The safety of breast-conserving therapy in patients with breast cancer aged < or = 40 years

BACKGROUND: The objectives of this study were to study the probability of local control after breast-conserving therapy (BCT) in a large population of patients with early-stage breast cancer aged < or = 40 years and to determine which factors had prognostic value. METHODS: All patients (n = 758) aged < or = 40 years with clinical stage I or II breast cancer who underwent BCT in general hospitals in the southern part of the Netherlands between 1988 and 2002 were selected for the current analysis. BCT included local excision of the tumor followed by irradiation of the breast. Of 758 patients, 329 patients (43%) received adjuvant systemic treatment, and 36 patients (5%) underwent a microscopically incomplete excision. The median follow-up was 8.5 years. RESULTS: During follow-up, 95 patients developed a local recurrence without evidence of distant disease at the time the recurrence was diagnosed. Contralateral breast cancer was diagnosed in 59 patients. The 5- and 10-year actuarial local recurrence rates were 9.0% (95% confidence interval [95% CI], 6.6-11.4%) and 17.9% (95% CI, 14.1-21.7%), respectively. In a multivariate analysis, adjuvant systemic treatment reduced the risk of local recurrence (hazards ratio [HR], 0.47; 95% CI, 0.28-0.78) and contralateral breast cancer (HR, 0.46; 95% CI, 0.24-0.87) by >50%. CONCLUSIONS: The risk of local recurrence in young patients who underwent BCT was reduced strongly by using adjuvant systemic treatment. This finding may provide an argument if favor of advising the use of systemic treatment for all patients aged < or = 40 years who undergo BCT.     

Short- and long-term influence of diet and simvastatin on brachial artery endothelial function

BACKGROUND: Endothelium-dependent dilation (EDD) has often been studied in patients with hypercholesterolemia without overt coronary atherosclerosis where an improvement after statin treatment has been documented within few weeks. The aim of the study was to assess the short-term effect of diet as well as short- and long-term effect of simvastatin on EDD in patients with hypercholesterolemia and ischemic heart disease. METHODS: In 43 male patients with hypercholesterolemia and ischemic heart disease, EDD of the brachial artery was measured at baseline, after 3 months on a lipid-lowering diet, and after another 1, 3 and 12 months on simvastatin at 40 mg/day. RESULTS: Three months changes in EDD were neither influenced by diet nor short-term simvastatin therapy (4.9% vs. 4.9% vs. 4.8%, p=ns). Twelve months simvastatin treatment, however, significantly improved EDD by 32.7% (4.9% vs. 6.5%, p=0.007). By regression analysis an individual adjusted increase in EDD during the simvastatin treatment period was seen (coefficient 0.132 a month, p=0.002). A significant reduction in total cholesterol of 31.0% (6.1+/-0.8 vs. 4.2+/-0.7, p<0.001) and LDL cholesterol of 42.6% (4.0+/-0.8 vs. 2.2+/-0.6, p<0.001) was observed. CONCLUSION: EDD is improved after long-term simvastatin therapy; however, neither did 3 months diet or 3 months simvastatin therapy has influence on the EDD.     

Protein-Enriched Bread and Readymade Meals Increase Community-Dwelling Older Adults' Protein Intake in a Double-Blind Randomized Controlled Trial

Objectives

Sufficient protein intake can decrease undernutrition risk among community-dwelling older adults. This study aimed to increase community-dwelling older adults' daily protein intake with acceptable and applicable protein-enriched bread and readymade meals at home.

Vitamin D Supplementation Has No Impact on Cardiorespiratory Fitness,but Improves Inflammatory Status in Vitamin D Deficient Young Men Engaged in Resistance Training

Data on the effect of vitamin D (Vit-D) supplementation on cardiorespiratory fitness (VO₂max) are conflicting. A possible source of discrepancies in the literature is the heterogeneity in baseline Vit-D status among participants in previous studies. The main objectives of the present study were to assess the impact of Vit-D supplementation on VO₂max and inflammatory status in Vit-D deficient young healthy men. Participants (n = 39, baseline serum Vit-D level < 50 nmol/L) were quasi-randomly assigned to one of the two groups, which, in a double-blind manner, supplemented their diet daily with either Vit-D (8000 IU; VD) or placebo (PLC) and concomitantly performed a 12-week supervised resistance training program. During the 12-week intervention, serum Vit-D concentrations increased 3.9-fold (p < 0.001) in the VD group while no changes occurred in the PLC group. Baseline VO₂max did not differ in the two groups and remained unchanged during the intervention. Serum interleukin-10/tumour necrosis factor alpha ratio increased significantly (30%, p = 0.007; effect size 0.399) in VD but not in PLC group. In conclusion, 12-week Vit-D supplementation increases serum 25(OH)D levels and improves inflammatory status, but has no impact on VO₂max in Vit-D deficient young men engaged in resistance training.     

Understanding rebel nurse leadership-as-practice: Challenging and changing the status quo in hospitals

Some nurses are responding rebelliously to the changing healthcare landscape by challenging the status quo and deviating from suboptimal practices, professional norms, and organizational rules. While some view rebel nurse leadership as challenging traditional structures to improve patient care, others see it as disruptive and harmful. These diverging opinions create dilemmas for nurses and nurse managers in daily practice. To understand the context, dilemmas, and interactions in rebel nurse leadership, we conducted a multiple case study in two Dutch hospitals. We delved into the mundane practices to expand the concept of leadership-as-practice. By shadowing rebel nurse practices, we identified three typical leadership practices which present the most common “lived” experiences and dilemmas of nurses and nurse managers. Overall, we noticed that deviating acts were more often quick fixes rather than sustainable changes. Our research points to what is needed to change the status quo in a sustainable manner. To change unworkable practices, nurses need to share their experienced dilemmas with their managers. In addition, nurse managers must build relationships with other nurses, value different perspectives, and support experimenting to promote collective learning.     

Prospective cohort study of high-volume transanal irrigation in patients with constipation and/or faecal incontinence

Aim

The aim of this work was to determine the clinical efficacy of high-volume transanal irrigation (TAI) in patients with constipation and/or faecal incontinence using validated symptom and quality of life questionnaires.

Method

This was a prospective cohort study of 114 consecutive patients with constipation and/or faecal incontinence (Rome IV defined) who started TAI. A comprehensive questionnaire was completed at baseline and 4, 12, 26 and 52 weeks’ follow-up. The primary objective was significant symptom reduction [≥30%; Cleveland Clinic Constipation Score (CCCS) and St Marks Incontinence Score (SMIS)] in those who continued TAI at 52 weeks. Secondary objectives were (1) continuation rates of TAI, (2) effect on quality of life (QoL) and (3) identification of predictors for continuation.

Results

A total of 59 (51.8%) patients with constipation, 26 (22.8%) with faecal incontinence and 29 (25.4%) with coexistent symptoms were included. At 52 weeks, 41 (36.0%) patients continued TAI, 63 (55.2%) stopped and 10 (8.8%) patients were lost to follow-up. In those who continued TAI at 52 weeks (n = 41), no reduction of constipation symptoms was observed. Median Patient Assessment of Constipation Quality of Life scores decreased on most domains, indicating QoL improvement. Reduction of faecal incontinence occurred in 5/9 (55.6%) patients with faecal incontinence and in 3/10 (30.0%) patients with coexistent symptoms. The median SMIS per-individual decreased in patients with coexistent symptoms (2; interquartile range 0–4; p = 0.023). Median Fecal Incontinence Quality of Life scores increased in most domains, indicating improved QoL. No clinical characteristics predicted continuation.

Conclusion

One-third (n = 41) of patients continued TAI at 52 weeks. In those who continued TAI at 52 weeks, symptoms of faecal incontinence (SMIS) were reduced but not constipation (CCCS). QoL related to both constipation and faecal incontinence improved. No clinical characteristics predicted continuation.
