Resumen

Background. Inflammation has been considered to play an important role in the pathogenesis of the thoracic ossification of the ligamentum flavum (OLF). However, the inflammation-related risk factors of thoracic OLF have not been fully investigated to date. Methods. A total of 95 patients (48 in the OLF group and 47 in the control group) were included in this retrospective study to explore the independent risk factors of thoracic OLF. The following demographic and clinical variables were compared between the two groups: gender, age, body mass index (BMI), coexistence of hypertension or diabetes, and inflammation-related variables. Multivariate logistic regression analysis was utilized to determine the independent risk factors. Results. High systemic immune-inflammation index (SII) (≥621) (odds ratio OR = 12.16 , 95% confidence interval CI = 2.95 – 50.17 , p < 0.01 ) and BMI (≥25 kg/m2) ( OR = 9.17 , 95 % CI = 3.22 – 26.08 , p < 0.01 ) were independent risk factors of thoracic OLF. SII ( R = 0.38 , p < 0.01 ) and BMI ( R = 0.46 , p < 0.01 ) were positively associated with OLF score. Conclusion. High SII and BMI were the independent risk factors of thoracic OLF. Multicenter prospective studies with a large population should be conducted in the future to verify our findings.

Resumen

The amount of collectable blood during the early phase of slaughter was determined for 48 lambs in 4 treatment groups: a control group (no current, no thoracic stick), a thoracic stick group only and groups subjected to a thoracic stick and either an electric current of 14 or 10 Hz frequency. The current was applied to the ‘skin-on’ carcass soon after the stunning/sticking process and subsequent to the thoracic stick, with a view to increasing the volume of blood released at that time. With both frequencies there was a small, but statistically significant (P<0.05), increase in the amount of released blood over non-stimulated treatments. Samples of M. longissimus thoracis et lumborum were aged for 1 and 5 days before freezing. Warner–Bratzler shear force measurements indicated the effectiveness of the current applications in reducing shear force with the 14 Hz waveform being superior to the 10 Hz waveform and in a related way the degradation of myofibrillar proteins was greater in meat subjected to the 14 Hz treatment when examined using the myofibrillar fragmentation index.

Resumen

The breeding of creole cattle from the southern region of Ecuador, also known as Criollo Lojano, is a source of economic support and work for the communities located in the remote areas of the Andes mountains in this region. These cattle are grouped into four biotypes based on their phenotypic characteristics: Negro Lojano, Encerado, Colorado, and Cajamarca or Pintado. This study analyzes the morphometric variability of these creole cattle using least squares means (LSM) and restricted maximum likelihood Restricted Maximum Likelihood (REML) variance components. The evaluation parameters used to characterize these cattle were live weight plus 15 morphometric characteristics and nine morphometric indexes. The measurements came from 151 adult animals (28 male and 123 females). With the exception of Height at Withers (P = 0.06), the other morphometric characteristics do not show significant difference among these creole biotypes. Sexual dimorphism was found in live weight, thoracic circumference, height at withers, chest width, length of thorax, length of body, depth of thorax, depth of abdomen, length of head, and length of horns (P < 0.05). The adult Creole Lojano has an average live weight of 288 ± 12.9 kg (mean ± standard error), The Cephalic index is 45.6, the Corporal index is 115.9, the Pelvic index is 90.5, the Thoracic index is 58.3, the Proportionality index is 62.6, the Thoracic Capacity index is 2.1, the Lower Leg–Thoracic index is 9.9, the Transverse Pelvic index is 34.7, and the Pelvic Length index is 38.4. This creole bovine breed presents 4 biotypes that are similar; there are differences in the analysis with respect to sex (males are higher in 10 of the 16 characteristics analyzed); and on the basis of the indexes, this animal is small, has a triangular head, is longilinear with a long and narrow hip. It is a dual-purpose milk type with the exception of the Colorado biotype which is a dual purpose meat type.

Resumen

Abstract OBJECTIVES The introduction and expansion of thoracic endovascular aortic repair (TEVAR) have revolutionized the treatment of a variety of thoracic aortic diseases. We sought to evaluate the incidence, causes, predictors and costs associated with 30-day readmission after TEVAR in a nationally representative cohort. METHODS Adult patients undergoing isolated TEVAR were identified in the National Readmissions Database from 2010 to 2014. Hospital costs were estimated by converting individual hospital charge data adjusted to 2014 consumer price indices. Multivariable logistic regression was utilized to determine hospital- and patient-level factors associated with readmissions. RESULTS A total of 24 983 TEVARs were noted during the study period; the average age of the patients was 65 ± 16 years; 40% were women. The most common indication was an intact thoracic aneurysm (43.5%), followed by aortic dissection (30.5%). The average cost of the index admission was $63 644 ± $52 312; the average hospital stay was 11 ± 14 days; the index mortality rate was 6.7%. Readmissions within 30 days occurred in 17.4% of patients. Indications for readmission were varied; the most common aetiologies were cardiac (17.8%), infectious (16.0%) and pulmonary (12.1%). On multivariable analysis, the strongest predictor of readmission was the diagnosis, with a ruptured thoraco-abdominal aneurysm having the highest readmission burden (adjusted odds ratio 2.23, 1.17–4.24; P = 0.015). Notably, hospital volume did not predict index hospital length of stay, costs or 30-day readmissions (all P > 0.10). CONCLUSIONS Annual TEVAR volume was not associated with any of the outcomes assessed. Rather, indication for TEVAR was the strongest predictor for many outcomes. As TEVAR becomes increasingly utilized, a focus on cardiac and vascular diseases may reduce readmissions and improve quality of care.

Resumen

Pulmonary hypertension could have thoracic lymphatic abnormalities caused by right ventricular failure. Since there is no description of such abnormalities, the purpose of this study was to investigate them with magnetic resonance. Prospective review magnetic resonance T2-weighted lymphangiography was performed between January 2017 and October 2019 through quantitative thoracic duct diameter, diameter index and qualitative lymphatic abnormalities types: 1 – little or none abnormalities, 2 – abnormalities in supraclavicular region, 3 – abnormalities extending into the mediastinum and 4 – abnormalities extending into the lung. Five patients with group 1 pulmonary arterial hypertension participated in this study. The mean age was 12.44 ± 4.92 years, three male and two female. The quantitative analysis yielded the following results: mean thoracic duct diameter of 2.92 ± 0.16 mm and thoracic duct index 2.28 ± 1.03 mm/m2. Qualitative lymphangiography abnormalities were type 1 in three patients, type 2 in one, all with low-risk determinants, and type 3 in one with high-risk determinants and right ventricular failure. Magnetic resonance T2-weighted lymphangiography in group 1 paediatric pulmonary arterial hypertension allowed for the identification of the thoracic duct, which was used to perform both quantitative and qualitative analysis of thoracic lymphatic abnormalities, in particular when increased high-risk determinants and right ventricular failure were present. These features represent an extracardiac finding useful to understand systemic venous congestion impact on lymphatic system.

Resumen

ObjectiveTo evaluate the reliability of stroke volume variation (SVV) for predicting responsiveness to fluid therapy in patients undergoing cardiac and thoracic surgery.DesignSystematic review and meta-analysis.Data sourcesPubMed, EMBASE, Cochrane Library, Web of Science up to 9 August 2020.MethodsQuality of included studies were assessed with the Quality Assessment of Diagnostic Accuracy Studies-2 tool. We conducted subgroup analysis according to different anaesthesia and surgical methods with Stata V.14.0, Review Manager V.5.3 and R V.3.6.3. We used random-effects model to pool sensitivity, specificity and diagnostic odds ratio with 95% CI. The area under the curve (AUC) of receiver operating characteristic was calculated.ResultsAmong the 20 relevant studies, 7 were conducted during thoracic surgery, 8 were conducted during cardiac surgery and the remaining 5 were conducted in intensive critical unit (ICU) after cardiac surgery. Data from 854 patients accepting mechanical ventilation were included in our systematic review. The pooled sensitivity and specificity were 0.73 (95％ CI: 0.59 to 0.83) and 0.62 (95％ CI: 0.46 to 0.76) in the thoracic surgery group, 0.71 (95％ CI: 0.65 to 0.77) and 0.76 (95％ CI: 0.69 to 0.82) in the cardiac surgery group, 0.85 (95％ CI: 0.60 to 0.96) and 0.85 (95％ CI: 0.74 to 0.92) in cardiac ICU group. The AUC was 0.73 (95% CI: 0.69 to 0.77), 0.80 (95% CI: 0.77 to 0.83) and 0.88 (95% CI: 0.86 to 0.92), respectively. Results of subgroup of FloTrac/Vigileo system (AUC=0.80, Youden index=0.38) and large tidal volume (AUC=0.81, Youden index=0.48) in thoracic surgery, colloid (AUC=0.85, Youden index=0.55) and postoperation (AUC=0.85, Youden index=0.63) in cardiac surgery, passive leg raising (AUC=0.90, Youden index=0.72) in cardiac ICU were reliable.ConclusionSVV had good predictive performance in cardiac surgery or ICU after cardiac surgery and had moderate predictive performance in thoracic surgery. Nevertheless, technical and clinical variables may affect the predictive value potentially.

Resumen

This semestral thesis deals with continuous monitoring of pulmonary ventilation during the patients' theraphy and focuses especially on monitoring of their ventilation processes. It is necessarry to detect, monitor and differentiate abdominal and thoracic breathing during the theraphy. This thesis describes the very basic and common method, a spirometry. Next, an overview of more advanced state-of-the-art methods based on both, tactile and proximity principles is given. In addition to that, two recently developed methods by BUT are discussed as well -- a tactile-based measurement similar to blood pressure sensor and a proximity-based measurement method employing TOF cameras. The data acquired by these two methods are proccesed and examined in order to evaluate and justify their performance in a real application.

Resumen

Mechanism, patient presentation, and physical exam are key elements to accurate and prompt diagnosis of thoracic injury. A high proportion of poly-trauma victims suffer thoracic injury which is associated with mortality of with 25-50%. Initial management is guided by ATLS principles of Airway, Breathing, and Circulation. The FAST (focused assessment with sonography for trauma) exam plays a key role in the initial evaluation of thoracic trauma. Most injuries to the thoracic cavity may be managed non-operatively or with bedside procedures with the caveat that patients with thoracic injury require close attention and monitoring in the ICU for potential deterioration. A high index of suspicion is paramount to successful patient care. When operative intervention is required it is often emergent.
