Survey of South Carolina Public School Personnel Perspectives on Barriers and Facilitators to Regular Physical Activity and Healthy Eating Behaviors in Schools

J Sch Health. 2022 Aug 13. doi: 10.1111/josh.13228. Online ahead of print.

ABSTRACT

BACKGROUND: In South Carolina (SC), 42% of youth are overweight or obese. Two sets of modifiable behaviors contributing to obesity are physical activity (PA) and dietary habits. School-based interventions have successfully improved these behaviors. The purpose of this study was to identify SC public school personnel perspectives on the most common barriers and facilitators to regular PA and healthy eating behaviors in schools.

METHODS: A needs assessment survey was conducted with school personnel statewide. There were 17 questions on the survey that addressed: (1) demographic information about participants’ educational backgrounds, (2) barriers to regular PA and healthy eating behaviors in schools, and (3) facilitators to regular PA and healthy eating behaviors in schools. Univariate and bivariate descriptive statistical analyses were performed using IBM SPSS Statistics 27.

RESULTS: Participants (N = 1311) indicated insufficient time for regular PA (n = 514, 39.2%) and limited access to healthy foods for healthy eating (n = 271, 20.7%) as main barriers. The primary facilitators were support from administrators for regular PA (n = 264, 20.1%) and support from cafeteria staff for healthy eating (n = 234, 17.8%). Further analyses explored how factors compared based on roles in schools, academic levels, and school district classifications.

CONCLUSIONS: Results suggest that overarching barriers and facilitators to school-based interventions addressing childhood obesity exist, so common strategies to mitigate challenges and maximize supports can be used in schools. Future studies are needed to examine how decreasing barriers and enhancing facilitators affect the implementation and outcomes of these school-based interventions.

Clinical presentation of bacille Calmette-Guérin (BCG) infections after BCG instillation therapy

BJU Int. 2022 Aug 13. doi: 10.1111/bju.15870. Online ahead of print.

ABSTRACT

OBJECTIVES: To investigate the timing of the clinical presentation of various types of bacille Calmette-Guérin (BCG) infections in a Finnish population of patients with bladder cancer treated with BCG instillation therapy.

MATERIALS AND METHODS: We identified patients with a history of post-instillation BCG infection from 1996-2016 using the Finnish Cancer Registry and the Finnish National Infectious Diseases Registry. We categorised infections as systemic if the infection was found in the non-urogenital system and genitourinary if the infection affected the urogenital tract. We calculated the time interval between the last BCG instillation and the presentation of the infection. The infection was considered late if the time interval was one year or more.

RESULTS: A total of 100 patients with BCG infection were identified during the study period. Thirty-nine (39%) infections presented as systemic and 61 (61%) were in the genitourinary tract. The majority of the systemic infections presented rapidly after the last instillation, while five (13%) presented after a latency of one year or more. The presentation of genitourinary infections was more heterogeneous, with 12 (20%) presenting as late infections.

CONCLUSION: This study confirms the concept of early and late infection types, especially among systemic infections. However, late infections appeared to be rarer than previously described. Urologists should be aware of the possibility of late BCG infection if patients develop symptoms even several years after the BCG regimen.

Correlation between trunk rotation and lateral flexion range of motion, peak cough flow, and chest expansion in stroke patients

Physiother Res Int. 2022 Aug 12:e1970. doi: 10.1002/pri.1970. Online ahead of print.

ABSTRACT

INTRODUCTION: Stroke patients have problems with voluntary movement and trunk control. Moreover, the respiratory function in stroke patients is affected by neurological impairment, which increases the incidence of respiratory complications.

OBJECTIVES: To determine the correlation between trunk rotation range of motion (TRROM) and trunk lateral flexion range of motion (TLFROM), peak cough flow (PCF), and chest expansion in stroke patients.

METHODS: This was an observational study involving 21 patients with a clinical diagnosis of stroke from October 2021 to January 2022. TRROM and TLFROM were assessed using smartphone applications (Compass and Clinometer), respectively, PCF was assessed using a peak flow meter, and chest expansion was assessed using a tape measure. Pearson’s correlation was used to analyze the relationships between the variables.

RESULTS: Statistically significant correlations were found between TRROM and TLFROM (r = 0.91, p < 0.01) and between upper chest expansion and PCF (r = 0.59, p < 0.01). There were significant correlations between lower chest expansion and TRROM (r = 0.50, p < 0.05) and between lower chest expansion and TLFROM (r = 0.51, p < 0.05).

CONCLUSION: This study demonstrates the relationship between upper chest expansion and PCF. Upper chest expansion exercises should be considered to improve the PCF in stroke patients. In addition, a very strong positive correlation between TRROM and TLFROM was demonstrated. TRROM and TLFROM exercises should be considered to improve the lower chest expansion in stroke patients.

Age-restricted functional and developmental differences of neonatal platelets

J Thromb Haemost. 2022 Aug 12. doi: 10.1111/jth.15847. Online ahead of print.

ABSTRACT

BACKGROUND: Developmental ontogeny of neonatal thrombopoiesis retains characteristics that are distinct from adult although molecular mechanisms remain unestablished METHODS: We applied multiparameter quantitative platelet responses with integrated ribosome profiling/transcriptomic studies to better define gene/pathway perturbations regulating the neonatal-to-adult transition. A bioinformatics pipeline was developed to identify stable, neonatal-restricted platelet biomarkers for clinical application RESULTS: Cord blood (CB) platelets retained the capacity for linear agonist-receptor coupling linked to phosphatidylserine exposure (PS) and α-granule release, although a restricted block in cross-agonist activation pathways was evident. Functional immaturity of synergistic signaling pathways was due to younger ontogenetic age and singular underdevelopment of the protein secretory gene network, with reciprocal expansion of developmental pathways (E2F, G2M checkpoint, c-Myc) important for megakaryocytopoiesis. Genetic perturbations regulating vesicle transport and fusion (TOM1L1, VAMP3, SNAP23, and DNM1L) and PS exposure and procoagulant activity (CLCN3) were the most significant, providing a molecular explanation for globally-attenuated responses. Integrated transcriptomic and ribosomal footprints identified highly-abundant (ribosome-protected) DEFA3 (encoding human defensin neutrophil peptide 3) and HBG1 as stable biomarkers of neonatal thrombopoiesis. Studies comparing CB- or adult-derived megakaryocytopoiesis confirmed inducible and abundant DEFA3 antigenic expression in CB megakaryocytes, ~3.5-fold greater than in leukocytes (the most abundant source in humans). An initial feasibility cohort of at-risk pregnancies manifest by maternal/fetal hemorrhage (chimerism) were applied for detection and validation of platelet HBG1 and DEFA3 as neonatal thrombopoiesis markers, most consistent for HBG1 which displayed gestational age-dependent expression.

CONCLUSIONS: These studies establish an ontogenetically-divergent stage of neonatal thrombopoiesis, and provide initial feasibility studies to track disordered fetal-to-adult megakaryocytopoiesis in vivo.

Evaluation of Applicability of Novel Markers of Metabolic Syndrome in Adult Men

Am J Mens Health. 2022 Jul-Aug;16(4):15579883221108895. doi: 10.1177/15579883221108895.

ABSTRACT

There is a continuous worldwide increase in incidences of metabolic syndrome (MetS) reaching about a quarter of the world’s population. Thus, studies that allow for a robust diagnosis of MetS are of paramount importance from an economic and medical point of view. This study was carried out in a group of men diagnosed with MetS using consensus definition criteria that included the definitions of the International Diabetes Foundation and Diabetes Federation and the American Heart Association/National Heart, Lung, and Blood Institute. The control group consisted of men for whom the parameters that define the MetS were in the norm. This study analyzed statistical differences between MetS and healthy men and the correlations between the set of 14 potential markers of MetS, that is, between body mass index, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein, triglycerides, cortisol, adiponectin, monocyte chemotactic protein-1 (MCP-1), C-reactive protein (CRP), adipsin, leptin, resistin, and plasminogen activator inhibitor-1 (PAI)-1. This report revealed a significant difference between MetS and healthy men in most of the parameters studied. Furthermore, a strong positive correlation between cortisol levels and body mass index was demonstrated. Furthermore, MCP-1 levels in men with MetS were significantly higher than their levels in healthy men. Finally, a strong positive correlation was also observed between adiponectin and adipsin in Mets men. Thus, this study reveals the potential usefulness of adiponectin, MCP-1, adipsin, leptin, resistin, and PAI-1 as markers of MetS in adult men.

What Prospective Applicants Look for on Otolaryngology Residency Websites

Ann Otol Rhinol Laryngol. 2022 Aug 12:34894221118769. doi: 10.1177/00034894221118769. Online ahead of print.

ABSTRACT

OBJECTIVE: To determine what prospective residency applicants look for on otolaryngology residency program websites.

STUDY DESIGN: Survey.

SETTING: The survey was distributed in a virtual format through Google Forms. A link to the survey was given at the University at Buffalo Otolaryngology Chautauqua, sent to Otolaryngology program directors with requests to forward to PGY1 residents and Otolaryngology interest groups, sent to medical school Otolaryngology interest group leaders, posted on Twitter through several accounts, and on otomatch.com.

METHODS: A 45 item survey was given to fourth year medical students applying to otolaryngology, re-applicants applying to otolaryngology, and first year otolaryngology residents who had recently matched. Data collected included participant’s age, sex, race and ethnicity, current status in school/residency program, and their type of medical degree (MD or DO). Participants were then asked to mark the components listed that they wished to see. Components were separated into 5 categories: Application/Selection Criteria, Employment Aspects, Program Features, Social/Community, and Faculty/Contact Information. Data was analyzed using Mann-Whitney and Kruskal Wallis tests when appropriate. P value <.05 was considered statistically significant.

RESULTS: One hundred one surveys were collected. Sixty-four (63.4%) participants were fourth-year medical students, 32 (31.7%) were first-year residents, and 5 (5.0%) were re-applicants. Thirteen of the items on the survey were sought by 80% or more of respondents. Ninety-nine (98.0%) of the participants wanted to see a current resident list with photos and 97 (96.0%) wanted to see the intern year schedule online. Eighty-five percent agreed that salary and benefits information would be valuable on residency websites. Women expressed significantly more interest in salary (P = .034), benefits (P = .026), and parking information (P = .048).

CONCLUSION: Our study provides insight on key items to include on residency program websites. Websites that contain information that applicants want to use can be helpful for application decisions in the future.

The interaction between depression diagnosis and BMI is related to altered activation pattern in the right inferior frontal gyrus and anterior cingulate cortex during food anticipation

Brain Behav. 2022 Aug 12:e2695. doi: 10.1002/brb3.2695. Online ahead of print.

ABSTRACT

BACKGROUND: Depression and overweight/obesity often cooccur but the underlying neural mechanisms for this bidirectional link are not well understood.

METHODS: In this functional magnetic resonance imaging study, we scanned 54 individuals diagnosed with depressive disorders (DD) and 48 healthy controls (HC) to examine how diagnostic status moderates the relationship between body mass index (BMI) and brain activation during anticipation and pleasantness rating of food versus nonfood stimuli.

RESULTS: We found a significant BMI-by-diagnosis interaction effect on activation in the right inferior frontal gyrus (RIFG) and anterior cingulate cortex (ACC) during food versus nonfood anticipation (p < .0125). Brain activation in these regions was greater in HC with higher BMI than in HC with lower BMI. Individuals with DD showed an opposite pattern of activation. Structural equation modeling revealed that the relationship between BMI, activation in the RIFG and ACC, and participants’ desire to eat food items shown in the experiment depended on the diagnostic status.

CONCLUSIONS: Considering that food anticipation is an important component of appetitive behavior and that the RIFG and ACC are involved in emotion regulation, response inhibition and conflict monitoring necessary to control this behavior, we propose that future clinical trials targeting weight loss in DD should investigate whether adequate mental preparation positively affects subsequent food consumption behaviors in these individuals.

Using feasibility dose-volume histograms to reduce intercampus plan quality variability for head-and-neck cancer

J Appl Clin Med Phys. 2022 Aug 12:e13749. doi: 10.1002/acm2.13749. Online ahead of print.

ABSTRACT

The purpose of this work is to objectively assess variability of intercampus plan quality for head-and-neck (HN) cancer and to test utility of a priori feasibility dose-volume histograms (FDVHs) as planning dose goals. In this study, 109 plans treated from 2017 to 2019 were selected, with 52 from the main campus and 57 from various regional centers. For each patient, the planning computed tomography images and contours were imported into a commercial program to generate FDVHs with a feasibility value (f-value) ranging from 0.0 to 0.5. For 10 selected organs-at-risk (OARs), we used the Dice similarity coefficient (DSC) to quantify the overlaps between FDVH and clinically achieved DVH of each OAR and determined the f-value associated with the maximum DSC (labeled as f-max). Subsequently, 10 HN plans from the regional centers were replanned with planning dose goals guided by FDVHs. The clinical and feasibility-guided auto-planning (FgAP) plans were evaluated using our institutional criteria. Among plans from the main campus and regional centers, the median f-max values were statistically significantly different (p < 0.05) for all OARs except for the left parotid (p = 0.622), oral cavity (p = 0.057), and mandible (p = 0.237). For the 10 FgAP plans, the median values of f-max were 0.21, compared to 0.37 from the clinical plans. With comparable dose coverage to the tumor volumes, the significant differences (p < 0.05) in the median f-max and corresponding dose reduction (shown in parenthesis) for the spinal cord, larynx, supraglottis, trachea, and esophagus were 0.27 (8.5 Gy), 0.3 (7.6 Gy), 0.19 (5.9 Gy), 0.19 (8.9 Gy), and 0.12 (4.0 Gy), respectively. In conclusion, the FDVH prediction is an objective quality assurance tool to evaluate the intercampus plan variability. This tool can also provide guideline in planning dose goals to further improve plan quality.

Pre-trained models, data augmentation, and ensemble learning for biomedical information extraction and document classification

Database (Oxford). 2022 Aug 13;2022:baac066. doi: 10.1093/database/baac066.

ABSTRACT

Large volumes of publications are being produced in biomedical sciences nowadays with ever-increasing speed. To deal with the large amount of unstructured text data, effective natural language processing (NLP) methods need to be developed for various tasks such as document classification and information extraction. BioCreative Challenge was established to evaluate the effectiveness of information extraction methods in biomedical domain and facilitate their development as a community-wide effort. In this paper, we summarize our work and what we have learned from the latest round, BioCreative Challenge VII, where we participated in all five tracks. Overall, we found three key components for achieving high performance across a variety of NLP tasks: (1) pre-trained NLP models; (2) data augmentation strategies and (3) ensemble modelling. These three strategies need to be tailored towards the specific tasks at hands to achieve high-performing baseline models, which are usually good enough for practical applications. When further combined with task-specific methods, additional improvements (usually rather small) can be achieved, which might be critical for winning competitions.

Can maternal hormones play a significant role in delivery mode?

J Obstet Gynaecol. 2022 Aug 12:1-8. doi: 10.1080/01443615.2022.2109139. Online ahead of print.

ABSTRACT

The aim of this study was primarily to evaluate the levels of progesterone, oestradiol and relaxin during different delivery modes and secondarily to assess specific traits and changes in maternal pelvic dimensions during pregnancy and childbirth, in correlation with foetal size and maternal hormonal profile. Nulliparous women (n = 448) were evaluated at three different stages, during first trimester, at the time of admission for childbirth and finally just before childbirth. Each examination included clinical internal pelvimetry, blood sample collection for defining the hormones levels in peripheral maternal circulation and ultrasonographic measurements of specific variables of the pubic symphysis and the foetus. We included 304 nulliparous women divided in three groups. According to our results, there was statistically significant difference at the mean progesterone, oestradiol and relaxin range during different modes of childbirth (p-value < .01). We also found significant correlation between the newborn’s weight and the changes in pubic symphysis dimensions. However, no significant association was noted between maternal hormones studied and the changes in pelvic dimensions.IMPACT STATEMENTWhat is already known on this subject? Mode of childbirth can be affected by various aspects, like maternal pelvic anatomy, foetal size and hormonal status at the time of labour. Hormonal fluctuations along with mechanical forces caused by the foetus are believed to lead to morphological alterations to promote natural vaginal childbirth.What do the results of this study add? Our results clearly showed that successful vaginal delivery is characterised by the prevalence of a hyperoestrogenic environment with higher values of intrapartum oestradiol range and significant increase in maternal serum relaxin levels. We also proved that progesterone levels do not decrease during vaginal childbirth, and we concluded that foetal size seems to be the most crucial factor causing alterations in maternal pelvis during parturition.What are the implications of these findings for clinical practice and further research? Our findings could form part of a set of key factors included in future algorithms or computerised biomechanical models for predicting potential childbirth mode. Larger multicenter studies should confirm our results and evaluate their clinical significance in the decision making to ensure safe childbirth and optimal maternal and perinatal outcomes.
