Authors: Sam Napoleon Bellua , Aboyine Thomas , Tackie-Otoo Theresah
Published: January 2025

Introductions: Maternal and newborn mortality remains a critical global public health challenge, especially in middle- and lower-income countries. One of the most effective strategies for reducing these mortality rates is the adequate utilization of antenatal care (ANC). This study investigated the determinants influencing ANC utilization and aimed to predict the demographic characteristics that impact ANC attendance using Structural Equation Modelling (SEM). Methods: A cross-sectional analytical study was conducted with 254 pregnant women at St. Lucas Hospital in Ghana. Data were collected using a structured questionnaire. SEM and Chi-square analysis were employed to model and examine the determinants influencing antenatal care utilization. Results: The findings revealed that the majority (72%) of postpartum mothers had four or more ANC contacts during their most recent pregnancy, with 47.6% initiating ANC attendance in the first trimester. ANC usage was significantly associated with maternal education level (P = 0.000), occupational status (P = 0.000), age (P = 0.030), marital status (P = 0.034), religious affiliation (P = 0.000), husband's education (P = 0.000), and husband's occupation (P = 0.000).. Furthermore, SEM analysis showed that community factors (P = 0.005) and health provider factors (P = 0.000) were important in ANC utilization. This study identified significant demographic factors, such as maternal and husband’s education and occupation, and highlighted the critical roles of health providers and community factors in ANC utilization. Conclusions: This study established some essential determinants such as health provider and community factors in the utilization of ANC contacts. The study also revealed some demographic characteristics as crucial determinants of ANC attendance.

Introduction : La péritonite aigue généralisée est une urgence médico chirurgicale fréquente chez l’enfant  dont les étiologies sont diverses. Nous rapportons deux cas rares de péritonite biliaire primitive chez l’enfant dont les suites opératoires ont été simples. Observation clinique : il s’agissait de deux garçons âgés de 07 et 11ans admis aux urgences pour une douleur abdominale évoluant depuis trois semaines au moins chez qui le diagnostic initial de péritonite aigue généralisée par perforation iléale d’origine typhique probable a été posé. Ils ont tous deux bénéficié d’une laparotomie qui a permis de découvrir une perforation vésiculaire dans le premier cas et une association de perforation vésiculaire et iléale dans l’autre cas. Il a été réalisé une cholécystectomie chez les deux, une résection anastomose iléale chez le second, un lavage et drainage péritonéal. Conclusion : la perforation vésiculaire est une lésion rare chez l’enfant et on doit y penser devant une péritonite aigue chez l’enfant.
Introduction: Acute generalized peritonitis is a common medical-surgical emergency with various etiologies. We report two rare cases of primary biliary peritonitis in children at CHUD/B-A whose surgical outcomes were favorable. Clinical observation: These were two male children aged 07 and 11 years admitted to the emergency department for abdominal pain that had been evolving for at least three weeks for whom the initial diagnosis of acute generalized peritonitis by ileal perforation of probable typic origin was made. They both underwent a laparotomy which revealed vesicular perforation in the first case and a combination of vesicular and ileal perforation in the other. A cholecystectomy was performed in both, an ileal anastomosis resection in the second, and peritoneal lavage and drainage. Conclusion: vesicular perforation is a rare lesion in children and should be considered in the case of peritonitis.

The COVID-19 pandemic triggered an unprecedented backslide in global immunization programs, increasing the number of zero-dose children-those who have not received any vaccinations—from 13.3 million in 2019 to 18.1 million in 2021. This surge poses a significant threat to public health, especially in low- and middle-income countries (LMICs), where healthcare systems are already fragile. This scoping review focused on the impact of the pandemic on childhood immunization, with a focus on zero-dose children, and to identify effective interventions for rebuilding resilient immunization systems. Data from WHO, UNICEF, and Gavi were comprehensively reviewed. The IRMMA (Identify, Reach, Monitor, Measure, Advocate) framework was used to structure the analysis of evidence-based interventions across diverse settings. Consolidated findings show that in 2022, 20.5 million children missed one or more vaccines, with 14.3 million classified as zero-dose children. Despite improvements from 2021, these numbers remain higher than pre-pandemic levels. Countries such as Nigeria (2.3 million zero-dose children), India (1.1 million), and Ethiopia (1.1 million) are most affected.
Our review highlights the importance of strengthening health systems and leveraging innovative strategies such as drone delivery and digital health platforms for reaching zero-dose children. To ensure sustainability, policy interventions must focus on integrating immunization efforts into national healthcare frameworks. This includes prioritizing workforce development, enhancing supply chain management, and fostering partnerships with community leaders to rebuild trust and address vaccine hesitancy. Specific interventions, such as deploying mobile vaccination units, implementing culturally tailored health messaging, and utilizing real-time monitoring technologies, are recommended to target under-reached populations. The pandemic has exacerbated existing vulnerabilities in immunization systems but coordinated global efforts, like the "Big Catch-Up" campaign, offer a pathway to recovery and long-term sustainability. This scoping review underscores the urgent need for robust, context-specific policies and targeted interventions to bridge the immunization gap and protect vulnerable populations from vaccine-preventable diseases.

Molluscs play an important role in public and veterinary health, making the continuous study of their distribution essential. The main goal of this investigation was to examine the distribution of freshwater molluscs in Lake Kivu, located on the DR Congo side. Semi-quantitative surveys conducted from January to December 2019 focused on selected sites within the lake, covering both the dry and wet seasons. Snails in the littoral zone of Lake Kivu were collected using a plankton net and pliers. The physicochemical parameters of the water at each site were measured using standard water quality analysis methods. The collected snails were morphologically identified using various identification keys. Biomphalaria species were analyzed (cercariometry) for trematode infestation. A total of 1,331 snails belonging to seven genera and 18 species were recorded during the study. The relative abundance of the recorded snail species was as follows: Biomphalaria pfeifferi (49.6%), Biomphalaria smithi (16.6%), Gabbiella spirilosa (10.6%), Bulinus truncatus (10.1%), Lymnaea natalensis (6.5%), Helisoma duryi (1.5%), Pila ovata and Tomichia ventricosa (0.8% each), Melanoides tuberculata (1.7%), Lymnaea columella and Tomichia hendrexyx (0.9% each), Bulinus forskalii and Tomichia zwellandanensis (0.9% each), Physa acuta (0.4%), Corbicula fluminalis (1.1%), Lymnaea palustris (0.2%), Tomichia kivuensis and Segmentorbis kempi (0.1% each). This study clarified the distribution and seasonal abundance of freshwater snails in Lake Kivu, DR Congo. Eighteen species of freshwater snails were identified during the malacological survey. The observed snail distribution provides insights into the epidemiology of trematode infections in the study area and highlights potential risks to human and animal health. The implications of these findings for controlling snail-borne trematodes are also discussed.

This study was aimed to determine the abnormal Red blood cell parameters among malnourished children underـfive years attending AL-Sadaqa teaching hospital‚ Aden governorate and to determine the associated factors related to malnutrition as well as abnormal parameters among those children. A hospital based cross-sectional study was conducted on 101 malnourished children under 5years. The blood samples were collected from all studied group and the hematological parameters were measured by using automated hematological analyzer from (Sysmex) Company and the data was analyzed by SPSS. Out of 101 malnourished children, majority were females 55(54.5%).The highest percentage was 51.5% among MAM while the SAM and 48.5%. The means of RBCs, HCT, MCV and MCHC were slightly decreased with increasing of RDW among SAM children than MAM. Significant associations were found between children with age group >20 and their residence and acute malnutrition (p=0.049 and p=0.015). About 81.40% of malnourished children had anemia with only 4% of children had severe anemia. The percentages of low RBCs, HCT, MCV, MCH and MCHC were 48%, 92.2%, 88.2%, 93.1% and 63.7%, respectively, while 77.2% of children had high RDW. Significant associations between residence, illustrate and primary school education of both fathers and Mothers and anemia (p=0.043, 0.005, 0.003, 0.02 and 0.005), respectively. It can be concluded that the prevalence of SAM and anemia among children under-five years in Aden, Yemen were high.

Published: January 2025

Assessing landslide susceptibility in a municipality is crucial for disaster prevention, and Artificial Neural Networks (ANN´s) have proven effective in this analysis. This study aimed to model landslides susceptibility in the municipality of Joinville, Santa Catarina state, southern Brazil, using ANNs. The municipality has a significant history of such events, allowing for an inventory of occurrence areas (OC) through polygon mapping on satellite images. For non-occurrence areas (NO), a 1 km radius buffer was used, subtracting OC from it. Random points were generated at 10 m intervals, with a value of 1 for OC and 0 for NO. The explanatory variables were divided into three groups: (i) morphometric variables, (ii) horizontal distances to roads and structural lineaments, and (iii) geo-environmental cartographic databases. Five ANN´s configurations were tested. Validation employed metrics such as area under the ROC curve (AUC) and overall accuracy (ACC), with the best modeling yielding an AUC of 0.90 and ACC of 0.84. This result utilized all explanatory variables except land use and cover, which caused a slight bias in the ANN due to the predominance of landslides in forested areas in the inventory. Geology played a crucial role in determining susceptibility.

Los resultados mostraron que los bloques con cabeceo en las caras laterales presentaron una disminución del 12.5% en la capacidad de carga y del 11.33% en la rigidez, en comparación con los cabeceados sobre el área bruta. Este estudio se enfoca en bloques huecos de concreto y concluye que el uso de un denominador variable conduce a una interpretación errónea de su resistencia.
Technology Focus: EOR Modeling (January 2025)
Authors: Hendraningrat Luky
Published: January 2025

Most major global oil and gas companies have committed themselves to decarbonization strategies that reduce the carbon footprint and work toward the goals of climate-change mitigation. These commitments include the use of renewable energy sources, improvements in energy efficiency, and development of technologies that can capture and store carbon emissions. Even with such commitments, energy demand continues to rise globally, driven by population growth, industrialization, and economic progress. These are significant because they have a high energy density and an existing infrastructure.

Enhanced oil recovery (EOR) techniques, particularly those involving CO2 injection (CO2-EOR), can bridge the gap between current energy needs and future renewable energy adoption. CO2-EOR maximizes oil recovery and provides an attractive and commercially established technique to store CO2 underground.

EOR modeling is crucial because complex simulation is required to predict the behavior of CO2 and its interaction with the oil and reservoir rock. EOR modeling can be enhanced by recent and rapid developments in data-driven approaches, machine learning, and artificial intelligence to improve speed, robustness, and accuracy in predicting CO2-EOR processes.

Such enhancement in predictive accuracy may lead to more-efficient, cost-effective, and sustainable EOR processes, ensuring that the oil industry is capable of meeting growing global energy demand with reduced environmental impact.

Advancing the development of Deep Learning and Machine Learning models for oral drugs through diverse descriptor classes: A focus on Pharmacokinetic Parameters (Vdss and PPB)
Authors: Bantu Rakesh , Phukan Samiron , Haydar Simon
Published: January 2025

In the present study, we report a predictive deep learning (DL) and machine learning (ML) model for pharmacokinetics (PK) parameters such as volume of distribution (Vdss) and plasma protein Binding (PPB). Using DL & ML algorithms our study provides a deeper and novel insights into the role of molecular descriptors in determining the PK parameters such as Vdss and PPB. FDA approved drugs with oral route of administration and having reported PK parameters were taken as the dataset. This was used for establishment of the foundational datasets followed by computation of different molecular descriptor classes.
Feature engineering by Boruta algorithm exhibited significant increase in accuracy of the models. Features identified by Boruta algorithm, were trained for different models separately- for both Vdss and PPB. The highest predictive scores amongst the models were achieved in Gradient Boosting (GB) and Stacking Classifier with 80% and 78% for Vdss. In the case of PPB, Random Forest (RF) and Gradient Boosting (GB) algorithm predicted the highest scores of 73% and 71% respectively in comparison to all other algorithms.
In summary we report here appropriate ML algorithms like Stacking Classifier - by utilizing an unreported feature engineering algorithm -to predict Vdss and PPB individually considering over 67 descriptors each with ≥80% accuracy and 73% accuracy respectively.
Additionally, we developed models based on the shared descriptors between Vdss and PPB. Quantum chemical descriptors like MLFERs (MLFER_BH, MLFER_BO & MLFER_E) and Topological descriptors like piPC5, piPC6, piPC9 & TpiPC identified as the common drivers of the functional activity of Vdss and PPB together.

Al Hudaydah recorded the highest number of malaria cases (1,231,294), followed by Hajjah (623,937), Taiz (450,051), Dhamar (167,399), Sa'adah (157,881), and Al-Mahweet (154,763). The overall incidence rate of malaria cases and P. falciparum, respectively, was 8.9 and 2.66 per 1,000 people. The highest mean incidence rate of malaria was recorded in Al Hudaydah, Hajjah, Al-Mahweet, Sa'adah, and Abyan, respectively, at 29.71, 19.49, 14.98, 10.62, and 10.14 per 1,000 people. Yemen reported 704 (0.02%) malaria death cases with an overall rate of case fatality of 0.03% and a mortality rate of 0.18 per 100,000 populations. The trend of case fatality decreased from 0.029% in 2006 to 0.015% in 2020, while the mortality rate per 100,000 individuals decreased from 0.3 in 2006 to 0.08 in 2021.
Conclusion: It currently suggests a continuous increase in the malaria burden without specifying trends or fluctuations and is becoming a public health threat and causing widespread concern. Therefore, the treatment and prevention of malaria infection are crucial for reducing mortality and complications by increasing the use of vector control tools and promoting early diagnosis and treatment.

Published: January 2025

Invasive exotic earthworms have been identified as a major ecological threat to forest ecosystems in the Great Lakes region, affecting soil structure, nutrient cycling, and biodiversity. Understanding biological parameters such as body length, weight, growth rate, and regeneration patterns of these earthworms is crucial first step in comprehending their life cycle and their impacts on ecological processes in terrestrial ecosystems. In this study, an earthworm survey was conducted in the Huron Mountains of Michigan's Upper Peninsula. The earthworms were captured from sampling quadrats, identified to species, and their body mass (dry weight) and body length were measured. The purpose of the study was to develop the length-weight relationship (LWR) for the invasive exotic earthworm species that appeared in this area. Results showed that three invasive earthworm species were found in the studied forests, and they were: Dendrobaena octaedra, Aporrectodea longa, and Lumbricus terrestris. Among them, L. terrestris exhibited the largest size (mean length: 60.4 mm; mean weight: 0.254 g), while D. octaedra was the smallest (mean length: 25.5 mm; mean weight: 0.012 g). The LWR regression equations were: W = 0.00001L2.135 for D. octaedra; W = 0.000001L2.816 for A. longa; and W = 0.000003L2.618 for L. terrestris. These findings highlighted differences in growth patterns that may be influenced by forest composition and micro-environmental factors. This study provided valuable insights into the biological characteristics of invasive exotic earthworms and their potential impacts on North American forest ecosystems.
Does Cross-border E-commerce Promote the Internationalization of SMEs in BRICS Countries?— Evidence From China and Brazil
Authors: Xin Mengni , Mendonça António
Published: January 2025

The study aims to examine how cross-border e-commerce has influenced the internationalization of small and medium-sized enterprises (SMEs) in BRICS countries from 2008 to 2023. It places particular emphasis on China and Brazil, given their significance as representative economies within the group. A Two-Stage Least Squares model is employed to reveal that cross-border e-commerce substantially enhances the internationalization of SMEs, although the effects differ. Due to developed e-commerce infrastructure, a supportive legal environment, widespread adoption of digital payments, and sizeable investments in logistics and technology, the impact is particularly strong in China. Comparatively, Brazil faces challenges, including limited infrastructure and high tariff barriers, which hinder the potential of cross-border e-commerce to promote SMEs’ internationalization effectively. The results indicate that GDP growth supports the internationalization of SMEs in certain BRICS nations, possibly due to varying economic conditions and transitions within these economies. Internet penetration rates show a positive correlation with SMEs’ internationalization in BRICS countries, which highlighting the crucial role of digital infrastructure; while high tariffs are widely acknowledged as a major barrier, limiting SMEs’ ability to leverage cross-border e-commerce effectively. The research suggests that BRICS countries require customized policies to strengthen digital infrastructure and reduce trade barriers, enabling SMEs to reach global markets more effectively. Future studies should involve detailed analyses of each BRICS member, exploring how advancing technologies such as artificial intelligence and blockchain could further support SMEs’ internationalization through cross-border e-commerce.

Mechanistic Comparisons of MICP-treated Residual Soil and Sand Part I – Microstructural Formation and Deformation Behaviour of Soils

Published: January 2025

The application of MICP in improving fine-grained soil or soil containing fines, such as clay or residual soil has increasingly drawn attentions in recent years. However, there are still very limited studies focusing on the comparison between the behaviour of MICP-treated soil containing fines and the more established MICP-treated sand. This study investigates the differences of microstructural formation and deformation behaviour between (untreated and MICP) residual soil and sand through a series of monotonic undrained triaxial tests. The untreated and MICP-treated soils were prepared at a slightly dense state (nearly 80 % of relative density) and subjected to three levels of consolidation pressure (i.e. 40 kPa, 120 kPa, and 220 kPa), before being sheared under undrained condition. A significant improvement in the mechanical behaviour was observed in the bio-treated residual soil despite a low concentration of calcium carbonate content was precipitated (< 5.0 %). This finding was encouraging for field applications of the MICP ground improvement technology in residual soils that were typically known for containing appreciable fines content and being less permeable than sand. From the results, the isotropic compression behaviour and the undrained compressive strength of the MICP-treated residual soil were enhanced significantly. The MICP-treated residual soils tended to manifest a more isotropic deformation behaviour and possessed an elastic soil fabric, as compared to the untreated counterpart which showed anisotropic behaviour. In practical sense, the lightly treated residual soil behaved like a dense soil on account of the densification effect within the pore structure and enhanced interparticle strength. Despite there was almost no alteration of mechanical behaviours in the dense sand, certain implications were gained and will be useful in the comparison with microstructure of residual soil.

Published: January 2025

Background
In low-income countries, clinicians trained through a context-specific trauma surgery fellowship program (TFP) can help reduce injury-related mortality to levels closer to those observed in higher-resource settings. Successful implementation, however, hinges on buy-in from local clinicians. We therefore assessed clinician support for a potential TFP in Uganda, considering perceived need, curricular recommendations, barriers, and motivating factors.
Methods
After cognitive interviews with experts and questionnaire pilot testing, we cross-sectionally surveyed Ugandan consultants (general surgeons and procedural specialists involved in trauma care) and surgical residents at a tertiary, national referral hospital. Respondent percentages were calculated for multiple-choice answers, and we performed thematic analysis of free-text responses using a primarily inductive approach.
Results
Among 46 faculty (from 13 specialties) and 42 resident respondents, 86% supported a Ugandan TFP. Respondents recommended incorporating emergency general surgery (66%), critical care (84%), and international rotations (76%) into the curriculum. Severe resource and structural deficiencies (82%) and concern about governmental support for post-training employment and compensation (66%) were leading perceived barriers to TFP implementation. Most faculty felt a TFP would improve patient outcomes (93%), overall trainee education (77%), and clinical efficiency (68%). Free-text responses were consistent with survey themes, indicating acute awareness of current trauma system inadequacies and conviction that a TFP would reduce injury-related mortality.
Conclusions
Ugandan clinicians who care for injured patients view a TFP as crucial to improving injury-related outcomes, despite known barriers. TFP implementation should incorporate curricular recommendations from this survey and address widespread concerns about financial and infrastructural support from the national government and local institutions.

Published: January 2025

Background
Inhibitors targeting the programmed death ligand 1 (PD-L1) and angiogenesis inhibitors used for targeted treatments against metastatic renal cell carcinoma (mRCC) have garnered considerable attention in current years.
Objective
We aim to report the latest and most extensive meta-analysis for providing an evidence-based comparison of the safety and efficacy outcomes of atezolizumab plus bevacizumab versus sunitinib for mRCC.
Methods
The databases PubMed, Web of Science, and Embase were searched up to March 2023, and studies comparing the clinical outcomes in patients with mRCC who were given atezolizumab plus bevacizumab versus sunitinib were collected. The methodological quality of studies of interest was assessed using the risk of bias assessment tool from Cochrane Collaboration.
Results
This meta-analysis involved six eligible studies published between 2018 and 2022. Combined analysis indicated that atezolizumab plus bevacizumab compared with sunitinib results in enhanced progression-free survival (PFS), overall survival (OS), overall response rate (ORR), complete response (CR), and partial response (PR), as well as a lower incidence of adverse events (AEs). The time to deterioration (TTD) based on the MD Anderson Symptom Inventory (MDASI) showed improvement. However, TTD based on the Brief Fatigue Inventory (BFI) fatigue severity, the outcome of stable disease, and progressive disease showed no significant differences.
Conclusion
This study demonstrated that the combined therapy of atezolizumab plus bevacizumab is more effective and safer than sunitinib for mRCC.
