Longitudinal Association between Late-Life Depression (LLD) and Frailty: Findings from a Prospective Cohort Study (MiMiCS-FRAIL).

OBJECTIVES: The aim of the present study was to investigate whether late-life depression (LLD) is associated with incident frailty over time. DESIGN: Prospective cohort study, one-year follow-up. SETTING: Geriatric outpatient clinic, Southwestern of Brazil. PARTICIPANTS: 181 follow-up participants aged 60 years or over. MEASUREMENTS: Depressive disorders were classified as Major Depressive disorder (MDD) or Subthreshold Depression (STD) according to DSM-5 criteria. Depressive symptoms were assessed with validated versions of 15-item Geriatric Depression Scale (GDS-15) and 9-item Patient Health Questionnaire (PHQ-9). We performed binary logistic regressions to estimate the odds ratio (OR) for frailty in LLD adjusting for multiple confounders. Participants who were frail at baseline were excluded from the analyses according to measures of frailty (FRAIL questionnaire and 36-item Frailty Index, FI-36). We also estimated the risk ratio or relative risk (RR) and the risk difference (RD) for incident frailty. RESULTS: We observed a 2 to 4-fold increased risk for incident frailty among participants with LLD. The presence of a depressive disorder was significantly associated with the onset of frailty (adjusted OR for FRAIL and FI-36: 3.07 [95% CI = 1.03 - 9.17] and 3.76 [95% CI = 1.09 - 12.97], respectively. Notably, the risk for frailty due to LLD was significantly higher with the FI-36 compared to the FRAIL (RR: 3.03 versus 2.23). RD was of 17.3% and 12.7% with the FRAIL and the FI-36, respectively. CONCLUSION: Our data support the association between LLD and incident frailty over one year among geriatric outpatients, reinforcing longitudinal evidence from population-based studies.

[Efficacy and safety of nebulized L-epinephrine associated with dexamethasone in postintubation laringitis] / Eficácia e segurança do uso inalatório da adrenalina-L na laringite pós-intubação utilizada em associação com a dexamethasone.

OBJECTIVE: To assess the efficacy and safety of the use of nebulized L-epinephrine associated with dexamethasone in postintubation laryngitis. METHODS: We carried out a prospective, randomized, double-blind, placebo controlled study with two cohorts of patients with postintubation laryngitis graded 3 to 6 by Downes-Raphaelly score during two years. Our population was divided into two groups: A and B; both groups received intravenous dexamethasone and two doses of nebulized saline; however, only group B received L-epinephrine. The efficacy was assessed by Downes-Raphaelly score. The side effects of L-epinephrine were evaluated according to the occurrence of cardiac arrhythmia, increased blood pressure, and average heart rate of group B in comparison to group A. RESULTS: Twenty-two patients were included in group A (average score = 4.8) and 19 in group B (average score = 5.2). During treatment, 3 patients in group A presented a score of 8 and were reintubated. This group also showed higher mean clinical scores than group B during the first two hours of the protocol; these results were not statistically significant. No side effects were observed due to epinephrine. The gas blood measurements were adequate in both groups, but better in the control group. CONCLUSIONS: We did not observe increased efficacy for the treatment of postintubation laryngitis when nebulized L-epinephrine was used simultaneously with intravenous dexamethasone. Some indicators, however, did present a favorable trend when combined therapy was used and should be submitted to further evaluation.

[Therapeutic of septic children with purpuric presentation with two antibiotic schedules] / Terapêutica de crianças com sepse de apresentação purpúrica com dois esquemas antibióticos.

OBJECTIVE: The authors evaluate the therapeutic efficacy of two antibiotic schedules, ceftriaxone alone and the combined use of ampicillin and chloramphenicol, in the treatment of septic children with purpuric presentation.METHODS: A randomized open clinical trial was conducted including septic children with purpuric presentation treated at a pediatric intensive care unit from April 1988 to June 1992. All cases with systemic purpura standing for less than a week were included in one of two groups, except for those recently hospitalized or with previous hemorrhagic disturbs. Patients in group A received ampicillin and chloramphenicol and those in group B were given ceftriaxone. Quantitative parameters were adopted to compare the efficacy of the two antibiotic schedules: sensitivity of bacteria isolated at blood and liquor cultures, complications, therapeutic procedures, period of hospitalization, and sequelae.RESULTS: 19 cases were included in the group A and 16 in group B, both homogenous on clinical-laboratorial aspects. The parameters evaluated did not show different efficacy between the two antimicrobial schedules tested, except for the number of complications observed during hospitalization, which was higher among the children that received ampicillin and chloramphenicol. The overall mortality for the patients treated was 13.8%, excluded the undernourished. CONCLUSIONS: The authors verify similar clinical therapeutic efficacy with the combined use of ampicillin and chloramphenicol or ceftriaxone, as observed previously. It must be pointed that the number of complications detected during hospitalization were higher in the group that received the combined antibiotic schedule. Low mortality in the present study may be attributed to the early diagnosis and therapeutic measures adopted at the pediatric intensive care unit.
