izing HDL function in the right patients at the optimal time in their disease course. We provide a framework to help the research and clinical communities, as well as funding agencies and stakeholders, obtain insights into current thinking on these topics, and what we predict will be an exciting future for research and development on HDLs.
Evidence suggests that adolescents and young adults (AYAs) with cancer (defined as age 15-39 years) receive high-intensity (HI) medical care at the end-of-life (EOL). Previous population-level studies are limited and lack information on the impact of palliative care (PC) provision. We evaluated prevalence and predictors of HI-EOL care in AYAs with cancer in Ontario, Canada. A secondary aim was to evaluate the impact of PC physicians on the intensity of EOL care in AYAs.

A retrospective decedent cohort of AYAs with cancer who died between 2000 and 2017 in Ontario, Canada, was assembled using a provincial registry and linked to population-based health care data. On the basis of previous studies, the primary composite measure HI-EOL care included any of the following intravenous chemotherapy < 14 days from death, more than one emergency department visit, and more than one hospitalization or intensive care unit admission < 30 days from death. Secondary measures included the most invasive (MI) EOL care (eg, mechanical ventilation < 14 days from death) and PC physician involvement. We determined predictors of outcomes using appropriate regression models.

Of 7,122 AYAs, 43.8% experienced HI-EOL care. PC physician involvement (odds ratio [OR], 0.57; 95% CI, 0.51 to 0.63) and older age at death (OR, 0.60; 95% CI, 0.48 to 0.74) were associated with a lower risk of HI-EOL care. AYAs with hematologic malignancies were at highest risk for HI and MI-EOL care. PC physician involvement substantially reduced the odds of mechanical ventilation at EOL (OR, 0.36; 95% CI, 0.30 to 0.43).

A large proportion of AYAs with cancer experience HI-EOL care. Our study provides strong evidence that PC physician involvement can help mitigate the risk of HI and MI-EOL care in AYAs with cancer.

Population-based cancer incidence rates of bladder cancer may be underestimated. Accurate estimates are needed for understanding the burden of bladder cancer in the United States. We developed and evaluated the feasibility of a machine learning-based classifier to identify bladder cancer cases missed by cancer registries, and estimated the rate of bladder cancer cases potentially missed.

Data were from population-based cohort of 37,940 bladder cancer cases 65 years of age and older in the SEER cancer registries linked with Medicare claims (2007-2013). Cases with other urologic cancers, abdominal cancers, and unrelated cancers were included as control groups. A cohort of cancer-free controls was also selected using the Medicare 5% random sample. We used five supervised machine learning methods classification and regression trees, random forest, logic regression, support vector machines, and logistic regression, for predicting bladder cancer.

Registry linkages yielded 37,940 bladder cancer cases and 766,303 cancer-free controls. Using health insurance claims, classification and regression trees distinguished bladder cancer cases from noncancer controls with very high accuracy (95%). Bacille Calmette-Guerin, cystectomy, and mitomycin were the most important predictors for identifying bladder cancer. From 2007 to 2013, we estimated that up to 3,300 bladder cancer cases in the United States may have been missed by the SEER registries. This would result in an average of 3.5% increase in the reported incidence rate.

SEER cancer registries may potentially miss bladder cancer cases during routine reporting. These missed cases can be identified leveraging Medicare claims and data analytics, leading to more accurate estimates of bladder cancer incidence.

Oral chemotherapy challenges providers' abilities to safely monitor patients' symptoms, adherence, and financial toxicity. COVID-19 has increased the urgency of caring for patients remotely. Collection of electronic patient-reported outcomes (ePROs) has demonstrated efficacy for patients on intravenous chemotherapy, but limited data support their use in oral chemotherapy. We undertook a pilot project to assess the feasibility of implementing an ePRO system for patients starting oral chemotherapy at our cancer center, which includes both an academic site and a community site.

Patients initiating oral chemotherapy were asked to participate. A five-question tool was built in REDCap. Concerning responses triggered outreach within one business day. The primary outcome was time to first symptom assessment. For comparison, we used a historical cohort of patients who had been prescribed oral chemotherapies by providers in the same disease groups at the cancer center.

Twenty-five of 62 (40%) patients completed es time to symptom assessment. Further investigation is needed to improve patient engagement with ePROs and evaluate the long-term impacts for patients on oral chemotherapy.
To inform precision oncology, methods are needed to use electronic health records (EHRs) to identify patients with cancer who are experiencing clinical inflection points, consistent with worsening prognosis or a high propensity to change treatment, at specific time points. Such patients might benefit from real-time screening for clinical trials.

Using serial unstructured imaging reports for patients with solid tumors or lymphoma participating in a single-institution precision medicine study, we trained a deep neural network natural language processing (NLP) model to dynamically predict patients' prognoses and propensity to start new palliative-intent systemic therapy within 30 days. Model performance was evaluated using Harrell's c-index (for prognosis) and the area under the receiver operating characteristic curve (AUC; for new treatment and new clinical trial enrollment). Associations between model outputs and manual annotations of cancer progression were also evaluated using the AUC.

The COVID-19 pandemic has induced historic educational disruptions. In April 2021, about 40% of U.S. public school students were not offered full-time in-person education.

To assess the risk for SARS-CoV-2 transmission in schools.

An agent-based network model was developed to simulate transmission in elementary and high school communities, including home, school, and interhousehold interactions.

School structure was parametrized to reflect average U.S. classrooms, with elementary schools of 638 students and high schools of 1451 students. Daily local incidence was varied from 1 to 100 cases per 100000 persons.

Students, faculty, staff, and adult household members.

Isolation of symptomatic individuals, quarantine of an infected individual's contacts, reduced class sizes, alternative schedules, staff vaccination, and weekly asymptomatic screening.

Transmission was projected among students, staff, and families after a single infection in school and over an 8-week quarter, contingent on local incidenf Allergy and Infectious Diseases, National Institute on Drug Abuse, and Facebook.

Cornerstones of inpatient management include fluid resuscitation; blood transfusion; endoscopy; and initiation of proton-pump inhibitor therapy, which continues in an individualized manner based on risk factors for recurrent bleeding in the outpatient setting. The International Consensus Group released guidelines on the management of nonvariceal upper gastrointestinal bleeding in 2019. These guidelines provide a helpful, evidence-based roadmap for management of gastrointestinal bleeding but leave certain management details to the discretion of the treating physician. Here, 2 gastroenterologists consider the care of a patient with nonvariceal upper gastrointestinal bleeding from a peptic ulcer, specifically debating approaches to blood transfusion and endoscopy timing in the hospital, as well as the recommended duration of proton-pump inhibitor therapy after discharge.Many groundbreaking advances have occurred in the field of multiple sclerosis since this series last reviewed the disorder in 2014. The U.S. HTH-01-015 chemical structure Food and Drug Administration has approved 7 new medications for relapsing-remitting multiple sclerosis and approved the first medication for primary progressive multiple sclerosis. The McDonald criteria for diagnosing multiple sclerosis were updated in 2017. New blood tests can now differentiate patients with multiple sclerosis from those with neuromyelitis optica spectrum disorder, and 3 new medications have been approved specifically for the latter disorder. Also, new medications for treating the symptoms of multiple sclerosis have been introduced.Immune checkpoint receptors (ICRs) were recently found to modulate the anti-tumoral immune response. This study aimed to determine the clinical and pathological associations of ICRs expression on tumor-infiltrating lymphocytes (TILs) in patients with locally advanced breast cancer (LABC) treated with neoadjuvant chemotherapy (NAC). Expressions of ICRs including PD-1, LAG-3, TIM-3, TIGIT, and CTLA-4 on CD8+ T lymphocytes and Natural Killer (NK) cells on TILs were analyzed by flow cytometry. Patients less then 50 years were more likely to express CTLA-4 on CD8+ T lymphocytes compared to those ≥ 50 years (p = 0.004). In addition, patients with ypT3-4 tumors were more likely to have increased LAG-3 expression on CD16-CD56bright NK cells (p = 0.042) and PD-1 (p = 0.014) and CTLA-4 (p = 0.018) expressions on CD8+ T cells in regard to those with ypT1-T2, respectively. Contrarily, PD-1 expression on CD16-CD56bright NK cells was found to be decreased in patients with ypN+ compared to those with ypN- (p = 0.022). Furthermore, patients with HER2+ tumors were more likely to have increased TIM-3 expression on CD8+ T cells (p = 0.043), whereas patients with a better response to NAC were more likely to express TIGIT on CD8+ T (p = 0.014) and CD16- CD56bright NK cells (p = 0.003), respectively. The new generation ICRs, TIM-3, LAG-3, and TIGIT are highly expressed in LABC following NAC in patients with poor prognostic factors. Therefore, new evolving therapies using inhibitory mAbs directed to TIM-3, LAG-3, and TIGIT could be also be considered in locally advanced breast cancers expressing these ICRs.Due to tumor heterogeneity, the consistency of programmed cell death-ligand 1 (PD-L1) expression between circulating tumor cells (CTCs) and tissue is controversial. This study aimed to establish a method for detecting CTC PD-L1 expression and exploring the impact of the same on the prognosis of lung cancer. In 32 patients with non-small cell lung cancer, lung cancer cells in the blood were enriched using CD326 immunomagnetic beads. Goat anti-mouse polyclonal CD326 antibody stained the epithelial lung cancer cells and anti-PD-L1 antibody was used to detect the expression of CTC PD-L1. The DAKO Link 48 automatic staining device detected the expression in lung cancer tissue. The consistency of PD-L1 expression was analyzed in lung cancer tissue and CTCs. The effect of plasma interferon gamma, tumor necrosis factor alpha, and interleukin-2 on PD-L1 expression and prognosis was analyzed. The number of CTCs detected in patients was 1-36, with a median of 2. There was no significant difference in PD-L1 expression fractions between CTCs and paired tumor tissue (p>0.
