Throughout global efforts to defend against the spread of COVID-19 from late 2019 up until now, one of the most crucial factors that has helped combat the pandemic is the development of various screening methods to detect the presence of COVID-19 as conveniently and accurately as possible. One of such methods is the utilization of chest X-Rays (CXRs) to detect anomalies that are concurrent with a patient infected with COVID-19. While yielding results much faster than the traditional RT-PCR test, CXRs tend to be less accurate. Realizing this issue, in our research, we investigated the applications of computer vision in order to better detect COVID-19 from CXRs. Coupled with an extensive image database of CXRs of healthy patients, patients with non-COVID-19 induced pneumonia, and patients positive with COVID-19, convolutional neural networks (CNNs) prove to possess the ability to easily and accurately identify whether or not a patient is infected with COVID-19 in a matter of seconds. Borrowing and adjusting the architectures of three well-tested CNNs: VGG-16, ResNet50, and MobileNetV2, we performed transfer learning and trained three of our own models, then compared and contrasted their differing precisions, accuracies, and efficiencies in correctly labeling patients with and without COVID-19. In the end, all of our models were able to accurately categorize at least 94% of the CXRs, with some performing better than the others; these differences in performance were largely due to the contrasting architectures each of our models borrowed from the three respective CNNs.

Air pollution exposure is among the most prevalent reasons for environmentally-induced oxidative stress and inflammation, both of which are implicated in the central nervous system (CNS) diseases. The CNS has emerged as an important target for adverse health effects of exposure to air pollutants, where it can cause neurological and neurodevelopmental disorders. Air pollution includes various components of gases, particulate matter (PM), ultrafine particulate (UFPs), metals, and organic compounds. An important source of PM and UFPM in the ambient air is associated with air pollution-related trafficking, and primarily diesel exhaust particles (DEPs). Controlled animal studies and epidemiological studies show that exposure to air pollution, and in particular urban air pollution or DEPs, may lead to neurotoxicity. In specific, exposure to air pollutants as an important factor may be in neurodevelopmental disorders (eg Autism) and neurological disorders (eg.., Alzheimer’s Disease (AD)). The most noticeable effects of exposure to air pollutants in animals and humans are oxidative stress and neurodegeneration. Studies in rats exposed to DEPs showed microglial activity, increased lipid peroxidation, and neuronal accumulation in various areas of the brain, especially the olfactory bulb (OB) and the hippocampus (HI). Disorders of adult neurogenesis were also found. In most cases, the effects of DEP are more pronounced in male mice, probably due to lower antioxidant capacity due to less expression of paraoxonase 2.

Introduction: Preeclampsia constitutes a public health problem in our region. According to the WHO, it is the third cause of maternal mortality after severe hemorrhages, infections and is responsible for morbidity and high fetal mortality. The aim of this study was to improve on the management of severe preeclampsia at the University Hospital Center of Mother and Child (UHCMC) in N’Djamena.Patients and method: It was a prospective and descriptive survey of 3 years duration, from January 01st, 2017 to December 31st, 2019. Included in our study were, all patients admitted for severe preeclampsia and agreed to participate in the study. Epidemiological, clinical, therapeutic and prognostic studies were conducted. The data collected was analyzed using SPSS 18.0 software.Results: During the study period, 13599 pregnant and parturients were admitted to the Gynecology-Obstetrics department of the UHCMC, among whom 406 cases of severe preeclampsia, with a frequency of 2.9%. The patients were young (23.2 years), married (96.3%), primipara (61.3%), referred (64.3%) without antenatal care in 47.9% of cases. Functional signs were dominated by headaches with 34.0% of cases. The proteinuria was ≥ 3 crosses in 83.7% of cases. Patients had received magnesium sulfate in 98.3%, the delivery mode was cesarean in 64.0% of cases. Principal morbidity was eclampsia (40.8%) and fetal was prematurity (36.4%). Maternal lethality was 11.1% and fetal mortality was 19.9% cases.Conclusion: Severe preeclampsia is frequent in the UHCMC in N’Djamena. It is responsible for high maternal and fetal mortality. The practice of quality antenatal care, could prevent the occurrence of complications and improve the maternal-fetal prognosis.

Background: Pre-eclampsia and eclampsia have remained a major global public health threat in contributing significantly to maternal and perinatal morbidity and mortality. Based on the inverse relationship between serum 1,25(OH)2D3 levels and plasma renin activity found previously, it is speculated that 1,25(OH)2D3 might be a negative endocrine regulator of renin production in vivo. During pregnancy, vitamin D may play a role in implantation and placental function potentially due to angiogenic, immunomodulatory, and antiinflammatory effects. Vitamin Ddeficiency can affect the health of both mother and fetus by increasing the production of inflammatory cytokines and stimulating the activity of T-regulating cells. Vitamin D is emerging as a promising agent for pre-eclampsia prevention. Aims and objectives: The objective of this study is to compare the vitamin D levels in pre-eclamptic and healthy non-pre-eclamptic pregnant women in labor and find out the relationship between vitamin D levels and pre-eclampsia. Methodology: The present cross-sectional study was carried out on pregnant women with pre-eclampsia in labor. For each case with pre-eclampsia, one uncomplicated, normotensive pregnant woman in labor was taken as control. On admission to the labor room detailed history, physical examination followed by thorough obstetrics and systemic examination was done. Required investigations were done including vitamin D and calcium levels. Maternal and fetal condition was monitored during labor/cesarean section, mode of delivery, maternal and fetal outcomes were recorded. After delivery, 2cc of cord blood was collected in a serum tube and sent for vitamin D levels. Data was collected and analyzed statistically using Epi-info version 7.1.Results: It was observed that the patients in both groups were comparable with respect to demographic and obstetrics characteristics except for significantly high BP in group I. Vitamin Ddeficiency (i.e. < 20 ng/ml) was significantly more in group I as compared to group II and the difference was highly significant (p < 0.0001). Similarly, the mean maternal calcium levels were significantly lower in group I in comparison to group II (p < 0.0001) i.e. the mean maternal calcium level in group I and group II were 8.03 ± 0.94 and 9.19 ± 0.67 respectively. It was also observed that the level of 25-OH-D in neonates of preeclamptic women was significantly lower than for those of the normal pregnant women (p < 0.0001). Conclusion: Vitamin D deficiency is highly prevalent in all parts of the world. Pregnant women and neonates are highly vulnerable to vitamin D deficiency. Preeclampsia is indeed associated with lower vitamin D levels and the pathophysiology of pre-eclampsia involves vitamin D and calcium metabolism through their role in immunomodulation, angiogenesis and anti-inflammatory effects. From the present study, it was observed that vitamin D and calcium levels were significantly lowered in women with pre-eclampsia as compared to those of the normotensive pregnant women. So early detection of vitamin D and calcium deficiencies may be helpful in preventing occurrence of PET and its complications.

The commonest etiology of acute kidney injury (AKI) is Sepsis that results in an escalation of morbidity and mortality in the hospital intensive care units. Existentially, the therapy of septic AKI rather than being definitive or curative is just supportive, without tackling the pathophysiology. Usually, Sepsis gets correlated with systemic inflammation, along with the escalated generation of Reactive oxygen species (ROS), in particular superoxide. Simultaneously liberation of nitric oxide (NO) subsequently reacts with the superoxide, thus, resulting in the generation of reactive nitrogen species (RNS), that is mostly peroxynitrite. This sepsis stimulated generation of ROS in addition to RNS might cause a reduction in the bioavailability of NO that modulates microcirculation aberrations, localized tissue hypoxia as well as mitochondrial impairment, thus starting a vicious cycle of cellular damage which results in AKI. Here we conducted a systematic review utilizing search engine PubMed, Google scholar; Web of science; Embase; Cochrane review library utilizing the MeSH terms like septic AKI; ROS; inducible nitric oxide synthase (iNOS); nicotinamide adenine nucleotide phosphate(NADPH)oxidase complex; Oxidative stress; Renal medullary hypoxia; Hypoxia inducible factor1; hypoxia responsive enhancer A; mitochondrial impairment; Intrarenal oxygenation; urinary oxygenation; erythropoietin gene; RRT; NAC; Vitamin C from 1950 to 2021 till date. We found a total of 6500 articles out of which we selected 110 articles for this review. No meta-analysis was done. Thus here we detail the different sources of ROS, at the tie of sepsis, besides their pathophysiological crosstalk with the immune system, microcirculation as well as mitochondria that can result in the generation of AKI. Furthermore, we detail the therapeutic utility of N-acetylcysteine (NAC), besides the reasons for its success in ovine as well as porcine models of AKI. Moreover, we discuss preclinical along with clinical for evaluation of Vitamin C’s antioxidant effects as well as pleiotropic effects as a stress hormone that might aid in abrogation of septic AKI.

Background: Currently there are three available formulations of tacrolimus in the United States; these include immediate-release capsules (TAC-IR), extended-release capsules (TAC-XL),and extended-release tablets (TAC-XR). Previous studies have demonstrated non-inferiority between the three formulations in terms of efficacy. The purpose of this study was to compare three formulations of tacrolimus (TAC) and assess differences in time within the therapeutic range (TTR) and variability in levels. Results: Renal transplant recipients from January 2013 to October 2017 were retrospectively identified for analysis. Deviation from standard TAC protocol or formulation changes excluded patients. The primary outcome compared percent TTR (TTR %) among 3 TAC formulations over the first 90 days post-transplant. TTR was calculated using the Rosendaal method. Secondary outcomes included differences in TAC levels, TAC dose, eGFR, rejection, patient and graft survival between the TAC formulations. TAC-XR demonstrated a significantly higher TTR % compared to TAC-IR and TAC-XL (62.8% vs. 53.3% vs. 60.9%, p = 0.048). In post-hoc analysis, TAC-XR had a higher TTR % compared to TAC-IR (p = 0.065), which approached statistical significance. Average TAC levels, weight-normalized TAC doses, median dose-normalized TAC levels, rejection rates, eGFR, and graft or patient survival were similar among groups. Conclusion: In the early transplant period, TTR was significantly different among the groups. TAC-XR demonstrated numerically superior time within the therapeutic range. Patient-specific factors such as race, obesity, genetic polymorphisms may impact this variability and clinical outcomes. Further analysis is necessary to understand the effect of each patient-specific factor on TAC exposure.

Introduction: Modern pediatrics of disasters is built on 5 basic principles: integrity, structure, causality, dynamism, and hierarchy.Material and methods: Methodological approaches were used: systemic, complex, integration, functional, dynamic, process, normative, quantitative, administrative, and situational, and methods: historical, analytical, and comparison. Techniques were used: grouping, absolute and relative values, detailing, and generalization.Results: The algorithms of actions of the doctor of the children’s clinic in the event of a fire, the receipt of a call about the laying of explosives and the threat of explosion were considered, the scope of the provision of first qualified aid to the pediatric nursing team was clarified. The issues of the organization of the first qualified and specialized medical care, taking into account the anatomical and physiological characteristics of children and adolescents, as well as medical tactics for small-medium, and large disasters in rural areas and cities are discussed.Conclusion: Pediatrics of disasters is an independent section of organizational and medical work in emergencies and terrorist acts, providing specialized medical care for at least 25% of victims, who are children and adolescents. The training of doctors of a specialized children’s polyclinic is regulated by regulatory documents of the Russian Federation and the Republic of Komi, Orders of the Ministry of Health of the region, a municipal formation, and a medical institution in the field of civil defense and emergency situations. In case of minor emergencies and disasters within the city boundaries with the occurrence of a single or a small number of group losses, medical support repeats that in road traffic accidents, with the exception of the organization and conduct of medical triage. In rural areas, it is required to attract additional medical and nursing teams (emergency medical aid teams), created on the basis of medical institutions of the victim and neighboring areas. At the same time, a forced maneuver by the forces and means of territorial health care is necessary for the medical evacuation of a significant part of the affected children to specialized institutions (departments) located in cities. The provision of psychological and psychiatric assistance to children and adolescents in emergencies is carried out on the basis of its basic modules (departments and offices of psychological and psychiatric assistance, and advisory mobile team of psychological and psychiatric assistance, anonymous psychological and psychiatric assistance by telephone).

Introduction: Preparing a report and passing certification for a qualification category is one of the forms of improving the professional level of each medical worker.Material and methods: The analysis of 5 qualification works of a psychiatrist (1997, 2002, 2008, 2013, and 2018) was carried out for the mandatory requirements for the preparation of documents when they were submitted to the Attestation Commission on the assignment of a qualifying medical category in psychiatry and formation methodological approaches to their implementation. The depth of research was 27 years.Results: Methodological approaches to the design of 11 mandatory sections provided for in the certification work of a psychiatrist presented for the award of a qualification category were considered.Discussion: The attitude to the Administrative Regulations for the provision of state services for the assignment of a qualification category to specialists engaged in medical and pharmaceutical activities should be revised in terms of its synchronization with the official duties of a doctor.Conclusion: The dynamic development of the regulatory, organizational, methodological, and scientific aspects of medicine and psychiatry, in particular, in the period of active digitalization of healthcare, requires periodic corporate discussion and correction of the Administrative Regulations for the provision of public services for assigning a qualification category to specialists engaged in medical and pharmaceutical activities.Attention should be paid to the insufficient statistical processing of the submitted materials by applicants for the assignment of the 1st and highest categories, the lack of calculations, references, and comparisons of confidence intervals, and the reliability of the study.Preparing a report and passing certification for a qualification category can be the first step in introducing a practitioner to scientific work through the generalization of personal work experience, worthy of speaking at a scientific and practical conference at the level of LU and the region and publishing abstracts in collections and scientific and practical journals.The proposed methodological approaches are purely advisory in nature and can be used by psychiatrists when working on a qualification category at their discretion.

In this work, α-induced 59Co reactions in the energy range from 11- 41MeV were used in order to study the role of pre-equilibrium emission. The experimentally measured excitation functions for residues populated via (α, n),(α, 2n),(α,3n),(α,2p),(α, 3n 2p) and (α, 4n 2p) channels in the interaction of  + 59Co system available in the literature [13] were compared with theoretical predictions obtained using the statistical model code COMPLET. It was observed that at higher energy points the pure compound nucleus predictions, in general, failed to reproduce the measured data at projectile energies ~11-41MeV, this shows significant contributions from pre-equilibrium emission. The study signified both equilibrium and pre-equilibrium emissions were required to reproduce the presently measured excitation functions. An attempt was made to deduce the contribution coming from pre-equilibrium emission. It was found that the pre-equilibrium contribution increases with increasing projectile energy. Furthermore, the present result revealed a strong correlation between pre-equilibrium contribution and particle multiplicity.

Stems of Santalum album (Sandalwood), Mangiferra indica (Mango wood), and Tinospora cordifolia (Giloy) are widely used in the preparation of herbal medicines and formulations in the traditional Indian health care system called Ayurveda. These were analyzed for 4 minor (K, Ca, Cl, Mg) and 13 traces (As, Ce, Co, Cr, Cu, Fe, Hg, La, Mn, Na, Se, V, and Zn) including toxic elements by instrumental neutron activation analysis (INAA). Samples in powder form along with reference materials (NIST SRM 1547 and INCT MPH-2) as comparators were irradiated for 1 min/6 h in Dhruva/CIRUS reactors at BARC, Mumbai. Gamma activity was measured by high-resolution gamma-ray spectrometry. In general, K, Ca, Fe, Mn, and Zn contents are very high in all the samples but Santalum album, widely used as a perfume, is more enriched in K, Ca, Cr, Zn, and Se. The concentration of Ca is always high as a major constituent (> 10 mg/g) in all the stem/bark of plant species. A strong inverse correlation (R2 = 0.9999) was observed between Fe and Zn in all three samples and that may be useful in drug manufacturing.

Aim: Accumulating data imply that glaucoma may represent a neurodegenerative disorder affecting the entire visual system. We evaluated retrobulbar glaucomatous damage with favorable techniques for 1.5T diffusion-tensor magnetic resonance imaging and we compared those techniques with clinical data in a large case series. Material and methods: This Cross-sectional study included 130 eyes of 65 patients with primary open-angle glaucoma. Patients with no known ocular or systemic concomitant disorders, neurological diseases, previous glaucoma surgeries, or antioxidant usage were selected. A decrease in thickness and deterioration in the optic nerve diffusion of severely glaucomatous eyes of patients with asymmetrical involvement was observed in optic nerve tractography. Optical coherence tomography and visual field results of the subjects were recorded. Glaucoma analysis with optical coherence tomography and standard automated perimetry results of the subjects were recorded. Diffusion-tensor magnetic resonance imaging analysis of optic nerves and radiations were performed, computing fractional anisotropy, apparent diffusion coefficient, axial diffusivity, and radial diffusivity. Correlation between the diffusion-tensor magnetic resonance imaging and clinical eye parameters of glaucomatous neurodegeneration were statistically evaluated. Results: The correlations between diffusion parameters and age were highly significant. Statistically significant correlations were found between ganglion cell complex and apparent diffusion coefficient, axial and radial diffusivities of optic nerves. Conclusion: Eye-brain connection in glaucoma can be evaluated with routine clinical instruments. Our study also revealed a limited correlation of retrobulbar glaucomatous neurodegeneration with ophthalmic damage. A better understanding of retrobulbar damage will enable us to develop more efficient strategies and a more accurate understanding of glaucoma.

Background: An association between Atrial Fibrillation (AF) and Metabolic Syndrome (MS) a constellation of abnormalities (high blood pressure, hyperglycemia, dyslipidemia, and abdominal obesity), has been demonstrated. There have been many studies that have shown that elevated blood pressure (BP), was significantly associated with an increased risk of AF. It is uncertain whether maintaining the optimal BP levels can prevent AF in the patients with MS categorized as ‘high-risk’ patients.Objective: The aim of this study was to evaluate the influence of control of BP on the occurrence of new-onset atrial fibrillation in patients with Metabolic Syndrome.Methods: Into this observational study, was enrolled 435 consecutive patients (210 males and 225 females) aged 45-79 years who fulfilled criteria for MS. Participants were selected among primary and secondary care patients, who were receiving ongoing care for arterial hypertension in the period from November 2018 till November 2021. The study was conducted at outpatients in 5 Health Care Clinics (3 Secondary Health Care Clinics and 2 Primary Health Clinics). Patient were categorized according to their BP levels as Group 1-patients with controlled BP, {(patients aged < 65 years Systolic Blood Pressure (SBP) of 120 - 130 mmHg, patients aged ≥ 65 years SBP of 130 - 139 mmHg)} and Diastolic Blood Pressure (DBP), {(patients aged < 65 years of < 80 mmHg. but not < 70 mmHg; patients aged ≥ 65 years of 85 - 89 mmHg)}, or Group 2-patients with uncontrolled BP(> 130/80 mmHg),and in patients aged ≥ 65 years BP (≥ 140/90 mmHg ). Results: New-onset of AF, was more frequent in participants with uncontrolled BP, respectively (34.7% vs. 19.5%, p = 0.009).Patients with uncontrolled BP have more frequent persistent AF (15.2% vs. 0.04%) and permanent AF (0.08% vs. 0.02%), whereas there was not significant changes between groups in relation to frequency of paroxysmal AF, respectively (12.8% vs. 10.9%, p = 0.29). There was observed significant association of uncontrolled BP with: increased frequency of AF (OR = 2.193; 95% CI 1.390 - 3.439), persistent AF (OR = 3.931; 95% CI 1.771 - 8.084), permanent AF (OR = 4.138; 95% CI 1.383-12.381), LA. Dimension ≥ 2.2 cm/m2 (OR = 2.089, 95% CI 1.330 - 3.252), BMI (OR = 5.226, 95% CI 3.155 - 8.659) and 5-risk factors for MS, respectively (OR = 2.998, 95% CI 1.833 - 4.901).Conclusion: Optimal BP levels, can reduce the frequency of new-onset AF in patients with MS categorized as ‘high-risk’ patients. Uncontrolled BP was associated with an increased risk of both subtypes of AF (persistent and permanent) in the patients with MS categorized as ‘high-risk’ patients.

Background: Many institutional factors predispose University students to mental health issues, including depression. However, with no central database for depression in Uganda, literature on depression and associated institutional factors among undergraduate students is scarce. This study examined the prevalence of and institutional factors associated with depression among undergraduate students at Gulu University.Methods: This was a cross-sectional survey among 452 undergraduate students at Gulu University in the academic year 2018/2019 in February and March 2019. A stratified simple random sampling was used to identify the participants. A self-administered questionnaire was used to collect data. Descriptive statistics, including mean and frequency, were used. We conducted a bivariate analysis to determine the association between variables employing Pearson’s chi-square test or Fischer’s exact test. We conducted a multivariate analysis with factors that had significant P-values of less than 0.05.Results: The average age of the respondents was 22.4 (SD - 2.4), more than half (53.1%) were male and 38.50% were in the second year. The results show that 31.19% reported depression. After controlling for age and sex, the results showed that there was a statistically significant correlation between depression and faculty (aOR - 1.15), year of study (aOR - 0.77), happiness with the course (aOR - 0-0.49), satisfaction with academic performance (aOR - 0.45), and satisfaction with academic quality (aOR - 0.61). The results indicated that the predictors of depression among undergraduate students were faculty, year of study, satisfaction with academic performance, and satisfaction with academic quality. Conclusion: A substantial proportion of Gulu University undergraduate students reported high levels of depression. The results, therefore, showed that depression in undergraduate students is an identifiable disorder that needs diagnosis, prevention, and treatment. Faculty, year of study, satisfaction with academic performance, satisfaction with academic quality were predictors of depression. Thus there is an urgent need for counseling, psychoeducation, and preventive mental health services as an essential part of the university setup.

Objective: To report our experience in the management of gastric cancers at the Kara University Hospital (Togo).Materials and methods: This was a retrospective and prospective study which was conducted from January 1, 2018, to July 31, 2021, in the general surgery and hepato-gastroenterology department of the Kara University Hospital (Togo). This study involved all patients treated for gastric cancer during the study period at CHU Kara (Togo).Results: We recorded 32 gastric cancers out of the 218 cases of cancer diagnosed during the study period. We had 20 men and 12 women with a sex ratio (M/F = 1.7). The average age was 58 years with the extremes ranging from 17 to 85 years. The pattern of the consultation was dominated by epigastralgia (100%) and deterioration in general condition (100%). Upper digestive endoscopy with biopsies was performed in all our patients. The antral localization was the most found in 62.5% of cases. The most common macroscopic appearance was ulcers-budding (90.6%) and the dominant histological type was moderately differentiated adenocarcinoma (87.5%). The extension assessment found liver metastasis in 10 cases, multiple regional lymphadenopathies of the hepatic pedicle and celiac trunk in 26 cases, ascites related to peritoneal carcinomatosis in 26 cases. Therapeutically, a 4/5 gastrectomy with D1 dissection was performed in 6 cases; gastrojejunal anastomosis in one case and palliative treatment in 25 cases. Survival at 1 year is 50% (3 patients) among operated patients. All the other patients (78.1%) who received palliative treatment all died within 3 months.Conclusion: Improving the prognosis of stomach cancer like other cancers requires early diagnosis to perform a gastrectomy, the only guarantee of long survival.

Environmental and behavioral factors are very important for exposure to airborne SARS-CoV-2. Indoor environments are related to infection events, including super-spreader events and outbreaks. Indoor, poorly ventilated, and crowded areas, such as restaurants, cinemas, and bars can be effective in the accumulation of aerosols full of viruses, especially if people are in conversations and stay there for a long time period. At longer distances (more than 1.5 meters), small aerosols that can stay in the air for a longer period of time are dominant. The super-spreader events in which people have been infected at a distance away show that this remote transmission occurs. The exposure risk to longer intervals is likely to be more in domestic environments and indoor spaces that lack sufficient ventilation. Layer interventions are of fundamental importance. Therefore, it is important to take preventive measures as much as possible and follow them as carefully as possible, because no intervention alone will be effective in eliminating the risk. These include spacing, lining, hand hygiene, filtration, and ventilation.

In the present study, omental adipose tissue was collected from, the animals that underwent ovariectomy and ovariohysterectomy, surgical procedures, at the age of seven months to 11/2 years of age groups. The sample was digested with 0.1% (W/V) collagenase type I and transferred to a beaker with a magnetic stirrer and kept in a stirrer with 600 rpm at 37 °C for 30 minutes. The viability of the cell was evaluated by the trypan blue exclusion method using a hemocytometer. Trypan blue had a high affinity to nuclear DNA, which traverse the member in a dead cell and dye it blue. In the present study, the cell yield of fAD-MSCs was 8.15 ± 0.68, 6.55 ± 0.26, 4.85 ± 0.42, 3.90 ± 0.34, and 3.51 ± 0.43 in different age groups viz., 7,8,9 month 1 and 1½ year respectively. In younger age groups, cell yield and viability percentage were more than in animals of higher age groups. In the younger age group, stem cells proliferation status is considered potent for therapeutic application.

Plant-parasitic nematodes (PPNs) are famous aggressive pests that attack several crops worldwide. A lot of farmers are suffering from nematode diseases which cause critical crop losses. At the same time, the most of available solutions for this problem are depending on synthetic nematicides. These chemical nematicides not only cause environmental and health problems but also may cause resistance in nematodes. Despite the occurrence of resistance in nematodes under field conditions still less clear. Therefore, this note is about the registered nematicides in Egypt which may help those who are interested in nematicides. Also, the chemical group and mode of action of nematicides were mentioned according to the insecticide resistance action committee (IRAC) [1] and fungicide resistance action committee (FRAC).

Background: Cerebral visual impairment (CVI) is a bilateral visual impairment that affects children in all industrialized countries. It has become more common in low-income countries as a result of the increased survival rates of children who suffer from severe neurological conditions during the perinatal period. The purpose of this study was to determine the characteristics of children with CVI in a tertiary children’s eye care center population.Methods: From October 2020 to September 2021, a cross-sectional study was conducted to select all consecutive patients with a diagnosis of cerebral visual impairment aged 6 months to 16 years. On the neurological deficit, information was gathered from the patient’s referral: parental interviews, observations, and direct assessment were used for functional vision characteristics, and an ophthalmic examination was performed for eye findings. The interviewees’ responses were matched to the ten specific behavioral characteristics shared by children with CVI. Cortical visual impairment was diagnosed using three criteria: [the vision loss is not explained by abnormalities found on the eye examination, a neurological medical diagnosis, and the child exhibits one of the unique visual and behavioral characteristics described by Roman Lantz]. A descriptive statistical analysis (frequency, mean, and range) was calculated. Results: Forty children with CVI (1.96% of total children) were seen. The mean age was 2.56 ( 1.98) years. There were 24 (60%) males. On a referral paper of 28, hypoxic-ischemic encephalopathy was the commonest cause mentioned (70.0%). Seizures were the most frequent neurological deficit at presentation. Ophthalmic and neurologic impairments were found in 42.5% of children with CVI. Based on Roman-Lantzy’s three phases of the CVI Range, 90% of children with CVI at the test time had Phase I or Phase II vision.Conclusion: According to the findings of this study, visual impairment is critical in the diagnosis of CVI. The prevalence of CVI as a cause of childhood vision impairment is significant. Hypoxic-ischemic encephalopathy is the most common cause of CVI. All children with CVI have serious neurological issues, and the majority have associated ophthalmic abnormalities.

Endotheliosis, thrombotic microangiopathy and complement system over activation have been described as pathologic features of tissue damage in the setting of coronavirus disease. Interestingly, complement-mediated cell injury is also a typical feature of atypical Hemolytic Uremic Syndrome. Indeed, a growing body of literature has described a higher risk of microangiopathy recurrence, in aHUS patients who test positive for SARS-CoV-2. The correct clinical and therapeutic management patients with a history of HUS and SARS-CoV-2 infection is not well established.We report a case of SARS-CoV-2 infection in an aHUS patient who did not develop a recurrence of the disease and that was successfully treated with convalescent immune plasma therapy.

The effect of the novel coronavirus (SARS-CoV-2) pandemic has produced significant health concerns negatively impacting individuals. As the ongoing and constantly changing nature of SARS-CoV-2 continues, the unique characteristics of this pandemic trend toward anxiety and loneliness as significant behavioral health outcomes. Furthermore, the SARS-CoV-2 pandemic has significantly impacted the utilization of social media platforms such as Twitter. Utilizing over 1.6 million tweets from approximately 988,760 Twitter users geolocated in Washington state from the University of Pennsylvania’s publicly available Twitter database (from March 2020 to March 2021), this study evaluated the impact of SARS-CoV-2 by using expressions of loneliness and anxiety to predict mental and physical symptoms. Bivariate correlations revealed expressions of loneliness were correlated to trouble breathing while expressions of anxiety were correlated to skin lesions, body aches, flu-like, seasonal cold, trouble breathing, nausea or diarrhea, fever, chills, and cough. Multiple multivariate linear regressions were completed, and a significant regression equation was found in predicting trouble breathing symptoms on expressions of loneliness and anxiety, however, the proportion of variance was 8% of the observed variation in the model. Further implications revealed the importance of understanding mental and physical well-being during a public health crisis as well as the use of social media platforms as primary and supplementary stimuli.
