© 2020 Elsevier GmbH Background: The existing data demonstrate that alteration of trace element and mineral status in children with neurodevelopmental disorders including ASD and ADHD. However, comparative analysis of the specific patterns of trace element and mineral metabolism in children with ASD and ADHD was not performed. Therefore, the primary objective of the present study was to assess hair trace element and mineral levels in boys with ADHD, ASD, as well as ADHD with ASD. Methods: Boys with ADHD (n = 52), ASD (n = 53), both ADHD and ASD (n = 52), as well as neurotypical controls (n = 52) were examined. Hair analysis was performed using inductively-coupled plasma mass-spectrometry. Results: The obtained data demonstrate that hair Co, Mg, Mn, and V levels were significantly reduced in children with ADHD and ASD, and especially in boys with ADHD + ASD. Hair Zn was found to be reduced by 20% (p = 0.009) only in children with ADHD + ASD as compared to healthy controls. Factor analysis demonstrated that ASD was associated with significant alteration of hair Co, Fe, Mg, Mn, and V levels, whereas impaired hair Mg, Mn, and Zn content was also significantly associated with ADHD. In regression models hair Zn and Mg were negatively associated with severity of neurodevelopmental disorders. The revealed similarity of trace element and mineral disturbances in ASD and ADHD may be indicative of certain similar pathogenetic features. Conclusion: The obtained data support the hypothesis that trace elements and minerals, namely Mg, Mn, and Zn, may play a significant role in development of both ADHD and ASD. Improvement of Mg, Mn, and Zn status in children with ASD and ADHD may be considered as a nutritional strategy for improvement of neurodevelopmental disturbances, although clinical trials and experimental studies are highly required to support this hypothesis.

© 2018 Radboud University Medical Center Attention-deficit/hyperactivity disorder (ADHD) is highly heritable and the most common neurodevelopmental disorder in childhood. In recent decades, it has been appreciated that in a substantial number of cases the disorder does not remit in puberty, but persists into adulthood. Both in childhood and adulthood, ADHD is characterised by substantial comorbidity including substance use, depression, anxiety, and accidents. However, course and symptoms of the disorder and the comorbidities may fluctuate and change over time, and even age of onset in childhood has recently been questioned. Available evidence to date is poor and largely inconsistent with regard to the predictors of persistence versus remittance. Likewise, the development of comorbid disorders cannot be foreseen early on, hampering preventive measures. These facts call for a lifespan perspective on ADHD from childhood to old age. In this selective review, we summarise current knowledge of the long-term course of ADHD, with an emphasis on clinical symptom and cognitive trajectories, treatment effects over the lifespan, and the development of comorbidities. Also, we summarise current knowledge and important unresolved issues on biological factors underlying different ADHD trajectories. We conclude that a severe lack of knowledge on lifespan aspects in ADHD still exists for nearly every aspect reviewed. We encourage large-scale research efforts to overcome those knowledge gaps through appropriately granular longitudinal studies.

Early detection of dorsopathies is an urgent task for primary care physicians, since such conditions can combine with other chronic noncommunicable diseases (NСD) and adversely affect the course all comorbidities, consequently disimproving the quality of life of patients and increasing the frequency of their requests for medical assistance. This study aimed to determine the value of routine checkups in the context of detection of dorsopathies, NCD, and identification of risk factors (RF). We have retrospectively analyzed the patient records database of a rural outpatient clinic in the Tver region (years 2015 to 2017). The prevalence of dorsopathies and NCD RF were the subjects investigated. Fisher's exact test and Spearman's rank correlation coefficient (SRCC) were applied for the purposes of statistical processing of the results. We discovered that dorsopathy most often was a comorbidity to arterial hypertension and gastrointestinal tract diseases; it was strongly related to the NCD (SRCC = 0.506), age (SRCC = 0.383), slightly less so - to hypodynamia (SRCC = 0.146), type of the patient's occupation (intellectual or physical labor) (SRCC = 0.07). Routine checkups improve the rate of detection of dorsopathy: the more patients undergo such examinations, the more cases of dorsopathy are diagnosed. Thus, it is necessary to increase the number of working people attending the checkups in order to detect dorsopathies early and prevent them effectively.

To analyze the specifics of comorbidity forming and age-related correlations of the risk factors (RF) distribution in arterial hypertension (AH) patients living in rural areas. Material and methods. In 2015-2017 a retrospective analysis of 2500 patients database was done at two general practitioners offices in Konakovsky District of Tverskaya Oblast. Of those, 350 were selected (14%) at the age 44-53 (164 males, 186 females) among the charts containing most complete data on the dispanserization. Additionally, surveying of the group was done for more detailed retrospective analysis of comorbidity and RF existence during lifetime of 25-35 years. Results. In the structure of comorbidity AH predominates, which has been diagnosed in 50,86%of patients; mostly it is diagnosed at the age 44-53 (81,06%). After AH, 2nd place is held by dorsopathies (24%), 3rd - gastrointestinal disorders (12%). For chronic pulmonary obstructive disease and cerebrovascular disease - it is less than 3%. 96,1%of men with AH are smokers at the age 18 to 53 y. o. By the age 53, in 40,26%of men and 36,63%of women there is bodyweight increase; and raised cholesterol - in 48,05%and 22,77%, respectively. Conclusion. In rural areas inhabitants, the formation of comorbidity is ongoing mostly at age 44-53 y. o. Of the specifics of comorbidity in these patients, there is often combination of AH with dorsopathies, and quite rare - with chronic obstructive lung disease or cerebrovascular diseases. The observed at the age 34-43 "diagnostic gap" points on the necessity for attention to this exact age strata with the aim of ontime diagnostics and early stages of diseases reveal. The structure of RF during the lifetime is not homogenic and is the highest at the age of comorbidity forming (except smoking and professional harms). All the considered RF are more prominent in men than in women.
