Since 1990, due to political and legislative changes, immigration from the former Soviet Union to the United States has increased significantly. Population reports from 1988 indicate that there were approximately 406,000 Soviet immigrants in the United States at that time. This number is expected to increase due to the Immigration Reform Act of 1990, which raised the Soviet refugee ceiling to 50,000 per year. Currently, very little is known about the health status and health practices of this population, although some published data indicate that life expectancy and infant mortality rates compare poorly with those of the general population in the United States. Although the former Soviet republics experienced universal health care coverage, there was little emphasis on promoting a healthy lifestyle. Heavy cigarette use, high alcohol intake, poor dietary intake, little attention to physical fitness, and crowded living conditions have been described. Environmental pollution and poor occupational safety are common and have contributed to the health problems of the population. As the influx of immigrants continues, the consequences of these health conditions will impose a burden on health care services in this country. As with any immigrant group, an understanding of the potential health conditions and cultural values can facilitate appropriate medical care. This research was conducted to explore these issues. Interviews and a physical assessment were conducted with 30 adults from the former Soviet Union. The major health problems identified included various dental conditions requiring treatment, obesity, and the absence of basic health screening measures such as cholesterol testing, high blood pressure screening, Pap smears, and mammograms. The authors also identified a need for translators and for education regarding preventative self-care, such as breast self-examinations.

Molecules of 4,4'-dimethyl-2-hydroxy-6-oxocyclohexene-1-carboxylic acid, C(9)H(12)O(4), crystallize at 295 K in a modulated superstructure with five half-molecules in the asymmetric unit; each molecule is located on one of the mirror planes of the space group Cmc2(1). Reflections with k not equal 5n are systematically weak; a satisfactory refinement can be obtained in a Cmcm pseudocell having b' = b/5. The important modulation involves small rotations of the molecules around axes perpendicular to the mirror plane; there is also an up/down disorder of the CMe(2) fragment in four of the five molecules (two molecules with occupancy factors ca 4:1; two with occupancy factors ca 3:2). The modulation is a response to packing problems that can be traced to the differences between the thin, electron- and oxygen-rich 'head' of the molecule and the thicker, methyl-rich 'tail'. At 130 K the length of b is reduced by 2/5 and the Pmnb structure is ordered. Both structures can be described as modulated variants of the Cmcm substructure; the wavevectors are 2b'*/5 for the room-temperature structure and b'*/2 for the low-temperature structure, where b'* is the reciprocal axis of the subcell. The structure at room temperature can also be understood as a hybrid of the fully disordered pseudocell structure and the ordered structure that is found at low temperature.

Breastfeeding is possible with children who have phenylketonuria. Based on the decisions made by the breastfeeding mother and the infant's physician, there are multiple methods of management which can be utilized to provide breast milk for the infant with PKU. This article describes some of the methods that have been used to manage the treatment of phenylketonuria when a mother chooses to breastfeed.
