    Abstract Background: Thyroid cancer (TC) patients are understudied but appear to be at risk for poor physical and psychosocial outcomes. Knowledge of the course and determinants of these deteriorated outcomes is lacking. Furthermore, little is known about mediating biological mechanisms.
    Objectives: The WaTCh-study aims to; 1. Examine the course of physical and psychosocial outcomes. 2. Examine the association of demographic, environmental, clinical, physiological, and personality characteristics to those outcomes. In other words, who is at risk? 3. Reveal the association of mediating biological mechanisms (inflammation, kynurenine pathway) with poor physical and psychological outcomes. In other words, why is a person at risk?
    Design and methods: Newly diagnosed TC patients from 13 Dutch hospitals will be invited. Data collection will take place before treatment, and at 6, 12 and 24 months after diagnosis. Sociodemographic and clinical information is available from the Netherlands Cancer Registry. Patients fill-out validated questionnaires at each time-point to assess quality of life, TC-specific symptoms, physical activity, anxiety, depression, health care use, and employment. Patients are asked to donate blood three times to assess inflammation and kynurenine pathway. Optionally, at each occasion, patients can use a weighing scale with bioelectrical impedance analysis (BIA) system to assess body composition; can register food intake using an online food diary; and can wear an activity tracker to assess physical activity and sleep duration/quality. Representative Dutch normative data on the studied physical and psychosocial outcomes is already available.
    Impact: WaTCh will reveal the course of physical and psychosocial outcomes among TC patients over time and answers the question who is at risk for poor outcomes, and why. This knowledge can be used to provide personalized information, to improve screening, to develop and provide tailored treatment strategies and supportive care, to optimize outcomes, and ultimately increase the number of TC survivors that live in good health.

    Abstract Context: No consensus exists about the optimal duration of the low-iodine diet (LID) in the preparation of 131I therapy in differentiated thyroid cancer (DTC) patients.
    Objective: This work aimed to investigate if a LID of 4 days is enough to achieve adequate iodine depletion in preparation for 131I therapy. In addition, the nutritional status of the LID was evaluated.
    Methods: In this prospective study, 65 DTC patients treated at 2 university medical centers were included between 2018 and 2021. The patients collected 24-hour urine on days 4 and 7 of the LID and kept a food diary before and during the LID. The primary outcome was the difference between the 24-hour urinary iodine excretion (UIE) on both days.
    Results: The median 24-hour UIE on days 4 and 7 of the LID were not significantly different (36.1 mcg [interquartile range, 25.4-51.2 mcg] and 36.5 mcg [interquartile range, 23.9-47.7 mcg], respectively, P = .43). On day 4 of the LID, 72.1% of the DTC patients were adequately prepared (24-hour UIE < 50 mcg), and 82.0% of the DTC patients on day 7 (P = .18). Compared to the self-reported regular diet, DTC patients showed a significantly (P < .01) lower percentage of nutrient intake (calories, protein, calcium, iodine, and water) during the LID.
    Conclusion: The 24-hour UIE on day 4 of the LID did not differ from day 7, and therefore shortening the LID from 7 to 4 days seems justified to prepare DTC patients for 131I therapy in areas with sufficient iodine intake and may be beneficial to maintain a sufficient nutritional intake during DTC treatment.

    Abstract Aim: To explore the experiences of safety of adult patients during their haemodialysis treatment.
    Background: Haemodialysis is a complex treatment with a risk for harm that causes anxiety among many patients. To date, no in-depth study of haemodialysis patients' emotional responses to conditions of their treatment exists.
    Design: A descriptive exploratory qualitative study using content analysis was conducted.
    Methods: Outpatients (≥18 years old) (n = 12) who were treated with haemodialysis for more than half a year were purposefully selected from two haemodialysis units (one in an academic hospital and one in a top clinical hospital) in the Netherlands. Data were collected through in-depth individual interviews from January-April 2013. Analysis of the transcribed interviews consisted of open coding, creating categories and synthesis.
    Results: Patients defined 'safety' as feeling safe from physical or emotional threats. Four main categories were identified in the descriptions of haemodialysis patients' experiences of safety: (a) insecurity; (b) trust in the nurse; (c) presence of the nurse; and (d) patients' need to control their situation.
    Conclusion: Although haemodialysis patients perceived multiple risks, most patients reported feeling safe during their treatment. The nurse had a pivotal role in promoting patients' feelings of safety. Nurses should take into account patients' coping strategies because these coping strategies may cause some patients to feel anxious, especially when patients say that they leave everything to the nurse, yet they still desire control over their treatment.

    Abstract Background: When healthcare professionals or other involved parties prevent eligible patients from entering a trial as a research subject, they are gatekeeping. This phenomenon is a persistent problem in palliative care research and thought to be responsible for the failure of many studies.
    Aim: To identify potential gatekeepers and explore their reasons for gatekeeping in palliative care research.
    Design: A 'Review of Reasons' based on the systematic Preferred Reporting Items for Systematic Reviews and Meta-Analyses approach and a thematic synthesis.
    Data source: PubMed, Embase, Cumulative Index to Nursing and Allied Health Literature and PsycINFO from 2000 to May 20 2015 were searched. Studies in children (aged <18 years) and patients with dementia were excluded.
    Results: Thirty papers on gatekeeping in palliative care research were included. Five groups of potential gatekeepers were identified: healthcare professionals, research ethics committees, management, relatives and researchers. The fear of burdening vulnerable patients was the most reported reason for gatekeeping. Other reasons included 'difficulty with disclosure of health status', 'fear of burdening the patient's relatives', 'doubts about the importance or quality of the study', 'reticent attitude towards research and (research) expertise' and 'logistics'. In hospice and homecare settings, the pursuit of comfort care may trigger a protective attitude. Gatekeeping is also rooted in a (perceived) lack of skills to recruit patients with advanced illness.
    Conclusion: Gatekeeping is motivated by the general assumption of vulnerability of patients, coupled with an emphasis on the duty to protect patients. Research is easily perceived as a threat to patient well-being, and the benefits appear to be overlooked. The patients' perspective concerning study participation is needed to gain a full understanding and to address gatekeeping in palliative care research.

    Abstract Ever since the first descriptions of adrenal insufficiency following exogenous supplementation physicians dread to abolish perioperative glucocorticosteroid supplementation. Now, 55 years after the first publications we can challenge those first reports. However, these cases have resulted in the supplementation of supraphysiological doses of glucocorticosteroids to patients that use exogenous corticosteroids: the so-called perioperative glucocorticosteroid supplementation or "(gluco)corticosteroid stress scheme". It is very questionable whether a dose that exceeds the normal daily production of 5.7 mg cortisol per square meter of body surface area is necessary to prevent perioperative hypotension. Retrospective, prospective and randomised studies, though all methodologically flawed, are discussed and show that continuation of the "basal" amount of glucocorticosteroids is sufficient to counterbalance surgical stress. The current and rather defensive strategy of perioperative supraphysiological glucocorticosteroid supplementation is not embedded in medical evidence. Additionally, high doses of glucocorticosteroids have disadvantages that should not be ignored.

    Abstract Background: Healing of heel ulcers in patients with diabetes is considered to be poor, but there is relatively little information on the influence of ulcer location on ulcer healing.
    Methods: The influence of ulcer location on time to healing of diabetic foot ulcers was analysed by multivariate Cox regression analysis for 1000 patients included in the Eurodiale study, a prospective cohort study of patients with diabetic foot disease.
    Results: Median time to healing was 147 days for toe ulcers [(95% confidence interval (CI) 135-159 days)], 188 days for midfoot ulcers (95% CI 158-218 days) and 237 days for heel ulcers (95% CI 205-269 days) (p < 0.01). The median time to healing for plantar ulcers was 172 days (95% CI 157-187 days) and 155 days (95% CI 138-172 days) for nonplantar ulcers (p = 0.71). In multivariate Cox regression analysis, the hazard ratio for ulcer healing for midfoot and heel ulcers compared with toe ulcers was 0.77 (95% CI 0.64-0.92) and 0.62 (95% CI 0.47-0.83), respectively; the hazard ratio for ulcer healing for plantar versus nonplantar ulcers was 1 (95% CI 0.84-1.19). Other factors significantly influencing time to healing were the duration of diabetes, ulcer duration, the presence of heart failure and the presence of peripheral arterial disease.
    Conclusions: Time to ulcer healing increased progressively from toe to midfoot to heel, but did not differ between plantar and nonplantar ulcers. Our data also indicate that risk factors for longer time to healing differ from factors that affect the ultimate number of ulcers that heal (healing rate).

    Abstract Objective:   To improve the care of patients with painful diabetic polyneuropathy (PDP) by a specialized outpatient clinic for individuals referred by general practitioners and to determine the effects on pain, quality of life, and patient satisfaction.
    Material and methods:   One hundred twenty-one patients were prospectively enrolled. At baseline and after 12 months at end of treatment, patients filled in a set of validated questionnaires on severity and interference of pain, quality of life, anxiety and depression, and patient satisfaction with the service offered.
    Setting:   The outpatient clinic is part of a regional chronic care management program, which includes both hospital-based endocrinologists and general practitioners.
    Results:   Twenty-eight patients (27%) did not need any further treatment after one visit to the outpatient clinic. As initial drug, pregabalin was the most commonly prescribed drug (65%); amitriptyline was prescribed in only 30% due to its contraindications. Improvements were found in all pain scores (P < 0.05). Pain interference was improved in sleep (P < 0.01), general activity, and mood (P < 0.05). More than half of the patients (65%) were satisfied with the treatment and wished no further medication changes; 52% had a treatment success defined as pain relief ≥ 30%. Medication was stopped due to inefficacy in 9% of patients and changed due to adverse effects in 20% of the patients.
    Conclusions:   A specialized outpatient clinic for patients with PDP is an effective health care service. Using diagnostic instruments and a defined treatment algorithm, significant pain reduction was achieved in the majority of patients in a relative short period of time.

    Abstract Objective: To provide a comprehensive assessment of multiorgan insulin sensitivity in lean and obese subjects with normal glucose tolerance.
    Research design and methods: The hyperinsulinemic-euglycemic clamp procedure with stable isotopically labeled tracer infusions was performed in 40 obese (BMI 36.2 ± 0.6 kg/m(2), mean ± SEM) and 26 lean (22.5 ± 0.3 kg/m(2)) subjects with normal glucose tolerance. Insulin was infused at different rates to achieve low, medium, and high physiological plasma concentrations.
    Results: In obese subjects, palmitate and glucose R(a) in plasma decreased with increasing plasma insulin concentrations. The decrease in endogenous glucose R(a) was greater during low-, medium-, and high-dose insulin infusions (69 ± 2, 74 ± 2, and 90 ± 2%) than the suppression of palmitate R(a) (52 ± 4, 68 ± 1, and 79 ± 1%). Insulin-mediated increase in glucose disposal ranged from 24 ± 5% at low to 253 ± 19% at high physiological insulin concentrations. The suppression of palmitate R(a) and glucose R(a) were greater in lean than obese subjects during low-dose insulin infusion but were the same in both groups during high-dose insulin infusion, whereas stimulation of glucose R(d) was greater in lean than obese subjects across the entire physiological range of plasma insulin.
    Conclusions: Endogenous glucose production and adipose tissue lipolytic rate are both very sensitive to small increases in circulating insulin, whereas stimulation of muscle glucose uptake is minimal until high physiological plasma insulin concentrations are reached. Hyperinsulinemia within the normal physiological range can compensate for both liver and adipose tissue insulin resistance, but not skeletal muscle insulin resistance, in obese people who have normal glucose tolerance.
