    Objective: Neonatal asphyxia accounts for a quarter of neonatal deaths. We aimed to assess factors associated with mortality among asphyxiated neonates in a low-resource setting. Methods: A retrospective observational study evaluating all neonates who were admitted for asphyxia to the Neonatal Intensive Care Unit (NICU) at Tosamaganga Hospital (Tanzania) in 2017–2018. Inclusion criteria were: Apgar score <7 at 5 min and/or failure to initiate spontaneous breathing and/or presence of sentinel events and/or clinical signs suggesting encephalopathy not explained by other obvious factors or early convulsions. Newborns with congenital malformations, birth weight <2000 g or those who died in the delivery room were excluded. Results: NICU admission for perinatal asphyxia was 17.5%. In 169 neonates, mortality rate was 23% and was associated with being outborn, low 5-minute Apgar score, depressed clinical status at NICU admission, occurrence of infection or seizures within 24 h from admission, and receiving aminophylline during the hospital stay. Conclusions: Perinatal asphyxia was responsible for a relevant proportion of NICU admissions and neonatal deaths in a low-resource setting. Appropriate clinical examination remains the main asset in settings with limited availability of diagnostic tools. Improvements in antenatal and perinatal care are needed to reduce mortality in asphyxiated newborns. Future studies should assess long-term outcome in survivors

    Aim: Quality improvement approaches have been integrated into routine health care in high-resource settings, but not in low-resource settings. We aimed to report the achievements in maternal and neonatal care after a quality improvement intervention in a sub-Saharan setting. Methods: After a first quality assessment in 2012 at Tosamaganga hospital in Tanzania, main areas of intervention were identified and a quality improvement program was implemented. In 2016, a second quality assessment was conducted by the same assessment team by using the World Health Organization’s maternal and neonatal quality of hospital care assessment tool. Some hospital indicators were also collected during the same period. Results: Access to hospital care, maternity ward and management of maternal complications improved from inadequate to substandard care, alongside with an increment of deliveries from 2145 to 2838 and a substantially stable rate of complicated deliveries (21–26%). The improvements in the maternity ward, maternal complications and emergency care coupled with the reduction of direct obstetric case fatality rate obstetric mortality that dropped from 2.9 to 0.27%. Some neonatal areas (neonatal ward, routine neonatal care, sick newborn care, monitoring, and follow-up) improved from poor to substandard care, while others (infection control and supportive care, emergency care, guidelines protocols, and audit) showed only limited improvements. These changes coupled with a decrease in the perinatal mortality rate from 5.8 to 2.9%. Conclusion: The quality improvement program resulted in substantial progress in most aspects of quality care, which coupled with a decrease in obstetric and perinatal mortality. Nevertheless, the overall quality of care remained substandard with the limited effect of the intervention on some areas, which require further efforts in order to achieve an acceptable level of care

    Analysis of caesarean section and neonatal outcome using the Robson classification in a rural district hospital in Tanzania: An observational retrospective study

    OBJECTIVE: Caesarean section (CS) rates have increased worldwide in recent decades. In 2015, the WHO proposed the use of the 10-group Robson classification as a global standard for assessing, monitoring and comparing CS rates both within healthcare facilities over time and between them. The aim of this study was to assess the pattern of CS rates according to the Robson classification and describe maternal and perinatal outcomes by group at the Tosamaganga Hospital in rural Tanzania. DESIGN: Observational retrospective study. SETTING: St. John of the Cross Tosamaganga Hospital, a referral centre in rural Tanzania. PARTICIPANTS: 3012 women who gave birth in Tosamaganga Hospital from 1 January to 30 June 2014 and from 1 March to 30 November 2015. RESULTS: The overall CS rate was 35.2%, and about 90% of women admitted for labour were in Robson groups 1 through 5. More than 40% of the CS carried out in the hospital were performed on nulliparous women at term with a single fetus in cephalic presentation (groups 1 and 3), and the most frequent indication for the procedure was previous uterine scar (39.2%). The majority of severe neonatal outcomes were observed in groups 1 (27.7%), 10 (24.5%) and 3 (19.1%). CONCLUSION: We recorded a high CS rate in Tosamaganga Hospital, particularly in low-risk patients groups (Robson groups 1 and 3). Our analysis of Robson classification and neonatal outcomes suggests the need to improve labour management at the hospital and to provide timely referrals in order to prevent women from arriving there in critical conditions

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Variations on the Author

    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Appropriate Similarity Measures for Author Cocitation Analysis

    Full text link
    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

    Dispelling the Myths Behind First-author Citation Counts

    Full text link
    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    No full text
    We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
