Relationships between infant crying, birth complications, and maternal variables

The aim of the study is to identify factors influencing infants' crying behaviour (total crying duration, length of crying bouts, and frequency of crying). The searching for variables explaining inter-individual differences requires a sufficient stability of the cry parameters at least over short time intervals. Thus, a second aim is to assess the intra-individual stability of the crying behaviour in an age range from 3 to 12 months. Sixty-two mother-child dyads participated in the study. The results show substantial stabilities of the crying behaviour of infants between 3 and 12 months of age. This is related to the amount of crying as well as to the pattern of crying shown by the children over a 24 h interval. The typical cry pattern is characterized by peaks at 12.00 h and early in the evening, although there are large individual differences between the children with regard to cry durations at each hour of the day. Regarding the cry durations at 3 months of age, birth complications and the perceived emotional atmosphere in the mothers' family of origin are the major contributing factors.     

Grandmaternal and maternal ethnotheories about early child care.

Parenting ethnotheories represent an organized set of ideas about parents, children, and development that are shared by members of cultural groups. Because these ideas and beliefs reflect cultural models and serve as representational frameworks for parenting strategies, they need to change with historical time. To analyze these changes, the authors interviewed mothers and grandmothers of 3-month-old infants in 4 different cultural environments--urban German middle-class families (41 mothers, 22 grandmothers), urban Indian middleclass families (36 mothers, 12 grandmothers), rural Cameroonian Nso families (29 mothers, 20 grandmothers), and urban Cameroonian Nso families (28 mothers, 12 grandmothers)--in regard to their ideas about infant care. The interviews were analyzed according to content and discourse style. The results reveal that there is not only transmission of parental beliefs from one generation to the next but also variation in adaptation to changing environments. Although the global trend toward more independent cultural models of parenting is confirmed, the magnitude of change varies across the different cultural environments.

Maternal learned helplessness and physiologic response to infant crying.

Exposed 49 mothers of 3–4 mo old infants to varying degrees of control over the termination of a tape of infant crying. Each S received 1 of 3 instrumental pretreatments: (a) escape—4 buttonpresses terminated the infant cry, (b) inescape—buttonpress was unrelated to cry termination, and (c) control—mothers passively listened to the cry. Following pretreatment, each S was given an instrumental shuttlebox task consisting of a solvable task with an alternation response that controlled cry termination. Cardiac responses were monitored throughout the session. Ss pretreated with inescapable infant crying showed debilitated performance on the 2nd task. Failure to escape, number of trials to escape criterion, and latency of response to the cry were all greater for the inescape group. In addition, only Ss with prior experience controlling the cry showed cardiac deceleration, an index of attentional processing, during a 10-sec anticipatory period preceding the cry episode of the solvable instrumental task. These cardiac data provide evidence that the important behavioral differences may in part be attributable to differential processing of cues signaling the onset of crying.

The relationship between maternal use of heroin and methadone and infant birth weight

AIMS/DESIGN: Reduction in mean birth weight and increased incidence of low birth weight are both associated with exposure to illicit heroin in pregnancy. Many studies examining neonatal outcomes in pregnant heroin users treated with methadone report improvements in birth weight. As a consequence, methadone treatment has become the 'gold standard' for the management of the pregnant heroin user. However, not all studies report significant birth weight increases associated with methadone. We undertook a number of meta-analyses on reduction in mean birth weight and incidence of low birth weight to estimate more precisely the effect of illicit heroin and methadone. FINDINGS: Results showed mean reduction in birth weight associated with heroin use: 489 g (95% CI 284-693 g), compared with methadone: 279 g (229-328 g). Similarly, the pooled relative risk estimate for low birth weight for maternal heroin use was 4.61 (95% CI 2.78-7.65), compared with 1.36 (0.83-2.22) for methadone. Analysis of data on combined heroin and methadone use produced a pooled mean reduction in birth weight of 557 g (403-710 g), with a pooled relative risk estimate for low birth weight of 3.28 (2.47-4.39). Pooling 'any' methadone data, regardless of heroin use, produced an estimated reduction in birth weight of 395 g (311-478 g) and a relative risk estimate for low birth weight of 1.90 (1.29-2.81). Combining all data in an 'any' opiate use analysis also produced a mean reduction in birth weight of 483 g (386-583 g) and a relative risk estimate for low birth weight of 3.81 (2.57-5.65). CONCLUSIONS: The current findings suggest that heroin use while receiving methadone may counteract the birth weight advantage gained from methadone alone. Whether this is due to fetal exposure to heroin plus methadone, to reduced antenatal care, other behavioural and environmental factors associated with concurrent use of heroin and methadone or a combination of these is unclear. Nevertheless, these results challenge the current belief that the pregnant user is always better off receiving methadone than not, and suggests that methadone may not be the appropriate treatment for the pregnant women who continue to use illicit heroin.     

Diagnosis of maternal and infant health in Palestine

A new immunogenic outer membrane protein, Omp-28 (MW 28,000 and pI 4.6), was isolated from smooth Salmonella typhi cells by the use of an extracting medium containing 6 M urea, 1% deoxycholate and 5 mM EDTA. The purification of Omp-28 was performed by gel filtration and fast ion exchange chromatography. This protein showed to be the prevalent component isolated by the latter methodology. Omp-28 is formed by three identical subunits (MW 9,000), not linked by disulfide bonds. The partial N-terminal amino acid sequence of Omp-28 presented great homology with part of the sequence of an Escherichia coli protein found in a precursor whose sequence was predicted by c-DNA. ELISA and Western blotting identified Omp-28 as the major antigenic protein present in the outer membrane protein fraction, isolated by gel filtration. Antibodies against Omp-28 were detected by ELISA in 43% of 28 sera from typhoid fever convalescent patients. The antisera from mice immunized with Omp-28 and the highest positive typhoid fever convalescent serum gave a positive bactericidal test, killing 50% of Salmonella typhi cells in serum dilutions of 1/80 and 1/320, respectively. These results indicate the immunogenic importance of Omp-28 isolated from Salmonella typhi outer membrane and strongly suggest it should be used in further studies of animal protection against the disease caused by this pathogenic bacteria.     

Maternal and infant care: comparisons between Western Europe and the United States

A series of studies between 1986 and 1990 gathered data on maternal and infant care in ten Western European countries with lower infant mortality rates than the United States and compared the findings both within the European countries and in aggregate with the United States. Results from these studies reveal great variation among the study countries in how perinatal care is financed, staffed by professional and nonprofessional health workers, and provided by public clinics or private offices, and in the number of and locale of the recommended number of prenatal visits. Invariably consistent among the study countries is the nearly complete enrollment of childbearing women in early and continuous prenatal care, and the strong linkage of that care to a generous spectrum of social supports and financial benefits. None of the benefits generally pertains in the United States. The relevance of these observations for the United States suggests that current policies intended to lower economic barriers to a highly medicalized version of maternity care may yield disappointing results unless the perinatal sequence is linked to a more generous set of maternity-related social supports and financial benefits than is now contemplated.     

Relations between early child care and schooling.

The purpose of this article is to examine relations between aspects of early child care (age entered, full- or part-time structure, and number of child-care arrangements and their quality) and school adjustment. The early child-care experiences of 87 children who entered a laboratory elementary school at 3 years, 9 months of age were documented, and their first-grade adjustment was assessed 3 years after school entrance. Although single-parent families and families in which the mother was employed used more child care and enrolled their children at earlier ages, maternal education was more closely associated with children's school adjustment than was maternal employment or marital status. After family characteristics were accounted for, academic progress, school skills, and few behavioral problems were predicted by high-quality, stable child care. The structure of the early child care (full- or part-time) was not associated with school adjustment. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Nosocomial gastroenteritis in two infant wards over 26 months

We retrospectively reviewed 209 cases of nosocomial diarrhea in two infant wards at St G?ran's Children's Hospital. They occurred from April 1987 to May 1989, when 3105 patients spent 26,355 hospital days. The hospital is a 250-bed tertiary center with university affiliation. Fourteen percent of patients at risk developed nosocomial diarrhea, and the relative attack rate was 1.1 episodes per 100 hospital days. A probable viral etiology was found in 47% of patients. Rotavirus was most frequent and occurred during the community rotavirus seasons. Also small, round, structured viruses were common, and two outbreaks of astrovirus gastroenteritis occurred. Failure to detect a virus was particularly common among infants younger than 4 months. However, a seasonal distribution and peaks concordant with defined clusters in older patients, suggest also that some of these detection-negative cases may have a viral etiology.     

Adults' perceptions of experimental modifications of durations of pauses and expiratory sounds in infant crying.

Durations of all pauses and expiratory sounds in a 10-sec bout of infant crying were digitally increased and decreased by 50% to create cries that varied in the duration of pauses and expiratory sounds. Ratings by 40 men and women showed a general monotonic effect of pause duration so that cries with increasingly shorter pauses were perceived to be more arousing, informative, and aversive. The monotonic effect for pause duration was enhanced in an interaction with expiration duration for perceptions of urgency. Results provide the 1st known experimental evidence of how variations in the temporal structure of infant crying differentially affect adults' perceptions and support views of the cry of the young infant as a graded signal.

Links between psychology and religion.

Psychology has been related to religion in 2 important ways: first in taking the data of religious life as relevant material for empirical, and later in terms of the emergence of clinical psychology and an interest in psychotherapy. "The unity of aim shown by religion and psychology is twofold: concern for the individual person and a value orientation relative to his true well-being… . What this paper is suggesting is that psychotherapy, by virtue of the obvious ethical implications involved in its 'caring' for or 'treating' persons and because of its unavoidable espousal of some view of man and some value orientation as to his true well-being, has brought psychology and religion into a contiguity and interlacing of work where it is no longer possible to distinguish neatly the psychologist from his religious colleague." Psychology and religion "are linked arm in arm in the depths and in the implications of psychotherapeutic practice." (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Chronicity of maternal depressive symptoms, maternal sensitivity, and child functioning at 36 months.

Women (N?=?1,215) and their infants were followed from birth, and maternal reports of depressive symptoms were obtained at 1, 6, 15, 24, and 36 months. Women who never reported symptoms of depression were compared with those who reported symptoms sometimes or chronically. Women with chronic symptoms of depression were the least sensitive when observed playing with their children from infancy through 36 months. Children whose mothers reported feeling depressed performed more poorly on measures of cognitive-linguistic functioning and were rated as less cooperative and more problematic at 36 months. Depression-group differences in school readiness and verbal comprehension were accounted for by maternal sensitivity. Depression-group differences in expressive language and ratings of cooperation were moderated by maternal sensitivity; maternal sensitivity predicted better outcomes more noticeably among children whose mothers reported feeling depressed.

Links between temperamental dimensions and brain monoamines in the rat.

In 27 female Wistar rats, the authors obtained composite scores on harm avoidance and novelty seeking, as well as 57 measures of monoamines and metabolites from 10 different brain regions. A multivariate regression method was used to discover associations between individual differences in temperament and neurochemistry. Harm-avoidant subjects had low levels of striatal dopamine and high levels of cortical norepinephrine and amygdaloid 5-hydroxyindoleacetic acid. High novelty-seeking scores were linked to low levels of brainstem serotonin and dopamine and to low levels of 5-hydroxyindoleacetic acid in amygdala and accumbens. Moreover, rats scoring high on novelty seeking had higher-than-average levels of norepinephrine in the thalamus and amygdala and of serotonin in the amygdala.

The persistent OP. Can maternal position rotate the baby?

The paper presents the authors' experience in introducing a new system for active detection of patients with tuberculosis by using the database (a computer-register of individuals aged above 15 years and a programme for rapid evaluatin of the individual risk for tuberculosis, which reduces the scope of fluorographic and other examinations of the population for tuberculosis.     

Persistent crying in early infancy: a non-trivial condition of risk for the developing mother-infant relationship

Infants between 1 and 6 months of age (mean age 3.6 months) who were referred to the Munich Interdisciplinary Research and Intervention Programme because of persistent crying and their mothers were examined and compared with an age-matched community-based control sample with no current cry problem. Three groups, referred extreme criers, referred moderate criers, and controls, were compared with regard to measures of psychosocial and organic risks, the mothers' perception of her own psychological state and infant temperament, the quality of mother-infant relationship, and intuitive parenting in mother-infant face-to-face interactions. In comparison with general-community samples of infants with persistent crying, the present clinical sample represents a biased group with particularly high levels of infant distress for long periods of time, with problems of sleep-wake organization, neuromotor immaturity, and difficult temperament. Moreover, extreme crying was associated with a cumulation of organic and psychosocial risks, including high rates of prenatal stress and anxiety, maternal psychopathology and partnership conflicts. Mothers in both referred groups scored similarly low on feelings of self-efficacy, and high on depression, anxiety, exhaustion, anger, adverse childhood memories, and marital distress. Mother-infant relationships were more often distressed or disturbed among referred dyads than among controls, and 40% as compared with 19% showed dysregulatory patterns of interactional failures in face-to-face contexts. The findings suggest that factors related to parental care did not cause persistent crying, but functioned as maintaining or exacerbating factors. Dynamic interactions between persistent crying, difficult temperament, and parenting factors which compromise maternal resources and intuitive parenting may put such families at long-term risk for both relationship and behaviour problems.     

Domestic violence, maternal parenting, maternal mental health, and infant externalizing behavior.

This study examined whether maternal functioning mediated the relationship between domestic violence (DV) and infant externalizing behavior. Participants were 203 mother-infant dyads. Support was found for a partially mediated model in which maternal functioning mediated the relationship between current DV and infant externalizing behaviors. Past DV was directly associated with infants' externalizing behavior. Results suggest the need for early intervention and prevention efforts for families living with DV.

Effect of maternal cholestasis on biliary lipid and bile acid secretion in the infant rat

Monoclonal antibodies specific for haemocyte sub-populations in the mussel, Mytilus edulis, were raised by use of separated basophilic and eosinophilic cell types as antigens. The antibodies could be broadly divided into 3 groups, reactive with sub-populations of (1) basophilic granular haemocytes, (2) basophilic granular and hyaline cells and (3) eosinophilic granular cells. Non-selective antibodies staining all haemocytes were also generated. The antibodies bound to epitopes of differing molecular masses and, at the ultrastructural level, reacted principally with the granules of the haemocyte sub-populations. The antibodies were used to investigate haemocyte function and ontogeny and to test reactivity with haemocytes from mussels subject to varying degrees of pollution stress. Five antibodies showed reactivity with cells from the trochophore and veliger larvae of M. edulis, indicating that epitopes on adult mussel hae-mocytes are also present at much earlier stages in the life history. Reactivity with the larval stages was most prevalent with non-selective antibodies and those selective for basophilic haemocytes. When mussels from different sites were examined, both immunocytochemistry and ELISA showed reduced expression of a 140 kDa epitope in the haemocytes of mussels subject to greater contaminant loads. These results show that the monoclonal antibodies of the present study are valuable both in tracing immune-cell development and in detecting molecular changes under conditions of stress.     

Determinants of infant responses to vaccines in presence of maternal antibodies

Presence of maternally-derived antibodies at time of immunization is known to often interfere with active infant immunization, although with variable degrees of clinical significance. In order to progressively decipher the rules that form the basis for these inhibitory effects on infant vaccine responses, two antigens (measles, tetanus) and various antigen presentation systems were evaluated in murine early life immunization models either in absence or presence of maternal antibodies. Both conventional (proteins, conjugate vaccines) and new (live viral vectors, DNA plasmids) antigen presentation systems were found to be similarly susceptible to the inhibitory influence of maternal antibodies. Factors emerging as crucial determinants of maternal antibody-mediated effects on responses to both live and non-live vaccines include (i) the level of maternal antibodies present at immunization, (ii) the use of distinct vaccines in mothers and pups and (iii) their distinct influence on B cell and T cell vaccine responses.     

Frightening maternal behavior linking unresolved loss and disorganized infant attachment.

Main and Hesse's (1990) model in which frightening (threatening, frightened, or dissociated) parental behavior explains why infants of parents with unresolved loss develop disorganized attachment relationships was tested. Unresolved loss using the Adult Attachment Interview in a nonclinical middle-class sample of 85 mothers who had experienced the loss of someone important was assessed. Disorganized attachment was examined in the Strange Situation. Parental behavior was recorded during 2 2-hr home visits. The model applied to mothers with currently insecure attachment representations. Secure mothers with unresolved loss displayed less frightening behavior than other mothers, and unresolved loss in secure mothers did not predict disorganized attachment of their infants. Frightening behavior predicted infant disorganized attachment irrespective of maternal security. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
