Advances in deep learning-based cancer outcome prediction using multi-omics data
No full textCancer prognosis reflects a complex biological process measured by multiple types of omics data. Deep learning frameworks have been proposed to integrate multi-omics data and predict patient outcomes in different cancer types, potentially revolutionizing cancer prognosis with superior performance. This minireview summarizes the advances in the strategies for multi-omics data integration and the performance of different deep learning models in prognosis prediction of diverse cancer types using multi-omics data published in the past 18 months. The challenges and limitations of deep learning models for predicting cancer outcomes based on multi-omics data are discussed
Peripheral perfusion index in critically ill COVID-19 and its association with multiorgan dysfunction
No full textIntroduction: Severe cases of COVID-19 presented a high incidence of multi-organ dysfunction syndrome (MODS) during their evolution. This was attributed to a theoretical cytokine storm, where microcirculatory disorders would play a fundamental role, causing these patients to present a sepsis-like pattern as observed in sublingual microcirculation studies. The evidence in this regard is controversial. The Peripheral Perfusion Index is a reliable method to continuously and non-invasively assess the microcirculatory bed, which assesses the pulsatile (PPI) component of the plethysmographic pulse curve.Methods: We conducted a prospective observational study to evaluate the behavior of the PPI in patients with severe respiratory failure due to SARS-CoV-2 and its association with SDOM.Results: We evaluated 60 patients with APACHE II 14.6 ± 4.4 and SOFA 4.7 ± 2.1. 55% of the patients presented SDOM. Perfusion monitoring showed IP values of 5.32 ± 1.87 that were associated with normal lactate levels of 1.49 mmol/L (min 0.89/ max 2.20 mmol/L). The PPI values between the living and the dead did not show a significant difference (p = 0.854) or the presence of SDOM.The PPI values between the patients who presented renal failure, hemodynamics, or perfusion disorders were determined by the presence of hyperlactatemia, and for those who did not present these characteristics, no statistical difference was found; neither when stratified by PaFiO2 ratio. Mortality was 55%.Conclusion: In our series of patients with severe pneumonia due to COVID-19, we found high PPI values, which would correspond to a pattern of capillary recruitment, and the associated organ injury could not be substantiated by this phenomenon

Deep vein thromboses as well as abnormalities of the cervical spine were ruled out initially. He was referred to a vascular surgeon and diagnosed with McCleery Syndrome after evaluation of the thoracic outlet with dynamic ultrasound testing. He was treated surgically for decompression of his venous thoracic outlet syndrome and has since made a full recovery
Fluctuation of serum creatinine: preoperative and postoperative evaluation of chronic kidney disease patients
No full textRenal impairment is one of the most severe non-communicable diseases around the world. Especially patients with diagnosed/newly diagnosed renal impairment who needed surgery are more focused on preoperative and postoperative preparation. Serum creatinine is the prime biochemical marker for assessing renal function and the level of impairment is widely measured by this marker as well as Glomerular Filtration Rate (GFR). Objective: Factors responsible for fluctuating serum creatinine during preoperative and postoperative periods and minimizing the process of serum creatinine is the ultimate goal of this study. Method: 37 patients participated in this cross-sectional study who were previously diagnosed/newly diagnosed. They were admitted to different tertiary-level hospitals for emergency or elective surgery. 15 patients were admitted in the renal function impairment stage and 22 were admitted as normal patients’. Values of creatinine at the pre-admission stage and 2nd/3rd post-admission follow-up were compared. Results: 0.41 was the average of 22 patients’ creatinine between pre-admission and 2nd/3rd follow-up. The responsible factor like prolonged staying, immobilization, co-morbidities, different preoperative antibiotics and NSAIDs were also inducers for creatinine elevation. After postoperative hemodialysis rapid decrease of creatinine is seen in normal patients but this decrease is very much minor in CKD-diagnosed patients. 
The time and the growth in physics
No full textIn this article, we made a research on the subject of Time and Growth. In the life, the Growth is seen as the increase of mass which operates during a certain period. In physics, it is the same. By the Growth, a physical body gets its density increased. The goal of this article is to calculate or predict the energy and force that a physical system can have at its total Growth. To study the Growth, we have defined some equations which help to evaluate the Growth internal force and energy. By the same way, we have also discovered that all physical systems in the Universe are connected by the same interaction. This interaction leads to the loss of density or mass. The Time is the consequence of its manifestation. For studying the effect of this interaction, we have calculated the density of the Universe. We found that the density of the Universe is equal to the density of a photon. In other words, the Universe is a huge photon. That means, like a photon, the Universe does not know the Time. It also means that the Universe is eternal. Its Expansion (not its growth) is due by the fact that, at the moment small systems inside to it grow, the Universe maintains its density constant like a photon. Do not confuse Growth and Expansion. The Growth is the increase of the density; and the Expansion is the increase of the volume without the change of density. The Universe does not know the Growth, it knows the Expansion. All these conclusions are detailed in the development of this article

High Magnification in Dentistry; Postural Benefits using Magnification Loupes to Improve Dental Work Performance
No full textStress, pain, injuries, and errors in dental procedures are situations highly linked to dentistry derived from multiple factors making this profession a profession with high physical and mental demand to achieve quality treatment without deteriorating the health of those who perform it, in this case, the dentist, the assistant, and hygienist.The effects of wrong postures, but above all, the lack of knowledge of the proper postures, the modeling of bad habits acquired during the training stage in dental school, and the lack of work guidelines that not only take into account the dentist but also to all the work staff and the methodological organization of dental tasks can be found in the scientific literature.Magnification devices are known to improve vision, precision, and ergonomics in dentistry; advances in the area of high magnification in dentistry are taking place by leaps and bounds. In recent years, a new magnification loupes design has appeared on the market, called ergonomic magnification loupes appeared that stands out from conventional Galilean and Keplerian through the lens (TTL) Flip-up loupes in terms of their postural benefits and is part of the arsenal of magnification loupes to consider in the market.The postural approach of high magnification equipment is necessary for professional practice, where the design of Ergonomic magnification loupes with consideration not only for magnification but also for the operator’s postural health which can have a significant impact on the performance and overall health of the dentist and hygienist, more if incorporated from the beginning of dental school education and training
The Ramifications of Loneliness: A Commentary
No full textLoneliness was a major concern of people during the recent COVID-19 pandemic. Now, that the pandemic is mainly gone, it is still a global issue. This commentary reviews the impact on that loneliness has on our cognitive, behavioral and affective functioning. These effects are described, along with the stigma that often accompanies loneliness and which makes it hard for people to acknowledge and admit that they are lonely, and seek help from healthcare professionals. This commentary, aside from describing the various negative implications of loneliness, highlights the need for society to address the issue. While it cannot be eliminated, the population can be taught how to recognize it, and how to offer assistance to those who struggle with it
Relationship between the Level of Spirituality and Blood Pressure Control among Adult Hypertensive Patients in a Southwestern Community in Nigeria
No full textBackground: Spirituality has been strongly associated with good blood pressure control as it forms a strong coping mechanism in hypertensive patients. This hospital-based cross-sectional study was done to determine the relationship between spirituality and blood pressure control among adult hypertensive patients in rural Southwestern Nigeria to achieve good blood pressure control.Method: The selection was done by systematic random sampling technique. Socio-demographic and clinical information were obtained through semi-structured interviewer-administered questionnaires. The level of spirituality was assessed using the Spiritual Perspective Scale. Data were analysed using the Statistical Package for Social Sciences version 20.0. Statistical significance was set at p ≤ 0.05.Results: The mean age of the respondents was 61.1 ± 11.1 years. More than half (52.6%) had a high level of spirituality and more than two-thirds (67.1%) of respondents had controlled blood pressure. Respondents with a high level of spirituality were 4.76 times more likely to have good blood pressure control {p < 0.001, 95% CI (1.05-14.99)} than those with a low level of spirituality. Conclusion: Proper understanding and effective utilization of this relationship will assist health professionals and researchers in the appropriate integration of this concept into patients’ holistic care with the aim of achieving better blood pressure control among hypertensive patients
