Effects of Acute Autonomic Modulation on Atrial Conduction Delay and Local Electrograms Duration in Paroxysmal Atrial Fibrillation

Slowed atrial conduction may contribute to reentry circuits and vulnerability for atrial fibrillation (AF). The autonomic nervous system (ANS) has modulating effects on electrophysiological properties. However, complex interactions of the ANS with the arrhythmogenic substrate make it difficult to understand the mechanisms underlying induction and maintenance of AF. AIM: To determine the effect of acute ANS modulation in atrial activation times in patients (P) with paroxysmal AF (PAF). METHODS AND RESULTS: 16P (9 men; 59±14years) with PAF, who underwent electrophysiological study before AF ablation, and 15P (7 men; 58±11years) with atrioventricular nodal reentry tachycardia, without documentation or induction of AF (control group). Each group included 7P with arterial hypertension but without underlying structural heart disease. The study was performed while off drugs. Multipolar catheters were placed at the high right atrium (HRA), right atrial appendage (RAA), coronary sinus (CS) and His bundle area (His). At baseline and with HRA pacing (600ms, shortest propagated S2) we measured: i) intra-atrial conduction time (IACT, between RAA and atrial deflection in the distal His), ii) inter-atrial conduction time (interACT, between RAA and distal CS), iii) left atrial activation time (LAAT, between atrial deflection in the distal His and distal CS), iv) bipolar electrogram duration at four atrial sites (RAA, His, proximal and distal CS). In the PAF group, measurements were also determined during handgrip and carotid sinus massage (CSM), and after pharmacological blockade of the ANS (ANSB). AF was induced by HRA programmed stimulation in 56% (self-limited - 6; sustained - 3), 68.8% (self-limited - 6; sustained - 5), and 50% (self-limited - 5; sustained - 3) of the P, in basal, during ANS maneuvers, and after ANSB, respectively (p=NS). IACT, interACT and LAAT significantly lengthened during HRA pacing in both groups (600ms, S2). P with PAF have longer IACT (p<0.05), a higher increase in both IACT, interACT (p<0.01) and electrograms duration (p<0.05) with S2, and more fragmented activity, compared with the control group. Atrial conduction times and electrograms duration were not significantly changed during ANS stimulation. Nevertheless, ANS maneuvers increased heterogeneity of the local electrograms duration. Also, P with sustained AF showed longer interACT and LAAT during CSM. CONCLUSION: Atrial conduction times, electrograms duration and fractionated activity are increased in PAF, suggesting a role for conduction delays in the arrhythmogenic substrate. Acute vagal stimulation is associated with prolonged interACT and LAAT in P with inducible sustained AF and ANS modulation may influence the heterogeneity of atrial electrograms duration.

Application of Infrared Thermal Imaging in a Violinist with Temporomandibular Disorder

Temporomandibular disorders (TMD) consist of a group of pathologies that affect the masticatory muscles, temporomandibular joints (TMJ), and/or related structures. String instrumentalists, like many orchestra musicians, can spend hours with head postures that may influence the biomechanical behavior of the TMJ and the muscles of the craniocervicomandibular complex (CCMC). The adoption of abnormal postures acquired during performance by musicians can lead to muscular hyperactivity of the head and cervical muscles, with the possible appearance of TMD. Medical infrared thermography is a non-invasive procedure that can monitor the changes in the superficial tissue related to blood circulation and may serve as a complement to the clinical examination. The objective of this study was to use infrared thermography to evaluate, in one subject, the cutaneous thermal changes adjacent to the CCMC that occur before, during, and after playing a string instrument.

Desenvolvimento de um serviço local de Saúde Mental em Famalicão

RESUMO: O desenvolvimento de serviços locais adequados deve ser baseado numa avaliação sistemática das necessidades e resultados obtidos nos cuidados a uma população de indivíduos identificados como apresentando uma doença mental na área de referenciação do serviço. Neste sentido foram utilizados os seguintes métodos: dados epidemiológicos acerca das necessidades locais e taxas de utilização de serviços a nível nacional e local, este último com base no case-register. Os diagnósticos de maior prevalência em ambulatório são as perturbações de humor e as perturbações neuróticas de stress ou somatoformes, com uma preponderância de doenças mentais comuns (depressão e ansiedade) em serviços de psiquiatria. Constatam-se baixas taxas de abandono da consulta (12%). A idade, a doença e a escolaridade estão correlacionados com o risco de drop-out, mas utilizada a regressão logística, a idade e a escolaridade perdem o seu significado estatístico. Encontram-se taxas reduzidas de drop-out dos indivíduos com psicose ou perturbações bipolares, em virtude da intervenção activa da equipa. Os custos de transporte, a distância ao local de consulta e o tempo de espera para a primeira consulta são barreiras no acesso aos cuidados a nível local. Os cuidadores não se sentem apoiados pela rede de suporte social e queixam-se sobretudo da acessibilidade, mas exibem elevadas taxas de satisfação com os serviços prestados. Decidiu-se apostar numa organização do serviço baseada na comunidade, com intervenções baseadas na evidência, dando prioridade ao doente mental grave e à qualidade dos cuidados.----------- ABSTRACT: The development of appropriate local services should be based on a systematic assessment of the needs and outcomes of the population of individuals identified as mentally ill within the service’s catchment area. A number of methods may be used as proxies in assessing local needs for services, such as service utilization rates found nationally and locally, by case-register. The most prevalent diagnoses in ambulatory care are mood disorders and neurotic, stress and somatoform disorders, with a majority of common mental disorders (depression and anxiety) in psychiatric services. Low dropout rates (12%) are found in ambulatory care. Age, disease and education are correlated with the risk of drop-out, but after using logistic regression, age and education lose their statistical significance. Low drop-out rates are found in individuals with psychosis or bipolar disorders, because the active intervention from the team. The costs of transportation, distance and the waiting time for the first consultation are barriers in access of care locally. Carers do not feel supported by the network of social support and complain primarily of accessibility, but exhibit high levels of satisfaction with the services provided. It was decided to invest in a service organization based in the community with evidence-based interventions, giving priority to severe mental illness and quality of care.

Delineating environmental groundwater vulnerability and protection zones mapping in fractured rock masses

Hard‐rock watersheds commonly exhibit complex geological bedrock and morphological features. Hydromineral resources have relevant economic value for the thermal spas industry. The present study aims to develop a groundwater vulnerability approach in Caldas da Cavaca hydromineral system (Aguiar da Beira, Central Portugal) which has a thermal tradition that dates back to the late 19th century, and contribute to a better understanding of the hydrogeological conceptual site model. In this work different layers were overlaid, generating several thematic maps to arrive at an integrated framework of several key‐sectors in Caldas da Cavaca site. Thus, to accomplish a comprehensive analysis and conceptualization of the site, a multi‐technical approach was used, such as, field and laboratory techniques, where several data was collected, like geotectonics, hydrology and hydrogeology, hydrogeomorphology, hydrogeophysical and hydrogeomechanical zoning aiming the application of the so‐called DISCO method. All these techniques were successfully performed and a groundwater vulnerability to contamination assessment, based on GOD‐S, DRASTIC‐Fm, SINTACS, SI and DISCO indexes methodology, was delineated. Geographical Information Systems (GIS) technology was on the basis to organise and integrate the geodatabases and to produce all the thematic maps. This multi‐technical approach highlights the importance of groundwater vulnerability to contamination mapping as a tool to support hydrogeological conceptualisation, contributing to better decision‐making of water resources management and sustainability.
