Active hepatitis B vaccination of dialysis patients and medical staff
1984
AbstractActive hepatitis B vaccination of dialysis patients and medical staff. One hundred six patients with terminal renal insufficiency and 29 medical personnel were given three doses of hepatitis B vaccine at an interval of 0, 1, and 6 months (Merck, Sharp and Dohme, West Point, Pennsylvania, part of a joint study no. 649). Chronic hemodialysis patients (N = 99) received 40 µg vaccine (V) i.m. Uremic patients, who were just about to start chronic dialysis treatment (N = 7), were given 40 µg V, and at the first vaccination 3ml hyperimmune globulin (HBIG) in addition. The medical personnel was alternately vaccinated with 20 µg V (N = 8), 40 µg (N = 11), 40 µg V, and 3ml HBIG at the first v…
Role and outcomes of laparoscopic cholecystectomy in the elderly.
2014
Abstract Introduction : Laparoscopic cholecystectomy is the standard of treatment for gallstones disease and acute colecystitis. The prevalence of this disease increases with age and the population is aging in industrialized countries. So, in this study we report our experience in the treatment of gallstone disease in elderly patients, particularly analyzing the outcomes of laparoscopic approach. Methods : Between January 2010 and May 2014 we performed a total of 1227 cholecystectomies. In this retrospective study age group was the primary independent variable: 351 patients were 65–79 years of age and 65 were 80 years of age or older. Results : Only 65 patients (5.3%) of all population had …
“Relaparoscopic” management of surgical complications: The experience of an Emergency Center
2015
Background/aim: Laparotomy has been the approach of choice for re-operations in patients with surgical complications. The aim of this retrospective analysis was to evaluate the feasibility and the safety of laparoscopic approach for the management of general abdominal surgery complications. Materials and methods: We report a retrospective review of 75 patients who underwent laparoscopic evaluation for postoperative complications over a 4-year period. Primary outcomes (resolution rate by exclusive laparoscopic approach, conversion rate, further surgery rate) and secondary outcomes (mortality, hospitalization, prolonged ileus, wounds problems and median operative time) were evaluated. Results…
Functional networks of motor inhibition in conversion disorder patients and feigning subjects
2016
The neural correlates of motor inhibition leading to paresis in conversion disorder are not well known. The key question is whether they are different of those of normal subjects feigning the symptoms. Thirteen conversion disorder patients with hemiparesis and twelve healthy controls were investigated using functional magnetic resonance tomography under conditions of passive motor stimulation of the paretic/feigned paretic and the non-paretic hand. Healthy controls were also investigated in a non-feigning condition. During passive movement of the affected right hand conversion disorder patients exhibited activations in the bilateral triangular part of the inferior frontal gyri (IFG), with a…
A 3-week feed restriction after weaning as an alternative to a medicated diet: effects on growth, health, carcass and meat traits of rabbits of two g…
2017
Feed restriction after weaning is widely used in meat rabbit farms to promote health and reduce mortality, but this practice impacts negatively on rabbit growth and slaughter performance. This study compared a 3-week post-weaning feed restriction with ad libitum medicated feeding, evaluating effects on feed intake, growth, health, carcass and meat quality of rabbits of two genotypes: Italian White pure breed and Hycole hybrid×Italian White crossbred. A total of 512 rabbits at 36 days of age, of both sexes and two genotypes, were divided into four homogeneous groups assigned, from 36 to 57 days of age, to different feeding programmes (FP): restricted non-medicated (R-N), ad libitum non-medic…
Rapid growth predisposes broilers to necrotic enteritis
2019
Over the past 50 years, intentional genetic selection within the broiler industry has led to major improvements in both body weight gain (BWG) and feed conversion efficiency. Next to its economic advantages, enhancing BWG can increase the risk of metabolic and skeletal disorders. The aim of this study was to examine whether higher BWG is a predisposing factor for broiler necrotic enteritis. In this study, 300 broilers were challenged with Clostridium perfringens using a well-established, previously described challenge model. It was found that birds with higher body weight (BW) and BWG before challenge were predisposed to develop more severe necrotic enteritis lesions. After challenge, the a…
Does conversion during minimally invasive rectal surgery for cancer have an impact on short-term and oncologic outcomes? Results of a retrospective c…
2021
International audience; Background: Although minimally invasive rectal surgery (MIRS) for cancer provides better recovery for similar oncologic outcomes over open approach, conversion is still required in 10% and its impact on short-term and long-term outcomes remains unclear. The aim of our study was to evaluate the impact of conversion on postoperative and oncologic outcomes in patients undergoing MIRS for cancer. Methods: From June 2011 to March 2020, we reviewed 257 minimally invasive rectal resections for cancer recorded in a prospectively maintained database, with 192 robotic and 65 laparoscopic approaches. Patients who required conversion to open (Conversion group) were compared to t…

Surgical conversion with graft salvage as a definitive treatment for persistent type II endoleak causing sacenlargement
2015
Objective The goal of this study was to present open surgical conversion with graft salvage or "semiconversion" as a definitive and safe treatment for untreatable and persistent type II endoleaks causing sac enlargement after endovascular aneurysm repair. Methods Between January 2001 and December 2014, 25 of 1623 endovascular aortic repair (EVAR) patients were selected as candidates for open semiconversion. The indication was persistent type II endoleak in 13 patients (12 of whom received previous attempts of embolization), type I and II endoleak in 2 patients, and sac growth without imaging evidence of endoleak in the other 10. After the infrarenal aorta was prepared (via a retroperitoneal…
Fusion of technology management and financing management - Amazon's transformative endeavor by orchestrating techno-financing systems
2020
Amazon became the world R&D leader in 2017 by rapidly increasing R&D investment. Its R&D investment in 2017 was double that of 2015, 5 times that of 2012, and 10 times that of 2011. This rapid increase continued in 2018, and Amazon accomplished a skyrocketing increase in its market capitalization, closing to being the world's biggest company. Such a rapid increase in R&D and subsequent market value has raised questions about how to conduct R&D and secure a large amount of funds needed for high-risk investments. Amazon has provided hypothetical answers to both of these questions. Amazon has been conducting innovative R&D to transform routine or periodic alterations into significant improveme…
