To assess the prognostic value of pre-/post-radiotherapy (pre-/post-RT) radiologic lymph node (LN) features in human papillomavirus (HPV)-positive and HPV-negative oropharyngeal carcinoma (OPC) patients treated with definitive (chemo-)RT.

Clinical node-positive OPCs treated from 2011 to 2015 were reviewed. Nodal features were reviewed by a radiologist on pre-/post-RT computed tomography (CTs). Univariable analysis calculated hazard ratio (HR) for regional failure (RF), distant metastasis (DM), and deaths. Multivariable analysis estimated adjusted HR (aHR) of significant nodal features identified in univariable analysis adjusting for confounders.

Pre-RT CT was undertaken in 344 HPV-positive and 94 HPV-negative OPC patients, of whom 242 (70%) HPV-positive and 67 (71%) HPV-negative also had a post-RT CT. Median follow-up was 4.9 years. Pre-RT LN calcification (pre-RT_LN-cal) increased the risk of RF in HPV-negative (aHR 5.3, P = .007) but not HPV-positive patients (P = .110). Tamoxifen Pre-RT radiologic extranodal extension (pre-RT_rENE+) increased the risk of DM and death in both HPV-negative (DM aHR 6.6, P < .001; death aHR 2.1, both P = .019) and HPV-positive patients (DM aHR 4.9; death aHR 3.0, both P < .001). Increased risk of RF occured with < 20% post-RT LN size reduction in both HPV-negative (HR 6.0, P = .002) and HPV-positive cases (HR 3.0, P = .049). Post-RT_LN-cal did not affect RF, DM, or death regardless of tumor HPV status (all P > .05).

Pre-RT_LN-cal is associated with higher RF risk in HPV-negative but not in HPV-positive patients. Pre-RT_rENE increases risk of DM and death regardless of tumor HPV status. Minimal post-RT LN size reduction (< 20%) increases risk of RF in both diseases. Post-RT_LN-cal + has no apparent influence on outcomes in either disease.

Intra-articular analgesics are increasingly being used after temporomandibular joint (TMJ) arthrocentesis but without clear evidence on its efficacy. The aim of this study was to review the role of intra-articular analgesic injected after TMJ arthrocentesis in improving post-operative outcomes.

PubMed, Embase, Scopus, BioMed Central, CENTRAL and Google Scholar databases were searched from inception up to 15th April 2020. Randomised controlled trials (RCTs) on adult patients with temporomandibular joint disorders (TMDs) comparing any intra-articular analgesic with control after arthrocentesis were included. Risk of bias was assessed by Cochrane Collaboration's Risk of Bias-2 tool.

Nine RCTs were included. Four studies used non-steroidal anti-inflammatory drugs (NSAIDs) and five used opioids after arthrocentesis. Descriptive analysis of NSAID studies indicated that intra-articular NSAIDs may not improve pain and maximal mouth opening (MMO) after TMJ arthrocentesis. Meta-analysis indicated a statistically provide better evidence.Smooth muscle dysfunction in Duchenne muscular dystrophy (DMD) has been rarely studied. A cross-sectional study was conducted to estimate the prevalence of smooth muscle dysfunction (vascular, upper gastrointestinal, and bladder smooth muscle) in children with DMD using questionnaires (Pediatric Bleeding Questionnaire, Pediatric Gastroesophageal Symptom Questionnaire, and Dysfunctional Voiding Symptom Score). Investigations included bleeding time estimation, nuclear scintigraphy for gastroesophageal reflux, and uroflowmetry for urodynamic abnormalities. Ninety-nine subjects were included in the study. The prevalence of vascular, upper gastrointestinal, and bladder smooth muscle dysfunction was 27.2%. Mean bleeding time was prolonged by 117.5 seconds. The prevalence of gastroesophageal reflux was 21%. Voided volume/estimated bladder capacity over 15% and abnormal flow curves on uroflowmetry were seen in 18.2% and 9.7% of the subjects, respectively. Our study highlights the need for addressing issues related to smooth muscle dysfunction in the routine clinical care of patients with DMD.
Methods for pharmacoepidemiologic studies of large-scale data repositories are established. Although clinical cohorts of older adults often contain critical information to advance our understanding of medication risk and benefit, the methods best suited to manage medication data in these samples are sometimes unclear and their degree of validation unknown. We sought to provide researchers, in the context of a clinical cohort study of delirium in older adults, with guidance on the methodological tools to use data from clinical cohorts to better understand medication risk factors and outcomes.

Prospective cohort study.

The Successful Aging After Elective Surgery (SAGES) prospective cohort.

A total of 560 older adults (aged ≥70 years) without dementia undergoing elective major surgery.

Using the SAGES clinical cohort, methods used to characterize medications were identified, reviewed, analyzed, and distinguished by appropriateness and degree of validation for characterizing pharmacoepidemiologic data i vary in the rigor by which they have been developed and validated.
As highlighted in the SAGES cohort, the methods used to classify and analyze medication data in clinically rich cohort studies vary in the rigor by which they have been developed and validated.
Surgeons play a pivotal role in combating the opioid crisis that currently grips the United States. Changing surgeon behavior is difficult, and the degree to which behavioral science can steer surgeons toward decreased opioid prescribing is unclear.

This was a single-institution, single-arm, pre- and postintervention study examining the prescribing of opioids by urologists for adult patients undergoing prostatectomy or nephrectomy. The primary outcome was the quantity of opioids prescribed in oral morphine equivalents (OMEs) after hospital discharge. The primary exposure was a multipronged behavioral intervention designed to decrease opioid prescribing. The intervention had 3 components 1) formal education, 2) individual audit feedback, and 3) peer comparison performance feedback. There were 3 phases to the study a pre-intervention phase, an intervention phase, and a washout phase.

Three hundred eighty-two patients underwent prostatectomy, and 306 patients underwent nephrectomy. The median OMEs decreased from 195 to 19 in the prostatectomy patients and from 200 to 0 in the nephrectomy patients (P < .
