ABSTRACT

BACKGROUND: Attention-Deficit Hyperactivity Disorder (ADHD) is a complex disease that negatively impacts the social and academic/occupational activities of children and is more common in boys than in girls.

METHODS: This case-control study aimed to assess the association between some environmental risk factors and ADHD among children in Alexandria, Egypt. It was carried out at the outpatient clinics of El Shatby Pediatric University Hospital in Alexandria, Egypt, with 252 children (126 cases and 126 controls). Hair samples were collected for analysis of lead and manganese levels using Atomic Absorption Spectrophotometer. A pre-designed interview questionnaire was used to determine the important environmental risk factors that may be related to ADHD.

RESULTS: Children from parents with low levels of education, living in crowded houses, and occupational exposure to chemical agents were found to be risk factors for ADHD. The mean ± SD hair lead level in ADHD children was 2.58 ± 1.95, while in controls was 1.87 ± 0.92, with a statistically significant difference (p < 0.001). The mean ± SD hair manganese level in ADHD children was 2.10 ± 1.54, while in controls was 1.11 ± 0.69, with a statistically significant difference (p < 0.001). The logistic regression model revealed that six factors had a significant association with ADHD: using of newspapers to wrap food 3 or more times a week (adjusted odds ratio (AOR) = 105.11, 95% CI: 11.18-988.26), daily TV watching by child for more than 5 h (AOR = 63.96, 95% CI: 2.56-1601.32), child’s eating commercially packed noodles 3 times or more per week (AOR = 57.73, 95% CI: 3.77-593.93), using unpackaged flour in cooking (AOR = 44.47, 95% CI: 1.83-629.80), eating sweets daily by child (AOR = 6.82, 95% CI: 1.23-37.94), and lastly elevated hair Manganese level (AOR = 3.57, 95% CI: 1.24-10.29).

CONCLUSIONS: ADHD is a multi-factorial disorder, where many environmental risk factors contribute to its development. Future efforts to determine the best preventive strategy in Egypt must be based on a better knowledge of the role of environmental risk factors in the etiology of the disorder. Eliminating non-essential uses of lead and providing public education regarding the importance of safe disposal of lead-acid batteries and computers are necessary.

ABSTRACT

BACKGROUND: Early and continuous exposure to painful stimuli in premature infants leads to short-and long-term complications. Listening to white noise is an accessible and inexpensive non-invasive method that can be used as a safe nursing intervention in hospitals. This study aimed to assess white noise’s effect on premature Infants’ physiological parameters during peripheral intravenous catheter insertion.

METHODS: The present experimental study was conducted on 40 premature Infants. From 5 min before Indwelling catheters to 10 min after, white noise was played through headphones to infants at a controlled volume in the test group. Using a monitor, physiological parameters were recorded from 10 min before to 30 min after the Indwelling catheter. Statistical analysis was done through the SPSS version 27 software program.

RESULTS: Regarding respiratory rate, there was no statistically significant difference between the two groups in the first, second, and sixth stages (p < 0.05). However, in the third, fourth, and fifth stages, RR in the control group was significantly higher than the test group (p ≤ 0.05). In terms of mean arterial blood pressure, there was no statistically significant difference between the two groups in any of the stages (p < 0.05). In terms of heart rate, there was no statistically significant difference between the two groups in the first, second, and sixth stages (p < 0.05). However, in the third, fourth, and fifth stages, HR in the control group was significantly higher than the test group (p ≤ 0.05). Regarding oxygen saturation percentage, there was no statistically significant difference between the two groups in the first, second, third, and sixth stages (p < 0.05). In contrast, in the fourth and fifth stages, the oxygen saturation percentage in the test group was significantly higher than in the control group (p < 0.05).

CONCLUSIONS: Although in both groups the painful procedure led to an increase in physiological variables (respiratory rate, heart rate, mean arterial blood pressure) and a decrease in blood oxygen saturation, in the test group these variables approached their initial state more quickly within half an hour after exposure to white noise. This confirms that the effect of white noise on the improvement of physiological variables is gradual.

ABSTRACT

BACKGROUND: The metabolic score for visceral fat (METS-VF) is a recently identified index for evaluating visceral fat, also referred to as abdominal obesity. The skeletal muscle mass index (SMI) serves as a critical measure for assessing muscle mass and sarcopenia. Both obesity and the reduction of muscle mass can significantly affect human health. However, research exploring the relationship between METS-VF and SMI remains limited. This study aims to investigate whether a association exists between these two indices, and if so, to elucidate the nature of their interactions.

METHODS: We conducted a cross-sectional study using data from the NHANES database, focusing on U.S. adults aged 20 years and older from 2013 to 2018. Controlling for relevant covariables, we primarily investigated the association between METS-VF and SMI values utilizing weighted multivariable linear regression models. Additionally, we assessed the diagnostic efficacy of METS-VF for sarcopenia.

RESULTS: A total of 3,594 participants were included in this study for analysis. The final adjusted model from the weighted multivariable linear regression indicated that METS-VF was negatively associated with SMI, with a coefficient of β = -0.13 (95% CI: -0.14, -0.12; P < 0.001). Subgroup analyses further demonstrated that this negative association was consistent across different populations. Notably, the negative association varied significantly between diabetic and nondiabetic population, as well as among populations classified by different BMI categories. Additionally, threshold effect analysis identified a significant inflection knot at 6.33. The characteristic curves of the subjects’ work illustrated that, compared to other indicators, METS-VF exhibited excellent diagnostic efficacy for sarcopenia, with an area under the curve (AUC) of 0.825.

CONCLUSION: Our results indicate that METS-VF is negatively correlated with SMI among adults in the United States, suggesting that visceral obesity exerts a detrimental effect on muscle mass. Furthermore, METS-VF shows potential as a valuable indicator for assessing SMI and sarcopenia. These findings underscore the importance of considering lipid metabolism disorders in the context of muscle health and highlight the potential for developing prevention strategies for sarcopenia.

ABSTRACT

BACKGROUND: Since the beginning of the 21st century, China’s economy has experienced rapid growth, resulting in a steady improvement in its citizens’ living standards. However, alongside the emergence of modern civilization-related health issues, the overall physical fitness of the population has been declining. In the final year of 2019, a global COVID-19 pandemic emerged and persisted for three years, causing a significant diminution in human physical well-being. This article aims to delve into the changes in the physical fitness of college students over the past decade and anticipates future trends.

METHODS: A total of 58,472 university students aged 16-23 from 16 prefecture-level cities in Anhui province were recruited for this study. Total ten physical fitness indicators were tested: body height, body weight, vital capacity, standing long jump, sit-and-reach, 50-m dash, 1000 m run and pull-up (for boys), and 800 m run and sit-ups (for girls).The data were analyzed using one-way ANOVA, LSD tests, and Pearson’s correlations.

RESULTS: The overall physical fitness scores of college students ranged from 68.71 (2023) to 71.13 (2019) during the last decade, with girls consistently demonstrating superior performance in physical tests. There was a statistically significant difference in physical fitness scores between the periods of 2015-2022 and 2023 (p < 0.05). When dividing the total physical fitness scores into four levels, a noteworthy downward trend was observed in the pass grade, while the other three grades exhibited an increasing trend year by year. Compared to the year of 2019, there has been a substantial decline in the physical fitness levels of college students, along with a notable uptick of “failed” candidates, in the year of 2020.In terms of individual physical fitness, boys outperformed girls in all physical testing items except for sit-and-reach, and significant differences were observed in most years for both boys and girls. Additionally, a consistent downward trend was observed in the proportion of underweight and normal weight students, while the proportion of overweight (increased by 2.1 times) and obese (increased by 4.4 times) students showed a marked upward trend from 2014 to 2023.

CONCLUSIONS: It is imperative to allocate special focus to the profound ramifications of the three-year COVIE-19 pandemic on the physical well-being of college students. In 2024, it is anticipated that the proportion of overweight and obese college students will increase, along with a continued increase in body height and vital capacity. However, there will be a notable increase in the time taken to complete the 50-meter dash and the 1000-meter/800-meter run. Conversely, a decline is forecasted for the performance in standing long jump, sit-and-reach, and pull-ups/sit-ups exercises, with an accelerating rate of deterioration. It is crucial to promptly identify the underlying reasons for the deteriorating physical fitness among college students, particularly in relation to obesity, and to implement effective measures promptly to address this issue.

ABSTRACT

The incidence of keratinocyte carcinoma (KC) is rising globally, significantly burdening healthcare resources. Treatment options include medical treatment, non-invasive procedures, and surgery, each associated with their distinct benefits and risks. With advanced treatment, the procedures become increasingly invasive for the patients and expensive for the society. This nationwide cohort study examined the current surgical treatment trends for KC, including factors influencing the likelihood of undergoing reconstructive surgery. We retrieved data on all first-time incidences of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) that were treated at a Danish hospital in the calendar years 2007-2021, corresponding to 34,205 patients with BCC and 17,625 patients with SCC. Descriptive statistics were used to study the development of reconstructive surgery, and the associations between demographic factors, tumor-related factors, and comorbidity, and the use of reconstructive procedures were analyzed using multivariable logistic regression. Among the patients, 26% with BCC and 35% with SCC received reconstructive surgery as part of their surgical treatment. The volume of surgical treatment increased with time, but the proportion of reconstructive procedures for surgically treated KC decreased in the study period. The likelihood of undergoing reconstructive surgery was higher for men and increased with age. Patients with BCC and high comorbidity burden or those who stayed in assisted living facilities were less likely to undergo reconstructive surgery. This was not the case for patients with SCC. The rapid increase in surgical treatment for KC at Danish hospitals, with a notable increase in reconstructive procedures, reflects the global development in KC cases and highlights the continued need for tailored management strategies.

ABSTRACT

Tea (Camellia sinensis) is one of the most popular nonalcoholic beverages in the world, second only to water. Six main types of teas are produced globally: green, white, black, oolong, yellow, and Pu-erh. Each type has a distinctive taste, quality, and cultural significance. The health-promoting effects of tea are attributed to the complex metabolite compositions present in tea leaves. These metabolite compositions vary in response to different factors. In addition to manufacturing processes in processed tea, the primary factors influencing variations of fresh tea leaf metabolites include genetics, cultivation management, and environmental conditions. Metabolomics approaches, coupled with high-throughput statistical analysis, offer promising tools for the comprehensive identification and characterization of tea leaf metabolites according to growing conditions, cultivation practices, manufacturing processes, seasonality, climate, cultivars, and geography. This review highlights the distinctive variations in fresh tea leaf metabolites, which change in response to various factors, using a metabolomics approach, which are also extended to various processed teas.

ABSTRACT

Multiple respiratory viruses can concurrently or sequentially infect the respiratory tract, making their identification crucial for diagnosis, treatment, and disease management. We present a label-free diagnostic platform integrating surface-enhanced Raman scattering (SERS) with deep learning for rapid, quantitative detection of respiratory virus coinfections. Using sensitive silica-coated silver nanorod array substrates, over 1.2 million SERS spectra are collected from 11 viruses, nine two-virus mixtures, and four three-virus mixtures at various concentrations in saliva. A deep learning model, MultiplexCR, is developed to simultaneously predict virus species and concentrations from SERS spectra. It achieves an impressive 98.6% accuracy in classifying virus coinfections and a mean absolute error of 0.028 for concentration regression. In blind tests, the model demonstrates consistent high accuracy and precise concentration predictions. This SERS-MultiplexCR platform completes the entire detection process in just 15 min, offering significant potential for rapid, point-of-care diagnostics in infection detection, as well as applications in food safety and environmental monitoring.

ABSTRACT

BACKGROUND: Despite the increasing popularity of electronic devices, the longitudinal effects of daily prolonged electronic device usage on brain health and the aging process remain unclear.

OBJECTIVE: The aim of this study was to investigate the impact of the daily use of mobile phones/computers on the brain structure and the risk of neurodegenerative diseases.

METHODS: We used data from the UK Biobank, a longitudinal population-based cohort study, to analyze the impact of mobile phone use duration, weekly usage time, and playing computer games on the future brain structure and the future risk of various neurodegenerative diseases, including all-cause dementia (ACD), Alzheimer disease (AD), vascular dementia (VD), all-cause parkinsonism (ACP), and Parkinson disease (PD). All the characteristics of using mobile phones and playing computer games were collected through face-to-face interviews at baseline, and outcomes were extracted from the algorithmic combinations of self-reported medical conditions, hospital admissions, and death registries. In addition, a group of participants underwent magnetic resonance imaging (MRI) at follow-up. Cox regression and linear regression were performed.

RESULTS: The study included over 270,000 participants for risk analysis, with a mean baseline age of approximately 55.85 (SD 8.07) years. The average follow-up duration was approximately 13.9 (SD 1.99) years. Lengthy mobile phone use was associated with a reduced risk of ACD (2-4 years: hazard ratio [HR] 0.815, 95% CI 0.729-0.912, P<.001; 5-8 years: HR 0.749, 95% CI 0.677-0.829, P<.001; >8 years: HR 0.830, 95% CI 0.751-0.918, P<.001), AD (5-8 years: HR 0.787, 95% CI 0.672-0.922, P=.003), and VD (2-4 years: HR 0.616, 95% CI 0.477-0.794, P<.001; 5-8 years: HR 0.729, 95% CI 0.589-0.902, P=.004; >8 years: HR 0.750, 95% CI 0.605-0.930, P=.009) compared to rarely using mobile phones. Additionally, lengthy mobile phone use was linked to a decreased risk of ACP (5-8 years: HR 0.747, 95% CI 0.637-0.875, P<.001; >8 years: HR 0.774, 95% CI 0.663-0.904, P=.001) and PD (5-8 years: HR 0.760, 95% CI 0.644-0.897, P=.001; >8 years: HR 0.777, 95% CI 0.660-0.913, P=.002) in participants older than 60 years. However, higher weekly usage time did not confer additional risk reduction compared to lower weekly usage of mobile phones. The neuroimaging analysis involved 35,643 participants, with an average duration of approximately 9.0 years between baseline and neuroimaging scans. Lengthy mobile phone use was related to a thicker cortex in different areas of the brain.

CONCLUSIONS: Lengthy mobile phone use is associated with a reduced risk of neurodegenerative diseases and improved brain structure compared to minimal usage. Our research provides valuable background knowledge for future studies on the impact of modern electronic devices on brain health.

ABSTRACT

BACKGROUND: Low back pain (LBP) is highly prevalent and disabling, especially in agriculture sectors. However, there is a gap in LBP prevention and intervention studies in these physically demanding occupations, and to date, no studies have focused on horticulture workers. Given the challenges of implementing interventions for those working in small businesses, self-management offers an attractive and feasible option to address work-related risk factors and manage LBP.

OBJECTIVE: This study will (1) investigate the effectiveness of self-management strategies for nursery and landscape workers by comparing within-subject control and intervention periods and (2) determine if adoption and effectiveness differs between participants randomly assigned to review self-management videos only and those who also receive multimodal implementation support. We will also identify contextual factors impacting effectiveness and implementation.

METHODS: A pragmatic, mixed methods, hybrid effectiveness and implementation design will be used to compare back pain with work tasks, disability, medication and substance use, and psychological factors between a baseline control and intervention periods. We aim to recruit 122 English- and Spanish-speaking horticulture workers with back pain, 30 supervisors, and 12 focus group participants. Participants will review short video modules designed to increase awareness of opioid risk and introduce self-management and ergonomic choices and use 1 self-management and 1 ergonomic strategy for 10 weeks. They will be randomly assigned to 2 implementation groups: video modules only or video + multimodal personalized support (checklist guidance, review of video feedback for ergonomic problem-solving, and text message reminders). Questionnaires will be administered at 3-month time points: baseline, pre- and postintervention, and at 3 and 6 months. Qualitative analysis of field notes, open-ended comments, and focus groups will expand understanding of results with comprehensive documentation of the context, barriers and facilitators, and reasons for adoption.

RESULTS: The project was funded on September 29, 2023 (Centers for Disease Control and Prevention National Institute of Occupational Health and Safety, CDC NIOSH; U54OH011230-07S1), as a core research grant for the Southeast Coastal Center for Agricultural Health and Safety. The design, creation, and editing of English and Spanish videos was completed in June 2024 after comprehensive formative evaluation. Enrollment began in June 2024 with anticipated completion in 2027.

CONCLUSIONS: We hypothesize that both self-management interventions will result in reductions in work task pain and disability and that the video enhanced with multimodal personalized support will result in greater reductions than the video alone. If self-management is effective, mitigating pain positively impacts quality of life, productivity, and retention, while increasing the use of nonpharmacological alternatives to opioids addresses an important public health issue. Implementation aims will help inform reasons for results, barriers and facilitators, and potential for similar interventions in these and similar industries with physically challenging outdoor work.

ABSTRACT

BACKGROUND: Social behavioral research studies have increasingly shifted to remote recruitment and enrollment procedures. This shifting landscape necessitates evolving best practices to help mitigate the negative impacts of deceptive attempts (eg, fake profiles and bots) at enrolling in behavioral research.

OBJECTIVE: This study aimed to develop and implement robust deception detection procedures during the enrollment period of a remotely conducted randomized controlled trial.

METHODS: A 32-group (2×2×2×2×2) factorial design study was conducted from November 2021 to September 2022 to identify mobile health (mHealth) survey design features associated with the highest completion rates of smartphone-based ecological momentary assessments (n=485). Participants were required to be at least 18 years old, live in the United States, and own an Android smartphone that was compatible with the Insight app that was used in the study. Recruitment was conducted remotely through Facebook advertisements, a 5-minute REDCap (Research Electronic Data Capture) prescreener, and a screening and enrollment phone call. The research team created and implemented a 12-step checklist (eg, address verification and texting a copy of picture identification) to identify and prevent potentially deceptive attempts to enroll in the study. Descriptive statistics were calculated to understand the prevalence of various types of deceptive attempts at study enrollment.

RESULTS: Facebook advertisements resulted in 5236 initiations of the REDCap prescreener. A digital deception detection procedure was implemented for those who were deemed pre-eligible (n=1928). This procedure resulted in 26% (501/1928) of prescreeners being flagged as potentially deceptive. Completing multiple prescreeners (301/501, 60.1%) and providing invalid addresses (156/501, 31.1%) were the most common reasons prescreeners were flagged. An additional 1% (18/1928) of prescreeners were flagged as potentially deceptive during the subsequent study screening and enrollment phone call. Reasons for exclusion at the screening and enrollment phone call level included having an invalid phone type (6/18, 33.3%), completing multiple prescreeners (6/18, 33.3%), and providing an invalid address (5/18, 27.7%). This resulted in 1409 individuals being eligible after all deception checks were completed. Postenrollment social security number checks revealed that 3 (0.6%) fully enrolled participants out of 485 provided erroneous social security numbers during the screening process.

CONCLUSIONS: Implementation of a deception detection procedure in a remotely conducted randomized controlled trial resulted in a substantial proportion of cases being flagged as potentially engaging in deceptive attempts at study enrollment. The results of the deception detection procedures in this study confirmed the need for vigilance in conducting remote behavioral research in order to maintain data integrity. Implementing systematic deception detection procedures may support study administration, data quality, and participant safety in remotely conducted behavioral research.
