Frequency of anxiety after stroke: a systematic review and meta-analysis of observational studies.

BACKGROUND AND PURPOSE: Negative psychological outcomes occur frequently after stroke; however, there is uncertainty regarding the occurrence of anxiety disorders and anxiety symptoms after stroke. A systematic review of observational studies was conducted that assessed the frequency of anxiety in stroke patients using a diagnostic or screening tool. SUMMARY OF REVIEW: Databases were searched up to March 2011. A random effects model was used to summarize the pooled estimate. Statistical heterogeneity was assessed using the I(2) statistic. Forty-four published studies comprising 5760 stroke patients were included. The overall pooled estimate of anxiety disorders assessed by clinical interview was 18% (95%confidence interval 8-29%, I(2)  = 97%) and was 25% (95% confidence interval 21-28%, I(2)  = 90%) for anxiety assessed by rating scale. The Hospital Anxiety and Depression Scale-Anxiety subscale 'probable' and 'possible' cutoff scores were the most widely used assessment criteria. The combined rate of anxiety by time after stroke was: 20% (95% confidence interval 13-27%, I(2)  = 96%) within one-month of stroke; 23% (95% confidence interval 19-27%, I(2)  = 84%) one to five-months after stroke; and 24% (95% confidence interval 19-29%, I(2)  = 89%) six-months or more after stroke. CONCLUSION: Anxiety after stroke occurs frequently although methodological limitations in the primary studies may limit generalizability. Given the association between prevalence rates and the Hospital Anxiety and Depression Scale-Anxiety cutoff used in studies, reported rates could in fact underrepresent the extent of the problem. Additionally, risk factors for anxiety, its impact on patient outcomes, and effects in tangent with depression remain unclear

Prospective study of shoulder strength, shoulder range of motion, and lymphedema in breast cancer patients from pre-surgery to 5 years after ALND or SLNB

OBJECTIVE: Determine the changes in shoulder strength, shoulder range of motion, and arm volume in breast cancer patients treated with sentinel lymph node biopsy (SLNB) or axillary lymph node dissection (ALND) METHOD: Sixty-eight SLNB and 44 ALND patients were followed up from pre-surgery to 5 years after surgery. Primary outcomes were the differences between affected and non-affected sides for the following: shoulder strength measured by dynamometry, shoulder range of motion measured by goniometry, and lymphedema measured by volume. As a secondary outcome, health-related quality of life (HRQL) was assessed by the Short Form-36 Health Survey (SF-36) and the Functional Assessment of Cancer Therapy for breast cancer (FACT-B+4) questionnaires. Changes over time were tested for SLNB and ALND using univariate repeated measures analysis of variance. Generalized estimating equation models were constructed to assess the effect of SLNB and ALND over time. RESULTS: After 5 years, the ALND group had significant loss of strength for internal rotators (1.39 kg, p = 0.001) and significant arm volume increase (132.45 mL, p = 0.031). The ALND group had a greater number of patients with clinically relevant internal rotator strength loss (38.7 vs. 13.6%, p = 0.012) and a greater number of lymphedema requiring treatment (33.3 vs. 3.4%, p < 0.001) than the SLNB group. A loss of strength for shoulder external rotators, shoulder range of motion, and HRQL in physical and arm domains persisted at 5 years in both SLNB and ALND groups. CONCLUSION: These results could help understand and plan the prevention, needs, and long-term care of breast cancer patients

Gothenburg very early supported discharge study (GOTVED) NCT01622205 : a block randomized trial with superiority design of very early supported discharge for patients with stroke

BACKGROUND: Stroke is the disease with the highest costs for hospital care and also after discharge. Early supported discharge (ESD) has shown to be efficient and safe and the best results with well-organised discharge teams and patients with less severe strokes. The aim is to investigate if very early supported discharge (VESD) for stroke patients in need for on-going individualised rehabilitation at home is useful for the patient and cost effective. METHODS/DESIGN: A randomized controlled trial comparing VESD with ordinary discharge. Inclusion criteria: confirmed stroke, &gt;18 years of age, living within 30 min from the stroke unit, on day 2 0-16 points on the National institute of health stroke scale (NIHSS) and 50-100 points on the Barthel Index (BI), with BI 100 then the patient can be included if the Montreal Cognitive Assessment is &lt; 26. Exclusion criteria are: NIHSS &gt;16, BI &lt; 50, life expectancy &lt; 1 year, inability to speak or to communicate in Swedish. The inclusion occurs on day 4 and in block randomization of 20 and with blinded assessor. Primary outcome: levels of anxiety and depression. Secondary outcomes: independence, security, level of function, quality of health, needs of support in activities of daily living and caregiver burden. Power calculation is based on the level of anxiety and with a power of 80%, p-value 0.05 (2 sided test) 44 persons per group are needed. Data is gathered on co-morbidity, re-entry to hospital, mortality and a health economic analysis. Interviews will be accomplished with a strategic sample of 15 patients in the intervention group before discharge, within two weeks after homecoming and 3 months later. Interviews are also planned with 15 relatives in the intervention group 3 months after discharge. DISCUSSION: The ESD studies in the Cochrane review present hospital stays of a length that no longer exist in Sweden. There is not yet, to our knowledge, any study of early supported discharge with present length of hospital stay. Thus it is not clear if home rehabilitation nowadays without risks, is cost effective, or with the same patient usefulness as earlier studies. TRIAL REGISTRATION: ClinicalTrials.gov NCT01622205
