National HIV programme testing recommendations.

In recognition of the morbidity and mortality associated with human immunodeficiency virus (HIV), the Joint United Nations Programme on HIV/acquired immunodeficiency syndrome (AIDS) (UNAIDS) aims to end the epidemic by setting and striving to achieve the ambitious 95-95-95 targets. However, Singapore is still not performing well in the first UNAIDS target. The National HIV Programme (NHIVP) developed this set of recommendations based on an adaptation of major international guidelines from the World Health Organization and the US Centers for Disease Control and Prevention.

Same-day and rapid initiation of antiretroviral therapy in people living with HIV in Asia. How far have we come?

Human immunodeficiency virus (HIV) continues to be a major public health issue, and the effectiveness of HIV prevention, diagnosis, treatment, and care varies, particularly in the Asia-Pacific region. The rapid initiation of antiretroviral therapy (ART) is important to control the HIV epidemic and to optimize the health of people living with HIV; many guidelines now recommend ART initiation within 7 days of HIV diagnosis, with same-day initiation for people diagnosed with HIV who feel ready. Many countries in the Asia-Pacific region have already implemented or are moving towards implementation of rapid or same-day ART initiation.

Recommendations for the use of antiretroviral therapy in adults living with human immunodeficiency virus in Singapore.

Since the advent of combination antiretroviral therapy (ART), the mortality attributable to human immunodeficiency virus (HIV) infection has decreased by 80%. Newer antiretroviral agents are highly efficacious, have minimal side effects as compared to older drugs, and can be formulated as combination tablets to reduce patients' pill burden. Despite these advances, 680,000 people worldwide died of acquired immunodeficiency syndrome-related illnesses in 2020.

Responding to COVID-19: how an academic infectious diseases division mobilized in Singapore.

Background: On January 30, COVID-19 was declared a Public Health Emergency of International Concern-a week after Singapore's first imported case and 5 days before local transmission. The National University Hospital (NUH) is Singapore's third largest hospital with 1200 beds, heavy clinical workloads, and major roles in research and teaching.

Main Body: With memories of SARS still vivid, there was an urgent requirement for the NUH Division of Infectious Diseases to adapt-undergoing major reorganization to face rapidly changing priorities while ensuring usual essential services and standards.

Challenges of hemodialysis in Vietnam: experience from the first standardized district dialysis unit in Ho Chi Minh City.

Background: Hemodialysis is an increasingly common treatment in Vietnam as the diagnosis of end stage renal disease continues to rise. To provide appropriate hemodialysis treatment for end-stage renal disease patients, we conducted a 1-year cross-sectional study to measure the prevalence of bloodborne infection and factors associated with non-compliant behaviors in hemodialysis patients.

Methods: One hundred forty-two patients were tested for hepatitis B virus (HBV) surface antigen and hepatitis C virus (HCV) core antigen.

Hepatitis B and C virus infections among patients with end stage renal disease in a low-resourced hemodialysis center in Vietnam: a cross-sectional study.

Background: Hemodialysis services in Vietnam are being decentralised outside of tertiary hospitals. To identify the challenges to infection control standards for the prevention of bloodborne infections including hepatitis B virus (HBV) and hepatitis C virus (HCV) we tested the magnitude of HBV and HCV infections in the largest unit in Ho Chi Minh City servicing patients with end stage renal disease.

Methods: All 113 patients provided consent HBV surface antigen (HBsAg) and HCV core antigen (HCV-coreAg) testing.

When traditional model meets competencies in Singapore: beyond conflict resolution.

Introduction: The implementation of competency-based internal medicine (IM) residency programme that focused on the assurance of a set of 6 Accreditation Council for Graduate Medical Education (ACGME) core competencies in Singapore marked a dramatic departure from the traditional process-based curriculum. The transition ignited debates within the local IM community about the relative merits of the traditional versus competency-based models of medical education, as well as the feasibility of locally implementing a training structure that originated from a very different healthcare landscape. At the same time, it provided a setting for a natural experiment on how a rapid integration of 2 different training models could be achieved.

Surface modification of silicone for biomedical applications requiring long-term antibacterial, antifouling, and hemocompatible properties.

Silicone has been used for peritoneal dialysis (PD) catheters for several decades. However, bacteria, platelets, proteins, and other biomolecules tend to adhere to its hydrophobic surface, which may lead to PD outflow failure, serious infection, or even death. In this work, a cross-linked poly(poly(ethylene glycol) dimethacrylate) (P(PEGDMA)) polymer layer was covalently grafted on medical-grade silicone surface to improve its antibacterial and antifouling properties.

Effect of IC14, an anti-CD14 antibody, on plasma and cell-associated chemokines during human endotoxemia.

To determine the role of CD14 in lipopolysaccharide (LPS)-induced release of chemokines, 16 humans were injected with LPS (4 ng/kg) preceded (-2 h) by intravenous IC14, an anti-human CD14 monoclonal antibody, or placebo. LPS elicited increases in interleukin (IL)-8 concentrations in plasma and in lysates of red blood cell (RBC), polymorphonuclear cell and mononuclear cell fractions, which were all reduced by IC14. LPS also induced rises in the plasma and RBC levels of monocyte chemoattractant protein (MCP)-1, which were diminished by IC14.

Anti-inflammatory effects of a p38 mitogen-activated protein kinase inhibitor during human endotoxemia.

The p38 mitogen-activated protein kinase (MAPK) participates in intracellular signaling cascades resulting in inflammatory responses. Therefore, inhibition of the p38 MAPK pathway may form the basis of a new strategy for treatment of inflammatory diseases. However, p38 MAPK activation during systemic inflammation in humans has not yet been shown, and its functional significance in vivo remains unclear.
