PURPOSE Hemophilic arthropathy is a debilitating condition characterized by recurrent hemarthroses, leading to severe joint pain and eventual need for total knee arthroplasty (TKA). Postoperative pain management in this population is highly complex as the result of inherent bleeding risks, intense perioperative anxiety, and a frequently observed "pain-fear-immobility" cycle. The growing need...
Persistent debate surrounds whether the frontal lobe supports the emergence or reporting of consciousness, raising the hypothesis that distinct frontal subregions may support these processes. We addressed this by combining electroencephalography (EEG) with eye-tracking in Report and No-Report paradigms. Eye-movement features distinguished conscious and unconscious trials in the no-report task....
As the pace of modern life continues to accelerate, the pressure participants face is growing, and mental health issues are becoming increasingly prominent. Against this backdrop, meditation, as a proven method for stress relief and relaxation, has garnered widespread attention. However, many people face challenges during meditation, such as difficulty entering a meditative state quickly or...
To evaluate the effects of mindfulness meditation combined with eCASH-based nursing on perioperative pain and early recovery in patients with preeclampsia undergoing cesarean section. This retrospective study included 107 patients with preeclampsia who underwent cesarean section. According to the perioperative nursing intervention received, patients were assigned to a control group (n=53,...
Intraoperative low-dose esketamine failed to further improve the QoR-40 score after gynecologic malignancy laparotomy when used as part of a multimodal analgesic regimen. Further research is needed to explore the optimal dosage and indications of esketamine in this patient population.
Mindfulness, rooted in ancient meditation practices, emphasizes present-moment awareness and non-judgmental acceptance of sensations and thoughts. While traditionally practiced through face-to-face or self-guided methods, virtual reality(VR) offers a transformative platform to enhance mindfulness through immersive, multisensory experiences. This study investigates the impact of multimodal...
Prenatal stress exerts long-term impact on neurodevelopment in the offspring, with consequences such as increasing the offspring's risk of depression in adolescence and early adulthood. S-ketamine can produce rapid and robust antidepressant effects, but it is not clear yet whether and how S-ketamine alleviates depression in prenatally stressed offspring. The current study incestigated the...
To examine the dose-response effect of mindfulness-based cognitive therapy (MBCT) for college students with major depressive disorder (MDD), a randomized control trial with MBCT and a wait-list (WL) group was performed. All participants were invited to self-administer a set of questionnaires at baseline, mid-intervention (4th week), and post-intervention (8th week) by the 9-item Patient Health...
The discrepancy between the short half-life of ketamine and its long-lasting effects is due to ketamine being trapped in NMDA receptors, and its release depends on neural activity in the lateral habenula. Ketamine, an N -methyl- d -aspartate receptor (NMDAR) antagonist^ 1 , has revolutionized the treatment of depression because of its potent, rapid and sustained antidepressant effects^ 2 – 4 ....
Nitrous oxide (N2O) has demonstrated an antidepressant effect for treatment-resistant depression (TRD), but no studies investigated the effects of N2O on different cognition domains. This study aimed to test whether N2O would display pro-cognitive effects. We conducted a double-blinded, placebo-controlled, randomized controlled trial, 44 patients with TRD were randomized to N2O group (one-hour...
Background: Nursing students face unique academic and clinical workloads linked to increased stress. Previous studies indicate formal and informal mindfulness meditation provide stress-reducing benefits. This practice aligns with holistic nursing core values of self-care and self-reflection; little is known about meditation practice in nursing students. Objectives: Our study aimed to describe...
Youth depression is often associated with impairments in cognitive function, especially in executive function. This study examines the effect of an 8-session-long mindfulness training that can improve executive function in youth with depression. Sixty youths (age range 15-27 years) with depression were selected as participants and were randomized into a mindfulness training group (MTG) and a...
Nitrous oxide has rapid antidepressant effects in patients with treatment-resistant depression (TRD), but its underlying mechanisms of therapeutic actions are not well understood. Moreover, most of the current studies lack objective biological indicators to evaluate the changes of nitrous oxide-induced brain function for TRD. Therefore, this study assessed the effect of nitrous oxide on brain...
Nitrous oxide (N2O), an N-methyl-D-aspartate glutamate receptor antagonist, has demonstrated a rapid-onset antidepressant effect for treatment-resistant depression (TRD) preliminarily in the United States. This study aimed to test the efficacy and safety of N2O for TRD patients in China. In this double-blinded, placebo-controlled trial, 44 patients with TRD were randomized to receive a one-hour...
Selective kappa opioid receptor (KOR) agonists are promising antipruritic agents and analgesics. However, clinical development of KOR agonists has been limited by side effects, including psychotomimetic effects, dysphoria, and sedation, except for nalfurafine, and recently. CR845 (difelikefalin). Activation of KOR elicits G protein- and β-arrestin-mediated signaling. KOR-induced analgesic and...
Deficits in olfactory abilities are frequently observed in schizophrenia patients. However, whether olfactory dysfunction is found in animal models is not known. Here, we examined whether two well-established schizophrenia rat models exhibit olfactory-relevant dysfunction that is similar to schizophrenia patients. Olfactory sensitivity was tested in rats that were acutely (3.3mg/kg) or...
Emerging evidence suggests substantial health benefits from using meditation. While there are some indications that the popularity of meditation is increasing, little is known about the prevalence, patterns, and predictors of meditation use in the general population. In this secondary analysis of data from the 2012 US National Health Interview Survey (NHIS) (n = 34,525), lifetime and 12-month...
Amino-acid neurotransmitter system dysfunction plays a major role in the pathophysiology of major depressive disorder (MDD). We used proton magnetic resonance spectroscopy (¹H-MRS) to investigate whether prefrontal levels of amino-acid neurotransmitters predict antidepressant response to a single intravenous infusion of the N-methyl-D-aspartate (NMDA) antagonist ketamine in MDD patients....
