Meta-Analysis Review
OBJECTIVE
Best medical therapy (BMT) should be recommended for treating uncomplicated Stanford type B aortic dissection (uSTBAD), whereas thoracic aortic endovascular repair (TEVAR) has been controversial for uSTBAD.
METHODS
In this paper, a meta-analysis was conducted on all available randomized controlled trials and observational studies that evaluated the relative benefits and harms of TEVAR and BMT for the management of patients suffering from uSTBAD. Primary endpoints consisted of early adverse events, long-term adverse events, and aortic remodeling. In addition, risk differences (RDs) or odds ratios (ORs) with 95% confidence intervals (CIs) were estimated. The random-effects model or the fixed-effects model was used in accordance with the 50% heterogeneity threshold.
RESULTS
Seven observational studies and two randomized controlled studies from 11 articles that contained 15,066 patients with uSTBAD (1518 TEVARs) met the inclusion criteria. For early outcomes, no significant differences were found between the TEVAR group and the BMT group in aortic rupture, retrograde dissection, paraplegia/paraparesis, reintervention, aorta-related death, and all-cause death. In the long run, the TEVAR group was found to have a significantly lower incidence of adverse events, which included aortic rupture (OR, 0.26; 95% CI, 0.16-0.42; P < .05; heterogeneity: P = .90, I = 0%), reintervention (OR, 0.45; 95% CI, 0.26-0.75; P < .05; heterogeneity: P = .17, I = 41%), aorta-related death (OR, 0.27; 95% CI, 0.18-0.42; P < .05; heterogeneity: P = .61, I = 0%), and all-cause death (OR, 0.52; 95% CI, 0.42-0.66; P < .05; heterogeneity: P = .05, I = 53%) as compared with the BMT group. Moreover, in compared with BMT, TEVAR was found to significantly contribute to the complete thrombosis of thoracic false lumen (OR, 55.34; 95% CI, 34.32-89.21; P < .05; heterogeneity: P = .97, I = 0%), and aortic regression (true lumen expansion and false lumen shrinkage).
CONCLUSIONS
Although early endovascular repair of uSTBAD does not outperform BMT, its implementation is found to be necessary to facilitate the long-term prognosis. Accordingly, if early TEVAR is to be deferred, close follow-up is critical to allow for timely reintervention.

Review
Nonpharmacological interventions and outcomes in the management of complications of human T-cell lymphotropic virus type 1-related myelopathy/tropical spastic paraparesis: A systematic review.
BACKGROUND
Human T-cell lymph tropic virus type 1 (HTLV-I)-related myelopathy/tropical spastic paraparesis (TSP) is a progressive inflammatory process affecting the spinal cord that occurs as a result of HTLV 1. The use of nonpharmacological approaches has always been one of the treatment strategies in these patients, but disagreement about these interventions and their results has led to their limited use. Therefore, this study aimed to identify nonpharmacological interventions and their consequences in these patients.
MATERIALS AND METHODS
We followed the Cochrane Handbook for systematic reviews of interventions. The present report is organized according to the preferred reporting items for systematic reviews and meta-analyses. This study was conducted at PubMed, Cochrane Library, Web of Science, and Scopus, among all published studies by December 30, 2021. Keywords were: HTLV-1, Human T-lymph tropic virus 1, HTLV-I-associated myelopathy, HAM/TSP, tropical spastic paraparesis, nonpharmacological intervention, nonpharmacological treatment, massage, physiotherapy, acupuncture, acupressure, and exercise. The quality of the studies was assessed using JADAD.
RESULTS
Of 288 articles, 11 were eligible for data extraction published between 2014 and 2021. 90/9% of studies were randomized clinical trials. 81/8% of articles were of high quality. The total sample size was 253 people, of which 137 (54/15%) were women. Approaches such as exercise and motion therapy, electrotherapy, behavioral therapy, and virtual reality can be used for these patients. With these interventions, results such as improved mobility and balance, physical condition, pain, quality of life, muscle spasticity, maximum inspiratory pressure, and urinary symptoms can be achieved.
CONCLUSION
The most common physical therapy method used in studies was active and passive body movements, which are associated with positive results for patients. Due to the small sample size in this group of studies, it is necessary to conduct more clinical trials for more accurate conclusions. Furthermore, due to the limited number of studies that have used electrical stimulation or combined intervention packages, it is not possible to say with certainty what effect these methods have on patients. It is necessary to conduct more clinical trials.

Meta-Analysis Review
BACKGROUND
Peak oxygen uptake (VO2peak) in Paralympic sitting sports athletes represents their maximal ability to deliver energy aerobically in an upper-body mode, with values being influenced by sex, disability-related physiological limitations, sport-specific demands, training status and how they are tested.
OBJECTIVES
To identify VO2peak values in Paralympic sitting sports, examine between-sports differences and within-sports variations in VO2peak and determine the influence of sex, age, body-mass, disability and test-mode on VO2peak.
DESIGN
Systematic literature review and meta-analysis.
DATA SOURCES
PubMed, CINAHL, SPORTDiscusTM and EMBASE were systematically searched in October 2016 using relevant medical subject headings, keywords and a Boolean.
ELIGIBILITY CRITERIA
Studies that assessed VO2peak values in sitting sports athletes with a disability in a laboratory setting were included.
DATA SYNTHESIS
Data was extracted and pooled in the different sports disciplines, weighted by the Dersimonian and Laird random effects approach. Quality of the included studies was assessed with a modified version of the Downs and Black checklist by two independent reviewers. Meta-regression and pooled-data multiple regression analyses were performed to assess the influence of sex, age, body-mass, disability, test mode and study quality on VO2peak.
RESULTS
Of 6542 retrieved articles, 57 studies reporting VO2peak values in 14 different sitting sports were included in this review. VO2peak values from 771 athletes were used in the data analysis, of which 30% participated in wheelchair basketball, 27% in wheelchair racing, 15% in wheelchair rugby and the remaining 28% in the 11 other disciplines. Fifty-six percent of the athletes had a spinal cord injury and 87% were men. Sports-discipline-averaged VO2peak values ranged from 2.9 L∙min-1 and 45.6 mL∙kg-1∙min-1 in Nordic sit skiing to 1.4 L∙min-1 and 17.3 mL∙kg-1∙min-1 in shooting and 1.3 L∙min-1 and 18.9 mL∙kg-1∙min-1 in wheelchair rugby. Large within-sports variation was found in sports with few included studies and corresponding low sample sizes. The meta-regression and pooled-data multiple regression analyses showed that being a man, having an amputation, not being tetraplegic, testing in a wheelchair ergometer and treadmill mode, were found to be favorable for high absolute and body-mass normalized VO2peak values. Furthermore, high body mass was favourable for high absolute VO2peak values and low body mass for high body-mass normalized VO2peak values.
CONCLUSION
The highest VO2peak values were found in Nordic sit skiing, an endurance sport with continuously high physical efforts, and the lowest values in shooting, a sport with low levels of displacement, and in wheelchair rugby where mainly athletes with tetraplegia compete. However, VO2peak values need to be interpreted carefully in sports-disciplines with few included studies and large within-sports variation. Future studies should include detailed information on training status, sex, age, test mode, as well as the type and extent of disability in order to more precisely evaluate the effect of these factors on VO2peak.

Meta-Analysis Review
BACKGROUND
Human T-lymphotropic virus type 1 (HTLV-1) is considered to be the etiological agent of adult T-cell leukemia/lymphoma (ATL) and HTLV-associated myelopathy/tropical spastic paraparesis (HAM/TSP). Blood transfusion is a common transmission pathway for HTLV-1. However, no surveys to determine the overall prevalence of HTLV-1 infection and HTLV-1 genotypes among blood donors on the Chinese mainland have yet been conducted.
METHODS
A systematic review and meta-analysis of the peer-reviewed literature on this topic was carried out. Data manipulation and statistical analyses were performed using the Comprehensive Meta Analysis Version 2.0 program.
RESULTS
Forty-four eligible articles involving 458525 blood donors were selected. Analysis revealed the pooled prevalences of HTLV-1 infection among blood donors in Fujian and Guangdong provinces to be 9.9/10000 (95% confidence interval (CI) 4.4/10000-22.2/10000) and 2.9/10000 (95% CI 1.7/10000-4.8/10000), respectively; there were only two cases of HTLV-1 infection among 204763 donors in other areas of the Chinese mainland. In addition, 40 of 42 (95.2%) HTLV-1 isolates belonged to the Transcontinental subgroup A of the HTLV-1 subtype A (Cosmopolitan subtype).
CONCLUSIONS
The prevalence of HTLV-1 infection among blood donors is low and restricted mainly to the provinces of Fujian and Guangdong. Most isolates belong to the Transcontinental subgroup within HTLV-1 subtype A.

Comparative Study Meta-Analysis
Comparison of the efficacy and safety of thoracic endovascular aortic repair with open surgical repair and optimal medical therapy for acute type B aortic dissection: A systematic review and meta-analysis.
BACKGROUND
Current treatment approaches for acute type B aortic dissection (TBAD) are diversified. Thoracic endovascular aortic repair (TEVAR) as an effective and convenient intervention has been adopted extensively. However, the superior efficacy and safety of TEVAR have not yet been well evaluated. This meta-analysis was designed to comprehensively compare the efficacy and safety of TEVAR with open surgical repair and optimal medical therapy for acute type B aortic dissection.
METHODS
A systematic search of PubMed, Embase, Cochrane Library and Web of Science up to April 1, 2020 was conducted for relevant studies that compared the efficacy of TEVAR and other conventional interventions in the treatment of TBAD. The primary outcomes were early mortality and midterm or long term survival. The secondary outcomes included early complications and other late outcomes. Two reviewers assessed trial quality and extracted the data independently. All statistical analyses were performed using the standard statistical procedures provided in Review Manager 5.2.
RESULTS
A total of 18 studies including 12,789 patients were identified. 30-day/in-hospital mortality was significantly lower in TBAD patients with TEVAR than open surgical repair (OSR), with a pooled OR of 0.54 (95% CI 0.43-0.68; P < 0.00001). Compared with optimal medical therapy (OMT), TEVAR experienced lower incidence of long-term death (≥5-yr mortality), with a pooled OR of 0.46 (95% CI 0.24-0.86; P = 0.02). However, no significant difference between TEVAR and OSR or OMT in long-term survival was found. Compared with OSR, lower incidence of cardiac and pulmonary complications as well as shorter length of stay were observed in TEVAR. Compared with OMT, TEVAR showed higher rate of paraplegia or paraparesis, higher complete thrombosis of the false lumen, as well as longer length of ICU stay.
CONCLUSIONS
Our analysis shows that TEVAR may be favorable in reducing 30-day/in-hospital mortality (than OSR) and long-term mortality (than OMT). TEVAR experienced equal efficacy with OSR and OMT in long-term survival. TEVAR showed higher rate of paraplegia or paraparesis, higher complete thrombosis of the false lumen, as well as longer length of ICU stay than OMT; and lower incidence of cardiac and pulmonary complications as well as shorter length of stay than OSR. However, TEVAR indicated similar incidence of other complications and outcomes with OSR and OMT. Further studies especially randomized clinical trials are needed to comprehensively compare the efficacy TEVAR.

Review
BACKGROUND
Intramedullary melanocytomas are exceedingly rare, with only twenty-four cases reported up to now. They present as local invasive tumors despite their benign biological behavior. Attempting a complete safe resection often results in severe post-operative neurological deficits, as in our case presented here.
METHODS
A systematic review was conducted across the PubMed and Scopus databases including studies published till February 2024.
RESULTS
A total of 19 studies were included, encompassing 24 cases. A similar distribution between sexes was noted (M:F 13:11), with ages ranging from 19 to 79 years. The thoracic segment was most affected, and intermediate-grade melanocytoma (19 cases) was the most common histotype. Radiographically, intramedullary melanocytomas usually appear as hyperintense hemorrhagic lesions peripheral to the central canal with focal nodular enhancement. Intraoperatively, they are black-reddish to tan and are tenaciously adherent lesions. In the sampled studies, IONM employment was uncommon, and post-operative new-onset neurological deficits were described in 16 cases. Adjuvant RT was used in four cases and its value is debatable. Recurrence is common (10 cases), and adjuvant therapies (RT or repeated surgery) seem to play a palliative role.
CASE PRESENTATION
A 68-year-old woman presented with a three-year history of worsening spastic paraparesis and loss of independence in daily activities (McCormick grade 4). An MRI revealed an intramedullary tumor from Th5 to Th7, characterized by T1-weighted hyperintensity and signs of recent intralesional hemorrhage. Multimodal neuromonitoring, comprising the D-Wave, guided the resection of a black-tan-colored tumor with hyper-vascularization and strong adherence to the white matter. During final dissection of the lesion to obtain gross total resection (GTR), a steep decline in MEPs and D-Wave signals was recorded. Post-operatively, the patient had severe hypoesthesia with Th9 level and segmental motor deficits, with some improvement during neurorehabilitation. Histopathology revealed an intermediate-grade melanocytoma (CNS WHO 2021 classification). A four-month follow-up documented the absence of relapse.
CONCLUSIONS
This literature review highlights that intramedullary T1 hyperintense hemorrhagic thoracic lesions in an adult patient should raise the suspicion of intramedullary melanocytoma. They present as locally aggressive tumors, due to local invasiveness, which often lead to post-operative neurological deficits, and frequent relapses, which overwhelm therapeutic strategies leading to palliative care after several years.

Review
We reviewed the evidence on features of central nervous system (CNS) involvement in trichinellosis, systematically searching five databases (to January 2021). We categorized clinical features based on their diagnostic value as warning signs for severe CNS infection (with outcome death) or non-specific signs (outcome improvement). They were suggestive of severe infection if they substantially raised death probability. The review included 87 papers published from 1906 through 2019, with data on 168 patients. Mydriasis, paraparesis, dysphagia, psychomotor seizures, or delirium present a 30-45% increased death likelihood. The best poor prognosis predictor is mydriasis (positive likelihood ratio 9.08). Slow/absent light reflex, diminished/absent knee reflexes, globally decreased tendon reflexes present a moderate increase (20-25%) of death risk. Anisocoria, acalculia, or seizures could also indicate an increased death risk. We provided a detailed presentation of clinical and paraclinical signs that alert physicians of a possible neurotrichinellosis, emphasizing signs that might indicate a poor prognosis.

Neurology(R) Neuroimmunology &... May 2021To define the characteristics and the outcome of myelitis associated with immune checkpoint inhibitors (ICIs).
OBJECTIVE
To define the characteristics and the outcome of myelitis associated with immune checkpoint inhibitors (ICIs).
METHODS
We performed a retrospective research in the databases of the French Pharmacovigilance Agency and the OncoNeuroTox network for patients who developed myelitis following treatment with ICIs (2011-2020). A systematic review of the literature was performed to identify similar cases.
RESULTS
We identified 7 patients who developed myelitis after treatment with ICIs (anti-PD1 [n = 6], anti-PD1 + anti-CTLA4 [n = 1]). Neurologic symptoms included paraparesis (100%), sphincter dysfunction (86%), tactile/thermic sensory disturbances (71%), and proprioceptive ataxia (43%). At the peak of symptom severity, all patients were nonambulatory. MRI typically showed longitudinally extensive lesions, with patchy contrast enhancement. CSF invariably showed inflammatory findings. Five patients (71%) had clinical and/or paraclinical evidence of concomitant cerebral, meningeal, caudal roots, and/or peripheral nerve involvement. Despite the prompt discontinuation of ICIs and administration of high-dose glucocorticoids (n = 7), most patients needed second-line immune therapies (n = 5) because of poor recovery or early relapses. At last follow-up, only 3 patients had regained an ambulatory status (43%). Literature review identified 13 previously reported cases, showing similar clinical and paraclinical features. All patients discontinued ICIs and received high-dose glucocorticoids, with the addition of other immune therapies in 8. Clinical improvement was reported for 10 patients.
CONCLUSION
Myelitis is a rare but severe complication of ICIs that shows limited response to glucocorticoids. Considering the poor functional outcome associated with longitudinally extensive myelitis, strong and protracted immune therapy combinations are probably needed upfront to improve patient outcome and prevent early relapses.

Review
There are great diversities of clinical phenotypes among the various familial Alzheimer's disease (FAD) families. We aimed to systematically review all the previously reported cases of FAD and to perform comparisons between Asian and white patients. In this regard, we collected individual-level data from 658 pedigrees. We found that patients with presenilin 1 (PSEN1) mutations had the earliest age of onset (AOO; 43.3 ± 8.6 years, p < 0.001) and were more commonly affected by seizures, spastic paraparesis, myoclonus, and cerebellar signs (p < 0.001, p < 0.001, p = 0.003, and p = 0.002, respectively). Patients with PSEN2 mutations have a delayed AOO with longest disease duration and presented more frequently with disorientation (p = 0.03). Patients with amyloid precursor protein (APP) mutations presented more frequently with aggression (p = 0.02) and those with APP duplication presented more frequently with apraxia (p = 0.03). PSEN1 mutations before codon 200 had an earlier AOO than those having mutations after codon 200 (41.4 ± 8.0 years vs. 44.7 ± 8.7 years, p < 0.001). Because 42.9% of the mutations reported are novel, the mutation spectrum and clinical features in Asian FAD families could be different from that of whites. Asian patients with PSEN1 mutations presented more frequently with disorientation (p = 0.02) and personality change (p = 0.01) but less frequently with atypical clinical features. Asian patients with APP mutations presented less frequently with aphasia (p = 0.02). Thus, clinical features could be modified by underlying mutations, and Asian FAD patients may have different clinical features when compared with whites.

Review
OBJECTIVE
To describe the pain in patients infected with human T-cell lymphotropic virus type 1, clinically and epidemiologically.
METHODS
This systematic review was based on The PRISMA Statement. Four reviewers searched PUBMED, SciELO, LILACS and BIREME for data from observational studies and clinical trials (n≥30) regarding pain prevalence, characteristics, and associated factors in patients with human T-cell lymphotropic virus type 1. No limits on publication date or language were established. Studies that did not have pain as an outcome measure or not involving human T-cell lymphotropic virus type 1 infected patients were excluded.
RESULTS
A total of 3013 articles (including duplicates) were found of which seven met the predetermined criteria. The most common pain region was the lower back (53.0%). Non-neuropathic type (ranging from 52.6% to 86.8%) was more frequent in human T-cell lymphotropic virus type 1-associated myelopathy/tropical spastic paraparesis participants, and neuropathic pain was more common in human T-cell lymphotropic virus type 1 carriers (53.1%). The pain was mostly reported as moderate or severe. One study showed that chronic pain was negatively associated with quality of life.
DISCUSSION
Pain is a common complaint in human T-cell lymphotropic virus type 1 infected patients, with lower back pain as the most frequent site. Pain can either be nociceptive, neuropathic, or both, is frequently severe, and negatively affects quality of life. Only studies of two countries were included in this review, limiting the external validity of the conclusions. The heterogeneity of variables prevented us from implementing a meta-analysis. Further research should better characterize the pain and explore its impact on quality of life, especially using longitudinal study design.
