Coronavirus disease (COVID-19) is a viral pneumonia that is found in China and has spread globally. Early diagnosis is important for effective and timely treatment. Thus, many ongoing studies attempt to solve key COVID-19 problems such as workload classification, detection, and differentiation from other pneumonia and healthy lungs using different imaging modalities. Researchers have identified some limitations in the deployment of deep learning methods to detect COVID-19, but there are still unmet challenges to be addressed. The use of binary classifiers or building classifiers based on only a few classes is some of the limitations that most of the existing research on the COVID-19 classification problem suffers from. Additionally, most prior studies have focused on model or ensemble models that depend on a flat single-feature imaging modality without using any clinical information or benefiting from the hierarchical structure of pneumonia, which leads to clinical challenges, and evaluated their systems using a small public dataset. Additionally, reliance on diagnostic processes based on CT as the main imaging modality, ignoring chest X-rays. Radiologists, computer scientists, and physicians all need to come to an understanding of these interdisciplinary issues. This article first highlights the challenges of deep learning deployment for COVID-19 detection using a literature review and document analysis. Second, it provides six key recommendations that could assist future researchers in this field in improving the diagnostic process for COVID-19. However, there is a need for a collective effort from all of them to consider the provided recommendations to effectively solve these issues.

SARS-CoV-2 is a new pandemic infection that affects at the beginning the upper respiratory system, and, successively, all the organisms, due to cytokine storm, with serious consequences that can reach death. The aim of this work was the observation of the nasal mucosa of enrolled 60 patients, resulting negative for two weeks to the molecular swab for SARS-CoV-2, versus the control group. Rhino-fibroscopy and nasal cytology of nasal mucosa were performed for both the investigated groups. The observation of the samples showed the occurrence of plasmablastic lymphocytes and Downey II lymphocytes type. The former type of lymphocytes was prevalent against the second one, probably because of an immunological “scar”. The rhino-fibroscopy showed a “pseudo ischemia of nasal submucosa” at pre and pericranial levels, not occurred in the control group.The occurrence of atypical lymphocytes in the nasal smear was analog to that observed in the blood peripheral smear, probably caused by mechanisms of local immune reaction and dysregulation like those observed in other virus infections. Our findings suggest that the nasal mucosa study through the nasal cytology, can represent an important predictive tool of the SARS-CoV-2 infection.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) appeared in December 2019 in China and has rapidly become a major global health concern. Patients with end-stage renal disease receiving dialysis treatment are very exposed to the SARS-CoV-2 during their frequent visits to healthcare facilities and immune induced by uremia. The aim of our work was to describe the particularity of COVID-19 infection in hemodialysis patients in sub-Saharan Africa and in Ziguinchor, south of Senegal, particularly. To do this, we conducted a monocentric prospective study over a period of 16 months at the Ziguinchor hemodialysis center and compared our results to a study that focuses on the seroprevalence of SARS-CoV-2 in chronic hemodialysis patients. We found a low prevalence of COVID-19 infection while the majority of our patients were in contact with the virus.

This paper is a study of the nuclear Equation of State (EOS) of cold nuclear matter with the B3Y-Fetal effective interaction in its CDM3Y density-dependent version within the framework of Hartree-Fock approximation. The well-known saturation properties of both symmetric and asymmetric nuclear matter are well-reproduced in this work. Using the CDM3Y-K approach, this study has evolved a new set of user interactions, some of which are CDB3Y1-, CDB3Y2-, CDB3Y3-, CDB3Y4-, CDB3Y5-, CDB3Y6-Fetal interactions with corresponding incompressibilities K0 = 188, 204, 217,228, 241 and 252 MeV respectively, in excellent agreement with those of the M3Y-Paris and M3Y-Reid effective interactions. For asymmetric nuclear matter, the new set of interactions has produced the symmetry energy Esym = 32.00 MeV with an associated slope parameter L = 55 MeV at a saturation density ρ = 0.17fm−3 and asymmetry parameter δ = 1.00 (pure neutron matter) in good agreement with the standard values obtained from coupled channel analysis of charge exchange reactions, statistical multifragmentation model and terrestrial Nuclear Physics experimental analyses. Furthermore, the new set of interactions has been found to have bright prospects in a nuclear reaction as the real folded potential computed with the CDB3Y6-Fetal interaction within the framework of double folding potential has been found to be good and similar to that of CDB3Y6-Paris whose optical potential has a repulsive direct component.

Introduction: Child Protection Services (CPSs) are dedicated to providing protection and responding to any threats a child could face as children worldwide could be abused. Recently, the COVID-19 pandemic affected all aspects of life. Procedures implemented to restrict the spread of the disease (such as reduced access to services, school closure, and social distancing measures) had an impact on child life and maltreatment. Therefore, it is important to know the impact of this pandemic on child abuse and protection. Aim and rationales: This study aimed to assess the impact of COVID-19 on CPSs in Oman by studying the change in the number of reported cases of child abuse and the change in the reporting procedure at the Ministry of Social Development (MOSD). In addition, know the impact of the restriction measures on child rights and risk factors of child maltreatment based on CPSs workers’ opinions and experience. To understand the adaptation of the CPSs to the change in work and life environment imposed by COVID-19. Method: A cross-section study was conducted using a semi-structured questionnaire, that was distributed to the workers involved in the CPSs at the MOSD in Oman. Data also were collected from the statistical bulletins on the Ministry’s website. Results: COVID-19 pandemic was not found associated with a significant change in the number and type of child abuse cases reported to the MOSD. The reporting procedures also did not change. In addition, the pattern of child abuse types did not change before and during the pandemic, as neglect cases were the most. The participants judged the restriction measures affecting family life through separation, cyber abuse, and reduced educational support. With regard to intervention and follow-up procedures, the main difference was in the communication processes by using online communication methods and reducing the fieldwork for mild cases.Conclusion: CPSs in Oman were not much affected by the COVID-19 pandemic, which may reflect the success of this system in dealing with the restriction measures. However, more solutions should be developed to adapt to these circumstances in the future altogether.

This article investigates the viability of SARS-CoV-2 and its dependence on pH levels, specifically focusing on the difference between the pH stability intervals for the coronavirus and human blood. Human blood typically maintains a pH range of around 7.35 to 7.45, while SARS-CoV-2 exhibits stability within the pH range of 6.0 to 6.5. The study aims to elucidate the critical role of hemoglobin in maintaining pH balance and explores its implications for viral susceptibility. The findings emphasize the importance of reinforcing the alkalinity of the medium as a means to weaken the virus. The research contributes to the understanding of pH-dependent mechanisms in viral infections and provides valuable insights for the development of potential therapeutic strategies.

This is a literature review study focusing on the expression of p53 and WT1. Both the p53 and WT1 proteins are tumor suppressors, which means that they play a role in preventing the progression into cancerous ones. If these proteins are altered or deleted, they lose the ability to carry out their role, which might result in the development of cancer. The primary objectives of this study were to review the literature regarding the expression of both p53 and WT1 and to investigate their prognostic significance; and to discuss our new hypothesis regarding the ratios of expression of WT1/p53, as well as our model regarding acute myeloid leukemia. In brief, the objectives were to make the focus in the suggested hypothesis as well as collecting the supportive literature. According to the findings of the current research, the level of expression of WT1 and p53 can indicate either a favorable or unfavorable prognosis for cancer patients. Further, we demonstrated that the expression, not just as a quality variable but also as a quantity variable, may have a more substantial explanation in the progression of tumors than we had previously thought. According to the theory that was derived from this research, if the expression of WT1/p53 (the expression is given as a ratio) is somewhere around 4, then p53 acts as though it were wild type and offers protection against tumors. In order to verify this idea, we need to do additional study.

In the search for a solution to the Riemann Hypothesis, we have studied an approach that connects the Riemann Problem with physical modeling that refers to statistical mechanics.Thus, we study the relation between a truncation of the Riemann ξ function in the variable z = 1-1/s, where s is the usual complex variable (s=Re(s)+i·Im(s) = ρ + i·t) and the partition function of a ferromagnetic spin 1/2 model on a circle C with long-range interaction, to give a concrete look at a strategy for a possible proof of the Riemann Hypothesis. 

Background: The socioeconomic impact of drug and substance abuse on secondary school students in Nigeria is yet to be fully evaluated even in the face of the current surge in abuse of substances among the younger folks who constitute more than half of the entire population.Objective: This study narratively reviewed the studies on the socioeconomic impacts of drug and substance abuse on secondary school students and studies by researchers in Nigeria. Methods: The study was a narrative review of the literature covering the socioeconomic impacts of drug and substance abuse on secondary school students in Nigeria from 1980 to 2023. Data were extracted and summarized with descriptive statistics. Results: All the studies took place between 2012 and 2023; 6 (100%). The studies carried out were all observational studies 6 (100%). All the studies fell below average in the benchmark for the hierarchy of evidence-based studies. The studies mostly took place in the South-West 3 (50.00%), while 1 (16.67%) took place in the South-East, North-West, and North-Central respective regions of Nigeria.Conclusion: The available studies done on the impacts of drug and substance abuse focused more on the social impacts, with little or no attention to the economic effect. The available studies however remain at the observational level in the evidence-based ladder. Future Research on the reviewed theme should focus on the economic implications of the social effects of drug and substance abuse on secondary school students in Nigeria.

Background: Exclusive breastfeeding has great benefits for both the mother and the child. Few studies have been carried out on interventions to improve Exclusive Breastfeeding (EBF) practice by childbearing mothers. No study has formulated and/or implemented a hospital-based maternal counseling guide intervention to improve EBF practice. This baseline study assessed the knowledge, attitude, and practice of EBF on mothers who were enrolled in antenatal clinics for a cluster randomized trial and the disparity in the knowledge of EBF based on lactation, age, sex, and source of income.Methods: We formulated a hospital-based counseling guide on exclusive breastfeeding, which is under implementation by prenatal and nursing mothers, to promote EBF practice in the study area. A cross-sectional study was conducted in two hospitals randomly selected from twelve hospitals in Anambra State. The study was among pregnant women who were in their second trimester. The data collection took place from March to April 2022. The data were analyzed using descriptive statistics and Chi-Square. The test of significance was set at p < 0.05.Results: The control and the intervention arms had an equal number of enrolees (144) each and more than half of the participants were between the ages of 23 – 32 years. The majority of the participants showed adequate knowledge of exclusive breastfeeding as over 90% knew that EBF is important and capable of improving their baby's immunity. The participants demonstrated a positive attitude to exclusive breastfeeding and they had a significantly high level of practice of daily consumption of galactagogues. The study suggested that the majority did not practice breast milk extraction mainly because the process of extraction is painful and some do not know how to carry out the extraction.Conclusion: The mothers have the requisite knowledge of the benefits of exclusive breastfeeding to their infants and themselves. However, they do not practice EBF. Interventions to improve EBF practice should focus on educating mothers on proper breast milk extraction and storage techniques.

Background: In light of the COVID-19 pandemic and the health crisis left in its wake, our goal is to develop extensive machine-learning techniques to provide a clear picture of the treatment, and possible mistreatment, of specific patient demographics during hospital triaging.Objective: We aim to reveal whether a patient’s treatment and hospital disposition is related to the following attributes - Emergency Severity Index (ESI), gender, employment status, insurance status, race, or ethnicity which our 100 MB dataset included.Materials and methods: Our work is separated into two parts - the classification task and data analysis. As part of the classification task, we used the k-Nearest-Neighbor classifier, the F1-score, and a random forest. We then analyze the data using SHapley Additive exPlanations (SHAP) values to determine the importance of each attribute.Results: Our findings show that significance varies for each attribute. Notably, we found that patients with private insurance programs receive better treatment compared to patients with federal-run healthcare programs (e.g. Medicaid, Medicare). Furthermore, a patient’s ethnicity has a greater impact on treatment for patients under 40 years of age for any given ESI level. Surprisingly, our findings show language is not a barrier during treatment.Discussion and conclusion: We, therefore, conclude that although hospitals may not be doing so intentionally, there is a systemic bias in hospital triaging for specific patient demographics. For future works, we hope to aggregate additional patient data from hospitals to find whether specific demographics of patients receive better healthcare in different parts of the United States.

This review paper investigates the relationship between creatine supplementation and the Akt/mTOR pathway, focusing on their impact on muscle performance. The Akt/mTOR pathway is a crucial signaling pathway that regulates muscle protein synthesis and hypertrophy in response to growth factors, nutrients, and mechanical stimuli. Recent evidence suggests that creatine supplementation can influence anabolic signaling pathways, including the phosphorylation of p70S6K, a downstream target of mTOR, leading to enhanced activation of the Akt/mTOR pathway. Additionally, creatine supplementation has been shown to increase intramuscular creatine and phosphocreatine levels, improving ATP availability during exercise and enhancing high-intensity muscle contractions. Understanding the complex regulatory mechanisms of the Akt/mTOR pathway is vital for optimizing muscle performance, as dysregulated signaling can hinder muscle protein synthesis and hypertrophic responses. This review highlights the potential of creatine supplementation to modulate the Akt/mTOR pathway, offering insights into its mechanisms and implications for muscle performance enhancement. By unraveling this connection, researchers and practitioners can develop targeted strategies to maximize muscle performance and promote adaptive responses in various exercise and athletic contexts.

Elbow hemiarthroplasty (EHA) is a highly effective procedure for treating various elbow joint disorders such as rheumatoid arthritis, osteoarthritis, and fractures involving the articular surface of the distal humerus. It involves replacing the entire distal humerus with a prosthesis and reattaching the supporting soft tissues. The EHA provides significant pain relief, improves joint function, and increases patient satisfaction, with minimal complications that can be easily managed. This case study demonstrates the value of EHA as a viable treatment option for distal humerus fractures in older adults with moderate activity levels, as a superior alternative to osteosynthesis.

Background: 800 women die and 2.6 million stillbirths occur worldwide related to pregnancy complications. Racial/ethnic disparities in pregnancy-related mortality have continued to be significantly higher among black than whites due to various factors. We sought to investigate complications among pregnant women of different race/ethnicity.Methods: Cross-sectional observational study of 2030 obstetric cases randomly selected for the period January 1 to December 31, 2021. Data was collected from the hard copy and electronic inpatients’ records. Analysis was performed using SPSS version 23. Descriptive statistics analyzed the pregnancy complication frequencies, standard deviations, range, minimum and maximum values. Maternal characteristics were analyzed using an independent samples t-test. Maternal characteristics were evaluated using the two samples t-test. The odds ratios and confidence intervals were calculated as measures of association between ethnicity/race and pregnancy complications using a binary logistic regression model. Confidence interval was set at 95% and p < 0.05 (2-tailed) was considered statistically significant.Results: 76.25% of Chinese and 67.86% of Zambians were affected by one or more complications. The mean ± standard deviation for MGH [age (26.69 ± 7.33), gravidity (3.35 ± 2.08), and parity (2.07 ± 1.68)] and for 2nd affiliated hospital was [age (30.04 ± 4.29), gravidity (2.19 ± 1.38) and parity (0.45 ± 0.55)]. Prevalence of top five pregnancy complications in the Chinese group was gestational diabetes mellitus at 18.41%, hypothyroidism at 15.91%, oligohydramnios at 14.39%, premature rupture of membranes at 12.17%, and anemia at 5.73%. The prevalence of the top five pregnancy complications in the Zambian group was preeclampsia at 13.80%, PIH at 12.74%, PROM at 12.45%, eclampsia at 7.53%, and placenta abruption at 7.43%. Statistical significance findings were noted as follows: Oligohydramnios [OR 0.02, CI (0.01 - 0.05), p = 0.000], placenta praevia [OR 0.08, CI (0.01 - 0.61), p = 0.015], preeclampsia [OR 13.10, CI (7.22 - 23.78), p = 0.000], placenta abruptio [OR 79.73, CI (11.07 - 574.38), p = 0.000], PIH [OR 11.95, CI (6.57 - 21.73), p = 0.005], eclampsia [OR 162.90, CI (10.08 - 2631, p = 0.000), PPROM [OR 0.03, CI (0.00 - 0.45), p = 0.012], GDM [OR 0.11, CI (0.07 - 0.17), p = 0.000], hypothyroidism [OR 0.01(0.00-0.03), p = 0.000], anemia [OR 0.18, CI (0.92-0.34), p = 0.000], ICP [OR 0.03, CI (0.00 - 0.48), p = 0.013], syphilis [OR 7.17, CI (2.14 - 24.02), p = 0.001], UTI [OR 22.55, CI (3.04 - 17.26), p = 0.002], HBV [OR 0.05, CI (0.00 - 0.86), p = 0.039] and GBS [OR 0.06, CI (0.00 - 1.11), p = 0.059].Conclusion: Highest odds for obstetrical and infection-related pregnancy complications were associated with Zambian cases. The highest odds for medical complications were associated with Chinese cases.

Targeted screening for Cytomegalovirus (CMV) in Deaf and Hard of Hearing (DHH) children is now internationally recommended. With newborn genomic screening for DHH children a future possibility, the commercially-available human genomic DNA collection kit (ORACollect, Oragene OCR-100) could enable one single sample to screen for CMV and genetic causes of deafness at scale with minimal additional costs. Our pilot study validated ORACollect against Copan FLOQswabs® (gold standard clinical procedure) for detecting CMV using 15 sets of saliva samples from 14 infants/children, comparing CMV PCR results using different testing protocols. ORACollect stored at room temperature had high sensitivity (up to 89%), specificity (up to 80%) and percent agreement (up to 86%) in detecting CMV DNA compared to FLOQswabs®. This suggests that ORACollect is an appropriate alternative to FLOQswabs® for collecting viral CMV DNA for PCR testing, independent of the DNA extraction approach. This could be revolutionary in facilitating dual genomic and viral screening in newborns and would enable CMV screening in non-tertiary hospital settings where laboratory facilities are not available.

Monkeypox is a sylvatic zoonotic sickness that initially affected tropical rainforest areas in the west and vital Africa earlier than spreading to other places. Its miles carried with the aid of the Monkeypox virus member of orthopoxvirus circle of relatives. The clinical features of the infection resembles to smallpox. The primary animal to human transmission is the cause of most people of human Monkeypox ailments. Severe rodent species and non-human primates function hosts for the virus. Transmission can manifest with infected people, animals or objects into contact with bodily fluids, sores on the skin or inner mucosal surfaces just like the mouth or throat, or breathing droplets. The incubation length for Monkeypox usually lasts 6 to 13 days, even though it could last as long as 21 days. The ailment is often self-proscribing, with signs and symptoms generally clearing up on their own inside 14 to 21 days. Signs can range from moderate to extreme, and lesions may be itchy or painful. Due to the discontinuation of recurring smallpox vaccination which supplied some pass- safety in past, populations have become more liable to Monkey pox. The outbreak of Monkeypox virus due to the fact that may additionally, 2022 has created a worldwide risk of the virus. In the present review, Monkeypox epidemiology, severity, therapeutics, vaccination and its transmission to non-endemic countries has been considered. Special care and guidelines may help in the containing in the spread of the infections to the non endemic countries.

Genistein is an isoflavone glycoside that provides a variety of health advantages. The possibility of cancer chemopreventive drugs derived from natural sources, such as polyphenols, may constitute a novel, cost-effective strategy to reduce the rising burden of cancer throughout the world. A soy-rich diet was linked to cancer prevention in several epidemiological studies, which was explained by the presence of the phenolic component genistein in soy-based foods. Inhibiting metastasis and changing apoptosis, the cell cycle, and angiogenesis are the key ways that genistin fights various cancers. It acts as a chemotherapeutic agent against different types of cancer, mainly by altering apoptosis, the cell cycle, and angiogenesis and inhibiting metastasis. This study critically evaluates the literature that is currently available on the therapeutic benefits of genistin for various cancers.

Introduction: Total bronchoalveolar lavage (BAL) continues to be the treatment of choice for alveolar proteinosis (AP), facilitating the removal of lipoprotein material. The purpose of this article is to evaluate the impact of haemodynamic, biochemical, and respiratory parameters, as well as the complications and evolution of patients undergoing this procedure. Methods: Retrospective, observational, and descriptive study of BAL. The technique was performed in the Intensive Care Unit. Blood gases, blood pressure, central venous pressure, body temperature, and fluid balance were analyzed. Results: Including eight patients, thirty-eight BAL were performed from 2008 to 2021. The mean instillation of saline at each session was 13.464 ± 4.002 ml per lung. No significant changes were observed before and after BAL in heart rate and blood pressure. Mean central venous pressure increased by 2.59 cm H20. The pO2 initial was 126 mmHg with a final mean of 69.7 mmHg, with statistical significance. The pCO2, HCO3 and pH parameters remained stable. Complications were observed during fifteen of the thirty-eight BAL (nine with arterial hypotension, three with glottic oedema, one acute pulmonary oedema, one pneumothorax, and one cardiorespiratory arrest). In terms of evolution, one case had a clinical-radiological resolution, one case of exits, one required lung transplantation, and the remaining five remained stable. Conclusion: This study demonstrates that the procedure, is well tolerated haemodynamically and that the biochemical alterations to which the patient is subjected are not compromised. With few complications and good results in delaying the progression of AP.

Background: Cardiomyopathy is primarily a disorder of the cardiac muscle that causes myocardial dysfunction and is not the result of disease or dysfunction of other cardiac structures, systemic arterial hypertension and valvular stenosis or regurgitation. Aim: The present study aimed to determine the prevalence of vitamin D deficiency and its correlation with the severity of heart disease in patients with dilated cardiomyopathy (DCMP). Method: 70 ECHO-proven DCMP cases were enrolled from the medicine/ cardiology department of LHMC & associated hospitals and ABVIMS & Dr. RML Hospital, New Delhi from November 2019 to October 2021. DCMP patients with ages more than 18 years who were willing to give consent and does not meet any of the exclusion criteria were enrolled in this study. Results: Mean age of idiopathic DCMP patients was 48.3 ± 15.2. There were more males 48 (69%) than females 22 (31%). The mean ejection fraction was 26.6 ± 7.3, while the mean fractional shortening was 17.6 ± 3.1. Vitamin D deficiency was observed in 90% of patients, among which 68.5% were having moderate vitamin D deficiency and 10% were having severe vitamin D deficiency. Conclusion: In our study, vitamin D levels were inversely correlated with the severity of heart disease in DCMP patients.

Objective: To evaluate the surgical management of myomas at the Teaching Hospital of Angré according to the FIGO (International Federation of Gynecology and Obstetrics) classification.Patients and methods: This was a cross-sectional study at the Teaching Hospital of Angre from January 1, 2020, to December 31, 2022. Patients whose operative indication was clearly identified were included in the study. Incomplete files were not included. The variables studied were anthropometric parameters, clinical characteristics of myomas, and surgery. Due to the large size and multifocal location of uterine myomas, the therapeutic option remained surgery by laparotomy.Results: Most patients were over 35 years old (71.5%) and nulliparous (52.8%). The first indication for surgery was menometrorrhagia (88.6%), followed by the desire for motherhood (37.8%) and dysmenorrhoea (20.2%) for myomas most often FIGO type 4 (p = 0.0031). Myomectomy under cervical-isthmic tourniquet was the most common procedure for FIGO type 4 myomas (66.1%; p = 0.0543). Hysterectomy was most frequently performed for FIGO type 7 myomas (43.9%; p = 0.0543). For myomectomy, the first complication was anaemia (3.5%) followed by uterine suture haemorrhage (1.7%) (p = 0.5139).Conclusion: Our surgical practice at the Teaching Hospital of Angre is in accordance with FIGO recommendations. However, an effort should be made to promote the minimally invasive surgical approach (laparoscopic, hysteroscopic, transvaginal ablation) for small fibroids (≤ 5 cm) or FIGO type 0 to 3, which is not very frequent in our current practice.
