Evaluation of nutritional status of young adolescents diagnosed with Down syndrome: a descriptive study

Evaluation of nutritional status of young adolescents diagnosed with Down syndrome: a descriptive study

Energy and nutrient intake by 11-13-year-old young adolescents attending private schools in Delhi, India.

There are no high-quality data on dietary behaviour of adolescents in India. This study aimed to assess the intake of energy (E), macronutrients and selected micronutrients in a sample of 11-13-year-old schoolchildren in Delhi, India. Participants from private schools (n=10) recorded dietary intake using a 3-d food diary. Information was entered into the dietary assessment tool, Intake24, to ascertain portion size and convert data into nutrient intake through integrated food tables. Of the 514 consenting participants, 393 (76·4 %) (169 girls, 224 boys) aged 11·4 (±1·8) years completed the study. The median (interquartile range (IQR) daily E intake was 2580 (2139·3-2989·8) kcal (10·8 (9·0 - 12·5) MJ) for girls and 2941·5 (2466·7-3599·3) kcal (12·3 (10·3-15·2) MJ) for boys. The median (IQR) daily nutrient intakes for girls and boys respectively were protein 64·6 (54·8-79·3) g, 74·4 (61·4; 89·4) g; carbohydrate 336·5 (285·3-393·6) g, 379·6 (317·8-461·8) g; and saturated fat 45·6 (34·8-58·3) g, 54·6 (41·9-69·5) g. There were no significant between-gender differences in percentage E from protein (10·2 (9·2-11·4)), or carbohydrate (52·4 (48·7-56·7)). Girls obtained less percentage E from saturated fat (16·1 (11·0-18·2) compared with boys 16·3 (14·2-19·1) (P < 0·05). E from saturated fat was above FAO recommendations in >74 % of participants. The estimated average requirement for iron was achieved by < 40 % of girls. In conclusion, strategies to optimise the dietary intake of adolescents in India should focus on preventing excess intakes of E and saturated fat and improving iron intake in girls.

Task–Rest Reconfiguration Efficiency of the Reward Network Across Adolescence and Its Association With Early Life Stress and Depressive Symptoms

Adolescents face significant changes in many domains of their daily lives that require them to flexibly adapt to changing environmental demands. To shift efficiently among various goals, adolescents must reconfigure their brains, disengaging from previous tasks and engaging in new activities. To examine this reconfiguration, we obtained resting-state and task-based functional magnetic resonance imaging (fMRI) scans in a community sample of 164 youths. We assessed the similarity of functional connectivity (FC) of the reward network between resting state and a reward-processing state, indexing the degree of reward network reconfiguration required to meet task demands. Given research documenting relations among reward network function, early life stress (ELS), and adolescent depression, we examined the association of reconfiguration efficiency with age across adolescence, the moderating effect of ELS on this association, and the relation between reconfiguration efficiency and depressive symptoms. We found that older adolescents showed greater reconfiguration efficiency than younger adolescents and, furthermore, that this age-related association was moderated by the experience of ELS. These findings suggest that reconfiguration efficiency of the reward network increases over adolescence, a developmental pattern that is attenuated in adolescents exposed to severe ELS. In addition, even after controlling for the effects of age and exposure to ELS, adolescents with higher levels of depressive symptoms exhibited greater reconfiguration efficiency, suggesting that they have brain states at rest that are more strongly optimized for reward processing than do asymptomatic youth. We worked to ensure race, ethnic, and/or other types of diversity in the recruitment of human participants. We worked to ensure sex and gender balance in the recruitment of human participants. We worked to ensure that the study questionnaires were prepared in an inclusive way. One or more of the authors of this paper self-identifies as a member of one or more historically underrepresented racial and/or ethnic groups in science.

Problematic use of WhatsApp and adolescents: What educational role do parents play?

The goal of this study is to understand the relationship between the problematic use of WhatsApp among young adolescents and parental mediation. The rise of mobile phone use among young people is a cause for concern, especially among parents themselves. The literature suggests that parents have a certain amount of room for maneuver through different parental strategies (parental mediation) to maximize the benefits of technology and reduce its possible risks, although this has not been sufficiently analyzed in the case of problematic use of the mobile phone and its applications. This study therefore examined three different parental mediation strategies (restrictive, modeling and stimulation) and their possible impact on the problematic use of WhatsApp. The sample comprised 1,144 13- and 14-year-old students during three academic years (2015-2018) in 17 schools in 7 Spanish provinces. One of the novelties of the study was the use of adolescent voices to understand the parental mediation of their parents. The results showed a direct relationship between the level of restrictive mediation and a problematic use of WhatsApp. In addition, the number of mobile phones that students have enjoyed, as well as whether parents use their mobile phone during dinner, also has a positive relationship with the problematic use of WhatsApp. These results are useful for understanding a responsible use of the mobile phone, as well as to guide parents about the problematic use of WhatsApp among adolescents.

Adolescent sexual and reproductive health literacy needs: a sub-national level assessment in Ghana.

This study assessed young adolescents' access and literacy challenges to sexual and reproductive health information and knowledge gaps in the Effutu Municipality in the Central Region of Ghana. We used a narrative design and a focus group discussion method to glean data from 52 in-school adolescents, aged 11-15. Focus group discussions were conducted using a discussion guide and data were processed using QDA Miner (version 6.0). We analyzed data thematically using an iterative process of data validation, coding and recording. The participants had poor knowledge of the concepts of sexual and reproductive health and its essential domains. Abstinence was the predominant sexual and reproductive health goal of the participants. Yet, many males admitted to having sexual partners. There was difficult linguistic and physical access to structured and safe information. Personal hygiene, signs of sexual maturation and abstinence were the predominant contents available to young adolescents. A revision of adolescent health policies and strategies to embrace actions for improving unrestricted access to easy-to-read educational materials and adolescent health literacy is essential. Creating adolescent corners and introducing peer education in schools within Effutu and other municipalities in the Central Region will be useful.

Evidence for Environmental Risk Factors and Cumulative Stress Linking Racial/Ethnic Identity and Psychotic-Like Experiences in ABCD Study Data

Previous work has found increased endorsement of psychotic-like experiences (PLEs) among marginalized racial and ethnic groups. According to social determinants frameworks, marginalized groups are at increased risk for exposure to socio-environmental risk factors, including systemic factors (eg, poverty and poor housing conditions) and social stressors (eg, discrimination). We examine the extent to which environmental risk factors and stress account for associations between racial/ethnic groups with PLEs. Analyses included 11,876 young adolescents 9 to 10 years of age from the Adolescent Brain Cognitive Development (ABCD) study. Mediation models assessed whether stress at 1-year follow-up indirectly linked baseline environmental risk to later distressing PLEs at 2-year follow-up. Serial mediation models examined whether environmental risk and stress indirectly accounted for variation among racial/ethnic groups in self-reported distressing PLEs. Through principal component and mediation analyses, we found evidence that the link between environmental risk (eg, poverty and exposure to crime) and distressing PLEs was mediated by stress. There was also evidence that higher endorsement of distressing PLEs within the Black and Hispanic groups was serially mediated by greater environmental risk and greater stress. The analyses provide evidence that the associations between marginalized racial and ethnic identities with the endorsement of PLEs partially reflects the sequelae of systemic socio-environmental factors. Findings suggest the potential for intervening upon environmental risk factors to target the reduction of cumulative stress over time, which may in turn buffer against the development of PLEs. Using longitudinal data from 11,876 young adolescents aged 9-10 from the Adolescent Brain Cognitive Development (ABCD) study, this study examined environmental (e.g., poverty) and stress-related factors (e.g., experiences of discrimination, childhood adversity) that are associated with psychotic-like experiences, and whether these factors explain racial/ethnic differences in psychotic-like experiences. The authors found evidence that the association between these environmental risk factors and psychotic-like experiences is partially explained by cumulative stress, and that differences in psychotic-like experiences across racial/ethnic groups were accounted for by both environmental risk factors and stress. Results highlight that systemic factors may explain higher levels of psychotic-like experiences among historically marginalized racial/ethnic groups. Findings suggest the potential for intervening upon modifiable risk factors to buffer against stress, and in turn, the development of psychotic-like experiences over time. We worked to ensure sex and gender balance in the recruitment of human participants.

Trochlea Dysplasia as the Major Anatomic Risk Factors for Patellofemoral Joint Instability: An Infographic as a Visual Learning Tool.

Patellofemoral instability (PFI) is a common condition in children and adolescents, ranging from mild discomfort and mal-tracking to lateral patellar dislocation [1]. A number of anatomical risk factors have been described in the literature, such as trochlear dysplasia, patella alta, excessive tibial tuberosity to trochlear groove (TT-TG) distance, patellar tilt and soft tissue alterations [2]. Among them, TD has been identified as the main anatomical risk factor with the strongest association with PFI [1, 2]. In the study by Dejour et al. [2] radiographically observed TD was identified in 96% of patients with a history of patellofemoral dislocation [1, 2]. Patients with Dejour Type D dysplasia are characterized by a prominent and convex lateral facet with a vertical connection to a hypoplastic medial facet (Figure 1), which provides inadequate tracking of the patella in the trochlea during flexion leading to patella subluxation [2]. Non-operative treatment of lateral patellar dislocation presents a rate of re-dislocation up to 70% within 24 months of the first episode [3]. Sulcus deepening trochleoplasty is indicated for Type B and D dysplasia, in order to improve patella tracking, reduce the rate of re-dislocation and achieve good functional outcomes [2, 4]. Trochlea dysplasia is defined as a shallow or flattened groove with decreased resistance to lateral patellar translation. TD can be assessed on computed tomography (CT) and magnetic resonance imaging (MRI) with the use of overlapping axial images and are able to show perfectly the global shape of the femoral trochlea [2]. The thresholds for identifying trochlear dysplasia are established based on the sulcus angle ≥ 145°, medial/lateral trochlea facet asymmetry < 40%, trochlear depth < 3 mm and lateral trochlear inclination ≤ 11° and therefore it can be used in young adolescents [4, 5]. A deep knowledge of anatomic variations and abnormalities of the patellofemoral joint, which may predispose to PFI, is crucial in order to choose the appropriate treatment for each patient.

Fibrolamellar carcinoma registry: Opportunities and challenges.

e16384 Background: Fibrolamellar carcinoma (FLC) is a rare form of primary liver cancer which affects young adults and adolescents without underlying liver disease or cirrhosis. The tumors are typically well circumscribed masses characterized pathologically by well differentiated polygonal hepatic cells with eosinophilic and granular cytoplasm surrounded by fibrous bands. DNAJB1 and PRKACA fusion is perceived as a dominant recurrent genetic alteration in FLC. FLC affects patients worldwide and a continued lack of an international database remains a knowledge gap. Further, there remains a poor understanding of FLC etiology, and major unmet need for more effective therapy. Methods: A patient-centered multi time-points, dynamic registry was developed by Memorial Sloan Kettering (MSK) in collaboration with Google and Maven Wave. The effort was supported by the Fibrolamellar Cancer Foundation (FCF). The study was opened worldwide except for the European Union pending the acquisition of the requiredGeneral Data Protection Regulation (GDPR) of data control and processing. The latter were assigned to Trinity College Dublin (TCD); a partner in this study. Participants were required to have a Google account to access the study. Demographic, clinical and response data were collected at baseline and at selected time points (monthly for up to 18 months). The aim of the registry was to provide a longitudinal understanding of the biography and natural history of the disease and outcomes. Results: Between May 2021 and December 2023, the study was broadcasted publicly worldwide through different venues including MSK, FCF, websites and Google engine. Only 14 patients responded. Table 1 summarizes the study sequence and patients’ enrollment. On average, the participants completed 41% of the monthly surveys. Four responders out of 5 patients were female, with a median age of 32 years (range 21-53). Conclusions: The registry provided a unique opportunity to access a broad global community of patients with FLC. Poor participation was key main limiting factor. Barriers include: (1) the presence of competing registries or studies for FLC, (2) technical limitations such as the exclusivity to access the registry to Google account. Follow-up emails may have been received in spam or junk folders, (3) complexities posed by the GDPR in Europe, and (4) patient-related factors including preoccupation with treatments and symptom management of their illness add to the disinterest in or inability to fill the monthly surveys. Unifying efforts and collaborations among caring physicians and scientists, medical centers, foundations, and patient advocacy groups across the world can help overcome the current challenges and accelerate the buildup of resources for research and practice improvement for the rare FLC.

Revisiting the Imaging Characteristics of Chondroblastoma with Special Emphasis on Prognosis and Radiological Predictors of Local Tumor Recurrence

Background Chondroblastoma is an uncommon benign cartilaginous tumor of young adults and adolescents, accounting for 1% of all bone tumors. We aim to analyze the imaging characteristics of pathologically proven chondroblastoma, measure the incidence rate of local recurrence of this tumor, and identify factors that may influence its local recurrence. Materials and methods The details of a total of 44 patients with pathologically proven chondroblastoma who underwent surgery and followed up by cross-sectional imaging between January 2006 and March 2021 at the KFSHRC in Riyadh were retrieved from our archive. All available modalities, including plain radiography, CT, and magnetic resonance imaging (MRI), performed at baseline and on follow-up were reviewed and correlated with the histopathological diagnosis. Recurrence was calculated from the date of surgery to the date of recurrence or the date of being lost to follow-up depending on the date of recurrence. The statistical software STATA was used to analyze the data. Results The tumor recurrence rate was 4.55% (n = 2). Similarly, the residual tumor rate was 4.55% (n = 2). No metastases were documented. The recurrence-free survival was 93.8% at the 722-day follow-up. More than 95% of lesions demonstrated typical imaging features including: a well-defined lobulated margin, intermediate-to-low signal on T2-weighted images, and perilesional edema. Conclusions This study emphasizes the imaging findings of chondroblastoma, which classically affects skeletally immature patients. Although imaging findings cannot be used to predict recurrence or survival, we obtained excellent prognosis following surgical treatment at our institution.

Neural Tracking of Perceived Parent, but Not Peer, Norms Is Associated with Longitudinal Changes in Adolescent Attitudes about Externalizing Behaviors.

Adolescents' perceptions of parent and peer norms about externalizing behaviors influence the extent to which they adopt similar attitudes, yet little is known about how the trajectories of perceived parent and peer norms are related to trajectories of personal attitudes across adolescence. Neural development of midline regions implicated in self-other processing may underlie developmental changes in parent and peer influence. Here, we examined whether neural processing of perceived parent and peer norms in midline regions during self-evaluations would be associated with trajectories of personal attitudes about externalizing behaviors. Trajectories of adolescents' perceived parent and peer norms were examined longitudinally with functional neuroimaging (n = 165; ages 11-16 years across three waves; 86 girls, 79 boys; 29.7% White, 21.8% Black, 35.8% Latinx, 12.7% other/multiracial). Behavioral results showed perceived parent norms were less permissive than adolescents' own attitudes about externalizing behaviors, whereas perceived peer norms were more permissive than adolescents' own attitudes, effects that increased from early to middle adolescence. Although younger adolescents reported less permissive attitudes when they spontaneously tracked perceived parent norms in the ventromedial and medial pFCs during self-evaluations, this effect weakened as they aged. No brain-behavior effects were found when tracking perceived peer norms. These findings elucidate how perceived parent and peer norms change in parallel with personal attitudes about externalizing behaviors from early to middle adolescence and underscore the importance of spontaneous neural tracking of perceived parent norms during self-evaluations for buffering permissive personal attitudes, particularly in early adolescence.

Parenting Practices Are Associated With Out-of-School Physical Activity in US Adolescents in 2014.

Lack of physical activity (PA) is associated with obesity, diabetes, hypertension, cardiovascular diseases, and cancer. Parenting practices influence PA in young children. However, there is little evidence available for adolescents. We examined whether parenting practices were associated with out-of-school PA (OSPA) in US adolescents. This cross-sectional 2019 study analyzed data from the 2014 FLASHE study, a web-based, quota-sampled survey of parent-adolescent dyads. Inclusion required survey completion and parents to live with their teen (ages 12-17y old). Physically limited adolescents were excluded. Dyads were stratified by teen age. Exposures included parental modeling, monitoring, facilitation, restriction, guided choice, and pressure. The outcomes of interest were OSPA Youth Activity Profile scores. Odds ratios (ORs) with 95% confidence intervals (CI) were calculated using adjusted logistic regressions. A total of 1109 dyads were included. Guided choice increased odds of OSPA for 15- to 17-year-olds (OR = 2.12; 95% CI, 1.17-3.84). Facilitation increased odds of OSPA for 12- to 14-year-olds (OR = 2.21; 95% CI, 1.13-4.33). Monitoring decreased odds of OSPA for 15- to 17-year-olds (OR = 0.34; 95% CI, 0.20-0.57) and 12- to 14-year-olds (OR = 0.45; 95% CI, 0.27-0.74). Friend support increased odds of OSPA in 15- to 17-year-olds (OR = 4.03; 95% CI, 2.29-7.08) and 12- to 14-year-olds (OR = 3.05; 95% CI 1.69-5.51). Future interventions should prioritize (1)shared decision making for older teens, (2)access to PA opportunities for younger adolescents, and (3)promoting peer PA and friend support for everyone.

Validation of Arabic versions of the child psychosocial distress screener and pediatric symptom checklist for young adolescents living in vulnerable communities in Lebanon

BackgroundIn humanitarian settings, brief screening instruments for child psychological distress have potential to assist in assessing prevalence, monitoring outcomes, and identifying children and adolescents in most need of scarce resources, given few mental health professionals for diagnostic services. Yet, there are few validated screening tools available, particularly in Arabic.MethodsWe translated and adapted the Child Psychosocial Distress Screener (CPDS) and the Pediatric Symptom Checklist (PSC) and conducted a validation study with 85 adolescents (aged 10–15) in Lebanon. We assessed internal consistency; test-retest reliability; convergent validity between adolescent- and caregiver-report and between the two measures; ability to distinguish between clinical and non-clinical samples; and concurrent validity against psychiatrist interview using the Kiddie Schedule for Affective Disorders and Schizophrenia.ResultsThe translated and adapted child-reported PSC-17 and PSC-35, and caregiver-reported PSC-35 all showed adequate internal consistency and test-retest reliability and high concurrent validity with psychiatrist interview and were able to distinguish between clinical and non-clinical samples. However, the caregiver-reported PSC-17 did not demonstrate adequate performance in this setting. Child-reported versions of the PSC outperformed caregiver-reported versions and the 35-item PSC scales showed stronger performance than 17-item scales. The CPDS showed adequate convergent validity with the PSC, ability to distinguish between clinical and non-clinical samples, and concurrent validity with psychiatrist interview. Internal consistency was low for the CPDS, likely due to the nature of the brief risk-screening tool. There were discrepancies between caregiver and child-reports, worthy of future investigation. For indication of any diagnosis requiring treatment, we recommend cut-offs of 5 for CPDS, 12 for child-reported PSC-17, 21 for child-reported PSC-35, and 26 for caregiver-reported PSC-35.ConclusionsThe Arabic PSC and CPDS are reliable and valid instruments for use as primary screening tools in Lebanon. Further research is needed to understand discrepancies between adolescent and caregiver reports, and optimal methods of using multiple informants.

Tuberculosis Immunoreactivity Surveillance in Malawi (Timasamala)-A protocol for a cross-sectional Mycobacterium tuberculosis immunoreactivity survey in Blantyre, Malawi.

Tuberculosis (TB) transmission and prevalence are dynamic over time, and heterogeneous within populations. Public health programmes therefore require up-to-date, accurate epidemiological data to appropriately allocate resources, target interventions, and track progress towards End TB goals. Current methods of TB surveillance often rely on case notifications, which are biased by access to healthcare, and TB disease prevalence surveys, which are highly resource-intensive, requiring many tens of thousands of people to be tested to identify high-risk groups or capture trends. Surveys of "latent TB infection", or immunoreactivity to Mycobacterium tuberculosis (Mtb), using tests such as interferon-gamma release assays (IGRAs) could provide a way to identify TB transmission hotspots, supplementing information from disease notifications, and with greater spatial and temporal resolution than is possible to achieve in disease prevalence surveys. This cross-sectional survey will investigate the prevalence of Mtb immunoreactivity amongst young children, adolescents and adults in Blantyre, Malawi, a high HIV-prevalence city in southern Africa. Through this study we will estimate the annual risk of TB infection (ARTI) in Blantyre and explore individual- and area-level risk factors for infection, as well as investigating geospatial heterogeneity of Mtb infection (and its determinants), and comparing these to the distribution of TB disease case-notifications. We will also evaluate novel diagnostics for Mtb infection (QIAreach QFT) and sampling methodologies (convenience sampling in healthcare settings and community sampling based on satellite imagery), which may increase the feasibility of measuring Mtb infection at large scale. The overall aim is to provide high-resolution epidemiological data and provide new insights into methodologies which may be used by TB programmes globally.

Diverging trends in alcohol use and mental health in Australian adolescents: A cross-cohort comparison of trends in co-occurrence.

In recent years, psychological distress in Western countries has rapidly increased among older adolescents while alcohol use has declined, though little is known about younger adolescents. It is also unclear if and how these trends relate to co-occurring alcohol use and distress. This study sought to examine temporal changes in the prevalence of distress, alcohol use, and their co-occurrence among young Australians. This study used data from 13,388 youth in their early teens (aged 12-14). Differences in the prevalence of high psychological distress (Kessler-6≥13), any alcohol use (standard drink in past 3/6months), and their co-occurrence across cohorts (2007, 2012, 2014, 2019) were tested through log-binomial regression models. Changes in co-occurrence across cohorts were tested with cohort-by-alcohol interactions predicting distress, and vice-versa. Differential trends by sex were evaluated. From 2007 to 2019, the prevalence of high distress more than doubled (4.6%-13.5%) while alcohol use decreased by ∼90% (11.8%-3.1%). Distress increased more-so among females, while alcohol use decreased more-so among males. The prevalence of high distress was significantly greater among adolescents who used alcohol compared to those who had not (>2 times higher), with this co-occurrence remaining consistent across cohorts. Psychological distress appears to be increasing similarly among youth in their early teens who do and do not use alcohol. At the same time, alcohol use is decreasing similarly among youth with and without distress. While alcohol use does not appear to be a driver of increases in distress, rates of co-occurring alcohol use and distress remain high. Addressing co-occurrence and distress-specific mechanisms remain necessary.

Impact of a mindfulness-based intervention on neurobehavioral functioning and its association with large-scale brain networks in preterm young adolescents.

Adolescents born very preterm (VPT; <32 weeks of gestation) face an elevated risk of executive, behavioral, and socioemotional difficulties. Evidence suggests beneficial effects of mindfulness-based intervention (MBI) on these abilities. This study seeks to investigate the association between the effects of MBI on executive, behavioral, and socioemotional functioning and reliable changes in large-scale brain networks dynamics during rest in VPT young adolescents who completed an 8-week MBI program. Neurobehavioral assessments and resting-state functional magnetic resonance imaging were performed before and after MBI in 32 VPT young adolescents. Neurobehavioral abilities in VPT participants were compared with full-term controls. In the VPT group, dynamic functional connectivity was extracted by using the innovation-driven coactivation patterns framework. The reliable change index was used to quantify change after MBI. A multivariate data-driven approach was used to explore associations between MBI-related changes on neurobehavioral measures and temporal brain dynamics. Compared with term-born controls, VPT adolescents showed reduced executive and socioemotional functioning before MBI. After MBI, a significant improvement was observed for all measures that were previously reduced in the VPT group. The increase in executive functioning, only, was associated with reliable changes in the duration of activation of large-scale brain networks, including frontolimbic, amygdala-hippocampus, dorsolateral prefrontal, and visual networks. The improvement in executive functioning after an MBI was associated with reliable changes in large-scale brain network dynamics during rest. These changes encompassed frontolimbic, amygdala-hippocampus, dorsolateral prefrontal, and visual networks that are related to different executive processes including self-regulation, attentional control, and attentional awareness of relevant sensory stimuli.

The Prevalence of Caregiving among Young People.

With the increasing number of people with chronic diseases and disabilities, the number of family members as caregivers have also been growing. Despite the attention paid to caregiving in recent years, little is known about caregiving among young people, particularly its global prevalence. The lack of information has important implications for health policy and management, resulting in the inability to form appropriate evidence-based policies and managerial decision making. This study aims to derive an estimate of the prevalence of caregiving among young people through a systematic review of the current literature. The results of this study revealed a prevalence of caregiving among younger adolescents of between 1.1% (1.06-1.14%) and 12.0% (11.02-12.98%). However, the assessment of caregiving varies across studies, and all were conducted in developed countries. These results provide information on the burden of caregiving in young people and reveal the lack of global information, calling for more research on and attention to this specific population.

Mixing energy drinks and alcohol during adolescence impairs brain function: A study of rat hippocampal plasticity

In the last decades, the consumption of energy drinks has risen dramatically, especially among young people, adolescents and athletes, driven by the constant search for ergogenic effects, such as the increase in physical and cognitive performance. In parallel, mixed consumption of energy drinks and ethanol, under a binge drinking modality, under a binge drinking modality, has similarly grown among adolescents. However, little is known whether the combined consumption of these drinks, during adolescence, may have long-term effects on central function, raising the question of the risks of this habit on brain maturation. Our study was designed to evaluate, by behavioral, electrophysiological and molecular approaches, the long-term effects on hippocampal plasticity of ethanol (EtOH), energy drinks (EDs), or alcohol mixed with energy drinks (AMED) in a rat model of binge-like drinking adolescent administration. The results show that AMED binge-like administration produces adaptive hippocampal changes at the molecular level, associated with electrophysiological and behavioral alterations, which develop during the adolescence and are still detectable in adult animals. Overall, the study indicates that binge-like drinking AMED adolescent exposure represents a habit that may affect permanently hippocampal plasticity.

Efficacy and safety of transcranial pulse stimulation in young adolescents with attention-deficit/hyperactivity disorder: a pilot, randomized, double-blind, sham-controlled trial.

This is the first study to evaluate the efficacy and safety of transcranial pulse stimulation (TPS) for the treatment of attention-deficit/hyperactivity disorder (ADHD) among young adolescents in Hong Kong. This double-blind, randomized, sham-controlled trial included a TPS group and a sham TPS group, encompassing a total of 30 subjects aged 12-17 years who were diagnosed with ADHD. Baseline measurements SNAP-IV, ADHD RS-IV, CGI and executive functions (Stroop tests, Digit Span) and post-TPS evaluation were collected. Both groups were assessed at baseline, immediately after intervention, and at 1-month and 3-month follow-ups. Repeated-measures ANOVAs were used to analyze data. The TPS group exhibited a 30% reduction in the mean SNAP-IV score at postintervention that was maintained at 1- and 3-month follow-ups. TPS is an effective and safe adjunct treatment for the clinical management of ADHD. ClinicalTrials.Gov, identifier NCT05422274.

BCG activation of trained immunity is associated with induction of cross reactive COVID-19 antibodies in a BCG vaccinated population.

Pakistan is endemic to a diverse set of parasitic, mycobacterial and viral diseases. The recognition of BCG Trained Immunity (TI) led us to postulate that the continued presence of BCG-TI may play a protective role, previously reported for both infectious and noninfectious conditions. Most of the previous studies have addressed the issue of BCG-TI in the paediatric populations. This study addressed the key issue of maintenance of BCG-TI in a wider age range (adolescent and adults) to identify the strength and quality of the immune responses. To assess the BCG-induced recall responses in healthy individuals by cytokines secreted from the TI network and its potential role in providing cross-protection against COVID-19 and other viral infections. In this cross-sectional study, healthy young adults and adolescents (n = 20) were recruited from 16-40 years of age, with no prior history of TB treatment, autoimmune, or chronic inflammatory condition. BCG-induced cytokine responses were assessed using prototypic markers for cells of the TI network [macrophages [M1 (TNFα, IFNγ), M2 (IL10)], NK (IL2), Gamma delta (γδ) T (IL17, IL4)] and SARS CoV2 IgG antibodies against RBD using short-term (12 hrs.) cultures assay. Significant differences were observed in the magnitude of recall responses to BCG with macrophage cytokines showing the highest mean levels of TNFα (9148 pg/ml) followed by IL10 (488 pg/ml) and IFNγ (355 pg/ml). The ratio of unstimulated vs.BCG-stimulated cytokines was 132 fold higher for TNFα, 40 fold fo r IL10, and 27 fold for IFNγ. Furthermore, SARS-CoV-2 antibodies were also detected in unstimulated plasma which showed cross reactivity with BCG. The presence of cross reactive antibodies to SARS-CoV-2 and the relative ratio of pro- and anti-inflammatory cytokines secreted by activated TI cellular network may play a pivotal role in protection in the early stages of infection as observed during the COVID-19 pandemic in the younger age groups resulting in lower morbidity and mortality.

The relationship between attitude toward physical activity and weight gain in children and young adolescence.

The purpose of this study was to investigate the association between attitudes toward physical activity and weight gain among children and young adolescents with an additional focus on the impact of gender on these attitudes. Employing a descriptive survey method, data were systematically gathered via purposive sampling from 11 specific cities in Türkiye, ensuring representation from all seven regions. A total of 3,138 students, aged between 9 and 14 years, participated in this study, with a distribution of 46% girls and 54% boys. To assess the attitudes of children and young adolescents toward physical activity, the Youth Physical Activity Attitude Scale was utilized. Height and body weight measurements were taken to determine the body mass index of participants. SPSS 26.0 software facilitated the statistical analyses, including Pearson correlation analysis to explore relationships between variables. Multivariate Analysis of Variance was employed to evaluate the impact of age, BMI, and gender on attitudes toward physical activity. Participants classified as normal weight exhibited a more positive attitude towards physical activity compared to their obese and overweight counterparts. Moreover, a significant gender difference emerged, with boys demonstrating significantly higher positive attitudes toward physical activity than girls. However, no significant difference was observed in negative attitudes based on gender. The study also revealed that an escalation in negative attitudes towards physical activity correlated with students being categorized as underweight, overweight, or obese, as opposed to having a normal weight status. Additionally, a statistically significant divergence in both positive and negative attitudes towards physical activity was found based on age. Specifically, the results indicated that students aged 9 and 14 exhibited lower levels of positive attitude when contrasted with their counterparts of different age groups. Conversely, in the domain of negative attitudes, students at the age of 9 scored higher than their peers in other age categories. Attitudes towards physical activity can serve as a convenient indicator and guide for assessing the effectiveness of various practices or interventions aimed at promoting physical activity, with recognition of the significant gender difference in positive attitudes among children and young adolescents.
