Abstract Objective To identify the frequency of acute kidney injury (AKI) in patients hospitalized with COVID-19, associated characteristics, mortality and lethality. Methods Integrative review carried out in the databases CINAHL, Embase, LILACS, Livivo, PubMed, SCOPUS, Web of Science and in the grey literature (Google Scholar) on January 12, 2022. Articles were included in English, Spanish and Portuguese, published from November 2019 to January 2022, in hospitalized patients over 18 years old with COVID-19 and AKI according to the Kidney Disease Improving Global Outcomes (KDIGO) criteria. The selected studies were read in full for extraction, interpretation, synthesis and categorization according to the level of evidence. Results A total of 699 articles were found and 45 included. Older age, male gender, hypertension, chronic kidney disease, mechanical ventilation, increased C-reactive protein, use of vasoactive drugs and certain classes of antihypertensives were associated with AKI. AKI is related to a higher frequency of mortality. AKI occurred in 30% of patients hospitalized with COVID-19. The mortality rate from AKI was 5% and the case fatality rate was 18%. Conclusion These results highlight the relevance of AKI as a significant complication of COVID-19 and suggest that more careful and early control of associated factors could potentially reduce mortality and lethality. It is crucial to intensify research in this field to better clarify the mechanisms involved in kidney injury in COVID-19 patients, as well as to identify more effective therapeutic strategies for its prevention and treatment in this context.

Cirugía bariátrica y evolución de COVID-19 / Bariatric surgery and evolution of COVID-19

INTRODUCTION. Obesity is recognized as a risk factor for developing severe new coronavirus disease. Bariatric surgery prior to infection could behave as a protective factor against serious infections and death. OBJECTIVE. To describe the impact of bariatric surgery on the severity and mortality of patients with obesity and new coronavirus disease; through a systematic review and meta-analysis of the specialized literature from 2020-2022. METHODOLOGY. Publications indexed in databases such as Pubmed, Tripdatabase, and Google scholar, on the impact of previous bariatric surgery on the evolution and prognosis of patients with new coronavirus disease were taken. The Newcastle-Ottawa scale was used to assess quality and risk of bias. RevMan 5.0 software was used for statistical analysis. RESULTS. Eight cohort studies were included, with a population of 137 620 adult subjects with obesity and new coronavirus disease; of these, 5638 (4.09%) had a history of bariatric surgery. In the meta-analysis, it was determined that, in subjects with obesity and new coronavirus disease, the history of bariatric surgery had a protective effect against the use of mechanical ventilation [OR: 0.68; 95% CI: 0.62-0.75] (p<0.001) and mortality [OR: 0.57; 95% CI: 0.50-0.65] (p<0.01). CONCLUSIONS. The history of bariatric surgery in subjects with obesity seems to have a protective effect against the severity defined by the use of mechanical ventilation in patients with obesity and mortality due to the new coronvirus disease; therefore, the resumption of bariatric surgical activity, at pre-pandemic levels, could represent an additional benefit for candidate subjects.

Trauma severity predictors / Preditores de gravidade no trauma

This review aimed to determine which are the indexes for early detection and evaluation of clinical and physiological deterioration of traumatized patients. A Scoping Review according to the methods proposed by Joanna Briggs Institute (JBI) was performed from February 2018 to December 2018 on LILACS (Literatura Latino-Americana e do Caribe em Ciências da Saúde), National Library of Medicine (PubMed), and SCOPUS databases. Sixty-two studies were included, of which 43 evaluated patients with general trauma. A variety of physiological variables, such as Glasgow Coma Score, Glucose, Days in the Intensive Care Unit, Lactate, and predictor indexes - Injury Severity Score (ISS), Trauma Injury Severity Score (TRISS), Revisited Trauma Score (RTS), and APACHE II were identified. The values observed in the studies among patients were compared to the ones determined by the basic literature, being called Critical Values (CV). The group of gravity indexes, besides clinical and regulatory protocols, found in this review are the solidification of the healthcare process involving the traumatized patient's responses to the actions of the healthcare team. The analysis of these indexes must be emphasized to determine, with greater reliability, the prognosis of the patient. With these data, it may be possible to effectively predict mortality rates (AU).

Conduziu-se uma revisão de escopo de acordo com os métodos propostos pelo Joanna Briggs Institute (JBI) entre fevereiro de 2018 a dezembro de 2018 nas bases de dados LILACS (Literatura Latina-Americana e do Caribe em Ciências da Saúde), National Library of Medicine (PubMed) e SCOPUS. Foram incluídos 62 estudos, dos quais 43 sobre trauma geral. Encontrou-se grande diversidade de variáveis fisiológicas, como Escala de Coma de Glasgow, Glicose, dias em Unidade de Terapia Intensiva, lactato e índices preditores­Injury Severity Score (ISS), Trauma Injury Severity Score (TRISS), Reviseted Trauma Score (RTS) e APACHE II. Os valores observados nos pacientes dos estudos encontrados foram comparados com os da literatura básica, sendo denominados Valores Críticos (CV). O grupo de índices de gravidade encontrados neste estudo, além de protocolos reguladores e clínicos, são a solidificação do processo de cuidado envolvendo a resposta das ações da equipe em saúde ao paciente de trauma. A análise desses índices deve ser enfatizada para determinar com maior confiabilidade o prognóstico do paciente. Com esses dados, pode ser possível predizer a taxa de mortalidade com maior acurácia (AU).

Correlation between macrophage chemotaxis and disease severity in patients with knee osteoarthritis / 中国骨伤

OBJECTIVE@#To investigate the enhancement of macrophage chemotaxis in patients with knee osteoarthritis (KOA) and its correlation with the disease severity.@*METHODS@#Eighty patients with KOA admitted from July 2019 to June 2022 were enrolled as the observation group and divided into 29 cases of moderate group, 30 cases of severe group and 21 cases of extremely severe group. At the same time, 30 healthy subjects were included as the control group. The gene expressions of NF-κB, CXC chemokine receptor 7 (CXCR7) and CXC chemokine ligand 12 (CXCL12) in macrophages of each group were analyzed. Visual analogue scale(VAS) was used to evaluate the degree of joint pain. Joint function was evaluated by knee Joint Society Scoring system(KSS). Finally, data analysis was carried out.@*RESULTS@#The expression levels of NF-κB, CXCR7 and CXCL12 in moderate group, severe group and extreme recombination group were higher than those in control group. The VAS, the expression of NF-κB, CXCR7 and CXCL12 in the severe group and the extreme recombination group were higher than those in the moderate group, whereas KSS was lower than that in the moderate group. The VAS, expression levels of NF-κB, CXCR7 and CXCL12 in the extremely severe group were higher than those in the severe group, and KSS was lower than that in the severe group (all P<0.01). The expression levels of NF-κB, CXCR7 and CXCL12 in macrophages were positively correlated with VAS score, but negatively correlated with KSS(all P<0.01). The expression levels of NF-κB, CXCR7 and CXCL12 in macrophages were positively correlated with the severity of disease. After excluding the influence of traditional factors (gender, age and disease duration), multiple linear regression analysis further showed that the expression levels of NF-κB, CXCR7 and CXCL12 were still positively correlated with the severity of disease(all P<0.01).@*CONCLUSION@#The chemotaxis of macrophages in patients with KOA increased with the aggravation of the disease, and was related to the degree of pain and function impairment.

Haematological indices and coagulation profile as predictors of disease severity and associations with clinical outcome among COVID­19 patients in Lagos, Nigeria

Background: This study aims to evaluate the use of haematological indices and coagulation profiles as possible low cost predictors of disease severity and their associations with clinical outcomes in COVID 19 hospitalized patients in Nigeria. Materials and Methods: We carried out a hospital based descriptive 3 month observational longitudinal study of 58 COVID 19 positive adult patients admitted at the Lagos University Teaching Hospital, Lagos, Nigeria. We used a structured questionnaire to obtain the participants' relevant sociodemographic and clinical data, including disease severity. Basic haematologic indices, their derivatives, and coagulation profile were obtained from patients' blood samples. Receiver Operating Characteristic (ROC) analysis was used to compare these laboratory based values with disease severity. A P < 0.05 was considered statistically significant. Results: The mean age of the patients was 54.4 ± 14.8 years. More than half of the participants were males (55.2%, n = 32) and most had at least one comorbidity (79.3%, n = 46). Significantly higher absolute neutrophil count (ANC), neutrophil­lymphocyte ratio (NLR), systemic immune inflammation index (SII), lower absolute lymphocyte count (ALC) and lymphocyte­monocyte ratio (LMR) were associated with severe disease (P< 0.05). Patients' hemoglobin concentration (P= 0.04), packed cell volume (P< 0.001), and mean cell hemoglobin concentration (P= 0.03) were also significantly associated with outcome. Receiver operating characteristic (ROC) analysis of disease severity was significant for the ANC, ALC, NLR, LMR, and SII. The coagulation profile did not show any significant associations with disease severity and outcomes in this study. Conclusion: Our findings identified haematological indices as possible low cost predictors of disease severity in COVID 19 in Nigeria

Anomalies électrocardiographiques chez les patients hospitalisés pour COVID-19 à Fianarantsoa, Madagascar

Les anomalies électrocardiographiques sont l'expression d'une atteinte cardiovasculaire lors de la COVID-19. Les troubles du rythme et de la conduction cardiaque peuvent mettre en jeu le pronostic vital à court terme au cours de la COVID -19. Notre objectif principal est de décrire les anomalies électrocardiographiques et leurs fréquences chez les patients atteints de la COVID -19. L'objectif secondaire est de déterminer l'association entre ces anomalies électrocardiographiques et la gravité de la maladie. Méthodes : Il s'agit d'une étude rétrospective à visée descriptive des patients hospitalisés pour COVID-19 dans les centres de traitement COVID -19 de Fianarantsoa sur une période de 14 mois. Résultats : Nous avons retenu 101 patients. Le sex-ratio était de 1,06. La moyenne d'âge était de 59,81ans +/- 11,9. Tous les patients retenus avaient un électrocardiogramme à 12 dérivations et un test positif à la COVID-19. L'électrocardiogramme (ECG) était anormal chez 87 (86,1%) patients. Dans les formes graves et modérées de la maladie nous avons enregistré à l'ECG: 51 (50,5%) tachycardies sinusales, 13 (12,8%) blocs de branche incomplets droits, 13 (12,8%) profil S1Q3T3, 24 (23,7%) ondes Q pathologiques, 19 (18,8%) anomalies du segment ST. Dans les formes graves de la maladie nous avons enregistré à l'ECG: 2 (3,8%) bloc auriculoventriculaire complet (BAV complet), 7 (13,4%) blocs de branche gauche complet (BBG), 5 (9,6%) blocs de branche droit complet (BBD). La tachycardie sinusale avait une association significative avec la gravité de la maladie (p=0,002). Conclusion : Des anomalies électrocardiographiques ont été observées dans notre étude. La tachycardie sinusale était associée à la gravité de la maladie. Une surveillance rythmique, des explorations cardiaques plus pertinentes sont nécessaires pour une meilleure prise charge de la COVID-19

Técnica de Seldinger® modificada para inserção de catéter central de inserção periférica / Modified Seldinger® technique for peripherally inserted central catheter insertion

Resumo: Os recém-nascidos durante o período de internação em unidade de terapia intensiva neonatal necessitam de cateterismo percutâneo no tratamento devido à gravidade clínica apresentada e à terapia de infusão necessária para a restauração das funções vitais. Na Unidade de Terapia Intensiva Neonatal, essa tecnologia é a primeira escolha quando o paciente necessita de acesso venoso a partir de 7 dias, já que o procedimento pode ser realizado à beira leito, por enfermeiros capacitados e dispensa anestesia geral. Com o tempo, o procedimento de inserção do dispositivo vascular passou por refinamentos. A tecnologia de Seldinger modificada foi uma das inovações incrementais. Entretanto, no contexto público no qual o hospital se encaixa, a incorporação de novas tecnologias é tardia e, portanto, os enfermeiros permaneciam utilizando a tecnologia convencional para cateterismo percutâneo. Assim, o estudo desenvolvido agregou novas funcionalidades e características à terapia de infusão de neonatos criticamente enfermos, resultando em ganho efetivo de qualidade no cuidado e segurança, sem alterar as funções e finalidades já existentes da tecnologia em vigor. Objetivo: implementar o uso da tecnologia de Seldinger modificada para a inserção de cateterismo percutâneo em recém-nascidos criticamente enfermos. Método: estudo quase experimental. A intervenção realizada foi a capacitação por meio da avaliação pré e pós-teste, realizada em hospital de referência. Participaram da pesquisa 48 profissionais de enfermagem (enfermeiros e técnicos). A intervenção educativa foi avaliada por meio de instrumento aplicado anteriormente para analisar os conhecimentos prévios sobre a temática, e na sequência houve o pós-teste. O instrumento de avaliação da intervenção para os enfermeiros caracterizou-se por conter 37 questões relacionadas à pré-inserção, à inserção e à manutenção do dispositivo vascular. Para os técnicos de enfermagem, o instrumento de avaliação continha 20 questões sobre os cuidados relacionados ao cateter. Foi realizada análise descritiva dos dados por técnicas estatísticas adequadas. Resultados: Para ambos os grupos, houve maior número de acertos no pós-teste do que no pré-teste. Os enfermeiros demostraram confiabilidade na inserção e manutenção do dispositivo. Na avaliação das inserções executadas por enfermeiros, através da observação direta, verificou-se melhora na realização da segunda inserção do cateter pela nova tecnologia em comparação com a primeira. Os técnicos obtiveram maior acerto nos cuidados após a capacitação. Conclusão: o processo de incorporação da tecnologia na unidade de terapia intensiva neonatal foi satisfatório. A capacitação evidenciou que os profissionais de saúde necessitam de educação continuada e permanente, e resultou em aumento do conhecimento dos profissionais de enfermagem sobre a tecnologia de Seldinger modificada.

Abstract: Newborns during their stay in a neonatal intensive care unit need percutaneous catheterization for treatment due to the clinical severity presented and the infusion therapy required to restore vital functions. In the Neonatal Intensive Care Unit, this technology is the first choice when the patient needs venous access from 7 days since the procedure can be performed at the bedside by trained nurses and does not require general anesthesia. Over time, the vascular device insertion procedure has undergone refinements. The modified Seldinger technology was one of the incremental innovations. However, in the public context in which the hospital is located, the incorporation of new technologies is late and, therefore, nurses continued to use conventional technology for percutaneous catheterization. Thus, the study developed added new functionalities and features to infusion therapy for critically ill neonates, resulting in an effective gain in quality of care and safety, without changing the existing functions and purposes of the technology in force. Objective: to implement the use of modified Seldinger technology for percutaneous catheterization insertion in critically ill newborns. Method: quasi-experimental study. The intervention was training through pre- and post-test evaluation, carried out in a reference hospital. Forty-eight nursing professionals (nurses and technicians) participated in the research. The educational intervention was evaluated by means of a previously applied instrument to analyze the previous knowledge about the theme, and then there was the post-test. The instrument to evaluate the intervention for nurses contained 37 questions related to pre-insertion, insertion, and maintenance of the vascular device. For the nursing technicians, the evaluation instrument contained 20 questions about catheter-related care. Descriptive data analysis was performed using appropriate statistical techniques. Results: For both groups, there were more correct answers in the post-test than in the pre-test. The nurses showed reliability in device insertion and maintenance. In the evaluation of the insertions performed by nurses, through direct observation, there was an improvement in the second catheter insertion using the new technology when compared to the first. The technicians were more accurate in their care after the training. Conclusion: the process of incorporating the technology in the neonatal intensive care unit was satisfactory. The training showed that health professionals need continued and permanent education and resulted in increased knowledge of nursing professionals about the modified Seldinger technology.

Administración de fluidos a pacientes graves y su relación con la mortalidad / Fluids administration to seriously ill patients and its relationship with mortality

Introducción: La administración de fluidos constituye uno de los pilares de tratamiento en pacientes que ingresan en Unidades de Cuidados Intensivos, en quienes la reanimación inadecuada y la sobrecarga de volumen empeoran el pronóstico. Objetivo: Caracterizar el estado de la administración de fluidos a pacientes ingresados en la Unidad de Cuidados Intensivos del Hospital General Docente Dr. Antonio Luaces Iraola de Ciego de Ávila y su relación con la mortalidad. Métodos: Se realizó un estudio descriptivo analítico y prospectivo de 147 pacientes ingresados en la Unidad de Cuidados Intensivos del Hospital General Docente Dr. Antonio Luaces Iraola de Ciego de Ávila durante el primer semestre de 2020, para lo cual se evaluaron 598 pruebas de fluidos, algunas variables hemodinámicas y el balance de líquidos en las primeras 72 horas del ingreso. Resultados: El promedio de edad fue de 48,3 años, predominaron las mujeres (55,8 %), la puntuación de APACHE II al ingreso resultó ser de 14,2 puntos y fallecieron 22,4 % de los afectados. Para administrar fluidos prevaleció el criterio clínico (57,2%); mientras que la presión venosa central, la frecuencia cardíaca, la presión arterial media y la diuresis fueron similares en vivos y fallecidos. El balance acumulado de fluidos fue significativamente superior en el grupo de pacientes fallecidos (1984,70 mL vs 260mL). Conclusiones: Los cambios en los parámetros vitales después de administrar fluidos no fueron útiles para evaluar la respuesta al volumen. El balance acumulado de fluidos se relacionó de forma significativa con la mortalidad.

Introduction: Fluids administration constitutes one of the treatment pillars in patients admitted to Intensive Care Unit in which the inadequate reanimation and overload of volume worsen the prognosis. Objective: To characterize the state of fluid administration to patients admitted to the Intensive Cares Units of Dr. Antonio Luaces Iraola Teaching General Hospital in Ciego de Ávila and its relationship with mortality. Methods: An analytic and prospective descriptive study of 147 patients admitted to the Intensive Cares Units of Dr. Antonio Luaces Iraola Teaching General Hospital was carried out in Ciego de Ávila during the first semester of 2020, for which 598 tests of fluids, some hemodynamic variables and the balance of liquids were evaluated in the first 72 hours of admission. Results: The average age was 48.3 years, there was a prevalence of women (55.8 %), the punctuation of APACHE II at admission was 14.2 points and 22.4 % of those affected died. To administer fluids the clinical approach prevailed (57.2 %); while the central venous pressure, heart frequency, the mean arterial pressure and diuresis were similar in alive and dead patients. The accumulated balance of fluids was significantly higher in the group of dead patients (1984.70 mL vs 260 mL). Conclusions: The changes in the vital parameters after administering fluids were not useful to evaluate the response to the volume. The accumulated balance of fluids was related to mortality in a significant way.

Evaluation of Knowledge, Disease Severity and Quality of Life of Patients with Psoriasis

Background@#Psoriasis vulgaris is a chronic immune-mediated inflammatory multi-system disease characterised by keratinocyte hyperproliferation. Data regarding patients’ disease severity, knowledge and quality of life (QOL) is important to optimize treatment strategies for psoriasis. This study aims to evaluate and investigate the relationship between disease severity, knowledge and QOL of patients with psoriasis. @*Methods@#A cross-sectional multicentre study utilizing a socio-demographic data collection form, Psoriasis Knowledge Assessment Questionnaire (PKAQ), Dermatology Life Quality Index (DLQI) and Psoriasis Area and Severity Index (PASI was conducted. Correlations between PKAQ, DLQI and PASI were analysed using Spearman’s test. @*Results@#A total of 114 subjects participated in this study. Majority of them had mild psoriasis (n=73, 64%) based on PASI. The mean score of PKAQ was fourteen out of a total possible score of twenty-five, whereas the DLQI had a non-parametric distribution with a median (interquartile range) of 7 (10). Most subjects (32.5%) stated that psoriasis had a ‘moderate effect’ on their QOL, while only 3.5% said that it had an ‘extremely large effect’ on their QOL. There was a statistically significant correlation between PASI and DLQI (rs = 0.264, p = 0.004), with higher PASI scores corresponding to higher DLQI scores. No statistically significant correlation was found between DLQI and PKAQ (rs = -0.048, p= 0.612), and between PASI and PKAQ (rs = 0.058, p= 0.542).@*Conclusion@#Impairment of QOL was positively associated with severity of psoriasis. However, there was no significant relationship between knowledge and quality of life, as well as between knowledge and psoriasis severity.

Relação do risco nutricional e perfil glicêmico no desfecho de pacientes críticos / Relationship of nutritional risk and glycemic profile in the outcome of critically ill patients

Em pacientes críticos o risco nutricional e a hiperglicemia associam-se ao aumento da incidência de desfechos desfavoráveis. Objetivo: Avaliar a relação do risco nutricional pelo Nutrition Risk in Critically III, versão modificada (mNUTRIC) e perfil glicêmico nos desfechos de alta, óbito e tempo de internação de pacientes críticos e verificar o impacto das ferramentas Acute Physiology and Chronic Health Disease Classification System II (APACHE II) e do Sepsis-Related Organ Failure Assessment (SOFA) nesses desfechos. Método: Estudo longitudinal prospectivo desenvolvido em Unidade de Terapia Intensiva (UTI). Foram incluídos adultos, com tempo ≥ 48 horas de internação e com registro mínimo de duas aferições glicêmicas. Excluíram-se pacientes em cuidados paliativos, readmitidos nas UTI e gestantes. O teste Exato de Fisher e Shapiro Wilk foram utilizados para avaliar as variáveis categóricas e contínuas, respectivamente. Posteriormente, utilizou-se o teste de Mann-Whitney ou t-Student não pareado. Realizou-se análise de regressão logística e linear. O nível de significância adotado foi de 5%. Resultados: Ao avaliar 35 pacientes, 45,7% apresentaram alto risco nutricional. Foi observado associação do risco nutricional com os desfechos de alta e óbito; o SOFA associou-se ao óbito e tempo de internação. O incremento de 1 ponto no escore do SOFA aumentou a chance de óbito em 83% e tempo maior de internação em 0,49 dias. O perfil glicêmico e APACHE II não se associou aos desfechos. Conclusão: o escore SOFA foi o instrumento que apresentou associações significativas com o desfecho do óbito e maior tempo de internação de pacientes críticos

In critically ill patients, nutritional risk and hyperglycemia are associated with an increased incidence of unfavorable outcomes. Objective: To evaluate the relationship of nutritional risk by the Nutrition Risk in Critically III, modified version (mNUTRIC) and glycemic profile in the outcomes of discharge, death and length of stay in critically ill patients and to verify the impact of the Acute Physiology and Chronic Health Disease Classification System II (APACHE II) and the Sepsis-Related Organ Failure Assessment (SOFA) tools on these outcomes. Method: Prospective longitudinal study developed in an Intensive Care Unit (ICU). Adults were included, with ≥ 48 hours of hospitalization and with a minimum record of two blood glucose measurements. Patients in palliative care, readmitted to ICU and pregnant women were excluded. Fisher's Exact test and Shapiro Wilk test were used to evaluate categorical and continuous variables, respectively. Subsequently, the Mann-Whitney or unpaired t-Student test was used. Logistic and linear regression analysis was performed. The significance level adopted was 5%. Results: When evaluating 35 patients, 45.7% were at high nutritional risk. An association was observed between nutritional risk and discharge and death outcomes; SOFA was associated with death and length of hospital stay. The increment of 1 point in the SOFA score increased the chance of death by 83% and a longer hospital stay by 0.49 days. Glycemic profile and APACHE II were not associated with outcomes. Conclusion: the SOFA score was the instrument that showed significant associations with the outcome of death and longer hospital stay in critically ill patients

LA ADAPTACIÓN DE LA HEMOGLOBINA Y LOS GLOBULOS BLANCOS EN CASOS SEVEROS DE SARS-COV-2 / THE ADAPTATION OF HEMOGLOBIN AND WHITE BLOOD CELLS IN SEVERE CASES OF SARS-COV-2

Dado que el SARS-CoV-2 causa alteraciones en los parámetros hematológicos, muchos estudios se han concentrado en esta área y los han correlacionado con la gravedad de la enfermedad. Se revisó en un estudio retrospectivo de casos graves de COVID-19, en el cual se contabilizaron y documentaron los datos de hemoglobina (Hb) y glóbulos blancos (WBC) de pacientes reclutados en el período de marzo a julio de 2021. Retrospectivamente, los datos extraídos fueron sobre el nivel de Hb y los recuentos de glóbulos blancos de los informes de laboratorio tanto al ingreso como cuando alta de los pacientes. Se calcularon las frecuencias de anemia o eritrocitopenia (Hb <12 g/dL) y leucocitosis (WBC >11×103/µL) en la población estudiada. De 3637 casos de SARS-COV-2, 250 pacientes con condiciones graves de COVID-19 según la definición de la OMS, ingresaron en la UCI o fallecieron, De 250, 80 (32%) ingresaron a UCI, y el resto 170 casos (68%) fallecieron. Mientras que la edad media de los pacientes fue de 55,46±17,49 años, los pacientes con la condición grave tuvieron significativamente mayor edad que aquellos con la condición leve-moderada (edad media de 50,68 frente a 68,59; P: <0,01). El número medio de glóbulos blancos (WBC) fue de 8,88±7,29 x109/L en todos los pacientes con SARS-COV-2, que es significativamente mayor en los casos graves en comparación con aquellos con enfermedad leve-moderada (10,56 frente a 8,95; P: <0,01). El nivel de Hb (<12 g/dL) fue más bajo en el COVID-19 grave que en otros grupos; sin embargo, no fue estadísticamente significativo. El aumento del número de glóbulos blancos y la disminución de la Hb durante la hospitalización de pacientes con SARS-COV-2, puede predecir un mal resultado. Llegamos a la conclusión de que no sólo el número medio de glóbulos blancos era significativamente mayor en los casos severos también la leucocitosis fue un hallazgo común; lo que indica que un mayor número de glóbulos blancos probablemente puede predecir un mal resultado. Asimismo, el nivel de La Hb fue mayor en el grupo leve-moderado; sin embargo, no fue estadísticamente significativo.

SARS-CoV-2 cause alterations in the hematological parameters and many studies have concentrated on this area and correlated these with severity of disease. A retrospective study of severe cases of COVID-19 were reviewed. The data of hemoglobin (Hb) and white blood cells (WBCs) were accounted and documented. Patients recruited at period from March to July, 2021. Retrospectively, data extracted on the Hb level and WBC counts from Lab reports both at admission and when patients discharge. The frequencies of anemia or erythrocytopenia (Hb <12 g/dL) and leukocytosis (WBC >11×103/µL) was calculated in the studied population. Of 3637 SARS-COV-2 cases, 250 patients with severe conditions of COVID-19 as de ne by WHO, which were either admitted to ICU or died. Of 250, 80(32%) were entered to ICU, and the rest 170 cases (68%) who died. While the mean age of the patients was 55.46±17.49 years, patients with the severe condition were signi cantly older than those with the mildmoderate condition (mean age of 50.68 vs. 68.59; P: <0.01). The mean number of white blood cells (WBC) was 8.88±7.29 x109/L in all SARS-COV-2 patients, which is signi cantly higher in the severe cases compared to those with the mild-moderate disease (10.56 vs. 8.95; P: <0.01). The Hb level (<12 g/ dL) was lower in the severe COVID-19 than other groups; however, it was not statistically signi cant. Increased number of WBCs and dropped Hb level during hospitalization of SARS-COV-2 patients may predict a poor outcome. We concluded that not only the mean number of WBCs was signi cantly higher in the severe cases also leukocytosis was a common nding; indicating that an increased number of WBCs may probably predict a poor outcome. Also, the level of Hb was higher in the mild-moderate group; however, it was not statistically signi cant.

Evaluación de gravedad en pacientes agudos / Evaluation of severity in acute patients

Severity meaning the risk of adverse outcomes, death or disability, varies along disease's characteristics and patient related factors. Its evaluation is complex and besides subjective perception several, more objective, clinical tools exist along with laboratory data that independently or used in combination, allows the clinician to approach severity of a given patient's condition or a particular disease. We will review several aspects of the evaluation of severity, clinical and laboratory based in addition of some scoring systems, emphasizing perfusion and organ dysfunction evaluation as key elements to assess severity particularly in critical situations.

Características de la mortalidad por tumores malignos en la provincia de Matanzas. 1990-2019 / Characteristics of mortality due to malignant tumors in the province of Matanzas. 1990-2019

RESUMEN Introducción: la mortalidad por tumores malignos se caracteriza por un incremento sostenido en el tiempo. En casi la totalidad de la provincia de Matanzas se ha observado esta tendencia en los últimos 30 años, con mayor o menor intensidad. Objetivo : describir algunas características de la mortalidad por cáncer en la provincia de Matanzas. Materiales y métodos: estudio observacional descriptivo retrospectivo de la mortalidad por tumores malignos durante 30 años (1990-2019). Se estimaron tasas crudas y ajustadas de mortalidad, globalmente, por períodos y por sexo. Se obtuvieron porcentajes y se determinó la significación estadística mediante el estadígrafo X2 y el valor de p < 0,05. Resultados: se detectaron diferencias estadísticas significativas entre sexos en cada uno de los períodos. Las tasas crudas y específicas de mortalidad experimentaron una tendencia sostenida al incremento. Cada 0,3 días (aproximadamente cada 8 horas) ocurrió una defunción por cáncer, con diferencias entre las localizaciones. Conclusiones: la tendencia al incremento sostenido de las tasas de mortalidad cruda y ajustada por edad se debe al aumento de las defunciones, pudiendo ser consecuencia, en parte, del envejecimiento poblacional y de un posible incremento de la morbilidad. El sexo masculino apareció como el más expuesto. La frecuencia de la mortalidad por cáncer fue diferente según localizaciones (AU).

ABSCRACT Introduction: Steady increase in time characterized the mortality by malignant tumors in the world as in Cuba. It was observed similar trend in the province of Matanzas in the last 30 years, almost in all body sites, showing higher or less intensity. Objective: To describe some characteristics of mortality by malignant tumors in the province of Matanzas Materials and methods: It is a descriptive observational and retrospective study of the mortality by malignant tumors for 30 years: 1990-2019. Crude and adjusted mortality rates were estimated, globally, by periods and sex. Percentages were estimated and statistical significance was determined through X2 test and p value < 0,05. Results: Statistical significant differences were detected among sexes in all periods. Crude and specific mortality rates showed an increasing steady trend. Every 0.3 days (around 8 hours) one decease took place due to malignant tumors, with differences among sites of the disease. Conclusions: The increasing steady trend of the crude & adjusted mortality rates by age could be, partly, results of the population ageing. Male sex appeared to be the most exposed. Mortality frequency by malignant tumors was different according to sites of the tumor (AU).

Modos ventilatorios usados en pacientes críticos con covid-19 en la región de Lombardía, Italia / Ventilation modes used in critical patient with COVID-19 in the region of Lombardy, Italy

RESUMEN Introducción: la covid-19 es una enfermedad donde la ventilación mecánica artificial cobra vital importancia. Se estima que el 50 % de los casos graves o críticos que requieren manejo en unidades de cuidados intensivos fallecen. Objetivos: se evaluó el impacto de los modos ventilatorios usados en pacientes con covid-19 en Lombardía, Italia, en la oxigenación, la hemodinámica y la mortalidad. Materiales y métodos: se realizó un estudio analítico longitudinal retrospectivo en 86 pacientes críticos con covid-19, en el Hospital Mayor de Crema, en Lombardía, Italia, desde el 1 de abril al 20 de mayo de 2020. Se realizaron análisis no paramétrico y de la varianza. Resultados: Hubo una supervivencia del 76,7 %. El modo utilizado tuvo igual comportamiento en occisos (BiPAP-3, PCV-4, VCRP-4, APRV-5, VCV-4) y en vivos (BiPAP-10, PCV-17, VCRP-14, APRV-15, VCV-10); test de x2 = 0,59; test de análisis de la varianza media índice PO2/FIO2 (PCV = 132), (BiPAP = 132) (VCV = 115) p = 0,924. La presión de final de espiración positiva (BiPAP-12, PCV-13, VCRP-13, APRV-13, VCV-14) con p = 0,205. PCO2 (BiPAP-55, PCV-52, VCRP-57, APRV-59, VCV-57) con p = 0,512. La tensión arterial media (BiPAP-84, PCV-83, VCRP-84, APRV-82, VCV-83) con p = 0,988. Modelos de cálculo de la presión de final de espiración positiva, según modo ventilatorio: BiPAP: PEEP = -0,0331 (índice PO2/FiO2) +18,215; PCV: PEEP = -0,0047 (índice PO2/FiO2) +13,717; VCRP: PEEP = -0,0204 (índice PO2/FiO2) +15,678; APRV: PEEP = -0,0092 (índice PO2/FiO2) +14,889. Conclusiones: la evolución del paciente crítico con covid-19 está determinada en gran medida por la ventilación mecánica invasiva; sin embargo, no existió suficiente evidencia para recomendar una u otra modalidad ventilatoria. El éxito está en conocer con exactitud las características del respirador, su modalidad y el paciente en cuestión. (AU)

ABSTRACT Introduction: COVID-19 is a disease in which mechanical ventilation acquires vital importance. It is estimated that 50 % of the serious and critical patients requiring management in intensive care units die. Objectives: to assess the impact of the ventilation modes used in patients with COVID-19 in Lombardy, Italy, on oxygenation, hemodynamics and mortality. Materials and methods: a retrospective, longitudinal, analytic study was carried out in 86 critical patients with COVID-19 who entered the Main Hospital of Crema, in Lombardy, Italy, from April 1st to May 20, 2020. Results: the survival was 76.7 %. The used mode showed the same behavior in deceased patients (BiPAP-3, PCV-4, VCRP-4, APRV-5, VCV-4) and in alive patients (BiPAP-10, PCV-17, VCRP-14, APRV-15, VCV-10). X2 = 0.59. ANOVA test index PO2/FIO2 (PCV = 132), (BiPAP = 132) (VCV=115) p = 0.924. PEEP (BiPAP-12, PCV-13, VCRP-13, APRV-13, VCV-14) p = 0.205. PCO2 (BiPAP-55, PCV-52, VCRP-57, APRV-59, VCV-57) p = 0.512. Average blood pressure (BiPAP-84, PCV-83, VCRP-84, APRV-82, VCV-83) p = 0.988. PEEP models according to ventilation mode: BiPAP: PEEP = -0.0331 (PO2/FiO2 index) +18.215. PCV: PEEP = -0.0047 (PO2/FiO2 index) + 13.717; VCRP: PEEP = -0.0204 (PO2/FiO2 index) + 15.678; APRV: PEEP = -0.0092 (PO2/FiO2 index) +14.889. Conclusion: the evolution of the critical patient with COVID-19 is determined mostly by the invasive mechanical ventilation; but we did not find evidence enough to recommend one or the other ventilation mode. The success stands in knowing accurately the characteristics of the ventilator, the ventilation modes and the patient (AU).

Correlación de índice PO2/FiO2 con parámetros inflamatorios y de coagulación en pacientes críticos con covid-19. Lombardía, 2020 / PO2/FiO2 index correlation with inflammatory and coagulation parameters in critically-ill patients with COVID-19 in Lombardy, 2020

RESUMEN Introducción: el conocimiento de la fisiopatología de la enfermedad ha revolucionado el enfoque tradicional en el tratamiento de las enfermedades causadas por virus respiratorios. Actualmente, se utilizan marcadores de la respuesta inflamatoria para diagnosticar, estratificar y predecir en muchos casos el comportamiento futuro del enfermo de covid-19. Objetivo: caracterizar la naturaleza de la relación entre el índice PO2/FiO2 y los parámetros inflamatorios y de coagulación en pacientes graves por la covid-19, en la región de Lombardía, Italia. Materiales y métodos: se realizó un estudio analítico, longitudinal, retrospectivo con 191 pacientes graves y críticos, que ingresaron con diagnóstico de covid-19 del 1 de abril al 20 mayo de 2020, en el Hospital Mayor de Crema, en la región de Lombardía, Italia. Resultados: las correlaciones evidenciadas fueron las siguientes: proteína C reactiva (-0,417) p = 0; procalcitonina (-0,152) p = 0,018; dímero D (-0,112) p = 0,061; fibrinógeno (-0,272) p = 0,000; creatinina plasmática (-0,320) p = 0,000; conteo de linfocitos (0,028) p = 0,000; troponina (-0,028) p = 0,142, y lactato (-0,191) p = 0,288. Conclusiones: los marcadores inflamatorios en la patogenia de la enfermedad juegan un rol capital, y el enfoque hacia este renglón del tratamiento médico antiinflamatorio de cualquier tipo es mandatorio. Se debe realizar un correcto monitoreo de la coagulación, usar heparinas de bajo peso molecular, así como mantener un adecuado soporte hemodinámico capaz de evitar las disoxias celulares que progresen al fallo multiorgánico (AU).

ABSTRACT Introduction: the knowledge of disease physiopathology has revolutionized the traditional approach in the treatment of diseases caused by respiratory viruses. Currently, the markers of inflammatory answer are used to diagnose, stratify and predict in many cases the future behavior of COVID-19 patients. Objective: to characterize the nature of the relationship between PO2/FiO2 (PAFI, Spanish acronym of PA= presión arterial [arterial pressure], FI=fracción inspirada [inspired fraction]) and coagulation and inflammatory parameters in seriously-ill patients with COVID-19, in the region of Lombardy, Italy. Materials and methods: a retrospective, longitudinal, analytic study was carried out in 191 severe and critical patients who were admitted in Hospadale Maggiori di Crema, in the region of Lombardy, Italy, with the diagnosis of COVID-19, in the period April 1st-May 20, 2020. Results: the evidenced correlations were the following: reactive C protein (-0.417) p=0; procalcitonin (PCT) (-0.152) p=0.018. D dimer (-0.112) p=0.061; Fibrinogen (-0.272) p=0.000; Plasma creatinine (-0.320) p=0.000; lymphocytes count (0,028) p=0,000; troponin (-0.028) p=0.142; and lactate (-0.191) p=0.288. Conclusions: inflammatory markers play a capital role in the disease pathogenesis, and approaching this item of the medical anti-inflammatory treatment is mandatory. It is useful to keep a correct coagulation screening, using low molecular weight heparins, and also keeping an adequate hemodynamic support able to avoid cell dysoxia progressing to multiorgan failure (AU).
