Healthcare Workers' Vulnerability to SARS-CoV-2 in Western Romania: A Study on Incidence and Risk Factors for Non-Vaccination and Reinfection.

Purpose: The COVID-19 pandemic has severely impacted healthcare workers, a professional category at risk of infection in both hospital and community settings. The aim of the study was to compare morbidity among hospital staff and that in general population, as well as the factors predicting non-vaccination and reinfection. Patients and Methods: The present study is a retrospective, cross-sectional study. It was conducted by including all the confirmed COVID-19 infection cases in medical staff members during the period 01.01.2021-31.03.2022 that were reported to the Public Health Authority of Timis County, Timisoara, Western Romania. Results: Direct, strong, statistically significant correlations were found between the incidence of COVID-19 recorded in all categories of medical personnel and the community pandemic trend, with maximum values for auxiliary and medium medical staff (rho = 0.852/0.821, p < 0.001). The high socio-economic level, as well as the advanced medical education level, were predictor factors for anti-SARS-COV-2 vaccination among the personnel. The non-vaccinated status as well as incomplete vaccination or even the 2-dose vaccination represented independent risk factors for reinfection in 2022. Conversely, receiving a higher number of vaccine doses emerged as the primary protective factor. Notably, reduced adherence to the administration of the following doses was observed particularly among medium and auxiliary staff, leading to additional risks of infection with the Omicron variant. Conclusion: Despite over 70% vaccination coverage among all studied medical personnel categories, there was low adherence to repeat doses of vaccination, particularly among medium and auxiliary staff. The study highlighted a distinct necessity for enhanced training on preventive behaviours and targeted prevention/control strategies for all professional groups interacting with patients, including caretakers, ambulance workers, receptionists, physiotherapists, and psychologists.

Staged Treatment of Posttraumatic Tibial Osteomyelitis with Rib Graft and Serratus Anterior Muscle Autografts-Case Report.

Osteomyelitis of the tibia is a challenging condition, particularly when it occurs as a result of trauma. This abstract presents a case study detailing the successful staged treatment of posttraumatic tibial osteomyelitis utilizing a unique combination of rib graft and serratus anterior muscle. This medical abstract presents a case study of a 52-year-old male with a history of heavy smoking and obliterating arteriopathy of the lower limbs. The patient sustained a traumatic open fracture classified as Type IIIA Gustilo Anderson involving one-third of the distal right tibia diaphysis, with an associated right fibular malleolus fracture. The treatment approach comprised multiple stages, focusing on wound management, infection control, and limb salvage. The initial stage involved the application of an external fixation device in the emergency setting. Seven days later, an osteosynthesis procedure was performed using a Kuntscher nail and wire cerclage. However, complications emerged, with wound dehiscence and purulent secretion observed at 14 days postsurgery. Subsequently, secondary suturing was carried out at the 20-day mark. The second stage of the treatment involved implant removal, wide excisional debridement, pulse lavage, osteoclasia, and relaxation of the peroneal malleolus. A monoplane external fixation system was applied. As a part of postoperative care, aspiration therapy with a vacuum pump was administered, along with a 10-day course of vancomycin according to the antibiogram. Positive clinical signs of healing were noted, and sterile cultures confirmed the results. The third stage of the intervention focused on grafting the osteo-muscular defect, utilizing autografts from the rib and serratus anterior muscle. The external fixator was maintained in place during this phase. In the fourth and final stage, after an 8-week integration period of the musculocutaneous flap, the external fixator was removed, and internal fixation was accomplished with a blocked Less Invasive Stabilization System (LISS) plate inserted using the Minimally Invasive Plate Osteosynthesis (MIPO) technique. This case underscores the significance of a multistage approach in managing complex limb injuries, emphasizing the importance of timely intervention, infection control, and innovative techniques for limb salvage and restoration of function.

Robotic Process Automation Based Data Extraction from Handwritten Medical Forms.

This paper proposes to create an RPA(robotic process automation) based software robot that can digitalize and extract data from handwritten medical forms. The RPA robot uses a taxonomy that is specific for the medical form and associates the extracted data with the taxonomy. This is accomplished using UiPath studio to create the robot, Google Cloud Vision OCR(optical character recognition) to create the DOM (digital object model) file and UiPath machine learning (ML) API to extract the data from the medical form. Due to the fact that the medical form is in a non-standard format a data extraction template had to be applied. After the extraction process the data can be saved into databases or into a spreadsheets.

Patterned Sensory Enhancement, a Music Rehabilitation Therapy for Elderly Patients with Neuromotor Deficit during the COVID-19 Pandemic: A Pilot Study.

(1) Background: The Patterned Sensory Enhancement (PSE) technique refers to a music-based rehabilitation therapy strategy used in neurological pathologies. (2) Methods: This study aims at developing a music-drill protocol for recovery in elderly patients with neuromuscular degenerative pathologies. Each music drill is based on a number of specific music-composition parameters. The conclusions represent suggestions for further enhancing the PSE technique through collaborations between the rehabilitation team and the musicians involved due to the importance of the music stimuli used as a therapy. (3) Results: The music-composition parameters used in this study relate to the existence of music homogeneity factors such as the key signature and rhythm; the importance of the major scale and the tonal system in general; the obvious music suggestions of movement, repetition or absence of movement; the importance of rhythm; the introduction of musical instruments in order to harmonize the music material as much as possible; the connection between PSE music along with patients' musical taste and the musical recording as a therapy during patient outcare; (4) Conclusions: The therapy efficiency was observed by measurements taken before and after the therapeutic intervention by means of a Takei dynamometer. The present study asserts that for a patient undergoing the PSE technique, the researcher should compose personalized music material adapted to each patient's peculiarities.

Impact of General Anesthesia Guided by State Entropy (SE) and Response Entropy (RE) on Perioperative Stability in Elective Laparoscopic Cholecystectomy Patients-A Prospective Observational Randomized Monocentric Study.

Laparoscopic cholecystectomy is one of the most frequently performed interventions in general surgery departments. Some of the most important aims in achieving perioperative stability in these patients is diminishing the impact of general anesthesia on the hemodynamic stability and the optimization of anesthetic drug doses based on the individual clinical profile of each patient. The objective of this study is the evaluation of the impact, as monitored through entropy (both state entropy (SE) and response entropy (RE)), that the depth of anesthesia has on the hemodynamic stability, as well as the doses of volatile anesthetic. A prospective, observational, randomized, and monocentric study was carried out between January and December 2019 in the Clinic of Anesthesia and Intensive Care of the "Pius Brînzeu" Emergency County Hospital in Timișoara, Romania. The patients included in the study were divided in two study groups: patients in Group A (target group) received multimodal monitoring, which included monitoring of standard parameters and of entropy (SE and RE); while the patients in Group B (control group) only received standard monitoring. The anesthetic dose in group A was optimized to achieve a target entropy of 40-60. A total of 68 patients met the inclusion criteria and were allocated to one of the two study groups: group A (N = 43) or group B (N = 25). There were no statistically significant differences identified between the two groups for both demographical and clinical characteristics (p > 0.05). Statistically significant differences were identified for the number of hypotensive episodes (p = 0.011, 95% CI: [0.1851, 0.7042]) and for the number of episodes of bradycardia (p < 0.0001, 95% CI: [0.3296, 0.7923]). Moreover, there was a significant difference in the Sevoflurane consumption between the two study groups (p = 0.0498, 95% CI: [-0.3942, 0.9047]). The implementation of the multimodal monitoring protocol, including the standard parameters and the measurement of entropy for determining the depth of anesthesia (SE and RE) led to a considerable improvement in perioperative hemodynamic stability. Furthermore, optimizing the doses of anesthetic drugs based on the individual clinical profile of each patient led to a considerable decrease in drug consumption, as well as to a lower incidence of hemodynamic side-effects.

Intravenous iron infusion as an alternative to minimize blood transfusion in peri-operative patients.

Despite the reported benefits of intravenous iron therapy (IVIT) for correcting iron deficiency anemia (IDA) before any major surgery and the evidence thereof, perioperative allogenic blood transfusion (ABT) practice is still considered as the only viable option by some clinicians worldwide. As ABT increases the likelihood of infections, cardiac complications, longer hospital stays and mortality among the patients, the practice of ABT should only be reserved for critical cases (Hb level < 7 g/dl). Timely iron studies and iron replenishment (oral/IV) of prospective surgical patients could help decrease the ABT practice, and prove beneficial from both the clinical and economic standpoint. Evidence based patient blood management guidelines should be developed and standardized for use by clinicians worldwide. These guidelines should include specific instructions on timely assessment of surgical patients for correction of their IDA by either oral iron supplementation, if time permits, or by using IVIT such as ferric carboxymaltose (FCM) in emergency surgeries and in patients with functional ID. This study was conducted to explore the clinical benefits of the timely administration of IV-FCM in iron-deficient preoperative patients during 2017-2018 and compare the results thereof with that of the ABT. Based on the IDA treatment plan of 2953 patients, 11.14% cases were administered IV FCM (Group 1), 11.58% cases received ABT (Group 2), while the remaining 77.27% of anemic cases received neither ABT nor IV FCM (Group 3). The results indicate that the IV FCM administration reduces the need for ABT and thus minimizes its associated side effects. The findings of our study concur with the favorable outcomes reported by the other similar studies.

Cannabis Sativa Revisited-Crosstalk between microRNA Expression, Inflammation, Oxidative Stress, and Endocannabinoid Response System in Critically Ill Patients with Sepsis.

Critically ill patients with sepsis require a multidisciplinary approach, as this situation implies multiorgan distress, with most of the bodily biochemical and cellular systems being affected by the condition. Moreover, sepsis is characterized by a multitude of biochemical interactions and by dynamic changes of the immune system. At the moment, there is a gap in our understanding of the cellular, genetic, and molecular mechanisms involved in sepsis. One of the systems intensely studied in recent years is the endocannabinoid signaling pathway, as light was shed over a series of important interactions of cannabinoid receptors with biochemical pathways, specifically for sepsis. Furthermore, a series of important implications on inflammation and the immune system that are induced by the activity of cannabinoid receptors stimulated by the delta-9-tetrahydrocannabinol (Δ9-THC) and cannabidiol (CBD) have been noticed. One of the most important is their ability to reduce the biosynthesis of pro-inflammatory mediators and the modulation of immune mechanisms. Different studies have reported that cannabinoids can reduce oxidative stress at mitochondrial and cellular levels. The aim of this review paper was to present, in detail, the important mechanisms modulated by the endocannabinoid signaling pathway, as well as of the molecular and cellular links it has with sepsis. At the same time, we wish to present the possible implications of cannabinoids in the most important biological pathways involved in sepsis, such as inflammation, redox activity, immune system, and epigenetic expression.

New Molecular and Epigenetic Expressions as Novel Biomarkers in Critically Ill Polytrauma Patients with Acute Kidney Injury (AKI).

BACKGROUND: A high percentage of the critically ill polytrauma patients develop acute kidney injury (AKI) secondary to trauma and are therefore prone to high morbidity and mortality rates. One of the main objectives in these cases is the fast detection of the condition and continuous rigorous monitoring of the patients. Currently the panel of biomarkers available for monitoring and for the prognosis of AKI is limited. Numerous studies have proven the importance of microRNAs in this field. In this actualization paper we wish to summarize the most relevant microRNAs that can be used as biomarkers for patients with AKI. METHODS: For this paper, we looked into the studies available in scientific databases such as PubMed and Scopus. For the analysis we used the following key words: "miRNAs biomarker", "acute kidney injury AKI", "genetic expression in AKI", and "epigenetic microRNAs biomarkers in AKI". RESULTS: Numerous studies have shown high specificity for certain microRNA species in the case of patients with AKI. Moreover, they have reported a series of microRNAs that present high specificity and that have a strong expression in fluids that can be sampled through non-invasive methods, such as urine and saliva. CONCLUSIONS: The expression of microRNAs can be successfully used in the future as a non-invasive method for the evaluation and monitoring of AKI patients.

Analysis of oxidative stress-related markers in critically ill polytrauma patients: An observational prospective single-center study.

Critically ill polytrauma patients have increased production of free radicals (FRs) and consequent alterations in biochemical pathways, as well as disruption of cellular integrity, due to increased lipid peroxidation. The aim of this study was to investigate several biomarkers associated with increased oxidative stress in critically ill polytrauma patients, and to evaluate the effect of antioxidant treatment on the clinical outcome in these patients. A total of 67 polytrauma patients from an intensive care unit met the selection criteria. Antiox group included 35/67 patients who received antioxidant therapy, while 32/67 patients without antioxidant treatment were considered as control group. Antioxidant therapy consisted of simultaneous administration of Vitamin C (sodium ascorbate) and N-acetylcysteine, through continuous intravenous infusion. Clinical and paraclinical evaluation of the patients was performed daily until discharge or death. At admission, laboratory parameters did not differ significantly between two groups. At discharge/upon death, statistically significant differences in favor of Antiox group were observed in the following parameters: thrombocytes, activated partial thromboplastin time, prothrombin time, total bilirubin, total cholesterol, high-density lipoproteins, low-density lipoproteins, erythrocyte sedimentation rate, interleukin 6 (all p = 0.0001), total protein (p = 0.0005), serum albumin (p = 0.0004), lactate dehydrogenase (p = 0.0006), and C-reactive protein (p = 0.0014). Starting from day 5, the APACHE II score was significantly decreased in Antiox versus control group (p < 0.05). Finally, the sepsis incidence and mortality rate were significantly lower in Antiox group (p < 0.05). Decreasing the level of oxidative stress by antioxidant substances significantly correlated with a better prognosis and outcome in our patients. Further studies should elucidate more clearly the mechanism of action of antioxidants in critically ill polytrauma patients.

Circulating microRNAs Expressions as Genetic Biomarkers in Pancreatic Cancer Patients Continuous Non-Invasive Monitoring.

BACKGROUND: Pancreatic cancer is one of the most important causes of death worldwide. The main cause is late detection. Also, an important factor playing a role in altering the clinical status of these patients is the lack of methods for the evaluation of therapeutic response. A marker that can be useful, both in early diagnosis and in evaluating and monitoring non-invasive treatment response, is analyzing the expression of miRNAs. In this paper, we summarize genetic and epigenetic aspects of miRNAs in pancreatic cancer. Moreover, we want to emphasize potential miRNAs expressions that can be used as biomarkers for the management of patients with pancreatic cancer. METHODS: Studies available in scientific databases, such as PubMed and Scopus, were analyzed for conducting the present study. The keywords "miRNAs expression", "pancreatic cancer", and "genetic biomarkers" were used in the search engine. RESULTS: Following the searches, 187 primary scientific articles were analyzed. After rigorous analysis 40 articles were selected for the study. A high percentage of papers highlight the importance of using microRNAs as modern, non-invasive, and accurate biomarkers, designed for the early diagnosis and continuous monitoring of both the clinical outcome and treatment response of the patient. CONCLUSIONS: The expression of miRNAs can be successfully used for the evaluation and non-invasive monitoring of patients with pancreatic cancer.
