Survival, Quality of Life, and Functional Status Following Prolonged ICU Stay in Cardiac Surgical Patients: A Systematic Review.

OBJECTIVES: Compared with noncardiac critical illness, critically ill postoperative cardiac surgical patients have different underlying pathophysiologies, are exposed to different processes of care, and thus may experience different outcome trajectories. Our objective was to systematically review the outcomes of cardiac surgical patients requiring prolonged intensive care with respect to survival, residential status, functional recovery, and quality of life in both hospital and long-term follow-up. DATA SOURCES: MEDLINE, Embase, CINAHL, Web of Science, and Dissertations and Theses Global up to July 21, 2017. STUDY SELECTION: Studies were included if they assessed hospital or long-term survival and/or patient-centered outcomes in adult patients with prolonged ICU stays following major cardiac surgery. After screening 10,159 citations, 114 articles were reviewed in full; a final 34 articles met criteria for data extraction. DATA EXTRACTION: Two reviewers independently extracted data and assessed risk of bias using the National Institutes of Health Quality Assessment Tool for Observational Studies. Extracted data included the used definition of prolonged ICU stay, number and characteristics of prolonged ICU stay patients, and any comparator short stay group, length of follow-up, hospital and long-term survival, residential status, patient-centered outcome measure used, and relevant score. DATA SYNTHESIS: The definition of prolonged ICU stay varied from 2 days to greater than 14 days. Twenty-eight studies observed greater in-hospital mortality among all levels of prolonged ICU stay. Twenty-five studies observed greater long-term mortality among all levels of prolonged ICU stay. Multiple tools were used to assess patient-centered outcomes. Long-term health-related quality of life and function was equivalent or worse with prolonged ICU stay. CONCLUSIONS: We found consistent evidence that patients with increases in ICU length of stay beyond 48 hours have significantly increasing risk of hospital and long-term mortality. The significant heterogeneity in exposure and outcome definitions leave us unable to precisely quantify the risk of prolonged ICU stay on mortality and patient-centered outcomes.

Laparoscopic versus open inguinal hernia repair in children: which is the true gold-standard? A systematic review and meta-analysis.

PURPOSE: Hernia repair is one of the most common operations performed in children. Traditionally, an open surgical approach has been utilized; however, laparoscopic repair has been gaining favour within the surgical community. We aimed to determine whether open or laparoscopic hernia repair is optimal for pediatric patients by comparing recurrence rates and other outcomes. METHODS: We searched CENTRAL, MEDLINE, and EMBASE from 1980 onwards, including studies that compared laparoscopic and open repair for pediatric inguinal hernia. RESULTS: Our initial search yielded 345 unique citations. Of these, we reviewed the full text of 28, and included 21 in meta-analysis. The results showed that patients who underwent laparoscopic surgery were more likely to experience wound infection (p = 0.003), but less likely to experience ascending testis (p = 0.05) and metachronous hernia (p = 0.0002). There were no differences in recurrence rates (p = 0.95), surgical time (p = 0.55), length of hospitalization (p = 0.50), intra-operative injury, bleeding, testicular atrophy, or hydrocele. CONCLUSION: Laparoscopic and open surgeries are equivalent in terms of recurrence rates, surgical time, and length of hospitalization. Laparoscopic repair is associated with increased risk of wound infection, but decreased risk of ascending testis. Laparoscopic surgery allows the opportunity to explore and repair the contralateral side, preventing metachronous hernia. LEVEL OF EVIDENCE: III.

Symptom development in originally asymptomatic CPAM diagnosed prenatally: a systematic review.

PURPOSE: For the approximately three quarters of patients with a prenatal diagnosis of congenital pulmonary airway malformation (CPAM) who are asymptomatic at birth, the chance of eventually developing symptoms is unknown. We sought to explore the natural history of asymptomatic CPAM. METHODS: We searched EMBASE, MEDLINE, and the first 50 results from Google Scholar. Studies describing the natural history of prenatally diagnosed, initially asymptomatic CPAM were included. For asymptomatic patients initially managed non-surgically, we tabulated the proportion who went on to develop symptoms as well as the median age at symptom development. RESULTS: We included data from 19 retrospective studies on 353 patients. Of the 128 patients managed expectantly, 31 (24.2%) developed symptoms requiring surgical intervention. The median age at symptom development was 7.5 months (range 15 days-5 years). CONCLUSION: The risk for developing respiratory symptoms exists with originally asymptomatic CPAM patients, but the exact risk is difficult to predict. Parents may be given the value of approximately 1 in 4 as an estimate of the proportion of asymptomatic CPAM patients who go on to develop symptoms, which will help them make an informed decision regarding the option of elective surgery.

One-year symptom trajectories in patients with stable schizophrenia maintained on antipsychotics versus placebo: meta-analysis.

BackgroundAs definitions of relapse differ substantially between studies, in investigations involving data aggregation, total scores on clinical rating scales provide a more generalisable outcome.AimsTo compare total symptom trajectories for antipsychotic versus placebo treatment over a 1-year period of maintenance treatment in schizophrenia.MethodRandomised controlled trials with antipsychotic and placebo treatment arms in patients with stable schizophrenia that reported Positive and Negative Syndrome Scale and Brief Psychiatric Rating Scale total scores at more than one time point were included. Meta-regression analyses were employed using a mixed model.ResultsA total of 11 studies involving 2826 patients were included. Meta-regression analyses revealed significant interactions between group and time (PS<0.0001); both standardised total scores and per cent score changes remained almost unchanged in patients continuing antipsychotic treatment, whereas symptoms continuously worsened over time in those switching to placebo treatment.ConclusionsWhen considering long-term antipsychotic treatment of schizophrenia, clinicians must balance symptomatic and functional outcomes.

What is the optimal surgical strategy for complex perianal fistulous disease in pediatric Crohn's disease? A systematic review.

PURPOSE: Perianal fistulous disease is present in 10-15% of children with Crohn's disease (CD) and is frequently complex and refractory to treatment, with one-third of patients having recurrent lesions. We conducted a systematic review of the literature to examine the best surgical strategy or strategies for pediatric complex perianal fistulous disease (CPFD) in CD. METHODS: We searched CENTRAL, MEDLINE, EMBASE, and CINAHL for studies discussing at least one surgical strategy for the treatment of pediatric CPFD in CD. Reference lists of included studies were hand-searched. Two researchers screened all studies for inclusion, quality assessed each relevant study, and extracted data. RESULTS: One non-randomized prospective and two retrospective studies met our inclusion criteria. Combined use of setons and infliximab therapy shows promise as a first-line treatment. A specific form of fistulectomy, "cone-like resection," also shows promise when combined with biologics. Endoscopic ultrasound to guide medical and surgical management is feasible in the pediatric population, though it is unclear if it improves outcomes. CONCLUSION: There is a paucity of evidence regarding the treatment of CPFD in the pediatric population, and further research is required before recommendations can be made as to what, if any, surgical management is optimal.

Immediate vs Gradual Discontinuation in Antipsychotic Switching: A Systematic Review and Meta-analysis.

Background: Antipsychotic switching is routine in clinical practice, although it remains unclear which is the preferable switching method: immediate discontinuation of the current antipsychotic or a gradual tapering approach. The first strategy has been implicated in rebound/withdrawal symptoms and emergence/exacerbation of symptoms, whereas the gradual approach is thought to pose a risk of additive or synergistic side effects if employed in the context of a crossover approach. Methods: MEDLINE, Embase, and Cochrane Central Register of Controlled Trials were systematically searched. Randomized controlled trials examining immediate vs gradual antipsychotic discontinuation in antipsychotic switching in patients with schizophrenia and/or schizoaffective disorder were selected. Data on clinical outcomes, including study discontinuation, psychopathology, extrapyramidal symptoms, and treatment-emergent adverse events, were extracted. Results: A total of 9 studies involving 1416 patients that met eligibility criteria were included in the meta-analysis. No significant differences in any clinical outcomes were found between the 2 approaches (all Ps > .05). Sensitivity analyses revealed that the findings remained unchanged in the studies where switching to aripiprazole was performed or where immediate initiation of the next antipsychotic was adopted, while some significant differences were observed in switching to olanzapine or ziprasidone. Conclusions: These findings indicate that either immediate or gradual discontinuation of the current antipsychotic medication represents a viable treatment option. Clinicians are advised to choose an antipsychotic switching strategy according to individual patient needs. This said, immediate discontinuation may be advantageous both for simplicity and because a stalled cross-titration process in antipsychotic switching could end up in antipsychotic polypharmacy.
