Vegan diets, where animal- and all their by-products are excluded from the diet, have gained popularity, especially in the last decade. However, the evaluation of this type of diet has not been well ...addressed in the scientific literature. This study aimed to investigate the adequacy of vegan diets in European populations and of their macro- and micronutrient intakes compared to World Health Organization recommendations.
A systematic search in PubMed, Web of Science, IBSS, Cochrane library and Google Scholar was conducted and 48 studies (12 cohorts and 36 cross-sectional) were included.
Regarding macronutrients, vegan diets are lower in protein intake compared with all other diet types. Veganism is also associated with low intake of vitamins B2, Niacin (B3), B12, D, iodine, zinc, calcium, potassium, selenium. Vitamin B12 intake among vegans is significantly lower (0.24–0.49 μg, recommendations are 2.4 μg) and calcium intake in the majority of vegans was below recommendations (750 mg/d). No significant differences in fat intake were observed. Vegan diets are not related to deficiencies in vitamins A, B1, Β6, C, E, iron, phosphorus, magnesium, copper and folate and have a low glycemic load.
Following a vegan diet may result in deficiencies in micronutrients (vitamin B12, zinc, calcium and selenium) which should not be disregarded. However, low micro- and macronutrient intakes are not always associated with health impairments. Individuals who consume a vegan diet should be aware of the risk of potential dietary deficiencies.
Substance use during pregnancy is a major health issue for both the mother and the fetus, but it also represents an important public health concern.
The aim of this review was to summarize and ...compare recommendations from recently published guidelines on substance use during pregnancy and especially regarding alcohol, smoking, and drug use.
A descriptive review of guidelines from the Royal Australian and New Zealand College of Obstetricians and Gynaecologists, the World Health Organization (WHO), the Society of Obstetricians and Gynaecologists of Canada, and the American College of Obstetricians and Gynecologists on substance use was conducted. Regarding the term "substance use," the most recently published
substances were used.
All the reviewed guidelines recommend appropriate counseling and screening women regarding alcohol, smoking, and drug use during the antenatal period, while the management options vary. More specifically, the prompt management of alcohol dependence is emphasized by all the guidelines except from the Royal Australian and New Zealand College of Obstetricians and Gynaecologists, which makes no recommendation upon. The use of alcohol during breastfeeding should be avoided. Regarding smoking cessation, all guidelines recommend the use of certain psychosocial, behavioral interventions, and pharmacotherapy. All the guidelines, except the one from the WHO, suggest screening drug users for coexistent sexually transmitted infections. Brief interventions are considered beneficial, while a gradual decrease in benzodiazepines is suggested, as well as the discontinuation of marijuana and methamphetamine use. However, there is controversy regarding breastfeeding in those women as the WHO recommends in favor, whereas the Society of Obstetricians and Gynaecologists of Canada and the American College of Obstetricians and Gynecologists recommend against this practice. Finally, all the guidelines state that, following delivery, close monitoring of the neonate is needed.
The diversity of guidelines' recommendations concerning substance use reflects the different ways of the management of pregnant women during routine antenatal care due to absence of strong evidence. More research in the areas of dispute may allow the adoption of an international consensus, in order to early detect and appropriately manage pregnant women with harmful addictions.
The aim of this study was to develop and evaluate the validity of a short, culture-specific, semiquantitative food frequency questionnaire (FFQ) for Greek dietary habits and among a population of ...pregnant women, and to assess the adherence of reported nutritional habits to the Mediterranean diet.
The validity of the FFQ was assessed by comparing FFQ-derived nutrient intakes against the average of two 24-h dietary recalls of 70 pregnant women. We used appropriate statistical methods to examine the nutrient correlation and level of agreement between the two figures (Pearson or Spearman correlation and Bland–Altman test, respectively). Calculation of the Mediterranean Diet Score was performed to evaluate participants’ adherence to the Mediterranean diet.
Statistically significant positive correlations, of medium strength, were observed for almost all macronutrient groups (ρs ranging from 0.326 to 0.538). Dietary fiber intake was the only nutrient where a weak correlation was identified (ρ = −0.106; P > 0.05). Mean intakes, derived from the FFQ, agreed with results from the 24-h recalls based on Bland–Altman analysis, with the agreement ranging between 94.3% and 98.6% for the macronutrient groups under examination. The calculation of the Mediterranean Diet Score revealed that Greek pregnant women's habits are in accordance with the principles of the Mediterranean diet.
The developed FFQ is a valid tool that could provide reliable nutrient intake assessment in studies monitoring dietary habits of pregnant women, a group where nutritional monitoring is essential but to date remains limited.
•Nutrition is an important factor affecting pregnancy outcomes.•A valid and short tool was developed for assessing nutrition habits of Greek pregnant women.•Greek pregnant women's nutrition is concordant with the principles of the Mediterranean diet.•The developed food frequency questionnaire can be easily used for nutrition monitoring during pregnancy.
Exercise during pregnancy may be beneficial provided that there are no contraindications. The aim of this study was to summarize and compare recommendations regarding exercise in pregnancy. Thus, a ...comparative descriptive review was conducted and included guidelines by the American College of Obstetricians and Gynecologists, the Society of Obstetricians and Gynaecologists of Canada and the Royal Australian and New Zealand College of Obstetricians and Gynaecologists. All compared guidelines recommend that pregnant women without contraindications should undertake physical activities regularly, however, the type of workout performed should be adjusted based on the previous exercise experience and the physical condition of each pregnant woman. A variation among the reviewed guidelines was identified on appropriate and inappropriate activities and on indications to interrupt exercise. To summarize, the adoption of an international up-to-date consensus regarding appropriate exercise during pregnancy may be beneficial in ensuring the safety of the pregnant women while promoting their physical and mental health.
Data on the association of nonalcoholic fatty liver disease (NAFLD) with subclinical cardiac damage are scanty. We performed a systematic review to provide comprehensive information on subclinical ...cardiac alterations among NAFLD subjects.
PubMed and the Cochrane Library were searched to identify studies comparing subclinical cardiac damage between NAFLD and healthy adults. We also searched PROSPERO to check for any similar meta-analysis in progress in order to avoid duplication with our study. Conference abstracts and the reference lists of relevant studies and systematic reviews were perused. The Newcastle-Ottawa quality assessment scale for case-control and cohort studies were used to assess study quality.
Seven studies were finally included in the meta-analysis (1 cross sectional and 6 case-control), with a total of 602 individuals (362 patients with NAFLD). Epicardial fat thickness were statistically significantly higher in patients with NAFLD than in controls (mean difference MD 1.17, 95% confidence interval CI 0.45-1.89,
=89%). Global longitudinal strain was lower in NAFLD, to a statistically significant degree (MD -3.17, 95%CI -5.09 to -1.24,
=89%). However, significant heterogeneity of the findings was observed.
Our findings indicate that NAFLD is related to subclinical cardiac damage. Further studies with a larger number of biopsy-proven NAFLD patients are needed to confirm this finding. Preventive and therapeutic interventions early in the course of the disease might decrease morbidity in this high-risk patient group.
