RESUMO

BACKGROUND: A growing proportion of patients with early rectal cancer is treated by local excision only. The aim of this study was to evaluate long-term oncological outcomes and the impact of local recurrence on overall survival for surgical local excision in pT1 rectal cancer. METHODS: Patients who only underwent local excision for pT1 rectal cancer between 1997 and 2014 in two Dutch tertiary referral hospitals were included in this retrospective cohort study. The primary outcome was the local recurrence rate. Secondary outcomes were distant recurrence, overall survival and the impact of local recurrence on overall survival. RESULTS: A total of 150 patients (mean age 68.5 ± 10.7 years, 57.3% males) were included in the study. Median length of follow-up was 58.9 months (range 6-176 months). Local recurrence occurred in 22.7% (n = 34) of the patients, with a median time to local recurrence of 11.1 months (range 2.3-82.6 months). The vast majority of local recurrences were located in the lumen. Five-year overall survival was 82.0%, and landmark analyses showed that local recurrence significantly impacted overall survival at 6 and 36 months of follow-up (6 months, p = 0.034, 36 months, p = 0.036). CONCLUSIONS: Local recurrence rates after local excision of early rectal cancer can be substantial and may impact overall survival. Therefore, clinical decision-making should be based on patient- and tumour characteristics and should incorporate patient preferences.

RESUMO

BACKGROUND: Total mesorectal excision (TME) gives excellent oncological results in rectal cancer treatment, but patients may experience functional problems. A novel approach to performing TME is by single-port transanal minimally invasive surgery. This systematic review evaluated the functional outcomes and quality of life after transanal and laparoscopic TME. METHODS: A comprehensive search in PubMed, the Cochrane Library, Embase and the trial registers was conducted in May 2019. PRISMA guidelines were used. Data for meta-analysis were pooled using a random-effects model. RESULTS: A total of 11 660 studies were identified, from which 14 studies and six conference abstracts involving 846 patients (599 transanal TME, 247 laparoscopic TME) were included. A substantial number of patients experienced functional problems consistent with low anterior resection syndrome (LARS). Meta-analysis found no significant difference in major LARS between the two approaches (risk ratio 1·13, 95 per cent c.i. 0·94 to 1·35; P = 0·18). However, major heterogeneity was present in the studies together with poor reporting of functional baseline assessment. CONCLUSION: No differences in function were observed between transanal and laparoscopic TME.


ANTECEDENTES: La escisión total del mesorrecto (total mesorectal excision, TME) proporciona excelentes resultados oncológicos en el tratamiento del cáncer de recto, pero los pacientes pueden presentar trastornos funcionales. Un abordaje novedoso para realizar la TME es mediante cirugía transanal mínimamente invasiva de puerto único. En esta revisión sistemática se evaluaron los resultados funcionales y la calidad de vida después de TME transanal (TaTME) y TME laparoscópica (LapTME). MÉTODOS: En mayo de 2019 se realizó una búsqueda exhaustiva en las bases de datos de Pubmed, Biblioteca Cochrane, EMBASE y en los registros de ensayos clínicos. Se utilizaron las guías PRISMA. Los datos para el metaanálisis se agruparon utilizando un modelo de efectos aleatorios. RESULTADOS: Se identificaron un total de 11.660 estudios, de los cuales se incluyeron 14 estudios y 6 resúmenes de congresos con 846 pacientes (599 TaTME/247 LapTME). Un número sustancial de pacientes presentó trastornos funcionales consistentes con el síndrome de resección anterior baja (low anterior resection syndrome, LARS). El metaanálisis no encontró diferencias significativas en los porcentajes de LARS grave entre los dos abordajes (razón de oportunidades, odds ratio, OR 1,13; i.c. del 95% 0,94-1,35; P = 0,18). Sin embargo, los estudios globalmente presentaron una gran heterogeneidad, así como una deficiente información sobre la evaluación funcional basal. CONCLUSIÓN: No se observaron diferencias en la función entre TaTME y LapTME.

RESUMO

BACKGROUND: The risks of local recurrence and treatment-related morbidity need to be balanced after local excision of early rectal cancer. The aim of this meta-analysis was to determine oncological outcomes after local excision of pT1-2 rectal cancer followed by no additional treatment (NAT), completion total mesorectal excision (cTME) or adjuvant (chemo)radiotherapy (aCRT). METHODS: A systematic search was conducted in PubMed, Embase and the Cochrane Library. The primary outcome was local recurrence. Statistical analysis included calculation of the weighted average of proportions. RESULTS: Some 73 studies comprising 4674 patients were included in the analysis. Sixty-two evaluated NAT, 13 cTME and 28 aCRT. The local recurrence rate for NAT among low-risk pT1 tumours was 6·7 (95 per cent c.i. 4·8 to 9·3) per cent. There were no local recurrences of low-risk pT1 tumours after cTME or aCRT. The local recurrence rate for high-risk pT1 tumours was 13·6 (8·0 to 22·0) per cent for local excision only, 4·1 (1·7 to 9·4) per cent for cTME and 3·9 (2·0 to 7·5) per cent for aCRT. Local recurrence rates for pT2 tumours were 28·9 (22·3 to 36·4) per cent with NAT, 4 (1 to 13) per cent after cTME and 14·7 (11·2 to 19·0) per cent after aCRT. CONCLUSION: There is a substantial risk of local recurrence in patients who receive no additional treatment after local excision, especially those with high-risk pT1 and pT2 rectal cancer. The lowest recurrence risk is provided by cTME; aCRT has outcomes comparable to those of cTME for high-risk pT1 tumours, but shows a higher risk for pT2 tumours.


ANTECEDENTES: Tras una resección temprana de un cáncer de recto localizado, hay que considerar el equilibrio entre el riesgo de recidiva local y la morbilidad relacionada con el tratamiento. El objetivo de este metaanálisis era determinar los resultados oncológicos tras la resección de un cáncer de recto pT1-T2 seguida de ningún tratamiento adicional (no additional treatment, NAT), escisión total del mesorrecto (completion total mesorectal excision, cTME) o quimiorradioterapia adyuvante (adjuvant chemoradiotherapy, aCRT). METHODS: Se llevó a cabo una búsqueda sistemática en PubMed, Embase y biblioteca Cochrane. La variable principal de resultado era la recidiva local (local recurrence, LR). En el análisis estadístico se calcularon las medias ponderadas de proporciones. RESULTADOS: Se incluyeron en el análisis 76 estudios con un total de 4.793 pacientes. NAT fue evaluada en 72 estudios, cTME en 13 y aCRT en 28. La tasa de LR para NAT en tumores pT1 de bajo riesgo era de 6,7% (i.c. del 95% 4,8-9,3). No se observaron casos de LR en tumores pT1 de bajo riesgo tras cTME o aCRT. La tasa de LR para tumores pT1 de alto riesgo fue de 13,6% (i.c. del 95% 8,0-22,0) para la resección local como único tratamiento, 4,1% (i.c. del 95% 1,7-9,4) para cTME y 3,9% (i.c. del 95% 2,0-7,5) para aCRT. La tasa de LR para tumores pT2 fue de 28,9% (i.c. del 95% 22,3-36,4) para NAT, 4,3% (i.c. del 95% 1,4-12,5) para cTME y 14,7% (i.c. del 95% 11,2-19,0) para aCRT. CONCLUSIÓN: Tras la resección local de cáncer pT1 de alto riesgo y pT2, existe un riesgo sustancial de recidiva local en ausencia de tratamiento adicional. La escisión total del mesorrecto se asocia con el menor riesgo de recidiva. La quimiorradioterapia adyuvante ofrece resultados similares a la escisión total del mesorrecto en tumores pT1 de alto riesgo, pero presenta un mayor riesgo en tumores pT2.

RESUMO

STUDY QUESTION: Is embryo culture media used during an IVF/ICSI treatment associated with differences in growth, body composition and cardiovascular development as determined in 9-year-old singleton IVF children? SUMMARY ANSWER: The choice of in vitro culture medium for human embryos is associated with differences in body weight, BMI, truncal adiposity, waist circumference and waist/hip ratio at the age of 9, while no significant differences were observed in cardiovascular development. WHAT IS KNOWN ALREADY: Children born after IVF/ICSI have an increased risk of low birthweight, which is correlated with a higher risk of cardiovascular diseases. Some studies show that IVF children exhibit a significantly higher systolic and diastolic blood pressure and higher fasting glucose levels compared to naturally conceived children. After alternating assignment to G1™ Version 3 (Vitrolife) or K-SICM (Cook) embryo culture media, birthweight of the resulting children was significantly higher in the Vitrolife group and they remained heavier during the first 2 years of life. STUDY DESIGN, SIZE, DURATION: In this observational cohort study (MEDIUM-KIDS), parents of singletons from a previous study were approached for further follow-up after the ninth birthday of their child. The singletons were born after fresh embryo transfer of cleavage stage embryos resulting from an IVF/ICSI treatment performed between July 2003 and December 2006 in our clinic, when two different culture media were used alternately: either G1™ Version 3 (Vitrolife) or K-SICM (Cook). Follow-up measurements were performed between March 2014 and December 2016. PARTICIPANT/MATERIALS, SETTINGS, METHODS: Parents were invited to attend our clinic with their child for a single visit lasting ~2.5 h. Two experienced clinicians performed all measurements as part of the MEDIUM-KIDS study in a standardized way. Height and weight of the child was measured using calibrated scales, 4-point skinfold thickness measurements were measured in triplicate and waist and hip circumference were measured using a tape measure. The following cardiovascular parameters were measured in a standardized way: blood pressure, heart rate and endothelial function by skin laser-Doppler with iontophoresis using vasodilatory drugs. Cortisol and cortisone concentrations in hair were measured. A blood sample was taken after an overnight fast for insulin, glucose, TSH and lipid analysis. Blood samples of the IVF children were compared with a non-IVF control group. Differences between culture medium groups were analysed by Student's t-test and effects of confounders were analysed using multivariable regression analysis. MAIN RESULTS AND THE ROLE OF CHANCE: Of the 294 eligible children (168 Vitrolife and 126 Cook), 136 children (75 Vitrolife and 61 Cook) participated in the study. Baseline characteristics of the participating children from the Vitrolife and Cook group were similar. Birthweight was higher in the Vitrolife group, in keeping with the full cohort. After correction for confounders, the difference in weight and BMI attributable to culture medium was 1.58 kg (95% CI: 0.01-3.14) and 0.84 kg/m2 (95% CI: 0.02-1.67), respectively, with the Vitrolife children being heavier. Height and height corrected for age and gender (SDS scores) were similar in both groups. Furthermore, waist circumference was significantly higher in the Vitrolife group with a corrected difference of 3.21 cm (95%CI: 0.60-5.81) leading to a 0.03 increase (95% CI: 0.01-0.05) in waist/hip ratio. Subscapular skinfolds combined with suprailiacal skinfolds (defined as truncal adiposity), was also significantly higher in Vitrolife children (adjusted difference 3.44 cm [95% CI: 0.27-6.62]). Both systolic (adj. beta 0.364 [95% CI: -2.129 to 2.856],) and diastolic (adj. beta 0.275 [95% CI: -2.105 to 2.654]) blood pressures (mmHg) were comparable for the two groups. After an overnight fast, cholesterol, glucose, insulin, low and high-density lipoprotein, triglycerides and TSH were normal and similar in the two groups. Endothelial function in the microcirculation was compared by using maximum perfusion units corrected for the baseline value as a measure for vasodilatory capacity. There were no significant differences between the two groups. Cortisol and cortisone concentration in hair samples were comparable. LIMITATIONS, REASONS FOR CAUTION: A limitation of the original study was its pseudo-randomized design. This and the dwindling enthusiasm of families for participation (47.7% after 9 years) prevent us from drawing robust causal conclusions from the observed association. Nevertheless, to date this is oldest cohort of IVF/ICSI children where culture medium was allocated alternatingly and used in a blinded setting, to be studied. We believe that our participants are representative for the full cohort. The current number of participants was sufficient to rule out differences as little as 3 mmHg in systolic and diastolic blood pressures. WIDER IMPLICATIONS OF THE FINDINGS: This study underlines the importance of structured follow-up of IVF/ICSI children to further elucidate possible long-term health effects. Health professionals and culture medium manufacturers should be aware that small changes in culture conditions and culture medium composition for the early embryo can have long-term health effects. The similar cardiovascular results for the two groups are reassuring but the children may still be too young to detect differences in cardiovascular development. Prolonged follow-up and structured investigations up until adulthood are necessary to gain more insight and reassurance in the cardiovascular development of IVF offspring, although long-term follow-up will become more complicated by confounding life-style and environmental factors possibly influencing development. STUDY FUNDING/COMPETING INTEREST(S): The study was financially supported by the March of Dimes (Grant number #6-FY13-153). The sponsor of the study had no role in study design, data collection, data analysis, data interpretation or writing of the report. The authors have no conflicts of interest to declare. TRIAL REGISTRATION NUMBER: NTR4220.

RESUMO

STUDY QUESTION: To what extent are endometriosis and its related physical and mental symptoms associated with the perceived level of sexual functioning in women and their male partners? SUMMARY ANSWER: Dyspareunia and depressive symptoms are associated with impaired sexual functioning in women with endometriosis, whereas sexual functioning in their male partners is not affected. WHAT IS KNOWN ALREADY: Women with endometriosis suffer from more dyspareunia, lower sexual functioning, and lower quality of life. In qualitative studies, partners of women with endometriosis report that endometriosis affected their quality of life and produced relational distress. STUDY DESIGN SIZE, DURATION: In this cross-sectional study, sexual functioning in women with endometriosis (n = 83) and their partners (n = 74) was compared with sexual functioning in a control group of women attending the outpatient department for issues related to contraception (n = 40), and their partners (n = 26). PARTICIPANTS/MATERIALS, SETTING, METHODS: Women and partners were recruited in the Maastricht University Medical Centre (MUMC) and the VieCuri Medical Centre Venlo between June 2011 and December 2012. All participants were asked to complete a set of online questionnaires. MAIN RESULTS AND THE ROLE OF CHANCE: Response rates were 59.3% (83/140) for women with endometriosis and 52.3% (74/140) for their partners. Response rates in the control group were respectively 43.2% and 27.4% (41/95 and 27/95), of whom 40 women and 26 partners could be included in the study. Women with endometriosis as compared with the control group, reported significantly more frequent pain during intercourse (53% versus 15%, P < 0.001); higher levels of chronic pain (median VAS 2.0 cm versus 0.0 cm, P < 0.001); more impairment of sexual functioning (median Female Sexual Function Index 25.4 versus 30.6, P < 0.001); more impairment of quality of life (median Short Form-12 66.3 versus 87.2, P < 0.001); more pain catastrophizing (mean Pain Catastrophizing Scale 17.8 versus 8.5, P < 0.001), more depression and anxiety symptoms (median Hospital Anxiety and Depression Scale for depression 7 versus 4, P < 0.001 and for anxiety 4 versus 1, P < 0.001). Sexual functioning was comparable between male partners of women with endometriosis and male partners of the control group based on the International Index of Erectile Function. Logistic regression analyses showed that dyspareunia (OR 0.54; 95% CI 0.39-0.75) and depressive symptoms (OR 0.761; 95% CI 0.58-0.99) were independent and significant negative predictors for sexual functioning. Chronic pelvic pain (OR 0.53; 95% CI 0.35-0.81) and depressive symptoms (OR 0.65; 95% CI 0.44-0.96) were independent and significant negative predictors for quality of life. LIMITATIONS, REASONS FOR CAUTION: Patient recruitment was performed in one tertiary care centre and to a lesser extent one general hospital, possibly leading to an over-representation of patients with more severe endometriosis. All participating women had a partner and are therefore 'survivors' in relationship terms. This may have led to an underestimation of the impact of endometriosis on sexual functioning. WIDER IMPLICATIONS OF THE FINDINGS: It would be worthwhile to further explore the role of depressive symptoms in women with symptomatic endometriosis and to assess the effect of treatment of depressive symptoms on sexual functioning and quality of life. The fact that the partners did not report impaired sexual functioning could be a reassuring thought to women that might be discussed in the consulting room. STUDY FUNDING/COMPETING INTERESTS: The study was funded by the MUMC. An unconditional research grant was given by the Dutch Society of Psychosomatic Obstetrics and Gynaecology (21 June 2011). TRIAL REGISTRATION NUMBER: Not applicable.

RESUMO

OBJECTIVE: To assess the effect on mode of delivery of the routine use of labour epidural analgesia (EA) compared with analgesia on request. DESIGN: Randomised non-inferiority trial. SETTING: One university and one non-university teaching hospital in The Netherlands. POPULATION: Women with a singleton pregnancy in cephalic presentation beyond 36 + 0 weeks' gestation. METHODS: Participants were randomly allocated to receive either routine EA or analgesia on request. Intention-to-treat (ITT) and per-protocol (PP) analyses were performed, with confidence intervals (CI) calculated for the differences in percentages or means. MAIN OUTCOME MEASURES: Rate of operative delivery (instrumental vaginal or caesarean), labour characteristics, and adverse labour and neonatal outcomes. RESULTS: A total of 488 women were randomly allocated to the routine EA (n = 233) or analgesia on request group (n = 255). In the routine EA group, 89.3% (208/233) received EA. According to ITT analysis, 34.8% (81/233) women in the routine EA group had an operative delivery, compared with 26.7% (68/255) in the analgesia on request group (difference 8.1%, 95% CI -0.1 to 16.3). The difference in rate of operative deliveries according to the PP analysis was statistically significant (difference 8.9%, 95% CI 0.4 to 17.4). Inferiority of EA could not be rejected, as in both analyses the upper bound of the confidence interval exceeded the pre-specified inferiority criterion of +10%. Women in the routine EA group had more adverse effects, including hypotension (difference 9.5%, 95% CI 4.2 to 14.9), and motor blockade (difference 6.8%, 95% CI 1.1 to 12.5). CONCLUSION: Non-inferiority of routine EA could not be demonstrated in this trial. Routine EA use is likely to lead to more operative deliveries and more maternal adverse effects. The results of our study do not justify routine use of EA.

RESUMO

OBJECTIVE: To externally validate two models from the USA (entry-to-care [ETC] and close-to-delivery [CTD]) that predict successful intended vaginal birth after caesarean (VBAC) for the Dutch population. DESIGN: A nationwide registration-based cohort study. SETTING: Seventeen hospitals in the Netherlands. POPULATION: Seven hundred and sixty-three pregnant women, each with one previous caesarean section and a viable singleton cephalic pregnancy without a contraindication for an intended VBAC. METHODS: The ETC model comprises the variables maternal age, prepregnancy body mass index (BMI), ethnicity, previous vaginal delivery, previous VBAC and previous nonprogressive labour. The CTD model replaces prepregnancy BMI with third-trimester BMI and adds estimated gestational age at delivery, hypertensive disease of pregnancy, cervical examination and induction of labour. We included consecutive medical records of eligible women who delivered in 2010. For validation, individual probabilities of women who had an intended VBAC were calculated. MAIN OUTCOME MEASURES: Discriminative performance was assessed with the area under the curve (AUC) of the receiver operating characteristic and predictive performance was assessed with calibration plots and the Hosmer-Lemeshow (H-L) statistic. RESULTS: Five hundred and fifteen (67%) of the 763 women had an intended VBAC; 72% of these (371) had an actual VBAC. The AUCs of the ETC and CTD models were 68% (95% CI 63-72%) and 72% (95% CI 67-76%), respectively. The H-L statistic showed a P-value of 0.167 for the ETC model and P = 0.356 for the CTD model, indicating no lack of fit. CONCLUSION: External validation of two predictive models developed in the USA revealed an adequate performance within the Dutch population.

RESUMO

OBJECTIVE: To develop and internally validate a model that predicts the outcome of an intended vaginal birth after caesarean (VBAC) for a Western European population that can be used to personalise counselling for deliveries at term. DESIGN: Registration-based retrospective cohort study. SETTING: Five university teaching hospitals, seven non-university teaching hospitals, and five non-university non-teaching hospitals in the Netherlands. POPULATION: A cohort of 515 women with a history of one caesarean section and a viable singleton pregnancy, without a contraindication for intended VBAC, who delivered at term. METHODS: Potential predictors for a vaginal delivery after caesarean section were chosen based on literature and expert opinions. We internally validated the prediction model using bootstrapping techniques. MAIN OUTCOME MEASURES: Predictors for VBAC. For model validation, the area under the receiver operating characteristic curve (AUC) for discriminative capacity and calibration-per-risk-quantile for accuracy were calculated. RESULTS: A total of 371 out of 515 women had a VBAC (72%). Variables included in the model were: estimated fetal weight greater than the 90(th) percentile in the third trimester; previous non-progressive labour; previous vaginal delivery; induction of labour; pre-pregnancy body mass index; and ethnicity. The AUC was 71% (95% confidence interval, 95% CI = 69-73%), indicating a good discriminative ability. The calibration plot shows that the predicted probabilities are well calibrated, especially from 65% up, which accounts for 77% of the total study population. CONCLUSION: We developed an appropriate Western European population-based prediction model that is aimed to personalise counselling for term deliveries.

RESUMO

INTRODUCTION: Invasive procedures for colorectal cancer can cause iatrogenic tumor cell seeding. Implantation of these exfoliated cells in the surrounding tissue can result in locoregional cancer recurrence. This has been described in endoscopic procedures and major surgical resections, however recurrence in iatrogenic lesions of the anal canal during minimal invasive rectal surgery has not been shown in literature yet. This is the first reported case of recurrent rectal cancer that developed into an anal metastasis at the site where hooks of the Lone Star Retractor disrupted the epithelial lining of the anal canal during a local excision of early rectal cancer using TAMIS. PRESENTATION OF CASE: A 57 year old male was diagnosed with a high risk early stage rectal adenocarcinoma. He was treated with transanal minimally invasive surgery (TAMIS) with the use of a Lone Star retractor and he received subsequent chemo-radiotherapy. 23 months later the patient developed a bleeding mass bulging out of the anus. A true cut and incision biopsy was performed and the pathology report revealed localization of adenocarcinoma at the anal canal which was similar to the earlier diagnosed rectal carcinoma. The patient underwent an abdominal perineal resection and left-sided lymph node dissection. DISCUSSION AND CONCLUSION: This shows that local recurrence through implantation of exfoliated tumor cells can occur in iatrogenic lesions of the anal canal not only in major but also in minimal invasive rectal surgery. Careful tissue handling and rectal washout may reduce the chance of this implantation metastasis.

RESUMO

OBJECTIVE: Review of the literature regarding the relation between the timing of epidural analgesia and the rate of caesarean or instrumental vaginal deliveries. SEARCH STRATEGY: Pubmed, Embase and the Cochrane Library were searched for articles published until 31 July 2010. SELECTION CRITERIA: Studies were selected in which the effects of early latent phase (defined as a cervical dilatation of 3 cm or less) epidural analgesia (including combined-spinal epidural) and late active phase epidural analgesia on the mode of delivery in nulliparous women at 36 weeks of gestation or more were evaluated. DATA COLLECTION AND ANALYSIS: Data extraction was completed by using a data-extraction form. Risk ratio and its 95% confidence intervals were calculated for caesarean delivery and instrumental vaginal delivery. Pooled data were calculated. MAIN RESULTS: The search retrieved 20 relevant articles, of which six fulfilled the selection criteria of inclusion. These six studies reported on 15,399 nulliparous women in spontaneous or induced labour with a request for analgesia. Risk of caesarean delivery (pooled risk ratio 1.02, 95% CI 0.96-1.08) or instrumental vaginal delivery (pooled risk ratio 0.96, 95% CI 0.89-1.05) was not significantly different between groups. AUTHORS' CONCLUSIONS: This systematic review showed no increased risk of caesarean delivery or instrumental vaginal delivery for women receiving early epidural analgesia at cervical dilatation of 3 m or less in comparison with late epidural analgesia.

RESUMO

OBJECTIVE: To compare early-pregnancy changes in cardiac diastolic function between formerly pre-eclamptic women with (RECUR) and without (NORECUR) recurrent pre-eclampsia. DESIGN: Retrospective observational cohort study. SETTING: Tertiary referral centre. POPULATION: Pregnant women with a history of early-onset pre-eclampsia (n = 34). METHODS: The peak mitral filling velocity in early diastole (E) and at atrial contraction (A), and the E/A ratio were assessed before and at 12, 16 and 20 weeks of gestation in the next pregnancy. Differences in early-pregnancy alterations between women with (RECUR) and without (NORECUR) recurrent pre-eclampsia were evaluated by use of mixed design analysis of covariance. MAIN OUTCOME MEASURES: Cardiac function and recurrent pre-eclampsia. RESULTS: In ten women (29%) pre-eclampsia recurred. By 12 weeks of gestation the E/A ratio had increased in the RECUR group, but not in the NORECUR group (P < 0.01). Moreover, from 16 weeks of gestation onwards, the RECUR group had a lower cardiac output and higher systemic vascular resistance as compared with the NORECUR group (P < 0.05). CONCLUSION: Our results suggest that formerly pre-eclamptic women destined to develop recurrent pre-eclampsia differ from their counterparts who do not develop recurrent pre-eclampsia by impaired first-trimester adaptation of cardiac diastolic function.

RESUMO

INTRODUCTION: Iatrogenic recto-urogenital fistulae are refractory complications that rarely heal without surgical intervention. The ongoing local infection causes pain, discomfort and substantially impacts quality of life. Surgical repair requires adequate exposure and space to fill with healthy tissue, which is a major challenge in pelvic redo surgery. An abdominal approach to repair the fistula is associated with major morbidity and often fails to expose the deep pelvis. In our experience a novel transperineal minimally invasive approach a utilizing single incision laparoscopic surgery (SILS) technique could offer improved results. PRESENTATION OF CASES: In the present study, three cases of patients with recto-urogenital fistulae after pelvic surgery are described. Two patients were diagnosed with a rectovesical fistula and one patient with a rectovaginal fistula. In all three cases, a minimally invasive perineal approach, using a SILS port, was used to perform surgical repair. The closure of the fistulae involved: a separate repair of the urethra/bladder or vaginal defect and the rectal defect, followed by interposition of vascularized tissue by either a pudendal thigh fasciocutaneous flap or omentoplasty. DISCUSSION AND CONCLUSION: This study is the first to report on a minimally invasive perineal approach, utilizing a SILS technique for recto-urogenital fistulae repair after previous pelvic surgery. The current approach improves exposure, creates surgical space, optimizes view and allows the interposition of vascularized tissue, without causing substantial blood loss and avoiding major abdominal surgery.

RESUMO

INTRODUCTION: Adalimumab is effective for maintenance of remission in patients with Crohn's disease (CD) at a dose of 40 mg subcutaneously every 2 weeks. However, adalimumab is associated with (long-term) adverse events and is costly. The aim of this study is to demonstrate non-inferiority and cost-effectiveness of disease activity guided adalimumab interval lengthening compared to standard dosing of every other week (EOW). METHODS AND ANALYSIS: The Lengthening Adalimumab Dosing Interval (LADI) study is a pragmatic, multicentre, open label, randomised controlled non-inferiority trial. Non-inferiority is reached if the difference in cumulative incidence of persistent (>8 weeks) flares does not exceed the non-inferiority margin of 15%. 174 CD patients on adalimumab maintenance therapy in long-term (>9 months) clinical and biochemical remission will be included (C-reactive protein (CRP) <10 mg/L, faecal calprotectin (FC) <150 µg/g, Harvey-Bradshaw Index (HBI) <5). Patients will be randomised 2:1 into the intervention (adalimumab interval lengthening) or control group (adalimumab EOW). The intervention group will lengthen the adalimumab administration interval to every 3 weeks, and after 24 weeks to every 4 weeks. Clinical and biochemical disease activity will be monitored every 12 weeks by physician global assessment, HBI, CRP and FC. In case of disease flare, dosing will be increased. A flare is defined as two of three of the following criteria; FC>250 µg/g, CRP≥10 mg/l, HBI≥5. Secondary outcomes include cumulative incidence of transient flares, adverse events, predictors for successful dose reduction and cost-effectiveness. ETHICS AND DISSEMINATION: The study is approved by the Medical Ethics Committee Arnhem-Nijmegen, the Netherlands (registration number NL58948.091.16). Results will be published in peer-reviewed journals and presented at international conferences. TRIAL REGISTRATION NUMBERS: EudraCT registry (2016-003321-42); Clinicaltrials.gov registry (NCT03172377); Dutch trial registry (NTRID6417).

RESUMO

BACKGROUND AND AIMS: There is paucity of data on safety and efficacy of anti-tumour necrosis factor [TNF] in elderly inflammatory bowel disease [IBD] patients. We aimed to compare the long-term treatment failure rates and safety of a first anti-TNF agent in IBD patients between different age groups [<40 years/40-59 years/≥60 years]. METHODS: IBD patients who started a first anti-TNF agent were identified through IBDREAM, a multicentre prospective IBD registry. Competing risk regression was used to study treatment failure, defined as time to drug discontinuation due to adverse events [AEs] or lack of effectiveness, with discontinuation due to remission as a competing risk. RESULTS: A total of 895 IBD patients were included; 546 started anti-TNF at age <40 [61.0%], 268 at age 40-59 [29.9%], and 81 at age ≥60 [9.1%]. Treatment failure rate was higher in the two older groups (subhazard rate [SHR] age ≥60 1.46, SHR age 40-59 1.21; p = 0.03). The SHR in the elderly [>60] was 1.52 for discontinuation due to AEs and 1.11 for lack of effectiveness. Concomitant thiopurine use was associated with a lower treatment failure rate (SHR 0.78, 95% confidence interval [CI] 0.62-0.98, p = 0.031). Serious adverse event [SAE] rate, as well as serious infection rate, were significantly higher in elderly IBD patients [61.2 versus 16.0 and 12.4 per 1000 patient-years, respectively] whereas the malignancy rate was low in all age groups. CONCLUSIONS: Elderly IBD patients starting a first anti-TNF agent showed higher treatment failure rates, but concomitant thiopurine use at baseline was associated with lower failure rates. Elderly IBD patients demonstrated higher rates of SAEs and serious infections.

RESUMO

INTRODUCTION: This study was performed to evaluate mothers' views of their childbirth experience two years after term breech delivery. METHODS: Two years after delivery mothers were asked to fill out a questionnaire concerning their breech birth experience and their view about the care provided to them while giving birth. Outcomes of the planned cesarean section (CS) group were compared with outcomes of the planned vaginal delivery (VD) group, whether or not a vaginal birth was realized or an emergency cesarean section was performed. Any differences were further analyzed by use of logistic regression, controlling for potential confounders. RESULTS: Significantly more women in the planned CS group were reassured about their baby's health (67.4% vs. 37.9%, p=0.0006) at the time of delivery, whereas more women in the planned VD group recalled having been worried about their baby's health at the time of delivery (45.0% vs. 25.6%, p=0.02). Also, more women in the planned VD group experienced more pain during labor and delivery than expected (46.9% vs. 18.5%, p=0.008). In the planned VD group fewer women indicated they had an active say in decision-making (59.1% vs. 85.3%, p=0.001). CONCLUSIONS: Evaluation of the mothers' views of their childbirth experience two years after term breech delivery showed that more women in the planned VD group recalled having been worried about their child's health at the time of delivery, experienced more pain than expected, and reported less involvement in decision-making.

RESUMO

STUDY QUESTION: Do embryo culture media used during an IVF/ICSI treatment have an effect on cognitive development of singleton IVF children at 9 years of age? SUMMARY ANSWER: Cognitive development of children born after culture in two different embryo culture media is comparable. WHAT IS KNOWN ALREADY: Previously, we have shown that the culture medium used in an IVF/ICSI treatment affects birthweight and weight at 2 years of age after alternating assignment to embryo culture in either K-SCICM (Cook) or G1™ Version 3 (Vitrolife). Children with low birthweight are known to have an increased risk for learning disabilities. Data on cognitive development in general of children born after ART are still conflicting, and the only study reporting on the effects of culture medium on cognitive development shows significant differences in cognitive development between two culture medium groups. STUDY DESIGN SIZE DURATION: In this observational cohort follow-up study (MEDIUM-KIDS), parents of all singletons from our abovementioned study were approached after the ninth birthday of their child to participate in an additional follow-up study. Of the 294 eligible children included in the original study, 119 children (70 Vitrolife and 49 Cook) participated in the current study. PARTICIPANTS/MATERIALS SETTING METHODS: All follow-up measurements were performed between March 2014 and December 2016. CITO (Dutch Central Institute for Test Development) developed the Dutch pupil monitoring system, which involves nationwide independent, standardized, academic achievement score tests to monitor the child's school performance twice a year at fixed time points from third grade onward. The tests include language skills (vocabulary and orthography), mathematics and reading capability and comprehension. Results from the tests performed between third and sixth grades, expressed as ability scores, were obtained from the school. To investigate school performance development over the years, we used a mixed effects multilevel model. The least complex model with the best fit was selected to analyze whether culture medium affects cognitive development in our cohort. The study had enough power to detect a difference in ability score that reflects at least one performance category between the two groups. MAIN RESULTS AND THE ROLE OF CHANCE: No differences were seen in baseline characteristics between participants and non-participants (both parental and children characteristics). For all domains, the random intercept model was used. All analyses showed comparable results for the two culture medium groups. No significant differences were observed for any of the cognitive development domains, even after correction for potential confounders. Parental level of education was higher in the IVF group (45%) if compared to the national average level of education (35%), which most likely explains the higher CITO scores for the IVF children if compared to the National ability scores. LIMITATIONS REASONS FOR CAUTION: A limitation of the study was its pseudo-randomized design and the relatively low participation rate of 40.5%. This and the number of missing data prevent us from drawing robust causal conclusions. However, as this is the first and therewith oldest cohort of children where culture medium was allocated alternatingly and used in a blinded setting, in the same period, with all other conditions identical this study gives up until now the best available evidence. WIDER IMPLICATIONS OF THE FINDINGS: Our study analyzes the effects of culture medium on school performance of children born after IVF/ICSI in a prospective cohort study. Although further research on long-term academic skills and also on behavior is essential, our results are reassuring and should make parents of children born after IVF/ICSI feel comfortable with their children's cognitive development. STUDY FUNDING/COMPETING INTERESTS: The study was financially supported by the March of Dimes (Grant no. #6-FY13-153). The sponsor of the study had no role in study design, data collection, data analysis, data interpretation or writing of the report. The authors have no conflicts of interest to declare. TRIAL REGISTRATION NUMBER: NTR4220.

RESUMO

OBJECTIVE: To evaluate maternal health outcomes two years after term breech delivery. DESIGN: This was a non-randomized single-center prospective cohort study. Mothers were asked to fill out questionnaires at two years postpartum to judge their health in the previous three to six months. Outcomes of the planned cesarean section group were compared with outcomes of the planned vaginal delivery group, whether or not a vaginal birth was realized or an emergency cesarean section was performed. RESULTS: One hundred and eighty-three women completed a follow-up questionnaire at two years postpartum. Outcomes of the planned cesarean section group were compared with outcomes of the planned vaginal delivery group, whether or not a vaginal birth was realized or an emergency cesarean section was performed. No differences in maternal experiences concerning breastfeeding, taking care of her child and the relationship with her partner were found between the two groups. Also, no differences were found in all investigated maternal health items, or in sexual activity and fertility. CONCLUSION: Maternal health outcomes two years after term breech delivery were similar after planned cesarean section and planned vaginal delivery.

RESUMO

INTRODUCTION: Research on telephonic consultation in forensic medicine is scarce. This study aimed to create insight in different aspects of telephonic consultation in post-mortem examinations. Besides, the accuracy of advice given by forensic physicians and associations between accuracy and characteristics of forensic physicians were evaluated. METHODS: A descriptive, retrospective study was conducted. Data were obtained from the electronic information system used by the department of forensic medicine in Amsterdam. Cases in which telephonic advice was given, with regard to post-mortem examinations, were identified and the accuracy of advice was appraised. Questionnaires were distributed among forensic physicians in order to obtain information about characteristics of physicians. Hence, associations of these characteristics and accuracy of advice were to be revealed. RESULTS: A total of 938 cases were included. Telephonic advice was most often requested by hospitals (n = 359, 38.3%), followed by general practices (n = 273, 29.1%) and nursing homes (n = 144, 15.4%). Incorrect advice was given significantly more often in cases regarding manner of death compared to other categories of consultation (n = 104 of 110, 94.5%, p < 0.001). Among the forensic physicians, 27.3% (six out of 22) were responsible for 60.9% (67 out of 110 cases) of the cases wherein incorrect advice was given. After correction for dependency of observations, no associations were found between characteristics of physicians or time of consultation and accuracy of advice. CONCLUSION: This study indicates that education concerning post-mortem external examinations is needed for both consulting parties as well as forensic physicians.

RESUMO

OBJECTIVE: The purpose of this prospective cohort study was to determine whether planned vaginal delivery for the term singleton baby in breech position increases the risk of abnormal neurodevelopment at 2 years of age and to assess whether the effect is modified by birth weight. STUDY DESIGN: At 2 years of age, all nonrandomized children born in breech position during our participation in the Term Breech Trial were screened for abnormal neurodevelopment with the Ages and Stages Questionnaire. RESULTS: An Ages and Stages Questionnaire at 2 years of age was obtained in 183 of 203 children (90.1%). Twenty-eight percent of these children showed 1 or more abnormal Ages and Stages Questionnaire domains. There were no differences in the risk of having abnormal Ages and Stages Questionnaire domains between planned vaginal delivery and planned cesarean section (P = .99). There was, however, evidence of interaction between mode of delivery and birth weight, with significantly higher risk in neurodevelopmental delay in children with birth weight greater than 3500 g with planned vaginal birth (adjusted odds ratio for interaction term 3.37; 95% confidence interval 1.14 to 9.95). CONCLUSION: Based on the Ages and Stages Questionnaire results at 2 years of age, planned vaginal delivery is associated with an increased risk of neurodevelopmental delay at 2 years of age in term breech children with a birth weight greater than 3500 g.
