Dietary beliefs in the Baltic republics.

OBJECTIVES: As beliefs and knowledge about the possible effects of foods on health can influence food behaviours, this study examined selected dietary beliefs in the Baltic countries and the association of beliefs related to salt intake and to types of fat with food behaviours. DESIGN: A cross-sectional study. SETTING: Data from three surveys conducted in Estonia, Latvia and Lithuania in the summer of 1997 were used to describe the prevalence of dietary beliefs in these countries and to investigate the association between beliefs and behaviours (using logistic regression). SUBJECTS: Representative national samples of adults were selected in each country (Estonia, n = 2018; Latvia, n = 2308; Lithuania, n = 2153). RESULTS: Misunderstood concepts (myths) related to dietary salt, types of fat, meat consumption and bread and potatoes were observed in high proportions of the population. Education level was an important correlate of beliefs related to salt intake and types of fat, people with a higher education level being more likely to be familiar with these issues. Correct beliefs were not consistently associated with healthier behaviours (e.g. less frequent use of salt at the table and use of non-animal fats for cooking), except for salt intake in Estonia. CONCLUSIONS: Several misunderstood dietary concepts (myths) are still prevalent in the Baltic countries. Correct beliefs related to salt intake and types of fat were not consistent predictors of healthier food behaviours. In-depth qualitative investigations are needed to better describe and understand dietary beliefs and attitudes in the Baltic countries, and to identify barriers to the adoption of healthy food habits

Imitation of β-lactam binding enables broad-spectrum metallo-β-lactamase inhibitors

Carbapenems are vital antibiotics, but their efficacy is increasingly compromised by metallo-beta-lactamases (MBLs). Here we report the discovery and optimization of potent broad-spectrum MBL inhibitors. A high-throughput screen for NDM-1 inhibitors identified indole-2-carboxylates (InCs) as potential beta-lactamase stable beta-lactam mimics. Subsequent structure-activity relationship studies revealed InCs as a new class of potent MBL inhibitor, active against all MBL classes of major clinical relevance. Crystallographic studies revealed a binding mode of the InCs to MBLs that, in some regards, mimics that predicted for intact carbapenems, including with respect to maintenance of the Zn(II)-bound hydroxyl, and in other regards mimics binding observed in MBL-carbapenem product complexes. InCs restore carbapenem activity against multiple drug-resistant Gram-negative bacteria and have a low frequency of resistance. InCs also have a good in vivo safety profile, and when combined with meropenem show a strong in vivo efficacy in peritonitis and thigh mouse infection models.Peer reviewe

Growing up to belong transnationally : parent perceptions on identity formation among Latvian emigrant children in England

As a result of the wide availability of social media, cheap flights and free intra-EU movement it has become considerably easier to maintain links with the country of origin than it was only a generation ago. Therefore, the language and identity formation among children of recent migrants might be significantly different from the experiences of children of the previous generations. The aim of this paper is to examine the perceptions of parents on the formation of national and transnational identity among the ‘1.5 generation migrant children’ – the children born in Latvia but growing up in England and the factors affecting them. In particular, this article seeks to understand whether 1.5 generation migrant children from Latvia construct strong transnational identities by maintaining equally strong ties with their country of origin and mother tongue and, at the same time, intensively creating networks, learning and using the language of the new home country. The results of 16 semi-structured in-depth interviews with the parents of these children reveal that the 1.5 generation Latvian migrants are on a path of becoming English-dominant bilinguals. So far there is little evidence of the development of a strong transnational identity among 1.5 generation migrant children from Latvia. Instead, this study observed a tendency towards an active integration and assimilation into the new host country facilitated by their parents or occurring despite their parents’ efforts to maintain ties with Latvia. These findings suggest that rather than the national identity of the country of origin being supplemented with a new additional national identity – that of the country of settlement – the identity of the country of origin becomes dominated by it instead

Analiza usuwania BZT5, ChZT i zawiesiny ogólnej w sztucznym ekosystemie mokradłowym o poziomym przepływie podpowierzchniowym, zlokalizowanym na Łotwie

This study aims to evaluate the performance of subsurface flow constructed wetland in Latvia which was established to receive storm water from surface runoff from a farmjard in agricultural area. As a part of this study, subsurface horizontal flow wetlands was monitored, in order to evaluate the changes in the efficiency of treatment depending on biological factors. The efficiency of horizontal subsurface flow constructed wetland was evaluated by comparing the concentration of total suspended solids (TSS), biochemical oxygen demand (BOD5) and chemical oxygen (COD) at inlet and outlet of the wetland depending on temperature and pH. Since June 2014, water quality monitoring in a research site in the farm “Mezaciruli”, Zaļenieku parish, Jelgava region has been carried out to treat the point source agricultural runoff from the impermeable pavements. The analysis of the data obtained in the monitoring allows to draw conclusions about the influence of certain factors in the subsurface flow constructed wetlands under the climate and environmental conditions in Latvia

Macronutrient and food intake in the Baltic republics.

OBJECTIVE: The objective of this study was to describe mean macronutrient and food intakes in the Baltic republics, with a particular focus on fat, vegetable and fruit consumption. DESIGN: Cross-sectional study. SETTING: Data from surveys conducted in Estonia, Latvia and Lithuania in the summer of 1997 were used. Information was collected using a 24 h recall of dietary intake and an interviewer-administered questionnaire. SUBJECTS: Representative national samples of adults were selected. All those with information from the dietary recall were included in the study (Estonia: n = 2015; Latvia: n = 2300; Lithuania: n = 2094). RESULTS: The mean proportion of energy from fat was high in each country, but particularly in Lithuania (44%) and Latvia (42%) compared with Estonia (36%). In contrast, percentage energy from carbohydrate, protein and alcohol was higher in Estonia. Mean protein intake was generally sufficient if not high in some population sub-groups. Median vegetable intakes were very low (<200 g/day) in each country, particularly in Latvia. While 78% of the Lithuanian respondents consumed vegetables daily, this was the case in only 60% of the Latvian and 48% of the Estonian respondents. CONCLUSIONS: This study suggests that there is a pressing need to replace high-fat energy dense foods by foods rich in complex carbohydrates and dietary fibre, such as vegetables and fruits, in the Baltic republics. This could provide the populations with a reduced risk and increased protection against non-communicable diseases. These issues will need to be tackled through comprehensive food and nutrition policies and health promotion campaigns

Physical inactivity in the Baltic countries.

Physical inactivity is a known risk factor for heart disease and obesity, two major health problems in the Baltic Republics. This study examined patterns of physical activity level in these countries, and correlates of leisure-time sedentary behavior. Data from three national surveys of adults conducted in Estonia, Latvia, and Lithuania in 1997 were used. Respondents who provided information on their activity level were included in this study (Estonia: n = 2,018; Latvia: n = 2,303; Lithuania: n = 2,140). One in three Estonians and one in five Latvians and Lithuanians had a low physical activity level at work. Half the respondents (Lithuania: 60%, Latvia: 52%, Estonia: 43%) participated only in sedentary activities during their leisure time. Leisure-time sedentarity was inversely related to education level in men and women and with income in men. It was also associated with smoking in men and with inadequate vegetable intake in men and women. Sedentary behavior during leisure time should be a public health issue in the Baltic Republics. Health promotion strategies aiming at increasing leisure-time physical activity level will need to target the general population, but particularly individuals from lower socioeconomic strata
