Previous research has shown that transcutaneous auricular vagus nerve stimulation (tVNS) promotes declarative fear extinction, but its neural mechanisms in this process are still unclear. This study aimed to explore tVNS's impacts on physiological (skin conductance response [SCR]) and neural (event-related potentials, ERP) fear-related responses. Forty healthy participants were randomly assigned to the tVNS or Sham group.

White matter tracts (WMTs), which mediate information transmission in the brain, are closely associated with the pathogenesis of psychiatric disorders, yet the causality of their associations remain unclear. Thus, we employed two-sample bidirectional Mendelian randomization to explore the causality between WMTs and 10 psychiatric disorders. We found that one standard deviation changes of WMTs metrics modified risks for 8 psychiatric disorders by 2·2% to 71·4%.

Backgrounds: Observational research has shown significant associations between inflammatory factors and sleep. Experimental studies suggested acute increase in the levels of inflammatory markers following sleep deprivation and sleep restriction. However, the causal association between inflammatory factors and sleep remains unclear in chronic and natural settings.

Heart failure, which is often the final stage of various cardiovascular diseases, remains a major cause of mortality, challenging the efficacy of current therapeutic advancements. Contemporary pharmacological treatments for heart failure aim to mitigate neurohormonal activation, alleviate volume overload, and provide inotropic support, particularly under conditions of hemodynamic instability. Despite these efforts and advancements in medications and medical technology, the mortality rates associated with heart failure continue to be alarmingly high.

Obstructive sleep apnea (OSA) and related hypoxia are well-established cardiovascular and neurocognitive risk factors. Current multi-sensor diagnostic approaches are intrusive and prone to misdiagnosis when simplified. This study introduces an enhanced single-sensor-based OSA screening method, leveraging novel signal processing and machine learning to ensure accurate detection across diverse populations.

Aims: Objective sleep parameters in patients with HF and their comorbidity with sleep-disordered breathing (SDB) are not fully understood. We aimed to investigate the polysomnography-measured sleep characteristics in HF patients using a systematic review and meta-analysis.

Methods: PubMed, Embase, and Web of Science databases were searched for studies on PSG in HF patients.

Objective: To investigate the causal association between insomnia and chronic kidney disease (CKD) and to explore the underlying protein pathways.

Methods: In primary analyses, multivariate regression and 1-sample mendelian randomization (1SMR) analyses were performed to estimate the associations between insomnia and CKD in the UK Biobank cohort. The study was conducted from March 13, 2006, to November 12, 2021.

Purpose: Previous studies support the causal effect of insomnia on heart failure. Fatty acid metabolism plays key roles in the occurrence and development of heart failure. It is unclear whether fatty acids play roles in the causal association between insomnia and heart failure.

Background: The study aimed to investigate whether the associations of accelerometer-measured physical activity (PA) and sedentary behaviour (SB) with incident chronic kidney disease (CKD) vary based on different levels of hand grip strength, identifying the modifying role of grip strength in these associations.

Methods: The study included 87 487 adults from the UK Biobank. PA and SB were quantified using accelerometers over 7-day period, while grip strength was assessed using a hand dynamometer.

Article Synopsis
  • The study investigates the genetic connection between depression (DEP) and obesity (BMI), finding a positive genetic correlation and shared genetic loci between the two conditions.
  • By analyzing a large dataset through various genetic methodologies, researchers identified 16 shared genetic loci, including newly discovered ones, indicating that both conditions can influence each other.
  • Gene expression analysis revealed that these genetic correlations are concentrated in specific brain regions and types of cells, with NEGR1 emerging as a key gene linked to both depression and obesity.

Loneliness-the subjective experience of social disconnection-is now widely regarded as a health risk factor. However, whether the associations between loneliness and multiple diseases are consistent with causal effects remains largely unexplored. Here we combined behavioural, genetic and hospitalization data from the UK Biobank to examine the associations of loneliness with a wide range of non-overlapping diseases.

Background: Physical activity (PA) is considered beneficial for lowering cardiovascular risks following type 2 diabetes mellitus (T2DM) and prediabetes, but existing evidence relies mainly on self-reported measurements. We aimed to describe the intensity-specific dose-response associations of PA and sedentary behavior (SB) with macrovascular and microvascular events among individuals with T2DM and prediabetes.

Methods: This study included 11,474 individuals with T2DM and prediabetes from the UK Biobank.

Study Objectives: Observational studies suggest associations between insomnia and cardiovascular diseases (CVDs), but the causal mechanism remains unclear. We investigated the potential causal associations between insomnia and CVDs by a combined systematic meta-review and meta-analysis of observational and Mendelian randomization studies.

Methods: We searched PubMed, Web of Science, and Embase for English-language articles from inception to July 11, 2023.

Article Synopsis
  • - This study examined the links between social isolation and loneliness with diabetic microvascular complications (DMCs) in individuals with type 2 diabetes, finding that both factors significantly increase the risk of conditions like diabetic kidney disease and neuropathy.
  • - Over 12.6 years, data showed that higher levels of social isolation correlated with a 13% increased risk for DMCs and loneliness also heightened risk, underscoring the importance of social connections alongside traditional diabetes risk factors like blood pressure and smoking.
  • - While the findings suggest strong associations, the results may not be universally applicable due to the specific demographics of the UK Biobank participants.

Emerging evidence has linked childhood maltreatment with cardiovascular disease risk; however, the association between childhood maltreatment and cardiac arrhythmias remains unclear. Moreover, any genetic predispositions to atrial fibrillation (AF), a common cardiac arrhythmia associated with an elevated risk of stroke, heart failure, and mortality, that modify such associations have been undocumented. To examine the associations between childhood maltreatment and incident arrhythmias, and whether a genetic predisposition to arrhythmias modifies these associations.

Article Synopsis
  • The study looked at how cost-effective a type of therapy called cognitive behavioral therapy for insomnia (CBTI) is for adults who have trouble sleeping, especially when done online (dCBTI).
  • Researchers checked different databases to find and analyze the results of 12 studies from 2004 to 2023 comparing CBTI with other treatments or no treatment at all.
  • They found that CBTI and dCBTI are cheaper and more effective than the other options, especially in the long run, and that dCBTI helps people save money related to work absences.
