Abstract Objectives Fructose providing excess calories has been shown to increase postprandial triglycerides (TAG). Whether this effect holds for different food sources of fructose-containing sugars is unclear. We conducted a systematic review and meta-analysis of controlled feeding trials on the effect of different food sources of fructose-containing sugars at different levels of energy control on postprandial blood lipids (NCT02716870). Methods MEDLINE, EMBASE, and Cochrane Library were searched through June 1st, 2020 for controlled feeding trials ≥7-days assessing the effect of food sources of fructose-containing sugars on postprandial lipids. Trial designs were prespecified based on energy control: substitution (energy matched replacement of sugars by other macronutrients); addition (excess energy from sugars added to diets); subtraction (energy from sugars subtracted from diets); and ad libitum (energy from sugars freely replaced by other macronutrients) trials. Independent reviewers extracted data and assessed risk of bias. Outcomes were postprandial TAG and apoB48. Certainty of evidence was assessed using GRADE. Results We included 29 trials (60 trial comparisons, N = 943) assessing 5 food sources (SSBs, fruit, sweets and desserts, added caloric sweetener and mixed sources) across 4 levels of energy control. Total fructose-containing sugars increased postprandial TAG in substitution (MD: 0.17 mmol/L [95% CI: 0.05, 0.30], P = 0.007), addition (0.38 mmol/L [0.13, 0.62], P = 0.003), and ad libitum (0.17 mmol/L [0.02, 0.31], P = 0.024) trials and increased apoB48 in addition trials (0.12 g/L [0.07, 0.18], P < 0.001).There was evidence of interaction by food source with SSBs increasing postprandial TAG and apoB48 in addition trials and mixed sources increasing postprandial TAG in ad libitum trials. The certainty of the evidence was “moderate” for SSBs increasing TAG in addition trials and mixed sources increasing TAG in ad libitum trials and “low” for all other comparisons. Conclusions Food source more than energy control appears to mediate fructose-containing sugars on postprandial lipids. Good evidence suggests that SSBs and mixed sources increase postprandial lipids while evidence is less certain for the lack of effect of other food sources. More high-quality trials of different food sources are needed. Funding Sources Primary: Diabetes Canada.

Abstract Objectives Sugar-sweetened beverages (SSBs) have been linked to weight gain, and it is unclear if other food sources of fructose-containing sugars behave similarily. We conducted a systematic review and meta-analysis of controlled feeding trials to assess the effect of different food sources of fructose-containing sugars on body weight. Methods MEDLINE, EMBASE, and The Cochrane library were searched through January 2019. We included controlled feeding trials of ≥2 weeks investigating the effect of different food sources of sugars. Four levels of energy control were prespecified: substitution (energy-matched comparisons); addition (energy from sugars added to diet); subtraction (energy from sugars subtracted from diet); or ad libitum (energy from sugars freely replaced). The primary outcome was body weight. Two independent reviewers extracted data and assessed risk of bias. Data were pooled using random effects models and expressed as mean differences (MDs) with 95% confidence intervals (CIs). GRADE assessed the certainty of evidence. Results We identified 110 controlled trials (N = 5133) assessing the effect of 7 different food sources of fructose-containing sugars (SSBs, fruit, fruit juice, dried fruit; baked goods, sweets, & desserts; mixed sources; added caloric sweeteners). No effect on body weight was observed in substitution trials, whereas there was an increasing effect in addition trials (MD, 0.23 kg [95% CI, 0.06 to 0.40]) and ad libitum trials (1.43 kg [0.78 to 2.16]), and a decreasing effect in subtraction trials (–0.52 kg [–1.02 to −0.02]). There was evidence of interaction by food source with fruit showing weight loss in substitution trials and SSBs showing weight gain in addition trials. The certainty of evidence was moderate for the effects in the addition and subtraction trials and high for the effects in the substitution and ad libitum trials. Conclusions Energy control and food source appear to mediate the effect of fructose-containing sugars on body weight. Food sources of fructose-containing sugars adding excess energy to diets (especially sugars-sweetened beverages) appear to lead to weight gain. There is low to moderate likelihood that more research will substantially alter our estimates (ClinicalTrials.gov Identifier, NCT02558920) Funding Sources American Society for Nutrition Foundation (commissioned and funded), Diabetes Canada.

Abstract Objectives Sugar-sweetened beverages (SSBs) have been linked to weight gain. It is unclear if other food sources of fructose-containing sugars behave similarly. We conducted a systematic review and meta-analysis of controlled feeding trials to assess the effect of different food sources of fructose-containing sugars on body weight and markers of adiposity. Methods MEDLINE, Embase, and the Cochrane Library were searched through January 2020 for controlled feeding trials ≥2 weeks on the effect of fructose-containing sugars. Trial designs were prespecified by energy control: substitution (energy matched replacement of sugars in diets); addition (excess energy from sugars added to diets); subtraction (energy from sugars subtracted from diets); and ad libitum (energy from sugars freely replaced in diets). The primary outcome was body weight. Secondary outcomes were body mass index, body fat and waist circumference. Independent reviewers extracted data and assessed risk of bias. Certainty of evidence was assessed using GRADE. (NCT02558920) Results We identified 119 controlled trials (368 trial comparisons, N = 5263) assessing the effect of 10 food sources (SSBs, sweetened dairy alternative (soy), fruit juice, fruit drink, fruit, dried fruit, sweetened cereal grains/bars, sweets, added sweeteners and mixed sources). Total fructose-containing sugars increased body weight (mean difference, 0.29 kg [95% confidence interval, 0.05 to 0.53 kg], P = 0.017) and body fat in addition trials with no effect in other analyses or outcomes. There was evidence of interaction by food source in substitution trials with fruit reducing and mixed sources increasing some outcomes and in addition trials with 100% fruit juice reducing and SSBs and mixed sources increasing some outcomes. The overall certainty of evidence was moderate for the decreasing effect of fruit and fruit juice and the increasing effect of SSBs and mixed sources and high-to-very low for other comparisons. Conclusions Energy control and food source may mediate the effect of fructose-containing sugars on adiposity. The evidence provides good indication that fruit and 100% fruit juice decrease and SSBs and mixed sources increase markers of adiposity. More high-quality randomized trials of different foods are needed to improve our estimates. Funding Sources American Society for Nutrition, Diabetes Canada, CIHR, Mitacs.

Abstract Objectives Excess calories as fructose may initiate pathways increasing biomarkers of inflammation. Whether this effect is mediated by the food matrix at different energy levels is unknown. We conducted a systematic review and meta-analysis of controlled feeding trials of the effect of food sources of fructose-containing sugars at different energy control levels on biomarkers of inflammation (NCT02716870). Methods We searched MEDLINE, Embase, and the Cochrane Library through January 15 2020 for controlled trials ≥7d. Trial designs were prespecified based on energy control: substitution (energy-matched replacement of sugar in the diet); addition (excess energy from sugar added to diets); subtraction (energy from sugar subtracted from diets); ad libitum (energy from sugar freely replaced in the diet). The primary outcome was C-reactive protein (CRP). Secondary outcomes were tumor necrosis factor-alpha (TNF-α) and interleukin 6 (IL-6). Independent reviewers extracted data and assessed the risk of bias. Certainty of evidence was assessed by GRADE. Results We included 48 trials (109 trial comparisons, n = 2108) assessing the effect of 10 food sources (SSBs, sweetened dairy, sweetened dairy alternatives (soy), fruit, 100% fruit juice, dried fruit, sweetened cereal grains/bars, sweets, added nutritive sweetener, and mixed sources) across the 4 levels of energy control. Total fructose-containing sugars had no effect on any outcome in any level of energy control. There was evidence of interaction by food source; in substitution trials, sweetened dairy alternative (soy) decreased CRP. In addition trials, fruit decreased while added nutritive sweetener increased TNF-α. The certainty of evidence was low for the effect of sweetened dairy alternative (soy) on CRP in substitution trials, and generally moderate for all other comparisons. Conclusions Food source more than energy control appears to mediate the effect of fructose-containing sugars on inflammation. The evidence provides some indication that sweetened dairy alternatives (soy) and fruit decrease and added nutritive sweeteners increase biomarkers of inflammation. More high-quality randomized trials of different fructose containing food sources are needed to improve our estimates. Funding Sources Diabetes Canada.

Abstract Objectives Overconsumption of fructose-containing sugars may increase blood pressure. Whether this effect is mediated by the food matrix is unclear. We conducted a systematic review and meta-analysis of controlled feeding trials of the effect of food sources of fructose-containing sugars at different levels of energy control on blood pressure (NCT02716870). Methods We searched MEDLINE, Embase and the Cochrane Library through January, 2020 for controlled trials ≥7d. Trial designs were prespecified based on energy control: substitution (energy matched replacement of sugars in the diet); addition (excess energy from sugars added to diets); subtraction (energy from sugars subtracted from diets); and ad libitum (energy from sugars freely replaced in the diet) trials. Outcomes were systolic blood pressure (SBP) and diastolic blood pressure (DBP). Independent reviewers extracted data and assessed risk of bias. Certainty of evidence was assessed by GRADE. Results We included 76 trials (121 trial comparisons, N = 4 302) assessing 9 food sources (sugar-sweetened beverages [SSBs], sweetened dairy alternatives, 100% fruit juice, fruit, dried fruit, sweets, added nutritive sweetener, sweetened cereal grains/bars, and mixed sources) across the 4 levels of energy control. Total fructose-containing sugars decreased SBP (mean difference, −2.76 mmHg [95% CI, −4.36, −1.16], P = 0.001) and DBP (−1.26 mmHg [−2.29, −0.23], P = 0.016) in addition trials and the removal of these sugars decreased SBP (−1.79 mmHg [−3.36, −0.21], P = 0.026) in subtraction trials. There was evidence of interaction by food source with fruit decreasing and sweets and mixed sources increasing SBP and DBP in addition trials and the removal of SSBs decreased SBP in subtraction trials. The certainty of evidence was generally moderate to low for all food source-outcome relationships, except for the decreasing-effect of fruit on DBP in addition trials (high). Conclusions Food source and energy control appear to mediate the effect of fructose-containing sugars on blood pressure. The evidence provides a good indication that fruit decreases while excess calories from SSBs, sweets and mixed sources increase blood pressure. More high-quality trials of different food sources are needed to improve our estimates. Funding Sources Diabetes Canada.

Abstract Objectives Fructose as a source of excess calories increases non-alcoholic fatty liver disease (NAFLD) markers. Whether this effect is mediated by the food matrix is unknown. We thus conducted a systematic review and meta-analysis of controlled feeding trials assessing the effect of important food sources of fructose-containing sugars at different energy control levels on NAFLD markers. Methods MEDLINE, Embase, and Cochrane Library were searched through January 18, 2021 for controlled trials ≥7-days. Four trial designs were prespecified based on energy control: substitution (energy-matched replacement of sugars by other macronutrients); addition (excess energy from sugars added to diets); subtraction (energy from sugars subtracted from diets); and ad libitum (energy from sugars freely replaced by other macronutrients). The primary outcome was intrahepatocellular lipid (IHCL). Secondary outcomes were alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Independent reviewers extracted data and assessed risk of bias. Certainty of evidence was assessed by GRADE. Results We included 44 trials (65 trial comparisons, n = 1941) assessing the effect of 8 food sources (sugar-sweetened beverages [SSBs]; sweetened dairy alternative [soy]; fruit juice; fruit; dried fruit; baked goods, desserts and sweets; added nutritive sweetener; and mixed sources) across 4 energy levels. Total fructose-containing sugars increased IHCL in addition trials (standardized mean difference = 1.69 [95% CI, 1.00–2.37], P < 0.001), but no effect in substitution, subtraction and ad libitum trials. There was evidence of interaction by food source in addition trials with SSBs increasing IHCL and ALT, and mixed sources increasing AST. The overall certainty of evidence was high for SSBs on IHCL and ALT in addition trials and high to very low for all other comparisons. Conclusions Energy control and food source appear to mediate the effect of fructose-containing sugars on NAFLD markers. High certainty evidence suggests that SSBs providing excess energy increase NAFLD markers, while the evidence is less certain that mixed sources share the same effect and other food sources do not. More high-quality randomized trials of different food sources are needed to improve our estimates (ClinicalTrials.gov identifier, NCT02716870). Funding Sources Primary funding: Diabetes Canada.

Abstract Objectives Fructose as a source of excess calories increases uric acid. Whether this effect is mediated by the food matrix at different levels of energy is unknown. We aim to conduct a systematic review and meta-analysis of controlled feeding trials on the effect of food sources of fructose-containing sugars at different energy levels on uric acid (NCT02716870). Methods MEDLINE, Embase and the Cochrane Library were searched through January 27, 2020 for controlled trials ≥7-days assessing the effect of food sources of fructose-containing sugars on uric acid. Trial designs were prespecified based on energy control: substitution (energy matched replacement of sugars by other macronutrients); addition (excess energy from sugars added to diets); subtraction (energy from sugars subtracted from diets); and ad libitum (energy from sugars freely replaced by other macronutrients) trials. Independent reviewers extracted data and assessed risk of bias. Certainty of evidence was assessed using the GRADE approach. Results Eligibility was met by 41 trials (72 trial comparisons, N = 2109) assessing the effect of 9 food sources (sugar-sweetened beverages [SSBs], sweetened dairy, fruit drink [lemonade], 100% fruit juice, fruit, dried fruit [raisins], baked goods desserts and sweets, added nutritive [caloric] sweetener and mixed sources) across the 4 energy levels. Total fructose-containing sugars increased uric acid in substitution trials (mean difference, 0.15 mg/dL [95% confidence interval, 0.03 to 0.27 mg/dL], P = 0.012) with no effect in addition, subtraction or ad libitum trials. There was evidence of interaction by food source with SSBs and baked goods, desserts and sweets increasing uric acid in substitution and SSBs increasing and 100% fruit juice decreasing uric acid in addition trials. The overall certainty of evidence was moderate for the increasing effect of SSBs in substitution and addition trials and low to very low for all other comparisons. Conclusions Food source more than energy control mediate the effect of fructose-containing sugars on uric acid. SSBs and baked goods, desserts and sweets appear to increase, and 100% fruit juice appear to decrease uric acid. More high-quality trials of different food sources of fructose-containing sugars are needed to improve our estimates. Funding Sources Diabetes Canada.

ObjectiveSugar-sweetened beverages (SSBs) are associated with hyperuricaemia and gout. Whether other important food sources of fructose-containing sugars share this association is unclear.DesignTo assess the relation of important food sources of fructose-containing sugars with incident gout and hyperuricaemia, we conducted a systematic review and meta-analysis of prospective cohort studies.MethodsWe searched MEDLINE, Embase and the Cochrane Library (through 13 September 2017). We included prospective cohort studies that investigated the relationship between food sources of sugar and incident gout or hyperuricaemia. Two independent reviewers extracted relevant data and assessed the risk of bias. We pooled natural-log transformed risk ratios (RRs) using the generic inverse variance method with random effects model and expressed as RR with 95% confidence intervals (CIs). The overall certainty of the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation system.ResultsWe identified three studies (1 54 289 participants, 1761 cases of gout), comparing the highest with the lowest level of exposure for SSBs, fruit juices and fruits. No reports were found reporting incident hyperuricaemia. Fruit juice and SSB intake showed an adverse association (fruit juice: RR=1.77, 95% CI 1.20 to 2.61; SSB: RR=2.08, 95% CI 1.40 to 3.08), when comparing the highest to lowest intake of the most adjusted models. There was no significant association between fruit intake and gout (RR 0.85, 95% CI 0.63 to 1.14). The strongest evidence was for the adverse association with SSB intake (moderate certainty), and the weakest evidence was for the adverse association with fruit juice intake (very low certainty) and lack of association with fruit intake (very low certainty).ConclusionThere is an adverse association of SSB and fruit juice intake with incident gout, which does not appear to extend to fruit intake. Further research is needed to improve our estimates.Trial registration numberNCT02702375; Results.

Abstract This systematic review compared the oral health status between institutionalized and non-institutionalized elders. The following electronic databases were searched: PubMed (Medline), Scopus, Web of Science, Lilacs and Cochrane Library, in a comprehensive and unrestricted manner. Electronic searches retrieved 1687 articles, which were analyzed with regards to respective eligibility criteria. After reading titles and abstracts, five studies were included and analyzed with respect their methodological quality. Oral status of institutionalized and non-institutionalized elderly was compared through meta-analysis. Included articles involved a cross-sectional design, which investigated 1936 individuals aged 60 years and over, being 999 Institutionalized and 937 non-institutionalized elders. Studies have investigated the prevalence of edentulous individuals, the dental caries experience and the periodontal status. Meta-analysis revealed that institutionalized elderly have greater prevalence of edentulous (OR = 2.28, 95%CI = 1.68-3.07) and higher number of decayed teeth (MD = 0.88, 95%CI = 0.71-1.05) and missed teeth (MD = 4.58, 95%CI = 1.89-7.27). Poor periodontal status did not differ significantly between groups. Compared to non-institutionalized, institutionalized elders have worse dental caries experience.

Peripartum Depression

Abstract Background Peripartum depression is a common disorder with very high potential hazards for both the patients and their babies. The typical treatment options include antidepressants and electroconvulsive therapy. However, these treatments do not ensure the safety of the fetus. Recently, repetitive transcranial magnetic stimulation has emerged as a promising treatment for neuropathies as well as depression. Nevertheless, many studies excluded pregnant women. This systematic review was conducted to confirm whether repetitive transcranial magnetic stimulation was a suitable treatment option for peripartum depression. Methods We performed a systematic review that followed the PRISMA guidelines. We searched for studies in the MEDLINE, PsycINFO, EMBASE, and Cochrane library databases published until the end of September 2020. Eleven studies were selected for the systematic review, and five studies were selected for quantitative synthesis. Data analysis was conducted using Comprehensive Meta-Analysis 3 software. The effect size was analyzed using the standardized mean difference, and the 95% confidence interval (CI) was determined by the generic inverse variance estimation method. Results The therapeutic effect size of repetitive transcranial magnetic stimulation for peripartum depression was 1.394 (95% CI: 0.944–1.843), and the sensitivity analysis effect size was 1.074 (95% CI: 0.689–1.459), indicating a significant effect. The side effect size of repetitive transcranial magnetic stimulation for peripartum depression was 0.346 (95% CI: 0.214–0.506), a meaningful result. There were no severe side effects to the mothers or fetuses. Conclusions From various perspectives, repetitive transcranial magnetic stimulation can be considered an alternative treatment to treat peripartum depression to avoid exposure of fetuses to drugs and the severe side effects of electroconvulsive therapy. Further research is required to increase confidence in the results.

Abstract Obesity has been shown to intensify the decline of physical function and lead to frailty. Nutrition is an important method in managing obesity and frailty, while seldom reviews have ever explored the effects of nutritional education interventions. We conducted a systematic review (PROSPERO: CRD42019142403) to explore the effectiveness of nutritional education interventions in managing body composition and physio-psychosocial parameters related to frailty. Randomized controlled trials and quasi-experimental studies were searched in CINAHL, Cochrane Library, EMBASE, MEDLINE, PsycINFO, PubMed and Scopus from 2001 to 2019. Hand search for the reference lists of included papers was conducted as well. We assessed the quality of included studies by Cochrane risk of bias tool. Meta-analyses and narrative synthesis were used to analyse the data. Two studies with low risk of bias were screened from 180 articles, which involved 177 older people with an average age of 69.69±4.08 years old. The results showed that nutritional education was significantly effective in reducing body weight and fat mass than exercises, and it was beneficial to enhancing physical function and psychosocial well-being. But the effects of nutritional education in increasing muscle strength were not better than exercises. The combined effects of nutritional education and exercises were superior than either exercises or nutritional education interventions solely in preventing the loss of lean mass and bone marrow density, and in improving physical function. Due to limited numbers of relevant studies, the strong evidence of effectiveness of nutritional education interventions on reversing frailty is still lacking.
