Published: April 2024

Abstract
Background
Ghana is among the top 10 highest malaria burden countries, with about 20,000 children dying annually, 25% of which were under five years. This study aimed to produce interactive web-based disease spatial maps and identify the high-burden malaria districts in Ghana.

Methods
The study used 2016–2021 data extracted from the routine health service nationally representative and comprehensive District Health Information Management System II (DHIMS2) implemented by the Ghana Health Service. Bayesian geospatial modelling and interactive web-based spatial disease mapping methods were employed to quantify spatial variations and clustering in malaria risk across 260 districts. For each district, the study simultaneously mapped the observed malaria counts, district name, standardized incidence rate, and predicted relative risk and their associated standard errors using interactive web-based visualization methods.

Results
A total of 32,659,240 malaria cases were reported among children < 5 years from 2016 to 2021. For every 10% increase in the number of children, malaria risk increased by 0.039 (log-mean 0.95, 95% credible interval = − 13.82–15.73) and for every 10% increase in the number of males, malaria risk decreased by 0.075, albeit not statistically significant (log-mean − 1.82, 95% credible interval = − 16.59–12.95). The study found substantial spatial and temporal differences in malaria risk across the 260 districts. The predicted national relative risk was 1.25 (95% credible interval = 1.23, 1.27). The malaria risk is relatively the same over the entire year. However, a slightly higher relative risk was recorded in 2019 while in 2021, residing in Keta, Abuakwa South, Jomoro, Ahafo Ano South East, Tain, Nanumba North, and Tatale Sanguli districts was associated with the highest malaria risk ranging from a relative risk of 3.00 to 4.83. The district-level spatial patterns of malaria risks changed over time.

Conclusion
This study identified high malaria risk districts in Ghana where urgent and targeted control efforts are required. Noticeable changes were also observed in malaria risk for certain districts over some periods in the study. The findings provide an effective, actionable tool to arm policymakers and programme managers in their efforts to reduce malaria risk and its associated morbidity and mortality in line with the Sustainable Development Goals (SDG) 3.2 for limited public health resource settings, where universal intervention across all districts is practically impossible.

Published: April 2024

AbstractTwo polysaccharides were obtained from dandelion roots (DPR) and dandelion leaves (DPL) via water extraction and ethanol precipitation. Both DPR and DPL were an acid heteropolysaccharide, with a molecular weight of 5.89 × 104 and 28.2 × 104 Da, respectively. Monosaccharide composition results showed that both DPR and DPL contained Man, Glc, Rha, GalA, Glc, Gal, and Ara with a molar ratios of 2.98:1.00:3.67:6.41:2.98:16.70:2.48 and 1.23:1.00:1.06:5.74:2.88:8.59:1.84, respectively. Methylation and NMR analysis showed DPR and DPL, with triple-helix conformations, were mainly composed of 4-ɑ-Galp and 4-ɑ-GalAp, terminated with t-ɑ-Araf, t-ɑ-Rhap, t-ɑ-Glcp and t-ɑ-Manp. DPL showed an immunoprotective effect in cyclophosphamide (Cy)-induced black-bone silky chickens by improving chicken growth performance, increasing the spleen, thymus, and bursa of Fabricius indices, and promoting blood lymphocyte proliferation, the secretion of cytokines (IL-2, IL-6, and INF-γ) and serum immunoglobulin (IgA, IgG, and IgM) levels in a dose-dependent manner. Moreover, the oxidative stress damage in immunosuppressed chickens was significantly reformed after DPL treatment. These findings provide useful information on the potential for application of dandelion polysaccharides as natural nutrients to enhance chicken immune and antioxidant functions.

Contraceptive use and method mix dynamics in Sub-saharan Africa: time trends and the influence of the HIV pandemic
Authors: Bawah Ayaga A. , Kyei Pearl S. , Agyei-Asabere Charles 
Published: April 2024

Abstract
Background
Contraceptive use dynamics continue to be of priority in sub-Saharan Africa because of persistently high levels of fertility. This paper focuses on the use of barrier versus non-barrier contraceptive use in sub-Saharan Africa hypothesizing that the HIV pandemic in the region would be responsible for increases in the use of barrier methods over time.

Methods
This paper uses Demographic and Heath Survey (DHS) data from 32 countries to conduct extensive analysis of trends in contraceptive use and method mix that refers to the distribution of contraceptive methods use among the sexually active population. The paper examines how contraceptive method mix dynamics have changed over time and whether the trends differ by marital status and gender using cross-tabulations. It furthers examines the determinants of method choice using logistic regressions.

Results
The findings indicate that the use of barrier methods, most markedly for unmarried women and men, rose substantially between the late 1980s and late 2000s in the region in tandem with trends in HIV prevalence. The results further show marked differences in method mix by gender with men being more likely to report barrier method use than women.

Conclusions
The findings indicate shifting preferences in contraceptive choice. The time trend analyses highlight the importance of expanding the focus of contraceptive use studies beyond women in this context as the study finds differing trends for men.

Abstract
Background
The purpose of this study was to evaluate the effect of nanoparticles (NPs) of a plant extract on implant osseointegration in vivo. NPs of the Cissus quadrangularis (CQ) extract were synthesized. Twenty Wistar rats were included in the study. The test group (n = 5) had NPs-incorporated, the control group (n = 5) had no incorporation of NPs, and the sham group (n = 5) did not have implants placed. The toxicity profile of NPs was carried out by biochemical analysis before and after the implant placement. The rate of integration was assessed using Cone Beam Computed Tomography (CBCT), Digital X-ray, histology, and scanning electron microscopy (SEM) at intervals of 2, 4, and 6 weeks. Statistical significance between the groups was determined by Analysis of Variance (ANOVA) (p < 0.05) and the differences were uncovered with post hoc Tukey’s test.

Results
Radiographs showed that the bone density around implants with NPs was considerably higher than those without NPs. The osteoid seam along the implant surface was found to be considerably higher in the test group. A noteworthy increase was observed in the bone formation around the implants in bone samples belonging to the test group. Comparing the values at different time intervals, the highest serum Alkaline phosphatase (ALP) activity was noted in the test group after six weeks and the lowest serum Acid phosphatase (ACP) activity was documented in the test group after 6 weeks.

Conclusion
The test group samples exhibited an osseointegration rate of less than 2 weeks thus demonstrating CQ NPs to be a potent osteoinductive agent.

Data-Driven Mergers
Authors: de Cornière Alexandre , Taylor Greg 
Published: April 2024

We study mergers between firms operating in data-connected markets: the data generated as a byproduct of the activity in market A can be used by firms operating in market B. The effects of such a merger depend on whether data trade among independent firms is possible and whether data use benefits consumers or leads to more surplus extraction. When data increases product B’s quality, the merger benefits consumers in both markets if data cannot be traded absent the merger and harms them otherwise. When data are used to extract consumer surplus in market B, the merger increases consumer surplus in market A and reduces it in market B. This paper was accepted by Joshua Gans, business strategy.

Introduction
Equations can calculate pulse wave velocity (ePWV) from blood pressure values (BP) and age. The ePWV predicts cardiovascular events beyond carotid-femoral PWV. We aimed to evaluate the correlation between four different equations to calculate ePWV.

Methods
The ePWV was estimated utilizing mean BP (MBP) from office BP (MBPOBP) or 24-hour ambulatory BP (MBP24-hBP). We separated the whole sample into two groups: individuals with risk factors and healthy individuals. The e-PWV was calculated as follows:

e1−PWV=9.58748315543126−0.402467539733184*age+4.56020798207263*10−3*age2−2.6207705511664*10−5*age2*MBP+3.1762450559276*10−3*age*MBP−1.83215068503821*10−2*MBP

e2−PWV=4.62−0.13*age+0.0018*age2+0.0006*age*MBP+0.0284*MBP

We calculated the concordance correlation coefficient (Pc) between e1-PWVOBP vs e2-PWVOBP, e1-PWV24-hBP vs e2-PWV24-hBP, and mean values of e1-PWVOBP, e2-PWVOBP, e1-PWV24-hBP and e2-PWV24-hBP. The multilevel regression model determined how much the ePWVs are influenced by age and MBP values.

Results
We analyzed data from 1541 individuals; 1374 ones with risk factors and 167 healthy ones. The values are presented for the entire sample, for risk-factor patients and for healthy individuals respectively. The correlation between e1-PWVOBP with e2-PWVOBP and e1-PWV24-hBP with e2-PWV24-hBP was almost perfect. The Pc for e1-PWVOBP vs e2-PWVOBP was 0.996 (0.995–0.996), 0.996 (0.995–0.996), and 0.994 (0.992–0.995); furthermore, it was 0.994 (0.993–0.995), 0.994 (0.994–0.995), 0.987 (0.983–0.990) to the e1-PWV24-hBP vs e2-PWV24-hBP. There were no significant differences between mean values (m/s) for e1-PWVOBP vs e2-PWVOBP 8.98±1.9 vs 8.97±1.8; p = 0.88, 9.14±1.8 vs 9.13±1.8; p = 0.88, and 7.57±1.3 vs 7.65±1.3; p = 0.5; mean values are also similar for e1-PWV24-hBP vs e2-PWV24-hBP, 8.36±1.7 vs 8.46±1.6; p = 0.09, 8.50±1.7 vs 8.58±1.7; p = 0.21 and 7.26±1.3 vs 7.39±1.2; p = 0.34. The multiple linear regression showed that age, MBP, and age2 predicted more than 99.5% of all four e-PWV.

Conclusion
Our data presents a nearly perfect correlation between the values of two equations to calculate the estimated PWV, whether utilizing office or ambulatory blood pressure.

Published: April 2024

Abstract
The quality control of road implementation on the rim and the strengthening of river edges to prevent road collapses need to be studied and developed continuously. In order to carry out maintenance in a cost-effective manner as much as possible, this research aims to provide a way to reach a better understanding of the quality control of riverbank roads. The study conducted an SWOT questionnaire, which is a means of discovering and evaluating the strengths, weaknesses, opportunities, and threats in the field of quality control of river bank roads, and it can help in identifying the optimal path to achieve specific goals and improve the quality of roads in these areas and determine the necessary steps to improve performance and quality in general. It also contributes to enhancing joint cooperation between the concerned parties. The type of questionnaire was closed and included two parts: the first part is the personal information of the respondents, and the second part is related to the subject of the study, which in turn includes four basic axes. It relates to the elements of the SWOT tool and includes questions ranging from 1 to 44. Sixty people from different academic levels in Iraq responded to the questionnaire, and the answers were according to a five-point Likert scale. The Statistical Package for Social Sciences version 26 was used for statistical analysis, and the statistical methods used in this study are Cronbach’s alpha test to measure reliability, validity of the test to measure the validity of the research tool, frequencies, and percentages, or what is known as relative frequencies, arithmetic mean, and standard deviation, relative importance index.
Coupling energy management of power systems with energy hubs through TSO-DSO coordination: a review
Authors: Bagherzadeh Leila , Kamwa Innocent , Delavari Atieh 
Published: April 2024

Abstract
The transition towards a sustainable energy system requires the integration of high-penetration renewable energy sources (RESs) and the use of new energy management frameworks to handle RES variability and uncertainty. The evolution of novel energy management technologies has made it possible to design and operate integrated energy systems (IESs) that couple various energy carriers such as electricity, heat, and gas. The emergence of energy hubs (EHs) offers the potential for greater efficiency, reliability, and flexibility in energy supply and demand. However, integrating EHs into the power system operation remains a significant challenge due to the complex interaction between the transmission system operator (TSO), distribution system operator (DSO), and EHs. Enhanced coordination between TSOs and DSOs is of the utmost importance within this context. This paper first aims to review and highlight the most practical features of EHs including the EH concept, topology, elements, classifications, flexibility resources, and optimization approaches. Subsequently, it describes TSO-DSO roles and all concepts that are in line with the aims of this subject, such as conceptual framework, TSO-DSO coordination schemes, formulation, and solution techniques. Meanwhile, it will identify any remaining research gaps and prospective trends in this respect.
Value creation in a learning community: an interprofessional partnership between nursing home care, education and students
Authors: Heemskerk Wendy M. , van der Linden Anna M. T. , Bussemaker Jet , Wallner Christian 
Published: April 2024

Abstract

Objectives
To assess the value created in a learning community – comprised of different professionals and nursing students – at a nursing home.

Methods
A case study approach was used. Data were collected between 2019 and 2021 through self-reports, observations and stories (interviews, diaries).

Results
The template analysis revealed nine transcending themes, six associated with preexisting value-creation cycles (expected, immediate, potential, applied, realized and transformative value) and three other relevant themes: contextual, factors and value-creation initiators.

Conclusions
A nursing home learning community comprised of diverse professionals in partnership with nursing students shows a variety of value creation and seems to potentially leverage interprofessional and lifelong learning activities, on top of formal nursing education. It is recommended to integrate the value-creation cycles into the processes of learning communities to promote collective decision-making. Research on both the final level of students involved and having residents participate in the learning community would be worthwhile.
Paradox pain sensitivity using cuff pressure or algometer testing in patients with hemophilia
Authors: Ransmann Pia , Tomschi Fabian , Schmidt Alexander , Brühl Marius , Hilberg Thomas 
Published: April 2024

Abstract

Introduction
Pain is a common comorbidity in patients with hemophilia (PwH) due to hemophilic arthropathy. This study aims to explore pain sensitivity in PwH methodologically investigating in cuff pressure testing compared to algometer testing.

Methods
37 PwH and 35 healthy control subjects (Con) enrolled in this study. Joint health status was assessed. Subjective pain was evaluated using numeric rating scales. Pain sensitivity was measured with pressure algometry and cuff pressure algometry. Pressure pain thresholds of the algometer (PPTa) were measured at knee, ankle joints, and forehead. Subsequently, thresholds of cuff pressure were measured at the left and right lower legs (PPTcuff). In both, lower values represent higher pain sensitivity.

Results
PwH exerted a worse joint health status than Con. Pain sensitivity was higher in PwH compared to Con as PPTa of the knee and ankle joints were lower in PwH. No difference was observed in PPTa at the forehead. Contrastingly, lower pain sensitivity was detected in PwH by higher PPTcuff values compared to Con in both legs.

Conclusion
While PPTa of the knee and ankle joints are lower in PwH, PPTcuff are higher in PwH compared to Con. This reveals a paradox situation, highlighting that PwH experience local, joint- and hemophilic arthropathy-related pain, whereas pain sensitivity of non-affected soft tissue structures is lower. The reasons explaining the PPTcuff results remain elusive but might be explained by coping strategies counteracting chronic joint pain, resulting in lower sensitivity at non-affected structures.
Opacité et Intermédialité chez le cinéma de Marguerite Duras
Authors: Guimarães de Oliveira Luciene 
Published: April 2024

Le cinéma de Marguerite Duras, notamment ses films des années 1970, s’oppose au cinéma grand public à travers plusieurs procédés, tel que celui de briser l’illusion réaliste et référentielle, ou le principe de transparence. Par exemple, l’apparition du matériel de tournage dans la mise en scène, ou la caméra, met en évidence l’opacité de son cinéma. Nous proposons donc d’interroger le cinéma durassien selon ses procédés dysnarratifs, ainsi que son rapport de nature intermédiale avec la littérature.

Opacidade e intermedialidade no cinema de Marguerite Duras
Resumo: O cinema de Marguerite Duras, especialmente seus filmes dos anos 1970, opõe-se ao cinema convencional por meio de vários processos, como a quebra da ilusão realista e referencial, ou o princípio da transparência. Por exemplo, a aparição de equipes de filmagem na mise-en-scène, ou a câmera, destaca a opacidade de seu cinema. Para tanto, propomos questionar o cinema durassiano segundo seus processos disnarrativos, bem como sua relação intermediária com a literatura.

Convergencia de las prácticas discursivas y las prácticas pedagógicas en la formación docente
Authors: Londoño Vásquez David Alberto , Rivas Campo Yulieth 
Published: April 2024

El artículo revisa los puntos de encuentro entre las prácticas discursivas y las prácticas pedagógicas en la formación docente, la cual se deriva de un proyecto interinstitucional sobre Prácticas Discursivas sobre la Alta Dirección y los Servicios Educativos y su incidencia en las Políticas Educativas e Institucionales en Colombia y América Latina. El objetivo general de la investigación fue develar los constructos predominantes en relación con las prácticas discursivas y las categorías subyacentes en los artículos de revistas latinoamericanas indexadas en Scielo, Scopus y Web of Science, entre 2018 y 2022, en relación con el campo de la educación. Para ello, se propuso una revisión sistemática hermenéutico-comprensiva. Para la cual, se construyó una fórmula que permitió identificar los elementos selectivos necesarios para conformar el corpus; dicha fórmula fue aplicada en las bases de datos seleccionadas y se llevó a cabo una delimitación más precisa con colaboración de tres expertos a través de la herramienta Rayyan. Para la sistematización, se diseñó una matriz de múltiple-entrada. La codificación selectiva permitió obtener dos categorías: Las prácticas discursivas en constante tensión por el lenguaje, el discurso y el poder, y la formación docente como una construcción histórica, contextual y discursiva, permitiendo identificar la influencia de las perspectivas epistemológicas en su consolidación conceptual.
