Forensic and legal medicine in Chile: Cinderella without a prince.

Forensic medicine is of enormous importance in the functioning of contemporary justice systems worldwide. Therefore, in order to characterize the current state of medicolegal and forensic activity in Chile, a non-systematic review of the biomedical and legal literature on the subject was carried out. An analysis of open sources of information was also incorporated, including the National Registry of Individual Health Care Providers, the latest public accounts of the Forensic Medical Service, relevant background information available on the active transparency portal of that institution, exempt resolutions included in the "Chile Law" database (of the Department of Legislative and Documentary Services of the Library of the National Congress) and the lists of judicial experts appointed by the Courts of Appeals of the country for the biennium 2024 to 2025. We note that Chile maintains an unacceptable historical debt in terms of academic development and training of qualified professionals in forensic matters. Likewise, national scientific productivity in this field is practically null. Currently, forensic medicine is the medical specialty with the deepest shortage of professionals nationwide. Consequently, as in the early part of the last century, medical expert opinions are frequently performed by professionals untrained in forensic medicine. This scenario, taking into account the attitudes of certain lawyers and judges (detailed in the article), increases the risk of a miscarriage of justice. National public policies must take urgent action to address the deficits and provide solutions.

Climatological Aspects of Notable Tornado Events in Chile

Abstract Tornadoes in Chile seem to develop in what are called “high-shear, low-CAPE” (HSLC) environments. An analysis of convective parameters from the ERA5 reanalysis during 16 notable tornadoes in Chile showed that several increased markedly before the time of the reports. The significant tornado parameter (STP) was able to discriminate the timing and location of the tornadoes, even though it was not created with that goal. We established thresholds for the severe hazards in environments with reduced buoyancy (SHERBE) parameter (≥1) and the STP (≤−0.3) to further identify days favorable for tornado activity in Chile. The SHERBE and STP parameters were then used to conduct a climatological analysis from 1959 to 2021 of the seasonal, interannual, and latitudinal variations of the environments that might favor tornadoes. Both parameters were found to have a strong annual cycle. The largest magnitudes of STP were found to be generally confined to south-central Chile, in agreement with the (sparse) tornado record. The probability of a day with both SHERBE and STP values beyond their thresholds was greatest between May and August, which aligns with the months with the most tornado reports. The number of days with both SHERBE and STP beyond their respective thresholds was found to fluctuate interannually. This result warrants further study given the known interannual variability of synoptic and mesoscale weather in Chile. The results of this study extend our understanding of tornado environments in Chile and provide insight into their spatiotemporal variability.

Settlement of Chilean Flat Oysters (Ostrea chilensis) on Ribbed Mussel Shell Collectors for Commercial Grow-Out: Towards Sustainable Management

Ostrea chilensis (a flat oyster) is native to Chile and New Zealand. In Chile, this oyster has been cultured and harvested for at least 80 years. However, the culture of flat oysters has not developed like other aquaculture activities in Chile, mainly due to the inefficiency of the collectors (made of ribbed mussel shells) and the lack of spats produced. The objective of this study was to determine the capacity of spat collectors for the settlement of O. chilensis. For this purpose, field and laboratory experiments were carried out. Our results indicated that oyster larvae do not have a preference for either side of the shell (periostracum or nacreous) to settle on. However, after one year of growth in the field, juveniles were more abundant on the nacreous side of the shell (spat collector). Also, the oysters that settled on the nacreous side of the valve were larger. This was due to the fact that the periostracum had a greater number of epibionts, and they competed for space and resources with the settled oyster spats, causing a decrease in the abundance of oyster spats on that surface. Our findings raise the possibility that collectors could improve efficiency in the production of spats. Finally, we discuss the implications of these results for the Chilean oyster-farming industry.

Preventable incidence cases from non-communicable diseases attributable to insufficient physical activity in Chile

ObjectivesLack of sufficient physical activity (PA) has been associated with an increased risk of several non-communicable diseases (NCDs) and all-cause mortality. This study aimed to estimate the number of preventable incidence cases of NCDs attributable to insufficient PA in the Chilean population. Study designComparative risk assessment modelling study. MethodsThis study examined data from 5834 participants aged ≥20 years from the Chilean National Survey (2016–2017). PA was assessed by the Global Physical Activity Questionnaire (GPAQ), and metabolic equivalent of tasks (METs) were assigned according to PA intensity. Estimated incidence cases of NCDs in Chile in 2019 were obtained from the Global Burden of Disease study. Relative risks for breast cancer, colon cancer, ischaemic heart disease, diabetes and stroke were obtained from a published meta-analysis and applied to the prevalence of insufficient PA estimates through the potential impact fraction equation. ResultsHigh levels of PA (≥8000 MET-min/week) could potentially avoid more than 22,000 (64.6 %) incidence NCD cases, ranging from 498 (10.1 %) preventable cases of breast cancer to 5629 (14.7 %) cases of diabetes. Other modelled scenarios also showed to reduce the incidence cases of all five NCDs but to a lesser extent; where at least PA recommendation was achieved, preventable NCDs were reduced by 6522 cases (18.7 %), and where a 10 % relative reduction in insufficient PA level in the population was achieved, preventable NCDs were reduced by 651 (1.8 %) cases. ConclusionsThe study results provide estimates for the incidence cases of preventable NCDs attributable to insufficient PA, highlighting the important role of PA in NCD prevention in Chile.

Mobilization of persistent organic pollutants in humpback whales: Insights from feeding areas in the Antarctic peninsula and Strait of Magellan to migration, breeding, and calving grounds along the Brazilian coast

Southern Hemisphere Megaptera novaeangliae undertake the longest migration, which reflect their exposure to lipophilic contaminants. To assess these changes, persistent organic pollutants were analyzed in blubber samples of humpback whales from three regions: the Antarctic Peninsula (n = 46), the Strait of Magellan, Chile (n = 22), and the Brazilian coast (n = 38). The similarity in PCB and HCB levels between individuals from feeding grounds and breeding grounds suggests contamination during feeding. The whales around the Antarctic Peninsula exhibited a predominance of tetrachlorobiphenyl PCBs. Whales feeding in the Strait of Magellan showed a slight prevalence of 5Cl biphenyls, likely due to their consumption of subantarctic krill species as well as small fishes potentially contaminated by industrial activities in Chile. The dominance of 5-6Cl congeners in whales in Brazil, may be attributed to the extreme physiological changes during fasting when whales utilize blubber reserves and metabolize lighter congeners, or transfer them to their calves.

Territorial Infrastructure Support Index (ISIT)

Through a review of the literature on infrastructure, a study of international experiences, expert knowledge, and the elaboration of a Territorial Infrastructure Support Index (ISIT), this paper provides a comparative analysis of the development conditions -- regarding infrastructure and services -- for the location of productive economic activities, at the regional and provincial level in Chile. The results show contrasts between regions and within them, revealing the state of the current situation for each of the six dimensions: Water, Energy, Telecommunications, Roads, Logistics, and Resilience, as well as for their synthetic indicator ISIT. The results of the ISIT have been contrasted with the recent definitions made by the Government of Chile regarding the definition of lag zones, finding important coincidences at the provincial level that allow validating the ISIT as a tool for the analysis of gaps in infrastructure and equipment for development of economic and productive activities in Chile.

Priority pesticides in Chile: Predicting their environmental distribution, bioaccumulation, and transport potential.

Agriculture is one of the main economic activities in Chile and is associated with extensive use of pesticides, which can represent a risk to the environment and to human health. Currently, there are over 400 pesticides approved for commerce in Chile, including chemicals banned in other countries (e.g., flocoumafen and chlorfenapyr). An empirical analysis of their potential environmental effects is difficult due to this large number, thus opening the doors for the use of computational tools for prioritization efforts based on their persistence, bioaccumulation, and transport potential in the environment. The main objectives of this study were to estimate the properties and environmental distribution of pesticides approved for commerce in Chile and to generate a priority list for further evaluation in local environments. We used the Estimation Program Interface Suite interface to estimate the distribution coefficients, half-lives, and bioaccumulation potential of all pesticides registered in the Chilean Agriculture and Livestock Services. Additionally, the Pov & LRTP Screening Tool was used to estimate their overall persistence and long-range transport potential in the environment. The results were used to develop a P-B-lon range transport (LRT) score, which considered persistence, bioaccumulation, and long-range transport potential. All pesticides were compared to a group of polychlorinated biphenyls (PCBs), used as reference compounds, to generate a list of priority pesticides with persistent organic pollutants characteristics. The results showed that most pesticides were distributed between the organic phase and water, where they also showed the longest half-lives and bioaccumulation potential. A group of 21 pesticides showed relatively high P-B-LRT scores, compared to PCBs, and were classified as priority compounds. The list was further refined based on the volume of sales for each pesticide.Integr Environ Assess Manag 2023;19:676-683. © 2022 The Authors.

Work/household, transport, and leisure domains account for the sex gap in physical activity in Chile.

BackgroundWomen usually have lower levels of moderate-vigorous physical activity (MVPA) than men. This sex gap can be accounted for by differences in MVPA in the work/household, transport, and/or leisure domains. Identifying where the differences lay in a context-specific manner may help close the gap. We aimed to compare MVPA by domain, and the relative contribution of each domain to total MVPA, between men and women in Chile.MethodsWe analyzed the cross-sectional National Health Survey of Chile 2016–2017 (n = 5,056, 64% women, ≥18 years old). MVPA was estimated with the Global Physical Activity Questionnaire. MVPA was expressed in MET × min/week, and the relative contribution to total MVPA by each domain was expressed as percentage. Analyses were conducted including all participants, and also including participants reporting >0 MET × min/week of MVPA (relative contributions can only be computed in the latter).ResultsIncluding all participants, women (vs. men) had lower MVPA (median [25–75th percentile]) for work/household (0 [0–960] vs. 0 [0–5,760] MET × min/week), for transport (360 [0–1,200] vs. 600 [0–1,680] MET × min/week), and for leisure domains (0 [0–0] vs. 0 [0–480] MET × min/week). Including only participants with >0 MET × min/week of MVPA, women (vs. men) had lower mean relative contributions to total MVPA from work/household (31.3 vs. 35.9%) and leisure domains (10.8 vs. 16.3%, respectively), but higher from the transport domain (57.9 vs. 47.8%).ConclusionIn Chile, differences in all physical activity domains account for the sex gap in MVPA. Strategies to break job stereotypes, increase opportunities for leisure, and ease active transport are required to encourage MVPA in women.

Health Status of Mytilus chilensis from Intensive Culture Areas in Chile Assessed by Molecular, Microbiological, and Histological Analyses.

Shellfish farming is a relevant economic activity in Chile, where the inner sea in Chiloé island concentrates 99% of the production of the mussel Mytilus chilensis. This area is characterized by the presence of numerous human activities, which could harm the quality of seawater. Additionally, the presence of potentially pathogenic microorganisms can influence the health status of mussels, which must be constantly monitored. To have a clear viewpoint of the health status of M. chilensis and to study its potential as a host species for exotic diseases, microbiological, molecular, and histological analyses were performed. This study was carried out in October 2018, where M. chilensis gut were studied for: presence of food-borne bacteria (Vibrio parahaemolyticus, Escherichia coli, Salmonella spp.), exotic bacteria (“Candidatus Xenohaliotis californiensis”), viruses (abalone and Ostreid herpes virus), and protozoa (Marteilia spp., Perkinsus spp. and Bonamia spp.). Additionally, 18S rDNA metabarcoding and histology analyses were included to have a complete evaluation of the health status of M. chilensis. Overall, despite the presence of risk factors, abnormal mortality rates were not reported during the monitoring period and the histological examination did not reveal significant lesions. Pathogens of mandatory notification to World Organization for Animal Health (OIE) and the Chilean National Fisheries and Aquaculture Service (SERNAPESCA) were not detected, which confirms that M. chilensis have a good health status, highlighting the importance of an integrated vision of different disciplines to ensure the sustainability of this important mussel industry in Chile.

High-resolution inventory of atmospheric emissions from transport, industrial, energy, mining and residential activities in Chile

Abstract. This study presents the first high-resolution national inventory of anthropogenic emissions for Chile (Inventario Nacional de Emisiones Antropogénicas, INEMA). Emissions for the vehicular, industrial, energy, mining and residential sectors are estimated for the period 2015–2017 and spatially distributed onto a high-resolution grid (approximately 1 km×1 km). The pollutants included are CO2, NOx, SO2, CO, VOCs (volatile organic compounds), NH3 and particulate matter (PM10 and PM2.5) for all sectors. CH4 and black carbon are included for transport and residential sources, while arsenic, benzene, mercury, lead, toluene, and polychlorinated dibenzo-p-dioxins and furan (PCDD/F) are estimated for energy, mining and industrial sources. New activity data and emissions factors are compiled to estimate emissions, which are subsequently spatially distributed using census data and Chile's road network information. The estimated annual average total national emissions of PM10 and PM2.5 during the study period are 191 and 173kt a−1 (kilotons per year), respectively. The residential sector is responsible for over 90 % of these emissions. This sector also emits 81 % and 87 % of total CO and VOC, respectively. On the other hand, the energy and industry sectors contribute significantly to NH3, SO2 and CO2 emissions, while the transport sector dominates NOx and CO2 emissions, and the mining sector dominates SO2 emissions. In general, emissions of anthropogenic air pollutants and CO2 in northern Chile are dominated by mining activities as well as thermoelectric power plants, while in central Chile the dominant sources are transport and residential emissions. The latter also mostly dominates emissions in southern Chile, which has a much colder climate. Preliminary analysis revealed the dominant role of the emission factors in the final emission uncertainty. Nevertheless, uncertainty in activity data also contributes as suggested by the difference in CO2 emissions between INEMA and EDGAR (Emission Database for Global Atmospheric Research). A comparison between these two inventories also revealed considerable differences for all pollutants in terms of magnitude and sectoral contribution, especially for the residential sector. EDGAR presents larger emissions for most of the pollutants except for CH4 and PM2.5. The differences between both inventories can partly be explained by the use of different emission factors, in particular for the residential sector, where emission factors incorporate information on firewood and local operation conditions. Although both inventories use similar emission factors, differences in CO2 emissions between both inventories indicate biases in the quantification of the activity. This inventory (available at https://doi.org/10.5281/zenodo.4784286, Alamos et al., 2021) will support the design of policies that seek to mitigate climate change and improve air quality by providing policymakers, stakeholders and scientists with qualified scientific spatially explicit emission information.

Milan Stuchlík and Mapuche: The Ethnographic Collection in the Náprstek Museum

Milan Stuchlík (1932–1980) was a renowned ethnographer, anthropologist, museologist, and academician. During his field research in Chile (1968–1973) he gathered a remarkable collection of material culture of the Mapuche ethnic group. This includes objects used for dining and food storage, textiles, simple tools, as well as artifacts associated with religious and festive life. Almost fifty years after the acquisition of this collection by the Náprstek Museum, the Stuchlík Collection is now published. Special attention is paid to the circumstances of the acquisition of the collection, the donors, and the original owners of the objects. The personality of Milan Stuchlík is also briefly introduced, with emphasis on his field research and collecting activities in Chile.

Making progress in determining quality: positional accuracy of the new 1:25,000 scale digital cartography

Abstract. The digital cartographic coverage at 1:25,000 that the Military Geographic Institute is creating has been worked on using international standards, so that it constitutes a standardized and interoperable tool, for the various areas of activity in Chile. In this context, the ISO TC 211 standards and the TDS (Topographic Data Store) data model developed by the National Geospatial-Intelligence Agency (NGA) are being used.Apart from using these standards, efforts have been aimed, from an early stage, at the determination of the quality of this product, starting this process with the study for a methodology to measure Positional Accuracy. The method defined conforms to the NSSDA test; for this, points measured in the terrain especially for this control are used, also the elimination of points that are out of range under the Chauvenet Criteria. Finally, the positional accuracy is declared in the metadata.

Class identity in times of social mobilization and labor union revitalization: Evidence from the case of Chile (2009–2019)

Over the past decade, there has been a revival of social protest and labor union activity in Chile. In this article, we examine the effects of this phenomenon to analyze its influence on working-class identity. Using International Social Survey Programme surveys from 2009 and 2019, we investigate whether class location and union membership affect people’s subjective identification with the working class and how that effect may have changed over the decade. Our findings suggest that subjects who are situated in a ‘subordinated’ class position (unskilled workers or informal self-employed workers) are more likely to identify with the working class compared to subjects located in a privileged class position (employers, experts, or managers). However, surprisingly, our analysis does not indicate that working-class identity is reinforced by union membership. In addition, our results do not demonstrate that the effect of class or union membership has strengthened over the past decade. At the end of this article, we offer some possible explanations for these findings.

A Model-Based Economic Evaluation of Cladribine Versus Alemtuzumab, Ocrelizumab and Natalizumab for the Treatment of Relapsing-Remitting Multiple Sclerosis with High Disease Activity in Chile.

PurposeThe aim of this study was to evaluate the cost effectiveness of cladribine compared with alemtuzumab, natalizumab, and ocrelizumab for the treatment of highly active multiple sclerosis (HAD-MS) from the perspective of the Chilean health care public sector.Materials and MethodsA Markov model was used to compare costs and quality-adjusted life-years (QALYs) over a 45-year time horizon using a 3% discount rate for costs and outcomes. Natural history of the disease was modeled in terms of progression of disability according to the Expanded Disability Status Scale (EDSS). A network meta-analysis was used as a source of comparative effectiveness for disability progression and annual relapse rates. Differences in costs and outcomes were modeled for only 10 years due to high temporal uncertainty. Ocrelizumab was assumed to have the same efficacy as cladribine due to lack of data. Direct costs were taken from national tariffs and expressed in 2019 US dollars. Utilities for EDSS health states were obtained from the literature. Second-order uncertainty was characterized through deterministic and probabilistic sensitivity analysis.FindingsCompared with natalizumab (the current strategy covered in Chile), cladribine is associated with incremental costs and QALYs of US$70,989 and 1.875, respectively (incremental cost-effectiveness ratio [ICER] $37,861). Ocrelizumab was extendedly dominated by cladribine and natalizumab, and alemtuzumab was dominated by cladribine. A scenario analysis of a 10% discount did not modify the results substantially, but showed a decrease in the ICER of cladribine versus natalizumab (ICER $29,833/QALY).ImplicationsCladribine is a new oral alternative to treat patients with HAD-MS that is expected to produce higher QALYs than all evaluated alternatives. In the context of a conservative analysis, cladribine cannot be considered cost effective for the Chilean health care public sector using a 1 GDP per capita threshold. However, under reasonable discount scenarios, cladribine becomes an attractive alternative for the health system.

Simplified corporations and entrepreneurship

ABSTRACT The World Bank's Doing Business project encourages the reduction of business registration requirements to stimulate entrepreneurship and economic development. Over the last two decades, it has contributed to the harmonisation of these requirements worldwide, but the rates of newly registered firms have not always followed through. Its unparalleled influence and emphasis on procedural reforms shadowed the development and comparative evaluation of alternative incentives to entrepreneurship. This article contributes to filling this gap, by empirically examining the impact of simplified corporations, legal forms designed to stimulate entrepreneurial activity in Chile and Colombia. These new corporate forms provide not only abbreviated registration and operation rules, but also single ownership and the ability to issue classes of shares, two features that remain unavailable in many jurisdictions. The results confirm that company law reforms – both procedural and substantive – are insufficient to significantly increase the annual number of newly registered firms. Still, simplified corporations have quickly become entrepreneurs’ preferred legal form in those countries, contributing to expanding new businesses’ access to external finance.

An institutional approach to the development of business angel networks in Latin American emerging countries

Purpose The purpose of the paper is to analyze the development of business angel networks (BANs) in emerging countries such as Chile and Colombia to understand how institutions affect their development. Design/methodology/approach This is a qualitative, exploratory, and descriptive study based on a comparative analysis between countries, with the BANs in Chile and Colombia as the unit of observation. The comparative analysis was made in relation with the creation, operation and sustainability of the BANs. The study interviews the partners/managers of the active networks in each of the countries, as well as key informants, totalling 12 interviews. Findings BAN activity in Chile and Colombia is quite recent, and the countries are on a similar level of development. However, in the long term, depending on how the cultural aspects evolve in both countries and the interest that the State may have in developing business angel activity, the results could be indeed different. Originality/value Business angel activity in Latin America is quite recent; nevertheless, this activity is increasing in the region. In that sense, this comparative analysis between Colombia and Chile contributes to a better understanding of business angel markets in Latin America and also to obtain better insights into the core challenges that these markets face in emerging countries due to the existence of institutional voids. This paper is a contribution for further knowledge of BANs in emerging countries’ economies from an institutional perspective.
