Context: Unrelieved cancer pain at the end of life interferes with achieving patient-centered goals.
Objective: To compare effects of usual hospice care and PAINRelieveIt® on pain outcomes in patients and their lay caregivers.
Methods: In a five-step, stepped-wedge randomized, controlled study, 234 patients (49% male, 18% Hispanic, 51% racial minorities) and 231 lay caregivers (26% male, 20% Hispanic, 54% racial minorities) completed pre-pain/post-pain measures. They received usual hospice care with intervention components that included a summary of the patient's pain data, decision support for hospice nurses, and multimedia education tailored to the patient's and lay caregiver's misconceptions about pain.
Results: The intervention effect on analgesic adherence (primary outcome) was not significant. Post-test worst pain intensity was significantly higher for the experimental group, but the difference (0.70; CI = [0.12, 1.27]) was not clinically meaningful. There was nearly universal availability of prescriptions for strong opioids and adjuvant analgesics for neuropathic pain in both groups. Lay caregivers' pain misconceptions (0-5 scale) were significantly lower in the experimental group than the usual care group (mean difference controlling for baseline is 0.38; CI = [0.08, 0.67]; P = 0.01).
Conclusion: This randomized controlled trial was a negative trial for the primary study outcomes but positive for a secondary outcome. The trial is important for clearly demonstrating the feasibility of implementing the innovative set of interventions.

Background: Prophylactic parenteral administration of antibiotics is strongly recommended to prevent surgical site infection (SSI). Cefoxitin is mainly administered intravenously in colorectal surgery. The current standard method for administering prophylactic antibiotics in adults is to administer a fixed dose quickly before skin incision.

AIM- The objective of the systematic review is to evaluate the incidence of postoperative pain after single-visit and multiple-visit root canal therapy. METHODS- Published research indexed in PubMed or Scopus or Cochrane or DOAJ or Web of Science evaluating the frequency percentage of postoperative aching after one and several root canal therapy appointments through randomized controlled trials or prospectively were included. RESULT- Most surveys utilized VAS (Visual Analogue Scale) to estimate the degree of pain among the participants.

Various interventions are available for the management, of which microinvasive techniques such as infiltration, sealants, glass ionomers, are novel and convenient. The purpose of this systematic review and meta-analysis was to compare microinvasive techniques with noninvasive or invasive treatment modalities in terms of effectiveness in halting interproximal caries lesion progression radiographically assessed.

Background: Postoperative pain remains a significant problem in patients undergoing donor nephrectomy despite reduced tissue trauma following laparoscopic living donor nephrectomy (LLDN). Inadequately treated pain leads to physiological and psychological consequences, including chronic neuropathic pain.
Materials And Methods: This randomized controlled double-blinded trial was conducted in sixty-nine (n = 69) participants who underwent LLDN under general anesthesia.
