Short-term dexamethasone plus acetylsalicylic acid treatment during in vitro fertilization procedure

Objectives: Embryo implantation represents the major limiting step during in vitro fertilization (IVF) procedure. Immu- nological and coagulation abnormalities were shown to have a substantial part in multifactorial etiology of IVF failure. We aimed to investigate the effect of short-term low-dose dexamethasone plus acetylsalicylic acid (ASA) treatment, starting at the time of embryo transfer, on the implantation and clinical pregnancy rates in general IVF population.  Material and methods: Out of 233 consecutive patients undergoing fresh IVF/intracytoplasmic sperm injection (ICSI) cycles 64 received an adjuvant treatment consisting of dexamethasone (0.5 mg/day) plus ASA (100 mg/day) (DA group), starting on the day of embryo transfer. Patients not receiving these medications comprised a control group.  Results: Significantly more patients in DA group had positive ß-hCG values than controls (59.38% vs. 37.67%, p = 0.004) (OR = 2.42, 95% CI: 1.33–4.41). Implantation rate was 26.53% in DA group and 15.92% in controls (p = 0.0294). Clinical preg- nancy rate per started cycle was higher in DA group (43.59%) than controls (28.92%), but the difference was not significant (p = 0.0879; OR = 1.99, 95% CI: 0.89–4.41).  Conclusions: Our study shows a potential benefit of dexamethasone plus ASA adjuvant treatment in females undergoing IVF/ICSI procedure. As these results show improvement of IVF outcome, a greater number of patients undergoing this type and regime of adjuvant treatment should be investigated.

Dirofilariosis and Leishmaniasis in the Northern Region of Serbia

Research in the field of vector borne diseases and zoonozes became a topic of interest in Serbia, during the last decade. Climate changes as well as higher frequency of human and animal movement and travel, especially of dogs, is rising a threat of dirofilariosis and leismaniasis. The presence of native mosquito and sandfly vectors has already been confirmed in the country and some invasive/previously not detected were found. Dirofilariosis and leishmaniasis, which are found more or less often in dogs, cause clinical symptoms which are not obvious and therefore they represent a danger for public health with dogs acting as reservoirs of the infection

The Design of a Customised Portable BCI Headset for Home Based Neurorehabilitation

This project aims to design a new portable BrainComputer Interface (BCI) headset that can be used by non-professionals (patients, caregivers) as part of BCI therapeuticapplications in the home environment.

Te signifcance of sTREM-1 as a diagnostic biomarker of sepsis in the context of Sepsis-3 definition

Aim. Sepsis remains the leading cause of mortality in spite of advanced diagnostics. Te aim of the study was to test the diagnostic value of soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) in the context of a new defnition of sepsis. Methods. Te study was conducted on 41 patients who were suspected of having sepsis according to SIRS (Systemic Infammatory Response Syndrome) criteria or sterile SIRS. 20 healthy volunteer blood donors were the control group (adult patients of both sexes). According to the latest sepsis criteria (Sepsis-3), patients were retrospectively divided into three subgroups: septic patients, patients with SIRS plus infection and patients with sterile SIRS (non-infectious SIRS). All subjects had concentrations of sTREM-1 determined by the ELISA method (Abcam commercial test, Cambridge, MA, USA). Samples were collected upon admission to hospital and kept at -20°C until laboratory analysis was performed. Results. Concentrations of sTREM-1 were signifcantly increased in patients, compared to the healthy population (p=0.021), but there were no signifcant diferences among subgroups of patients (SIRS plus infection vs. sepsis p=0.871, SIRS plus infection vs. sterile SIRS p=0.72, sepsis vs. sterile SIRS p=0.65). Te value of 300pg/mL was determined to be the optimal cut-of. Concentrations of sTREM-1 were signifcantly higher in septic patients who did not develop Multiple Organ Dysfunction Syndrome (MODS) within the frst 48 hours afer admission than in those who did. Conclusion. According to our results, sTREM-1 failed to express signifcance as a diagnostic biomarker of sepsis, according to the new defnition. Also, it seems not to be a valuable marker in diferentiation of sepsis and non-infective SIRS

On the Way Home: a BCI-FES hand therapy self-managed by sub-acute SCI participants and their caregivers: a usability study

Background: Regaining hand function is the top priority for people with tetraplegia, however access to specialised therapy outwith clinics is limited. Here we present a system for hand therapy based on brain-computer interface (BCI) which uses a consumer grade electroencephalography (EEG) device combined with functional electrical stimulation (FES), and evaluate its usability among occupational therapists (OTs) and people with spinal cord injury (SCI) and their family members. Methods: Users: Eight people with sub-acute SCI (6 M, 2F, age 55.4 ± 15.6) and their caregivers (3 M, 5F, age 45.3 ± 14.3); four OTs (4F, age 42.3 ± 9.8). User Activity: Researchers trained OTs; OTs subsequently taught caregivers to set up the system for the people with SCI to perform hand therapy. Hand therapy consisted of attempted movement (AM) of one hand to lower the power of EEG sensory-motor rhythm in the 8-12 Hz band and thereby activate FES which induced wrist flexion and extension. Technology: Consumer grade wearable EEG, multichannel FES, custom made BCI application. Location: Research space within hospital. Evaluation: donning times, BCI accuracy, BCI and FES parameter repeatability, questionnaires, focus groups and interviews. Results: Effectiveness: The BCI accuracy was 70–90%. Efficiency: Median donning times decreased from 40.5 min for initial session to 27 min during last training session (N = 7), dropping to 14 min on the last self-managed session (N = 3). BCI and FES parameters were stable from session to session. Satisfaction: Mean satisfaction with the system among SCI users and caregivers was 3.68 ± 0.81 (max 5) as measured by QUEST questionnaire. Main facilitators for implementing BCI-FES technology were “seeing hand moving”, “doing something useful for the loved ones”, good level of computer literacy (people with SCI and caregivers), “active engagement in therapy” (OT), while main barriers were technical complexity of setup (all groups) and “lack of clinical evidence” (OT). Conclusion: BCI-FES has potential to be used as at home hand therapy by people with SCI or stroke, provided it is easy to use and support is provided. Transfer of knowledge of operating BCI is possible from researchers to therapists to users and caregivers

Effect of Neuromuscular Training Program on Quality of Life After COVID-19 Lockdown Among Young Healthy Participants: A Randomized Controlled Trial

Study in the period of coronavirus disease 2019 (COVID-19) lockdown and the effect of different exercise training programs on the quality of life (QoL) dimension are limited. This randomized control study as a part of which the impact of an 8-week neuromuscular training program on the 90 healthy young individuals’ QoL after COVID-19 lockdown was assessed using a short form of the WHOQOL-BREF questionnaire comprising of four domains (physical health, psychological health, social relations, and the environment). The intervention group (NT) (n = 47) took part in a neuromuscular training program consisting of dynamic neuromuscular stabilization and whole-body vibration training. In contrast, the control group (CG) (n = 43) did not participate in any programmed physical activity. From pre- to post-intervention test, the NT group significantly and substantially improved [mean change (95% CI)] all the QoL domains, physical for 12.78 scores (8.89, 16.64), psychological for 13.12 scores (9.51, 16.74), social relationships for 20.57 scores (16.12, 25.02), and environmental for 24.40 scores (21.45, 27.35). These results suggest that the NT program could enhance QoL in young and healthy participants following COVID-19 lockdown

Identification of novel genetic risk factors of dilated cardiomyopathy: from canine to human

BackgroundDilated cardiomyopathy (DCM) is a life-threatening heart disease and a common cause of heart failure due to systolic dysfunction and subsequent left or biventricular dilatation. A significant number of cases have a genetic etiology; however, as a complex disease, the exact genetic risk factors are largely unknown, and many patients remain without a molecular diagnosis.MethodsWe performed GWAS followed by whole-genome, transcriptome, and immunohistochemical analyses in a spontaneously occurring canine model of DCM. Canine gene discovery was followed up in three human DCM cohorts.ResultsOur results revealed two independent additive loci associated with the typical DCM phenotype comprising left ventricular systolic dysfunction and dilatation. We highlight two novel candidate genes, RNF207 and PRKAA2, known for their involvement in cardiac action potentials, energy homeostasis, and morphology. We further illustrate the distinct genetic etiologies underlying the typical DCM phenotype and ventricular premature contractions. Finally, we followed up on the canine discoveries in human DCM patients and discovered candidate variants in our two novel genes.ConclusionsCollectively, our study yields insight into the molecular pathophysiology of DCM and provides a large animal model for preclinical studies

Hematological and biochemical markers in determining the diagnosis and stage prediction of endometrial cancer

Objectives: To establish whether there is a statistically significant difference in hematological and biochemical parameters between the patients with premalignant changes of the uterine mucosa and those with malignant changes. The aim is to establish whether hematological and biochemical parameters may be useful in predicting the stages of endometrial malignancy and in differentiating premalignant and malignant endometrial changes. Material and methods: A retrospective study included 100 patients (70 with endometrial carcinoma diagnosis and 30 with atypical hyperplasia). We compared hematological and biochemical parameters in both groups. Results: CRP, granulocytes, platelets, neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR) are statistically significantly higher in patients with malignant changes. Lymphocyte count is statistically significantly lower in patients with malignant changes. Platelet count is statistically significantly lower in patients with stages I and II in comparison to patients with higher disease stage. NLR and PLR have good discriminatory power for carcinoma presence. Patients with advanced changes have statistically significantly higher CRP values, higher granulocyte and platelet count, as well as higher values of NLR and PLR, and statistically significantly lower values of lymphocytes and MPV in comparison to benign changes. Conclusions: There is a possibility of using hematological and biochemical parameters in the assessment of endometrial changes as well as in the prediction of stages, in confirmed malignant changes of the endometrium
