Reproductive outcomes after surgical treatment of asherman syndrome: A systematic review

In this systematic review, we analysed the reproductive outcomes of hysteroscopic adhesiolysis in women with Asherman syndrome (AS). We searched PubMed, Web of Science and Cochrane Library (from database inception to April 2018) and selected studies that quantitatively described the reproductive outcomes. We assessed study quality and pooled rate data for each outcome.There were 54 studies (4640 women) of varying quality. The pooled rate of pregnancy was 50.7% (95% CI [confidence interval]: 49.1 to 52.3) in 53 studies, early pregnancy loss was 17.7% (95% CI: 15.9 to 19.6) in 31 studies, ectopic pregnancy (EP) was 4.2% (95% CI: 2.8 to 6.3) in 9 studies, mid-trimester loss (MTL) was 11.5% (95% CI: 7.6 to 17.8) in 7 studies, cervical incompetence was 12.5% (95% CI: 3.3 to 33.5) in 2 studies and placenta accreta syndrome was 10.1% (95% CI: 8.6 to 11.8) in 23 studies. The pregnancy rate in women with severe adhesion was significantly lower than that in women with mild adhesion (P = 0.021).These results can be used to counsel women with AS before surgical treatment and for planning antenatal care after conception.     

Does non-surgical periodontal treatment influence on rheumatoid arthritis? A systematic review and meta-analysis

ObjectiveThe objective of this systematic review was to evaluate the efficacy of non-surgical periodontal therapy on rheumatoid arthritis activity.Material and methodsArticles published until April 2019 were electronically searched and screened using PubMed / MEDLINE, Scopus, and Cochrane databases according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PRISMA). This study was recorded in the international PROSPERO database (CRD42019132205). The PICO question (population, intervention, comparison, results) was: in adult patients with rheumatoid arthritis and periodontitis (P), does non-surgical periodontal treatment (I), as compared to no treatment (C), provides better outcomes in rheumatoid arthritis activity (O).ResultsAfter searching the databases, seven articles were selected for qualitative and five for quantitative analysis. The total number of participants included was 292, with an average age of 50.5 years. All patients had rheumatoid arthritis and periodontal disease. Non-surgical periodontal treatment significantly reduced Disease Activity Score 28 (P = 0.004; I² = 92%) and erythrocyte sedimentation rate (P = 0.01; I² = 78%), but with no significant effect on C-reactive protein (P = 0.34; I² = 92%).ConclusionsIt can be concluded that non-surgical periodontal treatment can benefit patients with rheumatoid arthritis.     

Novel point-of-care biomarker combination tests to differentiate acute bacterial from viral respiratory tract infections to guide antibiotic prescribing: a systematic review

BackgroundAcute respiratory tract infections (RTIs) are the most common reason to seek medical care, with many patients receiving inappropriate antibiotics. Novel testing approaches to identify aetiology at the point-of-care are required to accurately guide antibiotic treatment.ObjectiveTo assess the diagnostic accuracy of biomarker combinations to rapidly differentiate between acute bacterial or viral RTI aetiology.Data sourcesMEDLINE, Embase and Web of Science databases were searched to February 2021.Study eligibility criteriaDiagnostic accuracy studies comparing accuracy of point-of-care and rapid diagnostic tests in primary or secondary care, consisting of biomarker combinations, to identify bacterial or viral aetiology of RTI.MethodsRisk of bias was assessed using the QUADAS-2 tool. Sensitivity and specificity of tests reported by more than one study were meta-analysed using a random effects model.ResultsTwenty observational studies (3514 patients) were identified. Eighteen were judged at high risk of bias. For bacterial aetiologies, sensitivity ranged from 61% to 100% and specificity from 18% to 96%. For viral aetiologies, sensitivity ranged from 59% to 97% and specificity from 74% to 100%. Studies evaluating two commercial tests were meta-analysed. For ImmunoXpert, the summary sensitivity and specificity were 85% (95% CI 75%–91%, k = 4) and 86% (95% CI 73%–93%, k = 4) for bacterial infections, and 90% (95% CI 79%–96%, k = 3) and 92% (95% CI 83%–96%, k = 3) for viral infections, respectively. FebriDx had pooled sensitivity and specificity of 84% (95% CI 75%–90%, k = 4) and 93% (95% CI 90%–95%, k = 4) for bacterial infections, and 87% (95% CI 72%–95%; k = 4) and 82% (95% CI 66%–86%, k = 4) for viral infections, respectively.ConclusionCombinations of biomarkers show potential clinical utility in discriminating the aetiology of RTIs. However, the limitations in the evidence base, due to a high proportion of studies with high risk of bias, preclude firm conclusions. Future research should be in primary care and evaluate patient outcomes and cost-effectiveness with experimental study designs.Clinical trialPROSPERO registration number: CRD42020178973.     

Factors contributing to poor sleep in critically ill patients: A systematic review and meta-synthesis of qualitative studies

ObjectiveTo examine the causes of poor sleep in critically ill patients from nurses’ experiences.Review methodologyA meta-synthesis following the Enhancing Transparency in Reporting the Synthesis of Qualitative Research statement was conducted. Articles were searched systematically in the CINAHL, MEDLINE and Embase databases up to January 2020. Study selection and data extraction were performed by two authors working independently. Included articles were critically evaluated by both authors using the Critical Appraisal Screening Programme tool.FindingsThe meta-synthesis resulted in four analytical themes: (1) Inherent factors of critical illness, (2) Lack of implementation of evidence-based practice, (3) Lack of relational collaboration, (4) Hospital organisation and culture.ConclusionThis literature review indicates that promoting critically ill patients' sleep is difficult. Evidence-based interventions should be implemented into practice in order for nurses to be able to meet the patients' needs and improve sleep. Furthermore, the team surrounding the patient must have support from the health care organisation, and a culture change is necessary to improve communication between them to reach a shared goal to improve critically ill patients' sleep.     

Peroperative scoring systems for predicting the outcome of cytoreductive surgery in advanced-stage ovarian cancer – A systematic review

The extent of peritoneal metastases (PM) largely determines the possibility of complete or optimal cytoreductive surgery in advanced ovarian cancer. An objective scoring system to quantify the extent of PM can help clinicians to decide whether or not to embark on CRS. Therefore several scoring systems have been developed by different research teams and this review summarizes their performance in predicting a complete or optimal cytoreduction in patients with advanced ovarian cancer. A systematic search in the MEDLINE database revealed 19 articles that described a total of five main scoring systems to predict the completeness of CRS in patients with FIGO stage III-IV ovarian cancer based on the surgical exploration of the abdominal cavity; PCI, PIV, Eisenkop, Espada, and Kasper. The Peritoneal Cancer Index (PCI) and the Predictive Index Value (PIV) were mentioned most frequently and showed AUCs of 0.69–0.92 and 0.66–0.98, respectively. Due to the use of different cut-offs sensitivities and specificities greatly varied. Therefore with the current data, no scoring system could be identified as best. An objective measure of the extent of disease can be of great clinical use for identifying ovarian cancer patients for which a complete (or optimal) CRS is achievable, however due to local differences in treatment strategies and surgical policy a widely adopted objective scoring system with a standard cut-off value is not feasible. Nevertheless, objective scoring systems can play an important role to guide treatment decisions.     

Systematic information processing style and perseverative worry

This review examines the theoretical rationale for conceiving of systematic information processing as a proximal mechanism for perseverative worry. Systematic processing is characterised by detailed, analytical thought about issue-relevant information, and in this way, is similar to the persistent, detailed processing of information that typifies perseverative worry. We review the key features and determinants of systematic processing, and examine the application of systematic processing to perseverative worry. We argue that systematic processing is a mechanism involved in perseverative worry because (1) systematic processing is more likely to be deployed when individuals feel that they have not reached a satisfactory level of confidence in their judgement and this is similar to the worrier's striving to feel adequately prepared, to have considered every possible negative outcome/detect all potential danger, and to be sure that they will successfully cope with perceived future problems; (2) systematic processing and worry are influenced by similar psychological cognitive states and appraisals; and (3) the functional neuroanatomy underlying systematic processing is located in the same brain regions that are activated during worrying. This proposed mechanism is derived from core psychological processes and offers a number of clinical implications, including the identification of psychological states and appraisals that may benefit from therapeutic interventions for worry-based problems.     

Motor Cortical Excitability Assessed by Transcranial Magnetic Stimulation in Psychiatric Disorders: A Systematic Review

BackgroundTranscranial magnetic stimulation (TMS) is a popular neurostimulation technique suitable for the investigation of inhibitory and facilitatory networks in the human motor system. In the last 20 years, several studies have used TMS to investigate cortical excitability in various psychiatric disorders, leading to a consequent improvement in pathophysiological understanding. However, little is known about the overlap and specificity of these findings across these conditions.ObjectiveTo provide a systematic review of TMS studies (1985–2013) focusing on motor cortical excitability in dementia, schizophrenia, affective disorders (major depression and bipolar), attention deficit hyperactivity disorder (ADHD), obsessive compulsive disorder (OCD), Tourette Syndrome (TS), substance abuse (alcohol, cocaine, cannabis, nicotine) and other disorders (borderline personality disorder, posttraumatic stress disorder (PTSD)).MethodsSystematic literature-based review.ResultsAcross disorders, patients displayed a general pattern of cortical disinhibition, while the most consistent results of reduced short-interval intracortical inhibition could be found in schizophrenia, OCD and Tourette Syndrome. In dementia, the most frequently reported finding was reduced short-latency afferent inhibition as a marker of cholinergic dysfunction.ConclusionsThe results of this systematic review indicate a general alteration in motor cortical inhibition in mental illness, rather than disease-specific changes. Changes in motor cortical excitability provide insight that can advance understanding of the pathophysiology underlying various psychiatric disorders. Further investigations are needed to improve the diagnostic application of these parameters.
