ABSTRACT
OBJECTIVES: To determine if the electrical heart axis in different types of congenital heart defects (CHD) differs from that of a healthy cohort at mid-gestation. METHODS: Non-invasive fetal electrocardiography (NI-fECG) was performed in singleton pregnancies with suspected CHD between 16 and 30 weeks of gestation. The mean electrical heart axis (MEHA) was determined from the fetal vectorcardiogram after correction for fetal orientation. Descriptive statistics were used to determine the MEHA with corresponding 95% confidence intervals (CI) in the frontal plane of all fetuses with CHD and the following subgroups: conotruncal anomalies (CTA), atrioventricular septal defects (AVSD) and hypoplastic right heart syndrome (HRHS). The MEHA of the CHD fetuses as well as the subgroups was compared to the healthy control group using a spherically projected multivariate linear regression analysis. Discriminant analysis was applied to calculate the sensitivity and specificity of the electrical heart axis for CHD detection. RESULTS: The MEHA was determined in 127 fetuses. The MEHA was 83.0° (95% CI: 6.7°; 159.3°) in the total CHD group, and not significantly different from the control group (122.7° (95% CI: 101.7°; 143.6°). The MEHA was 105.6° (95% CI: 46.8°; 164.4°) in the CTA group (n = 54), -27.4° (95% CI: -118.6°; 63.9°) in the AVSD group (n = 9) and 26.0° (95% CI: -34.1°; 86.1°) in the HRHS group (n = 5). The MEHA of the AVSD and the HRHS subgroups were significantly different from the control group (resp. p = 0.04 and p = 0.02). The sensitivity and specificity of the MEHA for the diagnosis of CHD was 50.6% (95% CI 47.5% - 53.7%) and 60.1% (95% CI 57.1% - 63.1%) respectively. CONCLUSION: The MEHA alone does not discriminate between healthy fetuses and fetuses with CHD. However, the left-oriented electrical heart axis in fetuses with AVSD and HRHS was significantly different from the control group suggesting altered cardiac conduction along with the structural defect. TRIAL REGISTRATION: Clinical trial registration number: NL48535.015.14.

OBJECTIVES: Two-dimensional speckle-tracking echocardiography (2D-STE) is a promising technique which allows assessment of fetal cardiac function, and can be used in the evaluation of cardiac and non-cardiac diseases in pregnancy. However, reliable fetal reference values for deformation parameters measured using 2D-STE are needed before it can be introduced into clinical practice. This study aimed to obtain reference values for fetal global longitudinal strain (GLS) and GLS rate (GLSR) measured using 2D-STE and compare right and left ventricular values. METHODS: This was a prospective longitudinal cohort study of uncomplicated pregnancies that underwent echocardiography every 4 weeks from inclusion at 18-21 weeks until delivery to obtain four-chamber loops of the fetal heart. Left and right ventricular GLS and GLSR were measured using 2D-STE at each examination. Using Bayesian mixed-effects models, reference values with lower and upper 5% prediction limits were calculated according to gestational age. Right and left ventricular GLS values according to gestational age were compared using the Wilcoxon signed-rank test. RESULTS: A total of 592 left ventricular and 566 right ventricular GLS and GLSR measurements were obtained from 124 women with uncomplicated pregnancy and non-anomalous, appropriately grown fetuses. Reference values were obtained for both fetal ventricles according to gestational week. GLS and GLSR values of both ventricles increased (i.e. became less negative) significantly during pregnancy. Right ventricular GLS values were significantly higher (i.e. less negative) than the respective left ventricular values at every gestational week. CONCLUSIONS: Reference values were obtained for fetal GLS and GLSR measured using 2D-STE. GLS and GLSR values increased significantly for both ventricles from the second trimester until delivery. GLS values were significantly higher for the right ventricle compared with the left ventricle. Future studies are needed to assess whether the obtained reference values are helpful in clinical practice in the assessment of pregnancy complications, such as fetal growth restriction or cardiac anomaly. © 2022 The Authors.

OBJECTIVE: To investigate the effect of maternal hyperoxygenation on fetal heart rate (FHR) when applied for suspected fetal distress during the second stage of term labor. APPROACH: A single-center randomized controlled trial was conducted in a tertiary care hospital in The Netherlands. Participants were included during the second stage of labor in case of an intermediary or abnormal FHR pattern. Patients were randomized to receive either 100% oxygen at 10 l/min until delivery, or conventional care without additional oxygen. The primary outcome was the change in FHR pattern before and after the onset of the study, measured as the change in depth and duration of FHR decelerations. Secondary outcome measures were features based on phase-rectified signal averaging (PRSA), baseline assignability, and deceleration characteristics of the FHR pattern. MAIN RESULTS: Between March 2016 and April 2018, 117 women were included. The FHR pattern could be analyzed for 71 participants, the other 46 women delivered before the end of the post time-frame. A 2.3% reduction in depth and duration of FHR decelerations was found after maternal hyperoxygenation, compared to a 10% increase in the control group (p = 0.24). Maternal hyperoxygenation had a significantly positive effect on PRSA metrics, with a decrease in PRSA-acceleration capacity (p = 0.03) and PRSA-deceleration capacity (p = 0.02) in the intervention group compared to the control group. SIGNIFICANCE: The difference in depth and duration of decelerations after the start of the study was not significantly different between both study groups. A statistically significant positive effect on PRSA-deceleration capacity and PRSA-acceleration capacity was found after maternal hyperoxygenation, which might be associated with a positive effect on neonatal outcome.

OBJECTIVE: In women with postmenopausal bleeding, endometrial polyps are a frequent finding and the risk of a focal (pre)malignancy in a polyp is up to 6%. Because of this reported risk, the detection of polyps in these women, preferably by a minimally invasive method, is important. The aim of this systematic review was to assess the accuracy of saline contrast sonohysterography (SCSH) for diagnosis of endometrial polyps in women with postmenopausal bleeding. METHODS: In August 2018, an electronic search was performed of MEDLINE, EMBASE and Web of Science databases to identify all diagnostic studies in which SCSH was used to detect endometrial polyps in postmenopausal women. Studies were included if SCSH was performed to detect endometrial polyps in women with postmenopausal bleeding and if detection of a polyp on hysteroscopy or diagnosis on histopathology was used as a reference standard. Two reviewers assessed methodological quality using the quality assessment of diagnostic accuracy studies (QUADAS-2) tool. Two separate analyses were performed for each reference standard. Pooled sensitivity and specificity were calculated using the hierarchical summary receiver-operating characteristics (HSROC) model and HSROC curves were plotted. RESULTS: After selection and quality assessment, five studies were included. Using 'polyps diagnosed with histopathology' as the reference standard, the pooled sensitivity of SCSH was 86.5% (95% CI, 63.6-100%) and the pooled specificity was 91.1% (95% CI, 63.2-100%). Using 'polyps seen on hysteroscopy' as the reference standard, the pooled sensitivity of SCSH was 85.1% (95% CI, 66.9-100%) and the pooled specificity was 84.5% (95% CI, 68.1-100%). Excluding the one study that included women in whom the SCSH examination was reported to be suboptimal, the pooled sensitivity increased to 90.7% (95% CI, 72.8-100%) using hysteroscopy as the reference standard. The sensitivity of hysteroscopy to detect polyps, as reported in two studies, was 81-98%. CONCLUSIONS: Provided that the SCSH examination is of optimal quality, it can be considered as a method to stratify women with postmenopausal bleeding for further diagnostic workup and treatment with hysteroscopy. In women without suspicion of a polypoid lesion on SCSH, and with a benign endometrial sample, expectant management should be considered. Copyright © 2019 ISUOG. Published by John Wiley & Sons Ltd.
Precisión del diagnóstico de la sonohisterografía con contraste salino en la detección de pólipos endometriales en mujeres con hemorragia postmenopáusica: revisión sistemática y metaanálisis OBJETIVO: En las mujeres con hemorragia postmenopáusica, los pólipos endometriales son frecuentes y el riesgo de una (pre)malignidad focal en un pólipo es de hasta el 6%. Debido a este riesgo reportado, es importante la detección de pólipos en estas mujeres, preferiblemente por un método mínimamente invasivo. El objetivo de esta revisión sistemática fue evaluar la precisión de la sonohisterografía con contraste salino (SCSH, por sus siglas en inglés) para el diagnóstico de pólipos endometriales en mujeres con hemorragia postmenopáusica. MÉTODOS: En agosto de 2018 se realizó una búsqueda electrónica en las bases de datos MEDLINE, EMBASE y Web of Science para identificar todos los estudios diagnósticos en los que se utilizó la SCSH para detectar pólipos endometriales en mujeres postmenopáusicas. Los estudios se incluyeron cuando la SCSH se realizó para detectar pólipos endometriales en mujeres con hemorragia postmenopáusica o cuando la detección de un pólipo en la histeroscopia o el diagnóstico sobre la histopatología se utilizó como estándar de referencia. Dos revisores evaluaron la calidad metodológica mediante la evaluación de calidad de la herramienta de estudios de precisión diagnóstica (QUADAS-2). Se realizaron dos análisis separados para cada estándar de referencia. La sensibilidad y especificidad combinadas se calcularon utilizando el modelo jerárquico de resumen de las características operativas del receptor (HSROC, por sus siglas en inglés) y se trazaron las curvas HSROC. RESULTADOS: Después de la selección y la evaluación de calidad, se incluyeron cinco estudios. Utilizando los 'pólipos diagnosticados con histopatología' como estándar de referencia, la sensibilidad combinada de la SCSH fue del 86,5% (IC 95%, 63,6-100%) y la especificidad combinada fue del 91,1% (IC 95%, 63,2-100%). Utilizando como estándar de referencia los 'pólipos observados en la histeroscopia', la sensibilidad combinada de la SCSH fue del 85,1% (IC 95%: 66,9-100%) y la especificidad combinada fue del 84,5% (IC 95%: 68,1-100%). Excluyendo el único estudio que incluyó mujeres en las que se reportó que el examen por SCSH no fue adecuado, la sensibilidad combinada aumentó al 90,7% (IC 95%: 72,8-100%), usando la histeroscopia como estándar de referencia. La sensibilidad de la histeroscopia para detectar pólipos, tal y como se informó en dos estudios, fue del 81-98%. CONCLUSIONES: Siempre que el examen por SCSH sea de calidad óptima, puede considerarse como un método para estratificar a las mujeres con hemorragia postmenopáusica para su posterior diagnóstico y tratamiento con histeroscopia. En mujeres sin sospecha de una lesión polipoide mediante SCSH y con una muestra endometrial benigna, se debe considerar el tratamiento expectante. Copyright © 2019 ISUOG.

Objective: This study aimed to establish the determinants of perceived sleep quality over a longer period of time, taking into account the separate contributions of actigraphy-based sleep measures and self-reported sleep indices. Methods: Fifty participants (52 ± 6.6 years; 27 females) completed two consecutive weeks of home monitoring, during which they kept a sleep-wake diary while their sleep was monitored using a wrist-worn actigraph. The diary included questions on perceived sleep quality, sleep-wake information, and additional factors such as well-being and stress. The data were analyzed using multilevel models to compare a model that included only actigraphy-based sleep measures (model Acti) to a model that included only self-reported sleep measures to explain perceived sleep quality (model Self). In addition, a model based on the self-reported sleep measures and extended with nonsleep-related factors was analyzed to find the most significant determinants of perceived sleep quality (model Extended). Results: Self-reported sleep measures (model Self) explained 61% of the total variance, while actigraphy-based sleep measures (model Acti) only accounted for 41% of the perceived sleep quality. The main predictors in the self-reported model were number of awakenings during the night, sleep onset latency, and wake time after sleep onset. In the extended model, the number of awakenings during the night and total sleep time of the previous night were the strongest determinants of perceived sleep quality, with 64% of the variance explained. Conclusion: In our cohort, perceived sleep quality was mainly determined by self-reported sleep measures and less by actigraphy-based sleep indices. These data further stress the importance of taking multiple nights into account when trying to understand perceived sleep quality.

OBJECTIVE: This study aimed to assess the heterogeneity and stability of cognition in patients with a non-affective psychotic disorder and their unaffected siblings. In addition, we aimed to predict the cognitive subtypes of siblings by their probands. METHOD: Assessments were conducted at baseline, 3 and 6 years in 1119 patients, 1059 siblings and 586 controls from the Genetic Risk and Outcome of Psychosis (GROUP) study. Group-based trajectory modeling was applied to identify trajectories and clustered multinomial logistic regression analysis was used for prediction modeling. A composite score of eight neurocognitive tests was used to measure cognitive performance. RESULTS: Five stable cognitive trajectories ranging from severely altered to high cognitive performance were identified in patients. Likewise, four stable trajectories ranging from moderately altered to high performance were found in siblings. Siblings had a higher risk of cognitive alteration when patients' alteration was mild (OR = 2.21), moderate (OR = 5.70), and severe (OR = 10.07) compared with patients with intact cognitive function. The familial correlation coefficient between pairs of index patients and their siblings was 0.27 (P = 0.003). CONCLUSIONS: The cognitive profiles identified in the current study might be suitable as endophenotypes and could be used in future genetic studies and predicting functional and clinical outcomes.

OBJECTIVES: To evaluate in patients with untreated adult periodontitis, the effect of treatment with a novel pocket irrigator/evacuator device (IED) compared to conventional subgingival debridement (CPT), both provided during the initial phase of active periodontal therapy. METHODS: This study was an examiner-blind, randomized controlled clinical trial using a split-mouth design. Systemically healthy patients with adult periodontitis were selected. Full-mouth probing pocket depth (PPD), gingival bleeding on pocket probing scores (BOPP), gingival recession (REC) and dental plaque (PI) were assessed at baseline. All participants received oral hygiene instructions and supragingival prophylaxis including polishing. In 2 randomly assigned contra-lateral quadrants, approximal sites were irrigated with the IED, whereas in the other quadrants, CPT was provided. The CPT consisted of subgingival debridement using ultrasonic devices followed by the use of hand instruments. At 3 months post-treatment, the clinical parameters were re-assessed. RESULTS: Twenty-five patients met the inclusion criteria and were willing to participate. At 3 months post-treatment, the PPD and BOPP had significantly improved for both treatment modalities. Pockets of ≥5 mm reduced by 0.64 mm in the IED group (P < .001), compared to a reduction of 0.82 mm for the CPT group (P < .001). With respect to the primary outcome parameter (PPD) and BI, the results with the IED were less pronounced. Between the test and control groups, no significant differences were observed for REC and PI. CONCLUSIONS: Oral hygiene instructions, supragingival prophylaxis and subgingival lavage with the IED resulted in a significant reduction in PPD and BOPP. However, the effect does not reach the results of CPT which included the subgingival use of ultrasonic and hand instruments.

BACKGROUND: Multimorbidity may impose an overwhelming burden on patients with psychosis and is affected by gender and age. Our aim is to study the independent role of familial liability to psychosis as a risk factor for multimorbidity. METHODS: We performed the study within the framework of the Genetic Risk and Outcome of Psychosis (GROUP) project. Overall, we compared 1024 psychotic patients, 994 unaffected siblings and 566 controls on the prevalence of 125 lifetime diseases, and 19 self-reported somatic complaints. Multimorbidity was defined as the presence of two or more complaints/diseases in the same individual. Generalized linear mixed model (GLMM) were used to investigate the effects of gender, age (adolescent, young, older) and familial liability (patients, siblings, controls) and their interactions on multimorbidity. RESULTS: Familial liability had a significant effect on multimorbidity of either complaints or diseases. Patients had a higher prevalence of multimorbidity of complaints compared to siblings (OR 2.20, 95% CI 1.79-2.69, P<0.001) and to controls (3.05, 2.35-3.96, P<0.001). In physical health multimorbidity, patients (OR 1.36, 95% CI 1.05-1.75, P=0.018), but not siblings, had significantly higher prevalence than controls. Similar finding were observed for multimorbidity of lifetime diseases, including psychiatric diseases. Significant results were observed for complaints and disease multimorbidity across gender and age groups. CONCLUSION: Multimorbidity is a common burden, significantly more prevalent in patients and their unaffected siblings. Familial liability to psychosis showed an independent effect on multimorbidity; gender and age are also important factors determining multimorbidity.

BACKGROUND: The CEAwatch randomized trial showed that follow-up with intensive carcinoembryonic antigen (CEA) monitoring (CEAwatch protocol) was better than care as usual (CAU) for early postoperative detection of colorectal cancer recurrence. The aim of this study was to calculate overall survival (OS) and disease-specific survival (DSS). METHODS: For all patients with recurrence, OS and DSS were compared between patients detected by the CEAwatch protocol versus CAU, and by the method of detection of recurrence, using Cox regression models. RESULTS: Some 238 patients with recurrence were analysed (7·5 per cent); a total of 108 recurrences were detected by CEA blood test, 64 (55·2 per cent) within the CEAwatch protocol and 44 (41·9 per cent) in the CAU group (P = 0·007). Only 16 recurrences (13·8 per cent) were detected by patient self-report in the CEAwatch group, compared with 33 (31·4 per cent) in the CAU group. There was no significant improvement in either OS or DSS with the CEAwatch protocol compared with CAU: hazard ratio 0·73 (95 per cent 0·46 to 1·17) and 0·78 (0·48 to 1·28) respectively. There were no differences in survival when recurrence was detected by CT versus CEA measurement, but both of these methods yielded better survival outcomes than detection by patient self-report. CONCLUSION: There was no direct survival benefit in favour of the intensive programme, but the CEAwatch protocol led to a higher proportion of recurrences being detected by CEA-based blood test and reduced the number detected by patient self-report. This is important because detection of recurrence by blood test was associated with significantly better survival than patient self-report, indirectly supporting use of the CEAwatch protocol.

Voriconazole (VCZ) exhibits great inter- and intrapatient variability. The latter variation cannot exclusively be explained by concomitant medications, liver disease or dysfunction, and genetic polymorphisms in cytochrome P450 2C19 (CYP2C19). We hypothesized that inflammatory response in patients under VCZ medication might also influence this fluctuation in concentrations. In this study, we explored the association between inflammation, reflected by the C-reactive protein (CRP) concentration, and VCZ trough concentrations over time. A retrospective analysis of data was performed for patients with more than one steady-state VCZ trough concentration and a CRP concentration measured on the same day. A longitudinal analysis was used for series of observations obtained from many study participants over time. The approach involved inclusion of random effects and autocorrelation in linear models to reflect within-person cross-time correlation. A total of 50 patients were eligible for the study, resulting in 139 observations (paired VCZ and CRP concentrations) for the analysis, ranging from 2 to 6 observations per study participant. Inflammation, marked by the CRP concentration, had a significant association with VCZ trough concentrations (P < 0.001). Covariates such as age and interacting comedication ([es]omeprazole), also showed a significant correlation between VCZ and CRP concentrations (P < 0.05). The intrapatient variation of trough concentrations of VCZ was 1.401 (confidence interval [CI], 0.881 to 2.567), and the interpatient variation was 1.756 (CI, 0.934 to 4.440). The autocorrelation between VCZ trough concentrations at two sequential time points was calculated at 0.71 (CI, 0.51 to 0.92). The inflammatory response appears to play a significant role in the largely unpredictable pharmacokinetics of VCZ, especially in patients with high inflammatory response, as reflected by high CRP concentrations.

OBJECTIVE: Distribution of age of onset of recurrent respiratory papillomatosis (RRP) is generally described to be bimodal, with peaks at approximately 5 years and 30 years. This assumption has never been scientifically confirmed, and authors tend to refer to an article that does not describe distribution. Knowledge of the distribution of age of onset is important for virological and epidemiological comprehension. The objective of this study was to determine the distribution of age of onset of RRP in a large international sample. DESIGN: Cross-sectional distribution analysis. PARTICIPANTS: Laryngologists from 12 European hospitals provided information on date of birth and date of onset of all their RRP patients treated between 1998 and 2012. Centers that exclusively treated either patients with juvenile onset RRP or patients with adult onset RRP, or were less accessible for one of these groups, were excluded to prevent skewness. MAIN OUTCOME MEASURES: A mixture model was implemented to describe distribution of age of onset. The best fitting model was selected using the Bayesian information criterion. RESULTS: Six hundred and thirty-nine patients were included in the analysis. Age of onset was described by a three component mixture distribution with lognormally distributed components. Recurrent respiratory papillomatosis starts at three median ages 7, 35 and 64 years. CONCLUSIONS: Distribution of age of onset of RRP shows three peaks. In addition to the already adopted idea of age peaks at paediatric and adult age, there is an additional peak around the age of 64.

Voriconazole pharmacokinetics shows a large inter- and intrapatient variability. Inflammation is associated with changes in the expression of CYP isoenzymes. Here, we evaluated the influence of inflammation, marked by C-reactive protein (CRP) levels in blood, on the metabolism of voriconazole. Observational data showed an association between CRP level and the ratio of voriconazole N-oxide to voriconazole.

BACKGROUND: Treatment of hidradenitis suppurativa (HS) is a difficult undertaking, especially as there is no consensus on what surgical technique is preferred. At our centre severe HS (Hurley II/III) is operated under general anaesthesia, mostly with the STEEP procedure. OBJECTIVES: To investigate characteristics, surgical outcomes and patient satisfaction of HS patients who underwent deroofing or STEEP under general anaesthesia. METHODS: A clinical records-based retrospective analysis was conducted of all patients who had surgery under general anaesthesia between 1999 and 2013. Patient satisfaction was retrospectively investigated with questionnaires. RESULTS: A total of 482 operations (363 primary operations and 119 re-operations) were performed during the study period. The proportion of women in the included population was 68%. The median diagnostic delay (patient's and doctor's delay) was 6.5 years. Relapses occurred after 29.2% of primary operations. Women had higher relapse rates than men [odds ratio 2.85 (1.07;7.61)]. Hypergranulation of the wound was the most common complication and occurred in 7% of all operations. The median score patients attributed to the medical effect of surgery was eight of 10 (zero corresponding to very dissatisfied and 10 to very satisfied). CONCLUSION: The diagnostic delay in HS is long due to a lack of knowledge in both patients and health care professionals, indicating that there is a need for education. Deroofing and the STEEP are effective surgical procedures in severe cases of HS and lead to a relatively high patient satisfaction. The postoperative relapse risk is higher in women. Prospective studies are required for the development of clear guidelines on the appropriate choice of surgery.

BACKGROUND: The purpose of the study was to determine the impact of young age on health-related quality of life (HRQoL) by comparing HRQoL of younger and older breast cancer patients, corrected for confounding, and of young patients and a general Dutch population. METHODS: The population consisted of breast cancer survivors (stage 0-III) after breast-conserving surgery and radiotherapy. Health-related quality of life was prospectively assessed using the EORTC QLQ-C30 and QLQ-BR23 questionnaires. The association between age (⩽50; 51-70; ⩾70 years) and HRQoL over time was analysed with mixed modelling. The clinical relevance of differences between/within age groups was estimated with Cohen's D and consensus-based guidelines. The HRQoL data from the young patient cohort were compared with Dutch reference data at 3 years after radiotherapy. RESULTS: A total of 1420 patients completed 3200 questionnaires. Median follow-up was 34 (range 6-70) months. Median age was 59 (range 28-85) years. Compared with older subjects, young women reported worse HRQoL in the first year after radiotherapy, but clinical relevance was limited. Three years after radiotherapy, HRQoL values in the younger group were equal to those in the reference population. Pain and fatigue after radiotherapy improved, with medium clinical relevance. CONCLUSIONS: Three years after radiotherapy for breast cancer, young age was not a risk factor for decreased HRQoL.

AIM: Obesity tracks from childhood into adulthood. We evaluated the effect of early stimulation of physical activity on growth, body composition, motor activity and motor development in toddlers. METHODS: We performed a cluster randomised controlled single-blinded trial in Dutch Well Baby Clinics, with seven nurses and 96 children (40% girls) randomised to the intervention group and six nurses and 65 children (57% girls) to the control group. Intervention nurses advised parents on stimulating motor development and physical activity during regular visits at 2 weeks and two, four, eight and 11 months. Baseline characteristics such as birthweight and mode of feeding were comparable. Outcomes at two-and-a-half years included anthropometry, skinfold thicknesses, bioelectrical impedance analyses, motor development and daily physical activity. We used linear mixed models with nurses as cluster. RESULTS: We evaluated 143 children (89 intervention, 54 control) as 18 dropped out. Skinfolds were significantly lower in intervention children (29.6 ± 4.7 mm) than controls (32.4 ± 6.0 mm), without differences in motor development or daily physical activity. Female interventions showed lower weight, skinfolds, waist and hip circumference. CONCLUSION: An activity stimulating programme during the child's first year improved indicators of adiposity when they were toddlers, especially in girls. Further research should determine whether these effects persist.

OBJECTIVES: Minimalist running shoes have been proposed as an alternative to barefoot running. However, several studies have reported cases of forefoot stress fractures after switching from standard to minimalist shoes. Therefore, the aim of the current study was to investigate the differences in plantar pressure in the forefoot region between running with a minimalist shoe and running with a standard shoe in healthy female runners during overground running. DESIGN: Randomized crossover design. METHODS: In-shoe plantar pressure measurements were recorded from eighteen healthy female runners. Peak pressure, maximum mean pressure, pressure time integral and instant of peak pressure were assessed for seven foot areas. Force time integral, stride time, stance time, swing time, shoe comfort and landing type were assessed for both shoe types. A linear mixed model was used to analyze the data. RESULTS: Peak pressure and maximum mean pressure were higher in the medial forefoot (respectively 13.5% and 7.46%), central forefoot (respectively 37.5% and 29.2%) and lateral forefoot (respectively 37.9% and 20.4%) for the minimalist shoe condition. Stance time was reduced with 3.81%. No relevant differences in shoe comfort or landing strategy were found. CONCLUSIONS: Running with a minimalist shoe increased plantar pressure without a change in landing pattern. This increased pressure in the forefoot region might play a role in the occurrence of metatarsal stress fractures in runners who switched to minimalist shoes and warrants a cautious approach to transitioning to minimalist shoe use.

BACKGROUND: Few studies have investigated the efficacy of repetitive transcranial magnetic stimulation (rTMS) treatment for negative symptoms of schizophrenia, reporting inconsistent results. We aimed to investigate whether 10 Hz stimulation of the bilateral dorsolateral prefrontal cortex during 3 weeks enhances treatment effects. METHOD: A multicenter double-blind randomized controlled trial was performed in 32 patients with schizophrenia or schizo-affective disorder, and moderate to severe negative symptoms [Positive and Negative Syndrome Scale (PANSS) negative subscale ⩾15]. Patients were randomized to a 3-week course of active or sham rTMS. Primary outcome was severity of negative symptoms as measured with the Scale for the Assessment of Negative Symptoms (SANS) and the PANSS negative symptom score. Secondary outcome measures included cognition, insight, quality of life and mood. Subjects were followed up at 4 weeks and at 3 months. For analysis of the data a mixed-effects linear model was used. RESULTS: A significant improvement of the SANS in the active group compared with sham up to 3 months follow-up (p = 0.03) was found. The PANSS negative symptom scores did not show a significant change (p = 0.19). Of the cognitive tests, only one showed a significant improvement after rTMS as compared with sham. Finally, a significant change of insight was found with better scores in the treatment group. CONCLUSIONS: Bilateral 10 Hz prefrontal rTMS reduced negative symptoms, as measured with the SANS. More studies are needed to investigate optimal parameters for rTMS, the cognitive effects and the neural basis.
