Introduction: Neuromyelitis optica spectrum disorder (NMOSD) is a serious condition affecting people worldwide, including Latin America (LATAM). Healthcare disparities and economic limitations make effective treatment access challenging. It is crucial to consider the best practice therapeutic decision-making, including emerging long-term preventive therapies, to ensure patients in LATAM and elsewhere can effectively manage their disease all over the world.

Combined association of physical activity and depressive symptoms with cardiometabolic risk factors in Chilean adults.

Cardiometabolic risk factors such as obesity, raised blood pressure, high blood glucose and dyslipidemia are emerging health concerns worldwide. Therefore, the aim of this study was to estimate the combined association between physical activity and depressive symptoms with cardiometabolic risk factors in Chilean adults. Data was obtained from the National Health Survey of Chile 2016-2017, with a sample of 5995 adult participants.

Relationship between perceived stress and health literacy on family satisfaction among family members of critically ill patients: A multicenter exploratory study.

Background: Intensive care unit (ICU) admission is often a stressful experience that can negatively influence family satisfaction (FS) with patient care, communication, and decision-making. Health literacy (HL) is associated with the patient's ability to obtain, process, and understand health-related information. Few studies have explored the influence of perceived stress and HL on FS simultaneously.

Design of an innovative nanovehicle to enhance brain permeability of a novel 5-HT6 receptor antagonist.

An innovative nanovehicle based on lipid nanocapsules (LNC) was designed to facilitate the passage of a new 5-HT receptor antagonist, namely PUC-10, through the blood-brain barrier. PUC-10 is a new synthetic -arylsulfonylindole that has demonstrated potent 5-HT receptor antagonist activity, but it exhibits poor solubility in water, which indicates limited absorption. The lipid nanocapsules designed had a nanometric size (53 nm), a monomodal distribution (PI<0.

Prospective Teacher's Voice Questionnaire (PTVQ): Development of a Questionnaire to Assess Training-Related Voice Symptoms Among Prospective Teachers.

Aim: To develop and validate a self-administered population-specific survey, available in Spanish, Portuguese, and English, which investigates the prevalence of voice symptoms and perceptions of risk factors associated with training among prospective teachers.

Methods: The present study had three stages: the first stage included a literature review and content validation by experts that supported the survey development. From this phase, we defined five aspects of the Prospective Teacher's Voice Questionnaire (PTVQ): (1) target population, (2) research objectives, (3) questions to be included, (4) scales for the answers, and (5) relevance, comprehensiveness, clarityclarity, and understandability of the questions.

Bridging the gap: returning genetic results to indigenous communities in Latin America.

In response to inequality in access to genomics research, efforts are underway to include underrepresented minorities, but explicit (and enforcing) guidelines are mostly targeted toward the Global North. In this work, we elaborate on the need to return scientific results to indigenous communities, reporting the actions we have taken in a recent genomic study with Mapuche communities in Chile. Our approach acknowledged the social dynamics perpetuating colonial hierarchies.

Clinical and pulmonary function analysis in long-COVID revealed that long-term pulmonary dysfunction is associated with vascular inflammation pathways and metabolic syndrome.

Introduction: Long-term pulmonary dysfunction (L-TPD) is one of the most critical manifestations of long-COVID. This lung affection has been associated with disease severity during the acute phase and the presence of previous comorbidities, however, the clinical manifestations, the concomitant consequences and the molecular pathways supporting this clinical condition remain unknown. The aim of this study was to identify and characterize L-TPD in patients with long-COVID and elucidate the main pathways and long-term consequences attributed to this condition by analyzing clinical parameters and functional tests supported by machine learning and serum proteome profiling.

Methods: This retrospective study included 86 adult Hispanic men (60 ± 8.2 years, median prostate-specific antigen density (PSA-D) 0.

Factors influencing the implementation of shared decision-making in breast cancer care: protocol for a mixed-methods study.

Introduction: Chile is committed to actively involving patients in their healthcare. However, little is known about how this is translated into clinical encounters. Breast cancer (BC) is the first cause of cancer-related death in Chilean women.

The genetic history of the Southern Andes from present-day Mapuche ancestry.

The southernmost regions of South America harbor some of the earliest evidence of human presence in the Americas. However, connections with the rest of the continent and the contextualization of present-day indigenous ancestries remain poorly resolved. In this study, we analyze the genetic ancestry of one of the largest indigenous groups in South America: the Mapuche.

Love and affectionate touch toward romantic partners all over the world.

Touch is the primary way people communicate intimacy in romantic relationships, and affectionate touch behaviors such as stroking, hugging and kissing are universally observed in partnerships all over the world. Here, we explored the association of love and affectionate touch behaviors in romantic partnerships in two studies comprising 7880 participants. In the first study, we used a cross-cultural survey conducted in 37 countries to test whether love was universally associated with affectionate touch behaviors.

Improvements in Compassion and Fears of Compassion throughout the COVID-19 Pandemic: A Multinational Study.

During large-scale disasters, social support, caring behaviours, and compassion are shown to protect against poor mental health outcomes. This multi-national study aimed to assess the fluctuations in compassion over time during the COVID-19 pandemic. Respondents (Time 1 = 4156, Time 2 = 980, Time 3 = 825) from 23 countries completed online self-report questionnaires measuring the flows of compassion (i.

Need for approval from others and face concerns as predictors of interpersonal conflict outcome in 29 cultural groups.

The extent to which culture moderates the effects of need for approval from others on a person's handling of interpersonal conflict was investigated. Students from 24 nations rated how they handled a recent interpersonal conflict, using measures derived from face-negotiation theory. Samples varied in the extent to which they were perceived as characterised by the cultural logics of dignity, honour, or face.

Modernization, collectivism, and gender equality predict love experiences in 45 countries.

Recent cross-cultural and neuro-hormonal investigations have suggested that love is a near universal phenomenon that has a biological background. Therefore, the remaining important question is not whether love exists worldwide but which cultural, social, or environmental factors influence experiences and expressions of love. In the present study, we explored whether countries' modernization indexes are related to love experiences measured by three subscales (passion, intimacy, commitment) of the Triangular Love Scale.

When material science meets microbial ecology: Bacterial community selection on stainless steels in natural seawater.

The passive film depends on the alloy's composition and the exposure conditions. How the surface composition affects the selection of microbial biofilms though, has not been fully elucidated or incorporated into the analysis of corrosive biofilms. The degradation of stainless steel (SS) exposed to natural seawater was studied to understand how the oxide layer composition of SS could affect the selection and variability of the bacterial community.

Observing many researchers using the same data and hypothesis reveals a hidden universe of uncertainty.

This study explores how researchers' analytical choices affect the reliability of scientific findings. Most discussions of reliability problems in science focus on systematic biases. We broaden the lens to emphasize the idiosyncrasy of conscious and unconscious decisions that researchers make during data analysis.

Network pharmacology reveals multitarget mechanism of action of drugs to be repurposed for COVID-19.

The coronavirus disease 2019 pandemic accelerated drug/vaccine development processes, integrating scientists all over the globe to create therapeutic alternatives against this virus. In this work, we have collected information regarding proteins from SARS-CoV-2 and humans and how these proteins interact. We have also collected information from public databases on protein-drug interactions.

Hedonic perception of odors in children aged 5-8 years is similar across 18 countries: Preliminary data.

Objective: Olfactory preference emerges very early in life, and the sense of smell in children rapidly develops until the second decade of life. It is still unclear whether hedonic perception of odors is shared in children inhabiting different regions of the globe.

Methods: Five-hundred ten healthy children (N = 510; n = 256; n = 254) aged from 5 to 8 years from 18 countries rated the pleasantness of 17 odors.

Compassion Protects Mental Health and Social Safeness During the COVID-19 Pandemic Across 21 Countries.

Objectives: The COVID-19 pandemic is having an unprecedented detrimental impact on mental health in people around the world. It is important therefore to explore factors that may buffer or accentuate the risk of mental health problems in this context. Given that compassion has numerous benefits for mental health, emotion regulation, and social relationships, this study examines the buffering effects of different flows of compassion (for self, for others, from others) against the impact of perceived threat of COVID-19 on depression, anxiety, and stress, and social safeness.

How do we best synergize climate mitigation actions to co-benefit biodiversity?

A multitude of actions to protect, sustainably manage and restore natural and modified ecosystems can have co-benefits for both climate mitigation and biodiversity conservation. Reducing greenhouse emissions to limit warming to less than 1.5 or 2°C above preindustrial levels, as outlined in the Paris Agreement, can yield strong co-benefits for land, freshwater and marine biodiversity and reduce amplifying climate feedbacks from ecosystem changes.

The role of social connection on the experience of COVID-19 related post-traumatic growth and stress.

Background: Historically social connection has been an important way through which humans have coped with large-scale threatening events. In the context of the COVID-19 pandemic, lockdowns have deprived people of major sources of social support and coping, with others representing threats. Hence, a major stressor during the pandemic has been a sense of social disconnection and loneliness.

Areas of global importance for conserving terrestrial biodiversity, carbon and water.

To meet the ambitious objectives of biodiversity and climate conventions, the international community requires clarity on how these objectives can be operationalized spatially and how multiple targets can be pursued concurrently. To support goal setting and the implementation of international strategies and action plans, spatial guidance is needed to identify which land areas have the potential to generate the greatest synergies between conserving biodiversity and nature's contributions to people. Here we present results from a joint optimization that minimizes the number of threatened species, maximizes carbon retention and water quality regulation, and ranks terrestrial conservation priorities globally.

Mining for Perchlorate Resistance Genes in Microorganisms From Sediments of a Hypersaline Pond in Atacama Desert, Chile.

Perchlorate is an oxidative pollutant toxic to most of terrestrial life by promoting denaturation of macromolecules, oxidative stress, and DNA damage. However, several microorganisms, especially hyperhalophiles, are able to tolerate high levels of this compound. Furthermore, relatively high quantities of perchlorate salts were detected on the Martian surface, and due to its strong hygroscopicity and its ability to substantially decrease the freezing point of water, perchlorate is thought to increase the availability of liquid brine water in hyper-arid and cold environments, such as the Martian regolith.
