To tackle the plastic problem, the worldwide campaign ‘Plastic Free July’ aims at encouraging people to reduce single-use plastics during the month of July. To get people started with new behavior patterns, so-called ‘windows of opportunity’—periods where people become open for new experiences—are expected to matter. Therefore, the current study evaluated if an arbitrary month that is framed as an opportunity for change can interrupt people in their daily routines and reduce plastic consumption. An online survey (n = 509) with repeated measures (n = 366) was conducted including one experimental and one control group. The experimental group was invited to reduce their single-use plastic consumption during July in line with the ‘Plastic Free July’ campaign. Results revealed that, in this action period, single-use plastic consumption was slightly but significantly lower in the experimental than in the control group, which did not receive any information about ‘Plastic Free July’. The campaign seemed to be more effective for participants with low pro-environmental identity. Path analysis revealed that plastic consumption (prior to the intervention) was significantly predicted by perceived difficulty, habits, and pro-environmental identity. Policy support was predicted by problem awareness, pro-environmental identity and perceived barriers. We conclude with recommendations for plastic-free purchase and policy support.

Flavored Tobacco

Background As of September 2020, more than 300 state and local jurisdictions restrict the sales of flavored tobacco, with some including menthol. Aims o evaluate the impact of local ordinances restricting the sale of flavored tobacco, we surveyed Californians regarding policy support and perceived access to flavored tobacco. Methods In 2019, we conducted an online survey of 3,075 California youth and young adults recruited via social media, about half of whom lived in a policy jurisdiction. Logistic regressions assessed differences on propensity score–weighted outcomes, policy support, and perceived access. Results Most respondents indicated agreement with almost all policy support statements. Although policy respondents were less likely than rest-of-California respondents to report perceived difficulty in buying flavored cigars, flavored vape users in policy jurisdictions were more likely than those in the rest of California to report perceived difficulty in buying flavored e-liquid. Regardless of jurisdiction, certain priority subgroups were significantly more likely to report perceived difficulty in accessing flavored cigars, flavored vaping products, flavored e-liquid, and menthol cigarettes. Discussion With some exceptions, these findings demonstrate that among vape users in policy jurisdictions and priority subgroups, there is a higher likelihood of reporting perceived difficulty to access flavored tobacco products. Conclusions Findings might be an early indication of shifts in social norms about flavored tobacco products in California, which could gain traction as local sales restriction ordinances proliferate throughout the state and a statewide flavored-tobacco sales restriction goes into effect.

While augmented feedback (AF) is widely acknowledged to affect motor learning, the effects of mode of feedback on motor learning acquisition, retention, and perceived competence has rarely been studied. The present investigation analyzes the effects of verbal, haptic, and combined (verbal and haptic) feedback when learning a novel gymnastic parallel bars task. Forty-eight physical education students and four expert gymnastics teachers participated in the study. We divided the students into three AF groups (verbal, haptic, and combined) and a no-feedback control group (CG). One gymnastics teacher led the learning sessions, while the others evaluated student performances following familiarization, acquisition, and retention learning phases. All sessions were video recoded, and the experts gave blind assessments according to an adapted gymnastic point code. We recorded task perceived difficulty (PD) and students' perceived self-competency throughout the sessions. A repeated measures analysis of variance revealed a significant effect of AF mode on acquisition and retention such that combined AF was best for learning stability and retention (19.1% improvement for combined vs. 9.9% for haptic and 6.9% for verbal). Similarly, participants in the combined AF group, relative to the verbal and haptic AF groups, also reported lower perceived difficulty and higher perceived self-competency after the retention phase. PE teachers are encouraged to combine verbal and haptic AF when teaching new motor skills.

Abstract Ageist attitudes and loneliness negatively impact both younger and older adults (e.g., Sun et al., 2019). This study utilized a randomized waitlist-control design to investigate the effects of a six-week intergenerational e-mail pen pal program on loneliness in younger and older adults and ageism in younger adults. Thirty-three younger adults (18-30 years) and 28 older adults (over age 65) completed an online survey assessing ageist attitudes, loneliness, well-being, and other individual differences. One week after completing a baseline survey, 17 email pen pal pairs began the six-week e-mail intervention. Participants repeated the survey one week after the completion of the intervention (which was eight weeks after the baseline for the control participants). Analyses showed that at baseline, younger adults (M=2.41, SD=.76) reported higher levels of loneliness compared to older adults (M=1.65, SD=.77), t(59) = 3.85, p < .001. Repeated measures ANOVAs showed that the intervention did not have a significant effect on ageism or loneliness in either younger or older adults. However, the effect size of the intervention for loneliness among older adults was moderate to large (η2= .07). Descriptive statistics indicated that older adults in both the intervention and control groups experienced an increase of loneliness during the post-test. However, the older adults in the intervention group experienced less of an increase compared to older adults in the control group. This suggests that the intervention may have buffered the increase in loneliness that older adults may experience during the winter months and during the onset of the COVID-19 pandemic.

Background: The Coronavirus Disease 2019 (COVID-19) pandemic has caused numerous unexpected challenges for many families, and these long-lasting demands likely contribute to higher stress for parents. The aim of this study was to describe changes in parent stress longitudinally from before (retrospective) to two timepoints during COVID-19. Stressors that influenced parenting and strategies to manage parenting difficulties at each timepoint during COVID-19 are also described.Methods: Parents (N = 433; 95% female) in the US with >1 child aged 5–18 years completed an online survey in May 2020 (T1; at the peak of stay-at-home mandates) and in September 2020 (T2; children's return to school). Surveys included the 10-item Perceived Stress Scale (PSS) and questions on parenting-specific stress, stressors that influenced parenting, and strategies to manage parenting difficulties during COVID-19. Retrospective report of pre-COVID-19 stress was assessed at T1; current stress was assessed at T1 and T2. Repeated measures analysis of variance examined changes in stress over time.Results: Parent's stress increased from before COVID-19 to T1 (PSS score: 16.3 ± 5.7 to 22.0 ± 6.4, respectively; p < 0.01), and decreased by T2 (19.2 ± 6.0), but remained elevated above pre-COVID-19 values (p < 0.01). Most parents (71.1%) reported an increase parenting-specific stress from before COVID-19 to T1, which continued to increase for 55% of parents at T2. Common stressors that impacted parenting during COVID-19 were changes in children's routines, worry about COVID-19, and online schooling demands. Common strategies parents used to manage parenting difficulties included doing family activities together, keeping in touch with family/friends virtually, and keeping children on daily routines.Conclusions: Parent stress increased substantially during COVID-19 and has not returned to pre-COVID-19 levels, suggesting the need for enhanced mental health resources and supports. Public health interventions should address parenting-specific stressors and effective strategies for managing parenting difficulties to mitigate their deleterious impact.

Covid 19 is considered to be a pandemic virus infection. SARS-Cov-2 causes it. It is a viral infection that is transmitted through aerosol and droplet contamination, cross-infection, etc. Dentists are at a higher risk due to this corona. It has affected daily routines of dentist's life as they are unavailable to run the clinic and attend to patients. Different search engines like PubMed, and Google Scholar was used. The questionnaire consisting of twenty questions was prepared by using online survey google forms and circulated among the participants. SPSS software was used to evaluate the results and data collection. Statistical analysis was done by chi-square test. Later, results were being tabulated. This survey that is taken among dental students, dentists, and random public, it is seen that the majority of them are well aware of this recent pandemic attack. (COVID-19). It is concluded that dentists are affected to a significant extent due to coronavirus as their daily routine is affected severely. This study aims to identify the effect on dentist life on a routine basis due to the pandemic COVID - 19.

OBJECTIVEThe authors hypothesized that new agents such as BioGlue would be as efficacious as kaolin in the induction of hydrocephalus in fetal sheep.METHODSThis study was performed in 34 fetal lambs randomly divided into 2 studies. In the first study, fetuses received kaolin, BioGlue (2.0 mL), or Onyx injected into the cisterna magna, or no injection (control group) between E85 and E90. In the second study, fetuses received 2.0-mL or 2.5-mL injections of BioGlue into the cisterna magna between E85 and E90. Fetuses were monitored using ultrasound to assess lateral ventricle size and progression of hydrocephalus. The fetuses were delivered (E120–E125) and euthanized for histological analysis. Selected brain sections were stained for ionized calcium binding adaptor 1 (Iba1) and glial fibrillary acidic protein (GFAP) to assess the presence and activation of microglia and astroglia, respectively. Statistical comparisons were performed with Student’s t-test for 2 determinations and ANOVA 1-way and 2-way repeated measures for multiple determinations.RESULTSAt 30 days after injection, the lateral ventricles were larger in all 3 groups that had undergone injection than in controls (mean diameter in controls 3.76 ± 0.05 mm, n = 5). However, dilatation was greater in the fetuses injected with 2 mL of BioGlue (11.34 ± 4.76 mm, n = 11) than in those injected with kaolin (6.4 ± 0.98 mm, n = 7) or Onyx (5.7 ± 0.31 mm, n = 6) (ANOVA, *p ≤ 0.0001). Fetuses injected with 2.0 mL or 2.5 mL of BioGlue showed the same ventricle dilatation but it appeared earlier (at 10 days postinjection) in those injected with 2.5 mL. The critical threshold of ventricle dilatation was 0.1 for all the groups, and only the BioGlue 2.0 mL and BioGlue 2.5 mL groups exceeded this critical value (at 30 days and 18 days after injection, respectively) (ANOVA, *p ≤ 0.0001). Moderate to severe hydrocephalus with corpus callosum disruption was observed in all experimental groups. All experimental groups showed ventriculomegaly with significant microgliosis and astrogliosis in the subventricular zone around the lateral ventricles. Only kaolin resulted in significant microgliosis in the fourth ventricle area (ANOVA, *p ≤ 0.005).CONCLUSIONSThe results of these studies demonstrate that BioGlue is more effective than Onyx or kaolin for inducing hydrocephalus in the fetal lamb and results in a volume-related response by obstructive space-occupancy without local neuroinflammatory reaction. This novel use of BioGlue generates a model with potential for new insights into hydrocephalus pathology and the development of therapeutics in obstructive hydrocephalus. In addition, this model allows for the study of acute and chronic obstructive hydrocephalus by using different BioGlue volumes for intracisternal injection.

Background. Abdominal and lumbo-pelvic stability alterations may be the origin of lower limb injuries, such as adductor pathology in soccer players. Imbalance can be caused by both intrinsic and extrinsic factors. Methods: In this randomized controlled trial over 8 weeks, 25 female footballers were randomly allocated to an experimental group (isometric abdominal training and gluteus medius-specific training) or a control group (isometric abdominal training). Evaluations were performed at baseline, at the end of the intervention and after a 4-week follow-up period. The exercise protocol in common for both groups included three exercises: Plank, Lateral plank and Bird dog. Specific exercises for the gluteus medius were: Pelvic drop and Stabilization of the gluteus medius in knee valgus. Outcome measures were lumbar-pelvic stability and adductor strength. Results: After the intervention, there was an increase in lumbo-pelvic stability in both groups, being greater in the control group than in the experimental group (mean differences [MD]: 4.84 vs. MD: 9.58; p < 0.01) with differences in the analysis of repeated measures (p < 0.001), but not in group interaction (p = 0.26). Changes were found in adductor strength in the experimental group (MD: −2.48; p < 0.001 in the left adductor; MD: −1.48; p < 0.01 in right adductor) and control group (MD: −1.68; p < 0.001 in the left adductor; MD: −2.05; p < 0.001 in the right adductor) after the intervention, with differences in the analysis of repeated measures in left (p < 0.001) and right (p < 0.001) adductor strength. Conclusions: An abdominal and gluteal training protocol shows no advantage over a protocol of abdominal training alone for lumbo-pelvic stability and adductor strength, while improvements in both variables are maintained at four weeks follow-up.

Abstract Background The purpose of this study was to assess the cytotoxicity of various concentrations of ozonated water (OW) on human primary dental pulp cells. Methods Human primary dental pulp cells were isolated from exfoliated primary canine teeth of an 11-year-old patient with good systemic and oral health. Afterwards, cells were divided into 6 experimental groups; four groups of OW in concentrations of 2 mg/L, 4 mg/L, 8 mg/L, and 16 mg/L, untreated control group, and cell culture without cells. Cytotoxicity was evaluated after exposure for 5-min exposure using Mosmann’s Tetrazolium Toxicity (MTT) assay at 0 h and 48 h time points. Data were analyzed using a repeated measures analysis of variance and Post-hoc tests were performed using Bonferroni correction for multiple comparisons. Results All experimental groups showed proliferation at 0 h time point. However, all groups also experienced a decrease in overtime at 48 h time point (p < 0.05). At both time points 2 mg/L OW showed the highest cell viability as well as proliferation. At 0 h time point, the increase in cell viability for all experimental groups was found statistically significant when compared to positive control group (p < 0.05). At 48 h time point, although 8 mg/L and 16 mg/L OW showed statistically significant reduction in compare to 0 h time point, 2 mg/L and 4 mg/L OW groups didn’t experience any statistically significant difference (p < 0.05). Conclusion Considering our findings, due to ozonated water's induced a higher proliferation rate of dental pulp cells, indicating their biocompatibility and a possible adjuvant on irrigating agent in regenerative endodontic procedures.

AimsTo determine myopia progression in children who continued to wear the defocus incorporated multiple segments (DIMS) lenses or switched from single vision (SV) to DIMS lenses for a 1-year period following a 2-year myopia control trial.Methods128 children participated in this study. The children who had worn DIMS lenses continued to wear DIMS lenses (DIMS group), and children who had worn SV lenses switched to wear DIMS lenses (Control-to-DIMS group). Cycloplegic spherical equivalent refraction (SER) and axial length (AL) were measured at 6-month interval. Historical controls were age matched to the DIMS group at 24 months and used for comparing the third-year changes.ResultsOver 3 years, SER and AL changes in the DIMS group (n=65) were −0.52±0.69D and 0.31±0.26 mm; these changes were not statistically significant over time (repeated measures analysis of variance, p>0.05).SER (−0.04±0. 38D) and AL (0.08±0.12 mm) changes in the Control-to-DIMS group (n=55) in the third year were less compared with the first (mean difference=0.45 ± 0.30D, 0.21±0.11 mm, p<0.001) and second (0.34±0.30D, 0.12±0.10 mm, p<0.001) years.Changes in SER and AL in both groups over that period were significantly less than in the historical control group (DIMS vs historical control: mean difference=−0.18±0.42D, p=0.012; 0.08±0.15 mm, p=0.001; Control-to-DIMS versus historical control: adjusted mean differences=−0.30±0.42D, p<0.001; 0.12±0.16 mm, p<0.001).ConclusionsMyopia control effect was sustained in the third year in children who had used the DIMS spectacles in the previous 2 years and was also shown in the children switching from SV to DIMS lenses.
