Attitude towards drug therapy in a Community Mental Health Center evaluated by the Drug Attitude Inventory
Introduction: Negative attitude towards drug therapy can foster limited adherence to
treatment, which remains one of the biggest obstacles for implementing effective treatments,
especially long term.
Purposes: The purposes of the study were 1) to evaluate the attitude towards drug therapy
among a representative sample of patients treated in a community psychiatric service using
30-item Drug Attitude Inventory (DAI-30); 2) to evaluate the DAI-30 dimensions, applying
factorial analysis; and 3) to highlight the socio-demographic and clinical variables correlated
to DAI-30 score and factors.
Methods: The DAI was administered, over a 7-month period, to all patients treated in our
psychiatric outpatient services who agreed to participate in this study and provided their
informed consent. Data were statistically analyzed.
Results: With a response rate of 63.3%, 164 females and 136 males completed the DAI-30
with an average score of 14.24 (±10.46 SD), indicating moderately positive attitude towards
drug therapy. The analysis of DAI-30 internal consistency confirmed its reliability
(Cronbach’s alpha=0.84). Our factorial analysis highlighted three factors: Factor 1
(Cronbach’s alpha=0.81), composed of 7 items which indicate positive, trustful attitude;
Factor 2 (Cronbach’s alpha=0.78), composed of 5 items indicating negative attitude of
suspiciousness; and Factor 3 (Cronbach’s alpha=0.66), composed of 4 items suggesting
defensive and control attitude towards drug therapy.
Discussion: Among the selected variables, “monotherapy” and “total number of hospitalizations”
were negatively correlated to the final score of DAI-30, whereas being “married”
was positively correlated to it, in a statistically significant way, using the multiple linear
regression model. These correlations suggest that positive attitude towards drug therapy
could be reinforced by the condition of being married and reduced by relapses with
hospitalization, as literature highlighted, and, paradoxically, by a monotherapy, which
could suggest a sort of psychological dependence on therapy and, indirectly, on psychiatric
service, potentially correlated to the long-term treatments of our patients
ANÁLISE BIOCLIMÁTICA DO MUNICÍPIO DE CARAGUATATUBA DE SÃO PAULO DE 1998 A 2006
The northern shore of São Paulo state is a region with around 300 thousands inhabitants, having the tourism as major economic activity. The harbor of São Sebastião increased its arrival and departure capacity of over the last ten years and in Caraguatatuba a new natural gas exporting base will be implemented in 2007. As a function of all these changes and the increment of the tourism activity the urban environment experienced considerable growth. Furthermore, this region presents elevated values of air temperatures, over 25oC most part of the year, as well as elevated values of relative air humidity, over 80% due to the proximity of the atlantic forest remaining in the sea mountain range (Serra do Mar). The civil constructive system used in the region is based on masonry of clay bricks and ferroconcrete structures, inadequate to the climate. The objective of this work is to do a data survey of air temperature and relative humidity during the period from 1998 to 2006, and through the bioclimatic index of Givone, determine the strategies for civil construction in the region in order to preserve the thermal comfort and the energetic efficiency of the buildings. We intend to edit a brochure with the major results of this work so that it can be used to orient the professionals in the region related to civil construction and architecture.O litoral norte do estado de São Paulo é uma região com cerca de 300 mil habitantes, tendo como principal atividade econômica o turismo. O porto de São Sebastião aumentou sua capacidade de embarque nos últimos dez anos e em Caraguatatuba será implantada uma base de exploração de gás natural em 2007. Em função de todas estas mudanças e o incremento da atividade turística houve um crescimento acentuado do meio urbano. Além disso, esta região apresenta valores elevados da temperatura do ar, acima dos 250C na maior parte do ano, assim como da umidade relativa do ar, acima dos 80% devido à proximidade da mata atlântica ainda existente na serra do mar. O sistema construtivo utilizado na região é baseado na alvenaria de tijolos de barro e estrutura de concreto armado, inadequados ao clima. O objetivo deste trabalho é fazer um levantamento dos dados de temperatura do ar e de umidade relativa entre os anos de 1998 e 2006, e através das cartas bioclimáticas de Givone, determinar as estratégias construtivas para a região de maneira que o conforto térmico e a eficiência energética das edificações sejam preservados. Pretende-se editar uma cartilha contendo os principais resultados deste estudo e a mesma poderá servir de orientação aos profissionais da região ligados a engenharia e arquitetura
Chagas Disease and Heart Failure: An Expanding Issue Worldwide
Chagas disease, originally a South American endemic health problem, is expanding worldwide because of people migration. Its main impact is on the cardiovascular system, producing myocardial damage that frequently results in heart failure. Pathogenic pathways are mainly related to inmunoinflamatory reactions in the myocardium and, less frequently, in the gastrointestinal tract. The heart usually shows fibrosis, producing dilatation and damage of the electrogenic cardiac system. These changes result in cardiomyopathy with heart failure and frequent cardiac arrhythmias and heart blocks. Diagnosis of the disease must include a lab test to detect the parasite or its immune reactions and the usual techniques to evaluate cardiac function. Therapeutic management of Chagas heart failure does not differ significantly from the most common treatment for dilated cardiomyopathy, with special focus on arrhythmias and several degrees of heart block. Heart transplantation is reserved for end-stage cases. Major international scientific organisations are delivering recommendations for prevention and early diagnosis. This article provides an analysis of epidemiology, prevention, treatment and the relationship between Chagas disease and heart failure
High-Density Lipoprotein-Associated Paraoxonase-1 (PON-1) and Scavenger Receptor Class B Type 1 (SRB-1) in Coronary Artery Disease: Correlation with Disease Severity
background: coronary artery disease (CAD) is the leading cause of death worldwide. High-
density lipoprotein (HDL) is a well-established marker associated with CAD. the current research
goes beyond the conventional HDL-C measurement in previous studies and dives into the functional
intricacies of HDL. By understanding how HDL works, rather than just how much of it exists, we can
better tailor diagnostic and therapeutic strategies for CAD and related conditions. hence, the current
study quantifies the serum levels of two novel HDL-associated markers, paraoxonase-1 (PON-1) and
scavenger receptor class B Type 1 (SRB-1), in CAD cases vs. controls. methods: a total of 92 subjects,
including 69 CAD and 23 healthy controls, were included, based on the prevalence of the disease.
further, based on the severity of the disease, CAD cases were subcategorized as CAD-I, -II, and -III.
terum PON-1 and SRB-1 levels were measured and compared between patient and control groups.
results: the levels of PON-1 and SRB-1 (32.6 ng/mL and 12.49 ng/mL) were significantly lower in
CAD patients vs. the healthy control, at 60.36 ng/mL and 15.85 ng/mL, respectively (p < 0.000). a
further intergroup comparison showed a statistically significant difference between the CAT-I and
-III for PON-1 (p < 0.025), the CAT-I and -III, and CAT-II and -III for SRB-1 (p < 0.000). the receiver
operating characteristics (ROC) curve showed cutoff values of 48.20 ng/mL and 14.90 ng/mL for
PON-1 and SRB-1. conclusions: the current study found that serum levels of HDL-associated PON-1
and SRB-1 are significantly lower in CAD cases, and were also inversely related to the increasing
severity of coronary artery disease. this inference implies that serum PON-1 and SRB-1 could be
used as non-invasive tools for the identification of coronary atherosclerosis and risk assessment in
CAD cases
Toll-like receptor-4 is involved in hepatic fibrogenesis in the course of non-alcoholic fatty liver disease
Toll-like receptor-4 (TLR4) is actively involved in liver in the response to injury from a variety of etiologies. Recently TLR4 expression by hepatic progenitor cells (HPC) and biliary epithelial cells has been associated to the progression of liver damage in chronic HCV-related hepatitis (1). HPC compartment activation in ductular reaction (DR) is a feature of progressive disease also in non-alcoholic fatty liver disease (NAFLD) (2). We aimed to investigate the association among TLR4 expression, HPC compartment activation and histopathologic features of fibrotic disease progression in NAFLD. Seventy-four patients who had undergone liver biopsy were included and immunohistochemistry for TLR4 was performed on hepatic tissue samples. CK-7 was used to evaluate HPC, bile ducts (BD)/ductules of DR and intermediate hepatocytes; α-smooth muscle actin was used to quantify the activation of hepatic stellate cells (HSC) and of portal/septal myofibroblasts (MF). HPC in BD/DR were responsible for the highest TLR4 intensity of staining. TLR4-positive HPC and BD/ DR correlated with fibrosis (p<0.01 and p<0.05), activity of MF (p<0.001 and p<0.05) and HSC (p<0.001 and p<0.001), portal and interface chronic inflammation (p<0.01 and p=0.01). The present study indicates the activation of the TLR4 expressing HPC compartment as important determinant of the progressive liver damage in NAFLD. TLR4 stimulation could represent one of the mechanisms directly linking the activation of HPC to inflammation and fibrosis in NAFLD
Portal and interface chronic inflammation are associated with the progenitor cell compartment activation during NAFLD
Background and aim: During nonalcoholic fatty liver disease (NAFLD), portal and interface chronic inflammation (PCI and ICI) are strongly associated with fibrosis by activation of hepatic stellate cell (HSC)s (Brunt et al., 2009; Vespasiani-Gentilucci et al., 2014). However, the determinants of PCI and ICI observed in NAFLD remain to be elucidated. Since portal and periportal ductular reaction is related to disease progression, we aimed to investigate if PCI and ICI are associated with hepatic progenitor cell (HPC) compartment activation. Methods: Fifty-two NAFLD patients were studied. NAFLD activity score, fibrosis, PCI and ICI were histologically evaluated. HPCs, intermediate hepatobiliary cells and bile ductules/interlobular bile ducts were evaluated by immunohistochemistry for CK-7, CK-19 and EpCAM. HSC and myofibroblast (MF) activity were determined by immunohistochemistry for α-SMA. Results: PCI and ICI strongly correlated with HPC compartment activation and with the activity of MFs (p≤0.001). Lobular inflammation, ballooning and HPC compartment activation were all associated with both PCI (p<0.01) and ICI (p<0.05) by univariate analysis. In the multivariate models, HPC compartment activation was independently associated with PCI and ICI (OR 4.4, 1.7-11.5; OR 3.4, 1.5-7.9, respectively). Conclusions: During NAFLD, PCI and ICI are strongly associated with HPC compartment activation and this association is likely one determinant subtending the strong association between PCI/ICI and fibrosis
Reelin expression in liver and pancreas and its correlation with liver fibrosis
Reelin is an extracellular glycoprotein secreted by a variety of cell types in both embryonic and adult tissue and plays a critical role during brain development (1,2). Reelin is up-regulated in experimental liver cirrhosis of rats in hepatic stellate cell(HSC)s, the cell type mainly implicated in liver fibrogenesis, supporting that reelin is involved in the pathogenesis of liver fibrosis (3). Pancreatic stellate cell(PSC)s share similar morphology and function to HSCs, in pancreatic fibrosis setting (4). Currently, the role of reelin in human liver and pancreas is still unclear. We investigated reelin expression in different stages of chronic liver disease in 81 liver biopsies of HCV affected patients and in pancreatic tissue near to tumoral lesions. The expression of Reelin, HSC markers (CRBP1, alpha-SMA) and Dab1, a Reelin adaptor protein, was investigated by immunohistochemistry and immunofluorescence. Reelin protein was expressed by HSCs and a strong correlation was found between Reelin expression and liver fibrosis stage (
