Characteristics of patients and predictors of in‐hospital mortality after hospitalization for head and neck cancers
Authors: Allareddy Veerasathpurush , Konety Badrinath R. 
Published: April 2006

AbstractBACKGROUNDThe objectives of this study were to describe the characteristics of patients who were hospitalized for head and neck cancer (HNC) during the years 2000 through 2003 and to identify predictors of in‐hospital mortality.METHODSThe Nationwide Inpatient Sample for the years 2000 through 2003 was used. All patients who had a primary diagnosis of any of the HNCs were included in the study. Univariate and multivariate logistic regression analyses were used to identify patient and hospital characteristics that were associated with in‐hospital mortality.RESULTSIn total, 24,803 patients were hospitalized for HNCs. The average age of patients was 62 years, the mean length of stay in the hospital was 7.89 days, and the in‐hospital mortality rate was 5.18%. Patients who had comorbid conditions and complications and patients who were grouped under the self‐pay/no charge/others category had greater odds of in‐hospital mortality compared with patients who were covered by private insurance (P<.02). Patients who were treated in large‐bed, urban, or teaching hospitals had lower odds of in‐hospital mortality compared with patients who were treated in small or medium‐bed, rural, or nonteaching hospitals, respectively(P<.03).CONCLUSIONSPatients with comorbid conditions and complications and patients without adequate insurance coverage had greater odds of in‐hospital mortality. One reason for this may be inadequate access to care because of the absence of insurance or underinsurance. Further studies controlling for disease stage will be required to determine whether insurance status and patient‐related factors can influence outcomes from HNC in individual patients independent of their disease stage.

AbstractThe new tetrathiacrown ethers maleonitrile‐tetrathia‐12‐crown‐4 (mn12S4) and maleonitrile‐tetrathia‐13‐crown‐4 (mn13S4) have been prepared and characterised by X‐ray crystallographic analysis. These crown ethers form 2:1, 3:2 and 1:1 complexes with AgY (Y = BF4, PF6). The crystal structures of [Ag(mn12S4)2]BF4 (3a), [Ag(mn13S4)2]BF4 (4a) and [Ag2(mn13S4)3](PF6)2 (6b) have been determined. Compound 3a contains the centrosymmetric sandwich complex cation [Ag(mn12S4)2]+ where each mn12S4 ligand is coordinated to the Ag centre in an endo manner through all four S atoms. The 2:1 complex [Ag(mn12S4)2]+ is the first sandwich complex with a tetrathiacrown ether and the first complex with an octa(thioether) coordination sphere. The crystal structure of compound 4a also reveals a 2:1 complex. This complex, [Ag(mn13S4)2]+, exhibits a half‐sandwich structure. One mn13S4 ligand coordinates to Ag+ by all four S donor atoms and the other 13S4 crown by only one S atom. Compound 6b contains a dinuclear Ag complex. The Ag complexes 3a,b–8a,b were also studied by electrospray ionisation mass spectrometry. Collision‐induced dissociation (CID) was used to compare the relative stability of 2:1 complexes [AgL2]+ and 1:1 complexes [AgL]+ (L = mn12S4, mn13S4). The 13C NMR chemical shifts of 2:1 and 1:1 Ag complexes and their corresponding free ligands were also estimated and compared. The free energy of the barrier of ring inversion (ΔG‡) for [Ag(mn12S4)2]+ was determined to be 64 kJ mol–1. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
Kinetics of (Porphyrin)manganese(III)‐Catalyzed Olefin Epoxidation with a Soluble Iodosylbenzene Derivative

Published: April 2006

AbstractWe examined the kinetics of a well‐behaved system for homogeneous porphyrin‐catalyzed olefin epoxidation with a soluble iodosylbenzene derivative 1 as the terminal oxidant and Mn(TPFPP)Cl (2) as the catalyst. The epoxidation rates were measured by using the initial rate method, and the epoxidation products were determined by gas chromatography. The epoxidation rate was found to be first order with respect to the porphyrin catalyst and zero order on the terminal oxidant. In addition, we found the rate law to be sensitive to the nature and concentration of olefin substrates. Saturation kinetics were observed with all olefin substrates at high olefin concentrations, and the kinetic data are consistent with a Michaelis–Menten kinetic model. According to the observed saturation kinetic results, we propose that there is a complexation between the active oxidant and the substrate, and the rate‐determining step is thought to be the breakdown of this putative substrate–oxidant complex that generates the epoxidation products and the resting state porphyrin catalyst. Competitive epoxidations further indicate a reversible complexation of the active oxidant and the olefin substrate. The activation parameters ΔH‡ and ΔS‡ for the oxygen‐transfer process (k2) in the cis‐cyclooctene epoxidation were determined to be 12.3 ± 0.9 kcal mol–1 and–15.6 ± 3.2 cal mol–1 K–1, respectively. In addition, the Hammett constant ρ+ was measured for the epoxidation of para‐substituted styrenes, and the value of –0.27 ± 0.04 is too low to be consistent with the involvement of a discrete carbocation in the transition state. We also prepared a (porphyrin)manganese catalyst immobilized on silica support, and found the epoxidation of cis‐cyclooctene catalyzed by this heterogeneous catalyst proceeds at virtually the same turnover frequency as by the homogeneous porphyrin catalyst.

Published: April 2006

AbstractProteins “work together” by actually binding to form multicomponent complexes that carry out specific functions. Proteomic analyses based on the mass spectrum are now key methods to determine the components in protein complexes. The protein–protein interaction or functional association may be known to exist among the extracted protein spots while analyzing the proteins on the 2D gel. In this study, we develop an agent‐based system, namely AgentMultiProtIdent, which integrated two protein identification tools and a variety of databases storing relations among proteins and used to discover protein–protein interactions and protein functional associations, and identify protein complexes and proteins with multiple peptide mass fingerprints as input. The system takes Multiple Peptide Mass Fingerprints (PMFs) as a whole in the protein complex or protein identification. With the relations among proteins, it may greatly improve the accuracy of identification of protein complexes. Also, possible relationship of the multiple peptide mass fingerprints, such as ontology relation, can be discovered by our system, especially in the identification of protein complexes. The agent‐based system is now available on the Web at http://dbms104.csie.ncu.edu.tw/∼protein/NEW2/. © 2006 Wiley Periodicals, Inc. J Comput Chem 27: 1020–1032, 2006
Electroluminescent copolymers based on dihexylfluorene and 2‐{2,6‐bis[2‐(4‐diphenylaminophenyl)vinyl]pyran‐4‐ylidene}malononitrile units

Published: April 2006

AbstractA series of statistical copolymers (poly[(9,9‐di‐n‐hexylfluorene)‐co‐2‐{2,6‐bis‐[2‐(4‐diphenylaminophenyl)vinyl]pyran‐4‐ylidene}malononitrile) were synthesized by the Suzuki coupling reaction. The copolymers showed absorption bands at 379 and 483–489 nm, which were attributed to the oligofluorene segments and the segments containing 2‐[2,6‐bis(2‐{4‐[(4‐bromophenyl)phenylamino]phenyl}vinyl)pyran‐4‐ylidene]malononitrile (3), respectively. The absorption band around 483–489 nm increased with the feed ratio of 3. The photoluminescence (PL) spectra of the copolymers showed emission bands at 420 and 573–620 nm. As the feed ratio of 3 increased, the PL emission in the longer wavelength region redshifted, and the intensity increased as well. The electroluminescence (EL) spectrum of the copolymers showed a very weak emission at 420 nm. The PL and EL emission colors redshifted dramatically with the increase in the feed ratio of 3. The highest occupied molecular orbital and lowest unoccupied molecular orbital levels of the model compound (2‐{2,6‐bis[2‐(4‐diphenylaminophenyl)vinyl]pyran‐4‐ylidene}malononitrile) were determined to be −5.34 and −3.14 eV, respectively. It was concluded that energy transfer took place from the oligofluorene blocks to the segments containing 3 and that direct charge trapping occurred in the segments containing 3 during the EL operation. The Commission Internationale de l'Eclairage (CIE) chromaticity coordinates of the copolymer (x = 0.63, y = 0.37) containing 10 mol % 3 were very close to those (x = 0.67, y = 0.33) for National Television System Committee (NTSC) red with a maximum photometric power efficiency of 0.27 cd/A. © 2006 Wiley Periodicals, Inc.

In it Bellamy transports his young protagonist, Julian West, from the Boston of his day to a far more appealing version of the same city imagined as it was about to enter the twenty-first century. Julian finds a consumers' paradise, where each citizen receives a credit card to use in selecting from a virtually limitless variety of goods available for sale at local distribution centers. With everyone receiving a per capita share of the burgeoning national output, the entire society has now become securely middle class. Indeed, there is so much wealth that citizens are actively encouraged to spend rather than save. “The nation is rich,” we are told, “and does not wish the people to deprive themselves of any good thing.” Labor unions, strikes, and class conflict have all become a distant memory. Along with the working class, the unsightly factories that once dominated so much of the urban landscape have essentially vanished. A cornucopia of goods miraculously appears, with the apparatus required for manufacturing them entirely out of sight. Given this happy state of affairs, all citizens exhibit a strong degree of patriotism. Dissent and disloyalty have become unknown, since there is no longer any need for them.

Résumé Objectif  Evaluer les soins obstétriques d'urgence et les perceptions et attentes des femmes ayant vécu l'expérience d'avoir été‘presque perdue’, dans le but d'améliorer la santé au Bénin.Méthode  Surveillance qualitative dans 7 hôpitaux dans les trois niveaux de référence de la pyramide de la santé, de juillet à octobre 2003. Nous avons utilisé deux méthodes: en premier lieu, 557 femmes qui ont été‘presque perdues’ ont été interviewées à l'hôpital et un questionnaire standard a été rempli, puis des entretiens individuels semi structurés ont été menés à domicile avec 42 de ces 557 femmes.Résultats  Les soins procurés, le logement, les services, le coût et les modalités de récupération, l'hygiène des prémices, le dynamisme, l'expertise, le soutien social, le comportement et l'attitude du personnel ont été les critères utilisés pour exprimer la satisfaction des patientes. La plupart des femmes interviewées à l'hôpital étaient satisfaites de l'accès physique, de l'organisation, du fonctionnement et de l'environnement. Cependant, les coûts excessivement élevés et les exigences de récupération des dépenses, les failles du système de référence, le manque d'empathie et la discrimination de la part du personnel infirmier, le manque de ressources d'urgence, le manque d'hygiène et de confort des prémices ont été soulignés par les femmes interviewées à domicile.Conclusion  Le système de santé maternel actuel n'arrive pas à faire face de façon effective aux complications obstétriques. Ce système a besoin d'un meilleur financement, d’être plus accessible, moins coûteux et de la prise en compte des besoins des femmes.
