To this end, a cross-sectional survey was carried out on 87 breeding in these towns. A Discriminant Factorial Analysis (DFA) confirming a k-means classification of the data collected was used to retain 71 breeding divided into three breeding classes: Class A (32.4% of breeding), Class B (14.08%) and Class C (53.52%). The results show that the majority of pig breeders were men between the ages of 36 and 59. Average herd sizes were 35 ± 28;79 ± 42 and 89 ± 21 pigs for Classes A, B and C respectively. The main breeds of pig found on the breeding were crossbred, Large white, local, Landrace and Duroc. Class A (26.1%), B (30%) and C (15.8%) breeders were familiar with both lysine and methionine. Class A breeders distributed feed staggered (65.2%) and in rations (34.8%). Lysine (13%) and methionine (8.7%) were purchased at 5250 FCFA/kg. Those in class B distributed feed staggered (50%) and in the form of rations (50%), in which they incorporated lysine (30%) and methionine (30%) purchased at a cost of 2500 FCFA/kg and 3000 FCFA/kg respectively. Rationing and staggered feeding were practiced by 23.7% and 76.3% of Class C breeders respectively. Only lysine purchased at 3400 FCFA/kg was incorporated into rations by 10.5% of breeders. The high cost of lysine and methionine was incriminated by Class A (100%), B (33.3%) and C (50%) breeders. In conclusion, intensive pig breeding, the practice of rationing and the incorporation of the amino acids lysine and methionine are of ascending importance from classes C, A to B. The high cost of feedstuffs, particularly lysine and methionine, compromises their use in rations, which could have a negative impact on expected breeding performance. The screening and use of feeds rich in and/or enriched with these amino acids, through the development or adaptation of technologies, could improve the efficiency of rations and the productivity of intensive pig breeding in Burkina Faso.展开更多

The questionnaire was developedand reviewed by physicians with expertise in pediatric critical care, disasterreadiness, human factors, and survey development. Thirty-five children’shospitals were identified for recruitment through a long-established nationalresearch network. The questions focused on six themes: (1) PICU and medicaldirector demographics;(2) Pediatric patient flow during the pandemic;(3)Changes to the staffing models related to the pandemic;(4) Use of personalprotective equipment (PPE);(5) Changes in clinical practice and innovations;and(6) Current modalities of training including simulation.RESULTSWe report on survey responses from 22 of 35 PICUs (63%). The majority of PICUswere located within children’s hospitals (87%). All PICUs cared for pediatricpatients with COVID-19 at the time of the survey. The majority of PICUs (83.4%)witnessed decreases in non-COVID-19 patients, 43% had COVID-19 dedicatedunits, and 74.6% pivoted to accept adult COVID-19 patients. All PICUsimplemented changes to their staffing models with the most common changesbeing changes in COVID-19 patient room assignment in 50% of surveyed PICUsand introducing remote patient monitoring in 36% of the PICU units. Ninety-fivepercent of PICUs conducted training for donning and doffing of enhanced PPE.Even 6 months into the pandemic, one-third of PICUs across the United Statesreported shortages in PPE. The most common training formats for PPE werehands-on training (73%) and video-based content (82%). The most commonconcerns related to COVID-19 practice were changes in clinical protocols andguidelines (50%). The majority of PICUs implemented significant changes in theirairway management (82%) and cardiac arrest management protocols in COVID-19patients (68%). Simulation-based training was the most commonly utilizedtraining modality (82%), whereas team training (73%) and team dynamics (77%)were the most common training objectives.CONCLUSIONSA substantial proportion of surveyed PICUs reported on large changes in theirpreparedness and training efforts before and during the pandemic. PICUsimplemented broad strategies including modifications to staffing, PPE usage,workflow, and clinical practice, while using simulation as the preferred trainingmodality. Further research is needed to advance the level of preparedness,support staff assuredness, and support deep learning about which preparednessactions were effective and what lessons are needed to improve PICU care andstaff protection for the next COVID-19 patient waves.展开更多

We used an online questionnaire to record general data about each participating ICU, including the type of hospital, number of beds, staff ratios, and RRT implementation. Each center then prospectively recorded RRT parameters from 5 consecutive acute kidney injury (AKI) patients, namely the indication, type of dialysis catheter used, type of catheter lock used, type of RRT (continuous or intermittent), the RRT parameters initially prescribed (dose, blood flow, and duration), and the anticoagulant agent used for the circuit.Results:A total of 303 patients from 67 ICUs were analyzed. Main indications for RRT were oligo-anuria (57.4%), metabolic acidosis (52.1%), and increased plasma urea levels (47.9%). The commonest insertion site was the right internal jugular (45.2%). In 71.0% of cases, the dialysis catheter was inserted by a resident. Ultrasound guidance was used in 97.0% and isovolumic connection in 90.1%. Citrate, unfractionated heparin, and saline were used as catheter locks in 46.9%, 24.1%, and 21.1% of cases, respectively.Conclusions:Practices in French ICUs are largely compliant with current national guidelines and international literature. The findings should be interpreted in light of the limitations inherent to this type of study.展开更多

文摘Various kinds of human disturbances on cropland are the main reasons for soil erosion and land degradation.Farming practices in mountainous areas vary greatly among cropland plots because of the heterogeneity of biophysical conditions and differences in farmers'management behavior.The main purpose of this paper is to develop a composite index of cropland physical disturbance intensity(CLDI)to reflect the plot-scale discrepancy of potential soil erosion in mountainous areas.The study was based on both plot survey and household interview data,collected from six typical catchments in mountainous areas of southwestern China.Four kinds of physical disturbance practices and two kinds of conservation practices during one crop rotation period were synthesized to develop the CLDI index.The rough set theory was referenced to avoid subjectivity during weight allocation.The results show that conventional tillage,deep fertilization,and manual weeding are the main causes of cropland soil erosion,whereas manure application in combination with seasonal fallow reduces soil erosion.Different crop types as well as cropland location factors determine the spatial pattern of CLDI.Crop rotation modes with major crops of tobacco and maize resulted in a maximal CLDI,and cropland plots with a distance radius of 150 meters away from households received the most intensive physical disturbance.These results are critical to help better protect rural environments in mountainous areas.Based on the results,methods to reduce cropland soil erosion are suggested.
