Reduced Serum Levels of Bone Formation Marker P1NP in Psoriasis

Psoriasis is a chronic inflammatory disease of the skin and joints. More recent data emphasize an association with dysregulated glucose and fatty acid metabolism, obesity, elevated blood pressure and cardiac disease, summarized as metabolic syndrome. TNF-a and IL-17, central players in the pathogenesis of psoriasis, are known to impair bone formation. Therefore, the relation between psoriasis and bone metabolism parameters was investigated. Two serum markers of either bone formation—N-terminal propeptide of type I procollagen (P1NP) or bone resorption—C-terminal telopeptide of type I collagen (CTX-I)—were analyzed in a cohort of patients with psoriasis vulgaris. In patients with psoriasis, P1NP serum levels were reduced compared to gender-, age-, and body mass index-matched healthy controls. CTX-I levels were indistinguishable between patients with psoriasis and controls. Consistently, induction of psoriasis-like skin inflammation in mice decreases bone volume and activity of osteoblasts. Moreover, efficient anti-psoriatic treatment improved psoriasis severity, but did not reverse decreased P1NP level suggesting that independent of efficient skin treatment psoriasis did affect bone metabolism and might favor the development of osteoporosis. Taken together, evidence is provided that bone metabolism might be affected by psoriatic inflammation, which may have consequences for future patient counseling and disease monitoring

Nurses’ experiences of a screening and associated psychosomatic consultation service for mental comorbidities in somatic care inpatients – a qualitative study

BackgroundScreening for mental comorbidities and related liaison service can reduce hospital length of stay in somatic hospital care. To develop, test and sustain such health care services, stakeholder feedback is required. One of the most important stakeholders in general hospital care and health care processes are nurses.AimThe aim of this study is to explore nurses’ experiencess on standardized nurse-led screening for mental comorbidities and associated psychosomatic consultation service in routine somatic inpatient care.MethodSemi-structured qualitative interviews were conducted with 18 nurses that were involved in a nurse-led screening service for mental comorbidities on internal medicine or dermatological wards. Data were analyzed using thematic analysis.ResultsEight thematic groups were developed. On the one hand, participants reported benefits of screening: mental health education, general mental health awareness, holistic treatment approach, opportunity to build rapport with patients and reduction in workload. On the other hand, possible psychological effects of the intervention, reasons why patients may not want to be referred and application requirements to facilitate delivery were identified. None of the nurses opposed screening and associated psychosomatic consultation service.ConclusionAll nurses endorsed the screening intervention and considered it meaningful. Nurses particularly emphasized the potential for holistic patient care and nurses’ improved skills and competencies, but partly critizised current application requirements.Relevance to clinical practiceThis study adds on existent evidence on nurse-led screening for mental comorbidities and associated psychosomatic consultation service by emphasizing its potential to improve both patient care as well as nurses’ perceived self-efficacy and job satisfaction. To take full advantage of this potential, however, usability improvements, regular supervision, and ongoing training for nurses need to be considered

Cardiovascular disease, risk factors and heart rate variability in the elderly general population: Design and objectives of the CARdiovascular disease, Living and Ageing in Halle (CARLA) Study

BACKGROUND: The increasing burden of cardiovascular diseases (CVD) in the ageing population of industrialized nations requires an intensive search for means of reducing this epidemic. In order to improve prevention, detection, therapy and prognosis of cardiovascular diseases on the population level in Eastern Germany, it is necessary to examine reasons for the East-West gradient of CVD morbidity and mortality, potential causal mechanisms and prognostic factors in the elderly. Psychosocial and nutritional factors have previously been discussed as possible causes for the unexplained part of the East-West gradient. A reduced heart rate variability appears to be associated with cardiovascular disease as well as with psychosocial and other cardiovascular risk factors and decreases with age. Nevertheless, there is a lack of population-based data to examine the role of heart rate variability and its interaction with psychosocial and nutritional factors regarding the effect on cardiovascular disease in the ageing population. There also is a paucity of epidemiological data describing the health situation in Eastern Germany. Therefore, we conduct a population-based study to examine the distribution of CVD, heart rate variability and CVD risk factors and their associations in an elderly East German population. This paper describes the design and objectives of the CARLA Study. METHODS/DESIGN: For this study, a random sample of 45–80 year-old inhabitants of the city of Halle (Saale) in Eastern Germany was drawn from the population registry. By the end of the baseline examination (2002–2005), 1750 study participants will have been examined. A multi-step recruitment strategy aims at achieving a 70 % response rate. Detailed information is collected on own and family medical history, socioeconomic, psychosocial, behavioural and biomedical factors. Medical examinations include anthropometric measures, blood pressure of arm and ankle, a 10-second and a 20-minute electrocardiogram, a general physical examination, an echocardiogram, and laboratory analyses of venous blood samples. On 200 participants, a 24-hour electrocardiogram is recorded. A detailed system of quality control ensures high data quality. A follow-up examination is planned. DISCUSSION: This study will help to elucidate pathways to CVD involving autonomic dysfunction and lifestyle factors which might be responsible for the CVD epidemic in some populations
