Langendijk P, Fleuren M, Venrooy K, Ernst K, Page G. Effect of low colostrum intake on gastrointestinal development and uterine and cervical morphometrical architecture in the neonatal gilt. Animal 2023; 17:100725. [PMID: 36812720 DOI: 10.1016/j.animal.2023.100725] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2022] [Revised: 01/24/2023] [Accepted: 01/26/2023] [Indexed: 02/05/2023] Open
Abstract
To assess the importance of natural variation in colostrum intake on piglet gastrointestinal and reproductive development, two equally sized female piglets from each of 27 litters were selected, one with low (average 226 g) and one with high (average 401 g) colostrum intake. At weaning (23 d of age), piglets were euthanised to perform macromorphological measurements on ileum, colon, cervix and uterus tissues, and to obtain tissue samples from the cervix and uterus for histology. Sections of uterine and cervical preparations were analysed using digital image analysis. Despite being selected for the same birth weight (average 1.1 kg, standard deviation 0.18 kg), piglets with low colostrum intake weighed 5.91 ± 0.17 kg and piglets with high colostrum intake weighed 6.96 ± 0.19 kg at weaning (P < 0.05). Most of the micro- and macroscopic measures such as length and weight of ileum and colon, cervix and uterus, luminal size of cervix and uterus, number of cervical crypts and uterine glands, were greater in gilts with high colostrum intake. The histological architecture of the uterus and cervix in gilts with high colostrum intake showed more complexity, reflecting more advanced development in these piglets. In conclusion, these data demonstrate that independent of birth weight, natural variation in colostrum intake is related to the overall development of neonatal piglets, affecting body growth, as well as growth and development of the gut and reproductive tract.

Abstract
PURPOSE Surgical interventions tend to have an effect on the generation of recurrences in tumor patients due to the anesthesia involved as well as tissue damage and subsequent inflammation. This can also be found in patients with breast cancer. METHODS In this multicenter study, we investigated data of 632 patients with breast cancer and the subsequent diagnosis of a recurrence. The patient data were acquired from 1 January 2006 to 31 December 2019 in eight different centers in Germany. The data sets were separated into those with primary surgery, primary systemic therapy with subsequent surgery, and reconstructive surgery. Three different starting points for observation were defined: the date of diagnosis, the date of first surgery, and the date of reconstructive surgery, if applicable. The observational period was divided into steps of six months and maxima of recurrences were compared. Furthermore, the variance was calculated using the difference of the distribution in percent. RESULTS The descriptive analysis showed no resemblance between the groups. The variance of the difference of the recurrence rates analysis using the surgical date as the starting point showed similarities in the age subgroup. CONCLUSION Our clinical analysis shows different metastatic behavior in different analysis and treatment regimes. These findings justify further investigations on a larger database. These results may possibly identify an improved follow-up setting depending on tumor stage, biology, treatment, and patient factors (i.e., age, …).

Abstract
Abstract
Background
Tumor cell extensions called tumor microtubes (TMs) in glioma resemble neurites during neurodevelopment and connect glioma cells to a network that has considerable relevance for tumor progression and therapy resistance. The determination of interconnectivity in individual tumors has been challenging and the impact of tumor cell connectivity on patient survival remained unresolved so far.
Material and Methods
A connectivity signature was derived by single-cell RNA-sequencing (scRNA-Seq) of highly and lowly connected cells obtained from an SR101 dye transfer xenograft model of primary glioblastoma (GB). The signature was validated in different in vitro models of cell-to-cell connectivity and could be translated to GB clinical specimens.
Results
34 of 40 connectivity genes were related to neurogenesis, neural tube development or glioma progression, including the TM-network-relevant GAP43 gene. Astrocytic-like and mesenchymal-like GB cells had the highest connectivity signature scores in scRNA-Seq data of patient-derived xenografts and patient samples. In 230 human GBs, high connectivity correlated with the mesenchymal expression subtype, TP53 wildtype, and with dismal patient survival. CHI3L1 was identified and validated as a robust molecular marker of connectivity with a functional relevance.
Conclusion
The connectivity signature gives novel insights into brain tumor biology, provides a proof-of-principle that tumor cell connectivity is relevant for patients’ prognosis, and serves as a robust biomarker that can be used for future clinical trials

Abstract
Abstract
Background
Histone 3 lysine27-to-methionine mutations (H3-K27M) frequently occur in childhood diffuse midline gliomas (DMGs) of the pons, thalamus and spinal cord, presumed to be driven by the specific spatiotemporal context of these midline locations during postnatal development. While most common in the pons and at mid-childhood ages, the same oncohistone mutation is recurrently detected in adult DMGs and throughout different midline regions. The potential heterogeneity of tumors at different ages and in different anatomical locations of the midline are vastly understudied.
Material and Methods
Through dissecting the transcriptomic, epigenomic and spatial architectures of a comprehensive cohort of patient H3-K27M DMGs - spanning the age range from 2-68 years and locations from spinal cord to thalamus - at single cell resolution, we delineate how age- and location-dependent contexts shape glioma cell-intrinsic and -extrinsic features in light of the shared driver mutation.
Results
We identify that oligodendrocyte precursor (OPC)-like cells constitute the stem-like compartment in H3-K27M DMGs across all clinico-anatomical groups, however, depending on location, display varying levels of maturity resembling less differentiated pre-OPCs or more mature OPCs further differentiated along the oligodendroglial lineage. We further demonstrate increased mesenchymal cell states in adult tumors, which we link to age-related differences in glioma-associated immune cell compartments. We for the first time resolve the spatial organization of H3-K27M DMG cell types in intact patient tissues, identifying a local niche of the oligodendroglial lineage.
Conclusion
Our study provides a powerful resource for rational modeling and therapeutic frameworks taking into account determinants of age and location in this lethal glioma group.

Abstract
BACKGROUND Predict Breast (www.predict.nhs.uk) is an online prognostication and treatment benefit tool for early invasive breast cancer. The aim of this study was to incorporate the prognostic effect of progesterone receptor (PR) status into a new version of PREDICT and to compare its performance to the current version (2.2). METHOD The prognostic effect of PR status was based on the analysis of data from 45,088 European patients with breast cancer from 49 studies in the Breast Cancer Association Consortium. Cox proportional hazard models were used to estimate the hazard ratio for PR status. Data from a New Zealand study of 11,365 patients with early invasive breast cancer were used for external validation. Model calibration and discrimination were used to test the model performance. RESULTS Having a PR-positive tumour was associated with a 23% and 28% lower risk of dying from breast cancer for women with oestrogen receptor (ER)-negative and ER-positive breast cancer, respectively. The area under the ROC curve increased with the addition of PR status from 0.807 to 0.809 for patients with ER-negative tumours (p = 0.023) and from 0.898 to 0.902 for patients with ER-positive tumours (p = 2.3 × 10-6) in the New Zealand cohort. Model calibration was modest with 940 observed deaths compared to 1151 predicted. CONCLUSION The inclusion of the prognostic effect of PR status to PREDICT Breast has led to an improvement of model performance and more accurate absolute treatment benefit predictions for individual patients. Further studies should determine whether the baseline hazard function requires recalibration.

Abstract
BACKGROUND This study examined 5-year overall, recurrence and distant metastasis-free survival (OS, RFS, MFS) of high- and intermediate-risk breast cancer (BC) patients who declined guideline-recommended adjuvant chemotherapy (CHT). METHODS In the prospective multicenter cohort study BRENDA II, patients with primary BC were sampled over a period of four years (2009-2012). A multi-professional team (tumorboard) discussed recommendation for adjuvant CHT according to the German guideline. Potential differences in 5 year survival were analyzed using Kaplan-Meier curves and Cox regression. The hazard ratios (HR) were adjusted for age, Charlson Comorbidity Score, American Society of Anesthesiologist (ASA) physical status classification, and endocrine therapy. RESULTS A total of 759 patients were enrolled of which 688 could receive CHT according to the guidelines (n = 219 had a clear indication, in n = 304 it was possible). For 360 patients, the tumorboard advised to perform CHT, for 304 it advised against and in 24 cases, no decision was documented. Of those with a positive suggestion, 83% received CHT. Until 5 years after diagnosis, 57 patients were deceased, 41 had at least one distant metastasis and 29 a recurrence. There was no evidence for differences in OS and MFS in patients who declined CHT despite tumorboard recommendation (HR 3.5, 95% CI 0.8-15.1 for OS, HR 1.9, 95% 0.6-6.6 for MFS). Patients who received CHT had significantly better 5-year RFS compared to those who declined (HR 0.3, 95% CI 0.1-0.9, p = 0.03). There was no evidence for different survival in those who had no CHT because of comorbidity and those who declined actively, neither for OS, MFS nor RFS. CONCLUSION The prospective BRENDA II study demonstrates benefit in RFS by guideline adherence in adjuvant breast cancer treatment, indicating prospectively the value of internationally validated guidelines in breast cancer care.

Immediate dental and skeletal influence of distractor position on surgically assisted rapid palatal expansion with or without pterygomaxillary disjunction. Int J Oral Maxillofac Surg 2020; 50:649-656.

Abstract
The outcome of surgically assisted rapid palatal expansion (SARPE) can be affected by pterygomaxillary disjunction (PMD) and the distractor position. In this study, SARPE was performed, with or without PMD, in 20 fresh cadaver heads. Transverse expansion was conducted twice using a bone-borne distractor in the anterior and posterior positions, resulting in four groups (n=10). Cone beam computed tomography scans were completed before and after SARPE to evaluate maxillary changes. A comparative anterior decrease and posterior increase in midpalatal opening resulted from SARPE with PMD combined with a posteriorly placed distractor. Significant differences in the internal transverse changes were found between the two SARPE techniques combined with an anterior distractor at the level of the premolars and molars for alveolar ridge width (P=0.040, P=0.024), and at the level of the molars for the dental crown width (P=0.017) and corresponding tooth cusp width (P=0.018). In contrast, using a posteriorly placed distractor led to a significant difference for tooth cusp width only (P=0.050). No statistically significant differences were found between external transverse changes or between distractor positions. PMD is more important in achieving a more uniform and parallel transverse expansion pattern than the distractor position. However, a posterior distractor seems to intensify the effects of PMD.

Abstract
Influenza encephalopathy, a rare manifestation of influenza infection in the adult population which is not widely recognised, can present with confusion and focal neurological symptoms, including aphasia. The aim of this report is to illustrate the unique presentation of influenza encephalopathy and discuss the need for close attention to and monitoring of this rare but highly fatal disease.A 28-year-old woman was admitted with acute-onset confusion and incoherent speech. CT of the head was unremarkable. Cerebrospinal fluid analysis showed elevation of protein, but was otherwise unremarkable. A detailed history revealed recent upper respiratory symptoms which prompted a rapid influenza test which was positive and oseltamivir was started. The patient's confusion and aphasia gradually improved and her speech was back to her baseline by the next day.

Abstract
Background Patient safety is a key target in public health, health services and medicine. Communication between all parties involved in gynecology and obstetrics (clinical staff/professionals, expectant mothers/patients and their partners, close relatives or friends providing social support) should be improved to ensure patient safety, including the avoidance of preventable adverse events (pAEs). Therefore, interventions including an app will be developed in this project through a participatory approach integrating two theoretical models. The interventions will be designed to support participants in their communication with each other and to overcome difficulties in everyday hospital life. The aim is to foster effective communication in order to reduce the frequency of pAEs. If communication is improved, clinical staff should show an increase in work satisfaction and patients should show an increase in patient satisfaction. Methods The study will take place in two maternity clinics in Germany. In line with previous studies of complex interventions, it is divided into three interdependent phases. Each phase provides its own methods and data. Phase 1: Needs assessment and a training for staff (n = 140) tested in a pre-experimental study with a pre/post-design. Phase 2: Assessment of communication training for patients and their social support providers (n = 423) in a randomized controlled study. Phase 3: Assessment of an app supporting the communication between staff, patients, and their social support providers (n = 423) in a case-control study. The primary outcome is improvement of communication competencies. A range of other implementation outcomes will also be assessed (i.e. pAEs, patient/treatment satisfaction, work satisfaction, safety culture, training-related outcomes). Discussion This is the first large intervention study on communication and patient safety in gynecology and obstetrics integrating two theoretical models that have not been applied to this setting. It is expected that the interventions, including the app, will improve communication practice which is linked to a lower probability of pAEs. The app will offer an effective and inexpensive way to promote effective communication independent of users’ motivation. Insights gained from this study can inform other patient safety interventions and health policy developments.

Abstract
AIMS We conducted a statewide online survey to understand public knowledge, attitudes, and practices (KAP) related to non-pharmaceutical interventions (NPIs) for mosquito-borne diseases and influenza in Arizona. METHODS The survey included knowledge of diseases, major health concerns, and sources of health information and KAP of NPIs for influenza and mosquito-borne diseases. Our team worked with Qualtrics®, an online survey company, to recruit a representative sample of 1500 adults in Arizona. RESULTS Of the 1531 respondents who completed the survey, most indicated that chronic conditions were their primary health concern (48%), with the other half split between infectious diseases (25%) and health effects of environmental conditions (26%). The majority (88%) of respondents indicated that they use the Internet to get their health information. Approximately one in eight people reported not emptying standing water and reducing potential mosquito habitats, despite respondents citing them as being the most effective factors in reducing mosquitoes. Regarding specific diseases, about half of the respondents were concerned about West Nile virus and/or Zika virus. Most (85%) people knew the signs and symptoms of influenza and 63% of people reported being likely to get the influenza shot. Those who did not vaccinate (n = 285) reported concerns that the vaccine would make them sick (41%), was ineffective (37%), or others indicated, 'I don't want to' (37%). CONCLUSIONS Overall, respondents were most concerned with chronic conditions and received their information from the Internet. Knowledge about mosquito-borne diseases was low. There were high levels of acceptance and self-reported uptake of the influenza vaccine.

Abstract
Abstract
Background:
Further progress in the treatment of breast cancer will likely come from contributions of molecular biology and immunologic approaches. The search for druggable molecular aberrations may enable treatment based on the molecular profile. A better identification of patients with a high risk of relapse facilitates the selection of these pts for clinical trials investigating early therapeutic molecular-based interventions.
Trial Design:
The BRandO BiO Registry is a multi-center regional registry to record clinical, epidemiological, and biological data from patients with newly diagnosed breast and ovarian cancer at the University of Ulm, Dept. of Gynecology and 19 affiliated network hospitals and practices in the Alb-Allgäu Bodensee region (outreach area of the Comprehensive Cancer Center Ulm). Longitudinal biobanking is included with collection of paraffin-embedded samples of the primary tumor as well as blood samples at first diagnosis, after 6 and 12 months and at first relapse to isolate and investigate cell-free and germline DNA. Epidemiological, life style and quality of life (QOL) questionnaires are collected at first diagnosis, after 12, 36 and 60 months. The follow up is planned for 10 years.
Eligibility criteria:
Patients with primary newly diagnosed untreated breast or ovarian cancer of ≥ 18 years are eligible; primary metastatic untreated disease is allowed. Exclusion criteria comprise severe neurological or psychiatric disorders interfering with the ability to give an informed consent, no consent for registration, storage and processing of the individual disease characteristics and bio samples, and any malignant tumor in the last 3 years (except in situ disease).
Specific aims:
To register the majority of patients with newly diagnosed breast or ovarian cancer in all BRandO-BiO participating centers of a well-defined geographical area. To assess clinical characteristics and outcome data (event-free survival, overall survival) of these patients. To evaluate the primary tumor of all patients for mutational (druggable) aberrations. Further to assess cell-free DNA in the serial blood samples at baseline, 6 and 12 months and correlate these results with clinical outcome data as well as tumor and patient characteristics to look for early markers predicting relapse. To perform a longitudinal assessment of the patients' sociodemographic factors, comorbidities, lifestyle and QOL factors by analyzing serial questionnaires collected at recruitment and at 12, 36 and 60 months.
Present accrual and target accrual:
The BRandO BiO Registry started January 2016 in the Dept. of Gynecology, University of Ulm and February 2017 at the network hospitals and practices. Until June 2018, 1180 patients with primary breast or ovarian cancer have been enrolled. The current adherence to serial blood testing and serial questionnaires is good with a return rate of 90%. A sample size of 3000 patients is planned.

Abstract
Background and context: The McGrath Foundation has created an e-Learning course to upskill breast care nurses in current metastatic breast cancer practice. The e-Learning course has supported better specialist knowledge and helped close the gap in metastatic cancer support services across Australia. Aim: The project aimed to deliver specialist training to breast care nurses on current trends in care and treatment of individuals with metastatic breast cancer, via an e-Learning platform to enable a cost effective delivery across Australia to 119 nurses. Strategy/Tactics: Key learning outcomes were developed to ensure specific information could be delivered via an online platform. Industry experts, clinicians and experienced breast care nurses/nurse practitioners were consulted to develop the content and an outline of what would be delivered. An experienced online content development company was also engaged to ensure that the content would be presented in an engaging way. Program/Policy process: The metastatic e-Learning course was available for McGrath Breast Care Nurses in June 2017 and accredited for professional development hours by the Australian College of Nursing to contribute to registration under the Nursing and Midwifery Board of Australia. Certificates of completion are given to all participants who successfully complete the course once they achieve competency in all areas of assessment. Outcomes: The e-Learning course has had reach across all areas of the country and allowed easy dissemination of information on current trends in metastatic breast cancer to nurses. This is seen to have great reach with almost all McGrath Breast Care Nurses also caring for a proportion of patients with metastatic disease. Additional qualitative and quantitative analysis will be available during the presentation after analysis is completed. What was learned: Some key learnings from this project have been the scalability of e-Learning as a technology enabled professional development solution. The need for good design to enable engagement with content was consistent theme during feedback sessions. As well as using competency based testing to enable participants to gain professional development in a technology enabled platform has reduced nurse down time.

Abstract
INTRODUCTION: Survival in gastric cancer is often limited by peritoneal carcinomatosis, which supposedly develops from serosal tumor infiltration or tumor cell spread during gastrectomy with lymphadenectomy. To eliminate peritoneal tumor cells, extensive intraperitoneal lavage (EIPL) has been suggested. Impressive results have been achieved in Japanese trials. In this trial, we assessed EIPL in Western patients. METHODS: This prospective trial included patients with non-metastatic gastric adenocarcinoma undergoing gastrectomy with D2 lymphadenectomy. Peritoneal fluid samples at laparotomy, after lymphadenectomy, and after EIPL were analyzed for tumor cells using cytology and EpCAM antibodies. The primary endpoint was peritoneal conversion rate (PCR; proportion of patients in whom EIPL eliminated tumor cells after lymphadenectomy). Secondary endpoints were peritoneal release rate (PRR; proportion of patients with peritoneal tumor cells after gastrectomy/lymphadenectomy among all patients without cells before gastrectomy/lymphadenectomy) and prevalence of peritoneal tumor cells before resection. EIPL was considered ineffective if PCR ⩽ 0.2 and warranted further exploration if PCR ⩾ 0.5. Clinicaltrials.gov identifier is NCT01476553. RESULTS: The trial was stopped early because tumor cells after gastrectomy/lymphadenectomy were detected in only 3/27 (11.1%) patients. In none of these did EIPL eliminate tumor cells (PCR 0, 95% confidence interval [CI] 0%-12.5%). In 8/27 (29.6%) patients, tumor cells were detected after EIPL. PRR was 11.1% (95% CI 2.4%-29.2%). There were no perioperative complications higher than Clavien-Dindo grade 3a. CONCLUSIONS: In Western patients, free peritoneal tumor cells after gastrectomy with D2 lymphadenectomy for gastric cancer were detected only sporadically. Although based on few cases, the findings suggest that EIPL spreads tumor cells into the peritoneal cavity, thus being potentially harmful. Therefore, EIPL cannot be generally recommended.

Abstract
PURPOSE The purpose of this study is to describe current diabetes education practice and specific interventions and responsibilities of diabetes educators in the United States. METHODS The 2008 National Practice Survey (NPS) instrument consisted of 53 items addressing diabetes education program structure, processes and interventions, outcomes and quality improvement activities, and the chronic care model. The survey was hosted online for American Association of Diabetes Educators (AADE) members. Participants totaled 2447 members, constituting a 25% return rate. Data from the 2008 NPS were analyzed and compared with results from previous surveys. RESULTS Nearly two-thirds of respondents in 2008 provided diabetes education in a single location, most commonly in a clinical outpatient/managed care setting (39%). Most programs provided comprehensive services. Managers noted that 42% of their programs were either cost/revenue neutral or profitable. Programs varied in types of services, number of patient visits, team member functions, time spent on services, and instructional methods used. At least 50% of managers said their programs report outcome data, and 88% participate in quality/performance improvement activities. Nearly two-thirds of respondents were unfamiliar with the AADE-adopted chronic care model. CONCLUSIONS Many 2008 NPS results concur with those obtained in 2005 through 2007. Areas of variability among programs suggest a need for standardized interventions and practice guidelines. Educators are encouraged to report outcomes to elucidate the contributions of their programs to patient care. AADE can use the results and comparative data obtained from the 2008 survey when developing practice, research, and advocacy activities.

Abstract
Challenging animals with a demanding situation they are able to cope with and where they are rewarded may be a source of positive emotions and possibly of increased welfare. In order to test if this results in changes of immunological parameters and wound healing, 56 pigs (7-20 weeks of age), housed in groups of 8 animals each, were successfully trained to recognize and localize an individual acoustic summons and to receive a small portion of feed as a reward. Immune reactions and the development of a standardized biopsy wound were compared to values of conventionally fed control groups of equal size and animal-to-feeding-place ratio (2:1). In the experimental animals a significantly higher concentration of IgG as well as an increased in vitro T-cell proliferation to ConA but a reduced LPS-induced proliferation of B-cells was found, while basal salivary cortisol concentrations were similar. Wound development was better in the experimental animals as measured by the area of the inflammatory corona. It decreased more rapidly in the experimental animals since the 5th day after biopsy and was significantly smaller than in the control groups. We conclude that environmental enrichment by equipment provoking attention and cognitive activity which is rewarded by feed may play a beneficial role for physical welfare of intensively housed pigs.

Abstract
The effects of an enriched environment on growth, meat quality, and muscle biological traits were investigated using 64 castrated pigs (age range 7 to 20 weeks). Positive emotional appraisal was induced by a system that acoustically frequently called individuals out of a group (n=32) to a feeding station, where they were rewarded with small portions of feed. The results were compared with traditional fed pigs (Control; n = 32). There was no environmental effect on live weight and lean muscle percentage. However, the stimulating keeping regime reduced the intramuscular fat content of the M. longissimus by 0.2 % and increased the protein content by 0.5 %. Moreover, the drip loss of M. longissimus was 1.1 % lower in the treatment group. The analysis of muscle fibre traits (biopsy samples of M. longissimus) showed a 7 % higher proportion of oxidative muscle fibres in the pigs reared in the enriched environment. This fibre type showed a tendency to increased fibre areas. These findings indicate a higher oxidative capacity of the muscle. However, the activity of the inarker enzyme citrate synthase (CS) was not influenced and the activity of lactate dehydrogenase (LDH) was even increased compared to the control animals.

Abstract
The shot biopsy is a common experimental technique for the collection of samples to investigate muscle tissue characteristics or to determine meat quality features in pigs. Its application seems to be also possible in interdisciplinary research projects investigating animal stress, behaviour, and welfare. The present study on 12 group-housed pigs (age: 12 weeks, weight: 29.3 kg) shows the influence of this wound-causing technique on different humoral and cell-mediated parameters of the immune system at 1, 3, 5, and 9 days after biopsy compared to the initially investigated levels before. An enhancement of the blood sedimentation rate and both the IgG and the cellular immune response in vivo (leukocytes, lymphocytes) as well as in vitro (ConA) was observed. Furthermore, there were signs of a secondary wound infection 5 days after biopsies were taken possibly caused by mutual oral manipulation of the animals. We conclude that the muscle shot biopsy technique can be used on group-housed pigs as a method to investigate muscle physiological characteristics. The technique, however, induces immunological reactions which may interfere with stress-induced immune reactions.

Abstract
OBJECTIVE In order to assess the functional integrity of motor pathways through the corpus callosum (CC) in patients with schizophrenia transcallosally mediated inhibition (TI) of voluntary tonic EMG activity of first dorsal interosseus muscle following ipsilateral focal transcranial magnetic stimulation (fTMS) was investigated. In addition thickness and length of CC were calculated. METHOD Twelve patients suffering from schizophrenia and 12 healthy controls were investigated. CC morphology was measured in mid-sagittal MRI-slices. Latency and duration of TI were calculated. RESULTS In schizophrenics the duration of TI was significantly prolonged, whereas latencies were not. In addition, a lack of TI was found unilaterally in three patients. Measurements of CC revealed a significantly reduction of the length and thickness in the anterior part of CC in patients. CONCLUSION These findings indicate that measurement of TI could be used to detect clinical silent affection of transcallosal motor pathways in schizophrenics. The effect of neuroleptic drugs has to be explored.
