Thermophysical Properties of Shoe Polish Manufactured from Pure Water Sachet

The thermophysical properties of shoe polish manufactured from wastewater sachet was investigated. Wastewater sachet was pyrolyzed at various temperatures to obtain wax yield. The other types of wax obtainable were discussed. A formulation is developed with the wax generated. Shoe polish is made from the paraffin wax obtained from the thermal decomposition of pure water sachet in a reactor. This recovery process helps in the disposing of what was hitherto a waste thereby reducing environmental pollution. The recovered product is tested for its thermophysical properties such as density, viscosity pour point and melting point. These properties were compared with a foreign manufactured shoe polish. The highest wax yield was obtained at a temperature of 160°C yielding 59.8g in 12 min

Making It Happen: Training health-care providers in emergency obstetric and newborn care

An estimated 289,000 maternal deaths, 2.6 million stillbirths and 2.4 million newborn deaths occur globally each year, with the majority occurring around the time of childbirth. The medical and surgical interventions to prevent this loss of life are known, and most maternal and newborn deaths are in principle preventable. There is a need to build the capacity of health-care providers to recognize and manage complications during pregnancy, childbirth and the post-partum period. Skills-and-drills competency-based training in skilled birth attendance, emergency obstetric care and early newborn care (EmONC) is an approach that is successful in improving knowledge and skills. There is emerging evidence of this resulting in improved availability and quality of care. To evaluate the effectiveness of EmONC training, operational research using an adapted Kirkpatrick framework and a theory of change approach is needed. The Making It Happen programme is an example of this

Humanising the Dehumanised: Collective Pedagogy in Nwamuo’s The Prisoners

The question of a convenient equipoise between the artist and his immediate society has for long dominated the field of sociology of literature. This has become increasingly unavoidable in dictatorial regimes. For leftist writers, the basic essence is to ‘unsettle’ the already settled and indeed defeatist or fatalistic mindsets of the oppressed class. Consequently, the essence of the education their literature offers is towards the goal of liberation: indeed, the practice of freedom is central to this theory of action. In this wise, the paper is a study of The Prisoners, a play written by one of Nigeria’s second generation playwrights. The paper observes that our chosen playwright belongs to the Left and he adopts the principle of collective pedagogy, which involves collective teaching and thinking through together among the vectors of revolutionary change. Again, it is observed that the playwright’s personal experience of the Nigerian Civil War (1967-1970) coupled with his working experiences and social rapport with the rulers and the ruled in Nigeria or elsewhere may have conditioned his conceptualisation of the play. Thus, the essence of investigating Nwamuo’s The Prisoners is to highlight the implications of collective pedagogy in enhancing social change and development in the society.Keywords:  Humanising; Dehumanised; collective pedagogy; freedom, humanity Résumé:  Toutes les sociétés humaines, quelle que soit son apparence primitive, est régie par un code de lois. Ces lois donnent un ordre et un sens à leur vie et servent de contrôle social et du développement global de la société. Certaines sociétés négligent les droits naturels et civils de leurs citoyens, en particulier les femmes et les enfants, parce qu'elles pensent que les droits des femmes et des enfants sont suffisamment protégés par leurs maris et leurs pères. Mais les traitements inhumains infligés aux femmes et aux enfants, voire par leurs maris et les pères ont mis en évidence les erreurs et les problèmes de considérer que les droits des femmes et des enfants dans la société sont protégés. Le présent article examine donc les dangers posés de considérer les droits des enfants comme acquis dans la société et les efforts déployés au Nigeria, à fin de protéger l'enfant pour un développement global et durable de la société.Mots-clés:  enfants, droits; droit de survie; droit de development; droit de participation; droit de protectio

The effectiveness of emergency obstetric care training in Kenya

Background and introduction Maternal deaths are highest in low resource countries, skilled attendance at birth (SBA) and the availability of emergency obstetric care (EmOC) are key strategies to improve maternal health and achieve the millennium development goal number 5. In-service emergency obstetric and newborn care (EmONC) training has been used for many years to improve the quality of skilled attendance at birth and availability of EmOC, however few packages have been properly described and evaluated. There is no published comprehensive evaluation of EmONC in-service training packages in low resourced countries. An evaluation of the effectiveness of an EmONC training intervention in 10 comprehensive EmOC Kenya hospitals was carried out from 2010-2011. Methods A systematic review was performed based on grading of recommendations assessments development and evaluation (GRADE) guidelines to identify the various EmONC training packages in low and middle income countries, identify literature on the effectiveness of these packages or effectiveness of various components of EmONC training globally. The components of the intervention were training in EmONC, provision of EmOC equipment and supportive supervision. The objective of the intervention was to improve the recognition and treatment of emergency obstetric and newborn complications at all study sites by trained maternity care providers (MCP). A before/after study design and an adapted four level Kirkpatrick framework (level 1: reaction to training, level 2: learning, level 3: behaviour/practice, level 4: EmOC availability, health outcomes and ‘up-skilling’) was used to evaluate the effectiveness of the training package. Mixed research methods (quantitative and qualitative approaches) were used to collect data 3 months before the intervention and at 3 monthly intervals after up to 12 months after the intervention. Quantitative data were analysed using SPSS version 20 and qualitative data was analysed using Nvivo 9. Descriptive statistics and analysis using t-tests were performed for quantitative data (significance in mean difference at 95% confidence) while framework analysis was used for qualitative data. Results 20 EmONC in-service training programmes implemented in low and middle-income countries were identified. The content of 85% (17) of the programmes identified included EmOC signal functions and 7 programmes were 7 days or more in duration. 50% (10) of the EmONC training packages identified had training reports of which only two studies were evaluated at Kirkpatrick level 3 (behaviour) and there was no evaluation at level 4 (health outcomes) identified. Over 70% of all identified maternity care providers from all 10 hospitals were trained. 83% (328) of the 400 health care workers trained were midwives, 6% (26) were medical doctors, 2% (8) were clinical officers and 3% (11) were obstetricians. At 12 months post training the proportion of MCP trained in each hospital was at least 83% except for Nakuru PGH (23%) and Mbagathi GH (50%). Kirkpatrick level 1: About 95% (380) participants responded to level 1 assessment questionnaire. Trainees reacted positively to all lectures (n=11, mean score was 9.38/100, SD: 0.12) and breakout sessions (n=25, mean score was 9.33/10, SD: 0.14). Kirkpatrick level 2: There was a statistically significant difference between the pre and post training knowledge scores in all modules except preventing obstructed labour 0.10 CI (0.06-0.26) p=0.201. The mean difference between pre and post-test skill scores was statistically significant 3.5 CI (3.3-3.8)

Development and validation of an obstetric early warning system model for use in low resource settings

Background The use of obstetric early-warning-systems (EWS) has been recommended to improve timely recognition, management and early referral of women who have or are developing a critical illness. Development of such prediction models should involve a statistical combination of predictor clinical observations into a multivariable model which should be validated. No obstetric EWS has been developed and validated for low resource settings. We report on the development and validation of a simple prediction model for obstetric morbidity and mortality in resource-limited settings. Methods We performed a multivariate logistic regression analysis using a retrospective case-control analysis of secondary data with clinical indices predictive of severe maternal outcome (SMO). Cases for design and validation were randomly selected (n = 500) from 4360 women diagnosed with SMO in 42 Nigerian tertiary-hospitals between June 2012 and mid-August 2013. Controls were 1000 obstetric admissions without SMO diagnosis. We used clinical observations collected within 24 h of SMO occurrence for cases, and normal births for controls. We created a combined dataset with two controls per case, split randomly into development (n = 600) and validation (n = 900) datasets. We assessed the model’s validity using sensitivity and specificity measures and its overall performance in predicting SMO using receiver operator characteristic (ROC) curves. We then fitted the final developmental model on the validation dataset and assessed its performance. Using the reference range proposed in the United Kingdom Confidential-Enquiry-into-Maternal-and-Child-Health 2007-report, we converted the model into a simple score-based obstetric EWS algorithm. Results The final developmental model comprised abnormal systolic blood pressure-(SBP > 140 mmHg or  90 mmHg), respiratory rate-(RR > 40/min), temperature-(> 38 °C), pulse rate-(PR > 120/min), caesarean-birth, and the number of previous caesarean-births. The model was 86% (95% CI 81–90) sensitive and 92%- (95% CI 89–94) specific in predicting SMO with area under ROC of 92% (95% CI 90–95%). All parameters were significant in the validation model except DBP. The model maintained good discriminatory power in the validation (n = 900) dataset (AUC 92, 95% CI 88–94%) and had good screening characteristics. Low urine output (300mls/24 h) and conscious level (prolonged unconsciousness-GCS < 8/15) were strong predictors of SMO in the univariate analysis. Conclusion We developed and validated statistical models that performed well in predicting SMO using data from a low resource settings. Based on these, we proposed a simple score based obstetric EWS algorithm with RR, temperature, systolic BP, pulse rate, consciousness level, urinary output and mode of birth that has a potential for clinical use in low-resource settings.

Early warning systems in obstetrics: A systematic literature review

Introduction Several versions of Early Warning Systems (EWS) are used in obstetrics to detect and treat early clinical deterioration to avert morbidity and mortality. EWS can potentially be useful to improve the quality of care and reduce the risk of maternal mortality in resource-limited settings. We conducted a systematic literature review of published obstetric early warning systems, define their predictive accuracy for morbidity and mortality, and their effectiveness in triggering corrective actions and improving health outcomes. Methods We systematically searched for primary research articles on obstetric EWS published in peer-reviewed journals between January 1997 and March 2018 in Medline, CINAHL, SCOPUS, Science Direct, and Science Citation Index. We also searched reference lists of relevant articles and websites of professional societies. We included studies that assessed the predictive accuracy of EWS to detect clinical deterioration, or/and their effectiveness in improving clinical outcomes in obstetric inpatients. We excluded studies with a paediatric or non-obstetric adult population. Cross-sectional and qualitative studies were also excluded. We performed a narrative synthesis since the outcomes reported were heterogeneous. Results A total of 381 papers were identified, 17 of which met the inclusion criteria. Eleven of the included studies evaluated the predictive accuracy of EWS for obstetric morbidity and mortality, 5 studies assessed the effectiveness of EWS in improving clinical outcomes, while one study addressed both. Sixteen published EWS versions were reviewed, 14 of which included five basic clinical observations (pulse rate, respiratory rate, temperature, blood pressure, and consciousness level). The obstetric EWS identified had very high median (inter-quartile range) sensitivity—89% (72% to 97%) and specificity—85% (67% to 98%) but low median (inter-quartile range) positive predictive values—41% (25% to 74%) for predicting morbidity or ICU admission. Obstetric EWS had a very high accuracy in predicting death (AUROC >0.80) among critically ill obstetric patients. Obstetric EWS improves the frequency of routine vital sign observation, reduces the interval between the recording of specifically defined abnormal clinical observations and corrective clinical actions, and can potentially reduce the severity of obstetric morbidity. Conclusion Obstetric EWS are effective in predicting severe morbidity (in general obstetric population) and mortality (in critically ill obstetric patients). EWS can contribute to improved quality of care, prevent progressive obstetric morbidity and improve health outcomes. There is limited evidence of the effectiveness of EWS in reducing maternal death across all settings. Clinical parameters in most obstetric EWS versions are routinely collected in resource-limited settings, therefore implementing EWS may be feasible in such settings

Early indirect impact of COVID-19 pandemic on utilisation and outcomes of reproductive, maternal, newborn, child and adolescent health services in Kenya: A cross-sectional study

The paper determined the initial impact of COVID-19 pandemic on reproductive, maternal, newborn, child and adolescent health (RMNCAH) services in Kenya. Hospital data for the first four months (March-June 2020) of the pandemic and the equivalent period in 2019 were compared using two-sample test of proportions. Despite the global projections for worse indicators, there were no differences in monthly mean (±SD) attendance between March-June 2019 vs 2020 for antenatal care (400,191.2±12,700.0 vs 384,697.3±20,838.6), hospital births (98,713.0±4,117.0 vs 99,634.5±3,215.5), family planning attendance (431,930.5±19,059.9 vs 448,168.3±31,559.8), post-abortion care (3,206.5±111.7 vs 448,168.3±31,559.8) and pentavalent 1 immunisation (114,701.0±3,701.1 vs 110,915.8±7,209.4), p&gt;0.05. However, there were significant increases in FP utilisation among young people (25.7% to 27.0%), injectable (short-term) FP method uptake (58.2% to 62.3%), caesarean section rate (14.6% to 15.8%), adolescent maternal deaths (6.2% to 10.9%) and fresh stillbirths (0.9% to 1.0%) with a reduction in implants (long-term) uptake (16.5% to 13.0%) (p&lt;0.05). With uncertainty around the duration of the pandemic, strategies to mitigate against catastrophic indirect maternal health outcomes are urgently needed. (Afr J Reprod Health 2021; 25[6]: 76-87)
