Struktur Komunitas Fitoplankton di Perairan yang Terdampak Air Bahang PLTU Paiton Kabupaten Probolinggo Jawa Timur
PLTU Paiton merupakan salah satu pembangkit listrik tenaga uap menggunakan air sebagai pendingin kondensor kemudian dikembalikan lagi ke perairan sekitar sebagai air bahang, sehingga akan memberikan input panas bagi perairan. Meningkatnya suhu perairan akibat air bahang ini, secara langsung maupun tidak langsung akan berpengaruh terhadap komponen biotik dan abiotik penyusun ekosistem laut, salah satu yang akan terpengaruh adalah fitoplankton yakni berupa struktur komunitas yang meliputi keanekaragaman, kelimpahan jenis, maupun keseragaman jenis fitoplankton disuatu perairan. Dari deskripsi tersebut, maka dilakukan penelitian mengenai struktur komunitas fitoplankton di perairan yang terdampak air bahang PLTU Paiton yang dilakukan pada bulan Maret hingga Juni 2015 dengan 6 kali pengambilan sampel di lima titik sekitar PLTU Paiton (Mercusuar, Intake, Outlet, Banyuglugur, dan Tengah). Data struktur komunitas yang diambil berupa kelimpahan, keanekaragaman, dan keseragaman fitoplankton yang selanjutnya dianalisis secara deskriptif kuantitatif dan diuji menggunakan analisis regresi linier serta analisis ordinasi. Hasil dari penelitian ini adalah menunjukkan bahwa berdasarkan uji regresi linier dan ordinasi RDA, struktur komunitas fitoplankton di perairan sekitar PLTU Paiton tidak dipengaruhi air bahang secara signifikan. Secara deskriptif kuantitatif struktur komunitas fitoplankton ini digambarkan dengan hasil keanekaragaman yang tergolong sedang (2.3026<H<6.9078) dengan nilai kelimpahan berkisar antara 7819 ind/m3 hingga 16255 ind/m3. Serta nilai keseragaman jenis labil (0.5< E ¤0.75) ditandai dengan adanya dominansi genus Oscillatoria sp. di setiap titik
Perception and satisfaction level of students regarding the teaching practices during the COVID-19 pandemic
The COVID-19 pandemic caused an unanticipated shift in the way classes were delivered. Institutions moved towards online teaching as the only way to provide lectures and laboratory work. Both instructors and students had to quickly adapt to this challenging change. The objective of this study was to examine students’ perspectives and levels of satisfaction in food-related majors regarding the teaching practices adopted. A questionnaire was created and distributed through professional networks and universities that offer food-related degrees worldwide. Participants were asked to rate their degree of satisfaction with virtual classes through a five-point Likert scale ranging from 1 «strongly disagree», 2 «disagree», 3 «neither agree nor disagree», 4 «agree» to 5 «strongly agree». Out of 388 student participants, about 49% were satisfied with the general formats of their online classes. Completing a discipline remotely took more effort than if it was taught in a face-to-face modality was felt by 66% of participants, and 56% were not motivated to attend the online classes. About 34% believed that remote learning would negatively affect their professional future, whilst 24% alleged the opposite. Additionally, about 52% of students shared that it would be better for some disciplines to be remotely taught in the future.info:eu-repo/semantics/publishedVersio
A study of a couple with type 2 diabetes: dyadic adjustment and psychological morbidity
Objective: this study assessed dyadic adjustment and psychological morbidity
in type 2 diabetic patients and their partners, focusing on the role of gender.
Methods: 214 diabetic patients and their partners participated in the cross-sectional
study and were assessed on psychological morbidity (HADS) and marital
adjustment (RDAS). Data was analyzed using dyadic analysis, a statistical process
that studies the patient/partner dyads simultaneously.
Results: results revealed that the negative relationship between dyadic adjustment
and psychological morbidity in female patients was stronger than in male
diabetic patients or in partners of male diabetic patients. On the other hand, the
relationship between dyadic adjustment and psychological morbidity in partners
of diabetic men was stronger than the same relationship in partners of diabetic
women.
Conclusion: since gender is a moderator, it is important to attend to the different
needs of female and male patients and the education of diabetic patients
should be centered on the patient/partner dyad.Fundação para a Ciência e a Tecnologia (FCT
Predictor variables and screening protocol for depressive and anxiety disorders in cancer outpatients
Background
Cancer patients are at increased risk of persistent depressive and anxiety symptoms and disorders compared to the general population. However, these issues are not always identified, which may worsen the prognosis and increase morbidity and mortality. Therefore, the objectives of this study are to identify predictor variables (demographic and clinical) for the development of mood and anxiety disorders in cancer outpatients and to propose a probabilistic screening protocol considering these variables and certain standardized screening instruments.
Methods
A total of 1,385 adults, of both genders, receiving outpatient cancer care were evaluated using a questionnaire and screening instruments. Thereafter, 400 of these subjects responded to the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (SCID-IV) by telephone to confirm or rule out the presence of a Current Major Depressive Episode (CMDE) or Anxiety Disorder (AD).
Results
Of the patients surveyed, 64% met the criteria for CMDE and 41% for AD. Female gender was found to be a risk factor for both disorders, and the presence of previous psychiatric history and marital status (divorced and widowed) were risk factors for anxiety disorders. When scoring above the recommended cutoff score, the screening instruments also indicated a risk of the studied disorders. Based on these findings, a screening protocol and nomograms were created for the quantification, combination and probabilistic estimate of risk, with accuracy indicators >0.68.
Conclusion
The prevalence rates for the disorders under study are extremely high in cancer patients. The use of the proposed protocol and nomogram can facilitate rapid and wide screening, thus refining triage and supporting the establishment of criteria for referral to mental health professionals, so that patients can be properly diagnosed and treated.info:eu-repo/semantics/publishedVersio
Time trends in prostate cancer mortality according to major geographic regions of Brazil: an analysis of three decades
Titles in Portuguese and Spanish = Tendência temporal da mortalidade por câncer de próstata segundo macrorregiões do Brasil: uma análise de três décadas = Las tendencias de la mortalidad por cáncer de próstata a través del tiempo, según las diferentes regiones brasileñas: un análisis de tres décadasThe aim of this study was to analyze prostate cancer mortality and time trends in Brazil, according to major geographic regions, States, and age brackets. Data on deaths from 1980 to 2010 were obtained from the Mortality Information System. Mortality trends were estimated using Prais-Winsten generalized linear regression. An upward time trend was observed in mortality in all regions of Brazil, with a mean annual increase of 2.8%. The upward trend in mortality occurred in most of the age brackets, with a concentration of deaths in men 70 to 79 years of age (41%) and a significant increase in the 40 to 60-year age bracket. The mortality rate increased significantly in all age brackets in the Northeast, compared to the other regions of Brazil. The study highlighted the importance of redistributing deaths from ill-defined causes in order to correct the mortality rates. The results point to significant regional differences and the need for continuous monitoring of mortality from prostate cancer in Brazil. = Analisar a distribuição e a tendência temporal da mortalidade por câncer de próstata segundo macrorregiões, Unidades Federativas (UF) e faixa etária no Brasil.

Relationship between alcohol-attributable disease and socioeconomic status, and the role of alcohol consumption in this relationship: a systematic review and meta-analysis
Background: Studies show that alcohol consumption appears to have a disproportionate impact on people of low socioeconomic status. Further exploration of the relationship between alcohol consumption, socioeconomic status and the development of chronic alcohol-attributable diseases is therefore important to inform the development of
effective public health programmes.
Methods: We used systematic review methodology to identify published studies of the association between
socioeconomic factors and mortality and morbidity for alcohol-attributable conditions. To attempt to quantify
differences in the impact of alcohol consumption for each condition, stratified by SES, we (i) investigated the relationship between SES and risk of mortality or morbidity for each alcohol-attributable condition, and (ii) where, feasible explored alcohol consumption as a mediating or interacting variable in this relationship.
Results: We identified differing relationships between a range of alcohol-attributable conditions and socioeconomic
indicators. Pooled analyses showed that low, relative to high socioeconomic status, was associated with an increased
risk of head and neck cancer and stroke, and in individual studies, with hypertension and liver disease. Conversely, risk of female breast cancer tended to be associated with higher socioeconomic status. These findings were attenuated
but held when adjusted for a number of known risk factors and other potential confounding factors. A key finding was
the lack of studies that have explored the interaction between alcohol-attributable disease, socioeconomic status and alcohol use.
Conclusions: Despite some limitations to our review, we have described relationships between socioeconomic
status and a range of alcohol-attributable conditions, and explored the mediating and interacting effects of alcohol
consumption where feasible. However, further research is needed to better characterise the relationship between
socioeconomic status alcohol consumption and alcohol-attributable disease risk so as to gain a greater understanding of the mechanisms and pathways that influence the differential risk in harm between people of low and high
socioeconomic status
Socioeconomic inequalities in expenditures and income committed to the purchase of medicines in Southern Brazil = Desigualdades socioeconomicas en los gastos y comprometimiento de la renta con medicamentos en el Sur de Brasil
Abstract published in English, Spanish and Portuguese. Article in English and Portuguese.OBJECTIVE: To describe socioeconomic inequalities regarding the use, expenditures and the income committed to the purchase of medicines. METHODS: A cross-sectional population-based study was carried out with 1,720 adults living in the urban area of Florianópolis, Southern Brazil, in 2009. Cluster sampling was adopted and census tracts were the primary sampling units. Use of medicines and the expenditures incurred in their purchase in the past 30 days were investigated through interviews. Use, expenditures and the income committed concerning medicines were analyzed according to per capita family income, self-reported skin color, age and sex, adjusting for the complex sample. RESULTS: The prevalence of medicine use was 76.5% (95%CI: 73.8; 79.3), higher among women and in older individuals. The mean expenditure on medicine was R 46,70, con valores más elevados entre las mujeres, los blancos, los de edad más elevada y entre los más ricos. Mientras que 3,1% de los más ricos comprometieron más de 15% de sus rendimientos en la compra de medicamentos, ese valor llegó a 9,6% en los más pobres. La proporción de personas que tuvieron que comprar medicamentos posterior al intento fracasado de obtenerlos por el Sistema Único de Salud fue mayor entre los más pobres (11,0%), mujeres (10,2%) y en aquellos con edad avanzada (11,1%). Gran parte de los adultos compró medicamentos ubicados en la Relación Nacional de Medicamentos Esenciales (19,9%) o en la Relación Municipal de Medicamentos Esenciales (28,6%), con diferencias significativas según sexo, edad y renta. CONCLUSIONES: Existe desigualdad socioeconómica, de edad y de género en el comprometimiento de renta con la compra de medicamentos, con peores condiciones para los más pobres, los de edad avanzada y para las mujeres.Alexandra Crispim Boing; Andréa Dâmaso Bertoldi; Karen Glazer Pere

Emerging issues and key focus areas in food science, technology, and engineering higher education
Food studies is an interdisciplinary field involving food production, distribution, consumption, and social, economic, and environmental impacts. Food science, technology, and engineering have undergone a significant transformation over the past few decades. Moreover, the food industry faces numerous critical challenges ranging from food safety, sustainability, health, and nutrition to changing consumer preferences and global food security. The food industry needs a workforce prepared for the most recent technical developments and also highly skilled. Working group 1.2, on Emerging Issued, Key Focus Areas, of IUFoST (International Union of Food Science and Technology) activities address education materials and methods on topics such as sustainability of food systems, emerging technologies, food safety, food insecurity, ethical considerations, among others. The working group organizes webinars series on teaching methods and methodologies, current critical topics in food studies, and, more recently, is opening an international web forum. This forum will promote effective communication and sharing of information in the field. It will cover topics such as curricula development, education in specific world regions, opportunities of collaboration, research education-related topics, and industry collaborations. Working group 1.2 of IUFoST is also a key element for networking with several other organizations working towards a new generation of food science, technology, and engineering professionals with the skills and knowledge required to drive innovation and reshape the industry.info:eu-repo/semantics/publishedVersio
Suicide time trends in Brazil from 1980 to 2005
Abstract and keywords in English and Portuguese. Title in Portuguese: Tendência temporal do suicídio no Brasil no período 1980-2005The aim of this study was to describe suicide time trends in Brazil from 1980 to 2005. The data were obtained from the National Mortality Information System and the Brazilian Institute of Geography and Statistics (IBGE). Suicides rates were calculated for the entire period for the country as a whole and the 26 States and Federal District. Annual increases or decreases in mortality rates were also estimated using Prais-Winsten generalized linear regression. The mean suicide rate was 4.12 per 100,000 inhabitants (6.45/100,000 in men and 1.80/100,000 in women). The study showed an increasing suicide trend in men (+1.41% per year, 95%CI: 1.00;1.23) and a decreasing trend in women (-0.53% per year, 95%CI: -0.04;-1.02). Suicide rates increased with age. In general, for all age groups and for both genders, the highest rates were in São Paulo and in the States of the South and Central-West regions. = O objetivo deste estudo foi descrever a tendência temporal das taxas de mortalidade por suicídio no Brasil, no período de 1980 a 2005. Os dados foram obtidos junto ao Sistema de Informações sobre Mortalidade e ao Instituto Brasileiro de Geografia e Estatística. Foram calculadas as taxas médias de suicídio para todo o período, para cada estado, Distrito Federal e para o país como um todo, segundo sexo e faixas etárias. Também foram calculadas as variações médias anuais do suicídio pela regressão linear generalizada de Prais-Winsten. Foi observada, no período, taxa média de suicídio de 4,12 por 100 mil habitantes, variando de 6,45 por 100 mil habitantes entre homens a 1,80 por 100 mil habitantes entre mulheres, com tendência de ascensão entre os homens (+1,41% ao ano, IC95%: 1,00;1,23) e de declínio entre as mulheres (-0,53%, IC95%: -0,04;-1,02). O suicídio aumentou com o avanço da idade em ambos os sexos. De uma maneira geral, para todas as faixas etárias e para ambos os sexos, as maiores taxas foram encontradas em São Paulo e nos estados das regiões Sul e Centro-oeste.Fabíola Stolf Brzozowski, Giovana Bacilieri Soares, Jucemar Benedet, Antonio Fernando Boing, Marco Aurélio Pere
