Published: March 2020

Abstract
Background Chronic Obstructive Pulmonary Disease (COPD) is a set of diseases, has as its main characteristics a limitation of the ventilatory flow. The World Health Organization (WHO) estimates that by 2030, COPD will be the third-largest cause of death. However, for the effective diagnosis, it is necessary to use reference curves appropriate to the population in which the individual belongs, thus it is possible to identify probable limits and abnormalities.Methods This is a cross-sectional and retrospective study conducted in a metropolitan region comprising 29 municipalities in southern Brazil. Individuals of both genders aged between 18 and 59 years, non-smokers, self-identified with white skin, participated in the study. The spirometric collections were done following the American Thoracic Society guidelines. And beyond them, mass and height were collected for determination of the Body Mass Index. The correlations between pulmonary and anthropometric variables were tested by regression analysis univariate after the selection of variables through multivariate analysis and logarithmic regression.Results In this sample, 800 participants were evaluated, of these 533 females and 267 males. Both sexes had considerable spirometry variables values as FVC, FEV6, and FEV1, used in the development of prediction models. The only variable, with a positive correlation in both genders, was height. For the males model, the best fit variable was FVC, with R 2 = 0.417 and for females FEV, with R 2 = 0.462. Among males, was seeing a lower value for all individuals in both variables. Whereas women had similar behavior, for CVS, with slight differences in the ends of the curves, comparing FEV1, the values were higher in all evaluated.Conclusion The prediction equations showed the previous curves were very restrictive and could be leading to false-positives. Thus, this update in the reference values would support clinical decisions on the prevention, diagnosis, and treatment of COPD.

Abstract
Objective: Pulmonary embolism is a terrible cardiovascular condition with considerable morbidity and mortality. Previous studies have investigated systolic blood pressure (systolic BP) and diastolic blood pressure (diastolic BP) as being related to 30-day and in-hospital mortality. We aimed to determine whether the average mean arterial pressure (aMAP) in the first 24 hours of hospital admission is useful in predicting short-term outcomes of intermediate-risk and high-risk PE patients. Method: We conducted a single-center retrospective study. From May 2012 to April 2019, 122 intermediate-risk and high-risk PE patients were included. The primary outcome was in-hospital mortality. The secondary outcome was adverse events. ROC curves and cut-off values for aMAP predicting in-hospital death were computed. According to cut-off values, we categorized five groups defined as follows: group 1: aMAP<70 mmHg; group 2: 70 mmHg≤aMAP<80 mmHg; group 3: 80 mmHg≤aMAP<90 mmHg; group 4: 90 mmHg≤aMAP<100 mmHg; and group 5: aMAP≥100 mmHg. Cox regression models were calculated to investigate associations between aMAP and in-hospital death. Results: In the study group of 122 patients, 15 patients (12.30%) died in the hospital due to PE. ROC analysis for MAP predicting in-hospital death revealed an AUC of 0.729 with a cut-off value of 79.4 mmHg. Cox regression models showed a significant association between in-hospital death and aMAP group 1 (ref), aMAP group 2 (OR 1.680, 95% CI 0.020-140.335), aMAP group 3 (OR 0.003, 95% CI 0.0001-0.343), aMAP group 4 (OR 0.006, 95% CI 0.0001-1.671), and aMAP group 5 (OR 0.003, 95% CI 0.0001-9.744). In particular, those with an aMAP of 80-90 mmHg suffer from minimum adverse events. Conclusion: The prognostic role of MAP during the first 24 hours of hospital admission should be emphasized in patients with PE. The optimal range of MAP for intermediate-risk and high-risk PE patients may be 80 to 90 mmHg.
Hairball Buster: A Graph Triage Method for Viewing and Comparing Graphs
Authors: Allen Patrick , Matties Mark , Peterson Elisha 
Published: March 2020

Abstract
Hairball buster (HB) (also called node-neighbor centrality or NNC) is an approach to graph analytic triage that uses simple calculations and visualization to quickly understand and compare graphs. Rather than displaying highly interconnected graphs as ‘hairballs’ that are difficult to understand, HB provides a simple standard visual representation of a graph and its metrics, combining a monotonically decreasing curve of node metrics with indicators of each node’s neighbors’ metrics. The HB visual is canonical, in the sense that it provides a standard output for each node-link graph. It helps analysts quickly identify areas for further investigation, and also allows for easy comparison between graphs of different data sets. The calculations required for creating an HB display is order M plus N log N, where N is the number of nodes and M is the number of edges. This paper includes examples of the HB approach applied to four real-world data sets. It also compares HB to similar visual approaches such as degree histograms, adjacency matrices, blockmodeling, and force-based layout techniques. HB presents greater information density than other algorithms at lower or equal calculation cost, efficiently presenting information in a single display that is not available in any other single display.

Published: March 2020

Abstract
In order to understand scientists’ incentives to form collaborative relations, we have conducted a study looking into academically relevant resources, which scientists contribute into collaborations with others. The data we describe in this paper are an egocentric dataset assembled by coding originally qualitative material. It is 40 multiplex ego networks containing data on individual attributes (such as gender, scientific degree), collaboration ties (including alter–alter ties), and resource flows. Resources are coded using a developed inventory of 25 types of academically relevant resources egos and alters contribute into their collaborations. We share the data with the research community with the hopes of enriching knowledge and tools for studying sociological and behavioral aspects of science as a social process.

Abstract
This study aims to explore the photocatalytic potential of graphene-oxide-based metal ferrites for the degradation of acetamiprid (an odorless neonicotinoid pesticide). Metal (Mn and Ni) ferrites (along with their graphene oxide composites) were prepared by the hydrothermal method while graphene oxide (GO) was synthesized using a modified Hummer's method. The composites were characterized by scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, and Fourier transform infrared spectroscopy. The photocatalysts were studied for their Fenton-like advanced oxidation process to degrade acetamiprid. The composites showed excellent activity against acetamiprid degradation (&gt;90%) in 60 min under UV irradiation. The detailed optimization study was carried out to investigate the influential variables (such as pH, catalyst dose, pollutant concentration, irradiation time, oxidant dose, etc.) to achieve enhanced degradation efficiency. Moreover, the findings were endorsed by central composite design (CCD). It was concluded that degradation was enhanced in an appropriate combination of photocatalyst and hydrogen peroxide. The magnetic character of the metal ferrites and their composites played an important role in the easy separation and reusability of these materials. The present findings result in highly effective, easy to handle and stable heterogeneous photo-Fenton materials for wastewater remediation.

Published: March 2020

Background:
Manipur is a small state of India, well known for its
folk medicine. Folk medicine practitioners of the state use a number of plants to
manage diabetes mellitus.

Objective:
This is an ethnomedicinal survey to find folk antidiabetic plants of the
Thoubal district of Manipur, India. This study aimed to investigate the antioxidant
and hypoglycemic potential of the chosen medicinal plant.

Methods:
An ethnomedicinal survey was carried out in Thoubal district, Manipur
to find out antidiabetic plants regularly used by tribal/folk medicinal practitioners.
Based on the information, Maesa indica leaves extracts (ethanol extract,
MIE; ethyl acetate extract, MIEA; petroleum ether extract, MIPE) were further
investigated for in vitro antioxidant and antidiabetic activity. Acute hypoglycemic
activity (streptozotocin-induced diabetes model) was evaluated and NGOGTT
tests were conducted to evaluate the hypoglycemic activity of Maesa indica
leaves.

Results:
Ethnomedicinal survey revealed that folk medicinal practitioners regularly
used 15 antidiabetic plants. Maesa indica is a plant of choice of folk medicinal
practitioners. MIE was found to possess strong oxidative haemolysis inhibition,
nitric oxide radical and DPPH radical scavenging effect with IC50 values of
54.5, 34.1 and 19.2 μg/mL, respectively. MIE inhibited α-glucosidase and α-amylase
with IC50 values of 18.2 and 31.2 μg/mL, respectively. MIE and MIEA produced
considerable hypoglycemic activity when tested through the NG-OGTT
model. MIE (500 mg/kg, b.w.) asserted significant acute hypoglycemic activity
by reducing blood glucose level after 1h, 2h, 3h, 5h, and 12h of drug administration
in streptozotocin-induced diabetic rats.

Conclusion:
The present study showed that the ethanol extract of Maesa indica
leaves possesses better activity compared to ethyl acetate and petroleum ether extract.
This study also confirmed the ethnobotanical claim about traditional use of
plant and antidiabetic potential of M. indica leaves.

Published: March 2020

Background
Using mobile technology to support health care (mobile health [mHealth]) has been shown to improve health outcomes across a multitude of health specialties and across the world. Exploring mHealth user experiences can aid in understanding how and why an intervention was successful. The Mobile Alliance for Maternal Action (MAMA) was a free maternal mHealth SMS text messaging service that was offered to pregnant women in Johannesburg, South Africa, with the goal of improving maternal, fetal, and infant health outcomes. We conducted focus group discussions with MAMA users to learn about their experiences with the program.

Objective
The aim of this qualitative study was to gather opinions of participants of the MAMA maternal mHealth service regarding health care atmosphere, intervention use, and intervention feedback.

Methods
Prenatal and postnatal women (N=15) from public antenatal and postnatal care sites in central Johannesburg who were receiving free maternal health text messages (MAMA) participated in 3 focus group discussions. Predefined discussion topics included personal background, health care system experiences, MAMA program recruitment, acceptability, participant experiences, and feedback.

Results
The feedback regarding experiences with the health system were comprised of a few reports of positive experiences and many more reports of negative experiences such as long wait times, understaffed facilities, and poor service. Overall acceptability for the maternal text message intervention was high. Participants reflected that the messages were timely, written clearly, and felt supportive. Participants also reported sharing messages with friends and family.

Conclusions
These findings suggest that maternal mHealth interventions delivered through text messages can provide timely, relevant, useful, and supportive information to pregnant women and new mothers especially in settings where there may be mistrust of the health care system.

AbstactPenulisan ini bertujuan mengkaji feneomena migrasi di Indonesia. Maraknya urbanisasi dalam artian migrasi pun menyebabkan kerugian baik untuk desa maupun untuk kota, hanya dalam waktu 20 tahun penduduk kota bertambah hampir 50%, sebaliknya setengah penduduk desa sekarang mengalami perubahan menjadi penduduk kota. Pada tahun 2005 jumlah penduduk kota sebesar 47,9% sementara pada tahun 2025 jumlah penduduk kota diprediksikan akan meningkat menjadi 68% Meningkatnya urbanisasi membuat kemiskinan terkonsentrasi di kota,akan tetapi hal ini terjadi karena adanya pandangan masyarakat desa bahwa kota merupakan harapan nyata dalam memutus rantai kemiskinan kemiskinan. Terjadinya migrasi diperkotaan atau ( urbanisasi) tidak akan menjadi masalah jika pemerintah dari kota-kota tujuan para migran mampu menciptakan lapangan kerja dan fasilitas publik yang mencukupi. Namun bila saja daya dukung kota sebagai suatu tempat publik sudah berada pada level yang kritis , maka pememrintah melalui berbagai macam kebijakannnya perlu turun tangan guna mengurangi dampak buruk dari urbanisasi tersebut. Urbanisasi berlebih perlu dikendalikan agar tidak berkembang makin liar dan semakin membebani kota-kota tujuan kaum migran.Kata kunci: Fenomena, Migrasi, Urban BiasThe Study purpose to discuss the migration phenomenon in Indonesia. The rise of urbanization in the sense of migration also causes losses both for villages and for cities, in just 20 years increased by almost 50%, on the contrary half the village population is now becoming residents of the city. In 2005 the population of the city was 47.9% while in 2025 the population of the city was predicted to increase to 68%. Increased urbanization made poverty concentrated in the city, but this happened because of the view of the village community that the city represented the best hope for getting out of poverty. The occurrence of urban migration or (urbanization) will not be a problem if the government of the destination cities of migrants is able to create adequate employment and public facilities. But if the carrying capacity of the city as a public place is at a critical level, the government through various policies needs to intervene to reduce the adverse effects of urbanization. Excessive urbanization needs to be controlled so that it does not grow wilder and increasingly burden cities of migrants.Key words: Phenomenon, Migration, Urban Bias
