RESUMO
Introducción: Personas con cáncer colorrectal (CCR) pueden presentar efectos adversos, perjudicando la calidad de vida relacionada a la salud (CVRS). Objetivo: Validar el módulo QLQ CR29 para evaluación de la CVRS, en Chile. Materiales y método: Estudio transversal que incluyó 170 personas con CCR. Se analizaron la consistencia interna y validez de constructo del instrumento con test de hipótesis. Resultados: 117 personas (68,8%) fueron evaluadas antes de la cirugía y 53 (31,2%) después de la cirugía. La consistencia interna del QLQ CR29 fue α = 0,838. Fueron comprobadas las hipótesis planteadas: Los pacientes evaluados antes de la cirugía se quejaron más de "sangre/mucosidad en las heces", "dolor abdominal", "pérdida de cabello" e "hinchazón abdominal", mientras que los pacientes evaluados después presentaron más "incontinencia fecal" (p < 0,05). Antes de la cirugía, los pacientes con cáncer de recto CCR presentaron mayores valores de "frecuencia urinaria", "frecuencia de deposiciones", "dolor en las nalgas", "problemas con el gusto" y "vergüenza"; mientras que aquellos con cáncer de colon que se quejaban más de "sangre/mucosidad en las heces" (p < 0,05). Después de la cirugía, los pacientes con cáncer de recto tenían mayor "frecuencia de deposiciones", "eliminación de gases" y "vergüenza" (p = 0,004) en comparación con los con cáncer de colon (p < 0,05). Los pacientes ostomizados presentaron más "incontinencia fecal" y "vergüenza" (p < 0,001). Fueron observadas correlaciones positivas y negativas bajas entre la mayoría de las dimensiones del QLQ CR29 con las dimensiones del QLQ C30. Conclusión: La versión chilena del módulo QLQ CR29 es adecuada para evaluar la CVRS en personas con CCR.
Introduction: People with colorectal cancer (CRC) can present adverse effects, impairing the quality of life related to health (HRQoL). Objective: To validate the QLQ-CR29 module for the assessment of HRQoL, in Chile. Materials and method: Cross-sectional study that included 170 people with CRC. The internal consistency and construct validity (hypothesis tests) were analyzed. Results: 117 patients (68.8%) were evaluated before surgery and 53 (31.2%) after tumor resection. The internal consistency of the QLQCR29 was α = 0.838. The proposed hypotheses were confirmed: The patients evaluated before surgery complained more of "blood/mucus in the stool", "abdominal pain", "hair loss" and "abdominal swelling", while the patients evaluated after presented more "fecal incontinence" (p < 0.05). Before surgery, patients with rectal cancer presented higher values of "urinary frequency", "frequency of stools", "pain in the buttocks", "taste problems" and "embarrassment"; while those with colon cancer complained more of "blood/mucus in stool" (p < 0.05). After surgery, patients with CCR had higher "stool frequency", "flatus" and "embarrassment" (p = 0.004) compared with those with colon cancer (p < 0.05). Ostomized patients presented more "fecal incontinence" and "embarrassment" (p < 0.001). Low significant correlations were observed between most of the dimensions of the QLQ CR29 with the dimensions of the QLQ C30. Conclusion: The Chilean version of the QLQ CR29 module is adequate to assess HRQoL in people with CRC.
RESUMO
AIM: To assess the value of a prehabilitation program adapted to the current COVID-19 pandemic using a teleprehabilitation modality in a public Latin American hospital. METHODS: The medical records of candidates for elective colorectal cancer surgery (CRC) and who completed a teleprehabiltation program were analyzed. Sociodemographic, clinical, and functional variables were analyzed, such as cardiorespiratory capacity with the sit-to-stand test (STST), independence in activities of daily living with the Barthel index, balance with the five-times STST (FSTST) and fatigue with Brief Inventory Fatigue (BFI). The feasibility of the program was analyzed in terms of recruitment, retention, user satisfaction, and reporting of adverse events. RESULTS: Of 107 people recruited, 57 completed the program (54%, 68.78 ± 12.36 years). There was a significant difference in the BFI, FSTST, and STS 1-min scores after the intervention (p < .01), with an effect size (Cliff's delta) that varied between -.13 and .21. There were no differences in the Barthel index score. In relation to the viability of the program, 99% of patients referred for surgery could be recruited into the program, with 53% retention. Regarding user satisfaction with the program, seven items (77.7%) were rated as "very satisfied," and two items (22.3%) as "satisfied." No adverse events were recorded. CONCLUSION: The structured prehabilitation program adapted to teleprehabilitation for CRC candidates for surgery was effective in optimizing functional results prior to surgery and was feasible to implement in a public hospital with limited resources during the COVID-19 pandemic.

The exploitation of both conventional and unconventional hydrocarbons may lead to still not well-known environmental consequences such as ground deformation and induced/triggered seismicity. Identifying and characterizing these effects is fundamental for prevention or mitigation purposes, especially when they impact populated areas. Two case studies of such effects on hydrocarbon-producing basins in Argentina, the Neuquén and the Golfo de San Jorge, are presented in this work. The intense hydrocarbon production activities in recent years and their potential link with the occurrence of two earthquakes of magnitude 4.9 and 5 near the operating well fields is assessed. A joint analysis of satellite radar interferometry and records of fluid injection and extraction demonstrate that, between 2017 and 2020, vertical ground displacements occurred in both study areas over active well fields that might indicate a correlation to hydrocarbon production activities. Coseismic deformation models of the two earthquakes constrain source depths to less than 2 km. The absence of seismicity before the beginning of the hydrocarbon activities in both areas, and the occurrence of the two largest and shallow earthquakes in the vicinity of the active well fields just after intensive production periods, points towards the potential association between both phenomena.

BACKGROUND: Patients with COVID-19 can present functional status and disability alterations in the medium- and long-term. On the international level, a multicentered study is being carried out to validate the Post-COVID-19 Functional Status scale for different nations, thus allowing visualizing the needs for a multidisciplinary approach and planning intervention plans. The objective of this study was to perform a linguistic validation and cross-cultural adaptation of the Post-COVID-19 Functional Status scale for people infected with COVID-19 for the Chilean population. METHODS: A cross-sectional study of scale validation was carried out. The study was performed in two phases: (1) forward-translation, reverse-translation and (2) apparent cross-validity adaptation. For the apparent validity analysis, 29 individuals who had been hospitalized in Hospital del Salvador with a COVID-19 infection diagnosis and at the time of the interview were in their homes participated. RESULTS: In phase 1 forward-translation, an item required semantical changes. The reverse-translation versions were similar, and the most relevant doubts were resolved in a consensus meeting. In phase 2, the pilot study confirmed adequate understanding and scale applicability. CONCLUSIONS: Using a systematic and rigorous methodology allowed obtaining a Spanish version of the Post-COVID-19 Functional Status scale for Chile, which is conceptually and linguistically equivalent to the original instrument and adequate to assess the functional status of people infected with COVID-19.

Hepatitis A, a vaccine preventable disease, is now of transitional or intermediate endemicity in Argentina, as the epidemiologic pattern of the disease has shifted with improvements in living conditions in some parts of the country. Increase in the susceptibility of older children and adults has led to increasing disease incidence. Molecular epidemiology has played an important role in the understanding of HAV infection by identifying modes of spreading and by permitting the monitoring of changes in circulating virus brought about by prevention programs. South American isolates characterized are limited. Eighty-two sporadic and outbreak isolates from Argentina were sequenced in the VP1/2A region of HAV genome over a 9-year period. All the isolates belonged to subgenotype IA. All our sequences grouped into two big clusters. Apparently, at least two lineages have been co-circulating in the same place at the same time. Despite great genetic variability, few point amino acid changes could be deduced. Four sequences showed an Arg --> Lys substitution at 1-297 which characterized the genotype IB at the amino acid level. Many isolates carried a conservative amino acid substitution Leu --> Ile at position 42 of the 2A domain, previously described as a possible fingerprint of HAV sequences in Brazil. The other rare changes have been found before, except for a 1-277 Asn --> Ser substitution displayed in two isolates that has not been previously reported. Argentina recently implemented universal vaccination in 1-year-old children. Molecular tools would be useful in an active surveillance program.
