Oliván G 《Child abuse & neglect》2003,27(1):103-108
OBJECTIVE: To assess the catch-up growth of long-term physically neglected and emotionally abused preschool male children who have entered foster residential care and remained 1 year after initial placement. METHOD: Longitudinal study over a 7-year period (1994-2001). So that a child was eligible for the study, three selection criteria were included: (1) aged between 24 and 48 months at the time of entry into residential facility, (2) having suffered both long-term (more than 6 months) physically neglected and emotionally abused, and (3) having stayed in foster care for 1 year after initial placement. Weight, height, and head circumference were established upon entry and re-assessed 1 year after initial placement, calculating the annual growth velocity. Results were compared with normal regional longitudinal standards of reference (Z score). Student's t test was used to assess statistically significant differences. RESULTS: During the study period, 87 children aged between 24 and 48 months (54 male/33 female) were admitted to residential facility after having suffered both long-term physical neglect and emotional abuse. Nevertheless, only 20 children (23% of the total admissions) met the third selection criteria (having remained 1 year after initial placement). Of these children, all were males and at placement they were between the ages of 30 and 42 months, with an average age of 36 months (1.9 SD). At placement, the analyzed parameters were below the normal standards, showing a statistically significant difference for height (Z score = -1.29; p = .008) and weight (Z score = -.75; p = .038). The annual growth velocity for all parameters was above the normal standards showing a statistically significant difference for height (Z score = +1.43; p = .009). One year after initial placement, the significant differences for height (Z score = -.68; p = .102) and weight (Z score = -.31; p = .435) with respect to the normal standards disappeared, though still remained below, showing a significant catch-up growth for height (improvement height Z = +.61 SD). CONCLUSIONS: At placement, the both long-term physically neglected and emotionally abused preschool age male children showed a mild form of chronic malnutrition with growth failure. Growth failure was reversible after the first year of stay, which demonstrates that this delay in growth was secondary to nutritional and psychosocial factors. Placement in foster residential care was beneficial for the catch-up growth of these patients. 相似文献

Objective
In postmenopausal women, an increased leptin concentration and reduced levels of ghrelin and adiponectin were observed. The aim of this study was to evaluate the concentrations of the active form of ghrelin, total ghrelin, leptin receptor, lipoprotein(a) (Lp(a)), and plasminogen activator inhibitor type 1 (PAI-1) in postmenopausal women who received oral or transdermal menopausal hormonal therapy (MHT). 相似文献993.

This study compared reactive agility between higher-standard (n = 14) and lower-standard (n = 14) Australian footballers using a reactive agility test incorporating a life-size video image of another player changing direction, including and excluding a feint. Mean agility time in the feint trials was 34% (509 ± 243 ms; p < 0.001; effect size 3.06) longer than non-feint trials. In higher-standard players, agility time was shorter than for lower-standard players in both feint (114 ± 140 ms; p = 0.18; effect size 0.52; likely beneficial) and non-feint (32 ± 44 ms; p = 0.22; effect size 0.47; possibly beneficial) trials. Additionally, the inclusion of a feint resulted in movement time increasing over three times more in the lower-standard group (197 ± 91 ms; p = 0.001; effect size 1.07; almost certainly detrimental) than the higher-standard group (62 ± 86 ms; p = 0.23; effect size 0.66; likely detrimental). There were weak correlations between the feint and non-feint trials (r = -0.13-0.14; p > 0.05), suggesting that reactive agility involving a feint is a unique skill. Also, higher-standard players are more agile than their lower-standard peers, whose movement speed deteriorates more as task complexity increases with the inclusion of a feint. These results support the need for specific training in multi-turn reactive agility tasks. 相似文献

A semi-analytical Monte Carlo (SMC) simulation was developed to simulate the propagation of laser-induced fluo- rescence (LIF) in an optically participating spray, which simultaneously exhibits spectrally dependent emission, anisotropic scattering, absorption, and re-emission. The SMC simulation is described and then applied to an experimental configuration of a cloud of polydisperse droplets composed of water and sulforhodamine B dye. In the SMC simulation, the collected LIF flux on the remote receptor element is calculated as the global contribution from the emissive source, single, twice, … and nth collision events in any sequence. The effects on the fluorescence photons propagation of spray parameters like the dye concentration, droplets concentration, and droplets size are examined. Three spectral bands representing different optical properties are chosen to analyze the interference of absorption, scattering and re-emission on the detected LIF flux. The obtained spectral LIF flux distribution on the receptor demonstrates a “red shift” phenomenon. 相似文献

OBJECTIVE: This study of bulimic women examined the relationship between the severity of four forms of reported child abuse (emotional abuse, neglect, physical abuse, sexual abuse) and bulimic pathology. ln addition, it investigated the relationship of abuse with dissociation and core beliefs. METHOD: A sample of 23 women with bulimic disorders completed standardized self-report measures of child abuse, dissociation, core beliefs, and bulimic symptomatology. They also completed diary records of bulimic behaviors. RESULTS: No dimensional relationship was found between any form of child abuse and bulimic pathology. However, within this group of bulimics, neglect and sexual abuse were correlated with dissociation. In addition, a subset of core beliefs was associated with child abuse, with different cognitive profiles associated with each form of trauma. CONCLUSIONS: The findings need to be interpreted with caution because of the small, heterogeneous sample involved. Further research involving larger, homogenous samples is needed to investigate the generalizability of these findings, in order to determine if particular abusive experiences and core beliefs need to be addressed therapeutically in such cases. In addition, future research should consider the relationships between abuse, core beliefs and other impulsive behaviors. 相似文献

Dietary generalists often treat new foods with caution and may rely on social cues to identify new foods that are safe to eat. However, not all generalists show the same degree of caution, nor do they all rely on social cues to the same extent. The cue reliability approach (CRA) attempts to account for this variation by quantifying the costs and benefits of sampling a new food for the first time. The experiments reported here tested predictions of the CRA, and the results suggested that rats eat more new food when asocial cues predict that new foods will prove more profitable than familiar foods. The experimental results also suggested that rats are more likely to seek out social cues when asocial cues are unreliable. 相似文献
