BACKGROUND: Postpartum depression (PPD) has a prevalence ranging from 3% to 30% and is associated with serious infant growth and developmental problems. Interventions directed at improving maternal mood have been unsuccessful in producing changes in observed face-to-face interactions between mother and infant. The Keys to Caregiving (KTC) is an intervention program that helps parents to understand and respond to infant behaviours, with a goal of increasing positive affective expressions in infants. In this pilot study, KTC was used with mothers suffering from mild to moderate PPD and their infants. METHODS: PPD was confirmed by scores on the Edinburgh Postnatal Depression Scale and the Beck Depression Inventory. Eleven dyads completed the study. KTC was carried out in 5 weekly group sessions, beginning at infant age of 3 months. Dyads were videotaped prior to and after KTC, using the Face-to-Face Still-Face paradigm, which assesses infants' responses during normal play and the effects of the Still-Face perturbation. The tapes were scored for infant facial emotion expressions. RESULTS: After intervention, infants displayed a marked increase in Interest and Joy when interacting face-to-face with their mothers, even though mothers' depression ratings did not change. LIMITATIONS: This pilot study is limited by lack of control dyads, however, it provides the foundation necessary for a full trial. CONCLUSIONS: This study suggests that intervention that focuses on what mothers do with their infants instead of how they feel can be effective in increasing infants' positive responsiveness and improving infant outcomes. Such interventions can be an essential component of treatment when mothers present with postpartum depression. 相似文献

Juvenile drug courts (JDCs) are a growing response to adolescent substance use, but better understanding of modifiable risk factors is needed to improve JDC outcomes. JDCs also serve dual public health and justice functions, heightening potential impact on co-occurring health factors like risky sex. However, mental health symptoms and peers’ activities may impede JDC effectiveness. In a unique longitudinal sample of 105 adolescents involved in JDCs, we find elevated internalizing symptoms and deviant peer behavior were each associated with increased substance use, with similar effects on risk for condomless sex. Findings inform intervention targets that could maximize JDC programming impact. 相似文献

Eleven abdominal computed tomographic (CT) examinations were performed in 10 patients with antibiotic-induced colitis. The clinical, endoscopic, and CT findings are presented. The most common CT findings were colonic dilatation and bowel wall thickening. However, small bowel dilatation was commonly seen. Intramural gas and ascites were less frequent findings. The diagnosis of antibiotic-induced colitis was rarely made before CT examination. Consequently, attentiveness to these CT abnormalities can expedite specific treatment. When these findings are noted on CT they represent the equivalent of toxic megacolon and administration of rectal contrast is contraindicated. 相似文献

OBJECTIVE: Mast cells are involved in allergic and inflammatory reactions. These cells are also increased in the bone marrow, skin, and other organs in systemic mastocytosis. Flavonoids are naturally occurring molecules with antioxidant, cytoprotective, and anti-inflammatory activities. Some flavonoids, like quercetin, inhibit the growth of certain malignant cells in culture. Quercetin also inhibits histamine release and induces accumulation of secretory granules in rat basophilic leukemia cells. METHOD: We investigated the effect of five flavonoids: flavone, kaempferol, morin, myricetin, and quercetin at 1, 10, and 100 microM on proliferation and secretory mediator content (beta-hexosaminidase, histamine, and tryptase) in human leukemic mast cells (HMC-1), the doubling time of which was about 2 d. RESULTS: Flavone and kaempferol at 100 microM inhibited cell proliferation over 80% on either day 3, 4, or 5 of culture. Quercetin showed this level of inhibition only on day 5, myricetin inhibited by 50% at days 3-5, whereas morin's inhibition was < 20%. All flavonoids (except morin) at 100 microm increased histamine and tryptase content, but not beta-hexosaminidase, equally at days 3 and 4 of culture quercetin also increased the development of secretory granules. CONCLUSION: These results indicate that certain flavonoids can inhibit HMC-1 proliferation, induce secretory granule development and the accumulation of mediators. 相似文献

Confirming partial small bowel obstruction is often a diagnostic challenge. In this case report, 4-mm solid radiopaque markers were used in 4 patients to show partial small bowel obstruction. Results of enteroclysis were normal in 2 of the 4 patients, and the markers were used to challenge suspected partial obstruction. The markers coalesced in the region of the partial obstruction, which was confirmed at surgery. Enteroclysis is the examination of choice in the diagnosis of partial small bowel obstruction. However, examinations with false- negative results can occur, particularly with adhesive and/or intermittent obstructions. The use of radiopaque markers in these cases proved an effective and useful method of establishing the diagnosis of partial small bowel obstruction, particularly in the 2 cases in which enteroclysis results were normal. Prospective studies are needed to establish the feasibility of this novel technique. (Gastroenterology 1996 Jun;110(6):1958-63) 相似文献

Objective: This prospective randomized trial compared the Angio‐Seal VIP? with Perclose Proglide? and to manual compression with respect to time to hemostasis and ambulation, patient satisfaction, and vascular complications following percutaneous coronary intervention (PCI). Background: The use of arterial closure devices for the reduction of vascular complications following PCI remains controversial. There have been no head to head trials comparing these most commonly used arterial closure devices following PCI. Methods: Two hundred patients undergoing PCI were randomized to manual compression, Perclose Proglide? or Angio‐Seal VIP?. Ambulation was allowed 3 hr after Perclose Proglide? or Angio‐Seal VIP? and 6 hr after compression. Results: There were 10 failures to deploy Perclose Proglide? and none for Angio‐Seal? (P < 0.01). Time to hemostasis was significantly shorter with Angio‐Seal VIP? compared with Perclose Proglide? (5.3 vs. 46.8 min, P < 0.01). Time to ambulation was shorter with Angio‐Seal VIP? than with Perclose Proglide? (261 vs. 334 min, P < 0.05) and the time to ambulation, as expected, was longest with compression (943 min, P < 0.01 vs. Angio‐Seal VIP? and Perclose Proglide?). Delay in ambulation was higher with Perclose Proglide? than with Angio‐Seal VIP? (18 vs. 9, P < 0.01). There was no significant difference in major vascular complications between groups. Compared with compression, patient discomfort was significantly improved with Angio‐Seal? (1.5 vs. 2.0, P < 0.01), but not with Perclose Proglide?. Conclusion: The Angio‐Seal VIP? device has a high rate of deployment success, which is significantly better than that of Perclose Proglide?. Angio‐Seal VIP? allows for earlier hemostasis and ambulation compared with both compression and Perclose Proglide? and is associated with greater patient satisfaction compared with compression. © 2008 Wiley‐Liss, Inc. 相似文献

PURPOSE: Several randomized trials have found that discharge planning improves outcomes for hospitalized patients. We do not know if adding a clinical nurse specialist (CNS) to physician teams in hospitals that already have discharge planning services makes a difference. METHODS: In 2 teaching hospitals, patients were randomly assigned to regular hospital care or care with a clinical nurse specialist. The clinical nurse specialist facilitated hospital care by retrieving preadmission information, arranging in-hospital consultations and investigations, organizing postdischarge follow-up visits, and checking up on patients postdischarge with a telephone call. In-hospital outcomes included mortality and length of stay. Postdischarge outcomes included time to readmission or death, patient satisfaction, and the risk of adverse event. Adverse events were poor outcomes due to medical care rather than the natural history of disease. RESULTS: A total of 620 sequential patients were randomized (CNS n = 307, control n = 313), of which 361 were followed after discharge from hospital (CNS n = 175, control n = 186). The groups were similar for the probability of in-hospital death (CNS 9.3% vs control 9.7%) or being discharged to the community (58.0% vs 60.0%). The groups did not differ for postdischarge outcomes including readmission or death (21.6% vs 15.6%; P = 0.16) or risk of adverse event (23.6% vs 22.8%). Mean [SD] patient ratings of overall quality of care on a scale of 10 was higher in the clinical nurse specialist group (8.2 [2.2] vs 7.6 [2.4]; P = 0.052). CONCLUSION: The addition of a clinical nurse specialist to a medical team improved patient satisfaction but did not impact hospital efficiency or patient safety. 相似文献

The theory that chronic alcoholism produces a right hemisphere deficit has generally been tested using visuospatial tasks. The present report tested the theory using three tasks that tap functions, other than visuospatial abilities, which have been failed by patients with right hemisphere damage. The first task assesses the ability to draw a correct inference by integrating information from two unrelated sentences. The second taps the patient's capacity to appreciate humor. The third requires the patient to interpret the emotion displayed in a face. On all three tasks, the pattern of responses of chronic alcoholics differed from that of patients with right hemisphere damage. Thus, the right hemisphere deficit theory fails to gain support from this investigation. On the other hand, the chronic alcoholics' performance was impaired relative to contemporary controls on the first two tasks, although not on the last. On the first two tasks, alcoholics' impairment approximated, and in one instance exceeded, that seen in normal elderly controls. Thus, a premature aging hypothesis received modest support from this study. 相似文献
