Science as a Matter of Honour: How Accused Scientists Deal with Scientific Fraud in Japan.

Practices related to research misconduct seem to have been multiplied in recent years. Many cases of scientific fraud have been exposed publicly, and journals and academic institutions have deployed different measures worldwide in this regard. However, the influence of specific social and cultural environments on scientific fraud may vary from society to society. This article analyzes how scientists in Japan deal with accusations of scientific fraud. For such a purpose, a series of scientific fraud cases that took place in Japan has been reconstructed through diverse sources. Thus, by analyzing those cases, the social basis of scientific fraud and the most relevant aspects of Japanese cultural values and traditions, as well as the concept of honour which is deeply involved in the way Japanese scientists react when they are accused of and publicly exposed in scientific fraud situations is examined.

Right versus left laparoscopic colectomy for colon cancer: does side make any difference?

PURPOSE: To compare the intraoperative and postoperative outcomes between right laparoscopic colectomy (RLC) and left laparoscopic colectomy (LLC) for colon cancer. METHOD: Patients who underwent elective RLC or LLC for colon cancer between January 2004 and December 2014 were identified and elected for a retrospective analysis. Primary outcomes were technical difficulty (including operative time, intraoperative complications, and conversion rate) and postoperative outcome (including postoperative complications, length of hospital stay, reinterventions, readmissions, and mortality). RESULTS: A total of 547 patients (mean age: 68.5 years old; 48.4% males) were analyzed. The RLC group had a higher mean age (71 vs 65; p < 0.001), ASA 3/4 grade (36 vs 26%; p = 0.02), and comorbidity rate (61 vs 48%, p = 0.003). Regarding technical difficulty, no difference was found between the groups in intraoperative complications (4.1 vs 5.9%; p = 0.34) or conversion rate (6.2 vs 3.9%, p = 0.24). Mean operative time was significantly shorter for RLC (162 vs 185 min, p < 0.001). Regarding postoperative outcome, the RLC group had a higher overall morbidity (20.5 vs 13.3%, p = 0.03), ileus (10.6 vs 2.4%, p < 0.001), and a longer hospital stay (4.7 vs 3.9 days, p = 0.003), with no differences regarding reoperations, readmissions, or mortality. The multivariate analysis showed that RLC were independently associated with a longer operative time and postoperative ileus. CONCLUSIONS: RLC for colon cancer was independently associated with a shorter operative time, an increased risk of ileus, and a longer hospital stay than left laparoscopic colectomy in high-volume centers.

Pyogenic liver abscess: current status and predictive factors for recurrence and mortality of first episodes.

BACKGROUND: In times of modern surgery, transplantation and percutaneous techniques, pyogenic liver abscess (PLA) has essentially become a problem of biliary or iatrogenic origin. In the current scenario, diagnostic approach, clinical behavior and therapeutic outcomes have not been profoundly studied. This study analyzes the clinical and microbiological features, diagnostic methods, therapeutic management and predictive factors for recurrence and mortality of first episodes of PLA. METHODS: A retrospective single-center study was conducted including 142 patients admitted to the Hospital Italiano de Buenos Aires, between 2005 and 2015 with first episodes of PLA. RESULTS: Prevailing identifiable causes were biliary diseases (47.9%) followed by non-biliary percutaneous procedures (NBIPLA, 15.5%). Seventeen patients (12%) were liver recipients. Eleven patients (7.8%) died and 18 patients (13.7%) had recurrence in the first year of follow up. The isolation of multiresistant organisms (p = 0.041) and a history of cholangitis (p < 0.001) were independent risk factors for recurrence. Mortality was associated with serum bilirubin >5 mg/dL (p = 0.022) and bilateral involvement (p = 0.014) in the multivariate analysis. CONCLUSION: NBPLA and PLA after transplantation may be increasing among the population of PLA in referral centers. History of cholangitis is a strong predictor for recurrence. Mortality is associated to hiperbilirrubinemia and anatomical distribution of the lesions.

Anomalies in the early stages of plant transgenesis: interests and interpretations surrounding the first transgenic plants.

The origins of plant transgenesis are discussed and the experiments that led to the first transgenic plants are analyzed. This process involved a series of actors, practices and interests specific to biotechnology. Consensus about the meaning of fundamental experiments was also at issue here. These events illustrate some of the conflicts related to genetically modified organisms, since scientists had different responses to plant transgenesis at the time of the first experiments, and opinions of the anomalies in those experiments varied. Thus, this article analyzes the interests and interpretations surrounding the first experiments involving transgenic plants.

Protocol for extended antibiotic therapy after laparoscopic cholecystectomy for acute calculous cholecystitis (Cholecystectomy Antibiotic Randomised Trial, CHART).

INTRODUCTION: Acute calculous cholecystitis represents one of the most common complications of cholelithiasis. While laparoscopic cholecystectomy is the standard treatment in mild and moderate forms, the need for antibiotic therapy after surgery remains undefined. The aim of the randomised controlled Cholecystectomy Antibiotic Randomised Trial (CHART) is therefore to assess if there are benefits in the use of postoperative antibiotics in patients with mild or moderate acute cholecystitis in whom a laparoscopic cholecystectomy is performed. METHODS AND ANALYSIS: A single-centre, double-blind, randomised trial. After screening for eligibility and informed consent, 300 patients admitted for acute calculus cholecystitis will be randomised into two groups of treatment, either receiving amoxicillin/clavulanic acid or placebo for 5 consecutive days. Postoperative evaluation will take place during the first 30 days. Postoperative infectious complications are the primary end point. Secondary end points are length of hospital stay, readmissions, need of reintervention (percutaneous or surgical reinterventions) and overall mortality. The results of this trial will provide strong evidence to either support or abandon the use of antibiotics after surgery, impacting directly in the incidence of adverse events associated with the use of antibiotics, the emergence of bacterial resistance and treatment costs. ETHICS AND DISSEMINATION: This study and informed consent sheets have been approved by the Research Projects Evaluating Committee (CEPI) of Hospital Italiano de Buenos Aires (protocol N° 2111). RESULTS: The results of the trial will be reported in a peer-reviewed publication. TRIAL REGISTRATION NUMBER: NCT02057679.

Anomalias en los comienzos de la transgenesis vegetal: intereses e interpretaciones en torno a las primeras plantas transgenicas / Anomalies in the early stages of plant transgenesis: interests and interpretations surrounding the first transgenic plants

Se presentan los orígenes de la transgénesis vegetal, analizando los experimentos que llevaron a la obtención de las primeras plantas transgénicas. Aquí se entrecruzan actores, prácticas e intereses que resultan emblemáticos de la biotecnología. Se trata, además, de un caso donde se pone en juego el consenso sobre el sentido de experimentos fundamentales. Estos sucesos permiten ilustrar parte de los conflictos en los que se involucran los organismos genéticamente modificados, pues en torno a estos primeros experimentos los científicos articularán representaciones distintas sobre la transgénesis vegetal, valorando de un modo distinto las anomalías que presentaban los primeros experimentos. De este modo, se analizan los intereses e interpretaciones en torno a los primeros experimentos con plantas transgénicas.

Subjetividad y aparato psíquico: acerca de quietudes e in-quietudes / Subjectivity and psychic apparatus: on quietnesses and unquietnesses

El presente trabajo discute reflexivamente sobre acontecimientos socio-políticos que podrían indicar un proceso de transformación de la subjetividad. Para comprender ese cambio es preciso investigar cómo se construye una subjetividad, es decir, cómo se construyen modos concretos, imaginarios y simbólicos de hacer, pensar, sentir, decir y fantasear. Partimos de la convicción de que el sujeto es un ser histórico social atravesado por la necesidad y el deseo. Tal conformación indica la ineludible tarea de comprender el sistema social en el que se desarrolla la subjetividad dado que es en y desde las territorialidades que son y pueden ser-allí en las que se encuentran o no las posibilidades de su realización. El proceso de producción capitalista origina la fetichización de la mercancía (dinámica bajo la que se cosifica al trabajador) y la reificación del capital, siendo una consecuencia de su imperio, la reducción del sujeto histórico social a la alienación individual. Sugerimos que el deseo (de transformar las estructuras de explotación y dominación) es determinante y acaso anterior a la conciencia de la opresión. Por consiguiente, la raíz de todo acto revolucionario se encuentra en la poesía, en la palabra, en aquello que despierta el deseo de transformación
