Abstract
There have been numerous attempts to establish a correlation between obesity and stress, inflammatory, and dysmetabolism biomarkers in children and adolescents. Here, we performed a meta-analysis of existing studies to shed light on the elusive correlations of childhood and adolescent obesity with physiological indicators of stress, inflammation, and metabolism before and after lifestyle interventions. Observational studies, meta-analyses, narrative and systematic reviews were excluded. From a total of 53 articles, 11 were selected according to specific criteria. The biomarkers examined were circulating glucose, insulin, HDL, LDL, triglycerides, adiponectin, leptin, CRP, TNF-alpha, interleukin (IL)-6, systolic and diastolic blood pressure, and HOMA-IR. All analyses were performed using IBM SPSS Statistics Version 28.0.1.0 (142). The current meta-analysis provides evidence of a beneficial effect of a lifestyle intervention and/or drugs in children and adolescents living with obesity or overweight, consistent with a significant reduction in body fat-but not in BMI or waist circumference-an increase in circulating adiponectin and/or a reduction in serum insulin levels and diastolic blood pressure, and a trend towards a reduction of circulating leptin and glucose levels, as well as of the HOMA-IR. This meta-analysis indicates that lifestyle interventions could reduce overweight-/obesity-associated systemic inflammation and dysmetabolism even without an apparent decrease in BMI.

Abstract
Cafe-au-lait macules are the most distinctive clinical finding in neurofibromatosis type I. The aim of this prospective study of Greek children diagnosed with neurofibromatosis type I was to describe the dermatological phenotype and to analyse the characteristics of cafe-au-lait macules and their association with genotype. Pigment intensity and melatonin content of cafe-au-lait macules were measured with a narrowband spectrophotometer. A total of 63 children aged 6 months to 16 years old were studied. Mean melanin content varied, both among patients, and within each patient (p < 0.001). Females had a higher number of cafe-au-lait macules than did males (p = 0.025), and the melanin content of cafe-au-lait macules was lower in females than males (p < 0.001). Patients with protein-truncating variants in the neurofibromatosis type I gene had higher melanin content of cafe-au-lait macules than other types of genetic variants t (55) = 2.196, p = 0.032. Plexiform neurofibromas were also detected in the majority of patients with protein- truncating variants, while juvenile xanthogranulomas were detected equally in patients with protein-truncating and non-protein-truncating variants. In conclusion, cafe-au-lait macules with high melatonin content are associated with patients carrying non-protein-truncating variants. Therefore, measurement of cafe-au-lait macule pigment intensity might provide useful information for initial assessment of patients with neurofibromatosis type I and the severity of their future phenotype.

Abstract
OBJECTIVE To investigate the genetic etiology in a cohort of patients with a clinical, biochemical, and hormonal profile suggestive of a mild and transient form of PHA1. Patients - Methods: Twelve PHA1 patients with clinical and biochemical data were analyzed. The coding regions of NR3C2 and SCNN1A genes were sequenced. Human αENaC wt, αF226C and αF226S ENaC variants, were expressed in Xenopus laevis oocytes. to evaluate ENaC activity. The protein expression of α ENaC wt and mutants was determined by Western blot. RESULTS All patients were homozygotes for the p.Phe226Cys of the a subunit of ENaC, resulting in significantly reduced ENaC activity (83% reduction). Quantitative western blot analysis was consistent with a reduced ENaC protein expression for the αF226C compared to wt. CONCLUSIONS We present 12 patients from 4 different families with a mild and transient autosomal recessive PHA1 due to a novel homozygous missense mutation in the SCNN1A gene. Functional studies showed that the p.Phe226Cys substitution mutation in ENaC leads to a partial loss of function resulting mainly from both a decrease in the intrinsic ENaC activity, and a reduction in channel expression at the protein level. The partial loss of ENaC function could explain the mild phenotype, variable expressivity, and the transient course of the disorder in these patients.

Abstract
OBJECTIVES Long-term immunomodulatory therapy of pediatric onset-multiple sclerosis (POMS) is based mainly on published case series and internationally agreed guidelines. Relevant studies in the Greek population are absent from the literature. The purpose of this study is to present data on the efficacy and safety of the 1st line immunomodulatory drugs in the treatment of POMS patients. MATERIALS AND METHODS The present study included 27 patients meeting the IPMSSG criteria for POMS and who are monitored at the outpatient clinic of the Multiple Sclerosis and Demyelinating Diseases Unit (MSDDU), of the 1st Neurological Department, University Hospital of Aeginition. All patients received 1st line immunomodulatory drugs as initial therapy. Clinical, laboratory, and imaging parameters of the disease were recorded before and after treatment. RESULTS Post-treatment, a significant reduction of the relapse number (mean ± SD: 2.0 ± 1.0 vs 1.2 ± 1.6, p = 0.002), EDSS progression (mean ± SD: 1.5 ± 0.8 vs 0.9 ± 0.7, p = 0.005) and ARR (mean ± SD: 1.5 ± 0.7 vs 0.4 ± 0.5, p = 0.0001) was observed, while no changes were observed in the EDSS score, (mean ± SD: 1.8 ± 0.6 vs 1.9. 0.6, p = 0.60). Advanced age at treatment initiation increased the risk for drug discontinuation before 24 months of therapy (HR = 0.6, 95% CI (0.35-0.99), p = 0.04). CONCLUSIONS Most pediatric patients are forced to switch to either more efficacious 1st line or 2nd line drugs. Additionally, our study suggests that older age at the time of the 1st line treatment initiation, contributes to earlier drug discontinuation.

Abstract
Komiya et al recently sent a letter to the editor1 raising issues of reliability and validity of our study "Stress Management and in Vitro Fertilization (IVF): A Pilot Randomized Controlled Trial".2 Their comments focused on the default of the registration, the absence of any mention of case dropout, the ambiguity in the details of IVF treatment and the lack of specific figures on the background of the participants. However, the principles of CONSORT 2010 cannot be applied to Pilot Randomized and Feasibility Trials, only to Randomized Trials (RTs) or Randomized Controlled Trials (RCTs). Similarly, the CONSORT Extension 2016 suggested some principles for Pilot and Feasibility Trials, but again it does not directly apply to internal pilot studies, non-randomized pilot and feasibility studies, or phase II studies.3,4 Many international journals do not require registration for Pilot and Feasibility Trials, but only for RTs or RCTs,5 granted that clinical trial registration is not an indicator of low risk of bias.6 Thanks to the useful comments by Komiya et al, our article2 now includes online "Supplementary Materials" in which we clarify all their points one by one. Specifically, the Material and Method section of Supplementary Materials includes details for the Registration, the Flow Chart and the IVF Treatment, and the Results section includes details for the Background of the Participants. Thus, we believe that the level of reliability and validity of the study can be now examined and ensured.

Abstract
In recent years, research on exosomes and their content has been intensive, which has revealed their important role in cell-to-cell communication, and has implicated exosomal biomolecules in a broad spectrum of physiological processes, as well as in the pathogenesis of various diseases. Pregnancy and its normal progression rely highly on the efficient communication between the mother and the fetus, mainly mediated by the placenta. Recent studies have established the placenta as an important source of circulating exosomes and have demonstrated that exosome release into the maternal circulation gradually increases during pregnancy, starting from six weeks of gestation. This orchestrates maternal-fetal crosstalk, including maternal immune tolerance and pregnancy-associated metabolic adaptations. Furthermore, an increased number of secreted exosomes, along with altered patterns of exosomal non-coding RNAs (ncRNAs), especially microRNAs and long non-coding RNAs (lncRNAs), have been observed in a number of pregnancy complications, such as gestational diabetes mellitus and preeclampsia. The early detection of exosomes and specific exosomal ncRNAs in various biological fluids during pregnancy highlights them as promising candidate biomarkers for the diagnosis, prognosis and treatment of numerous pregnancy disorders in adolescents and adults. The present review aimed to provide insight into the current knowledge regarding the potential, only partially elucidated, role of exosomes and exosomal cargo in the regulation and progression of normal pregnancy, as well as their potential dysregulation and contribution to pathological pregnancy situations.

Abstract
Background: The COVID-19 pandemic has led to significant changes in the care of pregnant women and their fetuses. Emerging data show elevated depression and anxiety symptoms among pregnant women. Aims: The purpose of this article is to investigate the psychological and behavioral impact of the COVID-19 pandemic on pregnant women in Greece during the first national lockdown. Methods: We used a cross-sectional, anonymous survey to collect data in two fetal medicine clinics in the largest urban centers of Greece during the months of April and May 2020. The questionnaire was largely based on the CoRonavIruS Health Impact Survey (CRISIS), and assessed sociodemographic characteristics, general health and obstetric data and COVID-19-related worries and life changes. Mood symptoms, substance use and lifestyle behaviors were assessed at two time points (3 months prior to the pandemic and the 2 weeks before taking the survey), while perceived stress was measured with the perceived stress scale (PSS-14). Results: A total of 308 pregnant women (Mage = 34.72), with a mean gestation of 21.19 weeks participated in the study. Over one-third of the women found COVID-19 restrictions stressful, and their highest COVID-19-related worry was having to be isolated from their baby. Mean PSS-14 score was 21.94, suggesting moderate stress. The strongest predictors of stress were physical and mental health status before COVID-19 and having experienced a stressful life event during their pregnancy. Compared to 3 months before the pandemic, women reported higher scores on mood symptoms (p < 0.001), TV use (p = 0.01) and social media use (p = 0.031) in the last 2 weeks before taking the survey. Conclusion: Our study provides important preliminary evidence of the negative impact of the COVID-19 pandemic and the lockdown on pregnant women’s well-being and functioning.

Abstract
We investigated the presence of a molecular pathway from hepatic 11-βHSD-1 to brain MAO-A in the dynamics of plasma corticosterone involvement in anxiety development. During 14 days following repeated exposure of rats to predator scent stress for 10 days, the following variables were measured: hepatic 11-βHSD-1 and brain MAO-A activities, brain norepinephrine, plasma corticosterone concentrations, and anxiety, as reflected by performance on an elevated plus maze. Anxiety briefly decreased and then increased after stress exposure. This behavioral response correlated inversely with plasma corticosterone and with brain MAO-A activity. A mathematical model described the dynamics of the biochemical variables and predicted the factor(s) responsible for the development and dynamics of anxiety. In the model, hepatic 11-βHSD-1 was considered a key factor in defining the dynamics of plasma corticosterone. In turn, plasma corticosterone and oxidation of brain ketodienes and conjugated trienes determined the dynamics of brain MAO-A activity, and MAO-A activity determined the dynamics of brain norepinephrine. Finally, plasma corticosterone was modeled as the determinant of anxiety. Solution of the model equations demonstrated that plasma corticosterone is mainly determined by the activity of hepatic 11-βHSD-1 and, most importantly, that corticosterone plays a critical role in the dynamics of anxiety following repeated stress.

Abstract
INTRODUCTION Prematurity is associated with increased cardiometabolic risk later in life. The adipomyokine irisin has been acknowledged as a modulator of energy metabolism and insulin sensitivity. The aim of this study was to investigate circulating levels of irisin and their relation to anthropometric measurements and cardiometabolic phenotype in a population of preterm-born children versus full-term-born peers. METHODS A total of 160 children (87 born preterm aged 8.1-14.8 years and 73 born full-term of similar age and gender distribution) were studied. Arterial blood pressure, anthropometry, body composition assessments with dual energy X-ray absorptiometry, and skinfold measurements were performed. Blood biochemistry and circulating levels of irisin, insulin, cortisol, leptin, and adiponectin were also determined. RESULTS The preterm group had higher diastolic blood pressure, triceps skinfold, subscapular skinfold (SSSF), and abdominal skinfold measurements and more central adiposity than the full-term group. Irisin was significantly lower (p = 0.002), whereas leptin was higher (p = 0.03) in the preterm than the full-term group. Irisin correlated positively with gestational age (r = 0.19, p = 0.01), birth weight (r = 0.23, p = 0.003), and high-density lipoprotein cholesterol (r = 0.20, p = 0.01) and negatively with SSSF (r = -0.25, p = 0.003) and chronological age (r = -0.21, p = 0.008). CONCLUSION Lower levels of irisin and a slightly unhealthy adiposity and cardiometabolic pattern were detected in preterm-born children in comparison to their full-term-born peers. Whether low irisin levels in preadolescents and adolescents born prematurely could be of prognostic value for the development of cardiometabolic sequelae later in life remains to be further studied.

Abstract
INTRODUCTION Spastic paraplegia type 3 (SPG3) is a common autosomal dominant neurogenetic disease, presenting during childhood with symptoms of mildly progressive spasticity and weakness of the lower limbs. SPG3 develops due to mutations of the ATL1 gene that encodes atlastin-1, a GTPase crucial for the function of dendrites of corticospinal neurons. Here we present a case of preimplantation genetic testing for SPG3. PATIENT AND METHODS A 30-year-old woman with clinical symptoms of autosomal dominant spastic paraplegia since her first year of life asked for genetic counselling. DNA sequencing revealed the existence of mutation c.715C>T (p. R239C) in the ATL1 gene, confirming the diagnosis of SPG3. The patient asked for preimplantation testing for SPG3 after in vitro fertilization. An allele-specific method of PCR amplification was created in order to distinguish the mutant and the normal allele in the patient and her mother who also had SPG3, while her normal father served as control. The same nested PCR approach was used for the preimplantation testing of 11 available embryos. RESULTS The presence of the c.715C>T (p. R239C) mutation in the ATL1 gene was found in five embryos while six embryos carried normal alleles and were selected for IVF implantation. After three failed gestation attempts and one pregnancy ended by a spontaneous miscarriage in the first trimester due to a chromosomal abnormality, there was an achieved pregnancy with a totally normal embryo. CONCLUSION SPG3 may be degrading to a patient's quality of life; therefore, appropriate genetic counselling and preimplantation molecular testing may be provided as an option of prevention in offspring.

Abstract
Self-esteem constitutes a characteristic which can influence the person in many dimensions, depending on the perception positive or negative, which the individual has for himself/herself. The most usable tool for measuring self-esteem is the Rosenberg Self-Esteem Scale (RSES). In order to be validated in the Greek language in adolescents, the RSES was completed by 204 high school students, aged 12 to 18 years, at a private school in the suburbs of the region of Attica in Greece. Additional questionnaires were administered simultaneously, i.e., the Culture-Free Self-Esteem Inventories, Third Edition (CFSEI-3) and the Positive and Negative Affect Schedule (PANAS). The reliability and validity results of the RSES indicated satisfactory internal reliability index (Cronbach's a .89 and .80). The RSES showed good concurrent validity. Statistically significant relationships with academic performance and PANAS were observed. The Greek version of the RSES is short, easy to administer, and comprehensible by the teenagers and can be used for the measurement of self-esteem in adolescents in Greece.

Abstract
Stress has deleterious effects on brain health and yet, the prognostic value of psychosocial stress regarding the most common types of dementias, including Alzheimer disease, is still unclear. The primary aim of this systematic review was to explore the association between psychosocial stress and late onset dementia. We classified 24articles from Medline, PsycINFO, CINAHL, and Web of Science, as pertaining toxic categories of psychosocial and trauma-related stress (low socio-economic status [SES] related inequalities, marital status, posttraumatic stress disorder, work stress, "vital exhaustion" [VE], and, combined stressors). Using the Quality of Prognosis Studies in Systematic Reviews tool, we judged the quality of evidence to be low. This systematic review provided some non-robust, yet suggestive evidence that the above psychosocial types of stress are associated with increased risk of dementia in later life. Future robust, longitudinal studies with repeated validated measures of psychosocial stress and dementiaare required to strengthen or refute these findings.

Abstract
In contrast to studies of adults with emphysema, application of fixed thresholds to determine low- and high-attenuation areas (air-trapping and parenchymal lung disease) in pediatric quantitative chest CT is problematic. We aimed to assess age effects on: (i) mean lung attenuation (full inspiration); and (ii) low and high attenuation thresholds (LAT and HAT) defined as mean attenuation and 1 SD below and above mean, respectively. Chest CTs from children aged 6-17 years without abnormalities were retrieved, and histograms of attenuation coefficients were analyzed. Eighty examinations were included. Inverse functions described relationships between age and mean lung attenuation, LAT or HAT (p < 0.0001). Predicted value for LAT decreased from -846 HU in 6-year-old to -950 HU in 13- to 17-year-old subjects (cut-off value for assessing emphysema in adults). %TLCCT with low attenuation correlated with age (rs = -0.31; p = 0.005) and was <5% for 9-17-year-old subjects. Inverse associations were demonstrated between: (i) %TLCCT with high attenuation and age (r2 = 0.49; p < 0.0001); (ii) %TLCCT with low attenuation and TLCCT (r2 = 0.47; p < 0.0001); (iii) %TLCCT with high attenuation and TLCCT (r2 = 0.76; p < 0.0001). In conclusion, quantitative analysis of chest CTs from children without lung disease can be used to define age-specific LAT and HAT for evaluation of pediatric lung disease severity.

Abstract
The purpose of this study was to examine the effects of an 8-week stress management intervention to enhance resilience and coping techniques and decrease stress in adolescent students. Teenagers, 11 to 17 years old, recruited from two tertiary Adolescent Medicine Centers of the National and Kapodistrian University of Athens, Greece, were randomly assigned into two groups: the stress management group (n=24) and the control group (n=25). Resilience, stress, anxiety, everyday use of social media, school performance and cognitive skills were measured in adolescents of both groups, pre- and post-intervention. Post-intervention, the stress management group had significantly higher resilience scores and school performance self-evaluation scores, lower scores of stress, anxiety and everyday use of social media and better cognitive skills than the control group. Regarding cognitive skills, the stress management group significantly improved the speed of information processing and memory. Adolescents following stress management experienced significantly reduced stress from interacting with teachers/parents, from peer pressure, from school/leisure conflict as well as compulsive behaviours. With respect to resilience, the intervention improved adolescents' individual skills and resources, relationships with primary caregivers, and environmental factors that facilitated the sense of belonging. Future studies of large adolescent samples are required to evaluate the long-term benefits of stress management techniques on adolescents' health and resilience, as well as the need of continued support to preserve these benefits throughout transition to adulthood.

Abstract
INTRODUCTION The identification of pregnant women with Gestational Diabetes Mellitus (GDM) who will require insulin therapy, may modify their management to closer monitoring and probable early interventions. The aim of the study was to develop a predictive model for the necessity of insulin treatment in women with GDM. MATERIALS AND METHODS This was a prospective cohort study. Data from 775 women diagnosed with GDM per the IADPSG criteria were analyzed using logistic regression and a machine learning algorithm, the Classification and Regression Trees (CART). Potential predictors routinely recorded at follow-up visits were tested and used for the development of the model. The resultant model was externally validated using the data from two different perinatology clinics. RESULTS Preconceptional maternal BMI and morning fasting blood glucose levels at baseline and at 1 h during an Oral Glucose Tolerance Test (OGTT) were independent significant predictors for the treatment modality of GDM. Baseline blood glucose greater than 98 mg/dl and preconceptional maternal Body Mass Index (BMI) between 26 and 31 kg/height2 increased substantially the probability of insulin therapy (odds ratio [OR] 4.04, 95% confidence interval [CI] CI 2.65-6.17 and 2.21, 95%CI 1.42-3.43, respectively). The area under the curve (AUC) for the internal and external validation of the predictive model was 0.74 and 0.77, respectively. CONCLUSIONS A simple model based on maternal characteristics and the values of an OGTT can predict the need for insulin treatment with accuracy. Overweight women with an abnormal baseline blood glucose at OGTT are at high likelihood for insulin treatment. KEY MESSAGE Fifteen to 30% of women with Gestational Diabetes Mellitus (GDM) require insulin therapy. Overweight women with baseline blood glucose greater than 98 mg/dl at OGTT are at increased risk for insulin treatment and close monitoring and increased physical exercise are required.

Abstract
BACKGROUND The effectiveness of public health measures depends upon a community's compliance as well as on its positive or negative emotions. OBJECTIVE The purpose of this study was to perform an analysis of the expressed emotions in English tweets by Greek Twitter users during the first phase of the COVID-19 pandemic in Greece. METHODS The period of this study was from January 25, 2020 to June 30, 2020. Data collection was performed by using appropriate search words with the filter-streaming application programming interface of Twitter. The emotional analysis of the tweets that satisfied the inclusion criteria was achieved using a deep learning approach that performs better by utilizing recurrent neural networks on sequences of characters. Emotional epidemiology tools such as the 6 basic emotions, that is, joy, sadness, disgust, fear, surprise, and anger based on the Paul Ekman classification were adopted. RESULTS The most frequent emotion that was detected in the tweets was "surprise" at the emerging contagion, while the imposed isolation resulted mostly in "anger" (odds ratio 2.108, 95% CI 0.986-4.506). Although the Greeks felt rather safe during the first phase of the COVID-19 pandemic, their positive and negative emotions reflected a masked "flight or fight" or "fear versus anger" response to the contagion. CONCLUSIONS The findings of our study show that emotional analysis emerges as a valid tool for epidemiology evaluations, design, and public health strategy and surveillance.

Abstract
The objective of the study was to evaluate the psychological effect of an intervention of 8 stress-management sessions in women undergoing in vitro fertilization (IVF). Moreover, the overall IVF success was assessed against the fluctuation of the participants' stress levels. A total of 144 women participated in the study with 74 of them in the intervention group and 70 women in the control group. Demographics and medical history of all participants were recorded. The intervention group only underwent 8 weekly stress management sessions. During the 1st and 8th week of the study, both groups completed the Depression, Anxiety, Stress Scale 21 (DASS-21), the Perceived Stress Scale 14 (PSS-14) and the Fertility Problem Inventory (FPI). Following the intervention, the outcome of the IVF cycles, as defined by clinical pregnancy rates, were recorded. Our results indicated that total stress in the intervention group declined significantly (p<0.001) in respect to all the parameters of the PSS-14, DASS-21 and FPI scales, with the exception of the need for parenthood dimension that did not change significantly in the intervention group (p=0.002), while significantly increased in the control group (p<0.001). The difference of stress levels between the two groups for each scale as well as in total was also significant. There were no significant differences in the demographic data, lifestyle and medical history of the participants and their spouses between the two groups. The IVF success rate was found to be related to the levels of perceived stress on the PSS-14 scale (p=0.029) but not to any of the dimensions of DASS-21(p=0.197) and FPI (p=0.611) scales. Definitive factors affecting the IVF success were the participants' age (p=0.046), which was negatively correlated to IVF success, and the spouses' medical history of cryptorchidism (undescended testicles) (p=0.05). The high significance of these variables probably limited the effect of the intervention for stress relief on IVF success. This pilot study revealed encouraging results regarding the positive effect of interventions for stress management in women undergoing fertility treatment, however the possible contribution of such interventions to overall IVF success rates requires further investigation.

Abstract
This systematic review aimed to investigate the inconsistency of research data concerning the contribution of systematic psychosocial interventions to infertility treatments. More specifically, the objective of this review was to investigate the cause of the contradictions in the results of contemporary research with respect to the role of systematic psychosocial interventions in the success of fertility treatments. The suspected cause of these contradictions is the heterogeneity of the relevant clinical studies with respect to their methodology. Thus, the specific aim of the current review was to evaluate the degree of heterogeneity of certain parameters in the design of the relevant clinical studies during the last decade, including sample heterogeneity, assisted reproductive technology methods, types of psychosocial interventions and methods of recording and analyzing psychometric data. This investigation may be considered imperative considering that despite the great number of relevant clinical studies and their meta-analyses, there are still no conclusive results concerning the potential of improving fertility through psychosocial support. Search for relevant studies was performed employing the PubMed and Google Scholar databases based on specific criteria. According to these criteria the selected publications have been meta-analyses of clinical studies on humans, evaluating the effect of psychosocial interventions on the success of assisted reproductive treatments during the last decade. The studies may have included all the different infertility etiologies, as well as all types of assisted reproductive treatments. The extensive search based on the specific inclusion/exclusion criteria resulted in reporting results from 6 studies in total. The clinical studies included have reported on various types of interventions for psychosocial support such as individual, couples' or group therapies performed either in facilities offering mental health services or in the form of home-based self-treatment. Moreover, these studies investigated various techniques of stress management ranging from counseling to specialized methods such as biofeedback and diaphragmatic breathing or alternative techniques such as yoga and meditation. Our results suggest that clinical studies designed specifically to evaluate the effect of systematic interventions on the efficacy of fertility treatments are limited. Moreover, their degree of heterogeneity is highly significant with respect to included participants, treatment protocols, psychosocial support techniques as well as methods for the documentation and statistical analysis of psychometric data. Consequently, the conduction of well-design clinical studies based on strict criteria aiming to investigate specific infertility causes, similar fertility treatment protocols or particular types of psychosocial interventions is necessary in order to reach definitive conclusions.

Abstract
Primary aldosteronism (PA) is the most common endocrine cause of arterial hypertension. Despite the increasing incidence of hypertension worldwide, the true prevalence of PA in hypertension was only recently recognized. The objective of the work was to estimate the prevalence of PA in patients at different stages of hypertension based on a newly developed screening-diagnostic overnight test. This is a prospective study with hypertensive patients (n=265) at stage I (n=100), II (n=88), and III (n=77) of hypertension. A group of 103 patients with essential hypertension without PA was used as controls. PA diagnosis was based on a combined screening-diagnostic overnight test, the Dexamethasone-Captopril-Valsartan Test (DCVT) that evaluates aldosterone secretion after pharmaceutical blockade of angiotensin-II and adrenocorticotropic hormone. DCVT was performed in all participants independently of the basal aldosterone to renin ratio (ARR). The calculated upper normal limits for post-DCVT aldosterone levels [3 ng/dl (85 pmol/l)] and post-DCVT ARR [0.32 ng/dl/μU/ml (9 pmol/IU)] from controls, were applied together to establish PA diagnosis. Using these criteria PA was confirmed in 80 of 265 (30%) hypertensives. The prevalence of PA was: 21% (21/100) in stage I, 33% (29/88) in stage II, and 39% (30/77) in stage III. Serum K+ levels were negatively correlated and urinary K+ was positively correlated in PA patients with post-DCVT ARR (r=-0.349, p <0.01, and r=0.27, p <0.05 respectively). In conclusion, DCVT revealed that PA is a highly prevalent cause of hypertension. DCVT could be employed as a diagnostic tool in all subjects with arterial hypertension of unknown cause.

Abstract
'Snow White and the Seven Dwarfs', a fairytale that is widely known across the Western world, was originally written by the Brothers Grimm, and published in 1812 as 'Snow White'. Though each dwarf was first given an individual name in the 1912 Broadway play, in Walt Disney's 1937 film 'Snow White and the Seven Dwarfs', they were renamed, and the dwarfs have become household names. It is well known that myths, fables, and fairytales, though appearing to be merely children's tales about fictional magical beings and places, have, more often than not, originated from real facts. Therefore, the presence of the seven brothers with short stature in the story is, from an endocrinological point of view, highly intriguing, in fact, thrilling. The diversity of the phenotypes among the seven dwarfs is also stimulating, although puzzling. We undertook a differential diagnosis of their common underlying disorder based on the original Disney production's drawings and the unique characteristics of these little gentlemen, while we additionally evaluated several causes of short stature and, focusing on endocrine disorders that could lead to these clinical features among siblings, we have, we believe, been able to reveal the underlying disease depicted in this archetypal tale.

Abstract
BACKGROUND Aquagenic wrinkling of the palms (AWP) is an excessive and early palmar wrinkling occurring after Brief Immersion to Water (BIW), and has been reported as a frequent finding among cystic fibrosis (CF) patients. OBJECTIVES To evaluate and assess the diagnostic performance of BIW test as an initial screening tool for CF diagnosis. METHODS We measured AWP in CF patients, CF-heterozygotes (CF-het) and normal controls. The AWP parameters of palmar wrinkling, oedema, papules, pruritus and pain were assessed at 3, 7 and 11 min after a BIW test was performed for all the participants. Statistical analyses explored the progression of AWP in time for the three groups and assessed the diagnostic performance of BIW test as a diagnostic screening tool for CF. RESULTS A total of 250 individuals (100 CF patients, their 50 CF-het parents, 100 healthy controls) were included in the analysis. The average age in years (mean ± SD) was 10.4 ± 4.0 for CF, 35.9 ± 6.1 for CF-het and 10.5 ± 4.0 for controls. The rate of positives for AWP at 3 min among CF patients, CF-het and controls was 68%, 8% and 0%, respectively (P < 0.01). Kaplan-Meier analysis showed a clear trend towards earlier appearance of all five parameters in the direction controls < hetCF < CF (P values <0.01). The best diagnostic performance in detecting between CF patients and non-CF was achieved by the presence of papules and wrinkling at 7 min (sensitivity/specificity: 94.0%/98.3% and 100.0%/92.0%, respectively). CONCLUSIONS A strong association between AWP and CF was detected. AWP after BIW could be elicited easily and possibly can be used as an initial screening tool to assess if an individual with symptoms and signs that raise the likelihood of CF is a CF patient.

Abstract
Background Functional constipation (FC) is the most common gastrointestinal disorder of childhood and has a multifactorial etiology. We aimed to assess dietary habits in Greek children with FC compared to the general population (control group, CG). Methods This was a subgroup analysis of a school-based, cross-sectional study carried out in children 6-18 years of age, between January and June 2014, using the Rome III criteria for the diagnosis of FC. Dietary parameters, as well as socioeconomic and demographic data and their association with the likelihood of FC, were analyzed through multivariate logistic regression analysis and expressed as odds ratios (OR). Results A total of 1439 children (1218 CG, 221 FC) were included in the analysis. The final model showed that consumption of was the only dietary parameter significantly related to FC; higher frequency of consumption was inversely related to the likelihood of FC (OR: 0.98, 95% CI: 0.96, 0.99, P=0.048). Significant socioeconomic confounders with a positive association with FC were: parental educational level, victimization, physical activity and number of adults at home. Conclusions Increased frequency of fiber consumption is significantly associated with higher odds of FC irrespective of socioeconomic background and lifestyle parameters. Interventional studies are required to validate these cross-sectional observations.

Abstract
Pediatric cancer and its treatment may have an impact on the neurocognitive functions of childhood cancer survivors (CCS). The aim of the present meta-analysis was to compare the intelligence quotient (IQ) scores between CCS of acute lymphoblastic leukemia (ALL) and controls. A comprehensive electronic search identified original research articles that reported scores of the Wechsler Intelligence Scale (WISC; WISC-III, WISC-IV and WISC-R) for children and adolescents, aged 6-16 years at evaluation, survivors of ALL and healthy controls. The included CCS had completed anticancer treatment and were in remission at the time of assessment. A total of 16 studies were included in the meta-analysis, out of 128 extracted studies, and involved a total of 1,676 children and adolescents: 991 CCS (ALL) and 685 healthy controls. Among the studies, a random effects model revealed a moderate estimate of effect size [standardized mean difference (SMD), -0.78; 95% CI, -1.05 to -0.50], indicating that the WISC scores for total IQ were significantly lower in the CCS than in the controls. The mean total IQ range was 85.2-107.2 in the CCS and 88.4-114.1 in the controls. The difference in the mean total IQ between controls and CCS ranged from -13.8 to 20.6. As regards the WISC scores for verbal IQ, 11 studies were included. A random effects model revealed a moderate estimate of effect size (SMD, -0.71; 95% CI, -1.05 to -0.38), indicating that the WISC scores for verbal IQ were significantly lower in the CCS than in the controls. Among the 9 studies that had available data for performance IQ scores, a fixed effect model revealed a moderate estimate of effect size (SMD, -0.80; 95% CI, -1.09 to -0.52), indicating that the WISC scores for performance IQ were significantly lower in the CCS than in the controls. As the survival rates of children and adolescents with ALL are steadily increasing, regular, lifelong follow-up for neurocognitive late effects is imperative in order to improve their education and employment prospects and overall, their quality of life.

Abstract
Mayer-Rokitansky-Küster-Hauser syndrome (MRKHS) is associated with congenital absence of the uterus, cervix, and the upper part of the vagina; it is a sex-limited trait. Disrupted development of the Müllerian ducts (MD)/Wölffian ducts (WD) through multifactorial mechanisms has been proposed to underlie MRKHS. In this study, exome sequencing (ES) was performed on a Chinese discovery cohort (442 affected subjects and 941 female control subjects) and a replication MRKHS cohort (150 affected subjects of mixed ethnicity from North America, South America, and Europe). Phenotypic follow-up of the female reproductive system was performed on an additional cohort of PAX8-associated congenital hypothyroidism (CH) (n = 5, Chinese). By analyzing 19 candidate genes essential for MD/WD development, we identified 12 likely gene-disrupting (LGD) variants in 7 genes: PAX8 (n = 4), BMP4 (n = 2), BMP7 (n = 2), TBX6 (n = 1), HOXA10 (n = 1), EMX2 (n = 1), and WNT9B (n = 1), while LGD variants in these genes were not detected in control samples (p = 1.27E-06). Interestingly, a sex-limited penetrance with paternal inheritance was observed in multiple families. One additional PAX8 LGD variant from the replication cohort and two missense variants from both cohorts were revealed to cause loss-of-function of the protein. From the PAX8-associated CH cohort, we identified one individual presenting a syndromic condition characterized by CH and MRKHS (CH-MRKHS). Our study demonstrates the comprehensive utilization of knowledge from developmental biology toward elucidating genetic perturbations, i.e., rare pathogenic alleles involving the same loci, contributing to human birth defects.

Abstract
Background The World Health Organization named the phenomenon of misinformation spread through social media as an “infodemic” and recognized the need to curb it. Misinformation infodemics undermine not only population safety but also compliance to the suggestions and prophylactic measures recommended during pandemics. Objective The aim of this pilot study is to review the impact of social media on general population fear in “infoveillance” studies during the COVID-19 pandemic. Methods The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) protocol was followed, and 6 out of 20 studies were retrieved, meta-analyzed, and had their findings presented in the form of a forest plot. Results The summary random and significant event rate was 0.298 (95% CI 0.213-0.400), suggesting that social media–circulated misinformation related to COVID-19 triggered public fear and other psychological manifestations. These findings merit special attention by public health authorities. Conclusions Infodemiology and infoveillance are valid tools in the hands of epidemiologists to help prevent dissemination of false information, which has potentially damaging effects.

Abstract
There is evidence that children with neurodevelopmental disorders may exhibit atypical responses to stress and alterations in concentrations and diurnal secretion of stress hormones. We assessed diurnal profiles and stress responses of salivary cortisol and alpha-amylase (sAA) in children with attention-deficit hyperactivity disorder (ADHD), autism spectrum disorder (ASD) and specific learning disorder (SLD) compared to typically developing children (TD). A total of 157 children of both sexes, aged between 6 and 12 years old, took part in the study distributed into four groups: ADHD (N = 34), ASD (N = 56), SLD (N = 43) and TD (N = 24). Salivary samples were collected at three time points during a day, as well as before and 5 min after an academic performance test and a moral cognition task. ADHD children had lower evening and diurnal sAA levels, adjusted for age. Also, ASD children showed lower diurnal sAA secretion, adjusted for age. The mean percentage change for salivary cortisol and sAA after both tests did not differ between the groups. In conclusion, we demonstrated alterations in diurnal autonomic functioning in children with ADHD and ASD, while hypothalamic-pituitary-adrenal axis functioning did not differ between the clinical and the comparison groups.

Abstract
Diabetes mellitus can independently contribute to cardiovascular disease and represents a severe risk factor for premature development of cardiovascular disease. A three-fold higher mortality than the general population has been observed in type 1 diabetes mellitus whereas a two- to four-fold increased probability to develop cardiovascular disease has been observed in type 2 diabetes mellitus. Cardiovascular magnetic resonance, a non-radiative modality, is superior to all other modalities in detecting myocardial infarction. The main cardiovascular magnetic resonance sequences used include a) balanced steady-state free precession (bSSFP) for function evaluation; b) T2-W for oedema detection; c) T1 W for ischemia detection during adenosine stress; and d) late gadolinium enhanced T1-W images (LGE), evaluated 15 min after injection of paramagnetic contrast agent gadolinium, which permit the diagnosis of replacement fibrosis, which appears white in the middle of suppressed, nulled myocardium. Although LGE is the technique of choice for diagnosis of replacement fibrosis, it cannot assess diffuse myocardial fibrosis. The application of T1 mapping (native or pre contrast and post contrast) allows identification of diffuse myocardial fibrosis, which is not detectable my other means. Native T1 and Contrast-enhanced T1 mapping are involved in the extracellular volume fraction (ECV) calculation. Recently, 1H-cardiovascular magnetic resonance spectroscopy has been applied to calculate the amount of myocardial triglycerides, but at the moment it is not part of the routine assessment of diabetes mellitus. The multifaceted nature of cardiovascular magnetic resonance has the great potential of concurrent evaluation of function and myocardial ischemia/fibrosis in the same examination and represents an indispensable tool for accurate diagnosis of cardiovascular disease in diabetes mellitus.

Abstract
BACKGROUND There is an endless debate on whether androgens mediate testis descent through developmental changes in the gubernacular or the cranial suspensory ligament. OBJECTIVE To investigate the relation of any possible morphologic changes in the genital mesentery, that is, the system of genital peritoneal folds including the gubernacular and cranial suspensory ligaments, with the event of testis non-descent in rats prenatally exposed to the antiandrogen flutamide. MATERIALS AND METHODS Time-pregnant Sprague Dawley rats received flutamide (100 mg/kg/d) or vehicle subcutaneously on gestational days 16-17. Flutamide-treated male offspring (n = 67), and vehicle-treated male (n = 34) and female (n = 28) offspring were surgically explored under microscope on postnatal day 50. Testicular position was examined bilaterally. Dimensions of genital mesentery parts were also assessed bilaterally. Association of flutamide-induced morphologic changes with descended (n = 61) and undescended (n = 50; 33 cryptorchid and 17 ectopic) testes was investigated with logistic regression analysis. RESULTS The male genital mesentery comprised a cranial and a caudal fold converging on the vas deferens. Flutamide resulted in enlarged cranial and reduced caudal folds. Of all flutamide-induced alterations, the increased length of the posterior fixation of the cranial fold and the decreased length of the gubernacular ligament of the caudal fold were found to independently increase the odds of testis non-descent. Testicular ectopy, unlike cryptorchidism, was associated with a short gubernacular ligament only. The female genital mesentery consisted of a cranial fold only. CONCLUSION Our findings showed a combined contribution of both cranial and caudal folds of the genital mesentery to testis non-descent, through an abnormally long mesentery root and an abnormally short gubernacular ligament, respectively. Inhibition of male-specific development of the genital mesentery with flutamide did not result in a feminized architecture.

Abstract
OBJECTIVE To examine the validity and the reliability of a novel measurement tool, the Newly Diagnosed Breast Cancer Stress Scale (NDBCSS) in the Greek population. The tool aimed to assess distress in patients recently diagnosed with breast cancer. METHODS We performed a principal component analysis (PCA) of the 17 items of the scale. RESULTS The PCA resulted in 4 factors: 1. Personal life, 2. Procedural issues, 3. Facing challenges and 4. Psychological load. All subscales showed satisfactory internal consistency and variance, relative to theoretical score ranges. Subscale scores and total score were significantly correlated with perceived stress and hospital anxiety and depression scale, implying good criterion validity. Associations with social, demographic and disease related information were also found. CONCLUSIONS The NDBCSS resulted in acceptable reliability and good validity, and was considered as a valuable tool for health-care workers and oncologists to measure psychological distress in early stage of breast cancer.

Abstract
Multiple sclerosis (MS) is a multifactorial, chronic, immune-mediated, and neurodegenerative disease, having a well-known hypothalamic-pituitary-adrenal (HPA) axis dysfunction. Several hormones have a great impact in the immune dysregulation, psychology, and cognitive status of patients with MS, as also in the fertility and response to treatment. In this comprehensive review, as an introduction, we mention basic data concerning MS: epidemiology, genetics, immunogenetics, epigenetics, pathophysiology, and neuroimmunology. Hormonal components of the disease cascade, mainly glucocorticoids (stress-related hormone), estrogens, prolactin and dehydroepiandrosterone (sex-related hormones), melatonin, and vitamin D, are discussed, aiming at focusing on core data regarding the impact of these hormones in MS pathophysiology, severity of the disease, correlation with comorbid mental disorders, and fertility. A great focus is given in the pre- and post-pregnancy period of MS patients, in the context of the disease-modifying treatments (DMTs) and HPA status, having in mind that there are only very limited knowledge and few papers on this specific life period of these women, having MS. All this data are presented in the main text and also in the workable tables, for the first time, suggesting targeted topics that need to be addressed in the near future.

Abstract
The novel coronavirus SARS-CoV-2 has emerged as a severe threat against public health and global economies. COVID-19, the disease caused by this virus, is highly contagious and has led to an ongoing pandemic. SARS-CoV-2 affects, mainly, the respiratory system, with most severe cases primarily showcasing acute respiratory distress syndrome. Currently, no targeted therapy exists, and since the number of infections and death toll keeps rising, it has become a necessity to study possible therapeutic targets. Antiviral drugs can target various stages of the viral infection, and in the case of SARS-CoV-2, both structural and non-structural proteins have been proposed as potential drug targets. This review focuses on the most researched SARS-CoV-2 proteins, their structure, function, and possible therapeutic approaches.

Abstract
OBJECTIVE The cognitive mechanisms (especially the gender-related ones) underlying optical illusion processing remain elusive. Since the N400 component of event-related potentials (ERPs) is an index of the semantic integration of information processing tasks, the present study focuses on gender-related differences in N400 waveforms elicited during the reasoning process applied to reach a valid conclusion of optical illusions engaging working memory (WM). APPROACH Fifty-one healthy participants (28 males, age = 34.25 years ± 10.25, years of education = 16.00 years ± 1.78; and 23 females, age = 33.43 ± 7.93, years of education = 15.56 ± 1.82) were measured. The N400 ERP component was evoked by 39 optical illusions adjusted to induce WM. We compared brain activation patterns while participants maintained conclusions of the optical illusions in WM. The N400 of ERPs was recorded during the WM phase, during which participants were required to draw a logical conclusion regarding the correctness of the optical illusions. MAIN RESULTS Analysis revealed that females compared to males exhibited significantly increased N400 amplitudes located at parietal and occipital sites, whereas males exhibited significantly higher N400 amplitudes located at frontal areas. Furthermore, females compared to males demonstrated significantly prolonged latencies of the N400 component located at right frontotemporal abductions. SIGNIFICANCE These results suggest that coupling of optical illusions with WM engages distinct gender-related variations of brain semantic processing as reflected by the N400 ERP component. Based on the dual process account, our study gives support to the notion that women tend to employ a more deliberate and slower semantic reasoning than the men who tend to employ an automatic and fast one. Topographically, within the network sub-serving the semantic operation, the posterior brain areas responsible for sensorimotor integration-related processes elicit a greater brain activation among females while the anterior brain areas responsible for control and storage/retrieval operation elicit a greater brain activation among males.

Abstract
Background: Mapping time-structures is a burgeoning scientific field enriching the (P4) medicine models. Local evidence in Mediterranean populations is underinvestigated. Methods: The Censused stroke-related death events (D) in the largest East-Mediterranean port (Piraeus), during (1985-1989), when local population had diet (low fat/sugar, proteins and vegetables/fruits daily, and pure olive oil almost exclusively) and genetic homogeneity-later interrupted by the immigration into Greece in 1990; and Sunspot numbers were indexed by Wolf numbers (Rz) (1944-2004), and evaluated using Fast Fourier Analysis and Singular Spectrum Analysis in MATLAB. Results: D were turned with fluctuations >35% in Rz. A non-anthropogenic 6.8 days cycle was recognized. Conclusions: This study may be taken into consideration in future public health planning and chronotherapy evaluations.

Abstract
BACKGROUND Previous evidence associating ileocecal valve removal (ICVR) with a reduced risk of fecal impaction of the ileocecum in cystic fibrosis indicated possible benefits from ileocecal valve loss in disorders with inhibited proximal colon transit caused by fecal dehydration and hypoperistalsis. We aimed to investigate the ability of ICVR in reversing fecal impaction in a loperamide-induced model of a similar pattern of inhibited proximal colon transit in rats. MATERIALS AND METHODS Thirty pubertal Sprague-Dawley rats were rendered constipated with subcutaneous loperamide treatment (1 mg/kg/d) for 7 d. On day four, rats were allocated to groups: ICVR (n = 12), total colectomy (TC, n = 9), and sham operation (SO, n = 9). Fecal pellet number and consistency were assessed daily. On day seven, all rats were gavaged with barium. Two hours later, intestinal transit ratio (distance of barium head from the pylorus adjusted for small intestine length) and adjusted (for total intestine length) barium-to-anus distance were assessed. RESULTS ICVR showed higher transit ratio and shorter barium-to-anus distance, that is, faster transit, than SO (P < 0.0001); differences between ICVR and TC were not significant (P > 0.06). Furthermore, ICVR and TC showed similar reduction in hard feces, compared with SO (P < 0.0001). TC showed higher diarrhea rate than ICVR (P < 0.0001). CONCLUSIONS ICVR led to an effective, similar to TC, reversal of the constipating effects of loperamide and, unlike TC, was not associated with diarrhea. Our findings support the idea that ICVR might be beneficial in disorders with inhibited proximal colon transit resulting from fecal dehydration and hypoperistalsis, such as refractory cystic fibrosis-related intestinal obstruction. Potential clinical implications merit further study.

Abstract
School bullying is increasingly recognized as an important factor affecting both individual's wellbeing and social functioning. Several studies provide evidence for the potential role of contextual factors that relate to bullying victimization such as the socioeconomic status of the parents/ family, the quality of family and home environment, the school climate, structure and ethos, and also various community characteristics. The objectives of this school-based, cross-sectional study were to report the prevalence of the perception of being bullied in a sample of Greek children and adolescents from 6 to 17 years of age and to investigate the relations among the subjective impression of bullying victimization and several sociodemographic and socioeconomic factors. We hypothesized that influences external to individual children and adolescents play a decisive role to their perception of being victimized. Bullying victimization was measured through a simple "yes/no" question, which confirmed or rejected respectively the fact that the child or adolescent has been at some time victimized in the school environment. Also, demographic and socioeconomic data about the families of children and adolescents were collected. A total of 1,588 children (51.8% females, mean age ± SD: 12.9±2.8 years) were assessed. The overall prevalence of victimization was 10.4%. Multiple logistic regression analysis on the probability of being victimized identified that living at a main urban center (Odds Ratio[OR]: 2.63, CI: 1.78-3.87, p<0.001), presence of a person with a chronic illness at home (OR: 1.90, CI: 1.12-3.20, p=0.016), poor family economic status (OR: 1.83, CI: 1.05-3.20, p=0.032),and increased number of adults at home (OR: 2.00, CI: 1.00-3.77, p=0,041) had a positive correlation with the prevalence of reported bullying victimization. Moreover, higher parental educational level related to lower probability of victimization (OR: 0.88, CI: 0.78-0.99, p=0.05). These findings demonstrate that several demographic and socioeconomic factors play a potential role in bullying victimization among schoolchildren. Our results also highlight the need to consider the influence of contextual factors in the design of targeting efforts countering and/or preventing bullying victimization.

Abstract
Background Pediatric-onset multiple sclerosis (POMS) is considered a complex disease entity with many genetic and environmental factors implicated in its pathogenesis. Linkage studies in Caucasian adult populations consistently demonstrate the major histocompatibility complex and its HLA (human leukocyte antigen) polymorphisms as the genetic locus most strongly linked to MS. Objective To investigate the frequencies and possible clinical and imaging correlations of HLA-DRB1 alleles in a Hellenic POMS sample. Methods Fifty POMS patients fulfilling the IPMSSG (International Pediatric Multiple Sclerosis Study Group) criteria were enrolled using 144 adult-onset MS (AOMS) patients and 246 healthy controls for comparisons. HLA genotyping was performed with standard low-resolution sequence-specific oligonucleotide (SSO) techniques. Clinical and imaging correlations with specific HLA-DRB1 alleles were also examined. Results The HLA-DRB1*03 genotype was significantly higher in POMS patients compared to both the AOMS population (26% vs. 12.5%, p = 0.042) and the general population (26% vs. 12.6%, p = 0.004). HLA-DRB1*03-positive POMS patients had significantly more relapses (6.9 ± 4.9 vs. 4.2 ± 4.4, p = 0.005) and more thoracic spinal cord lesions than HLA-DRB1*03-negative patients (61.5% vs. 27%, p = 0.043). Conclusion In our Hellenic population, HLA-DRB1*03 allele confers increased risk for POMS and it is also correlated with possibly increased disease activity, expanding the existing knowledge on HLA associations and POMS.
