RESUMO

BACKGROUND: Childhood obesity is a complex disease resulting from the interaction of multiple factors. The effective management of childhood obesity requires assessing the psychosocial and lifestyle factors that may play a role in the development and maintenance of obesity. This study centers on available scientific literature on psychosocial and lifestyle assessments for childhood obesity, and experiences and views of healthcare professionals with regard to assessing psychosocial and lifestyle factors within Dutch integrated care. METHODS: Two methods were used. First, a scoping review (in PubMed, Embase, PsycInfo, IBSS, Scopus and Web of Science) was performed by systematically searching for scientific literature on psychosocial and lifestyle assessments for childhood obesity. Data were analysed by extracting data in Microsoft Excel. Second, focus group discussions were held with healthcare professionals from a variety of disciplines and domains to explore their experiences and views about assessing psychosocial and lifestyle factors within Dutch integrated care. Data were analysed using template analysis, complemented with open coding in MAXQDA. RESULTS: The results provide an overview of relevant psychosocial and lifestyle factors that should be assessed and were classified as child, family, parental and lifestyle (e.g. nutrition, physical activity and sleep factors) and structured into psychological and social aspects. Insights into how to assess psychosocial and lifestyle factors were identified as well, including talking about psychosocial factors, lifestyle and weight; the professional-patient relationship; and attitudes of healthcare professionals. CONCLUSIONS: This study provides an overview of psychosocial and lifestyle factors that should be identified within the context of childhood obesity care, as they may contribute to the development and maintenance of obesity. The results highlight the importance of both what is assessed and how it is assessed. The results of this study can be used to develop practical tools for facilitating healthcare professionals in conducting a psychosocial and lifestyle assessment.

RESUMO

BACKGROUND: The causes and consequences of childhood obesity are complex and multifaceted. Therefore, an integrated care approach is required to address weight-related issues and improve children's health, societal participation and quality of life. Conducting a psychosocial and lifestyle assessment is an essential part of an integrated care approach. The aim of this study was to explore the experiences, needs and wishes of healthcare professionals with respect to carrying out a psychosocial and lifestyle assessment of childhood obesity. METHODS: Fourteen semi-structured interviews were conducted with Dutch healthcare professionals, who are responsible for coordinating the support and care for children with obesity (coordinating professionals, 'CPs'). The following topics were addressed in our interviews with these professionals: CPs' experiences of both using childhood obesity assessment tools and their content, and CPs' needs and wishes related to content, circumstances and required competences. The interviews comprised open-ended questions and were recorded and transcribed verbatim. The data was analysed using template analyses and complemented with open coding in MAXQDA. RESULTS: Most CPs experienced both developing a trusting relationship with the children and their parents, as well as establishing the right tone when engaging in weight-related conversations as important. CPs indicated that visual materials were helpful in such conversations. All CPs used a supporting assessment tool to conduct the psychosocial and lifestyle assessment but they also indicated that a more optimal tool was desirable. They recognized the need for specific attributes that helped them to carry out these assessments, namely: sufficient knowledge about the complexity of obesity; having an affinity with obesity-related issues; their experience as a CP; using conversational techniques, such as solution-focused counselling and motivational interviewing; peer-to-peer coaching; and finally, maintaining an open-minded, non-stigmatizing stance and harmonizing their attitude with that of the child and their parents. CONCLUSIONS: Alongside the need for a suitable tool for conducting a psychosocial and lifestyle assessment, CPs expressed the need for requisite knowledge, skills and attitudes. Further developing a supporting assessment tool is necessary in order to facilitate CPs and thereby improve the support and care for children with obesity and their families.

RESUMO

BACKGROUND: There is an urgent need to reduce mortality of COVID-19. We examined if corticosteroids and tocilizumab reduce risk for death in patients with severe pneumonia caused by SARS-CoV-2. METHODS: A retrospective cohort study was performed in a single university hospital. All adult patients admitted with confirmed severe COVID-19 pneumonia from 9 March to 9 April 2020 were included. Severe pneumonia was defined as multi-lobar or bilateral pneumonia and a ratio of oxygen saturation by pulse oximetry to the fraction of inspired oxygen (SpFi)<315. All patients received antiviral and antibiotic treatment. From March 26, patients also received immunomodulatory treatment with corticosteroids (methylprednisolone 250 mg/day for 3 days), or tocilizumab or both. In-hospital mortality in the entire cohort and in a 1:1 matched cohort sub-analysis was evaluated. RESULTS: 255 patients were included, 118 received only antiviral and antibiotic treatment while 137, admitted after March 26, also received immunomodulators. In-hospital mortality of patients on immunomodulatory treatment was significantly lower than in those without [47/137(34.3%) vs. 69/118(58.5%), (p < .001)]. The risk of death was 0.44 (CI, 0.26-0.76) in patients receiving corticosteroids alone and 0.292 (CI, 0.18-0.47) in those treated with corticosteroids and tocilizumab. In the sub-analysis with 202 matched patients, the risk of death was 0.356 (CI 0.179-0.707) in patients receiving corticosteroids alone and 0.233 (0.124-0.436) in those treated with the combination. CONCLUSIONS: Combined treatment with corticosteroids and tocilizumab reduced mortality with about 25% in patients with severe COVID-19 pneumonia. Corticosteroids alone also resulted in lower in-hospital mortality rate compared to patients receiving only antiviral and antibiotic treatment. Corticosteroids alone or combined with tocilizumab may be considered in patients with severe COVID-19 pneumonia.

RESUMO

INTRODUCTION: Boceprevir (BOC) was one of the first oral inhibitors of hepatitis C virus (HCV) NS3 protease to be developed. This study assessed the safety and efficacy of BOC+pegylated interferon-α2a/ribavirin (PEG-IFN/RBV) in the retreatment of HIV-HCV co-infected patients with HCV genotype 1. METHODS: This was a phase III prospective trial. HIV-HCV (genotype 1) co-infected patients from 16 hospitals in Spain were included. These patients received 4 weeks of PEG-IFN/RBV (lead-in), followed by response-guided therapy with PEG-IFN/RBV plus BOC (a fixed 44 weeks was indicated in the case of cirrhosis). The primary endpoint was the sustained virological response (SVR) rate at 24 weeks post-treatment. Efficacy and safety were evaluated in all patients who received at least one dose of the study drug. RESULTS: From June 2013 to April 2014, 102 patients were enrolled, 98 of whom received at least one treatment dose. Seventy-three percent were male, 34% were cirrhotic, 23% had IL28b CC, 65% had genotype 1a, and 41% were previous null responders. The overall SVR rate was 67%. Previous null-responders and cirrhotic patients had lower SVR rates (57% and 51%, respectively). Seventy-six patients (78%) completed the therapy scheme; the most common reasons for discontinuation were lack of response at week 12 (12 patients) and adverse events (six patients). CONCLUSIONS: Response-guided therapy with BOC in combination with PEG-IFN/RBV led to an overall SVR rate of 67%, but an SVR rate of only 51% in patients with cirrhosis. The therapy was generally well tolerated. Although the current standards of care do not include BOC+PEG-IFN/RBV, the authors believe that this combination can be beneficial in situations where new HCV direct antiviral agent interferon-free therapies are not available yet.

RESUMO

OBJECTIVES: The aim of the study was to investigate liver fibrosis outcome and the risk factors associated with liver fibrosis progression in hepatitis C virus (HCV)/HIV-coinfected patients. METHODS: We prospectively obtained liver stiffness measurements by transient elastography in a cohort of 154 HCV/HIV-coinfected patients, mostly Caucasian men on suppressive antiretroviral treatment, with the aim of determining the risk for liver stiffness measurement (LSM) increase and to identify the predictive factors for liver fibrosis progression. To evaluate LSM trends over time, a linear mixed regression model with LSM level as the outcome and duration of follow-up in years as the main covariate was fitted. RESULTS: After a median follow-up time of 40 months, the median increase in LSM was 1.05 kPa/year [95% confidence interval (CI) 0.72-1.38 kPa/year]. Fibrosis stage progression was seen in 47% of patients, and 17% progressed to cirrhosis. Aspartate aminotransferase (AST) levels and liver fibrosis stage at baseline were identified as independent predictors of LSM change. Patients with F3 (LSM 9.6-14.5 kPa) or AST levels ≥ 64 IU/L at baseline were at higher risk for accelerated LSM increase (ranging from 1.45 to 2.61 kPa/year), whereas LSM change was very slow among patients with both F0-F1 (LSM ≤ 7.5 kPa) and AST levels ≤ 64 IU/L at baseline (0.34 to 0.58 kPa/year). An intermediate risk for LSM increase (from 0.78 to 1.03 kPa/year) was seen in patients with F2 (LSM 7.6-9.5 kPa) and AST baseline levels ≤ 64 IU/L. CONCLUSIONS: AST levels and liver stiffness at baseline allow stratification of the risk for fibrosis progression and might be clinically useful to guide HCV treatment decisions in HIV-infected patients.

RESUMO

BACKGROUND: Despite the reported decrease in the incidence and mortality rates of central nervous system (CNS) infections after the introduction of highly active antiretroviral therapy (HAART), few studies have focused on the global incidence and the relationship of these diseases with immune reconstitution inflammatory syndrome (IRIS) in the developed world. METHODS: A descriptive cohort study of all consecutive adult HIV-infected patients with CNS opportunistic infections diagnosed between 2000 and 2010 in a tertiary hospital in Spain was carried out. Demographic, clinical, laboratory, and microbiological data were recorded. Patients were followed up until death or loss to follow-up or until 30 July 2011, when the study finished. The significance of differences in the incidence rate between early and late HAART periods was determined using the Mantel-Haenszel test. Survival distribution was estimated using the Kaplan-Meier method. RESULTS: A total of 110 cases of CNS infections were diagnosed. The incidence of CNS opportunistic infections decreased from 9 cases per 1000 HIV-infected patients per year in the early HAART period to 3.8 in the late HAART period (P = 0.04). Overall, the estimated mean survival time was 58.8 months (95% confidence interval 47.1-70.6 months). Of the 110 patients, 18 (16.4%) met the criteria of IRIS, 10 (55.6%) were paradoxical and eight (44.4%) were unmasking. IRIS was not associated with a higher mortality rate. CONCLUSIONS: The annual incidence of CNS infections decreased progressively during the period of study. The mortality rate associated with these diseases remains high despite HAART. The development of IRIS associated with neurological infections had no influence on prognosis.

RESUMO

OBJECTIVES: The aim of the study was to assess the seroprevalence of hepatitis E virus (HEV) infection in an HIV-infected population, as determined by HEV immunoglobulin G (IgG) antibodies (anti-HEV). METHODS: The design of the study was cross-sectional. Serum anti-HEV IgG was determined by enzyme immunoassay in 238 HIV-infected patients consecutively attending our out-patient clinic between April and May 2011. In HEV-seropositive patients, HEV RNA was analysed by nested reverse transcriptase-polymerase chain reaction (RT-PCR). Associations between anti-HEV and liver cirrhosis, route of HIV infection, hepatitis B virus (HBV) and hepatitis C virus (HCV) serological markers, age, sex and alanine aminotransferase (ALT) levels were examined by univariate and multivariate analysis. RESULTS: One hundred and forty patients (59%) had chronic liver disease (99% were HBV- and/or HCV-coinfected). Liver cirrhosis was detected in 44 individuals (19%). Two hundred and twelve patients (89%) were on antiretroviral treatment; the median CD4 T-cell count was 483 cells/µL [interquartile range (IQR) 313-662 cells/µL] and the HIV viral load was <25 HIV-1 RNA copies/mL. Overall, 22 patients (9%) were anti-HEV positive. Liver cirrhosis was the only factor independently associated with the presence of anti-HEV, which was documented in 23% of patients with cirrhosis and 6% of patients without cirrhosis (P=0.002; odds ratio 5.77). HEV RNA was detected in three seropositive patients (14%), two of whom had liver cirrhosis. CONCLUSIONS: Our findings show a high prevalence of anti-HEV in HIV-infected patients, strongly associated with liver cirrhosis. Chronic HEV infection was detected in a significant number of HEV-seropositive patients. Further research is needed to ascertain whether cirrhosis is a predisposing factor for HEV infection and to assess the role of chronic HEV infection in the pathogeneses of cirrhosis in this population.

RESUMO

In a quest for novel cadherin gene family members in the human dbEST database, an interesting EST clone was identified and chosen for subsequent analysis. Using the technique of 5' rapid amplification of cDNA ends, we isolated the complete coding sequence and a large part of the UTRs of a novel gene. The sequence appeared to correspond to the human cadherin-10 gene, whose sequence was only partially known before. The expression pattern of this cadherin was found to be largely brain-specific, with additional expression in both adult and fetal kidney, and with minor expression in prostate and fetal lung. By FISH analysis the genomic location was determined at human chromosome 5p13-14, which is nearby the reported positions of the human cadherin-6, -12, and cadherin-14 (CDH18) genes. Cadherin-10 shows high relationship to the human cadherin-6 gene.

RESUMO

Fractioned irradiation of the oral region may cause xerostomia and an increased infection risk. The aim of this study was to evaluate, in a single blind, cross-over trial, the effectiveness of a test toothpaste containing the lactoperoxidase system, compared to a normal fluoridated toothpaste. Twelve patients with pronounced xerostomia were examined during a 52-day period. The following parameters were observed: plaque and gingivitis index, bleeding on probing, probing pocket depth, attachment level, and quality of subgingival plaque (phase contrast microscopy). The test toothpaste reduced the rate of supragingival plaque formation over a longer period. Furthermore, gingival inflammation was lower in the test group. For the other parameters, time-dependent changes were not significant. This pilot-study demonstrates the efficacy of the lactoperoxidase system administered by a toothpaste, on supragingival plaque control in xerostomic patients.

RESUMO

The alternative oxidase of Moniliella tomentosa mitochondria is stimulated by 5'-AMP. This effect may be masked, depending on the isolation procedure of the mitochondria. The preparation of submitochondrial particles results in the expression of the 5'-AMP effect. Two more methods are now described to reveal the 5'-AMP effect whenever it would be masked: (1) switching on the myokinase activity of the mitochondria to deplete them of endogenous 5'-AMP; (2) using detergents (sodium dodecyl sulphate, sodium deoxycholate) in a controlled detergent:protein ratio, or chloroform. The alternative oxidase of detergent-solubilized mitochondria was somewhat less selective towards nucleotides than were intact mitochondria. The effect of nucleotides on quinol oxidation by mitochondrial preparations and on quinol autoxidation was also studied. Mitochondrial oxidation of succinate by the alternative oxidase and autoxidation of quinols behaved similarly in the presence of certain nucleotides. Both reactions were stimulated. Both reactions were also inhibited by salicylhydroxamic acid. These effects on quinol oxidation disappeared when bovine serum albumin or mitochondrial proteins were present. From the results obtained it is not possible to exclude quinol autoxidation as a final step of the alternative oxidase.
