A 29-year old male with recurrent respiratory and skin infections, anaemia and neutropaenia during childhood required immunoglobulin replacement for antibody deficiency from age 16. He remained relatively well until age 28 when he presented with a two-week history of fatigue, sore throat, fever and productive cough. He was found to have EBV viraemia and splenomegaly and a diagnosis of EBV-driven lymphoproliferative disease was made following bone marrow trephine. Family history was notable with three siblings a healthy sister and two brothers with anaemia and neutropaenia; one who succumbed to septicaemia secondary to neutropaenic enterocolitis age 5 and another who developed intestinal vasculitis and antibody deficiency and had a successful haemopoetic stem cell transplant. The proband's DNA underwent targeted sequencing of 279 genes associated with immunodeficiency (GRID panel). The best candidates were two ADA2 variants, p.Arg169Gln (R169Q) and p.Asn370Lys (N370K). Sanger sequencing and co-segregation of variants in the parents, unaffected sister and all three affected brothers was fully consistent with compound heterozygous inheritance. Subsequent whole genome sequencing of the proband identified no other potential causal variants. ADA2 activity was consistent with a diagnosis of ADA2 deficiency in affected family members. This is the first description of EBV-driven lymphoproliferative disease in ADA2 deficiency. ADA2 deficiency may cause susceptibility to severe EBV-induced disease and we would recommend that EBV status and viral load is monitored in patients with this diagnosis and allogeneic SCT is considered at an early stage for patients whose ADA2 deficiency is associated with significant complications. OBJECTIVES Somatic chromosomal rearrangements resulting in ALK fusion oncogenes are observed in 3-7 % of lung adenocarcinomas. ALK tyrosine kinase inhibitors (ALKi) induce initially response, however, various resistance mechanisms limit their efficacy. Novel therapeutic approaches are of utmost importance to tailor these targeted therapies. MATERIALS AND METHODS A synchronous ALK-rearranged and mutated lung cancer cell line pair was established from malignant pleural effusion (PF240-PE) and carcinosis (PF240-PC) at time of ALKi resistance. Immunohistochemistry, FISH and sequencing were performed in pre- and post-treatment tumors and in both cell lines. Differentiation markers were measured by immunoblot. Viability was tested following treatment with ALKi and/or a pan-HDAC inhibitor. Additionally, a novel treatment-naïve ALK-rearranged cell line served as control. In vivo tumorigenicity was evaluated in subcutaneous xenografts. RESULTS Two distinct resistance mutations were identified in different carcinosis tissues at time of resistance, the previously described resistance mutation L1152R and the hitherto uncharacterized E1161K. Strikingly, PF240-PC cells carried E1161K and PF240-PE cells harbored L1152R. Immunohistochemistry and immunoblot identified epithelial-to-mesenchymal transition markers upregulated following ALKi resistance development both in carcinosis tissues and cell lines. While both lines grew as xenografts, they differed in morphology, migration, in vivo growth and sensitivity to ALKi in vitro. Strikingly, the combination of ALKi with SAHA yielded strong synergism. CONCLUSION Using a patient-derived ALKi resistant lung cancer model we demonstrated the synergism of HDAC and ALK inhibition. Furthermore, our findings provide strong evidence for intratumoral heterogeneity under targeted therapy and highlight the importance of site-specific mutational analysis. BACKGROUND On the April 25, 2015, a 7.8 magnitude earthquake struck Nepal. Soon-after, the Israel Defense Force (IDF) dispatched a tertiary field-hospital to Kathmandu. The field-hospital was equipped with a clinical laboratory with microbiology capabilities. Limited data exists regarding the spectrum of bacteria isolated from earthquake casualties. We aimed to identify the spectrum of bacteria and their mechanisms of resistance in-order to allow preparedness of antibiotic treatment protocols for future disaster scenarios. METHODS - The field-laboratory phenotypically processed cultures from sterile and non-sterile sites as needed clinically. Later-on, the isolates were brought to Israel for quality control, definite identification and molecular characterization including mechanisms of resistance. RESULTS A total of 82 clinical pathogens were isolated from 56 patients; 68% of them were Gram negative bacilli. The most common isolates were Enterobacteriaceae (55%) -36% carried bla-NDM and 33% produced Extended-spectrum beta-lactamase (ESBL), mostly blaCTX-M-15. Enterococcus spp were the main Gram positive bacteria isolated (22 isolates), yet, none were vancomycin resistant. The overall level of resistance was 27% MDR and 23% extensively drug resistant (XDR) bacteria. CONCLUSIONS - Gram negative bacteria were the predominant organism cultured from the casualties, of them 77% were MDR or XDR. NDM was the most common resistance mechanism. The Antibiotic inventory of a field-hospital should be set to cover a wide and unexpected spectrum of bacteria, including resistant organisms. This report adds important information to the scarce reports of bacterial resistance in Nepal. BACKGROUND Travelers' diarrhea (TD) is the most common illness experienced by travelers to developing regions of the world and may be caused by bacterial, parasitic or viral pathogens. The available diagnostic tests include stool microscopy for protozoal infections, culture-dependent methods for bacterial infections and molecular methods for bacterial, parasitic and viral infections. METHOD We retrospectively evaluated demographic, clinical and microbiological data of patients presenting with TD at our travel clinic between 2009 and 2017. RESULTS Among 676 patients with TD included in our study, at least one etiologic agent was found in only 21% (n = 145) of cases. In total, 195 enteropathogens were detected of which 110 were bacteria, 70 protozoa and 15 helminths. Bacterial infections were significantly more common when symptoms were present less than 14 days and travel duration did not exceed 30 days. Protozoa and helminths were predominantly detected in patients with longer lasting complaints. After stool culture was replaced by a multiplex-PCR gastrointestinal pathogen panel (GPP) at our center, significantly more intestinal bacterial pathogens were detected. CONCLUSIONS Our results support an individualized approach in the diagnostic workup of patients with TD taking host and travel characteristics into account to avoid unnecessary diagnostic testing. Molecular culture-independent diagnostic stool tests provide better coverage of the variety of etiological agents than traditional stool culture and have the benefit of rapid detection. However, the high sensitivity bears challenges differentiating colonization from infection. Genetic fusion of a therapeutic protein to albumin can improve its stability and pharmacokinetics, but it usually leads to considerably reduced bioactivity and poor tumor penetration due to increased steric hindrance, resulting in limited antitumor efficacy. Herein we report head-to-tail macrocyclization of albumin-binding domain fused interferon alpha (IFN-ABD) to form a cyclic fusion protein (c-IFN-ABD) with well-retained albumin-binding affinity. Notably, c-IFN-ABD showed not only greater thermal and enzymatic stability and thus antiproliferative activity than IFN-ABD and IFN due to the macrocyclization, but also exhibited considerably better pharmacokinetics than IFN and cyclic IFN owing to the albumin-binding affinity. More importantly, c-IFN-ABD showed deeper tumor penetration, greater tumor retention, and thus higher antitumor efficiency than all the controls without significant systemic side effects in mice bearing melanoma. These results implicate that head-to-tail macrocyclization of ABD fused therapeutic proteins is an enabling strategy for the design of highly potent protein therapeutics for tumor therapy. Tea plant is an important economic crop, which produces the world's oldest and widely consumed tea beverages. We here present a high-quality reference genome of the tea plant (Camellia sinensis var. sinensis) consisting of 15 pseudo-chromosomes, 70.38% of which are LTR retrotransposons. We show the evidence that LTR-RTs play critical roles in the genome size expansion and transcriptional diversification of tea plant genes through preferential gene insertions in promoter regions and introns. this website Genes, particularly those for terpene biosynthesis, associated with tea aroma and stress resistance are significantly amplified forming gene clusters through recent tandem duplications in the tea plant genome. Phylogenetic analyses of the sequences of 81 tea plant accessions of diverse origins revealed three well-differentiated tea plant populations, supporting the proposition for the southwest origin of the cultivated tea plants in China and its later spreading to western Asian through introduction. Domestication and modern breeding left significant signatures on hundreds of genes in the tea plant genome, particularly those associated with tea quality and stress resistance. The genomic sequences of the reported reference and resequenced tea plant accessions provided valuable resources for future functional genomic and breeding research of tea plants and understanding the genome evolution of flowering plants. The transition from open shoulder surgery to arthroscopic shoulder surgery represents a classic paradigm shift. In order for that paradigm shift to have occurred, the early pioneers in this discipline had to assume several burdens of their new craft the burden of "arthroscopic identification"; the burden of developing the language of arthroscopy; the burden of disseminating arthroscopic knowledge; the burden of developing safe arthroscopic instruments and implants; and the burden of proving biomechanical and structural equivalency between arthroscopic and open constructs. Embracing these obligations, they were able to produce the paradigm shift to arthroscopic shoulder surgery through a spirited mix of depth, breadth, and tenacity, defying long odds and conventional wisdom while creating a major breakthrough in shoulder surgery. The American physicist and philosopher Thomas Kuhn coined the term paradigm shift in 1962 in his classic book The Structure of Scientific Revolutions (Ref 1). He defined paradigm shift as a fundamental change in the basic concepts and practices of a discipline. Based on that definition, I believe that the transition from open shoulder surgery to arthroscopic shoulder surgery represents a classic paradigm shift. PURPOSE To assess whether labral size is predictive of labral repair failure or demonstrates association with patient outcomes post-hip arthroscopy. METHODS A retrospective chart review was performed for patients undergoing arthroscopic hip labral repair. Labral size was measured in 4 quadrants with an arthroscopic probe. The average size across torn labral segments was assessed for failure as determined by change in PROs, the rate at which subjects achieved MCID and PASS, and need for additional surgery. Outcomes were evaluated for any continuous correlation as well as significant differences between classes of labral sizes derived from upper and lower quartile and decile ranges against the middle 50%. Included hips were those from patients between the ages 18 and 55 with 2-year postoperative follow up and lateral center edge angles (LCEA) between 25-40°. RESULTS The study included 571 hips. Labral width did not show significant difference between those requiring revision versus those not requiring revision (p= .
