Objective: Accumulation of hydrophobic bile acids is linked with cancer development. However, derivatives of deoxycholic acid (DCA) and lithocholic acid (LCA) produced via bacterial metabolism may mitigate the proinflammatory and cytotoxic effects of hydrophobic bile acids. The impact of diet on secondary bile acid (BA) derivative production has not been determined.

Article Synopsis
  • Acute stress affects how we remember not just individual emotional events but also the contextual details surrounding them, with distinct neural processes involved for each type of memory.
  • Stressed participants showed increased brain activation in areas linked to item memory retrieval, but reduced activation for recalling unpleasant contextual details.
  • These findings highlight how stress can alter memory processing in different ways, suggesting potential implications for understanding stress-related disorders.

Article Synopsis
  • Anxiety disorders impact brain connectivity, but how this varies among different types of anxiety disorders (like panic disorder and social anxiety disorder) isn't fully understood due to limited studies.
  • Researchers examined the brain connectivity of 439 anxiety disorder patients and 105 healthy controls using resting-state fMRI, finding notable differences in connectivity patterns, especially in panic disorder and agoraphobia patients.
  • The study revealed that panic disorder patients had increased connectivity in brain regions linked to emotion regulation, unlike those with social anxiety disorder or specific phobia, suggesting the potential for personalized treatment approaches based on these neurological differences.

Rapid surface and subsurface changes in the Arctic polygonal tundra landscapes due to the melting of ice wedges, known as thermokarst processes, have significant implications for Arctic ecosystems. However, the integration of thermokarst processes into widely used global climate models for projections poses an important question. Here we use an integrated permafrost thermal hydrology model to explore the decoupled nature of two thermokarst processes - microtopography evolution and ground subsidence - in six Arctic locations.

Background: Individuals with anxiety disorders (ADs) often display hypervigilance to threat information, although this response may be less pronounced following psychotherapy. This study aims to investigate the unconscious recognition performance of facial expressions in patients with panic disorder (PD) post-treatment, shedding light on alterations in their emotional processing biases.

Methods: Patients with PD (n=34) after (exposure-based) cognitive behavior therapy and healthy controls (n=43) performed a subliminal affective recognition task.

Article Synopsis
  • - The ENIGMA Anxiety Working Group studied brain structural differences between individuals with specific phobias and healthy participants, focusing on subtypes of phobias like animal and blood-injection-injury (BII) while examining how these differences relate to symptom severity and age.
  • - A total of 1,452 participants with phobias and 2,991 healthy subjects were analyzed, revealing that those with phobias exhibited smaller subcortical volumes and varying cortical thickness, especially noted in adults rather than youths.
  • - The results indicate that brain alterations in specific phobias are more significant than in other anxiety disorders, revealing distinct neural underpinnings linked to fear processing across different phobia types, highlighting a

Together with warming air temperatures, Arctic ecosystems are expected to experience increases in heavy rainfall events. Recent studies report accelerated degradation of permafrost under heavy rainfall, which could put significant amounts of soil carbon and infrastructure at risk. However, controlled experimental evidence of rainfall effects on permafrost thaw is scarce.

Early-onset colorectal cancer (EOCRC) is defined as a diagnosis of colorectal cancer (CRC) in individuals younger than 50 years of age. While overall CRC rates in the United States (US) decreased between 2001 and 2018, EOCRC rates have increased. This research project aims to evaluate the feasibility and acceptability of Time-Restricted Eating (TRE), Mindfulness, or TRE combined with Mindfulness among young to middle-aged adults at risk of EOCRC.

Article Synopsis
  • Exposure-based cognitive-behavioral therapy has been shown to effectively treat anxiety disorders, but its impact on daily behaviors like social and physical activity had not been widely researched.
  • In a study involving 126 participants, including individuals with anxiety disorders and healthy controls, researchers tracked activities, social interactions, mood, and physical symptoms before, during, and after therapy using smartphones and motion sensors.
  • The findings revealed that therapy led to improvements in mood, social interactions, and physical activity levels, particularly in patients with initial higher depression scores, suggesting that this treatment could enhance overall daily functioning and reduce the risk of relapse.*

Article Synopsis
  • Theoretical perspectives in the affective sciences have increased in variety rather than converging due to differing beliefs about the nature and function of human emotions.
  • A teleological principle is proposed to create a unified approach by viewing human affective phenomena as algorithms that adapt to comfort or monitor these adaptations.
  • This framework aims to organize existing theories and inspire new research in the field, leading to a more integrated understanding of human affectivity through the concept of the Human Affectome.

Background: A direct comparison of the cost-benefit analysis of retroperitoneoscopic adrenalectomy (RPA) versus the minimally invasive transperitoneal access (LTA) approach is currently lacking. We hypothesized that RPA is more cost effective than LTA; promising significant savings for the healthcare system in an era of ever more limited resources.

Methods: We performed a monocentric retrospective observational cohort study based on data from our Endocrine Surgery Registry.

The startle response is a cross-species defensive reflex that is considered a key tool for cross-species translational emotion research. While the neural pathway mediating (affective) startle modulation has been extensively studied in rodents, human work on brain-behavior interactions has lagged in the past due to technical challenges, which have only recently been overcome through non-invasive simultaneous EMG-fMRI assessments. We illustrate key paradigms and methodological tools for startle response assessment in rodents and humans and review evidence for primary and modulatory neural circuits underlying startle responses and their affective modulation in humans.

Permafrost thaw can cause an intensification of climate change through the release of carbon as greenhouse gases. While the effect of air temperature on permafrost thaw is well quantified, the effect of rainfall is highly variable and not well understood. Here, we provide a literature review of studies reporting on effects of rainfall on ground temperatures in permafrost environments and use a numerical model to explore the underlying physical mechanisms under different climatic conditions.
