Q: Abstract: Seventy-six white and black low-income families were interviewed weekly during 1 month to determine how much they spent on food using Food Stamps, WIC coupons, and cash and how much additional food they obtained from different food and meals programs. After families had received their public assistance and Food Stamp allotments for the month, a 24-hour recall was obtained each week from each family member so that food intake could be monitored from the recalls as food-buying resources were depleted. Although families bought most of their food the first 2 weeks, they maintained a relatively constant food intake through the last week of the month. However, when nutrient intakes were compared with Recommended Dietary Allowances, the diets were found to be well supplied in protein, ascorbic acid, thiamin, niacin, riboflavin, vitamin B-12, vitamin A, and phosphorus, and inadequately supplied in vitamin B-6, vitamin D, vitamin E, iron, calcium, magnesium, zinc, and pantothenic acid. Since that finding was true not just at the end of the month but from the beginning, it indicated that the nutrition problems of low-income families are not intermittent, but continuous.

Q: Abstract: The aim of this study was to investigate the blood coagulation changes in three patients with homocystinuria, in baseline condition and during therapy. At baseline, antithrombin III activity and factor VII levels were reduced in all three patients; antithrombin III protein and protein C antigen were also slightly lowered in one patient, and factor X in another. beta-Thromboglobulin, a measure of platelet activation, was increased in one case. During pyridoxine treatment, antithrombin III activity was rapidly restored to normal; factor VII increased and beta-thromboglobulin decreased. These data suggest that, in addition to platelet activation, abnormalities of blood clotting, and particularly reduction of antithrombin III, may play a role in the thrombotic tendency associated with homocystinuria. The nature of these clotting alterations is still uncertain, but their improvement during active metabolic treatment suggests that the defect in amino acid transsulfuration of homocystinuria may directly affect synthesis or activity of some liver-dependent clotting factors.

Q: Abstract: The effectiveness of neostigmine 0.07 mg kg-1 and edrophonium 0.8 mg kg-1 as antagonists of profound neuromuscular blockade induced by vecuronium 0.1 mg kg-1 or atracurium 0.5 mg kg-1 was studied in 59 healthy patients. The antagonists were administered 5 min after total ablation of the twitch response and the end-point of recovery was a train-of-four ratio of 70%. In 30 patients given vecuronium the mean time to reach this point (duration TOF70) was 66.7 min in the control group (no antagonist), 43.5 min in the group given neostigmine and 59.8 min in the group given edrophonium. The duration TOF70 was shorter in the neostigmine group than in the control (P less than 0.01) and edrophonium (P less than 0.01) groups. The duration TOF70 did not differ from control in the edrophonium group. In 29 patients given atracurium, the durations TOF70 were 66.4, 44.1 and 54.9 min in the control, neostigmine and edrophonium groups, respectively. The durations TOF70 in the neostigmine (P less than 0.01) and edrophonium (P less than 0.01), groups were shorter than control. The duration TOF70 of the neostigmine group was shorter than in the edrophonium group (P less than 0.01). These results show that profound neuromuscular blockade cannot be rapidly antagonized by either of these two agents, but if reversal is required under these circumstances, neostigmine would be the more effective drug.
