There is a deep need for mortality predictors that allow clinicians to quickly triage patients with severe coronavirus disease 2019 (Covid-19) into intensive care units at the time of hospital admission. Thus, we examined efficacy lymphocyte-to-neutrophil ratio (LNR) and neutrophil-to-monocyte (NMR) as in-hospital death admission in Covid-19. A total 54 Mexican adult Covid-19 met hospitalization criteria were retrospectively enrolled, followed-up daily until discharge or death, then assigned...
COVID-19 is primarily a respiratory disease; however, there also evidence that it causes endothelial damage in the microvasculature of several organs. The aim present study to characterize vivo microvascular reactivity peripheral skeletal muscle severe patients.This prospective observational carried out Spain, Mexico and Brazil. Healthy subjects patients admitted intermediate (IRCU) intensive care units (ICU) due hypoxemia were studied. Local tissue/blood oxygen saturation (StO2) local...
Abstract Background Wound healing monitoring and timely decision‐making are critical for wound classification. Tryptophan (Tr) intrinsic fluorescence, detected at 295/340 nm, provides a noninvasive approach assessment. Our previous work demonstrated that this autofluorescence is associated with keratinocytes in highly proliferative state vitro. Objective We investigated the correlation between Tr fluorescence key parameters, including re‐epithelialization, fibrosis, neovascularization, acute...
Abstract Background The quantitative interpretation of the radiometric information extracted from infrared (IR) images in individuals with and without type 2 diabetes mellitus (DM2) is an open problem yet to be solved. This particular value given that DM2 a worldwide health onset for evolution toward diabetic foot disease (DFD). Since causes changes at vascular neurological levels, metabolic heat distribution on outer skin modified as consequence such alterations. Of interest this...
Abstract Multiple studies have established that hyperinflammatory response induced by SARS CoV-2 is a main cause of complications and death in infected subjects. Such dysfunctional immune has been described as dysregulated exacerbated production cytokines chemokines attracts activates inflammatory cells, which start sustain pulmonary systemic damage, thus causing lead to multi organ failure death. Therefore, we suggest blocking key inflammation receptors could help reduce migration...
We present advancements on the analysis of infrared (IR) images lower limbs patients with diabetic foot disease (DFD). Our task is to study and identify alterations in heat emission as result DFD. This performed through calculation Spearman's correlation coefficient. As we found natural asymmetry values non-diabetic controls 12%(±7%) 24%(±16%) for front back views limbs, respectively. In evaluated observed a remarkable tendency towards outside range found. For purpose validating consistency...

A proof-of-concept study using thrombolysis with catheter-directed tissue plasminogen activator (tPA) and pulmonary angiography imaging was performed to visualize perfusion deficits reperfusion/therapeutic effects of tPA.A prospective, open-label, compassionate study. Descriptive statistics were presented for categorical variables as means sds continuous variables. The Wilcoxon test used determine the differences between two-related samples a t Statistical significance set at p value less...

We report a methodology to analyze data extracted from infrared images. These pictures show the lower limbs of cohort individuals belonging to, (1) voluntary controls and (2) patients diagnosed with diabetes mellitus type II. The analysis is presented in terms Cross Entropy temperature distributions; both using associated thermal histograms. placed comparing extreme values ofdS/dQ, for patients. In this frontal view, specificity sensitivity calculated were 77.77% 91.66%, respectively. For...
The purpose of the study we report is to extract radiometric information, distributed in three regions interest (ROI's), from legs patients clinically diagnosed with Diabetes Mellitus Type II (DM2) and a control group. We analyze asymmetry thermal radiation emitted through two approaches: 1) comparing higher lower temperatures probability distribution each leg 2) computing an index based on Spearman's correlation coefficient; that for both groups views: anterior (AV) posterior (PV). results...
Diabetic foot disease (DFD) is one of the major complications Diabetes Mellitus; within which Neurophaty (DN) and peripheral vascular (PVD) (arteriosclerosis mainly) are among most important causal factors in pathogenesis diabetic ulcers. Once ulcers present, risk limb amputation extremely high. A side effect from DN PVD change rate release metabolic heat at quite specific areas. Here we present early advancements on pattern recognition infrared imagenology (thermography) picturing altered...
Among the WHO, goals for 2030 are to detect >90% of people with HCV and link >80% treatment. Our institution serves an open population without social security. This study aimed describe detection strategy that was carried out in population, using two-step tests at "Hospital General de México" from January December 2021. The conducted transits our hospital any reason agreed take risk factor questionnaire rapid test anti-HCV antibodies (RT); those who were reactive underwent viral load (PCR...
We study the environmental thermal noise effect on biomedical infrared imaging.The approach to discriminate from natural metabolic variability, rely initial reconsignment of contra-lateral asymmetry between human lower limbs.Then we disambiguate this information or background noise, by distinguishing its magnitude and spectral characteristics in Fourier-space.From analysis one can unveil kind characteristics, remove it correct radiometric data improve their true values.1.

Abstract Background : Multiple studies have now established that hyperinflammatory response induced by SARS CoV-2 is a main cause of complications and death in infected subjects. Such dysfunctional immune has been described as dysregulated exacerbated production cytokines chemokines attracts activates inflammatory cells, which start sustain pulmonary systemic damage, thus causing lead to multi organ failure death. Therefore, we suggest blocking key inflammation receptors could help reduce...
In this work we introduce a standard framework to represent abnormal conditions related metabolic syndrome (MetS). This is based on percentiles represented by reference ellipses constructed from population, and it allows us observe drifts respect references caused MetS.
