Radiological Diagnosis and Advances in Imaging of Vertebral Compression Fractures.

Vertebral compression fractures (VCFs) affect 1.4 million patients every year, especially among the globally aging population, leading to increased morbidity and mortality. Often characterized with symptoms of sudden onset back pain, decreased vertebral height, progressive kyphosis, and limited mobility, VCFs can significantly impact a patient's quality of life and are a significant public health concern.

Silicone on the Move: Migratory Siliconoma After Retinal Surgery Report of a Case and Review of the Literature.

Silicone granulomas, or "siliconomas," are the common foreign-body inflammatory responses to injected silicone material. In rare cases, siliconomas develop remotely from the original site of injection, secondary to silicone migration. If a history of silicone injection is not noted, such lesions risk misdiagnosis (possibly as infection or malignancy).

Dynamics of leaching of POPs and additives from plastic in a Procellariiform gastric model: Diet- and polymer-dependent effects and implications for long-term exposure.

Procellariiform seabirds are known to have high rates of plastic ingestion. We investigated the bioaccessibility of plastic-associated chemicals [plastic additives and sorbed persistent organic pollutants (POPs)] leached from plastic over time using an in vitro Procellariiform gastric model. High-density polyethylene (HDPE) and polyvinyl chloride (PVC), commonly ingested by Procellariiform seabirds, were manufactured with one additive [decabrominated diphenyl ether (PBDE-209) or bisphenol S (BPS)].

Impact of Deep Learning Image Reconstruction Methods on MRI Throughput.

Purpose To evaluate the effect of implementing two distinct commercially available deep learning reconstruction (DLR) algorithms on the efficiency of MRI examinations conducted in real clinical practice within an outpatient setting at a large, multicenter institution. Materials and Methods This retrospective study included 7346 examinations from 10 clinical MRI scanners analyzed during the pre- and postimplementation periods of DLR methods. Two different types of DLR methods, namely Digital Imaging and Communications in Medicine (DICOM)-based and k-space-based methods, were implemented in half of the scanners (three DICOM-based and two k-space-based), while the remaining five scanners had no DLR method implemented.

Hemibody Irradiation for Bone Metastases: A Systematic Review and Meta-Analysis.

Hemibody irradiation (HBI) is a radiation therapy technique that involves treating one-half of the patient's skeletal system in a single radiation field. It is mostly given as upper hemibody irradiation (UHBI), lower hemibody irradiation (LHBI), or sequential UHBI and LHBI. It is used to treat extensive bone metastases from solid tumors.

Post-migration stress, quality of life, and mental health among accompanied and unaccompanied young refugees in Germany: How do adolescents feel after fleeing?

This study examines the impact of post-migration living difficulties (PMLDs) and quality of life (QoL) on the mental health of 55 young refugees who arrived in Germany either accompanied or unaccompanied. The results reveal that nearly 62% of the participants exhibited clinically significant symptoms of depression or post-traumatic stress disorder. Regression analyses indicate that psychopathology was associated with being unaccompanied and experiencing lower QoL, while QoL was associated with higher economic status and lower PMLDs.

Prospective monitoring of adverse events following vaccination with Modified vaccinia Ankara - Bavarian Nordic (MVA-BN) administered to a Canadian population at risk of Mpox: A Canadian Immunization Research Network study.

MVA-BN is an orthopoxvirus vaccine that provides protection against both smallpox and mpox. In June 2022, Canada launched a publicly-funded vaccination campaign to offer MVA-BN to at-risk populations including men who have sex with men (MSM) and sex workers. The safety of MVA-BN has not been assessed in this context.

Preparing for Mpox Resurgence: Surveillance Lessons From Outbreaks in Toronto, Canada.

Background: With many global jurisdictions, Toronto, Canada, experienced an mpox outbreak in spring/summer 2022. Cases declined following implementation of a large vaccination campaign. A surge in early 2023 led to speculation that asymptomatic and/or undetected local transmission was occurring in the city.

Pre-Post Cannabis Legalization for Adult Use: A Trend Study of Two Cohorts of Young Adult Cannabis Users in Los Angeles.

Cannabis was legalized for adult use in California in 2016 for individuals 21 and older. Among 18-20-years-olds, who can possess cannabis legally as medical cannabis patients (MCP) but not as non-patient cannabis users (NPU), the impact of adult use legalization (AUL) on cannabis and other substance use is unknown. Two cohorts of 18-20-year-old cannabis users (MCP and NPU) were surveyed, one in 2014-15 ( = 172 "pre-AUL") and another in 2019-20 ( = 139 "post-AUL"), using similar data collection methods in Los Angeles, California.

Stain-Free Sperm Analysis and Selection for Intracytoplasmic Sperm Injection Complying with WHO Strict Normal Criteria.

This multi-center study evaluated a novel microscope system capable of quantitative phase microscopy (QPM) for label-free sperm-cell selection for intracytoplasmic sperm injection (ICSI). Seventy-three patients were enrolled in four in vitro fertilization (IVF) units, where senior embryologists were asked to select 11 apparently normal and 11 overtly abnormal sperm cells, in accordance with current clinical practice, using a micromanipulator and 60× bright field microscopy. Following sperm selection and imaging via QPM, the individual sperm cell was chemically stained per World Health Organization (WHO) 2021 protocols and imaged via bright field microscopy for subsequent manual measurements by embryologists who were blinded to the QPM measurements.

Holton et al., Characterization of asbestos exposures associated with the use of facial makeups. Risk Analysis, 42, 2129-2139.

Holton and colleagues have performed a risk assessment after measuring asbestos released from several samples of facial makeup. Unfortunately, it is not possible to interpret or generalize their findings because the authors have not described the source(s) of the talc tested or the asbestos concentrations of the samples. The concentration of amphiboles varies widely between sources, and the authors are urged to divulge the locations of the ore bodies providing the talc for their samples, as well as the asbestos concentration of the samples, so that the results may be interpreted and possibly generalized.

Microplastic in northern anchovies (Engraulis mordax) and common murres (Uria aalge) from the Monterey Bay, California USA - Insights into prevalence, composition, and estrogenic activity.

Microplastic (particle size <5 mm) is considered an emerging threat to the marine environment, yet data are limited for coastal ecosystems.

Analysis of two cooperating antibodies unveils immune pressure imposed on HIV Env to elicit a V3-glycan supersite broadly neutralizing antibody lineage.

Elicitation of broadly neutralizing antibodies (bnAbs) is a goal of vaccine design as a strategy for targeting highly divergent strains of HIV-1. Current HIV-1 vaccine design efforts seek to elicit bnAbs by first eliciting their precursors through prime-boost regimens. This requires an understanding of the co-evolution between viruses and antibodies.

Gemtuzumab Ozogamicin Treatment Results in Decreased Proliferation and Differentiation of Human Megakaryocytes but Does Not Inhibit Mature Platelet Function.

Mylotarg (Gemtuzumab ozogamicin [GO]), an antibody drug conjugate comprising a CD33-directed antibody linked to calicheamicin, is approved for use in certain acute myeloid leukemia patients. Following reports of prolonged thrombocytopenia and hemorrhagic events in a subset of patients, a detailed series of in vitro and ex vivo studies was performed at the request of regulators, both to look at the effects of GO on platelet production and to determine whether treatment with GO was likely to affect platelet aggregation under a variety of conditions. Treatment with GO resulted in cellular cytotoxicity and/or decreased differentiation during human megakaryocyte development.

Comparative Analyses of Poly(ADP-Ribose) Polymerase Inhibitors.

Poly(ADP-ribose) polymerase inhibitors (PARPi) are approved as monotherapies in -mutated (m) metastatic breast and ovarian cancers, and in advanced pancreatic and metastatic castration-resistant prostate cancers. Differential safety profiles across PARPi necessitate improved mechanistic understanding of inhibitor differences, especially with expansion of PARPi indications and drug combinations. Here, we report in vitro evaluations of PARPi (-/+ PARP trapper temozolomide, TMZ) with reference to total clinical mean concentration average or maximum (tC, tC), to elucidate contributions of primary pharmacology and structural differences to clinical efficacy and safety.
