The severe acute respiratory syndrome coronavirus 2 is a novel coronavirus that causes the coronavirus disease 2019 (COVID-19). COVID-19 has been declared a pandemic by the World Health Organisation since March 2020. To date, the number of confirmed COVID-19 cases has exceeded 47 million and more than 1.2 million people have lost their lives to the disease. The disease is spreading at an exponential rate with no signs of slowing down. COVID-19 testing and early diagnosis play a crucial role in not just patient management, but also the prevention of the further spread of the disease. Various diagnostic approaches have been applied to detect SARS-CoV-2 infection. This article will critically review these diagnostic approaches and compare each with the gold-standard, which is viral RNA detection using reverse transcriptase-polymerase chain reaction (RT-PCR).

The coronavirus disease 2019 (COVID-19) is one of the biggest public health threats in the 21st century. Nearly every country in the world has been affected by COVID-19. The magnitude of the problem, with over 179 million confirmed cases and 3.8 million deaths worldwide, has driven researchers to search for vaccines to combat the disease. The discovery and development of a new vaccine, from the initial stage to the vaccine finally reaching the patients, usually take many years. However, given the urgency of the situation, many clinical trials on the COVID-19 vaccines have been conducted at extraordinary speed, whereas several vaccines against SARS-CoV-2 are being administered worldwide. This article gives an overview of the different types of COVID-19 vaccines, with a focus on those with promising results and are commonly used worldwide. It also gives an overview of herd immunity and discusses the challenges in achieving herd immunity through the global vaccination campaigns. Last but not least, some strategies that may be used to address these challenges are discussed.

BACKGROUND: Obesity in pregnancy causes both maternal and foetal complications hence adequate knowledge of obesity related pregnancy risks would ensure better outcomes. This study aims to determine the knowledge of obesity related pregnancy risks among pregnant women.

METHODS: A cross-sectional study was conducted among pregnant women from four antenatal clinics in Seremban, between February and May 2015. Knowledge on pregnancy risks was assessed using questionnaire. Women were defined as having broad knowledge on obesity related pregnancy risks if they correctly identified that women who are very obese, are at higher risk of obesity related pregnancy complications and weight loss prior to pregnancy is associated with lower risk of obesity related pregnancy complications. Descriptive statistics and regression tests were used in the analysis.

RESULTS: A total of 315 women participated in this study. Their mean age is 29.3 (SD±4.8) years and majority were Malay (72.4%). More than half of them were overweight and obese (60.6%). About 63.2% participants had broad knowledge on obesity related pregnancy risk. Education is a significant predictor of broad knowledge as women with tertiary education had higher odds of having broad knowledge compared to those with only school education (OR 2.1; 95%CI: 1.28 to 3.59).

CONCLUSIONS: This study found that more than half of the participants had knowledge of obesity related pregnancy risks and that education is a significant predictor for knowledge. Pre-pregnancy care education programmes can help identify barriers, introduce simple weight management strategies to overcome obesity, to ensure better maternal and foetal outcome.

PMID: 32860368

The commonest cause of dementia among the elderly population is Alzheimer's disease (AD). It is a health concern globally as the number of people affected by dementia worldwide is rapidly increasing. Several genes have been linked to AD and the pathogenesis of the disease has been extensively and vigorously examined. Thus far, only a few drugs have been approved by the Food and Drug Administration (FDA) for the pharmacological treatment of AD and a growing body of research has turned to alternative options such as stem cell therapy. This review will give an overview of the pathological and clinical aspects of AD. Although researchers have explored the suitability and feasibility of using various types of stems cells to treat AD, this review will focus mainly on neural stem cells (NSCs)/ neural progenitor cells (NPCs). The behaviour and properties of NSCs will be described, accompanied by a comprehensive discussion of the therapeutic strategies involving the use of NSCs/NPCs in the treatment of the disease.

Malays J Pathol, 2021 Aug;43(2):241-250.

PMID: 34448788

Ribonucleic acid (RNA) has been well-understood for its linear form for many years. With advances in high-throughput sequencing, there is an increasing focus on circular RNAs (circRNAs) recently. Although they were previously regarded as splicing error by-products, research has shown that they play a pivotal role in many cellular processes, one of which is the control of stem cell differentiation and fate. On the other hand, decades of research have demonstrated the promising therapeutic potential of mesenchymal stem cells (MSCs). To this end, there is a growing body of research on the role of circRNAs in the determination of the fate of MSCs. This review critically examines the current evidence and consolidates key findings from studies that explore the involvement of circRNAs in the regulation of MSC differentiation.

Therapeutic potential of mesenchymal stem cells and their derivatives in sarcopenia

PMID: 36591711

Sarcopenia is a common condition in the geriatric population. It refers to age-related and progressive decline in muscle mass and function, which has a great impact on one's mobility and quality of life. Patients with sarcopenia are mainly treated with nutritional therapy, exercise therapy, or a combination of both. Since the identification of mesenchymal stem cells (MSCs) several decades ago, many studies have explored the application of MSCs in the field of regenerative medicine. MSCs are popular candidates for cell-based therapy owing to their multipotent nature and immunomodulatory properties. Even though MSCs do not naturally differentiate into myogenic cells, they are important players in skeletal muscle health, as MSCs support myogenic differentiation of other cells and promote recovery of injured skeletal muscle. Recent studies have found that MSCs may be of benefits in the treatment of sarcopenia. This article gives an overview of sarcopenia and the role of MSCs in skeletal muscle homeostasis. It also discusses the therapeutic potential of MSCs and their derivatives, as well as the underlying mechanisms of the therapeutic effects of MSCs and MSC-based products in sarcopenia.

In Malaysia, where vaccination campaigns against foot-and-mouth disease and haemorrhagic septicaemia are routinely carried out, it was desirable to determine whether it was safe and efficacious to administer both vaccines simultaneously. A trial group of 104 cattle was divided into three groups; group 1 animals received both vaccines simultaneously, group 2 animals received only foot-and-mouth disease vaccine and group 3 animals received only haemorrhagic septicaemia vaccine. The serological response to vaccinations was monitored at 0, 21 and 35 days by the virus neutralisation test for foot-and-mouth disease and the mouse-protection and indirect haemagglutination tests for haemorrhagic septicaemia. The simultaneous administration of the two inactivated vaccines produced no adverse effects and the serological response did not differ from the response to either vaccine given separately, thus indicating that cattle may be safely and effectively vaccinated simultaneously in this way.

The global community faces critical energy and environmental challenges, necessitating innovative solutions to ensure a sustainable future.In response to these challenges, this paper explores the potential of integrating microalgal biotechnology with renewable energy systems within buildings. This innovative approach could transform architecture into a "bio-factory" capable of producing food, energy, and other valuable products.The success of this concept hinges on developing highly efficient photobioreactors specifically designed for building integration. Optimizing these systems requires careful consideration of design parameters, growth rate models, and factors influencing performance within diverse urban environments.Furthermore, integrating these systems must prioritize productivity and aesthetics to promote urban self-sufficiency and a sustainable built environment. By utilizing microalgae and renewable energy sources, building-integrated photobioreactors offer a promising solution for reducing energy consumption and carbon footprints in modern buildings.
