AbstractObjectiveThe study aimed to evaluate the dietary vitamin B6 intake and determine the vitamin B6 concentration in blood samples of German vegans.Design and settingCross-sectional study with 33 examination sites all over Germany.SubjectsNinety-three vegans (50 females) with a mean (±standard deviation (SD)) age of 43.7 ± 15.7 years who took no vitamin supplements.MethodsDietary intake was assed using a semi-quantitative food-frequency questionnaire. Erythrocyte aspartate aminotransferase activity coefficient (EAST-AC) was calculated as the ratio of stimulated (pyridoxal 5'-phosphate added) to unstimulated activity in blood samples that were provided after an overnight fast.ResultsMean ± SD vitamin B6 intake was 2.83 ± 0.98 mg day−1 and mean ± SD protein intake was 56.6 ± 21.7 g day−1. Of the participants 4% showed vitamin B6 intakes lower than daily recommended intakes for Germany, 16% showed EAST-AC > 1.85, and a further 58% showed EAST-AC of 1.5–1-85. Moderate vegans were affected to a lesser extent than strict vegans. None of the established confounders was a significant predictor of EAST-AC. In logistic regression analyses the contribution of nutriments and cereals to pyridoxine intake was the only predictor of EAST-AC classified as < 1.85 and ≥ 1.85, respectively.ConclusionsIn spite of the high total intake of vitamin B6, an adequate concentration in blood samples could not be realised for a majority of the participants. Due to the health implications of a marginal pyridoxine status, vegans should be encouraged to include foods with a high bioavailability of pyridoxine, such as beans, lentils and bananas, in the daily diet.

Abstract Objective: B-vitamins affect brain function through multiple pathways. Given limited evidence on the relationship between dietary intake of these vitamins and psychological disorders, we examined dietary intake of vitamin B6-9-12 in relation to psychological disorders among Iranian women. Design: Cross-sectional study. Dietary intake was assessed using a valid and reliable FFQ. To assess psychological disorders, we used a version of the Depression Anxiety Stress Scale-21 validated in Iran. Setting: Ten public health centres in southern Tehran, Iran. Participants: A total of 447 female participants aged 20–50 years. Results: The median values of vitamin B6 (pyridoxine), B9 (folate) and B12 (cobalamin) were 1·30 mg/d, 313·89 µg/d and 3·99 µg/d, respectively. After adjustment for potential confounders, dietary vitamin B6 intake was associated with lower odds of depression (OR: 0·54; 95 % CI: 0·31, 0·95; Ptrend: 0·03). However, there was a positive association between dietary vitamin B12 intake with the odds of depression (OR: 2·05; 95 % CI: 1·17, 3·60; Ptrend: 0·01) and psychological distress (OR: 2·00; 95 % CI: 1·17, 3·41; Ptrend: 0·01). No association was found between vitamin B9 with any psychological disorders. Conclusions: Women with higher dietary intakes of vitamin B6 had lower likelihood of depression. However, women with higher dietary intake of vitamin B12 had higher odds of depression and psychological distress. Future prospective studies in different populations are needed to clarify whether B-vitamin deficiency is a cause or consequence of psychological disorders.

Objective: This study aimed to investigate the associations between dietary one-carbon metabolism-related nutrients (betaine, choline, methionine, folate, vitamin B6, and vitamin B12) and fluorosis among the Chinese population in an area known for coal-burning fluorosis.Methods: A cross-sectional study was conducted, with 653 fluorosis patients and 241 non-fluorosis participants. Dietary intake was acquired using a validated semi-quantitative 75-item food frequency questionnaire. The risk associations were assessed by unconditional logistical regression.Results: We observed a significant inverse association between dietary betaine, total choline, methionine, folate, vitamin B6, and choline species and fluorosis. The adjusted OR (95% CI) in the highest quartile of consumption compared with the lowest were 0.59 (0.37–0.94) (P-trend = 0.010) for betaine intake, 0.45 (0.28–0.73) (P-trend = 0.001) for total choline intake, 0.45 (0.28–0.72) (P-trend &lt; 0.001) for methionine intake, 0.39 (0.24–0.63) (P-trend &lt; 0.001) for folate intake, 0.38 (0.24–0.62) (P-trend &lt; 0.001) for vitamin B6 intake, and 0.46 (0.28–0.75) (P-trend = 0.001) for total choline plus betaine intake. Dietary intakes of choline-containing compounds, phosphatidylcholine, free choline, glycerophosphocholine, and phosphocholine were also inversely associated with lower fluorosis (all P-trend &lt; 0.05). No significant associations were observed between dietary vitamin B12 or sphingomyelin and fluorosis.Conclusion: The present study suggested that the higher dietary intakes of specific one-carbon metabolism-related nutrients, such as betaine, choline, methionine, folate, and vitamin B6, are associated with lower fluorosis prevalence.

We aimed to differentiate gut microbiota composition of overweight/obese and lean subjects and to determine its association with clinical variables and dietary intake. A cross-sectional study was performed with 96 overweight/obese subjects and 32 lean subjects. Anthropometric parameters were positively associated with Collinsella aerofaciens, Dorea formicigenerans and Dorea longicatena, which had higher abundance the overweight/obese subjects. Moreover, different genera of Lachnospiraceae were negatively associated with body fat, LDL and total cholesterol. Saturated fatty acids (SFAs) were negatively associated with the genus Intestinimonas, a biomarker of the overweight/obese group, whereas SFAs were positively associated with Roseburia, a biomarker for the lean group. In conclusion, Dorea formicigenerans, Dorea longicatena and Collinsella aerofaciens could be considered obesity biomarkers, Lachnospiraceae is associated with lipid cardiovascular risk factors. SFAs exhibited opposite association profiles with butyrate-producing bacteria depending on the BMI. Thus, the relationship between diet and microbiota opens new tools for the management of obesity.

Abstract Background Both capillary and venous blood samples have been interchangeably used for the diagnosis of malaria in Ethiopia. However, Plasmodium parasites are thought to be more concentrated in capillary than in venous blood. Hence, selecting a sample source where parasites are more concentrated is indispensable approach in order to maximize the accuracy of blood film microscopy. Therefore, the present study aimed to compare the detection rate and the parasitemia level of Plasmodium species from conventional capillary and venous blood films, and buffy coat preparations. Methods A facility based cross-sectional study was conducted from Feburary to March 2020 among 210 febrile patients attending Hamusite health center, northwest Ethiopia. Capillary and venous blood samples were collected and buffy coat was prepared from each sample. Thin and thick blood films were prepared, stained, and examined microscopically following standard protocol. Data were analysed using Statistical Package for Social Sciences Software version 20 and Med-Calc software version 19.3. Results Capillary blood buffy coat (61/210, 29.0%) had significantly higher detection rate as compared to capillary (48/210, 22.9%) and venous (42/210, 20.0%) blood films (p < 0.001). However, no significant difference was observed between capillary and venous blood films (p = 0.070) in detecting Plasmodium species. The highest and the lowest mean asexual stage parasite counts were found in capillary blood buffy coat (4692.88) and venous blood (631.43) films, respectively showing significant variations (p < 0.001). Mean gametocyte count was also highest in capillary blood buffy coat (3958.44). As compared to capillary blood buffy coat, the sensitivity of venous blood buffy coat, capillary blood film and venous blood film were 73.8, 78.7, 68.9%, respectively. Conclusion Capillary blood buffy coat samples showed the highest sensitivity in detecting and quantitating malaria parasites that its use should be promoted in clinical settings. However, conventional capillary and venous blood films could be used interchangeably.

Chinese College Students

This study aims to explore the association between restrained eating, body image, and dietary intake among Chinese college students. This cross-sectional study included 1301 college students at two universities in Hunan Province. Electronic questionnaires were used to collect information including students’ demographic characteristics, restrained eating, perception of body weight, body satisfaction, and dietary intake. Anthropometric measurements were collected to calculate body mass index (BMI). The prevalence of high restrained eating was 52.8%. Students who were dissatisfied with their bodies or overestimated their body weight showed a higher tendency toward high restrained eating (p < 0.05). Students with high restrained eating tended to eat fruits and eggs more frequently, while the frequency of eating domestic animals and poultry, sugar-sweetened beverages, and fast food were the opposite. Moreover, high restrained eating was a risk factor for low dietary diversity (odds ratio (OR) = 1.384, 95% confidence interval: 1.002~1.912). The high incidence of restrained eating among Chinese college students and its energy-restricted diets that may lead to possible health implications require attention. Further studies are needed to investigate the characteristics of college students’ restrained eating to tailor appropriate interventions for forming positive body images and promoting healthy eating behaviors, thus, improving dietary quality.

Abstract Objective We sought to evaluate associations between postpartum plasma adipokine concentrations among women with a history of preeclampsia (PE) without severe features (MPE), PE with severe features (SPE), and no PE (NPE). We also investigated relationships between adipokines and computed tomography (CT)-quantified measures of visceral fat (VF) area (VFA) and subcutaneous fat area (SCFA). Study Design We performed a secondary analysis of data collected as part of a previously performed cross-sectional study at our institution. Women with and without a history of PE were recruited in 10 years after delivery. VFA and SCFA measures were performed by CT scan. Anthropometric data and peripheral blood samples from subjects were collected concurrently. Results Plasma adiponectin concentrations (µg/mL) were significantly lower among MPE (18.5 ± 7.1) compared with NPE (27.3 ± 13.8) and SPE (25.7 ± 9.6). Leptin (p = 0.32) and resistin (p = 0.93) concentrations were similar among the groups. Adiponectin concentrations more closely aligned with VFA (β = −0.001, p = 0.03), while resistin concentrations trended toward correlating with SCFA (β = 0.02, p = 0.05). Leptin was not preferential to VFA or SCFA. Conclusion VF distribution may contribute to the variation in PE phenotype. Adiponectin specifically may be a promising marker representing VFA.
