Chlamydia pneumoniae infections in patients with community-acquired pneumonia in Slovenia

It is well known that Chlamydia pneumoniae is an important respiratory pathogen. In this study, the prevalence of specific antibodies to C. pneumoniae in hospitalized patients with community-acquired pneumonia (943 adult females, 990 adult males and 185 children) was evaluated over a period of 7 y (1993-99). Two serum samples were obtained from all of the patients: 1 on admission and the other 3 weeks later. The specimens were tested for C. pneumoniae IgG, IgM and IgA antibodies by means of a microimmunofluorescence test. Acute infection with C. pneumoniae was determined in 9.4% of females and 13.1% of males. In children and adolescent patients, the microimmunofluorescence test showed recent infection in 8.6% of cases, with the highest prevalence occurring in the 11-15 y age group. The highest prevalence of C. pneumoniae pneumonia was found in 1995 and 1999: 15.4% and 13.6% respectively. The results obtained showed that C. pneumoniae is persistently present in the population of Slovenia.     

Epidemiology and outcomes of ventilator-associated pneumonia in a large US database

OBJECTIVES: To evaluate risk factors for ventilator-associated pneumonia (VAP), as well as its influence on in-hospital mortality, resource utilization, and hospital charges. DESIGN: Retrospective matched cohort study using data from a large US inpatient database. PATIENTS: Patients admitted to an ICU between January 1998 and June 1999 who received mechanical ventilation for > 24 h. MEASUREMENTS: Risk factors for VAP were examined using crude and adjusted odds ratios (AORs). Cases of VAP were matched on duration of mechanical ventilation, severity of illness on admission (predicted mortality), type of admission (medical, surgical, trauma), and age with up to three control subjects. Mortality, resource utilization, and billed hospital charges were then compared between cases and control subjects. RESULTS: Of the 9,080 patients meeting study entry criteria, VAP developed in 842 patients (9.3%). The mean interval between intubation, admission to the ICU, hospital admission, and the identification of VAP was 3.3 days, 4.5 days, and 5.4 days, respectively. Identified independent risk factors for the development of VAP were male gender, trauma admission, and intermediate deciles of underlying illness severity (on admission) [AOR, 1.58, 1.75, and 1.47 to 1.70, respectively]. Patients with VAP were matched with 2,243 control subjects without VAP. Hospital mortality did not differ significantly between cases and matched control subjects (30.5% vs 30.4%, p = 0.713). Nevertheless, patients with VAP had a significantly longer duration of mechanical ventilation (14.3 +/- 15.5 days vs 4.7 +/- 7.0 days, p < 0.001), ICU stay (11.7 +/- 11.0 days vs 5.6 +/- 6.1 days, p < 0.001), and hospital stay (25.5 +/- 22.8 days vs 14.0 +/- 14.6 days, p < 0.001). Development of VAP was also associated with an increase of > $40,000 USD in mean hospital charges per patient ($104,983 USD +/- $91,080 USD vs $63,689 USD+/- $75,030 USD, p < 0.001). CONCLUSIONS: This retrospective matched cohort study, the largest of its kind, demonstrates that VAP is a common nosocomial infection that is associated with poor clinical and economic outcomes. While strategies to prevent the occurrence of VAP may not reduce mortality, they may yield other important benefits to patients, their families, and hospital systems.     

Does Social Support Predict Pregnant Mothers’ Information Seeking Behaviors on an Educational Website?

We examine how social support (perceived support and support from a spouse, or committed partner) may influence pregnant women’s information seeking behaviors on a pregnancy website. We assess information seeking behavior among participants in a trial testing the effectiveness of a web-based intervention for appropriate gestational weight gain. Participants were pregnant women (N = 1,329) recruited from clinics and private practices in one county in the Northeast United States. We used logistic regression models to estimate the likelihood of viewing articles, blogs, frequently asked questions (FAQs), and resources on the website as a function of perceived social support, and support from a spouse or relationship partner. All models included socio-demographic controls (income, education, number of adults and children living at home, home Internet use, and race/ethnicity). Compared to single women, women who were married or in a committed relationship were more likely to information seek online by viewing articles (OR 1.95, 95 % CI [1.26–3.03]), FAQs (OR 1.64 [1.00–2.67]), and blogs (OR 1.88 [1.24–2.85]). Women who felt loved and valued (affective support) were more likely to seek information by viewing articles on the website (OR 1.19 [1.00–1.42]). While the Internet provides a space for people who have less social support to access health information, findings from this study suggest that for pregnant women, women who already had social support were most likely to seek information online. This finding has important implications for designing online systems and content to encourage pregnant women with fewer support resources to engage with content.     

Remission criteria and activity indices in psoriatic arthritis

Remission criteria and activity indices used in rheumatoid arthritis (RA) are often applied in psoriatic arthritis (PsA). Some new indices have been specifically developed for PsA. Our objective was to evaluate the performance of different remission criteria and activity indices in PsA. This is a cross-sectional study that includes consecutive patients with PsA. Information necessary to complete the following indices was captured: Composite Psoriatic Disease Activity Index (CPDAI), Psoriatic Arthritis Screening and Evaluation (PASE), Disease Activity Index for Psoriatic Arthritis (DAPSA), Disease Activity Score in 28 Joints (DAS28), Simplified Disease Activity Index (SDAI), Clinical Disease Activity Index (CDAI), and American College of Rheumatology and European League Against Rheumatism (ACR/EULAR) Boolean RA remission criteria. Patients were classified according to activity categories (remission, low, medium, or high disease activity). Correlation between indices was established. Fifty-five patients were included. Mean age was 53 years (SD?=?12), and 35 (63.6 %) were males. Mean PsA disease duration was 5.9 years (SD?=?8.5), and mean psoriasis duration was 15.9 (SD?=?12.6). We found important differences in the percentage of patients classified as in remission by applying different remission criteria: DAS28?=?33 % (95 % confidence interval (CI) 20–45) vs ACR/EULAR?=?4 % (95 % CI 1–17). Particularly, DAS28 and minimal disease activity seemed to be less stringent in PsA than the other indices. Of the specific PsA indices evaluated, CPDAI showed the poorest correlation with all the other activity measurements, although differences were not statistically significant in most cases. Disease activity in PsA is measured by many different indices. In spite they all showed good correlations between them, they classified different patients in different disease status.     

Healthy Functioning in Families with a Schizophrenic Parent

This is a study using Family Adaptability and Cohesion Evaluation Scales (FACES IV) that surveyed married couples with children where one person was schizophrenic. A surprising finding was that both the patient and their partner rated their family in the healthy range. Using the Circumplex Model where balanced scores are healthy, most of the patients (78%) and spouses (87%) described their family as balanced. Both groups saw their family as “flexible to very flexible” and “connected to very connected.” In terms of the unbalanced aspects of their family (disengaged, enmeshed, rigid, and chaotic), the vast majority of patients and spouses rated these traits as low or very low. Both the patients and spouses described the family communication as more negative than positive. In terms of family satisfaction, it was low for over half of the patients and partners. In summary, these families with a schizophrenic parents generally were functioning well in spite of this major disorder in one parent.     

Mid-term Results of Laparoscopic Sleeve Gastrectomy and Roux-en-Y Gastric Bypass in Adolescent Patients

The prevalence and severity of obesity in children and adolescents has been increasing in recent years at an unprecedented rate. Morbidly obese children will almost certainly develop severe comorbidities as they progress to adulthood, and bariatric surgery may provide the only alternative for achieving a healthy weight. The aim of this study was to assess the long-term outcomes and safety of laparoscopic sleeve gastrectomy (LSG) and Roux-en-Y gastric bypass (RYGB) as new treatment modalities for morbidly obese adolescents. We conducted a retrospective review of a prospectively collected database of all adolescent patients who underwent LSG and RYGB under IRB protocol at the Bariatric and Metabolic Institute in Cleveland Clinic Florida between 2002 and 2011. Patients were also contacted by phone, adhering to HIPAA regulations, and were asked to answer a survey. Eighteen adolescents had a bariatric procedure performed at this institution. The mean age was 17.5 years, the average weight was 293.1 lbs, and the average BMI was 47.2 kg/m². The mean follow-up period consisted of 55.2 months. The postoperative weight at 55 months follow-up was 188.4 lbs and average BMI was 30.1 kg/m². Fifteen of the patients were available for follow-up. Thirteen out of 16 (81 %) comorbidities in patients available for follow-up were in remission following rapid weight loss. The long-term follow-up and perioperative morbidity shown in this study suggest that LSG and LRYGB appear to be safe and effective operations in morbidly obese adolescents.
