Accuracy study of Angiotensin 1-7 composite index test to predict pulmonary fibrosis and guide treatment.

BACKGROUND: Pulmonary fibrosis can develop after acute respiratory distress syndrome (ARDS). The hypothesis is we are able to measure phenotypes that lie at the origin of ARDS severity and fibrosis development. The aim is an accuracy study of prognostic circulating biomarkers. METHODS: A longitudinal study followed COVID-related ARDS patients with medical imaging, pulmonary function tests and biomarker analysis, generating 444 laboratory data. Comparison to controls used non-parametrical statistics; p < 0·05 was considered significant. Cut-offs were obtained through receiver operating curve. Contingency tables revealed predictive values. Odds ratio was calculated through logistic regression. RESULTS: Angiotensin 1-7 beneath 138 pg/mL defined Angiotensin imbalance phenotype. Hyper-inflammatory phenotype showed a composite index test above 34, based on high Angiotensin 1-7, C-Reactive Protein, Ferritin and Transforming Growth Factor-ß. Analytical study showed conformity to predefined goals. Clinical performance gave a positive predictive value of 95 % (95 % confidence interval, 82 %-99 %), and a negative predictive value of 100 % (95 % confidence interval, 65 %-100 %). Those severe ARDS phenotypes represented 34 (Odds 95 % confidence interval, 3-355) times higher risk for pulmonary fibrosis development (p < 0·001). CONCLUSIONS: Angiotensin 1-7 composite index is an early and objective predictor of ARDS evolving to pulmonary fibrosis. It may guide therapeutic decisions in targeted phenotypes.

Arsenic exposure and oxidative damage to lipid, DNA, and protein among general Chinese adults: A repeated-measures cross-sectional and longitudinal study.

Arsenic-related oxidative stress and resultant diseases have attracted global concern, while longitudinal studies are scarce. To assess the relationship between arsenic exposure and systemic oxidative damage, we performed two repeated measures among 5236 observations (4067 participants) in the Wuhan-Zhuhai cohort at the baseline and follow-up after 3 years. Urinary total arsenic, biomarkers of DNA oxidative damage (8-hydroxy-2'-deoxyguanosine (8-OHdG)), lipid peroxidation (8-isoprostaglandin F2alpha (8-isoPGF2α)), and protein oxidative damage (protein carbonyls (PCO)) were detected for all observations. Here we used linear mixed models to estimate the cross-sectional and longitudinal associations between arsenic exposure and oxidative damage. Exposure-response curves were constructed by utilizing the generalized additive mixed models with thin plate regressions. After adjusting for potential confounders, arsenic level was significantly and positively related to the levels of global oxidative damage and their annual increased rates in dose-response manners. In cross-sectional analyses, each 1% increase in arsenic level was associated with a 0.406% (95% confidence interval (CI): 0.379% to 0.433%), 0.360% (0.301% to 0.420%), and 0.079% (0.055% to 0.103%) increase in 8-isoPGF2α, 8-OHdG, and PCO, respectively. More importantly, arsenic was further found to be associated with increased annual change rates of 8-isoPGF2α (ß: 0.147; 95% CI: 0.130 to 0.164), 8-OHdG (0.155; 0.118 to 0.192), and PCO (0.050; 0.035 to 0.064) in the longitudinal analyses. Our study suggested that arsenic exposure was not only positively related with global oxidative damage to lipid, DNA, and protein in cross-sectional analyses, but also associated with annual increased rates of these biomarkers in dose-dependent manners.

The National Cancer Aid monitoring (NCAM-online) of ultraviolet radiation risk and protection behavior: a population-based observational trend study with four annual online survey waves.

BACKGROUND: Ultraviolet (UV) radiation is the most important risk factor for skin cancer development. Sunlight is the main source of UV radiation in the general population. In addition, tanning beds are a source of artificial UV radiation. Since the incidence of skin cancer is increasing worldwide, it is necessary to monitor UV-related risk behaviors such as intentional indoor and outdoor tanning, as well as sun protection behavior in the general population and specific subgroups and settings. This is the aim of the National Cancer Aid Monitoring online (NCAM-online), a continuation and further development of the NCAM. METHODS: The NCAM-online is a longitudinal trend study consisting of four annual survey waves. Each year, 4,000 individuals aged 16-65 years living in Germany will be surveyed using online questionnaires. Each year, intentional indoor and outdoor tanning will be assessed. In addition, varying specific topics regarding skin cancer prevention, such as the utilization of skin cancer screening, will be addressed in the questionnaires. DISCUSSION: The findings of the NCAM-online will provide an important basis for the German Cancer Aid and Working Group on Dermatologic Prevention (Arbeitsgemeinschaft Dermatologische Prävention, ADP) to develop targeted prevention campaigns and projects aimed at preventing skin cancer. The explorative nature of the NCAM-online allows for the identification of new potential starting points for prevention and education. In addition, the longitudinal design allows for a description of the trend in the prevalence of intentional tanning. For tanning bed use, representative trend data from 2012 are available for Germany, to which NCAM-online will add annual data until 2027.

Long-term longitudinal analysis of 4,187 participants reveals insights into determinants of clonal hematopoiesis.

Clonal hematopoiesis of indeterminate potential (CHIP) is linked to diverse aging-related diseases, including hematologic malignancy and atherosclerotic cardiovascular disease (ASCVD). While CHIP is common among older adults, the underlying factors driving its development are largely unknown. To address this, we performed whole-exome sequencing on 8,374 blood DNA samples collected from 4,187 Atherosclerosis Risk in Communities Study (ARIC) participants over a median follow-up of 21 years. During this period, 735 participants developed incident CHIP. Splicing factor genes (SF3B1, SRSF2, U2AF1, and ZRSR2) and TET2 CHIP grow significantly faster than DNMT3A non-R882 clones. We find that age at baseline and sex significantly influence the incidence of CHIP, while ASCVD and other traditional ASCVD risk factors do not exhibit such associations. Additionally, baseline synonymous passenger mutations are strongly associated with CHIP status and are predictive of new CHIP clone acquisition and clonal growth over extended follow-up, providing valuable insights into clonal dynamics of aging hematopoietic stem and progenitor cells. This study also reveals associations between germline genetic variants and incident CHIP. Our comprehensive longitudinal assessment yields insights into cell-intrinsic and -extrinsic factors contributing to the development and progression of CHIP clones in older adults.

Barriers and Facilitators to Sustainable Technology Implementation in Care for People With Disabilities-Real World Data From a Three-Year Implementation Programme.

BACKGROUND: Implementation issues often impede the realisation of the potential benefits of technology in disability care organisations for people with disabilities. Therefore, we conducted a longitudinal study to gain insights into the barriers and facilitators to implementation. METHODS: From 2019 to 2022, data were collected using questionnaires and interviews during 28 implementation projects in 26 disability care organisations. RESULTS: Barriers and facilitators were identified using 9 themes and 26 subthemes. The main themes identified were finances, disability care organisations, internal collaborations, external collaborations, technology, care staff, project teams, people with disabilities, and context. Most factors mentioned as barriers in one organisation were mentioned as facilitators in others. This suggests that barriers can be resolved to improve implementation. CONCLUSION: A large number of barriers and facilitators spanning the organisation suggests that the implementation of technology should be considered an organisational reform. Acting upon them is crucial for the successful implementation of technology.

Longitudinal association between dentition status and gait speed among older Brazilian adults: SABE cohort study.

BACKGROUND: Oral health has been associated with general health conditions, but few longitudinal studies evaluated the effect of dentition status on gait speed. OBJECTIVE: This study aimed to investigate the longitudinal association between different time-varying measures of dentition status (i.e., number of teeth, the presence of periodontal pockets and the functional impact of oral health) and gait speed (outcome) in older Brazilian adults. MATERIALS AND METHODS: This was a prospective study using data from the Health, Well-being and Aging cohort study (SABE) from 2006, 2010 and 2015. The gait speed was the dependent variable and the independent variables of interest were dentition status evaluated using the number of teeth, use of dental prostheses, presence of periodontal pocket, clinical attachment loss and self-perceived poor functional oral health. Dentition status measures were obtained through clinical oral examinations, performed by trained dentists using standardized criteria proposed by the World Health Organization. Self-perceived poor functional oral health was evaluated using the functional domain of the Geriatric Oral Health Assessment Index. The longitudinal effect of dentition status on gait speed was evaluated using mixed-effects linear models. The effect of the number of teeth/periodontal pocket/attachment loss on gait speed change over time was evaluated by including an interaction term between these variables. The effect of periodontal pocket was tested only among dentate individuals. RESULTS: Data for the complete sample included 3,306 observations from 1,964 individuals. The analyses for dentate individuals included 1,883 observations from 1,149 individuals. There was a positive association between the number of teeth and mean gait speed. Individuals using dental prostheses also had higher means of gait speed than those without dental prostheses. Gait speed was lower among individuals with periodontal pockets and with attachment loss. No interaction was found between any of the indicators of dentition status and time. CONCLUSION: Gait speed was associated with dentition status and this association was constant over time.

Sickness absence after work accidents and post-traumatic stress among white-collar workers in the retail and wholesale industry; a longitudinal Swedish cohort study.

BACKGROUND: Most studies about accidents and about PTSD, respectively, have been conducted either on blue-collar workers, or on the entire working population. There are very few such studies on white-collar workers. AIM: To examine diagnosis-specific sickness absence (SA) and disability pension (DP) after a work accident or PTSD, respectively, among white-collar workers in the private retail and wholesale industry. METHODS: A prospective population-based cohort study of all 192,077 such workers aged 18-67 (44% women) in Sweden in 2012, using linked microdata from nationwide registers. We identified individuals who had secondary healthcare due to work-related accidents (n = 1114; 31% women) or to PTSD (n = 216; 79% women) in 2012-2016. Their average number of net days of diagnosis-specific SA (in SA spells > 14 days) and DP were calculated for 365 days before and 365 days after the healthcare visit. RESULTS: 35% of the women and 24% of the men had at least one new SA spell during the 365 days after healthcare due to work accidents. Among women, the average number of SA/DP days increased from 14 in the year before the visit to 31 days the year after; among men from 9 to 21 days. SA days due to fractures and other injuries increased most, while SA days due to mental diagnoses increased somewhat. 73% of women and 64% of men who had healthcare due to PTSD had at least one new SA spell in the next year. Women increased from 121 to 157 SA/DP days and men from 112 to 174. SA due to stress-related disorders and other mental diagnoses increased the most, while DP due to stress-related diagnoses and SA due to musculoskeletal diagnoses increased slightly. CONCLUSIONS: About a quarter of those who had secondary healthcare due to work accidents, and the majority of those with such healthcare due PTSD, had new SA in the following year. SA due to injury and mental diagnoses, respectively, increased most, however, SA/DP due to other diagnoses also increased slightly. More knowledge is needed on factors associated with having or not having SA/DP in different diagnoses after work accidents and among people with PTSD.

Implementation of a rural emergency department-initiated buprenorphine program in the mountain west: a study protocol.

BACKGROUND: Opioid related overdose morbidity and mortality continue to significantly impact rural communities. Nationwide, emergency departments (EDs) have seen an increase in opioid use disorder (OUD)-related visits compared to other substance use disorders (SUD). ED-initiated buprenorphine is associated with increased treatment engagement at 30 days. However, few studies assess rural ED-initiated buprenorphine implementation, which has unique implementation barriers. This protocol outlines the rationale and methods of a rural ED-initiated buprenorphine program implementation study. METHODS: This is a two-year longitudinal implementation design with repeated qualitative and quantitative measures of an ED-initiated buprenorphine program in the rural Mountain West. The Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework outlines intervention assessments. The primary outcome is implementation measured by ED-initiated buprenorphine protocol core components. Reach, adoption, and maintenance are secondary outcomes. External facilitators from an academic institution with addiction medicine and prior program implementation expertise partnered with community hospital internal facilitators to form an implementation team. External facilitators provide ongoing support, recommendations, education, and academic detailing. The implementation team designed and implemented the rural ED-initiated buprenorphine program. The program includes OUD screening, low-threshold buprenorphine initiation, naloxone distribution and administration training, and patient navigator incorporation to provide warm hand off referrals for outpatient OUD management. To address rural based implementation barriers, we organized implementation strategies based on Expert Recommendations for Implementing Change (ERIC). Implementation strategies include ED workflow redesign, local needs assessments, ED staff education, hospital leadership and clinical champion involvement, as well as patient and community resources engagement. DISCUSSION: Most ED-initiated buprenorphine implementation studies have been conducted in urban settings, with few involving rural areas and none have been done in the rural Mountain West. Rural EDs face unique barriers, but tailored implementation strategies with external facilitation support may help address these. This protocol could help identify effective rural ED-initiated buprenorphine implementation strategies to integrate more accessible OUD treatment within rural communities to prevent further morbidity and mortality.

Lack of Parental Control Is Longitudinally Associated With Higher Smartphone Addiction Tendency in Young Children: A Population-Based Cohort Study.

The purpose of the current study was to examine the risk factors of young children's smartphone addiction in a longitudinal study design. Data collected from 313 participants (mean age, 4.5 ± 0.82 years; male, 49.8%) over 4 years for Kids Cohort for Understanding of Internet Addiction Risk Factors in Early Childhood were analyzed in this study. Mixed effect models were used to evaluate the influence of various variables on the repeated measures of smartphone addiction tendency in young children over time. The multi-level analysis showed that parents' lack of control over children's smartphone use (t = -4.523; 95% confidence interval [CI], -7.32, -1.72), and parents' higher smartphone addiction proneness (t = 6.340; 95% CI, 0.23, 0.440) predicted higher smartphone addiction tendency in young children. The responsibility of the parents to prevent their children from becoming addicted to smartphones should start in a very early age when they start using the smartphones.

Food expenditure, income, and mental health: Outcomes from the UK Household Longitudinal Survey.

The incidence of mental health problems is increasing in the United Kingdom and may be associated with lower dietary quality. Food expenditure is a marker of food insecurity with potential implications for mental health. This analysis considers data collected as part of the United Kingdom Household Longitudinal Survey (UKHLS), also known as 'Understanding Society' (2009-2021) (N = 388,944) to determine the extent to which food expenditure within and outside the household, is associated with mental health, whilst controlling for demographic factors. Mental health was measured using the General Health Questionnaire (GHQ-12) for which responses were on a 4-point scale and reverse-scored so that a higher score represented more favourable mental health. Household food expenditure and food expenditure outside the home were the outcomes. Controlling for socioeconomic and demographic factors, fixed-effects models indicated that better mental health was associated with greater household food expenditure and with greater food expenditure outside the home and that this association persisted post-lockdown. Among those on lower incomes better mental health was associated with lower food expenditure. When people who identified as white and non-white were modelled separately, better mental health was associated with lower food expenditure within and beyond the household only in those who identified as white. These findings imply that the mental health of people residing in the UK, particularly those on lower incomes and those who identify as white, may benefit from spending less of the household budget on food. In achieving United Nations General Assembly (2012) Sustainable Development Goals related to poverty, hunger and in promoting mental health, policies are needed to render food more affordable and to reduce other aspects of expenditure that impact upon food budgeting.

Cross-sectional and longitudinal analysis of health-related quality of life (HRQoL) in senior and geriatric dogs.

Advancements in veterinary medicine have resulted in increased life spans for dogs, necessitating a better understanding of quality of life for older dogs. This study aimed to evaluate quality of life (QoL) progression and its potential association with mortality in senior and geriatric dogs. The Canine Owner-Reported Quality of Life Questionnaire (CORQ), consisting of 17 questions across four domains (vitality, companionship, pain, and mobility) was employed. Higher scores indicated better quality of life, with 7 as the highest potential score for each question. In a cross-sectional analysis including 92 dogs, we found an inverse correlation between overall CORQ (and all domain scores) and fractional lifespan. The domain of vitality demonstrated the lowest scores, while companionship exhibited the highest. A longitudinal analysis, including 34 dogs, revealed that when dogs reach the geriatric stage (100% of their calculated lifespan), their expected overall CORQ is 5.95 out of 7, and dogs are expected to have a monthly decline of 0.05 units in the score. Cox proportional hazard analysis demonstrated a significant association between overall CORQ scores and mortality, with dogs scoring below 5.35 being at a higher risk of mortality. This study underscores the association between aging, declining quality of life, and increased mortality risk in aging dogs.

Association of Urinary Cadmium Concentration With Cognitive Impairment in US Adults: A Longitudinal Cohort Study.

BACKGROUND AND OBJECTIVES: Studies have indicated that cadmium (Cd) exposure is associated with neurotoxicity. However, data linking Cd exposure to cognitive impairment are sparse. We aimed to investigate the association between urinary Cd concentration and cognitive impairment in US adults. METHODS: The REasons for Geographic and Racial Differences in Stroke (REGARDS) study is an ongoing population-based prospective cohort study that enrolled 30,239 Black and White US adults aged 45 years or older at baseline (2003-2007). In a randomly selected subcohort of REGARDS participants who were free of cognitive impairment or stroke at baseline, certain trace element concentrations, including urinary creatinine-corrected Cd, were measured using biospecimens collected and stored at baseline. During an average of 10 years of follow-up, global cognitive impairment was assessed annually using the Six-Item Screener, and domain-based cognitive impairment, including verbal learning, memory, and executive function, was evaluated every other year using the Enhanced Cognitive Battery. Multivariable-adjusted logistic regression models were used to examine the association between urinary Cd concentration and the odds of global or domain-based cognitive impairment. RESULTS: A total of 2,172 participants (mean age: 64.1 ± 9.0 years; female: 54.8%; Black participants: 38.7%) with available data on urinary Cd concentration, including 195 cases of global cognitive impairment and 53 cases of domain-based cognitive impairment, were included in the analyses. While there was no association between Cd and cognitive impairment in the full sample, there was a significant positive association of urinary Cd concentration with global cognitive impairment among White but not Black participants. The odds of cognitive impairment for White participants in the high urinary Cd concentration group (≥median) were doubled compared with those in the low urinary Cd group (odds ratio 2.07, 95% CI 1.18-3.64). Sex, age, region, smoking pack-years, alcohol consumption, and other related metals did not materially modify the associations of interest. DISCUSSION: Findings from this prospective cohort study suggest that urinary Cd concentrations are associated with global cognitive impairment among White but not Black individuals. Further studies with repeatedly measured Cd exposure, larger sample sizes, and longer duration are needed to confirm our findings and explore the potential explanations for the observed racial discrepancy, such as the impact of smoking.

Growing up to be mature and confident? The longitudinal interplay between the Big Five and self-esteem in adolescence.

Adolescence is a formative life phase for the development of personality characteristics. Although past findings suggest Big Five traits alongside self-esteem as indicators for successful development, little is known about their longitudinal interplay. We addressed this research gap by integrating data from three longitudinal studies (NT1 = 1,088; Mage = 16.02 years, 72% female). We apply continuous time modeling to investigate longitudinal associations between Big Five traits and self-esteem in a period of up to 1 year. Results illustrate four main findings: First, rank-order stabilities were overall high for all personality characteristics. Second, longitudinal associations between Big Five traits and self-esteem were reciprocal for extraversion, neuroticism, and openness but one-sided for agreeableness and conscientiousness on self-esteem. Effects peaked within the first month and mostly faded after 2 months. Third, the majority of cross-effects were similar in size; however, the effect from neuroticism on later values of self-esteem was stronger than vice versa. Fourth, most effects were robust against influences of gender, age, and study characteristics. Analyses with acquaintance-reports supported the results but suggested stronger effects that lasted longer than effects of self-reports. We conclude that the development of personality characteristics acts as possible sources of development for each other. All in all, the interplay between Big Five and self-esteem development appears reciprocal for some traits but was most often driven by Big Five traits. We integrate our findings into three contrasting theoretical perspectives and discuss the importance of time for a better understanding of personality development.

Longitudinal Trajectories of Estimated Glomerular Filtration Rate in a European Population of Living Kidney Donors.

A living donor (LD) kidney transplant is the best treatment for kidney failure, but LDs safety is paramount. We sought to evaluate our LDs cohort's longitudinal changes in estimated glomerular filtration rate (eGFR). We retrospectively studied 320 LDs submitted to nephrectomy between 1998 and 2020. The primary outcome was the eGFR change until 15 years (y) post-donation. Subgroup analysis considered distinct donor characteristics and kidney function reduction rate (%KFRR) post-donation [-(eGFR6 months(M)-eGFRpre-donation)/eGFRpre-donation*100]. Donors had a mean age of 47.3 ± 10.5 years, 71% female. Overall, LDs presented an average eGFR change 6 M onward of +0.35 mL/min/1.73 m2/year. The period with the highest increase was 6 M-2 Y, with a mean eGFR change of +0.85L/min/1.73 m2/year. Recovery plateaued at 10 years. Normal weight donors presented significantly better recovery of eGFR +0.59 mL/min/1.73 m2/year, compared to obese donors -0.18L/min/1.73 m2/year (p = 0.020). Noteworthy, these results only hold for the first 5 years. The subgroup with a lower KFRR (<26.2%) had a significantly higher decrease in eGFR overall of -0.21 mL/min/1.73 m2/year compared to the groups with higher KFRR (p < 0.001). These differences only hold for 6 M-2 Y. Moreover, an eGFR<50 mL/min/1.73 m2 was a rare event, with ≤5% prevalence in the 2-15 Y span, correlating with eGFR pre-donation. Our data show that eGFR recovery is significant and may last until 10 years post-donation. However, some subgroups presented more ominous kidney function trajectories.

Impact of motor dysfunction on neuropsychiatric symptom profile in patients with autopsy-confirmed Alzheimer's disease.

Motor dysfunction, which includes changes in gait, balance, and/or functional mobility, is a lesser-known feature of Alzheimer's Disease (AD), especially as it relates to the development of neuropsychiatric symptoms (NPS). This study (1) compared rates of NPS between autopsy-confirmed AD patients with and without early-onset motor dysfunction and (2) compared rates of non-AD dementia autopsy pathology (Lewy Body disease, Frontotemporal Lobar degeneration) between these groups. This retrospective longitudinal cohort study utilized National Alzheimer's Coordinating Center (NACC) data. Participants (N = 856) were required to have moderate-to-severe autopsy-confirmed AD, Clinical Dementia Rating-Global scores of ≤1 at their index visit, and NPS and clinician-rated motor data. Early motor dysfunction was associated with significantly higher NPI-Q total scores (T = 4.48, p < .001) and higher odds of delusions (OR [95%CI]: 1.73 [1.02-2.96]), hallucinations (2.45 [1.35-4.56]), depression (1.51 [1.11-2.06]), irritability (1.50 [1.09-2.08]), apathy (1.70 [1.24-2.36]), anxiety (1.38 [1.01-1.90]), nighttime behaviors (1.98 [1.40-2.81]), and appetite/eating problems (1.56 [1.09-2.25]). Early motor dysfunction was also associated with higher Lewy Body disease pathology (1.41 [1.03-1.93]), but not Frontotemporal Lobar degeneration (1.10 [0.71-1.69]), on autopsy. Our results suggest that motor symptoms in early AD are associated with a higher number and severity of NPS, which may be partially explained by comorbid non-AD neuropathology.

Identifying Population Segments by Differing Levels of COVID-19 Vaccine Confidence and Evaluating Subsequent Uptake of COVID-19 Prevention Behaviors: Web-Based, Longitudinal, Probability-Based Panel Survey.

BACKGROUND: The COVID-19 pandemic prompted the launch of the US Department of Health and Human Services' COVID-19 Public Education Campaign to boost vaccine confidence and uptake among adults, as vaccines are key to preventing severe illness and death. OBJECTIVE: Past segmentation research relevant to COVID-19 behavior has found important differences in attitudes, sociodemographics, and subsequent COVID-19 prevention behaviors across population segments. This study extends prior work by incorporating a more comprehensive set of attitudes, behaviors, and sociodemographic variables to identify population segments by differing levels of COVID-19 vaccine confidence and evaluate differences in their subsequent uptake of COVID-19 prevention behaviors. METHODS: Data were obtained from 5 waves (January 2021 to June 2022) of a web-based longitudinal, probability-based panel survey of US adults (N=4398) administered in English and in Spanish. Participants were recruited from NORC at the University of Chicago's national AmeriSpeak panel and were invited to participate across multiple waves. Latent class cluster analysis estimated segments of respondents based on over 40 COVID-19 attitudes, beliefs, behaviors, and sociodemographics as reported in wave 1. Survey-weighted cross-tabulations and bivariate regression analyses assessed differences in COVID-19 vaccine uptake, booster uptake, mask use, and social distancing in all segments across all 5 survey waves. RESULTS: A total of 6 segments (hardline nonintenders, prevention-compliant nonintenders, burned-out waiters, anxious waiters, skeptical confidents, and ready confidents) were identified, which differed by their COVID-19 vaccine confidence, prevention-related attitudes and behaviors, and sociodemographics. Cross-tabulations and regression results indicated significant segment membership differences in COVID-19 vaccine and booster timing, mask use, and social distancing. Results from survey-weighted cross-tabulations comparing COVID-19 vaccine and booster uptake across segments indicate statistically significant differences in these outcomes across the 6 segments (P<.001). Results were statistically significant for each segment (P<.01 for booster uptake among burned-out waiters; P<.001 for all other coefficients), indicating that, on average, respondents in segments with lower intentions to vaccinate reported later receipt of COVID-19 vaccines and boosters relative to the timing of vaccine and booster uptake among ready confidents. CONCLUSIONS: Results extend previous research by showing that initial beliefs and behaviors relevant to COVID-19 vaccination, mask use, and social distancing are important for understanding differences in subsequent compliance with recommended COVID-19 prevention measures. Specifically, we found that across respondent segments, the probability of vaccine and booster uptake corresponded with both COVID-19 vaccine confidence and mask use and social distancing compliance; more compliant segments were more likely to get vaccinated or boosted than less compliant segments given similar levels of vaccine confidence. These findings help identify appropriate audiences for campaigns. Results highlight the use of a comprehensive list of attitudes, behaviors, and other individual-level characteristics that can serve as a basis for future segmentation efforts relevant to COVID-19 and other infectious diseases.

The effects of substance use on non-communicable diseases among older adults aged 60 and above in the North-eastern States of India.

INTRODUCTION: The North-eastern region of India has a relatively higher prevalence of substance use, which together with poor dietary practices and a lack of physical activity is one of the key risk factors for NCDs among older adults in the region. Understanding the prevalence of NCDs and their relationship to substance use can help develop preventive strategies and sensitization in North-eastern India. OBJECTIVE: To assess the prevalence of NCDs and the strength of the association of substance abuse among the geriatric population of North-eastern states in India, for the development of preventive strategies. METHODS: Data from the Longitudinal Ageing Study in India (LASI Wave-I, 2017-18) were drawn to develop this paper. The bi-variate and binary logistic regression analyses were carried out to predict the association between non-communicable diseases and substance use adjusting select socio-demographic characteristics. RESULTS: The paper revealed the prevalence of NCDs among urban people (61.45%) is higher than among rural people (42.45%). Hypertension (37.29%) can be seen as the most prevalent disease among the following given NCDs followed by Diabetes (8.94%). The chances of having Cancer are nineteen times higher (OR = 19.8; C.I. = 18.82-20.83) if an individual has past smoking behaviour after controlling for socio-demographic and physical activity variables. CONCLUSION: Since, the high prevalence of hypertension correlated with the high level of substance abuse, require immediate attention to develop appropriate intervention strategies for its control (substance abuse) and prevention of hypertension. In a lower middle-income country like India, preventive measures, rather than curative measures will be cost-effective and helpful.

Parenting stress, dyadic coping and endocrine markers of stress and resilience in foster and biological mothers.

Foster parents have been shown to report higher levels of parenting stress but also more dyadic coping (DC) behaviors in their partnership than biological parents, which might be an important protective factor that helps them cope with daily stressors. Here, we examined how parenting stress and DC are related in foster and biological parents and whether these are reflected in long-term alterations of hypothalamic-pituitary-adrenocortical (HPA) axis activity. A total of 79 foster mothers and 131 biological mothers participated in a longitudinal study. At the initial assessment, children were aged 2-7 years and lived for an average of 18 months in their current foster family. Mothers' cortisol and dehydroepiandrosterone (DHEA) concentrations and their cortisol/DHEA ratios were assessed in scalp hair twice with approximately 11 months in between, while their perceived parenting stress and DC were measured by self-report questionnaires. Results showed no significant differences between foster mothers and biological mothers in cortisol, DHEA and cortisol/DHEA concentrations. While more DC was longitudinally related to lower levels of parenting stress across both study groups, no significant associations were found to endocrine markers. Thus, these findings indicate that increased parenting stress levels were not, or not strongly, reflected in HPA axis alterations as assessed in hair. Our findings thus add evidence for non-significant associations between self-reported perceived stress and chronic HPA axis markers. Future studies may explore whether early interventions, including those aimed at promoting and maintaining positive DC, are beneficial in preventing the development of stress-related illnesses in foster parents.

Professional football training and recovery: A longitudinal study on the effects of weekly conditioning session and workload variables.

The main purpose of this longitudinal study was to investigate football players' recovery status, through hormonal response, in relation to accumulated workload at two comparable time points of the first (T1) and second half (T2) of the competitive season. Moreover, this study investigated athletes' hormonal response to a typical weekly conditioning session (5 days before match: MD-5), at T1 and T2, to detect changes in players' recovery capability over time. Salivary cortisol (sC) and testosterone (sT) of 24 professional players (27.8 ± 4.1 years of age) were collected before, after, and 24 hours following MD-5 in two comparable microcycles of T1 and T2. GPS training data (total and high-intensity distance) of the 7 and 28 days before sampling were used to obtain athletes' acute and chronic workloads. Results showed a pre-training significant decrease of sT and an increase of sC (p<0.05) in T2, compared to T1. Moreover, athletes showed high sC and low sT levels before, after and 24 hours following MD-5 in T2. Workload analysis revealed significant correlations of chronic load with sC (r = 0.45, p = 0.056) and T/C ratio (r = -0.59; p = 0.007). These results suggested that, in professional football, chronic workload has a greater impact on players' recovery time than acute workload over the sport season. Moreover, athletes' hormonal response to the weekly conditioning session at T2 revealed an altered anabolic/catabolic balance, highlighting the key role of continuous internal and external workload monitoring during the season.

Salivary flow rate, subjective oral dryness and dental caries 5 years after haematopoietic cell transplantation.

BACKGROUND: The aim of this study was to describe salivary flow rate, subjective oral dryness and dental caries 5 years post haematopoietic cell transplantation (HCT). METHODS: HCT survivors of a previous longitudinal observational cohort study in the Netherlands (the H-OME study) were invited to participate in this additional follow-up after 5 years (the HOME2 study). During the additional follow-up appointment, stimulated (SWS) and unstimulated whole saliva (UWS) was collected, participants rated subjective oral dryness on a 0 - 10 scale, and caries lesions were assessed. Furthermore, dental records, including treatments and radiographs, were requested for the 5 years preceding and the 5 years following transplantation. Paired t-tests were performed to determine changes in UWS and SWS flow rates and subjective oral dryness from pre-HCT, and to compare the number of caries-related dental treatments (restorations, endodontic treatments or extractions) before and after HCT. Hyposalivation of UWS (< 0.2 mL/min) and SWS (< 0.7 mL/min) at 3 and 12 months, was used to explore the predictive potential of hyposalivation on a high dental treatment need (> 3 treatments) over the 5 years post-HCT. RESULTS: Five years post-HCT, 39 HCT survivors were included. The mean UWS flow rate was 0.36 mL/min (SD 0.26) and the mean SWS flow rate 1.02 (SD 0.57); survivors were diagnosed with a median of 0 dentine lesions (range 0 - 12) and 73% reported a subjective oral dryness score ≥ 1. Survivors underwent a median of 3 (range 0 - 20) dental treatments during the 5 years following transplantation. The mean difference in UWS 5 years post-HCT compared to pre-HCT was 0.03 (95% CI: -0.07 - 10.12), the mean difference for SWS was -0.18 (95% CI: -0.45 - 0.08) and for subjective oral dryness 1.2 (95% CI: 0.2 - 2.1). In the 5 years post-HCT, non-significantly more treatments were performed compared to the 5 years pre-HCT (mean difference: 0.5, 95%CI: -1.2 - 2.2). Seventy eight percent of patients with hyposalivation of SWS at 12 months had a high dental treatment need, compared with 38% with no hyposalivation. CONCLUSIONS: Five years post-HCT, mean UWS and SWS flow rates were not significantly different from pre-HCT levels but subjective oral dryness scores were elevated.
