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.

With each passing year a new record for global emissions is set (1) and policymakers and utility companies must embrace all avenues for decarbonization of energy. Universal adoption of electrification for every building and home by 2050 (2) is not practical, a balance must be struck between an equitable transition to cleaner energy supplies and ensuring uninterrupted, safe delivery of energy to utility customers. Renewable Natual Gas (RNG) is a molecule-for-molecule replacement of traditional geological natural gas with tangible life cycle emissions reductions. California continues to lead the way, initially starting with the low carbon fuel standard (LCFS) which aimed to reduce the carbon intensity of transportation fuel, and subsequently, Senate Bill 1440, which established RNG procurement goals including 12% RNG by 2030 (3). Other States are starting to adopt similar changes such as Oregon’s Senate Bill 98 and Colorado’s Senate Bill 21-264. As utilities attempt to transition the energy network, they must never compromise system safety and reliability. Recognizing that raw biogas has dangerous levels of contaminants of concern (COC) and must be conditioned to pipeline quality, its important utility companies better understand the methods with which methane is extracted and the testing protocols used to confirm performance. This paper highlights the equipment, processes, and testing regime National Grid and its partner the New York City Department of Environmental Protection (NYC DEP) deployed as part of its Newtown Creek RNG project, which successfully began injecting RNG into the NYC gas distribution network in October 2022.

The field of Otolaryngology-Head and Neck Surgery (ENT) has seen tremendous progress in the development of advanced treatments for various ENT disorders in recent years. This progress has been driven by advances in technology and research, which have led to the development of new and improved surgical techniques, medications, and devices. As a result, patients with ENT disorders now have more treatment options than ever before, and the quality of care that they receive has improved significantly.

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.

Aim: The aim of this study was to evaluate the oral hygiene status of patients with fixed mechanotherapy appliances.Methods and materials: The following indices were used to evaluate the oral hygiene status of patients in orthodontic treatment: Gingival Bleeding Index (GBI), Plaque index (PI) and OrthoPlaque Index (OPI) at three intervals.T0 (day 1), T1 (15 days), T2 (30 days) for a period of one month.Results: 10 patients (15-30 years old) were selected for the study from among the orthodontic patients treated at the Department of Orthodontics & Dentofacial Orthopedics, AIDSR, Adesh University. Results showed that the mean PI decreased significantly from T0 to T1 & then from T1 to T2, GI decreased significantly from T0 to T1, but then, no significant difference could be found in GI from T1 to T2, OPI decreased significantly from T0 to T1, but then, no significant difference could be found in OPI from T1 to T2. No significant difference was observed between male and female patients for the PI, GI and OPI.Conclusion: Inadequate oral home care among orthodontic patients may increase their risk of gingivitis during treatment. As a result, oral hygiene instructions and a hygiene maintenance program must not be overlooked during orthodontic treatment.

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.

Non-Hodgkin Lymphoma is rarely diagnosed as spinal cord compression syndrome. Caused by an epidural mass, this complication is often encountered in the late stage of the disease. We report two cases presenting symptoms of low thoracic spinal cord compression due to an epidural tumor on the MRI. Possible complications that may occur and how to prevent adverse events during surgery are essential. This case is of special interest for being a low-incidence pathology in a rare location. The case is of high interest because of the importance of resecting the lesion to prevent sequels and the complexity of its management and highlights the importance of considering the diagnosis of this event.

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.

Cities with developing economies experience exhausted waste collection services, and inadequately managed and uncontrolled dumpsites; which is an ongoing challenge and many struggles due to weak institutions and rapid urbanization. The purpose of the research is to design and construct a smart garbage disposal system using a two-way power supply unit (that is, the electrical power supply unit and solar power supply unit) based on Arduino Nano that utilizes ATMEGA 328p microcontroller. Two pairs of ultrasonic sensors, the pair that faced upward detects the presence of garbage disposal agent at a close distance of (5 - 50) cm and then opens the lid while the other pair faced the inside of the container senses when the container is filled up and then closes the container until it is emptied are used.

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.

There are few reported cases of meningitis in pregnancy and presentation can be variable in each patient which may cause diagnostic challenges and potential delays in treatment. Here, we discuss a case of aseptic meningitis - a 36 years old Gravida 2 Para 1 pediatric physician with “the worst headache of her life” at 31+5 weeks of gestation. At presentation, she did not have any of the classic triads of meningitis (fever, neck stiffness, and/or a change in mental status) and did not report any neurological symptoms. In view of persistent headache, development of pyrexia, and evolving symptoms of photophobia, she was referred to a neurology specialist, and a lumbar puncture was performed. Findings were in line with meningitis and the polymerase chain reaction confirmed enterovirus meningitis. Although aseptic meningitis is rare, it should be considered as a differential diagnosis in patients with persistent complaints, development of associated symptoms of pyrexia, photophobia, and neck pain, as well as in patients with increased risk of exposure to viral illnesses.

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.

Proper feeding practices at an early age are the key to improving a child’s overall health and achieving developmental milestones. In Bangladesh, a large portion of rural girls become mothers before the age of 18. Past records show that most interventions are designed to improve infant and young child feeding practices targeting older mothers. That is why, this study has been designed with an aim to explore the perceptions and practices of infant and young children feeding among rural Bangladeshi mothers aged <19 years old. Data was collected through in-depth interviews and group discussions with a total of 40 adolescent mothers who have children aged 0-3 years. Data has revealed that the majority of the mothers hold very limited knowledge of nutrition and child nutrition but those who are educationally a bit ahead hold a little better knowledge. Participants are aware of breastfeeding but they all misinterpret the term ‘exclusive breastfeeding’ with other liquid food. It has also emerged that most of the mothers know the ideal timing of starting complementary feeding but very few of them actually understand what to feed children. In spite of having misconceptions and superstation rural adolescent mothers practice responsive feeding instead of force-feeding. No gender discrimination has been found regarding child feeding. The findings of the study pinpointed that mothers are unable to practice proper infant and child feeding due to a lack of knowledge and limited affordability. Educating girls & young mothers and improving financial security could be an effective way to promote improved infant feeding practices.

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.
