Introduction Breast cancer progression involves physiological mechanisms such as metastasis. Delays in diagnosis and treatment increase the risk of mortality and are associated with barriers to healthcare access. In Chile, breast cancer is highly prevalent, and early diagnosis has improved, although disparities in the disease evolution persist. This study characterized diagnostic and staging tests, waiting times, and sociodemographic profiles to identify delays and inequities in care. Methods Survey study. Using a non-probabilistic sample, a questionnaire was applied in an encrypted platform with prior informed consent. The instrument collected data on requested tests, associated times, staging, and sociodemographic characteristics. These variables were analyzed using descriptive statistics, tests of association, confidence intervals, and comparison tests using bootstrapping. Results A sample of 263 persons was obtained. The most requested tests were biopsy (99.62%) and blood tests (80.23%). The median number of tests requested was six (Q1:4, Q3:8), with a mean of 5.87 (standard deviation: 2.24). No significant differences were observed in the percentage of persons from whom the total number of examinations were requested according to the studied variables. The day-hour-result intervals ranged from 1 to 365 days. The median day-hour-result of the biopsy was 15 days (Q1:10, Q3:30). People between 40 and 49 years old, non-residents of the capital city, belonging to income quintile I, with high school education, from the public health system, with late-stage diagnosis had higher median day-hour-result in biopsy. There was no significant difference in the number of requested tests according to staging (I and II, or III and IV). Conclusions Biopsy in Chile is the test of choice for diagnostic confirmation in breast cancer. Other tests are requested regardless of the diagnosis stage, contrary to the recommendations of clinical guidelines. Cancer prognosis is crucial, especially in countries with greater inequalities.

IntroductionThe relationship between carotid artery stenosis (CAS) and ipsilateral silent brain ischemia (SBI) remains unclear, with uncertain therapeutic implications. The present study, part of the TAXINOMISIS project (nr. 755,320), aimed to investigate SBIs in patients with asymptomatic CAS, correlating them with clinical, carotid ultrasonographic data, and CFD analyses.MethodsThe TAXINOMISIS clinical trial study (nr. NCT03495830) involved six vascular surgery centers across Europe, enrolling patients with asymptomatic and symptomatic CAS ranging from 50 to 99%. Patients underwent carotid ultrasound and magnetic resonance imaging (MRI), including brain diffusion-weighted, T2-weighted/FLAIR, and T1-weighted sequences. Brain MRI scans were analyzed for the presence of SBI according to established definitions. Ultrasound assessments included Doppler and CFD analysis. Only asymptomatic patients were included in this substudy.ResultsAmong 195 asymptomatic patients, the mean stenosis (NASCET) was 64.1%. Of these, a total of 33 patients (16.9%) had at least one SBI detected on a brain MRI scan. Specifically, 19 out of 33 patients (57.6%) had cortical infarcts, 4 out of 33 patients (12.1%) had ipsilateral lacunar infarcts, 6 out of 33 patients had (18.2%) subcortical infarcts, 1 out of 33 patients (3.0%) had both cortical and lacunar infarcts, and 3 out of 33 patients (9.1%) both cortical and subcortical infarcts. Patients with SBIs exhibited significantly higher risk factors, including a higher body mass index (28.52 ± 9.38 vs. 26.39 ± 3.35, p = 0.02), diastolic blood pressure (80.87 ± 15.73 mmHg vs. 80.06 ± 8.49 mmHg, p = 0.02), creatinine levels (93.66 ± 34.61 μmol/L vs. 84.69 ± 23.67 μmol/L, p = 0.02), and blood triglycerides (1.8 ± 1.06 mmol/L vs. 1.48 ± 0.78 mmol/L, p = 0.03). They also had a higher prevalence of cardiovascular interventions (29.6% vs. 13.8%, p = 0.04), greater usage of third/fourth-line antihypertensive treatment (50%vs16%, p = 0.03), and anticoagulant medications (60% vs. 16%, p = 0.01). Additionally, the number of contralateral cerebral infarcts was higher in patients with SBIs (35.5% vs. 13.4%, p

The presence of children and adolescents in migratory flows is growing in Latin America and the Caribbean. Little is known about migration's effects on these groups' health. This article aims to investigate the evidence available on the access and use of healthcare services by migrant children and adolescents in Latin America and the Caribbean. We seek to explore the role of social determinants of health at different levels in the health conditions of these groups. Also, to identify potential recommendations for healthcare systems and public policy to address them. For this purpose, a narrative review of 52 publications was carried out based on a search of scientific literature in the Web of Science and Google Scholar databases. Five relevant topics were identified: use of emergency care associated with lack of healthcare access, preventive services, and other social determinants of health; exposure to preventable infectious diseases; mental health; sexual and reproductive health; and vaccinations and dental health. We conclude that the evidence shows the need to address the inequities and disadvantages faced by migrant children from a perspective of social determinants of health and policies that consider health as a human right regardless of the migratory status of children and adolescents, as well as that of their parents or primary caregivers.

Abstract Background Chile has become a destination country for immigrants from Latin America, including youth. Guaranteeing access and use of sexual and reproductive health services for young migrants is crucial because of their overlapping experiences of transitioning to a new country and to adulthood. However, the existing evidence shows barriers to accessing sexual and reproductive healthcare among young migrant populations. In this context, the main objective of this article is to identify the barriers and facilitators that young migrants experience to access sexual and reproductive healthcare in the Tarapacá region of Chile. Methods A qualitative study was conducted in the Tarapacá region of Chile. Semi-structured interviews with 25 young migrants from Venezuela, Colombia, and Ecuador, as well as 10 health workers, were carried out. The interviews were transcribed and thematically analysed. The study was approved by the Ethics Committee of the Universidad del Desarrollo (#2019-22). Results Young migrants face barriers linked to structural shortcomings within the healthcare system, which may be similar to those faced by the local population. Barriers are also derived from reductionist sexual and reproductive health approaches, which prioritise the prevention of pregnancy, sexually transmitted infections, and HIV, with a predominantly heteronormative focus. The prevailing narratives from the health system are those of risk and lack of control and self-care among young people, and they are exacerbated in the case of migrants. Young migrants, especially from the Caribbean, are stereotyped as over-sexualised and liberal in comparison to the local population and believed to be engaging in riskier sexual behaviours that should be kept under check. This may translate into experiences of discrimination and mistreatment when receiving care. Facilitators include good-quality information and community-level interventions. Conclusions This study shows a limited approach to the sexual and reproductive health of young migrants in Chile, severely hampering their reproductive and sexual rights. Policies and initiatives must work towards removing structural barriers, changing narratives, and empowering young migrants regarding their sexual and reproductive health.

During the first hours after stroke onset, neurological deficits can be highly unstable: some patients rapidly improve, while others deteriorate. This early neurological instability has a major impact on long-term outcome. Here, we aimed to determine the genetic architecture of early neurological instability measured by the difference between the National Institutes of Health Stroke Scale (NIHSS) within 6 h of stroke onset and NIHSS at 24 h. A total of 5876 individuals from seven countries (Spain, Finland, Poland, USA, Costa Rica, Mexico and Korea) were studied using a multi-ancestry meta-analyses. We found that 8.7% of NIHSS at 24 h of variance was explained by common genetic variations, and also that early neurological instability has a different genetic architecture from that of stroke risk. Eight loci (1p21.1, 1q42.2, 2p25.1, 2q31.2, 2q33.3, 5q33.2, 7p21.2 and 13q31.1) were genome-wide significant and explained 1.8% of the variability suggesting that additional variants influence early change in neurological deficits. We used functional genomics and bioinformatic annotation to identify the genes driving the association from each locus. Expression quantitative trait loci mapping and summary data-based Mendelian randomization indicate that ADAM23 (log Bayes factor = 5.41) was driving the association for 2q33.3. Gene-based analyses suggested that GRIA1 (log Bayes factor = 5.19), which is predominantly expressed in the brain, is the gene driving the association for the 5q33.2 locus. These analyses also nominated GNPAT (log Bayes factor = 7.64) ABCB5 (log Bayes factor = 5.97) for the 1p21.1 and 7p21.1 loci. Human brain single-nuclei RNA-sequencing indicates that the gene expression of ADAM23 and GRIA1 is enriched in neurons. ADAM23, a presynaptic protein and GRIA1, a protein subunit of the AMPA receptor, are part of a synaptic protein complex that modulates neuronal excitability. These data provide the first genetic evidence in humans that excitotoxicity may contribute to early neurological instability after acute ischaemic stroke.

Given the profound social implications of climate change, this subject is increasingly important for a broad range of sociology classes. Sociology instructors who address the subject of climate change face a dilemma. Presenting too grim of a portrait risks fostering psychological distress and withdrawal from action to address climate change, whereas downplaying the magnitude of the crisis can provide false assurance that the situation is well in hand and that urgent action is unnecessary. I argue that educators must be sensitive in their presentation of the issue but forthright, even as the scientific evidence indicates that the social impacts of climate change are grim. This does not necessarily foster withdrawal and inaction. Social movement theory suggests that political participation is not primarily a rational pursuit based on calculated outcomes. Educators can inspire climate action by providing students with opportunities and support to do so.

Abstract Background Galcanezumab has shown efficacy and effectiveness in the treatment of episodic and chronic migraine (CM), however, the population represented in randomized clinical trials (RCTs) differs from the population observed in real-world setting. To describe the long-term effectiveness and tolerability of galcanezumab in clinical practice in patients excluded from RCTs. Methods Multicenter prospective cohort study of consecutive patients with chronic and high-frequency episodic migraine (HFEM) with prior failure to three or more migraine preventive drugs, treated with galcanezumab and followed up for 12 months. Results We enrolled 1055 patients, aged 50 (IQR: 42–58), 82.9% female, 76.4% chronic migraine, 69% with at least one exclusion criteria for RCTs, including age > 65 (n = 121), concomitant use of onabotulinumtoxinA (n = 185), daily headache at baseline (n = 347), chronic painful syndromes (n = 206), fibromyalgia (n = 101) or treatment resistance (n = 957). The median number of prior preventive treatments was 4 (IQR: 3–5). The retention rate was 90.8%, 76.8% and 71.4% at 3, 6 and 12 months. The main reasons for treatment discontinuation were lack of effectiveness (21.1%) and inadequate tolerability (6.6%). The 30%, 50% and 75% responder rates were 62.6%, 49.8% and 24.2% between weeks 8–12; 60.9%, 48.8% and 24.6% between weeks 20–24; and 59.7%, 48.3% and 24.6% between weeks 44–48. Daily headache at baseline (OR: 0.619; 95%CI: 0.469–0.817) and patient’s age (OR: 1.016; 95%CI: 1.005–1.026) were associated with 50% response at weeks 20–24. The variables that were associated with a higher reduction of headache days between weeks 20–24 were patient’s age (0.068; 95% CI: 0.018–0.119) and headache days per month at baseline (0.451; 95% CI: 0.319–0.583), while psychiatric comorbidity (-1.587; 95% CI: -2.626—0.538) and daily headache at baseline (-2.718; 95% CI: -4.58—0.869) were associated with fewer reduction in the number of headache days between weeks 20–24. Conclusion This study provides class III evidence of effectiveness and tolerability of galcanezumab in patients with HFEM and CM with comorbidities that would result in exclusion of the pivotal RCTs. Nonetheless, the clinical results over a 12-month period were similar to the efficacy observed in randomized controlled trials. Few patients discontinued the drug due to inadequate tolerability.

On August 31, 2023, the Chilean government ended the health alert for COVID-19. This milestone invites us to reflect on lessons learned in emergency preparedness and response regarding migrant populations in the country. In this context, three perspectives are presented. The first focuses on avoiding pointing to individual responsibility for non-compliance with prevention measures, as this approach ignores structural and historical inequities. Emergency recommendations should be constructed considering a collective approach and diverse sociocultural and political contexts. The second perspective calls for considering and addressing migration as a social determinant of health. During the pandemic, changes in the governance of migration around the world made migration processes more precarious, with risks to the physical and mental health of migrants, which needs better planning and evidence-based decision-making in future pandemics. The third perspective focuses on promoting intercultural health, as effective communication of contagion risks and preventive measures were hampered among migrant populations with diverse worldviews and interpretations of health and disease processes. Responding to the needs of historically marginalized communities requires establishing ways of life that respect diversity in narratives and everyday practices. Governments and health systems must incorporate migration into their emergency preparedness and response strategies, creating the conditions for optimal compliance.

Abstract Background A sustained period of social, economic, and political unrest took place during October of 2019 in Chile. As an institutional solution, the “Agreement for Social Peace and the New Constitution” was signed. In this document, most political parties committed to reestablishing peace and public order in Chile, agreeing on the initiation of a constitutional process. To promote participation of civil society actors, the “Popular Initiative for Norms” was enabled. This was a platform where civilians could submit proposals for constitutional norms to be discussed by the Constitutional Convention. We aimed to analyze proposals related to migrants and migrant health. Methods We conducted a qualitative thematic analysis of the proposals. Sixteen of them were related to migrants, and we analyzed their association to health. We also evaluated their link to the Health Goals 2030 set out by the Chilean Ministry of Health and the Global Action Plan 2019–2023 for Promoting the Health of Refugees and Migrants by the World Health Organization. Results Four main thematic categories were identified: 1) Humans rights of migrants, refugees, and asylum seekers; 2) Nationality and regularization of migrants and refugees; 3) Political participation and cultural integration of migrants and refugees; and 4) Specific regulations on slavery and human trafficking. These resonated with broader frameworks established in the Health Goals 2030 (Chile) and the Global Action Plan 2019–2023 for Promoting the Health of Refugees and Migrants by the World Health Organization. Conclusions The ‘Popular Initiative for Norms’ was a non-binding participatory mechanism. Although the proposals sent through were not guaranteed to be included in the constitutional draft—and despite the final draft being rejected last September 2022—the platform allowed to gain insights into civilian opinions. Our findings showed that there is an incipient yet weak recognition of the rights and situation of migrants in Chile. There was no direct mention of health nor an explicit contemplation of social determinants of health. Despite there being an urgent need to define strategies for migrants’ health in Chile, this study demonstrated that civil awareness and interest are still insufficient.

Abstract Background There is an increasing drive to replace fish oil (FO) in finfish aquaculture diets with vegetable oils (VO), driven by the short supply of FO derived from wild fish stocks. However, little is known of the consequences for fish health after such substitution. The effect of dietary VO on hepatic gene expression, lipid composition and growth was determined in Atlantic salmon (Salmo salar), using a combination of cDNA microarray, lipid, and biochemical analysis. FO was replaced with VO, added to diets as rapeseed (RO), soybean (SO) or linseed (LO) oils. Results Dietary VO had no major effect on growth of the fish, but increased the whole fish protein contents and tended to decrease whole fish lipid content, thus increasing the protein:lipid ratio. Expression levels of genes of the highly unsaturated fatty acid (HUFA) and cholesterol biosynthetic pathways were increased in all vegetable oil diets as was SREBP2, a master transcriptional regulator of these pathways. Other genes whose expression was increased by feeding VO included those of NADPH generation, lipid transport, peroxisomal fatty acid oxidation, a marker of intracellular lipid accumulation, and protein and RNA processing. Consistent with these results, HUFA biosynthesis, hepatic β-oxidation activity and enzymic NADPH production were changed by VO, and there was a trend for increased hepatic lipid in LO and SO diets. Tissue cholesterol levels in VO fed fish were the same as animals fed FO, whereas fatty acid composition of the tissues largely reflected those of the diets and was marked by enrichment of 18 carbon fatty acids and reductions in 20 and 22 carbon HUFA. Conclusion This combined gene expression, compositional and metabolic study demonstrates that major lipid metabolic effects occur after replacing FO with VO in salmon diets. These effects are most likely mediated by SREBP2, which responds to reductions in dietary cholesterol. These changes are sufficient to maintain whole body cholesterol levels but not HUFA levels.

IntroductionEven using well-established technology assessment processes, the basis of the decisions on drug price and reimbursement are sometimes perceived as poorly informed and sometimes may be seen as disconnected from value. The literature remains inconclusive about how Health Technology Assessment Bodies (HTAb) should report the determinants of their decisions. This study evaluates the relationship between oncology and hematology drug list prices and structured value parameters at the time of reimbursement decision in Spain.MethodsThe study includes all new onco-hematological products (22), with a first indication authorized between January 2017 and December 2019 in Spain and pricing decisions published up until October 2022. For each product, 56 contextual and non-contextual indicators reflecting the structured multiple criteria decision analysis (MCDA) – Evidence-based Decision-Making (EVIDEM) framework were measured. The relationship between prices and the MCDA-EVIDEM framework was explored using univariate statistical analyses.ResultsHigher prices were observed when the standard of care included for combinations, if there were references to long-lasting responses, for fixed-duration treatment compared to treatment until progression and treatment with lower frequencies of administration; lower prices were observed for oral administration compared to other routes of administration. Statistically significant associations were observed between prices and the median duration of treatment, the impact on patient autonomy, the ease of use of the drug, and the recommendations of experts.DiscussionThe study suggests that indicators related to the type of standard of care, references to long-lasting responders, the convenience of the use of the drug, and the impact of treatment on patient autonomy, as well as contextual indicators such as the existence of previous clinical consensus, are factors in setting oncology drug prices in Spain. The implementation of MCDA-EVIDEM methodologies may be useful to capture the influence on pricing decisions of additional factors not included in legislation or consolidated assessment frameworks such as the European Network for Health Technology Assessment (EunetHTA) core model. It may be opportune to consider this in the upcoming revision of the Spanish regulation for health technology assessments and pricing and reimbursement procedures.

Abstract Background Globally, it has been reported that different social determinants of health -structural, sociodemographic, economic, living conditions and cultural factors- may affect opportunities to adhere to prevention measures against SARS-CoV-2. The objective of this study was to explore the perceptions around barriers and facilitators for adherence to COVID-19 prevention measures among the adult population residing in three large cities in Chile from a social determinants of health perspective. Methods Qualitative paradigm, multiple case-study design. Online semi-structured interviews were conducted with men and women aged 18 and over from different socioeconomic groups residing in three large cities. For participant recruitment and selection, purposive contacts were made based on community and social media networks, followed by snowball sampling. Saturation was reached at 61 participants, after which a thematic analysis was carried out with the support of AtlasTi software. The Ethics Committee of the Universidad del Desarrollo in Chile approved this study. Results The main perceived barriers to adherence to COVID-19 preventive measures are linked to structural social determinants of health such as income, occupation, gender, access to basic supplies, and housing. Perceived facilitators are the fear of contagion and the incorporation of measures into daily habits. The social communication of preventive measures by health authorities is perceived as punitive, affecting adherence once the fear of contagion decreased in the country. It is also perceived that the recommended preventive measures are disconnected from communities’ cultural practices and people´s identity, as well as affected by gender inequities and socioeconomic conditions that stakeholders in the country do not sufficiently address. Conclusion Study findings suggest that adherence to preventive measures, such as social distancing, mask use, and hand washing, could be promoted through their incorporation into the daily life habits of people and communities. These measures should consider the structural social determinants that generate multiple barriers to adherence, like poverty, occupational risks, and overcrowding. Socio-cultural dimensions of health and everyday risks need further understanding among the different communities in the country, allowing for differences in viewpoints and practices based on gender, age, place, and social identity.

BackgroundGlobally, it has been reported that different social determinants of health affect health outcomes in lung cancer (LC). Research on the therapeutic trajectories of patients (TTP) is a novel field for identifying barriers and facilitators in health. The objective of this study was to reveal perceived differences in TTP with LC in Chile according to selected social determinants of health (SDH) and the experiences of patients, health professionals, and civil society leaders.MethodsThis is a qualitative paradigm, one case-study design. Online semi-structured interviews were conducted with patients with LC, health professionals, and civil society leaders. The strategies for the recruitment process included social networks, civil society organizations, health professionals, and the snowball technique. A thematic analysis was carried out.ResultsSelected SDH impact LC's TTP in Chile, particularly concerning health system access, health services, information, and patient navigation experiences. The analysis of the experiences of the participants allowed us to identify barriers related to the selected SDH in three stages of the TTP: initiation, examinations, and diagnosis and treatment. Individuals with limited education, those residing outside the capital, women, and those in the public health system encountered more barriers throughout their TTP.DiscussionStudy findings suggest that being a woman with low education, from the public health system, and not from the capital might represent one of the most powerful intersections for experiencing barriers to effective healthcare in LC in Chile. It is necessary to monitor the TTP from an SDH perspective to guarantee the rights of access, opportunity, quality, and financial protection.

The existing evidence on burns in the underage population has focused mainly on children under ten years, leaving behind the age group defined as "adolescents" by the World Health Organization. However, adolescents present their own characteristics that differentiate them from their younger counterparts. These differences are relevant from a primary prevention perspective, focusing on preventing illness or injury. In this context, this article reflects on why adolescents need special attention in the primary prevention of burns in Latin America and the Caribbean. First, burn scenarios in adolescents are often linked to participation in risky activities due to pressure, social desirability, or low perception of the associated risks. Second, it is essential to emphasize that adolescents may experience social vulnerability, which entails a higher risk of suffering an intentional or unintentional burn. Third, the risk of burns in adolescents may be related to mental health and self-harm scenarios. These aspects need to be investigated through both quantitative and qualitative studies to design and implement primary prevention strategies relevant to this population group in the region.

Introduction: The relationship between carotid artery stenosis (CAS) and ipsilateral silent brain ischemia (SBI) remains unclear, with uncertain therapeutic implications. The present study, part of the TAXINOMISIS project (nr. 755,320), aimed to investigate SBIs in patients with asymptomatic CAS, correlating them with clinical, carotid ultrasonographic data, and CFD analyses. Methods: The TAXINOMISIS clinical trial study (nr. NCT03495830) involved six vascular surgery centers across Europe, enrolling patients with asymptomatic and symptomatic CAS ranging from 50 to 99%. Patients underwent carotid ultrasound and magnetic resonance imaging (MRI), including brain diffusionweighted, T2-weighted/FLAIR, and T1-weighted sequences. Brain MRI scans were analyzed for the presence of SBI according to established definitions. Ultrasound assessments included Doppler and CFD analysis. Only asymptomatic patients were included in this substudy. Results: Among 195 asymptomatic patients, the mean stenosis (NASCET) was 64.1%. Of these, a total of 33 patients (16.9%) had at least one SBI detected on a brain MRI scan. Specifically, 19 out of 33 patients (57.6%) had cortical infarcts, 4 out of 33 patients (12.1%) had ipsilateral lacunar infarcts, 6 out of 33 patients had (18.2%) subcortical infarcts, 1 out of 33 patients (3.0%) had both cortical and lacunar infarcts, and 3 out of 33 patients (9.1%) both cortical and subcortical infarcts. Patients with SBIs exhibited significantly higher risk factors, including a higher body mass index (28.52  ±  9.38 vs. 26.39  ±  3.35, p  =  0.02), diastolic blood pressure (80.87  ±  15.73  mmHg vs. 80.06  ±  8.49  mmHg, p  =  0.02), creatinine levels (93.66  ±  34.61  μmol/L vs. 84.69  ±  23.67  μmol/L, p  =  0.02), and blood triglycerides (1.8  ±  1.06  mmol/L vs. 1.48  ±  0.78  mmol/L, p  =  0.03). They also had a higher prevalence of cardiovascular interventions (29.6% vs. 13.8%, p  =  0.04), greater usage of third/fourth-line antihypertensive treatment (50%vs16%, p  =  0.03), and anticoagulant medications (60% vs. 16%, p  =  0.01). Additionally, the number of contralateral cerebral infarcts was higher in patients with SBIs (35.5% vs. 13.4%, p  <  0.01). Moreover, carotid ultrasound revealed higher Saint Mary’s ratios (15.33  ±  12.45 vs. 12.96  ±  7.99, p  =  0.02), and CFD analysis demonstrated larger areas of low wall shear stress (WSS) (0.0004  ±  0.0004  m2 vs. 0.0002  ±  0.0002  m2, p  <  0.01). Conclusion: The TAXINOMISIS clinical trial provides valuable insights into the prevalence and risk factors associated with SBIs in patients with moderate asymptomatic carotid stenosis. The findings suggest that specific hemodynamic and arterial wall characteristics may contribute to the development of silent brain infarcts. [ABSTRACT FROM AUTHOR]

The COVID-19 outbreak led to major disruptions in food systems across the globe. In the United States’ Chicago region, the outbreak created immediate concerns around increased hunger, food insecurity, supply chain disruptions, and loss of local liveli­hoods. This was especially evident in communities of color, which faced disproportionate impacts from the pandemic. In March 2020, the Chicago Food Policy Action Council (CFPAC) coordinated a Rapid Response Effort that convened people in working groups related to emergency food assis­tance, local food producers, small businesses, and food system workers to address urgent needs that arose due to the pandemic. Each working group met regularly through virtual calls. This effort has persisted throughout the pandemic in various forms. For this study, we interviewed CFPAC staff members and participants in these calls to create narratives that document respondents’ perceptions of the Rapid Response Effort’s evolution, benefits, challenges, and potential for long-term impacts. Thematic analysis conducted across these narra­tives revealed the importance of network connec­tions to overcoming food system disruptions caused by the COVID-19 pandemic. Our analysis also underscored challenges associated with racism in efforts to strengthen local and regional food sys­tems. These findings indicate a need for research and practice that intentionally attend to power dis­parities related to race within collaborative net­works in order to structure local and regional food systems to achieve greater racial equity and resili­ence to future shocks.

Abstract Damage resulting from the incidence of ultraviolet (UV) radiation on the skin is common nowadays, with UVB (290-320 nm) and UVA (320-400 nm) radiation responsible for photoaging, sunburn and carcinogenesis. For this reason, sunscreens represent products of growing interest to prevent such damage. However, there are few organic filters marketed worldwide with photostability and effectiveness at wavelengths greater than 340 nm (long UVA), which justifies the exploration for new compounds. In this work, we determined the photostability and sun protection factor (SPF) of three 2-(2’-hydroxyphenyl)benzoxazole derivative dyes in order to develop new organic UV filters. UV-vis spectrophotometry has high level of reproducibility when compared with in vivo human clinical methods. Solubility determinations were performed in different solvents. The compounds absorbed UVA and UVB radiation, with maximum absorption wavelengths ranging from 336 to 374 nm. Photostability was evaluated using a solar simulator (3 J.m2.s-1 UVA radiation) for a maximum of 3 h. The 2-(amino-2’-hydroxyphenyl) benzoxazoles showed higher photostability than the acetylated derivative under the evaluated conditions. The three benzoxazoles presented SPF values of around 40 and preliminary results indicate that they show suitable properties to act as good chemical filters in photoprotective formulations.

Advanced therapy medicinal products (ATMPs) are innovative therapies that mainly target orphan diseases and high unmet medical needs. The uncertainty about the product's benefit-risk balance at the time of approval, the limitations of nonclinical development, and the complex quality aspects of those highly individualized advanced therapies are playing a key role in the clinical development, approval, and post-marketing setting for these therapies. This article reviews the current landscape of clinical development of advanced therapies, its challenges, and some of the efforts several stakeholders are conducting to move forward within this field. Progressive iteration of the science, methodologically sound clinical developments, establishing new standards for ATMPs development with the aim to ensure consistency in clinical development, and the reproducibility of knowledge is required, not only to increase the evidence generation for approval but to set principles to achieve translational success in this field.
