2Cholestatic liver diseases:An era of emerging therapies显示文摘Recently the field of cholestasis has expanded enormously reflecting an improved understanding of the molecular mechanisms underlying bile secretion and its perturbation in chronic cholestatic disease. Novel anti-cholestatic therapeutic options have been developed for patients not favorably responding to ursodeoxycholic acid (UDCA), the current standard treatment for cholestatic liver disease. Important novel treatment targets now also include nuclear receptors involved in bile acid (BA) homoeostasis like farnesoid X receptor and G proteincoupled receptors e.g., the G-protein-coupled BA receptor “transmembrane G coupled receptor 5”. Fibroblast growth factor-19 and enterohepatic BA transporters also deserve attention as additional drug targets as does the potential treatment agent norUDCA. In this review, we discuss recent and future promising therapeutic agents and their potential molecular mechanisms in cholestatic liver disorders.Hrishikesh Samant Wuttiporn Manatsathit David Dies Hosein Shokouh-Amiri Gazi Zibari Moheb Boktor Jonathan Steve Alexander 2019World Journal of Clinical Cases2019,7,13:6
3Clinical outcomes following salvage Gamma Knife radiosurgery for recurrent glioblastoma显示文摘Glioblastoma multiforme(GBM) is the most common malignant primary brain tumor with a survival prognosis of 14-16 mo for the highest functioning patients. Despite aggressive, multimodal upfront therapies, the majority of GBMs will recur in approximately six months. Salvage therapy options for recurrent GBM(r GBM) are an area of intense research. This study compares recent survival and quality of life outcomes following Gamma Knife radiosurgery(GKRS) salvage therapy. Following a Pub Med search for studies usingGKRS as salvage therapy for malignant gliomas, nine articles from 2005 to July 2013 were identified which evaluated rG BM treatment. In this review, we compare overall survival following diagnosis, overall survival following salvage treatment, progression-free survival, time to recurrence, local tumor control, and adverse radiation effects. This report discusses results for rG BM patient populations alone, not for mixed populations with other tumor histology grades. All nine studies reported median overall survival rates(from diagnosis, range:16.7-33.2 mo; from salvage, range:9-17.9 mo). Three studies identified median progression-free survival(range:4.6-14.9 mo). Two showed median time to recurrence of GBM. Two discussed local tumor control. Six studies reported adverse radiation effects(range:0%-46% of patients). The greatest survival advantages were seen in patients who received GKRS salvage along with other treatments, like resection or bevacizumab, suggesting that appropriately tailored multimodal therapy should be considered with each rG BM patient. However, there needs to be a randomized clinical trial to test GKRS for rG BM before the possibility of selection bias can be dismissed.Erik W Larson Halloran E Peterson Wayne T Lamoreaux Alexander R MacKay Robert K Fairbanks Jason A Call Jonathan D Carlson Benjamin C Ling John J Demakas Barton S Cooke Christopher M Lee 2014World Journal of Clinical Oncology2014,5,2:5
4Evaluation of a point of care ultrasound curriculum for Indonesian physicians taught by fi rst-year medical students显示文摘BACKGROUND: The purpose of this study was to assess the short-term efficacy of a 4-week ultrasound curriculum taught by American first-year medical students to general practitioners working in public health care clinics, or puskesmas, in Bandung, Indonesia.METHODS: We performed a prospective, observational study of Indonesian health care practitioners from public clinics in Bandung, Indonesia. These practitioners were enrolled in a 4-week ultrasound training course taught by first-year American medical students. A total of six sessions were held comprising of 38 ultrasound milestones. A pre-course and post-course written exam and practical exam was taken by each participant.RESULTS: We enrolled 41 clinicians in the course. The average pre-course exam score was 35.2% with a 2.4% pass rate, whereas the average post-course exam score was 82.0% with a 92.7% pass rate. The average practical score at the completion of the course was 83.2%(SD=0.145) with 82.9% of the class passing(score above 75.0%).CONCLUSION: Our data suggests that first-year medical students can effectively teach ultrasound to physicians in Indonesia using a 4-week intensive ultrasound training course. Future studies are needed to determine the amount of training required for proficiency and to evaluate the physicians' perceptions of the student-instructors' depth of knowledge and skill in point of care ultrasound.Jonathan B.Lee Christina Tse Thomas Keown Michael Louthan Christopher Gabriel Alexander Anshus Bima Hasjim Katrina Lee Esther Kim Luke Yu Allen Yu Shadi Lahham Steven Bunch Maili Alvarado Abdulatif Gari John C.Fox 2017World Journal of Emergency Medicine2017,8,4:4
5Pregnancy and inflammatory bowel diseases: Current perspectives, risks and patient management显示文摘Inflammatory bowel diseases(IBD) are chronic idiopathic inflammatory conditions characterized by relapsing and remitting episodes of inflammation which can affect several different regions of the gastrointestinal tract, but also shows extra-intestinal manifestations. IBD is most frequently diagnosed during peak female reproductive years, with 25% of women with IBD conceiving after their diagnosis. While IBD therapy has improved dramatically with enhanced surveillance and more abundant and powerful treatment options, IBD disease can have important effects on pregnancy and presents several challenges for maintaining optimal outcomes for mothers with IBD and the developing fetus/neonate. Women with IBD, the medical team treating them(both gastroenterologists and obstetricians/gynecologists) must often make highly complicated choices regarding conception, pregnancy, and post-natal care(particularly breastfeeding) related to their choice of treatment options at different phases of pregnancy as well as post-partum. This current review discusses current concerns and recommendations for pregnancy duringIBD and is intended for gastroenterologists, general practitioners and IBD patients intending to become,(or already) pregnant, and their families. We have addressed patterns of IBD inheritance, effects of IBD on fertility and conception(in both men and women), the effects of IBD disease activity on maintenance of pregnancy and outcomes, risks of diagnostic procedures during pregnancy and potential risks and complications associated with different classes of IBD therapeutics. We also have evaluated the clinical experience using 'top-down' care with biologics, which is currently the standard care at our institution. Post-partum care and breastfeeding recommendations are also addressed.Pegah Hosseini-Carroll Monica Mutyala Abhishek Seth Shaheen Nageeb Demiana Soliman Moheb Boktor Ankur Sheth Jonathon Chapman James Morris Paul Jordan Kenneth Manas Felix Becker Jonathan Steven Alexander 2015World Journal of Gastrointestinal Pharmacology and Therapeutics2015,6,4:4

7Partial Shape Matching Without Point-Wise Correspondence显示文摘Partial similarity of shapes is a challenging problem arising in many important applications in computer vision,shape analysis,and graphics,e.g.when one has to deal with partial information and acquisition artifacts.The problem is especially hard when the underlying shapes are non-rigid and are given up to a deformation.Partial matching is usually approached by computing local descriptors on a pair of shapes and then establishing a point-wise non-bijective correspondence between the two,taking into account possibly different parts.In this paper,we introduce an alternative correspondence-less approach to matching fragments to an entire shape undergoing a non-rigid deformation.We use region-wise local descriptors and optimize over the integration domains on which the integral descriptors of the two parts match.The problem is regularized using the Mumford-Shah functional.We show an efficient discretization based on the Ambrosio-Tortorelli approximation generalized to triangular point clouds and meshes,and present experiments demonstrating the success of the proposed method.Jonathan Pokrass Alexander M.Bronstein Michael M.Bronstein 2013Numerical Mathematics(Theory,Methods and Applications)2013,6,1:3

11Comparison of ultrasound-measured properties of the common carotid artery to tobacco smoke exposure in a cohort of Indonesian patients显示文摘BACKGROUND: The purpose of this study was to use point-of-care ultrasound(POCUS) to investigate the relationship between tobacco smoke exposure and the characteristics of the common carotid artery(CCA). The effect of both primary and secondary smoking on CCA properties was evaluated.METHODS: We performed a prospective cross-sectional study across 20 primary care clinics in Bandung, West Java, Indonesia in July 2016. Point of care ultrasound was performed on a convenience sample of Indonesian patients presenting to clinic. The CCA wall stiffness and carotid intima-media thickness(CIMT) were measured during diastole and systole. These measurements were correlated with smoke exposure and cardiovascular disease.RESULTS: We enrolled 663 patients in the study, with 426 patients enrolled in the smoking category and 237 patients enrolled in the second-hand smoke category. There was an overall positive correlation with the measured lifestyle factors and the ultrasound-measured variables in the group of individuals who smoked. For all variables, age seemed to contribute the most out of all of the lifestyle factors for the positive changes in CIMT and CCA wall stiffness.CONCLUSION: Our data yielded correlations between CCA properties and cardiovascular risk, as well as between CIMT and arterial stiffness. We were also able to demonstrate an increase in thickness of the CIMT in patients who have been exposed by tobacco through the use of ultrasound. Further large scale studies comparing patients with multiple cardiac risk factors need to be performed to confi rm the utility of ultrasound fi ndings of cardiovascular disease and stroke.Allen R.Yu Bima Hasjim Luke E.Yu Christopher Gabriel Alexander Anshus Jonathan B.Lee Michael J.
