Optimization of the prepared CLZ-LbPM using Design-Expert® software was achieved showing that M6 which composed of (CLZ:SPC: SDC) in respective ratios of 1:3:10 was selected as the optimized formula. The optimized formula was subjected to further evaluation tests as, Differential Scanning Calorimetry (DSC), TEM, in vitro release profile, ex vivo intranasal permeation and in vivo biodistribution.Results: The optimized formula with the highest desirability exhibiting (0.845), small particle size (12.23± 4.76 nm), Zeta potential of (− 38 mV), percent entrapment efficiency of > 90% and percent drug loading of 6.47%. Ex vivo permeation test showed flux value of 27 μg/cm².h and the enhancement ratio was about 3 when compared to the drug suspension, without any histological alteration. The radioiodinated clozapine ([131I] iodo-CLZ) and radioiodinated optimized formula ([131I] iodo-CLZ-LbPM) were formulated in an excellent radioiodination yield more than 95%. In vivo biodistribution studies of [131I] iodo-CLZ-LbPM showed higher brain uptake (7.8%± 0.1%ID/g) for intranasal administration with rapid onset of action (at 0.25 h) than the intravenous formula. Its pharmacokinetic behavior showed relative bioavailability, direct transport percentage from nose to brain and drug targeting efficiency of 170.59%, 83.42% and 117% respectively.Conclusion: The intranasal self-assembling lecithin based mixed polymeric micelles could be an encouraging way for CLZ brain targeting.Graphical Abstract: Keywords: clozapine, soy lecithin, self-assembling polymeric micelles, intranasal route, brain targeting, radioiodinated clozapine, 131I

Abstract

Background: The utility of laboratory values to predict complications in pediatric burn patients is poorly understood. This study assessed the laboratory investigations’ role in morbidities and mortalities prediction after moderate and severe thermal burn in pediatrics. Methods: This prospective cohort study was carried out on 40 children with moderate and major thermal burn. All patients were subjected to clinical evaluation and laboratory investigations such as CBC, c-reactive protein (CRP), serum albumin, serum creatinine and urea. Results: Patients were subdivided into two groups: uncomplicated group (n=25) and complicated group (n=15). CRP, serum albumin, platelet count, serum creatinine and urea can significantly predict sepsis incidence with AUC of 0.922, 0.912, 0.911, 0.807, 0.810, at cut off >12, ≤2, ≤194, >0.7, >23, with sensitivity of 100%, 90.91%, 100 %,100 %, 85.71%, specificity of 86.21 %, 86.21%, 79.31%, 24.24%, 39.39%, PPV of 73.3 %, 71.4%, 64.7%, 21.9% , 23.1% and NPV of 100 %, 96.2 %, 100 %, 100 % , 92.9% respectively. Serum creatinine and urea can significantly predict incidence of acute kidney injury (AKI) with AUC of 0.807, 0.810 At cut off >0.7, >23, with sensitivity of 100.00 %, 85.71%, specificity of 24.24%, 39.39%, PPV of 21.9%, 23.1% and NPV of 100.0%, 92.9% respectively. Percent of burn, total ABSI, CRP, platelet, inhalation injury, albumin, creatinine and urea were dependent predictors for mortality. Sex, inhalation injury, percent of burn, total ABSI, hemoglobin, CRP, platelet, albumin, and creatinine were dependent predictors for sepsis. Sex, inhalation injury, percent of burn, total ABSI, CRP, hemoglobin, platelet, albumin and creatinine were dependent predictors for complication of acute kidney disease. Conclusions: CRP, serum albumin, platelet count, serum creatinine and urea are good predictors of sepsis, AKI and mortalities after moderate to severe burn in pediatrics.

Abstract

Background Sofosbuvir (SOF) is authorized for hepatitis C virus (HCV) patients. The nephrotoxicity of SOF on HCV mono-infected and HCV–human immunodeficiency virus (HIV) individuals receiving antiretroviral therapy (ART) remains controversial. Methods A prospective study including 159 HCV mono-infected and 124 HCV–HIV individuals (47 were ART naïve and 77 were tenofovir [TDF]-based ART) who presented with an estimated glomerular filtration rate (eGFR) ≥30 ml/min/1.73 m2 at baseline and were treated with SOF–daclatasvir for 12 weeks. The eGFR was estimated using the Chronic Kidney Disease Epidemiology Collaboration equation over the study period. Results HCV patients had a progressive decline in median levels of eGFR compared with HCV–HIV patients who were ART naïve and those receiving TDF-based ART during and after discontinuing SOF–DAC treatment (96, 109 and 114 at baseline vs 94, 117 and 108 at the end of treatment [EOT]) vs 95, 114 and 115 ml/min/1.73 m2 at 12 weeks after treatment [SVR12], respectively). Moreover, the rate of eGFR stage worsening was more pronounced in HCV mono-infected compared with HCV–HIV individuals who were ART naïve and those receiving TDF-based ART (21.4% vs 8.5% and 14.3% at EOT; 21.4% vs 2.1% and 6.5% at SVR12, respectively). Multivariable regression analysis showed that baseline variables were not independent predictors of eGFR stage worsening either at EOT or SVR12. Conclusions Because the changes in eGFR were minimal and not of clinical significance, and TDF was not associated with an increase in renal dysfunction, SOF-based direct-acting antivirals could be safely used in HCV mono-infected and HCV–HIV individuals, even in those on TDF-based ART.

Abstract

Background Documentation of patterns and long-term trends in mortality in young people, which reflect huge changes in demographic and social determinants of adolescent health, enables identification of global investment priorities for this age group. We aimed to analyse data on the number of deaths, years of life lost, and mortality rates by sex and age group in people aged 10–24 years in 204 countries and territories from 1950 to 2019 by use of estimates from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019. Methods We report trends in estimated total numbers of deaths and mortality rate per 100 000 population in young people aged 10–24 years by age group (10–14 years, 15–19 years, and 20–24 years) and sex in 204 countries and territories between 1950 and 2019 for all causes, and between 1980 and 2019 by cause of death. We analyse variation in outcomes by region, age group, and sex, and compare annual rate of change in mortality in young people aged 10–24 years with that in children aged 0–9 years from 1990 to 2019. We then analyse the association between mortality in people aged 10–24 years and socioeconomic development using the GBD Socio-demographic Index (SDI), a composite measure based on average national educational attainment in people older than 15 years, total fertility rate in people younger than 25 years, and income per capita. We assess the association between SDI and all-cause mortality in 2019, and analyse the ratio of observed to expected mortality by SDI using the most recent available data release (2017). Findings In 2019 there were 1·49 million deaths (95% uncertainty interval 1·39–1·59) worldwide in people aged 10–24 years, of which 61% occurred in males. 32·7% of all adolescent deaths were due to transport injuries, unintentional injuries, or interpersonal violence and conflict; 32·1% were due to communicable, nutritional, or maternal causes; 27·0% were due to non-communicable diseases; and 8·2% were due to self-harm. Since 1950, deaths in this age group decreased by 30·0% in females and 15·3% in males, and sex-based differences in mortality rate have widened in most regions of the world. Geographical variation has also increased, particularly in people aged 10–14 years. Since 1980, communicable and maternal causes of death have decreased sharply as a proportion of total deaths in most GBD super-regions, but remain some of the most common causes in sub-Saharan Africa and south Asia, where more than half of all adolescent deaths occur. Annual percentage decrease in all-cause mortality rate since 1990 in adolescents aged 15–19 years was 1·3% in males and 1·6% in females, almost half that of males aged 1–4 years (2·4%), and around a third less than in females aged 1–4 years (2·5%). The proportion of global deaths in people aged 0–24 years that occurred in people aged 10–24 years more than doubled between 1950 and 2019, from 9·5% to 21·6%. Interpretation Variation in adolescent mortality between countries and by sex is widening, driven by poor progress in reducing deaths in males and older adolescents. Improving global adolescent mortality will require action to address the specific vulnerabilities of this age group, which are being overlooked. Furthermore, indirect effects of the COVID-19 pandemic are likely to jeopardise efforts to improve health outcomes including mortality in young people aged 10–24 years. There is an urgent need to respond to the changing global burden of adolescent mortality, address inequities where they occur, and improve the availability and quality of primary mortality data in this age group.

Abstract

Facial paralysis is a disabling deformity. The affected individual is seriously affected both esthetically and functionally. Free functional muscle transfer is currently the corner stone in the management of long-standing facial nerve paralysis. Several nerve options are available to supply the free muscle transfer. These nerves can be used alone or in combination. The aim of this work is to study the possibility and results of dually innervating the free functioning muscle transfer. The dual innervation is done using the split hypoglossal nerve and cross-face nerve graft (CFNG) both sutured in an end-to-end manner to the nerve to gracilis. Twenty-nine patients with unilateral long-standing facial nerve paralysis (more than 1 y) were treated using free gracilis muscle transfer dually supplied by the split hypoglossal nerve and CFNG, both sutured in an end-to-end manner. The gained excursion after the free gracilis transfer was 9 to 29 mm (mean: 17.24 mm). A statistically significant increase ( P -value=0.0001) in the distance from where the midline crosses the lower vermilion border to commissure occurred from preoperative (mean: 16.55 mm) to postoperative setting (mean: 33.79 mm). Spontaneity was achieved in 26 patients (89.6%). In conclusion, dual innervation of the free muscle transfer using both the split hypoglossal nerve and CFNG (both sutured in an end-to-end manner to the nerve to gracilis) is a good possible option to treat long-standing cases of facial nerve paralysis. It yields adequate muscle excursion with acceptable spontaneity.

Abstract

Background: The wrist joint is considered to be a condyloid synovial joint of the distal upper limb that connects and serves as a transition point between the forearm and hand. Hand and wrist soft tissue masses comprise a special subset of soft tissue masses. MRI imaging has an important role in characterization of soft tissue tumors, yet, it lacks specificity for differentiation between benign and malignant lesions.Diffusion-weighted imaging (DWI) is a non-invasive method for investigation of tumor histological content and used for differentiation between benign and malignant masses. Aims: This study aimed at assessment of the role of MR diffusion Weighted imaging (DWI) in the evaluation of soft tissue masses of the wrist and hand. Patients and Methods: This study conducted on 30 patients with soft tissue masses of the wrist and hand. They were referred from Orthopedic and Physiotherapy Departments to MRI unit in Radio-diagnosis Department, Tanta University Hospital. The study was conducted from November 2018 to November 2019. MRI with DWI was conducted for each one of them and results were correlated with histopathological examination. Results: There is a significant difference in the mean ADC value between benign and malignant soft tissue tumors. Increased apparent diffusion coefficient (ADC) values represent an increase in extracellular water or loss of cell membrane integrity whereas decreased ADC values reflect decrease in extracellular water content or increase in cell number or size. Conclusions: this study proved the role of MRI and supplementary Diffusion weighted image (DWI) with numerical ADC values in characterization of soft tissue masses of the wrist and hand.

Abstract

Zucchini yellow mosaic virus (ZYMV) infects cucurbits and has been identified as a major limiting factor in their production. The purpose of this study was to create copper oxide nanostructures (CONS) to control ZYMV in squash plants. Protection of squash against ZYMV was assessed in terms of virus severity, ZYMV concentration, transcription of pathogenesis-related genes and growth enhancement of treated squash.The findings revealed that squash plants treated with CONS had a significant reduction in disease severity when compared with untreated plants. In squash plants treated with CONS, defense genes associated with the salicylic acid signaling pathway were strongly expressed compared with untreated plants. The structural characteristics of CONS, such as their small size and appropriate shape, added to their excellent anti-ZYMV efficacy. CONS-treated squash plants show significantly improved growth traits compared with untreated plants.Based on the results of this study, CONS may be a new strategy for the control of ZYMV in squash. This represents an unconventional solution to control this virus, particularly as no chemical pesticides can control viral diseases. © 2022 Society of Chemical Industry.

Abstract

Background The researchers conducted the current study to explore the perspectives of people living with HIV (PLHIV) on HIV-related discrimination and the delivery of healthcare services in healthcare settings. Methods An exploratory study using a qualitative approach was conducted among 46 PLHIV who were seeking HIV counselling and treatment from two HIV centres in the Cairo governorate using a purposive sampling technique. Results A thematic content analysis was used to examine the responses. Participants had a combination of positive and negative experiences. Some participants reported staff acceptance and friendliness towards HIV-positive patients on antiretroviral treatment. Most interviewees observed that staff took extra precautions when treating or caring for them. The majority stated that counselling about the effects of the treatment was inadequate and that testing was either too far from their homes or at overcrowded centres with long waiting times. All the interviewees recommended ongoing communication and HIV counselling skills for healthcare providers who are in contact with HIV patients. Conclusion Most of the study participants were not satisfied with HIV services in the participating centres, as well as experiencing stigma. More investment in enhancing the quality of HIV service delivery and reinforcement of health worker competencies, mainly in HIV counselling, may improve satisfaction, bearing in mind HIV-related stigma in the centres involved.

Abstract

Aim: Assessment of antibacterial effect and fluoride release on glass ionomer cement (GIC) modified by different concentrations of gallic acid (GA) and their effect on working and setting time. Methodology: Four groups were tested, group I (control non modified group) and groups II-IV represent GIC modified by GA in three different concentrations (125mg/ml, 62.5mg/ml and 31.25mg/ml GA powder / GIC liquid respectively). Antibacterial effect against Streptococcus Mutans (S. Mutans) was determined after 24hr by broth dilution method. Fluoride release was evaluated after three time intervals 24, 48 and 96hr using spectrophotometer. Working and setting time were measured in all groups by indentation method. Results: Increasing the concentration of GA significantly increase the antibacterial effect. For all time intervals, the highest fluoride release were observed in group IV and the lowest were in group I. After 24hr groups II, III and IV were significant to group I, while after 48 and 96hr group IV was significant to group I. In addition, working and setting time significantly increased with increasing the GA concentration. Conclusion: Gallic acid improve the antibacterial effect of GIC against S. Mutans and also improve the fluoride release. The increase in working and setting time of GA modified groups were still within the limit given by ISO 9917–1:2007 specifications.

Abstract

Sleeping difficulties are the most significant cause of disability in menopausal women. Cognitive behavioral therapy (CBT) is the first line of management for sleeping difficulties and chronic insomnia.To evaluate the efficacy of an Internet-based CBT program on sleeping difficulties in menopausal women.This was a randomized controlled trial. A total of 80 eligible menopausal women who fit the criteria of poor sleep quality were randomly and evenly assigned to the CBT intervention group or the control group.The tools used for data collection were the demographic sheet, Pittsburgh Sleep Quality Index, Insomnia Severity Index, and sleep diary. Internet-based CBT modules were administered to the intervention group. Six consecutive modules were held weekly for each participant. Sleep quality scores and insomnia index scores were considered the primary outcomes, while sleep diaries were the secondary outcomes. Self-administered questionnaires were given at baseline and 6 weeks after randomization.Internet-based CBT is effective in reducing sleeping difficulties, particularly sleep quality scores (-3.60 ± 2.76) and insomnia index scores (-5.10 ± 3.54) from baseline. Moreover, the program induced significant changes in sleep parameters, such as increased total sleep hours (t = 2.734, p = 0.008), increased sleep efficiency ≥85%, (t = 3.558, p = 0.001), and decreased sleep latency (t = 2.180, p = 0.033) compared with the control group.The strong predictors of having very poor sleep quality were short duration since last menopause, severity of hot flashes, and short duration of sleep difficulties.Internet-based CBT is a useful practical intervention for managing sleeping difficulties in menopausal women. The current study provides evidence on the efficacy and cost-effectiveness of Internet-based cognitive behavioral intervention; thus, we recommend this method as a practical and accessible intervention to improve sleep in menopausal women.

Abstract

Background and aimIndeterminate biliary stricture (IBS) is a frequently encountered clinical problem. In this study, we aimed to highlight the clinical characteristics, risk factors and diagnostic outcomes of patients presented with indeterminate biliary stricture.MethodA Retrospective multicenter study included all patients diagnosed with IBS in the participating centers between 2017 and 2021. Data regarding IBS such as presentations, patient characteristics, diagnostic and therapeutic modalities were collected from the patients' records and then were analyzed.ResultsData of 315 patients with IBS were retrospectively collected from 7 medical centers with mean age: 62.6 ± 11 years, females: 40.3% and smokers: 44.8%. For diagnosing stricture; Magnetic resonance imaging/Magnetic resonance cholangiopancreatography (MRI/MRCP) was the most frequently requested imaging modality in all patients, Contrast enhanced computerized tomography (CECT) in 85% and endoscopic ultrasound (EUS) in 23.8%. Tissue diagnosis of cholangiocarcinoma was achieved in 14% only. The used therapeutic modalities were endoscopic retrograde cholangiopancreatography (ERCP)/stenting in 70.5%, percutaneous trans-hepatic biliary drainage (PTD): 17.8%, EUS guided drainage: 0.3%, and surgical resection in 8%. The most frequent type of strictures was distal stricture in 181 patients, perihilar in 128 and intrahepatic in 6. Distal strictures had significant male predominance, with higher role for EUS for diagnosis and higher role for ERCP/stenting for drainage, while in the perihilar strictures, there was higher role for CECT and MRI/MRCP for diagnosis and more frequent use of PTD for drainage.ConclusionIndeterminate biliary stricture is a challenging clinical problem with lack of tissue diagnosis in most of cases mandates an urgent consensus diagnostic and treatment guidelines.

Abstract

Iron overload in patients with thalassemia represents a serious complication by affecting numerous organ systems. This meta-analysis aims to establish an evidence regarding the effect of amlodipine on cardiac iron overload in thalassemia patients.We searched PubMed, Scopus, Web of Science, Cochrane Central, and EMBASE for all relevant randomized controlled trials (RCTs). The primary outcomes were cardiac T2* and myocardial iron concentration (MIC). Secondary outcomes were liver iron concentration (LIC), risk of Gastrointestinal (G.I.) upset and risk of lower limb edema. We used Hedges' g to pool continuous outcomes, while odds ratio was used for dichotomous outcomes.Seven RCTs were eligible for this systematic review and meta-analysis, comprising of 233 patients included in the analysis. Amlodipine had a statistically significant lower MIC (Hedges' g = -0.82, 95% confidence interval [CI] [-1.40, -0.24], p .001) and higher cardiac T2* (Hedges' g = 0.36, 95% CI [0.10, 0.62], p = .03). Amlodipine was comparable to standard chelation therapy in terms of the risk of lower limb edema and GI upset.Our meta-analysis found that amlodipine significantly increases cardiac T2* and decreases MIC, hence decreasing the incidence of cardiomyopathy-related iron overload in thalassemia patients.

Abstract

Background Liver biopsy is the reference standard for assessing liver fibrosis. Moreover, it is an invasive procedure. Transient elastography (TE) is an accurate, noninvasive method for evaluating liver stiffness as a surrogate of liver fibrosis. The aspartate aminotransferase to platelet ratio index (APRI) and Hyaluronic acid (HA) are noninvasive alternatives to liver biopsy for detecting hepatic fibrosis. This study aimed to identify the accuracy of APRI, HA, and TE concerning liver biopsy in children with chronic viral hepatitis. Methods This cross-sectional study included 50 children, 5–18 years with chronic viral hepatitis B (HBV) or hepatitis C (HCV) who underwent liver biopsy within nine months of laboratory tests, determining APRI & performing TE. Twenty healthy children of age and sex-matching patients were included as a control group for the serum HA levels. Results The histopathological findings of the studied cases showed seven cases with (F0) fibrosis, 36 cases with mild (F1,2), two children with moderate (F3,4), and five children with severe (F5,6). The median (IQR) of steatosis was 4 (three had HCV). When correlating TE, APRI, and HA values in all cases with their laboratory data, there was a positive correlation between ALT and APRI values (P-value = 0.000), a positive correlation between AST and HA values (P-value = 0.02), and a negative correlation between stiffness and APRI. The sensitivity of HA, APRI, and TE compared to fibrosis detected by histopathology was 60.5, 65.1, and 60.5%, and their specificity was 71.4, 57.1, and 85.7%, respectively. TE was significantly higher in a group with (moderate to severe) fibrosis. Conclusion APRI, HA, and TE are good indicators of the presence of fibrosis almost with the same accuracy. TE is the only method to differentiate mild cases from those with significant fibrosis.

Abstract

Medir la vacunación infantil de rutina es crucial para informar las políticas mundiales de vacunación y la implementación de programas, y para hacer un seguimiento del progreso hacia los objetivos establecidos por el Plan de Acción Mundial sobre Vacunas (GVAP) y la Agenda de Inmunización 2030. Se necesitan estimaciones sólidas de la cobertura de vacunación de rutina para identificar los éxitos pasados ​​y persistentes. vulnerabilidades. A partir del Estudio de la carga global de enfermedades, lesiones y factores de riesgo (GBD) 2020, versión 1, realizamos un análisis sistemático de las tendencias de cobertura de vacunas a nivel mundial, regional y nacional utilizando un marco estadístico, por vacuna y a lo largo del tiempo. Métodos Para este análisis recopilamos 55 326 observaciones específicas del país, de la cohorte, del año, de la vacuna y de la dosis de la cobertura de vacunación infantil de rutina entre 1980 y 2019. Utilizando el proceso de regresión gaussiana espaciotemporal, Estimaciones específicas por año de 11 indicadores de cobertura de vacunación infantil de rutina para 204 países y territorios desde 1980 hasta 2019, ajustando los sesgos en los datos informados por los países y reflejando los desabastecimientos informados y las interrupciones en el suministro. Analizamos las tendencias mundiales y regionales en la cobertura y el número de niños con dosis cero (definidos como aquellos que nunca recibieron una dosis de vacuna contra la difteria, el tétanos y la tos ferina [DTP]), el progreso hacia los objetivos del GVAP y la relación entre la cobertura de la vacuna y el desarrollo sociodemográfico. Recomendaciones Para 2019, la cobertura mundial de la tercera dosis de DTP (DTP3; 81,6 % [intervalo de incertidumbre del 95 % 80,4–82,7]) se duplicó con creces con respecto a los niveles estimados en 1980 (39,9 % [37,5–42 ·1]), al igual que la cobertura mundial de la vacuna antisarampionosa de primera dosis (MCV1; del 38,5 % [35,4–41,3] en 1980 al 83,6 % [82,3–84,8 ] en 2019). La cobertura de la vacuna antipoliomielítica de tercera dosis (Pol3) también aumentó, del 42,6 % (41,4–44,1) en 1980 al 79,8 % (78,4–81,1) en 2019, y la cobertura mundial de vacunas más nuevas Las vacunas aumentaron rápidamente entre 2000 y 2019. La cantidad mundial de niños que recibieron dosis cero se redujo en casi un 75 % entre 1980 y 2019, de 56,8 millones (52,6–60,9) a 14,5 millones (13,4– 15·9). Sin embargo, durante la última década, la cobertura mundial de vacunas se estabilizó en general; 94 países y territorios registraron una disminución de la cobertura de DTP3 desde 2010. Se estimó que solo 11 países y territorios alcanzaron el objetivo nacional del GVAP de al menos una cobertura del 90 % para todas las vacunas evaluadas en 2019. Interpretación Después de lograr grandes avances en la cobertura de vacunación infantil en todo el mundo, en gran parte del mundo este progreso se estancó o se revirtió de 2010 a 2019. Estos hallazgos subrayan la importancia de revisar las estrategias de inmunización de rutina y los enfoques programáticos, centrando la prestación de servicios en torno a la equidad y las poblaciones desatendidas. Fortalecer los datos de vacunas y los sistemas de monitoreo es crucial para estas actividades, ahora y hasta 2030, para garantizar que todos los niños tengan acceso y puedan beneficiarse de las vacunas que salvan vidas. Measuring routine childhood vaccination is crucial to inform global vaccine policies and programme implementation, and to track progress towards targets set by the Global Vaccine Action Plan (GVAP) and Immunization Agenda 2030. Robust estimates of routine vaccine coverage are needed to identify past successes and persistent vulnerabilities. Drawing from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2020, Release 1, we did a systematic analysis of global, regional, and national vaccine coverage trends using a statistical framework, by vaccine and over time. Methods For this analysis we collated 55 326 country-specific, cohort-specific, year-specific, vaccine-specific, and dose-specific observations of routine childhood vaccination coverage between 1980 and 2019. Using spatiotemporal Gaussian process regression, we produced location-specific and year-specific estimates of 11 routine childhood vaccine coverage indicators for 204 countries and territories from 1980 to 2019, adjusting for biases in country-reported data and reflecting reported stockouts and supply disruptions. We analysed global and regional trends in coverage and numbers of zero-dose children (defined as those who never received a diphtheria-tetanus-pertussis [DTP] vaccine dose), progress towards GVAP targets, and the relationship between vaccine coverage and sociodemographic development. Findings By 2019, global coverage of third-dose DTP (DTP3; 81·6% [95% uncertainty interval 80·4–82·7]) more than doubled from levels estimated in 1980 (39·9% [37·5–42·1]), as did global coverage of the first-dose measles-containing vaccine (MCV1; from 38·5% [35·4–41·3] in 1980 to 83·6% [82·3–84·8] in 2019). Third-dose polio vaccine (Pol3) coverage also increased, from 42·6% (41·4–44·1) in 1980 to 79·8% (78·4–81·1) in 2019, and global coverage of newer vaccines increased rapidly between 2000 and 2019. The global number of zero-dose children fell by nearly 75% between 1980 and 2019, from 56·8 million (52·6–60·9) to 14·5 million (13·4–15·9). However, over the past decade, global vaccine coverage broadly plateaued; 94 countries and territories recorded decreasing DTP3 coverage since 2010. Only 11 countries and territories were estimated to have reached the national GVAP target of at least 90% coverage for all assessed vaccines in 2019. Interpretation After achieving large gains in childhood vaccine coverage worldwide, in much of the world this progress was stalled or reversed from 2010 to 2019. These findings underscore the importance of revisiting routine immunisation strategies and programmatic approaches, recentring service delivery around equity and underserved populations. Strengthening vaccine data and monitoring systems is crucial to these pursuits, now and through to 2030, to ensure that all children have access to, and can benefit from, lifesaving vaccines.

Abstract

Background: The neonate is more susceptible to acute kidney injury (AKI) than others due to functional and developmental immaturity, hemodynamic changes that occur at birth, and possibility of hypovolemia due to increased insensible water losses. The aim of this work was early detection of the occurrence of AKI through measurement of serum cystatin C (CysC) and assessment of renal function in patients with bronchopulmonary dysplasia (BPD) in order to initiate early and appropriate therapeutic measures as indicated. Methods: This prospective observational study was carried out on 50 neonates diagnosed as cases of BPD with gestational age ranging from 28w to 38w. Urea, creatinine and serum CysC were measured twice, the first measurement was at the time of diagnosis of BPD and the second one was 3 days later with estimation of creatinine based Glomerular filtration rate (GFR) and cystatin based GFR.renal Doppler ultrasound was performed to measure peak systolivc velocity, end diastolic velocity and resistive index. Results: There were 7 cases with abnormal GFR According to the first creatinine based GFR. There were 16 cases with abnormal GFR according to the first cystatin C based GFR with no statistically significance difference between both measurements. 5 patients were classified to have AKI based on serum creatinine level. There was statistically significant increase in 1st, 2nd serum creatinine, 1st and 2nd serum cystatin C levels in the AKI patients in comparison to non AKI group. On the other hand, there was statistically significant decrease in 1st, 2nd creatinine based GFR, 1st and 2nd cystatin C based GFR. There was statistically significant increase in mortality in the AKI patients if compared to non AKI patient. There was statistically significant increase in SBP, DPB and PCO2 in the AKI patients in comparison to non AKI group. Conclusions: Measurement of serum CysC and estimation of cystatin based GFR can help in early detection of cases with renal malfunction among the patients with BPD before rise of serum creatinine Early diagnosis will lead to improvement of the outcome and shortening of the hospital stay.

Abstract

Background: Type A aortic dissection is a challenging surgical emergency associated with high morbidity and mortality. Many techniques have evolved to repair the dissected sinus segments and restore aortic valve dynamics. Herein, we evaluate the early outcome of a novel technique for reconstruction of dissected aortic root. Methods: A prospective study was conducted on 300 patients to evaluate the early results of repair of dissected root in type A aortic dissection. The mean age was 59.65±8.52 years, and 76% of patients were males. All patients had four standard steps for aortic reconstruction: 1) commissural resuspension; 2) right coronary sinus reinforcement with pericardial and Dacron bands; 3) non-coronary sinus reinforcement using external Dacron patch; 4) circumferential inversion of adventitial layer of the root. Patients were followed up clinically, echocardiographically, and by CT scan. Results: The in-hospital mortality was 8%. The mean cross-clamp time was 120±30 minutes, and circulatory arrest time was 25+10 minutes. Twenty-seven patients (9%) experienced postoperative complications, including bleeding and acute kidney injury. During a mean follow-up time of 48±12 months, there were no recurrent aortic dissection, aortic dilatation, pseudoaneurysm, or progression of aortic regurgitation during the entire study period. Conclusions: This reconstructive technique technically is undemanding, feasible, safe, and durable with good early results. A larger cohort of patients with longer period of follow up should generate a more powerful evaluation of this technique.

Abstract

Nonlinear loads have become more prevalent in all applications, including computers, transformers, and adjustable speed drives. The harmonic level of the underground distribution cables rises as a result of these loads. As a result, the cable layers' temperatures are affected by the harmonic levels. The purpose of this paper is to calculate the temperature distribution of a cable conductor and the soil around it under cyclic loading conditions, including the impact of linear and nonlinear loads. The IEC 60,853-2 standard is used to consider the thermal model of an underground cable. The finite element method is investigated to obtain a heat map of the cable layers and their surrounding soil. In this study, the small-scale model was constructed in the laboratory. The cable is installed using two methods at the same loading conditions. The heat transfer in the four-core low-voltage cable installation is measured. Furthermore, total harmonic distortion is measured using a Fluke 125 scope meter. The experimental results from the laboratory model proved that there was an extreme increase in the temperature of cable layers when the cable was installed inside the polyvinyl chloride duct in the soil compared with its installation directly buried in the soil. The results of the experimental tests are compared with simulation results.

Abstract

Conduit necrosis following colon interposition for esophageal replacement is a devastating complication with a high morbidity and mortality rates. Survivors often face a challenging journey of complex reconstructive procedures. A multi-disciplinary approach is paramount to tailor the management according to the patient's anatomy, nutritional and psychological status, conduit alternatives and routes. This case report provides a series of novel reconstructive techniques, each of which could be helpful for esophageal surgeons facing such difficult situation. A 36 years old female, with a history of corrosive ingestion at the age of 5 years, who was subjected to series of regular dilatation since then, presented with a tight stricture not passing a wire. She underwent a subcutaneous isoperistaltic left colon interposition. The postoperative course was complicated with necrosis of the cervical part of the graft with infection of the subcutaneous tunnel. Resection was done with esophagostomy and colostomy in the neck. The patient survived the acute stage, feeding was established through the colostomy opening in the neck. Delayed reconstruction was planned 6 months later. The skin between the two openings in the neck was considered posterior wall of the conduit, and transaxillary pedicled thoracodorsal artery perforator flap (TDAP) was used to reconstruct the anterior wall (1,2). Partial flap loss occurred (3). Debridment and gastrostomy were done. The result was two gaps on both ends of the flap (3). The food regurgitated upwards from the gastrostomy. An antireflux stent was placed inside the flap to bridge the defects and allow oral intake (4). The TDAP-colon side was closed using a local flap from TDAP and skin graft (5,6). The esophageal side was closed primary and covered by a supraclavicular flap (7-12). Management of graft failure should focus on controlling sepsis and nutrition. Attempts should be made to preserve any surviving part of the conduit as long as it doesn’t add to sepsis. A combination of Myocutaneous flaps could be used to replace the cervical part of the conduit as TDAP and supraclavicular flaps. Stent could be used successfully to bridge a failure in a skin flap. Finally, a dedicated team is paramount for a successful outcome.

Abstract

Background Adenomyoepithelioma of the breast is an uncommon subtype of breast neoplasm that occurs in adults over a wide age range but most commonly in middle-aged and older adults. It usually presents as a solitary palpable mass or is detected on breast radiographic images. Histologically, it is a biphasic tumor with proliferation of both the epithelial and myoepithelial components of the glands, with variable types of tissue metaplasia. Case presentation A 64-year-old Saudi woman who underwent regular breast screening (mammogram) presented to our hospital following radiographic detection of a suspicious grouped microcalcification in the upper outer quadrant of her right breast on the mammogram. A wide local excision of the right breast lump was performed. Following histopathological examination of the breast lump, the final diagnosis was breast adenomyoepithelioma with mucoepidermoid/divergent differentiation, with no evidence of malignancy. About two years after the operation, a clinical follow-up conducted outside our hospital showed the development of ductal carcinoma in situ in the same breast. Conclusion Although the prognosis and the plan of treatment remains the same, our case highlights the complexities in making an accurate diagnosis between the various types of metaplasia within adenomyoepithelioma on one hand and the presence of mucoepidermoid differentiation in adenomyoepithelioma on the other.

Abstract

BACKGROUND Induced resistance against several plant pathogens was reported using different beneficial plant growth-promoting microorganisms. The potential of five fungal isolates, Trichoderma harzianum GT 3-2, Fusarium equiseti GF 18-3, F. equiseti GF 19-1, Phoma sp. GS 10-1 and Phoma sp. GS 14-1, to stimulate tomato growth and resistance against bacterial speck disease caused by Pseudomonas syringae pathovar (pv.) tomato DC3000 was evaluated. RESULTS Based on the results of disease severity and growth promotion experiments, GF 18-3 exhibited the best results among all fungal isolates. Treatment with barley grain inocula (BGI) and culture filtrate (CF) of the isolates promoted tomato growth and suppressed the pathogen in pot trials. Furthermore, expressions of the pathogenesis-related genes (PR-1, β-1,3-glucanase A, β-1,3-glucanase B and LOX) were relatively higher than the control in the leaves of tomato plants treated with both BGI and CF. The transcription levels remained consistently higher than the control plants for 6 days post-inoculation with pathogen. CONCLUSION Taken together, the results indicate that the tested fungal isolates have the potential to promote tomato growth and induce systemic resistance against the bacterial speck disease. Analysis of certain PR gene expression revealed significant activation in both BGI and CF treatments, leading to stimulated resistance against the pathogen. © 2021 Society of Chemical Industry.

Abstract

BackgroundNumerous questions regarding procedural details of distal stroke thrombectomy remain unanswered. This study assesses the effect of anesthetic strategies on procedural, clinical and safety outcomes following thrombectomy for distal medium vessel occlusions (DMVOs).MethodsPatients with isolated DMVO stroke from the TOPMOST registry were analyzed with regard to anesthetic strategies (ie, conscious sedation (CS), local (LA) or general anesthesia (GA)). Occlusions were in the P2/P3 or A2–A4 segments of the posterior and anterior cerebral arteries (PCA and ACA), respectively. The primary endpoint was the rate of complete reperfusion (modified Thrombolysis in Cerebral Infarction score 3) and the secondary endpoint was the rate of modified Rankin Scale score 0–1. Safety endpoints were the occurrence of symptomatic intracranial hemorrhage and mortality.ResultsOverall, 233 patients were included. The median age was 75 years (range 64–82), 50.6% (n=118) were female, and the baseline National Institutes of Health Stroke Scale score was 8 (IQR 4–12). DMVOs were in the PCA in 59.7% (n=139) and in the ACA in 40.3% (n=94). Thrombectomy was performed under LA±CS (51.1%, n=119) and GA (48.9%, n=114). Complete reperfusion was reached in 73.9% (n=88) and 71.9% (n=82) in the LA±CS and GA groups, respectively (P=0.729). In subgroup analysis, thrombectomy for ACA DMVO favored GA over LA±CS (aOR 3.07, 95% CI 1.24 to 7.57, P=0.015). Rates of secondary and safety outcomes were similar in the LA±CS and GA groups.ConclusionLA±CS compared with GA resulted in similar reperfusion rates after thrombectomy for DMVO stroke of the ACA and PCA. GA may facilitate achieving complete reperfusion in DMVO stroke of the ACA. Safety and functional long-term outcomes were comparable in both groups.

Abstract

Background: Childhood obesity is unarguably a major public health challenge, which is associated with the incidence of many health problems like insulin resistance which is the main trigger of metabolic syndrome, that is characterized by many comorbidities like dyslipidemia, hypertension, diabetes, steatosis and many cardiovascular problems. Breast milk is an essential way for supplying the needed nutrients for infants’ growth and development. The aim of this work was to assess insulin resistance in obese children and adolescents and to detect its relation to duration of breastfeeding. Methods: This case controlled study was started at June 2018 till July 2020 and carried out on 120 children who were divided into 2 equal groups: Group (1) obese children. Group (2) healthy controls -of matched age and sex- that weren’t obese. Results: Weight, body mass index, waist circumference and blood pressure were significantly higher among obese children than healthy controls. There was no statistically significant difference between both groups regarding duration of breastfeeding. HOMA-IR was higher among obese children who received shorter duration of breastfeeding but without statistically significant difference. There was a significant positive correlation between HOMA-IR of obese children and both of fasting blood glucose and fasting serum insulin levels. While a significant negative correlation was observed between HOMA-IR and high density lipoproteins of obese children. Conclusion: Obese children and adolescents had higher HOMA-IR indices than healthy controls which indicate their predisposition for having insulin resistance and metabolic syndrome. HOMA-IR can be used as a useful tool for evaluation of metabolic syndrome risk in obese children as evidenced by the strong correlation between it and other components of metabolic syndrome. No significant relation was found between insulin resistance and breastfeeding duration in obese children and adolescents.

Abstract

The research objective is to design intranasal (IN) brain targeted CLZ-loaded polymeric nanomicellar systems (PNMS) aiming to improve central systemic CLZ bioavailability. Direct equilibrium method was used to prepare CLZ-PNMS using two hydrophobic poloxamines; Tetronic® 904 (T904) and Tetronic® 701 (T701) and one hydrophilic poloxamer; Synperonic® PE/F127 (F127). Optimization is based on higher percent transmittance, solubilizing efficiency, and in vitro release after 24 h with smaller particle size was achieved using Design-Expert® software. The optimized formula was further evaluated via TEM, ex vivo nasal permeation in addition to in vivo biodistribution using radiolabeling technique of the optimized formula by Technetium-99m (99mTc). The optimized formula M5 has small size (217 nm) with relative high percentage of transmittance (97.72%) and high solubilization efficacy of 60.15-fold following 92.79% of CLZ released after 24 h. Ex vivo nasal permeation showed higher flux of 36.62 μg/cm2.h compared to 7.324 μg/cm2.h for CLZ suspension with no histological irritation. In vivo biodistribution results showed higher values of radioactivity percentage of the labeled optimized formula (99mTc–M5) in brain and brain/blood ratio following IN administration of 99mTc–M5 complex which were greater than their corresponding values following intravenous route. It is obvious that nasal delivery of CLZ-PNMS could be a promising way to improve central systemic CLZ bioavailability.

Abstract

BackgroundThere is heterogeneity in the names and anatomical descriptions of regional anesthetic techniques. This may have adverse consequences on education, research, and implementation into clinical practice. We aimed to produce standardized nomenclature for abdominal wall, paraspinal, and chest wall regional anesthetic techniques.MethodsWe conducted an international consensus study involving experts using a three-round Delphi method to produce a list of names and corresponding descriptions of anatomical targets. After long-list formulation by a Steering Committee, the first and second rounds involved anonymous electronic voting and commenting, with the third round involving a virtual round table discussion aiming to achieve consensus on items that had yet to achieve it. Novel names were presented where required for anatomical clarity and harmonization. Strong consensus was defined as ≥75% agreement and weak consensus as 50% to 74% agreement.ResultsSixty expert Collaborators participated in this study. After three rounds and clarification, harmonization, and introduction of novel nomenclature, strong consensus was achieved for the names of 16 block names and weak consensus for four names. For anatomical descriptions, strong consensus was achieved for 19 blocks and weak consensus was achieved for one approach. Several areas requiring further research were identified.ConclusionsHarmonization and standardization of nomenclature may improve education, research, and ultimately patient care. We present the first international consensus on nomenclature and anatomical descriptions of blocks of the abdominal wall, chest wall, and paraspinal blocks. We recommend using the consensus results in academic and clinical practice.
