A total of 571 cases were selected through the Metropolitan Detroit Cancer Surveillance System and interviewed three (n = 463) and 12 (n = 422) months after diagnosis about their needs in transportation, housekeeping, meal preparation, and grocery shopping. A total of 647 controls aged 55 to 84 were selected through random-digit dialing and interviewed twice over the same period (n = 539 and 478). At three months, cases aged 55 to 74 report greater difficulty and less independence than controls in completing instrumental tasks. Little difference is shown between cases and controls aged 75 to 84. Nine months later, functional status is similar for cases and controls aged 55 to 64. In contrast, cases aged 65 to 74 continue to be less independent than controls of the same age.

The authors investigated the relation between airway complications in children receiving general anesthesia and the passive inhalation of tobacco smoke. Methods Six hundred two children scheduled to receive general anesthesia were enrolled in this prospective study. The anesthesiologist and the recovery room nurse, unaware of the smoke exposure history, recorded the occurrence of airway complications. A history of passive smoking was assessed by measuring the urinary concentration of the major nicotine metabolite cotinine and by questionnaire. Results Airway complications occurred in 42% of the patients with urinary concentrations of cotinine > or =40 ng/ml, in 33% of the patients with concentrations of cotinine between 10.0 and 39.9 ng/ml, and in 24% of the patients with concentrations of cotinine < 10 ng/ml (P = 0.01 for the trend among the three groups). The gender of the child (P = 0.001) and the educational level of the child's mother (P = 0.0008) significantly modified the effect of the concentration of cotinine on the incidence of adverse respiratory events. Conclusions There is a strong association between passive inhalation of tobacco smoke and airway complications in children receiving general anesthesia. The relationship is greatest for girls and for those whose mothers have a lower level of education. Passive smoking should be regarded as a risk factor in children undergoing general anesthesia.

The process of interaction across time in a large low-risk community sample at infant age 4 months was examined. Split-screen videotape was coded on a 1-s time base for communication modalities of attention, affect, orientation, touch, and composite facial-visual engagement. Time-series approaches generated self- and interactive contingency estimates in each modality. Evidence supporting the following principles was obtained: (a) Significant moment-to-moment predictability within each partner (self-contingency) and between the partners (interactive contingency) characterizes mother-infant communication. (b) Interactive contingency is organized by a bidirectional, but asymmetrical, process: Maternal contingent coordination with infant is higher than infant contingent coordination with mother. (c) Self-contin...

Attention, affect, spatial orientation, and touch were coded from split-screen videotape on a 1-s time base. Self-and interactive contingency were assessed by timeseries methods. Because anxiety symptoms signal emotional dysregulation, we expected to find atypical patterns of mother-infant interactive contingencies, and of degree of stability/lability within an individual's own rhythms of behavior (self-contingencies). Consistent with our optimum midrange model, maternal anxiety-related symptoms biased the interaction toward interactive contingencies that were both heightened (vigilant) in some modalities and lowered (withdrawn) in others; both may be efforts to adapt to stress. Infant self-contingency was lowered ("destabilized") with maternal anxiety symptoms; however, maternal self-contingency was both lowered in some modalities and heightened (overly stable) in others. Interactive contingency patterns were characterized by intermodal discrepancies, confusing forms of communication. For example, mothers vigilantly monitored infants visually, but withdrew from contingently coordinating with infants emotionally, as if mothers were "looking through" them. This picture fits descriptions of mothers with anxiety symptoms as overaroused/fearful, leading to vigilance, but dealing with their fear through emotional distancing. Infants heightened facial affect coordination (vigilance), but dampened vocal affect coordination (withdrawal), with mother's face-a pattern of conflict. The maternal and infant patterns together generated a mutual ambivalence.

Self-and interactive contingency (auto-and lagged cross-correlation, respectively) were assessed by multilevel time-series analysis. Infant and mother gaze, facial and vocal affect, touch, and spatial orientation behaviors were coded second-by-second from splitscreen videotape, and a multimodal measure of facial-visual "engagement" was constructed, generating nine modality pairings. With higher CES-D, the self-contingency of both partners was lowered in most modalities. With higher CES-D, interactive contingency values were both heightened (in some modalities) and lowered (in others), varying by partner. These results are consistent with an optimal midrange model. With higher CES-D, interactive contingency showed the following patterns: (a) Mothers and their infants had a reciprocal orientational sensitivity; (b) mothers and infants manifested a reciprocal intermodal discordance in attention versus affect coordination, lowering gaze coordination, but heightening affective coordination; (c) infants heightened, but mothers lowered, touch coordination with partner touch-an "infant approach-mother withdraw" touch pattern. Nonlinear analyses indicated that altered self-and interactive contingency were similar at both the low ("denial") as well as the high ("endorsement") poles of depressive symptoms, in half the findings. These complex, multimodal findings define different aspects of communication disturbance, with relevance for therapeutic intervention.

Infant and mother face, gaze, touch, and vocal quality were coded second by second from split-screen videotape. Self-and interactive contingencies were defined as auto-and lagged cross-correlation, respectively, using multilevel time-series models. Statistical significance was defined as p Ͻ .05. Regarding selfcontingency, (a) more self-critical mothers showed primarily lowered self-contingency, whereas their infants showed both lowered and heightened, and (b) infants of more dependent mothers showed primarily lowered self-contingency, whereas findings were absent in mothers. Regarding interactive contingency, (a) more self-critical mothers showed lowered attention and emotion contingencies but heightened contingent touch coordination with infant touch, and (b) more dependent mothers and their infants showed heightened facial/vocal interactive contingencies. Thus, maternal self-criticism and dependency have different effects on mother-infant communication.
