Background: South Africa was the country worst affected by the Covid-19 pandemic in Africa. There is a paucity of data on the clinical characteristics and mortality of Covid-19 from the Eastern Cape province of South Africa. We report on the demographic and clinical characteristics as well as the mortality of patients admitted to the Covid-19 ward of Nelson Mandela Academic Hospital (NMAH), Mthatha, during three waves of the Covid-19 pandemic in South Africa.
Materials And Methods: We conducted a single centre retrospective observational study of patients admitted for Covid-19 in a tertiary hospital in the rural Eastern Cape of South Africa. Data were collected from patient files, electronic databases and the National Health Laboratory Services (NHLS) database. The outcomes were duration of admission and in-hospital mortality.
Results: There were 371 patients admitted across all three waves with a mean age of 52.2 ± 16.3 years. The proportion of females across the three waves is 61.2%. The commonly associated comorbidities, irrespective of the wave, were hypertension, diabetes and HIV infection. The median duration of admission was six days, with an overall mortality of 31%. The mortality for first, second and third wave were 29.3%, 31.5% and 37.9% respectively.
Conclusion: Admissions for Covid-19 were predominantly in females and middle-aged. One third of the admitted patients died. Diabetes, hypertension and HIV infection were the most commonly associated comorbidities.

Corrosion damage presents significant challenges to the safety and reliability of connected vehicles. However, traditional non-destructive methods often fall short when applied to complex automotive structures, such as bolted lap joints. To address this limitation, this study introduces a novel corrosion monitoring approach using Lamb wave-based weighted fusion imaging methods.

In composite structures, the precise identification and localization of damage is necessary to preserve structural integrity in applications across such fields as aeronautical, civil, and mechanical engineering. This study presents a deep learning (DL)-assisted framework for simultaneous damage localization and severity assessment in composite structures using Lamb waves (LWs). Previous studies have often focused on either damage detection or localization in composite structures.

Distributed feedback lasers, which feature rapid wavelength tunability, are not presently available in the yellow and orange spectral regions, impeding spectroscopic studies of short-lived species that absorb light in this range. To meet this need, a rapidly tunable laser system was constructed, characterized, and demonstrated for measurements of the NH radical at 597.4 nm.

The COVID-19 pandemic caused by the SARS-CoV-2 virus continues to circulate worldwide, causing the deaths of millions of people. The continuous circulation of the virus, its genetic diversity, the emergence of new variants with increased transmissibility, and/or the capacity of the virus to escape from the immune system constitute a major public health concern. In our study, we aimed to characterize SARS-CoV-2 strains in Iraq from the first introduction until the end of 2023, and to identify their variants, lineages, clades, and mutation patterns.

The most time-consuming aspect of dental prosthesis installation is the osseointegration of a metal implant with bone tissue. The acceleration of this process may be achieved through the use of extracorporeal shock wave therapy. The objective of this study is to investigate the conditions for osseointegration of the second premolar implant in the mandibular segment through the use of a poroelastic model implemented in the movable cellular automaton method.
