Qualidade do emprego e condiçþes de vida dos trabalhadores rurais nas culturas do cafĂŠ e da cana-de-açúcar na mesorregiĂŁo do Triângulo Mineiro e Alto ParanaĂba entre 2000 e 2010.
Trabalho de ConclusĂŁo de Curso (Graduação)Este trabalho tem como objetivo estudar a qualidade do emprego e as condiçþes de vida dos empregados rurais da mesorregiĂŁo do Triângulo Mineiro e Alto ParanaĂba (TMAP). Para isso, foram selecionados grupos de empregados com e sem carteira assinada, nas atividades cafeeira e canavieira. Considerando os processos de modernização e mecanização que acontecem nas culturas, causando uma redução dos postos de trabalho agrĂcolas desqualificados e em contrapartida aumentando os postos qualificados, juntamente com expansĂŁo da produção na cultura da cana-de-açúcar que alterou a dinâmica da mesorregiĂŁo, buscamos analisar como isso impacta no mercado de trabalho, comparando os anos 2000 e 2010 e destacando se a qualidade do emprego e as condiçþes de vida para estes empregados melhoram durante a dĂŠcada. Para a construção dos indicadores parciais, do Ăndice de Qualidade do Emprego (IQE) e do Ăndice de Condiçþes de Vida (ICV) foram utilizados dados do Censo DemogrĂĄfico de 2000 e de 2010 do IBGE. Os resultados obtidos demonstram, a partir da evolução dos Ăndices IQE e ICV, que os empregados do final do perĂodo, na maioria dos casos mais qualificados, nĂŁo necessariamente sĂŁo os que tĂŞm a melhor qualidade do emprego e as melhores condiçþes de vida, principalmente em decorrĂŞncia do desempenho dos indicadores de rendimento, que tiveram queda quase sempre, ao longo do perĂodo
Transmission of Hemagglutinin D222G Mutant Strain of Pandemic (H1N1) 2009 Virus
A pandemic (H1N1) 2009 virus strain carrying the D222G mutation was identified in a severely ill man and was transmitted to a household contact. Only mild illness developed in the contact, despite his obesity and diabetes. The isolated virus reacted fully with an antiserum against the pandemic vaccine strain
Solar energy systems in architecture - Integration criteria and guidelines
This document is conceived for architects and intended to be as clear and practical as possible. It summarizes the knowledge needed to integrate active solar technologies (solar thermal and photovoltaics) into buildings, handling at the same time architectural integration issues and energy production requirements. Solar thermal and photovoltaics are treated separately, but the information is given following the same structure: 1- Main technical information; 2- Constructive/functional integration possibilities in the envelope layers; 3- System sizing and positioning criteria; 4- Good integration examples; 5- Formal flexibility offered by standard products; 6 - Innovative market products. To complete the information the manual ends with a short section dedicated to the differences and similarities between solar thermal and photovoltaic systems, with the purpose to help architects make an energetic and architecturally optimized use of the sun exposed surfaces of their buildings
A Comparison of Divergent Thinking Abilities Between Healthy Elderly Subjects and MCI Patients: Preliminary Findings and Implications
Objective: Divergent thinking (DT) has attracted research interest because of its
potential role in early diagnosis and rehabilitation programs for patients affected by
neurodegenerative diseases. Recently, DT has received even more attention because of
its proven relationship with cognitive reserve (CR) and the possibility of a standardized
assessment. However, few studies have investigated this ability in dementia patients,
and even less is known about patients affected by Mild Cognitive Impairment (MCI).
Thus, this study aims to investigate DT abilities in MCI patients.
Methods: A total of 25 MCI patients and 25 healthy controls subjects (HC; from
a random selection of 50) matched for age, gender, and educational level were
enrolled. General cognitive functioning was measured by the Montreal Cognitive
Assessment (MoCA), while the Abbreviated Torrance Test for Adults (ATTA) was
selected to measure DT.
Results: MANOVA analysis did not reveal any significant differences in DT abilities
between MCI patients and HC except for the figural indicator score. A logistic
hierarchical regression analysis revealed that the figural indicator score added an 8%
of accuracy in the prediction of the group variable over the general cognition measure
(MoCA).
Conclusion: MCI patients seem to perform significantly worse than HC only in the
figural DT score and this evidence has significant practical implications. First, that figural
DT seemed to decrease even earlier than verbal DT and could therefore be taken into
account for early diagnosis of MCI patients. On the contrary, the sparing of all the other
DT skills (such as verbal DT skills, fluency, flexibility, originality, and elaboration) may
suggest that, given its relationship with CR, verbal DT could instead be considered a
possible target for prevention or early cognitive stimulation interventions
Correlative multi-scale cryo-imaging unveils SARS-CoV-2 assembly and egress.
Funder: Medical Research CouncilSince the outbreak of the SARS-CoV-2 pandemic, there have been intense structural studies on purified viral components and inactivated viruses. However, structural and ultrastructural evidence on how the SARS-CoV-2 infection progresses in the native cellular context is scarce, and there is a lack of comprehensive knowledge on the SARS-CoV-2 replicative cycle. To correlate cytopathic events induced by SARS-CoV-2 with virus replication processes in frozen-hydrated cells, we established a unique multi-modal, multi-scale cryo-correlative platform to image SARS-CoV-2 infection in Vero cells. This platform combines serial cryoFIB/SEM volume imaging and soft X-ray cryo-tomography with cell lamellae-based cryo-electron tomography (cryoET) and subtomogram averaging. Here we report critical SARS-CoV-2 structural events - e.g. viral RNA transport portals, virus assembly intermediates, virus egress pathway, and native virus spike structures, in the context of whole-cell volumes revealing drastic cytppathic changes. This integrated approach allows a holistic view of SARS-CoV-2 infection, from the whole cell to individual molecules
COVID-19 in rheumatic diseases in Italy: first results from the Italian registry of the Italian Society for Rheumatology (CONTROL-19)
OBJECTIVES:
Italy was one of the first countries significantly affected by the coronavirus disease 2019 (COVID-19) epidemic. The Italian Society for Rheumatology promptly launched a retrospective and anonymised data collection to monitor COVID-19 in patients with rheumatic and musculoskeletal diseases (RMDs), the CONTROL-19 surveillance database, which is part of the COVID-19 Global Rheumatology Alliance.
METHODS:
CONTROL-19 includes patients with RMDs and proven severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) updated until May 3rd 2020. In this analysis, only molecular diagnoses were included. The data collection covered demographic data, medical history (general and RMD-related), treatments and COVID-19 related features, treatments, and outcome. In this paper, we report the first descriptive data from the CONTROL-19 registry.
RESULTS:
The population of the first 232 patients (36% males) consisted mainly of elderly patients (mean age 62.2 years), who used corticosteroids (51.7%), and suffered from multi-morbidity (median comorbidities 2). Rheumatoid arthritis was the most frequent disease (34.1%), followed by spondyloarthritis (26.3%), connective tissue disease (21.1%) and vasculitis (11.2%). Most cases had an active disease (69.4%). Clinical presentation of COVID-19 was typical, with systemic symptoms (fever and asthenia) and respiratory symptoms. The overall outcome was severe, with high frequencies of hospitalisation (69.8%), respiratory support oxygen (55.7%), non-invasive ventilation (20.9%) or mechanical ventilation (7.5%), and 19% of deaths. Male patients typically manifested a worse prognosis. Immunomodulatory treatments were not significantly associated with an increased risk of intensive care unit admission/mechanical ventilation/death.
CONCLUSIONS:
Although the report mainly includes the most severe cases, its temporal and spatial trend supports the validity of the national surveillance system. More complete data are being acquired in order to both test the hypothesis that RMD patients may have a different outcome from that of the general population and determine the safety of immunomodulatory treatments
Beta-Blocker Use in Older Hospitalized Patients Affected by Heart Failure and Chronic Obstructive Pulmonary Disease: An Italian Survey From the REPOSI Register
Beta (β)-blockers (BB) are useful in reducing morbidity and mortality in patients with heart failure (HF) and concomitant chronic obstructive pulmonary disease (COPD). Nevertheless, the use of BBs could induce bronchoconstriction due to β2-blockade. For this reason, both the ESC and GOLD guidelines strongly suggest the use of selective β1-BB in patients with HF and COPD. However, low adherence to guidelines was observed in multiple clinical settings. The aim of the study was to investigate the BBs use in older patients affected by HF and COPD, recorded in the REPOSI register. Of 942 patients affected by HF, 47.1% were treated with BBs. The use of BBs was significantly lower in patients with HF and COPD than in patients affected by HF alone, both at admission and at discharge (admission, 36.9% vs. 51.3%; discharge, 38.0% vs. 51.7%). In addition, no further BB users were found at discharge. The probability to being treated with a BB was significantly lower in patients with HF also affected by COPD (adj. OR, 95% CI: 0.50, 0.37-0.67), while the diagnosis of COPD was not associated with the choice of selective β1-BB (adj. OR, 95% CI: 1.33, 0.76-2.34). Despite clear recommendations by clinical guidelines, a significant underuse of BBs was also observed after hospital discharge. In COPD affected patients, physicians unreasonably reject BBs use, rather than choosing a β1-BB. The expected improvement of the BB prescriptions after hospitalization was not observed. A multidisciplinary approach among hospital physicians, general practitioners, and pharmacologists should be carried out for better drug management and adherence to guideline recommendations
The âDiabetes Comorbidomeâ: A Different Way for Health Professionals to Approach the Comorbidity Burden of Diabetes
(1) Background: The disease burden related to diabetes is increasing greatly, particularly in older subjects. A more comprehensive approach towards the assessment and management of diabetesâ comorbidities is necessary. The aim of this study was to implement our previous data identifying and representing the prevalence of the comorbidities, their association with mortality, and the strength of their relationship in hospitalized elderly patients with diabetes, developing, at the same time, a new graphic representation model of the comorbidome called âDiabetes Comorbidomeâ. (2) Methods: Data were collected from the RePoSi register. Comorbidities, socio-demographic data, severity and comorbidity indexes (Cumulative Illness rating Scale CIRS-SI and CIRS-CI), and functional status (Barthel Index), were recorded. Mortality rates were assessed in hospital and 3 and 12 months after discharge. (3) Results: Of the 4714 hospitalized elderly patients, 1378 had diabetes. The comorbidities distribution showed that arterial hypertension (57.1%), ischemic heart disease (31.4%), chronic renal failure (28.8%), atrial fibrillation (25.6%), and COPD (22.7%), were the more frequent in subjects with diabetes. The graphic comorbidome showed that the strongest predictors of death at in hospital and at the 3-month follow-up were dementia and cancer. At the 1-year follow-up, cancer was the first comorbidity independently associated with mortality. (4) Conclusions: The âDiabetes Comorbidomeâ represents the perfect instrument for determining the prevalence of comorbidities and the strength of their relationship with risk of death, as well as the need for an effective treatment for improving clinical outcomes
Antidiabetic Drug Prescription Pattern in Hospitalized Older Patients with Diabetes
Objective: To describe the prescription pattern of antidiabetic and cardiovascular drugs in a cohort of hospitalized older patients with diabetes. Methods: Patients with diabetes aged 65 years or older hospitalized in internal medicine and/or geriatric wards throughout Italy and enrolled in the REPOSI (REgistro POliterapuie SIMIâSocietĂ Italiana di Medicina Interna) registry from 2010 to 2019 and discharged alive were included. Results: Among 1703 patients with diabetes, 1433 (84.2%) were on treatment with at least one antidiabetic drug at hospital admission, mainly prescribed as monotherapy with insulin (28.3%) or metformin (19.2%). The proportion of treated patients decreased at discharge (N = 1309, 76.9%), with a significant reduction over time. Among those prescribed, the proportion of those with insulin alone increased over time (p = 0.0066), while the proportion of those prescribed sulfonylureas decreased (p < 0.0001). Among patients receiving antidiabetic therapy at discharge, 1063 (81.2%) were also prescribed cardiovascular drugs, mainly with an antihypertensive drug alone or in combination (N = 777, 73.1%). Conclusion: The management of older patients with diabetes in a hospital setting is often sub-optimal, as shown by the increasing trend in insulin at discharge, even if an overall improvement has been highlighted by the prevalent decrease in sulfonylureas prescription
