RESUMO

In COVID-19 patients, procalcitonin (PCT) and C-reactive protein (CRP) performance in identifying bacterial infections remains unclear. Our study aimed to evaluate the association of PCT and CRP with secondary infections acquired during ICU stay in critically ill COVID-19 patients. This observational study included adult patients admitted to three COVID-19 intensive care units (ICUs) from February 2020 to May 2022 with respiratory failure caused by SARS-CoV-2 infection and ICU stay ≥ 11 days. The values of PCT and CRP collected on the day of infection diagnosis were compared to those collected on day 11 after ICU admission, the median time for infection occurrence, in patients without secondary infection. The receiver operating characteristic curve (ROC) and multivariate logistic model were used to assess PCT and CRP association with secondary infections. Two hundred and seventy-nine patients were included, of whom 169 (60.6%) developed secondary infection after ICU admission. The PCT and CRP values observed on the day of the infection diagnosis were larger (p < 0.001) than those observed on day 11 after ICU admission in patients without secondary infections. The ROC analysis calculated an AUC of 0.744 (95%CI 0.685-0.803) and 0.754 (95%CI 0.695-0.812) for PCT and CRP, respectively. Multivariate logistic models showed that PCT ≥ 0.16 ng/mL and CRP ≥ 1.35 mg/dL were associated (p < 0.001) with infections acquired during ICU stay. Our results indicated that in COVID-19 patients, PCT and CRP values were associated with infections acquired during the ICU stay and can be used to support, together with clinical signs, rather than predict or rule out, the diagnosis of these infections.

RESUMO

OBJETIVO: Determinar os fatores preditores de abandono do tratamento da tuberculose pulmonar, preconizado pelo Ministério da Saúde do Brasil, em pacientes bacilíferos virgens de tratamento atendidos na cidade de Porto Alegre (RS). MÉTODOS: Estudo de caso-controle envolvendo seis unidades básicas de saúde de referência para o tratamento da tuberculose em Porto Alegre, com a revisão dos prontuários de todos os casos de abandono do tratamento por parte de pacientes com tuberculose pulmonar bacilíferos e virgens de tratamento entre 2004 e 2006. Os pacientes incluídos no estudo foram pareados com pacientes com características semelhantes e cujo desfecho foi de cura. Foram realizadas análises univariada e multivariada. RESULTADOS: Dos 2.098 pacientes incluídos no estudo, 218 (10,4 por cento) abandonaram o tratamento. De acordo com a modelo da análise multivariada utilizado, as associações mais significantes para o abandono do tratamento foram o etilismo (com ou sem a concomitância de uso de drogas ilícitas), a infecção por HIV, o fato de o paciente não residir com familiares e o baixo nível de escolaridade. Na análise univariada, indivíduos mais jovens e de etnia não branca também se revelaram significativos para o abandono do tratamento. Gênero e ocorrência de efeitos adversos da medicação não mostraram associação com o abandono. CONCLUSÕES: Na população estudada, alcoolismo, infecção por HIV e o fato de o paciente não residir com familiares foram os fatores preditores mais importantes para o abandono do primeiro tratamento da tuberculose pulmonar.


OBJECTIVE: To determine the predictors of noncompliance with the pulmonary tuberculosis treatment regimen recommended by the Brazilian National Ministry of Health, in previously treatment-naïve patients with active tuberculosis treated in the city of Porto Alegre, Brazil. METHODS: This was a case-control study involving six referral primary health care clinics for tuberculosis in Porto Alegre. We reviewed the medical charts of all previously treatment-naïve patients with active pulmonary tuberculosis who were noncompliant with the treatment between 2004 and 2006. Those were paired with other patients having similar characteristics and having been cured. We conducted univariate and multivariate analyses. RESULTS: Of the 2,098 patients included, 218 (10.4 percent) became noncompliant with the treatment. In the multivariate analysis, the factors most strongly associated with treatment noncompliance were being an alcoholic (with or without concomitant use of illicit drugs), being HIV-infected, not residing with family members, and having a low level of education. In the univariate analysis, treatment noncompliance was also significantly associated with being younger and with being non-White. Gender was not significantly associated with treatment noncompliance; nor was the occurrence of adverse effects of the drugs included in the regimen. CONCLUSIONS: In the population studied, being an alcoholic, being HIV-infected, and not residing with family members were the major predictors of noncompliance with treatment for pulmonary tuberculosis among previously treatment-naïve patients.

RESUMO

This study compared perceptions of the teaching and learning process of twenty-four senior dental students from a public school and fifteen from a private school by means of a questionnaire with direct questions. Another five students in each group completed a qualitative survey with five open-ended questions. The questionnaires assessed perceptions of the interaction between didactic and clinical content, the role of professors during the course, and their future professional practice in Brazil. Quantitative data were summarized as means and standard deviations and statistically analyzed with the Student t test, P<0.05. Qualitative data were analyzed using a content analysis method. The results revealed that the students in the private school had more positive perceptions than those in the public school of how much the didactic classes contributed to professional practice, the level of motivation for the topics discussed, and how well coursework related to clinical practice. Both groups mentioned the importance of the clinical component of learning and perceived that professors showed little commitment to the professional preparation of dental students. Students' perceptions of their preparation to work in different Brazilian communities and with different segments of society varied widely. The qualitative analyses confirmed students' dissatisfaction with their learning. No difference was found between students in the public and private schools in their assessment of how well prepared they were to enter the working market. These findings indicate that measures should be taken to improve the quality of teaching and the satisfaction of dental school students in Brazil.
