Improving accessibility to radiotherapy services in Cali, Colombia: cross-sectional equity analyses using open data and big data travel times from 2020.

In this study, we evaluated and forecasted the cumulative opportunities for residents to access radiotherapy services in Cali, Colombia, while accounting for traffic congestion, using a new people-centred methodology with an equity focus. Furthermore, we identified 1-2 optimal locations where new services would maximise accessibility. We utilised open data and publicly available big data. Cali is one of South America's cities most impacted by traffic congestion. METHODOLOGY: Using a people-centred approach, we tested a web-based digital platform developed through an iterative participatory design. The platform integrates open data, including the location of radiotherapy services, the disaggregated sociodemographic microdata for the population and places of residence, and big data for travel times from Google Distance Matrix API. We used genetic algorithms to identify optimal locations for new services. We predicted accessibility cumulative opportunities (ACO) for traffic ranging from peak congestion to free-flow conditions with hourly assessments for 6-12 July 2020 and 23-29 November 2020. The interactive digital platform is openly available. PRIMARY AND SECONDARY OUTCOMES: We present descriptive statistics and population distribution heatmaps based on 20-min accessibility cumulative opportunities (ACO) isochrones for car journeys. There is no set national or international standard for these travel time thresholds. Most key informants found the 20-min threshold reasonable. These isochrones connect the population-weighted centroid of the traffic analysis zone at the place of residence to the corresponding zone of the radiotherapy service with the shortest travel time under varying traffic conditions ranging from free-flow to peak-traffic congestion levels. Additionally, we conducted a time-series bivariate analysis to assess geographical accessibility based on economic stratum. We identify 1-2 optimal locations where new services would maximize the 20-min ACO during peak-traffic congestion. RESULTS: Traffic congestion significantly diminished accessibility to radiotherapy services, particularly affecting vulnerable populations. For instance, urban 20-min ACO by car dropped from 91% of Cali's urban population within a 20-min journey to the service during free-flow traffic to 31% during peak traffic for the week of 6-12 July 2020. Percentages represent the population within a 20-min journey by car from their residence to a radiotherapy service. Specific ethnic groups, individuals with lower educational attainment, and residents on the outskirts of Cali experienced disproportionate effects, with accessibility decreasing to 11% during peak traffic compared to 81% during free-flow traffic for low-income households. We predict that strategically adding sufficient services in 1-2 locations in eastern Cali would notably enhance accessibility and reduce inequities. The recommended locations for new services remained consistent in both of our measurements.These findings underscore the significance of prioritising equity and comprehensive care in healthcare accessibility. They also offer a practical approach to optimising service locations to mitigate disparities. Expanding this approach to encompass other transportation modes, services, and cities, or updating measurements, is feasible and affordable. The new approach and data are particularly relevant for planning authorities and urban development actors.

Oropouche fever cases diagnosed in Italy in two epidemiologically non-related travellers from Cuba, late May to early June 2024.

Oropouche fever is caused by Oropouche virus (OROV), transmitted primarily through the bite of infected midges, particularly of the genus Culicoides. The virus is mainly circulating in Central and South America where several countries reported an ongoing outbreak. We report here two imported cases of OROV infection identified in Italy, late May-early June 2024. These cases indicate that in the shadow of a massive dengue outbreak in the Americas, the Oropouche outbreak might be more widespread than previously estimated.

Health care accessibility and mobility in breast cancer: a Latin American perspective.

BACKGROUND: Latin America (LATAM) encompasses a vast region with diverse populations. Despite publicly funded health care systems providing universal coverage, significant socioeconomic and ethno-racial disparities persist in health care access across the region. Breast cancer (BC) incidence and mortality rates in Brazil are comparable to those in other LATAM countries, supporting the relevance of Brazilian data, with Brazil's health care policies and expenditures often serving as models for neighboring countries. We evaluated the impact of mobility on oncological outcomes in LATAM by analyzing studies of patients with BC reporting commuting routes or travel distances to receive treatment or diagnosis. METHODS: We searched MEDLINE (PubMed), Embase, Cochrane CENTRAL, LILACS, and Google Scholar databases. Studies eligible for inclusion were randomized controlled trials and observational studies of patients with BC published in English, Portuguese, or Spanish and conducted in LATAM. The primary outcome was the impact of mobility or travel distance on oncological outcomes. Secondary outcomes included factors related to mobility barriers and access to health services. For studies meeting eligibility, relevant data were extracted using standardized forms. Risk of bias was assessed using the Newcastle-Ottawa Scale. Quantitative and qualitative evidence synthesis focused on estimating travel distances based on available data. Heterogeneity across distance traveled or travel time was addressed by converting reported travel time to kilometers traveled and estimating distances for unspecified locations. RESULTS: Of 1142 records identified, 14 were included (12 from Brazil, 1 from Mexico, and 1 from Argentina). Meta-analysis revealed an average travel distance of 77.8 km (95% CI, 49.1-106.48) to access BC-related diagnostic or therapeutic resources. Nonetheless, this average fails to precisely encapsulate the distinct characteristics of each region, where notable variations persist in travel distance, ranging from 88 km in the South to 448 km in the North. CONCLUSION: The influence of mobility and travel distance on access to BC care is multifaceted and should consider the complex interplay of geographic barriers, sociodemographic factors, health system issues, and policy-related challenges. Further research is needed to comprehensively understand the variables impacting access to health services, particularly in LATAM countries, where the challenges women face during treatment remain understudied.

Challenging diagnosis of Plasmodium ovale malaria in a Colombian traveler: the importance of including P. ovale wallikeri in molecular screening.

This study reports a challenging diagnosis of Plasmodium ovale malaria in a Colombian citizen returning from Cameroon. Initial microscopy screenings conducted at two private hospitals yielded conflicting results, with the first showing negative smears and the second diagnosing P. vivax. Subsequent microscopy examinations at two government laboratories identified P. ovale, although the routine species-specific PCR strategy was negative. PCR confirmation was finally obtained when P. ovale wallikeri primers were used. Although P. ovale is not frequently found in Colombia, there is a clear need to include both P. ovale curtisi and P. ovale wallikeri in the molecular diagnostic strategy. Such need stems primarily from their extended latency period, which affects travelers, the increasing number of African migrants, and the importance of accurately mapping the distribution of Plasmodium species in Colombia.

Impact of a teaching hospital-based multidisciplinary telemedicine programme in Southwestern Colombia: a cross-sectional resource analysis.

BACKGROUND: Telemedicine, a method of healthcare service delivery bridging geographic distances between patients and providers, has gained prominence. This modality is particularly advantageous for outpatient consultations, addressing inherent barriers of travel time and cost. OBJECTIVE: We aim to describe economical outcomes towards the implementation of a multidisciplinary telemedicine service in a high-complexity hospital in Latin America, from the perspective of patients. DESIGN: A cross-sectional study was conducted, analysing the institutional data obtained over a period of 9 months, between April 2020 and December 2020. SETTING: A high-complexity teaching hospital located in Cali, Colombia. PARTICIPANTS: Individuals who received care via telemedicine. The population was categorised into three groups based on their place of residence: Cali, Valle del Cauca excluding Cali and Outside of Valle del Cauca. OUTCOME MEASURES: Travel distance, time, fuel and public round-trip cost savings, and potential loss of productivity were estimated from the patient's perspective. RESULTS: A total of 62 258 teleconsultations were analysed. Telemedicine led to a total distance savings of 4 514 903 km, and 132 886 hours. The estimated cost savings were US$680 822 for private transportation and US$1 087 821 for public transportation. Patients in the Outside of Valle del Cauca group experienced an estimated average time savings of 21.2 hours, translating to an average fuel savings of US$149.02 or an average savings of US$156.62 in public transportation costs. Areas with exclusive air access achieved a mean cost savings of US$362.9 per teleconsultation, specifically related to transportation costs. CONCLUSION: Telemedicine emerges as a powerful tool for achieving substantial travel savings for patients, especially in regions confronting geographical and socioeconomic obstacles. These findings underscore the potential of telemedicine to bridge healthcare accessibility gaps in low-income and middle-income countries, calling for further investment and expansion of telemedicine services in such areas.

[Regional inequalities in access to hospital birth in the state of Rio de Janeiro, Brazil: travel networks, distance, and time (2010-2019)]. / Desigualdades regionais no acesso ao parto hospitalar no Estado do Rio de Janeiro, Brasil: redes de deslocamento, distância e tempo (2010-2019).

Difficult access to birth care services is associated with infant and neonatal mortality and maternal morbidity and mortality. In this study, data from the Brazilian Unified National Health System (SUS) were used to map the evolution of geographic accessibility to hospital birth of usual risk in the state of Rio de Janeiro, Brazil, corresponding to 418,243 admissions in 2010-2011 and 2018-2019. Travel flows, distances traveled, and intermunicipal travel time between the pregnant women's municipality and hospital location were estimated. An increase from 15.9% to 21.5% was observed in the number of pregnant women who needed to travel. The distance traveled increased from 24.6 to 26km, and the travel time from 76.4 to 96.1 minutes, with high variation between Health Regions (HR). Pregnant women living in HR Central-South traveled more frequently (37.4-48.9%), and those living in the HRs Baía da Ilha Grande and Northwest traveled the largest distances (90.9-132.1km) and took more time to get to the hospital in 2018-2019 (96-137 minutes). The identification of municipalities that received pregnant women from many other municipalities and municipalities that treated a higher number of pregnant women (hubs and attraction poles, respectively) reflected the unavailability and disparities in access to services. Regional inequalities and reduced accessibility highlight the need to adapt supply to demand and review the distribution of birth care services in the state of Rio de Janeiro. This study contributes to research and planning on access to maternal and child health services and can be used as a reference study for other states in the country.

A dificuldade de acesso aos serviços de atenção ao parto está associada à mortalidade infantil e neonatal e à morbimortalidade materna. Neste estudo, dados do Sistema Único de Saúde (SUS) foram utilizados para mapear a evolução da acessibilidade geográfica ao parto hospitalar de risco habitual no Estado do Rio de Janeiro, Brasil, correspondentes a 418.243 internações nos biênios 2010-2011 e 2018-2019. Foram estimados os fluxos de deslocamento, as distâncias percorridas e o tempo de deslocamento intermunicipal entre o município de residência e de internação das gestantes. Houve um crescimento de 15,9% para 21,5% na proporção de gestantes que precisaram se deslocar. A distância percorrida aumentou de 24,6 para 26km, e o tempo de deslocamento de 76,4 para 96,1 minutos, com grande variação entre as Regiões de Saúde (RS). As gestantes residentes na RS Centro Sul se deslocaram mais frequentemente (37,4-48,9%), e as residentes nas RS Baía da Ilha Grande e Noroeste percorreram as maiores distâncias (90,9-132,1km) e levaram mais tempo para chegar ao hospital no último biênio (96-137 minutos). A identificação dos municípios que receberam gestantes de muitos outros municípios e daqueles que atenderam maior volume de gestantes (núcleos e polos de atração, respectivamente) refletiu a indisponibilidade e as disparidades no acesso aos serviços. As desigualdades regionais e a redução da acessibilidade alertam para a necessidade de adequar a oferta à demanda e de revisar a distribuição dos serviços de atenção ao parto no Rio de Janeiro. O estudo contribui para as pesquisas e o planejamento sobre o acesso a serviços de saúde materno-infantil, além de servir como referência para outros estados do país.

Cutaneous myiasis caused by Dermatobia hominis (Diptera: Oestridae) in a Polish traveller to South America - a case report.

Myiasis, an infestation caused by dipteran larvae, commonly known as maggots, is one of the most common parasitic skin disorders in the tropical regions. Authors report a case of cutaneous myiasis caused by Dermatobia hominis (Diptera: Oestridae) in a Polish traveller returning from a self-organized trip to South America. Species biology, prophylaxis, and medical implications of this tropical parasitosis are discussed.

Safety of helicopter transport in patients with acute coronary syndrome.

BACKGROUND: ST-elevation myocardial infarction (STEMI) systems of care have reduced inter-hospital transfer times and facilitated timely reperfusion goals. Helicopters may be an option when land transportation is not feasible; however, the safety of air transport in patients with acute coronary syndrome (ACS) is a factor to consider. OBJETIVES: The aim of this study was to evaluate the safety of helicopter transport for patients with ACS. METHODS: Prospective, observational, and descriptive study including patients diagnosed with ACS within the STEMI network of a metropolitan city transferred by helicopter to a large cardiovascular center to undergo percutaneous coronary intervention. The primary outcome of the study was the incidence of air-travel-related complications defined as IV dislodgement, hypoxia, arrhythmia, angina, anxiety, bleeding, and hypothermia. Secondary outcomes included the individual components of the primary outcome. RESULTS: A total of 106 patients were included in the study; the mean age was 54 years and 84.9% were male. The most frequent diagnosis was STEMI after successful fibrinolysis (51.8%), followed by STEMI with failed fibrinolysis (23.7%) and non-reperfused STEMI (9.4%). Five patients (4.7%) developed at least one complication: IV dislodgement (1.8%) and hypoxemia (1.8%) in two patients and an episode of angina during flight (0.9%). A flight altitude of > 10,000 ft was not associated with complications. CONCLUSIONS: The results of this study suggest that helicopter transportation is safe in patients undergoing acute coronary syndrome, despite the altitude of a metropolitan area.

ANTECEDENTES: Los sistemas de atención de IAMCEST han reducido los tiempos de transferencia interhospitalaria y han facilitado las metas de reperfusión oportuna. Los helicópteros pueden ser una opción cuando el transporte terrestre no es factible; sin embargo, la seguridad del transporte aéreo en pacientes con síndrome coronario agudo (SICA) es un factor a considerar. OBJETIVOS: Evaluar la seguridad del transporte en helicóptero para pacientes con SICA. MÉTODOS: Estudio prospectivo, observacional, descriptivo. Se incluyeron pacientes con diagnóstico de SICA dentro de la red IAMCEST en metrópolis extensa, trasladados en helicóptero a un centro cardiovascular. El resultado primario del estudio fue la incidencia de complicaciones relacionadas con los viajes aéreos definidas cómo desalojo de catéter intravenoso, hipoxia, arritmia, angina, ansiedad, sangrado e hipotermia. RESULTADOS: Total de 106 pacientes; la edad media fue de 54 años y 84,9% eran hombres. La altitud media de vuelo fue de 10,100 pies y la distancia media de vuelo fue de 50,0 km. El diagnóstico más frecuente fue IAMCEST tras fibrinolisis exitosa (51,8%), seguido de IAMCEST con fibrinolisis fallida (23,7%). Cinco pacientes (4,7%) desarrollaron una complicación: desalojo IV (1,8%) e hipoxemia (1,8%) en dos pacientes y un episodio de angina durante el vuelo (0,9%). Una altitud de vuelo mayor de 10,000 pies no se asoció a complicaciones. CONCLUSIONES: Los resultados de este estudio sugieren que el transporte en helicóptero es seguro en pacientes con SICA, incluso en altitudes > 10,000 pies.

Persistence of dengue serotype 2 viral RNA in blood cells of a returned traveler with dengue fever.

Dengue virus (DENV) is one of the most significant vector-borne pathogens worldwide. In this report, we describe clinical features and laboratory detection of dengue in a 45-year-old traveler to Nicaragua on return home to the United States in 2019. Clinical presentation was mild, with rash, headache, and fatigue, with only low-grade transient fever. Infection dynamics were documented by serology and PCR of serially collected body fluids. DENV serotype 2 was detected in whole blood 1 day after symptoms emerged, with viral RNA isolated to the red cell fraction, and remained detectable through day 89. DENV-2 RNA was detected in serum only on day 4, and IgM was undetectable on day 4 but evident by day 13. Viral RNA was also detected in urine. This report of DENV-2 RNA persistence in blood cells but only transient appearance in serum, supports the potential diagnostic value of whole blood over serum for PCR and opportunity of an expanded testing window. Informed testing approaches can improve diagnostic accuracy and inform strategies that preserve individual and public health.

Intestinal protozoa in returning travellers: a GeoSentinel analysis from 2007 to 2019.

BACKGROUND: Prolonged diarrhoea is common amongst returning travellers and is often caused by intestinal protozoa. However, the epidemiology of travel-associated illness caused by protozoal pathogens is not well described. METHODS: We analysed records of returning international travellers with illness caused by Giardia duodenalis, Cryptosporidium spp., Cyclospora cayetanensis or Cystoisospora belli, reported to the GeoSentinel Network during January 2007-December 2019. We excluded records of travellers migrating, with an unascertainable exposure country, or from GeoSentinel sites that were not located in high-income countries. RESULTS: There were 2517 cases, 82.3% giardiasis (n = 2072), 11.4% cryptosporidiosis (n = 287), 6.0% cyclosporiasis (n = 150) and 0.3% cystoisosporiasis (n = 8). Overall, most travellers were tourists (64.4%) on long trips (median durations: 18-30 days). Cryptosporidiosis more frequently affected people < 18 years (13.9%) and cyclosporiasis affected people ≥ 40 years (59.4%). Giardiasis was most frequently acquired in South Central Asia (45.8%) and sub-Saharan Africa (22.6%), cryptosporidiosis in sub-Saharan Africa (24.7%) and South-Central Asia (19.5%), cyclosporiasis in South East Asia (31.3%) and Central America (27.3%), and cystoisosporiasis in sub-Saharan Africa (62.5%). Cyclosporiasis cases were reported from countries of uncertain endemicity (e.g. Cambodia) or in countries with no previous evidence of this parasite (e.g. French Guiana). The time from symptom onset to presentation at a GeoSentinel site was the longest amongst travellers with giardiasis (median: 30 days). Over 14% of travellers with cryptosporidiosis were hospitalized. CONCLUSIONS: This analysis provides new insights into the epidemiology and clinical significance of four intestinal protozoa that can cause morbidity in international travellers. These data might help optimize pretravel advice and post-travel management of patients with travel-associated prolonged gastrointestinal illnesses. This analysis reinforces the importance of international travel-related surveillance to identify sentinel cases and areas where protozoal infections might be undetected or underreported.

[Pretravel medical consultation]. / Reisemedizinische Beratung.

Many patients seek pretravel advice during routine consultations in a general practice so that basic knowledge of travel medicine is warranted. Using the example of trips to Bali, Peru and Tanzania, the most relevant topics of a pretravel consultation for these popular destinations are depicted. These include vaccinations, malaria prevention and recommendations on exposure prophylaxis for insect bites. Furthermore, special risk situations, such as travel to high altitudes or freshwater contact are discussed. In special cases, the advice of an expert in travel medicine is needed.

Detecting Residual Chronic Salmonella Typhi Carriers on the Road to Typhoid Elimination in Santiago, Chile, 2017-2019.

BACKGROUND: In Santiago, Chile, where typhoid had been hyperendemic (1977-1991), we investigated whether residual chronic carriers could be detected among household contacts of non-travel-related typhoid cases occurring during 2017-2019. METHODS: Culture-confirmed cases were classified as autochthonous (domestically acquired) versus travel/immigration related. Household contacts of cases had stool cultures and serum Vi antibody measurements to detect chronic Salmonella Typhi carriers. Whole genome sequences of acute cases and their epidemiologically linked chronic carrier isolates were compared. RESULTS: Five of 16 autochthonous typhoid cases (31.3%) were linked to 4 chronic carriers in case households; 2 cases (onsets 23 months apart) were linked to the same carrier. Carriers were women aged 69-79 years with gallbladder dysfunction and Typhi fecal excretion; 3 had highly elevated serum anti-Vi titers. Genomic analyses revealed close identity (≤11 core genome single-nucleotide polymorphism [SNP] differences) between case and epidemiologically linked carrier isolates; all were genotypes prevalent in 1980s Santiago. A cluster of 4 additional autochthonous cases unlinked to a carrier was identified based on genomic identity (0-1 SNPs). Travel/immigration isolate genotypes were typical for the countries of travel/immigration. CONCLUSIONS: Although autochthonous typhoid cases in Santiago are currently rare, 5 of 16 such cases (31.3%) were linked to elderly chronic carriers identified among household contacts of cases.

Causes of death among international travellers in Peru, 2017 to 2021.

BACKGROUND: The wellbeing and safety of international tourists is a paramount concern for governments and stakeholders. Mortality among travellers and the causes of death serve as a significant metric of destination safety. We describe the epidemiology and causes of death among international travellers in Peru. METHODS: Data retrieved from the Peruvian government's deaths certificates registry included all non-residents who died between January 2017 and December 2021. We analysed the national incidence and causes of death among international travellers in Peru. Causes of death were classified into non-communicable diseases (NCD), communicable diseases and injuries. We classified fatalities according to the existence of preventive measures that could be provided during the travel medicine consultation to decrease the risk. RESULTS: We obtained records from 1514 deaths among international travellers (973 males, 64%). The incidence increased from 0.2 deaths per 10 000 travellers in 2017 to 9.9 in 2021. NCDs were the most common causes of death (n = 560, 37%), followed by communicable diseases (n = 487, 32%), and injuries (n = 321, 21%). Causes of death were unknown in 9.7% of the records. The leading causes of death in these categories were cancer, cardiovascular disease, COVID-19 and trauma. We found similar sex distribution of NCDs in travellers aged >50 years and higher rates of communicable diseases among males across all ages. Injury-associated deaths were significantly higher among males aged 18-29 years (P < 0.001) compared with other sex-age groups. We estimated that for 57.7% of deaths risk could have been decreased through pre-travel advice. CONCLUSION: Rates of deaths among travellers to Peru increased over time. Most deaths were due to NCDs, followed by communicable diseases and injuries. Pre-travel medical optimization and effective advice focused on age-sex and destination specific risks could reduce risk among travellers. Increased awareness among travel medicine practitioners and improvement of emergency medical response systems in Peru could decrease mortality.

Bio-inspired artificial somatic index for reflecting the travel experience of passenger agents under a flexible transportation scenario.

This work analyzes the implementation of an artificial mechanism inspired by a biological somatic marker that ables a passenger agent to both, react to changes in the service, as well as keep said reactions as a memory for future decisions. An artificial mental model was designed, and the passenger agent was implemented as an autonomous decision-making system, where both, the choice of the transport operator and the evaluation of the received service were fully delegated to the system. The evaluation of the service experience is not only based on rational aspects (such as the cost of the trip) but also on subjective aspects related to the satisfaction level derived from the passenger's experience. The experimental scenario considered 10,000 trip requests simulated within an artificial map that emulates characteristics that are usually present in a city, such as vehicular congestion, the unsafety of certain streets, or the benefits of an area with tourist interest. The results show that the option to travel under a transport operator with a touristic profile is a trend. Unlike current cases in the industry, this research work explores the scenario where the passenger can have as a client a trip profile with memory, differentiated from other clients, and can receive more than one trip proposal for the same trip request, according to the different conditions that the passenger is looking for.

Honores a Sir Ernest Shackleton en Sanidad Militar / Honors to Sir Ernest Shackleton in Military Health / Honras a Sir Ernest Shackleton em Saúde Militar

Ernest Shackleton ha sido en la historia, un personaje que dejó huella como ejemplo de resiliencia y liderazgo. En 1914 realizó como jefe de expedición su segundo viaje antártico, frustrado por el hundimiento de su buque insignia. La operación de rescate del grueso de la tripulación varada en el continente más meridional lo llevó a recalar en Montevideo. Desde este puerto partió el buque Instituto de Pesca N°1, con tripulación de Uruguay y Shackleton incluido, no logrando completar el salvamento. De esta acción nació el aprecio hacia la persona del explorador por parte del gobierno de la República. En su postrer travesía, ya fallecido llegó a las Islas Georgia del Sur y a su cuerpo se le realizó un proceso de conservación para ser traído a nuestro país y continuar viaje al puerto de origen en Inglaterra. Es en esa circunstancia que el gobierno del doctor Baltasar Brum solicitó a la Comisión Permanente del Parlamento, se le rindieran honores fúnebres de Ministro de Estado. El embalsamado del cuerpo fue realizado el 30 de enero de 1922, por parte de personal médico y técnico del Hospital Militar, así como los honores que le rindieron por el Servicio de Sanidad del Ejército y la Armada.

Ernest Shackleton has been in history, a character who left his mark as an example of resilience and leadership. In 1914, as expedition leader, he made his second Antarctic voyage, frustrated by the sinking of his flagship. The operation to rescue the bulk of the crew stranded on the southernmost continent led him to Montevideo. The Instituto de Pesca N°1, with Uruguayan crew and Shackleton included, departed from this port, but was unable to complete the rescue. From this action was born the appreciation of the explorer by the government of the Republic. In his last voyage, when he died, he reached the South Georgia Islands and his body underwent a preservation process to be brought to our country and continue his voyage to the port of origin in England. It is in this circumstance that the government of Dr. Baltasar Brum requested the Permanent Commission of the Parliament to pay him the funeral honors of a Minister of State. The embalming of the body was carried out on January 30, 1922, by medical and technical personnel of the Military Hospital, as well as the honors rendered by the Army and Navy Health Service.

Ernest Shackleton deixou sua marca na história como um exemplo de resiliência e liderança. Em 1914, ele fez sua segunda viagem à Antártica como líder da expedição, frustrado pelo naufrágio de seu navio principal. A operação para resgatar a maior parte da tripulação encalhada no continente mais ao sul o levou a Montevidéu. O Instituto de Pesca N°1, com tripulação do Uruguai e Shackleton incluído, partiu desse porto, mas não conseguiu concluir o resgate. Essa ação deu origem ao reconhecimento do explorador pelo governo da República. Em sua última viagem, quando morreu, chegou às Ilhas Geórgia do Sul e seu corpo foi preservado para que pudesse ser trazido ao nosso país e continuar sua viagem até o porto de origem na Inglaterra. Foi nessa circunstância que o governo do Dr. Baltasar Brum solicitou ao Comitê Permanente do Parlamento que lhe prestasse as honras fúnebres de um Ministro de Estado. O embalsamamento do corpo foi realizado em 30 de janeiro de 1922, pela equipe médica e técnica do Hospital Militar, bem como as honras prestadas a ele pelo Serviço de Saúde do Exército e da Marinha.

Impact of travel burden on the treatment of stage I and II breast cancer: A National Cancer Database analysis.

BACKGROUND: Although historic studies of state registries have demonstrated decreased radiation therapy use for patients with breast cancer living further away from radiation facilities, the association between travel distance and breast cancer treatment in a modern national cohort remains unknown. METHODS: Female patients with estrogen receptor/progesterone receptor positive and human epidermal growth factor receptor 2 negative pathologic stages I to II breast cancer were identified from the National Cancer Database (2018-2020) and dichotomized by distance ≤20 miles or >20 miles (75th percentile) from the treatment facility. The association between travel distance and type of surgery and treatment administered was analyzed by univariate and multivariate logistic regression and after 1:1 propensity matching. RESULTS: Of the 293,318 patients identified for inclusion, the median age was 63 years, and most patients (n = 190,567, 65%) lived ≤20 miles of the treatment facility. Patients with a travel burden >20 miles were more likely to receive a mastectomy (≤20 miles 30.4% vs >20 miles 34.0%, P < .001; odds ratio 1.14, P = .016), and less likely to receive radiation (≤20 miles 63.3% vs >20% miles 60.1%, P < .001; odds ratio 0.81, P < .001). These findings persisted after propensity score matching (n = 33,544 per cohort), with patients living further being more likely to undergo a mastectomy (≤20 miles 30.3% vs >20 miles 35.3%, P < .001) and less likely to receive radiation (≤ 20 miles 65.4% vs. >20 miles 58.5%, P < .001). CONCLUSION: Patients with hormone receptor-positive stage I to II breast cancer with a larger travel burden are more likely to receive a mastectomy and less likely to undergo radiation therapy to treat their disease.
