BACKGROUND: The Phase 1 CLOVER study (NCT03509012) assessed durvalumab in combination with concurrent chemoradiotherapy (cCRT) in patients with advanced solid tumors; we report results from the head and neck squamous cell carcinoma (HNSCC) cohort. METHODS: Patients with histologically/cytologically confirmed locally advanced HNSCC, eligible for definitive cCRT and not considered for primary surgery, received durvalumab plus cisplatin and concurrent external beam radiation...

Liquid crystalline elastomers (LCEs) are stimuli-responsive materials that transduce an input energy into a mechanical response. LCE composites prepared with photothermal agents, such as nanoinclusions, are a means to realize wireless, remote, and local control of deformation with light. Amongst photothermal agents, gold nanorods (AuNRs) are highly efficient converters when the irradiation wavelength matches the longitudinal surface plasmon resonance (LSPR) of the AuNRs. However, AuNR aggregation broadens the LSPR which also reduces photothermal efficiency...

INTRODUCTION: For patients with unresectable, stage III non-small-cell lung cancer (NSCLC), current standard of care is concurrent chemoradiotherapy (cCRT) followed by consolidation durvalumab. However, earlier initiation of durvalumab simultaneously with cCRT may increase antitumor activity relative to initiation after cCRT. The phase 1 CLOVER study (NCT03509012) evaluated durvalumab combined with cCRT in patients with advanced solid tumors; we report findings from the NSCLC cohort. METHODS: CLOVER comprised a dose-limiting toxicity (DLT) assessment part, followed by an expansion part...

OBJECTIVES: Interpretations of the primate and human fossil record often rely on the estimation of somatic dimensions from bony measures. Both somatic and skeletal variation have been used to assess how primates respond to environmental change. However, it is unclear how well skeletal variation matches and predicts soft tissue. Here, we empirically test the relationship between tissues by comparing somatic and skeletal measures using paired measures of pre- and post-mortem rhesus macaques from Cayo Santiago, Puerto Rico...

OBJECTIVES: Estimation of body mass from skeletal metrics can reveal important insights into the paleobiology of archeological or fossil remains. The standard approach constructs predictive equations from postcrania, but studies have questioned the reliability of traditional measures. Here, we examine several skeletal features to assess their accuracy in predicting body mass. MATERIALS AND METHODS: Antemortem mass measurements were compared with common skeletal dimensions from the same animals postmortem, using 115 rhesus macaques (male: n = 43; female: n = 72)...

BACKGROUND: Scientific investigation of how to sustain the implementation of evidence-based interventions (EBI) is emerging. Sustaining the implementation of EBIs helps ensure their effects on improving health endure. External policy or practice agencies, such as government health departments, are often tasked with supporting individual organisations with sustaining their delivery of EBIs, for example, through financing, training or the provision of other supports. However, to our knowledge, the approaches taken by policy and practice agencies to support the sustainment of EBIs have not been consolidated, categorised and described as a typology...

PURPOSE: The capacity for machine learning (ML) to facilitate radiotherapy (RT) planning for primary brain tumors has not been described. We evaluated ML-assisted RT planning with regards to clinical acceptability, dosimetric outcomes and planning efficiency for adults and children with primary brain tumours. METHODS AND MATERIALS: In this prospective study, children and adults receiving 54 Gy fractionated radiotherapy for a primary brain tumor were enrolled. For each patient, one ML-assisted RT plan was created and compared with one or two plans created using standard ("manual") planning procedures...

INTRODUCTION: In patients with advanced NSCLC (aNSCLC), the impact of KRAS mutations (m) and comutations with STK11 and KEAP1 on outcomes across different PD-L1 levels remains incompletely understood. We aimed to investigate the frequency of KRAS mutations and comutations across PD-L1 levels, and the association between these mutations and survival, stratified by PD-L1 expression. METHODS: We conducted a nationwide cohort study of patients diagnosed with aNSCLC between 2016 and 2021 treated with frontline (chemo)immunotherapy, who underwent molecular genotyping including KRAS, STK11, and KEAP1...

Our primary aim was to compare the therapeutic index (tumor-to-bone marrow and tumor-to-kidney absorbed-dose ratios) of the new radiolabeled somatostatin receptor antagonist [177 Lu]Lu-DOTA-JR11 with the established radiolabeled somatostatin receptor agonist [177 Lu]Lu-DOTATOC in the same patients with progressive, standard therapy-refractory meningioma. Methods: In this prospective, single-center, open-label phase 0 study (NCT04997317), 6 consecutive patients were included: 3 men and 3 women (mean age, 63...

BACKGROUND: The Joint Commission reports at least half of communication breakdowns occur during handovers or transitions of care. There is no consensus on how best to approach the transfer of care within Acute Care Surgery (ACS). We conduct a systematic review and meta-analysis of the current data on handoffs and transitions of care in ACS patients and evaluate the impact of standardization and formalized communication processes. METHODS: Clinically relevant questions regarding handoffs and transitions of care with clearly defined patient Population(s), Intervention(s), Comparison(s), and appropriately selected Outcomes (PICO) were determined...

INTRODUCTION: Studies suggest that many emergency department (ED) visits and hospitalizations for cancer patients may be preventable. CMS has implemented changes to the hospital outpatient reporting program that targets acute care in treatment patients for preventable conditions. Oncology urgent care centers aim to streamline patient care. Our cancer center developed an urgent care center called the direct referral unit (DRU) in 2011. METHODS AND MATERIALS: We abstracted visits to our adjacent hospital ED and DRU from January 2014-June 2018...

Brain-derived neurotrophic factor (Bdnf) plays a critical role in brain development, dendritic growth, synaptic plasticity, as well as learning and memory. The rodent Bdnf gene contains nine 5' non-coding exons (I-IXa), which are spliced to a common 3' coding exon (IX). Transcription of individual Bdnf variants, which all encode the same BDNF protein, is initiated at unique promoters upstream of each non-coding exon, enabling precise spatiotemporal and activity-dependent regulation of Bdnf expression. Although prior evidence suggests that Bdnf transcripts containing exon I (Bdnf I) or exon IV (Bdnf IV) are uniquely regulated by neuronal activity, the functional significance of different Bdnf transcript variants remains unclear...

Hemifacial spasm is a neuromuscular disorder caused by compression of the facial nerve at the nerve root entry zone, often due to ectatic or aberrant vasculature. Pathologic compression of the nerve-brainstem interface results in involuntary, paroxysmal contractions of ipsilateral facial muscles that may cause considerable impairments in quality of life. For those with severe symptoms, have positive imaging demonstrating vascular compression, or who fail other management modalities, 1 2 3 4 microvascular decompression offers potential definitive treatment...

The aim of this study was to evaluate immunogenicity and longevity of the humoral immune response within six months after the homologous (BNT162b2/BNT162b2) or heterologous (BBIBP-CorV/BNT162b2) third dose, and to assess breakthrough infections among vaccinees during the Omicron wave in Serbia. Serum samples were analyzed at four timepoints: five months after the primary series; three weeks, three months, and six months after the boost. IgG antibodies against the receptor-binding domain of the spike protein were detected using enzyme-linked fluorescence assay...

BACKGROUND: Few mobile health resistance-based physical activity interventions have targeted community-dwelling adults. "Ecofit" is a multicomponent intervention that promotes resistance and aerobic activities using smartphone technology, outdoor gyms, and social support. This study evaluated process evaluation outcomes of the ecofit randomized controlled trial: (1) the acceptability and usability of the ecofit smartphone app and app user workouts; (2) perceptions of factors influencing outdoor gym use; and (3) the fidelity, reach, recruitment, and dose received of the ecofit program...

The ubiquitous skin colonist Staphylococcus epidermidis elicits a CD8 + T cell response pre-emptively, in the absence of an infection 1 . However, the scope and purpose of this anti-commensal immune program are not well defined, limiting our ability to harness it therapeutically. Here, we show that this colonist also induces a potent, durable, and specific antibody response that is conserved in humans and non-human primates. A series of S. epidermidis cell-wall mutants revealed that the cell surface protein Aap is a predominant target...

PURPOSE: Clinical oncology guidelines recommend addressing sexual and reproductive health (SRH) concerns in routine cancer care. However, limited training often hinders clinicians' ability to do so effectively. The objective of this study was to understand the state of current fellowship education on SRH (ie, sexual health, safe sex practices, and fertility) through conducting a national survey of US hematology/oncology fellowship program directors (PDs). METHODS: A survey was sent to all PDs of adult hematology/oncology fellowship programs in the United States via online link...

Patient interviewing pedagogy in medical education has not evolved to comprehensively capture the biopsychosocial model of healthcare delivery. While gathering a patient's social history targets important aspects of social context it does not adequately capture and account for the real-time reassessment required to understand evolving factors that influence exposure to drivers of health inequities, social determinants of health, and access to supports that promote health. The authors offer a patient interviewing approach called the Contextual Interview (CI) that specifically targets dynamic and ever-changing social context information...

Physical inactivity and loneliness are both associated with health risks and can affect each other through various social and behavioral mechanisms. However, current evidence on this relationship is equivocal and mostly based on cross-sectional data. This longitudinal study aims to determine whether current levels of physical activity (moderate- and vigorous-intensity) and loneliness are associated with future respective states of themselves and each other. Data from waves 6-14 (2002-2018) of the Health and Retirement Study were used (n=20,134) in a mixed-effects and random intercept cross-lagged panel model...
