Further, mentorship also leads to increased confidence in decision-making, and enhanced work-life balance.

Alcohol, Tobacco, and Marijuana Use Among Individuals Receiving Prescription Opioids for Pain Management.

Objective: Substance use among individuals receiving prescription opioids for pain may be associated with poorer functioning. The purpose of this study was to examine whether the use of substances (ie, alcohol, marijuana, or tobacco) among individuals prescribed opioids for pain management was associated with pain, psychiatric disorders, and opioid misuse.

Methods: Patients with non-cancer pain and a new opioid prescription were recruited from 2 health systems.

A Unique Presentation of Diffuse Intraductal Papillary Mucinous Neoplasm of Bile Duct Successfully Treated With Orthotopic Liver Transplant and Pancreaticoduodenectomy Procedure: A Case Report.

Biliary intraepithelial neoplasm (BilIN) and intraductal papillary mucinous neoplasm of the bile duct (IPMN-B) are recognized as the two main precursors to biliary carcinoma. Surgical resection is the mainstay of treatment, with pancreaticoduodenectomy for extrahepatic biliary duct disease involving the pancreatic or distal portion of the bile duct, and bile duct and liver resection for perihilar and intrahepatic bile duct involvement. For diffuse IPMN-B with involvement of the entirety of the biliary epithelium of both intrahepatic and extrahepatic biliary systems, there is no well-documented consensus on treatment due to its rarity.

Cannabis and Pain Management.

Family physicians are fielding questions about cannabis --particularly for the use of cannabis for treatment of pain. Like about every substance ingested to treat medical conditions, cannabis has risks and benefits. But regarding evidence-based practice and practice-based recommendations for patients about cannabis use, the cart is in front of the horse.

Mechanistic basis of activation and inhibition of protein disulfide isomerase by allosteric antithrombotic compounds.

Background: Protein disulfide isomerase (PDI) is a promising target for combating thrombosis. Extensive research over the past decade has identified numerous PDI-targeting compounds. However, limited information exists regarding how these compounds control PDI activity, which complicates further development.

Everolimus on cystic kidney disease burden reduction in pediatric tuberous sclerosis complex patients: a case series.

Background: Tuberous Sclerosis complex (TSC) is a multisystemic neurocutaneous genetic condition with high rates of morbidity and mortality from subependymal giant cell astrocytoma (SEGA), renal angiomyolipoma, and renal cyst complications. Everolimus is an inhibitor for mTORC1 and is currently used to treat TSC for its main role in rapidly reducing SEGA volume and seizure burden, although mainly studied in the adult population. It has also been shown to stabilize estimated glomerular filtration rate and reduce renal angiomyolipoma size in the adult population.

Comparing neoantigen cancer vaccines and immune checkpoint therapy unveils an effective vaccine and anti-TREM2 macrophage-targeting dual therapy.

The goal of therapeutic cancer vaccines and immune checkpoint therapy (ICT) is to promote T cells with anti-tumor capabilities. Here, we compared mutant neoantigen (neoAg) peptide-based vaccines with ICT in preclinical models. NeoAg vaccines induce the most robust expansion of proliferating and stem-like PD-1TCF-1 neoAg-specific CD8 T cells in tumors.

Contrast enhancement after mechanical thrombectomy: clinical correlations and impact on outcomes.

Purpose: Contrast enhancement (CE) after mechanical thrombectomy (MT) remains a subject of investigation, with a reported prevalence ranging from 31 to 88%. We examined our patients to identify predictors of CE and its impact on outcomes, an aspect that remains understudied.

Methods: We retrospectively analyzed 106 patients who underwent MT at our hospital between 2018 and 2022.

Unilateral Variation of the Left Ascending Pharyngeal Artery: A Case Report.

During routine cadaveric dissection of a 77-year-old male, a series of unique arterial variations were observed within the left anterior cervical region. Firstly, the ascending pharyngeal artery (APA) was observed branching from the common carotid artery (CCA), between the internal (ICA) and external carotid (ECA) arteries. The APA continued superiorly without branching, as is typical for APA.

Chimeras Derived from a P2Y Receptor Antagonist and UDP-Sugar Agonists for Potential Treatment of Inflammation.

Tethered glycoconjugates of a naphthalene- and piperidine-containing antagonist of the P2Y receptor (PPTN) were synthesized, and their nM receptor binding affinity was determined using a fluorescent tracer in hP2YR-expressing whole CHO cells. The rationale for preparing mono- and disaccharide conjugates of the antagonists was to explore the receptor binding site, which we know recognizes a glucose moiety on the native agonist (UDP-glucose), as well as enhance aqueous solubility and pharmacokinetics, including kidney excretion to potentially counteract sterile inflammation. Glycoconjugates with varied linker length, including PEG chains, were compared in hP2YR binding, suggesting that an optimal affinity (IC, nM) in the piperidine series was achieved for triazolyl -linked glucose conjugates having one (, MRS4872, 3.

N-Linked Fucosylated Glycans Are Biomarkers for Prostate Cancer with a Neuroendocrine and Metastatic Phenotype.

Prostate cancer is a heterogeneous disease with a spectrum of pathology and outcomes ranging from indolent to lethal. Although there have been recent advancements in prognostic tissue biomarkers, limitations still exist. We leveraged matrix-assisted laser desorption/ionization imaging of formalin-fixed, paraffin embedded prostate cancer specimens to determine if N-linked glycans expressed in the extracellular matrix of lethal neuroendocrine prostate cancer were also expressed in conventional prostate adenocarcinomas that were associated with poor outcomes.

Memory T-Cells Contribute to Calcium Release from Bones during Lactation in Mice.

Milk production during lactation places a high demand for calcium that is fulfilled both from maternal bone resorption and diet. While it is known that mammary gland-derived PTHrP drives bone resorption during lactation, the impact of postpartum estrogen loss on bone has been unclear. We used a case-control study design to test the effect of estrogen loss in lactating mice.
