Cushing syndrome.

Cushing syndrome (CS) is a constellation of signs and symptoms caused by excessive exposure to exogenous or endogenous glucocorticoid hormones. Endogenous CS is caused by increased cortisol production by one or both adrenal glands (adrenal CS) or by elevated adrenocorticotropic hormone (ACTH) secretion from a pituitary tumour (Cushing disease (CD)) or non-pituitary tumour (ectopic ACTH secretion), which stimulates excessive cortisol production. CS is associated with severe multisystem morbidity, including impaired cardiovascular and metabolic function, infections and neuropsychiatric disorders, which notably reduce quality of life.

Altered olfactory responses in Fmr1 KO mice.

Fragile X syndrome (FXS) is a neurodevelopmental disorder oftentimes associated with abnormal social behaviors and altered sensory responsiveness. It is hypothesized that the inappropriate filtering of sensory stimuli, including olfaction, can lead to aberrant social behavior in FXS. However, previous studies investigating olfaction in animal models of FXS have shown inconsistent results.

Individual-specific strategies inform category learning.

Categorization is an essential task for sensory perception. Individuals learn category labels using a variety of strategies to ensure that sensory signals, such as sounds or images, can be assigned to proper categories. Categories are often learned on the basis of extreme examples, and the boundary between categories can differ among individuals.

Characterizing safety, toxicity, and breast cancer risk reduction using a long-term fulvestrant eluting implant.

For individuals at high risk of developing breast cancer, interventions to mitigate this risk include surgical removal of their breasts and ovaries or five years treatment with the anti-estrogen tamoxifen or aromatase inhibitors. We hypothesized that a silicone based anti-estrogen-eluting implant placed within the breast would provide the risk reduction benefit of hormonal therapy, but without the adverse effects that limit compliance. To this end, we demonstrate that when placed adjacent to mammary tissue in the 7,12-dimethylbenz[a]anthracene-induced rat breast cancer model a fulvestrant-eluting implant delays breast cancer with minimal systemic exposure.

Skeletal abnormalities caused by a Connexin43 mutation in a mouse model for autosomal recessive craniometaphyseal dysplasia.

Craniometaphyseal dysplasia (CMD), a rare craniotubular disorder, occurs in an autosomal dominant (AD) or autosomal recessive (AR) form. CMD is characterized by hyperostosis of craniofacial bones and metaphyseal flaring of long bones. Many patients with CMD suffer from neurological symptoms.

A review of the environmental spread of Salmonella enterica serovars through water in Africa.

Salmonella is an enteric pathogenic bacterium in mammals that thrives in sewage, soil, and aquatic environments because of its wide ecological adaptability. The spread of Salmonella infection is associated with a lack of clean water, poor hygiene, and poor sanitation in developing countries. However, the input of Salmonella-contaminated surface water and groundwater in the environmental dissemination of antimicrobial-resistant Salmonella is obscure outside developed countries.

Physical activity, cathepsin B, and cognitive health.

Regular physical activity (PA) is beneficial for cognitive health, and cathepsin B (CTSB) - a protease released by skeletal muscle during PA - acts as a potential molecular mediator of this association. PA-induced metabolic and mechanical stress appears to increase plasma/serum CTSB levels. CTSB facilitates neurogenesis and synaptic plasticity in brain regions (e.

Heterogeneity of the Treatment Effect with PARP Inhibitors in Metastatic Castration-resistant Prostate Cancer: A Living Interactive Systematic Review and Meta-analysis.

Background And Objective: Selection of patients harboring mutations in homologous recombination repair (HRR) genes for treatment with a PARP inhibitor (PARPi) is challenging in metastatic castration-resistant prostate cancer (mCRPC). To gain further insight, we quantitatively assessed the differential efficacy of PARPi therapy among patients with mCRPC and different HRR gene mutations.

Methods: This living meta-analysis (LMA) was conducted using the Living Interactive Evidence synthesis framework.

Prevalence, Diagnosis, and Management of Stress Urinary Incontinence in Women: A Collaborative Review.

Background And Objective: Stress urinary incontinence (SUI), defined as any involuntary leakage of urine associated with physical activity, remains underdiagnosed and undertreated. This review aims to provide an updated overview of the prevalence, diagnosis, and treatment of SUI in women, drawing upon recent evidence-based literature and clinical guidelines.

Methods: A systematic search of the MEDLINE database was conducted to identify only the most up-to-date and relevant studies published up to February 26, 2024, including the reference ESTER systematic review.

Incidence and Outcomes of Secondary Bladder Cancer Following Radiation Therapy for Prostate Cancer: A Systematic Review and Meta-analysis.

Background And Objective: There is an established association between secondary bladder cancers (SBCs) and radiotherapy (RT) for prostate cancer (PC), which remains a significant concern. Our aim was to update the evidence on SBC incidence across different RT modalities and to compare oncological outcomes for patients diagnosed with SBC to those diagnosed with primary bladder cancer (PBC).

Methods: We searched MEDLINE, Scopus, and Web of Science for studies on SBC following PC.

Should digoxin immune fab be administered based solely on reported ingested amount in acute digoxin poisoning?

Acute digoxin poisoning is increasingly uncommon in emergency medicine. Furthermore, controversy exists regarding indications for antidotal digoxin immune fab in acute poisoning. In healthy adults, the fab prescribing information recommends administration based on "known consumption of fatal doses of digoxin: ≥10mg," while many emergency medicine textbooks suggest fab administration be driven by clinical features or potassium concentration.

C. neoformans meningitis without pleocytosis, hyperproteinorrachia, and hypoglycorrhachia on cerebrospinal fluid studies.

Diagnosis of cryptococcal meningitis is typically aided through CSF analysis obtained via lumbar puncture (LP), revealing elevated WBCs, increased protein, decreased glucose, and increased opening pressure. While CSF culture confirms the diagnosis, it takes days, prompting reliance on these adjuncts. AIDS from Human Immunodeficiency Virus is less commonly diagnosed in the emergency setting due to advances in testing and treatment.

Erector spinae plane block for management of acute opioid withdrawal in the emergency department: A case report.

Background: Gastrointestinal symptoms of acute opioid withdrawal are distressing for patients and are often difficult to manage with conventional therapies. Insufficiently managed opioid withdrawal symptoms may lead patients to leave against medical advice, which can increase their risk of relapse and result in poor outcomes from untreated conditions. We assessed the impact of an erector spinae plane block on the acute gastrointestinal symptoms of opioid withdrawal.

Making sense of vertebrate senses from a neural crest and cranial placode evo-devo perspective.

The evolution of vertebrates from protochordate ancestors marked the beginning of the gradual transition to predatory lifestyles. Enabled by the acquisition of multipotent neural crest and cranial placode cell populations, vertebrates developed an elaborate peripheral nervous system, equipped with paired sense organs, which aided in adaptive behaviors and ultimately, successful colonization of diverse environmental niches. Underpinning the enduring success of vertebrates is the highly adaptable nature of the peripheral nervous system, which is enabled by the exceptional malleability of the neural crest and placode developmental programs.

Coordinating the energetic strategy of glia and neurons for memory.

Memory consolidation requires rapid energy supply to neurons. In a recent study, Francés et al. revealed the signal by which a neuron commands glia to limit fatty acid synthesis in favor of metabolite export during memory formation in Drosophila melanogaster.
