The analysis of GNSS signal and the use a dense network of ground-based stations allow to measure tropospheric parameters that can be used for near real-time (NRT) meteorological applications (e.g. monitoring of the delay of the neutral atmosphere and the detection of blobs of water vapour). On the other hand, the meteorological activity can impact GNSS positioning solutions. For this reason, NRT indicators of the tropospheric activity related to the disturbance of GNSS signal are required. Using a dense network of GNSS stations, this study presents a new NRT indicator based on the double differences of the ionosphere-free combination. To validate this indicator, the impact of severe weather conditions on RTK positioning solutions is shown. [less ▲]

BACKGROUND: Dynamic variables predict fluid responsiveness and may improve fluid management during surgery. We investigated whether displaying the variability in the pulse oximeter plethysmogram (pleth variability index; PVI) would guide intraoperative fluid management and improve circulation as assessed by lactate levels. METHODS: Eighty-two patients scheduled for major abdominal surgery were randomized into 2 groups to compare intraoperative PVI-directed fluid management (PVI group) versus standard care (control group). After the induction of general anesthesia, the PVI group received a 500-mL crystalloid bolus and a crystalloid infusion of 2 mL . kg(-1) . h(-1). Colloids of 250 mL were administered if the PVI was >13% Vasoactive drug support was given to maintain the mean arterial blood pressure above 65 mm Hg. In the control group, an infusion of 500 mL of crystalloids was followed by fluid management on the basis of fluid challenges and their effects on mean arterial blood and central venous pressure. Perioperative lactate levels, hemodynamic data, and postoperative complications were recorded prospectively. RESULTS: Intraoperative crystalloids and total volume infused were significantly lower in the goal-directed PVI group. Lactate levels were significantly lower in the PVI group during surgery and 48 hours after surgery (P < 0.05). CONCLUSIONS: PVI-based goal-directed fluid management reduced the volume of intraoperative fluid infused and reduced intraoperative and postoperative lactate levels. [less ▲]

Background: Postoperative organ failures commonly occur after major abdominal surgery, increasing the utilization of resources and costs of care. Tissue hypoxia is a key trigger of organ dysfunction. A therapeutic strategy designed to detect and reverse tissue hypoxia, as diagnosed by an increase of oxygen extraction (0,ER) over a predefined threshold, could decrease the incidence of organ failures. The primary aim of this study was to compare the number of patients with postoperative organ failure and length of hospital stay between those randomized to conventional vs a protocolized strategy designed to maintain O2ER < 27%. Methods: A prospective, randomized, controlled trial was performed in nine hospitals in Italy. One hundred thirty-five high-risk patients scheduled for major abdominal surgery were randomized in two groups. All patients were managed to achieve standard goals: mean arterial pressure > 80 mm Hg and urinary output > 0.5 mL/kg/h. The patients of the "protocol group" (group A) were also managed to keep O2ER < 27%. Measurements and main results: In group A, fewer patients had at least one organ failure (n = 8, 11.8%) than in group B (n = 20, 29.8%) [p < 0.05], and the total number of organ failures was lower in group A than in group B (27 failures vs 9 failures, p < 0.001). Length of hospital stay was significantly lower in the protocol group than in the control group (11.3 +/- 3.8 days vs 13.4 +/- 6.1 days, p < 0.05). Hospital mortality was similar in both groups. Conclusions: Early treatment directed to maintain O2ER at < 27% reduces organ failures and hospital stay of high-risk surgical patients. Clinical trials.gov reference No. NCT00254150. [less ▲]

Despite the proven predictive ability of bone mineral density, Fracture Risk Assessment Tool (FRAX(R)), bone turnover markers, and fracture for osteoporotic fracture, their use as targets for treatment of osteoporosis is limited. INTRODUCTION: Treat-to-target is a strategy applied in several fields of medicine and has recently become an area of interest in the management of osteoporosis. Its role in this setting remains controversial. This article was prepared following a European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis (ESCEO) working group meeting convened under the auspices of the International Osteoporosis Foundation (IOF) to discuss the feasibility of applying such a strategy in osteoporosis in Europe. METHODS: Potential targets range from the absence of an incident fracture to fixed levels of bone mineral density (BMD), a desired FRAX(R) score, a specified level of bone turnover markers or indeed changes in any one or a combination of these parameters. RESULTS: Despite the proven predictive ability of all of these variables for fracture (particularly BMD and FRAX), their use as targets remains limited due to low sensitivity, the influence of confounders and current lack of evidence that targets can be consistently reached. CONCLUSION: ESCEO considers that it is not currently feasible to apply a treat-to-target strategy in osteoporosis, though it did identify a need to continue to improve the targeting of treatment to those at higher risk (target-to-treat strategy) and a number of issues for the research agenda. These include international consensus on intervention thresholds and definition of treatment failure, further exploration of the relationship between fracture and BMD, and FRAX and treatment efficacy and investigation of the potential of short-term targets to improve adherence.

The Kabyle goat breed represents 10.52% of the total Algerian market (3.8 million heads). A survey of 69 farmers has been carried out in order to characterize it and its breeding in the District of Chemini. The questions focused on household agricultural activities, including breeding of goats, cattle, sheep, rabbits, chicken, turkeys, honeybees and the production of olive oil and figs. The goat morpho-biometric characterization was based on 18 corporal measurements. The Hierarchical Cluster Analysis (HCA) of the farm structures defined four groups of farms, variance between groups accounting for 55.7% of total variability. The average number of goats in groups 1 to 4 was 7.2±2.8, 11.1±3.5, 22.3±1.4 and 3.4±1.0, respectively. Group 3 (n=6), showed the greatest number; it consists of older farmers (67 years old or over) not practicing arboriculture. They also have the largest numbers of sheep (48.67), rabbits (50.83), chicken (48.33) and turkeys (42). Group 4 (n=9), with the lowest number of goats, was the group of young farmers (39 years old or less), more dedicated to cattle breeding (~52 heads) and the production of olive oil (~207 trees) and figs (~47 trees). The 18 morpho-biometric variables were significantly higher in males than in females (p<0.05). The Kabyle goat is small (Height at withers: male: 68.23±0.97cm and female: 65.41±0.55cm) with long hair (male: 12.24±0.51cm, and female: 9.51±0.29cm). Its ears are drooping, its convex profile has a slightly pronounced nasal split and its dress color ranges from dark brown to black. This adapted genetic resource should be key in the development of a local production, based on a strong commitment of farmers inside a breed association, for the production of specimens corresponding to a standard, to be determined collectively.

In northern Morocco, silvopastoral areas are characterized by pastoral activities, and the goats find some or all their feed rations. Overgrazing is listed as a main factor of silvopastoral degradation by local authority and several authors. Goat cannot only be regarded as a problem for silvopastoral ecosystems. A survey, with local population and local authority, were conducted in several rural communes of northern Morocco, to understand the actual factors of silvopastoral degradation. According to all interviewed persons: agriculture development, authority policy, cannabis cultivation, deforestation, drought, fire, overgrazing, population growth and soil erosion are the most cited drivers of silvopastoral degradation. Local population and local authority have the same perception that soil erosion, drought, fire and population growth are factors of silvopastoral degradation. Goat grazing can be considerate as a solution and not just a problem. In some forest areas, goat grazing contributes to a reduction of burned areas by elimination of inflammable shrubs. Herd mobility, as an ecological rationality, is considered as a response to unexpected variability in pasture production and/or animal nutritional needs. Despite all forms of degradation, silvopastoral areas in northern Morocco continue to play a support of all livestock activities, considered an inevitable source of goats feeding. [less ▲]
