Iron supplementation in a large Swiss Cohort of Inflammatory Bowel Disease patients demonstrates a shift form oral to intravenous therapy over time

Background and Aims: The 2007 European Crohn's and Colitis Organization guidelines on anemia in inflammatory bowel disease (IBD) favour intravenous (iv) over oral (po) iron supplementation due to better effectiveness and tolerance. We aimed to determine the percentage of IBD patients under iron supplementation therapy and the dynamics of prescription habits (iv versus po) over time. Methods: Helsana, a leading Swiss health insurance company provides coverage for approximately 18% of the Swiss population, corresponding to about 1.2 million enrollees. Patients with Crohn's disease (CD) and ulcerative colitis (UC) were analyzed from the anonymised Helsana database. Results: In total, 629 CD (61% female) and 398 UC (57% female) patients were identified, mean observation time was 31.8 months for CD and 31.0 months for UC patients. Of the entire study population, 27.1% were prescribed iron (21.1% in males and 31.1% in females). Patients treated with IBD-specific drugs (steroids, immunomodulators, anti-TNF agents) were more frequently treated with iron compared to patients without any medication (35.0% vs. 20.9%, OR 1.91, 95%-CI 1.41-2.61). The prescription of iv iron increased from 2006/2007 (48.8% of all patients receiving any iron priscription) to 65.2% in 2008/2009 by a factor of 1.89. Conclusions: One third of the IBD population was treated with iron supplementation. A gradual shift from oral to iv iron was observed over time. This switch in prescription habits goes along with the implementation of the ECCO consensus guidelines on anemia in IBD.

Biologia de Trichogramma pretiosum Riley em ovos de Sitotroga cerealella (Olivier)

Estudaram-se, em laboratório, aspectos biológicos de Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae) em ovos do hospedeiro alternativo Sitotroga cerealella (Olivier) (Lepidoptera: Gelechiidae), visando à obtenção de informações básicas sobre a biologia desse parasitóide em condições de laboratório. Não houve controle de temperatura, umidade relativa e fotoperíodo, com o objetivo de simular as condições do Submédio do Vale do São Francisco, Estado de Pernambuco. A temperatura média registrada durante o desenvolvimento do trabalho foi 25,9±0,9°C. Os resultados mostraram uma duração média do período ovo-adulto de 9,42 dias e uma viabilidade de ovos parasitados de 88%. O número médio de T. pretiosum emergido por ovo do hospedeiro foi de 1,41, com um máximo de dois indivíduos/ovo. As fêmeas viveram, em média, 5,53 dias, enquanto os machos apresentaram longevidade média de 3,08 dias, quando ambos os sexos foram alimentados com mel puro.

Spermiogenesis and spermatozoon ultrastructure of the bothriocephalidean cestode Clestobothrium crassiceps (Rudolphi, 1819), a parasite of the teleost fish Merluccius merluccius (Gadiformes: Merlucciidae)

Spermiogenesis and the ultrastructure of the spermatozoon of the bothriocephalidean cestode Clestobothrium crassiceps (Rudolphi, 1819), a parasite of the teleost fish Merluccius merluccius (Linnaeus, 1758), have been studied by means of transmission electron microscopy. Spermiogenesis involves firstly the formation of a differentiation zone. It is characterized by the presence of two centrioles associated with striated rootlets, an intercentriolar body and an electron-dense material in the apical region of this zone. Later, two flagella develop from the centrioles, growing orthogonally in relation to the median cytoplasmic process. Flagella then undergo a rotation of 90° until they become parallel to the median cytoplasmic process, followed by the proximodistal fusion of the flagella with the median cytoplasmic process. The nucleus elongates and afterwards it migrates along the spermatid body. Spermiogenesis finishes with the appearance of the apical cone surrounded by the single helical crested body at the base of the spermatid. Finally, the narrowing of the ring of arched membranes detaches the fully formed spermatozoon. The mature spermatozoon of C. crassiceps is filiform and contains two axonemes of the 9 + '1' trepaxonematan pattern, a parallel nucleus, parallel cortical microtubules, and electron-dense granules of glycogen. The anterior extremity of the gamete exhibits a short electron-dense apical cone and one crested body, which turns once around the sperm cell. The first axoneme is surrounded by a ring of thick cortical microtubules that persist until the appearance of the second axoneme. Later, these thick cortical microtubules disappear and thus, the mature spermatozoon exhibits two bundles of thin cortical microtubules. The posterior extremity of the male gamete presents only the nucleus. Results are discussed and compared particularly with the available ultrastructural data on the former 'pseudophyllideans'. Two differences can be established between spermatozoa of Bothriocephalidea and Diphyllobothriidea, the type of spermatozoon (II vs I) and the presence/absence of the ring of cortical microtubules.

Comportamento de predação e conversão alimentar de Podisus nigrispinus sobre a traça-do-tomateiro

O objetivo deste trabalho foi avaliar o efeito da predação de Tuta absoluta (Meyrick) por ninfas e adultos de Podisus nigrispinus (Dallas) na reprodução desse predador, em casa telada (30±5ºC, 61±23% de UR e fotoperíodo natural) e em laboratório (28±1°C, 53±5% de UR e fotoperíodo de 14L:10E). Ninfas de P. nigrispinus, a partir do segundo ínstar e os adultos originados dessas ninfas, foram confinados em folhas de tomate industrial var. IPA5, com dez lagartas de terceiro ou quarto ínstares de T. absoluta. A taxa de predação do segundo ao quinto ínstar de P. nigrispinus foi de 6,2, 6,6, 8,6 e 15,5 lagartas em casa telada e de 9,1, 11,1, 8,7 e 12,9 lagartas em laboratório, respectivamente. P. nigrispinus predou, durante sua fase ninfal, um número semelhante de lagartas de T. absoluta em casa telada (38,2±1,78) e laboratório (43,1±2,19), alimentandose, em média, de 2,3 e 2,5 lagartas por dia, respectivamente, nesses dois ambientes. Fêmeas de P. nigrispinus predaram, em média, 50,8±6,1 e 50,3±10,6 lagartas no laboratório e casa telada. A conversão do alimento por fêmea de P. nigrispinus foi semelhante nos dois ambientes, tendo produzido 0,31 ovos/lagarta de T. absoluta consumida em casa telada e 0,41 ovos/lagarta em laboratório.

Biomedical risk assessment as an aid for smoking cessation.

BACKGROUND: A possible strategy for increasing smoking cessation rates could be to provide smokers who have contact with healthcare systems with feedback on the biomedical or potential future effects of smoking, e.g. measurement of exhaled carbon monoxide (CO), lung function, or genetic susceptibility to lung cancer. We reviewed systematically data on smoking cessation rates from controlled trials that used biomedical risk assessment and feedback. OBJECTIVES: To determine the efficacy of biomedical risk assessment provided in addition to various levels of counselling, as a contributing aid to smoking cessation. SEARCH STRATEGY: We systematically searched he Cochrane Collaboration Tobacco Addiction Group Specialized Register, Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (1966 to 2004), and EMBASE (1980 to 2004). We combined methodological terms with terms related to smoking cessation counselling and biomedical measurements. SELECTION CRITERIA: Inclusion criteria were: a randomized controlled trial design; subjects participating in smoking cessation interventions; interventions based on a biomedical test to increase motivation to quit; control groups receiving all other components of intervention; an outcome of smoking cessation rate at least six months after the start of the intervention. DATA COLLECTION AND ANALYSIS: Two assessors independently conducted data extraction on each paper, with disagreements resolved by consensus. MAIN RESULTS: From 4049 retrieved references, we selected 170 for full text assessment. We retained eight trials for data extraction and analysis. One of the eight used CO alone and CO + Genetic Susceptibility as two different intervention groups, giving rise to three possible comparisons. Three of the trials isolated the effect of exhaled CO on smoking cessation rates resulting in the following odds ratios (ORs) and 95% confidence intervals (95% CI): 0.73 (0.38 to 1.39), 0.93 (0.62 to 1.41), and 1.18 (0.84 to 1.64). Combining CO measurement with genetic susceptibility gave an OR of 0.58 (0.29 to 1.19). Exhaled CO measurement and spirometry were used together in three trials, resulting in the following ORs (95% CI): 0.6 (0.25 to 1.46), 2.45 (0.73 to 8.25), and 3.50 (0.88 to 13.92). Spirometry results alone were used in one other trial with an OR of 1.21 (0.60 to 2.42).Two trials used other motivational feedback measures, with an OR of 0.80 (0.39 to 1.65) for genetic susceptibility to lung cancer alone, and 3.15 (1.06 to 9.31) for ultrasonography of carotid and femoral arteries performed in light smokers (average 10 to 12 cigarettes a day). AUTHORS' CONCLUSIONS: Due to the scarcity of evidence of sufficient quality, we can make no definitive statements about the effectiveness of biomedical risk assessment as an aid for smoking cessation. Current evidence of lower quality does not however support the hypothesis that biomedical risk assessment increases smoking cessation in comparison with standard treatment. Only two studies were similar enough in term of recruitment, setting, and intervention to allow pooling of data and meta-analysis.

IV thrombolysis and statins.

Objective: To examine whether prior statin use affects outcome and intracranial hemorrhage (ICH) rates in stroke patients receiving IV thrombolysis (IVT).Methods: In a pooled observational study of 11 IVT databases, we compared outcomes between statin users and nonusers. Outcome measures were excellent 3-month outcome (modified Rankin scale 0-1) and ICH in 3 categories. We distinguished all ICHs (ICH(all)), symptomatic ICH based on the criteria of the ECASS-II trial (SICH(ECASS-II)), and symptomatic ICH based on the criteria of the National Institute of Neurological Disorders and Stroke (NINDS) trial (SICH(NINDS)). Unadjusted and adjusted odds ratios (OR) with 95% confidence intervals were calculated.Results: Among 4,012 IVT-treated patients, 918 (22.9%) were statin users. They were older, more often male, and more frequently had hypertension, hypercholesterolemia, diabetes, coronary heart disease, and concomitant antithrombotic use compared with nonusers. Fewer statin users (35.5%) than nonusers (39.7%) reached an excellent 3-month outcome (OR(unadjusted) 0.84 [0.72-0.98], p = 0.02). After adjustment for age, gender, blood pressure, time to thrombolysis, and stroke severity, the association was no longer significant (0.89 [0.74-1.06], p = 0.20). ICH occurred by trend more often in statin users (ICH(all) 20.1% vs 17.4%; SICH(NINDS) 9.2% vs 7.5%; SICH(ECASS-II) 6.9% vs 5.1%). This difference was statistically significant only for SICH(ECASS-II) (OR = 1.38 [1.02-1.87]). After adjustment for age, gender, blood pressure, use of antithrombotics, and stroke severity, the OR(adjusted) for each category of ICH (ICH(all) 1.15 [0.93-1.41]; SICH(ECASS-II) 1.32 [0.94-1.85]; SICH(NINDS) 1.16 [0.87-1.56]) showed no difference between statin users and nonusers.Conclusion: In stroke patients receiving IVT, prior statin use was neither an independent predictor of functional outcome nor ICH. It may be considered as an indicator of baseline characteristics that are associated with a less favorable course. Neurology (R) 2011;77:888-895

Com relação aos atributos agronômicos, as progênies JAB 99-17-4-9-1 e JAB 99-40-12-1-2 destacaram-se das demais por possuir médias adequadas para a maioria dos atributos. Por sua vez, na avaliação de resistência em casa de vegetação, seis progênies revelaram-se resistentes ao nematóide de cisto da soja tipo 3.

Tracheo-carinal reconstructions using extrathoracic muscle flaps.

OBJECTIVES: Prospective evaluation of tracheo-carinal airway reconstructions using pedicled extrathoracic muscle flaps for closing airway defects after non-circumferential resections and after carinal resections as part of the reconstruction for alleviation of anastomotic tension. METHODS: From January 1996 to June 2006, 41 patients underwent tracheo-carinal airway reconstructions using 45 extrathoracic muscle flaps (latissimus dorsi, n=25; serratus anterior, n=18; pectoralis major, n=2) for closing airway defects resulting from (a) bronchopleural fistulas (BPF) with short desmoplastic bronchial stumps after right upper lobectomy (n=1) and right-sided (pleuro) pneumonectomy (n=13); (b) right (n=9) and left (n=3) associated with partial carinal resections for pre-treated centrally localised tumours; (c) partial non-circumferential tracheal resections for pre-treated tracheal tumours, tracheo-oesophageal fistulas (TEF) and chronic tracheal injury with tracheomalacia (n=11); (d) carinal resections with the integration of a muscle patch in specific parts of the anastomotic reconstruction for alleviation of anastomotic tension (n=4). The airway defects ranged from 2 x 1 cm to 8 x 4 cm and involved up to 50% of the airway circumference. The patients were followed by clinical examination, repeated bronchoscopy, pulmonary function testing and CT scans. The minimum follow-up time was 6 months. RESULTS: Ninety-day mortality was 7.3% (3/41 patients). Four patients (9.7%) sustained muscle flap necrosis requiring re-operation and flap replacement without subsequent mortality, airway dehiscence or stenosis. Airway dehiscence was observed in 1/41 patients (2.4%) and airway stenosis in 1/38 surviving patients (2.6%) responding well to topical mitomycin application. Follow-up on clinical grounds, by CT scans and repeated bronchoscopy, revealed airtight, stable and epithelialised airways and no recurrence of BPF or TEF in all surviving patients. CONCLUSIONS: Tracheo-carinal airway defects can be closed by use of pedicled extrathoracic muscle flaps after non-circumferential resections and after carinal resections with the muscle patch as part of the reconstruction for alleviation of anastomotic tension.
