Patients’ Perspectives on How to Improve Endometriosis Care: A Large Qualitative Study Within the ComPaRe-Endometriosis e-Cohort.

Endometriosis is a chronic gynecological condition that affects about 10% of women of reproductive age. Despite its prevalence, diagnosis is often delayed, misdiagnosis is common, and treatment options are poor. This study aimed at capturing ideas to improve endometriosis care from the patients' perspectives. We analyzed cross-sectional data from 1,000 adult patients in ComPaRe-Endometriosis (a French prospective e-cohort focused on endometriosis) who answered to the open-ended question: "If you had a magic wand, what would you change about your health care?". The free-text responses were analyzed by qualitative thematic analysis using an inductive approach. Patients had a mean age of 34.1 years (standard deviation = 8.1); 56% and 42% had stage IV disease or deep endometriosis, respectively. They elicited 2,487 ideas to improve the management of endometriosis, which were categorized into 61 areas of improvement, further grouped into 14 themes. The top five areas of improvement were mentioned by >10% of the patients and were to (1) train caregivers to develop their knowledge on the disease, (2) provide better management of daily pain and pain attacks, (3) take patient-reported symptoms seriously, (4) standardize diagnostic processes to improve early detection, and (5) have caregivers listen more to the patients. We identified 61 areas for improvement in endometriosis care. These results reflect patients' expectations in terms of management of their disease and will be useful to design a better global care for endometriosis from the patients' perspectives.

Developing multivariable models for predicting headache improvement in patients with acute post-traumatic headache attributed to mild traumatic brain injury: A preliminary study.

Post-traumatic headache (PTH) is a common symptom after mild traumatic brain injury (mTBI). Although there have been several studies that have used clinical features of PTH to attempt to predict headache recovery, currently no accurate methods exist for predicting individuals' improvement from acute PTH. This study investigated the utility of clinical questionnaires for predicting (i) headache improvement at 3 and 6 months, and (ii) headache trajectories over the first 3 months.

Equity Reporting in Systematic Reviews of Opioid Treatment of Chronic Non-Cancer Pain with Patient-Reported Outcomes.

Chronic non-cancer pain can affect a patient's social life, ability to work, and overall quality of life (QoL). Opioid therapy is often prescribed as therapeutic treatment in chronic pain. Systematic reviews (SRs)-the pinnacle of research quality-are often used in guideline development; however, pain may differ across cultures and communities. Thus, examination of equity reporting in such SR is necessary. This study examines reporting using the PROGRESS (Place of resident, Race, Occupation, Gender, Religion, Education, Socioeconomic status, Social capital)-Plus framework to examine equity within SRs with patient reported outcomes of chronic, non-cancer pain. A systematic search for SRs was conducted, which were evaluated for PROGRESS-Plus items and study characteristics were extracted. Among the 46 included SRs, seven did not include any PROGRESS-Plus items. The most commonly reported items were , included within 34 SRs, followed by (30/46), and (14/46). All other items were reported in five or less studies. Our investigation revealed a deficiency in SR's reporting of equity measures for opioid treatment of chronic non-cancer pain. Given the need to address healthcare disparities among minorities, implementing the PROGRESS-Plus framework may influence QoL and patient-centered care.

Fear Learning in Genital Pain: Toward a Biopsychosocial, Ecologically Valid Research and Treatment Model.

Although fear learning mechanisms are implicated in the development, maintenance, exacerbation, and reduction of genital pain, systematic research on how fear of genital pain emerges, spreads, persists, and reemerges after treatment is lacking. This paper provides an overview of the literature on pain-related fear, integrates the ideas on learning and sexual arousal responding, and specifies the pathways through which compromised learning may contribute to the development and persistence of genital pain. In order to refine theories of genital pain and optimize treatments, we need to adopt a biopsychosocial framework to pain-related fear learning and uncover potential moderators that shape individual trajectories. This involves examining the role of physiological processes, subjective experiences, as well as partner and relational cues in fear acquisition, excessive generalization and impaired safety learning, extinction of fear, counterconditioning, and return of fear. Recent methodological advances in fear conditioning and sex research are promising to enable more symptom-specific and ecologically valid experimental paradigms.

The foundations for chronic low back pain management may start in early life. Exploring the role of caregiver postnatal leave on future low back pain in the offspring.

Chronic low back pain is difficult to treat and despite increased spending on health services, clinical outcomes for people with low back pain have not improved. Innovative, large scale initiatives seem necessary to stem the cost of low back pain. Psychological health contributes to the development and persistence of chronic low back pain and psychological interventions are important in the management of low back pain. Given the contribution of psychological health to low back pain development and management, it raises the question; can we support psychological health in later life by bolstering emotional development in early life, and reduce the burden of this common condition? Positive early life experiences, including those induced by extended paid postnatal leave, could bolster emotional development and support the psychological health necessary to manage low back pain in later life. We present the current state of evidence demonstrating the potential value of increasing support for parent-child relationships in early life to reduce the burden of low back pain in future generations. The current evidence is limited to cross-sectional associations, but strong preclinical data clearly shows the potential negative impacts of maternal separation on rodent pup health that compels consideration in human populations. PERSPECTIVE: The benefits stemming from enhanced child development include stable emotional foundations, possibly improving psychological health and low back pain management in the future. This perspective raises questions for future studies – within the context of low back pain, what ingredients bolster stable psychological health? And are these ingredients influenced by postnatal leave?

Activation of neuronal FLT3 promotes exaggerated sensorial and emotional pain-related behaviors facilitating the transition from acute to chronic pain.

Acute pain has been associated with persistent pain sensitization of nociceptive pathways increasing the risk of transition from acute to chronic pain. We demonstrated the critical role of the FLT3- tyrosine kinase receptor, expressed in sensory neurons, in pain chronification after peripheral nerve injury. However, it is unclear whether injury-induced pain sensitization can also promote long-term mood disorders. Here, we evaluated the emotional and sensorial components of pain after a single (SI) or double paw incision (DI) and the implication of FLT3. DI mice showed an anxiodepressive-like phenotype associated with extended mechanical pain hypersensitivity and spontaneous pain when compared to SI mice. Behavioral exaggeration was associated with peripheral and spinal changes including increased microglia activation after DI versus SI. Intrathecal microglial inhibitors not only eliminated the exaggerated pain hypersensitivity produced by DI but also prevented anxiodepressive-related behaviors. Behavioral and cellular changes produced by DI were blocked in Flt3 knock-out animals and recapitulated by repeated intrathecal FL injections in naive animals. Finally, humanized antibodies against FLT3 reduced DI-induced behavioral and microglia changes. Altogether our results show that the repetition of peripheral lesions facilitate not only exaggerated nociceptive behaviors but also induced anxiodepressive disorders supported by spinal central changes that can be blocked by targeting peripheral FLT3.
