CROSS-COUNTRY STUDY ON THE DETERMINANTS OF BANK FINANCIAL DISTRESS

ABSTRACTBank failures affect owners, employees, and customers, possibly causing large-scale economic distress. Thus, banks must evaluate operational risks and develop early warning systems. This study investigates bank failures in the Organization for Economic Co-operation and Development, the North America Free Trade Area (NAFTA), the Association of Southeast Asian Nations, the European Union, newly industrialized countries, the G20, and the G8. We use financial ratios to analyze and explore the appropriateness of prediction models. Results show that capital ratios, interest income compared to interest expenses, non-interest income compared to non-interest expenses, return on equity, and provisions for loan losses have significantly negative correlations with bank failure. However, loan ratios, non-performing loans, and fixed assets all have significantly positive correlations with bank failure. In addition, the accuracy of the logistic model for banks from NAFTA countries provides the best prediction accuracy regarding bank failure.

Influenza infection and Kawasaki disease

INTRODUCTION: The objective of this study was to investigate the possible link between influenza (Flu) infection and Kawasaki disease (KD). METHODS: We examined the medical records of 1,053 KD cases and 4,669 influenza infection cases hospitalized at our institute from January 1, 2011 to December 31, 2013. Cases of KD with concomitant influenza infection formed the KD + Flu group. Each KD + Flu case was matched with 2 KD cases and 2 influenza infection cases, and these cases were assigned to the KD group and Flu group, respectively. The differences in the principal clinical manifestations, course of disease, incomplete KD rate, intravenous immunoglobulin (IVIG) resistance rate, and echocardiographic detection results between the KD + Flu group and KD group were compared. The fever durations and laboratory test results of these three groups were compared. RESULTS: 1) The seasonal variations of the KD + Flu group, KD group and Flu group were similar. 2) The morbidity rate of incomplete KD was higher in the KD + Flu group compared with the KD group. 3) Patients in the KD + Flu group exhibited a longer time to KD diagnosis compared with patients in the KD group. 4) The KD + Flu group exhibited the longest fever duration among the three groups. 5) The CRP and ESR values in the KD + Flu group were higher those in the Flu or KD groups. CONCLUSIONS: Concomitant influenza infection affects the clinical manifestations of KD and can impact the laboratory test results and the diagnosis and treatment of the disease. However, it remains unclear whether influenza contributes to KD etiology.

Incidence of active mycobacterial infections in Brazilian patients with chronic inflammatory arthritis and negative evaluation for latent tuberculosis infection at baseline - A longitudinal analysis after using TNFa blockers

Several studies point to the increased risk of reactivation of latent tuberculosis infection (LTBI) in patients with chronic inflammatory arthritis (CIAs) after using tumour necrosis factor (TNF)a blockers. To study the incidence of active mycobacterial infections (aMI) in patients starting TNFa blockers, 262 patients were included in this study: 109 with rheumatoid arthritis (RA), 93 with ankylosing spondylitis (AS), 44 with juvenile idiopathic arthritis (JIA) and 16 with psoriatic arthritis (PsA). All patients had indication for anti-TNFa therapy. Epidemiologic and clinical data were evaluated and a simple X-ray and tuberculin skin test (TST) were performed. The control group included 215 healthy individuals. The follow-up was 48 months to identify cases of aMI. TST positivity was higher in patients with AS (37.6%) than in RA (12.8%), PsA (18.8%) and JIA (6.8%) (p < 0.001). In the control group, TST positivity was 32.7%. Nine (3.43%) patients were diagnosed with aMI. The overall incidence rate of aMI was 86.93/100,000 person-years [95% confidence interval (CI) 23.6-217.9] for patients and 35.79/100,000 person-years (95% CI 12.4-69.6) for control group (p < 0.001). All patients who developed aMI had no evidence of LTBI at the baseline evaluation. Patients with CIA starting TNFa blockers and no evidence of LTBI at baseline, particularly with nonreactive TST, may have higher risk of aMI.

Método de aplicação de ácido indolbutírico no enraizamento de estacas herbáceas de pessegueiro

O objetivo deste trabalho foi avaliar a capacidade de enraizamento de estacas herbáceas de pessegueiro das cultivares Delicioso Precoce, Jóia 1 e Okinawa através de diferentes métodos de aplicação exógena de ácido indolbutírico (AIB). As estacas foram obtidas em setembro de 2001 e, após o preparo, foram submetidas aos tratamentos constituídos por dois métodos de aplicação de AIB: imersão rápida da base das estacas em soluções concentradas (0; 1250; 2500 e 3750mg.L-1) por 5 segundos e imersão lenta em soluções diluídas (0; 100; 200 e 300mg.L-1) por 24 horas. Observou-se que a cultivar Jóia 1 apresentou maior enraizamento (37,3%), embora esta tenha sido estatisticamente igual à Okinawa (20,8%), ambas tratadas com soluções concentradas de AIB. Em geral, o método de imersão rápida demonstrou melhores resultados nas variáveis avaliadas neste trabalho.

2,6-di-hidroxiacetofenona no enraizamento de estacas semilenhosas de pessegueiro

A propagação do pessegueiro no Brasil baseia-se na enxertia de cultivares-copa em porta-enxertos propagados por sementes, e uma alternativa de propagação para esta frutífera poderia ser a estaquia. O objetivo deste trabalho foi avaliar o potencial de enraizamento de estacas semilenhosas de cultivares de pessegueiro através da aplicação de 2,6-di-hidroxiacetofonona (2,6-DHAP) antes do tratamento com AIB (ácido indolbutírico). As estacas foram preparadas a partir de ramos coletados das cultivares Delicioso Precoce, Jóia 1 e Okinawa, em dezembro de 2001, para serem tratadas na base com 2,6-DHAP (0 e 300mg L-1), por 4h, em aeração e depois com AIB (200mg L-1 e 2500mg L-1). As estacas foram plantadas em bandejas de poliestireno expandido com vermiculita fina e colocadas em casa de nebulização, por 45 dias. A aplicação de 300mg L-1 de 2,6-DHAP antes da aplicação de 200mg L-1 de AIB em estacas de 'Okinawa' proporcionou aumentos nos resultados das características de maior relevância para a propagação por estacas e pode ser uma técnica interessante para a estaquia em pessegueiro.

Dft theoretical study of energetic nitrogen-rich C4N6H8-n(NO2)n derivatives

Density functional theory (DFT) calculations at the B3LYP/6-31G** theoretical level were performed for a series of guanidine-fused bicyclic skeleton derivatives C4N6H8-n(NO2)n (n = 1 - 6). The heats of formation (HOFs) were calculated by isodesmic reactions, and the detonation properties were evaluated using the Kamlet - Jacobs equations. The bond dissociation energies were also analyzed to investigate the thermal stability and sensitivity of the compounds. The results show that all of the derivatives have high positive HOFs, compound G has the highest theoretical density, and compound F1 has the highest detonation velocity and detonation pressure. Considering both the detonation properties and thermal stabilities, compounds D1 and D4 (3 nitro substituents), E1 - E6 (4 nitro substituents), and G (6 nitro substituents) can be regarded as potential candidates for high-energy density materials.

A NEW HOMOGENEOUS ELECTROCATALYST FOR ELECTROCHEMICAL CARBONYLATION OF METHANOL TO DIMETHYL CARBONATE

Electrosynthesis of dimethyl carbonate (DMC) from methanol and carbon monoxide using an Cu(phen)Cl2 catalyst was achieved at room temperature and atmospheric pressure. The catalytic activity of the ligand 1,10-phenanthroline (phen) and the catalytic system were analyzed. The IR characterization results for the complex catalyst showed that copper ions were coordinated by nitrogen atoms of phen. In addition, the effects of the influencing factors, such as reaction time (t), reaction temperature (T) and the surface area of the working electrode (SWE) were studied.

Reação de híbridos de pepino a Corynespora cassiicola no Amazonas.

A mancha-alvo, causada pelo fungo Corynespora cassiicola, é a principal doença da parte área do tomateiro na região Norte do Brasil. No Estado do Amazonas o patógeno em plantas de pepino, causa severos danos à produção tanto em cultivo protegido quanto em campo aberto. O objetivo deste trabalho foi avaliar a reação de dez genótipos de pepino a C. cassiicola. O experimento foi conduzido em casa de vegetação em delineamento inteiramente ao acaso com dez tratamentos e dez repetições. Foram avaliados a cultivar Aodai e os híbridos tipo japonês General Lee F1, Hokushim, Japonês Híbrido F1 (Soudai), Jóia, Marketmore 76 (verde comprido), Natsubayashi, Natsu Suzumi, Sprint 440 II e Tsuyataro. Os isolados do patógeno foram obtidos a partir de folhas de plantas de pepino naturalmente infectadas, e multiplicado em meio de cultura BDA. As plantas foram inoculadas nas duas primeiras folhas definitivas com suspensão de inóculo na concentração 104 conídios mL-1 e mantidas em câmara úmida por 48 horas. A severidade foi avaliada e calculada a área abaixo da curva de progresso da doença (AACPD) para cada tratamento. Houve variação na reação dos genótipos ao patógeno e a cultivar Aodai apresentou menor AACPD considerada como resistente. Os híbridos Hokuchim, Soudai, Verde Comprido e Natsubayashi apresentaram menores valores de AACPD entre os híbridos avaliados em contraposição ao Tsuyataro o mais suscetível.

Delta sleep instability in children with chronic arthritis

The objective of the present study was to evaluate the expression of a cyclic alternating pattern (CAP) in slow wave sleep (SWS) in children with the well-defined chronic syndrome juvenile idiopathic arthritis (JIA). Twelve patients (9-17 years of age), 7 girls, with JIA were compared to matched controls by age, pubertal stage and gender. After one night of habituation in the sleep laboratory, sleep measurements were obtained by standard polysomnography with conventional sleep scoring and additional CAP analyses. The sleep parameters of the JIA and control groups were similar for sleep efficiency (91.1 ± 6.7 vs 95.8 ± 4.0), sleep stage in minutes: stage 1 (16.8 ± 8.5 vs 17.8 ± 4.0), stage 2 (251.9 ± 41 vs 262.8 ± 38.1), stage 3 (17.0 ± 6.0 vs 15.1 ± 5.7), stage 4 (61.0 ± 21.7 vs 77.1 ± 20.4), and rapid eye movement sleep (82.0 ± 27.6 vs 99.0 ± 23.9), respectively. JIA patients presented nocturnal disrupted sleep, with an increase in short awakenings, but CAP analyses showed that sleep disruption was present even during SWS, showing an increase in the overall CAP rate (P < 0.01). Overall CAP rate during non-rapid eye movement sleep was significantly higher in pediatric patients who were in chronic pain. This is the first study of CAP in pediatric patients with chronic arthritis showing that CAP analyses can be a powerful tool for the investigation of disturbance of SWS in children, based on sleep EEG visual analysis.

CHRNA5 polymorphism and susceptibility to lung cancer in a Chinese population

Polymorphisms in the nicotinic acetylcholine receptor subunit CHRNA5 gene have been associated with lung cancer positive susceptibility in European and American populations. In the present hospital-based, case-control study, we determined whether polymorphism in rs503464 of CHRNA5 is associated with lung cancer risk in Chinese individuals. A single nucleotide polymorphism in CHRNA5 rs503464, c.-166T>A (hereafter T>A), was identified using TaqMan-MGB probes with sequencing via PCR in 600 lung cancer cases and 600 healthy individuals. Genotype frequencies for rs503464 (T>A) were in Hardy-Weinberg equilibrium for the control population. However, genotype frequencies were significantly different between cases and controls (P < 0.05), while allele frequencies were not significantly different between groups. Compared to homozygous genotypes (TT or AA), the risk of lung cancer in those with the heterozygous genotype (TA) was significantly lower (OR = 0.611, 95%CI = 0.486-0.768, P = 0.001). Using genotype AA as a reference, the risk of lung cancer for those with genotype TA was increased 1.5 times (OR = 1.496, 95%CI = 1.120-1.997, P = 0.006). However, no difference in risk was observed between T allele carriers and A allele carriers (OR = 0.914, 95%CI = 0.779-1.073, P = 0.270). Stratification analysis showed that the protective effect of TA was more pronounced in those younger than 60 years, nonsmokers, or those without a family history of cancer, as well as in patients with adenocarcinoma or squamous cell carcinoma in clinical stages III or IV (P < 0.05). Therefore, the heterozygous genotype c.-166T>A at rs503464 of CHRNA5 may be associated with reduced risk of lung cancer, thus representing a susceptibility allele in Chinese individuals.

Serum 25-hydroxyvitamin D and biochemical markers of bone metabolism in patients with juvenile idiopathic arthritis

Our objective was to evaluate the concentrations of serum 25-hydroxyvitamin D [25(OH)D], serum calcium, serum phosphorus, alkaline phosphatase, and parathormone (PTH) in patients with polyarticular juvenile idiopathic arthritis (JIA) and to associate them with disease duration and activity, bone mineral density and use of medications. In a cross-sectional and controlled study, 30 patients with polyarticular JIA were evaluated and compared to 30 healthy individuals matched for age and gender. Clinical status, anthropometry, laboratory markers in both patients and controls, and bone mineral density, only in the patients, were measured. Of the 30 patients included in the study, 23 (76.7%) were female and 16 (53.3%) non-Caucasian; mean age was 14 years (range = 4 to 20 years). Mean disease duration was 5 years (range = 1 to 12 years). The mean concentrations of serum albumin-corrected calcium (9.04 ± 0.41 mg/dL) and alkaline phosphatase (153.3 ± 100.1 IU) were significantly lower in patients with JIA than in controls (P < 0.0001 and P = 0.001, respectively). No differences in 25(OH)D, PTH or serum phosphorus were observed between JIA and control subjects. Regarding 25(OH)D concentration, 8 patients (26.7%) and 5 controls (16.7%) had 25(OH)D concentrations compatible with deficiency (lower than 20 ng/mL) and 14 patients (46.7%) and 18 controls (60%) had concentrations compatible with insufficiency (20-32 ng/mL). These values were not associated with disease activity, use of medications or bone mineral density. We observed a high frequency of 25(OH)D insufficiency and deficiency in the study sample. The compromised bone metabolism emphasizes the importance of follow-up of JIA patients.

A three-phase epidemiological study of short and long sleepers in a middle-aged Chinese population: prevalence and characteristics

Epidemiological studies of short and long sleepers have not been conducted previously. We collected socioeconomic, psychological, and polysomnographic characteristics of 6501 parents (3252 men and 3249 women) of 4036 primary school children in Guangzhou city. The study data were collected in three phases. The overall prevalence of short (5 h or less) and long (10 h or more) sleep duration was 0.52 and 0.64%, respectively. Long sleepers had higher Eysenck Personality Questionnaire neuroticism scores [odds ratio (OR)=1.224, 95% confidence interval (CI)=1.047-1.409] and lower education levels (OR=0.740, 95%CI=0.631-0.849) than short sleepers. In the polysomnographic assessment, short, long, and normal sleepers (7-8 h) shared similar durations of Stage 3 sleep (short=25.7±10.7, long=20.3±7.9, and normal=28.0±12.8 min, F=1.402, P=0.181). In daytime multiple sleep latency tests, short sleepers (10/19, 52.6%) were more prone to have a short sleep latency (≤8 min) than long sleepers (2/23, 8.7%). In addition to different sleep durations, neuroticism might also contribute to differences between short and long sleepers in social achievements. Stage 3 sleep might be essential for humans. The short sleep latency (≤8 min) of short sleepers in multiple sleep latency tests should be interpreted cautiously, since it was of the same severity as required for a diagnosis of narcolepsy or idiopathic hypersomnia.

Negative emotions affect postoperative scores for evaluating functional knee recovery and quality of life after total knee replacement

This study aimed to determine whether psychological factors affect health-related quality of life (HRQL) and recovery of knee function in total knee replacement (TKR) patients. A total of 119 TKR patients (male: 38; female: 81) completed the Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), State Trait Anxiety Inventory (STAI), Eysenck Personality Questionnaire-revised (EPQR-S), Knee Society Score (KSS), and HRQL (SF-36). At 1 and 6 months after surgery, anxiety, depression, and KSS scores in TKR patients were significantly better compared with those preoperatively (P<0.05). SF-36 scores at the sixth month after surgery were significantly improved compared with preoperative scores (P<0.001). Preoperative Physical Component Summary Scale (PCS) and Mental Component Summary Scale (MCS) scores were negatively associated with extraversion (E score) (B=-0.986 and -0.967, respectively, both P<0.05). Postoperative PCS and State Anxiety Inventory (SAI) scores were negatively associated with neuroticism (N score; B=-0.137 and -0.991, respectively, both P<0.05). Postoperative MCS, SAI, Trait Anxiety Inventory (TAI), and BAI scores were also negatively associated with the N score (B=-0.367, -0.107, -0.281, and -0.851, respectively, all P<0.05). The KSS function score at the sixth month after surgery was negatively associated with TAI and N scores (B=-0.315 and -0.532, respectively, both P<0.05), but positively associated with the E score (B=0.215, P<0.05). The postoperative KSS joint score was positively associated with postoperative PCS (B=0.356, P<0.05). In conclusion, for TKR patients, the scores used for evaluating recovery of knee function and HRQL after 6 months are inversely associated with the presence of negative emotions.

Condicionamento fisiológico de sementes de pepino e germinação sob diferentes temperaturas

O condicionamento fisiológico é uma técnica utilizada para a embebição controlada de sementes e tem como benefícios, aumentar a rapidez e uniformidade na emergência de plântulas e a tolerância das sementes a condições ambientais adversas. O presente trabalho teve como objetivo estudar procedimentos para o condicionamento fisiológico e verificar o desempenho das sementes quando colocadas para germinar sob diferentes temperaturas. Foram utilizados lotes de sementes dos cultivares Safira e Jóia, testando-se o osmocondicionamento a -0,1MPa e -0,2MPa até que as sementes do cv. Safira atingissem o teor de água de 29%, e do cv. Jóia, 32%. Os efeitos do condicionamento foram avaliados pela porcentagem e velocidade de germinação a 15, 20, 25, 30 e 35 ºC. Verificou-se que o osmocondicionamento em papel embebido em solução de PEG -0,2MPa é benéfico ao desempenho de sementes de pepino, favorecendo a velocidade de germinação para a maioria dos lotes e temperaturas testados, com resultados mais expressivos em lotes de menor vigor expostos a temperaturas subótimas.

Procedimentos para condução de testes de vigor baseados na tolerância ao estresse térmico em sementes de pepino

O presente trabalho foi realizado com o objetivo de identificar métodos, baseados na tolerância das sementes ao estresse térmico, eficientes para a avaliação do potencial fisiológico das sementes de pepino. O trabalho foi desenvolvido em três épocas, utilizando-se lotes de sementes dos cultivares Safira e Jóia, abrangendo testes de germinação, emergência de plântulas, envelhecimento acelerado e deterioração controlada. Concluiu-se que o teste de deterioração controlada (com ajuste do teor de água para 24%, período de 48 h a 45 ºC) e de envelhecimento acelerado tradicional e com solução saturada de cloreto do sódio (a 41 ºC por 96 h) é sensível para a avaliação do potencial fisiológico de sementes de pepino.
