Application of deep convolutional neural networks for the detection of anthracnose in olives using VIS/NIR hyperspectral images
2021
Abstract Anthracnose is one of the primary diseases that affect olive production before and after harvest, causing severe damage and economic losses. The objective of this work is to detect this disease in the early stages, using hyperspectral images and advanced modelling techniques of Deep Learning (DL) and convolutional neural networks (CNN). The olives were artificially inoculated with the fungus. Hyperspectral images (450–1050 nm) of each olive were acquired until visual symptoms of the disease were observed, in some cases up to 9 days. The olives were classified into two classes: control, inoculated with water, and fungi composed of olives inoculated with the fungus. The ResNet101 arc…
Invagination of the Sphenoid Sinus Mucosa after Endoscopic Endonasal Transsphenoidal Approach and Its Significance
2016
Objective To describe the clinical features of invagination of the sphenoid sinus mucosa (ISM) and compare them with other similar cases using a visual analog scale (VAS) to assess the various nasal symptoms and to discuss its clinical significance and means of prevention. Study design Retrospective chart review at a tertiary referral center. Methods Between 2010 and 2015, 8 patients who had undergone EETSA surgery displayed postoperative ISM. The comparison group consisted of 147 patients who underwent the same surgical procedures and were diagnosed with the same diseases. Pre- or postoperative paranasal sinus computed tomography (PNS CT) and VAS were performed and subsequently analyzed. R…
Recurrence in a patient with a 10-year history of sinonasal mucosal melanoma manifesting as facial swelling
2017
Sinonasal mucosal melanoma is a rare tumor that develops slowly and may manifest with non specific signs and symptoms, causing significant delay in diagnosis. Local recurrence is common and usually occurs within the first two years after the initial treatment. Prognosis of recurrent lesions is poor and 5-year survival ranges between 10-47%. We report the clinical, radiographic, histopathological and immunohistochemical findings of a recurrent sinonasal mucosal melanoma which was diagnosed 10 years after the initial treatment, in a patient who presented with unilateral facial swelling and one-sided difficulty in breathing of two years duration. We discuss the causes of late diagnosis and rev…
Translational Research in Neuroimmunology: Cognition
2021
Cognitive impairment affects up to 70% of patients with multiple sclerosis (MS). It may already be present in the early stages of disease and impedes with a patient’s ability to maintain employment, take part in activities of daily life, and fully participate in society. Similar to the clinical heterogeneity of MS, there is great variability in cognitive symptoms among patients. Given the impact of such deficits on everyday functioning, an increasing interest in diagnosis and treatment of cognitive impairment has arisen. This chapter aims to present an overview of those cognitive domains most commonly affected in MS, common approaches to assess the respective cognitive functions as well as …
Time Hurries on but Does not Fly in Older Age — No Effect of Depressive Symptoms
2021
Abstract Research on the commonly known phenomenon of perceived accelerated time passage with increasing age has provided inconsistent results. This could be due to a mediating time-slowing effect of depressive symptoms as the prevalence of depression does also alter with age. Based on a large sample of 380 subjects covering a continuous range of age between 20 and 70 years, we tested whether the assumed age-related effect on time perception is being mediated by symptoms of depression. Cross-sectional differences indicate a weak, but significant nonlinear acceleration of the perceived passage of time especially during mid-adulthood, whereas no further alteration was observed above the age o…
Psychological models of development of idiopathic environmental intolerances: Evidence from longitudinal population-based data.
2021
Abstract The origin of idiopathic environmental intolerances (IEIs) is an open question. According to the psychological approaches, various top-down factors play a dominant role in the development of IEIs. The general psychopathology model assumes a propensity towards mental ill-health (negative affectivity) increases the probability of developing IEIs. The attribution model emphasizes the importance of mistaken attribution of experienced somatic symptoms; thus, more symptoms should lead to more IEIs. Finally, the nocebo model highlights the role of expectations in the development of IEIs. In this case, worries about the harmful effects of environmental factors are assumed to evoke IEIs. We…
“Symptoms associated with environmental factors” (SAEF) – Towards a paradigm shift regarding “idiopathic environmental intolerance” and related pheno…
2020
Health conditions characterized by symptoms associated with chemical, physical and biological environmental factors unrelated to objectifiable pathophysiological mechanisms are often labelled by the general term “idiopathic environmental intolerances”. More specific, exposure-related terms are also used, e.g. “multiple chemical sensitivities”, “electromagnetic hypersensitivity” and “candidiasis hypersensitivity”. The prevalence of the conditions varies from a few up to more than 50%, depending on definitions and populations. Based on evolving knowledge within this field, we provide arguments for a paradigm shift from terms focusing on exposure and intolerance/(hyper-)sensitivity towards a t…
Imaging Findings in Non-Cirrhotic Liver
2011
With the widespread use of cross-sectional imaging examinations, physicians from a wide array of specialties are becoming involved with questions regarding the management of patients with focal liver lesions. To formulate a practical approach to these patients, several factors must be incorporated into a clinical decision-making algorithm, including the clinical setting (e.g., known comorbidities, underlying cirrhosis or a known primary neoplasm), the presence of clinical signs and symptoms, the results of laboratory tests, and the critical information provided by imaging studies. In this chapter, we will briefly review important technical factors for optimization of CT protocols for the ev…
The Eveningness Chronotype and Lower Adherence to the Mediterranean Diet Are Associated With Depressive Symptoms in Older Subjects With Metabolic Syn…
2021
OBJECTIVES: Studies have shown the importance of depression as a risk factor for several diseases. Likewise, currently there is great interest on the role of chronotype in depressive disorders. Similarly, associations between diet and depression have been reported. However, very few studies have analyzed the combined effect of diet and chronotype on depression. Our aim was to investigated the joint influence of the morning/evening chronotype and adherence to the Mediterranean diet (MeDiet) on depressive symptoms in older subjects with metabolic syndrome. METHODS: We analyzed 465 PREDIMED Plus-Valencia study participants (aged 55–75). We assessed depressive symptoms by the Beck Depression In…
Adhd-like symptoms in children affected by obstructive sleep apnea syndrome: A case-control study
2016
Introduction: ADHD is characterized by inattention, hyperactivity, impulsivity, or a combination of these symptoms. Sleep disorders may be considered as a not secondary underlying cause of ADHD and growing evidence evidenced that obstructive sleep apnea syndrome (OSA) symptoms may overlap ADHD's ones. Aim of the present study is verifying the presence of ADHD-like symptoms in other frequent condition such as sleep-related breathing disorders in pediatric age. Materials and methods: 34 children (19 males and 15 females) aged 6-10 years (mean age 9.706 ± 3.434) with polysomnographic diagnosis of OSA, according to ICSD-3 criteria, were recruited. Control group was composed by 89 typical develo…
