Does screening for maternal ACEs in prenatal care predict pregnancy health risk above and beyond demographic and routine mental health screening?

Background: Adverse childhood experiences (ACEs), including abuse, neglect, and/or household dysfunction, are associated with physical and mental health difficulties in pregnancy and the postpartum period. These associations have prompted the adoption of screening for ACEs in prenatal care settings; however, little is known about whether asking about ACEs in the prenatal care context is additive to other forms of routine prenatal demographic and mental health screening.

Objective: To identify whether ACEs are predictive of cumulative pregnancy health risk and identify whether ACEs predict maternal health risks in pregnancy above and beyond screening for financial stress, depression, and anxiety.

Obesity-induced astrocyte dysfunction impairs heterosynaptic plasticity in the orbitofrontal cortex.

Overconsumption of highly palatable, energy-dense food is considered a key driver of the obesity pandemic. The orbitofrontal cortex (OFC) is critical for reward valuation of gustatory signals, yet how the OFC adapts to obesogenic diets is poorly understood. Here, we show that extended access to a cafeteria diet impairs astrocyte glutamate clearance, which leads to a heterosynaptic depression of GABA transmission onto pyramidal neurons of the OFC.

Opioid use disorder treatment disruptions during the early COVID-19 pandemic and other emergent disasters: a scoping review addressing dual public health emergencies.

Background: During public health emergencies, people with opioid use disorder (PWOUD) may be particularly impacted. Emergent disasters such as the COVID-19 pandemic disrupt already-strained harm reduction efforts and treatment availability. This study aims to answer three research questions.

Non-pharmacologic interventions to treat apathy in Parkinson's disease: A realist review.

Introduction: There is a diverse body of evidence investigating non-pharmacological treatment options for apathy in Parkinson's disease (PD). We aimed to better understand the context and mechanisms by which non-pharmacological interventions may improve apathy in persons with PD.

Methods: We conducted a realist review of the body of evidence investigating treatment options for apathy in PD.

Nurse-Led Care for Stable Patients with Rheumatoid Arthritis: Quality of Care in Routine Practice Compared to the Traditional Rheumatologist-Led Model.

Introduction: This pragmatic non-inferiority study assessed quality of care within a nurse-led care (NLC) model for stable patients with rheumatoid arthritis (RA) compared to the traditional rheumatologist-led care (RLC) model.

Methods: Data were collected through a chart review. Baseline demographic and clinical characteristics were compared using Chi-square test and t test.

From Pathways to Practice: Impact of Implementing Mobilization Recommendations in Head and Neck Cancer Surgery with Free Flap Reconstruction.

One of the foundational elements of enhanced recovery after surgery (ERAS) guidelines is early postoperative mobilization. For patients undergoing head and neck cancer (HNC) surgery with free flap reconstruction, the ERAS guideline recommends patients be mobilized within 24 h postoperatively. The objective of this study was to evaluate compliance with the ERAS recommendation for early postoperative mobilization in 445 consecutive patients who underwent HNC surgery in the Calgary Head and Neck Enhanced Recovery Program.

Impact of Early Mobilization on Recovery after Major Head and Neck Surgery with Free Flap Reconstruction.

Surgery with free flap reconstruction is a standard treatment for head and neck cancer (HNC). Because of the complexity of HNC surgery, recovery can be challenging, and complications are common. One of the foundations of enhanced recovery after surgery (ERAS) is early postoperative mobilization.

Laboratory reporting of framingham risk score increases statin prescriptions in at-risk patients.

Background: The under-utilization of cardiovascular preventative therapy with statins warrants novel interventions to optimize prescriptions in at-risk patients. We investigated the role of a laboratory generated Framingham Risk Score (FRS) provided to primary care clinicians in changing statin use in a primary care setting.

Methods: Data was acquired from the electronic medical records of 1573 anonymized patients undergoing routine lipid testing.

Social functioning and brain imaging in individuals at clinical high-risk for psychosis: A systematic review.

Impairments in social functioning are a core impairment in psychosis and are associated with poor outcomes. These deficits are found in those at clinical high-risk (CHR) for psychosis, and can persist even in the absence of transition. However, the neurobiological underpinnings of social functioning remain unclear, therefore we conducted a systematic review of brain metrics that have been associated with social functioning in youth at CHR for psychosis.

Systematic review: cystic fibrosis in the SARS-CoV-2/COVID-19 pandemic.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and the development of life-threatening COVID-19 are believed to disproportionately affect certain at-risk populations. However, it is not clear whether individuals with cystic fibrosis (CF) are at a higher risk of COVID-19 or its adverse consequences. Recurrent respiratory viral infections are often associated with perturbation and pulmonary exacerbations of CF as evidenced by the significant morbidity observed in CF individuals during the 2009 H1N1 pandemic.

Body mass estimation from footprint size in hominins.

Although many studies relating stature to foot length have been carried out, the relationship between foot size and body mass remains poorly understood. Here we investigate this relationship in 193 adult and 50 juvenile habitually unshod/minimally shod individuals from five different populations-Machiguenga, Daasanach, Pumé, Hadzabe, and Samoans-varying greatly in body size and shape. Body mass is highly correlated with foot size, and can be predicted from foot area (maximum length × breadth) in the combined sample with an average error of about 10%.

Maintained Bone Density in Young Hypoestrogenized Women with a High BMI: Case Series.

Estrogen deficiency and obesity are factors that affect bone mass in a manner that is independent and in opposing directions. Obesity favours higher bone mass and increased bone formation whereas estrogen deficiency leads to significant bone loss in leaner individuals. To report the impact of the competing effects of a hypoestrogenized state and obesity on long-term bone health, we present two cases of young chronically hypoestrogenized females whose bone parameters were assessed with high-resolution peripheral quantitative computed tomography (HR-pQCT) and revealed a bone mineral density and microstructure that did not change despite the long history of a low estrogen state.

What can we teach Lymnaea and what can Lymnaea teach us?

This review describes the advantages of adopting a molluscan complementary model, the freshwater snail Lymnaea stagnalis, to study the neural basis of learning and memory in appetitive and avoidance classical conditioning; as well as operant conditioning of its aerial respiratory and escape behaviour. We firstly explored 'what we can teach Lymnaea' by discussing a variety of sensitive, solid, easily reproducible and simple behavioural tests that have been used to uncover the memory abilities of this model system. Answering this question will allow us to open new frontiers in neuroscience and behavioural research to enhance our understanding of how the nervous system mediates learning and memory.

TRPV1 Activation Promotes β-arrestin2 Interaction with the Ribosomal Biogenesis Machinery in the Nucleolus:Implications for p53 Regulation and Neurite Outgrowth.

Transient receptor potential vanilloids TRPV1) are non-selective cation channels that sense and transduce inflammatory pain signals. We previously reported that activation of TRPV1 induced the translocation of β-arrestin2 (ARRB2) from the cytoplasm to the nucleus, raising questions about the functional role of ARRB2 in the nucleus. Here, we determined the ARRB2 nuclear signalosome by conducting a quantitative proteomic analysis of the nucleus-sequestered L395Q ARRB2 mutant, compared to the cytosolic wild-type ARRB2 (WT ARRB2), in a heterologous expression system.

Participant-reported effect of an Indigenous health continuing professional development initiative for specialists.

Background: Health outcomes of Indigenous patients are impacted by culturally unsafe specialty care environments. The 'Educating for Equity (E4E)' program is a continuing professional development (CPD) intervention which incorporates skill-based teaching to improve Indigenous patient experiences and outcomes in healthcare interactions.

Methods: The E4E program was delivered to rheumatologists in two phases, each delivered as experiential learning workshops where participants engaged with and applied course content within an interactive format focusing on real-time feedback.

The effectiveness of a men-only supportive expressive group therapy intervention for psychosocial health outcomes in gastrointestinal cancer patients: a 6-month longitudinal study.

Background: An increasing number of gastrointestinal cancer (GI) patients suffer from side effects of cancer treatment that can affect their mood states and quality of life. Despite its demonstrated effectiveness in female cancer patients, Supportive Expressive Group Therapy (SEGT) has not been tested in male cancer patients. The current study sought to examine the longitudinal effects of a professionally-led, men-only SEGT on mood states, coping, and quality of life (QoL) in male GI cancer patients.

Temporo-Frontal Coherences and High-Frequency iEEG Responses during Spatial Navigation in Patients with Drug-Resistant Epilepsy.

The prefrontal cortex and hippocampus function in tight coordination during multiple cognitive processes. During spatial navigation, prefrontal neurons are linked to hippocampal theta oscillations, presumably in order to enhance communication. Hippocampal ripples have been suggested to reflect spatial memory processes.

Overcoming bioprocess bottlenecks in the large-scale expansion of high-quality hiPSC aggregates in vertical-wheel stirred suspension bioreactors.

Background: Human induced pluripotent stem cells (hiPSCs) hold enormous promise in accelerating breakthroughs in understanding human development, drug screening, disease modeling, and cell and gene therapies. Their potential, however, has been bottlenecked in a mostly laboratory setting due to bioprocess challenges in the scale-up of large quantities of high-quality cells for clinical and manufacturing purposes. While several studies have investigated the production of hiPSCs in bioreactors, the use of conventional horizontal-impeller, paddle, and rocking-wave mixing mechanisms have demonstrated unfavorable hydrodynamic environments for hiPSC growth and quality maintenance.

Adverse childhood experiences and health among indigenous persons experiencing homelessness.

Background: Current literature has established that adverse childhood experiences (ACEs) are associated with the onset of a variety of physical, mental, and behavioural illnesses. However, there are few studies that have thoroughly examined this association in low-income or marginalized groups.

Methods: To address this knowledge gap, this study used self-reported data on childhood experiences and adult health outcomes in a sample of 91 Indigenous persons experiencing homelessness.

LTD is involved in the formation and maintenance of rat hippocampal CA1 place-cell fields.

Hippocampal synaptic plasticity includes both long-term potentiation (LTP) and long-term depression (LTD) of synaptic strength, and has been implicated in shaping place field representations that form upon initial exposure to a novel environment. However, direct evidence causally linking either LTP or LTD to place fields remains limited. Here, we show that hippocampal LTD regulates the acute formation and maintenance of place fields using electrophysiology and blocking specifically LTD in freely-moving rats.

The Pharmacological TAILS of Matrix Metalloproteinases and Their Inhibitors.

Matrix metalloproteinases (MMPs) have been demonstrated to have both detrimental and protective functions in inflammatory diseases. Several MMP inhibitors, with the exception of Periostat, have failed in Phase III clinical trials. As an alternative strategy, recent efforts have been focussed on the development of more selective inhibitors or targeting other domains than their active sites through specific small molecule inhibitors or monoclonal antibodies.
