Childhood trauma and psychiatric comorbidities in patients with depressive disorder in primary care in Chile

Childhood trauma is associated with different psychiatric disorders during adulthood. These disorders are often presented in comorbidity with depression. Objective: To establish the relationship between psychiatric comorbidities and childhood traumatic events in patients with depression in Chile. Methods: Three hundred and ninety-four patients with major depression were assessed using the MINI International Neuropsychiatric Interview and a screening for childhood trauma. Results: Social anxiety disorder was associated with having witnessed domestic violence during childhood (OR = 2.2, CI 1.2 - 3.8), childhood physical abuse (OR = 2.7, CI 1.6 - 4.4), physical injury associated with physical abuse (OR = 2.3, CI 1.3 - 4.7) and sexual abuse by a non-relative (OR = 2.7, CI 1.3 - 4.2). Posttraumatic stress disorder was associated with physical injury associated with physical abuse (OR = 1.9, CI 1.1 - 3.6), sexual abuse by a relative (OR = 3.2, IC 1.8 - 5.9) and sexual abuse by a non-relative (OR = 2.2, CI 1.2 - 4.1). Antisocial personality disorder was associated with traumatic separation from a caregiver (OR = 3.2, CI 1.2 - 8.5), alcohol abuse by a family member (OR = 3.1, CI 1.1 - 8.1), physical abuse (OR = 2.8, CI 1.1 - 6.9) and sexual abuse by a non-relative (OR = 4.8, CI 1.2 – 11.5). Panic disorder was associated with sexual abuse by a relative (OR = 1.9, CI 1.1 - 3.1). Generalized anxiety disorder was associated with sexual abuse by a non-relative (OR = 1.9, CI 1.1- 3.3). Conclusions: Further clinical recognition is required in patients seeking help for depression in primary care. This recognition must take into account the patient’s current psychiatric comorbidities and adverse childhood experiences.     

Increased mortality among women with Rose angina who have not presented with ischaemic heart disease.

BACKGROUND: Little is known about the clinical importance of disease that is not presented to healthcare services. AIM: To determine the 5-year mortality among those with angina symptoms, known or not known by their general practitioner (GP) to have ischaemic heart disease (IHD). DESIGN: A prospective cohort study. SETTING: The study was conducted in the United Kingdom as part of the Royal College of General Practitioners' Oral Contraception Study. METHOD: In 1994-1995 women (n = 11,797) still under GP observation were sent a questionnaire that inquired about their smoking habits, other lifestyle issues, general health, and selected symptoms (including chest pain, assessed using the Rose angina questionnaire). The main outcome measure was the chances (odds) of dying during the next 5 years, among those with and without exertional chest pain, Rose angina or Rose myocardial infarction (MI), stratified by documented history of IHD. RESULTS: Overall, the lifetime prevalence of any exertional chest pain was 10.1% (95% confidence interval [CI] = 9.5 to 10.8); grade I Rose angina was 6.1% (95% CI = 5.6 to 6.6); grade II Rose angina was 1.3% (95% CI = 1.1 to 1.6); and Rose MI was 4.4% (95% CI = 4.0 to 4.9). The prevalence of each condition tended to increase with age, social class, parity, body mass index, and documented history of IHD. The proportion of women documented as having IHD was 23% among those with any exertional chest pain, 21.7% for grade I Rose angina, 37.7% for grade II Rose angina, and 31.4% for Rose MI. Compared to women without Rose angina, significantly higher odds ratios for all-cause mortality were observed among women with grade I Rose angina and no documented history of IHD (adjusted odds ratio [AOR] = 1.71, 95% CI = 1.05 to 2.79); those with grade II Rose angina and documented IHD (AOR = 3.94, 95% CI = 1.58 to 9.83); and women with grade II Rose angina and no documented history of IHD (AOR = 3.35, 95% CI = 1.47 to 7.62). CONCLUSIONS: Women with angina symptoms that have not been documented by their GP appear to have an increased risk of future mortality. Research is needed to determine the best way of identifying and managing these individuals.     

Do asthma and allergy influence subsequent pet keeping? An analysis of childhood and adulthood

BACKGROUND: Asthma and allergy might influence the choice of keeping pets, leading to apparent protective effects of pets on allergic disease. OBJECTIVE: We investigated the effects of asthma and allergy on subsequent pet keeping in childhood and adulthood. METHODS: Information about asthma and pet keeping at ages 0 to 4, 5 to 15, 20 to 44, and 26 to 56 years was provided by 9812 subjects participating in the 9-year follow-up of the European Community Respiratory Health Survey. RESULTS: In childhood asthma debut at younger than 5 years was associated with less cat keeping at 5 to 15 years (odds ratio [OR], 0.60; 95% CI, 0.44-0.82), an effect only observed when the parents did not have asthma or allergy (P(interaction) = .045). Childhood asthma did not influence adult pet ownership, unless there were adult symptoms. Adults less often acquired cats at follow-up if they had 3 or more asthma symptoms (OR, 0.78; 95% CI, 0.64-0.95), were taking asthma medication (OR, 0.48; 95% CI, 0.31-0.74), had hay fever (OR, 0.75; 95% CI, 0.62-0.91), had atopy (OR, 0.75; 95% CI, 0.61-0.91), or had specific IgE to cat (OR, 0.57; 95% CI, 0.39-0.82) at baseline. Adults who already had pets usually continued keeping the same type of pet, except that the presence of 3 or more asthma symptoms was associated with less subsequent dog keeping (OR, 0.69; 95% CI, 0.53-0.89). Pet removal between surveys to reduce allergen was reported by 4.7%. CONCLUSION: Selective avoidance subsequent to asthma or allergy was observed for childhood cat keeping and adult cat acquisition. Avoidance would produce an apparent protective effect of cats on childhood asthma (large OR, 0.83). Avoidance was generally not observed for dogs or birds. CLINICAL IMPLICATIONS: A part of the protective effects of childhood cats on asthma and allergy can be attributed to selective avoidance.     

Mental disorders in medical inpatients and the association to severity of illness, self-rated physical disability, and health perception

In a study of 294 consecutive medical inpatients, the authors assessed a subsample of 157 patients for psychiatric diagnoses using an extensive semistructured interview, Schedules for Clinical Assessment in Neuropsychiatry (SCAN). Patients rated their health and physical functioning, and medical consultants assessed them for chronic and life-threatening diseases. A life-threatening condition increased odds for having a psychiatric diagnosis by 3.1 times (95% Confidence Interval (CI): 1.03-9.1), while a chronic medical disease had no such impact (OR=1.1; 95% CI: 0.5-2.3). In women, mental disorders were strongly associated with self-rated disability (OR=6.7; 95% CI: 1.6-27.8) and self-rated health (OR=9.4; 95% CI: 2.7-32.4). This association was absent in men (OR(disability)=0.7; 95% CI: 0.2-2.7; OR(health)=1.6; 95% CI: 0.6-4.7). Analyses included adjustment for age and gender.     

Carrying the Pain of Abuse: Gender-Specific Findings on the Relationship between Childhood Physical Abuse and Obesity in Adulthood

BackgroundChildhood abuse has been associated with negative adult health outcomes, including obesity. This study sought to investigate the association between childhood physical abuse and adult obesity, while controlling for five clusters of potentially confounding factors: childhood stressors, socioeconomic indicators, marital status, health behaviors, and mental health.MethodsRepresentative data from the 2005 Canadian Community Health Survey were selected. The response rate was approximately 84%. Gender-specific logistic regression analyses determined the association between abuse and obesity, while controlling for age and race and five clusters of potentially confounding factors. Of the 12,590 respondents with complete data, 2,787 were obese and 976 reported physical abuse as a child or adolescent by someone close to them.ResultsAmong women with childhood physical abuse compared to no abuse, the odds of obesity were 35% higher, even when controlling for age, race, and the five clusters of factors (odds ratio (OR) = 1.35; 95% confidence interval (CI) = 1.09, 1.67). Childhood physical abuse was not associated with adult obesity among men (OR = 1.12; 95% CI = 0.82, 1.53).ConclusionsThis study provides one of the first population-based, gender-specific analyses of the association between childhood physical abuse and obesity controlling for a wide range of factors. The gender-specific findings require further exploration.Key Words: Childhood physical abuse, Adverse childhood experiences, Gender, Health behaviors, Socioeconomic status, Mental health     

Antibiotic use in the first year of life and asthma in early childhood

BACKGROUND: An association between antibiotic use in early life and asthma in childhood has been reported in five retrospective studies and one longitudinal study. OBJECTIVE: To examine the relation between the use of oral antibiotics in the first year of life and asthma in early childhood. METHODS: Longitudinal follow-up of 4408 children enrolled in a health maintenance organization (HMO) from birth to the age of 5 years. RESULTS: After adjusting for sex and illnesses of the lower respiratory tract (LRIs), we found a significant association between antibiotic use in the first year of life and asthma between the ages of 1 and 2 years (odds ratio (OR) for 1-2 vs. no courses of antibiotics=1.9, 95% confidence interval (CI)=1.3-2.7; OR for 3-4 vs. no courses of antibiotics=1.6, 95% CI=1.1-2.4; OR for at least 5 vs. no courses of antibiotics=2.1, 95% CI=1.5-3.2). After adjustment for sex and LRIs in the first year of life, there was no significant association between antibiotic use in the first year of life and asthma that was initially diagnosed between the ages of 2 and 5 years and that persisted up to the age of 5 years (OR for 1-2 vs. no courses of antibiotics=1.1, 95% CI=0.8-1.4; OR for 3-4 vs. no courses of antibiotics=1.3, 95% CI=0.9-1.8; OR for at least 5 vs. no courses of antibiotics=1.0, 95% CI=0.7-1.4). Conclusions Our findings do not support the hypothesis that antibiotic use in early life is associated with the subsequent development of asthma in childhood but rather suggest that frequent antibiotic use in early life is more common among asthmatic children.     

Childhood abuse and familial violence and the risk of panic attacks and panic disorder in young adulthood

BACKGROUND: The objectives of the study were to examine linkages between exposure to childhood abuse and interparental violence and the subsequent development of panic attacks and panic disorder using data gathered on a birth cohort of 1265 New Zealand young people studied to the age of 21 years. METHOD: Data on: (a) exposure to child abuse and interparental violence; (b) the development of panic attacks and panic disorder; and (c) other childhood and related factors were gathered over the course of a 21-year longitudinal study. RESULTS: After adjustment for childhood and related factors, exposure to childhood physical abuse was associated with a significantly increased risk of later panic attack (OR 2.3, 95% CI 1.1-4.9) and panic disorder (OR 3.0, 95% CI 1.1-7.9); childhood sexual abuse was associated with a significantly increased risk of panic attack (OR 4.1, 95% CI 2.3-7.2) and a marginally significant increase risk of panic disorder (OR 2.2; 95% CI 0.98-5.0). Exposure to interparental violence was unrelated to later panic attack or disorder after adjustment. CONCLUSIONS: Exposure to childhood sexual and physical abuse was associated with increased risks of later panic attack/disorder even after adjustment for prospectively assessed confounding factors. However, exposure to interparental violence during childhood was not related to increased risk of later panic attack/disorder after adjustment. These data suggest the need for clinicians to be aware that patients with histories of childhood physical and sexual abuse may be at increased risk for panic during young adulthood.     

Breast cancer in relation to childhood parental divorce and early adult psychiatric disorder in a British birth cohort

BACKGROUND: Jacobs and Bovasso reported (Psychological Medicine 2000, 30, 669-678) that maternal death in childhood and chronic severe depression in adulthood were associated with subsequent breast cancer. We have examined the effects of parental loss in childhood and psychiatric disorder in adult life on breast cancer risk using a national birth cohort study. METHOD: Eighty-three cases of breast cancer were diagnosed in a study of 2253 women followed from birth to age 59 years. Cox proportional hazards models were used to test whether breast cancer rates were higher in women who experienced parental death and divorce before age 16, psychiatric disorders between 15 and 32 years, symptoms of anxiety and depression at 36 years, or use of antidepressant medication at 31 or 36 years than in women who did not have these experiences. RESULTS: There was no overall association between parental death, parental divorce or psychiatric disorder and the incidence of breast cancer. There was some evidence that women with more severe psychiatric disorders between the ages of 15 and 32 years were more likely to develop breast cancer early. The interaction between parental divorce and severe psychiatric disorder was non-significant (p=0.1); however, the group who experienced both these events had an increased breast cancer risk compared with those who experienced neither [hazard ratio (HR) 2.64, 95% confidence interval (CI) 1.13-6.19]. CONCLUSIONS: Our study does not provide strong support for the hypothesis that early loss or adult psychiatric disorders are associated with breast cancer. A meta-analysis is needed that uses data from all available cohort studies and investigates possible interactive effects on breast cancer risk.     

CREB1 gene polymorphisms combined with environmental risk factors increase susceptibility to major depressive disorder (MDD)

Major depressive disorder (MDD) is one of the most severe psychiatric disorders. The objective of this study was to explore the effects of CREB1 gene polymorphisms on risk of developing MDD and the joint effects of gene-environment interactions. Genotyping was performed by Taqman allelic discrimination assay among 586 patients and 586 healthy controls. A significant impact on rs6740584 genotype distribution was found for childhood trauma (P = 0.015). We did not find an association of CREB1 polymorphisms with MDD susceptibility. However, we found a significantly increased risk associated with the interactions of CREB1 polymorphisms and drinking (OR = 11.67, 95% CI = 2.52-54.18; OR = 11.52, 95% CI = 2.55-51.95 for rs11904814; OR = 4.18, 95% CI = 1.87-9.38; OR = 5.02, 95% CI = 2.27-11.14 for rs6740584; OR = 7.58, 95% CI = 2.05-27.98; OR = 7.59, 95% CI = 2.12-27.14 for rs2553206; OR = 8.37, 95% CI = 3.02-23.23; OR = 7.84, 95% CI = 2.93-20.98 for rs2551941). We also noted that CREB polymorphisms combined with family harmony and childhood trauma conferred increased susceptibility for MDD. In conclusion, polymorphisms in the CREB gene may not be independently associated with MDD risk, but they are likely to confer increased susceptibility by interacting with environmental risk factors in the Chinese population.     

Nocturia and health in women aged 40-64 years

To analyse the relationship between nocturnal micturition and health in 40- to 64-year-old women. A questionnaire study was carried out in 3669 randomly selected women (out of 6000 invited) in the County of J?mtland, Sweden. Questions were asked about the general health status of health, health development during the last 5 years, nocturnal micturition, parity, menstrual status, menopausal symptoms, hormone replacement therapy, cardiac diseases, diabetes and snoring. Poor health was reported by 10.4%. In 24.1% of the women health development had been unfavourable in the last 5 years. Poor health was reported by 4.7% of women without nocturnal micturition, and by 11.2, 20.1 and 39.0% (P<0.0001) of women with one, two, and three or more nocturnal voiding episodes, respectively. In a multiple logistic regression analysis significant independent correlates of health were: one versus no nocturnal micturitions (odds ratio [OR] 2.2; confidence interval [CI] 1.5-3.3), two versus none (OR 3.2; 1.9-5.3), and three or more versus none (OR 6.5; 3.5-11.9), spasmodic chest pain (OR 6.6; CI 3.0-14.5), irregular heart beats (OR 3.0; CI 2.1-4.3), diabetes (OR 5.1; CI 2.8-9.4), leg oedema> or =6 days/month versus <6 days/month (OR 23; CI 1.6-3.3), snoring: < or =3 times/week versus never (OR 1.4; CI 1.0-2.0), snoring 4-7 times/week versus never (OR 1.6; CI 1.1-2.2), being<5 years after versus being before the menopause (OR 1.6; 95% CI 1.0-2.5), 5-9 years after versus before the menopause (OR 1.7; CI 1.0-2.9), > or =10 years after versus before the menopause (OR 2.2; CI 1.3-3.7), diuretic treatment (OR 2.8; CI 1.7-4.6). The perceived state of health in 40- to 64- year-old women is profoundly affected by nocturia, independently of heart diseases, diabetes, snoring, age and menopausal status.     

Childhood adversity, recent life events and depression in late life

BACKGROUND: The study investigates whether persons who have experienced childhood adversity are more likely to develop depressive symptoms when faced with recent events. METHOD: Data were used from a population-based sample, aged 55 to 85 years (n=1887), which were not depressed at baseline. Childhood adversities and recent stressful life events were retrospectively assessed. Depressive symptoms were measured with the CES-D. RESULTS: 14.4% of our sample experienced adverse events during childhood (<18 yrs) and 35.4% experienced recent events. Associations of depressive symptoms were found with both, childhood adversity (OR 1.80, 95% CI 1.21-2.69) and recent life events (OR 1.42, 95% CI 1.01-2.00). The effect of recent events on depressive symptoms was not modified by childhood adversity. LIMITATIONS: Underreporting may be present due to unwillingness to report embarrassing events or to disclose painful memories. CONCLUSIONS: No evidence was found for the assumption that older persons were more vulnerable for depression in reaction to recent life events when they were exposed to childhood adversity.     

Suicides and serious suicide attempts: two populations or one?

BACKGROUND: Few studies have examined the extent to which populations of suicides and attempted suicides are similar, or different. This paper compares suicides and serious suicide attempts in terms of known risk factors for suicidal behaviour. METHODS: Using case-control methodology, risk factors for suicidal behaviour were examined in 202 individuals who died by suicide, 275 individuals who made medically serious suicide attempts and 984 randomly selected control subjects. Based on data from significant others, measures used spanned sociodemographic factors, childhood experiences, psychiatric morbidity and psychiatric history, exposure to recent stressful life events and social interaction. RESULTS: Multiple logistic regression identified the following risk factors that were common to suicide and serious suicide attempts: current mood disorder; previous suicide attempts; prior outpatient psychiatric treatment; admission to psychiatric hospital within the previous year; low income; a lack of formal educational qualifications; exposure to recent stressful interpersonal, legal and work-related life events. Suicides and suicide attempts were distinguished in the following ways: suicides were more likely to be male (OR = 1.9, 95% CI 1.1, 3.2); older (OR = 1.03, 95% CI 1.02, 1.04); and to have a current diagnosis of non-affective psychosis (OR = 8.5, 95% CI 2.0, 35.9). Suicide attempts were more likely than suicides to have a current diagnosis of anxiety disorder (OR = 3.5, 95% CI 1.6, 7.8) and to be socially isolated (OR = 2.0, 95% CI 1.2, 3.5). These findings were confirmed by discriminant function analysis, which identified two functions that described the three subject groups: the first function discriminated the two suicide groups from control subjects on a dimension corresponding to risk factors for suicide; the second function discriminated suicide from suicide attempt subjects on a series of factors including gender, non-affective psychosis and anxiety disorder. CONCLUSIONS: Suicides and medically serious suicide attempts are two overlapping populations that share common psychiatric diagnostic and history features, but are distinguished by gender and patterning of psychiatric disorder.     

The prevalence of and potential risk factors for female urinary incontinence in Beijing, China

OBJECTIVES: To survey and evaluate the prevalence and potential risk factors of female urinary incontinence (UI) in Beijing, China. DESIGN: A population-based cross-sectional study was performed from April to July 2005. We randomly sampled 1.0% of female residents aged 20 years and older from year 2000 national census data, totaling 5,300 women. All of the women were interviewed face to face using a modified questionnaire based on the International Consultation on Incontinence Questionnaire-Female Lower Urinary Tract Symptoms. Data were collected and analyzed. RESULTS: The overall prevalence of female UI was 38.5%. Prevalence rates of female stress urinary incontinence (SUI), female urge urinary incontinence, and female mixed urinary incontinence were 22.9%, 2.8%, and 12.4%, respectively. The prevalence rate of female UI was more than 50% in postmenopausal women. In multiple logistic models, multiple vaginal deliveries (odds ratio [OR]=2.1; 95% CI: 1.443-3.179), age (OR=1.7; 95% CI: 1.039-2.742), postmenopausal status (OR=1.5; 95% CI: 1.182-1.983), chronic pelvic pain (OR=1.4; 95% CI: 1.134-1.814), obesity (OR=1.4; 95% CI: 1.205-1.721), lack of exercise (OR=1.3; 95% CI: 1.105-1.509), constipation (OR=1.3; 95% CI: 1.109-1.586), and hypertension (OR=1.2; 95% CI: 1.053-1.474) were identified as potential risk factors of female SUI. No association between female SUI and offspring birth weight, occupation, or chronic diseases was observed in this study. Only 12.8% of women with UI and 7.4% of women with SUI seek medical help. CONCLUSIONS: UI is a major disorder that affects female quality of life. The prevalence of female UI is high (38.5%) in Beijing. Among the different types of UI, SUI was the most prevalent (22.9%). Potential risk factors identified for female SUI were multiple vaginal deliveries, age, postmenopausal status, chronic pelvic pain, obesity, lack of exercise, constipation, and hypertension.     

The profile and risks of suicidal behaviours in the Nigerian Survey of Mental Health and Well-Being

BACKGROUND: Suicide is a leading cause of death worldwide but information about it is sparse in Sub-Saharan Africa. Suicide-related behaviours can provide an insight into the extent of this compelling consequence of mental illness. METHOD: Face-to-face interviews were conducted with a representative sample of persons aged 18 years and over (n=6752) in 21 of Nigeria's 36 states (representing about 57% of the national population). Suicide-related outcomes, mental disorders, as well as history of childhood adversities were assessed using the World Health Organization (WHO) Composite International Diagnostic Interview (CIDI). RESULTS: Lifetime prevalence estimates of suicide ideation, plan and attempts were 3.2% [95% confidence interval (CI) 1.4-6.5], 1.0% (95% CI 0.4-7.5) and 0.7% (95% CI 0.5-1.0) respectively. Almost two of every three ideators who made a plan went on to make an attempt. The highest risks for transition from ideation to plan and from plan to attempt were in the first year of having ideation or plan respectively. Mental disorders, especially mood disorders, were significant correlates of suicide-related outcomes. Childhood adversities of long separation from biological parents, being raised in a household with much conflict, being physically abused, or being brought up by a woman who had suffered from depression, anxiety disorder, or who had attempted suicide were risk factors for lifetime suicide attempt. CONCLUSIONS: History of childhood adversities and of lifetime mental disorders identify persons at high-risk for suicide-related outcomes. Preventive measures are best delivered within the first year of suicide ideation being expressed.     

Risk of childhood asthma and allergic rhinitis in relation to pregnancy complications

BACKGROUND: Events occurring during fetal life may affect the development of the immune and respiratory systems and increase the risk of asthma and allergic diseases. OBJECTIVES: We sought to elaborate the relations between the occurrence of pregnancy complications and other pregnancy-related conditions and the risk of bronchial obstruction during the first 2 years of life and the occurrence of asthma and allergic rhinitis by the age of 4 years. Pregnancy complications were considered both as predictors of the health outcomes and as possible effects caused by other prenatal factors. METHODS: A population-based, 4-year, cohort study was carried out involving 2531 children born in Oslo, Norway. We collected information on maternally related (hyperemesis, hypertension, and preeclampsia) and uterus-related complications in pregnancy (antepartum hemorrhage, preterm contractions, insufficient placenta, and restricted growth of the uterus) and the child's health and environmental exposures at birth and at 6, 12, 18, and 24 months and 4 years of age. The outcomes of interest were bronchial obstruction during the first 2 years and asthma and allergic rhinitis at the age of 4 years. RESULTS: In a logistic regression analysis adjusting for potential confounders, uterus-related, but not other pregnancy-related, complications increased the risk of bronchial obstruction (odds ratio [OR], 2.1; 95% confidence interval [CI], 1.3-3.4), asthma (OR, 3.0; 95% CI, 1.8-5.4), and allergic rhinitis (OR, 2.9; 95% CI, 1.6-5.2). These relations were similar in children of atopic and nonatopic parents. CONCLUSIONS: Uterus-related complications in pregnancy increase the risk of having asthma and allergic rhinitis in childhood.     

Pain, Mood, and Substance Abuse in HIV: Implications for Clinic Visit Utilization, Antiretroviral Therapy Adherence, and Virologic Failure

BACKGROUND:: Cooccurring pain, mood disorders, and substance abuse are common in HIV-infected patients. Our objective was to investigate the relationship between pain, alone and in the context of mood disorders and substance abuse, on clinic utilization, antiretroviral therapy adherence, and virologic suppression. METHODS:: Pain, mood disorders, and substance abuse were assessed at the first visit. No-show and urgent visits were measured over a 1-year period. Models were adjusted for age, race, sex, insurance status, CD4 T-lymphocyte count, and HIV risk factor. RESULTS:: Among 1521 participants, 509 (34%) reported pain, 239 (16%) had pain alone, 189 (13%) had pain and a mood disorder, and 30 (2%) had pain and substance abuse. In univariate models, participants with pain, mood disorders, and substance abuse had higher odds of a no-show visit than those without these conditions [odds ratio (OR), 1.4; 95% confidence interval (CI), 1.1-1.8; OR, 1.5; 95% CI, 1.2-1.9; OR, 2.0; 95% CI, 1.4-2.8, respectively]. In the multivariable model, pain increased the odds of a no-show visit only in participants without substance abuse (OR, 1.5; 95% CI, 1.1-1.9) and pain reduced the odds of a no-show visit in participants with substance abuse (OR, 0.5; 95% CI, 0.2-0.9; P for interaction = 0.0022). CONCLUSIONS:: In this study, pain increased the odds of no-show visits but only for participants without substance abuse. Because pain, mood disorders, and substance abuse are highly prevalent in HIV-infected patients, our findings have implications for HIV treatment success. Interventions that incorporate pain management may be important for improving health outcomes in patients living with HIV infection.     

Chest pain without established ischaemic heart disease in primary care patients: associated comorbidities and mortality

Background

Ischaemic heart disease (IHD) can be excluded in the majority of patients with unspecific chest pain. The remainder have what is generally referred to as non-cardiac chest pain, which has been associated with gastrointestinal, neuromusculoskeletal, pulmonary, and psychiatric causes.

Aim

To assess morbidity and mortality following a new diagnosis of non-specific chest pain in patients without established IHD.

Design of study

Population-based cohort study with nested case-control analysis.

Setting

UK primary care practices contributing to the General Practice Research Database.

Method

Patients aged 20–79 years with chest pain who had had no chest pain consultation before 2000 and no IHD diagnosis before 2000 or within 2 weeks after the index date were selected from the General Practice Research Database. The selected 3028 patients and matched controls were followed-up for 1 year.

Results

The incidence of chest pain in patients without established IHD was 12.7 per 1000 person-years. In the year following the index date, patients who had chest pain but did not have established IHD were more likely than controls to receive a first IHD diagnosis (hazard ratio [HR] = 18.2, 95% confidence interval [CI] = 11.6 to 28.6) or to die (HR = 2.3, 95% CI = 1.3 to 4.1). Patients with chest pain commonly had a history of gastro-oesophageal reflux disease (GORD; odds ratio [OR] = 2.0, 95% CI = 1.5 to 2.7) or went on to be diagnosed with GORD (risk ratio 4.5, 95% CI = 3.1 to 6.4).

Conclusion

Patients with chest pain but without established IHD were found to have an increased risk of being diagnosed with IHD. Chest pain in patients without established IHD was also commonly associated with GORD.     

Pet-keeping in childhood and adult asthma and hay fever: European community respiratory health survey

BACKGROUND: Whether pet-keeping early in life protects against or promotes allergy remains unclear. OBJECTIVE: Our aim was to examine the effects of childhood pet-keeping on adult allergic disease in a large international population-based study, including information on sensitization, adult pet-keeping, and pet prevalence in the populations. METHODS: We used information from structured interviews (n = 18,530) and specific IgE to common aeroallergens in blood samples (n = 13,932) from participants in the European Community Respiratory Health Survey (ECRHS) to analyze the associations between keeping pets and adult asthma and hay fever. RESULTS: Keeping cats in childhood was associated with asthma only among atopic subjects, an association that varied between centers (P =.002) and was stronger where cats where less common (< 40% cats: odds ratio(wheeze) [OR(wheeze)] = 1.84, 95% CI = 1.31-2.57; 40%-60% cats: OR(wheeze) = 1.33, 95% CI = 1.10-1.61; > or =60% cats: OR(wheeze) = 0.98, 95% CI = 0.73-1.33). Dogs owned in childhood or adulthood were associated with asthma among nonatopic subjects (childhood: OR(wheeze) = 1.28, 95% CI = 1.13-1.46; adulthood: OR(wheeze) = 1.31, 95% CI = 1.14-1.51; both: OR(wheeze) = 1.69, 95% CI = 1.40-2.04). In atopic subjects, those who had owned dogs in childhood had less hay fever (OR = 0.85; 95% CI = 0.73-0.98) and no increased risk of asthma (OR(wheeze) = 1.01, 95% CI = 0.87-1.17). Respiratory symptoms were more common in subjects who had owned birds during childhood (OR(wheeze) = 1.12; 95% CI = 1.02-1.23) independent of sensitization. CONCLUSIONS: The effects of pet-keeping in childhood varied according to the type of pet, the allergic sensitization of the individual, and the wider environmental exposure to allergen. Cats owned in childhood were associated with more asthma in sensitized adults who grew up in areas with a low community prevalence of cats. Dogs owned in childhood seemed to protect against adult allergic disease but promote nonallergic asthma.     

The association of early life exposure to antibiotics and the development of asthma,eczema and atopy in a birth cohort: confounding or causality?

Background In general, studies reporting positive associations between antibiotic exposure and respiratory and allergic disease have been unable to determine the nature of this association.
Objective To examine the association between antibiotic exposure in infancy and the development of asthma, eczema and atopy in early childhood.
Methods In a birth cohort study, we collected reported antibiotic exposure before 3 months and before 15 months along with outcomes (wheeze, asthma, eczema, rash, inhaler use) at 15 months ( n =1011) and 4 years ( n =986). Atopy was measured using skin prick tests at 15 months.
Results We found significant univariate associations of antibiotic exposure before 3 months with asthma developing between birth and 15 months [OR 2.32 (95% CI 1.45–3.69)]. After adjustment for chest infections, this association reduced (OR=1.58, 95% CI 0.96–2.60) becoming marginally significant ( P =0.07). A marginally significant association of antibiotics with atopy (OR=1.44, 95% CI 0.96–2.14) in the univariate analysis also reduced after adjustment for chest infections (OR=1.36, 95% CI 0.91–2.05). There was no effect of antibiotic exposure before 15 months on asthma developing after 15 months and present between 3 and 4 years (OR=1.35 95% CI 0.85–2.14). Antibiotic exposure before 3 months was not associated with eczema and rash developing between birth and 15 months but exposure before 15 months was related to eczema [OR 1.83 (95% CI 1.10–3.05)] and rash [OR 1.61 (95% CI 1.02–2.53)] developing after 15 months and remaining present at 4 years. These effects reduced in the multivariate analysis.
Conclusions Our findings suggest that the effect of antibiotics on respiratory disease may be due to confounding by chest infections at an early age when asthma may be indistinguishable from infection.
