A one-year longitudinal study on suicidal ideation, depression and anxiety during the COVID-19 pandemic.

This longitudinal study aimed to examine the within-person changes in suicidal ideation, depression, and anxiety between the first wave of COVID-19 pandemic and the third wave (i.e., one year later), while nationwide lockdowns were in effect. Among 720 respondents, 4.72% presented suicidal ideation, which appeared unaltered one-year post-pandemic onset, while both depression (21.25% versus 28.06%) and anxiety (12.08% versus 18.47%) increased significantly, adjusting for gender, age, and mental health history. Suicidal ideation, depression, and anxiety during the third pandemic wave were independently associated with crucial socio-demographic, clinical, psychological and psychopathological variables, in the stepwise regression analyses performed.

Effects of interval cycle training with or without strength training on vascular reactivity in heart failure patients.

BACKGROUND: Exercise training confers beneficial effects on vascular reactivity in patients with chronic heart failure (CHF). This randomized study compares the effects of interval cycle training combined with strength training versus interval training alone on vascular reactivity in CHF patients. METHODS: Twenty-eight consecutive stable CHF patients (23 males, 53 ± 10 years, 28.4 ± 4.1 kg/m(2), left ventricular ejection fraction of 37 ± 12%) were randomly assigned to 3 times' weekly training sessions for 3 months, consisting of a) 40 minutes of interval cycle training (n = 14), versus b) 20 minutes of similar interval training plus 20 minutes of strength training of the quadriceps, hamstrings, muscles of the shoulder and biceps brachialis (n = 14). The work/recovery ratio of each session was 30/60 seconds. The intensity of interval training was set at 50% of the peak workload achieved at the steep ramp test (consisted of a 25-Watt increase on a cycle ergometer every 10 seconds until exhaustion). All patients underwent maximal, symptom-limited cardiopulmonary exercise testing and ultrasound evaluation of vascular reactivity by flow-mediated vasodilation (FMD) before and after the program. RESULTS: A significant improvement in FMD was observed in the combined training group (P = 0.002), in contrast to the interval training alone group (P = NS); the improvement was significantly greater in the combined training than in the interval training alone group (P < .05). Peak oxygen uptake increased significantly and similarly in both groups, in the interval training group (P = .03), and in the combined training group (P = .006). No significant correlation was found between FMD improvement and cardiopulmonary exercise parameters. CONCLUSIONS: A combined high-intensity, interval cycle exercise with strength training induces a greater beneficial effect on vascular reactivity rather than interval exercise training alone in CHF patients.

Evaluation of Indirect Methods for Motion Compensation in 2-D Focal Liver Lesion Contrast-Enhanced Ultrasound (CEUS) Imaging.

This study investigates the application and evaluation of existing indirect methods, namely point-based registration techniques, for the estimation and compensation of observed motion included in the 2-D image plane of contrast-enhanced ultrasound (CEUS) cine-loops recorded for the characterization and diagnosis of focal liver lesions (FLLs). The value of applying motion compensation in the challenging modality of CEUS is to assist in the quantification of the perfusion dynamics of an FLL in relation to its parenchyma, allowing for a potentially accurate diagnostic suggestion. Towards this end, this study also proposes a novel quantitative multi-level framework for evaluating the quantification of FLLs, which to the best of our knowledge remains undefined, notwithstanding many relevant studies. Following quantitative evaluation of 19 indirect algorithms and configurations, while also considering the requirement for computational efficiency, our results suggest that the "compact and real-time descriptor" (CARD) is the optimal indirect motion compensation method in CEUS.

Optic nerve sonography in the diagnostic evaluation of adult brain injury.

INTRODUCTION: The optic nerve sheath diameter (ONSD) may be increased in brain-injured patients, especially children, with intracranial hypertension. We investigated whether measurements of ONSD correlated with simultaneous noninvasive and invasive measurements of the intracranial pressure (ICP) in brain-injured adults. METHODS: Seventy-six critical care patients (58 males; 47 +/- 18 years old) were included in the study. Fifty patients suffered from brain injury, whereas 26 had no intracranial pathology and served as control individuals. Initially, brain-injured patients were evaluated clinically (Glasgow Coma Scale) and using a semiquantitative (I to VI) neuroimaging scale (Marshall Scale). Thereafter, the patients were divided into those with moderate (Marshall Scale = I and Glasgow Coma Scale > 8 [n = 18]) and severe (Marshall Scale = II to VI and Glasgow Coma Scale < or =8 [n = 32]) brain injury. All patients underwent noninvasive measurement of the ICP (estimated ICP) by transcranial Doppler sonography, and synchronous ONSD measurements by optic nerve sonography. Finally, invasive ICP measurement using an intraparenchymal catheter was performed in patients with severe brain injury. RESULTS: ONSD and estimated ICP were both significantly increased (6.1 +/- 0.7 mm and 26.2 +/- 8.7 mmHg, respectively; P < 0.0001) in patients with severe brain injury as compared with patients with moderate brain injury (4.2 +/- 1.2 mm and 12.0 +/- 3.6 mmHg) and compared with control individuals (3.6 +/- 0.6 mm and 10.3 +/- 3.1 mmHg). Furthermore, in patients with severe brain injury the ONSD measurements were strongly correlated with estimated ICP values (r = 0.80, P < 0.0001) as well as with the neuroimaging scale results (r = 0.82, P < 0.001). In the patients with severe brain injury, ONSD measurements correlated with invasive ICP values (r = 0.68, P = 0.002). The best cut-off value of ONSD for predicting elevated ICP was 5.7 mm (sensitivity = 74.1% and specificity = 100%). CONCLUSION: ONSD measurements correlate with noninvasive and invasive measurements of the ICP, and with head computed tomography scan findings in brain-injured adults. Hence, optic nerve sonography may serve as an additional diagnostic tool that could alert clinicians to the presence of elevated ICP, whenever invasive ICP evaluation is contraindicated and/or is not available. This trial is International Standard Randomised Controlled Trial Number registered (ISRCTN 91941687).

Transcatheter chemoembolization in the treatment of HCC in patients not eligible for curative treatments: midterm results of doxorubicin-loaded DC bead.

PURPOSE: To examine the results of segmental transcatheter arterial chemoembolization with doxorubicin-loaded DC Bead in the treatment of hepatocellular carcinoma (HCC) in non-surgical candidates. MATERIAL AND METHODS: Seventy-one patients (60% men; 11% women; mean age 63; range 46-71 years) with documented HCC of 3-10 cm in diameter (mean 6.2) were enrolled prospectively in the study. All patients had cirrhosis-related HCC that was developed on an underlying controlled hepatitis infection. Only patients with compensated cirrhosis--Child A or B--were included in this study. RESULTS: Overall complete response (CR) according to EASL on an intention to treat basis was seen in 11 patients who developed complete necrosis (15.5%). Objective response (OR) ranged from 66.2% to 85.5% across the four treatments. Survival at 12 months was 97.05%. Sustained CR was observed in 11 (16.1%), and OR in 49 (72%). Sustained partial response was seen in 49 patients (72.05%). Survival at 18 months was 94.1%. At 24 months follow-up survival was 91.1%. Sustained OR was seen in 45 patients (66.2%) while sustained CR was 16.1% (11/68). At 30 months survival was 88.2%. One patient with CR developed multifocal HCC in areas that most likely were not embolized during the previous embolization sessions. In this patient recurrence-free survival was 28 months. Alpha Fetroprotein levels decreased significantly in measurements 1 month post each procedure (p < 0.001). Bilirubin, gamma-GT, aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase (ALP) showed only transient increases observed during the study period. Severe procedure-related complications were seen in 4.2% (cholecystitis: n = 1; liver abscess: n = 1; pleural effusion: n = 1). Post Embolization Syndrome (PES) was observed in all patients. CONCLUSION: Transcatheter arterial chemoembolization with DC Bead is an effective and safe procedure in the treatment of HCC patients not eligible for curative treatments with high rates of response and high rates of mid term survival.

Automatic Identification of the Optimal Reference Frame for Segmentation and Quantification of Focal Liver Lesions in Contrast-Enhanced Ultrasound.

Post-examination interpretation of contrast-enhanced ultrasound (CEUS) cineloops of focal liver lesions (FLLs) requires offline manual assessment by experienced radiologists, which is time-consuming and generates subjective results. Such assessment usually starts by manually identifying a reference frame, where FLL and healthy parenchyma are well-distinguished. This study proposes an automatic computational method to objectively identify the optimal reference frame for distinguishing and hence delineating an FLL, by statistically analyzing the temporal intensity variation across the spatially discretized ultrasonographic image. Level of confidence and clinical value of the proposed method were quantitatively evaluated on retrospective multi-institutional data (n = 64) and compared with expert interpretations. Results support the proposed method for facilitating easier, quicker and reproducible assessment of FLLs, further increasing the radiologists' confidence in diagnostic decisions. Finally, our method yields a useful training tool for radiologists, widening CEUS use in non-specialist centers, potentially leading to reduced turnaround times and lower patient anxiety and healthcare costs.

Sonographic lobe localization of alveolar-interstitial syndrome in the critically ill.

Introduction. Fast and accurate diagnosis of alveolar-interstitial syndrome is of major importance in the critically ill. We evaluated the utility of lung ultrasound (US) in detecting and localizing alveolar-interstitial syndrome in respective pulmonary lobes as compared to computed tomography scans (CT). Methods. One hundred and seven critically ill patients participated in the study. The presence of diffuse comet-tail artifacts was considered a sign of alveolar-interstitial syndrome. We designated lobar reflections along intercostal spaces and surface lines by means of sonoanatomy in an effort to accurately localize lung pathology. Each sonographic finding was thereafter grouped into the respective lobe. Results. From 107 patients, 77 were finally included in the analysis (42 males with mean age = 61 ± 17 years, APACHE II score = 17.6 ± 6.4, and lung injury score = 1.0 ± 0.7). US exhibited high sensitivity and specificity values (ranging from over 80% for the lower lung fields up to over 90% for the upper lung fields) and considerable consistency in the diagnosis and localization of alveolar-interstitial syndrome. Conclusions. US is a reliable, bedside method for accurate detection and localization of alveolar-interstitial syndrome in the critically ill.

Intermediate and advanced hepatocellular carcinoma treated with the antiangiogenic agent sorafenib. Evaluation with unenhanced and contrast-enhanced ultrasonography.

AIMS: To evaluate the sonographic changes observed in hepatocellular carcinoma (HCC) post antiangiogenic treatment with sorafenib. PATIENTS AND METHODS: Twenty one intermediate or advanced HCC patients (19 men, 2 women; mean age: 66.8 years; 32 target tumors-TTs) received sorafenib as monotherapy and were studied with unenhanced ultrasonography (US) and contrast-enhanced ultrasonography (CEUS) with a second generation echo-enhancer (SonoVue) at bimonthly intervals. Changes in lesional size, echotexture and enhancement were evaluated. Response was classified according to RECIST (Response Evaluation Criteria In Solid Tumors) and modified (m) RECIST. RESULTS: Cystic changes were detected on US in 4 patients (7 lesions); CEUS showed a significant (51-100%) decrease of viable, enhancing TTs in the aforementioned patients. Four additional patients (5 lesions) showed a 73-87% decrease of their viable TTs on CEUS, but no changes on US. 13/21 patients showed less than 30% decrease, no change, or increase of their viable TTs. Based on the last sonographic evaluation, response was as follows: RECIST- Complete Response, CR (n=0), Partial Response, PR (n=1), Stable Disease, SD (n=16), Progressive Disease, PD (n=4); mRECIST- CR (n=2), PR (n=6), SD (n=11), PD (n=2). The 8 responders (CR+PR) according to mRECIST had significantly longer mean overall survival (OS) compared to the 13 non-responders (21.5 vs 12.2 months, p=0.018, Kaplan-Meier method). However, statistical significance was reduced (p=0.065) after adjustment for BCLC and Child's class. CONCLUSION: US may occasionally detect changes indicative of the effect of sorafenib on HCC, but CEUS is required to evaluate and grade post-therapeutic reduction of tumoral enhancement. The latter is likely to correlate with OS.
