Psoriatic arthritis (PsA) is an inflammatory musculoskeletal disease related to several comorbidities. Anxiety is an important comorbidity in PsA and the data is scarce. We aimed to understand the rates before biologic agents and change in anxiety with the treatment.

The objective of this study was to compare the effect of adding meperidine or sufentanil to hyperbaric bupivacaine in patients undergoing elective cesarean delivery (CD) under spinal anesthesia. The primary outcome was the first analgesic request time, and secondary outcomes included an analgesic requirement in the first 24 h and intraoperative and postoperative side effects.

Rheumatoid arthritis (RA) is an inflammatory autoimmune disease involving symmetric joints and is generally characterized by persistent pain, tenderness, and destruction of joints. The vast majority of RA patients produce autoantibodies, and immune cell involvement in disease development is well recognized, as is the contribution of other types of cells in synovial tissue, like fibroblasts. It is known that there are major genetic associations with the HLA locus, while multiple non-HLA genetic variants display relatively low risk of RA. Both HLA and non-HLA associations suggest that the profiles of genetic associations for autoantibody-positive vs. autoantibody-negative RA are different. Several alleles of HLA-DRB1 are associated with high risk for autoantibody-positive RA, with the strongest risk characterized by valine at position 11 of the protein sequence (HLA-DRB1*04 and *10 alleles). There is a strong protective effect for the risk of autoantibody-positive RA associated with HLA-DRB1*13 alleles. Although major genetic associations have been known for several years, understanding of the specific mechanisms in the development of increased risk of RA for these variations is work in progress. Current studies focus on the binding of immune receptors involved in recognition of putative peptides in activation of T cells, as well as investigation of cell signaling mechanisms. At least a part of RA risk could be explained by gene-gene and gene-environment interactions. There are currently more than 150 candidate loci with polymorphisms that associate with RA, mainly related to seropositive disease, and new discoveries are anticipated in the future from investigation of diverse human populations. This new research will help create a strong foundation for the continuing process of integrating genetic, epigenetic, transcriptomic, and proteomic data in studies of RA.

Evidence on risk factors for postpartum depression (PPD) are fragmented and inconsistent.

This study aimed to determine the long-term level of pain after surgical treatment of one or more symptomatic rib fracture nonunions. Secondary aims were to evaluate the occurrence of adverse events, satisfaction, and activity resumption. The final aim was to assess the association between pain and the presence of bridging callus at the nonunified fracture. Hypothesized was that thoracic pain would diminish after surgery.

Standard cannulation practice for hemodialysis consists of inserting needles "blindly" through skin into an arteriovenous fistula (AVF), which is more likely to cause damage. Point-of-care ultrasound (POCUS) guided cannulation has potential for less damage; however, efficacy of this technique has not been explored. Our purpose was to test the feasibility and effectiveness of POCUS guidance for cannulation of AVFs in hemodialysis patients.

Irritable bowel syndrome (IBS) is a disorder of gut-brain interaction characterized by abdominal pain, bowel habits alterations, constipation, and/or diarrhea. Adverse childhood experiences (ACEs) are events such as abuse and mental illness causing childhood trauma. Studies report higher prevalence of ACEs in patients with IBS with varied effect consistency and association strength. A systematic review and meta-analysis were conducted to evaluate current literature, assess heterogeneity and research gaps in this relationship. A search across PubMed, Embase, PsycINFO, and Google Scholar with keywords ('childhood adversity' OR 'childhood trauma' OR 'adverse childhood events') AND ('irritable colon' OR 'irritable bowel syndrome') yielded 106 studies. A restricted maximum likelihood model of 15 chosen studies with 272,686 participants found the association between ACEs and IBS to be uncertain given the considerable heterogeneity (I=93.58%, p<0.001). Objective reporting methods for ACE and IBS, study size, and study quality explained some heterogeneity. Twelve studies showed publication bias (Egger's test, p<0.001), which further weakened interpretation. Gender-stratified subanalysis of three studies found ACEs associated with IBS in females (pOR=2.20, 95% CI (1.13 to 4.29), I=66.90%) with substantial heterogeneity, but no association in males (pOR=1.30, 95% CI (0.62 to 2.78)). This meta-analysis explores the current literature to understand the biopsychosocial perspective of IBS and ACEs' role as risk factors. However, the risk of publication and design/study quality biases substantiates the need for further research. If an association is confirmed, further mechanistic research and development of targeted psychological therapies may be warranted.

Nonmedical use of prescription opioids continues to be a public health crisis in the United States that disproportionately affects rural communities with diversion of pills from friends and family being the most common source. The primary goal of the study was to identify current opioid prescription practices, and to assess the discrepancy in amount of opioids prescribed by surgeons versus the amount needed post-operatively by patients. Patient factors that may influence postoperative analgesia needs and their management of leftover prescription opioids were also evaluated Patients ≥18 years-of-age who underwent a surgery between July and December 2018 by the subspecialty departments of Acute Care and General Surgery at a tertiary care facility in the rural Midwest were surveyed at their first post-operative visit to assess their postoperative analgesic needs. Resident and attending surgeons in the above departments were also surveyed to identify different factors that influenced their narcotic prescription practices. Surveys from 252 patients, 12 attending surgeons, and 14 general surgery residents met inclusion criteria. Of patients who received a narcotic prescription, 19.9% did not fill their prescription, 64.1% of whom were >60 years old, and 72.1% resided within an hour of the hospital. Average reported prescription size was 11-40 pills; however, most used more than 5 pills regardless of the type of operation (p=0.59) and history of chronic pain (p= 0.07). Inability to call in narcotic prescriptions and patients' distance from care influenced providers' prescription practices, with 77.9% of resident physicians and 68.3% of attending surgeons stating they would prescribe fewer if given the ability to call in a narcotic prescription. Regardless of the operation complexity, a majority of patients required fewer than five opioid pills after discharge and would be willing to return leftover pills. Development of opioid stewardship programs within the healthcare sector may reduce the number of opioids available for diversion and misuse.

Dl-3-n-butylphthalide (DL-NBP) has good neuroprotective function and is safe for use in patients with acute ischaemic stroke. DL-NBP induced anaphylactic shock is rarely reported. Here we describe the case of a 75-year-old woman who received an injection of DL-NBP (25 mg/100 mL intravenously guttae, twice daily) for acute ischaemic stroke. Approximately 5 min after the DL-NBP injection was administered, the patient developed a decrease in blood pressure and an increase in heart rate along with skin pruritus, mottlement of the lower limbs, discomfort, and the desire to defecate, following which DL-NBP was discontinued immediately. The patient recovered with antiallergic therapy and could tolerate further treatment. We emphasise that the increased use of DL-NBP in recent year raises the importance of attention to potential allergies in clinical use, especially in patients with a history of allergies to multiple drugs.

Patient-controlled analgesia (PCA) is an effective method for controlling acute pain, including postoperative pain in adults and in children from five years of age, pain resulting from labor, trauma, or other medical situations, or chronic and malignant pain. The treatment consists of a mini-computer-controlled infusion pump permitting the administration of on-demand, continuous, or combined doses of analgesic (mainly opioid) variations in response to therapy, which allows pain to be significantly controlled. Intravenous (IV)-PCA minimizes individual pharmacodynamics and pharmacokinetic differences and is widely accepted as a reference method for mild or severe postoperative pain. IV-PCA is the most studied route of PCA; other delivery methods have been extensively reported in the literature. In addition, IV-PCA usually voids the gap between pain sensation and analgesic administration, permitting better recovery and fewer side effects. The most commonly observed complications are nausea and vomiting, pruritus, respiratory depression, sedation, confusion and urinary retention. However, human factors such as pharmacy preparation and device programming can also be involved in the occurrence of these complications, while device failure is much less of an issue.
