Abstract
BACKGROUND Ketamine has been considered as an adjunct for children who do not reach their predefined target sedation depth. However, there is limited evidence regarding the use of ketamine as a prolonged infusion (i.e., >24 hours) in the pediatric intensive care unit (PICU). OBJECTIVE We sought to evaluate the safety and effectiveness of continuous ketamine infusion for >24 hours in mechanically ventilated children. METHODS We conducted a prospective cohort study in a tertiary PICU from January 2020 to December 2022. The primary outcome was the incidence of adverse events (AEs) after ketamine initiation. The secondary outcome included assessing the median proportion of time the patient spent on the Richmond Agitation-Sedation Scale (RASS) goal after ketamine infusion. Patients were also divided into two groups based on the sedative regimen, ketamine-based or non-ketamine-based, to assess the incidence of delirium. RESULTS A total of 269 patients were enrolled: 73 in the ketamine group and 196 in the non-ketamine group. The median infusion rate of ketamine was 1.4 mg/kg/h. Delirium occurred in 16 (22%) patients with ketamine and 15 (7.6%) patients without ketamine (p = 0.006). After adjusting for covariates, logistic regression showed that delirium was associated with comorbidities (odds ratio [OR] 4.2), neurodevelopmental delay (OR 0.23), fentanyl use (OR 7.35), and ketamine use (OR 4.17). Thirty-one (42%) of the patients experienced at least one AE following ketamine infusion. Other AEs likely related to ketamine were hypertension (n = 4), hypersecretion (n = 14), tachycardia (n = 6), and nystagmus (n = 2). There were no significant changes in hemodynamic variables 24 h after the initiation of ketamine. Regarding the secondary outcomes, patients were at their goal RASS level for a median of 76% (range 68-80.5%) of the time in the 24 hours before ketamine initiation, compared with 84% (range 74.5-90%) of the time during the 24 h after ketamine initiation (p < 0.001). The infusion rate of ketamine did not significantly affect concomitant analgesic and sedative infusions. The ketamine group experienced a longer duration of mechanical ventilation and a longer length of stay in the PICU and hospital than the non-ketamine group. CONCLUSION The use of ketamine infusion in PICU patients may be associated with an increased rate of adverse events, especially delirium. High-quality studies are needed before ketamine can be broadly recommended or adopted earlier in the sedation protocol.

The financial impact of neonatal sepsis on the Brazilian Unified Health System. Clinics (Sao Paulo) 2023; 78:100277. [PMID: 37647843 PMCID: PMC10472220 DOI: 10.1016/j.clinsp.2023.100277] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/24/2022] [Revised: 07/21/2023] [Accepted: 08/08/2023] [Indexed: 09/01/2023] Open
Abstract
OBJECTIVE To evaluate the hospital cost of newborn infants diagnosed with sepsis from the perspective of the Brazilian Public Health System over 11 years. METHOD Cross-sectional study that analyzed secondary data from the databases of the Hospital Information System of the Brazilian Public Health System. Infants hospitalized between 0‒29 days after birth with a diagnosis of sepsis from 2008 to 2018 were included. The diagnosis used in the study was the one that the hospital considered the main diagnosis at admission. Costs were analyzed in US dollars and reflected the amount paid by the Brazilian Public Health System to the hospitals for the informed diagnosis upon admission. The costs were evaluated as the total per admission, and they were compared among Brazilian geographic regions, among etiologic agents, and between neonates with the diagnosis of sepsis that survived or died. RESULTS From 2008 to 2018, 47,554 newborns were hospitalized with sepsis (148.04 cases per 100,000 live births), with an average cost of US$ 3345.59 per hospitalization, ranging from US$ 2970.60 in the North region to US$ 4305.03 in the Midwest. Among sepsis with identified agents, the highest mean cost was related to Gram-negative agents, and the lowest to Streptococcus agalactiae sepsis. Patients with sepsis who died had a higher cost than the survivors (t-test; p = 0.046). CONCLUSIONS The evaluation of costs related to neonatal sepsis in the country during an 11-year period shows the economic impact of morbidity that may be avoided by improving the quality of neonatal care.

Abstract
OBJECTIVE To compare the use of mirabegron with anticholinergics drugs for the treatment of overactive bladder (OB). DATA SOURCE Systematic searches were conducted in EMBASE, PUBMED, Cochrane, and LILACS databases from inception to September 2021. We included RCTs, women with clinically proven OB symptoms, studies that compared mirabegron to antimuscarinic drugs, and that evaluated the efficacy, safety or adherence. DATA COLLECTION RevMan 5.4 was used to combine results across studies. We derived risk ratios (RRs) and mean differences with 95% CIs using a random-effects meta-analytic model. Cochrane Collaboration Tool and GRADE was applied for risk of bias and quality of the evidence. DATA SYNTHESIS We included 14 studies with a total of 10,774 patients. Fewer total adverse events was reported in mirabegron group than in antimuscarinics group [RR 0.93 (0.89-0.98)]. The risk of gastrointestinal tract disorders and dry mouth were lower with mirabegron [RR 0,58 (0.48-0.68); 9375 patients; RR 0.44 (0.35-0.56), 9375 patients, respectively]. No difference was reported between mirabegron and antimuscarinics drugs for efficacy. The adherence to treatment was 87.7% in both groups [RR 0.99 (0.98-1.00)]. CONCLUSION Mirabegron and antimuscarinics have comparable efficacy and adherence rates; however, mirabegron showed fewer total and isolated adverse events.

Care bundles to reduce unplanned extubation in critically ill children: a systematic review, critical appraisal and meta-analysis. Arch Dis Child 2022; 107:271-276. [PMID: 34284999 DOI: 10.1136/archdischild-2021-321996] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/07/2021] [Accepted: 07/05/2021] [Indexed: 01/11/2023]
Abstract
OBJECTIVE To assess the current evidence for the efficacy of care bundles in reducing unplanned extubations (UEs) in critically ill children. DESIGN Systematic review according to the Cochrane guidelines and meta-analysis using random-effects modelling. METHODS We searched MEDLINE, EMBASE, CINAHL, Web of Science, Scopus, Cochrane and SciELO databases from inception until April 2021. We conducted a quality appraisal for each study using the Newcastle-Ottawa Scale and Standards for Quality Improvement Reporting Excellence (SQUIRE) V.2.0 checklist. MAIN OUTCOME The primary outcome measure was UE rates per 100 intubation days. RESULTS We screened 10 091 records and finally included 11 studies. Six studies were pre/post-intervention studies, and five were interrupted time-series studies. The methodological quality was 'good' in 70%, and the remaining as 'fair' (30%). The most frequently used implementation strategies were staff education (100%), root cause analysis (100%), and audit and feedback (82%). Key bundle care components comprised identification of high-risk patients, endotracheal tube care and sedation protocol. Not all studies fully completed the SQUIRE V.2.0 checklist. Meta-analysis revealed a reduction in UE rate following the introduction of care bundles (rate ratio: 0.40 (95% CI: 0.19 to 0.84); p=0.02), which equates to a 60% reduction in UE rates. CONCLUSIONS We found that identifying high-risk patients, endotracheal tube care and protocol-directed sedation are core elements in care bundles for preventing UEs. However, there are several methodological gaps in the literature, including poor evaluation of adherence to bundle components. Future studies should address these gaps to strengthen their validity.

Abstract
INTRODUCTION The use of long-acting reversible contraceptives is low among adolescents owing to the high up-front cost. In this study, a 5-year cost-effectiveness model and budget impact analysis were used to compare the use of long-acting reversible contraceptives with the use of combined oral contraceptives among Brazilian adolescents. METHODS A Markov model was developed to mirror the clinical and economic effects of long-acting reversible contraceptives among sexually active Brazilian adolescents in the public health system for a 5-year duration, starting from 2018. The costs were expressed in U.S.$, and a 5% discount rate was applied for both costs and benefits. Model inputs included costs of the contraceptive methods, contraceptive discontinuation and adherence rates, abortion, and birth costs associated with unintended pregnancies. The model outcomes were avoided pregnancies, abortions, and births. Univariate and probabilistic sensitivity analyses were conducted. RESULTS Copper intrauterine device use was dominant 100% of the time for all outcomes, and a budget impact analysis revealed a cost savings of $422,431,269.10 in the 5-year period. Levonorgestrel intrauterine system and subdermal implant use were cost effective for all outcomes. The budget impact analyses revealed costs of $65,645,417.54 for levonorgestrel intrauterine system and $302,852,972.12 for subdermal implant use during the 5-year study period. CONCLUSIONS According to this Brazilian model, copper intrauterine device use is dominant, and levonorgestrel intrauterine systems and subdermal implants are more cost effective than combined oral contraceptives.

Abstract
OBJECTIVE To analyze the COVID-19 pandemic in Brazil, a continental-sized country, considered as an emerging economy but with several regional nuances, focusing on the availability of human resources, especially for intensive care units. METHODS The database of the National Registry of Health Facilities was accessed. Healthcare professionals in the care of COVID-19 were georeferenced. We correlated the number of professionals with the parameters used by the World Health Organization. According to the Brazilian Intensive Care Medicine Association, we correlated the data for adult intensive care unit beds in each state with the number of professionals for each ten intensive care unit beds. The number of professionals, beds, and cases were then organized by state. RESULTS The number of physicians per 100 thousand inhabitants followed the World Health Organization recommendations; however, the number of nurses did not. The number of intensivists, registered nurses, nurse technicians specialized in intensive care, and respiratory therapists, necessary for every ten intensive care beds, was not enough for any of these professional categories. A complete team of critical care specialists was available for 10% of intensive care unit beds in Brazil. CONCLUSION There is a shortage of professionals for intensive care unit, as we demonstrated for Brazil. Intensive care physical resources to be efficiently used require extremely specialized human resources; therefore, planning human resources is just as crucial as planning physical and structural resources.

Abstract
Objective To evaluate willingness to pay for short- and long-acting reversible contraceptive methods among female Brazilian adolescents and their parents, as well as their perspective on using such methods. Methods This is a cross-sectional study of female adolescents aged 13 to 19 years and their parents. We surveyed to estimate their willingness to pay for contraceptive methods. The values are expressed as mean±standard deviation in Brazilian reals (R$). Spearman correlation was employed for socioeconomic status of parents, age of adolescents and their standpoints. The methods types and adolescent and parent perspectives were analyzed by the test χ2. To determine an agreement between pairs and their willingness to pay, we used the Bland-Altman plot. Results A total of 165 surveys were collected. Short-acting method was significantly more acceptable to pay than the long-action method, by both parents and their daughters. Parents and their daughters are willing to pay out-of-pocket R$ 52,25±22,48 and R$ 51,63±21,24 for short-acting reversible contraception method, and R$ 176,83±130,34 and R$ 174,83±143,64, for long-acting method, respectively. Bland-Altman analysis indicated an agreement on both perspectives and the price they are willing to pay for each contraceptive method. Conclusion Parents and adolescent daughters are more willing to pay for short-acting methods. We showed an agreement between the parent and the daughter for the values paid for each method.

Abstract
BACKGROUND Continuation rates of contraceptive methods in young women vary among studies, and there is scarce data regarding the pregnancy rate in this population. METHODS Four independently systematic searches were performed in PUBMED, EMBASE, LILACS, and Cochrane databases from inception until January 2021 for oral contraceptive pill (OCP), copper IUD, levonorgestrel intrauterine system (LNG-IUS), and subdermal implant. Inclusion criteria were observational or RCT studies that reported continuation for at least 12 months and/or pregnancy rate of these contraceptives methods in girls aged 22 years old or younger. Two authors extracted data from the study design and the outcomes. Pooled proportions of each method were applied using the inverse variance in all calculations with LOGIT transformation, using the random-effects model. Cochrane collaboration tool and New Castle-Ottawa were used to assess the quality and bias of all included studies. GRADE criteria evaluated the quality of evidence. RESULTS Continuation rate for OCP was 51% (95%CI 34%-68%), while for cooper IUD was 77% (95%CI 74%-80%), LNG-IUS 84% (95%CI 80%-87%), and implant 85% (95%CI 81%-88%). The pooled estimated pregnancy rate for OCP was 11% (95%CI 6%-20%), while for cooper IUD was 5% (95%CI 3%-7%), LNG-IUS 1.6% (95%CI 1.2%-2.3%), and implant 1.8% (95%CI 0.4%-8.4%). CONCLUSION Long-acting contraceptive methods presented higher continuation rates and lower pregnancy rates when compared to OCPs.

Abstract
AIM Studies assessing the association between admission time to paediatric intensive care unit (PICU) and mortality are sparse with conflicting results. We aimed to evaluate the impact of time of admission on PICU mortality within 48 h after admission. METHODS This was a single-centre prospective cohort. We collected data from all consecutive children aged 1 month to 16 years over 10 years. RESULTS We included a total of 1368 admissions, with a PICU mortality of 6.6%. Compared with daytime admissions, the overall mortality rate (5.3% vs. 8.5%, P = 0.026) and the mortality within 48 h after admission were higher for those admitted during night-time (2% vs. 4.2%, P = 0.021). There were no differences between mortality rates and the day of admission (weekend admissions vs. weekday admissions). The adjusted odds of death within 48 h after admission was 2.5 (95% confidence interval = 1.22-5.24, P = 0.012) for patients admitted at night-time. A secondary analysis assessing trends in mortality rates during admission showed that the last 5 years of study were more responsible for the chances of death within 48 h (odds ratio = 7.6, 95% confidence interval = 1.91-30.17, P = 0.0039). CONCLUSION Admission to the PICU during night shifts was strongly associated with death compared to daytime admissions. A time analysis of the moment of admission is necessary as a metric of quality of care to identify the interruption or improvement in the continuity of care. Further studies are needed to assess the modified contributing factors.

Abstract
OBJECTIVE Half of all pregnancies worldwide are unintended, and the rate is even higher in women aged ≤25 years. We sought to identify which method of contraception was the most effective option to prevent unintended pregnancy in young women and adolescents. METHODS Systematic searches, without language restrictions, were carried out of the PubMed, Embase, Lilacs and Cochrane databases from inception to July 2020. Abstracts and full-text articles of observational studies and randomised controlled trials comparing the use of multiple methods of long-acting reversible contraception (LARC) and short-acting reversible contraception (SARC) in young women and adolescents were screened and reviewed. Risk ratios (RRs) and mean differences with their 95% confidence interval (CI) were derived using a random-effects meta-analytical model. Meta-analyses provided pooled estimates for adverse events, continuation rates and efficacy of LARC methods in young women and adolescents. Nine of the 25 included studies compared LARC with SARC, and 16 compared LARC methods only. RESULTS At 12 months, young women had better adherence with LARC compared with SARC (n = 1606; RR 1.60; 95% CI 1.21, 2.12; I 2 = 88%), which suggests a better unintended pregnancy prevention outcome for young women. However, more young women chose SARC (n = 2835; RR 0.37; 95% CI 0.17, 0.80; I 2 = 99%). Pregnancy during LARC use was rare. CONCLUSION LARC methods are the most efficacious in preventing pregnancy, and women should be informed of this if pregnancy prevention is their priority. The evidence, however, is of low quality.

Abstract
OBJECTIVE Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is characterized by high contagiousness, as well as variable clinical manifestations and immune responses. The antibody response to SARS-CoV-2 is directly related to viral clearance and the antibodies' ability to neutralize the virus and confer long-term immunity. Nevertheless, the response can also be associated with disease severity and evolution. This study correlated the clinical characteristics of convalescent COVID-19 patients with immunoglobulin A (IgA) and IgG anti-SARS-CoV-2 antibodies. METHODS This study included 51 COVID-19 health care professionals who were candidates for convalescent plasma donation from April to June 2020. The subjects had symptomatic COVID-19 with a polymerase chain reaction-confirmed diagnosis. We measured anti-SARS-CoV-2 IgA and IgG antibodies after symptom recovery, and the subjects were classified as having mild, moderate, or severe symptoms. RESULTS Anti-SARS-CoV-2 antibodies were positive in most patients (90.2%). The antibody indexes for IgA and IgG did not differ significantly between patients presenting with mild or moderate symptoms. However, they were significantly higher in patients with severe symptoms. CONCLUSIONS Our study showed an association between higher antibody indexes and severe COVID-19 cases, and several hypotheses regarding the association of the antibody dynamics and severity of the disease in SARS-CoV-2 infection have been raised, although many questions remain unanswered.

Abstract
It is unknown if the requirement for high dose of vasopressor (HDV) represents a poor outcome in pediatric septic shock. This is a retrospective observational analysis with data obtained from a single center. We evaluated the association between the use of HDV and survival in these patients. A total of 62 children (38 survivors and 24 nonsurvivors) were assessed. The dose of vasopressor (hazard ratio 2.06) and oliguria (hazard ratio 3.17) was independently associated with mortality. The peak of vasopressor was the best prognostic predictor. A cutoff of 1.3 μg/kg/min was associated with mortality with a sensitivity of 75% and specificity of 89%. Vasopressor administration higher than 1.3 μg/kg/min was associated with increased mortality in children with septic shock.

Abstract
Abstract
Background: Obesity is related to major risk factors for a number of noncommunicable diseases including cancer. There is a high incidence of breast and endometrial cancer in obese women. Thus, we performed a systematic review followed by meta-analysis to evaluate the relationship between bariatric surgery, a method widely used to treat obesity, and the risk of developing breast, ovarian and endometrial cancer in obese women.
Methods: MEDLINE, EMBASE, LILACS and Cochrane databases were searched from inception until January 2019 which retrieve studies to assessed the risk of breast, ovarian and endometrial cancer in obese women submitted to bariatric surgery. There was no language restriction. We extracted and combined data from studies in order to assess the risk ratio (RR) of developing these cancers. A random-effects, meta-analytic model was applied in all calculations. The New Castle Ottawa and GRADE were used to assess quality and bias of the included studies. Trial registered in PROSPERO (CRD42019112927).
Results: We found 188 articles and only seven of those were included in our meta-analysis, which incorporated a total of 150,528 patients in the bariatric surgery arm and 1,461,938 women in the control arm. The total risk of developing breast, ovarian and endometrial cancer was 0.37 (95%CI [0.28 to 0.48]; I2=87%; 7 studies). The risk of breast cancer was reduced by 61% [RR: 0.39 (95%CI [0.24 to 0.64]; I2= 90%; 6 studies). The risk of ovarian cancer was reduced by 53% [RR: 0.47 (95%CI [0.27 to 0.81]; I2= 0%; 3 studies). The risk of endometrial cancer was reduced by 67% [RR: 0.33 (95%CI [0.21 to 0.51]; I2= 88%; 7 studies).
Conclusion: Bariatric surgery may have a protective effect by reducing the risk of developing breast, ovarian and endometrial cancer in obese women. However, high heterogeneity was found and not explained by our subgroup analysis. Although we couldn’t separate the types of surgeries performed, we hypothesized that the high heterogeneity might be due to the types of surgery. Therefore, we suggest more research with appropriate report of the type of the surgery by group.

Which children account for repeated admissions within 1 year in a Brazilian pediatric intensive care unit? J Pediatr (Rio J) 2019; 95:559-566.

Abstract
OBJECTIVE While studies have focused on early readmissions or readmissions during the same hospitalization in a pediatric intensive care unit, little is known about the children with recurrent admissions. We sought to assess the characteristics of patients readmitted within 1 year in a Brazilian pediatric intensive care unit. METHODS This was a retrospective study carried out in a tertiary pediatric intensive care unit. The outcome was the maximum number of readmissions experienced by each child within any 365-day interval during a 5-year follow-up period. RESULTS Of the 758 total eligible admissions, 75 patients (9.8%) were readmissions. Those patients accounted for 33% of all pediatric intensive care unit bed care days. Median time to readmission was 73 days for all readmissions. Logistic regression showed that complex chronic conditions (odds ratio 1.07), severe to moderate cognitive disability (odds ratio 1.08), and use of technology assistance (odds ratio 1.17) were associated with readmissions. Multiple admissions had a significantly prolonged duration of mechanical ventilation (8 vs. 6 days), longer length of pediatric intensive care unit (7 vs 4 days) and hospital stays (20 vs 9 days), and higher mortality rate (21.3% vs 5.1%) compared with index admissions. CONCLUSION The rate of pediatric intensive care unit readmissions within 1 year was low; however, it was associated with a relevant number of bed care days and worse outcomes. A 30-day index of readmission may be inadequate to mirror the burden of pediatric intensive care unit readmissions. Patients with complex chronic conditions, poor functional status or technology assistance are at higher risk for readmissions. Future studies should address the impact of qualitative interventions on healthcare and recurrent admissions.

Abstract
OBJECTIVE To compare clinical and surgical outcomes in patients admitted to a gynecological surgery ward before and after the implementation of an evidence-based multimodal and multiprofessional care protocol by the hospital staff. MATERIAL AND METHODS In this historically-controlled cross-sectional study, we compared clinical and surgical outcomes among all women admitted to the gynecological ward of a university public hospital for elective surgery for various reasons before and after the implementation of a multimodal care protocol. The protocol had been implemented to adjust the following procedures to evidence-based recommendations: fluid management/hydration, antimicrobial prophylaxis, management of nausea and vomiting, antithrombotic prophylactic therapy, preoperative fasting, mechanical bowel preparation (reduction), pain management, use of urinary catheters, and stimulus to ambulation. RESULTS After the protocol implementation, fasting time was reduced in approximately 10 h. Patients had to undergo bowel preparation significantly less frequently, and the volume of fluids was reduced too. The use of nausea and vomit prophylaxis increased almost 20 times, but only nausea episodes were reduced. The frequency of antithrombotic prophylactic therapy more than doubled. Hospitalization time decreased significantly. CONCLUSIONS In this study, we observed significant improvements in clinical outcomes after the implementation of a multimodal protocol for perioperative care in the gynecological ward of a public university hospital in Brazil. The protocol implementation was associated with reductions in fasting time, bowel preparation, administration of fluids, pain, nausea and hospitalization time, allowing the treatment of more patients per year in the same ward.

A safety and tolerability profile comparison between dipeptidyl peptidase-4 inhibitors and sulfonylureas in diabetic patients: A systematic review and meta-analysis. Diabetes Res Clin Pract 2019; 149:47-63. [PMID: 30710655 DOI: 10.1016/j.diabres.2019.01.025] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/04/2018] [Revised: 12/14/2018] [Accepted: 01/21/2019] [Indexed: 01/19/2023]
Abstract
BACKGROUND The first treatment approach for type 2 diabetes mellitus is lifestyle change and metformin, but it is usually not sufficient. For some time, the anti-hyperglycemic classes of sulfonylureas and dipeptidyl peptidase-4 (DPP-4) inhibitors were considered second-line of treatment, since they show similar efficacy effect. However, the recent ADA-EASD consensus gives the preference to DPP-4 inhibitors compared to sulfonylureas, except if cost is a major problem. We performed a meta-analysis for safety and tolerability profile to comprehend which treatment has less adverse events. METHODS PUBMED and EMBASE databases were searched from inception until July 2017 to retrieve RCT studies comparing DPP-4 inhibitors and sulfonylureas treatments in adult type 2 diabetes patients. There was no language restriction. We extracted and combined data from studies comparison that reported safety profile and weight change. A random effect, meta-analytic model was applied to all calculations. Cochrane collaboration tool was used to assess quality and bias of the included studies. Trial registered with PROSPERO (CRD42017075823). FINDINGS Out of 1472 articles identified in our search and screened for eligibility, 36 studies comparing DPP-4 inhibitors and sulfonylureas were identified. DPP-4 inhibitors in combination with metformin had less overall adverse events (RR: 0·90; 95% CI, 0·86-0·94; p < 0·0001; I2 = 83%; 17 studies), cardiovascular events (RR: 0·54; 95% CI, 0·37-0·79; p = 0·002; I2 = 0%; 6 studies), hypoglycemia (RR: 0·17; 95% CI, 0·13-0·22; p < 0·00001; I2 = 76%; 17 studies) and severe hypoglycemic events (RR: 0·10; 95% CI, 0·05-0·19; p < 0·00001; I2 = 0%; 12 studies). The mean difference of the weight change was 1·92 kg in favor of DPP-4 inhibitors in combination with metformin in relation to sulfonylureas in combination with metformin. Monotherapy with DPP-4 inhibitors also had less rates of hypoglycemia (RR: 0·31; 95% CI, 0·24-0·41; p < 0·00001; I2 = 0%; 8 studies) and severe hypoglycemic events (RR: 0·26; 95% CI, 0·10-0·66; p = 0·004; I2 = 0%; 8 studies) and patients did not gain 1·19 kg. INTERPRETATION These results suggest better safety profile for DPP-4 inhibitors than sulfonylureas for both comparisons, and it is more notable when the treatment regimen includes metformin. FUNDING This study was funded by Takeda Pharmaceuticals, Brazil.

Abstract
Purpose:Although several studies assess unplanned extubation (UE) in children, few have addressed determinants of UE and factors associated with reintubation in a case-controlled manner. We aimed to identify the risk factors and outcomes associated with UE in a pediatric intensive care unit.Methods:Cases of UE were randomly matched with control patients at a ratio of 1:4 for age, severity of illness, and admission diagnosis. For cases and controls, we also collected data associated with UE events, reintubation, and outcomes.Results:We analyzed 94 UE patients (0.75 UE per 100 intubation days) and found no differences in demographics between the 2 groups. Logistic regression revealed that patient agitation (odds ratio [OR]: 2.44; 95% confidence interval [CI]: 1.28-4.65), continuous sedation infusion (OR: 3.27; 95% CI: 1.70-6.29), night shifts (OR: 9.16; 95% CI: 4.25-19.72), in-charge nurse experience <2 years (OR: 2.38; 95% CI: 1.13-4.99), and oxygenation index (OI) >5 (OR: 76.9; 95% CI: 16.79-352.47) were associated with UE. Risk factors for reintubation after UE included prior level of sedation (COMFORT score < 27; OR: 7.93; 95% CI: 2.30-27.29), copious secretion (OR: 11.88; 95% CI: 2.20-64.05), and OI > 5 (OR: 9.32; 95% CI: 2.45-35.48).Conclusions:This case–control study showed that both patient- and nurse-associated risk factors were related to UE. Risk factors associated with reintubation included lower levels of consciousness, copious secretions, and higher OI. Further evidence-based studies, including a larger sample size, are warranted to identify predisposing factors in UEs.

Abstract
OBJECTIVES: To evaluate the cost effectiveness and economic impact of increasing the use of hypofractionated radiotherapy for the treatment of women older than 50 years, with early breast cancer(stages I and II) within the Brazilian National Health System(SUS).METHODS:Several studies show no difference concerning efficacy and safety between hypofractionated and conventional radiotherapy for the treatment of women older than 50 years with stages I and II disease.We built a cost-effectiveness Markov model in Excel which quantifies the cost and the amount of photon beams linear accelerator time used for the treatment of patients using hypofractionated(2.67Gy/fraction) or conventional(2Gy/fraction).The time horizon is 5 years.The perspective of the study is the SUS.The effectiveness was measured as amount of hours saved using hypofractionated in relation to conventional radiotherapy.Costs related to treatment are from DATASUS,and considered the cost of planning the radiotherapy, of the check-film and the use of photon beams linear accelerator.The discount we applied was 5% for costs and benefits.We performed univariate and probabilistic sensitivity analyses. The treatment fraction time was set as 15 minutes. We also built, in Excel, a budget impact model to simulate the increasing adoption of hypofractionated radiotherapy instead of conventional radiotherapyin the treatment of Brazilian women older than 50 years with early breast cancer.The model compares hypofractionated radiotherapy(2.67Gy/fraction) with conventional radiotherapy(2 Gy/fraction).We determined the number of women over 50 years with stages 1 and 2 breast malignant neoplasm that underwent adjuvant radiotherapy in 2013 and 2014, and then projected these populations for the years 2016 to 2020.We considered the costs of planning the radiotherapy, using the photon beams linear accelerator, and performing the check-film.We considered a yearly increase of 20% in the adoption of hypofractionated radiotherapy for the years 2016 to 2019(2016 20%;2017 40%;2018 60%;2019 80% and 2020 90%).The treatment fraction time was set as 15 minutes. RESULTS: The use of hypofractionated radiotherapy at 5 years was able to decrease the number of hours of treatment(-21,835hours) and the total cost of treatment (-$11,790,229.64).The technology is cost saving.Based on the budget impact analysis, the annual incremental impact would be of -$243,202.65, -$490,294.13, -$741,085.61, -$995,388.73 and -$1,127,712.81 providing 3,378, 6.810, 10,294, 13,826 and 15,664 free hours of the linear accelerator for the years 2016, 2017, 2018, 2019 and 2020, respectively.These photon beams linear accelerator free hours may allow 613, 1,380, 2,306, 3,392 and 4,010 additional patients to have access to breast cancer treatment during the years of 2016 to 2020 respectively. CONCLUSIONS:Considering the conditions proposed in these models increasing the use of hypofractionation as a radiotherapy technique to treat women older than 50 years, with early breast cancer within seems to increase the system efficiency saving money, optimizing the treatment schedule and providing access to treatment for more patients.

Abstract
OBJECTIVE To evaluate the sponsored centers for clinical trial in the respiratory care setting in Brazil: profile; logistics and structure. METHODS Principal investigators (29) and subinvestigators (30) of 39 research centers completed the questionnaires that addressed personal identification and training of researchers, the centers' facilities and advantages and/or disadvantages of performing sponsored trials. RESULTS 75.6% of the centers were located in southern and southeastern Brazil. Most principal investigators were men with a mean age of 53.4 years. The clinical trials in the respiratory care setting focus on asthma and chronic obstructive pulmonar disease (COPD). 80% of the researchers cited delay of the Conep and Anvisa as a barrier to performing research. The advantages of participating in clinical trials were updating knowledge of the researcher and the team, and additional income for the team. The main disadvantages mentioned by the researchers included low financial compensation for the performed workload, and time availability. The median number of professionals per research center was six people, predominantly physicians. CONCLUSION The number of research centers in the respiratory care setting in Brazil is still relatively small. The teams have good training for performing the clinical trials. Asthma and COPD are the most studied diseases in sponsored clinical trials. The main barrier is delay by the Conep and Anvisa. The factors that lead investigators to participate range from being updated along with the team, to site and staff financial issues; the main disadvantage is the low compensation for the required workload demand.

Abstract
PURPOSE Reintubation following unplanned extubation (UE) is often required and associated with increased morbidity; however, knowledge of risk factors leading to reintubation and subsequent outcomes in children is still lacking. We sought to determine the incidence, risk factors, and outcomes related to reintubation after UEs. METHODS All mechanically ventilated children were prospectively tracked for UEs over a 7-year period in a pediatric intensive care unit. For each UE event, data associated with reintubation within 24 hours and outcomes were collected. RESULTS Of 757 intubated patients, 87 UE occurred out of 11 335 intubation days (0.76 UE/100 intubation days), with 57 (65%) requiring reintubation. Most of the UEs that did not require reintubation were already weaning ventilator settings prior to UE (73%). Univariate analysis showed that younger children (<1 year) required reintubation more frequently after an UE. Patients experiencing UE during weaning experienced significantly fewer reintubations, whereas 90% of patients with full mechanical ventilation support required reintubation. Logistic regression revealed that requirement of full ventilator support (odds ratio: 37.5) and a COMFORT score <26 (odds ratio: 5.5) were associated with UE failure. There were no differences between reintubated and nonreintubated patients regarding the length of hospital stay, ventilator-associated pneumonia rate, need for tracheostomy, and mortality. Cardiovascular and respiratory complications were seen in 33% of the reintubations. CONCLUSION The rate of reintubation is high in children experiencing UE. Requirement of full ventilator support and a COMFORT score <26 are associated with reintubation. Prospective research is required to better understand the reintubation decisions and needs.

Abstract
INTRODUCTION Contrast-induced nephropathy requiring dialysis support is rarely reported, whereas severe liver injury after contrast agent administration has not been described in children yet. CLINICAL CASE A previously healthy 10-year-old boy with diagnosis of cerebral arteriovenous malformation underwent a cerebral angiogram study with iohexol (3 mL/kg). After 4 days, he developed vomiting and abdominal pain. Laboratory results showed abnormal liver function tests, including marked elevation of transaminases. In the next day, he evolved with oliguria and blood arterial hypertension. At this time, he presented with worsening renal function tests. Peritoneal dialysis was required for 13 days. The patient had a self-limiting course and received only supportive treatment. CLINICAL PRESENTATION This report highlights delayed complications related to low non-ionic contrast media with a rare presentation that can be neglected or unrecognized by pediatric specialties.

Abstract
Objectives: To evaluate the short and long term effect of hypofractionated radiotherapy on efficacy and safety in women with early stage breast cancer that underwent breast-conserving surgery. Methods: We searched in Embase, Medline, Cochrane Library, and Lilacs for randomized controlled trials comparing conventional unconventional fractioning. Two reviewers obtained data independently and disagreements were solved by consensus. We measured the effect of fractioning within 5 years and after 5 years of treatment by means of the relative risk (RR) obtained from a meta-analytic random effects model comparing unconventional and conventional fractioning in relation to local, loco-regional and distant recurrence, mortality, disease-free survival (number of patients with disease-related events), ischemic heart disease, rib fractures and lung fibrosis. Results: We included five medium/ high quality studies totalizing 7.802 women. Unconventional fractioning does not change within 5 years and after 5 years, respectively: (1) local recurrence RR 0.90 (95% CI 0.68 to 1.18; P = 0.44) and RR 0.98 (95% CI 0.83 to 1.17; P = 0.86); (2) locoregional recurrence RR 0.99 (95% CI 0.71 to 1.36; P = 0.84) and RR 0.97 (95% CI 0.77 to 1.23; P = 0, 79); (3) distant recurrence (RR) 1.04 (95% CI 0.73 to 1.46; P = 0.84) and RR 1.02 (95% CI 0.79 to 1.32; P = 0 , 88); (4) mortality RR 0.89 (95% CI 0.77 to 1.05; P = 0.16) and RR 0.96 (IC 95% from 0.89 to 1.08; P = 0.48); (5) disease-free survival RR 0.96 (95% CI 0.78 to 1.18; P = 0.69) and RR 0.96 (95% CI 0.84 to 1.09, P = 0, 49); (6) cardiac ischemia (radiotherapy in both breasts) RR 0.73 (95% CI 0.34 to 1.57; P = 0.42) and RR 0.61 (95% CI 0.33 to 1.15; P = 0.13); (7) cardiac ischemia (radiotherapy only in the left breast) RR de 0.84 (95% CI; 0.21 to 3,.7; P= 0.80) and RR de 0.72 (95% CI, 0.28 to 1.86; P= 0.49); (8) rib fractures RR 1.02 (95% CI 0.25 to 4.20; P = 0.98) and RR 1.08 (95% CI 0.26 to 4.53; P = 0, 91); (9) pulmonary fibrosis RR 2.42 (95% CI 0.50 to 11.71, P = 0.27) and RR 3.16 (95% CI 0.89 to 11.21, P = 0.07). In a subanalysis, removing the fractioning not recommended by ASTRO, unconventional fractioning increases the occurrence of pulmonary fibrosis after 5 years RR 4.17 (95% CI, 1.05 to 16.56; P = 0.04). In another sub-analysis to verify the possible influence of tumor-bed radiation boost we observed that unconventional fractioning increases disease-free survival within 5 years RR 0.82 (95% CI, 0.69 to 0.97; P = 0.02), decreases distant recurrence after 5 years of the treatment RR 0.80 (95% CI, 0.66 to .96; P = 0.02) but increases the occurrence of pulmonary fibrosis after 5 years RR 4.17 (95% CI, 1.05 to 16.56; P = 0.04). Conclusion: Hypofractioning does not affect, neither in the short nor in the long term, the ocorrence of local, locoregional and distant recurrence, disease-free survival and mortality, of ischemic heart disease, pulmonary fibrosis and ribs fracture in women with early stage breast cancer that underwent breast-conserving surgery.

[PMID: 26133238 DOI: 10.1016/j.jped.2015.03.004] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/28/2015] [Revised: 03/13/2015] [Accepted: 03/13/2015] [Indexed: 11/30/2022] Open
Abstract
OBJECTIVE To estimate the costs of hospitalization in premature infants exposed or not to antenatal corticosteroids (ACS). METHOD Retrospective cohort analysis of premature infants with gestational age of 26-32 weeks without congenital malformations, born between January of 2006 and December of 2009 in a tertiary, public university hospital. Maternal and neonatal demographic data, neonatal morbidities, and hospital inpatient services during the hospitalization were collected. The costs were analyzed using the microcosting technique. RESULTS Of 220 patients that met the inclusion criteria, 211 (96%) charts were reviewed: 170 newborns received at least one dose of antenatal corticosteroid and 41 did not receive the antenatal medication. There was a 14-37% reduction of the different cost components in infants exposed to ACS when the entire population was analyzed, without statistical significance. Regarding premature infants who were discharged alive, there was a 24-47% reduction of the components of the hospital services costs for the ACS group, with a significant decrease in the length of stay in the neonatal intensive care unit (NICU). In very-low birth weight infants, considering only the survivors, ACS promoted a 30-50% reduction of all elements of the costs, with a 36% decrease in the total cost (p=0.008). The survivors with gestational age <30 weeks showed a decrease in the total cost of 38% (p=0.008) and a 49% reduction of NICU length of stay (p=0.011). CONCLUSION ACS reduces the costs of hospitalization of premature infants who are discharged alive, especially those with very low birth weight and <30 weeks of gestational age.

Abstract
BACKGROUND AND OBJECTIVE Benzodiazepines and opioids are commonly used in pediatric intensive care unit. However, there is no previous study assessing the use of administering these drugs combined (single solution) or separately. We sought to evaluate the impact of these 2 different methods of providing sedation/analgesia in pediatric intensive care unit. METHODS One hundred twelve patients mechanically ventilated for more than 48 hours were randomized to receive a protocolized sedation regime comprising midazolam and fentanyl either separately (group 1, 57 patients) or combined as a single solution (group 2, 55 patients). Primary end point variable was the cumulated dose of midazolam and fentanyl. RESULTS The median cumulated doses of both fentanyl (0.19 vs 0.37 mg/kg, P < .05) and midazolam (28.8 vs 45.6 mg/kg, P < .05) required in group 2 were higher when compared with those of group 1. Moreover, group 2 patients had a significantly longer time of vasopressor drugs requirement and a higher number of patients developing tolerance. CONCLUSION Patients who received a single solution of midazolam and fentanyl had a higher cumulated dose of compared with those patients who did not. The potential risk for long-term neurologic effects on developing brains associated with this finding should be considered.

Abstract
OBJECTIVE To analyze the hospital costs and the effectiveness of antenatal corticosteroid (ACS) therapy in a cohort of Brazilian preterm infants. METHODS Infants with gestational age (GA) 26 to 32 weeks, born between 2006 and 2009 in a tertiary university hospital and who survived hospitalization were included. A decision tree was built according to GA (26-27, 28-29, 30-31 and 32 weeks), assuming that each patient exposed or not to ACS may or not develop one of the clinical outcomes included in the model. The cost of each outcome was calculated by microcosting. Sensitivity analysis tested the model stability and calculated outcomes and costs per 1000 patients. RESULTS The cost-effectiveness analysis indicated that ACS reduced USD 3413 in hospital costs per patient exposed to ACS. Its use decreased oxygen dependency at 36 weeks in 11%, advanced resuscitation in delivery room in 24%, severe peri-intraventricular hemorrhage in 12%, patent ductus arteriosus requiring surgery in 3.6% and retinopathy of prematurity in 0.3%, but increased the probability of late-onset sepsis in 2.5%. The sensitivity analysis indicated that ACS was dominant over no ACS therapy for most outcomes. CONCLUSION The results indicate that ACS therapy decreases costs and severe neonatal outcomes of preterm infants.

Abstract
AIM Although the modified Clinical Pulmonary Infection Score (CPIS) has been used to guide treatment decisions in adults with ventilator-associated pneumonia (VAP), paediatric studies are lacking. We assessed a modified CPIS tool to define VAP resolution and identify treatment failure at an early stage. METHODS We identified 70 mechanically ventilated children with VAP according to the Center for Disease Control criteria. Modified CPIS was initially measured at VAP onset and then three and five days afterwards. Children were defined as low risk or high risk based on a cut-off score of six. RESULTS There were 50 high-risk and 20 low-risk patients. Culture results were positive in 64% of the high-risk patients and just 10% of the low-risk patients. Patients on adequate therapy significantly improved their CPIS scores by day three, regardless of the likelihood of VAP. A lack of score improvement demonstrated sensitivity of 100% and specificity of 83% when it came to detecting treatment failure. The area under the receiver operating curve was 0.92. CONCLUSION Serial modified CPIS measurements showed that low-risk patients with negative cultures at day three should be considered for a short course of antibiotics. In contrast, high-risk patients with no score improvement were potentially failing their treatment.

Value of clinical pulmonary infection score in critically ill children as a surrogate for diagnosis of ventilator-associated pneumonia. J Crit Care 2014; 29:545-50.

Abstract
RATIONALE Although the modified clinical pulmonary infection score (mCPIS) has been endorsed by national organizations, only a very few pediatric studies have assessed it for the diagnosis of ventilator-associated pneumonia (VAP). METHODS Seventy children were prospectively included if they fulfilled the diagnosis criteria for VAP referenced by the Centers for Disease Control and Prevention. The primary outcome was performance of mCPIS calculated on day 1 to accurately identify VAP as defined by microbiological data. RESULTS The data showed that an mCPIS of 6 or higher had a sensitivity of 94%, specificity of 50%, positive predictive value of 64%, negative predictive value of 90%, a positive likelihood ratio of 1.88, and a negative likelihood ratio of 0.11. The area under the receiver operating characteristic curve was 0.70. A positive posttest result increased the disease probability by 15.4%, whereas a negative test result reduced the probability by 38.6%. Patients with an mCPIS of 6 or higher had longer length of mechanical ventilation and pediatric intensive care unit stay compared with patients with an mCPIS lower than 6. CONCLUSION The mCPIS had a clinically acceptable performance, and it can be a helpful screening tool for VAP diagnosis. An mCPIS lower than 6 was highly able in distinguishing patients without VAP. Despite its high sensitivity and negative predictive value of this score, further studies are required to assess the use of mCPIS in guiding therapeutic decisions.

Abstract
OBJECTIVE To update the state of knowledge on unplanned extubations (UEs) in neonatal ICUs. This review focuses on the following topics: incidence, risk factors, reintubation after UE, outcomes, and prevention. METHODS The MEDLINE, EMBASE, CINAHL, Scielo, Lilacs, and Cochrane databases were searched for relevant publications from January 1, 1950, through January 30, 2012. Fifteen articles were selected for data abstraction. The search strategy included the following key words: "unplanned extubation," "accidental extubation," "self extubation," "unintentional extubation," "unexpected extubation," "inadvertent extubation," "unintended extubation," "spontaneous extubation," "treatment interference," and "airway accident." Study quality was assessed using the Newcastle-Ottawa scale. Grades of recommendation were assessed according to the Oxford Centre for Evidence-Based Medicine's levels of evidence system. Studies with Newcastle-Ottawa scale score ≥ 5 that included appropriate statistical analysis were deemed of high methodological quality. RESULTS The overall mean Newcastle-Ottawa scale score was 3.5. UE rates ranged from 0.14 to 5.3 UEs/100 intubation days, or 1% to 80.8%. Risk factors included restlessness/agitation (13-89%), poor fixation of endotracheal tube (8.5-31%), tube manipulation at the time of UE (17-30%), and performance of a patient procedure at bedside (27.5-51%). One study showed that every day on mechanical ventilation increased the UE risk 3% (relative risk 1.03, P < .001). The association between birth weight/gestational age and UE is controversial. Reintubation rates ranged from 8.3% to 100%. There is still a gap of information about strategies addressed to reduce the incidence of UE. The best method of endotracheal tube securement remains a controversial issue. CONCLUSIONS Despite numerous publications on UE, there are few studies assessing preventive strategies for adverse events and there is a lack of randomized clinical trials. Recommendations are proposed based on the current available literature.

Abstract
BACKGROUND In this study, we updated the state of knowledge on unplanned tracheal extubations in the intensive care unit. We focused on the following topics: incidence, risk factors, reintubation after unplanned extubation, outcomes, and prevention. Based on this review, recommendations were made for preventing unplanned extubations. METHODS Electronic databases were searched for relevant publications from January 1, 1950 through June 30, 2011 on the MEDLINE, EMBASE, CINAHL, SciELO, LILACS, and Cochrane systems. Fifty articles were eligible for data abstraction. Study quality was assessed using the Newcastle-Ottawa Scale. Grades of recommendation were assessed according to the Oxford Centre for Evidence-Based Medicine. RESULTS Unplanned extubations occur at a rate of 0.1 to 3.6 events per 100 intubation days. Risk factors associated with unplanned extubations included male gender (odds ratio [OR] 4.8), APACHE score ≥17 (OR 9.0), chronic obstructive pulmonary disease, restlessness/agitation (OR 3.3-30.6), lower sedation level (OR 2.0-5.4), higher consciousness level (OR 1.4-2.0), and use of physical restraints (OR 3.1). Reintubation rates ranged from 1.8% to 88% of unplanned extubations. Thirteen studies assessed preventive measures for avoiding unplanned extubations. These studies focused on data collection tools, standardization of procedures, staff education, staff surveillance, and identification and management of high-risk patients. These studies reported reductions in unplanned extubation rate from 22% to 53%. The best methods of securing the endotracheal tube and use of physical restraints remain controversial issues. CONCLUSIONS Despite numerous publications on unplanned extubation, few studies assess preventive strategies for adverse events, and few clinical trials have assessed unplanned extubations. Recommendations are proposed based on the currently available literature.

Abstract
Aminophylline exerts a renovascular effect, acting by adenosine receptor blockade or type IV phosphodiesterase inhibition. Clinically, these drugs have been used with furosemide to induce diuresis in adults and neonates. However, reports on use of aminophylline in diuretic-dependent children are limited to a few studies. We report a case series of four critically ill children unresponsive to furosemide continuous infusion who were subsequently given aminophylline as an adjunct diuretic in the treatment of fluid overload. No side effects were evident. Administration of aminophylline at low doses (3 mg/kg) successfully promoted increased urine output over the 6-h study period in all four children.
