RESUMO

BACKGROUND: Fabry disease is an inherited metabolic disorder with various symptoms. Neurological manifestations are small fiber neuropathy, cerebral white matter lesions (WML), megadolicho basilar artery, and stroke. The relevance of the D313Y variant in the galactosidase alpha gene is controversially discussed. OBJECTIVES: We aimed at elucidating the implications of this differential diagnosis of multiple sclerosis (MS), focussing on the analysis of WML over time and correlations with other markers. METHODS: We reviewed retrospectively the clinical, laboratory, and magnetic resonance imaging data of 21 carriers of the D313Y variant at a single German outpatient clinic for MS between 2004 and 2021. RESULTS: In our cohort (15 females, 6 males), mean age at diagnosis was 44.1 ± 16.3 years, and mean follow-up duration was 3.1 ± 3.9 years. WML were rated on both, the Fazekas scale and the age-related white matter changes rating scale, and were of variable interindividual extent. Follow-up imaging showed virtually no progress. WML did not correlate with the severity of clinical findings or lysoGb3 levels. Symptomatic carriers of the variant are characterized by an almost complete lack of internal organ manifestations and laboratory findings, usually associated with Fabry disease. CONCLUSION: WML in carriers of the D313Y variant do not seem to be suitable for assessing or predicting the (para-) clinical status. Concerning MS patients, the variant and its clinical signs can be a differential diagnosis, but also a co-factor. Imaging and cerebrospinal fluid findings facilitate the distinction between both entities.

RESUMO

This case report describes a 59-year-old man with myelin oligodendrocyte glycoprotein (MOG)-positive longitudinal extensive transverse myelitis (LETM) after being vaccinated with the COVID-19 vaccine ChAdOx1 nCoV-19. He presented with urinary retention, gait disturbance, hypoesthesia and brisk reflexes in his lower extremities without paresis. Due to the ineffectiveness of high-dose intravenous methylprednisolone, therapeutic plasma exchange was performed, gradually improving the patient's condition. Vaccination as a trigger for an excessive immunological response seems plausible, though unspecific for the ChAdOx1 nCoV-19 vaccine.

RESUMO

BACKGROUND: Allergic diseases pose a health problem worldwide. Pollen are widespread aeroallergens which can cause symptoms like shortness of breath, cough, itchy eyes, or rhinitis. Apart from preventive measures and pharmacological treatment, also non-pharmacological interventions have been suggested to reduce symptoms. The objective of this work was to review studies investigating the effectiveness of non-pharmacologic interventions to reduce allergic symptoms. METHODS: PubMed, EMBASE, and CENTRAL were systematically reviewed in July 2018 and April 2020. Several authors worked on the screening of titles, abstracts, and full texts. One author for each literature search performed the data extraction and the risk of bias assessment. Studies were included if they met the inclusion criteria defined by the PECOs. Studies which investigating the effect of non-pharmacologic interventions on patients with allergic rhinitis were included. RESULTS: Twenty-nine studies investigating eleven types of non-pharmacologic interventions to avoid and reduce allergic symptoms due to pollen exposure were included in this review. Out of all studies, seven studies addressed nasal rinsing and 22 included acupuncture, air filtering, artisanal tears, individual allergen avoidance advice, various nasal applications, self-hypnosis, rhinophototherapy, and wraparound sunglasses. CONCLUSION: Most studies had a high risk of bias and small sample sizes. There were only a few high-quality studies that give hints about the effectiveness of non-pharmacological interventions. For future research, more high-quality studies are required to confirm the effectiveness of simple, safe, and cost-effective interventions.

RESUMO

Giant cell arteritis (GCA) is the most common idiopathic systemic vasculitis in the age group over 50 years. It requires prompt diagnostics and treatment to avoid severe complications, such as visual loss or stroke. The tendency to relapse makes a glucocorticoid (GC) treatment necessary for several years and sometimes lifelong, which increases the risk of GC-induced long-term side effects. Therefore, additive GC-sparing treatment is recommended in the majority of patients. For this purpose, the anti-IL­6 receptor antibody tocilizumab is available as an approved substance for subcutaneous application; alternatively, methotrexate (MTX) can be used (off-label).

RESUMO

OBJECTIVES: Health utility decrement estimates for diabetes and complications are needed for parametrization of simulation models that aim to assess the cost-utility of diabetes prevention and care strategies. This study estimates health utility decrements associated with diabetes and cardiovascular and microvascular complications from a population-based German study. METHODS: Data were obtained from the population based cross-sectional KORA (Cooperative Health Research in the Augsburg Region) health questionnaire 2016 and comprised n = 1072 individuals with type 2 diabetes and n = 7879 individuals without diabetes. Health utility was assessed through the EQ-5D-5L. We used linear regression models with interaction terms between type 2 diabetes and different cardiovascular and microvascular complications while adjusting for demographic and socio-economic factors and other comorbidities. RESULTS: Type 2 diabetes (ß = -0.028, standard error [SE] = 0.014), stroke (ß = -0.070, SE = 0.010), cardiac arrhythmia (ß = -0.031, SE = 0.006), heart failure (ß = -0.073, SE = 0.009), coronary heart disease (ß = -0.028, SE = 0.010), myocardial infarction (ß = -0.020, SE = 0.011, estimates of main effect), and neuropathy (ß = -0.067, SE = 0.020), diabetic foot (ß = -0.042, SE = 0.030), nephropathy (ß = -0.032, SE = 0.025), and blindness (ß = -0.094, SE = 0.056, estimates of interaction terms) were negatively associated with health utility. The interaction term for diabetes x stroke (ß = -0.052, SE = 0.021) showed that the utility decrement for stroke is significantly larger in people with type 2 diabetes than in people without diabetes. CONCLUSIONS: Diabetes, cardiovascular, and microvascular conditions are associated with significant health utility decrements. Utility decrements for some conditions differ between people with and without type 2 diabetes. These results are of high relevance for the parametrization of decision analytic simulation models and applied health economic evaluations in the field of prevention and management of type 2 diabetes in Germany.

RESUMO

BACKGROUND: The role of artisanal and small-scale gold mining (ASGM) as a source of income is rapidly gaining importance in the economically difficult times in Zimbabwe. Small-scale miners are now responsible for over 50% of the Zimbabwean gold production. However, the sector is still characterised by high labour-intensity, low productivity and capital, limited mechanisation and outdated technologies. Since increasing efforts in recent years to improve miners' health while reducing the exposure to mercury have not been effective, a more sustainable approach is needed to identify interventions targeting the health of artisanal and small-scale miners and the mining communities. OBJECTIVE: The main objective of this study was the accurate and extensive empirical identification of the determinants of health in ASGM and of the miners' health needs. In tandem with these needs, topics which generate more effective, sustainable, and feasible future health interventions targeting occupational health should be identified. METHODS: Based on the identification of determinants of health, a health needs assessment (HNA) was used to conduct miners' needs by applying a mixed methods approach and triangulation. This included qualitative and quantitative interviews with individuals, group interviews, focus group discussions, observations and informal conversations. RESULTS: There were 85 structured and 84 semi-structured interviews, a focus group discussion, and observations conducted. Six main themes were identified around which miners' health needs can be aggregated as follows: living conditions, nutrition and hygiene; safe work environment and mining processes; financial support; health care services; formalisation and education. DISCUSSION: The following aspects were considered most important for sustainable interventions: possible health impacts, feasibility, value for miners and their willingness to adapt. Accordingly, interventions aiming at increasing education, knowledge and awareness of miners were identified as most promising in improving occupational health.

RESUMO

BACKGROUND: The role of artisanal and small-scale gold mining (ASGM) as a source of income is rapidly gaining importance in the economically difficult times in Zimbabwe. Besides limited epidemiological data, no data about the self-reported health-related quality of life (HRQoL) of artisanal and small-scale gold miners exist. The aim of the project was to access HRQoL of ASGM workers to improve the data base and compare the data to the urban Zimbabwean population. METHODS: Data from 83 artisanal and small-scale gold miners in Kadoma, Zimbabwe was analysed. The HRQoL was assessed using the EuroQol dimensions (mobility, self-care, usual activities, pain/discomfort, anxiety/depression) accompanied by the cognition add-on questionnaire (EQ-5D-3L+C) and associated visual analogue scale (VAS). We described the EQ-5D dimensions and VAS values and computed health utility (HU) values using the Zimbabwean tariff. The proportions of miners reporting no problem in each EQ-5D dimension were compared with corresponding proportions reporting any problem (moderate or severe), and mean HU and VAS values were analysed across subgroups of the sample. To test differences between subgroups, Fisher's exact test was used and between urban and mining population, Student's t-test was used. RESULTS: The reported health states of miners were homogenous, with a large amount (42%) reporting 'full health'. Mean (SD) VAS and HU values were 81.0 (17.5) and 0.896 (0.13), respectively. Subgroup analysis showed that miners with a lower education reported significantly more problems in the dimension of daily activities and miners with mercury contact had more problems in the dimensions of pain/discomfort and cognition. Comparison between mining and urban population showed that in the oldest age group, self-rated VAS values of miners were significantly higher than of their urban counterparts. CONCLUSIONS: There were no significant differences in the HRQoL of mining and urban populations. However, the reason might be adverse health effects faced by the urban population that do not apply to rural mining areas. A higher education level of miners can improve the HRQoL, which is especially impaired by problems in the cognition dimension.

RESUMO

White matter lesions (WML) in younger patients might be due to a variety of neurological disorders. Fabry disease (FD), an x-linked inherited lysosomal storage disorder, happens to be misdiagnosed as multiple sclerosis (MS). In two middle-aged female patients, presenting bilateral WML, diagnosis of MS turned out to be doubtful. Human genetic analysis presented the Fabry mutation D313Y, in which clinical impact is still unclear. Disease manifestations outside the central nervous system were not detected. Our findings support the suspicion that Fabry mutation D313Y may be involved in neural damage resulting in WML.

RESUMO

A new redox polymer/bilirubin oxidase (BOD)-based gas diffusion electrode was designed to be implemented as the non-current and non-stability limiting biocathode in a glucose/O2 biofuel cell that acts as a self-powered glucose biosensor. For the proof-of-concept, a bioanode comprising the Os-complex modified redox polymer P(VI-co-AA)-[Os(bpy)2Cl]Cl and FAD-dependent glucose dehydrogenase to oxidize the analyte was used. In order to develop an optimal O2-reducing biocathode for the biofuel cell Mv-BOD as well as Bp-BOD and Mo-BOD have been tested in gas diffusion electrodes in direct electron transfer as well as in mediated electron transfer immobilized in the Os-complex modified redox polymer P(VI-co-AA)-[Os(diCl-bpy)2]Cl2. The resulting biofuel cell exhibits a glucose-dependent current and power output in the concentration region between 1 and 10 mM. To create a more realistic test environment, the performance and long-term stability of the biofuel cell-based self-powered glucose biosensor has been investigated in a flow-through cell design.

RESUMO

BACKGROUND AND PURPOSE: Optimal treatment of intracranial stenoses in varicella zoster virus (VZV)-associated vasculitis is unknown. This study aims to evaluate the merits and potential pitfalls of a specific therapeutic strategy, initially proposed by Don Gilden in 2015. METHODS: We describe three patients with intracranial stenoses caused by VZV vasculitis successfully treated by a long-term combination of valacyclovir and prednisolone. RESULTS: All three patients were young men suffering from stroke. Only one reported a first contact to VZV in adulthood. All three presented stenoses in the intracranial part of the internal carotid artery or the proximal segments of the middle cerebral artery as well as an elevated cell count and positive VZV antibody index in cerebrospinal fluid. They received a combination therapy regimen with prednisone and valacyclovir about a minimum of one year. Intracranial stenoses improved markedly in one and almost resolved completely in the other two patients. Side effects of corticosteroid treatment occurred in two patients. CONCLUSIONS: Long-term combination treatment with prednisone and valacyclovir proved to be effective in three young men suffering from intracranial stenosis due to VZV vasculitis.

RESUMO

The development of electrodes for efficient CO2 reduction while forming valuable compounds is critical. The use of enzymes as catalysts provides the advantage of high catalytic activity in combination with highly selective transformations. We describe the electrical wiring of a carbon monoxide dehydrogenase II from Carboxydothermus hydrogenoformans (ChCODH II) using a cobaltocene-based low-potential redox polymer for the selective reduction of CO2 to CO over gas diffusion electrodes. High catalytic current densities of up to -5.5 mA cm-2 are achieved, exceeding the performance of previously reported bioelectrodes for CO2 reduction based on either carbon monoxide dehydrogenases or formate dehydrogenases. The proposed bioelectrode reveals considerable stability with a half-life of more than 20 h of continuous operation. Product quantification using gas chromatography confirmed the selective transformation of CO2 into CO without any parasitic co-reactions at the applied potentials.

RESUMO

Artisanal and small-scale gold mining (ASGM) is often associated with no or compromised attention to health and safety. Although headlines of fatal accidents in Zimbabwe characterise ASGM, little attention is paid to prevention strategies. This study, therefore, explores health and safety risk mitigation in ASGM in Zimbabwe to inform prevention strategies. A qualitative design was used with focus group discussions and in-depth interviews. Data were analysed using thematic analysis, coding, and descriptive statistics. Reported factors contributing to compromised health and safety included immediate causes, workplace factors, ASM related factors, and contextual factors, with interconnectedness between the causal factors. In addition, factors related to ASGM were significant. For risk mitigation, formalisation, organisation of risk reduction, behaviour change, and enforcement of prevention strategies is proposed. A multi-causal analysis is recommended for risk assessment and accident investigation. A multi-stakeholder approach could be considered for risk mitigation including community and public health interventions. However, risk mitigation has been characterised by gaps and weaknesses such as lacking ASM policy, lack of capital, poor enforcement, negative perceptions, and non-compliance. Therefore, we recommend addressing the threats associated with health and safety mitigation to ensure health and safety protection in ASGM.

RESUMO

BACKGROUND: In 2012, the so-called ambulatory medical specialist care (ASV) was implemented in accordance with para. 116b of Book V of the German Social Code (SGB V), enabling physicians in outpatient practices and hospitals to treat patients with rare diseases or complex courses of disease in a uniform framework. The implementation, however, is slow. The Joint Federal Committee (G-BA) has therefore commissioned an evaluation of the ASV with the aim to examine the reasons for this and to provide recommendations for further development. METHODS: The health services research study "GOAL-ASV" (Innovation Fund, 01VSF19002) included a multi-perspective design with primary data collection as well as secondary data analyses. Data from the ASV service center and the central association of statutory health insurances and the notification forms of the extended state committees were analyzed. Data from the Robert Koch-Institute, the Federal Joint Committee, the National Association of Statutory Health Insurance Funds and a literature database analysis were used in order to estimate the proportion of insured persons qualifying for ASV. Care was examined by analyzing pseudonymized routine data from the statutory health insurances using selected indicators. Participating and not participating physicians were asked to complete an online survey. RESULTS: Since the start of ASV, 615,531 insured persons have been treated in this form of care. At the time of analysis, 509 teams were operating, with 26,540 physicians treating 102,898 patients by the end of March 2021 in all indications. This comprises less than 9.8 %. of all approx. 1.05 million eligible patients. Especially in the case of rare diseases, a low willingness of participation can be seen. In addition, there was a relevant proportion of multiple uses of physicians within and outside ASV at 31 percent as well as indications of passive participation of doctors. We found significant regional differences in type and scope of the notification procedure as well as the implementation of teams with 13.4 teams per 1 million inhabitants in Schleswig-Holstein and no team in Mecklenburg-Vorpommern. Patient benefits (84 %), interdisciplinary (82 %) and cross-sectoral cooperation (75 %) were cited as motivations for participation. The main barriers reported by the respondents were the complex and laborious notification procedure (60 %), the administrative and documentation effort during participation (50 %), insufficient billing figures (49 %), and a small proportion of patients (32 %) with a consecutively unfavorable assessment of the cost to income ratio due to the current reimbursement system. DISCUSSION: Nearly ten years after its introduction, the ASV has not become established nationwide. The reasons for this probably are the complex notification procedure and the reimburesement system for rare diseases. In the case of rare diseases, the risk of underuse is becoming apparent. CONCLUSION: Strategies to further develop the ASV should, in particular, simplify the notification procedure and reduce the obstacles during participation. The remuneration system should take more account of the specific care required.

RESUMO

AIMS: Self-management behavior (SMB) is an important aspect in the management of diabetes. This study aimed to identify sociodemographic and disease-related factors associated with good SMB in people with type 2 diabetes (T2D). METHODS: We used data from 479 people with T2D aged 65 or older from the population-based KORA (Cooperative Health Research in the Area of Augsburg) Health Survey 2016 in Southern Germany. We estimated Poisson and logistic regression models testing the cross-sectional relationship between individual or disease-related characteristics and an established SMB sum index comprising six SMB dimensions stratified according to insulin treatment status. RESULTS: Mean age in the sample was 75 and mean diabetes duration was 13 years. The overall level of SMB was low. Higher SMB index scores were associated with higher age, treatment with insulin, participation in a diabetes education program, and, for people with insulin treatment, with a BMI below 30 kg/m2. Single item analyses generally supported these findings. CONCLUSIONS: SMB in people with T2D needs to be improved with efficient interventions. Targeting obese individuals and those at an early stage of the disease with low-barrier, regular education or self-management programs may be a preferred strategy.

RESUMO

AIMS: To identify socioeconomic, behavioral and clinical factors that are associated with prediabetes according to different prediabetes definition criteria. METHODS: Analyses use pooled data of the population-based Cooperative Health Research in the Region of Augsburg (KORA) studies (n = 5312 observations aged ≥ 38 years without diabetes). Prediabetes was defined through either impaired fasting glucose (IFG), impaired glucose tolerance (IGT) or elevated HbA1c according to thresholds of the American Diabetes Association. Explanatory variables were regressed on prediabetes using generalized estimating equations. RESULTS: Mean age was 58.4 years; 50% had prediabetes (33% had IFG, 16% IGT, and 26% elevated HbA1c, 10% fulfilled all three criteria). Age, obesity, hypertension, low education, unemployment, statutory health insurance, urban residence and physical inactivity were associated with prediabetes. Male sex was a stronger risk factor for IFG (OR = 2.5; 95%-CI: 2.2-2.9) than for IGT or elevated HbA1c, and being unemployed was a stronger risk factor for IGT (OR = 3.2 95%-CI: 2.6-4.0) than for IFG or elevated HbA1c. CONCLUSIONS: The overlap of people with IFG, IGT and elevated HbA1c is small, and some factors are associated with only one criterion. Knowledge on sociodemographic and socioeconomic risk factors can be used to effectively target interventions to people at high risk for type 2 diabetes.

RESUMO

During extinction learning (EL), an individual learns that a previously learned behavior no longer fulfills its original purpose, or is no longer relevant. Recent studies have contradicted earlier theories that EL comprises forgetting, or the inhibition of the previously learned behavior, and indicate that EL comprises new associative learning. This suggests that the hippocampus is involved in this process. Empirical evidence is lacking however. Here, we used fluorescence in situ hybridization of somatic immediate early gene (IEG) expression to scrutinize if the hippocampus processes EL. Rodents engaged in context-dependent EL and were also tested for renewal of (the original behavioral response to) a spatial appetitive task in a T-maze. Whereas distal and proximal CA1 subfields processed both EL and renewal, effects in the proximal CA1 were more robust consistent with a role of this subfield in processing context. The lower blade of the dentate gyrus (DG) and the proximal CA3 subfields were particularly involved in renewal. Responses in the distal and proximal CA3 subfields suggest that this hippocampal subregion may also contribute to the evaluation of the reward outcome. Taken together, our findings provide novel and direct evidence for the involvement of distinct hippocampal subfields in context-dependent EL and renewal.

RESUMO

AIM: The aim of this analysis was to assess changes in lipid parameters, specifically in triglyceride (TG) levels, in a population at ultra-high risk (UHR) for psychosis treated with ω-3 polyunsaturated fatty acids (PUFAs) versus placebo. METHODS: Data were derived from a randomized, double-blind, placebo-controlled trial conducted at an early psychosis unit. Eighty-one individuals, aged 13-25 years, at UHR for psychosis participated in a 12-week intervention trial of 1.2 g/day of ω-3 PUFAs (n = 41) versus placebo (n = 40). Lipid and C-reactive protein levels were collected at baseline and after 12 weeks. RESULTS: Between-group comparisons showed no significant difference in TG levels after the intervention. However, in individuals with baseline TG levels above 150 mg dL-1 there was a significant mean TG reduction of 67.29 (SD 42.54; P = 0.006) in the ω-3 group (n = 7). CONCLUSION: In this sample of UHR individuals, a 12-week intervention with ω-3 PUFAs was effective in reducing previously elevated TG levels. This might introduce the possibility of altering the lipid profile and thus the risk of cardiovascular morbidity of UHR individuals.

RESUMO

OBJECTIVES: The etiology and genetic susceptibility of primary central nervous system vasculitis (PCNSV) are still unclear. PATIENTS AND METHODS: We analyzed the DNA of 25 Caucasian patients with PCNSV for human leucocyte antigen genes HLA-A, HLA-B, HLA-DRB1, and HLA-DQB1, respectively. HLA-frequencies of the 25 patients with PCNSV were compared with HLA-frequencies of matched Caucasian controls. RESULTS: No statistically significant associations were found for HLA-B, HLA-DR1 and HLA-DQB1 variant. In the PCNSV group, only the HLA-A*69 variant was found more often than expected statistically. CONCLUSION: The results of this study indicate a potential association of HLA marker with PCNSV in Caucasian patients. Further studies are needed to elucidate the role of genes within the human major histocompatibility complex in the pathogenesis of this angiopathy.

RESUMO

A need for a brief, easy to complete self-report questionnaire to detect people at ultra-high risk for psychosis (UHR) in busy clinical settings has been recognised. Our aim was to explore whether the Community Assessment of Psychic Experiences - Positive 15-items Scale (CAPE-P15) could be used as a screening tool to identify people at UHR in a clinical setting. Our objectives were to confirm the CAPE-P15 factorial structure as well as its reliability and determine cut-off values for the detection of such individuals using the Comprehensive Assessment of At-Risk Mental States (CAARMS), a commonly used clinical interview for the detection of UHR. 165 participants aged between 13 and 18 referred to the General Hospital of Vienna were included in the analysis. 50.9% of the sample were "CAARMS-positive" and 49.1% "CAARMS-negative". The Youden method determined CAPE-P15 cut-off values for UHR detection of 1.47 for both frequency of and distress associated with psychotic experiences. The cut-off value of 1.47 for frequency showed sensitivity of 77%, specificity of 58%, a positive predictive value of 66% and a negative predictive value of 71%; whilst for distress it showed sensitivity of 73%, specificity of 63%, a positive predictive value of 69% and a negative predictive value of 66%. Good reliability and the previously suggested three-correlated factor model as well as an alternative bi-factor model of the CAPE-P15 were confirmed. The CAPE-P15 seems to be a promising screening tool for identifying people who might be at UHR in busy clinical settings.
