Use of a 3D virtual app and academic performance in the study of the anatomy of the musculoskeletal system among Peruvian medical students
Objective: To evaluate the association between the use of a 3D virtual App and academic performance among Peruvian medical students. In addition, factors associated with academic performance were also assessed.
Methods: We conducted an analytical cross-sectional study in students enrolled in the Musculoskeletal System course during the first semester of 2019. Students filled out a data collection form and the "Self-directed learning readiness scale" (SDLRS) questionnaire adapted by Fisher, King, and Tangle. Linear regression models were carried out to assess the association between the appropriate use of the application and academic performance. Additionally, the factors associated with academic performance were evaluated using nested models, and beta coefficients were calculated by manual forward selection.
Results: A total of 187 medical students were included. The 61% were female and the median age was 21 [20-22] years. The average grade was 13.5 +/- 2 and 21% reported an adequate use of a 3D App. No association was found between the use of the 3D App and academic performance in the adjusted model (a beta = 0.17; 95% CI: -0.45 to 0.80). We found that age (a beta = -0.22; 95% CI: -0.39 to -0.06), performing extracurricular activities (a beta = 0.75, 95% CI: 0.25 to 1.24) and having failed an anatomy/physiology course before (a beta = -2.11 to 95% CI: -2.9 to -1.8) were factors associated with academic performance.
Conclusion: The adequate use of a 3D application to study the anatomy of the musculoskeletal system was not significantly associated with better academic performance.Revisión por pare
Observation of confined current ribbon in JET plasmas
we report the identification of a localised current structure inside the JET
plasma. It is a field aligned closed helical ribbon, carrying current in the
same direction as the background current profile (co-current), rotating
toroidally with the ion velocity (co-rotating). It appears to be located at a
flat spot in the plasma pressure profile, at the top of the pedestal. The
structure appears spontaneously in low density, high rotation plasmas, and can
last up to 1.4 s, a time comparable to a local resistive time. It considerably
delays the appearance of the first ELM.Comment: 10 pages, 6 figure
Microbiological profile of infections in the Intensive Care Units of Colombia (EPISEPSIS Colombia)
Introducción y objetivo
En Colombia faltan datos fiables sobre el comportamiento de la sepsis. Se pretende determinar la prevalencia de los microorganismos en las principales infecciones tratadas en las unidades de cuidados intensivos (UCI) de nuestro país.
Métodos
Este es un subestudio de una cohorte prospectiva recolectada en 10 hospitales durante 6 meses. Los criterios de inclusión eran hospitalización en UCI y confirmación de una infección según las definiciones del CDC, considerando tres grupos (comunidad, hospital, UCI) según el sitio de adquisición de la infección.
Resultados
Se incluyó en el análisis a 826 pacientes; el 51% contrajeron procesos infecciosos extrahospitalarios; el 5,33%, en el hospital y el 43,7%, en UCI. Los diagnósticos más frecuentes fueron neumonía (29,54%), infección intraabdominal (18,16%) e infección del tracto urinario (11,62%). El microorganismo más frecuente en las infecciones extrahospitalarias fue Escherichia coli —pulmón (16,4%), peritoneo (57,7%), orina (55,5%) y sangre (22,4%)—. En las adquiridas en UCI predomina también E. coli —peritoneo (29,3%) y orina (52,9%)—, excepto en pulmón y sangre, en los que fueron Staphylococcus aureus (32,4%) y Klebsiella pneumoniae (15,7%) los más prevalentes. Se tomaron cultivos a 655 pacientes, de los que el 40% recibió antibióticos antes de la toma, sin que esto afectara al porcentaje de positividad (p=0,583).
Conclusiones
La neumonía fue la infección más frecuente independientemente del sitio de adquisición. E. coli fue el patógeno más prevalente, excepto en las infecciones pulmonares adquiridas en UCI, donde lo fue S. aureus.Q2Artículo original75-83Background and objective:Valid and reliable data regarding sepsis is lacking in Colombia. Ouraim was to determine the prevalence of the microorganisms in the main infections treated inIntensive Care Units (ICUs) in our country.Methods:This is a sub-study of a prospective cohort with 10 general hospitals in Colombiaduring a 6-month period. The inclusion criteria were hospitalization in ICU and confirmation ofinfection according to the CDC definitions. Patients were classified into three groups, that is,community, hospital and intensive care, according to the site where the infection was acquired.Results:A total of 826 patients were included in this analysis. Of these, 51% developed infec-tions in the community, 5.33% in the hospital and 43.7% in intensive care unit. Overall, themost common diagnoses were pneumonia (29.54%), intra-abdominal infection (18.16%) and uri-nary tract infection (11.62%). The most frequent germ in community-acquired infections wasE. coli—–lung (16. 4%), peritoneum (57.7%), urine (55.5%), blood (22.4%)—–.E. coli—–peritoneum(29.3%), urine (52.9%)—– also predominated in the ICU-acquired infections, except for lung andblood in whichStaphylococcus aureus(32.4%) andKlebsiella pneumoniae(15.7%) were the mostprevalent. Cultures were requested from 655 patients, 40% of them having received antibioticsbefore cultures were taken, although this did not affected the percentages of positive cultures(P= 0.583).Conclusions:Pneumonia was the main cause of infection regardless of the site of acquisition.E. coliwas the most prevalent germ, except in the pulmonary infections acquired in UCI inwhichS. aureuswas the most prevalent
Autoimmune/inflammatory syndrome induced by adjuvants: a review
The autoimmune/inflammatory syndrome induced by adjuvants (ASIA) includes several autoimmune conditions and phenomena that occur after exposure to substances with adjuvant activity. The spectrum of the disease is heterogeneous with respect to the clinical presentation as well as the severity of the clinical manifestations. Different substances and medical devices with adjuvant activity are currently known, such as vaccines, oils, silicones, mineral salts, lipopolysaccharides, peptidoglycans, among others. These adjuvants are immunological molecules that function through potentiation of antigen-specific immune responses. Thus, the etiopathogenesis of ASIA syndrome involves a multifactorial interaction between environmental factors and genetic predisposition, and secondary activation of the adaptive and innate arms of the immune system through various mechanisms. Although in some reported cases the ASIA syndrome improves considerably when removing the implants, there are no conclusive results for the clinical benefit of removing the implants, so it is necessary to carry out further basic, clinical and surgical investigations in order to determine the best therapeutic decision

Clinical course of sepsis, severe sepsis, and septic shock in a cohort of infected patients from ten Colombian hospitals
ABSTARCT: Sepsis has several clinical stages, and mortality rates are different for each stage. Our goal was to
establish the evolution and the determinants of the progression of clinical stages, from infection to septic shock,
over the first week, as well as their relationship to 7-day and 28-day mortality
