Progressive heterotopic ossification (HO) is a hallmark of fibrodysplasia ossificans progressiva (FOP); however, this tissue transformation is not random. Rather, we noticed that HO in FOP progresses in well-defined but inexplicable spatial and temporal patterns that correlate precisely with infrared thermographs of the human body. FOP is caused by gain-of-function mutations in Activin A receptor type I (ACVR1/ALK2), a bone morphogenetic protein (BMP) type I receptor kinase. As with all enzymes, the activity of ACVR1 is temperature-dependent. We hypothesized that connective tissue progenitor cells that express the common heterozygous ACVR1R206H mutation (FOP CTPCs) exhibit a dysregulated temperature response compared to control CTPCs and that the temperature of FOP CTPCs that initiate and sustain HO at various anatomic sites determines, in part, the anatomic distribution of HO in FOP. We compared BMP pathway signaling at a range of physiologic temperatures in primary CTPCs isolated from FOP patients (n = 3) and unaffected controls (n = 3) and found that BMP pathway signaling and resultant chondrogenesis were amplified in FOP CTPCs compared to control CTPCs (p less then 0.05). We conclude that the anatomic distribution of HO in FOP may be due, in part, to a dyregulated temperature response in FOP CTPCs that reflect anatomic location. While the association of temperature gradients with spatial patterns of HO in FOP does not demonstrate causality, our findings provide a paradigm for the physiologic basis of the anatomic distribution of HO in FOP and unveil a novel therapeutic target that might be exploited for this disabling condition.Osteoarthritis (OA) is a disease associated with a disorder of cholesterol metabolism. Our previous studies showed that prenatal ethanol exposure (PEE) caused cholesterol accumulation in articular cartilage and increased the susceptibility to OA in offspring. However, we did not determine whether pravastatin, a cholesterol-lowering agent, could rescue PEE-induced susceptibility to OA. Here, fetal rats were divided into a PEE group and a control group during pregnancy. At postnatal week (PW) 8, sixteen male offspring rats from both groups were injected papain through the articular cavity. Eight of them from each group were treated with pravastatin (20 mg/kg·d) by gavage for four weeks simultaneously. We found that pravastatin ameliorated papain-induced high expression of inflammatory factors [interleukin (IL)-1, IL-6], matrix degradation enzymes [matrix metalloproteinase (MMP)-3, MMP-13], and apoptosis factors (caspase-3 and caspase-8) in the cartilage of the PEE group. Also, pravastatin significantly reduced the content of TCH in the blood and cartilage of the PEE offspring and improved cholesterol efflux pathway. Our in vitro findings further confirmed that pravastatin partially reversed cholesterol-induced inflammation and apoptosis of chondrocytes. In conclusion, pravastatin effectively reduced inflammation and matrix degradation, and thus ameliorate OA susceptibility in articular cartilage by relieving cholesterol accumulation in chondrocyte.Tibial subchondral bone marrow lesions (BMLs) identified by MRI have been recognised as potential disease predictors in knee osteoarthritis (KOA), and may associate with abnormal bone matrix mineralisation and reduced bone quality. However, these tissue-level changes of BMLs have not been extensively investigated. Thus, the aim of this study was to quantify the degree of subchondral bone matrix mineralisation (both plate and trabeculae) in relation to histomorphometric parameters of bone remodelling and osteocyte lacunae (OL) characteristics in the tibial plateau (TP) of KOA patients with and without BMLs (OA-BML and OA No-BML, respectively) in comparison to nonOA cadaveric controls (CTL). Osteochondral (cartilage-bone) tissue was sampled from the BML signal region within the medial compartment for each OA-BML TP, and from a corresponding medial region for OA No-BML and CTL TPs. The tissue samples were embedded in resin, and sections stained with Von-Kossa Haematoxylin and Eosin (H&E) for quantitation of statther, these findings indicate that tibial BMLs in advanced KOA patients are characterised by significantly hypo-mineralised subchondral bone compared with CTL. These differences associated with evidence of increased bone remodelling in OA-BML, and may influence the mechanical properties of the subchondral bone, with implications for the overlying cartilage.
To evaluate the influences and risk factors for severe bleeding complications during vitreoretinal surgery and to investigate the role of antiplatelet and anticoagulant agents.

Prospective trial.

Patients undergoing vitreoretinal surgery.

The procedures included were pars plana vitrectomy and scleral buckling. AT406 mw We developed a uniform classification to grade the bleeding severity. Bleeding was graded on an ordinal scale ranging from 0 to 5. Immediately after surgery and 1 day later, the incidence and the severity of bleeding events was documented on a standardized form. A grade of 3 or more was defined as severe bleeding. Furthermore, the influence of known systemic disorders before surgery, the type of anesthesia, type of surgical procedure, intraoperative blood pressure, and the use or change of antiplatelet or anticoagulant agents on intraoperative bleeding was analyzed.

Incidence and risk factors for severe intraoperative bleeding events.

Data from 374 eyes undergoing vitreoretinal procedures wed artery stenosis influences the risk of severe intraoperative bleeding events, we did not detect an increased risk related to coexisting antiplatelet or anticoagulant medication use, or both.
Fetal growth restriction has traditionally been defined as fetuses with an estimated fetal weight <10th percentile for gestational age. In 2020, the Society for Maternal-Fetal Medicine recommended that the definition be expanded to include either an estimated fetal weight<10th percentile or a fetal abdominal circumference<10th percentile.

We sought to determine the impact of adding the criterion abdominal circumference<10th percentile on the rate of diagnosis of fetal growth restriction vs using the criterion estimated fetal weight<10th percentile alone. In addition, we evaluated the definition proposed by Copel and Bahtiyar, estimated fetal weight<10th percentile or abdominal circumference<5th percentile.

This was a retrospective, descriptive study from 3 consultative maternal-fetal medicine practices. Biometry was compiled from ultrasound examinations from January 2019 to July 2020. The inclusion criteria were singleton pregnancy, gestational age of ≥24 weeks, presence of fetal cardiac activity, and presence of 4 standard fetal biometry parameters (biparietal diameter, head circumference, abdominal circumference, and femur length).
