Frailty, Myelopathy, and Enhanced Recovery After Surgery (ERAS) in Patients Undergoing Posterior Cervical Fusion (PCF).

BACKGROUND: The Enhanced Recovery After Surgery (ERAS) protocol is a proven method to improve postsurgical outcomes. While recent studies have shown the benefit of ERAS even in frail patient populations, myelopathy is another factor affecting outcomes in patients undergoing Posterior Cervical Fusion (PCF). This study evaluated the benefit of an ERAS protocol in frail patients undergoing PCF. METHODS: A retrospective chart review identified consecutive patients undergoing PCF by a single surgeon from August 2015-July 2021, with implementation of ERAS in December 2018. Outcome measures included length of stay (LOS), non-home discharge disposition, complications, return of physiologic function, and severe pain score. A mFI-5 score of ≥ 2 and a Nurick score of ≥ 3 defined frail and myelopathic patients, respectively. Univariate analysis (p<0.05) and multivariate analyses, using mixed-effect models, (p<0.0125), were performed. RESULTS: There were a total of 174 patients, 71 frail (41%). Of the frail patients, 61% were also myelopathic and 56% underwent ERAS. Of the non-frail patients, 43% were myelopathic and 57% underwent ERAS. On univariate analyses, frail patients with ERAS had less drains placed (p<0.0001), decreased urinary retention (p=0.0002), decreased LOS (p=0.013), and were less likely to have a non-home discharge (p=0.001). On multivariate analysis, LOS (p=0.0003), time to return of physiologic function (p=0.004), complications (p=0.001), and non-home discharges (p<0.0001) were decreased with ERAS, irrespective of groups. CONCLUSIONS: ERAS is an effective protocol in PCF patients that may expedite return of physiologic function, lessen LOS, decrease the number of non-home discharges, and reduce complications, irrespective of frailty or myelopathy status.

Efficacy-based comparison between adults and children regarding using advanced counseling for asthma.

BACKGROUND: Asthma advanced counseling using smartphone applications has recently become one of the most effective and commonly used methods among adults and children with asthma. OBJECTIVES: We aimed to compare the advanced counseling effectiveness between adults and children with asthma. METHODS: A cohort prospective parallel study was performed on a group of adults and children nonsmoking patients with asthma, using a pressurized metered dose inhaler (pMDI). The patients were divided into two groups namely adults with asthma with ages ranging from 19 to 60 years and Children with asthma with ages ranging from 11 to 18 years, the two groups received a 2-month course of advanced counseling using "Asthma software" and "Asthma Dodge" smartphone applications, during which the two groups were monitored using the forced expiratory volume in the first second to the forced vital capacity (FEV1/FVC) ratio and asthma control test (ACT). The study has obtained ethical approval with the serial number REC-H-PhBSU-23002, adhering to the principles outlined in The Declaration of Helsinki, from the Ethical Approval Committee of Beni-Suef University Faculty of Pharmacy. RESULTS: With a total of 60 patients with asthma (N = 60), 31 adults (N = 31), and 29 children (N = 29), We found that starting from the first-month visit of counseling the children group showed superiority over the adult group in terms of the pulmonary function improvement p = .006. Also, regarding ACT scores the children group showed a superiority over the adult group this significance started from the first-month visit and continued to the second-month visit with p values = .032 and .011, respectively. CONCLUSION: The advanced counseling achieved better asthma control and pulmonary function improvement in children and adults; however, the improvement was much better in children with asthma than adults with asthma.

Obstructive Sleep Apnea and Stroke: Determining the Mechanisms Behind their Association and Treatment Options.

Sleep-disordered breathing (SDB) can be a sequela of stroke caused by vascular injury to vital respiratory centers, cerebral edema, and increased intracranial pressure of space-occupying lesions. Likewise, obstructive sleep apnea (OSA) contributes to increased stroke risk through local mechanisms such as impaired ischemic cerebrovascular response and systemic effects such as promoting atherosclerosis, hypercoagulability, cardiac arrhythmias, vascular-endothelial dysfunction, and metabolic syndrome. The impact of OSA on stroke outcomes has been established, yet it receives less attention in national guidelines on stroke management than hyperglycemia and blood pressure dysregulation. Furthermore, whether untreated OSA worsens stroke outcomes is not well-described in the literature. This scoping review provides an updated investigation of the correlation between OSA and stroke, including inter-relational pathophysiology. This review also highlights the importance of OSA treatment and its role in stroke outcomes. Knowledge of pathophysiology, the inter-relationship between these common disorders, and the impact of OSA therapy on outcomes affect the clinical management of patients with acute ischemic stroke. In addition, understanding the relationship between stroke outcomes and pre-existing OSA will allow clinicians to predict outcomes while treating acute stroke.

Application of different counseling strategies for better adult asthma control.

OBJECTIVE: We aimed to compare the effectiveness of three distinct counseling methods to determine the most effective approach. METHODS: In this prospective cohort study with a two-month follow-up, A group of non-smoking adults, aged 19-60 years, were randomly collected at outpatients clinic with prior asthma diagnosis, based on the forced expiratory volume in one seconds to forced vital capacity ratio (FEV1/FVC) and the guidelines outlined by the Global Initiative for Asthma (GINA), At the baseline assessment, all patients, underwent FEV1/FVC measurements, asthma symptom evaluations using Asthma Control Test (ACT), Asthma Control Questionnaire (ACQ), and GINA symptoms control assessment questionnaire, and assessment of pressurized metered-dose inhaler (pMDI) usage. The patients were divided into three groups, each assigned a distinct counseling strategy: traditional verbal counseling, advanced counseling utilizing the Asthma smartphone-application, and a combination of advanced-verbal counseling. We conducted a two-month monitoring period for all three groups. RESULTS: Significant differences (p < .001) were observed among the three counseling groups in ACT, FEV1/FVC ratio, and GINA symptoms control assessment scores from the first month to the second month visit. Regarding ACQ, the study unveiled a noteworthy disparity in ACQ scores during the second week, with a significant difference (p = .025) observed between the verbal and advanced-verbal counseling groups. Similarly, a significant difference (p = .016) was noted between the advanced counseling group and the advanced-verbal counseling groups. CONCLUSION: The study findings indicate that the combining advanced-verbal counseling by incorporating the Asthma smartphone-application alongside traditional verbal counseling is a more effective approach for improving asthma control in adults.

The Impact of Multimodal Prehabilitation on Patient-Reported Outcomes for a Frail Octogenarian Undergoing Multilevel Lumbar Spinal Fusion Surgery: A Case Report.

This case report presents the perioperative optimization pathway of a frail octogenarian who underwent multilevel lumbar spinal fusion surgery. This patient was enrolled in a multimodal prehabilitation program for frail older adults. The multimodal prehabilitation program includes preoperative interventions that prevent further decline in physiological functions before spine surgery. The program focuses on physical exercise, nutritional intervention, and pain neuroscience education. Six weeks postoperatively, clinical and patient-reported outcomes improved in the categories targeted by the preoperative interventions and surgery. This report suggests that prehabilitation is feasible for preoperatively optimizing frail older adults undergoing complex spine surgery.

Safety and efficacy of intralesional injection of enalapril versus triamcinolone acetonide in the treatment of keloids.

INTRODUCTION: Keloids are pathologic conditions characterized by fibroblast hyper-proliferation and excess collagen deposition. Enalapril, one of the angiotensin-converting enzyme inhibitors, has recently been highlighted as a new therapeutic modality in treating keloids. This study evaluates the effectiveness of intralesional injection of enalapril versus triamcinolone acetonide (TAA) in keloids. METHODS: Forty patients with multiple keloids were enrolled in our study. Enalapril and TAA were injected intralesionally in one session per month for three sessions. The clinical outcomes were assessed via the Vancouver Scar Scale (VSS) and the Patient and Observer Scar Assessment Scale (POSAS). RESULTS: In both groups, according to VSS and POSAS, there was a high statistically significant difference (p-value ≤ 0.01) before treatment, at the end of each session, and 3 months after treatment. There was no significant difference between both groups regarding degree of improvement. Patients treated with TAA developed more significant complications than those in the enalapril group (p-value < 0.05). CONCLUSIONS: Both enalapril and TAA had the same clinical effect. Enalapril could be a safe alternative to steroids in the treatment of keloid and hypertrophic scars. Further studies on enalapril are needed on a large sample of patients with further focus on the mechanism of this innovative drug.

Variability of neonatal premedication practices for endotracheal intubation and LISA in the UK (NeoPRINT survey).

OBJECTIVE: The NeoPRINT Survey was designed to assess premedication practices throughout UK NHS Trusts for both neonatal endotracheal intubation and less invasive surfactant administration (LISA). DESIGN: An online survey consisting of multiple choice and open answer questions covering preferences of premedication for endotracheal intubation and LISA was distributed over a 67-day period. Responses were then analysed using STATA IC 16.0. SETTING: Online survey distributed to all UK Neonatal Units (NNUs). PARTICIPANTS: The survey evaluated premedication practices for endotracheal intubation and LISA in neonates requiring these procedures. MAIN OUTCOME MEASURES: The use of different premedication categories as well as individual medications within each category was analysed to create a picture of typical clinical practice across the UK. RESULTS: The response rate for the survey was 40.8 % (78/191). Premedication was used in all hospitals for endotracheal intubation but overall, 50 % (39/78) of the units that have responded, use premedications for LISA. Individual clinician preference had an impact on premedication practices within each NNU. CONCLUSION: The wide variability on first-line premedication for endotracheal intubation noted in this survey could be overcome using best available evidence through consensus guidance driven by organisations such as British Association of Perinatal |Medicine (BAPM). Secondly, the divisive view around LISA premedication practices noted in this survey requires an answer through a randomised controlled trial.

The Enhanced Recovery After Surgery pathway for posterior cervical surgery: a retrospective propensity-matched cohort study.

OBJECTIVE: The Enhanced Recovery After Surgery (ERAS) protocol is a comprehensive, multifaceted approach aimed at improving postoperative outcomes. It incorporates a range of strategies to promote early and more effective recovery, including reducing pain, complications, and length of stay, without increasing readmission rate. To date, ERAS for spine surgery patients has been primarily limited to lumbar surgery and anterior cervical decompression and fusion (ACDF). ERAS has not been previously studied for posterior cervical surgery, which may present a greater opportunity for improvement in patient outcomes with ERAS than ACDF. This single-institution, multi-surgeon study assessed the impact of an ERAS protocol in patients undergoing posterior cervical decompression surgery. METHODS: This study included a retrospective consecutive patient cohort with controls that were propensity matched for age, body mass index, sex, home opioid use, surgical levels, Nurick grade, and smoking status. In addition, consecutive patients who underwent posterior cervical decompression surgery for degenerative disease from December 2014 to December 2021 were included. ERAS was implemented in December 2018. Demographic, perioperative, clinical, and radiographic information was gathered. Regression models were created to evaluate length of stay, physiological function, pain levels, and opioid use. The primary focus was length of stay, with secondary outcomes including timing of ambulation, bowel movement, and voiding; daily pain scores; opioid consumption; discharge status; 30-day readmission rates; and reoperation rates. RESULTS: There were 366 patients included in the study, all of whom were included in multivariate models, and 254 (127 in each cohort) were included on the basis of matching. After propensity matching, patient characteristics, operative procedures, and operative duration were similar between groups. The ERAS cohort had a significantly improved length of stay (3.2 vs 4.7 days, p < 0.0001) and home discharge rate (80% vs 50%, p < 0.001) without an increase in readmission rate. The ERAS cohort had an earlier day of the first ambulation (p = 0.003), bowel movement (p = 0.014), and voiding (p = 0.001). ERAS demonstrated a significantly lower composite complication rate (1.1 vs 1.8, p < 0.0001). ERAS resulted in better maximum pain scores (p = 0.043) and trended toward improved mean pain scores (p = 0.072), although total opioid use was similar. CONCLUSIONS: Implementing a novel ERAS protocol significantly improved length of stay, return of physiological function, home discharge, complications, and maximum pain score after posterior cervical surgery.

Frailty Assessment and Prehabilitation Before Complex Spine Surgery in Patients With Degenerative Spine Disease: A Narrative Review.

Degenerative spine disease increases in prevalence and may become debilitating as people age. Complex spine surgery may offer relief but becomes riskier with age. Efforts to lessen the physiological impact of surgery through minimally invasive techniques and enhanced recovery programs mitigate risk only after the decision for surgery. Frailty assessments outperform traditional tools of perioperative risk stratification. The extent of frailty predicts complications after spine surgery such as reoperation for infection and 30-day mortality, as well as elements of social cost such as hospital length of stay and discharge to an advanced care facility. Symptoms of spine disease overlap with phenotypic markers of frailty; therefore, different frailty assessment tools may perform differently in patients with degenerative spine disease. Beyond frailty, however, cognitive decline and psychosocial isolation may interact with frailty and affect achievable surgical outcomes. Prehabilitation, which has reduced perioperative risk in colorectal and cardiac surgery, may benefit potential complex spine surgery patients. Typical prehabilitation includes physical exercise, nutrition supplementation, and behavioral measures that may offer symptomatic relief even in the absence of surgery. Nonetheless, the data on the efficacy of prehabilitation for spine surgery remains sparse and barriers to prehabilitation are poorly defined. This narrative review concludes that a frailty assessment-potentially supplemented by an assessment of cognition and psychosocial resources-should be part of shared decision-making for patients considering complex spine surgery. Such an assessment may suffice to prompt interventions that form a prehabilitation program. Formal prehabilitation programs will require further study to better define their place in complex spine care.

The BUDDYS System: A Unique Peer Support Strategy Among Anaesthesiology Residents During the COVID-19 Pandemic.

OBJECTIVE: The coronavirus disease 2019 pandemic stressed healthcare organizations. Initial efforts focused on supplies with a minimal empha- sis on frontline healthcare workers' wellbeing. Anaesthesiology residents represent vulnerable frontline healthcare workers because airway pro- cedures increase nosocomial infection risks. Peer support can promote healthcare workers' wellbeing during crises; its application to graduate medical trainees is underrepresented in the literature. We implemented a quality improvement project to improve wellbeing among anaesthesiol- ogy residents via a peer support system called BUilding Dynamic Duos for Your Support. METHODS: BUilding Dynamic Duos for Your Support consists of pairing 2 anaesthesiology residents with instructions to support each other in anticipation of a coronavirus disease 2019 case surge. A lecture presentation introduced this system to the residents and described frequent check-ins with another resident. We evaluated the initiative with a survey 2-4 weeks postimplementation. RESULTS: BUilding Dynamic Duos for Your Support began in April 2020 and involved 88 residents. Survey respondents (n = 58) indicated that BUilding Dynamic Duos for Your Support had a positive impact on their wellbeing. BUilding Dynamic Duos for Your Support implementation had no additional costs, requiring minimal resource dedication. CONCLUSIONS: BUilding Dynamic Duos for Your Support promoted wellbeing among anaesthesiology trainees. This quality improvement project highlights the positive impact of a peer support system on anaesthesiology residents' wellbeing with a potential broader application to graduate medical education.

Airway Management During Cardiopulmonary Resuscitation.

Purpose of the review: This review summarizes the updated literature on airway management during cardiopulmonary resuscitation (CPR). It provides guidance for clinicians to carefully incorporate the most recent recommendations related to airway management, oxygenation, and ventilation both during CPR and after return of spontaneous circulation. Recent Findings: The American Heart Association and the International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care provide updated recommendations related to airway management during CPR, which focus on advanced airway strategies in out-of-the hospital cardiac arrest and in-hospital cardiac arrest. There is no evidence that any single advanced airway technique is superior to the other in terms of survival and neurological outcomes. There is controversy as to whether early advanced airway management could lead to favorable outcome. Summary: Advanced airway strategies and alternatives to airway management (including passive oxygenation) can be utilized in different settings while minimizing interruption in chest compressions.

Enhanced recovery after surgery (ERAS) improves return of physiological function in frail patients undergoing one- to two-level TLIFs: an observational retrospective cohort study.

BACKGROUND CONTEXT: The enhanced recovery after surgery (ERAS) protocol is a multimodal approach which has been shown to facilitate recovery of physiological function, and reduce early post-operative pain, complications, and length of stay (LOS) in open one- to two-level TLIF. The benefit of ERAS in specifically frail patients undergoing TLIF has not been demonstrated. Frailty is clinically defined as a syndrome of physiological decline that can predispose patients undergoing surgery to poor outcomes. PURPOSE: This study primarily evaluated the benefit of an ERAS protocol in frail patients undergoing one- or two-level open TLIF compared to frail patients without ERAS. Secondarily, we assessed whether outcomes in frail patients with ERAS approximated those seen in nonfrail patients with ERAS. STUDY DESIGN: Retrospective consecutive patient cohort with controls propensity-matched for age, body mass index, sex, and smoking status. PATIENT SAMPLE: Consecutive patients that underwent one- or two-level open TLIF for degenerative disease from August, 2015 to July, 2021 by a single surgeon. ERAS was implemented in December 2018. OUTCOME MEASURES: Primary outcome measure was return of postoperative physiological function defined as the summation of first day to ambulate, first day to bowel movement, and first day to void. Additional outcome measures included LOS, daily average pain scores, opioid use, discharge disposition, 30-day readmission rate, and reoperation. METHODS: A retrospective analysis of frail patients > 65 years of age undergoing one- to two-level open TLIF post-ERAS were compared to propensity matched frail pre-ERAS patients. Frailty was assessed using the Fried phenotype classification (score >1). Patient demographics, LOS, first-day-to-ambulate (A1), first-day-to-bowel movement (B1), first-day-to-void (V1) were collected. Return of physiological function was defined as A1+B1+V1. Primary analysis was a comparison of frail patients pre-ERAS versus post-ERAS to determine effect of ERAS on return of physiologic function with frailty. Secondary analysis was a comparison of post-ERAS frail versus post-ERAS nonfrail patients to determine if return of physiologic function in frail patients with ERAS approximates that of nonfrail patients. RESULTS: In the primary analysis, 32 frail patients were included with mean age ± standard deviation of 72.8±4.4 years, mean BMI 28.8±5.5, 65.6% were male, 15 pre-ERAS and 17 post-ERAS. Patient characteristics were similar between groups. After ERAS implementation, return of physiological function improved by a mean 3.2 days overall (post-ERAS 3.4 vs. pre-ERAS 6.7 days) (p<.0001), indicating a positive effect of ERAS in frail patients. Additionally, length of stay improved by 1 day (4.8±1.6 vs. 3.8±1.9 days, p<.0001). Total daily intravenous morphine milligram equivalent (MME) as well as average daily pain scores were similar between groups. Secondarily, 26 nonfrail patients post ERAS were used as a comparison group with the 17 post-ERAS frail cohort. Mean age of this cohort was 73.4±4.6 years, mean BMI 27.4±4.9, and 61.9% were male. Return of physiologic function was similar between cohorts (post-ERAS nonfrail 3.5 vs. post-ERAS frail 3.4 days) (p=.938), indicating the benefit with ERAS in frail patients approximates that of nonfrail patients. CONCLUSIONS: ERAS significantly improves return of physiologic function and length of stay in patients with frailty after one- to two-level TLIF, and approximates improved outcomes seen in non-frail patients.

Enhanced recovery after surgery (ERAS) for open transforaminal lumbar interbody fusion: a retrospective propensity-matched cohort study.

BACKGROUND: The enhanced recovery after surgery (ERAS) protocol is a multidisciplinary, multimodal approach which has been shown to facilitate recovery of physiological function, and reduce postoperative pain, complication rates, and length of stay without adversely affecting readmission rates. Design and implementation of ERAS protocols in the recent spine surgery literature has primarily focused on patients undergoing minimally invasive lumbar surgery. However, conventional open transforaminal lumbar interbody fusion (TLIF) remains a common procedure and to date there are no studies assessing an ERAS protocol in this patient population. PURPOSE: This study presents a single surgeon experience implementing an ERAS protocol in patients undergoing 1- or 2-level open TLIF. STUDY DESIGN/SETTING: Retrospective consecutive patient cohort with controls propensity-matched for age, body mass index, sex, and smoking status. PATIENT SAMPLE: Consecutive patients that underwent 1- or 2-level open TLIF for degenerative disease from 12/2018 - 02/2021 and controls from 12/2011-12/2017 by a single surgeon. ERAS was implemented in December 2018. OUTCOME MEASURES: Primary: length of stay; Secondary: first day to ambulate, first day to bowel movement, first day to void, daily average and maximum pain scores, opioid use, discharge disposition, 30-day readmission rate, and re-operations. METHODS: Demographic, perioperative, clinical, radiographic data were collected. Multivariate mixed-linear regression models were developed for length of stay, physiological function, pain scales, and opiate use. RESULTS: There were 114 patients included with 57 in each cohort. After propensity matching, patient characteristics were similar between groups. Operative time decreased significantly after institution of ERAS (170±44 vs. 141±37 minutes, p <.0001) as did length of stay (4.6±1.7 vs. 3.6±1.6 days, p<.0001). First day of ambulation, bowel movement, and bladder voiding improved by 0.8 (p<.0001), 0.7 (p=.008), and 0.8 (p<.0001) days, respectively, in the ERAS cohort. Total daily intravenous morphine milligram equivalent (MME) (8±9 vs. 36±38, p<0.0001) and total 72-hour MME consumption (53±33 vs. 68±48, p<.0001) was significantly lower in the ERAS cohort; however, 72-hour MME consumption was not found to be significantly different in a sensitivity analysis controlling for preoperative MME. Average daily pain scores were similar between groups. CONCLUSIONS: Consistent with other studies demonstrating benefit of an ERAS protocol for minimally invasive spine procedures, ERAS was associated with decreased operative time, reduced length of stay, decrease in IV opioid consumption, and improved physiological outcomes for open 1- and 2-level TLIF. ERAS can be a potentially effective strategy for improving patient outcome and efficiency of healthcare resources for common conventional spinal surgeries such as open TLIF.

Prevalence of Toxoplasma gondii 36-KDa antigen and chronic Hepatitis C: another evidence of an Association.

In chronic hepatitis C (CHC), Toxoplasma gondii infection can lead to more severe diseases and is capable of changing the disease course. Former studies were concerning anti-T. gondii IgG/IgM seroprevalence in CHC patients regardless the antigenic proteins that are associated with active infection. Therefore, this study aimed to evaluate association between prevalence of 36-KDa T. gondii antigen (TAg) and both CHC progression and liver and viral biochemical parameters. One hundred-twenty five CHC patients (65 with fibrosis and 60 with cirrhosis) and forty healthy controls constituted this study. Demographics and clinical data were collected. Both TAg and HCV-NS4 were identified using ELISA. In contrast to healthy controls (0%), both seropositivity (P = 0.043) and mean serum level (P = 0.025) of TAg were higher in cirrhotic patients (43.3 %; 1.2 ± 0.2 ng/mL) compared to fibrotic patients (26.2 %; 0.7 ± 0.1 ng/mL). T. gondii infection was significantly (P < 0.05) associated with liver and viral biochemical parameters including increased ALT and AST activities, total bilirubin and AFP levels and decreased albumin and platelets count levels. Interestingly, TAg positivity were associated with elevated HCV-NS4 level compared to negative TAg patients (212.5 ± 25.3 vs. 133.9 ± 17.4 µg/mL (P = 0.026); r = 0.559 (P < 0.0001)). In conclusion, this study highlighted association between T. gondii parasitemia and CHC progression since TAg was more prevalent among cirrhotic than fibrotic patients and healthy controls. The presence of TAg was associated with impaired liver functions and increased HCV-NS4 levels. Further studies are needed to define the mechanism of this association.

Accessing Artificial Intelligence for Clinical Decision-Making.

Advancements in computing and data from the near universal acceptance and implementation of electronic health records has been formative for the growth of personalized, automated, and immediate patient care models that were not previously possible. Artificial intelligence (AI) and its subfields of machine learning, reinforcement learning, and deep learning are well-suited to deal with such data. The authors in this paper review current applications of AI in clinical medicine and discuss the most likely future contributions that AI will provide to the healthcare industry. For instance, in response to the need to risk stratify patients, appropriately cultivated and curated data can assist decision-makers in stratifying preoperative patients into risk categories, as well as categorizing the severity of ailments and health for non-operative patients admitted to hospitals. Previous overt, traditional vital signs and laboratory values that are used to signal alarms for an acutely decompensating patient may be replaced by continuously monitoring and updating AI tools that can pick up early imperceptible patterns predicting subtle health deterioration. Furthermore, AI may help overcome challenges with multiple outcome optimization limitations or sequential decision-making protocols that limit individualized patient care. Despite these tremendously helpful advancements, the data sets that AI models train on and develop have the potential for misapplication and thereby create concerns for application bias. Subsequently, the mechanisms governing this disruptive innovation must be understood by clinical decision-makers to prevent unnecessary harm. This need will force physicians to change their educational infrastructure to facilitate understanding AI platforms, modeling, and limitations to best acclimate practice in the age of AI. By performing a thorough narrative review, this paper examines these specific AI applications, limitations, and requisites while reviewing a few examples of major data sets that are being cultivated and curated in the US.

Congress of Neurological Surgeons Systematic Review and Evidence-Based Guidelines for Perioperative Spine: Preoperative Pulmonary Evaluation and Optimization.

BACKGROUND: There are no current recommendations for preoperative pulmonary evaluation and management of patients undergoing elective spine surgery. OBJECTIVE: The aim of this guideline is to determine preoperative risk factors for perioperative and postoperative pulmonary adverse events and to determine the optimal preoperative evaluation and management of at-risk patients. METHODS: A systematic review of the literature was performed using the National Library of Medicine PubMed database and the Cochrane Library for studies relevant to postoperative pulmonary adverse events in patients undergoing spine surgery. Clinical studies evaluating preoperative patient risk factors and preoperative diagnostic and treatment interventions were selected for review. RESULTS: The literature search yielded 152 abstracts relevant to the PICO (patient/population, intervention, comparison, and outcomes) questions included in this chapter. The task force selected 65 articles for full-text review, and 24 were selected for inclusion in this systematic review. Twenty-three articles addressed preoperative patient risk factors. One article addressed preoperative diagnostic studies of pulmonary function. There were no studies meeting the inclusion criteria for preoperative pulmonary treatment. CONCLUSION: There is substantial evidence for multiple preoperative patient factors that predict an increased risk of a postoperative pulmonary adverse event. Individuals with these risk factors (functional dependence, advanced age [≥65 yr], chronic obstructive pulmonary disease, congestive heart failure, weight loss, and obstructive sleep apnea) who are undergoing spine surgery should be counseled regarding the potential increased risk of a perioperative and postoperative pulmonary adverse events. There is insufficient evidence to support any specific preoperative diagnostic test for predicting the risk of postoperative pulmonary adverse events or any treatment intervention that reduces risk. It is suggested, however, to consider appropriate preoperative pulmonary diagnostic testing and treatment to address active pulmonary symptoms of existing or suspected disease.The full guidelines can be accessed at https://www.cns.org/guidelines/browse-guidelines-detail/5-preoperative-pulmonary-evaluation-optimization.

Congress of Neurological Surgeons Systematic Review and Evidence-Based Guidelines for Perioperative Spine: Preoperative Opioid Evaluation.

BACKGROUND: Opioid use disorders in the United States have rapidly increased, yet little is known about the relationship between preoperative opioid duration and dose and patient outcomes after spine surgery. Likewise, the utility of preoperative opioid weaning is poorly understood. OBJECTIVE: The purpose of this evidence-based clinical practice guideline is to determine if duration and dose of preoperative opioids or preoperative opioid weaning is associated with patient-reported outcomes or adverse events after elective spine surgery for degenerative conditions. METHODS: A systematic review of the literature was performed using the National Library of Medicine/PubMed database and Embase for studies relevant to opioid use among adult patients undergoing spine surgery. Clinical studies evaluating preoperative duration, dose, and opioid weaning and outcomes were selected for review. RESULTS: A total of 41 of 845 studies met the inclusion criteria and none were Level I evidence. The use of any opioids before surgery was associated with longer postoperative opioid use, and longer duration of opioid use was associated with worse outcomes, such as higher complications, longer length of stay, higher costs, and increased utilization of resources. There is insufficient evidence to support the efficacy of opioid weaning on postoperative opioid use, improving outcome, or reducing adverse events after spine surgery. CONCLUSION: This evidence-based clinical guideline provides Grade B recommendations that preoperative opioid use and longer duration of preoperative opioid use are associated with chronic postoperative opioid use and worse outcome after spine surgery. Insufficient evidence supports the efficacy of an opioid wean before spine surgery (Grade I).The full guidelines can be accessed at https://www.cns.org/guidelines/browse-guidelines-detail/1-preoperative-opioid-evaluation.
