Non-specific chronic low back pain (NCLBP) has a high incidence, which has a significant impact on a patient's body and mind and is a common condition affecting people's quality of life. Core stability exercise (CSE) is a modestly effective treatment for NCLBP; however, CSE has only been shown to be a useful treatment option in the short term. Many clinical practice guidelines recommend the use of a biopsychosocial framework to guide the management of NCLBP. Self-compassion training (SCT) is a promising psychotherapy treatment option for NCLBP; however, there is still a lack of research on CSE combined with SCT. In this study, we will seek to determine whether CSE combined with SCT is an effective treatment option for patients with NCLBP compared to CSE alone.

The impacts of COVID-19 and imposed restrictions on individuals with chronic noncancer pain continue to emerge, varying across countries. More recent research (including with longitudinal designs) suggests that the pandemic may not have such a disproportionate effect on chronic noncancer pain and its management as first thought. This longitudinal study, with assessments before the pandemic (2019) and early during the pandemic (May-July 2020), examined changes in validated measures of pain severity, pain interference, prescription opioid misuse, and mental health symptoms. Patients (N = 236) self-reported significant improvements in pain severity, pain interference, pain self-efficacy, pain catastrophizing, prescription opioid misuse, depression, and anxiety symptoms over time. Approximately 30% and 33% of patients achieved minimally important reductions (10% change) in pain severity and pain interference, respectively. In follow-up exploratory analyses, prepandemic sociodemographic and psychological factors predictive of 10% improved (vs 10% worse) pain severity and interference were investigated in logistic regressions. Reduction in pain interference was predicted by current employment, older age, and higher pain self-efficacy. There were no significant predictors of reduction in pain severity. The impact of COVID-19 on patients' pain experience and mental health was negligible in the early stages of the pandemic, and findings suggest improvements through the period. Targeted interventions that promote the protective factor of pain self-efficacy and build resilience may buffer patients' future response to the pandemic because it evolves as a part of our new normal. Targeted social determinants of health interventions that direct resources toward maintaining employment could also be important.

Acute hepatic porphyrias (AHPs) are a family of four rare genetic diseases resulting from a deficiency in one of the enzymes involved in heme biosynthesis. AHP patients can experience potentially life-threatening acute attacks, characterized by severe abdominal pain, along with other signs and symptoms including nausea, mental confusion, hyponatraemia, hypertension, tachycardia and muscle weakness. Some patients also experience chronic manifestations and long-term complications, such as chronic pain syndrome, neuropathy and porphyria-associated kidney disease. Most symptomatic patients have only a few attacks in their lifetime; nevertheless, some experience frequent attacks that result in ongoing symptoms and a significant negative impact on their quality of life (QoL). Initial diagnosis of AHP can be made with a test for urinary porphobilinogen, [Formula: see text]-aminolaevulinic acid and porphyrins using a single random (spot) sample. However, diagnosis is frequently missed or delayed, often for years, because the clinical symptoms of AHP are non-specific and mimic other more common disorders. Delayed diagnosis is of concern as some commonly used medications can trigger or exacerbate acute attacks, and untreated attacks can become severe, potentially leading to permanent neurological damage or fatality. Other attack triggers include hormonal fluctuations in women, stress, alcohol and low-calorie diets, which should be avoided in patients where possible. For the management of attacks, intravenous hemin is approved, whereas new therapeutic approaches are currently being investigated as a baseline therapy for prevention of attacks and improvement of QoL. Among these, a novel siRNA-based agent, givosiran, has shown very promising results in a recently concluded Phase III trial and has been approved for the management of AHPs. Here, we propose a challenging case study-with a very unusual pediatric onset of variegate porphyria-as a starting point to summarize the main clinical aspects (namely, clinical manifestations, diagnostic challenges, and therapeutic management) of AHPs, with a focus on the latest therapeutic innovations.

The neuroinflammatory response to surgery can be characterized by peripheral acute plasma protein changes in blood, but corresponding, persisting alterations in cerebrospinal fluid (CSF) proteins remain mostly unknown. Using the SOMAscan assay, we define acute and longer-term proteome changes associated with surgery in plasma and CSF. We hypothesized that biological pathways identified by these proteins would be in the categories of neuroinflammation and neuronal function and define neuroinflammatory proteome changes associated with surgery in older patients.

This systematic review and meta-analysis aimed at evaluating the role of sleep disturbances and sleep disorders in influencing presence and intensity of chronic postsurgical pain (CPSP). We included cohort studies which enrolled adults, assessed sleep disturbances or disorders before surgery, measured pain intensity, presence of pain, or opioid use at least three months after surgery. Eighteen studies were included in a narrative synthesis and 12 in a meta-analysis. Sleep disturbances and disorders were significantly related to CPSP, with a small effect size, r = 0.13 (95% CI 0.06-0.20). The certainty of evidence was rated low due to risk of bias and heterogeneity. In subgroup analyses the above association was significant in studies that used pain intensity as the outcome, but not in those that used presence of pain; in studies on patients who underwent total knee arthroplasty or other surgeries, but not in those on patients who had breast cancer surgery or total hip arthroplasty; in the single study that assessed insomnia and in studies that assessed sleep disturbances as predictors. A meta-regression showed that the follow-up length was positively associated with the overall estimate. Our findings suggest that presurgical sleep disturbances and disorders should be evaluated to detect patients at risk for CPSP.

Practice-based guidelines recommend patient education and exercise as first-line care for low back pain (LBP); however, these recommendations are not routinely delivered in practice. GLA:D® Back, developed in Denmark to assist clinicians to implement guideline recommendations, offers a structured education and supervised exercise program for people with LBP in addition to a clinical registry to evaluate patient outcomes. In this study we evaluated the feasibility of implementing the GLA:D® Back program in Australia. We considered clinician and patient recruitment and retention, program fidelity, exploring clinicians' and patients' experiences with the program, and participant outcome data collection.

Both heart failure (HF) and insomnia are associated with high symptom burden that may be manifested in clustered symptoms. To date, studies of insomnia have focused only on its association with single symptoms. The purposes of this study were to: (1) describe daytime symptom cluster profiles in adults with insomnia and chronic HF; and (2) determine the associations between demographic and clinical characteristics, insomnia and sleep characteristics and membership in symptom cluster profiles.

The bicyclic nucleoside analogue (BCNA) Cf1743 and its orally bioavailable prodrug FV-100 have unique potential as varicella-zoster virus (VZV) inhibitors to treat herpes zoster (shingles) and the therewith associated pain, including post-herpetic neuralgia (PHN). The anti-VZV activity of Cf1743 depends on a specific phosphorylation by the VZV-encoded thymidine kinase (TK). The target of antiviral action is assumed to be the viral DNA polymerase (or DNA synthesis in the virus-infected cells).

Cecal volvulus can be a rare and challenging diagnosis. We report a 47-year-old female who presented to the hospital and was diagnosed with acute appendicitis based on workup and clinical exam. The patient underwent laparoscopic appendectomy where the appendix was localized after extensive ascending colon mobilization. The patient's post-operative course was complicated by cecal volvulus requiring a right hemicolectomy. There have been several other reported cases of cecal volvulus following laparoscopic appendectomy, both of which also involved considerable cecal mobilization. More data are necessary to determine whether this clinical course could have been prevented with more limited mobilization or with cecopexy at initial surgery. A mobilized cecum may benefit from early surgical intervention to prevent future volvulus or a chronic mobile cecum syndrome. Cecal volvulus should be considered in the case of worsening abdominal pain or obstruction following laparoscopic appendectomy, given the consequences that can result if symptoms are overlooked.
