Abstract
Background
Patients with cerebellar malformations exhibit not only movement problems, but also important deficits in social cognition. Thus, rehabilitation approaches should not only involve the recovery of motor function but also of higher-order abilities such as processing of social stimuli. In keeping with the general role of the cerebellum in anticipating and predicting events, we used a VR-based rehabilitation system to implement a social cognition intensive training specifically tailored to improve predictive abilities in social scenarios (VR-Spirit).

Methods/design
The study is an interventional randomised controlled trial that aims to recruit 42 children, adolescents and young adults with congenital cerebellar malformations, randomly allocated to the experimental group or the active control group. The experimental group is administered the VR-Spirit, requiring the participants to compete with different avatars in the reaching of recreational equipment and implicitly prompting them to form expectations about their playing preference. The active control group participates in a VR-training with standard games currently adopted for motor rehabilitation. Both trainings are composed by eight 45-min sessions and are administered in the GRAIL VR laboratory (Motekforce Link, Netherlands), an integrated platform that allows patients to move in natural and attractive VR environments. An evaluation session in VR with the same paradigm used in the VR-Spirit but implemented in a different scenario is administered at the beginning (T0) of the two trainings (T1) and at the end (T2). Moreover, a battery of neurocognitive tests spanning different domains is administered to all participants at T0, T2 and in a follow-up session after 2 months from the end of the two trainings (T3).

Discussion
This study offers a novel approach for rehabilitation based on specific neural mechanisms of the cerebellum. We aim to investigate the feasibility and efficacy of a new, intensive, social cognition training in a sample of Italian patients aged 7–25 years with congenital cerebellar malformations. We expect that VR-Spirit could enhance social prediction ability and indirectly improve cognitive performance in diverse domains. Moreover, through the comparison with a VR-active control training we aim to verify the specificity of VR-Spirit in improving social perception skills.

Published: January 2020

Abstract
Background
High-flow nasal cannula (HFNC) oxygen therapy has been widely used in critically ill patients. Despite the effectiveness of HFNC as a treatment, optimal methods to withdraw HFNC after recovery from preexisting conditions have not been investigated to date. In this study, we will evaluate the safety and efficacy of simultaneous reduction of flow and fraction of inspired oxygen (FiO2) compared with sequential reduction of either flow first or FiO2 reduction first in patients with HFNC.

Methods/design
This is a prospective, investigator-initiated, randomized controlled trial with three experimental intervention groups. A total of 100 adult patients receiving HFNC and satisfying weaning criteria will be enrolled and randomly assigned to one of the following groups: flow reduction (FR) first, FiO2 reduction (OR) first, or simultaneous reduction (SR). In the FR group, flow will be reduced first by 10 L/min/h. When it reaches 20 L/min, FiO2 will then be reduced by 0.1 /h until it reaches 0.3. In the OR group, the FiO2 will be gradually reduced first by 0.1 /h until it reaches 0.3, then flow will be reduced by 10 L/min until it reaches 20 L/min. Finally, in the SR group, both the flow and FiO2 will be gradually reduced simultaneously by 10 L/min and 0.1/h, respectively. Weaning will proceed only when patients satisfy the weaning criteria at every weaning point. When the HFNC weaning-off targets are reached (20 L/min and 0.3 for flow and FiO2, respectively), the patient will be transferred to conventional oxygen therapy (mainly low-flow nasal prongs). The primary outcome is the time to successful weaning from HFNC for 24 h. Secondary outcomes will include the success or failure rate in weaning off HFNC and changes in arterial blood gas analyses, intolerance rate, length of hospital stay, and in-hospital mortality.

Discussion
This study will be the first clinical trial to investigate the safety and efficacy of three different methods of weaning in adult patients receiving HFNC. Once this study is completed, we expect to be able to suggest the better strategy for withdrawal of HFNC based on the results.

Abstract
Background
Blastocystis sp. affects a wide variety of animals and is the most common protozoan in human fecal samples with potential pandemic distribution. In the present study, a systematic review and meta-analysis were conducted to determine the prevalence and distribution of Blastocystis sp. in different classes of hosts in Brazil.

Methods
Studies that analyzed hosts of various classes, including humans, domestic animals, wild animals or captive animals, were considered. The pooled prevalence of Blastocystis sp. infection was estimated by random effects models.

Results
For humans, similar prevalence rates were found for males (31.0%, 95% CI: 17.0–45.0%; weight 10%) and females (28.0%, 95% CI: 16.0–41.0%; weight 10%); the state of Mato Grosso do Sul showed the highest prevalence, with 41.0% positivity (95% CI: 36.0–46.0%; weight 2.9%). The prevalence among immunocompromised patients was 5.0% (95% CI: 3.0–7.0%; weight 10%), and the most common cause of immunosuppression was hemodialysis, with 23.0% (95% CI: 17.0–29.0%; weight 12.4%). Among classifications according to interaction with humans, wild and domestic animals presented values of 19.0% (95% CI: 7.0–31.0%; weight 42.6%) and 17.0% (95% CI: 13.0–21.0%; weight 29.6%), respectively. Among these animals, mammals (39.0%, 95% CI: 21.0–56.0%; weight 47.3%) and birds (18.0%, 95% CI: 10.0–27.0%; weight 39.3%) exhibited the highest prevalence. Phylogenetic analysis of Blastocystis sp. revealed greater genetic diversity for clades of subtypes (STs) ST1, ST2 and ST3.

Conclusions
The overall prevalence of Blastocystis sp. in the Brazilian human population was 24%, which reflects the reality in the South, Southeast and Midwest regions, where prevalence rates of up to 40% were found. Among animals, mammals and birds exhibited the highest prevalence.
Molecular profiling for precision cancer therapies

Published: January 2020

AbstractThe number of druggable tumor-specific molecular aberrations has grown substantially in the past decade, with a significant survival benefit obtained from biomarker matching therapies in several cancer types. Molecular pathology has therefore become fundamental not only to inform on tumor diagnosis and prognosis but also to drive therapeutic decisions in daily practice. The introduction of next-generation sequencing technologies and the rising number of large-scale tumor molecular profiling programs across institutions worldwide have revolutionized the field of precision oncology. As comprehensive genomic analyses become increasingly available in both clinical and research settings, healthcare professionals are faced with the complex tasks of result interpretation and translation. This review summarizes the current and upcoming approaches to implement precision cancer medicine, highlighting the challenges and potential solutions to facilitate the interpretation and to maximize the clinical utility of molecular profiling results. We describe novel molecular characterization strategies beyond tumor DNA sequencing, such as transcriptomics, immunophenotyping, epigenetic profiling, and single-cell analyses. We also review current and potential applications of liquid biopsies to evaluate blood-based biomarkers, such as circulating tumor cells and circulating nucleic acids. Last, lessons learned from the existing limitations of genotype-derived therapies provide insights into ways to expand precision medicine beyond genomics.
Combatting joint pain and inflammation by dual inhibition of monoacylglycerol lipase and cyclooxygenase-2 in a rat model of osteoarthritis
Authors: Philpott Holly T. , McDougall Jason J. 
Published: January 2020

Abstract
Background
Endocannabinoids are showing great promise as effective mediators for controlling joint inflammation and pain. One strategy that could be harnessed to promote endogenous cannabinoid function is to inhibit the enzymatic break down of endocannabinoids locally in the joint. KML29 is an inhibitor of monoacylglycerol lipase (MAGL) activity which has been shown to promote increased 2-arachodonylglycerol (2-AG) levels in the circulation and in peripheral tissues. It is also known that 2-AG can be metabolised via the cyclo-oxygenase-2 (COX-2) pathway leading to the production of pro-inflammatory prostaglandins, which may counteract the effects of 2-AG. Therefore, this study examined the effect of KML29 alone as well as in combination with low-dose celecoxib (CXB) on joint pain and inflammation in the monoiodoacetate (MIA) model of osteoarthritis (OA) pain.

Methods
Injection of MIA (3 mg) into the knee joints of male Wistar rats was used to model OA pain, inflammation, and nerve damage. Pain behaviour was assessed by von Frey hair algesiometry, and inflammation was evaluated using intravital microscopy to measure leukocyte trafficking in the synovial microvasculature.

Results
Intra-articular injection of MIA produced mechanical hypersensitivity as measured by von Frey hair algesiometry. Local injection of KML29 (700 μg) reduced joint pain at day 14 post-MIA induction, and this analgesic effect was blocked by the cannabinoid receptor antagonists AM281 and AM630 (P < 0.0001; n = 6). During the acute inflammatory phase of the MIA model (day 1), a significant reduction in withdrawal threshold (P < 0.0001; n = 6–8) and leukocyte trafficking was seen after treatment with KML29 + CXB (P < 0.0001; n = 6–8). Early treatment of MIA-injected knees (days 1–3) with KML29 + CXB ameliorated the development of mechanical secondary allodynia (P < 0.0001; n = 8) in the later stages of the MIA model.

Conclusions
Combination therapy of KML29 plus CXB reduced joint pain and inflammation. Thus, dual inhibition of MAGL and cyclooxygenase-2 pathways could be a useful approach to alleviate joint inflammation and pain in OA joints.
Hemiarthroplasty in a patient with femoral neck fracture and pyoderma gangrenosum: a case report and review of the literature
Authors: Antoni Anna , Trautinger Franz , Heinz Thomas , Hajdu Stefan 
Published: January 2020

Abstract
Background
Pyoderma gangrenosum is a rare ulcerating skin disease of unknown etiology, making its coincidence with orthopedic trauma a rare challenge. Patients are at risk of progression of the existing lesions and development of new lesions upon skin injury when surgical procedures are performed. To our knowledge, this is the first report in the literature of disease unrelated surgery during active pyoderma gangrenosum.

Case presentation
We present a case of femoral neck fracture in a Caucasian patient with concurrent pyoderma gangrenosum localized in the axilla. Hemiarthroplasty was safely performed after disease activity was reduced with systemic corticosteroids. Tissue-protective wound closure was used together with perioperative corticosteroids and antibiotics. No signs of pyoderma gangrenosum developed at the surgical wound site, and the axillary lesions showed constant improvement until healing with scar tissue.

Conclusions
In our patient, the preoperative steroid treatment, perioperative antibiotics, and soft tissue protective surgical technique led to successful management of this rare coincidence.
Implementation of a Patient Reported Experience Measure in a Dutch disability care organisation: a qualitative study
Authors: van Rooijen Marjolein , Lenzen Stephanie , Dalemans Ruth , Moser Albine , Beurskens Anna 
Published: January 2020

Abstract
Background
Patient Reported Experience Measures are promoted to be used as an integrated measurement approach in which outcomes are used to improve individual care (micro level), organisational quality (meso level) and external justification (macro level). However, a deeper understanding of implementation issues of these measures is necessary. The narrative Patient Reported Experience Measure “Dit vind ik ervan!” (English “How I feel about it!”) is used in the Dutch disability care sector, but insight into its’ current use is lacking. We aimed to provide insight into experiences with the implementation and current ways of working with “Dit vind ik ervan!” as an integrated measurement strategy.
A descriptive qualitative study was done at a disability care organisation. Data were collected by nine documentations, seven observations, 11 interviews and three focus groups. We applied deductive content analysis using the Consolidated Framework for Implementation Research as a framework.

Results
Our analysis revealed facilitators and barriers for the implementation of “Dit vind ik ervan!”. We found most barriers at the micro level. Professionals and clients appreciated the measure’s narrative approach, but struggled to perform it with communication vulnerable clients. Some clients, professionals and team leaders were unfamiliar with the measure’s aim and benefit. On the meso level, implementation was done top-down, and the management’s vision using the measure as an integrated measurement approach was insufficiently shared throughout the organisation.

Conclusions
Our study shows that Patient Reported Experience Measures have the potential to be used as an integrated measurement strategy. Yet, we found barriers at the micro level, which might have influenced using the measurement outcomes at the meso and macro level. Tailored implementation strategies, mostly focusing on designing and preparing the implementation on the micro level, need to be developed in co-creation with all stakeholders.
The role of diagnostic hysteroscopy in diagnosis of incomplete uterine septum/significant arcuate uterine anomaly in infertile patients in the era of transvaginal 3D ultrasound scan
Authors: Abuzeid O. , LaChance J. , Zaghmout O. , Corrado J. , Hebert J. , Ashraf M. , Abuzeid M. I. 
Published: January 2020

Abstract
Background
To determine the accuracy of measurement of internal indentation length on transvaginal 3D ultrasound scan (TV 3D US) in detecting patients with an incomplete uterine septum (IUS) or a significant arcuate uterine anomaly (AUA) based on the actual length as measured on diagnostic hysteroscopy. We compared the mean internal indentation length on TV 3D US and on diagnostic hysteroscopy in patients with IUS or a significant AUA.

Results
This is a retrospective study of 546 patients who were found to have IUS (134) or significant AUA (412) on diagnostic hysteroscopy and who had TV 3D US prior to surgery. The mean internal indentation length measured in millimeter on hysteroscopy was significantly higher than the mean internal indentation length measured on TV 3D US in patients with IUS (16.7 + 5.5 vs 5.5 + 4.2; P < 0.001), in patients with significant AUA (12.9 + 2.8 vs 3.9 + 4.6; P < 0.001), and in the overall population (13.8 + 4.0 vs 4.3 + 4.5; P < 0.001). The same findings were obtained when the comparison was limited to patients who had moderate significant internal indentation length (10–14 mm) and those with significant internal indentation length (15–25 mm).

Conclusion
Data in this study suggests that the mean internal indentation length in patients with IUS or AUA can be underestimated on TV 3D US. A diagnostic hysteroscopy is the only gold standard to make the correct diagnosis in these patients.
Evaluation of the predictive value of thorax trauma severity score (TTSS) in thoracic-traumatized patients
Authors: Zahran Mohamed Reda , Elwahab Amr Abd El Monem Abd , El Nasr Mohamed Mahmoud Abo , El Heniedy Mohamed Ahmed 
Published: January 2020

Abstract
Background
Thorax trauma severity score (TTSS) combines patient-related parameters with the anatomical and physiological parameters, and it can be easily calculated in the emergency room. The validity of this score in the Egyptian population has not been tested; therefore, the objective of this study was to evaluate the prognostic role of TTSS to predict the outcome of thoracic trauma in the Egyptian patients in two centers.

Results
The study included 284 male patients (94.7%) with a mean age of 41 years. Fifty-six patients (18.7%) had conservative management, 216 had morbidity (72%), and 28 patients died (9.3%). One hundred forty-eight patients (49.3%) had a thoracostomy tube, and thoracotomy was required in 4 patients (1.3%). Respiratory rate above 20 cycles/min at admission was associated with mortality (n = 28 (9.3%); p < 0.001). One hundred thirty-six patients had TTSS between 0 and 5 points; 56 of them were discharged and 80 of them were admitted to the inpatient ward with a good prognosis. Twenty-four patients had TTSS between 21 and 25 points; all the 24 patients had a fatal prognosis. A cut-off value of 7 points or more of TTSS was 100% sensitive and 97.73% specific to poor and fatal prognosis, and it was significantly associated with acute respiratory distress syndrome and the need for mechanical ventilation (n = 64; p < 0.001; AUC = 0.998).

Conclusion
The outcome of thoracic trauma patients could be predicted based on the thorax trauma severity score. A score of 7 points or above was associated with increased morbidity, and a score of 20 points or above predicted a fatal prognosis and prolonged mechanical ventilation.
A compression device versus compression stockings in long-term therapy of lower limb primary lymphoedema after liposuction
Authors: Karafa Marian , Karafová Anna , Szuba Andrzej 
Published: January 2020

Objective: Primary lymphoedema is rare and in most cases develops in the lower extremities. In some cases, conservative treatment is insufficient and can be supported by surgical procedure. The aim of this case study was to show the difference in the effectiveness of a compression wrap device and compression stockings in the treatment of primary lymphoedema. Method: Before and after liposuction the patient was treated on an outpatient basis every day for three weeks. This consisted of complex decongestive therapy (CDT) including manual lymph drainage, tailored exercises, skin and nail care, compression therapy and intermittent pneumatic compression. After CDT, the patient was provided with a flat-knit compression garment. Measurements were taken at one week and at three months of wearing the compression garment. The oedema severity was measured by summary calculation method. For both healthy and swollen limbs, the sum of circumferences taken at nine fixed measuring points was determined. The difference between these sums expressed in percents was presented as a relative metric coefficient of leg lymphoedema (RMCL). Results: At the start of therapy, the difference in circumference between the healthy and swollen limb was 21.85%. After CDT (RMCL: 13.46%), the patient was provided with a flat-knit compression stocking (class 3). After one week, the RMCL was 15.92%, while after three months RCML was 20.84%. Because fluid retention was observed the patient was again treated with CDT (RMCL: 13.89%). The patient was provided with compression stocking (class 4). After one week of wearing, the RMCL was 15.77%, while after three months RMCL was 20.26%. As the results proved unsatisfactory, the patient was treated with CDT (RMCL: 13.60%) and a combination of two class 4 compression stockings was used. After one week, RMCL was 14.91%, while after three months RMCL was 19.25%. As the effects of oedema reduction were insufficient, the patient was treated again with CDT (RMCL: 13.89%) and advised to replace one of the stockings with a CirAid device (adjustable compression wrap). After one week, RMCL was 14.18% and after three months RMCL was 14.76%. The patient then qualified for liposuction (RMCL: 7.81%). At three months after surgery, the compression stocking was replaced by an adjustable compression wrap, to reduce the difference in circumference between healthy and swollen limbs (from 21.85 % to 8.68%). Conclusion: This case study shows that in primary oedema one class of compression garment is not always sufficient, nor is the combination of two garments with varying degrees of compression. In some cases, the situation requires the use of non-elastic leg binders such as a CircAid device which, thanks to its greater stiffness, helps improve clinical outcomes.

Published: January 2020

Objective:This study aims to compare the efficacy of enoxaparin, rivoraxaban and dabigatran on wound healing using a rat model.Method:Sprague-Dawley female rats (n=56), 10–12 weeks old, weight 245±30g, were used in this study. The rats were divided into four equally-sized groups. A type 1 (secondary wound healing) and type 2 (primary wound healing) wound was opened surgically on each rat in each group. Anticoagulent drugs enoxaparin, rivoraxaban and dabigatran and physiological saline solution were administered to Groups 1, 2, 3 and 4, respectively. After wound healing was scored tissue samples were taken from euthanised rats at days five and 10 and examined histologically. Since time was used as a classification (days five and 10), a time effect was included.Results:There was no statistically significant difference in total score distribution in rats between type 1 secondary wounds for days five and 10 (p>0.05). There was no statistically significant difference in the overall score distribution in rats between type 2 primary wounds for days five and 10 (p>0.05).Conclusion:In addition to the use of low molecular weight heparin with well-known anticoagulation activity, the new generation oral medications are used efficiently in thromboembolic diseases. However, there was no evidence observed in this study that these drugs could be either beneficial or harmful to wound healing.
