Abstract

Studying monoaminergic seasonality is likely to improve our understanding of neurobiological mechanisms underlying season-associated physiological and pathophysiological behavior. Studies of monoaminergic seasonality and the influence of the serotonin-transporter-linked polymorphic region (5-HTTLPR) on serotonin seasonality have yielded conflicting results, possibly due to lack of power and absence of multi-year analyses. We aimed to assess the extent of seasonal monoamine turnover and examined the possible involvement of the 5-HTTLPR. To determine the influence of seasonality on monoamine turnover, 5-hydroxyindoleacetic acid (5-HIAA) and homovanillic acid (HVA) were measured in the cerebrospinal fluid of 479 human subjects collected during a 3-year period. Cosine and non-parametric seasonal modeling were applied to both metabolites. We computed serotonin (5-HT) seasonality values and performed an association analysis with the s/l alleles of the 5-HTTLPR. Depressive symptomatology was assessed using the Beck Depression Inventory-II. Circannual variation in 5-HIAA fitted a spring-peak cosine model that was significantly associated with sampling month (P=0.0074). Season of sampling explained 5.4% (P=1.57 × 10(-7)) of the variance in 5-HIAA concentrations. The 5-HTTLPR s-allele was associated with increased 5-HIAA seasonality (standardized regression coefficient=0.12, P=0.020, N=393). 5-HIAA seasonality correlated with depressive symptoms (Spearman's rho=0.13, P=0.018, N=345). In conclusion, we highlight a dose-dependent association of the 5-HTTLPR with 5-HIAA seasonality and a positive correlation between 5-HIAA seasonality and depressive symptomatology. The presented data set the stage for follow-up in clinical populations with a role for seasonality, such as affective disorders.

Abstract

PurposeCure rate models accounting for cured and uncured patients, provide additional insights into long and short term survival. We aim to better understand the prognostic value of histologic response and chemotherapy intensification on cure fraction and progression-free survival (PFS) for the uncured patients.MethodsA logistic model is assumed for the effect of histologic response and intensified chemotherapy on the cure status, while a Cox regression model is estimated only for the uncured patients on PFS. The mixture cure model is used to simultaneously study these two effects.ResultsHistologic response is a strong prognostic factor for the cure status (OR: 3.00 [1.75-5.17]), but it has no clear effect on PFS for the uncured patients (HR: 0.78 [0.53-1.16]). The cure fractions are 55% [46%-63%] and 29% [22%-35%] among patients with good histologic response (GR) and poor responders (PR) respectively. The intensified regimen was associated with higher cure fraction among PR (OR: 1.90 [0.93 – 3.89]), with no evidence of effect for GR (OR: 0.78 [0.38 – 1.59]).ConclusionsAccounting for cured patients is valuable in distinguishing the covariate effects on cure and PFS. Estimating cure chances based on these prognostic factors is relevant for counseling patients and can affect treatment decisions.

A right hemicolectomy is among the most commonly performed operations for colon cancer, but modern high-quality, multination data addressing the morbidity and mortality rates are lacking.This study reports the morbidity and mortality rates for right-sided colon cancer and identifies predictors for unfavorable short-term outcome after right hemicolectomy.This was a snapshot observational prospective study.The study was conducted as a multicenter international study.The 2015 European Society of Coloproctology snapshot study was a prospective multicenter international series that included all patients undergoing elective or emergency right hemicolectomy or ileocecal resection over a 2-month period in early 2015. This is a subanalysis of the colon cancer cohort of patients.Predictors for anastomotic leak and 30-day postoperative morbidity and mortality were assessed using multivariable mixed-effect logistic regression models after variables selection with the Lasso method.Of the 2515 included patients, an anastomosis was performed in 97.2% (n = 2444), handsewn in 38.5% (n = 940) and stapled in 61.5% (n = 1504) cases. The overall anastomotic leak rate was 7.4% (180/2444), 30-day morbidity was 38.0% (n = 956), and mortality was 2.6% (n = 66). Patients with anastomotic leak had a significantly increased mortality rate (10.6% vs 1.6% no-leak patients; p0.001). At multivariable analysis the following variables were associated with anastomotic leak: longer duration of surgery (OR = 1.007 per min; p = 0.0037), open approach (OR = 1.9; p = 0.0037), and stapled anastomosis (OR = 1.5; p = 0.041).This is an observational study, and therefore selection bias could be present. For this reason, a multivariable logistic regression model was performed, trying to correct possible confounding factors.Anastomotic leak after oncologic right hemicolectomy is a frequent complication, and it is associated with increased mortality. The key contributing surgical factors for anastomotic leak were anastomotic technique, surgical approach, and duration of surgery. See Video Abstract at http://links.lww.com/DCR/B165. PREDICTORES DE FUGA ANASTOMóTICA, COMPLICACIONES POSTOPERATORIAS Y MORTALIDAD DESPUéS DE LA COLECTOMíA DERECHA POR CáNCER: RESULTADOS DE UNA AUDITORíA INTERNACIONAL DE CORTO PLAZO: La hemicolectomía derecha se encuentra entre las operaciones más frecuentemente realizadas para cáncer de colon, pero faltan datos modernos multinacionales de alta calidad, que aborden las tasas de morbilidad y mortalidad.Reportar la tasa de morbilidad y mortalidad para cáncer de colon del lado derecho, e identificar predictores de resultados desfavorables a corto plazo, después de la hemicolectomía derecha.Estudio prospectivo observacional de corto plazo.Estudio multicéntrico internacional.El estudio de corto plazo de la Sociedad Europea de Coloproctología de 2015, fue una serie prospectiva multicéntrica internacional, que incluyó a todos los pacientes sometidos a hemicolectomía derecha electiva, de emergencia o resección ileocecal, por un período de dos meses y a principios de 2015. Este es un subanálisis, cohorte de pacientes con cáncer de colon.Los predictores de fuga anastomótica, morbilidad y mortalidad postoperatorias a los 30 días, se evaluaron usando modelos de regresión logística de efectos multivariables mixtos, después de la selección de variables con el método Lasso.De los 2,515 pacientes incluidos, se realizó una anastomosis en el 97,2% (n = 2,444); sutura manual en 38.5% (n = 940) y por engrapadora en 61.5% (n = 1504) casos. La tasa global de fuga anastomótica fue del 7,4% (180/2,444), morbilidad a los 30 días fue del 38,0% (n = 956) y la mortalidad fue del 2,6% (n = 66). Los pacientes con fuga anastomótica tuvieron una tasa de mortalidad significativamente mayor (10,6% frente al 1,6% de pacientes sin fuga, p0,001). En el análisis multivariable, las siguientes variables se asociaron con la fuga anastomótica: mayor duración de la cirugía (OR 1.007 por minuto, p = 0.0037), abordaje abierto (OR 1.9, p = 0.0037) y anastomosis por engrapadora (OR 1.5, p = 0.041).Este es un estudio observacional y por lo tanto podría estar presente el sesgo de selección. Por esta razón, se realizó un modelo de regresión logística multivariable, tratando de corregir posibles factores de confusión.La fuga anastomótica después de la hemicolectomía derecha oncológica, es una complicación frecuente y asociada a mayor mortalidad. Los factores quirúrgicos clave que contribuyeron a la fuga anastomótica, fueron la técnica anastomótica, abordaje quirúrgico y duración de la cirugía.

Abstract

Study Question: What is the predictive performance of a currently recommended prediction model in an external Dutch cohort of couples with unexplained recurrent pregnancy loss (RPL)?Summary Answer: The model shows poor predictive performance on a new population; it overestimates, predicts too extremely and has a poor discriminative ability.What Is Known Already: In 50-75% of couples with RPL, no risk factor or cause can be determined and RPL remains unexplained. Clinical management in RPL is primarily focused on providing supportive care, in which counselling on prognosis is a main pillar. A frequently used prediction model for unexplained RPL, developed by Brigham et al. in 1999, estimates the chance of a successful pregnancy based on number of previous pregnancy losses and maternal age. This prediction model has never been externally validated.Study Design, Size, Duration: This retrospective cohort study consisted of 739 couples with unexplained RPL who visited the RPL clinic of the Leiden University Medical Centre between 2004 and 2019.Participants/materials, Setting, Methods: Unexplained RPL was defined as the loss of two or more pregnancies before 24 weeks, without the presence of an identifiable cause for the pregnancy losses, according to the ESHRE guideline. Obstetrical history and maternal age were noted at intake at the RPL clinic. The outcome of the first pregnancy after intake was documented. The performance of Brigham's model was evaluated through calibration and discrimination, in which the predicted pregnancy rates were compared to the observed pregnancy rates.Main Results and the Role Of Chance: The cohort included 739 women with a mean age of 33.1 years (±4.7 years) and with a median of three pregnancy losses at intake (range 2-10). The mean predicted pregnancy success rate was 9.8 percentage points higher in the Brigham model than the observed pregnancy success rate in the dataset (73.9% vs 64.0% (95% CI for the 9.8% difference 6.3-13.3%)). Calibration showed overestimation of the model and too extreme predictions, with a negative calibration intercept of -0.46 (95% CI -0.62 to -0.31) and a calibration slope of 0.42 (95% CI 0.11-0.73). The discriminative ability of the model was very low with a concordance statistic of 0.55 (95% CI 0.51-0.59). Recalibration of the Brigham model hardly improved the c-statistic (0.57; 95% CI 0.53-0.62).Limitations, Reasons For Caution: This is a retrospective study in which only the first pregnancy after intake was registered. There was no time frame as inclusion criterium, which is of importance in the counselling of couples with unexplained RPL. Only cases with a known pregnancy outcome were included.Wider Implications Of the Findings: This is the first study externally validating the Brigham prognostic model that estimates the chance of a successful pregnancy in couples with unexplained RPL. The results show that the frequently used model overestimates the chances of a successful pregnancy, that predictions are too extreme on both the high and low ends and that they are not much more discriminative than random luck. There is a need for revising the prediction model to estimate the chance of a successful pregnancy in couples with unexplained RPL more accurately.Study Funding/competing Interest(s): No external funding was used and no competing interests were declared.Trial Registration Number: N/A.

Abstract

Research question: Hysterosalpingography (HSG) with an oil-based contrast has been shown to increase ongoing pregnancy rates compared with HSG with water-based contrast, but it remains unclear if an effect of HSG occurs compared with no HSG. Design: A secondary data-analysis of a prospective cohort study among 4556 couples that presented with unexplained subfertility in 38 clinics in the Netherlands between January 2002 and December 2004. A time-varying Cox regression with inverse probability of treatment weighing was used to analyse ongoing pregnancy rates in women after undergoing the HSG procedure (with the use of either water- or oil-based contrast media) compared with women who did not undergo HSG. Results: The probability of natural conception within 24 months after first presentation at the fertility clinic was increased after HSG, regardless of the type of contrast medium used, compared with no HSG (adjusted hazard ratio 1.48, 95% CI 1.26 to 1.73, corresponding to an absolute increase in 6-month pregnancy rate of +6%). When this analysis was limited to HSGs that were made with water-contrast, the treatment effect remained (adjusted hazard ratio 1.40, 95% CI 1.16 to 1.70). Conclusions: HSG increases the ongoing pregnancy rate of couples with unexplained subfertility compared with no HSG, regardless of the contrast medium used. Results need to be validated in future, preferably randomized, studies.

Abstract

Objective: To evaluate if immediate catheter removal (ICR) after laparoscopic hysterectomy is associated with similar retention outcomes compared with delayed removal (DCR). Study design: Non-inferiority randomised controlled trial. Population: Women undergoing laparoscopic hysterectomy in six hospitals in the Netherlands. Methods: Women were randomised to ICR or DCR (between 18 and 24 hours after surgery). Primary outcome: The inability to void within 6 hours after catheter removal. Results: One hundred and fifty-five women were randomised to ICR (n = 74) and DCR (n = 81). The intention-to-treat and per-protocol analysis could not demonstrate the non-inferiority of ICR: ten women with ICR could not urinate spontaneously within 6 hours compared with none in the delayed group (risk difference 13.5%, 5.6–24.8, P = 0.88). However, seven of these women could void spontaneously within 9 hours without additional intervention. Regarding the secondary outcomes, eight women from the delayed group requested earlier catheter removal because of complaints (9.9%). Three women with ICR (4.1%) had a urinary tract infection postoperatively versus eight with DCR (9.9%, risk difference −5.8%, −15.1 to 3.5, P = 0.215). Women with ICR mobilised significantly earlier (5.7 hours, 0.8–23.3 versus 21.0 hours, 1.4–29.9; P ≤ 0.001). Conclusion: The non-inferiority of ICR could not be demonstrated in terms of urinary retention 6 hours after procedure. However, 70% of the women with voiding difficulties could void spontaneously within 9 hours after laparoscopic hysterectomy. It is therefore questionable if all observed urinary retention cases were clinically relevant. As a result, the clinical advantages of ICR may still outweigh the risk of bladder retention and it should therefore be considered after uncomplicated laparoscopic hysterectomy. Tweetable abstract: The advantages of immediate catheter removal after laparoscopic hysterectomy seem to outweigh the risk of bladder retention., Medical Instruments & Bio-Inspired Technology

Abstract

Intravenous immunoglobulin (IVIG) is a potential therapy for chronic inflammatory demyelinating polyneuropathy (CIDP). To investigate the efficacy and safety of the IVIG IgPro10 (Privigen) for treatment of CIDP, results from Privigen Impact on Mobility and Autonomy (PRIMA), a prospective, open-label, single-arm study of IVIG in immunoglobulin (Ig)-naïve or IVIG pre-treated subjects (NCT01184846, n = 28) and Polyneuropathy And Treatment with Hizentra (PATH), a double-blind, randomized study including an open-label, single-arm IVIG phase in IVIG pre-treated subjects (NCT01545076, IVIG restabilization phase n = 207) were analyzed separately and together (n = 235). Efficacy assessments included change in adjusted inflammatory neuropathy cause and treatment (INCAT) score, grip strength and Medical Research Council (MRC) sum score. Adverse drug reactions (ADRs) and ADRs/infusion were recorded. Adjusted INCAT response rate was 60.7% in all PRIMA subjects at Week 25 (76.9% in IVIG pre-treated subjects) and 72.9% in PATH. In the pooled cohort (n = 235), INCAT response rate was 71.5%; median time to INCAT improvement was 4.3 weeks. No clear demographic differences were noticed between early (responding before Week 7, n = 148) and late responders (n = 21). In the pooled cohort, median change from baseline to last observation was -1.0 (interquartile range -2.0; 0.0) point for INCAT score; +8.0 (0.0; 20.0) kPa for maximum grip strength; +3.0 (1.0; 7.0) points for MRC sum score. In the pooled cohort, 271 ADRs were reported in 105 subjects (44.7%), a rate of 0.144 ADRs per infusion. This analysis confirms the efficacy and safety of IgPro10, a recently FDA-approved IVIG for CIDP, in a population of mainly pre-treated subjects with CIDP [Correction added on 14 March 2019 after first online publication: the INCAT response rate has been corrected.].

Abstract

In patients with chronic inflammatory demyelinating polyneuropathy (CIDP), intravenous immunoglobulin (IVIG) is recommended to be periodically reduced to assess the need for ongoing therapy. However, little is known about the effectiveness of restabilization with IVIG in patients who worsen after IVIG withdrawal. In the Polyneuropathy And Treatment with Hizentra (PATH) study, the pre-randomization period included sudden stopping of IVIG followed by 12 weeks of observation. Those deteriorating were then restabilized with IVIG. Of 245 subjects who stopped IVIG, 28 did not show signs of clinical deterioration within 12 weeks. Two hundred and seven received IVIG restabilization with an induction dose of 2 g/kg bodyweight (bw) IgPro10 (Privigen, CSL Behring, King of Prussia, Pennsylvania) and maintenance doses of 1 g/kg bw every 3 weeks for up to 13 weeks. Signs of clinical improvement were seen in almost all (n = 188; 91%) subjects. During IVIG restabilization, 35 subjects either did not show CIDP stability (n = 21, analyzed as n = 22 as an additional subject was randomized in error) or withdrew for other reasons (n = 14). Of the 22 subjects who did not achieve clinical stability, follow-up information in 16 subjects after an additional 4 weeks was obtained. Nine subjects were reported to have improved, leaving a maximum of 27 subjects (13%) who either showed no signs of clinical improvement during the restabilization phase and 4 weeks post-study or withdrew for other reasons. In conclusion, sudden IVIG withdrawal was effective in detecting ongoing immunoglobulin G dependency with a small risk for subjects not returning to their baseline 17 weeks after withdrawal.

Abstract

Background: Pelvic endometriosis is often mentioned as one of the variables influencing surgical outcomes of laparoscopic hysterectomy (LH). However, its additional surgical risks have not been well established. The aim of this study was to analyze to what extent concomitant endometriosis influences surgical outcomes of LH and to determine if it should be considered as case-mix variable. Results: A total of 2655 LH’s were analyzed, of which 397 (15.0%) with concomitant endometriosis. For blood loss and operative time, no measurable association was found for stages I (n = 106) and II (n = 103) endometriosis compared to LH without endometriosis. LH with stages III (n = 93) and IV (n = 95) endometriosis were associated with more intra-operative blood loss (p = <.001) and a prolonged operative time (p = <.001) compared to LH without endometriosis. No significant association was found between endometriosis (all stages) and complications (p =.62). Conclusions: The findings of our study have provided numeric support for the influence of concomitant endometriosis on surgical outcomes of LH, without bowel or bladder dissection. Only stages III and IV were associated with a longer operative time and more blood loss and should thus be considered as case-mix variables in future quality measurement tools., Medical Instruments & Bio-Inspired Technology

Abstract

Patients with chronic inflammatory demyelinating polyneuropathy (CIDP) often require long-term intravenous immunoglobulin (IVIG) maintenance therapy. Subcutaneous immunoglobulin (SCIG) offers an alternative administration option with anticipated improvements in patient quality of life, convenience, and flexibility. To evaluate IgPro20 (SCIG) as a maintenance treatment in CIDP. A randomized, double-blind trial in CIDP patients (n=172) investigated 0.2 and 0.4 g/kg weekly doses of IgPro20 versus placebo. The primary outcome was percentage of patients with CIDP relapse/withdrawal during 24-weeks of treatment determined by Inflammatory Neuropathy Cause and Treatment score. Secondary endpoints included grip strength and patient satisfaction. Both IgPro20 doses significantly reduced rate of CIDP relapse/withdrawal versus placebo. Grip strength remained stable with Hizentra®, but deteriorated with placebo. Most subjects preferred SCIG over IVIG. Local reactions, reported in 33% of IgPro20-treated patients, were mild or moderate in intensity. IgPro20 is efficacious and well-tolerated as maintenance treatment in CIDP.
