    Abstract This study investigated how early growth was affected in various chicken genotypes, which were fed ad libitum or restricted and with or without poultry red mite (PRM) infestation. Atak-S (AS), New Hampshire Red (NHR), and Light Sussex (LS) genotypes were used in the study. In total, 120 chicks were used from each genotype. Four groups were formed: feed-restricted (FR) and infested with parasite (P + ), FR only, fed ad libitum and P + , and fed ad libitum only. Feed restriction was applied as 20 % of the feed consumption of the group fed ad libitum the day before for each genotype. The study was conducted between 2 to 12 weeks of age. Weekly live weights and feed consumption were recorded, and the feed conversion ratio was calculated. Traps were placed in cages to count parasites. Regarding the live weight, NHR tolerated the PRM infestation in the ad libitum feed conditions better than other genotypes. While the infested NHR and AS birds had lower live weights than the non-infested ones under FR conditions, there was no difference between infested and non-infested birds of NHR and AS genotypes when they fed ad libitum. The feed consumption of infested AS and NHR birds was higher than that of non-infested counterparts when fed ad libitum. By contrast, the LS chicks consumed less food in the infested environment. In conclusion, the genotypes responded differently to PRM infestation in different feeding environments.

    Abstract Purpose: To investigate the epidemiology of candiduria in critically-ill patients with solid/hematological malignancies and to assess its predictive factors and prognostic value.
    Methods: All adult patients with confirmed solid/hematological malignancy admitted in the intensive care units (ICUs) for more than 48 h were retrospectively included. Urine cultures were sampled on admission and then whenever signs of sepsis were identified. Two groups were compared: (candiduria (+)) and (candiduria (-)).
    Results: One-hundred-seventy-three patients were included. Solid cancer was the underlying oncological disease for 147 patients (85%) while 26 patients (15%) had hematological malignancies. Twenty-nine patients (16.8%) were diagnosed with candiduria, and 31 urinary samples grew Candida spp. Candida spp represented 55.8% of the total urinary isolates. Fourteen isolates (45.2%) of Candida albicans were identified. Among the 17 non-albicans isolates, Candida tropicalis was the most predominant (41.9%). Six patients (3.5%) had candidemia with no significant difference between candiduria(+) and candiduria(-) groups (respectively, 6.9% and 2.8%; p = 0.264). In multivariate analysis, previous exposure to quinolones (OR = 3.8, CI95% [1.4-8.3]; p = 0.008), mechanical ventilation (OR = 4.1, CI95% [1.1-14.7]; p = 0.034) and renal replacement therapy (OR = 3.5, 95%CI [1.2-9.7]; p = 0.017) were identified as independent factors predicting candiduria. Candiduria was associated with significantly higher ICU-mortality after adjusting for SAPSII score on admission (OR = 2.9 CI95% [1.3-6.8]; p = 0.009).
    Conclusion: Candiduria is common in cancer critically-ill patients. We reported an increased rate of non-albicans species, over albicans species. Patients with candiduria had higher ICU mortality, probably related to higher frailty and clinical severity.

    Abstract Background: Up to 30% of patients with acute pericarditis develop recurrent pericarditis. Acute pericarditis may be a manifestation of an underlying systemic autoimmune disease. Therefore, we evaluated the characteristics of patients with acute pericarditis according to antinuclear antibodies (ANA) positivity/negativity.
    Methods: Participants with acute pericarditis and negative ANA (n=29), recurrent pericarditis with positive ANA (n=30) and healthy controls (n=11) were examined. The groups were compared using serum parameters (ANA, C-reactive protein, leucocyte count, erythrocyte sedimentation rate, total antioxidant status, nitric oxide (NO), and oxidative stress index (OSI)) and imaging techniques (electrocardiogram, echocardiography, cardiovascular magnetic resonance, and venous Doppler ultrasound).
    Results: In females, acute pericarditis associated with ANA occurred more frequently (p<0.001). ANApositive acute pericarditis had significantly lower NO and OSI (p<0.05 and p<0.001, respectively) and pericardial inflammation on magnetic resonance. We found a pulmonary embolism in one patient with positive ANA. Slow venous flow (SVF) occurred more often in acute pericarditis associated with ANA than in the ANA-negative group on venous ultrasound (p<0.05). The prevalence of positive ANAs was 1.6 times higher among SVF patients than in controls.
    Conclusion: This study suggests that acute pericarditis associated with ANA is more common in middle- aged females. SVF and lower oxidative stress tests were more common in patients with ANAassociated acute pericarditis. Acute pericarditis associated with ANA could be considered as a hypercoagulable state. Therefore, all newly diagnosed pericarditis patients (especially females) should be checked for ANA positivity. Awareness of this coexistence should be promptly addressed to establish management strategies.

    Abstract Infectious diseases have caused great catastrophes in human history, as in the example of the plague, which wiped out half of the population in Europe in the 14th century. Ebola virus and H7N9 avian influenza virus are 2 lethal pathogens that we have encountered in the second decade of the 21st century. Ebola infection is currently being seen in West Africa, and H7N9 avian flu appears to have settled in Southeast Asia. This article focuses on the current situation and the future prospects of these potential infectious threats to mankind.
