Effect of feeding maltodextrins and dextrose on rearing and slaughtering performance of immunocastrated male pigs

This study aimed to verify previous research findings showing that feeding maltodextrins (M) and dextrose (D) leads to a reduction of voluntary feed intake in the Italian heavy pig. This may be interesting for immunocastrated pigs fed ad libitum (ad lib.), whose feed intake skyrockets after the 2nd vaccination, causing too fatty carcasses at slaughtering. Thirty-six male pigs (Italian Duroc x Italian Large White crossbred) received a double immunocastrating injection at 90 and 162 days of age. At 120 days, weighing 51.84+4.38 kg, the subjects were evenly housed in 9 boxes, fed ad lib. till the 2nd injection and then given, until slaughtering (197 days of age; 144.51±9.70 kg), one of the experimental diets: control diet, ad lib. (CL); control diet, restricted at 7.5% l.w.0.75 (CR); with MD (3.5 + 3.5%; adjusted for energy and protein), ad lib. (MD). The CR diet was introduced as the alternative choice to avoid too fatty carcasses. Compared to the restricted ones, pigs fed ad lib. (with or without MD) showed statistically higher (P<.01) ADG (1325 and 1325 vs 905 g/d), ADFI (4630 and 4637 vs 2760 g/d), feed:gain ratio (3.53 and 3.52 vs 3.11), and heavier carcasses (125.1 and 124.4 vs 113.2 kg; P<.01) with lower lean meat content (52.21 and 52.09 vs 55.83 %; P<.01). The results point out how immunocastrated pigs fed ad lib. showed similar rearing and slaughtering performance regardless of the inclusion of M and D in the diet

Neonatal malaria in Nigeria -a 2 year review

BACKGROUND: In view of the fact that a significant proportion of neonates with malaria may be missed on our wards on the assumption that the disease condition is rare, this study aims at documenting the prevalence of malaria in neonates admitted into our neonatal ward. Specifically, we hope to describe its clinical features and outcome of this illness. Knowledge of these may ensure early diagnosis and institution of prompt management. METHODS: Methods Hospital records of all patients (two hundred and thirty) admitted into the Neonatal ward of Olabisi Onabanjo University Teaching Hospital, Sagamu between 1st January 1998 and 31(st )December 1999 were reviewed. All neonates (fifty-seven) who had a positive blood smear for the malaria parasite were included in the study. Socio-demographic data as well as clinical correlates of each of the patients were reviewed. The Epi-Info 6 statistical software was used for data entry, validation and analysis. A frequency distribution was generated for categorical variables. To test for an association between categorical variables, the chi-square test was used. The level of significance was put at values less than 5%. RESULTS: Prevalence of neonatal malaria in this study was 24.8% and 17.4% for congenital malaria. While the mean duration of illness was 3.60 days, it varied from 5.14 days in those that died and and 3.55 in those that survived respectively. The duration of illness significantly affected the outcome (p value = 0.03). Fever alone was the clinical presentation in 44 (77.4%) of the patients. Maturity of the baby, sex and age did not significantly affect infestation. However, history of malaria/febrile illness within the 2 weeks preceding the delivery was present in 61.2% of the mothers. Maternal age, concurrent infection and duration of illness all significantly affected the outcome of illness. Forty-two (73.7%) of the babies were discharged home in satisfactory condition. CONCLUSION: It was concluded that taking a blood smear to check for the presence of the malaria parasite should be included as part of routine workup for all neonates with fever or those whose mothers have history of fever two weeks prior to delivery. In addition, health education of pregnant mothers in the antenatal clinic should include early care-seeking for newborns

Increased 30-Day Mortality in Very Old ICU Patients with COVID-19 Compared to Patients with Respiratory Failure without COVID-19

Purpose: The number of patients ≥ 80 years admitted into critical care is increasing. Coronavirus disease 2019 (COVID-19) added another challenge for clinical decisions for both admission and limitation of life-sustaining treatments (LLST). We aimed to compare the characteristics and mortality of very old critically ill patients with or without COVID-19 with a focus on LLST. Methods: Patients 80 years or older with acute respiratory failure were recruited from the VIP2 and COVIP studies. Baseline patient characteristics, interventions in intensive care unit (ICU) and outcomes (30-day survival) were recorded. COVID patients were matched to non-COVID patients based on the following factors: age (± 2 years), Sequential Organ Failure Assessment (SOFA) score (± 2 points), clinical frailty scale (± 1 point), gender and region on a 1:2 ratio. Specific ICU procedures and LLST were compared between the cohorts by means of cumulative incidence curves taking into account the competing risk of discharge and death. Results: 693 COVID patients were compared to 1393 non-COVID patients. COVID patients were younger, less frail, less severely ill with lower SOFA score, but were treated more often with invasive mechanical ventilation (MV) and had a lower 30-day survival. 404 COVID patients could be matched to 666 non-COVID patients. For COVID patients, withholding and withdrawing of LST were more frequent than for non-COVID and the 30-day survival was almost half compared to non-COVID patients. Conclusion: Very old COVID patients have a different trajectory than non-COVID patients. Whether this finding is due to a decision policy with more active treatment limitation or to an inherent higher risk of death due to COVID-19 is unclear.info:eu-repo/semantics/publishedVersio

The International Limits and Population at Risk of Plasmodium vivax Transmission in 2009

Growing evidence shows that Plasmodium vivax malaria is clinically less benign than has been commonly believed. In addition, it is the most widely distributed species of human malaria and is likely to cause more illness in certain regions than the more extensively studied P. falciparum malaria. Understanding where P. vivax transmission exists and measuring the number of people who live at risk of infection is a fundamental first step to estimating the global disease toll. The aim of this paper is to generate a reliable map of the worldwide distribution of this parasite and to provide an estimate of how many people are exposed to probable infection. A geographical information system was used to map data on the presence of P. vivax infection and spatial information on climatic conditions that impede transmission (low ambient temperature and extremely arid environments) in order to delineate areas where transmission was unlikely to take place. This map was combined with population distribution data to estimate how many people live in these areas and are, therefore, exposed to risk of infection by P. vivax malaria. The results show that 2.85 billion people were exposed to some level of risk of transmission in 2009

Caratterizzazione del difetto della \u201ccotenna rossa\u201ddel prosciutto di Parma

The aim of this study was to evaluate, in an objective way, the colour of the skin of raw Parma hams, classified subjectively in 3 different classes for the "red skin" defect, and to verify the relationship with muscular colour and pH. Two hundred left-thighs from pigs reared in two different farms, were evaluated subjectively on the basis of the intensity of red skin colour, using a 3 point scale system supported by a photographic standard where 1=defect absent, 2=slight defect and 3=serious defect. Colour of skin and BF muscle and pH of the latter were measured at 24 hour p.m. Results indicate that, red skin defect was present, on average, in the 69.5% of the examined thighs. L* and Hue values decreased and a* and chroma values increased, in both skin and BF tissues, when defect score increased
