RESUMEN

BACKGROUND: Bruxism is a behaviour that has several consequences in an individual's life, especially when it starts in childhood. However, bruxism can be a potential protective factor, which is an attribute that reduces the chance of a negative health outcome. OBJECTIVES: To evaluate the incidence of sleep bruxism (SB) and dental wear in children and adolescents. MATERIALS AND METHODS: This longitudinal study began in 2014 and 2016 (baseline) with initial 1816 children followed for 5 and 3 years, respectively. The follow-up data collection started in 2019. The diagnosis of SB was parents report (baseline) and self-report (follow-up) due to age groups of each phase, and questions related to symptoms of SB were collected. Five calibrated examiners (kappa >0.7) collected the clinical data. The clinical variables were dental erosion and dental wear. Contextual, individual, behaviour and clinical characteristics were collected. A multilevel logistic regression model was used to investigate the association of contextual, individual, behaviour and clinical characteristics with SB. Poisson regression for repeated measures was performed to evaluate the incidence of SB and dental wear (incidence rate ratio-IRR and confidence interval-95% CI). RESULTS: Two hundred and fifty-three children and adolescents answered questionnaires and were clinically examined. The mean age of the follow-up in 2019 was 11.25 years old (±2.19). There was no increase in the incidence of SB (95% CI: 0.74-1.35). Children/adolescents had a 2.2 higher risk to present dental wear (95% CI: 1.89-2.60). SB at the follow-up was associated with the contextual variable, earache, erosion and awake bruxism. CONCLUSIONS: In this population, children with SB remained with this behaviour and showed higher dental wear over the years.

RESUMEN

AIM: As data are sparse on the long-term association between periodontal diseases and development of metabolic syndrome (MetS), we investigated their relationship in a Thai cohort over a 10-year observational period. METHODS: Medical records and data on periodontal assessments of 2161 employees of the Electricity Generating Authority of Thailand collected at two time points, 2003 and 2013, were used. Experienced periodontists used standard national and international criteria to define periodontitis and MetS. The impact of baseline periodontitis on subsequent MetS incidence and its components was evaluated using regression analyses. RESULTS: The severity and extent of periodontitis significantly predicted MetS incidence over a decade, with a higher incidence of MetS in individuals with poorer periodontal health. A single percentage increase in the periodontitis extent raised the risk of MetS incidence by 0.4% and the risk of developing individual components of MetS by 0.2%. Independent of periodontal health, age of an individual emerged as a factor impacting MetS development. CONCLUSION: This study highlights the potential effect of the severity and extent of periodontitis on the increased incidence and progression of MetS. Hyperglycaemia and hypertension were the two MetS components most significantly affected by the existence of periodontitis.

RESUMEN

BACKGROUND: Research into the impact of social relationships on childhood and adolescent health and wellbeing has been largely limited to children's relationships with other humans, while studies into the impact of pet ownership are sparse and have generally not adjusted for potential confounders. This study aimed to investigate the association between pet ownership and a range of developmental outcomes in childhood and adolescence. METHODS: Data were self-reports and direct assessments of approx. 14,000 children from the Avon Longitudinal Study of Parents and Children (ALSPAC). Multivariable regression models adjusting for confounding factors examined associations between developmental outcome measures (emotional health, behavioural development, cognitive development, language development, educational attainment) and concurrent pet ownership, including species, and also longitudinal pet ownership history and pet-interaction where possible. Analyses model numbers using multiple imputation varied from n = 393-8963. RESULTS: In cross-sectional analyses, owning a dog (b = 0.24, [0.06-0.41], p = .004) and owning other/miscellaneous pets (b = 0.18, [0.03-0.33], p = .021) at age 3 were associated with higher prosocial behaviour score. Owning a pet was associated with a higher non-verbal communication score at age 2 (cross-sectional, b = 0.18, [0.04-0.32], p = .014), and a higher language development score at age 5 (cross-sectional, b = 1.01, [0.18-1.83], p = .017). However, pet ownership was associated with lower educational attainment across a number of academic subjects and timepoints, in both cross-sectional and longitudinal analyses. It was also cross-sectionally linked to hyperactivity at age 3 and conduct problems at age 3 and 11. Furthermore, at age 8, cross-sectional analysis showed that children who owned any pets (OR [95% CI]: 0.85 [0.73-0.98], p= ·026) or cats (0.83, [0.73-0.95], p= ·006) had lower odds of high self-esteem (scholastic competence). CONCLUSIONS: Using a large, well-designed longitudinal study and adjusting for key confounders, we found little evidence of cross-sectional or longitudinal associations between pet ownership and emotional health or cognitive outcomes in children. There may, however, be some cross-sectional and longitudinal association with poorer educational attainment and a positive impact on social interactions as seen through associations with enhanced language development and prosocial behaviour. This study demonstrates the importance of adjustment for confounding variables and suggests that, contrary to popular belief, positive impacts of pet ownership on childhood development may be mainly limited to social behaviour and language development.

RESUMEN

AIM: To compare the job crafting strategies nurse mentors use when mentoring students versus during periods of respite and to assess the effectiveness of these strategies in reducing instances of missed nursing care (MNC). BACKGROUND: Nurses who serve as mentors may have to train a group of nursing students on top of their routine nursing duties. The corresponding high workloads and limited resources may force them to decide which nursing care to delay or omit (i.e., MNC). The mentors' initiative and the actions they take to address the multiple job requirements which do not align with the organization's resources are referred to as job crafting strategies. Mentors can use these strategies to shape their role as nurses as well as their role as mentors, depending on their motives and personality. DESIGN: A longitudinal study with data collected at two time points. METHODS: One hundred nurse mentors completed validated questionnaires assessing job crafting strategies, MNC and work overload while actively mentoring students. Eighty returned for a follow-up during a non-mentoring period three months later. Data analysis included paired t-tests and hierarchical multivariable linear regressions. RESULTS: No significant differences were found in MNC between the two points (1.83 SD 0.6 vs. 1.82 SD 0.75; p=0.942). A decrease in hindering demands was noted during active mentoring compared with respite (2.6 SD 0.97 vs. 2.84 SD 0.96; p=0.038). Enhancing structural job resources was significantly negatively correlated with MNC during active mentoring, while enhancing challenging job demands was positively correlated with MNC during these periods (ß=0.48, p=0.18 and ß=-0.35, p=0.014, respectively). CONCLUSION: Nurse mentors can effectively reduce MNC by focusing on enhancing structural resources and limiting challenging demands during mentoring periods. It is essential for healthcare organizations to support nurse mentors with manageable workloads and necessary resources to maintain high-quality care.

RESUMEN

Introduction: This study aimed to identify the dual trajectories of social participation (SP) and frailty index (FI) among Chinese older adults, and investigate common influential factors of both trajectories. Methods: Utilizing data from the Chinese Longitudinal Healthy Longevity Survey (CLHLS) 2008-2018 surveys, 1,645 individuals were analyzed. A group-based dual trajectory model and logistic regression were used to examine trajectories, their interrelations and shared influencing factors. Results: This study identified three SP, two FI trajectories and six distinct sub-groups of individuals. The study confirmed a long-term, interrelated relationship between two outcomes and identified some common factors. Compared to participants in the lower SP trajectory, those who followed the middle SP trajectory and higher SP trajectory had increased probabilities of belonging to the slow-growth FI trajectory (90.28 and 99.71%, respectively). And the participants in the slow-growth FI exhibited higher probabilities of belonging to the middle SP and the higher SP trajectory (37.64 and 25.34% higher, respectively) compared with those in the rapid-growth FI trajectory. Age, marital status, and drinking status were mutual factors associated with the dual trajectories. Discussion: The results showed significant associations between higher levels of frailty and lower levels of social participation. Related intervention policies should consider the dual trajectories and the common factors that underlie these trajectories of SP and FI.

RESUMEN

BACKGROUND: Prior research has shown that using lifetime abstainers as the reference group to examine the association between alcohol use and health-related consequences has several disadvantages. The aim of the present study was to examine the consistency of self-reported lifetime abstention and never-binge drinking, respectively, using national, longitudinal data collected in 2019 and 2020. Additionally, the prevalence of alcohol-related morbidity among lifetime abstainers was examined by linking survey data to alcohol-related morbidity data in a national patient register. METHODS: Data come from the Danish Health and Wellbeing Survey in 2019 and from a follow-up survey of the same individuals in 2020. A random sample of 14,000 individuals aged 15 years or older was drawn in mid-August 2019. Data were collected between September and December 2019. All those who were invited to the survey in 2019 and who were still alive and living in Denmark were invited to participate in a follow-up survey in 2020. Data in both waves were collected by self-administered questionnaires. Both questionnaires included the standard questions on alcohol consumption from the European Health Interview Survey model questionnaire. Information on alcohol-related morbidity was obtained from the Danish National Patient Register. RESULTS: In all, 5000 individuals completed the questionnaire in both waves. Approximately half (44.4%) of the individuals who declared that they were lifetime abstainers in 2020 (n = 252) had reported in 2019 to have drunk at some point in their life. Moreover, 39.7% contradicted earlier reported binge drinking. Furthermore, 2.4% of the respondents who defined themselves as lifetime abstainers in 2020 had earlier been diagnosed with an alcohol-related health condition. CONCLUSION: The present research reaffirms previous studies which have found self-reported lifetime abstainers to be unreliable as a consistent reference group. Additionally, the results indicated that a non-negligible proportion of lifetime abstainers had been diagnosed with an alcohol-related health condition.

RESUMEN

OBJECTIVE: The aim of this study was compare all cause mortality across three time periods with a focus on sex differences after revascularisation for chronic limb threatening ischaemia between 1994 and 2013 in Sweden. METHODS: In this observational registry study, patients registered in the Swedish vascular registry (Swedvasc), revascularised between 1994 and 2013 with open or endovascular infra-inguinal procedures, were divided into three time periods: 1994 - 1999, 2000 - 2006, and 2007 - 2013. Patients were followed for five years. Poisson regression was used to compare 30 day mortality, presented as adjusted relative risk ratio (aRR). Adjusted restricted mean survival time (aRMST) differences at five years were compared with a generalised linear model. The analyses were adjusted for age, comorbidities, and endovascular or open surgery. Comparison with the general Swedish population was also conducted with age adjusted standardised mortality ratios. Results are presented with the 95% confidence intervals (CI). RESULTS: The study showed increasing 30 day mortality, with an aRR of 1.47 (95% CI 1.31 - 1.65) for women and aRR of 1.20 (95% CI 1.06 - 1.35) for men, per time period. In women, the five year RMST decreased from the first to the third period, with an aRMST of -45 (95% CI -59 - -32) days per period. In men, the aRMST increased 32 (95% CI 18 - 47) days per period. When comparing sexes, women showed lower 30 day mortality and higher five year survival than men in the first time period, but a significantly worse development over time periods than for men. Corresponding findings were observed in comparison with the general Swedish population. CONCLUSION: This study showed an increased 30 day mortality in women and men across the periods, most evident in women. Men showed an increased five year survival across the periods, whereas opposite findings were recorded for women. The dismal trend over time for women could not be explained by increased age or a higher prevalence of comorbidities.

RESUMEN

Background: Rehabilitation is recognized as an effective means of alleviating the symptoms of Parkinson's disease (PD) and improving the physical and cognitive functions of patients with PD. However, research often focuses on short-term outcomes such as functioning and quality of life. This study investigated the association between the length of stay in rehabilitation and mortality among patients with PD. Methods: Using the Korean National Health Insurance Service database, we identified 636 participants diagnosed with PD who received rehabilitation. The main outcome was all-cause mortality. We used a Cox proportional hazards regression model to examine the relationship between length of stay in rehabilitation and mortality among patients with PD. Results: The final sample comprised 374 females (58.81%) and 262 males (41.19%). A survival analysis revealed a significant association between the length of stay in rehabilitation and mortality, with a decrease in mortality of 16.1% in patients with PD who received one year of rehabilitation (hazard ratio = 0.839, 95% confidence interval = 0.788-0.895). Conclusion: Our findings underscore the potential benefits of timely implementation of rehabilitative interventions in patients with PD and the need for comprehensive and long-term rehabilitation strategies. It also highlights the necessity of such services for patients with PD and the importance of developing patient-centered rehabilitation guidelines.

RESUMEN

More than one-in-eight young adults in the US between the ages of 16 to 24 were not in employment, education, or training (NEET) in 2020 - a level not seen since the Great Recession. This study examines the long-term association between NEET status in emerging adulthood and later depressive symptoms using the National Longitudinal Study of Adolescent to Adult Health (1995-2018). Growth curve models chart the association between NEET status and depressive symptoms over time in the US. The analytic sample includes 9,349 individuals and 28,047 person-wave observations for respondents between ages 18 to 43. In a fully specified model, respondents who reported NEET status in emerging adulthood (ages 18-26), exhibited greater depressive symptoms across emerging adulthood through early midlife (ages 33-43) (b=0.44, 95% CI 0.33, 0.54) compared to those participating in employment, education, or training. Associations persisted even after accounting for early life disadvantage and using propensity score matching to further diminish possible sources of bias. Results indicate that disconnection from school and work during emerging adulthood may constitute a risk factor for depressive symptoms through early midlife.

RESUMEN

AIM: To examine the relationship between preterm birth and hospitalisation for paediatric complex chronic conditions. METHODS: We conducted a cohort study of 1 269 745 children born between 2006 and 2022 in Quebec, Canada. We classified preterm birth as extreme (<28 weeks), very (28-31 weeks), and moderate (32-36 weeks). The outcome was hospitalisation for complex chronic conditions, including neurologic, neuromuscular, cardiovascular, respiratory, renal, gastrointestinal, haematologic, immunologic, endocrine, and neoplastic disorders up to 16 years of age. We computed adjusted hazard ratios (HR) and 95% confidence intervals (CI) for the association between preterm birth and complex chronic conditions during 9 948 734 person-years of follow-up. RESULTS: Hospitalisation rates for complex chronic conditions were higher for children born preterm than at term (6.88 vs. 2.24 per 1000 person-years). Preterm birth was associated with all complex chronic conditions, especially respiratory (HR 4.64, 95% CI 4.01-5.37), cardiovascular (HR 3.68, 95% CI 3.47-3.90), and neurologic disorders (HR 3.48, 95% CI 3.21-3.77). Associations were present at all ages and for all degrees of prematurity, but were strongest with extreme prematurity. CONCLUSION: Preterm birth increases the risk of hospitalisation for complex chronic conditions up to age 16 years. Preterm children may benefit from enhanced care throughout childhood and adolescence.

RESUMEN

BACKGROUND: Longitudinal studies can generate valuable scientific knowledge, but can be compromised by systematic attrition. Previous research shows that sociodemographic characteristics (eg, ethnicity, age, educational level, socioeconomic circumstances) are associated with attrition rates. However, little is known about whether these characteristics differ by ethnicity, and how this impacts cohort retention strategies. METHODS: Using antenatal to 12-year data from the Growing Up in New Zealand birth cohort study (N=6743), we examined transversal response rates by ethnicity (Maori, Pacific, Asian, European), used sequence analysis and cluster analysis to identify unique longitudinal response patterns, and binary logistic regression to examine ethnic-specific sociodemographic characteristics associated with these response patterns. RESULTS: The overall response rate at 12 years was 71.0%, with ethnic differences in response rates widening over the six data collection waves. Three longitudinal response patterns were identified: frequent responders (65.2%), intermittent non-responders (29.6%) and frequent non-responders (5.2%). Sociodemographic characteristics such as younger maternal age and lower maternal education were associated with a higher likelihood of membership in the non-response clusters across all ethnic groups. However, there were also important nuances by ethnicity. Individual level factors (eg, household material deprivation and maternal general health) tended to be associated with non-response for Europeans, whereas structural level factors (eg, area-level deprivation and racial discrimination) tended to be associated with non-response for Maori, Pacific and Asian peoples. CONCLUSION: Ethnic differences in longitudinal response patterns are due to multiple factors of disadvantage, and therefore require targeted retention strategies. Stratifying analyses by ethnicity is important for revealing nuanced insights.

RESUMEN

BACKGROUND: Depression is prevalent among lung cancer patients undergoing chemotherapy, and the symptom cluster of fatigue-pain-insomnia may influence their depression. Identifying characteristics of patients with different depression trajectories can aid in developing more targeted interventions. This study aimed to identify the trajectories of depression and the fatigue-pain-insomnia symptom cluster, and to explore the predictive factors associated with the categories of depression trajectories. METHODS: In this longitudinal study, 187 lung cancer patients who were undergoing chemotherapy were recruited and assessed at the first (T1), second(T2), and fourth(T3) months using the Patient Health Questionnaire-9 (PHQ-9), the Brief Pain Inventory (BPI), the Brief Fatigue Inventory (BFI), and the Athens Insomnia Scale (AIS). Growth Mixture Model (GMM) and Latent Class Analysis (LCA) were used to identify the different trajectories of the fatigue-pain-insomnia symptom cluster and depression. Binary logistic regression was utilized to analyze the predictive factors of different depressive trajectories. RESULTS: GMM identified two depressive trajectories: a high decreasing depression trajectory (40.64%) and a low increasing depression trajectory (59.36%). LCA showed that 48.66% of patients were likely members of the high symptom cluster trajectory. Binary logistic regression analysis indicated that having a history of alcohol consumption, a higher symptom cluster burden, unemployed, and a lower monthly income predicted a high decreasing depression trajectory. CONCLUSIONS: Depression and fatigue-pain-insomnia symptom cluster in lung cancer chemotherapy patients exhibited two distinct trajectories. When managing depression in these patients, it is recommended to strengthen symptom management and pay particular attention to individuals with a history of alcohol consumption, unemployed, and a lower monthly income.

RESUMEN

OBJECTIVE: Dental caries is one of the most prevalent chronic non-communicable diseases worldwide. There is a lack of evidence, especially in adult populations, documenting caries disease progression considering lesion severity, activity and tooth surface-level characteristics. The study aimed to investigate the extent to which primary active caries lesions in adults affect caries lesions progression compared with inactive caries lesions over a 2-year follow-up period, considering their severity, surface and tooth type. METHODS: A prospective study data set from a cohort of workers in a factory in Belarus were used. Participants aged 18-64 years with 20 or more natural teeth were included in the study. The participants were clinically examined twice within an interval of 2 years and completed a self-reported questionnaire. One calibrated examiner evaluated caries lesions using the International Caries Detection and Assessment System (ICDAS) and the Nyvad system. The primary outcome was caries lesions' progression. The lesion was classified as 'progressed' if it turned to a more advanced severity stage, was restored or missing/extracted due to caries. A multilevel Poisson regression was used to estimate the association between baseline caries lesions' characteristics and caries lesion progression. RESULTS: Out of 495 participants, 322 people completed clinical examinations at baseline and 2 years later, with an attrition rate of 35%. The prevalence of active DS1-6 and DS5-6 lesions at the baseline was 83.8% and 64.8%, respectively. In 2 years, 24% of active non-cavitated and 31% of active micro-cavitated/shadowed caries lesions progressed, while 15% of inactive caries lesions, non- or micro-cavitated/shadowed, progressed. The adjusted rate ratio (RR) for ICDAS3 + 4 caries lesions progression was 1.41 (CI 95% 1.16, 1.70) than ICDAS1 + 2 lesions. The RR for ICDAS1 + 2, active and ICDAS3 + 4, active lesions was 1.78 (CI 95%, 1.40, 2.27) and 1.97 (CI 95%, 1.53, 2.55), respectively than ICDAS1 + 2, inactive lesions. The RR for caries lesions progression on proximal surfaces and on pits and fissures was 1.57 (CI 95%, 1.30, 1.89) and 1.37 (CI 95%, 1.11, 1.67), respectively than smooth surface lesions. CONCLUSION: In caries active adults over 2 years, most non- and micro-cavitated/shadowed active and inactive caries lesions did not progress. Among caries lesions that showed progression, more severe lesions were more likely to progress than less severe lesions; active lesions were more likely to progress than inactive lesions. Pit and fissure caries lesions and proximal lesions were more likely to progress than smooth surface lesions.

RESUMEN

Non-alcoholic fatty liver disease (NAFLD) is a relatively common disease, and preventing its occurrence is important for both individual health and reducing social costs. Shift work is reported to have several negative effects on health. An association has been observed between NAFLD and both sleep time and quality; however, this association remains unclear in night shift workers. We aimed to evaluate the relationship between shift work and the incidence of NAFLD. Overall, 45,149 Korean workers without NAFLD were included at baseline. NAFLD was defined as the presence of a fatty liver observed on ultrasonography without excessive alcohol use. incidence rate ratios for incident NAFLD were estimated using negative binomial regression according to age groups (20s, 30s, 40s, and 50s). In the 20s age group, shift work showed a significant incidence rate ratio (IRR) for NAFLD in all models. After adjusting for all variables, the IRR (95% confidence interval) was 1.24 (1.08-1.43) in the 20s age group. In their 20s, a significant association between shift work and incident NAFLD was consistently observed among women and workers with poor sleep quality. In this large-scale cohort study, shift work was significantly associated with the development of NAFLD among young workers in their 20s.

RESUMEN

OBJECTIVES: We are yet to understand how continuous participation in organized sports, dropout from organized sports, or complete non-participation affect adolescents' trajectories of physical fitness and body mass index (BMI). Thus, the aim was to examine longitudinal changes in cardiorespiratory and muscular fitness, and BMI between adolescents 1) who continued or started organized sport participation, 2) who dropped out, and 3) who never participated in organized sport or dropped out before adolescence. DESIGN: Longitudinal observational study. METHODS: Over four years (2017-2021), sport participation, cardiorespiratory and muscular fitness, and BMI data were collected annually from 963 participants (Mage = 11.25 ±â€¯0.31). Latent growth curve models were utilized to examine levels (baseline) and slopes (rate of change) of BMI, cardiorespiratory, and muscular fitness in each sport participation group. RESULTS: Fitness levels significantly varied among groups. Continuing sport participants exhibited the highest levels, non-participants the lowest. Both groups showed significant improvements in cardiorespiratory and muscular fitness over time. Dropouts had higher baseline fitness than non-participants but demonstrated no change in cardiorespiratory fitness over time and a significantly smaller increase in muscular fitness than the two other groups. BMI increased similarly in all groups, with non-participants starting at higher baseline levels. CONCLUSIONS: Individuals who continually participated in sports maintained higher levels of fitness than individuals who did not participate in organized sports across adolescence. However, individuals who dropped out of organized sports, showed plateau in their fitness improvements, suggesting that the physical activity previously obtained through organized sports may not be replaced elsewhere.

RESUMEN

Introduction: Medications are a fundamental part of the treatment of multiple pathologies. However, despite their benefits, some are considered potentially inappropriate medications for older people given their safety profile. Epidemiological data differences related to potentially inappropriate medications make it difficult to determine their effects on elderly people. Objective: To estimate the prevalence and types of potentially inappropriate medications using the 2019 Beers Criteria® in a cohort of adults older than 65 years. Materials and methods: We performed an observational, multicenter, retrospective, longitudinal study of a four-year follow-up of potentially inappropriate medications in community-dwelling older adults. Results: We followed 820 participants from five cities for four years (2012-2016) and evaluated them in three different moments (m1 = 2012, m2 = 2014, and m3 = 2016). The average age was 69.07 years, and 50.9% were women. The potentially inappropriate medication prevalence in the participants was 40.24%. The potentially inappropriate medications' mean among the studied subjects in the first moment was 1.65 (SD = 0.963), in the second was 1.73 (SD = 1.032), and in the third was 1.62 (SD = 0.915). There were no statistical differences between measurements (Friedman test, value = 0.204). The most frequent potentially inappropriate medications categories were gastrointestinal (39.4%), analgesics (18.8%), delirium-related drugs (15.4%), benzodiazepines (15.2%), and cardiovascular (14.2%). Conclusions: About half of the population of the community-dwelling older adults had prescriptions of potentially inappropriate medications in a sustained manner and without significant variability over time. Mainly potentially inappropriate medications were gastrointestinal and cardiovascular drugs, analgesics, delirium-related drugs, and benzodiazepines.

Introducción. Los fármacos son parte fundamental del tratamiento de múltiples enfermedades.

La edad promedio fue de 69,07 años y el 50,9 % eran mujeres. La prevalencia de medicamentos potencialmente inapropiados en los participantes fue del 40,24 %. El promedio de estos medicamentos entre los sujetos estudiados en el primer momento fue de 1,65 (DE = 0,963), en el segundo fue de 1,73 (DE = 1,032) y en el tercero fue de 1,62 (DE = 0,915). No hubo diferencias estadísticas entre las mediciones (prueba de Friedman, p = 0,204). Las categorías de los medicamentos potencialmente inapropiados más frecuentes fueron: gastrointestinales (39,4 %), analgésicos (18,8 %), relacionados con delirium (15,4 %), benzodiacepinas (15,2 %) y cardiovasculares (14,2 %). Conclusiones. En cerca de la mitad de la población de adultos mayores de la comunidad, se prescribieron medicamentos potencialmente inapropiados de manera sostenida y sin variabilidad importante en el tiempo. Los más recetados fueron aquellos para tratar malestares gastrointestinales y cardiovasculares, analgésicos, para el delirium y benzodiacepinas.

RESUMEN

BACKGROUND: Non-suicidal self-injury (NSSI) is common among adolescents receiving inpatient psychiatric treatment and the months post-discharge is a high-risk period for self-injurious behavior. Thus, identifying predictors that shape the course of post-discharge NSSI may provide insights into ways to improve clinical outcomes. Accordingly, we used machine learning to identify the strongest predictors of NSSI trajectories drawn from a comprehensive clinical assessment. METHODS: The study included adolescents (N = 612; females n = 435; 71.1%) aged 13-19-years-old (M = 15.6, SD = 1.4) undergoing inpatient treatment. Youth were administered clinical interviews and symptom questionnaires at intake (baseline) and before termination. NSSI frequency was assessed at 1-, 3-, and 6-month follow-ups. Latent class growth analyses were used to group adolescents based on their pattern of NSSI across follow-ups. RESULTS: Three classes were identified: Low Stable (n = 83), Moderate Fluctuating (n = 260), and High Persistent (n = 269). Important predictors of the High Persistent class in our regularized regression models (LASSO) included baseline psychiatric symptoms and comorbidity, past-week suicidal ideation (SI) severity, lifetime average and worst-point SI intensity, and NSSI in the past 30 days (bs = 0.75-2.33). Only worst-point lifetime suicide ideation intensity was identified as a predictor of the Low Stable class (b = -8.82); no predictors of the Moderate Fluctuating class emerged. CONCLUSIONS: This study found a set of intake clinical variables that indicate which adolescents may experience persistent NSSI post-discharge. Accordingly, this may help identify youth that may benefit from additional monitoring and support post-hospitalization.

RESUMEN

Background: Systemic lupus erythematosus (SLE) is a multi-system autoimmune disease that significantly affects both the physical and mental health of patients. Psychosocial support systems play a crucial role in managing chronic diseases, yet their specific impact on the disease activity of SLE patients remains unclear. This study aims to explore the dynamic relationship between disease activity in SLE patients and various types of psychosocial support systems. Methods: We conducted a retrospective longitudinal observational study, including 150 SLE patients who received treatment at our hospital from January 2022 to January 2023. Emotional support, tangible support, social interaction support, and informational support were assessed using the revised Social Support Rating Scale. Disease activity was quantified using the European Consensus Lupus Activity Measurement. The relationship between psychosocial support and disease activity was analyzed using Spearman's rank correlation coefficient and multiple linear regression models, with Bootstrap resampling employed to test the robustness of the results. Results: We found a significant negative correlation between psychosocial support and SLE disease activity, with emotional support, social interaction support, and informational support showing stronger negative correlations. Multiple regression analysis revealed that the inhibitory effects of emotional support, social interaction support, and informational support on disease activity increased over time. Although the impact of tangible support was not statistically significant, it gradually became more apparent over time. Conclusion: Our findings indicate a significant negative correlation between psychosocial support and SLE disease activity, particularly with emotional support, social interaction support, and informational support. Over time, the impact of tangible support also becomes evident. These findings provide important references for the comprehensive treatment and management of SLE patients. However, due to the observational nature of the study, the causality of this relationship requires further exploration.

RESUMEN

The use of flow cytometry in mice is constrained by several factors, including the limited availability of mouse-specific antibodies and the need to work with small volumes of peripheral blood. This is particularly challenging for longitudinal studies, as serial blood samples should not exceed 10% of the total blood volume in mice. To address this, we have developed two novel flow cytometry panels designed to extensively analyze immune cell populations in mice during longitudinal studies, using only 50 µL of peripheral blood per panel. Additionally, a third panel has been designed to conduct a more detailed analysis of cytotoxic and inhibitory markers at the end point. These panels have been validated on a lipopolysaccharide (LPS)-induced lung inflammation model. Two experiments were conducted to 1) validate the panels' sensitivity to immune challenges (n=12) and 2) to assess intrinsic variability of measurements (n=5). In both experiments, we collected 50 µL of peripheral blood for each cytometry panel from the maxillary venous sinus. All antibodies were titrated to identify the optimal concentration that maximized the signal from the positive population while minimizing the signal from the negative population. Samples were processed within 1 hour of collection using a MACSQuant Analyzer 16 cytometer. Our results demonstrate that these immunological panels are sensitive enough to detect changes in peripheral blood after LPS induction. Moreover, our findings help determine the sample size needed based on the immune population variability. In conclusion, the panels we have designed enable a comprehensive analysis of the murine immune system with a low blood volume requirement, enabling the measure of both absolute values and relative percentages effectively. This approach provides a robust platform for longitudinal studies in mice and can be used to uncover significant insights into immune responses.

RESUMEN

OBJECTIVES: To verify the association between the consumption of red and processed meats and the incidence of hypertension in participants of the Longitudinal Study of Adult Health. METHODS: This was a cohort with data from the baseline (2008-2010) and second wave (2012-2014) with 8,089 public workers of both sexes and different racial groups, with mean age of 49 ± 8 years (35-74 years old). Meat consumption (g/d) was estimated using a food frequency questionnaire and was divided into consumption tertiles. Hypertension was defined as systolic blood pressure ≥140 mm Hg and/or diastolic ≥90 mm Hg and/or antihypertensive medication. Cox proportional hazards models were used to estimate adjusted Hazard Ration (HRs) and 95% confidence interval (CI) for incident hypertension. RESULTS: A total of 1186 incident cases of hypertension were identified. Even adjusting for confounders, such as urinary Na/K (sodium/potassium) ratio and BMI (body mass index), participants in the second (HR:1.19; 95% CI 1.03-1.30) and third (HR:1.30; 95% CI:1.11-1.53) tertile of processed meat consumption had a higher risk of developing hypertension than those in the first tertile. We did not find a significant association between red meat consumption and hypertension. CONCLUSIONS: The increased risk of developing hypertension is associated with moderate and high consumption of processed meats but not with consumption of red meat.
