Seroprevalence and associated risk factors for Fasciola hepatica in sheep in Nile Delta of Egypt

Fascioliasis is a globally distributed zoonotic parasitic disease that affects ruminants, including sheep. This study conducted from January to December 2023, aimed to determine the prevalence of Fasciola hepatica in sheep across three governorates in Egypt's Nile Delta and to assess associated risk factors. A total of 455 serum samples were analyzed using a commercial ELISA kit, revealing antibodies against F. hepatica in 22.2 % of the tested sheep. There was no significant association between locality or sex and the seroprevalence of F. hepatica in sheep; however, the highest prevalence was observed in Kafr Sheikh and in female sheep.Concerning risk factors, poor conditioned sheep aged between 1 and 2 years showed 2.1 and 3.8 times higher of infection probability than others. In addition, the risk of F. hepatica infection in sheep increased significantly in winter season (OR = 6.6, 95 %CI: 2.6–16.8), in absence of prophylactic treatment (OR = 2.2, 95 %CI: 1.3–3.3) and in presence of snail (OR = 3, 95 %CI: 3–5.4). The existence of antibodies against F. hepatica in examined sheep raising in Nile Delta indicating that the disease is reported in the studied areas and needs to be managed on farms through control and preventative measures.

An innovative approach to control fish-borne zoonotic metacercarial infections in aquaculture by utilizing nanoparticles

Fish-borne zoonotic trematodes (FBZTs) pose significant health risks and economic challenges worldwide. This study investigated the prevalence of encysted metacercariae (EMCs) in Nile tilapia (Oreochromis niloticus) from two Egyptian governorates and evaluated the antiparasitic efficacy of chitosan, silver, and selenium nanoparticles against these parasites. A cross-sectional analysis of 453 O. niloticus specimens revealed an overall EMC prevalence of 40.8%, with infection rates of 34.11% in Giza and 49.5% in Dakahlia. Clinostomid and Prohemistomid metacercariae were the most common, with mixed infections observed. Transmission electron microscopy characterized the synthesized nanoparticles, showing average diameters of 9.6–18.7 nm for chitosan, 13.2–19.8 nm for selenium, and 11.7–15.1 nm for silver nanoparticles. In vitro antiparasitic assays demonstrated varying efficacies among the nanoparticles. Against Clinostomum spp. metacercariae, chitosan nanoparticles showed the highest potency, achieving LC50 at 66 μg/ml after 30 min and LC90 at 100 μg/ml after 120 min. For Prohemistomum vivax EMCs, chitosan nanoparticles exhibited superior efficacy, achieving LC50 at 8 μg/ml after 1 h and LC90 at 16 μg/ml after 2 h. Silver and selenium nanoparticles showed lower efficacy for both parasite species. Scanning electron microscopy revealed significant ultrastructural damage to the parasite tegument following nanoparticle exposure, including disappearance of transverse ridges, integument shrinkage, and formation of blebs. This study provided valuable insights into the prevalence of FBZTs in Egyptian Nile tilapia and demonstrated the potential of nanoparticles, particularly chitosan, as effective antiparasitic agents. These findings pave the way for developing novel, targeted strategies to control fish-borne zoonotic trematodes, potentially reducing their impact on public health and aquaculture economies.

Seroprevalence of brucellosis among cows and sheep in Assiut province: A pilot study

Brucellosis is a common neglected zoonotic disease with a global geographic distribution that endangers human health and animal production. However, there is a scarcity of studies focusing on brucellosis in neglected regions such as Assiut governorate in Egypt. Therefore, the objective of this study was to investigate the prevalence of antibodies reactive to Brucella sp. in sheep and cows, as well as the associated risk factors, in Assiut governorate. A total of 184 sheep and 166 cows were included in the study, and their serum samples were subjected to screening using the Rose-Bengal plate test, followed by confirmation through the serum tube agglutination test. The overall seroprevalence of Brucella antibodies in sheep of 8.2% (15/184), while in cows, the seroprevalence was 1.2% (2/166). Among sheep, the seropositivity for Brucella abortus was 4.3% (8/184), whereas for Brucella melitensis, it was 6% (11/184). In cows, one cow displayed seropositivity for Brucella abortus, while the other exhibited mixed infection with both Brucella abortus and Brucella melitensis. Moreover, animals originating from villages bordering Sohag governorate demonstrated a higher risk of contracting brucellosis while other risk factors did not impact the occurrence of brucellosis. In conclusion, this study provides compelling evidence of the endemic nature of brucellosis in the investigated areas, with a particularly high prevalence observed in sheep. Both cows and sheep are susceptible to infection by either Brucella abortus or Brucella melitensis. To gain a comprehensive understanding of the epidemiological factors associated with infection, it is imperative to conduct large-scale surveys that incorporate molecular isolation of various Brucella species to facilitate the development of appropriate prevention strategies.

Modeling of methane emissions from waste disposal sites at selected Egyptian governorates and potential energy production from waste-to-energy projects

Waste and energy sectors have significant contributions to the greenhouse gas (GHG) emissions caused primarily by the population expansion. Waste-to-Energy (WtE) is introduced to address the issue raised by both sectors simultaneously through utilization of the potential energy stored in municipal solid waste (MSW) as well as offsetting GHG emissions. Limited research have been conducted in Egypt to assess the current situation of MSW management and associated methane emissions. The current study focused on estimating the baseline methane emissions for six Egyptian governorates and determining the energy production potential from WtE projects. To achieve this aim, three scenarios have been assessed: Baseline, Landfill Gas to Energy (LFGE), and Incineration scenarios. Key results revealed that a total of 3.7 million tonnes of methane would be emitted from all studied governorates generated over 50 years. Incineration also found to be more favorable in all governorates in terms of energy production, quantity of avoided GHG emissions, and in terms of economic viability over LFGE. Implementing incineration in all governorates would generate about 5.6 TWh energy annually and could avoid about 5 Mt CO2 eq annually in comparison to LFGE that would generate about 0.6 TWh annually and could avoid about 2.5 Mt CO2 eq annually. In terms of economic viability of WtE projects, while they were generally not economically viable under the assumptions made in the current study, incineration technology deemed promising, but policy adjustments, such as competitive Feed-in Tariff (FiT) rates and the inclusion of gate fees, are necessary. Specific minimum gate fees and FiT were identified for each governorate, providing essential guidance for decision makers to ensure the viability of WtE implementation. This study would support the decision makers in assessing technically and financially feasible options for WtE technologies in the selected governorates.

University campuses’ location-allocation: a case study of Egypt with insights from the Japanese context

PurposeThis paper aims to identify the most suitable location for a university campus in Egypt based on governorates’ social needs by employing the analytic hierarchy process (AHP). The paper, then, reflects the findings retrieved from the Egyptian context on the Japanese context to reveal how different countries deal with the location-allocation decision problem for university campuses.Design/methodology/approachThe AHP is employed to evaluate and rank Egyptian governorates based on 13 distinct criteria obtained from governmental open-source databases. These criteria measure the social needs of each governorate, guiding the decision on the location of new university campuses.FindingsThe results expose a disparity between Egypt's current campus development plan and recommendations derived from AHP analysis. The location-allocation decision for new university campuses appears to be influenced by subjective assessments, indicating a gap between planned developments and identified social needs. Additionally, contextual social and cultural differences between developing and developed countries impact the identification and fulfilment of the demand for a new university campus.Originality/valueThis paper contributes by offering decision-makers a robust location-allocation framework. It serves as a valuable tool for policy formulation in establishing new public universities in both developing and developed countries. Comparative analysis with the Japanese context enriches the understanding of how countries address the location-allocation decision problem for university campuses, emphasising the significance of context-specific considerations in such decisions.

Molecular detection of lumpy skin disease virus in naturally infected cattle and buffaloes: unveiling the role of tick vectors in disease spread.

Lumpy skin disease (LSD) is a viral disease that affects cattle and buffaloes in Egypt, causing considerable economic losses in the animal sector. This study aimed to investigate the recent outbreak of LSDV in cattle and buffaloes and evaluate the potential role of the hard tick Rhipicephalus annulatus in their transmission through isolation and molecular characterization by multiplex PCR (mPCR) and real-time quantitative PCR (rt-qPCR) assays. A total of 50 skin biopsies (cattle n = 30, buffaloes n = 20), 110 nasal swabs (cattle n = 76, buffaloes n = 44), and 129 blood samples (cattle n = 84, buffaloes n = 45) were collected. In addition, 145 hard ticks of different stages were collected from cattle and buffaloes of different breeds and ages in different governorates in Egypt from November 2021 to June 2022. Multiplex PCR and real-time quantitative PCR (rt-qPCR) assays based on SYBR Green and targets (P32, VP32, G protein, and viral fusion protein) were used. We identified positive results in 17 out of 30 cattle skin biopsies (56.6%), 1 out of 7 buffalo skin scabs (14.3%), and 5 out of 45 buffalo blood samples (11.11%) using mPCR and RT-qPCR methods. We successfully isolated LSDV from hard ticks and cattle infested with ticks and exhibited characteristic signs of LSD on the chorioallantois membrane (CAM) of specific pathogen-free embryonated chicken eggs (SPF-ECE). The isolates were confirmed by multiplex PCR and RT-qPCR. The cyclic threshold (Ct) with correlation-slandered curve values of rt-qPCR ranging from 10.2 to 36.5 showed the amount of LSDV-DNA in different samples. The study's findings demonstrated the widespread circulation of LSDV in both cattle and buffaloes in Egypt and provided strong evidence that hard ticks R. annulatus play a role in the transmission of LSDV in susceptible animals.

Allergen sensitization patterns concerning different governorates in Egypt: a retrospective study

Background Allergic disorders afflict 22% of the world’s population. Treatment and prevention of allergic diseases are dependent on correctly identifying the causal allergens and implementing appropriate avoidance approaches. We aimed to assess the variation in patterns of allergen sensitization among patients with allergic disorders in different Egyptian governorates. Methods This retrospective study included patients with allergic disorders attending an allergen immunotherapy outpatient clinic. Demographic data, diagnosis of allergic disorders, and skin prick test results of enrolled patients were retrieved from the medical records. Also, patients’ place of residence was recorded by the governorate. Results This study included 5024 patients with allergic disorders. Most of the studied patients were sensitized to mold (94.3%) followed by house dust mites (74.7%) and hay dust (69%). There was no statistical difference in allergen sensitization patterns in different Egyptian governorates. However, there was a statistically significant relation between allergic rhinitis and mixed pollen 1 (P value 0.02) and mite (P value 0.001). For bronchial asthma, both dog hair and chicken feather sensitization patterns showed a strong association with P values 0.02 and 0.03, respectively. Atopic dermatitis had a significant association with both mites (P value 0.001) and barely (P value 0.02). Conclusion The sensitization patterns did not significantly differ between the Egyptian governorates. However, it is significantly associated with allergic disorders. The most prevalent sensitization pattern in Egypt was mold.

Molecular and serological diagnosis of the circulating Trypanosoma evansi in Egyptian livestock with risk factors assessment

This study aimed to characterize and determine the prevalence and the associated risk factors of trypanosomiasis in different Egyptian livestock from various governorates using molecular and serological techniques, adding to an assessment of some biochemical alterations in serum samples. A total 1019 blood samples were collected from nine governorates in the period from January 2020 to September 2021 from cattle (n = 752), buffaloes (n = 42), sheep (n = 65), goats (n = 60), donkeys (n = 54), and horses (n = 46). Molecular investigation followed by sequencing confirmed the presence of only Trypanosoma evansi (T. evansi) infection with a prevalence rate of 3.73 % (38/1019). Serologically, T. evansi was detected by indirect ELISA in 11 samples out of 519 negative PCR ones, with an overall prevalence 2.1 %. Furthermore, statistical difference was found between investigated governorates in both molecular and seroprevalence. Surprisingly, the risk of T. evansi infection was significantly (P < 0.05) higher in winter (9.83 %) than in autumn (1.4 %), while no infection was recorded in the spring and summer seasons. No significant difference regarding animal hosts, age, and sex as risk factors was recorded. Serum biochemical analysis showed a non-significant decrease of total proteins, albumin, A/G ratio, and HDL-cholesterol in cattle, equine, and goats with a non-significant increase in total globulins level. In sheep, a significant increase was determined in all tested parameters except a significant decrease in the level of albumin and A/G ratio. To the best of our knowledge, this is the first large-scale epidemiological study determining the endemicity of the neglected T. evansi infection in different animal species in multiple governorates of Egypt. It is recommended to use both molecular and serological techniques for efficient diagnosis of trypanosomiasis as a preliminary approach to control the disease.

The effect of toxic leadership on workplace deviance: the mediating effect of emotional exhaustion, and the moderating effect of organizational cynicism

BackgroundToxic leadership is abusive, destructive, and detrimental to nurses, can decrease nurse morale, increase stress levels, diminish organizational performance, and cause employee emotional exhaustion. Emotional exhaustion, a key component of burnout, has been linked to decreased job performance and increased likelihood of engaging in deviant behaviors at work. Organizational cynicism, as a negative attitude or distrust towards the organization and its leadership, may exacerbate the relationship between toxic leadership and workplace deviance. This study aims to explore how toxic leadership, workplace deviance, emotional exhaustion, and organizational cynicism are interrelated in the nursing profession.MethodA multicenter descriptive, cross-sectional research design was conducted at three university hospitals affiliated with three Egyptian governorates: Zagazig, El-Fayoum, and Alexandria. Two hundred forty-three nurses completed the Personal and Job-related Data Questionnaire, Toxic Leadership Scale, Emotional Exhaustion Scale, Workplace Deviance Scale, and Organizational Cynicism Scale. Mediation analysis using SPSS PROCESS revealed that emotional exhaustion indirectly influences the relationship between toxic leadership and workplace deviance, while hierarchical multiple regression showed that organizational cynicism moderates this relationship, with linear regression confirming the predictive impact of these variables on workplace deviance.ResultsToxic leadership exhibits a substantial positive influence on workplace deviance (B = 16.132, p < 0.001), as does emotional exhaustion (B = 8.760, p < 0.001) and organizational cynicism (B = 5.376, p = 0.036). Furthermore, the interaction terms of toxic leadership, organizational cynicism, and emotional exhaustion are significant (B = -3.012, p = 0.036). The negative coefficient of the interaction term implies a mitigating impact, indicating that the combined presence of high toxic leadership, high emotional exhaustion, and high organizational cynicism may counterintuitively reduce workplace deviance (t = -2.110).ConclusionThese results suggest that while toxic leadership, emotional exhaustion, and organizational cynicism each independently increase workplace deviance, their combined presence may unexpectedly reduce deviant behaviors.Implication for nursingThese results highlight the significance of tackling toxic leadership practices and cultivating a positive organizational culture to enhance a healthier work environment and reduce instances of workplace deviance. Healthcare settings should prioritize interventions to improve leadership practices, enhance employee well-being, and cultivate a supportive organizational climate.

Exposure assessment of pesticide residues, heavy metals, and veterinary drugs through consumption of Egyptian fish samples

Environmental contaminants may enter seafood products either through water and sediments or via feed and feed additives or may be introduced during fish processing and storage. The study focused on the nutritional and toxicological significance of heavy metals, antibiotics, and pesticide residues in 48 fish samples collected from the Kafr-ElSheikh governorate in Egypt. Various analytical instruments are used to determine and detect heavy metals, antibiotics, and pesticides. These include Liquid Chromatography Tandem Mass Spectrometer (LC-MS/MS), Inductively Coupled Plasma Mass Spectrometer (ICP-MS), and Gas Chromatography-Mass Spectrometer (GC-MS). The following metals were discovered in fish species: arsenic (As), cadmium (Cd), cobalt (Co), copper (Cu), iron (Fe), mercury (Hg), manganese (Mn), and zinc (Zn). Each of these metals was detected 47 times. Chromium (Cr) was detected 40 times, nickel (Ni) was detected 27 times, and lead (Pb) was detected 6 times. The mean concentrations of As, Cd, Cr, Co, Cu, Fe, Ni, Mn, Hg, Pb, and Zn were determined to be 0.025, 0.02, 0.501, 0.50, 0.81, 12.56, 0.5, 0.689, 0.051, 0.031, and 5.78 mg/kg, respectively. All levels of cadmium, mercury, and lead detected in fish samples were significantly lower than the maximum permissible limits set by Egyptian and European standards. Furthermore, in this study, antibiotics and pesticide residues were found to be not detected in all analyzed fish samples. Based on the estimated daily intake and hazard quotient values, the concentration levels of metals found in fish samples seem to pose no significant threat to public health.

Monitoring the VDPV2 outbreak in Egypt during 2020–2021 highlights the crucial role of environmental surveillance and boosting immunization in combating Poliovirus

BackgroundPoliovirus is a highly infectious enterovirus (EV) that primarily affects children and can lead to lifelong paralysis or even death. Vaccine-derived polioviruses (VDPVs) are a great threat since they are derived from the attenuated virus in the Oral Poliovirus Vaccine (OPV) and can mutate to a more virulent form. The purpose of this study was to identify VDPV serotype 2 through the year 2020–2021 via surveillance of sewage samples collected from different localities and governorates in Egypt and stool specimens from Acute Flaccid Paralysis (AFP) cases. Both were collected through the national poliovirus surveillance system and according to the guidelines recommended by the WHO.MethodsA total of 1266 sewage samples and 3241 stool samples from January 2020 to December 2021 were investigated in the lab according to World Health Organization (WHO) protocol for the presence of Polioviruses by cell culture, molecular identification of positive isolates on L20B cell line was carried out using real-time polymerase chain reactions (RT-PCR). Any positive isolates for Poliovirus type 2 and isolates suspected of Vaccine Derived Poliovirus Type 1 and type 3 screened by (VDPV1) or Vaccine Poliovirus Type 3 (VDPV3) assay in RT-PCR were referred for VP1 genetic sequencing.ResultsThe outbreak was caused by circulating VDPV2 (cVDPV2) strains started in January 2021. By the end of February 2021, a total of 11 cVDPV2s were detected in sewage samples from six governorates confirming the outbreak situation. One additional cVDPV2 was detected later in the sewage sample from Qena (June 2021). The first and only re-emergence of VDPV2 in stool samples during the outbreak was in contact with Luxor in June 2021. By November 2021, a total of 80 VDPVs were detected. The Egyptian Ministry of Health and Population (MOHP), in collaboration with the WHO, responded quickly by launching two massive vaccination campaigns targeting children under the age of five. Additionally, surveillance systems were strengthened to detect new cases and prevent further spread of the virus.ConclusionThe continued threat of poliovirus and VDPVs requires ongoing efforts to prevent their emergence and spread. Strategies such as improving immunization coverage, using genetically stable vaccines, and establishing surveillance systems are critical to achieving global eradication of poliovirus and efficient monitoring of VDPVs outbreaks.

Potential human health risk assessment associated with Hg, Cd, Pb, and As in sardines and shrimp from four Egyptian coastal governorates

Heavy metal contamination in seafood is a developing concern due to the potential negative consequences on human health. Egypt's coastal regions are important for seafood production and consumption, making it critical to assess the safety of these aquatic resources. The current study examined toxic metal levels (Hg, Pb, Cd, and AS) in 96 samples of sardine and shrimp from four Egyptian coastal governorates (Alexandria, Kafr El-Sheikh, Damietta, and Port Said) from 2019 to 2021. Inductively coupled plasma-optical emission spectroscopy (ICP-OES) was used to investigate the four hazardous metals. The recovery percentages of the determined metals ranged between 97 % and 99 %. Limits of detection (LOD) and limit of quantification (LOQ) for the determined metals ranged from 0.001 to 0.0077 mg/l and from 0.0035 to 0.026 mg/l, respectively. Mercury (Hg) was not found in any of the samples tested. The concentrations of Pb and Cd in the sardines and shrimp samples were higher in the winter seasons than in the summer seasons. Meanwhile, the difference in seasons had no effect on the concentration of As in the sardines and shrimp samples. The highest concentrations of the other three metals in the sardine and shrimp samples were used to calculate the Estimated Daily Intake (EDI), Target Hazard Quotient (THQ), and Hazard Index (HI). The obtained THQ as well as the HI of Pb, Cd, and As were all less than 1.0 (with the exception of sardine samples from Kafr El-Sheikh Governorate, which recorded 1.262), indicating that there is no significant health risk to the consumer from consuming such sardines and shrimp from these governorates. The effect of different seasons on the concentrations of the metals under study does not have a specific behavior, but varies according to the governorate, the type of sample, and the type of contaminated metal. Due to the high level of contamination with heavy metals in sardine samples collected from Kafr El-Sheikh governorate (TTHQ = 1.26), an environmental study is required to determine the causes of contamination and control them.

Performance and Sustainability of Organic and Conventional Cotton Farming Systems in Egypt: An Environmental and Energy Assessment

Cotton cultivation is resource-intensive, posing significant environmental challenges, especially with conventional farming methods. Growing interest in sustainable agriculture drives the exploration of organic farming as a potential alternative with lower environmental impacts. Despite its benefits, organic farming often faces criticism for lower crop yields, sparking debates on the trade-offs between productivity and environmental impact. This study hypothesizes that organic cotton farming will have a smaller environmental footprint and higher energy efficiency compared to conventional methods. To test this hypothesis, a cradle-to-farm gate energy analysis and life cycle assessment (LCA) were conducted on both organic and conventional seed cotton production systems in the Beheira governorate of Egypt. The ReCiPe 2016 midpoint and endpoint characterization model was used for an environmental impact assessment. The impacts were evaluated using two functional units: one ton of seed cotton and one hectare of cultivated cotton. The findings revealed that organic cotton outperforms conventional cotton in net energy gain, efficiency, and profitability, with higher productivity and lower energy intensity. Regardless of the functional unit used (mass- or land-based), the assessed organic systems generally show a better environmental performance than the conventional systems in the local context, even when accounting for data uncertainty. This is due to lower input intensity and the use of less energy-intensive organic fertilizers and bio-fertilizers. Fertilization and irrigation are key factors influencing environmental impacts, with fertilization affecting midpoint impacts and irrigation affecting endpoint impacts. Therefore, precision fertilization, efficient irrigation practices, and effective nutrient and soil moisture management are recommended to minimize environmental impacts. Subsequent studies could explore whether similar patterns are observed in different geographic regions and evaluate additional social and economic aspects of cotton sustainability beyond environmental impacts. Future agricultural LCAs should use both mass-based and area-based functional units to capture a broader range of environmental effects and evaluate the co-benefits and trade-offs between organic and conventional practices.

The odds of having obesity in Egyptian children with autism spectrum disorders is higher than stunting compared to healthy developing peers: a national survey

BackgroundThe nutritional status and growth of children with Autism spectrum disorders (ASD) is influenced significantly by two factors; food selectivity behaviors due to their consumption of a limited variety of food and the high incidence of gastrointestinal (GIT) disorders.AimThis study aimed to assess the nutritional adequacy and growth pattern of ASD children aged three to twelve years compared to their healthy developing peers.MethodsA national comparative, facility-based cross-sectional study was conducted in eight Egyptian governorates on 285 Egyptian children diagnosed with ASD and 224 children who are their relatives as healthy developing peers. Anthropometric measurements were obtained, including weight, height, head circumference, and mid-upper arm circumference. Body Mass Index (BMI) was calculated and all numbers were plotted on WHO growth charts. Assessment of food preferences, and nutrient intake adequacy of children was done using the Food preference questionnaire, and the Dietary Reference Intakes (DRIs) of Egyptian children.ResultsCalorie-dense food and sugar intake were higher among ASD children than their healthy developing peers. ASD children omit some important protein sources such as dairy (COR = 5.2, 95% CI:2.7–9.9), meat, and poultry (COR = 2.7, 95% CI: 1.6–4.7), and a lower intake of fruits and vegetables than their healthy developing peers. For children with ASD in all age groups, a deficiency in the range of 50–60% was detected for vitamins (C, D, B6, thiamine, riboflavin, niacin) and minerals (iron). A deficiency in the range of 60–70% was detected for folate and calcium. A deficiency of vitamin C calcium and iron was also detected for both children with ASD and their healthy developing relatives aged 6 to 12 years. GIT disorders were common among ASD children compared to healthy developing peers (COR = 2.8 to 10.3). Children with ASD had four-fold higher odds of stunting (COR = 4.1, CI: 1.7–10.1), threefold higher odds of being overweight (COR = 3.3, CI: 1.48–7.32), and nearly eleven-fold higher odds of obesity (COR = 11.4, CI: 4.05–32.17) compared to their healthy developing peers.ConclusionASD children are prone to overweight and protein malnutrition. Their intake of fruits and vegetables is inadequate and hence their intake of vitamins and minerals is insufficient, contributing to stunting.

Root Rot Management in Common Bean (Phaseolus vulgaris L.) Through Integrated Biocontrol Strategies using Metabolites from Trichoderma harzianum, Serratia marcescens, and Vermicompost Tea

Common bean (Phaseolus vulgaris L.) is an essential food staple and source of income for small-holder farmers across Africa. However, yields are greatly threatened by fungal diseases like root rot induced by Rhizoctonia solani. This study aimed to evaluate an integrated approach utilizing vermicompost tea (VCT) and antagonistic microbes for effective and sustainable management of R. solani root rot in common beans. Fourteen fungal strains were first isolated from infected common bean plants collected across three Egyptian governorates, with R. solani being the most virulent isolate with 50% dominance. Subsequently, the antagonistic potential of vermicompost tea (VCT), Serratia sp., and Trichoderma sp. was assessed against this destructive pathogen. Combinations of 10% VCT and the biocontrol agent isolates displayed potent inhibition of R. solani growth in vitro, prompting in planta testing. Under greenhouse conditions, integrated applications of 5 or 10% VCT with Serratia marcescens, Trichoderma harzianum, or effective microorganisms (EM1) afforded up to 95% protection against pre- and post-emergence damping-off induced by R. solani in common bean cv. Giza 6. Similarly, under field conditions, combining VCT with EM1 (VCT + EM1) or Trichoderma harzianum (VCT + Trichoderma harzianum) substantially suppressed disease severity by 65.6% and 64.34%, respectively, relative to untreated plants. These treatments also elicited defense enzyme activity and distinctly improved growth parameters including 136.68% and 132.49% increases in pod weight per plant over control plants. GC–MS profiling of Trichoderma harzianum, Serratia marcescens, and vermicompost tea (VCT) extracts revealed unique compounds dominated by cyclic pregnane, fatty acid methyl esters, linoleic acid derivatives, and free fatty acids like oleic, palmitic, and stearic acids with confirmed biocontrol and plant growth-promoting activities. The results verify VCT-mediated delivery of synergistic microbial consortia as a sustainable platform for integrated management of debilitating soil-borne diseases, enhancing productivity and incomes for smallholder bean farmers through regeneration of soil health. Further large-scale validation can pave the adoption of this climate-resilient approach for securing food and nutrition security.

Resilience in the face of pandemic: exploring the influence of psychological flexibility on turnover intentions and burnout among critical care nurses in COVID-19 hospitals

AimAssess the levels of psychological flexibility, burnout, and turnover intention among critical care nurses and assess the impact of psychological flexibility on burnout, and turnover intention among critical care nurses.BackgroundBurnout and turnover intentions among critical care nurses are rapidly increasing because of the challenges of COVID-19. There is a need for evidence-based interventions like psychological flexibility to be addressed in research to overcome those challenges.MethodsA descriptive correlational research. A convenient sample of 200 critical care nurses working in COVID-19 hospitals from two governorates in Egypt. The sociodemographic and clinical data sheet, the work-related acceptance and action questionnaire, the Copenhagen burnout inventory, and the adopted version of the staff nurses’ intention to leave the nursing profession questionnaire were used.ResultsThe majority of critical care nurses reported a moderate level of psychological flexibility (75.5%, Mean = 31.23), a moderate level of burnout (65.5%, Mean = 59.61), and low to moderate levels of intention to leave (73%, Mean = 5.95). Psychological flexibility has a statistically significant negative correlation with burnout (PC = -0.304, Sig = 0.000) and the intention to leave (PC = -0.258, Sig = 0.000). In addition, psychological flexibility has a predictable effect on decreasing burnout (R2 = 0.232) and intention to leave (R2 = 0.127) among critical care nurses.Conclusioncritical care nurses in COVID-19 hospitals reported varied levels of burnout and an intention to leave that must be considered. The effect of psychological flexibility on burnout and intention to turnover highlighted the importance of improving it among critical care nurses by applying acceptance and commitment therapy as a management intervention.

Prevalence and risk factors of human papilloma virus infection among women living with HIV, Egypt, a cross sectional study

BackgroundHPV is considered the most common sexually transmitted infection. It is responsible of 70% of cervical cancers worldwide. HIV infection is associated with increased rates of HPV infection. Women Living With HIV (WLWH) are 6 times at greater risk of developing cervical cancer. The current study aimed to estimate prevalence and identify genotypes of HPV infection among WLWH in Egypt compared to women with negative HIV status and determine associated risk factors.MethodsThe study conducted among 251 WLWH and 268 women with negative HIV status enrolled from gynecological clinics in primary health care centers from nine Egyptian governorates. Data was collected from participants using a structured interview questionnaire and cervical samples were collected for HPV DNA detection and genotyping.ResultsThe overall prevalence of HPV infection was 13.5%, 3.4% among women with HIV negative status and 24.4% among WLWH. HR-HPVs other than genotype 16 and 18 were isolated from 71% of infected women. Woman’s age, age at first marriage, number of lifetime marriages and drug addiction are significant predictors for HPV infection (odds 0.96, 0.91, 2.06, 2.01 respectively).ConclusionHPV infection is more prevalent among WLWH. Infection with HR-HPV other than genotype 16 and 18 was the most prevalent among infected women in both groups. Young age, early life sexual activity, having more than one sexual partner during the life time, and drug addiction are independent predictors for HPV infection. Having a husband who has had other sexual partners is significantly associated with infection.
