Risk factors for early and late mortality in hospitalized older patients: the continuing importance of functional status

BACKGROUND: Prognostic information collected at hospital admission may be useful in defining care objectives and in deciding on therapy for older people. The aim of our study was to identify admission risk factors for in-hospital and postdischarge mortality. METHODS: The study included 987 patients aged 70 years and older admitted to the geriatric ward of San Giovanni Battista Hospital in Torino during 1995 and 1996. Demographic, clinical, and functional variables were collected on admission to hospital and examined as potential risk factors for mortality during hospitalization and at 5 years of follow-up. RESULTS: During their hospital stay, 147 patients (14.9%) died. Risk factors independently associated with in-hospital mortality included functional impairment (Activities of Daily Living [ADL]) (OR [odds ratio] 1.73, CI [confidence interval] 95% 1.02-2.95), dependence related to medical conditions (OR 2.18, CI 95% 1.39-3.42), cerebrovascular disease (OR 3.23, CI 95% 1.64-6.37), cancer (OR 4.52, CI 95% 1.99-10.24), albumin 3.0-3.4 g/dl (OR 4.51, CI 95% 2.76-7.35), albumin <3.0 g/dl (OR 6.83, CI 95% 3.59-13.0), creatinine 1.5-3 mg/dl (OR 2.23, CI 95% 1.36-3.65), creatinine >3 mg/dl (OR 2.55, CI 95% 1.10-5.93), and fibrinogen >/=452 mg/dl (OR 1.91, CI 95% 1.26-2.89). During the 5-year follow-up, 553 patients (67.7%) died. Variables independently associated with mortality in multivariate analysis were age 75-84 years (HR [hazard ratio] 1.40, CI 95% 1.10-1.78), >/=85 years (HR 2.08, CI 95% 1.59-2.72), male sex (HR 1.50, CI 95% 1.24-1.81), ADL dependency (HR 1.24, CI 95% 1.01-1.52), >/=5 errors on Short Portable Mental Status Questionnaire (HR 1.34, CI 95% 1.10-1.63), dependence on Dependence Medical Index (HR 1.36, CI 95% 1.10-1.67), presence of cancer (HR 2.58, CI 95% 1.80-3.71), hemoglobin /=2 (HR 1.49, CI 95% 1.14-1.95). CONCLUSIONS: A complete functional and clinical evaluation at hospital admission permits identification of patients at higher risk of early and long-term mortality.     

Application of the “Hybrid Approach” to Chronic Total Occlusion Interventions: A Detailed Procedural Analysis

Objective

To assess the outcomes of the “hybrid” approach to chronic total occlusion (CTO) percutaneous coronary interventions (PCIs).

Background

The “hybrid approach” to CTO PCI advocates appropriate and early change of crossing strategy to maximize success, safety, and efficiency.

Methods

We prospectively recorded and analyzed detailed step‐by‐step procedural data in 73 consecutive CTO PCI cases performed by a single operator between July 2011 and August 2012.

Results

Technical success was achieved in 66 of 73 cases (90.4%). Mean patient age was 65 ± 7 years, and 30% had prior coronary artery bypass surgery. Dual injection was used in 78%. The primary approach was retrograde in 9 cases (12.5%) and antegrade in 64 cases (87.5%), of whom 25 cases (39.1%) underwent retrograde attempt after failed antegrade approach. The initial crossing approach was successful in 40 cases (54.8%), but 32 cases (44%) required 3.6 ± 1.4 approach changes (range 2–7). Antegrade wire escalation, antegrade dissection/reentry, and retrograde crossing were utilized in 97.2%, 46.6%, and 46.6% of cases, respectively. Among successful cases, the final CTO crossing technique was antegrade wire escalation in 50.0%, antegrade dissection/reentry in 24.2%, and retrograde in 25.8%. The mean procedure time, fluoroscopy time, and air kerma radiation exposure until CTO crossing or stopping the procedure were 66 ± 55 minutes, 25 ± 23 minutes, and 2.3 ± 1.9 Gray, respectively. Three patients (4.1%) had a major complication.

Conclusion

In the “hybrid approach” to CTO PCI, changes in crossing strategy were needed in approximately half the cases, resulting in high success and low complication rates. (J Interven Cardiol 2014;27:36–43)

     

Malignant fibrous histiocytoma presenting with complete opacification of the hemithorax: A case report

BACKGROUND

Malignant fibrous histiocytoma, a subtype of primary lung sarcoma is a very rare disease. It usually presents as a lung nodules and the final diagnosis is made by immunohistochemical studies.

METHODS

A 45-year-old patient presented with progressive dyspnea, dry cough and right shoulder pain. Chest X-ray revealed complete opacification of the right hemithorax. Chest computed tomography confirmed the presence of a heterogeneous lesion occupying the whole right hemithorax causing a mass effect on the trachea. Ultrasound guided biopsy was done and final pathology was suggestive of malignant fibrous histiocytoma.

CONCLUSION

Progressive dyspnea in young otherwise healthy patients should be investigated early on. In our case the presence of right shoulder pain indicates advance disease illustrated by the singular imaging findings.     

Anti-L-selectin monoclonal antibody treatment in mice enhances tumor growth by preventing CTL sensitization in peripheral lymph nodes draining the tumor area

To examine the in vivo contribution of L-selectin in the sensitization of tumor-specific CTL, we investigated the effects of treatment with the anti-L-selectin monoclonal antibody (MAb) MEL-14 on the immune response to Moloney-murine sarcoma virus (M-MSV)-induced tumors, which exhibit spontaneous regression following generation of a strong virus-specific CTL response. Daily systemic administration of MEL-14 for 10 days to M-MSV-injected mice gave rise to larger sarcomas that persisted for a longer time, compared with those arising in control mice injected with virus only. The enhanced tumor growth could not be attributed to cytotoxic activity on leukocytes by MEL-14 since no reduction in the total cell number was detected in peripheral blood and spleen of MAb-treated mice. Evaluation of the immunological response in MAb-treated animals revealed a strong reduction in the generation of virus-specific CTL precursors (CTLp) in tumor-draining peripheral lymph nodes (PLN) 10 and 15 days after M-MSV injection, while in spleen, where lymphocyte localization is independent of L-selectin expression, CTLp generation was only delayed. By day 20, when tumors had begun to regress, the CTLp number showed a marked increase in both spleen and local PLN, where naive recirculating CTL could now enter because L-selectin was no longer down-regulated or blocked by the injected MAb. Our findings indicate that functional inactivation of L-selectin by MEL-14 treatment prevented migration of naive L-selectin ⁺ CTL through high endothelial venules (HEV) and their accumulation in PLN draining the tumor area, thereby precluding the initiation of a tumor-specific CTL response that takes place primarily at this site. © 1996 Wiley-Liss, Inc.     

Lack of Amphetamine-Like Effects After Administration of Mefenorex in Normal Young Subjects

Mefenorex is an indirect sympathomimetic amine which acts as an anorectic drug and is used in combination with low diet to treat excess weight. The central nervous system (CNS) effects of mefenorex were assessed in a randomized, double-blind, three-way cross-over, placebo-controlled study involving nine healthy young male volunteers. They received either a single oral dose of mefenorex 80 mg (twice the recommended dose) or d-amphetamine sulfate 18 mg or a placebo at 1-week intervals. CNS pharmacodynamic measurements consisted of subjective evaluation (visual analogue scales and the Addiction Research Centre inventory (ARCI)), EEG, psychomotor performance and attention (tracking, simple and choice reaction times, tapping, continuous performance task, DSST, body sway) and memory (working memory and recall of a word list). d-Amphetamine produced a typical psychostimulant EEG profile (significant decrease in slow delta waves and increase in fast beta activities), significantly increased amphetamine, benzedrine and morphine–benzedrine scores of ARCI and significantly decreased body sway compared to placebo and mefenorex. A trend in favour of a stimulant effect occurred for all other parameters (particularly speed of reaction) and no changes of memory were noticed. In contrast, mefenorex did not produce an amphetamine-like EEG profile, neither significantly changed ARCI scores nor significantly modified psychomotor and memory performance compared to the placebo, although it induced a decrease in body sway. In conclusion, the present results indicate that a single oral dose of mefenorex, at twice the recommended daily dose, does not possess amphetamine-like subjective and EEG stimulant effects or sensations of well-being, often encountered with drugs of abuse liability potential, in a healthy young population.     

Long-term outcomes after ascending aortic replacement and aortic root replacement for type A aortic dissection

 Open in a separate windowOBJECTIVESWe investigated whether the selective use of supracoronary ascending aorta replacement achieves late outcomes comparable to those of aortic root replacement for acute Stanford type A aortic dissection (TAAD).METHODSPatients who underwent surgery for acute type A aortic dissection from 2005 to 2018 at the Helsinki University Hospital, Finland, were included in this analysis. Late mortality was evaluated with the Kaplan–Meier method and proximal aortic reoperation, i.e. operation on the aortic root or aortic valve, with the competing risk method.RESULTSOut of 309 patients, 216 underwent supracoronary ascending aortic replacement and 93 had aortic root replacement. At 10 years, mortality was 33.8% after aortic root replacement and 35.2% after ascending aortic replacement (P = 0.806, adjusted hazard ratio 1.25, 95% confidence interval, 0.77–2.02), and the cumulative incidence of proximal aortic reoperation was 6.0% in the aortic root replacement group and 6.2% in the ascending aortic replacement group (P = 0.65; adjusted subdistributional hazard ratio 0.53, 95% confidence interval 0.15–1.89). Among 71 propensity score matched pairs, 10-year survival was 34.4% after aortic root replacement and 36.2% after ascending aortic replacement surgery (P = 0.70). Cumulative incidence of proximal aortic reoperation was 7.0% after aortic root replacement and 13.0% after ascending aortic replacement surgery (P = 0.22). Among 102 patients with complete imaging data [mean follow-up, 4.7 (3.2) years], the estimated growth rate of the aortic root diameter was 0.22 mm/year, that of its area 7.19 mm²/year and that of its perimeter 0.43 mm/year.CONCLUSIONSWhen stringent selection criteria were used to determine the extent of proximal aortic reconstruction, aortic root replacement and ascending aortic replacement for type A aortic dissection achieved comparable clinical outcomes.     

Efficacy of fleece-bound sealing system (TachoSil®) in delayed anterior tracheal lacerations secondary to ischemic tracheal necrosis after total thyroidectomy

Thyroidectomy is one of the commonest surgical operations performed in endocrine surgery; results are generally excellent and morbidity and mortality usually are negligible. Total thyroidectomy's complication rates are low, with an overall incidence of 4.3% among experienced surgeons: the most frequent complications are vocal cord paresis or paralysis, hypoparathyroidism, hypocalcemia, haematoma and wound infection. Tracheal injury following thyroidectomy is even more rare. As reported from some authors, inadvertent tracheal injury has an incidence of 0-0.6% during thyroidectomy. Tracheal laceration (generally located in the posterolateral surface) is often recognized and repaired immediately, during the same intervention. Rarely, following a total thyroidectomy, a delayed tracheal rupture may occur secondary to an ischemic damage of the trachea. This has been described in few cases reported in literature. In this paper we report of a case in which delayed tracheal lacerations appeared 10 days after the patient underwent total thyroidectomy: a prompt surgical operation was efficient using both direct sutures of tracheal breaches and a patch of fibrinogen-thrombin coated collagen fleece covering the entire surface.
