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.

Very-low-energy diet helps obese women get pregnant faster

23 Nov 2020

A very-low-energy diet (VLED) programme yields substantial weight loss in women with obesity and leads to faster conception compared with a standard dietary intervention (SDI), according to a study.

The analysis included 164 normoglycaemic women (mean age, 32 years) with body mass index 30–55 kg/m2 who were planning pregnancy. They were randomly assigned to a 12-week SDI (n=79) or modified VLED (n=85). Those who completed the intervention were followed for up to 48 weeks to record the time of pregnancy.

Women in the SDI group were instructed to eat an energy-reduced diet, specifically a diet containing 500 calories less than their current intake, and with a macronutrient composition consistent with the Australian Guide to Healthy Eating. On the other hand, those in the VLED group were instructed to eat two daily meals of a VLED formulation and a third meal consisting of two cups of low-starch vegetables, 150 g lean meat, and two teaspoons of oil. All women were asked to log >10,000 steps per day on their pedometer.

At the end of the intervention, the VLED group lost significantly more weight than the SDI group (–11.9 percent vs –3.1 percent; p<0.01). Weight regain between week 12 and either pregnancy or week 60 was comparable between the two groups (3.2 percent vs 2.9 percent, respectively; p=0.30).

Among the women who completed the 12-week intervention, time to pregnancy was significantly shorter in the VLED group than in the SDI group (median, 51.0 days vs 140.5 days; p=0.03). The pregnancy rate was also significantly higher in the VLED group (59 percent vs 41 percent; p=0.03).

The present data may have important implications for women with obesity who are planning pregnancy.
