Prevalence and Type of HPV Genital Infection in Girls: A Systematic Review and Meta-Analysis.

OBJECTIVES: This investigation explored the prevalence of human papillomavirus (HPV) infection by subtypes in girls aged up to 12. METHODS: Four indexed databases, PubMed, EMBASE, Cochrane, and LILACS, were evaluated. Twenty-nine observational studies published between 1992 and 2018 were included. RESULTS: The prevalence of genital condyloma acuminatum or HPV-positive serology due to prior infection among girls with suspected/confirmed sexual abuse was 25%, and without a history or information about abuse, 8%. The analysis indicated that low-risk HPV types were the most prevalent among this group, corresponding to 86.6% of the identified types. Human papillomavirus 6 and 11 were the most prevalent types, followed by HPV 16 and 2. Moreover, the analysis identified limited epidemiological data on genital warts in children up to 12 years. Several studies focused on convenience sampling, sexually abused girls, or failed to separate data by gender. CONCLUSION: Findings of our systematic review and prevalence meta-analysis indicate that the occurrence of HPV infection in girls aged 12 or younger is relatively rare, underscoring the significance of understanding the prevalence of HPV in the pediatric population. However, it is essential to be cautious when applying these results to the pediatric population, given cases of girls who are suspected of or have suffered sexual abuse. There is a pressing need for further research to fill the information gap on HPV infection in this vulnerable group.

Pooled incidence of continuation and pregnancy rates of four contraceptive methods in young women: a meta-analysis.

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.

Does admission time matter in a paediatric intensive care unit? A prospective cohort study.

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.

Factors Associated With Unplanned Extubation in Children: A Case-Control Study.

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.

Current evidence of contraceptive uptake, pregnancy and continuation rates in young women: a systematic review and Meta-analysis.

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.

Does Tracheal Lidocaine Instillation Reduce Intracranial Pressure Changes After Tracheal Suctioning in Severe Head Trauma? A Prospective, Randomized Crossover Study.

OBJECTIVES: Tracheal suctioning is a routine procedure in mechanically ventilated children, however, in severe head-injured patients it can result in potential deleterious increase in intracranial pressure. We aimed to assess the effect of tracheal lidocaine administration on intracranial pressure during tracheal suctioning. DESIGN: Prospective randomized controlled crossover study. SETTING: PICU of a tertiary hospital. PATIENTS: Eleven patients with severe head trauma (Glasgow Coma Scale score 4-8) INTERVENTIONS:: Lidocaine (1.5 mg/kg) or saline solution was endotracheally instilled before a standardized tracheal suctioning maneuver. Each patient received both treatments in a crossover design. Cerebral hemodynamic and systemic and ventilatory effects were assessed at four time points: in baseline (T0), within 2 minutes (T1), 5 minutes (T2), and 15 minutes after tracheal instillation (T3). The 2-minute time interval around tracheal suctioning was used to assess each treatment efficacy MEASUREMENTS AND MAIN RESULTS:: The time course of intracranial pressure was different throughout the study in both treatment groups, with a significant increase of intracranial pressure from 14.82 ± 3.48 to 23.27 ± 9.06 with lidocaine (p = 0.003) and from 14.73 ± 2.41 to 30.45 ± 13.14 with saline (p = 0.02). The mean variation in intracranial pressure immediately after tracheal suctioning was smaller with lidocaine instillation than saline (8.45 vs 15.72 mm Hg; p = 0.006). Patients treated with lidocaine returned to baseline intracranial pressure value at 5 minutes after tracheal suctioning whereas those receiving saline solution returned to baseline intracranial pressure value at 15 minutes. Although patients treated with lidocaine had no significant hemodynamic changes, patients receiving saline solution experienced a higher mean value of mean arterial pressure (99.36 vs 81.73 mm Hg; p = 0.004) at T1. CONCLUSIONS: This preliminary study showed that tracheal lidocaine instillation can attenuate increase in intracranial pressure induced by tracheal suctioning and favor a faster return to the intracranial pressure baseline levels without significant hemodynamic and ventilatory changes.

Predicting Reintubation After Unplanned Extubations in Children: Art or Science?

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.

Postextubation Dysphagia in Children: The Role of Speech-Language Pathologists.

OBJECTIVES: Postextubation dysphagia is common and associated with worse outcomes in the PICU. Although there has been an increased participation of speech-language pathologists in its treatment, there is limited evidence to support speech-language pathologists as core PICU team member. We aimed to assess the impact of speech-language pathologists interventions on the treatment of postextubation dysphagia. DESIGN: A quasi-experimental prospective study. In the historical group (controls), patients received a standard care management for dysphagia whereas the intervention group was routinely treated by speech-language pathologists. SETTING: PICU of a tertiary hospital. PATIENTS: Children who were endotracheally intubated for a period greater than 24 hours with greater oral intake limitation as defined by a Functional Oral Intake Scale less than or equal to 3. INTERVENTION: Routine speech-language pathologist assessment. MEASUREMENTS AND MAIN RESULTS: A total of 74 patients were enrolled to receive intervention (January 2015 to December 2016) and 41 patients to the historical group (January 2014 to December 2014). There were no differences in the demographic and clinical characteristics. The historical group had both longer time to initiate oral intake (7 vs 4 d; p = 0.0002; hazard ratio, 2.33) and to reach full oral intake compared with intervention group (9 vs 13 d; p < 0.001; hazard ratio, 2.51). A total of 32 controls (78%) and 74 intervention patients (100%) were on total oral intake at discharge (p ≤ 0.001). Three of nine control patients were feeding tube dependent at hospital discharge. Also, controls had a longer length of hospital stay (25 vs 20 d) and a higher rate of reintubation when compared with those patients of intervention group (10% vs 2%). CONCLUSIONS: Incorporating speech-language pathologists in the routine management of postextubation dysphagia can result in faster functional improvement and favorable patient outcomes. Yet, further and larger studies in pediatric dysphagia are required to support the related interventions and strategies to guide clinical practice.

Severe liver and renal injuries following cerebral angiography: late life-threatening complications of non-ionic contrast medium administration.

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.

How the modified Clinical Pulmonary Infection Score can identify treatment failure and avoid overusing antibiotics in ventilator-associated pneumonia.

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.

Impact of Prolonged Continuous Ketamine Infusions in Critically Ill Children: A Prospective Cohort Study.

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.

Use of Machine Perfusion to Increase the Number of Expanded Criteria Deceased Donor Kidney Transplants: A Pharmacoeconomic Analysis.

Background: The discard of expanded criteria donor (ECD) kidneys is unacceptably high, considering the growing demand for transplantation. Using machine perfusion may reduce the discard rate, increase the number of transplants, and reduce mortality on the waiting list. Methods: We developed a 5-y Markov model to simulate incorporating the pulsatile perfusion machine into the current government-funded healthcare system. The model compared the universal use of static cold storage for all kidneys with the selective use of machine perfusion for ECD kidneys. Real-life data were used to compose the cohort characteristics in this model. This pharmacoeconomic analysis aimed to determine the cost-effectiveness and budgetary impact of using machine perfusion to preserve ECD kidneys. Results: Compared with the universal use of static cold storage, the use of machine perfusion for ECD kidneys was associated with an increase in the number of kidney transplants (n = 1123), a decrease in the number of patients on the waiting list (n = 815), and decrease in mortality (n = 120), with a cost difference of US dollar 4 486 009 in the period. The budget impact analysis revealed an additional cost of US dollar 4 453 749 >5 y. The budget impact analysis demonstrated a progressive reduction in costs, becoming cost-saving during the last year of the analysis. Conclusions: This stochastic model showed that incorporating machine perfusion for ECD kidneys is most often a dominant or cost-effective technology associated with an increase in the number of transplants and a reduction in the number of patients on the waiting list, reducing mortality on the waiting list.

Risk factors and outcomes of unplanned PICU postoperative admissions: a nested case-control study.

BACKGROUND: Although unplanned postoperative admission to PICUs (unplanned intensive care admission [UIA]) is uncommon, it might be associated with increased costs, morbidity, and mortality. However, detailed knowledge of risk factors and outcomes after UIA in children is still lacking. OBJECTIVES: To determine prevalence, risk factors, and outcomes of UIA patients compared with non-UIA patients. DESIGN: Case-control study. SETTING: A tertiary university-affiliated hospital. PATIENTS: All postoperative children admitted to the PICU were monitored for UIA. About 28 cases and 88 controls were included. INTERVENTIONS: none. MEASUREMENTS AND MAIN RESULTS: The overall prevalence of UIA was 2.6%. About 28 patients (24.1%) of 116 had unplanned admission. Multiple logistic regression revealed that factors predicting UIA were airway abnormality (odds ratio 16.2, 95% confidence interval 2.65-99.6), anesthetic factors (odds ratio 5.8, 95% confidence interval 1.06-32.2), and hypoxia intraoperative (odds ratio 7.4, 95% confidence interval 1.21-46.24). Procedures on abdomen, emergency surgery, combined anesthesia, and occurrence of intraoperative adverse events were also risk factors for an UIA. Patients with UIA had longer duration of mechanical ventilation than non-UIA patients (4.5 vs. 2 days, p = 0.01), but there were no differences in length of PICU and hospital stays. Preventable adverse events were detected in 25% of UIA children. CONCLUSIONS: Airway abnormality, anesthetic factors, and hypoxia intraoperative were risk factors associated with UIA. Although preventable events contribute significantly to unplanned PICU admissions, they constitute a room of opportunity in quality improvement programs.

The financial impact of neonatal sepsis on the Brazilian Unified Health System.

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.

Mirabegron and Anticholinergics in the Treatment of Overactive Bladder Syndrome: A Meta-analysis.

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.

OBJETIVO: Comparar o uso de mirabegrom com anticolinérgicos para o tratamento da bexiga hiperativa (BH). FONTE DE DADOS: Buscas sistemáticas foram realizadas nas bases de dados EMBASE, PUBMED, Cochrane e LILACS desde o início até setembro de 2021. Incluímos ECR, mulheres com sintomas de BH clinicamente comprovados, estudos que compararam mirabegrom a medicamentos antimuscarínicos e avaliaram a eficácia, segurança ou adesão. COLETA DE DADOS: RevMan 5.4 foi usado para combinar os resultados entre os estudos. Derivamos razões de risco (RRs) e diferenças médias com intervalo de confiança (IC) de 95% usando um modelo meta-analítico de efeitos aleatórios. Cochrane Collaboration Tool e GRADE foi aplicado para risco de viés e qualidade da evidência. SíNTESE DOS DADOS: Foram incluídos 14 estudos com um total de 10.774 pacientes. Menos eventos adversos totais foram relatados no grupo mirabegrom do que no grupo antimuscarínicos [RR: 0,93 (0,89­0,98)]. O risco de distúrbios do trato gastrointestinal e boca seca foram menores com mirabegrom [RR: 0,58 (0,48­0,68); 9.375 pacientes; RR: 0,44 (0,35­0,56), 9.375 pacientes, respectivamente]. Nenhuma diferença foi relatada entre mirabegrom e drogas antimuscarínicos para eficácia. A adesão ao tratamento foi de 87,7% em ambos os grupos [RR: 0,99 (0,98­1,00)]. CONCLUSãO: Mirabegrom e antimuscarínicos têm eficácia e taxas de adesão comparáveis, porém o mirabegrom apresentou menos eventos adversos totais e isolados.

Unplanned endotracheal extubations in the intensive care unit: systematic review, critical appraisal, and evidence-based recommendations.

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.

Additive diuretic response of concurrent aminophylline and furosemide in children: a case series and a brief literature review.

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.

Care bundles to reduce unplanned extubation in critically ill children: a systematic review, critical appraisal and meta-analysis.

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.

A Cost Effectiveness Model of Long-Acting Reversible Contraceptive Methods in the Brazilian National Health System.

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.

Willingness to pay for short- and long-acting contraceptives among female adolescents and their parents in Brazil:a pilot study.

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.
