RESUMO

Despite uncertainty about the specific molecular mechanisms driving major depressive disorder (MDD), the Wnt signaling pathway stands out as a potentially influential factor in the pathogenesis of MDD. Known for its role in intercellular communication, cell proliferation, and fate, Wnt signaling has been implicated in diverse biological phenomena associated with MDD, spanning neurodevelopmental to neurodegenerative processes. In this systematic review, we summarize the functional differences in protein and gene expression of the Wnt signaling pathway, and targeted genetic association studies, to provide an integrated synthesis of available human data examining Wnt signaling in MDD. Thirty-three studies evaluating protein expression (n = 15), gene expression (n = 9), or genetic associations (n = 9) were included. Only fifteen demonstrated a consistently low overall risk of bias in selection, comparability, and exposure. We found conflicting observations of limited and distinct Wnt signaling components across diverse tissue sources. These data do not demonstrate involvement of Wnt signaling dysregulation in MDD. Given the well-established role of Wnt signaling in antidepressant response, we propose that a more targeted and functional assessment of Wnt signaling is needed to understand its role in depression pathophysiology. Future studies should include more components, assess multiple tissues concurrently, and follow a standardized approach.

RESUMO

BACKGROUND: Chronic venous disease is a frequent and prevalent pathology. Its surgical treatment has been shown to be cost-effective. Thermal endoablation performed as major outpatient surgery (MAS) is the technique of choice. OBJECTIVE: To know the satisfaction of patients after MAS and the quality of care provided. METHOD: Observational, descriptive, cross-sectional study, carried out between January 2019 and March 2020. A survey was carried out on patients who underwent endovascular radiofrequency thermoablation in two hospitals in Spain, consisting of two questionnaires: one ad hoc and one another of satisfaction (SERCAL). Quality indices for MAS were measured. RESULTS: We analyzed 156 episodes. 145 interventions were carried out. We found 4 (2.8%) unscheduled admissions. 3 patients (2.1%) attended the emergency department. There was a 99.3% success rate. 100% of the patients had pre-surgical recommendations and informed consent. We obtained 48 surveys (response rate: 33.1%). All the patients gave a rating greater ≥ 8 in quality of care (x = 9.83) and would recommend this procedure to their relatives (x = 9.71). CONCLUSIONS: Endovascular radiofrequency thermoablation performed in MAS has a high success rate and a very low rate of admission and visit to the emergency room. Patient satisfaction is high.


ANTECEDENTES: La enfermedad venosa crónica es una patología frecuente y prevalente. Su tratamiento quirúrgico ha mostrado ser coste-efectivo. La endoablación térmica realizada como cirugía mayor ambulatoria (CMA) es la técnica de elección. OBJETIVO: Conocer la satisfacción de los pacientes tras CMA y la calidad de la atención brindada. MÉTODO: Estudio observacional, descriptivo y transversal, realizado entre enero de 2019 y marzo de 2020. Se realizó una encuesta a los pacientes intervenidos mediante termoablación endovascular por radiofrecuencia en dos hospitales de España, con dos cuestionarios: uno ad hoc y otro de satisfacción (SERCAL). Se midieron índices de calidad para CMA. RESULTADOS: Analizamos 156 episodios. Se realizaron 145 intervenciones. Encontramos 4 (2.8%) ingresos no programados. Tres pacientes (2.1%) acudieron a urgencias. Hubo una tasa de éxito del 99.3%. El 100% de los pacientes contaban con recomendaciones prequirúrgicas y consentimiento informado. Obtuvimos 48 encuestas (índice de respuesta: 33.1%). Todos los pacientes otorgaron una calificación ≥ 8 en calidad de atención (x = 9.83) y recomendarían este procedimiento a sus familiares (x = 9.71). CONCLUSIONES: La termoablación endovascular por radiofrecuencia realizada en CMA tiene una alta tasa de éxito y unas tasas de ingreso y visita a urgencias muy bajas. La satisfacción de los pacientes es elevada.

RESUMO

Model organisms are fundamental in cancer research given that they rise the possibility to characterize in a quantitative-objective fashion the organisms as a whole in ways that are infeasible in humans. From this perspective, model organisms with short generation times and established protocols for genetic manipulation allow the understanding of basic biology principles that might guide carcinogenic onset. The cancer-hallmarks (CHs) approach, a modular perspective for cancer understanding, stands that underlying the variability among different cancer types, critical events support the carcinogenic origin and progression. Thus, CHs as interconnected genetic circuitry, have a causal effect over cancer biogenesis and might represent a comparison scaffold among model organisms to identify and characterize evolutionarily conserved modules to understand cancer. Nevertheless, the identification of novel cancer regulators by comparative genomics approaches relies on selecting specific biological processes or related signaling cascades that limit the type of detected regulators, even more, holistic analysis from a systemic perspective is absent. Similarly, although the plant Arabidopsis thaliana has been used as a model organism to dissect specific disease-associated mechanisms, given the evolutionary distance between plants and humans, a general concern about the utility of using A. thaliana as a cancer model persists. In the present research, we take advantage of the CHs paradigm as a framework to establish a functional systemic comparison between plants and humans, that allowed the identification not only of specific novel key genetic regulators, but also, biological processes, metabolic systems, and genetic modules that might contribute to the neoplastic transformation. We propose five cancer-hallmarks that overlapped in conserved mechanisms and processes between Arabidopsis and human and thus, represent mechanisms which study can be prioritized in A. thaliana as an alternative model for cancer research. Additionally, derived from network analyses and machine learning strategies, a new set of potential candidate genes that might contribute to neoplastic transformation is described. These findings postulate A. thaliana as a suitable model to dissect, not all, but specific cancer properties, highlighting the importance of using alternative complementary models to understand carcinogenesis.

RESUMO

BACKGROUND: Major Depressive Disorder (MDD) and obesity are bidirectionally related, but the amount of weight-gain secondary to MDD is unknown. We aimed to estimate the adjusted effect of MDD on weight-change in prospective studies compared to individuals without MDD. METHODS: Scopus/MEDLINE, PsycInfo, Web of Science and Cochrane were systematically searched for prospective observational studies of participants with a diagnosis of MDD. We included studies that conducted regression analyses on weight-variables. We searched for weight-variables reported at baseline, follow-up, and regression analyses. A meta-analysis of the odds ratios reported in logistic regression models was performed using the generic inverse weight variance method. RESULTS: Eight studies were included with a total of 60,443 subjects; 56.8 % with MDD. Weight-variables included weight, BMI, waist circumference, fat mass, and obesity incidence. In three follow-up reports, weight-variables increased more in participants with MDD and its subphenotypes than in control subjects, except for one MDD subphenotype. Meta-analysis of three eligible studies (n = 21,935) showed a significantly greater likelihood of incident obesity in participants with MDD (OR:1.48, 95%CI 1.03-2.13). MDD subphenotype reports might suggest a greater risk for atypical MDD. LIMITATIONS: Heterogeneity in weight related variables, follow-ups, and regression models; scarcity of follow-up data; and limited studies eligible for meta-analysis. CONCLUSIONS: Despite previous associations between MDD and obesity, current prospective evidence on MDD related weight-change is scarce and heterogeneous. Our findings suggest a need to standardize weight-change assessment in MDD trials. Moreover, careful weight tracking and management should be incorporated in clinical settings.

RESUMO

INTRODUCTION: Synovial Sarcoma is a rare malignancy that accounts between 8 and 10% of soft tissue neoplasms, with the highest presentation rate in extremities, an extremely uncommon condition in head and neck. CLINICAL FINDINGS: We present a case of an 18-year-old male with synovial sarcoma situated at hypopharynx who underwent surgical resection and postoperative radiotherapy. CONCLUSION: Synovial Sarcoma represents a rare head and neck malignancy with challenging diagnostic approach due to its frequency and nonspecific clinical manifestations. Surgical treatment must assure good free margins. Adjuvant radiotherapy has a positive impact in local recurrence and survival.

RESUMO

In Chile, the Immunization Department of the Ministry of Health has carried out the seasonal influenza vaccination campaign annually since 1982 in collaboration with the national health services, regional health offices, and primary health care centres. With the aim of preventing deaths and serious morbidity in high-risk groups and preserving the integrity of health services, the seasonal influenza campaign had been the largest implemented in Chile until 2020, since in 2021 the vaccination campaign against SARS-CoV-2 is expected to become the largest ever implemented. In response to local demographic and epidemiological changes, and taking into account the new scientific evidence on the safety and immunogenicity of vaccines, the influenza vaccines available in Chile would increase annually as a result of campaign planning. In 2020, the influenza campaign had to be re-planned while in progress due to the addition of new high-risk groups to be vaccinated in accordance with the SARS-CoV-2 pandemic health alert modification of March 6th, 2020. Over the course of three weeks, the Immunization Department managed to increase the doses of available influenza vaccines from 6,799,800 previously agreed upon to 8,480,325 and thus serve high-risk groups, guaranteeing their access to state funded influenza vaccination.

RESUMO

Resumen Desde 1982, cada año el Departamento de Inmunizaciones del Ministerio de Salud de Chile lleva a cabo la campaña de vacunación contra influenza junto con las Secretarías Regionales Ministeriales-SEREMI, Servicios de Salud y centros de atención primaria de salud. Con los objetivos de prevenir mortalidad y morbilidad grave en grupos de mayor riesgo y de preservar la integridad de los servicios de salud, hasta el 2020 las campañas de vacunación contra influenza serían las más grandes implementadas en Chile, para dar paso, el 2021, a la vacunación contra SARS-CoV-2. Obedeciendo a cambios demográficos y epidemiológicos locales y acogiendo los avances científicos sobre seguridad e inmunogenicidad de la vacuna, el incremento de las vacunas influenza disponibles en Chile forma parte de la planificación anual de la campaña. El 2020, sin embargo, la Campaña Influenza tuvo que ser re-planificada en curso como consecuencia de la incorporación de nuevos grupos a vacunar según dispuso la modificación de la alerta sanitaria por brote de SARS-CoV-2 del 6 de marzo de 2020. Así, de 6.799.800 de dosis, el Departamento de Inmunizaciones logró en menos de dos meses aumentar la disponibilidad a 8.480.325, y cumplir con el compromiso de garantizar el acceso de los grupos de riesgo al beneficio de la vacunación estatal gratuita.

RESUMO

BACKGROUND: Insulin resistance (IR) precedes the diagnosis of many metabolic and non-metabolic illnesses, including type 2 diabetes mellitus (T2DM). Acanthosis nigricans (AN) is a clinical sign associated with IR. However, AN prevalence and diagnostic accuracy in middle-age adults before or at the time of prediabetes/diabetes diagnosis remain uncertain. METHODS: With the aim to define AN prevalence and diagnostic accuracy, adults between 40 and 60 years of age were consecutively invited to participate in the study. Participants were categorised into one of two main groups: individuals with normoglycaemia (group 1) and hyperglycaemia (group 2 [ie, prediabetes/diabetes]). Demographic, clinical, anthropometric characteristics, homeostasis model assessment of IR, homeostatic model assessment of ß-cell function, as well as the presence of AN on the neck, axillae, elbows and knuckles were assessed. RESULTS: A total of 320 consecutive participants with a mean age of 49.3 years (59.4% women) were included. Overall, AN prevalence was 46.3%, while AN in group 1 and group 2 was 36.3% and 49.6%, respectively (P = .04). The most common affected sites in group 1 (n = 80) were the knuckles (21.2%) and the neck (17.5%), while in group 2 (n = 240), the neck (29.6%) followed by the knuckles (26.7%). The specificity and positive predictive value of AN for IR were 0.85 and 0.86 in group 1 and 0.90 and 0.96 in group 2, respectively. CONCLUSIONS: In middle-age adults, within the entire spectrum of carbohydrate tolerance, AN is highly prevalent and specific. This finding supports its assessment as a reliable and convenient clinical sign of IR. The understanding of AN behaviour through different carbohydrate tolerance strata, and its different locations, could lead to early detection of individuals at high metabolic risk or help direct a more pathophysiological treatment approach in patients with T2DM.
