Classic and Non-Classic Effects of the Duration of Supplementation of 25-Hydroxicholecalciferol in Broiler Chicken Diets.

The present study aimed to determine the effect of different times of supplementation of 25-hydroxycholecalciferol (25(OH)D3) in broiler chickens on the performance, carcass and cuts yield, bone resistance, plasma concentration of 25(OH)D3, and expression of the mTOR gene. The treatments were a control diet (CD) supplemented with 3000 IU vitamin D3/kg of feed from 1 to 46 d, or the CD + 2760 IU (69 mcg) of 25(OH)D3/kg of feed from 1 to 21 d, from 1 to 35 d, or from 1 to 46 d. The period of supplementation of 25(OH)D3 did not affect the growth performance of broilers, but the breast meat yield was linearly increased in response to increasing days of supplementation (p < 0.05). Birds supplemented with 25(OH)D3 at the time of the analysis showed an increase (p < 0.05) in the plasma concentration of 25(OH)D3 when compared to non-supplemented birds. The mTOR gene expression (p < 0.05), and breast protein deposition (p < 0.05) presented a quadratic response related to the supplementation period of 25(OH)D3. The fat content of the breast linearly decreased (p < 0.05) as the period of supplementation was extended. The results also showed a positive linear correlation between mTOR expression and 25(OH)D3 plasma levels (r = 0.593; p < 0.05).

Influence of Enzyme Supplementation in the Diets of Broiler Chickens Formulated with Different Corn Hybrids Dried at Various Temperatures.

We evaluated the influence of enzymatic supplementation on the growth performance and cecal microbiota of broilers. A total of 2160 1-day-old male chicks were used in a 3 × 2 × 2 factorial arrangement (three corn hybrids, two drying temperatures -80 and 110 °C, with or without the inclusion of an enzymatic blend (amylase, xylanase, and protease) (20 birds/pen, n = 9). For all performance and digestibility parameters, we observed, in general, isolated effects of the corn hybrids and drying temperature. Birds that received the enzymatic blend in the diet showed better weight gain from 1 to 21 days (d) and better digestibility coefficients of nutrients at 42 d. Birds fed diets with corn dried at 80 °C showed a better feed conversion ratio from 1 to 42 d. At 21 d of age, enzymatic supplementation had positive effects on jejunum morphology. Enzyme supplementation increased the abundance of the phylum Tenericutes, class Bacilli and Mollicutes, reduced Clostridia, and increased the abundances of the families Lactobacillaceae, Anaeroplasmataceae, and O_RF39;F. In conclusion, the addition of amylase, xylanase, and protease led to a better nutrient digestibility, performance, and intestinal morphology. In addition, enzyme supplementation changed the diversity, composition, and predicted function of the cecal microbiota at d 21.

Different enzymatic associations in diets of broiler chickens formulated with corn dried at various temperatures.

The effect of supplementation of different enzymatic associations in the feed of broiler chickens formulated with corn dried at 80°C or 110°C on growth performance and carcass yield was evaluated. In addition, the influence of the different enzymatic associations on the cecal microbiota was studied. One-day-old male broiler chicks (1,320) were distributed in a completely randomized design in a 2 × 5 factorial arrangement (6 replicates; 22 birds/replicate). The treatments were 2 corn drying temperatures (80°C and 110°C) and 5 diets. The diets consisted of a positive control (PC), a negative control (NC) with a reduction of 100 kcal/kg of apparent metabolizable energy, and 3 enzyme combinations added to the NC diet: amylase, amylase + xylanase, and amylase + xylanase + protease. The feed conversion ratio (FCR) from 1 to 7 d of chickens fed diets formulated with corn dried at 80°C was better (P = 0.045) than that of chickens fed diets dried at 110°C. Regardless of the enzymatic association, the supplementation improved body weight gain (P = 0.01) of the NC group to the same level as the PC group. The FCR of the NC was similar to that of the PC only when the 3 enzymes were included from 1 to 21 d (P = 0.001) and regardless of the enzymatic association for the period from 1 to 42 d (P = 0.007). Regarding cecal microbiota, the alpha diversity was similar among the groups (P > 0.05). The beta-diversity analysis showed that the microbiota of the birds receiving the combination of the 3 enzymes was similar to that of birds fed the PC diet (P = 0.18; R = 0.074), with a similar effect observed for the predicted metabolic functions (Linear discriminant analysis effect size). In conclusion, chickens fed diets formulated with corn dried at 80°C had better FCR during the prestarter phase. The enzymatic supplementation improved the FCR of the birds, which may partially be explained by the modulation of the cecal microbiota.

Analysis of factors influencing inclusion of 102 patients with stage III/IV Hodgkin's lymphoma in a randomized trial for first-line chemotherapy.

BACKGROUND: Data on factors influencing inclusion of Hodgkin's lymphoma (HL) patients in randomized clinical trials (RCT) are limited and, for the present study they were analyzed in a RCT for III/IV HL. PATIENTS AND METHODS: All patients with stage III/IV HL referred to the Saint-Louis Hospital between January 2003 and May 2007 were studied. A Groupe d'Etudes des Lymphomes de l'Adulte/European Organisation for Research and Treatment of Cancer RCT, to compare ABVD (doxorubicin, bleomycin, vinblastine, dacarbazine) with increased-dose BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, prednisone), was open for recruitment. Noninclusion criteria and physician's reasons for non-recruitment were prospectively recorded. The reasons for patient's refusal were collected retrospectively. Logistic regression analyses were carried out in order to identify factors predicting inclusion. RESULTS: A total of 102 patients were diagnosed, among whom 51% were included. Seven patients were ineligible, 22 refused to participate, and 21 were not enrolled due to the physician's decision. Main reasons for patients' refusal were standard treatment preference and concerns about experimental arm toxicity, mainly infertility risk. Conditions that could hamper accurate follow-up and toxicity concerns accounted for most of the physicians' reasons. Adverse prognostic factors [B symptoms (odds ratio, OR = 5.35) and international prognostic score > or =3 (OR = 2.69)] were independently associated with inclusion. CONCLUSION: Despite an attractive protocol, only 51% of patients were included. It highlights concerns about selection of patients and the difficulty to obtain informed consent with better prognostic profile patients.

Antibiotic sensitivity of Helicobacter pylori in Jamaica

Helicobacter pylori infection is one of the commonest chronic infections worldwide. Eradication regimes usually contain two antibiotics, however resistance is increasing and this decreases treatment success. This study reports on the sensitivity and resistance of H pylori to several antibiotics in patients undergoing upper gastrointestinal endoscopy in Jamaica. The rapid urease test (CLO) was positive in 128 (38) of 336 patients. Fifty patients (39; 50/128) with positive CLO tests had positive cultures for H pylori. Two-thirds (32/48) of islolates were sensitive to metronidazole and one-third (16/48) were resistant. Ninety-seven per cent of isolates (31/32) were sensitive to erythromycin. The sensitivity for clarithromycin was 92 (11/12) with one isolate (8) resistant. All strains of H pylori (48/48) were sensitive to ampicillin and amoxicillin - clavulanate. Metronidazole resistance is present in one-third of H pylori isolates and resistance to macrolides is relatively low in Jamaican patients. It is important to monitor antibiotic resistance in order to provide clinicians with data on the most appropriate and cost effective eradication regimes for H pylori

The sensitivity for clarithromycin was 92% (11/12) with one isolate (8%) resistant. All strains of H pylori (48/48) were sensitive to ampicillin and amoxicillin - clavulanate. Metronidazole resistance is present in one-third of H pylori isolates and resistance to macrolides is relatively low in Jamaican patients. It is important to monitor antibiotic resistance in order to provide clinicians with data on the most appropriate and cost effective eradication regimes for H pylori.

Intraosseous ganglia of the scaphoid and lunate bones: report of 15 cases in 13 patients.

Thirteen patients with 15 intraosseous carpal ganglia (6 scaphoid and 9 lunate cases) are reported. Eleven cases had cortical defects communicating the bone cysts either with the joint space or a coexisting soft tissue ganglion. Nine cysts were primary or idiopathic; soft tissue ganglia were found in 6 secondary cases and anatomic continuity of the intraosseous and extraosseous components through cortical defects was present. Treatment consisted of curettage of the cyst wall and cancellous bone grafting. Approaching lunate cysts through a small opening in the scapholunate interosseous ligament is described. Results were analyzed in 12 cases with at least 1 year of follow-up; the average follow-up period in these cases was 47 months (range, 12-119 months). Results were very good in all but 1 patient, who suffered a partial lunate collapse, which resulted in mild lunocapitate osteoarthritis. No graft reabsorption or recurrence was seen in the control radiographs obtained throughout the follow-up period.

Epidemiology of giardiasis and cryptosporidiosis in Jamaica.

We report the findings of a cross-sectional epidemiologic study of Giardia lamblia and Cryptosporidum infections in Jamaica. Three hundred twenty eight stool samples from patients less than one to 81 years of age were examined using formalin-ether concentration for G. lamblia, Zeihl-Neelsen staining for Cryptosporidium, and the Prospect rapid enzyme immunoassay (EIA; Alexon, Sunnyvale, CA) for parasite diagnosis. The Prospect Giardia rapid assay detected 17 cases of G. lamblia infection compared with six by formalin-ether concentration. However, the Prospect Cryptosporidum EIA did not increase the rate of detection of Cryptosporidum when compared with Zeihl-Neelsen staining. Cryptosporidum infections were most frequently diagnosed in children less than five years old and prevalence decreased with age. In contrast, the prevalence of giardiasis increased as children became older. There were no associations between the infections and stool consistency, clinical manifestations, or sex of the individuals. The contribution of the parasites to childhood morbidity will depend on accurate laboratory diagnosis.

Intraosseous growth of giant cell tumors of the tendon sheath (localized nodular tenosynovitis) of the digits: report of 15 cases.

Giant cell tumors of tendon sheath are common soft tissue lesions affecting the digits, sometimes causing pressure atrophy of an adjoining bone and rarely perforating the cortex to expand into the medullary canal. One hundred thirty-three cases of giant cell tumors of tendon sheath were retrospectively reviewed; 15 (11%) showed cortical perforation and intraosseous expansion. Radiographic features, diagnoses, and surgical treatment are described. The use of soft tissue radiographic techniques and mammographic films was an extremely valuable diagnostic tool, although computed tomography and magnetic resonance imaging may be necessary in some cases.

[Evaluation of a long-acting neuroleptic: penfluridol. Clinical and psychosocial evolution at a year follow-up]. / Evaluación de un neuroléptico de acción prolongada: penfluridol. Evolución clínica y psicosocial en un año de seguimiento.

Twenty schizophrenic patients were treated for a year with long term neuroleptic Penfluridol to test its antipsychotic and re-socializing effect. They underwent a clinical follow up and an evaluation of psychosocial aspects was also performed by a psychiatric social worker. Their social behaviour and reinsertion to work and family were studied by the use of specially designed scales. Clinical improvement and significant changes in all of the studied aspects of social behaviour were observed after a year of treatment. Also a reduction of treatment abandonment and of frequency of relapse through family handling was detected. Finally a number of preliminary observations on family structure and dynamics as well as changes determined on it by the treatment of the psychotic patient are summarized.
