Human intestinal microbiome: Role in health and disease.

The study of the microbiota and the microbiome, and specifically the intestinal one, has determined great interest due to the possible association of their alterations with numerous diseases. These include entities as diverse as Crohn's disease, autism, diabetes, cancer or situations as prevalent today as obesity. In view of this situation, different recommendations have been performed regarding the use of probiotics, prebiotics, and postbiotics as modulators of the microbiota and the microbiome, seeking both preventive and therapeutic effects, and faecal material transfer (FMT) is proposed as an alternative. The latter has emerged as the only proven beneficial intervention on the intestinal microbiome, specifically in the treatment of recurrent colitis associated with Clostridioides difficile (R-CDI). In the rest of the entities, the lowering of laboratory costs has favored the study of the microbiome, which is resolved by delivering reports with catalogs of microorganisms, metabolites or supposed biomarkers without consensus on their composition associated with healthy or diseased microbiota and the disease. There is still insufficient evidence in any disease for interventions on the microbiome beyond FMT and R-CDI. Multi- and multi-disciplinary work with extensive research and the application of artificial intelligence in this field may shed light on the questions raised currently. Ethical issues must also be resolved in light of possible interventions within the umbrella of personalized medicine.

[Usefulness of the MPB-INFURG-SEMES model to predict bacteremia in the patient with solid tumor in the Emergency Department]. / Utilidad del modelo MPB-INFURG-SEMES para predecir bacteriemia en el paciente con neoplasia sólida en el Servicio de Urgencias.

OBJECTIVE: To analyse a new risk score to predict bacteremia (MPB-INFURG-SEMES) in the patients with solid tumor attender for infection in the emergency departments (ED). METHODS: Prospective, multicenter observational cohort study of blood cultures (BC) obtained from adult patients with solid neoplasia treated in 63 EDs for infection from November 1, 2019, to March 31, 2020. The predictive ability of the model was analyzed with the area under the Receiver Operating Characteristic curve (AUC-ROC). The prognostic performance for true bacteremia was calculated with the chosen cut-off for getting the sensitivity, specificity, positive predictive value and negative predictive value. RESULTS: A total of 857 blood samples wered cultured. True cases of bacteremia were confirmed in 196 (22.9%). The remaining 661 cultures (77.1%) wered negative. And, 42 (4.9%) were judged to be contaminated. The model's area under the receiver operating characteristic curve was 0.923 (95% CI,0.896-0.950). The prognostic performance with a model's cut-off value of ≥ 5 points achieved 95.74% (95% CI, 94,92-96.56) sensitivity, 76.06% (95% CI, 75.24-76.88) specificity, 53.42%(95% CI, 52.60-54.24) positive predictive value and 98.48% (95% CI, 97.66- 99.30) negative predictive value. CONCLUSIONS: The MPB-INFURG-SEMES score is useful for predicting bacteremia in the adults patients with solid tumor seen in the ED.

Relationship between quality of life, emotional symptomology and perceived emotional intelligence in a sample of burn victims.

The main objective of this study is to analyse the association between Quality of Life (QOL), Emotional Symptomology and perceived Emotional Intelligence (EI) in burn patients. Additionally, it is intended determine the predictor models of QOL, and confirm the mediating effect of emotional symptomology between QOL and perceived EI. This is a transversal study developed in the Hospital da Prelada, Porto, Portugal, with a sample of 92 patients that were hospitalized in the Burn Unit and the Reconstructive Plastic Surgery Service. The assessment protocol consisted of a sociodemographic and clinical data sheet. To assess the perception of QOL of the burn patient it was used the Burn Specific Health Scale - Revised (BSHS-R), the emotional symptomology was measured by the Brief Symptom Inventory (BSI) and Trait Met-Mood Scale-24 (TMMS) was used to assess Emotional Intelligence (EI). The cross-sectional and correctional data were analysed through descriptive statistics, correlations, regressions and simple mediations. The results obtained suggest significant associations between QOL, perceived EI and Emotional Symptomology in burn patients. The results of the predictor models of the QOL domains encompass the Positive Symptom Distress Index (PSDI of Emotional Symptomology), where the total variance is explained mainly by the models of QOL Affect and Body Image 46% and Treatment 31%. The mediating effect of the PSDI in the relationship between QOL in the Affect and Body Image dimension and the Mood Repairs (MR) was also tested, having proved to have a total mediation (the Mood Repairs loses its contribution in the QOL model when the PSDI variable is introduced). This study underscores the importance of perceived Emotional Intelligence and its association with the burn impact in the different dimensions of QOL of the patients. The intention of this study is to alert health professionals for patient support in the search for strategies that aim for positive adaptation which promotes QOL and emotional adjustment of burn patients to their new condition.

[Diagnostic accuracy of procalcitonin for bacteremia in the emergency department: a systematic review]. / Precisión diagnóstica de la procalcitonina para la bacteriemia en el servicio de urgencias: una revisión sistemática.

OBJECTIVE: Obtaining blood cultures (HC) is performed in 15% of the patients treated with suspicion of infection in the Hospital Emergency Services (ED) with a variable diagnostic yield (2-20%). The 30-day mortality of patients with bacteremia is two or three times higher than the rest with the same process. Procalcitonin (PCT) is a biomarker that has been used as a tool to help predict bacteremia in HEDs. The main objective of this systematic review is to investigate the diagnostic accuracy of PCT in predicting true bacteraemia in adult patients treated with clinical suspicion of infection in the ED, as well as to identify a specific PCT value as the most relevant from the clinical decision diagnostic point of view that can be recommended for decision making. METHODS: A systematic review was performed following the PRISMA guidelines in the PubMed, Web of Science, EMBASE, Lilacs, Cochrane, Epistemonikos, Tripdatabase and ClinicalTrials.gov databases from January 2010 to May 31, 2023 without language restrictions and using a combination of MESH terms: "Bacteremia/ Bacteraemia/ Blood Stream Infection", "Procalcitonin", "Emergencies/ Emergency/ Emergency Department" and "Adults". Observational cohort studies and partially an systematic review were included. No meta-analysis techniques were performed, but the results were compared narratively. RESULTS: A total of 1,372 articles were identified, of which 20 that met the inclusion criteria were finally analyzed. The included studies represent a total of 18,120 processed HC with 2,877 bacteraemias (15.88%). Ten studies were rated as high, 9 moderate and 1 low quality. The AUC-COR of all the studies ranges from 0.68 (95% CI: 0.59-0.77) to 0.98 (95% CI: 0.97-0.99). The PCT value >0.5 ng/ml is the most widely used and proposed in up to ten of the works included in this systematic review, whose estimated mean yield is an AUC-COR of 0.833. If only the results of the 6 high-quality studies using a cut-off point (PC) >0.5 ng/mL PCT are taken into account, the estimated mean AUC-COR result is 0.89 with Se of 77.6% and It is 78%. CONCLUSIONS: PCT has a considerable diagnostic accuracy of bacteraemia in patients treated in EDs for different infectious processes. The CP>0.5 ng/ml has been positioned as the most suitable for predicting the existence of bacteraemia and can be used to reasonably rule it out.

[Utility of the medial region of pro-adrenomodulin for the detection of true bacteremia in elderly patients treated in the emergency department for suspected infection]. / Utilidad de la región medial de la pro-adrenomodulina para la detección de bacteriemia verdadera en pacientes mayores atendidos en urgencias por sospecha de infección.

OBJECTIVE: The prediction of bacteremia in the emergency department (ER) is important for initial decision-making. The elderly population is a diagnosis challenge. The objective was to evaluate the accuracy of mid regional pro-adrenomedullin (MR-proADM) to identify true bacteremia (BV) in elderly patients attended in 3 hospital emergency departments. METHODS: Observational study including patients ≥75 years of age or older attended in the ER for suspected infection in whom a blood culture (BC) was extracted. Sociodemographic, comorbidity, hemodynamic and analytical variables, biomarkers [MR-proADM, procalcitonin (PCT), C-reactive protein (CRP) and lactate] and final diagnosis were collected. The primary outcome was a true positive on a blood culture. RESULTS: A total of 109 patients with a mean age of 83 (SD: 5.5) years were included. A final diagnosis of BV was obtained in 22 patients (20.2%). The independent variables to predict it were PCT (OR: 13.9; CI95%: 2.702-71.703; p=0.002), MR-proADM (OR: 4.081; CI95%: 1.026-16.225; p=0.046) and temperature (OR: 2.171; CI95%: 1.109-4.248; p=0.024). Considering the cut-off point for MR-proADM (2.13 mg/dl), a sensitivity (Se) of 73%, specificity (E) of 71%, a positive predictive value (PPV) of 39%, a negative predictive value (NPV) of 91%, a positive likelihood ratio (LHR+) of 2.53 and a negative likelihood ratio (LHR-) of 0.38; for PCT (0.76 mg/dl) a Se of 90%, E of 65%, PPV of 40%, NPV of 96%, LHR+ 2,64 and a LHR- of 0.14 were obtained. When combining both, a Se of 69%, E of 84%, PPV of 52%, NPV of 91%, LHR+ of 4.24 and LHR- of 0.38 were observed. CONCLUSIONS: Elevated levels of PCT and MR-proADM were independently associated with an increased risk of BV and the combination of both improves the accuracy to identify these patients.

Tuberculosis in Spain: An opinion paper.

This document is the result of the deliberations of the Committee on Emerging Pathogens and COVID-19 of the Illustrious Official College of Physicians of Madrid (ICOMEM) regarding the current situation of tuberculosis, particularly in Spain. We have reviewed aspects such as the evolution of its incidence, the populations currently most exposed and the health care circuits for the care of these patients in Spain. We have also discussed latent tuberculosis, the reality of extrapulmonary disease in the XXI century and the means available in daily practice for the diagnosis of both latent and active forms. The contribution of molecular biology, which has changed the perspective of this disease, was another topic of discussion. The paper tries to put into perspective both the classical drugs and their resistance figures and the availability and indications of the new ones. In addition, the reality of direct observation in the administration of antituberculosis drugs has been discussed. All this revolution is making it possible to shorten the treatment time for tuberculosis, a subject that has also been reviewed. If everything is done well, the risk of relapse of tuberculosis is small but it exists. On the other hand, many special situations have been discussed in this paper, such as tuberculosis in pediatric age and tuberculosis as a cause for concern in surgery and intensive care. The status of the BCG vaccine and its present indications as well as the future of new vaccines to achieve the old dream of eradicating this disease have been discussed. Finally, the ethical and medicolegal implications of this disease are not a minor issue and our situation in this regard has been reviewed.

Sexually transmitted infections in Spain: Current status.

Sexually Transmitted Infections (STI) are a major public health problem. The problems inherent to their diagnosis, treatment and prevention have to do not only with their nature, but also with organizational issues and overlapping competencies of the different health authorities in Spain. The real situation of STI in Spain, at present, is poorly known. For this reason, the Scientific Committee on COVID and Emerging Pathogens of the Illustrious Official College of Physicians of Madrid (ICOMEM) has formulated a series of questions on this subject which were distributed, not only among the members of the Committee, but also among experts outside it. The central health authorities provide very high and increasing figures for gonococcal infection, syphilis, Chlamydia trachomatis infection and lymphogranuloma venereum (LGV). Both HIV infection and Monkeypox are two important STI caused by viruses in our environment, to which it should be added, mainly, Herpes simplex virus (HSV) and Human papillomavirus (HPV) infections. Emerging microorganisms such as Mycoplasma genitalium pose not only pathogenic challenges but also therapeutic problems, as in the case of N. gonohrroeae. The pathways that patients with suspected STI follow until they are adequately diagnosed and treated are not well known in Spain. Experts understand that this problem is fundamentally managed in public health institutions, and that Primary Care and Hospital Emergency Services, together with some institutions that deal monographically with this problem, are the recipients of most of these patients. One of the most serious difficulties of STI lies in the availability of the microbiological tests necessary for their diagnosis, particularly in this era of outsourcing of microbiology services. Added to this is the increased cost of implementing the latest generation of molecular techniques and the difficulties of transporting samples. It is clear that STI are not diseases to which the entire population is equally exposed and it is necessary to have a better knowledge of the risk groups where to focus the necessary interventions adapted to their characteristics. It should not be forgotten that STI are also a problem in the pediatric age group and that their presence can be a marker of sexual abuse with all that this implies in terms of health care and medicolegal activity. Finally, STI are infections that are associated with a high cost of care for which we have very little information. The possibility of expanding the automatic performance of laboratory tests for STI surveillance through laboratory routines is encountering ethical and legal problems that are not always easy to solve. Spain has created a ministerial area of specific attention to STI and there are plans to improve the diagnosis, treatment and prevention of these problems, but we still lack the necessary evidence on their impact. We cannot forget that these are diseases that transcend the individual and constitute a Public Health problem.

IMPULSE Study: Impact of COVID-19 in the present of ophthalmology focusing on ocular surface and future trends.

INTRODUCTION AND OBJECTIVE: Digital evolution represents an opportunity for ophthalmology to adapt to new care models. This study aimed to find out how the pandemic has modified the clinical practice and training activities of the ophthalmologist specialised in ocular surface, as well as to analyse emerging trends and needs. MATERIALS AND METHODS: This study was carried out through an online survey. A committee of 3 specialists developed a questionnaire of 25 questions structured in: 1) Participant profile; 2) Impact of the pandemic on patient management and professional activities; 3) Trends and needs. RESULTS: 68 clinical ophthalmologists participated. There was a high degree of agreement (90%) that the pandemic has delayed ophthalmological follow-up visits and diagnosis. The participants agreed that the frequency of patients with dry eye disease (75%), stye/chalazion (62%) and blepharitis (60%) has increased. According to 28%, remote monitoring of pathologies such as dry eye, glaucoma, diabetes, conjunctivitis, hyposphagmas, styes, etc., will be common, especially in the young population. This will be especially relevant in chronic or mild pathologies of the ocular surface, and in the follow-up of patients after cataract and diabetic retinopathy interventions. CONCLUSIONS: During the pandemic, an increase in the incidence of certain ocular surface diseases has been perceived. The telematic follow-up of chronic or mild pathologies of the ocular surface entails the need to provide specific training for both the patient and the healthcare professional, in addition to screening and referral protocols that would optimise the flow of care.

Usefulness of monocyte distribution width (MDW) as a sepsis biomarker.

Sepsis is one of the main causes of mortality in the emergency department (ED), due to the fact that signs and symptoms are common to other acute diseases, and this can result in delayed detection. This diagnostic complexity has a huge impact on an entity in which early recognition determined treatment, as wells as enhance the patient's prognosis. Therefore, it is crucial to improve early identification. Different analytical tools arise from this approach, such as biomarkers: procalcitonin, C-reactive protein or MR-proadrenomedullin. In this review we will focus on a newer biomarker, the monocyte distribution width. The main objectives are to evaluate the usefulness of monocyte distribution width (MDW) in sepsis identification in ED, its limitations, and to compare it with other biomarker.

[Experimental cadaveric study assesing protection and osteotomy guide system (BARU) in hallux valgus surgery using Reverdin-Isham technic]. / Estudio experimental cadavérico para valorar el sistema de protección y guía de osteotomía (BARU) en cirugías de hallux valgus con técnica de Reverdin-Isham.

INTRODUCTION: Hallux valgus is a high frequency disorder, affecting the first ray. Operative correction techniques have grown popularity lately. One of them is the Reverdin-Isham technique (first metatarsal medial incomplete osteotomy). Recently, a protection and osteotomy cutting guide has been developed: the BARU system. OBJECTIVE: To test the usefulness of the BARU system as a protective factor for soft structures adjacent to the surgical site and guidance for osteotomy. MATERIAL AND METHODS: Experimental cadaveric study. Six cadaveric feet (two fresh-frozen and four in formaldehyde solution), unapproached. Feet were numbered and intervened with RI technique, three of them with BARU system and three without it. Afterwards, dissection by two dissectors who did not know whether the BARU system had been used or not, establishing a single-blinded model. 13 structures were evaluated in each foot. Data was recovered into Microsoft Office Excel and processed with SPSS. 2 test (significative if p value < 0.05) and relative risk were calculated. RESULTS: Approach using BARU system was satisfactory, with usual-size operation-ports. BARU system colocation was simple and radiological control showed adequate spatial location. The device contributed as reference for cutting direction and depth. 65 out of the 78 searched structures were found (83.3%). Six injuries were found among the assessed structures: plantar medial nerve (one injury), plantar medial artery (one injury), flexor brevis muscle (three injuries), abductor muscle (one injury). Five of these injuries occurred in non-utilizing BARU system feet. CONCLUSION: Promising results in terms of protection of nearby structures, cutting guide, and ease of intervention. Avoids X-rays exposure. Not significant statistical calculations, the sample should be enlarged.

INTRODUCCIÓN: El hallux valgus es una patología con alta prevalencia en la población. Técnicas de corrección quirúrgica han crecido en popularidad últimamente. Una de ellas es la de Reverdin-Isham (RI: osteotomía incompleta medial en primer metatarsiano), se desarrolló un dispositivo de protección y guía de corte para dicho procedimiento: el sistema BARU. OBJETIVO: Probar la utilidad del sistema BARU como factor protector de estructuras blandas adyacentes al sitio de abordaje y guía para osteotomía. MATERIAL Y MÉTODOS: Estudio cadavérico; seis pies (dos frescos y cuatro formolados) sin abordajes previos. Tres con el sistema BARU y tres sin éste. Posteriormente disección por dos disectores con enmascaramiento simple ciego. Se evaluaron 13 estructuras en cada pie. Los datos fueron recabados con Microsoft Office Excel y procesados en SPSS. Se realizó test de 2 (valor p < 0.05 significativo) y se calculó el riesgo relativo. RESULTADOS: El sistema BARU fue satisfactorio. Su colocación fue sencilla y el control radiológico mostró adecuada ubicación espacial. Ayudó como referencia para la dirección y profundidad del corte. Se encontraron 65 de las 78 estructuras buscadas (83.3%). En las estructuras evaluadas hubo seis lesiones: nervio plantar medial (uno dañado), arteria plantar medial (uno dañado), músculo flexor corto (tres dañados), músculo abductor (uno dañado). Cinco de estas lesiones ocurrieron en pies donde no se utilizó el sistema BARU. CONCLUSIÓN: Resultados prometedores en cuanto a protección de estructuras cercanas, guía de corte y facilidad para la intervención. Cálculos estadísticos no significativos, la muestra debería ampliarse.

Aniridia and the ocular surface: Medical and surgical problems and solutions.

Congenital aniridia is a multisystemic genetic disease due to a mutation in PAX6 gene which severely affects the development and functionality of the human eyes. In patients affected by the mutation, aside from the absence or defects of iris tissue formation, abnormalities in position or opacities of the crystalline lens, macular hypoplasia, ocular surface disease is the main cause of visual loss and the deterioration of the quality of life of most patients. Limbal stem cell deficiency combined with tear film instability and secondary dry eye cause aniridic keratopathy which, in advanced stages, ends up in corneal opacification. In this paper, the actual knowledge about congenital aniridia keratopathy physiopathology and medical and surgical treatment options and their efficacy are discussed. Indications and results of topical treatments with artificial tears and blood-derivatives in its initial stages, and different surgical techniques as limbal stem cell transplantation, keratoplasty and keratoprostheses are reviewed. Finally, recent advances and results in regenerative medicine techniques with ex vivo stem cell cultivation or other types of cultivated cells are presented.

Combined hyperosmolarity and inflammatory conditions in stressed human corneal epithelial cells and macrophages to evaluate osmoprotective agents as potential DED treatments.

PURPOSE: To develop an easy-to-perform combined model in human corneal epithelial cells (HCECs) and Balb/c mice macrophages J774.A1 (MP) for preliminary screening of potential ophthalmic therapeutic substances. METHODS: HCECs were exposed to different osmolarities (350-500 mOsm/L) and MTT assay was employed for cell survival and flow cytometry to assess apoptosis-necrosis and relative cell size (RCS) distribution. Effectiveness of Betaine, L-Carnitine, Taurine at different concentrations (ranging from 20 mM to 200 mM) was studied. Also, mucoadhesive polymers such as Hyaluronic acid (HA) and Hydroxypropylmethylcellulose (HPMC) (0.4 and 0.8%) were evaluated. Cells were pre-incubated with the compounds (8h) and then exposed to hyperosmotic stress (470 mOsm/L) for 16h. Moreover, anti-inflammatory activity was performed in LPS-stimulated MP. RESULTS: Exposure to hyperosmotic solutions between 450 and 500 mOsm/L promoted the highest cell death after 16h exposures (p < 0.0001) with a drop in viability to 34.96% ± 11.77 for 470 mOsm/L. Pre-incubation with Betaine at 150 mM and 200 mM provided the highest cell survival against hyperosmolarity (66.01% ± 3.65 and 65.90% ± 0.78 respectively) while HA 0.4% was the most effective polymer in preventing cell death (42.2% ± 3.60). Flow cytometry showed that Betaine and Taurine at concentrations between 150-200 mM and 20-80 mM respectively presented the highest anti-apoptotic activity. Also, HA and HPMC polymers reduced apoptotic-induced cell death. All osmoprotectants modified RCS, and polymers increased their value over 100%. L-Carnitine 50 mM, Taurine 40 mM and HA 0.4% presented the highest TNF-α inhibition activity (60%) albeit all of them showed anti-inflammatory inhibition percentages higher than 20% CONCLUSIONS: HCECs hyperosmolar model combined with inflammatory conditions in macrophages allows the screening of osmoprotectants by simulating chronic hyperosmolarity (16h) and inflammation (24h).

Result of the implementation of telematic consultations in orthopaedic surgery and traumatology during COVID-19 laparoscopic surgery. / Resultado de la implantación de consultas telemáticas en cirugía ortopédica y traumatología durante la pandemia COVID-19.

The COVID pandemic has made telematic consultations a basic tool in daily practice. AIMS: The main objective of the study is to assess the results of the application of telematic consultations to limit the mobility of patients. The operational objectives are; to propose a consultation plan, to know how attendance limits consultations and to define which pathologies benefit the most from this plan. METHODS: A scheme is proposed with the creation of pre-scheduled clinic to assess suitability and the possibility of carrying them out in a single non face-to-face act. RESULTS: Phone call to 5,619 patients were made with a lack of response of 19%. The cases of 74% of the patients that answered were resolved virtually. There is a difference between units, obtaining a higher answering rate from patients appointed to specific clinic units, OR = 0.60, or to general trauma ones, OR = 0.67. The lowest answering rate was obtained from those derived from the emergency department. Twenty per cent of the consultations were not accompanied by complementary tests that would have favored the resolution in a single act. The general trauma consultations, OR = 0.34, postoperative control, OR = 0.49, and specific unit ones, OR = 0.40, were the ones that better met this requirement. Out of the remaining patients, the general trauma consultations, OR = 0.50, and those referred to units, OR = 0.54, were the ones that had a higher resolution rate without in- person consultation. CONCLUSIONS: The cases of 74% of the patients who answered the phone call were resolved virtually. Cases of 20% of the patients cannot be solved in a single act because they are derived without complementary tests. Osteosynthesis and postoperative arthroscopic follow-up consultations are the ones that need to be carried out in person the most.

[Comparison of the demographic characteristics and comorbidities of patients with COVID-19 who died in Spanish hospitals based on whether they were or were not admitted to an intensive care unit]. / Comparación de las características demográficas y comorbilidad de los pacientes con COVID-19 fallecidos en hospitales españoles, en función de si ingresaron o no en Cuidados Intensivos.

OBJECTIVE: To describe and compare the demographic characteristics and comorbidities of patients with COVID-19 who died in Spanish hospitals during the 2020 pandemic based on whether they were or were not admitted to an intensive care unit (ICU) prior to death. METHODS: We performed a secondary analysis of COVID-19 patients who died during hospitalization included by 62 Spanish emergency departments in the SIESTA cohort. We collected the demographic characteristics and comorbidities, determined both individually and estimated globally by the Charlson index (ChI). Independent factors related to ICU admission were identified and different analyses of sensitivity were performed to contrast the consistency of the findings of the principal analysis. RESULTS: We included the 338 patients from the SIESTA cohort that died during hospitalization. Of these, 77 (22.8%) were admitted to an ICU before dying. After multivariate adjustment, 3 out of the 20 basal characteristics analyzed in the present study were independently associated with ICU admission: dementia (no patients with dementia who died were admitted to the ICU: OR = 0, 95%CI = not calculable), active cancer (OR = 0.07; 95%CI = 0.02-0.21) and age (< 70 years: OR = 1, reference; 70-74 years: OR = 0.21; 95%CI = 0.08-0.54; 75-79 years: OR = 0.21; 95%CI = 0.08-0.54; ≥ 80 years: OR = 0.02; 95%CI = 0.01-0.05). The probability of ICU admission significantly increased in parallel to the ChI, even after adjustment for age (ChI 0 points: OR = 0, reference; ChI 1 point: OR = 0.36; 95%CI = 0.16-0.83; ChI 2 points: OR = 0.36; 95%CI = 0.16-0.83; ChI >2 points: OR = 0.09; 95%CI = 0.04-0.23). The sensitivity analyses showed no gross differences compared to the principal analysis. CONCLUSIONS: The profile of COVID-19 patients who died without ICU admission is similar to that observed in the usual medical practice before the pandemic. The basal characteristics limiting their admission were age and global burden due to comorbidity, especially dementia and active cancer.

[Development of a predictive model for hospital mortality and re-admission in a cohort of infected patients that require hospitalization]. / Desarrollo de un modelo predictivo para mortalidad y otro para reingreso hospitalario en una cohorte de paciente con infección que requieren hospitalización.

OBJECTIVE: The aims of the study were: to develop a predictive model for hospital mortality and another for hospital re-admission, to identify the impact of antibiotic delay in the mortality rate and, to report the rate of inappropriate antibiotic therapy. METHODS: A cohort and retrospective study was conducted at the HM Sanchinarro University Hospital during the period September 1st, 2012 to March 31th, 2013. The inclusion criteria were: age> 18 years, hospital admission from the ED with a diagnosis of bacterial infection. The exclusion criteria were: suspected viral infection, negative bacteriological cultures, life expectancy less than 6 months, lack of clinical information, assistance exclusively by the trauma emergency department. Two logistic models were made (hospital mortality and hospital re-admission). RESULTS: A total of 517 patients were included. The final mortality model (30 deaths) include the following variables: respiratory rate (OR 1.12; IC95% 1.02; 1.22), oxygen saturation (OR 0.92; IC95% 0.87; 0.98), creatinine (OR 2.33; IC95% 1.62; 3.36), COPD (OR 3.02; IC95% 1.06; 8.21), cancer (OR 3.34; IC95% 1.07; 9.98) and chemotherapy in the last 3 months (OR 4.83; IC95% 1.54; 16.41). The final model for hospital re-admission (28 re-admissions) include the following variables: hepatopathy (OR 5.51; IC95% 1.57; 16.88), GPT (OR 1.005; IC95% 1.003; 1.008), history of stroke (OR 5.06; IC95% 1.04; 18.80) and arterial hypertension (OR 3.15; IC95% 1.38; 7.56). The antibiotic therapy delays not influenced the mortality or re-admission rate. In 24.3% the causative microorganism was identified and antibiotic treatment was inappropriate 19.6%. CONCLUSIONS: Hospital mortality rate was 5.8% and readmission rate was 5.7%. Variables associated with mortality differ from those associated with re-admission. The delay in the antibiotic initiation was not associated with a deleterious effect. Antibiotic therapy was inadequate in almost 20% of patients.

Changes in Left Ventricular Mechanics After Sleeve Gastrectomy.

OBJECTIVE: The aim of this study was to examine echocardiographic parameters of left ventricle (LV) mechanics in obese patients before and after sleeve gastrectomy (SG). DESIGN AND METHODS: Twenty-five obese individuals submitted to laparoscopic SG were enrolled in this study. Echocardiography was performed before and after the procedure, and left ventricle mechanics were evaluated by speckle tracking imaging. RESULTS: Before surgery, altered global longitudinal strain (GLS) values were present in 56% of the patients. In a mean follow-up of 3.6 ± 0.5 months after surgery, there was an increase in GLS values (from 17.4 ± 3.2 to 19.3 ± 2.7%, P = 0.01). There was an inverse correlation between the absolute values of GLS in the preoperative period and the variation in the GLS at follow-up (r = 0.577, P = 0.002). Measurements of global circumferential strain (GCS), global radial strain (GRS), and LV twist were normal preoperatively and did not change after surgery. CONCLUSIONS: Altered global longitudinal strain values were common in young obese patients. Sleeve gastrectomy increased global longitudinal strain even in the early postoperative phase without promoting changes in global radial strain, global circumferential strain, and left ventricle twist measurements.

Epifisiólisis de clavícula medial tipo Salter 1 con desplazamiento posterior agudo en el esqueleto inmaduro / Salter 1 medial collarbone epiphysiolysis with acute posterior displacement in the immature skeleton

Resumen: La epifisiólisis esternoclavicular es una lesión rara, siendo la variante posterior aún menos frecuente. Su presentación clínica puede ser sutil o puede comprometer estructuras mediastinales, ya sea inicialmente o durante la evolución, lo que constituye un cuadro grave y potencialmente fatal. Este reporte de caso documenta una disociación esternoclavicular en un paciente con esqueleto inmaduro, dada por una lesión fisaria tipo Salter y Harris 1, la que se trató quirúrgicamente mediante reducción abierta y fijación interna con lazadas en ocho transóseas con sutura no reabsorbible. Con un seguimiento de 10 meses y resultados excelentes. Esta técnica parece ser una buena opción para el tratamiento de luxación esternoclavicular en el paciente esquemáticamente inmaduro, recuperando la función y evitando complicaciones.

Abstract: Sternoclavicular epiphysiolysis is a rare lesion, the posterior variant being even less common. Its clinical presentation may be subtle, or it may compromise mediastinal structures, either initially or during evolution, which is a serious and potentially fatal picture. This case report documents sternoclavicular dissociation in a patient with an immature skeleton, given by a Salter and Harris 1-type injury, which was surgically treated by open reduction and internal fixation with transosseous configuration with non-reabsorbable suture. With a 10-month follow-up and excellent results. This technique seems to be a good option for the treatment of sternoclavicular dislocation in the schematically immature patient, regaining function and avoiding complications.
