BACKGROUND Chronic obstructive pulmonary disease (COPD) affects 14 to 20 million Americans and is associated with increased prevalence of affective disorders, contributing significantly to disability. This study compared cognitive behavioral therapy (CBT) group treatment for anxiety and depression with COPD education for COPD patients with moderate-to-severe anxiety and/or depressive symptoms. METHOD A randomized controlled trial (RCT) was conducted between 11 July 2002 and 30 April 2005 at the Michael E. DeBakey VA Medical Center, Houston, TX. Participants were 238 patients treated for COPD the year before, with forced expiratory value in 1 second (FEV)1/forced vital capacity (FVC)<70% and FEV1<70% predicted, and symptoms of moderate anxiety and/or moderate depression, who were being treated by a primary care provider or pulmonologist. Participants attended eight sessions of CBT or COPD education. Assessments were at baseline, at 4 and 8 weeks, and 4, 8 and 12 months. Primary outcomes were disease-specific and generic quality of life (QoL) [Chronic Respiratory Questionnaire (CRQ) and Medical Outcomes Survey Short Form-36 (SF-36) respectively]. Secondary outcomes were anxiety [Beck Anxiety Inventory (BAI)], depressive symptoms [Beck Depression Inventory-II (BDI-II)], 6-minute walk distance (6MWD) and use of health services. RESULTS Both treatments significantly improved QoL, anxiety and depression (p<0.005) over 8 weeks; the rate of change did not differ between groups. Improvements were maintained with no significant change during follow-up. Ratios of post- to pretreatment use of health services were equal to 1 for both groups. CONCLUSIONS CBT group treatment and COPD education can achieve sustainable improvements in QoL for COPD patients experiencing moderate-to-severe symptoms of depression or anxiety.

Serum CagA antibodies in asymptomatic subjects and patients with peptic ulcer: lack of correlation of IgG antibody in patients with peptic ulcer or asymptomatic Helicobacter pylori gastritis.

AIM/BACKGROUND: Several studies have suggested that Helicobacter pylori which express CagA may be more virulent than those that do not, but limited populations have been studied to date. The aim of this study was to confirm and extend the association of CagA positive H pylori strains in a different geographical area and to a large, well defined patient population. METHOD: A validated ELISA for serum IgG to CagA was used to investigate the prevalence of CagA seropositivity in 100 patients with peptic ulcer compared with 77 with H pylori infection without ulcer disease in a North American population. The extent of antral and corpus inflammation and H pylori density in relation to CagA seropositivity in 40 subjects with H pylori infection were assessed semiquanitatively. All studies were carried out in a coded and blinded manner. RESULTS: The prevalence of serum IgG CagA antibodies was higher in H pylori infected patients with ulcer (59%) compared with healthy H pylori infected volunteers (44%), but the difference was not significant. In contrast, the titre of serum IgG anti-CagA antibodies was higher among the seropositive subjects without ulcer disease, but again the difference was not significant. Comparison of histological features between asymptomatic individuals with H pylori infection in relation to CagA IgG antibody status revealed no differences in infiltration with acute inflammatory cells, H pylori density, or gastritis index. There was no relation evident between the degree of polymorphonuclear cell infiltration and the serum IgG antibody titre to CagA. Mononuclear cell infiltration in the antrum, but not the corpus, was greater in those with CagA IgG compared with those without (median score 5 v 3). CONCLUSIONS: A right association between the presence or titre of serum IgG to CagA and peptic ulcer disease, greater H pylori density or infiltration of the mucosa with acute inflammatory cells could not confirmed in a North American population. Perhaps geographical differences in the prevalence of circulating H pylori strains are responsible for the discrepant results reported.

The factors influencing the acquisition and prevalence of Helicobacter pylori infection remain incompletely understood. In Russia, the demographic and socioeconomic factors are relatively similar, allowing investigation of risk factors that might not be identifiable in a more diverse population.

Objectives: In an aging population, the number of veterans diagnosed with dementia is likely to increase. Knowledge of existing dementia prevalence will be beneficial in planning for future patient care needs. Our objectives were to assess the prevalence of the dementia diagnosis among those treated at Veterans Affairs (VA) medical centers and determine how it varies across race and Veterans Integrated Service Network (VISN). Materials and Methods: Data were collected on all veterans seen within the VA medical system from 1997 through the first half of 2001. Only veterans aged 65 and over were included in the study. Veterans were included if they had one of the following dementia ICD-9 codes: 290.XX, 291.2, 294.XX, 331.XX, 046.1, or 046.3. Results: The overall prevalence of dementia was 7.3%. The prevalence of dementia was similar among white patients and patients of other races, except African-American patients, in whom it was 50% higher. Across VISNs, the prevalence of dementia ranged from 5.8 to 9.4%. Alzheimer’s disease was the most frequently diagnosed type of dementia within the VA, and inpatient service utilization and outpatient psychiatry visits by individuals with dementia were high relative to other VA patients. Discussion: The overall prevalence identified is consistent with that reported in the literature, as is the elevated prevalence in African-Americans versus whites. The data on prevalence by VISN may identify regional variation in either the types of dementia present or the diagnostic criteria used. The dementia diagnosis is clearly associated with substantial service use.

Objective: This study examined factors affecting deficit awareness (DA) and the effects of diagnostic status (dementia and depression), measurement method and DA dimension on these relationships. Methods: One hundred and twenty-one participants (66 persons with dementia and 55 persons without dementia, matched for depression diagnosis) were enrolled, each with a family informant. Participant DA (clinician and informant rated), cognitive impairment, physical illness, functional disability and caregiver burden were assessed. Results: Factors affecting DA included presence of dementia, presence of depression, cognitive impairment, caregiver burden, and functional disability. The relationship between these factors and DA varied by DA dimension. Conclusions: DA measurement method was an important moderating variable; clinicians may be better at evaluating cognitive DA whereas informants may be better at evaluating functional and emotional/behavioral DA.

Aggression is often associated with dementia. In this study, aggression in veterans newly diagnosed with dementia was examined and characterized. Participants were ≥60 years diagnosed with dementia at the Michael E. DeBakey Veterans Affairs Medical Center in Houston, Texas, from 2001 to 2004. Aggression was defined as a positive caregiver response to 1 or more of 3 probes from the Ryden Aggression Scale, administered during a telephone screen. Of 1276 contacts, 385 (30%) were eligible and agreed to participate; at initial screening, 75 (19.5%) were aggressive (23 [31%] verbally, 9 [12%] physically, 24 [32%] verbally and physically, and 19 [25%] with unspecified aggression). The surprisingly high prevalence of aggression in individuals newly diagnosed with dementia suggests the potential usefulness of early screening for aggression in this population.
