Aim To describe characteristics and outcome of mechanically ventilated patients admitted to three newly established intensive care units (ICU) in Bosnia-Herzegovina and Serbia for 2009 H1N1 influenza infection. Methods The retrospective observational study included all mechanically ventilated adult patients of three university-affiliated hospitals between November 1, 2009 and March 1 2010 who had 2009 H1N1 influenza infection confirmed by real-time reverse transcriptase-polymerase-chain-reaction (RT-PCR) from nasopharyngeal swab specimens and respiratory secretions. Results The study included 50 patients, 31 male (62%), aged 43 ± 13 years. Median time from hospital to ICU admission was 1 day (range 1-2). Sixteen patients (30%) presented with one or more chronic medical condition: 8 (16%) with chronic lung disease, 5 (10%) with chronic heart failure, and 3 (6%) with diabetes mellitus. Thirty-two (64%) were obese. Forty-eight patients (96%) experienced acute respiratory distress syndrome (ARDS), 28 (56%) septic shock, and 27 (54%) multiorgan failure. Forty-five patients (90%) were intubated and mechanically ventilated, 5 received non-invasive mechanical ventilation, 7 (14%) high-frequency oscillatory ventilation, and 7 (14%) renal replacement therapy. The median duration of mechanical ventilation was 7 (4-14) days. Hospital mortality was 52%.

This study represents Mycoplasma species isolated from the respiratory tract of cattle in Bosnia and Herzegovina between 2002 and 2010. A total of 328 nasal swabs and 59 lung samples were submitted for isolation of mycoplasmas. Mycoplasmas were isolated from 27 samples (6.9%). M. bovis was recovered from eight nasal swabs and two lungs, while M. bovirhinis (n=4) and Acholeplasma sp. (n=1) were detected only in nasal swabs. Twelve mycoplasma isolates were unidentified (44.4%).

Uvod. Destruktivnost u agresivnom ponasanju se interpretira multikauzalno,a psihijatrijski uzroci su bioloske, socijalne i psihopatoloske prirode. Cilj jeispitivanje unistavanja života u formi suicida i homicida u Bosni i Hercegoviniu periodu od 01. 01. 2001. do 31. 12. 2010.Metode. Studija ima multicentricnu, retrospektivnu formu. Mjerni instrumentisu bili: lista opstih podataka, Hamiltonova skala (HAMD), profil indeksemocija (P.I.E-Plutchik R.) i postmortem SSIPA-intervju sa deskriptivnom imultivarijantnom statistickom analizom.Rezultati. Multivarijantna regresiona analiza je pokazala da su sljedecevarijable znacajno povezane sa suicidom: starost [OR= 0,810 (95%), CI=0,770 - 1,100, P=0,003]; migracije [OR=0,830 (95%), CI = 0,825 -1,125, P=0,001];depresija [OR=1,150 (95%); CI=0,790-0,990, P=0,001] i destruktivnost na P. I.E. testu. Sa homicidom su znacajno povezane sljedece varijable: edukacijaoca [OR=0,910 (95%), CI=0,620-1,100, P<0,001], život u blizini mjesta zlocina[OR=0,630 (95%), CI=0,970-0,910, P<0,001]; predgrađu [OR=0,850 (95%),CI = 0,930 -1,25, P<0,001]; destruktivnost [OR= 0,670 (95%), CI= 990–1,210,P<0,001]; inkorporacija, orijentacija i bias na P. I. E testu.Zakljucak. Studija je potvrdila porast destruktivnosti kod agresivnog ponasanjau suicidu i homicidu u Bosni i Hercegovini, sto ima medikolegalni znacaj.Studija ukazuje i na socijalne i psihopatoloske odlike pocinilaca agresivnostiu Bosni i Hercegovini.Kljucne rijeci: destruktivnost,

Orthogonal frequency division multiplexing (OFDM) has been adopted for several wireless network standards due to its robustness against multipath fading. Main drawback of OFDM is its high peak-to-average power ratio (PAPR) that causes a signal degradation in a peak-limiting (e.g., clipping) channel leading to a higher bit error rate (BER). At the receiver end, the effect of peak limitation can be removed to some extent to improve the system performance. In this paper, a joint iterative channel estimation/equalization and clipping noise reduction technique based on minimum mean square error (MMSE) criterion is presented. The equalization weight that minimizes the mean square error (MSE) between the signal after channel equalization and feedback signal after clipping noise reduction is derived assuming imperfect channel state information (CSI). The MSE performance of the proposed technique is theoretically evaluated. It is shown that the BER performance of OFDM with proposed technique can be significantly improved in a peak-limited and doubly-selective (i.e., time- and frequency-selective) fading channel.
