Clinical Risk Factors Associated With Late-Onset Invasive Group B Streptococcal Disease: Systematic Review and Meta-Analyses

Abstract Background Group B streptococcal (GBS) infection remains one of the most significant causes of late-onset sepsis and meningitis (LOGBS) among young infants. However, transmission routes and risk factors for LOGBS are not yet fully understood. Methods We conducted systematic reviews on clinical risk factors previously reported in the literature (prematurity, low birth weight [<2500 g], antenatal colonization, multiple-gestation pregnancy, maternal age <20 years, male infant sex, intrapartum fever, prolonged rupture of membranes) and meta-analyses to determine pooled estimates of risk. Results We included 27 articles, reporting 5315 cases. Prematurity (odds ratio [OR] 5.66; 95% confidence interval [CI]: 4.43–7.22), low birth weight (OR 6.73; 95% CI: 4.68–9.67), maternal colonization (2.67; [2.07–3.45]), and multiple-gestation pregnancies (OR 8.01; 95% CI: 5.19–12.38) were associated with an increased risk of LOGBS. Conclusions Prematurity/low birth weight and maternal colonization are major risk factors for LOGBS. Future GBS vaccine studies should try to establish the optimal time for vaccination during pregnancy to protect preterm infants.
ENHANCEMENT OF GUAR GROWTH AND PRODUCTIVITY BY BradyrhizobiumINOCULATION UNDER DIFFERENT NPK FERTILIZATION LEVELS

Two field experiments were carried out during the two consecutive summer seasons of 2019 and 2020 at Experimental Farm (Ghazala Farm) of Agric. Fac. , Zagazig Univ., Egypt. This study was to try to enhance the growth and yield of guar plant. The experiment was set up as split-plot design between NPK fertilization as main plot and bio-fertilization as sub-plot. The NPK fertilization levels were (0.0, 75, 100 and 125% of recommended level), while, the Bradyrhizobium inoculation rates were (0.0, 200 and 400 g/feddan). The NPK fertilization recommended rate (RR) was Ammonium sulfate (20.5% N) at 200 kg/feddan, calcium super phosphate (15.5% P2O5) at 200 kg/feddan and potassium sulfate (48% K2O) at 100 kg/feddan. The obtained results revealed that fertilized guar plants with 125% RR significantly increased plant growth (plant height, number of leaves and branches/ plant, fresh and dry weights of branches, leaves and roots/plant and root length), yield components (pods number per plant and seed yield per plant and per feddan) as well as total carbohydrates content compared to control and the other levels under study. Moreover, the highest Bradyrhizobium inoculation rate (400 g/feddan) significantly recorded the highest values of all abovementioned parameters compared to control and lowest one. Predominantly, the results of this study showed that fertilized guar plants with 125% RR of NPK fertilization could help to enhance growth and productivity of guar (Cyamopsis tetragolnoloba Taub.) plant combined with 400 g/feddan of Bradyrhizobium inoculation rate under Sharkia Governorate conditions.
Analysis of Citrus Tristeza Virus Incidences within Asian Citrus Psyllid (Diaphorina citri) Populations in Florida via High-Throughput Sequencing

Simple Summary The iconic citrus crop of Florida is suffering from an incurable disease called Huanglongbing (HLB), or citrus greening. HLB is caused by a bacterium Candidatus Liberibacter asiaticus (CLas), which is efficiently vectored by a small insect, the Asian citrus psyllid (ACP). To control the spread of CLas and ultimately HLB, citrus growers primarily depend on environmentally harmful insecticides against the ACP, which can induce insecticide resistance. An alternative, biological approach involves insect-specific viruses (ISVs) of the ACP for future exploitation to exclusively target this insect pest. To identify these ISVs, we have subjected ACPs to high-throughput sequencing, a powerful sequencing technology. This current study follows an initial detection of citrus tristeza virus (CTV) amongst the viruses detected in the ACP during HTS and continues to show the persistent and diverse presence of CTV in Florida ACPs across subsequent years. We suggest that the ACP may be utilized as a tool or lens of CTV presence throughout Florida citrus groves. Abstract The destructive citrus disease, Huanglongbing (HLB) or citrus greening, continues to devastate Florida’s citrus industry. A hemipteran insect, the Asian citrus psyllid (ACP), disperses Candidatus Liberibacter asiaticus, one of the putative bacterial pathogens of HLB. This study builds upon ongoing research utilizing high-throughput sequencing to analyze the virome of ACP populations collected from citrus groves throughout Florida. Following the widespread detection of sequences aligning to the genome of citrus tristeza virus (CTV) across consecutive years in the Florida ACP virome, we continued to detect a pervasive amount of CTV in Florida ACPs during subsequent years. Simultaneously, we also detected mixed infections of CTV strains in pooled ACPs from different Florida regions. Predating the HLB epidemic, CTV has been present in Florida for many years and our results confirm its widespread and diverse persistence in Florida citrus groves through a unique lens, the ACP. CTV presence in the ACP likely results from feeding on CTV-infected citrus trees in Florida citrus groves, which may help to understand an overlapping presence of CTV and HLB, both endemic citrus pathosystems in the state, and their role in future integrated pest management strategies.
Comparing IgG Binding to Megakaryocytes in Thrombocytopenic Patients

Background and objectives: The aim of the present study is to evaluate and compare IgG-binding to megakaryocytes in bone marrow of ITP and MDS patients to determine megakaryocytes targeting by autoantibodies in vivo as a mechanism of platelet underproduction in these disorders. Subjects and methods: The study was carried out on 20 ITP (group I) patients and 20 thrombocytopenic patients with myelodysplastic syndrome (group II) who were admitted to minia university hospital. Serial histological sections from bone marrow biopsies were stained for IgG. Results: high IgG binding was found in ITP and MDS patients (group I & II ) and there was no statistically significant difference between both groups ((14/20 (70%) vs. 13/20 (65%),), (P value =0.736). Conclusion: Antibody binding to megakaryocytes in a proportion of MDS patients suggests that immune mediated mechanism underlies PLT underproduction in those patients
Effect of Emdogain and Diode laser Irradiation ‎on ‎Periodontal Healing of Replanted Teeth after ‎Extended Extra ‎‎- Oral Dry time ( An Experimental ‎Study).‎

Dental injuries usually affect one or two of the anterior teeth, and especially the maxillary central incisors. The aim of the experimental study was to radiographically evaluate the effect of both Emdogain with and without high power Diode laser irradiation Emdogain with and without high power Diode laser irradiation on replanted teeth of rats teeth of rats after extended extra oral dry time. Material and methods: The study was conducted on extracted maxillary incisors of 42 adult male Albino rats weighing 160–250 g. The rats were assigned to three groups 14 rats in each, then replanted after 75 minutes as follow ; Group I (Control group) no treatment for the root surface was performed on the extracted upper right central incisors and alveolar wound before their replantation. Group II (EMD) Emdogain was applied on root surface and alveolar wound. Group III Diode laser then Emdogain were applied on root surface and alveolar wound. Replantation was done then splinting of teeth. Half of each group was euthanized after 4 weeks, while the other half after 8 weeks. The jaws were dissected out for radiographic examination using standardized periapical technique. Results: The radiographic analysis showed that the alveolar crest bone density in group III was the highest and less in the group II, while the least density was in the group I. Conclusion : Application of EMD to the root surface has limited inductive effects on bone while using EMD with Diode laser leads to better PDL healing and formation of bone in comparison to using EMD only or without treatment of root surface.
Neural Network Aided Digital Self-Interference Cancellation for Full-Duplex Communication Over Time-Varying Channels

In-band full duplex communication requires precise self-interference cancellation (SIC) to successfully decode the received desired signal. The existing neural network (NN) based SIC scheme uses offline trained NN to estimate the non-linear component of received self-interference (SI) over a static SI channel without additional NN training. For the time-varying SI channel, the NN-aided SIC method needs to retrain the NN during in-band full duplex communication to adapt time-varying channels. However, NN training is not fast enough to be done during full duplex communication. Thus, the SIC performance degrades. In this paper, we propose a digital SIC scheme using channel robust NN which takes estimates of linear SI channel coefficients as an input. It was found that the NN could learn the static part of the non-linear behavior of the SI channel well. Our solution can adapt the time-varying SI channel with only the channel coefficient estimation of linear components and a pre-trained NN. The proposed scheme can successfully reduce the SI to the noise floor for both time-invariant and time-varying SI channels.
Treatment of Slipped Capital Femoral Epiphysis with a Modified Dunn Procedure

Background: Moderate to severe slipped capital femoral epiphysis leads to premature osteoarthritis resulting from femoroacetabular impingement. Modified dunn procedure restore the normal anatomy, complete correction of the slip angle, and minimize the probability of cam-type FAI with preservation of physeal blood supply. Patients, Methods: A prospective study was conducted on 15 patients with moderate and severs SCFE were treated with modified dunn procedure during the period from March 2017 to February 2020 , 12 males (80%) and 3 females (20%) with mean age was 15.2 years at the date of surgery The Right hip was affected in 9 patients (60%) and the left hip in 6 patients (40%). 10 cases were stable, while 5 cases were unstable. The mean follow up period was 15.1 month. Results: Postoperatively, the harris hip score (HHS) ranged from 60 to 100 with mean value 93.7 (SD was 13), WOMAC score ranged from 0 to 20 with mean value 3.7 (SD was 5.5) and the Heyman and Herndon score was excellent-good in 13 cases (86.7%),and poor in two cases (13.3%). Radiologically, all parameters showed significant improvement with the mean slip angle corrected from 53.9 0 (SD 11.7) preoperatively to 5.1 0 (SD 5.7) postoperatively, the mean alpha angle corrected from 100 0 (SD 14.1) preoperatively to 51.9 (SD 5.3) postoperatively. AVN and implant removal occurred in only two cases (13.3%). Conclusion: Capital realignment through the modified dunn procedure is an effective and safe treatment option for moderate and severe SCFE in patients with open physes as it allows anatomical restoration of hip anatomy thus preventing FAI with its sequalae and and provide good short-term outcome with low complication rate.
Continuous genomic diversification of long polynucleotide fragments drives the emergence of new SARS-CoV-2 variants of concern

Abstract Highly transmissible or immuno-evasive SARS-CoV-2 variants have intermittently emerged, resulting in repeated COVID-19 surges. With over 6 million SARS-CoV-2 genomes sequenced, there is unprecedented data to decipher the evolution of fitter SARS-CoV-2 variants. Much attention has been directed to studying the functional importance of specific mutations in the Spike protein, but there is limited knowledge of genomic signatures shared by dominant variants. Here, we introduce a method to quantify the genome-wide distinctiveness of polynucleotide fragments (3- to 240-mers) that constitute SARS-CoV-2 sequences. Compared to standard phylogenetic metrics and mutational load, the new metric provides improved separation between Variants of Concern (VOCs; Reference = 89, IQR: 65–108; Alpha = 166, IQR: 149–181; Beta 131, IQR: 114–149; Gamma = 164, IQR: 150–178; Delta = 235, IQR: 217–255; and Omicron = 459, IQR: 395–521). Omicron's high genomic distinctiveness may confer an advantage over prior VOCs and the recently emerged and highly mutated B.1. 640.2 (IHU) lineage. Evaluation of 883 lineages highlights that genomic distinctiveness has increased over time (R2 = 0.37) and that VOCs score significantly higher than contemporary non-VOC lineages, with Omicron among the most distinctive lineages observed. This study demonstrates the value of characterizing SARS-CoV-2 variants by genome-wide polynucleotide distinctiveness and emphasizes the need to go beyond a narrow set of mutations at known sites on the Spike protein. The consistently higher distinctiveness of each emerging VOC compared to prior VOCs suggests that monitoring of genomic distinctiveness would facilitate rapid assessment of viral fitness.
New Findings Relating Tidal Variability and Solar Activity in the Low Latitude MLT Region

Mesospheric winds have been measured by meteor radar at Cachoeira Paulista (22.7°S; 45°W) since April 1999. The tidal components were analyzed over about 21 years of available data exhibiting an annual and semi‐annual variation. Amplitudes of meridional diurnal (semidiurnal) tide are on averaged 30% (28%) and the zonal ones are 14% (20%) stronger at solar minimum than at solar maximum. The anticorrelation between F10.7 cm solar flux and amplitudes of the semiannual oscillation of diurnal and semidiurnal tides is presented. Additionally, the sporadic E (Es) layers occurrence has an anti‐correlation with solar activity due to the tidal wind variation. A discussion about the physical mechanism is performed in terms of the particle precipitation during High‐Speed Stream (HSS) events according to the solar cycle. Finally, a superposed epoch analysis of the tidal amplitudes during the HSS events in 2018 is presented. And a slight increase in all tidal components is seen when the structure reached the Earth and in the following days showing that indeed the electron precipitation during HSS events affect the tidal amplitudes.

Relationship Between Source and Sinke in some Different Durum Wheat Cultivars

Source and sink relationship determine the growth and development in cereals, and can serve as reliable indicator to estimate durum wheat yield. A multi-year field trial was executed on ICARDA farm, Sids Agricultural Research Station farm, Agricultural Research Center (ARC), Egypt, during the two successive growing seasons of 2018/2019 and 2019/2020 to determine the effect of defoliation (source and sink limitation) on the yield attributes and grain yield of eight durum wheat cultivars. Eight defoliation treatments viz., i) control (no defoliation), ii) flag leaf blade removed, iii) flag leaf blade and the secondary leaf removed, iv) secondary leaf removed, v) spike awns and secondary leaf removed, vi) spike awns and flag leaf blade removed, VII) spike awns removed, and viii) Spike awns, flag leaf blade and secondary leaf removed were applied on eight durum wheat cultivars viz. i) Bani Suef 1, ii) Bani Suef 3, iii) Bani Suef 4, iv) Bani Suef 5, v) Bani Suef 6, vi) Sohag 3, vii) Sohag 4 and viii) Sohag 5. The study was comprised of wheat cultivars as the main plot while, defoliation (source and sink limitation) treatments as the sub-plots. Cultivars and treatments had significant effect on the number of grains spike-1, 1000-grain weight and grain yield. However, the highest grain yield was obtained from ‘Bani-suef-1under all wheat defoliation treatment. On the other hand, the removal of spike awns and the secondary leaf treatment produced the highest 1000-grain weight and grain yield.
Internal Customers’ Perception of the Relationship between CSR & their Commitment and Turnover Intention

This study aims to identify the impact of internal customer’s (i.e employees) corporate social responsibility (CSR) perception on their affective commitment and turnover intention and the moderating effect of self-concept on these relationships. The study is applied on bank employees in Egypt. A quantitative study where 199 valid survey-based questionnaires were collected was adopted for this study. The questionnaires were collected through non-probability sampling from bank employees on social networking sites. The study reveals that internal customer’s CSR perception impacts their affective commitment and turnover intentions. Philanthropic CSR has the highest positive significant impact on affective commitment while Legal CSR has the highest negative significant impact on turnover intentions. Moreover, affective commitment had a negative significant effect on turnover intentions. Finally, self-concept did not show a significant moderating effect on the relationship between CSR and affective commitment and turnover intentions.
Related factors to aging-career interest: ageism and self-efficacy in the context of a life-span development course

ABSTRACT The rising number of older adults increases the need for more workers willing and capable of working with the aging population. However, ageism presents a challenging barrier to overcome. This study aimed to determine the relationship between ageism, self-efficacy, and career interest across a semester; the impact of participating in aging-related experiences with older adults was also examined. College students (N = 182) enrolled in a life-span development course had the possibility of engaging in age-related experiences for course credit; out of class aging-related experience was also cataloged. This resulted in four groups: no experience (n = 73); developmental course experience only (n = 40); other age-related experience only (n = 45); and both developmental and other age-related experience (n = 23). Data were collected at the beginning and end of the semester to assess interest in aging-related careers, perceived self-efficacy in working with older adults, and benevolent and hostile ageism. Results revealed that low levels of ageism and high levels of self-efficacy predicted aging-related career interest at the end of the semester. However, there was not a significant interaction between time and aging-related experience, although those with both in and out of class aging-related experience reported significantly higher aging-related career interest. These findings suggest that ageism and self-efficacy should be a focus when trying to increase interest in aging-related careers, but not all aging-related experience is capable of shifting these variables. Course context may matter.
Neglect, Abuse, and Adaptive Functioning: Food Security and Housing Stability as Protective Factors for Adolescents

This study addresses gaps in knowledge of protective factors that support adaptive functioning among maltreated adolescents. The sample included 1003 high-risk youths participating in the Longitudinal Studies of Child Abuse and Neglect (53% female, 56% Black, and 82% living in poverty). Adolescent neglect (Exposure to Risky Situations, Lack of Monitoring, Inattention to Basic Needs, Permitting Misbehavior, Lack of Support) and physical, sexual, and emotional abuse were self-reported at age 16. Age 18 adaptive functioning measures included healthcare receipt (medical, dental, and mental health), self-rated global health, high school graduation or enrollment, prosocial activities, peer relationships (Companionship, Conflict, Satisfaction, and Intimacy), and independent living skills. Previous childhood maltreatment, demographics, and earlier prosocial activities and peer relationships were controls. Structural equation modeling showed that adolescent neglect and abuse were associated with lower adaptive functioning. Multigroup models showed protective effects for food security on the relationships between sexual abuse and self-rated health and between Inadequate Monitoring and Companionship. Housing stability buffered relationships between Inadequate Support and high school graduation or enrollment and between Permitting Misbehavior and independent living skills. Findings imply the need for adolescent-focused prevention, including the promotion of food security and housing stability to support adaptive functioning in maltreated adolescents. However, notable mixed findings show the need for additional research.
Effect of Planting and Harvesting Dates on the Physiological Characteristics of Cotton-Seed Quality

Cotton is grown intentionally for fiber and oil, so that cotton-seed quality has economic importance for its products quality. Data about cotton-seed quality is limited. Experimental carried out during 2020-2021 seasons at Mallawi Research Station, Plant Physiology Department, Cotton Research Institute, Agricultural Research Center, Egypt, using Giza-95 variety to evaluate planting date effect and picking time on cotton-seed quality properties (seed volume, seed density, immaturity, inhibition rate%, germination rate%, cleanness%, impurities% and agricultural values), cotton-seed chemical contents (oil%, protein%, nitrogen%, carbohydrates% and moisture%), yield and its components (opened number boll/plant, boll weight, seed index, lint% and yield/k/f) and fiber quality properties (fiber length, uniformity index, micronaire reading and fiber strength). Experimental was split-plot design by three replications, main plots were planting date (early and late) and subplots were picking time (first and second). Results revealed that, early planting and picking time effected significantly on cotton-seed quality properties, cotton-seed chemical contents, yield, its components, and fiber quality properties in tested-seasons, which early planting date treatment with first picking gave best values in tested-seasons compared to other treatments that relative to allow plants to normal physiological phase shifting and healthy development that led to harvest in suitable time of field environmental conditions (temperature and humid) then, due to ensure high quantity and quality of cotton-seed. This study recommends that, using cottonseeds from 1 picking for early planting date as planting cotton-seeds in following seasons for gave highest seed-quality, germination%, growth, and improve productivity of cotton-yield.
