Soins intégrés: comment accompagner un changement de culture [Integrated care: how to support a culture change?].

The primary care center at Lausanne University Hospital trains residents to new models of integrated care. The future GPs discover new forms of collaboration with nurses, pharmacists or social workers. The collaboration model includes seeing patients together or delegating care to other providers, with the aim of improving the efficiency of a patient-centered care approach. The article includes examples of integrated care in consultation for travelers, victims of violence, pharmacist medication adherence counseling, medicosocial team work for alcohol use disorders and nurse practitioners' primary care for asylum seekers.

Effect of Tocopherol Extract, Staphylococcus carnosus Culture, and Celery Concentrate Addition on Quality Parameters of Organic and Conventional Dry-Cured Sausages

The effects of the addition to sausage mix of tocopherols (200 mg/kg), a conventional starter culture with or without Staphylococcus carnosus, celery concentrate (CP) (0.23% and 0.46%), and two doses of nitrate (70 and 140 mg/kg expressed as NaNO(3)) on residual nitrate and nitrite amounts, instrumental CIE Lab color, tocol content, oxidative stability, and overall acceptability were studied in fermented dry-cured sausages after ripening and after storage. Nitrate doses were provided by nitrate-rich CP or a chemical grade source. The lower dose complies with the EU requirements governing the maximum for ingoing amounts in organic meat products. Tocopherol addition protected against oxidation, whereas the nitrate dose, nitrate source, or starter culture had little influence on secondary oxidation values. The residual nitrate and nitrite amounts found in the sausages with the lower nitrate dose were within EU-permitted limits for organic meat products and residual nitrate can be further reduced by the presence of the S. carnosus culture. Color measurements were not affected by the CP dose. Product consumer acceptability was not affected negatively by any of the factors studied. As the two nitrate sources behaved similarly for the parameters studied, CP is a useful alternative to chemical ingredients for organic dry-cured sausage production.

The role of culture in international students' image formation: the emergence of expected and perceived university image

Tämän tutkimuksen tavoitteena oli selvittää, vaikuttaako kansainvälisen opiskelijan kulttuuritausta opiskelijan odotetun ja koetun yliopistoimagon muodostumiseen. Jotta kulttuurin vaikutuksia yliopistoimagoon voitiin tutkia, tutkimuksessa tunnistettiin yliopistoimagon muodostumiseen oleellisesti vaikuttavat tekijät. Kulttuurin roolia organisaation imagon muodostumisessa ei ole tutkittu aiemmissa tieteellisissä julkaisuissa. Näin ollen tämän tutkimuksen voidaan katsoa edistäneen nykyistä imagotutkimusta. Tutkimuksen kohdeyliopistona oli Lappeenrannan teknillinen yliopisto (LTY). Tutkimuksen empiirinen osa toteutettiin kvantitatiivisena Internet - pohjaisena kyselytutkimuksena tilastollisen analyysin menetelmin. Otos (N=179) koostui kaikista Lappeenrannan teknillisessä yliopistossa lukuvuonna 2005-2006 opiskelleista kansainvälisistä opiskelijoista. Kyselyyn vastasi 68,7 % opiskelijoista. Johtopäätöksenä voidaan todeta, että kulttuurilla ei ole merkittävää vaikutusta yliopistoimagon muodostumiseen. Tutkimuksessa saatiin selville, että yliopiston Internet-sivujen laatu vaikuttaa positiivisesti odotetun yliopistoimagon muodostumiseen, kun taas koettuun yliopistoimagoon vaikuttavat positiivisesti odotettu yliopistoimago, pedagoginen laatu sekä opetusympäristö. Markkinoinnin näkökulmasta tulokset voidaan vetää yhteen toteamalla, että yliopistojen ei tarvitsisi räätälöidä tutkimuksessa tunnistettuja imagoon vaikuttavia tekijöitä eri kulttuureistatulevia opiskelijoita varten.

Evaluation of the integrity of human corneal epithelium maintained in organ-culture during eye banking using Corneamax®

Purpose: Mediums have been developed to conserve corneal endothelium in organ-culture during eye banking. CorneaMax® is used by 25% of Eye Bank in Europe. Only little is known about conservation of corneal epithelium with this medium during banking. Its preservation could be of interest in clinic to cure corneal disease with stem cells deficiency. Therefore, we wanted to examine the integrity of human corneal epithelium maintained in CorneaMax®. Methods: Human corneas, considered unsuitable for transplantation, were obtained from the Eye Bank in Lausanne. Average post-mortem time was 14 hours. Cornoscleral rings were maintained in organ-culture in Corneamax® at 32°C. Samples were formalin-fixed after period ranging from 0 (D0) to 35 days (D35, N=5 for each time points) and stained with H&E. Proliferation and apoptosis were evaluated by immunostaining with antibody against Ki67 and Caspase3 respectively. Results: Corneas, which were not in organ-cultured (D0), showed different morphology, including intact epithelium with 5 to 7 layers, but also completely denuded basement membrane. In two cases, at D0, the epithelium lost its adherence to the basal lamina of the cornea creating a large epithelial sheet. During the two first days, corneas and limbus area lost totally their epithelium, except for some remaining limbal basal cells. From day 2 to day 10, regeneration of the epithelium took place, starting from the limbal region in direction to the central cornea. From day 10 to day 35, corneal epithelium appeared as an atrophic epithelium, consisting of only two cell layers. Proliferation happened in the whole cornea during the 35 days of organ-culture, as shown by Ki67 positive cells. Apoptosis was rarely detected in the corneal epithelium. Conclusions: Corneas maintained in CorneaMax® showed a complete disappearance of the corneal epithelium during the two first days and a conservation of limbal basal cells in the limbal region. These remaining cells allowed a full regeneration of the tissue, leading to an atrophic epithelium, composed of only two cell layers. This atrophic epithelium could be seen in all the organ-cultured corneas during the 35 days of conservation. This study is a first step to develop medium in organ-culture in order to conserve corneal epithelial cells.

Forensic science culture

Heretofore the issue of quality in forensic science is approached through a quality management policy whose tenets are ruled by market forces. Despite some obvious advantages of standardization of methods allowing interlaboratory comparisons and implementation of databases, this approach suffers from a serious lack of consideration for forensic science as a science. A critical study of its principles and foundations, which constitutes its culture, enables to consider the matter of scientific quality through a new dimension. A better understanding of what pertains to forensic science ensures a better application and improves elementary actions within the investigative and intelligence processes as well as the judicial process. This leads to focus the attention on the core of the subject matter: the physical remnants of the criminal activity, namely, the traces that produce information in understanding this activity. Adapting practices to the detection and recognition of relevant traces relies on the apprehension of the processes underlying forensic science tenets (Locard, Kirk, relevancy issue) and a structured management of circumstantial information (directindirect information). This is influenced by forensic science education and training. However, the lack of homogeneity with regard to the scientific nature and culture of the discipline within forensic science practitioners and partners represents a real challenge. A sound and critical reconsideration of the forensic science practitioner's roles (investigator, evaluator, intelligence provider) and objectives (prevention, strategies, evidence provider) within the criminal justice system is a means to strengthen the understanding and the application of forensic science. Indeed, the whole philosophy is aimed at ensuring a high degree of excellence, namely, a dedicated scientific quality.
