Systemic lupus erythematosus is associated with an increased frequency of spontaneous preterm births: systematic review and meta-analysis.

OBJECTIVE: Preterm birth is one of the most frequent complications of pregnancy in women with systemic lupus erythematosus. The high indicated preterm birth proportion due to hypertensive disorders of pregnancy and/or fetal growth restriction is well known, and preventive measures and screening for early detection are performed. The risk of spontaneous preterm birth is less well recognized. This study aimed to determine the proportions of spontaneous and indicated preterm birth in pregnancies of women with systemic lupus erythematosus. DATA SOURCES: A systematic literature search using Pubmed, Embase, Web of Science, and Google Scholar was performed in June 2021. STUDY ELIGIBILITY CRITERIA: Studies in pregnant women with systemic lupus erythematosus reporting spontaneous and indicated preterm birth rates were selected. Original research articles published from 1995 to June 2021 were included. METHODS: Quality and risk of bias of the included studies were assessed using the Newcastle-Ottawa quality assessment scale. To estimate the pooled event rates and 95% confidence intervals, meta-analysis of single proportions with a random-effects model was performed. RESULTS: We included 21 articles, containing data of 8157 pregnancies in women with systemic lupus erythematosus. On average, 31% (95% prediction interval, 0.14-0.50) of the pregnancies resulted in preterm birth, including 14% (95% prediction interval, 0.04-0.27) spontaneous and 16% (95% prediction interval, 0.03-0.35) indicated preterm birth. CONCLUSION: In pregnant women with systemic lupus erythematosus, spontaneous and indicated preterm birth proportions are high. This information should be applied in (prepregnancy) counseling and management in pregnancy. The knowledge obtained by this meta-analysis paves the way for further research of associated risk factors and development of interventions to reduce spontaneous preterm birth in systemic lupus erythematosus pregnancies.

Surgery versus sclerotherapy versus combined therapy in head and neck lymphatic malformations in the pediatric population: systematic review and meta-analysis.

PURPOSE: To systematically review current literature on the treatment of lymphatic malformations (LMs) of the head and neck to guide treatment strategy. METHODS AND MATERIALS: A systematic review and meta-analysis of literature until 16 November 2021 was performed on treatments of LMs in the head and neck. RESULTS: Out of 9044 articles, 54 studies were eligible for inclusion with 26 studies providing detailed participant data. A total number of 1573 patients with a mean age of 21.22 months were analysed. Comparative meta-analysis did not reveal significant differences two proportions of volume reduction (≥ 50% and 100%) between sclerotherapy and surgical treatment. Regression demonstrated that positive predictors for volume reduction were surgery 17 (95% CI 0.26-34; p = 0.047) and treatment of macrocystic lesions 19 (95% CI 5.5-32; p = 0.006). Treatment of mixed lesions also demonstrated a trend towards achieving a greater volume reduction (p = 0.052). A higher de Serres stage of the lesion had a negative effect on the amount of volume reduction - 3.7 (95% CI - 7.0 to - 0.35; p = 0.030). CONCLUSION: This comprehensive meta-analysis demonstrated no significant difference in volume reduction between various treatment modalities at study level. However, individual patient data indicated that surgery and larger cyst types are associated with a significant higher percentage of volume reduction, whereas a higher de Serres stage negatively impacted the amount of volume reduction. These findings can be used for patient counseling and treatment planning based on cyst type and de Serres stage. However volume reduction constitutes just one objective within a more complex treatment spectrum.

How do ageism, death anxiety and ageing anxiety among medical students and residents affect their attitude towards medical care for older patients: a systematic review.

BACKGROUND: Although the number of older patients requiring medical care is increasing, caring for older patients is often seen as unattractive by medical trainees (i.e., medical students, residents, interns, and fellows). Terror Management Theory states that people have a negative attitude towards older people, because they remind people of their own mortality. We hypothesize that ageism, death anxiety, and ageing anxiety among medical trainees negatively affect their attitude towards medical care for older patients. This review aimed to examine and generate an overview of available literature on the relationship between ageism, death anxiety, and ageing anxiety among medical trainees and their attitude towards medical care for older patients. METHODS: A systematic review was performed with a review protocol based on the PRISMA Statement. PubMed, Ebsco/PsycInfo, Ebsco/ERIC and Embase were searched from inception to August 2022, using the following search terms, including their synonyms and closely related words: "medical trainees" AND "ageism" OR "death anxiety" OR "ageing anxiety" AND "(attitude AND older patient)". RESULTS: The search yielded 4072 different studies; 12 eligible studies (10 quantitative and 2 qualitative) were identified and synthesized using narrative synthesis. Findings suggest that a positive attitude towards older people was related to a positive attitude towards medical care for older patients among medical students. The available literature on the relationship between death anxiety and/or ageing anxiety and attitude towards medical care for older patients among medical trainees was limited and had a heterogeneity in focus, which hindered comparison of results. CONCLUSION: Our findings suggest that a positive attitude towards older people in general is related to a positive attitude towards medical care for older patients among medical students. Future research should focus on further exploring underlying mechanisms affecting the attitude towards medical care for older patients among medical trainees.

Body composition in preterm infants: a systematic review on measurement methods.

BACKGROUND: There are several methods to measure body composition in preterm infants. Yet, there is no agreement on which method should be preferred. METHODS: PubMed, Embase.com, Wiley/Cochrane Library, and Google Scholar were searched for studies that reported on the predictive value or validity of body composition measurements in preterms, up to 6 months corrected age. RESULTS: Nineteen out of 1884 identified studies were included. Predictive equations based on weight and length indices, body area circumferences, skinfold thickness, bioelectrical impedance, and ultrasound did not show agreement with body composition measured with air displacement plethysmography (ADP), dual-energy x-ray absorptiometry (DXA), magnetic resonance imaging (MRI), or isotope dilution. ADP agreed well with fat mass density measured by isotope dilution (bias -0.002 g/ml, limits of agreement ±0.012 g/ml, n = 14). Fat mass percentage measured with ADP did not agree well with fat mass percentage measured by isotope dilution (limits of agreement up to ±5.8%) and the bias between measurements was up to 2.2%. DXA, MRI, and isotope dilution were not compared to another reference method in preterms. CONCLUSIONS: DXA, ADP, and isotope dilution methods are considered trustworthy validated techniques. Nevertheless, this review showed that these methods may not yield comparable results. IMPACT: Based on validation studies that were conducted in a limited number of study subjects, weight and length indices, body area circumferences, skinfold thickness, bioelectrical impedance, and ultrasound seem to be a poor representation of body composition in preterm infants. DXA, ADP, and isotope dilution methods are considered trustworthy and validated techniques. Nevertheless, these methods may not yield comparable results.

Video-based tools for surgical quality assessment of technical skills in laparoscopic procedures: a systematic review.

BACKGROUND: Quality of surgery has substantial impact on both short- and long-term clinical outcomes. This stresses the need for objective surgical quality assessment (SQA) for education, clinical practice and research purposes. The aim of this systematic review was to provide a comprehensive overview of all video-based objective SQA tools in laparoscopic procedures and their validity to objectively assess surgical performance. METHODS: PubMed, Embase.com and Web of Science were systematically searched by two reviewers to identify all studies focusing on video-based SQA tools of technical skills in laparoscopic surgery performed in a clinical setting. Evidence on validity was evaluated using a modified validation scoring system. RESULTS: Fifty-five studies with a total of 41 video-based SQA tools were identified. These tools were used in 9 different fields of laparoscopic surgery and were divided into 4 categories: the global assessment scale (GAS), the error-based assessment scale (EBAS), the procedure-specific assessment tool (PSAT) and artificial intelligence (AI). The number of studies focusing on these four categories were 21, 6, 31 and 3, respectively. Twelve studies validated the SQA tool with clinical outcomes. In 11 of those studies, a positive association between surgical quality and clinical outcomes was found. CONCLUSION: This systematic review included a total of 41 unique video-based SQA tools to assess surgical technical skills in various domains of laparoscopic surgery. This study suggests that validated SQA tools enable objective assessment of surgical performance with relevance for clinical outcomes, which can be used for training, research and quality improvement programs.

Outcome after vaginal delivery of women with a previous medical history of surgically corrected anorectal malformations: a systematic review.

OBJECTIVE: Discussion remains on how to advise women with a past medical history of surgically corrected anorectal malformations (ARMs) regarding vaginal delivery. The aim of this review is to evaluate and review the reported obstetrical complications and outcomes after vaginal delivery for these women. DATA SOURCES: A systematic search was performed from inception up to 25 July 2022 in PubMed, Embase.com and Clarivate Analytics/Web of Science Core Collection, with backward citation tracking. STUDY ELIGIBILITY CRITERIA/APPRAISAL: All articles reported on the outcomes of interest in women with a past medical history of surgically corrected anorectal malformation and had a vaginal delivery were included with the exception of editorial comments or invitational commentaries. Screening, data extraction and risk of bias assessment was done by two authors independently with a third and fourth reviewer in case of disagreement. Tool for Quality assessment depended on the type of article. As low quality evidence was expected no meta-analysis was performed. RESULTS: Only five of the 2377 articles screened were eligible for inclusion with a total of 13 attempted vaginal deliveries in eight women. In three patients complications were reported: failed vaginal delivery requiring urgent cesarean section in two patients, and vaginal tearing in one patient. CONCLUSION: High quality evidence regarding outcomes and complications after vaginal delivery in women with a history of surgically corrected anorectal malformation is lacking. Therefore, based upon this systematic review no formal recommendation can be formulated regarding its safety. Future studies are essential to address this problem. TRIAL REGISTRATION: CRD42020201390.

Psychosocial work factors affecting mental health of young workers: a systematic review.

OBJECTIVE: For the general working population, robust evidence exists for associations between psychosocial work exposures and mental health. As this relationship is less clear for young workers, this systematic review aims at providing an overview of the evidence concerning psychosocial work factors affecting mental health of young workers. METHODS: The electronic databases used were PubMed, Web of Science, and PsycINFO and were last searched in October 2021. The eligible outcomes included depression-, stress-, burnout- and anxiety-related complaints, and fatigue, excluding clinical diagnoses and suicide-related outcomes. Only studies with workers aged 35 years or younger were included, which reported at least one association between a psychosocial work factor as exposure and a mental health complaint as outcome. Studies had to be in English, German or Dutch. Risk of bias was assessed using an instrument from the National Heart, Lung, and Blood Institute. Data synthesis was conducted using GRADE. RESULTS: In total 17 studies were included in this systematic review, including data from 35,600 young workers in total. Across these studies 86 exposure-outcome associations were reported. Nine exposure-outcome associations could be synthesised. The application of the GRADE framework led to one "low" assessment for the association between psychosocial job quality and mental health. The certainty of evidence for the other eight associations in the synthesis was very low. CONCLUSIONS: The current systematic review disclosed a high degree of uncertainty of the evidence due to conceptually fuzzy outcomes and exposures as well as large heterogeneity between studies.

Impact of sharing Alzheimer's disease biomarkers with individuals without dementia: A systematic review and meta-analysis of empirical data.

INTRODUCTION: We conducted a systematic literature review and meta-analysis of empirical evidence on expected and experienced implications of sharing Alzheimer's disease (AD) biomarker results with individuals without dementia. METHODS: PubMed, Embase, APA PsycInfo, and Web of Science Core Collection were searched according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Results from included studies were synthesized, and quantitative data on psychosocial impact were meta-analyzed using a random-effects model. RESULTS: We included 35 publications. Most personal stakeholders expressed interest in biomarker assessment. Learning negative biomarker results led to relief and sometimes frustration, while positive biomarkers induced anxiety but also clarity. Meta-analysis of five studies including 2012 participants (elevated amyloid = 1324 [66%], asymptomatic = 1855 [92%]) showed short-term psychological impact was not significant (random-effect estimate = 0.10, standard error = 0.23, P = 0.65). Most professional stakeholders valued biomarker testing, although attitudes and practices varied considerably. DISCUSSION: Interest in AD biomarker testing was high and sharing their results did not cause psychological harm. HIGHLIGHTS: Most personal stakeholders expressed interest in Alzheimer's disease biomarker assessment. Personal motivations included gaining insight, improving lifestyle, or preparing for the future. There was no short-term psychological impact of sharing biomarker status, implying it can be safe. Most professional stakeholders valued biomarker testing, believing the benefits outweigh the risk. Harmonized guidelines on biomarker testing and sharing results are required.

The role of vascular smooth muscle cells in the development of aortic aneurysms and dissections.

BACKGROUND: Aortic aneurysms (AA) are pathological dilations of the aorta, associated with an overall mortality rate up to 90% in case of rupture. In addition to dilation, the aortic layers can separate by a tear within the layers, defined as aortic dissections (AD). Vascular smooth muscle cells (vSMC) are the predominant cell type within the aortic wall and dysregulation of vSMC functions contributes to AA and AD development and progression. However, since the exact underlying mechanism is poorly understood, finding potential therapeutic targets for AA and AD is challenging and surgery remains the only treatment option. METHODS: In this review, we summarize current knowledge about vSMC functions within the aortic wall and give an overview of how vSMC functions are altered in AA and AD pathogenesis, organized per anatomical location (abdominal or thoracic aorta). RESULTS: Important functions of vSMC in healthy or diseased conditions are apoptosis, phenotypic switch, extracellular matrix regeneration and degradation, proliferation and contractility. Stressors within the aortic wall, including inflammatory cell infiltration and (epi)genetic changes, modulate vSMC functions and cause disturbance of processes within vSMC, such as changes in TGF-ß signalling and regulatory RNA expression. CONCLUSION: This review underscores a central role of vSMC dysfunction in abdominal and thoracic AA and AD development and progression. Further research focused on vSMC dysfunction in the aortic wall is necessary to find potential targets for noninvasive AA and AD treatment options.

Sexual problems in patients with hematological diseases: a systematic literature review.

PURPOSE: Sexual problems are frequently reported by recipients of hematopoietic stem cell transplantation (HCT). However, little is known about the impact of hematological malignancies and their treatments, without HCT being a part of the treatment regimen. The goal of this systematic review was to examine the prevalence of various sexual problems among patients treated for hematological malignancies without HCT. METHODS: The work focused on online databases available from their inception until 11 November 2020. The data related to sexuality in adult patients diagnosed with hematological malignancies. Selected studies were appraised for methodological quality. RESULTS: Twenty-four studies were included. Twenty-two studies were observational cross-sectional cohort studies, and two studies had a prospective longitudinal design; fourteen studies used non-validated instruments; only two studies used the multidimensional concept of sexuality; six studies compared sexual problems in the target population with reference data. Based on the few high-quality studies, sexual problems occurred in 18-50% of acute leukemia, Hodgkin lymphoma, and non-Hodgkin lymphoma patients. CONCLUSION: Understanding sexual problems in patients treated for hematological malignancies without HCT is not only hampered by the variability in methodology, but also by the lack of research on patients using novel therapies. The exact impact of the diagnosis and treatment of a hematological malignancy on sexual function remains to be answered. Longitudinal studies focusing on the effects of the diagnosis and treatment of hematological malignancies on sexuality using validated questionnaires and comparison with normative data are hugely needed.

A systematic review on mutation markers for bladder cancer diagnosis in urine.

OBJECTIVES: To systematically summarise the available evidence on urinary bladder cancer (BC) mutation markers. Gene mutations are expected to provide novel biomarkers for urinary BC diagnosis. To date, evidence on urinary BC mutation markers has not proven sufficient to be adopted by clinical guidelines. In the present systematic review, diagnostic accuracy of urinary mutation analysis is separately assessed for primary BC diagnosis (BC detection) and for follow-up of BC patients (BC surveillance). METHODS: A literature search (PubMed, Embase.com and Wiley/Cochrane Library) and systematic review was performed up to 31 October 2019. As studies were too heterogeneous, no quantitative analysis could be performed. RESULTS: In total, 25 studies were summarised by qualitative analysis. For BC detection, diagnostic accuracy differed considerably for single mutation markers (sensitivity 1-85%, specificity 84-100%), and for marker panels (sensitivity 50-94%, specificity 43-97%). Similarly, for BC surveillance, diagnostic accuracy was highly variable for single mutation markers (sensitivity 0-85%, specificity 66-100%), and for marker panels (sensitivity 51-84%, specificity 66-96%). CONCLUSION: Urinary mutation analysis showed to be a promising diagnostic tool for non-invasive BC diagnosis. Nonetheless, we observed substantial differences in diagnostic accuracy of urinary BC mutation markers among publications. To translate the data summarised in the present review to future clinical practice, heterogeneity in research design, BC population, mutation analysis technique and urinary DNA should be considered. Eventual clinical implementation of urinary BC mutation markers can only be achieved by collecting more and stronger evidence. Combining different molecular assays might overcome current shortcomings of urinary mutation analysis.

Definitive Chemoradiotherapy Versus Trimodality Therapy for Resectable Oesophageal Carcinoma: Meta-analyses and Systematic Review of Literature.

BACKGROUND: Standard therapy for loco-regionally advanced, resectable oesophageal carcinoma is trimodality therapy (TMT) consisting of neoadjuvant chemoradiotherapy and oesophagectomy. Evidence of survival advantage of TMT over organ-preserving definitive chemoradiotherapy (dCRT) is inconclusive. The aim of this study is to compare survival between TMT and dCRT. METHODS: A systematic review and meta-analyses were conducted. Randomised controlled trials and observational studies on resectable, curatively treated, oesophageal carcinoma patients above 18 years were included. Three online databases were searched for studies comparing TMT with dCRT. Primary outcomes were 1-, 2-, 3- and 5-year overall survival rates. Risk of bias was assessed using the Cochrane risk of bias tools for RCTs and cohort studies. Quality of evidence was evaluated according to Grading of Recommendation Assessment, Development and Evaluation. RESULTS: Thirty-two studies described in 35 articles were included in this systematic review, and 33 were included in the meta-analyses. Two-, three- and five-year overall survival was significantly lower in dCRT compared to TMT, with relative risks (RRs) of 0.69 (95% CI 0.57-0.83), 0.76 (95% CI 0.63-0.92) and 0.57 (95% CI 0.47-0.71), respectively. When only analysing studies with equal patient groups at baseline, no significant differences for 2-, 3- and 5-year overall survival were found with RRs of 0.83 (95% CI 0.62-1.10), 0.81 (95% CI 0.57-1.14) and 0.63 (95% CI 0.36-1.12). CONCLUSION: These meta-analyses do not show clear survival advantage for TMT over dCRT. Only a non-significant trend towards better survival was seen, assuming comparable patient groups at baseline. Non-operative management of oesophageal carcinoma patients might be part of a personalised and tailored treatment approach in future. However, to date hard evidence proving its non-inferiority compared to operative management is lacking.

Is there evidence for the added value and correct use of manual and automatically switching multimemory hearing devices? A scoping review.

OBJECTIVES: To review literature on the use of manual and automatically switching multimemory devices by hearing aid and CI recipients, and to investigate if recipients appreciate and adequately use the ability to switch between programmes in various listening environments. DESIGN: Literature was searched using PubMed, Embase and ISI/Web of Science. Additional studies were identified by screening reference and citation lists, and by contacting experts. STUDY SAMPLE: The search yielded 1109 records that were screened on title and abstract. This resulted in the full-text assessment of 37 articles. RESULTS: Sixteen articles reported on the use of multiple programmes for various listening environments, three articles reported on the use of an automatic switching mode. All studies reported on hearing aid recipients only, no study with CI recipients fulfilled the selection criteria. CONCLUSIONS: Despite the high number of manual and automatically switching multimemory devices sold each year, there are remarkably few studies about the use of multiple programmes or automatic switching modes for various listening environments. No studies were found that examined the accuracy of the use of programmes for specific listening environments. An automatic switching device might be a solution if recipients are not able, or willing, to switch manually between programmes.

Effect of mechanical loading on the metabolic activity of cells in the temporomandibular joint: a systematic review.

OBJECTIVES: The purpose of this systematic review was to elucidate how different modalities and intensities of mechanical loading affect the metabolic activity of cells within the fibro-cartilage of the temporomandibular joint (TMJ). MATERIALS AND METHODS: A systematic review was conducted according to PRISMA guidelines using PubMed, Embase, and Web of Science databases. The articles were selected following a priori formulated inclusion criteria (viz., in vivo and in vitro studies, mechanical loading experiments on TMJ, and the response of the TMJ). A total of 254 records were identified. After removal of duplicates, 234 records were screened by assessing eligibility criteria for inclusion. Forty-nine articles were selected for full-text assessment. Of those, 23 were excluded because they presented high risk of bias or were reviews. Twenty-six experimental studies were included in this systematic review: 15 in vivo studies and 11 in vitro ones. CONCLUSION: The studies showed that dynamic mechanical loading is an important stimulus for mandibular growth and for the homeostasis of TMJ cartilage. When this loading is applied at a low intensity, it prevents breakdown of inflamed cartilage. Yet, frequent overloading at excessive levels induces accelerated cell death and an increased cartilage degradation. CLINICAL SIGNIFICANCE: Knowledge about the way temporomandibular joint (TMJ) fibrocartilage responds to different types and intensities of mechanical loading is important to improve existing treatment protocols of degenerative joint disease of the TMJ, and also to better understand the regenerative pathway of this particular type of cartilage.

Unusual Twinning Resulting in Chimerism: A Systematic Review on Monochorionic Dizygotic Twins.

Traditionally, it is understood that dizygotic (DZ) twins always have a dichorionic placenta. However, with 8% blood chimerism in DZ twins, placental sharing is probably more common than previously has been recognized. In this article, we will review all available cases of monochorionic dizygotic (MCDZ) twins. A total of 31 twins have been described in literature. A monochorionic diamniotic placenta is reported in all cases. Assisted reproductive technology is responsible for the origin of the pregnancy in 82.1% of the cases. In 15.4% of the sex-discordant twins, a genital anomaly was reported in one of the twins. Chimerism is demonstrable in 90.3% of the twins, leading to various diagnostic difficulties. As this review shows that most MCDZ twins are discovered by accident, it can be argued that it is far more common than has been assumed until now. However, the prevalence is still unclear. Awareness of MCDZ twinning is important, with subsequently correct medical strategies. Similarly, the resulting (blood) chimerism is essential to consider in diagnostic procedures, pre- and postnatally. More research on the effect of placental transfusion between sex-discordant twins is required.

Perceptions of residents, medical and nursing students about Interprofessional education: a systematic review of the quantitative and qualitative literature.

BACKGROUND: To identify facilitators and barriers that residents, medical and nursing students perceive in their Interprofessional Education (IPE) in a clinical setting with other healthcare students. METHODS: A systematic review was carried out to identify the perceptions of medical students, residents and nursing students regarding IPE in a clinical setting. PubMed, CINAHL, ERIC and PsycInfo were searched, using keywords and MeSH terms from each database's inception published prior to June 2014. Interprofessional education involving nursing and medical students and/or residents in IPE were selected by the first author. Two authors independently assessed studies for inclusion or exclusion and extracted the data. RESULTS: Sixty-five eligible papers (27 quantitative, 16 qualitative and 22 mixed methods) were identified and synthesized using narrative synthesis. Perceptions and attitudes of residents and students could be categorized into 'Readiness for IPE', 'Barriers to IPE' and 'Facilitators of IPE'. Within each category they work at three levels: individual, process/curricular and cultural/organizational. Readiness for IPE at individual level is higher in females, irrespective of prior healthcare experience. At process level readiness for IPE fluctuates during medical school, at cultural level collaboration is jeopardized when groups interact poorly. Examples of IPE-barriers are at individual level feeling intimidated by doctors, at process level lack of formal assessment and at cultural level exclusion of medical students from interaction by nurses. Examples of IPE-facilitators are at individual level affective crises and patient care crises situations that create feelings of urgency, at process level small group learning activities in an authentic context and at cultural level getting acquainted informally. These results are related to a model for learning and teaching, to illustrate the implications for the design of IPE. CONCLUSIONS: Most of the uncovered barriers are at the cultural level and most of the facilitators are at the process level. Factors at the individual level need more research.

Descriptors for unprofessional behaviours of medical students: a systematic review and categorisation.

BACKGROUND: Developing professionalism is a core task in medical education. Unfortunately, it has remained difficult for educators to identify medical students' unprofessionalism, because, among other reasons, there are no commonly adopted descriptors that can be used to document students' unprofessional behaviour. This study aimed to generate an overview of descriptors for unprofessional behaviour based on research evidence of real-life unprofessional behaviours of medical students. METHODS: A systematic review was conducted searching PubMed, Ebsco/ERIC, Ebsco/PsycINFO and Embase.com from inception to 2016. Articles were reviewed for admitted or witnessed unprofessional behaviours of undergraduate medical students. RESULTS: The search yielded 11,963 different studies, 46 met all inclusion criteria. We found 205 different descriptions of unprofessional behaviours, which were coded into 30 different descriptors, and subsequently classified in four behavioural themes: failure to engage, dishonest behaviour, disrespectful behaviour, and poor self-awareness. CONCLUSIONS: This overview provides a common language to describe medical students' unprofessional behaviour. The framework of descriptors is proposed as a tool for educators to denominate students' unprofessional behaviours. The found behaviours can have various causes, which should be explored in a discussion with the student about personal, interpersonal and/or institutional circumstances in which the behaviour occurred. Explicitly denominating unprofessional behaviour serves two goals: [i] creating a culture in which unprofessional behaviour is acknowledged, [ii] targeting students who need extra guidance. Both are important to avoid unprofessional behaviour among future doctors.

Diagnosis and management of acute appendicitis. EAES consensus development conference 2015.

Unequivocal international guidelines regarding the diagnosis and management of patients with acute appendicitis are lacking. The aim of the consensus meeting 2015 of the EAES was to generate a European guideline based on best available evidence and expert opinions of a panel of EAES members. After a systematic review of the literature by an international group of surgical research fellows, an expert panel with extensive clinical experience in the management of appendicitis discussed statements and recommendations. Statements and recommendations with more than 70 % agreement by the experts were selected for a web survey and the consensus meeting of the EAES in Bucharest in June 2015. EAES members and attendees at the EAES meeting in Bucharest could vote on these statements and recommendations. In the case of more than 70 % agreement, the statement or recommendation was defined as supported by the scientific community. Results from both the web survey and the consensus meeting in Bucharest are presented as percentages. In total, 46 statements and recommendations were selected for the web survey and consensus meeting. More than 232 members and attendees voted on them. In 41 of 46 statements and recommendations, more than 70 % agreement was reached. All 46 statements and recommendations are presented in this paper. They comprise topics regarding the diagnostic work-up, treatment indications, procedural aspects and post-operative care. The consensus meeting produced 46 statements and recommendations on the diagnostic work-up and management of appendicitis. The majority of the EAES members supported these statements. These consensus proceedings provide additional guidance to surgeons and surgical residents providing care to patients with appendicitis.

Laparoscopic Imaging Techniques in Endometriosis Therapy: A Systematic Review.

Endometriosis is a common disease associated with pelvic pain and subfertility. Laparoscopic surgical treatment has proven effective in endometriosis, but is hampered by a high rate of recurrence. The aim of this systematic review was to evaluate the intraoperative identification of endometriosis by enhanced laparoscopic imaging techniques, focusing on sensitivity and specificity. A systematic review was conducted according to PRISMA guidelines in PubMed, Embase, Cochrane Library, and Web of Science. Published prospective studies reporting on enhanced laparoscopic imaging techniques during endometriosis surgery were included. General study characteristics and reported outcomes, including sensitivity and specificity, were extracted. Nine studies were eligible for inclusion. Three techniques were described: 5-ALA fluorescence (5-ALA), autofluorescence (AFI), and narrow-band imaging (NBI). The reported sensitivity of 5-ALA and AFI for identifying endometriosis ranged from 91% to 100%, compared with 48% to 69% for conventional white light laparoscopy (WL). A randomized controlled trial comparing NBI + WL with WL alone reported better sensitivity of NBI (100% vs 79%; p < .001). All 9 studies reported an enhanced detection rate of endometriotic lesions with enhanced imaging techniques. Enhanced imaging techniques are a promising additive for laparoscopic detection and treatment of endometriosis. The 5-ALA, AFI, and NBI intraoperative imaging techniques had a better detection rate for peritoneal endometriosis compared with conventional WL laparoscopy. None of the studies reported clinical data regarding outcomes. Future studies should address long-term results, such as quality of life, recurrence, and need for reoperation.

Autologous Fat Grafting in Cosmetic Breast Augmentation: A Systematic Review on Radiological Safety, Complications, Volume Retention, and Patient/Surgeon Satisfaction.

BACKGROUND: Autologous fat grafting (AFG) is increasingly used in cosmetic surgery. However, its efficacy and safety are still ambiguous. Both a comprehensive overview and recapitulation of the relevant literature provide current evidence on the efficacy and outcomes of AFG in cosmetic breast surgery. OBJECTIVES: This review provides an up-to-date overview of the literature on AFG in cosmetic breast augmentation. METHODS: A systematic review of the literature on AFG used for cosmetic breast augmentation was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. This study included selected studies that were published between January 1996 and February 2016 and reported on 10 patients or more who had a minimal mean follow-up period of 1 year. RESULTS: In this study, 22 articles that reported on 3565 patients with follow-up periods ranging from 12 to 136 months were included. A complication rate of 17.2% (95% CI 15.9-18.5) was seen. Indurations were the most frequent complication (33.3%, 95% CI 20.4-46.3), followed by persistent pain (25%, 95% CI 0.5-49.5), and hematoma (16.4%, 95% CI 14.5-18.4). Mammograms revealed micro-calcifications (9.0%, 95% CI 6.4-11.5) and macro-calcifications (7.0%, 95% CI 3.8-10.2). The mean volume retention was 62.4% (range, 44.7-82.6%), with a satisfaction rate of 92% in patients and 89% in surgeons. CONCLUSIONS: AFG is a promising method in achieving autologous cosmetic breast augmentation with satisfactory volume retention and satisfaction rates in eight and six studies, respectively. Complications and radiological findings are comparable to those after implant augmentation. Future studies should focus on cancer occurrence and detection to further substantiate AFG safety. In addition, grafting methods and the use of auxiliary procedures to identify factors leading to better outcomes in terms of volume retention should be investigated. Finally, objective questionnaires are needed to represent patient satisfaction. LEVEL OF EVIDENCE: 3 Therapeutic.
