Low diffusion capacity predicts poor prognosis in extensive stage small cell lung cancer: a single-center analysis of 10 years.

Background: Poor pulmonary function and chronic obstructive pulmonary disease (COPD) are associated with poorer overall survival (OS) in non-small-cell lung cancer (NSCLC) patients. Few studies have investigated the association between pulmonary function and OS in small-cell lung cancer (SCLC) patients. We compared the clinical characteristics of extensive disease SCLC (ED-SCLC) with or without moderately impaired diffusion capacity for carbon monoxide (DLco) and investigated the factors associated with survival in ED-SCLC patients.

Building medication for opioid use disorder prescriber capacity during the opioid epidemic: Prescriber recruitment trends and methods.

Introduction: Physicians are a critical clinical resource for patient care. Yet physician recruitment has been considerably understudied, particularly in substance use disorder (SUD) settings. This study proposes a conceptual model called the "Physician Recruitment Descriptive Factors Framework" to investigate the role of environmental, organizational, and individual factors in the use of physician recruitment strategies.

Extending the actor-partner interdependence model to accommodate multivariate dyadic data using latent variables.

This study extends the traditional Actor-Partner Interdependence model (APIM; Kenny, 1996) to incorporate dyadic data with multiple indicators reflecting latent constructs. Although the APIM has been widely used to model interdependence in dyads, the method and its applications have largely been limited to single sets of manifest variables. This article presents three extensions of the APIM that can be applied to multivariate dyadic data; a manifest APIM linking multiple indicators as manifest variables, a composite-score APIM relating univariate sums of multiple variables, and a latent APIM connecting underlying constructs of multiple indicators.

Enhancing Use of Medications for Opioid Use Disorder Through External Coaching.

Objective: This randomized controlled trial tested whether external coaching influences addiction treatment providers' utilization of medications to treat opioid use disorder (MOUDs).

Methods: This study recruited 75 unique clinical sites in Florida, Ohio, and Wisconsin, including 61 sites in specialty treatment agencies and 14 behavioral health sites within health systems. The trial used external coaching to increase use of MOUDs in the context of a learning collaborative and compared it with no coaching and no learning collaborative (control condition).

Evaluating sensitivity to classification uncertainty in latent subgroup effect analyses.

Background: Increasing attention is being given to assessing treatment effect heterogeneity among individuals belonging to qualitatively different latent subgroups. Inference routinely proceeds by first partitioning the individuals into subgroups, then estimating the subgroup-specific average treatment effects. However, because the subgroups are only latently associated with the observed variables, the actual individual subgroup memberships are rarely known with certainty in practice and thus have to be imputed.

Prescribers' satisfaction with delivering medications for opioid use disorder.

Background: Expanding access to medications for opioid use disorder (MOUD), such as buprenorphine and extended release (XR) naltrexone, is critical to addressing the US opioid epidemic, but little is known about prescriber satisfaction with delivering these two types of MOUD. The current study describes the satisfaction of prescribers delivering buprenorphine and XR-naltrexone while examining whether satisfaction is associated with current patient census and organizational environment.

Methods: As part of a cluster randomized clinical trial (RCT) focused on expanding access to medication for opioid use disorder, 41 MOUD prescribers in Florida, Ohio, and Wisconsin completed a web-based survey.

Bombesin-Tethered Reactive Oxygen Species (ROS)-Responsive Nanoparticles for Monomethyl Auristatin F (MMAF) Delivery.

Dolastatin derivatives, represented by monomethylauristatin E (MMAE), have been translated in clinic with a form of antibody-drug conjugate; however, their potential in nanoparticle systems has not been well established due to the potential risk of immature release of extremely high cytotoxic dolastatin drugs during blood circulation. Herein, we rationally propose monomethylauristatin F (MMAF), a dolastatin-derived, loaded nanoparticle system composed of bombesin (BBN)-tethered ROS-responsive micelle system (BBN-PEG-PPADT) to achieve efficient anticancer therapy with targeted and efficient delivery of MMAF. The developed MMAF-loaded BBN-PEG-PPADT micelles (MMAF@BBN-PEG-PPADT) exhibited improved cellular uptake via interactions between BBN and gastrin-releasing peptide receptors on the cancer cells and the intracellular burst release of MMAF, owing to the ROS-responsive disruption, which allowed the efficient anticancer effects of MMAF in vitro.

NIATx-TI versus typical product training on e-health technology implementation: a clustered randomized controlled trial study protocol.

Background: Substance use disorders (SUDs) lead to tens-of-thousands of overdose deaths and other forms of preventable deaths in the USA each year. This results in over $500 billion per year in societal and economic costs as well as a considerable amount of grief for loved ones of affected individuals. Despite these health and societal consequences, only a small percentage of people seek treatment for SUDs, and the majority of those that seek help fail to achieve long-term sobriety.

Random Forests Approach for Causal Inference with Clustered Observational Data.

There is a growing interest in using machine learning (ML) methods for causal inference due to their (nearly) automatic and flexible ability to model key quantities such as the propensity score or the outcome model. Unfortunately, most ML methods for causal inference have been studied under single-level settings where all individuals are independent of each other and there is little work in using these methods with clustered or nested data, a common setting in education studies. This paper investigates using one particular ML method based on random forests known as Causal Forests to estimate treatment effects in multilevel observational data.

Increasing Engagement in Post-Withdrawal Management Services Through a Practice Bundle and Checklist.

Individuals with substance use disorders (SUDs) who engage in post-withdrawal management (or detoxification) continuing care are more likely to remain drug free or sober and less likely to be incarcerated or die of overdose. Yet, just 21-35% of individuals receiving emergency withdrawal management services receive continuing care. This deficiency is occurring, while overdose rates are high, and limited evidence exists on how to improve this vital transition.

Comprehensive Effects of Organized Education for Patients with Chronic Obstructive Pulmonary Disease.

Background: Despite the increasing prevalence of chronic obstructive pulmonary disease (COPD) worldwide, knowledge and awareness of COPD remain extremely low. This prospective study aimed to demonstrate the effectiveness of organized educational intervention.

Patients And Methods: The study participants included patients diagnosed with COPD and receiving inhaler treatment.

Physicians' satisfaction with providing buprenorphine treatment.

Background: Buprenorphine is a critically important treatment for addressing the opioid epidemic, but there are virtually no studies of physicians' job satisfaction with providing buprenorphine. Physicians' job satisfaction has been linked to burnout and turnover as well as patients' adherence to treatment recommendations, so it is important to understand how physicians' satisfaction with providing buprenorphine treatment compares to their overall job satisfaction.

Methods: As part of a cluster randomized clinical trial (RCT) focused on expanding access to medication for opioid use disorder, 55 physicians working in 38 organizations in Florida, Ohio, and Wisconsin completed a baseline web-based survey.

The payer's role in addressing the opioid epidemic: It's more than money.

Background And Objective: County, State, and Federal agencies are addressing the public health opioid crisis. Ohio's 51 county-based Alcohol, Drug Addiction and Mental Health Services (ADAMHS) Boards finance and regulate opioid treatment services within their jurisdictions. This three-year comparative trial collaborated with ADAMHS Boards (n = 14) to test the Advancing Recovery Framework, a suite of organizational and system change strategies designed to promote use of buprenorphine for opioid agonist therapy.

Pharmacotherapy, Resource Needs, and Physician Recruitment Practices in Substance Use Disorder Treatment Programs.

Objectives: Effective pharmacological treatments for opioid use disorder (OUD) continue to be underutilized, particularly within specialty substance use disorder (SUD) treatment organizations. Few studies have examined whether specific practices to recruit prescribers, financial needs, and human resource needs facilitate or impede the implementation of pharmacotherapy.

Methods: Surveys were completed by administrators from 160 treatment programs in Florida, Ohio, and Wisconsin.

Low-power and low-drug-dose photodynamic chemotherapy via the breakdown of tumor-targeted micelles by reactive oxygen species.

Tumor-targeted delivery of anticancer agents using nanocarriers has been explored to increase the therapeutic index of cancer chemotherapy. However, only a few nanocarriers are clinically available because the physiological complexity often compromises their ability to target, penetrate, and control the release of drugs. Here, we report a method which dramatically increases in vivo therapeutic drug efficacy levels through the photodynamic degradation of tumor-targeted nanocarriers.

Minimal change disease related to rifampicin presenting with acute renal failure during treatment for latent tuberculosis infection: A case report.

Rationale: The standard drugs used to treat tuberculosis are rifampicin and isoniazid. These agents are usually safe and inexpensive for short-term use in treatment of latent tuberculosis infection, but sometimes cause adverse renal effects, including minimal change disease (MCD).

Patient Concerns: Here, we report a 51-year-old woman with latent tuberculosis infection who developed nephrotic syndrome during treatment with rifampicin and isoniazid for 25 days.

A first case report of pulmonary hyalinizing granuloma associated with immunoglobulin A nephropathy.

Rationale: Pulmonary hyalinizing granuloma (PHG) is a rare benign disease that has been shown to be associated with the deposition of immune complexes in the lung parenchyma caused by infection or autoimmune diseases. There have been no reports of PHG in association with immunoglobulin A nephropathy (IgAN).

Patient Concerns: A 30-year-old woman visited with a 12-month history of dyspnea on exertion and cough that had worsened 1 month before her visit.

Payer Policy Behavior Towards Opioid Pharmacotherapy Treatment in Ohio.

Objective: Few studies examine how payers address the need for improved access to pharmacotherapy for opioid use disorders and the influence of environmental variables on access to opioid agonist and antagonist medications.

Method: The 52 Ohio Addiction Drug Abuse and Mental Health Services (ADAMHS) Boards that disburse funds for treatment services for the uninsured and underinsured were surveyed to assess coverage for opioid agonist and antagonist treatment medications. Analyses examined public health data on regional opioid addiction patterns, characteristics of the local health insurance market, and their associations with coverage for opioid addiction pharmacotherapy.

Engineered Zn(II)-Dipicolylamine-Gold Nanorod Provides Effective Prostate Cancer Treatment by Combining siRNA Delivery and Photothermal Therapy.

Combination cancer treatment has emerged as a critical approach to achieve remarkable anticancer effect. In this study, we prepared a theranostic nanoformulation that allows for photoacoustic imaging as well as combination gene and photothermal therapy. Gold nanorods (GNR) were coated with dipicolyl amine (DPA), which forms stable complexes with Zn cations.

Test of a workforce development intervention to expand opioid use disorder treatment pharmacotherapy prescribers: protocol for a cluster randomized trial.

Background: Overdoses due to non-medical use of prescription opioids and other opiates have become the leading cause of accidental deaths in the USA. Buprenorphine and extended-release naltrexone are key evidence-based pharmacotherapies available to addiction treatment providers to address opioid use disorder (OUD) and prevent overdose deaths. Treatment organizations' efforts to provide these pharmacotherapies have, however, been stymied by limited success in recruiting providers (physicians, nurse practitioners, and physician assistants) to prescribe these medications.

Lipiodol nanoemulsions stabilized with polyglycerol-polycaprolactone block copolymers for theranostic applications.

Background: Polyglycerol is an attractive hydrophilic building block of amphiphilic copolymers for biomedical and pharmaceutical applications due to its biocompatibility, facile chemical modification, and anti-fouling activity. Herein we introduce theranostic nanoemulsions incorporating anti-cancer therapeutic and contrast agents using linear polyglycerol-poly(ε-caprolactone) diblock copolymers (PG--PCL). Lipiodol is used as a core oil that dissolves paclitaxel and serves as a contrast agent for computer tomography (CT).

Polyglycerolated nanocarriers with increased ligand multivalency for enhanced in vivo therapeutic efficacy of paclitaxel.

Despite the excellent biocompatibility and antifouling effect of poly(ethylene glycol) (PEG), the high steric hindrance, limited chemical functionality, and low ligand multivalency of PEGylated nanocarriers often lead to inefficient cell targeting and intracellular trafficking. Hence, a new structure of hydrophilic corona allowing a higher ligand density without loss of excellent biocompatibility is highly desirable. Here we introduce tumor-targeted polyglycerolated (PGylated) nanocarriers that dramatically enhance the in vivo therapeutic efficacy of incorporated paclitaxel simply by increasing the surface density of hydrophobic tumor-targeting ligands.

Cognitive Resilience and Psychological Responses across a Collegiate Rowing Season.

Introduction: Student-athletes face numerous challenges across their competitive season. Although mood states have been previously studied, little is known about adaptations in other psychological responses, specifically cognition. The purpose of this study was to characterize cognitive function, mood, sleep, and stress responses at select time points of a season in collegiate rowers.

Amphiphilic siRNA Conjugates for Co-Delivery of Nucleic Acids and Hydrophobic Drugs.

Combination therapy of nucleic acids and chemical drugs for cancer treatment is a promising strategy to enhance the therapeutic efficacy by simultaneously regulating multiple troublesome pathways. In this study, we report on polyethylene glycol-siRNA-polycaprolactone (PEG-siRNA-PCL) micelles that encapsulate hydrophobic drugs for efficient co-delivery of siRNA and drugs to cancer cells. Amphiphilic PEG-siRNA-PCL copolymers were synthesized by annealing antisense siRNA-PCL conjugates with sense siRNA-PEG conjugates.
