HIV infection in orphanages in South Western Nigeria

Background: As a result of the expanding HIV epidemic, affected children may end up in institutionalized care. Objectives: To determine the prevalence of HIV infection among children into orphanages in South Western Nigeria . Admission policies, knowledge and attitude of caregivers with respect to HIVwere also assessed Design: This was a cross sectional study in which interviewer administered questionnaires were used to collect information on consecutive children, heads of the orphanages and caregivers. Rapid HIV antibody testing was carried out. Results: A total of 190 children were enrolled from 7 homes with males accounting for 89 (46.8%). The main reasons for admission into the orphanages were; orphaned 85 (44.7%), abandoned 79 (41.6%) and mental illness in mother 11(5.8%). Two children were HIV positive, giving a prevalence rate of 1.05%. All the homes (100%) had a policy which excluded admission of HIV positive children but seldom carried out HIV testing at entry. Fear of disease transmission to others was the reason given for not admitting such children. Conclusion: The policy which excluded admission of HIV infected children may have contributed to the low prevalence of the infection in the orphanages. There needs to be a reform on the current policies in order to reduce discr iminat ion against HIV orphans.Keywords: HIV; Prevalence; Children; Orphanages; Admission policies; Caregiver

Morbidity and mortality pattern in hospitalized children with sickle cell disorders at the University College Hospital, Ibadan, Nigeria

Objectives: To determine the causes of hospitalization and outcome of children with sickle cell disorders at the University CollegeHospital, Ibadan.Methods: Case files of patients with sickle cell disease who were admittedbetween March 2009 and February 2012 were analysed. Data extractedinclude demographic variables, diagnoses, types of crises, associated infections, complications and outcome of treatment.Results: There were 174 admissions of 161 children with a male femaleratio of 1.3:1. Their ages ranged from nine months to 18 years witha mean of 7.3(4.0) years. Vasoocclusive crisis was present in 107(61.5%), hyper haemolytic crisis in 29 (16.7%) and acute splenic  sequestration in 12 (6.9 %) of all admissions. Associated infectionswere septicaemia in 56 (32.2 %), malaria in 49 (28.2 %), acute osteomyelitis in 24 (13.8%), pneumonia in 23 (13.2%), urinary tract infection in 12 (6.9%) and septic arthritis in 10 (5.7%). Haematocrit was less than 15 % in 36 (20.7%) and blood transfusion administered in 68(39.1%) of admissions. There were three (1.7%) deaths from  cerebrovascular accident, adverse reaction to blood transfusion and meningitis.Conclusion: Prevention and prompt management of crises and infectionsin sickle cell disease is recommended to reduce morbidity andmortality

Contact tracing for SARS-CoV-2: what can be learned from other conditions?

Contact tracing is central to the public health response to COVID-19, but the approach taken has received criticism for failing to make enough of an impact on disease transmission. We discuss what can be learned from contact tracing in other infections, and how the natural history of COVID-19 should shape the strategies used

Calculating the random guess scores of multiple-response and matching test items

For achievement tests, the guess score is often used as a baseline for the lowest possible grade for score to grade transformations and setting the cut scores. For test item types such as multiple-response, matching and drag-and-drop, determin-ing the guess score requires more elaborate calculations than the more straight-forward calculation of the guess score for True-False and multiple-choice test item formats. For various variants of multiple-response and matching types with respect to dichotomous and polytomous scoring, methods for determining the guess score are presented and illustrated with practical applications. The implica-tions for theory and practice are discussed

Developing a Business Case for the Care Coordination and Transition Management Model: Need, Metrics, and Measures

In this descriptive qualitative study, nurse and healthcare leaders\u27 experiences, perceptions of care coordination and transition management (CCTM®), and insights as to how to foster adoption of the CCTM RN role in nursing education, practice across the continuum, and policy were explored. Twenty-five barriers to recognition and adoption of CCTM RN practice across the continuum were identified and categorized. Implications of these findings, recommendations for adoption of CCTM RN practice across the care continuum, and strategies for reimbursement policies are discussed

Separation between coherent and turbulent fluctuations. What can we learn from the Empirical Mode Decomposition?

The performances of a new data processing technique, namely the Empirical Mode Decomposition, are evaluated on a fully developed turbulent velocity signal perturbed by a numerical forcing which mimics a long-period flapping. First, we introduce a "resemblance" criterion to discriminate between the polluted and the unpolluted modes extracted from the perturbed velocity signal by means of the Empirical Mode Decomposition algorithm. A rejection procedure, playing, somehow, the role of a high-pass filter, is then designed in order to infer the original velocity signal from the perturbed one. The quality of this recovering procedure is extensively evaluated in the case of a "mono-component" perturbation (sine wave) by varying both the amplitude and the frequency of the perturbation. An excellent agreement between the recovered and the reference velocity signals is found, even though some discrepancies are observed when the perturbation frequency overlaps the frequency range corresponding to the energy-containing eddies as emphasized by both the energy spectrum and the structure functions. Finally, our recovering procedure is successfully performed on a time-dependent perturbation (linear chirp) covering a broad range of frequencies.Comment: 23 pages, 13 figures, submitted to Experiments in Fluid

Accelerating Curriculum Design: A Love It, Don\u27t Leave It Approach to Creative Process and Idealized Design

Purpose and Background: The Institute of Medicine’s (IOM) report (2010) on the “Future of Nursing” emphasized the need for nurses to lead health care change. One of the key messages in this report is a call to action for nursing schools to re-envision nursing education that focuses on a population-based perspective and emerging roles for nurses across the care continuum. With an evolving focus on primary and community-based care rather than acute care, and recognition of the importance of coordinating care and managing transitions across providers and settings of care, registered nurses now and in the future will need to be prepared with a breadth of knowledge, skills, and competencies. In response, the Jefferson College of Nursing (JCN) embarked on the ambitious task of designing a new 21st century baccalaureate nursing curriculum over a 13-month period. Nursing curriculum design varies widely and can span the course of two to five years. To reduce the lengthy process and ensure faculty commitment, JCN leadership selected a core team of nine faculty members to navigate the full faculty through the design of the curriculum. Each team member was assigned three teaching credits for curriculum development and design. Although a 13-month turnaround time for curriculum design is unprecedented, what is most unique about JCN’s initiative is that it began with a charge of developing an idealized curriculum from a blank slate. To ensure that the curriculum reflected multiple perspectives, the team recruited six stakeholders including a nurse practice partner, health care consumer, community leader, alumnus, current student, and adjunct clinical faculty.
