A moderate spinal contusion injury in rats alters bone turnover both below and above the level of injury with sex-based differences apparent in long-term recovery.

Spinal cord injury (SCI) leads to significant sublesional bone loss and high fracture rates. While loss of mechanical loading plays a significant role in SCI-induced bone loss, animal studies have demonstrated mechanical loading alone does not fully account for loss of bone following SCI. Indeed, we have shown that bone loss occurs below the level of an incomplete moderate contusion SCI, despite the resumption of weight-bearing and stepping.

Neonatal Survivability following Previable PPROM after Hospital Readmission for Intervention.

 To describe our hospital's experience following expectant management of previable preterm prelabor rupture of membranes (pPPROM).  Retrospective review of neonatal survival and maternal and neonatal outcomes of pPPROM cases between 2012 and 2019 at a tertiary referral center in South Central Louisiana. Regression analyses were performed to identify predictors of neonatal survival.

Technetium immobilization by materials through sorption and redox-driven processes: A literature review.

The objective of this review is to evaluate materials for use as a barrier or other deployed technology to treat technetium-99 (Tc) in the subsurface. To achieve this, Tc interactions with different materials are considered within the context of remediation strategies. Several naturally occurring materials are considered for Tc immobilization, including iron oxides and low solubility sulfide phases.

Iodine immobilization by materials through sorption and redox-driven processes: A literature review.

Radioiodine-129 (I) in the subsurface is mobile and limited information is available on treatment technologies. Scientific literature was reviewed to compile information on materials that could potentially be used to immobilize I through sorption and redox-driven processes, with an emphasis on ex-situ processes. Candidate materials to immobilize I include iron minerals, sulfur-based materials, silver-based materials, bismuth-based materials, ion exchange resins, activated carbon, modified clays, and tailored materials (metal organic frameworks (MOFS), layered double hydroxides (LDHs) and aerogels).

Evaluation of materials for iodine and technetium immobilization through sorption and redox-driven processes.

Radioactive iodine-129 (I) and technetium-99 (Tc) pose a risk to groundwater due to their long half-lives, toxicity, and high environmental mobility. Based on literature reviewed in Moore et al. (2019) and Pearce et al.

Visualization of rapid electron precipitation via chorus element wave-particle interactions.

Chorus waves, among the most intense electromagnetic emissions in the Earth's magnetosphere, magnetized planets, and laboratory plasmas, play an important role in the acceleration and loss of energetic electrons in the plasma universe through resonant interactions with electrons. However, the spatial evolution of the electron resonant interactions with electromagnetic waves remains poorly understood owing to imaging difficulties. Here we provide a compelling visualization of chorus element wave-particle interactions in the Earth's magnetosphere.

Hemorrhagic Stroke Resulting From Venous Malformation at 20 Weeks of Pregnancy.

Background: Stroke in the pregnant patient is not a common occurrence. Despite its relative rarity, stroke during pregnancy is associated with high morbidity and mortality for both mother and infant. We report the case of a patient who experienced a hemorrhagic stroke during pregnancy because of venous cavernoma.

Obstetrical Outcomes of Ultrasound Identified Uterine Fibroids in Pregnancy.

Objective We aimed to determine if fibroids in pregnancy, categorized by size, are associated with adverse obstetrical outcomes. Study Design Demographic, clinical, and delivery data were collected from charts of women with singleton gestations who delivered at >20 weeks gestation with fibroids identified at routine anatomy scan and their randomly selected age-matched controls. Largest fibroid diameter was used to categorize small fibroids (≤5 cm) and large fibroids (>5 cm).

Selenite sorption by carbonate substituted apatite.

The sorption of selenite, SeO, by carbonate substituted hydroxylapatite was investigated using batch kinetic and equilibrium experiments. The carbonate substituted hydroxylapatite was prepared by a precipitation method and characterized by SEM, XRD, FT-IR, TGA, BET and solubility measurements. The material is poorly crystalline, contains approximately 9.

Gastrointestinal Conditions during Pregnancy.

Pregnancy causes anatomic and physiologic changes in the gastrointestinal tract. Pregnant women with intestinal disease such as Crohn disease or ulcerative colitis pose a management challenge in clinical diagnosis, radiologic evaluation, and treatment secondary to potential risk to the fetus. Heightened physician awareness on possible etiologies such as appendicitis, diverticulitis, and rarely colorectal cancer is required for rapid diagnosis and treatment to improve maternal/fetal outcome.

Lymphocytic myocarditis presenting as nausea, vomiting, and hepatic dysfunction in the first trimester of pregnancy.

Background: Lymphocytic myocarditis, an immune disorder of left ventricular dysfunction with sometimes confounding clinical presentations, occurs rarely during pregnancy.

Case: At 12 weeks gestation, a multigravid patient presented with a 2-month history of nausea and vomiting. Other symptomatology included postprandial epigastric pain, loose stools, and a 10-lb (4.
