RESUMO

Poultry farming has developed into one of Algeria's most productive industrial farming because of the growing demand for sources of protein among Algerian society. Laying hen feed consists mainly of cereals, which can be contaminated with molds and subsequently with their secondary metabolites known as mycotoxins. These later can pose a serious danger to the production and quality of eggs in the commercial layer industry. This work focuses on the detection of emerging mycotoxins, mainly enniatins (ENNs) and beauvericin (BEA), in poultry feed and eggs from different locations in Algeria. Two different QuEChERS-based extractions were established to extract ENNs and BEA from chicken feed and eggs. The determination of mycotoxin occurrence was achieved by a UHPLC-MS/MS method using 0.1% (v/v) formic acid in water and MeOH as mobile phase, an ESI interface operating in positive mode, and a triple quadrupole mass spectrometer operating in MRM for the detection. Matrix-matched calibration curves were carried out for both matrices, obtaining good linearity (R2 > 0.99). The method performance was assessed in terms of extraction recovery (from 87 to 107%), matrix effect (from - 47 to - 86%), precision (RSD < 15%), and limits of quantitation (≤ 1.1 µg/kg for feed and ≤ 0.8 µg/kg for eggs). The analysis of 10 chicken feed samples and 35 egg samples composed of a 10-egg pool each showed that ENN B1 was the most common mycotoxin (i.e., found in 9 feed samples) with contamination levels ranging from 3.6 to 41.5 µg/kg, while BEA was detected only in one feed sample (12 µg/kg). However, eggs were not found to be contaminated with any mycotoxin at the detection limit levels. Our findings indicate that the searched mycotoxins are present in traces in feed and absent in eggs. This can be explained by the application of a mycotoxin binder. However, this does not put a stop on the conduction of additional research and ultimately setting regulations to prevent the occurrence of emerging mycotoxins.

RESUMO

BACKGROUND: Evidence surrounding P2Y12 platelet reactivity units (PRU) impact on bleeding outcomes in patients undergoing coronary artery bypass is varied. This study sought to assess whether on-pump CABG procedures result in increased bleeding in patients with high compared to low PRUs. METHODS: This retrospective cohort study compared those with a PRU level ≤237 (low PRU group) to >237 (high PRU group). The primary outcome assessed massive or severe bleeding in accordance with universal definition of perioperative bleeding criteria. Secondary outcomes assessed mortality, length of stay and relevant bleeding related outcomes (e.g., rates of moderate or lower classifications of bleeding, chest tube output, blood product receipt). RESULTS: A total of 69 patients were included, 47 in the low and 22 in the high PRU groups. Patients were a median (IQR) 66 (62-74) years and 84.1% (N.=58) were male. Most patients received clopidogrel prior to procedure (39 [83%] in low and 18 [81.8%] in high PRU group; P=1.0000). The rate of the primary outcome was 14.9% (N.=7) in patients with a low PRU and 18.2% (N.=4) in patients with a high PRU; P=0.7345. The rate of moderate bleeding was 59.6% (N.=28) in the low and 27.3% (N.=6) in the high PRU group (P=0.0124). Packed red blood cells (PRBCs) were administered to more patients in the low (23 [48.9%]) than the high PRU group (2 [22.7%]; P=0.0388). There were no differences in other blood product requirement, chest tube output, factor products administered, mortality, or length of stay. CONCLUSIONS: This study determined that low preoperative P2Y12 PRU levels may influence moderate bleeding in patients undergoing cardiac surgery, but not massive or severe bleeding.

RESUMO

Cardiovascular disease is one of the leading causes of death around the world with various efforts being made to reduce risk in patients through preventive measures. One major method for prevention has been managing cholesterol, particularly low-density lipoprotein to decrease atherosclerotic plaque burden, potentially decreasing future cardiac complications. Statins have been the gold standard therapy for hypercholesterolemia treatment due to their ease of dosing, limited drug interactions, and favorable safety profile. Unfortunately, statin therapy alone is not always effective enough to adequately control a patient's elevated lipid levels and combination therapy may be warranted. Ezetimibe is commonly added to regimens to help augment cholesterol lowering by inhibiting the absorption of cholesterol. The recent approval of a combination tablet of high-intensity rosuvastatin and ezetimibe has introduced a potentially more beneficial option for cholesterol management in addition to the only available combination of moderate intensity simvastatin and ezetimibe. We aimed to identify potential beneficial effects of ezetimibe by comparing its use in combination with high-intensity rosuvastatin compared to a statin therapy alone or in combination with moderate intensity simvastatin through a literature review. The current evidence indicated that combination therapy outperformed statin monotherapy in reduction of low-density lipoprotein cholesterol and patients were more likely to achieve their target low-density lipoprotein cholesterol goal level. This suggests rosuvastatin/ezetimibe combination holds a potential place in therapy for patients requiring a more aggressive reduction in cholesterol to help prevent atherosclerotic disease.

RESUMO

This study consists of the evaluation of the anticoccidial effect of Artemisia herba-alba Asso during experimental coccidial infection. Four groups of 30 broiler chickens were formed: the negative control (G1), the positive control (G2), the infected Monensin-treated group (G3), and the infected Artemisia-treated group (G4). Each infected bird received orally 105 sporulated oocysts of Eimeria tenella. No mortality was recorded in both G1 and G4. Haematocrit levels showed great variations from the 7th day post-infection, especially in G2 (20.87% ± 5.77). By day 10 P-I, haematocrit recovery was rapid particularly in G4 (28.07% ± 1.50). Haemoglobin concentration also decreased significantly (p < 0.05) in all infected groups by the 7th day P-I. The reduction was very marked, but not statistically significant, in G2 (6.47 g/dL ± 1.67) against (10.53 g/dL ± 0.25) in G1. It was less marked in G4 (8.05 g/dL ± 1.56). Results show the protective effect of A. herba-alba Asso by improving the lesion score and the haematological parameters affected during coccidian infection.

RESUMO

AIM: The objective of this study is to examine the alterations in the levels of expression of serum lncRNA-TSIX, TP53INP2 mRNA, miRNA-1283 in spinal cord injured (SCI) patients versus healthy control. METHOD: The expression of the selected RNAs in the sera was determined in 23 patients suffering from acute spinal cord injury, 41 individuals with chronic spinal cord injury, and 36 healthy control using real-time reverse-transcription polymerase chain reaction method. RESULTS: The results showed that lncRNA-TSIX and the TP53INP2 mRNA expression levels in SCI patients was overexpressed in comparison to the control group alongside with a significant downregulation of miR-1283. Statistically,there was a highly significant positive correlation between lnc-RNA-TRIX and TP53INP2 mRNA with inverse correlation between miRNA-1283 and lnc-RNA-TRIX based on fold changes. CONCLUSION: Up-regulation of lncRNA-TSIX, TP53INP2 mRNA with downregulation of miRNA-1283 might be closely associated with progression of SCI.

RESUMO

BACKGROUND: There are many challenges facing Syrian refugee children with heart disease. In this report, we present the spectrum, management, and outcome of heart disease in Syrian refugee children over six-year period, highlighting challenges in management and availability of funding. METHODS: Data on Syrian refugee children with heart disease diagnosed between 2012 and 2017 were collected. Patients were followed until January 2019. Data reported included age, diagnosis, recommended treatment, types of procedures done, mortality, cost, financial sources for procedures, and outcome. RESULTS: 415 Syrian refugee children were diagnosed with heart disease at our institution. Median age was 1·9 years (0·4-6·05) years. Children were either born in Syria and fled to Jordan with their families (224, 54%), or born in Jordan to refugee parents (191, 46%). Follow-up was established for 335 patients (81%). Of 196 patients needing surgery, 130 (72%) underwent Surgery, and of 97 patients needing interventional catheterization, 95 underwent the procedure. Waiting time was 222(± 272) days for surgery and 67(± 75) days for catheterizations. Overall mortality was 17% (56 patients), of which 28 died while waiting for surgery. Cost of surgical and interventional catheterization procedures was $7820 (± $4790) and $2920 (± $2140), respectively. Funding was obtained mainly from non-government organizations, private donors, and United Nations fund. CONCLUSION: Despite local and international efforts to manage Syrian refugee children with heart disease, there is significant shortage in providing treatment resulting in delays and mortality. More organized efforts are needed to help with this ongoing crisis.
