Fluid replacement therapy for acute episodes of pain in people with sickle cell disease.

BACKGROUND: Treating vaso-occlusive painful crises in people with sickle cell disease is complex and requires multiple interventions. Extra fluids are routinely given as adjunct treatment, regardless of the individual's state of hydration with the aim of slowing or stopping the sickling process and thereby alleviating pain. This is an update of a previously published Cochrane Review. OBJECTIVES: To determine the optimal route, quantity and type of fluid replacement for people with sickle cell disease with acute painful crises. SEARCH METHODS: We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register which comprises of references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings.We also conducted searches of Embase (November 2007), LILACS, www.ClinicalTrials.gov (05 January 2010), and the WHO ICTRP (30 June 2017).Date of most recent search of the Group's Haemoglobinopathies Trials Register: 16 February 2017. SELECTION CRITERIA: Randomised and quasi-randomised controlled trials that compared the administration of supplemental fluids adjunctive to analgesics by any route in people with any type of sickle cell disease during an acute painful episode, under medical supervision (inpatient, day care or community). DATA COLLECTION AND ANALYSIS: No relevant trials have yet been identified. MAIN RESULTS: Sixteen trials were identified by the searches, all of which were not eligible for inclusion in the review. AUTHORS' CONCLUSIONS: Treating vaso-occlusive crises is complex and requires multiple interventions. Extra fluids, generally oral or intravenous, are routinely administered during acute painful episodes to people with sickle cell disease regardless of the individual's state of hydration. Reports of their use during these acute painful episodes do not state the efficacy of any single route, type or quantity of fluid compared to another. However, there are no randomised controlled trials that have assessed the safety and efficacy of different routes, types or quantities of fluid. This systematic review identifies the need for a multicentre randomised controlled trial assessing the efficacy and possible adverse effects of different routes, types and quantities of fluid administered to people with sickle cell disease during acute painful episodes

Differences in Population Dynamics and Uptake of Reproductive Health Services in the Urban and Rural Cohorts of Cross River Health and Demographic Surveillance System of Southern Nigeria

Background: Health and demographic surveillance systems (HDSSs) generate essential health and demographic data from longitudinal surveillance of populations resident in distinctly demarcated enumeration areas. The Cross River HDSS (CRHDSS) located in southern Nigeria includes distinct urban and rural cohorts. Concurrent surveillance of adjacent urban and rural communities provides an opportunity to identify differences in population characteristics and access or utilization of health services. In this paper, we report the result of comparative analysis of rural and urban cohorts of the CRHDSS from November 2012 to December 2018. Methodology: Data was collected through house-to-house interviews performed in 6-monthly cycles through the years. Information obtained included demographic characteristics, pregnancies, child birth, health-seeking behaviour, migration and deaths. Trained field workers collected data from all households in the demographic surveillance area with mobile Android devices (running the ODKCollect). Collected data were transferred electronically to a remote server running on ODKAggregate and further processed by MirthConnect on OpenHDS web application with a MySQL backend database. Data was exported, cleaned and analyzed with the R Statistical Computing Software. Results: Total population undergoing longitudinal health and demographic surveillance was 37,808 persons in 9,452 households with 18,414 males and 19,394 females. The rural cohort made up 47.4% of the population while the urban cohort was 52.6%. Population structure showed that while the rural cohort has a relative depletion of young adults, the urban cohort has preponderance of this population segment indicating the high rate of rural to urban migration. There is also a striking difference in pattern of utilization of reproductive health services by pregnant women. While 68.6% of childbirth in the rural cohort occurred outside the formal health service (at TBAs and at home), 79.1% of childbirth in the urban area occurred in formal health facilities. Both the crude fertility rate, infant mortality and under-five mortality rates were higher in rural than the urban cohorts.Conclusion: Surveillance data showed relative depletion of young adults from rural population cohort, suggesting high rate of rural to urban migration. Majority of childbirths in rural areas still occur outside formal health facilities, which may partly contribute to higher infant mortality rate in the rural cohort. This calls for more efforts to enhance reproductive health services and employment opportunities in rural areas.

Telemedicine for Children with Sickle cell Anemia in a Resource‐Poor Setting during COVID‐19 Pandemic: An Observational Study

Background: The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic has continued to disrupt medical care among patients with sickle cell anemia (SCA). The city lockdowns and restrictions to minimize virus transmission in countries have created gaps in the optimal management of children with SCA. Aim: The aim of this study was to access the clinical experience in the use of mobile health telemedicine for the care of children with SCA. Methods: At the start of national lockdown, text messages were sent to parents of children with SCA who are attending a tertiary hospital in Nigeria. The message included advice to call consultants in the pediatric hemato-oncology unit whenever their wards were sick or due for a routine clinic visit. Information obtained include date of call or text message, complaints, intervention prescribed, and feedback from the parents. Results: There were 115 calls and 43 texts from the parents from April through July 2020. The proportion of calls increased from 16.5% to 33.9%, while texts increased from 23.3% to 30.2% over the months. Responses were significant (P = 0.047). Respiratory symptoms(40%) were the most common complaints. The most frequent interventions were counseling (59%) and drug prescriptions (31%) with the resolution of most symptoms by day 7 (P < 0.001). Parents (60.8%) preferred phone interactions across the months (P < 0.05). No confirmed case of SARS‐CoV‐2 was recorded. Conclusion: Mobile health telemedicine is a beneficial tool in the maintenance of care and possibly prevention of SARS-CoV-2 infection among children with SCA in a resource-limited region. Efforts should be made by stakeholders to institute and promulgate telemedicine during this pandemic

A systematic review of existing national priorities for child health research in sub-Saharan Africa

BACKGROUND: We systematically reviewed existing national child health research priorities in Sub-Saharan Africa, and the processes used to determine them. METHODS: Collaborators from a purposive sample of 20 WHO-AFRO Region countries, assisted by key informants from a range of governmental, non-governmental, research and funding organisations and universities, identified and located potentially eligible prioritisation documents. Included documents were those published between 1990 and 2002 from national or nationally accredited institutions describing national health research priorities for child health, alone or as part of a broader report in which children were a clearly identifiable group. Laboratory, clinical, public health and policy research were included. Two reviewers independently assessed eligibility for inclusion and extracted data. RESULTS: Eight of 33 potentially eligible reports were included. Five reports focused on limited areas of child health. The remaining three included child-specific categories in reports of general research priorities, with two such child-specific categories limited to reproductive health. In a secondary analysis of Essential National Health Research reports that included children, though not necessarily as an identifiable group, the reporting of priorities varied markedly in format and numbers of priorities listed, despite a standard recommended approach. Comparison and synthesis of reported priorities was not possible. CONCLUSION: Few systematically developed national research priorities for child health exist in sub-Saharan Africa. Children's interests may be distorted in prioritisation processes that combine all age groups. Future development of priorities requires a common reporting framework and specific consideration of childhood priorities

Hypocalcemia and Vaso‐Occlusive Painful Crises in Pediatric Sickle Cell Anaemia

Background: Low serum calcium (hypocalcemia) occurs in sickle cell anaemic (SCA) children. Concomitant presence of prolonged corrected QT (QTc) interval on electrocardiogram can ascertain hypocalcemia, especially during vaso-occlusive painful crises (VOC). Aim: The aim of the study was to determine the relationship between hypocalcemia and VOC. Methods: It was a prospective cohort study of 38 SCA children aged 4–17 years during VOC and when the same children were in steady state. Information regarding bone pain and clinical examination were obtained, following which electrocardiography was done during both clinical states. Blood was drawn for total calcium and serum albumin estimation. Results: The mean (standard deviation [SD]) of total calcium was significantly lower during VOC (1.90 [0.19] mmol/l) than during follow-up steady state (2.24 [0.22] mmol/l), P < 0.001. The mean rank of QTc interval was significantly higher during VOC (19.93) than in follow-up steady state (14.50), P < 0.001. Total calcium negatively correlated with QTc intervals during VOC (rs[36] = −0.36, P = 0.029) and follow-up steady state (rs[36] = −0.49, P = 0.002), while QTc interval was highly predictive of hypocalcemia (area under the curve [AUC] = 0.82, P < 0.001). Similarly, total calcium was highly predictive of VOC (AUC = 0.89, P < 0.001) at cutoff point of 2.13 mmol/l with 89.5% sensitivity and 81.6% specificity. Hypocalcemia was significantly observed during VOC than follow‐up steady state (89.5% vs. 21.1%, P < 0.001) with odds ratio of 21.28 (95% confidence interval: 0.012–0.189; P < 0.001). Conclusion: Total calcium <2.13 mmol/l is associated with VOC. Regular total calcium tests should be done. SCA children may benefit from routine oral calcium to reduce frequency of VOC

Artemether-lumefantrine versus artesunate plus amodiaquine for treating uncomplicated childhood malaria in Nigeria: randomized controlled trial

BACKGROUND: The therapeutic efficacy of artesunate plus amodiaquine and artemether/lumefantrine were assessed in an area of Nigeria with high levels of Plasmodium falciparum resistance to chloroquine and sulphadoxine-pyrimethamine. PARTICIPANTS: Children aged 6 to 59 months with uncomplicated P. falciparum infection and parasite density 1,000 to 200,000 parasites/μL enrolled following informed consent by parents. METHODS: Eligible children were randomly assigned to receive either a 3-day course of artesunate (4 mg/kg) plus amodiaquine (10 mg/kg) or 6-dose course of artemether/lumefantrine (20/120 mg tablets) over three days. Patients were followed up with clinical and laboratory assessments until day 14 using standard WHO in-vivo antimalarial drug test protocol. RESULTS: A total 119 eligible children were enrolled but 111 completed the study. Adequate clinical and parasitological response (ACPR) was 47 (87.0%) and 47 (82.5%) for artemether-lumefantrine (AL) and artesunate+amodiaquine (AAMQ) respectively (OR 0.7, 95% confidence interval 0.22 to 2.22). Early treatment failure (ETF) occurred in one participant (1.8%) treated with AAQ but in none of those with AL. Two (3.7%) patients in the AL group and none in the AAQ group had late clinical failure. Late parasitological failure was observed in 9 (15.8) and 5 (9.3%) of patients treated with AAQ and AL respectively. None of participants had a serious adverse event. CONCLUSION: Artemether-lumenfantrine and artesunate plus amodiaquine have high and comparable cure rates and tolerability among under-five children in Calabar, Nigeria

Relationship between care-givers' misconceptions and non-use of ITNs by under-five Nigerian children

<p>Abstract</p> <p>Background</p> <p>Malaria has been a major public health problem in Nigeria and many other sub-Saharan African countries. Insecticide-treated nets have shown to be cost-effective in the prevention of malaria, but the number of people that actually use these nets has remained generally low. Studies that explore the determinants of use of ITN are desirable.</p> <p>Methods</p> <p>Structured questionnaires based on thematic areas were administered by trained interviewers to 7,223 care-givers of under-five children selected from all the six geo-political zones of Nigeria. Bivariate analysis and multinomial logit model were used to identify possible determinants of use of ITN.</p> <p>Results</p> <p>Bivariate analysis showed that under-five children whose care-givers had some misconceptions about causes and prevention of malaria were significantly less likely to use ITN even though the household may own a net (p < 0.0001). Education and correct knowledge about modes of prevention of malaria, knowing that malaria is dangerous and malaria can kill were also significantly associated with use of ITN (p < 0.0001). Knowledge of symptoms of malaria did not influence use of ITN. Association of non-use of ITN with misconceptions about prevention of malaria persisted with logistic regression (Odds ratio 0.847; 95% CI 0.747 to 0.960).</p> <p>Conclusions</p> <p>Misconceptions about causes and prevention of malaria by caregivers adversely influence the use ITN by under-five children. Appropriate communication strategies should correct these misconceptions.</p

Childbirth Practices in the Akpabuyo Rural Health and Demographic Surveillance System

Maternal and neonatal mortality remain high in Nigeria. The State and Federal governments have adopted several strategies to prevent maternal and infant deaths such as the Cross River State Free Health Services to pregnant women and infants, and the National Midwives’ Service Scheme. This study assessed pregnancy and childbirth practices of Nigerian women in rural communities located in Akpabuyo in the Niger Delta region of Nigeria. Women who were pregnant or had recently given birth in a population of 5,668 people under surveillance in some rural communities of Akpabuyo were interviewed to obtain information on pregnancy and childbirth practices. Validated semi-structured questionnaires were administered by well-trained field workers. Completed questionnaires were entered into electronic data forms in OpenHDS software and exported to STATA for analysis. Results showed that, 39.5% of women reported that they had sought prenatal care from a traditional birth attendant (TBA). 84.6% of all births occurred outside the formal health system with the majority attended by TBAs. Only 15.4% of births occurred in hospitals or health centres. The implements used to cut the umbilical cord were knives (46.2%), new razor blades, old razor blades, sharp stone and scissors. The materials used for treating the umbilical cord were mostly methylated spirit (63.1%); other treatment materials were“western medicine”, “black powder” and others including herbs and earth. The study concluded that, childbirth practices that pose significant risk to maternal and newborn health remain common in these rural communities. Majority of births were attended by TBAs despite free delivery services available at the formal health facilities. TBAs should be assisted to enhance their role in health care delivery. Effort should be made to increase public awareness and interest in facility-based services. Keywords: Maternal health, neonatal infection, longitudinal data, pregnancy

Optimum hardware, software and personnel requirements for a paperless health and demographic surveillance system: a case study of Cross River HDSS, Nigeria

Health and Demographic Surveillance Systems (HDSS) are a robust and rigorous data collection, validation, storage, analysis and reporting platforms for community-based data on vital events. These processes make high demands on paper and man-hours with attendant implications on running costs and environmental impact. However, with the rapid development of ICT and increasing affordability of computing devices, some of the manual processes can be replaced with ICT tools. This paper presents a case study of the Cross River HDSS in Akpabuyo Southern Nigeria with a view to highlighting the essential personnel, hardware and software requirements for running an IT-based paperless HDSS in low income settings. The DSA comprised of 22 contiguous EAs of 1370 households. The case study entailed four update rounds, each of which involved field workers visiting households and obtaining information on vital events. The first update round was purely paper-based involving the use of large collections of paper forms for interviews. The last three rounds were IT-based, devoid of paper questionnaires and ran on web-based open source software. Hardware was a set of high-end servers, desktops, tablet PCs and android phones for data collection.   The case study demonstrated the feasibility of running a paperless IT-based HDSS in a resource-poor setting using free and open source software, such as the web-based OpenHDS, MySQL, ODK, MirthConnect, etc. This overcomes the limitations of the popular HRS2 in terms of costs, complexities, and lack of compatibility with changing hardware and system software configurations. However, running IT-based paperless HDSS threw up some challenges, such as cases of poor internet connectivity, absence of GSM network connectivity using mobile devices, and having the right mix of staff with sufficient IT skills. This paper recommended solution strategies for overcoming these challenges. The need for the development of new set of protocols for data quality in a paperless HDSS is also discussed.   Keywords: Health, demographic surveillance system, information technology, paper, environment, enumeration area
