Low back pain and kinesiophobia in pregnant women.

During pregnancy, many pregnant women experience lumbopelvic pain due to mechanical, systemic, and hormonal reasons and this pain and fear of movement (kinesiophobia) causes daily life limitations. To examine low back pain (LBP), kinesiophobia, disability, and related conditions that develop together during pregnancy. The was a cross-sectional and analytical study. The presence, severity, and duration of pain in the lumbopelvic region were questioned. Postpartum LBP was evaluated using a self-administered questionnaire, disability using the Oswestry Disability Index (ODI), pain intensity using a visual analog scale (VAS), physical activity levels using the physical activity level during pregnancy questionnaire and the international physical activity questionnaire short form, and kinesiophobia was evaluated using the Tampa Scale for Kinesiophobia. The study comprised 120 pregnant women with a mean age of 27.4 ± 6.1 years. It was observed that 42.3% of the pregnant had LBP (n= 69). The mean body mass index (BMI) was 73.6 ± 16.2 kg/m2, and the mean VAS score was 5.5 ± 2 cm. When we divided the group according to the presence of LBP, age (p= 0.49), gestational week (p= 0.75), and gravida (p= 0.81) were similar. BMI (p= 0.038) and ODI scores (p< 0.001) were higher in the group with LBP. LBP in pregnant women has a higher frequency than in the normal population, regardless of age, gestational week, and gravida. Obesity appears to be a risk factor for LBP and increases disability. Kinesiophobia in pregnant women is significantly associated with obesity and disability. Unless there are contraindications, a physically active pregnancy process and regular exercise should be recommend.

Diagnosa Penyakit Kelamin (Vulvodynia) pada Wanita Menggunakan Metode Certainty Factor

Vulvodynia is a chronic pain condition affecting the vulva that significantly impacts women’s quality of life. Accurate and early diagnosis poses a challenge due to the often-overlapping symptoms with other conditions and the lack of definitive diagnostic tests. This paper proposes the use of expert system methods as a diagnostic tool for vulvodynia in women. The expert system, integrating medical knowledge with inference algorithms, is designed to analyze symptoms, medical history, and test results to provide accurate diagnoses and treatment recommendations. The study involves the development and evaluation of a computer-based expert system prototype that uses clinical data and medical decision-making to enhance the accuracy of vulvodynia diagnosis. Preliminary results indicate that the expert system can improve diagnostic rates and reduce the time required for identifying this condition, offering a potentially valuable tool for medical professionals in clinical practice.

Symptoms of depression, anxiety and stress in women with chronic pelvic pain attended at a private hospital in São Luís, Maranhão: a cross-sectional study

ABSTRACT The study aimed to evaluate the relation between depression, anxiety stress symptoms, duration and pain intensity in women with chronic pelvic pain (CPP). This study consisted of a sample of women diagnosed with CPP from April 2021 to August 2023, including women aged 18 years or older who agreed in writing to participate in the study with the Free Informed Consent Form, who could understand the study’s objectives and participate. Women between 31 and 37 years old, married or in a stable relationship, with a higher education degree predominated. Were observed outside the normal range scale 58.8 percent of depression, 66.7 percent of anxiety and 59.8 percent of stress. The level of alteration most often observed in patients was extremely severe in 24 percent of with depression and 33.3 percent of anxiety, and the level was mild in 19.6 percent of stress symptoms. No statistical association was found between duration of pain and emotional states of anxiety, depression or stress. Regarding pain intensity levels, there was no significant association with the presence or absence of symptoms of depression outside the normal range or its levels. It’s was significantly associated with the presence or absence of anxiety symptoms outside the normal range (p = .003) and with their levels (p = .005). Also significantly associated with the presence or absence of stress symptoms outside the normal range (p = .007), as was its levels (p = .023). The symptoms of depression, anxiety and stress occur frequently in women with CPP and that the intensity of pain experienced is significantly associated with the presence of stress and anxiety but not with depression.

Somatic, emotional, and gastrointestinal symptom severity are increased among children and adolescents with COVID-19.

Post-infectious disorders of gut-brain interaction (PI-DGBI) have significant impact on children and adolescents. The effect of COVID-19 on PI-DGBI-associated symptoms in this population, however, is unknown. We performed electronic medical record searches to identify patients 8-17 years old with a SARS-CoV2 PCR test at Lurie Children's Hospital between November 2020 and March 2021 (cohort 1) and April-October 2021 (cohort 2). Questionnaires were administered to assess symptoms prior to and 3 months following the test. This included the Pediatric Eosinophilic Esophagitis Symptom Score (PEESS), questionnaire of pediatric gastrointestinal symptoms-Rome IV, Nausea Profile (NP), dyspepsia symptom survey (DSS), nausea severity profile (NSP), and Pediatric Quality of Life Inventory (PedsQL). We grouped patients based on the presence of symptoms prior to COVID-19 test or the test result. One hundred and ninety-six parent(s) or guardian(s) in cohort 1 and 274 in cohort 2 completed surveys and self-reported their child's COVID-19 result. Cohort 1 had increased PEESS and DSS scores, lower PedsQL scores, and increased frequency of abdominal pain disorders among patients with symptoms prior to COVID-19 testing. Both cohorts had increased NP and NSP scores among patients with symptoms prior to COVID-19 testing that was highest among patients with a positive COVID-19 test. Abdominal pain and diarrhea prior to COVID-19 testing predicted higher NP scores. Among symptomatic COVID-19 tested children, we found increased severity of nausea-associated somatic, emotional, and gastrointestinal symptoms in the 3 months following the test that was most increased among patients with a positive COVID-19 test.

Nationally Representative Rates of Incident Prescription Opioid Use Among United States Adults and Selected Subpopulations: Longitudinal Cohort Study from the National Health Interview Survey, 2019-2020

Nationally representative rates of incident prescription opioid use in the United States (U.S.) adult population and selected subpopulations are unknown. Using the National Health Interview Survey (2019-2020) longitudinal cohort, a cohort with 1-year follow-up created using random cluster probability sampling of non-institutionalized civilian U.S. adults, we estimated rates and predictors of incident opioid use. Of 21,161 baseline (2019) participants randomly chosen for follow-up, the final analytic sample included 10,415 who also participated in 2020. Exposure variables were selected per the socio-behavioral model of healthcare utilization: predisposing characteristics (sex, age, race, etc.), enabling characteristics (socioeconomic status, insurance status), health status (pain, disability, comorbidities, etc.), and healthcare use (office visits, emergency room [ER] visits, hospitalizations). Among adults who did not use prescription opioids in 2019, a one-year cumulative incidence of 4.1% (95% CI:3.5-4.6) was seen in 2020, with an incidence rate (IR) of 32.6 cases of new prescription opioid use per 1,000 person-years (PY). Cumulative incidence, IR, and adjusted relative risk (RR) varied by participant characteristics. We observed the highest IR in those with ineffective pain treatment (81.6 cases per 1,000 PY) and those who visited the ER ≥3 times (93.8 cases per 1,000 PY). Participants reporting ≥4 painful conditions had an adjusted RR of 2.9 (95% CI:2.0-4.1), while the RR for those with sleep problems was 2.3 (95% CI:1.7-3.1). Overall, this study presents nationally representative rates of incident prescription opioid use, and suggests that some participants are using prescription opioids as an early resort analgesic contrary to best practice guidelines. PerspectiveThis longitudinal cohort study presents nationally representative rates of incident prescription opioid use in U.S. adults and selected subpopulations. Our data suggest that some participants are using prescription opioids as a first-line or early resort analgesic, contrary to best practice guidelines.

Tramadol effects on brain activity during cognitive and emotional empathy for pain: a randomized controlled study

Pain is perceived not only by personal experience, but also vicariously. Pain empathy is the ability to share and understand other’s intentions and emotions in their painful conditions, which can be divided into cognitive and emotional empathy. It remains unclear how centrally acting analgesics would modulate brain activity related to pain empathy, and which component of pain empathy would be altered by analgesics. In this study, we examined the effects of the analgesic tramadol on the brain activity for pain empathy in healthy adults. We used two tasks to assess brain activity for pain empathy. In experiment 1, we used a well-established picture-based pain empathy task involving passive observation of other’s pain. In experiment 2, we developed a novel pain empathy task to assess brain activity during cognitive and emotional empathy for pain separately in a single task. We conducted a double-blind, placebo-controlled within-subject cross-over study with functional magnetic resonance imaging for 33 participants in experiment 1 and 31 participants in experiment 2, respectively. In experiment 1, we found that tramadol decreased activation in the supramarginal gyrus (SMG) during observation of other's pain compared to placebo. SMG activation correlated negatively with the thermal pain threshold. In experiment 2, we found that tramadol decreased activation in angular gyrus in cognitive empathy for pain compared to placebo, but didn’t change brain activity in emotional empathy for pain. PerspectiveCentrally acting analgesics such as tramadol may have not only analgesic effects on self-experienced pain, but also on the complex neural processing of pain empathy.

The effect of trunk position and pain location on lumbar extensor muscle recruitment strategies.

The aim of this study was to investigate the effect of trunk position and experimental lumbar pain location on lumbar extensor muscle recruitment strategies. Nineteen healthy participants (10 men and 9 women), aged 25.3 ± 4.7 yr, performed isometric back extension contractions in three positions (neutral, 45°, and 90° trunk flexion) and under three conditions (no pain, caudal pain, and cranial pain). Lumbar muscle activation strategies were recorded using high-density surface electromyography. The effect of position and pain condition on muscle activity amplitude and spatial redistributions was assessed. Muscle activity amplitude was 43% higher in 45° trunk flexion than in neutral position on both sides (P < 0.05). In the 90° trunk flexion, participants showed a more lateral spatial distribution than in the 45° trunk flexion on the left side (P < 0.01, 5.4 mm difference) and the neutral position on both sides (P < 0.05, 8.2 mm difference). In the 45° trunk flexion, participants exhibited a more lateral spatial distribution compared with the neutral position on the right side (P < 0.05, 3.7 mm difference). A lateral spatial redistribution of muscle activity was observed in the caudal pain condition compared with the no pain condition on the right side (P < 0.05, 3.0 mm difference). Individual responses to pain varied across all variables. Different trunk positions result in different distributions of activation within the lumbar extensor muscles, possibly based on regional mechanical advantage. No clear indication of location-specific pain adaptation and no effect of task-dependent pain adaptation were found, whereas individual-specific adaptations were observed.NEW & NOTEWORTHY Changes in muscle activity amplitude and spatial redistribution of lumbar extensor muscles were observed in different trunk positions, potentially due to changes in their mechanical advantage. The results complement the current pain-adaptation theory by illustrating individual spatial redistributions of activation within lumbar extensor muscles during pain. The study found no clear indication of location-specific pain adaptation and no effect of task-dependent pain adaptation.

Development of Postsurgical Pyoderma Gangrenosum with New Keloid after Keloid Resection.

Keloids are a dermal fibroproliferative disorder and can arise from trauma, acne, vaccination, and herpes zoster. Pyoderma gangrenosum (PG) is a painful ulcerative skin disorder that is associated with neutrophilic dysfunction. However, the pathophysiologies of keloids and PG are not fully understood. The authors encountered an unusual case of a 24-year-old woman who presented with an anterior chest keloid that bore an ulcer. The keloid was resected along with the ulcer, and histology revealed the ulcer to be a neutrophilic PG ulcer. A year after surgery, another ulcer developed in the scar. The ulcer met the PARACELSUS criteria of a postsurgical PG ulcer. After treatment with systemic prednisone and adalimumab for 250 days, the ulcer re-epithelialized. However, relapsed keloids were then observed at the PG site. Corticosteroid taping may be the safest therapy for patients with a history of PG. Conversely, if there is suspicion that a patient is prone to keloid development, diagnostic biopsies and surgical management of PG ulcers should be avoided or conducted with care.

Interdisciplinary Pain Board for Managing Patients with Palliative Care Needs and Substance Use Disorder: A Pilot Study.

Context: Patients with cancer-related pain and concurrent substance use disorder (SUD) present a unique set of challenges for palliative care clinicians. A structured forum for interdisciplinary collaboration is needed to effectively manage this complex population. Objectives: Describe the feasibility and acceptability of a palliative care Complex Pain Board (CPB), an interdisciplinary team meeting to provide concrete care recommendations for patients with cancer-related pain and concurrent SUD and/or psychosocial complexity. Methods: We conducted a retrospective analysis of cases presented at CPB between May 2021 and June 2022 and a cross-sectional analysis of CBP participant surveys. Results: Among 28 cases included for analysis, gastrointestinal cancers (n = 7, 25.9%) and multiple myeloma (n = 5, 18.5%) were the most frequent cancer diagnoses. Primary reasons for referral were SUD (n = 22, 78.6%) and provider/team distress (n = 13, 46.4%). The most frequent recommendations made at CBP were encouraging interdisciplinary collaboration (n = 18, 64.3%), maintaining healthy boundaries (n = 15, 53.6%), and SUD management (n = 13, 46.4%). Of 14 scheduled meetings, most meetings involved the presentation of ≥1 cases (n = 12, 86%). Among 40 CBP participant surveys, most attendees (n = 38, 95%) were likely or highly likely to continue to attend. Conclusion: CPB is a feasible and acceptable intervention that allows for palliative care clinicians to collaborate and receive interdisciplinary team feedback and peer support on the management of patients with cancer-related pain and concurrent SUD and/or psychosocial complexity in the ambulatory care setting. Key Message: A regular, interdisciplinary team meeting (CPB) is a feasible and acceptable intervention to help palliative care clinicians manage challenging cases involving patients with cancer and concurrent SUD and/or psychosocial complexity.

Trends in Utilization and Cost of Nonpharmacological Pain Therapies in the United States Under Medicare Part B, 2000-2022.

Background: Many clinical practice guidelines for management of pain disorders now favor first-line use of nonpharmacological therapies (NPT). However, Medicare coverage of NPT is limited. Methods: Using a serial cross-sectional design, we examined temporal trends in the utilization and cost of NPT procedures commonly used to treat pain under Medicare. Results: Utilization and costs for physical therapy increased while those for spinal and osteopathic manipulation declined. Discussion: Future research on NPT under Medicare should focus on equity of patient access and comparative outcomes.

Diet and Lifestyle Modifications for Fibromyalgia.

Fibromyalgia (FM) is a complex, widespread pain disorder characterized by symptoms such as fatigue, sleep deprivation, mental fog, mood swings, and headaches. Currently, there are only three FDA-approved medications for FM patients: duloxetine, milnacipran, and pregabalin, with outcomes frequently being inadequate. This research team aims to investigate the effects of diet and lifestyle modifications on FM, with emphasis on anti-inflammatory diet, antioxidants, and gluten-free diets, as well as supplementation with Magnesium, CQ10, and Vitamin D, microbiome, sleep, exercise, and cognitive behavioral therapy. We reviewed the pathophysiology of certain foods that can be proinflammatory with the release of cytokines leading to activation of pain, fatigue and aggravation of the majority of Fibromyalgia symptoms. A literature review was performed by identifying FM articles published between 1994 and 2022 via PubMed and EMBASE databases, with particular emphasis on randomized controlled trials, meta-analysis, and evidence-based treatment guidelines. This review article was completed by a comprehensive narrative review process, in which our team systematically examined relevant scientific literature to provide a comprehensive overview of the significant role that diet and other lifestyle modifications play in mediating symptoms of Fibromyalgia. We propose that diet modifications and lifestyle changes, such as sleep, exercise, and weight loss, can be important steps in managing FM.

Do Maladaptive Imaging Beliefs Predict Self-Reported Pain Interference and Physical Function in Patients With Musculoskeletal Disorders?

OBJECTIVE: To determine if maladaptive imaging beliefs correlated with, and predicted pain interference and physical function outcomes in people with musculoskeletal pain disorders. DESIGN: A prospective cohort study of patients with musculoskeletal disorders receiving outpatient physical therapy from April 2022 to August 2023. METHODS: Four questions about imaging were asked to assess maladaptive beliefs, the need to rule out serious conditions, guide treatment, determine diagnosis, and validate symptoms. Correlations with beliefs and outcomes were assessed using Kendall's tau rank and Spearman's rho correlation coefficients. Generalized linear models determined if these beliefs predicted outcomes at baseline and 6 weeks. RESULTS: The cohort included 152 participants (mean [standard deviation] age: 56.13 [15.13]; 32.2% male). Maladaptive imaging beliefs correlated positively with pain interference and negatively with physical function. The need to rule out serious conditions and validate symptoms correlated with pain interference (range: τb = 0.17, 0.20; P = .003, .0121) and physical function (range: ρ = -0.22, -0.22; P = .006, .008). All but 1 belief correlated with pain interference (range: τb = 0.19, 0.24; P<.001, .004) and physical function (range: ρ = -0.26, -0.21; P = .001, .009) at 6 weeks. Each additional belief slightly increased pain interference at 6 weeks (β = 0.01; 95% CI: 0.001, 0.03; P = .04) and lowered physical function at both baseline (β = -0.97; 95% CI: -1.66, -0.28; P = .01) and 6 weeks (β = -0.76; 95% CI: -1.37, -0.15; P = .02). CONCLUSION: Maladaptive imaging beliefs were significantly (albeit weakly) correlated with pain and physical function. Each additional maladaptive imaging belief increased pain interference at 6 weeks and lowered physical function at baseline and 6 weeks. Beliefs about the necessity of imaging to properly manage musculoskeletal disorders may influence outcomes. J Orthop Sports Phys Ther 2024;54(9):1-10. Epub 5 July 2024. doi:10.2519/jospt.2024.12625.

Cells and circuits for amygdala neuroplasticity in the transition to chronic pain

Maladaptive plasticity is linked to the chronification of diseases such as pain, but the transition from acute to chronic pain is not well understood mechanistically. Neuroplasticity in the central nucleus of the amygdala (CeA) has emerged as a mechanism for sensory and emotional-affective aspects of injury-induced pain, although evidence comes from studies conducted almost exclusively in acute pain conditions and agnostic to cell type specificity. Here, we report time-dependent changes in genetically distinct and projection-specific CeA neurons in neuropathic pain. Hyperexcitability of CRF projection neurons and synaptic plasticity of parabrachial (PB) input at the acute stage shifted to hyperexcitability without synaptic plasticity in non-CRF neurons at the chronic phase. Accordingly, chemogenetic inhibition of the PB→CeA pathway mitigated pain-related behaviors in acute, but not chronic, neuropathic pain. Cell-type-specific temporal changes in neuroplasticity provide neurobiological evidence for the clinical observation that chronic pain is not simply the prolonged persistence of acute pain.

Knowledge and Experience of In-Home Virtual Reality for Chronic Pain in Sickle Cell Disease

Many adults with sickle cell disease experience chronic, nonvaso-occlusive pain that can benefit from nonpharmacological interventions available for use in the home setting. Virtual reality (VR) has been shown to be effective in decreasing pain in chronic pain conditions and may be useful for home-based self-management of chronic pain in sickle cell. However, the literature lacks studies examining this potential. Additionally, the knowledge and experiences of adults with sickle cell who have tried VR for home-based chronic pain management have not yet been reported. This qualitative, descriptive pilot study explored the knowledge and perceptions of VR among adults with sickle cell and their experience with using in-home VR for chronic pain. Nine participants completed demographic questionnaires and an individual interview that was recorded, transcribed verbatim, and analyzed using thematic analysis. Participants were 21 to 38 years of age, and most were female (88.9%) with a medium or high sickle cell disease severity (88.9%) and a chronic pain-grade classification of grade III (high disability-moderately limiting) or grade IV (high disability-severely limiting) (55.5%). Interview themes, which aligned with the technology acceptance model, were 1) pain beliefs and self-management, 2) VR as another world, and 3) experience of using in-home VR. Based on preliminary data, VR shows promise as a strategy for nonpharmacological management of chronic pain in adults with sickle cell. However, further investigations are warranted to mitigate the challenges and limitations associated with using VR in this capacity. PerspectiveFew evidence-based, nonpharmacological interventions exist for chronic pain in adults with sickle cell disease. This first qualitative, pilot study of in-home VR for chronic pain in adults with sickle cell disease suggests that VR interventions need further exploration as a nonpharmacological strategy for mitigating their pain in the home setting.

Randomised controlled pilot trial of the EndoSMS supportive text message intervention for individuals with endometriosis: Feasibility and acceptability results

ObjectiveDiminished quality of life, inadequate support and social isolation are commonly experienced by individuals living with the chronic pain condition, endometriosis. We aimed to determine the feasibility and acceptability of EndoSMS, a psychologically-focused text message intervention designed to support individuals living with endometriosis. MethodsAs part of a two-arm parallel pilot randomised controlled trial with waitlist control, the feasibility and acceptability of a brief (3-month) version of EndoSMS was assessed using a mixed methods approach. Feasibility data (uptake, attrition, text message delivery analytics) and user acceptability (via self-report survey items and written feedback) were assessed. Qualitative data were thematically analysed using the template approach. Primary trial outcomes are not reported in this paper. ResultsFeasibility was indicated by: high conversion rate (99.1 %), low attrition (14.2 %), few opt-outs (0.02 %) and a high message delivery rate (99.8 %). Most intervention participants indicated user acceptability (mean = 4.02/5) across self-report questions. Most rated the length of the program (65.5 %), and the number (80.9 %) and language (94.5 %) of the text messages to be ‘just right’. Thematic analysis created four themes: A shared “battle”: Feeling less isolated and alone; “Be kind to yourself”: A focus on self-care, self-compassion and active coping; Keeping endometriosis at the forefront: Helpful or stressful?; Mixed perceptions surrounding the provision of general endometriosis information; and, Tailoring of text messages. ConclusionEndoSMS supportive text message program was feasible and acceptable for individuals with endometriosis. Future developments of the program should consider greater tailoring of content to user needs.Trial Registration: Australian New Zealand Clinical Trials Registry (ACTRN12621001642875).

Association of cannabis use with patient-reported pain measures among adults with chronic pain in US states with medical cannabis programs

Threatening an Illusory Limb: An Event-related Potential Study of the Rubber Hand Illusion.

The rubber hand illusion (RHI) is a well-established method for studying body ownership: Given adequate concordance of visual, sensory, and proprioceptive stimuli, the individual experiences a rubber hand as his or her own. To study the effects of a threat to the rubber hand. We created a typical RHI paradigm but added threatening pain: Both the real hand of an individual and the rubber hand were stroked with a brush, either synchronously (RHI-inducing condition) or asynchronously (control condition), but only the rubber hand was then pricked with a needle to create a threatening pain condition. Event-related potentials (ERPs) were recorded in a group of 23 typically-developed individuals. ERP effects were source-localized using low-resolution electromagnetic tomography. The individuals consistently reported experience of the RHI during the experiment when the brush strokes were applied synchronously to both the real hand and the rubber hand. ERP analysis revealed that synchronous brush stroking gave rise to higher amplitude of frontal ERPs in the 100-200 ms range than asynchronous brush stroking, which was interpreted as reflecting the RHI. In the threatening pain condition, ERPs showed a greater positivity at frontocentral electrodes, source localized in the supplementary motor area (SMA). SMA activation could reflect a control mechanism over reflexive motor activity, facilitating a possible threat-related response. Further studies should address ERP effects and the extent of the RHI to standard and threat stimuli in a correlative fashion to further elucidate the functional significance of the neurophysiological findings.

Randomized, placebo-controlled study on the effects of intravenous GSK3858279 (anti-CCL17) on a battery of evoked pain tests in healthy participants.

C-C Motif Chemokine Ligand 17 (CCL17) is a chemokine that binds and signals through the G-protein coupled CC-chemokine receptor 4 and has been implicated in the development of inflammatory and arthritic pain. GSK3858279 is a high-affinity, first-in-class, monoclonal antibody, binding specifically to CCL17 and inhibiting downstream signaling. In this phase I, randomized, single-center, double-blind, placebo-controlled, three-period, incomplete-block crossover study (NCT04114656), the analgesic effects and safety of intravenous GSK3858279 were assessed in a battery of evoked acute pain assessments on healthy, adult (aged ≥18 years), male participants. Participants were randomized 1:1 to receive either one placebo (0.9% w/v NaCl) dose followed by two GSK3858279 doses (PAA treatment sequence), or one GSK3858279 dose followed by two placebo doses (APP treatment sequence). The co-primary end points were ultraviolet B heat pain detection threshold (°C), cold pressor time to pain tolerance threshold (PTT, sec), and electrical PTT (mA, single stimulus). Twenty-one participants were enrolled (PAA = 11; APP = 10). Mean age (standard deviation) was 29.3 (7.9) years for PAA, 31.1 (7.7) years for APP. No significant differences were observed in the analgesic effect between GSK3858279 and placebo for any end point. Exposure to GSK3858279 was similar between Period 1 (APP sequence), and Periods 2 and 3 (PAA sequence), with some GSK3858279 carry-over. Changes in serum CCL17 levels were consistent with the expected GSK3858279 activity. All drug-related adverse events were mild in intensity and caused no discontinuations. The absence of an efficacy signal in this acute pain model does not preclude efficacy in chronic pain states.

The Physical Sensation of Precordial Pain as a Signal of Psychiatric Relevance of Anguish

Anguish is a sensation of precordial chest tightness or oppression that has an emotional origin. Unlike anxiety which is focused on the future, anguish is experienced in the present as a state of pain and mental agony. Furthermore, distress is supposed to have different autonomic, physiological and biochemical reactions when compared to anxiety and depression. The main objective of this work is to investigate whether depression is more related to anguish than anxiety, and also to identify which variables or symptoms are most predictive of the state of anguish. A binomial logistic regression model was adjusted and statistically significant evidence was found that depression may be more related to distress than anxiety. An important depression diagnostic variable (MINI Depression) was selected in the model (at the 10% level) and its interpretation corroborates the central hypothesis of the study mentioned above. Correspondence analysis also points to clues in the direction of the research hypothesis. As for the second objective, under the same logistic model, the following variables were shown to be related to the state of distress: Gender, Reduced Hamilton Score, BSI Somatization, BSI Hostility, BSI Obsession Compulsion, Age and MINI Depression.

A pragmatic approach to teaching physician assistant students basic pain management.

Chronic pain is increasing in prevalence, with new cases now outnumbering those of diabetes, depression, or hypertension. Advanced practice providers have reported that their training in pain management inadequately prepared them to care for patients suffering from painful conditions. In response, the authors of this work developed a basic pain management conceptual framework to provide physician assistant (PA) students with the foundational knowledge necessary to manage and treat patients suffering from a wide variety of painful conditions. The devised framework activity includes categories of pain management such as conservative therapies, medications, injections, minimally invasive procedures, and moderately to highly invasive procedures. This framework can be incorporated into the existing PA educational curriculum and presented alongside a realistic pain patient case study. Furthermore, other health science educational programs, such as nurse practitioner or pharmacy programs, could adopt this framework to increase student knowledge in pain management.
