Authors: Wanok Godfrey , Arunga Simon , Dhillon Baljean , Nsubuga Naomi
Published: February 2025

Background: Keratoconus has a global prevalence of 0.2 to 4790 per 100 000 persons and there is currently no published report about its incidence, prevalence or the role of optometrists in its management in Uganda. This study looked at the role of optometrists in the diagnosis, management and referral of patients with keratoconus in Uganda.Aim: To determine the knowledge, experiences and practices of optometrists in the management of keratoconus in Uganda.Setting: This study was conducted in Uganda.Methods: Fifteen optometrists who had practiced for at least one year were recruited into the study, which was conducted in accordance with the International Conference on Harmonisation Tripartite Guideline for Good Clinical Practice. The study involved interviews that were conducted over zoom and telephones, which were considered for participants who had internet challenges. The sessions were recorded, transcribed verbatim, coded and themes were derived.Results: The median number of years of experience was 7 years. The participants’ experiences were reported in terms of diagnosis, management and referral of patients with keratoconus and common themes were explored. Retinoscopy and Munson’s sign were the most common diagnostic methods while spectacles were the most common management option used by the optometrists.Conclusion: Most optometrists relied on retinoscopy for diagnosis and spectacles for the management of keratoconus because of the lack of diagnostic equipment and challenges associated with contact lens practice in Uganda.Contribution: This is the first study to explore how keratoconus is managed by optometrists in Uganda and the results can be used to improve patient care in the country.
Homeomorphism groups of telescoping $2$-manifolds are strongly distorted
Authors: Vlamis Nicholas G.
Published: February 2025

Building on the work of Mann and Rafi, we introduce an expanded definition of a telescoping

2

-manifold and proceed to study the homeomorphism group of a telescoping

2

-manifold. Our main result shows that it is strongly distorted. We then give a simple description of its commutator subgroup, which is index one, two, or four depending on the topology of the manifold. Moreover, we show its commutator subgroup is uniformly perfect with commutator width at most two, and we give a family of uniform normal generators for its commutator subgroup. As a consequence of the latter result, we show that for an (orientable) telescoping

2

-manifold, every (orientation-preserving) homeomorphism can be expressed as a product of at most 17 conjugate involutions. Finally, we provide analogous statements for mapping class groups.

Authors: Ju Hyon Hui , Kim Chol San , Kim Jin Hyon
Published: February 2025

This paper establishes topological semi-conjugacy between a symbolic dynamical system

(\Sigma_{A},\sigma_{A})

and the system

(M(X),T_{M})

induced on the space of probability measures by a compact topological dynamical system

(X, T )

. Some conditions on an original system

(X,T)

are obtained for the induced system

(M(X),T_M)

to have a subsystem topologically semi-conjugate to

(\Sigma_{A},\sigma_{A})

, and some relations between an original system

(X,T)

and the induced system

(M(X),T_{M})

concerning semi-conjugacy to

(\Sigma_{A},\sigma_{A})

are given. By using these results, several criteria of Li–Yorke chaos and Devaney chaos for the induced system

(M(X),T_{M})

are established. Also, a characterization of the

\mathcal{F}

-mixing dynamical system

(X,T)

with Furstenberg family

\mathcal{F}

is obtained by means of the system

(M(X),T_{M})

, which gives an answer to the question posed by Fu and Xing [Chaos Solitons Fractals (2012), 439–443].

Children in low-resource settings often consume microbially contaminated food, risking their health. We evaluated the impact of a food hygiene intervention on complementary food contamination in Bangladesh. A 3-year homestead food production intervention was complemented by an 8-month behavior change module to improve household food hygiene practices and evaluated in a cluster-randomized controlled trial, including a dedicated study measuring outcomes along the hygiene pathway to intestinal health. We used multilevel regression to assess the intervention’s impact on microbial food contamination as well as food hygiene knowledge (n = 518) and reported practices (n = 531) among mothers of children 6–23 months of age. Complementary food samples were collected from 342 households with children 6–18 months of age and tested for Escherichia coli. Overall, 46% of food samples were contaminated with E. coli (43% intervention, 51% control), and there was no evidence that the intervention reduced food contamination (odds ratio: 0.65, 95% CI: 0.35–1.21). A higher proportion of intervention mothers could name all key food hygiene practices (23% intervention versus 1% control), had access to a basic handwashing station near the kitchen (24% versus 14%), reported washing hands before food preparation and child feeding (21% versus 8%), reported washing and storing feeding utensils safely (61% versus 49%), and reported preparing food fresh or reheating stored food (88% versus 79%) compared with control mothers. The intervention thus improved knowledge and reported food hygiene practices among mothers, but this improvement did not result in a substantial reduction of complementary food contamination.

The need for electricity is good for the industry, offices, and public and individuals are greatly increased. However, the increase in demand for electricity is not accompanied by the additional power supply. Based on these problems, chosen solar enersgy as an alternative energy to generate electric power. A tool that is used here is the solar cell because it can directly convert solar radiation into electrical energy (photovoltaic process). So that solar energy can be used at night, then during the day, the electrical energy generated is stored before a battery which is controlled by the regulator. Regulator output is directly connected to the inverter from the DC to AC. The test results of solar modules (photovoltaic) indicated that the results of the average power output reached 38.24 Watt, and the currents were 2.49 A. This is because the photovoltaic follows the direction of movement of the sun and always located at the photovoltaic to remain facing the sun. Therefore, it will still be able to capture the radiant sun to the fullest.

Dengue fever, a widespread arboviral infection, ranges in severity from mild febrile illness to life-threatening conditions such as dengue hemorrhagic fever and dengue shock syndrome. Rarely, dengue can precipitate hemophagocytic lymphohistiocytosis (HLH), a severe hyperinflammatory syndrome characterized by dysregulated macrophage and T-cell activation. We report a case of a 45-year-old female presenting with fever, hepatosplenomegaly, cytopenias, and hyperferritinemia, who was diagnosed with dengue-associated HLH. The diagnosis was established using clinical findings, elevated ferritin, cytopenias, splenomegaly, and hemophagocytosis in the bone marrow, fulfilling the HLH-2004 criteria. Early initiation of dexamethasone, along with supportive therapy, improved the patient’s clinical status. This case underscores the importance of increased clinical vigilance for HLH in dengue patients with rapid clinical deterioration. Early diagnosis and prompt immunomodulatory therapy can significantly improve outcomes. Further research is needed to better understand the pathophysiology, diagnostic challenges, and optimal treatment strategies for dengue-associated HLH.
An Explainable Artificial Intelligence (XAI) Methodology for Heart Disease Classification
Authors:   Administrative and Financial Department, Ministry of Higher Education and Scientific Research, Baghdad 10001, Iraq, Yaseen Omar Mahmood
Published: February 2025

Heart disease continues to be one of the predominant contributors to morbidity and mortality on a global scale, underscoring the imperative for early and precise diagnosis to enhance patient outcomes. Machine Learning (ML) has emerged as a formidable instrument in the classification of cardiovascular diseases, utilizing intricate clinical datasets to discern patterns that conventional statistical methodologies may fail to detect. Nevertheless, notwithstanding their robust predictive capabilities, numerous machine learning models function as black-box systems, exhibiting a deficiency in transparency regarding their decision-making processes. The absence of interpretability presents a considerable challenge in clinical environments, where trust, accountability, and elucidation are of utmost importance for medical professionals. In order to tackle this issue, we propose a methodology for heart disease classification that is grounded in Explainable Artificial Intelligence (XAI). This approach incorporates interpretable machine learning models to improve diagnostic transparency and reliability. Our framework conducts an evaluation of various classifiers, including Support Vector Machine (SVM), Gradient Boosting (GB), Extreme Gradient Boosting (XGBoost), Multi-Layer Perceptron (MLP), and LightGBM. This assessment is based on essential performance metrics, namely accuracy, precision, recall, F1-score, and AUC-ROC. Furthermore, SHAP (SHapley Additive exPlanations) and LIME (Local Interpretable Model-Agnostic Explanations) have been integrated to enhance the interpretability of the model. The experimental findings indicate that XGBoost surpasses alternative models, attaining the highest classification accuracy of 92% and an AUC-ROC score of 0.93, all while preserving interpretability. This study underscores the significance of incorporating Explainable Artificial Intelligence (XAI) techniques within medical AI applications. It advocates for the adoption of transparent, interpretable, and clinically dependable machine learning methodologies to enhance clinical decision-making and optimize patient outcomes.

Background: Prolonged postprandial hyperlipemia (PPL) and hyperglycemia (PPG) are important risk factors for the development of cardiovascular disease. Although physical exercise improves lipid profile and glucose tolerance, thus reducing cardiovascular risk, the effects of fasting exercise in adolescents need to be investigated. Objective: To investigate the effects of different intensities of fasted aerobic exercise on the magnitude of PPL and glycemic responses to isocaloric meals in adolescents. Methods: A randomized crossover clinical trial in which 13 healthy and eutrophic adolescents, aged 14.5 ± 1.3 years, performed three interventions (washout period = 7 days): 45 minutes of rest (REST); 45 minutes of moderate-intensity fasting (MI); and a calorie-matched high-intensity aerobic exercise session (HI). Subjects were serially assessed for blood triglycerides, cholesterol, and glucose levels. Results: Regarding PPL, the MI protocol induced triglycerides reductions compared to REST only at 105 min (70.1 ± 10.3 vs 95.4 ± 30.2; p=0.006) and compared to both HI and REST at 135 min (68.4 ± 14.4 vs 91.5 ± 24.9 vs 93.7 ± 21.2 p<0.02). No differences in iAUC were observed. Conclusion: The present study shows that calorie-matched moderate and high-intensity fasting aerobic exercise has no acute effect on PPL responsiveness in adolescents.

Is Kidney Trading the Answer for Kidney Shortage? A Case Study Based on Iran’s Experience
Authors:   St. John’s School, Guam, Liu Claire
Published: February 2025

Kidney transplantation has been demonstrated to be the treatment of choice for end stage renal disease. However, most patients still end up receiving dialysis
rather than receiving transplantation for the kidney as the organ source is fairly limited in most countries. We therefore explore the case of Iran where kidney
trading is considered legal. As of now, Iran is also the only country worldwide that allows monetary compensation for kidney donation, whereas there are
rules to refrain its abuse. We also discuss the strength and weakness of Iran’s kidney trading system and the applicability of the system to other countries
to hopefully help reduce the kidney shortage in organ donation

Background: Proficiency in psychomotor skills is crucial for medical interns transitioning from theoretical
knowledge to practical application. Traditional teaching methods often lack sufficient hands-on experience
and critical feedback, resulting in procedural errors and increased healthcare costs. This study evaluates the
effectiveness of the Demonstrate-Observe-Assist-Perform (DOAP) method in teaching urinary male bladder
catheterization (MBC).
Methods: A clinical descriptive longitudinal study was conducted with 40 intern doctors. Participants were
initially assessed on traditional urinary catheterization method in male patients. The DOAP method was then
employed, involving demonstration, observation, assistance and supervised performance. After three weeks
of training and supervised performance, participants were re-evaluated using direct observation of procedural
skills (DOPS) method with checklists and questionnaires tool. Statistical analysis performed and compared preand post-training proficiency.
Results: Significant improvements were observed post-DOAP training. Awareness of critical steps increased from
67.5% to 97.5% (p=0.001), confidence in performing MBC rose from 70% to 95% (p=0.003) and understanding
of the 'No Touch technique' improved from 82.5% to 100% (p=0.012). Faculty evaluations showed enhanced
ability to perform MBC with all critical steps from 20% to 82.5% (p=0.000) and increased counselling skills from
52.5% to 92.5% (p=0.000).
Conclusion: The DOAP method significantly enhances the psychomotor skills of intern doctors, improving both
knowledge, practical performance and communication skills. Integrating DOAP into medical training programs
is recommended to enhance clinical competence and patient care quality.

Published: February 2025

A piomiosite é uma infecção bacteriana aguda rara que afeta o músculo e evolui para abscessos, tendo como principal agente etiológico o Staphylococcus aureus. Ela acomete, em sua maioria, crianças e adultos jovens, bem como imunocomprometidos. O diagnóstico necessita de suspeita clínica, podendo ser confirmado por exames de imagem. O tratamento é feito com antibioticoterapia, associada ou não a abordagem cirúrgica. Embora sua incidência ainda esteja muito associada a regiões tropicais, é um diagnóstico que deve ser pensado, dada sua potencial gravidade evolutiva. Dessa forma, este estudo buscou relatar um caso de piomiosite em paciente escolar internado em hospital municipal, cujas informações foram obtidas através da revisão do prontuário, entrevista com o paciente e seu acompanhante, e revisão da literatura.

A síndrome nefrótica (SN) é caracterizada por proteinúria, hipoalbuminemia, edema e hiperlipidemia, decorrente do aumento da permeabilidade da membrana basal glomerular. Pode ser dividida em secundária, quando causada por alguma outra doença, ou primária (idiopática). O prognóstico em longo prazo tem melhor correlação com a resposta à terapia com glicocorticoide e raramente evoluem para insuficiência renal. A identificação de fatores de risco e da doença em seu estágio inicial e o encaminhamento ágil e adequado para o atendimento especializado, garante melhor resultado terapêutico e prognóstico dos casos. Este artigo apresenta um relato de caso clínico de uma paciente com síndrome nefrótica idiopática. Neste trabalho, evidencia-se a necessidade de acompanhamento logo nos primeiros sinais e sintomas clínicos com exames complementares. O paciente foi encaminhado ao ambulatório de nefrologia pediátrica e cardiologia pediátrica e segue até o presente momento em seguimento ambulatorial.

PERCEPTION OF GRADUATING STUDENTS ON NEPOTISM IN GOVERNMENT EMPLOYMENT
Authors: Khalid Butt Qasim
Published: February 2025

This study examines the perception of graduating students from the Baguio Central University in the Philippines towards nepotism in government employment. Adopting a quantitative, descriptive research design with survey methodology, the study examines the occurrence of nepotism, its perceived influence on career aspiration among students. The research indicates that the graduating students view nepotism as being very serious, eroding public confidence in government institutions and discouraging qualified people from joining the public service. The research indicates that government agencies should fight nepotism through enhanced anti-nepotism policies, educational campaigns, and independent hiring committees to advance merit-based hiring and prevent favoritism in the employment of government officials.

The COVID-19 pandemic due to the SARS-CoV-2 coronavirus has vastly impacted our national health and economic industries. Hence, the utilisation of big data simulation of the outbreak is essential to guide policymakers, government, and health authorities in better understanding the dynamics of the infectious disease. This paper integrates the Agent-Based-Model (ABM) and Susceptible, Exposed, Infectious and Recovered (SEIR) framework to understand the dynamic transmission of COVID-19 in Sabah, Malaysia. This study employed NetLogo software, which includes parameters such as geographical distribution, population density, variant type, lockdown measures, and vaccination rates across 27 districts, to run the simulation and assess the potential impact of public health interventions. The methodology involves different scenario simulations using varying variant types, vaccination coverage, lockdown, and social distancing measures to determine the virus transmission level. The results indicate that higher vaccination coverage and strict adherence to preventive measures can reduce the spread of the virus, especially in highly densely populated areas. Our simulation resulted in a 2.54% variance with the true data following the parameters and settings mentioned above. Additionally, this study also found that geographical structure and uneven distribution of healthcare across the Sabah district notably affect disease and disaster management and intervention policy and efficacy. These insights are crucial for Malaysian policymakers and health authorities, which need to tailor the public health responses considering geographical and demographic settings. Future recommendations include data of higher geographical resolution, immunisation records, and real-time mobility data to portray a more realistic simulation.
Temperature-corrected Performance Ratio of Grid-Connected Photovoltaic System: Tropical versus Continental Climate

Performance ratio (PR) is often used as a performance metric in commercial acceptance tests of an installed grid-connected photovoltaic (GCPV) system. Recently, PR has been claimed to significantly affect seasonal and weather variations, which would invite unnecessary risk to the commercial acceptance test. In the updated IEC 61724-1, the temperature-corrected performance ratio (TCPR) has been included as the performance metric to remove the seasonal and weather variations. However, not all climate regions experience these variations, which means that TCPR might not be necessary for certain climate regions. Due to that, this study aims to analyse the relevancy of determining TCPR in addition to the normal PR for GCPV systems for different climate regions. The analysis was conducted using PVsyst software by comparing the PR and TCPR of two similar GCPV systems: case A represents tropical climate and case B represents continental climate. The results evidently show that the PR and TCPR values are always very close for both climate regions if analysed annually. However, when analysed monthly, the normal PR varied significantly between 77.5% and 90.0%, indicating a 12.5% difference for continental climate, but for tropical climate, the difference is just 1.0%. Conversely, the monthly TCPR variation in the continental climate is insignificant, with the value ranging from 81.4% to 84.1%, indicating only a 2.7% difference. Thus, the results of this study suggest that both PR and TCPR are relevant for continental climate. However, normal PR alone is already sufficient for tropical climate as the performance metric.

A polymer Gel Dosimeter (PGD) provides essential three-dimensional (3D) radiation dose distribution for the radiotherapy planning system (TPS). This study investigates the use of infrared absorption spectrum as a novel and more cost-effective alternative to Magnetic Resonance Imaging (MRI), Nuclear Magnetic Resonance (NMR), and Optical Computed Tomography (Optical CT) for reading out PGDs. The PGDs were fabricated using 2-Hydroxyethyl methacrylate (HEMA), maltose, N’N, methylene(bis)acrylamide (Bis), gelatin, deionized water (DI Water), and Tetrakis (hydroxymethyl) phosphonium chloride (THPC), and were irradiated using a Linear Accelerator (LINAC) within the range of 0–30 Gy. The possibility of translating molecular vibrational frequency, amplitude, and energy of vibration into absorbed dose was explored by analyzing the absorption spectra in the near-infrared region (NIR) with wavelengths between 750–1100 nm. The findings reveal that these vibrational properties can be employed to interpret irradiated PGDs. Furthermore, an increase in maltose concentration within the 0–520 mM range widens the linear dose range and enhances sensitivity. The PGDs exhibit temporal stability up to 7 days post-irradiation, and the span of their response remains relatively unaffected by scanning temperature. In conclusion, NIR spectroscopy offers a cost-effective method for interpreting PGDs, potentially improving the affordability and efficiency of PGD dosimetry in clinical radiotherapy. This holds particularly promising for less developed countries, aligning with the sustainable development goal (SDG) of ensuring affordable healthcare for all. We finally recommend further research into translating the molecular vibrational parameters into 3D images.
