Objective: Acceptance and commitment therapy (ACT) is a transdiagnostic, behavioral treatment focusing on common processes behind different diagnoses. Internet-based treatment programs can improve access to treatment and easily be integrated into the individual's life.
Method: This single-arm, pre-post-follow-up pilot study examined the acceptability, safety, and effectiveness of internet-based ACT (iACT) for participants with comorbid posttraumatic stress disorder (PTSD) and chronic pain treated at a tertiary pain clinic. All participants ( = 10) received the iACT program over a period of 10 weeks and were assessed pre- and postintervention and at a 3-month follow-up.
Results: This study provides preliminary evidence for the acceptability, safety, and effectiveness of iACT for comorbid PTSD and chronic pain. The program showed clinically significant improvement in relation to the primary outcomes PTSD symptom severity and pain interference for this patient group with complex, comorbid symptoms, with sustained effects at the 3-month follow-up.
Conclusions: These results add to previous research where face-to-face ACT has been shown to be of benefit to individuals with either chronic pain or PTSD. The findings also suggest that iACT can be delivered to individuals with comorbid PTSD and chronic pain with an effectiveness that is comparable to other cognitive behavioral therapy-based treatments for somatic and psychiatric disorders.

Background: Chronic pruritus is the defining symptom of atopic dermatitis (AD). Although AD is common in Latin America, there is little data regarding pruritus intensity, characteristics, and effects on quality of life in this population.
Objective: This cross-sectional study aimed to evaluate pruritus in 91 patients with AD at a tertiary university hospital in São Paulo, Brazil.

Sleep disorders refer to conditions characterized by abnormal sleep duration and quality, including insomnia, sleep-disordered breathing, and fragmented sleep, and have become one of the major challenges to modern physical and mental health. The anterior cingulate cortex (ACC) is an important component of the limbic system, located between the cingulate sulcus and the callosal sulcus on the medial surface of the cerebral hemispheres, and plays a critical role in regulating autonomic movements, emotions, and pain. It is an important part of the sleep regulation system.

Objectives: Sleep deprivation (SD) is a risk factor for the development of chronic pain in adolescents, significantly affecting pain management and prognosis; however, the mechanisms by which SD influences postoperative pain outcomes remain unclear. This study aims to investigate the molecular mechanism through which the spinal 5-hydroxytryptamine 1 receptor (5-HT1R) regulates the excitation/inhibition (E/I) balance in the dorsal horn to modulate postoperative chronic pain induced by SD in adolescent mice.

Chronic pain is a significant public health concern that diminishes patients' quality of life and imposes considerable socioeconomic costs. Effective pharmacological treatments for ongoing pain are limited. Recent studies have indicated that various models of chronic pain-such as neuropathic pain, inflammatory pain, and pain associated with cancer-have abnormal levels of long noncoding RNAs (lncRNAs).

To investigate the correlation between different prenatal imaging techniques in congenital diaphragmatic hernia (CDH) and their prognostic value.209 fetuses with CDH were enrolled in this retrospective cohort study. The prenatal ultrasound-based and MRI-based (MRI: magnetic resonance imaging) observed-to-expected lung-to-head ratio (o/e-LHR) and MRI-based relative fetal lung volume (rFLV) were evaluated and compared.
