Published: March 2018

Introduction: Postoperative delirium and pain are common complications in adults, and are difficult both to prevent and treat. Obstructive sleep apnea (OSA) is prevalent in surgical patients, and has been suggested to be a risk factor for postoperative delirium and pain. OSA also might impact pain perception, and alter pain medication requirements. This protocol describes an observational study, with the primary aim of testing whether OSA is an independent predictor of postoperative complications, focusing on (i) postoperative incident delirium and (ii) acute postoperative pain severity. We secondarily hypothesize that compliance with prescribed treatment for OSA (typically continuous positive airway pressure or CPAP) might decrease the risk of delirium and the severity of pain.

Methods and analysis: We will include data from patients who have been enrolled into three prospective studies: ENGAGES, PODCAST, and SATISFY-SOS. All participants underwent general anesthesia for a non-neurosurgical inpatient operation, and had a postoperative hospital stay of at least one day at Barnes Jewish Hospital in St. Louis, Missouri, from February 2013 to December 2017.  Patients included in this study have been assessed for postoperative delirium and pain severity as part of the parent studies. In the current study, determination of delirium diagnosis will be based on the 3-minute Diagnostic Confusion Assessment Method, and the Visual Analogue Pain Scale will be used for pain severity. Data on OSA diagnosis, OSA risk and compliance with treatment will be obtained from the preoperative assessment record. Other variables that are candidate risk factors for delirium and pain will also be extracted from this record. We will use logistic regression to test whether OSA independently predicts postoperative delirium and linear regression to assess OSAs relationship to acute pain severity. We will conduct secondary analyses with subgroups to explore whether these relationships are modified by compliance with OSA treatment.

Published: March 2018

Background:The concept of locus of control of reinforcement was introduced by Julian Rotter and has been the focus of intense research for nearly half a century.  Surprisingly little research has been directed at clarifying antecedents of locus of control (LOC) orientations in adult men apart from a few small studies. We previously identified a number of independent antecedents associated with women’s LOC, including features of their parents and early childhood. This raised the question as to whether these factors were also associated with the development of LOC in men.

Methods:To identify antecedents of LOC orientations in a representative population of women we previously analysed information concerning characteristics of their parents and their own childhood experiences using pregnant women taking part in the Avon Longitudinal Study of Parents and Children (ALSPAC).  Here we use the same design to determine whether their male partners have similar antecedents of LOC orientation. As previously, we use a hypothesis-free exposome technique using all available information on the parents and childhood of the individuals.

Results:We show that men had many of the same antecedent characteristics as the women – in particular, their mother’s year of birth and father’s social group, being exposed to cigarette smoke prenatally, starting to smoke regularly before the age of 11, and having a friend die were all associated with being external. Associations of internality common to both were warm maternal care, being breast fed, being born in an area other than that where they currently live, attending boarding school and having a parent admitted to hospital.

Conclusions:In general, the antecedents of male external and internal personalities have many similarities to those of women, thus providing some features to inform the possible theoretical background as to how LOC might develop over time.
Error Bounds, Quadratic Growth, and Linear Convergence of Proximal Methods
Authors: Drusvyatskiy Dmitriy , Lewis Adrian S.
Published: March 2018

The proximal gradient algorithm for minimizing the sum of a smooth and nonsmooth convex function often converges linearly even without strong convexity. One common reason is that a multiple of the step length at each iteration may linearly bound the “error”—the distance to the solution set. We explain the observed linear convergence intuitively by proving the equivalence of such an error bound to a natural quadratic growth condition. Our approach generalizes to linear and quadratic convergence analysis for proximal methods (of Gauss-Newton type) for minimizing compositions of nonsmooth functions with smooth mappings. We observe incidentally that short step-lengths in the algorithm indicate near-stationarity, suggesting a reliable termination criterion.
Use of serum and peritoneal CEA and CA19-9 in prediction of peritoneal dissemination and survival of gastric adenocarcinoma patients: are they prognostic factors?

Published: March 2018

Introduction

To evaluate the impact of serum and peritoneal levels of tumour markers on peritoneal carcinomatosis and survival in gastric adenocarcinoma.

Materials and methods

Patients with gastric adenocarcinoma were evaluated with regard to serum and peritoneal carcinoembryonic antigen (CEA) and CA19-9. Numeric values and groupings based on serum and peritoneal cutoff values were used. Development of peritoneal carcinomatosis, including positive washing cytology, was regarded as main outcome. Gastric cancer outcomes as disease free and overall survival were analysed.

Results

There were 67 patients with a mean age of 60 ± 11 years. Positive peritoneal washing cytology was significantly associated with serum CA19-9 and high serum CA 19–9 group (P = 0.033 and P = 0.011, respectively). High peritoneal CEA was shown to be significantly associated with peritoneal carcinomatosis (P = 0.032). After a median follow up of 17 months, 48 patients (71.7%) were alive. Patients with peritoneal carcinomatosis showed significant poorer prognosis as shown by overall survival rate of 28.6%. Only serum CEA was significantly associated with lower disease free and overall survival (P = 0.002 and P = 0.001, respectively).

Discussion and conclusion

Serum CEA is shown to be significantly associated with poor prognosis for gastric cancer patients. Serum level of CA19-9 and high peritoneal CEA levels are significant predictors for positive peritoneal washing cytology and the development of peritoneal carcinomatosis, respectively. Therefore, the possible impact of serum and peritoneal tumor markers especially on the staging and prognosis of gastric cancer remains to be clarified by future studies.
Are we doing better? Barium enema reduction of intussusception
Authors: Pran L , Baijoo S , Rampersad B
Published: March 2018

Introduction

Intussuception remains one of the most common surgical abdominal emergencies in the paediatric population. The aim of this study was first to re-evaluate our non-operative reduction rate of intussusception using multiple interval barium enemas and second to investigate or discuss an audit cycle, providing evidence and validating the modification of clinical practice.

Materials and methods

This five-year retrospective study performed at one of two institutions at which a paediatric surgical service is offered. Individuals included were all patients under 12-years of age who were diagnosed with intussusception. Factors considered to be influential in the reduction of the intussusception were collected. End points were defined as successful barium enema reduction or surgical intervention. Results were compared with similar research published in 2010.

Results

Overall prevalence was found to be 12 cases/year, with a sample size of 60 patients, the mean age at presentation of 13.6 months. Barium enema reduction was attempted in 56/60 patients, while 4/60 patients had operative management as a first intervention. Overall reduction rate was 66% (37/56), 78% occurring on first attempt and 22% on the second attempt. There was no evidence of intussusception in 3/19 patients who had operative management as a second intervention. Delayed interval barium enema reduction demonstrated an improved reduction rate of 66% compared with single-use barium enema reduction of 41% (chi square 0.02).

Conclusion

A significant benefit was achieved by performing delayed interval enema reduction, which contributed to a 61% increased reduction rate, the actual reduction rate approaches 71%. The audit cycle remains of paramount importance to ensure optimum patient care.

Published: March 2018

Introduction

Anaemia is associated with cancer. In 2014 a new form was introduced in our department requesting a haemoglobin (Hb) result on every two-week wait referral for suspected colorectal cancer (CRC). The aim of this study was to review the impact of this intervention. In particular, the significance of any evidence of anaemia (without additional indices) was investigated.

Methods

A review was conducted of 1,500 consecutive suspected CRC referrals recorded prospectively over a 10-month period. Data on demographics, referral Hb, referral criteria and outcomes were analysed. Anaemia was defined according to World Health Organization criteria (Hb <120g/l for women, Hb <130g/l for men).

Results

Overall, 1,015 patients were eligible for inclusion in the study. Over a third (38.2%) were documented as anaemic on referral. These patients were three times more likely to be diagnosed with CRC than non-anaemic patients (odds ratio [OR]: 3.22, 95% confidence interval [CI]: 1.87–5.57). Using a more stringent threshold (Hb <100g/l for women and <110g/l for men), they were four times more likely to have CRC (OR: 4.27, 95% CI: 2.35–7.75). Almost a quarter (23.7%) were actually anaemic at the time of referral but not referred with anaemia. In this subgroup, there was a 2.8-fold increase in risk of CRC diagnosis compared with non-anaemic patients (adjusted OR: 2.77, 95% CI: 1.55–4.95).

Conclusions

Nearly a quarter of patients not referred with iron deficiency anaemia had evidence of anaemia and this was still associated with a higher rate of CRC detection. A full blood count alone might help to risk stratify symptoms such as change in bowel habit in patients on urgent pathways and identify those cases most likely to benefit from invasive investigation.

BACKGROUND

Amniocentesis is a common procedure, the primary purpose of which is to collect cells from the fetus to allow testing for abnormal chromosomes, altered chromosomal copy number, or a small number of genes that have small single- to multibase defects. Here we demonstrate the feasibility of generating an accurate whole-genome sequence of a fetus from either the cellular or cell-free DNA (cfDNA) of an amniotic sample.

METHODS

cfDNA and DNA isolated from the cell pellet of 31 amniocenteses were sequenced to approximately 50× genome coverage by use of the Complete Genomics nanoarray platform. In a subset of the samples, long fragment read libraries were generated from DNA isolated from cells and sequenced to approximately 100× genome coverage.

RESULTS

Concordance of variant calls between the 2 DNA sources and with parental libraries was >96%. Two fetal genomes were found to harbor potentially detrimental variants in chromodomain helicase DNA binding protein 8 (CHD8) and LDL receptor-related protein 1 (LRP1), variations of which have been associated with autism spectrum disorder and keratosis pilaris atrophicans, respectively. We also discovered drug sensitivities and carrier information of fetuses for a variety of diseases.

CONCLUSIONS

We were able to elucidate the complete genome sequence of 31 fetuses from amniotic fluid and demonstrate that the cfDNA or DNA from the cell pellet can be analyzed with little difference in quality. We believe that current technologies could analyze this material in a highly accurate and complete manner and that analyses like these should be considered for addition to current amniocentesis procedures.

Published: March 2018

This study aimed to determine the effect of addition of Soursop leaf extract to  edible film and its effect on the storage time of red grapes. This research had three main steps, soursop leaf extraction, edible film making, and application on red grapes storage time. Soursop leaves extract variation used in this research are 0.5; 1; and 1.5% (w/w total) and the best result was used to coat the red grapes. The results showed that the optimum composition was obtained on the edible film with the addition of 0.5% (w/w total) soursop leaf extract. The composition increased film thickness from 0.03 to 0.08 mm, decreased film’s tensile strength from 11.89 to 8.42 MPa, decreased elongation from 12.71 to 11.03%, decreased the Young Modulus from 0.935 to 0.764 MPa, and decreased the vapor transmission rate from 7.45 to 6.55 g/m2.hour. The 50% shrinkage of weight and 50% texture damage are used as parameters to measure the Red grapes storage time. Based on weight shrinkage, red grapes storage time change from 24 days to 29 days by using an edible film coating without addition of extract, an extend to 32 days while using an edible film coating with addition of soursop leaf extract. Based on texture damage, red grapes storage time increased from 13 to 41 days if using an edible film coating without addition of extract, and increased to 40 days using an edible film coating with the addition of soursop leaf extract.

Authors: Fitriawan Fuad
Published: March 2018

Sperm abnormalities can occur by various causes. Abnormality of sperm is usually characterized by abnormal sperm motility and viability. This was caused by the inability of mitochondria on ATP-ase in producing ATP and ecto-enzyme Cik role in keeping the movement so that movement of sperm motility declines. Research that leads to total abnormal sperm DNA analysis is still rare. The purpose of this research was to get the results of the molecular characteristic picture of the overall characteristics of DNA loci that have abnormalities in bull sperm and get a picture of differences in overall DNA loci of abnormal and normal sperm. This research was conducted in October-December 2016. With the results of Group I consists of D, E with a percent similarity of 92.308%, group II consists of C and Group I with a percentage similarity of 50.125%, group II consists of A and B with a percent similarity of 100%, group II and group III with a percentage similarity of 0%. Based on the above data it can be concluded that the treatment A and B is not suspected to cause DNA damage compared to treatment C, D and E.

Quand les professionnels indépendants réinventent l’agence de communication
Authors: Brizard-Kim Kristell
Published: March 2018

De plus en plus de communicants s’émancipent du modèle « classique » de l’agence de communication, par la création de réseaux, de collectifs, de communautés, parfois liées par un espace de coworking, voire d’entreprises coopératives. Pour ces communicants, il s’agit de reprendre le pouvoir sur la rémunération de leur expertise et sur leur relation au travail, par l’exercice de leur profession en freelance. Les échanges via ces structures vont au-delà de la mutualisation de moyens ou de l’apport d’affaires : le renouveau des collectifs de freelances ou de l’entrepreneuriat collectif en témoigne. Ces nouveaux « Sublimes » questionnent, par leurs collaborations en dehors d’une entreprise commune, le métier même d’agence de communication, la répartition de la marge dégagée, le manque d’adaptation à la demande du client, mais aussi la concurrence et l’esprit de compétition en interne. Les éléments de langage déployés par ces entreprises collaboratives sont ainsi parfois très offensifs, visant directement les agences, dont la plupart de ces professionnels sont pourtant issus. Les freelances tentent ainsi de s’affranchir du modèle économique de l’agence de communication. Ce faisant, ils opèrent un retour à l’adhocratie entrepreneuriale qui présidait aux débuts du métier d’agence.
Communicators are increasingly emancipating themselves from the « classic » model of the communication agency, by creating networks, collectives, communities, sometimes linked by a coworking space or cooperative enterprises. For these professionals, it is a question of regaining power on the remuneration of their expertise and on their relationship to work, through the exercise of their profession as a freelancer. These exchanges via these structures go beyond the pooling of resources or bringing business: the renewal of free-lances’ groups or collective entrepreneurship attests to this. These new « Sublime » are questioning by their collaborations outside of a joint venture, the communication agency business model, the distribution of the margin, a lack of adaptation to customer demand, but also competition and spirit of internal competition. The language elements made by these companies are collaborative and sometimes directly offensive to agencies, while most of these professionals are stem from them. Freelancers are trying to overcome the economic model of the communication agency. In doing so, they operate a return to entrepreneurial adhocracy who presided over the beginnings of the agency business.
Quelles attitudes possèdent les futurs publicitaires envers la publicité et son éthique ? Analyse compréhensive des représentations sociales d’un corpus d’étudiants
Authors: Pochet Sophie
Published: March 2018

Cet article présente les résultats d’une étude menée sur 24 étudiants en Publicité et communication commerciale. L’investigation possède deux objectifs liés : premièrement, distribuer ces étudiants parmi des catégories d’attitudes par rapport à la publicité et son éthique et, en second lieu, sur base des mêmes données récoltées, présenter des propositions pour l’établissement d’un dispositif d’éducation critique à la publicité. Au moyen d’un entretien individuel semi-directif alliant l’approche compréhensive et la méthode du tri de cartes, les étudiants ont été confrontés à un tour des représentations sociales de la publicité présentes dans la littérature critique. Cette recherche a mis en lumière une nette tendance au cynisme vis-à-vis de l’éthique publicitaire dans le chef des étudiants se destinant au métier de publicitaire. Ces derniers conçoivent et acceptent pourtant comme vrais une majorité des écueils faits à la discipline. Ils envisagent difficilement les impacts et enjeux du discours et du secteur publicitaire si ce n’est sur les plus jeunes ou les personnes moins éduquées. Ils dédouanent la discipline en évoquant les campagnes non marchandes, la lucidité du consommateur et le caractère acquis, normal, de la situation. Enfin, leur capacité à imaginer des scénarios différents lorsqu’ils s’enquièrent des enjeux sociétaux de la publicité s’est avérée très parcellaire.

This article presents the results of a study carried out on 24 advertising students. The investigation comprises two interrelated objectives: firstly distribute these students among categories of attitudes toward advertising and its ethics and, secondly, on the basis of the same data, submit proposals for the establishment of a mechanism of critical education to advertising. Through semi directive interviews combining the comprehensive approach and the method of card sorts, students were confronted with the social representations of advertising present in the critical literature. This research has brought to light a clear tendency to cynicism toward advertising ethics in students intending to pursue a career in advertising. They nonetheless understand and accept as real a majority of reproaches formulated to the discipline. They hardly consider the impacts and issues of the advertising discourse and sector except on the younger or less educated people. They clear the discipline by mentioning the non profit campaigns, the clear-mindedness of the consumer and the acquired, normal, nature of the situation. Finally, their ability to imagine different scenarios when analyzing the societal issues of advertising has proved to be very fragmented

Déontologie : La méthode participative comme facteur d’acceptation et d’adhésion au code !
Authors: Cobut Eric
Published: March 2018

L’association belge de la communication interne (ABCI) a décidé en 2016, de réécrire son code de déontologie. Concevoir un document est une chose mais le faire accepter par ses utilisateurs en est une autre. Pour relever ce défi, l’ABCI a misé sur l’approche participative. Sur base de dix principes définis par le conseil d’administration, un groupe de réflexion, composé de cinq membres volontaires de l’association, s’attela à la rédaction d’un projet de charte. Ce dernier fut soumis à l’analyse critique de l’ensemble des membres de l’ABCI ainsi que d’un groupe d’étudiants en communication interne de l’université de Louvain. L’objectif poursuivi au travers de cette démarche visait non seulement à impliquer les professionnels de la communication dans l’élaboration du code mais aussi à répondre à leurs attentes. Les objections formulées permirent d’affiner le texte qui fut approuvé à l’unanimité en février 2017. Le code s’articule en deux parties : la mission et les six valeurs nécessaires à son exécution : intégrité, esprit de service, respect, orientation résultats, responsabilité et innovation.
Mots clés : déontologie, mission, participation, adhésion, implication, outil de gestion.
 
The Belgian Association for internal communication (ABCI) decided in 2016 to rewrite its code of ethics. Designing a document is one thing but getting it accepted by its users is another. To meet this challenge, the ABCI relied on the participatory approach. Based on 10 principles defined by the Board, a reflection group, consisting of five volunteer members of the association, started in the drafting of a charter. Subsequently, the latter was submitted to the critical analysis of all the members of the ABCI as well as a group of students in internal communication from the University of Louvain. The goal pursued through this approach was not only to involve communication professionals in the drafting of the code but to meet their expectations. The objections raised allowed to refine the text which was approved unanimously in February 2017. The code is divided into 2 parts: the mission and the six values for its execution, in this case: Integrity, service spirit, respect, results orientation, responsibility and innovation policy.

Published: March 2018

Acercarse a la obra de arquitectura a través del lente de las memorias de un viaje que ocurrió hace suficiente tiempo como para haberlo olvidado es, en gran medida, un arte. El arte de la memoria en la arquitectura, concebido como un concierto de recuerdos, experiencias y composiciones, se plantea como un caso de estudio que hace referencia a un viaje particular realizado por el arquitecto Rogelio Salmona, y que dirige la mirada a sus memorias de África. Se reflexiona sobre la hipótesis de que los recuerdos y reminiscencias de aquella experiencia hayan quedado guardados en su memoria para luego poder ser encontrados a través de fragmentos por quienes visitan, habitan o recorren su arquitectura.

Preditores de retenção e lealdade de clientes em academias de ginástica
Authors: Arcoverde David de França , Araújo Marcus Augusto Vasconcelos
Published: March 2018

A lealdade dos clientes deve ser encarada como uma vantagem sustentável e indispensável à sobrevivência de uma organização de serviços. Por isso, acadêmicos e profissionais têm se engajado nos últimos anos em estratégias voltadas para o aumento na percepção da qualidade do serviço e de barreiras que dificultem o abando precoce dos serviços contratados. O objetivo deste estudo foi verificar a influência da qualidade percebida e das barreiras relacionais à mudança na lealdade e na retenção de clientes em academias de ginástica. A pesquisa, de natureza descritiva, foi realizada em duas academias de ginástica com uma amostra n=228. As dimensões de Qualidade e de Barreiras Relacionais à Mudança foram tomadas como variáveis independentes e submetidas à análise de regressão logística para retenção e para lealdade. Os resultados demonstraram que os aspectos tangíveis associados ao serviço são a dimensão da qualidade que mais afeta a lealdade. O estudo preditivo da retenção apresentou a frequência de utilização do serviço como sendo a variável mais importante associada ao comportamento de recompra, seguido de empatia. Conclui-se que a qualidade de serviço e as barreiras influenciam positivamente na lealdade e na retenção de clientes, embora existam preditores diferentes para a retenção e a lealdade. Além disso, a qualidade tem um maior poder de influência do que as barreiras relacionais, especialmente na lealdade.
Análise de mercado e nível de concentração da indústria de papel tissue no Brasil
Authors: Souza Sebastião Décio Coimbra de , Bastos Samilla Lima
Published: March 2018

O objetivo dessa pesquisa foi avaliar o nível de concentração do mercado brasileiro de papéis tissue e analisar seus reflexos em termos de desempenho relativo por linha de produto. Papéis tissue, ou papéis sanitários, compõem um segmento que abrange a produção de uma linha bastante variada de produtos, incluindo desde papel higiênico, papel toalha até fraldas e lenços para bebês, cujas características mais aparentes são maciez e textura aveludada, constituindo-se em um nicho de mercado diferenciado. A participação do segmento tissue na produção total de papéis no Brasil tem apresentado crescimento constante nos últimos anos, e estudos prospectivos do setor indicam que esse indicador deve se manter acima de 4% ao ano até 2020. A pesquisa foi exploratória e descritiva, com abordagem mista, sendo parte qualitativa, com a abordagem do método interpretativo Estrutura-Conduta-Desempenho (ECD), e parte quantitativa, com o cálculo dos índices de concentração de mercado, e a estratificação da linha de produtos. De forma geral, os resultados mostraram que o segmento apresenta uma estrutura industrial de baixa concentração de mercado, tendência que tem se consolidado nos últimos anos. Através dos resultados foi possível concluir que devido à forte concorrência no segmento, com diferenciação de itens por linha de produtos, o mix de tecnologias de processo, e o foco em eficiência operacional e na redução de custos, condicionam os padrões de conduta e as estratégias de produção, o que permitiu a introdução de novos produtos, de melhor qualidade, sem que houvesse aumentos de preços significativos. Essa configuração de fatores é a característica mais importante para sustentar a tendência de crescimento desse segmento industrial.

Authors: Merše Lovrinčević Katarina , Lepičnik Vodopivec Jurka
Published: March 2018

Uvod: Tandemsko dojenje ali dojenje sorojencev je slabo poznan koncept. Matere, ki tandemsko dojijo, se srečujejo s socialno stigmo in slabo oporo s strani zdravstvenih strokovnjakov. Namen raziskave je bil proučiti znanje o  tandemskem dojenju med študenti zdravstvenih ved.Metode: Uporabljen je bil kvantitativni eksplorativni neeksperimentalni raziskovalni dizajn. V priložnostni vzorec so bili vključeni študenti zdravstvene nege (n = 66) in dietetike (n = 24). Podatki so bili zbrani s strukturiranim vprašalnikom (Cronbach α = 0,914). Uporabljena je bila opisna statistika, test hi-kvadrat in analiza variance.Rezultati: Da je popolnoma fiziološko, da ženska prekine dojenje starejšega otroka, če rodi naslednjega otroka, meni 50,7 % (n = 36) žensk in 84,2 % (n = 16) moških (χ2 = 6,898, p = 0,009). Kaj je izključno dojenje v prvih šestih mesecih, ve 79,2 % (n = 19) študentov dietetike in le 54,5 % (n = 36) študentov zdravstvene nege (χ2 = 4,489, p = 0,034). Nepravilnost trditve, da dojenčki v primeru tandemskega dojenja težje pridobivajo telesno težo, je prepoznalo 86,3 % (n = 44) žensk in 13,7 % (n = 7) moških.Diskusija in zaključek: V raziskavo vključeni študentje so izkazali pomanjkljivo znanje tako o dojenju na splošno kakor tudi o tandemskem dojenju. V študijski program bi bilo treba vnesti več vsebin o dojenju.

Published: March 2018

Uvod: Medicinske sestre v enotah intenzivne terapije uravnavajo ciljno vrednost glukoze v krvi pri kritično bolnih po sprejetih in veljavnih protokolih. Namen raziskave je bil raziskati prednosti in slabosti različnih protokolov vodenja  vrednosti glukoze v krvi pri kritično bolnih.Metode: Uporabljen je bil sistematični pregled znanstvene in strokovne literature. Iskanje literature je potekalo od 1. 2. 2017 do 8. 8. 2017. V pregled so bile vključene naslednje baze: COBIB.SI, Digitalna knjižnica Slovenije – Dlib.si, CINAHL, ProQuest, PubMed in Google Učenjak. Iskanje je potekalo z različnimi kombinacijami ključnih besed v slovenskem in angleškem jeziku: prednosti, slabosti, medicinske sestre, kritično bolni, glukoza v krvi in protokoli za vodenje vrednosti glukoze v krvi. Uporabljen je bil Boolov operater AND. Iz iskalnega nabora 1064 zadetkov je bilo v končno analizo  vključenih 15 člankov. Za obdelavo podatkov je bil uporabljen model analize konceptov.Rezultati: Identificirana so bila tri tematska področja: (1) primernost različnih protokolov za vodenje vrednosti glukoze v krvi, (2) delovne obremenitve medicinskih sester pri teh protokolih in (3) varnost protokolov. Prednosti računalniško podprtega protokola za vodenje vrednosti glukoze v krvi so v boljšem doseganju ciljne vrednosti koncentracije glukoze v krvi, slabosti pa v pojavu odstopanj v zvezi z načrtovanim časom za merjenje glukoze v krvi.Diskusija in zaključek: Nekatere raziskave ugotavljajo prednosti računalniško podprtih protokolov za vodenje vrednosti glukoze v krvi v smislu tehnoloških izboljšav, zmanjšanja delovnih obremenitev medicinskih sester in izboljšanja varnosti pacientov. Raziskava prispeva k izboljševanju klinične prakse pri delu s kritično bolnimi pacienti.

Uvod: Za boljše doseganje kakovosti življenja pacientov s kronično obstruktivno pljučno boleznijo je slednje treba poučiti o značilnostih bolezni ter o ukrepih za njeno učinkovito samoobvladovanje. Namen raziskave je bil ugotoviti pogostost dokumentiranja in vrsto dokumentiranih navodil o življenjskem slogu in samoobvladovanju bolezni v bolnišnični dokumentaciji pacientov s kronično obstruktivno pljučno boleznijo.Metode: Izvedena je bila retrospektivna kvantitativna raziskava, v kateri je bila pregledana celotna bolnišnična dokumentacija (terapevtski listi, liste zdravstvene nege, arhivi zdravstvenovzgojnih šol, odpustna pisma) 253 pacientov s kronično obstruktivno pljučno boleznijo. Za analizo podatkov sta bila poleg osnovne deskriptivne statistike uporabljena tudi hi-kvadrat test in ordinalna logistična regresija.Rezultati: V bolnišnični dokumentaciji so pacienti s kronično obstruktivno pljučno boleznijo imeli dokumentirana v povprečju manj kot 4 navodila o življenjskem slogu in samoobvladovanju bolezni (x = 3,8, s = 5,1). V odpustnem pismu je polovica pacientov (x = 0,5, s = 0,9) imela zabeleženih manj navodil o življenjskem slogu in samoobvladovanju bolezni kot v bolnišnični dokumentaciji (x2 = 33,455, p < 0,001). Diplomirane medicinske sestre so navodila dokumentirale petkrat pogosteje kot zdravniki.Diskusija in zaključek: Raziskava je za bolnišnično dokumentacijo pacientov s kronično obstruktivno pljučno boleznijo ugotovila nizko število dokumentiranih navodil o življenjskem slogu in samoobvladovanju bolezni. Treba bo povečati ozaveščenost o pomenu dokumentiranja zdravstvenovzgojnih navodil in oblikovati orodja za izboljšanje medpoklicne komunikacije.
