Fracture Fusion on Fast-Forward: Locally Administered Deferoxamine Significantly Enhances Fracture Healing in Animal Models: A Systematic Review and Meta-Analysis.

Fractures, with a yearly incidence of 1.2%, can lead to healing complications in up to 10% of cases. The angiogenic stimulant deferoxamine (DFO) is recognized for enhancing bone healing when administered into the fracture gap.

Panitumumab versus cetuximab in combination with irinotecan in refractory metastatic colorectal cancer.

Purpose: There is evidence that adding cetuximab can overcome resistance to irinotecan, but a similar analysis with Panitumumab isn't readily available. This study evaluated the activity of each anti-EGFR plus irinotecan as a salvage third-line treatment for metastatic colorectal cancer.

Methods: This is a retrospective cohort of metastatic colorectal cancer patients who progressed to irinotecan monotherapy and were exposed to an anti-EGFR antibody as a third line of treatment.

Quantitative ultrasound imaging reveals distinct fracture-associated differences in tibial intracortical pore morphology and viscoelastic properties in aged individuals with and without diabetes mellitus - an exploratory study.

Introduction: Diabetes mellitus (DM) is a chronic metabolic disorder that increases fragility fracture risk. Conventional DXA-based areal bone mineral density (aBMD) assessments often underestimate this risk. Cortical Backscatter (CortBS) ultrasound, a radiation-free technique, non-invasively analyzes cortical bone's viscoelastic and microstructural properties.

Antibody Levels from High-Throughput Variant-Specific SARS-CoV-2 Anti-Spike IgG and ACE2 Neutralization Assays Correlate with COVID Infection Risk in a Large Population.

Background: SARS-CoV-2 antibody levels have been proposed as a correlate of protection (CoP) from infection. Yet, large-scale prospective studies of cost-effective scalable antibody measures as predictors of infection under real-world conditions are limited. We examined whether antibody levels measured using high-throughput variant-specific SARS-CoV-2 anti-spike immunoglobulin G (IgG) and ACE2-neutralization assays correlate with cell-based neutralizing antibody (NAb) measurements, and whether they can serve as a reasonable CoP from SARS-CoV-2 infection.

Consumer sleep technology use in individuals with obstructive sleep apnea: does it have a role in monitoring treatment response?

Consumer sleep technology (CST) has an emerging role in monitoring sleep, including screening or surveillance of sleep disorders; however, few data are available on CST in patients with obstructive sleep apnea (OSA). We analyzed attitudes towards CST and patterns of CST use among individuals with OSA. Among 251 respondents (mean age 57.

Emil Kraepelin and Walter Benjamin: distant contemporaries, diverse working methods, any resonance?

The work methods of eminent psychiatrist Emil Kraepelin (1856-1926) and of literary and cultural critic Walter Benjamin (1892-1940) are described based on the literature describing their ways of working. Kraepelin's approach of cross-sectional observation of symptoms and the longitudinal study of illness course in distinguishing 'disease entities' as well as his research strategy of investigating causes and correlates using methods of experimental psychology, pathology and neurobiology are described. Critical statements (on Kraepelin's work) highlighting preconceived concepts, ideological positions and a lack of critical reflection are reported.

What kind of «thing» is mental illness? Listening to Kraepelin, Jaspers and Kronfeld.

Since its beginnings psychiatry controversely debated about the appropriate concept of illness, about nosology and the diagnostic terms and procedures based upon it. This paper discusses the approaches introduced by Emil Kraepelin (1856-1926), Karl Jaspers (1883-1969) and Arthur Kronfeld (1886-1941). Whereas Kraepelin postulated the existence of «natural entities» with regard to mental illness, Jaspers acknowledged the heuristic value of the term «disease entity», but declared it a «regulative idea» in a Kantian sense, i.

International expert consensus statement: surgical failure in obstructive sleep apnea.

Purpose: Upper airway (UA) surgery is commonly employed in the treatment of patients with obstructive sleep apnea (OSA). The intricate pathophysiology of OSA, variability in sites and patterns of UA collapse, and the interaction between anatomical and non-anatomical factors in individual patients may contribute to possible surgical failures. This clinical consensus statement aims to identify areas of agreement among a development group comprising international experts in OSA surgery, regarding the appropriate definition, predictive factors in patients, and management of surgical failure in OSA treatment.

Extracellular Vesicle-Encapsulated microRNAs and Respiratory Health Among American Indian Participants in the Strong Heart Study.

Background: American Indian populations have experienced marked disparities in respiratory disease burden. Extracellular vesicle-encapsulated microRNAs (EV-miRNAs) are a novel class of biomarkers that may improve recognition of lung damage in indigenous populations in the United States.

Research Question: Are plasma EV-miRNAs viable biomarkers of respiratory health in American Indian populations?

Study Design And Methods: The Strong Heart Study is a prospective cohort study that enrolled American Indian patients aged 45 to 74 years.

Dose dense versus 3 weekly AC during neoadjuvant chemoimmunotherapy for triple negative breast cancer.

Neoadjuvant pembrolizumab plus chemotherapy (P + CT) has emerged as a standard of care for stage II-III triple-negative breast cancer (TNBC). However, the best anthracycline-cyclophosphamide (AC) schedule remains to be determined. While the KEYNOTE-522 regimen employs AC every 3 weeks (q3w AC), previous studies have shown overall survival benefits of dose-dense regimens for early-stage breast cancer.

Assessing Competencies, Needs, and Satisfaction With the Transition From Pediatric to Adult Health Care in Rheumatology: Development and Validation of the Transition-KompAZ.

Objective: The aim of this study was to develop and psychometrically validate a self-report instrument to assess (1) competencies, (2) needs, and (3) satisfaction among youth transitioning from pediatric to adult rheumatology.

Methods: The Transition-KompAZ was developed in several steps with conceptual and psychometric analyses. To test its psychometric properties, the instrument was administered to adolescents and young adults (AYAs; 16-25 years) with inflammatory rheumatic diseases before (group 1) or after (group 2) transfer to adult rheumatology.

Anti-TNF therapy impairs both short- and long-term IgG responses after repeated vaccination.

Background: Recently, it has been questioned whether vaccination of patients with inflammatory (auto)immune diseases under anti-tumor necrosis factor (TNF) treatment leads to impaired vaccine-induced immune responses and protection against breakthrough infections. However, the effects of TNF blockade on short- and long-term immune responses after repeated vaccination remain unclear. Vaccination studies have shown that initial short-term IgG antibodies (Abs) carry highly galactosylated and sialylated Fc glycans, whilst long-term IgG Abs have low levels of galactosylation and sialylation and are most likely generated by long-lived plasma cells (PCs) derived primarily from the germinal center (GC) response.

Unplanned Hospital Admissions in Patients With Solid Tumors in Brazil: Causes and Progressive Disease's Impact on Outcomes.

Purpose: Most patients with cancer will be hospitalized throughout the disease course. However, most evidence on the causes and outcomes of these hospitalizations comes from administrative data or small retrospective studies from high-income countries.

Methods: This study is a retrospective cohort of patients with solid tumors hospitalized from February 1, 2021, to December 31, 2021, in a tertiary cancer center in São Paulo, Brazil.

The EV antibody database: An interactive database of curated antibodies for extracellular vesicle and nanoparticle research.

Antibodies are critical tools for research into extracellular vesicles (EVs) and other extracellular nanoparticles (ENPs), where they can be used for their identification, characterization, and isolation. However, the lack of a centralized antibody platform where researchers can share validation results thus minimizing wasted personnel time and reagents, has been a significant obstacle. Moreover, because the performance of antibodies varies among assay types and conditions, detailed information on assay variables and protocols is also of value.

Linguistic and (micro)cultural differences in the global debate about re-naming 'schizophrenia': A mixed-methods survey from Switzerland.

Background And Hypothesis: This survey explores Swiss mental health professionals', users', and relatives' opinions on re-naming schizophrenia exploiting Switzerland's specific multilingualism to examine possible effects of linguistic and microcultural differences on the issue.

Study Design: Opinions on 'schizophrenia' were collected using a self-rated online questionnaire incl. Freetext answers available in the three main Swiss languages, German, French and Italian.

Integrated Genomic and Social Network Analyses of SARS-CoV-2 Transmission in the Healthcare Setting.

Background: Infection prevention (IP) measures are designed to mitigate the transmission of pathogens in healthcare. Using large-scale viral genomic and social network analyses, we determined if IP measures used during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic were adequate in protecting healthcare workers (HCWs) and patients from acquiring SARS-CoV-2.

Methods: We performed retrospective cross-sectional analyses of viral genomics from all available SARS-CoV-2 viral samples collected at UC San Diego Health and social network analysis using the electronic medical record to derive temporospatial overlap of infections among related viromes and supplemented with contact tracing data.

Prognostic Impact of Primary Tumor Sidedness in Stage III Colorectal Cancer: Real-World Evidence from a Brazilian Cohort.

Background: Primary tumor sidedness (PTS) is an independent prognostic factor in patients with metastatic colorectal cancer (CRC), with a worse prognosis for right-sided tumors. There are limited data on the prognostic impact of PTS in stage III CRC. The main objective of this study was to analyze the prognostic impact of PTS in stage III CRC.

Genomic surveillance reveals dynamic shifts in the connectivity of COVID-19 epidemics.

The maturation of genomic surveillance in the past decade has enabled tracking of the emergence and spread of epidemics at an unprecedented level. During the COVID-19 pandemic, for example, genomic data revealed that local epidemics varied considerably in the frequency of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) lineage importation and persistence, likely due to a combination of COVID-19 restrictions and changing connectivity. Here, we show that local COVID-19 epidemics are driven by regional transmission, including across international boundaries, but can become increasingly connected to distant locations following the relaxation of public health interventions.

Long-term outcomes of neoadjuvant immunotherapy plus chemotherapy in patients with early-stage triple-negative breast cancer: an extracted individual patient data and trial-level meta-analysis.

Background: Neoadjuvant immunotherapy (nIO) has emerged as a treatment option for stage II-III triple-negative breast cancer (TNBC). While randomised clinical trials (RCTs) demonstrated pathological complete response rate benefit to nIO added to chemotherapy, additional data on long-term outcomes is warranted. We performed this analysis to evaluate long-term efficacy outcomes of nIO in TNBC.
