Knowledge about dietary fibre: a fibre study framework.

The objective of this work was to study the degree of knowledge about dietary fibre (DF), as influenced by factors such as gender, level of education, living environment or country. For this, a descriptive cross-sectional study was undertaken on a non-probabilistic sample of 6010 participants from 10 countries in different continents (Europe, Africa and America). The results showed that the participants revealed on average a positive but still low global level of knowledge, which alerts for the need to take some actions to further inform the population about DF and its role as a component of a healthy diet. The results also indicated differences between genders, levels of education, living environments and countries. The highest level of knowledge was revealed by the participants from female gender, with higher education and living in urban areas. Concerning the country, the best informed were the participants from Romania, followed by those from Portugal and Turkey while the least informed were from Egypt.

Intraoral fluoride levels after use of conventional and high-fluoride dentifrices.

OBJECTIVES: This study aimed to evaluate saliva and plaque as indicators of intraoral fluoride (F) levels after the use of conventional and high-fluoride dentifrices. MATERIALS AND METHODS: Subjects were randomly assigned to brush their teeth with conventional (1000 ppm F), high-fluoride (5000 ppm F), and placebo dentifrices (fluoride free) for 10 days, following a double-blind, crossover protocol. Saliva and plaque samples were collected on the morning of the 5(th) and 10th days, respectively at 1 and 12 h after brushing, and analyzed with an ion-selective electrode after HMDS-facilitated diffusion. Data were analyzed by two-way repeated measures ANOVA, Tukey's test and Spearman's correlation coefficient (p < 0.05). RESULTS: Plaque and salivary F levels were significantly increased after the use of conventional and high-fluoride dentifrices when compared to values obtained for placebo, except plaque 12 h after the use of conventional dentifrice. A positive and significant correlation was found between fluoride concentrations in plaque and saliva for both times of sample collection. CONCLUSION: Both indicators assessed were able to detect significant differences among treatments and between times after brushing. The use of a high-fluoride dentifrice is able to significantly increase intraoral fluoride levels throughout the day, being therefore a useful therapy for patients at high caries risk. CLINICAL RELEVANCE: A dentifrice with high fluoride concentration could be regarded as a useful therapy of F delivery for high caries-risk patients, since intraoral F levels were sustained throughout most of the day after using this formulation.

Relationship between Nutrition, Lifestyle Habits and Laboratory Parameters in Hypertensive Patients with/without Cognitive Dysfunction.

(1) Background: Cognitive dysfunction is a major concern in hypertensive patients. Lifestyle habits and nutrition influence laboratory parameters, with an impact on clinical course. The objective of the study was to evaluate nutrition and lifestyle habits in hypertensive patients with/without cognitive dysfunction and establish correlations to laboratory parameters. MATERIAL AND METHODS: 50 patients admitted to the Cardiovascular Rehabilitation Clinic in Târgu Mureș were enrolled in this study between March-June 2021. We evaluated their cognitive function, and they filled in a questionnaire about lifestyle and nutrition. Biochemical blood tests were performed using a Konelab Prime 60i analyzer. IBM-SPSS22 and GraphPad InStat3 were used for statistics. RESULTS: Mean age of hypertensive patients (n = 50) was 70.42 ± 4.82 (SD) years, half of them had cognitive dysfunction. Zinc deficiency was present in 74% of the subjects. The subgroup with cognitive dysfunction had significantly higher BMI (p = 0.009) and microalbuminuria (p = 0.0479), as well as significantly lower magnesium intake (p = 0.032) and cholesterol intake (p = 0.022), compared to those with normal cognitive status. CONCLUSIONS: Nutrition is in a close relationship with laboratory parameters; significant differences (microalbuminuria, cholesterol intake, BMI, etc.) are present between hypertensive patients with/without cognitive dysfunction. A healthy diet is important for the maintenance of metabolic balance, the achievement of optimal body weight, and the prevention of complications.

[Quality of life of consumers following a gluten-free diet. Results of a questionnaire survey in Hungary and Romania]. / A gluténmentesen táplálkozó fogyasztók életminosége. Magyarországi és romániai kérdoíves felmérés eredményei.

Introduction and aim: With the rising consumer's health awareness, especially towards patients with celiac disease, gluten has become a food ingredient to be avoided by many people expecting various positive health effects. The strict adherence of diet requires serious abandonments and lifestyle changes that affect directly their quality of life. The aim of the present study was to recognise the quality of life of Hungarian and Romanian consumers following a gluten-free diet as well as to explore the negative effects on them. Method: An online questionnaire survey was conducted upon 1155 Hungarian and Romanian respondents. Results: For gluten-free consumers, self-control was relatively easy to overcome, but their lifestyle was negatively affected by social events and dining out. In addition, diet adherence was a burden from both lifestyle and financial point of view. For Hungarian consumers, external factors such as price, choice, taste and availability of products had become a major obstacle, while Romanian ones were more likely to be affected by internal factors (product information, diet knowledge, lifestyle, self-control). Mandatory labelling of substances and products causing allergies and intolerances has achieved its purpose, as it has made it easier for consumers on diet to choose food and increased their confidence. Conclusions: The study points out that dieters' quality of life can be enhanced not only by general actions (improving the preparedness of out-of-home meal services and rationalising the price of products), but also through country-specific community intervention.

Smoking habits of pharmacy students attending the University of Medicine and Pharmacy in Targu Mures.

Smoking is common among health professional students. The aim of this study was to assess the smoking habits of the pharmacy students attending the University of Medicine and Pharmacy in Târgu Mureș (UMPh TM), Romania. Material and methods: Smoking habits and attitudes toward smoking among 414 pharmacy students attending UMPh TM (86% female) were evaluated using a self-completed questionnaire. Results: The rate of smoking increases during the time students attend the university (24.1% to 33.3% from 1st to 5th year) and males are significantly are more likely to smoke than females (41.4% vs. 27.3%, p=0.042). 36.9% of the smoking pharmacy students are tobacco-dependent, and 40.4% of smokers started daily smoking at the age of 16-19. We found significant differences between smoker and non-smoker pharmacy students regarding their attitudes toward smoking and tobacco control policies, with non-smokers being more supportive of smoke-free policies. Conclusions: Prevention programs and education have a very important role in decreasing the percentage of smokers and support for smokefree policies, but it is critical to begin such programs early in their university training.

Combined effects of subchronic exposure to lead, mercury and alcohol on the spontaneous and evoked cortical activity in rats.

The aim of this study was to investigate the effects of a combination of well-known neurotoxic heavy metals, lead and mercury, with ethanol. For 12 weeks, young adult male Wistar rats were given plain tap water or water containing 5% (v/v) ethanol to drink, and were treated with two doses of lead acetate or mercuric chloride by gavage. Accordingly, there was a water-drinking and an alcohol-drinking control group. After the treatment period, spontaneous and stimulus-evoked activity from the somatosensory, visual and auditory cortical areas was recorded. The frequency spectrum of the spontaneous activity, as well as latency and duration of the evoked potential were analysed. A shift in frequency was observed in the electrocorticogram, and lengthened latency and duration times in the evoked potentials. Alcohol seemed to influence the effect of the metals. Combined exposure to heavy metals and regular alcohol consumption may result in more severe central and/or peripheral neurotoxic outcomes.

Changes in the central nervous activity of rats treated with dimethoate in combination with other neurotoxicants in different phases of ontogenesis.

Organophosphates are usually found in the environment with other pesticides and with pollutants of industrial origin can cause combined exposure involving unknown interactions between the agents. In this study, female Wistar rats were given 1/25 LD50 of dimethoate by gavage, combined with the same LD50 fractions of propoxur and cypermethrin or with arsenic (6.66 mg kg(-1)). The doses were given from day 5 to 15 of pregnancy, or that plus for the 4 weeks of lactation, or that plus 8 weeks for the male offspring after weaning. Control rats received distilled water. Electrophysiological recording was done when the male offspring reached 12 weeks of age. Spontaneous activity and evoked potentials from the somatosensory, visual and auditory cortex; and conduction velocity and absolute and relative refractory periods of the tail nerve were measured. The general trend was a shift of the spontaneous cortical activity to higher frequencies and increase in the evoked potential latency. The results showed that combined exposure to several environmental toxicants could be more harmful than the effects of each substance alone, indicating the importance of combination toxicology in modelling human effects. Furthermore, these results emphasize the importance of avoiding toxic exposures in pregnant and nursing women.
