Meta-Analysis Review
OBJECTIVE
Human T-cell lymphotropic virus type-1 (HTLV-1) infection is a neglected tropical disease associated with many clinical manifestations, such as erythematous-scaling skin lesions, cutaneous lymphomas, and spastic paraparesis, which could be a potential cause of mental health concerns. This study investigates the prevalence of symptoms and diagnoses of depression and anxiety and its associated factors in people living with HTLV-1 (PLWH).
METHOD
A systematic review was performed in the Pubmed/MEDLINE, Embase, LILACS, and PsycINFO databases for original studies investigating symptoms of depression and anxiety and diagnoses of major depressive disorder and anxiety disorders in PLWH, and a random-effects meta-analysis with meta-regression was performed to obtain a summary frequency of symptoms and diagnoses of depression and anxiety.
RESULTS
Considering both symptoms and diagnoses, the pooled prevalence for depression was 35% (95% CI: 27 to 43) and for anxiety was 33% (95% CI: 23 to 45). Clinically significant symptoms were more prevalent than diagnosed disorders for depression (47% vs. 21%) and anxiety (44% vs. 11%). PLWH were more likely than seronegative controls to present symptoms and diagnoses of depression (pooled OR: 4.25; 95% CI: 2.7 to 6.68) and anxiety (pooled OR: 3.79; 95% CI: 2.6 to 5.52). Spastic paraparesis was significantly associated with symptoms and diagnoses of depression (pooled OR: 1.81; 95% CI: 1.11 to 2.95) and anxiety (pooled OR: 2.75; 95% CI 1.26 to 5.96).
CONCLUSIONS
PLWH present a much higher prevalence of symptoms and diagnoses of depression and anxiety than seronegative controls, which could be explained by social vulnerability or neurological impairment associated with spastic paraparesis. More studies comparing asymptomatic PLWH and seronegative controls are needed.

Review
BACKGROUND
Intramedullary meningiomas are an exceptionally rare subtype of spinal tumors, accounting for only 5% of primary spinal neoplasms. Given their scarcity and unique characteristics, understanding optimal management approaches is crucial for improved clinical decision-making. This systematic review aims to consolidate existing literature and present a detailed case illustration to enhance understanding of this uncommon spinal tumor entity.
METHODS
A systematic search adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was conducted. Eligible studies included case reports, case series, cohort studies, reviews, and meta-analyses. Data extraction and synthesis focused on demographic characteristics, tumor location, clinical presentation, imaging findings, surgical interventions, histopathological features, and outcomes.
RESULTS
A total of 15 high-quality scientific articles were included in the systematic review, providing insights into various aspects of intramedullary meningiomas. Demographic analysis revealed a broad age distribution with an equal gender distribution among affected patients. Common clinical presentations included difficulty walking, sensory disturbances, spastic paraparesis, and urinary incontinence. Neuroimaging findings demonstrated heterogeneous signal intensity variations on T1- and T2-weighted images, with variable enhancement patterns on gadolinium-enhanced images. Surgical interventions, predominantly total resection, resulted in favorable postoperative outcomes in most cases.
CONCLUSIONS
Intramedullary meningiomas pose diagnostic and therapeutic challenges due to their rarity and unique characteristics. Tailored surgical approaches, incorporating techniques such as intraoperative neurophysiological monitoring and fluorescence-aided resection, are crucial for minimizing neurological deficits and optimizing patient outcomes. Despite their infrequency, recognizing intramedullary meningiomas in the differential diagnosis of spinal tumors is essential for prompt diagnosis and timely intervention, ultimately improving patient prognosis.

Global Spine Journal Dec 2018Systematic review.
STUDY DESIGN
Systematic review.
OBJECTIVES
Past research has demonstrated increased speed and severity of progression for spinal epidural abscesses (SEAs) of the thoracic level, specifically, when compared with SEAs of other spinal cord levels. Untreated, this infection can result in permanent neurological sequelae with eventual progression to death if inadequately managed. Despite the seriousness of this disease, no articles have focused on the presentation, diagnosis, and treatment of SEAs of the thoracic level. For this reason, specific focus on SEAs of the thoracic level occurred when researchers designed and implemented the following systematic review.
METHODS
A query of Ovid-Medline and EMBASE, Cochrane Central, and additional review sources was conducted. Search criteria focused on articles specific to thoracic epidural abscesses.
RESULTS
Twenty-five articles met inclusion criteria. The most commonly reported symptoms present on admission included back pain, paraparesis/paraplegia, fever, and loss of bowel/bladder control. Significant risk factors included diabetes, intravenous drug use, and advanced age ( = .001). Patients were most often treated surgically with either laminectomy, hemilaminectomy, or radical decompression with debridement. Patients who presented with neurological deficits and had delayed surgical intervention following a failed antibiotic course tended to do worse compared with their immediate surgical management counterparts ( < .005).
CONCLUSIONS
For the first time researchers have focused specifically on SEAs of the thoracic level, as opposed to previously published general analysis of SEAs as a whole. Based on the results, investigators recommend early magnetic resonance imaging of the spine, laboratory workup (sedimentation rate/C-reactive protein, complete blood count), abscess culture followed by empiric antibiotics, and immediate surgical decompression when neurological deficits are present.

Review
Cerebral and spinal cord changes observed through magnetic resonance imaging in patients with HTLV-1-associated myelopathy/tropical spastic paraparesis: a systematic review.
To verify brain and spinal changes using magnetic resonance imaging in patients with HTLV-1-associated myelopathy/tropical spastic paraparesis. This was a systematic review. The descriptors used were tropical spastic paraparesis and magnetic resonance image. The keyword HTLV-1-associated myelopathy was also used. Twenty-three articles were included: 16 detected brain changes and 18 detected spinal changes. White matter lesions were the most frequent finding in the brain. Brain injuries were most frequently identified in the periventricular region, in the subcortical region, in the centrum semiovale, in the brain stem, and corpus callosum. Atrophy was the most frequent finding of the spinal cord, affecting the thoracic and cervical regions, and was associated with a longer evolution of myelopathy. White matter lesions in these regions were also observed. Cortical white matter lesions and thoracic spinal cord atrophy were the most frequently reported changes in patients with HTLV-1-associated myelopathy.

Alzheimer's disease (AD) is the most common cause of dementia, characterized by progressive loss of cognitive function, with β-amyloid plaques and neurofibrillary tangles being its major pathological findings. Although the disease mainly affects the elderly, c. 5-10% of the cases are due to , , and mutations, principally associated with an early onset of the disease. The A413E (rs63750083) variant, identified in 2001, is associated with early-onset Alzheimer's disease (EOAD). Although there is scant knowledge about the disease's clinical manifestations and particular features, significant clinical heterogeneity was reported, with a high incidence of spastic paraparesis (SP), language impairments, and psychiatric and motor manifestations. This scoping review aims to synthesize findings related to the A431E variant of In the search, we followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement and the guidelines proposed by Arksey and O'Malley. We searched and identified 247 studies including the A431E variant of from 2001 to 2021 in five databases and one search engine. After the removal of duplicates, and apply inclusion criteria, 42 studies were finally included. We considered a narrative synthesis with a qualitative approach for the analysis of the data. Given the study sample conformation, we divided the results into those carried out only with participants carrying A431E (seven studies), subjects with variants (11 studies), and variants associated with EOAD in , , and (24 studies). The resulting synthesis indicates most studies involve Mexican and Mexican-American participants in preclinical stages. The articles analyzed included carrier characteristics in categories such as genetics, clinical, imaging techniques, neuropsychology, neuropathology, and biomarkers. Some studies also considered family members' beliefs and caregivers' experiences. Heterogeneity in both the studies found and carrier samples of EOAD-related gene variants does not allow for the generalization of the findings. Future research should focus on reporting data on the progression of carrier characteristics through time and reporting results independently or comparing them across variants.

We aimed to verify the influence of intrinsic and extrinsic cell apoptotic pathways on the inhibition of cellular apoptosis in patients with tropical spastic paralysis/myelopathy related to human T cell lymphotropic virus type 1. The databases accessed were PubMed, Scopus, Science Direct, and Web of Science. Neither the time of publishing nor the language of the articles was limited. The descriptors used for this systematic literature review were: Tropical Paraparesis, Proto-Oncogenic Protein C, Bcl-2, Bcl-X Protein, Bax protein, Fas ligand (FasL) protein, Fas receptor, TNF-related apoptosis-inducing ligand and Fas-associated protein with death domain (FADD)-like apoptosis regulating. The search resulted in 546 articles from which 9 articles were selected for analysis; ranging from serum levels of Bcl-2, Fas and tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) measured by enzyme-linked immunosorbent assay and the levels of cellular expression of Bcl-2 and Bcl-xL the TCD4+ lymphocytes accessed by western blot. Most studies accessed either gene expression or polymorphism of Fas, FasL, and TRAIL in patients with HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP), whereas one study used flow cytometry and fluorescence to determine Fas expression. Increased Bcl-xL expression inhibited T lymphocyte apoptosis, whereas Bcl-2, serum levels, and cellular expression did not influence T lymphocyte apoptosis and serum levels of Fas were significantly higher and associated with markers of leukocyte activation in patients with HAM/TSP. In addition, Fas polymorphism (FAS-670AA) was associated with higher proviral load. There is a need for additional research on this issue since the number of patients was small and the studies presented higher heterogeneity.

Review
OBJECTIVE
Spinal metastases from primary intracranial glioblastoma (GBM) are infrequently reported, and the disease has yet to be well characterized. A more accurate description of its clinical presentation and patient survival may improve understanding of this pathology, guide patient care, and advocate for increased inclusion in GBM research. The authors sought to describe the clinical presentation, treatment patterns, and survival in patients with drop metastases secondary to primary intracranial GBM.
METHODS
A systematic review was performed using the PRISMA guidelines. PubMed/MEDLINE, Scopus, Web of Science, and Cochrane databases were queried for abstracts that included patients with primary intracranial GBM and metastases to the spinal axis. Descriptive statistics were used to evaluate characteristics of the primary brain lesion, timing of spinal metastases, clinical symptoms, anatomical location of the metastases, and survival and treatment parameters. Kaplan-Meier analysis and log-rank analysis of the survival curves were performed for selected subgroups.
RESULTS
Of 1225 abstracts that resulted from the search, 51 articles were selected, yielding 86 subjects. The patients' mean age was 46.78 years and 59.74% were male. The most common symptom was lumbago or cervicalgia (90.24%), and this was followed by paraparesis (86.00%). The actuarial median survival after the detection of spinal metastases was 2.8 months and the mean survival was 2.72 months (95% CI 2.59-4.85), with a 1-year cumulative survival probability of 2.7% (95% CI 0.51%-8.33%). A diagnosis of leptomeningeal disease, present in 53.54% of the patients, was correlated, and significantly worse survival was on log-rank analysis in patients with leptomeningeal disease (p = 0.0046; median survival 2.5 months [95% CI 2-3] vs 4.0 months [95% CI 2-6]).
CONCLUSIONS
This study established baseline characteristics of GBMs metastatic to the spinal axis. The prognosis is poor, though these results will provide patients and clinicians with more accurate survival estimates. The quality of studies reporting on this disease pathology is still limited. There is significant need for improved reporting methods for spinal metastases, either through enrollment of these patients in clinical trials or through increased granularity of coding for metastatic central nervous system diseases in cancer databases.

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.

BACKGROUND
Intramedullary spinal cord cavernous malformations (SCCMs) account for only 5% of overall cavernous malformations (CMs). The occurrence of recurrent or residual SCCMs has not been well discussed, nor have the technical nuances of resection.
OBJECTIVE
To assess the characteristics of residual SCCMs and surgical outcomes and describe the techniques to avoid leaving lesion remnants during primary resection.
METHODS
Demographic, radiologic, intraoperative findings and surgical outcomes data for a cohort of surgically managed intramedullary SCCMs were obtained from an institutional database and retrospectively analyzed. A systematic literature review was performed using PRISMA guidelines.
RESULTS
Of 146 SCCM resections identified, 17 were for residual lesions (12%). Patients with residuals included 13 men and 4 women, with a mean age of 43 years (range 16-70). All patients with residual SCCMs had symptomatic presentations: sensory deficits, paraparesis, spasticity, and pain. Residuals occurred between 3 and 264 months after initial resection. Approaches for 136 cases included posterior midline myelotomy (28.7%, n = 39), pial surface entry (37.5%, n = 51), dorsal root entry zone (27.9%, n = 38), and lateral entry (5.9%, n = 8). Follow-up outcomes were similar for patients with primary and residual lesions, with the majority having no change in modified Rankin Scale score (63% [59/93] vs 75% [9/12], respectively, P = .98).
CONCLUSION
SCCMs may cause significant symptoms. During primary resection, care should be taken to avoid leaving residual lesion remnants, which can lead to future hemorrhagic events and neurological morbidity. However, satisfactory results are achievable even with secondary or tertiary resections.

Review
Human T-lymphotropic virus 1 (HTLV-1) is a retrovirus that produces a persistent infection. Two transmission routes (from mother to child and via sexual intercourse) favor familial clustering of HTLV-1. It is yet unknown why most HTLV-1 carriers remain asymptomatic while about 10% of them develop complications. HTLV-1 associated diseases were originally described as sporadic entities, but familial presentations have been reported. To explore what is known about family aggregation of HTLV-1-associated diseases we undertook a systematic review. We aimed at answering whether, when, and where family aggregation of HTLV-1-associated diseases was reported, which relatives were affected and which hypotheses were proposed to explain aggregation. We searched MEDLINE, abstract books of HTLV conferences and reference lists of selected papers. Search terms used referred to HTLV-1 infection, and HTLV-1-associated diseases, and family studies. HTLV-1-associated diseases considered are adult T-cell leukemia/lymphoma (ATLL), HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP), HTLV-1-associated uveitis, and infective dermatitis. Seventy-four records reported HTLV-1-associated diseases in more than one member of the same family and were included. Most reports came from HTLV-1-endemic countries, mainly Japan ( = 30) and Brazil ( = 10). These reports described a total of 270 families in which more than one relative had HTLV-1-associated diseases. In most families, different family members suffered from the same disease ( = 223). The diseases most frequently reported were ATLL (115 families) and HAM/TSP (102 families). Most families ( = 144) included two to four affected individuals. The proportion of ATLL patients with family history of ATLL ranged from 2 to 26%. The proportion of HAM/TSP patients with family history of HAM/TSP ranged from 1 to 48%. The predominant cluster types for ATLL were clusters of siblings and parent-child pairs and for HAM/TSP, an affected parent with one or more affected children. The evidence in the literature, although weak, does suggest that HTLV-1-associated diseases sometimes cluster in families. Whether familial transmission of HTLV-1 is the only determining factor, or whether other factors are also involved, needs further research.
