Fast track open ileo-colic resections for Crohn's disease.

OBJECTIVE: Introduction of multimodal rehabilitation programmes after open colonic surgery for noninflammatory bowel disease has reduced hospital stay to about 2-3 days, but no data are available from open ileo-colic surgery for Crohn's disease with multimodal rehabilitation regimens. Therefore, the aim of study was to assess outcome after ileo-colic resections for Crohn's disease with multimodal rehabilitation. MATERIALS AND METHODS: Thirty-two consecutive ileo-colic resections for Crohn's disease in 29 patients received epidural analgesia and enforced postoperative oral nutrition and mobilization with a scheduled stay of 2 days. RESULTS: Median time to defaecation was 2.5 days and postoperative hospital stay was 3 days. During a 30-day postoperative follow-up there was two re-admissions, one for mechanical bowel obstruction (9 days) and one because of fever and vomiting (6 days). Except for one wound abscess, one cystitis and one pneumonia, no other complications occurred. CONCLUSION: Fast-track multimodal rehabilitation in open ileo-colic resections for Crohn's disease reduces hospital stay and with low morbidity and readmission rate.

Tamoxifen as a potential treatment of glioma.

Cerebral gliomas have a poor survival time even after multimodal treatment, because of the unavoidable recurrence of tumor. Several trials with a combination of old and new chemotherapics have been performed, but survival time remains generally less than 12 months. Tamoxifen (TAM) has recently been shown to inhibit the growth rate of established and low-passage human glioma cell lines. Furthermore, this drug has enabled stabilization of the clinical and radiographic picture in selected patients with recurrent glioma. Here we review published data to discuss a potential role of TAM in the multimodal postoperative treatment of cerebral gliomas.

[Heart-diabetes-network--a concept for improved care for diabetic cardiovascular patients following cardiac surgical intervention].

Diabetic patients with heart disease are high risk patients for further vascular complications and therefore need an intensive and multimodal, interdisciplinary intervention. Due to the "segmentation" of medical care into primary care physician, specialists, acute and secondary care (rehabilitation) clinics, the patients will be taken care of on each individual segment with regard to the current requirements and specialties of the care provider. Such--each section, the GP, the cardiologist and the diabetologist, the heart centre and the rehabilitation clinic, represent individual and often strictly separate segments, which each will focus only on the acute problem and will collect (only) data required for the care in their particular segment. A multimodal approach can improve the chronic care and prognosis of these patients, as shown in several studies. The proposed network model should increase multi-disciplinary cooperation of the different levels of health care segments and overcome current barriers. It is thus necessary to provide common guidelines for diagnostic and therapeutic procedures and to improve communication between each individual sector. This could help to improve the secondary prevention in these high risk patients.

Multimodality intraoperative neurophysiologic monitoring findings during surgery for adult tethered cord syndrome: analysis of a series of 44 patients with long-term follow-up.

STUDY DESIGN: Prospective analysis of a consecutive series in which multimodality intraoperative neurophysiologic monitoring was used as an adjunct to microneurosurgery for adult tethered cord syndrome. The results of multimodality intraoperative neurophysiologic monitoring were compared with the "gold standard" (neurologic outcomes). OBJECTIVE: To assess the sensitivity, specificity, and positive and negative predictive values of multimodality intraoperative neurophysiologic monitoring in surgery for adult tethered cord syndrome. SUMMARY OF BACKGROUND DATA: Although intraoperative electrophysiologic techniques may help to minimize neural injury during spinal microneurosurgery, to our knowledge, no study has quantitatively evaluated the value of multimodality intraoperative neurophysiologic monitoring in the management of adult tethered cord syndrome. METHODS: Multimodality intraoperative neurophysiologic monitoring included posterior tibial nerve somatosensory evoked potentials (SSEPs), continuous electromyographic (EMG) monitoring of the L2 to S4 myotomes, and evoked EMG. Follow-up neurologic evaluations were performed for at least 1 year. RESULTS: A total of 44 consecutive patients, including 19 males and 25 females (aged 43 +/- 15 years), who underwent microsurgery for adult tethered cord syndrome were evaluated. After surgery, new neurologic deficits, including 1 transient and 1 permanent, developed in 2 patients. There was 1 patient who had persistent posterior tibial nerve SSEP amplitude reduction following microsurgical manipulation. In 1 patient, a transient posterior tibial nerve SSEP amplitude reduction prompted a change in microneurosurgical strategy. This patient awoke with no new postoperative neurologic deficits. For SSEPs, the sensitivity was 50% and specificity 100%. EMG bursts were recorded in 36 patients (82%). The 2 patients with postoperative neurologic worsening had EMG activity in the myotomes, where their new deficits presented. Continuous EMG had a sensitivity of 100% and a specificity of 19%. CONCLUSIONS: To our knowledge, this is the largest series to date reporting the use of multimodality intraoperative neurophysiologic monitoring in the surgical management of adult tethered cord syndrome. Posterior tibial nerve SSEPs have high specificity, but low sensitivity, for predicting new neurologic deficits. In contrast, continuous EMG showed high sensitivity and low specificity. Evoked EMG accurately identified functional neural tissue. The combined recording of SSEPs in concert with continuous and evoked EMGs may provide a useful adjunct to complex microsurgery for adult tethered cord syndrome.

Neoadjuvant chemoradiation may increase the risk of respiratory complications and sepsis after transthoracic esophagectomy.

BACKGROUND: The role of neoadjuvant chemotherapy and radiation therapy before resection in esophageal cancer remains controversial. Operative risks may be increased, but this has not been systematically addressed in published trials or reports. METHODS: This was a prospective, nonrandomized, restricted cohort design of patients (n = 200) from 1997 to 2003 with resectable cancer of the esophagus or esophagogastric junction. A total of 102 patients underwent multimodal therapy with 5-fluorouracil, cisplatin, and radiation therapy before surgery, and 98 patients opted for surgery alone. In-hospital mortality and morbidity were the primary end points, and cancer survival was a secondary end point. RESULTS: In patient cohorts matched for operative risk factors, the odds ratio for postoperative sepsis (P = .007), respiratory failure (P = .009), and acute respiratory distress syndrome (P = .02) was increased in the multimodal group. There was no significant difference between groups comparing median and 1-, 2-, and 3-year survivals. CONCLUSIONS: Multimodal therapy was associated with increased respiratory and septic complications compared with a surgery-only cohort undergoing the equivalent surgery. Respiratory failure was in most cases idiopathic. The data suggest that efforts should be made to limit radiation lung exposure in multimodal regimens, and to understand and modulate the local and systemic effects of preoperative chemoradiation.

Triage and workflow optimization with artificial intelligence in pediatric imaging.

Artificial intelligence (AI) is being increasingly utilized in various aspects by the radiology department. With an ever-increasing burden on the healthcare system, particularly in emergency units, the need to incorporate AI in patient triage and workflow optimization cannot be overstated. Machine learning (ML)-based algorithms form the core of AI-based software, aiding healthcare professionals at nearly every step in delivering appropriate patient care. Regarding the radiology section of the hospital, AI-based algorithms have proven exceptionally useful in assisting radiologists and technicians with image acquisition. From accurate clinical referrals to scheduling computed tomography/magnetic resonance imaging scan appointments, from ensuring the lowest radiation exposure to offering timely follow-up reminders, ML-based software has indeed revolutionized the concept of modern image acquisition, especially in the pediatric radiology section. Although the implementation of these algorithms is swift, several technical challenges and the limited availability of pediatric datasets preclude their widespread use. The utility of multimodal pediatric datasets, which combine imaging, genomics, and clinical data, for comprehensive AI triage models can help AI systems evolve toward greater adaptability and integration, resulting in enhanced efficiency, reduced turnaround times, and improved patient outcomes in pediatric radiology departments in the future. In this article, we highlight and review the utility of AI and machine learning-based algorithms in efficiently aiding triage and streamlining the workflow in the pediatric radiology section, thereby ensuring an overall improvement in the departmental workflow.

Oral melanoma in the immunotherapy era: Immune evasion, resistance, and therapeutic opportunities.

Oral melanoma (OM) is a rare and highly aggressive mucosal malignancy associated with poor survival and limited evidence to guide immunotherapy. This narrative review synthesizes current knowledge on OM immunobiology and its therapeutic implications. OM differs from cutaneous melanoma in its origin in sun-protected sites, genomic architecture, and heterogeneous immune microenvironments, features that can contribute to attenuated responses to immune checkpoint inhibitors. Anti-PD-1-based therapy has demonstrated clinical activity in mucosal melanoma, and selected OM cases have shown meaningful responses, including in multimodal and perioperative settings. However, OM-specific prospective data remain sparse, and the available evidence is largely derived from pooled mucosal melanoma cohorts or case reports. Emerging combination strategies, such as antiangiogenic agents, radiotherapy, and perioperative immunotherapy, remain insufficiently validated. This review critically reappraises the available evidence, identifies key knowledge gaps, and outlines future directions for biomarker-driven, OM-specific translational research.

Managing pain in feline patients.

In the past 10 years, great strides have been made in the field of feline analgesia. A better understanding of the cat's unique metabolism has led researchers to realize that extrapolation across species boundaries is unwise,and this has resulted in feline-specific studies. The opioids are now used more commonly in cats, with good analgesic effect and few side effects. Excellent acute pain management is achievable in cats by using opioids, NSAIDs, alpha2-agonists, and local anesthetics. Although much of the research data has compared the use of single drugs, a multimodal approach using agents that work at different parts of the pain pathway is commonly used in clinical settings, with added benefit. Compared with dogs, few pain-scoring systems have been developed for cats, and this remains an important goal. Management of chronic pain in cats is a challenge because of the potential problems with long-term NSAID use; however, reports of low doses given at extended intervals are encouraging. As we gain experience with less traditional analgesics, such as amitriptyline, amantadine, and gabapentin, and critically evaluate complimentary therapies, our ability to provide comfort to this population of cats will improve.

Electromyographic biofeedback can improve subjective and objective measures of fecal incontinence in the short term.

Electromyographic biofeedback therapy has demonstrated subjective improvement in patients with fecal incontinence that is comparable to surgery. We assessed the efficacy of biofeedback therapy in a consecutive heterogeneous group of patients using both subjective and objective assessment criteria. These 28 patients with fecal incontinence were studied retrospectively. Patients were assessed using a quality-of-life questionnaire (QOL), the Vaizey and Wexner incontinence scoring systems, and anorectal manometry for efficacy of treatment, before and after biofeedback therapy. Eighty-six percent of patients completed the study. Median follow-up was 18 months. Eighty percent of patients demonstrated significant improvements in their Vaizey and Wexner scores (P<0.001 and P<0.001, respectively). The mean QOL score improved from 62 to 77 (P<0.01). Significant improvements were also demonstrated in the mean resting pressure (P<0.01), peak amplitude of squeeze (P<0.01), and the duration of squeeze pressure (P<0.05). The deferred 15-minute evacuation time also significantly increased (P<0.001). This study reported significant short-term improvement in fecal incontinence with electromyographic biofeedback therapy using validated subjective and objective scoring systems. Similarly, this treatment also significantly improved anorectal manometric findings. Our data confirm the role of biofeedback therapy in the multimodality approach to patients with fecal incontinence.

[Clinical impact of locoregional hyperthermia in gynecological oncology].

In the last decade progress in gynecological oncology has been achieved mainly by new cytotoxic drugs and advances in radiation technology. For example, the use of taxanes in the primary therapy of ovarian cancers and of combined radio-chemotherapy in cervical cancer has led to significant prolongations of survival. However, in case of relapse most gynaecological malignancies are associated with very poor prognosis. Efficacy of local and systemic therapy can be increased by combining radiotherapy and/or chemotherapy with locoregional hyperthermia (LRH). Increasing the temperature of the target tissue up to 41-43 degrees C leads to local hyperaemia and the tumor tissue becomes more responsive to cytotoxic interventions. In several prospective randomized studies the combination between LRH and radiotherapy was superior to radiotherapy alone in terms of local control (e. g. chest wall recurrence in breast cancer) and has led to longer overall survival in advanced cervical cancer. Platinum derivatives and other cytotoxic drugs have shown synergistic effects with LRH and the combination of both has elicited high response rates in recurrent cervical cancer. In phase-II-clinical trials the newly developed liposomal anthracyclines demonstrated synergistic effects with LRH in patients with refractory ovarian cancer. Our own experience has shown that adding LRH to radio- and/or chemotherapy is well tolerated by the patients. Despite of the fact, that the available data are still preliminary, the inclusion of LRH into multimodal cancer therapy concepts appears to be very promising. Well-designed comparative studies are still needed to evaluate the role of hyperthermia as an adjunct to conventional cancer therapy.

Prerequisites for lack of age differences in memory performance.

Free recall performance of young and old adults was examined in three memory tasks: acts carried out by the subjects (subject-performed tasks or SPTs), sentences with imagery instructions, and sentences. The subjects were presented with the same verbal information in all three tasks. No age differences were observed on free recall of SPTs, whereas typical aging effects were obtained on free recall of the other tasks. This way the data from a previous study of no age effects on SPT recall were replicated. A hypothesis about imagery as a critical factor for the lack of age differences on SPT recall gained no support. Two main concepts were proposed to account for the data: Compensation among the elderly by means of the multimodal and rich properties of SPTs, and a superior ability for a spontaneous recoding of verbal information among young adults. The results were also discussed in relation to a presumption of memory tasks as varying in attentional demands.

Integrating Imaging-Derived Clinical Endotypes with Plasma Proteomics and External Polygenic Risk Scores Enhances Coronary Microvascular Disease Risk Prediction.

Coronary microvascular disease (CMVD) is an underdiagnosed but significant contributor to the burden of ischemic heart disease, characterized by angina and myocardial infarction. The development of risk prediction models such as polygenic risk scores (PRS) for CMVD has been limited by a lack of large-scale genome-wide association studies (GWAS). However, there is significant overlap between CMVD and enrollment criteria for coronary artery disease (CAD) GWAS. In this study, we developed CMVD PRS models by selecting variants identified in a CMVD GWAS and applying weights from an external CAD GWAS, using CMVD-associated loci as proxies for the genetic risk. We integrated plasma proteomics, clinical measures from perfusion PET imaging, and PRS to evaluate their contributions to CMVD risk prediction in comprehensive machine and deep learning models. We then developed a novel unsupervised endotyping framework for CMVD from perfusion PET-derived myocardial blood flow data, revealing distinct patient subgroups beyond traditional case-control definitions. This imaging-based stratification substantially improved classification performance alongside plasma proteomics and PRS, achieving AUROCs between 0.65 and 0.73 per class, significantly outperforming binary classifiers and existing clinical models, highlighting the potential of this stratification approach to enable more precise and personalized diagnosis by capturing the underlying heterogeneity of CMVD. This work represents the first application of imaging-based endotyping and the integration of genetic and proteomic data for CMVD risk prediction, establishing a framework for multimodal modeling in complex diseases.

[Use of calcium antagonists in therapy of bronchial asthma].

A study was made of the therapeutic efficacy of calcium antagonists (CA) in the treatment of bronchial asthma. It has been shown that CA, particularly nifedipine and verapamil, do not exert, in the course of an acute drug test, any significant effect on bronchial patency. At the same time CA produce an appreciable preventive effect when administered to bronchial asthma patients with the syndrome of bronchial tree hyperreactivity--cold and post-exercise bronchospasm. Special attention is drawn to CA synergism with inhalation sympathomimetics, which lies in the increase of the duration of the bronchodilating action of the latter ones. The paper provides the data concerned with the effective use of CA in multimodality treatment of the patients with associated bronchial asthma and coronary heart disease.

Sarcoma of the breast: implications for extent of therapy. The M. D. Anderson experience.

BACKGROUND: Sarcoma of the breast is a rare clinical entity for which there are no prospective data about extent of surgery indicated or role of multimodality therapy. The purpose of this study was to examine one of the largest single institutional experiences to shed light on these clinical issues. METHODS: This study retrospectively reviewed 60 cases of sarcoma of the breast (cystosarcoma phyllodes excluded). RESULTS: For the entire series there was a median overall survival time (OS) of 67 months and a disease-free survival period (DFS) of 18 months. Tumors smaller than 5 cm were associated with a better DFS (p < 0.04) and OS (p < 0.009). Patients with tumors less than 5 cm in diameter did equally well whether treated by wide local excision or mastectomy. Angiosarcoma histologic characteristics were associated with longer OS than stromal sarcoma (p = 0.017), malignant fibrous histiocytoma (p = 0.075), or fibrosarcoma (p = 0.08). Axillary dissections did not recover any nodal metastasis; moreover, treatment in 75% of the patients with negative nodes subsequently failed. Regional lymph node metastases were always and only in the context of disseminated disease. Adjuvant chemotherapy and/or radiotherapy was associated with prolonged DFS (p = 0.015). There was a trend toward improved local control with adjuvant radiotherapy (p = 0.14). CONCLUSIONS: Lesions less than 5 cm should be treated by breast-preserving wide local excision, and adjuvant radiotherapy should be considered for selected subgroups. For tumors 5 cm or larger, a more aggressive approach seems appropriate; consideration should be given to neoadjuvant chemoradiation followed by margin-negative surgery (if possible). There is no demonstrable staging or therapeutic role for routine axillary dissection.

[The role of anesthesiology in fast track concepts in colonic surgery].

In the present study the "fast-track rehabilitation" protocol of the Charité university hospital for patients undergoing elective colonic resection is described. The underlying principles, clinical pathways and outcome data from 208 patients are shown. Particularly anesthesiological aspects of this multimodal approach, such as modified preoperative and postoperative fluid management, changed guidelines for preoperative fasting, effective analgetic therapy using epidural analgesia and avoiding high systemic doses of opioids, use of short-acting anesthetic agents, and maintenance of normothermia as well as normovolemia are presented and discussed. In comparison to outcome data before "fast-track rehabilitation" was established, the duration of postoperative hospital stay has been reduced from 12 to 5 days, the number of general complications (pneumonia, duodenal ulcer bleeding, urinary tract infection, cerebral, cardiac and renal dysfunction) decreased from 20% to 7%, whereas surgical complications remained constant at 17% (8% wound infections, 3% anastomotic insufficiency).

Head and neck soft tissue sarcomas of adult: prognostic value of surgery in multimodal therapeutic approach.

Adult head and neck soft tissue sarcomas (AHNSTS) are rare, and data concerning treatment results are spare. To assess clinico-pathological characteristics, management prognostic factors, and survival of AHNSTS, we reviewed our experience of 28 recent successive new cases. Data were collected from a retrospective database (1997-2002). Aggressive fibromatosis, dermatofibrosarcoma, Kaposi sarcoma, chondrosarcoma and osteogenic sarcoma were excluded. Univariate analysis for prognostic factors was performed with chi2 test with Yates correction. The median age was 45.7 years (range: 18-86). The male/female ratio was 15/13. The most common subtypes was rhabdomyosarcoma (seven cases). Twenty-two patients presented with previous inadequate resection performed elsewhere before admission. The most common location was neck muscles (11 cases). Nineteen patients had surgery (complete resection in 13 cases). Associated treatments were neoadjuvant chemotherapy, adjuvant chemotherapy and postoperative radiotherapy in respectively, 4, 3 and 10 cases. The 2-year overall survival was 56%. Rhabdomyosarcomas (p = 0.005) and inadequate resection (p = 0.04) were associated with poor outcome. Large resection of AHNSTS in a multimodality approach may afford the best chance of disease control.

Population-based analysis of arteriovenous malformation treatment.

OBJECT: The author sought to describe overall management data on cerebral arteriovenous malformations (AVMs) and to focus the actuarial need for different treatment modalities on a population-based scale. Such data would seem important in the planning of regional or national multimodality strategies for the treatment of AVMs. This analysis of a nonselected, consecutive series of patients representing every diagnosed case of cerebral AVM in a population of 1,000,000 over one decade may serve to shed some light on these treatment aspects. METHODS: During the 11-year period from 1989 to 1999, data from every patient harboring a cerebral AVM that was presented clinically or discovered incidentally in a strictly defined population of 986,000 people were collected prospectively. No patient was lost to follow up. There were 12.4 de novo diagnosed AVMs per 1,000,000 population per year (135 AVMs). Large high-grade AVMs (Spetzler-Martin classification) were rare, and Grade 1 to 3 lesions represented 85% of the caseload. Hemorrhage was the initial manifestation of AVM in 69.6% of the cases. lntracerebral hematoma was the most common hemorrhagic manifestation occurring in 78 patients. There were 4.4 cases per 1,000,000 population per year of hematomas needing expedient surgical evacuation. In the remaining patients who did not require hematoma surgery, small, critically located Grade 3 and Grade 4 lesions amounted to 1.6 cases per 1,000,000 population per year. There were 5.8 cases per 1,000,000 population per year of Grade 1 to 2 and larger noncritically located Grade 3 malformations. There were 0.5 cases per 1,000,000 population per year of Grade 5 AVMs. The overall outcome in 135 patients was classified as good according to the Glasgow Outcome Scale (Score 5) in 61% of the cases, and the overall mortality rate was 9%. CONCLUSIONS: In centers with population-based referral, AVM of the brain is predominantly a disease related to intracranial bleeding. and parenchymal clots have a profound impact on overall management outcome. The rupture of an AVM is as devastating as that of an aneurysm. Aneurysm ruptures are more lethal, whereas AVM rupture tends to result in more neurological disability due to the high occurrence of lobar intracerebral hematoma. In an attempt to quantify the need for different modalities of AVM treatment based on a population of 1,000,000 people, figures for surgeries performed range from six to 10 operations per year and embolization as well as gamma knife surgery procedures range from two to seven per year, depending on the strategy at hand. When using nonsurgical approaches to Grade 1 to 3 lesions, the number of patients requiring treatment with more than one method for obliteration increases drastically as does the potential risk for procedure-related complications.

Enterocutaneous Fistula-Associated Sepsis and Mortality: Development and Validation of a Multimodal Artificial Intelligence Prediction Model.

BACKGROUND: Predicting enterocutaneous fistula (ECF)-associated sepsis and mortality poses significant challenges in digital health care due to the disease's complexity and heterogeneous clinical manifestations. Current approaches that rely on single-modal data or traditional scoring systems often fail to capture the intricate immune-inflammatory dynamics and multisystem involvement in patients with ECF. OBJECTIVE: This study aims to develop an artificial intelligence (AI)-driven multimodal fusion model integrating clinical, imaging, and transcriptomic data for early prediction of ECF-associated sepsis and 28-day mortality, addressing the limitations of conventional single-dimensional models. METHODS: This study leveraged publicly available datasets (Medical Information Mart for Intensive Care III [MIMIC-III], electronic Intensive Care Unit [eICU], and The Cancer Genome Atlas) to construct a multimodal framework. Clinical parameters were processed using Extreme Gradient Boosting, abdominal imaging features were extracted via convolutional neural networks, and transcriptomic profiles were analyzed with variational autoencoders. A Transformer-based fusion network was employed for joint prediction and validated through cross-validation and external testing. Key features were identified using Shapley Additive Explanations and Local Interpretable Model-Agnostic Explanations interpretability algorithms, while immune regulatory mechanisms were explored via weighted gene co-expression network analysis. RESULTS: The multimodal model achieved an area under the curve (AUC) of 0.89 for predicting sepsis and 28-day mortality, outperforming unimodal models (clinical-only model, AUC 0.72, and imaging-only model, AUC 0.78). Critical predictors included Sequential Organ Failure Assessment score, lactate levels, intra-abdominal free fluid on imaging, and immunoregulatory genes (programmed death-ligand 1 [PD-L1] and indoleamine 2,3-dioxygenase 1 [IDO1]). Mechanistic analysis revealed distinct immune reprogramming in patients with sepsis, characterized by increased regulatory T cells and M2 macrophages, along with downregulated cluster of differentiation 8+ (CD8+) T cells. CONCLUSIONS: This multimodal AI model offers an innovative digital solution in medical informatics, enabling precise early risk stratification for ECF-associated sepsis. By integrating multisource data and providing interpretable insights into immune-inflammatory pathways, the model enhances health care quality for patients with ECF and paves the way for personalized intervention strategies.
