Efeito de bicarbonato de sódio, feno e bagaço "in natura" sobre a digestibilidade e o desempenho de zebuínos em crescimento alimentados com bagaço de cana auto-hidrolisado

O bagaço de cana-de-açúcar "in natura" (BIN) associado ou não ao bicarbonato de sódio foi testado como substituto do feno de gramínea como fonte de fibra longa para rações de ruminantes balanceadas com altas proporções de bagaço auto-hidrolisado (BAH). A ração básica (I) continha 54% BAH; 10% milho grão; 25% farelo de algodão; 8% feno de gramínea; 0,9% calcáreo; 0,5% uréia; e 1,5% premix mineral, base seca. As rações II e III continham BIN e BIN mais bicarbonato de sódio (1,1%, base seca) respectivamente em substituição ao feno de gramínea da ração I. Foram usados bovinos Nelore machos não castrados e fêmeas (18 de cada sexo) em crescimento com médias iniciais de peso vivo e idade de 199 kg e 11 meses. O delineamento estatístico usado foi um fatorial com 3 rações e dois sexos, com dois animais por parcela. O período de adaptação foi de 15 dias e o experimental de 87 dias. Os dados para GPV (kg/dia); ingestão de MS (% PV); conversão alimentar (kg MS/Kg GPV); e pH fecal foram de: 0,909; 2,79; 7,41; e 6,46 para a ração I; 0,867; 2,65; 7,24; e 6,57 para a ração II; e 1,019; 2,88; 7,03 e 6,73 para a ração III. A ração III foi superior rações I e II para ganho de peso (P < 0,05), e apresentou um pH fecal maior do que o da ração I (P < 0,05). Os machos foram superiores às fêmeas em ganho de peso (1,044 vs 0,820; P < 0,01) e conversão alimentar (6,7vs7,7kg MS/Kg GPV; P < 0,01). Foi observada uma correlação negativa signi ficativa (P < 0,05) entre conversão alimentar e pH fecal (r =-0,50). Os elevados níveis de consumo (2,8% PV), o baixo pH do BAH (2,9 a 3,4), e a aparente baixa atividade de ruminação observados sugerem que o pH, a nível de rume e de trato digestivo inferior, é um fator limitante em dietas com altas proporções de BAH.

Growth, molt and survival of Palaemonetes argentinus (Decapoda, Caridea) under different light-dark conditions

Growth, survival and molting rate in Palaemonetes argentinus Nobili, 1901 were compared under different light-dark conditions. During 80 days, 150 immatures of both sexes (initial mean weight 0.09±0.002g), from Los Padres lagoon, Mar del Plata, Argentina, were maintained in aquaria at 19±0.4°C under three light conditions: 0:24, 10:14 and 13:11 (L-D). They were fed daily on an artificial diet (45% proteins, 17.2% lipids, 7% water, 7% ash). Good weight increment was obtained with the three treatments, finding a positive linear correlation between mean weight and time (0:24, r=0.97; 10:14, r=0.99; 13:11, r=0.98). There were no significant differences in the percentage increment in mean weight among the treatments (0:24, 19.3%; 10:14, 29.3% and 13:11, 26.5%) (p<0.05). Molting rate was significantly higher at a long-day photoperiod (MR=1.7) than at a short-day (MR=0.6) or continuous dark condition (MR=0.3) (p<0.05). The lowest survival was found in animals maintained under 13:11 L-D conditions (77%), being statistically different of the other two treatments (92% and 89% at 10:14 and 0:24, respectively) (p<0.05). These results suggest that the best growth and survival in P. argentinus result with a 10:14 L-D cycle, and that the growth is less affected by photoperiod than molting rate and survival.

Subsídio ao melhor conhecimento do tifo exantemático neotrópico no Brasil: presença do virus no leite

In articles, already published, we have proved that the strain V. B. of Brazilian virus, goes through the placenta (Macacus rhesus) (1) and the apparently normal gastro-intestinal tube (1934-1937) (Canis familiaris) (2). Today we present the idea that the Brazilian virus can reach the milk of an animal even when the latter has only the unapparent disease. In former articles (**), we have shown that the goat (Capra hircus) can be an excellent reservoir of Brazilian virus, having the strain V. B. in its blood and presenting a Weil Felix reaction high and in “group”, with the disease unapparent. When the goats are bred in the laboratory, and even in some foci of the disease, they give a negative Weil Felix, being zero for all the nine strains of Proteus. In the interior of Brazil, in many localities, goats substitute cows, in supplying milk for children and adults, and in some districts goat’s milk is considered superior to cow’s milk, possessing marvellous qualities for men, women an children. Having proved, now, that goat’s milk can contain the virus even when the animal presents nothing clinically, and having also shown that this virus goes through the digestive tube apparently sound, it is easy to understand how infants-in-arms, that is, only a few months old, living in strictly domestic surroundings, can contract the disease; we have many such cases on record. Protocol of the experiments: Goat nº 2, white, January 1948. This animal had been inoculated with the V. B. strain of the Brazilian virus in June 1947, via intra-peritoneal, presenting nothing then, not even a feverish reaction. On that occasion it was not possible to isolate the virus of the blood, although the Weil Felix reaction was positive, high and in “group”. Now January 17, 1948, seven months later, the same animal was reinoculated with a semple of virus V. B. in the same manner (intra-peritoneal) two days after bringing forth two sturdy kids. The virus V. B. was obtained from guinea-pig n. 7170 whose thermic graph was as follows: Temperatura – 38,8 – 39,1 – 39,5 – 39,4 –39,8 – 40,4 – 40,2 – 40,1 - + Necropsy – Typical lesions. The spleen weighed 5 grammes. With 3c.c. of emulsion from the nervous system of this guinea-pig, we inoculated not only the goat, as also two guineapigs, number 14 and number 5. The following is the thermic graph of one: - Guinea-pig n. 14 – 38,9 – 39,1 – 39,2 – 39.2 – 40,7 – 41,0 – 40,5 – 40,4 – 40,1 - + Typical lesions. Guinea-pig n. 2 presented the following thermic graph after the infective inoculation: - 39,5 – 39,7 – 39,7 – 39,7 – 39,5 – 39,3 – 39,5 – 39,5 – 39,5 – etc. Clinically, this animal presented nothing unusual, feeding well and suckling the kids normally. The Weil Felix reaction was positive, in “group” high very similar to the reaction obtained in June 1947, with the first infective inoculation. On the third, fourth, fifth, sixth and seventh day after the infective inoculation, we took milk from the goat and inoculated male guinea-pigs via intra-celular and via intra-peritoneal, giving 5 c.c. to each animal. Guinea-pig n. 4663, inoculated with 5 c.c. of milk, via intra-muscular, taken on the third day of the infectaive inoculation, presented the following thermic graph: - 38.8 (*) – 39,1 – 39,0 – 39,1 – 40,1 – 40,1 – 40,8 (**) – 40,8 – Killed – Typical deisions (***). The virus V. B. of this goat, circulated naturally in the blood up to the third day, having passed into the milk, producing nothing in the kids, on account of the natural resistance of these animals to the disease. The Weil Felix reaction and that of Widal for the Burcellas suis, abortus and militensis were negative for the goat and the kids. It is remarkable that, even with inoculation of the living virus after a period of seven months we cannot get a real and absolute immunity of sensitive animals. We shall return to this subject later. The hart Mazama simplicicornis may be a carrier of the virus in Brasil. The experimental serum against the virus of Exanthematic neotropical typhus has not protected guinea-pigs.

Profilaxia do tifo exantemático neotrópico no Brasil

A profilaxia racional de um doença decorre do melhor e mais profundo conhecimento dela. A do tifo exantematico neotrópico, apesar do que se sabe da doença, não e fácil no Brasil. Uma das maiores dificuldade encontramos nas distancias do nosso "hinterland" e na falta de cultura dos nossos agricultores. O homem se infecta certamente com as raças VB, VA e VA do virus brasileiro: 1.°) no campo, nas matas e nas macegas; 2.°) dentro dos domicílios ou nos arredores dêstes. Os primeiros constitúem de regra, os casos insulados do mal. Os segundos fazem parte, não raro, dos focos domiciliares macicos, com 2, 5, 7 e até 12 casos na mesma casa. São responsáveis, pelos primeiros, os carrapatos, principalmente o Amblyomma cayennense e o Amblyomma brasiliense, mormente quando no estado de ninfas, dada a herança habitual das infecções nesses artrópodos, que se infestam em animais silvestres, depositários do virus. São responsáveis pelos segundos, os "Cimex lectularius", percevejos dos leitos e as ninfas e larvas dos carrapatos, deixadas cair junto aos domicílios ou mesmo dentro deles. A profilaxia racional e completa da doença entre nós compreende: 1.°) Descarrapatização das zonas infestadas, por meio de leis apropriadas, coercitivas e aplicadas sem excepção; 2.°) Combate aos cães vadios, cabritos e outros animais portadores do virus; 3.°) Queima dos pastes, campos e macegas de fraco valor econômico, principalmente os que confinam com residências; 4.°) A propaganda racional contra esta grave doença exantemática: a) com palestras locais, acompanhadas de fotografias e gráficos expressivos e ao alcance de todos; b) pelo cinema; c) com artigos simples, claros e precisos sôbre a matéria; d) com folhetos apropriados; 5.°) Combater toda a vermina dentro e nas proximidades dos domicílios, 6.°) Demonstrar que é possível, com toda a certeza, evitar a doença, retirando os carrapatos que se prenderem ao corpo, dentro de 12 ou 14 horas após a fixação; 7.°) Aconselhar o emprego do DDT, “Gammexame" e “Toxafeno" para o expurgo das casas e animais, a fim de combater os carrapatos; 8.°) Vacinação preventiva contra a doença, quando possível, em zonas delimitadas e já civilizadas, feitas principalmente com raças de virus colhidas no Brasil e, se possível, com uma só dose. O autor trabalhou durante algum tempo com a vacina tipo Spencer-Parker. Hoje aconselha o trabalho com a vacina tipo Cox, original ou modificada.

A refratariedade das aves ao "Trypanosoma (Schizotrypanum) cruzi" I. ausência de passagem para o sangue; duração da viabilidade e destruição dos parasitos na pele

Quatro frangos e três pombos (1ª e 2ª experiências) não se infectaram com o "T. (S.) cruzi" (amostra Y), injetados na pele com doses de 9,8 x10*5 a 3,8 x 10*6 parasitos (mistura de formas de cultivo tripomastigotos sangüíneos). Em outros 2 frangos (6ª experiência), a refratariedade não foi rompida com, respectivamente, 5 injeções peritoneais em dias alternados, de 2,8 x 10*6 a 6,1 x 10*6 parasitos, e 5 injeções peritoneais diárias do conteúdo de um cultivo suspenso em salina, adicionado de tripamastigotos sangüíneos, obtidos de 3 camundongos jovens infectados. E, ainda em outros 2 frangos (7ª experiência), a refratariedade não foi rompida associando-se a doses peritoneais de 8,1 x 10*6 e 3,5 x 10*7 parasitos, respectivamente, a ministração de dexametasona, seja com o início da droga no mesmo dia da inoculação (0,4 mg/8 doses/10 dias), seja com o ínicio da droga 3dias antes do dia da inoculação (0,4 mg/10 doses/12 dias). Nessas 11 aves a refratariedade foi comprovada pela inoculação do sangue em camundongos albinos recém-nascidos (total de 54 inoculaçoes negativas em 301 camundongos); e por 52 xenodiagnósticos negativos (total de 175 larvas e adultos de Triatoma infestans e Panstrongylys megistus). As inoculações e os xenodiagnósticos foram feitos entre 1 hora (h) e 96 h e aos 10, 20 e 30 dias depois da inoculação das aves. (Quadro 1). Portanto, além da refratariedade, ficou demonstrado que os parasitos não passam para o sangue circulante das aves. em 10 frangos (3ª, 4ª e 5ª experiências) inoculados na pele com, 1,9 x 10*6 a 3,7 x 10*6 parasitos, verificou-se a duração da viabilidade dos parasitos nas áreas injetadas. Estas foram puncionadas de 1/2 com 1/2 hora, e o material obtido microscopado e inoculado em camundongos recém-nascidos. De 17 inoculações feitas até às 8:30 h, doze foram positivas, inclusive a última; e de 13 inoculações feitas entre 9 e 90 h (as 4 primeiras ainda de 1/2 em 1/2 h), todas foram negativas. Por outro lado, de 10 xenodiagnósticos feitos nas áreas injetadas, entre 1/2h e 9 h após a inoculação das aves, apenas 2 foram positivos; e de 10 xenodiagnósticos feitos entre 9 e 90 h, todos foram negativos. (Quadro 2). Em 4 frangos (8ª experiência), 10 xenodiagnósticos foram feitos entre 1 e 10 h, sendo 2 positivos (7 h e 8 h). Apesar de dificuldades operacionais na execução dos xenodiagnósticos, nas condições experimentais deste trabalho, eles se mostraram inferiores ás inoculações em camundongos recém-nascidos, como prova diagnóstica laboratorial. Portanto, verificou-se que ainda são encontrados parasitos viáveis nas áreas injetadas, pelo menos até ás 8:30 h depois inoculação. todavia, a partir de 2 h após a inoculação os parasitos diminuem de número progressivamente nas áreas injetadas, ao mesmo tempo que mostram sensíveis alterações morfológicas, encontrando-se também muito deles mortos. Ao exame direto, não mais foram vistos depois das 5:30 h. As inoculações provocam na pele dos frangos...

Cross-infection experiments with "isospora" of cats and dogs

Feces of 34 dogs out of 251 (13.5%) from guanabara were positive for Isospora. From these 19 (7.5%) were i. rivolta, 13 (5.2%) were I. canis and 2 (0,7) were i. bigemina. "Free-sporocysts" of I. rivolta were eliminated by 9 dogs (3.5%). A "Caryospora-like" oocyst was seen once. Cross-infection experiments performed with Isospora from dogs and cats failed to produce infection while inoculations of these Isospora in their natural hosts succeeded. The results suggest that the species of Isospora occurring in cats are different from those of dogs.

Daily physical activities and sports in adult survivors of childhood cancer and healthy controls: a population-based questionnaire survey.

BACKGROUND: Healthy lifestyle including sufficient physical activity may mitigate or prevent adverse long-term effects of childhood cancer. We described daily physical activities and sports in childhood cancer survivors and controls, and assessed determinants of both activity patterns. METHODOLOGY/PRINCIPAL FINDINGS: The Swiss Childhood Cancer Survivor Study is a questionnaire survey including all children diagnosed with cancer 1976-2003 at age 0-15 years, registered in the Swiss Childhood Cancer Registry, who survived ≥5 years and reached adulthood (≥20 years). Controls came from the population-based Swiss Health Survey. We compared the two populations and determined risk factors for both outcomes in separate multivariable logistic regression models. The sample included 1058 survivors and 5593 controls (response rates 78% and 66%). Sufficient daily physical activities were reported by 52% (n = 521) of survivors and 37% (n = 2069) of controls (p<0.001). In contrast, 62% (n = 640) of survivors and 65% (n = 3635) of controls reported engaging in sports (p = 0.067). Risk factors for insufficient daily activities in both populations were: older age (OR for ≥35 years: 1.5, 95CI 1.2-2.0), female gender (OR 1.6, 95CI 1.3-1.9), French/Italian Speaking (OR 1.4, 95CI 1.1-1.7), and higher education (OR for university education: 2.0, 95CI 1.5-2.6). Risk factors for no sports were: being a survivor (OR 1.3, 95CI 1.1-1.6), older age (OR for ≥35 years: 1.4, 95CI 1.1-1.8), migration background (OR 1.5, 95CI 1.3-1.8), French/Italian speaking (OR 1.4, 95CI 1.2-1.7), lower education (OR for compulsory schooling only: 1.6, 95CI 1.2-2.2), being married (OR 1.7, 95CI 1.5-2.0), having children (OR 1.3, 95CI 1.4-1.9), obesity (OR 2.4, 95CI 1.7-3.3), and smoking (OR 1.7, 95CI 1.5-2.1). Type of diagnosis was only associated with sports. CONCLUSIONS/SIGNIFICANCE: Physical activity levels in survivors were lower than recommended, but comparable to controls and mainly determined by socio-demographic and cultural factors. Strategies to improve physical activity levels could be similar as for the general population.

Extracorporeal membrane oxygenation support after heart explantation: a proposal on how to deal with hyperacute rejection of heart transplant

Purpose: In extreme situations, such as hyperacute rejection of heart transplant or major bleeding per-operating complications, an urgent heart explantation might be the only means of survival. The aim of this experimental study was to improve the surgical technique and the hemodynamics of an Extracorporeal Membrane Oxygenation (ECMO) support through a peripheral vascular access in an acardia model. Methods: An ECMO support was established in 7 bovine experiments (59±6.1 kg) by the transjugular insertion to the caval axis of a self-expanded cannula, with return through a carotid artery. After baseline measurements of pump flow and arterial and central venous pressure, ventricular fibrillation was induced (B), the great arteries were clamped, the heart was excised and right and left atria remnants, containing the pulmonary veins, were sutured together leaving an atrial septal defect (ASD) over the cannula in the caval axis. Measurements were taken with the pulmonary artery (PA) clamped (C) and anastomosed with the caval axis (D). Regular arterial and central venous blood gases tests were performed. The ANOVA test for repeated measures was used to test the null hypothesis and a Bonferroni t method for assessing the significance in the between groups pairwise comparison of mean pump flow. Results: Initial pump flow (A) was 4.3±0.6 L/min dropping to 2.8±0.7 L/min (P B-A= 0.003) 10 minutes after induction of ventricular fibrillation (B). After cardiectomy, with the pulmonary artery clamped (C) it augmented not significantly to 3.5±0.8 L/min (P C-B= 0.33, P C-A= 0.029). Finally, PA anastomosis to the caval axis was followed by an almost to baseline pump flow augmentation (4.1±0.7 L/min, P D-B= 0.009, P D-C= 0.006, P D-A= 0.597), permitting a full ECMO support in acardia by a peripheral vascular access. Conclusions: ECMO support in acardia is feasible, providing new opportunities in situations where heart must urgently be explanted, as in hyperacute rejection of heart transplant. Adequate drainage of pulmonary circulation is pivotal in order to avoid pulmonary congestion and loss of volume from the normal right to left shunt of bronchial vessels. Furthermore, the PA anastomosis to the caval axis not only improves pump flow but it also permits an ECMO support by a peripheral vascular access and the closure of the chest.

Sleep disorders in boys with Duchenne muscular dystrophy.

Aim:  Determine the frequency and predictors of sleep disorders in boys with Duchenne Muscular Dystrophy (DMD). Method:  Cross-sectional study by postal questionnaire. Sleep disturbances were assessed using the Sleep Disturbance Scale for Children (validated on 1157 healthy children). A total sleep score and six sleep disturbance factors representing the most common sleep disorders were computed. Potential associations between pathological scores and personal, medical and environmental factors were assessed. Results:  Sixteen of 63 boys (25.4%) had a pathological total sleep score compared with 3% in the general population. The most prevalent sleep disorders were disorders of initiating and maintaining sleep (DIMS) 29.7%, sleep-related breathing disorders 15.6% and sleep hyperhydrosis 14.3%. On multivariate analysis, pathological total sleep scores were associated with the need to be moved by a carer (OR = 9.4; 95%CI: 2.2-40.7; p = 0.003) and being the child of a single-parent family (OR = 7.2; 95%CI: 1.5-35.1; p = 0.015) and DIMS with the need to be moved by a carer (OR = 18.0; 95%CI: 2.9-110.6; p = 0.002), steroid treatment (OR = 7.7; 95%CI: 1.4-44.0; p = 0.021) and being the child of a single-parent family (OR = 7.0; 95%CI: 1.3-38.4; p = 0.025). Conclusion:  Sleep disturbances are frequent in boys with DMD and are strongly associated with immobility. Sleep should be systematically assessed in DMD to implement appropriate interventions.

Metabolic and respiratory effects of infused sodium acetate in healthy human subjects.

The metabolic and respiratory effects of intravenous 0.5 M sodium acetate (at a rate of 2.5 mmol/min during 120 min) were studied in nine normal human subjects. O2 consumption (VO2) and CO2 production (VCO2) were measured continuously by open-circuit indirect calorimetry. VO2 increased from 251 +/- 9 to 281 +/- 9 ml/min (P < 0.001), energy expenditure increased from 4.95 +/- 0.17 kJ/min baseline to 5.58 +/- 0.16 kJ/min (P < 0.001), and VCO2 decreased nonsignificantly (211 +/- 7 ml/min vs. 202 +/- 7 ml/min, NS). The extrapulmonary CO2 loss (i.e., bicarbonate generation and excretion) was estimated at 48 +/- 5 ml/min. This observation is consistent with 1 mol of bicarbonate generated from 1 mol of acetate metabolized. Alveolar ventilation decreased from 3.5 +/- 0.2 l/min basal to 3.1 +/- 0.2 l/min (P < 0.001). The minute ventilation (VE) to VO2 ratio decreased from 22.9 +/- 1.3 to 17.6 +/- 0.9 l/l (P < 0.005), arterial PO2 decreased from 93.2 +/- 1.9 to 78.7 +/- 1.6 mmHg (P < 0.0001), arterial PCO2 increased from 39.2 +/- 0.7 to 42.1 +/- 1.1 mmHg (P < 0.0001), pH from 7.40 +/- 0.005 to 7.50 +/- 0.007 (P < 0.005), and arterial bicarbonate concentration from 24.2 +/- 0.7 to 32.9 +/- 1.1 (P < 0.0001). These observations indicate that sodium acetate infusion results in substantial extrapulmonary CO2 loss, which leads to a relative decrease of total and alveolar ventilation.

Treatment of central retinal vein occlusion-related macular edema with intravitreal bevacizumab (Avastin): preliminary results.

PURPOSE: To assess the safety and efficacy of treatment of macular edema secondary to central retinal vein occlusion (CRVO) with intravitreal bevacizumab. PATIENTS AND METHOD: The ongoing prospective study included 8 consecutive patients (8 eyes) with macular edema secondary to CRVO (6 non ischemic and 2 ischemic), treated with intravitreal injection of 1.25 mg (0.05 mL) of bevacizumab. Main outcome was best corrected visual acuity (BCVA) and central foveal thickness (CFT) measured by optical coherence tomography monthly during one year. Retreatment criteria include decrease of BCVA, persistence of macular edema on angiograms and increase of CFT. RESULTS: Mean age of the eight patients was 68 years (range: 50-82 years). Mean duration of symptoms before injection was 98 days (range: 3-289). Mean follow-up was 3.25 months. At baseline, mean BCVA was 0.84 logMar and mean baseline CFT was 771 microm. Mean BCVA was 0.36 and mean CFT thickness was 275 microm (n = 8) at month 1, 0.41 and 411 microm at month 2 (n = 7), 0.3 and 344 microm at month 3 (n = 6), 0.3 and 397 microm at month 4 (n = 5), respectively. In 75 % of patients, a single injection was not sufficient, and retreatment needed. No serious adverse events were observed. CONCLUSIONS: Treatment of macular edema secondary to CRVO with intravitreal bevacizumab injection of 1.25 mg was well tolerated and associated with marked macular thickness reduction and BCVA improvement in all patients. A trend towards reduction of foveal thickness and improvement of visual acuity was observed in both acute and chronic CRVO.

Quality of life depends on the drinking pattern in alcohol-dependent patients.

AIMS: In patients with alcohol dependence, health-related quality of life (QOL) is reduced compared with that of a normal healthy population. The objective of the current analysis was to describe the evolution of health-related QOL in adults with alcohol dependence during a 24-month period after initial assessment for alcohol-related treatment in a routine practice setting, and its relation to drinking pattern which was evaluated across clusters based on the predominant pattern of alcohol use, set against the influence of baseline variables METHODS: The Medical Outcomes Study 36-Item Short-Form Survey (MOS-SF-36) was used to measure QOL at baseline and quarterly for 2 years among participants in CONTROL, a prospective observational study of patients initiating treatment for alcohol dependence. The sample consisted of 160 adults with alcohol dependence (65.6% males) with a mean (SD) age of 45.6 (12.0) years. Alcohol use data were collected using TimeLine Follow-Back. Based on the participant's reported alcohol use, three clusters were identified: 52 (32.5%) mostly abstainers, 64 (40.0%) mostly moderate drinkers and 44 (27.5%) mostly heavy drinkers. Mixed-effect linear regression analysis was used to identify factors that were potentially associated with the mental and physical summary MOS-SF-36 scores at each time point. RESULTS: The mean (SD) MOS-SF-36 mental component summary score (range 0-100, norm 50) was 35.7 (13.6) at baseline [mostly abstainers: 40.4 (14.6); mostly moderate drinkers 35.6 (12.4); mostly heavy drinkers 30.1 (12.1)]. The score improved to 43.1 (13.4) at 3 months [mostly abstainers: 47.4 (12.3); mostly moderate drinkers 44.2 (12.7); mostly heavy drinkers 35.1 (12.9)], to 47.3 (11.4) at 12 months [mostly abstainers: 51.7 (9.7); mostly moderate drinkers 44.8 (11.9); mostly heavy drinkers 44.1 (11.3)], and to 46.6 (11.1) at 24 months [mostly abstainers: 49.2 (11.6); mostly moderate drinkers 45.7 (11.9); mostly heavy drinkers 43.7 (8.8)]. Mixed-effect linear regression multivariate analyses indicated that there was a significant association between a lower 2-year follow-up MOS-SF-36 mental score and being a mostly heavy drinker (-6.97, P < 0.001) or mostly moderate drinker (-3.34 points, P = 0.018) [compared to mostly abstainers], being female (-3.73, P = 0.004), and having a Beck Inventory scale score ≥8 (-6.54, P < 0.001), at baseline. The mean (SD) MOS-SF-36 physical component summary score was 48.8 (10.6) at baseline, remained stable over the follow-up and did not differ across the three clusters. Mixed-effect linear regression univariate analyses found that the average 2-year follow-up MOS-SF-36 physical score was increased (compared with mostly abstainers) in mostly heavy drinkers (+4.44, P = 0.007); no other variables tested influenced the MOS-SF-36 physical score. CONCLUSION: Among individuals with alcohol dependence, a rapid improvement was seen in the mental dimension of QOL following treatment initiation, which was maintained during 24 months. Improvement was associated with the pattern of alcohol use, becoming close to the general population norm in patients classified as mostly abstainers, improving substantially in mostly moderate drinkers and improving only slightly in mostly heavy drinkers. The physical dimension of QOL was generally in the normal range but was not associated with drinking patterns.

Observations on some Avian Coccidia (Apicomplexa: Eimeriidae) in Amazonian Brazil

Oocysts of Eimeria porphyrulae n. sp. are described in faeces of Porphyrula martinica (Aves: Gruiformes: Rallidae). They are ellipsoidal to oval, 22.4 x 17.7 (20.0-23.7 x 16.2-18.7) µm, shape-index (length/width) 1.3. Oocyst wall about 1.25 µm thick, colourless, with two layers: inner one prominently striated.
