Locomotion is essential to most of the living organisms. The nematode Teratorhabditis palmarum (Gerber & Giblin-Davis, 1990), must be able to accommodate its locomotory gait to its physical environment. Particularly, when crawl on a solid surface, it shows forward movement as the contraction waves propagates from anterior to the posterior region. In the present study, we analyzed the locomotory behavior of T. palmarum on agar by using computational worm-tracking system and mathematical tools. Our tracking system was made to assist worms that travel a vast area with recurrent turns and reversals at high speeds. The locomotory parameters studied were velocity, wavelength, amplitude, angle of bending, curvature map, forward, reversal, omega and pause that was extracted from a two min video recording. Here, we examined the locomotory behaviour (movement and wave characteristic) of two, six and ten days old nematodes. In movement characteristic, except pause which increases; forward wave, backward wave and omega wave decrease significantly. In wave characteristic, wavelength and amplitude increase while average velocity and bending angle decrease significantly. Locomotion was observed between various age groups and it was concluded that as the nematodes aged, mild locomotory deficits appeared that were enough to reduce behavioral activity. Overall, our result provides the detailed analysis of locomotion and its dynamics in enabling better understand the mechanism of muscle ageing. [ABSTRACT FROM AUTHOR]

Aim and objectives: In forensic age estimation e.g. for judicial proceedings surpassed age thresholds can be legally relevant. To examine age related differences in skeletal development the recommendations by the Study Group on Forensic Age Diagnostics (AGFAD) are based on ionizing radiation (among others orthopantomograms, plain x-rays of the hand). Vieth et al. and Ottow et al. proposed MRI-classifications for the epiphyseal-diaphyseal fusion of the knee joint to define different age groups in healthy volunteers. The aim of the present study was to directly compare these two classifications in a large German patient population. Materials and methods: MRI of the knee joint of 900 patients (405 female, 495 male) from 10 to 28 years of age were retrospectively analyzed. Acquired T1-weighted turbo spin-echo sequence (TSE) and T2-weighted sequence with fat suppression by turbo inversion recovery magnitude (TIRM) were analyzed for the two classifications. The different bony fusion stages of the two classifications were determined and the corresponding chronological ages assigned. Differences between the sexes were analyzed. Intra- and inter-observer agreements were determined using Cohen's kappa. Results: With the classification of Ottow et al. it was possible to determine completion of the 18th and 21st year of life in both sexes. With the classification of Vieth et al. completion of the 18th year of life for female patients and the 14th and 21st year of life in both sexes could be determined. The intra- and inter-observer agreement levels were very good (κ > 0.82). Conclusion: In the large German patient cohort of this study it was possible to determine the 18th year of life with for both sexes with the classification of Ottow et al. and for female patients with the classification of Vieth et al. It was also possible to determine the 21st year of life for all bones with the classification of Ottow et al. and for the distal femur with the classification of Vieth et al. [ABSTRACT FROM AUTHOR]

Cranial vault thickness (CVT) and its variations provide valuable insights into an individual's biological attributes such as age and sex. This paper aimed to assess the correlations of CVT with age and sex and develop a regression model for age estimation in Malaysian subadults using computed tomography (CT) images. A total of 521 CT images (male/female: 279/242; age range: 0–20 years; Malay/Chinese/Indian: 221/145/155) were included in the study. Correlations of CVT measurements with age and sex, including frontal bone thickness (FBT), occipital bone thickness (OBT), left parietal bone thickness (LPBT), and right parietal bone thickness (RPBT) were assessed and regression formulae were developed for age estimation in subadults. A significant correlation between CVT measurements and age was demonstrated (p < 0.001). Age estimation was most accurate in the younger age group (< 2 years) at frontal and occipital, and accuracy decreases in the older age groups. Additionally, sexual dimorphism was evident in the frontal and parietal bone thickness within the age range of 3–6 years and 16–20 years, respectively. In conclusion, the findings suggested CVT measurements could be used to corroborate other age estimation methods for subadults. [ABSTRACT FROM AUTHOR]

Fingernails can act as important forensic evidence as they can be a source of DNA that may link the victim or accused to the crime scene and may also contain traces of drugs such as cocaine and heroin, in regular users. Moreover, previous studies have shown that analyzing fingernails with various techniques can reveal important information, such as age and sex. In this work, ATR-FTIR spectroscopy with chemometric tools has been used to estimate the age and sex from fingernails by analyzing 140 fingernail samples (70 males, and 70 females) collected from volunteers aged between 10 and 70 years old. The amide bands obtained from spectra confirmed the presence of keratin proteins in the samples. PCA and PLS-R were used for the classification of samples. For sex estimation, samples were divided into four categories based on age groups, followed by the differentiation of sex in each group. Similarly, for age estimation, all samples were divided into two sets based on male and female followed by differentiation of age groups in each set. The result showed that PLS-R was able to differentiate fingernail samples based on sex in groups G1, G2, G3, and G4 with R-square values of 0.972, 0.993, 0.991, and 0.996, respectively, and based on age in females, and males with R-square values of 0.93 and 0.97, respectively. External validation and blind tests were also performed which showed results with 100% accuracy. This approach has proved to be effective for the estimation of sex and age from fingernail samples. Highlights: • Estimation of age and sex using fingernails via ATR-FTIR and chemometrics. • PLS-R successfully estimated age and sex using fingernails with high R-square values. • Blind and external validation tests illustrated 100% accuracy. • The present approach is quick, and non-destructive with minimal or no sample preparation.

Background: Seasonal influenza is prevented through annual vaccination, especially in children and older adults. These vaccines are annually updated based on World Health Organization recommendations and require continuous safety monitoring. Objective: We assessed the frequency and severity of adverse events within 7 days of administering GSK's inactivated quadrivalent seasonal influenza vaccine (IIV4) in Belgium, Germany, and Spain during the 2022/2023 influenza season. Methods: In this enhanced safety surveillance study, adults who received GSK's IIV4 and parents/guardians/legally acceptable representatives of vaccinated children (aged 6 months–17 years) were invited to complete adverse drug reaction cards reporting adverse events within 7 days post-vaccination. Results: In total, 1332 participants (53.6% female) received at least one dose of GSK's IIV4, including 43 children who received two doses. Overall, 97.8% of adverse drug reaction cards were completed and returned in the study. All participants in Belgium were adults, while 54.7% and 7.4% in Spain and Germany, respectively, were pediatric participants aged 6 months–17 years. After Dose 1, across all age groups, 49.8% of participants reported at least one adverse event. The most common adverse events (cumulative frequency >5%) following Dose 1 were injection-site pain (37.6%), fatigue (15.0%), headache (13.2%), injection-site swelling (9.3%), myalgia (7.6%), and injection-site erythema (7.4%). Across all countries, adverse events were most common in adults aged 18–65 years (59.7%), followed by those aged 3–17 years (47.0%), >65 years (35.7%), and 6–35 months (23.5%). After Dose 2, 18.6% of participants reported at least one adverse event, with general disorders and administration site conditions again being the most frequent. Conclusions: Across all age and risk groups for serious disease, no serious adverse events related to GSK's IIV4 were reported within 7 days post-vaccination. This study supports and confirms the acceptable safety profile of GSK's IIV4 across all recommended age groups. Clinical Trial Registration: ClinicalTrials.gov number: not applicable.

This study analyzes the epidemiology of pediatric drowning in Israel from 2010 to 2022, focusing on differences across age groups, sex, and regions. We conducted a retrospective cohort study using data from the Ministry of Health's administrative databases, covering all children aged 0–17 years who were seen in the emergency department, discharged after hospitalization, or died at the scene due to drowning, excluding cases of intentional harm or suicide. The primary outcome was the annual drowning rate per 100,000 children, categorized by age, sex, and region, along with hospitalization duration, intensive care unit admissions, and mortality rates. A total of 2101 drowning incidents were identified, with 9% resulting in death. Higher drowning rates were found in younger children (1–4 years) and teenagers (15–17 years), with notable differences by sex. Drowning rates were higher in coastal regions and more frequent during winter and spring. An increase in drowning rates was observed over the last 3 years of the study (2020–2022). Children hospitalized for more than 3 days had significantly higher mortality rates, both in general wards and intensive care units. Conclusions: Pediatric drowning is a persistent public health concern in Israel, with distinct seasonal, regional, age-specific, and sex-specific patterns in incidence and mortality. This study underscores the need for a comprehensive prevention strategy that includes year-round public education, environmental safety measures, and targeted interventions for high-risk groups to reduce drowning incidents and fatalities among children effectively. What is Known: • Pediatric drowning represents a significant public health challenge globally, with varying rates. • In Israel, pediatric drowning is the second leading cause of death from all injury-related deaths. Thus far, the measures and interventions to reduce fatalities were not proven effective enough. What is New: • Pediatric drowning in Israel, with a 9% mortality rate, revealed a biphasic rate varied by sex and is higher in coastal regions and during winter and spring. • There was a notable increase in drowning incidents during the last 3 years of the study period (2020–2022), coinciding with the COVID-19 pandemic.

To stratify groups of infants by gestational age and identify the lower limit of normal (LLN) of the cross-sectional area of peripheral muscles as well as diaphragmatic excursion and thickness and parasternal activation during spontaneous respiration in full-term and preterm newborns. A cross-sectional study was conducted at a neonatal unit. Preterm newborns (PTNBs) with gestational age of 28 to 366/7 weeks and full-term newborns (NBs) with gestational age of 37 to 416/7 weeks, clinically and hemodynamically stable, breathing ambient air with no signs of respiratory distress were included. NBs on oxygen therapy, those with known genetic syndromes, malformations of the nervous system and those having undergone surgery were excluded. Ultrasound was performed over the rectus femoris, tibialis anterior, and biceps brachii muscles (cross-sectional area) and diaphragm (thickness and excursion). One hundred twenty NBs were stratified based on gestational age (< 30 weeks [n = 25]; 31 to 35 weeks [n = 51]; 37 to 41 6/7 weeks [n = 44]). Significant differences were found in the cross-sectional area of the rectus femoris muscles and thigh circumference of NBs > 37 weeks compared to the other 2 groups (p < 0.05). Differences were found in diaphragm thickness and excursion between the groups with gestational age > 37 weeks and < 30 weeks. Greater activation of the parasternal muscles was found in the PTNBs. With regard to LLN, significant differences were found between the groups with gestational age > 37 weeks and < 30 weeks for all variables analyzed and between the group with gestational age > 37 weeks and other 2 groups for the cross-sectional area of the rectus femoris, diaphragmatic excursion, and diaphragm contraction velocity. Differences were found among the groups in the size of peripheral muscles as well as diaphragm thickness and excursion. Moreover, greater activation of the parasternal muscle was found in NBs with gestational age < 30 weeks. This study establishes normal values of ultrasound measures for full-term and preterm newborns. [ABSTRACT FROM AUTHOR]

Bronchopulmonary dysplasia (BPD) poses a significant challenge as the most common late morbidity of preterm infants. This study aimed to evaluate airway abnormalities in infants with BPD who underwent flexible bronchoscopy (FB) to gain insights into the prevalence of upper airway obstruction and associated complications. A retrospective case–control study was conducted on BPD patients who underwent FB at a tertiary center between 2013 and 2023. BPD patients were matched (1:3) with a reference group based on age, gender, and ethnicity, who also had undergone FB. Demographic data, comorbidities, indications for FB, findings, and complications during and after FB were collected. The study included 50 BPD patients (mean age 1.26 ± 0.9 years, 58% males), and 150 controls. As expected, BPD patients had a lower gestational age, lower birth weight, and longer hospitalizations and were treated with more medications. Abnormal bronchoscopy findings were significantly more common in the BPD group compared to the reference group, with an increased rate of turbinate hypertrophy (OR [95% CI]: 3.44 [1.27–9.37], P = 0.014), adenoid hypertrophy (OR: 2.7 [1.38–5.29], P = 0.004), lingual tonsils (OR: 5.44 [1.29–27.4], P = 0.0024), subglottic stenosis (OR: 6.95 [2.08–27.1], P = 0.002), and tracheomalacia (OR: 2.98 [1.06–8.19], P = 0.034). Complications including desaturation (OR: 3.89 [1.32–11.7], P = 0.013) and PICU admission (OR: 16.6 [2.58–322], P = 0.011) were more frequent in the BPD than in the reference group. Conclusion: The study revealed a high prevalence of structural anomalies leading to upper airway obstruction and complications in infants with BPD undergoing FB. These findings emphasize the importance of careful consideration and preparation for bronchoscopic procedures in this vulnerable population. What is known: • Bronchopulmonary dysplasia (BPD) represents the most prevalent late morbidity among preterm infants. • Preterm infants diagnosed with BPD frequently undergo diagnostic procedures, including flexible and rigid bronchoscopies, to identify structural pathologies within the respiratory tract. What is new: • A significantly higher prevalence of structural anomalies leading to upper airway obstruction was observed in the BPD group compared to controls. • The incidence of complications during flexible bronchoscopy was higher in the BPD group than in controls.

Objectives: The aim of this study was to analyze the influence of patients´ age on perioperative complications in impacted third molar surgery and how established risk factors are affected by age. Materials and methods: The clinical findings, digital panoramic radiographs and perioperative data of 200 patients (554 impacted third molars) that had been subjected to tooth extraction, from July 2023 until July 2024, were analyzed. Perioperative complications (Inferior alveolar nerve (IAN) hypesthesia, oroantral communication (OAC), lingual nerve (LN) hypesthesia, postoperative bleeding, postoperative infection) as well as impaction patterns and risk factors (angulation type, bone coverage, depth- and risk scores) were analyzed by age (cut-off 30 years). Results: The population was divided into two groups by age (Group A = ≥ 30 years (n = 52) vs. Group B = < 30 years (n = 148)). Upper third molars showed significantly deeper bone coverage, higher depth scores, higher risk scores and different angulation types in patients aged < 30 years. Mandibular third molars showed significantly deeper bone coverage, higher depth scores, higher risk scores according and different angulation types in patients aged ≥ 30 years. However, IAN hypesthesia, LN hypesthesia, postoperative bleeding and postoperative infection did not show any significant differences regarding patients' age. Conclusion: The current findings suggest that age (cut-off 30 years) does not statistically correlate with a higher risk for postoperative complications in impacted third molar surgery in contrast to recent publications. Clinical relevance: In contrast to recent publications, the present study falsified a positive correlation between patients' age and the occurrence of postoperative complications in impacted third molar surgery. Therefore, other risk factors should be investigated in order to minimize these procedure specific complications. [ABSTRACT FROM AUTHOR]

The adoption of mobile health technology can assist in enhancing the quality of life of elderly people. Over the last few years, though mHealth research has expanded, the usage of mHealth applications among elderly is still minimal. This study aims to evaluate mobile user interfaces in mHealth applications and elicit the key ageing barriers that limit the use of such apps among the elderly. The Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) technique was used whereby 28 papers were identified and examined out of 742. In addition to the systematic review, an experiment of using 5 existing mHealth apps was conducted with 10 individuals within the age group of 60–79 to determine additional ageing barriers and usage challenges. The Questionnaire for User Interface Satisfaction approach was used to prepare a questionnaire to assess the overall system satisfaction and was provided to participants after one week of usage. In this work, issues with the user interface that impact the elderly have been highlighted. Three important ageing barriers hindering the use of mHealth among the elderly have been identified via PRISMA, namely physical, cognitive and perspective. Empirical findings from the experiment carried out further consolidate the findings obtained from the PRISMA approach. This study's investigation emphasised the performance of older persons with mHealth apps, their needs and the challenges they confront when adopting mHealth technologies. As a result, technology designers will benefit from this information when developing and designing mHealth apps and services that are suitable for older adults. [ABSTRACT FROM AUTHOR]

We explored the intricate quantitative structure of household food waste and their corresponding life cycle greenhouse gas emissions from raw materials to retail utilizing a combination of household- and food-related economic statistics and life cycle assessment in Japan. Given Japan's status as a nation heavily impacted by an aging population, this study estimates these indicators for the six age brackets of Japanese households, showing that per capita food waste increases as the age of the household head increases (from 16.6 for the 20's and younger group to 46.0 kg/year for 70's and older in 2015) primarily attributed to the propensity of older households purchase of more fruits and vegetables. Further, the largest life cycle greenhouse gases related to food waste was 90.1 kg-CO2eq/year for those in their 60's while the smallest was 39.2 kg-CO2eq/year for 20's and younger. Furthermore, food waste and associated emissions are expected to decline due to future demographic changes imparted by an aging, shrinking population after 2020 until 2040. Specific measures focused on demographic shifts are crucial for Japan and other countries with similar dietary patterns and demographics to achieve related sustainable development goals through suppressing food waste and associated emissions under new dietary regimes. Given Japan's aging population, this study examines household food waste and life cycle greenhouse gas emissions for the six age brackets of Japanese households. Older households have higher food waste emissions than younger households. [ABSTRACT FROM AUTHOR]

Our research focuses on semen collection from 42 African penguin males, grouped by age, habituation levels, and reproductive season timing. We assess behavioral and physiological responses to dorso-abdominal massage, evaluating species-specific seminal traits using conventional and advanced methods. Positive behavioral responses corresponded with successful semen collection. Young and human-reared males exhibited more favorable behaviors, and samples containing spermatozoa were more likely collected during the reproductive season. Age did not influence sample collectability or spermatozoa presence, though mature males produced higher semen volumes. Young males exhibited more sperm morphological abnormalities, especially outside the breeding season. Sperm concentration and number per ejaculate showed no significant differences across age or seasonal groups. Young males had higher motile and progressive sperm percentages, while mature males had more static sperm. Additionally, percentages of live sperm and intact acrosomes were higher in mature males. Young males and samples from non-reproductive season presented more dead sperm with damaged acrosomes. Plasma membrane integrity positively correlated with age for live sperm and negatively for dying sperm. This research demonstrates the feasibility of semen collection from African penguins regardless of habituation level, fills the knowledge gap by describing sperm morphological abnormalities, and provides insights into using flow cytometry in Sphenisciformes.

Older age (≥ 65 years) is associated with impaired responses to influenza vaccination, leading to the preferential recommendation of MF59-adjuvanted (MF59Flu) or high-dose (HDFlu) influenza vaccines for this age group in the United States. Herein, we characterized transcriptomic profiles of CD4+ T cells isolated from 234 recipients (≥ 65 years) of either MF59Flu or HDFlu vaccine, prior to vaccination and 28 days thereafter. We identified 412 and 645 differentially expressed genes (DEGs) in CD4+ T cells of older adults after receiving MF59Flu and HDFlu, respectively. DEGs in CD4+ T cells of MF59Flu recipients were enriched in 14 KEGG pathways, all of which were downregulated. DEGs in CD4+ T cells of HDFlu recipients were enriched in 11 upregulated pathways and 20 downregulated pathways. CD4+ T cells in both vaccine groups shared 50 upregulated genes and 75 downregulated genes, all of which were enriched in 7 KEGG pathways. The remaining 287 and 520 DEGs were specifically associated with MF59Flu and HDFlu, respectively. Unexpectedly, none of these DEGs was significantly correlated with influenza A/H3N2-specific HAI titers, suggesting these DEGs at the individual level may have a limited role in protection against influenza. Our findings emphasize the need for further investigation into other factors influencing immunity against influenza in older adults. [ABSTRACT FROM AUTHOR]

The safety and efficacy of coronavirus disease 2019 (COVID-19) vaccination in patients diagnosed with Moyamoya disease (MMD) have not been established. Using National Health Insurance Service data, this study analyzed the occurrence of stroke-related events and mortality following COVID-19 vaccination among patients diagnosed with MMD from 2008 to 2020. Among 10,297 MMD patients, 296 (2.9%) experienced events and 175 (1.7%) died in 2021. Significant risk factors for events included ages 50–59 (Odds Ratio [OR] 3.29; P = 0.022) and 60 or above (OR 5.20; P = 0.001) (reference group: age in 20s), low BMI (OR 2.00; P = 0.011), previous stroke (OR 1.96; P < 0.001), and COVID-19 infection (OR 2.28; P = 0.034). Female (OR 0.64 [95% CI 0.50–0.82]; p = 0.011), revascularization surgery (RS) (OR 0.38 [95% CI 0.21–0.70]; p < 0.001), and vaccination (OR 0.17 [95% CI 0.13–0.22]; p < 0.001) were associated with reduced odds of stroke-related events. For mortality, significant risks were age over 60 (OR 7.09; P = 0.008), low BMI (OR 3.87; P = 0.001), and prior stroke (OR 1.74; p = 0.004), while being female, RS (OR 0.41; P = 0.022), and vaccination (OR 0.12; P < 0.001) were associated with a lower frequency of mortality. mRNA vaccines were associated with a significantly lower incidence of events, mortality, and COVID-19 infections compared to vector vaccines. COVID-19 vaccination is linked to reduced stroke-related events and mortality in MMD patients, with mRNA vaccines showing a significantly lower incidence compared to vector vaccines. COVID-19 infection raises the risk of events, underscoring the benefit of vaccination. [ABSTRACT FROM AUTHOR]

Background: This study aimed to assess body image dissatisfaction in Omani university students across gender and age and explore the potential impact of social media use on body image dissatisfaction. This cross-sectional online survey was responded by 482 Omani university students. The survey included socio-demographic data, a Social Media Activity Questionnaire, and a Body Dissatisfaction Scale. The participants were approached through promotion of the study on locally famous social media accounts. Results: The prevalence of body image dissatisfaction was higher in females compared to males (37.7% and 24%, respectively). Additionally, 53.6% of participants with a high body mass index reported high levels of body image dissatisfaction, while underweight participants reported the lowest body image dissatisfaction (21.3%). High social media use showed a significant correlation with body image dissatisfaction (p < 0.001); however, age did not exhibit a significant association with body image dissatisfaction. Concerns related to being overweight and not having clear skin were the most common body features associated with body image issues. Conclusion: Higher levels of body image dissatisfaction were found with high social media use. The study also identified a higher prevalence of body image dissatisfaction in females compared to males, with no significant differences across age groups. [ABSTRACT FROM AUTHOR]

High levels of particulate matters in the air are a major health issue in Middle East leading to adverse health effects. In this study, we have simultaneously investigated (i) the spatio-temporal distribution of ambient particulate matters in a city located in the Middle East (Khorramabad) over the time period 2021–2022; and (ii) PM2.5 and PM10-related carcinogenic and non-carcinogenic risk assessment to exposure. For the risk assessment, hourly PM2.5 and PM10 data were obtained from three monitoring stations located in the city. A methodology for risk assessment recommended by the United State Environmental Protection Agency was used for all age groups. The excess lifetime cancer risk (ELCR) and the hazard quotient (HQ) were estimated, and the backward trajectories were assessed by the Hybrid Single-Particle Lagrangian Integrated Trajectory model. The Aerosol Optical Depth from 0 to 1000 nm was applied to observe the variations of atmospheric aerosols. The results showed that the annual PM2.5 and PM10 mean concentrations during 2021 and 2022 were exceeded the World Health Organization limit value for human health protection. In 2021 and 2022, 2.2-148.3 and 1.3-134.4 cancers per 1,000,000 inhabitants can be related to ambient PM2.5 exposure. The HQ values for PM2.5 and PM10 were 4.7 and 1.3 in 2021, and 3.8 and 1.1 in 2022, i.e., the risk for human health is expected. To reduce the adverse health effects related to particulate matters, air emissions control strategies are required. [ABSTRACT FROM AUTHOR]

To assess the use of miniaturized percutaneous nephrolithotomy (mini-PCNL) for renal stones in children, as well as its safety and efficacy. Seventy-seven patients with more than 15 mm renal stones whose age was less than 15 years were enrolled in this prospective case-controlled study at Al-Ramadi Teaching Hospital, Ar Razi Private Hospital, and Ghazi Al-Hariri Hospital for Surgical Specialties, Anbar and Baghdad, Iraq. The study was conducted from January 2020 to January 2024. The group mentioned above served as group A, and it was compared to the control group (group B), which consisted of 70 adult patients aged 18–60 years. Patients in both groups underwent mini-PCNL. Gender, stone size and location, time of operation, stone-free rate, hemoglobin drop, need for blood transfusion, postoperative fever, associated visceral injury, and need for further interventions such as extracorporeal shock wave lithotripsy or flexible ureteroscopy (ESWL or FURS) were compared in both groups. The age of patients in group A ranged from 8 months to 15 years with a mean (4.30 ± 3.16), while in group B ranged from 18 to 60 years with a mean (36.3 ± 12.0), p-value 0.001. There were no statistically significant differences regarding gender distribution, stone size, and location, p-value > 0.05. The stone-free rate was 87.01% for group A and 88.57% for group B, with no statistical difference, p-value 0.773. Hemoglobin drop was 1.096 ± 0.412 for group A and 1.195 ± 0.110 for group B, p-value 0.046. Blood transfusion was needed in one case in each group with no statistical difference, p-value 0.946. The need for ESWL was 3 cases in group A, and 2 cases in group B, with no statistical difference between the two groups, p-value 0.729. The need for FURS was 4 cases in group A and 3 cases in group B, p-value 0.796. Operative time was 30 to 125 min in group A and 34 to 129 min in group B, p-value 0.941. Postoperative fever was seen in 23 cases in group A and 21 cases in group B, p-value 0.986. Minor liver injury was seen was seen in one case in each group. The use of mini-PCNL for treating renal stones in children is safe and effective as it is associated with a relatively low rate of significant complications and achieves a high stone-free rate.

A clinically useful characterization of the cognitive aging process requires the development of valid and robust behavioral tests, with an emphasis on explaining and understanding typical inter-individual variability in cognition. Here, using a dataset that includes behavioral scores collected with the National Institute of Health Toolbox Cognition Battery (NIHTB-CB) and other auxiliary tests, we examined (1) the differences between young and old adults across different cognitive domains, (2) the strength of across-subject correlations in behavioral test scores, (3) the consistency of low-dimensional behavioral representations across age using factor analysis, and (4) the accuracy of behavioral scores in predicting participants' age. Our results revealed that (1) elderly females had better verbal episodic memory scores than elderly males, (2) across-subject correlations between behavioral tests varied with age group, (3) although a three-factor model explained the behavioral data in both age groups, some tasks loaded to different factors between the two groups, and (4) age-performance relationship (i.e. a regression model linking age to cognitive scores) in one group cannot be extrapolated to predict age in the other group, indicating an inconsistency in age-performance relationships across groups. These findings suggest that executive function tests might tap into different cognitive processes in different age groups, which might ultimately suggest that a statistically significant between-group difference in test performance might not always reflect differences in the same underlying cognitive processes. Overall, this study calls for more caution when interpreting age-related differences and similarities between age groups with different cognitive abilities even when the same tests are used.

The Alberta Stroke Program Early Computed Tomography Score (ASPECTS) is a valuable and easy-to-use method for assessing acute ischemic stroke. It aids in identifying suitable candidates for thrombolytic therapies and evaluating treatment effectiveness. However, ASPECTS evaluation primarily relies on visual observation in current clinical practice, lacking a common standardized space. Additionally, different doctors may have varying clinical experiences, leading to a poor inter-reader agreement and potential errors in the final ASPECTS scoring. To address these issues and fill in the absence of a publicly available ASPECTS atlas, this work constructs age-specific Chinese ASPECTS atlases based on non-contrast computed tomography images of 281 healthy subjects across different age groups. Images of different age groups are warped into respective common averaged spaces, where the average intensity atlases are computed. More importantly, 10 ASPECTS regions can be obtained during this process. We develop an automated ASPECTS region mapping pipeline and collect an independent dataset to validate our atlas. The results prove that the age-specific ASPECTS atlas is of great promise in clinical availability. [ABSTRACT FROM AUTHOR]

The aim of this research was to examine the effect of teach-back method-based training provided to reproductive-age women to protect them from sexually transmitted diseases (STDs) on their protective behaviors. Sexually transmitted diseases cause significant health problems for many women every year. The transmission of sexually transmitted diseases can be prevented through health education, which is among the preventive health services. Nurses are the leading health educators. Nurses should learn new education systems and models and use them in their practice. This study has a randomized controlled design. The teach-back method and face-to-face training were provided to women of reproductive age experimentally for protection from sexually transmitted diseases. In this research, the teach-back method in which there were 42 participants in each group, an identifying information form for women in three groups who were provided face-to-face training and not trained, the Behavioral Scale for Protection from Sexually Transmitted Diseases were applied pre-training, fifteen days and three months after the training. Participants' socio-demographic data in the intervention and control groups were compared. The mean age of the teach-back group had been 30.64 ± 5.73, the average age of the face-to-face group had been 29.83 ± 5.49, and the mean age of the non-trained group had been 28.16 ± 5.09. These groups had displayed similar characteristics. The mean score of the Behavioral Scale for Protection from Sexually Transmitted Diseases was found to be 75.57 ± 12.78 pre-training, 82.54 ± 9.59 fifteen days after the training and 81.85 ± 9.28 three months after the training in women who were trained with the teach-back method; 76.92 ± 10.03 pre-training, 80.78 ± 8.72 fifteen days after the training and 80.21 ± 8.77 three months after the training in women who received face-to-face training, while it was found in women who did not receive face-to-face training to be 75.73 ± 6.14 pre-training, 75.61 ± 6.01 fifteen days after the training and 75.54 ± 6.09 three months after the training and there was a statistically significant relationship between them (F = 6.736; p < 0.001). As a result of the research, it was found that the training provided to women with the teach-back method had a positive effect on women's behaviors and was more effective than face-to-face training.

We assessed the effect of continuity of care (COC) on the frequency of hospitalization for Ambulatory care-sensitive conditions (ACSCs) to estimate the impact of COC and hearing disability relative to the controls. This retrospective cohort study used claim data of Korean National Health Insurance Service – National Sample Cohort 2.0 DB. We used propensity score matching to determine a control group for the hearing disability group by age, sex, and the Charlson Comorbidity Index. The hearing-impaired group included 720 participants, and the non-disabled control group, consisting of individuals without any form of disability, had 1,423 individuals. We used the frequency of hospitalization for ACSCs during one-year follow-up as the dependent variable for Poisson regression. We measured COC with the Bice–Boxerman Continuity of Care Index (COCI); higher COCI values represent better continuity of care, with COCI values ranging from 0 to 1. Poisson regression showed that disability status modifies the effect of COCI on the incidence of hospitalization. COCI = 1 reduced hospitalizations in people with hearing disabilities (adjusted Incidence Rate Ratio [aIRR]: 0.30, 95% CI: 0.20–0.44) but was not statistically significant for controls. In the COCI = 1 group, the effect of disability was not significant(aIRR: 1.10, 95% CI: 0.83–1.44). Compared to people without disabilities, enhanced COC for people with hearing disabilities was more effective in preventing hospitalizations for ACSCs. [ABSTRACT FROM AUTHOR]

Background: Hepatic manifestations of hemophagocytic lymphohistiocytosis (HLH), an underrecognized primary presentation in pediatric age group, mandate high levels of suspicion for early diagnosis. Aim: This is to study the frequencies of clinical and laboratory hepatic involvement in patients with familial/primary or secondary/acquired HLH in relation to disease reactivation and outcome. Methods: A 6-month retrospective cohort study recruited 35 patients with HLH. Detailed clinical, laboratory, and genetic characteristics of HLH were collected. Hepatic transaminases and synthetic liver functions were collected at presentation, weeks 2 and 8 after starting treatment, and at time of reactivation. Biochemical liver involvement was considered when alanine aminotransferase (ALT) lived three-times more than the upper normal level. Overall (OS) and reactivation free survival were analyzed according to liver involvement. Results: Twenty patients (57%) had genetically confirmed HLH, 12 (34.3%) had MUNC13D mutations, 3 (8.5%) had STXBP2 mutations, and 5 (14.3%) had RAB27A mutations, while 9 (25.7%) had no genetic mutations with 4 of them had secondary HLH. Six patients (17.2%) patients had unknown genetics status. Median (IQR) age of the whole group was 18 months (6–36) with an age range of 2–108 months. Liver enlargement was detected at diagnosis in 29 (82.9%) and at reactivation in 18 (51.4%) patients. Eight (22.86%) patients had biochemical hepatic involvement at presentation with no significant difference in their demographic, initial clinical presentation, survival, or the type of mutant gene according to liver involvement. Conclusion: Variable hepatic biochemical involvement might be the presenting manifestation of HLH at diagnosis and upon reactivation, yet it did not impact disease outcome. [ABSTRACT FROM AUTHOR]

Background: Inflammatory Bowel Disease (IBD) is an early onset condition that affects individuals of all ages. Approximately 15%–25% of patients present before the age of 20 years, with peak onset occurring during adolescence. Aims: To evaluate transition readiness among adolescents diagnosed with IBD and identify barriers to transition. Methods: We conducted a cross-sectional study of patients with IBD aged 12–21 years. Patients were stratified by age into three groups: A (12–14 years), B (14–17 years), and C (17 + years). Patients were asked to complete a questionnaire which assessed patient knowledge in three areas of transition: 'Taking Charge,' 'My Health,' and 'Using Health Care.' Fisher's Exact and Chi-Square tests were used to evaluate the associations between age and transition readiness. Results: A total of 127 participants (68 males and 59 females) with a mean age of 16.14 years were included. Transition readiness increased with age from 60.7% in Group A to 63.2% and 77.9% in Groups B and C, respectively (p < 0.001). Patient confidence and the importance of transition increased with age, with means of 5.51, 6.17, and 6.94 in Groups A, B, and C (p = 0.02). Patient-reported knowledge of their health condition was > 70%, with no statistical differences between the groups (p = 0.65). Patient knowledge regarding 'Using Health Care' increased from 52% in Group A to 79% in Group C (p < 0.001). The greatest barriers to transitioning were carrying health information for Group A (100%) and obtaining provider referrals for Groups B (75%) and C (51%). Conclusion: This study demonstrated that transition readiness increases with age in adolescents with IBD. [ABSTRACT FROM AUTHOR]

Purpose: This study aimed to quantify and evaluate morphology of intervertebral space between neighboring cervical units using radiographic imaging indices, to help spine surgeons when performing anterior cervical discectomy and fusion (ACDF) surgery on the Chinese population. Methods: The background and imaging parameters of the subjects were assessed. Cervical lateral radiographs were employed to measure the intervertebral height (IH), intervertebral height index (IHI), and segmental lordosis (SL). Endplate parameters measurements were conducted on sagittal T2-weighted magnetic resonance imaging (MRI), including endplate sagittal diameter (ESD), and endplate concavity depth (ECD). All individuals were divided into three age groups: individuals aged 20–35 were in group A, individuals aged 36–50 were in group B, and individuals aged over 50 were in group C. A comparison of the variables was conducted among the three groups. Additionally, these radiographic parameters were also compared between males and females. Results: A total of 102 individuals were included in this study. IH was greater at C6/7 than those at other segmental levels (p < 0.001). The largest SL values were found at C6/7, while the least were found at C3/4. The superior ESD (ESDs) and ECD (ECDs) of the intervertebral space were significantly greater than those of the inferior endplates (p < 0.05). The ESD and ECD values were the largest at C6/7, while the least at C3/4. Additionally, age and gender had an influence on several parameters. IH was significantly lower in group A compared to group B (p < 0.05) and group C (p < 0.05) from C3/4 level to C6/7 level. ECDs were lower in group A compared to group B (p < 0.05) and group C (p < 0.05) at each level. IH and ESD in males were generally significantly greater than those in females at all levels (p < 0.05). Conclusion: The current study found that C6/7 had the greatest IH, SL, ESD, and ECD values in asymptomatic Chinese. SL gradually increased from C3/4 to C6/7 levels. IH and ECD were significantly associated with age. Males had greater IH and ESD values than females. These findings provide baseline information for planning for selection of anterior screws and intervertebral implants. [ABSTRACT FROM AUTHOR]

Objective: To investigate the anatomical indexes and anatomical positional indexes of the atlantoaxial synchondroses in normal Chinese Han children aged 1–6 years, and to analyze the changing law of the atlantoaxial cartilage union with the growth and development of age and its influence on the atlantoaxial ossification in children. Methods: A retrospective collection of CT imaging of 160 cases of normal cervical spine in children aged 1 to 6 years old was conducted. The cases were divided into six age groups, with each group representing a one-year age range. Measure the morphological anatomical indicators and anatomical positional indicators of the atlantoaxial synchondroses. Record and statistically analyze the measurements of each indicator. Results: Measurements were taken on various parameters of the atlantoaxial synchondroses. TD, SD, height, area, and perimeter all gradually decreased among the groups. Distance between bilateral atlantal anterolateral synchondroses increased gradually from Group A to Group F, while the angle formed along the long axis in the cross-section showed a decreasing trend. Distance between the axoid dentolateral synchondroses and between the neurocentral synchondroses increased gradually from Group A to Group F, with the angle value in the cross-section showing a gradual decrease, and distance from the odontoid apex increasing from Group A to Group F. Conclusions: The atlantoaxial synchondroses gradually decrease in size with age, and ossification levels increase with age, with faster ossification occurring during a 1–2 years-old period. The anterolateral synchondroses, dentolateral synchondroses, and neurocentral synchondroses all gradually ossify towards the lateral direction with increasing age. [ABSTRACT FROM AUTHOR]

This study reviews the impact of eligibility policies in the early rollout of the COVID-19 vaccine on coverage and probable outcomes, with a focus on New York City. We conducted a retrospective ecological study assessing age 65+, area-level income, vaccination coverage, and COVID-19 mortality rates, using linked Census Bureau data and New York City Health administrative data aggregated at the level of modified zip code tabulation areas (MODZCTA). The population for this study was all individuals in 177 MODZCTA in New York City. Population data were obtained from Census Bureau and New York City Health administrative data. The total mortality rate was examined through an ordinary least squares (OLS) regression model, using area-level wealth, the proportion of the population aged 65 and above, and the vaccination rate among this age group as predictors. Low-income areas with high proportions of older people demonstrated lower coverage rates (mean vaccination rate 52.8%; maximum coverage 67.9%) than wealthier areas (mean vaccination rate 74.6%; maximum coverage 99% in the wealthiest quintile) in the first 3 months of vaccine rollout and higher mortality over the year. Despite vaccine shortages, many younger people accessed vaccines ahead of schedule, particularly in high-income areas (mean coverage rate 60% among those 45–64 years in the wealthiest quintile). A vaccine program that prioritized those at greatest risk of COVID-19-associated morbidity and mortality would have prevented more deaths than the strategy that was implemented. When rolling out a new vaccine, policymakers must account for local contexts and conditions of high-risk population groups. If New York had focused limited vaccine supply on low-income areas with high proportions of residents 65 or older, overall mortality might have been lower. [ABSTRACT FROM AUTHOR]

Dacryocystorhinostomy (DCR) stands as an essential surgical procedure for addressing the persistent challenge of dacryocystitis—a condition marked by inflammation of the lacrimal sac due to nasolacrimal duct obstruction. A hospital-based retrospective study was conducted in a tertiary care hospital, spanning the years 2018 to 2023, involving 34 patients who underwent Endoscopic Dacryocystorhinostomy. The study involved the examination of their clinical presentations, surgical techniques employed, and resulting outcomes along with causes of failure. Our study included 34 patients who had presented with persistent watering of eyes. The maximum number of cases was in the age group of 46–60 years (38%), with a minimum age of 7 years and a maximum age of 68 years. Among those 34 patients, 5 underwent a revision DCR. Fifteen patients underwent stenting. Thirteen of the fifteen patients, who underwent stenting came for regular postoperative follow up and stent removal was done 6 to 8 weeks later. The two patients who were lost to follow-up presented after 4 years of their initial surgery with persistent symptoms. The success rate of endoscopic DCR was 94% in our study. Endoscopic Dacryocystorhinostomy has emerged as a practical solution for addressing nasolacrimal duct obstruction. Despite numerous surgical modifications documented over time, the endoscopic DCR technique consistently demonstrates excellent outcomes with minimal patient morbidity. This study underscores the significance of thorough preoperative assessment, making informed decisions regarding stenting during both the preoperative and intraoperative period, employing proper surgical techniques, and recognizing the importance of regular post-operative follow-up.

This study was undertaken for study of anatomical results and hearing improvement in various types of tympanoplasty using conchal cartilage. A total of 100 patients were taken for this study the patients belongs to varying age groups from 1st to 6th decade of life.Maximum patients were in between age group 21 to 30 years, 37 (37%) patients and minimum 02(2%) between age group 51 to 60 years. Out of these an overall average gain of 13.33dB in PTA(pure tone audiometry) as well as ABG(air bone gap) was seen however an overall average deficit of 32.15dB in PTA as well as 16.43dB in ABG was seen. The tympanoplasty performed were with or without any additional surgeries of mastoid like Cortical, Atticotomy, CWW, MRM.The pre and post ABG was mainstay for each of our case and final anatomical result of graft uptake. Key points: Type I Tympanoplasty had an average deficit of 15.26 in ABG. Type II Tympanoplasty had an average deficit of 12.75 dB in ABG. Type III Tympanoplasty had an average deficit of 19.42 dB in ABG. Type IV Tympanoplasty had an average deficit of 24 dB in ABG. An overall average gain of 13.33 dB in ABG was seen. An overall average deficit of 32.15 dB in PTA as well as 16.43 dB in ABG was seen. The main aim of our study is to counsel the patient that there will not be complete improvement of hearing if we have done type III and type IV tympanoplasty in advanced disease. This is also of importance for medicolegal purpose. [ABSTRACT FROM AUTHOR]

Epistaxis is the most common emergency in otorhinolaryngology affecting up to 60% of the population in their lifetime. There are various local and systemic cause and includes both medical and surgical management. This study has been undertaken to study various etiopathogenesis and management of epistaxis. This is a prospective hospital-based study conducted on 100 patients of all age groups and both genders presenting with epistaxis to the Department of Otorhinolaryngology both on outpatient and inpatient basis. A detailed history taking with clinical examination is done. Data is entered in a structured performa, master chart prepared and is subjected to statistical analysis by SPSS software version 23. The most common age group was first decade (26%) followed by fourth decade (15%) with male (71%) predominance. Anterior epistaxis (87%) and bilateral nasal cavity involvement (65%) was predominantly seen. Most common causes for epistaxis are trauma (20%) followed by nasal infections (18%) and hypertension (17%). Majority of the patients underwent medical line of treatment (80%) followed by anterior nasal packing (12%), surgical intervention (7%), posterior nasal packing (1%). Epistaxis needs immediate restoration of hemodynamic parameters with first aid, airway assessment and control of bleeding. Majority of the cases were managed conservatively which is safe and cost effective method. Patients should be advised to avoid strenuous activity, nose picking and vigorous nose blowing. Severe recurrent epistaxis needed invasive interventions like nasal packing and blood transfusion. [ABSTRACT FROM AUTHOR]

Endoscopic middle ear surgery can be utilized to visualize and excise retraction pockets without the need for extensive bone work and removal of lateral bone. To evaluate the role of endoscope in the management of squamosal type of chronic otitis media. A total of 25 adults subjects (male = 12, female = 13) in the age group of 18–55 years suffering with chronic otitis media were operated by transcanal endoscopic approach. High resolution computed tomography of temporal bone was done to help identify the anatomy and underlying extent of disease. All patients were operated by transcanal endoscopic technique. The study concluded that the endoscope gives a better visualization of the middle ear and its hidden areas. The extensive bone work and associated cavity related problems can be avoided and normal anatomy can be preserved with the help of endoscopic ear surgery. [ABSTRACT FROM AUTHOR]

This study was undertaken to assess the outcome of canal wall window tympanomastoidectomy in chronic suppurative otitis media in a tertiary care centre of central India. A total of 50 patients were taken for this study in which the youngest patient was 13-year-old male and oldest 55-year female. Maximum patients were in between age group 10 to 20 years, 20 (40%) patients and minimum 03 (6%) between age group 51 to 60 year. The study mainly emphasized on: To study the clinical profile of the cases of chronic suppurative otitis media, to study the hearing outcome after 3 months of Canal wall window tympanomastoidectomy technique, to study the post-operative condition of ear after 3 months whether dry or wet and to study the post-operative follow up of cases to assess the graft uptake. Average PTA & ABG improvement of different tympanoplasty was also calculated in our study in which Type I tympanoplasty had 12.20dB gain, Type II of 10.50 and Type III of 10.31dB.An overall average improvement in all patients with tympanoplasty was 11.00dB.At the end of the study 100% dry ears were achieved. The technique of canal wall window tympanomastoidectomy involves formation of a window in the outer attic wall to look at the disease extent which was then closed by a snuggly fitting cartilage.It is a novel technique & without compromising the structural integrity in case of a limited disease which is only extending till attic and aditus good anatomical and hearing results could be gained.

Background: Obstructive Sleep Apnea Hypopnea (OSAHS) Syndrome is defined by repetitive episodes of apneas or hypopneas, excessive daytime somnolence; waking up during sleep with gasping, choking, or breath holding; or witnessed reports of apneas, loud snoring, or both. The current gold standard diagnostic test for OSAS is polysomnography. Material and Methods: A total of 30 patients diagnosed with stroke and OSA at tertiary care hospital were included in this study. They underwent clinical evaluation and investigations including polysomnography. They were then subjected to drug induced sleep endoscopy and findings were noted according to VOTE classification. Result: Patients belonged to age groups ranging from 3 to 8 decade of life. Mean BMI was found to be 33.02 (+/-8.37) where 73.33% patients were overweight and obese category. Multilevel obstruction was present in 96.67% of patients Oropharynx was most common site of obstruction in our study. Velum(86.6%) was 2nd most common site of obstruction. This was the most common type of obstruction in our study was multilevel collapse (46.67%) including all 4 sites i.e. velum, oropharynx, tongue base and epiglottis. BMI in this study was found to have insignificant correlation with multi-level severe obstruction (p = 0.306). Conclusion: Obstructive sleep apnoea is a common finding in majority of patients suffering from chronic lifestyle diseases. In our study, we found that DISE is easy to perform, safe and reliable tool for evaluation of OSA with CVA patients as the majority of these patients have multi-level obstruction. The procedure also provides important information about dynamic changes in upper airway during sleep. Multilevel obstruction is the most common obstruction. [ABSTRACT FROM AUTHOR]

Almost all currently licensed disease-modifying therapies (DMTs) for MS treatment require prolonged if not lifelong administration. Yet, as people age, the immune system has increasingly reduced responsiveness, known as immunosenescence. Many MS DMTs reduce the responsiveness of the immune system, increasing the risks for infections and possibly cancers. As people with MS (pwMS) age, it is recognized that inflammatory MS activity declines. Several studies have addressed de-escalation of DMTs for relapsing MS under special circumstances. Here, we review evidence for de-escalating DMTs as a strategy that is particularly relevant to pwMS of older age. Treatment de-escalation can involve various strategies, such as extended or reduced dosing, switching from high-efficacy DMTs having higher risks to moderately effective DMTs with lesser risks, or treatment discontinuation. Studies have suggested that for natalizumab extended dosing maintained clinical efficacy while reducing the risk of PML. Extended interval dosing of ocrelizumab mitigated the decline of Ig levels. Retrospective and observational discontinuation studies demonstrate that age is an essential modifier of drug efficacy. Discontinuation of MS treatment in older patients has been associated with a stable disease course, while younger patients who discontinued treatment were more likely to experience new clinical activity. A recently completed 2-year randomized-controlled discontinuation study in 260 stable pwMS > 55 years found stable clinical multiple sclerosis with only a small increased risk of new MRI activity upon discontinuation. DMT de-escalation or discontinuation in MS patients older than 55 years may be non-inferior to continued treatment with immunosuppressive agents having higher health risks. However, despite several small studies, a definite conclusion about treatment de-escalation in older pwMS will require larger and longer studies. Ideally, comparison of de-escalation versus continuation versus discontinuation of DMTs should be done by prospective randomized-controlled trials enrolling sufficient numbers of subjects to allow comparisons for MS patients of both sexes within age groups, such as 55–59, 60–65, 66–69, etc. Optimally, such studies should be 3 years or longer and should incorporate testing for specific markers of immunosenescence (such as T-cell receptor excision circles) to account for differential aging of individuals.

Background: Epidemiological studies on multisystem atrophy (MSA) are scarce. Our aim has been to analyse 10-year incidence, point prevalence, survival, and the time to diagnosis of MSA in Navarre, a northern Spanish region. Methods: This is a population-based observational retrospective study, from 2012 to 2021, which covered the population of Navarre (followed until 31 December 2021). Data from various sources of health information were reviewed in order to identify all potential diagnoses of MSA, that were validated from medical records. Patients were included if they fulfilled the new Movement Disorder Society criteria. Results: We observed a crude average annual incidence rate (IR) of 0.49/100,000 person-years, with the highest occurring in the age group of 60–69 years. No significant IR differences by sex or subtype were observed. Point prevalence in December 2021 was 2.43/100,000 inhabitants. Joinpoint analysis for global incidence and prevalence experienced stable annual rates during the whole period, showing an upward trend for prevalence without a statistically significant slop. The median age at symptom onset was 65 years (range 47–76). The median time to diagnosis was 36 months, without statistically significant differences between sex, age at diagnosis or subtypes. Median time of survival from clinical onset was 7 years. Age of onset above 70 years and autonomic onset were associated with reduced survival. Conclusions: This is the first population-based epidemiological study on MSA in Spain. It provides detailed incidence and prevalence data for MSA that may be useful for appropriate management of health resources. [ABSTRACT FROM AUTHOR]

Purpose: Amputations are a common surgical procedure resulting from trauma during earthquakes, leading to severe disability. This study aims to investigate surgical outcomes specific to amputations that occurred in Adıyaman after the Kahramanmaraş earthquakes. Methods: This descriptive study included amputees who presented to Adıyaman University Training and Research Hospital. Between March 6, 2024 and March 29, 2024, amputees were contacted by phone and asked the questions in the form. Data analyzed included demographic information, number and level of amputated extremities, phantom limb pain, stump infection, extrication time, time to initiation of rehabilitation, number of revision, and whether a prosthesis was fitted. Results: The study reached 75 amputees. The mean age was 37.9 ± 19.2, and the most frequently amputated age group was adults. Stump infection was observed in 40 amputees (53.3%), phantom limb pain in 47 (62.6%), and revision in 29 (38.7%). The median extrication time was 36 h and initiation of rehabilitation time was 45 days. It was noted that 35 amputees (62.5%) used prostheses. A statistically significant relationship was found between fasciotomy and stump infection (p =.000). Infection was detected in 65% of those who underwent fasciotomy. Conclusion: Earthquake-related amputations most frequently affected the adult age group and primarily involved lower extremity amputations, such as transfemoral and transtibial amputations. Phantom limb pain, need for revision, and infection are common in earthquake-induced amputations. Delayed fasciotomy increases the risk of stump infection. The data obtained in this study will help plan local health services to coordinate amputation care in disasters. [ABSTRACT FROM AUTHOR]

Purpose: To analyse the time-to-surgery of a centre of excellence in hip fractures of the elderly and its influence on inpatient mortality and postoperative complications. Methods: A cross-sectional cohort study was conducted. The sample universe consisted of 4,364 patients admitted to a university clinic in Chía, Colombia during the year 2018 to 2023 with ICD-10 diagnoses corresponding to femur fractures. After eliminating duplicates and application of inclusion and exclusion criteria, the final sample included was 269 patients. Qualitative and quantitative variables were analysed, such as: sex, age, age group, type of fracture, type of surgical procedure, time-to-surgery, time to discharge, inpatient mortality and postoperative complications. Results: The mean time-to-surgery from admission was 70.16 h or 2.92 days (IQR 37–87). Patients were divided into three subgroups of time in which they were taken to surgery: <24 h (11.89%), 24–48 h (33.82%) and > 48 h (54.27%). The overall mortality rate was 1.85% for a total of five deceased patients, two of whom belonged to the 24–48-hour group and three to the > 48 h group. Higher rates of postoperative complications were observed in the > 48-hours group (n: 39, 14.49%), followed by the 24–48-hour group (n: 25, 9.29%) and the < 24-hour group (n: 7, 2.6%). Conclusions: Patients operated for a hip fracture in > 48 h since admission had a slightly higher rate of postoperative complications. No significant difference was observed regarding inpatient mortality when compared to the 24–48-hour group. [ABSTRACT FROM AUTHOR]

The ladybird beetles Cheilomenes sexmaculata and Propylea dissecta serve as effective bio-control agents, preying upon aphid populations and thereby mitigating plant damage. These beetles coexist together and show different reproductive strategies. Previous studies have found prevalent heterospecific mating between C. sexmaculata male and P. dissecta female, documenting the effects of heterospecific male C. sexmaculata on the reproductive output of P. dissecta female. In light of these observations, we conducted an experiment examining the influence of heterospecific male age on the reproductive output of P. dissecta. This study involved three age groups of male: (a) young (10–20 days), (b) middle (30–40 days), and (c) old (50–60 days). These males were introduced into Petri dishes with conspecific mates of P. dissecta. Across all experimental treatments, we examined the impact of three different age cohorts of C. sexmaculata males on the mating and reproductive attributes of P. dissecta. Our findings unveiled that older heterospecific males, which displayed reduced choosiness and heightened activity, engaged in reproductive interference to a greater degree than younger C. sexmaculata males during conspecific P. dissecta mating. Further, post-mating encounters with young heterospecific males led to a reduction in the reproductive output of female P. dissecta. The insights gained from this study hold significant implications for comprehending the feasibility of releasing multiple species of ladybird beetles within the same agricultural field. Such understanding of interspecies interactions and their consequences is vital for optimizing integrated pest management strategies. [ABSTRACT FROM AUTHOR]

Parental age plays a major role in determining the life history attributes of an organism. Variation in parental age can have a big impact on offspring development, body mass and structure of population. To test the hypothesis that the increase in parental age has negative effects on offspring development of next generation, we observed the effect of parental age on the selected population of developmental variants (slow and fast developers) in a ladybird beetle, Propylea dissecta Mulsant (Coleoptera: Coccinellidae). The newly emerged adults were divided into two lines: Slow and Fast developers on the basis of their total developmental durations. Adult body mass, slow-fast emergence, sex-ratio, percentage of immature survival of newly emerged adults was recorded. Total developmental duration increased with the increase in age across generation and more fast developers were found in the offspring of young age groups; however, only slow developers were produced by old age groups. Offspring of older age showed higher immature mortality which supports slow-growth-higher mortality hypothesis. Thus, it can be concluded that young age beetles show better performance in terms of growth and developmental duration in P. dissecta in comparison to middle age and old age groups.

Traumatic brain injury (TBI) is a complex brain problem that causes significant morbidity and mortality among people of all age groups. The complex pathophysiology, varied symptoms, and inadequate treatment further precipitate the problem. Further, TBI produces several psychiatric problems and other related complications in post-TBI survival patients, which are often treated symptomatically or inadequately. Several approaches, including neuroprotective agents targeting several pathways of oxidative stress, neuroinflammation, cytokines, immune system GABA, glutamatergic, microglia, and astrocytes, are being tried by researchers to develop effective treatments or magic bullets to manage the condition effectively. The problem of TBI is therefore treated as a challenge among pharmaceutical scientists or researchers to develop drugs for the effective management of this problem. The goal of the present comprehensive review is to provide an overview of the several pharmacological targets, processes, and cellular pathways that researchers are focusing on, along with an update on their current state.

Purpose: The current investigation aimed to establish preliminary normative data for endoscopic swallow studies (FEES). The investigators collected data for three timing measures (time to whiteout, duration of whiteout, and total swallow time), three swallowing outcomes (safety, efficiency, and number of swallows per bolus), and one physiologic event (glottal response), for both healthy young and older adults using two liquid volumes, one pureed bolus and a solid bolus. Methods: Blinded raters retrospectively analyzed 65 randomly selected, deidentified videos of endoscopic swallowing examinations from a pool of 163 young and older adults with typical swallowing abilities. Timing measures and analysis of airway invasion, amount of residue, number of swallows, and glottal response were obtained. Results: Preliminary means and quartiles were established for healthy adults in two age groups (young and old), for time to whiteout (WO), number of swallows per bolus, glottal response, Yale Residue Rating Scale Scores, Penetration-Aspiration Scale scores, duration of WO, and total swallow duration. Differences were found between the older and younger groups. Conclusion: The current study represents a preliminary attempt to provide quantitative and normative values for FEES. These data represent reference values to which other bolus presentations and populations can be compared. The data represents proof of concept and merits additional investigation.

Purpose: Epistaxis is a common condition that affects about 60% of the population in their lifetime, with 6% needing medical attention. Little is known about the epidemiology and risk factors of epistaxis outside the health care system. This study aimed to investigate the prevalence and risk factors of epistaxis in a rural Danish population using data from the Lolland-Falster Health Study (LOFUS). Methods: We conducted a cross-sectional survey based on data from LOFUS, a household-based, prospective cohort study in the rural provincial area of Lolland-Falster, Denmark. We enrolled 10,065 participants (≥ 50 years) and collected data on demographics, comorbidities, medication, lifestyle factors, and laboratory parameters. Logistic regressions were used to test for correlations between epistaxis and different risk factors. Results: In total 5.3% of the participants had experienced epistaxis within the past 30 days, and 7.9% had sought medical attention for epistaxis at some point in their lives. We identified several factors that were significantly correlated with increased odds of epistaxis, such as male gender, age group 50–59 years, high BMI (> 25), allergy, diabetes, hypertension, atherosclerosis, angina, and anticoagulant treatment. Excellent or good self-reported health was correlated to significantly lower odds of epistaxis. Conclusion: This study provides a comprehensive overview of the prevalence and risk factors of epistaxis outside the health care system. Our study suggests that preventive measures targeting these risk factors may reduce the incidence and severity of epistaxis in this population. [ABSTRACT FROM AUTHOR]

Purpose: This study aimed to investigate the etiology of hearing loss, including genetic variants, in individuals who underwent cochlear implantation (CI) in their teens to thirties. It also sought to analyze post-CI speech performance and identify prognostic factors affecting CI outcomes in this age group. Methods: We conducted a retrospective review of 421 cochlear implant patients at Seoul National University Bundang Hospital, focusing on 63 subjects aged 10–39 years who underwent their first CI by a single surgeon between July 2018 and June 2022. The study included audiologic evaluation, molecular genetic testing, and analysis of speech performance post-CI. Statistical analyses were performed using SPSS 25 and GraphPad Prism 7. Results: Among 63 participants (M:F, 24:39), nine underwent CI in their teens, 24 in their 20 s, and 30 in their 30 s. Most of them (40, 63.5%) had postlingual deafness. The study found that 65.2% (40/63) of subjects received a genetic diagnosis, with DFNB4 being the most common etiology (37.5%, 15/40). Post-CI speech evaluation showed an average sentence score of 80% across all subjects. Factors such as the onset of hearing loss, duration of deafness (DoD), and preoperative Speech Intelligibility Rating (SIR) significantly influenced CI outcomes. Notably, longer DoD was associated with poorer CI outcomes, but this did not affect individuals with postlingual hearing loss as much. Conclusion: The study concludes that in individuals aged 10–39 undergoing CI, the onset of hearing loss and preoperative SIR are critical predictors of postoperative outcomes. CI is recommended for those with postlingual hearing loss in this age group, irrespective of the DoD. The study highlights the importance of genetic factors especially DFNB4 in hearing loss etiology and underscores the value of the relatively easy-to-evaluate factor, preoperative SIR in predicting CI outcomes.

Limited information exists on age and racial disparities in sleep duration and mortality in the United States (US) population. This study compared the association between mortality and sleep duration within distinct races and age groups in the US. This study used data on 26,915 US citizens (≥ 18 years) from the 2004 wave of the National Health Interview Survey, linked to the National Death Index prospective mortality through 2019. Cox proportional hazard models were used to obtain hazard ratios (HRs) and 95% confidence intervals (CIs) for mortality by sleep duration, race (Whites, Black/African Americans, and Others (AIAN, Asian, and Native Hawaiian or other Pacific Islander)), and age (< 40, 40–60, and ≥ 60 years), while controlling for covariates such as sex, education, smoking status, disease history, and other vital factors. Race and age significantly modified the sleep duration-mortality relationship. Compared to other races, White participants exhibited higher mortality risks at all hours except at 5–6 h [HR: 0.993, 95% CI: 0.923–1.069]. Likewise, sleep duration associated mortality risks varied by age. Those at greater risk included < 40 years sleeping for 1–4 h [HR: 2.461, 95% CI: 1.446–4.187], 40–< 60 years sleeping for less than 7 h and more than 8 h, and ≥ 60 years sleeping for 9 h [HR: 1.309, 95% CI: 1.162–1.475] and ≥ 10 h [HR: 1.662, 95% CI: 1.486–1.858]. Age and race were significant effect modifiers in the sleep duration-mortality relationship. Thus, it is important to consider these factors when evaluating mortality risks associated with sleep patterns. [ABSTRACT FROM AUTHOR]

The study aimed to investigate the pattern and trend of Musculoskeletal (MSK) disorders in people aged 5–19 years from 1990 to 2021. The data was sourced from the Global Burden of Disease study 2021. The Age-standardized DALYs rates (ASDR), age-standardized mortality rate (ASMR), age-standardized prevalence rate (ASPR), and age-standardized incidence rate (ASIR) and their corresponding average annual percent change (AAPC) for MSK disorders were evaluated by sex, region, and sociodemographic index (SDI) quintiles. Globally, the ASPR of MSK disorders among children and adolescents increased per 100,000 population from 3048.66 (95% confidence interval [CI]: 2336.68–3887.02) in 1990 to 3105.46 (95% CI: 2421.09–3904.95) in 2021 (AAPC 0.06 [95% CI: 0.05–0.07]). In 2021, individuals aged 15–19 experienced the highest burden compared to those aged 5–9 and 10–14. In 2021, high SDI countries had the highest ASIR, ASPR, ASDR of MSK disorders. The AAPC of ASPR in high SDI countries showed a stark contrast to that in low SDI countries for the same period (AAPC 0.48 vs. AAPC −0.03). From 1990 to 2021, in low SDI and low-middle SDI countries, the increase in DALYs was primarily due to population growth. However, in middle SDI, high-middle, and high SDI countries, the increases were mainly due to epidemiological changes. Globally, patients aged 10–14 experienced better care compared to those in the 5–9 and 15–19 age groups. Specific preventive health measures are needed for females and adolescents aged 15–19 in high SDI countries. [ABSTRACT FROM AUTHOR]

Skin represents the main barrier against the external environment, but also plays a role in human relations, as one of the prime determinants of beauty, resulting in a high consumer demand for skincare-related pharmaceutical products. Given the importance of skin aging in both medical and social spheres, the present research aims to characterize microscopic changes in human skin composition due to intrinsic aging (as opposed to aging influenced by external factors) via histological analysis of a photoprotected body region. Samples from 25 autopsies were taken from the periumbilical area and classified into four age groups: group 1 (0–12 years), group 2 (13–25 years), group 3 (26–54 years), and group 4 (≥ 55 years). Different traditional histological (hematoxylin–eosin, Masson's trichrome, orcein, toluidine, Alcian blue, and Feulgen reaction) and immunohistochemical (CK20, CD1a, Ki67, and CD31) stains were performed. A total of 1879 images photographed with a Leica DM3000 optical microscope were morphometrically analyzed using Image ProPlus 7.0 for further statistical analysis with GraphPad 9.0. Our results showed a reduction in epidermis thickness, interdigitation and mitotic indexes, while melanocyte count was raised. Papillary but not reticular dermis showed increased thickness with aging. Specifically, in the papillary layer mast cells and glycosaminoglycans were expanded, whereas the reticular dermis displayed a diminution in glycosaminoglycans and elastic fibers. Moreover, total cellularity and vascularization of both dermises were diminished with aging. This morphometric analysis of photoprotected areas reveals that intrinsic aging significantly influences human skin composition. This study paves the way for further research into the molecular basis underpinning these alterations, and into potential antiaging strategies. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of the study was to assess and compare the masticatory performance in children receiving preformed metal crown by Hall technique and conventional technique. Methods: Children having teeth indicated for restorative/endodontic therapy and belonging to the age group of six to ten years were invited to participate in the study. Eighteen children received preformed metal crowns (PMCs) by Hall technique. Meanwhile, nineteen children received preformed metal crowns by the conventional technique. Their masticatory performance (MP) was assessed at T0 (pre-intervention), T1 (day 1 post-intervention), T2 (1 week), T3 (2 weeks), T4 (1 month) and T5 (3 months) using Hue-check Gum® (University of Bern, Switzerland). The chewing gum samples were scanned within 24 h of their collection and processed in the ViewGum Software©. The software calculated the hue value (VOH) which indicated the masticatory performance of the individual. A questionnaire was given to the parents at T4 and T5 to assess any discomfort or pain associated with PMCs placed in both groups. Results: The evaluation of masticatory performance using the two-color chewing method revealed reduction in MP on day 1 post-intervention (p < 0.001) for both groups. However, the MP values recorded at T5 were comparable to the baseline values at T0 (p = 0.009). No significant discomfort or pain was reported in both groups. Conclusion: The findings of the current clinical study indicate that placement of PMCs by both conventional and Hall technique in children deteriorates their MP which equilibrates within 1 month.

Purpose: Little is known about colorectal cancer screening in 9/11 World Trade Center (WTC)-exposed populations. We utilized survey data from the WTC Health Registry (WTCHR) to examine associations between enrollees' characteristics and colorectal cancer (CRC) screening. Methods: We studied 22,061 enrollees aged 50–75 who completed the WTCHR follow-up survey in 2015–2016. Those with a history of CRC were excluded. Screening was defined as a self-reported, routine colonoscopy or sigmoidoscopy during the 12-month period prior to the survey. Multivariable log binomial regression identified factors associated with screening in the 12 months preceding the survey. We also stratified by age group. Results: Of 22,061 enrollees, 23% were screened, with largely similar rates across age groups. Higher screening percentages were seen in selected groups including non-Hispanic Black enrollees (26.4%), males (24.3%), those married/living with a partner (24.1%), those with a higher household income (≥ $150 k, 25.4%), those who received services from the WTC Health Program (25.6%), and those with greater perceived social support (24.4%). On multivariable analyses, non-Hispanic Black enrollees [adjusted relative risk (aRR) = 1.30, 95% confidence interval (CI) 1.19–1.42] were significantly more likely to report screening, even after stratifying by age group. Hispanic enrollees, those with a higher household income, those with increased perceived social support, and those with diagnosed medical conditions under 70 years old were also associated with screening. Conclusion: We found that non-Hispanic Black compared with non-Hispanic White enrollees were more likely to obtain screening for CRC. Continued efforts to promote health and wellness of WTC-exposed population is essential. [ABSTRACT FROM AUTHOR]

Understanding urban vibrancy has been considered crucial to promoting human activities and interactions in public open spaces. Recent advancements in urban big data have facilitated the potential to understand and measure vibrancy patterns throughout cities. While streets are considered the center stage of human activity, previous studies have often overlooked their multifaceted nature and their association with urban vibrancy. In this study, we incorporate multi-source big data and combine a set of features that comprehensively describe the scale, function, and topology of street segments in two Seoul districts: Jung-gu and Gangnam-gu. Using these features, we employ a machine learning clustering technique to classify them into five distinct typologies. Then, with street-level aggregated mobile phone tracking data, we investigate whether street typology characteristics are associated with urban vibrancy with respect to age groups, time of day, and day types (weekends/weekdays). The results show varying relationships between street characteristics with age-, time- and day-vibrancy measures by the identified street typology. Further, we contrast the results of the two districts to evaluate urban vibrancy differences in organic and planned urban layouts. This study enables a more nuanced understanding of urban streets to better comprehend their impact on people's use of street space. The derived novel insights could assist planners and designers to better pinpoint street management solutions for different age- and time-dependent needs based on the complexities in urban vibrancy dynamics.

Purpose: There is a tendency to use data generated for adults in the management of pediatric Differentiated Thyroid Carcinoma, neglecting the clinical peculiarities of this condition in childhood. This study aimed to assess and compare the clinical-epidemiological characteristics and their significance in the evolution of thyroid carcinoma diagnosed in childhood across different age groups. Methods: Seventy-seven patients diagnosed with Differentiated Thyroid Carcinoma (DTC) up to 21 years old were selected and divided into different age groups: up to 10 years, 11 to 18 years, and 19 to 21 years old. Clinical-epidemiological data and their influence in the disease progression were analyzed and compared across age groups. Results: Patients diagnosed below 10 years of age were associated with tumors showing extrathyroidal extension, metastasis in regional lymph nodes, higher levels of stimulated thyroglobulin in the diagnostic iodine-131 whole-body scan (WBS), and under TSH suppression in the last assessment. Additionally, pulmonary metastasis were associated in both diagnostic and post-radioiodine dose WBSs in these younger patients. Analysis of findings in the post-radioiodine therapy WBS revealed significant differences between all age groups (p = 0.0029). The time of diagnosis was identified as a factor associated with an excellent response in subgroups up to 18 years and up to 21 years. No factors associated with dynamic responses over the 1st, 3rd and 5th years of follow-up and the persistence/recurrence of the disease were identified in the subgroup up to 18 years. In the subgroup up to 21 years, having an incomplete structural response in the 3rd year of follow-up increased the chances of recurrent or persistent response by 5.5 times, and by 32.6 times if found in the 5th year of follow-up. Conclusions: Younger patients exhibited more aggressive tumor characteristics and underwent more rigorous treatment. However, treatment response and disease status in the last assessment, whether free or recurrent/persistence, were similar when comparing the age groups of 11 to 18 and 19 to 21 years. Nonetheless, responses obtained in the 3rd and 5th years post-treatment emerged as factors associated with the persistence/recurrence of the disease in the last assessment in the age group up to 21 years but not in patients diagnosed up to 18 years, a relevant distinction considering the tumor behavior in defining the pediatric age range in thyroid cancer.
