Intermittent Fasting Improves Social Interaction and Decreases Inflammatory Markers in Cortex and Hippocampus.

Autism spectrum disorder (ASD) is a psychiatric condition characterized by reduced social interaction, anxiety, and stereotypic behaviors related to neuroinflammation and microglia activation. We demonstrated that maternal exposure to Western diet (cafeteria diet or CAF) induced microglia activation, systemic proinflammatory profile, and ASD-like behavior in the offspring. Here, we aimed to identify the effect of alternate day fasting (ADF) as a non-pharmacologic strategy to modulate neuroinflammation and ASD-like behavior in the offspring prenatally exposed to CAF diet. We found that ADF increased plasma beta-hydroxybutyrate (BHB) levels in the offspring exposed to control and CAF diets but not in the cortex (Cx) and hippocampus (Hpp). We observed that ADF increased the CD45 + cells in Cx of both groups; In control individuals, ADF promoted accumulation of CD206 + microglia cells in choroid plexus (CP) and increased in CD45 + macrophages cells and lymphocytes in the Cx. Gestational exposure to CAF diet promoted defective sociability in the offspring; ADF improved social interaction and increased microglia CD206 + in the Hpp and microglia complexity in the dentate gyrus. Additionally, ADF led to attenuation of the ER stress markers (Bip/ATF6/p-JNK) in the Cx and Hpp. Finally, biological modeling showed that fasting promotes higher microglia complexity in Cx, which is related to improvement in social interaction, whereas in dentate gyrus sociability is correlated with less microglia complexity. These data suggest a contribution of intermittent fasting as a physiological stimulus capable of modulating microglia phenotype and complexity in the brain, and social interaction in male mice.

Light-Induced Transformation of Virus-Like Particles on TiO2.

Titanium dioxide (TiO2) shows significant potential as a self-cleaning material to inactivate severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and prevent virus transmission. This study provides insights into the impact of UV-A light on the photocatalytic inactivation of adsorbed SARS-CoV-2 virus-like particles (VLPs) on a TiO2 surface at the molecular and atomic levels. X-ray photoelectron spectroscopy, combined with density functional theory calculations, reveals that spike proteins can adsorb on TiO2 predominantly via their amine and amide functional groups in their amino acids blocks. We employ atomic force microscopy and grazing-incidence small-angle X-ray scattering (GISAXS) to investigate the molecular-scale morphological changes during the inactivation of VLPs on TiO2 under light irradiation. Notably, in situ measurements reveal photoinduced morphological changes of VLPs, resulting in increased particle diameters. These results suggest that the denaturation of structural proteins induced by UV irradiation and oxidation of the virus structure through photocatalytic reactions can take place on the TiO2 surface. The in situ GISAXS measurements under an N2 atmosphere reveal that the virus morphology remains intact under UV light. This provides evidence that the presence of both oxygen and UV light is necessary to initiate photocatalytic reactions on the surface and subsequently inactivate the adsorbed viruses. The chemical insights into the virus inactivation process obtained in this study contribute significantly to the development of solid materials for the inactivation of enveloped viruses.

Discovering dynamic laws from observations: The case of self-propelled, interacting colloids.

Active matter spans a wide range of time and length scales, from groups of cells and synthetic self-propelled colloids to schools of fish and flocks of birds. The theoretical framework describing these systems has shown tremendous success in finding universal phenomenology. However, further progress is often burdened by the difficulty of determining forces controlling the dynamics of individual elements within each system. Accessing this local information is pivotal for the understanding of the physics governing an ensemble of active particles and for the creation of numerical models capable of explaining the observed collective phenomena. In this work, we present ActiveNet, a machine-learning tool consisting of a graph neural network that uses the collective motion of particles to learn active and two-body forces controlling their individual dynamics. We verify our approach using numerical simulations of active Brownian particles, active particles undergoing underdamped Langevin dynamics, and chiral active Brownian particles considering different interaction potentials and values of activity. Interestingly, ActiveNet can equally learn conservative or nonconservative forces as well as torques. Moreover, ActiveNet has proven to be a useful tool to learn the stochastic contribution to the forces, enabling the estimation of the diffusion coefficients. Therefore, all coefficients of the equation of motion of Active Brownian Particles are captured. Finally, we apply ActiveNet to experiments of electrophoretic Janus particles, extracting the active and two-body forces controlling colloids' dynamics. On the one side, we have learned that the active force depends on the electric field and area fraction. On the other side, we have also discovered a dependence of the two-body interaction with the electric field that leads us to propose that the dominant force between active colloids is a screened electrostatic interaction with a constant length scale. We believe that the proposed methodological tool, ActiveNet, might open a new avenue for the study and modeling of experimental suspensions of active particles.

STOP-Bang questionnaire in patients hospitalized with acute symptomatic pulmonary embolism.

STUDY OBJECTIVES: The STOP-Bang questionnaire is a validated screening tool for obstructive sleep apnea (OSA). We conducted this study to validate it among patients hospitalized with acute symptomatic pulmonary embolism (PE). METHODS: This prospective cohort study enrolled consecutive stable patients with acute PE who underwent an overnight sleep study within 7 days after diagnosis. Our outcomes were: i) the STOP-Bang questionnaire's utility for risk stratification, ii) the discrimination of the STOP-Bang questionnaire categories, iii) the false negative rate of STOP-Bang questionnaire prediction, and iv) the clinical utility of the STOP-Bang questionnaire to exclude OSA. We also calculated the test performance characteristics to predict OSA. RESULTS: During the study period, 268 patients completed a sleep study. OSA was found in 47% of patients. OSA incidence in low-, moderate-, and high-risk STOP-Bang groups was 22.4%, 48.2%, and 61.5%, respectively (P <0.001). The area under the receiver operating characteristics curve of the STOP-Bang questionnaire for risk of OSA was 0.65. The false negative rate of a low-risk STOP-Bang questionnaire result to rule out OSA was 22.4% and the clinical utility was 21.6%. The sensitivity was 89.8% (97.2% for men and 80.4% for women). CONCLUSIONS: The STOP-Bang questionnaire showed poor discrimination for the risk of OSA in hospitalized patients with acute symptomatic PE. It had a high false negative rate and a low clinical utility. The STOP-Bang questionnaire had a good sensitivity in men, and might be used to rule out OSA in this population.

Closing the Sex-Based Differences in Stroke Care: Insights from a Large Telestroke Network on Treatment and Postacute Management.

Background: The evolution of ischemic stroke is different accordin'g to sex and is one of the main causes of death in women. Previous studies have shown that women are less likely to receive acute treatment, and stroke center type is an important predictor of door-to-needle times. We investigated whether women are attended in a similar way to men in the telestroke network with specialized stroke physicians. Methods: A prospective registry of ischemic strokes recorded in the centralized Andalusian telestroke network was analyzed, focusing on sex differences. Demographic data, clinical characteristics, neuroimaging data, treatment intervals, follow-up visits, and clinical outcomes were collected. Results: A total of 3009 suspected stroke patients were attended to in the telestroke network from 2019 to 2023, of which 42.74% were women. Women were older (p < 0.001) and less independent upon arrival (p = 0.006) than men. There was no difference in the treatment received or in the treatment time intervals between the groups. Importantly, there was no difference in modified Rankin scale scores at 3 months between sexes. At 3 months post-stroke follow-up, women had fewer imaging tests (p = 0.018) and fewer outpatient visits (p < 0.001) than men. Conclusions: No significant difference between men and women has been found in the acute treatment of stroke in a large telestroke network. However, the same is not true for the follow-up and management of patients after the acute phase. This fact supports that strict adherence to protocols and specialization of care lead to equal care that avoids sex differences in stroke treatment and functional outcomes.

Clinical outcomes of switching to adalimumab biosimilar (MSB11022) in patients with rheumatoid arthritis: RESTART Spanish Registry.

OBJECTIVE: MSB11022 is a biosimilar of adalimumab that has been shown comparable bioequivalence, safety, tolerability, and immunogenicity profiles to the reference adalimumab in healthy volunteers or in patients with psoriasis or rheumatoid arthritis (RA). This is the first study conducted under clinical practice conditions evaluating the switch from reference adalimumab to MSB11022 in patients with RA. METHODS: Retrospective and multicenter study with data from the medical records of patients with RA who switched from reference adalimumab or another biosimilar to MSB11022 and maintained this treatment for at least 6 months. Information registered comes from baseline visit, the moment of the switch, and the follow-up visits. RESULTS: Data from 86 patients were evaluated (median age 63.5 years, 75.6% female, 44.2% had erosive RA). Only 3.5% of the patients received biologic therapy prior to adalimumab. At baseline, median DAS28-CRP was 1.77 (80.2% in remission and 96.5% with low disease activity) and median CDAI was 4.00 (44.2% in remission and 90.7% with low disease activity). After a median follow-up of 8 months, median DAS28-CRP was 1.87 (86.0% in remission and 94.2% with low disease activity) and median CDAI was 4.00 (38.5% in remission and 95.3% with low disease activity). Only three patients experienced pain, swelling, and stinging at the injection site or a locally extensive hematoma in the area of administration. CONCLUSIONS: Adalimumab biosimilar MSB11022 maintained the efficacy benefits provided by previous adalimumab treatments with a safety profile in line with that already described for other biosimilars.

The impact of smoking on bronchiectasis and its comorbidities.

INTRODUCTION: Bronchiectasis, characterized by irreversible bronchial dilatation, is a growing global health concern with significant morbidity. This review delves into the intricate relationship between smoking and bronchiectasis, examining its epidemiology, pathophysiology, clinical manifestations, and therapeutic approaches. Our comprehensive literature search on PubMed utilized MESH terms including 'smoking,' 'smoking cessation,' 'bronchiectasis,' and 'comorbidities' to gather relevant studies. AREAS COVERED: This review emphasizes the role of smoking in bronchiectasis development and exacerbation by compromising airways and immune function. Interconnected comorbidities, including chronic obstructive pulmonary disease, asthma, and gastroesophageal reflux disease, create a detrimental cycle affecting patient outcomes. Despite limited studies on smoking cessation in bronchiectasis, the review stresses its importance. Advocating for tailored cessation programs, interventions like drainage, bronchodilators, and targeted antibiotics are crucial to disrupting the inflammatory-infection-widening cycle. EXPERT OPINION: The importance of smoking cessation in bronchiectasis management is paramount due to its extensive negative impact on related conditions. Proactive cessation programs utilizing technology and targeted education for high-risk groups aim to reduce smoking's impact on disease progression and related comorbidities. In conclusion, a personalized approach centered on smoking cessation is deemed vital for bronchiectasis, aiming to improve outcomes and enhance patients' quality of life in the face of this complex respiratory condition.

Effects of a pharmacist designed clinical decision support system on antimicrobial stewardship.

Background Clinical decision support systems (CDSS) are computer applications, which can be applied to give guidance to practitioners in antimicrobial stewardship (AS) activities, however, further information is needed for their optimal use. Objectives To analyze the implementation of a CDSS program in a primary-care hospital, describing alerts, recommendations, and the effect on consumption and clinical outcomes. Methods In October 2020, a pharmacist-driven CDSS designed for AS was implemented in a second-level hospital. The program provides a list of alerts related to antimicrobial treatment and microbiology, which were automatized for revision by the AS professionals. To analyze the implementation of the CDSS, a pre-post intervention, retrospective study was designed. AS triggered alerts and recommendations (total number and rate of acceptance) were compiled. The effect of the CDSS was measured using antimicrobial consumption, duration of antimicrobial treatments, in-hospital mortality and length of stay (LOS) for patients admitted for infectious causes. Results The AS team revised a total of 7,543 alerts and 772 patients had at least one recommendation, with an acceptance rate of 79.3%. Antimicrobial consumption decreased from 691.1 to 656.8 daily defined doses (DDD)/1,000 beds-month (P = 0.04) and the duration of antimicrobial treatment from 3.6 to 3.3 days (P <0.01). In-hospital mortality decreased from 6.6% to 6.2% (P=0.46) and mean LOS from 7.2 to 6.2 days (P<0.01) Conclusion The implementation of a CDSS resulted in a significant reduction of antimicrobial DDD, duration of antimicrobial treatments and hospital LOS. There was no significant difference in mortality.

A rare presentation of infective endocarditis: Phase 4 block of the left bundle branch as key for the diagnosis. A case report.

Definitive diagnosis of infective endocarditis (IE) is mainly based on microbiological and imaging criteria. In a minority of cases, particularly when perivalvular area is involved, cardiac conduction disorders (CCD) may appear, which implies worse prognosis. In this scenario, different degrees of auriculoventricular block can occur, but development of bundle branch block is rare. Herein, we present a case of IE with negative initial imaging tests, where the occurrence of phase 4 bundle branch block after a sequence of type I second degree AV block was crucial to establish a definitive diagnosis and an optimal therapeutic approach.

National record and analysis of pharmaceutical interventions in critical care units: PHARMACRITIC study. / Registro nacional y análisis de intervenciones farmacéuticas en unidades de cuidados críticos: estudio FARMACRITIC.

OBJECTIVE: To design a homogeneous methodology for the registration and analysis of pharmaceutical interventions performed in Spanish critical adults' care units. METHOD: Observational, prospective and multicenter study. In the first stage, a national registry of pharmaceutical interventions will be agreed upon and subsequently all the pharmaceutical interventions performed on adult patients admitted to Spanish CCUs during eight weeks will be recorded. Variables related to the type of CCU, the drug involved in the intervention, type of intervention (indication, effectiveness, safety), recommendation made by the pharmacist and the degree of acceptance will be evaluated. Risk and incidence will be calculated for each of the medication errors detected. The χ2-squared test or Fisher exact test will be used for categorical variables and Mann-Whitney U or Kruskal-Wallis test for continuous variables. All tests will be performed with a significance level α = 0.05 and confidence intervals with confidence 1- α. DISCUSSION: The results obtained from this project will make it possible to obtain a homogeneous classification of the pharmaceutical interventions performed in CCU, a national record and an evaluation of the weak points with the aim of developing strategies for improvement in the pharmaceutical care of the critically ill patient.

Dissection of the Genetic Basis of Genotype by Environment Interactions for Morphological Traits and Protein Content in Winter Wheat Panel Grown in Morocco and Spain.

To fulfill the growing demand for wheat consumption, it is important to focus on enhancement breeding strategies targeting key parameters such as yield, thousand kernel weight (TKW), quality characteristics including morphological traits, and protein content. These elements are key to the ongoing and future objectives of wheat breeding programs. Prioritizing these factors will effectively help meet the rising demand for wheat, especially given the challenges posed by unpredictable weather patterns. This study evaluated the morphological traits and protein content of 249 winter wheat varieties and advanced lines grown in eleven different environments in Morocco and Spain incorporating three varied sowing dates. The results showed considerable variability in morphological traits and protein content. Significant correlations were observed among various grain traits, with most grain morphological parameters exhibiting negative correlations with protein content. Differences across environments (p ≤ 0.01) in all traits, genotypes, and genotype by environment interaction were significant. A factorial regression analysis revealed significant impacts of environmental conditions on all grain morphological parameters, protein content, and TKW during the three growth stages. The study identified several high-performing and stable genotypes across diverse environments, providing valuable insights for wheat breeding programs such as genotypes 129, 234, 241, and 243. Genome-Wide Association Studies pinpointed 603 significant markers across 11 environments, spread across chromosomes. Among these, 400 markers were linked with at least two traits or observed in at least two different environments. Moreover, twelve marker-trait associations were detected that surpassed the Bonferroni correction threshold. These findings highlight the importance of targeted breeding efforts to enhance wheat quality and adaptability to different environmental conditions.

Antibacterial activity of gallic acid and methyl gallate against emerging non-fermenting bacilli.

Stenotrophomonas maltophilia, Achromobacter xylosoxidans, and Burkholderia cenocepacia are considered emerging pathogens classified as a public health problem due to extensive antimicrobial resistance. Therefore, the discovery of new therapeutic strategies has become crucial. This study aimed to evaluate the antimicrobial activity of gallic acid and methyl gallate against non-fermenting bacteria. The study included five clinical isolates of Stenotrophomonas maltophilia, Achromobacter xylosoxidans, and Burkholderia cenocepacia. The minimum inhibitory concentrations of gallic acid and methyl gallate were determined by the broth microdilution method. Growth curves, metabolic activity, and biofilm formation of each bacterial strain in the presence or absence of phenolic compounds were performed. Finally, the therapeutic efficacy of the compounds was evaluated using an in vivo model. Gallic acid and methyl gallate showed antibacterial activity against bacterial strains in a concentration range of 64 to 256 µg/mL, both compounds reduced bacterial growth and metabolic activity of the strains, even at subinhibitory concentrations. Only, methyl gallate exhibited activity to inhibit the formation of bacterial biofilms. Moreover, gallic acid and methyl gallate increased larval survival by up to 60% compared to 30% survival of untreated larvae in a bacterial infection model in Galleria mellonella. Our results highlight the potential of gallic acid and methyl gallate as therapeutic alternatives for infections by emerging non-fermentative bacteria.

Immediate Versus Deferred Systemic Therapy in Patients With Mesothelioma.

BACKGROUND: The 2018 ASCO pleural mesothelioma (PM) treatment guideline states that "a trial of expectant observation may be offered" in patients with asymptomatic inoperable epithelioid mesothelioma with low disease burden. The aim of our analysis was to evaluate clinical characteristics and outcomes in PM-patients managed with initial observation and deferred treatment initiation. METHODS: We retrospectively collected clinicodemograhic and outcome data of patients with inoperable PM. Patients were assigned to 2 treatment decision groups: decision to start immediate systemic treatment (Immediate Treatment Group) versus observation and deferring treatment (Deferred Treatment group). RESULTS: Of 222 patients with advanced PM, systemic treatment was started immediately in the majority of patients (189, 85%; immediate group); treatment was deferred in 33 (15%) patients (deferred group); systemic therapy was chemotherapy-based in 91% and 79% respectively. Patients in the deferred group were older (70 vs 67 years, p = .05), less likely to have stage IV disease (28% vs. 51%, p = .08) and more often had epithelioid histology (90% vs. 70%, p = .03). Nineteen patients (58%) in the deferred group eventually received treatment. With a median follow-up time of 10.9 months median overall survival (OS) in the entire cohort was 12.4 months and was significantly longer in the deferred group (20.6 months vs. 11.5 months, p = .02). No difference in median progression-free survival (PFS) in first-line treatment between groups was seen (5.4 and 5.3 months). CONCLUSION: This real-world analysis suggests that deferral of systemic therapy and close observation may not impact OS or physician-assessed PFS in selected PM-patients.

Medium-Term Disability and Long-Term Functional Impairment Persistence in Survivors of Severe COVID-19 ARDS: Clinical and Physiological Insights.

BACKGROUND: Although the medium- and long-term sequelae of survivor of acute respiratory distress syndrome (ARDS) of any cause have been documented, little is known about the way in which COVID-19-induced ARDS affects functional disability and exercise components. Our aims were to examine the medium-term disability in severe COVID-19-associated ARDS survivors, delineate pathophysiological changes contributing to their exercise intolerance, and explore its utility in predicting long-term functional impairment persistence. METHODS: We studied 108 consecutive subjects with severe COVID-19 ARDS who remained alive 6 months after intensive care unit (ICU) discharge. Lung morphology was assessed with chest non-contrast CT scans and CT angiography. Functional evaluation included spirometry, plethysmography, muscle strength, and diffusion capacity, with assessment of gas exchange components through diffusing capacity of nitric oxide. Disability was assessed through an incremental exercise test, and measurements were repeated 12 and 24 months later in patients with functional impairments. RESULTS: At 6 months after ICU discharge, a notable dissociation between morphological and clinical-functional sequelae was identified. Moderate-severe disability was present in 47% of patients and these subjects had greater limitation of ventilatory mechanics and gas exchange, as well as greater symptomatic perception during exercise and a probable associated cardiac limitation. Female sex, hypothyroidism, reduced membrane diffusion component, lower functional residual capacity, and high-attenuation lung volume were independently associated with the presence of moderate-severe functional disability, which in turn was related to higher frequency and greater intensity of dyspnea and worse quality of life. Out of the 71 patients with reduced lung volumes or diffusion capacity at 6 months post-ICU discharge, only 19 maintained a restrictive disorder associated with gas exchange impairment at 24 months post-discharge. In these patients, 6-month values for diffusion membrane component, maximal oxygen uptake, ventilatory equivalent for CO2, and dead space to tidal volume ratio were identified as independent risk factors for persistence of long-term functional sequelae. CONCLUSIONS: Less than half of survivors of COVID-19 ARDS have moderate-severe disability in the medium term, identifying several risk factors. In turn, diffusion membrane component and exercise tolerance at 6-month ICU discharge are independently associated with the persistence of long-term functional sequelae.

Genetic control of root architectural traits under drought stress in spring barley (Hordeum vulgare L.).

Root architectural traits play pivotal roles in plant adaptation to drought stress, and hence they are considered promising targets in breeding programs. Here, we phenotyped eight root architecture traits in response to well-watered and drought stress conditions in 200 spring barley (Hordeum vulgare L.) inbred lines over two consecutive field seasons. Root architecture traits were less developed under drought in both seasons when compared with control treatments. Genetic variation in root architectural traits was dissected employing a genome-wide association study (GWAS) coupled with linkage disequilibrium mapping. GWAS uncovered a total of 186 significant single nucleotide polymorphism-trait associations for eight root traits under control, drought, and drought-related indices. Of these, a few loci for root traits were detected on chromosomes 3 and 5, which co-located with QTL identified in previous studies. Interestingly, 13 loci showed simultaneou associations with multiple root traits under drought and drought-related indices. These loci harbored candidate genes, which included a wide range of drought-responsive components such as transcription factors, binding proteins, protein kinases, nutrient and ion transporters, and stress signaling factors. For instance, two candidate genes, HORVU7Hr3G0713160 and HORVU6H r3G0626550, are orthologous to AtACX3 and AtVAMPs, which have reported functions in root length-mediated drought tolerance and as a key protein in abiotic stress tolerance, respectively. Interestingly, one of these loci underlying a high-confidence candidate gene NEW ENHANCER OF ROOT DWARFISM1 (NERD1) showed involvement with root development. An allelic variation of this locus in non-coding region was significantly associated with increased root length under drought. Collectively, these results offer promising multi-trait affecting loci and candidate genes underlying root phenotypic responses to drought stress, which may provide valuable resources for genetic improvement of drought tolerance in barley.

Presymptomatic Testing for Huntington's Disease in Mexico: 28 Years of Experience.

INTRODUCTION: Huntington's disease (HD) is a genetic neurodegenerative disorder with dominant inheritance. Our center in Mexico City has offered presymptomatic testing (PT) since 1995. OBJECTIVE: To describe the main clinical and demographic characteristics of at-risk HD individuals who applied to the PT program, the reasons for seeking it, and the molecular results. METHODS: A cross-sectional study was conducted with sociodemographic and clinical data of all PT applicants from 1995-2023. Reasons for seeking PT were assessed using a modified questionnaire. In addition, anxiety, and depressive symptoms before and after PT were evaluated with Beck's instruments; cognitive impairment (CI) was assessed with the Mini-Mental State Examination (MMSE) and molecular results. RESULTS: 214 people applied for PT (2.1% of the at-risk population identified in our center); 63% were women (mean age of 37.11 years). 204 (95.3%) were accepted and 190 received results. 70% indicated that the main reason for applying for PT was to inform their offspring about the risk of inheriting HD. Significant differences were observed in the reasons for seeking PT by age group. Although some subjects received treatment, Beck's instrument scores did not indicate special attention or pharmacological treatment. The MMSE showed probable CI in 20 subjects. Of those who received results, 37% were carriers of a full penetrance allele. CONCLUSION: Our center has the only formal PT program for HD in Mexico. The reasons for seeking PT are varied and age-related. Although PT is offered to all subjects at risk for HD, uptake remains low.

The relationships between fear of missing out and psychological and sociocultural factors in Latinx emerging adult college students.

OBJECTIVES: The proliferation of social media has resulted in negative consequences such as fear of missing out (FoMO), the anxious feelings one has when others are having rewarding experiences. Few studies have assessed FoMO in Latinx emerging adult college students, none utilizing the socioecological framework. This study assessed the relationships between FoMO and psychological and sociocultural risk and protective factors. METHOD: Latinx college students (n = 452; Mage = 19.97 years, SD = 1.89; 77.2% female) completed an online survey assessing demographics, FoMO, social media addiction, depression, anxiety, stress, Machiavellianism, narcissism, psychopathy, familism, and acculturation. Two multiple linear regressions assessed the associations between FoMO and psychological and sociocultural factors. RESULTS: Both regressions were statistically significant. First, FoMO was positively associated with social media addiction, depression, and Machiavellianism. Second, FoMO was positively associated with familial honor and negatively associated with familial interconnectedness and ethnic social relations. CONCLUSIONS: Associations between FoMO and psychological factors are consistent with past literature, yet they highlight the need for prospective studies to assess temporality. The fact that FoMO was related uniquely to familistic attitudes suggests the importance of family in FoMO perceptions and the need to assess these associations in a more nuanced manner.
