A Spanish adaptation of the Quality in Psychiatric Care-Inpatient (QPC-IP) instrument: Psychometric properties and factor structure.

BACKGROUND AND AIM: Western countries share an interest in evaluating and improving quality of care in the healthcare field. The aim was to develop and examine the psychometric properties and factor structure of the Spanish version of the Quality in Psychiatric Care-Inpatient (QPC-IP) instrument. METHODS: A psychometric study was conducted, translating the QPC-IPS instrument into Spanish, revision of the instrument by a panel of experts, and assessing its psychometric properties. 150 psychiatric inpatients completed the QPC-IP. Test-retest reliability was assessed by re-administering the questionnaire to 75 of these patients. RESULTS: After conducting pilot testing and a cognitive interview with 30 inpatients, it was determined that the QPC-IPS was adequate and could be self-administered. A Cronbach's alpha of 0.94 was obtained for the full instrument and values of 0.52-0.89 for the various dimensions of the questionnaire. Test re test reliability: The Intraclass Correlation Coefficient for the full questionnaire was 0.69, while for the individual dimensions values between 0.62 and 0.74 were obtained, indicating acceptable temporal stability. Convergent validity was analysed using 10-point numerical satisfaction scale, giving a positive correlation (0.49). Confirmatory factor analysis revealed six factors consistent with the original scale. The Spanish version yielded adequate results in terms of validity and reliability. CONCLUSION: Our findings provide evidence of the convergent validity, reliability, temporal stability and construct validity of the Spanish QPC-IP for measuring patient quality in psychiatric care in Spanish hospitals. Hospital administrators can use this tool to assess and identify areas for improvement to enhance quality in psychiatric care.

Factors related to the development of CMV-specific CD8+ T cell response in CMV-seropositive solid organ transplant candidates.

This cross-sectional study analyzes factors associated with the development of CMV-specific CD8+ response, measured by IFNg production after cytomegalovirus (CMV) peptide stimulation, in CMV-seropositive solid organ transplantation candidates. A total of 114 candidates were enrolled, of whom 22.8% (26/114) were nonreactive (IFNγ < 0.2 IU/mL). Multivariate logistic regression analysis showed that age, HLA alleles and organ to be transplanted were associated with developing CMV-specific CD8+ immunity (reactive; IFNγ ≥ 0.2 IU/mL). The probability of being reactive was higher in candidates over 50 than in those under 50 (OR 6.33, 95%CI 1.93-20.74). Candidates with HLA-A1 and/or HLA-A2 alleles had a higher probability of being reactive than those with non-HLA-A1/non-HLA-A2 alleles (OR 10.97, 95%CI 3.36-35.83). Renal candidates had a higher probability of being reactive than lung (adjusted OR 8.85, 95%CI 2.24-34.92) and liver candidates (OR 4.87, 95%CI 1.12-21.19). The AUC of this model was 0.84 (p < 0.001). Positive and negative predictive values were 84.8% and 76.9%, respectively. In renal candidates longer dialysis was associated with an increased frequency of reactive individuals (p = 0.040). Therefore, although the assessment of CMV-specific CD8+ response is recommended in all R+ candidates, it is essential in those with a lower probability of being reactive, such as non-renal candidates, candidates under 50 or those with non-HLA-A1/non-HLA-A2 alleles.

The relationship between burnout and empathy in physiotherapists: a cross-sectional study.

BACKGROUND: There have been few studies carried out into empathy in physiotherapists. Burnout can debilitate the quality of care and the efficacy of treatment as the empathetic capacity of the professional diminishes. OBJECTIVE: The objective of the study was to examine the association between the construct burnout, empathy and sociodemographic aspects in Spanish physiotherapists. METHODS: A cross-sectional electronic survey including the Maslach Burnout Inventory (for burnout assessment), the Interpersonal Reactivity Index (for empathy assessment) and sociodemographic data was answered by 461 Spanish physical therapists. A descriptive, bivariate and lineal regression analysis was performed. RESULTS: There was an association between burnout and empathy. Specifically, higher levels of burnout are associated with lower levels of empathy, whilst years of work experience is associated with lower levels of burnout. CONCLUSIONS: The results of this study contribute to a greater understanding of the relationship between the level of burnout and the dimensions of empathy in physiotherapists. The influence of burnout, which causes difficulties in the mobilization of the professional towards the establishment of a quality therapeutic relationship, is highlighted.KEY MESSAGESEmotional exhaustion is associated to greater personal discomfort and less empathy.The depersonalization is associated to personal discomfort and less empathy.Depersonalization is negatively associated to the lack of perspective.

Construction and content validation of a measurement tool to evaluate person-centered therapeutic relationships in physiotherapy services.

OBJECTIVES: This study sought to develop a tool for evaluating person-centered therapeutic relationships within physiotherapy services, and to examine the content validity of the same. METHODS: A mixed qualitative and quantitative study was performed in three distinct phases: 1) the items were generated based on a literature review and a content analysis of focus groups of patients and physiotherapists; 2) an e-Delphi survey process was performed based on three rounds to select and refine the proposed questionnaire; 3) two rounds of cognitive interviews were conducted to evaluate the comprehension of items, the clarity of language and the appropriateness and relevance of content. RESULTS: Thirty-one items were generated based on the seven domains identified after the analysis of four focus groups of physiotherapists and four patient focus groups. Nine experts participated in the e-Delphi survey. Fifty-five patients participated in the two rounds of the cognitive pre-tests. Participating patients were from public and private physical therapy services. Based on the participants' suggestions, four items were removed, and four were added, whereas 16 were reworded. CONCLUSIONS: The final tool comprised 31 items divided into seven domains. The response format was based on a 5-point Likert frequency scale. The response options ranged from "strongly agree" to "strongly disagree".

[Prognostic factors associated with postoperative complications in liver transplant]. / Factores pronósticos de complicaciones postoperatorias en el transplante hepático.

OBJECTIVES: the postoperative evolution of patients submitted to orthotopic liver transplant (OLT) is frequently associated with the appearance of different types of complications such as renal failure, graft rejection, infections, and neurological disorders. These complications are the most significant causes of early morbidity and mortality in patients undergoing OLT. The purpose of the present study was the identification of factors related to the different postoperative complications after OLT. EXPERIMENTAL DESIGN: a prospective study was carried out. PATIENTS: seventy-eight variables were analyzed in 32 consecutive patients undergoing OLT. The factors independently associated with the appearance of postoperative complications were identified using a stepwise logistic regression analysis. RESULTS: the multivariate analysis showed that malondialdehyde and creatinine pretransplant serum levels were associated with the development of renal dysfunction. The pretransplant levels of haemoglobin and the units of platelets administered during surgery were prognostic factors of infections. Acute graft rejection was predicted by ?-glutamyl transpeptidase and total bilirubin serum levels. The pretransplant sodium and glutaredoxin levels in serum were associated with neurological complications. CONCLUSIONS: we propose these markers for the identification of high-risk patients allowing an early surveillance and/or treatment to improve morbidity and survival in patients submitted to OLT.

[Digestive hemorrhage units. A national survey]. / Las unidades de hemorragias digestivas. Encuesta nacional.

The results of a national survey carried out on two hundred and five Spanish hospitals, on the treatment of upper gastrointestinal bleeding (UGIB) and special units for gastrointestinal haemorrhages, are reported in this paper. Questionnaires were sent to the chief of every Surgery, Gastroenterology and Internal Medicine Service. We received three hundred and twenty six answered questionnaires from 179 hospitals out of a total number of 582 mailed all over Spain. The Gastroenterology Units manage the UGIB in most hospitals, and in 45% of these, a protocol elaborated by gastroenterologists and surgeons is followed. In general, 94% of answers agree in the convenience or even need of Gastrointestinal Haemorrhage Units. However, when asked about this point in the setting of their own hospital, this figure comes down to 83%. On the other hand, only 46% consider the units to be warranted from the medical care and economical points of view. Most doctors think that to assess the yield of these units, medical care, economical and research criteria should be kept in mind. The general opinion is that should they exist in a given hospital, they should work as intermediate care units (87%), and be dependent of both Gastroenterology and Surgery units (71%). Currently, there are in Spain ten Gastrointestinal Haemorrhage Units, with a mean number of 6 beds, located in large hospitals, most of them run by the Gastroenterology Service. All of them are involved in some research project. In these units, overall mortality rates for UGIB, and mortality rate in bleeding peptic ulcers range close to 7% and 3%, respectively.

[Asymptomatic carriers of HBsAg: is a follow-up necessary?]. / Portadores asintomáticos del HBsAg: Es necesario su seguimiento?

We evaluated the clinical and epidemiological data of 142 HBsAg carriers. This prospective trial is part of a program of study and follow-up in HVB patients. The median age was 34.58 years old, males 56.3%. The average follow-up was 32.4 months. Complete clinical history, routine analysis, liver function tests, alfa-fetoprotein, serology for HVB, HCV and HDV and abdominal ecography were done in all patients. DNA-HVB was done only in special cases. Patients with less than 6 months of follow-up were excluded. The 118 remaining carriers were classified into two groups, depending on ALT values. Group 1 (normal ALT): included 98 carriers, 3 of them developed an active chronic hepatitis that was treated with interferon. A small CHC was diagnosed in another patient and it was resected. Group 2 (elevated ALT): included 20 carriers, only 9 of them agreed to biopsy and we found severe hepatic lesions in 4 of them. No group presented coinfection with HCV or HDV. No patient died. We conclude that the study and follow-up of asymptomatic HBsAg carriers permits an early diagnosis and treatment of the complications of this pathology (chronic hepatitis, CHC, etc); in our study, three patients developed chronic hepatitis, successfully treated with interferon, and one small size CHC was diagnosed in another patient. The study of relatives permits also detect subclinic liver disease and facilitates vaccination to prevention transmission of this infection.

Central obesity and altered peripheral adipose tissue gene expression characterize the NAFLD patient with insulin resistance: Role of nutrition and insulin challenge.

OBJECTIVE: Insulin resistance (IR) and white adipose tissue (WAT) dysfunction frequently are associated with nonalcoholic fatty liver disease (NAFLD); however, the pathogenic mechanisms contributing to their clustering are not well defined. The aim of this study was to define some nutritional, anthropometric, metabolic, and genetic mechanisms contributing to their clustering. METHODS: Forty-five (20 men, 25 women) patients (age 45.7 ± 11.1 y) with recent diagnosis of NAFLD were grouped according to IR state. Energy balance was assessed using a food questionnaire and indirect calorimetry, and body composition with anthropometry and dual-energy x-ray absorptiometry. Biochemical and hormonal parameters combined with adipose tissue gene expression were determined. Microarray analysis of gene expression was performed in a subset of WAT samples from IR patients (n = 9), in the fasted state, after specific test meals (monounsaturated fatty acid [MUFA], saturated fat [SAT], and carbohydrate-rich) and after being challenged with insulin. RESULTS: IR patients exhibited higher trunk fat to leg fat ratio (P < 0.05) and had a higher ratio of SAT/MUFA fat intake (P < 0.05) than insulin-sensitive (IS) individuals. Deposition of fat in the trunk but not in the leg was directly related to liver enzyme levels (P < 0.05). IR patients also had lower adiponectin serum levels and leptin (LEP) mRNA expression in WAT compared with IS patients (P < 0.01 and P < 0.05, respectively). Microarray analysis after insulin challenge confirmed that insulin treatment induces the expression of PPARG gene and LEP and decreases GCGR gene (P < 0.05 for all) in WAT. No changes in these genes were observed in the postprandial state induced after the acute effect of specific diets. CONCLUSIONS: Patients exhibiting NAFLD and IR had preferential central fat deposition directly related to their serum alanine aminotransferase levels. These patients showed peripheral adipose tissue dysfunction and exhibited inappropriately low LEP biosynthesis that could be partially restored after anabolic conditions induced by insulin signaling.

Determining hysteresis thresholds for edge detection by combining the advantages and disadvantages of thresholding methods.

Hysteresis is an important technique for edge detection, but the unsupervised determination of its parameters is not an easy problem. In this paper, we propose a method for unsupervised determination of hysteresis thresholds using the advantages and disadvantages of two thresholding methods. The basic idea of our method is to look for the best hysteresis thresholds in a set of candidates. First, the method finds a subset and a overset of the unknown edge points set. Then, it determines the best edge map with the measure chi(2). Compared with a general method to determine the parameters of an edge detector, our method performs well and is less computationally complex. The basic idea of our method can be generalized to other pattern recognition problems.
