Perception of pregnant individuals, health providers and decision makers on interventions to cease substance consumption during pregnancy: a qualitative study.

BACKGROUND: Despite multiple recommendations and strategies implemented at a national and international level, cigarette smoking, alcohol consumption, and cannabis use during pregnancy remains high in most countries. The objective of this study was to examine key stakeholders' perception of the treatment interventions adopted in Spain, to identify political, organizational and personal factors associated with successful implementation, and to propose strategies for improvement. METHODS: A qualitative study with a phenomenological approach was conducted in 2022. The target groups were: (1) clinical decision makers in the field of addiction science, (2) health professionals who carry out treatment interventions, and (3) pregnant individuals who use tobacco, alcohol or cannabis. Two focus groups and eight in-depth interviews were conducted, recorded, and transcribed. Exploratory analysis and inductive open coding was performed, codes were merged into categories, and subcategories were identified. RESULTS: The analysis resulted in 10 subcategories which were further merged into three main categories: (1) Degree of adoption and utility of treatment interventions implemented; (2) Needs and demands with respect to the organization of treatment interventions; and, (3) Personal barriers to and facilitators for treatment. Respondents reported that despite multiple national and regional cessation initiatives, treatment interventions were rarely adopted in clinical practice. Health care administrators demanded reliable records to quantify substance use for better planning of activities. Health care professionals advocated for additional time and training and both echoed the importance of integrating cessation interventions into routine prenatal care and creating in-house specialized units. The difficulty in quitting, lack of awareness of risk for foetus and child and the controversial advice were identified as barriers by pregnant individuals. CONCLUSIONS: Consistent with previous work, this study found that cessation strategies implemented by the health authorities are not effective if they are not accompanied by organizational and behavioral changes. The current study identifies a set of factors that could be pivotal in ensuring the success of treatment interventions targeting tobacco, alcohol and cannabis use among pregnant individuals.

Population pharmacokinetics/pharmacodynamics of micafungin against Candida species in obese, critically ill, and morbidly obese critically ill patients.

BACKGROUND: Dosing in obese critically ill patients is challenging due to pathophysiological changes derived from obesity and/or critical illness, and it remains fully unexplored. This study estimated the micafungin probability of reaching adequate 24-h area under the curve (AUC0-24h)/minimum inhibitory concentration (MIC) values against Candida spp. for an obese/nonobese, critically ill/noncritically ill, large population. METHODS: Blood samples for pharmacokinetic analyses were collected from 10 critically ill nonobese patients, 10 noncritically ill obese patients, and 11 critically ill morbidly obese patients under empirical/directed micafungin treatment. Patients received once daily 100-150 mg micafungin at the discretion of the treating physician following the prescribing information and hospital guidelines. Total micafungin concentrations were determined by high-performance liquid chromatography (HPLC). Monte-Carlo simulations were performed and the probability of target attainment (PTA) was calculated using the AUC0-24/MIC cut-offs 285 (C. parapsilosis), 3000 (all Candida spp.), and 5000 (nonparapsilosis Candida spp.). Intravenous once-daily 100-mg, 150-mg, and 200-mg doses were simulated at different body weights (45, 80, 115, 150, and 185 kg) and age (30, 50, 70 and 90 years old). PTAs ≥ 90% were considered optimal. Fractional target attainment (FTA) was calculated using published MIC distributions. A dosing regimen was considered successful if the FTA was ≥ 90%. RESULTS: Overall, 100 mg of micafungin was once-daily administered for nonobese and obese patients with body mass index (BMI) ≤ 45 kg/m2 and 150 mg for morbidly obese patients with BMI > 45 kg/m2 (except two noncritically ill obese patients with BMI ~ 35 kg/m2 receiving 150 mg, and one critically ill patient with BMI > 45 kg/m2 receiving 100 mg). Micafungin concentrations in plasma were best described using a two-compartment model. Weight and age (but not severity score) were significant covariates and improved the model. FTAs > 90% were obtained against C. albicans with the 200 mg/24 h dose for all body weights (up to 185 kg), and with the 150 mg/24 h for body weights < 115 kg, and against C. glabrata with the 200 mg/24 h dose for body weights < 115 kg. CONCLUSION: The lack of adequacy for the 100 mg/24 h dose suggested the need to increase the dose to 150 mg/24 h for C. albicans infections. Further pharmacokinetic/pharmacodynamic studies should address optimization of micafungin dosing for nonalbicans Candida infections.

Risk factors for colonization by carbapenemase-producing enterobacteria at admission to a Surgical ICU: A retrospective study.

INTRODUCTION: In 2011, a hospital-wide outbreak of OXA-48 producing Klebsiella pneumoniae occurred in our hospital, an epidemiological setting of high ESBL-producing K. pneumoniae rates. This study identifies risk factors for colonization with carbapenemase-producing enterobacteria (CPE) at Surgical Intensive Care Unit (SICU) admission. METHODS: A 2-year retrospective study was performed in all patients admitted to the SICU that following routine had a rectal swab collected upon admission. RESULTS: Of 254 patients admitted, 41 (16.1%) harbored CPE (five showing two carbapenemase-producing isolates). Most frequent carbapenemase-producing isolates and carbapenemases were K. pneumoniae (39/46, 84.8%) and OXA-48 (31/46; 76.1%), respectively. Carriers significantly had higher rates of chronic renal disease, previous digestive/biliary endoscopy, hospitalization, ICU/SICU admission, intraabdominal surgery, and antibiotic intake, as well as higher median values of clinical scores (SOFA, SAPS II and APACHE II). In the multivariate analysis (R2=0.309, p<0.001), CPE carriage was associated with prior administration of 3rd-4th generation cephalosporins (OR=27.96, 95%CI=6.88, 113.58, p<0.001), ß-lactam/ß-lactamase inhibitor (OR=11.71, 95%CI=4.51, 30.43, p<0.001), abdominal surgery (OR=6.33, 95%CI=2.12, 18.89, p=0.001), and prior digestive/biliary endoscopy (OR=3.88, 95%CI=1.56, 9.67, p=0.004). CONCLUSIONS: A strong association between production of ESBLs and carriage of CPE (mainly OXA-48 producing K. pneumoniae) was found. According to the model, the co-selection of ß-lactamases by previous exposure to broad-spectrum cephalosporins and ß-lactam/ß-lactamase inhibitors (with lower relative risk), abdominal surgery and prior digestive/biliary endoscopy were factors associated with CPE carriage.

Incontinence-associated dermatitis: a cohort study in critically ill patients. / Dermatite associada à incontinência: estudo de coorte em pacientes críticos.

OBJECTIVES: Estimate incidence, determine risk factors and propose a prediction model for the development of incontinence- associated dermatitis critically ill adult patients. METHOD: Concurrent cohort study with 157 critically ill patients. Data collection was daily performed between February and July 2015, at a public teaching hospital of Belo Horizonte, Minas Gerais. Data was entered in a database and subjected to descriptive, survival and multivariate analysis. RESULTS: An overall incidence of 20.4% was obtained. Nineteen (19) risk factors significantly associated with the disorder were found. The variables identified in the risk prediction model were male, trauma, use of hypnotics/sedatives, lactulose, nutritional support, loose stools and complaints of burning. CONCLUSION: The results showed that dermatitis is a common clinical finding in critically ill adult patients and requires special attention from the nursing staff.

Influence of the CYP3A4/5 genetic score and ABCB1 polymorphisms on tacrolimus exposure and renal function in Brazilian kidney transplant patients.

BACKGROUND: Polymorphisms in genes encoding transport proteins and metabolizing enzymes involved in tacrolimus (TAC) disposition may be important sources of individual variability during treatment. OBJECTIVE: The aim of this study was to investigate the effect of combined CYP3A4 and CYP3A5 variants, using a CYP3A4/5 genetic score, and ABCB1 polymorphisms on therapeutic TAC monitoring and their relationship with clinical outcomes. MATERIAL AND METHODS: Brazilian kidney transplant recipients (n=151), who received TAC over 3 months after transplantation, were genotyped for CYP3A4 rs2242480 (g.20230G>A), CYP3A5 rs15524 (g.31611C>T) and rs776746 (g.6986A>G), ABCB1 rs1128503 (c.1236C>T), rs1045642 (c.3435C>T), and rs2032582 (c.2677G>T/A) polymorphisms. RESULTS: Frequencies of CYP3A4 g.20230A, CYP3A5 g.31611C, and g.6986A were 0.37, 0.26, and 0.28, respectively. These alleles were associated with TAC rapid metabolization and were used for CYP3A4/5 genetic score construction. A higher CYP3A4/5 genetic score was associated with higher TAC dose and lower concentrations for dose administered (Co/D, P<0.05). Ninety days after transplantation, the presence of two or more rapid metabolization alleles contributed toward 27.7% of Co/D variability and was associated with a lower estimated glomerular filtration rate values (P<0.05). For ABCB1, the frequencies of c.1236T, c.3435T, and c.2677T/A alleles were 0.42, 0.42, and 0.33/0.04. At 30 days after transplantation, patients carrying ABCB1 c.1236TT+c.3435TT+(c.2677TT+TA) genotypes had higher TAC Co/D than those with common or heterozygous genotypes (P<0.05). CONCLUSION: The results show the impact of the CYP3A4/5 genetic score on TAC exposure and renal function in Brazilian patients. Furthermore, ABCB1 polymorphisms, in a combined analysis, influenced TAC Co/D at 30 days after transplantation.

Physical methods for the treatment of fever in critically ill patients: a randomized controlled trial.

OBJECTIVE: To evaluate the effects of physical methods of reducing body temperature (ice pack and warm compression) in critically ill patients with fever. METHOD: A randomized clinical trial involving 102 adult patients with tympanic temperature ≥ 38.3°C of an infectious focus, and randomized into three groups: Intervention I - ice pack associated with antipyretic; Intervention II - warm compress associated with antipyretic; and Control - antipyretic. Tympanic temperature was measured at 15 minute intervals for 3 hours. The effect of the interventions was evaluated through the Mann-Whitney test and Survival Analysis. "Effect size" calculation was carried out. RESULTS: Patients in the intervention groups I and II presented greater reduction in body temperature. The group of patients receiving intervention I presented tympanic temperature below 38.3°C at 45 minutes of monitoring, while the value for control group was lower than 38.3°C starting at 60 minutes, and those who received intervention II had values lower than 38.3°C at 75 minutes of monitoring. CONCLUSION: No statistically significant difference was found between the interventions, but with the intervention group I patients showed greater reduction in tympanic temperature compared to the other groups. Brazilian Registry of Clinical Trials: RBR-2k3kbq. OBJETIVO: Avaliar o efeito de métodos físicos (bolsa de gelo e compressa morna) na redução da temperatura corporal de pacientes críticos com febre. MÉTODO: Ensaio clínico randomizado com 102 pacientes adultos e temperatura timpânica ≥ 38,3°C de foco infeccioso, aleatorizados em três grupos: Intervenção I ‒ bolsa de gelo associada a antitérmico; Intervenção II ‒ compressa morna associada a antitérmico; e Controle ‒ antitérmico. A temperatura timpânica foi mensurada em intervalos de 15 minutos durante 3 horas. O efeito das intervenções foi avaliado pelo teste Mann-Whitney e Análise de Sobrevivência. Cálculo do "Effect size" foi procedido. RESULTADOS: Os pacientes dos grupos Intervenção I e II apresentaram maior redução na temperatura corporal. A partir de 45 minutos de acompanhamento o grupo de pacientes que recebeu a Intervenção I apresentou valor da temperatura timpânica inferior a 38,3°C, os do grupo controle valor menor que 38,3°C a partir de 60 minutos e os que receberam a Intervenção II, valor menor que 38,3°C com 75 minutos de acompanhamento. CONCLUSÃO: Não foi encontrada diferença estatística significativa entre as intervenções, porém os pacientes do grupo Intervenção I apresentaram maior redução da temperatura timpânica em relação aos demais grupos.

PIUS-a: Problematic Internet Use Scale in adolescents. Development and psychometric validation.

Adolescents' use of the Internet is becoming a matter of great concern for different sectors of society. The psychological and behavioural consequences of problematic Internet use in young people demands quick and effective answers. One of the major challenges in this context is the development of empirically validated tools, which would facilitate early detection and screening for potential risk cases. This is precisely the aim of this paper. Based on a sample of 1,709 secondary-school students from Galicia (a region in northern Spain) aged 11 to 17 (M = 13.74, SD = 1.43), the analysis carried out permitted us to present a brief and simple tool (with just 11 items). It has substantial theoretical support, since both the existing background information and the views of experts from the academic and professional spheres were taken into account in the course of its development. The scale is adapted to the Spanish cultural context and to the language of young people. It has satisfactory psychometric properties in terms of reliability of the scores (α = .82), evidence of its internal structure (tested via a Confirmatory Factorial Analysis), sensitivity (81%), and specificity (82.6%). Moreover, its use enables the gradation of adolescents on a risk or problematic Internet use continuum. In our view, all of this lends it enormous applied potential in both the educational and clinical contexts.

Problematization methodology's impact on nursing and medical students' knowledge about hypodermoclysis: quasi-experimental study.

OBJECTIVE: to analyze the problematization methodology impact on the knowledge of nursing and medical students about hypodermoclysis. METHOD: quasi-experimental study conducted with 22 undergraduate nursing and medical students from a public Brazilian higher education institution. The students participated in the educational intervention using the problematization methodology based on the Arch of Maguerez. A previously validated questionnaire was used to determin' the students' knowledge level about hypodermoclysis. This instrument was applied before and after the educational intervention. The results were compared by McNemar's test and Student's t test for paired samples. RESULTS: when comparing the correct answers before and after the intervention, there was a significant increase in 75% of the questions (p<0.05), including theoretical and practical aspects of hypodermoclysis. The mean score on students' self-assessment of the ability to explain (0.9 versus 5.9 points) and perform hypodermoclysis (1.9 versus 5.0) was significantly higher after applying the problematization methodology (p<0.001). CONCLUSION: the problematization methodology had a positive impact on the students' knowledge about hypodermoclysis. The number of correct answers after the educational intervention was higher than the initial assessment. The problematization methodology can be incorporated into the teaching-learning process of nursing and medical students for teaching procedures such as hypodermoclysis. BACKGROUND: (1) The problematization methodology had a positive impact on students' knowledge. BACKGROUND: (2) The number of correct answers after the educational intervention increased. BACKGROUND: (3) Problematization can be incorporated into the teaching of nursing and medicine. BACKGROUND: (4) The teaching-learning process through active methodologies should be encouraged. BACKGROUND: (5) Problematization has the potential to develop cognitive and attitudinal skills.

HTLV-1 uveitis in Colombia, an underrecognized complication of a hitherto neglected condition: a case series.

Three Colombian patients with chronic HTLV-1 infection and severe intermediate and/or posterior uveitis are described. In one case, retinal ablation was necessary due to extensive peripheral degeneration, while the other two were successfully managed with local anti-inflammatory therapy. Gradual resolution of ocular findings was observed in all three patients on follow-up. Uveitis is a rarely recognized late complication of this infection, which represents a diagnostic and therapeutic challenge for clinicians in endemic countries. The real extension of HTLV-1 prevalence in Colombia and the frequency of its ophthalmologic complications remain to be determined.

[Nursing diagnoses identified in inpatients of an adult intensive care unit]. / Diagnósticos de enfermagem identificados em pacientes internados em Unidade de Terapia Intensiva Adulto.

This descriptive study was performed to identify the nursing diagnoses in the records of the inpatients of an adult intensive care unit, and map the most frequent diagnosis according to the Fundamental Human Needs. The sample consisted of 44 patient records. A total of 1,087 nursing diagnoses were identified. After excluding the repetitions, 28 different diagnoses were identified. Twenty-five diagnoses were related to psychobiological needs, and three to psychosocial needs. Further studies should identify, among the formulated nursing diagnoses and the affected human needs, which problems were solved and for what needs the care is predominantly developed. The present study results are important for the organization of teaching content for students and nurses, preparing them to consider human beings as a whole when providing care, considering their biological, emotional, and spiritual aspects.

Factors associated with the incidence of pressure wounds in critical patients: a cohort study.

OBJECTIVES: to identify the incidence of pressure wound in critical patients and its associated factors. METHODS: retrospective cohort study, based on the analysis of 369 critical patients' records. Descriptive and inferential statistics were used, as well as logistic regression. RESULTS: the incidence of pressure wounds was 11.4%. Patients who had been hospitalized for four days or more (OR 2.99; CI95% 1.15-7.78), used nasoenteric tubes (OR: 3.81; CI95%: 1.4010.38), vesical drainage catheters (OR: 4.78; CI95%: 1.31-17.38) and tracheostomy (OR: 3.64; CI95%: 1.48-8.97) had a higher chance of developing pressure wounds. The mean score of the Braden scale among participants who developed (14.2 points) pressure wounds was statistically different (p<0.001) than that of those who did not (12.3 points). CONCLUSIONS: the incidence of pressure wounds was associated with a higher time in the unit, the use of nasoenteric tubes, vesical drainage catheters, and tracheostomies were associated with a higher time of hospitalization in the unit.

[SBIRT model as a prevention strategy against addiction with and without substance in teenagers.] / El modelo SBIRT como estrategia de prevención de las adicciones con y sin sustancia en adolescentes.

A high prevalence of adolescent substance use, risky consumption patterns and the decrease in the age of initiation, together with the growth of non-substance addictions, represent a huge challenge for Public Health. This suggests the need for a change of focus in the work of the primary care settings, which must be more proactive in the early detection and intervention. Although there are some previous experiences in Spain, we do not have a duly standardised system, based on clinical practice and validated in consulting rooms, which could be used in a general, simple, and guaranteed manner. The SBIRT (Screening, Brief Intervention and Referral to Treatment) model, developed in the United States and conceived from a Public Health perspective, might represent such a paradigm shift. The aim of this paper was to provide researchers and professionals with a review of the available evidence in different countries, with a view to implementing it in Spain, where SBIRT remains a challenge. In addition, theoretical and technical foundations, and potential of the SBIRT are described. Not only its possible benefits and opportunities are put on the table, but also the shortcomings, limitations and needs that must be overcome for SBIRT implementation to be possible.

La alta prevalencia del consumo de sustancias entre los adolescentes, los preocupantes patrones de consumo y el descenso de las edades de inicio, junto al crecimiento de las adicciones sin sustancia, suponen uno de los grandes desafíos actuales en materia de Salud Pública. Ello sugiere la necesidad de un cambio de enfoque en la labor de los dispositivos de Atención Primaria (AP), que han de ser más proactivos en la detección e intervención precoz. Aunque en España existen algunas experiencias previas, no disponemos de una sistemática debidamente protocolizada, fundamentada clínicamente y validada en las consultas, que pueda ser utilizada de forma generalizada, sencilla y con garantías por los profesionales. El modelo SBIRT (Screening, Brief Intervention and Referral to Treatment), desarrollado en Estados Unidos y concebido desde un enfoque de Salud Púbica, representa ese cambio de paradigma. El objetivo de este trabajo, además de dar a conocer los fundamentos teóricos, técnicos y potencialidades del SBIRT, fue poner a disposición de investigadores y profesionales una revisión de la evidencia disponible en diferentes países, de cara a su posible implantación en España, donde a pesar de la existencia de experiencias precedentes puntuales, constituye todavía una cuenta pendiente. Se ponen sobre la mesa no sólo los posibles beneficios y oportunidades, sino también las carencias, limitaciones y necesidades que han de superarse para que la implementación del SBIRT sea posible.

Incidence and Prediction of Unstable Blood Glucose Level among Critically Ill Patients: A Cohort Study.

PURPOSE: To evaluate the incidence and the prediction of unstable blood glucose level among critically ill patients hospitalized in an intensive care unit. METHODS: A cohort study was conducted with 62 adult patients hospitalized at an intensive care unit of a hospital located in Minas Gerais, Brazil, between March and July of 2017. Patient's demographic information, along with scores for Simplified Acute Physiology Score III, primary medical diagnosis, discharge status, diagnosis of diabetes and/or sepsis, length of stay, glycemic variability, type of nutrition, types of medications and treatments, and oxygen therapy were collected daily. A daily venous blood sample was collected to measure blood glucose levels during the patient's hospitalization period. Bivariate analysis was used to explore the association among the potential diagnostic indicators and the outcome of unstable blood glucose levels. Multivariate Cox regression was used to identify the potential predictors for the outcome. FINDINGS: Of the total of 62 participants, 45.1% (n=28) had unstable blood glucose level. Among the 28 patients with unstable blood glucose levels, half of them (n=14, 50%) had hypoglycemia and the other half had hyperglycemia (n=14, 50%). Decreased number of days hospitalized and the use of intensive glucose control with regular insulin were associated with decreased odds of developing hyperglycemia. The presence of mechanical ventilation was associated with a higher risk for the development of hypoglycemia. CONCLUSIONS: This study provides knowledge and evidence of diagnostic indicators for unstable blood glucose levels that are not currently included in the NANDA-International terminology for the nursing diagnosis Risk for unstable blood glucose level (00179). IMPLICATIONS FOR NURSING PRACTICE: This study identified important diagnostic indicators that nurses can observe during the assessment to identify patients that are at risk for developing unstable blood glucose level and provide the appropriate care.

OBJETIVO: Avaliar a incidência e predição de glicemia instável em pacientes adultos internados em uma Unidade de Terapia Intensiva. MÉTODO: Estudo de coorte concorrente, realizada entre março e julho de 2017, com amostra de 62 pacientes. As variáveis independentes coletadas da admissão do paciente a unidade foram sexo, raça, idade, Simplified Acute Physiology Score III, diagnóstico de internação, tipo de saída, diabetes, sepse, tempo de permanência, variabilidade glicêmica, tipo de nutrição, medicamentos e terapêutica, e oxigenoterapia (cateter nasal e ventilação mecânica). Os dados foram analisados por estatística descritiva e análise de sobrevida com teste de Log-rank e regressão multivariada de Cox. RESULTADOS: Dos 62 pacientes, 45,1% (n=28) desenvolveram a glicemia instável. Dos 28 pacientes com glicemia instável, metade (n=14, 50%) apresentou hipoglicemia, e a outra metade apresentou hiperglicemia (n=14, 50%). Menor tempo de permanência e controle estrito da glicemia foram fatores de proteção para desenvolvimento de hiperglicemia. Ventilação mecânica foi associada ao desenvolvimento de hipoglicemia. CONCLUSÃO: Este estudo fornece conhecimento e evidência sobre indicadores diagnósticos para o desenvolvimento de glicemia instável, que atualmente não estão incluídos na terminologia da NANDA-Internacional para o diagnóstico de enfermagem Risco de glicemia instável. IMPLICAÇÕES PARA ENFERMAGEM: Este trabalho contribui para o aperfeiçoamento da Taxonomia da NANDA-Internacional e, por conseguinte, da linguagem padronizada de enfermagem.

Changes in body temperature of critically ill patients submitted to bed bathing: a crossover clinical trial.

OBJECTIVES: to compare tympanic and axillary body temperature values of critical patients before and after the traditional and dry bed bath. METHODS: this is a randomized, open crossover clinical trial conducted with 50 adult critical patients. All patients received both types of bed bathing. The tympanic and axillary temperature values were measured at the beginning and end of the baths. The Wilcoxon test or paired Student's t test was used. RESULTS: elderly and male patients predominated. There was no significant difference between tympanic temperature medians measured during the traditional bed bath (p=0.707) and dry bath (p=0.101). Axillary temperature means reduced at the end of the baths (p=0.001), being 36.12ºC in the traditional bath and 35.92ºC in dry bath. CONCLUSIONS: bed bath, regardless of the method used, caused a reduction in critical patients' axillary temperature.

Risk factors for early onset of diabetic nephropathy in pediatric type 1 diabetes.

AIM: Diabetic nephropathy (DN) is a frequent complication in patients with long-standing type 1 diabetes mellitus (DM1). The objective of this study was to assess the prevalence of DN in DM1 patients diagnosed during childhood and its association with clinical and metabolic variables, such as age at diagnosis of DM1, glucose control, dyslipidemia, hypertension and the occurrence of diabetic retinopathy (DR). METHODS: The medical records of 205 patients admitted to the Pediatric Endocrinology Division at the Hospital das Clinicas da Universidade Federal de Minas Gerais, in Belo Horizonte, Brazil, were analyzed. For the analysis of survival and prognostic factors, the Kaplan-Meyer method and the COX regression model were used. RESULTS: The mean disease duration was 11.32 +/- 4.02 years and the mean age at diagnosis was 6.10 +/- 3.54 years. Microalbuminuria was present in 11.2% of them, proteinuria in 6.8% and end-stage renal disease (ESRD) in 2.9%. There was a significant association between the occurrence of microalbuminuria or proteinuria and poor glucose control (p=0.025 and p=0.005, respectively), higher LDL cholesterol levels (p=0.006 and p=0.004, respectively) and age greater than 6 years at diagnosis (p=0.049 and p=0.05, respectively). Proteinuria was also associated to the occurrence of DR (p=0.016). CONCLUSION: Our data showed that the prevalence of DN was higher than expected in this young population studied, especially considering the most severe forms. Clinical and laboratory factors associated to ND were: poor long-term glucose control, higher levels of LDL-C, higher age at diagnosis and the occurrence of DR.

Effects of dry and traditional bed bathing on respiratory parameters: a randomized pilot study.

OBJECTIVE: to compare the time for performance of dry and traditional bed bathing and its effects on transcutaneous arterial oxygen saturation and respiratory rates in critical adult patients. METHOD: pilot study of a randomized, open, crossover clinical trial, performed with 15 adult critically ill patients. Each patient received a dry and a traditional bed bath. Analysis of variance with repeated measures was used, adopting p-value ≤ 0.05. RESULTS: most patients were male (73.3%), white (66.7%), with a mean age of 69.7 years. The dry bath was faster (20.0 minutes) than the traditional bath (30.0 minutes) (p<0.001). There was no significant difference between the patients' saturation means between baths (p=0.381), with 94.7% for the dry bath and 95.2% for the traditional bath. During the traditional bath, the patients' respiratory rate mean was higher (24.2 incursions per minute) and statistically different (p<0.001) from the value obtained for the dry bath (20.5 incursions per minute). CONCLUSION: the dry bath had a shorter duration than did the traditional bath, resulting in less patient exposure. The traditional bed bath had a negative effect on patients' respiratory rate, increasing it. Brazilian Registry of Clinical Trials (ReBEC): RBR-5qwkqd.

Differential expression of genes related to calcineurin and mTOR signaling and regulatory miRNAs in peripheral blood from kidney recipients under tacrolimus-based therapy.

BACKGROUND: Genetic and epigenetics factors have been implicated in drug response, graft function and rejection in solid organ transplantation. Differential expression of genes involved in calcineurin and mTOR signaling pathway and regulatory miRNAs was analyzed in the peripheral blood of kidney recipient cohort (n=36) under tacrolimus-based therapy. METHODS: PPP3CA, PPP3CB, MTOR, FKBP1A, FKBP1B and FKBP5 mRNA expression and polymorphisms in PPP3CA and MTOR were analyzed by qPCR. Expression of miRNAs targeting PPP3CA (miR-30a, miR-145), PPP3CB (miR-10b), MTOR (miR-99a, miR-100), and FKBP1A (miR-103a) was measured by qPCR array. RESULTS: PPP3CA and MTOR mRNA levels were reduced in the first three months of treatment compared to pre-transplant (P<0.05). PPP3CB, FKBP1A, FKBP1B, and FKBP5 expression was not changed. In the 3rd month of treatment, the expression of miR-99a, which targets MTOR, increased compared to pre-transplant (P<0.05). PPP3CA c.249G>A (GG genotype) and MTOR c.2997C>T (TT genotype) were associated with reduced expression of PPP3CA mRNA and MTOR, respectively. FKBP1B mRNA levels were higher in patients with acute rejection (P=0.026). CONCLUSIONS: The expression of PPP3CA, MTOR and miR-99a in the peripheral blood of renal recipients is influenced by tacrolimus-based therapy and by PPP3CA and MTOR variants. These molecules can be potential biomarkers for pharmacotherapy monitoring.

Evaluating the "satisfaction" and "self-confidence" in nursing students in undergoing simulated clinical experiences.

OBJECTIVE: To evaluate the "satisfaction" and "self-confidence" constructs in nursing students who underwent simulated clinical experiences in semiology and semiotechnique disciplines. METHOD: A descriptive study developed with Nursing students from a federal public university in the interior of Minas Gerais through weekly simulated workshops. The "satisfaction" and "self-confidence" constructs were evaluated by the "Student Satisfaction and Self-Confidence with Learning Scale" and "Simulated Clinical Experiences Satisfaction Scale". RESULTS: The final sample was 45 students. Most were more satisfied (overall average = 4.18) than self-confident (overall average = 4.12). The Spearman correlation test identified a significant and positive association between the "satisfaction" and "self-confidence" constructs. CONCLUSION: Students feel self-confident and satisfied with the use of simulation as an active teaching-learning methodology, highlighting that the higher the satisfaction level, the greater the student's self-confidence.

Adaptation of software with the nursing process for innovation units.

OBJECTIVE: To adapt data collection of the Information System software with the nursing process in Intensive Therapy for use in medical and surgical clinic units. METHODS: A descriptive study developed in three stages. The first consisted of team training; in the second, the software was applied in clinical practice with 100 patients; and in the third, we analyzed the modifications to be done. RESULTS: There was inter-observer agreement of 91%, followed by application of the software in 100 patients. In the "patient registration" module, it was suggested the exclusion of one item, inclusion of six and modification of four of them. In the anamnesis screens, no items were flagged to be deleted; 26 inclusions and 7 changes were proposed. In the physical examination screens, it was suggested the exclusion of 31 items, inclusion of 26 and modification of 27. CONCLUSION: Modifying information systems and going through stages methodologically constructed and implemented was important.

Problematization methodology's impact on nursing and medical students' knowledge about hypodermoclysis: quasi-experimental study / Impacto de la metodología de problematización en el conocimiento de estudiantes de enfermería y medicina sobre hipodermoclisis: estudio cuasiexperimental / Impacto da metodologia de problematização no conhecimento de estudantes de enfermagem e medicina sobre hipodermóclise: estudo quase experimental

Objective: to analyze the problematization methodology impact on the knowledge of nursing and medical students about hypodermoclysis. Method: quasi-experimental study conducted with 22 undergraduate nursing and medical students from a public Brazilian higher education institution. The students participated in the educational intervention using the problematization methodology based on the Arch of Maguerez. A previously validated questionnaire was used to determin' the students' knowledge level about hypodermoclysis. This instrument was applied before and after the educational intervention. The results were compared by McNemar's test and Student's t test for paired samples. Results: when comparing the correct answers before and after the intervention, there was a significant increase in 75% of the questions (p<0.05), including theoretical and practical aspects of hypodermoclysis. The mean score on students' self-assessment of the ability to explain (0.9 versus 5.9 points) and perform hypodermoclysis (1.9 versus 5.0) was significantly higher after applying the problematization methodology (p<0.001). Conclusion: the problematization methodology had a positive impact on the students' knowledge about hypodermoclysis. The number of correct answers after the educational intervention was higher than the initial assessment. The problematization methodology can be incorporated into the teaching-learning process of nursing and medical students for teaching procedures such as hypodermoclysis.

Objetivo: analizar el impacto de la metodología de problematización en el conocimiento de estudiantes de enfermería y medicina sobre hipodermoclisis. Método: estudio cuasiexperimental realizado con 22 estudiantes de enfermería y medicina de una institución pública de educación superior brasileña. Los estudiantes participaron de la intervención educativa utilizando la metodología de problematización basada en el Arco de Maguerez. Se utilizó un cuestionario previamente validado para determinar el nivel de conocimiento de los estudiantes sobre la hipodermoclisis. Este instrumento se aplicó antes y después de la intervención educativa. Los resultados se compararon mediante la prueba de McNemar y la prueba t de Student para muestras pareadas. Resultados: al comparar las respuestas correctas antes y después de la intervención, se observó un aumento significativo en el 75% de las preguntas (p<0,05), que incluye aspectos teóricos y prácticos de la hipodermoclisis. El puntaje promedio en la autoevaluación de los estudiantes con respecto a su capacidad para explicar (0,9 versus 5,9 puntos) y realizar hipodermoclisis (1,9 versus 5,0) fue significativamente mayor después de aplicar la metodología de problematización (p<0,001). Conclusión: la metodología de problematización tuvo impacto positivo en el conocimiento de los estudiantes sobre la hipodermoclisis. El número de respuestas correctas luego de la intervención educativa fue mayor que en la evaluación inicial. La metodología de problematización puede incorporarse al proceso de enseñanza-aprendizaje de estudiantes de enfermería y medicina para enseñar procedimientos como la hipodermoclisis.

Objetivo: analisar o impacto da metodologia de problematização no conhecimento de estudantes de enfermagem e medicina sobre hipodermóclise. Método: estudo quase-experimental realizado com 22 estudantes de graduação em enfermagem e medicina de uma instituição pública de ensino superior brasileira. Os alunos participaram da intervenção educacional usando a metodologia de problematização baseada no Arco de Maguerez. Um questionário previamente validado foi usado para determinar o nível de conhecimento dos alunos sobre hipodermóclise. Esse instrumento foi aplicado antes e depois da intervenção educacional. Os resultados foram comparados pelo teste de McNemar e pelo teste t de Student para amostras pareadas. Resultados: ao comparar as respostas corretas antes e depois da intervenção, houve um aumento significativo em 75% das questões (p<0,05), incluindo aspectos teóricos e práticos da hipodermóclise. A pontuação média na autoavaliação dos alunos quanto à capacidade de explicar (0,9 versus 5,9 pontos) e realizar a hipodermóclise (1,9 versus 5,0) foi significativamente maior após a aplicação da metodologia de problematização (p<0,001). Conclusão: a metodologia de problematização teve um impacto positivo no conhecimento dos alunos sobre hipodermóclise. O número de respostas corretas após a intervenção educacional foi maior do que na avaliação inicial. A metodologia de problematização pode ser incorporada ao processo de ensino-aprendizagem de estudantes de enfermagem e medicina para o ensino de procedimentos como a hipodermóclise.
