Aspiration is the most serious complication of dysphagia, which may lead to pneumonia. Detection of aspiration is limited by the presence of its signs like coughing and choking, which may be absent in many cases. High resolution cervical auscultations (HRCA) represent a promising non-invasive method intended for the detection of swallowing disorders. In this study, we investigate the potential of HRCA in detection of penetration-aspiration in patients suspected of dysphagia. A variety of features were extracted from HRCA in both time and frequency domains and they were tested for association with the presence of penetration-aspiration. Multiple classifiers were implemented also for aspiration detection using the extracted signal features. The results showed the presence of strong association between some HRCA signal features and penetration-aspiration, furthermore, they direct towards future directions to enhance prediction capability of aspiration using HRCA signals.

Background: The aim of the study was to highlight the importance of adequate anticoagulant therapy and the correlation of higher risk of stroke. Methods: This study analyzed data obtained from 103 patients with diagnosis of atrial fibrillation (AF) (39 of them had a stroke). Patients were divided into groups according to the CHADS2, CHA2DS2-VASc, and HASBLED scores. Results: An analysis showed that anticoagulant drugs were more often prescribed to subjects <75 years of age (P = 0.001). Patients with a higher CHADS2 score had a higher CHA2DS2-VASc score and vice versa (rho = 0.513; P = 0.0001). According to the CHA2DS2-VASc, 91.3% of the patients examined were prescribed an anticoagulant medication as a therapy at discharge from the hospital. The result was statistically significant compared to the practice where an anticoagulant was prescribed to 55.9% of high-risk subjects as estimated by the CHA2DS2-VASc score (P < 0.05). Our results also show that rivaroxaban is more commonly prescribed as a discharge therapy than warfarin (χ2 = 12.401; P = 0.0001). Furthermore, a significantly higher number of patients who were being prescribed aspirin (38.5%) had a stroke compared to 12.8% of patients who were being prescribed warfarin (χ2 = 12.259; P = 0.0001). Conclusions: Novel oral anticoagulants (NOACs) seem to be a better choice as a pharmacological therapy in the treatment of AF, due to a lack of adequate monitoring of patients' international normalized ratio (INR) values. CHA2DS2-VASc and HASBLED scores must be used as a part of routine clinical diagnostics when dealing with patients with AF.

Australian & New Zealand Journal of Psychiatry, 53(12) Anorexia nervosa (AN) is associated with the highest death rate of any mental illness, among the highest relapse rates of any psychiatric condition, and a long-term recovery rate of less than 50% among those who survive it. Despite AN first being described in the scientific literature in the late 19th century, we have arguably made little progress in uncovering the aetiological and maintenance factors involved in the illness, and in developing effective treatments. This is in stark contrast to many other mental illnesses (e.g. schizophrenia, major depressive disorder) which have evidence-based treatments available that are largely successful in remitting symptoms. A recent systematic review and meta-analysis concluded that specialised eating disorder treatments are no more successful than control treatments in remitting the psychological symptoms of AN at end of treatment or follow-up; instead, they are only successful at increasing body weight at end of treatment which does not carry through to follow-up (Murray et al., 2019). Indeed, our current clinical practice guidelines for the treatment of eating disorders conclude that there is limited evidence to support current therapies for AN given the scarcity of randomised controlled trials (Hay et al., 2014). Why is this the case? Why have we failed to develop evidence-based treatments to specifically treat AN while so much progress has arguably been achieved in other mental illnesses? It is widely acknowledged that all mental illnesses involve, at least to some degree, both environmental and biological influences, i.e., nature and nurture. In AN, the biopsychosocial model of the illness is well accepted, with biological, psychological and sociocultural factors all thought to contribute to the development and maintenance of the condition. Historically, the greatest focus in AN research and treatment has, however, undoubtedly been on environmental factors contributing to the illness. The biological underpinnings of the condition, on the other hand, have been largely overlooked; and when biological mechanisms have been examined, there has been little consistency and replication between studies (Phillipou et al., 2014). Partly due to advances in technology, recent times have seen greater focus on the biological contributions to AN, including behavioural determinants of biological features on long-term outcomes, but still to a lesser degree than the psychological and sociocultural factors involved in the illness. The lack of a comprehensive biological framework has resulted in a paucity of neurobiologically inspired therapies specifically prescribed to treat AN, including psychotropic medications and brain stimulation techniques that are available to successfully treat other mental illnesses. Currently, the psychotropic medications prescribed to individuals with AN are often to alleviate the frequently comorbid symptoms of depression and/or anxiety rather than to treat the core neurobiological features of the illness. An additional problem is that the different factors of the biopsychosocial model of AN are not regularly assessed synergistically, and the majority of the literature in AN focuses on single or specific aspects of the model without integrating environmental and biological components. Almost all factors that are thought to contribute to the aetiology and maintenance of AN, or act as barriers to successful treatment, involve an interaction of environmental and biological influences. Figure 1 represents a proposed model of this interaction, with factors theoretically arranged by the degree of environmental and biological load. This model does not encompass all factors proposed to be involved in AN in the literature, but a summary of some of the most important influences described to date. Sociocultural and psychosocial factors are proposed to load the heaviest on the environmental end of the spectrum, whereas genetic influences (i.e. DNA) are proposed to load the heaviest on the biological end. However, even the factors on the opposite ends of the spectrum are not clear-cut. Psychosocial factors such as exposure to trauma, A biopsychosocial proposal to progress the field of anorexia nervosa
