Clinical patterns and implications of prescription opioid use in a pediatric population for the management of urolithiasis in the emergency room.

Extrapolations from the adult population have suggested that opioids should be avoided in the management of pediatric urolithiasis, but the literature is sparse with regards to actual practice patterns and the downstream implications. We sought to investigate the rate of oral opioid administration for children presenting to the emergency room (ER) with urolithiasis and to identify associations between opioid administration and return visits and persistent opioid use. The TriNetX Research and Diamond Networks were used for retrospective exploratory and validation analyses, respectively. Patients <18 years presenting to the emergency room with urolithiasis were stratified by the receipt of oral opioids. Propensity score matching was performed in a 1:1 fashion. Incident cases of opioid administration and risk ratios (RRs) for a return ER visit within 14 days and the presence of an opioid prescription at 6 to 12 months were calculated. Of the 4672 patients in the exploratory cohort, 11.9% were prescribed oral opioids. Matching yielded a total of 1084 patients. Opioids at the index visit were associated with an increased risk of return visits (RR 1.51, 95% CI 1.04-2.20, P = 0.03) and persistent opioid use (RR 4.00, 95% CI 2.20-7.26, P < 0.001). The validation cohort included 6524 patients, of whom 5.7% were prescribed oral opioids. Matching yielded a total of 722 patients and demonstrated that opioids were associated with an increased risk of return visits (RR 1.50, 95% CI 1.04-2.16, P = 0.03) but not persistent opioid use (RR 1.70, 95% CI 0.79-3.67, P = 0.17). We find that the opioid administration rate for pediatric urolithiasis appears reassuringly low and that opioids are associated with a greater risk of return visits and persistent use.

Association of Long-Term, New-Onset, and Postsurgical Diabetes With Survival in Patients With Resectable Pancreatic Cancer: A Retrospective Cohort Study.

BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) has a poor prognosis. Identifying modifiable risk factors, such as diabetes, is crucial. In the context of PDAC diagnosis, diabetes manifests as long-term (LTD), new-onset (NOD), or postsurgical (PSD) phenotypes. The link between these diabetes phenotypes and PDAC survival is debated. MATERIALS AND METHODS: We performed a retrospective study on patients with resectable PDAC who underwent pancreatectomy at Johns Hopkins Hospital from 2003 to 2017. We utilized the National Death Index and electronic medical records to determine vital status. We categorized diabetes as LTD, NOD, or PSD based on the timing of diagnosis relative to pancreatic resection. Using multivariable Cox models, we assessed hazard ratios (HRs) for survival times associated with each phenotype, considering known PDAC prognostic factors. RESULTS: Of 1556 patients, the 5-year survival was 19% (95% CI, 17-21). No significant survival differences were observed between diabetes phenotypes and non-diabetic patients. NOD and PSD presented nonsignificant increased risks of death (aHR: 1.14 [95% CI, 0.8-1.19] and 1.05 [95% CI, 0.89-1.25], respectively). LTD showed no survival difference (aHR, 0.98; 95% CI, 0.99-1.31). CONCLUSIONS: No link was found between diabetes phenotypes and survival in resectable PDAC patients. Comprehensive prospective studies are required to validate these results.

Association Between Temperature and Inpatient Stone Admission in a Pediatric Population.

Background: Higher temperatures have been associated with increased stone formation and subsequent utilization of hospital resources, including inpatient admission. However, these observations have been derived from the adult population. We sought to examine if this purported association extends to the pediatric population. Methods: We used the 2016 Kids' Inpatient Database to identify nationwide pediatric inpatient admissions related to nephrolithiasis. Temperature data from the National Oceanic and Atmospheric Administration was linked to each admission. Comparative statistics analyzed patient and admission characteristics. Multivariable logistic regression analyzed associations between stone-related admissions and temperature. As a frame of reference, this analysis was replicated using the National Inpatient Sample from 2016 to evaluate associations in the adult population. Results: Of the 2,496,257 pediatric admissions, 8453 (0.33%) were related to nephrolithiasis. Temperatures at the time of stone admission were higher than those during nonstone admission (55.9°F vs 54.8°F, p < 0.001). The stone admission group had a higher proportion of females than the nonstone admission group (64.8% vs 55.4%, p < 0.001). Stone admission was significantly associated with temperature (odds ratio [OR] 1.025 per 10°F, confidence interval [95% CI] 1.003-1.049, p = 0.03) and female gender (OR 1.097, 95% CI 1.027-1.171, p = 0.006). In the adult population, 380,520 out of 30,000,941 patients (1.3%) were admitted with a stone. The effect of temperature on stone admissions was similar to that in the pediatric population (OR 1.020, 95% CI 1.014-1.026, p < 0.001), but women were >20% less likely to be admitted for stones than men (OR 0.770, 95% CI 0.757-0.784, p < 0.001). Conclusions: Increased temperatures were associated with an increased risk of stone-related admission in both the pediatric and adult populations. Females were at increased risk for stone-related admissions during childhood, but this trend reverses in adulthood.

Contemporary considerations in the management and treatment of lower pole stones

ABSTRACT The presence of lower pole stones poses a unique challenge due to the anatomical considerations involved in their management and treatment. Considerable research has been performed to determine the optimal strategy when faced with this highly relevant clinical scenario. Standard options for management include observation, shock wave lithotripsy, retrograde intrarenal surgery, or percutaneous nephrolithotomy. Indeed, each approach confers a distinct set of risks and benefits, which must be placed into the context of patient preference and expected outcomes. The current state of practice reflects a combination of lessons learned from managing calculi not only in the lower pole, but also from other locations within the kidney as well.
