Reference intervals of two-dimensional speckle tracking-derived endocardial global longitudinal strain analysis in 132 healthy cats.

Introduction: The assessment of left ventricular myocardial deformation and function by two-dimensional speckle tracking-derived strain analysis is an established method in human cardiology. It also progressively gains recognition in veterinary cardiology in both dogs and cats.

Objectives: The objectives of this study were to create reference intervals for two-dimensional speckle tracking echocardiography (STE)-derived endocardial global longitudinal strain (GLS) in a population of healthy adult cats of different breeds.

Ablation of CCL17-positive hippocampal neurons induces inflammation-dependent epilepsy.

Objective: Neuronal cell death and neuroinflammation are characteristic features of epilepsy, but it remains unclear whether neuronal cell death as such is causative for the development of epileptic seizures. To test this hypothesis, we established a novel mouse line permitting inducible ablation of pyramidal neurons by inserting simian diphtheria toxin (DT) receptor (DTR) cDNA into the Ccl17 locus. The chemokine CCL17 is expressed in pyramidal CA1 neurons in adult mice controlling microglial quiescence.

First Demonstration of PDE11A4 Target Engagement for Potential Treatment of Age-Related Memory Disorders.

PDE11A4 is a target of interest for the treatment of age-related memory disorders. A previous report from our laboratories described an amide series of potent, selective PDE11A4 inhibitors that was metabolically unstable. Investigation of heterocyclic amide isosteres for the labile amide moiety revealed distinct structure-activity relationships and identified several compounds with potency comparable to the amide series.

Quality of life for patients with advanced gastrointestinal cancer randomised to early specialised home-based palliative care: the ALLAN trial.

Background: The primary aim of specialised palliative care (SPC) is to improve the quality of life (QoL) for patients with a high symptom burden from a life-threatening disease. This randomised study aimed to assess the QoL impact of early integration of SPC alongside tumour-specific palliative treatment in patients with gastrointestinal (GI) cancers.

Methods: We randomly assigned ambulatory patients with advanced GI cancer to early integration of SPC and palliative tumour-specific treatment or tumour-specific treatment alone.

A Modified Switching Procedure from Temporary to Tunneled Central Venous Dialysis Catheters.

Tunneled central venous catheters are commonly used for dialysis in patients without a functional permanent vascular access. In an emergent setting, a non-tunneled, temporary central venous catheter is often placed for immediate dialysis. The most critical step in the catheter insertion is venipuncture, which is often a major cause for longer intervention times and procedure-related adverse events.

Association Between Autism and PTSD Among Adult Psychiatric Outpatients.

Purpose: Autism Spectrum Disorder (ASD) occurs in 1-1.5% of the general population and possibly in up to 20% of psychiatric outpatients. Post Traumatic Stress Disorder (PTSD) occurs at some point in life in 4% of the general population and in 14-20% of psychiatric outpatients.

Dynamics of virological and immunological markers of HIV persistence after allogeneic haematopoietic stem-cell transplantation in the IciStem cohort: a prospective observational cohort study.

Background: Allogeneic haematopoietic stem-cell transplantation (allo-HSCT) markedly reduces HIV reservoirs, but the mechanisms by which this occurs are only partly understood. In this study, we aimed to describe the dynamics of virological and immunological markers of HIV persistence after allo-HSCT.

Methods: In this prospective observational cohort study, we analysed the viral reservoir and serological dynamics in IciStem cohort participants with HIV who had undergone allo-HSCT and were receiving antiretroviral therapy, ten of whom had received cells from donors with the CCR5Δ32 mutation.

Influence of Season, Storage Temperature and Time of Sample Collection in Pancreatitis-Associated Protein-Based Algorithms for Newborn Screening for Cystic Fibrosis.

Newborn screening (NBS) for cystic fibrosis (CF) based on pancreatitis-associated protein (PAP) has been performed for several years. While some influencing factors are known, there is currently a lack of information on the influence of seasonal temperature on PAP determination or on the course of PAP blood concentration in infants during the first year of life. Using data from two PAP studies at the Heidelberg NBS centre and storage experiments, we compared PAP determinations in summer and winter and determined the direct influence of temperature.

Exploring the presence of oral bacteria in non-oral sites of patients with cardiovascular diseases using whole metagenomic data.

Cardiovascular diseases (CVDs) encompass various conditions affecting the heart and its blood vessels and are often linked with oral microbes. Our data analysis aimed to identify oral bacteria from other non-oral sites (i.e.

Trajectories of immune-related serum proteins and quality of life in patients with pancreatic and other periampullary cancer: the CHAMP study.

Background: There is still a profound lack of efficient therapeutic strategies against pancreatic and other periampullary adenocarcinoma. Surgery is seldom possible, leaving palliative chemotherapy the only option for most patients. Chemotherapy treatment is however often accompanied by serious side-effects, and the identification of biomarkers for early prediction of disease and treatment-associated symptoms could help alleviate patient suffering.

First Optimization of Novel, Potent, Selective PDE11A4 Inhibitors for Age-Related Cognitive Decline.

Phosphodiesterase 11A4 (PDE11A4) is a dual-acting cyclic nucleotide hydrolase expressed in neurons in the CA1, subiculum, amygdalostriatal transition area and amygdalohippocampal area of the extended hippocampal formation. PDE11A4 is the only PDE enzyme to emanate solely from hippocampal formation, a key brain region for the formation of long-term memory. PDE11A4 expression increases in the hippocampal formation of both humans and rodents as they age.

Identification of novel genetic risk factors of dilated cardiomyopathy: from canine to human.

Background: Dilated cardiomyopathy (DCM) is a life-threatening heart disease and a common cause of heart failure due to systolic dysfunction and subsequent left or biventricular dilatation. A significant number of cases have a genetic etiology; however, as a complex disease, the exact genetic risk factors are largely unknown, and many patients remain without a molecular diagnosis.

Methods: We performed GWAS followed by whole-genome, transcriptome, and immunohistochemical analyses in a spontaneously occurring canine model of DCM.

Comparison of Tumour-Specific Phenotypes in Human Primary and Expandable Pancreatic Cancer Cell Lines.

There is an ongoing need for patient-specific chemotherapy for pancreatic cancer. Tumour cells isolated from human tissues can be used to predict patients' response to chemotherapy. However, the isolation and maintenance of pancreatic cancer cells is challenging because these cells become highly vulnerable after losing the tumour microenvironment.

Sex-specific differences and similarities of olanzapine and risperidone on avoidance suppression in rats in the conditioned avoidance response test.

It is well known that antipsychotic drugs (APDs) are more effective in reducing symptoms in women than in men, and that women are more sensitive to the side effects of APDs. Therefore, it is of great importance that sex differences in drug responses are considered already in the early stages of drug development. In this study, we investigated whether sex-specific differences could be observed in response to the commonly prescribed APDs olanzapine and risperidone using the conditioned avoidance response (CAR) test.

Oral health literacy, knowledge and perceptions in a socially and culturally diverse population: a mixed methods study.

Background: Poor oral health literacy has been proposed as a causal factor in disparities in oral health outcomes. This study aims to investigate oral health literacy (OHL) in a socially and culturally diverse population of Australian adults visiting a public dental clinic in Western Sydney.

Methods: A mixed methods study where oral health literacy was assessed using the Health Literacy in Dentistry scale (HeLD-14) questionnaire and semi-structured interviews explored oral health related knowledge, perceptions and attitudes.

Oral health status and risk of incident diabetes: A prospective cohort study of 213,389 individuals aged 45 and over.

Aims: To examine whether simple measures of oral health are associated with incident diabetes.

Methods: This prospective cohort study linked data from the 45 and Up Study, Australia, to administrative health records. The study participants were 213,389 men and women, aged ≥45 years, with no diabetes at baseline.

Economic impact of reducing treatment gaps in depression.

Background: Major depressive disorder (MDD) is highly prevalent across Europe. While evidence-based treatments exist, many people with MDD have their condition undetected and/or untreated. This study aimed to assess the cost-effectiveness of reducing treatment gaps using a modeling approach.

The 'lost generation' in adult psychiatry: psychiatric, neurodevelopmental and sociodemographic characteristics of psychiatric patients with autism unrecognised in childhood.

Background: Patients with 'underlying' autism spectrum disorder (ASD) constitute a significant minority in adult out-patient psychiatry. Diagnoses of previously unrecognised ASD are increasing in adults. Characteristics of patients with autism within adult out-patient psychiatry have not been sufficiently explored, and there have not been any systematic comparisons of characteristics between patients with and those without autism within adult out-patient psychiatric populations.
