Levels of filaggrin degradation products are influenced by both filaggrin genotype and atopic dermatitis severity

Background:

Filaggrin, coded by FLG, is the main source of several major components of natural moisturizing factor (NMF) in the stratum corneum (SC), including pyrrolidone carboxylic acid (PCA) and urocanic acid (UCA). Loss-offunction mutations in FLG lead to reduced levels of filaggrin degradation products in the SC. It has recently been suggested that expression of filaggrin may additionally be influenced by the atopic inflammatory response. In this study, we investigated the levels of several breakdown products of filaggrin in the SC in healthy controls (CTRL) and patients with atopic dermatitis (AD) in relation to FLG null allele status. We examined the relationship between NMF (defined here as the sum of PCA and UCA) and AD severity.

Methods:

The SC levels of filaggrin degradation products including PCA, UCA, histidine (HIS) and tyrosine were determined in 24 CTRL and 96 patients with moderate-to-severe AD. All subjects were screened for 11 FLG mutations relevant for the study population.

Results:

The levels of PCA, UCA and HIS correlated with FLG genotype. Furthermore, these levels were higher in the CTRL when compared to AD patients with no FLG mutations. Multiple regression analysis showed that NMF levels were independently associated with FLG genotype and severity of disease.

Conclusion:

Decreased NMF is a global feature of moderate-to-severe AD; within AD, FLG genotype is the major determinant of NMF, with disease severity as a secondary modifier. NMF components are reliably determined by a noninvasive and relatively inexpensive tape stripping technique.

The case for graduate entry to the United Kingdom nursing register

AIM

The recent decision of the United Kingdom Nursing and Midwifery Council to make nursing a degree profession is contentious and has generated debate among nurses and other stakeholders. We argue why nurses need a degree to nurse and what the implications of making a degree in nursing obligatory at the point of registration will be.

BACKGROUND

Nurses work at the forefront of any healthcare system. The complexity of their role and demands on them are increasing. To fulfil demands and expectations of employers, the public and the profession, and to be able to work collaboratively with other healthcare professions, nurses need critical thinking, problem-solving and decision-making skills, which can help them to work as independent practitioners. We argue that this can only be assured if the level of education for nurses is raised from diploma to degree, making this a prerequisite for registration as a nurse.

CONCLUSIONS

The increasingly complex role of nurses, the changing landscape of the healthcare needs and a need to improve the image and status of nursing as a profession to make it an attractive career choice are some of the important reasons that justify nursing in becoming a degree-only profession.

Increasing the confidence of nursing staff to address the sexual health needs of people living with HIV: the use of motivational interviewing

The need to promote safer sexual behaviour has taken on new urgency in the UK because of large increases in the number of sexually transmitted infections (STIs). The sexual health needs of people living with HIV and AIDS (PLHA) also require attention as part of health promotion efforts. Many sexual health clinics are however struggling with high demand and limited resources. Within this context, this paper describes an innovate attempt at STI prevention with PLHA. Specifically, nursing staff were trained in the use of motivational interviewing to address sexual health issues and safer sexual behaviour in PLHA. We describe the training package and the impact upon participants. We conclude that by providing a positive training experience, front-line health staff that see the highest volume of PLHA with repeat STIs, can be assisted in developing their skills and confidence in prevention work with clients.

Mokken scaling and principal components analyses of the CORE-OM in a large clinical sample

In a sample of 543 adult National Health Service (NHS) patients referred to a Psychological Therapies Service, the responses to the Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM) self-report questionnaire were examined using conventional principal components analysis (PCA) and a unique application of Mokken Scaling Procedure (MSP). Following the theoretical views of G. A. Foulds, it was suggested that some items more properly belong to the universe of attitudes and traits rather than that of symptoms and states. Accordingly, the analyses were carried out both with and without the CORE-OM Risk domain items. Both PCAs produced a very large first component of Psychological distress, while the small second component differs. With all items included, the second component was of Risk. With the risk items excluded, the second component was now Functioning. The MSP results, respectively, were of a five-item scale of Functioning (impaired by depression) and on the second analysis, a five-item Functioning scale (impaired by anxiety). There was discussion on the criteria for item selection, the time scale specified in questionnaire instructions and the optimum number of items required for a symptom scale. It was concluded that the CORE-OM item pool did not conform to its purported face validity domains and subdomains, but predominantly constitutes a large Psychological distress scale with considerable item redundancy.
