Does the Application of Topical Vancomycin Reduce Surgical Site Infections in Spine Surgery? A Meta-analysis of Randomized Controlled Trials.

BACKGROUND: Surgical site infections (SSIs) represent a major challenge in spine surgery, leading to severe morbidity, mortality, and increased costs. The local application of antibiotics, particularly vancomycin, has emerged as a potential strategy. Individual randomized controlled trials (RCTs) have disagreed about the efficacy of topical vancomycin in preventing SSIs after spine surgery, and so a meta-analysis that pools data from those RCTs might be helpful to inform clinicians' decisions on the topic. QUESTIONS/PURPOSES: This meta-analysis of RCTs asked: Does intrawound topical vancomycin reduce the risk of (1) SSIs, (2) deep SSIs, and (3) superficial SSIs in patients undergoing spine surgery? METHODS: PubMed, Cochrane, and Google Scholar (pages 1-20) were searched up through March 13, 2024 (search performed on March 13, 2024). Inclusion criteria consisted of English or non-English-language RCTs comparing the implementation of topical vancomycin in spine surgery to its nonuse and assessing its efficacy in preventing SSI, while exclusion criteria consisted of nonrandomized comparative studies, single-arm noncomparative studies, comparative studies based on national databases or from the same center as other included studies, studies posted to preprint servers, studies reporting incomplete/nonrelevant outcomes, and studies adding another SSI preventive measure. The studies were assessed using the Cochrane Risk of Bias tool. Heterogeneity was evaluated by Q tests and I2 statistics. We used a random-effects model when considerable heterogeneity was observed (all SSIs, deep SSIs); otherwise, a fixed-effects model was used (all SSIs subanalysis, superficial SSIs). Furthermore, the fragility index was calculated for each of the assessed outcomes when there was no difference between the two groups to assess how many patients were needed to experience the outcomes for a difference to become present. The studied outcomes were the risks of SSIs, deep SSIs, and superficial SSIs. Deep SSIs were defined by the included trials as SSIs underneath the fascia, otherwise they were considered superficial. Six RCTs representing a total of 2140 patients were included, with 1053 patients in the vancomycin group and 1087 in the control group. Using an alpha of 0.05, our meta-analysis had 80% power to detect a risk difference of 1.5% for the primary outcome between patients who did and did not receive vancomycin. The age of the patients in the vancomycin group ranged from 37 to 52 years, while the age in the control group ranged from 34 to 52 years. The surgical procedures consisted of both instrumented and noninstrumented spinal procedures. Overall, the risk of bias in the included studies was either low or unclear, with none of the studies having a high risk of bias in any of the assessed categories (selection bias, performance bias, detection bias, attrition bias, and reporting bias). RESULTS: We found no difference in the risk of SSI between the vancomycin and control groups (3.0% [32 of 1053] versus 3.9% [42 of 1087], relative risk 0.74 [95% CI 0.35 to 1.57]; p = 0.43). Ten additional patients (4.8% infection risk) in the control group would need to experience an SSI for a difference to be observed between the two groups. We found no difference in the risk of deep SSI between the vancomycin and control groups (1.8% [15 of 812] versus 2.7% [23 of 860], relative risk 0.69 [95% CI 0.24 to 2.00]; p = 0.50). Seven additional patients (3.5% infection risk) in the control group would need to experience a deep SSI for a difference to be observed between the two groups. We found no difference in the risk of superficial SSI between the vancomycin and control groups (1.0% [6 of 620] versus 1.4% [9 of 662], relative risk 0.68 [95% CI 0.25 to 1.89]; p = 0.46). Seven additional patients (2.4% infection risk) in the control group would need to experience a superficial SSI for a difference to be observed between the two groups. CONCLUSION: This meta-analysis of randomized trials examining use of topical vancomycin in spine surgery failed to show efficacy in reducing infection, and thus we do not recommend routine use of topical vancomycin for this indication. Future large-scale trials would be needed if surgeons believe that between-group differences smaller than those for which we were powered here (this meta-analysis had 80% power to detect a between-group difference of 1.5% in infection risk) are clinically important, and large database surveys may be informative in terms of assessing for postoperative adverse events associated with the use of vancomycin powder. LEVEL OF EVIDENCE: Level I, therapeutic study.

Risk of Dislocation and Revision Following Primary Total Hip Arthroplasty in Patients With Prior Lumbar Fusion With Spinopelvic Fixation.

BACKGROUND: The effect of spinopelvic fixation in addition to lumbar spinal fusion (LSF) on dislocation/instability and revision in patients undergoing primary total hip arthroplasty (THA) has not been reported previously. METHODS: The PearlDiver Research Program was used to identify patients aged 30 and above undergoing primary THA who received (1) THA only, (2) THA with prior single-level LSF, (3) THA with prior 2-5 level LSF, or (4) THA with prior LSF with spinopelvic fixation. The incidence of THA revision and dislocation/instability was compared through logistic regression and Chi-squared analysis. All regressions were controlled for age, gender, and Elixhauser Comorbidity Index (ECI). RESULTS: Between 2010 and 2018, 465,558 patients without history of LSF undergoing THA were examined and compared to 180 THA patients with prior spinopelvic fixation, 5,299 with prior single-level LSF, and 1,465 with prior 2-5 level LSF. At 2 years, 7.8% of THA patients with prior spinopelvic fixation, 4.7% of THA patients with prior 2-5 level LSF, 4.2% of THA patients with prior single-level LSF, and 2.2% of THA patients undergoing only THA had a dislocation event or instability (P < .0001). After controlling for length of fusion, pelvic fixation itself was associated with higher independent risk of revision (at 2 years: 2-5 level LSF + spinopelvic fixation: aHR = 3.15, 95% CI 1.77-5.61, P < .0001 vs 2-5 level LSF with no spinopelvic fixation: aOR = 1.39, 95% CI 1.10-1.76, P < .0001). CONCLUSION: At 2 years, spinopelvic fixation in THA patients were associated with a greater than 3.5-fold increase in hip dislocation risk compared to those without LSF, and an over 2-fold increase in THA revision risk compared to those with LSF without spinopelvic fixation. LEVEL OF EVIDENCE: III.

Underweight Patients are at Increased Risk for Complications following Total Hip Arthroplasty.

BACKGROUND: Given the prevalence of obesity in the United States, much of the adult reconstruction literature focuses on the effects of obesity and morbid obesity. However, there is little published data on the effect of being underweight on postoperative outcomes. This study aimed to examine the risk of low body mass index (BMI) on complications after total hip arthroplasty (THA). METHODS: A large national database was queried between 2010 and 2020 to identify patients who had THAs. Using International Classification of Disease codes, patients were grouped into the following BMI categories: morbid obesity (BMI>40), obesity (BMI 30 to 40), normal BMI (BMI 20 to 30), and underweight (BMI<20). There were 58,151 patients identified, including 2,484 (4.27%) underweight patients, 34,710 (59.69%) obese patients, and 20,957 (36.04%) morbidly obese patients. Control groups were created for each study group, matching for age, sex, and a comorbidity index. Complications that occurred within 1 year postoperatively were isolated. Subanalyses were performed to compare complications between underweight and obese patients. Statistical analyses were performed using Pearson Chi-squares. RESULTS: Compared to their matched control group, underweight patients showed increased odds of THA revision (Odds Ratio (OR) = 1.32, P = .04), sepsis (OR = 1.51, P = .01), and periprosthetic fractures (OR = 1.63, P = .01). When directly comparing underweight and obese patients (BMI 30 and above), underweight patients had higher odds of aseptic loosening (OR = 1.62, P = .03), sepsis (OR = 1.34, P = .03), dislocation (OR = 1.84, P < .001), and periprosthetic fracture (OR = 1.46, P = .01). CONCLUSION: Morbidly obese patients experience the highest odds of complications, although underweight patients also had elevated odds for several complications. Underweight patients are an under-recognized and understudied high risk arthroplasty cohort and further research is needed.

Structure and function of PspA and Vipp1 N-terminal peptides: Insights into the membrane stress sensing and mitigation.

The phage shock protein (Psp) response maintains integrity of the inner membrane (IM) in response to extracytoplasmic stress conditions and is widely distributed amongst enterobacteria. Its central component PspA, a member of the IM30 peripheral membrane protein family, acts as a major effector of the system through its direct association with the IM. Under non-stress conditions PspA also negatively regulates its own expression via direct interaction with the AAA+ ATPase PspF. PspA has a counterpart in cyanobacteria called Vipp1, which is implicated in protection of the thylakoid membranes. PspA's and Vipp1's conserved N-terminal regions contain a putative amphipathic helix a (AHa) required for membrane binding. An adjacent amphipathic helix b (AHb) in PspA is required for imposing negative control upon PspF. Here, purified peptides derived from the putative AH regions of PspA and Vipp1 were used to directly probe their effector and regulatory functions. We observed direct membrane-binding of AHa derived peptides and an accompanying change in secondary structure from unstructured to alpha-helical establishing them as bona fide membrane-sensing AH's. The peptide-binding specificities and their effects on membrane stability depend on membrane anionic lipid content and stored curvature elastic stress, in agreement with full length PspA and Vipp1 protein functionalities. AHb of PspA inhibited the ATPase activity of PspF demonstrating its direct regulatory role. These findings provide new insight into the membrane binding and function of PspA and Vipp1 and establish that synthetic peptides can be used to probe the structure-function of the IM30 protein family.

Transcription Regulation and Membrane Stress Management in Enterobacterial Pathogens.

Transcription regulation in a temporal and conditional manner underpins the lifecycle of enterobacterial pathogens. Upon exposure to a wide array of environmental cues, these pathogens modulate their gene expression via the RNA polymerase and associated sigma factors. Different sigma factors, either involved in general 'house-keeping' or specific responses, guide the RNA polymerase to their cognate promoter DNAs. The major alternative sigma54 factor when activated helps pathogens manage stresses and proliferate in their ecological niches. In this chapter, we review the function and regulation of the sigma54-dependent Phage shock protein (Psp) system-a major stress response when Gram-negative pathogens encounter damages to their inner membranes. We discuss the recent development on mechanisms of gene regulation, signal transduction and stress mitigation in light of different biophysical and biochemical approaches.

Antimuscarinics in Older People: Dry Mouth and Beyond.

Many common prescription and over-the-counter medications have antimuscarinic effects. Antimuscarinics are a well recognized cause of dry mouth, with potential to cause other physical and cognitive adverse effects. A comprehensive medication review in a patient presenting with dry mouth can lead to overall health improvements. Scoring systems can be helpful in identifying antimuscarinic drugs and their adverse effects. CPD/Clinical Relevance: Antimuscarinic drug use is prevalent and a common cause of dry mouth. Older people are particularly susceptible to antimuscarinic adverse effects.

A Non-operative Approach of Small Bowel Obstruction in Virgin Abdomens.

We present a compelling case of small bowel obstruction (SBO) in a 38-year-old male with a virgin abdomen, a term used to describe an individual who has not undergone prior abdominal surgery. Despite his fit and healthy status, he presented with symptoms indicative of bowel obstruction. Through a meticulous series of history-taking, comprehensive clinical examinations, and precise imaging studies, we were able to arrive at a conclusive diagnosis. Remarkably, the patient experienced a full recovery solely through conservative management, effectively sidestepping the need for surgical intervention. This case prompts a deeper discussion on the nuanced approaches to SBO in individuals with virgin abdomens. We aim to delve into the comparative merits of conservative versus surgical strategies, considering the latest evidence-based practices to guide our understanding and decision-making in such cases.

Ascending Colon Schwannoma: A Rare Submucosal Tumour.

We present a rare case of schwannoma in the ascending colon of a 60-year-old female with dyslipidemia. A series of diagnostic procedures, including colonoscopy and CT colonography, led to the successful robotic-assisted right hemicolectomy. Histological and immunohistochemical analyses confirmed the diagnosis of schwannoma, and the patient achieved a complete recovery post-surgery.

A Case Study: Incidental Finding of Human Intestinal Spirochetosis in Screening Colonoscopy.

Human intestinal spirochetosis (HIS) is a rare occurrence. We present an interesting case study on an asymptomatic over-60-year-old male who was incidentally discovered to have HIS following a colonoscopy that was conducted for his positive fecal occult blood test (FOBT). Histopathology of the colonic biopsy proved the presence of human intestinal spirochetosis; however, as he was asymptomatic, treatment was not initiated in his case. We discuss here the prevalence, presentation, diagnostic methods, and treatment of colonic HIS.

Electrolyte Disturbances and Repletion in Orthopaedic and Spine Surgery Patients.

Electrolyte derangement, defined as disorders of clinically impactful physiologic ions such as potassium, sodium, calcium, magnesium, and phosphate, has a variety of clinical manifestations. These electrolytes have narrow windows of normal in vivo concentration before neurologic, cardiac, renal, or gastrointestinal consequences occur. Perioperative disturbances in electrolyte concentration can lead to increased morbidity and mortality, longer length of stay, and higher rates of short and medium-term readmission in orthopaedic and spine surgery postoperatively. To prevent electrolyte related complications, careful monitoring and repletion of at-risk patients must be undertaken. A systematic approach to repletion allows for a safe and efficacious treatment of these disorders.

Stakeholder views on the design of National Health Service perinatal mental health services: 360-degree survey.

AIMS AND METHOD: At the start of a new community perinatal mental health service in Scotland we sought the opinions and aspirations of professional and lay stakeholders. A student elective project supported the creation of an anonymous 360-degree online survey of a variety of staff and people with lived experience of suffering from or managing perinatal mental health problems. The survey was designed and piloted with trainees and volunteer patients. RESULTS: A rich variety of opinions was gathered from the 60 responses, which came from a reasonably representative sample. Respondents provided specific answers to key questions and wrote free-text recommendations and concerns to inform service development. CLINICAL IMPLICATIONS: There is clear demand for the new expanded service, with strong support for provision of a mother and baby unit in the North of Scotland. The digital survey method could be adapted to generate future surveys to review satisfaction with service development and generate ideas for further change.

Laminoplasty Versus Laminectomy and Posterior Fusion for Cervical Myelopathy : A Meta-Analysis of Radiographic and Clinical Outcomes.

STUDY DESIGN: Meta-analysis. OBJECTIVE: This meta-analysis investigates the outcomes of laminoplasty (LP) and laminectomy with fusion (LF) to guide effective patient selection for these 2 procedures. BACKGROUND: Although LF traditionally offers the ability for excellent posterior decompression, it may alter cervical spine biomechanics and increase the risk of adjacent segment degeneration. LP aims to preserve the natural kinematics of the spine but has not been universally accepted, and may be associated with inadequate decompression, neck pain, and recurrent stenosis. MATERIALS AND METHODS: PubMed, Cochrane, and Google Scholar (pages 1-20) were searched up until March 2024. The outcomes studied were surgery-related outcomes [operative time (OR) time, estimated blood loss (EBL), and length of stay], adverse events (overall complications, C5 palsy, and reoperations), radiographic outcomes (cervical lordosis, cervical sagittal vertical axis, and T1 slope angle), and patient-reported outcome measures (Neck Disability Index, Visual Analog Scale for neck pain, and Japanese Orthopaedic Association). RESULTS: Twenty-two studies were included in this meta-analysis, of which 19 were retrospective studies, 2 were prospective nonrandomized studies, and 1 was a randomized controlled trial. A total of 2128 patients were included, with 1025 undergoing LP and 1103 undergoing LF. Patients undergoing LP experienced significantly shorter operative time ( P = 0.009), less EBL ( P = 0.02), a lower rate of overall complications ( P < 0.00001) and C5 palsy ( P = 0.003), a lower T1 slope angle ( P = 0.02), and a lower Neck Disability Index ( P = 0.0004). No significant difference was observed in the remaining outcomes. CONCLUSION: This meta-analysis demonstrates that for cervical myelopathy, LP has the benefits of shorter operative time time, less EBL, and reduced incidence of C5 palsy as well as overall complication rate. Given these findings, LP remains an important surgical option with a favorable complication profile in patients with cervical myelopathy, although careful patient selection is still paramount in choosing the right procedure for individual patients. LEVEL OF EVIDENCE: 4.

Large Language Model Prompting Techniques for Advancement in Clinical Medicine.

Large Language Models (LLMs have the potential to revolutionize clinical medicine by enhancing healthcare access, diagnosis, surgical planning, and education. However, their utilization requires careful, prompt engineering to mitigate challenges like hallucinations and biases. Proper utilization of LLMs involves understanding foundational concepts such as tokenization, embeddings, and attention mechanisms, alongside strategic prompting techniques to ensure accurate outputs. For innovative healthcare solutions, it is essential to maintain ongoing collaboration between AI technology and medical professionals. Ethical considerations, including data security and bias mitigation, are critical to their application. By leveraging LLMs as supplementary resources in research and education, we can enhance learning and support knowledge-based inquiries, ultimately advancing the quality and accessibility of medical care. Continued research and development are necessary to fully realize the potential of LLMs in transforming healthcare.

Sacroplasty for Sacral Insufficiency Fractures: Narrative Literature Review on Patient Selection, Technical Approaches, and Outcomes.

Sacral insufficiency fractures commonly affect elderly women with osteoporosis and can cause debilitating lower back pain. First line management is often with conservative measures such as early mobilization, multimodal pain management, and osteoporosis management. If non-operative management fails, sacroplasty is a minimally invasive intervention that may be pursued. Candidates for sacroplasty are patients with persistent pain, inability to tolerate immobilization, or patients with low bone mineral density. Before undergoing sacroplasty, patients' bone health should be optimized with pharmacotherapy. Anabolic agents prior to or in conjunction with sacroplasty have been shown to improve patient outcomes. Sacroplasty can be safely performed through a number of techniques: short-axis, long-axis, coaxial, transiliac, interpedicular, and balloon-assisted. The procedure has been demonstrated to rapidly and durably reduce pain and improve mobility, with little risk of complications. This article aims to provide a narrative literature review of sacroplasty including, patient selection and optimization, the various technical approaches, and short and long-term outcomes.

Variability in expenses related to spine oncology care: comparison of payer-negotiated rates at National Cancer Institute-Designated Cancer Centers.

BACKGROUND: As of 2021, the Centers for Medicare and Medicaid Services (CMS) requires all hospitals to publish their commercially negotiated prices. To our knowledge, price variation of spine oncology diagnosis and treatments has not been previously investigated. PURPOSE: The aim of this study is to characterize the availability and variation of prices for spinal oncology services among National Cancer Institute-Designated Cancer Centers (NCI-DCC). STUDY DESIGN: Cross-sectional analysis. METHODS: Cancer centers were identified; those that did not provide patient care or participate in Medicare's Inpatient Prospective System were excluded. A cross-sectional analysis was conducted to gather commercially negotiated prices by searching online for "[center name] price transparency OR machine-readable file OR chargemaster." Data obtained was queried using 44 current procedural terminology (CPT) codes for imaging, procedures, and surgeries relevant to spine oncology. Comparison of prices was achieved by normalizing the median price for each service at each center to the estimated 2022 Medicare reimbursement for the center's Medicare Administrator Contractor. The ratios between the lowest and highest median commercial negotiated price within a center and across all centers were defined as "within-center ratio" and "across-center ratio" respectively. RESULTS: In total, 49 centers disclosed commercial payer-negotiated rates. Mean rate (±SD) for cervical corpectomy was $9,134 (±$10,034), thoracic laminectomy for neoplasm excision was $5,382 (±$5502), superficial bone biopsy was $1,853 (±$1,717), and single-photon emission computerized tomography (SPECT) was $813 (±$232). Within-center ratios ranged from 5.0 (SPECT scan) to 17.8 (radiofrequency bone ablation). Across-center ratios (for codes with > 10 centers reporting) ranged from 9.0 (corpectomy, thoracic, lateral extra-cavitary) to 418.7 (anterior approach cervical corpectomy). CONCLUSIONS: Price transparency for spinal oncology remains elusive despite recent CMS regulatory oversight, with marked heterogeneity in the quality of published rates complicating patients' ability to "shop" for care. Additionally, there continues to be significant variation in commercial rates for spine oncology diagnosis and treatment. CLINICAL SIGNIFICANCE: Despite regulation by CMS, prices for spinal oncology services are not uniformly available to patients and vary between NCI-DCC. The findings of this manuscript present potential barriers for patients to compare and obtain affordable care.

Assessing the Accuracy and Reliability of AI-Generated Responses to Patient Questions Regarding Spine Surgery.

BACKGROUND: In today's digital age, patients increasingly rely on online search engines for medical information. The integration of large language models such as GPT-4 into search engines such as Bing raises concerns over the potential transmission of misinformation when patients search for information online regarding spine surgery. METHODS: SearchResponse.io, a database that archives People Also Ask (PAA) data from Google, was utilized to determine the most popular patient questions regarding 4 specific spine surgery topics: anterior cervical discectomy and fusion, lumbar fusion, laminectomy, and spinal deformity. Bing's responses to these questions, along with the cited sources, were recorded for analysis. Two fellowship-trained spine surgeons assessed the accuracy of the answers on a 6-point scale and the completeness of the answers on a 3-point scale. Inaccurate answers were re-queried 2 weeks later. Cited sources were categorized and evaluated against Journal of the American Medical Association (JAMA) benchmark criteria. Interrater reliability was measured with use of the kappa statistic. A linear regression analysis was utilized to explore the relationship between answer accuracy and the type of source, number of sources, and mean JAMA benchmark score. RESULTS: Bing's responses to 71 PAA questions were analyzed. The average completeness score was 2.03 (standard deviation [SD], 0.36), and the average accuracy score was 4.49 (SD, 1.10). Among the question topics, spinal deformity had the lowest mean completeness score. Re-querying the questions that initially had answers with low accuracy scores resulted in responses with improved accuracy. Among the cited sources, commercial sources were the most prevalent. The JAMA benchmark score across all sources averaged 2.63. Government sources had the highest mean benchmark score (3.30), whereas social media had the lowest (1.75). CONCLUSIONS: Bing's answers were generally accurate and adequately complete, with incorrect responses rectified upon re-querying. The plurality of information was sourced from commercial websites. The type of source, number of sources, and mean JAMA benchmark score were not significantly correlated with answer accuracy. These findings underscore the importance of ongoing evaluation and improvement of large language models to ensure reliable and informative results for patients seeking information regarding spine surgery online amid the integration of these models in the search experience.

Management of traumatic spinal cord injury: A current concepts review of contemporary and future treatment.

Spinal Cord Injury (SCI) is a condition leading to inflammation, edema, and dysfunction of the spinal cord, most commonly due to trauma, tumor, infection, or vascular disturbance. Symptoms include sensory and motor loss starting at the level of injury; the extent of damage depends on injury severity as detailed in the ASIA score. In the acute setting, maintaining mean arterial pressure (MAP) higher than 85 mmHg for up to 7 days following injury is preferred; although caution must be exercised when using vasopressors such as phenylephrine due to serious side effects such as pulmonary edema and death. Decompression surgery (DS) may theoretically relieve edema and reduce intraspinal pressure, although timing of surgery remains a matter of debate. Methylprednisolone (MP) is currently used due to its ability to reduce inflammation but more recent studies question its clinical benefits, especially with inconsistency in recommending it nationally and internationally. The choice of MP is further complicated by conflicting evidence for optimal timing to initiate treatment, and by the reported observation that higher doses are correlated with increased risk of complications. Thyrotropin-releasing hormone may be beneficial in less severe injuries. Finally, this review discusses many options currently being researched and have shown promising pre-clinical results.

Cutibacterium acnes in spine surgery: pathophysiology, diagnosis, and treatment.

Cutibacterium acnes (C. acnes) previously named Propionibacterium acnes (P. acnes) has been increasingly recognized by spine surgeons as a cause of indolent postsurgical spinal infection. Patients infected with C. acnes may present with pseudarthrosis or nonspecific back pain. Currently, microbiological tissue cultures remain the gold standard in diagnosing C. acnes infection. Ongoing research into using genetic sequencing as a diagnostic method shows promising results and may be another future way of diagnosis. Optimized prophylaxis involves the use of targeted antibiotics, longer duration of antibiotic prophylaxis, antibacterial-coated spinal implants, and evidence-based sterile surgical techniques all of which decrease contamination. Antibiotics and implant replacement remain the mainstay of treatment, with longer durations of antibiotics proving to be more efficacious. Local guidelines must consider the surge of antimicrobial resistance worldwide when treating C. acnes.

Adolescent idiopathic scoliosis in adulthood.

Adolescent idiopathic scoliosis (AIS) is an abnormal coronal curvature of the spine that most commonly presents in adolescence. While it may be asymptomatic, AIS can cause pain, cosmetic deformity, and physical and psychological disability with curve progression. As adolescents with AIS enter adulthood, condition outcomes vary with some experiencing curve stabilization and others noting further curve progression, chronic pain, osteoporosis/fractures, declines in pulmonary and functional capacity, among others. Regular monitoring and individualized management by healthcare professionals are crucial to address the diverse challenges and provide appropriate support for a fulfilling adult life with AIS. This review examines the prevalence, risk factors, presenting symptoms, diagnosis, management, and complications of AIS in the adult population, informing targeted interventions by clinicians caring for adult patients with AIS.
