Visual evoked potential — a tool in the diagnosis of hepatic encephalopathy?

Visual evoked potentials (VEP) have been suggested to be of value in the diagnosis of subclinical and mild hepatic encephalopathy. In the present study, a comparison between VEP and four psychometric tests (number connection test A and B, digit symbol and word memory test) was performed in 42 cirrhotic patients, 17 of whom had clinical signs of encephalopathy. The results were compared to sex- and age-matched healthy controls. The VEP latencies for P2 (the second positive wave) and N3 (the third negative wave) were 11% and 26% longer (P less than 0.01-0.001) in the patients than in the controls. Moreover, the latencies for N2 (the second negative wave) and P2 were longer in the encephalopathic as compared to the non-encephalopathic patients (P less than 0.05). There was a significant correlation between the latencies for N2 and number connection tests A and B and digit symbol test. However, of the patients with clinical encephalopathy, less than half had VEP latencies longer than the mean +/- 2 S.D. above those for the controls. In contrast, none of the encephalopathic patients had normal results on the psychometric tests. This study demonstrates that although statistically significant differences exist between groups of cirrhotic patients and controls, VEP is not a reliable tool for the diagnosis of encephalopathy in the individual patient.

Can children identify and achieve goals for intervention? A randomized trial comparing two goal-setting approaches.

The efficacy of two different goal‐setting approaches (childrens self‐identified goals and goals identified by parents) were compared on a goal‐directed, task‐oriented intervention.

A client-centred ADL intervention : three-month follow-up of a randomized controlled trial

Abstract Objective: The aim was to study a client-centred activities of daily living (ADL) intervention (CADL) compared with the usual ADL intervention (UADL) in people with stroke regarding: independence in ADL, perceived participation, life satisfaction, use of home-help service, and satisfaction with training and, in their significant others, regarding: caregiver burden, life satisfaction, and informal care. Methods: In this multicentre study, 16 rehabilitation units were randomly assigned to deliver CADL or UADL. The occupational therapists who provided the CADL were specifically trained. Eligible for inclusion were people with stroke treated in a stroke unit ≤3 months after stroke, dependent in ≥two ADL, not diagnosed with dementia, and able to understand instructions. Data were collected at inclusion and three months thereafter. To detect a significant difference between the groups in the Stroke Impact Scale (SIS) domain “participation”, 280 participants were required. Intention-to-treat analysis was applied. Results: At three months, there was no difference in the outcomes between the CADL group (n = 129) and the UADL group (n = 151), or their significant others (n = 87/n = 93) except in the SIS domain “emotion” in favour of CADL (p = 0.04). Conclusion: The CADL does not appear to bring about short-term differences in outcomes and longer follow-ups are required.

Changes in the impact of stroke between 3 and 12 months post-stroke, assessed with the Stroke Impact Scale

OBJECTIVEnTo examine data collected using the Stroke Impact Scale 3.0 (SIS) at 3 and 12 months post-stroke, and to explore any clinically meaningful changes in everyday life in relation to age, gender and stroke severity.nnnDESIGNnProspective longitudinal study.nnnMETHODSnA total of 204 persons were assessed using the SIS at 3 and 12 months after onset of stroke. Changes in domain scores were calculated over time and in relation to age, gender and stroke severity.nnnRESULTSnThe Strength, Hand Function and Participation domains had the highest perceived impact at 3 and 12 months, indicating problems in everyday life. Stroke recovery was perceived to be significantly higher at 12 than at 3 months irrespective of stroke severity, age or gender. The impact on the Strength and Emotion domains was significantly lower at 12 months than at 3 months. Most clinically meaningful changes, both positive and negative (±u200915 points), were seen in the Participation domain and in Stroke recovery. Few changes were associated with age, gender or stroke severity.nnnCONCLUSIONnBoth positive and negative clinically meaningful changes related to impact of stroke were found between 3 and 12 months post-stroke. Therefore it is important to pay close attention to patients perceptions of their everyday life situation during rehabilitation and at discharge.

The combined perceptions of people with stroke and their carers regarding rehabilitation needs 1 year after stroke: a mixed methods study.

Objectives The aim of the study was to explore the associations between the dyad’s (person with stroke and informal caregiver) perception of the person with stroke’s rehabilitation needs and stroke severity, personal factors (gender, age, sense of coherence), the use of rehabilitation services, amount of informal care and caregiver burden. Further, the aim was to explore the personal experience of everyday life changes among persons with stroke and their caregivers and their strategies for handling these 1u2005year after stroke. Design A mixed methods design was used combining quantitative and qualitative data and analyses. Setting Data were mainly collected in the participants’ homes. Outcome measures Data were collected through established instruments and open-ended interviews. The dyads perceptions of the person with stroke’s rehabilitation needs were assessed by the persons with stroke and their informal caregivers using a questionnaire based on Ware’s taxonomy. The results were combined and classified into three groups: met, discordant (ie, not in agreement) and unmet rehabilitation needs. To assess sense of coherence (SOC) in persons with stroke, the SOC-scale was used. Caregiver burden was assessed using the Caregiver Burden Scale. Data on the use of rehabilitation services were obtained from the computerised register at the Stockholm County Council. Participants 86 persons with stroke (mean age 73u2005years, 38% women) and their caregivers (mean age 65u2005years, 40% women). Results Fifty-two per cent of the dyads perceived that the person with stroke’s need for rehabilitation was met 12u2005months after stroke. Met rehabilitation needs were associated with less severe stroke, more coping strategies for solving problems in everyday activities and less caregiver burden. Conclusions Rehabilitation interventions need to focus on supporting the dyads’ process of psychological and social adaptation after stroke. Future studies need to explore and evaluate the effects of using a dyadic perspective throughout rehabilitation.

Thermogenic response to intravenous nutrition in patients with cirrhosis

Energy expenditure was determined using continuous indirect calorimetry in the basal state and during 3 h of total parenteral nutrition (TPN) in 8 patients with cirrhosis and 8 healthy volunteers. TPN consisted of glucose, fat and amino acids and had a glucose/fat ratio of 50:50. The infusion rate was set to provide energy corresponding to 62.5% of the individually measured 24-h resting energy expenditure. In the basal state energy expenditure was similar in patients and controls while the respiratory quotient (RQ) was lower in the patients (0.78 +/- 0.01 vs. 0.82 +/- 0.01, mean +/- SEM, p < 0.05). During TPN, energy expenditure increased progressively during the 3-h infusion period. The average rise in energy expenditure was similar in patients (19.1 +/- 1.2%) and in controls (21.4 +/- 1.6%, n.s.). The RQ rose in both groups, but more in the patients with cirrhosis. At the end of the study, RQ was higher in patients (0.89 +/- 0.01) than in controls (0.85 +/- 0.01, p < 0.05). It is concluded that the nutrient-induced rise in energy expenditure during TPN is not significantly different in patients with cirrhosis and control subjects. Furthermore, the results indicate that the increased fat utilization in overnight fasting cirrhotic patients is rapidly shifted to an augmented carbohydrate oxidation during TPN, possibly as a consequence of marked hyperinsulinemia.

Training in client-centeredness enhances occupational therapist documentation on goal setting and client participation in goal setting in the medical records of people with stroke

Objective: The aim of the present study was to compare client-centeredness as it was documented by the occupational therapists in the units randomized to the intervention clusters with documentation by occupational therapists in the control clusters. Design: Comparison of medical records. Setting: The study is conducted in a context of a randomized controlled trial in Sweden, with 16 post-stroke rehabilitation units cluster randomized to intervention or control group. Subjects: Occupational therapist documentation in medical records of 279 clients with stroke. Main measures: The medical records were reviewed for their level of client-centeredness using a protocol developed from the Stewart et al model. The occupational therapists in the intervention groups participated in a workshop training to enhance their client-centeredness. Results: Occupational therapists with training in client-centeredness documented significantly more on goal setting (OR = 4.1; 95% CI, 1.87-8.81), on client participation in goal setting (OR=11.34; 95% CI, 5.97-21.57), on how the goals could be reached (OR=2.8; 95% CI, 1.7-4.62), on client participation in how goals could be reached (OR=4.56; 95% CI, 2.73-7.64), on the follow-up on goals (OR=5.77; 95% CI, 2.78-11-98) and on client participation in follow-up on goals (OR=7.44, 95% CI, 4.33-12.8). This association remained after adjustment for healthcare setting, client socio-demographic variables, and stroke severity. Conclusion: Documentation of goal setting and client participation in goal setting can be influenced by training.

Splanchnic and peripheral glucose metabolism in cirrhosis

The effects of glucose and insulin administration on splanchnic and leg exchange of glucose were investigated in seven patients with cirrhosis and six sex- and age-matched healthy controls using the catheter technique. After a basal period, glucose infusion (1 mg.kg-1.min-1) was given for 45 min, followed by a 2-h euglycemic insulin clamp (1 mU.kg-1.min-1). In the basal state insulin levels were significantly higher in patients than in controls (25 +/- 4 vs. 7 +/- 2 microU/ml). Net splanchnic glucose output tended to be lower in patients than in controls (0.50 +/- 0.16 vs 0.73 +/- 0.11 mmol/min nonsignificant), as did leg glucose uptake (0.06 +/- 0.01 vs 0.08 +/- 0.02 mmol/min, non-significant). Glucose infusion resulted in a significant rise in leg glucose uptake, while net splanchnic glucose output decreased in both groups. During the euglycemic insulin clamp, insulin concentrations rose to 110 +/- 10 and 80 +/- 8 microU/ml in patients and controls, respectively. C-peptide concentrations decreased in the healthy controls but were unchanged from the basal level in patients with cirrhosis. Glucose disposal during the last half hour of the clamp was 1.12 +/- 0.08 and 3.19 +/- 0.04 mmol/min in patients and controls, respectively (p < 0.001). Glucose was taken up by the splanchnic region in both groups but this uptake was significantly greater in patients than in controls (0.42 +/- 0.05 vs. 0.25 +/- 0.06 mmol/min, p < 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

Time trends in axilla management among early breast cancer patients: Persisting major variation in clinical practice across European centers

Abstract Background We examined time trends in axilla management among patients with early breast cancer in European clinical settings. Material and methods EUROCANPlatform partners, including population-based and cancer center-specific registries, provided routinely available clinical cancer registry data for a comparative study of axillary management trends among patients with first non-metastatic breast cancer who were not selected for neoadjuvant therapy during the last decade. We used an additional short questionnaire to compare clinical care patterns in 2014. Results Patients treated in cancer centers were younger than population-based registry populations. Tumor size and lymph node status distributions varied little between settings or over time. In 2003, sentinel lymph node biopsy (SLNB) use varied between 26% and 81% for pT1 tumors, and between 2% and 68% for pT2 tumors. By 2010, SLNB use increased to 79–96% and 49–92% for pT1 and pT2 tumors, respectively. Axillary lymph node dissection (ALND) use for pT1 tumors decreased from between 75% and 27% in 2003 to 47% and 12% in 2010, and from between 90% and 55% to 79% and 19% for pT2 tumors, respectively. In 2014, important differences in axillary management existed for patients with micrometastases only, and for patients fulfilling the ACOSOG Z0011 criteria for omitting ALND. Conclusion This study demonstrates persisting differences in important aspects of axillary management throughout the recent decade. The results highlight the need for international comparative patterns of care studies in oncology, which may help to identify areas where further studies and consensus building may be necessary.

A cluster randomized controlled trial of a client-centred, activities of daily living intervention for people with stroke: one year follow-up of caregivers

Objective: Compare caregiver burden, provision of informal care, participation in everyday occupations and life satisfaction of caregivers to people with stroke, who either had received a client-centred, activities of daily living intervention or usual activities of daily living interventions. Design: A multicentre cluster randomized controlled trial in which 16 rehabilitation units were randomly assigned to deliver a client-centred, activities of daily living intervention or usual activities of daily living interventions. Caregiver outcomes were compared cross-sectionally at 12u2009months and changes in outcomes between three and 12 months after people with stroke were included in the study. Setting: Inpatient and outpatient rehabilitation. Participants: Caregivers of people with stroke enrolled in the trial. Intervention: A client-centred, activities of daily living intervention aiming to increase agency in daily activities and participation in everyday life for people after stroke. Main measures: Caregiver Burden Scale, Occupational Gaps Questionnaire, LiSat-11. Results: There were no differences in outcomes between caregivers in the client-centred, activities of daily living (nu2009=u200988) and the usual activities of daily living (nu2009=u200995) group at 12u2009months. The caregiver burden score was 42.7 vs. 41.8, pu2009=u20090.75, mean occupational gaps were 3.5 vs. 4.0, pu2009=u20090.52 and satisfaction with life was 53% vs. 50%, pu2009=u20090.87. There were no differences in changes between three and 12u2009months. However, within groups there were significant differences in caregiver burden, factor general strain, for caregivers in the client-centred, activities of daily living group, and in provision of informal care for the usual activities of daily living group. Conclusion: The client-centred intervention did not bring about any difference between caregiver-groups, but within groups some difference was found for caregiver burden and informal care.
