Adherence to dietary guidelines and associated factors among rural Australian cancer survivors: a cross-sectional study.

PURPOSE: This study aimed to explore levels of adherence to dietary guidelines, and factors associated with dietary guideline adherence, among rural Australian cancer survivors. METHODS: A cross-sectional study was undertaken. We recruited a convenience sample of adults with cancer who attended the chemotherapy day unit or allied health appointments at a rural hospital in Baw Baw Shire, Victoria, Australia, between August 2017 and December 2021. Dietary guideline adherence was assessed by cross-referencing participants' responses to an adapted version of the Dietary Questionnaire for Epidemiological Studies with dietary recommendations in Australian dietary guidelines. Binary logistic regression was used to assess factors associated with dietary guideline adherence for fruits and whole red meats. RESULTS: There were 107 rural cancer survivors (median age, 67 years). Dietary guideline adherence was highest for alcohol (88%) followed by whole red meats (63%), fruits (56%), processed red meats (24%), cereals/breads/grains (7%), and vegetables (4%). Relative to those aged < 65 years, 65-74-year-olds had 5.7-fold greater odds (adjusted odds ratio (aOR) = 5.74, 95% confidence interval (CI) = 1.91-17.17) of adhering to the dietary guideline for fruits. Relative to those who had completed/ceased treatment, participants who were currently receiving treatment had 78% lower odds (aOR = 0.22, 95% CI = 0.09-0.59) of adhering to the dietary guideline for fruits. CONCLUSION: This study contributes preliminary data on adherence to dietary guidelines and associated factors among rural Australian cancer survivors. Dietary guideline adherence varied across food groups and was mostly low, albeit not markedly worse than Australia's national population for the fruits and vegetables groups. The mostly low adherence in our sample suggests a potential need to increase provision of dietary information, supportive care screening, and, wherever necessary, dietetics referrals, assessments, and interventions among rural cancer survivors. Larger, longitudinal studies of adherence to dietary guidelines and/or tailored, cancer-specific dietary recommendations should be undertaken in future.

The Danish Atrial Fibrillation Registry: A Multidisciplinary National Pragmatic Initiative for Monitoring and Supporting Quality of Care Based on Data Retrieved from Administrative Registries.

Aim: The Danish Atrial Fibrillation (AF) Registry monitors and supports improvement of quality of care for all AF patients in Denmark. This report describes the registry's administrative and organizational structure, data sources, data flow, data analyses, annual reporting, and feedback between the registry, clinicians, and the administrative system. We also report the selection process of the quality indicators and the temporal trends in results from 2017-2021. Methods and Results: The Danish AF Registry aims for complete registration and monitoring of care for all patients diagnosed with AF in Denmark. Administrative registries provide data on contacts to general practice, contacts to private cardiology practice, hospital contacts, medication prescriptions, updated vital status information, and biochemical test results. The Danish Stroke Registry provides information on stroke events. From 2017 to 2021, the proportion with a reported echocardiography among incident AF patients increased from 39.9% (95% CI: 39.3-40.6) to 82.6% (95% CI: 82.1-83.1). The initiation of oral anticoagulant therapy among patients with incident AF and a CHA2DS2-VASc score of ≥1 in men and ≥2 in women increased from 85.3% (95% CI: 84.6-85.9) to 90.4% (95% CI: 89.9-91.0). The 1-year and 2-year persistence increased from 85.2% (95% CI: 84.5-85.9) to 88.7% (95% CI: 88.0-89.3), and from 85.4% (95% CI: 84.7-86.2) to 88.2% (95% CI: 87.5-88.8), respectively. The 1-year risk of ischemic stroke among prevalent patients with AF decreased from 0.88% (95% CI: 0.83-0.93) to 0.71% (95% CI: 0.66-0.75). Variation in clinical performance between the five administrative Danish regions was reduced. Conclusion: Continuous nationwide monitoring of quality indicators for AF originating from administrative registries is feasible and supportive of improvements of quality of care.

Physical activity, obesity, and quality of life among rural Australian cancer survivors: a cross-sectional study.

PURPOSE: We aimed to describe physical activity (PA), obesity, and quality of life (QoL) among rural Australian cancer survivors, assess whether total and item-specific QoL are associated with sufficient PA and obesity, and assess whether PA and obesity interact with respect to QoL. METHODS: In a cross-sectional study, convenience sampling was used to recruit adult cancer survivors via a chemotherapy day unit and allied health professionals at a rural hospital in Baw Baw Shire, Australia. Exclusion criteria were acute malnutrition and end-of-life care. PA and QoL were measured using Godin-Shephard and 7-item Functional Assessment of Cancer Therapy (FACT-G7) questionnaires, respectively. Factors associated with total and item-specific QoL were assessed via linear and logistic regression, respectively. RESULTS: Among 103 rural cancer survivors, the median age was 66 years, 35% were sufficiently physically active, and 41% presented with obesity. Mean/median total QoL scores were 17 on the FACT-G7 scale (0-28; higher scores indicate better QoL). Sufficient PA was associated with better QoL ([Formula: see text]=2.29; 95% confidence interval [CI] = 0.26, 4.33) and more energy (odds ratio [OR] = 4.00, 95% CI = 1.48, 10.78) while obesity was associated with worse QoL ([Formula: see text]=-2.09; 95% CI = -4.17, -0.01) and more pain (OR = 3.88, 95% CI = 1.29, 11.68). The PA-obesity interaction was non-significant (p-value = 0.83). CONCLUSIONS: This is the first known study conducted among rural survivors of any cancer to find sufficient PA and obesity are associated with better and worse QoL, respectively. PA, weight management, and QoL-including energy and pain-should be considered when targeting and tailoring supportive care interventions for rural cancer survivors.

Lameness in piglets - should pain killers be included at treatment?

BACKGROUND: Joint swelling and lameness are the most obvious and persistent clinical signs of infectious arthritis in piglets. For a positive treatment effect of piglets with arthritis, early initiated treatments with antibiotics are desired. Hitherto pain-reducing drugs have rarely been used within veterinary medicine, but the potential of non steroid anti-inflammatory drugs (NSAID) are interesting from an animal welfare perspective. Therefore, the aim of this study was to compare the long term efficiency of treating lameness with and without pain relief. Further, the incidences of affected joints in lame piglets were analysed. RESULTS: In total 415 of the 6,787 liveborn piglets included in the study were diagnosed with lameness (6.1 %). Around 86 % of these diagnoses took place during the first 3 weeks of life. There was no difference in the incidence of lameness between the sexes, but lameness was most commonly diagnosed in the offspring to old sows (>4 parturitions). Lameness was diagnosed in about every second litter and on average about two pigs were diagnosed in the affected litters. The incidence of affected litters as well as affected piglets increased with ageing of the sows. Treatments with antibiotics solely and in combination with NSAID improved (P < 0.01 to 0.001) the clinical status from day to day, but the clinical response did not differ between the two treatment groups. Piglets that remained healthy were 1.1 and 1.7 kg heavier (P < 0.001) than piglets diagnosed with lameness at 5 and 9 weeks of age, respectively. There were no differences in piglet body weights between the treatment strategies at any time. CONCLUSIONS: The clinical response to penicillin was good. It was neither improved nor reduced by a concurrent administration of NSAIDs. Nevertheless NSAIDs may improve the animal welfare due to pain relief. An important finding of this study was that decreasing pain due to lameness not was negative in a long term perspective, i.e. reducing pain did not lead to overstrain of affected joints and no clinical signs of adverse effects were noted. Therefore the use of NSAIDs ought to be considered to improve the animal welfare, at least in severe cases.

Long-term L-Triiodothyronine (T3) treatment in stable systolic heart failure patients: a randomised, double-blind, cross-over, placebo-controlled intervention study.

BACKGROUND: Chronic heart failure (HF) is characterized by reduced serum T3 levels and increased activity of the T3 degrading enzyme deiodinase D3. This may result in an intracellular composition of the cardiomyocyte mimicking that of hypothyroidism. Short-term T3-administration to systolic HF patients might be beneficial. QUESTION: Does long-term treatment with T3 have a beneficial effect on cardiac function and neurohormonal activation in chronic systolic HF patients with serum T3 levels below 1·6 nmol/l? DESIGN: A randomized, double-blind, cross-over, placebo-controlled intervention study with oral T3 treatment twice daily for 3 months. The T3 dose was uptitrated to a final dose avoiding reduced TSH levels. PRIMARY END-POINT: Left-ventricular ejection fraction (LVEF). METHODS: Cardiac imaging was performed using multiple gated tomographic radionuclide ventriculography (MUGA-SPECT). Neurohormonal stimulation was evaluated by plasma measurements of natriuretic peptides, aldosterone, renin, noradrenalin and copeptin levels. The patients were monitored for potential cardiac arrhythmias at the start of each treatment period. RESULTS: Thirteen patients completed the protocol. Mean LVEF was 43%, range: 37-52 and serum T3 levels 1·4 nmol/l (0·9-1·6). The T3 dose was 20 µg per day (10-40). TSH levels did not change between groups, whereas serum T3 levels increased in the active arm. Cardiac function as measured by LVEF, end-diastolic and end-systolic volumes and cardiac output did not change during T3-treatment and neither did the neurohormonal profile. There were no side-effects in terms of cardiac arrhythmias and no change in resting heart rate. CONCLUSIONS: This study does not support the hypothesis that oral T3 treatment might be beneficial to patients with chronic, stable systolic HF with a modest degree of reduced LVEF and low-normal serum T3 concentrations. The study included both functional studies of heart contractility as well as measures of the neurohormonal activation.

Gated tomographic radionuclide angiography using cadmium-zinc-telluride detector gamma camera; comparison to traditional gamma cameras.

PURPOSE: Estimation of left ventricular ejection fraction (LVEF) with equilibrium 99MTc-HSA equilibrium radionuclide angiography (MUGA) is frequently used for assessing cardiac function. The purpose of this study was to compare intra- and interobserver variation between three different gamma cameras. MATERIALS AND METHODS: Eighty-two patients, scanned in the same sequential order on the three cameras. Each acquisition was analyzed twice by two technologists. Inter- and intraobserver variations were calculated as the coefficient of variation and the 95% confidence interval for limits of agreement between each sequence of analyses for each of the three cameras. RESULTS: The lowest intraobserver variations in LVEF for the two NaI-detector cameras were 3.1% (-4.0% to 3.5%) for the planar and 3.4% (-4.2% to 4.5%) for SPECT (P ≤ 0.001-0.019), the highest result for the CZT SPECT camera was 2.6% (-2.9% to 3.1%). Similarly, interobserver variation was 4.8% (-4.8% to 6.4%) and 4.9% (-5.4% to 7.5%), respectively, for each of the NaI-detector cameras and 3.3% (-3.4% to 4.3%) for the CZT SPECT camera (P ≤ 0.001-0.008). DISCUSSION: The CZT detector camera was superior to both NaI detector cameras regarding intra- and interobserver variation. The CZT SPECT camera may identify changes in LVEF with greater certainty than its NaI detector-equipped counterparts.

Peripheral markers of thyroid function: the effect of T4 monotherapy vs T4/T3 combination therapy in hypothyroid subjects in a randomized crossover study.

BACKGROUND: A recent randomized controlled trial suggests that hypothyroid subjects may find levothyroxine (l-T4) and levotriiodothyronine combination therapy to be superior to l-T4 monotherapy in terms of quality of life, suggesting that the brain registered increased T3 availability during the combination therapy. HYPOTHESIS: Peripheral tissue might also be stimulated during T4/T3 combination therapy compared with T4 monotherapy. METHODS: Serum levels of sex hormone-binding globulin (SHBG), pro-collagen-1-N-terminal peptide (PINP), and N-terminal pro-brain natriuretic peptide (NT-proBNP) (representing hepatocyte, osteoblast, and cardiomyocyte stimulation respectively) were measured in 26 hypothyroid subjects in a double-blind, randomized, crossover trial, which compared the replacement therapy with T4/T3 in combination (50 µg T4 was substituted with 20 µg T3) to T4 alone (once daily regimens). This was performed to obtain unaltered serum TSH levels during the trial and between the two treatment groups. Blood sampling was performed 24 h after the last intake of thyroid hormone medication. RESULTS: TSH remained unaltered between the groups ((median) 0.83 vs 1.18 mU/l in T4/T3 combination and T4 monotherapy respectively; P=0.534). SHBG increased from (median) 75 nmol/l at baseline to 83 nmol/l in the T4/T3 group (P=0.015) but remained unaltered in the T4 group (67 nmol/l); thus, it was higher in the T4/T3 vs T4 group (P=0.041). PINP levels were higher in the T4/T3 therapy (48 vs 40 µg/l (P<0.001)). NT-proBNP did not differ between the groups. CONCLUSIONS: T4/T3 combination therapy in hypothyroidism seems to have more metabolic effects than the T4 monotherapy.

New-onset atrial fibrillation is a predictor of subsequent hyperthyroidism: a nationwide cohort study.

AIMS: To examine the long-term risk of hyperthyroidism in patients admitted to hospital with new-onset AF. Hyperthyroidism is a well-known risk factor for atrial fibrillation (AF), but it is unknown whether new-onset AF predicts later-occurring hyperthyroidism. METHODS AND RESULTS: All patients admitted with new-onset AF in Denmark from 1997-2009, and their present and subsequent use of anti-thyroid medication was identified by individual-level linkage of nationwide registries. Patients with previous thyroid diagnosis or thyroid medication use were excluded. Development of hyperthyroidism was assessed as initiation of methimazole or propylthiouracil up to a 13-year period. Risk of hyperthyroidism was analysed by Poisson regression models adjusted for important confounders such as amiodarone treatment. Non-AF individuals from the general population served as reference. A total of 145,623 patients with new-onset AF were included (mean age 66.4 years [SD ±13.2] and 55.3% males) of whom 3% (4,620 events; 62.2% women) developed hyperthyroidism in the post-hospitalization period compared to 1% (48,609 events; 82% women) in the general population (n = 3,866,889). In both women and men we found a significantly increased risk of hyperthyroidism associated with new-onset AF compared to individuals in the general population. The highest risk was found in middle-aged men and was consistently increased throughout the 13-year period of observation. The results were confirmed in a substudy analysis of 527,352 patients who had thyroid screening done. CONCLUSION: New-onset AF seems to be a predictor of hyperthyroidism. Increased focus on subsequent risk of hyperthyroidism in patients with new-onset AF is warranted.

Shepherding major health system reforms: a conversation with German health minister Ulla Schmidt. Interview by Tsung-Mei Cheng and Uwe Reinhardt.

Americans looking for role models among foreign health systems may find Germany's, along with the Dutch system, of particular interest. These countries seek to harvest the power of competition among nongovernmental insurers and providers of health care within a unifying regulatory framework aimed at keeping the competition fair and preserving for health care, as much as is possible, Europe's hallowed Principle of Solidarity. In this interview, conducted on behalf of Health Affairs by Tsung-Mei Cheng and Uwe Reinhardt, Germany's long-serving minister of health, Ulla Schmidt, explains what ethical and economic imperatives have shaped Germany's health reforms in recent years.
