Disseny d'un protocol objectiu de valoració clínica amb pacients amb Trastorn per Afartament (TA)

En aquest treball es pretén dissenyar un protocol de valoració clínica objectiu del Trastorn per Afartament (TA). Per dur-lo a terme, hem començat per delimitar els símptomes dels Trastorns de la Conducta Alimentària (TCA). Seguidament hem revisat la literatura i les investigacions sobre el trastorn. Per poder explicar les característiques més importants, les hem dividit en tres apartats, nosologia, prevalença i factors de risc. Arrel dels factors psicològics i psicopatològics, més transcendents en la gènesis clínica i l’evolució dels Trastorns de la Conducta Alimentària (TCA) hem valorat quins instruments, són més útils per valorar aquesta patologia, detectant els factors psicològics més rellevants en la definició i l’evolució vital del trastorn. Finalment els hem descrit i comparat amb els altres instruments més utilitzats per valorar la patologia alimentària.

Impact of a pain protocol including hypnosis in major burns.

BACKGROUND: Pain is a major issue after burns even when large doses of opioids are prescribed. The study focused on the impact of a pain protocol using hypnosis on pain intensity, anxiety, clinical course, and costs. METHODS: All patients admitted to the ICU, aged >18 years, with an ICU stay >24h, accepting to try hypnosis, and treated according to standardized pain protocol were included. Pain was scaled on the Visual Analog Scale (VAS) (mean of daily multiple recordings), and basal and procedural opioid doses were recorded. Clinical outcome and economical data were retrieved from hospital charts and information system, respectively. Treated patients were matched with controls for sex, age, and the burned surface area. FINDINGS: Forty patients were admitted from 2006 to 2007: 17 met exclusion criteria, leaving 23 patients, who were matched with 23 historical controls. Altogether patients were 36+/-14 years old and burned 27+/-15%BSA. The first hypnosis session was performed after a median of 9 days. The protocol resulted in the early delivery of higher opioid doses/24h (p<0.0001) followed by a later reduction with lower pain scores (p<0.0001), less procedural related anxiety, less procedures under anaesthesia, reduced total grafting requirements (p=0.014), and lower hospital costs per patient. CONCLUSION: A pain protocol including hypnosis reduced pain intensity, improved opioid efficiency, reduced anxiety, improved wound outcome while reducing costs. The protocol guided use of opioids improved patient care without side effects, while hypnosis had significant psychological benefits.

Engineering, conjugation, and immunogenicity assessment of Escherichia coli O121 O antigen for its potential use as a typhoid vaccine component.

State-of-the-art production technologies for conjugate vaccines are complex, multi-step processes. An alternative approach to produce glycoconjugates is based on the bacterial N-linked protein glycosylation system first described in Campylobacter jejuni. The C. jejuni N-glycosylation system has been successfully transferred into Escherichia coli, enabling in vivo production of customized recombinant glycoproteins. However, some antigenic bacterial cell surface polysaccharides, like the Vi antigen of Salmonella enterica serovar Typhi, have not been reported to be accessible to the bacterial oligosaccharyltransferase PglB, hence hamper development of novel conjugate vaccines against typhoid fever. In this report, Vi-like polysaccharide structures that can be transferred by PglB were evaluated as typhoid vaccine components. A polysaccharide fulfilling these requirements was found in Escherichia coli serovar O121. Inactivation of the E. coli O121 O antigen cluster encoded gene wbqG resulted in expression of O polysaccharides reactive with antibodies raised against the Vi antigen. The structure of the recombinantly expressed mutant O polysaccharide was elucidated using a novel HPLC and mass spectrometry based method for purified undecaprenyl pyrophosphate (Und-PP) linked glycans, and the presence of epitopes also found in the Vi antigen was confirmed. The mutant O antigen structure was transferred to acceptor proteins using the bacterial N-glycosylation system, and immunogenicity of the resulting conjugates was evaluated in mice. The conjugate-induced antibodies reacted in an enzyme-linked immunosorbent assay with E. coli O121 LPS. One animal developed a significant rise in serum immunoglobulin anti-Vi titer upon immunization.

Cervical screening programme: HPV triage and test of cure protocol

Testing for high-risk human papillomavirus (HR-HPV) as triage and test of cure was introduced into the Northern Ireland Cervical Screening Programme on Monday 28 January 2013. This policy change will significantly alter the screening pathway for women with a mild dyskaryosis or borderline smear result. The link between HR-HPV infection and the development of cervical cancer has now been clearly established, with almost 100% of cervical cancers containing HPV DNA. Women with no evidence of HR-HPV infection are extremely unlikely to develop cervical cancer in the short to medium term. HPV triage is the process whereby HR-HPV testing is used to manage women with low grade cervical abnormalities. Only 15-20% of women with a borderline or mild smear result have a significant abnormality that needs treatment. HR-HPV testing is effective in identifying which women may need treatment and allows colposcopy resources to be allocated more effectively.The test of cure process is being introduced because it is now known that women with a normal or low grade smear test, and who are HR-HPV negative at six months after treatment, are at very low risk of residual disease. These women do not need to be recalled for another screening appointment for three years.The test of cure process means all post-treatment smears (at six months) that are reported as normal, borderline or mild dyskaryosis will be tested for HR-HPV. Those women who are HR-HPV positive will remain at colposcopy. HR-HPV negative women can be safely returned to recall in three years. It is estimated that the HR-HPV test of cure will allow approximately 80% of women who have been through treatment to avoid undergoing annual smear tests. This flowchart poster outlines the new triage and test of cure process. It was distributed to all GPs in Northern Ireland and is available to download as a PDF from this website.�

Elaboració d'un protocol basat en XML per a una xarxa de sensors

La progressiva reducció de dimensió i cost en els dispositius electrònics, la dràstica retallada de consum elèctric i la independència de què això els dota han fet créixer en els últims temps l'interès de les comunitats científiques i tecnològiques per les xarxes sense fils de petits dispositius. Per altra banda, l'XML (eXtensible Markup Language) és un metallenguatge extensible que ha esdevingut un estàndard per a l'intercanvi d'informació estructurada entre diferents plataformes. L'objectiu d'aquest treball és explorar les possibilitats que pot oferir la introducció de l'XML en les xarxes de sensors amb l'elaboració d'un protocol de comunicació basat en aquest llenguatge i demostrar la transparència en el canvi de plataforma. Per fer-ho, es disposa de dos dispositius amb capacitat de comunicació sense fils equipats amb detectors de temperatura, lluminositat, efecte Hall i nivell de càrrega de la bateria. El projecte constarà de dues parts: una, més extensa, dedicada al desenvolupament del programari per a aquests dispositius, encarregat de obtenir les lectures dels diferents sensors i emetre-les per la xarxa utilitzant el llenguatge XML, i una altra, per recollir aquesta informació present a la xarxa, interpretar-la, salvar-la en una base de dades i exposar-la al món en una plana web. El programari dels dispositius sensors s'escriurà en llenguatge nesC dins el sistema tinyOS que és el sistema operatiu que equipen. La part d'explotació de les dades es desenvoluparà sota la plataforma .NET de Microsoft.

Histological and histochemical evaluation of human oral mucosa constructs developed by tissue engineering

Reconstruction of large oral mucosa defects is often challenging, since the shortage of healthy oral mucosa to replace the excised tissues is very common. In this context, tissue engineering techniques may provide a source of autologous tissues available for transplant in these patients. In this work, we developed a new model of artificial oral mucosa generated by tissue engineering using a fibrin-agarose scaffold. For that purpose, we generated primary cultures of human oral mucosa fibroblasts and keratinocytes from small biopsies of normal oral mucosa using enzymatic treatments. Then we determined the viability of the cultured cells by electron probe quantitative X-ray microanalysis, and we demonstrated that most of the cells in the primary cultures were alive and had high K/Na ratios. Once cell viability was determined, we used the cultured fibroblasts and keratinocytes to develop an artificial oral mucosa construct by using a fibrin-agarose extracellular matrix and a sequential culture technique using porous culture inserts. Histological analysis of the artificial tissues showed high similarities with normal oral mucosa controls. The epithelium of the oral substitutes had several layers, with desmosomes and apical microvilli and microplicae. Both the controls and the oral mucosa substitutes showed high suprabasal expression of cytokeratin 13 and low expression of cytokeratin 10. All these results suggest that our model of oral mucosa using fibrin-agarose scaffolds show several similarities with native human oral mucosa.

Alternative PCR protocol using a single primer set for assessing DNA quality in several tissues from a large variety of mammalian species living in areas endemic for leishmaniasis

The aim of this work was to establish a modified pre-diagnostic polymerase chain reaction (PCR) protocol using a single primer set that enables successful amplification of a highly conserved mammalian sequence in order to determine overall sample DNA quality for multiple mammalian species that inhabit areas endemic for leishmaniasis. The gene encoding interphotoreceptor retinoid-binding protein (IRBP), but not other conserved genes, was efficiently amplified in DNA samples from tail skin, ear skin, bone marrow, liver and spleen from all of the species tested. In tissue samples that were PCR-positive for Leishmania, we found that DNA from 100%, 55% and 22% of the samples tested resulted in a positive PCR reaction for the IRBP, beta-actin and beta-globin genes, respectively. Nucleotide sequencing of an IRBP amplicon resolved any questions regarding the taxonomical classification of a rodent, which was previously based simply on the morphological features of the animal. Therefore, PCR amplification and analysis of the IRBP amplicon are suitable for pre-diagnostically assessing DNA quality and identifying mammalian species living in areas endemic to leishmaniasis and other diseases.

An experimental protocol for the establishment of dogs with long-term cellular immune reactions to Leishmania antigens

Domestic dogs are considered to be the main reservoirs of zoonotic visceral leishmaniasis. In this work, we evaluated a protocol to induce Leishmania infantum/Leishmania chagasi-specific cellular and humoral immune responses in dogs, which consisted of two injections of Leishmania promastigote lysate followed by a subcutaneous inoculation of viable promastigotes. The primary objective was to establish a canine experimental model to provide positive controls for testing immune responses to Leishmania in laboratory conditions. After inoculation of viable promastigotes, specific proliferative responses of peripheral blood mononuclear cells (PBMCs) to either Leishmania lysate or recombinant proteins, the in vitro production of interferon-γ by antigen-stimulated PBMCs and a significant increase in circulating levels of anti-Leishmania antibodies were observed. The immunized dogs also displayed positive delayed-type hypersensitivity reactions to Leishmania crude antigens and to purified recombinant proteins. An important finding that supports the suitability of the dogs as positive controls is that they remained healthy for the entire observation period, i.e., more than seven years after infection. Following the Leishmania antigen lysate injections, the infection of dogs by the subcutaneous route appears to induce a sustained cellular immune response, leading to an asymptomatic infection. This provides a useful model for both the selection of immunogenic Leishmania antigens and for immunobiological studies on their possible immunoprotective activities.

Cost-effectiveness of the implementation of an enhanced recovery protocol for colorectal surgery.

BACKGROUND: Enhanced recovery protocols may reduce postoperative complications and length of hospital stay. However, the implementation of these protocols requires time and financial investment. This study evaluated the cost-effectiveness of enhanced recovery implementation. METHODS: The first 50 consecutive patients treated during implementation of an enhanced recovery programme were compared with 50 consecutive patients treated in the year before its introduction. The enhanced recovery protocol principally implemented preoperative counselling, reduced preoperative fasting, preoperative carbohydrate loading, avoidance of premedication, optimized fluid balance, standardized postoperative analgesia, use of a no-drain policy, as well as early nutrition and mobilization. Length of stay, readmissions and complications within 30 days were compared. A cost-minimization analysis was performed. RESULTS: Hospital stay was significantly shorter in the enhanced recovery group: median 7 (interquartile range 5-12) versus 10 (7-18) days (P = 0·003); two patients were readmitted in each group. The rate of severe complications was lower in the enhanced recovery group (12 versus 20 per cent), but there was no difference in overall morbidity. The mean saving per patient in the enhanced recovery group was euro1651. CONCLUSION: Enhanced recovery is cost-effective, with savings evident even in the initial implementation period.
