The aim of this study was to assess the presence of burnout among neurologists caring for patients with cognitive disorders and to identify associated factors.

Changes in the potential distribution of the guava fruit fly (Diptera, Tephritidae) under current and possible future climate scenarios in Colombia.

Climate change has affected the geographical distributions of most species worldwide; in particular, insects of economic importance inhabiting tropical regions have been impacted. Current and future predictions of change in geographic distribution are frequently included in species distribution models (SDMs). The potential spatial distributions of the fruit fly Schiner, the main species of agricultural importance in guava crops, under current and possible future scenarios in Colombia were modeled, and the establishment risk was assessed for each guava-producing municipality in the country.

Norovirus Foodborne Outbreak Associated With the Consumption of Ice Pop, Southern Brazil, 2020.

Norovirus is a major cause of foodborne-associated acute gastroenteritis (AGE) outbreaks worldwide. Usually, food products are contaminated either during harvesting or preparation, and the most common products associated to norovirus outbreaks are raw or undercooked bivalve shellfish, fruits (frozen berries) and ready-to-eat produce. In the present study, we investigated an AGE outbreak caused by norovirus associated with the consumption of ice pops in southern Brazil.

Introduction: Unemployment is a significant problem for people with multiple sclerosis (MS). The MS Work Difficulties Questionnaire (MSWDQ-23) is a self-report tool to assess work-related problems in people with MS across three domains: physical, psychological/cognitive, and external barriers. The aim of this study was to assess the psychometric properties of the Spanish version of the MSWDQ-23.

On Integrated Residency in Health with emphasis on Health Surveillance.

Taking into account the four underpinning areas of Health Surveillance (environmental, epidemiological, health and worker's health), the performance of professionals in this area requires a broad and complex set of information from many fields of knowledge, including that which is not classified as health. Considering the need to prepare professionals to work in Health Surveillance in the Unified Health System (SUS), integrating the four fields of knowledge, the Public Health School of Rio Grande do Sul (ESP/RS) and the surveillance areas of the municipality of Porto Alegre and Rio Grande do Sul State have established a new emphasis in the traditional residency of ESP/RS. This work uses the experience report descriptive method.

Complete mitochondrial genome of the Andean morphotype of (Wiedemann) (Diptera: Tephritidae).

The South America fruit fly is an important pest of fruits in Latin America and it is really a complex with at least eight cryptic species. In this work, we report the complete mitochondrial genome for the Andean morphotype of . The mitochondrial genome is 16,739 nucleotides in size; includes 13 protein-coding genes, 22 tRNA genes, and 2 rRNA genes.

Characterization of the variable region in the class 1 integron of antimicrobial-resistant Escherichia coli isolated from surface water.

Fecal bacteria are considered to be a potential reservoir of antimicrobial resistance genes in the aquatic environment and could horizontally transfer these genes to autochthonous bacteria when carried on transferable and/or mobile genetic elements. Such circulation of resistance genes constitutes a latent public health hazard. The aim of this study was to characterize the variable region of the class 1 integron and relate its genetic content to resistance patterns observed in antimicrobial-resistant Escherichia coli isolated from the surface waters of Patos Lagoon, Southern Brazil.

Characterisation of the chemical profiles of Brazilian and Andean morphotypes belonging to the Anastrepha fraterculus complex (Diptera, Tephritidae).

Fruit fly sexual behaviour is directly influenced by chemical and non-chemical cues that play important roles in reproductive isolation. The chemical profiles of pheromones and cuticular hydrocarbons (CHs) of eight fruit fly populations of the Andean, Brazilian-1 and Brazilian-3 morphotypes of the Anastrepha fraterculus cryptic species complex originating from Colombia (four populations) and Brazil (four populations) were analysed using two-dimensional gas chromatography with mass spectrometric detection. The resulting chemical diversity data were studied using principal component analyses.

Taxonomy and phenotypic relationships of the Anastrepha fraterculus complex in the Mesoamerican and Pacific Neotropical dominions (Diptera, Tephritidae).

Previous morphometric studies based on linear measurements of female structures of the aculeus, mesonotum, and wing revealed the existence of seven morphotypes within the Anastrepha fraterculus cryptic species complex along the Neotropical Region. The current research followed linear and geometric morphometric approaches in 40 population samples of the nominal species Anastrepha fraterculus (Wiedemann) spread throughout the Meso-American and Pacific Neotropical dominions (including Mexico, Central America, Venezuela, Colombia, Ecuador, and Peru). The goals were to explore the phenotypic relationships of the morphotypes in these biogeographical areas; evaluate the reliability of procedures used for delimitation of morphotypes; and describe their current distribution.

Morphometric divergence in populations of Anastrepha obliqua (Diptera, Tephritidae) from Colombia and some Neotropical locations.

The West Indian fruit fly, Anastrepha obliqua, is one of seven species of quarantine importance of its genus and is one of the most economically important fruit fly pests in Colombia. The taxonomic status of this species is a key issue for further implementation of any pest management program. Several molecular studies have shown enough variability within Anastrepha obliqua to suggest its taxonomic status could be revised; however, there are no morphological studies supporting this hypothesis.

Morphometric study of third-instar larvae from five morphotypes of the Anastrepha fraterculus cryptic species complex (Diptera, Tephritidae).

The occurrence of cryptic species among economically important fruit flies strongly affects the development of management tactics for these pests. Tools for studying cryptic species not only facilitate evolutionary and systematic studies, but they also provide support for fruit fly management and quarantine activities. Previous studies have shown that the South American fruit fly, Anastrepha fraterculus, is a complex of cryptic species, but few studies have been performed on the morphology of its immature stages.

Two new species of Anastrepha Schiner (Diptera, Tephritidae) closely related to Anastrepha pickeli Lima.

Anastrepha entodonta n. sp. and Anastrepha hadropickeli n.

A new multidisciplinary home care telemedicine system to monitor stable chronic human immunodeficiency virus-infected patients: a randomized study.

Background: Antiretroviral therapy has changed the natural history of human immunodeficiency virus (HIV) infection in developed countries, where it has become a chronic disease. This clinical scenario requires a new approach to simplify follow-up appointments and facilitate access to healthcare professionals.

Methodology: We developed a new internet-based home care model covering the entire management of chronic HIV-infected patients.

Cyclobutane amino acid analogues of furanomycin obtained by a formal [2 + 2] cycloaddition strategy promoted by methylaluminoxane.

The synthesis and conformational analysis of a new type of conformationally restricted alpha-amino acid analogue of the amino acid antibiotic furanomycin is presented. The restriction involves the cis-fused cyclobutane and tetrahydrofuran units, generating the unusual 2-oxabicyclo[3.2.

Relationship between PPI and baseline startle response.

Prepulse inhibition (PPI) of the startle response to a sudden noise is the reduction in startle observed when the noise is preceded shortly by a mild sensory event, which is often a tone. A part of the literature is based on the assumption that PPI is independent of the baseline startle. A simple model is presented and experimental validation provided.

Time course of the evolution of malic and lactic acids in the alcoholic and malolactic fermentation of grape must by quantitative 1H NMR (qHNMR) spectroscopy.

Quantitative NMR can be used to monitor several processes that take place in the transformation of the must of wine grapes. The study described here focused attention on monitoring of the malic and lactic acid levels during the alcoholic and malolactic fermentation processes. The method allows the simultaneous quantification of both acids through a range of 1-3.

Selective Michael-aldol reaction by use of sterically hindered aluminum aryloxides as Lewis acids: an easy approach to cyclobutane amino acids.

A formal [2 + 2] cycloaddition of 2-amidoacrylates with monosubstituted donor olefins, including its asymmetric version, is described. The stereoselectivity of this reaction can be modulated by the use of sterically hindered aluminum aryloxides or methylaluminoxane as Lewis acids. The reaction was applied to the synthesis of both stereoisomers of 2-benzyloxycyclobutane-alpha-amino acid, which are protected serine analogues c(4)Ser(OBn).

Specific impairments of selective attention in mild Alzheimer's disease.

The aim of the present study was to evaluate selective visual attention in subjects affected by Alzheimer's Disease (AD), by means of a computerized spatial exploration test that adopts a Touch Screen (TS) interface, which has already proved able to characterize alternative strategies in performing search tasks. We assessed a group of 16 patients affected by mild to moderate AD, comparing them with 16 control subjects matched for age and education. In the experimental tasks the performance of the AD patients was worse than that of the normal elderly, both quantitatively (slower speeds) and qualitatively (poorer planning and higher number of omissions and perseverations).

Brain tissue damage in dementia with Lewy bodies: an in vivo diffusion tensor MRI study.

The aim of the present study was to apply diffusion tensor MRI (DT-MRI), a quantitative MRI measure which reflects tissue organization, to dementia with Lewy bodies (DLB). DT-MRI scans were obtained from 15 patients with probable DLB and 10 sex- and age-matched healthy controls. Abnormalities were found in the corpus callosum, pericallosal areas and the frontal, parietal, occipital and, less prominently, temporal white matter of patients compared with controls.

A new promoter polymorphism in the alpha-1-antichymotrypsin gene is a disease modifier of Alzheimer's disease.

Increased levels of alpha-1-antichymotrypsin (ACT), a protease inhibitor and an acute phase protein, have been found in the brain and peripheral blood of patients with Alzheimer's disease (AD). Patients from northern Italy with a clinical diagnosis of probable AD, and patients with early onset AD (EOAD) from UK with AD neuropathological diagnosis were genotyped for a new polymorphism in the promoter region of the ACT gene which has been shown to affect ACT expression. A subset of patients with clinical AD from northern Italy was also followed up for 2 years and monitored for cognitive decline.

Synthesis of cyclobutane serine analogues.

In this paper, we describe a thermal [2 + 2] cycloaddition involving 2-acylaminoacrylates as electron-poor acceptor alkenes, a reaction that involves a Michael-Dieckmann-type process. The reaction gives rise to a new substituted cyclobutane skeleton that can be transformed into amino acid derivatives. For example, a number of transformations were carried out to give the two pairs of stereoisomers of the 2-hydroxycyclobutane-alpha-amino acid serine analogue (c(4)Ser); compounds 22 and 23.
