Management of Mechanical Ventilation in Decompensated Heart Failure.
Mechanical ventilation (MV) is a life-saving intervention for respiratory failure, including decompensated congestive heart failure. MV can reduce ventricular preload and afterload, decrease extra-vascular lung water, and decrease the work of breathing in heart failure. The advantages of positive pressure ventilation must be balanced with potential harm from MV: volutrauma, hyperoxia-induced injury, and difficulty assessing readiness for liberation. In this review, we will focus on cardiac, pulmonary, and broader effects of MV on patients with decompensated HF, focusing on practical considerations for management and supporting evidence

Inarijärven tilan kehittyminen vuosina 1960–2009
Inarijärvestä on olemassa kohtuullisen hyvin tutkimus- ja seurantatietoa usean vuosikymmenen ajalta, mikä antaa hyvät mahdollisuudet järven tilaa ja sen kehittymistä kuvaavien mittareiden kehittämiseen ja hyödyntämiseen.
Työssä pyrittiin löytämään tutkimus- ja seuranta-aineistoon perustuvia mittareita, jotka kuvaavat monipuolisesti Inarijärven tilaa ja käyttöä, etenkin järven yleisiä hydrologisia ja meteorologisia olosuhteita ja niiden kehittymistä (ilmastonmuutos), järveen tulevaa kuormitusta ja veden laatua, virkistyskäyttöä, rantavyöhykkeen eliöyhteisöjen tilaa, kalakantoja ja kalastusta sekä säännöstelykäytäntöä ja säännöstelyn vaikutuksia. Tavoitteena oli kuvata myös eri muuttujien välisiä vuorovaikutuksia.
2000-luvulla toteutetulla Inarijärven vesiluonnon tilan kannalta aikaisempaa paremmalla säännöstelykäytännöllä on parannettu virkistyskäytön olosuhteita kesällä ja osittain vähennetty säännöstelyn aiheuttamia haittoja rantavyöhykkeen eliöstöön. Vesistön tilan ja käytön kannalta eniten myönteisiä muutoksia on tapahtunut kalakannoissa. Punalihaisten petokalojen saaliit, yksikkösaaliit ja saaliskalojen koko ovat suurentuneet 2000-luvulla hyvän muikkukannan ja tuloksellisten istutusten ansiosta. Inarijärven hydrologisissa mittareissa on havaittavissa merkkejä ilmaston lämpenemisestä.
Julkaisu tarjoaa kattavan yhteenvedon Inarijärven tilasta ja sen kehittymisestä viime vuosikymmeninä. Raportin tuloksia voidaan hyödyntää mm. säännöstelykäytännön ja kalaston hoidon kehittämisessä sekä matkailussa, opetuksessa ja yleisessä viestinnässä. Tarkastelu tukee myös vesienhoitotyötä, koska se auttaa ymmärtämään biologisten laatutekijöiden tilaan vaikuttavia tekijöitä ja selittämään syitä järven ekologisen tilan kehityssuunnille. Työssä kehitettyä lähestymistapaa ja mittareita voidaan soveltuvin osin hyödyntää myös muissa vesistöissä
Isolation of KPC 3-producing Enterobacter aerogenes in a patient colonized by MDR Klebsiella pneumoniae
We describe the interspecies transmission of the plasmid-mediated blaKPC-3 gene, which confers carbapenem resistance, between clinically relevant gram-negative bacteria in a single patient. A KPC-3 producing Enterobacter aerogenes was isolated from a hospitalized patient previously colonized and then infected by a Klebsiella pneumoniae ST101 carrying the blaKPC-3 gene. The strains showed identical plasmids. Since intense horizontal exchanges among bacteria can occur in the gut, clinicians should be aware that patients colonized by carbapenem-resistant K. pneumoniae could become carriers of other carbapenem-resistant Enterobacteriaceae. © 2016 by Edimes - Edizioni Internazionali Srl.

Surgical site infection after caesarean section. Space for post-discharge surveillance improvements and reliable comparisons
Surgical site infections (SSI) after caesarean section (CS) represent a substantial health system concern. Surveying SSI has been associated with a reduction in SSI incidence. We report the findings of three (2008, 2011 and 2013) regional active SSI surveillances after CS in community hospital of the Latium region determining the incidence of SSI. Each CS was surveyed for SSI occurrence by trained staff up to 30 post-operative days, and association of SSI with relevant characteristics was assessed using binomial logistic regression. A total of 3,685 CS were included in the study. A complete 30 day post-operation follow-up was achieved in over 94% of procedures. Overall 145 SSI were observed (3.9% cumulative incidence) of which 131 (90.3%) were superficial and 14 (9.7%) complex (deep or organ/space) SSI; overall 129 SSI (of which 89.9% superficial) were diagnosed post-discharge. Only higher NNIS score was significantly associated with SSI occurrence in the regression analysis. Our work provides the first regional data on CS-associated SSI incidence, highlighting the need for a post-discharge surveillance which should assure 30 days post-operation to not miss data on complex SSI, as well as being less labour intensive
Short-term economic impact of the Zika virus outbreak
Summary
Zika virus (ZIKV) is mainly transmitted by mosquitoes bites. However, transmission by sexual contacts
has been reported in 11 non endemic countries. The rapid spread of ZIKV in Latin American and Caribbean
Countries (LCR), person-to-person transmission and perceived risk on people’s well being can
affect the emerging economies of LCR which historically dependent on truism. Here we present an
analysis on economic outputs for assessing the current impact of ZIKV on markets. Our analysis show
an unexpected resilience of LCR markets to international alerts. This positive response represents an
opportunity to scale-up interventions for preventing the further spreading of the ZIKV epidemic
COVID-19 disease - Temporal analyses of complete blood count parameters over course of illness, and relationship to patient demographics and management outcomes in survivors and non-survivors: a longitudinal descriptive cohort study
Background. Detailed temporal analyses of complete (full) blood count (CBC) parameters, their evolution and relationship to patient age, gender, co-morbidities and management outcomes in survivors and non-survivors with COVID-19 disease, could identify prognostic clinical biomarkers.
Methods. From 29 January 2020 until 28 March 2020, we performed a longitudinal cohort study of COVID-19 inpatients at the Italian National Institute for Infectious Diseases, Rome, Italy. 9 CBC parameters were studied as continuous variables [neutrophils, lymphocytes, monocytes, platelets, mean platelet volume, red blood cell count, haemoglobin concentration, mean red blood cell volume and red blood cell distribution width (RDW %)]. Model-based punctual estimates, as average of all patients' values, and differences between survivors and non-survivors, overall, and by co-morbidities, at specific times after symptoms, with relative 95% CI and P-values, were obtained by marginal prediction and ANOVA- style joint tests. All analyses were carried out by STATA 15 statistical package.
Main findings. 379 COVID-19 patients [273 (72% were male; mean age was 61.67 (SD 15.60)] were enrolled and 1,805 measures per parameter were analysed. Neutrophils' counts were on average significantly higher in non-survivors than in survivors (P<0.001) and lymphocytes were on average higher in survivors (P<0.001). These differences were time dependent. Average platelets' counts (P<0.001) and median platelets' volume (P<0.001) were significantly different in survivors and non-survivors. The differences were time dependent and consistent with acute inflammation followed either by recovery or by death. Anaemia with anisocytosis was observed in the later phase of COVID-19 disease in non-survivors only. Mortality was significantly higher in patients with diabetes (OR = 3.28; 95%CI 1.51-7.13; p = 0.005), obesity (OR = 3.89; 95%CI 1.51-10.04; p = 0.010), chronic renal failure (OR = 9.23; 95%CI 3.49-24.36; p = 0.001), COPD (OR = 2.47; 95% IC 1.13-5.43; p = 0.033), cardiovascular diseases (OR = 4.46; 95%CI 2.25-8.86; p = 0.001), and those >60 years (OR = 4.21; 95%CI 1.82-9.77; p = 0.001). Age (OR = 2.59; 95%CI 1.04-6.45; p = 0.042), obesity (OR = 5.13; 95%CI 1.81-14.50; p = 0.002), renal chronic failure (OR = 5.20; 95%CI 1.80-14.97; p = 0.002) and cardiovascular diseases (OR 2.79; 95%CI 1.29-6.03; p = 0.009) were independently associated with poor clinical outcome at 30 days after symptoms' onset.
Interpretation. Increased neutrophil counts, reduced lymphocyte counts, increased median platelet volume and anaemia with anisocytosis, are poor prognostic indicators for COVID19, after adjusting for the confounding effect of obesity, chronic renal failure, COPD, cardiovascular diseases and age >60 years
Risk Factors for Hepatitis C Virus Transmission to Health Care Workers after Occupational Exposure: A European Case-Control Study
Background. Additional studies are required to identify risk factors for hepatitis C virus (HCV) transmission to health care workers after occupational exposure to HCV. Methods. We conducted a matched case-control study in 5 European countries from 1 January 1991 through 31 December 2002. Case patients were health care workers who experienced seroconversion after percutaneous or mucocutaneous exposure to HCV. Control subjects were HCV-exposed health care workers who did not experience seroconversion and were matched with case patients for center and period of exposure. Results. Sixty case patients and 204 control subjects were included in the study. All case patients were exposed to HCV-infected fluids through percutaneous injuries. The 37 case patients for whom information was available were exposed to viremic source patients. As risk factors for HCV infection, multivariate analysis identified needle placement in a source patient's vein or artery (odds ratio [OR], 100.1; 95% confidence interval [CI], 7.3-1365.7), deep injury (OR, 155.2; 95% CI, 7.1-3417.2), and sex of the health care worker (OR for male vs. female, 3.1; 95% CI, 1.0-10.0). Source patient HCV load was not introduced in the multivariate model. In unmatched univariate analysis, the risk of HCV transmission increased 11-fold for health care workers exposed to source patients with a viral load >6 log10 copies/mL (95% CI, 1.1-114.1), compared with exposures to source patients with a viral load ⩽4 log10 copies/mL. Conclusion. In this study, HCV occupational transmission was found to occur after percutaneous exposures. The risk of HCV transmission after percutaneous exposure increased with deep injuries and procedures involving hollow-bore needle placement in the source patient's vein or artery. These results highlight the need for widespread adoption of needlestick-prevention devices in health care settings, together with other preventive measure
