RESUMO
Frontotemporal dementia (FTD) is the second most common cause of early-onset dementia after Alzheimer disease (AD). Efforts in the field mainly focus on familial forms of disease (fFTDs), while studies of the genetic etiology of sporadic FTD (sFTD) have been less common. In the current work, we analyzed 4,685 sFTD cases and 15,308 controls looking for common genetic determinants for sFTD. We found a cluster of variants at the MAPT (rs199443; p = 2.5 × 10-12, OR = 1.27) and APOE (rs6857; p = 1.31 × 10-12, OR = 1.27) loci and a candidate locus on chromosome 3 (rs1009966; p = 2.41 × 10-8, OR = 1.16) in the intergenic region between RPSA and MOBP, contributing to increased risk for sFTD through effects on expression and/or splicing in brain cortex of functionally relevant in-cis genes at the MAPT and RPSA-MOBP loci. The association with the MAPT (H1c clade) and RPSA-MOBP loci may suggest common genetic pleiotropy across FTD and progressive supranuclear palsy (PSP) (MAPT and RPSA-MOBP loci) and across FTD, AD, Parkinson disease (PD), and cortico-basal degeneration (CBD) (MAPT locus). Our data also suggest population specificity of the risk signals, with MAPT and APOE loci associations mainly driven by Central/Nordic and Mediterranean Europeans, respectively. This study lays the foundations for future work aimed at further characterizing population-specific features of potential FTD-discriminant APOE haplotype(s) and the functional involvement and contribution of the MAPT H1c haplotype and RPSA-MOBP loci to pathogenesis of sporadic forms of FTD in brain cortex.

The NF-κB pathway is involved in the pathogenesis of neurological disorders that have inflammation as a hallmark, including Parkinson's disease (PD). Our objective was to determine whether common functional variants in the NFKB1, NFKBIA and NFKBIZ genes were associated with the risk of PD. A total of 532 Spanish PD cases (61% male; 38% early-onset, ≤ 55 years) and 300 population controls (50% ≤55 years) were genotyped for the NFKB1 rs28362491 and rs7667496, NFKBIA rs696, and NFKBIZ rs1398608 polymorphisms. We compared allele and genotype frequencies between early and late-onset, male and female, and patient's vs. controls. We found that the two NFKB1 alleles were significantly associated with PD in our population (p = 0.01; total patients vs. controls), without difference between Early and Late onset patients. The frequencies of the NFKB1 variants significantly differ between male and female patients. Compared to controls, male patients showed a significantly higher frequency of rs28362491 II (p = 0.02, OR = 1.52, 95%CI = 1.10-2.08) and rs28362491 C (p = 0.003, OR = 1.62, 95%CI = 1.18-2.22). The two NFKB1 variants were in strong linkage disequilibrium and the I-C haplotype was significantly associated with the risk of PD among male (p = 0.002). In conclusion, common variants in the NF-kB genes were associated with the risk of developing PD in our population, with significant differences between male and female. These results encourage further studies to determine the involvement of the NF-kB components in the pathogenesis of Parkinson´s disease.

Previous studies have suggested a relationship between the number of CAG triplet repeats in the HTT gene and neurodegenerative diseases not related to Huntington's disease (HD). This study seeks to investigate whether the number of CAG repeats of HTT is associated with the risk of developing certain tauopathies and its influence as a modulator of the clinical and neuropathological phenotype. Additionally, it aims to evaluate the potential of polyglutamine staining as a neuropathological screening. We genotyped the HTT gene CAG repeat number and APOE-â° isoforms in a cohort of patients with neuropathological diagnoses of tauopathies (n=588), including 34 corticobasal degeneration (CBD), 98 progressive supranuclear palsy (PSP) and 456 Alzheimer's disease (AD). Furthermore, we genotyped a control group of 1070 patients, of whom 44 were neuropathologic controls. We identified significant differences in the number of patients with pathological HTT expansions in the CBD group (2.7%) and PSP group (3.2%) compared to control subjects (0.2%). A significant increase in the size of the HTT CAG repeats was found in the AD compared to the control group, influenced by the presence of the Apoliprotein E (APOE)-â°4 isoform. Post-mortem assessments uncovered tauopathy pathology with positive polyglutamine aggregates, with a slight predominance in the neostriatum for PSP and CBD cases and somewhat greater limbic involvement in the AD case. Our results indicated a link between HTT CAG repeat expansion with other non-HD pathology, suggesting they could share common neurodegenerative pathways. These findings support that genetic or histological screening for HTT repeat expansions should be considered in tauopathies.

BACKGROUND: Computer-aided detection (CADe) systems for colonoscopy have been shown to increase small polyp detection during colonoscopy in the general population. People with Lynch syndrome represent an ideal target population for CADe-assisted colonoscopy because adenomas, the primary cancer precursor lesions, are characterised by their small size and higher likelihood of showing advanced histology. We aimed to evaluate the performance of CADe-assisted colonoscopy in detecting adenomas in individuals with Lynch syndrome. METHODS: TIMELY was an international, multicentre, parallel, randomised controlled trial done in 11 academic centres and six community centres in Belgium, Germany, Italy, and Spain. We enrolled individuals aged 18 years or older with pathogenic or likely pathogenic MLH1, MSH2, MSH6, or EPCAM variants. Participants were consecutively randomly assigned (1:1) to either CADe (GI Genius) assisted white light endoscopy (WLE) or WLE alone. A centre-stratified randomisation sequence was generated through a computer-generated system with a separate randomisation list for each centre according to block-permuted randomisation (block size 26 patients per centre). Allocation was automatically provided by the online AEG-REDCap database. Participants were masked to the random assignment but endoscopists were not. The primary outcome was the mean number of adenomas per colonoscopy, calculated by dividing the total number of adenomas detected by the total number of colonoscopies and assessed in the intention-to-treat population. This trial is registered with ClinicalTrials.gov, NCT04909671. FINDINGS: Between Sept 13, 2021, and April 6, 2023, 456 participants were screened for eligibility, 430 of whom were randomly assigned to receive CADe-assisted colonoscopy (n=214) or WLE (n=216). 256 (60%) participants were female and 174 (40%) were male. In the intention-to-treat analysis, the mean number of adenomas per colonoscopy was 0·64 (SD 1·57) in the CADe group and 0·64 (1·17) in the WLE group (adjusted rate ratio 1·03 [95% CI 0·72-1·47); p=0·87). No adverse events were reported during the trial. INTERPRETATION: In this multicentre international trial, CADe did not improve the detection of adenomas in individuals with Lynch syndrome. High-quality procedures and thorough inspection and exposure of the colonic mucosa remain the cornerstone in surveillance of Lynch syndrome.

Objetivo: Describir los factores asociados con niveles de dolor mas severo en una cohorte de pacientes con fascitis plantar. El objetivo secundario fue analizar cuales de estos factores estaban asociados con niveles mas altos de mejoria clinica luego del tratamiento conservador. Materiales y Métodos: Se evaluo a una cohorte prospectiva de pacientes con diagnostico de fascitis plantar. Cada participante completo una escala ordinal visual de dolor (del 1 al 10) para dolor del primer paso y dolor al final del dia y encuestas FFI-R (Foot Function Index-Revised). Tambien se realizo una evaluacion demografica. La dorsiflexion de la articulacion del tobillo, el rango de movilidad de la primera articulacion metatarsofalangica, la rigidez del gastrocnemio y el angulo popliteo tambien se evaluaron de manera estandar. Resultados: Se incluyo a 214 pacientes. El 64% eran hombres (118 pacientes), la media de la edad era de 49.67 anos (DE 13.16) y el indice de masa corporal promedio, de 28,53 (DE 5,18). En el analisis multivariado, se observo que el riesgo de un puntaje ≥8 en la escala de dolor aumento cuando el paciente refirio estar de pie por mas de 6 h (OR 1,17; p = 0,03; IC95% 1,02-1,35). El riesgo de un puntaje >8 fue mayor cuando el grado de dorsiflexion del tobillo fue <0° (OR 1,20; p = 0,03; IC95% 1,02-1,41). Conclusión: Nuestros hallazgos apoyan indirectamente la hipotesis de que la dorsiflexion limitada del tobillo juega un papel como factor de riesgo asociado a un puntaje ≥8 en la escala de dolor, en los casos de fascitis plantar. Nivel de Evidencia: IV
Objective: The main purpose of our study was to describe the factors associated with more severe pain levels in a cohort of patients with plantar fasciitis (PF). The secondary purpose of this study was to determine which of these factors were associated with higher levels of clinical improvement after conservative therapy. Materials and Methods: We conducted a prospective study in a cohort of patients with PF. Each participant completed an ordinal pain scale (1-10) for first-step pain and end-of-day pain, and Foot Function Index-Revised (FFI-R) surveys at enrollment. Also, patient demographics were evaluated. The ankle joint dorsiflexion, the range of motion (ROM) for the first metatarsophalangeal joint (MTPJ), the gastrocnemius tightness, and the popliteal angle were evaluated through standard tests. Results: Our study included 214 participants, of which 64% (118 patients) were males, the average age was 49.67 years (SD 13.16) and the average BMI was 28.53 (SD 5.18). The multivariate analysis showed that the risk of having a Visual Analog Scale (VAS) score ≥8 increased when the patient reported standing for more than 6 hours (OR=1.17; P=0.03; CI95%: 1.02-1.359). The risk of a >8-VAS score was higher when the level of ankle dorsiflexion was <0 (OR=1.20; P=0.03; CI95%: 1.02-1.41). Conclusion: Our findings indirectly support the hypothesis that limited ankle dorsiflexion ROM plays a role as a risk factor associated with VAS scores ≥8 in PF patients. Level of Evidence: IV

Introducción: La biotenodesis es la técnica preferida para el manejo de la patología del tendón de la porción larga del bíceps en personas jóvenes, deportistas, trabajadores, y aquellos que desean evitar alguna deformidad estética. El objetivo de nuestro trabajo es evaluar los resultados clínico funcionales, la satisfacción personal del paciente, y las posibles complicaciones de dos técnicas diferentes de tenodesis: Supra-pectoral Artroscopica y Sub-pectoral Abierta Materiales y Métodos: De enero de 2009 a enero de 2012 evaluamos en forma retrospectiva 81 pacientes con patología del tendón largo del biceps tratados con dos técnicas de tenodesis diferentes. Grupo A: 61 pacientes con técnica de biotenodesis artroscópica suprapectoral y Grupo B: 20 pacientes con técnica mini abierta subpectoral utilizando tornillo interferencial. Utilizamos los escores de ASES, Rowe, Simple Shoulder Test, Constant Murley y VAS, y el grado de satisfacción personal en cuanto a estética y dolor local en la cicatriz se evaluo mediante entrevistas personales y telefónicas. El tiempo promedio de seguimiento fue de 12 meses. Resultados: Grupo A: Rowe de 86 puntos, ASES de 81 puntos, el SST de 9 puntos, y Constant Murley de 87 puntos. VAS: escaso dolor post quirúrgico (2/10). El grado de satisfacción fue muy bueno. Grupo B: Rowe de 85 puntos, ASES de 82 puntos, el SST de 8,5 puntos, y el Constant Murley de 85 puntos. VAS: 3/10, mayor en el sitio del abordaje subpectoral. Molestias estéticas sobre la cicatriz en 4 casos, todos estos de sexo femenino. Conclusión: Una tenodesis íntegramente artroscópica es técnicamente mas desafiante y requiere inicialmente una curva de aprendizaje de mayor duración para realizar con éxito este procedimiento. La tenodesis subpectoral es un procedimiento más rápido, sencillo pero su elección estaría únicamente ligada a una cuestión de ahorro de tiempo quirúrgico...

El objetivo de esta revisión sistemática fue establecer si existe alguna relación entre la inestabilidad glenohumeral y cualquier forma de laxitud articular. Se realizó un algoritmo de búsqueda de acuerdo a las guías de PRISMA en las bases de datos de PubMed, OVID, Sport Discus, Scopus y Web of Science usando las palabras clave (Ligament Laxity OR ligamentous Laxity OR generalized joint laxity) AND (shoulder dislocation OR shoulder subluxation OR shoulder luxation OR Shoulder instability) hasta Diciembre de 2013. Se incluyeron los artículos en lengua inglesa que describan algún tipo de relación objetiva, entre inestabilidad glenohumeral y laxitud articular focal o generalizada. Fueron excluidos estudios en cadáveres, o in vitro, o que contengan pacientes con enfermedades del tejido conectivo, reportes de casos, reportes biomecánicos, revisiones, cartas de editores y notas técnicas. La búsqueda arrojó un total de 603 artículos de los cuales 15 cumplían los criterios de inclusión. Según la evidencia encontrada la laxitud articular podría influir en la inestabilidad glenohumeral, pero debido a la gran diversidad de formas en que ambas se relacionan y las diferentes maneras de diagnosticarlas es imposible obtener un análisis estadístico que provea información confiable. Los cirujanos ortopedistas debemos unificar criterios en relación a la definición y a los test para evaluar laxitud articular e inestabilidad glenohumeral y, así de esta manera, poder obtener información más confiable y objetiva. Nivel de Evidencia: IV. Tipo de Estudio: Revisión Sistemática...
The aim of this meta-analisis was to establish whether there is a relationship between any kind of articular laxity and shoulder instability. The search algorithm according to the PRISMA guidelines of PubMed, OVID, Sport Discus, Scopus and Web of Science databases using the keywords (Ligament laxity OR ligamentous laxity OR generalized joint laxity) AND (shoulder dislocation OR shoulder subluxation OR shoulder luxation OR shoulder instability) until December of 2013 was done. Inclusion Criteria: articles in English showing relationship between any types of glenohumeral instability with focal or generalized joint laxity. Studies on cadavers, or in vitro, involving patients with connective tissue diseases, case reports, biomechanical reports, revisions, letters to editors and technical notes were excluded. Fifteen articles of 603 reference of the search were included. Joint laxity may influence shoulder instability. We found diversity not only in how to relate joint laxity and glenohumeral instability buy also different ways of diagnosing. This makes it difficult to obtain statistical analysis that can provide reliable data. Additional efforts aiming to provide consensus are required to clarify this subject. Orthopedics surgeons must unify criteria regarding lax shoulder as well as glenohumeral instability and thus can get more objective and reliable data. Level of Evidence: IV.
