title: Traumatic tricuspid valve papillary muscle case with concomitant acquired patent foramen ovale and covert right atrial rupture

description: ABSTRACT Cardiac trauma often occurs in motor vehicle accidents. A 50-year-old female driver was transported to our hospital with multiple trauma after a high-speed car accident. After admission to the intensive care unit, cardiac ultrasound examination revealed traumatic tricuspid valve papillary muscle rupture and patent foramen ovale, while Lancisi's sign was noted on physical examination. Surgical treatment was performed with valve annuloplasty and closure of the patent foramen ovale and a covert right atrial defect that was detected intraoperatively.

title: Intravenous overload of fluids and sodium may contribute to the lower infusion of enteral nutrition in critically ill patients

description: ABSTRACT Objective: To evaluate the effects of intravenous infusion of fluids and sodium on the first day of admission on infusion of enteral nutrition in the first 5 days in intensive care patients. Methods: A prospective cohort study was conducted with critical nonsurgical patients admitted for at least 5 days who were on mechanical ventilation and receiving enteral nutrition. The amount of intravenous fluids and sodium infused on the first day and the volume of enteral nutrition infused in the first 5 days were investigated. The volume of intravenous fluids &gt; 35mL/kg or ≤ 35mL/kg of body weight and sodium (above or below the 25th percentile) infused on the first day was compared with infused enteral nutrition. Results: A total of 86 patients were studied, with a mean (± standard deviation) of 65 ± 17 years, of which 54.7% were female. On the first day, 3,393.7 ± 1,417.0mL of fluid (48.2 ± 23.0mL/kg) and 12.2 ± 5.1g of sodium were administered. Fifty-eight (67.4%) patients received more than 35mL/kg of fluids. In 5 days, 67 ± 19.8% (2,993.8 ± 1,324.4mL) of the prescribed enteral nutrition was received. Patients who received &gt; 35mL/kg of intravenous fluids also received less enteral nutrition in 5 days (2,781.4 ± 1,337.9 versus 3,433.6 ± 1,202.2mL; p = 0.03) versus those who received ≤ 35mL/kg. Patients with intravenous sodium infusion above the 25th percentile (≥ 8.73g) on the first day received less enteral nutrition volume in 5 days (2,827.2 ± 1,398.0 versus 3,509.3 ± 911.9mL; p = 0.02). Conclusion: The results of this study support the assumption that the administration of intravenous fluids &gt; 35mL/kg and sodium ≥ 8.73g on the first day of hospitalization may contribute to the lower infusion of enteral nutrition in critically ill patients.

title: Impact of protein intake and nutritional status on the clinical outcome of critically ill patients

description: ABSTRACT Objective: To evaluate the association of nutritional status and protein intake with the clinical outcomes of critically ill patients receiving enteral nutrition therapy in an intensive care unit. Methods: A retrospective observational analytical study was performed by collecting secondary data recorded in medical records of patients ≥ 18 years of age who were admitted to the intensive care unit and who received exclusive enteral nutrition therapy for at least 72 hours in 2017. Nutritional status was assessed by body mass index and arm circumference. For the estimation of protein requirements, the recommendation of the American Society for Parenteral and Enteral Nutrition was considered. Nutritional adequacy was assessed by the daily collection of prescribed and administered enteral formula. In the analyses, parametric and nonparametric tests were used, and significance was set at p &lt;0.05. Results: Of the 188 patients evaluated, 71.3% were male. The median age of the patients was 48.5 years (31.0 - 63.75). The main clinical diagnosis was trauma (46.3%), and eutrophic was the most frequent nutritional status (54.8% according to body mass index and 46.4% according to arm circumference). Protein adequacy was not attained in 56.4% of patients, and only 46.8% reached the minimum protein recommendation. The occurrence of mortality was associated with nutritional diagnosis, body mass index (p = 0.023), arm circumference (p = 0.041) and protein adequacy (p = 0.012). Conclusion: Nutritional status and protein intake were significantly associated with the clinical outcomes of critically ill patients.

title: Availability of resources to treat sepsis in Brazil: a random sample of Brazilian institutions

description: ABSTRACT Objective: To characterize resource availability from a nationally representative random sample of intensive care units in Brazil. Methods: A structured online survey of participating units in the Sepsis PREvalence Assessment Database (SPREAD) study, a nationwide 1-day point prevalence survey to assess the burden of sepsis in Brazil, was sent to the medical director of each unit. Results: A representative sample of 277 of the 317 invited units responded to the resources survey. Most of the hospitals had fewer than 500 beds (94.6%) with a median of 14 beds in the intensive care unit. Providing care for public-insured patients was the main source of income in two-thirds of the surveyed units. Own microbiology laboratory was not available for 26.8% of the surveyed intensive care units, and 10.5% did not always have access to blood cultures. Broad spectrum antibiotics were not always available in 10.5% of surveyed units, and 21.3% could not always measure lactate within three hours. Those institutions with a high resource availability (158 units, 57%) were usually larger and preferentially served patients from the private health system compared to institutions without high resource availability. Otherwise, those without high resource availability did not always have broad-spectrum antibiotics (24.4%), vasopressors (4.2%) or crystalloids (7.6%). Conclusion: Our study indicates that a relevant number of units cannot perform basic monitoring and therapeutic interventions in septic patients. Our results highlight major opportunities for improvement to adhere to simple but effective interventions in Brazil.

title: Treatment of Resorbed Mandibles with Titanium Plate and Immediate Implant-Supported Prosthesis - Case Series

description: Abstract Severely resorbed mandibles with only cortical bone remaining can fracture during or after implant placement. This case series presents a technique to reduce the risk or the consequences of mandibular fracture. Seven patients with only cortical mandibular bone remaining were treated with the fixation of a titanium plate in the frontal surface previously to implant placement, during the same surgical procedure. Immediate complete-arch implant supported prosthesis were installed. Patient’s systemic and local conditions that could influence implant survival were registered previously to surgery and during the follow up period. Biological and biomechanical complications were recorded. The condition of peri-implant tissues was evaluated. The follow-ups ranged from 12 to 84 months. Twenty-nine implants were placed and no implant failure or other biological complication was observed. The peri-implant tissue evaluation demonstrated most implants was surrounded by keratinized tissue (89.5%). No marginal recession (implant platform cervical to gingival margin) was observed. Probing depth was normal, ranging from 0 to 3 mm. Low scores of plaque index or bleeding on probing were recorded. Biomechanical complications evolved loosening of 4 prosthetic screws and 1 fractured. The use of a titanium plate for the fixation of severely resorbed mandibles with only cortical bone remaining was a safe treatment procedure, avoiding biological and major biomechanical complications in the treatment with immediate complete-arch implant-supported prosthesis.

title: Laryngotracheal separation in pediatric patients: 13-year experience in a reference service

description: ABSTRACT Objective: To evaluate clinical stability of neurologically impaired children and adolescents with recurrent pneumonia submitted to laryngotracheal separation. Methods: Between October 2002 and June 2015, 92 neurologically impaired children from a reference service, with median age of 68.5 months were submitted to laryngotracheal separation. Data were evaluated and statistical analysis was made by Student's t test and Pearson's χ2 test (significance level adopted of 95%). Results: Fifty-three children were male (57.6%). Forty-six children required admission to intensive care, and 42.4% needed mechanical ventilation. We observed that 90.2% of patients were exclusively fed by gastrostomy and 72.4% of the gastrostomies were performed before the tracheal surgery. Thirteen (14.1%) children had postoperative complications as follows: fistulae (5.4%), bleeding (4.3%), granuloma (2.2%) and stenosis (3.2%). A total of 24 patients had pneumonia in the postoperative period (26.1%), but there was a significant drop in occurrence of this condition after surgery (100% versus 26.1%; p&lt;0.001). Twenty-three patients (25%) died. Postoperative complications were similar when comparing patients who died and those that presented good outcome (16.7% versus 13.2%; p=0.73). Conclusion: When well-indicated, the laryngotracheal separation reduces the incidence of postoperative pulmonary infections, thus improving quality of life and reducing admissions to hospital. Laryngotracheal separation should be indicated as a primary procedure in patients with cerebral palsy and recurrent aspiration pneumonia.

title: Influence of Weather on Fire Behavior

description: Abstract Forest fires generate problems at various scales in all ecosystems. It is widely recognized that the more you understand about fire behavior and its response to environmental conditions, the better the decisions about fire management. The objective of this study was to evaluate the behavior of fire and its correlations with environmental factors associated with climate. Controlled burnings of four plots per day, at different times and defined at random, were carried out during 80 days between 07/01/2016 and 11/30/2016. The moisture content was the most important parameter of the flammability of the fuels and the variables of the behavior of the fire. The moisture of the combustible material reflects the atmospheric conditions and can vary more quickly and directly with those of the fire behavior. The air temperature was the most correlated element with the fire intensity although it did not have any correlation with the rate of spread. The variation of the results of this with those of other studies show the importance of understanding fire behavior at the local level.

title: Effect of EDTA and QMIX Ultrasonic Activation on the Reduction of Microorganisms and Endotoxins in Ex Vivo Human Root Canals

description: Abstract The present study aimed to compare the effectiveness of QMiX and 17% EDTA associated to passive ultrasonic irrigation (PUI) or manual agitation (MA) on the reduction of E. faecalis, E. coli and LPS from root canals. Forty single rooted human teeth were randomly divided into four groups (n=10), according to the final irrigation protocol: EDTA+MA, QMiX+MA, EDTA+PUI, QMiX+PUI. Sample collections were obtained from the root canal content immediately before preparation (baseline-S1), after instrumentation (S2), after final irrigation protocol (S3) and 7 days after instrumentation and final irrigation (S4). The antimicrobial effectivity and on endotoxin content were analyzed by culture procedure (CFU/mL) and LAL assay (EU/mL), respectively. The results were statistically analyzed by Kruskal-Wallis and Friedman test (α=5%). QMiX+MA and QMiX+PUI reduced 100% of E. coli and E. faecalis bacteria and also prevented E. faecalisregrowth at S4. EDTA significantly reduced E. coli, but it was not effective in reducing E. faecalis. All protocols reduced EU/mL when compared to S1, however at S4 there was a significant reduction of EU/mL only in the QMiX+MA and QMiX+PUI groups in relation to S3 and S2, respectively. Final irrigation with QMiX associated with MA or PUI had superior antibacterial efficacy compared to EDTA, eliminating 100% of E. coli and E. faecalis strains. In addition, QMiX+PUI reduced 97.61% of the initial content of LPS.
