Pharmacist E-script transcription service initiated nicotine replacement therapy uptake in pre-admission clinic: A pilot study.

Background: Pharmacist-led smoking cessation programs in pre-admission clinics (PAC) have shown to increase quit attempts and achieve abstinence by the day of surgery (DOS).

Aims: To evaluate the feasibility of Pharmacist E-script Transcription Service (PETS) initiated nicotine replacement therapy (NRT) in PAC, including smoking cessation on DOS.

Methods: A single centre, pre and post-intervention pilot study conducted at an Australian public hospital PAC.

A pre and post interventional audit of an 'apple juice on arrival' protocol to reduce excessive clear fluid fasting times in paediatric patients.

Many studies have reported prolonged fasting times in children, associated with negative metabolic and behavioural outcomes. We felt that although our paediatric preoperative clear fluid fasting guideline was only for 2 hours, prolonged fasting still occurred for some patients. We conducted an audit of paediatric fasting times, before and after introducing a new protocol of 'apple juice on arrival', in which, on arrival to the children's ward, all children received 3 ml/kg of apple juice.

Varenicline and Nicotine Replacement Therapy for Smokers Admitted to Hospitals: A Randomized Clinical Trial.

Importance: Varenicline is the most effective sole pharmacotherapy for smoking cessation. If used in combination with nicotine replacement therapy (NRT), cessation rates may be further improved, but the efficacy and safety of the combination need to be evaluated.

Objective: To examine whether hospitalized smokers treated with varenicline and NRT lozenges achieve higher prolonged smoking abstinence rates compared with those treated with varenicline alone.

Does offering small financial incentives to smokers at the time of being wait-listed for surgery increase smoking cessation by the day of surgery? A randomised feasibility trial.

Objective: This study aims to assess whether offering small financial incentives to smokers on elective surgery wait-lists is feasible and increases quitting before surgery.

Design: Randomised controlled trial, prospective, double-blinded.

Setting: Single-centre, Australian metropolitan public hospital.

CellBiAge: Improved single-cell age classification using data binarization.

Aging is a major risk factor for many diseases. Accurate methods for predicting age in specific cell types are essential to understand the heterogeneity of aging and to assess rejuvenation strategies. However, classifying organismal age at single-cell resolution using transcriptomics is challenging due to sparsity and noise.

Epidemiology and molecular characterization of avian influenza A viruses H5N1 and H3N8 subtypes in poultry farms and live bird markets in Bangladesh.

Avian influenza virus (AIV) remains a global threat, with waterfowl serving as the primary reservoir from which viruses spread to other hosts. Highly pathogenic avian influenza (HPAI) H5 viruses continue to be a devastating threat to the poultry industry and an incipient threat to humans. A cross-sectional study was conducted in seven districts of Bangladesh to estimate the prevalence and subtypes (H3, H5, and H9) of AIV in poultry and identify underlying risk factors and phylogenetic analysis of AIVs subtypes H5N1 and H3N8.

Single-cell transcriptomics of peripheral blood in the aging mouse.

Compositional and transcriptional changes in the hematopoietic system have been used as biomarkers of immunosenescence and aging. Here, we use single-cell RNA-sequencing to study the aging peripheral blood in mice and characterize the changes in cell-type composition and transcriptional profiles associated with age. We identified 17 clusters from a total of 14,588 single cells.

Stem cell phenotype predicts therapeutic response in glioblastomas with MGMT promoter methylation.

A growing body of evidence supports the presence of a population of cells in glioblastoma (GBM) with a stem cell-like phenotype which shares certain biological markers with adult neural stem cells, including expression of SOX2, CD133 (PROM1), and NES (nestin). This study was designed to determine the relationship between the expression of these stem cell markers and the clinical outcome in GBM patients. We quantified the intensity of expression of the proteins CD133 and SOX2 by immunohistochemistry (IHC) in a cohort of 86 patients with IDH-wildtype GBM, and evaluated patient outcomes using Kaplan-Meier and Cox proportional hazards analysis.

FOXO3 regulates a common genomic program in aging and glioblastoma stem cells.

Background: Glioblastoma (GBM) is an aggressive, age-associated malignant glioma that contains populations of cancer stem cells. These glioma stem cells (GSCs) evade therapeutic interventions and repopulate tumors due to their existence in a slowly cycling quiescent state. Although aging is well known to increase cancer initiation, the extent to which the mechanisms supporting GSC tumorigenicity are related to physiological aging remains unknown.

Single-cell analysis of the aging female mouse hypothalamus.

Alterations in metabolism, sleep patterns, body composition, and hormone status are all key features of aging. While the hypothalamus is a well-conserved brain region that controls these homeostatic and survival-related behaviors, little is known about the intrinsic features of hypothalamic aging. Here, we perform single nuclei RNA-sequencing of 40,064 hypothalamic nuclei from young and aged female mice.

Understanding the aging hypothalamus, one cell at a time.

The hypothalamus is a brain region that integrates signals from the periphery and the environment to maintain organismal homeostasis. To do so, specialized hypothalamic neuropeptidergic neurons control a range of processes, such as sleep, feeding, the stress response, and hormone release. These processes are altered with age, which can affect longevity and contribute to disease status.

Which smokers enroll in a hospital based smoking cessation trial? Survey of smoking related behaviors, quit attempts, and motivation to quit.

Background: Understanding smoking behaviors in hospital patients who smoke may improve inpatient cessation treatments. This study aimed to describe smoking-related behaviors, past-quit attempts, and self-reported difficulties experienced in quitting among those who enrolled in a smoking cessation trial of varenicline.

Methods: Baseline data were obtained from adult hospitalized smokers (average ≥ 10 cigarettes/day in 4-weeks prior to hospitalization) who enrolled in a randomized, placebo-controlled trial of varenicline ± nicotine lozenges at five Australian public hospitals.

Offering mailed nicotine replacement therapy and Quitline support before elective surgery: a randomised controlled trial.

Objective: To assess whether offering free mailed nicotine replacement therapy (NRT) and telephone counselling to smokers on elective surgery waiting lists increases quitting before surgery.

Design, Setting: Randomised, controlled trial at Frankston Hospital, a public tertiary referral hospital in Melbourne.

Participants: Adult smokers added to elective surgery waiting lists for operations at least ten days in the future, 1 April 2019 - 3 April 2020.

Corticotropin Releasing Factor Binding Protein as a Novel Target to Restore Brain Homeostasis: Lessons Learned From Alcohol Use Disorder Research.

Stress is well-known to contribute to the development of many psychiatric illnesses including alcohol and substance use disorder (AUD and SUD). The deleterious effects of stress have also been implicated in the acceleration of biological age, and age-related neurodegenerative disease. The physio-pathology of stress is regulated by the corticotropin-releasing factor (CRF) system, the upstream component of the hypothalamic-pituitary-adrenal (HPA) axis.

Adverse effects associated with bupropion therapeutic errors in adults reported to four United States Poison Centers.

Context: Bupropion is a frequently used medication. Excessive doses may cause altered mental status, seizures, and dysrhythmias. There is a need for accurate estimate of seizure risk with therapeutic errors and determination if minor symptoms are harbingers of more severe effects.

Intravenous phytonadione administered orally in reducing warfarin-related coagulopathy.

Introduction: The cost of phytonadione tablets has increased markedly and is significantly higher than the intravenous formulation. The intravenous formulation given orally is a potential alternative but has not been directly evaluated in comparison to the commercially available tablet. The objective of this study was to evaluate the efficacy of phytonadione intravenous solution given orally compared to commercially available phytonadione tablets for reversal of coagulopathy related to warfarin.

Altered Chromatin States Drive Cryptic Transcription in Aging Mammalian Stem Cells.

A repressive chromatin state featuring trimethylated lysine 36 on histone H3 (H3K36me3) and DNA methylation suppresses cryptic transcription in embryonic stem cells. Cryptic transcription is elevated with age in yeast and nematodes, and reducing it extends yeast lifespan, though whether this occurs in mammals is unknown. We show that cryptic transcription is elevated in aged mammalian stem cells, including murine hematopoietic stem cells (mHSCs) and neural stem cells (NSCs) and human mesenchymal stem cells (hMSCs).

Changing and stable chromatin accessibility supports transcriptional overhaul during neural stem cell activation and is altered with age.

Neural stem cells (NSCs) in the adult and aged brain are largely quiescent, and require transcriptional reprogramming to re-enter the cell cycle. However, the mechanisms underlying these changes and how they are altered with age remain undefined. Here, we identify the chromatin accessibility differences between primary neural stem/progenitor cells in quiescent and activated states.
