'It's tough. It is hard': A qualitative interview study of staff and volunteers caring for hospice in-patients with delirium.

BACKGROUND: Delirium is a distressing condition often experienced by hospice in-patients. Increased understanding of current multidisciplinary care of delirium is needed to develop interventions in this setting. AIM(S): To explore hospice staff and volunteers' practice, its influences and what may need to change to improve hospice delirium care. DESIGN: Qualitative interview study using behaviour change theory from a critical realist stance. SETTING/PARTICIPANTS: Thirty-seven staff, including different professional groups and roles, and volunteers were purposively sampled from two in-patient hospices. RESULTS: We found that participants' practice focus was on managing hyperactive symptoms of delirium, through medication use and non-pharmacological strategies. Delirium prevention, early recognition and hypoactive delirium received less attention. Our theoretically-informed analysis identified this focus was influenced by staff and volunteers' emotional responses to the distress associated with hyperactive symptoms of delirium as well as understanding of delirium prevention, recognition and care, which varied between staff groups. Non-pharmacological delirium management was supported by adequate staffing levels, supportive team working and a culture of person-centred and family-centred care, although behaviours that disrupted the calm hospice environment challenged this. CONCLUSIONS: Our findings can inform hospice-tailored behaviour change interventions that develop a shared team understanding and engage staff's emotional responses to improve delirium care. Reflective learning opportunities are needed that increase understanding of the potential to reduce patient distress through prevention and early recognition of delirium, as well as person-centred management. Organisational support for adequate, flexible staffing levels and supportive team working is required to support person-centred delirium care.

Similar neurocognitive patterns in patients treated with lenalidomide: chemobrain effect?

Purpose: o report and describe cognitive impairments during lenalidomide treatment in three patients. Despite the relevant clinical impact of chemotherapy-related cognitive deficit (known as "chemobrain effect"), very few data are available in the literature. Methods: We present three subjects who developed cognitive impairment during treatment with lenalidomide. Their neuropsychological assessment was evaluated in order to better define the cognitive areas involved. For each patient medical history, drug therapy, physical examination and other instrumental tests (brain CT scan and/or MRI scan, FDG-PET and electroencephalography) were collected. Results: In all patients, we observed an homogeneous neuropsychological pattern characterized by long-term verbal and visuospatial memory deficits, and decline in attentional and executive functions. Conclusions: Lenalidomide treatments can determine severe cognitive impairments especially in elderly patients. Our data suggest the need for a careful evaluation of cognitive decline risk before and after drug administration. However, larger studies are required to confirm our findings.

Vitamin D Status in Paget Disease of Bone and Efficacy-Safety Profile of Cholecalciferol Treatment in Pagetic Patients with Hypovitaminosis D.

Adequate vitamin D status is essential for skeletal health. Paget's disease of bone (PDB) is a common metabolic skeletal disorder, but data regarding the vitamin D status in PDB patients are lacking. We performed a case-control study to estimate vitamin D status in 708 PDB patients and in 1803 healthy controls from Italy and an observational prospective study to evaluate the efficacy-safety profile of oral cholecalciferol treatment [400.000 International Units (UI) of cholecalciferol administered in cycles of 8 weeks until 25OHD levels reaches 70 nmol/L as primary therapy and 50.000 UI of cholecalciferol administered every 2 weeks for 52 weeks for the maintenance therapy] in 82 PDB patients with hypovitaminosis D, i.e., 25OHD < 50 nmol/L. The main outcome measures for the prospective study were 25OHD levels, metabolic risk factors (RF) for nephrolithiasis, bone pain score (BPS), and pain medication score (PMS). Over half of PDB patients had hypovitaminosis D. Among PDB patients treated with cholecalciferol, 76 patients reached 25OHD levels ≥ 70 nmol/L after the first cycle of primary therapy and the remaining six patients after a second cycle. The maintenance therapy guaranteed 25OHD levels ≥ 70 nmol/L during the entire follow-up. The increase in 25OHD levels reduced PTH, BPS, and PMS levels, without changes in RF for nephrolithiasis. We can conclude that (i) hypovitaminosis D is frequent in PDB patients, (ii) cholecalciferol significantly increased 25OHD levels in PDB patients, and (iii) the correction of hypovitaminosis D improves the quality of life of PDB patients without inducing significant changes in RF for nephrolithiasis.

Length of Stay in the Emergency Department and Occurrence of Delirium in Older Medical Patients.

OBJECTIVES: To determine whether emergency department (ED) length of stay before ward admission is associated with incident delirium in older adults. DESIGN: Prospective cohort study. SETTING: Hospital. PARTICIPANTS: Individuals aged 75 and older without delirium at ED entry, coma, aphasia, stroke, language barrier, psychiatric disorder, or alcohol abuse (N = 330). MEASUREMENTS: On ED admission, individuals underwent standardized evaluation of comorbidity (Cumulative Illness Rating Scale), cognitive impairment (Short Portable Mental Status Questionnaire), functional independence (activities of daily living, instrumental activities of daily living), pain (Numeric Rating Scale), and acute clinical conditions (Acute Physiology and Chronic Health Evaluation II). During the first 3 days after ward admission, the presence of delirium (defined as ≥1 delirium episodes within 72 hours) was assessed daily using a rapid assessment for delirium (4AT scale). ED length of stay was calculated as the time (hours) between ED registration and when the person left the ED. RESULTS: ED length of stay longer than 10 hours (odds ratio (OR) = 2.23, 95% confidence interval (CI) = 1.13-4.41), moderate to severe cognitive impairment (OR = 5.47, 95% CI = 2.76-10.85), and older age (OR = 1.07, 95% CI = 1.01-1.13) were associated with delirium onset. CONCLUSION: ED length of stay longer than 10 hours was associated with greater risk of delirium in hospitalized older adults, after adjusting for age and cognitive impairment.

Association of autoimmunity to autonomic nervous structures with nerve function in patients with type 1 diabetes: a 16-year prospective study.

OBJECTIVE We prospectively evaluated the association between autoimmunity to autonomic nervous structures and autonomic neuropathy in type 1 diabetes in relation to clinical variables. RESEARCH DESIGN AND METHODS A cohort of 112 patients with type 1 diabetes was prospectively followed from adolescence (T0) to approximately 4 (T4) and 16 (T16) years later. Standard cardiovascular (CV) tests and neurological examination were performed and related to the presence of circulating antibodies (Ab) to autonomic nervous structures detected at T0 and T4. Quality of life was assessed by a diabetes-specific questionnaire. RESULTS Sixty-six patients (59% of the cohort) were reexamined at T16 (age 31.4 ± 2 years; disease duration 23.4 ± 3.7 years). Nineteen had circulating Ab to autonomic structures. Prevalence of abnormal tests and autonomic symptoms were higher in Ab-positive (68 and 26%, respectively) than Ab-negative (32 and 4%) patients (P < 0.05). Among Ab-positive patients, the relative risk (RR) of having at least one altered CV test was 5.77 (95% CI 1.56-21.33), and an altered deep breathing (DB) test (<15 bpm) was 14.65 (2.48-86.46). Previous glycemic control was the only other predictor (RR 1.06 [1.002-1.13]/mmol/mol HbA1c increase). Presence of Ab carried over a 68% probability of developing an altered CV test; absence of Ab carried a 91% probability of not having an altered DB test and an 89% probability of not having an altered Valsalva ratio. Autonomic neuropathy was independently associated with worse quality of life. CONCLUSIONS Circulating Ab to autonomic structures are associated with the development of autonomic dysfunction in young diabetic patients independent of glycemic control.

Clinical characteristics influence screening intervals for diabetic retinopathy.

AIMS/HYPOTHESIS: Most guidelines recommend annual screening for diabetic retinopathy (DR) but limited resources and the slow progression of DR suggest that longer recall intervals should be considered if patients have no detectable lesions. This study aimed to identify the cumulative incidence and time of development of referable DR in patients with no DR at baseline, classified by clinical characteristics. METHODS: Analysis was performed of data collected prospectively over 20 years in a screening clinic based in a teaching hospital according to a consensus protocol. The cumulative incidence, time of development and relative risk of developing referable retinopathy over 6 years following a negative screening for DR were calculated in 4,320 patients, stratified according to age at onset of diabetes (<30 or ≥ 30 years), being on insulin treatment at the time of screening and known duration of diabetes (<10 or ≥ 10 years). RESULTS: The 6 year cumulative incidence of referable retinopathy was 10.5% (95% CI 9.4, 11.8). Retinopathy progressed within 3 years to referable severity in 6.9% (95% CI 4.3, 11.0) of patients with age at onset ≥ 30 years, who were on insulin treatment and had a known disease duration of 10 years or longer. The other patients, especially those with age at onset <30 years, on insulin and <10 years duration, progressed more slowly. CONCLUSIONS/INTERPRETATION: Screening can be repeated safely at 2 year intervals in any patient without retinopathy. Longer intervals may be practicable, provided all efforts are made to ensure adherence to standards in procedures and to trace and recall non-attenders.
