RESUMEN

El paradigma de apoyos y el de calidad de vida se han transformado en guías fundamentales para los avances en el ámbito de la discapacidad intelectual (DI). Con base en una muestra de 93 personas adultas con DI, se analiza, desde un enfoque cuantitativo no experimental, la relación entre la calidad de vida y las necesidades de apoyo, aplicando la escala INICO-FEAPS y la escala de Intensidad de Apoyos (SIS) para cada constructo. Los principales resultados evidencian que existe una relación fuerte e indirecta entre calidad de vida y necesidades de apoyos, y también la relevancia de analizar dichos resultados desde variables como grado de discapacidad, sexo o nivel socioeconómico. La discusión permite inferir la necesidad de discutir nuevas estrategias en torno a categorías como el grado de discapacidad, la autodeterminación e inclusión social, como elementos facilitadores de la calidad de vida y apoyos desde un enfoque integral que contribuya al desarrollo de estrategias de programas sociales para la población con DI.

RESUMEN

Chilean peach growers have achieved worldwide recognition for their high-quality fruit products. Among the main factors influencing peach fruit quality, sweetness is pivotal for maintaining the market's competitiveness. Numerous studies have been conducted in different peach-segregating populations to unravel SSC regulation. However, different cultivars may also have distinct genetic conformation, and other factors, such as environmental conditions, can significantly impact SSC. Using a transcriptomic approach with a gene co-expression network analysis, we aimed to identify the regulatory mechanism that controls the sugar accumulation process in an 'O × N' peach population. This population was previously studied through genomic analysis, associating LG5 with the genetic control of the SSC trait. The results obtained in this study allowed us to identify 91 differentially expressed genes located on chromosome 5 of the peach genome as putative new regulators of sugar accumulation in peach, together with a regulatory network that involves genes directly associated with sugar transport (PpSWEET15), cellulose biosynthesis (PpCSLG2), flavonoid biosynthesis (PpPAL1), pectin modifications (PpPG, PpPL and PpPMEi), expansins (PpEXPA1 and PpEXPA8) and several transcription factors (PpC3H67, PpHB7, PpRVE1 and PpCBF4) involved with the SSC phenotype. These results contribute to a better understanding of the genetic control of the SSC trait for future breeding programs in peaches.

RESUMEN

BACKGROUND: The number of people with palliative care needs is projected to increase globally. Chile has recently introduced legislation for universal access to palliative care services for patients with severe and terminal illnesses, including non-cancer conditions. We aimed to estimate the number of people affected by serious health-related suffering and need for palliative care in Chile to 2050. METHODS: We used data on all deaths registered in Chile between 1997-2019 and population estimates for 1997-2050. We used Poisson regression to model past trends in causes of death adjusted by age, sex and population estimates, to project the number of deaths for each cause from 2021 to 2050. We applied the Lancet Commission on Palliative Care and Pain Relief weights to these projections to identify decedents and non-decedents with palliative care needs. RESULTS: Population palliative care needs in Chile are projected to increase from 117 (95% CI 114 to 120) thousand people in 2021 to 209 (95% CI 198 to 223) thousand people in 2050, a 79% increase (IRR 1.79; 95% CI 1.78-1.80). This increase will be driven by non-cancer conditions, particularly dementia (IRR 2.9, 95% CI 2.85-2.95) and cardiovascular conditions (IRR 1.86, 95% CI 1.83-1.89). By 2050, 50% of those estimated to need palliative care will be non-decedents (not expected to die within a year). CONCLUSIONS: Chile will experience a large increase in palliative care needs, particularly for people with dementia and other non-cancer conditions. Improved availability of high-quality services, expanded clinician training and new sustainable models of care are urgently required to ensure universal access to palliative care.

RESUMEN

Seawater desalination is one of the most feasible technologies for producing fresh water to address the water scarcity scenario worldwide. However, environmental concerns about the potential impact of brine discharge on marine ecosystems hinder or delay the development of desalination projects. In addition, scientific knowledge is lacking about the impact of brine discharges on the South America Pacific coast where desalination, is being developed. This paper presents the first monitoring results of brine discharge influence areas from seawater reverse osmosis desalination plants (SWRO) on the South America Pacific coast, using Chile as case study. Our results indicate that the combination of favorable oceanographic conditions and diffusers, results in the rapid dilution of brine discharge on coastal ecosystems; showing a faster dilution than other SWRO plants in other regions, such as Mediterranean or Arabian Gulf, with similar production characteristics. Also, the increase in salinity over the natural salinity in the brine-discharge-affected area was <5 % in a radius of <100 m from the discharge points. Further, according to the published literature and on our monitoring results, we propose a number of considerations (environmental regulation, best scientifically tested measures, environmental requirements) to achieve a long-term sustainable desalination operation.

RESUMEN

This study explores how the Household Dietary Diversity Score (HDDS) and spatial visualization can inform food governance in Chile, focusing on socio-demographic and geographical determinants affecting food consumption patterns. A national household database (n = 4047), including households from 2019 (n = 3967; 98.02%) and 2020 (n = 80; 1.98%), provided by the "Family Support Program of Food Self-Sufficiency" (FSPFS) of the Ministry of Social Development and Family, was analyzed. The findings revealed that Chilean vulnerable households were led mostly by women (86.6%), with an age average of 55.9 ± 15.6 years old, versus 68.9 ± 12.9 years in the case of men. The intake frequency analysis showed that dairy, fruits, and vegetables were below the recommended values in at least half of the households, and that fats and sugars were above recommended levels. Regarding the HDDS (0-189), the national average was 91.4 ± 20.6 and was significantly influenced by the number of minors in the households, water access, food access issues, and residing in the Zona Sur. Finally, the spatial visualization showed that the Zona Central had higher consumption of fruits and vegetables, while the extreme zones Norte Grande and Zona Austral showed higher intakes of fats and sugars. These findings emphasize the importance of leveraging data insights like the HDDS and spatial visualization to enhance food security and inform food governance strategies.

RESUMEN

BACKGROUND: The comorbidity between obesity and smoking and its association with cardiometabolic risk factors has been little explored. OBJECTIVES: Describe the prevalence of such comorbidity and to explore its association with cardiometabolic risk factors. METHODS: The study was based on the 2016-2017 Chilean National Health Survey and included 6,233 participants. The independent variables were general obesity according to Body Mass Index (BMI), central obesity measured by Waist-to-Height Ratio (WTHR) and Waist Circumference (WC), and daily tobacco consumption (DTC). The dependent variables were blood lipids, fasting glucose and blood pressure. The association analysis was performed by multivariate logistic regression and excluded subjects with a medical record of hypertension, diabetes mellitus and dyslipidemia to avoid reverse causality. RESULTS: The prevalence of General obesity-DTC comorbidity was 7.7%, WTHR risk-DTC was 10.8% and elevated WC-DTC was 13.2%. A total of 3,132 participants were included in logistic regressions. General obesity alone, and DTC-general obesity comorbidity had statistically significant association with elevated triglycerides, decreased HDL, elevated non-HDL and total cholesterol, elevated fasting glucose, and elevated blood pressure. The comorbidities DTC-risk WTHR and DTC-increased WC were associated with increased triglycerides and non-HDL cholesterol. DTC alone was associated with elevated systolic blood pressure. CONCLUSION: DTC-general obesity comorbidity is more frequently associated with the cardiometabolic risk factors explored than DTC-central obesity comorbidity. Smoking cessation can be a cost-effective intervention in this risk comorbidity.

RESUMEN

BACKGROUND: One of the main limitations to achieving a complete tumor resection in patients with technically resectable liver tumors is the presence of a small future liver remnant (FLR). Portal vein embolization (PVE) allows hypertrophy of the non-embolized lobe, reducing the risk of postoperative liver failure. AIM: To describe the experience of portal embolization prior to hepatectomy and its effectiveness in converting advanced unresectable liver tumors into resectable tumors. METHODS: Non-concurrent cohort study. All patients who underwent PVE before hepatectomy between 2016 and 2020 in our center were included. Demographic and diagnostic variables, pre and post-PVE volumes, perioperative variables, and global and disease-free survival were analyzed. RESULTS: Nineteen patients were included. Median age 66 (54-72) years and 57.9% (n= 11) were women. Bilateral metastases were present in 78.9% (n= 15). Sixteen patients (84.2%) received neoadjuvant chemotherapy. One patient (5.3%) had a complication after PVE. The median time between embolization and volumetry was 5.3 weeks (4.7-7.1). Median FLR before and after PVE were 19.8% (16.2-27.7) and 30% (25.2-40.5), respectively. The median percentage of hypertrophy was 48% (40.4-76.5). Fifteen patients (78.9%) underwent hepatectomy. Significant complications occurred in 26.6% (n= 4); among them, three patients (20%) presented postoperative liver failure. CONCLUSIONS: PVE is safe and effective in promoting FLR hypertrophy in the presence of chemotherapy, allowing patients with advanced liver tumors to undergo surgery with curative intent.

RESUMEN

INTRODUCTION: The COVID-19 pandemic marked a milestone in the history of medicine worldwide. Together with the humanitarian drama it represented, the problems that arose are promoting lines of research in multiple fields. One of these fields is the aspects related to medical communication and end-of-life care. This paper reports the experiences and perceptions of relatives of patients who died during the pandemic with a psychospiritual support intervention in a public hospital in the Metropolitan Region, Chile, called "farewell". METHODS: A qualitative study was conducted with a phenomenological approach based on in-depth interviews. From this, categories were derived that allowed a systematization of the observation of the experiences. RESULTS: Among the results, the impact of the circumstances and the communication provided by the medical team on grief should be highlighted. The use of the word "farewell" emerges as a useful, albeit ambiguous, communicative tool when it comes to adequately framing an end-of-life process. CONCLUSIONS: It is argued that the end of life is an area that requires physical and psychospiritual spaces, and adequate training at all levels to do justice to a highly relevant moment in the care of people.

RESUMEN

ABASTRACT Background: To study the association between pain and depression, its characteristics and related factors in chilean older adults. METHODS: Cross-sectional analytical study of the National Survey of Dependence in Chilean older adults 2009, with a sample of 4766 people aged 60 years and older. Pain was described using a Likert scale from "no pain" to "very much pain". Depression was measured using the GDS-15 scale. Adjusted logistic regression analyses were performed to identify the association between pain and depression. RESULTS: 70% of the sample reported pain, 21.6% of high intensity. The screening was positive for depression in 23% of the sample, and 5% suspected severe depression. Both conditions were more frequent in women, subjects with low levels of schooling and rural residence. There was an association between pain and depression OR 3.46. The greater the intensity of pain, the greater the association OR 5.2 (95% CI 4.1-6.7) for depressive symptoms and OR 13.9 for suspected severe depression (95% CI 8.1-23.9). CONCLUSION: The association between pain and depression is high and is related to pain intensity, being higher in people with less education and physical dependency. The high frequency of both conditions in Chilean elderly people and their serious consequences make it an urgent public health problem, aggravated as a consequence of the prolonged isolation due to the COVID-19 pandemic.

RESUMEN

BACKGROUND: Empathy is a fundamental element of the physician-patient relationship for treatment and therapeutic adherence that has had to face significant changes due to the migrations of the health system in Chile. AIM: Characterize the empathetic physicians according to the perceptions of chronic patients during the encounter with national and foreign doctors in the public health system in the Maule Region. METHODS: Qualitative study of exploratory-descriptive type. Twenty chronic patients from public health services in the Maule region were interviewed remotely using the free listing technique. A thematic processual qualitative analysis of the content and a descriptive quantitative analysis were carried out where the frequency and salience of the Smith index assisted by the Anthropac 4.98 software were obtained. RESULTS: Seven categories of empathetic care were identified in the physicians-patient relationship: Affectivity (37%), Communication (19%), Attention (13%), Respect (12%), Research (9%), Knowledge (5%) and Efficiency (5%). CONCLUSIONS: The affective and psychoemotional aspects were more valued than the cognitive aspects of empathetic care. No differences were observed in assessing the empathetic care of patients seen by Chilean physicians and those treated by foreign physicians.

RESUMEN

INTRODUCTION: The Cardiovascular Health Program (PSCV), founded by the Ministry of Health of Chile (Minsal), is focused on the global cardiovascular risk of people with the purpose of preventing and reducing morbidity, disability and premature death caused by cardiovascular diseases, in congruence with its sanitary aims. Quaternary Prevention is defined as "actions taken to protect individuals from medical interventions that are likely to cause more harm than good". The PSVC's 2017 technical guidelines establish a battery of 11 complementary exams to request upon entering the program, however, neither the scientific evidence that supports them nor the periodicity of their request was mentioned. The aim of this revision is to evaluate the rationality of exams request, based on updated evidence, as a strategy for quaternary prevention and potential economic savings for the sanitary system. METHODS: A narrative review was conducted through searches on databases, updated clinical guidelines and international recommendations about 11 complementary exams on the follow-up of Type 2 Diabetes and Hypertension. RESULTS: Based on the data analysis, recommendations were made according to the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system. CONCLUSION: It was concluded that the costs of widely requested complementary exams could be reduced through a more efficient management guided by updated evidence. Our proposal entails changes in some processes and in the evaluation of fulfillment of the PSCV, as well as a deeper cost-effectiveness analysis of the recommendations in order to optimize the management of resources in primary health care.

RESUMEN

Obstructive sleep apnea syndrome (OSAS) is associated with cardiovascular risk factors that comprise metabolic syndrome, including central obesity, hypertension, insulin resistance, impaired glucose tolerance, and dyslipidaemia. AIM: To assess metabolic syndrome prevalence in adult patients with OSAS. METHODS: We administered a standardized clinical questionnaire and four sleep questionnaires (Berlin, Epworth Sleepiness Scale, STOP, and STOP-Bang), and measured anthropometric variables. We also measured serum glucose and lipids, and blood pressure following an overnight fast. Metabolic syndrome was diagnosed according to National Cholesterol Education Program criteria. Patients underwent an overnight ambulatory respiratory polygraphy to confirm the diagnosis of OSAS. The predictive variables were subjected to univariate and multivariate analysis in a logistic regression model. RESULTS: Of 1,030 screened patients, 68% were male, 92% had comorbidities and 58% had moderate-severe OSAS. Subjects with OSAS were more obese, had higher cervical and waist circumference, blood pressure and fasting serum glucose, had lower HDL cholesterol, and an increased incidence of metabolic syndrome (55.4% vs. 44.8%, p<0.013). Age, male sex, hypertension, body mass index, cervical, waist and hip circumferences, intense snoring, witnessed apnea, nocturia, and components of metabolic syndrome were associated with the risk of OSAS and its severity. Fasting blood glucose, blood pressure, and waist circumference were associated with the risk of moderate or severe OSAS, which was not significant for the alteration of blood lipids. CONCLUSION: Patients with OSAS have a high prevalence of metabolic syndrome. OSAS was associated with an increase in the cardiovascular risk factors that comprise the metabolic syndrome.

RESUMEN

AIM: To explore the perceptions and experiences of COVID-19 patients who received outpatient treatment in public health services in the Metropolitan Region of Chile. METHODS: An exploratory rapid qualitative study was conducted. Individual, telephonic and semi-structured interviews were conducted with patients who received a COVID-19 diagnosis confirmed by a PCR test and who had outpatient treatment for the disease. A thematic analysis was performed. RESULTS: Nine interviews were conducted (six female and three male participants). The main emerging themes were: life before COVID-19, living with the disease at home, recovery process, and Ineffective sanitary measures. Most of the participants highlighted the lack of information about their health and the uncertainty about COVID-19 as the cause of fear for their wellbeing. They also felt guilty for putting at risk others due to their COVID-19-positive status. CONCLUSION: The experiences of patients show the need to strengthen communication and information strategies for patients who receive outpatient care during the pandemic. This is key to reducing misinformation, fear and uncertainty about the progression of the disease and the potential recovery. Consequently, this could impact clinical outcomes and patient satisfaction.

RESUMEN

BACKGROUND: Sexual violence has a several negative impact on women's health. Thus, the health system is a gateway for the multisector response to victims. In 2018, the Clinical Forensic Hospital Units (UCFH) in Chile were launched for this purpose. OBJECTIVE: To evaluate the state of implementation of the UCFH in the health services (HS) in Chile. METHOD: This is a quantitative descriptive, cross-sectional study. A survey was designed and applied through the Google Forms platform to the managers of the care and prevention network for victims of sexual violence (VSV) of each SS. The contact of each manager was requested by each HS in three ways: transparency law, lobby law, and telephone. Each HS was classified according to the existence or not of UCFH and for each unit the availability of resources was evaluated according to the recommendations of the Technical Standard of Attention to VSV of the Ministry of Health. Also, the functioning of each unit during the pandemic was evaluated. RESULTS: Twenty-four of the 29 HSs responded, of which 12 reported having UCFH. Of the 12 units, 50% had complete infrastructure, 58.3% had complete instruments, none had full human resources, 50% had partial HR, 50% had sampling complete, and 58. 3% had full health benefits. The function during the pandemic was affected in 25% of the units. CONCLUSION: Challenges persist in the implementation of the UCFH, with special limitations in the availability of human resources.

RESUMEN

BACKGROUND: Food environments are crucial for promoting healthy and sustainable eating and preventing obesity. However, existing food environment frameworks assume an already installed causality and do not explain how associations in food environments are established or articulated, especially from an integrative and transdisciplinary approach. This research attempts to bridge these gaps through the use of Actor-Network Theory, which traces the relationship network between human (and nonhuman) actors in order to describe how these interact and what agencies (direct or remote) are involved. OBJECTIVE: This study aims to explain the practices and interactions of actors in food environments in order to approach the problem of unhealthy eating with a transdisciplinary approach. METHODS: This is a nonexperimental, cross-sectional study. Due to the complexity of the study phenomena, a mixed methods approach with 4 consecutive phases will be developed in Chile. Phase 1 involves a systematic literature review of food environment evidence since 2015, following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) protocol; phase 2 involves the application of a shortened version of the Nutrition Environment Measure Scale-Perceptions adapted to Chile (NEMS-P-Ch) in 2 neighborhoods with different socioeconomic levels; in phase 3, six focus groups in each neighborhood will be conducted to address social determinants such as gender, employment status, and migration; and in phase 4, participant observation and in-depth interviews will be used to analyze the direct and empirical exploration of the actors in their daily interaction with food environments. The triangulation and complementarity of the data will allow us to create a practical model about the practices and interactions of actors in their food environments, which reflects the complexity and transdisciplinary nature of the study. RESULTS: We have advanced in phases 1-3 of the study. In phase 1, a total of 109 manuscripts are being revised for data extraction. In phase 2, we applied the NEMS-P-Ch to 785 people, 49.4% (388/785) of whom belong to a low socioeconomic neighborhood. Participants from phase 2 are being contacted to participate in the focus groups (phase 3). By the end of July, we have conducted 6 focus groups with 5-11 participants. CONCLUSIONS: This study will provide a comprehensive understanding of how individuals interact with their food environments, offering deep insights into the factors influencing their food-related decisions. In addition, the study aims to develop a model that more accurately reflects reality by examining not only the food environments themselves but also the interactions among various stakeholders within these environments and their daily practices. The findings of this study will offer evidence-based insights to inform public policies tailored to the specific territories and communities under investigation or those with similar characteristics.
