Abstract
PURPOSE/AIM Robotic-assisted techniques have the potential to revolutionize dental implantology by offering enhanced precision, accuracy, and clinical outcomes compared to computer-assisted implant placement techniques. This study aimed to evaluate the accuracy of dental implant placement using robot-assisted implant surgery in vitro settings. METHODS An unrestricted search of indexed databases along with a manual search was performed up to March 2024. In vitro, studies comparing the positioning accuracy of robotic systems in dental implant placement of planned pre-operative coordinates and postoperative outcomes in phantom and simulated models were included. QUIN Tool was used to assess the quality of the included studies. RESULT A total of 13 in vitro studies were included. All studies except one used entry, exit, or angle deviation as parameters to assess the accuracy of implants placed on phantom models or simulated virtual implant placement. Overall, pooled entry deviations were 0.72 ± 0.68 mm, exit deviations were 0.86 ± 0.92 mm, and angular deviations were 1.47 ± 1.610 favoring robot-assisted implant surgery. CONCLUSION Based on the current evidence, robotic-placed implants have the potential to revolutionize dental implantology by offering enhanced precision, accuracy, and clinical outcomes compared to dynamic and static computer-assisted implant surgery techniques.

Abstract
OBJECTIVE Amiodarone (AMD), a drug of choice to treat cardiac arrhythmias, has a narrow therapeutic index (NTI). It inhibits CYP3A4, CYP2C9, and CYP2D6 enzymes. Quercetin (QUE), a pharmacologically important bioflavonoid in vegetables and fruits, is important in treating cardiovascular comorbidities. QUE alters the bioavailability of drugs used concurrently by dual inhibition of P-glycoproteins (P-gp) and cytochrome (CYP) enzyme systems. The current study aimed to investigate the pre-treatment and co-administration effect of QUE on AMD pharmacokinetics in rats. MATERIALS AND METHODS Two separate animal trials (I and II) were planned to probe the effect of QUE on AMD pharmacokinetics by following previously cited studies. The pre-treatment group received oral doses of QUE for 14 days, and a single dose of AMD on the 15th day. Rats were administered single doses of QUE (20 mg/kg) and AMD (50 mg/kg) concurrently in a carboxymethylcellulose (CMC) in the co-administration study. Blood was collected at pre-determined time points. AMD was quantified by HPLC, and data was analyzed by PK solver software. RESULTS In the pre-treated group, peak plasma concentration (Cmax) and area under the curve (AUC0-∞) of AMD were increased by 45.52% and 13.70%, respectively, while time to achieve maximum concentration (tmax), half-life (t1/2) and clearance (CL) were declined by 35.72%, 16.75%, and 11.0% respectively compared to the control. In the co-administered group, compared to controls, Cmax and AUC0-∞ were elevated to 12.90% and 7.80%, respectively, while tmax, t1/2, and CL declined by 16.70%, 2.35%, and 13.40%. Further, AMD was increased in lung tissue of both treated groups, relative to the respective controls. CONCLUSIONS A notable pharmacokinetic drug interaction between QUE and AMD was observed in rats and warrants possible drug interaction study in humans, suggesting AMD dose adjustment specifically in patients with arrhythmia having a pre-treatment history and simultaneous administration of QUE-containing products.

Surgical management of colon cancer in ulcerative colitis patients with orthotopic liver transplant for primary sclerosing cholangitis. A systematic review. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2023; 49:106922. [PMID: 37210276 DOI: 10.1016/j.ejso.2023.04.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2022] [Revised: 03/13/2023] [Accepted: 04/27/2023] [Indexed: 05/22/2023]
Abstract
INTRODUCTION Colon cancer in ulcerative colitis patients with liver transplant (UCCOLT) due to primary sclerosing cholangitis carries significant treatment challenges. Aim of this literature search is to review management strategies and provide a framework to facilitate the decisional process in this clinical setting. METHODS PRISMA-compliant systematic search was followed by critical expert commentary of the results and development of a surgical management algorithm. Endpoints included surgical management, operative strategies, functional and survival outcomes. Technical and strategics aspects with particular regard to the choice of reconstruction were evaluated to tentatively develop an integrated algorithm. RESULTS Ten studies reporting treatment of 20 UCCOLT patients were identified after screening. Nine patients underwent proctocolectomy and end-ileostomy (PC) and eleven had restorative ileal pouch-anal anastomosis (IPAA). Reported results for perioperative outcomes, oncological outcomes, and graft loss were comparable for both procedures. There were no reports of subtotal colectomies and ileo-rectal anastomosis (IRA). CONCLUSIONS Literature in the field is scarce and decision-making is particularly complex. PC and IPAA have been reported with good results. Nevertheless, IRA may also be considered in UCCOLT patients in selected cases, reducing the risks of sepsis, OLT and pouch failure; furthermore, in young patients, it has the advantage of preserving fertility or sexual function. The proposed treatment algorithm may represent a valuable support in guiding surgical strategy.

Abstract
A novel ZnO-MoO3-ZnMoO3@graphene GZM composite catalyst prepared by microwave hydrothermal process for personal protective equipment textiles (PPE) is presented in this study. The results indicated that the GZM with defect vacancy sites of two types as observed by EPR showed significantly superior inactivation of the E. coli bacteria compared to GZM without the lower defect vacancy sites and concomitant lower electron densities. Photocatalytic activated oxidation by the GZM composites coatings was observed to proceed in acceptable times as well as the bacterial inactivation (log bact. C/Co > 107 within 3 h). Defect sites in the GZM seem to be important leading to the bacterial inactivation process. DFT calculations on the GZM with and without catalyst defect sites were carried out. The electron densities were estimated by the Fourier mapping. The results found in this study showed the potential of GZM-PPE for practical applications.

Self-perceived pain in Hyrax versus other maxillary expansion orthodontic appliances: a systematic review of clinical studies. Eur Arch Paediatr Dent 2023; 24:279-292. [PMID: 37022607 DOI: 10.1007/s40368-023-00795-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2022] [Accepted: 03/19/2023] [Indexed: 04/07/2023]
Abstract
PURPOSE To evaluate self-perceived pain levels in the Hyrax compared to other types of maxillary expansion (ME) appliances in growing patients. METHODS An unrestricted search of indexed databases and manual searching were performed up to October 2022. Randomized controlled trials (RCTs) comparing the Hyrax appliance with other ME appliances were included. Data screening, extraction, and Risk of Bias (RoB) assessment with the Cochrane tool were performed by two authors. RESULTS Six RCTs were included. The number of participants in the included RCTs ranged between 34 to 114 and included both male and female growing patients. Various tools were used to measure self-perceived pain including the Graphic Rating Scale for Pain, the Wong-Baker Faces Pain Scale, the Numerical Rating Scale, the visual analogue scale, and a questionnaire. One RCT reported that pain intensity in patients treated with the Hyrax was higher than in the Haas appliance, with a statistically significant difference limited to the first day. Two RCTs reported that pain intensity in patients treated with the Leaf expander was lower than in the Hyrax during the first 7 days of treatment. Two RCTs reported no significant differences in pain intensity between the Hyrax and other ME appliances. One RCT reported that pain intensity in patients using the computer-guided skeletal ME appliance was higher than in the Hyrax appliance at the first day after expansion. Four RCTs had a high RoB, and two RCTs had a moderate RoB. CONCLUSIONS Within the limitations of the present systematic review and based on the currently available evidence, it is challenging and inconclusive to identify the best maxillary expansion appliances, regarding pain levels for growing patients.

Abstract
Graphitic carbon nitride (g-C3 N4 ) has gained tremendous interest in the domain of power transformation and retention, because of its distinctive stacked composition, adjustable electronic structure, metal-free feature, superior thermodynamic durability, and simple availability. Furthermore, the restricted illumination and extensive recombination of photoexcitation radicals have inhibited the photocatalytic performance of pure g-C3 N4 . The dimensions of g-C3 N4 may impact the field of electronics confinement; as a consequence, g-C3 N4 with varying dimensions shows unique features, making it appropriate for a number of fascinating uses. Even if there are several evaluations emphasizing on the fabrication methods and deployments of g-C3 N4 , there is certainly an insufficiency of a full overview, that exhaustively depicts the synthesis and composition of diverse aspects of g-C3 N4 . Consequently, from the standpoint of numerical simulations and experimentation, several legitimate methodologies were employed to deliberately develop the photocatalyst and improve the optimal result, including elements loading, defects designing, morphological adjustment, and semiconductors interfacing. Herein, this evaluation initially discusses different dimensions, the physicochemical features, modifications and interfaces design development of g-C3 N4 . Priority is concentrated on the sensible layout, and advancement of g-C3 N4 for the diverse implementations in power transformation and inventory, such as photocatalytic H2 progression, photoreduction of CO2 source, electrocatalytic H2 development, O2 propagation, O2 reduction, alkali-metal battery cells, lithium-ion batteries, lithium-sulfur batteries, and metal-air batteries. Ultimately, the current challenges and potential of g-C3 N4 for fuel transformation and retention activities are explored.

Synergistic Functionality of Dopants and Defects in Co-Phthalocyanine/B-CN Z-Scheme Photocatalysts for Promoting Photocatalytic CO 2 Reduction Reactions. SMALL (WEINHEIM AN DER BERGSTRASSE, GERMANY) 2023:e2208179.

Abstract
The realization of solar-light-driven CO2 reduction reactions (CO2 RR) is essential for the commercial development of renewable energy modules and the reduction of global CO2 emissions. Combining experimental measurements and theoretical calculations, to introduce boron dopants and nitrogen defects in graphitic carbon nitride (g-C3 N4 ), sodium borohydride is simply calcined with the mixture of g-C3 N4 (CN), followed by the introduction of ultrathin Co phthalocyanine through phosphate groups. By strengthening H-bonding interactions, the resultant CoPc/P-BNDCN nanocomposite showed excellent photocatalytic CO2 reduction activity, releasing 197.76 and 130.32 µmol h-1 g-1 CO and CH4 , respectively, and conveying an unprecedented 10-26-time improvement under visible-light irradiation. The substantial tuning is performed towards the conduction and valance band locations by B-dopants and N-defects to modulate the band structure for significantly accelerated CO2 RR. Through the use of ultrathin metal phthalocyanine assemblies that have a lot of single-atom sites, this work demonstrates a sustainable approach for achieving effective photocatalytic CO2 activation. More importantly, the excellent photoactivity is attributed to the fast charge separation via Z-scheme transfer mechanism formed by the universally facile strategy of dimension-matched ultrathin (≈4 nm) metal phthalocyanine-assisted nanocomposites.

Abstract
The development of highly efficient and cost-effective hydrogen evolution reaction (HER) catalysts is highly desirable to efficiently promote the HER process, especially under alkaline condition. Herein, a polyoxometalates-organic-complex-induced carbonization method is developed to construct MoO2 /Mo3 P/Mo2 C triple-interface heterojunction encapsulated into nitrogen-doped carbon with urchin-like structure using ammonium phosphomolybdate and dopamine. Furthermore, the mass ratio of dopamine and ammonium phosphomolybdate is found critical for the successful formation of such triple-interface heterojunction. Theoretical calculation results demonstrate that such triple-interface heterojunctions possess thermodynamically favorable water dissociation Gibbs free energy (ΔGH2O ) of -1.28 eV and hydrogen adsorption Gibbs free energy (ΔGH* ) of -0.41 eV due to the synergistic effect of Mo2 C and Mo3 P as water dissociation site and H* adsorption/desorption sites during the HER process in comparison to the corresponding single components. Notably, the optimal heterostructures exhibit the highest HER activity with the low overpotential of 69 mV at the current density of 10 mA cm-2 and a small Tafel slope of 60.4 mV dec-1 as well as good long-term stability for 125 h. Such remarkable results have been theoretically and experimentally proven to be due to the synergistic effect between the unique heterostructures and the encapsulated nitrogen-doped carbon.

Abstract
The regulation of electron distribution of single-atomic metal sites by atomic clusters is an effective strategy to boost their intrinsic activity of oxygen reduction reaction (ORR). Herein we report the construction of single-atomic Mn sites decorated with atomic clusters by an innovative combination of post-adsorption and secondary pyrolysis. The X-ray absorption spectroscopy confirms the formation of Mn sites via Mn-N4 coordination bonding to FeMn atomic clusters (FeMnac /Mn-N4 C), which has been demonstrated theoretically to be conducive to the adsorption of molecular O2 and the break of O-O bond during the ORR process. Benefiting from the structural features above, the FeMnac /Mn-N4 C catalyst exhibits excellent ORR activity with half-wave potential of 0.79 V in 0.5 M H2 SO4 and 0.90 V in 0.1 M KOH as well as preeminent Zn-air battery performance. Such synthetic strategy may open up a route to construct highly active catalysts with tunable atomic structures for diverse applications.

Abstract
Inspired by natural photosynthesis, harnessing the wide range of natural solar energy and utilizing appropriate semiconductor-based catalysts to convert carbon dioxide into beneficial energy species, for example, CO, CH4 , HCOOH, and CH3 COH have been shown to be a sustainable and more environmentally friendly approach. Graphitic carbon nitride (g-C3 N4 ) has been regarded as a highly effective photocatalyst for the CO2 reduction reaction, owing to its cost-effectiveness, high thermal and chemical stability, visible light absorption capability, and low toxicity. However, weaker electrical conductivity, fast recombination rate, smaller visible light absorption window, and reduced surface area make this catalytic material unsuitable for commercial photocatalytic applications. Therefore, certain procedures, including elemental doping, structural modulation, functional group adjustment of g-C3 N4 , the addition of metal complex motif, and others, may be used to improve its photocatalytic activity towards effective CO2 reduction. This review has investigated the scientific community's perspectives on synthetic pathways and material optimization approaches used to increase the selectivity and efficiency of the g-C3 N4 -based hybrid structures, as well as their benefits and drawbacks on photocatalytic CO2 reduction. Finally, the review concludes a comparative discussion and presents a promising picture of the future scope of the improvements.

Abstract
BACKGROUND Oncoplastic breast surgery permits tumours traditionally requiring total mastectomy to be excised with acceptable oncological and aesthetic outcomes. The purpose of this study was to evaluate outcomes following oncoplastic breast surgery in the breast unit at Inkosi Albert Luthuli Central Hospital in Durban. METHODS This was a retrospective analysis of patient records. Patients who underwent oncoplastic breast surgery with curative intent from 2011 and 2012 were included in this study. Male patients, those with contraindications to breast conservation, and those with metastatic disease were excluded. Demographic and tumour-related data were collected and margin status, surgical site sepsis, recurrence and overall survival (OS) were recorded over a 5-year period starting from the date of presentation. RESULTS Forty-five patients with 45 tumours were evaluated. The most prevalent tumour size at presentation was T2 (55.6%), and the most commonly performed procedure was a therapeutic mammoplasty. Twelve patients (27%) developed surgical site infection (SSI), eight of which were classified as deep SSI with wound breakdown. The resection margin was clear in 95.6%. Recurrence was noted in 8.9% of patients, with an OS of 91.1%. CONCLUSION Breast-conserving surgery (BCS) using oncoplastic techniques results in favourable oncological outcomes in patients treated in a resource-constrained setting.

Synergetic effect of bismuth vanadate over copolymerized carbon nitride composites for highly efficient photocatalytic H 2 and O 2 generation. J Colloid Interface Sci 2022; 627:621-629.

Abstract
The development of copolymerized carbon nitride (CN)-based photocatalysts may support advances in photocatalytic overall water splitting. However, the recombination of charge carriers is the main bottleneck that reduces its overall photocatalytic activity. To overcome this problem, the construction of heterojunction technology has emerged as an effective approach to reduce the charge carrier recombination, thereby improving charge separation and transport efficiency. In this work, an innovative heterojunction was prepared between Quinolinic acid (QA) modified CN (CN-QAx) and novel nanorod-shaped bismuth vanadate (BiVO4) (BiVO4/CN-QAx) for overall water splitting through a simple in-situ solvent evaporation technique. The obtained results show that the synthesized samples have efficient and improved activities for releasing H2 (862.1 μmol/h) and O2 (31.58 μmol/h) under visible light irradiation. Furthermore, an exceptional apparent quantum yield (AQY) of 64.52 % has been recorded for BiVO4/CN-QA7.0 at 420 nm, which might be due to the substantial isolation of photoinducedcharge carriers. Therefore, this work opens up a new channel toward efficient CN-based photocatalysts in the sustainable energy production processes.

Evaluation of prognostic risk models for postoperative pulmonary complications in adult patients undergoing major abdominal surgery: a systematic review and international external validation cohort study. Lancet Digit Health 2022; 4:e520-e531.

Abstract
BACKGROUND Stratifying risk of postoperative pulmonary complications after major abdominal surgery allows clinicians to modify risk through targeted interventions and enhanced monitoring. In this study, we aimed to identify and validate prognostic models against a new consensus definition of postoperative pulmonary complications. METHODS We did a systematic review and international external validation cohort study. The systematic review was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched MEDLINE and Embase on March 1, 2020, for articles published in English that reported on risk prediction models for postoperative pulmonary complications following abdominal surgery. External validation of existing models was done within a prospective international cohort study of adult patients (≥18 years) undergoing major abdominal surgery. Data were collected between Jan 1, 2019, and April 30, 2019, in the UK, Ireland, and Australia. Discriminative ability and prognostic accuracy summary statistics were compared between models for the 30-day postoperative pulmonary complication rate as defined by the Standardised Endpoints in Perioperative Medicine Core Outcome Measures in Perioperative and Anaesthetic Care (StEP-COMPAC). Model performance was compared using the area under the receiver operating characteristic curve (AUROCC). FINDINGS In total, we identified 2903 records from our literature search; of which, 2514 (86·6%) unique records were screened, 121 (4·8%) of 2514 full texts were assessed for eligibility, and 29 unique prognostic models were identified. Nine (31·0%) of 29 models had score development reported only, 19 (65·5%) had undergone internal validation, and only four (13·8%) had been externally validated. Data to validate six eligible models were collected in the international external validation cohort study. Data from 11 591 patients were available, with an overall postoperative pulmonary complication rate of 7·8% (n=903). None of the six models showed good discrimination (defined as AUROCC ≥0·70) for identifying postoperative pulmonary complications, with the Assess Respiratory Risk in Surgical Patients in Catalonia score showing the best discrimination (AUROCC 0·700 [95% CI 0·683-0·717]). INTERPRETATION In the pre-COVID-19 pandemic data, variability in the risk of pulmonary complications (StEP-COMPAC definition) following major abdominal surgery was poorly described by existing prognostication tools. To improve surgical safety during the COVID-19 pandemic recovery and beyond, novel risk stratification tools are required. FUNDING British Journal of Surgery Society.

Abstract
Ultrafine particles (UFP), harmful to human health, are emitted at high levels from motorized traffic. Bicycle commuting is increasingly encouraged to reduce traffic emissions and increase physical activity, but higher breathing rates increase inhaled UFP concentrations while in traffic. We assessed exposure to UFP while cycling along a fixed 8.5 km inner-city route in Copenhagen, on weekdays over six weeks (from September to October 2020), during morning and afternoon rush-hour, as well as morning non-rush-hour, traffic time periods starting from 07:45, 15:45, and 09:45 h, respectively. Continuous measurements were made (each second) of particle number concentration (PNC) and location. PNC levels were summarized and compared across time periods. We used generalized additive models to adjust for meteorological factors, weekdays and trends. A total of 61 laps were completed, during 28 days (∼20 per time period). Overall mean PNC was 18,149 pt/cm3 (range 256-999,560 pt/cm3) with no significant difference between morning rush-hour (18003 pt/cm3), afternoon rush-hour (17560 pt/cm3) and late morning commute (17560 pt/cm3) [p = 0.85]. There was substantial spatial variation of UFP exposure along the route with highest PNC levels measured at traffic intersections (∼38,000-42000 pt/cm3), multiple lane roads (∼38,000-40000 pt/cm3) and construction sites (∼44,000-51000 pt/cm3), while lowest levels were measured at smaller streets, areas with open built environment (∼12,000 pt/cm3), as well as at a bus-only zone (∼15,000 pt/cm3). UFP exposure in inner-city Copenhagen did not differ substantially when bicycling in either rush-hour or non-rush-hour, or morning or afternoon, traffic time periods. UFP exposure varied substantially spatially, with highest concentrations around intersections, multiple lane roads, and construction sites. This suggests that exposure to UFP is not necessarily reduced by avoiding rush-hours, but by avoiding sources of pollution along the bicycling route.

Abstract
The COVID-19 is a contagious viral disease, was first emerged in Wuhan, China in December 2019 and became the whole world on alert. The mortality rate in top most countries in Asia with special reference to Pakistan has been focused. Since February 26 to September 2020 the total confirmed cases and mortality rate was measured through Wikipedia and the notable journals. Iran is the only country having highest number of deaths (5.73%) followed by Indonesia (3.77%) while Saudi Arabia shows the lowest number of deaths as 1.39%. In Pakistan the first case was confirmed in 26th February, 2020. The nCov-19 has closely related to severe acute respiratory syndrome (SARS) hence SARS COV-2 was named. This virus is responsible for more than 33.9 million deaths in over all the world as of 20th September, 2020. The number of new cases is increasing time to time. Sindh province of Pakistan has reported the highest number of cases till September, 20, 2020 as compared to other parts of the country and has the highest number of death followed by Khyber Pakhtunkhwa. Because of the person to person contact the disease is spreading rapidly. The individuals who has already infected with other diseases like cancer or diabetic etc. are vulnerable. The nCOV-19 is the most contagious due to its mode of transmission. There is still no vaccine is available for the treatment of disease caused by nCoV-2019. It is therefore the only option to control this pandemic is to adopt effective preventive measures.

Abstract
We describe a case report of a robotic total pelvic exenteration (TPE) performed for a locally advanced rectal cancer at our institution in August 2018. Technical details and comparison with published literature are discussed. A 62-year-old patient with a locally advanced low rectal cancer T4N1cM0 with extramural vascular invasion (EMVI) underwent an elective robotic pelvic clearance performed by the urology and colorectal teams. He received neoadjuvant long-course chemo-radiotherapy to downstage the rectal cancer. The primary tumour was T4N1c with involvement of the bladder (trigone area) and prostate. After neoadjuvant therapy, MRI scan showed tumour regression grade 4 (TRG4). The patient underwent single docking totally robotic pelvic clearance. Patient's body mass index (BMI) was 32. The operative time was 400 minutes with the docking time of 15 minutes. There were no intraoperative complications, and the blood loss was 100ml. Histology was ypT4b, ypN1b, ypMx with 2/9 positive lymph nodes, and there was a complete resection by >1mm at all margins. The postoperative complications were ileus and urinary tract infection. Length of stay was 11 days complicated by prolonged ileus requiring total parenteral nutrition (TPN). The 30-day follow-up had no postoperative complications or readmission. The robotic approach is safe and feasible for multiorgan resections for locally advanced pelvic cancers, with curative intent. The literature supports it by highlighting the advantages of robotic pelvic surgery: better access, stable platform, quick inter-specialty change of operator by use of dual console and superior visualisation.

Abstract
Abstract
Introduction/Objective
Myeloid sarcoma is a rare extramedullary manifestation of acute myeloid leukemia. There are very few studies regarding molecular findings in myeloid sarcoma or their associated myeloid leukemia
Methods/Case Report
We evaluated cases of myeloid sarcoma with concurrent or prior bone marrow studies diagnosed as acute myeloid leukemia, from 2014 to 2021. We searched our Anatomic pathology information system for the terms ‘myeloid sarcoma’ or ‘leukemia cutis’. Out of 58 cases of myeloid sarcoma, ten had next generation sequencing studies (FoundationOne Heme) performed on bone marrow aspirate. Results-There were 7 male and 3 female patients. Age range was from 1-79 yrs. Myeloid sarcoma involved the skin (n=7) or soft tissue (n=3). Most common mutated genes were KMT2A/MLL (n=4, all translocations/fusions) followed by AXL1 (n=3), TP53 (n=3), NRAS (n=2), TET2 (n=2) and CEPBA (n=2). KMT2A fusion partners were MLLT1/ENL (n=1), MLLT3 (n=1), and MLLT10/AF10 (n=2). In all except for one case that harbored KMT2A/MLL fusions, karyotype also showed translocation of KMT2A. Only one case had both an AXL stop codon and a KMT2A translocation, otherwise AXL1/CEBPA mutated cases and KMT2A/MLL mutated cases were mutually exclusive. Other mutated genes were PHF6, BRCA2, DNMT3A, NPM1, RAD21, CBL, KMD6A, and NF1; each found in one case.
Results (if a Case Study enter NA)
Our result support the notion of higher risk of myeloid sarcoma in KMT2A and TP53 mutated AMLs. Except for absence of spliceosomes mutation, the incidence of mutated genes and functional categories in our series is concordance with two previously published studies.
Conclusion
Our result support the notion of higher risk of myeloid sarcoma in KMT2A and TP53 mutated AMLs. Except for absence of spliceosomes mutation, the incidence of mutated genes and functional categories in our series is concordance with two previously published studies.

Abstract
Abstract
Introduction/Objective
Carcino-sarcoma of the pancreas is a rare tumor and very limited clinical and pathologic data have been reported in the literature. As per World Health Organization (WHO) classification of tumors of the digestive system, the carcinosarcoma of the pancreas is classified together with sarcomatoid carcinoma and anaplastic giant cell carcinomas in undifferentiated carcinoma of pancreas. Carcinosarcoma is a rare entity with very poor prognosis.
Methods/Case Report
Here we report a rare case of pancreatic carcinosarcoma in a 68 year old male patient who underwent a pancreatoduodenectomy for unilocular cystic mass in the head of the pancreas. The mass grossly replaces the whole head of the pancreas. Histologically, the lesion showed a high-grade spindle cell component and adjacent moderately differentiated adenocarcinoma. On immunohistochemical examination, the carcinomatous component was positive for epithelial markers, and the sarcomatous component was positive for DOG1 and had a focal cytoplasmic staining for S-100. The diagnosis of pancreatic carcinosarcoma was rendered. Treatment options are same as of pancreatic carcinoma. Surgical resection is the best option available for patients. Systemic chemotherapy is indicated for patients with distant metastasis or patients with other contraindications. Despite surgery and adjuvant chemotherapy, recurrence rates are high, and prognosis is poor. However, there are no relevant standard chemotherapies available. Based on the limited number of reported cases, the prognosis of carcinosarcoma of the pancreas appears to be poor. But some cases with long term survival have been reported. There are very few primary pancreatic neoplasms with carcinomatous and sarcomatous components reported in the current literature.
Results (if a Case Study enter NA)
NA
Conclusion
This case highlights the importance of familiarity with histopathology of this rare entity, and to order proper immunohistochemical and molecular work-up when there is a suspicious abnormal spindle cell component.

Abstract
Introduction Personal protective equipments (PPEs) are like war uniforms in the fight against Corona Pandemic. The limited supply of PPEs warrant their proper use not only to avoid shortage of supplies but also to prevent any infectious spread to healthcare workers. This study aimed at analyzing awareness among non-consultant hospital doctors re proper use of PPEs Method A questionnaire was devised using local available guidelines published by university Hospital Limerick. The study was done in 2 phases. In 1st phase 100 questionnaires were distributed to non-consultant hospital doctors(NCHDs). Results were analysed and after 1st phase and emails were sent with results and local guidelines and a zoom educational session was organized. In 2nd phase, questionnaire was redistributed in a week's time and results were re analysed to close the loop. Results 200 NCHDs participated in the study,100 in each phase. Most common age group in two phases was 21-30 yrs. Awareness about PPEs use for Covid 19 increased significantly in 2nd phase across all domains (what is included in PPEs (100% from 91%), Sequence for putting on PPEs (52% to 88% p < 0.05), steps for FIT test (57% to 74% p = 0.247) and sequence for removing PPEs (47% to 81% p < 0.05). Conclusions Though PPEs donning and doffing sessions were organized by the hospital officially, Awareness about effective use of PPEs among NCHDs further improved after organizing a Zoom educational session and auditing.

Abstract
Diabetes mellitus (DM) is a non-communicable disease throughout the world in which there is persistently high blood glucose level from the normal range. The diabetes and insulin resistance are mainly responsible for the morbidities and mortalities of humans in the world. This disease is mainly regulated by various enzymes and hormones among which Glycogen synthase kinase-3 (GSK-3) is a principle enzyme and insulin is the key hormone regulating it. The GSK-3, that is the key enzyme is normally showing its actions by various mechanisms that include its phosphorylation, formation of protein complexes, and other cellular distribution and thus it control and directly affects cellular morphology, its growth, mobility and apoptosis of the cell. Disturbances in the action of GSK-3 enzyme may leads to various disease conditions that include insulin resistance leading to diabetes, neurological disease like Alzheimer's disease and cancer. Fluoroquinolones are the most common class of drugs that shows dysglycemic effects via interacting with GSK-3 enzyme. Therefore, it is the need of the day to properly understand functions and mechanisms of GSK-3, especially its role in glucose homeostasis via effects on glycogen synthase.

Abstract
Asiatic black bear is present in variety of habitats like broad-leaves and coniferous forests, extending form sea level to 4300m elevation and change their habitat for food purpose seasonally. The present study was conducted at Kaghan and Siran Valleys, District Mansehra, Khyber Pakhtunkhwa, Pakistan to assess habitat of black bear. Line transect method was used for observation of bear signs. Twelve meter circular radius plots were selected for the concern vegetation's i.e. (trees, shrubs and herbs) and three to six plots were placed in each transect. At the result of sign survey, thirteen different categories of bear signs were recorded and encounter rate was calculated for each sign. A total of 1858 signs were observed during field surveys. Total (81%) coniferous species were recoded among trees, with the highest appearance of Pinus wallichiana (34.22%) and Spruce spp (27.76%), similarly broad leaves trees (18.56%) were also recoded from habitat plots. Most of the signs were encountered in bushy areas, whereas high number of Viburnum Spp (60.29%) was present. It is indicated that black bear prefers blend of Coniferous Trees, Viburnum and Ferns Species; probably because these plants provide enough food, protection, and meticulous shelter because more than 80% of habitat composed of these three species. Currently habitat destruction and increase in human population are the up-growing issues for wild animals (especially Asiatic black bear), which is highly sensitive to such problems. High levels of conservation efforts are recommended for the protection of black bear habitat and to avoid human interference in their territory.

Abstract
Stunting is a significant public health problem in low- and middle-income countries. This study assessed the prevalence of stunting and associated risk factors of stunting among preschool and school-going children in flood-affected areas of Pakistan. A cross-sectional study was conducted by visiting 656 households through multi-stage sampling. Respondent's anthropometric measurements, socio-demographic information and sanitation facilities were explored. A logistic regression model was used to determine determinants of stunting, controlling for all possible confounders. The overall prevalence of stunting in children was 40.5%, among children 36.1% boys and 46.3% of girls were stunted. The prevalence of stunting in under-five children was 50.7%. Female children (OR=1.35, 95% CI:0.94-2.0), children aged 13-24 months (OR=6.5, 95% CI: 3.0-13.9), mothers aged 15-24 years (OR=4.4, 95% CI: 2.6-7.2), joint family (OR=2.1, 95% CI: 1.4-3.0) did not have access to improved drinking water (OR=3.3, 95% CI: 1.9-5.9), and the toilet facility (OR=2.8, 95% CI, 1.9-4.3), while the children from district Nowshera (OR=1.7, 95% CI: 0.9-3.2) were significantly (P<0.05) associated in univariate analysis. The regression model revealed that child age, maternal age, family type, quality of water, and toilet facility, were the significant (P<0.05) factors contributing to child stunting in the flood-hit areas. Identification of key factors might be helpful for policymakers in designing comprehensive community-based programs for the reduction of stunting in flood-affected areas. In disasters such as flood, the detrimental consequences of the stunting problem could be even more on children. Evidence-based education and care must be provided to the families in the flood-affected regions to reduce the stunting problem. The determinants of stunting should be targeted by making comprehensive policies regarding proper nutrition, livelihood, clean water, and sanitation facilities in flood-hit regions.

Abstract
There is a controversy in regards to the efficacy of photobiomodulation (PBM) in the management of tinnitus. The aim was to systematically review randomized controlled trials (RCTs) that assessed the efficacy of PBM (low-level laser therapy) in the management of tinnitus. The focused question was "Is PBM effective in the management of tinnitus?". Indexed databases were searched up to and including June 2020 using different combinations of the following key words: (a) laser; (b) diode; (c) low-level laser therapy; (d) photobiomodulation; (e) tinnitus; (f) medium-level laser; (g) photo-biomodulation; and (h) low-power laser; and RCTs performed on humans were included. Letters to the editor; case reports/series; commentaries; experimental studies and historic reviews were excluded. The risk of bias was assessed using the modified cochrane collaboration tool. The format of the current systematic review was personalized to summarize the appropriate information. Ten RCTs (2 single-blinded and 8 double-blinded) were included. One study reported 30% and 100% resolution of tinnitus using diode and Neodymium-doped Yttrium Aluminum Garnet lasers; respectively. One study reported that PBM was effective in relieving tinnitus for up to 3 months. Eight studies reported that PBM was ineffective in the management of chronic tinnitus. The risk of bias was high; medium and low in 4; 5 and 1 studies; respectively. The effectiveness of PBM in the management of tinnitus remains debatable. Further power-adjusted and well-designed RCTs with long-term follow-up are needed.

Introduction
Interatrial septal aneurysm (IASA) appears as a localised saccular deformity usually detected during routine echocardiography or stroke evaluation. Imaging hallmarks are >15mm prolapsing motion across the interatrial septum (IAS) and identical content to blood-pool, which are in contrast to this patient.
Clinical case
An 81-year-old asymptomatic man underwent transesophageal echocardiographic (TEE) right atrial mass assessment revealing a well-circumscribed, mobile mass attached to the interatrial septum suggestive of myxoma. Given previously-excised renal cell carcinoma, gadolinium contrast-enhanced cardiovascular magnetic resonance (CMR) imaging was performed for mass characterisation. Mass signal intensity (SI) was distinct to blood-pool, in keeping with mass content not being blood. Cine imaging revealed an isointense, mobile mass (Figure 1, Video 1) attached to the fossa ovalis. The mass was of intermediate SI isointense to myocardium on T1-weighted, and bright and hyperintense on T2-weighted imaging. First-pass perfusion (Video 2) and early enhancement imaging demonstrated a hypointense, non-perfusing mass. The mass hyperenhanced on late enhancement imaging excluding the differential of thrombus. Imaging findings were entirely consistent with atrial myxoma. Intraoperatively, the excised mass was actually confirmed as an IASA with exquisitely tight neck.
Discussion
This is the first case of IASA mimicking atrial myxoma on CMR imaging. We postulate that it behaved like a non-perfusing mass as its uniquely narrow neck resulted in extremely slow flow in and out. This permitted minimal blood with contrast entry which remained ‘trapped’ within, resulting in distinct SI to blood pool, and late hyperenhancement. Left atrial pressures forced the mass into the right atrium, preventing typical lateral IASA motion.
Conclusion
The diagnosis of IASA is best established with TEE while CMR imaging is the reference standard imaging modality for tissue characterization. It is vital to be able to identify and differentiate such entities to avoid misdiagnosis of an IASA as a cardiac myxoma or a malignant cardiac tumour. Nevertheless, we recognize the presence of limitation of imaging in this extraordinary case.

Abstract
There are growing numbers of adults with Duchenne Muscular Dystrophy living well into their fourth decade. These patients have complex medical needs that to date have not been addressed in the International standards of care. We sought to create a consensus based standard of care through a series of multi-disciplinary workshops with specialists from a wide range of clinical areas: Neurology, Cardiology, Respiratory Medicine, Gastroenterology, Endocrinology, Palliative Care Medicine, Rehabilitation, Renal, Anaesthetics and Clinical Psychology. Detailed reports of evidence reviewed and the consensus building process were produced following each workshop and condensed into this final document which was approved by all members of the Adult North Star Network including service users. The aim of this document is to provide a framework to improve clinical services and multi-disciplinary care for adults living with Duchenne Muscular Dystrophy.

Abstract
The preservation of cultural heritage materials requires extremely low concentration limits for indoor pollutants. This poses an unmet challenge for monitoring the artwork in museums and on exhibit, especially to do so in a cost-effective manner for a large number of locations. A novel type of colorimetric sensor array based on printed inks of 10 nm silver nanoparticles (AgNPs) with several different capping agents has been developed as an alternative to metal coupons or other passive sampling indicators traditionally used by conservators. The AgNP colorimetric sensor array, combined with digital imaging, offers ultrasensitive dosimetric identification of acidic and oxidizing gases and other air pollutants commonly found in a museum; the limits of detection are sub-ppb for 1 h exposures. For an array of AgNP inks with various capping agents, a unique and distinguishable color response pattern is observed for each specific analyte. Excellent discrimination among 11 gas pollutants over a wide range of concentrations was demonstrated using standard chemometric methods. The observed changes in color during pollutant exposure originate from the sintering of solid-state nanoparticles that leads to changes in the localized surface plasmon resonance. Such chemically induced sintering mechanism of nanoparticles paves the way for a new class of field-deployable solid-state optical sensor arrays. As an example, we have demonstrated the use of AgNP sensor arrays for the nondestructive analysis of acidic volatile emission from five types of printing paper, relevant for the conservation of cultural heritage objects, including ancient manuscripts and books.

Abstract
Plastic pollution in the oceans is a priority environmental issue. The recent increase in research on the topic, coupled with growing public awareness, has catalyzed policymakers around the world to identify and implement solutions that minimize the harm caused by plastic pollution. To aid and coordinate these efforts, we surveyed experts with scientific experience identified through their peer-reviewed publications. We asked experts about the most pressing research questions relating to how biota interact with plastic pollution that in turn can inform policy decisions and research agendas to best contribute to understanding and reducing the harm of plastic pollution to biota. We used a modified Horizon Scan method that first used a subgroup of experts to generate 46 research questions on aquatic biota and plastics, and then conducted an online survey of researchers globally to prioritize questions in terms of their importance to inform policy development. One hundred and fifteen experts from 29 countries ranked research questions in six themes. The questions were ranked by urgency, indicating which research should be addressed immediately, which can be addressed later, and which are of limited relevance to inform action on plastics as an environmental pollutant. We found that questions relating to the following four themes were the most commonly top-ranked research priorities: (i) sources, circulation and distribution of plastics, (ii) type of harm from plastics, (iii) detection of ingested plastics and the associated problems, and (iv) related economies and policy to ingested plastics. While there are many research questions on the topic of impacts of plastic pollution on biota that could be funded and investigated, our results focus collective priorities in terms of research that experts believe will inform effective policy and on-the-ground conservation.

Abstract
BACKGROUND AND AIMS Patients who develop infections of the pleura have several risk factors for malignancies, particularly lung cancer, and the infections might even be caused by undiagnosed intra-thoracic neoplasms. The aim of the study was to compare the occurrence of lung cancer and other malignancies between patients treated for pleural infections and controls during long-term follow-up. MATERIALS AND METHODS All consecutive patients treated for pleural infections between January 2000 and June 2016 at the Tampere University Hospital were included. Ten matched controls and data regarding later cancer diagnoses were requested from national registries. The cancer types and rates, the diagnostic delays, as well as survival were compared between patients and controls. RESULTS The material comprised 506 patients and 5022 controls (78% was male and median age was 60 years in both groups) with a median follow-up time of 69 months. In total, 74% of pleural infections were related to pneumonia. The occurrence of lung cancer during follow-up was 3.0% in all patients, 2.2% in pneumonia-related cases, and 0.6% in controls, p < 0.001 when compared with controls. The overall rate of non-pulmonary malignancies did not differ. Lung cancer was diagnosed within 3 months in 73% of patients versus in 6.9% of controls, p < 0.001. The survival in patients with later lung cancers or other malignancies was inferior to that of controls with similar neoplasms. CONCLUSION The rate of lung cancer diagnoses was significantly increased in patients treated for pleural infections when compared with matched controls and the prognosis of patients with subsequent malignancies was impacted.

Abstract
Photocatalytic full water splitting remains the perfect way to generate oxygen (O2) and hydrogen (H2) gases driven by sunlight to address the future environmental issues as well as energy demands. Owing to its exceptional properties, polymeric carbon nitride (PCN) has been one of the most widely investigated semiconductor photocatalysts. Nevertheless, blank PCN characteristically displays restrained photocatalytic performance due to high-density defects in its framework that may perhaps perform the part of the recombination midpoint for photoproduced electron-hole pairs. Therefore, to overcome this problem, a simple approach to introduce 7,7,8,8-tetracyanoquinodimethane (TCNQ) with an electron-withdrawing characteristic modifier into the pristine PCN framework by the ionothermal method to enhance its optical, conductive, and photocatalytic properties has been undertaken. Results show that such integration of TCNQ results in the delocalization of the π-conjugated structure; significant changes in its chemical electronic configuration, band gap, and surface area; and enhanced production of electrons under visible light. As a result of this facile integration, our best sample (CNU-TCNQ9.0) produced a hydrogen evolution rate (HER) of 164.6 μmol h-1 for H2 and an oxygen evolution rate (OER) of 14.8 μmol h-1 for O2, which were found to be 2.4- and 2.6-fold greater than those produced with pure carbon nitride (CNU) sample, respectively. Hence, this work provides a reasonable alternative method to synthesize and design novel CNU-TCNQ backbone photocatalyst for organic photosynthesis, CO2 reduction, hydrogen evolution, etc.

Abstract
BACKGROUND Repeated intestinal resections may have disabling consequences in patients with Crohn's disease even in the absence of short bowel syndrome. Our aim was to evaluate the length of resected small bowel in patients undergoing elective and emergency surgery for ileocolic Crohn's disease. METHODS A prospective observational study was conducted on patients undergoing surgery for ileocolonic Crohn's disease in a single colorectal centre from May 2010 to April 2018. The following patients were included: (1) patients with first presentation of ileocaecal Crohn's disease undergoing elective surgery; (2) patients with ileocaecal Crohn's disease undergoing emergency surgery; (3) patients with recurrent Crohn's disease of the distal ileum undergoing elective surgery. The primary outcomes were length of resected small bowel and the ileostomy rate. Operating time, complications and readmissions within 30 days were the secondary outcomes. RESULTS One hundred and sixty-eight patients were included: 87 patients in the elective primary surgery group, 50 patients in the emergency surgery group and 31 in the elective redo surgery group. Eleven patients (22%) in the emergency surgery group had an ileostomy compared to 10 (11.5%) in the elective surgery group (p < 0.0001). In the emergency surgery group the median length of the resected small bowel was 10 cm longer than into the group having elective surgery for primary Crohn's disease. CONCLUSIONS Patients undergoing emergency surgery for Crohn's disease have a higher rate of stoma formation and 30-day complications. Laparoscopic surgery in the emergency setting has a higher conversion rate and involves resection of longer segments of small bowel.

Abstract
We present a method for realizing a solid-state volumetric display based on the chromatic dispersion properties of a 150 mm diffractive lens that images a series of planar patterns presented by a digital micro-mirror device projector. The projector is driven by a narrowband polychromatic source, where the position of each image plane is defined by a distinct wavelength of light. The volumetric display system achieves 20 image planes at a volume refresh rate of 20 Hz, creating a volume of 17.4 cm3 with 13 mm of depth and a field of view of 10° floating 145 mm above the lens in real space.
