Success in long-term weight management depends partly on psychological and behavioral aspects. Understanding the links between psychological factors and eating behavior tendencies is needed to develop more effective weight management methods. This population-based cross-sectional study examined whether eating self-efficacy (ESE) is associated with cognitive restraint (CR), uncontrolled eating (UE), emotional eating (EE), and binge eating (BE). The hypothesis was that individuals with low ESE have more unfavorable eating behavior tendencies than individuals with high ESE. Participants were classified as low ESE and high ESE by the Weight-Related Self-Efficacy questionnaire (WEL) median cut-off point. Eating behavior tendencies were assessed with Three Factor Eating Questionnaire R-18 and Binge Eating Scale, and additionally, by the number of difficulties in weight management. The difficulties were low CR, high UE, high EE, and moderate or severe BE. Five hundred and thirty-two volunteers with overweight and obesity were included in the study. Participants with low ESE had lower CR (p < 0.03) and higher UE, EE, and BE (p < 0.001) than participants with high ESE. Thirty-nine percent of men with low ESE had at least two difficulties in successful weight control while this percentage was only 8% in men with high ESE. In women, the corresponding figures were 56% and 10%. The risk of low ESE was increased by high UE [OR 5.37 (95% CI 1.99–14.51)], high EE [OR 6.05 (95% CI 2.07–17.66)], or moderate or severe BE [OR 12.31 (95% CI 1.52–99.84)] in men, and by low CR [OR 5.19 (95% CI 2.22–12.18)], high UE [OR 7.20 (95% CI 2.41–19.22)], or high EE [OR 23.66 (95% CI 4.79–116.77)] in women. Low ESE was associated with unfavorable eating behavior tendencies and multiple concomitant difficulties in successful weight loss promotion. These eating behavior tendencies should be considered when counseling patients with overweight and obesity.

Valid and useful dietary assessment methods for adolescents with type 1 diabetes (T1D) are needed. In this study, we compared an image-based method with a written food diary for dietary intake estimation among adolescents with T1D and evaluated the adolescents’ experiences of the methods. Adolescents with T1D aged 13 to 18 years (n = 13) photographed their meals (n = 264) with a mobile phone camera and simultaneously kept a written food diary for four consecutive days. The participants filled out electronic background and feedback questionnaires. The agreement between the methods was evaluated using intraclass correlation coefficients (ICCs) and Bland–Altman plot analyses. The agreement between the methods was moderate to excellent for the energy intake (ICC = 0.91, 95% confidence interval (CI): 0.66 to 0.97, p < 0.001) and good to excellent for total carbohydrate intake (ICC = 0.95, 95% CI: 0.84 to 0.99, p < 0.001). The adolescents considered photographing easier and faster than keeping a food diary. In conclusion, the image-based method appeared comparable to the food diary for dietary intake estimation among adolescents with T1D. The photographing of meals may become a useful dietary assessment tool for adolescents with T1D, but must be further developed and validated.

Background Regardless of competitive athletes’ body image pressures, only few studies have focused on adolescent sport participants’ body image and the findings are inconclusive. Furthermore, the role of competitive goals in sports on adolescents’ body size perception has not been studied. We examined the factors associated with adolescents’ competitive goals in sports and body size perception, and the associations between adolescents’ competitive goals in sports and body size perception. Methods The cross-sectional study consisted of 475 goal-oriented sports club participants and 936 reference youths (aged 14–16 years). The study questionnaire included multiple choice items on health behaviours, motives to exercise, competitive goals in sports and body size perception. The multinomial logistic regression analysis was used to investigate the associations. Results Adolescents with competitive goals in sports perceived their body size as about the right size more frequently than reference youths (68% vs 47%, p  < 0.001 in girls; 74% vs 61%, p  < 0.001 in boys). More than one-fourth of girls with competitive goals in sports perceived themselves as overweight, although only 7% of them were overweight. Adolescents with appearance/weight motives to exercise and poor perceived physical fitness had higher odds of perceived fatness. Additionally, BMI was positively associated with perceived fatness and negatively with perceived thinness. Having competitive goals in sports was not independently associated with perceived fatness or perceived thinness. Conclusions Adolescents’ BMI, appearance/weight motives to exercise, and perceived physical fitness were more strongly associated with body size perception than their competitive goals in sports. However, perceived fatness among girls with competitive goals in sports should be considered in organized sports.

Background Although sports clubs’ potential for health promotion is acknowledged, research on whether they promote healthy eating is limited. We aimed to evaluate Finnish youth sports clubs’ health promotion orientation, as well as associations between sports clubs’ health promotion orientation, coaches’ nutritional discussions and sports club participants’ (SPs’) fruit and/or vegetable consumption. Methods The cross-sectional study included 554 SPs aged 14–16 years, 275 club officials and 311 coaches. Participants replied to questionnaires about sports clubs’ health promotion and their own health behaviours, including dietary habits. Health promotion orientation was estimated using a Health Promoting Sports Club (HPSC) index (range 0–22) and nutritional discussions and fruit and/or vegetable consumption as frequencies. A mixed-effects multivariable logistic regression was used to analyse the associations. Results Most sports clubs (69%) had a high health promotion orientation, but the variation between the clubs was wide (HPSC index range 5–21). SPs’ daily fruit and/or vegetable consumption was associated with female gender [odds ratio (OR) 3.48, 95% confidence interval (CI) 2.23–5.42, P < 0.001], better self-rated health (OR 3.26, 95% CI 1.13–9.41, P = 0.03), higher average school grades (OR 1.67, 95% CI 1.04–2.67, P = 0.03), and SPs’ responses that their coach had often discussed nutrition (OR 2.11, 95% CI 1.41–3.14, P < 0.001). Conclusion Although sports clubs’ orientation towards health promotion was mostly high, it seems not to be enough to promote healthy eating among adolescent participants. Instead, coaches’ nutritional discussions were associated with adolescents’ fruit and/or vegetable consumption.

African desert dust is emitted and long-range transported with multiple effects on climate, air quality, cryosphere, and ecosystems. On 21–23 February 2021, dust from a sand and dust storm in northern Africa was transported to Finland, north of 60°N. The episode was predicted 5 days in advance by the global operational SILAM forecast, and its key features were confirmed and detailed by a retrospective analysis. The scavenging of dust by snowfall and freezing rain in Finland resulted in a rare case of substantial mineral dust contamination of snow surfaces over a large area in the southern part of the country. A citizen science campaign was set up to collect contaminated snow samples prepared according to the scientists’ instructions. The campaign gained wide national interest in television, radio, newspapers and social media, and dust samples were received from 525 locations in Finland, up to 64.3°N. The samples were utilised in investigating the ability of an atmospheric dispersion model to simulate the dust episode. The analysis confirmed that dust came from a wide Sahara and Sahel area from 5000 km away. Our results reveal the features of this rare event and demonstrate how deposition samples can be used to evaluate the skills and limitations of current atmospheric models in simulating transport of African dust towards northern Europe.

Mechanical forces of the tumor microenvironment change dynamically during key events of tumorigenesis such as invasion and metastasis. These changes in compressive forces often affect the breast cancer cell phenotype. However, it is lesser known how these dynamic mechanical forces in the tumor microenvironment affect the phenotypes of tumor infiltrated leukocytes (TIL) and their subsequent anticancer activities. Here we find, in primary patient-derived explant cultures (PDEC) containing resident TILs, that low compression promotes a change in the original identity of breast cancer cells from luminal to a more mesenchymal and undifferentiated state. These altered tumor cells induce an upregulation of immunosuppressive cytokines such as interleukin-10 (IL-10) and Transforming Growth Factor Beta (TGF-β), as well as polarization of macrophages towards pro-tumor M2(Gc)-type and depletion of CD8+ effector memory T-cells. These immunosuppressive events are mediated by tumor cell derived fibroblast growth factor 2 (FGF2) and prostaglandin E2 (PGE2). We also find that FGF2 rich areas in primary tumors show enrichment in M2-like-macrophages and diminished numbers of CD8 + T and B-cells. Our results suggest that low compressive forces in the tumor microenvironment induce local immunosuppression via FGF2 secretion arising from phenotypic plasticity of tumor cells. Mechanical forces modulate tumor cell phenotype, which in turn shapes the tumor microenvironment and contributes to downstream processes such as invasion and metastasis. Here authors show in primary patient-derived breast cancer explant cultures that low compression changes the tumour cells to a less differentiated state, leading to secretion of immunosuppressive cytokines, which impacts the tumor resident immune cells.

Dental healthcare personnel (DHCP) are subjected to microbe-containing aerosols and splatters in their everyday work. Safer work conditions must be developed to ensure the functioning of the healthcare system. By simulating dental procedures, we aimed to compare the virus-containing aerosol generation of four common dental instruments, and high-volume evacuation (HVE) in their mitigation. Moreover, we combined the detection of infectious viruses with RT-qPCR to form a fuller view of virus-containing aerosol spread in dental procedures. The air–water syringe produced the highest number of aerosols. HVE greatly reduced aerosol concentrations during procedures. The air–water syringe spread infectious virus-containing aerosols throughout the room, while other instruments only did so to close proximity. Additionally, infectious viruses were detected on the face shields of DHCP. Virus genomes were detected throughout the room with all instruments, indicating that more resilient viruses might remain infectious and pose a health hazard. HVE reduced the spread of both infectious viruses and viral genomes, however, it did not fully prevent them. We recommend meticulous use of HVE, a well-fitting mask and face shields in dental procedures. We advise particular caution when operating with the air–water syringe. Due to limited repetitions, this study should be considered a proof-of-concept report.

PurposeCervical lesions caused by human papillomavirus (HPV) are related to decreased quality of life (QoL) of women. Also, cervical cancer (CC) screening can cause psychological adverse effects. It has been assumed that by decreasing the HPV-related disease burden, HPV vaccinations would increase the QoL. This study compares the effect of CC screening on QoL of HPV vaccinated women in two different screening protocols.MethodsA total of 753 HPV16/18 vaccinated women were randomized to frequent (22/25/28 years of age) and infrequent (28 years of age) CC screening arms. QoL questionnaires (EQ VAS, RAND 36, amended CECA 10) were sent at the age of 28.ResultsMedian EQ VAS scores were 80 (Q1–Q3 75–90) in both screening arms. Mean RAND 36 scores of frequently and infrequently screened women were 78.13/81.64 in Physical role functioning domain and, respectively, 77.93/80.18 in Pain, 69.10/69.12 in General Health, 54.67/53.61 in Energy, 83.72/85.11 in Social functioning, 69.53/69.68 in Emotional role functioning, and 68.16/69.29 in Emotional well-being domain. Among women with a self-reported history of Pap cytology abnormalities, overall mean scores of amended CECA 10 were 69.52/72.07, and among women with a self-reported history of genital warts, 60.09/66.73, respectively.ConclusionThere was no significant difference in the QoL of HPV vaccinated women between the two CC screening arms. Women were mostly satisfied with the screening experience despite the screening frequency. This information is important for the future screening program planning as we need to reach the best possible balance with screening benefits and harms.Trial registration numberNCT02149030, date of registration 29/5/2014.

This article examines digital communication in the workplace and its association with wellbeing at work. The analysis is based mainly on workshop discussions and is complemented with log data (N = 36). Content analysis was applied to the workshop discussions, while the log data were analyzed by quantifying frequencies. Six themes were found to affect wellbeing at work: the volume of digital communication, expectations of constant connectivity, the quality of the messages, adaptation of new tools, technical problems, and flexibility in communication. In relation to wellbeing at work, digital communication was mostly perceived as demanding. However, some of the factors perceived as demanding could also provide flexibility, which was seen as enhancing wellbeing by increasing autonomy and control. Social factors, such as work habits, practices, and conventions in the workplace, seem to play an important role in the manifestation and management of the digital communication-induced load at work.

Breast cancer is now globally the most frequent cancer and leading cause of women’s death. Two thirds of breast cancers express the luminal estrogen receptor-positive (ERα + ) phenotype that is initially responsive to antihormonal therapies, but drug resistance emerges. A major barrier to the understanding of the ERα-pathway biology and therapeutic discoveries is the restricted repertoire of luminal ERα + breast cancer models. The ERα + phenotype is not stable in cultured cells for reasons not fully understood. We examine 400 patient-derived breast epithelial and breast cancer explant cultures (PDECs) grown in various three-dimensional matrix scaffolds, finding that ERα is primarily regulated by the matrix stiffness. Matrix stiffness upregulates the ERα signaling via stress-mediated p38 activation and H3K27me3-mediated epigenetic regulation. The finding that the matrix stiffness is a central cue to the ERα phenotype reveals a mechanobiological component in breast tissue hormonal signaling and enables the development of novel therapeutic interventions. Subject terms: ER-positive (ER + ), breast cancer, ex vivo model, preclinical model, PDEC, stiffness, p38 SAPK. Reliable luminal estrogen receptor (ERα+) breast cancer models are limited. Here, the authors use patient derived breast epithelial and breast cancer explant cultures grown in several extracellular matrix scaffolds and show that ERα expression is regulated by matrix stiffness via stress-mediated p38 activation and H3K27me3-mediated epigenetic regulation.
