RESUMEN
AIM: The aim of the study was to examine the effect of a caring leadership intervention program for first-line nurse managers (FLNM) on their caring knowledge and managerial actions as well as nurses' perceived FLNM caring behaviours and nurse outcomes. DESIGN: A quasi-experimental study design was implemented on two groups; study and control, including 30 FLNM and 150 nurses for each. METHODS: Self-report questionnaires about FLNMs' knowledge of caring behaviours and their managerial actions, nurses perceived line nurse managers' caring behaviours and nurses' outcomes (job satisfaction and work engagement) were utilized to collect study data from 1 July 2022 to 30 December 2022. RESULTS: A statistically significant difference and changes were revealed between the study and control groups in FLNMs' caring knowledge and their managerial actions, and nurses' perceived FLNMs' caring behaviours, nurses' job satisfaction and nurses' work engagement during post-test in comparison to pre-test. Higher total mean scores of post-test in the study group were recorded compared to those of control group regarding FLNMs' caring knowledge and their managerial actions as well as nurses 'perceived FLNMs' caring behaviour, job satisfaction and work engagement. CONCLUSION: The caring leadership intervention program for FLNMs was highly effective in enhancing their caring knowledge and managerial actions as well as nurses' perceived FLNM caring behaviours and nurse outcomes. IMPLICATIONS FOR THE PROFESSION: Caring leadership can help FLNMs to create a healthy environment, resulting in a positive outcome for nurse staff, patients and healthcare organizations. PATIENT AND PUBLIC CONTRIBUTION: No patient and public contribution.

Wolf-Parkinson-White (WPW) accessory pathway (AP) may be associated with reentry supraventricular tachycardia (SVT) in addition to ventricular dyssynchrony and cardiac dysfunction. Electrophysiological studies (EPS) are the gold standard for the localization of the AP; however, 2D speckle-tracking echocardiography (2D-STE) may help in the localization of the AP noninvasively. Our study aims to evaluate the capability of 2D-STE for AP localization and the identification of AP-related contractile abnormalities and dyssynchrony in pediatric patients with WPW syndrome. This prospective multicenter cohort study involved 18 pediatric patients with ventricular preexcitation from January 2021 to January 2023. Tissue Doppler imaging (TDI), conventional echocardiography, and 2D-STE were done. Myocardial velocities, myocardial performance index (MPI), the global and segmental longitudinal strain of the left ventricle (LV), and time-to-peak longitudinal strain (TPLS) were measured before and after ablation. The longitudinal strain of the LV segments supplied by the AP, or the nearby segments close to the AP, was significantly impaired and improved after ablation (P = 0.0001). The abnormal strain pattern in the affected segments could predict the location of the AP. The TPLS of the affected segments significantly increased after ablation (P = 0.0001), denoting improved dyssynchrony. The ejection time and the LV MPI measured at the basal septum improved significantly after ablation. CONCLUSIONS: 2D STE may be used for noninvasive localization of the AP and to evaluate cardiac function and dyssynchrony in patients with WPW. Further research on more patients is necessary to validate this method for AP localization. WHAT IS KNOWN: ⢠Accessory pathways (AP) associated with the Wolf-Parkinson-White (WPW) syndrome have been linked to supraventricular tachycardia (SVT). Even without SVT, WPW can cause left ventricular dyssynchrony, contractile dysfunction, and cardiomyopathy. ⢠Electrophysiology study is the gold standard for the localization of the AP in WPW syndrome. WHAT IS NEW: ⢠The combination of 2D-speckle-tracking echocardiography (2D-STE) and the modified Arruda algorithm can precisely localize the AP associated with WPW syndrome. ⢠2D-STE can potentially assess cardiac function and dyssynchrony related to WPW syndrome. Additionally, 2D-STE can be utilized to evaluate the effectiveness of ablation in restoring cardiac function and dyssynchrony.

Introduction: There has been conclusive evidence that defunctioning stoma with either transverse colostomy or ileostomy mitigates the serious consequences of anastomotic leakage. However,whether transverse colostomy or ileostomy is preferred for defunctioning a rectal anastomosis remains controversial. The present study was designed to identify the best defunctioning stoma for colorectal anastomosis. Objective: To improve the quality of life in patients with rectal resection and anastomosis and reduce the morbidity before and after closure of the stoma. Patients and Methods The present study included 48 patients with elective colorectal resection who were randomly arranged into 2 equal groups, with 24 patients each. Group I consisted of patients who underwent ileostomy, and group II consisted of patients who underwent colostomy as a defunctioning stoma for a low rectal anastomosis. All surviving patients were readmitted to have their stoma closed and were followed-up for 6 months after closure of their stomas. All data regarding local and general complications of construction and closure of the stoma of the two groups were recorded and blotted against each other to clarify the most safe and tolerable procedure. Results: We found that all nutritional deficiencies, dehydration, electrolytes imbalance, peristomal dermatitis, and frequent change of appliances are statistically more common in the ileostomy group, while stomal retraction and wound infection after closure of the stoma were statistically more common in the colostomy group. There were no statistically significant differences regarding the total hospital stay and mortality between the two groups. Conclusion and Recommendation: Ileostomy has much higher morbidities than colostomy and it also has a potential risk of mortality; therefore, we recommend colostomy as the ideal method for defunctioning a distal colorectal anastomosis.

The present work aimed at studying the efficacy of mebendazole (MBZ) compared to artemisinin (ART) for the treatment of trichinellosis at various phases of infection. Seventy Swiss albino mice were orally infected by 300 Trichinella spiralis (T. spiralis) larvae. Mice were divided into infected untreated control group and infected groups treated with 50 mg kg-1 MBZ and 300 mg kg-1 ART for three and five consecutive days, respectively, at the enteral phase [2-4 days post infection (PI)], invasive phase (10-12 days PI) and encapsulated phase (28-30 days PI). All mice were sacrificed 35-42 days PI. MBZ and ART revealed a significant decrease in mean larval counts and increase of larval per cent reduction (LR %) when treatment was initiated during the enteral phase compared to the other phases. MBZ showed significantly higher LR % (99.7, 83.95 and 89.65%) than ART (80.58, 67.0 and 79.2%) when administered at the three infection phases. Histopathological study showed a decrease in the number of encysted larvae, their surrounding cellular infiltrates and increased regenerative muscles in all treated mice. In conclusion, ART possesses a substantial anthelmintic activity against T. spiralis infection in mice both at the enteral and encapsulated phases, yet, significantly lower than MBZ.

AIM: To evaluate systolic and diastolic cardiac function in children who had cardiomyopathy induced by ectopic atrial tachycardia (EAT). METHODS: Twenty-two pediatric patients who had cardiomyopathy induced by EAT and 25 age-matched controls were recruited in this case-control study. The patients were examined after rhythm control and normalization of their left ventricular systolic function. Different echocardiographic modalities including tissue Doppler imaging and two-dimension speckle tracking echocardiography were utilized to assess the ventricular and atrial function. RESULTS: The patients' median age was 51 months (interquartile range: 28.5-84 months). The median time interval required for normalization of left ventricular ejection fraction (EF) among patients was 1.5 months (interquartile range: 1.5-2.12 months). Compared to controls, patients had a significantly higher median left ventricular myocardial performance index (MPI) at the interventricular septum (0.44 vs. 0.38, p = .001) and left ventricular lateral wall (0.46 vs. 0.32, p = .0001). The median right ventricular MPI of the patients' group was significantly higher when compared to the control group (0.34 vs. 0.26, p = .0001). The median right atrial (RA) reservoir function in patients was significantly reduced compared to controls (30% vs. 36.63%, p = .007). CONCLUSIONS: Shortly after rhythm normalization and restoration of left ventricular EF, using tissue Doppler imaging and two-dimension speckle tracking echocardiography, children who had cardiomyopathy induced by EAT continue to have left ventricular diastolic dysfunction, right ventricular dysfunction, and reduced RA reservoir function.

The study aimed to compare the diagnostic performance of the Kato-Katz, formalin ether concentration method (FECM) and FLOTAC using Sheather's sugar solution (FS1), saturated sodium chloride (FS2) and zinc sulfate (FS7) for the diagnosis of intestinal parasites among school children, focusing on Schistosoma mansoni. Ninety fecal samples were examined using the above mentioned techniques. The overall infection rate was 87.7%. Concerning protozoa, FLOTAC (FS1 and FS2) and FECM detected nearly equal infection rates (43.3% and 44.4%, respectively) with very good agreement. Kato-Katz diagnosed the highest helminthic infection rate (57.8%) followed by FLOTAC FS7 (44.4%) and FECM showed the lowest helminthic infection rate (27.7%). As for S. mansoni, Kato-Katz showed an infection rate of 38.8% vs FLOTAC (22.2%) and FECM (11.1%). The three techniques detected the same infection rate (11.1%) with egg counts more than 72 eggs/gram of feces. The FLOTAC sensitivity and accuracy for the diagnosis of protozoa were 97% and 99%, respectively. Regarding helminths diagnosis, FLOTAC technique showed higher sensitivity (77%) and accuracy (87%) compared to FECM (48% sensitivity and 70% accuracy). Therefore, FLOTAC can be used synchronously or in replacement to other diagnostic techniques. This can strategically impact future control programmes of intestinal parasitic infections in limited resources settings.

OBJECTIVE: We aim to evaluate the midterm effect of chronic apical right ventricular (RV) pacing on right and left ventricular (LV) function using different modalities of echocardiography including conventional echocardiography, tissue Doppler imaging and two-dimension speckle tracking echocardiography. METHODS: This case-control study enrolled 49 patients divided into two groups: a paced group and a nonpaced group. The paced group included 23 patients that underwent tetralogy of Fallot (TOF) repair and required permanent pacemaker insertion for postoperative complete heart block. The nonpaced group included 26 patients that had TOF repair at the same period. RESULTS: The median age for the paced and nonpaced groups was 6 and 8 years, respectively (P = .169). The follow-up duration after TOF surgical repair was 4 years for the paced patients and 5 years for nonpaced patients (P = .411). In the nonpaced group, the QRS duration increased and LV global longitudinal strain (GLS) decreased significantly with increasing duration after TOF repair, P value was .006 and .042, respectively. In the paced group, tricuspid annular systolic plane excursion (TAPSE) was significantly correlated with age (r = .578; P = .004) and duration following TOF correction (r = .724; P < .001). CONCLUSION: Chronic RV apical pacing in children after TOF repair was associated with better clinical status, preservation of RV systolic function, and prevention of progressive QRS prolongation. RV pacing was not associated with progressive deterioration of LV systolic function with increasing the time interval following TOF repair. Therefore, RV pacing can be beneficial in corrected TOF patients presenting with RV failure.

PURPOSE: To outline the management of newly identified trematode induced uveitis in pediatric patients STUDY DESIGN: Prospective interventional case series METHODS: Patients with distinctive uveitis were recruited to either receive steroid monotherapy or undergo surgical excision of the inflammatory lesions based on a scoring system. Outcome measures included best corrected visual acuity (BCVA), intraocular inflammatory activity, and incidence of ophthalmic complications RESULTS: 170 patients (174 eyes) were recruited. Mean age was 11.1 years. Mean initial decimal BCVA (± SD) was 0.58 (± 0.31). Of 116 eyes with disease scores <5, 109 were treated effectively with steroids (93.97%). Surgical excision was offered to 58 patients and proved curative in the treated eyes. Protracted inflammation with persistence of the granulomas was noted in 5 patients refusing surgery. Mean follow up period was 21.5 months. Mean final BCVA was 0.69 (±0.27). A significant change in BCVA was noted (p=0.002). There has not been a need for retreatment in any of the study patients, who were also given instructions on evading exposure to fresh water habitats. Larger lesions, mixed disease morphology, older age at presentation were associated with higher rates of ophthalmic complications and vision loss CONCLUSION: A novel waterborne trematode inducing uveitis has been identified in Egypt. A favorable response to steroid monotherapy is demonstrated in low grade disease, while surgical excision was found to be curative in patients with larger lesions or those showing suboptimal response to medical treatment.

BACKGROUND: Swimming in contaminated water was reported to be associated with Acanthamoeba and N. fowleri human infections. The present study was carried out with the aim of isolation and identification of the different species of Acanthamoeba and Naegleria from two swimming pools in Alexandria University. METHODS: Samples were collected from the swimming pools of Alexandria University Stadium and Faculty of Agriculture-Alexandria University during the period from May 2012 to April 2013. RESULTS: Free-living amoebae were prevalent in the collected samples. Molecular characterization confirmed the identity of ten Acanthamoeba isolates and seven Naegleria isolates. Acanthamoeba T3, T4, T5, T11 and T15 genotypes were identified. Acanthamoeba T4 was the most prevalent genotype. CONCLUSION: The relatively high prevalence of Acanthamoeba, especially genotype T4, indicates the presence of a health hazard to swimmers particularly those wearing contact lenses. Naegleria fowleri was not found during the present study.
RESUMEN
The aim of this study was to study the repolarization patterns in pediatric patients with cyanotic and acyanotic congenital heart diseases as prolonged QT indicates a myocardium at risk of ventricular arrhythmia. A cross-sectional case-control study included 50 patients with acyanotic congenital heart diseases and 50 patients with cyanotic congenital heart diseases who presented to Catheterization Unit of Cairo University Pediatric Hospital between March 2013 and June 2014. We included 50 healthy children as a control. For all the patients' measurement of oxygen saturation, echocardiography and 12-lead electrocardiogram (ECG) were done and the corrected QT (QTc) was measured. The mean QTc was significantly higher in acyanotic congenital heart diseases with volume overload than in control: 0.426 versus 0.4 s (p = 0.009). Increased left ventricular end-diastolic dimension was significantly associated with QTc prolongation (p = 0.01). Early repolarization was higher in congenital heart diseases (18 % in acyanotic patient, 48 % in cyanotic patients) than in control 6 %. Decreased oxygen saturation was significantly associated with early repolarization (p = 0.01). Prolonged QTc was higher in acyanotic congenital heart diseases with volume overload and increased left ventricular end diastolic dimension was a significant association. Decreased oxygen saturation was a significant association.

Plague is a zoonotic disease with a high mortality rate in humans. Unfortunately, it is still endemic in some parts of the world. Also, natural foci of the disease are still found in some countries. Thus, there may be a risk of global plague re-emergence. This work reviews plague biology, history of major outbreaks, and threats of disease re-emergence in Egypt. Based on the suspected presence of potential natural foci in the country, the global climate change, and the threat posed by some neighbouring countries disease re-emergence in Egypt should not be excluded. The country is in need for implementation of some preventive measures.
RESUMEN
CONTEXT: Praziquantel (PZQ) is a highly efficacious anthelmintic against many flatworms including schistosomes. PZQ has been in use for more than 25 years, and concern is increasing that resistance has emerged in human schistosomes in Egypt and other endemic countries. OBJECTIVE: The current study was designed to evaluate a recently described method for induction of PZQ resistance in Schistosoma mansoni. MATERIALS AND METHODS: Successive subcurative drug treatments of Biomphalaria alexandrina snails infected with an Egyptian strain of S. mansoni were undertaken. Cercariae shed from snails exposed and unexposed to PZQ were used to infect mice. Forty-five days after infection, mice were treated with a single oral dose of PZQ in 2% aqueous solution of Cremophor-EL®. The concentration of PZQ was 0, 200, 400, or 800 mg/kg. Thirty-three days after treatment, all groups of mice were dissected to collect the S. mansoni worms by the perfusion technique. In addition, the oogram pattern was examined to study the production, maturity, and death of S. mansoni eggs in the different groups of mice. RESULTS: The present study has shown that the sublethal dose for induction of PZQ resistance in the intra-molluscan S. mansoni stages was 500 mg/kg. The worm count and the percentage of immature eggs in different groups of mice were significantly affected by the intra-molluscan exposure to PZQ and the drug concentration used to treat infected mice. DISCUSSION AND CONCLUSION: The results obtained herein confirm the possibility of using successive drug treatments of infected B. alexandrina to induce PZO resistance in S. mansoni.

BACKGROUND: Encephalitozoon cuniculi infects a wide range of homoeothermic animals, including man. Complications due to this microsporidian have been reported only in immunocompromised patients. Reports on E. cuniculi in immunocompetent humans are lacking, most probably, because it is not linked to any clinical manifestations in such hosts. The present work was carried out with the aim of studying, for the first time in Egypt, the prevalence of E. cuniculi infection of urinary tract among non-HIV immunocompromised patients and immunocompetent individuals. It tested also the influence of some factors on the risk of infection. METHODS: Blood and urine samples were collected from 88 persons (44 non-HIV immunocompromised patients and 44 subjects as immunocompetent control group). IFAT serological assay and Weber's green modified trichrome stain (MTS) urine smears were carried out. Molecular study by PCR was also performed to detect DNA of E. cuniculi in urine samples. A full history sheet was fulfilled for each subject to test the suspected risk factors. RESULTS: The IFAT examination confirmed the presence of antibodies against E. cuniculi in 44.3% of the human subjects. The seroprevalence of E. cuniculi was significantly higher in the immunocompromised patients compared with the immunocompetent individuals (77.3% versus 11.4%). Compared with IFAT (the gold standard), the sensitivity and specificity of Weber's green MTS smears were 69.23% and 89.80%. By using PCR, no positive cases were detected among human subjects. CONCLUSION: A high prevalence of E. cuniculi infection in the studied individuals was noted. Although infection was found in some immunocompetent individuals, the immune status of the host remains the corner stone for occurrence of the infection.
RESUMEN
Climate change is an emerging global issue. It is expected to have significant impacts both in Egypt and around the world. Thus, the country is in need for taking action to prepare for the unavoidable effects of climate change, including the increase in water stress, the rise in sea level, and the rapidly increasing gap between the limited water availability and the escalating demand for water in the country. Also, weather and climate play a significant role in people's health. Direct impacts of climate change on the Egyptians public health may include also increased prevalence of human parasitic diseases. Climate could strongly influence parasitic diseases transmitted through intermediate hosts. The present work reviews the future of such parasitic diseases in the view of the current available evidence and scenarios for climate change in the Egypt.
RESUMEN
BACKGROUND: Heavy metals tend to bioaccumulate in living organisms, and their accumulation has been a major concern. As mammals are known to excrete heavy metals via their bile, it seems to be very promising to analyse metal burdens of parasites that infect the biliary tree such as liver flukes of the genus Fasciola. The present study was carried out to evaluate F. hepatica and F. gigantica as bioaccumulators of heavy metals, and to estimate their use as sensitive markers of environmental pollution with heavy metals. METHODS: A total of 36 slaughtered buffaloes (26 infected and 10 controls) collected from the slaughter-house of Tanta City, Egypt were used. Samples of muscle and liver tissues were taken from each buffalo. A total of 44 adult Fasciola flukes were collected from the 26 infected buffaloes. Quantification of some heavy metals (Cd, Cr, Cu, Pb and Zn) in samples was carried out using electrothermal atomic absorption spectrometry. RESULTS: Results revealed different concentrations of heavy metals in different host tissues. The adult flukes were classified into F. hepatica (n = 25) and F. gigantica (n = 19). The bio-concentration factor (BCF) of Cr was significantly higher in F. hepatica (P = 0.0465) while BCF of Zn was significantly higher in F. gigantica (P = 0.0189). A comparative study between the two species as regards the BCF was never done before. CONCLUSION: The obtained results indicate the possibility of use of Fasciola flukes as markers of environmental pollution with some heavy metals.
RESUMEN
The conventional PCR technique was used for studying the schistosomicidal effect of Mirazid® in the murine model. Results of the molecular study were compared with the parasitological results (ova and worm count). The used PCR technique was more sensitive than the Kato-Katz thick smears. Mirazid® showed some schistosomicidal effects against murine Schistosoma mansoni. However, it was not efficient enough to cure any of the studied mice.
RESUMEN
Pediatric pacemaker (PM) implants comprise less than 1 % of all PM implants. This study aimed to investigate permanent cardiac pacing among the pediatric population, identifying different indications and complications of pediatric cardiac pacing, especially focusing on the effect of the pacing sites, the PM lead type, and the indications for pacing. The current work is a cross-sectional study of 103 procedures for permanent PM insertion in pediatric patients between January 2001 and December 2010. The patients were followed up 1, 3, and 6 months after implantation, then every 6 months or as needed. Evaluation included routine clinical examination, electrocardiography, chest X-ray, echocardiography, and a full analysis of the pacing system measurements. The ages of the patients ranged from 0.09 to 12 years (median, 2.3 years). The most common indication for pacing was postoperative complete heart bock, noted in 54 patients (52.4 %). Transvenous endocardial PM insertion was performed in 92 procedures (89.3 %), whereas transthoracic epicardial insertion was performed in 11 procedures (10.7 %). The most common site of pacing was the right ventricular apex (n = 64, 62 %), followed by the right ventricular outflow tract (n = 25, 24.3 %). Transthoracic epicardial PM insertion was associated with a significantly higher percentage and greater severity of complications. In this study, 65 % of the patients with left ventricle (LV) dilation before pacing showed a significant improvement in LV dimensions and function after pacing. This was noted only in those with endocardially inserted PM leads in both the congenital and the postoperative groups regardless of the pacing site. Endocardial PM insertion in children is a safe procedure with fewer complications and a lower ventricular threshold than the epicardial route. Permanent single-chamber right ventricle pacing is safe and can lead to significant improvement in LV function and dimensions. However, long-term follow-up assessment is needed for further evaluation.

The distribution of Schistosoma genotypes among individuals in snail populations provides insights regarding the dynamics of transmission and compatibility between schistosome and snail hosts. A survey of Biomphalaria alexandrina from Damietta (Nile Delta, Egypt), an area subjected to persistent schistosomiasis control efforts, provided only 17 snails infected with Schistosoma mansoni (6.1% overall prevalence), each shown by microsatellite analysis to have a single genotype infection. By contrast, recent studies of uncontrolled S. mansoni transmission foci in Kenya revealed that 4.3% Biomphalaria pfeifferi and 20-25% Biomphalaria sudanica snails had multiple genotype infections. Compared with the 3 Kenyan populations, the Egyptian population of S. mansoni also showed a lesser degree of genetic variability and was genetically differentiated from them. We suggest that tracking of genotype diversity in infected snails could be further developed to serve as an additional and valuable independent indicator of efficacy of schistosomiasis control in Egypt and elsewhere.

Paramphistomiasis is a disease of domestic and wild ruminants caused by some digenetic trematodes of the superfamily Paramphistomoidea. Human infections with certain species of paramphistomes have been reported. Given their ubiquity and their abundance within hosts, it seems likely that the importance of these worms is underestimated globally. Based on the reported difficulties of morphological identification of paramphistomes, the development of alternative approaches to better delineate species is needed. Paramphistome samples examined during this study were cercariae, rediae from snail hosts and adult flukes obtained from slaughterhouses from Kenya, Tanzania, Egypt and Nepal. The results confirm that ITS2 is a good molecular marker for paramphistome identification and can be used to determine the affiliation of samples among the different taxa of Paramphistomoidea. Our 22 samples include eight species of paramphistomes. Ten samples of paramphistome larvae (cercariae or rediae) yielded seven species and the 12 samples of adult flukes from bovines yielded four, only one of which was not also represented among the larvae. We found three cases in which the sequences for adult worms and larvae matched, thus revealing the hosts involved locally in those particular life cycles. We interpret our specimens to include five species from Kenya, two from Nepal, two from Tanzania and one from Egypt. Bulinus forskalii was found infected with three species of paramphistomes. The results of the present study will help construct a framework to facilitate identification and eventually control of this underestimated cosmopolitan group of digeneans.

BACKGROUND: The incidence of trocar site incisional hernia following laparoscopic surgery is reported to be relatively high. The main reasons are trocar diameter and design, pre-existing fascial defects, and some operation- and patient-related factors. The goal of this article is to present a new procedure for anatomical closure of the trocar site to prevent its herniation. METHODS: In this study, 120 patients underwent laparoscopic cholecystectomy from June 2006 through February 2009 at the General Surgery Department, Zagazig University Hospital, Egypt. After the laparoscopic procedure was complete, the trocar sites were closed in anatomical layers by using a tip hole needle and a redirecting suture hook. The mean follow-up period was 2 years for any complication at these trocar sites. RESULTS: The mean hospital stay was 1.2 days, the mean age of the patients was 49.4 years, and the mean time to place one suture was 5 min. No trocar site hernia occurred with this technique during a mean follow-up of 2 years. Seven patients developed superficial infection at the trocar site and no mortality was reported. CONCLUSION: Good closure of the trocar site in layers by using a tip hole needle and a redirecting suture hook will prevent trocar site herniation.
