Abstract Background There are very few developed countries where physical isolation and low community transmission has been reported for COVID-19 but this has been the experience of Australia. The impact of physical isolation combined with low disease transmission on the mental health of pregnant women is currently unknown and there have been no studies examining the psychological experience for partners of pregnant women during lockdown. The aim of the current study was to examine the impact of the first COVID-19 lockdown in March 2020 and post lockdown from August 2020 on the mental health of pregnant women or postpartum women and their partners. Methods Pregnant women and their partners were prospectively recruited to the study before 24 weeks gestation and completed various questionnaires related to mental health and general wellbeing at 24 weeks gestation and then again at 6 weeks postpartum. The Depression, Anxiety and Stress Scale (DASS-21) and the Edinburgh Postnatal Depression Scale (EPDS) were used as outcome measures for the assessment of mental health in women and DASS-21 was administered to their partners. This analysis encompasses 3 time points where families were recruited; before the pandemic (Aug 2018-Feb 2020), during lockdown (Mar-Aug 2020) and after the first lockdown was over (Sept-Dec 2020). Results There was no significant effect of COVID-19 lockdown and post lockdown on depression or postnatal depression in women when compared to a pre-COVID-19 subgroup. The odds of pregnant women or postpartum women experiencing severe anxiety was more than halved in women during lockdown relative to women in the pre-COVID-19 period (OR = 0.47; 95%CI: 0.27–0.81; P = 0.006). Following lockdown severe anxiety was comparable to the pre-COVID-19 women. Lockdown did not have any substantial effects on stress scores for pregnant and postpartum women. However, a substantial decrease of over 70% in the odds of severe stress was observed post-lockdown relative to pre-COVID-19 levels. Partner’s depression, anxiety and stress did not change significantly with lockdown or post lockdown. Conclusion A reproductive age population appear to be able to manage the impact of lockdown and the pandemic with some benefits related to reduced anxiety.

Introduction The perinatal–postnatal family environment is associated with childhood outcomes including impacts on physical and mental health and educational attainment. Family longitudinal cohort studies collect in-depth data that can capture the influence of an era on family lifestyle, mental health, chronic disease, education and financial stability to enable identification of gaps in society and provide the evidence for changes in government in policy and practice.Methods and analysis The Queensland Family Cohort (QFC) is a prospective, observational, longitudinal study that will recruit 12 500 pregnant families across the state of Queensland (QLD), Australia and intends to follow-up families and children for three decades. To identify the immediate and future health requirements of the QLD population; pregnant participants and their partners will be enrolled by 24 weeks of gestation and followed up at 24, 28 and 36 weeks of gestation, during delivery, on-ward, 6 weeks postpartum and then every 12 months where questionnaires, biological samples and physical measures will be collected from parents and children. To examine the impact of environmental exposures on families, data related to environmental pollution, household pollution and employment exposures will be linked to pregnancy and health outcomes. Where feasible, data linkage of state and federal government databases will be used to follow the participants long term. Biological samples will be stored long term for future discoveries of biomarkers of health and disease.Ethics and dissemination Ethical approval has been obtained from the Mater Research Ethics (HREC/16/MHS/113). Findings will be reported to (1) QFC participating families; (2) funding bodies, institutes and hospitals supporting the QFC; (3) federal, state and local governments to inform policy; (4) presented at local, national and international conferences and (5) disseminated by peer-review publications.

Corrosion degrades the surface of metals. Therefore, extracts of natural products are tested as possible corrosion inhibitors, in order to delay or inhibit such processes. These inhibitory substances can act via adsorption, forming a thin protective film that inhibits the anode and/or cathode processes on the surface. This study aimed to test the inhibitory efficiency of goji berry extract (GB) in the corrosion of SAE 1045 carbon steel. The extract was prepared by hydroethanolic extraction and was diluted with 0.5 mol L-1 NaCl electrolyte, for electrochemistry tests. The electrochemical impedance spectroscopy and anodic potentiodynamic polarization tests showed that the metal is more resistant to corrosion in the presence of the GB, because higher values of impedance and lower values of current density were obtained in the presence of the GB; the scanning electron microscopy data corroborated the electrochemical test results.

Abstract As connectivity and interactions on the internet and social media grew easier, it made it possible for any individual to create and disseminate information or news as desired, which resulted in the growth of disinformation, leading to questions of how human beings can be manipulated by false information. The main objective of this research is to correlate the concepts of false news and misinformation with Fogg’s Behavior Model. By considering the correlation between the definitions and concepts applied by the selected bodies and institutions and the factors of Fogg’s Behavior Model, we conclude that all the definitions have aspects correlated with the factors raised by Fogg for the persuasion toward a desired behavior, thus showing how false information can be used to manipulate individuals who are likely to believe in a certain topic, those who do not have knowledge of verifiability procedures for misinformation or those who have already been affected by informational fatigue.

Verificar ações relacionadas ao fluxo de caixa e a solução de problemas organizacionais; organizar entradas e saídas consistentes no fluxo especificando todas as receitas e despesas; analisar o lucro ou prejuízo; descobrir possíveis restrições de gastos. O trabalho foi realizado por meio de estudo de caso, entrevistas de natureza qualitativa e exploratória, sendo a coleta de dados realizada através de um questionário destinado a 25 stakeholders dentro de apenas uma empresa do setor imobiliário. Observou-se que para realização do fluxo de caixa de forma sólida uma única pessoa deve realiza-lo. Diante do exposto as implicações mais relevantes foram que o fluxo de caixa elaborado de forma sólida possibilita o alavanque dos investimentos e tomada de decisão de forma estratégica dentro da organização.

Esta pesquisa pretende demonstrar como trabalhadores que exercem profissões subjulgadas sentem-se em relação ao seu trabalho, ao ambiente onde executam suas atividades e as pessoas que fazem parte deste local. Buscamos entender, através da visão dos empregados terceirizados - do setor de limpeza –, e analisar, sob a ótica da sociologia do trabalho, o ambiente de trabalho dessas mulheres para demonstrar a precariedade do serviço dentro da Faculdade de Direito da UFMG e sua influência no comportamento dessas trabalhadoras. Foram utilizados questionários qualitativos para o levantamento de dados, juntamente com rodas de bate papo, no intuito de ouvi-las, em busca de entender seus sentimentos para com o trabalho nas diversas situações que permeiam seu dia a dia. Além disso, analisaremos como a terceirização do trabalho torna as relações entre empregador e empregado mais precárias e como as faxineiras são afetadas por esse fenômeno, em muitas situações, perdendo seus direitos e sendo acompanhadas por um sentimento de insegurança.

Bebidas alcoólicas são amplamente consumidas, porém o consumo não moderado representa prejuízos. Estudo transversal com o objetivo de determinar a prevalência do consumo de álcool entre acadêmicos de farmácia da Universidade Federal do Maranhão, em São Luís. Foram aplicados dois questionários entre maio e junho de 2011: o primeiro baseado em um modelo da Organização Mundial de Saúde e o segundo o teste CAGE (Cut down, Annoyed, Guilty, Eye-opened), que avalia dependência alcoólica. Participaram 76 estudantes com o seguinte perfil: 30 homens e 46 mulheres, faixa etária entre 17 e 32 anos e renda a partir de R$ 3.840,00. A prevalência do uso de álcool foi de 87%, sendo maior entre homens. O teste CAGE evidenciou que 4% apresentavam problemas físico-psíquicos. Destacou-se o fato de que 31% nunca receberam informações na faculdade sobre o consumo de álcool. Conclui-se que há necessidade de abordar esse tópico junto aos estudantes. ABSTRACT: Alcoholic beverages are widely consumed, but immoderate consumption is prejudicial. This cross-sectional study aimed to determine the prevalence of alcohol consumption among Pharmacy students at Maranhão Federal University, São Luís. Two questionnaires were applied between May and June of 2011, the first based on a World Health Organization model and the second, the CAGE (Cut down, Annoyed, Guilty, Eye-opened) test, which determines alcohol dependence. The sample consisted of 76 students with the following profile: 30 men and 46 women, from 17 to 32 years old with income ³ R$ 3,840.00. Overall prevalence of alcohol consumption was 87%, but higher among men. The CAGE test showed that 4% had physical and/or psychological problems. Strikingly, 31% received no information at college about alcohol consumption. It was concluded that this topic needs to be addressed with the students.
