ABSTRACT: OBJECTIVES:Heavy alcohol intake may exacerbate gastrointestinal (GI) symptoms in adults with irritable bowel syndrome (IBS); however, the role of alcohol in IBS is unclear. We investigated prospective associations between daily patterns of alcohol intake and next day's GI symptoms using daily diaries.METHODS:In an observational study of women aged 18-48 years with IBS and healthy controls, participants recorded daily GI symptoms, alcohol intake, caffeine intake, and cigarette smoking for ∼1 month. GI symptoms included abdominal pain, abdominal bloating, intestinal gas, diarrhea, constipation, nausea, stomach pain, heartburn, and indigestion. Binge drinking was defined as 4+ alcohol-containing drinks/day.RESULTS:Patterns of alcohol intake did not differ between IBS patients and controls. Although patterns of drinking were associated with GI symptoms among women with IBS, this was not the case with the healthy controls. The strongest associations for IBS patients were between binge drinking and the next day's GI symptoms (e.g., diarrhea, P=0.006; nausea, P=0.01; stomach pain, P=0.009; and indigestion, P=0.004), whereas moderate and light drinking either were not associated or weakly associated with GI symptoms. Associations between alcohol intake and GI symptoms were stronger for women with IBS-diarrhea than for IBS-constipation or IBS-mixed. Effects of binge drinking on GI symptoms were strongest when comparing between individuals (rather than within individuals).CONCLUSIONS:Our findings indicate that IBS symptoms differ according to the pattern of alcohol intake among IBS patients, suggesting that the pattern of drinking may in part explain the inconsistent findings between alcohol and IBS symptoms.Am J Gastroenterol advance online publication, 8 January 2013; doi:10.1038/ajg.2012.414.

ABSTRACT: The aims of this exploratory study were to examine whether tryptophan hydroxylase (TPH) gene polymorphisms are associated with psychosocial factors in women with irritable bowel syndrome (IBS). TPH is the rate-limiting enzyme in the biosynthesis of serotonin and has two isoforms, TPH1 and TPH2. Four single nucleotide polymorphisms (SNPs) in the TPH1 gene and one SNP in the TPH2 gene were selected based on previous studies investigating associations between these SNPs and psychiatric or behavioral disorders. One hundred ninety-nine Caucasian women with IBS were included. Results of univariate analysis showed no association between TPH1and TPH2 gene SNPs and current level of psychological distress or psychiatric illness. However, TPH1 gene SNPs were associated with IBS-related cognitions (rs4537731 and rs21105) and quality of life (rs684302 and rs1800532), in particular the mental health and energy subscales. These associations were independent of the subjects' levels of gastrointestinal symptoms. These results suggest that patients' perception of their illness, and of the impact it has on their lives, may be subject to genetic influences, in this case sequence variants in TPH1. However, caution should be used in interpreting these results given the large number of hypothesis tests performed in this exploratory hypothesis-generating study, and the results should be considered tentative until confirmed in an independent sample.

ABSTRACT: Women with irritable bowel syndrome (IBS) report sexual dysfunction. Comprehensive self-management (CSM) intervention has been shown to reduce gastrointestinal, psychological, and somatic symptoms in IBS women. Whether this intervention also reduces sexual dysfunction is not known.
We sought to compare demographic and clinical factors in IBS women with and without sexual dysfunction as defined by the Arizona sexual experiences scale (ASEX) and to test the effects of CSM treatment on sexual dysfunction scores and on the sexual relations subscale of an IBS quality of life (IBSQOL) scale which measures the effect of IBS on sexual QOL.
IBS (Rome II) women enrolled in a randomized clinical trial of CSM treatment were characterized as having sexual dysfunction (N = 89) or not (N = 86) at baseline based on ASEX criteria. Baseline characteristics and symptoms were compared between the two groups. Post-intervention changes were compared between the CSM and the usual care arms of the randomized trial.
Women meeting ASEX criteria for sexual dysfunction were older, had higher lifetime depression and antidepressant use, more primary care/MD visits, fewer mental healthcare visits, and greater sleep disturbance than those without sexual dysfunction. No significant group differences in gastrointestinal or somatic symptoms were observed. Compared with usual care treatment, CSM increased sexual QOL scores and had a weaker effect on ASEX scores.
Severity of IBS symptoms at baseline did not differ between IBS women with or without sexual dysfunction. The CSM intervention can reduce the effect of IBS on sexual QOL.

ABSTRACT: Immune responses to brain antigens occur after stroke, and experimental studies show that the likelihood of developing a detrimental autoimmune response to these antigens is increased by systemic inflammation at the time of stroke. The aim of this study was to determine if patients who developed infection in the poststroke period would be similarly predisposed to develop autoimmune responses to central nervous system antigens.
We enrolled 114 patients within 72 hours of ischemic stroke. Clinical and demographic data were obtained, and cellular immune responses to a panel of central nervous system antigens were assessed during the initial week and again at Day 90. Outcome was assessed using the modified Rankin Scale.
Patients who developed an infection, especially pneumonia, in the 15 days after stroke were more likely to evidence a Th1(+) response to myelin basic protein and glial fibrillary acidic protein (P=0.019 and P=0.039, respectively) at 90 days after stroke. Further, more robust Th1 responses to myelin basic protein at 90 days were associated with a decreased likelihood of good outcome, even after adjusting for baseline stroke severity and patient age (OR, 0.477; 95% CI, 0.244 to 0.935; P=0.031).
This study demonstrates that immune responses to brain antigens occur after stroke. Although these responses are likely to be an epiphenomenon of ischemic brain injury, the response to myelin basic protein appears to have clinical consequences. The potential role of postischemic autoimmune-mediated brain injury deserves further investigation.

ABSTRACT: Self-management programs that include cognitive behavioral strategies have been shown to improve gastrointestinal (GI) symptoms, psychological distress, and quality of life (QoL) in persons with irritable bowel syndrome (IBS). However, less is known about the physiological impact of such a change. As part of a randomized controlled trial using a comprehensive self-management (CSM) intervention (n = 126) compared to usual care (UC; n = 62), cortisol levels were measured in 4 weekly first morning urine samples at baseline and at 3-, 6-, and 12-month follow-up. In addition, diary (28 days) ratings of stress were recorded at baseline, 3, 6, and 12 months. The omnibus test of all three outcome times showed no differences in urine cortisol levels between the CSM and UC groups (p = .400); however, at 3 months the CSM group had significantly higher cortisol levels than the UC group (p = .012). The CSM group reported lower daily stress levels (p = .046 from the omnibus test of all 3 time points) than the UC group, with the effect getting stronger over time. Despite marked improvements in reported stress and previously reported GI and psychological distress symptoms at later follow-ups, the CSM program did not reduce urine cortisol levels in adults with IBS. These results suggest that the first-void urine cortisol levels are not reflective of self-reported daily stress in this patient population.

ABSTRACT: The Living Well With Stroke study has demonstrated effectiveness of a brief psychosocial treatment in reducing depressive symptoms after stroke. The purpose of this analysis was to determine whether key variables associated with prevalence of poststroke depression also predicted treatment response.
Response to a brief psychosocial/behavioral intervention for poststroke depression was measured with the Hamilton Rating Scale for Depression. Analysis of covariance models tested for interaction of potential predictor variables with treatment group on percent change in Hamilton Rating Scale for Depression from pre- to post-treatment as an outcome.
Initial depression severity, hemispheric location, level of social support, age, gender, and antidepressant adherence did not interact with the treatment with respect to percent change in Hamilton Rating Scale for Depression when considered 1 at a time. Participants who carried 1 or 2 s-alleles at the 5-HTTLPR serotonin transporterpolymorphism or 1 or 2 9- or 12-repeats of the STin2 VNTR polymorphism had significantly better response to psychosocial treatment than those with no s-alleles or no 9- or 12-repeats.
Opposite to the effects of antidepressant drug treatment with selective serotonin reuptake inhibitors, the Living Well With Stroke psychotherapy intervention was most effective in 5-HTTLPR s-allele carriers and STin2VNTR 9- or 12-repeat carriers.

ABSTRACT: Irritable bowel syndrome (IBS) has traditionally been classified by stooling pattern (e.g., diarrhea-predominant). However, other patterns of symptoms have long been recognized, e.g., pain severity. Our objective was to examine the utility of subtyping women with IBS based on pain/discomfort severity as well as predominant bowel pattern.
Women (n = 166) with IBS completed interviews, questionnaires, and kept a diary for 28 days. Rome II questionnaire items eliciting the past year recall of hard and loose stools, and frequency and severity of abdominal pain or discomfort were used to classify participants into six subtypes-three bowel pattern categories by two pain/discomfort severity categories. Concordance of these subtypes with corresponding diary items was examined. Analysis of variance (ANOVA) tested the relationship of bowel pattern and pain categories to measures of quality of life and symptoms.
There is moderate congruence of the retrospective classification of bowel pattern and pain/discomfort severity subtypes with prospectively reported stool frequency and consistency and pain severity. Quality of life, impact of IBS on work and daily activities, and cognitive beliefs about IBS differed significantly based on abdominal pain/discomfort category but not on predominant bowel pattern. There is evidence of an interaction, with the effect of pain severity being strong in the IBS-diarrhea and IBS-mixed groups, but this was absent in the IBS-constipation group. Similar results hold for most diary symptoms, except for those directly related to bowel pattern.
Overall, the distress of IBS is more strongly related to the severity of abdominal pain/discomfort than is the predominant stool pattern in patients with IBS. Categorizing IBS patients by abdominal pain/discomfort severity in conjunction with predominant bowel pattern may be useful to clinicians and researchers in developing more effective management.

ABSTRACT: The goal of this correlational study was to explore the relationship between Korean immigrant discipline (e.g., positive, appropriate, and harsh discipline) and children's social competence and behavior problems. Self-report data were collected from 58 mothers and 20 fathers of children aged from 3 to 8 years. Only paternal harsh discipline was positively correlated with children's behavior problems. Among specific discipline strategies, maternal physical affection, correcting misbehaviors, and reasoning were positively correlated with children's social competence. Paternal physical punishment (e.g., spanking, hitting, and raising arms) was positively correlated with children's behavior problems. Immigrant fathers need to learn alternative ways of managing children's misbehaviors.

ABSTRACT: Early childhood traumatic experiences (e.g., abuse or neglect) may contribute to sleep disturbances as well as to other indicators of arousal in patients with irritable bowel syndrome (IBS). This study compared women with IBS positive for a history of childhood abuse and/or neglect to women with IBS without this history on daily gastrointestinal (GI), sleep, somatic, and psychological symptom distress, polysomnographic sleep, urine catecholamines (CAs) and cortisol, and nocturnal heart rate variability (HRV).
Adult women with IBS recruited from the community were divided into two groups: 21 with abuse/neglect and 19 without abuse/neglect based on responses to the Childhood Trauma Questionnaire (CTQ; physical, emotional, sexual abuse, or neglect). Women were interviewed, maintained a 30-day symptom diary, and slept in a sleep laboratory. Polysomnographic and nocturnal HRV data were obtained. First-voided urine samples were assayed for cortisol and CA levels.
Women with IBS positive for abuse/neglect history were older than women without this history. Among GI symptoms, only heartburn and nausea were significantly higher in women with abuse/neglect. Sleep, somatic, and psychological symptoms were significantly higher in women in the abuse/neglect group. With the exception of percentage of time in rapid eye movement (REM) sleep, there were few differences in sleep-stage variables and urine hormone levels. Mean heart rate interval and the natural log of the standard deviation of RR intervals for the entire sleep interval (Ln SDNN) values were lower in those who experienced childhood abuse/neglect.
Women with IBS who self-report childhood abuse/neglect are more likely to report disturbed sleep, somatic symptoms, and psychological distress. Women with IBS should be screened for adverse childhood events including abuse/neglect.

ABSTRACT: This study examined a cultural response set to positive affect items and depressive symptom items in CES-D among 172 Korean immigrants. Bi-dimensional acculturation approach, which considers maintenance of Korean Orientation and adoption of American Orientation, was utilized. As Korean immigrants increased their American Orientation, they tended to score higher on positive affect items, with no changes occurring in depressive symptom items. Korean Orientation was not related to either positive affect items or depressive symptom items. Korean immigrants have a response bias toward positive affect items in CES-D, which decreases as they adopt more American Orientation. CES-D lacks cultural equivalence for Korean immigrants.

ABSTRACT: Two weeks of touch intervention, either Yakson or Gentle Human Touch (GHT) have been shown to reduce the levels of stress hormones. This study evaluated the acute impact of both interventions on state during and immediately after touch. Forty preterm infants with a gestational age of < or =34 weeks received either Yakson or GHT for 15 days. A significantly greater sleeping state was identified in both groups after touch. This effect was significantly stronger with Yakson than GHT. During touch, about half the Yakson infants showed an arousal effect while the GHT infants showed little change. Both interventions left the babies calmer after touch. This calming effect is consistent with the previously observed effect on stress hormones and should be beneficial in terms of growth and development. Yakson had an arousing effect on a subset of the infants during touch, which possibly could be beneficial in terms of social development.

ABSTRACT: Psychological and behavioral therapies are being increasingly used for symptom management in patients with irritable bowel syndrome (IBS). The aims of this study were to compare two delivery modes for a comprehensive self-management (CSM) intervention, primarily by telephone vs. entirely in person, and to compare each with usual care (UC).
Adults with IBS were recruited through community advertisement. Subjects (N=188) were randomly assigned to three groups: one in which all nine weekly CSM sessions were delivered in person, one in which six of the nine sessions were conducted over telephone, and one in which subjects received UC. Primary outcome measures were a gastrointestinal (GI) symptom score based on six symptoms from a daily diary and disease-specific quality of life (QOL). These and other outcomes were assessed at baseline and at 3, 6, and 12 months after randomization. Mixed model analyses tested for differences between the three groups in each outcome variable at the three follow-up occasions, controlling for the baseline level of each outcome.
Both GI symptom score and QOL showed significantly greater improvement in the two CSM groups than in the UC group (P<0.001), with the magnitude of this difference being quite similar for the three follow-up time points. The two CSM groups experienced a very similar degree of improvement, and there were no statistically significant differences between the two.
A CSM program is efficacious whether delivered primarily by telephone or totally in person, and there is no evidence that replacing six of the in-person sessions by telephone sessions reduces the efficacy of the intervention.

ABSTRACT: Depression after stroke is prevalent, diminishing recovery and quality of life. Brief behavioral intervention, adjunctive to antidepressant therapy, has not been well evaluated for long-term efficacy in those with poststroke depression.
One hundred one clinically depressed patients with ischemic stroke within 4 months of index stroke were randomly assigned to an 8-week brief psychosocial-behavioral intervention plus antidepressant or usual care, including antidepressant. The primary end point was reduction in depressive symptom severity at 12 months after entry.
Hamilton Rating Scale for Depression raw score in the intervention group was significantly lower immediately posttreatment (P<0.001) and at 12 months (P=0.05) compared with control subjects. Remission (Hamilton Rating Scale for Depression <10) was significantly greater immediately posttreatment and at 12 months in the intervention group compared with the usual care control. The mean percent decrease (47%+/-26% intervention versus 32%+/-36% control, P=0.02) and the mean absolute decrease (-9.2+/-5.7 intervention versus -6.2+/-6.4 control, P=0.023) in Hamilton Rating Scale for Depression at 12 months were clinically important and statistically significant in the intervention group compared with control.
A brief psychosocial-behavioral intervention is highly effective in reducing depression in both the short and long term.

ABSTRACT: Polymorphisms of the serotonin transporter gene (SERT) have been associated with mental illness. In people with long-term medical conditions, variants of the 5-HTTLPR and STin2 VNTR polymorphisms of SERT have been shown to confer a heightened vulnerability to comorbid depression.
To determine whether the 5-HTTLPR, STin2 VNTR, and rs25531 polymorphisms of SERT are associated with poststroke depression (PSD) in stroke survivors.
A case-control study in which stroke survivors were screened for depressive symptoms and assigned to either a depressed group or a nondepressed group.
Outpatient clinic.
Seventy-five stroke survivors with PSD and 75 nondepressed stroke survivors.
Blood or saliva samples were collected from each participant for DNA extraction and genotyping.
The associations between the 5-HTTLPR, STin2 VNTR, and rs25531 polymorphisms and PSD.
Individuals with the 5-HTTLPR s/s genotype had 3-fold higher odds of PSD compared with l/l or l/xl genotype carriers (odds ratio, 3.1; 95% confidence interval, 1.2-8.3). Participants with the STin2 9/12 or 12/12 genotype had 4-fold higher odds of PSD compared with STin2 10/10 genotype carriers (odds ratio, 4.1; 95% confidence interval, 1.2-13.6). An association of rs25531 with PSD was not shown.
The 5-HTTLPR and the STin2 VNTR, but not the rs25531, polymorphisms of SERT are associated with PSD in stroke survivors. This gives further evidence of a role of SERT polymorphisms in mediating resilience to biopsychosocial stress.

ABSTRACT: Korean American adolescents tend to experience more mental health problems than adolescents in other ethnic groups.
The goal of this study was to examine the association between Korean American parent-adolescent relationships and adolescents' depressive symptoms in 56 families.
Thirty-nine percent of adolescents reported elevated depressive symptoms. Adolescents' perceived low maternal warmth and higher intergenerational acculturation conflicts with fathers were significant predictors for adolescent depressive symptoms.
The findings can be used to develop a family intervention program, the aim of which would be to decrease adolescent depressive symptoms by promoting parental warmth and decreasing parent-adolescent acculturation conflicts.

ABSTRACT: This study compared heart-rate variability (HRV) indices of autonomic nervous system function during two nights of sleep between women with irritable bowel syndrome (IBS, n = 35) and healthy controls (n = 38), and among subgroups within the IBS sample based on predominant stool patterns. HRV measures were estimated in conjunction with polysomnographic sleep scoring to define sleep stage-specific autonomic indices. Overall, there were no differences in indicators of HRV between women with IBS and controls. However, within the IBS group, women with diarrhea-predominant IBS demonstrated significantly increased parasympathetic modulation and lower sympathetic/parasympathetic nervous system balance across sequential NREM periods and REM cycles compared to both constipation-predominant and alternating IBS subjects. These results suggest that differences in mean level of HRV between predominant bowel groups in IBS patients are large, and that this effect is consistent in the different sleep stages and at different times of night.

ABSTRACT: Chronic pain is a common, disabling problem in older adults. Pain self-management training is a multimodal therapy that has been found to be effective in young to middle-aged adult samples; however, few studies have examined the effectiveness of this therapy in older adults. In this randomized, controlled trial, we evaluated a pain self-management training group (SMG) intervention as compared with an education-only (BOOK) control condition. Participants, 65 years of age or older who experienced persistent, noncancer pain that limited their activities, were recruited from 43 retirement communities in the Pacific Northwest of the United States. The primary outcome was physical disability, as measured by the Roland-Morris Disability Questionnaire. Secondary outcomes were depression (Geriatric Depression Scale), pain intensity (Brief Pain Inventory), and pain-related interference with activities (Brief Pain Inventory). Randomization occurred by facility to minimize cross-contamination between groups. Two-hundred and fifty-six individuals, mean age=81.8 (SD: 6.5), enrolled and 218 completed the study. No significant differences in outcomes were found between groups at post-intervention, 6-month follow-up, or 12-month follow-up. The SMG group showed a significantly greater increase over time, relative to the BOOK group, in two process measures, as measured by the Chronic Pain Coping Inventory: use of relaxation and use of exercise/stretching. In both cases, the increase was greatest from baseline to the post-intervention assessment. Study findings indicate that additional research is needed to determine the most effective content and delivery methods for self-management therapies targeted at older adults with chronic pain.

ABSTRACT: Traditional Korean American discipline is characterized by a lack of expression of affection and use of harsh discipline.
The purpose of this study was to pilot test the effect of the Incredible Years Parenting Program among Korean American mothers.
A randomized controlled experimental study design was used; 29 first-generation Korean American mothers of young children (3-8 years old) were randomly assigned to intervention (n=20) and control (n=9) groups. Intervention group mothers received a 12-week parenting program. Control group mothers did not receive the intervention. Mothers reported on discipline styles (positive, appropriate, and harsh), level of acculturation, and their child's outcomes (behavioral problems and social competence) at pre-, post-, and 1-year follow-up intervals.
After completing the program, intervention group mothers significantly increased use of positive discipline as compared to control group mothers. Among intervention group mothers, high-acculturated mothers significantly increased appropriate discipline whereas low-acculturated mothers significantly decreased harsh discipline. In the 1-year follow-up, intervention group mothers maintained the significant effect for positive discipline.
Providing this program appears to be a promising way of promoting positive discipline among Korean American mothers.

ABSTRACT: This study investigates the association of psychological symptoms with the distribution of two serotonin transporter gene (SERT) polymorphisms, located in the promoter region (5-HTTLPR) and in intron 2 (STin2 VNTR), in patients with irritable bowel syndrome (IBS). Participants, 21 men and 117 women, were assessed for mental health history and current psychological distress. A blood sample was used for genotyping. Participants who were homozygous for the short allele of 5-HTTLPR or carried a STin2.9 VNTR allele were significantly more likely to have a history of depression. Participants did not differ by genotype in their history of anxiety or suicidal ideation nor in their current levels of depression, anxiety, or general psychological distress. The results support a biopsychosocial model of IBS in which SERT genotype modifies the risk for depressive episodes. Long term, practitioners may individualize treatment of patients with IBS using genotype as one of the factors.

ABSTRACT: Clinical bedside monitoring systems do not provide prominent displays of data on cerebral perfusion pressure (CPP). Immediate visual feedback would allow more rapid intervention to prevent or minimize suboptimal pressures.
To evaluate the effect of a highly visible CPP display on immediate and long-term functional outcome in patients with traumatic brain injury.
A total of 157 patients with traumatic brain injury at a level 1 trauma center who had invasive arterial blood pressure and intracranial pressure monitoring were randomized to beds with or without an additional, prominent continuous CPP display. Primary end points were scores on the Extended Glasgow Outcome Scale (GOSE) and Functional Status Examination (FSE) 6 months after injury. Secondary end points were GOSE scores at discharge and 3 months after injury and FSE score 3 months after injury.
Although GOSE and FSE scores at 6 months were better in the group with the highly visible CPP display, the differences were not significant. Slope of recovery for GOSE and FSE over all follow-up time points did not differ significantly between groups. However, the intervention's positive effect on odds of survival at hospital discharge was strong and significant. Within a subgroup of more severely injured patients, the intervention group was much less likely than the control group to have CPP deviations.
The presence of a highly visible display of CPP was associated with significantly better odds of survival and overall condition at discharge.
