An artificial intelligence-powered, patient-centric digital tool for self-management of chronic pain: a prospective, multicenter clinical trial.

OBJECTIVE: To investigate how a behavioral health, artificial intelligence (AI)-powered, digital self-management tool affects the daily functions in adults with chronic back and neck pain. DESIGN: Eligible subjects were enrolled in a 12-week prospective, multicenter, single-arm, open-label study and instructed to use the digital coach daily. Primary outcome was a change in Patient-Reported Outcomes Measurement Information Systems (PROMIS) scores for pain interference. Secondary outcomes were changes in PROMIS physical function, anxiety, depression, pain intensity scores and pain catastrophizing scale (PCS) scores. METHODS: Subjects logged daily activities, using PainDrainerTM, and data analyzed by the AI engine. Questionnaire and web-based data were collected at 6 and 12 weeks and compared to subjects' baseline. RESULTS: Subjects completed the 6- (n = 41) and 12-week (n = 34) questionnaires. A statistically significant Minimal Important Difference (MID) for pain interference was demonstrated in 57.5% of the subjects. Similarly, MID for physical function was demonstrated in 72.5% of the subjects. A pre- to post-intervention improvement in depression score was also statistically significant, observed in 100% of subjects, as was the improvement in anxiety scores, evident in 81.3% of the subjects. PCS mean scores was also significantly decreased at 12 weeks. CONCLUSION: Chronic pain self-management, using an AI-powered, digital coach anchored in behavioral health principles significantly improved subjects' pain interference, physical function, depression, anxiety, and pain catastrophizing over the 12-week study period.

A Brief Review on the Novel Therapies for Painful Diabetic Neuropathy.

PURPOSE OF REVIEW: Almost half of people diagnosed with diabetes mellitus will develop painful diabetic neuropathy (PDN), a condition greatly impacting quality of life with complicated pathology. While there are different FDA approved forms of treatment, many of the existing options are difficult to manage with comorbities and are associated with unwanted side effects. Here, we summarize the current and novel treatments for PDN. RECENT FINDINGS: Current research is exploring alternative pain management treatments from the first line options of pregabalin, gabapentin, duloxetine, and amitriptyline which often have side effects. The use of FDA approved capsaicin and spinal cord stimulators (SCS) has been incredibly beneficial in addressing this. In addition, new treatments looking at different targets, such as NMDA receptor and the endocannabinoid system, show promising results. There are several treatment options that have been shown to be successful in helping treat PDN, but often require adjunct treatment or alterations due to side effects. While there is ample research for standard medications, treatments such as palmitoylethanolamide and endocannabinoid targets have extremely limited clinical trials. We also found that many studies did not evaluate additional variables other than pain relief, such as functional changes nor were there consistent measurement methods. Future research should continue trials comparing treatment efficacies along with more quality of life measures.

A Comprehensive Review: Chronic Pain Sequelae in the Presence of Ehlers-Danlos Syndrome.

PURPOSE OF REVIEW: Patients diagnosed with Ehlers-Danlos syndromes (EDS), and especially those with the hypermobility subtype, often experience a diverse range of acute and chronic pain conditions throughout their lifetime. These can present in a variety of different phenotypes and comorbidities, making it difficult to develop structured treatment protocols. This review seeks to summarize the current literature to address old and novel treatments for EDS. RECENT FINDINGS: Historically, medications and surgery have been used to treat patients with EDS but with low efficacy. Newer therapies that have shown promising effects for both decreasing pain and increasing quality of life include physical/occupational therapy, transcutaneous electrical nerve stimulation units, trigger point injections, low-dose naltrexone, and laser therapy. In addition, addressing the psychosocial aspects of pain with EDS through methods like cognitive behavioral therapy and patient education has shown to be vital in minimizing pain. Most research also emphasizes that pain management should not only focus on pain reduction, but on helping reduce symptoms of hypermobility, central sensitization, and fatigue to make an impactful difference. Research on pain in EDS is still limited with good clinical practice guidelines often limited by poor sample size and lack of clinical studies. Treatment options should be structured based on the specific type of pain pathology and presenting symptoms of each patient and their comorbidities. Future research should attempt to prioritize larger sample sizes, clear definitions of EDS subtypes, randomized trials for treatment efficacy, and more studies dedicated to non-musculoskeletal forms of pain.

Novel Therapies for Centralized Pain: a Brief Review.

PURPOSE OF REVIEW: Centralized pain presents a complex pathology that many classic pharmacological agents for pain have not been able to sufficiently treat. To date, there are no clear guidelines for preferred treatment methods or comprehensive protocol that addresses confounding factors in this population. We sought to summarize the current field of knowledge around centrally mediated pain and to understand promising novel therapies. RECENT FINDINGS: Many treatments currently used address not only the centralized pain phenotypem but the impact of central sensitization and the common comorbidities that reside within this population. Some novel therapies with promising evidence include the following: low-dose naltrexone, IV ketamine, acupuncture, aerobic activity, and laser therapy. Non-interventional treatment options include aerobic exercise, cognitive-behavioral therapy, mind-body therapies, virtual reality, and patient education on disease expectations. Much of the literature further emphasizes the importance of patient-level predictors, including factors like pain catastrophizing and social history, on treatment compliance and reported pain relief. We found that there are many potential treatment options for patients with centralized pain, particularly those that can be used as adjunct or combination therapies. The introduction of new approaches should occur in a carefully controlled, titrated manner to avoid exacerbation of pain symptoms. This is successfully conducted through patient-physician communication as this is a highly complex and personalized pain category. Our examination shows that while physicians have many options with proven success, there is a need for studies with longitudinal and larger patient populations to better articulate treatment guidelines.

Patient care in rapid-expansion intensive care units during the COVID-19 pandemic crisis.

BACKGROUND: The coronavirus-2019 (COVID-19) pandemic highlighted the unfortunate reality that many hospitals have insufficient intensive care unit (ICU) capacity to meet massive, unanticipated increases in demand. To drastically increase ICU capacity, NewYork-Presbyterian/Weill Cornell Medical Center modified its existing operating rooms and post-anaesthesia care units during the initial expansion phase to accommodate the surge of critically ill patients. METHODS: This retrospective chart review examined patient care in non-standard Expansion ICUs as compared to standard ICUs. We compared clinical data between the two settings to determine whether the expeditious development and deployment of critical care resources during an evolving medical crisis could provide appropriate care. RESULTS: Sixty-six patients were admitted to Expansion ICUs from March 1st to April 30th, 2020 and 343 were admitted to standard ICUs. Most patients were male (70%), White (30%), 45-64 years old (35%), non-smokers (73%), had hypertension (58%), and were hospitalized for a median of 40 days. For patients that died, there was no difference in treatment management, but the Expansion cohort had a higher median ICU length of stay (q = 0.037) and ventilatory length (q = 0.015). The cohorts had similar rates of discharge to home, but the Expansion ICU cohort had higher rates of discharge to a rehabilitation facility and overall lower mortality. CONCLUSIONS: We found no significantly worse outcomes for the Expansion ICU cohort compared to the standard ICU cohort at our institution during the COVID-19 pandemic, which demonstrates the feasibility of providing safe and effective care for patients in an Expansion ICU.

Effect of Posterior Fossa Decompression for Chiari Malformation-I on Scoliosis.

BACKGROUND/AIMS: Scoliosis is common in patients with Chiari malformation-I (CM-I). This study examined the change in scoliosis severity after posterior fossa decompression (PFD) for CM-I. METHODS: We conducted a retrospective review at a single tertiary center for children undergoing PFD with untreated scoliosis, and identified 17 patients with complete follow-up data and imaging. RESULTS: Overall, scoliosis improved in 7 (41.2%) patients, worsened in 9 (52.9%), and remained unchanged in 1 (5.9%) after PFD (mean follow-up of 7.8 ± 4.1 months). We found that 3 of the 8 (38%) children with early-onset scoliosis eventually needed scoliosis corrective surgery, which was needed in 7 of the 9 (78%) patients with adolescent-onset scoliosis. In addition, only 1 patient (17%) with a preoperative scoliosis curve <35 degrees and 9 patients (82%) with a curve ≥35 degrees required surgery for scoliosis correction despite PFD (p = 0.018). CONCLUSION: In certain patients, PFD for CM-I may lead to improvement or stabilization of scoliosis.

Role of artificial intelligence and machine learning in the diagnosis of cerebrovascular disease.

Introduction: Cerebrovascular diseases are known to cause significant morbidity and mortality to the general population. In patients with cerebrovascular disease, prompt clinical evaluation and radiographic interpretation are both essential in optimizing clinical management and in triaging patients for critical and potentially life-saving neurosurgical interventions. With recent advancements in the domains of artificial intelligence (AI) and machine learning (ML), many AI and ML algorithms have been developed to further optimize the diagnosis and subsequent management of cerebrovascular disease. Despite such advances, further studies are needed to substantively evaluate both the diagnostic accuracy and feasibility of these techniques for their application in clinical practice. This review aims to analyze the current use of AI and MI algorithms in the diagnosis of, and clinical decision making for cerebrovascular disease, and to discuss both the feasibility and future applications of utilizing such algorithms. Methods: We review the use of AI and ML algorithms to assist clinicians in the diagnosis and management of ischemic stroke, hemorrhagic stroke, intracranial aneurysms, and arteriovenous malformations (AVMs). After identifying the most widely used algorithms, we provide a detailed analysis of the accuracy and effectiveness of these algorithms in practice. Results: The incorporation of AI and ML algorithms for cerebrovascular patients has demonstrated improvements in time to detection of intracranial pathologies such as intracerebral hemorrhage (ICH) and infarcts. For ischemic and hemorrhagic strokes, commercial AI software platforms such as RapidAI and Viz.AI have bene implemented into routine clinical practice at many stroke centers to expedite the detection of infarcts and ICH, respectively. Such algorithms and neural networks have also been analyzed for use in prognostication for such cerebrovascular pathologies. These include predicting outcomes for ischemic stroke patients, hematoma expansion, risk of aneurysm rupture, bleeding of AVMs, and in predicting outcomes following interventions such as risk of occlusion for various endovascular devices. Preliminary analyses have yielded promising sensitivities when AI and ML are used in concert with imaging modalities and a multidisciplinary team of health care providers. Conclusion: The implementation of AI and ML algorithms to supplement clinical practice has conferred a high degree of accuracy, efficiency, and expedited detection in the clinical and radiographic evaluation and management of ischemic and hemorrhagic strokes, AVMs, and aneurysms. Such algorithms have been explored for further purposes of prognostication for these conditions, with promising preliminary results. Further studies should evaluate the longitudinal implementation of such techniques into hospital networks and residency programs to supplement clinical practice, and the extent to which these techniques improve patient care and clinical outcomes in the long-term.

The effect of obesity on pain severity and pain interference.

Aim: Obesity is one of the most prevalent comorbidities associated with chronic pain, which can severely interfere with daily living and increase utilization of clinical resources. We hypothesized that a higher level of obesity, measured by BMI, would be associated with increased pain severity (intensity) and interference (pain related disability). Materials & methods: Participant data was pulled from a multisite chronic pain outpatient database and categorized based on BMI. Results: A total of 2509 patients were included in the study. We found significant differences between BMI groups for all pain severity scores (worst, least, average, current) and total pain interference score. Obese patients had significantly higher scores than normal weight patients. Conclusion: We found obesity to be associated with increased pain severity and pain interference.

Intrauterine closure of myelomeningocele is associated with superior long-term quality of life than postnatal closure: a single-center study.

OBJECTIVE: The Management of Myelomeningocele Study (MOMS) established several important benefits of myelomeningocele fetal closure, including decreased need for shunting at 30 months. However, the effects of fetal closure on long-term quality of life (QOL) have not been studied. In this study, the authors aimed to analyze the differences in long-term QOL between children treated with intrauterine repair and those treated with postnatal repair. METHODS: Caregivers of children treated with either intrauterine or postnatal closure at a tertiary acute care hospital between 1997 and 2003 were contacted to participate. The Pediatric Quality of Life Inventory (PedsQL 4.0) and a surgical history questionnaire were administered over the phone. Responses to the QOL survey were reverse scored and linearly transformed to a 0-100 scale, with a higher score indicating better QOL. The Mann-Whitney U-test was used to analyze differences in means. RESULTS: Seventy-four children had MMC repair between 1997 and 2003. Twenty-three (31%) of the patients' families responded to the PedsQL 4.0 questionnaire. Of these 23 children, 11 had intrauterine closure and 12 had postnatal closure. The intrauterine group did not differ in age (median [IQR] 17 years [14-17 years] vs 15 years [14-19 years], p = 0.926), sex (27.3% vs 41.7% male, p = 0.469), or lesion level (p = 0.199) from the postnatal group. Fewer patients in the intrauterine group underwent neurosurgical procedures than those in the postnatal group (55.6% vs 100%, p = 0.018). However, of the children receiving neurosurgical procedures, there was no difference in the number of procedures between the intrauterine and postnatal groups (median [IQR] 4 [2-10.5] vs 2.5 [1.75-6.25], p = 0.458). There was no difference in the percentage of children receiving nonneurosurgical procedures between the two groups (100% vs 100%, p > 0.99). Children who underwent intrauterine closure had significantly higher psychosocial health (median [IQR] 70.0 [56.7-83.3] vs 55.0 [42.1-60.0], p = 0.015) as well as total QOL (median [IQR] 56.5 [55.4-81.5] vs 49.5 [32.9-59.0], p = 0.019) than children with postnatal closure. Physical health was not significantly different between the two groups (median [IQR] 62.5 [37.5-78.1] vs 39.1 [18.8-59.4], p = 0.108). CONCLUSIONS: Relative to postnatal closure, children who underwent intrauterine closure of MMC demonstrated better long-term QOL as measured by psychosocial and overall QOL metrics. Given that not all medical and socioeconomic confounders were adjusted for due to the low sample size, validation of these results in a larger population and across multiple centers is needed.

The Preventable Shunt Revision Rate: A Multicenter Evaluation.

BACKGROUND: The Preventable Shunt Revision Rate (PSRR) was recently introduced as a novel quality metric. OBJECTIVE: To evaluate the PSRR across multiple centers and determine associated variables. METHODS: Nine participating centers in North America provided at least 2 years of consecutive shunt operations. Index surgery was defined as new shunt implantation, or revision of an existing shunt. For any index surgery that resulted in a reoperation within 90-days, index surgery information (demographic, clinical, and procedural) was collected and a decision made whether the failure was potentially preventable. The 90-day shunt failure rate and PSRR were calculated per institution and combined. Bivariate analyses were performed to evaluate individual effects of each independent variable on preventable shunt failure followed by a final multivariable model using a backward model selection approach. RESULTS: A total of 5092 shunt operations were performed; 861 failed within 90 days of index operation, resulting in a 16.9% combined 90-day shunt failure rate and 17.6% median failure rate (range, 8.7%-26.9%). Of the failures, 307 were potentially preventable (overall and median 90-day PSRR, 35.7% and 33.9%, respectively; range, 16.1%-55.4%). The most common etiologies of avoidable failure were infection (n = 134, 44%) and proximal catheter malposition (n = 83, 27%). Independent predictors of preventable failure (P < .05) were lack of endoscopy (odds ratio [OR] = 2.26), recent shunt infection (OR = 3.65), shunt type (OR = 2.06) and center. CONCLUSION: PSRR is variable across institutions, but can be 50% or higher. While the PSRR may never reach zero, this study demonstrates that overall about a third of early failures are potentially preventable.

Examining the need for routine intensive care admission after surgical repair of nonsyndromic craniosynostosis: a preliminary analysis.

OBJECTIVEAt British Columbia Children's Hospital (BCCH), pediatric patients with nonsyndromic craniosynostosis are admitted directly to a standard surgical ward after craniosynostosis surgery. This study's purpose was to investigate the safety of direct ward admission and to examine the rate at which patients were transferred to the intensive care unit (ICU), the cause for the transfer, and any patient characteristics that indicate higher risk for ICU care.METHODSThe authors retrospectively reviewed medical records of pediatric patients who underwent single-suture or nonsyndromic craniosynostosis repair from 2011 to 2016 at BCCH. Destination of admission from the operating room (i.e., ward or ICU) and transfer to the ICU from the ward were evaluated. Patient characteristics and operative factors were recorded and analyzed.RESULTSOne hundred fourteen patients underwent surgery for single-suture or nonsyndromic craniosynostosis. Eighty surgeries were open procedures (cranial vault reconstruction, frontoorbital advancement, extended-strip craniectomy) and 34 were minimally invasive endoscope-assisted craniectomy (EAC). Sutures affected were sagittal in 66 cases (32 open, 34 EAC), coronal in 20 (15 unilateral, 5 bilateral), metopic in 23, and multisuture in 5. Only 5 patients who underwent open procedures (6%) were initially admitted to the ICU from the operating room; the reasons for direct admission were as follows: the suggestion of preoperative elevated intracranial pressure, pain control, older-age patients with large reconstruction sites, or a significant medical comorbidity. Overall, of the 107 patients admitted directly to the ward (75 who underwent an open surgery, 32 who underwent an EAC), none required ICU transfer.CONCLUSIONSOverall, the findings of this study suggest that patients with nonsyndromic craniosynostosis can be managed safely on the ward and do not require postoperative ICU admission. This could potentially increase cost savings and ICU resource utilization.

Nasal saline irrigation in pediatric rhinosinusitis: A systematic review.

OBJECTIVE: To determine the efficacy of nasal saline irrigation (NSI) in reducing symptoms and improving quality of life in pediatric patients with acute (ARS) or chronic (CRS) rhinosinusitis. DATA SOURCES: We searched the PubMed/MEDLINE and Embase electronic databases (indexed January, 1950 through April, 2017). REVIEW METHODS: Studies assessing the efficacy of NSI in pediatric patients with ARS or CRS were selected for analysis. Outcome measures, including symptom scores and parental surveys, were analyzed. Two independent reviewers evaluated each abstract and article. RESULTS: Of the 272 articles identified using our search strategy, only 1 study, focusing on the use of NSI in pediatric ARS, met all inclusion criteria. No studies investigating NSI in pediatric CRS were included for analysis. In general, studies demonstrated significant improvement of symptom scores with the use of NSI in pediatric rhinosinusitis; but, the use of varied outcome measures, control treatments, and NSI delivery made including studies and drawing conclusions difficult. No quantitative meta-analysis could be performed. CONCLUSION: NSI may provide benefit for ARS in children; however, additional high-quality studies with defined outcome measures are needed to determine the quantitative efficacy of this therapy in the pediatric patients with rhinosinusitis-especially in pediatric CRS.
