Immune checkpoint inhibitors (ICIs) show limited success in treating pancreatic ductal adenocarcinoma (PDAC), largely due to immune evasion mechanisms, including downregulating expression of major histocompatibility complex class I (MHC-I). Our retrospective analysis demonstrated that smoking - a state of elevated CO exposure - is correlated with increased MHC I expression in pancreatic tumors. Here we tested our hypothesis that introducing exogenous CO augments the anti-cancer effects of immunotherapy.

This study introduces composite hyaluronic acid gas-entrapping materials (GEMs) delivering carbon monoxide (CO) to promote wound healing in pigs. These composite materials facilitate burst release followed by sustained release of CO over 48 h.

Despite the rapidly accumulating information on extracellular vesicles (EVs) from most other bacteria, nothing is known about Spirulina extracellular vesicles (SPEVs). This study reports the successful isolation, characterization and visualization of SPEVs for the first time and it further investigates the potential therapeutic benefits of SPEVs using a mouse model.

DB-related symptoms can be measured with the 25-item Self Evaluation of Breathing Questionnaire (SEBQ). However, the SEBQ is not available in Danish.

There is no standard or guidance for how best to develop and implement pain interdisciplinary teams within complex health care systems.
Objectives: The purpose of this quality improvement project was to evaluate the effectiveness of the standard 9-step Lean 6 Sigma (LSS) methodology in redesigning a pre-existing VA outpatient pain clinic solely offering interventional pain services into an efficient, sustainable pain IDT program.
The use of amorphous solid dispersions (ASDs) in commercial drug products has increased in recent years due to the large number of poorly soluble drugs in the pharmaceutical pipeline. However, the release behavior of ASDs is complex and remains not well understood. Often, the drug release from ASDs is rapid and complete at lower drug loadings (DLs) but becomes slow and incomplete at higher DLs.

Background: Despite the various anticancer activities of tocopherols, little is known about tocopherols associated with lung cancer risk among low-income African Americans (AA) and European Americans (EA) who are disproportionately affected by the disease.
Methods: We conducted a nested case-control study that included 209 incident lung cancer cases and 406 matched controls within the Southern Community Cohort Study. Using biospecimens collected at cohort enrollment, plasma levels of α-, β/γ-, δ-, and total-tocopherols were measured by high-performance liquid chromatography with photodiode array detection.
Cytisine (CYT) is a quinolizidine alkaloid used for nicotine addiction treatment. Recent clinical trial data regarding cytisine confirm its high effectiveness and safety as a smoking cessation treatment. CYT's popularity is growing due to its increased availability and licensing in more countries worldwide.

It is widely accepted that the biomedical model is outdated and research on the biopsychosocial model of chronic pain has increased in recent years, concurrent with investigations into self-management of chronic pain. The Veterans Health Administration (VHA) has incorporated both of these approaches into their Whole Health System.

The aim of this study was to tailor CONSORT (Consolidated Standards of Reporting Trials)-SPI (Social and Psychological Interventions) guidelines to improve reporting of trials of behavioural interventions to promote smoking cessation.
Method: Informed by missing data from the IC-SMOKE (Intervention and Comparison group support provided in SMOKing cEssation) systematic review project, this study used a multi-stage Delphi process to examine which items could be added or modified to improve the reporting of smoking cessation trials.
Amid the COVID-19 pandemic, higher education faculty at a Jesuit university were compelled to adapt pedagogies that were immersive and learner-centered within a virtual learning environment. The Ignatian pedagogical paradigm presented in this article is based on a practical teaching context that values Ignatian principles and world views while promoting Jesuit education. This educational interventional study measured the transformation of nursing student online learners into active, caring, and compassionate participants as they developed their nursing knowledge in a maternal-child health course.

Our hypothesis is that there is no practical or feasible systems-change approach to guide staff, researchers, or consumers through the complex transition that is required for the sustained uptake of IC across diverse clinical settings. To address this gap, we combined clinical and consumer expertise with the best available research evidence to develop a framework to drive the uptake of IC.

These patients are often less responsive to traditional speech-language pathology treatments and there is emerging literature that suggests dysfunctional breathing (DB) might contribute to dyspnea and other symptoms in this patient population. Treatment of DB through breathing retraining has been shown to improve breathing and successfully reduce symptoms similar to those seen in patients with long COVID.
View Article and Find Full Text PDFThe Veterans Health Administration has always been a leader in the innovation and implementation of evidence-based care. The use of the stepped care model of chronic pain has led to several novel interventions and strong practices in the last several years at each level of care with regard to education, use of technology, and increasing access to evidence-based care (eg, behavioral health, interdisciplinary teams). The Whole Health model is also being implemented nationwide and has the potential to significantly affect chronic pain treatment in the coming decade.

In addition, we monitored the leachate quality of the amended BR under progressive leaching that simulated precipitation conditions in Northern Brazil. Free-draining column tests consisting of BR amended with gypsum and organic waste, at 5% and 10% w/w, respectively, were leached for 8 weeks to assess the effects on the chemical composition of BR and the leachates.

This systematic review aimed to identify factors associated with sustained abstinence in people experiencing severe mental illness following a smoking intervention.
Method: Searches were conducted in PubMed, PsycInfo, Scopus, Embase, Emcare, CINAHL and Cochrane Library from the inception of the e-databases until June 2022.
Tobacco use continues to be a leading cause of death and morbidity globally. At the core of Australia's response to tobacco-related harms is the National Tobacco Strategy which highlights a national collaborative framework to reduce prevalence, and associated health, social and economic impacts of tobacco use. A draft National Tobacco Strategy (2022-2030) has recently been released for consultation and as members of the Australasian Professional Society on Alcohol and other Drugs' Special Interest Group for Smoking Cessation Professionals we provide a commentary on key successes of the previous National Tobacco Strategy, and suggestions for improvement areas to strengthen Australia's policy response to tobacco and e-cigarette-related issues.

However, few data are available for the long-term use of CWs treating alkaline leachates nor the activity of microbes within them. To investigate the feasibility of CW to buffer alkaline pH, a pilot-scale wetland was implemented in 2015 to treat alkaline bauxite residue leachate.
