Anaemia in pregnant women before and after the mandatory fortification of wheat and corn flours with iron

Objective: To estimate the frequency of anaemia in pregnant women before and after the fortification of flours with Fe. Design: Retrospective study developed from secondary data obtained from medical records. Setting: Two health units in Rio de Janeiro, Brazil. Subjects: Socio-economic, demographic, obstetric and Hb concentration data were collected of 778 pregnant women attending prenatal care. Two study groups were created: the first referred to the period before fortification (G1, n 391), including women whose parturition happened before June 2004; and the second referred to the period after fortification (G2, n 387), including women whose last menstrual cycle happened after June 2005. The Hb cut-off point adopted for anaemia diagnosis was <11.0 g/dl. Results: In linear regression models, when Hb concentration was expressed as a dependent variable, women in G2 presented Hb concentration 0.26 g/dl and 0.36 g/dl higher during the second and third trimesters of pregnancy, respectively, compared with G1. In logistic regression models where the dependent variable was anaemia during the second and third trimesters, it was verified that being a member of G2 was a protective factor against anaemia in the third trimester. Regarding the presence of anaemia at any gestational moment, it was verified that being a member of G2 represented a protective factor against anaemia during pregnancy. Conclusions: Results indicate the protective effect of the fortification of flours with Fe in the fight against gestational anaemia, contributing to prevention and control of this nutritional disorder among pregnant women.

Neo-Assyrian concepts of fortification

The major cities of the Neo-Assyrian Empire were not only home to impressive palaces and temples, but they were also equipped with strong fortifications. The city walls were not only meant to keep out potential enemies, but by demonstrating Assyria’s power to any approaching person, they served an ideological purpose, as well. However, military efficiency was just as crucial, since, over its entire history, the empire repeatedly faced internal and external threats and could not have afforded to lose any of its urban centers which were essential to maintaining control over the various provinces or geographic regions associated with them. The study of Neo-Assyrian fortifications relies on evidence provided by archaeological excavations, the study of Assyrian reliefs and information from cuneiform texts. Even though these sources help us reconstruct the appearance of the town defenses, the question of why the individual fortification systems were built in a specific way cannot be addressed by these means alone. Remote sensing offers an opportunity to view the course and placement of the city walls within their topographical context. Furthermore, geographical information systems (GIS) offer a tool to illustrate the distribution of the strongly fortified Assyrian towns, thereby allowing us to recognize patterns and functions of regional fortification systems during the Neo-Assyrian period.

Folic acid fortification, maternal obesity and neural tube defects: Policy implications

In 1996, the Food and Drug Administration (FDA) mandated that beginning in January 1998, flour and other enriched grain products be fortified with 140 μg of folic acid per 100 g of grain to prevent neural tube defects (NTDs) that occur in approximately 1 in 1,000 pregnancies in the United States (U.S.). Although this program has demonstrated important public health effects, it is argued that current fortification levels may not be enough to prevent all folic acid-preventable NTD cases. This study reviews published literature, on folic acid fortification in the U.S. and countries with mandatory folic acid fortification programs reported after 1992 and through January 2008. Published studies are evaluated to determine if the current level of folic acid fortification in the U.S. is adequate to prevent the most common forms of NTDs (spina bifida and anencephaly), particularly among overweight and obese women. ^ Although consistent improvement in blood folate levels of child bearing age women is reported in almost all studies, the RBC folate concentration has not reached the level associated with the most significant reduction of risk for NTDs (906 nmol/L); approximately half of the potentially preventable NTDs are prevented by fortification at the current U.S. level. Furthermore, the blood folate status of women in higher BMI categories (obese or overweight) has not improved as much as among women in lower BMI categories. Therefore, women classified as overweight or obese have not benefited from the preventive effects of folic acid fortification as much as normal or underweight women. ^ To reduce risk of folate preventable NTDs, especially in overweight and obese women, it may be necessary to increase the current level of folic acid fortification. However, further research is required to determine the optimal levels of fortification to achieve this goal without causing adverse health effects in the general population. ^

Fortification and Frontier: The Project Drawn up by Juan Martín Zermeño for Puebla de Sanabria in 1766

Following the death of engineer General Jorge Próspero de Verboom in 1744 and after a few years of transition in the management of Spanish fortifications, Juan Martín Zermeño took on the role, initially with a temporary mandate, but then definitively during a second period that ran from 1766 until his death in 1772. He began this second period with a certain amount of concern because of what had taken place during the last period of conflict. The Seven Years War (1756–1763) which had brought Spain into conflict with Portugal and England in the Caribbean had also lead to conflict episodes along the Spanish–Portuguese border. Zermeño’s efforts as a planner and general engineer gave priority to the northern part of the Spanish–Portuguese border. After studying the territory and the existing fortifications on both sides of the border, Zermeño drew up three important projects in 1766. The outposts that needed to be reinforced were located, from north to south, at Puebla de Sanabria, Zamora and Ciudad Rodrigo, which is where he is believed to have come from. This latter township already had a modern installation built immediately after the war of the Spanish Succession and reinforced with the Fort of La Concepción. However, Zamora and Puebla de Sanabria had some obsolete fortifications that needed modernising. Since the middle of the 15th century Puebla de Sanabria had had a modern castle with rounded turrets, that of the counts of benavente. During the 16th and 17th centuries it had also been equipped with a walled enclosure with small bastions. During the war of the Spanish Succession the Portuguese had enlarged the enclosure and had erected a tentative offshoot to the west. In order to draw up the ambitious Puebla de Sanabria project Zermeño had the aid of some previous reports and projects, such as those by the count of robelin in 1722, the one by Antonio de Gaver in 1752, and Pedro Moreau’s report dated June 1755. This study includes a technical analysis of Zermeño’s project and its strategic position within the system of fortifications along the Spanish–Portuguese border.

All map collar and inset information is also available as part of the raster image, including any inset maps, profiles, statistical tables, directories, text, illustrations, or other information associated with the principal map. This map shows Revolutionary War features such as positions of troops, redoubts, batteries, and forts, etc. It also shows features such as roads, drainage, selected public buildings and residences, and more. Relief is shown by hachures. This layer is part of a selection of digitally scanned and georeferenced historic maps of Massachusetts from the Harvard Map Collection.
