Traditional data sources are not sufficient for measuring the United Nations Sustainable Development Goals. New and nontraditional sources of data are required. Citizen science is an emerging example of a non-traditional data source that is already making a contribution. In this Perspective, we present a roadmap that outlines how citizen science can be integrated into the formal Sustainable Development Goals reporting mechanisms. Success will require leadership from the United Nations, innovation from National Statistical Offices and focus from the citizen-science community to identify the indicators for which citizen science can make a real contribution.
We studied the role of remote metabolic depressions and pyramidal tract involvement regarding motor recovery following a first hemiparetic ischemic stroke. In 23 patients the regional cerebral glucose metabolism (rCMRGlu) was measured with positron emission tomography and the location and spatial extent of the stroke lesions were assessed by magnetic resonance imaging. Motor impairment during the acute and chronic stages (4 weeks after stroke) was determined by a motor score and recordings of magnetic evoked motor potentials. Twelve patients recovered significantly, whereas 11 patients retained a disabling hemiparesis. In contrast to patients with good motor recovery, rCMRGlu was severely depressed in the thalamus on the lesion side in patients with poor motor recovery. This patient group also showed more severe damage to the pyramidal tract on magnetic resonance images and a more pronounced reduction of the magnetic evoked motor potential amplitude. Neither the size of the stroke lesions nor the spatial extent of the lesional and remote rCMRGlu depressions outside the thalamus correlated with the thalamic hypometabolism and the improvement of the motor score. We conclude that preservation both of parts of the pyramidal tract and of the thalamic circuitry is a major determinant for the quality of hand motor recovery following acute brain ischemia in the adult.
* The perinatal necropsy rate in most of the United Kingdom fails to reach the minimum target of 75% * The quality of many perinatal postmortem examinations is considered poor * Present findings show that necropsy discloses the main cause of death in 18% of perinatal and infants deaths and other new information in a further 8% of deaths * Clinically important information is more likely to emanate from a good quality necropsy * Clinicians should take a more positive attitude towards postmortem examinations net increase in the number classified as dying of a congenital anomaly was only 4% as compared with 10% reported by Duley.'6 The classification was most frequently changed in spontaneous abortions and stillbirths, and so for epidemiological surveys it is particularly important to obtain a necropsy in these settings.This study has shown that necropsy is an invaluable investigation which is currently underused. The rate is likely to increase only if clinicians take a more positive attitude and realise how much clinically relevant information can be obtained from a good quality examination.We thank local convenors, district coordinators, and pathologists for help with data collection, and Professor D P Davies for reviewing the manuscript. We are particularly grateful to the survey administrator, Mrs J M Hopkins, for dedication to the project. The all Wales perinatal survey incorporates the confidential enquiry into stillbirths and deaths in infancy and is funded by the Welsh Office.
We mapped the regional cerebral glucose metabolism (rCMRGlu) in 20 patients suffering from medically refractory focal epilepsy of either left or right mesiotemporal origin (mTLE) during resting wakefulness. After temporal lobectomy, histology demonstrated hippocampal sclerosis in 18 patients. Pixel-by-pixel comparisons with healthy control subjects showed significant (p < 0.001) depressions of the mean rCMRGlu ipsilateral to the epileptic focus in the mesiotemporal region, including the hippocampus and the parahippocampal gyrus and middle temporal gyrus. Additional remote rCMRGlu depressions occurred bilaterally in the fronto-orbital cortex and ipsilaterally in the posterior insula and the thalamus. Patients with left-sided mTLE had additional rCMRGlu depressions in the left inferior frontal gyrus (Broca's region) and superior temporal gyrus at the parietotemporal junction, whereas corresponding rCMRGlu depressions were not present in patients with right mTLE. Neuropsychological testing showed impaired verbal fluency, verbal intelligence, and verbal memory in the left mTLE patients. Correlations of the specific mean rCMRGlu depressions and the neuropsychological deficits suggest that impaired language functions in patients with left mTLE could result from functional changes beyond the temporal lobe.
Quality of life (QOL) reflects the individual's perception of the position within living contexts. This study was done to describe pre- and post-stroke QOLs of stroke survivors. A prospective longitudinal study was done among stroke survivors admitted to 13 hospitals in the western province of Sri Lanka. The calculated sample size was 260. The pre-stroke and post-discharge one-month QOL was gathered using short form-36 (SF-36) QOL tool. SF-36 includes questions on eight domains: general health, physical functioning, pain, role limitation due to physical problems, social functioning, vitality, role limitations due to emotional problems, and mental health. Univariate analysis was followed by determining the independent risk factors through multivariate analysis. The response rate was 81%. The disability was measured by the modified Rankin scale which ranges from 0 (no symptoms) to 6 (fatal outcome). The median (IQR) disability score was 4 (3 to 5). The post-discharge QOL scores were significantly lower than pre-stroke values (p < 0.05). With a higher pre-stroke QOL, younger age was significantly associated in six domains and higher income and better health infrastructure in two domains (p < 0.05). Six factors were determined to be independent risk factors for lower post-discharge QOL scores of SF-36: younger age (for general health and role limitation-physical domains), female gender (for physical functioning and pain domains), lower health infrastructure (for general health, vitality, and mental health domains), lower education (for pain domain), higher disability (for general health, physical functioning, vitality, social functioning, and mental health domains), and hypercholesterolemia (for role limitation-emotional domain). Stroke survivors have not regained their pre-stroke QOL at 1 month following the hospital discharge irrespective of income level and pre-stroke QOL. Higher pre- and post-stroke QOLs are associated with better statuses of social determinants of health.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
