The stability of cardiometabolic risk factors clustering in children and adolescents: a 2-year longitudinal study.

Objective: The present study aims to verify the odds of remaining with the clustering of 3 or more, 4 or more, and 5 or more risk factors across a 2-year time span. Methods: Observational longitudinal study that included 358 children and adolescents (10.96 ± 2.28 years of age at baseline). Cardiorespiratory fitness, glucose, systolic blood pressure, total cholesterol/high-density lipoprotein cholesterol ratio, triglycerides, and waist circumference were assessed. The number of children in whom the risk factors were not independently distributed was analyzed. Odds ratios of presenting n risk factors clustered at follow-up according to the number of risk factors observed at baseline were calculated. Results: More participants than expected were found presenting clustering of 4 or more and 5 or more risk factors at both baseline (11.7% and 5.6%, respectively) and follow-up (9.5% and 5.6%, respectively). The odds ratios calculated demonstrated that the odds of presenting the same number of risk factors clustered or more at follow-up increased according to the number of risk factors clustered at baseline. Conclusion: The higher the number of risk factors a child had at baseline, the higher the odds of presenting the same number of risk factors or more after two years of follow-up.

Incidence of Arterial Hypertension is Associated with Adiposity in Children and Adolescents. / Incidência de Hipertensão Arterial está Associada com Adiposidade em Crianças e Adolescentes.

BACKGROUND: The increase of hypertension in children and adolescents has attracted the attention of the scientific community largely due to its association with the obesity epidemic. OBJECTIVES: To describe the incidence of hypertension and its relationship with the cardiometabolic and genetic profile in children and adolescents from a city in southern Brazil in a three-year period. METHODS: This longitudinal study followed 469 children and adolescents, aged 7-17 years old (43.1% boys), assessed at two-time points. We evaluated systolic and diastolic blood pressures (SBP and DBP), waist circumference (WC), body mass index (BMI), body fat percentage (%BF), lipid profile, glucose, cardiorespiratory fitness (CRF), and rs9939609 Polymorphism ( FTO ). Cumulative incidence of hypertension was calculated, and multinomial logistic regression was conducted. The statistical significance was established as p < 0.05. RESULTS: After three years, the incidence of hypertension was 11.5%. Overweight or obese individuals were more likely to become borderline hypertensive (overweight OR: 3.22, 95% CI: 1.08-9.55; obesity OR: 4.05, 95% CI: 1.68-9.75), and obese individuals were more likely to become hypertensive (obesity OR: 4.84, 95% CI: 1.57-14.95). High-risk WC and %BF values were associated with hypertension development (OR: 3.41, 95% CI: 1.26-9.19; OR: 2.49, 95% CI: 1.08-5.75, respectively). CONCLUSIONS: We found a higher incidence of hypertension in children and adolescents as compared with previous studies. Individuals with higher values of BMI, WC and %BF at baseline were more likely to develop hypertension, suggesting the importance of adiposity in the development of hypertension even in such a young population.

FUNDAMENTO: O aumento de hipertensão em crianças e adolescentes tem atraído a atenção da comunidade científica, especialmente por sua associação com a epidemia da obesidade. OBJETIVOS: Descrever a incidência de hipertensão e sua relação com o perfil cardiometabólico e genético em crianças e adolescentes de uma cidade do sul do Brasil em um período de três anos. MÉTODOS: Este estudo longitudinal acompanhou 469 crianças e adolescentes com idade entre 7 e 17 anos (43,1% do sexo masculino), avaliados em dois momentos. Avaliamos pressão arterial sistólica (PAS), pressão arterial diastólica (PAD), circunferência da cintura (CC), índice de massa corporal (IMC), porcentagem de gordura corporal (%GC), perfil lipídico, glicemia, aptidão cardiorrespiratória (APCR), e polimorfismo rs9939609 (gene FTO ) ( fat mass and obesity - associated gene ). A incidência cumulativa da hipertensão foi calculada, e realizada regressão logística multinominal. A diferença estatística foi estabelecida em p<0,05. RESULTADOS: Após três anos, a incidência de hipertensão foi de 11,5%. Indivíduos com sobrepeso e indivíduos obesos apresentaram maior probabilidade de se tornarem indivíduos classificados como borderline para hipertensão (sobrepeso OR: 3,22; IC95%: 1,08-9,55; obesidade OR: 4,05; IC95%: 1,68-9,75), e indivíduos obesos apresentaram maior probabilidade de se tornarem hipertensos (obesidade OR: 4,84; IC95%: 1,57-14,95). Valores de CC e de %GC considerados de alto risco foram associados com o desenvolvimento de hipertensão (OR: 3,41; IC95%: 126-9,19; OR: 2,49, IC95%: 1,08-5,75, respectivamente). CONCLUSÃO: Encontramos uma incidência de hipertensão em crianças e adolescentes mais alta em comparação a estudos anteriores. Indivíduos com valores mais altos de IMC, CC e %GC no baseline apresentaram maior probabilidade de desenvolverem hipertensão, sugerindo a importância da adiposidade no desenvolvimento de hipertensão, mesmo em uma população tão jovem.

The triglyceride-glucose index as an indicator of insulin resistance and cardiometabolic risk in Brazilian adolescents.

Objective: To set cutoff points for the triglyceride and glucose index (TyG) as a marker of insulin resistance (IR) for the pediatric population. Subjects and methods: This was a cross-sectional study with schoolchildren population-based data using data of 377 schoolchildren age 10 to 17 years of both sexes. We studied metabolic variables associated with IR indicators, such as fasting insulin and blood glucose, to calculate the homeostatic model assessment (HOMA-IR), and we studied triglycerides (TG) to determine the TyG index. We obtained TyG cutoff values for IR using the receiver operation characteristic (ROC), with definitions of sensitivity (Sen), specificity (Spe), and area under the ROC curve (AUC), with the HOMA-IR as reference. Results: The cutoff points of the TyG index for IR in adolescents are 7.94 for both sexes, 7.91 for boys, and 7.94 for girls, indicating moderate discriminatory power. When we also considered anthropometric variables of excess weight [TyG-BMI (body mass index)] and visceral fat [TyG-WC (waist circumference)], these indexes reached AUC values higher than 0.72, enhancing their potential use for a good diagnosis. Conclusion: TyG has proven to be a useful instrument for identifying IR in adolescent health screening, with high discrimination capacity when added to anthropometric variables, making it a feasible and inexpensive option.

Micronuclei frequency and renal function markers in gym members: The moderating role of supplement intake.

This research investigates the moderating role of dietary supplement intake in the relationship between MNi frequency and renal markers in gym members. A cross-sectional study was carried out with gym members of all sexes, between 20 and 59 years of age, with data on supplement use obtained via questionnaire. Renal markers (urea and creatinine) were assessed by blood collection. Buccal mucosa cells were collected to assess MNi frequency by buccal micronucleus cytome assay. Moderation was tested using multiple linear regression models by PROCESS macro for SPSS. Results showed significant interactions for supplement use (p = 0.001) and supplement type, ergogenic (p = 0.003) and sports food (p = 0.003), with MNi for urea. For creatinine, only supplement use showed interaction with MNi frequency (p = 0.048). In conclusion, supplement intake is a moderator in the relationship between MNi frequency and renal function markers in gym members.

Caracterização genética, clínica e epidemiológica de pacientes com Covid-19 em uma região do Sul do Brasil / Genetic, clinical and epidemiological characterization of Covid-19 patients in South Brazil

Caracterizar o perfil epidemiológico, clínico e genético de pacientes com Covid-19. Realizou-se um estudo observacional e transversal com voluntários que tiveram diagnóstico de Covid-19 no período de abril de 2020 a maio de 2021 no município de Santa Cruz do Sul (RS, Brasil), no qual foram coletados dados clínicos e epidemiológicos, além de amostras de sangue para a identificação de polimorfismos no gene ACE2. Foram recrutados 87 indivíduos e destes, 16,7% necessitaram de internação hospitalar, sendo a maioria do sexo masculino. A obesidade foi a comorbidade mais frequente, no entanto, doenças cardiovasculares, hipertensão e diabetes apresentaram maior significância quando associadas às internações. Em relação à características genéticas, entre os voluntários não foram encontrados polimorfismos no gene ACE2. A pesquisa sugere que o sexo masculino e presença de comorbidades são importantes fatores de risco para a severidade da Covid-19.

Current paper characterizes the epidemiological, clinical and genetic profile of patients with Covid-19. An observational and cross-sectional study was carried out with volunteers diagnosed with Covid-19 between April 2021 and May 2021 in the municipality of Santa Cruz do Sul, Brazil; a blood sample also identified polymorphism in the ACE2 gene. 87 patients were recruited; 6.7% required hospitalization, the majority being male. Although obesity was a more frequent co-morbidity, cardiovascular diseases, hypertension and diabetes were more significant when associated with hospitalizations. In the case of genetic characteristics, polymorphisms were found in the ACE2 gene among volunteers. Important research suggests male gender and co-morbidities are risk factors for the severity of Covid-19.

Profile of tobacco growers with green tobacco sickness in Southern Brazil.

Introduction: Green tobacco sickness affects tobacco growers while handling tobacco leaves, regardless of the cultivation stage. Objectives: To characterize the sociodemographic and occupational profiles of tobacco growers with green tobacco sickness, as well as their health habits. Methods: This was a cross-sectional, descriptive study with information from a database obtained from a previous study conducted in a Southern Brazilian municipality. The data were analyzed using absolute and relative frequency. Results: We identified 8 cases of tobacco growers with green tobacco sickness, whose sociodemographic and occupational profiles and health habits were described. Conclusions: The data obtained in this study corroborate the existing literature on tobacco growers. The sociodemographic and occupational profiles and the health habits of our study participants have already been described in other studies, as well as of tobacco growers without green tobacco sickness.

From pregnancy to breastfeeding: adequate maternal body mass index is essential to prevent a high body mass index in your children.

OBJECTIVES: To verify the associations between prenatal and perinatal factors with offspring body mass index (BMI) and the moderator role of maternal BMI in this relationship. METHODS: Cross-sectional study developed with 1,562 children and adolescents aged between 6 and 17 years, as well as their mothers, from southern Brazil. The prenatal and perinatal factors, weight, and height for the calculation of maternal BMI were self-reported. For the calculation of BMI, weight and height of the child/adolescent were measured on an anthropometric scale with a coupled stadiometer. Linear regression models were used for the moderation analysis. All analyzes were adjusted for the mother's and child's age, sex, sexual maturation, skin color/race, and educational level. RESULTS: cesarean as type of delivery (ß=0.66; 95% CI=0.22 1.04; p=0.002) and pregnancy complications (ß=0.60; 95% CI=0.15 1.04; p=0.002) were positively associated with offspring BMI. Schoolchildren who were breastfed for 4-6 months showed -0.56 kg/m2 of BMI (95% CI=-1.06-0.06; p=0.02). Birth weight was also associated with BMI, with low weight being inversely (ß=-0.59; 95% CI=-1.03-0.15; p=0.008), while overweight was positively related (ß=0.84; 95% CI=0.08 1.60; p=0.02). The moderation analysis indicated a positive interaction between the mother's BMI and cesarean, pregnancy complications, and smoking with the offspring's BMI. On the other hand, there was an inverse association between breastfeeding from 7 to 12 months and the offspring BMI, only in mothers with high BMI. CONCLUSIONS: Adequate maternal BMI is essential to prevent a high BMI in their children, especially when considering the influence of prenatal and perinatal risk factors.

Metabolic risk is associated with sociodemographic characteristics in adolescents from both rural and urban regions from southern Brazil.

BACKGROUND: The prevalence of several cardiovascular metabolic disorders are increasingly cause for concern in adolescents worldwide. Given the complex interrelations between metabolic risk (MR) and sociodemographic variables, the present study aims to examine the association between the presence of MR with sociodemographic characteristics (sex, skin color, residential area, and parental socioeconomic status) in adolescents from Southern Brazil. METHODS: Cross-sectional study conducted with 1,152 adolescents (507 males) aged between 12 and 17 years. MR was assessed using a continuous score (cMetS; sum of Z-scores of the following variables: waist circumference, systolic blood pressure (SBP), glucose, high-density lipoprotein cholesterol [HDL-C, inverse], triglycerides [TG], and estimated cardiorespiratory fitness [CRF, inverse]). Poisson regression was used to examine associations between sociodemographic variables with the dichotomized cMetS and separate metabolic variables. The results were expressed with prevalence ratios (PR) and 95% confidence intervals (CI). RESULTS: The presence of MR (evaluated by the cMetS) was observed in 8.7% of adolescents. Higher MR was less prevalent among non-white adolescents (PR: 0.96; 95% CI: 0.93; 0.99). Adolescents living in rural areas had a lower prevalence of the following metabolic variables; low HDL-C (PR: 0.95; 95% CI: 0.94; 0.97), elevated TG (PR: 0.95; 95% CI: 0.92; 0.99), elevated glucose (PR: 0.96; 95% CI: 0.95; 0.98), and low CRF levels (PR: 0.88; 95% CI: 0.85; 0.92). Whereas, SBP was higher in those living in rural areas (PR: 1.11; 95% CI: 1.05; 1.17). In girls, there was a higher prevalence of raised TG (PR: 1.06; 95% CI: 1.02; 1.10) and lower levels of CRF (PR: 1.20; 95% CI: 1.16; 1.24), but a lower prevalence of elevated glucose (PR: 0.97; 95% CI: 0.97; 0.99). CONCLUSION: Higher MR prevalence was lower in those self-reporting non-white skin color and selected MR factors were less prevalent in those living in rural areas. The identification of groups at higher MR is important for early prevention and monitoring strategies for both Type 2 diabetes and later cardiovascular disease. Future studies should be conducted to assess the socio-cultural aspects of the relationships between MR and socio-cultural and lifestyle variables.

Body fat percentage, cardiorespiratory fitness and arterial blood pressure in children and adolescents: a longitudinal analysis.

BACKGROUND: A better understanding of how cardiorespiratory fitness (CRF) and adiposity interact to associate with arterial blood pressure over time remains inconclusive. Thus, the aim of the present study was to examine whether changes in CRF moderates the association between body fat percentage (BF%) and arterial blood pressure in children and adolescents. METHODS: This is an observational longitudinal study with 407 children and adolescents aged 8-17 years followed-up for three years from a city in Southern Brazil. Participants were evaluated in 2011 and 2014. CRF was measured by validated field-based tests following the Projeto Esporte Brazil protocols and peak oxygen uptake (VO2peak) was estimated. BF% was determined by the measures of tricipital and subscapular skinfolds using equations according to sex. Systolic and diastolic blood pressure (SBP, DBP) were measured with a sphygmomanometer according to standard procedures. Moderation analyses included multiple linear regression models adjusted for sex, age, pubertal status, height, socioeconomic level, skin color, and the arterial blood pressure variable itself at baseline. RESULTS: It was observed a significant inverse association between VO2peak at baseline with SBP (ß = - 0.646 CI95% = - 0.976 - 0.316) and DBP (ß = - 0.649 CI95% = - 0.923 - 0.375) at follow-up and a positive association between BF% at baseline with SBP (ß = 0.274; CI95% = 0.094 0.455) and DBP (ß = 0.301; CI95% = 0.150 0.453) at follow-up. In addition, results indicated a significant interaction term between changes in VO2peak and BF% at baseline with both SBP (p = 0.034) and DBP at follow-up (p = 0.011), indicating that an increase of at least 0.35 mL/kg/min and 1.78 mL/kg/min in VO2peak attenuated the positive relationship between BF% with SBP and DBP. CONCLUSION: CRF moderates the relationship between BF% and SBP and DBP in children and adolescents.

Integrated role of lifestyle habits in cardiometabolic risk factors according to sex in adolescents.

BACKGROUND: A healthy lifestyle should be adopted by young people to maintain cardiometabolic health. AIM: To verify the prevalence and the integrated role of lifestyle habits in cardiometabolic risk factors according to sex in adolescents. SUBJECTS AND METHODS: Cross-sectional study developed with 1502 adolescents, aged 10-17 years. Lifestyle habits included physical activity, screen time and sleep duration evaluated through a questionnaire. Cardiometabolic risk score (CMRS) was calculated by summing z-scores, divided by 6. For statistical analyses, multivariable binary and multinomial logistic regression models were used. RESULTS: 80.7% of the boys classified with adverse CMRS presented physical inactivity, compared to normal CMRS. In girls, 42.6% showed inadequate sleep compared to normal CMRS. Boys classified as inactive showed higher odds for obesity, as well as altered triglycerides (TGs), and systolic blood pressure, risk for cardiorespiratory fitness (CRF), high waist circumference, and CMRS, compared to the active. A prolonged screen time increased the odds for altered glucose and decreased the odds for altered TGs. In girls, inadequate sleep duration presented higher odds for overweight, obesity, risk for CRF, and high CMRS, compared to adequate sleep. CONCLUSION: Physical activity for boys and sleep duration for girls are important to maintain healthy metabolic health amongst youth.

Relationship between rs9939609 FTO polymorphism with waist circumference and body fat is moderated by ponderal index at birth in youth.

OBJECTIVE: The goal of this study was to analyze whether the relationship between the rs9939609 polymorphism of the fat mass and obesity-associated gene (FTO) with nutritional status is moderated by the ponderal index (PI) at birth in children and adolescents. METHODS: A cross-sectional study evaluated 382 schoolchildren aged 6-17 years. Anthropometric variables such as waist circumference (WC), body mass index (BMI) and body fat percentage (BF%) were used to assess nutritional status. Weight and height at birth were used for the PI calculation, which was divided into tertiles (lower, middle and upper). To compare the continuous variables between genotypes of the rs9939609 polymorphism, a recessive model (TT/AT vs. AA) and covariance analysis (ANCOVA) were used. RESULTS: The AA genotype of the rs9939609 polymorphism was associated with higher WC in schoolchildren born with lower PI (ß = 4.40; p = .048). However, for BF%, the genotype association was found in the upper PI tertile (ß = 7.35; p = .040). CONCLUSION: The relationship between WC and BF% with rs9939609 polymorphism (FTO) seems to be moderated by PI at birth. This is an important insight, since the data for intrauterine growth, genetic factors and the presence of obesity in children and adolescents are still contradictory.

Clustering of cardiometabolic risk factors and the continuous cardiometabolic risk score in children from Southern Brazil: a cross-sectional study.

PURPOSE: The present study aimed to verify the clustering of cardiometabolic risk factors for cardiovascular diseases (CVD) and its relationship with the continuous cardiometabolic risk score (cMetS). METHODS: Cross-sectional study with 631 children aged 6 to 9 years. Cardiorespiratory fitness, glucose, systolic blood pressure, total cholesterol/high-density lipoprotein cholesterol ratio, triglycerides, and waist circumference were assessed. The number of children in whom the risk factors were not independently distributed was analyzed. Z-scores were computed for each risk factor to calculate the cMetS. RESULTS: There was a high proportion of children with clustering of risk factors for CVD. The clustering of risk factors was apparent in 11.3% of the children for four or more risk factors, and 21.9% had three or more risk factors. The cMetS showed a linear relationship with the increase in the number of risk factors. A cMetS value higher than 0.91 indicated clustering of cardiometabolic risk factors amongst children. CONCLUSION: The use of clustering of cardiometabolic risk factors identified a high proportion of children with the presence of relevant cardiometabolic alterations. A cMetS value higher than 0.91 (relative to an international standard) indicated higher clustering of cardiometabolic risk factors amongst children.

Análise de componentes principais dos fatores de risco em adolescentes com excesso de peso antes e após um programa de intervenção / Analysis of principal components of risk factors in overweight adolescents before and after an intervention program

O objetivo do estudo é verificar o agrupamento dos fatores de risco cardiometabólicos e as possíveis mudanças deste, após um programa de intervenção interdisciplinar realizado com adolescentes com sobrepeso/obesidade. Os sujeitos foram alocados em dois grupos: grupo intervenção e grupo controle. O grupo intervenção participou de um programa com a duração de seis meses, com sessões três vezes por semana, que incluiu sessões com exercícios físicos, orientações nutricionais e psicológicas. Foram realizadas avaliações antropométricas, pressão arterial, aptidão cardiorrespiratória e coleta sanguínea para avaliação da glicose e perfil lipídico, antes e após o período de intervenção. Análise de componentes principais foi realizada para verificar o agrupamento dos fatores de risco nos períodos pré e pós-intervenção. A análise fatorial agrupou os componentes em três fatores no momento pré-intervenção, no grupo intervenção, que representou 83,88% da variância total do modelo. Já, no grupo controle, no período pré e pós-intervenção, e na avaliação pós-intervenção do grupo intervenção, os componentes foram agrupados em dois fatores centrais, que explicam, respectivamente, 68,38%, 71,23%, 75,19% da variância total do modelo. O grupo intervenção apresentou mudanças no agrupamento das variáveis nos resultados pós-intervenção, em comparação com o pré-teste. Nenhum componente central, que inter-relacionasse todos os demais fatores, nas quatro análises realizadas, foi encontrado. Entretanto, as variáveis antropométricas aparecem como os componentes de maior carga fatorial, agrupadas no fator 1, em todas as análises realizadas, fator que explica a maior variância total em torno das variáveis iniciais.

The objective of the study is to verify the grouping of cardiometabolic risk factors and their possible changes after an interdisciplinary intervention program performed with overweight/obese adolescents. The subjects were allocated in two groups: the intervention group and the control group. The intervention group participated in a program lasting six months, with sessions three times a week, which included sessions with physical exercises, nutritional and psychological orientations. Anthropometric evaluations, blood pressure, cardiorespiratory fitness, and blood collection were performed for evaluation of glucose and lipid profile before and after the intervention period. Main component analysis was performed to verify the grouping of risk factors in the pre-and post-intervention periods. The factorial analysis grouped the components into three factors at the pre-intervention time, in the intervention group, which represented 83.88% of the total variance of the model. In the control group, in the pre-and post-intervention period, and in the post-intervention evaluation of the intervention group, the components were grouped into two central factors, which explain, respectively, 68.38%, 71.23%, 75, 19% of the total variance of the model. The intervention group presented changes in the grouping of the variables in the post-intervention results, compared to the pre-test. No central component, which interrelated all the other factors, was found in the four analyzes. However, the anthropometric variables appear as the components of higher factor load, grouped in factor 1, in all the analyzes performed, a factor that explains the largest total variance around the initial variables.

Campos impregnados com iodo em cirurgia da coluna: impacto na infecção de sítio cirúrgico / Iodine-impregnated incision drapes in spine surgery: impact on surgical site infection / Paños quirúrgicos impregnados com yodo em cirugía de coluna: impacto en la infección del sitio quirúrgico

Objetivo: Avaliar o impacto de campos adesivos impregnados com iodo (CAII) na prevenção de infecção de sítio cirúrgico (ISC) de coluna vertebral. Método: Coorte retrospectiva que comparou desfecho de ISC em pacientes que utilizaram CAII com os que não usaram, de 2015 a 2019. Resultados: A frequência geral de ISC foi de 16,7%, com a taxa de ISC para os que utilizaram CAII de 40% e, entre os que não usaram, de 60%; p = 0,728; intervalo de confiança de 95% (IC95%) 0,19­3,11. A normotermia foi o único fator protetor independente para ISC (p = 0,043). O tratamento de complicações infecciosas acarretou o incremento de custo hospitalar de 83,6% a cada dia de atendimento. Os pacientes que utilizaram CAII tiveram 10 (± 4,9) dias a menos de permanência hospitalar. Conclusões: Os resultados sugerem que o uso de CAII não foi associado a menor risco de ISC. Esses dados podem ser úteis para o planejamento cirúrgico e a segurança do paciente.

Objective: To evaluate the impact of iodine-impregnated incision drapes (IIIDs) to prevent surgical site infection (SSI) in the spine. Method: Retrospective cohort study comparing SSI outcome in patients in which IIIDs were and were not used, from 2015 to 2019. Results: The overall frequency of SSI was 16.7%, with SSI rate among patients using and not using IIIDs of 40% and 60%, respectively; p = 0.728; 95% confidence interval (95%CI) 0.19­3.11. Normothermia was the only independent protective factor for SSI (p = 0.043). The treatment of infectious complications resulted in hospital costs increase of 83.6% each day of care. Patients who were treated with IIIDs stayed 10 days less (± 4.9) in hospital. Conclusions: The results suggest that the use of IIIDs was not associated with a lower risk of SSI. These data can be useful for surgical planning and patient safety.

Objetivo: Evaluar el impacto de las paños quirúrgicos adhesivos impregnados de yodo (IIIDS) en la prevención de la infección del sitio quirúrgico (ISQ) de la columna. Método: Cohorte retrospectiva que comparó el resultado de ISQ en pacientes que usaron IIIDS con los que no lo hicieron, de 2015 a 2019. Resultados: La frecuencia general de ISQ fue del 16.7%, con una tasa de ISQ para los que usaron IIIDS del 40% y, entre los que no lo usaron, 60%; p = 0,728; Intervalo de confianza del 95% (IC 95%) 0,19­3,11. La normotermia fue el único factor protector independiente para la ISQ (p = 0,043). El tratamiento de las complicaciones infecciosas supuso un aumento de los costes hospitalarios del 83,6% por día de atención. Los pacientes que utilizaron IIIDS tuvieron 10 (± 4,9) días menos de estancia hospitalaria. Conclusiones: Los resultados sugieren que el uso de IIIDS no se asoció con un menor riesgo de ISQ. Estos datos pueden ser útiles para la planificación quirúrgica y la seguridad del paciente.
