RESUMO

Objective: The aim of this study was to analyze quantitative sleep changes and their implication on subjective cognitive decline (SCD). Objective sleep patterns were investigated by an actigraph and recorded at the baseline and 2-year after in order to examine specific sleep alterations in SCD. Background: Sleep disorders are very common among average elderly adults and an altered sleep pattern is known to be a risk factor for future development of mild cognitive impairment (MCI) and dementia. Recent studies have shown how sleep is objectively altered in average senior adults with SCD, without any other significant change in cognition and behavior or brain structure. Considering that both SCD and disrupted sleep are risk factors for future MCI and dementia, with sleep only as a modifiable risk factor, further research is required to deeply investigate the interaction between sleep and SCD. Methods: Among 70 community-dwelling elderly individuals who had been enrolled at baseline, 35 (64.6 ± 5.6 years, 15 M/20 F) underwent a complete neuropsychological battery and 1-week wrist actigraphy recording 2 years later during the follow-up stage. Individuals were divided into two groups according to their SCD Questionnaire (SCD-Q) score. Sleep hours, sleep efficiency and onset latency, napping and time awake after sleep onset (WASO) were collected. All individuals underwent structural magnetic resonance imaging (MRI) examination to exclude brain disorders. Data collection was performed at baseline and after 2 years at the follow-up phase. Results: A significantly different night sleep time between the two groups was observed: SCD showed a lower total sleep time (TST) than non-SCD subjects. Moreover, a total time spent in bed (TIB) was significantly lower in SCD subjects over 2 years of observation. Conclusions: Objective changes over time of the sleep pattern, specifically TIB and TST, are present in SCD individuals. The results of the study show that sleep alterations are common in SCD and underline the clinical importance of screening in order to assess sleep alterations as well as improve sleep in average adults with SCD complaints.

RESUMO

Outcome for elderly patients with acute myeloid leukemia (AML) is extremely poor. Intensive induction chemotherapy is often unsuitable. Sixty-six newly diagnosed AML patients (median age: 76years), ineligible for standard therapy, were consecutively treated with low-dose lenalidomide (10mg/day orally, days 1-21) plus 10mg/m2 low-dose cytarabine, subcutaneously, twice a day (days 1-15) every six weeks, up to 6 cycles. Complete remission (CR) rate was 36.3% according to intention-to-treat. Responding patients had a longer median overall survival than non-responders (517 vs. 70days, P<0.001). The achievement of CR was not predicted by bone marrow blast count, cytogenetics, molecular markers, prior MDS, white blood cell count. Conversely, by studying the global gene expression profile, we identified a molecular signature, including 309 genes associated with clinical response (CR versus no CR). Based on the expression of a minimal set of 16 genes, we developed an algorithm to predict treatment response, that was successfully validated by showing an overall accuracy of 88%. We met the primary endpoint of the study, by beating the estimated successful CR rate (P1) fixed at 30%. Moreover, CR induced by this 2-drug combo was efficiently predicted by genetic profiling, identifying a biomarker that warrants validation in independent series.

RESUMO

AIMS: To describe the nursing diagnoses, outcomes and interventions for patients admitted to intensive care units and to assess their possible relation with classical outcomes like length of stay and mortality. BACKGROUND: The analysis of nursing diagnosis frequencies may help to estimate the patients' complexity and the need for nursing interventions and can predict hospital outcomes. Nonetheless, few studies were conducted on critical patients. DESIGN: Prospective cohort observational study. METHODS: Between 15 July-31 October 2013 we collected the above-described nursing parameters of 100 subjects throughout their stay in intensive care. We classified the parameters according to established taxonomies. The independent association between the number of nursing diagnoses and length of stay/mortality was investigated with multiple regressions. RESULTS: We found an average of 19 diagnoses, 24 outcomes and 60 interventions per patient. Most frequently, the plans of care involved support for self-care deficits or interrupted family processes. They also included strategies to prevent infection, disuse syndrome and impairment of skin integrity. Nineteen nursing diagnoses were significantly related with mortality or length of stay in bivariate analyses. In regression models, the number of such diagnoses explained 29·7% of the variance in length of stay and was an independent predictor of mortality. CONCLUSION: In critically ill patients, the analysis of nursing diagnoses, outcomes and interventions confirmed an intense activity in response to a broad spectrum of patient needs. The number of nursing diagnoses allowed to predict patient outcomes.

RESUMO

Our aim was to study the influence of acute graft-versus-host disease (a-GVHD) on primary engraftment times after allogeneic transplantation. Primary engraftment and frequency of marrow granulocyte-macrophage colony-forming units and erythroid burst-forming units, at day +18, were studied in 126 allogeneic transplants. Patients were grouped according to the time when a-GVHD treatment with corticosteroids was started. The no-a-GVHD group are those who, during the first 3 months, had no need for a-GVHD treatment; the early-a-GVHD group are those who needed a-GVHD treatment within 19 days; and the postengraftment-a-GVHD group are those who were not on corticosteroid treatment at the time of engraftment but needed it after day +19. The no-a-GVHD group reached a neutrophil count (N) > 0.5 × 10(9)/L in a median of 17.8 days. The postengraftment-a-GVHD group reached N > 0.5 × 10(9)/L in a median of 21.4 days (p = 0.0003). The early-a-GVHD group had N > 0.5 × 10(9)/L in a median of +17.0 days (p = 0.23). When factors important for engraftment were studied in a multivariate analysis, postengraftment a-GVHD was a significant factor in delayed neutrophil and platelet engraftment. Both the early-a-GVHD and postengraftment-a-GVHD groups showed a significant reduction in frequency of granulocyte-macrophage colony-forming units and erythroid burst-forming units found in marrow at day +18. In conclusion, a-GVHD may influence early marrow reconstitution and is a relevant factor for primary myeloid and platelet engraftment.

RESUMO

INTRODUCTION: Noninvasive blood pressure (NIBP) monitoring methods are widely used in critically ill patients despite poor evidence of their accuracy. The erroneous interpretations of blood pressure (BP) may lead to clinical errors. OBJECTIVES: To test the accuracy and reliability of aneroid (ABP) and oscillometric (OBP) devices compared to the invasive BP (IBP) monitoring in an ICU population. MATERIALS AND METHODS: Fifty adult patients (200 comparisons) were included in a randomized crossover trial. BP was recorded simultaneously by IBP and either by ABP or by OBP, taking IBP as gold standard. RESULTS: Compared with ABP, IBP systolic values were significantly higher (mean difference ± standard deviation 9.74 ± 13.8; P < 0.0001). Both diastolic (-5.13 ± 7.1; P < 0.0001) and mean (-2.14 ± 7.1; P=0.0033) IBP were instead lower. Compared with OBP, systolic (10.80 ± 14.9; P < 0.0001) and mean (5.36 ± 7.1; P < 0.0001) IBP were higher, while diastolic IBP (-3.62 ± 6.0; P < 0.0001) was lower. Bland-Altman plots showed wide limits of agreement in both NIBP-IBP comparisons. CONCLUSIONS: BP measurements with different devices produced significantly different results. Since in critically ill patients the importance of BP readings is often crucial, noninvasive techniques cannot be regarded as reliable alternatives to direct measurements.

RESUMO

To date, no prospective study on Plerixafor 'on-demand' in combination with chemotherapy and granulocyte colony-stimulating factor (G-CSF) has been reported. We present an interim analysis of the first prospective study in which Plerixafor was administered on-demand in patients affected by multiple myeloma and lymphoma who received high dose cyclophosphamide or DHAP (dexamethasone, cytarabine, cisplatin) plus G-CSF to mobilize peripheral blood stem cells (PBSC). One hundred and two patients were evaluable for response. A cohort of 240 patients receiving the same mobilizing chemotherapy was retrospectively studied. Failure to mobilize CD34(+) cells in peripheral blood was reduced by 'on-demand' strategy compared to conventional mobilization; from 13·0 to 3·0% (P = 0·004). Failure to harvest CD34(+) cells 2 × 10(6) /kg decreased from 20·9 to 4·0% (P = 0·0001). The on-demand Plerixafor strategy also resulted in a lower rate of mobilization failure (P = 0·03) and harvest failure (P = 0·0008) when compared to a 'bias-adjusted set of controls'. Evaluation of economic costs of the two strategies showed that the overall cost of the two treatments were comparable when salvage mobilizations were taken into account. When in combination with cyclophosphamide or DHAP plus G-CSF, the 'on-demand' use of Plerixafor showed, in comparison to conventionally treated patients, a significant improvement in mobilization of PBSC with no increase in overall cost.
