过去的几十年里,尽管对互惠合作系统稳定性的理解取得了较大的进展,但在解释互惠关系如何保持稳定方面仍然存在两个基本问题。(i)如何解决互惠合作双方之间的资源冲突?(ii)当存在不怎么合作和/或完全不合作的共生体时,为什么合作的共生体没有被不合作的个体竞争排斥掉?过去许多关于互惠稳定性的解释都假设互惠合作双方的相互作用是对称的。然而,在大多数共生关系中,宿主和共生体之间的相互作用在不同水平上表现出不同程度的非对称性。本文我们回顾了互惠合作系统中的三种主要的非对称相互作用:(i)收益非对称,也就是合作双方的实力非对称性;(ii)潜在进化速率非对称性;(iii)宿主和共生体之间的信息非对称性。我们认为,互惠合作系统非对称性有助于解释合作和冲突行为的不确定性(合作与竞争的内生不确定性),以及为什么宿主和共生体都呈现出多样化的表型特征,而合作仍可占主导地位。

Alzheimer’s disease (AD) is the most common neurodegenerative disease causing an alteration of life quality in the terminal stage. The purpose was to report 14 years of experience about the early impact on the quality of life of patients with AD. Methodology: Descriptive retrospective study over 14 years in the geriatric department of Pitié Salpêtrière Hospital, using the activity of daily living, Instrumental activity of daily living, neuropsychological inventory and Hoen Yahr scale evaluated at the time of diagnosis of AD according to the National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer Disease’s and Related Disorders Association diagnostic criteria. Results: A total of 214 exploitable files had been listed. At the moment of diagnosis, the mean age was 82.1 years with extremes 68 to 95 with sex ratio 1.6 in women’s favor. The mean socio-cultural level was 4.9 with extremes about 0 to 7. There was poly pathology with a mean Cumulative Illness Rate Scale = 4.6 with extremes 0 to 16. the mean cognitive status was moderate = 22.5 with extremes 0 to 30. Quality life showed moderate impairment of IADL = 9.2 with extreme 3 to 11 compared to activity of daily living. The activity of daily living was more affected in 68 - 80-year-olds, while poly pathology impacted more on IADL in men. The cognitive impairment was more deficient in IADL when the MMSE test was low. The common disorders at the NPI were psychological, behavioral and psychotic. Conclusion: At the early diagnosis of Alzheimer’s Disease cognitive deficiencies were predominant and influenced on global Instrumental activity and psychological, behavioral disorders.

Background: An Intrauterine device (IUD) is a long-acting reversible contraceptive commonly used in clinical practice. Its insertion in the uterus is simple and safe. But sometimes, complications can occur. Case Report: Herein, we report a case of successful laparoscopic removal of a missing IUD Copper-T, mis-inserted in a 32-year-old woman, 4 months after she delivered by caesarian section, and presented persistent lower abdominal pain lasting 6 months. Uterine ultrasound was unremarkable, but a plain abdominopelvic X-ray confirmed the presence of the Copper-T inside the abdominal cavity. Conclusion: Insertion of IUD is simple and safe. When the diagnosis of uterine perforation following its insertion is clinically suspected and radiologically confirmed, laparoscopy, when available, remains one of the best options for removal.

Introduction: The Six Sigma methodology is an opportunity for a better understanding of the performance of analytical methods and for a better adaptation of the quality control management policy of the medical biology laboratory. Using the sigma metric, this study assessed the performance of the Biochemistry analytical system of a medical biology laboratory in Côte d'Ivoire. Methods: Six Sigma methodology was applied to 3 analytes (alanine aminotransferase, glucose and creatinine). Performance indicators such as measurement imprecision and bias were determined based on the results of internal and external quality controls. The sigma number was calculated using the total allowable error values proposed by Ricos et al. Results: For both control levels, ALT had a sigma number greater than 6 (7.6 for normal control and 7.9 for pathological control). However, low sigma numbers, less than or equal to 2 for creatinine (1.4 for normal control and 2 for pathological control) and less than 1 for glucose were found. Conclusion: This study revealed good analytical performance of ALT from the point of view of 6 sigma analysis. However, modifications to the overall quality control procedure for glucose and creatinine are needed to improve their analytical performance. The study should be extended to the entire laboratory’s analytes in order to modify the strategies of quality control procedures based on metric analysis for an overall improvement in analytical performance.

Background: Diabetes is a known risk factor for susceptibility and severity of COVID-19 infection. It may also be a complication of COVID-19. Many hypotheses have been proposed to explain this condition. It may be due to the effect of SARS-CoV-2 on β cells or drug-related side effects. In children, there is a paucity of data on the burden of this complication. Objective: We aimed to report a case of secondary diabetes during COVID-19 in a pediatric unit. Case Presentation: A 16-year-old girl presented with severe respiratory distress. She was treated for COVID-19 infection with antibiotics and corticosteroids. On day 6 of treatment, she developed polyuria and polydipsia. A random blood glucose test showed hyperglycaemia. The diagnosis of secondary diabetes was maintained. Conclusion: Covid-19 infection can be complicated by diabetes in children. It is essential to monitor blood glucose levels regularly.
