No full textIAH/ACS: The Rationale for Surveillance
No full textSurveillance for intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) should be implemented in every intensive care unit (ICU), because it has been demonstrated that surveillance is effective. Several criteria that have led to the conclusion that IAH/ACS monitoring is of value: First, IAH is a frequent problem in critically ill patients that directly affects function of all organ systems to some degree, and that is associated with considerable mortality. Furthermore, simple tools for intra-abdominal pressure (IAP) monitoring are available, and it can be safely applied without the need for advanced tools. Finally, both ACS and IAH can be treated with either medical or surgical interventions. Treatment for IAH/ACS should be selected on the basis of the severity of symptoms and the cause of IAH. IAP monitoring should also be incorporated in the daily ICU management of the patient

The effect of IAH on hemodynamics.
No full text<p>Compared with the pre-IAH values, HR, CVP, and IVCP increased significantly after IAH (p<0.01), whereas SBP, DBP, and MAP decreased significantly from 0.5 h to 4 h (p<0.01); the more severe the IAH was, the more remarkable their changes. After decompression, these parameters gradually returned to normal.</p
Investigating groundwater–surface water interactions to understand hydrogeochemical processes in a carbonate mountain basin in Central Italy
No full textGroundwater (GW) – surface water (SW) interactions regulate the hydrogeochemical
processes of many rivers in the Italian central Apennine. Carbonate aquifers play a key role
in sustaining the river discharge during no-recharge periods, ensuring the ecological flow,
providing drinking water, and modulating solute exchanges related to physical-chemical
weathering processes. The Apennine Mountain basins represent sentinels for studying the
ongoing climate change in the Mediterranean area as they are scarcely anthropized. Qualiquantitative
monitoring of river waters provides essential information for understanding
hydrogeochemical processes that are often challenging to quantify. For instance, the river’s
dissolved loads are a marker for studying the consumption of atmospheric CO2 by chemical
weathering of carbonate minerals. The correlation between erosion and chemical
weathering could play a key role in the global carbon cycle, especially in the steepest
mountainous regions. To estimate the consumption of atmospheric CO2, a limestone
mountain river basin mainly fed by GW is selected. Since 2017, several parameters have
been continuously monitored, such as the discharges in some river sections, weather
parameters, electrical conductivity and water river temperature, etc. A survey by a thermal
drone during the no-recharge period allowed us to identify the river stretches fed by GW. In
the same period, discharge measures by electromagnetic devices coupled with tracer tests
and geochemical-isotopic river water data allowed the quantification of the GW component.
Moreover, a self-implemented water budget model helped to better investigate river
discharge response to rainy periods in which erosion and chemical weathering processes
are significant. By an integrated approach, the work presents the preliminary results aiming
to understand the relationship between dissolved load (e.g., alkalinity, electrical conductivity,
etc.) and the discharge in a river where GW prevails
Nitrate pollution in different hydrogeological zones of the groundwater flow system in the volcanic structure of Mt. Vulture (Basilicata, Southern Italy).
No full textA survey on groundwater quality of Mt. Vulture volcanic structure, undertaken from 2003 to 2005, indicates that nitrate pollution is a serious problem affecting the water resources. The Mt. Vulture, inactive volcano, is located on the northern border of the Basilicata region (southern Italy) and it formed in an area of strong tectonic instability. The analysis of geological, stratigraphical, hydrogeological and hydrochemical data contributes to delineate the groundwater hydrodynamics of Mt. Vulture that represents a huge aquifer characterized by precious mineral waters.
The rapid expansion of intensive agricultural activities has greatly increased the use of nitrogen (N) fertilizer. In this study has been reconstructed the map of the nitrate concentrations in groundwater.
The comparison between the winter-summer nitrate data and the intrinsic pollution vulnerability map (Spilotro et al., 2004) evidences the determining role in different hydrogeological zones of the groundwater flow system in the seasonal variations of the concentrations and in the total dilution of the pollutant

IAH: A Remembrance
No full textConstructed around ideas based on Jamaican Rastafari music and philosophy, IAH, A Remembrance, tells the story of a mother who immigrated to a foreign country to better provide for her children. The experience of reuniting with my mother and observing the ways she navigated the new country are central to the film. IAH is a poetic, essay style, experimental work in the tradition of domestic ethnographic filmmaking. I consider the way she lived alongside the philosophy of the Rastafari movement, and, also as a way of thinking about art making, freedom and Black life. </p
