    Research suggests pre-pregnancy obesity is associated with an increased risk of macrosomia in the newborn. Since women are expected to gain weight during pregnancy, the standard recommendation of weight loss for obesity is not ideal for this population. In this systematic review of the literature regarding interventions for maternal obesity to reduce fetal macrosomia, 149 articles were screened using three different databases to identify recent randomized controlled trials related to this topic. A total of 11 full text articles were analyzed and included in the review. The articles addressed nutritional, lifestyle, and pharmacological interventions. The results indicated there is currently insufficient evidence to support specific treatment options for women with obesity during pregnancy to reduce the risk of fetal macrosomia

It was designed to restore teeth in communities without access to conventional dental clinics in poorer countries but has come to be used by dentists in the developed world too, as an alternative to conventional restorative treatment. Objectives: 1) to assess the scope and the methodological and reporting quality of existing systematic reviews of the effectiveness of ART compared to conventional restorative treatment; 2) to evaluate the effectiveness of ART compared to conventional treatment in permanent teeth with class I and II cavities. Methods: Searches: 1) for the assessment of existing systematic reviews: Electronic searches were conducted of OVID Medline, OVID Embase, The Cochrane Database of Systematic Reviews (CDSR), the Centre for Reviews and Dissemination (CRD) databases (DARE, NHSEED and HTA), Google Scholar, and the CNKI and CAOD Chinese databases; 2) for the systematic reviews of ART in permanent teeth: the above searches were supplemented by searches of the Cochrane Central Register of Controlled Trials (CENTRAL), LILAC, BBO, IMEAR (WHO Index Medicus for South East Region), WPRIM (WHO Western Pacific Region Index Medicus) and IndMed, Current Controlled Trials, Clinical Trials, OpenSIGLE, IADR conference abstracts and NLM Gateway. Hand searches were conducted of six dental journals known to have reported ART studies. References from retrieved systematic reviews, trials and other related papers were searched for additional reports. Authors were contacted. There were no language restrictions. Selection criteria: 1) for the assessment of existing systematic reviews: systematic reviews that compared ART to conventional treatment for the restoration of dental cavities; 2) for the systematic reviews of ART in permanent teeth: randomised controlled trials that compared ART using any adhesive material to conventional treatment using amalgam or any adhesive material Data collection: 1) for the assessment of existing systematic reviews: Reviews were selected and data was extracted by a single reviewer using a custom made data extraction sheet. Scope was assessed in terms of materials used, teeth and cavity type. Methodological quality was assessed using AMSTAR. Reporting quality was assessed using the PRISMA guidelines; 2) for the systematic reviews of ART in permanent teeth: reports of trials were screened and selected independently by two reviewers and data would have been extracted on a custom made data extraction sheet had there been eligible trials. Results: 1) for the assessment of existing systematic reviews: three systematic reviews were identified. Two of these were restricted to comparing ART with glass-ionomer to conventional treatment with amalgam; two allowed for inclusion of all cavity types in both deciduous and permanent teeth. None was of high methodological quality and reporting quality was good in one of the reviews only; 2) for the systematic reviews of ART in permanent teeth: no eligible trials were identified. Author’s conclusions: 1) existing systematic reviews do not have sufficient scope to allow for the inclusion of potentially eligible trials that would assess ARTs effectiveness and they have been of high to medium risk of bias; 2) it is disappointing that there are no properly conducted randomised controlled trials comparing ART to conventional treatment in class I and II cavities in the permanent dentition

    This study aimed to assess the economic burden of infection control measures that succeeded in eradicating multidrug-resistant organisms (MDROs) in emerging epidemic contexts in hospital settings. The MEDLINE, EMBASE and Ovid databases were systematically interrogated for original English-language articles detailing costs associated with strict measures to eradicate MDROs published between 1 January 1974 and 2 November 2014. This study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Overall, 13 original articles were retrieved reporting data on several MDROs, including glycopeptide-resistant enterococci (n = 5), carbapenemase-producing Enterobacteriacae (n = 1), methicillin-resistant Staphylococcus aureus (n = 5), and carbapenem-resistant Acinetobacter baumannii (n = 2). Overall, the cost of strict measures to eradicate MDROs ranged from €285 to €57 532 per positive patient. The major component of these overall costs was related to interruption of new admissions, representing €2466 to €47 093 per positive patient (69% of the overall mean cost; range, 13-100%), followed by mean laboratory costs of €628 to €5849 (24%; range, 3.3-56.7%), staff reinforcement costs of €6204 to €148 381 (22%; range, 3.3-52%), and contact precautions costs of €166 to €10 438 per positive patient (18%; range, 0.7-43.3%). Published data on the economic burden of strict measures to eradicate MDROs are limited, heterogeneous, and weakened by several methodological flaws. Novel economic studies should be performed to assess the financial impact of current policies, and to identify the most cost-effective strategies to eradicate emerging MDROs in healthcare facilities

    Assessment of chronic postsurgical pain after knee replacement : a systematic review

    Get PDF
    Objective: Approximately 20% of patients experience chronic pain after total knee replacement (TKR), yet there is no consensus about how best to assess such pain. This systematic review aimed to identify measures used to characterise chronic pain after TKR. Methods: MEDLINE, Embase, PsycINFO, Cochrane Library and CINAHL databases were searched for research articles published in all languages from January 2002- November 2011. Articles were eligible for inclusion if they assessed knee pain at a minimum of 3-months after TKR, yielding a total of 1,164 articles. Data extracted included study design, country, timings of assessments, and outcome measures containing pain items. Outcome measures were compared with domains recommended by IMMPACT for inclusion in assessment of chronic pain related outcomes within clinical trials. Temporal trends were also explored. Results: The review found use of a wide variety of composite and single-item measures, with the American Knee Society Score most common. Many measures used in published studies do not capture the multi-dimensional nature of pain recommended by IMMPACT; of those commonly used, the WOMAC and Oxford Knee Score are most comprehensive. Geographical trends were evident, with nation-specific preferences for particular measures. A recent reduction in use of some clinically-administered tools was accompanied by increased use of patient-reported outcome measures. Conclusion: There was wide variation in methods of pain assessment alongside nation-specific preferences and changing temporal trends in pain assessment after TKR. Standardisation and improvements in assessment is needed to enhance the quality of research and facilitate the establishment of a core outcome set

    Tablets and smart mobile devices are the most recent addition to the long list of technological innovations believed to support and enhance the teaching process and learning process. This review aimed at going beyond the general hype around tablets and smart mobile devices to investigate the evidence supporting their use in educational contexts. To achieve this purpose, a systematic review of quantitative and qualitative research studies published since 2010 was completed. A rigorous review process resulted in the inclusion of 27 quantitative studies that were subjected to a full-scale meta-analytic procedure, and 41 qualitative research studies that were reviewed for substantive study characteristics. A significant average effect size was found for studies comparing tablet use contexts with no tablet use contexts (g+ = 0.23, k = 28). For studies comparing two different uses of tablets by students, the average effect size (g+ = 0.68, k = 12) showed a significant favouring of more student-centred pedagogical use of technology. Although not statistically tested, the findings also indicate that higher effect sizes are achieved when the devices are used with a student-centred approach rather than within teacher-led environments. Similarly, the qualitative literature review revealed that tablets and smart mobile devices are garnering positive perceptions within educational contexts, with the strongest support showing for the technologies’ effectiveness in particular tasks and when used within more student-active contexts. Finally, the review provides an overview of the Turkish Fatih Project as a case study and highlights the lessons learned

    Contextual impacts on industrial processes brought by the digital transformation of manufacturing: a systematic review

    Get PDF
    The digital transformation of manufacturing (a phenomenon also known as "Industry 4.0" or "Smart Manufacturing") is finding a growing interest both at practitioner and academic levels, but is still in its infancy and needs deeper investigation. Even though current and potential advantages of digital manufacturing are remarkable, in terms of improved efficiency, sustainability, customization, and flexibility, only a limited number of companies has already developed ad hoc strategies necessary to achieve a superior performance. Through a systematic review, this study aims at assessing the current state of the art of the academic literature regarding the paradigm shift occurring in the manufacturing settings, in order to provide definitions as well as point out recurring patterns and gaps to be addressed by future research. For the literature search, the most representative keywords, strict criteria, and classification schemes based on authoritative reference studies were used. The final sample of 156 primary publications was analyzed through a systematic coding process to identify theoretical and methodological approaches, together with other significant elements. This analysis allowed a mapping of the literature based on clusters of critical themes to synthesize the developments of different research streams and provide the most representative picture of its current state. Research areas, insights, and gaps resulting from this analysis contributed to create a schematic research agenda, which clearly indicates the space for future evolutions of the state of knowledge in this field

    Left ventricular systolic function evaluated by strain echocardiography and relationship with mortality in patients with severe sepsis or septic shock. a systematic review and meta-analysis

    Get PDF
    Sepsis-induced myocardial dysfunction is associated with poor outcomes, but traditional measurements of systolic function such as left ventricular ejection fraction (LVEF) do not directly correlate with prognosis. Global longitudinal strain (GLS) utilizing speckle-tracking echocardiography (STE) could be a better marker of intrinsic left ventricular (LV) function, reflecting myocardial deformation rather than displacement and volume changes. We sought to investigate the prognostic value of GLS in patients with sepsis and/or septic shock
