Evaluation of HER2-Low breast carcinoma in metastatic settings: a cytological approach to proliferation and survival.

Introduction: Human epidermal growth factor receptor 2 (HER2)-low breast cancer, defined by HER2 immunohistochemistry scores of 1+ or 2+ without gene amplification, represents a unique subgroup with emerging therapeutic implications. Limited data describe the behavior of HER2-low tumors, particularly in metastatic settings. This study evaluated the frequency of HER2-low expression, Ki-67 proliferation index, and survival outcomes across HER2 subtypes in metastatic breast carcinoma using cytology specimens.

Incidentally discovered inflammatory pseudotumour of the spleen: understanding clinical manifestations and diagnosis.

A splenic inflammatory pseudotumour (IPT) is a rare condition in which inflammatory cells and non-cancerous specialised cells known as myofibroblasts abnormally replicate in the spleen. Patients with IPT may experience symptoms like abdominal pain, fever and weight loss, making it difficult to distinguish from processes like cancer. As a result, diagnosing IPT often requires imaging studies and microscopic examination.

Ultrasound-triggered release of vancomycin from a novel spinal device: Antibiotic release and efficacy in vivo.

Post-surgical spinal infection occurs in up to 20% of patients, despite aggressive peri-operative antibiotic treatments. To improve prophylaxis, we have designed and evaluated an ultrasound-activated prophylactic antibiotic release system to combat post-surgical bacterial survival. Polylactic acid (PLA) clips (1 cm) were 3D-printed with an interior reservoir (0.

The long-term effects of housing insecurity in young adulthood on subsequent material hardship, physiological and mental health.

Economic and material hardship, including housing insecurity - limited or uncertain availability or access to safe, quality, and affordable housing - is strongly linked to negative physical and mental health outcomes among adolescents and adults. However, data limitations and the inherent selectivity of housing insecurity have hindered comprehensive analysis of its long-term effects on physiological and mental health. This study uses data from The National Longitudinal Study of Adolescent to Adult Health (Add Health) to construct a sample of participants who experienced housing insecurity between the ages of 18-26 (Wave III) to a suitable control group using propensity score matching.

Retrospective cohort study of trends in the use of outpatient parathyroidectomy by surgical indication.

Background: A shift toward outpatient parathyroidectomy was seen in the early 2000s. Recent trends, especially for secondary and tertiary hyperparathyroidism, have not been described. This study evaluates temporal trends in same-day, overnight, and inpatient parathyroidectomy by surgical indication.

Thyroid Nodules with Indeterminate Cytology and Negative Molecular Profile: Prevalence of Malignancy and Practice Paradigms for Surveillance.

In the era of molecular testing, thyroid nodules with indeterminate cytology are increasingly being managed nonoperatively. The false-negative rates of these molecular tests, and therefore missed malignancies, are not well defined in real-world clinical practice. This retrospective study of patients undergoing fine needle aspiration (FNA) biopsy at our health system between November 2017 and March 2022 included nodules with The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) III and IV cytology and negative, currently negative, or negative but limited ThyroSeq version 3 (TSv3) results.

Hepatosplenic T-cell lymphoma in children and adolescents.

Hepatosplenic T-cell lymphoma (HSTCL) is an aggressive mature T-cell lymphoma characterized by significant hepatosplenomegaly, bone marrow involvement, and minimal or no lymphadenopathy. Primarily affecting young adults, it is exceptionally rare in children and adolescents. This makes diagnosis and treatment particularly challenging for pathologists and pediatric oncologists.

Difficulty With Board Certification in Urology Is Associated With Adverse Medical License Actions.

Introduction: Board certification in urology is a multistep process including a written qualifying examination (QE), followed by an oral certifying examination (CE) approximately 2 years after residency or fellowship completion. The goal of this process is to ensure that urologists are well trained, have an extensive fund of knowledge, demonstrate professionalism and competence in practice, and are safe to practice urology. Board certification in urology serves to both establish and confirm physician competence and ultimately protect the public.

Multidimensional scaling improves distance-based clustering for microbiome data.

Motivation: Clustering patients into subgroups based on their microbial compositions can greatly enhance our understanding of the role of microbes in human health and disease etiology. Distance-based clustering methods, such as partitioning around medoids (PAM), are popular due to their computational efficiency and absence of distributional assumptions. However, the performance of these methods can be suboptimal when true cluster memberships are driven by differences in the abundance of only a few microbes, a situation known as the sparse signal scenario.

Psychometric Evidence and Measurement Invariance by College-Going Status for the Inventory of the Dimensions of Emerging Adulthood (IDEA).

Numerous versions exist of the Inventory of the Dimensions of Emerging Adulthood (IDEA), which is used to assess normative markers of development in the 18-29 age range. However, their comparative psychometric properties have not been adequately explored, and samples including non-college-going emerging adults are rare. In Study 1, confirmatory factor analyses using survey data from 429 college-going and non-college-going emerging adults (52% female, 44% non-white) showed the IDEA-Short Form (IDEA-SF) to be the most psychometrically and conceptually sound version, demonstrating good fit for the five-factor model proposed by Arnett's (2004) theory of emerging adulthood; initial evidence for concurrent validity of the IDEA-SF scores was also presented.

Lineage tracing studies suggest that the placenta is not a de novo source of hematopoietic stem cells.

Definitive hematopoietic stem and progenitor cells (HSPCs) arise from a small number of hemogenic endothelial cells (HECs) within the developing embryo. Understanding the origin and ontogeny of HSPCs is of considerable interest and potential therapeutic value. It has been proposed that the murine placenta contains HECs that differentiate into HSPCs.

Association between chiropractic spinal manipulation for sciatica and opioid-related adverse events: A retrospective cohort study.

Background: Patients receiving chiropractic spinal manipulation (CSM) for spinal pain are less likely to be prescribed opioids, and some evidence suggests that these patients have a lower risk of any type of adverse drug event. We hypothesize that adults receiving CSM for sciatica will have a reduced risk of opioid-related adverse drug events (ORADEs) over a one-year follow-up compared to matched controls not receiving CSM.

Methods: We searched a United States (US) claims-based data resource (Diamond Network, TriNetX, Inc.

Neomorphic leukemia-derived mutations in the TET2 enzyme induce genome instability via a substrate shift from 5-methylcytosine to thymine.

Ten-eleven translocation (TET) enzymes oxidize 5-methylcytosine (mC) in DNA, contributing to the regulation of gene transcription. Diverse mutations of TET2 are frequently found in various blood cancers, yet the full scope of their functional consequences has been unexplored. Here, we report that a subset of TET2 mutations identified in leukemia patients alter the substrate specificity of TET2 from acting on mC to thymine.

Flight phenology and influence of region and habitat on the abundance of Xylosandrus germanus and Anisandrus maiche (Coleoptera: Curculionidae: Scolytinae) in New York.

The non-native wood-boring and symbiotic fungus-culturing Xylosandrus germanus (Blandford) was first reported in New York apple orchards in 2013. Trapping surveys have been conducted annually since to assist growers in timely applications of preventative control measures. In 2021, a similar-looking introduced species, Anisandrus maiche (Kurentsov), was identified in traps in west central New York.

The divergent reactivity of β-diketiminato aluminium hydrides with organophosphoryl compounds.

The reactions of LAlH (L = HC(CMeNAr), Ar = 2,6-PrCH) (1) with diphenylphosphane oxide [PhP(O)H], diphenylphosphinamide [PhP(O)NH], and diaryl/alkyl phosphane [(RO)P(O)H (R = Ph, or Pr)] afford their corresponding compounds with compositions LAl(H)OP(Ph) (2), LAl[OP(Ph)] (3), LAl{[N(H)P(O)(Ph)][OP(Ph)]} (4), LAl(OPr) (5), and LAl(OPh) (6), respectively. These reactions probably undergo a process of dehydrogenation coupling, deaminating dehydrogenation coupling, or chain-breaking coupling. It is noteworthy to mention that the reaction of compound 1 with 2 equiv.

Severe Maternal Morbidity Associated With Chronic Hypertension, Preeclampsia, and Gestational Hypertension.

Importance: Chronic hypertension and preeclampsia are leading risk enhancers for maternal-neonatal morbidity and mortality. Severe maternal morbidity (SMM) indicators include heart, kidney, and liver disease, but studies have not excluded patients with preexisting diseases that define SMM. Thus, SMM risks for uncomplicated chronic hypertension specific to preeclampsia remain unclear.

Topical review: family psychosocial risk screening and social determinants of health assessment.

Objective: Social-ecological factors are highly congruent with social determinants of health (SDOH): Economic Stability; Educational Access/Quality; Healthcare Access/Quality; Neighborhood/Built Environment; and Social/Community Context. In this topical review, the correspondence of social-ecological theory with SDOH and assessment approaches is reviewed. The Psychosocial Assessment Tool (PAT) is used to show how existing tools may facilitate SDOH screening.

Characterizing Conical Intersections of Nucleobases on Quantum Computers.

Hybrid quantum-classical computing algorithms offer significant potential for accelerating the calculation of the electronic structure of strongly correlated molecules. In this work, we present the first quantum simulation of conical intersections (CIs) in a biomolecule, cytosine, using a superconducting quantum computer. We apply the contracted quantum eigensolver (CQE)─with comparisons to conventional variational quantum deflation (VQD)─to compute the near-degenerate ground and excited states associated with the conical intersection, a key feature governing the photostability of DNA and RNA.

Restoring ceftolozane susceptibility: a role for diazabicyclooctane β-lactamase inhibitors?

Paired baseline and post-exposure isolates from 34 patients who developed ceftolozane-tazobactam (TOL-TAZ) resistance following treatment of multidrug-resistant (MDR) infections were analyzed to determine if ceftolozane with an alternative β-lactamase inhibitor could restore susceptibility. The median baseline TOL-TAZ MIC was 2 mg/L; 88% of post-exposure isolates harbored new mutations. Median MIC fold-increase from baseline was 32-, 24-, 16-, and 6-fold for ceftolozane-tazobactam, ceftolozane-avibactam (AVI), ceftolozane-relebactam (REL), and ceftolozane-durlobactam (DUR), respectively.
