RESUMO

BACKGROUND: Vaccination is our main strategy to control SARS-CoV-2 infection. Given the decrease in quantitative SARS-CoV-2 spike 1-2 IgG antibody titers three months after the second BNT162b2 dose, healthcare workers received a third booster six months after completing the original protocol. This study aimed to analyze the quantitative SARS-CoV-2 spike 1-2 IgG antibody titers and the safety of the third dose. MATERIAL AND METHODS: A prospective longitudinal cohort study included healthcare workers who received a third booster six months after completing the BNT162b2 regimen. We assessed the quantitative SARS-CoV-2 spike 1-2 IgG antibody titers 21-28 days after the first and second dose, three months after the completed protocol, 1-7 days following the third dose, and 21-28 days after booster administration. RESULTS: The cohort comprised 168 participants aged 41(10) years old, 67% of whom were female. The third dose was associated with an increase in quantitative antibody titers, regardless of previous SARS-CoV-2 history. In cases with a negative SARS-CoV-2 history, the median (IQR) antibody titer values increased from 379 (645.4) to 2960 (2010) AU/ml, whereas in cases with a positive SARS-CoV-2 history, from 590 (1262) to 3090 (2080) AU/ml (p<0.001). The third dose caused a lower number of total (local and systemic) adverse events following immunization (AEFI) compared with the first two vaccines. However, in terms of specific symptoms such as fatigue, myalgia, arthralgia, fever, and adenopathy, the proportion was higher in comparison with the first and second doses (p<0.05). The most common AEFI after the third BNT162b2 vaccine was pain at the injection site (n = 82, 84.5%), followed by fatigue (n = 45, 46.4%) of mild severity (n = 36, 37.1%). CONCLUSION: The third dose applied six months after the original BNT162b2 regimen increased the quantitative SARS-CoV-2 spike 1-2 IgG antibody titers. The booster dose was well tolerated and caused no severe AEFI.

RESUMO

Background: Determine the behavior of the maxillofacial trauma of adults treated in 3 tertiary care centers in the central zone of Chile. Material and Methods: descriptive, cross-sectional, multicenter study, based on the prospective records of maxillofacial trauma cases attended between May 2016 and April 2017 by dental and maxillofacial clinical teams of Adult Emergency Units of hospitals Dr. Sótero del Río (metropolitan region), Carlos Van Buren and Dr. Gustavo Fricke (region V). Age, sex, date of occurrence, type of trauma according to ICD-10, etiology, legal medical prognosis and associated injuries were recorded, stratifying by sex and age. Chi square and unpaired Wilcoxon tests were used to compare by groups. Results: 2.485 cases and 3.285 injuries were investigated. The male: female ratio was 1.7: 1 with age under 30 predominant, followed by older adults. Variability was observed in the yearly, weekly and daily presentation The highest frequencies were in January and September, weekends and at night. The main etiologies were violence (42.3%), falls (13.1%) and road traffic crashes (12.9%) with differences by age and sex (p <0.05). 31,9% of the injuries occurred in hard tissue, being fractures in nasal bones predominant (S02.2). Conclusions: the profile of the maxillofacial trauma in Chile seems to be mixed by age, affecting young people and the elderly. The male sex predominates; the main cause, which varies by age group, is violence. Their surveillance is possible from hospital emergency records

RESUMO

We have developed a new methodology for examining and extracting patterns from brain electric activity by using data mining and machine learning techniques. Data was collected from experiments focused on the study of cognitive processes that might evoke different specific strategies in the resolution of math problems. A binary classification problem was constructed using correlations and phase synchronization between different electroencephalographic channels as characteristics and, as labels or classes, the math performances of individuals participating in specially designed experiments. The proposed methodology is based on using well-established procedures of feature selection, which were used to determine a suitable brain functional network size related to math problem solving strategies and also to discover the most relevant links in this network without including noisy connections or excluding significant connections.

RESUMO

At a think tank bringing together experts on fetal neuroimaging, obstetric infectious diseases, and public health, we discussed trends in all of these areas for Zika virus. There is a wide variety of imaging findings in affected fetuses, influenced by timing of infection and probably host factors. The resources for diagnosis and interventions also vary by location with the hardest hit areas often having the fewest resources. We identified potential areas for both research and clinical collaboration as the Zika virus epidemic continues to evolve.

RESUMO

There are many studies in the marketing and diffusion literature of the conditions in which social contagion affects adoption processes. Yet most of these studies assume that social interactions do not change over time, even though actors in social networks exhibit different likelihoods of being influenced across the diffusion period. Rooted in physics and epidemiology theories, this study proposes a Susceptible Infectious Susceptible (SIS) model to assess the role of social contagion in adoption processes, which takes changes in social dynamics over time into account. To study the adoption over a span of ten years, the authors used detailed data sets from a community of consumers and determined the importance of social contagion, as well as how the interplay of social and non-social influences from outside the community drives adoption processes. Although social contagion matters for diffusion, it is less relevant in shaping adoption when the study also includes social dynamics among members of the community. This finding is relevant for managers and entrepreneurs who trust in word-of-mouth marketing campaigns whose effect may be overestimated if marketers fail to acknowledge variations in social interactions.

RESUMO

We address the problem of long-term dynamics of tuberculosis (TB) and latent tuberculosis (LTB) in semiclosed communities. These communities are congregate settings with the potential for sustained daily contact for weeks, months, and even years between their members. Basic examples of these communities are prisons, but certain urban/rural communities, some schools, among others could possibly fit well into this definition. These communities present a sort of ideal conditions for TB spread. In order to describe key relevant dynamics of the disease in these communities, we consider a five compartments SEIR model with five possible routes toward TB infection: primary infection after a contact with infected and infectious individuals (fast TB), endogenous reactivation after a period of latency (slow TB), relapse by natural causes after a cure, exogenous reinfection of latently infected, and exogenous reinfection of recovered individuals. We discuss the possible existence of multiple endemic equilibrium states and the role that the two types of exogenous reinfections in the long-term dynamics of the disease could play.

RESUMO

BACKGROUND: Severe dysphagia or even aphagia can occur after esophagectomy secondary to necrosis of the ascended organ with severe stricture or complete separation of the stumps. Catastrophic esophageal or gastric disruption drives the decision to "disconnect" the esophagus in order to prevent severe septic complications. The operations employed to re-establish esophageal discontinuity are not standardized and reoperations for re-establishment of the upper digestive transit are a real challenge. METHODS: This is retrospective study collecting the authors experience during 17 years including 18 patients, 14 of them previously submitted to esophagectomy and four to esophagogastrectomy. They were operated on in order to re-establish the upper digestive tract. RESULTS: Redo esophago-gastro-anastomosis was possible in 12 patients, 10 through cervical approach and combined with sternotomy in four in order to perform the new anastomosis. In five patients a new esophago-colo anastomosis was performed. Free jejunal graft interposition was performed in one patient. Complications occurred in ten patients (55.5 %): anastomotic leaks in three, strictures in four, sternal condritis in two and cervical abscess in one. No mortality was observed. CONCLUSION: There are different surgical options for the treatment of this difficult and risky clinical situation which must be treated with tailored procedures according to the anatomic segment available to be used, choosing the most conservative procedure.

RESUMO

RACIONAL: Disfagia grave ou mesmo afagia pode ocorrer após esofagectomia secundária à necrose do órgão ascendido com estenose severa ou separação completa dos cotos. Ruptura catastrófica esofágica ou gástrica impulsiona a decisão de "desconectar" o esôfago, a fim de evitar graves complicações sépticas. As operações utilizadas para restabelecer a descontinuidade do esôfago não são padronizadas e reoperações para restabelecimento do trânsito digestivo superior são um verdadeiro desafio. MÉTODOS: Este é estudo retrospectivo da experiência dos autores durante 17 anos incluindo 18 pacientes, 14 previamente submetidos à esofagectomia e quatro esofagogastrectomia. Eles foram operados com o fim de restabelecer o trato digestivo superior. RESULTADOS: Refazer esofagogastro anastomose foi possível em 12 pacientes, 10 por meio da abordagem cervical e combinando esternotomia em quatro, a fim de realizar a nova anastomose. Em cinco pacientes esofagocolo anastomose foi novamente realizada. Interposição de enxerto livre de jejuno foi realizada em um paciente. As complicações ocorreram em 10 pacientes (55,5%): deiscência anastomótica em três, estenose em quatro, condrite esternal em dois e abscesso cervical em um. Não se observou mortalidade. CONCLUSÃO: Existem diferentes opções cirúrgicas para o tratamento desta situação clínica difícil e arriscada; deve ser tratada com procedimentos adaptados de acordo com o segmento anatômico disponível para ser usado, escolhendo o procedimento mais conservador.

RESUMO

The objective of this study was to evaluate sleeve gastrectomy with jejunal bypass (SGJB) as a surgical treatment for type 2 diabetes mellitus (T2DM) in patients with a body mass index (BMI) <35 kg/m(2). This is a prospective cohort study. Patients with T2DM and BMI <35 kg/m(2) who underwent SGJB between January 2009 and June 2011 at DIPRECA Hospital, in Santiago, and Hospital Base, Osorno, Chile were included. SGJB consists of creating a gastric tube, which preserves the pylorus, and performing a jejunoileal anastomosis 300 cm distal to the angle of Treitz. Excess weight loss (EWL) and complete or partial remission of T2DM were reported. Forty-nine patients met the inclusion criteria. The mean age was 49 years (36-62), and 53 % of patients were female. Mean preoperative BMI was 31.6 kg/m(2) (25-34.9 kg/m(2)). Operation time was 123 ± 14 min, with 94.7 % of operations performed laparoscopically. Mean postoperative hospital stay was 2 days. Mean postoperative follow-up was 12 months. Median EWL at 1, 3, 6, 12, and 18 months postoperatively was 31.9 %, 56.9 %, 76.1 %, 81.5 %, and 76.1 %, respectively. Complete T2DM remission was achieved in 81.6 % of patients (40/49) and partial remission in 18.4 % (9/49). Forty of 41 patients (97.6 %) on oral hypoglycemic agents achieved complete T2DM remission, and 100 % of insulin-dependent patients stopped using insulin but were still being treated for T2DM. One patient experienced postoperative gastrointestinal bleeding. There were no deaths. SGJB is an effective treatment for T2DM in patients with BMI <35 kg/m(2).

RESUMO

OBJECTIVE: The purpose of this study was to assess the diagnostic correlation between indirect MR arthrography, conventional MRI, and arthroscopy in acetabular labral and cartilage lesions of the hip. MATERIALS AND METHODS: Fourteen patients who underwent conventional and indirect MR arthrography with arthroscopic correlation were studied over the course of 18 months. MR studies were performed on a 1.5-T magnet. Sequences consisted of unilateral sagittal turbo spin-echo proton density fat-suppressed, axial turbo spin-echo T2 fat-saturated, and coronal turbo spin-echo proton density fat-saturated images. Whole-pelvis coronal T1 and STIR sequences were also performed. Patients received IV gadolinium contrast material and exercised for 15 minutes. Gadolinium-enhanced fat-saturated T1 sequences were obtained in three planes. Arthroscopy was performed by two orthopedic surgeons who specialize in treating hip disorders. Cases were then retrospectively reviewed by two experienced musculoskeletal radiologists who were blinded to the arthroscopic findings. Cases were examined for acetabular labral tears and chondral lesions. Extraarticular findings of femoral acetabular impingement were recorded. Unenhanced and gadolinium-enhanced images of the labrum were compared for differences and changes in diagnosis. Comparison was made between the arthroscopic and MR findings for analysis of the results. RESULTS: Of the 13 labral tears found at arthroscopy, 85% were detected by conventional MRI, whereas 100% were identified via indirect MR arthrography. Seventy percent of the labral tears identified on conventional MRI were better delineated by indirect MR arthrography. Identification of chondral abnormalities was not improved via indirect MR arthrography over conventional MRI. CONCLUSION: IV contrast-enhanced indirect MR arthrography appears to be an effective means of hip evaluation for labral tears. It does not appear to improve detection of cartilage abnormalities when compared with conventional MRI.

RESUMO

La ectasia vascular gástrica antral es una entidad reconocida clínica e histopatológicamente, de etiología no precisada, siendo a su vez una causa infrecuente de sangrado digestivo crónico o agudo. Existen muy pocos casos clínicos documentados en la literatura. Existen variadas formas de enfrentar esta patología, existiendo consenso que las más exitosas son la cirugía invasiva y/o terapia endoscópica ND:YAG láser. Se presenta un caso clínico de una mujer de 70 años atendida en nuestro hospital en el cual no contamos con terapia endoscópica, siendo sometida a tratamiento quirúrgico convencional (Antrectomía) con buen resultado.

RESUMO

Se presenta un estudio electrocardiográfico, hecho en 2.130 donantes de bancos de sangre, en la ciudad de Bucaramanga, Colombia, entre los años 1999 y 2004. Se comparan los hallazgos entre 486 seropositivos T (+) y 1.644 seronegativos T (-) para Tripanosoma Cruzi. Se encontraron diferencias porcentuales estadísticamente significativas en la población T (+) con relación a los T (-) en los siguientes parámetros: bloqueo de rama derecha (6,1/2,6 p<0,001), hemibloqueo izquierdo anterosuperior (5,7/2,3 p<0,001), bloqueo aurículo-ventricular (2,7/1 p=0,006), extrasístoles ventriculares (2,5/0,9 p=0,009), aplanamiento o inversión de la onda T (16,4/10,8 p=0,001) y PR limítrofe (6,9/4,1 p=0,009). Del mismo modo, se encontraron diferencias significativas a favor del grupo T (-) en cuanto a patrón de bloqueo de rama derecha (9,9/5,9 p=0,007) y trastornos inespecíficos de la conducción (42,5/34,1 p=0,001). No se encontró diferencia estadísticamente significativa en cuanto a presentar extrasistolia supraventricular u ondas Q patológicas. Igualmente, si se asocian los trastornos de conducción y del ritmo, poseer al menos uno de ellos ocurre más en el grupo T (+) (16,8/11,3 p<0,001) y es aún más significativo si se presentan dos o más trastornos asociados (3,0/0,9 p<0,001).

RESUMO

The purpose of this prospective study was to determine the level of interobserver and intraobserver agreement among orthopedic surgeons and radiologists when computed tomography (CT) scans are used with plain radiographs to evaluate intertrochanteric fractures. In addition, the prognostic value of current classifications systems concerning quality of life was evaluated. Sixty-one patients who presented with intertrochanteric fractures received open reduction and internal fixation with compression hip screw. Three orthopedic surgeons and 2 radiologists independently classified the fractures according to 2 systems: Evans-Jensen and AO (Arbeitsgemeinschaft für Osteo-synthesefragen). Fractures were initially graded with plain radiographs and then again in conjunction with CT. Results were analyzed using the (kappa) kappa coefficient. The 36-item Short-Form Health Survey was administered at baseline, 3 months, and 1 year, and results were correlated with fracture grade. Mean kappa coefficients when comparing radiography alone with radiography and CT scan were 0.63 for the AO system and 0.59 for the Evans-Jensen system. Both represent "fair" agreements. Mean overall interobserver kappa coefficients were 0.67 for radiologists and 0.57 for orthopedic surgeons. Radiologists also had higher intraobserver kappa coefficients. No significant relationships were found between follow-up Short Form Health Survey results and intraoperative grading of fractures. When these classification schemes are compared, interobserver agreement does not appear to change dramatically when information from CT scans is added. This may suggest that (1) more data have been provided by CT with greater possibilities for misinterpretation and (2) these classification schemes may not be comprehensive in describing fracture pattern and displacement. Finally, both systems failed to provide any prognostic value.

RESUMO

This prospective randomized trial compared the efficacy of unipolar versus bipolar hemiarthroplasty in elderly patients (> or = 65 years) with displaced femoral neck fractures in terms of quality of life and functional outcomes. One hundred fifteen patients with a mean age of 82.1 years were enrolled in this study and randomized to either unipolar or bipolar hemiarthroplasty. Quality of life and functional outcomes were assessed using the Musculoskeletal Functional Assessment instrument and Short Form-36 health survey. Seventy-eight patients completed 1 year of followup. There were no differences between the groups in estimated blood loss, length of hospital stay, mortality rate, number of dislocations, postoperative complications, or ambulatory status at 1 year. There also were no significant differences between the two groups at either point in postoperative Short Form-36 or Musculoskeletal Functional Assessment instrument scores. Results of this prospective randomized study suggest that the bipolar endoprosthesis provides no advantage in the treatment of displaced femoral neck fractures in elderly patients regarding quality of life and functional outcomes.

RESUMO

A consecutive case series from 2 institutions of patients with postoperative wound infections after mini-open rotator cuff repair was reviewed. Between 1991 and 2000, 360 patients underwent mini-open rotator cuff repair after arthroscopic subacromial decompression. Seven patients had postoperative infection develop (1.9%). All patients were men, with a mean age of 55 years (range, 40-64 years). Treatment included serial irrigation and debridement, long-term intravenous antibiotics, and revision rotator cuff repair. Mean follow-up after definitive treatment was 32 months (range, 12-57 months). Propionibacter acnes was present in 6 of 7 patients (86%) with infections. The initial rotator cuff repair was disrupted in 4 shoulders and intact in 3. A revision rotator cuff repair was performed at the final irrigation and debridement in all 4 shoulders. Results were 100% satisfactory. The mean American Shoulder and Elbow Surgeons pain score improved from 7 (range, 6-9) preoperatively to 1 (range, 0-2). The mean final score was 95. Because these infections were noted to occur only in arthroscopically assisted rotator cuff repairs, a second preparation and draping were introduced as routine protocol. No postoperative infections have occurred in the ensuing 200 mini-open rotator cuff repairs.

RESUMO

Para conocer la casuística de lesiones canaliculares en la Fundación Hospital "Nuestra Señora de la Luz" en los últimos 10 años, y determinar el tiempo adecuado de permanencia del implante, se realizó una investigación retrospectiva y descriptiva en la que se seleccionaron 93 expedientes que incluían diagnóstico de lesión canalicular. Sesenta y tres pacientes fueron sometidos a dacriointubación bicanalicular; se utilizó la modalidad anular en 10 casos y la nasal en 53 con tubo de silicona. La extracción del tubo se documentó en 41 casos, 30 programadas y 11 accidentales. El 60 por ciento de los casos de herida palpebral se han acompañado de lesión canalicular, y su manejo es similar al reportado en la literatura actual, obteniendo buenos resultados. El tubo puede permanecer por 6 meses o más dependiendo de la evolución, y su retiro a partir de las 6 semanas.

RESUMO

Objetivo: evaluar el patrón autonómico en sujetos sometidos a dos protocolos consecutivos de mesa basculante usnado vasodilatadores sublinguales (VASO) e isoproterenol a bajas dosis (ISO). Métodos: 80 pacientes con episodio(s) sincopale(es) durante los últimos seis meses fueron aleatorizados a dos protocolos de mesa basculante con VASO (nitroglicerina 400 ug, n=40) o dinitrato de isosorbide ECG y presión arterial no invasiva. Fueron calculados RMSSD, poder total, baja y alta frecuencia normalizadas (LFn, HFn), e índice LF/HF en reposo (5 min) y a 60 grados (primeros 3 min). La sensibilidad barorrefleja (analisis espectral cruzado), con coherencia y fase, el índice a de baja y alta frecuencia (aLF-aHF) y el retardo barorreflejo fueron calculados en reposo (5 min) y a 60 grados (5-10 min). Los pacientes fueron analizados en grupos de acuerdo con su respuesta a la prueba: 1) VASO+/ISO-,2)VASO-/ISO+,3)VASO+/ISO+ y 4)VASO-/ISO-. Resultados: se encontraron diferencias estadistícamente significativas (p<0.05) en ereposo entre los grupos 1 y 2 en LF/HF (1.04ñ0.14 vs 2.66ñ0.10), aHF (23.02ñ3.2 vs 10.0ñ2.3 ms/mmHg), retardo barorreflejo (1598ñ287 vs 3473ñ880 ms). A 60 grados se encontraron diferencias significativas en LF/HF (1.26ñ1.76 vs 3.14ñ1.04), LFn (49.4ñ4.7 vs 76.1ñ3.9 ms²) y retardo barorreflejo (1740ñ215 vs 3307ñ274 ms). La utilización de ambos protocolos incremento el rendimiento diagnostico de la prueba en 30 por ciento. conclusiones: la suceptibilidad a agentes inductores puede indicar diferentes mecanismos moduladores de la respuesta refleja neurocardiogénica. Estos hallazgos fisiológicos pueden proveer información para el uso individualizado de protocolos de mesa basculante

RESUMO

El propósito de este estudio fue comparar el sellamiento apical con una técnica de inyección de gutapercha termoplastitificada, contra el de otras dos técnicas convencionales, mediante un método de filtración especialmente diseñado para este tipo de investigaciones. La muestra fue de 138 conductos, clasificados a su vez en tres grupos lo más homogéneamente posible. Dcihas muestras fueron sometidas a la técnica de filtración con azul de metileno al 2 por ciento en condiciones de vacío. Los mejores resultados de sellamiento apical con un menor promedio de filtración, fueron para la técnica lateral modificada (1.03 mm), seguidad por la técnica ultrafil (1.11 mm) y por último la técnica de condensación térmica utilizando compactadores de Mc Spadden(1.28 mm)

RESUMO

Entre Enero de 1984 y Diciembrre de 1986 en un grupo de pacientes con síntomas de reflujo gastroesofágico se estudiaron los hallazgos endoscópicos de los diferentes grados de esofagitis de acuerdo a la clasificación europea. Se encontró un 5% de pacientes con signos endoscópicos de esofagitis, siendo los mas frecuentes el Grado I (leve) o bien el hallazgo de esófago de Barrett. Sus síntomas fueron similares a lo reportado en la literatura y la distribución de edad y sexo en cada grupo de diverso grado de esofagitis no fueron significativamente diferentes. El cambio de mucosas escamosas o columnar se encontró significativamente más alto en pacientes con esofagitis Grado III y IV
