The Rare Large Common Peroneal Nerve's Schwannoma-A Case Report and Literature Review

Schwannoma in the popliteal fossa is still rare, often diagnosed late because it grows slowly and has no symptoms. It is often misdiagnosed with connective tissue tumors or with neurological disorders originating in the spine or disorders of the peroneal nerve. Schwannoma within the common peroneal nerve is still rare in the popliteal fossa, with most tumor sizes around 2 cm in diameter due to their smaller size of nerve but can cause neurologic disturbance, especially when it is large. And over a long time, it can cause serious complaints like neurological deficits and make surgery difficult by leaving greater sequelae. There is no data yet showing the incidence of schwannoma in the common peroneal nerve. In this case, a 36-year-old woman, for 5 years, feels soreness in the popliteal fossa and pain in the right instep, suspected that a nerve was pinched, due to an abnormality in the spine. As time went on, there was a lump in the fold of the right knee, suspected to be a Baker's cyst. As time went by, the complaint was burning pain in the right instep to the lateral ankle and distal right lower leg, disturbing sleep. Tinel's sign was positive. The right instep has hypoesthesia and a slight drop in the foot. On radiological examination of the right knee, a circumferential mass appeared, measuring 5 cm × 4 cm. The diagnosis is suspicious for a common peroneal nerve tumor. The encapsulated operation to remove the tumor was carried out with a size measuring 5 cm × 4.5 cm × 4 cm. The histopathological examination showed schwannoma. After surgery, the pain disappeared, hypoesthesia and a slight drop in the foot underwent physiotherapy, and stimulation with the result gradually improved. A thorough early examination includes correct and systematic anamnesis, physical examination, and neurological evaluation such as paraesthesia, hypoesthesia, and Tinel's sign; also, additional examinations, such as radiographic, ultrasound, and MRI, are needed for early detection of schwannoma so that delays in diagnosis and surgery can be avoided to prevent neurological deficits.

Risk and sex-specific trends of dementia and stroke in Italy Compared to European and high-income countries and the world: global implications

BACKGROUND

Understanding the increasing trends in Italy may inform new prevention strategies and better treatments. We investigated trends and risk factors of dementia, stroke, and ischemic heart disease (IHD) in Italy with the second-oldest population globally, compared to European and high-income countries and the world.

METHODS

We analyzed the Global Burden of Disease Study (GBD) 2019 estimates on incidence and burden (i.e., disability and death combined) of the three conditions in both sexes. We also analyzed the burden attributable to 12 modifiable risk factors and their changes during 1990-2019.

RESULTS

In 2019, Italy had 186,108 new dementias (123,885 women) and 94,074 new strokes (53,572 women). Women had 98% higher crude dementia and 24% higher crude stroke burdens than men. The average age-standardized new dementia rate was 114.7 per 100,000 women and 88.4 per 100,000 men, both higher than Western Europe, the European Union, high-income countries, and the world. During 1990-2019, this rate increased in both sexes (4%), despite a decline in stroke (- 45%) and IHD (- 17%) in Italy. Dementia burden attributable to tobacco decreased in both sexes (- 12.7%) during 1990-2019, while high blood glucose and high body mass index combined burden increased (25.4%). Stroke and IHD had similar trends.

CONCLUSIONS

While decreases in new strokes and IHDs are encouraging, new approaches to their joint prevention are required to reverse the rising dementia trends, especially among women. Life course approaches to promoting holistic brain health should be implemented at the community, national, and international levels before the growing trends become overwhelming.

The added value of frailty assessment as the premorbid stroke status on activities of daily living in patients with acute stroke, stratified by stroke severity

BACKGROUND

The modified Rankin scale (mRS) is extensively used for premorbid evaluation in patients with stroke; however, its limited capacity to assess functional status highlights the need for additional indicators such as frailty.

AIMS

This study aimed to assess the impact of the premorbid mRS score and frailty on daily living (ADL) activities at hospital discharge, focusing on varying stroke severities.

METHODS

This single-centre, prospective cohort study included patients with acute stroke aged ≥60 years. Key metrics included the frailty index for frailty assessment or mRS for functional status premorbid and the functional independence measure of the motor domain (FIM-M) at discharge for ADL outcomes. The patients were categorized into mild (0-4), moderate (5-15), and severe (16-42) groups based on the National Institute of Health Stroke Scale. Multiple hierarchical linear regression analyses were performed for each group to evaluate the influence of mRS and frailty on FIM-M scores.

RESULTS

In the mild stroke group, significant associations were observed with premorbid mRS3 (β = -0.183, p = 0.004), mRS4 (β = -0.234, p < 0.001), and frailty status (β = -0.227, p = 0.005) and FIM-M scores. Premorbid frailty did not show a significant association with the FIM-M scores in the moderate or severe stroke group. Frailty status notably contributed to changes in R², particularly in the mild stroke group (R² change = 0.031, p = 0.002). However, such changes were not evident in the other stroke severity groups.

CONCLUSION

This study emphasizes the importance of incorporating frailty assessments into premorbid evaluations, particularly when considering ADL outcomes in patients with mild stroke. Conversely, the significance of frailty in moderate-to-severe stroke was less evident.

Artificial intelligence in neurology: opportunities, challenges, and policy implications

Neurological conditions are the leading cause of disability and mortality combined, demanding innovative, scalable, and sustainable solutions. Brain health has become a global priority with adoption of the World Health Organization's Intersectoral Global Action Plan in 2022. Simultaneously, rapid advancements in artificial intelligence (AI) are revolutionizing neurological research and practice. This scoping review of 66 original articles explores the value of AI in neurology and brain health, systematizing the landscape for emergent clinical opportunities and future trends across the care trajectory: prevention, risk stratification, early detection, diagnosis, management, and rehabilitation. AI's potential to advance personalized precision neurology and global brain health directives hinges on resolving core challenges across four pillars-models, data, feasibility/equity, and regulation/innovation-through concerted pursuit of targeted recommendations. Paramount actions include swift, ethical, equity-focused integration of novel technologies into clinical workflows, mitigating data-related issues, counteracting digital inequity gaps, and establishing robust governance frameworks balancing safety and innovation.

Compare the GCS and the Rotterdam CT Score in Predicting the Mortality and Disability of Patients with Traumatic Brain Injury

Background

Given the dearth of extensive research comparing the Glasgow Coma Scale with the Rotterdam scoring system for predicting mortality in trauma patients, this study was conducted to determine which scale provides a more realistic prediction of mortality in trauma patients after three months.

Materials and Methods

This observational study was performed at Kashani Hospital in Isfahan, Iran. Patients with TBI who were admitted between February 2022 and February 2023 were included in the study. Approval from the Ethical Committee of Isfahan University of Medical Sciences was obtained prior to conducting this study.

Results

We included 152 adult patients who completed the GOS-E and the QOLIBRI-OS three-month post-injury. The median age was 35 years (IQR = 17-70). Most patients 139 (91.4%) were classified as having a severe TBI.

Conclusion

The results of the present study showed that both the use of GCS and Rotterdam CT scores can be effective in predicting the three-month mortality and QOLIBRI-OS scores of patients, with the difference that the predictive power of the three-month Rotterdam CT score is greater than that of the GCS.

Association between the blood urea nitrogen-to-creatinine ratio and 3-month outcomes in patients with acute ischemic stroke: a secondary analysis based on a prospective cohort study

Introduction

This study aimed to assess the correlation between the blood urea nitrogen (BUN)-to-creatinine (BUN/Cr) ratio and adverse outcomes (AOs) at 3 months in patients with acute ischemic stroke (AIS) in the Korean population.

Methods

This cohort study encompassed 1906 cases of AIS at a South Korean hospital from January 2010 to December 2016. To determine the linear correlation between the BUN/Cr ratio and AOs in AIS, a binary logistic regression model (BLRM) was employed. Additionally, generalized additive models and techniques for smooth curve fitting were utilized to reveal the nonlinear dynamics between the BUN/Cr ratio and AOs in patients with AIS.

Results

The prevalence of AOs was 28.65%, with a median BUN/Cr ratio of 18.96. Following adjustments for covariates, the BLRM disclosed that the association between the BUN/Cr ratio and the risk of AOs in patients with AIS did not attain statistical significance. Nevertheless, a nonlinear relationship surfaced, pinpointing an inflection point at 21.591. To the left of this inflection point, a 31.42% reduction in the risk of AOs was noted for every 1-unit surge in the Z score of the BUN/Cr ratio [odds ratio (OR) = 0.686, 95% confidence interval (CI): 0.519, 0.906, p = 0.008]. On the right side of the inflection point, the effect size (OR = 1.405, 95% CI: 1.018, 1.902, p = 0.039) was determined.

Conclusion

The findings of this study underscore the intricate nature of the relationship between the BUN/Cr ratio and 3-month outcomes in patients with AIS, establishing a robust groundwork for future investigations.

Length of Hospitalization and Mortality among Stroke Patients before and after the Implementation of a Specialized Unit: A Retrospective Cohort Study Using Real-World Data from One Reference Hospital in Southern Brazil

Stroke constitutes a significant global cause of mortality and disability. The implementation of stroke units influences hospital quality indicators, guiding care management. We aimed to compare hospital length of stay (LOS), in-hospital mortality, and post-discharge mortality between stroke patients admitted in the pre- and post-implementation periods of a stroke unit in a public hospital in southern Brazil. This retrospective cohort study used real-world data from one reference hospital, focusing on the intervention (stroke unit) and comparing it to the general ward (control). We analyzed the electronic medical records of 674 patients admitted from 2009 to 2012 in the general ward and 766 patients from 2013 to 2018 in the stroke unit. Admission to the stroke unit was associated with a 43% reduction in the likelihood of prolonged hospitalization. However, there was no significant difference in the risk of in-hospital mortality between the groups (Hazard ratio = 0.90; Interquartile range = 0.58 to 1.39). The incidence of death at three, six and twelve months post-discharge did not differ between the groups. Our study results indicate significant improvements in care processes for SU patients, including shorter LOS and better adherence to treatment protocols. However, our observations revealed no significant difference in mortality rates, either during hospitalization or after discharge, between the SU and GW groups. While SU implementation enhances efficiency in stroke care, further research is needed to explore long-term outcomes and optimize management strategies.

Associations between Life's Essential 8 and post-stroke depression and all-cause mortality among US adults

BACKGROUND

Depression is the common mental disease after stroke. Our objective was to investigate the correlation of Life's Essential 8 (LE8), the recently updated evaluation of cardiovascular health, with the occurrence of post-stroke depression (PSD) and all-cause mortality among United States (US) adults.

METHODS

Participants with stroke were chosen from the National Health and Nutrition Examination Survey (NHANES) between 2005 and 2018. The relationship between LE8 and the risk of PSD was assessed through weighted multiple logistic models. A restricted cubic spline was employed for the examination of correlations. To demonstrate the stability of the results, sensitivity analysis and subgroup analysis were carried out. Furthermore, Cox regression models were used for the correlation between LE8 and all-cause mortality.

RESULTS

In this study, a total of 1071 participants were included for analysis. It was observed that LE8 score and PSD risk shared an inverse relationship in per 10 points increase [OR = 0.62 (0.52-0.74, P < 0.001)] in logistic regression models. The analysis of restricted cubic spline demonstrated approximately a noticeable inverse linear association between LE8 score and PSD risk. Sensitivity analysis verified the stability of the findings. Moreover, no statistically significant interactions were identified in subgroup analysis. A reverse association between LE8 score and all-cause mortality was also observed with a 10-point increase [HR = 0.85 (0.78-0.94, P < 0.001)] in cox regression models.

CONCLUSIONS

A negative correlation was discovered between LE8 score and PSD and all-cause mortality risk among US adults. We need to conduct large-scale prospective studies to further validate our results.

Skill Transfer from Laparoscopic Partial Nephrectomy to the Hugo™ RAS System: A Novel Proficiency Score to Assess Surgical Quality during the Learning Curve

Background/Objectives: The absence of validated tools to assess the skill transfer from laparoscopy to robotic surgery remains an unsolved issue in the context of robot-assisted partial nephrectomy (RAPN). We aimed to describe and validate a novel proficiency score to critically evaluate the surgical quality of RAPN with the Hugo™ RAS System (Medtronic, Minneapolis, MN, USA). Methods: Between October 2022 and September 2023, 27 consecutive patients underwent off-clamp RAPN for localized renal tumors at our institution. To analyze the learning curve (LC), the cohort was chronologically divided into two phases of 6 months each. Proficiency was defined as the achievement of trifecta while maintaining a comparable intraoperative time in the interquartile range of laparoscopic partial nephrectomy performed by the same surgeon. A logistic binary regression model was built to identify predictors of proficiency achievement. Results: A proficiency score was achieved in 14 patients (74.1%). At univariable analysis, number of consecutive procedures > 12 (OR 13.7; 95%CI 2.05-21.1, p = 0.007), pathological tumor size (OR 0.92; 95%CI 0.89-0.99, p = 0.04) and essential blood hypertension (OR 0.16; 95%CI 0.03-0.82, p = 0.02) were found to be predictors of proficiency score. At multivariable analysis, after adjusting for potential confounding factors, number of consecutive procedures > 12 (OR 8.1; 95%CI 1.44-14.6, p = 0.03) was the only independent predictor of proficiency score achievement. Conclusions: Our results showed that the skills of an experienced laparoscopic surgeon are transferrable to the novel Hugo™ RAS System in the context of nephron-sparing surgery. Improved surgical quality may be expected after completing the first 12 consecutive procedures.

Hemorrhagic cerebral venous infarction after vein injury during intraoperative lesion resection: incidence, hemorrhagic stages, risk factors and prognosis

Objective

Cerebral venous infarction (CVI) after vein injury during intraoperative lesion resection is associated with intracranial hemorrhage. We conducted this study to identify the incidence, clinical and imaging features, and prognosis of hemorrhage CVI.

Methods

We performed a retrospective analysis of patients with confirmed CVI after vein injury who underwent craniotomy in our hospital. Postoperative clinical symptoms were observed, and imaging features were compared between patients with and without intracranial hemorrhages through CT examination. Variables were analyzed using univariate and multivariate regression analyses.

Results

Among 2,767 patients who underwent craniotomy, 93 cases of injured veins were identified intraoperatively. Hemorrhagic CVI was found in 38% (35/93). Multivariate analysis revealed that midline approach, meningioma, postoperative seizures, disorders of consciousness and interval in hours < 72 h were identified as predictors of hemorrhagic CVI. After 3 months of follow-up, the prognosis was poor in 15 cases (16%, 15/93), including death (two cases), vegetative survival (four cases), and severe disability (nine cases).

Conclusions

Hemorrhagic CVI, as a critical complication after venous injury, can have disastrous consequences. Do not injure known veins intraoperatively. In case of injury, requisite remedial measures should be adopted during and after surgery.

Addressing Disparities in Acute Stroke Management and Prognosis

There are now abundant data demonstrating disparities in acute stroke management and prognosis; however, interventions to reduce these disparities remain limited. This special report aims to provide a critical review of the current landscape of disparities in acute stroke care and highlight opportunities to use implementation science to reduce disparities throughout the early care continuum. In the prehospital setting, stroke symptom recognition campaigns that have been successful in reducing prehospital delays used a multilevel approach to education, including mass media, culturally tailored community education, and professional education. The mobile stroke unit is an organizational intervention that has the potential to provide more equitable access to timely thrombolysis and thrombectomy treatments. In the hospital setting, interventions to address implicit biases among health care providers in acute stroke care decision-making are urgently needed as part of a multifaceted approach to advance stroke equity. Implementing stroke systems of care interventions, such as evidence-based stroke care protocols at designated stroke centers, can have a broader public health impact and may help reduce geographic, racial, and ethnic disparities in stroke care, although further research is needed. The long-term impact of disparities in acute stroke care cannot be underestimated. The consistent trend of longer time to treatment for Black and Hispanic people experiencing stroke has direct implications on long-term disability and independence after stroke. A learning health system model may help expedite the translation of evidence-based interventions into clinical practice to reduce disparities in stroke care.

Addressing disparities in the global epidemiology of stroke

Stroke is the second leading cause of death and the third leading cause of disability worldwide. Though the burden of stroke worldwide seems to have declined in the past three decades, much of this effect reflects decreases in high-income countries (HICs). By contrast, the burden of stroke has grown rapidly in low-income and middle-income countries (LMICs), where epidemiological, socioeconomic and demographic shifts have increased the incidence of stroke and other non-communicable diseases. Furthermore, even in HICs, disparities in stroke epidemiology exist along racial, ethnic, socioeconomic and geographical lines. In this Review, we highlight the under-acknowledged disparities in the burden of stroke. We emphasize the shifting global landscape of stroke risk factors, critical gaps in stroke service delivery, and the need for a more granular analysis of the burden of stroke within and between LMICs and HICs to guide context-appropriate capacity-building. Finally, we review strategies for addressing key inequalities in stroke epidemiology, including improvements in epidemiological surveillance and context-specific research efforts in under-resourced regions, development of the global workforce of stroke care providers, expansion of access to preventive and treatment services through mobile and telehealth platforms, and scaling up of evidence-based strategies and policies that target local, national, regional and global stroke disparities.

A narrative on diversity, equity, and inclusion in surgery: insights from the European Society of Coloproctology and identification of points for action

The focus of the 2022 European Society of Coloproctology (ESCP) annual campaign was diversity, equity, and inclusion (DEI) in surgery. The ESCP "Operation Equal Access" campaign sought to interview key-opinion leaders and trainees, to raise awareness on inequalities, inform the community of the status of the topic, and to identify future areas for improvement. The ESCP Social Media Working Group interviewed experts who have made significant contributions to DEI in colorectal surgery and were acknowledged opinion leaders in the field. The interviews focused on their career, professional life, experiences, and opportunities during their training, and their views on DEI in colorectal surgery. DEI principles, education, and values need further promotion to reduce and address bias within the profession and overall improve the experience of minority community including health professionals and patients. International Societies are working to facilitate training opportunities and overcome DEI, and networking have contributed to that. Collaborations between societies will be pivotal to contribute to offering research and leadership opportunities equally. Access to advanced workshops including cadaveric training and simulation can be consistently promoted and provided globally via societies through telemonitoring. Involving patients in research should be encouraged, as it brings the perspective of a living experience.

Developing Systems of Care for Stroke in Resource-limited Settings

Although stroke prevention and treatment strategies have significantly advanced in recent years, implementation of these care elements in resource-limited settings can be challenging, since the burden of stroke is higher and access to stroke care is lower. Barriers to stroke care in resource-limited settings include insufficient prevention, reduced awareness of stroke symptoms, limited prehospital care and lack of triage systems, limited access to comprehensive stroke centers, inadequate personnel education, lack of staff and resources, as well as limited access to neuroimaging, thrombolytics, mechanical thrombectomy, neurosurgical care, and rehabilitation. Here, we suggest strategies to improve stroke care in these settings, including public health campaigns, protocols for prehospital notification, organized flow to specialized stroke centers, development of dedicated stroke units, and utilization of telemedicine and telerehabilitation. We also highlight the role of international organizations and governments in reducing the global burden of stroke.

National plans and awareness campaigns as priorities for achieving global brain health

Neurological conditions are the leading cause of death and disability combined. This public health crisis has become a global priority with the introduction of WHO's Intersectoral Global Action Plan on Epilepsy and Other Neurological Disorders 2022-2031 (IGAP). 18 months after this plan was adopted, global neurology stakeholders, including representatives of the OneNeurology Partnership (a consortium uniting global neurology organisations), take stock and advocate for urgent acceleration of IGAP implementation. Drawing on lessons from relevant global health contexts, this Health Policy identifies two priority IGAP targets to expedite national delivery of the entire 10-year plan: namely, to update national policies and plans, and to create awareness campaigns and advocacy programmes for neurological conditions and brain health. To ensure rapid attainment of the identified priority targets, six strategic drivers are proposed: universal community awareness, integrated neurology approaches, intersectoral governance, regionally coordinated IGAP domestication, lived experience-informed policy making, and neurological mainstreaming (advocating to embed brain health into broader policy agendas). Contextualised with globally emerging IGAP-directed efforts and key considerations for intersectoral policy design, this novel framework provides actionable recommendations for policy makers and IGAP implementation partners. Timely, synergistic pursuit of the six drivers might aid WHO member states in cultivating public awareness and policy structures required for successful intersectoral roll-out of IGAP by 2031, paving the way towards brain health for all.

The Operating Room management for emergency Surgical Activity (ORSA) study: a WSES international survey

BACKGROUND

Despite advances and improvements in the management of surgical patients, emergency and trauma surgery is associated with high morbidity and mortality. This may be due in part to delays in definitive surgical management in the operating room (OR). There is a lack of studies focused on OR prioritization and resource allocation in emergency surgery. The Operating Room management for emergency Surgical Activity (ORSA) study was conceived to assess the management of operating theatres and resources from a global perspective among expert international acute care surgeons.

METHOD

The ORSA study was conceived as an international web survey. The questionnaire was composed of 23 multiple-choice and open questions. Data were collected over 3 months. Participation in the survey was voluntary and anonymous.

RESULTS

One hundred forty-seven emergency and acute care surgeons answered the questionnaire; the response rate was 58.8%. The majority of the participants come from Europe. One hundred nineteen surgeons (81%; 119/147) declared to have at least one emergency OR in their hospital; for the other 20/147 surgeons (13.6%), there is not a dedicated emergency operating room. Forty-six (68/147)% of the surgeons use the elective OR to perform emergency procedures during the day. The planning of an emergency surgical procedure is done by phone by 70% (104/147) of the surgeons.

CONCLUSIONS

There is no dedicated emergency OR in the majority of hospitals internationally. Elective surgical procedures are usually postponed or even cancelled to perform emergency surgery. It is a priority to validate an effective universal triaging and scheduling system to allocate emergency surgical procedures. The new Timing in Acute Care Surgery (TACS) was recently proposed and validated by a Delphi consensus as a clear and reproducible triage tool to timely perform an emergency surgical procedure according to the clinical severity of the surgical disease. The new TACS needs to be prospectively validated in clinical practice. Logistics have to be assessed using a multi-disciplinary approach to improve patients' safety, optimise the use of resources, and decrease costs.

Identifying clusters of objective functional impairment in patients with degenerative lumbar spinal disease using unsupervised learning

OBJECTIVES

The five-repetition sit-to-stand (5R-STS) test was designed to capture objective functional impairment (OFI), and thus provides an adjunctive dimension in patient assessment. It is conceivable that there are different subsets of patients with OFI and degenerative lumbar disease. We aim to identify clusters of objectively functionally impaired individuals based on 5R-STS and unsupervised machine learning (ML).

METHODS

Data from two prospective cohort studies on patients with surgery for degenerative lumbar disease and 5R-STS times of ≥ 10.5 s-indicating presence of OFI. K-means clustering-an unsupervised ML algorithm-was applied to identify clusters of OFI. Cluster hallmarks were then identified using descriptive and inferential statistical analyses.

RESULTS

We included 173 patients (mean age [standard deviation]: 46.7 [12.7] years, 45% male) and identified three types of OFI. OFI Type 1 (57 pts., 32.9%), Type 2 (81 pts., 46.8%), and Type 3 (35 pts., 20.2%) exhibited mean 5R-STS test times of 14.0 (3.2), 14.5 (3.3), and 27.1 (4.4) seconds, respectively. The grades of OFI according to the validated baseline severity stratification of the 5R-STS increased significantly with each OFI type, as did extreme anxiety and depression symptoms, issues with mobility and daily activities. Types 1 and 2 are characterized by mild to moderate OFI-with female gender, lower body mass index, and less smokers as Type I hallmarks.

CONCLUSIONS

Unsupervised learning techniques identified three distinct clusters of patients with OFI that may represent a more holistic clinical classification of patients with OFI than test-time stratifications alone, by accounting for individual patient characteristics.

Endovascular Thrombectomy for Acute Ischemic Stroke in Indonesia: Challenging and Strategic Planning

High rates of morbidity and mortality indicate that stroke is a major health concern. Unfortunately, the management of ischemic stroke is hindered by several obstacles, particularly in developing countries such as Indonesia, where the burden of morbidity and mortality remains high. In this literature review, we intend to conduct a thorough investigation and analysis of the obstacles to stroke thrombectomy in developing countries, with a focus on Indonesia. Even though numerous studies and recent advances in thrombectomy techniques have been developed, many centers around the world continue to struggle to implement them. The majority of these institutions are located in developing nations like Indonesia. It faces numerous obstacles, including a lack of public awareness, infrastructure, human resources, and financial difficulties. The absence of early education and large-scale campaigns contributes to the dearth of public awareness. Inadequate imaging facilities, prehospital and referral systems, as well as disparities in healthcare expenditure and accessibility, contribute to the absence of infrastructure. Inadequate numbers of neurointerventionists, neurologists, and neurosurgeons, as well as a disparate distribution of these professionals, contribute to human resource issues. Inadequate national insurance coverage, high import tariffs on medical devices, and the high cost of healthcare have a negative impact on the financial situation. We provide related strategies regarding the current situation in Indonesia based on the recent evidence and comparison with developed countries. Academic institutions, medical associations, and government agencies must collaborate to overcome these challenges.

Research on the multidimensional brain remodeling mechanisms at the level of brain regions, circuits, and networks in patients with chronic lower back pain caused by lumbar disk herniation

Introduction

Chronic lower back pain (cLBP), frequently attributed to lumbar disk herniation (LDH), imposes substantial limitations on daily activities. Despite its prevalence, the neural mechanisms underlying lower back pain remain incompletely elucidated. Functional magnetic resonance imaging (fMRI) emerges as a non-invasive modality extensively employed for investigating neuroplastic changes in neuroscience. In this study, task-based and resting-state fMRI methodologies are employed to probe the central mechanisms of lower back pain.

Methods

The study included 71 chronic lower back pain patients (cLBP group) due to LDH and 80 age, gender, and education-matched healthy volunteers (HC group). The subjects are mainly middle-aged and elderly individuals. Visual Analog Scale (VAS), Oswestry Disability Index (ODI), and Japanese Orthopedic Association Scores (JOA) were recorded. Resting-state and task-based fMRI data were collected.

Results/discussion

No significant differences were observed in age, gender, and education level between the two groups. In the cLBP group during task execution, there was diffuse and reduced activation observed in the primary motor cortex and supplementary motor area. Additionally, during resting states, notable changes were detected in brain regions, particularly in the frontal lobe, primary sensory area, primary motor cortex, precuneus, and caudate nucleus, accompanied by alterations in Amplitude of Low Frequency Fluctuation, Regional Homogeneity, Degree Centrality, and functional connectivity. These findings suggest that chronic lower back pain may entail reduced excitability in sensory-motor areas during tasks and heightened activity in the sensory-motor network during resting states, along with modified functional connectivity in various brain regions.

Severity-Driven Trends in Mortality in a Large Regionalized Critical Care Transport Service

OBJECTIVE

The epidemiology accompanying helicopter emergency medical services (HEMS) transport has evolved as agencies have matured and become integrated into regionalized health systems, as evidenced primarily by nationwide systems in Europe. System-level congruence between Europe and the United States, where HEMS is geographically fragmentary, is unclear. In this study, we provide a temporal, epidemiologic characterization of the largest standardized private, nonprofit HEMS system in the United States, STAT MedEvac.

METHODS

We obtained comprehensive timing, procedure, and vital signs data from STAT MedEvac prehospital electronic patient care records for all adult patients transported to UPMC Health System hospitals in the period of January 2012 through October 2021. We linked these data with hospital electronic health records available through June 2018 to establish length of stay and vital status at discharge.

RESULTS

We studied 90,960 transports and matched 62.8% (n = 57,128) to the electronic health record. The average patient age was 58.6 years ( 19 years), and most were male (57.9%). The majority of cases were interfacility transports (77.6%), and the most common general medical category was nontrauma (72.7%). Sixty-one percent of all patients received a prehospital intervention. Overall, hospital mortality was 15%, and the average hospital length of stay (LOS) was 8.8 days ( 10.0 days). Observed trends over time included increases in nontrauma transports, level of severity, and in-hospital mortality. In multivariable models, case severity and medical category correlated with the outcomes of mortality and LOS.

CONCLUSION

In the largest standardized nonprofit HEMS system in the United States, patient mortality and hospital LOS increased over time, whereas the proportion of trauma patients and scene runs decreased.

Bidirectional modification effects on nonlinear associations of summer temperature and air pollution with first-ever stroke morbidity

High temperature and air pollution may induce stroke morbidity. However, whether associations between high temperature and air pollution with stroke morbidity are modified by each other is still unclear. Data on 23,578 first-ever stroke patients in Shenzhen, China, during the summers of 2014-2018 were collected. Distributed lag nonlinear models were used to assess the modifying effects of air pollution stratified by the median for the associations between summer temperature and stroke morbidity at 0-3 lag days; modifying effects of temperature stratified by the minimum morbidity temperature on the associations between air pollution and stroke morbidity at the same lags were also estimated. The attributable risks of high temperature and high pollution on stroke morbidity were quantified. Stratified analyses of gender, age, migration type, and complication type were conducted to assess vulnerable population characteristics. Summer high temperature may induce stroke morbidity at high-level PM2.5, PM10, O3, SO2, and NO2 conditions, with attributable fraction (AF) of 2.982% (95% empirical confidence interval [eCI]: 0.943, 4.929), 3.113% (0.948, 5.200), 2.841% (0.943, 4.620), 3.617% (1.539, 5.470), and 2.048% (0.279, 3.637), respectively. High-temperature effects were statistically insignificant at corresponding low-level air pollution conditions. High-level PM2.5, PM10, and O3 may induce stroke morbidity at high-temperature conditions, with AF of 3.664% (0.036, 7.196), 4.129% (0.076, 7.963), and 4.574% (1.009, 7.762), respectively. High-level PM2.5, PM10, and O3 were not associated with stroke morbidity at low-temperature conditions. The effects of high temperature and high pollution on stroke morbidity were statistically significant among immigrants and patients with hypertension, dyslipidemia, or diabetes but insignificant among natives and patients without complications. The associations of summer temperature and air pollution with first-ever stroke morbidity may be enhanced bidirectionally. Publicity on the health risks of combined high temperature and high pollution events should be strengthened to raise protection awareness of relevant vulnerable populations.

Cancer screening in hospitalized ischemic stroke patients: a multicenter study focused on multiparametric analysis to improve management of occult cancers

Background/aims

The reciprocal promotion of cancer and stroke occurs due to changes in shared risk factors, such as metabolic pathways and molecular targets, creating a "vicious cycle." Cancer plays a direct or indirect role in the pathogenesis of ischemic stroke (IS), along with the reactive medical approach used in the treatment and clinical management of IS patients, resulting in clinical challenges associated with occult cancer in these patients. The lack of reliable and simple tools hinders the effectiveness of the predictive, preventive, and personalized medicine (PPPM/3PM) approach. Therefore, we conducted a multicenter study that focused on multiparametric analysis to facilitate early diagnosis of occult cancer and personalized treatment for stroke associated with cancer.

Methods

Admission routine clinical examination indicators of IS patients were retrospectively collated from the electronic medical records. The training dataset comprised 136 IS patients with concurrent cancer, matched at a 1:1 ratio with a control group. The risk of occult cancer in IS patients was assessed through logistic regression and five alternative machine-learning models. Subsequently, select the model with the highest predictive efficacy to create a nomogram, which is a quantitative tool for predicting diagnosis in clinical practice. Internal validation employed a ten-fold cross-validation, while external validation involved 239 IS patients from six centers. Validation encompassed receiver operating characteristic (ROC) curves, calibration curves, decision curve analysis (DCA), and comparison with models from prior research.

Results

The ultimate prediction model was based on logistic regression and incorporated the following variables: regions of ischemic lesions, multiple vascular territories, hypertension, D-dimer, fibrinogen (FIB), and hemoglobin (Hb). The area under the ROC curve (AUC) for the nomogram was 0.871 in the training dataset and 0.834 in the external test dataset. Both calibration curves and DCA underscored the nomogram's strong performance.

Conclusions

The nomogram enables early occult cancer diagnosis in hospitalized IS patients and helps to accurately identify the cause of IS, while the promotion of IS stratification makes personalized treatment feasible. The online nomogram based on routine clinical examination indicators of IS patients offered a cost-effective platform for secondary care in the framework of PPPM.

Twenty years on from the introduction of the high risk strategy for stroke and cardiovascular disease prevention: a systematic scoping review

BACKGROUND AND PURPOSE

Early this century, the high risk strategy of primary stroke and cardiovascular disease (CVD) prevention for individuals shifted away from identifying (and treating, as appropriate) all at-risk individuals towards identifying and treating individuals who exceed arbitrary thresholds of absolute CVD risk. The public health impact of this strategy is uncertain.

METHODS

In our systematic scoping review, the electronic databases (Scopus, MEDLINE, Embase, Google Scholar, Cochrane Library) were searched to identify and appraise publications related to primary CVD/stroke prevention strategies and their effectiveness published in any language from January 1990 to August 2023.

RESULTS

No published randomized controlled trial was found on the effectiveness of the high CVD risk strategy for primary stroke/CVD prevention. Targeting high CVD risk individuals excludes a large proportion of the population from effective blood-pressure-lowering and lipid-lowering treatment and effective CVD prevention. There is also evidence that blood pressure lowering and lipid lowering are beneficial irrespective of blood pressure and cholesterol levels and irrespective of absolute CVD risk and that risk-stratified pharmacological management of blood pressure and lipids to only high CVD risk individuals leads to significant underuse of blood-pressure-lowering and lipid-lowering medications in individuals otherwise eligible for such treatment.

CONCLUSIONS

Primary stroke and CVD prevention needs to be done in all individuals with increased risk of CVD/stroke. Pharmacological management of blood pressure and blood cholesterol should not be solely based on the high CVD risk treatment thresholds. International guidelines and global strategies for primary CVD/stroke prevention need to be revised.

Delayed surgical treatment of asymptomatic severe traumatic C7-T1 spondylolisthesis: a rare case report from Syria

Introduction

Spondylolisthesis is described as the displacement of one vertebra over another, leading to spinal instability and potential nerve compression. When this occurs in the cervicothoracic junction, it can result in unique clinical manifestations. High-grade spondylolisthesis caused by trauma in the cervicothoracic junction of the spine usually results in acute spinal cord injury and quadriparesis. However, a few uncommon cases of the same injury reported minimal or no neurological deficits. Biomechanical evaluation of the underlying pathology can offer insights into the mechanism of injury and the preservation of neurological function.

Case presentation

This paper explains the case of a 32-year-old white male patient who suffered from a traumatic C7-T1 spondylolisthesis. Despite having radiographic evidence of grade III traumatic spondylolisthesis, cord compression, fracture in the isthmus of the C7 vertebra, and intervertebral disc traumatic change and protrusion, the patient did not exhibit any motor neurological deficits. The patient underwent posterior spine fixation via the posterior approach as the first step of the surgical management, followed by anterior spine fixation via the anterior approach after several days (360° fixation). Fortunately, after 6 months of follow-up, the patient showed good outcomes. The patient was pain-free with an intact neurological clinical examination, the radiographs showed well-maintained fusion and alignment.

Discussion

The best management approach to cervical spondylolisthesis without neurological injury is complicated and arguable due to the rarity of occurrence of such cases.

Conclusion

A combined anteroposterior surgical approach, or 360° fixation, is a valuable technique for addressing complex spinal conditions such as the condition seen in our case, offering comprehensive stabilization and improved outcomes.

Achieving Surgical, Obstetric, Trauma, and Anesthesia (SOTA) care for all in South Asia

South Asia is a demographically crucial, economically aspiring, and socio-culturally diverse region in the world. The region contributes to a large burden of surgically-treatable disease conditions. A large number of people in South Asia cannot access safe and affordable surgical, obstetric, trauma, and anesthesia (SOTA) care when in need. Yet, attention to the region in Global Surgery and Global Health is limited. Here, we assess the status of SOTA care in South Asia. We summarize the evidence on SOTA care indicators and planning. Region-wide, as well as country-specific challenges are highlighted. We also discuss potential directions-initiatives and innovations-toward addressing these challenges. Local partnerships, sustained research and advocacy efforts, and politics can be aligned with evidence-based policymaking and health planning to achieve equitable SOTA care access in the South Asian region under the South Asian Association for Regional Cooperation (SAARC).

Venovenous extracorporeal membrane oxygenation in patients with traumatic brain injuries and severe respiratory failure: A single-center retrospective analysis

BACKGROUND

Venovenous extracorporeal membrane oxygenation (VV ECMO) can support trauma patients with severe respiratory failure. Use in traumatic brain injury (TBI) may raise concerns of worsening complications from intracranial bleeding. However, VV ECMO can rapidly correct hypoxemia and hypercarbia, possibly preventing secondary brain injury. We hypothesize that adult trauma patients with TBI on VV ECMO have comparable survival with trauma patients without TBI.

METHODS

A single-center, retrospective cohort study involving review of electronic medical records of trauma admissions between July 1, 2014, and August 30, 2022, with discharge diagnosis of TBI who were placed on VV ECMO during their hospital course was performed.

RESULTS

Seventy-five trauma patients were treated with VV ECMO; 36 (48%) had TBI. Of those with TBI, 19 (53%) had a hemorrhagic component. Survival was similar between patients with and without a TBI (72% vs. 64%, p = 0.45). Traumatic brain injury survivors had a higher admission Glasgow Coma Scale (7 vs. 3, p < 0.001) than nonsurvivors. Evaluation of prognostic scoring systems on initial head computed tomography demonstrated that TBI VV ECMO survivors were more likely to have a Rotterdam score of 2 (62% vs. 20%, p = 0.03) and no survivors had a Marshall score of ≥4. Twenty-nine patients (81%) had a repeat head computed tomography on VV ECMO with one incidence of expanding hematoma and one new focus of bleeding. Neither patient with a new/worsening bleed received anticoagulation. Survivors demonstrated favorable neurologic outcomes at discharge and outpatient follow-up, based on their mean Rancho Los Amigos Scale (6.5; SD, 1.2), median Cerebral Performance Category (2; interquartile range, 1-2), and median Glasgow Outcome Scale-Extended (7.5; interquartile range, 7-8).

CONCLUSION

In this series, the majority of TBI patients survived and had good neurologic outcomes despite a low admission Glasgow Coma Scale. Venovenous extracorporeal membrane oxygenation may minimize secondary brain injury and may be considered in select patients with TBI.

Traumatic Brain Injury Outcome Associations With Computed Tomography and Glasgow Coma Scale Score Interactions: A Retrospective Study

Background Numerous investigators have shown that early postinjury Glasgow Coma Scale (GCS) values are associated with later clinical outcomes in patients with traumatic brain injury (TBI), in-hospital mortality, and post-hospital discharge Glasgow Outcome Scale (GOS) results. Following TBI, early GCS, and brain computed tomography (CT) scores have been associated with clinical outcomes. However, only one previous study combined GCS scores with CT scan results and demonstrated an interaction with in-hospital mortality and GOS results. We aimed to determine if interactive GCS and CT findings would be associated with outcomes better than GCS and CT findings alone. Methodology Our study included TBI patients who had GCS scores of 3-12 and required mechanical ventilation for ≥five days. The GCS deficit was determined as 15 minus the GCS score. The mass effect CT score was calculated as lateral ventricular compression plus basal cistern compression plus midline shift. Each value was 1 for present. A prognostic CT score was the mass effect score plus subarachnoid hemorrhage (2 if present).The CT-GCS deficit score was the sum of the GCS deficit and the prognostic CT score. Results One hundred and twelve consecutive TBI patients met the inclusion criteria. Patients with surgical decompression had a lower GCS score (6.0±3.0) than those without (7.7±3.3; Cohen d=0.54). Patients with surgical decompression had a higher mass effect CT score (2.8±0.5) than those without (1.7±1.0; Cohen d=1.4). The GCS deficit was greater in patients not following commands at hospital discharge (9.6±2.6) than in those following commands (6.8±3.2; Cohen d=0.96). The prognostic CT score was greater in patients not following commands at hospital discharge (3.7±1.2) than in those following commands (3.1±1.1; Cohen d=0.52). The CT-GCS deficit score was greater in patients not following commands at hospital discharge (13.3±3.2) than in those following commands (9.9±3.2; Cohen d=1.06). Logistic regression stepwise analysis showed that the failure to follow commands at hospital discharge was associated with the CT-GCS deficit score but not with the GCS deficit. The GCS deficit was greater in patients not following commands at three months (9.7±2.8) than in those following commands (7.4±3.2; Cohen d=0.78). The CT-GCS deficit score was greater in patients not following commands at three months (13.6±3.1) than in those following commands (10.5±3.4; Cohen d=0.94). Logistic regression stepwise analysis showed that failure to follow commands at three months was associated with the CT-GCS deficit score but not with the GCS deficit. The proportion not following commands at three months was greater with a GCS deficit of 9-12 (50.9%) than with a GCS deficit of 3-8 (21.1%; odds ratio=3.9; risk ratio=2.1). The proportion of not following commands at three months was greater with a CT-GCS deficit score of 13-17 (56.0%) than with a CT-GCS deficit score of 4-12 (18.3%; OR=5.7; RR=3.1). Conclusion The mass effect CT score had a substantially better association with the need for surgical decompression than did the GCS score. The degree of association for not following commands at hospital discharge and three months was greater with the CT-GCS deficit score than with the GCS deficit. These observations support the notion that a mass effect and subarachnoid hemorrhage composite CT score can interact with the GCS score to better prognosticate TBI outcomes than the GCS score alone.

Building Bridges between People with Stroke, Families, and Health Professionals: Development of a Blended Care Program for Self-Management

Evidence-informed interventions for stroke self-management support can influence functional capability and social participation. People with stroke should be offered self-management support after hospital discharge. However, in Portugal, there are no known programs of this nature. This study aimed to develop a person-centered and tailored blended care program for post-stroke self-management, taking into account the existing evidence-informed interventions and the perspectives of Portuguese people with stroke, caregivers, and health professionals. An exploratory sequential mixed methods approach was used, including qualitative methods during stakeholder consultation (stage 1) and co-production (stage 2) and quantitative assessment during prototyping (stage 3). After ethical approval, recruitment occurred in three health units. Results from a literature search led to the adaptation of the Bridges Stroke Self-Management Program. In stage one, 47 participants were interviewed, with two themes emerging: (i) Personalized support and (ii) Building Bridges through small steps. In stage two, the ComVida program was developed, combining in-person and digital approaches, supported by a workbook and a mobile app. In stage three, 56 participants evaluated prototypes, demonstrating a strong level of quality. Understandability and actionability of the developed tools obtained high scores (91-100%). The app also showed good usability (A-grade) and high levels of recommendation (5 stars).

Evaluation of a quality improvement intervention to reduce anastomotic leak following right colectomy (EAGLE): pragmatic, batched stepped-wedge, cluster-randomized trial in 64 countries

BACKGROUND

Anastomotic leak affects 8 per cent of patients after right colectomy with a 10-fold increased risk of postoperative death. The EAGLE study aimed to develop and test whether an international, standardized quality improvement intervention could reduce anastomotic leaks.

METHODS

The internationally intended protocol, iteratively co-developed by a multistage Delphi process, comprised an online educational module introducing risk stratification, an intraoperative checklist, and harmonized surgical techniques. Clusters (hospital teams) were randomized to one of three arms with varied sequences of intervention/data collection by a derived stepped-wedge batch design (at least 18 hospital teams per batch). Patients were blinded to the study allocation. Low- and middle-income country enrolment was encouraged. The primary outcome (assessed by intention to treat) was anastomotic leak rate, and subgroup analyses by module completion (at least 80 per cent of surgeons, high engagement; less than 50 per cent, low engagement) were preplanned.

RESULTS

A total 355 hospital teams registered, with 332 from 64 countries (39.2 per cent low and middle income) included in the final analysis. The online modules were completed by half of the surgeons (2143 of 4411). The primary analysis included 3039 of the 3268 patients recruited (206 patients had no anastomosis and 23 were lost to follow-up), with anastomotic leaks arising before and after the intervention in 10.1 and 9.6 per cent respectively (adjusted OR 0.87, 95 per cent c.i. 0.59 to 1.30; P = 0.498). The proportion of surgeons completing the educational modules was an influence: the leak rate decreased from 12.2 per cent (61 of 500) before intervention to 5.1 per cent (24 of 473) after intervention in high-engagement centres (adjusted OR 0.36, 0.20 to 0.64; P < 0.001), but this was not observed in low-engagement hospitals (8.3 per cent (59 of 714) and 13.8 per cent (61 of 443) respectively; adjusted OR 2.09, 1.31 to 3.31).

CONCLUSION

Completion of globally available digital training by engaged teams can alter anastomotic leak rates. Registration number: NCT04270721 (http://www.clinicaltrials.gov).

Embracing virtual reality in rehabilitation of post-stroke aphasia

About one-third of stroke survivors experience aphasia, i.e., language dysfunction caused by brain damage. Aphasia affects not only a person's ability to communicate, but it often leads to the inability to return to work, loss of close relationships, diminished quality of life, negative self-perception, and depression. Yet persons with aphasia are globally underserved due to limited access to resources, which limits their chance for recovery. Immersive virtual reality (VR) has the potential to solve this problem and deliver efficient, personalized treatments to millions of people worldwide who need access to rehabilitation services or more flexibility in treatment delivery. To reduce the global burden of stroke experts recommend taking bold, pragmatic actions across all four pillars of stroke quadrangle-surveillance, prevention, acute care, and rehabilitation. Embracing immersive VR-based rehabilitation of poststroke aphasia would be one step in that direction.

Designing machine learning for big data: A study to identify factors that increase the risk of ischemic stroke and prognosis in hypertensive patients

Background

Ischemic stroke (IS) accounts large amount of stroke incidence. The aim of this study was to discover the risk and prognostic factors that affecting the occurrence of IS in hypertensive patients.

Method

Study data were obtained from the Medical Information Mart for Intensive Care (MIMIC)-IV database. To avoid biased factors selection process, several approaches were studied including logistic regression, elastic net regression, random forest, correlation analysis, and multifactor logistic regression methods. And seven different machine-learning methods are used to construct predictive models. The performance of the developed models was evaluated using AUC (Area Under the Curve), prediction accuracy, precision, recall, F1 score, PPV (Positive Predictive Value) and NPV (Negative Predictive Value). Interaction analysis was conducted to explore potential relationships between influential factors.

Results

The study included 92,514 hypertensive patients, of which 1746 hypertensive patients experienced IS. The Gradient Boosted Decision Tree (GBDT) model outperformed the other prediction model terms of prediction accuracy and AUC values in both ischemic and prognosis cases. By using the SHapley Additive exPlanations (SHAP), we found that a range of factors and corresponding interactions between factors are important risk factors for IS and its prognosis in hypertensive patients.

Conclusion

The study identified factors that increase the risk of IS and poor prognosis in hypertensive patients, which may provide guidance for clinical diagnosis and treatment.

Long-term therapy with dienogest or other oral cyclic estrogen-progestogen can reduce the need for ovarian endometrioma surgery

BACKGROUND

Almost 10% of women in reproductive age are diagnosed with ovarian endometriomas and can experience symptoms and infertility disorders. Ovarian endometriomas can be treated with medical or surgical therapy.

OBJECTIVE

To assess whether long-term therapy with dienogest or oral cyclic estrogen-progestogens is effective in reducing the size of ovarian endometriomas, alleviating associated symptoms, and reducing the requirement for surgery.

DESIGN

Prospective non-interventional cohort study.

METHODS

We enrolled childbearing women diagnosed with ovarian endometriomas. We collected demographic, clinical, and surgical data, including the evaluation of ovarian endometrioma-associated symptoms and pain using the visual analog scale. We grouped the women according to treatment regimen into dienogest, estrogen-progestogens, and no-treatment. Patient's assessment was performed at baseline and after 12 months evaluating the largest ovarian endometrioma diameter (in millimeters) and the associated symptoms. Furthermore, we analyzed the impact of hormonal treatment in a sub-group of women fulfilling at baseline the criteria for a first-line surgical approach (ovarian endometrioma > 30 mm with visual analog scale > 8 or ovarian endometrioma > 40 mm before assisted reproductive treatments or any ovarian endometrioma(s) > 60 mm).

RESULTS

We enrolled 142 patients: 62, 38, and 42 in dienogest, estrogen-progestogens, and no-treatment groups, respectively. No significant differences were found regarding baseline characteristics. After 12 months, the mean largest ovarian endometrioma diameter increased in the no-treatment group (31.1 versus 33.8; p < 0.01), while a significant reduction was registered in the dienogest (35.1 versus 25.8; p < 0.01) and estrogen-progestogens (28.4 versus 16.7; p < 0.01) groups; no significant difference in ovarian endometrioma diameter reduction between these two latter groups was noted (p = 0.18). Ovarian endometrioma-associated symptoms and pain improved in dienogest and estrogen-progestogens groups, with a significantly greater effect for dienogest than for estrogen-progestogens for dysmenorrhea (74% versus 59%; p < 0.01). In the sub-group of women eligible for first-line surgery at baseline, long-term treatment with dienogest and estrogen-progestogens reduced surgical eligibility by 30%.

CONCLUSIONS

Decreased mean largest ovarian endometriomas'diameter after 12 months and reduction of the need for surgical treatment by 30% were observed in dienogest and estrogen-progestogens groups. Long-term treatment with dienogest had a greater effect in alleviating dysmenorrhea and pain.

The management of low trans-sphincteric anal fistula during the COVID-19 pandemic: revisiting the role of the seton

The management of trans-sphincteric anal fistula (TAF) includes several surgical options; however, during the COVID-19 pandemic, the access to the operating rooms was severely limited, leaving only the choice of minimally invasive procedures. This study aimed to evaluate the safety and effectiveness of the slow cutting seton technique for TAF performed in an outpatient setting during the COVID-19 pandemic.Patients treated for TAF between January 2020 and July 2022 and followed-up for at least 12 months were retrospectively evaluated. A vascular silicone tie used as seton was positioned in the fistula tract using a Lockhart-Mummery fistula probe. The seton was maintained in moderate tension until the sphincter muscle was passed. Percentage and time for healing, recurrence, SF-36, VAS and Vaizey's Score were recorded.Fifty-eight patients [36 male/22 female, median age 56.5 years (IQR 41.25-65.75) [with TAF were included. After a median time of 4 months, complete healing occurred in 53 cases (91.5%), the anal pain VAS decreased from 6 to 0, the anal incontinence scores did not change significantly and the QoL improved significantly in all the SF36 domains. No complications were recorded, but the fistula recurred in five cases (8.5%). Two of them had additional seton treatment, and three underwent other surgical procedures after the COVID-19 emergency.The slow cutting seton technique is a safe and effective treatment for outpatient procedure with minimal patient discomfort. This treatment option in healthcare delivery for TAF should be reconsidered, even outside the limited in-hospital access during the COVID-19 pandemic.

Dry needling combined with exercise therapy: Effects on wrist flexors spasticity in post-stroke patients - A randomized controlled trial

BACKGROUND

The positive contribution of dry needling (DN) in conjunction with exercise therapy for patients with stroke and spasticity remains uncertain.

OBJECTIVE

To examine the effects of DN combined with exercise therapy on wrist flexor spasticity and motor function in patients with stroke.

METHODS

Twenty-four participants with stroke were randomly assigned to either the DN and exercise therapy group or the DN alone group. Assessments were conducted at baseline, after the 4th treatment session, and 3 weeks post-treatment.

RESULTS

A significant Group×Time interaction was observed for wrist active range of motion (ROM) (P = 0.046), favoring the DN with exercise therapy group (∼10° at baseline, ∼15° immediately after the 4th session, and 15.4° at follow-up). The improvements in spasticity, passive ROM, and H-reflex latency were sustained during follow-up. However, there were no significant between-group differences in any outcome at any measurement time point.

CONCLUSION

The combined DN and exercise therapy did not exhibit superiority over DN alone concerning spasticity severity and motor function. However, it demonstrated additional advantages, particularly in improving motor neuron excitability and wrist passive extension.

Invasive Preoperative Investigations in Idiopathic Normal Pressure Hydrocephalus: A Comprehensive Review

Idiopathic normal pressure hydrocephalus (iNPH) is a neurological disorder characterized by the triad of gait disturbance, cognitive impairment, and urinary incontinence. The condition is diagnosed mainly in older adults and is associated with ventricular enlargement without an increase in cerebrospinal fluid pressure. The clinical assessment involves a detailed medical history, physical examination, and cognitive testing. Neuroimaging is an essential part of the diagnostic workup for iNPH. However, to determine the suitability of patients for shunt surgery, a range of invasive preoperative investigations are employed. This narrative review aims to provide a comprehensive analysis of the current literature on invasive preoperative investigations in iNPH, focusing primarily on the lumbar infusion test, cerebrospinal fluid drainage tests, and continuous intracranial pressure monitoring. The strengths and limitations of each method, as well as their potential impact on treatment outcomes, are discussed.

Acute effect of shockwave therapy on plantar pressure distribution and balance in hemiparetic individuals

Abstract Introduction: Cerebral vascular accident (CVA) is the second leading cause of death and is one of the diseases that most generate disability Hemiparesis is the most common motor deficit, and one of its characteristics is asymmetry in weight bearing and in the plantar sup-port area, leading to balance deficits. extracorporeal shock-wave therapy (ESWT) has been shown to be effective in reducing post-stroke spasticity. Objective: To evaluate the effect of a ESWT session on the distribution of plantar pressure and on the static and dynamic balance of hemiparetic individuals after stroke. Methods: Twelve individuals with hemiparesis as a result of stroke in the chronic stage participated in the study. Data collection was divided into two days. On the first day, anamnesis and tests were performed: timed up and go (TUG), four square step test (FSST), and short physical performance battery (SPPB). After carrying out the tests, the distribution of plantar pressure was evaluated using baropodometry. Also on the first day, participants received ESWT in the muscle belly of the gastrocnemius muscle on the hemiparetic side. At the end of the ESWT session and after 7 days, the individuals were reassessed. Results: The results referring to the static and dynamic balance and baropodometry evaluations performed before, immediately after and one week after the application of ESWT did not show a significant difference between the three evaluations in any of the tests and in any of the moments performed. Conclusion: One ESWT session did not affect plantar pressure distribution and static and dynamic balance of hemiparetic individuals after stroke.

Universal Prevention of Dementia in Italy: A Document Analysis of the 21 Italian Regional Prevention Plans

BACKGROUND

Up to 40% of dementia cases are theoretically avoidable and population-level interventions (i.e., universal prevention) are a key component in facing the global public health challenge of dementia. However, information on the agenda for the universal prevention of dementia at the national and sub-national levels is still lacking.

OBJECTIVES

We aim to provide a comprehensive description of the universal prevention strategies specific to dementia in Italian regions and autonomous provinces (APs).

DESIGN

We conducted a document analysis of the 21 Italian Regional Prevention Plans (RPPs), with a focus on interventions that target potentially modifiable risk factors for dementia. We analysed the final version of the documents, which were previously downloaded from the dedicated section of the Italian Ministry of Health website in January 2023. We classified the interventions as direct, indirect, or absent. Additionally, we created a quality checklist to outline the essential programmatic elements and applied it to summarise the key findings of the RPPs.

MEASUREMENTS

We reported the number of population-level interventions specific for dementia with sub-national detail. We reported information on the risk factor targeted by the interventions, the age groups and populations they were designed for. We summarized the presence or absence of 63 programmatic items using a four-domain checklist.

RESULTS

We identified 248 interventions for dementia prevention among the assessed RPPs: 100% of the plans addressed physical inactivity; 30-35% addressed smoking, alcohol, obesity, and social isolation; 25% addressed hypertension, diabetes, and air pollution; only 5-10% addressed education, depression, and hearing loss. Most interventions targeted the general population. Quality checklist scores significantly varied among regions, with demographics and prevention strategies domains scoring higher than disease burden and intervention feasibility ones.

CONCLUSIONS

The population-level interventions in the Italian Regional Prevention Programs dedicated to dementia prevention primarily focus on vascular risk factors, with limited coverage of dementia-specific factors such as traumatic brain injury and hearing loss. This data should be considered when planning future interventions for dementia prevention.

[Features of primary and recurrent ischemic stroke in men aged 18-50 years]

OBJECTIVE

To evaluate the features of primary and recurrent stroke in men aged 18-50 years with atherothrombotic, lacunar, and cardioembolic subtypes.

MATERIAL AND METHODS

A total of 125 men with primary and recurrent stroke were included in the study. The main vascular risk factors and lifestyle-related risk factors were assessed. Neurological, neuroimaging, ultrasound and laboratory examinations were performed. Hemostasis parameters, lipid metabolism and endothelial function parameters were studied.

RESULTS

Among 125 men with ischemic stroke with a median age of 43 years, 104 (83.2%) patients had a primary stroke and 21 (16.8%) patients had a recurrent stroke. Recurrent stroke occurred more frequently in patients with the cardioembolic subtype (26.3%) and with almost equal frequency in patients with the atherothrombotic (13.3%) and lacunar (17.4%) subtypes. In the group as a whole, patients with primary and recurrent strokes did not differ in age (43.1±5.5 and 43.7±4.3 years, respectively). In a comparative analysis of patients with primary and recurrent stroke with different subtypes of stroke, significant differences in the main risk factors, indicators of lipid metabolism, hemostasis and endothelial function were obtained.

CONCLUSION

The study in men, aged 18-50 years, with atherothrombotic, lacunar and cardioembolic subtypes revealed the features of risk factors, indicators of hemostasis system, lipid metabolism and endothelial function in primary and recurrent stroke.
