Poly-N-acetyl glucosamine nanofibers for negative-pressure wound therapies.

The wound healing promoting effect of negative wound pressure therapies (NPWT) takes place at the wound interface. The use of bioactive substances at this site represents a major research area for the development of future NPWT therapies. To assess wound healing kinetics in pressure ulcers treated by NPWT with or without the use of a thin interface membrane consisting of poly-N-acetyl glucosamine nanofibers (sNAG) a prospective randomized clinical trial was performed. The safety of the combination of NPWT and sNAG was also assessed in patients treated with antiplatelet drugs. In the performed study, the combination of NPWT and sNAG in 10 patients compared to NPWT alone in 10 patients promoted wound healing due to an improved contraction of the wound margins (p = 0.05) without a change in wound epithelization. In 6 patients treated with antiplatelet drugs no increased wound bleeding was observed in patients treated by NPWT and sNAG. In conclusion, the application of thin membranes of sNAG nanofibers at the wound interface using NPWT was safe and augmented the action of NPWT leading to improved wound healing due to a stimulation of wound contraction.

Validity of the FACIT-Sp to assess spiritual well-being in elderly patients

Among instruments measuring spiritual well-being, the Functional Assessment of Chronic Illness Therapy-Spiritual well-being (FACIT-Sp-12) is the most widely used instrument in research. It has been validated in patients suffering from cancer or HIV/AIDS, but has rarely been used in elderly patients. The objectives of this study were to determine the psychometric properties and suitability of the FACIT-Spto assess spiritual well-being in hospitalized elderly patients. This cross-sectional study uses a mixed method approach. Subjects were patients (N = 208), aged 65 years and older, consecutively admitted in post-acute rehabilitation. Psychometric properties of the FACITSp were investigated. The internal structure of the FACIT-Sp (factor structure and internal consistency) was assessed. Convergent validity of the FACIT-Sp was assessed using the Spiritual Distress Assessment Tool (SDAT), the question "Are you at peace?" and the Geriatric Depression Scale (GDS). Predictive validity was assessed using length of stay (LOS) and discharge destination. Understanding and interpretation of FACIT-Sp items were consecutively assessed in a sub-sample of 135 patients. Results show that FACIT-Sp scores ranged from 7 to 46 (mean 29.6 ± 7.8); 23.1% of the patients had high spiritual well-being. Cronbach's α was g ood ( 0.85). Item-to-total correlations were all significant (0.34 to 0.73). Principal component analyses performed with 2 or 3 factors were only moderately consistent with previous work. FACIT-Sp correlated with SDAT, "Are you at peace?" and GDS (Rho = −0.45, P < 0.001; 0.51, P < 0.001 and −0.38, P < 0.001). No association was found with LOS or discharge destination. Spontaneous comments about one or more FACIT-Sp items were made by 97/135 (71.9%). Specifically, items that address purpose and meaning in life were frequently found difficult to answer. Analyses suggest that the FACIT-Sp may underestimate spiritual well-being in older patients. In conclusion, despite having acceptable psychometric properties, the FACIT-Sp presents limitations for measurement of spiritual well-being in hospitalized elderly patients.

Use of alternative and complementary therapies in labor and delivery care: a cross-sectional study of midwives" training in Catalan hospitals accredited as centers for normal birth

Background: The use of complementary and alternative medicine (CAM) and complementary and alternative therapies (CAT) during pregnancy is increasing. Scientific evidence for CAM and CAT in the field of obstetrics mainly covers pain relief in labor. Midwives are responsible for labor and delivery care: hence, their knowledge of CAM and CAT is important. The aims of this study are to describe the professional profile of midwives who provide care for natural childbirth in Catalan hospitals accredited as centers for normal birth, to assess midwives" level of training in CAT and their use of these therapies, and to identify specific resources for CAT in labor wards. Methods: A descriptive, cross-sectional, quantitative method was used to assess the level of training and use of CAT by midwives working at 28 hospitals in Catalonia, Spain, accredited as public normal birth centers. Results: Just under a third of midwives (30.4%) trained in CAT after completion of basic training. They trained in an average of 5.97 therapies (SD 3.56). The number of CAT in which the midwives were trained correlated negatively with age (r = - 0.284; p < 0.001) and with their time working at the hospital in years (r = - 0.136; p = 0.036). Midwives trained in CAT considered that the following therapies were useful or very useful for pain relief during labor and delivery: relaxation techniques (64.3%), hydrotherapy (84.8%) and the application of compresses to the perineum (75.9%). The availability of resources for providing CAT during normal birth care varied widely from center to center. Conclusions: Age may influence attitudes towards training. It is important to increase the number of midwives trained in CAM for pain relief during childbirth, in order to promote the use of CAT and ensure efficiency and safety. CAT resources at accredited hospitals providing normal childbirth care should also be standardized.

Attachment and spiritual coping in patients with chronic schizophrenia

Many studies on spirituality in psychosis have shown that, compared to a nonclinical population, patients make more use of spiritual beliefs/religious practices to deal with their problems. Our research question was to test whether attachment to spiritual figures could be a good explanation for religious coping strategies in patients with psychosis. First, adult attachment was investigated in 28 patients with chronic psychosis and 18 controls, using the Adult Attachment Interview. Diagnostic evaluations were performed with the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders (4th edition, Text Revision) Axis I disorders and symptomatic evaluation with the Brief Psychiatric Rating Scale. Results also show a high prevalence of insecure avoidant attachment in patients, and suggest that a significant part of religious coping might be explained by the theory of attachment (64% of the patients, 78% of controls). The implications of these results are interpreted in light of correspondence and compensation hypotheses.

Salvador Dalí: a spiritual gaze

There is a tendency to overlook the many fields that attracted Salvador Dalí, one of the most controversial figures of the 20th century. The Catalan artist was interested in painting, sculpture, engraving, opera, literature, advertising, dance, and even the theatre of life. Dalí was also a theoretician, constantly examining the processes of creation and knowledge: over the years he developed an imagery which, though changing, remained coherent, giving his body of work an unexpected unity.

Arterial Therapies of Non-Colorectal Liver Metastases.

BACKGROUND: The unique situation of the liver with arterial and venous blood supply and the dependency of the tumor on the arterial blood flow make this organ an ideal target for intrahepatic catheter-based therapies. Main forms of treatment are classical bland embolization (TAE) cutting the blood flow to the tumors, chemoembolization (TACE) inducing high chemotherapy concentration in tumors, and radioembolization (TARE) without embolizing effect but very high local radiation. These different forms of therapies are used in different centers with different protocols. This overview summarizes the different forms of treatment, their indications and protocols, possible side effects, and available data in patients with non-colorectal liver tumors. METHODS: A research in PubMed was performed. Mainly clinical controlled trials were reviewed. The search terms were 'embolization liver', 'TAE', 'chemoembolization liver', 'TACE', 'radioembolization liver', and 'TARE' as well as 'chemosaturation' and 'TACP' in the indications 'breast cancer', 'neuroendocrine', and 'melanoma'. All reported studies were analyzed for impact and reported according to their clinical relevance. RESULTS: The main search criteria revealed the following results: 'embolization liver + breast cancer', 122 results, subgroup clinical trials 16; 'chemoembolization liver + breast cancer', 62 results, subgroup clinical trials 11; 'radioembolization liver + breast cancer', 37 results, subgroup clinical trials 3; 'embolization liver + neuroendocrine', 283 results, subgroup clinical trials 20; 'chemoembolization liver + neuroendocrine', 202 results, subgroup clinical trials 9; 'radioembolization liver + neuroendocrine', 64 results, subgroup clinical trials 9; 'embolization liver + melanoma', 79 results, subgroup clinical trials 15; 'chemoembolization liver + melanoma', 60 results, subgroup clinical trials 14; 'radioembolization liver + melanoma', 18 results, subgroup clinical trials 3. The term 'chemosaturation liver' was tested without indication since only few publications exist and provided us with five results and only one clinical trial. CONCLUSION: Despite many years of clinical use and documented efficacy on intra-arterial treatments of the liver, there are still only a few prospective multicenter trials with many different protocols. To guarantee the future use of these efficacious therapies, especially in the light of many systemic or surgical therapies in the treatment of non-colorectal liver metastases, further large randomized trials and transparent guidelines need to be established.

Attachment and coping in psychosis in relation to spiritual figures

Background: Studies have found higher levels of insecure attachment in individuals with schizophrenia. Attachment theory provides a framework necessary for conceptualizing the development of interpersonal functioning. Some aspects of the attachment of the believer to his/her spiritual figure are similar to those between the child and his/her parents. The correspondence hypothesis suggests that early child-parent interactions correspond to a person's relation to a spiritual figure. The compensation hypothesis suggests that an insecure attachment history would lead to a strong religiousness/spirituality as a compensation for the lack of felt security. The aim of this study is to explore attachment models in psychosis vs. healthy controls, the relationships between attachment and psychopathology and the attachment processes related to spiritual figures. Methods: Attachment models were measured in 30 patients with psychosis and 18 controls with the AAI (Adult Attachment interview) in relationship with psychopathology. Beliefs and practices related to a spiritual figure were investigated by qualitative and quantitative analyses. Results: Patients with psychosis showed a high prevalence of insecure avoidant attachment. Spiritual entities functioned like attachment figures in two thirds of cases. Interviews revealed the transformation of internal working models within relation to a spiritual figure: a compensation process was found in 7 of the 32 subjects who showed a significant attachment to a spiritual figure. Conclusions: Attachment theory allows us to highlight one of the underlying dimensions of spiritual coping in patients with psychosis.

Successful therapies for Alzheimer's disease: why so many in animal models and none in humans?

Peering into the field of Alzheimer's disease (AD), the outsider realizes that many of the therapeutic strategies tested (in animal models) have been successful. One also may notice that there is a deficit in translational research, i.e., to take a successful drug in mice and translate it to the patient. Efforts are still focused on novel projects to expand the therapeutic arsenal to 'cure mice.' Scientific reasons behind so many successful strategies are not obvious. This article aims to review the current approaches to combat AD and to open a debate on common mechanisms of cognitive enhancement and neuroprotection. In short, either the rodent models are not good and should be discontinued, or we should extract the most useful information from those models. An example of a question that may be debated for the advancement in AD therapy is: In addition to reducing amyloid and tau pathologies, would it be necessary to boost synaptic strength and cognition? The debate could provide clues to turn around the current negative output in generating effective drugs for patients. Furthermore, discovery of biomarkers in human body fluids, and a clear distinction between cognitive enhancers and disease modifying strategies, should be instrumental for advancing in anti-AD drug discovery.

Imaging of Tumour Microenvironment for the Planning of Oncological Therapies Using Positron Emission Tomography

Tumour cells differ from normal tissue cells in several important ways. These differences, like for example changed energy metabolism, result in altered microenvironment of malignant tumours. Non-invasive imaging of tumour microenvironment has been at the centre of intense research recently due to the important role that this changed environement plays in the development of malignant tumours and due to the role it plays in the treatment of these tumours. In this respect, perhaps the most important characteristics of the tumour microenvironment from this point of view are the lack of oxygen or hypoxia and changes in blood flow (BF). The purpose of this thesis was to investigate the processes of energy metabolism, BF and oxygenation in head and neck cancer and pancreatic tumours and to explore the possibilities of improving the methods for their quantification using positron emission tomography (PET). To this end [18F]EF5, a new PET tracer for detection of tumour hypoxia was investigated. Favourable uptake properties of the tracer were observed. In addition, it was established that the uptake of this tracer does not correlate with the uptake of existing tracers for the imaging of energy metabolism and BF, so the information about the presence of tissue hypoxia cannot therefore be obtained using tracers such as [18F]FDG or [15O]H2O. These results were complemented by the results of the follow-up study in which it was shown that the uptake of [18F]EF5 in head and neck tumours prior to treatment is also associated with the overall survival of the patients, indicating that tumour hypoxia is a negative prognostic factor and might be associated with therapeutic resistance. The influences of energy metabolism and BF on the survival of patients with pancreatic cancer were investigated in the second study. The results indicate that the best predictor of survival of patients with pancreatic cancer is the relationship between energy metabolism and BF. These results suggest that the cells with high metabolic activity in a hypoperfused tissue have the most aggressive phenotype.

Spiritual Gifts according to C. Peter Wagner

Nådegåvorna eller de andliga gåvorna är en betydande drivkraft hos en del kristna församlingar. Lekmän attraheras till församlingar i ökande grad av nådegåvornas dragkraft och detta är en global trend. C. Peter Wagner som tidigare arbetat som professor vid Fuller Theological Seminary har skrivit ovanligt många publikationer, både akademiska och allmänna, som behandlar nådegåvor. Han representerar den neokarismatiska kristendomen och den så kallade nya apostoliska reformationen. Jag har undersökt strukturer och grundläggande principer i Wagners tänkande. En central fråga i avhandlingen är att dryfta vilka styrkor och svagheter som kan påvisas i hans uppfattning om församlingslivet. En ytterligare målsättning är att hitta länkar mellan nådegåvorna och församlingens tillväxt. Vidare har jag undersökt förhållandet mellan den neokarismatiska kristendomen och den nya apostoliska reformationen till tidigare karismatiska rörelser, till exempel till neopentekostalismen och den klassiska pentekostalismen? I denna avhandling kommer dessa frågor och några andra att diskuteras. Kännetecknande för Wagners församlingslära är att han kombinerar metoder och element från businessvärlden och kristliga tron. Avhandlingen presenterar de centrala elementen i Wagners teologi. Wagner har tidigare karakteriserats av klart evangelikalt tänkande. Hans teologi har dock under senare år utvecklats i karismatisk riktning. Hans senare produktion tar upp bl.a. sådana teman som postmillennial eskatologi. Wagner uppskattar grunderna i den klassiska pentekostalismen men vidareutvecklar många läror. Hans tänkande skiljer sig från den klassiska pentekostalismen bl.a. i det att han ser likheter mellan nådegåvorna och de naturliga begåvningarna. Den kraftiga betoningen av apostelns funktion och den hierarki som detta medför i församlingen har väckt anstöt hos somliga ledare i den klassiska pingströrelsen. Wagern anser, i motsats till den klassiska pingströrelsens syn, att en kristen människa kan vara besatt av onda andar. Wagner indelar nådegåvorna i två olika viktiga kategorier. Till de för församlingen centrala nådegåvorna hör de apostoliska och profetiska nådegåvorna som tillsammans utgör de grundläggande gåvorna. Vidare betonar han betydelsen av ledarskap och trons nådegåva samt den så kallade "power evangelism", som omfattar övertygande evangelisation, helande och under. Vidare betonar Wagner vikten av de nådegåvor som behövs vid andlig krigföring: förmågan att skilja mellan olika andar, frigöring från unda andar och förbön. De nådegåvor som har med tjänande och själavård att göra får en mer perifer plats i hans tänkande. De andliga gåvor som befrämjar församlingens tillväxt och förkristnande av samhället betraktas som de viktigaste. Wagners teologi nyanseras ytterligare av kopplingar till postmillenial rekonstruktivism, den så kallade "Kingdom Now" teologin och rörelsen Word of Faith. Wagerns postmilleniala syn förpliktar de kristina att anta en aktiv roll vid förverkligandet av Guds rike på jorden före parusi. Wagner har fått kritik för det att han ger kristendomen marknadsekonomiska drag. Dessa element kommer till synes i bl.a. i hans tanke om att Gud belönar de kristna med förmögenhet som tas från de icke-kristna. Wagners ställning som teolog är omdiskuterad. Han förbinder sig vid den kristna tronbekännelsen och är på sitt sätt bibeltrogen, men de animistiska dragen och kapitalismens inflytande i hans teologi gör honom till en omstridd person.
