Postmortem measurement of human chorionic gonadotropin in vitreous humor and bile.

Postmortem human chorionic gonadotrophin (HCG) blood assay can confirm postmortem diagnosis of pregnancy or document situations in which HCG levels are elevated. In some cases, however, blood sampling is not possible at autopsy. In this study, HCG was quantified by enzyme-linked fluorescent assay (ELFA) in the bile (n = 5), vitreous humor (n = 4), and postmortem blood (n = 4) of five pregnant women. There were no false negatives in the pregnant subjects (n = 5) or false positives in controls (n = 34), enabling this test to be recommended for routine use in forensic contexts in which the detection of elevated HCG levels could be of interest.

Recommendations for the use of multimodal monitoring in the neurointensive care unit.

PURPOSE OF REVIEW: Multimodal monitoring (MMM) is routinely applied in neurointensive care. Unfortunately, there is no robust evidence on which MMM-derived physiologic variables are the most clinically relevant, how and when they should be monitored, and whether MMM impacts outcome. The complexity is even higher because once the data are continuously collected, interpretation and integration of these complex physiologic events into targeted individualized care is still embryonic. RECENT FINDINGS: Recent clinical investigation mainly focused on intracranial pressure, perfusion of the brain, and oxygen availability along with electrophysiology. Moreover, a series of articles reviewing the available evidence on all the MMM tools, giving practical recommendations for bedside MMM, has been published, along with other consensus documents on the role of neuromonitoring and electroencephalography in this setting. SUMMARY: MMM allows comprehensive exploration of the complex pathophysiology of acute brain damage and, depending on the different configuration of the pathological condition we are treating, the application of targeted individualized care. Unfortunately, we still lack robust evidence on how to better integrate MMM-derived information at the bedside to improve patient management. Advanced informatics is promising and may provide us a supportive tool to interpret physiologic events and guide pathophysiological-based therapeutic decisions.

[Place of volunteers in home care setting for taking care of individuals with Alzheimer's disease related dementia: Qualitative survey in a specialized unit] Place du bénévolat en EHPAD dans la prise en charge des personnes atteintes de la maladie d'Alzheimer ou démences apparentées : enquête qualitative dans une unité protégée.

Objectifs En EHPAD, selon les recommandations de la Haute Autorité de santé (HAS), la prise en charge non médicamenteuse des troubles psychocomportementaux associés à la maladie d'Alzheimer ou aux syndromes apparentés, implique une réorganisation, une formation spécifique du personnel et du temps. Se pose ici la question du rôle des bénévoles dans cette prise en charge. Matériels et méthodes Enquête descriptive à partir de questionnaires distribués aux différents intervenants (bénévoles, professionnels de santé et aidants familiaux) d'une unité protégée de l'EHPAD de la clinique du Diaconat (Colmar, France) et spécifiquement élaborés pour évaluer leur vécu de l'expérience de bénévolat dans la prise en charge des résidents souffrant d'une maladie d'Alzheimer ou d'un syndrome apparenté. Résultats Sur les 101 questionnaires qui ont été remplis, 85,7 % des aidants, 60 % des bénévoles et 42,1 % des professionnels constataient des bénéfices pour eux-mêmes. Les professionnels et les aidants avaient confiance dans l'intervention des bénévoles. Cependant, les bénévoles semblaient manquer de compétence pour le soutien des aidants et dans les techniques de communication avec les résidents. Les points essentiels pour permettre un fonctionnement harmonieux entre les différents intervenants étaient de bien définir préalablement le rôle de bénévoles et d'en informer les autres intervenants, de former les bénévoles à ce rôle et de favoriser la communication entre les bénévoles et les professionnels. Conclusion Cette enquête montre que les bénévoles ont une place aux côtés des équipes soignantes pour participer à la prise en charge non médicamenteuse des personnes atteintes de maladie d'Alzheimer ou syndromes apparentés. Ils ont une position singulière et jouent un rôle complémentaire de celui des soignants et des aidants. Objectives According to the recommendation of the French High Authority of Health (HAS), the non-pharmaceutical management of psycho-behavioural disorders associated with Alzheimer's disease or related disorders in a nursing home, involves reorganization an specific training for staff members and time. This raises the question of the role of volunteering in this approach. Materials and methods A descriptive survey using questionnaires distributed to various stakeholders (volunteers, healthcare professionals and caregivers) of a protected unit of the nursing home of the Diaconat clinic (Colmar, France) and specifically designed to assess their experience of the volunteering in supporting residents suffering from Alzheimer's diseases or related disorders. Results Of the 101 questionnaires that were filled in, 85.7% of caregivers, 60% of volunteers and 42.1% of professionals recorded benefits for themselves. Professionals and informal carers had confidence in the intervention of volunteers. However, volunteers seemed to lack skills to support informal caregivers and specific knowledge about the technique of communicating with residents. The key points to favor harmonious collaborations between the different stakeholders were: to properly define the role of volunteers and to inform other stakeholders about this role previously, and to specifically educate themselves in this task and to promote communication between volunteers and all other professionals. Conclusion This study shows that volunteers have a place alongside medical teams to participate in the non-pharmaceutical treatment for people with Alzheimer's disease or related syndromes. They have a unique position and play a complementary role to that of carers and informal caregivers.

Clinical Utility of the 2 New Scales of the Health of the Nation Outcome Scales for Children and Adolescents (HoNOSCA): A Naturalistic, Prospective Study in a Psychiatric Unit for Adolescents.

OBJECTIVES: The goal of this study was to assess the clinical usefulness of the emotional symptoms (Emo) and externalizing problems (Ext) scales compared with the Total score on the Health of the Nation Outcome Scales for Children and Adolescents (HoNOSCA). METHODS: The HoNOSCA was rated at admission and discharge for 260 adolescent inpatients. The primary outcomes assessed were (a) the sensitivity of the 3 HoNOSCA scores to clinical improvement; and (b) the between diagnoses discriminative value of these scores. RESULTS: Analyses of variances [2 (time: admission vs. discharge) ×5 (diagnostic groups)] revealed a main effect of time for the 3 scores, a main effect of the diagnostic group for the Total and Ext scores, and an interaction effect between time and diagnosis for the Emo score. A moderate correlation was observed between the change in Ext and Emo scores between admission and discharge. DISCUSSION: These 2 new scales of the HoNOSCA demonstrated good clinical utility and the ability to assess different aspects of clinical improvements. A significant discriminative value of both scores was observed. SIGNIFICANT OUTCOMES: The clinical utility of the 2 new scales on the HoNOSCA was established. These 2 new scales provided a sensitive measure of clinical outcome for assessing improvement between admission and discharge on a psychiatric inpatient unit for adolescents, regardless of diagnostic group, and captured additional information about clinical improvements. Adolescents with psychosis and conduct disorders presented with higher externalizing symptoms than those with other disorders, as rated on the HoNOSCA, at admission and discharge. The Emo score differentiated between clinical improvement in patients with psychosis versus eating disorders. LIMITATIONS: The sample in this study represented a homogeneous population of adolescent inpatients, so that further research is needed before these findings can be generalized to outpatients. In addition, the small number of patients in some diagnostic groups did not allow for their inclusion in some of the statistical analyses.

Single breath-hold 3D measurement of left atrial volume using compressed sensing cardiovascular magnetic resonance and a non-model-based reconstruction approach.

BACKGROUND: Left atrial (LA) dilatation is associated with a large variety of cardiac diseases. Current cardiovascular magnetic resonance (CMR) strategies to measure LA volumes are based on multi-breath-hold multi-slice acquisitions, which are time-consuming and susceptible to misregistration. AIM: To develop a time-efficient single breath-hold 3D CMR acquisition and reconstruction method to precisely measure LA volumes and function. METHODS: A highly accelerated compressed-sensing multi-slice cine sequence (CS-cineCMR) was combined with a non-model-based 3D reconstruction method to measure LA volumes with high temporal and spatial resolution during a single breath-hold. This approach was validated in LA phantoms of different shapes and applied in 3 patients. In addition, the influence of slice orientations on accuracy was evaluated in the LA phantoms for the new approach in comparison with a conventional model-based biplane area-length reconstruction. As a reference in patients, a self-navigated high-resolution whole-heart 3D dataset (3D-HR-CMR) was acquired during mid-diastole to yield accurate LA volumes. RESULTS: Phantom studies. LA volumes were accurately measured by CS-cineCMR with a mean difference of -4.73 ± 1.75 ml (-8.67 ± 3.54%, r2 = 0.94). For the new method the calculated volumes were not significantly different when different orientations of the CS-cineCMR slices were applied to cover the LA phantoms. Long-axis "aligned" vs "not aligned" with the phantom long-axis yielded similar differences vs the reference volume (-4.87 ± 1.73 ml vs. -4.45 ± 1.97 ml, p = 0.67) and short-axis "perpendicular" vs. "not-perpendicular" with the LA long-axis (-4.72 ± 1.66 ml vs. -4.75 ± 2.13 ml; p = 0.98). The conventional bi-plane area-length method was susceptible for slice orientations (p = 0.0085 for the interaction of "slice orientation" and "reconstruction technique", 2-way ANOVA for repeated measures). To use the 3D-HR-CMR as the reference for LA volumes in patients, it was validated in the LA phantoms (mean difference: -1.37 ± 1.35 ml, -2.38 ± 2.44%, r2 = 0.97). Patient study: The CS-cineCMR LA volumes of the mid-diastolic frame matched closely with the reference LA volume (measured by 3D-HR-CMR) with a difference of -2.66 ± 6.5 ml (3.0% underestimation; true LA volumes: 63 ml, 62 ml, and 395 ml). Finally, a high intra- and inter-observer agreement for maximal and minimal LA volume measurement is also shown. CONCLUSIONS: The proposed method combines a highly accelerated single-breathhold compressed-sensing multi-slice CMR technique with a non-model-based 3D reconstruction to accurately and reproducibly measure LA volumes and function.
