RESUMO

BACKGROUND: Placing central venous lines under ultrasonographic guidance reduces the complications of the procedure. AIM: To compare prevalences of complications of central venous line placements with or without ultrasonographic guidance. MATERIAL AND METHODS: Descriptive study that contemplated the comparison of two groups of patients subjected to a central venous line placement at a nephrology service for renal replacement therapy. In one group of 100 patients, the line was placed without ultrasonographic guidance between 2008 and 2012. Between 2015 and 2017 the line was placed in 138 patients using ultrasonographic guidance. The prevalences of complications with both types of procedures were recorded. RESULTS: The frequency of complications of procedures with and without ultrasonographic guidance was 0.7 and 18% respectively (prevalence ratio 0.04, 95% confidence interval 0-0.3). Ninety five percent of recorded complications were arterial puncture, followed by hematomas in 10% and pneumothorax in 5%. The higher prevalence of complications was observed in emergency line placement without ultrasonographic guidance. There was a direct association between the number of line placement attempts in a single procedure and the prevalence of complications. CONCLUSIONS: Ultrasonographic guidance is associated with a reduction in the prevalence of central venous line complications.

RESUMO

Resumen El propósito de este trabajo fue estudiar la efectividad de intervenciones basadas en Mindfulness sobre el nivel de hemoglobina glicada —HbA1c— en pacientes con diabetes mellitus tipo 2 —DM2—. Se realizó una revisión sistemática e integración metanalítica preliminar. La búsqueda de los estudios se realizó en las siguientes bases: PubMed, Bireme, Web of Science, SciELO, Embase, EBSCOhost, SCOPUS, Psychology Database. Se identificaron 10 artículos: cuatro fueron llevados a cabo en Estados Unidos, dos en Irán, uno en Alemania, uno en Australia, uno en Tailandia y uno en Inglaterra. Se observó una reducción en los niveles de la HbA1c utilizando Mindfulness en comparación a los grupos controles (p < 0,02). Además, se observó un efecto diferenciado al analizar según número de participantes, sexo y tiempo de seguimiento. Se concluyó que el uso de intervenciones basadas en Mindfulness tendría un efecto indirecto sobre la reducción de la hemoglobina glicada.


Abstract The purpose of this paper was to study the effectiveness of Mindfulness-based interventions on the level of glycated hemoglobin —HbA1c— in patients with type 2 diabetes mellitus —DM2—. A systematic review and preliminary meta-analytic integration was performed. The search of the studies was carried out in the following bases: PubMed, Bireme, Web of Science, SciELO, Embase, EBSCOhost, SCOPUS, Psychology Database. Ten articles were identified: four were published in the United States, two in Iran, one in Germany, one in Australia, one in Thailand and one in England. A reduction in HbA1c levels was observed using Mindfulness compared to control groups (p <0,02). In addition, according to the number of participants, sex and time of follow-up a differentiated effect was found. It was concluded that the use of interventions based on Mindfulness would have an indirect effect on the reduction of glycated hemoglobin (HbA1c).

RESUMO

Background Affordable interventions to improve metabolic control of Type 2-Diabetes Mellitus are increasingly necessary. Aim To review systematically the existing literature on the effects of psychological interventions on Type-2 Diabetes Mellitus compensation. Material and Methods We performed a systematic literature review and meta-analysis on the effectiveness of psychological interventions implemented for Type-2 Diabetes Mellitus patients. Research included the following electronic databases: PubMed, Bireme, Web of Science, SciELO, Embase, EBSCOhost, SCOPUS, Psychology Database. Results Most studies showed a decrease in the level of glycated hemoglobin after interventions, which applied different initiatives complementary to standard medical treatment. Mainly, these interventions encompassed training for self-monitoring and control of diabetes based on cognitive behavioral psychology, counseling, self-assessment and physical-spiritual work based on transpersonal psychology. Conclusions Psychological tools could be an adjunct to the standard medical treatment for patients with Type-2 Diabetes Mellitus, reducing glycated hemoglobin levels and improving self-regulation, disease awareness and adherence from the self-efficacy perception perspective.

RESUMO

Chronic kidney disease is associated with an increase in cardiovascular risk and mortality, and a decrease in the health-related quality of life. It is known that the physical capacity of patients with chronic kidney disease is lower than their healthy counterparts. It also decreases progressively after the start of hemodialysis, even leading to the loss of functional independence. There is a positive association between exercise and improvement of many targets in chronic kidney disease, especially in dialysis patients, such as cellular apoptosis, immune improvement and inflammation. In addition, several clinical studies and systematic reviews show an improvement in different clinical and laboratory variables and suggest a lower mortality, proving a reduction of health care economic costs. Exercise intervention in dialysis is safe. Although different guidelines promote exercise, it is necessary to work on its implementation on a large scale.

RESUMO

Background Losartan is widely used in many clinicals settings. Its dosage is related to the genetic characteristics of CYP2C9 enzymatic activity, which metabolizes losartan to its active form E-3174, responsible for the antihypertensive effect. Aims To identify the frequency of allelic variants CYP2C9*2 and CYP2C9*3 in hypertensive patients and to compare genotypes with a healthy Chilean population. To relate polymorphisms with the losartan dosing to obtain an optimal blood pressure. Material and Methods We studied 30 patients with controlled essential hypertension using losartan with normal liver function, and 202 healthy people. Peripheral blood DNA genotyping was performed by polymerase chain reaction to identify the polymorphisms. Allelic and genotypic frequencies were compared. Results In hypertensive patients, allelic frequencies were 0.85 (CYP2C9*1), 0.05 (CYP2C9*2) and 0.1 (CYP2C9*3). Genotypic frequencies were 73.3% (CYP2C9*1/*1), 6.7% (CYP2C9*1/*2), 16.7% (CYP2C9*1/*3) and 3.3% (CYP2C9*2/3); observing a significantly higher frequency of the allele CYP2C9*3 (p=0.041) and CYP2C9*1/*3 genotype (p=0.04). A non-significant tendency to need a larger dose of losartan was observed with the CYP2C9 * 3 allele, with an odds ratio (OR) of 1.46 (95% confidence intervals (CI) 0.01-18.64). The same tendency was observed with the need to use losartan twice a day, obtaining an OR of 5.88 (CI 0.54 -62.14). Conclusions There could be a relationship between the presence of CYP2C9 polymorphisms and the pathogenesis of hypertension. The presence of CYP2C9*3 is associated with the need for higher doses of losartan, possibly due to a decrease in the conversion of losartan to E-3174.
