Antimicrobial resistance has become increasingly dire as the rapid emergence of drug resistance, especially gram-negative pathogens, has outpaced the development of new antibiotics. At a recent virtual symposium, Dr Hsu Li Yang, Vice Dean (Global Health) and Programme Leader (Infectious Diseases), NUS Saw Swee Hock School of Public Health, presented epidemiological data on multidrug-resistant (MDR) gram-negative bacteria (GNB) in Asia, while Dr Tan Thuan Tong, Head and Senior Consultant, Department of Infectious Diseases, Singapore General Hospital (SGH), focused on the role of ceftazidime-avibactam in MDR GNB infections. Dr Andrea Kwa, Assistant Director of Research, Department of Pharmacy, SGH, joined the panel in an interactive fireside chat, to discuss challenges, practical considerations, and solutions in MDR gram-negative infections. This Pfizer-sponsored symposium was chaired by Dr Ng Shin Yi, Head and Senior Consultant of Surgical Intensive Care, SGH.

While antibody titres against SARS-CoV-2 wane with time, the immune system is capable of producing memory B-cells that can last for at least 6 months after infection, suggesting that the body will be able to protect itself in the case of re-exposure, according to a new study.

Spending too much time sitting cannot be good for the body, and rising to one's feet breaks up such a behaviour and yields small, but meaningful, reductions in certain cardiovascular disease (CVD) risk factors, according to the results of a meta-analysis.

Being barefoot best bet for patients with knee osteoarthritis

01 Jan 2021

Patients with knee osteoarthritis may do well to spend more time in bare feet than wearing footwear and performing moderate physical activity (PA), as the latter may increase instead of lower the risk of pain flares, a study reports.

The study included 120 patients (mean age, 59.9 years; 90 percent female; mean body mass index, 28.0 kg/m2) who had previous episodes of pain flares. All patients were assessed every 10 days for up to 3 months. The majority (84.6 percent) of the population resided in urban areas, and about half (40.9 percent) had no permanent employment.

The mean number of flares per person was 1.91. The patients reported being barefoot for a mean of 12.7 hours and wore footwear an average of 5.1 hours daily. Nearly all (99 percent) wore footwear with a heel height of <2.5 cm.

Conditional logistic regression analysis revealed that longer duration of being barefoot, 1 and 2 days prior, lowered the odds of having pain flares by 15 percent (odds ratio [OR], 0.85, 95 percent confidence interval [CI], 0.80–0.90).

In contrast, moderate PA performed 1 or 2 days prior was associated with a significantly elevated risk of pain flares (OR, 4.29, 95 percent CI, 2.52–7.30 and OR, 3.36, 95 percent CI, 2.01–5.61, respectively). Similarly, prolonged use of footwear at 1 and 2 days prior conferred a risk increase (OR, 1.15, 95 percent CI, 1.07–1.23 and OR, 1.10, 95 percent CI, 1.03–1.18, respectively).

The findings provide evidence that being barefoot is associated with lower mechanical loads on the knee and can prevent the occurrence of pain flares.
