Dietary exposure to polyaromatic hydrocarbons of the Hong Kong population

Polyaromatic hydrocarbons (PAHs) are ubiquitous in the environment and food. The Joint FAO/WHO Expert Committee on Food Additives concluded 13 individual PAHs are carcinogenic and genotoxic in vitro and in vivo. Food is recognized as the main source of exposure to PAHs for adult non-smokers, which contributed to more than 90% of total exposure. In this study, 300 food samples were collected in Hong Kong, analysed the levels of 16 European Union priority PAHs, the dietary exposure to these PAHs by the local adult population from these food items, and the associated health risk. The most predominant detectable PAH was chrysene (CHR) (14.4%), followed by benzo[c]fluorene (11.2%), benzo[a]anthracene (BaA) (10.6%) and benzo[b]fluoranthene (BbFA) (7.8%). The dietary exposures for average consumers of benzo[a]pyrene (BaP) and PAH4 (sum of BaP, CHR, BaA and BbFA) were 0.13–0.90 and 1.4–4.2 ng/kg bw/day respectively for lower and upper bound approaches. Cereal and its products contributed more than 50% to BaP and PAH4 for average consumers in a lower-bound approach. The margin of exposure (MOE) approach was used to assess the health risks of consumers. The calculated MOE values for both BaP and PAH4 of the average and high consumers (90th percentile) were >50,000, indicating a low concern for the health of the Hong Kong population.

How much does overnutrition weigh? The environmental and social impacts of Metabolic Food Waste in Italy

Excess Food Energy Intake (EFEI), namely Metabolic Food Waste (MFW) corresponds to excess calorie intake related to overconsumption of food and is responsible for overweight (OW) and obesity (OB) conditions. Identifying its causes and impacts could be important, so that it can be prevented and reduced, generating health, environmental and societal benefits. Therefore, this research quantifies MFW among OW and OB adult populations (18–75 years) in Italy and its environmental and social implications. Life cycle assessment (LCA) through the Simapro 9.5 software was used and then, the results were monetized according to the Environmental Price Handbook to understand the real environmental cost. Finally, Social LCA (S-LCA) was considered following the Product Social Impact Assessment (PSILCA) guidelines to understand the potential social risks behind the food that ends up on our plates. The results highlight the amount of MFW in Italy is 2696 billion kcal/year corresponding to 1.59 Mtons over-consumed food/year, while the impacts are mainly related to global warming (8.78 Mtons CO2 eq/year, or 2.29 % of the total Italian CO2 emissions), terrestrial ecotoxicity (843,451 tons 1.4-DCB/year), freshwater ecotoxicity (222,483 tons 1.4 DCB eq/year), and land consumption (8 million m2a eq/year), mostly due to the meat, fats and oils and sweets overconsumption. Impacts monetization also shows that MFW could induce an environmental price of € 1340/per capita/year, and finally, the S-LCA reveals how overconsumption of food has the potential to affect gender discrimination, water depletion, trade union, and social discrimination due to the high proportion of labor migrants in the agricultural sector.

Urinary polycyclic aromatic hydrocarbons and adult obesity among the US population: NHANES 2003-2016.

Polycyclic aromatic hydrocarbons (PAHs) are naturally occurring environmental pollutants that may contribute to obesity in the adult population. To investigate the relationship between the urinary concentrations of PAH metabolites and adult obesity among the US population, the National Health and Nutritional Examination Survey (NHANES, 2003-2016) was used as a data source for this study. As many as 4464 participants in the NHANES 2003-2016 were included in the final analyses. We used logistic regression to look at the link between urinary PAH metabolites and obesity, using odds ratios (ORs) and 95% confidence intervals (CIs). The study sample comprised 4464 individuals aged ≥18 years, 2199 were male and 2265 were female. The study characteristics for four different quartiles were analyzed, and the average ages of the four urinary PAH quartiles were 49.61 ± 20.01, 46.63 ± 20.33, 44.28 ± 19.19, and 43.27 ± 17.68 years, respectively. In the quartile analysis of all participants, the third quartile was significantly associated with an increased prevalence of obesity (OR = 1.33, 95% CI = 1.12-1.59) with p-values <.05. In addition, females, but not males, had a strong link between the second, third, and fourth quartiles of urinary PAH and a higher risk of obesity (OR = 1.27, 95% CI = 1.00-1.61; OR = 1.52, 95% CI = 1.19-1.94; and OR = 1.39, 95% CI = 1.09-1.78). In conclusion, the study observed that urinary PAH metabolites were associated with the prevalence of obesity among the US population.

Headache/migraine-related stigma, quality of life, disability, and most bothersome symptom in adults with current versus previous high-frequency headache/migraine and medication overuse: results of the Migraine Report Card survey

BackgroundHigh-frequency headache/migraine (HFM) and overuse of acute medication (medication overuse [MO]) are associated with increased disability and impact. Experiencing both HFM and MO can potentially compound impacts, including stigma; however, evidence of this is limited. The objective of this report was to evaluate self-reported stigma, health-related quality of life (HRQoL), disability, and migraine symptomology in US adults with HFM + MO from the Harris Poll Migraine Report Card survey.MethodsUS adults (≥ 18 yrs., no upper age limit) who screened positive for migraine per the ID Migraine™ screener completed an online survey. Participants were classified into “current HFM + MO” (≥ 8 days/month with headache/migraine and ≥ 10 days/month of acute medication use over last few months) or “previous HFM + MO” (previously experienced HFM + MO, headaches now occur ≤ 7 days/month with ≤ 9 days/month of acute medication use). Stigma, HRQoL, disability, and most bothersome symptom (MBS) were captured. The validated 8-item Stigma Scale for Chronic Illnesses (SSCI-8) assessed internal and external stigma (scores ≥ 60 are clinically significant). Raw data were weighted to the US adult population. Statistically significant differences were determined by a standard t-test of column proportions and means at the 90% (p < 0.1) and 95% (p < 0.05) confidence levels.ResultsParticipants (N = 550) were categorized as having current (n = 440; mean age 41.1 years; 54% female; 57% White, not Hispanic; 24% Hispanic; 11% Black, not Hispanic) or previous (n = 110; mean age 47.2 years; 49% female; 75% White, not Hispanic; 13% Hispanic; 4% Black, not Hispanic) HFM + MO. Compared to those with previous HFM + MO (21%), adults with current HFM + MO were more likely to experience clinically significant levels of stigma (47%). Men with current HFM + MO (52% compared to men with previous HFM + MO [25%] and women with current [41%] or previous [18%] HFM + MO), non-Hispanic Black (51% compared to White, not Hispanic [45%] and Hispanic [48%] current HFM + MO groups and White, not Hispanic previous HFM + MO [12%]), current HFM + MO aged 18–49 years (50% compared to those with current HFM + MO aged ≥ 50 years [33%] and those with previous HFM + MO aged 18–49 [34%] and ≥ 50 years [4%]), and employed respondents (53% current and 29% previous compared to those not employed [32% current and 12% previous]) reported higher rates of clinically significant stigma. Those with current HFM + MO were more likely to have worse HRQoL and disability due to headache/migraine. Respondents aged ≥ 50 years with current HFM + MO were more likely than respondents aged 18–49 years with current HFM + MO to indicate that their overall quality of life (66% vs. 52%) and their ability to participate in hobbies/activities they enjoy were negatively impacted by headache/migraine (61% vs. 49%). Pain-related symptoms were identified as the MBS.ConclusionsTogether these data suggest that current and previous HFM + MO can be associated with undesirable outcomes, including stigma and reduced HRQoL, which were greatest among people with current HFM + MO, but still considerable for people with previous HFM + MO.Graphical abstract

Accessory thoracic muscles in human fetuses.

Typically, the anterior thoracic wall musculature is composed of the pectoralis major and pectoralis minor. Embryologically, these two muscles are originated from a common pectoral muscle mass; therefore, disruption of the normal development and differentiation could give rise to an aberrant or accessory muscle. The main aim of this study is to demonstrate and classify the accessory muscles of the pectoralis region in human fetuses. Fifty spontaneously aborted human fetuses (25 male and 25 female, 100 sides) aged 18-38 weeks of gestation at death, and fixed in 10% formalin solution were examined. Following parental approval, the fetuses were donated to the Medical University anatomy program. The pectoralis major and minor muscle's morphology, the possible occurrence of accessory muscles of pectoral region and its morphology, their origins, and insertions, as well as the morphometric details, were assessed. The pectoralis major and minor were bilaterally found in all fetuses (100 cases). The accessory muscles of pectoral region were found in 16 cases (16%), and four types were differentiated. The Pectoralis Quartus muscle was the most common type of accessory muscles found in this study and occurred in 8 cases. The axillary arch muscle was observed in 3 cases. The chondrocoracoideus muscle was observed in 3 cases. The sternalis muscle occurred in 2 cases, and one of them was bifurcated. The thoracic region is characterized by a large amount of morphological variations, which are observed not only in adult population, but also among human fetuses. The pectoralis quartus was the most frequent variation in this study. Accessory structures like sternalis muscle, chondrocoracoideus muscle, pectoralis quartus muscle, or axillary arch muscle may have clinical implications, and knowledge about them is very useful for clinicians, especially plastic surgeons, thoracic surgeons, and orthopedics.

Clinicopathologic Features and Outcomes of Acute Leukemia Harboring PICALM::MLLT10 Fusion

The PICALM::MLLT10 fusion is a rare but recurrent cytogenetic abnormality in acute leukemia, with limited clinicopathologic and outcome data available. Herein, we analyzed 156 acute leukemia patients with PICALM::MLLT10 fusion, including 12 patients from our institutions and 144 patients from the literature. The PICALM::MLLT10 fusion preferentially manifested in pediatric and young adult patients, with a median age of 24 years. T-lymphoblastic leukemia/lymphoma (T-ALL) constituted 65% of cases, acute myeloid leukemia (AML) 27%, and acute leukemia of ambiguous lineage (ALAL) 8%. About half of T-ALL were classified as an early T-precursor (ETP)-ALL. In our institutions’ cohort, mediastinum was the most common extramedullary site of involvement. Eight of 12 patients were diagnosed with T-ALL exhibiting a pro-/pre-T stage phenotype (CD4/CD8-double negative, CD7-positive), and frequent CD79a expression. NGS revealed pathogenic mutations in 5 of 6 tested cases, including NOTCH1, and genes in RAS and JAK-STAT pathways and epigenetic modifiers. Of 138 cases with follow-up, pediatric patients (<18 years) had 5-year overall survival (OS) of 71%, significantly better than adults at 33%. The 5-year OS for AML patients was 25%, notably shorter than T-ALL patients at 54%; this distinction was observed in both pediatric and adult populations. Furthermore, adult but not pediatric ETP-ALL patients demonstrated inferior survival compared to non-ETP-ALL patients. Neither karyotype complexity nor transplant status had a discernible impact on OS. In conclusion, PICALM::MLLT10 fusion is most commonly seen in T-ALL patients, particularly those with an ETP phenotype. AML and adult ETP-ALL patients had adverse prognosis. PICALM::MLTT10 fusion testing should be considered in T-ALL, AML, and ALAL patients.

Correcting mortality estimates among children and youth on antiretroviral therapy in southern Africa: A comparative analysis between a multi-country tracing study and linkage to a health information exchange.

The objective of this study is to assess the outcomes of children, adolescents and young adults with HIV reported as lost to follow-up, correct mortality estimates for children, adolescents and young adults with HIV for unascertained outcomes in those loss to follow-up (LTFU) based on tracing and linkage data separately using data from the International epidemiology Databases to Evaluate AIDS in Southern Africa. We included data from two different populations of children, adolescents and young adults with HIV; (1) clinical data from children, adolescents and young adults with HIV aged ≤24 years from Lesotho, Malawi, Mozambique, Zambia and Zimbabwe; (2) clinical data from children, adolescents and young adults with HIV aged ≤14 years from the Western Cape (WC) in South Africa. Outcomes of patients lost to follow-up were available from (1) a tracing study and (2) linkage to a health information exchange. For both populations, we compared six methods for correcting mortality estimates for all children, adolescents and young adults with HIV. We found substantial variations of mortality estimates among children, adolescents and young adults with HIV reported as lost to follow-up versus those retained in care. Ascertained mortality was higher among lost and traceable children, adolescents and young adults with HIV and lower among lost and linkable than those retained in care (mortality: 13.4% [traced] vs. 12.6% [retained-other Southern Africa countries]; 3.4% [linked] vs. 9.4% [retained-WC]). A high proportion of lost to follow-up children, adolescents and young adults with HIV had self-transferred (21.0% and 47.0%) in the traced and linked samples, respectively. The uncorrected method of non-informative censoring yielded the lowest mortality estimates among all methods for both tracing (6.0%) and linkage (4.0%) approaches at 2 years from ART start. Among corrected methods using ascertained data, multiple imputation, incorporating ascertained data (MI(asc.)) and inverse probability weighting with logistic weights were most robust for the tracing approach. In contrast, for the linkage approach, MI(asc.) was the most robust. Our findings emphasise that lost to follow-up is non-ignorable and both tracing and linkage improved outcome ascertainment: tracing identified substantial mortality in those reported as lost to follow-up, whereas linkage did not identify out-of-facility deaths, but showed that a large proportion of those reported as lost to follow-up were self-transfers.

Implementation and evaluation of a community-based mindful walking randomized controlled trial to sustain cognitive health in older African Americans at risk for dementia

BackgroundWith an increasing proportion of older adults and the associated risk of Alzheimer’s Disease and Related Dementias (ADRD) around the globe, there is an urgent need to engage in ADRD risk reduction efforts. African American (AA) older adults in the U.S. are disproportionally impacted by ADRD compared to other races and ethnicities. Mindful walking integrates two potentially protective factors of ADRD by elevating mindfulness and physical activity (i.e., walking), resulting in a synergistic behavioral strategy that is feasible and safe for older adults. However, the efficacy of applying this intervention for cognitive health outcomes has not been evaluated using experimental designs.MethodsThis paper documents the goal and protocol of a community-based, mindful walking randomized controlled trial to examine the short- and longer-term efficacy on cognitive and other health-related outcomes in ADRD at-risk AA older adults. The study outcomes include various brain health determinants, including cognitive function, quality of life, psychological well-being, physical activity, mindfulness, sleep, and overall health status. In addition, the estimated costs of program implementation are also collected throughout the study period. This study will recruit 114 older adults (ages 60+ years) with elevated ADRD risk from the Midlands region of South Carolina. Older adults are randomly assigned to participate in 24 sessions of outdoor mindful walking over three months or a delayed mindful walking group (n=57 in each group). Participants in both groups follow identical measurement protocols at baseline, after 12 weeks, after 18 weeks, and after 24 weeks from baseline. The outcome measures are administered in the lab and in everyday settings. Costs per participant are calculated using micro-costing methods. The eliciting participant costs for mindful walking engagement with expected results are reported using the payer and the societal perspectives.DiscussionThis study will generate evidence regarding the efficacy of mindful walking on sustaining cognitive health in vulnerable older adults. The results can inform future large-scale effectiveness trials to support our study findings. If successful, this mindful walking program can be scaled up as a low-cost and viable lifestyle strategy to promote healthy cognitive aging in diverse older adult populations, including those at greatest risk.Trial registrationClinicalTrials.gov number NCT06085196 (retrospectively registered on 10/08/2023).

Successful Aging Through Financial Empowerment (SAFE): Financial Coaching with Older Adult Victims of Financial Exploitation

ABSTRACT Financial exploitation (FE) of older adults is a growing public health problem. Current estimates of financial exploitation show between 5% and 11% of older adults are victimized each year. This study examined an empowerment-centered financial coaching intervention. Program records and participant baseline and follow-up assessment data were used to detail program dynamics and investigate participant outcomes. Most SAFE participants were very satisfied or satisfied (91%) with the services they received. Participants also reported significantly less stress at the six-month follow-up. These findings demonstrate that empowerment-centered financial coaching interventions can successfully address FE in older adult populations.

When Being Bad Feels Good: A Systematic Review of the Relationship Between Positive Emotion and Antisocial Behavior in Children and Adolescents.

Antisocial behavior in childhood and adolescence is associated with poor family and peer relationships, and a higher risk of mental and physical health problems in adulthood, as well as criminality. Emotions play a central role in children's moral development, but most research has focused on negative emotions (e.g., shame and guilt), in relation to childhood antisocial behavior. Research in adult populations indicates that positive emotions experienced in anticipation of, during, and after antisocial acts may play an important role in the development and maintenance of antisocial behavior. Consequently, this systematic review aimed to investigate the relationship between positive emotion and antisocial behavior in children and adolescents. A systematic search in five databases was conducted, yielding 52 studies that used different methodological approaches, samples, designs and methods to examine this association. Results provide support for a positive relationship between positive emotion and antisocial behavior across community, forensic and clinical samples. This link appeared to be stronger for younger children, boys, and for children high in social dominance, callous-unemotional or sensation-seeking traits. Results suggested that positive affect may act in concert with negative emotion, cognitive, personality and motivational processes, as well as peer influences to determine the initiation and maintenance of antisocial behavior. This review presents directions for future research and discusses the implications of findings for prevention and intervention programs for youth with antisocial behavior.

Study of the Efficacy of Sublingual Route Administration of Levothyroxine Na Tablets vs Oral Route in Cases with Refractory Primary Hypothyroidism

Abstract Background Hypothyroidism is a common disorder, with a prevalence of approximately 5% and incidence of approximately 250 /100,000 per year in the adult population both prevalence and incidence keep raising. Levothyroxine is the recommended hormone for replacement therapy in both overt and subclinical hypothyroidism. Aim of the Work Levothyroxine (L-T4) is the standard therapy of hypothyroidism. Our purpose was to compare the efficacy of the L-T4 sublingual tablet administration to standard oral L-T4 tablet in hypothyroid patients with refractory hypothyroidism. Subjects and Methods Our study was conducted on 40 patients who were documented to be refractory to oral thyroxine age range 18- 55, 38 females and 2males. Patients were recruited from Endocrinology and Metabolism clinic at Ain-Shams University and Internal medicine outpatient clinic at 6th of October University during the period from June 2019 to October 2020 Informed consent was obtained from all subjects. Results In our study showed a significant decrease in mean TSH (write the figures) on sublingually administrated levothyroxine tablets compared to orally administrated levothyroxine tablets and a significant rise of mean free T4 after 1 week. yet after 6 weeks there was insignificant difference of FT4 compared to oral levothyroxine. Patients who were antiparietal cell antibody positive demonstrated a non significant rise of free T4 level with almost doubling of level compared to oral levothyroxine at 1 week and 6 weeks interval, this was associated with a significant decline of serum TSH at 6 weeks interval. Also This was associated with a significant improvement in hypothyroidism symptoms Conclusion In conclusion, our study indicated that sublingual route for LT4 tablet administration was safe and innovative route for LT4 administration,it could improve compliance, overcome many obstacles with oral administration for intake with food,coffee,drug interaction and GI malabsorption.

The relationship between the dietary index based Meiji nutritional profiling system for adults and lifestyle-related diseases: a predictive validity study from the National Institute for Longevity Sciences-Longitudinal Study of Aging.

Nutritional profiling system (NPS) holds promise as a public health tool for companies to measure product healthiness and for individuals in making healthier food choices. The Meiji NPS for adults specifically targets lifestyle-related diseases prevalent among Japan's adult population, including overweight/obesity, hypertension, diabetes, and dyslipidemia. This study examined the cross-sectional association between the Meiji NPS for adults Dietary Index (MNfA-DI) and indicators of lifestyle-related diseases in a population. The study comprised 1,272 middle-aged individuals (40-64 years, 50.1% male) who participated in the seventh wave (2010-2012) of the National Institute for Longevity Sciences-Longitudinal Study of Aging project, with no missing data on three-day dietary records. The MNfA-DI was computed at the individual diet level (accounting for the whole diet) using arithmetic energy-weighted means. A higher MNfA-DI indicated a greater nutritional quality of an individual's overall diet. Lifestyle-related disease indicators included body mass index (BMI, kg/m2), body fat (%), systolic and diastolic blood pressure (mmHg), fasting plasma glucose (mg/dL), HbA1c (%), triglyceride levels (mg/dL), LDL, and HDL cholesterol levels (mg/dL). A multiple regression model was used to assess the association between the MNfA-DI and lifestyle-related disease indicators, adjusting for demographics, socioeconomic status, lifestyle factors, disease history, and energy intake as covariates, depending on the outcome. The median (interquartile range) age and MNfA-DI were 53.0 (46.0, 59.0) years and 10.1 (6.0, 14.0) points, respectively. MNfA-DI was negatively associated with body fat [partial regression coefficient (95% confidence interval) -0.04 (-0.07, -0.01)], diastolic blood pressure [-0.08 (-0.17, -0.002)], fasting plasma glucose [-0.18 (-0.33, -0.01)], and triglyceride [-1.36 (-2.16, -0.55)]. Additionally, MNfA-DI was also associated with almost indicators (except for LDL and HDL cholesterol) among participants with a BMI between 18.5 and 24.9 kg/m2. These findings suggest that the Meiji NPS for adults could be associated with a lower risk of lifestyle-related diseases. In addition, from a public health nutrition perspective, the Meiji NPS for adults may be useful to assess the food healthiness of the adult population.

P-008 Sperm DNA methylation landscape in infertile men with clinical varicocele before and after treatment

Abstract Study question As varicocele leads to poor semen parameters, does it also affect sperm DNA methylation levels? Does varicocele treatment help in epigenetics restoration in the sperm? Summary answer Varicocele leads to aberrant sperm DNA methylation and varicocele treatment helps in the partial restoration of sperm DNA methylation levels. What is known already Varicocele affects 15% to 20% of the adult male population and 20% of men with varicocele are reported to be infertile. Treatment modalities for varicocele improve semen parameters, yet more than 50% of cases remain infertile. High oxidative stress (OS) has been implicated as a key factor in varicocele-associated infertility. OS during spermatogenesis may lead to aberrant epigenetic modifications in spermatozoa. In view of the crucial role of sperm epigenome in its functionality, this study aims to evaluate sperm genome-wide DNA methylation by whole-genome bisulfite sequencing (WGBS) before and after varicocele treatment in men with varicocele. Study design, size, duration This is a case-control study, which includes (n = 28) healthy fertile men and (n = 35) infertile men with clinical varicocele. Study participants were recruited from ICMR-NIRRCH and, LTMG Hospital, Mumbai. According to the inclusion and exclusion criteria, study participants were recruited from December 2020 to November 2023. Varicocele patients were followed up, and semen samples (n = 18) were recollected after 3-6 months of varicocele treatment. Participants/materials, setting, methods WGBS was used to identify differentially methylated CpG (DMC) sites in sperm of varicocele group compared to controls. 5 samples from each group were pooled for WGBS. DMCs identified with ≥25% methylation change and ≤0.05 q-value. DMCs within genes relevant to sperm function were selected for validation in the study population by pyrosequencing. Differentially methylated Genes (DMGs) were identified based on the location of DMC and used for pathway analysis using KEGG and DAVID tools. Main results and the role of chance Varicocele group had significantly lower semen parameters compared to controls, which were found to be improved after varicocele treatment. WGBS of sperm DNA was done and DMC sites were obtained in varicocele group compared to controls. A total of 6414 DMCs were obtained, of which, 3730 were hypermethylated and 2684 were hypomethylated. Based on genomic context, differential methylation was observed in introns, exons, promoters and intergenic regions. WGBS analysis gave a total of 1484 DMGs. KEGG and DAVID pathway analysis revealed that the PI3K-Akt signaling, MAPK signaling, cAMP signaling, calcium signaling, signal transduction pathway, cell adhesion molecules, and tight junction, were affected in the varicocele group. The DMGs SPATA6L, H2AX, SOD2, BCL2, NF1, PRKN, CDKN1B, BCR, P2RX7, RNF212B obtained are involved in spermatogenesis, regulation of cell cycle, apoptotic signaling pathway, cell differentiation, regulation of ROS metabolic process, response to heat, mitochondria regulation, regulation of gene expression, etc. Pyrosequencing validation of a few selected DMCs reflects the same methylation difference (hypo or hyper) as obtained by the WGBS pooled sample. Significant hypermethylation and hypomethylation were observed in the H2AX DMC and CDKN1B DMC, respectively, in the varicocele population; however, after varicocele treatments, these methylation levels seem to be restored. Limitations, reasons for caution The limitations of this study are the small number of patients and pooled sperm DNA sample WGBS analysis in the study population. However, a pooling sample strategy is considered more efficient than a random sample selection strategy, as pooling minimizes the amount of information lost below the detection threshold. Wider implications of the findings This study identified differentially methylated genes relevant to spermatogenesis and sperm functions in the case of varicocele compared to fertile controls and gave deeper insights into the possibility of epigenetic restoration after varicocele treatment. This study provides insight into the molecular aetiology of varicocele associated infertility. Trial registration number Not Applicable

Evaluation of the nutritional quality of French children breakfasts according to the Breakfast Quality Score (BQS).

Breakfast meals provide essential nutrients and energy to children and adolescents. Based on recommendations from the International Breakfast Research Initiative (IBRI), the Breakfast Quality Score (BQS) was developed to assess breakfast nutritional value among the French adult population. However, its application to children remains unexplored. This study aimed to evaluate the BQS in assessing the nutritional quality of breakfasts consumed by French children aged 4-17 years. A total of 4,015 breakfasts, obtained from dietary recalls provided by 1,448 children participating in the French representative dietary survey (INCA3), were analyzed. As for adults, the performance of the BQS was tested through correlations with other nutritional indicators and comparison of nutrients and dietary components between tertiles of scores. The study examined the regularity of breakfast consumption and compared the BQS of children's breakfasts across socio-demographic modalities and breakfast categories distinguished by their primary grain component. Additionally, a predictive modeling using Partial Least Squares (PLS) regression identified influential INCA3 food groups. The majority of children consumed solid breakfasts regularly. Socio-professional category, household income and food insecurity influenced BQS, revealing contradictory disparities. Ready-to-eat cereal (RTEC) breakfasts had the highest BQS (73.5% for children and 73.1% for adolescent), while biscuits and viennoiseries scored the lowest (52% for children and 49.1% for adolescent). PLS highlighted RTECs, milk, and hot beverages (mainly containing chocolate milk) as being positively associated with BQS, while sweet beverages and viennoiseries were negatively associated. The study demonstrates the effectiveness of the BQS in assessing children's breakfast quality, with RTEC breakfasts showing the highest nutritional value. The findings provide insights into factors influencing breakfast nutritional quality and underscore the importance of promoting healthier breakfast choices among all children.

Fibro-Scan Based Score and Novel Noninvasive Serum Marker, FGF-21, to Assess Liver Fibrosis in Morbidly Obese Patients

Abstract Background (NAFLD) is currently the most common cause of liver disease in the Western world, affecting up to 20- 30% of the general adult population. It is a growing public health problem, because of the increasing prevalence of the pathologies that contribute to its development such as obesity and inflammation status. Aim of the Work The study is aimed to develop and validate noninvasive scoring system for assessment liver fibrosis in morbidly obese patients with NAFLD. Subjects and Methods This is a Prospective cohort study, was carried out on 50 morbidly obese patients selected from internal medicine department, El Demerdash Hospital, through a period of six months. Results There were 32(64.0%) male and 18(35.0%) female with mean age 40.48 (± 12.16) SD. There were 14(27.0%) between (20 -30), 11(22.0%) between (30-40), 9(18.0%) between (40-50) and 16(32.0%) ≥50. Mean Weight (Kg) was 106.6 (± 13.31) SD with range (82.50 – 145.5), mean Height (Cm) was 171.7 (± 6.25) SD with range (158.0 – 185.0), mean BMI (Kg/m2) was 36.17 (± 4.15) SD with range (29.30–43.40), mean Waistcircumference 113.1 (±7.64) SD with range (92.0 – 129.0). There were 37(74.0%) with Co-morbidity. 10(20.0%) have DM, 11(22.0%) have HTN, 11(22.0%) have CDK and 5(10.0%) have COPD. Conclusion That the combination of Fibroscan and, APRI, FGF-21 and FIB-4 methods provides a valuable approach for assessing liver fibrosis in NAFLD patients. This can eliminate the need for liver biopsy in patients without clear indication. In addition, several recent studies have also validated the used of non-invasive markers in the diagnosis of NAFLD. The establishment of a national program for the recognition of NAFLD is therefore essential to reduce the risk of liver disease progression.

Insulin Resistance in Pediatric Migraine

Abstract Background Migraine is a common complaint in the pediatric population with a prevalence ranging from 3% to 10%. Several studies among adult population defined a link between migraine and insulin resistance (IR), however data among pediatric population is scarce, thus the aim of the current study is to assess the relation between IR and migraine among pediatric patients with migraine. Patients and Methods A case control study that was conducted on children aged between 4 and 16 years; 30 were patients with migraine who were recruited from the pediatric neurology department and 40 were healthy. The diagnosis of migraine was according to the criteria of the International Classification of Headache Disorders (ICHD) -II criteria. Anthropometric measurements of all patients were assessed. Insulin resistance was assessed by Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) and Quantitative Insulin Sensitivity Check Index (QUICKI equation). Results The mean age of patients with migraine was 10.03 ± 2.16 years with male predominance. Most of the patients (80%) were pre-pubertal. Headache with aura was present in 13 (43.3%), family history was present in 24 (80%), bilateral headache was the most common among our patients (71.4%). There was significant increase in BMI among migraine group (P = 0.03). 50% of migraine patients were overweight, 20% were obese. Incidence of insulin resistance by HOMA-IR and by QUICKI was significantly higher among patients with migraine (P = 0.007 and 0.033) respectively. Conclusion based on our results, it can be concluded that migraine is associated with insulin resistance in 36.7% of patients.

Reallocating just 10 min to moderate-to-vigorous physical activity from other components of 24-hour movement behaviors improves cardiovascular health in adults

BackgroundAs components of a 24-hour day, sedentary behavior (SB), physical activity (PA), and sleep are all independently linked to cardiovascular health (CVH). However, insufficient understanding of components’ mutual exclusion limits the exploration of the associations between all movement behaviors and health outcomes. The aim of this study was to employ compositional data analysis (CoDA) approach to investigate the associations between 24-hour movement behaviors and overall CVH.MethodsData from 581 participants, including 230 women, were collected from the 2005–2006 wave of the US National Health and Nutrition Examination Survey (NHANES). This dataset included information on the duration of SB and PA, derived from ActiGraph accelerometers, as well as self-reported sleep duration. The assessment of CVH was conducted in accordance with the criteria outlined in Life’s Simple 7, encompassing the evaluation of both health behaviors and health factors. Compositional linear regression was utilized to examine the cross-sectional associations of 24-hour movement behaviors and each component with CVH score. Furthermore, the study predicted the potential differences in CVH score that would occur by reallocating 10 to 60 min among different movement behaviors.ResultsA significant association was observed between 24-hour movement behaviors and overall CVH (p < 0.001) after adjusting for potential confounders. Substituting moderate-to-vigorous physical activity (MVPA) for other components was strongly associated with favorable differences in CVH score (p < 0.05), whether in one-for-one reallocations or one-for-remaining reallocations. Allocating time away from MVPA consistently resulted in larger negative differences in CVH score (p < 0.05). For instance, replacing 10 min of light physical activity (LPA) with MVPA was related to an increase of 0.21 in CVH score (95% confidence interval (95% CI) 0.11 to 0.31). Conversely, when the same duration of MVPA was replaced with LPA, CVH score decreased by 0.67 (95% CI -0.99 to -0.35). No such significance was discovered for all duration reallocations involving only LPA, SB, and sleep (p > 0.05).ConclusionsMVPA seems to be as a pivotal determinant for enhancing CVH among general adult population, relative to other movement behaviors. Consequently, optimization of MVPA duration is an essential element in promoting overall health and well-being.
