Human resource planning in healthcare can employ machine learning to effectively predict length of stay recruited health workers who are stationed rural areas. While prior studies have identified a number demographic factors related general practitioners' decision public practice, recruitment agencies no validated methods how long these will commit their placement. We aim use professional's practice the sector based on information. Recruitment and retention data from Africa Health Placements...
This qualitative study aimed to investigate the barriers that hinder men's utilisation of healthcare services in Sedibeng district South Africa.
The COVID-19 pandemic disrupted immunisation programs worldwide, reversing gains that had brought vaccine-preventable diseases largely under control. This study explored the impact of on uptake routine child services in South Africa.
In positron emission tomography acquisition (PET), sensitivity along a line of response can vary due to crystal geometrical arrangements in the scanner and/or detector inefficiencies, leading severe artefacts reconstructed image. To mitigate these effects, data must be corrected by set normalization coefficients applied each response. The J-PET Modular is PET device made 50 cm long plastic strips arranged axially, currently operation at Jagiellonian University Krak\'ow (Poland). We have...
There has been growing interest in understanding the drivers of health outcomes, both developed and developing countries. The on other hand, are factors that influence likelihood experiencing positive or negative outcomes. Human Immunodeficiency Virus (HIV) continues to be a significant global public challenge, with an estimated 38 million people living aim this study was therefore develop empirically test conceptual research model using SEM, aimed at explaining magnitude various influencing...
In addition to the direct health and economic impacts of COVID-19 pandemic, routine immunization children for vaccine-preventable diseases has also suffered. Quantitative studies have shown evidence backsliding in immunization, i.e., failing receive their vaccinations on schedule. Pandemic restrictions were cause some this behavior, there are signs that subsequent campaigns supply-side initiatives influenced trends toward catch-up. However, limited qualitative research indicates pandemic may...
Background: The COVID-19 pandemic disrupted immunisation programmes worldwide, reversing gains that had brought vaccine-preventable diseases largely under control. This study explored the impact of on uptake routine child services in South Africa.Methods: We conducted qualitative research using in-depth interviews with 51 randomly selected parents/caregivers children below age five who missed or delayed one more scheduled doses 2020-2022 and 12 healthcare providers provided public during...

Studies based on imaging the annihilation of electron (e$^{-}$) and its antiparticle positron (e$^{+}$) open up several interesting applications in nuclear medicine fundamental research. The process involves both direct conversion e$^{+}$e$^{-}$ into photons formation their atomically bound state, positronium atom (Ps), which can be used as a probe for studies. With ability to produce large quantities Ps, manipulate them long-lived Ps states, image annihilations after free fall or passing...
Positronium Imaging is gaining interest as a new promising method that may improve the diagnostic specificity of Positron Emission Tomography. Recently, first ex-vivo and in-vivo positronium lifetime images were demonstrated by means dedicated multi-photon J-PET system. The latest upgrades Biograph Vision Quadra (Siemens Healthineers) to singles mode acquisition open possibility imaging. In this simulation-based work, sensitivity both systems has been assessed function energy window applied...
The Modular J-PET scanner, developed by the collaboration, is a new prototype PET scanner based on axially arranged plastic scintillators as large axial field of view (50cm) affordable tomograph. In this study, performance characteristics were evaluated according to NEMA NU2-2018 standards using Monte Carlo simulation. order ensure selection true coincidence events, certain criteria established. Specifically, each photon emitting from single annihilation must deposit at least 200 keV within...
The Jagiellonian PET scanner is a cost-effective large axial FOV Positron Emission Tomography technology that enables multi-photon imaging and currently under development at the University. current 50 cm prototype, named "Modular J-PET", being investigated for various applications. It well known data can be affected by several effects during acquisition, such as scattered gamma photons or variations in detection efficiency. Consequently, achieving reconstruction of images satisfactory...
