article and Find Full Text PDFAfter birth, stem cells in the subventricular zone (SVZ) generate neuroblasts that migrate along the rostral migratory stream (RMS) to become interneurons in the olfactory bulb (OB). This migration is crucial for the proper integration of newborn neurons in a pre-existing synaptic network and is believed to play a key role in infant human brain development. Many regulators of neuroblast migration have been identified; however, still very little is known about the intracellular molecular mechanisms controlling this process.
