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.

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.

Use of thyroid hormone therapy does not seem to protect older adults with subclinical hypothyroidism against mortality, but it appears to confer survival benefits to those aged <65 years, results of a study have shown.

Which diet causes periodontitis?

20 Dec 2020

Most dietary patterns do not contribute to periodontitis extent, but one rich in salad, fruit, and vegetables and with plain water or tea to drink is associated with lower clinical attachment loss (CAL) extent, suggests a recent study.

The authors used two 24-hour dietary recalls and periodontal examination data from the cross-sectional US NHANES (2009–2014; n=10,010) to examine potential associations between diet and periodontitis. They extracted dietary patterns using treelet transformation, a data-driven hierarchical clustering and dimension reduction technique.

Robust logistic quantile regression, adjusting for age, sex, ethnicity, education level, smoking, body mass index, and diabetes, was used to estimate associations between each pattern (treelet component [TC]) and extent of periodontitis (proportion of site with CAL ≥3 mm).

Eight TCs explained 21 percent of variation in diet, of which one (TC1) correlated with CAL extent. High TC1 scores were characterized by a diet rich in salad, fruit, vegetables, poultry and seafood, and plain water or tea to drink.

A substantial negative gradient was noted in CAL extent from the lowest to the highest decile of TC1 (median proportion of sites with CAL ≥3 mm: decile 1, 19.1 percent; decile 10, 8.1 percent; decile 10 vs decile 1 odds ratio, 0.67, 95 percent confidence interval, 0.46–0.99).

“Treelet transformation may be a useful approach for calculating dietary patterns in nutrition research,” the authors said.

Periodontitis is a major cause of tooth loss globally and is associated with age, smoking, and diabetes.
