Qualités psychométriques du Consumer satisfaction questionnaire (CSQ-8) et du Helping alliance questionnaire (HAQ) [Psychometric properties of the Consumer Satisfaction Questionnaire (CSQ-8) and the Helping Alliance Questionnaire (HAQ)].

BACKGROUND: This study was based on data from a quality of care assessment survey conducted in 2011 in outpatient polyclinics of the Vaud Canton in Switzerland, comprising questionnaires completed by 568 children over the age often and 672 parents of children of all ages. The objective of this study was to evaluate the psychometric qualities of the eight-item French versions for children of the Helping Alliance Questionnaire (HAQ) and the Consumer Satisfaction Questionnaire (CSQ-8) to allow formal validation and clinical application of these tools in the context of French-speaking child psychiatry. METHODOLOGY: Responses from children over the age often to the HAQ and CSQ-8 questionnaires were submitted to confirmatory factorial analysis (CFA) for ordinal data to verify their good fit with the original long versions. Construct validity (correspondence between scores on the scales and other external criteria considered to evaluate similar concepts) of the child questionnaires was tested by Spearman's correlation with the parents' responses and their feeling of being reassured or in agreement with respect to the first visit, and with the perception of the help provided by individual and family interviews. RESULTS: CFA showed an acceptable fit with the one-dimensional model of the original scales, both for the HAQ and the CSQ-8. Significant positive correlations of the scales with the parents' responses and with other convergent external criteria confirmed the good construct validity. CONCLUSIONS: These psychometric analyses provide a basis for the validation and clinical application of the abridged French versions of the HAQ and CSQ-8 in quality of care assessment in child psychiatry

Diagnostic pitfalls in the assessment of congenital hypopituitarism.

BACKGROUND: The diagnosis of congenital hypopituitarism is difficult and oftendelayed because its symptoms are nonspecific.AIM: To describe the different clinical presentations of children with congenitalhypopituitarism to reduce the time for diagnosis and to begin a precocious andappropriate treatment.STUDY DESIGN: We analyzed a cohort of five children with congenitalhypopituitarism, describing their clinical, biochemical and radiologicalcharacteristics from the birth to diagnosis.RESULTS: As first sign of the disease, all of five patients presented a neonatal hypoglycemia, associated in four cases with jaundice. In all these four cases,the clinicians hypothesized a metabolic disease delaying the diagnosis, which wasperformed in only two cases within the neonatal period. In the other three cases,the diagnosis was formulated at 2, 5 and 8 years of life because there was severeand precocious growth impairment.CONCLUSIONS: It is important to suspect congenital hypopituitarism in thepresence of persistent neonatal hypoglycemia associated with jaundice and of aprecocious and severe reduction of the growth velocity in childhood. In all thesecases, it is necessary to undertake a hypothalamic-pituitary magnetic resonanceimaging scan as soon as possible, and to start appropriate treatment

Obeticholic acid reduces biliary and hepatic matrix metalloproteinases activity in rat hepatic ischemia/reperfusion injury

Background We have previously shown that obeticholic acid (OCA) upregulates the biliary excretion of asymmetric dimethylarginine (ADMA), an inhibitor of iNOS regulating the activity of matrix metalloproteinases (MMPs). Here, the effects of OCA on MMP-2 and MMP-9 activity in liver, bile and serum were evaluated after hepatic ischemia/reperfusion (I/R) injury. Material and methods Male Wistar rats (n = 20) were orally administered 10 mg/kg/day of OCA (5 days) and subjected to a 60-min ischemia and 60-min reperfusion. Bile, serum and tissue were collected for MMP-2 and MMP-9 activity quantification. The MMP regulator tissue reversion-inducing cysteine rich protein with Kazal motifs (RECK), tissue inhibitor of metalloproteinases (TIMPs), iNOS and biliary levels of LDH, γGT, glucose and ADMA were quantified. Results In the I/R group, OCA administration reduced MMP-2 and MMP-9 in liver, bile and serum. A downregulation of tissue RECK and TIMPs, observed under I/R, were recovered by OCA. Immunohistochemical staining of hepatic tissue demonstrated that RECK expression is mainly localized in both cholangiocytes and hepatocytes. Hepatic iNOS positively correlated with tissue MMP-2 and MMP-9 activity. Biliary levels of LDH, γGT and glucose were lower in I/R rats treated with OCA; in bile, MMP levels positively correlated with LDH and γGT. Conclusion Thus, OCA administration confers protection to cholangiocytes via downregulation of biliary MMPs in livers submitted to I/R. This event is associated with hepatic RECK- and TIMP-mediated MMP decrease

Matrix metalloprotease activity is enhanced in the compensated but not in the decompensated phase of pressure overload hypertrophy

BACKGROUND: During the transition of pressure overload hypertrophy (POH) to heart failure (HF) there is intense interstitial cardiac remodeling, characterized by a complex balance between collagen deposition and degradation by matrix metalloproteases (MMPs). This study was aimed at investigating the process of cardiac remodeling during the different phases of the transition of POH to HF. METHODS: Guinea pigs underwent thoracic descending aortic banding or sham operation. Twelve weeks after surgery, left-ventricular (LV) end-diastolic internal dimension and ventricular systolic pressure were measured by combined M-mode echocardiography and micromanometer cathetherization. The MMP activity, tissue-specific MMP inhibitors (TIMPs), and collagen fraction were evaluated in LV tissue samples by zymography, ELISA, and computer-aided analysis, respectively. RESULTS: Banded animals were divided by lung weight values into either compensated left-ventricular hypertrophy (LVH) or HF groups, as compared with sham-operated controls. All HF animals exhibited a restrictive pattern of Doppler transmitral inflow, indicative of diastolic dysfunction, and developed lung congestion. Compensated LVH was associated with increased MMP-2 activity, which was blunted after transition to HF, at a time when TIMP-2 levels and collagen deposition were increased. CONCLUSIONS: The cardiac remodeling process that accompanies the development of POH is a phase-dependent process associated with progressive deterioration of cardiac function

Risk perception and affective state on work exhaustion in obstetrics during the COVID-19 pandemic

A multicenter cross-sectional survey study involving four Italian University Hospitals was performed to test the hypothesis that negative affect and positive affect (affective dimensions) mediate the association between risk perception (perceived risk of infection and death; cognitive dimensions) and the feeling of work exhaustion (WE) among obstetrics healthcare providers (HCPs) during the Coronavirus Disease 2019 (COVID-19) pandemic. Totally, 570 obstetrics HCPs were invited to complete the 104-item IPSICO survey in May 2020. A theoretical model built on the tested hypothesis was investigated by structural equation modelling. The model explained 32.2% of the WE variance. Only negative affect mediated the association between cognitive dimensions and WE and also the association between WE and psychological well-being before the pandemic, experiences of stressful events, female gender, and dysfunctional coping. Non-mediated associations with WE were observed for work perceived as a duty, experience of stressful events, support received by colleagues, and the shift strategy. Only previous psychological well-being, support by colleagues, and shift strategies were inversely associated with WE. Based on study results, monitoring negative than positive affect appears superior in predicting WE, with practical implications for planning psychological interventions in HCPs at the individual, interpersonal, and organizational levels
