Comparative analysis of the incidence of enteroparasitosis andthe COVID-19 pandemic profile in the city of Bananeiras - PB / Análise comparativa da incidência de enteroparasitoses e doperfil pandêmico da COVID-19 na cidade de Bananeiras - PB

Enteroparasitosis are diseases caused by parasitic agents present in the environment and in the gastrointestinal tract of living beings. In addition, they are still considered neglected diseases, but of great importance for public health, especially when they are related to secondary infections and currently their co-infection profile with COVID-19. The interaction of protozoa and/or helminths with the SARS-CoV-2 virus is timely and its signs and symptoms are confused with other pathogen relationships. In this way, this study aims to correlate the incidence of enteroparasitosis and COVID-19, in the pandemic period from 2020 to April 2022. This is a documentary and exploratory study of secondary data from laboratory tests of patients who were treated and diagnosed with COVID-19 and enteroparasitosis at Hospital Doutor Cloves Bezerra Cavalcante, Municipal Hospital of Bananeiras, Paraíba, Brazil. In the analysis of the database, a significant increase of approximately 48.85% in the incidence of COVID-19 cases from 2020 to 2021 stands out, remaining high until 2022. In contrast, cases of enteroparasites peaked at 48.74% in 2021, followed by an average reduction of 23.12%, with a deviation of 1.49%, in relation to the years 2020 and 2022. It was concluded that COVID-19 is predominantly associated with an increase in secondary infections, highlighting the crucial need to promote health education, improve basic sanitation and guarantee access to health services as essential components in combating the increase in parasitic infections, especially those related to viral pathologies.

As enteroparasitoses são enfermidades originadas por agentes parasitários presentes no meio ambiente e no trato gastrointestinal dos seres vivos. Ademais, ainda são consideradas doenças negligenciadas, porém de grande importância para a saúde pública, em especial, quando estão relacionadas com infecções secundárias e atualmente seu perfil de coinfecção com a COVID-19. A interação de protozoários e/ou helmintos com o vírus SARS-CoV-2 é oportuna e seus sinais e sintomas são confundidos com outras relações de patógenos. Desta maneira, este estudo visa correlacionar a incidência de enteroparasitoses e COVID-19, no período pandêmico de 2020 a abril de 2022. Trata--se de uma pesquisa documental e exploratória, de dados secundários dos exames laboratoriais de pacientes que foram atendidos e diagnosticados com COVID-19 e enteroparasitoses no Hospital Doutor Cloves Bezerra Cavalcante, Hospital Municipal de Bananeiras, Paraíba, Brasil. Na análise da base de dados, destaca-se um aumento significativo de aproximadamente 48,85% na incidência de casos de COVID-19 de 2020 a 2021, mantendo-se elevado até 2022. Em contraste, os casos de enteroparasitas atingiram um pico de 48,74% em 2021, seguido por uma redução média de 23,12%, com um desvio de 1,49%, em relação aos anos de 2020 e 2022. Conclui-se que a COVID-19 está predominantemente associada ao aumento de infecções secundárias, destacando a necessidade crucial de promover a educação em saúde, melhorar o saneamento básico e garantir o acesso aos serviços de saúde como componentes essenciais no combate ao aumento de infecções parasitárias, especialmente aquelas relacionadas a patologias virais.

Exploring dynamic public trust in mega infrastructure projects during online public opinion crises of extreme climate emergencies: Users' behaviors, trust dimensions, and effectiveness of strategies.

The vulnerability of mega infrastructure projects (MIPs) has generated online public opinion crises, leading to public trust damage. However, few studies focused on the online dynamic trust of MIPs in such crises from the perspective of multiple users. Based on situational crisis communication theory, this study aims to explore the dynamic public trust in MIPs during online public opinion crises of extreme climate emergencies. The extreme heavy rainstorm event in Zhengzhou City, China, was selected as the case. Content analysis, the curve fitting method, and sentiment analysis were conducted to process the collected data from multiple users. The results indicated that the opinions of trust damage were set by "media practitioners" and led by "elites," whereas the opinions of trust repair were directed by "elites," led by "media practitioners," and defended by "individuals." Besides, trust dimensions would change over time; integrity-based and competence-based trust diffused alternatively. "Diminish," "deny," and "rebuild" strategies were proved to be the most effective strategies in integrity-based, competence-based, and competence and integrity-based trust repair, respectively. The findings can contribute to the authorities monitoring online public opinions in extreme climate emergencies and repairing trustworthy images.

Nipah virus and implications for the nursing workforce and public health: A rapid review.

BACKGROUND: The Nipah virus has raised significant concerns in global health security. During the COVID-19 pandemic, the nursing workforce continues to face numerous challenges, including inadequate preparedness for pandemics, a shortage of nursing personnel, physical, and mental exhaustion. OBJECTIVE: This rapid review aimed to synthesize existing literature on the Nipah virus and its implications for the nursing workforce. DESIGN: A rapid review was conducted to synthesize the available literature on the Nipah virus, facilitating the provision of timely and pertinent information to policymakers and decision influencers. A systematic search strategy was implemented between January 22 and February 9, 2024, from PubMed, CINAHL (EBSCO), Scopus, and Google Scholar without year limitation. Out of 149 studies, six studies were evaluated using the Joanna Briggs Institute Critical Appraisal Checklists, and one study was excluded based on this evaluation, resulting in five studies being included. Then these were reviewed using narrative synthesis. The study adhered to the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. RESULTS: The selected research indicated that the virus was transmitted throughout the community and during hospital admissions, resulting in unexpected mortality. The healthcare staff, especially nurses, had a limited understanding of the infection. Although there is a lack of confidence in policy and decision-makers, many public health initiatives have been implemented such as providing education on infection prevention and control methods to healthcare personnel, including nurses and support staff. CONCLUSION: There is a need to integrate continuing professional development programs in both primary health care and specialized medical care to strengthen the preparedness of healthcare personnel for future pandemics. Support systems not only for healthcare staff members, especially nurses, but also for allied personnel working with them to create conducive working environments.

Memorializing Women on the Move: A register of migrant women landmarks in Europe.

This dataset was developed by COST Action 19112 Women on the Move (WEMov), which engages in unveiling women migrants' presence and participation in the construction of Europe. The dataset was built as a register of toponyms and monuments in the political and public landscape in Europe - such as street names, school names and parks, as well as statues and memorials - that celebrate women migrants. With the dataset we want to discover how women migrants are remembered and what kind of landmarks present these individuals who have had an episode of migration for a variety of reasons. Moreover, our aim is to make these landmarks and the stories of women migrants visible by presenting the results of the dataset in an interactive map on our website. At the moment, the dataset includes 1000 landmarks. The collection of data was based on voluntary work of scholars and students from over 40 different European countries. We have aimed for broad geographical coverage; however, some areas are better represented than others due the nature of data collection. The collection of data is an ongoing process and therefore the dataset in Nakala repository, to which this data note refers, presents the situation in July 2023. Updated versions of the dataset will be made available in Nakala and we will download new landmarks to our interactive map on a regular basis. The selected landmarks and migrant trajectories feature cross-community or cross-cultural migration. They show both typical and exceptional forms of mobility and present women of different age, profession, social status and migration status. This intersectionality of the project and the dataset highlights not only the richness of these landmarks and their value for scholarship but also the wide spectrum of migrant women and their contribution to society.

The dataset shows landmarks in memory of migrant women. These landmarks are the result of political decisions at one point in history to honour these women. The landmarks are tangible and denominated, available in the public space, such as buildings, streets, parks, monuments or gravestones. This collection of data shows how all these landmarks keep the memory of these migrant women alive in daily life. In the dataset we have 1000 landmarks from all over Europe. You can view them on our website.

Observational study of the effects of maximal oxygen uptake on cognitive function and performance during prolonged military exercise.

INTRODUCTION: Military operations place high demands on many cognitive functions, and stressful events characterise the military work environment. The study aimed to examine the relationship between cardiorespiratory fitness, stress response, cognitive function and military performance during prolonged military exercise. METHODS: 66 army cadets were included in the study. The subjects participated in a 4.5-day military winter training in northern Sweden. Maximal oxygen uptake (VO2max) was estimated from a cycle test. Cognitive tests (design fluency, DF test) and measurements of heart rate variability (HRV) were conducted before and after the exercise. Assessment of military performance as an individual soldier (P-ind) and performance as a team leader (P-lead) was carried out during the final day of the exercise. Pearson's coefficient of correlation (r) and Spearman's rho were used to evaluate correlations, and linear regressions were used to examine the relationships between VO2max, HRV, DF test scores and military performance. Simple mediation analyses were performed with DF test scores and military performance (P-ind, P-lead) as dependent variables, VO2max as a predictor and HRV as a mediator. RESULTS: Post-exercise HRV was related to military performance (P-ind: r=0.40, p<0.01; P-lead: r=0.32, p<0.05). Absolute VO2max was positively correlated with P-ind (r=0.28, p<0.05), and the effect of VO2max on military performance was mediated by HRV. Post-test DF scores were negatively correlated with post-exercise HRV (total correct designs: r=-0.26, p<0.05; total incorrect designs: r=-0.27, p<0.05). CONCLUSIONS: Results suggest that high absolute VO2max predicts military performance by reducing the stress response to prolonged military exercise. Aerobic capacity may provide a meaningful effect on the ability to preserve military performance. Future studies need to identify thresholds for this capacity. PRE-REGISTRATION: The protocol was retrospectively registered at OSF (https://osf.io/), registration DOI 10.17605/OSF.IO/ND6XM.

Enhancing the efficacy of healthcare information websites: a case for the development of a best practice framework.

Online healthcare information has the potential to improve health outcomes via the widespread, cost-effective translation of research evidence into practice by healthcare professionals and use by consumers. However, comparatively little is known about how healthcare professionals and consumers engage with healthcare websites, or whether the knowledge that is made available through digital platforms is translated into better health outcomes. To realise the potential of such resources, we argue that an evidence-based framework-grounded in a nuanced understanding of how audiences engage with and use information provided by healthcare websites-is needed. The goal of this paper is to outline a case for the development of a best-practice framework that can guide the development of websites that provide healthcare information to clinicians and consumers. In addition to supporting the design of more effective online resources, a common framework for understanding how better health outcomes can be achieved via digital knowledge translation has the potential to significantly improve patient outcomes in the face of a complex, rapidly changing and resource-constrained healthcare landscape.

Caesarean sections, indications and outcomes: a cross-sectional study using the Robson classification in a tertiary hospital in Sierra Leone.

OBJECTIVE: WHO recommends the use of the Robson's 'Ten Groups Classification' for monitoring and assessing caesarean section (CS) rates. The aim of this study was to investigate the rates, indications and outcomes of CS using Robson classification in a tertiary hospital in Sierra Leone. DESIGN: Cross-sectional study. SETTING: Princess Christian Maternity Hospital (PCMH), Freetown, Sierra Leone. PARTICIPANTS: All women who gave birth in PCMH from 1 October 2020 to 31 January 2021. PRIMARY AND SECONDARY OUTCOME MEASURES: Primary outcome: CS rate by Robson group. SECONDARY OUTCOMES: indications for CS and the newborn outcomes for each Robson group. RESULTS: 1998 women gave birth during the study period and 992 CS were performed, with a CS rate of 49.6%. Perinatal mortality was 7.8% and maternal mortality accounted for 0.5%. Two-thirds of the women entered labour spontaneously and were considered at low risk (groups 1 and 3). CS rates in these groups were very high (43% group 1 and 33% group 3) with adverse outcomes (perinatal mortality, respectively, 4.1% and 6%). Dystocia was the leading indication for CS accounting for about two-thirds of the CS in groups 1 and 3. Almost all women with a previous CS underwent CS again (95%). The group of women who give birth before term (group 10) represents 5% of the population with high CS rate (50%) mainly because of emergency conditions. CONCLUSION: Our data reveals a notably high CS rate, particularly among low-risk groups according to the Robson classification. Interpretation must consider PCMH as a referral hospital within an extremely low-resourced healthcare system, centralising all the complicated deliveries from a vast catchment area. Further research is required to assess the impact of referred obstetrical complications on the CS rate and the feasibility of implementing measures to improve the management of women with dystocia and previous CS.

Impact of NGOs' undercover videos on citizens' emotions and pro-social behaviors.

Undercover videos have become a popular tool among NGOs to influence public opinion and generate engagement for the NGO's cause. These videos are seen as a powerful and cost-effective way of bringing about social change, as they provide first-hand evidence and generate a strong emotional response among those who see them. In this paper, we empirically assess the impact of undercover videos on support for the cause. We in addition analyze whether the increased engagement among viewers is driven by the negative emotional reactions produced by the video. To do so, we design an online experiment that enables us to estimate both the total and emotion-mediated treatment effects on engagement by randomly exposing participants to an undercover video (of animal abuse) and randomly introducing a cooling-off period. Using a representative sample of the French population (N=3,310), we find that the video successfully increases actions in favor of animals (i.e., donations to NGOs and petitions), but we fail to prove that this effect is due to the presence of primary emotions induced by the video. Last, we investigate whether activists correctly anticipate their undercover videos' (emotional) impact via a prediction study involving activists (exploratory analysis).

Constructs from the Consolidated Framework for Implementation Research associated with church enrollment and intervention adoption in a national implementation study of a faith-based organizational change intervention.

BACKGROUND: Organizational adoption is a key but understudied step in translating evidence-based interventions into practice. The purpose of this study was to report recruitment strategies and factors associated with church enrollment and intervention adoption in a national implementation study of the Faith, Activity, and Nutrition (FAN) program. METHODS: We worked with partners using multiple strategies to disseminate intervention availability. Interested churches completed an online form. To enroll, the church coordinator (FAN coordinator) and pastor completed baseline surveys and then received intervention online training access. We compared enrolled vs. non-enrolled churches on how they heard about the study and church characteristics. We compared intervention-adopting vs. non-adopting churches on Consolidated Framework for Implementation Research (CFIR) constructs using Fisher's exact tests, χ2, or independent sample t-tests and reported differences where p < 0.10, d≥|0.35|, or the difference in percentage points was ≥ 10. RESULTS: We received 226 interest forms; 107 churches enrolled, and 85 churches adopted the intervention. Faith-based sources were the most, and paid media the least, effective in reaching churches, which were largely from the southeast with a Methodist or Baptist tradition (no differences by enrollment status). Enrolled churches were less likely to have 500 + worshipers and more likely to have attended a study information session than non-enrolled churches. Church (CFIR inner setting) and FAN coordinator characteristics, but not intervention characteristics, were related to intervention adoption. CONCLUSION: Partnerships, relationships, and "face time" are important for enrolling churches in evidence-based interventions. Church and church coordinator characteristics are related to intervention adoption. Further work on adoption conceptualization and operationalization is needed.

Conflict and fragmented public health emergency management system in Tigray region of Northern Ethiopia: A double burden to accommodate resilient and advanced public health emergency management. A commentary review for policy-makers and a call to action.

An estimated 2.5 million people have been internally and externally displaced in the Tigray region of northern Ethiopia in conflict and post-conflict settings. This induced a loss of access to basic and essential healthcare services. The situation was overwhelming, causing service inaccessibility, inadequate health facilities, unstable security to access the services, shortage of supplies and drugs, and medical equipment's in the region. The regional public health emergency management is one service delivery set up for the critically ill. It is characterized by weak emergency management capacities, poor coordination and integration. In addition, the system falls in to two independent sectors in the Tigray Health Bureau (THB), Tigray Health Research Institute (THRI). This leads to a fragmented system, an unclear leadership and governance role and a poor service delivery setup and tracking mechanism. The situation leads to resource duplication and poor business practice. Indeed, this type of service delivery setup secures personal and professional interest more than community interest. The situation exacerbated the occurrence of recurrent outbreaks in the region, with, for instance, zoonotic diseases (anthrax and rabies), acute watery diarrhoea, measles, malaria, yellow fever, and coronavirus disease 2019 (COVID-19) approaching to their level of epidemic. Moreover, they will spike as an epidemic in the future. All these circumstances made it evident that the system need reform to adhere with legal global, national, and regional frameworks, guidelines and proclamations. The system should have one service delivery set up at regional level. It must fall into regional public health institutes (PHIs) to adhere its service packages to the current advancements. Furthermore, integrated effort need from program implementers, relevant stakeholders and policy-makers should be committed and work together in the review and reform process.

Mind the gap in kidney care: translating what we know into what we do / Atenção às lacunas no cuidado renal: traduzindo o que sabemos em ações

Abstract Historically, it takes an average of 17 years for new treatments to move from clinical evidence to daily practice. Given the highly effective treatments now available to prevent or delay kidney disease onset and progression, this is far too long. Now is the time to narrow the gap between what we know and what we do. Clear guidelines exist for the prevention and management of common risk factors for kidney disease, such as hypertension and diabetes, but only a fraction of people with these conditions are diagnosed worldwide, and even fewer are treated to target. Similarly, the vast majority of people living with kidney disease are unaware of their condition, because it is often silent in the early stages. Even among patients who have been diagnosed, many do not receive appropriate treatment for kidney disease. Considering the serious consequences of kidney disease progression, kidney failure, or death, it is imperative that treatments are initiated early and appropriately. Opportunities to diagnose and treat kidney disease early must be maximized beginning at the primary care level. Many systematic barriers exist, ranging from the patient to the clinician to the health systems to societal factors. To preserve and improve kidney health for everyone everywhere, each of these barriers must be acknowledged so that sustainable solutions are developed and implemented without further delay.

Resumo Historicamente, são necessários, em média, 17 anos para que novos tratamentos passem da evidência clínica para a prática diária. Considerando os tratamentos altamente eficazes disponíveis atualmente para prevenir ou retardar o início e a progressão da doença renal, esse período é demasiadamente longo. Agora é o momento de reduzir a lacuna entre o que sabemos e aquilo que fazemos. Existem diretrizes claras para a prevenção e o manejo dos fatores de risco comuns para doenças renais, como hipertensão e diabetes, mas apenas uma fração das pessoas com essas condições é diagnosticada mundialmente, e um número ainda menor recebe tratamento adequado. Da mesma forma, a grande maioria das pessoas que sofrem de doença renal não têm conhecimento de sua condição, pois ela costuma ser silenciosa nos estágios iniciais. Mesmo entre pacientes que foram diagnosticados, muitos não recebem tratamento adequado para a doença renal. Levando em consideração as graves consequências da progressão da doença renal, insuficiência renal ou óbito, é imperativo que os tratamentos sejam iniciados precocemente e de maneira adequada. As oportunidades para diagnosticar e tratar precocemente a doença renal devem ser maximizadas, começando no nível da atenção primária. Existem muitas barreiras sistemáticas, que vão desde o paciente até o médico, passando pelos sistemas de saúde e por fatores sociais. Para preservar e melhorar a saúde renal para todos em qualquer lugar, cada uma dessas barreiras deve ser reconhecida para que soluções sustentáveis sejam desenvolvidas e implementadas sem mais demora.

Public health preparedness, syndromic surveillance, and response during the largest religious gathering at the Catholic pilgrimage center of Velankanni in South India: 2016.

Background: The dynamicity and mobility of the population in a mass gathering setting pose a challenge to traditional disease surveillance methods and strain the local health services. Velankanni is one of the most sacred Christian pilgrimage places located in Nagapattinam, Tamil Nadu, India. We participated in the Velankanni festival to describe the public health preparedness, surveillance, and response activities carried out during the festival. Methods: This was a cross-sectional study. We reviewed the national and international guidelines and published literature and discussed with the key stakeholders. We developed a checklist to observe public health preparedness activities. We facilitated the staff and monitored the activities by the implementers. We established the syndromic surveillance in the designated locations of the event and used tracker software to capture the data. Emergency medical teams were formed with trained health personnel to respond to medical emergencies. Results: The team monitored all the public health activities. There are 59 primary care public health facilities and nine ambulatory Mobile Medical Units, with 160 medical officers available at the site. Of the 16,169 persons who attended the medical camps, 9863 (61%) were males and 8408 (52%) were aged 15-44. Acute diarrheal disease was the most frequent of the reported syndromes, followed by injuries, acute febrile illness, and animal bites. Conclusions: There was no outbreak of any disease either identified or reported. Our findings suggest that risk assessments should be used, and establishing an Incident Command Center is vital for executing command and control mechanisms during mass gatherings.

Serotype-specific clinical features and spatial distribution of dengue in northern Kerala, India.

Background: Collection and compilation of spatial, meteorological, entomological, and virological data are critical in mitigating climate-sensitive emerging infections like dengue. This study was a holistic attempt to understand the dengue situation in the Kasaragod district of Kerala, India. Methods: This cross-sectional study was conducted in 13 health institutions from June to July 2021. Adult patients presenting with fever and testing positive for NS1 ELISA were subjected to Dengue RT-PCR and serotyping. The spatial and clinical features of the RT-PCR-positive patients, the district's meteorological data, and the vector indices were studied. Results: The pre-epidemic months were marked by intermittent rainfall, peak ambient temperature and high larval indices. Among the 136 dengue RT-PCR patients studied, 41.2% had DENV2 followed by DENV1 (22.8%), DENV3 (5.9%) and DENV4 (4.4%); with 25% mixed infections. DENV1 showed a higher risk of gastrointestinal manifestations (80.6%, p=0.019) and musculoskeletal symptoms (77.4%, p=0.026) compared with other serotypes. Conclusions: In the context of dengue hyperendemicity, the possibility of an emerging serotype's dominance coupled with the mixing up of strains should warn the health system regarding future outbreaks. Furthermore, the study emphasizes the importance of monitoring larval indices and the window of opportunity to intervene between environmental predictors and dengue outbreaks.

Emerging role of vitamin D deficiency as a risk factor for retinal venous occlusions and need for public health measures for its prevention.

Purpose: To estimate levels of serum vitamin D in patients of retinal vein occlusion (RVO) and compare with age- and sex-matched controls. Methods: A prospective case-control study of 54 patients of RVO and 54 age- and sex-matched attendants of patients presenting to a tertiary care hospital in Delhi was performed. Patients on vitamin D supplementations and RVO due to infective or immunological causes or patients of glaucoma were excluded. Serum vitamin D levels of all the study participants along with relevant blood investigations with history and examination were documented. Vitamin D deficiency was defined as <20 ng/ml. Results: The mean serum vitamin D levels seen in RVO patients and the control group were 14.19 ± 5.23 ng/ml and 19.42 ± 10.27 ng/ml, respectively (P value = 0.001) with an odds ratio of 10.558 (CI = 2.34-47.50), indicating vitamin D deficiency to be strongly correlated with RVO. Maximum patients of RVO (46.3%) were seen during the winter season. The study noted hypertension [odds ratio 20.22 (CI = 5.812-70.347)], dyslipidemia, and anemia [odds ratio 4.107 (CI = 0.62-26.90)] to be the risk factors for RVO as previously proved in the literature. Smoking, diabetes, alcohol intake, and body mass index did not emerge as risk factors for RVO. Conclusion: Vitamin D deficiency is associated with RVO; hence, estimation of serum vitamin D levels should be advised as a part of routine investigations while looking for the cause of RVOs. Public health measures like food fortification with vitamin D micronutrients and public awareness towards increased sunlight exposure in the community are simple, inexpensive measures that can decrease the burden of sight-threatening disease of RVO in the community.

"The Walls Had Been Built": A Qualitative Study of Canadian Adolescent Perspectives on Mental Health During the COVID-19 Pandemic.

Public health measures (PHMs) implemented during the COVID-19 pandemic introduced sudden changes to adolescents' everyday routines and required adolescents to repeatedly adapt their routines at a critical developmental stage. While meant to protect physical health, the PHMs destabilized mental health. Using a youth-engaged approach and interpretive description, this study explored adolescents' perspectives on their mental health in relation to the COVID-19 pandemic-related PHMs in Canada from March 2020 to the time of data collection in March 2022. Four Youth Research Collaborators contributed an adolescent lens to informing study activities, and a total of 33 high-school aged adolescents ages 14 to 19 completed individual interviews. Findings suggest an overarching concept of a "timeline" through which adolescents described their experiences. Most adolescents described their mental health as worsening during the initial lockdown, although some adolescents experienced positive mental health outcomes. Several adolescents felt their mental health had not recovered after the PHMs were fully lifted. This study contributes young Canadians' unique voices to the literature on the pandemic-related PHMs and adolescent mental health. It is essential that the impacts of the pandemic on adolescent mental health continue to be a focus of research and programming to better understand and address its ongoing effects.

Craniometric determinants of the fitted filtration efficiency of disposable masks.

Introduction: Exposure to harmful aerosols is of increasing public health concern due to the SARS-CoV-2 pandemic and wildland fires. These events have prompted risk reduction behaviors, notably the use of disposable respiratory protection. This project investigated whether craniofacial morphology impacts the efficiency of disposable masks (N95, KN95, surgical masks, KF94) most often worn by the public to protect against toxic and infectious aerosols. This project was registered with ClinicaltTrials.gov (NCT05388201; registration May 18, 2022). Methods: One-hundred participants (50 men, 50 women) visited the Environmental Protection Agency's Human Studies Facility in Chapel Hill, NC between 2022-2023. Craniometrics and 3D scans were used to separate participants into four clusters. Boosting and elastic net regression yielded five measurements (bizygomatic breadth, nose length, bizygomatic nasal arc, neck circumference, ear breadth) that were the best predictors of filtration efficiency based on overall model fit. Fitted filtration efficiency was quantified for each mask at baseline and when tightened using an ear-loop clip. Results: The mean unmodified mask performance ranged from 55.3% (15.7%) in the large KF94 to 69.5% (12.3%) in the KN95. Modified performance ranged from 66.3% (9.4%) in the surgical to 80.7% (12.0%) in the KN95. Clusters with larger face width and neck circumference had higher unmodified mask efficiency. Larger nose gap area and nose length decreased modified mask performance. Discussion: We identify face width, nose size, nose shape, neck circumference, and ear breadth as specific features that modulate disposable mask fit in both unmodified and modified conditions. This information can optimize guidance on respiratory protection afforded by disposable ear-loop masks.

Temporal changes in the physical fitness of Chinese adolescents aged 13-18 years: an analysis of eight national successive surveys over three decades.

Objective: The aim of this study was to assess temporal changes in physical fitness of Chinese adolescents aged 13-18 years from 1985 to 2019. Methods: Body size /composition and physical fitness indicators, including body height, weight, body mass index (BMI), speed, power, flexibility, muscular endurance, and cardiorespiratory fitness (CRF), were selected from Chinese boys and girls aged 13-18 years from eight Chinese National Surveillance on Students' Constitution and Health from 1985 to 2019. Temporal changes in means were estimated by sample-weighted linear regression at the test × sex × age level, and national trends were estimated by a post-stratification population weighting procedure. Results: Overall mean body height, weight and BMI increased significantly for Chinese adolescents over 34 years. There was a small improvement for boys in speed (Effect size [ES] = -0.21, 95% confidence interval [CI] = -0.44 ~ 0.02), a small improvement for boys in power (ES = 0.24, 95% CI = -0.20 ~ 0.69), a small improvement for girls in flexibility (ES = 0.45, 95% CI = 0.15 ~ 0.76), a moderate decline for boys (ES = -0.53 95% CI = -0.84 ~ -0.21) and a moderate improvement for girls (ES = 0.61, 95% CI = -0.03 ~ 1.26) in muscular endurance, and large declines in cardiorespiratory fitness (CRF) for boys (ES = 0.93, 95% CI = 0.64 ~ 1.21) and girls (ES = 0.93, 95% CI = 0.58 ~ 1.27) from 1985 to 2019. These trends in each component of fitness were more positive for adolescents aged 13-15 years than that of adolescents aged 16-18 years in both sexes, except for girls in flexibility. Conclusion: The decline in CRF was most pronounced among Chinese children and adolescents from 1985 to 2019, suggesting a future decline in population health that needs attention.

Current political uses of sport revised: beyond public diplomacy and sportswashing.

The successful emergence of the Gulf states as central players in the global sporting ecosystem has revived the intellectual debate on the political and diplomatic use of sport. In the last decade, the amount of research on the topic have radically increase. The old narrative traditions explaining sport diplomacy have recently been joined by a new set of literature about the concept of sportswashing, which questions the place of non-democratic governments in the sporting world. Considering that current approaches are somehow limited to explain the real scope of the situation, this article proposes a new systematization of the political and diplomatic use of sport today, differentiating between practices, actors, and objectives. The aim is to demonstrate how sport as a tool of soft power has transcended the limits of public diplomacy and goes far beyond the simplistic and preconceptual analysis developed by authors who support the concept of sportswashing. The new conceptual framework warns that the politicization of sport is not always positive and shows how some political practices can jeopardies the core values of sport and delegitimize its positive aspect. The results open a new agenda for political science research on a topic that, despite its interest and importance, remains understudied.

Radiography managers' perceptions on skills required in public health institutes in Gauteng.

Background: Management of radiography departments requires skilled and competent managers. This task becomes complex if there is no management development and collaborative performance monitoring. Aim: The study aimed to explore and describe the radiography managers' perceptions regarding management training and skills required. Setting: The research was conducted in public health institutions of Gauteng, South Africa. Methods: Qualitative, exploratory and descriptive approach was adopted, and a purposive sampling method was used to select twenty-three (23) managers from the radiography departments; however, data saturation guided the sample size. Data were collected through online focus group discussions (FGDs). Ethical approval was obtained through Departmental Research Committee (DRC) of Medical Imaging and Radiation Sciences (MIRS) department, Higher Degrees Committee (HDC), Research Ethics Committee and Gauteng Department of Health Research Committees.
