Environmental lead exposure has been a much-discussed risk factor for the development of ADHD for decades. However, due to methodological shortcomings, the existing research on this topic is highly inconsistent. We will attempt to clarify this question by performing a meta-analysis based on a systematic literature search until February 2024 including different databases such as Pubmed and Google Scholar.

Methods: We chose a meta-analytical approach and searched for relevant studies in different databases (Pubmed, PsycInfo, Google scholar). We identified 24 studies with 18 859 participants (mean age = 18.
Background: Aluminum is increasingly used in various industrial processes due to its beneficial properties. Occupational exposure to aluminum, however, has been linked to several adverse health effects. The impact of occupational aluminum exposure on worker's cognitive performance and its contribution in developing neurodegenerative diseases is highly discussed with competing results.

Occupational manganese exposure is associated with serious health concerns, ultimately leading to an illness called manganism. Competing meta-analytic results were published over a decade ago, ranging from undetectable to serious effects on cognitive performance among working adults. Novel studies and findings about the relationship between occupational manganese and cognitive functions have been proposed since.

Since affected persons seldom seek professional help, online interventions can improve accessibility. Thus, this study aimed to investigate the effectiveness of psychological online interventions on PGGD.

Despite the beneficial properties, its impact on the neurobehavioural performance of exposed subjects remains controversial. This meta-analysis aimed to provide the first summarising effects regarding the association between shift work exposure and different cognitive functions.
View Article and Find Full Text PDFBackground: Recent research links problematic smartphone use (PSU) and mental health problems. The purpose of this meta-analysis was to evaluate the relationship between PSU and symptoms of anxiety and/or depression.
Methods: We searched for research literature published recently in PubMed and Google Scholar via a systematic literature search.
Objective: Problematic Internet and smartphone use is associated with serious mental health problems. We thus investigated the effectiveness of psychological interventions on problematic Internet and smartphone use.
Methods: We conducted a systematic review and meta-analysis and searched in PubMed, PsyArticles, PsycInfo, Medline and Google Scholar for peer-reviewed experimental and quasi-experimental research published between 2008 and 2021.
Our study explores the relationships between traffic-psychological driving-related personality traits, fluid intelligence, and cognitive abilities for drivers whose driver license has been revoked due to intoxicated driving (alcohol and/or drugs). We were able to show that high significant impacts on cognitive functions derive from the participants' age and fluid intelligence. In addition, driving-related personality traits like emotional instability, sense of responsibility and self-control contributed significantly to some of the cognitive abilities that are important for the fitness to drive.

The aim of this study was to estimate the long-term effects of parental divorce on their offspring's mental health as well as substance-based addiction. We performed a systematic literature search on PubMed, Medline, PsyINFO, PsyARTICLES and PsycNET for the time period from 1990 until March 2018 in English language. In total 54 studies were included in the meta-analysis resulting in 117 effect sizes as well as a total sample of 506,299 participants.

This metaanalysis aimed to investigate associations between neurocognitive performance and lead exposure in adults and further assess potential effect thresholds.
Material And Methods: Articles indexed in Medline published until January 2017 reporting associations between lead exposure, blood lead, cognitive abilities and sensomotoric performance were included.
It is unclear whether electromagnetic fields emitted by mobile phone base stations affect well-being in adults. The existing studies on this topic are highly inconsistent. In the current paper we attempt to clarify this question by carrying out a meta-analysis which is based on the results of 17 studies.

However, the results have been ambiguous. The current meta-analysis aims to clarify whether RF-EMF have an influence on well-being in self-reported sensitive persons, as well as in non-sensitive people.

Methods: A prospective, randomized, four-tailed controlled pilot trial was performed to compare the effect of skin protection and skin care alone or in combination with cleansing against a control group (only cleansing). Two branches were selected for the investigation: the building industry and the timber industry.
Purpose: To investigate the role of inflammatory and angiogenic factors in the pathogenesis of diabetic retinopathy, we determined, in diabetic patients and controls, vitreous and serum concentrations of interferon-induced protein (IP)-10, monocyte chemoattractant protein (MCP)-1, macrophage inflammatory protein (MIP)-1alpha, MIP-1beta, regulated upon activation, normal T-expressed and secreted (RANTES), and vascular endothelial growth factor (VEGF).
Methods: We recruited 36 probands with type 2 diabetes mellitus (15 noninsulin-dependent and 21 insulin-dependent) and 69 normal controls. Using Cytometric Bead Array Technology, we measured vitreous and serum concentrations of IP-10, MCP-1, MIP-1alpha, MIP-1beta, RANTES, and VEGF.

Objectives: The aim of this paper was to analyze the impact of economic growth measured by real gross domestic product (GDP) on the incidence of occupational injuries in Austria.
Methods: The relationship between GDP and the occupational injury rate of the wage-earning population between 1955 and 2004 was analyzed using an error correction model. The sample size increased from 1.
Purpose: This study was carried out to compare cytometric bead array (CBA) technology with conventional enzyme linked immunosorbent assay (ELISA) for the measurement of both vitreous and serum concentrations of interleukin-8 (IL-8), vascular endothelial growth factor (VEGF), and angiogenin (ANG) in diabetic and non-diabetic patients.
Methods: Measurement of vitreous and serum concentrations of IL-8, VEGF, and ANG using both ELISA and CBA was performed in 26 probands (13 diabetics and 13 non-diabetic control subjects).
Results: Vitreous and serum concentrations of IL-8, VEGF, and ANG determined by CBA showed a strong correlation with those measured by ELISA.
A simple, rapid and reproducible procedure for the identification and determination of extracellular saccharase from culture medium of watermelon cell suspension cultures is described. The culture medium (without cells) was used for the identification and determination of extracellular enzyme activity. Intracellular activity was estimated from the cell suspension.

Aim: To investigate whether a decrease in physical working capacity occurs during the first year of unemployment and if this is accompanied by a deterioration in mental health.
Methods: In a longitudinal study, 71 unemployed individuals were investigated for 1, 6 months and 1 year after becoming unemployed. An additional 102 individuals who have been unemployed for more than 1 year were included in the cross-sectional part of the study.
Watermelon cells after permeabilization in Tween 80 were immobilized by glutaraldehyde without any carrier. Cells immobilized by cross-linking demonstrated significantly lower aminopeptidase activities than untreated cells. Pectate and alginate hydrogels were used successfully for immobilization of watermelon cells which retained activities of some aminopeptidases.
