Tobacco, nicotine, and cannabis use and exposure in an Australian Indigenous population during pregnancy: A protocol to measure parental and foetal exposure and outcomes.

Background: The Australian National Perinatal Data Collection collates all live and stillbirths from States and Territories in Australia. In that database, maternal cigarette smoking is noted twice (smoking <20 weeks gestation; smoking >20 weeks gestation). Cannabis use and other forms of nicotine use, for example vaping and nicotine replacement therapy, are nor reported.

Discovery of Monovalent Direct Degraders of BRD4 That Act Via the Recruitment of DCAF11.

Targeted protein degradation (TPD) using the ubiquitin proteasome system (UPS) is a rapidly growing drug discovery modality to eliminate pathogenic proteins. Strategies for TPD have focused on heterobifunctional degraders that often suffer from poor drug-like properties, and molecular glues that rely on serendipitous discovery. Monovalent "direct" degraders represent an alternative approach, in which small molecules bind to a target protein and induce degradation of that protein through the recruitment of an E3 ligase complex.

Differences in microenvironment of lung cancer and pleural effusions by single-cell RNA sequencing.

Background: Direct comparison of tumor microenvironment of matched lung cancer biopsies and pleural effusions (PE) from the same patients is critical in understanding tumor biology but has not been performed. This is the first study to compare the lung cancer and PE microenvironment by single-cell RNA sequencing (scRNA-seq).

Methods: Matched lung cancer biopsies and PE were obtained prospectively from ten patients.

Restricting supply of tobacco products to pharmacies: a scoping review.

Objective: We synthesised the published literature on proposals to restrict tobacco supply to pharmacies, covering (1) policy concept/rationale/attempts, (2) policy impact and implementation and (3) policy and research recommendations.

Data Sources: We searched eight databases (PubMed, CINAHL, Scopus, Web of Science, Embase, IPA, ProQuest and OATD) for publications with at least an English-language abstract. We searched reference lists of included publications manually.

Pharmacist-only supply of nicotine vaping products: proposing an alternative regulatory model for Australia.

Regulation of nicotine vaping products (NVPs) is an ongoing challenge across the world. Australia currently has a globally unique NVP regulatory model that requires a medical prescription to purchase and use NVPs, with further restrictions in progress in response to evidence of widespread illicit NVP sales. Against this background, we examine the new measures and consider a modification of the model to pharmacist-only supply as an option for increasing access to NVPs for smoking cessation, while retaining health practitioner oversight of supply.

Medication Lubricants for Oral Delivery of Drugs: Oral Processing Reduces Thickness, Changes Characteristics, and Improves Dissolution Profile.

Swallowing oral solid dosage forms is challenging for those who have medication swallowing difficulties, including patients with dysphagia. One option is to mix the drug (whole or crushed) with a thick vehicle (medication lubricant). Previous in vitro studies consistently suggest that thick vehicles could impact the dissolution of solid dosage forms, potentially influencing their therapeutic effectiveness, but do not account for changes that happen during oral processing and swallowing.

Evaluating the implementation of a prescription only regulatory model for nicotine vaping products: A qualitative study on the experiences and views of healthcare professionals.

Background: Deciding how to regulate nicotine vaping products (NVPs) is a challenge for many countries. Balanced regulation should consider the potential harms to young people from uptake of NVPs alongside the possible benefits of NVPs as a smoking cessation aid. One option is to make NVPs only available via medical prescription to adults who smoke.

Effects of a prebiotic formulation on the composition of the faecal microbiota of people with functional constipation.

Purpose: Prebiotics are defined as substances which selectively promote beneficial gut microbes leading to a health benefit for the host. Limited trials have been carried out investigating their effect on the microbiota composition of individuals afflicted by functional constipation with equivocal outcomes. In a 21-day randomised, controlled clinical trial involving 61 adults with functional constipation, a prebiotic formulation with partially hydrolysed guar gum and acacia gum as its main ingredients, significantly increased complete spontaneous bowel motions in the treatment group.

The prevalence and perceived effectiveness of using a medication-swallowing lubricant in aged care facilities across Australia.

Objective: To explore the extent of use and perceived effectiveness of using a medication lubricant that is specifically designed to help people who struggle to swallow their solid medications whole.

Method: Health care workers of varying professional levels in aged care facilities (ACFs) across Australia who are involved in medication administration were invited to participate in a structured online survey.

Results: Of the 355 health care workers who completed the survey, 48% had used the medication lubricant to aid administration of whole and/or crushed solid oral dosage forms, and of these 89% agreed with the statement that "it is effective method to facilitate medication swallowing in residents.

Autonomous action and cooperativity between the ONECUT2 transcription factor and its 3' untranslated region.

The transcription factor ONECUT2 (OC2) is a master transcriptional regulator operating in metastatic castration-resistant prostate cancer that suppresses androgen receptor activity and promotes neural differentiation and tumor cell survival. OC2 mRNA possesses an unusually long (14,575 nt), evolutionarily conserved 3' untranslated region (3' UTR) with many microRNA binding sites, including up to 26 miR-9 sites. This is notable because miR-9 targets many of the same genes regulated by the OC2 protein.

Diverse organic-mineral associations in Jezero crater, Mars.

The presence and distribution of preserved organic matter on the surface of Mars can provide key information about the Martian carbon cycle and the potential of the planet to host life throughout its history. Several types of organic molecules have been previously detected in Martian meteorites and at Gale crater, Mars. Evaluating the diversity and detectability of organic matter elsewhere on Mars is important for understanding the extent and diversity of Martian surface processes and the potential availability of carbon sources.
