Camera traps are widely used in wildlife research and monitoring, so it is imperative to understand their strengths, limitations, and potential for increasing impact. We investigated a decade of use of wildlife cameras (2012-2022) with a case study on Australian terrestrial vertebrates using a multifaceted approach. We (i) synthesised information from a literature review; (ii) conducted an online questionnaire of 132 professionals; (iii) hosted an in-person workshop of 28 leading experts representing academia, non-governmental organisations (NGOs), and government; and (iv) mapped camera trap usage based on all sources.

Objective: Cannabis has become more available in Canada since its legalization in 2018. Many individuals who use cannabis also use alcohol (co-use), which can be used either at the same time such that their effects overlap (simultaneous use) or at different times (concurrent use). Though studies have identified predictors of co-use relative to single-substance use, less is known about the predictors of specific types of co-use.

Comprehensive global proteome profiling that is amenable to high throughput processing will broaden our understanding of complex biological systems. Here, we evaluated two leading mass spectrometry techniques, Data Independent Acquisition (DIA) and Tandem Mass Tagging (TMT), for extensive protein abundance profiling. DIA provides label-free quantification with a broad dynamic range, while TMT enables multiplexed analysis using isobaric tags for efficient cross-sample comparisons.

Several transcription inhibitors have been developed as cancer therapies. However, they show modest clinical activity, highlighting that our understanding of the cellular response to transcriptional inhibition remains incomplete. Here we report that potent inhibitors of transcription not only impact mRNA output but also markedly impair mRNA transcript localization and nuclear export.

The concordance between paraphilic interest and behavior is moderate to strong in previous studies. In the present study, we examined whether sexual excitation (SE) and sexual inhibition (SI) moderate the concordance between paraphilic interest and behavior, across several paraphilic themes. We expected that stronger concordance would be found at high levels of SE and weaker concordance would be found at high levels of SI, for both men and women.

We present results from a complete next-to-leading order (NLO) calculation of e^{+}e^{-}→ZH in the standard model effective field theory (SMEFT) framework, including all contributions from dimension-six operators. At NLO, there are novel dependencies on CP violating parameters in the gauge sector, on modifications to the Higgs boson self-couplings, on alterations to the top quark Yukawa couplings, and on four-fermion operators involving the electron and the top quark, among others. We show that including only the logarithms resulting from renormalization group scaling can produce misleading results, and further, we explicitly demonstrate the constraining power of combining measurements from different energy scales.

Objectives: This scoping review was undertaken to identify risk predictions models and preoperative predictors of surgical site infection (SSI) in adult cardiac surgery. A particular focus was on the identification of novel predictors that could underpin the future development of a risk prediction model to identify individuals at high-risk of SSI, and therefore guide a national SSI prevention strategy.

Methods: A scoping review to systematically identify and map out existing research evidence on preoperative predictors of SSI was conducted in two stages.

Background: Machine Learning (ML) models have been used to predict common mental disorders (CMDs) and may provide insights into the key modifiable factors that can identify and predict CMD risk and be targeted through interventions. This systematic review aimed to synthesise evidence from ML studies predicting CMDs, evaluate their performance, and establish the potential benefit of incorporating lifestyle data in ML models alongside biological and/or demographic-environmental factors.

Methods: This systematic review adheres to the PRISMA statement (Prospero CRD42023401194).

Background: The prenatal and early-life periods pose a crucial neurodevelopmental window whereby disruptions to the intestinal microbiota and the developing brain may have adverse impacts. As antibiotics affect the human intestinal microbiome, it follows that early-life antibiotic exposure may be associated with later-life psychiatric or neurocognitive outcomes.

Aims: To explore the association between early-life (in utero and early childhood (age 0-2 years)) antibiotic exposure and the subsequent risk of psychiatric and neurocognitive outcomes.

Introduction: There are many recognised benefits of public involvement, including more relevant research. The COVID-19 pandemic highlighted the existing health inequalities and disparities in access to care and treatment for under-served groups, necessitating meaningful and sustainable approaches to engaging them in health research. However, there is limited guidance to suggest what groundwork and processes are necessary for initiating such projects.

While HIV infection and clonal hematopoiesis (CH) have been linked with inflammatory dysregulation and an increased risk of aging-related comorbidities, their relationship with clinical geriatric syndromes has not been well defined. In the Age-related Clonal Haematopoiesis in an HIV Evaluation Cohort (ARCHIVE) study (NCT04641013), we measure associations between HIV and CH and geriatric syndromes. Of 345 participants (176 with HIV and 169 without HIV), 23% had at least one mutation associated with CH: 27% with HIV and 18% without HIV (p = 0.

Article Synopsis
  • This text discusses the role of social prescribing in connecting older people from ethnic minority groups to cultural offerings that can help address issues like loneliness and poor mental health.
  • A scoping review was conducted to analyze existing literature on how cultural activities are tailored for these older populations in the UK, resulting in six key sources that highlight both opportunities and barriers to engagement.
  • The findings suggest that consulting with the target groups is crucial for creating inclusive activities and emphasize the need for more research in this area, as cultural providers currently lack sufficient evidence to effectively develop their offerings.

Background: Hand hygiene (HH) is an essential element of infection prevention and control programs. Direct observation of adherence to the 5 moments for HH is considered the gold standard in compliance monitoring. However, as direct observation introduces potential bias, other strategies have been proposed to supplement HH compliance data in healthcare facilities.

One of the most common reported postpartum concerns, linked with relationship dissatisfaction, is how body image will affect sexuality. Outside of the postpartum period, feeling more satisfied with one's body is linked with feeling more sexually and relationally satisfied, with some cross-sectional evidence that sexual satisfaction mediates these associations. This dyadic daily experience study examined how new parents' daily satisfaction with their own and their partner's bodies relates to their own sexual satisfaction, and in turn, their own and their partner's relationship satisfaction during a vulnerable time in their sexual and romantic relationship-3- to 4-months postpartum.

The use of circulating tumour DNA (ctDNA) to profile mutational signatures represents a non-invasive opportunity for understanding cancer mutational processes. Here we present MisMatchFinder, a liquid biopsy approach for mutational signature detection using low-coverage whole-genome sequencing of ctDNA. Through analysis of 375 plasma samples across 9 cancers, we demonstrate that MisMatchFinder accurately infers single-base and doublet-base substitutions, as well as insertions and deletions to enhance the detection of ctDNA and clinically relevant mutational signatures.

Objectives: Intimate partner violence (IPV) has short- and long-term health effects, including physical injuries and traumatic brain injury, as well as sexual, reproductive, and mental health issues. However, accessing necessary health care is often challenging for IPV survivors and became even more difficult during the COVID-19 pandemic. We examined access to health care among those affected by IPV during the COVID-19 pandemic to better connect survivors to health and social support services.

Objectives: In experimental models, the prenatal diet influences gut microbiota composition in mothers and offspring; however, it is unclear whether this occurs in humans. We investigated the effects of a gut-focused perinatal dietary intervention on maternal and infant gut microbiota composition four weeks after birth.

Methods: This randomised controlled trial randomised pregnant women to receive dietary advice as part of standard care, or additionally receive a dietary intervention focused on the Australian Dietary Guidelines and increasing prebiotic and probiotic/fermented food intakes (ACTRN12616000936426).
