Risk of suicide among operated and non-operated patients hospitalised for peptic ulcers

Background: Some small studies have reported high risk of suicide after surgical treatment for peptic ulcer. The aim of the present study was to explore the risk of suicide in hospitalised gastric ulcer and duodenal ulcer patients separately among operated and non-operated cohorts. Methods: Retrospective cohorts of 163 579 nonoperated patients with gastric ulcer or duodenal ulcer and 28 112 patients with surgical treatment for ulcer, recorded in the Swedish Inpatient Register since 1965, were followed from the first hospitalisation, or operation for the surgery cohort, until death, any cancer, emigration, or 31 December 2003. Standardised mortality ratios (SMRs) were calculated, and Poisson regression produced adjusted relative risk estimates among operated and non-operated patients. Results: Non-operated patients hospitalised for peptic ulcer showed a 70% excess risk of suicide (SMR 1.7, 95% CI 1.6 to 1.9) and those who underwent operation had a 60% increased risk (SMR 1.6, 95% CI 1.4 to 1.8). The risk of suicide was very high during the first year after hospitalisation (SMR 4.0, 95% CI 3.4 to 4.7) and more marked among women, patients under 70 and patients hospitalised without complications of ulcer. Both gastric ulcer and duodenal ulcer patients had high risk of suicide completion. Conclusion: Hospitalised patients with gastric ulcer or duodenal ulcer have an increased risk of suicide regardless of surgical treatment. These patients, especially women, are at very high risk during the first year after first hospitalisation/operation. The evaluation and management of suicidal thoughts in patients in medical settings should be further considered

Potential energy surfaces of superheavy nuclei

We investigate the structure of the potential energy surfaces of the superheavy nuclei 258Fm, 264Hs, (Z=112,N=166), (Z=114,N=184), and (Z=120,N=172) within the framework of self-consistent nuclear models, i.e. the Skyrme-Hartree-Fock approach and the relativistic mean-field model. We compare results obtained with one representative parametrisation of each model which is successful in describing superheavy nuclei. We find systematic changes as compared to the potential energy surfaces of heavy nuclei in the uranium region: there is no sufficiently stable fission isomer any more, the importance of triaxial configurations to lower the first barrier fades away, and asymmetric fission paths compete down to rather small deformation. Comparing the two models, it turns out that the relativistic mean-field model gives generally smaller fission barriers.Comment: 8 pages RevTeX, 6 figure

Teor de minerais em tíbias de frangos de corte alimentados com dietas que utilizaram farelo de trigo e fitase na sua composição.

Alimentos alternativos ao milho e farelo de soja tem sido buscados constantemente pela cadeia de produção de aves. Para tanto é importante que sejam de baixo custo, fácil disponibilidade e permitam um desempenho satisfatório de desempenho quando utilizados nas dietas. De acordo com Rostagno (2005), o farelo de trigo apresenta composição nutricional adequada, entretanto possui frações compostas por fatores antinutricionais que podem acarretar a formação de complexos, reduzindo a biodisponibilidade de nutrientes. A inclusão da fitase pode melhorar o aproveitamento deste ingrediente, proporcionando a liberação de nutrientes essenciais ao metabolismo dos animais, como o fósforo, fundamental para a mineralização óssea. O objetivo do presente trabalho foi avaliar o efeito do farelo de trigo e da fitase na dieta sobre o teor de matéria mineral, cálcio e fósforo e a relação Ca:P da tíbia de frangos de corte aos 32 dias de idade

Qualidade externa de ovos de codornas de postura alimentadas com farelo de arroz integral em diferentes.

A alimentação representa 70% dos custos de uma produção animal, independente do tamanho e da destinação da mesma. Como principais alimentos fornecidos as aves tem-se o milho, farelo de soja e para redução destes custos torna-se interessante o uso de alimentos alternativos. O arroz é um dos grãos mais produzidos em todo o mundo, sendo o Brasil o décimo maior produtor mundial. Santos et al. (2004) afirmam que o FAI é uma matéria-prima disponível no mercado brasileiro, e pode ser utilizado nas dietas, para diminuir os custos de produção, substituindo o milho, que é a matéria-prima que mais dispende custos às rações avícolas. O farelo de arroz integral (FAI), resultante do polimento dos grãos de arroz, é o mais usado na criação de suínos e aves, considerando os farelos de arroz integral e desengordurado como os subprodutos da indústria do arroz que têm sido incluídos nas dietas de aves (Filardi et al, 2007). A presença de elevada quantidade de gordura, constituída principalmente de ácidos graxos insaturados, predispõe à peroxidação, favorecendo a multiplicação de fungos produtores de aflatoxinas e a rancificação oxidativa, que compromete a qualidade do FAI e dificulta o armazenamento de grandes quantidades. Como forma de prevenir a perda do produto, existem no mercado aditivos químicos e orgânicos. Com isso o objetivo do trabalho foi avaliar a qualidade externa dos ovos de codornas alimentadas com farelo de arroz integral armazenado em diferentes tempos

Superheavy nuclei in selfconsistent nuclear calculations

The shell structure of superheavy nuclei is investigated within various parametrizations of relativistic and nonrelativistic nuclear mean field models. The heaviest known even-even nucleus 264Hs is used as a benchmark to estimate the predictive value of the models. From that starting point, doubly magic spherical nuclei are searched in the region Z=110-140 and N=134-298. They are found at (Z=114, N=184), (Z=120, N=172), or at (Z=126, N=184), depending on the parametrization.Comment: 16 pages RevTeX, 2 tables, 2 low resolution Gif figures (high resolution PostScript versions are available at http://www.th.physik.uni-frankfurt.de/~bender/nucl_struct_publications.html or at ftp://th.physik.uni-frankfurt.de/pub/bender ), submitted to Phys.

Nuclear Ground State Observables and QCD Scaling in a Refined Relativistic Point Coupling Model

We present results obtained in the calculation of nuclear ground state properties in relativistic Hartree approximation using a Lagrangian whose QCD-scaled coupling constants are all natural (dimensionless and of order 1). Our model consists of four-, six-, and eight-fermion point couplings (contact interactions) together with derivative terms representing, respectively, two-, three-, and four-body forces and the finite ranges of the corresponding mesonic interactions. The coupling constants have been determined in a self-consistent procedure that solves the model equations for representative nuclei simultaneously in a generalized nonlinear least-squares adjustment algorithm. The extracted coupling constants allow us to predict ground state properties of a much larger set of even-even nuclei to good accuracy. The fact that the extracted coupling constants are all natural leads to the conclusion that QCD scaling and chiral symmetry apply to finite nuclei.Comment: 44 pages, 13 figures, 9 tables, REVTEX, accepted for publication in Phys.

The structure of superheavy elements newly discovered in the reaction of 86^{86}Kr with 208^{208}Pb

The structure of superheavy elements newly discovered in the $^{208}$Pb($^{86}$Kr,n) reaction at Berkeley is systematically studied in the Relativistic Mean Field (RMF) approach. It is shown that various usually employed RMF forces, which give fair description of normal stable nuclei, give quite different predictions for superheavy elements. Among the effective forces we tested, TM1 is found to be the good candidate to describe superheavy elements. The binding energies of the $^{293}$118 nucleus and its $\alpha-$decay daughter nuclei obtained using TM1 agree with those of FRDM within 2 MeV. Similar conclusion that TM1 is the good interaction is also drawn from the calculated binding energies for Pb isotopes with the Relativistic Continuum Hartree Bogoliubov (RCHB) theory. Using the pairing gaps obtained from RCHB, RMF calculations with pairing and deformation are carried out for the structure of superheavy elements. The binding energy, shape, single particle levels, and the Q values of the $\alpha-$decay $Q_{\alpha}$ are discussed, and it is shown that both pairing correlation and deformation are essential to properly understand the structure of superheavy elements. A good agreement is obtained with experimental data on $Q_{\alpha}$. %Especially, the atomic number %dependence of $Q_{\alpha}$ %seems to match with the experimental observationComment: 19 pages, 5 figure

Acute coronary syndrome in patients younger than 30 years--aetiologies, baseline characteristics and long-term clinical outcome.

Coronary atherosclerosis begins early in life, but acute coronary syndromes in adults aged <30 years are exceptional. We aimed to investigate the rate of occurrence, clinical and angiographic characteristics, and long-term clinical outcome of acute coronary syndrome (ACS) in young patients who were referred to two Swiss hospitals. From 1994 to 2010, data on all patients with ACS aged <30 years were retrospectively retrieved from our database and the patients were contacted by phone or physician's visit. Baseline, lesion and procedural characteristics, and clinical outcome were compared between patients in whom an underlying atypical aetiology was found (non-ATS group; ATS: atherosclerosis) and patients in whom no such aetiology was detected (ATS group). The clinical endpoint was freedom from any major adverse cardiac event (MACE) during follow-up. A total of 27 young patients with ACS aged <30 years were admitted during the study period. They accounted for 0.05% of all coronary angiograms performed. Mean patient age was 26.8 ± 3.5 years and 22 patients (81%) were men. Current smoking (81%) and dyslipidaemia (59%) were the most frequent risk factors. Typical chest pain (n = 23; 85%) and ST-segment elevation myocardial infarction (STEMI; n = 18 [67%]) were most often found. The ATS group consisted of 17 patients (63%) and the non-ATS group of 10 patients (37%). Hereditary thrombophilia was the most frequently encountered atypical aetiology (n = 4; 15%). At 5 years, mortality and MACE rate were 7% and 19%, respectively. ACS in young patients is an uncommon condition with a variety of possible aetiologies and distinct risk factors. In-hospital and 5-year clinical outcome is satisfactory
