Abstract
AIM To evaluate the long-term clinical effectiveness of computed tomography (CT)-guided transforaminal cervical epidural steroid injection using an anterolateral approach for the treatment of cervical radiculopathy (CR) using well-established robust clinical scoring systems for neck pain and neck disability. Despite its widespread use, evidence to support the long-term benefit of routine cervical epidural steroid injection is currently very limited. MATERIALS AND METHODS This study included 113 patients with magnetic resonance imaging (MRI)-confirmed CR who underwent a steroid injection at a single cervical level via a unilateral transforaminal anterolateral approach. Pain was assessed quantitatively at pre-injection, 15 minutes post-injection, 1 month, 3 months, and at 1 year. Neck disability was assessed using the Oswestry Neck Disability Index (NDI) at pre-injection, 1 month, 3 months, and 1 year time points. RESULTS Eighty patients completed the study. Sixty per cent reported reduced neck pain (mean pain reduction, 55%), which was clinically significant in 45% cases. Furthermore, 66% reported an improvement in neck disability (mean improvement, 51%), which was clinically significant for 56% patients. Clinically significant good outcomes in both neck pain and neck disability were evident from as early as 1-month, and importantly, were independent both of pre-treatment CR characteristics (including severity of pre-injection neck pain or disability) and of findings on pre-injection MRI imaging. CONCLUSION Transforaminal anterolateral approach CT-guided epidural steroid injection resulted in a clinically significant long-term improvement in both neck pain and disability for half of the present cohort of patients with unilateral single-level CR. This improvement was independent of the severity of the initial symptoms and pre-injection MRI findings.

Abstract
Diabetes mellitus shares a large proportion of kidney failure. Despite many patients suffering from diabetes mellitus and its complications in Dessie City, no study was conducted in the study area that shows the prevalence and associated factors of chronic kidney disease among diabetes mellitus patients. Therefore, this study aims to assess the prevalence of chronic kidney disease and its associated factors among adult diabetes mellitus patients attending Dessie Referral Hospital, South Wollo, Northeast Ethiopia. An institutional-based cross-sectional study was conducted at Dessie Referral Hospital among 267 randomly selected adult diabetic patients. Data were collected using questionnaires administered by interviewers. The glomerular filtration rate was estimated from serum creatinine levels. Data were entered into Epi-data version 4.6 and analyzed using SPSS version 26 software. Multi-variable logistic regression was used to determine the strength of association for the associated factors of chronic kidney disease. Variables with a p value < 0.05 were used to ascertain statistically significant associations. A total of 267 diabetic patients participated in this study. About 104 (39%) of the respondents were female and from the total, 133 (48.1%) were hypertensive. The overall prevalence of chronic kidney disease in this study was 31.5% (95% CI 25.3-37.1%). Being older (p-value = 0.003) and having hypertension (p-value = 0.043) were significant factors for chronic kidney disease among diabetes mellitus patients. This study found a high prevalence (31.5%) of chronic kidney disease among diabetic patients. Older age, having hypertension, and elevated serum creatinine were statistically significant associated factors of chronic kidney disease among patients with diabetes mellitus. Thus, clinicians should be aware of the high prevalence of chronic kidney disease in Dessie City. Moreover, emphasis should be given for old age and hypertension as contributing factors to the high prevalence in diabetic patients.

Abstract
BACKGROUND Global evaluations of the progress towards the WHO End TB Strategy 2020 interim milestones on mortality (35% reduction) and incidence (20% reduction) have not been age specific. We aimed to assess global, regional, and national-level burdens of and trends in tuberculosis and its risk factors across five separate age groups, from 1990 to 2021, and to report on age-specific progress between 2015 and 2020. METHODS We used the Global Burden of Diseases, Injuries, and Risk Factors Study 2021 (GBD 2021) analytical framework to compute age-specific tuberculosis mortality and incidence estimates for 204 countries and territories (1990-2021 inclusive). We quantified tuberculosis mortality among individuals without HIV co-infection using 22 603 site-years of vital registration data, 1718 site-years of verbal autopsy data, 825 site-years of sample-based vital registration data, 680 site-years of mortality surveillance data, and 9 site-years of minimally invasive tissue sample (MITS) diagnoses data as inputs into the Cause of Death Ensemble modelling platform. Age-specific HIV and tuberculosis deaths were established with a population attributable fraction approach. We analysed all available population-based data sources, including prevalence surveys, annual case notifications, tuberculin surveys, and tuberculosis mortality, in DisMod-MR 2.1 to produce internally consistent age-specific estimates of tuberculosis incidence, prevalence, and mortality. We also estimated age-specific tuberculosis mortality without HIV co-infection that is attributable to the independent and combined effects of three risk factors (smoking, alcohol use, and diabetes). As a secondary analysis, we examined the potential impact of the COVID-19 pandemic on tuberculosis mortality without HIV co-infection by comparing expected tuberculosis deaths, modelled with trends in tuberculosis deaths from 2015 to 2019 in vital registration data, with observed tuberculosis deaths in 2020 and 2021 for countries with available cause-specific mortality data. FINDINGS We estimated 9·40 million (95% uncertainty interval [UI] 8·36 to 10·5) tuberculosis incident cases and 1·35 million (1·23 to 1·52) deaths due to tuberculosis in 2021. At the global level, the all-age tuberculosis incidence rate declined by 6·26% (5·27 to 7·25) between 2015 and 2020 (the WHO End TB strategy evaluation period). 15 of 204 countries achieved a 20% decrease in all-age tuberculosis incidence between 2015 and 2020, eight of which were in western sub-Saharan Africa. When stratified by age, global tuberculosis incidence rates decreased by 16·5% (14·8 to 18·4) in children younger than 5 years, 16·2% (14·2 to 17·9) in those aged 5-14 years, 6·29% (5·05 to 7·70) in those aged 15-49 years, 5·72% (4·02 to 7·39) in those aged 50-69 years, and 8·48% (6·74 to 10·4) in those aged 70 years and older, from 2015 to 2020. Global tuberculosis deaths decreased by 11·9% (5·77 to 17·0) from 2015 to 2020. 17 countries attained a 35% reduction in deaths due to tuberculosis between 2015 and 2020, most of which were in eastern Europe (six countries) and central Europe (four countries). There was variable progress by age: a 35·3% (26·7 to 41·7) decrease in tuberculosis deaths in children younger than 5 years, a 29·5% (25·5 to 34·1) decrease in those aged 5-14 years, a 15·2% (10·0 to 20·2) decrease in those aged 15-49 years, a 7·97% (0·472 to 14·1) decrease in those aged 50-69 years, and a 3·29% (-5·56 to 9·07) decrease in those aged 70 years and older. Removing the combined effects of the three attributable risk factors would have reduced the number of all-age tuberculosis deaths from 1·39 million (1·28 to 1·54) to 1·00 million (0·703 to 1·23) in 2020, representing a 36·5% (21·5 to 54·8) reduction in tuberculosis deaths compared to those observed in 2015. 41 countries were included in our analysis of the impact of the COVID-19 pandemic on tuberculosis deaths without HIV co-infection in 2020, and 20 countries were included in the analysis for 2021. In 2020, 50 900 (95% CI 49 700 to 52 400) deaths were expected across all ages, compared to an observed 45 500 deaths, corresponding to 5340 (4070 to 6920) fewer deaths; in 2021, 39 600 (38 300 to 41 100) deaths were expected across all ages compared to an observed 39 000 deaths, corresponding to 657 (-713 to 2180) fewer deaths. INTERPRETATION Despite accelerated progress in reducing the global burden of tuberculosis in the past decade, the world did not attain the first interim milestones of the WHO End TB Strategy in 2020. The pace of decline has been unequal with respect to age, with older adults (ie, those aged >50 years) having the slowest progress. As countries refine their national tuberculosis programmes and recalibrate for achieving the 2035 targets, they could consider learning from the strategies of countries that achieved the 2020 milestones, as well as consider targeted interventions to improve outcomes in older age groups.

Abstract
OBJECTIVE One of the major concerns of the post-COVID-19 era is elucidating and addressing the long-term complications of COVID-19. SUBJECTS AND METHODS A web-based questionnaire was distributed in Jordan to assess the prevalence and recovery from chemosensory dysfunction among COVID-19 long-haulers in Jordan. RESULTS A total of 611 respondents complained of chemosensory dysfunction (age range = 18-68 years), and the majority of the respondents were female (88.4%). Parosmia was the most prevalent olfactory dysfunction reported (n = 337, 33.3%), and parageusia was the most frequently reported gustatory dysfunction (n = 239, 36.4%). Medications were not reported to be associated with a better perception of smell or taste by nearly half of those who had been treated (n = 146, 46.1%). Among participants who had received olfactory rehabilitation/training (n = 215, 35.2%), 43.7% (n = 94) reported modest improvement, with the most frequently helpful scents being coffee (n = 80, 24.8%), aromatic oils (n = 74, 23%), and perfumes/colognes (n = 73, 22.7%). Age was found to have a significant negative correlation with complete recovery. In addition, age (p < .05), anosmia (p < .001), hyperosmia (p < .001), ageusia (p < .05), and duration of olfactory dysfunction (p < .001) were all independent predictors of complete recovery. CONCLUSIONS Chemosensory dysfunctions are largely subjective; therefore, more objective examinations are required to draw more definite conclusions.

Abstract
Larvae of European rose chafer Cetonia aurata (Linnaeus, 1758) and cockchafer Melolontha sp. beetles were collected in Hungary for parasitological study. Intestinal examination revealed the presence of three well-known thelastomatid nematodes belonging to the genus Cephalobellus Cobb, 1920. We report for the first-time Cephalobellus cuspidatum (Rudolphi, 1814) Leibersperger, 1960, C. osmodermae Leibersperger, 1960, and C. potosiae Leibersperger, 1960 in Hungary, all found in scarab beetle larvae. Due to incomplete original descriptions, a comprehensive redescription with detailed morphological data is presented. Additionally, an identification key for closely related Cephalobellus, Thelastoma and Severianoia species infesting scarab beetles worldwide is provided. Newly generated 18S and 28S rDNA gene sequences of C. osmodermae place it as one of the early branches within Thelastomatidae.

Abstract
Numerous studies have shown a correlation between dengue virus (DENV) infection and kidney disease. However, there is no existing meta-analysis on the prevalence of kidney diseases in the dengue population. A thorough systematic review and meta-analysis were undertaken to determine the prevalence of renal problems in people with DENV infection in order to fill this knowledge gap. A rigorous electronic literature search was carried out up to 25 January 2023 in a number of databases, including ProQuest, EBSCOhost, Scopus, PubMed and Web of Science. The search aimed to find articles that reported on the prevalence of kidney diseases in patients with DENV infection. Using the modified Newcastle-Ottawa Scale, the quality of the included studies was assessed. The meta-analysis included a total of 37 studies with 21 764 participants reporting on the prevalence of acute kidney injury (AKI) in individuals with DENV infection. The pooled prevalence of AKI in dengue patients was found to be 8% (95% confidence interval 6 to 11), with high heterogeneity across studies. The studies included are of moderate quality. The study revealed a high AKI prevalence in dengue patients, underlining the need for regular renal examination to detect AKI early and reduce hospitalization risk. Further research is needed to understand the dengue-kidney relationship and develop effective management strategies.

Abstract
Efficient Neural Architecture Search (ENAS) is a recent development in searching for optimal cell structures for Convolutional Neural Network (CNN) design. It has been successfully used in various applications including ultrasound image classification for breast lesions. However, the existing ENAS approach only optimizes cell structures rather than the whole CNN architecture nor its trainable hyperparameters. This paper presents a novel framework for automatic design of CNN architectures by combining strengths of ENAS and Bayesian Optimization in two-folds. Firstly, we use ENAS to search for optimal normal and reduction cells. Secondly, with the optimal cells and a suitable hyperparameter search space, we adopt Bayesian Optimization to find the optimal depth of the network and optimal configuration of the trainable hyperparameters. To test the validity of the proposed framework, a dataset of 1522 breast lesion ultrasound images is used for the searching and modeling. We then evaluate the robustness of the proposed approach by testing the optimized CNN model on three external datasets consisting of 727 benign and 506 malignant lesion images. We further compare the CNN model with the default ENAS-based CNN model, and then with CNN models based on the state-of-the-art architectures. The results (error rate of no more than 20.6% on internal tests and 17.3% on average of external tests) show that the proposed framework generates robust and light CNN models.

Abstract
Abstract Production of transgenic plants with desired agronomic and horticultural traits has gained great importance to fulfill demands of the growing population. Genetic transformation is also a fundamental step to study basics of plant sciences. Different transformation protocols have been developed and used which are reliable and efficient. These protocols used antibiotic or herbicide resistance genes incorporated along with gene of interest to identify transformed plants from non-transformed ones. These marker genes may pose a threat to human and environment. Use of visual markers enables direct and easier observation of transformed plants with more precision. In current study a gene cassette with ‘pigment production hydroxylase (PPH) gene under fiber specific promoter (GhSCFP) and downstream Nos-terminator was designed. After checking the structural and functional efficiency of codon optimized gene using bioinformatics tools, the cassette was sent for chemical synthesis from commercial source. The pigment gene cassette (PPH_CEMB), cloned in pCAMBIA-1301, was transformed into Agrobacterium through electroporation. Agrobacterium-mediated floral dip method was used to transform Camelina sativa inflorescence. After seed setting a total of 600 seed were observed for change in color and out of these, 19 seeds developed a reddish-brown coloration, while the remaining 581 seeds remained yellow. The transformation efficiency calculated on basis of color change was 1.0%. PCR analysis of leaves obtained after sowing reddish seeds confirmed the transformation of pigment production gene, while no PCR amplification was observed in leaves of plants from wild type seeds. From the results it is evident that Agrobacterium-mediated transformation of C. sativa inflorescence is very efficient and environment friendly technique not only for detection of transformed plants but also to study basic cellular processes.

Abstract
This cross-sectional descriptive purposive study was done on 150 (70 right and 80 left) fully ossified dry human scapulae of Bangladeshi people to find out the variation in length of acromiocoracoid and acromioglenoid distance. Sample collection was carried out in the Department of Anatomy, Mymensingh Medical College, Bangladesh from January to December 2019. Any kind of damaged or broken scapulae were excluded to maintain standard measurement. Length of these distances was measured with the help of digital Vernier slide calipers. The mean±SD acromiocoracoid distance were 35.8±4.64 mm and 36.32±5.55 mm on right and left sided scapulae respectively and the mean±SD acromioglenoid distance were 27.69±3.43 mm on right sided scapulae and 28.18±3.26 mm on left sided scapulae. These data are important to compare Bangladeshi scapulae to those from various other races that could contribute to demographic studies of shoulder disease probability and management in Bangladeshi population.

Abstract
Introduction People without reliable access to healthcare are more likely to be diagnosed with late-stage cancer that could have been treated more effectively if diagnosed earlier. Emergency departments (ED) may be a novel place for cancer screening education for underserved patients. In this study we sought to determine patient characteristics and barriers to cancer screening for those patients who presented to a large, academic safety-net ED and were overdue for breast, cervical, and colorectal cancer screening since the coronavirus 2019 (COVID-19) pandemic. Methods Adult ED patients eligible for at least one cancer screening based on US Preventive Serivces Task Force guidelines completed a web-based survey. We examined the association of demographic characteristics and having a personal physician with being overdue on screening using chi-square or the Fisher exact test for categorical variables and t-tests for continuous variables. Results Of 221 participants, 144 were eligible for colorectal, 96 for cervical, and 55 for breast cancer screening. Of eligible patients, 46% (25/55) were overdue for breast cancer screening, 43% (62/144) for colorectal, and 40% (38/96) for cervical cancer screening. There were no significant characteristics associated with breast cancer screening. Being overdue for cervical cancer screening was significantly more likely for patients who were of Asian race (P = 0.02), had less than a high school diploma (P = 0.01), and were without a routine checkup within the prior five years (P = 0.01). Overdue for colorectal cancer screening was associated with patients not having insurance (P = 0.04), being in their 40s (P = 0.03), being Hispanic (P = 0.01), and not having a primary care physician (P=0.01). Of 97 patients overdue for at least one screening, the most common barriers were cost (37%), lack of time (37%), and lack of knowledge of screening recommendations (34%). Only 8.3% reported that the COVID-19 pandemic delayed their screening. Conclusion The ED may be a novel setting to target patients for cancer screening education. Future work that refers patients to free screening programs and primary care physicians may help improve disparities in cancer screening and cancer mortality rates for underserved populations.

Abstract
A cross-sectional study was conducted from March 2019 to August 2019 to determine the pattern of work-related respiratory problems among workers in ship breaking industry at Sitakunda, Chittagong, Bangladesh as many unskilled and semiskilled worker are working there without having minimum knowledge and idea about the possible adverse health effect of different pollutants which also pose threats to the ambient environment. Total 120 male respondents were selected purposively. Majority 80.8% (97) of the workers were below 30 years. About 71.0% (85) respondents were working for less than five years. Majority of respondents worked 8 hours daily. Most of them worked each of the days in a week. About 66.0% (80) had smoking habit. Among 120 respondents, 95.8% (115) had no previous respiratory problem. But 63.3% (76) felt that their respiratory problems were increasing day by day due to current job (ship breaking). There were 85.0% (102) respondents who felt cold or sneeze mostly in working place. About 80.0% (96) of respondents felt better during holiday. There were different respiratory symptoms among the respondents like nasal irritation, hoarseness of voice, cough during cold, cough without cold, bringing up phlegm when catch cold, bringing up phlegm without cold, tightness of chest where the prevalence was 54.2% (65), 85.0% (102), 93.3% (112), 28.3% (34), 70.0% (84), 39.0% (27) and 67.5% (81) respectively among the workers. Majority respondents 96.7% (116) were conscious about using PPE. Only 17.5% (21) used mask during work. Different pulmonary lung function test like forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1%, peak expiratory flow rate (PFER) was done. Mean of FVC, FEV1 was 3.76 and 1.09 respectively. According to pulmonary statuses of workers as per spirometric findings 20.83% (25) had normal pulmonary function, 58.33% (45) had obstruction and 20.83% (25) had combined obstructive parameters. So in light of the study it is clear that the work organization has not developed in this particular industry. In every steps of their work ship breaking workers are facing violations of industrial codes which correspond with safe working environment. In long run the workers have to pay with their health and life about which they are unaware.

Abstract
AIMS Phyllodes tumours and breast sarcomas are uncommon tumours and their rarity poses significant challenges in diagnosis and management. This cross-sectional study was conducted to evaluate the multidisciplinary clinical practice for these tumours across the UK and Ireland, with the aim of identifying gaps in knowledge and providing direction for establishing national guidelines. MATERIALS AND METHODS An international survey was adapted and circulated to breast and/or sarcoma surgeons and oncologists in the UK and Ireland through national organisations. Multidisciplinary team (MDT) responses were analysed anonymously. RESULTS Twenty-eight MDTs participated in this study, predominately from high-volume units (85.5%). Although only 43% of the surveyed units were part of a trust that holds a sarcoma MDT, 68% of units managed malignant phyllodes and angiosarcoma, whereas 64.5% managed soft-tissue sarcoma of the breast. Across all subtypes, axillary surgery was recommended by 14-21% of the MDTs and the most recommended resection margins for breast surgery were 'no tumour on ink' in benign phyllodes (39%) and 10 mm in the remaining subtypes (25-29%). Immediate breast reconstruction was supported by 11-18% of MDTs for breast sarcoma subtypes, whereas 36% and 32% advocated this approach in benign and borderline phyllodes tumours, respectively. Adjuvant radiotherapy and chemotherapy were recommended by up to 29% and 11% of the MDTs, respectively. CONCLUSION The results of this study demonstrate a wide variation in clinical practice across the surveyed MDTs. As only 28 MDTs participated in our study, with under-representation from low-volume units, our results might be an underestimation of the variability in practice across the UK and Ireland. This multi-institutional study sheds light on controversial aspects in the management of phyllodes tumours and breast sarcoma, identifies the need for national guidelines to inform best practice, and calls for the centralisation of the management of breast sarcoma within specialist centres.

Abstract
The nutrient foramen is the natural opening present in the shaft of the humerus. It passes the nutrient artery to the medullary cavity. The nutrient artery is the chief artery that enters the bone through a nutrient foramen to provide nutrition for its growth. It plays an important role in healing during fracture and trauma and is also important for bone grafting. This study aimed to determine the common location, position and number of nutrient foramina of fully ossified dry human humerus. One hundred samples (right- 43 and left- 57) were selected through the purposive sampling technique for this cross-sectional descriptive study carried out in the Department of Anatomy, Mymensingh Medical College, Bangladesh from July 2021 to June 2022. Any damaged, unossified bones or fractured bones were excluded. Data were tabulated and statistically analyzed using Microsoft Excel and SPSS software. Among 43 right humeri, 37(75.51%) have single-nutrient foramen and 06(24.49%) have double-nutrient foramina. Among 57 left humeri, 53(92.98%) have single nutrient foramen, 03(5.27%) have double nutrient foramina and 01(1.75%) has triple nutrient foramina. In case of location of nutrient foramina, among 49 right nutrient foramina, 45(91.84%) were found on the anteromedial surface, 02(4.08%) were found on the anterolateral surface and 02(4.08%) were on the posterior surface of the shaft of the humerus. In case of 62 left nutrient foramina, 57(91.94%) were found on the anteromedial surface and 05(8.06%) were found on the posterior surface of the shaft of the humerus. Among 49 right nutrient foramina, 01(2.04%) was found on the upper third, 46(93.88%) on the middle third and 02(4.08%) on the lower third of the shaft of the humerus. In case of 62 left nutrient foramina, 01(1.60%) was on the upper third, 57(91.95%) were on the middle third and 04(6.45%) were on the lower third of the shaft of the humerus.

Abstract
PURPOSE Derogenes ruber Lühe, 1900, the type-species of the genus Derogenes Lühe, 1900, is a poorly known derogenid digenean. The original description of this species was not illustrated and aspects of the morphology of the parasite from the type-host remain scarce. Available records of this species were brief and/or lacked illustrations and were based on morphology alone. Additionally, molecular data for Derogenes spp. are warranted to untangle species complexes as they provide a better assessment of interspecific genetic divergence. METHODS Derogenes ruber is redescribed based on newly collected specimens from the gall bladder of its type-host Chelidonichthys lastoviza (Bonnaterre, 1788) collected in the Western Mediterranean off the Algerian coast during 2017-2019 and molecular data are provided using a partial fragment of the nuclear 28S ribosomal RNA gene (28S rRNA), the internal transcribed spacer 2 (ITS2) and a fragment of the mitochondrial cytochrome c oxidase subunit 1 (cox1) gene. RESULTS We herein provide a detailed illustrated redescription and morphometric data of D. ruber from its type-host C. lastoviza. We report a new geographical record (off Algeria) for it. Derogenes ruber is also genetically characterised for the first time. Species/lineages of Derogenes were recovered in five strongly supported reciprocally monophyletic clades: (i) D. ruber from C. lastoviza off Algeria; (ii) D. lacustris from Galaxias maculatus (Jenyns) off Argentina; (iii) Lineage "D. varicus DV1" (D. varicus sensu stricto) from fish hosts in the White and Barents seas and the North Sea; (iv) Lineage "D. varicus DV2" from mollusc hosts in the White Sea; and (v) Lineage "D. varicus DV3" from Eumicrotremus fedorovi Mandrytsa. in the Pacific Ocean. Hence, comparison of the newly generated sequences with other available data for Derogenes species supports the distinction of D. ruber confirming its taxonomic status and helping assess interspecific variation. Comparison of D. ruber with the closely related species Derogenes latus revealed overlaps in morphometric data and the validity of the latter species is questioned. CONCLUSION The combination of morphological and molecular data provided for D. ruber provides a firm foundation for further investigations of Derogenes spp. Although we do describe herein material of D. ruber from the type-host, given that the occurrence of a single Derogenes species in various hosts has been challenged by molecular data, and both D. lacustris and D. varicus sensu stricto had been genetically proven to occur in various hosts, D. ruber and D. latus may be indeed synonymous. Additional sequencing effort on Derogenes spp. will strengthen systematic comparative studies and evolutionary relationships within the Derogenidae in general.

Abstract
Maintaining genomic stability is crucial for normal development. At earlier stages of preimplantation development, as the embryonic genome activation is not fully completed, the embryos may be more prone to abnormalities. Aneuploidies are one of the most common genetic causes of implantation failure or first-trimester miscarriages. Apoptosis is a crucial mechanism to eliminate damaged or abnormal cells from the organism to enable healthy growth. Therefore, this study aimed to determine the relationship between the expression levels of genes involved in apoptosis in human aneuploid and euploid blastocysts. In total, 32 human embryos obtained from 21 patients were used for this study. Trophectoderm biopsies were performed and next-generation screening was carried out for aneuploidy screening. Total RNA was extracted from each blastocyst separately and cDNA was synthesized. Gene expression levels were evaluated using RT-PCR. The statistical analysis was performed to evaluate the gene expression level variations in the euploid and aneuploid embryos, respectively. The expression level of the BAX gene was significantly different between the aneuploid and euploid samples. BAX expression levels were found to be 1.5-fold lower in aneuploid cells. However, the expression levels of BAK and MAD2L1 genes were similar in each group. This study aimed to investigate the possible role of genes involved in apoptosis and aneuploidy mechanisms. The findings of this investigation revealed that the BAX gene was expressed significantly differently between aneuploid and euploid embryos. Therefore, it is possible that the genes involved in the apoptotic pathway have a role in the aneuploidy mechanism.

Incomplete original descriptions, the unavailability or poor conditions of specimens and the lack of detailed redescriptions have caused the validity of several species of the genus Encotyllabe Diesing, 1850 to be questioned. To date, seven of the recognized species were described upon one or two specimens, hindering study of intraspecific variations. This was made worse by considering few morphoanatomical differences sufficient to erect new species. Among Encotyllabe spp. occurring in Mediterranean waters, E. vallei was first described from the gilt-head bream Sparus aurata (Sparidae) off Italy. Although beautifully illustrated for a paper from that century, morphometric data for E. vallei from the type-host S. aurata remain unavailable. Previous records of E. vallei provided either morphometrical or molecular data, and its validity was questioned. We provide a redescription of E. vallei based on newly collected specimens from the S. aurata from the southwestern Mediterranean (off Algeria) using integrative taxonomy. Analysis of cox1 sequences of E. vallei from S. aurata, compared to sequences from other sparid hosts, mainly Pagellus bogaraveo, revealed a divergence not exceeding 2%, suggesting a stenoxenic specificity for this monogenean. Given that P. bogaraveo is the type-host for Encotyllabe pagelli, we were tempted to suggest a synonymy between E. vallei and E. pagelli. We refrained from doing so because E. pagelli was first described from the Atlantic coast off Brest, France. Morphological data for Encotyllabe from P. bogaraveo are warranted assessing the host specificity of E. vallei and whether there might be a species complex within individual sparid fish species.

Abstract
Background Coronaviruses, known for their crown-like appearance, cause mild gastrointestinal and respiratory diseases. Some cause outbreaks of respiratory diseases, most recently, SARS-CoV-2, the coronavirus disease 2019 (COVID-19). Individuals with COVID-19 are reported to be in both arterial and venous prothrombotic states. In addition to a lipid-lowering effect, statin also has an anti-inflammatory effect, which addresses one of the underlying causes of thrombosis. An in-silico study revealed that statins could directly interact with the main protease enzyme of SARS-CoV-2 and prevent infectivity. Due to these pleiotropic properties, statins may positively impact the outcome of hospitalized patients with COVID-19 infections. Methods A total of 26 445 acute COVID-19-infected patients were included in this study. Patients were stratified based on home statin use status: no statins, high-intensity statins (atorvastatin 40-80 mg daily and rosuvastatin 20-40 mg daily), and low-to-moderate intensity statins (all other statins). A multivariate generalized linear model and logistic regression were used to predict the hospital length of stay and inpatient mortality, respectively. Results The hospital length of stay was compared between low-intensity and high-intensity statin use against no statin therapy. The length of stay was 3.88 days (95% CI, 3.56-4.20; P < .0001) longer among patients with low-dose statin therapy compared to patients without. The length of stay was 4.77 days (95% CI, 4.42-5.13; P <.0001) longer among patients with high-intensity statin therapy than those without. The odds of in-hospital mortality decreased by 24% (OR, 0.76; 95% CI, 0.76-0.97) among those with high-dose statin therapy compared to patients without (P = .02). There was no statistical significance between the low-dose statin group and the no statin group for inpatient mortality. Conclusion Hospitalized COVID-19 patients on statin therapy, regardless of intensity, are more likely to have a longer length of stay. There may be a mortality benefit in using high-intensity statin in acute COVID-19-infected patients. The results of this study are insufficient to recommend statin therapy for inpatient COVID-19 treatment. However, patients with significant cardiovascular comorbidities, where statins are indicated, should be on these medications, especially amidst the COVID-19 pandemic. Randomized controlled trials are needed to assess the potential in-hospital benefit of statin therapy on COVID-19 patients.

Abstract
PURPOSE/OBJECTIVE(S) The purpose of this study was to introduce a new commercial electron FLASH system that has the potential to become widely available for FLASH researchers globally. In this study, we first present the initial acceptance and commissioning tests for the FLASH system, and second, we highlight preliminary FLASH effect results from our cell studies. MATERIALS/METHODS A linear accelerator was converted into a commercial research platform with the FLASH Research Extension, enabling the generation of a powerful 16 MeV electron FLASH beam. The dosimetric and stability tests were conducted using various dosimeters (i.e., radiochromic film, optically stimulated luminescent dosimeters (OSLDs), and a plane-parallel ionization chamber). To evaluate the FLASH effect, normal and cancer cell lines were FLASH irradiated using different pulse repetition frequencies (PRF) of 18 pulses/s and 180 pulses/s. RESULTS The electron FLASH mode was able to generate over 1 Gy per pulse at the isocenter and a dose rate of up to 690 Gy/s near the accessory mount of the Linac gantry head. The charge collected by the plane-parallel ionization chamber at the highest PRF (i.e., 180 pulses/s) showed a linear relationship with the delivered number of pulses (i.e., 1 to 99 pulses) with a coefficient of determination (R2) of 0.9996. The absorbed dose measured using radiochromic film and OSLDs agreed within 3%, on average, and followed an inverse square law as the source-to-axis distance (SAD) varied for which the R2 values were 0.9972 and 0.9955 for radiochromic film and OSLDs, respectively. The profile of the FLASH beam was symmetrical but was not as flat as the conventional 16 MeV electron beam due to the use of a thinner custom scattering foil to reduce the degradation of the ultra-high dose rate. The depth-dose curve beyond the build-up region for the FLASH beam was similar to the conventional 16 MeV electron beam for which the range at 50% the maximum dose (R50) agreed within 0.5 mm. The FLASH beam output remained consistent over a 4-month period with a variation of 2.5%, on average. The FLASH sparing effect was observed in vitro for healthy human pancreatic cells. Furthermore, we observed that the highest PRF beam (180 pulses/s) was more effective at destroying pancreatic cancerous cells while minimizing damage to healthy cells compared to the lowest PRF beam (18 pulses/s). CONCLUSION The novel commercial FLASH Research Extension system was dosimetrically characterized for pre-clinical FLASH research, and preliminary in vitro results demonstrated the FLASH effect. Given the prevalence of linear accelerators, this new commercial system has the potential to greatly increase the access to FLASH research.

Abstract
PURPOSE/OBJECTIVE(S) SFRT has shown promise as a treatment modality to decrease normal tissue sparing without compromising tumor coverage, i.e., an increase in the therapeutic window compared to more conventional uniform radiation therapy (RT). The aim of this work is to examine and test several alternative bio-dosimetric parameters for the prediction of cell survival for normal-tissue and tumor cell lines irradiated in vitro with uniform and microbeam radiotherapy (MRT). MATERIALS/METHODS A bespoke tungsten collimator with 50 parallel, 50 µm wide slits and 400 µm slit spacing was mounted into an x-ray cabinet. Human fibroblast (MRC5) and two human tumor cell lines (LN18 and A549) were irradiated with a range of doses (< 10 Gy) for uniform and MRT (50um slits, 400um center spacing) using kV X-rays. Average, mean and valley dose as useful predictive metrics of cell survival are compared to the equivalent uniform dose (EUD) with biological parameters estimated from uniform-dose experiments. RESULTS We find that EUD, with linear-quadratic (LQ) model parameters, is more predictive for survival after SFRT than maximum, minimum or average dose. The maximum and average doses are correlated very poorly with in vitro cell survival. The difference in cell survival between uniform and MRT irradiation as a function of EUD is cell-type and dose dependent. The report results suggest that MRT is more effective at cell killing of tumor-cell lines than uniform irradiation for both tumor cell lines. However, MRT is less effective at killing normal tissue cells than uniform irradiation. CONCLUSION EUD is a superior predictor of in vitro cell survival than other metrics sometimes used in the SFRT literature, including mean dose, maximum dose, and valley dose. The reported studies provide some evidence that SFRT may increase the therapeutic ratio by producing spatial dose distributions that effectively reduce normal-tissue damage with little or no change in biological damage to tumor cells. Additional studies are needed to further extend and generalize our results and to test our conclusions against a larger dose range, low and high linear energy transfer (LET) radiations and additional cell lines.

Abstract
Derogenes varicus (Müller, 1784) is widely reported as a trematode with exceptionally low host specificity and a wide, bipolar distribution. However, several recent studies have suggested that D. varicus represents a species complex and based on molecular evidence, four genetic lineages (labeled as "DV1-4") have been designated within the D. varicus species complex. This possibility requires improved (ideally molecular) characterisation of specimens from the type-host (Salmo salar) and type-locality (off Denmark). During examination of trematode parasites of fish from Scandinavian and Arctic waters (Sweden and Norway), we found specimens of D. varicus in the stomach of Merlangius merlangus off the coast of Sweden, and in Gadus morhua off the coast of Sweden and Norway; we compared them to D. varicus from the type-host, the Atlantic salmon Salmo salar from Norway, to verify their conspecificity. Newly generated sequences (28S rDNA, ITS2 and cox1) of Scandinavian and Arctic specimens consistent with D. varicus all formed a single clade, DV1. 28S sequences of D. varicus from S. salar from Norway, i.e., close to the Danish type locality, clustered within the DV1 clade along with sequences of D. varicus from various hosts including Limanda limanda, G. morhua and Myoxocephalus scorpius from the White Sea and the Barents Sea (Russia), without any host-related structuring. We thus consider that the lineage DV1 represents D. varicus sensu stricto. Additionally, specimens from M. merlangus had a similar morphology and anatomy to those of D. varicus from L. limanda, G. morhua and M. scorpius from T. Odhner's collection, supporting the presence of a single species in the DV1 lineage designated herein as D. varicus sensu stricto. We redescribe D. varicus sensu stricto, add new morphological characters and provide morphometric data. We infer that D. varicus types DV2-4 all relate to separate species. We also revise type-specimens of Derogenes minor Looss, 1901 from the A. Looss collection in the Swedish Museum of Natural History and provide redescriptions of it and of the type-species of the genus, Derogenes ruber Lühe, 1900. In light of their morphological distinctiveness relative to D. varicus sensu stricto, we reinstate D. parvus Szidat, 1950 and D. fuhrmanni Mola, 1912.

Abstract
BACKGROUND Good attitude towards to time management is the backbone to bring a change at individual and organizational levels in different sectors across the globe. But it has been ignored by different institutions, particularly in low and middle-income countries including Ethiopia. However, this can be alleviated if there are punctual, committed, and accessible health professionals that could translate the national aspirations and the desire of the community into reality. This study aims to determine the magnitude and associated factors of attitude towards time management among health professionals working in public hospitals of Dessie City, Northeast Ethiopia, METHODS: Institution-based cross-sectional study was conducted from March 24 -April 24, 2021 among 409 health professionals using a stratified sampling technique, Frequency and percentage were used to describe the study population. Multivariable logistic regression analysis was used to identify independent predictors. A p-value of < 0.05 with 95% CI were used to declare statistically significant associations. RESULTS The overall good time management attitude among sample was 67%(95%CI:66.77-67.22%). Satisfaction with organizational policy and strategy (AOR: 2.69, 95%CI: 1.42-5.09), satisfaction with supervisor support (AOR: 2.12, 95% CI: 1.19-3.77), and managers' good attitude towards time management (AOR: 2.00, 95%CI: 1.23-3.25) were significantly associated with good attitude towards time management among health professionals. CONCLUSION The attitude towards time management in public hospitals of Dessie City was low. Satisfaction with organizational policies and strategies, satisfaction with supervisor support, and managers' good attitude towards time management were delineated factors. This low attitude towards time management could affect the practice and it compromise the health service coverage and quality unless timely and appropriate interventions should be taken. Strengthening strategies aimed at maximizing job satisfaction and emphasizing an attitude towards time might have a substantial contribution.

Abstract
INTRODUCTION Diversity in the healthcare workforce is associated with improved performance and patient-reported outcomes. Gender disparity in Trauma and Orthopaedics (T&O) is well recognised. The aim of this study was to compare factors that influence career choice in T&O between male and female final-year students. Furthermore, the trend of representation of women in T&O over the last decade was also compared with other surgical specialities. METHODS An online survey of final-year students who attended nationally advertised T&O courses over a 2-year period was conducted. Data from NHS digital was obtained to assess gender diversity in T&O compared with other surgical specialities. RESULTS A total of 414 students from 13 UK medical schools completed the questionnaire. Compared with male students (34.2%), a significantly higher proportion of women (65.8%) decided against a career in T&O, p<0.001. Factors that dissuaded a significantly higher percentage of women included gender bias, technical aspects of surgery, unsociable hours, on-call commitments, inadequate undergraduate training and interest in another specialty (p<0.05). Motivating factors for choosing a career in T&O were similar between both sexes. T&O was the surgical specialty with the lowest proportion of women at both consultant and trainee level over the last decade. CONCLUSION T&O remains an unpopular career choice among women. To enhance recruitment of women in T&O, future strategies should be directed toward medical students. Universities, orthopaedic departments and societies must work collaboratively to embed culture change, improve the delivery of the undergraduate curriculum, and facilitate students' exposure to operating theatres and female role models.

Abstract
OBJECTIVES This study aimed to analyze the incidence, surgical management of major vascular complications, and outcomes in patients undergoing transfemoral (TF) transcatheter aortic valve replacement (TAVR) at our center after strict selection of the access route, carefully considering all known major predictors. METHODS Data of 494 consecutive patients with pre-interventional multi-slice computed tomography (CT) of the aorta who had undergone TF TAVR from 2009 to 2019 were analyzed. RESULTS In total, 23/494 (4.7%) patients had major vascular and access-related complications of peripheral vessels and/or infrarenal aorta. These included hematomas that met the Valve Academic Research Consortium 3-criteria of major vascular complications (7/494, 1.4%), arterial dissections (3/494, 0.6%), pseudoaneurysm (6/494, 1.2%), thrombus of the external iliac artery leading to acute limb ischemia (1/494, 0.2%), fistula (1/494, 0.2%), and perforation (5/494, 1.0%). In total, 17/23 (73.9%) major vascular complications required immediate endovascular and/or open surgery. In 16/17 (94%) cases, only 1 surgical procedure was performed. The long-term survival of patients with and without major vascular complications of the peripheral vessels was determined after 2 years. CONCLUSIONS Early vascular surgery intervention reversed the mortality disadvantage in patients with major complications of the peripheral vessels after TAVR. This underscores the importance of immediate vascular surgery stand-by as an indispensable requirement.

Abstract
BACKGROUND There is a disparity in the provision of quality and safe surgical care in Nigeria. The capacity to track surgical safety through the use of the surgical safety checklist tool is variable in this setting. This study aimed to assess the outcomes of training on this checklist and the results of its pilot implementation. SUBJECTS, MATERIALS AND METHODS A mixed-methods research comprising of quantitative and qualitative study designs was conducted to evaluate these 23 weeks intervention in our centre. Implementation was conducted in two phases: training of the surgical team and pilot testing of the intervention. Using the RE-AIM framework, implementation outcomes evaluated included reach of training, adoption of checklist and implementation challenges, while effectiveness outcomes evaluated included change in the knowledge score after the training and self-reported impact of the training and pilot test. Quantitative and qualitative data were collected and analyzed. RESULTS There was a 2.4-point significant increase in the knowledge score after the training. During the pilot testing phase, 843 patients had surgery. The weekly checklist utilization rate for elective surgery rose to 64% at project completion. Despite logistic and manpower-related implementation challenges, the training intervention facilitated the translation of participant knowledge into practice (81.5%) and the pilot phase had a high impact on the practice of checklist use (3.8 ± 0.9). CONCLUSION The quality improvement programme enhanced knowledge of checklist use and led to improved behaviour and positive organizational change. However, barriers need to be addressed to strengthen the sustainable use of the checklist tool.

Abstract
Multiple Sclerosis (MS) is a debilitating disease that affects millions of people worldwide. In this study, we aimed to shed light on the clinical and epidemiological characteristics of MS in Ninevah governorate, Iraq. Our goal was to provide valuable insights into the disease's prevalence, symptoms, and functional disability among Iraqi patients. The present case-series study was conducted on 418 patients diagnosed with MS based on McDonald criteria. Kurtzke Expanded Disability Status Score (EDSS) used for patients' assessment. The prevalence of MS in Ninevah governorate is predicted to be 10.3 per 100,000, with an annual incidence ranging from 4.6 to 11.57 per million in the last four years. The average age of symptom onset was 27.7±9.9 years, with an average symptom duration of 7.2±6.9 years. Women were twice as likely to be diagnosed with MS, with a female-male ratio of 1:0.6. Sensory symptoms were more common than visual and motor symptoms. The most common subtype of clinical presentation was relapsing-remitting MS, followed by secondary progressive MS and primary progressive MS. Finally, 68.5%, 25.4%, and 6.1% of patients had mild, moderate, and severe functional disability, respectively. The study found that the age of onset, clinical pattern, and disability from MS were consistent with studies in other Middle Eastern countries. However, the prevalence of MS in the study was relatively lower than in neighboring countries due to underestimation of the disease, limited tools for diagnosing MS, and a shortage of neurologists. The study emphasizes the importance of early diagnosis and proper management of MS to improve patients' quality of life.

Abstract
Introduction Several studies have investigated COVID-19 vaccine acceptability and hesitancy, especially among healthcare workers (HCWs). However, acceptability of the vaccine by HCWs in Sudan remains unclear. Aims We investigated acceptability of the COVID-19 vaccine and its determinants among HCWs in Sudan. Methods Using a semi-structured questionnaire, we conducted a web-based cross-sectional study of COVID-19 vaccine hesitancy and its associated determinants among healthcare workers in Sudan during March-April 2021. Results A total of 576 HCWs responded to the survey. Mean age was 35 years. Females (53.3%), medical doctors (55.4%) and being located in Khartoum State (76.0%) each accounted for more than half of the participants. Absolute refusal of the COVID-19 vaccine was expressed by 16.0% of the respondents. Males were more than twice as likely to accept the vaccine as females. Lower acceptability was statistically significantly associated with the nurses (OR = 0.35, 95% CI: 0.15-0.82, P < 0.001), increased perceived harm from the vaccine (OR = 0.11, 95% CI: 0.05-0.23, P < 0.001), lack of confidence in the source of the vaccine (OR = 0.16, 95% CI: 0.08-0.31, P < 0.001) and lack of confidence in organizations or government sectors supervising the vaccination process (OR = 0.31, 95% CI: 0.17-0.58, P < 0.001). Conclusion This study highlights a moderate level of COVID-19 vaccine acceptability among HCWs in Sudan. Special consideration should be given to addressing vaccine hesitancy among female HCWs and nurses.

Abstract
The receptor binding domain (RBD) of spike proteins plays a crucial role in the process of severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) attachment to the human angiotensin-converting enzyme 2 (ACE2). The N501Y mutation and later mutations introduced extra positive charges on the spike RBD and resulted in higher transmissibility, likely due to stronger binding with the highly negatively charged ACE2. Consequently, many studies have been devoted to understanding the molecular mechanism of spike protein binding with the ACE2 receptor. Most of the theoretical studies, however, have been done on isolated proteins. ACE2 is a transmembrane protein; thus, it is important to understand the interaction of spike proteins with ACE2 in a lipid matrix. In this study, the adsorption of ACE2 and spike (N501Y) RBD at a lipid/water interface was studied using the heterodyne-detected vibrational sum frequency generation (HD-VSFG) technique. The technique is a non-linear optical spectroscopy which measures vibrational spectra of molecules at an interface and provides information on their structure and orientation. It is found that ACE2 is effectively adsorbed at the positively charged 1,2-dipalmitoyl-3-trimethylammonium-propane (DPTAP) lipid monolayer via electrostatic interactions. The adsorption of ACE2 at the DPTAP monolayer causes a reorganization of interfacial water (D2O) from the D-down to the D-up orientation, indicating that the originally positively charged DPTAP interface becomes negatively charged due to ACE2 adsorption. The negatively charged interface (DPTAP/ACE2) allows further adsorption of positively charged spike RBD. HD-VSFG spectra in the amide I region show differences for spike (N501Y) RBD adsorbed at D2O, DPTAP, and DPTAP/ACE2 interfaces. A red shift observed for the spectra of spike RBD/DPTAP suggests that spike RBD oligomers are formed upon contact with DPTAP lipids.

Abstract
BACKGROUND Electronic prospective surveillance models (ePSMs) for cancer rehabilitation include routine monitoring of the development of treatment toxicities and impairments via electronic patient-reported outcomes. Implementing ePSMs to address the knowledge-to-practice gap between the high incidence of impairments and low uptake of rehabilitation services is a top priority in cancer care. METHODS We conducted a scoping review to understand the state of the evidence concerning the implementation of ePSMs in oncology. Seven electronic databases were searched from inception to February 2021. All articles were screened and extracted by two independent reviewers. Data regarding the implementation strategies, outcomes, and determinants were extracted. The Expert Recommendations for Implementing Change taxonomy and the implementation outcomes taxonomy guided the synthesis of the implementation strategies and outcomes, respectively. The Consolidated Framework for Implementation Research guided the synthesis of determinants based on five domains (intervention characteristics, individual characteristics, inner setting, outer setting, and process). RESULTS Of the 5122 records identified, 46 interventions met inclusion criteria. The common implementation strategies employed were "conduct educational meetings," "distribute educational materials," "change record systems," and "intervene with patients to enhance uptake and adherence." Feasibility and acceptability were the prominent outcomes used to assess implementation. The complexity, relative advantage, design quality, and packaging were major implementation determinants at the intervention level. Knowledge was key at the individual level. At the inner setting level, major determinants were the implementation climate and readiness for implementation. At the outer setting level, meeting the needs of patients was the primary determinant. Engaging various stakeholders was key at the process level. CONCLUSIONS This review provides a comprehensive summary of what is known concerning the implementation of ePSMs. The results can inform future implementation and evaluation of ePSMs, including planning for key determinants, selecting implementation strategies, and considering outcomes alongside local contextual factors to guide the implementation process.

Abstract
Background Ischemic mitral regurgitation (IMR) or functional MR intensity with or without repair increases the risk of coronary artery bypass grafting (CABG), and if the contaminant is undertaken, it doubles the risk of the surgery. This study aimed to characterize patients with concomitant CABG and mitral valve repair (MVR) and assess the surgical and long-term outcomes. Methods We conducted a cohort study from 2014 to 2020 on 364 patients who underwent CABG. A total of 364 patients were enrolled and divided into two groups. Group I (n= 349) included patients with isolated CABG, and Group II included patients who underwent CABG with concomitant mitral valve repair (MVR) (n= 15). Results Regarding preoperative presentation, most patients were male: 289 (79.40%), hypertensive 306 (84.07%), diabetic 281 (77.20%), dyslipidemic 246 (67.58%), presenting with NYHA classes III-IV: 200 (54.95%), and upon angiography, found to have the three-vessel disease: 265 (73%). Regarding their age mean± SD and Log EuroSCORE median (Q1-Q3), they had a mean age of 60.94± 10.60 years and a median score of 1.87 (1.13-3.19). The most prevalent postoperative complications were low cardiac output 75 (20.66%), acute kidney injury (AKI) 63 (17.45%), respiratory complications 55 (15.32%), and atrial fibrillation (AF) 55 (15.15%). Regarding long-term outcomes, most patients reported class I NYHA 271 (83.13%) and an echocardiographic decrease in MR severity. Patients with a CABG + MVR were significantly younger (53.93± 15.02 vs. 61.24± 10.29 years; P= 0.009), had a lower ejection fraction (33.6 [25-50] vs. 50 [43-55] %; p= 0.032), and had a higher prevalence of LV dilation (32 [9.17%]). EuroSCORE was significantly higher in patients with mitral repair (3.59 [1.54-8.63] vs. 1.78 (1.13-3.11); P= 0.022). The mortality percentage was higher with MVR but did not attain statistical significance. Intraoperative CPB and ischemic durations were longer in the CABG + MVR group. Furthermore, neurological complications were higher in patients with mitral repair (4 (28.57%) vs. 30 (8.65%), P= 0.012). The study's follow-up duration median was 24 (9-36) months. The composite endpoint occurred more frequently in older patients (HR: 1.05 [95% CI: 1.02-1.09]; 0.001), patients with low ejection fraction (HR: 0.96 [95% CI: 0.93-0.99]; P= 0.006) and in patients with preoperative myocardial infarction (MI) (HR: 2.3 [95%: 1.14- 4.68]; P= 0.021). Conclusion Most IMR patients benefited from CABG and CABG + MVR, as evident by NYHA class and echocardiographic follow-up. CABG + MVR had a higher Log EuroSCORE risk with increased intraoperative cardiopulmonary bypass (CPB) and ischemic durations, which may have played a role in increasing the incidence of postoperative neurological complications. On follow-up, no differences were reported between the two groups. However, age, ejection fraction, and a history of preoperative MI were identified as factors affecting the composite endpoint.

Abstract
A considerable epidemiological and pathogenetic overlap exists between tuberculosis (TB) and cardiovascular diseases (CVD). The objective of this study was to establish the prevalence of CVD in the TB population. A systematic literature search was performed using Scopus, PubMed, EBSCO, ProQuest, Web of Science on January 25, 2023 using the keywords: "Tuberculosis," "TB," "mycobacterium tuberculosis," and "cardiovascular disease," "CVD" and with individual terms of various CVDs. Observational Studies were included if they reported the prevalence of CVD in the presence of TB in an adult population. The Newcastle-Ottawa Scale was used for quality evaluation. Statistical analyses were performed using STATA version 17. From 10 studies involving 46715 TB patients, a combined prevalence of CVDs was found to be 11% (CI: 95%, 5-16) with significant heterogeneity across studies (I2 = 96.72%). This study showed a considerable prevalence of CVD among TB patients suggesting TB patients to consider cardiac examination.

Abstract
Patient satisfaction after inflatable penile prosthesis (IPP) has been linked to preexisting curvature; however the association with intraoperative asymmetric corporal measurements (ACM) has not been well described. We sought to identify incidence of ACM during IPP surgery, and relationship to penile curvature. A retrospective review of all patients undergoing primary IPP placement between 6/2019 and 6/2021 was performed. Logistic regression analysis was performed to identify factors associated with ACM and need for adjunct straightening techniques. A total of 273 patients underwent primary IPP. 27.8% had Peyronie's disease (PD) diagnosed preoperatively or detected intraoperatively. ACM was identified in 20.1% (55/273) patients. There was no significant difference in ACM in PD versus non-PD patients (p = 0.55). Most patients with ACM (78.2%, 43/55) underwent placement of asymmetric device. ACM did not predict need for invasive straightening maneuvers (p = 0.12). However ACM patients were significantly more likely to have mild residual curvature than those with symmetry (p < 0.0001). Our study is first to address management of idiopathic ACM and association with curvature, providing new insight into a common situation. While ACM was detected in 20%, it did not predict need for adjunct straightening techniques. Our findings may provide reassurance to urologists troubleshooting idiopathic ACM during corporal dilation during IPP surgery.

Abstract
AIMS Stereotactic body radiotherapy (SBRT) is increasingly used to treat sacral metastases. We analysed our centre's local relapse rates and patterns of failure after sacral SBRT and assessed whether using the consensus contouring recommendation (CCR) may have prevented local relapse. MATERIALS AND METHODS We conducted a single-centre retrospective review of patients treated with sacral SBRT between February 2012 and December 2021. The cumulative incidence of local relapse, patterns of failure and overall survival were determined. Two investigators reviewed planning computed tomography scans and imaging at relapse to determine if local relapse was potentially preventable with a larger CCR-derived radiotherapy field. RESULTS In total, 34 patients received sacral SBRT, with doses ranging from 24 to 40 Gy over three to five fractions. The most frequently used schedule was 30 Gy in three fractions. Common primaries treated included prostate (n = 16), breast (n = 6), lung (n = 3) and renal (n = 3) cancers. The median follow-up was 20 months (interquartile range 13-55 months). The cumulative incidence of local relapse (4/34) was 2.9% (95% confidence interval 0.2-13.2), 6.3% (95% confidence interval 1.1-18.5) and 16.8% (95% confidence interval 4.7-35.4) at 6 months, 1 year and 2 years, respectively. The patterns of failure were local-only (1/34), local and distant (3/34) and distant relapse (10/34). The overall survival was 96.7% (95% confidence interval 90.5-100) and 90.6% (95% confidence interval 78.6-100) at 1 and 2 years, respectively. For prostate/breast primaries, the cumulative incidence of local relapse was 4.5% (95% confidence interval 0.3-19.4), 4.5% (95% confidence interval 0.3-19.4) and 12.5% (95% confidence interval 1.7-34.8) at 6 months, 1 and 2 years, respectively. Twenty-nine cases (85.3%) deviated from the CCR. Sacral relapse was potentially preventable if the CCR was used in one patient (2.9% of the whole cohort and 25% of the relapsed cohort). DISCUSSION We have shown excellent local control rates with sacral SBRT, which was largely planned with a margin expansion approach.
