Patient-reported outcomes during telehealth versus in-person follow-up visits for patients treated with extracorporeal shockwave therapy.

BACKGROUND: The limited research describing clinical outcomes using telehealth for management of musculoskeletal conditions is primarily within orthopedic surgery care. OBJECTIVE: To characterize differences in patient reported outcomes using telehealth compared with in-person follow-up visits in patients with Achilles tendinopathy (AT) or plantar fasciitis (PF) treated using extracorporeal shockwave therapy (ESWT). DESIGN: Retrospective chart review. SETTING: Outpatient sports medicine clinic. PATIENTS: 82 patients with AT and 46 patients with PF. INTERVENTIONS: In-person (n = 76) and telehealth (n = 52) follow-up visits. MAIN OUTCOME MEASUREMENTS: Victorian Institute of Sports Assessment-Achilles (VISA-A) for AT and Foot and Ankle Ability Measure (FAAM) for PF as well as billing level. RESULTS: There was significant improvement from baseline to final VISA-A (p < .01) and FAAM (p < .01) following ESWT. No significant difference existed in the proportion of patients who met the minimal clinically important difference based on in-person (71.1%) versus telehealth (71.2%) follow-up (p = .99). The in-person group demonstrated higher billing levels compared to the telehealth group (Level: 3.5 ± 0.6 vs. 2.8 ± 0.7, p < .01). CONCLUSIONS: Given no significant differences in outcomes between two modes of follow-ups, telehealth may serve as an alternative method to guide management of musculoskeletal injuries with ESWT and other procedures.

Long term cost comparisons of radical cystectomy versus trimodal therapy for muscle-invasive bladder cancer.

BACKGROUND: Earlier studies on the cost of muscle-invasive bladder cancer treatments are limited to short-term costs of care. We determined the 2- and 5-year costs associated with trimodal therapy (TMT) vs. radical cystectomy (RC). METHODS: We performed a retrospective cohort study using the Surveillance, Epidemiology, and End Results (SEER)-Medicare database. Total Medicare costs at 2 and 5 years following RC vs. TMT were compared using inverse probability of treatment-weighted propensity score models. RESULTS: A total of 2,537 patients aged 66 to 85 years were diagnosed with clinical stage T2-4a muscle-invasive bladder cancer. Total median costs for patients that received no definitive treatment(s) were $73,780 and $88,275 at 2-and 5-years. Costs were significantly higher for TMT than RC at 2-years ($372,839 vs. $191,363, Median Difference $127,815, Hodges-Lehmann Estimate (H-L) 95% Confidence Interval (CI), $112,663-$142,966) and 5-years ($424,570 vs. $253,651, Median Difference $124,466, H-L 95% CI, $105,711-$143,221). TMT had higher outpatient costs than RC (2-years: $318,221 vs. $100,900; 5-years: $367,092 vs. $146,561) with significantly higher costs with radiology, medications, pathology/laboratory, and other professional services. RC had higher inpatient costs than TMT (2-years: $62,240 vs. $33,631, Median Difference $-29,174, H-L 95% CI, $-32,364-$-25,984; 5-years: $75,499 vs. $45,223, Median Difference $-29,843, H-L 95% CI, $-33,905-$-25,781). CONCLUSIONS AND RELEVANCE: The excess spending associated with trimodal therapy vs. radical cystectomy was largely driven by outpatient expenditures. The relatively high long-term trimodal therapy costs are prime targets for cost containment strategies to optimize future value-based care.

Regulation of telomere homeostasis and genomic stability in cancer by N 6-adenosine methylation (m6A).

The role of RNA methylation on N 6-adenosine (m6A) in cancer has been acknowledged, but the underlying mechanisms remain obscure. Here, we identified homeobox containing 1 (HMBOX1) as an authentic target mRNA of m6A machinery, which is highly methylated in malignant cells compared to the normal counterparts and subject to expedited degradation upon the modification. m6A-mediated down-regulation of HMBOX1 causes telomere dysfunction and inactivation of p53 signaling, which leads to chromosome abnormalities and aggressive phenotypes. CRISPR-based, m6A-editing tools further prove that the methyl groups on HMBOX1 per se contribute to the generation of altered cancer genome. In multiple types of human cancers, expression of the RNA methyltransferase METTL3 is negatively correlated with the telomere length but favorably with fractions of altered cancer genome, whereas HMBOX1 mRNA levels show the opposite patterns. Our work suggests that the cancer-driving genomic alterations may potentially be fixed by rectifying particular epitranscriptomic program.

Impact of a Perioperative Protocol on Length of ICU and Hospital Stay in Complex Spine Surgery.

BACKGROUND: In an attempt to improve patient care, a perioperative complex spine surgery management protocol was developed through collaboration between spine surgeons and neuroanesthesiologists. The aim of this study was to investigate whether implementation of the protocol in 2015 decreased total hospital and intensive care unit (ICU) length of stay (LOS) and complication rates after elective complex spine surgery. MATERIALS AND METHODS: A retrospective cohort study was conducted by review of the medical charts of patients who underwent elective complex spine surgery at an academic medical center between 2012 and 2017. Patients were divided into 2 groups based on the date of their spine surgery in relation to implementation of the spine surgery protocol; before-protocol (January 2012 to March 2015) and protocol (April 2015 to March 2017) groups. Outcomes in the 2 groups were compared, focusing on hospital and ICU LOS, and complication rates. RESULTS: A total of 201 patients were included in the study; 107 and 94 in the before-protocol and protocol groups, respectively. Mean (SD) hospital LOS was 14.8±10.8 days in the before-protocol group compared with 10±10.7 days in the protocol group (P<0.001). The spine surgery protocol was the primary factor decreasing hospital LOS; incidence rate ratio 0.78 (P<0.001). Similarly, mean ICU LOS was lower in the protocol compared with before-protocol group (4.2±6.3 vs. 6.3±7.3 d, respectively; P=0.011). There were no significant differences in the rate of postoperative complications between the 2 groups (P=0.231). CONCLUSION: Implementation of a spine protocol reduced ICU and total hospital LOS stay in high-risk spine surgery patients.

A Positive Cocaine Urine Toxicology Test and the Effect on Intraoperative Hemodynamics Under General Anesthesia.

BACKGROUND: Cocaine has a short biological half-life, but inactive urine metabolites may be detectable for a week following use. It is unclear if patients who test positive for cocaine but have a normal electrocardiogram and vital signs have a greater percentage of hemodynamic events intraoperatively. METHODS: A total of 328 patients with a history of cocaine use who were scheduled for elective noncardiac surgery under general anesthesia were enrolled. Patients were categorized into cocaine-positive versus cocaine-negative groups based on the results of their urine cocaine toxicology test. The primary aim of this study was to evaluate whether asymptomatic cocaine-positive patients had similar percentages of intraoperative hemodynamic events, defined as (1) a mean arterial blood pressure (MAP) of <65 or >105 mm Hg and (2) a heart rate (HR) of <50 or >100 beats per minute (bpm) compared to cocaine-negative patients. The study was powered to assess if the 2 groups had an equivalent mean percent of intraoperative hemodynamic events within specific limits using an equivalence test of means consisting of 2 one-sided tests. RESULTS: The cocaine-positive group had a blood pressure (BP) that was outside the set limits 19.4% (standard deviation [SD] 17.7%) of the time versus 23.1% (SD 17.7%) in the cocaine-negative group (95% confidence interval [CI], 0.5-7.0). The cocaine-positive group had a HR outside the set limits 9.6% (SD 16.2%) of the time versus 8.2% (SD 14.9%) in the cocaine-negative group (95% CI, 4.3-1.5). Adjusted for age, sex, body mass index (BMI), smoking status, and the presence of comorbid hypertension, renal disease, and psychiatric illness, the cocaine-positive and cocaine-negative patients were similar within a 7.5% margin of equivalence for MAP data (ß coefficient = 2%, P = .003, CI, 2-6) and within a 5% margin of equivalence for HR data (ß coefficient = 0.2%, P < .001, CI, 4-3). CONCLUSIONS: Asymptomatic cocaine-positive patients undergoing elective noncardiac surgery under general anesthesia have similar percentages of intraoperative hemodynamic events compared to cocaine-negative patients.

Lumbar Spinal Stenosis and Potential Management With Prostaglandin E1 Analogs.

ABSTRACT: Lumbar spinal stenosis is one of the most commonly diagnosed spinal disorders worldwide and remains a major cause for surgery in older adults. Lumbar spinal stenosis is clinically defined as a progressive degenerative disorder with low back pain and associated neurogenic intermittent claudication. Conservative and surgical management of lumbar spinal stenosis has been shown to be minimally effective on its symptoms. A treatment option that has not been investigated in the United States is the utilization of prostaglandin E1 analogs, which have been used primarily in Japan for the treatment of lumbar spinal stenosis since the 1980s. The vasodilatory and antiplatelet aggregation effects of prostaglandin E1 presumably improve symptoms of lumbar spinal stenosis by increasing blood flow to the spinal nerve roots. This brief report examines the potential vascular pathology of lumbar spinal stenosis, reviews evidence on the use of prostaglandin E1 analog limaprost in Japan for lumbar spinal stenosis, and briefly discusses misoprostol as a possible alternative in the United States. The studies summarized in this report suggest that prostaglandin E1 analogs may provide benefit as a conservative treatment option for patients with lumbar spinal stenosis. However, higher-quality studies conducted in the United States and comparison with other currently used conservative treatments are required before it can be recommended for routine clinical use.
