The long-term impact of eGFR reporting on referral patterns

BACKGROUND

The prognostic significance of CKD has driven the widespread introduction of automated estimated glomerular filtration rate (eGFR) reporting, and the incorporation of CKD in the revised Quality Outcomes Framework (QOF) of the General Medical Services (GMS) contract in the U.K.

AIMS

To assess the long-term impact of the introduction of these two initiatives, on patient referral numbers to a nephrology service.

METHODS

Data was collected on the numbers and basic characteristics of all new patients referred from April 2005 to March 2011, to one NHS Health Board.

RESULTS

Introduction of eGFR reporting and CKD QOF domains was associated with a significant increase in the number of referrals, which was sustained. The initiatives also led to a sustained increase in the mean age of the patients at referral, predominantly due to an increase in the age of female patients referred. There was also an increase in the proportion of female patients referred. In the immediate aftermath of the introduction of change there was a transient decrease in the average eGFR at referral, a decrease in age of patients referred with an eGFR <15ml/min and an increase in the eGFR of patients >70yrs of age.

CONCLUSIONS

The data demonstrates significant and sustained increase in numbers of referrals. In the short term this was associated with a reduction in referral of elderly patients with stage 5 CKD and an increase in elderly patients with mild renal impairment. In the longer term we saw an increase in referral of an older female population.

Prevalence and risk factors of food insecurity among a cohort of older Australians

OBJECTIVE

With ongoing national concern about food security, the aim of the study was to estimate the prevalence of food insecurity and to identify associated characteristics in a cohort of older Australians.

DESIGN, SETTING AND PARTICIPANTS

The Blue Mountains Eye Study is a cohort study of community living participants aged 49 + years. The 12-item food security survey was completed by 3068 participants in the cross sectional study which comprised 2335 survivors from baseline and the recruitment of an additional 1174 eligible residents.

MAIN OUTCOME MEASURES

Prevalence of self reported food insecurity was calculated and multivariate logistic regression provided odds ratios with 95% confidence intervals to determine risk factors.

RESULTS

Overall prevalence of food insecurity was 13%. Women (15.7%) compared with men (9.4%) and younger participants, aged <70 years (15.7%) than older participants, ≥70 years (8.4%), were significantly more likely to report being food insecure. Characteristics for reporting food insecurity included participants living in rented accommodation (OR 4.10, 95% CI: 2.83, 5.89) and those living on a pension only (OR 1.90, 95%CI: 1.30, 2.78).

CONCLUSIONS

A relatively high level of food insecurity among this representative population of older Australians should be an issue of concern for policy makers and health and welfare service providers. Addressing food insecurity should be a priority of integrated national food and nutrition policies and this should in turn inform health and welfare service provision to this vulnerable population.

Effects of a formal exercise program on Parkinson's disease: a pilot study using a delayed start design

INTRODUCTION

Parkinson's Disease (PD) is a progressive neurodegenerative disease. Increasing evidence shows that physical exercise is beneficial for motor and non-motor symptoms of PD, and animal models suggest that it may help slow progression of disease.

METHODS

Using a randomized delayed-start design, 31 patients were randomized to an early start group (ESG) or a delayed start group (DSG) exercise program. The ESG underwent a rigorous formal group exercise program for 1 h, three days/week, for 48 weeks (November 2011-October 2012). The DSG participated in this identical exercise program from weeks 24-48. Outcome measures included the Unified Parkinson's Disease Rating Scale (UPDRS), Walking Test (get-up-and-go), Tinetti Mobility Test, PDQ-39 Questionnaire, and the Beck Depression Inventory.

RESULTS

There was minimal attrition in this study, with only one patient dropping out. Results did not show improvement in total UPDRS scores with early exercise. At week 48, the mean change from baseline total UPDRS score was 6.33 in the ESG versus 5.13 in the DSG (p = 0.58). However, patients randomized to the ESG scored significantly better on the Beck Depression Inventory, with a mean improvement of 1.07 points relative to those in the DSG (p = 0.04).

CONCLUSIONS

The findings demonstrate that long-term, group exercise programs are feasible in the Parkinson's disease population, with excellent adherence and minimal drop out. While the outcome measures used in our study did not provide strong evidence that exercise has a neuroprotective effect on motor function, earlier participation in a group exercise program had a significant effect on symptoms of depression.

Peyronie's Disease as a Complication of Chronic Graft versus Host Disease

Apart from one report of phimosis, involvement of the penis has not been reported as a complication of chronic GVHD. We report a patient with recurrent chronic GVHD who developed skin discoloration of the penile shaft, together with erectile dysfunction consistent with Peyronie's disease. Histological features were consistent with sclerodermatous change. These features suggest that the penis may be a target organ in chronic GVHD.

Food, nutrition and slimming messages in British women's magazines, 1950-1998

BACKGROUND

The present study examined temporality in the representation of food in two popular British women's magazines between 1950 and 1998.

METHODS

A quantitative content analysis of (i) prevalence of cooking, slimming, nutrition advice in articles; (ii) prevalence of food advertising by food type; and (iii) likelihood of various nutrition and consumer messages in advertising was performed on a sample comprising 200 magazines, with 3045 advertisements and 88 articles.

RESULTS

The prevalence of food advertisements decreased (P < 0.001), whereas food articles increased, across decades (P < 0.001). Cooking tips dominated 1950s food writing (100%), contrasting with miniscule coverage in the 1990s (5%). Slimming advice was not represented in 1950s articles and was most common in 1970s articles (55% of articles). Food advertising for all food types decreased in the 1990s decade. There were greater bread and cereals (P < 0.001), protein foods (P = 0.001) and dairy (P < 0.001) advertising in later decades; advertising for sugar- and fat-rich foods (P < 0.001), condiments and baking ingredients (P < 0.001) and beverages (P < 0.001) was greater in earlier decades. Odds of advertising claims for energy, easy digestion, nourishment, general health, economy, good for family (all P < 0.01), pleased others (P = 0.017) and convenience (P = 0.031) were greater in the 1950s and decreased thereafter. Claims around taste and quality were highest in the 1960s (all P < 0.01). Mineral, additive-free, and protein claims were most likely to be invoked in 1970s advertising (all P < 0.01). Low-fat, low-calorie and fibre claims peaked in the 1980s (all P < 0.01), whereas the odds of specific fat claims was greatest in the 1990s (P = 0.015).

CONCLUSIONS

Representation of food resonated with prevailing food culture but was not always congruent with nutrition policy.

Abstract P3-03-01: 3D mapping of total choline in human breast cancer using high-speed MR spectroscopic imaging at 3T: initial experience during neoadjuvant therapy

OBJECTIVE: To assess the feasibility of quantitative high-speed MR spectroscopic imaging (MRSI) of total Choline (tCho) as an adjunct to dynamic-contrast enhanced MRI to improve lesion characterization and monitor treatment response in patients undergoing neoadjuvant chemotherapy (NAC).

METHODS: Twelve patients with infiltrating ductal carcinoma (Table 1) were studied using a clinical 3T MR scanner (Siemens, Erlangen, Germany) equipped with 8- and 16-channel breast array (Hologic Inc., Bedford, MA). Four patients were studied before NAC. Four patients were studied once during NAC. Two patients were studied before and within 2–7 days of treatment initiation. One of these patients participated in an additional scan after 5 months of treatment. Two additional patients were studied at 3 time points during NAC. Measurements were performed using PRESS prelocalized 3D Proton-Echo-Planar-Spectroscopic-Imaging (PEPSI) using TR/TE=2000ms/135ms, matrix size up to 32×16×8, voxel size = 1cc, and total acquisition time of 10 minutes (including water reference scan). Additional data were collected at TE 60 ms to enhance sensitivity for detecting tCho and J-coupled resonances. TE-averaging (8 steps, DTE: 2.5 ms) was employed to minimize gradient sideband artifacts. Quantification of tCho in reference to tissue water was performed using spectral fitting and relaxation correction.

RESULTS: Strongly elevated tCho with maximum concentration up to 5.3 mmol/kg was measured in 9 patients with enhancing lesions larger than 2 cc volume (Table 2). Decreases in tCho were measured in all four patients who were followed during neoadjuvant chemotherapy. Decreases in tCho were measurable during the first week of neoadjuvant treatment in responders, consistent with previous studies. Our preliminary data also indicate that the combination of concentration and spatial extent of detectable tCho may be the most sensitive marker of treatment response.

Assessment of vitamin D concentration in non-supplemented professional athletes and healthy adults during the winter months in the UK: implications for skeletal muscle function

The current study implemented a two-part design to (1) assess the vitamin D concentration of a large cohort of non-vitamin D supplemented UK-based athletes and 30 age-matched healthy non-athletes and (2) to examine the effects of 5000 IU · day(-1) vitamin D(3) supplementation for 8-weeks on musculoskeletal performance in a placebo controlled trial. Vitamin D concentration was determined as severely deficient if serum 25(OH)D < 12.5 nmol · l(-1), deficient 12.5-30 nmol · l(-1) and inadequate 30-50 nmol · l(-1). We demonstrate that 62% of the athletes (38/61) and 73% of the controls (22/30) exhibited serum total 25(OH)D < 50 nmol · l(-1). Additionally, vitamin D supplementation increased serum total 25(OH)D from baseline (mean ± SD = 29 ± 25 to 103 ± 25 nmol · l(-1), P = 0.0028), whereas the placebo showed no significant change (53 ± 29 to 74 ± 24 nmol · l(-1), P = 0.12). There was a significant increase in 10 m sprint times (P = 0.008) and vertical-jump (P = 0.008) in the vitamin D group whereas the placebo showed no change (P = 0.587 and P = 0.204 respectively). The current data supports previous findings that athletes living at Northerly latitudes (UK = 53° N) exhibit inadequate vitamin D concentrations (<50 nmol · l(-1)). Additionally the data suggests that inadequate vitamin D concentration is detrimental to musculoskeletal performance in athletes. Future studies using larger athletic groups are now warranted.

Utility of bronchoalveolar lavage in the diagnosis of pulmonary infection in children with haematological malignancies

BACKGROUND

Fibre-optic bronchoscopy with bronchoalveolar lavage (BAL) is a safe procedure and is associated with low morbidity and mortality in immunocompromised children. Although many studies have highlighted the advantages of positive BAL results in the diagnosis of pulmonary infections, there have been few reports examining the impact of a negative BAL result on clinical management in immunocompromised children on empiric broad-spectrum antimicrobial therapy.

AIM

The aim of this study was to evaluate BAL in the diagnosis of pulmonary infections in children with haematological malignancies who develop pneumonia unresponsive to empiric antimicrobial therapy, and also to determine whether a negative BAL result contributed to the clinical management of these patients.

MATERIALS AND METHODS

A retrospective review of 44 BAL procedures performed in 33 children with haematological malignancy diagnosed and treated at Our Lady's Children Hospital, Crumlin, Dublin 12, Ireland, over a 10-year period was carried out.

RESULTS

We identified a pathogen causing pneumonia in 24 of 44 BAL procedures (54.5 %). The BAL procedure resulted in modification of antimicrobial treatment after 20 of 24 procedures with positive results (83.3 %) in 16 of 20 patients (80 %). Management was changed after 8 of 20 procedures with negative results (40 %) in 8 of 18 patients (44.4 %). The procedure was well tolerated in all patients.

CONCLUSIONS

Our study supports the use of bronchoscopy with BAL as a diagnostic intervention in this patient population. We consider BAL a safe procedure from which both positive and negative results contribute to the patient's clinical management.

Lifetime and recent DSM and ICD psychiatric comorbidity of inpatients engaging in different eating disorder behaviours

OBJECTIVE

Previous studies investigating psychiatric comorbidity in eating disorder (ED) patients compared groups according to ED diagnoses. The current paper compared groups according to ED behaviours: self-induced vomiting, objective binge eating, excessive exercising, and to body mass index (BMI, kg/m(2)) for selected psychiatric comorbidity using two systems: Diagnostic and Statistical Manual of Mental Disorders - Fourth Edition (DSM-IV) and International Classification of Diseases - Tenth Revision (ICD-10) diagnoses.

METHOD

Two hundred and twenty-six patients admitted for treatment in a specialised Eating Disorders Unit completed the Composite International Diagnostic Interview (CIDI). Lifetime and recent (12 months) psychiatric diagnoses were produced according to DSM-IV and ICD-10. Associations between presence of ED behaviours or BMI and psychiatric comorbidity were investigated.

RESULTS

Eighty-eight percent of patients had a lifetime history (72% recent history) of at least one comorbid diagnosis (regardless of diagnostic system). Agreement between the systems was high for mood (affective) disorders and moderate for anxiety/somatoform disorders. Significantly more patients who vomit had lifetime and recent mood (affective) disorders (DSM-IV and ICD-10). Significantly more 'vomiters' had recent anxiety disorders (DSM-IV) and neurotic, stress-related and somatoform disorders (ICD-10) including post-traumatic stress disorder (PTSD; DSM-IV and ICD-10). More patients with BMI >17.5 kg/m(2) had lifetime and recent mood (affective) disorders and lifetime PTSD (DSM-IV and ICD-10). The results for 'excessive exercisers' varied and appeared inconsistent. There were no differences in any disorders for objective binge eaters.

DISCUSSION

Patients who induce vomiting have more psychiatric comorbidity than 'non-vomiters', both lifetime and recent, and may benefit from diagnostic recognition as a separate group, for example 'vomiting' or 'purging' ED, who can then receive specialist treatment for their comorbidity and associated problems.
