Abstract
To incorporate different concentrations of Al2O9Zr3 (1%, 5%, and 10%) nanoparticles (NP) into the ER adhesive and subsequently assess the impact of this addition on the degree of conversion, μTBS, and antimicrobial efficacy. The current research involved a wide-ranging examination that merged various investigative techniques, including the application of scanning electron microscopy (SEM) for surface characterization of NP coupled with energy-dispersive x-ray spectroscopy (EDX), Fourier-transform infrared (FTIR) spectroscopy, μTBS testing, and microbial analysis. Teeth were divided into four groups based on the application of modified and unmodified three-step ER adhesive primer. Group 1 (0% Al2O9Zr3 NPs) Control, Group 2 (1% Al2O9Zr3 NPs), Group 3 (5% Al2O9Zr3 NPs), and Group 4 (10% Al2O9Zr3 NPs). EDX analysis of Al2O9Zr3 NPs was performed showing elemental distribution in synthesized NPs. Zirconium (Zr), Aluminum (Al), and Oxides (O2). After primer application, an assessment of the survival rate of Streptococcus mutans was completed. The FTIR spectra were analyzed to observe the characteristic peaks indicating the conversion of double bonds, both before and after the curing process, for the adhesive Etch and rinse containing 1,5,10 wt% Al2O9Zr3 NPs. μTBS and failure mode assessment were performed using a Universal Testing Machine (UTM) and stereomicroscope respectively. The μTBS and S.mutans survival rates comparison among different groups was performed using one-way ANOVA and Tukey post hoc (p = .05). Group 4 (10 wt% Al2O9Zr3 NPs + ER adhesive) specimens exhibited the minimum survival of S.mutans (0.11 ± 0.02 CFU/mL). Nonetheless, Group 1 (0 wt% Al2O9Zr3 NPs + ER adhesive) displayed the maximum surviving S.mutans (0.52 ± 0.08 CFU/mL). Moreover, Group 2 (1 wt% Al2O9Zr3 NPs + ER adhesive) (21.22 ± 0.73 MPa) samples displayed highest μTBS. However, the bond strength was weakest in Group 1 (0 wt% Al2O9Zr3 NPs + ER adhesive) (14.13 ± 0.32 MPa) study samples. The etch-and-rinse adhesive exhibited enhanced antibacterial activity and micro-tensile bond strength (μTBS) when 1% Al2O9Zr3 NPs was incorporated, as opposed to the control group. Nevertheless, the incorporation of Al2O9Zr3 NPs led to a decrease in DC. RESEARCH HIGHLIGHTS: 10 wt% Al2O9Zr3 NPs + ER adhesive specimens exhibited the minimum survival of S.mutans. 1 wt% Al2O9Zr3 NPs + ER adhesive samples displayed the most strong composite/CAD bond. The highest DC was observed in Group 1: 0 wt% Al2O9Zr3 NPs + ER adhesive.

Abstract
Background Congenital mesoblastic nephroma is the most common renal tumor in children under the age of 6 months, comprising 3-10% of all kidney tumors in children. It is a rare and mostly benign tumor. It divides into cellular, classic, and mixed subtypes. It is typically detected in the third trimester of pregnancy using ultrasonography and magnetic resonance imaging. The best treatment is surgically by completely removing the tumor. Case presentation We reported a case of a one-day-old female who was born at 31 weeks gestation weighing 1670 g. Preterm labor was due to polyhydramnios, which was diagnosed predelivery. A large mass was detected in the left hypochondrium using computerized tomography, total nephrectomy was performed, and the histopathological examination of the specimen confirmed the diagnosis of congenital mesoblastic nephroma. Clinical discussion and conclusion Early polyhydramnios could be the most significant sign of renal tumors in infants, especially congenital mesoblastic nephroma.

Abstract
Repairing Pilon fractures remains challenging. ORIF allows direct anatomical reduction, but at the expense of soft tissues dissection which are associated with recovery. On the other hand, External Fixation allows indirect reduction and causes less soft tissue damage. However, a few studies conclude that External Fixation is associated with high rates of malunion.The objectives were to evaluate and compare: primary outcome measure: ankle hindfoot function (AOFAS at 9 months) and secondary outcome measures: quality of reduction, bone union, arthritic changes, other potential complications and ultimately the optimum management for pilon fractures.A prospective randomized comparative clinical study. 40 Patients were included in the study with comminuted closed Pilon fracture. Patients were randomized by closed envelope technique into two groups: Group (1) Included 20 patients managed by external fixation with limited internal fixation. Group (2) Included 20 patients managed by open reduction and internal fixation. Skeletally immature, type 43A AO/OTA, Open fractures, compartment syndrome, Pathological fractures were excluded.There was no significant difference between External fixation and ORIF as methods of fixation for Pilon fracture in the functional activity of the patient after 9 months as evidenced by AOFAS score (P=0.547) and the development of complications (P=0.227). However, there was statistically significant difference (P<0.001) regarding the time to weight bearing between both groups, and statistically significant difference (P=0.042) regarding time to union.The best surgical modality to treat Pilon fractures is still debatable. While external fixation is used by many to avoid major complications, it has been associated with high rates of malunion, and osteoarthritis.

Abstract
Hereditary neurological disorders represent a wild group of hereditary illnesses affecting mainly the nervous system, the majority of which have a Mendelian inheritance pattern. Here we present the case of two Moroccan patients each affected by a different hereditary neurological disorder. In the first patient WES analysis revealed the presence of the p.Ser72Leu de novo mutation in the PMP22 gene reported for the first time in Africa, specifically in Morocco. This variant is predicted to be in a mutation "hot-spot" region causing Dejerine-Sottas syndrome called also Charcot-Marie-Tooth type 3. The molecular modeling study suggests an important alteration of hydrogen and hydrophobic interactions between the residue in position 72 of the PMP22 protein and its surrounding amino acids. On the other hand, the p.Ala177Thr mutation on the RNASEH2B gene, responsible of Aicardi-Goutières syndrome 2, was carried in a homozygous state by the second patient descending from a consanguineous family. This mutation is common among the Moroccan population as well as in other North African countries. The present results contributed to a better follow-up of both cases allowing better symptom management with convenient treatments.

Abstract
AIMS AND OBJECTIVES Assessment of micro tensile bond strength (microTBS) and micro-leakage scores of total-etch adhesive (TAE) and self-etch adhesive (SAE) bonded to carious affected dentin (CAD) sterilized using different cavity disinfectant (curcumin photosensitizer (CP) and malachite green (MG) and Chlorhexidine (CHX) in comparison to no disinfection (ND) control group. MATERIALS AND METHODS One hundred and twenty human molars having International Caries Detection and Assessment System (ICDAS) scores of 4 and 5 were included. Visual inspection, dental explorer hardness testing, and caries detector solution using 5% basic Fuchsin dye solution was applied to dentin to identify the CAD surface. All the specimens were divided into four groups (n = 30) according to the cavity disinfectants used. Group A: 2% CHX, Group B: CP, Group C: MG, and Group D: ND. Each group was further divided into two subgroups (n = 15) based on the adhesion protocol. Groups A1, B1, C1, and D1 were held using TEA, and groups A2, B2, C2, and D2 were adhered using SEA system. The composite material was then built in 2 mm increments and then cured with light. MicroTBS and failure mode assessment using a universal testing machine (UTM) and stereomicroscope at a 40X magnification was performed on 10 samples from each subgroup. The microleakage assessment was performed using a dye penetration test on five samples from each group. ANOVA and Tukey post-hoc tests were used to compare means and standard deviation (SD) of bond strength and microleakage (p < 0.05). RESULTS The maximum microTBS was displayed by A1= CHX and TEA (13.28± 1.01 MPa). The lowest bond scores were demonstrated by C2= MG and SEA (5.98±0.44 MPa). The highest micro-leakage was exhibited by C1= MG and TEA (58.32 ± 2.11 nm). Whereas, the lowest micro-leakage values were displayed by A2= CHX and SEA (24.34± 1.11 nm). CONCLUSION Chlorohexidiene displayed better bond strength and the lowest microleakage scores with Total-etch adhesive and Self-etch adhesives when used as a cavity disinfectant. Total-etch adhesives performed better in terms of microTBS scores whereas self-etch adhesives displayed superior seal ability within the same disinfectant group.

Abstract
AIM Evaluation of the push-out bond strength (PBS) of zirconia post-bonded to radicular dentin after using different final irrigants (MTAD, Malachite green (MG), Ti-sapphire laser and Salvadora persica (S.persica). MATERIAL AND METHOD Forty human permanent single-rooted were decoronated above the cement-enamel junction. An experienced endodontist performed all the root canal instrumentation using ProTaper universal rotary files. Canals were irrigated using 5.25% NaOCl solution followed by EDTA as a final sterilant. Obturation with gutta-percha using AH Plus sealer was performed. Post-space preparation was completed using Gates Glidden and specimens were randomly assigned to four groups based on the final disinfectant received (n=10). Group 1: 5.25% NaOCl + MTAD, group 2: 5.25% NaOCl + MG, group 3: 5.25% NaOCl +Ti-sapphire laser, and group 4: 5.25% NaOCl + S. persica. The chemically polymerized resin was used to lute zirconia posts. PBS and failure mode analysis were performed using a universal testing machine and stereomicroscope at 40X magnification. Data were compared between the two groups with 95% CI using one-way analysis of variance (ANOVA) with the Tukey post hoc test. p=0.05. RESULTS Group4(5.25% NaOCl+ S.persica) specimens demonstrated the maximum (8.94±0.14 MPa) bond strength. Conversely, the apical third of Group 2 (5.25% NaOCl+ MG) (2.87±0.15 MPa) samples revealed the minimum bond strength scores. Intergroup comparison exposed that Group 1 (1.3% NaOCl+ MTAD), Group 3 (5.25% NaOCl+Ti-sapphire laser), and Group 4 (5.25% NaOCl+ S. persica) at all three-thirds unveiled no significant difference in PBS (p<0.05). CONCLUSION Ti-sapphire laser and Salvedora Persica possess the potential to be used as a final root canal irrigant to improve the push-out bond strength of zirconia post-to-root dentin.

Abstract
Aim The present cross-sectional observational study was conducted to evaluate the prevalence of halitosis among undergraduate university students at Riyadh Elm University, Riyadh, Saudi Arabia. Materials and Methods A survey of 301 participants who answered a questionnaire on their self-perceived halitosis was undertaken. Results The response rate was 35% (301/863). Of the total, 54.5% of participants reported that they had experienced halitosis. A majority of participants (61.4%) responded to having experienced an unpleasant bad taste in the morning when they woke up, with most participants (42.4%) stating that their breath was the worst early in the morning. A majority of respondents (59.6%) reported that they were aware of their condition. Only 27% of the respondents stated that they had admitted to having undergone an examination for bad breath from their dentist, and 22.9% of the respondents reported that they had undergone an examination for conditions associated with bad breath. The measures used to reduce the condition were evenly distributed, with approximately one-third using mouthwash (34.6%), gum/mentos (38.3%), and toothpaste (27.2%). Conclusion The incidence of self-perceived halitosis that was revealed in the current study is normal compare to others studies. It is unrelated to age and sex. Non-usage of dental floss, no use of mouthwash, and smoking, on the other hand, were shown to be associated with self-perceived halitosis. Furthermore, tongue cleaning was not linked to introspection halitosis. Halitosis may be also due to underlying systemic conditions. Hence it is necessary to evaluate the condition's prevalence and examine the relationship with other etiological variables with halitosis in our country.

Abstract
Objective Photon-induced photoacoustic streaming (PIPS) with pineapple peel extract (PPE) and ethylenediaminetetraacetic acid (EDTA) as a final endodontic irrigant on the push-out bond strength (PBS) of root filling material to conventional irrigation NaOCl with EDTA. Methods An in vitro study at Dar Al Uloom University was conducted over three months. Root canal preparation was performed. Based on final irrigation, all the specimens were divided randomly into four groups (n=10) Group 1: 2.25% NaOCl+ 17% EDTA (control), Group-2: 2.25% NaOCl+PIPS + 6.25% PPE, Group-3: 2.25% NaOCl+PIPS + 17% EDTA, Group-4: 2.25% NaOCl + 6.25% PPE. Canals were obturated and sealed with AH Plus sealer. Root sectioning was performed at 1mm thickness and PBS testing was performed using the universal testing machine. The debonded samples were analyzed for failure mode. ANOVA compared the means and standard deviations (SD) of all investigated group. Assessment of multiple comparisons was performed using Tukey's post hoc test. Results The maximum PBS was demonstrated by the coronal section of Group-2 (2.25%NaOCl +PIPS+6.25%PPE) specimens (8.21±0.81MPa). The apical section of Group-1 (2.25% NaOCl+17% EDTA) specimens demonstrated minimum bond strength (2.80±0.18 MPa). The intergroup comparison revealed that Group-3 (2.25% NaOCl +PIPS +17% EDTA) and Group-2 demonstrated comparable outcomes (p>0.05). Group-4 (2.25% NaOCl +6.25% PPE) specimens established significantly lower values than Group-3 and Group-4 (p<0.05). Conclusion Photon-induced photoacoustic streaming with pineapple peel extract and EDTA demonstrated better bond strength of root canal sealer and have the potential to be used as the final irrigant.

Abstract
INTRODUCTION This study aims to report on current practice in the management of radial head fractures (RHFs) in the United Kingdom and to review the literature to identify areas for future investigation. METHODS A 12-question online survey was sent to 500 surgeon members of the British Elbow and Shoulder Society in 2021. Questions focused on clinical assessment, indications for surgical treatment and willingness to participate in future studies. Descriptive statistical analysis summarised the responses. RESULTS The response rate was 20.4% (n = 102). For minimally displaced RHFs, non-operative management with immediate mobilisation was reported by 90.2% (n = 92) as opposed to 9.8% (n = 10) for initial immobilisation in plaster or brace. The most cited indication for radial head arthroplasty as opposed to fixation was increased patient age or low functional demand in 69.9% of responses (n = 71). In total, 41.2% (n = 42) indicated the need for a future randomised controlled trial (RCT) concerning the management of RHF. Only five RCTs were returned by the literature review. DISCUSSION There is considerable variability in the management of RHF among an experienced cohort of surgeons. With the interest declared by the participating surgeons, there is a call for a well-designed sufficiently powered RCT.

Abstract
AIMS The existing study aimed to assess the survival rate of S.mutans and shear bond strength (SBS) of resin adhesive restoration bonded to carious affected dentin (CAD) after using different cavity disinfectants (Chitosan, Fotoenticine®, and CO2 laser) in comparison to Chlorhexidine (CHX). MATERIALS AND METHODS The study included human mandibular molars assessed on International Caries Detection and Assessment System (ICDAS) score 4 and 5. The cusp part of the clinical crown was cut off until the reduction reaches the central fossa while being continuously supplied with water coolant till the tooth cementoenamel junction (CEJ). The root sections were embedded in polymethyl methacrylate acrylic resin followed by culturing S.mutans biofilm on the CAD surface. Specimens were arbitrarily allocated into four groups(n = 10) based on the type of disinfection. Group 1 (2% CHX), Group 2 (Chitosan), Group 3 (Fotoenticine), and Group 4 (CO2 laser). S.mutans survival rate was assessed and CAD was restored with a composite restorative material. Thermoocycling of the samples was performed and a universal testing machine (UTM) and Stereomicroscope were used to identify bond integrity and type of fracture. ANOVA and Tukey multiple comparison tests were used to assess SBS. Data on the survival rate of S. mutans were compared between groups using the nonparametric Kruskal-Wallis test RESULTS: Outcomes revealed that Group 1 (CHX) displayed the highest survival rate (0.65±0.10). However, lowest survival rate was demonstrated by Group 3 (Fotoenticine) treated specimens (0.25±0.06). It was also discovered that CHX unveiled highest bond strength values (21.48±1.39 MPa). Nevertheless, Group 2 (Chitosan) showed lowest SBS (11.01±1.00 MPa). Intergroup comparison analysis presented that group 1, and group 4 (Co2 laser) (17.76±0.41 MPa) displayed no significant difference in their bond integrity achieved. (p>0.05). However, group 3 (Fotoenticine) (16.28±0.51 MPa) and group 2 demonstrated comparable outcomes of SBS. (p>0.05) CONCLUSION: The use of CHX and CO2 lasers as disinfectants on the CAD surface resulted in a positive impact on the SBS of resin composite, according to the study's findings. However, it is worth noting that Fotoenticine exhibited better antimicrobial efficacy against S. mutans.

Abstract
AIM Evaluation of the push-out bond strength (PBS) of glass fiber reinforced post (GFRP) bonded to root dentin after canal disinfection using food-based root canal irrigants i.e., Curcumin photosensitizer (CP), Riboflavin photosensitizer (RFP), Morinda Ctrifolia juice (MCJ) and Sapindus Mukorossi (SM) along with MTAD as a final irrigant. MATERIAL METHODS Fifty human single-rooted premolar teeth were decoronated. Endodontic preparation was performed along with 2.25% sodium hypochlorite NaOCl solution followed by EDTA solution. Canals were dried and obturated followed by post-space preparation by removing GP. Specimens were allocated into five groups based on different food-based disinfection regimes (n= 10). Group 1: 2.25% NaOCl + MTAD (Control), Group 2: 6% MCJ + MTAD, Group 3: SM + MTAD, Group 4: CP + MTAD and Group 5: RFP + MTAD. All GFRP were bonded to radicular dentin. Root sectioning was performed followed by PBS and failure analysis using a universal testing machine (UTM) and stereomicroscope respectively. The data were analyzed using a one-way analysis of variance (ANOVA) test and the Post Hoc Tukey HSD test (p=0.05). RESULTS Samples disinfected with(MCJ+MTAD) at coronal third demonstrated maximum PBS (9.41±0.51 MPa). However, the apical third of group 5 (RFP + MTAD) exhibited the minimum values (4.06±0.23 MPa). Intergroup comparison analysis unveiled that group 2 (MCJ +MTAD) and group 3 (SM+MTAD) displayed comparable outcomes of PBS at all three-thirds. Similarly, samples in group 1 (2.25% NaOCl+ MTAD), group 4 (CP + MTAD), and group 5 (RFP + MTAD) exhibited comparable PBS. CONCLUSION Fruit-based irrigants Morinda Citrifolia and Sapindus Mukorossi have the potential to be used as root canal irrigants with a positive influence on bond strength.

Abstract
AIM To assess the efficacy of disinfection of caries-effected dentin (CAD) using KTP laser and different decontamination methods using ozonated water (OW), Rose Bengal photosensitizer (RBP), chlorhexidine (CHX), and Er, YAG laser on the shear bond strength (SBS) of adhesive resin bonded to deciduous teeth. MATERIAL AND METHODS A total of 50 extracted and radiographically verified carious primary molars were collected and scrutinized according to ICDAS criteria. Specimens were allocated randomly into five groups (n = 10) as per the type of CAD disinfectants. KTP laser, OW, RBP, CHX (control), and Er, YAG laser. After cavity sanitization, a resin adhesive (prime and bond NT) was smeared on the dentinal exterior followed by incremental composite filling. SBS evaluation was performed by employing specimens in the universal testing machine. The debonded surface was assessed under 40x magnification in a stereomicroscope to ascertain fracture mode. Statistical analysis was done by using the ANOVA and the Post Hoc Tukey multiple comparison tests (p < 0.05). RESULTS The highest SBS was exhibited by group 2 i.e., when OW was employed for CAD disinfection (10.25 ± 0.24 MPa). Whereas, the lowest SBS bond value was unveiled by samples in group 3 when RBP was applied for dentin surface sanitization (7.85 ± 0.59 MPa).CAD disinfection with KTP laser (8.25 ± 0.41 MPa), CHX (8.19 ± 0.73 MPa), and RBP displayed comparable bond values (p > 0.05). CONCLUSION Ozonated water and Er, YAG laser could be employed as cavity disinfectants in primary teeth as they demonstrated better shear bond strength without jeopardizing the adhesive binding capacity of restorative resins bonded to caries-affected dentin.

Abstract
OBJECTIVE The present lab-based investigation aimed at evaluating the canal disinfectants using photodynamic therapy (PDT) using different photosensitizers, conventional NaOCl, a mixture of doxycycline, citric acid, and a detergent (MTAD) and their impact on the bond strength of glass fiber post to radicular dentin. MATERIALS AND METHODS Forty extracted human premolars were gathered and disinfected. The decoration was performed up to the cementoenamel junction. Using the crown down technique cleaning of the canal was done following rinse with distilled water. All canals were dried with paper points and obturated with gutta-percha. Post space was prepared using peso reamers and samples were randomly allocated into four groups following different disinfection regimes: Group 1 - Methylene blue photosensitizer (MBP) + MTAD; Group 2 - RBP (Rose Bengal photosensitizer) + MTAD; Group 3 - CP (curcumin photosensitizer) + MTAD and Group 4 - 2.25% NaOCl + MTAD (control). Following disinfection, the canals were dried and the post was placed and cemented within the canal. Samples were dissected at coronal, middle, and apical third and placed in a universal testing machine for push-out bond strength (PBS). Debonded surfaces were evaluated for failure modes. PBS was examined using a one-way analysis of variance (ANOVA). The means of PBS were compared using Tukey multiple comparison tests with a significance threshold of (p<0.05). RESULTS Group 3 canals disinfected with CP and MTAD had the highest PBS at two levels: cervical (9.57±1.21 MPa), middle (6.37±0.79 MPa), and group 2 canal space disinfected by RBP and MTAD had the maximum PBS in apical portion (5.35±0.42 MPa). No significant difference at all root levels between group 2 (RBP + MTAD) and group 3 (p>0.05). Canal irrigation with group 1 (MBP + MTAD) and group 4 control (2.25% NaOCl + MTAD) exhibited comparable PBS at all three levels of the root. CONCLUSIONS CP, MTAD, RBP and MTAD for canal disinfection and bonding of glass fiber post to radicular dentin demonstrated comparable bond values at all three root levels and can be recommended in clinical settings after further investigations.

Abstract
Background Human papilloma virus (HPV) infection forms a major etiological factor for oropharyngeal cancer (OPC), which has exhibited increased global incidence. Aim To compare the knowledge regarding HPV, its association with OPC, and HPV vaccine among students from different countries, years of the undergraduate program, and gender. Methods The current multinational cross-sectional study was conducted in 886 undergraduate dental students from Egypt, India, Pakistan, Saudi Arabia, UAE, and Sudan through Google survey forms from July 2021 to September 2021. The survey form comprised 27 items divided into four sections. The answers to the questionnaire were compared among students from different countries, different years of the undergraduate program, and males and females. Chi-square test was used to evaluate the correlation between the demographic characteristics of students and their knowledge regarding HPV and OPC. Results Females exhibited a better knowledge regarding knowledge and perception on HPV vaccine, whereas males exhibited a better knowledge regarding HPV and its correlation with OPC, and these differences were statistically significant (P < 0.05). The third- and fourth-year undergraduate students displayed a higher awareness of OPC and its connection with HPV than other year students, and this variance was found to be statistically significant (P < 0.001). Third-year and internship students exhibited a more positive attitude and comfort regarding the vaccine and discussing the same with patients than the other educational-level students. Students from India exhibited better knowledge about HPV and its association with OPC than the students from other countries, and this difference was statistically significant (P < 0.001). Conclusion Disparities in knowledge regarding HPV-related oral cancer have been detected among the female and male participants among different nations. From the entire study population, Indian students exhibited better knowledge regarding HPV. Females from all the nations exhibited a more positive attitude and comfort regarding the vaccine and discussing the same with patients than males. The results of this necessitate intervention measures including training workshops and awareness campaigns. Improving their knowledge regarding the same may increase their awareness, resulting in better patient care.

Abstract
ObjectivesPreventing severe disease and acquiring population immunity to COVID-19 requires global immunization coverage through mass vaccination. While high-income countries are battling vaccine hesitancy, low-income and fragile nations are facing the double dilemma of vaccine hesitancy and lack of access to vaccines. There is inadequate information on any correlation between vaccine hesitancy and access to vaccines. Our study in a low-income nation aimed to fill this gap.MethodsIn the backdrop of a severe shortage of COVID-19 vaccines in Yemen, a low-income fragile nation, we conducted a nation-wide cross-sectional survey among its healthcare workers (HCWs), between 6 July and 10 August 2021. We evaluated factors influencing agreement to accept a COVID-19 vaccine and any potential correlation between vaccine acceptance and lack of access to vaccines.ResultsOverall, 61.7% (n = 975) of the 1,581 HCWs agreed to accept a COVID-19 vaccine. Only 45.4% of the participants agreed to have access to a COVID-19 vaccine, with no sex dependent variations. Although several determinants of vaccine acceptance were identified, including, having a systemic disease, following the updates about COVID-19 vaccines, complying with preventive guidelines, having greater anxiety about contracting COVID-19, previous infection with COVID-19, believing COVID-19 to be a severe disease, and lower concern about the side effects of COVID-19, the strongest was access to vaccines (OR: 3.18; 95% CI: 2.5–4.03; p-value: 0.001).ConclusionThe immediate and more dangerous threat in Yemen toward achieving population immunity is the severe shortage and lack of access to vaccines, rather than vaccine hesitancy, meaning, improving access to vaccines could lead to greater acceptance.

Abstract
Objectives Even though several effective vaccines are available to combat the COVID-19 pandemic, wide disparities in vaccine distribution, and vaccine acceptance rates between high- and low-income countries appear to be major threats toward achieving population immunity. Our global descriptive study aims to inform policymakers on factors affecting COVID-19 vaccine acceptance among healthcare workers (HCWs) in 12 countries, based on income index. We also looked for possible predictors of vaccine acceptance among the study sample. Methods A structured questionnaire prepared after consultation with experts in the field and guided by the “Report of the SAGE working group on vaccine hesitancy” was administered among 2,953 HCWs. Upon obtaining informed consent, apart from demographic information, we collected information on trust in vaccines and health authorities, and agreement to accept a COVID-19 vaccine. Results Although 69% of the participants agreed to accept a vaccine, there was high heterogeneity in agreement between HCWs in low and lower-middle income countries (L-LMICs) and upper-middle- and high-income countries (UM-HICs), with acceptance rates of 62 and 75%, respectively. Potential predictors of vaccine acceptance included being male, 50 years of age or older, resident of an UM-HIC, updating self about COVID-19 vaccines, greater disease severity perception, greater anxiety of contracting COVID-19 and concern about side effects of vaccines. Conclusions COVID-19 vaccine acceptance among HCWs in L-LMICs was considerably low as compared to those from UM-HICs. The lowest vaccine acceptance rates were among HCWs from the African continent. This underlines the need for the implementation of country-specific vaccine promotion strategies, with special focus on increasing vaccine supply in L-LMICs.

Background
Coronary artery disease (CAD) affects left ventricular (LV) systolic and diastolic function. This results in high filling pressure which expressed by different waves and may be assessed by invasive and noninvasive methods. Validation and comparing the correlation between CAD and different LV filling pressure waves may add a step forward in CAD diagnosis, prognosis and treatment.
Purpose
This study invasively validates the correlation between coronary artery disease (CAD) and left ventricular end-diastolic pressure (LVEDP) as well as left ventricular pre-A wave (LV pre-A wave) and compare the results.
Methods
124 patients who accepted to participate for this study underwent left heart catheterization for medical indications. This study obtained the results of LV filling pressures (LVEDP and LV pre-A wave), as well as, coronary angiography results with assessing the severity and extents (if CAD presents) by vessels number and Gensini Score (GS). Spearman r correlation were used for continuous/continuous or continuous/ordinal variables and Chi square test for nominal/nominal variables. Then we compared the results.
Results
CAD presence with elevated LVEDP incidence (OR = 4.29, relative risk = 1.85 P = 0.0123). Vessel number, plaque number and Gensini score correlations with LVEDP were (P = 0.0038 r = 0.34, P = 0.0002 r = 0.44, p = 0.0002 r = 0.43 and p = 0.0622 r = 0.22) respectively. In the same way, CAD presence with LV pre-a wave (OR = 2.75, relative risk = 1.5, P = 0.0447). Vessels number, plaque numbers and Gensini score relations with LV pre-A wave were (P = 0.0379 r = 0.23, P = 0.0004 r = 0.39, p = 0.0002 r = 0.40 and p = 0.0568 r = 0.21) respectively. All the results are summarized in Tables (1 + 2+3).
Conclusions
LV filling pressure had a significant correlation with CAD presence, vessel number and plaque number but it did not have a correlation with Gensini score. LVEDP had a stronger correlation with CAD presence, severity, sensitivity and extent but lower specificity than LV pre-A wave. Abstract Tables of results (1 + 2) Abstract Table of result 3

Background
Left ventricular diastolic function assessment undergoes continuous updates. EACVI/ASE 2016 guidelines handles with this case, which is an expert consensus and simplified update of the 2009 recommendations. As stated in the latest guidelines, studies need to check that the simplicity does not affect much the accuracy.
Aim
This study compares the corresponding subgroups between the 2009 and 2016 EACVI/ASE guidelines, for the assessment of left ventricular diastolic function statistically. Furthermore, it invasively validates of the relation between the grading results of each guidelines and the measured LV filling pressure during catheterization lab.
Methods
124 patients underwent transthoracic echocardiography just before angiography. A trained echo cardiographer obtained E/A mitral flow, Av E/e", LAVI, TR, septal and lateral e" and other supportive parameters to assess LV diastolic function and filling pressure according to 2009 and 2016 EACVI/ASE guidelines algorithms and we compared the results with LV pre-a wave during catheterization with a cut-off >12mmhg considered elevated.
Results
EACVI/ASE 2016 resulted in {normal (46.77%), Grade I (29.03%), Grade II (10.48%), Grade III (7.26%) and indeterminate (6.45%)}, while EACVI/ASE 2009 resulted in {normal (39.52%), Grade I (25%), Grade II (13.71%), Grade III (7.26%) and indeterminate (14.52%)} with no statically significant difference between subgroups. EACVI/ASE 2016 vs. 2009 in assessment LV filling pressure (odds ratio =0.51 and p value = 0.034. EACVI/ASE 2016 sensitivity and specificity were (0.36, 0.94 ) respectively and EACVI/ASE 2009 sensitivity and specificity were (0.63, 0.80) respectively. All results are summarized in (tables: 1 + 2+3 + 4+5 + 6).
Conclusion
This study found that the updated and simplified 2016 EACVI/ASE guidelines algorithm did not affect statistically the grading results of 2009 EACVI/ASE. Even more, 2016 had a higher relation between diastolic subgroups and invasively measured LV filling pressure which reflects the higher specificity than 2009. On the other hand 2016 was less able to detect elevated LV filling pressure which reflects a lower sensitivity than 2009. 2016 was more specific but less sensitive than 2009. There were no statistically significant difference between the means of invasively measured LV filling pressures among both guidelines. Abstract Figure. Abstract Figure.

Background
Left ventricular filling pressure assessment is a challenge. Three guidelines concerned about this are: EACVI/ASE 2016, ESC 2016 and the HFA 2019 guidelines. Echo assessment is a corner stone in their algorithms with different cutoffs and different parameters used depending on expert consensus that should be validated in an invasive manner as the authors stated.
Aims
This study validates and tests the accuracy of the different cutoffs and parameters used in echo LV filling pressure assessment in the three guidelines: EACVI/ASE 2016, ESC 2016 and HFA 2019 by direct measure in the catheterization lab.
Methods
82 patients with EF ≥ 50%, signs and symptoms of HF underwent transthoracic echocardiography immediately before catheterization. Av E/e", TR, LAVI, LVMI, RWT, LV wall thickness, Septal, lateral and mean e" were used to assess LV filling pressure with respect to EACVI/ASE 2016, ESC 2016 and HFA guidelines algorithms" different cutoffs and parameters used. This study used LV pre-A wave with a cutoff >12mmhg defined high as a reference and then we compared the results.
Results
all the results of functional and structural echo parameters" diagnostic criteria (sensitivity, specificity, NPV, PPV and accuracy) are summarized in (Table:1 + 2).
Conclusion
From an echo view, each algorithm depends on modest to high specific but low to modest sensitive echo parameters. There is no single parameter makes a guidelines superior to others. Although that the fact of combining more echo indices make the diagnosis and eventually the algorithm more reliable as in HFA 2019, that was for the cost of simplicity and ease of application. Av E/e">13 was the best cutoff (ESC 2016). Orientation for the cause of use (sensitivity, specificity, NPV or PPV) should employ the echo indices and cutoffs in best benefit, as for mitral (e"), although that septal < 7 and lateral e"<10 (EACVI/ASE 2016 and HFA 2019) had an overall more accuracy than mean e"<9 (ESC 2016), sub analysis showed that the first is better used for specificity and NPV but the latter better for sensitivity and PPV. Same idea for LVMI≥145/122 (m/f)+RWT > 0.42 (HFA 2019 major criteria) which had more specificity than LVMI≥115/95 (m/F) cutoffs (HFA2019 minor criteria and ESC2016) but in the cost of lower sensitivity, furthermore, sub analysis showed this LVMI high cutoffs were more benefit in female than in men after taking the NPV, PPV and accuracy in consideration.

Background
left ventricular (LV) diastolic function and filling pressure assessment is a challenge. ESC 2016 diastolic guidelines handles with this issue. Validation of and comparing the correlation between this guidelines and invasively measured different waves may add a step forward in the assessment, prognosis and treatment of LV diastolic function by echo.
Purpose
this study validates of the correlation of ESC 2016 left ventricular filling pressure echo guidelines with invasively measured left ventricular end-diastolic pressure and left ventricular pre-a.
Methods
124 patients who accepted to participate for this study underwent transthoracic echocardiography immediately before left heart catheterization. This study obtained echo parameters to assess LV filling pressure according to ESC 2016 algorithms. It also obtained left ventricular end-diastolic pressure (LVEDP) and LV pre-a waves during catheterization. It analyzed the data and compared the results.
Results
Correlations of grading system (normal, abnormal parameters 1,2 and 3 present) with LV pre-a and LVEDP waves were (P= < 0.0001 r = 0.47, P = 0.0027 r = 0.41), respectively. After excluding group of patients with only one abnormal parameter as indeterminate group, pressure assessment guidelines correlations with the presence of LV pre-a and LVEDP waves were (P = 0.0009 OR = 31.76, p= 0.0170 OR = 36.00), respectively. Means difference of LV pre-a and LVEDP waves between pressure guidelines presence and absence two groups were (LV pre-a: 12.72, 7.52, P < 0.0001and LVEDP: 21.03 10.36, P = 0.0043), respectively. All results are summarized in (Table:1 + 2+3 + 4+5).
Conclusion
ESC 2016 guidelines pressure assessment correlated strongly with both LV pre-a and LVEDP waves which means that the higher the number of abnormal echo parameters is resulted by echo guidelines, the higher the LV pre-a or LVEDP is presented invasively. Different approaches had different diagnostic accuracy, the best specific was cutoff≥ 2 abnormal echo parameters and the best sensitive and overall accuracy was still cutoff≥2 but after excluding only one abnormal echo parameter group as indeterminate group. The difference between means between echo guidelines pressure assessment was more significant statistically in LV pre-a wave than in LVEDP. Abstract Figure. Abstract Figure.

Background
Coronary artery disease (CAD) is a major clinical issue. CAD affects left ventricular systolic, diastolic function and LV filling pressure. Echocardiography has been known as the best noninvasive way for the assessment of systolic, diastolic function and LV filling pressure. Finding a correlation between CAD and echocardiographic parameters may help in the early assessment, prognosis and treatment of CAD.
Purpose
Finding a correlation between coronary artery disease and echocardiographic parameters with cutoffs to use in a diagnostic algorithm.
Methods
124 patients who accepted to participate for this study underwent transthoracic echocardiography immediately before their medically indicated left heart catheterization . An experienced echo cardiographer obtained mitral flow E velocity, A velocity, E/A, A duration, Av E/e", septal, lateral and mean e", pulmonary veins S velocity, D velocity, S/D, AR velocity, AR duration, AR-A duration, left atrial volume index (LAVI), tricuspid regurgitation (TR), inter ventricular septum (IVS), left inter ventricular diameter (LIVD), posterior wall diameter (PW) and some other echo parameters and assessed LV diastolic function and filling pressure according to EACVI/ASE 2016 guidelines. This study obtained angiography results and then analyzed and compared the results.
Results
Echo parameters that correlated with CAD were: EDT ≥ 160 (P = 0.0012 OR = 5.46), Av E/e" ≥ 7 (P = 0.0066 OR = 3.67), E ≥ 44 cm/s (P = 0.0026 OR = 10.00), A duration > 140 (P = 0.0256 OR = 10.50), E/A ≥ 1 (P = 0.0036 OR = 4.17) and AR duration ≥ 210 (P = 0.0001 OR = 85.00). When Cutoffs ≥ 3 present, the correlation with CAD was (P= < 0.0001 OR = 8.80) with diagnostic accuracy of (sensitivity = 0.76, specificity = 0.74, NPV = 0.68, PPV = 0.81). All the results are summarized in (Picture1:Tables 1 and 2).
Conclusion
Echo parameters (EDT, Av E/e", E velocity, A duration, E/A, AR duration) had strong correlations with the presence of coronary artery disease. The presence of three or more abnormal parameters had a significant diagnostic accuracy for CAD, and the more the abnormal parameters were positive, the higher the specificity and positive predictive value were for the diagnosis of CAD. The presence of only two abnormal parameters had a low specificity for CAD and the presence of 2016 EACVI/ASE diastolic dysfunction correlated with CAD with modest specificity which needs further assessment for the differential diagnosis. Furthermore, one or no abnormal parameters ruled out CAD with strong negative predictive value. Depending on the results of this study we kindly propose a resting echocardiographic algorithm for the diagnosis of CAD in (picture2: a proposed algorithm). Further studies should validate this algorithm and find other echo parameters especially strain echocardiography wether for resting or exercise algorithms. Abstract Tables of results Abstract Figure.

Abstract
Mandibular prognathism combined with a retrognathic maxilla is a skeletal discrepancy that is difficult to correct. We report a case of a 25-year-old Saudi male patient with skeletal class-III malocclusion due to severe prognathic mandible who was referred to an orthodontist at Prince Sultan Military Medical City. Complete clinical examination, radiographic assessment, and study models revealed class-III malocclusion due to anteroposterior deficiency of the maxilla and severe prognathic mandible. Orthognathic surgery was performed 18 months after the presurgical orthodontic phase. A 10-mm LeFort I advancement of the maxillary arch, with impaction of 3 mm, was performed with a bilateral sagittal split osteotomy (BSSO) of 11 mm. Stable occlusion and superior aesthetics were observed at the 1-year follow-up. Surgical–orthodontic treatment endows an adult patient with a class-III malocclusion or mandibular prognathism with a stable occlusion and superior aesthetics.

Abstract
Normally root canal-treated teeth are covered with crowns to prevent fracture, which becomes challenging in cases where the tooth is extensively damaged. In such instances, various restorative methods such as post-core and endocrowns have been in use. The former methodology in recent times is being discouraged owing to impending tooth weakening. Due to this reason, an uncommon type of reconstruction, endocrowns are preferred. We carried out a comparative review of restorations for endodontically treated molars.

Abstract
Dental fluorosis is a severe dental extremity due to excess fluoride intake during enamel formation, resulting in color abnormalities and severe tooth defects on its surface. This dental condition leads to abnormal appearance ranging from mild white to dark brown, affecting the esthetic characteristics and personality of the patient that eventually lowers their self-confidence. Restoration procedures and tooth-whitening procedures are the well-appreciated treatment methods for treating this anomaly. The current clinical report illustrates the minimally invasive technique for esthetic management of dental fluorosis in a 27-year-old male affected by dental fluorosis. Clinical examination revealed dental fluorosis of class II spots according to Dean's classification of fluorosis severity. The treatment plan involves minimally invasive micro-abrasion, vital teeth bleaching, and resin infiltration technique for blending different microporous lesions, mild-to-moderate fluorosis, and hypoplasia stains.

Abstract
Background: Coronavirus is an emerging respiratory pathogen that causes coronavirus disease-2019 (COVID-19), as per the Chinese Center for Disease Control and Prevention. Objective: This study aimed to assess the state of awareness and extent of knowledge about COVID-19 among dental students from India, Pakistan, and Saudi Arabia. Materials and Methods: The present descriptive cross-sectional study was conducted on 872 participants from December 2020 to January 2021. Random sampling was performed using an electronic questionnaire. One-way analysis of variance and independent sample t-test were performed to assess and compare the mean knowledge score between different demographic data. Results: Approximately 60% (n = 520) of the responders were women and 40% responders were men (n = 352). The responders were from Saudi Arabia (36.9%; n = 322), India (34.2%; n = 298), and Pakistan (28.8%; n = 252). The difference within the subgroups was statistically nonsignificant (P > 0.05), indicating that dental students of all subparameters possessed equal knowledge on COVID-19. Conclusions: Dental students possess sufficient knowledge about COVID-19, qualifying them at least to work in a medical ward. However, more emphasis must be placed on infection prevention and control policies such as hand hygiene, personal protective equipment, and pre- and postexposure prophylaxis.

Abstract
Background The gingival recession causes tooth sensitivity, poor esthetics, and tooth mobility in severe cases. Scientific documentation revealed effective root coverage (RC) and increased keratinized tissue heights acquired with the coronally advanced flap (CAF) for multiple recession defects. Objectives This research evaluates and compares the efficacy of CAF procedures with and without Type I collagen bio-absorbable membrane in guided tissue regeneration (GTR) in the treatment of Miller's Class I and II gingival recession. Materials and Methods A total of 30 sites from 15 patients were selected for the study after fulfilling the presurgical phase of treatment. The chosen sites were randomly allocated into Group A CAF and Group B (CAF + Resorbable GTR membrane). The clinical variables such as plaque index, gingival index, recession depth (RD), recession width (RW), width of keratinized gingiva (WKG), clinical attachment level (CAL), and surface area of the defect were recorded at the baseline and 6 months postoperatively. Results Both therapies resulted in a notable gain in RC with a mean of 73.13% and 71.60%, respectively, but it was not statistically significant when compared between the groups. Both the RD and RW were significantly reduced from baseline to 6 months postoperatively. Although there was a gain in WKG and CAL in both experimental sites, no significant difference was observed between both the groups. Conclusion Although there are several RC procedures, CAF furnishes a foreseeable, straightforward, and appropriate perspective for treating Miller's Class I and II recessions. Integrating this approach with placing a bio-absorbable membrane does not seem to improve the results following surgical treatment of such defects. However, both groups showed the potential advantage of achieving RC.

Abstract
Background
Left ventricle diastolic function and filling pressures assessment is still a major challenge to echocardiographer. There are two echo guidelines regarding this issue: the British Society of Echocardiography (BSE 2013) and the American Society of Echocardiography/European Association of Cardiovascular Imaging (ASE/EACVI 2016). The 2016 guidelines, which is an expert consensus and simplified update of 2009 guidelines, needs an invasive validation according to its authors. Recent studies raised questions about the diagnostic accuracy as sensitivity results varied very widely (34% to 87%) and also that of 2009 (43% to 79%). This study validated the diastolic pressure invasively in the cath lab and compared the results with the echo guidline algorithms were done immediately before the catheterization. When possible, it included additional assessment of S/D and Ar-A duration.
Purpose
Validation of the diagnostic accuracy of the 2009, the updated 2016 ASE/EACVI and 2013 BSE echocardiographic LV filling pressure predicting algorithms, as well as pulmonary veins flow (S/D) and (Ar-A) durations with invasively measured LV-pre-A wave.
Methods
124 patients (58.06% males) underwent transthoracic echocardiography immediately before left heart catheterization. A trained echocardiographer obtained E/A mitral flow, E/e', left atrial volume index, TR, EDT, lateral and septal e' to estimate LV filling pressure as normal, elevated or indeterminate using the 2009, 2016
ASE/EACVI algorithms and 2013 BSE algorithm. He also obtained Secondary parameters as (S/D) and (Ar-A) duration. Invasive LV pre-A pressure was the reference of this study, with >12 mm Hg defined as elevated.
Results
Invasive LV pre-A pressure was elevated in 60 (48.38%) patients. When they could determine LV filling pressure, 2016 sensitivity was 0.36 and specificity 0.94, 2009 had 0.56 sensitivity and 0.90 specificity and 2013 resulted in 0.63 sensitivity and 0.80 specificity. Results of diagnostic accuracy of each algorithm as well as (S/D) and (Ar-A) summarized in tables associated in (picture 1: Tables of results). EDT≥150 msec raised NPV in normal, grade one diastolic dysfunction and indeterminate pressure.
Conclusion
2016 was the most specific but the least sensitive with modest NPV and PPV between the 2013 and 2009. 2013 was the most sensitive with the highest indeterminate pressure rate to execlude. Adding S/D or Ar-A duration markedly improved the sensitivity and reduced class indeterminate among all algorithms with more benefit when both combined. EDT had a rule out role in normal, grade one diastolic dysfunction and indeterminate pressure patients. We kindly propose a modification of 2016 algorithm by adding S/D, Ar-A and EDT as optional parameters to increase sensitivity and reduce indeterminate class without affecting simplicity or specificity (picture 2: Proposed algorithms A+B). We recommend future studies to validate the diagnostic accuracy of the proposed algorithms.

Abstract
The long-term solution to managing the current COVID-19 pandemic is through mass immunization of the population. However, uncertainty or unwillingness to receive the vaccine could be a barrier in attaining sufficient vaccine coverage. Therefore, understanding the psychology of the population towards the vaccines against COVID-19 is of paramount importance. Our study was aimed at determining the predictors of COVID-19 vaccine intention in the Saudi Arabian population. A structured questionnaire guided by the 'Report of the SAGE working group on vaccine hesitancy' was administered during a span of two months among the general population from all administrative regions of Saudi Arabia, proceeding the launch of the vaccination campaign. In total, 879 out of 1600 subjects responded and completed the survey (response rate 54.9%). About 56 percent of the participants intended to be vaccinated. The predictors of a higher intention to vaccinate included those 50 years of age or older, male subjects, people suffering from systemic disease/s, subjects who were not previously infected with COVID-19, those who follow the updates about COVID-19 vaccines, and adults with a higher level of anxiety about contracting coronavirus (p < 0.05). Results from our study and other similar studies can aid policy makers and stakeholders in planning effective strategies based on the changing behavior of the population.

Type of funding sources: None.
Background
Differences in spatial resolution and image filtering between the solid-state DSPECT and traditional Anger SPECT (A-SPECT) cameras are likely to result in differences in LV measurements. However, DSPECT- specific normal values have not been systematically derived. We used healthy organ-donor subjects from our high-volume solid organ transplant center for derivation of normal values.
Purpose
To report DSPECT-specific LV measurements normal limits derived from a unique cohort of donor subjects.
Methods
Subjects were 92 consecutive kidney or liver donors who underwent single day rest (5 mCi)- stress (15mCi) Tc-99m sestamibi gated SPECT myocardial perfusion imaging (MPI) on the DSPECT for pre-operative evaluation. Exclusion criteria included any cardiac disease or medications. LV measurements were made on the post-stress supine stress images using QGS®.
Results
Of 92 subjects (mean age 54.4 ± 15.0 and 39% men), mean EF for women and men were 77.2 ± 14.1% and 70.0 ± 14.7%, respectively. Mean end-diastolic volume for women and men were 67.0 ± 32.2 ml and 99.6 ± 51.6 ml (indexed 38.3 ± 17.2 ml/m2 and 48.1 ± 25.9 ml/m2), respectively. Mean LV wall volume for women and men were 95.9 ± 26.0 ml and 112.0 ± 48.8 ml (indexed 55.0 ± 13.8 ml/m2 and 54.1 ± 24.6 ml/m2), respectively.
Conclusion
We report DSPECT-specific LV measurements from normal subjects from which limits of normality can be derived for clinic use. Organ-donors who undergo pre-operative MPI are a suitable cohort for the derivation of normal values.

Abstract
INTRODUCTION Holmes Tremor (HT) is a unique and debilitating movement disorder. It usually results from lesions of the midbrain and its connection but can also result from posterior thalamic injury. Clinical examination can help lesion localization between these two areas. We studied the clinical features and their radiological correlations to distinguish midbrain HT (HT-m) from thalamic HT (HT-t). METHODS Retrospective review of 17 patients with a HT-type presentation was conducted. Tremor characteristics, associated clinical signs and radiological findings were studied. RESULTS Eleven patients had a myorythmic rest tremor, large amplitude proximal tremor with goal-directed worsening, with or without mild distal dystonic posturing, representing HT-m. Six patients had slow, large amplitude proximal tremors and distal choreathetoid movements, significant proximal/distal dystonic posturing, associated with proprioceptive sensory loss, representing HT-t. Haemorrhagic lesions were the predominant cause of HT-m; whereas, ischaemia was more commonly associated with HT-t. CONCLUSION When assessing patients with HT, attentiveness to the presence of associated signs in the affected limb, such as a proprioceptive sensory deficits and additional movement disorders, can aid lesion localisation, which can have implications for management.

Abstract
Background There is little evidence on techniques for management of peri-prosthetic infection (PJI) in the context of severe proximal femoral bone loss. Custom-made articulating spacers (CUMARS) utilising cemented femoral stems as spacers was described providing better bone support and longer survival compared to conventional articulating spacers. We retrospectively report our experience managing PJI by adaptation of this technique using long cemented femoral stems where bone loss precludes use of standard stems. Methods Patients undergoing 1st stage revision for infected primary and revision THA using a cemented long stem (> 205 mm) and standard all-polyethylene acetabulum between 2011 and 2018 were identified. After excluding other causes of revision (fractures or aseptic loosening), Twenty-one patients remained out of total 721 revisions. Medical records were assessed for demographics, initial microbiological and operative treatment, complications, eradication of infection and subsequent operations. 2nd stage revision was undertaken in the presence of pain or subsidence. Results Twenty-one patients underwent 1st stage revision with a cemented long femoral stem. Mean follow up was 3.9 years (range 1.7–7.2). Infection was eradicated in 15 (71.4%) patients. Two patients (9.5%) required repeat 1st stage and subsequently cleared their infection. Three patients (14.3%) had chronic infection and are on long term suppressive antibiotics. One patient (4.8%) was lost to follow up before 2 years. Complications occurred in seven patients (33%) during or after 1st stage revision. Where infection was cleared, 2nd stage revision was undertaken in 12 patients (76.5%) at average of 9 months post 1st stage. Five (23.8%) CUMARS constructs remained in-situ at an average of 3.8 years post-op (range 2.6–5.1). Conclusions Our technique can be used in the most taxing of reconstructive scenarios allowing mobility, local antibiotic delivery, maintenance of leg length and preserves bone and soft tissue, factors not afforded by alternative spacer options.

Abstract
IntroductionThe implementation of Intensive Home Treatment (IHT) aims to decrease the pressure on acute inpatient services that could lead to prevent hospitalization and reduce the number of hospitalization days and, ultimately, reduce cost in the mental health services. Although there are studies assessing the effectiveness of IHT, there is a shortage of research studying the cost-effectiveness.ObjectivesThe aim of this study is to present an cost-utility analysis of IHT compared to care as usual (CAU)MethodsPatients between 18 and 65 years of age whose mental health professionals considered hospitalization were included. These patients were pre-randomized in either IHT or CAU and followed up for 12-months. For this study, the base case analysis was performed from the societal and healthcare perspective. For the cost-utility analyses the Euroqol 5D was used to calculate quality adjusted life years (QALYs) as a generic measure of health gains.ResultsData of 198 patients were used. From a sociatal perspective, the cost-utility analysis resulted in an incremental cost-effectiveness ratios (ICERs) of €58 730, and a 37% likelihood that IHT leads to higher QALYs at lower costs. The probability of IHT being cost-effective was >50% if there was no willingness to pay more for extra QALY than in the current situation under CAU.ConclusionsProfessionals working in crisis care are able to offer IHT with the same effect as other crisis care interventions at lower costs. IHT seem to be cost-effective compared with CAU over 52 weeks follow-up for patients who experience psychiatric crises.DisclosureNo significant relationships.

Abstract
Abstract The haemostatic efficacy of different extract types of Satureja thymbra L., Thymbra spicata L. (Lamiaceae) and Verbascum fruticulosum Post. (Scrophulariaceae) was evaluated in this study via the Prothrombin time (PT) and Activated partial thromboplastin time (aPTT) analysis. Aqueous, methanol and ethanol extracts of the examined plant species leaves were prepared to a final concentration 50 mg/mL. In vitro PT and aPTT assays were conducted on normal platelet poor plasma blood samples by a digital coagulation analyzer. The obtained results revealed anticoagulation activity of all investigated plant species with observed variations among them. The aqueous and ethanol extracts of T. spicata as well as the aqueous extract of S. thymbra prolonged PT values significantly (p < 0.05). While, all V. fruticulosum extract types have had no significant effect on the PT values. The recorded aPTT data showed that all aqueous extracts have had a significant effect on the blood haemostasis as they increased aPTT values in all plant species under study. Out of which, both the ethanol and methanol extracts of T. spicata and methanol extract of S. thymbra showed similar effect. Of great concern, it was clearly noticed that the aqueous and ethanol extract of T. spicata and the aqueous extract of S. thymbra possess the strongest anticoagulation effect as they increased both PT and aPTT values significantly relative to the control (p < 0.05). The variable anticoagulation bioactivity among the studied plant species could be referred to the various solvents degrees of solubility of different phyto-constituents. Thus, the efficacy of the plant species extracts evaluation as anticoagulants or coagulants were related to the plant species and to the solvent of extraction.

Abstract
High-efficiency particulate air supplied to a positive-pressure ventilation lobby (PPVL) in isolation rooms offers the dual advantage of protective and source isolation. This study demonstrates the in-use validity of PPVL rooms for protective isolation of patients. Of the 48 PPVL air samples investigated, Aspergillus fumigatus was detected from only one (2%) sample. Local and remote monitoring of the PPVL rooms is essential for the safety of patients and healthcare workers. Remote and point-of-use engineering controls are essential for ongoing ventilation monitoring, but this should be complemented by visual inspection of the isolation suite. Periodic microbiological monitoring should also be considered with other control measures.

Abstract
The molecular structure of the 2-(4-oxo-3-phenylthiazolidin-2-ylidene) malononitrile (3) is calculated using DFT B3LYP/6-311G(d, p) method. The calculated geometric parameters are in good agreement with the experimental data. The NBO calculations were performed to predict the natural atomic charges at the different atomic sites and study the different intramolecular charge transfer (ICT) interactions occurring in the studied system. The BD(2)C17-C19 → BD*(2)C14-C15, LP(2)O2 → BD*(1)N5-C9 and LP(1)N5 → BD*(2)C10-C11 ICT interactions causing stabilization of the system by 23.30, 30.63 and 52.48 kcal/mol, respectively. The two intense electronic transition bands observed experimentally at 249 nm and 296 nm are predicted using the TD-DFT calculations at 237.9 nm (f = 0.1618) and 276.4 nm (f = 0.3408), respectively. These electronic transitions are due to H-3 → L (94%) and H → L (95%) excitations, respectively.

Abstract
PURPOSE To evaluate the 2 year visual and anatomical results of intravitreal aflibercept injection (IAI) in nAMD in treatment-naive eyes in real life using a flexible regimen combining a PRN and modified treat-and-extend (TAE) regimen. PATIENTS AND METHODS This is a retrospective study including 48 eyes of 38 patients with nAMD treated with aflibercept as first line therapy. The modified T&E protocol consisted of a loading phase with 3 monthly IAI followed by an adaptation phase during which patients were monitored and treated as needed at the same visit from week 12 to week 32, then a T&E phase per se, for which the treatment interval was determined based on history of disease recurrence. RESULTS A total of 48 eyes were included. Visual acuity at baseline was 57.3±16 letters. Visual gain was 6±12 letters at 1 year and 5.2±11 letters at 2 years. At the 2-year end point, 94.3% of eyes maintained visual acuity and 71.4% of eyes had ≥70 letters. Reduction of central macular thickness, macular volume and pigment epithelium detachment height was observed after the loading phase, at 1 and 2 years compared to baseline. Complete resolution of fluid was obtained in 78% of eyes after the loading phase, in 68% of eyes at 1 year and in 62.8% of eyes at 2 years. Subfoveal choroidal thickness remained stable during the study. The surface area of the neovascular lesion was reduced at 1 year. The mean number of IAI was 6 IVT (3-11) during the first year and 3.2 IVT (0-13) during the second year. CONCLUSION Aflibercept is effective in real life in treatment-naive eyes at two years. A personalized regimen of IAI for neovascular AMD produced good functional and anatomical outcome over 2 years, with a lower number of injections than in the pivotal studies.
