ABSTRACT

INTRODUCTION: Childhood obesity has been associated with numerous poor health conditions, with geographic disparities demonstrated. Limited research has examined the association between rurality and food security, physical activity, and overweight or obesity among children. We examined rates of food security, physical inactivity, and overweight or obesity among rural and urban children and adolescents, and associations between rurality and these 3 outcomes.

METHODS: We used cross-sectional data from a nationally representative sample of children and adolescents aged 10 to 17 years from the 2019-2020 National Survey of Children’s Health (N = 23,199). We calculated frequencies, proportions, and unadjusted associations for each variable by using descriptive statistics and bivariate analyses. We used multivariable logistic regression models to examine the association between rurality and food security, physical activity, and overweight or obesity.

RESULTS: After adjusting for sociodemographic factors, rural children and adolescents had higher odds than urban children and adolescents of being overweight or obese (adjusted odds ratio = 1.30; 95% CI, 1.11-1.52); associations between rurality and physical inactivity and food insecurity were not significant.

CONCLUSION: The information from this study is timely for policy makers and community partners to make informed decisions on the allocation of healthy weight and obesity prevention programs for children and adolescents in rural settings. Our study provides information for public health programming and the designing of appropriate dietary and physical activity interventions needed to reduce disparities in obesity prevention among children and adolescents.

ABSTRACT

BACKGROUND: Attention deficit/hyperactivity disorder (ADHD) is a highly prevalent childhood disorder. Maternal smoking during pregnancy is a replicated environmental risk factor for this disorder. It is also a robust modifier of gene methylation during the prenatal developmental period. In this study, we sought to identify loci differentially methylated by maternal smoking during pregnancy and relate their methylation levels to various behavioural and physical outcomes relevant to ADHD.

METHODS: We extracted DNA from blood samples from children diagnosed with ADHD and deeply phenotyped. Genome-wide DNA methylation was assessed using Infinium MethylationEPIC BeadChip. Maternal smoking during pregnancy was self-declared and assessed retrospectively.

RESULTS: Our sample included 231 children with ADHD. Statistically significant differences in DNA methylation between children exposed or not to maternal smoking during pregnancy were detected in 3457 CpGs. We kept 30 CpGs with at least 5% of methylation difference between the 2 groups for further analysis. Six genes were associated with varied phenotypes of clinical relevance to ADHD. The levels of DNA methylation in RUNX1 were positively correlated with the CBCL scores, and DNA methylation in MYO1G correlated positively with the score at the Conners rating scale. Methylation level in a CpG located in GFI1 correlated with birthweight, a risk factor for ADHD. Differentially methylated regions were also identified and confirmed the association of RUNX1 methylation levels with the CBCL score.

LIMITATIONS: The study has several limitations, including the retrospective recall with self-report of maternal smoking during pregnancy as well as the grouping of individuals of varying age and developmental stage and of both males and females. In addition, the correlation design prevents the building of causation models.

CONCLUSION: This study provides evidence for the association between the level of methylation at specific loci and quantitative dimensions highly relevant for ADHD as well as birth weight, a measure that has already been associated with increased risk for ADHD. Our results provide further support to public health educational initiatives to stop maternal smoking during pregnancy.

ABSTRACT

BACKGROUND: Human navigation of social interactions relies on the processing of emotion on faces. This meta-analysis aimed to produce an updated brain atlas of emotional face processing from whole-brain studies based on a single emotional face-viewing paradigm (PROSPERO CRD42022251548).

METHODS: We conducted a systematic literature search of Embase, MEDLINE and PsycINFO from May 2008 to October 2021. We used seed-based d mapping with permutation of subject images to conduct a quantitative meta-analysis of functional neuroimaging contrasts between emotional (e.g., angry, happy) and neutral faces. We conducted agglomerative hierarchical clustering of meta-analytic map contrasts of emotional faces relative to neutral faces. We investigated lateralization of emotional face processing.

RESULTS: From 5549 studies identified, 55 data sets (1489 healthy participants) met our inclusion criteria. Relative to neutral faces, we found extensive activation clusters by fearful faces in the right inferior temporal gyrus, right fusiform area, left putamen and amygdala, right parahippocampalgyrus and cerebellum; we found smaller activation clusters by angry faces in the right cerebellum and right middle temporal gyrus (MTG) and by disgusted faces in the left MTG. Happy and sad faces did not reach statistical significance. Clustering analyses showed similar activation patterns of fearful and angry faces; activation patterns of happy and sad faces showed the least correlation with other emotional faces. Emotional face processing was predominantly left-lateralized in the amygdala and anterior insula, and right-lateralized in the ventromedial prefrontal cortex.

LIMITATIONS: Reliance on discretized effect sizes based on peak coordinate location instead of statistical brain maps, and the varying level of statistical threshold reporting from original studies, could lead to underdetection of smaller clusters of activation.

CONCLUSION: Processing of emotional faces appeared to be oriented toward identifying threats on faces, from highest (i.e., angry or fearful faces) to lowest level (i.e., happy or sad faces), with a more complex lateralization pattern than previously theorized. Emotional faces may be processed in latent grouping but organized by threat content rather than emotional valence.

ABSTRACT

INTRODUCTION: gonarthrosis is a degenerative disease, whose loss of cartilage causes changes in the adjacent bone and its response produces deformations and attempts at regeneration. In 1934 Meyer and Palmer isolated bovine vitreous humor, a polysaccharide called hyaluronic acid, which has the property of visco-elasticity. Today, multiple procedures performed in orthopedics are known, in order to limit the degenerative process that this entails.

OBJECTIVE: to know the use and efficacy of hyaluronic acid in the patient requiring knee arthroscopy, evaluating the evolution of the patient using the WOMAC scale; as well as the ideal time of application of hyaluronic acid in this study group.

MATERIAL AND METHODS: clinical, non-randomized, prospective, analytical trial. 48 patients from 45 to 60 years of age, divided into 3 groups with a diagnosis of gonarthrosis grade II-III, who underwent arthroscopy with subsequent hyaluronic acid application, were evaluated; in the postoperative period (group 1), one month after the postoperative period (group 2) and without application (group 3) in a period from September 2015 to June 2016 at the ISSSTE Hospital “Dr. Darío Fernández Fierro”.

RESULTS: the treatment showed differences in patients regarding reduction of pain and stiffness; and improvement in functional capacity.

CONCLUSION: despite, there are no conclusive results if the treatment is better than the other, certain data suggests that using hyaluronic acid in the postoperative improves rigidity and function, however, it was not statistically significant.

ABSTRACT

INTRODUCTION: osteoarthritis is one of the most prevalent chronic diseases in the world and is defined as the gradual loss of cartilage in the joints, mainly that of the knee. It is considered a cause of disability in older adults and is characterized by pain, stiffness and loss of mobility.

MATERIAL AND METHODS: observational study to evaluate the effect of the combination of non-hydrolyzed type II native collagen (CII-NH), omega-3 (Om-3) and astaxanthin (AX), in a population of 182 patients with knee osteoarthritis grade I/II. Measurements of thigh circumference, arcs of movement and pain were obtained through international scales such as the visual analogue pain scale (VAS), the Lequesne index and the Western Ontario McMaster Universities Osteoarthritis Index (WOMAC) scale. Medical check-ups were performed every 30 days for three months. The Statgraphics software (Statgraphics Technologies, Virginia) was used, the evaluation of the variables and the statistical significance were determined by t Student test and the results are shown as a mean.

RESULTS: it was shown that daily consumption increases mobility, decreases knee pain and inflammation in patients within three months. Additionally, there was a reduction in the consumption of nonsteroidal anti-inflammatory drugs (NSAIDs) by the study subjects.

CONCLUSION: the fixed combination of non-hydrolyzed type II collagen, omega-3 and astaxanthin, generates, in the short term, a decrease in inflammation and stiffness in patients with osteoarthritis.

ABSTRACT

INTRODUCTION: total knee arthroplasty has gained popularity over decreasing pain, restoring mobility and improving patients’ quality of life. At the institutional level, there is no multidisciplinary model in the treatment of our patients, and in our environment, physical rehabilitation starts late, making it difficult for patients to reincorporate and attain adequate pain control.

MATERIAL AND METHODS: a controlled, randomized, prospective and longitudinal study was conducted, 55 patients underwent total knee arthroplasty, assigned to two study groups: the ERAS (enhanced recovery after surgery) group (n = 27) and the usual group (n = 28). Inclusion criteria were patients with Kellgren-Lawrence classification grade 4 gonarthrosis, age between 30-70 years and follow-up for six months. Descriptive statistics were performed using medians and interquartile range, while inferential statistics were performed using the Kruskal-Wallis test.

RESULTS: the results obtained at six months showed no statistically significant differences in age (p = 0.327) and gender (p = 0.588). The results obtained in the scales of VAS, WOMAC and IKDC showed statistically significant difference (p = 0.000). The rapid recovery group with a 120° flexion median and the usual group with 90° flexion, both groups with 0° extension.

CONCLUSIONS: the enhanced recovery after surgery pathway in joint replacement procedures showed good results on pain, function, mobility and complications compared to patients undergoing usual management.

ABSTRACT

INTRODUCTION: in patients with anterior glenohumeral (GH) instability together with an off-track or engaging Hill-Sachs (HS) defect, Bankart-remplissage (B-R) surgery reduces the recurrence rate when compared to Bankart (B) surgery alone. There is controversy regarding whether the recurrence rate also decreases in patients with on-track or non-engaging Hill-Sachs defects.

OBJECTIVE: to compare the recurrence rate and clinical evolution of patients with anterior glenohumeral instability with ‘on-track’ Hill-Sachs defect treated with either B or B-R surgery.

MATERIAL AND METHODS: non-randomized, retrospective, single-center cohort study of patients with anterior glenohumeral instability and on-track Hill-Sachs defect, operated between January 2010 and December 2018. Patients operated with B versus B-R were compared. Recurrence, complications and re-operation were recorded. In addition, VAS, SSV, WOSI and qDASH scores were obtained and compared in both groups.

RESULTS: of the 105 patients who met the inclusion criteria, 78 (74.3%) patients had a complete follow-up (52 B and 26 B-R, 4.3 years median follow-up). There was a higher recurrence rate in group B compared to B-R, with this difference not reaching statistical significance (17.3% vs 7.7%, p = 0.21). There were no significant differences in residual pain, feeling of instability, complications or VAS, qDASH, SSV or WOSI scores between both groups. In the subgroup analysis, patients who practiced contact sports and were operated with B showed higher recurrence rates (24.1% vs 0%, p = 0.08) and complications (41.4% vs 18.2%, p = 0.16) when compared to B + R, although these differences were not significant.

CONCLUSION: there were no significant differences in recurrence rates and functional evolution between patients with anterior glenohumeral instability operated with B or B-R surgery. Comparative, prospective studies should be performed to establish definitive recommendations.

ABSTRACT

Allogeneic haematopoietic stem cell transplantation (HCT) is the curative treatment for myelodysplastic syndrome with a complex karyotype (CK-MDS). However, only a few studies have been limited to patients with CK-MDS undergoing allogeneic HCT. This study aimed to identify the risk factors for patients with CK-MDS undergoing allogeneic HCT. We included 691 patients with CK-MDS who received their first allogeneic HCT. The overall survival (OS) was the primary end-point, estimated using the Kaplan-Meier method. Prognostic factors were identified using a Cox proportional hazards model. The 3-year OS was 29.8% (95% confidence interval [CI]: 26.3-33.3). In the multivariable analysis, older age (hazard ratio [HR]: 1.44, 95% CI: 1.11-1.88), male sex (HR: 1.38, 95% CI: 1.11-1.71), poor haematopoietic cell transplant comorbidity index (HR: 1.47, 95% CI: 1.20-1.81), red blood cell transfusion requirement (HR: 1.58, 95% CI: 1.13-2.20), platelet transfusion requirement (HR: 1.85, 95% CI: 1.46-2.35), not-complete remission (HR: 1.55, 95% CI: 1.16-2.06), a high number of karyotype abnormality (HR: 1.63, 95% CI: 1.18-2.25) and monosomal karyotype (HR: 1.49, 95% CI: 1.05-2.12) were significantly associated with OS. Thus, the 3-year OS of allogeneic HCT was 29.8% in patients with CK-MDS, and we identified risk factors associated with poor OS.

ABSTRACT

BACKGROUND AND OBJECTIVES: : Visually induced motion sickness (VIMS) is a phenomenon similar to motion sickness frequently observed in users of visual technologies. The Visually Induced Motion Sickness Susceptibility Questionnaire (VIMSSQ), developed by Golding et al. (2006), is considered the most effective scale for assessing VIMS susceptibility levels. The main purpose of this study was to standardize the selection of participants for research conducted with virtual reality, especially motion sickness (MS) research. To achieve this, first, the Turkish version of the VIMSSQ was created to establish its validity and reliability, and subsequently, its correlation with the Turkish Motion Sickness Susceptibility Questionnaire Short form (HDDA), the expanded version of the Motion Sickness Susceptibility Questionnaire Short form (MSSQ), was examined.

SUBJECTS AND METHODS: : Linguistic equivalence assessment was obtained from ten experts by passing the VIMSSQ through the translation process. The VIMSSQ and the Turkish MSSQ forms were then administered to 49 subjects. This study statistically analyzed the validity and reliability of the VIMSSQ and its relationship with the MSSQ.

RESULTS: : Results showed that the Turkish version of the original questionnaire is highly reliable (Cronbach alpha=0.843). There is a moderate statistically significant positive correlation between the total MSSQ scores and the subfactors of the VIMSSQ.

CONCLUSIONS: : In this study, VIMSSQ was successfully adapted to Turkish, normative data demonstrated its validity, and all sub-factors were highly reliable. The Turkish version of the VIMSSQ can serve as a valuable tool for estimating individual susceptibility to VIMS.

ABSTRACT

We compare the impact of the first two waves of the COVID-19 pandemic on risk of age-standardized mortality by sex, UK country, and English region. Each wave is defined as lasting 26 weeks and are consecutive beginning in 2020 week 11. The expected rate is estimated from 2015 to 2019 mean and the projected mortality trend from the same period are used to estimate excess mortality. By both measures, excess mortality was highest and lowest in regions of England, London and the South-West, respectively. Excess mortality was consistently higher for males than females.
