Early Results of Endovascular Treatment of the Thoracic Aorta Using the Valiant Endograft

Endovascular repair of the thoracic aorta has been adopted as the first-line therapy for much pathology. Initial results from the early-generation endografts have highlighted the potential of this technique. Newer-generation endografts have now been introduced into clinical practice and careful assessment of their performance should be mandatory. This study describes the initial experience with the Valiant endograft and makes comparisons with similar series documenting previous-generation endografts. Data were retrospectively collected on 180 patients treated with the Valiant endograft at seven European centers between March 2005 and October 2006. The patient cohort consisted of 66 patients with thoracic aneurysms, 22 with thoracoabdominal aneurysms, 19 with an acute aortic syndrome, 52 with aneurysmal degeneration of a chronic dissection, and 21 patients with traumatic aortic transection. The overall 30-day mortality for the series was 7.2%, with a stroke rate of 3.8% and a paraplegia rate of 3.3%. Subgroup analysis demonstrated that mortality differed significantly between different indications; thoracic aneurysms (6.1%), thoracoabdominal aneurysms (27.3%), acute aortic syndrome (10.5%), chronic dissections (1.9%), and acute transections (0%). Adjunctive surgical procedures were required in 63 patients, and 51% of patients had grafts deployed proximal to the left subclavian artery. Comparison with a series of earlier-generation grafts demonstrated a significant increase in complexity of procedure as assessed by graft implantation site, number of grafts and patient comorbidity. The data demonstrate acceptable results for a new-generation endograft in series of patients with diverse thoracic aortic pathology. Comparison of clinical outcomes between different endografts poses considerable challenges due to differing case complexity.     

Bail-out intracranial stenting with Solitaire AB device after unsuccessful thrombectomy in acute ischemic stroke of anterior circulation

Background

Recent trials established the efficacy of mechanical stent-retriever thrombectomy for treatment of stroke patients with large vessel occlusion (LVO) in the anterior circulation. However, stent-retriever thrombectomy may not accomplish successful recanalization in all patients. The aim of this study is to report the role of bail-out permanent stenting after failure of mechanical thrombectomy.

Anxiety,depression, and quality of life in Parkinson’s disease: the implications of multidisciplinary treatment

Anxiety and depression in Parkinson’s disease (PD) reduce well-being of the patients. Emotional alterations influence motor skills and cognitive performance; moreover, they contribute significantly and independently to worsen rehabilitative treatment response. We investigated anxiety, depression, and quality of life in PD patients subjected to multidisciplinary rehabilitative training. The self-controlled study included 100 PD patients (49 males and 51 females with the mean age of 64.66 years) admitted to 60 days hospitalization rehabilitative program, between January 2017 and December 2018. Motor, cognitive, linguistic abilities, and functional independence were evaluated at admission (T0 baseline visit) and 60 days after (T1) the multidisciplinary rehabilitation including motor exercises, speech therapies, and cognitive intervention. The multidisciplinary rehabilitation improved functional status in PD patients and exerted its positive effects on mood, motor abilities, autonomy in the activities of daily life, perception of quality of life, cognitive performance and speech skills. Non-motor symptoms may worsen severe disability and reduce quality of life. They are often poorly recognized and inadequately treated. Nonetheless, multidisciplinary rehabilitative training represents an optimal strategy to improve disease management. The study was approved by Istituito di Ricovero e Cura a Carattere Scientifico (IRCCS) Centro Neurolesi “Bonino-Pulejo” Ethical Committee (approval No. 6/2016) in June 2016.

Changes in biological markers after primary chemotherapy for breast cancers

The profiles of functional (proliferative rate and cell distribution in the cell cycle) and phenotypic (nuclear DNA content and hormone receptor status) biological markers and the expression of P53 and Bcl-2 proteins were prospectively evaluated in breast cancers before and after different regimens of primary chemotherapy. Overall, changes induced on the 2 proliferation indices (³H-thymidine labelling index, ³H-dT LI, and flow-cytometric S-phase fraction, FCM-S) mainly consisted of a decrease for rapidly proliferating tumours and an increase or no change for slowly proliferating tumours. However, when considered as a function of treatment type, changes of ³H-dT LI and FCM-S were superimposable in rapidly proliferating tumours, regardless of the type of treatment, and in slowly proliferating tumours only after anthracycline-including regimens. Conversely, following CMF, FCM-S was increased in 90% of the cases and ³H-dT LI in only 50%. Our data imply that the 2 proliferation indices could reflect different phenomena: an actual variation of proliferative activity by ³H-dT LI and an accumulation of cells in the S-phase by FCM-S. In addition, a higher accumulation of cells in G₂-M phases could be detected by FCM after anthracycline-including regimens than after CMF. The fraction of P53-positive cells was reduced by primary chemotherapy in about 50% of P53-positive tumours, whereas Bcl-2 expression was only marginally affected. DNA ploidy and hormone receptor status did not change in about 75% of cases, regardless of the chemotherapeutic regimen. © 1995 Wiley-Liss, Inc.     

Insulin resistance and glomerular hemodynamics in essential hypertension

BACKGROUND: Arterial hypertension is an important cause of end-stage renal failure. Insulin has been shown to modify glomerular hemodynamics in hypertensive subjects. The aim of this work, therefore, was to observe the relationships between renal hemodynamics and insulin resistance in arterial hypertension. METHODS: Sixty-two non-diabetic hypertensive patients and 25 healthy normal subjects were studied. Renal plasma flow and the glomerular filtration fraction were determined by renoscintigraphy and the insulin sensitivity by an oral glucose test. RESULTS: Renal plasma flow in hypertensive subjects was lower than expected and was related to pressure values, whereas the mean glomerular filtration rates were not different in the two groups. In most patients the filtration fraction was higher than expected. A lower glomerular filtration rate and lower filtration fraction were found in patients with higher insulin resistance. CONCLUSIONS: The progressive decrease of glomerular function in subjects with hypertension is linked with insulin-resistance.     

Evaluation of novel compounds interacting with H2-histamine receptors: Effect on histamine-sensitive adenylate cyclase activity in guinea-pig gastric mucosa

The activity of a number of compounds belonging to the novel class ofN-imidazolylphenyl-N'-alkyl-formamidines on histamine-sensitive adenylate cyclase was evaluated. All substances inhibited histamine-dependent adenylate cyclase activation. The compounds which were investigated in a wider concentration range, i.e. DA 4360, DA 4577, and DA 4626, behaved as simple competitive antagonists, yielding apparentK _B values comparable with those estimated in conventional H₂-receptor assays. These results provide further evidence for the highly selective H₂-receptor antagonism of these new molecules, and confirm the suitability of the histamine-stimulated adenylate cyclase assay in guinea-pig gastric cells as a functionally reduced system for the study of H₂ antagonists.     

Follow-up of abnormal or inadequate cervical smears using two guidance systems: RCT on effectiveness

BACKGROUND: To improve follow-up compliance after an initial inadequate or abnormal cervical smear, two follow-up guidance systems were tested for effectiveness. A comprehensive system (cytopathology laboratory monitored the follow-up of all abnormal and inadequate smears) was compared to a selective system (monitoring was left to the smear taker; laboratory acted as a safety net). METHODS: In an RCT on all family practices (N = 171) in the catchment areas of two cytopathology laboratories (Nijmegen region, The Netherlands, 1998-2000), practices were allocated at random to one of the follow-up guidance systems. All women included were registered at the practices, invited to the national screening program and had abnormal or inadequate smears. Measurements comprised of (1) follow-up compliance at baseline and 1 year after the initial smear and (2) diagnostic outcome of the follow-up smear. RESULTS: During the study period, 132 practices sent their cervical smears to the laboratories. The comprehensive system covered 1226 women, the selective 1034. In the comprehensive system, the increase in follow-up compliance for initial inadequate and slightly abnormal smears was significantly higher (8.9%) than in the selective one, which implied an extra detection of eleven, more serious, abnormalities per 1000 women. CONCLUSION: The comprehensive system was more effective than the selective and is suitable for use on a larger scale.     

Programmed cell death of myelin basic protein-specific T lymphocytes is reduced in patients with acute multiple sclerosis

We investigated the apoptosis of myelin basic protein (MBP)-specific T lymphocytes in multiple sclerosis (MS) patients with acute (AMS) or stable (SMS) MS by evaluating the expression of apoptosis markers on peripheral cells. Cells of healthy controls (HC) were evaluated as well. Results showed that mitogen-stimulated apoptosis was comparable among patients and controls, whereas MBP-stimulated CD4+ and CD8+ 7-AAD+ and 7-AAD+ Fas+ cell (apoptotic cells) were significantly reduced in AMS patients. A reduction of the apoptotic rate of myelin-specific CD4+ and CD8+ T lymphocytes could be involved in the immune-mediated destruction of the myelin sheath seen in AMS patients.
