    Abstract Background: Systemic therapy (ST) is a psychotherapeutic intervention in complex human systems (both psychological and interpersonal). Cognitive behavioural therapy (CBT) is an established treatment for children and adolescents with mental disorders. As methodologically rigorous systematic reviews on ST in this population are lacking, we conducted a systematic review and meta-analysis to compare the benefit and harm of ST (and ST as an add-on to CBT) with CBT in children and adolescents with mental disorders.
    Methods: We searched MEDLINE, Embase, PsycINFO and other sources for randomised controlled trials in 14 mental disorder classes for the above comparisons in respect of effects on patient-relevant outcomes (search date: 7/2022). Where possible, meta-analyses were performed and results were graded into 3 different evidence categories: "proof", "indication", or "hint" (or none of these categories). PRISMA standards were followed.
    Results: Fifteen studies in 5 mental disorder classes with usable data were identified. 2079 patients (mean age: 10 to 19 years) were analysed. 12/15 studies and 29/30 outcomes showed a high risk of bias. In 2 classes, statistically significant and clinically relevant effects in favour of ST were found, supporting the conclusion of a hint of greater benefit of ST for mental and behavioural disorders due to psychoactive substance use and of ST as an add-on to CBT for obsessive-compulsive disorders. In 2 other classes (eating disorders; hyperkinetic disorders), there was no evidence of greater benefit or harm of ST. For affective disorders, a statistically significant effect to the disadvantage of ST was found for 1 outcome, supporting the conclusion of a hint of lesser benefit of ST.
    Conclusions: Our results show a hint of greater benefit of ST (or ST as an add-on to CBT) compared with CBT for 2 mental disorder classes in children and adolescents (mental and behavioural disorders due to psychoactive substance use, obsessive compulsive disorders). Given the importance of CBT as a control intervention, ST can therefore be considered a beneficial treatment option for children and adolescents with certain mental disorders. Limitations include an overall high risk of bias of studies and outcomes and a lack of data for several disorders.

    Abstract Background: Negative pressure wound therapy (NPWT) is a widely used method of wound treatment. We performed a systematic review of randomised controlled trials (RCTs) comparing the patient-relevant benefits and harms of NPWT with standard wound therapy (SWT) in patients with wounds healing by secondary intention.
    Methods: We searched for RCTs in MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, and study registries (last search: July 2018) and screened reference lists of relevant systematic reviews and health technology assessments. Manufacturers and investigators were asked to provide unpublished data. Eligible studies investigated at least one patient-relevant outcome (e.g. wound closure). We assessed publication bias and, if feasible, performed meta-analyses, grading the results into different categories (hint, indication or proof of a greater benefit or harm).
    Results: We identified 48 eligible studies of generally low quality with evaluable data for 4315 patients and 30 eligible studies with missing data for at least 1386 patients. Due to potential publication bias (proportion of inaccessible data, 24%), we downgraded our conclusions. A meta-analysis of all wound healing data showed a significant effect in favour of NPWT (OR 1.56, 95% CI 1.15 to 2.13, p = 0.008). As further analyses of different definitions of wound closure did not contradict that analysis, we inferred an indication of a greater benefit of NPWT. A meta-analysis of hospital stay (in days) showed a significant difference in favour of NPWT (MD - 4.78, 95% CI - 7.79 to - 1.76, p = 0.005). As further analyses of different definitions of hospital stay/readmission did not contradict that analysis, we inferred an indication of a greater benefit of NPWT. There was neither proof (nor indication nor hint) of greater benefit or harm of NPWT for other patient-relevant outcomes such as mortality and adverse events.
    Conclusions: In summary, low-quality data indicate a greater benefit of NPWT versus SWT for wound closure in patients with wounds healing by secondary intention. The length of hospital stay is also shortened. The data show no advantages or disadvantages of NPWT for other patient-relevant outcomes. Publication bias is an important problem in studies on NPWT, underlining that all clinical studies need to be fully reported.

    Abstract In this report, we confirm our previous findings of increased concentrations of soluble amyloid-β protein precursor (sAβPP) in cerebrospinal fluid (CSF) of patients with Alzheimer's disease (AD) and mild cognitive impairment (MCI) in a large cohort of patients (n = 314), not overlapping with those of our previous study, and we extend our observations by including a control group of participants with normal cognition. In addition, we investigate the effects of age, the APOEε4 genotype, and the blood-CSF barrier function on the concentrations of sAβPPα and sAβPPβ. The study participants were categorized according to clinical-neuropsychological criteria, supported by CSF neurochemical dementia diagnostics (NDD) analyses. sAβPPα concentrations in the AD group (132.0 ± 44.8) were significantly higher than in the control group (105.3 ± 37.3, p < 0.0005) but did not differ from the MCI-AD group (138.5 ± 39.5, p = 0.91). The MCI-AD group differed significantly from the MCI-O (97.3 ± 34.3, p < 0.05) group. There was no difference between the control and the MCI-O groups (p = 0.94). Similarly, sAβPPβ concentrations in the AD group (160.2 ± 54.3) were significantly higher than in the control group (129.9 ± 44.6, p < 0.005) but did not differ from the MCI-AD group (184.0 ± 56.4, p = 0.20). The MCI-AD group differed significantly from the MCI-O (127.8 ± 46.2, p < 0.05) group. There was no difference between the control and the MCI-O groups (p > 0.99). We observed highly significant correlation of the two sAβPP forms. Age and the CSF-serum albumin ratio were significant albeit weak predictors of the sAβPPα and sAβPPβ concentrations, while carrying the APOEε4 allele did not influenced the levels of the sAβPP forms. Taken together, the results strongly suggest that CSF sAβPP concentrations may be considered as an extension of already available NDD tools.

    Abstract Abstract Reporting bias represents a major problem in the assessment of health care interventions. Several prominent cases have been described in the literature, for example, in the reporting of trials of antidepressants, Class I anti-arrhythmic drugs, and selective COX-2 inhibitors. The aim of this narrative review is to gain an overview of reporting bias in the medical literature, focussing on publication bias and selective outcome reporting. We explore whether these types of bias have been shown in areas beyond the well-known cases noted above, in order to gain an impression of how widespread the problem is. For this purpose, we screened relevant articles on reporting bias that had previously been obtained by the German Institute for Quality and Efficiency in Health Care in the context of its health technology assessment reports and other research work, together with the reference lists of these articles. We identified reporting bias in 40 indications comprising around 50 different pharmacological, surgical (e.g. vacuum-assisted closure therapy), diagnostic (e.g. ultrasound), and preventive (e.g. cancer vaccines) interventions. Regarding pharmacological interventions, cases of reporting bias were, for example, identified in the treatment of the following conditions: depression, bipolar disorder, schizophrenia, anxiety disorder, attention-deficit hyperactivity disorder, Alzheimer's disease, pain, migraine, cardiovascular disease, gastric ulcers, irritable bowel syndrome, urinary incontinence, atopic dermatitis, diabetes mellitus type 2, hypercholesterolaemia, thyroid disorders, menopausal symptoms, various types of cancer (e.g. ovarian cancer and melanoma), various types of infections (e.g. HIV, influenza and Hepatitis B), and acute trauma. Many cases involved the withholding of study data by manufacturers and regulatory agencies or the active attempt by manufacturers to suppress publication. The ascertained effects of reporting bias included the overestimation of efficacy and the underestimation of safety ...

    Abstract PPARs belong to a receptor family of ligand-activated transcription factors involved in the regulation of inflammation. A crucial role both for PPARgamma and for PPARalpha for the regulation of autoimmunity has been clearly demonstrated, as receptor agonists had beneficial effects on several CD4(+) T cell mediated autoimmune diseases including experimental autoimmune encephalomyelitis (EAE), the animal model of multiple sclerosis. We investigated the association of two common single nucleotide polymorphisms in the PPARA (Leu162Val) and the PPARG (Pro12Ala) genes in 116 patients with clinically definite multiple sclerosis (MS) and 211 age-matched healthy controls. The Ala allele of the PPARG Pro12Ala polymorphism was strongly associated with delayed disease onset (44.1+/-5.3 years vs 34.5+/-4.2 years; p=0.006). No significant differences were found in genotype distributions and allele frequencies of the PPARA Leu162Val and the PPARG Pro12Ala polymorphisms between MS patients and healthy controls, respectively. Our population-based study demonstrates that the Pro12Ala polymorphism resulting in an amino acid exchange in the N-terminal sequence of PPARgamma may influence the onset of MS.

    Abstract Objective: Several predictors of Alzheimer's disease (AD) have been identified. However, the relevance and independent contribution of risk factors and of possible early signs such as mild cognitive impairment and subjective memory impairment on the development of AD has not been investigated prospectively in a cohort of non-demented elderly including first-degree relatives of AD subjects.
    Method: The development of AD was investigated in 757 non-demented elderly. Initial diagnoses were made from personal interviews. Information on 633 subjects after 4.7 +/- 1.2 years (mean +/- SD) was obtained either from personal or family history interviews. Using forward logistic regression analysis, predictors were identified by comparing their presence in 38 subjects who developed AD and 577 subjects who remained non-demented.
    Results: The most important predictors of later Alzheimer's disease were increased age (Odds ratio OR = 1.086/additional year, p < 0.001), initial subjective memory complaints (OR = 2.68, p = 0.019), initial mild cognitive impairment (OR = 2.51, p = 0.032) and female gender (OR = 2.84, p = 0.069). Exploratory analysis revealed that previous depression after the age of 60 years (OR = 2.37, p = 0.033) and the presence of the apolipoprotein E4 allele (OR = 2.49, p = 0.043) individually predicted new AD during follow-up. A positive family history of AD (i. e. being a first degree relative of a subject suffering from AD) did not significantly influence the development of AD (p > 0.2).
    Conclusions: Increased age, the presence of mild cognitive impairment, subjective memory impairment and gender are the most relevant independent predictors of later Alzheimer's disease that may be used in combination for clinical prediction of AD.

    Abstract The disturbances of the cholesterol synthesis and metabolism described in Alzheimer's disease (AD) may be both a consequence of the neurodegenerative process and a contributor to the pathogenesis. These putative relationships and their underlying mechanisms are not well understood. The aim of this study was to evaluate the relationship between the cerebral and extracerebral cholesterol synthesis and metabolism, and the AD pathology as reflected by CSF markers in humans. We evaluated the relationships between the plasma and the cerebrospinal fluid (CSF) concentrations of cholesterol, the cholesterol precursors lanosterol, lathosterol and desmosterol, and the cholesterol elimination products 24S-hydroxycholesterol and 27-hydroxycholesterol, and the CSF markers for AD pathology Aβ1–42 and p-tau181 in 86 subjects with normal cognition and in 107 AD patients. CSF desmosterol, cholesterol and 24S-hydroxycholesterol in the AD group, and CSF 24S-hydroxycholesterol in the control group correlated with the p-tau181 levels. Neither CSF nor plasma concentrations of the included compounds correlated with the CSF Aβ1–42 levels. In multivariate regression tests including age, gender, albumin ratio, number of the APOEɛ4 alleles, and diagnosis, p-tau181 levels independently predicted the CSF desmosterol, cholesterol and 24S-hydroxycholesterol concentrations. The associations remained significant for CSF cholesterol and 24S-hydroxycholesterol when analyses were separately performed in the AD group. The results suggest that alterations of CNS cholesterol de novo genesis and metabolism are related to neurodegeneration and in particular to the cerebral accumulation of phosphorylated tau.

    Abstract Cerebral and extracerebral cholesterol metabolism are altered in Alzheimer's disease (AD) as indicated by reduced plasma levels of the cholesterol elimination products 24S-hydroxycholesterol, which is of cerebral origin, and of 27-hydroxycholesterol, which is formed extracerebrally. However, it has to be evaluated, if changes of cholesterol metabolism in the whole body or in the CNS are exclusively due to the altered elimination of cholesterol or are also due to altered de novo synthesis in AD. We investigated CSF and plasma levels of cholesterol and of its precursors lanosterol, lathosterol and desmosterol in AD patients and non-demented controls. We found CSF levels of cholesterol (p=0.011), absolute levels of all investigated cholesterol precursors (each p<0.001) and ratios of cholesterol precursors/cholesterol (each <0.01) to be lower in AD patients as compared to controls. In plasma, the absolute levels of lanosterol (p=0.026) and lathosterol (p<0.001) and the ratio of lathosterol/cholesterol (p=0.002) but none of the other investigated parameters were reduced in AD patients (p>0.1). Furthermore, ratios of desmosterol/lathosterol in CSF (p=0.023) and plasma (p=0.009) were higher in AD patients as compared to controls. Our data support the hypothesis that cholesterol metabolism is altered in AD and further suggest that especially cholesterol de novo synthesis within the CNS of AD patients might be reduced. These findings raise doubt on a beneficial effect of cholesterol lowering treatment in manifest AD.
