Sanders classification of calcaneal fractures in CT images with deep learning and differential data augmentation techniques.
Injury, 2021

Classification of the type of calcaneal fracture on CT images is essential in driving treatment. However, human-based classification can be challenging due to anatomical complexities and CT image constraints. The use of computer-aided classification system in standard practice is additionally hindered by the availability of training images. The aims of this study is to 1) propose a deep learning network combined with data augmentation technique to classify calcaneal fractures on CT images into the Sanders system, and 2) assess the efficiency of such approach with differential training methods.
Introducing a Conversational Model Therapy Approach as a Team Model of Care: The Clinician Experience in a Sexual Assault Service.
Issues in mental health nursing, 2018

This article examines clinician experience in adopting a contemporary psychodynamic model of care by exploring the experiences and perspectives of staff at an Australian hospital-based sexual assault service (SAS), reflecting then on implications for how to best engage clinicians in a model of care change and training. The Conversational Model of Therapy (CMT) is a contemporary psychodynamic approach integrating evidence from developmental psychology, neuroscience and trauma. Training was provided in the CMT approach to Short-Term Intensive Psychodynamic Psychotherapy seeking to enable the service to better provide for the needs of adult clients with less recent sexual assault experiences and/or those able to receive a short-term psychotherapy. Five semi-structured individual interviews and one focus group (with four participants) were undertaken to identify SAS staff perceptions of their experiences after initial training of up to 13 sessions with CMT. Thematic analysis was performed to identify, analyse and report patterns in the responses with the following themes emerging: the challenges staff face in providing a service to clients; coping mechanisms staff utilise in their work; the current service structure and how this compares with their experiences of CMT, and; feelings and thoughts on SAS staff being evaluated. Findings provide evidence that the majority of staff understood the need for change and were able to undertake training towards this due to effective coping mechanisms within their work and good support from within their team. The research also highlights the need to ensure effective training to evaluate participants' understanding of the model being taught. In the context of training experience elsewhere, learning and synthesis of all of the knowledge relevant to a psychodynamic model of care may require experiential learning through supervision of audio-recorded sessions, although this has challenges in the SAS context.
Recent genetic advances in early-onset dystonia.
Current opinion in neurology, 2020

The discovery of new disease-causing genes and availability of next-generation sequencing platforms have both progressed rapidly over the last few years. For the practicing neurologist, this presents an increasingly bewildering array both of potential diagnoses and of means to investigate them. We review the latest newly described genetic conditions associated with dystonia, and also address how the changing landscape of gene discovery and genetic testing can best be approached, from both a research and a clinical perspective.
Self-enucleation of the right eye by a 38-year-old woman diagnosed with schizoaffective disorder: a case report.
BMC psychiatry, 2020

Autoenucleation is a rare form of self-mutilation typically associated with psychiatric disorders such as schizophrenia, substance-induced psychosis and bipolar disorder. The act is usually unilateral, although bilateral attempts are also well documented in the literature.
Dyspnea after subthalamic deep brain stimulation in Parkinson's disease: a case-control study.
Journal of neurology, 2020

Dyspnea can be present as non-motor symptom in patients with Parkinson's disease (PD). Deep brain stimulation (DBS) of the subthalamic nucleus (STN) improves motor and non-motor symptoms in PD. However, new-onset dyspnea has been reported after DBS surgery. We have studied respiratory characteristics of PD patients with bilateral STN-DBS to assess the impact of DBS on pulmonary function.
Gastrointestinal alterations in autism spectrum disorder: What do we know?
Neuroscience and biobehavioral reviews, 2020

There is an emerging body of evidence associating children having autism spectrum disorder (ASD) with gastrointestinal (GI) symptoms, such as abdominal pain, chronic diarrhea, constipation, vomiting, gastroesophageal reflux, intestinal infections, and increased intestinal permeability. Moreover, in many studies, large differences in the composition of intestinal microbiota and metabolic products between ASD patients and controls were reported. Deepening the role and the biology of the gut microbiome may be fundamental to elucidate the onset of GI symptoms in ASD individuals and their etiopathogenetic causes. The gut-brain axis may affect brain development and behaviors through the neuroendocrine, neuroimmune, and autonomic nervous systems.

Current biology : CB, 2009

Central neurons receive thousands of synaptic inputs. A recent study shows how pyramidal neurons of the mammalian neocortex integrate synaptic input in a parallel manner, illustrating how a chain of dendritic integration mechanisms act to signal distal dendritic excitatory synaptic input.
Upper and Lower Respiratory Signs and Symptoms in Workers Occupationally Exposed to Flour Dust.
International journal of environmental research and public health, 2020

A group of 142 bakers was studied in order to investigate the relationship between higher/lower respiratory signs/symptoms and inflammation biomarkers and occupational exposure to flour dust. A complete upper and lower respiratory tract evaluation was performed. Seven percent of bakers complained of lower respiratory symptoms, while 22% of them complained of upper respiratory symptoms. Fifty five percent of the bakers were allergic, and 37.1% showed sensitization to occupational allergens. Abnormal spirometries were found in 15% of bakers, while fractional exhaled nitric oxide (FeNO) was above the normal reference in 24.5% of them. Moreover, 23.8% of bakers were found to be hyposmic. Population mean peak nasal inspiratory flow (PNIF) was in the normal range even if almost all the workers suffered from neutrophilic rhinitis at nasal cytology with the number of nasal neutrophils increasing with the increase of the duration of exposure to flour dust (
Neurogenic differentiation of human dental pulp stem cells by optogenetics stimulation.
Journal of chemical neuroanatomy, 2020

Human dental pulp stem cells (hDPSCs), a promising source for autologous transplantation in regenerative medicine, have been shown to be able to differentiate into neural precursors. Optogenetics is considered as an advanced biological technique in neuroscience which is able to control the activity of genetically modified stem cells by light. The purpose of this study is to investigate the neurogenic differentiation of hDPSCs following optogenetic stimulation.

Hypnotizability and the position sense: proprioceptive localization of the hand.
Archives italiennes de biologie, 2015

We  investigated whether healthy subjects with high (highs) and low (lows) hypnotizability scores differ in the ability to report the position of their right hand in the horizontal plane at the end of passive and active arm movements directed to lateral, intermediate and medial targets of the right hemispace under correct or incorrect visual feedback. Results showed that incorrect visual feedback increased the error in both groups. In lows, the error was similar after active and passive movements; in highs, it was lower for active than passive movements toward the medial position, but lower for passive than for active movements for the lateral one. The highs' error was significantly lower than the lows' one only for the active movements directed toward the medial hand position. Hypnotizability-related differences may be due to different role of efferent copies in highs and lows.
Novel Distinctive Roles of Docking Proteins in Short-term Synaptic Plasticity of Frog Neuromuscular Transmission Revealed by Botulinum Neurotoxins.

Short-term synaptic plasticity (SSP) is a basic mechanism for temporal processing of neural information in synaptic transmission. Facilitation, the fastest component of SSP, has been extensively investigated with regard to Ca
Hyperbaric Oxygen as Salvage Therapy for Neonates Suffering From Critical Ischemia of the Glans Penis After Circumcision.
Urology, 2021

Ischemic complications of glans penis following circumcision are rare, and if occurs can culminate in irreversible necrosis with severe long-term consequences. Here we present 2 challenging cases of neonates suffering from acute severe glans penis ischemia after circumcision that were treated by hyperbaric oxygen treatment (HBOT). In addition to case presentations, the literature related to complications of circumcision and the physiological effects of HBOT are being reviewed. Based on the review and the case presented, we conclude that HBOT can be used as salvage treatment for circumcision induced glans ischemia as early as possible before full necrosis develops.
Why behavioral neuroscience still needs diversity?: A curious case of a persistent need.
Neuroscience and biobehavioral reviews, 2020

In the past few decades, a substantial portion of neuroscience research has moved from studies conducted across a spectrum of animals to reliance on a few species. While this undoubtedly promotes consistency, in-depth analysis, and a better claim to unraveling molecular mechanisms, investing heavily in a subset of species also restricts the type of questions that can be asked, and impacts the generalizability of findings. A conspicuous body of literature has long advocated the need to expand the diversity of animal systems used in neuroscience research. Part of this need is utilitarian with respect to translation, but the remaining is the knowledge that historically, a diverse set of species were instrumental in obtaining transformative understanding. We argue that diversifying matters also because the current approach limits the scope of what can be discovered. Technological advancements are already bridging several practical gaps separating these two worlds. What remains is a wholehearted embrace by the community that has benefitted from past history. We suggest the time for it is now.
Assessing the relationship between monoallelic PRKN mutations and Parkinson's risk.
Human molecular genetics, 2021

Biallelic Parkin (PRKN) mutations cause autosomal recessive Parkinson's disease (PD); however, the role of monoallelic PRKN mutations as a risk factor for PD remains unclear. We investigated the role of single heterozygous PRKN mutations in three large independent case-control cohorts totalling 10 858 PD cases and 8328 controls. Overall, after exclusion of biallelic carriers, single PRKN mutations were more common in PD than controls conferring a >1.5-fold increase in the risk of PD [P-value (P) = 0.035], with meta-analysis (19 574 PD cases and 468 488 controls) confirming increased risk [Odds ratio (OR) = 1.65, P = 3.69E-07]. Carriers were shown to have significantly younger ages at the onset compared with non-carriers (NeuroX: 56.4 vs. 61.4 years; exome: 38.5 vs. 43.1 years). Stratifying by mutation type, we provide preliminary evidence for a more pathogenic risk profile for single PRKN copy number variant (CNV) carriers compared with single nucleotide variant carriers. Studies that did not assess biallelic PRKN mutations or consist of predominantly early-onset cases may be biasing these estimates, and removal of these resulted in a loss of association (OR = 1.23, P = 0.614; n = 4). Importantly, when we looked for additional CNVs in 30% of PD cases with apparent monoallellic PRKN mutations, we found that 44% had biallelic mutations, suggesting that previous estimates may be influenced by cryptic biallelic mutation status. While this study supports the association of single PRKN mutations with PD, it highlights confounding effects; therefore, caution is needed when interpreting current risk estimates. Together, we demonstrate that comprehensive assessment of biallelic mutation status is essential when elucidating PD risk associated with monoallelic PRKN mutations.
[Pruritus-a long journey from neurophysiology to the clinic].
Der Hautarzt; Zeitschrift fur Dermatologie, Venerologie, und verwandte Gebiete, 2020

The mutual exchange of results between basic sciences and clinical research as well as their translation into practice, also with regard to chronic pruritus, is currently to be seen as an ambition or hope rather than established practice.
Behavioral and neurophysiological taste responses to sweet and salt are diminished in a model of subclinical intestinal inflammation.
Scientific reports, 2020

There is strong evidence for gut-taste bud interactions that influence taste function, behavior and feeding. However, the effect of gut inflammation on this axis is unknown despite reports of taste changes in gastrointestinal (GI) inflammatory conditions. Lipopolysaccharide (LPS), an inflammatory stimulus derived from gram-negative bacteria, is present in the normal GI tract and levels increase during high-fat feeding and gut infection and inflammation. Recordings from the chorda tympani nerve (CT), which transmits taste information from taste buds on the anterior tongue to the brain, previously revealed a transient decrease in sucrose responses in mice that ingest LPS during a single overnight period. Here we test the effect of acute or chronic, weekly LPS gavage on licking behavior and CT responses. Using brief-access testing, rats treated with acute LPS and mice receiving acute or chronic LPS decreased licking responses to sucrose and saccharin and to NaCl in mice. In long-term (23 h) tests chronic LPS also reduced licking responses to saccharin, sucrose, and NaCl in mice. Neurophysiological recordings from the CT supported behavioral changes, demonstrating reduced responses to sucrose, saccharin, acesulfame potassium, glucose and NaCl in acute and chronic LPS groups compared to controls. Chronic LPS significantly elevated neutrophils in the small intestine and colon, but LPS was not detected in serum and mice did not display sickness behavior or lose weight. These results indicate that sweet and salt taste sensitivity could be reduced even in asymptomatic or mild localized gut inflammatory conditions such as inflammatory bowel disease.
Deep Brain Stimulation for Chronic Cluster Headache: Meta-Analysis of Individual Patient Data.
Annals of neurology, 2020

Deep brain stimulation (DBS) is a treatment option for refractory chronic cluster headache (CCH). Despite several recent prospective case series reporting a good outcome, the effectiveness and the optimal stimulation target of DBS for CCH remain unclear. We aimed to obtain precise estimates and predictors of long-term pain relief in an individual patient data meta-analysis. Furthermore, we aimed to construct a probabilistic stimulation map of effective DBS.
Hyperpolarized magnetic resonance shows that the anti-ischemic drug meldonium leads to increased flux through pyruvate dehydrogenase in vivo resulting in improved post-ischemic function in the diabetic heart.
NMR in biomedicine, 2021

The diabetic heart has a decreased ability to metabolize glucose. The anti-ischemic drug meldonium may provide a route to counteract this by reducing l-carnitine levels, resulting in improved cardiac glucose utilization. Therefore, the aim of this study was to use the novel technique of hyperpolarized magnetic resonance to investigate the in vivo effects of treatment with meldonium on cardiac metabolism and function in control and diabetic rats. Thirty-six male Wistar rats were injected either with vehicle, or with streptozotocin (55 mg/kg) to induce a model of type 1 diabetes. Daily treatment with either saline or meldonium (100 mg/kg/day) was undertaken for three weeks. in vivo cardiac function and metabolism were assessed with CINE MRI and hyperpolarized magnetic resonance respectively. Isolated perfused hearts were challenged with low-flow ischemia/reperfusion to assess the impact of meldonium on post-ischemic recovery. Meldonium had no significant effect on blood glucose concentrations or on baseline cardiac function. However, hyperpolarized magnetic resonance revealed that meldonium treatment elevated pyruvate dehydrogenase flux by 3.1-fold and 1.2-fold in diabetic and control animals, respectively, suggesting an increase in cardiac glucose oxidation. Hyperpolarized magnetic resonance further demonstrated that meldonium reduced the normalized acetylcarnitine signal by 2.1-fold in both diabetic and control animals. The increase in pyruvate dehydrogenase flux in vivo was accompanied by an improvement in post-ischemic function ex vivo, as meldonium elevated the rate pressure product by 1.3-fold and 1.5-fold in the control and diabetic animals, respectively. In conclusion, meldonium improves in vivo pyruvate dehydrogenase flux in the diabetic heart, contributing to improved cardiac recovery after ischemia.
Psychodermatological mechanisms of psoriasis.
Dermatologic therapy, 2020

Psoriasis is a chronic disease, mediated by the human immune system, based on a polygenic vulnerability, with cutaneous and systemic manifestations and substantial negative effects on the quality of life of patients. The physical and psychological impacts of psoriasis affect all areas of patient's functioning. Likewise, the prevalence of depression and anxiety in patients with psoriasis is significantly higher than that in the general population, and the quality of life is lower when compared to patients with different dermatological conditions. Both anxiety and depression may increase the clinical severity of psoriasis. Although psychiatric disorders in patients with psoriasis may be secondary to the stress due to the shame and social anxiety related to the skin lesions, the high rate of comorbidity has led to hypothesize that there may be common pathophysiological (psychodermatological) mechanisms involved. Inflammation is a key factor, since alterations in inflammatory modulators such as the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system have been described. This narrative review of the literature highlights the psychodermatological aspects of the etiopathogenesis of psoriasis as well as the impact of illness on patients' personal identity, functioning, and professional, social, and family areas.
Enlarged hippocampal fissure in psychosis of epilepsy.
Epilepsy & behavior : E&B, 2020

Psychosis of epilepsy (POE) can be a devastating condition, and its neurobiological basis remains unclear. In a previous study, we identified reduced posterior hippocampal volumes in patients with POE. The hippocampus can be further subdivided into anatomically and functionally distinct subfields that, along with the hippocampal fissure, have been shown to be selectively affected in other psychotic disorders and are not captured by gross measures of hippocampal volume. Therefore, in this study, we compared the volume of selected hippocampal subfields and the hippocampal fissure in 31 patients with POE with 31 patients with epilepsy without psychosis. Cortical reconstruction, volumetric segmentation, and calculation of hippocampal subfields and the hippocampal fissure were performed using FreeSurfer. The group with POE had larger hippocampal fissures bilaterally compared with controls with epilepsy, which was significant on the right. There were no significant differences in the volumes of the hippocampal subfields between the two groups. Our findings suggest abnormal development of the hippocampus in POE. They support and expand the neurodevelopmental model of psychosis, which holds that early life stressors lead to abnormal neurodevelopmental processes, which underpin the onset of psychosis in later life. In line with this model, the findings of the present study suggest that enlarged hippocampal fissures may be a biomarker of abnormal neurodevelopment and risk for psychosis in patients with epilepsy.

Brain Reserve in a Case of Cognitive Resilience to Severe Leukoaraiosis.
Journal of the International Neuropsychological Society : JINS, 2021

Leukoaraiosis, or white matter rarefaction, is a common imaging finding in aging and is presumed to reflect vascular disease. When severe in presentation, potential congenital or acquired etiologies are investigated, prompting referral for neuropsychological evaluation in addition to neuroimaging. T2-weighted imaging is the most common magnetic resonance imaging (MRI) approach to identifying white matter disease. However, more advanced diffusion MRI techniques may provide additional insight into mechanisms that influence the abnormal T2 signal, especially when clinical presentations are discrepant with imaging findings.
[Tissue-engineered models of the nervous system].
Medecine sciences : M/S, 2009

The nervous system is extraordinarily complex and exposed to various trauma and degenerative diseases that remain difficult to treat. To facilitate its study, in vitro models were developed by culturing neurons and glial cells in monolayer cultures, or through organotypic cultures of brain or spinal cord slices. These in vitro models were, and are still very helpful for the advancement of neurosciences. However, they are for some studies, either overly simplified, or too complex. The application of tissue engineering to neurosciences offers a new and highly versatile approach to develop accurate models of the nervous system. These models can be engineered in three-dimensions while choosing for each individual component, cellular and molecular, that will compose it. The level of complexity of the model can be adjusted from the simplest to the more complete as needed. For example, through the use of a three-dimensional tissue-engineered model of the spinal cord, it was possible to reproduce the process of myelin sheath formation around motor neuron axons for the first time in vitro. This breakthrough shows the promising potential of tissue engineering in the development of powerful in vitro models of the nervous system. The combination of these models with the use of human adult neurons and glial cells obtained from the differentiation of neural precursor cells isolated from accessible tissues from patients (skin, fat, bone marrow), opens promising perspectives to better understand -neurodegenerative diseases.
