The national progression policy in Gauteng schools: Is the policy failing progressed learners?
Authors: Erasmus Gene , Fourie Jean V. 
Published: December 2024

ackground: The National Policy Pertaining to Programme Promotion Requirements (NPPPR) allows learners to repeat 1 year per phase. However, problematic policy implementation is indicated by the large numbers of unsupported progressed learners in schools, leading to unmanageable peer group dynamics and compromised educational outcomes.Aim: To analyse and explain the status of the NPPPR regarding progressed learners in the Gauteng province.Setting: The study was conducted in a Gauteng Education District from 2017 to 2019. Learners from all primary and secondary schools and all grades were included. Schools were located in townships and urban areas.Methods: Quantitative data were collected, with purposive, non-probability sampling, in an education district, comprising 187 schools (6% of the Gauteng province, n = 407 347 learners). Data were collected on learner ages, grades and number of years progressed, from the Department of Education database. Descriptive statistics determined means, modes and frequencies.Results: An increase in progressed learner numbers from 2017 to 2019 was seen, with most progressed learners in township, quintile 1–3, secondary schools, in the senior phase, and being males. Numbers declined in Grades 10 and 11.Conclusion: Large numbers of progressed learners in Grades 8 and 9 lead to over-aged learners, overcrowded, unmanageable classrooms and overworked teachers.Contribution: Valuable quantitative statistics on progressed learners allowed critique of the inconsistent implementation of the NPPPR policy which results in social and behavioural problems for teachers. This study contributes to creating an awareness of policy circumvention resulting in overburdened schools.

Published: December 2024

ABSTRACT
Post-COVID-19 infections present with diverse manifestations, and cavitary lesions, including Rasmussen’s aneurysm, can occur, particularly in immunocompromised individuals. We present a case study of a 62-year-old post-COVID-19 patient with cavitary consolidation and Rasmussen’s aneurysm due to invasive Aspergillus infection. Despite antifungal treatment, the patient experienced massive hemoptysis, leading to circulatory collapse and an unfortunate outcome. Pulmonary manifestations post-COVID-19 are varied, including lung fibrosis, vascular diseases, and secondary infections. Cavitary lesions, although infrequent, can lead to complications such as Rasmussen’s aneurysm, emphasizing the need for early diagnosis and prophylactic management to prevent life-threatening episodes of hemoptysis. This case highlights the importance of recognizing cavitary and cystic air spaces in post-COVID-19 pneumonia and the potential catastrophic consequences of delayed diagnosis.
Percutaneous transcatheter occlusion of large pulmonary arteriovenous fistula with Amplatzer Septal Occluder in a young cyanotic girl
Authors: Kumar K. Arun , Ghosh Soumik , Awasthy Neeraj , Shankar Om 
Published: December 2024

ABSTRACT
For most instances, percutaneous transcatheter intervention has replaced surgical procedure as the preferred treatment for pulmonary arteriovenous fistulas (PAVFs). Despite its efficacy in interventional occlusions of small- to medium-sized PAVFs, “classic” devices such as detachable balloons and intravascular coils are not recommended for bigger fistulas due to the potential risk of embolization to the systemic circulation. This case report is a unique case of a 17-year-old cyanotic girl who had a large symptomatic solitary PAVF that was effectively closed with a 26 mm Amplatzer Septal Occlude (ASO) device. The PAVF was located in the lower right lobe of the lung. The position of the device in situ occluding the feeding channel was verified by computed tomography pulmonary angiography and postprocedure echocardiography, which also revealed the obliteration of the right-to-left shunt.

ABSTRACT

Background:
Epidemiological transition is leading to an increased burden of cardiovascular disease among rural populations.

Aim:
The study evaluated the etio-clinical profile, prevalence, angiographic characteristics, and correlates of inferior wall myocardial infarction (IWMI).

Materials and Methods:
This was an institution-based, cross-sectional study among 103 consecutive patients. Regression analysis was done to find the correlates of IWMI.

Results:
The mean age was 59.14 ± 11.65 years. The study consisted of 86.4% males. 86 (83.5%) were smokers and 12 (11.7%) were alcoholics. 30 (29%) were hypertensive and 33 (32%) were diabetic. 41 (39.8%) had a family history of hypertension and an abnormal lipid profile. The mean body mass index was 23.09 ± 3.62 kg/m2. The mean systolic blood pressure and diastolic blood pressure were 127.23 ± 30.71 mmHg and 77.98 ± 15.83 mmHg, respectively. 4 (3.9%) had COVID-19 disease and 102 (99%) were vaccinated for it. The total occlusion of the vessel was found among 71 (68.9%) subjects. Single-vessel disease was the most prevalent condition – 39 (37.9%). Proximal site occlusion was found among 62 (60.2%) of subjects. Sinus bradycardia was present among 44.7% of subjects. Age (adjusted odds ratio [aOR] =0.89, 95% CI: [0.82–0.97]), COVID-19 disease (aOR =0.011, 95% CI: [2.11e–0.58]), history of hypertension (aOR =11.18, 95% CI: [1.25–99.65]), and sinus bradycardia (aOR =10.41, 95% CI: [1.22–88.63]) were significant predictor of inferior wall ST-segment elevation myocardial infarction (IWSTEMI). The most frequent complication was rhythm disturbances.

Conclusion:
More than four of five were smokers and rhythmic disturbances were present in nearly one-fifth of subjects. Young age, male sex, hypertension, COVID-19 disease, and sinus bradycardia were significant predictors of IWSTEMI.

ABSTRACT

Background:
Subclinical hypothyroidism (SCH) is defined as a state of increased serum thyroid-stimulating hormone (TSH) level with circulating thyroxine (T4) and triiodothyronine (T3) in the population reference range. Patients with SCH have an increased risk of subclinical cardiac dysfunction and dyslipidemia.

Objective:
The primary objective was to assess the left ventricular myocardial performance index (MPI), i.e., the Tei index which is a marker of global MPI in subclinical hypothyroid patients. There were two secondary objectives. The first was to assess the correlation between Left ventricle (LV) Tei index and serum TSH level in patients with SCH. The second was to measure the atherogenic index of plasma (AIP) in patients with SCH and it is correlation with the Tei index.

Materials and Methods:
This was a cross-sectional, observational study including 100 subclinical hypothyroid patients. All subclinical hypothyroid patients attending outpatient department underwent screening, detailed history taking, and clinical examination. Patients were analyzed for eligibility of the study. After taking consent, all eligible patients underwent tests for routine blood sampling, lipid profile, thyroid profile, antithyroid peroxidase antibodies, electrocardiography, and echocardiography including tissue Doppler imaging. MPI was calculated for each patient. MPI was correlated with serum TSH levels and also with atherogenic plasma index (AIP) using an appropriate statistical analysis tool.

Results:
Fifty-three percent of subclinical hypothyroid patients had abnormal lateral and medial Tei index. Fifty-one percent of subclinical patients had abnormal mean Tei index despite normal left ventricle ejection fraction. However, there was no correlation between the Tei index and TSH level. In this study, 48% and 29% of patients had high and intermediate cardiovascular risk, respectively, according to AIP. No statistically significant correlation was observed between the Tei index and atherogenic index of plasma.

Conclusion:
Subclinical hypothyroid patients have significant subclinical cardiac dysfunction (as determined by the Tei index) and dyslipidemia. AIP may serve as an effective screening method to identify subclinical hypothyroid individuals who are at higher risk of cardiovascular events. Large prospective studies are needed to validate the AIP-TSH-MPI relationship.

Published: December 2024

ABSTRACT
Cardiovascular diseases often present clinicians with a myriad of challenges, and within this spectrum, the occurrence of left ventricular (LV) clot formation remains a relatively common phenomenon. We present a singular case that challenges conventional assumptions about LV clot formation. The patient’s clinical history, diagnostic workup, and management course converge to create a compelling narrative that not only underscores the uniqueness of this case but also sheds light on potential factors that may contribute to the diagnosis of LV clots in unexpected contexts and the usefulness of multimodality imaging in this case. Through a detailed exploration of this uncommon case, we aim to contribute to the existing body of knowledge, providing insights that may guide future clinical practice and research. By presenting this exceptional case, we hope to foster a deeper understanding of the complexities surrounding LV clot formation and its implications for patient care. We present a case of a young adult patient presented with an ischemic cerebrovascular accident (CVA). He was on treatment for that as single antiplatelet and statin. He was evaluated for young CVA by the neurology department and he was referred for cardiac evaluation to rule out the cardioembolic stroke. This case report highlights an exceptional instance of LV clot formation in a young patient without the common predisposing factors typically associated with such a condition. This case also underscores the critical role of advanced imaging techniques in identifying and managing atypical presentations of LV clots.

Published: December 2024

Abstract
Hepatitis D virus (HDV) prevalence data and country-specific HDV guidelines are not widely available in the Gulf Cooperation Council (GCC) states. We developed consensus recommendations to guide healthcare professionals, policymakers, and researchers in improving HDV management and patient health outcomes in three GCC states: Kuwait, Saudi Arabia, and the United Arab Emirates. A consensus panel comprising hepatology experts (n = 6) from the three GCC societies was formed. The panel identified two broader areas related to clinical practice (screening and diagnosis, and treatment and management), addressed critical questions, and developed draft recommendations in February 2024. The strength of the final set of recommendations was subjected to consensus voting in March 2024. A majority was defined a
priori with a two-thirds vote (67%). The paper outlines those recommendations alongside showcasing the current epidemiology of HDV in the GCC states, emphasizing the variability in prevalence, demographic patterns, and region-specific risk factors. It also highlights the current state of screening and diagnosis practices, identifying key obstacles, such as access to advanced screening protocols and diagnostic tools. Furthermore, HDV treatment landscape and preventative strategies are outlined, focusing on vaccination, public health initiatives, and the crucial role of public awareness and education. Ethical and sociocultural considerations are discussed, underscoring the importance of culturally sensitive healthcare practices. These recommendations present a comprehensive overview of the challenges and strategies for managing HDV in these states. Policy recommendations are provided to support HDV management, including standardizing care protocols and promoting public health measures.

Banks are vulnerable to the risk of bad credit or default because customers are unable to pay their debts. Risks that may occur in the future can be in the form of unexpected events and can be experienced by anyone, causing the loan to not be fully repaid. Therefore, it is necessary to have insurance to overcome risks due to default in protecting oneself from the risk of unexpected events, namely credit insurance. This study aims to calculate the premium price using the Black-Scholes-Merton model approach. The data used is arrears data of customers PD. Bank Perkreditan Rakyat (BPR) Artha Sukapura in 2003-2020. The data is compiled into a cumulative relative frequency distribution table, resulting in a number of random numbers. Based on the cumulative relative frequency distribution table, data simulation was determined using Monte Carlo. Based on the results of the analysis, the simulation data obtained by the standard deviation are relatively stable and lognormal distributed. Then pricing is done to determine the premium price from the sample data. From the results of the calculations in this study, a premium value of Â was obtained for arrears of Â with a loan of .
Factors Affecting Romantic Relationship in Lebanon

Published: December 2024

The concepts of romance and love are rapidly evolving with new modalities of romantic relationships in Lebanon (civil marriage, cohabitation) along with a catastrophic economic crisis affecting the country since 2019, and being ranked among the top ten crises worldwide. This document represents a cross-sectional study investigating 585 Lebanese participants from different Lebanese regions randomly sampled using the snowball method. Besides, the Relationship dynamics scale (RDS) was used to evaluate vulnerability for conflicts in the context of romantic relationship and their correlates, with a very good internal consistency (Cronbach’s Alpha of 0.908) and an excellent validity (Factor analysis using Promax technique). The results are as follows: A higher vulnerability for conflicts in the context of amorous relations is associated with having a child or a partner with handicap or receiving an actual chronic treatment (personal, for children or for the partner), having 3 or more children and finally having high financial stressors. Moreover, this survey evaluated factors modulating financial burden and stress using the InCharge Financial Distress / Financial Well-Being (IFDFW) scale. The results showed that working only with day shifts schedule, being male, having physical activity of a minimum of 2.5 hours per week, having a partner working outside Lebanon, having an income in currency other than Lebanese Pound, and being married at an age above 30 years are associated with less stressful economic status. While on the other hand, having a history of chronic treatment (Personal, Partner or children) and being married before 18 years were correlated with high levels of economic stress.
