Relation of preconception eating behaviours to dietary pattern trajectories and gestational weight gain from preconception to late pregnancy.

Studies examining preconception eating behaviours with longitudinal dietary patterns from preconception to late pregnancy as well as gestational weight gain (GWG) are limited. We derived dietary pattern trajectories from preconception to late-pregnancy, and related preconception eating behaviours to these trajectories and GWG. Preconception eating behaviours were assessed using the Three-Factor Eating Questionnaire measuring cognitive restraint (CR) - conscious restriction of food intake, emotional eating (EE) - overeating in response to negative emotions, and uncontrolled eating (UE) - overeating with a feeling of lack of control. Dietary intakes were measured at preconception, 20-21 and 34-36 weeks' gestation with food frequency questionnaires. Dietary patterns were determined using factor analysis, and trajectories derived using group-based trajectory modelling. Inadequate and excessive GWG were defined according to Institute of Medicine guidelines based on weights at preconception and the last antenatal visit (median: 38 weeks' gestation). Two dietary patterns were derived: 'Fast Food, Fried Snacks and Desserts (FFD)' and 'Soup, Fish and Vegetables (SFV)'. Adherence trajectories from preconception to late-pregnancy were characterised as consistently high ("stable-high") and low ("stable-low"). Women with higher UE scores had higher odds of being in the "stable-high" trajectory (n = 34) of the FFD pattern [Odds Ratio (OR): 1.25, 95% Confidence Interval (CI): 1.03, 1.51], compared to "stable-low" (n = 260). Percentages of women with inadequate, adequate or excessive GWG were 21.7% (n = 70), 25.8% (n = 83), and 52.5% (n = 169), respectively; women with higher EE scores had a higher likelihood of excessive GWG [Relative Risk Ratio (RRR): 1.35, 95% CI: 1.02, 1.80], but this association was attenuated after adjusting for preconception body mass index. Eating behaviour interventions to improve dietary patterns among pregnant women may need to start as early as preconception, incorporating strategies to manage UE.

Evaluation of paper-based and web-based food frequency questionnaires for 7-year-old children in Singapore.

Advances in technology enabled the development of a web-based, pictorial FFQ to collect parent-report dietary intakes of 7-year-old children in the Growing Up in Singapore Towards healthy Outcomes study. This study aimed to compare intakes estimated from a paper-FFQ and a web-FFQ and examine the relative validity of both FFQ against 3-d diet records (3DDR). Ninety-two mothers reported food intakes of their 7-year-old child on a paper-FFQ, a web-FFQ and a 3DDR. A usability questionnaire collected participants' feedback on the web-FFQ. Correlations and agreement in energy, nutrients and food groups intakes between the dietary assessments were evaluated using Pearson's correlation, Lin's concordance, Bland-Altman plots, Cohen's κ and tertile classification. The paper- and web-FFQ had good correlations (≥ 0·50) and acceptable-good agreement (Lin's concordance ≥ 0·30; Cohen's κ ≥ 0·41; ≥ 50 % correct and ≤ 10 % misclassification into same or extreme tertiles). Compared with 3DDR, both FFQ showed poor agreement (< 0·30) in assessing absolute intakes except micronutrients (web-FFQ had acceptable-good agreement), but showed acceptable-good ability to classify children into tertiles (κ ≥ 0·21; ≥ 40 % and ≤ 15 % correct or misclassification). Bland-Altman plots suggest good agreement between web-FFQ and 3DDR in assessing micronutrients and several food groups. The web-FFQ was well-received, and majority (81 %) preferred the web-FFQ over the paper-FFQ. The newly developed web-FFQ produced intake estimates comparable to the paper-FFQ, has acceptable-good agreement with 3DDR in assessing absolute micronutrients intakes and has acceptable-good ability to classify children according to categories of intakes. The positive acceptance of the web-FFQ makes it a feasible tool for future dietary data collection.

Tracking of Maternal Diet from Pregnancy to Postpregnancy: A Systematic Review of Observational Studies.

We systematically reviewed studies to examine changes in women's diets from pregnancy to the postpregnancy period and sought to understand the characteristics of women making these changes. From a search of 4 databases and up to November 2019, 17 studies met our inclusion criteria. They reported changes in various dietary aspects. Mixed findings were reported for changes in energy and micronutrient intakes. Most studies reported significant decreases in fruit and vegetable consumption, diet quality, and adherence to a healthier dietary pattern during the transition from pregnancy to postpregnancy, whereas increases in discretionary food and fat intakes were observed. Women with lower education level, lower income, and/or who worked full-time tended to have poorer dietary behaviors postpregnancy. Further research, with better aligned dietary measurement time points during pregnancy and postpartum and standardization of dietary assessment tools, is needed for future studies to be comparable. The systematic review protocol was registered in the PROSPERO International Prospective Register of Systematic Reviews as CRD42020158033.

Effect of phacoemulsification cataract surgery on intraocular pressure in early glaucoma: A prospective multi-site study.

IMPORTANCE: Cataract and primary open-angle glaucoma (POAG) commonly co-exist, and cataract surgery is thought to reduce intraocular pressure (IOP), the major modifiable risk factor of POAG. BACKGROUND: Previous studies exploring the effect of cataract surgery on IOP are limited by retrospective design, lack of a control group, medication use and washout and loss to follow up. DESIGN: Prospective, multicentre, matched case-control Australian study. PARTICIPANTS: 171 eyes of 108 POAG patients who underwent cataract surgery, matched to 171 control eyes. METHODS: Serial longitudinal IOP measurements were compared before and after cataract surgery, and relative to the controls. A mixed-effect model was used for the longitudinal data. MAIN OUTCOME MEASURES: Change in IOP. RESULTS: The mean follow-up time was 4.8 (1.4) years. Cataract surgery reduced mean IOP by 2.22 mmHg (95% confidence interval: 1.93-2.52 mmHg, P < .001) with 59 eyes (34%) achieving at least 3 mmHg reduction. Compared to matched controls, the mean reduction in IOP was 1.75 mmHg (95% confidence interval 1.15-2.33 mmHg; P < .001). Higher preoperative IOP and being on fewer topical glaucoma medications preoperatively were strongly predictive of a larger IOP reduction in a multivariable model. Anterior chamber depth was not associated with IOP reduction. Eyes with preoperative IOP ≥24 mmHg had a mean IOP reduction of 4.03 mmHg with 81% experiencing at least 3 mmHg reduction. Sub-analysis of medication naïve and pseudoexfoliation patients showed similar results. CONCLUSIONS AND RELEVANCE: Cataract surgery has a confirmed effect in reducing IOP in a "real world" setting of early glaucoma patients.

Long-term Clinical and Cost Outcomes of a Pharmacist-managed Risk Factor Management Clinic in Singapore: An Observational Study.

PURPOSE: Few studies have determined the benefits of pharmacist-run clinics within a tertiary institution, and specifically on their capability to improve clinical outcomes as well as reduce the cost of illness. This study was designed to investigate the effectiveness of a pharmacist-managed risk factor management clinic (RFMP) in an acute care setting through the comparison of clinical (improvement in glycosylated hemoglobin level) and cost outcomes with patients receiving usual care. METHODS: This single-center, observational study included patients aged ≥21 years old and diagnosed with type 2 diabetes mellitus (DM) who received care within the cardiology department of a tertiary institution between January 1, 2014, and December 31, 2015. The intervention group comprised patients who attended the RFMP for 3 to 6 months, and the usual-care group comprised patients who received standard cardiologist care. Univariate analysis and multiple linear regression were conducted to analyze the clinical and cost outcomes. FINDINGS: A total of 142 patients with DM (71 patients in the intervention group and 71 patients in the usual-care group) with similar baseline characteristics were included. After adjusting for differences in baseline systolic blood pressure and triglyceride levels, the mean reduction in glycosylated hemoglobin level at 6 months from baseline in the intervention group was significantly lower by 0.78% compared with the usual-care group. Patients in the usual-care group had a significantly higher risk of hospital admissions within the 12 months from baseline compared with the intervention group (odds ratio, 3.84 [95% CI, 1.17-12.57]; P = 0.026). Significantly lower mean annual direct medical costs were also observed in the intervention group (US $8667.03 [$17,416.20] vs US $56,665.02 [$127,250.10]; P = 0.001). IMPLICATIONS: The pharmacist-managed RFMP exhibited improved clinical outcomes and reduced health care costs compared with usual care within a tertiary institute.

Drug-Coated Balloons: A Safe and Effective Alternative to Drug-Eluting Stents in Small Vessel Coronary Artery Disease.

BACKGROUND: Drug-coated balloons (DCB) have been used to treat de novo small vessel coronary disease (SVD), with promising results and shorter dual antiplatelet therapy (DAPT) duration compared to drug-eluting stents (DES). We compared safety and effectiveness of the two treatments at 1 year. METHODS: We reviewed 3,613 angioplasty cases retrospectively from 2011 to 2013 and identified 335 patients with SVD treated with device diameter of ≤2.5 mm. DCB-only angioplasty was performed in 172 patients, whereas 163 patients were treated with second-generation DES. RESULTS: DCB patients had smaller reference vessel diameter (2.22 ± 0.30 vs. 2.44 ± 0.19 mm, P < 0.001) and received smaller devices (median diameter 2.25 vs. 2.50 mm, P < 0.001) compared to the DES group. DES-treated vessels had larger acute lumen gain (1.71 ± 0.48 mm) than DCB (1.00 ± 0.53 mm, P < 0.001). Half the patients had diabetes mellitus. While there were more patients presenting with acute coronary syndrome (ACS) in the DCB group (77.9% vs. 62.2%, P = 0.013), they received shorter DAPT (7.4 ± 4.7 vs. 11.8 ± 1.4 months, P < 0.001) than the DES group. The 1-year composite major adverse cardiac event rate was 11.6% in the DCB arm and 11.7% in the DES arm (P = 1.000), with target lesion revascularization rate of 5.2% and 3.7%, respectively, (P = 0.601). CONCLUSIONS: In this high-risk cohort of patients, DCB-only angioplasty delivered good clinical outcome at 1 year. The results were comparable with DES-treated patients, but had the added benefit of a shorter DAPT regime.

Drug coated balloon angioplasty in elderly patients with small vessel coronary disease.

BACKGROUND: Coronary angioplasty in advanced age is associated with higher rate of comorbidities and complications. Drug coated balloon only angioplasty (DCBA) has emerged as an alternative to treat small vessel coronary disease (SVCD), of reference vessel diameters <2.8 mm, with shorter duration of dual antiplatelet (DAPT). This is the first study to assess the DCBA efficacy in an elderly population with SVCD. METHODS AND RESULTS: We performed a prospective study of 447 patients (334 patients aged <75 and 113 patients aged ⩾75 years old) acquired from the SeQuent Please Small Vessel 'Paclitaxel-Coated Balloon Only' registry. In the older age group, more patients have hypertension (89% versus 77%; p = 0.006), renal insufficiency (21% versus 6%; p < 0.001), atrial fibrillation (17% versus 7%; p = 0.001), and calcified lesions (33% versus 20%; p = 0.006). At 30 days, there was one myocardial infarction requiring target lesion revascularization (TLR) in the younger group. No major adverse cardiac event (MACE) was observed in the older group. At 9 months, the MACE rate in the younger group was 4.2% and 6.1% in the older group (p = 0.453), with TLR rates at 3.9% and 3.0% (p = 0.704) respectively. There was no cardiac death observed. CONCLUSION: DBCA in the elderly with SVCD is as safe and effective compared with younger patients despite more complex anatomy and comorbidities.
