TL;DR: Measurements that promote prenatal and postnatal growth may reduce deaths from ischaemic heart disease and may be especially important in boys who weigh below 7.5 pounds (3.4 kg) at birth.

TL;DR: The lack of association between size at birth and maternal energy and protein intake but strong associations with folate status and with intakes of foods rich in micronutrients suggest that micronUTrients may be important limiting factors for fetal growth in this undernourished community.
Abstract: One third of the Indian babies are of low birth weight ( Mothers were short (151.9 ± 5.1 cm) and underweight (41.7 ± 5.1 kg) and had low energy and protein intakes at 18 wk (7.4 ± 2.1 MJ and 45.4 ± 14.1 g) and 28 wk (7.0 ± 2.0 MJ and 43.5 ± 13.5 g) of gestation. Mean birth weight and length of term babies were also low (2665 ± 358 g and 47.8 ± 2.0 cm, respectively). Energy and protein intakes were not associated with birth size, but higher fat intake at wk 18 was associated with neonatal length (P Erythrocyte folate at 28 wk gestation was positively associated with birth weight (P < 0.001). The lack of association between size at birth and maternal energy and protein intake but strong associations with folate status and with intakes of foods rich in micronutrients suggest that micronutrients may be important limiting factors for fetal growth in this undernourished community.

TL;DR: The utilisation studies showed that FFQ were most commonly used in cross-sectional surveys, with ninety-three of the FFQ being designed to be disease-specific, and mean correlation coefficients were highest for Ca and fat, and lowest for vitamin A and vegetables.
Abstract: A review of the literature concerning the design, utilisation and validation of food-frequency questionnaires (FFQ) has been carried out using a semi-systematic approach to obtaining, reviewing and extracting data from articles. Databases were searched from 1980 to 1999. The present review identified 227 validation (from 1980 to September 1999) and 164 utilisation (for 1998 only) studies. A number of design issues have been evaluated through the present review. These include: the need to consider how portion sizes have been described, self-defined giving higher mean correlations; how an FFQ was administered, interviewer-administered giving higher mean correlations for some nutrients; how many items to include on an FFQ, those with the largest number of items having higher correlations. Validation techniques were described. Most validation studies involved comparing an FFQ against another dietary assessment method; only 19 % compared an FFQ to a biomarker. Measurement differences were most commonly assessed by correlation coefficients as opposed to other more appropriate methods. Mean correlation coefficients were highest for Ca and fat, and lowest for vitamin A and vegetables. The utilisation studies showed that FFQ were most commonly used in cross-sectional surveys, with ninety-three of the FFQ being designed to be disease-specific. The present review results were presented to a group of experts and a consensus arrived at concerning the development, validation and use of FFQ. Recommendations derived from the consensus arising from the literature review are presented as an appendix to the present paper.

TL;DR: Findings from the first ‘before/after’ study of food consumption in a highly deprived area of a British city experiencing a sudden and significant change in its food-retail access are reported.
Abstract: Within a context of public policy debate in the United Kingdom on social exclusion, health inequalities, and food poverty, the metaphor of the 'food desert' caught the imagination of those involved in policy development. Drawing from a major cross-disciplinary investigation of food access and food poverty in British cities, the authors report in this paper findings from the first 'before/after' study of food consumption in a highly deprived area of a British city experiencing a sudden and significant change in its food-retail access. The study has been viewed as the first opportunity in the United Kingdom to assess the impact of a non-healthcare intervention (specifically a retail-provision intervention) on food-consumption patterns, and by extension diet-related health, in such a deprived, previously poor-retail-access community. The paper offers evidence of a positive but modest impact of the retail intervention on diet, and the authors discuss the ways in which their findings are potentially significant in the context of policy debate.

TL;DR: 2007 Guidelines for the Management of Arterial Hypertension : The Task Force for the management of Arterspertension of the European Society ofhypertension (ESH) and of theEuropean Society of Cardiology (ESC).
Abstract: Because of new evidence on several diagnostic and therapeutic aspects of hypertension, the present guidelines differ in many respects from the previous ones. Some of the most important differences are listed below:
1. Epidemiological data on hypertension and BP control in Europe.
2. Strengthening of the prognostic value of home blood pressure monitoring (HBPM) and of its role for diagnosis and management of hypertension, next to ambulatory blood pressure monitoring (ABPM).
3. Update of the prognostic significance of night-time BP, white-coat hypertension and masked hypertension.
4. Re-emphasis on integration of BP, cardiovascular (CV) risk factors, asymptomatic organ damage (OD) and clinical complications for total CV risk assessment.
5. Update of the prognostic significance of asymptomatic OD, including heart, blood vessels, kidney, eye and brain.
6. Reconsideration of the risk of overweight and target body mass index (BMI) in hypertension.
7. Hypertension in young people.
8. Initiation of antihypertensive treatment. More evidence-based criteria and no drug treatment of high normal BP.
9. Target BP for treatment. More evidence-based criteria and unified target systolic blood pressure (SBP) (<140 mmHg) in both higher and lower CV risk patients.
10. Liberal approach to initial monotherapy, without any all-ranking purpose.
11. Revised schema for priorital two-drug combinations.
12. New therapeutic algorithms for achieving target BP.
13. Extended section on therapeutic strategies in special conditions.
14. Revised recommendations on treatment of hypertension in the elderly.
15. Drug treatment of octogenarians.
16. Special attention to resistant hypertension and new treatment approaches.
17. Increased attention to OD-guided therapy.
18. New approaches to chronic management of hypertensive disease

TL;DR: In this article, the British Medical Association forwarded to all British doctors a questionnaire about their smoking habits, and 34440 men replied, with few exceptions, all men who replied in 1951 have been followed for 20 years.
Abstract: In 1951 the British Medical Association forwarded to all British doctors a questionnaire about their smoking habits, and 34440 men replied. With few exceptions, all men who replied in 1951 have been followed for 20 years. The certified causes of all 10 072 deaths and subsequent changes in smoking habits were recorded. The ratio of the death rate among cigarette smokers to that among lifelong non-smokers of comparable age was, for men under 70 years, about 2:1, while for men over 70 years it was about 1-5:1. These ratios suggest that between a half and a third of all cigarette smokers will die because of their smoking, if the excess death rates are actually caused by smoking. To investigate whether this is the case, the relation of many different causes of death to age and tobacco consumption were examined, as were the effects of giving up smoking. Smoking caused death chiefly by heart disease among middle-aged men (and, with a less extreme relative risk, among old men,) lung cancer, chronic obstructive lung disease, and various vascular diseases. The distinctive features of this study were the completeness of follow-up, the accuracy of death certification, and the fact that the study population as a whole reduced its cigarette consumption substantially during the period of observation. As a result lung cancer grew relatively less common as the study progressed, but other cancers did not, thus illustrating in an unusual way the causal nature of the association between smoking and lung cancer.
