Realizability Of The Morse Polytope

In this article we will show that, in general, for each integral point (γ0,..., γn) in the Morse polytope, Pκ(h0,..., hn), one can associate an abstract Lyapunov graph L(h0,..., hn, κ) with ntd-labelling and realize a corresponding flow on Mn, where the Betti numbers of Mn satisfy βj (Mn) = βn-j(Mn) = γj, for all 0 < j ≤ ⌊n/2⌋.615986Baez, J.C., The Octonions (2002) Bull.

Evaluation Of The Nnecdsg Score In A Brazilian Public Hospital [avaliação Do Escore Nnecdsg Em Um Hospital Público Brasileiro]

Objective: To compare the observed incidence of mediastinitis and strokes versus the expected incidence according to the NNECDSG score (Northern New England Cardiovascular Disease Study Group) in a population submitted to coronary artery bypass graft surgery. Methods: A retrospective consultation was made of medical records of all patients submitted to isolated CABG from January 1st, 2000 to December 31st, 2004, at the Cardiac Surgery Service of the Triângulo Mineiro Federal University (UFTM). Data regarding the incidences of observed mediastinitis and strokes and those estimated by the NNECDSG score were submitted to the Kolmogorov-Smirnov normality test. A comparison was achieved using the paired Student t test, with the level of significance determined as p=0.05. Results: A group of 230 patients were analyzed, including 144 (62.60%) men and 86 (37.39%) women. Sixty-one (26.52%) presented with diabetes, 30 (13.04%) with chronic obstructive pulmonary disease (COPD) and 23 (10%) had peripheral vascular disease (PVD). Emergency surgery occurred in 34 (14.78 %) cases. In 37 (16.08%) patients an ejection fraction (EF) of less than 40% was identified. Mediastinitis occurred in 12 (5.21%) patients and despite the greater general incidence in the sample studied, no statistical significance was found. Strokes occurred in 12 patients (5.21%) and in spite of the higher mean percentage incidence of observed strokes for all scores, a level of statistical significance was not found. Conclusions: Although the incidences of mediastinitis and strokes were greater in the population studied, these values showed no statistical significance, confirming the score recommended by the NNECDSG as a safe and efficient method for predicting postoperative mediastinitis and strokes in patients submitted to coronary artery bypass grafting surgery in the UFTM.222212217Roques, F., Nashef, S.A., Michel, P., Gauducheau, E., de Vincentiis, C., Baudet, E., Risk factors and outcome in European cardiac surgery: Analysis of the EuroSCORE multinational database of 19030 patients (1999) Eur J Cardiothorac Surg, 15 (6), pp. 816-822Feier, F.H., Sant'anna, R.T., Garcia, E., De Bacco, F.W., Pereira, E., Santos, M.F., Modificações no perfil do paciente submetido à operação de revascularização do miocárdio.

Dental anomalies as part of the cleft spectrum

Objective: The aim of this Study was to determine subphenotypes of clefts based on tooth development. Dental phenotypes (tooth agenesis, supernumerary and impacted teeth, transposition, and structural anomalies) outside the cleft area in the permanent dentition of oral cleft individuals were investigated. Design: Evaluation of dental records of cleft patients. Setting: National Museum of Health and Medicine, Washington, D.C. Patients, Participants: A collection of dental casts, radiographic and clinical records of 146 patients with oral clefts was evaluated. Main Outcome Measure: Association of dental anomalies with preferential subtypes of clefts. Results: Forty-seven individuals (32.19%) presented at least one dental anomaly outside the cleft area. Individuals with complete cleft lip and palate (CLP) presented more dental anomalies than individuals with incomplete CLP (p = .04). Cleft palate individuals presented more dental anomalies than CLP individuals (p = .048). Maxillary lateral incisors and premolars were the most affected teeth. High incidence of maxillary second premolar agenesis was observed in individuals with bilateral CLP (p = .04). In cases with unilateral CLP, 12.5% presented dental anomalies of the maxillary lateral incisors on the noncleft side. Cleft palate individuals presented a high incidence of mandibular premolar anomalies (p= .004). Conclusion: Future studies should consider the inclusion of a complete dental description to aid in the definition of cleft subphenotypes to be studied
