Through various social media platforms, individuals learn, discuss, and describe their thoughts and opinions regarding mental health, which may influence how society interacts with mental health topics and services. TikTok is one of the more recent social media platforms to house a wide array of video content regarding mental health attitudes, symptoms, humor, and advice, which are all regularly absorbed and shared by individuals globally. The present study explored the influence of TikTok videos posted by non-mental health professionals on attitudes toward mental health stigma, self-pathologizing, and professional mental health treatment-seeking in a college sample with ages ranging from 18 to 60 (M = 21.20, SD = 6.26). In a pre-post randomized-control design, participants completed dependent variable measures before and after viewing daily, brief mental health-related TikTok videos (experimental group) or non-mental health-related TikTok videos (control group) over two weeks. The results indicated that those who viewed mental health TikToks did not experience the increase in mental health stigma observed in the control group (p < .01), suggesting that mental health TikTok content may suppress increases in mental health stigma over time through exposure to mental health topics. However, the experimental group did not experience the decrease in self-stigma observed in the control group (p = .04). Further, TikTok content did not significantly impact perceptions of public stigma, treatment-seeking, or self-pathologizing. These results suggest that mental health social media content may be protective against some stigmatized beliefs, but it may not significantly impact perceptions of self and public stigma, treatment-seeking attitudes, or self-pathologizing.

PurposeAn individual’s location of residence may impact health, however, health services and outcomes research generally use a single point in time to define where an individual resides. While this estimate of residence becomes inaccurate when the study subject moves, the impact on observed associations is not known. This study quantifies the impact of different methods to define residence (rural, urban, metropolitan) on the association with all-cause mortality.MethodsA diabetes cohort of new metformin users was identified from administrative data in Alberta, Canada between 2008 and 2019. An individual’s residence (rural/urban/metropolitan) was defined from postal codes using 4 different methods: residence defined at 1-year before first metformin (this served as the reference model), comparison 1- stable residence for 3 years before first metformin, comparison 2– residence as time-varying (during the outcome observation window), and comparison 3 - nested case control (residence closest to the index date after identifying cases and controls). Multivariable Cox proportional hazard and logistic regression models were constructed to examine the association between residence definitions and all-cause mortality.ResultsWe identified 157,146 new metformin users (mean age of 55 years and 57% male) and 8,444 (5%) deaths occurred during the mean follow up of 4.7 (SD 2.3) years. There were few instances of moving after first metformin; 2.6% of individuals moved to a smaller centre (metropolitan to urban or rural, or urban to rural) and 3.1% moved to a larger centre (rural to urban or metropolitan, or urban to metropolitan). The association between rural residence and all-cause mortality was consistent (aHR:1.18; 95%CI:1.12–1.24), regardless of the method used to define residence.ConclusionsThe method used to define residence in a population of adults newly treated with metformin for type 2 diabetes has minimal impact on measures of all-cause mortality, possibly due to infrequent migration. The observed association between residence and mortality is compelling but requires further investigation and more robust analysis.

We investigated and compared mortality rates and risk factors for pre-pandemic and pandemic all-cause mortality in a population-based cohort of men and women in Arkhangelsk, Russia. A prospective cohort study enrolled 2,324 participants aged 35 to 69 years between 2015 and 2017. All participants were followed up for all-cause deaths using the mortality registry. Mortality rates per 1000 person-years were calculated for men and women in the pre-pandemic and pandemic periods. Cox regression models were used to investigate demographic, lifestyle, and health characteristics associated with increased risk of death in both periods. During the pandemic, age-standardized all-cause mortality increased in women, but minor change was observed in men. Older age, smoking, and diabetes were associated with a higher risk of all-cause death in both periods and for both sexes. In women, higher risk during the pandemic was associated with obesity, angina, elevated cystatin C levels, and a history of COVID-19. In men, asthma and elevated hs-Troponin T levels increased the risk of death during the pandemic, while elevated hs-CRP and NT-proBNP levels were associated with higher risk in both periods. Targeted preventive interventions for men and women with specific risk factors can be implemented during potential future infectious disease outbreaks.

Despite retailers’ interest in moving away from thin-model photography to embrace body-size diversity, online fashion shopping predominantly features thin models. While concerns about negative consequences for sales impede industry-wide changes, we demonstrate that consumers and retailers benefit from optimally portraying diverse bodies. Three studies unveil the “Dissimilarity-Risk Deterrence Effect,” wherein thin models dissuade consumers with larger clothing sizes from online purchasing due to perceived body-size dissimilarity and heightened fit-risk perception. Eight experiments demonstrate that models of consumers’ own size mitigate the effect, enhancing online purchase decisions, while controlling for mechanisms like positive affect, authenticity and social identification. The effect extends across various clothing items but attenuates when body size matters less to fit evaluation. Moreover, the effect is concealed by retailers’ risk-reducing strategies, such as measurement information and free product return policies. This research underscores the strategic significance of diverse product imaging to improve supply chain efficiency and consumer well-being.

BackgroundFibroblast-like synoviocytes (FLSs) are involved in osteoarthritis (OA) pathogenesis through pro-inflammatory cytokine production. TAK-242, a TLR4 blocker, has been found to have a significant impact on the gene expression profile of pro-inflammatory cytokines such as IL1-β, IL-6, TNF-α, and TLR4, as well as the phosphorylation of Ikβα, a regulator of the NF-κB signaling pathway, in OA-FLSs. This study aims to investigate this effect because TLR4 plays a crucial role in inflammatory responses.Materials and methodsTen OA patients’ synovial tissues were acquired, and isolated FLSs were cultured in DMEM in order to assess the effectiveness of TAK-242. The treated FLSs with TAK-242 and Lipopolysaccharides (LPS) were analyzed for the mRNA expression level of IL1-β, IL-6, TNF-α, and TLR4 levels by Real-Time PCR. Besides, we used western blot to assess the protein levels of Ikβα and pIkβα.ResultsThe results represented that TAK-242 effectively suppressed the gene expression of inflammatory cytokines IL1-β, IL-6, TNF-α, and TLR4 which were overexpressed upon LPS treatment. Additionally, TAK-242 inhibited the phosphorylation of Ikβα which was increased by LPS treatment.ConclusionAccording to our results, TAK-242 shows promising inhibitory effects on TLR4-mediated inflammatory responses in OA-FLSs by targeting the NF-κB pathway. TLR4 inhibitors, such as TAK-242, may be useful therapeutic agents to reduce inflammation and its associated complications in OA patients, since traditional and biological treatments may not be adequate for all of them.

The Positive Outcomes With Emotion Regulation (POWER) Program is a transdiagnostic intervention for adolescents at risk of developing emotional disorders. The POWER Program was designed to be implemented in secondary schools, by school personnel with or without specialized mental health training, as a Tier 2 intervention. In this pilot study, the POWER Program was implemented by school psychologists and school psychologists-in-training and evaluated across four focal student participants using a multiple-baseline-across-participants single-case design. Program efficacy was assessed using systematic direct classroom observations of student negative affect and social engagement as well as student and caregiver ratings of emotional and behavioral symptoms. Program usability was assessed through rating scales completed by intervention facilitators and student participants. Overall, results provide evidence of the POWER Program’s small- to large-sized effects on students’ emotional and behavioral functioning as observed in the classroom and self-reported by students. In addition, results suggest implementation facilitators’ and students’ positive impressions of the program, evident in ratings of high understanding, feasibility, and acceptability across groups. Study limitations are highlighted with attention to opportunities to further refine and evaluate the POWER Program.

BackgroundOcular complaints, including acute or subacute vision loss, are commonly encountered in emergency departments (ED). These potentially time-sensitive complaints are difficult to diagnose and evaluate without adequate, specialized equipment and expertise. Additionally, a thorough evaluation often requires a more extensive and specialized physical exam, imaging, and ophthalmologic consultation, all of which may not be readily available in the acute setting.Case presentationThis case report presented a patient in the emergency department with the chief complaint of vision loss. Point-of-care ultrasound (POCUS) using the 10-MHz-linear-array probe, in the ocular setting, demonstrated calcification of the lens, a finding consistent with cataract in the right eye.ConclusionsThe use of POCUS can expedite the accurate identification of vision threatening pathology, such as cataracts, and streamline ED disposition and plan of care.

Microdeletions at 1q43-q44 have been described as resulting in a clinically recognizable phenotype of intellectual disability (ID), facial dysmorphisms and microcephaly (MIC). In contrast, the reciprocal microduplications of 1q43-q44 region have been less frequently reported and patients showed a variable phenotype, including macrocephaly. Reports of a large number of patients with copy number variations involving this region highlighted the AKT3 gene as a likely key player in head size anomalies. We report four novel patients with copy number variations in the 1q43-q44 region: one with a larger deletion (3.7Mb), two with smaller deletions affecting AKT3 and SDCCAG8 genes (0.16 and 0.18Mb) and one with a quadruplication (1Mb) that affects the entire AKT3 gene. All patients with deletions presented MIC without structural brain abnormalities, whereas the patient with quadruplication had macrocephaly, but his carrier father had normal head circumference. Our report also includes a comparison of phenotypes in cases with 1q43-q44 duplications to assist future genotype-phenotype correlations. Our observations implicate AKT3 as a contributor to ID/development delay (DD) and head size but raise doubts about its straightforward impact on the latter aspect of the phenotype in patients with 1q43-q44 deletion/duplication syndrome.

Grain sorghum is an important cereal crop for both human food, animal feed, and biofuel production in the United States. A diverse set of 19 grain sorghum genotypes was grown in three locations in Kansas to evaluate the genotype, location, and genotype × location effect on grain quality attributes. The physical characteristics of the grain (size and hardness) were greatly affected by genotype, location, and their interaction. The chemical components and functional properties were affected by genotype and location. The amylose content varied from 19.2 to 30.7% and was variable due to growing location. The starch granule size distribution exhibited little variation due to location, but was affected by the genotype. Protein content ranged from 11.1 to 15.2% and digestibility ranged from 45.6 to 62.1% due to genotype. The small amount of interaction between genotype and location for the protein content and digestibility allows for selection of the desired genotype and location without a wide variation due to their combination. Among the nine traits studied, maximum variation was explained by kernel diameter (20.0%), followed by kernel weight (19.3%), ash (14.6%) and protein content (LECO) (10.8%). Principal component analysis identified SC628, SC489, SC1104 and BTx399 with good and SC391 and SC11277 with poor grain quality. The diverse set of grain sorghum genotypes and variation in growth conditions led to differences in both the physical and chemical components in the grain. Thus, the variation due to genotype and location will allow for the ability to select the most desirable trait at a specific location.

Irrigation of food and fiber crops worldwide continues to increase. Nitrogen (N) from fertilizers is a major source of the potent greenhouse gas nitrous oxide (NO) in irrigated cropping systems. Nitrous oxide emissions data are scarce for crops in the arid western United States. The objective of these studies was to assess the effect of N fertilizer management on NO emissions from furrow-irrigated, overhead sprinkler-irrigated, and subsurface drip-irrigated cotton ( L.) in Maricopa, AZ, on Trix and Casa Grande sandy clay loam soils. Soil test- and canopy-reflectance-based N fertilizer management were compared. In the furrow- and overhead sprinkler-irrigated fields, we also tested the enhanced efficiency N fertilizer additive Agrotain Plus as a NO mitigation tool. Nitrogen fertilizer rates as liquid urea ammonium nitrate ranged from 0 to 233 kg N ha. Two applications of N fertilizer were made with furrow irrigation, three applications under overhead sprinkler irrigation, and 24 fertigations with subsurface drip irrigation. Emissions were measured weekly from May through August with 1-L vented chambers. NO emissions were not agronomically significant, but increased as much as 16-fold following N fertilizer addition compared to zero-N controls. Emission factors ranged from 0.10 to 0.54% of added N fertilizer emitted as NO-N with furrow irrigation, 0.15 to 1.1% with overhead sprinkler irrigation, and <0.1% with subsurface drip irrigation. The reduction of NO emissions due to addition of Agrotain Plus to urea ammonium nitrate was inconsistent. This study provides unique data on NO emissions in arid-land irrigated cotton and illustrates the advantage of subsurface drip irrigation as a low NO source system.
