Psychological distress among survivors of esophageal cancer: the role of illness cognitions and coping

Leventhal's common sense model has provided a useful framework for explaining psychological distress in several chronic illnesses. The model indicates that a person's perception of their illness and their coping strategies are the key determinants of their experience of psychological distress. The present research examines whether illness perceptions and coping strategies are related to levels of psychological distress among survivors of esophageal cancer. Everyone registered with the Oesophageal Patients' Association in the UK was mailed a questionnaire booklet, which included the Illness Perception Questionnaire-Revised, the Cancer Coping Questionnaire, and the Hospital Anxiety and Depression Scale. Complete responses were received from 484 people. Regression models indicated that the variables measured could explain 51% of the variance in anxiety and 42% of the variance in depression. Perceptions of esophageal cancer explained the majority of this variance. Positive focus coping strategies were also found to be important in explaining psychological distress. The results of this study are consistent with previous research demonstrating that illness perceptions are stronger correlates of adaptive outcomes than coping strategies. The findings suggest that cognition-based interventions could potentially be most effective in minimizing emotional distress among survivors of esophageal cancer.

Adjustment in children with intractable epilepsy:importance of seizure duration and family factors

Seventy-five families of children with intractable epilepsy but without a severe learning disability (mean age 7 years 1 month, SD 2 years 6 months; range 2 to 12 years) who attended a regional paediatric neurology service, were surveyed. A postal questionnaire was used which included standardized measures of child and family adjustment; forty-eight families responded (64%; 31 males, 17 females). There was no significant difference between responders and non-responders in terms of age, sex, number of other chronic illnesses and disabilities, age at epilepsy diagnosis, seizure type, nor number of antiepileptic drugs currently prescribed (p > 0.05). The importance of including multidimensional measures of outcome was highlighted by the finding that epilepsy, pharmacological, and psychosocial factors were differentially associated with specific adjustment difficulties. Two factors appeared to be most pervasively implicated across a range of adjustment problems: frequency of rectal diazepam administration and family patterns of relating to each other (p <0.05). It appeared that duration of seizures (as indicated by frequency of rectal diazepam administration), rather than the frequency of seizures per se, was more pernicious in terms of poor adjustment. Intrafamilial relations (degree of conflict/cohesion and soon) were not only associated with adjustment difficulties in the child, but also with the frequency of seizures themselves. Implications for psychological interventions in intractable epilepsy in childhood are highlighted.

Medication use review in Qatar: Are community pharmacists prepared for the extended professional role?

Background
The incidence of chronic illnesses is increasing globally. Non-adherence to medications and other medication-related problems are common among patients receiving long-term medications. Medication use review (MUR) is a service provision with an accredited pharmacist undertaking structured, adherence-centered reviews with patients receiving multiple medications. MUR services are not yet available in community pharmacies in Qatar.

Objective
The current study aims to evaluate community pharmacists' knowledge, attitudes, and perception towards establishing MUR as an extended role in patient care.

Setting
Private community pharmacies in Qatar including chains and independent pharmacies.

Methodology
A cross-sectional survey using a self-administered questionnaire was conducted among licensed community pharmacists from December 2012 to January 2013. Data analysis was conducted using descriptive and inferential statistics.

Main outcome measures
Knowledge, attitudes, and practices related to MUR concept and services.

Results A total of 123 participants responded to the survey (response rate 56 %). The mean total knowledge score was 71.4 ± 14.7 %. An overwhelming proportion of the participants (97 %) were able to identify the scope of MUR in relation to chronic illnesses and at enhancing the quality of pharmaceutical care. Furthermore, 80 % of the respondents were able to identify patients of priority for inclusion in an MUR program. However, only 43 % of the participants knew that acute medical conditions were not the principal focus of an MUR service, while at least 97 % acknowledged that the provision of MUR services is a great opportunity for an extended role of community pharmacists and that MUR makes excellent use of the pharmacist's professional skills in the community. The participants generally reported concerns about time, dedicated consultation area, and support staff as significant barriers towards MUR implementation.

Conclusion
This study suggests that community pharmacists in Qatar had sufficient knowledge about the concept of MUR and its scope, but there were still important deficiencies that warrant further education. The findings have important implications on policy and practice pertaining to the implementation of MUR as an extended role of pharmacists and as part of Qatar's National Health Strategy to move primary health care forward.

Is there an association between angiotensin-converting enzyme gene variants and chronic nonproductive cough?

Background: It is unclear why some patients develop a chronic nonproductive cough. Angiotensin-converting enzyme (ACE) inactivates tussive peptides in the airways such as bradykinin and tachykinins. An insertion/deletion polymorphism in the ACE gene accounts for variation in ACE levels, and patients with the II genotype have lowest serum ACE levels compared with ID and DD genotypes. We hypothesized that the II genotype would be associated with increased risk of developing a chronic cough.

Materials and methods: We recruited 47 patients (33 women), referred for evaluation of cough (median cough duration, 24 months; range, 2 to 240 months). Cough patients were evaluated using a comprehensive diagnostic protocol, and cough reflex sensitivity was measured using a capsaicin inhalation challenge. ACE genotyping was performed on DNA samples from patients using the polymerase chain reaction followed by agarose gel electrophoresis. ACE genotypes in patients with chronic cough were compared with those in 199 healthy control subjects. Serum ACE levels were determined using a colorimetric assay.

Results: Genotype frequencies for the ACE gene were similar between patients and control subjects. There was no correlation between capsaicin sensitivity and ACE genotypes or serum ACE levels.

Conclusion: Susceptibility to develop chronic cough is not associated with ACE genotype.

Elective versus symptomatic antibiotic treatment in cystic fibrosis patients with chronic Pseudomonas infection of the lungs

BACKGROUND:
A previous retrospective study suggested that a policy of regular anti-pseudomonal antibiotic treatment improved pulmonary function and increased survival in patients with cystic fibrosis chronically infected with Pseudomonas species. The results of a prospective multicentre study to compare the effects on pulmonary function and mortality of three monthly elective anti-pseudomonal antibiotic treatment with conventional symptomatic treatment are reported.

METHODS:
Sixty patients with cystic fibrosis, chronically infected with P aeruginosa, were randomised to the two treatment arms (elective or symptomatic) and followed clinically at yearly reviews. The major end points were changes in forced expiratory volume in one second (FEV(1)) and forced vital capacity (FVC). Survival was a secondary end point.

RESULTS:
Patients in the symptomatic group received a mean of three antibiotic treatments each year and those in the elective group received four antibiotic treatments during each year of the study. No significant differences in FEV(1) and FVC were found between the two groups after three years. There was a statistically non-significant higher rate of deaths in the elective group (n = 4), three of which were associated with B cepacia infection, compared with the symptomatic group (n = 0).

CONCLUSIONS:
This study did not demonstrate an advantage of a policy of elective antibiotic treatment over symptomatic treatment in patients with cystic fibrosis chronically infected with Pseudomonas species.

Oxidative stress in lavage fluid of preterm infants at risk of chronic lung disease

There is evidence that oxidative stress plays a role in the development of chronic lung disease (CLD), with immature lungs being particularly sensitive to the injurious effect of oxygen and mechanical ventilation. We analyzed total ascorbate, urate, and protein carbonyls in 102 bronchoalveolar lavage fluid samples from 38 babies (33 preterm, 24–36 wk gestation; 5 term, 37–39 wk gestation). Preterm babies had significantly decreasing concentrations of ascorbate, urate, and protein carbonyls during the first 9 days of life (days 1–3, 4–6, and 7–9, Kruskal-Wallis ANOVA: P 5 0.016, P , 0.0001, and P 5 0.010, respectively). Preterm babies had significantly higher protein carbonyl concentrations at days 1–3 and 4–6 (P 5 0.005 and P 5 0.044) compared with term babies. Very preterm babies (24–28 wk gestation) had increased concentrations of protein carbonyls at days 4–6 (P 5 0.056) and significantly decreased ascorbate concentrations at days 4–6 (P 5 0.004) compared with preterm babies (29–36 wk gestation). Urate concentrations were significantly elevated at days 1–3 (P 5 0.023) in preterm babies who subsequently developed CLD. This study has shown the presence of oxidative stress in the lungs of preterm babies during ventilation, especially in those who subsequently developed CLD.
