Challenges and Complications in Treating Total Knee Arthroplasty in Morbidly Obese Patients.

The number of total hip and total knee replacements has increased steadily each year. Today, they are routinely performed all over the world. The increasing prevalence of obesity has led to an increase in the number of total knee arthroplasties (TKAs) performed in patients with a higher body mass index (BMI) and also has a higher rate of complications. Possible complications are infection, instability, misalignment, osteolysis, or fracture. Revision arthroplasty can be challenging due to bone defects, ligament instability, and difficulty in fixation. We present the case of a 66-year-old morbidly obese patient who underwent TKA. After the operation, infection and a mechanical complication of periprosthetic fracture of the tibial component occurred. The infection made the treatment more difficult. The patient had to undergo several surgeries in several stages to address the post-surgical complications. TKA in obese patients leads to a higher risk of postoperative complications.

Risk assessment of amputation in patients with diabetic foot.

The prevalence of diabetes has increased dramatically over the past decade, especially in developing countries, reaching pandemic proportions. Although has been the most important factor influencing the prevalence of type 2 diabetes, the prevalence of type 2 diabetes is on the increase among younger adults. The subsequent rate of increase with age is variable, which is more evident in societies where the general prevalence of the disease is higher. Based on clinical and statistical data obtained from the patients who were admitted to The First and Second Surgery Wards in the Sibiu County Emergency University Clinical Hospital (Sibiu, Romania) and the Proctoven Clinic (Sibiu, Romania) between January 2018 and December 2020, the present study attempted to devise a risk score that can be applied for the benefit of patients. The ultimate aim was that this risk score may be eventually applied by diabetologists and surgeons to assess the risk of amputation in patients with diabetic foot lesions. An important part in the therapeutic management of diabetic foot injuries is the assessment of risk factors. Using this risk score system devised, the risk factors that were found to exert influence in aggravating diabetic foot injuries are smoking, obesity, dyslipidaemia, unbalanced diabetes mellitus (glycated haemoglobin ≥7.5%), duration of diabetes >5 years, hepatic steatosis and the co-existence of various heart diseases. To conclude, all these risk factors aforementioned can decrease the effectiveness of treatment and can have a significant impact on the quality of life, if they are not well known.

Cognitive and Behavioral Factors Predicting the Decision to Vaccinate against COVID-19 in Clinical Psychiatric Population-A Cross-Sectional Survey.

The spread of the COVID-19 virus created more than a medical crisis, while it also negatively affected the mental health of the general population. This context increased the vulnerability of the psychiatric population. While research interest highly targeted vaccine hesitancy and acceptance, many studies focused on trust issues-both in vaccine efficacy and in communication with authorities. Less is known about the psychological underpinnings of the COVID vaccination decision, specifically in the high-uncertainty circumstances due to the novelty of the virus. In a cross-sectional study, we investigated the predictive value of several cognitive (perceived risk, vulnerability, uncertainty, and trust in one's decision) and behavioral (previous vaccinations, social media use, and practicing preventive behavior) factors, for the vaccination decision against COVID-19, for 252 psychiatric inpatients (data collected between September 2021 and February 2022). Demographics and diagnostics were also considered. We found a significant relationship between the "Perceived risk of vaccination" and the choice of vaccination (χ2(2, N = 252) = 58.59, p ≤ 0.001), and between the "Trust in own decision to vaccinate" and the decision to vaccinate (χ2(2, N = 252) = 31,5, p ≤ 0.001). The overall regression model was statistically significant (χ2 (9, N = 252) = 97.1, p < 0.001), with between 30% and 45% of the variance in the odds of a positive decision explained by the predictor set. The model coefficients analysis showed that an individual with a psychiatric disorder but with higher confidence in their decision had significant (p < 0.001) increased odds of the decision to vaccinate against COVID-19 by 893%. A former voluntary vaccination did not significantly associate with the decision to vaccinate against COVID-19 (χ2(1, N = 252) = 2.74, p > 0.05) in this special population. No other behavioral factors, diagnosis, or demographics were significant as predictors, for the clinical psychiatric population surveyed, except the educational level. Implications for future vaccination acceptance of this special population are discussed.

Has-miR-129-5p's Involvement in Different Disorders, from Digestive Cancer to Neurodegenerative Diseases.

At present, it is necessary to identify specific biochemical, molecular, and genetic markers that can reliably aid in screening digestive cancer and correlate with the degree of disease development. Has-miR-129-5p is a small, non-coding molecule of RNA, circulating in plasma, gastric juice, and other biological fluids; it plays a protective role in tumoral growth, metastasis, etc. Furthermore, it is involved in various diseases, from the development of digestive cancer in cases of downregulation to neurodegenerative diseases and depression. Methods: We examined meta-analyses, research, and studies related to miR-129-5-p involved in digestive cancer and its implications in cancer processes, as well as metastasis, and described its implications in neurological diseases. Conclusions: Our review outlines that miR-129-5p is a significant controller of different pathways, genes, and proteins and influences different diseases. Some important pathways include the WNT and PI3K/AKT/mTOR pathways; their dysregulation results in digestive neoplasia and neurodegenerative diseases.

Resting-state frontal, frontlateral, and parietal alpha asymmetry:A pilot study examining relations with depressive disorder type and severity.

Introduction: The search for biomarkers has been central to efforts of improving clinical diagnosis and prognosis in psychopathology in the last decades. The main approach has been to validate biomarkers that could accurately discriminate between clinical diagnoses of very prevalent forms of psychopathology. One of the most popular electrophysiological markers proposed for discrimination in depressive disorders is the electroencephalography (EEG)-derived frontal alpha asymmetry. However, the validity, reliability and predictive value of this biomarker have been questioned in recent years, mainly due to conceptual and methodological heterogeneity. Methods: In the current non-experimental, correlational study we investigated relationship of resting-state EEG alpha asymmetry from multiple sites (frontal, frontolateral, and parietal) with different forms of depressive disorders (varying in type or severity), in a clinical sample. Results: Results showed that alpha asymmetry in the parietal (P3-P4) was significantly higher than in the frontal (F3-F4) and frontolateral sites (F7-F8). However, we did not find significant relations between alpha asymmetry indices and our depressive disorder measures, except for a moderate positive association between frontolateral alpha asymmetry (eyes-closed only) and depressive disorder severity (determined through clinical structured interview). We also found no significant differences in alpha asymmetry between participants, depending on their depression type. Discussion: Based on results, we propose the parietal and frontolateral asymmetry indices to form hypotheses that should not be abandoned in the depression markers research, but worth for further experimental research. Methodological and clinical implications of the current findings are discussed.

Therapeutic Perspectives for Microbiota Transplantation in Digestive Diseases and Neoplasia-A Literature Review.

In a mutually beneficial connection with its host, the gut microbiota affects the host's nutrition, immunity, and metabolism. An increasing number of studies have shown links between certain types of disease and gut dysbiosis or specific microorganisms. Fecal microbiota transplantation (FMT) is strongly advised for the treatment of recurrent or resistant Clostridium difficile infection (CDI) due to its outstanding clinical effectiveness against CDI. The therapeutic potential of FMT for other disorders, particularly inflammatory bowel diseases and malignancies, is currently gaining more and more attention. We summarized the most recent preclinical and clinical evidence to show the promise of FMT in the management of cancer as well as complications related to cancer treatment after reviewing the most recent research on the gut microbiota and its relationship to cancer.

Biomechanical Study of the Osteoporotic Spine Fracture: Optical Approach.

BACKGROUND AND OBJECTIVES: Osteoporotic spine fractures represent a significant factor for decreasing quality of life in the elderly female population. Understanding the mechanisms involved in producing these fractures can improve their prevention and treatment. This study presents a biomechanical method to produce a vertebral fracture, conducted on a human spine segment, observing the displacements and strains in the intervertebral disc, endplate, and vertebral body. MATERIALS AND METHODS: We performed two tests, one corresponding to an extension loading, and the second to an axial loading. RESULTS: The maximum displacement in the target vertebral body presented higher values in the case of the extension as compared to the axial strain where it mainly occurred after the fracture was produced. The strains occurred simultaneously on both discs. In the case of the axial strain, due to the occurrence of the fracture, the maximum value was recorded in the spine body, while in the case of the extensions, it occurred in the neural part of the upper disc. The advantage of this method was that the entire study was an experiment, using optical methods, increasing the precision of the material data input. CONCLUSIONS: The research method allowed recording in real time of a larger amount of data from the different components of the spine segment. If there was an extension component of the compression force at the moment of the initial loading, part of this load was absorbed by the posterior column with higher mechanical resistance. After the maximum capacity of the absorption was reached, in both situations the behavior was similar.
