The role of preterm birth in stress-induced sodium excretion in young adults.

Early-life programming due to prematurity and very low birth weight (VLBW, <1500 g) is believed to contribute to development of hypertension, but the mechanisms remain unclear. Experimental data suggest that altered pressure natriuresis (increased renal perfusion pressure promoting sodium excretion) may be a contributing mechanism. We hypothesize that young adults born preterm will have a blunted pressure natriuresis response to mental stress compared with those born term. In this prospective cohort study of 190 individuals aged 18-23 years, 156 born preterm with VLBW and 34 controls born term with birth weight at least 2500 g, we measured urine sodium/creatinine before and after a mental stress test and continuous blood pressure before and during the stress test. Participants were stratified into groups by the trajectory at which mean arterial pressure (MAP) increased following the test. The group with the lowest MAP trajectory was the reference group. We used generalized linear models to assess poststress urine sodium/creatinine relative to the change in MAP trajectory and assessed the difference between groups by preterm birth status. Participants' mean age was 19.8 years and 57% were women. Change in urine sodium/creatinine per unit increase in MAP when comparing middle trajectory group against the reference group was greater in those born preterm [β 5.4%, 95% confidence interval (95% CI) -11.4 to 5.3] than those born term (β 38.5%, 95% CI -0.04 to 92.0), interaction term P = 0.002. We observed that, as blood pressure increased following mental stress, young adults born preterm exhibited decreased sodium excretion relative to term-born individuals.

Influence of advertisement on consumers’ buying behavior: A case study of FMCG products

The primary objective of the current study is to examine how advertising impacts the consumer behavior of University students (N = 200). This study aims to delve into the influence of advertising on attitudes related to purchasing behavior. A questionnaire was developed to assess the effect of advertising, and the sample data were gathered from college/University students aged between 20 and 30. Specifically, eight fast-moving consumer goods (FMCG) brands, namely Lux, Pears, Dettol, Dove, Head &amp; Shoulders, L'Oreal Paris, Dove and Tresemme, were considered in the analysis. The data collection process involved evaluating the correlations between these brands and their respective advertisements. The analysis encompassed the utilization of mean, standard deviation, frequency, and percentage, which were then presented in tabular form. The findings unveiled that advertisements play a pivotal role in steering preferences and choices, significantly influencing consumer buying behavior. The model employed in this study appeared to have a more pronounced impact on consumers compared to conventional modes of advertising. Additionally, the results indicated that consumers perceive advertisements as a credible source of information in contrast to other opinions, such as those from friends, neighbors, or reference groups. The study demonstrated that advertisements wield a substantial influence across diverse income groups, regardless of the economic bracket. Interestingly, the study found that the costliness of products and the frequency of advertisement repetition did not significantly alter consumer buying behavior. Among the brands considered, DOVE emerged as the most preferred, followed by PEARS. Notably, more consumers were affected by Dove and Tresemme's advertisement than by Head &amp; Shoulders. Due to Head &amp; Shoulder’s competitive pricing, users favor it over other shampoo brands. The flash of advertising on the big screen drew attention to it and had an impact on consumers.

A healthy habitual score for dietary intake is associated with primary dysmenorrhea among adolescent school girls

Background: Primary dysmenorrhea is one of the most common gynecological complaints among adolescent and young females in their reproductive age that affects their daily activities and social life. Nutritional habits are considered as risk factor for primary dysmenorrhea. ‘Thus the aim of our study was to assess the relation between healthy habits score for dietary intake and prevalence of primary dysmenorrhea. Methods: The present study was conducted on 432 adolescent school girls (218 girls with nil to mild dysmenorrhea and 214 girls with moderate to severe dysmenorrhea). Healthy habitual scores (HHS) was calculated from 5 modifiable dietary intake habits considering high risk habit as ‘0’ and low risk habit as ‘1’ giving a composite score ranging from 0 to 5. We classified the healthy life style score into three category: 0-2 as low; 3 as medium and 4-5 as high. Correlation between HHS and its components with incident of primary dysmenorrhea were evaluated. HHS and risk of primary dysmenorrhea were evaluated using logistic regression analysis. The significance level of the all the tests were considered at a level of 0.05. Results: Significant correlation was obtained between incident of primary dysmenorrhea and all tested habits. Magnitude of correlation was higher for HHS than individual habit. Among tested habitual factors sugar intake, skipping breakfast and frequency of junk food intake was positively correlated where as negative correlation was obtained between primary dysmenorrhea and dietary intake of vit-E and calcium. Considering low HHS as reference group odd ratio significantly low in medium and high HHS groups. Thus risk of primary dysmenorrhea was more among adolescent girls those led unhealthy dietary habits like take more sugar, frequently take junk foods and skipping breakfast and take vit-E and calcium below recommended amount. Conclusion: Avoiding of Junk food, skipping breakfast and intaking of vit-E and calcium as per recommended amount and restricting sugar intake is recommended as a healthy dietary habit to minimize the risk of primary dysmenorrhea.

Impact of childhood traumatic brain injury on fitness for service class, length of service period, and cognitive performance during military service in Finland from 1998 to 2018: A retrospective register-based nationwide cohort study.

Traumatic brain injury (TBI) can cause neuronal damage and cerebrovascular dysfunction, leading to acute brain dysfunction and considerable physical and mental impairment long after initial injury. Our goal was to assess the impact of pediatric TBI (pTBI) on military service, completed by 65-70% of men in Finland. We conducted a retrospective register-based nationwide cohort study. All patients aged 0 to 17 years at the time of TBI, between 1998 and 2018, were included. Operatively and conservatively treated patients with pTBI were analyzed separately. The reference group was comprised of individuals with upper and lower extremity fractures. Information on length of service time, service completion, fitness for service class, and cognitive performance in a basic cognitive test (b-test) was gathered from the Finnish Military Records for both groups. Linear and logistic regression with 95% CI were used in comparisons. Our study group comprised 12 281 patients with pTBI and 20 338 reference group patients who participated in conscription. A total of 8 507 (66.5%) men in the pTBI group and 14 953 (71.2%) men in the reference group completed military service during the follow-up period. Men in the reference group were more likely to complete military service (OR 1.26, CI 1.18-1.34). A total of 31 (23.3%) men with operatively treated pTBI completed the military service. Men with conservatively treated pTBI had a much higher service rate (OR 7.20, CI 4.73-11.1). In the pTBI group, men (OR 1.26, CI 1.18-1.34) and women (OR 2.05, CI 1.27-3.36) were more likely to interrupt military service than the reference group. The PTBI group scored 0.15 points (CI 0.10-0.20) less than the reference group in cognitive b-test. PTBI groups had slightly shorter military service periods and higher interruption rate than our reference-group. There were only minor differences between groups in cognitive b-test.

Musculoskeletal System and Gait Characteristics in Patients with Osteogenesis imperfecta.

The aim of the study was to assess the muscoloskeletal system and spatiotemporal gait parameters of patients in three types of osteogenesis imperfecta. Retrospective observational study. The Department of Rehabilitation, Children's Memorial Health Institute in Warsaw, Poland. This study investigated individuals with various types of osteogenesis imperfecta: 33 with osteogenesis imperfecta I (aged 13.9), 16 with osteogenesis imperfecta III (aged 10.4), and 14 with osteogenesis imperfecta IV (aged, 15.8), as well as a reference group of 400 healthy individuals. The musculoskeletal assessment included: medical record review, clinical evaluation, functional tests, long bone deformity assessment via clinical and X-ray examination, and objective gait analysis with the Vicon Motion Systems (Ltd, Oxford, UK). The study revealed notable differences in clinical presentation, deformities within the musculoskeletal system, gait parameters across the various types of osteogenesis imperfecta (p < 0.001). The most affected gait parameters were: cadence, gait speed and step length. The greatest deformities of lower limbs and spine were presented in patients with osteogenesis imperfecta type III. These findings are significant for understanding gait abnormalities in osteogenesis imperfecta patients and designing customized physiotherapy programs to help them participate fully in daily life. Improvement of muscle strength is one of the key for easier engagement in activities like walking or stair-climbing.

Relative bioavailability, immunogenicity, and safety of two adalimumab-adbm formulations in healthy volunteers: a double-blind, randomized, single-dose, parallel-arm Phase I trial (VOLTAIRE-HCLF)

ABSTRACT Objective VOLTAIRE-HCLF compared the relative bioavailability of citrate-free high-concentration and reference formulations of the biosimilar adalimumab-adbm (Cyltezo®), including pharmacokinetic (PK) profiles, immunogenicity, and safety profiles in healthy volunteers. Methods Healthy volunteers (N = 200) aged 18–55 years and with body mass index of 18.5–29.9 kg/m2 and no prior exposure to adalimumab were randomized in a 1:1 ratio to receive a single subcutaneous injection of either adalimumab-adbm 40 mg/0.4 mL (high-concentration formulation) or 40 mg/0.8 mL (reference formulation). Participants completed 13 follow-up visits over 57 days, followed by a safety follow-up period of up to 70 days. Results The main PK parameters were similar for the high-concentration and reference groups. For all primary endpoints, the geometric mean ratios and 90% confidence intervals of AUC0–1344, AUC0–∞, and Cmax for both groups were entirely within the standard 80–125% bioequivalence acceptance range at 101.88% (93.31–111.23%), 105.38% (95.06–116.81%), and 91.29% (84.38–98.76%), respectively. There were no differences in the proportion of anti-drug antibody-positive participants or in the distribution of anti-drug antibody titers between the two formulations at any time point after drug dosing. Participants who were given the high-concentration formulation of adalimumab-adbm experienced a lower incidence of adverse events and local reactions than those who were given the reference formulation. Conclusions Overall, the high-concentration and reference adalimumab-adbm formulations had highly similar PK and immunogenicity profiles and were safe and well tolerated. Clinical trial registration NCT05203289

Pre-pregnancy body mass index and low birthweight: Secondary data analysis using health insurance claims data in Japan.

For women, being underweight increases their susceptibility to osteoporosis, anemia, and other conditions and affects the weight of their infants and the well-being of future generations. This study examined the association between low pre-pregnancy body mass index (BMI) and low birthweight using health insurance claims data and health checkup data, including weight measurements. We used health insurance claims data and health checkup data (JMDC, Tokyo, Japan) of women and their newborns in Japan between 2006 and 2020. We used checkup data, which included more accurate weight measurements and blood test-based diagnoses of anemia and hyperlipidemia compared to self-reported data. Maternal pre-pregnancy BMI was compared across three groups: underweight (BMI <18.5 kg/m2), normal weight (BMI 18.5-24.9 kg/m2), and overweight (BMI ≥25.0 kg/m2). The primary outcome was low birthweight (<2500 g), and secondary outcome was preterm childbirth. Logistic regression analyses were conducted to compare outcomes in the three groups by BMI. The underweight BMI group was considered as the reference group. A subgroup analysis was performed by maternal age. In total, 16 363 mothers (underweight, 3418 [21%], normal weight, 11 493 [70%], and overweight, 1452 [8.9%]) were included. The risk of primary outcome (low birthweight) was significantly lower in the normal weight group than in the underweight group (4.6% vs. 5.7%; adjusted odds ratio 0.78 [95% confidence interval: 0.65-0.96]). In the subgroup analyses, no significant differences were noted in the incidences of low birthweight and preterm childbirth between maternal age groups. Pre-pregnancy BMI was associated with an increased risk of delivering low-birthweight infant. Awareness about the importance of women's pre-pregnancy health and appropriate BMI may reduce the incidence of low birthweight.

Associations of perfluoroalkyl substances with metabolic-associated fatty liver disease and non-alcoholic fatty liver disease: NHANES 2017-2018.

This study investigated the potential effects of perfluoroalkyl substance (PFAS) in serum on MAFLD, NAFLD, and liver fibrosis. Our sample included 696 participants (≥ 18years) from the 2017-2018 NHANES study with available serum PFASs, covariates, and outcomes. Using the first quartile of PFAS as the reference group, we used weighted binary logistic regression and multiple ordered logistic regression used to analyze the relationship between PFAS and MAFLD, NAFLD, and liver fibrosis and multiple ordinal logistic regression to investigate the relationship between PFAS and MAFLD, NAFLD, and liver fibrosis and calculated the odds ratio (OR) and 95% confidence interval for each chemical. Finally, stratified analysis and sensitivity analysis were performed according to gender, age, BMI, and serum cotinine concentration. A total of 696 study subjects were included, including 212 NAFLD patients (weighted 27.03%) and 253 MAFLD patients (weighted 32.65%). The quartile 2 of serum PFOA was positively correlated with MAFLD and NAFLD (MAFLD, OR 2.29, 95% CI 1.05-4.98; NAFLD, OR 2.37, 95% CI 1.03-5.47). PFAS were not significantly associated with liver fibrosis after adjusting for potential confounders in MAFLD and NAFLD. Stratified analysis showed that PFOA was strongly associated with MAFLD, NAFLD, and liver fibrosis in males and obese subjects. In women over 60years old, PFHxS was also correlated with MAFLD, NAFLD, and liver fibrosis. The serum PFOA was positively associated with MAFLD and NAFLD in US adults. After stratified analysis, the serum PFHxS was correlated with MFALD, NAFLD, and liver fibrosis.

Automatic extraction of facial median sagittal plane for patients with asymmetry based on the EDMA alignment algorithm.

We aimed to establish a novel method for automatically constructing three-dimensional (3D) median sagittal plane (MSP) for mandibular deviation patients, which can increase the efficiency of aesthetic evaluating treatment progress. We developed a Euclidean weighted Procrustes analysis (EWPA) algorithm for extracting 3D facial MSP based on the Euclidean distance matrix analysis, automatically assigning weight to facial anatomical landmarks. Forty patients with mandibular deviation were recruited, and the Procrustes analysis (PA) algorithm based on the original mirror alignment and EWPA algorithm developed in this study were used to construct the MSP of each facial model of the patient as experimental groups 1 and 2, respectively. The expert-defined regional iterative closest point algorithm was used to construct the MSP as the reference group. The angle errors of the two experimental groups were compared to those of the reference group to evaluate their clinical suitability. The angle errors of the MSP constructed by the two EWPA and PA algorithms for the 40 patients were 1.39 ± 0.85°, 1.39 ± 0.78°, and 1.91 ± 0.80°, respectively. The two EWPA algorithms performed best in patients with moderate facial asymmetry, and in patients with severe facial asymmetry, the angle error was below 2°, which was a significant improvement over the PA algorithm. The clinical application of the EWPA algorithm based on 3D facial morphological analysis for constructing a 3D facial MSP for patients with mandibular deviated facial asymmetry deformity showed a significant improvement over the conventional PA algorithm and achieved the effect of a dental clinical expert-level diagnostic strategy.

The association between dietary vitamin B1 intake and constipation: a population-based study

BackgroundNumerous researches have indicated a correlation between the intake of dietary micronutrients and the occurrence of constipation. Nevertheless, the correlation between constipation and vitamin B1 remains uninvestigated. The main aim of this research was to examine the association between chronic constipation and the consumption of vitamin B1 in the diet among adult participants of the National Health and Nutrition Examination Survey (NHANES).MethodsThis study used data from the NHANES, a survey on health and nutrition conducted between 2005 and 2010. The respondents’ dietary information was gathered by utilizing the 24-hour dietary records. Various statistical analyses, such as multiple logistic regression, subgroup analysis, and curve-fitting analysis, were employed to investigate the correlation between dietary intake of vitamin B1 and chronic constipation.ResultsIn the trial, there were 10,371 participants, out of which 1,123 individuals (10.8%) were identified as having chronic constipation. Fully adjusted multiple logistic regression analyses showed that increasing dietary intake of vitamin B1 (OR = 0.87, 95% CI: 0.77-0.99) was significantly associated with a reduced risk of constipation. Following adjustment for multiple variables in Model 3, the odds ratio (OR) and 95% confidence interval (CI) for the third tertile, in comparison to the first tertile (reference group), was 0.80 (0.65, 0.99). In addition, subgroup analyses and interaction tests showed a significant inverse association between vitamin B1 intake and the prevalence of constipation, especially among men, non-hypertensive, and non-diabetic individuals (all P-values less than 0.05).ConclusionThis research uncovered an inverse correlation between the consumption of vitamin B1 in the diet and the occurrence of chronic constipation. One potential explanation for this phenomenon is that the consumption of vitamin B1 in one’s diet is linked to the softening of stools and an augmented occurrence of colonic peristalsis. Additional extensive prospective research is required to thoroughly examine the significance of thiamine in long-term constipation.

Dutch cardio-oncology cohort: Incident cardiovascular disease predisposes to a higher cancer mortality rate.

Cardiovascular disease (CVD) and cancer are the two leading causes of death worldwide. Given their high prevalence, it is important to understand the disease burden of cancer mortality in CVD patients. We aimed to evaluate whether patients with incident CVD have a higher risk of malignancy-related mortality, compared to the general population without CVD. We performed a national population-based cohort study selecting patients with incident CVD in the Netherlands between 01 April 2000 and 31 December 2005. A reference cohort was selected from the Dutch population using age, sex and ethnicity. Mortality follow-up data were evaluated after data linkage of national registries from Statistics Netherlands until 31 December 2020. A total of 2,240,879 individuals were selected with a mean follow-up of 12 years (range 0.4-21.0), of which 738,666 patients with incident CVD with a mean age of 71 ± 15 years. Malignancy mortality per 1000 person years was 84 for the reference group and 118 for patients with CVD, with the highest rate of 258 in patients with heart failure. Patients with CVD had a higher malignancy mortality risk, compared to the reference group: HR 1.35 (95%CI 1.33-1.36). Highest risks were observed in patients with venous diseases (HR 2.27, 95%CI 2.17-2.36) and peripheral artery disease (HR 1.87, 95%CI 1.84-2.01). Results show that CVD predisposes to a higher cancer mortality rate. Of all CVD subtypes, HF patients have the highest cancer mortality rate and the hazards were highest in patients with venous diseases and peripheral artery disease.

Robotic vs. laparoscopic right hemicolectomy-An analysis of costs

The use of robotic surgical methods for performing right-sided hemicolectomy has been somewhat controversial, primarily due to concerns related to costs. The purpose of this study is to document the initial robotic right hemicolectomies conducted at our institution and to compare them with a laparoscopic reference group. A significant focus of this study is the detailed analysis of the costs associated with both techniques within the German healthcare system.Surgical and cost-related data for 34 cases each for robotic and laparoscopic right-sided hemicolectomy performed at Nürnberg Hospital were compared. This comparison was conducted through a retrospective single-center case-matched analysis. Cost analysis was carried out following the current guidelines provided by the Institute for the Hospital Remuneration System (InEK) of Germany.The average age of the patient cohort was 70 years, with a male patient proportion of 57.4%. Analysis of perioperative parameters indicated similar outcomes for both surgical techniques. Regarding the incidence of complications of Clavien-Dindo stages III-V (8.8% vs. 17.6%; p = 0.48), a positive trend towards robotic surgery was observed. The cost analysis showed nearly identical total costs for the selected cases in both groups (mean €13,423 vs. €13,424; p = 1.00), with the most significant cost difference noted in surgical (operative) costs (€5,779 vs. €3,521; p < 0.01). The lower costs for laparoscopic cases were primarily due to the reduced material costs (mean €2,657 vs. €702; p < 0.05).In conclusion, both surgical approaches are clinically equivalent, with only minor differences in the total case costs.

Associations of single and multiple vitamin exposure with childhood eczema: data from the national health and nutrition examination survey

AimThe association between vitamins and eczema has garnered attention, yet few studies have evaluated the effects of co-exposure to multiple vitamins on this condition. This study aims to assess the association of vitamin mixtures with eczema in children.MethodsThis cross-sectional study analyzed data from 2,244 children aged 6–17 years from the National Health and Nutrition Examination Surveys. Eczema served as the primary outcome. Six serum vitamins, namely, vitamins A, B6, B12, C, D, and E, were the main variables. Weighted multivariate logistic regression was adopted to analyze the association between each serum vitamin and eczema. Odds ratios (OR) with a 95% confidence interval (CI) were calculated. Bayesian kernel machine regression (BKMR) analysis and the quantile g-computation (qgcomp) model were used to evaluate the association of co-exposure to multiple vitamins with eczema.ResultsIn total, 10.83% of children (n = 243) developed eczema. After adjusting for confounding factors, we observed that compared with the reference group (vitamin B12 with second quartile), the OR for eczema was 0.604 (95% CI: 0.373–0.978, P = 0.041) for the first quartile of vitamin B12. Both BKMR analysis and the qgcomp model consistently showed that co-exposure to the six vitamins was positively correlated with the risk of eczema, with vitamin B6 contributing most to the overall effect. In BKMR analyses, we observed an interaction between vitamins B6 and B12 concerning eczema risk.ConclusionCo-exposure to vitamins A, C, B6, B12, D, and E was found to be associated with an increased risk of eczema in children, with vitamin B6 as the greatest positive contributor driving the overall effect.

Rapid Access From Primary Care to a Multidisciplinary Clinic at Tertiary Care Improves Clinical Outcomes for Patients With Diabetic Foot Ulcers: Results From Diabetic Foot in Primary and Tertiary (DEFINITE) Care's Lower Extremity Amputation Prevention Program (LEAPP) Clinic.

Diabetic Foot in Primary and Tertiary (DEFINITE) Care is an inter-institutional, multidisciplinary team (MDT) program for patients with diabetic foot ulcers (DFU) within a healthcare cluster in Singapore. This is one of our subgroup analyses within DEFINITE Care, assessing clinical outcomes of lower extremity amputation prevention program (LEAPP), a multidisciplinary diabetic foot clinic, and non-LEAPP patients within the program. From June 2020 to June 2022, 2798 patients within the DEFINITE cohort completed a minimum of 12-month follow up. Of these patients, 20.6% were managed by LEAPP, whereas 79.4% were non-LEAPP patients. Patients in the LEAPP cohort were older with co-existing metabolic conditions and complications of diabetes. Using non-LEAPP cohort as the reference group and after adjusting for age, gender, ethnicity, comorbidities, and medications, there was a significantly lower risk of death (odds ratio [OR] 0.60, P = .001) and composite major lower extremity amputation (LEA) or death (OR 0.66, P = .002) among LEAPP patients at 1 year with longer mean days from enrollment to minor LEA, major LEA, and death. The adjusted 1-year healthcare utilization outcomes for LEAPP patients demonstrated an increase in inpatient admissions, primary care polyclinic visits, hospital specialist outpatient clinic (SOC) visits and elective day surgery procedures. Despite the increased in inpatients admissions, cumulative hospital length of stay in LEAPP patients were lower. This subgroup analysis has demonstrated that the MDT approach to caring for patients with DFU in tertiary centers not only improves mortality by 40%, but also delayed the incidence of minor LEA, major LEA, and death.

Presurgical pulmonary function tests in the first few days of life in neonates with congenital heart disease, a pilot study.

To compare early pulmonary function tests (PFTs) in neonates with critical congenital heart disease (CHD) compared to a historical reference group. Infants ≥ 37 weeks gestation with critical CHD were studied within the first few days of life, prior to cardiac surgery, and compared to data from a published reference group of healthy term neonates without CHD, studied at the same institution. Passive respiratory resistance (Rrs) and compliance (Crs) were measured with the single breath occlusion technique following specific acceptance criteria. The study was powered for a 30% difference in Rrs. PFTs in 24 infants with CHD were compared to 31 historical reference infants. There was no difference in the Rrs between the groups. The infants with CHD had a significantly decreased Crs (1.02 ± 0.26 mL/cmH2O/kg versus 1.32 ± 0.36; (p < 0.05; mean ± SD)). Further prospective studies are required to quantify early PFTs in infants with CHD of different phenotypes.

Self-Reported Sleep Duration and Bedtime Are Associated with Dementia Risk in Community-Dwelling People Aged 40-74 Years: The Murakami Cohort Study.

Sleep is a potentially modifiable factor associated with dementia, including Alzheimer's disease, but current evidence supporting this is insufficient. This study aimed to determine whether sleep duration and bedtime patterns are associated with the risk of dementia among middle-aged and older people. This cohort study had an eight-year follow-up period. Participants were 13,601 community-dwelling people aged 40-74 years living in Murakami (Niigata, Japan). Data were collected using a self-administered questionnaire. Predictors were self-reported sleep duration and bedtime, and the outcome was newly-diagnosed dementia determined using the long-term care insurance database. Covariates were demographic characteristics, body mass index, smoking, alcohol consumption, total physical activity, insomnia symptoms, disease history, and either bedtime or sleep duration. Cox proportional hazard models were used to calculate hazard ratios (HRs). The mean age of participants at baseline was 59.2 years. Over a mean follow-up period of 8.0 years, 319 cases of dementia were observed. A long self-reported sleep duration relative to the reference sleep duration (7 hours) was associated with increased dementia risk, with the "8 hours" group (adjusted HR = 1.30, 95% CI:0.99-1.73) and "≥9 hours" group (adjusted HR = 1.46, 95% CI:1.00-2.15) having an increased risk (marginally significant) relative to the reference group. Early bedtime was associated with increased dementia risk (adjusted p for trend = 0.0010), with the "21 : 00 or earlier" group (adjusted HR = 1.61, 95% CI:1.14-2.28) having an increased risk relative to the reference ("23 : 00"). A long self-reported sleep duration and early bedtime are both associated with increased dementia risk in middle-aged and older people.

Case Report of Arthroscopic Anatomical Bone Glenoid Augmentation with Subscapularis Tendon Protection with A 24 Months Follow-Up and Literature Review of The Current Concepts of Glenoid Bone Augmentation

Background: The purpose of the present study was to examine the association between non-exercise Cardiorespiratory Fitness (eCRF) and all-cause mortality in cancer patients. Methods and Findings: A total of 2,404 participants from the Aerobics Center Longitudinal Study (622 women and 1,782 men) with a cancer diagnosis were followed for mortality. Non-exercise eCRF was calculated in Metabolic Equivalents (METs) with sex-specific algorithms at baseline. Multivariable Cox regression models were used to examine the association between CRF and risk of all-cause mortality. Hazard ratios and 95% confidence intervals were calculated as an index of strength of the association. More than 96% (2,323) of the 2,404 participants survived, while 81 (3.4%) died. In the multivariable adjusted model, each 1-MET increment was associated with a 17% decreased risk of all-cause mortality. Compared with the reference group, those in the middle CRF group had a 58% lower risk of death and those in the upper CRF group had a 78% lower risk of death than those in the lower CRF group (Ptrend=0.0002). Conclusion: CRF estimated using a non-exercise formula (non-exercise eCRF) is inversely associated with all-cause mortality in cancer patients.

The impact of the world’s first regulatory, multi-setting intervention on sedentary behaviour among children and adolescents (ENERGISE): a natural experiment evaluation

BackgroundRegulatory actions are increasingly used to tackle issues such as excessive alcohol or sugar intake, but such actions to reduce sedentary behaviour remain scarce. World Health Organization (WHO) guidelines on sedentary behaviour call for system-wide policies. The Chinese government introduced the world’s first nation-wide multi-setting regulation on multiple types of sedentary behaviour in children and adolescents in July 2021. This regulation restricts when (and for how long) online gaming businesses can provide access to pupils; the amount of homework teachers can assign to pupils according to their year groups; and when tutoring businesses can provide lessons to pupils. We evaluated the effect of this regulation on sedentary behaviour safeguarding pupils.MethodsWith a natural experiment evaluation design, we used representative surveillance data from 9- to 18-year-old pupils before and after the introduction of the regulation, for longitudinal (n = 7,054, matched individuals, primary analysis) and repeated cross-sectional (n = 99,947, exploratory analysis) analyses. We analysed pre-post differences for self-reported sedentary behaviour outcomes (total sedentary behaviour time, screen viewing time, electronic device use time, homework time, and out-of-campus learning time) using multilevel models, and explored differences by sex, education stage, residency, and baseline weight status.ResultsLongitudinal analyses indicated that pupils had reduced their mean total daily sedentary behaviour time by 13.8% (95% confidence interval [CI]: -15.9 to -11.7%, approximately 46 min) and were 1.20 times as likely to meet international daily screen time recommendations (95% CI: 1.01 to 1.32) one month after the introduction of the regulation compared to the reference group (before its introduction). They were on average 2.79 times as likely to meet the regulatory requirement on homework time (95% CI: 2.47 to 3.14) than the reference group and reduced their daily total screen-viewing time by 6.4% (95% CI: -9.6 to -3.3%, approximately 10 min). The positive effects were more pronounced among high-risk groups (secondary school and urban pupils who generally spend more time in sedentary behaviour) than in low-risk groups (primary school and rural pupils who generally spend less time in sedentary behaviour). The exploratory analyses showed comparable findings.ConclusionsThis regulatory intervention has been effective in reducing total and specific types of sedentary behaviour among Chinese children and adolescents, with the potential to reduce health inequalities. International researchers and policy makers may explore the feasibility and acceptability of implementing regulatory interventions on sedentary behaviour elsewhere.

Neonatal outcomes of preterm infants with pulmonary hypertension: clustering based on prenatal risk factors.

To investigate association of prenatal risk factors and neonatal outcomes of preterm infants with pulmonary hypertension (PH). A prospective cohort study of very-low-birth-weight infants born at 22-29 weeks' gestation who received PH-specific treatment during hospitalization. Infants were classified using a two-step cluster analysis based on gestational age (GA), small-for-gestational-age (SGA), exposure to antenatal corticosteroids (ACS), histologic chorioamnionitis (HCA), and oligohydramnios. Among 910 infants, six clusters were identified: cluster A (HCA, n = 240), cluster B (oligohydramnios, n = 79), cluster C (SGA, n = 74), cluster D (no-ACS, n = 109), cluster E (no dominant parameter, n = 287), and cluster F (HCA and oligohydroamnios, n = 121). Cluster A was used as a reference group for comparisons among clusters. Compared to cluster A, cluster C (aHR: 1.63 [95% CI: 1.17-2.26]) had higher risk of overall in-hospital mortality. Clusters B (aHR: 1.52 [95% CI: 1.09-2.11]), D (aHR: 1.71 [95% CI: 1.28-2.30]), and F (aHR: 1.51 [95% CI: 1.12-2.03]) had higher risks of receiving PH-specific treatment within the first week of birth compared to cluster A. These findings may provide a better understanding of prenatal risk factors contributing to the development of PH. Pulmonary hypertension (PH), presenting as hypoxic respiratory failure, has complex etiologies in preterm infants. Although multifactorial risks for the development of PH in preterm infants are known, few studies have classified infants with similar etiologies for PH. Each cluster has distinct patterns of prenatal condition and neonatal outcome.

Rodent and broiler feeding studies with maize containing genetically modified event DP-915635-4 show no adverse effects on health or performance

Several regulatory agencies continue to require animal feeding studies to approve new genetically modified crops despite such studies providing little value in the safety assessment. Feeding studies with maize grain containing event DP-915635-4 (DP915635), a new corn rootworm management trait, were conducted to fulfill that requirement. Diets fed to Crl:CD®(SD) rats for 90 days contained up to 50% ground maize grain from DP915635, non-transgenic control, or non-transgenic reference hybrids (P1197, 6158, and 6365). Ross 708 broilers received phase diets containing up to 67% maize grain from each source for 42 days. Growth performance was compared between animals fed DP915635 and control diets; rats were further evaluated for clinical and neurobehavioral measures, ophthalmology, clinical pathology, organ weights, and gross and microscopic pathology, whereas carcass parts and select organ yields were determined for broilers. Reference group inclusion assisted in determining natural variation influence on observed significant differences between DP915635 and control groups. DP915635 maize grain diet consumption did not affect any measure evaluated in either feeding study. Results demonstrated DP-915635-4 maize grain safety and nutritional equivalency when fed in nutritionally adequate diets, adding to the existing literature confirming the lack of significant effects of feeding grain from genetically modified plants.
