Fatigue in the acute phase after first stroke predicts poorer physical health 18 months later.

ABSTRACT:

Objective

To determine whether fatigue in the acute phase following stroke predicts long-term patient-reported physical and mental health outcomes 18 months later.

Methods

Patients (n = 96, mean age 67.8 years, SD 12.9) were assessed within 2 weeks of hospital admission for first-ever stroke (acute phase) and 18 months later. Measures included the Fatigue Severity Scale and the Beck Depression Inventory II. The Short Form-36 was used to assess self-reported physical and mental health. Multivariate regression analysis was used to evaluate the relationship between acute phase fatigue and later health outcomes, controlling for relevant covariates.

Results

Acute phase fatigue was associated with physical health at 18-month follow-up, but not with mental health. After adjusting for other potential predictors of health outcomes, including age, sex, cohabitation status, acute phase physical or mental health, and depressive symptoms, acute phase fatigue remained a significant predictor of later physical health but not of later mental health. The reverse relationships were also examined, but neither physical nor mental health in the acute phase predicted fatigue at 18 months; the best predictor of fatigue at 18-month follow-up was acute phase fatigue.

Conclusions

These findings suggest that acute phase fatigue is an independent risk factor for poor physical health 18 months after stroke. Diagnosis and treatment of acute phase fatigue may improve physical health-related quality of life among stroke survivors. Effective treatments for poststroke fatigue, both in the acute phase and later in the recovery period, are needed.

Placental pathology predicts infantile physical development during first 18 months in Japanese population: Hamamatsu birth cohort for mothers and children (HBC Study).

Project description:The present study aimed to investigate the relationship between placental pathological findings and physiological development during the neonate and infantile periods. Study participants were 258 infants from singleton pregnancies enrolled in the Hamamatsu Birth Cohort for Mothers and Children (HBC Study) whose placentas were stored in our pathological division. They were followed up from birth to 18 months of age. Physiological development (body weight and the ponderal index [PI]) was assessed at 0, 1, 4, 6, 10, 14, and 18 months. Placental blocks were prepared by random sampling and eleven pathological findings were assessed, as follows: 'Accelerated villous maturation', 'Decidual vasculopathy', 'Thrombosis or Intramural fibrin deposition', 'Avascular villi', 'Delayed villous maturation', 'Maternal inflammatory response', 'Fetal inflammatory response', 'Villitis of unknown etiology (VUE)', 'Deciduitis', 'Maternal vascular malperfusion', and 'Fetal vascular malperfusion'. Mixed model analysis with the use of the xtmixed command by the generic statistical software, Stata version 13.1., identified 'Accelerated villous maturation' and 'Maternal vascular malperfusion' as significant predictors of a lower body weight and 'Deciduitis' as a significant predictor of a small PI, throughout the first 18 months of life. In conclusion, the present study is the first to demonstrate that some pathological findings of the placenta are associated with changes in infantile physical development during the initial 18 months of life in the Japanese population.

Weight change in the first 2 months of a lifestyle intervention predicts weight changes 8 years later.

Project description:ObjectiveExamine the relationship between 1- and 2-month weight loss (WL) and 8-year WL among participants enrolled in a lifestyle intervention.Methods2,290 Look AHEAD participants (BMI: 35.65 ± 5.93 kg/m(2) ) with type 2 diabetes received an intensive behavioral WL intervention.Results1- and 2-month WL were associated with yearly WL through Year 8 (P's < 0.0001). At Month 1, participants losing 2-4% and >4% had 1.62 (95% CI: 1.32, 1.98) and 2.79 (95% CI: 2.21, 3.52) times higher odds of achieving ≥5% WL at Year 4 and 1.28 (95% CI: 1.05,1.58) and 1.77 (95% CI: 1.40, 2.24) times higher odds of achieving ≥5% WL at Year 8, compared to those losing <2% initially. At Month 2, 3-6% WL resulted in greater odds of achieving ≥5% WL at Year 4 (OR = 1.85; CI: 1.48, 2.32), and >6% WL resulted in the greatest odds of achieving ≥5% WL at Year 4 (OR = 3.85; CI: 3.05, 4.88) and Year 8 (OR = 2.28; CI: 1.81, 2.89), compared to those losing <3%. Differences in adherence between WL categories were observed as early as Month 2.Conclusions1- and 2-month WL was associated with 8-year WL. Future studies should examine whether alternative treatment strategies can be employed to improve treatment outcomes among those with low initial WL.

Influence of Medication on Fatigue Six Months after Stroke.

Project description:Poststroke fatigue (PSF) is frequent and affects patients' quality of life. Medication use was hypothesized as being responsible for PSF. Our objective was to evaluate potential relationships between 6-month PSF and medication use at discharge and 6 months after an ischemic stroke. This study is part of STROKDEM, an ongoing longitudinal cohort study, whose main aim is to determine predictors of poststroke dementia. Patients were included within 72 hours after an ischemic stroke and followed up with standardized evaluations. Medication use 7 days and 6 months after stroke was rated, and polypharmacy was defined as the number of categories of treatments received by a patient. PSF was evaluated using the Chalder Fatigue Scale. Medical history, vascular risk factors, depression, anxiety, and sleep disturbances were evaluated. One hundred and fifty-three patients were included: 52.9% presented PSF. PSF at 6 months was not predicted by medication use at discharge nor associated with medication use at month 6. We found severity of PSF to be increased in patients with polypharmacy. Our results suggest that PSF is not a side effect of drugs use, which more reflects presence of disturbances frequently observed after stroke such as depression, anxiety, or sleep disturbances. Clinical study is registered on clinicaltrials.gov (NCT01330160).

Recovery of paretic lower extremity loading ability and physical function in the first six months after stroke.

Project description:ObjectivesTo evaluate poststroke recovery of paretic lower extremity loading, walking ability, and self-reported physical function; and to identify subject characteristics associated with recovery.DesignInception cohort study, with testing at monthly intervals from 1 to 6 months poststroke.SettingMedical center and research laboratory.ParticipantsVolunteer sample of individuals with first-ever, unilateral, noncerebellar stroke (N=33). A total of 78 individuals underwent screening, and 45 were found to be eligible. Of these, 8 declined participation, 2 were excluded because of deteriorating cognitive status, and 2 were lost to follow-up. The remaining 33 individuals enrolled in the study, and 30 (91%) completed the study.InterventionsNot applicable.Main outcome measuresOutcomes were loading of the paretic lower extremity when standing up from a chair, self-selected gait speed (GS), and Physical Functioning Index.ResultsData analyses using linear mixed models indicated that subjects improved over time for all outcomes. Baseline Fugl-Meyer (FM) lower extremity motor scale score was a predictor of immediate poststroke performance for paretic lower extremity loading and self-selected GS, and a predictor of recovery rate for paretic lower extremity loading. Factors identified as having significant effects on performance at 6 months poststroke were baseline FM lower extremity motor scale score for paretic lower extremity loading and self-selected GS and baseline star cancellation score (from the Behavioral Inattention Test) for paretic lower extremity loading.ConclusionsIndividuals with better baseline paretic lower extremity motor function have better ability to load that extremity during functional activities and faster walking speeds, and these advantages are still present at 6 months poststroke. Individuals with severe visuospatial neglect demonstrate less ability to load the paretic leg during functional activities at 6 months poststroke.

Acquisition of human polyomaviruses in the first 18 months of life.

Project description:We investigated the presence of 4 human polyomaviruses (PyVs) (WU, KI, Merkel cell, and Malawi) in respiratory specimens from a community-based birth cohort. These viruses typically were acquired when children were ≈1 year of age. We provide evidence that WU, KI, and Malawi, but not Merkel cell PyVs, might have a role in respiratory infections.

Physical activity, sleep, and fatigue in community dwelling Stroke Survivors.

Project description:Stroke can lead to physiological and psychological impairments and impact individuals' physical activity (PA), fatigue and sleep patterns. We analysed wrist-worn accelerometry data and the Fatigue Assessment Scale from 41 stroke survivors following a physical rehabilitation programme, to examine relationships between PA levels, fatigue and sleep. Validated acceleration thresholds were used to quantify time spent in each PA intensity/sleep category. Stroke survivors performed less moderate to vigorous PA (MVPA) in 10?minute bouts than the National Stroke guidelines recommend. Regression analysis revealed associations at baseline between light PA and fatigue (p?=?0.02) and MVPA and sleep efficiency (p?=?0.04). Light PA was positively associated with fatigue at 6 months (p?=?0.03), whilst sleep efficiency and fatigue were associated at 9 months (p?=?0.02). No other effects were shown at baseline, 6 or 9 months. The magnitude of these associations were small and are unlikely to be clinically meaningful. Larger trials need to examine the efficacy and utility of accelerometry to assess PA and sleep in stroke survivors.

Structural connectome disruption at baseline predicts 6-months post-stroke outcome.

Project description:In this study, models based on quantitative imaging biomarkers of post-stroke structural connectome disruption were used to predict six-month outcomes in various domains. Demographic information and clinical MRIs were collected from 40 ischemic stroke subjects (age: 68.1 ± 13.2 years, 17 female, NIHSS: 6.8 ± 5.6). Diffusion-weighted images were used to create lesion masks, which were uploaded to the Network Modification (NeMo) Tool. The NeMo Tool, using only clinical MRIs, allows estimation of connectome disruption at three levels: whole brain, individual gray matter regions and between pairs of gray matter regions. Partial Least Squares Regression models were constructed for each level of connectome disruption and for each of the three six-month outcomes: applied cognitive, basic mobility and daily activity. Models based on lesion volume were created for comparison. Cross-validation, bootstrapping and multiple comparisons corrections were implemented to minimize over-fitting and Type I errors. The regional disconnection model best predicted applied cognitive (R(2) = 0.56) and basic mobility outcomes (R(2) = 0.70), while the pairwise disconnection model best predicted the daily activity measure (R(2) = 0.72). These results demonstrate that models based on connectome disruption metrics were more accurate than ones based on lesion volume and that increasing anatomical specificity of disconnection metrics does not always increase model accuracy, likely due to statistical adjustments for concomitant increases in data dimensionality. This work establishes that the NeMo Tool's measures of baseline connectome disruption, acquired using only routinely collected MRI scans, can predict 6-month post-stroke outcomes in various functional domains including cognition, motor function and daily activities.

Atrophy of spared gray matter tissue predicts poorer motor recovery and rehabilitation response in chronic stroke.

Project description:Although the motor deficit after stroke is clearly due to the structural brain damage that has been sustained, this relationship is attenuated from the acute to chronic phases. We investigated the possibility that motor impairment and response to constraint-induced movement therapy in patients with chronic stroke may relate more strongly to the structural integrity of brain structures remote from the lesion than to measures of overt tissue damage.Voxel-based morphometry analysis was performed on MRI scans from 80 patients with chronic stroke to investigate whether variations in gray matter density were correlated with extent of residual motor impairment or with constraint-induced movement therapy-induced motor recovery.Decreased gray matter density in noninfarcted motor regions was significantly correlated with magnitude of residual motor deficit. In addition, reduced gray matter density in multiple remote brain regions predicted a lesser extent of motor improvement from constraint-induced movement therapy.Atrophy in seemingly healthy parts of the brain that are distant from the infarct accounts for at least a portion of the sustained motor deficit in chronic stroke.

Intersensory processing of faces and voices at 6 months predicts language outcomes at 18, 24, and 36 months of age.

Project description:Intersensory processing of social events (e.g., matching sights and sounds of audiovisual speech) is a critical foundation for language development. Two recently developed protocols, the Multisensory Attention Assessment Protocol (MAAP) and the Intersensory Processing Efficiency Protocol (IPEP), assess individual differences in intersensory processing at a sufficiently fine-grained level for predicting developmental outcomes. Recent research using the MAAP demonstrates 12-month intersensory processing of face-voice synchrony predicts language outcomes at 18- and 24-months, holding traditional predictors (parent language input, SES) constant. Here, we build on these findings testing younger infants using the IPEP, a more comprehensive, fine-grained index of intersensory processing. Using a longitudinal sample of 103 infants, we tested whether intersensory processing (speed, accuracy) of faces and voices at 3- and 6-months predicts language outcomes at 12-, 18-, 24-, and 36-months, holding traditional predictors constant. Results demonstrate intersensory processing of faces and voices at 6-months (but not 3-months) accounted for significant unique variance in language outcomes at 18-, 24-, and 36-months, beyond that of traditional predictors. Findings highlight the importance of intersensory processing of face-voice synchrony as a foundation for language development as early as 6-months and reveal that individual differences assessed by the IPEP predict language outcomes even 2.5-years later.

Associations between pre-stroke physical activity and physical quality of life three months after stroke in patients with mild disability.

Project description:BackgroundMuch is known about the association between physical activity and the occurrence of stroke. However, the evidence about the correlation between pre-stroke physical activity and post-stroke quality of life remains inconsistent. Thus, there is a high public health relevance to the topic.AimThe aim of this study was to investigate the association between pre-stroke physical activity and physical quality of life after three months.MethodsData arises from 858 patients with stroke included a prospective single-centre observational cohort study in Augsburg, Germany, between September 2018 and November 2019. The participants were recruited at the Department of Neurology and Clinical Neurophysiology, University Hospital of Augsburg after their stroke event. The level of physical activity was determined following the short form of the International Physical Activity Questionnaire at baseline. Physical quality of life was assessed three months after hospital discharge using the German version of the Stroke Impact Scale (SIS). A multiple linear regression model and a quantile regression were carried out.ResultsA total of 497 patients were included in the analysis (mean age 69.6, 58.8% male), 26.2% had a high, 18.9% a moderate and 54.9% a low level of pre-stroke physical activity. Patients with high pre-stroke physical activity had a significantly better physical quality of life three months after stroke in the SIS physical domain (beta = 4.1) and in the SIS subdomains hand function (beta = 5.6), mobility (beta = 4.1) and activities of daily living (beta = 3.7). In the physical domain and the subdomain mobility, the effect was especially strong for persons with low physical quality of life after three months.ConclusionPre-stroke physical activity seems to have an important and positive association with physical quality of life after three months in patients with mild disability. Further studies are needed to confirm these results.
