Operativni sustav za prognoziranje hipoksije u sjevernom Jadranu
The northern Adriatic Sea (NA), the northernmost region of the Mediterranean Sea, is affected by strong anthropogenic pressure (e.g., tourism, fisheries, maritime traffic, discharge from agriculture and industry), superimposed to a large river runoff. The consequent pressure exerted on the NA ecosystem either triggers or worsens massive mucilage insurgence, harmful algal blooms, eutrophication and even anoxic/hypoxic events. This work focuses on the anoxic/hypoxic events. During the summer-autumn period, the NA is often exposed to these events, which can be categorised as either coastal (relatively frequent south of the Po River delta during the summer) and offshore (rare, affecting wider areas). In order to improve our knowledge about these processes and to meet the needs of local governments and decision makers, an operational system for monitoring and forecasting anoxic and hypoxic events
has been set up in the framework of the EU LIFE "EMMA" project. The system is composed of a meteo-oceanographic buoy; a numerical prediction system based on the Regional Ocean Modelling System (ROMS), including a Fasham-type module for biogeochemical fluxes; and periodic oceanographic surveys. Every day since June 2007, the system provides 3-hourly forecasts of marine currents, thermohaline and biogeochemical fields for the incoming three days. The system has demonstrated its ability to produce accurate temperature forecasts and relatively good salinity and dissolved oxygen forecasts. The Root Mean Square Error of the dissolved oxygen forecast was largely due to the mean bias. The system is currently being improved to include a better representation of benthic layer biogeochemical processes and several adjustments of the model. While developing model improvements, dissolved oxygen forecasts were improved with the removal of the 10-day mean bias.Sjeverni Jadran (NA), najsjeverniji dio Sredozemnog mora, pod utjecajem je jakog antropogenog djelovanja (poput turizma, ribarenja, morskog prometa, istjecanje onečišćujućih tvari u poljoprivredi i industriji) te dodatno, velikog dotoka rijeka. Posljedično, djelovanje na NA ekosustav potiče ili pojačava uzdizanje sluzavih nakupina, štetno cvjetanje algi, eutrofikaciju pa čak i događaje anoksije/hipoksije. Ovaj se rad fokusira na anoksiju/hipoksiju. Tijekom ljetno-jesenskog razdoblja, NA je često izložen ovim doga|ajima, koji se mogu kategorizirati kao obalni (relativno učestali južno od delte rijeke Po ljeti) ili udaljeni od obale (rijetki, zahvaćajući šira područja). Kako bi poboljšali poznavanje tih procesa te zbog potreba lokalne uprave, uspostavljen je operativni sustav za praćenje i prognoziranje anoksije i hipoksije u okviru EU LIFE "EMMA" projekta. Sustav se sastoji od meteorološko-oceanografske plutače; sustava za numeričku prognozu, koji se temelji na regionalnom oceanografskom modelu (ROMS), uključujući modul Fasham-tipa za biogeokemijske tokove; i periodičnim oceanografskim istraživanjima. Svakog dana, počev od lipnja 2007, sustav omogućava 3-satne prognoze morskih struja te termohalina i biogeokemijska polja za sljedeća tri dana. Sustav se pokazao sposobnim za davanje točnih prognoza temperature i relativno dobrih prognoza saliniteta i otopljenog kisika. Korijen srednje kvadratne pogreške prognoziranog otopljenog kisika postojao je uglavnom zbog srednje pristranosti (biasa). Sustav je trenutno poboljšan tako da uključuje bolji prikaz biogeokemijskih procesa u području sloja bentosa i nekoliko prilagodba modela. Tijekom poboljšavanja modela, uklanjanjem 10-dnevne srednje pristranosti (biasa) poboljšane su prognoze otopljenog kisika

L’utilizzo del Lat Gel nell’anestesia locale delle ferite pediatriche in Pronto Soccorso
Sedation and analgesia are common strategies to manage acute procedural pain and anxiety in Emergency Department, but no standardized protocol in children is approved. Application of topical LATgel (Lidocaine 4%, Adrenaline 0,05%, Tetracaine 0,5%) on wounds before painful procedures seems to be as effective as intradermal infiltrations in reducing procedural pain. A review of 34 paediatric cases from Pavullo Hospital (MO, Italy) presenting with laceration requiring suture was conducted. Pain assessment was performed in triage and, after 30mins of LATgel application, from parents, children and doctors during the suture. LATgel administration improves children’s compliance, minimizing pain and related fear during procedures. Our findings are consistent with international literature

Prevalence and risk factors for Hepatitis C and HIV-1 infections among pregnant women in Central Brazil
<p>Abstract</p> <p>Background</p> <p>Hepatitis C (HCV) and human immunodeficiency virus (HIV) infections are a major burden to public health worldwide. Routine antenatal HIV-1 screening to prevent maternal-infant transmission is universally recommended. Our objectives were to evaluate the prevalence of and potential risk factors for HCV and HIV infection among pregnant women who attended prenatal care under the coverage of public health in Central Brazil.</p> <p>Methods</p> <p>Screening and counselling for HIV and HCV infections was offered free of charge to all pregnant women attending antenatal clinic (ANC) in the public health system, in Goiania city (~1.1 million inhabitants) during 2004–2005. Initial screening was performed on a dried blood spot collected onto standard filter paper; positive or indeterminate results were confirmed by a second blood sample. HCV infection was defined as a positive or indeterminate sample (EIA test) and confirmed HCV-RNA technique. HIV infection was defined according to standard criteria. Factors associated with HIV and HCV infections were identified with logistic regression. The number needed to screen (NNS) to prevent one case of infant HIV infection was calculated using the Monte Carlo simulation method.</p> <p>Results</p> <p>A total of 28,561 pregnant women were screened for HCV and HIV-1 in ANC. Mean maternal age was 23.9 years (SD = 5.6), with 45% of the women experiencing their first pregnancy. Prevalence of HCV infection was 0.15% (95% CI 0.11%–0.20%), and the risk increased with age (p < 0.01). The prevalence of anti-HIV infection was 0.09% (95% CI 0.06%–0.14%). Black women had a 4.9-fold (95% CI 1.42–16.95) greater risk of HIV-1 infection compared to non-black women. NNS to prevent one case of infant HIV infection ranged from 4,141 to 13,928.</p> <p>Conclusion</p> <p>The prevalence of HIV and HCV infections were low among pregnant women, with high acceptability rates in the opt-in strategy in primary care. Older maternal age was a risk factor for HCV and antenatal HCV testing does not fulfill the requirements for screening recommendation. The finding of higher risk of HIV-1 infection among black women despite being in consonance with the HIV-1 ethnic pattern in some American regions cannot be ruled out to be a surrogate marker of socio-economic condition.</p
