Global rates of caesarean section (CS) rates have increased rapidly in recent years. This is a growing public health concern as it has been proposed that CS may impact cognitive outcomes in childhood. However, the evidence for this association is limited and inconsistent. Therefore, the aim of this study was to investigate the relationship between obstetric mode of delivery and longitudinal cognitive outcomes in childhood.
Methods
We examined this question using data from a longitudinal cohort study of 8845 participants from the Millennium Cohort Study, a nationally representative UK cohort, who completed a range of verbal and visual-spatial cognitive assessments at ages 3, 5, 7 and 11 years.
Results
We found a statistically significant association between planned CS and visual-spatial cognitive delay in the pattern construction assessment at age 5 (OR 1.31, 95% CI 0.99–1.72) and age 7 (OR 1.42, 95% CI 1.12–1.81). Additionally planned CS was also associated with increased odds of “early childhood delay” (OR 1.70, 95% CI 1.15–2.50) and borderline increased odds of “persistent delay” (OR 1.37, 95% CI 0.99–1.89) in visual-spatial cognitive tests. Mode of delivery was not associated with verbal ability or with patterns of delay at any age point in verbal cognitive tests.
Conclusion
We have reported a small association between planned CS and visual-spatial cognitive delay in childhood. However, while this result should be interpreted with caution, it highlights the need to further explore this potential relationship and the causal basis of such an association.
ObjectiveTo examine the relationship between depression and/or anxiety and any psychiatric diagnosis and readmission after childbirth.DesignCross-sectional analysis of administrative data from patient discharge records.SettingUrban academic medical center in the northeastern United States.ParticipantsWomen admitted for childbirth (N = 17,905).MethodsDifferences among participants with and without depression and/or anxiety present on admission were compared using t tests and chi-square tests. Risk-adjusted logistic regression models were used to examine the effects of depression and/or anxiety and any psychiatric diagnosis on 7-, 30-, 60-, 90-, and 180-day readmissions after childbirth.ResultsSignificant differences were noted between participants with (n = 1,169) and without (n = 16,736) depression and/or anxiety. Participants with these diagnoses had a higher mean age and a longer mean length of stay during hospitalization for childbirth. A greater proportion of these participants were White, were single, had cesarean births, and were discharged with home health services. The presence of depression and/or anxiety was not significantly associated with readmission. The effect of having any psychiatric diagnosis was significantly associated with a greater risk of readmission at 7 (odds ratio [OR] = 1.51, p = .100), 30 (OR = 1.45, p = .030), 60 (OR = 1.45, p = .026), 90 (OR = 1.56, p = .004), and 180 days (OR =1.74, p < .001) following discharge after childbirth.ConclusionIn this sample, women with a psychiatric diagnosis, but not depression and/or anxiety alone, were at increased risk for readmission after childbirth. 相似文献
Mental health resources are designed to facilitate recovery for adults with psychiatric disabilities. Two participants of an autovideography intervention described systems barriers to recovery. Researchers employed narrative analysis, guided by the capabilities approach, to evaluate how participants storied their experiences. Participants made meaning from encounters with barriers in ways that oppose the spirit and advancement of recovery while engendering adaptive preferences. Findings indicate that inadequate resources attenuate wellbeing by increasing barriers that actively oppose recovery, and positive reframing of unaccommodating environments reinforces adaptive preferences and incapacity. Adequate resources are essential for successful recovery transformation within the mental health system. 相似文献
Overcoming specific fears and subsequent anxiety can be greatly enhanced by the presence of familiar social partners, but the neural circuitry that controls this phenomenon remains unclear. To overcome this, the social interaction (SI) habituation test was developed in this lab to systematically investigate the effects of social familiarity on anxiety-like behavior in rats. Here, we show that social familiarity selectively reduced anxiety-like behaviors induced by an ethological anxiogenic stimulus. The anxiolytic effect of social familiarity could be elicited over multiple training sessions and was specific to both the presence of the anxiogenic stimulus and the familiar social partner. In addition, socially familiar conspecifics served as a safety signal, as anxiety-like responses returned in the absence of the familiar partner. The expression of the social familiarity-induced anxiolysis (SFiA) appears dependent on the prefrontal cortex (PFC), an area associated with cortical regulation of fear and anxiety behaviors. Inhibition of the PFC, with bilateral injections of the GABAA agonist muscimol, selectively blocked the expression of SFiA while having no effect on SI with a novel partner. Finally, the effect of D-cycloserine, a cognitive enhancer that clinically enhances behavioral treatments for anxiety, was investigated with SFiA. D-cycloserine, when paired with familiarity training sessions, selectively enhanced the rate at which SFiA was acquired. Collectively, these outcomes suggest that the PFC has a pivotal role in SFiA, a complex behavior involving the integration of social cues of familiarity with contextual and emotional information to regulate anxiety-like behavior. 相似文献
We conducted an epidemiological study of the cumulative frequency and incidence of Lyme disease in a summer community on Fire Island, New York, an area endemic for the disease. Fifteen (7.5%) of 200 persons studied in the community in 1982 reported a history of Lyme disease. An indirect immunofluorescent antibody assay showed that seventeen (9.7%) of 176 persons had serological evidence of exposure to the Lyme spirochete, including six of the 15 persons with a history of Lyme disease. Seven (0.7%-1.2%) of 600-1,000 persons in the community developed clinical symptoms and serological evidence of Lyme disease during the summer season, including two (1%) of the 200 persons in the study group. Four (3.1%) of 129 persons who had sera collected before and after the summer season demonstrated fourfold or greater rises in IgG antibody titers to the Lyme spirochete, including 2 (1.6%) persons without symptoms of Lyme disease. We conclude that the incidence of Lyme disease can be appreciably higher in endemic areas than previously recognized and that subclinical or inapparent seroconversion may occur after infection. 相似文献
Degree of pupil dilation has been shown to be a valid and reliable measure of cognitive load, but the effect of aural versus visual task presentation on pupil dilation is unknown. To evaluate effects of presentation mode, pupil dilation was measured in three tasks spanning a range of cognitive activities: mental multiplication, digit sequence recall, and vigilance. Stimuli were presented both aurally and visually, controlling for all known visual influences on pupil diameter. The patterns of dilation were similar for both aural and visual presentation for all three tasks, but the magnitudes of pupil response were greater for aural presentation. Accuracy was higher for visual presentation for mental arithmetic and digit recall. The findings can be accounted for in terms of dual codes in working memory and suggest that cognitive load is lower for visual than for aural presentation. 相似文献
OBJECTIVE: To assess the efficacy and safety of 100 mg daily anakinra (Kineret), a recombinant form of the naturally occurring interleukin 1 receptor antagonist, plus methotrexate (MTX) in reducing the signs and symptoms of rheumatoid arthritis (RA). METHODS: Patients with active RA (n = 506) despite current treatment with MTX were enrolled in this multicentre, double blind, randomised, placebo controlled study. Patients received subcutaneous injections of anakinra 100 mg/day or placebo. They were assessed monthly for 6 months for improvement in signs and symptoms of RA and for adverse events. The primary efficacy measure was the percentage of patients attaining ACR20 response at week 24. RESULTS: Significantly greater proportions of patients treated with anakinra compared with placebo achieved ACR20 (38% v 22%; p<0.001), ACR50 (17% v 8%; p<0.01), and ACR70 (6% v 2%; p<0.05) responses. The response to anakinra was rapid; the proportion of patients with an ACR20 response at the first study assessment (4 weeks) was twice as high with anakinra as with placebo (p<0.005). Clinically meaningful and statistically significant responses were also seen in individual components of the ACR response (for example, Health Assessment Questionnaire, pain, C reactive protein levels, and erythrocyte sedimentation rate). Anakinra was well tolerated, with a safety profile, similar to that of placebo with one exception: mild to moderate injection site reactions were more common with anakinra than with placebo (65% v 24%). CONCLUSIONS: This study confirms previous observations from a dose-ranging study showing that anakinra, in combination with MTX, is an effective and safe treatment for patients with RA who have inadequate responses to MTX alone. 相似文献
Recently, an 8-item short-form version of the Chronic Pain Acceptance Questionnaire (CPAQ-8) was developed predominantly in an internet sample. Further investigation of the factor structure in a multidisciplinary pain clinic sample is required. Investigation of the concurrent validity of the CPAQ-8 after accounting for the effects of variables commonly measured in the pain clinic setting is also necessary.
Purpose
This study examines the factor structure and concurrent validity of the CPAQ-8 in a sample of treatment-seeking patients who attended a multidisciplinary pain clinic.
Methods
Participants were 334 patients who attended an Australian multidisciplinary pain service. Participants completed the CPAQ, a demographic questionnaire, and measures of patient adjustment and functioning.
Results
Confirmatory factor analysis identified a two-factor 8-item model consisting of Activity Engagement and Pain Willingness factors (SRMR?=?0.039, RMSEA?=?0.063, CFI?=?0.973, TLI?=?0.960) was superior to both the CPAQ and CPAQ with an item removed. The CPAQ and CPAQ-8 total scores were highly correlated (r?=?0.93). After accounting for pain intensity, the CPAQ-8 was a significant predictor of depression, anxiety, stress, and disability. The subscales of the CPAQ-8 were both unique contributors to depression and disability in regression analyses, after accounting for pain intensity and kinesiophobia, and after accounting for pain intensity and catastrophizing.
Conclusions
The CPAQ-8 has a sound factor structure and similar psychometric properties to the CPAQ; it may have clinical utility as a measure of pain acceptance in treatment-seeking, chronic pain patients. 相似文献
