Follow-up Assessment Of Patients Research Articles

Myocarditis Associated with COVID-19 Vaccination.

Myocarditis after the COVID-19 vaccine is one of the important adverse events following immunization, observed mainly after mRNA-based vaccines. Importantly, post-vaccination myocarditis was less common than myocarditis after SARS-CoV-2 infection, as it was scored at 19.7 per 1,000,000 doses and 2.76 per 1000 infections. Predominantly, its course was benign and, compared with the myocarditis after COVID-19 infection, significantly fewer patients developed heart failure or died among patients with post-vaccination myocarditis. The group at highest risk of myocarditis related to COVID-19 vaccination were young males who received a second dose of an mRNA vaccine. It was observed that, among mRNA vaccines, specifically mRNA-1273 was associated with a higher risk of myocarditis. The mechanism underlying myocarditis after COVID-19 vaccination is still under investigation and certain processes are being considered. Currently, some follow-up assessments of patients who developed vaccine-induced myocarditis are available and suggest a favorable prognosis. The aim of this review is to discuss the most recent data on myocarditis after COVID-19 vaccination considering its epidemiology, clinical presentation, diagnosis, management, relative risk of myocarditis compared with SARS-CoV-2 infection, potential underlying mechanism, and follow-up data of patients who developed post-vaccination myocarditis.

Predicting postoperative hypocortisolism in patients with non-aldosterone-producing adrenocortical adenoma: a retrospective single-centre study

BackgroundLimited information exists on postoperative hypocortisolism and hypothalamus–pituitary–adrenal axis recovery in patients with adrenal incidentaloma following unilateral adrenalectomy. We evaluated frequency of postoperative hypocortisolism and predictors for recovery in non-aldosterone-producing adrenocortical adenoma patients after unilateral adrenalectomy.MethodsA retrospective analysis of 32 adrenal incidentaloma patients originally included in the ITACA trial (NCT04127552) with confirmed non-aldosterone-producing adrenocortical adenoma undergoing unilateral adrenalectomy from September 2019 to April 2023 was conducted. Preoperative assessments included adrenal MRI, anthropometrics, evaluation of comorbidities, adrenal function assessed via ACTH, urinary free cortisol, and 1 mg dexamethasone suppression test. ACTH and serum cortisol or Short Synacthen test were performed within 6 days, 6 weeks, 6 months, and a year after surgery.ResultsSix days postoperative, 18.8% of patients had normal adrenal function. Among those with postoperative hypocortisolism, 53.8% recovered by 6 weeks. Patients with earlier adrenal recovery (6 weeks) had lower preoperative 1 mg dexamethasone suppression test (median 1 mg dexamethasone suppression test 76.2 [61.8–111.0] nmol/L vs 260.0 [113.0–288.5] nmol/L, p < 0.001). Univariate analysis showed preoperative 1 mg dexamethasone suppression test negatively related with baseline ACTH levels (r = − 0.376; p = 0.041) and negatively associated with the 6-week baseline (r = − 0.395, p = 0.034) and 30-min cortisol levels during Short Synacthen test (r = − 0.534, p = 0.023). Logistic regression analysis demonstrated preoperative 1 mg dexamethasone suppression test as the only biochemical predictor for 6-week adrenal recovery: ROC curve identified a 1 mg dexamethasone suppression test threshold of 131 nmol/L predicting 6-week recovery with 89.5% sensitivity and 72.7% specificity (AUC 0.87; 95% CI 66.9–98.7, p < 0.001). Other preoperative assessments (tumor size, ACTH levels and anthropometrics) were not associated with postoperative hypothalamus–pituitary–adrenal axis function, but the presence of diabetes was associated with a lower probability of recovery (OR = 24.55, p = 0.036). ACTH levels increased postoperatively in all patients but did not predict hypothalamus–pituitary–adrenal axis recovery.ConclusionsThe preoperative 1 mg dexamethasone suppression test cortisol value and presence of diabetes are the only relevant predictor of hypothalamus–pituitary–adrenal axis recovery in patients with non-aldosterone- producing adrenocortical adenoma undergoing surgery, regardless other clinical and biochemical variables. Notably, pre- and postoperative ACTH levels did not predict hypothalamus–pituitary–adrenal axis recovery. These findings point towards the potential for saving resources by optimizing their allocation during follow-up assessments for patients with non-aldosterone-producing adrenocortical adenoma undergoing unilateral adrenalectomy.

Deep Learning-Based Analysis of Aortic Morphology From Three-Dimensional MRI.

Quantification of aortic morphology plays an important role in the evaluation and follow-up assessment of patients with aortic diseases, but often requires labor-intensive and operator-dependent measurements. Automatic solutions would help enhance their quality and reproducibility. To design a deep learning (DL)-based automated approach for aortic landmarks and lumen detection derived from three-dimensional (3D) MRI. Retrospective. Three hundred ninety-one individuals (female: 47%, age = 51.9 ± 18.4) from three sites, including healthy subjects and patients (hypertension, aortic dilation, Turner syndrome), randomly divided into training/validation/test datasets (N = 236/77/78). Twenty-five subjects were randomly selected and analyzed by three operators with different levels of expertise. 1.5-T and 3-T, 3D spoiled gradient-recalled or steady-state free precession sequences. Reinforcement learning and a two-stage network trained using reference landmarks and segmentation from an existing semi-automatic software were used for aortic landmark detection and segmentation from sinotubular junction to coeliac trunk. Aortic segments were defined using the detected landmarks while the aortic centerline was extracted from the segmentation and morphological indices (length, aortic diameter, and volume) were computed for both the reference and the proposed segmentations. Segmentation: Dice similarity coefficient (DSC), Hausdorff distance (HD), average symmetrical surface distance (ASSD); landmark detection: Euclidian distance (ED); model robustness: Spearman correlation, Bland-Altman analysis, Kruskal-Wallis test for comparisons between reference and DL-derived aortic indices; inter-observer study: Williams index (WI). A WI 95% confidence interval (CI) lower bound >1 indicates that the method is within the inter-observer variability. A P-value <0.05 was considered statistically significant. DSC was 0.90 ± 0.05, HD was 12.11 ± 7.79 mm, and ASSD was 1.07 ± 0.63 mm. ED was 5.0 ± 6.1 mm. A good agreement was found between all DL-derived and reference aortic indices (r >0.95, mean bias <7%). Our segmentation and landmark detection performances were within the inter-observer variability except the sinotubular junction landmark (CI = 0.96;1.04). A DL-based aortic segmentation and anatomical landmark detection approach was developed and applied to 3D MRI data for achieve aortic morphology evaluation. 3 TECHNICAL EFFICACY: Stage 2.

Residual risk identified in routine noninvasive follow-up assessments in pulmonary arterial hypertension.

The 2022 ESC/ERS guidelines on pulmonary hypertension recommend noninvasive risk assessments based on three clinical variables during follow-up in patients with pulmonary arterial hypertension (PAH). We set out to test whether residual risk can be captured from routinely measured noninvasive clinical variables during follow-up in PAH. We retrospectively studied 298 incident PAH patients from a German pulmonary hypertension centre who underwent routine noninvasive follow-up assessments including exercise testing, echocardiography, electrocardiography, pulmonary function testing and biochemistry. To select variables, we used least absolute shrinkage and selection operator (LASSO)-regularised Cox regression models. Outcome was defined as mortality or lung transplant after first follow-up assessment. 12 noninvasive variables that were associated with outcomes in a training sub-cohort (n=208) after correction for multiple testing entered LASSO modelling. A model combining seven variables discriminated 1-year (area under the curve (AUC) 0.83, 95% confidence interval (CI) 0.68-0.99, p=8.4×10-6) and 3-year (AUC 0.81, 95% CI 0.70-0.92, p=2.9×10-8) outcome status in a replication sub-cohort (n=90). The model's discriminatory ability was comparable to that of the guideline approach in the replication sub-cohort. From the individual model components, World Health Organization functional class, 6-min walking distance and the tricuspid annular plane systolic excursion to systolic pulmonary arterial pressure (TAPSE/sPAP) ratio were sensitive to treatment initiation. Addition of TAPSE/sPAP ratio to the guideline approach numerically increased its ability to discriminate outcome status. Our real-world data suggest that residual risk can be captured by noninvasive clinical procedures during routine follow-up assessments in patients with PAH and highlights the potential use of echocardiographic imaging to refine risk assessment.

Retinal vessel dynamics analysis as a surrogate marker for raised intracranial pressure in patients with suspected idiopathic intracranial hypertension.

Retinal vessel dynamics analysis has proven to be a viable, non-invasive surrogate marker for increased intracranial pressure. We aimed to test this method in patients with suspected idiopathic intracranial hypertension. Patients with suspected idiopathic intracranial hypertension were prospectively enrolled for hand-held fundus-videography during diagnostic lumbar puncture. After extracting optic disc images, peripapillary arteriole-to-venule-ratios were measured using machine-learning algorithms with manual identification control. A general linear model was applied to arteriole-to-venule-ratios and corresponding lumbar opening pressures to estimate cerebrospinal fluid pressure. Twenty-five patients were included with a significant difference in arteriole-to-venule-ratio between patients with (n = 17) and without (n = 8) idiopathic intracranial hypertension (0.78 ± 0.10 vs 0.90 ± 0.08, p = 0.006). Arteriole-to-venule-ratio correlated inversely with lumbar opening pressure (slope regression estimate -0.0043 (95% CI -0.0073 to -0.0023), p = 0.002) and the association was stronger when lumbar opening pressure exceeded 15 mm Hg (20 cm H2O) (slope regression estimate -0.0080 (95% CI -0.0123 to -0.0039), p < 0.001). Estimated cerebrospinal fluid pressure predicted increased lumbar opening pressure >20 mm Hg (27 cm H2O) with 78% sensitivity and 92% specificity (AUC 0.81, p = 0.02). A stand-alone arteriole-to-venule-ratio measurement predicting lumbar opening pressure >20 mm Hg (27 cm H2O) was inferior with a 48% sensitivity and 92% specificity (AUC 0.73, p = 0.002). Retinal vessel dynamics analysis with the described model for estimating cerebrospinal fluid pressure is a promising non-invasive method with a high sensitivity and specificity for detecting elevated intracranial pressure at follow-up assessments of patients with confirmed idiopathic intracranial hypertension if initial lumbar opening pressure and arteriole-to-venule-ratio data are available.

PP77 Safety, Effectiveness, And Cost Effectiveness Of Telemedicine In Neurological Diseases

IntroductionTelemedicine has been introduced in health services, but uncertainties about the real value of this strategy in the management of neurological diseases remain.MethodsA systematic review was undertaken of available scientific literature on the safety, effectiveness, and cost effectiveness of telemedicine combined with in-person visits, compared with usual care, for the treatment and follow-up assessment of patients with neurological diseases. The overall effect size for each neurological disease was estimated using meta-analysis. An economic analysis was performed from the societal and Spanish healthcare system perspectives.ResultsTwo economic studies were included for cost effectiveness and 25 randomized controlled trails (n=8,976 patients) were included for the effectiveness and safety assessment (11 on cerebrovascular diseases, four on Parkinson’s disease, three on multiple sclerosis, two on epilepsy, and one each on brain damage, dementia, spina bifida, migraine, and cerebral palsy). The types of telemedicine evaluated included: virtual visits (11 studies); telerehabilitation (seven studies); telephone calls (three studies); smartphone apps (two studies); and online software for computers (two studies). Subgroup analysis by type of telemedicine indicated no discernible effect for telemedicine combined with in-person visits on most of the outcomes analyzed for the various neurological diseases. Given the heterogeneity of diseases, types of telemedicine, and the results observed, a cost-minimization analysis was conducted. Combining telemedicine with in-person visits would cost EUR 2.55 per patient from the perspective of the healthcare system, but it would result in cost savings (EUR 27.34 per patient) from the societal perspective.ConclusionsThe safety and effectiveness of combining in-person visits with telemedicine was similar to that of usual care, but it could be a cost-saving strategy in Spain from a societal perspective.

Follow-up assessment of patients with Pure Neural Leprosy in a reference center in Rio de Janeiro-Brazil.

IntroductionPure Neural Leprosy (PNL) is a rare clinical form of leprosy in which patients do not present with the classical skin lesions but have a high burden of the disability associated with the disease. Clinical characteristics and follow up of patients in PNL are still poorly described in the literature.ObjectiveThis paper aims to describe the clinical, electrophysiological and histopathological characteristics of PNL patients, as well as their evolution after multidrug therapy (MDT).MethodsFifty-two PNL patients were selected. Clinical, nerve conduction studies (NCS), histopathological and anti-PGL-1serology were evaluated. Patients were also assessed monthly during the MDT. At the end of the MDT, all of the patients had a new neurological examination and 44 were submitted to another NCS.ResultsParesthesia was the complaint most frequently reported by patients, and in the neurological examination the most common pattern observed was impairment in sensory and motor examination and a mononeuropathy multiplex. Painful nerve enlargement, a classical symptom of leprosy neuropathy, was observed in a minority of patients and in the motor NCS axonal injuries, alone or in combination with demyelinating features, were the most commonly observed. 88% of the patients did not present any leprosy reaction during MDT. There was no statistically significant difference between the neurological examinations, nor the NCS pattern, performed before and after the MDT.DiscussionThe classical hallmarks of leprosy neuropathy are not always present in PNL making the diagnosis even more challenging. Nerve biopsy is an important tool for PNL diagnosis as it may guide therapeutic decisions. This paper highlights unique characteristics of PNL in the spectrum of leprosy in an attempt to facilitate the diagnosis and management of these patients.

Cognitive outcome following bilateral subthalamic nucleus deep brain stimulation for Parkinson's disease-a comparative observational study in Indian patients.

Deep brain stimulation (DBS) of the subthalamic nucleus (STN) improves motor symptoms and motor complications of Parkinson's disease (PD). The intervention is expected to result in some cognitive changes, the nature of which is not uniform across the studies which have reported them. PD itself is associated with progressive cognitive decline and hence longitudinal follow-up studies with medically managed control group of patients are needed to explore the cognitive deficits attributable to DBS. We conducted a prospective comparative observational study to assess the effects of bilateral STN DBS on cognition. Cognitive functions were assessed at baseline and after a minimum of two years after surgery, and compared with baseline and follow-up assessments in patients on medical management alone. Thirty-four patients with PD who underwent bilateral STN DBS and thirty-four medically managed patients participated in the study. At a mean follow-up of around 33months, we found a significant decline in verbal fluency scores in the DBS group compared to those on medical management alone (1.15 ± 1.23 vs 0.59 ± 0.93, p = 0.034) and a trend for decline was noted in digit span test. There was no difference in the performance in tests addressing other cognitive domains, or tests of global cognitive function. No patient developed dementia. Motor functions and activities of daily living (ADL) were significantly better in the surgical group. STN DBS results in minor deficits in executive functions, particularly verbal fluency. These may be inconsequential, considering the marked improvement in motor functions and ADL.

Post-traumatic Stress Disorder Among COVID-19 Survivors at 3-Month Follow-up After Hospital Discharge.

BackgroundPost-traumatic stress disorder (PTSD) is a severe but treatable mental disorder that develops after a life-threatening traumatic event. Coronavirus disease 19 (COVID-19) hospitalisation is a potentially traumatic experience, especially in severe cases. Furthermore, the unprecedented context of the severe acute respiratory syndrome coronavirus 2 pandemic, with daily media bombardment about COVID-19 mortality, may have amplified life-threatening perception also in patients with moderate infection. The aim of this study was to assess the prevalence and risk factors of PTSD at 3-month follow-up in patients hospitalised for COVID-19 infection.DesignIn this cohort follow-up study conducted in a large Italian academic COVID-19 hospital, 115 recruited survivors were contacted by telephone 3 months after discharge to home care. The Posttraumatic Stress Disorder Checklist for DSM-5 was administered. Multivariate logistic regression models were used to analyse risk factors for the development of PTSD.Key ResultsA total of 10.4% of the sample received a PCL-5-based diagnosis of PTSD. Other 8.6% of the sample received a diagnosis of subthreshold PTSD, which leads to significant levels of distress and impairment. Multivariate regression analysis indicated that previous psychiatric diagnosis (odds ratio (OR) = 6.3, 95% confidence interval (CI): 3.7–78.6, p < 0.001) and obesity (OR = 3.51, 95% CI: 1.4–857.9, p = 0.03) were risk factors for developing PTSD. Chronic pulmonary diseases approached significance as a risk factor (OR = 6.03, 95% CI: 1.0–37.1, p = 0.053). Male sex was a protective factor (OR=0.04, 95% CI: 0.0–0.041, p = 0.007).ConclusionsPTSD and subthreshold PTSD rates in patients hospitalised for COVID-19 are worrying. Female sex and pre-existing mental disorders are established risk factors for PTSD, while the prospective association with obesity needs further investigation. Clinicians treating COVID-19 should consider screening for PTSD at follow-up assessments in patients discharged from the hospital.

Assessment of diaphragm dysfunction during cardiac rehabilitation after heart surgery: the role of ultrasound imaging

Abstract Background Diaphragm dysfunction is a frequent and underdiagnosed complication of cardiac surgery. It can cause dyspnoea, decreased exercise performance and, in more severe cases, respiratory failure. Ultrasonography (US) is a valuable, non-invasive technique for the assessment of diaphragm function. Only few trials have been conducted using US to evaluate diaphragm functional recovery after cardiovascular rehabilitation (CR). Purpose The aim of the study was to assess with US the incidence of diaphragm dysfunction after heart surgery and to define the impact of an inpatient CR programme on diaphragm functional recovery. Methods We performed a single-centre prospective cohort study, enrolling 185 patients hospitalized in our CR unit: 99 patients underwent mitral valve repair or replacement, 28 tricuspid valve repair or replacement, 53 aortic valve replacement, 30 coronary artery bypass grafting, 59 combined surgery and 14 other surgical procedures. Diaphragm US was performed at admission and after 10 rehabilitative sessions. We assess the following parameters on quiet breathing: excursion, time of inspiration, time of a respiratory cycle and contraction velocity (slope) in M-mode on the right anterior subcostal projections and thickening fraction (TF) in B-mode on the right intercostal projections. TF was defined as [(thickness at end inspiration–thickness at end expiration)/thickness at end expiration]. Results The median excursion at admission was 1.6 cm. Patients with excursion &amp;lt;2 cm (lower limit for the general population) were considered with diaphragm dysfunction. Following cardiac surgery, the incidence of diaphragm dysfunction was 70.8%. Patients with excursion &amp;lt;2 cm at admission gained an important benefit from CR, with a significant improvement in TF (p&amp;lt;0.001), excursion (p&amp;lt;0.001), time of inspiration (p&amp;lt;0.001), time of a respiratory cycle (p&amp;lt;0.001) and slope (p&amp;lt;0.001). Conversely, in patients with excursion ≥2 cm there was no significant improvement in slope (p=0.539) and excursion (p=0.179). At the final assessment, diaphragm function recovered in 50.5% of the patients, whilst 49.5% had a failure of recovery (excursion relative change between admission and discharge &amp;lt;33%). The multivariate analysis identified combined surgery (OR 3.08; 95% CI 1.59–5.99, p=0.001) and post-surgical pneumothorax (OR 3.05; 95% CI 1.23–7.55, p=0.036) as independent predictors of failure of diaphragm function recovery. Conclusions US might be a valuable tool for initial and follow-up assessment of patients after cardiac surgery. CR has been shown to be an effective strategy to improve diaphragm parameters in patients with post-surgical dysfunction. Patients undergoing combined surgery or developing post-surgical pneumothorax might benefit from a personalised rehabilitation programme to improve diaphragm function.

Validation of the Telephone-Based Application of the ABILHAND for Assessment of Manual Ability After Stroke.

Telephone-based assessment may be a valuable and cost-effective approach to improve monitoring and follow-up assessments in patients and research participants. Telephone-based assessment may be of particular value during times when it is important to reduce in-person contract, such as during the Covid-19 pandemic. The purpose of this study was to investigate concurrent validity of the telephone-based administration of the ABILHAND for the assessment of manual ability in individuals with stroke. Using a cross-sectional study design, participants with stroke were invited to answer the ABILHAND questionnaire on 2 randomized occasions, face to face and by telephone, 5 to 7 days apart. The mean difference (MD) between the interviews was calculated (95% confidence interval [95% CI]) to investigate the concurrent validity. Intraclass correlation (ICC) and weighted κ coefficients were used to investigate the agreement between face-to-face and telephone-based administration. One hundred two participants (50 men; mean age = 65 years, SD = 13 years) were included. No significant differences were observed between the mean scores obtained with face-to-face and telephone-based administration of the ABILHAND (MD = -0.06; 95% CI, -0.72 to 0.60). Very high agreement was found between face-to-face and telephone-based administration (ICC = 0.90; 95% CI, 0.85 to 0.93) on the ABILHAND total scores. Most of the individual items had moderate or substantial κ agreement. Telephone-based administration of the ABILHAND is valid for the assessment of manual ability after stroke. Clinicians and researchers may use the ABILHAND for monitoring manual ability in persons with stroke and/or screening potential research participants.Video Abstract available for more insights from the authors (see the Video, Supplemental Digital Content 1, http://links.lww.com/JNPT/A318).

An Electronic Medication Module to Improve Health Literacy in Patients With Type 2 Diabetes Mellitus: Pilot Randomized Controlled Trial.

BackgroundIn primary care, patients play a crucial role in managing care processes and handling drug treatment. A decisive factor for success is their health literacy, and several interventions have been introduced to support patients in fulfilling their responsibility.ObjectiveThe aim of this study is to assess the influence of such an intervention (ie, a medication module) within a patient-led electronic health record on patients’ health literacy.MethodsWe conducted a randomized controlled study among community-dwelling patients with type 2 diabetes mellitus. Patients were recruited from primary care practices. After randomization, patients either had access to an internet-based medication module allowing them to store their medication information, look up drug information, and print a medication schedule (intervention group), or they received an information brochure on the importance of medication schedules (control group). After 4-8 weeks, all patients were invited to attend a structured medication review (ie, follow-up visit). Data were collected via questionnaires before the start of the intervention and during the follow-up visit. The main outcome measure was the mean difference in health literacy between baseline and follow-up assessments of patients in the control and intervention groups.ResultsOf 116 recruited patients, 107 (92.2%) completed the follow-up assessment and were eligible for intention-to-treat analyses. Only 73 patients, of which 29 were in the intervention group, followed the study protocol and were eligible for per-protocol analysis. No differences in overall health literacy were observed in either the intention-to-treat or in the per-protocol cohorts. Reasons for a null effect might be that the cohort was not particularly enriched with participants with low health literacy, thus precluding measurable improvement (ie, ceiling effect). Moreover, the success of implementation was considered poor because both the correct application of the study procedure (ie, randomization according to the protocol and dropout of 29 patients) and the actual interaction with the medication module was modest (ie, dropout of 9 patients).ConclusionsThe conduct of this randomized controlled study was challenging, leaving it open whether inadequate implementation, too short of a duration, or insufficient efficacy of the intervention, as such, contributed to the null effect of this study. This clearly outlines the value of piloting complex interventions and the accompanying process evaluations.

P4385Diaphragm dysfunction following cardiac surgery: role of ultrasound imaging for initial and follow-up assessment during cardiac rehabilitation

Abstract Background Diaphragm dysfunction is a common complication of cardiac surgery, often underdiagnosed. Ultrasonography (US) is a promising technique for diaphragmatic assessment. Few trials have been conducted using US after heart surgery and no clear data exist on the recovery of diaphragm function after cardiovascular rehabilitation (CR). Purpose The aim of this study is to evaluate post-cardiac surgery diaphragm dysfunction using US and to assess the impact of an inpatient CR programme on its functional recovery. Methods In a single-centre prospective cohort study 97 consecutive patients hospitalised in our CR Unit were enrolled. 14 patients underwent aortic valve replacement, 38 mitral valve repair or replacement, 14 coronary artery bypass grafting (CABG), 22 combined surgery, and 9 other surgical interventions. We performed diaphragm US at admission and after 10 rehabilitative sessions. The following parameters were assessed: thickening fraction (TF) in B-mode on the right intercostal projections, and excursion, time of inspiration, time of a respiratory cycle and contraction velocity in M-mode on right anterior subcostal projections. Results After cardiac surgery, the incidence of diaphragm dysfunction and paralysis were 60% and 1%, respectively. Patients with TF &lt;20% at admission showed a significant improvement in TF (13.30%, IQR 8.69–17.39 vs 27.27%, IQR 21.05–31.58; p&lt;0.001), excursion (1.67cm, IQR 1.3–2.1 vs 2.23cm, IQR 1.9–2.7; p&lt;0.001), time of inspiration (0.9s, IQR 0.9–1.07 vs 1.01s, IQR 0.87–1.13; p=0.005), time of a respiratory cycle (2.67s, IQR 2.38–3.05 vs 3.07s, IQR 2.68–3.35; p&lt;0.001) and velocity (1.81cm/s, IQR 1.14–2.33 vs 2.24cm/s, IQR 1.92–2.76; p&lt;0.001). On the contrary, in patients with a TF&gt;20%, no additional improvement was observed. In both groups, there was a significant improvement in the parameters of physical performance. In particular, in the group with a TF&lt;20%, the distance covered during the 6MWT (300m, IQR 205–370 vs 555m, IQR 450–612; p&lt;0.001) and the energy cost of physical activity (2.60, IQR 2.13–2.92 vs 4.09, IQR 3.44–4.50; p&lt;0.001) increased while the perception of exertion (Borg Scale 11, IQR 11–13 vs 13, IQR 12–13; p=0.011) was reduced. At the 10th day assessment, 51.5% of the total population had a recovery of diaphragm function, whilst 48.5% had a failure of recovery (TF relative change between admission and discharge &lt;60%). The multivariate analysis identified CABG as an independent predictor of failure of diaphragm recovery (OR 5.44; CI 1.10–26.84, p=0.037). Conclusion US might be a valuable part of routine clinical practice for initial and follow-up assessment of patients after open-heart surgery. CR showed to be an effective strategy to improve diaphragm parameters in patients with post-surgical dysfunction. Progressive evaluation of diaphragm function may drive personalised rehabilitation programmes.

Development and Validation of a Computerized Alternating Attention Test (CAAT) in Patients With Schizophrenia

Abstract Date Presented 04/05/19 The Computerized Alternating Attention Test (CAAT) assesses alternating attention regularly in clinic and follow-up assessments in patients with schizophrenia. When performing the CAAT, subjects were required to alternately judge two types of rules: digit and shape. A shorter time for completing the CAAT indicates better alternating attention. Our validation of CAAT indicated that the CAAT had the acceptable test-retest agreement, negligible practice effect, and acceptable concurrent validity.

Quantitative Follow-Up Assessment of Patients with Interstitial Lung Disease by 3D-Curved High-Resolution CT Imaging Parallel to the Chest Wall.

ABSTRACTWe evaluated the progression of interstitial lung disease (ILD) by three-dimensional curved high-resolution computed tomography (3D-cHRCT) at a constant depth from the chest wall and compare the results to pulmonary function test (PFT) results on a follow-up assessment. We reviewed the patients with ILD who underwent HRCT and concurrent PFTs at least twice from April 2008 to December 2014. Forty-five patients with ILD were enrolled. 3D-cHRCT images of the lung at various depths from the chest wall were reconstructed, and total area (TA), high-attenuation area (HAA) >-500 HU, and %HAA ([HAA/TA] × 100) were calculated. The TA, HAA, and %HAA ratios (follow-up to baseline) were assessed for use in the diagnosis of physiologically progressive ILD (defined as; forced vital capacity [FVC] ratio <0.9 or %diffusing capacity of the lung for carbon monoxide [%DLCO] ratio <0.85 [follow-up to baseline]). Of all ratios obtained from 3D-cHRCT images at 5–30mm depths, the %HAA ratio at 20-mm had the largest area under the receiver operating characteristic curve (0.815, 95 % confidence interval 0.677–0.953). By univariate logistic regression analysis, TA, HAA, and %HAA ratios at 20-mm showed significant correlations with physiologically progressive ILD. 3D-cHRCT imaging performed in parallel with the chest wall offers novel quantitative parameters that are useful for following ILD.

PREDICTORS OF A FUTURE SEVERE ASTHMA EXACERBATION AFTER A DECADE FOLLOW-UP: RESULTS FROM TENOR II

Introduction Studies have shown that a prior asthma exacerbation is the strongest predictor of a future exacerbation. Using long-term observational data, we examined whether this association persists using 10-year follow-up data. Methods TENOR II was a multicenter, observational study with a cross-sectional single follow-up assessment of patients with severe/difficult-to-treat asthma more than 10 years after enrollment in the TENOR I study. Multivariable logistic regression assessed predictors of an ATS severe exacerbation at TENOR II using TENOR II variables, with the exception of a severe exacerbation from TENOR I, defined as 1 or more corticosteroid bursts within the 3 months before enrollment. Results A total of 288 patients were included. Mean age was 58.4 (16.0) years, 66.7% were female. Nearly half (46.9%) were obese and a quarter (25.0%) had ever smoked. Geometric mean of total IgE level was 68.9 IU/mL and mean eosinophil level was 197.6 (144.9) µL. Mean % predicted pre- and post-bronchodilator FEV1 was 72.9% and 78.3%, respectively. 71.2% of patients used combined ICS/LABA medication. Statistically significant predictors of a severe exacerbation were combined ICS/LABA use (odds ratio (OR) 3.5, 95% CI: 1.5, 8.0; p=0.004), a severe exacerbation at TENOR I (OR 2.5, 95% CI: 1.3, 4.8; p=0.007), and % predicted post-bronchodilator FEV1 (OR 1.2, 95% CI: 1.0, 1.4; p=0.046). Conclusions A prior severe exacerbation remains a predictor of a future exacerbation in patients with severe/difficult-to-treat asthma after more than a decade. Combined ICS/LABA use, and low post-bronchodilator lung function also increased the odds of a future exacerbation.

Effectiveness of a Blended Multidisciplinary Intervention for Patients with Moderate Medically Unexplained Physical Symptoms (PARASOL): Protocol for a Cluster Randomized Clinical Trial.

BackgroundMedically unexplained physical symptoms are an important health problem in primary care, with a spectrum from mild to chronic. The burden of chronic medically unexplained physical symptoms is substantial for patients, health care professionals, and society. Therefore, early identification of patients with moderate medically unexplained physical symptoms is needed in order to prevent chronicity. The preventive screening of medically unexplained physical symptoms (PRESUME) screening method was developed using data from the electronic medical record of the patients' general practitioner and demonstrated its prognostic accuracy to identify patients with moderate medically unexplained physical symptoms. In the next step, we developed a proactive blended and integrated mental health and physical therapy intervention program (PARASOL) to reduce complaints of moderate medically unexplained physical symptoms, stimulate self-management, and prevent chronicity.ObjectiveThe primary objective of this study is to investigate the effectiveness of the blended PARASOL intervention on the impact of symptoms and quality of life in patients with moderate medically unexplained physical symptoms compared with usual care. Secondary objectives are to study the effect on severity of physical and psychosocial symptoms, general health, physical behavior, illness perception, and self-efficacy in patients with moderate medically unexplained physical symptoms as well as to determine the cost-effectiveness of the program.MethodsThis paper presents the study protocol of a multicenter cluster randomized clinical trial. Adult patients with moderate medically unexplained physical symptoms will be identified from electronic medical record data using the PRESUME screening method and proactively recruited for participation in the study. Cluster randomization will be performed at the level of the participating health care centers. In total 248 patients with moderate medically unexplained physical symptoms (124 patients per arm) are needed. The PARASOL intervention is a 12-week blended primary care program consisting of 4 face-to-face consultations with the mental health nurse and 5 physical therapy sessions, supplemented with a Web-based program. The Web-based program contains (1) information modules and videos on self-management and educative themes, (2) videos and instructions on prescribed home exercises, and (3) assignments to gradually increase the physical activity. The program is directed at patients’ perception of symptoms as well as modifiable prognostic risk factors for chronicity using therapeutic neuroscience education. It encourages self-management, as well as an active lifestyle using a cognitive behavioral approach and graded activity. Primary outcomes are impact of symptoms and quality of life. Secondary outcomes are severity of physical and psychosocial symptoms, general health, physical behavior, illness perceptions, self-efficacy, and cost-effectiveness. All measurements will be performed at baseline, 3 and 12 months after baseline. Retrospective cost questionnaires will also be sent at 6 and 9 months after baseline and these will be used for the cost-effectiveness analysis.ResultsThe intervention has been developed, and the physical therapists and mental health nurses in the participating experimental health care centers have received two days of training on the content of the blended PARASOL intervention. The recruitment of health care centers started in June 2016 and inclusion of patients began in March 2017. Follow-up assessments of patients are expected to be completed in March 2019.ConclusionsThis study is the first randomized clinical trial to determine the effectiveness (including cost-effectiveness) of a proactive, blended, and integrated mental health and physical therapy care program for patients with moderate medically unexplained physical symptoms. The findings will help to improve the treatment for patients with moderate medically unexplained physical symptoms and prevent chronicity.Trial RegistrationNetherlands Trial Register NTR6755; http://www.trialregister.nl/trialreg/admin/rctview.asp?TC=6755 (Archived by WebCite at http://www.webcitation.org/6ywporY7u).

Echocardiographic assessment of left to right shunts: atrial septal defect, ventricular septal defect, atrioventricular septal defect, patent arterial duct

This review article will guide the reader through the basics of echocardiographic assessment of congenital left to right shunts in both paediatric and adult age groups. After reading this article, the reader will understand the pathology and clinical presentation of atrial septal defects (ASDs), ventricular septal defects (VSDs), atrioventricular septal defects (AVSDs) and patent arterial duct. Echocardiography is the mainstay in diagnosis and follow-up assessment of patients with congenital heart disease. This article will therefore describe the echocardiographic appearances of each lesion, and point the reader towards specific features to look for echocardiographically.

Follow-Up Imaging in Patients with Blunt Splenic or Hepatic Injury Managed Nonoperatively

Nonoperative management of blunt splenic and hepatic injuries has become the standard of care for hemodynamically stable patients. However, nonoperative management may lead to delayed complications and appropriate follow-up is therefore crucial. The aim of this systematic literature review was to assess the role of different imaging modalities in the follow-up assessment of patients with blunt splenic or hepatic injuries using the PubMed database. Eighteen studies were found to be relevant to the topic. A total of 2725 patients were enrolled in the included studies. Both retrospective and prospective studies, but no randomized controlled trials were found. In these studies, CT, ultrasound, and contrast-enhanced ultrasound were discussed. CT was the most commonly used imaging modality. Taking into account all studies included, only one patient underwent intervention due to a complication diagnosed by follow-up CT scan in the absence of clinical signs and symptoms. This equates to a total of 920 CT scans performed to diagnose one clinically nonevident complication that required intervention. Based on the reviewed literature, routine imaging follow-up CT scans may not be indicated in asymptomatic patients with lower grade blunt splenic or hepatic injuries. Contrast-enhanced ultrasound is a promising alternative imaging modality for the follow-up of these patients.
