Purpose
The study aims to evaluate the risk factors and incidence of thromboembolic events among adult women with cancer who underwent controlled ovarian hyperstimulation (COH) for fertility ...preservation.
Methods
Retrospective, descriptive cohort analysis of patient demographics, medical history, cancer type/treatment, laboratory values, thrombosis within 6 months of COH.
Results
4 of 127 study participants experienced a venous thromboembolic event within 6 months of COH. The median time between oocyte aspiration and the event was 0.25 years (range = 0.10–0.50). The average age at time of event was 25.3 years (SD = 5.3). Three of four thrombotic patients had ovarian cancer, one had breast cancer. All had received surgery and chemotherapy for treatment. All underwent an antagonist cycle ovarian stimulation protocol — none developed ovarian hyperstimulation syndrome. The average anti-mullerian hormone level at the time of hyperstimulation in the thrombosis group was 1.6 (SD = 1.3), compared to 3.6 in the non-thrombosis group. The average max estradiol level reached during ovarian stimulation was 1281.3 (SD = 665.3) in the thrombosis group and 1839.1 (SD = 1513.9) in the non-thrombosis group. Thromboembolic events were not directly associated with mortality.
Conclusions
Within this small descriptive study, the incidence of thromboembolic events in women with cancer undergoing COH for fertility preservation is high. Cancer may play a greater role than COH in thrombosis risk. Ovarian cancer patients who undergo ovarian stimulation may have an increased risk compared to other cancer types. These findings may inform future, prospective studies to determine the role of thromboprophylaxis.

Oxidative stress has been implicated in the pathogenesis of osteoarthritis and has become an important therapeutic target. Investigations of various antioxidant supplements, reactive oxidative ...species (ROS) pathway mediators, and free radical scavengers for treating osteoarthritis have demonstrated common disadvantages including poor bioavailability and stability, as well as rapid joint clearance or release profiles from delivery vehicles. Moreover, these therapies do not target cartilage, which irreversibly degenerates in the presence of oxidative stress. The goal of this study was to engineer a nanoparticle system capable of sustained retention in the joint space, localization to cartilage, and mitigation of oxidative stress. Towards this goal, ROS scavenging manganese dioxide nanoparticles with physicochemical properties (less than 20 nm and cationic) that facilitate their uptake into cartilage were developed and characterized. These particles penetrated through the depth of cartilage explants and were found both in the extracellular matrix as well as intracellularly within the resident chondrocytes. Furthermore, the particles demonstrated chondroprotection of cytokine-challenged cartilage explants by reducing the loss of glycosaminoglycans and release of nitric oxide. Quantitative PCR analysis revealed that the particles mitigated impacts of oxidative stress related genes in cytokine-challenged chondrocytes. When injected intra-articularly into rats, the particles persisted in the joint space over one week, with 75% of the initial signal remaining in the joint. Biodistribution and histological analysis revealed accumulation of particles at the chondral surfaces and colocalization of the particles with the lacunae of chondrocytes. The results suggest that the manganese dioxide nanoparticles could be a promising approach for the chondroprotection of osteoarthritic cartilage.

Development of organoids and microfluidic on-chip models has enabled studies of organ-level disease pathophysiologies
in vitro
. However, current lung-on-a-chip platforms are primarily monolayer ...epithelial-endothelial co-cultures, separated by a thin membrane, lacking microvasculature-networks or interstitial-fibroblasts. Here we report the design, microfabrication, and characterization of a unique microphysiological on-chip device that recapitulates the human lung interstitium-airway interface through a 3D vascular network, and normal or diseased fibroblasts encapsulated within a fibrin-collagen hydrogel underneath an airlifted airway epithelium. By incorporating fibroblasts from donors with idiopathic pulmonary fibrosis (IPF), or healthy-donor fibroblasts treated with TGF-β1, we successfully created a fibrotic, alpha smooth muscle actin (αSMA)-positive disease phenotype which led to fibrosis-like transformation in club cells and ciliated cells in the airway. Using this device platform, we further modeled the cystic fibrosis (CF) epithelium and recruitment of neutrophils to the vascular networks. Our results suggest that this microphysiological model of the human lung could enable more pathophysiologically relevant studies of complex pulmonary diseases.

INTRODUCTION:
Perinatal mental illness imparts a significant health burden. A multitude of factors are hypothesized to increase the incidence of perinatal mood and anxiety disorders (PMADs) in the ...fetal surgical population, including uncertain fetal prognosis and the inherent risks of surgery and preterm delivery. We sought to determine the disease course of PMADs in the fetal surgery population.
METHODS:
A retrospective chart review was conducted of fetal surgery patients from 2017 to 2021 at a tertiary care center. Demographics, surgical, obstetric, and psychiatric diagnoses were recorded. Standard descriptive analyses were performed.
RESULTS:
One hundred nineteen eligible patients were identified. Fetal surgery was performed at a median gestational age of 23.0 (range 16.0–34.0) weeks. Laser ablation of placental anastomoses (n=51) and in utero myelomeningocele repair (n=22) were the most common procedures. 26.8% (32/119) had preexisting mood disorders, with 59.3% (19/32) and 53.1% (17/32) on a baseline medication for depression or anxiety, respectively, prior to surgery. 26.4% (23/87) of patients without a history of anxiety or depression had a new diagnosis of PMAD. Two patients experienced suicidal ideation. 6.7% (8/119) and 10.1% (12/119) initiated a new psychiatric medication during or post-pregnancy, respectively. 19.8% (21/113) received a therapy referral. Among patients with baseline anxiety or depression, 62.5% (20/32) experienced an exacerbation postpartum with 25.0% (8/32) referred for therapy, and 34.3% (11/32) changing dose or medication for anxiety and 37.5% (12/32) for depression.
CONCLUSION:
Among patients undergoing fetal surgery, a high incidence of PMAD was identified. Most patients with prepregnancy anxiety or depression experienced an exacerbation postpartum. Further research into effective supportive interventions is warranted.
Perinatal mental illness presents a significant health burden to both patients and families. Many factors are hypothesized to increase the incidence of perinatal depression and anxiety in the fetal ...surgical population, including uncertain fetal prognosis and inherent risks of surgery and preterm delivery.
This study aimed to determine the incidence and disease course of postpartum depression and anxiety in the fetal surgery population.
A retrospective medical record review study was conducted of fetal surgery patients delivering between November 2016 and November 2021 at an academic level IV perinatal healthcare center. Demographics and surgical, obstetrical, and psychiatric diagnoses were abstracted. Standard descriptive analyses were performed.
Eligible patients were identified (N=119). Fetal surgery was performed at a mean gestational age of 22.8 weeks (standard deviation, 4.11). Laser ablation of placental anastomoses (n=51) and in utero myelomeningocele repair (n=22) were the most common procedures. Of 119 patients, 34 (28.6%) were diagnosed with preexisting depression or anxiety, with 19 (55.9%) and 17 (50.0%) on baseline medication for depression or anxiety, respectively, before surgery. Of 85 patients, 23 (27.1%) without a history of anxiety or depression had new identification of one or both after delivery. Of note, 2 patients experienced suicidal ideation after delivery. Of the 119 patients, 8 (6.7%) and 12 (10.1%) initiated a new psychiatric medication during or after pregnancy, respectively, and 19 (16.0%) received a therapy referral. Among patients with baseline anxiety or depression, 20 of 34 patients (58.8%) experienced an exacerbation after delivery, 9 of 34 patients (26.5%) were referred for therapy, 9 of 34 patients (26.5%) were changing dose or medication for anxiety, and 11 of 34 patients (32.4%) were changing dose or medication for depression. Of the 119 patients, 24 (20.2%) experienced new or worsening depression or anxiety after the standard 6-week postpartum visit.
Among patients undergoing fetal surgery, a high incidence of postpartum depression and anxiety was identified, with most patients with prepregnancy anxiety or depression experiencing exacerbation after delivery. The timeframe to clinical presentation with depression or anxiety symptoms may be delayed beyond the traditional 6-week postpartum period and into the first postpartum year. This observation could be attributed to de novo postpartum exacerbation or a lack of standardized treatment approaches earlier in the disease course or antepartum period. Understanding effective longitudinal supportive interventions is an essential next step.
