Background: Surgical mortality data are collected routinely in high-income countries, yet virtually no low-or middle-income countries have outcome surveillance in place. The aim was prospectively to collect worldwide mortality data following emergency abdominal surgery, comparing findings across countries with a low, middle or high Human Development Index (HDI).Methods: This was a prospective, multicentre, cohort study. Self-selected hospitals performing emergency surgery submitted prespecified data for consecutive patients from at least one 2-week interval during July to December 2014. Postoperative mortality was analysed by hierarchical multivariable logistic regression.
Background: Residual feed intake (RFI) is the difference between actual and predicted feed intake and an important factor determining feed efficiency (FE). Recently, 170 candidate genes were associated with RFI, but no expression quantitative trait loci (eQTL) mapping has hitherto been performed on FE related genes in dairy cows. In this study, an integrative systems genetics approach was applied to map eQTLs in Holstein and Jersey cows fed two different diets to improve identification of candidate genes for FE. Methods: Liver RNA-seq transcriptomics data from nine Holstein and ten Jersey cows that had been fed control (C) or high concentrate (HC) diets were integrated with genomic data (from 777k BovineHD Illumina BeadChip) by using the Matrix eQTL R package. A total of 170 previously identified candidate genes for FE (89 differentially expressed genes (DEGs) between high and low RFI groups and 81 hub genes (HG) in a group of co-expressed genes) were used in the data integration analysis. Results: From the 241,542 SNPs used in the analysis, we identified 20 significant (FDR < 0.05) local-eQTLs targeting seven candidate genes and 16 significant (FDR < 0.05) local-eQTLs targeting five candidate genes related to RFI for the C and HC diet group analysis, respectively, in a breed-specific way. Conclusions: Interestingly, Holstein and Jersey cows appear to rely on different strategies (lipid and cholesterol metabolism versus immune and inflammatory function) to achieve low RFI. The eQTLs overlapped with QTLs previously associated with FE trait (e.g. dry matter intake, longevity, body weight gain and net merit). The eQTLs and biological pathways identified in this study improve our understanding of the complex biological and genetic mechanisms that determine FE traits in dairy cattle. The identified eQTLs/genetic variants can potentially be used in new genomic selection methods that include biological/functional information on SNPs.
Introduction: Many cancer patients in general require long term venous access such as chemoport for chemotherapy, as well as infusion of fluids and blood taking. However, chemoport insertions carry complications such as infection, blockage, pneumothorax and malposition. We received feedbacks regarding complications endured by patients after chemoport insertion from the respective teams managing the patients in our hospital. In view of that, we conducted a retrospective audit on the chemoport insertions which we have done. Materials and Methods: We conducted a retrospective audit on the chemoport insertions which was planned for open method insertion through cephalic vein performed over the last 4 years from 2014 to 2017. Results: A total of 102 chemoports were inserted. Majority of patient’s ages are 50-59 years old. 88 (86%) of the cases were done via open method whereas another 14 cases were converted to percutaneous route. Majority of patients (55%) of the patients have breast carcinoma followed by colorectal (28%), haematological (12%) and gynaecological malignancies (5%). Complications occurred in 10 patients (rate at 9.8%). Most common complications were catheter related infection (5 cases) followed by wound infection (3 cases) and malposition (2 cases). Malposition was detected on post-operative chest radiograph and revision was done. All catheter related infection occurred in patients with haematological malignancies. Our complication rate of 9.8% is lower than the accepted complication rate of 15-25% worldwide. Conclusion: Chemoport provides a robust vascular access especially for the purpose of chemotherapy infusion. We showed with adequate training and privileging, it can be performed with very limited complications.
Liver abscess can present in various manners and in some cases causes delays and misdiagnoses. We are reporting 2 cases of rare presentation of liver abscess. The first case is a 64-year-old gentleman presented with right hypochondriac pain since August 2017 and diagnosed to have liver abscess. He was treated with antibiotics and serial imaging for reassessment. However, he presented again this year with right sided anterior abdominal wall swelling. Abdominal computed tomography (CT) showed anterior abdominal wall collection with extension into right internal and external oblique muscles with communication with liver collection at segment VII. An open incision and drainage was performed with drain inserted over the anterior abdominal wall collection. He was then referred to hepatobiliary center for further management. Second case is a 30-year-old gentleman underlying Beta thalassemia major- post splenectomy with Klebsiella pneumonia bacteremia noted to have left multiseptated collection with posterobasal consolidation and left parapneumonic effusion which was initially misdiagnosed as splenic abscess. However, with further imaging was confirmed to be a left liver abscess with focal discontinuity in left hemidiaphragm, which communicates between liver abscess and enlarging left lower loculated pleural effusion. Radiological guided pigtail catheter was inserted and serial imaging showed collection decreasing in size. Extra-abdominal manifestation of a liver abscess is a rare clinical entity and is not well documented. The advent of ultrasound and CT scan, there has been improvement in the rate of early diagnosis even with these uncommon presentations. Percutaneous drainage with antimicrobial therapy remains gold standard for a non-ruptured abscess. Surgical intervention should be considered for large, complex, multiseptated abscesses or in whom percutaneous drainage has failed.
