RESUMO

3D printing technology is a tremendously powerful technology to fabricate electrochemical sensing devices. However, current conductive filaments are not aimed at electrochemical applications and therefore require intense activation protocols to unleash a suitable electrochemical performance. Current activation methods based on (electro)chemical activation (using strong alkaline solutions and organic solvents and/or electrochemical treatments) or combined approaches are time-consuming and require hazardous chemicals and dedicated operator intervention. Here, pioneering spark-discharge-activated 3D-printed electrodes were developed and characterized, and it was demonstrated that their electrochemical performance was greatly improved by the effective removal of the thermoplastic support polylactic acid (PLA) as well as the formation of sponge-like and low-dimensional carbon nanostructures. This reagent-free approach consists of a direct, fast, and automatized spark discharge between the 3D-electrode and the respective graphite pencil electrode tip using a high-voltage power supply. Activated electrodes were challenged toward the simultaneous voltammetric determination of dopamine (DP) and serotonin (5-HT) in cell culture media. Spark discharge has been demonstrated as a promising approach for conductive filament activation as it is a fast, green (0.94 GREEnness Metric Approach), and automatized procedure that can be integrated into the 3D printing pipeline.

RESUMO

INTRODUCTION: The established cerebrospinal fluid (CSF) phosphorylated tau181 (p-tau181) may not reliably reflect concomitant Alzheimer's disease (AD) and primary age-related tauopathy (PART) found in Creutzfeldt-Jakob disease (CJD) at autopsy. METHODS: We investigated CSF N-terminal p-tau181, p-tau217, and p-tau231 with in-house Simoa assays in definite CJD (n = 29), AD dementia (n = 75), mild cognitive impairment (MCI) due to AD (n = 65), and subjective cognitive decline (SCD, n = 28). Post-mortem examination performed in patients with CJD 1.3 (0.3-14.3) months after CSF collection revealed no co-pathology in 10, concomitant AD in 8, PART in 8, and other co-pathologies in 3 patients. RESULTS: N-terminal p-tau was increased in CJD versus SCD (p < 0.0001) and correlated with total tau (t-tau) in the presence of AD and PART co-pathology (rho = 0.758-0.952, p ≤ 001). Concentrations in CJD+AD were indistinguishable from AD dementia, with the largest fold-change in p-tau217 (11.6), followed by p-tau231 and p-tau181 (3.2-4.5). DISCUSSION: Variable fold-changes and correlation with t-tau suggest that p-tau closely associates with neurodegeneration and concomitant AD in CJD. HIGHLIGHTS: N-terminal phosphorylated tau (p-tau) biomarkers are increased in Creutzfeldt-Jakob disease (CJD) with and without concomitant AD. P-tau217, p-tau231, and p-tau181 correlate with total tau (t-tau) and increase in the presence of amyloid beta (Aß) co-pathology. N-terminal p-tau181 and p-tau231 in Aß-negative CJD show variation among PRNP genotypes. Compared to mid-region-targeting p-tau181, cerebrospinal fluid (CSF) N-terminal p-tau has greater potential to reflect post-mortem neuropathology in the CJD brain.

RESUMO

La bronquitis plástica es una enfermedad infrecuente y poco estudiada. Se caracteriza por la obstrucción parcial o total de la vía aérea inferior por moldes o yesos gomosos y firmes, compuestos por múltiples sustancias como fibrina, mucina y otros, que se acumulan en la luz bronquial. En la actualidad, no hay un consenso de la fisiopatología real. Puede presentarse con síntomas leves como tos, sibilancias y disnea, hasta eventos fatales de insuficiencia respiratoria. Se clasifican en tipo I (inflamatorios) y tipo II (acelulares). La presencia de la bronquitis plástica es una complicación de varias enfermedades y está relacionada con procedimientos correctivos de cardiopatías congénitas (procedimiento de Fontan). El diagnóstico se hace a través de la identificación de los yesos bronquiales, ya sea cuando el paciente los expectora o por broncoscopía. Se han utilizado múltiples terapias que solo tienen evidencias anecdóticas. En los últimos años se han observado buenos resultados con el uso de heparinas, así como el alteplasa nebulizado e instilado por broncoscopia.


Plastic bronchitis is a rare and little-studied disease. It is characterized by partial or total obstruction of the lower airway by rubbery and firm molds or plasters, made up of multiple substances that accumulate in the bronchial lumen. Currently, there is no consensus on real pathophysiology. It can present itself with mild symptoms such as cough, wheezing and dyspnea, to fatal events of respiratory failure. They are classified into type I (inflammatory) and type II (acellular). The presence of plastic bronchitis is a complication of several diseases and in corrective procedures for congenital heart disease (Fontan procedure). Diagnosis is made by identifying bronchial casts, either by the patient expectorating them or by bronchoscopy. Multiple therapies have been used that only have anecdotal evidence. In recent years, good results have been observed with the use of heparins and tPA nebulized and instilled by bronchoscop.

RESUMO

INTRODUCTION: Leveraging the nonmonolithic structure of Latin America, which represents a large variability in social determinants of health (SDoH) and high levels of genetic admixture, we aim to evaluate the relative contributions of SDoH and genetic ancestry in predicting dementia prevalence in Latin American populations. METHODS: Community-dwelling participants aged 65 and older (N = 3808) from Cuba, Dominican Republic, Mexico, and Peru completed the 10/66 protocol assessments. Dementia was diagnosed using the cross-culturally validated 10/66 algorithm. Multivariate linear regression models adjusted for SDoH were used in the main analysis. This study used cross-sectional data from the 1066 population-based study. RESULTS: Individuals with higher proportions of Native American (>70%) and African American (>70%) ancestry were more likely to exhibit factors contributing to worse SDoH, such as lower educational levels (p < 0.001), lower socioeconomic status (p < 0.001), and higher frequency of vascular risk factors (p < 0.001). After adjusting for measures of SDoH, there was no association between ancestry proportion and dementia probability, and ancestry proportions no longer significantly accounted for the variance in cognitive performance (African predominant p = 0.31 [-0.19, 0.59] and Native predominant p = 0.74 [-0.24, 0.33]). DISCUSSION: The findings suggest that social and environmental factors play a more crucial role than genetic ancestry in predicting dementia prevalence in Latin American populations. This underscores the need for public health strategies and policies that address these social determinants to effectively reduce dementia risk in these communities. HIGHLIGHTS: Countries in Latin America express a large variability in social determinants of health and levels of admixture. After adjustment for downstream societal factors linked to SDoH, genetic ancestry shows no link to dementia. Population ancestry profiles alone do not influence cognitive performance. SDoH are key drivers of racial disparities in dementia and cognitive performance.

RESUMO

INTRODUCION: The concept of a window of opportunity in hidradenitis suppurativa (HS) management suggests that early initiation of biological therapy leads to better outcomes, though its timing remains uncertain. METHODS: We conducted a retrospective observational multicenter study, including consecutive patients with moderate to severe HS who initiated secukinumab treatment following prior failure with systemic antibiotics or adalimumab. Therapeutic burden was defined as the sum of previous systemic treatment cycles and previous major surgical interventions for HS. Patients were followed up for 24 weeks. Main outcomes were safety and effectiveness, assessed through the proportion of patients achieving HS Clinical Response (HiSCR) and a 55% reduction in International HS Severity Score System (IHS4-55). Additionally, potential predictors of response to secukinumab were studied. Analysis was performed on an intention-to-treat basis. RESULTS: A total of 67 patients (33 men, 34 women) were included, with a mean age of 41.55 (11.94) years and a mean baseline IHS4 of 17.88 (11.13). The mean therapeutic burden was 6.06 (3.49). At week 24, 10.45% (7/67) of patients experienced adverse events, with three leading to treatment discontinuation. At week 24, 41.79% (28/67) of patients achieved HiSCR, and 44.78% (30/67) of patients achieved IHS4-55. HiSCR could not be calculated in 12 patients with a baseline AN count < 3. A lower therapeutic burden was significantly associated with a higher likelihood of achieving HiSCR and IHS4-55 at week 24. CONCLUSIONS: Secukinumab showed safety and efficacy in real-world patients with HS, and the inverse correlation found between therapeutic burden and treatment response supports the concept of a window of opportunity, offering insights into its timing.

RESUMO

OBJECTIVES: We report the safety, tolerability and efficacy of tofacitinib in patients with juvenile idiopathic arthritis (JIA) in an ongoing long-term extension (LTE) study. METHODS: Patients (2-<18 years) with JIA who completed phase 1/3 index studies or discontinued for reasons excluding treatment-related serious adverse events (AEs) entered the LTE study and received tofacitinib 5 mg two times per day or equivalent weight-based doses. Safety outcomes included AEs, serious AEs and AEs of special interest. Efficacy outcomes included improvement since tofacitinib initiation per the JIA-American College of Rheumatology (ACR)70/90 criteria, JIA flare rate and disease activity measured by Juvenile Arthritis Disease Activity Score (JADAS)27, with inactive disease corresponding to JADAS ≤1.0. RESULTS: Of 225 patients with JIA (median (range) duration of treatment, 41.6 (1-103) months), 201 (89.3%) had AEs; 34 (15.1%) had serious AEs. 10 patients developed serious infections; three had herpes zoster. Two patients newly developed uveitis. Among patients with polyarticular course JIA, JIA-ACR70/90 response rates were 60.0% (78 of 130) and 33.6% (47 of 140), respectively, at month 1, and generally improved over time. JIA flare events generally occurred in <5% of patients through to month 48. Observed mean (SE) JADAS27 was 22.0 (0.6) at baseline, 6.2 (0.7) at month 1 and 2.8 (0.5) at month 48, with inactive disease in 28.8% (36 of 125) of patients at month 1 and 46.8% (29 of 82) at month 48. CONCLUSIONS: In this interim analysis of LTE study data in patients with JIA, safety findings were consistent with the known profile of tofacitinib, and efficacy was maintained up to month 48. TRIAL REGISTRATION NUMBER: NCT01500551.

RESUMO

BACKGROUND: Although tDCS constitutes a non-invasive neuromodulation technique with promising results in a great variety of applications, its clinical implementation is compromised by the high inter-subject variability reported. This study aims to analyze the inter-subject variability in electric fields (E-fields) over regions of the cortical motor network under two electrode montages: the classical C3Fp2 and an alternative P3F3, which confines more the Efield over this region. Methods: Computational models of the head of 98 healthy subjects were developed to simulate the E-field under both montages. E-field parameters such as magnitude, focality and orientation were calculated over three regions of interest (ROI): M1S1, SMA and preSMA. The role of anatomical characteristics as a source of inter-subject variability on E-field parameters was addressed using linear mixed-effect models. Results: P3F3 showed a more confined E-field distribution over M1S1 than C3Fp2; the latter elicited higher E-fields over supplementary motor areas. Both montages showed high inter-subject variability, especially for the normal component over C3Fp2. Skin, bone and CSF ROI volumes showed a negative association with E-field magnitude irrespective of montage. Grey matter volume and montage were the main sources of variability for focality. The curvature of gyri was found to be significantly associated with the variability of normal E-fields. Conclusions: Computational modelling proves useful in the assessment of E-field variability. Our simulations predict significant differences in E-field magnitude and focality for C3Fp2 and P3F3. However, anatomical characteristics were also found to be significant sources of E-field variability irrespective of electrode montage. .

RESUMO

Background: Paragangliomas (PGL) are rare neuroendocrine tumors derived from the autonomic nervous system paraganglia. Urinary bladder paragangliomas (UBPGL) originate from the sympathetic neurons of the urinary bladder wall and represent 0.7% of all paragangliomas and <0.05% of all bladder tumors. PGL and UBPGL can be associated with SDHB, SDHD, NF1, and VHL gene variants, with the most common germline alterations found in SDHB and VHL. Case report: We report a case of a 42-year-old woman who presented with menorrhagia/hematuria, uterine leiomyomas, as well as cardiac and bladder masses. The cardiac mass was favored to be a myxoma based on clinical findings, while the bladder mass was diagnosed as UBPGL. A novel SDHB mutation (c.642G>A, p Q214Q), detected in the UBPGL, was proven to be somatic. Although this variant was seemingly synonymous, it was predicted to have a loss of function due to the splice site effect, which was further supported by the immunohistochemical loss of SDHB. Conclusion: This case highlights the challenges of diagnosing an extremely rare entity, bladder paraganglioma, with an emphasis on the multidisciplinary approach to navigate various clinical and imaging findings that may initially be misleading. In addition, a novel loss of function SDHB variant that could have been overlooked as a synonymous variant is herein reported, while also illustrating the importance of both germline and somatic mutation testing.

RESUMO

OBJECTIVES: identifying host response biomarkers implicated in the emergence of organ failure during infection is key to improving early detection of this complication. METHODS: twenty biomarkers of innate immunity, T-cell response, endothelial dysfunction, coagulation and immunosuppression were profiled in 180 surgical patients with infections of diverse severity (IDS) and 53 with no infection (nIDS). Those better differentiating IDS/nIDS in the area under the curve (AUC) were combined to test their association with the Sequential Organ Failure Assessment (SOFA) score by linear regression analysis in IDS. Results were validated in another IDS cohort of 174 patients. RESULTS: C-reactive protein, procalcitonin, pentraxin-3, lipocalin-2, TNF-α, angiopoietin-2, TREM-1 and IL-15 yielded AUCs ≥ 0.75 to differentiate IDS from nIDS. The combination of lipocalin-2, IL-15, TREM-1, angiopoietin-2 (Dys-4) showed the strongest association with SOFA in IDS (adjusted regression coefficient; standard error; p): Dys-4 (3.55;0.44; <0.001), Lipocalin-2 (2.24; 0.28; <0.001), angiopoietin-2 (1.92; 0.33; <0.001), IL-15 (1.78; 0.40; <0.001), TREM-1(1.74; 0.46; <0.001), TNF-α (1.60; 0.31; <0.001), pentraxin-3 (1.12; 0.18; <0.001), procalcitonin (0.85; 0.12; <0.001). Dys-4 provided similar results in the validation cohort. CONCLUSIONS: there is a synergistic impact of innate immunity hyper-activation (lipocalin-2, IL-15, TREM-1) and endothelial dysfunction (angiopoietin-2) on the magnitude of organ failure during infection.

RESUMO

BACKGROUND: Several antithrombotic treatments during emergent carotid artery stenting (eCAS) have been proposed, but an appropriate protocol to balance risk-benefit is not well known. OBJECTIVE: To investigate the efficacy and safety of tirofiban compared with aspirin in patients with acute ischemic stroke undergoing eCAS. METHODS: We conducted a retrospective single-center study of the prospective ARTISTA Registry, including patients with atherosclerotic internal carotid artery occlusion treated with eCAS. Two groups, according to antiplatelet drug, were studied: aspirin (250-500 mg single-dose) versus tirofiban (500 µg bolus+200 µg/h). Primary outcomes were the rate of in-stent thrombosis and symptomatic intracranial hemorrhage (sICH) within the first 24 hours. RESULTS: During the period 2019-2023, 181 patients were included, 103 received aspirin, 78 tirofiban; 149 (82.3%) had tandem lesions. The primary efficacy outcome occurred in 9 (9.4%) in the aspirin group, as compared with 1 (1.3%) in the tirofiban group (adjusted odds ratio (aOR)=0.11, 95% CI 0.01 to 0.98; P=0.048). The primary safety outcome was detected in 12 (11.7%) in the aspirin group, as compared with 2 (2.6%) in the tirofiban group (aOR=0.16, 95% CI 0.03 to 0.87; P=0.034). The tirofiban group presented a lower risk of parenchymal hemorrhage (18 (17.4%) vs 4 (5.2%), aOR=0.27, 95% CI 0.09 to 0.88; P=0.029) and an increased rate of excellent recanalization (expanded Treatment in Cerebral Infarction (eTICI) 2c-3) (50 (48.5%) vs 54 (69.2%); aOR=2.15, 95% CI 1.12 to 4.13; P=0.02). There were no differences in functional outcomes or mortality at 3 months. CONCLUSIONS: Periprocedural antithrombotic therapy with tirofiban was associated with a lower risk of in-stent thrombosis and sICH at 24 hours from eCAS compared with aspirin. Prospective randomized clinical trials are needed to confirm our results.

RESUMO

BACKGROUND: Cognitive behavioral therapy for insomnia (CBT-I) is the gold-standard treatment for insomnia disorder in adults. Compared to young adults, older adults have increased risk for the development of conditions associated with chronic pain, which may impact the efficacy of CBT-I in improving insomnia symptoms in older adults. This study evaluated the effect of participant-rated pain on sleep-related outcomes of a supervised, non-clinician administered CBT-I program in older adult patients with chronic insomnia disorder. METHODS: Secondary analysis was conducted using data from a randomized controlled trial among 106 community-dwelling older adult veterans (N = 106; mean age 72.1 years, 96% male, 78.3% White, 6.6% Hispanic, 5.7% African American) with chronic (≥3 months) insomnia disorder. Participants engaged in five sessions of manual-based CBT-I in individual or group format within one Department of Veterans Affairs healthcare system, provided by non-clinician "sleep coaches" who had weekly telephone supervision by behavioral sleep medicine specialists. Insomnia symptoms (Insomnia Severity Index), perceived sleep quality (Pittsburgh Sleep Quality Index), fatigue (Flinder's Fatigue Scale), daytime sleepiness (Epworth Sleepiness Scale), and perceived pain severity (items from the Geriatric Pain Measure) were assessed at 4 time points: baseline, one-week posttreatment, 6-month follow-up, and 12-month follow-up. Mixed effects models with time invariant and time varying predictors were employed for analyses. RESULTS: CBT-I improved insomnia symptoms, perceived sleep quality, fatigue, and daytime sleepiness among older veterans with chronic insomnia. Participant-reported pain was associated with greater improvements in insomnia symptoms following CBT-I. Pain did not affect improvements in other sleep-related outcomes (-0.38 ≤ b ≤ 0.07, p > 0.05). Between-subjects differences in pain, but not within-subject changes in pain over time, appeared to play a central role in insomnia symptom improvement at posttreatment, with individuals with higher-than-average pain showing greater insomnia symptom improvement (ISI score reduction; -0.32 ≤ b ≤ -0.28, p ≤ 0.005). CONCLUSIONS: Pain did not meaningfully hinder the effects of CBT-I on sleep outcomes. Among older veterans with chronic insomnia disorder, individuals with higher pain exhibited slightly greater improvement in insomnia than those with lower levels of pain. These findings suggest that experiencing pain does not impair treatment response and should not preclude older adults with insomnia from being offered CBT-I.

RESUMO

The incidence of Candida infections has increased in the last decade, posing a serious threat to public health. Appropriately facing this challenge requires precise epidemiological data on species and antimicrobial resistance incidence, but many countries lack appropriate surveillance programs. This study aims to bridge this gap for Morocco by identifying and phenotyping a year-long collection of clinical isolates (n = 93) from four clinics in Tetouan. We compared the current standard in species identification with molecular methods and assessed susceptibility to fluconazole and anidulafungin. Our results identified limitations in currently used diagnostics approaches, and revealed that C. albicans ranks as the most prevalent species with 60 strains (64.52%), followed by C. glabrata with 14 (15.05%), C. parapsilosis with 6 (6.45%), and C. tropicalis with 4 (4.30%). In addition, we report the first identification of C. metapsilosis in Morocco. Susceptibility results for fluconazole revealed that some isolates were approaching MICs resistance breakpoints in C. albicans (2), and C. glabrata (1). Our study also identified anidulafungin resistant strains in C. albicans (1), C. tropicalis (1), and C. krusei (2), rendering the two strains from the latter species multidrug-resistant due to their innate resistance to fluconazole. These results raise concerns about species identification and antifungal resistance in Morocco and highlight the urgent need for more accurate methods and preventive strategies to combat fungal infections in the country.

RESUMO

Granuloviruses (GVs) Betabaculovirus associated with the fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), especially those of the type I, have scarcely been studied. These GVs might be an effective alternative for the biocontrol of this insect. In this study, the native GVs SfGV-CH13 and SfGV-CH28 were isolated from FAW larvae and characterized for morphology, molecular traits, and insecticidal activity. The elapsed time between symptomatic infection of larvae and stop feeding as well as the weight of larvae before death or prior to pupation were also evaluated. Both GVs had ovoid shape and a length of 0.4 µm. They had the same DNA restriction profiles and their genome sizes were about 126 kb. The symptomatic infection with the tested GVs mainly caused flaccidity of larva body and discoloration of integument. The integument lysis was only observed in 8% of infected larvae. Infected larvae gradually stopped feeding. Overall, these symptoms are characteristic of infections caused by type I GVs, which are known as monoorganotropic or slow-killing GVs. The median lethal dose (LD50) values for SfGV-CH13 and SfGV-CH28 isolates were 5.4 × 102 and 1.1 × 103 OBs/larva, respectively. The median lethal time (LT50) ranged from 17 to 24 days. LT50 values decreased as the viral dose was increased. The elapsed time from symptomatic infection until pupation and body weight of larvae (third instar) were higher with SfGV-CH28 than SfGV-CH13. Both granulovirus isolates were able to kill the FAW larvae from the 12th day.

RESUMO

Objective: To identify the incidence of in-hospital major adverse cardiac events (MACE) with the use of mechanic thromboaspiration plus IIb/IIIa glycoprotein inhibitors versus only use of IIb/IIIa glycoprotein inhibitors on patients with acute ST elevation myocardial infarction. Method: Retrospective, observational, cohort analytic study, on patients with acute ST elevation myocardial infarction that had angiography thrombus TIMI 5 grade, treated between October 2021 and December 2022. Results: A total of 237 patients were included. In 113 patients thromboaspiration were used, 124 patients didn't used. 81.6% were men. In-hospital MACE occurred on 31.9% of patients with thromboaspiration use vs. 30.6% on patients with no use (RR: 1.05; IC95%: 0.61-1.93; p = 0.840). Incidence of malignant arrhythmias were of 8% with thromboaspiration use vs. 1.6% on patients with no use (RR: 5.27; IC95%: 1.11-24.97; p = 0.020). Conclusions: The use of thromboaspiration on concomitant treatment with IIb/IIIa glycoprotein inhibitors was similar with only IIb/IIIa glycoprotein inhibitors in reducing incidence of in-hospital MACE on patients with ST elevation acute myocardial infarction and high thrombus burden. The study has several limitations, so results should be taken with caution.


Objetivo: Identificar la incidencia de eventos cardiovasculares adversos mayores (ECAM) intrahospitalarios con el uso de tromboaspiración mecánica más inhibidores de la glucoproteína IIb/IIIa contra solo inhibidores de la glucoproteína IIb/IIIa en pacientes con infarto agudo al miocardio con elevación del segmento ST (IAMCEST). Método: Estudio retrospectivo, observacional, analítico, de cohorte, en pacientes con IAMCEST con trombo angiográfico de grado TIMI 5, tratados entre octubre de 2021 y diciembre de 2022. Resultados: Cumplieron los criterios de inclusión 237 pacientes. En 113 se usó tromboaspirador más inhibidores IIb/IIIa y en 124 solo inhibidores IIb/IIIa. El 81.6% fueron hombres. La incidencia de ECAM intrahospitalarios fue del 31.9% en los pacientes con tromboaspiración y del 30.6% en los pacientes con solo inhibidores IIb/IIIa (RR: 1.05; IC95%: 0.61-1.93; p = 0.840). La incidencia de arritmias graves fue del 8% en los pacientes con tromboaspiración y del 1.6% en los pacientes con solo inhibidores IIb/IIIa (RR: 5.27; IC95%: 1.11-24.97; p = 0.020). Conclusiones: La frecuencia de ECAM asociados al uso de tromboaspiración mecánica como coadyuvante a los inhibidores de la glucoproteína IIb/IIIa en pacientes con IAMCEST y trombo angiográfico de grado TIMI 5 no es diferente de la de aquellos pacientes en las que solo se utilizan inhibidores de la glucoproteína IIb/IIa. El estudio tiene varias limitaciones, por lo que los resultados deben tomarse con cautela.

RESUMO

PURPOSE: To provide an overview of the outcomes of the use of autogenous platelet concentrates in immediate implant placement. MATERIALS AND METHODS: Based on an a priori protocol, a systematic search was performed of the National Library of Medicine (MEDLINE via PubMed), Embase and Scopus databases. Randomised and non-randomised controlled clinical trials on immediate implant placement including at least one study arm with use of platelet-rich fibrin or platelet-rich plasma as a gap filler between immediately placed implants and the alveolar bone were included. A random-effects meta-analysis model was built to assess the primary outcomes of marginal bone loss and probing pocket depths between test (platelet concentrates) and control (no graft or other graft materials) groups. A risk of bias assessment was performed and the Grading of Recommendations Assessment, Development and Evaluation approach was used to assess the certainty of evidence. RESULTS: A total of 20 trials (595 immediate implants placed in 454 individuals) were included in the meta-analytic model. Based on the data from studies with a minimum post-prosthetic loading period of 6 months after immediate implant placement, overall, the application of platelet concentrates was associated with significantly lower marginal bone loss and probing pocket depth compared to the control groups (mean difference -0.36 mm; P < 0.01 and mean difference -0.47 mm; P < 0.01, respectively). No additional benefit of application of platelet concentrates was detected regarding primary stability of immediate implants. Subgroup analysis revealed significantly lower marginal bone loss with xenogeneic bone alone compared to platelet concentrates alone as grafting material in immediate implant placement (mean difference 0.66 mm; P < 0.01). Evidence on soft tissue outcomes and aesthetic parameters was scarce. CONCLUSIONS: A low level of certainty based on the Grading of Recommendations Assessment, Development and Evaluation approach indicates superior outcomes in terms of marginal bone loss and probing pocket depth in immediate implant placement with the use of platelet concentrates versus no graft. Future research should be tailored towards a standardised protocol for preparation of platelet concentrates and inclusion of soft tissue and aesthetic outcomes as well.

RESUMO

Single tooth orange discoloration secondary to root canal calcification occurs as a consequence of dental trauma, orthodontic treatment, or for unknown rea- sons. A correct case history must be compiled and a CBCT study carried out in order to establish the diag- nosis and define the best treatment plan in each case. The aim of the present study was to offer a therapeutic protocol involving a clinical decision-making tree dia- gram based on the presence or absence of apical dis- ease and the degree of canal calcification. Dental bleaching and the use of ceramic veneers allow es- thetic restoration in such cases.

RESUMO

BACKGROUND: Alzheimer's disease (AD) is characterized by the accumulation of amyloid-ß (Aß) plaques, neurofibrillary tau tangles, and neurodegeneration in the brain parenchyma. Here, we aimed to (i) assess differences in blood and imaging biomarkers used to evaluate neurodegeneration among cognitively unimpaired APOE ε4 homozygotes, heterozygotes, and non-carriers with varying risk for sporadic AD, and (ii) to determine how different cerebral pathologies (i.e., Aß deposition, medial temporal atrophy, and cerebrovascular pathology) contribute to blood biomarker concentrations in this sample. METHODS: Sixty APOE ε4 homozygotes (n = 19), heterozygotes (n = 21), and non-carriers (n = 20) ranging from 60 to 75 years, were recruited in collaboration with Auria biobank (Turku, Finland). Participants underwent Aß-PET ([11C]PiB), structural brain MRI including T1-weighted and T2-FLAIR sequences, and blood sampling for measuring serum neurofilament light chain (NfL), plasma total tau (t-tau), plasma N-terminal tau fragments (NTA-tau) and plasma glial fibrillary acidic protein (GFAP). [11C]PiB standardized uptake value ratio was calculated for regions typical for Aß accumulation in AD. MRI images were analysed for regional volumes, atrophy scores, and volumes of white matter hyperintensities. Differences in biomarker levels and associations between blood and imaging biomarkers were tested using uni- and multivariable linear models (unadjusted and adjusted for age and sex). RESULTS: Serum NfL concentration was increased in APOE ε4 homozygotes compared with non-carriers (mean 21.4 pg/ml (SD 9.5) vs. 15.5 pg/ml (3.8), p = 0.013), whereas other blood biomarkers did not differ between the groups (p > 0.077 for all). From imaging biomarkers, hippocampal volume was significantly decreased in APOE ε4 homozygotes compared with non-carriers (6.71 ml (0.86) vs. 7.2 ml (0.7), p = 0.029). In the whole sample, blood biomarker levels were differently predicted by the three measured cerebral pathologies; serum NfL concentration was associated with cerebrovascular pathology and medial temporal atrophy, while plasma NTA-tau associated with medial temporal atrophy. Plasma GFAP showed significant association with both medial temporal atrophy and Aß pathology. Plasma t-tau concentration did not associate with any of the measured pathologies. CONCLUSIONS: Only increased serum NfL concentrations and decreased hippocampal volume was observed in cognitively unimpaired APOEε4 homozygotes compared to non-carriers. In the whole population the concentrations of blood biomarkers were affected in distinct ways by different pathologies.

RESUMO

Systematic reviews and meta-analysis evaluating the prevalence, incidence, and psychological comorbidities of psoriatic arthritis (PsA) are increasing, so it's time to perform an overview of systematic reviews. To summarize the pooled prevalence, incidence, and psychological comorbidities rates of PsA, and to explore possible continent disparities. In this overview of systematic reviews the CINAHL, EMBASE, PsycINFO, and PubMed were searched to October 25, 2023. This overview included systematic reviews with meta-analysis of people with PsA, providing the pooled prevalence or incidence rates of PsA in general, or clinical populations and/or psychological comorbidities. The Preferred Reporting Items for Overviews of Reviews (PRIOR) statement was followed. AMSTAR-2 assessed the quality of reviews. The degree of overlap was calculated using the corrected covered area (CCA). Maps were developed using the location of where primary studies were conducted using DataWrapper App. The protocol was prospectively registered with Open Science Framework registry. Pooled prevalence and incidence rates of PsA or its associated psychological comorbidities in general or specific populations. We also collected locations from the primary studies of the included meta-analyses. Only the assessment of prevalence rates of PsA in people with psoriasis showed slight overlap (CCA = 3.3%). Items 2, 3, 4, 7, 8, 10, 12, and 13 were poorly reported in AMSTAR-2. The pooled prevalence of PsA ranged from 0.13 to 0.15% in the general population, and 15.5% to 19.7% in people with psoriasis. The pooled incidence of PsA ranged from 8.26 to 9.27 cases per 100,000 inhabitants to 0.87 cases in individuals with hidradenitis suppurativa. The pooled prevalence of psychological comorbidities was 11.9-20% for depression, 19-33% anxiety, 38% alexithymia, and 72.9% in poor sleep quality. Only the pooled incidence of depression was assessed with 21.3 per 1000-person year. PsA seems to be prevalent and incident not only in people with psoriasis, but also in general population. Depression and anxiety symptoms may be present in some patients with PsA. Finally, continent disparities exist, and methodological and clinical issues were found, which could be helpful in the future agenda of the epidemiology of PsA.

RESUMO

This study presents a pioneering approach that leverages advanced sensing technologies and data processing techniques to enhance the process of clinical documentation generation during medical consultations. By employing sophisticated sensors to capture and interpret various cues such as speech patterns, intonations, or pauses, the system aims to accurately perceive and understand patient-doctor interactions in real time. This sensing capability allows for the automation of transcription and summarization tasks, facilitating the creation of concise and informative clinical documents. Through the integration of automatic speech recognition sensors, spoken dialogue is seamlessly converted into text, enabling efficient data capture. Additionally, deep models such as Transformer models are utilized to extract and analyze crucial information from the dialogue, ensuring that the generated summaries encapsulate the essence of the consultations accurately. Despite encountering challenges during development, experimentation with these sensing technologies has yielded promising results. The system achieved a maximum ROUGE-1 metric score of 0.57, demonstrating its effectiveness in summarizing complex medical discussions. This sensor-based approach aims to alleviate the administrative burden on healthcare professionals by automating documentation tasks and safeguarding important patient information. Ultimately, by enhancing the efficiency and reliability of clinical documentation, this innovative method contributes to improving overall healthcare outcomes.

RESUMO

BACKGROUND: Performing cardiovascular and cancer screenings in target populations can reduce mortality. Visiting a General Practitioner (GP) once a year is related to an increased likelihood of preventive care. The aim of this study was to analyse the influence of visiting a GP in the last year on the delivery of preventive services based on sex and household income. METHODS: Cross-sectional study using data collected from the European Health Interview Survey 2013-2015 of individuals aged 40-74 years from 29 European countries. The variables included: sociodemographic factors (age, sex, and household income (HHI) quintiles [HHI 1: lowest income, HHI 5: more affluent]), lifestyle factors, comorbidities, and preventive care services (cardiometabolic, influenza vaccination, and cancer screening). Descriptive statistics, bivariate analyses and multilevel models (level 1: citizen, level 2: country) were performed. RESULTS: 242,212 subjects were included, 53.7% were female. The proportion of subjects who received any cardiometabolic screening (92.4%) was greater than cancer screening (colorectal cancer: 44.1%, gynaecologic cancer: 40.0%) and influenza vaccination. Individuals who visited a GP in the last year were more prone to receive preventive care services (cardiometabolic screening: adjusted OR (aOR): 7.78, 95% CI: 7.43-8.15; colorectal screening aOR: 1.87, 95% CI: 1.80-1.95; mammography aOR: 1.76, 95% CI: 1.69-1.83 and Pap smear test: aOR: 1.89, 95% CI:1.85-1.94). Among those who visited a GP in the last year, the highest ratios of cardiometabolic screening and cancer screening benefited those who were more affluent. Women underwent more blood pressure measurements than men regardless of the HHI. Men were more likely to undergo influenza vaccination than women regardless of the HHI. The highest differences between countries were observed for influenza vaccination, with a median odds ratio (MOR) of 6.36 (under 65 years with comorbidities) and 4.30 (over 65 years with comorbidities), followed by colorectal cancer screening with an MOR of 2.26. CONCLUSIONS: Greater adherence to preventive services was linked to individuals who had visited a GP at least once in the past year. Disparities were evident among those with lower household incomes who visited a GP. The most significant variability among countries was observed in influenza vaccination and colorectal cancer screening.
