Awareness of risk factors for coronary heart disease following interventional cardiology procedures: A key concern for nursing practice

Cardiovascular risk factor modification to prevent progression of coronary heart disease is important for patients following percutaneous coronary intervention. The aims of this study were to assess patient's awareness of modifiable cardiac risk factors and examine if patients with modifiable risk factors were more likely to identify these risk as amenable to change. Awareness of risk factors was measured using the Indiana Cardiac Rehabilitation Knowledge Questionnaire in a cohort of prospective, consecutive participants post percutaneous coronary intervention. Completed questionnaires were received from 75% of the participants. The majority were able to identify high cholesterol (87%), smoking (83%) and hypertension (82%) as modifiable risk factors. Less than half (46%) of the respondents identified diabetes as a modifiable risk factor. Only a third of participants recognized all six modifiable risk factors. A large proportion of patients who were smokers, or who had high cholesterol or hypertension, identified these as risk factors. A third of people with documented diabetes did not recognize this condition as a risk factor for heart disease. The findings have important implications for nursing practice in terms of directing educational efforts for the modification of risk factors for coronary heart disease.     

Bench-to-bedside review: The role of glycosaminoglycans in respiratory disease

The extracellular matrix (ECM) plays a significant role in the mechanical behaviour of the lung parenchyma. The ECM is composed of a three-dimensional fibre mesh that is filled with various macromolecules, among which are the glycosaminoglycans (GAGs). GAGs are long, linear and highly charged heterogeneous polysaccharides that are composed of a variable number of repeating disaccharide units. There are two main types of GAGs: nonsulphated GAG (hyaluronic acid) and sulphated GAGs (heparan sulphate and heparin, chondroitin sulphate, dermatan sulphate, and keratan sulphate). With the exception of hyaluronic acid, GAGs are usually covalently attached to a protein core, forming an overall structure that is referred to as proteoglycan. In the lungs, GAGs are distributed in the interstitium, in the sub-epithelial tissue and bronchial walls, and in airway secretions. GAGs have important functions in lung ECM: they regulate hydration and water homeostasis; they maintain structure and function; they modulate the inflammatory response; and they influence tissue repair and remodelling. Given the great diversity of GAG structures and the evidence that GAGs may have a protective effect against injury in various respiratory diseases, an understanding of changes in GAG expression that occur in disease may lead to opportunities to develop innovative and selective therapies in the future.     

Efficacy and safety of cryotherapy vs. trichloroacetic acid in the treatment of solar lentigo

Background Solar lentigines are common sun‐induced benign melanocytic proliferation that presents a significant cosmetic worrying for many middle‐aged and elderly patients. Although the newer photoselective lasers have become the mainstay of treatment, cryotherapy and trichloroacetic acid (TCA) solution are inexpensive alternatives in the treatment of solar lentigines. The purpose of this study was to assess the efficacy of cryotherapy compared with TCA 33% on solar lentigines of the back of the hands (SLBH) in patients presenting to dermatologic clinic of our hospital. Methods Each hand of 25 women with SLBH was treated randomly with either cryotherapy or TCA 33% solution. Photographs of the hands were taken prior to and 2 months following the treatment. The response and side‐ effect rate were compared. Results Cryotherapy was more likely to produce substantial lightening of the solar lentigines than TCA 33% solution (P = 0.025) but more painful and took more time to heal. Post‐inflammatory hyperpigmentation (PIH) was almost equal in two types of treatment (P > 0.05). Statistically, the better results were seen in fairer Fitzpatrick's skin types (P = 0.00). Conclusion Cryotherapy shows better results than TCA 33% solution in the treatment of SLBH particularly in lower Fitzpatrick skin types. PIH is the major complication of each type of treatments particularly in darker Fitzpatrick skin types. Generally, the major criterion for treatment of SLBH with cryotherapy or TCA is Fitzpatrick's skin type of patients.     

Subcision in acne scar with and without subdermal implant: a clinical trial

Background Subcision is a procedure that has been reported to be beneficial in treatment of acne scars. Objective This stady aims to assess the efficacy of subcision in the treatment of rolling acne scars and evaluate a novel subdermal filler ‘absorbable plain catgut suture’ with subcision. Methods Twenty‐two patients with rolling acne scars underwent subcision, 20 of whom completed treatment and follow‐up period. One side of the face underwent subcision and another side subcision with subdermal implant. The patients and investigators’ assessment of improvement were both recorded. Results Subcision showed mild improvement in about 60% of patient and moderate improvement in about 40% of them. The rate of response showed no significant difference with the use of subdermal implant. The side‐effects of local oedema, bruising and infection were all transient. Conclusions Subcision seems to be a safe method to correct the rolling acne scars with long‐term improvement. However, the subdermal implant led to no significant superior results.     

Women''s expectations and experiences of childbirth

OBJECTIVE: to explore, describe and understand the expectations during pregnancy and subsequent experiences of childbirth in primiparae. DESIGN: a qualitative study using a phenomenological approach. Data were collected using unstructured, tape-recorded interviews in late pregnancy and at two weeks post birth. SETTING: the north of England. PARTICIPANTS: eight pregnant women, expecting their first baby. FINDINGS: the women all wanted to take an active part in their labour and the feeling of being 'in control' was the main finding and the 'essence' of this study. This was achieved through support from partners, the positive attitudes of the midwives caring for them during pregnancy and labour, information giving during pregnancy and labour and being able to make and be included in decision making during labour. IMPLICATIONS FOR PRACTICE: if women are to be empowered by making choices for childbirth and feeling 'in control', then it is important for midwives to explore and discover the wishes and feelings of women in their care so that realistic expectations can be promoted and then hopefully fulfilled.
