Abstract
Background:
Pyrimidine derivative has evinced its biological importance in targeting lung cancer by inhibiting neutrophil elastase.
Methods:
All THPM derivatives synthesized by the grindstone method at ambient temperature followed by molecular docking study for efficient binding interaction of THPM compounds by targeting human neutrophil elastase (HNE) (PDB ID: 5A0A) and In-silico ADMET study using PkCSM. Moreover, All synthesized compounds were characterized by spectroscopy techniques and screened for anti-cancer activity using in vitro HNE assay kit.
Results:
We reported a one-pot solvent-free mechanochemical approach for synthesizing tetrahydropyrimidine (THPM) derivatives from various aromatic aldehydes, ethyl cyanoacetate, and urea, followed by in silico study and evaluation against human neutrophil elastase (HNE) for treatment of lung cancer. We calibrated the best molecules that bind to specific targets more efficiently using a molecular docking approach and provided the desired efficacy. In-silico ADMET studies revealed that all best-scored compounds had drug-like characteristics for potential use as human neutrophil elastase inhibitors (HNE) in lung cancer treatment. Additionally, the in vitro studies revealed that compounds 1, 2, and 8 show potent HNE inhibitory activity for lung cancer treatment.
Conclusion:
In a nutshell, the tetrahydropyrimidine (THPM) scaffold and its derivatives may serve as potential HNE inhibitors for the development of a promising anti-cancer agent.

Abstract
Introduction Intimate partner Violence (IPV) against women includes all actions that violate one’s sense of self, physical body and sense of trust and involves episodes of violence of physical, psychological (emotional), or sexual nature, perpetrated by a current or former intimate partner. Objectives We estimated the prevalence of and risk factors for intimate partner violence (IPV) in the Himalayan mountain villages of Gilgit Baltistan in Pakistan. Methods We employed a cross-sectional study to randomly select ever married women (n=789) aged 18-49, in Pakistan. We used an adapted World Health Organization screening instrument to assess women’s experience of IPV in the previous 12 months. We used an indigenous validated instrument assess self-reported symptoms of major depression according to the DSM IV. Multivariable logistic regression analysis was used to identify significant predictors of IPV using adjusted odds ratio (AOR) with 95% confidence intervals (CI). Results The overall prevalence of IPV was 22.8% (95% CI: 20.0-25.9). Women exposed to IPV were less likely to have husbands educated at a college or a higher (AOR: 0.40; 95%CI: 0.22-0.70), household income in the middle or the highest tertile (AOR: 0.44; 95%CI: 0.29-0.68), and were more likely to have poor or very poor relationship with their mother in law (AOR=2.85; 95% CI: 1.90-4.28), to have a poor quality of health (AOR= 2.74; 95% CI: 1.92-3.92) poor quality of life (AOR= 3.54; 95%CI: 1.90-6.58), and higher odds of experiencing depressive symptoms (AOR=1.97; 95%CI:1.39-2.77). Conclusions IPV is a substantial public health burden in Himalayan mountain villages and merits serious attention. Disclosure No significant relationships.

Abstract
BackgroundAzathioprine (AZA) is a thiopurine immunosuppressant medication used to treat a variety of immune-mediated diseases. Unfortunately, its use is limited by adverse effects. Pancreatitis, a potentially severe, life-threatening side effect is independent of dose and necessitates AZA discontinuation given the high risk of recurrent pancreatitis with continued use or re-challenge. The mechanisms driving pancreatitis are unclear. While classic thiopurine-induced acute pancreatitis (TIAP) has been associated with HLA haplotypes, most patients taking AZA and presenting with pancreatitis do not fulfill the stringent criteria for TIAP.ObjectivesTo identify genetic risk factors for pancreatitis in patients taking azathioprine for immune-mediated conditions.MethodsUsing a biobank linked to electronic health records (EHR) from a tertiary center, we identified new users of AZA. Patients were excluded if the primary indication for AZA was organ transplant or if there was a history of pancreatitis prior to AZA use. The analysis was restricted to patients with EHR-reported race as White due to insufficient case counts for the non-White group. We then identified patients with amylase or lipase values that exceeded twice the upper limit of normal (“>2x ULN”) or with ICD-9/ICD-10 codes for acute pancreatitis. Each record was manually reviewed to confirm the timing of AZA use in relation to laboratory derangements or ICD coding, as well as to further classify patients into three increasingly strict, but not exclusive categories: 1) pancreatic injury (amylase or lipase >2x ULN); 2) acute pancreatitis1, or 3) TIAP2. We completed genotyping with Illumina Infinium Expanded Multi-Ethnic Genotyping Array plus custom content data, employed Michigan Imputation servers for genetic imputation, and used PrediXcan (GTEx v8) to impute gene expression. We then conducted genome-wide association and transcriptome-wide association studies (GWAS, TWAS). Acknowledging the relatively small overall cohort, and possible imbalance of cases vs controls, we used the Firth logistic regression method, which is a penalized likelihood-based method.ResultsWe studied 2127 AZA users (35.4% male; mean 44.5+/-17.2 years). The median AZA dose was 100mg/day (IQR: 50-125mg/day). Rheumatologic conditions (56.9%) and inflammatory bowel disease (40.4%) comprised the most common primary indications for AZA. Pancreatic injury, pancreatitis, and TIAP were diagnosed in 42 (2.0%), 16 (0.8%), and 9 (0.4%) patients, respectively. GWAS identified several significantly associated genes, many with overlapping TWAS findings in the pancreas and liver (Figure 1). From these, the two protein-encoding genes Fms Related Receptor Tyrosine Kinase-1 (FLT1) and Ephrin type-B receptor-2 (EPHB2) overlapped in two or more pancreatitis phenotypes in the TWAS and GWAS, respectively. EPHB2 was associated with a 8.6-fold (P=1.84 x 10-8) and a 31.4-fold (P=2.87x 10-8) higher likelihood of pancreatic injury and TIAP, respectively.Figure 1.ConclusionFLT1—a gene that encodes a receptor tyrosine kinase and is a member of the vascular endothelial growth factor receptor (VEGFR) family—and EPHB2—a gene that encodes a member of the Eph receptor family, which is the largest subgroup of the receptor tyrosine kinase family—are novel genetic markers associated with pancreatitis in patients taking AZA. VEGF can potentiate inflammation and the pancreas microenvironment is known to promote VEGF expression, which has been linked to pancreatic cancer development; anti-VEGF treatments have been investigated both for mitigating inflammation and also anti-pancreatic cancer treatment. Future studies validating our findings in AZA-induced pancreatitis are warranted.References[1]Crockett et al. Gastroenterology (2018). 154(4):1096-1101.[2]Heap et al.

Abstract
BackgroundSystemic sclerosis (SSc) is a rare autoimmune disease characterized by progressive microvascular damage, collagen deposition and subsequent fibrosis of the skin and internal organs which contributes to substantial morbidity and premature death.1-2ObjectivesThe objective was to evaluate the disease burden of SSc patients prior to their SSc diagnosis.MethodsPatients with SSc were identified in a claims dataset (IBM MarketScan Commercial Database, 2015-2019) using ICD 10 diagnosis codes for SSc. Eligible subjects were required to have > 1 inpatient or >2 outpatient/office claims with a scleroderma diagnosis code on separate days and > 24 months of continuous health plan enrollment without a SSc diagnosis before the first SSc claim (‘index date’) and > 12 months of enrollment after the index date. Overall comorbid disease burden was assessed via the Charlson Comorbidity Index (CCI) 13-24 and 12 months before and 12 months after index date. The prevalence of SSc-related complications for atherosclerosis, pulmonary arterial hypertension (PAH), pulmonary fibrosis (PF), Raynaud’s Phenomenon (RP), and gastrointestinal (GI) complications (e.g., GERD, dysphagia, etc.) were identified using ICD codes and reported as percentages for the aforementioned time intervals relative to patients’ index dates.Results902 eligible SSc patients were identified for analysis. The mean age at index SSc diagnosis was 54.3 years and 84.7% of patients were female. Mean CCI scores 13-24 months before, 12 months before, and 12 months after index SSc diagnosis were 0.84, 1.13 and 1.30, respectively. From the time points 13-24 months before, 12 months before, and 12 months after index SSc diagnosis, increasing rates were also observed of atherosclerosis, PAH, PF, RP, and GI complications (Table 1).Table 1.Charlson Comorbidity Index (CCI) and systemic sclerosis-related complications by time-intervalClinical characteristic13-24 months before Index12 months before Index12 months after IndexMean CCI (std dev)0.84 (1.58)1.13 (1.71)1.30 (1.75)Systemic sclerosis-related complicationsAtherosclerosis7%9%14%Pulmonary arterial hypertension (PAH)1%4%12%Pulmonary fibrosis (PF)5%8%16%Raynaud’s Phenomenon (RP)13%29%43%GI complications23%32%46%ConclusionResults from this analysis suggests that SSc-related sequalae are present at least two years prior to SSc diagnosis and rates of these complications increased markedly over time. Patients’ overall comorbid disease burden also worsened substantially over this period, likely because of these complications. The internal organ involvement is likely under reported due to requirements to link each diagnosis with an ICD-10 code. These data indicate the significant burden of SSc, prior to and after diagnosis, highlighting the need for awareness, prompt diagnosis, and effective therapies for SSc and its related complications.References[1]Cutolo M, et al.

Abstract
Umbilical hernia is one of the most common problems in young calves. This problem occurs in dairy sector as well as in the local farmers. Present study was conducted to compare outcomes of four different techniques of herniorrhaphy. Twenty four young calves (n=24) were divided in 4 groups (A, B, C, and D) which underwent four different surgical techniques. Group A underwent vicryl plus suture material and pants-over-west technique, Group B underwent mesh application with Dexon suture material by using simple interrupted suture pattern, Group C underwent closed method with Nylon No. 3 suture material by using vertical mattress suture pattern and Group D underwent clamp application method with Silk No. 2 suture material by using simple interrupted suture pattern. The result showed that mesh application method was comparatively better with respect to feed intake, body weight gain and healing time. There was no reoccurrence with non-significant hematological changes (p≤0.05). It is concluded that mesh application method is safer than other three techniques and there are no systemic effects of this surgical intervention on calves' health.

Abstract
COVID-19 pandemic has significantly affected the tourism and hospitality sectors across the globe. Due to the increase in the number of COVID positive cases, governments of countries have imposed strict lockdown globally as a precautionary measure to control the spread of the coronavirus, which has led to restrictions on travel and mobility of individuals from one place to the other. One of the countries that have been severely affected due to the lockdown is the economy of Nepal. Being a tourist-friendly nation, every year, Nepal’s tourism and hospitality sector contributes significantly to its GDP. With a restriction on travel and cancellation of bookings, one of the most important departments under this sector, the hotel industry, is currently struggling to survive due to loss of revenue. The present study tries to understand the challenges and strategies planned by the hotel industry stakeholders in Nepal. A primary survey conducted with hoteliers from 10 hotels reveals major concerns about maintaining a steady financial performance and expectations for government aid to help this sector come back to normalcy.

Type of funding sources: None.
Background/Introduction: Cryoballoon ablation (CBA) is often associated with shorter procedure times along with tradeoffs such as increased fluoroscopy use compared to radiofrequency (RF) ablation of atrial fibrillation (AF), however the impact of mapping technology on these characteristics is not fully understood.
Purpose
To assess the effect of mapping technology on trends in fluoroscopy use and procedure times in AF pulmonary vein isolation (PVI) procedures with an RF or CBA catheter.
Methods
Acute procedure data from 210 de novo AF cases using a 3D mapping system was prospectively collected from 48 centers in eight countries. Choice of technology was left to physician discretion; a PVI only ablation strategy was utilized in all cases. Procedure data such as total procedure and fluoroscopy times from cases using either an RF or CBA catheter with either a grid-style mapping catheter (HD Grid) or circular mapping catheter (CMC) were compared.
Results
Of the 210 cases, RF ablation was used in 103 (49%), and CBA used in 107 (51%). In RF cases, a relatively even split between CMC and HD Grid use was observed (n=46, 45% vs. n=57, 55%), while a CMC was used in 100% of CBA cases (Figure 1). Across all cases, fluoroscopy and procedure times were significantly shorter when HD Grid was used (7.4±26.7 minutes; 108.2±46.3 minutes) compared to a CMC (20.4±17.6 minutes; 133.7±62.7) (p<0.001; p=0.003). A similar trend was also observed in RF cases using HD Grid (7.4±26.7 minutes; 108.2±46.3 minutes) compared to a CMC (17.9±12.3 minutes; 175.1±50.5) (p=0.01; p<0.001). Fluoroscopy times in RF cases with HD Grid (7.4±26.7 minutes) were significantly shorter compared to CBA cases with a CMC (21.5±19.4 minutes) (p<0.001), while procedure times were similar (108.2±46.3 minutes; 116.0±59.2 minutes, p=0.20).
Conclusion(s)
Use of HD Grid resulted in significantly shorter procedure and fluoroscopy times compared to a CMC across all cases, including those using RF ablation. Fluoroscopy times were also significantly shorter in RF cases using HD Grid compared to CBA cases using a CMC, with similar procedure times. These observations suggest that use of HD Grid may better enable safer and more efficient PVI, specifically when employing RF ablation, in addition to safer and equally efficient RF PVI compared to CBA with a CMC. Further study in in a larger, randomized cohort may be necessary.

Background/Introduction
Choice in mapping technology may play a critical role in reducing fluoroscopy and procedure times during atrial fibrillation (AF) ablation, however this relationship is not well studied.
Purpose
To assess the impact of mapping technology on trends in fluoroscopy use and procedure times in AF ablation procedures.
Methods
Acute procedure data from 525 AF cases was prospectively collected from 68 centers in nine countries. Choice of technology and ablation strategy, including PVI and substrate modification, were left to physician discretion. Procedure data such as total procedure and fluoroscopy times from cases using a grid-style mapping catheter (HD Grid) were compared to those using a circular mapping catheter (CMC).
Results
Of the 525 cases, HD Grid was used in 230 (44%), and CMC was used in 295 (56%). HD Grid was routinely used for both de novo and redo procedures while CMC was used predominantly for de novo procedures (Table 1). Similar procedure times were noted in redo PAF and redo PersAF procedures, while significantly shorter procedure times were observed for the HD Grid group in both de novo PAF and PersAF (113.9±48.8 vs. 125.9±56.3 minutes, p=0.04; and 142.8±53.2 vs. 169.8±52.2 minutes, p=0.001).
Overall fluoroscopy times were significantly shorter using HD Grid compared to a CMC (9.0±19.6 minutes vs. 19.8±16.4 minutes, p<0.001), including significantly shorter fluoroscopy times in de novo PAF, de novo PersAF, and redo PAF (Table 1). There were 155 cases completed without fluoroscopy use; zero fluoroscopy cases accounted for 50% (114/230) and 14% (41/295) of total cases completed with HD Grid and a CMC, respectively (p<0.001).
Conclusion(s)
Use of HD Grid was observed in a significantly higher portion of zero fluoroscopy cases and resulted in significantly shorter procedure and fluoroscopy times in both de novo PAF and de novo PersAF and significantly shorter fluoroscopy times in redo PAF. These observations suggest that use of HD Grid may better enable faster and safer procedures in these specific AF types compared to CMCs, although further analysis in a larger, randomized cohort may be warranted.

Abstract
A 68-year-old female patient who was treated with anti-viral, steroids and biologics for coronavirus disease- 19 (COVID- 19) infection presented to our facility following right abdominal and flank pain since a week. Initially attributed to pancreatitis and right sided pyelonephritis, it was diagnosed as mucormycosis on KOH mount following CT-guided renal biopsy. She underwent right total nephrectomy and Whipple's surgery followed by Isavuconazole and liposomal Amphotericin B. This is a rare presentation of renal and gastrointestinal mucormycosis in a patient without diabetes mellitus following COVID- 19 infection. High suspicion and early diagnosis help in timely treatment of this life-threatening infection.

Abstract
Cyanotoxins are among common contaminants that can impair human, animal, and environmental health. Cylindrospermopsin (CYN) is an abundant form of cyanotoxins elevated following algal bloom in the water worldwide. Previous studies have described CYN effects on several organs in mammals. However, little is known about its toxicity mechanisms in other vertebrates. This study aims to characterize the developmental effects of CYN using zebrafish larvae as an aquatic model organism. A wide range of CYN concentrations (0-2000 μg/L) was tested using a morphometric approach for survival, hatching, various growth and developmental abnormalities. We also investigated the expression of genes related to oxidative stress, osmoregulation, and thyroid function. Exposure to CYN resulted in decreased growth, increased developmental abnormalities such as pericardial and yolk sac edema as well as swim bladder absence. In addition, CYN increased tr1a, and decreased dio1 and dio3 transcript levels which are involved in thyroid-mediated function. It also increased transcript levels related to oxidative stress, including hsp70, ahr1a, cyp1a, gpx and cat. Lastly, CYN exposure increased aqp3a and decreased dab2, which are involved in osmoregulation with a threshold of 10 μg/L. The present study demonstrates multiple effects of exposure to environmentally relevant CYN concentrations in zebrafish embryos.

Abstract
Rare diseases are life-threatening or chronically debilitating low-prevalent disorders caused by pathogenic mutations or particular environmental insults. Due to their high complexity and low frequency, important gaps still exist in their prevention, diagnosis, and treatment. Since new drug discovery is a very costly and time-consuming process, leading pharmaceutical companies show relatively low interest in orphan drug research and development due to the high cost of investments compared to the low market return of the product. Drug repurposing–based approaches appear then as cost- and time-saving strategies for the development of therapeutic opportunities for rare diseases. In this article, we discuss the scientific, regulatory, and economic aspects of the development of repurposed drugs for the treatment of rare neurodegenerative disorders with a particular focus on Huntington’s disease, Friedreich’s ataxia, Wolfram syndrome, and amyotrophic lateral sclerosis. The role of academia, pharmaceutical companies, patient associations, and foundations in the identification of candidate compounds and their preclinical and clinical evaluation will also be discussed.

Abstract
OBJECTIVE The rational use of medicines as per the World Health Organization (WHO) should be practiced globally. However, data regarding the completeness of the prescriptions and their rational use is lacking from developing countries like India. Thus, the aim of this study was to assess the prescribing patterns of drugs and completeness of prescriptions as per WHO core drug use and complementary indicators to provide real-life examples for the Indian Council of Medical Research (ICMR) online prescribing skill course for medical graduates. METHODS Prescriptions of the patients, fulfilling inclusion criteria, attending Outpatient Departments of various specialties of tertiary care hospitals, were collected by thirteen ICMR Rational use of medicines centers located in tertiary care hospitals, throughout India. Prescriptions were evaluated for rational use of medicines according to the WHO guidelines and for appropriateness as per standard treatment guidelines using a common protocol approved by local Ethics committees. RESULTS Among 4838 prescriptions, an average of about three drugs (3.34) was prescribed to the patients per prescription. Polypharmacy was noted in 83.05% of prescriptions. Generic drugs were prescribed in 47.58% of the prescriptions. Further, antimicrobials were prescribed in 17.63% of the prescriptions and only 4.98% of prescriptions were with injectables. During the prescription evaluation, 38.65% of the prescriptions were incomplete due to multiple omissions such as dose, duration, and formulation. CONCLUSION Most of the parameters in the present study were out of the range of WHO-recommended prescribing indicators. Therefore, effective intervention program, like training, for the promotion of rational drug use practice was recommended to improve the prescribing pattern of drugs and the quality of prescriptions all over the country.

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.
