Analysis of Sci-Hub downloads of computer science papers

Abstract The scientific knowledge is disseminated by research papers. Most of the research literature is copyrighted by publishers and avail- able only through paywalls. Recently, some websites offer most of the recent content for free. One of them is the controversial website Sci-Hub that enables access to more than 47 million pirated research papers. In April 2016, Science Magazine published an article on Sci-Hub activity over the period of six months and publicly released the Sci-Hub’s server log data. The mentioned paper aggregates the view that relies on all downloads and for all fields of study, but these findings might be hiding interesting patterns within computer science. The mentioned Sci-Hub log data was used in this paper to analyse downloads of computer science papers based on DBLP’s list of computer science publications. The top downloads of computer science papers were analysed, together with the geographical location of Sci-Hub users, the most downloaded publishers, types of papers downloaded, and downloads of computer science papers per publication year. The results of this research can be used to improve legal access to the most relevant scientific repositories or journals for the computer science field.
COMPREHENSIVE MANAGEMENT AND ANALYSIS OF COMPLEX AND LARGE RESEARCH DATASETS: AN APPLICATION IN COMMUNICATION SCIENCE AND DISORDERS

Today, healthcare is awash in data. With the increasing number of data resources and advancements in information technology, large and complex research datasets are at hand to be used and converted into knowledge, which is one critical driver in our journey toward effective, efficient, and safe healthcare. However, when these datasets are mismanaged or corrupted, they could produce low-quality and even misleading results. Thus, it is critical to maintain high quality standards of data management and promote for the concepts of data lifecycle and data curation due to their direct impact on the quality of research datasets. This dissertation research is aimed at demonstrating a data management and quality assurance process through the implementation of a full research dataset lifecycle, building a centralized and secured database with a user-friendly interface and assess its usability, and testing a theory-based model of sentence comprehension using structural equation modeling for four types of sentences. Results of this study have shown that automating the process of extracting, verifying, transforming, and storing large research datasets from their source files to a structured and analysis-friendly database increases the quality of the data, reduces the burden and time waste of researchers, and facilitates communications between the research team members. The conducted usability study has shown that users spend less time and make fewer errors when retrieving datasets using properly designed interfaces than using spreadsheets. Results from the sentence comprehension analysis have shown that language processing, short-term memory, and working memory can be measured separately. The structural equation modeling analyses have also shown the importance of working memory and how it significantly predicts sentence comprehension of object cleft and garden path sentences. The data processing techniques used in this dissertation have laid the cornerstone of a generic data processing and management system that gives clinical researchers, especially the ones with limited resources, the ability to manage and process their datasets by enabling them to define and execute different extraction rules. The results of the dissertation also provided clarification on the nature of the interactions between critical cognitive systems and their impact in sentence comprehension deficits.
Nutrition risk and validation of an HIV disease-specific nutrition screening tool in Ghana

Objectives: The objectives of this study were to assess the nutritional status and the most commonly reported nutrition-related factors contributing to nutritional risk in people living with HIV/AIDS (PLWHA) in Ghana and the specificity and sensitivity of the Rapid Nutrition Screening for HIV disease tool (RNS-H) in this population. Design: A cross-sectional design was utilised. Patients were screened for nutritional status during a one-week period by clinic nurses using the RNS-H. Results were compared with a comprehensive nutritional assessment by a dietitian. Setting: The research was conducted in a public health clinic at the University of Ghana Hospital, Legon. Subjects Patients receiving care at the clinic were asked to participate. Outcome measures: The nutritional screening and nutritional assessment both resulted in participants being assigned to one of three nutritional statuses: ‘low risk’, ‘at risk’ and ‘high risk’. The association between the nutritional screening and nutritional assessment was measured. Results: The results of the nutritional status assigned by the RNS-H and nutritional assessment were compared. A total of 51 patients participated. A high prevalence of nutritional risk based on the RNS-S (54.9%) was found with 33.3% of the sample being malnourished. The most common nutrition-related complications were food insecurity, poor appetite, weight loss and diarrhoea. Conclusions: The RNS-H was found to have a strong specificity and sensitivity in a sample of Ghanaian PLWHA. Because of the nutritional risk and complexity of HIV in Ghana, nutritional screening using the RNS-H and nutrition care by a dietitian should be a standard of care.
Path Analysis on the Biological and Social-Economic Determinants of Anemia in Pregnant Mothers in Bantul, Yogyakarta

Background : Anemia in pregnant women is one of the public health problems that is still considered as a serious problem. The most important things in handling cases of anemia in pregnant women is to pay attention to biological and socio-economic factors in pregnant women. This study aimed to determine the effect of biological and socio-economic factors on the incidence of anemia among pregnant women. Subjects an d Met h od: This was a cross sectional study conducted in Bambanglipuro community health center, Bantul, Yogyakarta, from March to April 2019. A sample of 200 pregnant women was selected by fixed disease sampling. The dependent variable was anemia. The independent variables were age, gestational age, parity, birth spacing, education, income, adherence to iron tablet consumption, contraceptive use before pregnancy, dietary pattern, and body mass index (BMI). The data were collected by questionnaire and analyzed by path analysi s . Result s: The risk of anemia in pregnant women was directly and positively affected by education <Senior high school (b=1.92; 95% CI=0.67 to 3.17; p=0.003), age <20 or ≥35 years old (b=1.27; 95% CI= 0.09 to 2.46; p=0.036), parity ≥3 times (b=1.57; 95% CI= 0.42 to 2.72; p=0.007), birth spacing <2 years (b=2.58; 95% CI= 1.23 to 3.93; p<0.001), gestational age (II and III trimesters) (b=2.07; 95% CI=0.69 to 3.45; p=0.003), BMI <18.5 (b=3.21; 95% CI=1.98 to 4.44; p<0.001), and irregular iron tablet consumption (b=1.46; 95% CI=0.31 to 2.62; p=0.013). It was indirectly affected by education, history of contraceptive use, dietary pattern, and family income. Conclusion : The risk of anemia in pregnant women is directly and positively affected by education <Senior high school, age <20 or ≥35 years old, parity ≥3 times, birth spacing <2 years, gestational age (II and III trimesters), BMI <18.5, and irregular iron tablet consumption. It is indirectly affected by education, history of contraceptive use, dietary pattern, and family income.

Did drug availability in Malawian central hospitals improve after the conversion of central medical stores to a trust

Malawian public hospitals have reportedly been experiencing a lot of shortages in medicines and medical supplies in recent years. This was at least in part, attributed to the traditional placement of the drug supply system under the Ministry of Health, and therefore a change in the organizational set-up was implemented in 2011. This study aimed at finding out if the availability of medicines in central hospitals in Malawi improved after the change of Central Medical Stores (CMS) to a Trust (CMST). A retrospective cohort study was done to quantify the availability of selected essential medicines before and after the change of CMS from stock cards. A questionnaire was filled by 23 health professionals to assess their views on whether the change of CMST resulted in improved availability of medicines. The study was done at Queen Elizabeth Central Hospital (QECH), Kamuzu Central Hospital (KCH) and Central Medical Store Trust. The targeted study period was before the change of CMS (2010/2011) and after (2013/2014) the change to CMST. The results of the study showed considerable reduction in stock-out days for both KCH and the CMST (from an average of 80 and 16 days to 42 and 9 days, respectively), with CMST results being statistically significant (p=0.023). However, in QECH, there was no improvement (from 22 to 24 days). The view of most respondents was that there was no improvement in medicine availability after the change of CMS, which represented a certain contradiction to the results of the quantitative part. This may be attributed to the fact that the questionnaire targeted only participants from QECH and KCH and left out participants from CMST. The study indicated that the radical shift in the management of CMS was followed by an improvement of drug availability in CMST itself, and in one of the two investigated hospitals. The non-improvement in drug availability in hospitals calls for further investigation in the future to understand the reasons for this. Key words: Central medical stores, Malawi, medicine availability, essential medicine, autonomous supply agency, pharmaceutical logistics, supply chain.
Methylenetetrahydrofolate reductase (MTHFR) C677T and A1298C polymorphisms in breast cancer: a Sardinian preliminary case-control study

Two common polymorphisms in the MTHFR gene, C677T and A1298C, are associated with reduced enzyme activity and may be associated with breast cancer susceptibility. We performed a case-control study to investigate the association between the two SNPs in the MTHFR gene and risk of breast cancer. In total, 58 breast cancer patients and 58 unaffected controls were enrolled in the study. Polymerase chain reaction/restriction fragment length polymorphism technique (PCR-RFLP) was conducted to determine the genotypes. No significant differences were found in the genotypes of the two polymorphisms of the MTHFR gene between cases and controls. The OR and 95% CI for the 677CC, 677CT and 677TT genotypes were 1.00, 0.95 (0.39-2.31) and 0.87 (0.27-2.80), respectively; those of the 1298AA, 1298AC and 1298CC genotypes were 1.00, 0.59 (0.26-1.36) and 0.78 (1.32-4.66) respectively. Furthermore, it has been shown in patients with breast cancer a risk of presenting with an aggressive biophenotype about twice or three times higher in the presence of the C677T and A1298C polymorphisms, respectively. Finally, the A1298Cpolymorphism is significantly associated with increased recurrence risk of lymph node-positive breast cancer. Our study has not shown a significant association between MTHFR gene polymorphisms and breast cancer risk. However, it highlighted the key-role played by the presence of mutant alleles for both polymorphisms in increasing the risk of developing more aggressive phenotypes; moreover, specifically in A1298C, it might also lead to a higher risk of developing lymph node metastasis.
Study Protocol: 6th National Survey of Australian Secondary Students and Adolescent Sexual Health, 2018

Introduction: Since 1992 the Australian Government has funded a periodic national survey of HIV and Sexually Transmissible Infection (STI) knowledge and sexual risk behavior among secondary school students. Adolescents continue to be a priority population in public health efforts to reduce rates of STIs in Australia. The purpose of the survey is to inform progress on national strategic sexual health priorities. The results are used by federal and state/territory government agencies, youth-serving community organizations and health educators to improve knowledge, promote healthy sexual behaviors and target educational efforts aimed at communicating public health messages to young people. Materials and Equipment: The 6th survey entitled the “National Survey of Secondary Students and Adolescent Sexual Health” was conducted online in 2018 among 14–18 year olds living in Australia. The anonymous self-complete survey contained up to 286 items assessing three primary domains of knowledge, behaviors and education experiences. Factual knowledge measures covered HIV transmission and STI knowledge around transmission and prevention covering gonorrhea, Chlamydia, syphilis, hepatitis, herpes, and HPV. Behavioral measures examined perceived susceptibility, peer norms, protective behaviors, age of onset for various behaviors, reasons for not being sexually active yet, and/or sexual histories with additional detail on most recent sexual event. The 6th survey was completed by 8,400 Australian adolescents a represents a broad cross-section by age, gender, year in school, type of school (e.g., government, Catholic), and state/territory which closely matched census data on these strata. The one-of-a-kind survey instrument, grounded in public health theories, may prove valuable for public health researchers. Expected Impact of the Study on Public Health: Findings from the 6th National Survey of Secondary Students and Adolescent Sexual Health will contribute important insights into current knowledge, behaviors and educational experiences of young people. Results, similar to previous iterations of the survey, will inform public health practitioners, policymakers, educators, and advocates for the sexual health and well-being of young Australians. Results may assist sexual health services to align with broader public health goals articulated in the national HIV and STI strategies aimed to reduce the burden of disease and improve the quality of sexual lives of young Australians.
Clinical profile and outcome of patients admitted with swine-origin Influenza A H1N1 virus infection at a tertiary care hospital in Western India

Background: Most of the studies on swine flu H1N1 have been done during the pandemic phase. There was a sudden upsurge in virus activity in 2015 at many centers in India. The present study was designed to assess the current status and pattern of H1N1 infection. The primary objective of this study is to study the clinical profile of patients admitted with Swine-origin influenza A (H1N1) virus infection and Secondary objective is to study the clinical outcome in terms of morbidity and mortality.Methods: This was a retrospective observational study done at a tertiary care centre from March 2015 to April 2016. All admitted and confirmed cases of H1N1 swine flu infection were studied for demographic details, co-existing medical conditions and clinical presentation. Data regarding the course of disease, complications, treatments and outcomes were recorded from the clinical record.Results: Common presenting symptoms were cough and fever (95%). Common findings were fever (62.5%), tachycardia, tachypnea and crepitation on auscultation (58.5%). Associated comorbidities were Diabetes mellitus (19.5%), Chronic kidney disease (17%), immunosuppression (9.8%). Consolidation was seen in nearly half of the patients on radiological imaging. Complications noted in our patients were pneumonia (45%), respiratory failure (31%) and ARDS (14.6%). Seventeen percent of patients required non-invasive and invasive mechanical ventilation. Around 25 percent of cases, required ICU admission while two patients died during the hospital stay.Conclusions: The study emphasizes and restates the morbidities caused by H1N1 swine influenza infection as nearly half of the patients in this study experienced severe illness and complications.

Renin-angiotensin-aldosterone System Blockers, Hypertension, and Clinical Outcomes

Our knowledge of the RAAS started in 1898 when Tigerstedt and Bergman showed that renal extract from rabbits increased BP when infused and named it as renin. [1] In 1934, Goldblatt demonstrated that renal artery constriction caused renal ischemia and induced hypertension (HTN) in dogs. Later, in 1939–1940, Braun-Menende in Argentina and Page and Helmer in the USA simultaneously discovered a pressor substance capable of causing renal HTN. This was originally named hypertensin in Argentina and angiotonin in the USA and later renamed as angiotensin to give credit to both groups. [1] The discovery of captopril, an orally active Ang-converting enzyme inhibitor (ACE-I) in 1980 and Ang receptor blockers (ARBs) in 1998, went on to revolutionize medical care.

Newborns bilirubin concentration determined by different methods in relation to hematocrit and albumin level

Background Monitoring of bilirubin is essential during early neonatal life. Bilirubin in high concentration is toxic to the brain and might cause irreversible neurological damage. Several different methods for bilirubin determination are available nowadays, but inconsistent results may be obtained. The study aimed to compare dry chemistry methods with vanadate oxidation method for bilirubin determination in relation to hematocrit and albumin level in neonates and infants. Methods The study included 98 consecutive serum samples from newborns and infants (47 boys and 51 girls, mean age 19 ± 15 days) treated in the University Children's Hospital in Krakow. Total bilirubin (TBil) and neonatal bilirubin (NBil) concentration were measured by dry chemistry analyser (Vitros 4600, Ortho Clinical Diagnostics Inc.). Total bilirubin (TBilV) was also measured using vanadate oxidation method (Cormay, Poland). Albumin concentration and blood morphology have been routinely determined in all children. Results No significant differences between the mean value of NBil (69.00 ± 67.76 μmol/L), TBil (81.26 ± 70.13 μmol/L) and TBilV (75.90 ± 60.62 μmol/L) were noticed. High coefficient correlation between NBil and TBil as well as between NBil and TBilV were noticed (Pearson's analysis, r = 0.99, r = 0.97, respectively; p < 0.0001 in both cases). There was a positive correlation between the difference (TBilV - NBil) and hematocrit (p < 0.009, r = 0.2664). Conclusions In newborns and infants the same method for bilirubin determination should be used when the concentration of bilirubin is monitored. When using vanadate oxidation method for bilirubin determination, hematocrit value should be taken into account when results are interpreted.
Assessing the Quality of Care Provided to Older Persons with Frailty in Five Canadian Provinces, Using Administrative Data

RÉSUMÉ Nous avons examiné la qualité des soins fournis aux personnes âgées fragiles dans cinq provinces canadiennes à partir de données administratives sur la santé. Dans chaque province, nous avons considéré les personnes âgées fragiles en fonction de deux cohortes : les personnes décédées et les personnes vivantes. Des règles de décision ont été utilisées pour déterminer quelles personnes étaient frêles, soit celles résidant en établissement de soins de longue durée, qui étaient en phase terminale ou dont le profil correspondait à deux des sept domaines identifiés. Ces domaines étaient fondés sur des échelles de fragilité, des discussions avec des gériatres et des indicateurs d’utilisation des services de santé. Nous avons évalué la qualité des soins à l’aide des indicateurs de qualité suivants : diminution de la durée de l’hospitalisation, diminution du nombre de réadmissions à l’hôpital, diminution du nombre de visites à l’urgence, augmentation de la continuité des soins fournis par un médecin de famille, diminution de l’utilisation de la ventilation mécanique et diminution du nombre d’admissions aux soins intensifs. À l’aide d’analyses de régression, nous avons également constaté que le sexe masculin et l’âge avancé étaient associés à une moins bonne qualité de soins dans les deux cohortes. Cette étude fournit des données de base qui permettront d’évaluer les futurs efforts visant à améliorer la qualité des soins offerts aux personnes âgées fragiles. ABSTRACT We examined the quality of care provided to older persons with frailty in five Canadian provinces, using administrative health data. In each province, we identified two cohorts of older persons with frailty: decedents and living persons. Using decision rules, we considered individuals to be frail if they were long-term care residents, terminally ill, or met at least two of seven domains, which were based on frailty scales, geriatrician discussions, and health service utilization indicators. We assessed quality of care using selected quality indicators: decrease in length of hospital stay, decrease in the number of in-patient readmissions, decrease in the number of emergency department visits, increase in the level of family physician continuity of care, decrease in the use of mechanical ventilation, and decrease in the number of admissions to intensive care. Using regression analyses, we also found male sex and older age were associated with poorer quality of care in both cohorts. This study provides baseline data for evaluating future efforts to improve the quality of care provided to older persons with frailty.
Root coverage stability with acellular dermal matrix in multiple gingival recessions in esthetic zone: A clinical case report with 12-year follow-up

The importance of surgical intervention for the maintenance of long-term results by root coverage of multiple gingival recessions in an esthetic area treated with a tissue substitute (acellular dermal matrix [ADM]-Alloderm®) is widely required. The present case report highlights the effectiveness of the ADM for the treatment of multiple recession defects in a female patient with Class I and II gingival recession in relation to maxillary anterior associated with esthetics and dentin hypersensitivity demands. The root coverage rate for the anterior area showed greater value with 70% of coverage; at 90 days and 2 and 12 years of follow-up, it showed 70.5%, 79%, and 77%, respectively. Conversely, for the posterior area, these rates were 68.5%, 63%, and 57% for the same follow-up periods. Results regarding gain of keratinized tissue demonstrated superior values for the anterior area, namely 3.92, 3.34 and 3.22 mm at 90 days and 2 and 12 years. These values for the posterior area were 0.54 mm, 2.41, and 1.87 mm, respectively. These findings suggest that the tissue substitute Alloderm® showed excellent long-term results for areas of multiple recessions, providing root coverage and stability of keratinized tissue gain. After this long period of evaluation, some local factors associated with recurrence of gingival recessions were detected, and a lack of proper periodontal maintenance care was observed. However, esthetic and functional outcomes achieved with surgical procedure were maintained.
