Clinical trials are research studies that look at new ways to prevent, detect, or treat diseases and conditions. Although individuals may benefit from being part of a clinical trial, participants should be aware that the primary purpose of a clinical trial is to gain new scientific knowledge so that others may be better helped in the future.

The aim is to reduce disease morbidity and transmission towards the elimination of the disease as public health problem. Periodic treatment of at-risk populations will cure mild symptoms and prevent infected people from developing severe, late-stage chronic\r\n disease. However, a major limitation to schistosomiasis control has been the limited availability of praziquantel, particularly for the treatment of adults. Data for 2021 show that 29.9% of people requiring treatment were reached globally, with a\r\n proportion of 43.3% of school-aged children requiring preventive chemotherapy for schistosomiasis being treated. A drop of 38% compared to 2019, due to the COVID-19 pandemic which suspended treatment campaigns in many endemic areas.

In summary, phases one and two of the current COVID-19 pandemic represent a dangerous accumulation of risk factors for mental health problems in children and adolescents of enormous proportions: re-organization of family life, massive stress, fear of death of relatives, especially with relation to grandparents and great-grandparents, economic crisis with simultaneous loss of almost all support systems and opportunities for evasion in everyday life, limited access to health services as well as a lack of social stabilization and control from peer groups, teachers at school, and sport activities.
Declaring racism a public health crisis has the potential to shepherd meaningful anti-racism policy forward and bridge long standing divisions between policy-makers, community organizers, healers, and public health practitioners. At their best, the declarations are a first step to address long standing inaction in the face of need. At their worst, the declarations poison or sedate grassroots momentum toward anti-racism structural change by delivering politicians unearned publicity and slowing progress on health equity. Declaring racism as a public health crisis is a tool that must be used with clarity and caution in order to maximize impact. Key to holding public institutions accountable for creating declarations is the direct involvement of Black and Indigenous People of Color (BIPOC) led groups and organizers. Sharing power, centering their voices and working in tandem, these collaborations ensure that declarations push for change from the lens of those most impacted and authentically engage with the demands of communities and their legacies. Superficial diversity and inclusion efforts that bring BIPOC people and organizers into the conversation and then fail to implement their ideas repeat historical patterns of harm, stall momentum for structural change at best, and poison the strategy at worst. In this paper we will examine three declarations in the United States and analyze them utilizing evaluative criteria aligned with health equity and anti-racism practices. Finally, we offer recommendations to inform anti-racist public health work for meaningful systematic change toward decentralization and empowerment of communities in their health futures.
Previous studies have found that countries with higher government effectiveness took longer to implement domestic COVID-19 related policy responses such as school closure (e.g., [36, 39], perhaps due to (mis)perception that a well-functioning state should be able to cope with such a crisis as the current coronavirus pandemic and therefore, has more time or propensity to learn from others and develop well-considered COVID-19 response plans. Therefore, we also control for governance capacity; the data for which is based on measures of state capacity in the Government Effectiveness dimension of the 2019 Worldwide Governance Indicators (the World Bank).
We employ the time-to-event analysis (survival analysis or event history analysis) to examine the role of globalization in the timing of international travel restriction policies. Similar to previous studies [37, 38, 50], we use the marginal risk set model  to estimate the expected duration of time (days) until each policy, with increasing strictness, was imposed by each country. Specifically, we model the hazard for implementing screening, quarantine, ban on high-risk regions, and total border closure separately; thus, allowing the possibility that a country may adopt a more restrictive policy early on, as countries are assumed to be simultaneously at risk for all failures (i.e., implementation of any level of policy strictness). Intuitively, as more stringent policies are less likely to be implemented or adopted early (especially if state capacity is high), we stratified the baseline hazards for the four restrictions to allow for differences in policy adoption rate. Yet, when a country adopts a more restrictive travel restriction policy (e.g., total border closure) before (or never) implementing the less restrictive ones (e.g., ban on high-risk regions), the latter is effectively imposed (at least from an outcome perspective). Thus, we code them as failure on the day the more restrictive policy was implemented.Footnote 9 We also stratify countries by the month of the first confirmed COVID-19 case,Footnote 10 as countries with early transmission of coronavirus have fewer other countries from which they can learn how best to respond to the pandemic . This is important because disproportionally more countries with a higher globalization index contracted the virus early (Fig. S2 in the SI Appendix). Additionally, we stratify time observations into before and after pandemic declaration (11 March 2020)  as it is likely to significantly increase the likelihood of countries adopting a travel restriction policy (particularly for border closures as seen in Fig. 2) as consensus on the potential severity of the pandemic solidified. Out of all 184 countries in our sample, 3 and 39 did not implement ban on high-risk regions and total border closure, respectively, before the end of the sample period, and are thus (right) censored (Fig. 1); i.e., nothing is observed or known about that subject and event after this particular time of observation.
Several clinical trials comparing HAES to conventional obesity treatment have been conducted. Some investigations were conducted before the name "Health at Every Size" came into common usage; these earlier studies typically used the terms "non-diet" or "intuitive eating" and included an explicit focus on size acceptance (as opposed to weight loss or weight maintenance). A Pub Med search for "Health at Every Size" or "intuitive eating" or "non-diet" or "nondiet" revealed 57 publications. Randomized controlled trials (RCTs) were vetted from these publications, and additional RCTs were vetted from their references. Only studies with an explicit focus on size acceptance were included.
Evidence: Long-term follow-up studies document that the majority of individuals regain virtually all of the weight that was lost during treatment, regardless of whether they maintain their diet or exercise program [5, 27]. Consider the Women's Health Initiative, the largest and longest randomized, controlled dietary intervention clinical trial, designed to test the current recommendations. More than 20,000 women maintained a low-fat diet, reportedly reducing their calorie intake by an average of 360 calories per day  and significantly increasing their activity . After almost eight years on this diet, there was almost no change in weight from starting point (a loss of 0.1 kg), and average waist circumference, which is a measure of abdominal fat, had increased (0.3 cm) .
Table 3 presents a summary of the eight case studies examined in this analysis according to the chemicals and chemical groups most pervasive in each exposure event and the numbers and percentages of people (where data was available) who were exposed and subsequently developed illness and TILT. As shown, the number of people exposed across the various events ranged from fewer than a dozen (moldy home case) to several hundred thousand (Gulf War Illness).
To date, the identification of TILT initiators stems from observational reports and studies of major exposure events, as highlighted in this analysis. Noteworthy, however, is a study undertaken for the European Commission [5, 6] that revealed other initiators including wood-preservative chemicals (pentachlorophenol), organic solvents, anesthetic agents, carpets and glue, and formaldehyde.
A growing number of studies have investigated potential neurobiological underpinnings of dissociation, which are not yet fully understood. A recent systematic review of 205 neuroimaging studies suggests that enhanced task-related activity of the inferior frontal gyrus and medial prefrontal cortex may be linked to dissociation . Largely in line with this, another systematic review concluded that functional alterations in frontal regions are most consistently observed in individuals with dissociative symptoms . This may point to an increased recruitment of brain regions implicated in arousal modulation [21, 40]. Further evidence for this idea stems from studies that used script-driven imagery to induce acute dissociative symptoms and study their impact on information processing. Patients with acute dissociation after script-driven imagery showed increased activity in the inferior frontal gyrus during an inhibitory task [25, 26].
