Object. Despite a long and controversial history, psychosurgery has persisted as a modern treatment option for some severe, medically intractable psychiatric disorders. The goal of this study was to review the current state of psychosurgery. Methods. In this review, the definition of psychosurgery, patient selection criteria, and anatomical and physiological rationales for cingulotomy, subcaudate tractotomy, anterior capsulotomy, and limbic leukotomy are discussed. The historical developments, modern procedures, and results of these four contemporary psychosurgical procedures are also reviewed. Examples of recent advances in neuroscience indicating a future role for neurosurgical intervention for psychiatric disease are also mentioned. Conclusions. A thorough understanding of contemporary psychosurgery will help neurosurgeons and other physicians face the ethical, social, and technical challenges that are sure to lie ahead as modern science continues to unlock the secrets of the mind and brain.

Abstract Purpose of Review We critically evaluate the future potential of machine learning (ML), deep learning (DL), and artificial intelligence (AI) in precision medicine. The goal of this work is to show progress in ML in digital health, to exemplify future needs and trends, and to identify any essential prerequisites of AI and ML for precision health. Recent Findings High-throughput technologies are delivering growing volumes of biomedical data, such as large-scale genome-wide sequencing assays; libraries of medical images; or drug perturbation screens of healthy, developing, and diseased tissue. Multi-omics data in biomedicine is deep and complex, offering an opportunity for data-driven insights and automated disease classification. Learning from these data will open our understanding and definition of healthy baselines and disease signatures. State-of-the-art applications of deep neural networks include digital image recognition, single-cell clustering, and virtual drug screens, demonstrating breadths and power of ML in biomedicine. Summary Significantly, AI and systems biology have embraced big data challenges and may enable novel biotechnology-derived therapies to facilitate the implementation of precision medicine approaches.

Abstract Background Disease comorbidity is popular and has significant indications for disease progress and management. We aim to detect the general disease comorbidity patterns in Chinese populations using a large-scale clinical data set. Methods We extracted the diseases from a large-scale anonymized data set derived from 8,572,137 inpatients in 453 hospitals across China. We built a Disease Comorbidity Network (DCN) using correlation analysis and detected the topological patterns of disease comorbidity using both complex network and data mining methods. The comorbidity patterns were further validated by shared molecular mechanisms using disease-gene associations and pathways. To predict the disease occurrence during the whole disease progressions, we applied four machine learning methods to model the disease trajectories of patients. Results We obtained the DCN with 5702 nodes and 258,535 edges, which shows a power law distribution of the degree and weight. It further indicated that there exists high heterogeneity of comorbidities for different diseases and we found that the DCN is a hierarchical modular network with community structures, which have both homogeneous and heterogeneous disease categories. Furthermore, adhering to the previous work from US and Europe populations, we found that the disease comorbidities have their shared underlying molecular mechanisms. Furthermore, take hypertension and psychiatric disease as instance, we used four classification methods to predicte the disease occurrence using the comorbid disease trajectories and obtained acceptable performance, in which in particular, random forest obtained an overall best performance (with F1-score 0.6689 for hypertension and 0.6802 for psychiatric disease). Conclusions Our study indicates that disease comorbidity is significant and valuable to understand the disease incidences and their interactions in real-world populations, which will provide important insights for detection of the patterns of disease classification, diagnosis and prognosis.

The authors describe the main characteristics of Obsessive-Compulsive Disorder, the fourth most frequent psychiatric disease, and Tourette Syndrome. Considered completely separate disorders, there is growing scientific evidence that there is a connection between them. The authors present clinical, genetic and neuroimaging data reinforcing this idea, and call attention to the importance of research in this area, as they believe that the definition of more homogenous subgroups will facilitate the identification of biological markers and predictors of treatment response.

Background. Infertility is becoming ever more pressing a problem by year in Russia and worldwide. Tubal-peritoneal infertility is most frequent, with the prevalence of 42.5-80.5% in various estimates. Echohysterosalpingography is considered the today’s “gold standard” in tubal-peritoneal infertility diagnosis in women. This method is known to possess a series of limitations and adverse consequences due to painful sensations during and after check-ups that psychologically afflict women.Objectives. An overview of current methods for inspecting fallopian tubes in reproductively impaired patients to inform promising diagnostic research.Methods. Publications were mined and analysed in the PubMed, eLibrary, Web of Science, Cochrane Library and Cyberleninka electronic databases. The query terms were: echohysterosalpingography [эхогистеросальпингография], echohysterography [эхогистерография], infertility [бесплодие], pregnancy planning [планирование беременности], fallopian patency [проходимость маточных труб], ultrasonic diagnosis [ультразвуковая диагностика], submucous myomatous node [субмукозный миоматозный узел], incompetent uterine scar [несостоятельный рубец на матке], niche [ниша]. The topic selected was female infertility, particularly, the use of echohysterosalpingography in fallopian diagnosis in reproductively impaired women.Results. The review covers 52 sources of the total 118 analysed. Current published evidence and its review identify a notable success of imaging techniques in the fallopian tube diagnosis in women with reproductive problems. The continually developing echohysterosalpingography technique is considered more promising for routine use. Techniques gain more value in analyses of implantation failures. The main challenges in current radiodiagnosis and monitoring of fallopian lesions at a background therapy are the inspection standardisation, disease classification, imaging diagnostic accuracy and prognostic value evaluation in patients with reproductive loss and infertility.Conclusion. The prospective routes of research comprise the definition of optimal check-up terms, echohysterography and echohysterosalpingography diagnostic criteria descriptiveness, improving prognosis in the carrying of pregnancy and treatment efficacy control. A timely and accurate diagnosis of uterus and fallopian tubes is of paramount importance to sustain the women’s reproductive health.

Abstract Background Neurological forms of Gaucher disease, the inherited disorder of b-Glucosylceramidase caused by bi-allelic variants in GBA1, is a progressive disorder which lacks a disease-modifying therapy. Systemic manifestations of disease are effectively treated with Enzyme Replacement Therapy (ERT), however, molecules which cross the blood-brain barrier are still under investigation. Clinical trials of such therapeutics require robust, reproducible clinical endpoints to demonstrate efficacy and clear phenotypic definitions to identify suitable patients for inclusion in trials. The single consistent clinical feature in all patients with neuronopathic disease is the presence of a supranuclear saccadic gaze palsy, in the presence of Gaucher disease this finding serves as diagnostic of ‘type 3’ Gaucher disease. MethodsWe undertook a study to evaluate saccadic eye movements in Gaucher patients and to assess the role of the EyeSeeCam in measuring saccades. The EyeSeeCam is a video oculography device which was used to run a protocol of saccade measures. We studied 39 patients with non-neurological Gaucher disease (type 1), 21 patients with type 3 (neurological) disease and a series of 35 healthy controls. Mean saccade parameters were compared across disease subgroups. ResultsWe confirmed the saccadic abnormality in patients with type 3 Gaucher disease andidentified an unexpected subgroup of patients with type 1 Gaucher disease who demonstrated significant saccade parameter abnormalities. These patients also showed subtle neurological findings and shared aGBA1 variant. ConclusionsThis striking novel finding of a potentially attenuated type 3 Gaucher phenotype associated with a specific GBA1 variant and detectable saccadic abnormality prompts review of current disease classification. Further, this finding highlights the broad spectrum of neuronopathic Gaucher phenotypes relevant when designing inclusion criteria for clinical trials.

Myocardial infarction with non-obstructive coronary arteries (MINOCA) was first described over 80 years ago. The term has been widely and inconsistently used in clinical practice, influencing various aspects of disease classification, investigation and management. MINOCA encompasses a heterogenous group of conditions that include both atherosclerotic and non-atherosclerotic disease resulting in myocardial damage that is not due to obstructive coronary artery disease. In many ways, it is a term that describes a moment in the diagnostic pathway of the patient and is arguably not a diagnosis. Central to the definition is also the distinction between myocardial infarction and injury. The universal definition of myocardial infarction distinguishes acute myocardial infarction, including those with MINOCA, from other causes of myocardial injury by the presence of clinical evidence of ischaemia. However, these ischaemic features are often non-specific causing diagnostic confusion, and can create difficulties for patient management and follow-up. The purpose of this review is to summarise our current understanding of MINOCA and highlight important issues relating to the diagnosis, investigation and management of patients with MINOCA.

Abstract Background As clinical nurse specialists (CNS), we must be able to support student nurses (SN) and trainee nursing associates (TNA) to help them to develop their professional competencies. We achieve this by offering insight visits to SN/TNA during their placement on our day care unit. SN/TNAs are invited to attend the rheumatology service MDT meeting and then observe the nurse-led clinic. We must ensure there is support and oversight of practice supervision to ensure safe and effective learning. We reviewed the insight visits and asked the SN/TNA to complete a questionnaire. Methods The feedback was analysed and a common theme emerged that they would have liked some pre-visit literature to read prior to attending so they could research rheumatological conditions. When explored; this was due to limited knowledge of conditions. A workbook was developed to focus the SN/TNA on the most common conditions; juvenile idiopathica arthritis (JIA) and uveitis. The workbook was adapted from an education workbook for a new clinical nurse specialist to paediatric rheumatology. It offered a structured and methodical approach to the introduction of JIA and uveitis. It guided them to consider the medical definition of the condition, explore the epidemiology and aetiology of the disease, how a diagnosis is made by the use of investigations, disease classification and the subsequent various treatments available. In concludes by prompting the SN/TNA to consider the various roles within a multidisciplinary team (MDT). The workbook also directs to appropriate websites for information gathering. The workbook is then discussed with the SN/TNA at the end of the visit to ensure they developed better knowledge of rheumatological conditions and the role of the CNS within the service. Results The service continues to ask for feedback from all SN/TNA on insight visits and the feedback on the pre-visit workbook is very positive; “The workbook was definitely helpful because I was able to research about the conditions before coming to the insight visit”- Student Nurse A. The workbook begins the foundation of knowledge which the SN/TNA’s then build upon during the insight visit. Conclusion The paediatric rheumatology service has successfully developed an effective workbook which facilitates SN/TNA’s learning during insight visits to the service. The feedback forms are evidence that the CNS are appropriately supporting SN/TNA’s. The development of this tool has aided the structure of insights visits and essentially improved the quality and learning outcomes for the SN/TNA’s. Conflicts of Interest The authors declare no conflicts of interest.

Background:Difficult-to-treat rheumatoid arthritis (D2T RA) was recently defined by a EULAR study group (1) and, as a disease category it is largely complicated and under-researched. Patient comorbidities may play a significant role in the response to therapy with biologic disease-modifying antirheumatic drugs (bDMARDs) and in the disease classification as D2T RA.Objectives:To evaluate the impact of comorbidities [studied as total Comorbidities Count (CC) and rheumatic disease comorbidity index (RDCI)] on 6-month response to therapy with the first bDMARD in real-world clinical practice and on eventual disease designation as D2T RA.Methods:Prospective study of all RA patients who start any bDMARD in a tertiary centre University Hospital after their consent. All patient comorbidities [among a list of approximately 100 pre-specified major comorbidities] are registered by treating physicians. Response to therapy was defined as achievement of low disease activity or remission (LDA/Rem) according to simplified disease activity index (SDAI) and health assessment questionnaire (HAQ) improvement of ≥ 0.25.D2T RA patient group was defined according to the EULAR definition of D2T RA and was compared to: a/ all other patients and b/ to a sub-group of patients designated as “well-controlled RA” (follow-up ≥2 years and ≥2 visits in the last year in LDA/Rem).Logistic regression models were used to adjust for the potential confounding of age, sex, disease duration, seropositivity, number of previous synthetic DMARDs, type of 1st bDMARD initiated (TNF inhibitor vs. non-TNF inhibitor), co-administered methotrexate and corticosteroids (yes/no), baseline SDAI and HAQ and year of therapy start.Results:Analysis included 501 RA patients who received a total of 1098 bDMARD treatments. At 1st bDMARD treatment start, patients (women: 81%) had a median (IQR) age: 60 (51-68) years, disease duration: 5.4 (3-11) years, SDAI: 36 (28-46), HAQ: 1.0 (0.5-1.5), CC: 3 (2-6) και RDCI: 2 (0-3).In adjusted analyses, total comorbidity count (CC) ≤1 (vs ≥ 2) was predicting LDA/Rem at 6 months of therapy [OR (95%CI) = 4.1 (1.5-11), p=0.005], while RDCI=0 (vs. ≥ 1) was predicting HAQ improvement ≥ 0.25 [OR (95% CI) = 2.6 (1.2-6.7), p=0.046].During 2614 patient-years of follow-up, the disease in 98 patients could be classified as “D2T RA”, while 127 patients had “well-controlled RA”. Baseline independent predictors for D2T RA compared to all other patients were RDCI ≥ 1 (vs. 0) [OR = 3.3 (1.7-9.4), p = 0.024], female sex [OR =3.1 (1.01-9.5)] and age [OR = 0.97 (0.94-0.99)]. Multivariable analyses for predictors of “D2T” compared to “well-controlled” RA yielded similar results.Conclusion:In RA patients starting the first bDMARD treatment, a higher number of comorbidities at baseline is an independent predictor of lower 6-month response to therapy and final disease classification as “difficult-to-treat” RA.References:[1]Nagy G, Roodenrijs NM, Welsing PM, Kedves M, Hamar A, van der Goes MC, et al.
