Abstract
BACKGROUND Data are lacking on patient-reported outcomes (PRO) following cryoballoon ablation (CBA) versus radiofrequency ablation (RFA). We sought to evaluate QoL and clinical outcomes of cryoballoon pulmonary vein isolation only (CRYO-PVI-ONLY) versus RFA with PVI and posterior wall isolation (RF-PVI+PWI) in a large prospective PRO registry. METHODS Patients who underwent AF ablation (2013-2016) at our institution were enrolled in an automated, prospectively maintained PRO registry. CRYO-PVI-ONLY patients were matched (1:1) with RF-PVI+PWI patients based on age, gender, and type of AF (paroxysmal vs. persistent). QoL and clinical outcomes were assessed using PRO surveys at baseline and at 1-year. The atrial fibrillation symptom severity scale (AFSSS) was the measure for QoL. Additionally, we assessed patient-reported clinical improvement, arrhythmia recurrence, and AF burden (as indicated by AF frequency and duration scores). RESULTS A total of 296 patients were included (148 in each group, 72% paroxysmal). By PRO, a significant improvement in QoL was observed in the overall study population and was comparable between CRYO-PVI-ONLY and RF-PVI+PWI (baseline median AFSSS of 11.5 and 11; reduced to 2 and 4 at 1 year, respectively; p = 0.44). Similarly, the proportion of patients who reported improvement in their overall QoL and AF related symptoms was high and similar between the study groups [92% (CRYO-PVI-ONLY) vs. 92.8% (RF-PVI+PWI); p = 0.88]. Arrhythmia recurrence was significantly more common in the CRYO-PVI-ONLY group (39.7%) compared to RF-PVI+PWI (27.7 %); p = 0.03. Comparable results were observed in paroxysmal and persistent AF. CONCLUSION CRYO-PVI-ONLY and RF-PVI+PWI resulted in comparable improvements in patient reported outcomes including QoL and AF burden; with RF-PVI+PWI being more effective at reducing recurrences.

Abstract
Himalayan 'Ecotone' temperate conifer forest is the cradle of life for human survival and wildlife existence. In spite of the importance of these areas, they have not been studied in depth. This study aimed to quantify the floristic structure, important value index (IVI), topographic and edaphic variables between 2019 and 2020 utilizing circular quadrant method (10 m x 10 m). The upper-storey layer consisted of 17 tree species belongs to 12 families and 9 orders. Middle-storey shrubs comprised of 23 species representing 14 families and 12 orders. A total of 43 species of herbs, grasses, and ferns were identified from the ground-storey layer, representing 25 families and 21 orders. Upper-storey vegetation structure was dominated by Pinus roxburghii (22.45 %) and middle-storey by Dodonaea viscosa (7.69 %). However, the ground layer vegetation was diverse in species composition (43 species) and distribution. The floral vegetation structure was encompassing of three floral communities which were diverse in IVI, such as, in Piro-Aial (Group 2), Pinus roxburghii (54.46 x 15.94) had the highest IVI value, followed by Pinus wallichiana (45.21 x 14.85) in Piwa-Quin (Group 3) and Ailanthus altissima (22.84 x 19.25) in Aial-Qugal (Group 1). However, the IVI values for Aesculus indica, Celtis australis, and Quercus incana in Aial-Qugal (Group 1) were not determined due to low detection rate. Nevertheless, eleven of these species showed 0 IVI values in Piro-Aial (Group 2) and Piwa-Quin (Group 3). CCA ordination biplot illustrated the significant differences among floral communities and its distribution, which impacted by temperature, rainfall, soil pH, altitude, and topographic features. Ward's agglomerative clustering finding reflected 'Ecotone' temperate conifer forest is rich and diverse floristic structure.

Abstract
Abstract Payment for ecosystem services (PES) is a mechanism where a consumer is able and ready to pay for the protection of the precise ecosystem service and there must be a provider such as local societies receiving an economic resource, who in return, must have the ability to maintain that ecosystem service. Economic valuation provides basis for payment for ecosystem services. Therefore, objective of this study was to evaluate tourism and carbon stock services of the Islamabad Capital Territory (ICT), Pakistan. Two forest zones (Chirpine and Scrub) of Islamabad capital territory (ICT) were selected for estimation of carbon stock and their carbon credits and carbon worth, a questionnaire-based survey was conducted for tourism as a payment for ecosystem services. The method for carbon stock assessment was systematic sampling for Chirpine forest whereas random sampling was done for scrub forest. The size of sampling plot was 17.84 m radius, and a total of 93 plots (49 Scrub zone and 44 Chirpine zone) was taken in the study area. The carbon stock of both zones (Chirpine and Scrub zone) is 22556.75 ton/ha (Chirpine 20105.79, Scrub 2450.96) and total carbon dioxide sequestered by both zone is 82557.72 ton/ha (Chirpine 73587.2, Scrub 8970.52), total carbon credits of both zone is 302160.87 (Chirpine 269328.97, Scrub 32831.9) and the carbon worth of both Chirpine and scrub zone is 4532418.92 $ (Chirpine 4039937.09$, Scrub 492481.83$). Similarly, from tourism point of view, in Shakar Parian, 94% tourists were agreed for PES whereas 6% were disagreed for the PES (the 6% tourist were disagreed to contribute for PES, 40% were agreed for Rs.5 contribution and 54% for Rs.10.). moreover, in Lake view Park, 97% tourists were agreed and 3% are disagreed (In Lake View Park 5% tourists were disagreed for the PES contribution whereas 32% were agreed for Rs.5 and 63% were for Rs.10). In Damen e Koh, around 87% tourist were agreed and 13% were disagreed, (24% were agreed for the contribution of Rs.5 and 63% tourists were agreed for the contribution of Rs.10). In Marghazar Zoo, 93% tourists were agreed (22% were agreed for contribution of Rs.5 and 71% tourist were agreed for contribution of Rs.10) and 7% are disagreed for PES whereas 7% tourists were not agreed for contribution. PES may implement to compensate forest and parks manager to ensure better management of the forests and parks. Due to prime location and scenic beauty of the ICT, it has huge potential for implementation of PES mechanism for sustainable forest management and conservation. Therefore, it is recommended that Capital Development Authority (CDA) Islamabad should devise a plan for implementation of PES in forests and parks of ICT for its sustainable management of recreational and forest resources.

Abstract
PURPOSE/OBJECTIVE(S) CNS lymphoma (CNSL) is an aggressive liquid cancer with the potential for rapid progression. Standard treatment regimens for CNSL have included chemotherapy and whole brain radiotherapy (WBRT). WBRT carries a high risk of leukoencephalopathy (LE) manifesting as cognitive decline and is identifiable on brain MRI as fluid attenuation inversion recovery (FLAIR) changes. Stereotactic radiosurgery (SRS) can precisely deliver higher biologically effective doses of radiation, while minimizing damage to surrounding healthy brain tissue. SRS offers enhanced local control in CNSL with minimal risk of LE. MATERIALS/METHODS Patients undergoing SRS at an NCI-designated comprehensive cancer center from 2000 to 2022 were prospectively enrolled into a database. Twenty-nine consecutive patients diagnosed with relapsed primary CNSL (59%) or secondary CNSL (41%) were included in this study. Median age at diagnosis was 70 (range 23-91) years and 14 were female. Follow up MRI imaging was obtained at 1-, 3-, 6- and 12-months post-procedure. Measurement of tumor volumes was performed at treatment and each subsequent follow-up by image co-registration and tumor segmentation. Pre and post SRS brain MRIs were independently reviewed by a neuro-radiologist to score the grade of LE for each patient. Progression-free survival (PFS) and overall survival (OS) were calculated using Kaplan-Meier analyses and Log-rank tests using statistical software. RESULTS Twenty-nine patients treated for 50 tumors were studied. Twenty-four patients were treated for a single tumor, and 5 for multiple tumors. Six patients underwent repeat SRS treatment for 10 out-of-field recurrences and 1 patient for an in-field recurrence. Of the 35 SRS procedures performed, 32 (88%) were single session delivery and 3 were hypofractionated. Stereotactic immobilization was achieved with frame (57%) or thermoplastic mask (43%). Median prescribed dose was 14 Gy (range 10-21) to the 50% isodose line (range 40-100). Median coverage, selectivity and gradient index were 0.97, 0.69, and 2.9 respectively. Median follow-up time was 4.5 months (range 0.5-64). Twenty-six (52%) tumors completely responded to treatment with no residual enhancement, while the rest decreased in volume. No tumor failed to respond to treatment. Median time to best volumetric response was achieved in 2.9 months (range 1-6.1) and median volume of best response was zero cc (range 0-1.19). The median OS of the cohort was 7.0 months (95% CI 5.1-8.9), while the median PFS was 5.0 months (95% CI 1.2-8.8). Median score of LE was zero, and only one patient experienced grade 3 MRI FLAIR changes. CONCLUSION With a median time to response of 2.9 months, a 100% initial response rate and a single in-field failure, our analysis demonstrates a rapid and effective response of CNSL to SRS. Distant failures were controlled with repeat SRS. The absence of LE in the treated patients provides further evidence for safety and tolerability of SRS in CNSL.

Abstract
PURPOSE/OBJECTIVE(S) NRG/RTOG 0126, a phase III trial for men with localized prostate cancer testing whether dose escalation to 79.2 Gy with 3DCRT/IMRT improved overall survival (OS). Long-term results of this trial are presented. MATERIALS/METHODS Patients with clinical stage T1b-T2b and either Gleason Score (GS) 2-6 and 10 ≤ PSA < 20 or GS 7 and PSA < 15 were eligible and randomized to receive 79.2 Gy or 70.2 Gy. No previous or concurrent androgen withdrawal therapy was administered. Treatment was delivered with 3DCRT/IMRT to a dose of 79.2 Gy in 44 fractions or 70.2 Gy in 39 fractions to the PTV encompassing the prostate and seminal vesicles. Image guidance was not required. ASTRO and Phoenix definitions were used for biochemical failure (ABF and PBF, respectively). OS was estimated by the Kaplan-Meier method and arms compared with the log-rank test. ABF, PBF, local progression (LP), distant metastases (DM) and time to late GI/GU toxicities were estimated by the cumulative incidence method and arms compared with Gray's test. RESULTS One thousand five hundred thirty-two men were randomized, 763 to 79.2 Gy and 769 to 70.2 Gy. 1499 were eligible, 748 and 751 in the 79.2 Gy and 70.2 Gy arms respectively. Median age was 71, 70% had PSA < 10 ng/ml, 84% with GS 7, 57% had T1 disease, and 66% treated with 3D-CRT. Outcomes are shown in the TABLE: . With a median follow up of 12 years, there was no significant difference in OS. There was a statistically significant decrease in the cumulative incidence of ABF, PBF, DM, LP, and salvage therapies in the 79.2 Gy arm. There were significantly higher rates of grade 2+ GI and GU toxicity in the 79.2 Gy arm. There were no statistically significant differences in the rates of grade 3+ GU or GI toxicity between either arm. CONCLUSION Long term follow up confirms no improvement in OS with dose escalation in this study population. However, there are significant improvements in ABF, PBF, DM, LP, and need for salvage therapy. Despite the use of more salvage therapy in the low dose arm, dose escalated RT resulted in lower rates of DM, a clinically relevant endpoint. Patients receiving dose escalation do experience a higher rate of grade 2+ GU and GI toxicity but no worse grade 3+ toxicities.

Abstract
PURPOSE/OBJECTIVE(S) To assess whether the efficacy of a hypofractionated (H) schedule is no worse than a conventional (C) schedule in men with low-risk prostate cancer. MATERIALS/METHODS Accrual began April 2006 and ended in December 2009. 1115 men with favorable-risk prostate cancer were randomly assigned 1:1 to a conventional (C) schedule (73.8 Gy in 41 fractions over 8.2 weeks) or to a hypofractionated (H) schedule (70 Gy in 28 fractions over 5.6 weeks). The trial was designed to establish with 90% power and alpha = 0.05 that (H) results in 5-year disease-free survival (DFS) that is not lower than (C) by more than 7% (hazard ratio (HR) < 1.52). Protocol specified secondary endpoints evaluated for noninferiority include: biochemical recurrence (BR), local progression, disease-specific survival, and overall survival. RESULTS One thousand ninety-two protocol eligible men were analyzed: 542 to C and 550 to H. Median follow-up is 12.75 years. Baseline characteristics were not different according to treatment arm. The estimated 12-year DFS is 56.1% (95% CI 51.5, 60.5) in the C arm and 61.8% (57.2, 66.0) in the H arm. The DFS hazard ratio (H/C) is 0.85 (0.71-1.03), confirming non-inferiority (p<0.001). Twelve-year cumulative incidence of biochemical recurrence (BR) was 17.0% (CI 13.8, 20.5) in the C-RT and 9.9% (CI 7.5, 12.6) in the H-RT arm; (HR = 0.56, (0.40-0.78) suggesting improved efficacy with H. Additional pre-specified secondary endpoints were non-inferior Late Grade ≥ 3 GI toxicity is 3.2% (C) vs. 4.4% (H), Relative risk (RR) for H vs. C 1.39 (CI 0.75, 2.55) Late Grade ≥ 3 GU toxicity is 3.4% (C) vs. 4.2% (H), RR = 1.26 (CI 0.69, 2.30). CONCLUSION In men with favorable-risk prostate cancer, long-term disease-free survival is non-inferior with 70 Gy in 28 fractions compared to 73.8 Gy in 41 fractions. The risk of BR is reduced with moderate hypofractionation. No differences in late Grade ≥3 GI/GU toxicity were observed between the arms. (ClinicalTrials.gov identifier: NCT00331773).

Abstract
OBJECTIVE Transcription factor 7-like 2 (TCF7L2) gene variants confer risk for type 2 diabetes and metabolic traits. We investigated the role of TCF7L2-variants in polycystic ovarian syndrome (PCOS), which is a common endocrine metabolic disorder affecting women of reproductive age. We tested whether TCF7L2 variants are in linkage to and/or in linkage disequilibrium [(LD), namely linkage and association)] with PCOS. PATIENTS AND METHODS Within 212 families from the Italian peninsular population, we analyzed 78 variants using Pseudomarker software for linkage to and LD with PCOS under the dominant model with complete penetrance (D1). In a secondary analysis, we tested the variants under the recessive models with complete penetrance (R1), dominant with incomplete penetrance (D2), and recessive with incomplete penetrance (R2). We tested through in silico analysis the risk variants to detect any potential functional effects. RESULTS We identified a total of 14 variants in the TCF7L2 gene significantly linked to and/or in LD with the risk of PCOS (p < 0.05) across different models. CONCLUSIONS This study is the first to report TCF7L2 linkage and linkage disequilibrium in Italian families with PCOS.

Abstract
BACKGROUND The outcomes of catheter ablation for atrial fibrillation in adults with congenital heart disease are not well described. METHODS In a retrospective study of adult patients with congenital heart disease who underwent catheter ablation for atrial fibrillation between 2000 and 2020 at Mayo Clinic, procedural characteristics and outcomes were collected. The primary outcomes were atrial arrhythmia (AA) recurrence following a 3-month blanking period and repeat ablation. An arrhythmia clinical severity score was assessed pre- and post-ablation based on the duration of arrhythmia episodes, symptoms, cardioversion frequency, and antiarrhythmic drug use. RESULTS One hundred forty-five patients (age, 57±12 years; 28% female; 63% paroxysmal atrial fibrillation) underwent 198 ablations with a median follow-up of 26 months (interquartile range, 14-69). One hundred ten, 26, and 9 patients had simple, moderate, and complex congenital heart disease, respectively. All patients underwent pulmonary vein isolation, and non-pulmonary vein targets were ablated in 79 (54%). AA recurrence at 12 months was 37% (95% CI, 29%-45%). On univariate analysis, increasing left atrial volume index was associated with higher odds of AA recurrence (odds ratio, 1.03 [1.00-1.06] per 1 mL/m2 increment; P=0.05). Noninducibility of atrial flutter was predictive of decreased odds of AA recurrence (odds ratio, 0.43 [0.21-0.90]; P=0.03). A second ablation was performed in 43 patients after a median of 20 (interquartile range, 8-37) months. Arrhythmia clinical severity scores improved following ablation, reflecting a decrease in symptoms, cardioversions, and antiarrhythmic drugs. CONCLUSIONS Catheter ablation of atrial fibrillation is feasible and effective in patients with adult congenital heart disease and reduces symptoms. Recurrence of AA frequently requires repeat ablation.

Abstract
OBJECTIVE The prolactin (PRL) system plays important behavioral, social, and metabolic roles, such as mediating social bonding and insulin secretion. Inherited dysfunction of the PRL pathway-related genes is associated with psychopathology and insulin resistance. We have previously suggested that the PRL system might be implicated in the comorbidity of psychiatric (depression) and type 2 diabetes (T2D) owing to the pleiotropy of PRL pathway-related genes. To our knowledge, no PRL variants have so far been reported in patients with either major depressive disorder (MDD) and/or T2D. PATIENTS AND METHODS In this study, we analyzed 6 variants within the PRL gene and tested them for the presence of parametric linkage and/or linkage disequilibrium (LD, i.e., linkage and association) with familial MDD, T2D, and their comorbidity. RESULTS We found, for the first time, that the PRL gene and its novel risk variants are linked to and in LD (i.e., linkage and association) with familial MDD, T2D, and MDD-T2D comorbidity. CONCLUSIONS PRL might play a key role in mental-metabolic comorbidity and can be considered a novel gene in MDD and T2D.

Abstract
OBJECTIVE Melatonin regulates the mammalian circadian rhythm and plays metabolic functions such as glucose homeostasis. Both melatonin receptors (MTNR1A and MTNR1B, encoded by the MTNR1A and MTNR1B genes, respectively) are expressed in pancreatic beta cells and mediate the glucometabolic roles of melatonin as well as insulin secretion. The MTNR1B gene is a well-known genetic risk factor in type 2 diabetes (T2D); however, little is known about the involvement of the MTNR1A gene in here T2D. We aimed to investigate whether MTNR1A is linked to and/or associated with familial T2D. SUBJECTS AND METHODS We genotyped 14 single nucleotide polymorphisms within the MTNR1A gene in 212 peninsular Italian families with T2D. We performed parametric linkage and linkage disequilibrium analyses to investigate the role of MTNR1A variants in conferring T2D risk. We considered variants statistically significant if conferring linkage or linkage disequilibrium with p < 0.05. RESULTS We found 3 novel variants (rs62350392, rs2119883, and rs13147179) significantly linked to and/or associated with T2D in multigenerational Italian families. CONCLUSIONS This is the first study to report MTNR1A as a novel risk gene in T2D. Functional studies are needed to confirm these results.

Abstract
OBJECTIVE The study evaluated the effect of Sapindus mukorossi (SM) extract as a final root canal irrigant on sealer penetration (SP) in dentinal tubules and microleakage. MATERIALS AND METHODS Samples were selected based on inclusion and exclusion criteria. An access opening in all samples was performed and the working length was decided using pro taper for canal finishing along with constant irrigation. Specimens were randomly divided into 3 groups. Group 1 was irrigated with 3 ml of 17% EDTA; group 2 was irrigated with SM irrigant and group 3 samples were irrigated with 0.9% saline. After obturation, samples were vertically placed in 1% methylene blue dye cut in half longitudinally, and viewed under a stereomicroscope. Analysis of SP in the dentinal tubule was assessed using scanning electron microscopy (SEM). For microleakage assessment, mean and standard deviation were reported and One-Way ANOVA was applied. SP was compared using Kruskal-Wallis' test. For inspecting the interaction between SM/EDTA and NaOCl, Fisher's exact test was applied. No statistically significant difference between microleakage in any of the tested groups was observed. The control group showed minimum leakage as compared to EDTA and SM. RESULTS The results displayed that there was no significant difference, (p=0.67), between dentinal tubule SP at 2 mm. A significant difference between dentinal tubule SP among groups at 5 mm was observed (p<0.05). CONCLUSIONS SM ethanolic extract showed comparable outcomes of smear layer removal and sealer penetration to 17% EDTA, as a final irrigant in root canal cleaning. Therefore, SM has the potential to be used as an adjuvant final irrigant in conjunction with NaOCl.

Abstract
OBJECTIVE Polycystic ovarian syndrome (PCOS) is a complex heterogeneous condition that affects women of reproductive age, conferring increased cardiovascular morbidity and mortality. The syndrome is characterized by oligomenorrhea, hyperandrogenism, and/or polycystic ovaries and is often associated with obesity and type 2 diabetes. Individuals are predisposed to PCOS by environmental factors and risk variants in genes mostly involved in ovarian steroidogenesis and/or insulin resistance. Genetic risk factors have been identified by both familial and genome-wide (GW) association studies. However, most genetic components are still unknown and missing heritability needs to be elucidated. To learn more about the genetic determinants of PCOS, we performed a GW study in genetically highly homogeneous peninsular families. PATIENTS AND METHODS We conducted the first GW-linkage and linkage disequilibrium (i.e., linkage + association) study in Italian families with PCOS. RESULTS We identified several novel risk variants, genes, and pathways potentially implicated in the pathogenesis of PCOS. Specifically, we detected 79 novel variants with significant GW-linkage and/or -association with PCOS across 4 inheritance models (p < 0.00005), of which 50 variants were within 45 novel PCOS-risk genes. CONCLUSIONS This is the first GW-linkage and linkage disequilibrium study performed in peninsular Italian families and reporting novel genes in PCOS.

Abstract
OBJECTIVE Oxytocin (OXT) controls appetite, promotes diet-induced energy expenditure, and may protect against obesity. Furthermore, the oxytocin system controls ovarian follicle luteinization and steroidogenesis as well as adrenal steroidogenesis, which if impaired might lead to anovulation and hyperandrogenism, signs found in women with polycystic ovarian syndrome (PCOS). PCOS is a common complex endocrine disorder of reproductive-age women, and it often presents with impaired glucose metabolism, insulin resistance (IR), and type 2 diabetes (T2D). The oxytocin receptor gene (OXTR) may confer a risk for PCOS, conceivably through dysregulation of metabolism, ovarian follicle maturation, and ovarian and adrenal steroidogenesis. Therefore, we aimed to investigate whether OXTR variants confer risk for PCOS. SUBJECTS AND METHODS In 212 Italian subjects with T2D and PCOS, we have analyzed 22 single nucleotide polymorphisms (SNPs) within the OXTR gene for linkage to and/or linkage disequilibrium (LD, i.e., association) with PCOS. We tested whether the significant risk variants were independent or part of an LD block. RESULTS We found 5 independent variants significantly linked to/in LD with PCOS within the peninsular families. CONCLUSIONS This is the first study to report OXTR as a novel risk gene in PCOS. Functional and replication studies are needed to confirm these results.

Abstract
OBJECTIVE Polycystic ovarian syndrome (PCOS) is a complex heterogeneous disorder characterized by hyperandrogenism, irregular menses, and subfertility and often accompanied by other related comorbid disorders such as insulin resistance, obesity, and type 2 diabetes. Several genetic risk factors predispose to PCOS, but most are still unknown. Up to 30% of women with PCOS may have hyperaldosteronism. Blood pressure and the ratio of blood levels of aldosterone to renin are higher in women with PCOS compared to healthy controls, even if still in the normal range; and the aldosterone antagonist spironolactone has been used as therapy for PCOS, mainly due to its antiandrogenic activity. Thus, we aimed to investigate the potential pathogenetic role of the mineralocorticoid receptor gene (NR3C2) as the encoded NR3C2 product binds aldosterone and plays a role in folliculogenesis, fat metabolism, and insulin resistance. SUBJECTS AND METHODS Within 212 Italian families with T2D and phenotyped for PCOS, we analyzed 91 single nucleotide polymorphisms in the NR3C2 gene. We tested the NR3C2 variants for linkage and linkage disequilibrium to the PCOS phenotype by using parametric analysis. RESULTS We found 18 novel risk variants significantly linked to and/or associated with the risk of PCOS. CONCLUSIONS We are the first to report NR3C2 as a risk gene in PCOS. However, our findings need to be replicated in other ethnic groups in order to reach more solid conclusions.

Abstract
INTRODUCTION Catheter ablation for atrial fibrillation (AF) is frequently used for the purpose of rhythm control and improved quality of life (QoL). Although success rates are high, a significant proportion of patients require redo ablation. Data are scarce on patient-centered outcomes and QoL in patients undergoing redo AF ablation. We aimed to assess QoL and clinical outcomes using a large prospectively maintained patient-reported outcomes (PRO) registry. METHODS All patients undergoing redo AF ablation (2013-2016) at our center were enrolled in a prospective registry for outcomes and assessed for QoL using automated PRO surveys (baseline, 3 and 6 months after ablation, every 6 months thereafter). Data were collected over 3 years of follow-up. The atrial fibrillation symptom severity scale (AFSSS) was used as the main measure for QoL. Additional variables included patient-reported improvement, AF burden, and AF-related healthcare utilization including emergency room (ER) visits and hospitalizations. RESULTS A total of 848 patients were included (28% females, mean age 63.8, 51% persistent AF). By automated PRO, significant improvement in QoL was noted (baseline median AFSSS of 12 [5-18] and ranged between 2 and 4 on subsequent assessments; p < .0001), with ≥70%of patients reported remarkable improvement in their AF-related symptoms. The proportion of patients in AF at the time of baseline survey was 36%, and this decreased to <8% across all time points during follow-up (p < .0001). AF burden was significantly reduced (including frequency and duration of episodes; p < .0001), with an associated decrease in healthcare utilization after 6 months from the time of ablation (including ER visits and hospitalizations; p < .0001). The proportion of patients on anticoagulants or antiarrhythmics decreased on follow-up across all time points (p < .0001 for all variables). CONCLUSION Most patients derive significant QoL benefit from redo AF ablation; with reduction of both AF burden and healthcare utilization.

Abstract
OBJECTIVE Alterations in the activity of the transcription factor 7-like 2 (TCF7L2) generate defects previously associated with neuropsychiatric disorders. We investigated the role of the TCF7L2 gene in major depressive disorder (MDD), type 2 diabetes (T2D), and MDD-T2D comorbidity. We tested whether TCF7L2 is in linkage to and/or in linkage disequilibrium (LD, namely association) with MDD, T2D, and MDD-T2D. PATIENTS AND METHODS In 212 families with T2D and MDD in the Italian population, we analyzed 80 microarray-based SNPs using Pseudomarker software for linkage to and LD with T2D and MDD under the recessive model with complete penetrance (R1). In a secondary analysis, we tested the variants under the dominant models with complete penetrance (D1), recessive with incomplete penetrance (R2), and recessive with incomplete penetrance (R2). RESULTS We found several novel linkage signals and genetic associations. In addition, we found two new transcription-factor (TF) binding sites created by two risk variants found: the MDD-risk variant rs12255179 creates a new TF-binding site for the CCAAT/enhancer-binding protein α (C/EBPα), and the T2D-risk variant rs61872794 creates a new TF-binding site for the organic cation-uptake transporter (OCT1). Both new binding sites are related to insulin metabolism. CONCLUSIONS These results highlight the cross-interactivity between T2D and MDD. Further replication is needed in diverse ethnic groups.

Abstract
OBJECTIVE PSMD9 is a ubiquitous protein present at high concentrations in eukaryotic cells. It contributes to the degradation of intracellular proteins in the immune system. It is part of the 26S proteasome complex, and its regulatory role on proteasomal activity as well as its effect on genetic transcription have been recognized. PSMD9 has been related with insulin secretion, and it regulates the ligand-dependent retinoid-target genes transcription. Importantly, PSMD9 rs74421874 (IVS3+nt460-G>A), rs3825172 (IVS3+nt437-C>T), and rs14259 SNPs have been previously linked to type 2 diabetes (T2D), maturity-onset diabetes of the young 3 (MODY3), overweight status and waist circumference, hypertension, hypercholesterolemia, cardiovascular disease, microvascular disease (retinopathy, neuropathy, and nephropathy), carpal tunnel syndrome, depression, anxiety, insomnia, and sleep hours. MATERIALS AND METHODS In this study, we analyzed the above-mentioned PSMD9 rs74421874 (IVS3+nt460-G>A), rs3825172 (IVS3+nt437-C>T), and rs14259 SNPs for linkage to the T2D quantitative traits of T2D age of onset, duration in years of combined oral hypoglycemic agents and insulin therapy and only insulin therapy, stress, and the birth weight of the subjects' children; and with the T2D qualitative phenotypes of irregular menses, couple infertility, and menopausal hot flashes. RESULTS We found that PSMD9 was linked to irregular menses of reproductive age, menopausal hot flashes, T2D age of onset, years of combined oral and insulin therapy and of insulin therapy; we also found that it shows only a tendency towards linkage to stress, birthweight, and couple infertility. CONCLUSIONS This is the first time that this gene is implicated with irregular menses of reproductive age (a trait of polycystic ovarian syndrome), hot flashes, T2D onset age, and duration years of combined oral and insulin therapy and only insulin therapies.

Abstract
OBJECTIVE The dopamine receptor 2 (DRD2) binds dopamine in both central tissues (e.g., basal ganglia, pituitary gland) and peripheral tissues (e.g., adrenal gland, kidneys, intestine) and mediates dopamine actions in cognition, emotional processing, and prolactin-secretion inhibition and stimulation, and in DRD2-/- knockout mice insulin secretion is impaired. Variants in or around the DRD2 gene have been implicated in major depressive disorder (MDD), schizophrenia, obesity, and type 2 diabetes (T2D) but not in comorbid MDD-T2D patients; DRD2 agonists (e.g., bromocriptine) are approved treatments in T2D. This study aimed to detect whether the DRD2 gene plays a role in T2D, MDD, and T2D-MDD comorbidity in Italian families. SUBJECTS AND METHODS In 212 Italian families with T2D and MDD, we investigated the presence of linkage and linkage disequilibrium of variants in the DRD2 gene with T2D and/or MDD. A test was considered statistically significant if p was <0.05. RESULTS We found 3 novel variants (rs6276, rs35608204, and rs1800499) significantly linked to and/or associated with the risk of T2D and 1 novel variant (rs112646785) significantly linked and associated to the comorbidity of T2D and MDD. CONCLUSIONS This is the first study to link and associate DRD2 variants with the comorbidity of T2D and MDD.

Abstract
Abstract
Background
Previous research on period effects in risk for work disability due to common mental disorders across employment sectors and occupational classes in young employees is lacking. Temporal changes in the healthcare system or social insurance policies or other structural/organisational changes could contribute to such time period effects. We aimed to investigate time period effects in the risk of work disability, defined as long-term sickness absence (LTSA) and disability pension (DP) due to common mental disorders (CMDs), among young employees according to their employment sector (private/public) and occupational class (non-manual/manual).
Methods
Three cohorts, including all employed individuals with complete information on employment sector and occupational class, aged 19-29 years and resident in Sweden on the 31-Dec-2004, 2009 and 2014 (n = 573,516, 665,138 and 600,889 individuals in cohort 2004, 2009 and 2014, respectively) were followed for four years. Crude and multivariate-adjusted hazard ratios (HRs and aHRs, respectively) with 95% confidence intervals (CIs) were estimated regarding the risk of LTSA and DP due to CMDs using Cox regression analyses.
Results
In cohort 2004, public sector employees had a higher relative risk for LTSA due to CMDs than private sector employees (aHR, (95%CI): 1.24, 1.16-1.34 and 1.18, 1.11-1.26 among non-manual and manual workers). These associations were similar in the later cohorts. Compared to cohort 2004, the rate of DP due to CMDs was considerably lower in the later cohorts leading to uncertainties in the risk estimates limiting the comparability for time period effects regarding the risk of DP due to CMDs across employment sectors and occupational classes.
Conclusions
Stricter regulation changes regarding the receipt of DP in Sweden, rather than other time period events, may have differentially affected the risk of work disability among young non-manual and manual employees working in the private and public sectors.

Abstract
ObjectiveThe Hunter-8 prehospital stroke scale predicts large vessel occlusion in hyperacute ischemic stroke patients (LVO) at hospital admission. We wished to test its performance in the hands of paramedics as part of a prehospital triage algorithm. We aimed to determine a) the proportion of patients identified by the Hunter-8 algorithm, receiving reperfusion therapies, b) whether a call to stroke team improved this, and c) performance for LVO detection using an expanded LVO definition.MethodsA prehospital workflow combining pre-morbid functional status, time from symptom onset, and the Hunter-8 scale was implemented from July 2019. A telephone call to the stroke team was prompted for potential treatment candidates. Classic LVO was defined as a proximal middle cerebral artery (MCA-M1), terminal internal carotid artery, or tandem occlusion. Extended LVO added proximal MCA-M2 and basilar occlusions.ResultsFrom July 2019 to April 2021, there were 363 Hunter-8 activations, 320 analysed: 181 (56.6%) had confirmed ischemic strokes, 13 (4.1%) transient ischemic attack, 91 (28.5%) stroke mimics, and 35 (10.9%) intracranial haemorrhage. Fifty-two patients (16.3%) received reperfusion therapies, 35 with Hunter-8 ≥ 8. The stroke doctor changed the final destination for 76 patients (23.7%), and five received reperfusion therapies. The AUCs for classic and extended LVO were 0.73 (95% CI 0.66-0.79) and 0.72 (95% CI 0.65-0.77), respectively.ConclusionThe Hunter-8 workflow resulted in 28.7% of confirmed ischemic stroke patients receiving reperfusion therapies, with no secondary transfers to the comprehensive stroke centre. The role of communication with stroke team needs to be further explored.

Abstract
Background Data on percutaneous left atrial appendage closure (LAAC) outcomes in the very elderly with atrial fibrillation are limited. We aimed to investigate the clinical characteristics and short‐term outcomes of patients 80 years or older following percutaneous LAAC in a large nationwide database. Methods and Results Using the Nationwide Readmissions Database, we identified patients who underwent percutaneous LAAC between January 2016 and December 2018. Patients were categorized based on age (≥80 and <80 years old). The primary outcome was in‐hospital mortality. Secondary outcomes were in‐hospital end points including periprocedural complications, 30‐day outcomes, and all‐cause 30‐day readmissions. A propensity score–matched model (1:1) was used to adjust for baseline characteristics among the study groups. A total of 13 208 patients were included in this study (43% women, median age in years [interquartile range] 79.5 [73–84]) and matched one‐to‐one (6604 and 6604 patients were ≥80 and <80 years old, respectively). In‐hospital mortality was not statistically different between the study groups and occurred in 21 patients ≥80 years old (0.32%) and in 14 patients <80 years old (0.21%); P=0.236. Rates of in‐hospital stroke/transient ischemic attack were higher in patients ≥80 years old compared with those <80 years old (1.22% versus 0.77%; P=0.009). In‐hospital bleeding requiring transfusion, vascular complications, systemic embolization, and pericardial effusion/tamponade requiring pericardiocentesis or surgical intervention occurred more frequently in patients ≥80 years old. Furthermore, the elderly group was more likely to be readmitted within 30 days compared with those <80 years old (9.91% versus 8.4%; P=0.004); however, rates of 30‐day complications were not statistically different between the study groups. Conclusions In a large nationwide database, patients ≥80 years old undergoing percutaneous LAAC were found to have similar in‐hospital mortality but an increased risk of periprocedural complications and 30‐day readmission compared with younger patients. Our data suggest that LAAC should be considered on a case‐by‐case basis in the very elderly, taking into consideration the risks and benefits of this intervention. Further studies are needed to assess long‐term LAAC outcomes in this high‐risk population.

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
Abstract
Study question
How completely reported are studies on blood biomarkers of endometriosis, according to their adherence to the STARD 2015 checklist?
Summary answer
Studies on blood biomarkers of endometriosis are often incompletely reported, with only an overall adherence rate of 28.5% to the STARD 2015 checklist.
What is known already
Laparoscopy, the gold standard diagnostic method for determining endometriosis, is invasive, expensive, requires anesthesia and is associated with risk of vascular/ visceral damage. Therefore, less invasive diagnostics are needed. Many studies have been published on blood biomarkers of endometriosis with variable methodological quality. To assess applicability and risk of bias of diagnostic accuracy studies, completeness of study reporting must first be ensured. STARD 2015 checklist was introduced to guide reporting of diagnostic accuracy studies. The degree of adherence in studies on blood biomarkers of endometriosis to this 30-item STARD 2015 checklist is not known.
Study design, size, duration
Our systematic review included 126 studies from the 2016 Cochrane review on blood biomarkers of endometriosis. We added 84 more studies after updating the search in Pubmed, CINHAL and Web of Science, for the period May 2015- July 2021, with the keywords: endometriosis and biomarkers/ non-invasive diagnosis/ laboratory tests/ blood test, using the same eligibility criteria as in the Cochrane review. Totally, 210 studies were assessed for adherence to STARD 2015 checklist.
Participants/materials, setting, methods
STARD 2015 items were scored 1 if reported, or 0 if unreported. Each study received an adherence rate (percent of reported STARD items). Every item received individual item’s reporting rate (percent of its reporting across studies). Effect of publication year on study adherence and item reporting rates was examined by linear and logistic regressions, respectively. Journal impact factors were classified to tertiles and their relation to study adherence rate examined with one-way ANOVA.
Main results and the role of chance
Adherence rate was 28.5%, with 8.8± 3.1 reported items per study (range 2-18). Study adherence to STARD 2015 significantly increased with advancing publication years [r = 0.344 (95% CI 0.219 – 0.458), p < 0.001]. Journal impact factor had no effect on adherence to STARD 2015 (P = 0.274). Items with reporting rates >50% included #1 (identification as diagnostic accuracy study), #5 (prospective or retrospective), #7 (participants identification), #10a (index test), #10b (reference standard), #14 (diagnostic accuracy measures), #21a (disease severity), #21b (alternate diagnosis), and #22 (time between index test and reference standard). Items with reporting rates 20 to 50% included #6 (eligibility criteria), #8 (when/ where participants identifies), #12a (test positivity cutoff), #20 (participant characteristics) and #26 (limitations). Reporting rate < 20% seen in items #3 (background), #4 (hypothesis), #9 (consecutive /random recruitment), #13a/b (blinding of index test/ reference standard performers), #15 (intermediate results), #16 (missing data), #17 (analysis of variability), #18 (sample size), #19 (flow diagram), #23 (cross tabulation), #24 (diagnostic accuracy precision), #25 (adverse events), #27 (implications), #28 (registration), #29 (protocol), #30 (funding). Reporting improved for items: #1, #8, #10a, #10b, #12a, #14, #17, #18, #19, #20 and #25 and declined for items #9, #21a and #27 over publication years.
Limitations, reasons for caution
As the consequence of our choice to adhere to the methodology of the original Cochrane review, a limitation of our study is that we excluded non-English language studies and limited the search to the previously chosen 3 databases only.
Wider implications of the findings
With inadequately reported diagnostic accuracy studies, the derived evidence can be misleading. Our findings represent a baseline evaluation of the reporting status of studies on blood biomarkers of endometriosis. Our results can guide researchers and editors about poorly reported STARD 2015 items, aiming to improve their future reporting quality.

Abstract
BACKGROUND Optimal management of cardiac implantable electronic devices (CIEDs) in patients with Ebstein anomaly during tricuspid valve (TV) surgery is unknown. Thus, we aimed to characterize CIED management/outcomes in patients with Ebstein anomaly undergoing TV surgery. METHODS Patients at the Mayo Clinic from 1987 to 2020 with Ebstein anomaly and CIED procedure were reviewed for procedural details, complications, echocardiogram, and lead parameters. Five-year cumulative incidence of CIED complications were estimated using the Kaplan-Meier method. RESULTS Ninety-three patients were included; 51 were female, and mean age was 40.7±17.5 years. A new CIED was implanted in 45 patients at the time of TV surgery with the majority receiving an epicardial (n=37) CIED. Among 34 patients who had preexisting CIED (11 epicardial, 23 transvenous) at time of TV surgery, 20 had a transvenous right ventricular lead managed by externalizing the lead to the TV (n=15) or extracting the transvenous lead with epicardial lead implantation (n=5). Fourteen patients underwent CIED implantation (4 epicardial, 10 transvenous) without concurrent surgery. Placement of lead across the TV was avoided in 85% of patients. The 5-year cumulative incidence of CIED complications was 24% with no significant difference between epicardial and transvenous CIEDs (26% versus 23%, P=0.96). Performance of lead parameters was similar in epicardial and transvenous leads during median (interquartile range) follow-up of 44.5 (61.1) months. CONCLUSIONS In patients with Ebstein anomaly undergoing TV surgery, the use of epicardial leads and externalization of transvenous leads to the TV can avoid lead placement across the valve leaflets. Lead performance and CIED complications was similar between epicardial and transvenous CIEDs.

Abstract
Introduction The corticotropin-releasing hormone receptor 2 (CRHR2) gene encodes CRHR2, which is an important element in the hypothalamic-pituitary-adrenal physiologic response towards stress culminating in hyperglycemia, insulin resistance, mood disorders and depression (MDD). CRHR2-/- mice are hypersensitive to stress, and the CRHR2 locus in humans has been linked to type 2 diabetes (T2D) and MDD. Objectives Several variants in the CRHR2 gene have been reported in patients with bipolar disorder, post-traumatic stress disorder, and T2D, but variants in the gene have not been investigated in families with T2D and MDD. Methods We genotyped 212 Italian families with T2D and MDD. We tested 17 SNPs in the CRHR2 gene using two-point parametric-linkage and linkage-disequilibrium (LD) analysis with the following models: dominant with complete-penetrance (D1), dominant with incomplete-penetrance (D2), recessive with complete-penetrance (R1) and recessive with incomplete-penetrance (R2). Results We detected linkage to and/or LD with: MDD for 3 SNPs/D1, 2 SNPs/D2, 3 SNPs/R1, and 3 SNPs/R2; and, T2D for 3 SNPs/D1, 2 SNPs/D2, 2 SNPs/R1 and 1 SNP/R2. Two independent SNPs were comorbid. Interestingly, the variants linked to or in LD with MDD had in general higher statistical significance level than the variants linked to T2D, despite that the families were primarily ascertained for T2D. Conclusions Our study shows for the first time that the CRHR2 gene which encodes CRHR2 is in linkage to and linkage disequilibrium with MDD and T2D, thereby contributing, in families with T2D, to both disorders and underlying the shared genetic pathogenesis of their comorbidity Disclosure No significant relationships.

Abstract
This article describes the environmental impacts of producing a single seedling in forest nurseries of selected districts (i.e., Haripur, Abbottabad, and Mansehra) of Hazara Division of Khyber Pakhtunkhwa, Pakistan using the life cycle assessment (LCA) approach. This study was based on the cradle-to-gate approach which begins with the pre-nursery stage and progresses toward the main nursery before transplanting seedlings into the plantation site. Data or life cycle inventory (LCI) of seedling production were collected through questionnaire surveys and personal meetings with forest nurseries managers and workers regarding consumption of different inputs such as electricity, diesel, fertilizers, herbicides, and polyethylene bags, organic manure, and water consumption. The SimaPro software version 8.5 and the CML2000 v2.05 environmental model was applied to perform life cycle impact assessment (LCIA) for a single seedling production in forest nurseries in the study area. In line with the objectives of the study, primary data regarding inputs and outputs of the nurseries were collected from 35 nurseries in the study area by using a random questionnaire method. In addition, secondary data were taken from online databases such as Eco-invent v.3.2 CORRIM and peer-reviewed published literature. For this study, a functional unit of a single seedling was considered. Production weighted average data were modeled in the latest environmental modeling software i.e., SimaPro v.8.5 for ten US-EPA most wanted environmental impacts, such as global warming potential (GWP), abiotic depletion (AD), eutrophication potential (EP), acidification potential (AP), freshwater aquatic eco-toxicity (FAE), marine water eco-toxicity (MWE), terrestrial eco-toxicity (TE), ozone layer depletion (OLD), photochemical oxidation (PO), and human toxicity (HT). The results showed that the highest environmental impact posed by a single seedling was marine aquatic eco-toxicity (11.31360 kg 1,4-DB eq), followed by global warming potential (0.02945 kg CO2 eq) and (0.01227 kg 1,4-DB eq) human toxicity. The primary reason for these environmental burdens was the use of synthetic fertilizers in forest nurseries and the consumption of fossil fuels in nursery mechanization and transportation activities. The total cumulative energy demand for a single seedling was (0.800 MJ) with more than 90% contribution from fossil fuel energy resources such as petrol and diesel. It is therefore highly recommended to use renewable energy resources and organic fertilizers instead of chemical fertilizers in forest nurseries to avoid and minimize greenhouse gas emissions (GHS) and other toxic emissions in the study area.

Abstract
OBJECTIVE Intracranial complications of sinusitis and acute otitis media (AOM) are rare but life-threatening events. In children with suppurative intracranial complications, concurrent neurosurgical and otolaryngological (ORL) intervention has been recommended to optimize outcomes. The aim of this study was to investigate outcomes following concurrent neurosurgical and ORL intervention. METHODS A retrospective cohort study of children undergoing neurosurgical intervention for intracranial complications of sinusitis or AOM in two neurosurgical centres in Ireland was conducted. RESULTS 65 children were identified. Mean age was 11.9 years. The most prevalent symptoms were headache, pyrexia, altered level of consciousness, facial swelling, and vomiting. Subdural empyema (n = 24, 36.9%) and extradural abscess (n = 17, 26.2%) were the most common complications. 54 underwent same admission ORL intervention; 47 (87%) were performed concurrently or earlier. For rhinogenic infections, 35 (64.8%) underwent endoscopic sinus surgery (ESS), 13 (24.1%) underwent frontal sinus trephine, and 5 (9.3%) underwent maxillary sinus washout alone. For otogenic infections, 10 (90.9%) underwent mastoidectomy and 7 (63.6%) underwent tympanostomy tube placement. 19 (29.2%) had post-operative neurological deficits, of which 2 (3.1%) were permanent. Streptococcus intermedius was the most common pathogen (n = 30, 46.2%). Concurrent intervention reduced the prevalence of residual collection (p = 0.018) and the need for revision neurosurgical intervention (p = 0.039) for sinogenic complications. The same trends did not achieve statistical significance for the otogenic group. Mortality was 0%. CONCLUSION Intracranial complications of sinusitis and AOM are best managed in a specialist centre with multidisciplinary input. Concurrent ORL and neurosurgical intervention reduces abscess recurrence and requirement for revision neurosurgery in sinogenic complications and should represent the standard of care. ESS is the ORL modality of choice in experienced hands.

Abstract
BACKGROUND In a bid to end the ongoing coronavirus disease 2019 pandemic, many countries, including the UK, have rolled out mass immunisation programmes. While considered generally safe and effective, vaccines against coronavirus disease 2019 have been reported to be associated with rare and potentially adverse reactions and side effects. CASE REPORT This paper reports an unusual case of a patient who developed a unilateral vocal fold paralysis shortly after receiving the first dose of the Oxford-AstraZeneca ChAdOx1 nCov-19 vaccine. CONCLUSION To our knowledge, this is the first reported case of vocal fold paralysis following administration of the Oxford-AstraZeneca vaccine. The authors support the position that currently approved coronavirus disease 2019 vaccines remain safe and effective; however, further surveillance and vigilance using real-world data are highly encouraged.

Abstract
Particulate matter (PM) is a major air pollutant causing serious health problems. The aim of the present study was to find out concentration of PM in ambient air and its associated health risk in Haripur city, Pakistan. Twenty-three samples were taken at various educational institutes, hospitals, recreational areas and industries in Haripur city. Concentration of PM2.5 (µg/m3) and PM10 (µg/m3) was measured with Youngteng YT-HPC 3000A portable PM counter. The results revealed that values of both PM2.5 and PM10 were above the permissible limits (35 µg/m3 for PM2.5 and 150 µg/m3 for PM10) set by Environmental Protection Agency Pakistan (Pak-EPA) in all the educational institutes, hospitals, recreational areas and industries investigated. Furthermore, significant (p<0.05) variation was found in the concentration of both PM2.5 and PM10 in all the educational institutes, hospitals, recreational areas, and industries studied. The concentration of PM2.5 was positively correlated with the concentration of PM10 in all the sampling sites. Therefore, from 1-14 scale standard of health index, the values of PM2.5 and PM10 exhibited that the ambient air quality of Haripur city Pakistan is under high risk. If the regulatory authorities such as Environmental Protection Agency, Health Department and Local Government monitor PM pollution in different settings of Haripur city, then a decrease can be possible in the pollution level. The remedies that can be taken to overcome the problem of ambient air pollution such as PM are plantation of trees at the sites where there are higher levels of air pollutants and use of masks on personal protection basis along with implementation of pollution control system in industries of Hattar Industrial Estate Haripur city, Pakistan.

Abstract
Abstract
Aim
In June 2020, and after the first wave of the COVID outbreak has settled, we resumed operating in our trust for elective surgery in three different hospitals. However, it was thought that the number of post-tonsillectomy complications had increased. We performed an audit to evaluate the rate of post-tonsillectomy complications in our trust and investigate possible causes.
Method
We measured the rates of patients who developed complications post-operatively during the period from June to November 2020 and compared it to the rates in the pre-COVID year and the national rate. Moreover, we scrutinized retrospectively the operative notes of each patient presenting with a post-tonsillectomy complication and identified risk factors.
Results
In the study period, we performed 129 tonsillectomies. Of these patients, 14 presented with complications; 11of which had bleeding, while 3 had post-operative pain. Two patients needed to return to the theatre to control the bleeding. During the same period in 2019, 28 patients had complications out of a total of 199 patients. The rate of complications in 2020 was 10% which compared favourably with the previous year (14%). The highest number of patients (9/14) was in a hospital which posed a new environment to our surgeons. Dissection by Bipolar diathermy was the most contribute factor for bleeding in most patients (11/14).
Conclusions
The disruption caused by the pandemic situation did not influence overall rates of complications. However, the hospital which presented a new operating environment had the highest rate.

Abstract
Carbon nanomaterials have gained significant interest over recent years in the field of electrochemistry, and they may be limited in their use due to issues with their difficulty in dispersion. Enzymes are prime components for detecting biological molecules and enabling electrochemical interactions, but they may also enhance multiwalled carbon nanotube (MWCNT) dispersion. This study evaluated a MWCNT and diamine oxidase enzyme (DAO)-functionalised screen-printed electrode (SPE) to demonstrate improved methods of MWCNT functionalisation and dispersion. MWCNT morphology and dispersion was determined using UV-Vis spectroscopy (UV-Vis) and scanning electron microscopy (SEM). Carboxyl groups were introduced onto the MWCNT surfaces using acid etching. MWCNT functionalisation was carried out using 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (EDC) and N-Hydroxysuccinimide (NHS), followed by DAO conjugation and glutaraldehyde (GA) crosslinking. Modified C-MWNCT/EDC-NHS/DAO/GA was drop cast onto SPEs. Modified and unmodified electrodes after MWCNT functionalisation were characterised using optical profilometry (roughness), water contact angle measurements (wettability), Raman spectroscopy and energy dispersive X-ray spectroscopy (EDX) (vibrational modes and elemental composition, respectively). The results demonstrated that the addition of the DAO improved MWCNT homogenous dispersion and the solution demonstrated enhanced stability which remained over two days. Drop casting of C-MWCNT/EDC-NHS/DAO/GA onto carbon screen-printed electrodes increased the surface roughness and wettability. UV-Vis, SEM, Raman and EDX analysis determined the presence of carboxylated MWCNT variants from their non-carboxylated counterparts. Electrochemical analysis demonstrated an efficient electron transfer rate process and a diffusion-controlled redox process. The modification of such electrodes may be utilised for the development of biosensors which could be utilised to support a range of healthcare related fields.

Abstract
Life cycle assessment was carried out for a conventional wooden furniture set produced in Mardan division of the Khyber Pakhtunkhwa province of Pakistan during 2018-19. Primary data regarding inputs and outputs were collected through questionnaire surveys from 100 conventional wooden furniture set manufacturers, 50 in district Mardan and 50 in district Swabi. In the present study, cradle-to-gate life cycle assessment approach was applied for a functional unit of one conventional wooden furniture set. Production weighted average data were modelled in the environmental impacts modelling software i.e., SimaPro v.8.5. The results showed that textile used in sofa set, wood preservative for polishing and preventing insects attack and petrol used in generator had the highest contribution to all the environmental impact categories evaluated. Total cumulative energy demand for wooden furniture set manufactured was 30,005 MJ with most of the energy acquired from non-renewable fossil fuel resources.

Abstract
Direct oral anticoagulants (DOACs) can potentially interact with multiple prescription medications. We examined the prevalence of co-prescription of DOACs with interacting medications and its impact on outcomes in patients with atrial fibrillation (AF). Patients with AF treated with a DOAC from 2010 to 2017 at the Mayo Clinic and co-prescribed medications that are inhibitors or inducers of the P-glycoprotein and/or Cytochrome P450 3A4 pathways were identified. The outcomes of stroke, transient ischemic attack, or systemic embolism, major bleeding, and minor bleeds were compared between patients with and without an enzyme inducer. Cox proportional hazards model was used to assess the association between interacting medications and outcomes. Of 8,576 patients with AF (mean age 70 ± 12 years, 35% female) prescribed a DOAC (38.6% apixaban, 35.8% rivaroxaban, 25.6% dabigatran), 2,610 (30.4%) were on at least 1 interacting agent: the majority were on an enzyme inhibitor (n = 2,592). Prescribed medications included non-dihydropyridine calcium channel blocker (n = 1,412; 16.5%), antiarrhythmic medication (n = 790; 9.2%), antidepressant (n = 659; 7.7%), antibiotic/antifungal (n = 77; 0.90%), antiepileptics (n = 17; 0.2%) and immunosuppressant medications (n = 19; 0.2%). Patients on an interacting medication were more likely to receive a lower dose of DOAC than indicated by the manufacturer's labeling (15.0% vs 11.4%, p <0.0001). In multivariable analysis, co-prescription of an enzyme inhibitor was not associated with risk of any bleeding (hazard ratio 0.87 [0.71 to 1.05], p = 0.15) or stroke, transient ischemic attack, or systemic embolism (hazard ratio 0.82 [0.51 to 1.31], p = 0.39). In conclusion, DOACs are co-prescribed with medications with potential interactions in 30.4% of patients with AF. Co-prescription of DOACs and these drugs are not associated with increased risk of adverse embolic or bleeding outcomes in our cohort.

Abstract
This study aimed to develop and evaluate data driven models for prediction of forest yield under different climate change scenarios in the Gallies forest division of district Abbottabad, Pakistan. The Random Forest (RF) and Kernel Ridge Regression (KRR) models were developed and evaluated using yield data of two species (Blue pine and Silver fir) as an objective variable and climate data (temperature, humidity, rainfall and wind speed) as predictive variables. Prediction accuracy of both the models were assessed by means of root mean squared error (RMSE), mean absolute error (MAE), correlation coefficient (r), relative root mean squared error (RRMSE), Legates-McCabe's (LM), Willmott's index (WI) and Nash-Sutcliffe (NSE) metrics. Overall, the RF model outperformed the KRR model due to its higher accuracy in forecasting of forest yield. The study strongly recommends that RF model should be applied in other regions of the country for prediction of forest growth and yield, which may help in the management and future planning of forest productivity in Pakistan.

Abstract
Abstract
Introduction/Objective
High take-off coronary arteries (HTO) are defined by coronary ostia arising above the sinotubular junction (STJ). Although asymptomatic in most individuals, there is increasing evidence that HTO is a risk factor for sudden cardiac death. Here we present two patients where HTO contributed to death.
Methods/Case Report
Patient A was a 52 year old morbidly obese male with atypical chest pain, new inferior ST elevations and troponinemia. Multiple coronary angiographies did not reveal any stenosis, but 3 stents were placed in the RCA due to concern for vasospasm. 3 days later the patient died. Autopsy revealed cardiac tamponade and non- atherosclerotic ischemic heart disease with remote apical LV scar and diffuse patchy interstitial fibrosis in the myocardium, which could be attributed to HTO of the RCA 0.5 cm above the STJ and early intramuscular courses of both coronaries. Multiple angiographies likely caused iatrogenic coronary injury and subsequent tamponade. Patient B was a healthy 33 year old female at 34 weeks gestation, who developed anaphylaxis during IV iron infusion for severe iron deficiency anemia. She was transferred to the OR for emergent C-section. Minutes after delivery she died. Autopsy revealed HTO, with coronary ostia being 0.4 cm and 0.7 cm above the STJ, respectively and acute angle take-off of LCA. No atherosclerosis was noted. The inability to increase myocardial perfusion through the coronary arteries during a high stress situation due to pregnancy, iron deficiency anemia and anaphylaxis likely contributed to lethal myocardial ischemia.
Results (if a Case Study enter NA)
NA
Conclusion
HTO and other coronary artery anomalies (CAAs) should be considered in cases of cryptogenic acute and chronic myocardial ischemia. Hemodynamic characterization of HTO, including those < 1 cm above the STJ in presence and absence of other CAAs may help better understand their pathophysiologic significance. Antemortem diagnosis requires high clinical suspicion and appropriate surgical intervention could be life-saving.

Abstract
BACKGROUND While ventricular tachycardia (VT) in the setting of postmyocardial infarction left ventricular aneurysms (LVA) is not uncommonly encountered, there is a scarcity of data regarding the safety, efficacy, and outcomes of ablation of VT in this subset of patients. METHODS Our study included consecutive patients aged 18 years or older with postmyocardial infarction LVA who presented to Mayo Clinic for catheter ablation of VT between 2002 and 2018. RESULTS Of 34 patients, the mean age was 70.4 ± 9.1 years; 91% were male. Mean LVEF was 29 ± 9.7% and left ventricular end-diastolic dimension was 64.9 ± 6.6 mm. The site of the LVA was apical in 21 patients (62%). Fifteen patients (44%) presented with electrical storm or incessant VT. Nine patients (26%) had a history of intracardiac thrombus. All except for one patient had at least one VT originating from the aneurysm. The mean number of VTs was 2.9 ± 1.7. All patients underwent ablation at the site of the aneurysm. Ablation outside the aneurysm was performed in 13 patients (38%). Low-voltage fractionated potentials and/or late potentials at the aneurysmal site were present in all cases. Complete elimination of all VTs was achieved in 18 (53%), while the elimination of the clinical VT with continued inducibility of nonclinical VTs was achieved in a further 11 patients (32%). Two patients developed cardiac tamponade requiring pericardiocentesis. During a mean follow-up period of 2.3 ± 2.4 years, 11 patients (32%) experienced VT recurrence. Freedom from all-cause mortality at 1-year follow-up was 94%. CONCLUSION Radiofrequency catheter ablation targeting the aneurysmal site is a feasible and reasonably effective management strategy for clinical VTs in patients with postinfarction LVA.

Abstract
OBJECTIVE To evaluate the effectiveness and adverse events of autologous platelet-rich plasma (PRP) in individuals with lower-extremity diabetic ulcers, lower-extremity venous ulcers, and pressure ulcers. PATIENTS AND METHODS We searched multiple databases from database inception to June 11, 2020, for randomized controlled trials and observational studies that compared PRP to any other wound care without PRP in adults with lower-extremity diabetic ulcers, lower-extremity venous ulcers, and pressure ulcers. RESULTS We included 20 randomized controlled trials and five observational studies. Compared with management without PRP, PRP therapy significantly increased complete wound closure in lower-extremity diabetic ulcers (relative risk, 1.20; 95% CI, 1.09 to 1.32, moderate strength of evidence [SOE]), shortened time to complete wound closure, and reduced wound area and depth (low SOE). No significant changes were found in terms of wound infection, amputation, wound recurrence, or hospitalization. In patients with lower-extremity venous ulcers or pressure ulcers, the SOE was insufficient to estimate an effect on critical outcomes, such as complete wound closure or time to complete wound closure. There was no statistically significant difference in adverse events. CONCLUSION Autologous PRP may increase complete wound closure, shorten healing time, and reduce wound size in individuals with lower-extremity diabetic ulcers. The evidence is insufficient to estimate an effect on wound healing in individuals with lower-extremity venous ulcers or pressure ulcers. TRIAL REGISTRATION PROSPERO Identifier: CRD42020172817.

Abstract
BACKGROUND Several diagnostic tests and treatment options for patients with lower extremity varicose veins have existed for decades. The purpose of this systematic review was to summarize the latest evidence to support the forthcoming updates of the clinical practice guidelines on the management of varicose veins for the Society for Vascular Surgery (SVS), the American Venous Forum (AVF) and the American Vein and Lymphatic Society. METHODS We searched multiple databases for studies that addressed four clinical questions identified by the AVF and the SVS guideline committee about evaluating and treating patients with varicose veins. Studies were selected and appraised by pairs of independent reviewers. A meta-analysis was conducted when feasible. RESULTS We included 73 original studies (45 were randomized controlled trials) and 1 systematic review from 12,915 candidate references. Moderate certainty of evidence supported the usefulness of duplex ultrasound (DUS) examination as the gold standard test for diagnosing saphenous vein incompetence in patients with varicose veins and chronic venous insufficiency (clinical, etiological, anatomic, pathophysiological classification [CEAP] class C2-C6). High ligation and stripping (HL/S) was associated with higher anatomic closure rates at 30 days and 5 years when compared with radiofrequency ablation and ultrasound-guided foam sclerotherapy (UGFS) (moderate certainty), while no significant difference was seen when compared with endovenous laser ablation (EVLA) at 5 years. UGFS was associated with an increased risk of recurrence compared with HL/S. EVLA was associated with lower anatomic closure rates at 30 days than cyanoacrylate closure (CAC) and higher rates at one and 5 years when compared with UGFS. Thermal interventions were associated with lower generic quality of life scores and an increased risk of adverse events when compared with CAC or n-butyl cyanoacrylate (low certainty). Thermal interventions were associated with a lower risk of recurrent incompetence when compared with UGFS and an increased risk of recurrent incompetence than CAC. The evidence for great saphenous vein ablation alone to manage perforator disease was inconclusive. CONCLUSIONS The current systematic review summarizes the evidence to develop and support forthcoming updated SVS/AVF/American Vein and Lymphatic Society clinical practice guideline recommendations. The evidence supports duplex scanning for evaluating patients with varicose veins and confirms that HL/S resulted in similar long-term saphenous vein closure rates as EVLA and in better rates than radiofrequency ablation and UGFS. Thermal interventions were associated with inferior generic quality of life scores than nonthermal interventions, but had a lower risk of recurrent incompetence than UGFS. The recommendations in the guidelines should consider this information as well as other factors such as patients' values and preferences, anatomic considerations of individual patients, and surgical expertise.

Abstract
Economic valuation of ecosystem services is a new concept in forest management. Economic valuation provides basis for payment for ecosystem services (PES). Therefore, objective of this study was to evaluate eco-tourism and carbon stock services of the Maindam valley, District Swat, Pakistan. For the carbon stock calculation, a sample size of 155 plots of 0.1 hectare (Ha) was taken using preliminary survey at 95% confidence interval and 10% allowable error. The data for tourism services was collected from owners of all the hotels, 100 tourists and key informants of the area at 10% sampling intensity on pretested questionnaire for twenty years period (1997-2017). Results showed that Miandam valley has carbon stock worth US$ 16,306,000 while the value of eco-tourism was US$ 1,578,458 on annual basis. The results also showed that trend of tourism has drastically declined after the 9/11 incident for foreigners and locals and the situation was further deteriorated during the era of Talibanization or militancy from 2008-2011. This study recommends implementation of PES strategy at the rate of 5%, thus a total of US$ 78,922 can be earned from eco-tourism and carbon crediting in the study area annually, which could play important role in sustainable forest management.

Abstract
The present study was conducted for the taxonomic, morphometric and limnological assessment of the commercially important ichthyofauna of Sakhakot Stream, Malakand, Pakistan. The study area was divided into three sites along the water course namely Dargai Stream, Sakhakot Stream and Shergarh Stream. Fish samples were collected randomly during January to August 2017 with the help of fish gears. A taxonomic key was designed for the collected fish specimens. Ten fish species were identified belonging to 3 orders and 4 families. Family Cyprinidae was the dominant family with seven representative species while families Siluridae, Nemacheilidae and Mastacembelidae were represented by one species each. Lower mean total length and standard length was recorded in Puntius conchonius (Hamilton, 1822) as 9.2 ± 0.6 cm and 7.3 ± 0.6 cm respectively, while highest mean total length and standard length was recorded in Mastacembelus armatus (Lacepede, 1800) as 28.1 ± 1.7 cm and 15.9 ± 2.4 cm respectively. Mean pH of the water ranged from 6.1 at Shergarh Stream in August to 8.7 at Sakhakot Stream in January. Average temperature range was recorded from 10.9 °C in January at Dargai Stream to 18.7 °C in August at Shergarh Stream. No statistically significant difference was found for temperature (p = 0.96) and pH (p = 0.14) in the three water streams. The present study will provide a baseline for the rearing and enhancement of wild stock of the commercially important ichthyofauna in the field of aquaculture and fisheries.

Abstract
BACKGROUND To support the development of guidelines on the management of carotid disease, a writing committee from the Society for Vascular Surgery has commissioned this systematic review. METHODS We searched multiple data bases for studies addressing 5 questions: medical management vs. carotid revascularization (CEA) in asymptomatic patients, CEA vs. CAS in symptomatic low surgical risk patients, the optimal timing of revascularization after acute stroke, screening high risk patients for carotid disease, and the optimal sequence of interventions in patients with combined coronary and carotid disease. Studies were selected and appraised by pairs of independent reviewers. Meta-analyses were performed when feasible. RESULTS Medical management compared to carotid interventions in asymptomatic patients was associated with better early outcome during the first 30 days. However, CEA was associated with significantly lower long-term rate of stroke/death at 5 years. In symptomatic low risk surgical patients, CEA was associated with lower risk of stroke, but a significant increase in MI compared to CAS during the first 30 days. When the long-term outcome of transfemoral CAS vs. CEA in symptomatic patients were examined using pre-planned pooled analysis of individual patient data from four randomized trials, the risk of death or stroke within 120 days of the index procedure was 5.5% for CEA and 8.7% for CAS, which lends support that over the long-term, CEA has superior outcome than transfemoral CAS. When managing acute stroke, the comparison of CEA during the first 48 hours to that between day 2 and day14 did not reveal a statistically significant difference on outcomes during the first 30 days. Registry data show good results with CEA performed in the first week, but not within the first 48 hours. A single risk factor, aside from PAD, was associated with low carotid screening yield. Multiple risk factors greatly increase the yield of screening. Evidence on the timing of interventions in patients with combined carotid and coronary disease was sparse and imprecise. Patients without carotid symptoms, who had the carotid intervention first, compared to a combined carotid intervention and CABG, had better outcomes. CONCLUSIONS This updated evidence summary will support the SVS clinical practice guidelines for commonly raised clinical scenarios. CEA was superior to medical therapy in long-term prevention of stroke/death over medical therapy. CEA was also superior to transfemoral CAS in minimizing long-term stroke/death for symptomatic low risk surgical patients. CEA should optimally be performed between 2-14 days from the onset of acute stroke. Having multiple risk factors increases the value of carotid screening.

Abstract
We propose a novel method to exploit chirality of highly sensitive graphene plasmonic metasurfaces to characterize complex refractive indexes (RI) of viruses by detecting the polarization state of the reflected electric fields in the THz spectrum. A dispersive graphene metasurface is designed to produce chiral surface currents to couple linearly polarized incident fields to circularly polarized reflected fields. The metasurface sensing sensitivity is the result of surface plasmon currents that flow in a chiral fashion with strong intensity due to the underlying geometrical resonance. Consequently, unique polarization states are observed in the far-field with the ellipticity values that change rapidly with the analyte's RI. The determination of bimolecular RI is treated as an inverse problem in which the polarization states of the virus is compared with a pre-calculated calibration model that is obtained by full-wave electromagnetic simulations. We demonstrate the polarization selective sensing method by RI discrimination of three different types of Avian Influenza (AI) viruses including H1N1, H5N2, and H9N2 is possible. Since the proposed virus characterization method only requires determination of the polarization ellipses including its orientation at monochromatic frequency, the required instrumentation is simpler compared to traditional spectroscopic methods which need a broadband frequency scan.
