Published: August 2024

Study’s Novelty/Excerpt

This study compares the utility, sensitivity, specificity, and predictive values of microscopy with that of Rapid Diagnostic Tests (RDTs) in diagnosing malaria among children in Specialist Hospital Sokoto.
The novelty lies in its focus on a specific pediatric population in a resource-limited setting, providing valuable data on the comparative effectiveness of these diagnostic methods in real-world clinical practice.
The findings highlight the higher positivity rate of microscopy, advocating for its continued use alongside RDTs to ensure accurate malaria diagnosis and optimal patient care in similar environments.

Full Abstract
Malaria is a life-threatening disease primarily found in tropical countries, and it is the leading cause of morbidity and mortality among children. Diagnosis of malaria depends largely on clinical presentations and laboratory diagnosis. Microscopy is the gold standard for laboratory malaria diagnosis but requires adequate training and time compared to Rapid Diagnostic Tests (RDTs). The study compared the utility, sensitivity, specificity, and predictive values between microscopy and RDTs in diagnosing malaria among children accessing care in Specialist Hospital Sokoto. A total of 367 blood samples of consented children who met the study inclusion criteria were examined. All samples were screened for malaria using RDT thin and thick blood films. Of the 367 samples assessed, RDT was positive for 202 (55.0%) and negative for 165 (45.0%), while microscopy was positive for 235 (64.1%) and negative for 132 (35.9%), a non-statistically significant (χ2 = 0.090, P = 0.922) difference was observed when both positive tests were compared. The Rapid diagnostic tests (RDTs) showed a sensitivity of 85.95% and a specificity of 83.33%. This study confirms the higher positivity rate of microscopy to RDTs in diagnosing malaria. As such, RDTs are useful for rapid malaria diagnosis, especially in resource-limited settings; microscopy should be encouraged as much as possible for children to avoid missing any positive cases.

This community service aims to increase students' knowledge and transformational leadership skills so that they can apply transformational leadership when carrying out learning practices in the classroom in the future. Nineteen students participated in the activity, but only 18 completed the evaluation. The science and technology transfer team includes the concepts and dimensions of transformational leadership, integration strategies for transformational leadership using scientific learning models, and how to evaluate students' transformational leadership. The three sciences and technologies were transferred using three methods, namely lectures and discussions, exercises, as well as presentations and reflections. The team evaluated service activities (pre test-post test) using seven open questions developed from the dimensions of transformational leadership developed by Carless et al. (2000). The results showed an average increase in understanding of transformational leadership in the medium category (0.3 <0.7). The highest increase was in the second dimension, namely team development, with a value of 0.70. Meanwhile, the dimension with the lowest increase was charismatic, with a value of 0.30. The other five dimensions are in the value range of 0.47-0.65 or are included in the medium category. In the future, service can be expanded by evaluating students' transformational leadership from the perspective of team/group members in learning activities to provide a more operational evaluation perspective on students' transformational leadership experiences.
Applicability of the inverse dispersion method to measure emissions from animal housings

Published: August 2024

Abstract. Emissions from agricultural sources substantially contribute to global warming. The inverse dispersion method (IDM) has been successfully used for emission measurements from various agricultural sources. The IDM has also been validated in multiple studies with artificial gas releases mostly in open fields. Release experiments from buildings have rarely been conducted and were partly affected by additional nearby sources of the target gas. Specific release studies for naturally ventilated animal housings are lacking. In this study, a known and predefined amount of methane (CH4) was released from an artificial source inside a barn that mimicked a naturally ventilated dairy housing, and IDM recovery rates, using a backward Lagrangian stochastic (bLS) model, were determined. For concentration measurements, open-path devices (OPs) with a path length of 110 m were placed in a downwind direction of the barn at fetches of 2.0h, 5.3h, 8.6h, and 12h (h equals the height of the highest obstacle), and a 3D ultrasonic anemometer (UA) was placed in the middle of the first three OP paths. Upwind of the barn, an additional OP and a UA were installed. The median IDM recovery rates determined with the UA placed upwind of the barn and the downwind OP ranged between 0.55–0.75. It is concluded that, for the present study case, the effect of the building and a tree in the main wind axis led to a systematic underestimation of the IDM-derived emission rate probably due to deviations in the wind field and turbulent dispersion from the underlying assumptions of the used dispersion model.
Late Pleistocene glacial terminations accelerated by proglacial lakes

Published: August 2024

Abstract. During the glacial cycles of the past 800 000 years, Eurasia and North America were periodically covered by large ice sheets, causing up to 100 m of sea-level change. While Late Pleistocene glacial cycles typically lasted 80 000–120 000 years, the termination phases were completed in only 10 000 years. During these glacial terminations, the North American and Eurasian ice sheets retreated, which created large proglacial lakes in front of the ice-sheet margin. Proglacial lakes accelerate deglaciation as they facilitate the formation of ice shelves at the southern margins of the North American and Eurasian ice sheets. These ice shelves are characterized by basal melting, low surface elevations, and negligible friction at the base. Here, we use an ice-sheet model to quantify the (combined) effects of proglacial lakes on Late Pleistocene glacial terminations by examining their interplay with glacial isostatic adjustment (GIA) and basal sliding. We find that proglacial lakes accelerate the deglaciation of ice sheets mainly because there is an absence of basal friction underneath ice shelves. If friction underneath grounded ice is applied to floating ice, full deglaciation is postponed by a few millennia, resulting in more ice remaining during interglacial periods and no extensive ice shelves forming. Additionally, the large uncertainty in melt rates underneath lacustrine ice shelves translates to an uncertainty in the timing of the termination of up to a millennium. Proglacial lakes are created by depressions in the landscape that remain after an ice sheet has retreated. The depth, size, and timing of proglacial lakes depend on the rate of bedrock rebound. We find that if bedrock rebounds within a few centuries (rather than a few millennia), the mass loss rate of the ice sheet is substantially reduced. This is because fast bedrock rebound prevents the formation of extensive proglacial lakes. Additionally, a decrease in ice thickness is partly compensated for by faster bedrock rebound, resulting in a higher surface elevation; lower temperatures; and a higher surface mass balance, which delays deglaciation. We find that a very long bedrock relaxation time does not substantially affect terminations, but it may lead to a delayed onset of the next glacial period. This is because inception regions, such as northwestern Canada, remain below sea level throughout the preceding interglacial period.
Modelling Mediterranean ocean biogeochemistry of the Last Glacial Maximum

Published: August 2024

Abstract. We present results of simulations performed with a physical–biogeochemical ocean model of the Mediterranean Sea for the Last Glacial Maximum (LGM) and analyse the differences in physical and biochemical states between the historical period and the LGM. Long-term simulations with an Earth system model based on ice sheet reconstructions provide the necessary atmospheric forcing data, oceanic boundary conditions at the entrance to the Mediterranean Sea, and river discharge to the entire basin. Our regional model accounts for changes in bathymetry due to ice sheet volume changes, reduction in atmospheric CO2 concentration, and an adjusted aeolian dust and iron deposition. The physical ocean state of the Mediterranean during the LGM shows a reduced baroclinic water exchange at the Strait of Gibraltar, a more sluggish zonal overturning circulation, and the relocation of intermediate and deep-water-formation areas – all in line with estimates from palaeo-sediment records or previous modelling efforts. Most striking features of the biogeochemical realm are a reduction in the net primary production, an accumulation of nutrients below the euphotic zone, and an increase in the organic matter deposition at the seafloor. This seeming contradiction of increased organic matter deposition and decreased net primary production challenges our view of possible changes in surface biological processes during the LGM. We attribute the origin of a reduced net primary production to the interplay of increased stability of the upper water column, changed zonal water transport at intermediate depths, and lower water temperatures, which slow down all biological processes during the LGM. Cold water temperatures also affect the remineralisation rates of organic material, which explains the simulated increase in the organic matter deposition, which is in good agreement with sediment proxy records. In addition, we discuss changes in an artificial tracer which captures the surface ocean temperature signal during organic matter production. A shifted seasonality of the biological production in the LGM leads to a difference in the recording of the climate signal by this artificial tracer of up to 1 K. This could be of relevance for the interpretation of proxy records like, e.g., alkenones. Our study not only provides the first consistent insights into the biogeochemistry of the glacial Mediterranean Sea but will also serve as the starting point for transient simulations of the last deglaciation.
Technical note: Optimizing the in situ cosmogenic 36Cl extraction and measurement workflow for geologic applications

Published: August 2024

Abstract. In situ cosmogenic 36Cl analysis by accelerator mass spectrometry (AMS) is routinely employed to date Quaternary surfaces and assess rates of landscape evolution. However, standard laboratory preparation procedures for 36Cl dating require the addition of large amounts of isotopically enriched chlorine spike solution; these solutions are expensive and increasingly difficult to acquire from commercial sources. In addition, the typical workflow for 36Cl dating involves measuring both 35Cl/37Cl and 36Cl/Cl concurrently on the high-energy (post-accelerator) end of the AMS system, but 35Cl/37Cl determinations using this technique can be complicated by isotope fractionation and system memory during measurement. The traditional workflow also does not provide 36Cl extraction laboratories with the data needed to calculate native Cl concentrations in advance of 36Cl/Cl measurements. In light of these concerns, we present an improved workflow for extracting and measuring chlorine in geologic materials. Our initial step is to characterize 35Cl/37Cl on sample aliquots of up to ∼1 g prepared in Ag(Cl, Br) matrices, which greatly reduces the amount of isotopically enriched spike solution required to measure native Cl content in each sample. To avoid potential issues with isotope fractionation through the accelerator, 35Cl/37Cl is measured on the low-energy, pre-accelerator end of the AMS line. Then, for 36Cl/Cl measurements, we extract Cl as AgCl or Ag(Cl, Br) in analytical batches with a consistent total Cl load across all samples; this step is intended to minimize source memory effects during 36Cl/Cl measurements and allows the preparation of AMS standards that are customized to match known Cl contents in the samples. To assess the efficacy of this extraction and measurement workflow, we compare chlorine isotope ratio measurements on seven geologic samples prepared using standard procedures and the updated workflow. Measurements of 35Cl/37Cl and 36Cl/Cl are consistent between the two workflows, and 35Cl/37Cl values measured using our methods have considerably higher precision than those measured following standard protocols. The chemical preparation and measurement workflow presented here (1) reduces the amount of isotopically enriched chlorine spike used per rock sample by up to 95 %; (2) identifies rocks with high native Cl concentrations, which may be lower priority for 36Cl surface exposure dating, at an early stage of analysis; and (3) allows laboratory users to maintain control over the total chlorine content within and across analytical batches. These methods can be incorporated into existing laboratory and AMS protocols for 36Cl analyses and will increase the accessibility of 36Cl dating for geologic applications.

Published: August 2024

Background: Arab countries host 10% of all migrants globally. Migrant workers are known to have a high burden of physical and psychiatric morbidity. Most of the published literature on mental health among migrant workers is from non-Arab countries. The limited literature on migrant workers’ mental health in Arab countries is a critical research gap. It is pertinent to study well-defined migrant groups within well-defined host country conditions to yield pragmatic answers to inform service delivery.
Aims: The current study aims to complement existing data by characterizing psychiatric morbidity in a well-defined migrant group within a specifically defined context of migration.
Methods: Retrospective review of patient notes.
Results: All participants were men, and most of them were aged between 30 and 49 years. More than two-thirds presented with anxiety or depressive disorders. More than half had a past psychiatric history. Psychological distress was linked to stressors such as limited social support, living away from family, financial stressors, family-related stressors, and work-related stress. One-fourth of the participants reported stress related to the pandemic. Half of them reported physical health comorbidities. Two-thirds were not compliant with treatment plans, and one-fourth were lost to follow-up.
Conclusion: This is the first study to provide insight into the psychiatric morbidity of lower-skilled migrants presenting to outpatient psychiatry clinics in Qatar. The psychiatric morbidity of migrants is mainly centered around depressive and anxiety-related disorders. The most common challenges encountered in the management of patients include patient concordance with medication and loss to follow-up. Mitigation strategies are vital for ensuring the psychological well-being of migrant workers.
