Abstract
Aim To examine unexplored knowledge of cardiovascular highrisk medications and perception thereof among practising nurses and students in the Kingdom of Saudi Arabia (KSA). Methods The multicentre cross-sectional quantitative study used an online survey dichotomised into a knowledge test (true/false and multiple choice questions) and a perception assessment (closed-ended questions). Four hundred and eighteen nurses participated in the study. Results In the knowledge test, 19 (4.5%) participants scored high (≥71%), while 83 (19.8%) and 316 (75.5%) demonstrated moderate (score ≥51-70%) and poor performance (score ≤50%), respectively. In a comparative analysis, the knowledge level of staff nurses was significantly higher than the students but not the other nurses' cohort. Nurses' specialty and region of KSA were strongly associated with the knowledge level. Emergency room nurses and those belonging to the eastern region of KSA exhibited higher knowledge levels than other subgroups. A vast majority of nurses, 128 (30.6 %), rated their knowledge of medicines as somewhat sufficient, while quoting insufficient knowledge 226 (54.1%) as the major cause of medication errors. Three hundred and sixteen (75%) nurses expressed interest in undergoing specialised training in high-alert medication-based therapy preferably in a classroom setting by 279 (66.7%). Conclusion This study revealed a marked knowledge deficit in high-risk cardiovascular drugs among nurses. The pharmacological curriculum in nursing schools should be tailored to be clinically oriented and reinforced with problem-based learning. Continued pharmacology education focusing on high-risk drugs should be implemented among nurses to safeguard patient lives by mitigating the risks of medication error.

Abstract
Background COVID-19 pandemic and its related personal protective equipment have impacted all aspects of dental education. The qualitative study assesses the impact of COVID-19-related changes and their effects on students' clinical learning from student and faculty perspectives. Methods This qualitative study involved third- and fourth-year predoctoral dental students and full-time dental clinical faculty. A semistructured interview guide was used. The interview guide consisted of seven open-ended questions about the impact of the new COVID-19-related infection control procedures on students' learning experience in the dental clinic. Interviews were recorded, transcribed verbatim, and analyzed using a basic interpretative approach by two independent researchers. Emerged themes were identified. Results Twelve faculty members and 21 students participated in six focus groups. Three major themes emerged from the analysis: learning challenges, learning opportunities, and long-term impact. Students identified four categories of learning challenges: communication, visualization, clinical exposure, and heat. Five learning challenges identified by faculty were: faculty burnout, service delivery challenges, material wastage, teaching difficulties, and lack of comprehensive care. The five learning opportunities students identified were autonomy, preparedness, efficiency, safety, and personalized feedback. Learning opportunities identified by faculty were time management, autonomy, and preparedness. Three categories of long-term impact on students identified were future opportunities, adaptation, and postgraduation plans. Faculty identified apathy, career re-evaluation, and adaption as the long-term impact of COVID-19-related changes. Conclusion Although the new COVID-19-related infection control procedures and regulations in the dental school clinical setting come with learning challenges, students and faculty also saw learning opportunities through increased autonomy, preparedness, and efficiency. The impact of COVID-19 extends beyond the current learning experiences as it may modify students' long-term plans.

Abstract
Abstract Transplanting time and genotype contribute to improving crop yield and quality of eggplant (Solanum melongena L.). A field experiment was conducted to investigate the impact of foliar applied of triacontanol (TRIA) and eggplant genotypes 25919, Nirala, 28389 and Pak-10927,transplanted on 1 March,15 March, and 1 April on exposure to high air temperature conditions. The experiment was performed according to Randomized Complete Block Design and the data was analyzed by using Tuckey,s test . The TRIA was applied at 10µM at flowering stage; distilled water was used as the control. Rate of photosynthesis and transpiration, stomatal conductance, water use efficiency, and effects on antioxidative enzymes (superoxide dismutase, catalase and peroxidase) were evaluated. The 10µM TRIA increased photosynthesis rate and water use efficiency and yield was improved in all genotypes transplanted at the different dates. Foliar application of 10µM TRIA increased antioxidative enzyme activities (SOD, POD & CAT) and improved physiological as well as biochemical attributes of eggplant genotypes exposed to high heat conditions. Highest activity of dismutase enzyme 5.41mg/1g FW was recorded in Nirala genotype in second transplantation. Whereas, lowest was noted in PAK-10927 (2.30mg/g FW). Maximum fruit yield was found in accession 25919 (1.725kg per plant) at 1st transplantation with Triacontanol, whereas accession PAK-10927 gave the lowest yield (0.285 kg per plant) at control treatment on 3rd transplantation. Genotype, transplanting date and application of TRIA improved growth, yield and quality attributes under of heat stress in eggplant.

Abstract
Background At Groote Schuur Hospital (GSH), the neurosurgical intensive care unit (NsICU) is a 6-bed unit headed by a specialist neurosurgeon with extensive experience in neurocritical care, working in close collaboration with intensivists from the Division of Critical Care. There is currently no detailed analysis of the demographics, diagnosis and management of patients admitted to the NsICU at GSH. Objectives To provide a detailed descriptive analysis of the demographics, diagnosis and management of patients admitted to the NsICU at GSH from 1 January 2020 to 31 December 2021. Methods A retrospective descriptive analysis was done of patients who received treatment in the NsICU from 1 January 2020 to 31 December 2021. Results A total of 685 patients were admitted to the unit over a 2-year period, with a male preponderance (68.2%). The average age was 42.5 (standard deviation (SD) 17.2) years. The most common neurosurgical diagnoses were traumatic brain injuries (39.6%), brain tumours (22.6%) and aneurysmal subarachnoid haemorrhages (9.9%). Emergency admissions comprised 76.6% of the total and 86.7% of patients were admitted postoperatively. Three hundred and seventy-two patients (54.3%) required mechanical ventilation, 132 (19.3%) required both an intracranial pressure (ICP) monitor and brain tissue oxygenation monitor, 86 (12.5%) needed placement of an external ventricular drain, 50 (7.3%) needed placement of a tracheostomy tube and 16 (2.3%) needed placement of an ICP monitor only. The average duration of stay was 5.5 (1.3) days and NsICU mortality over 2 years was 11.1%. Conclusion The NsICU at GSH manages predominantly male trauma patients and a significant number of admitted patients require specialised invasive intracranial monitoring. Contribution of the study This is the first in-depth analysis of patients managed in a dedicated neurosurgical intensive care unit in South Africa. The work defines the patient population, neurosurgical pathologies and service level requirements that would likely be encountered by teams building a similar service.

Abstract
Objectives: The study aimed to determine dietary Intake patterns in women with GDM and Non-GDM, a comparative study in a tertiary care hospital, Pakistan. Methods: This comparative cross sectional study was conducted through questionnaire spread over a period of six months of pregnant women visiting to Abbasi Shaheed Hospital for ante-natal visit having 24 to 28 weeks of gestation. With the written consent of the participants dietary intake patterns were assessed in GDM & Non-GDM subjects by a three day 24 hours’ recalls and food frequency questionnaire. A 24-hour dietary recall chart is a dietary assessment tool in which participants were asked to recall all food and drink they have consumed in the last 24 hours. The FFQ (food frequency questionnaire) provide a list of foods and participants were asked how often they eat each item on the list. This FFQ has 70 food items. The food frequency was reported as never, per year, per month, once a week, once and a day. The reported intake of food was converted into nutrients intake (carbohydrate, protein, fat) which was calculated by reported intake frequency of each food multiplied by reported portion size and its respective nutrient composition, summing over all foods by a trained Nutritionist. Results: A total of 75 participants with GDM, and 75 with Non-GDM were enrolled in this study over a period of six months. It was observed that dietary intake patterns have a significant association with GDM. Those who consume carbohydrate mainly containing diet have likely to have GDM. It has been seen that those who have family history of diabetes are more likely to have GDM. Family dietary patterns can affect risk of GDM. Our study has shown that timings of meals did not find have any significant association with GDM. Conclusion: Dietary patterns strongly influence the risk of GDM. The most contributing factors to risk of GDM are higher intake of carbohydrate rich diet and lesser consumption of fruits and vegetables.

Abstract
Objective
The objective of this study was to evaluate students’ perceptions of differences in learning from faculty of different gender.
Method
This cross-sectional study involved pre-doctoral dental students (years 2 to 4) who had a simulation and/or clinical experience working with dental faculty for at least one year. Students completed a self-administered questionnaire with three sections: demographic, difference between faculty related to their knowledge, skill, critical thinking, acceptance of cultural differences, and students’ preferences in working with faculty in specialty clinics.
Results
A total of 136 students completed the survey (75.4% response rate). Participants were 52.6% women, 62.2% self-identified as Caucasian/White. Students reported that female faculty are more understanding (p = 0.001) and accepting of cultural differences (p<0.001) compared to male faculty (p<0.05). Students reported perceiving female faculty more as being a role model than male faculty (p = 0.034). When comparing male and female students, male student’s perception of male faculty as a role model was significantly higher than female students (p<0.05). There was no significant difference in student’s perceptions between male and female faculty in their knowledge, skills, compassion, critical thinking, providing feedback, communication skills, and grading (p>0.05). Caucasian/White students perceived female faculty as more encouraging for discussions and male faculty as more rigid/inflexible (p<0.05).
Conclusions
Students perceived female faculty as more understanding and culturally competent compared to male faculty. There were no significant differences in student’s perceptions of male and female faculty in their knowledge, skills, compassion, critical thinking, feedback, communication skills, and grading. Students perceived female faculty as role models more than male faculty.

Abstract
PURPOSE To evaluate the whitening efficacy of charcoal powder compared to a whitening toothpaste and the surface loss using scanning electron microscopy (SEM) and confocal laser scanning microscope (CLSM). METHODS 60 human extracted teeth were randomly assigned to two groups: Treatment (T, charcoal group: Premium Nature) and Control (C, whitening toothpaste group: Colgate Optic White). Teeth in the treatment group were brushed with a charcoal paste. Teeth shade was evaluated before and after the intervention. Lightness was assessed using both VITA classical shade guide and VITA Easyshade V. Changes within and between the group were evaluated by the paired-sample t-test and independent sample t-test. Surface roughness (Ra) of samples was performed using SEM, and to assess surface loss a CLSM was used. RESULTS At baseline, there were no significant differences in teeth lightness, chroma, or hue between both the charcoal and the whitening toothpaste groups (P> 0.05). After 21 days of brushing, teeth brushed with the whitening toothpaste were significantly lighter (VITA Easyshade mean score: 78.34, SD: 8.397; VITA classical A1-D4 shade mean: 8.90, SD: 4.475) than the charcoal group (VITA Easyshade mean: 69.70, SD: 6.364; VITA classical A1-D4 shade mean: 11.77; SD: 3.421) (P< 0.001). In addition, there was a significant reduction in lightness (i.e., increase in darkness) within the charcoal group after the intervention (P< 0.001). There was no significant difference in chroma and hue between the charcoal and the whitening toothpaste groups (P> 0.05). There was no significant tooth loss nor roughness change (P= 0.867) for both groups when compared with natural tooth structure. Brushing teeth with the charcoal paste tested for 21 days had no effect on tooth lightness, chroma, or hue. Charcoal powder had no significant effect on tooth surface roughness. CLINICAL SIGNIFICANCE The Premium Nature charcoal toothpaste tested had no tooth whitening effect.

Abstract
L-Glutamic acid (Glu) is used as an effective bio-stimulant to reduce arsenic (As) stress in plants. The role of Glu was studied in the protection of photosynthesis and growth of rice (Oryza sativa L. Japonica Type Taipie-309) plants grown with 50 μM As stress by studying the oxidative stress, photosynthetic and growth characteristics. Among the Glu concentrations (0, 2.5, 5 and 10 μM), 10 μM Glu maximally enhanced photosynthesis and growth parameters with the least cellular oxidative stress level. The supplementation of 10 μM Glu resulted in the reduced effects of As stress on gas exchange parameters, PSII activity and growth attributes through enhancement of antioxidant and proline metabolism. The enzymes of nitrogen (N) assimilation, such as nitrate reductase, nitrite reductase, glutamine synthetase and glutamate synthase were increased with Glu treatment under As stress. The Glu-induced metabolite synthesis showed the role of various metabolites in As stress responses. The role of Glu as a signalling molecule in reducing the adverse effects of As through accelerating the antioxidant enzymes, PSII activity, proline metabolism and nitrogen assimilation has been discussed.

Abstract
This study aimed to determine the correlation between random urinary protein-to-creatinine ratio in single-voided urine samples and 24-h urinary protein excretion in pregnant women with preeclampsia. A cross-sectional study was conducted at the Department of Gynecology and Obstetrics, Abbasi Shaheed Hospital, Karachi, Pakistan, from July 2019 to June 2020. Fifty women with singleton pregnancy after 20 weeks of gestation with hypertension and 2+ proteinuria or more, according to a dipstick test, were included. Those with chronic hypertension; preexisting renal disease; gestational diabetes; eclampsia; hemolysis, elevated liver enzymes, a low platelet count syndrome; and coexisting urinary tract infections were excluded. Two random urine samples taken at 9:00 a.m. and 2:00 p.m. and 24-h urine samples were collected to evaluate the random urinary protein-to-creatinine and the 24-h protein excretion, respectively. The correlation coefficient (r) between them was calculated using Pearson's correlation test. The patients' mean age was 28.58 ± 5.09 years and their mean gestational age was 32.74 ± 4.44 weeks. Twenty-eight (56%) women were primigravidas, and 22 (44%) were multiparous. The average serum creatinine was 0.80 ± 0.16 mg/dL. The mean random urinary protein-to-creatinine ratio was 0.93 ± 0.7 mg/mg, and the mean 24-h urine was 481.08 ± 20.10 mL. A strong positive correlation was found between the protein-to-creatinine ratio and 24-h urinary protein excretion (r = 0.655; P = 0.01). We concluded that the protein-to-creatinine ratio in spot urine samples could be used as an alternative to in 24-h collection of urine to determine protein excretion in preeclamptic pregnant women.

Abstract
Measles, mumps, and rubella (MMR) are among the most important viral infectious diseases in Iran and neighboring countries. After using a trivalent vaccine for these three diseases for a long time, in recent years, these diseases have been significantly controlled in Iran. One of the important points of storing the vaccine is that the vaccine strains are highly temperature-sensitive viruses. Due to tropical climatic conditions in Iran, the cold chain may not be achievable during the storage and transmission of the MMR vaccine. Therefore, the efficacy of the vaccine may be affected. This study aimed to evaluate the MMR vaccine potency at different temperatures (stress tests) and frequent light exposures. All quality control tests in the form of stability studies were performed on the samples from three consecutive batches produced during a full-scale Razi production. The samples were stored at 2-8, 22-25, 35-37, and 42-45°C in specific time intervals, exposed to frequent light, and underwent freezing/thawing conditions. According to the results, the storage of the vaccine at high temperatures caused a decrease in potency and increased moisture content in the vaccine vials. The best temperature for maintenance and transportation of MMR is 2-8°C. The time and frequency of light exposure may affect the vaccine potency. Based on the sensitivity of the vaccine strains to environmental conditions, the development of plans for storage and transportation of vaccines in different situations and training the vaccine injection staff seem necessary.

Abstract
Abstract
Objectives
The prevalence of atrial fibrillation (AF) and atrial flutter (AFl) increases with age. Prior research suggests that underprescription of anticoagulants, such as warfarin, in older adults can lead to increased morbidity and mortality. We analyzed rates and patterns of warfarin prescription in older adults.
Methods
In this prospective observational study, we enrolled 2179 consecutive patients with admission diagnosis of AF or AFl. Those placed on a non-warfarin anticoagulation (189 patients) were excluded. Patients were then divided into “older cohort” (≥75 years of age) and “younger cohort” (<75 years of age). Within the older cohort, prescription patterns of warfarin were analyzed. Serial prospective follow-up was 3.1±2.06 years.
Results
Of the 1990 patients, 46.9% were ≥75 years older, of which 51.1% were prescribed warfarin. There was no difference between mean CHA2DS2-VASc score and warfarin prescription (OR=1.06 (95% CI 0.93–1.21), p=0.388) in the older cohort. After adjusting for hypertension, glomerular filtration rate, and Black race, appropriate warfarin prescription in older adults was independently associated with lower aspirin prescription rates (OR=0.57 (95% CI 0.43–0.75), p<0.001), lower body mass index (OR=1.03 (95% CI 1.01–10.6), p=0.018), and lower hemoglobin levels (OR=1.11 (95% CI 1.04–1.19), p=0.002).
Conclusions
In our study, adults 75 years and older with AF and AFl tended to have lower rates of warfarin prescription despite higher CHA2DS2-VASc score and higher risk of thromboembolic events. Anemia, lower weight, and aspirin use were characteristics associated with warfarin underprescription. These patterns can shed light on clinicians' perceived hesitancy to anticoagulate certain older adults.

Abstract
Abstract
Background
Statins are the cornerstone of primary and secondary prevention of atheroscleoric cardiovascular disease (ASCVD). Our previous retrospective analysis of 1042 consecutive patient encounters at a large urban academic institution found that one in five patients were not prescribed an appropriate statin therapy. These patients tended to be younger, of Black race, and met statin-eligibility solely via a 10-year ASCVD risk score ≥7.5%. Only one-third of patients had follow-up cholesterol levels ordered to monitor treatment efficacy.
Purpose
To improve adherence to cholesterol guidelines at our academic institution.
Methods
We implemented multiple interventions over a four-month period to support clinical decision making of guideline directed statin therapy: a) development of an online interactive tool, b) physician education on updated cholesterol guidelines and utilization of the tool, c) display of guideline summary in the workspace, and d) a documentation reminder in the electronic health record. We randomly selected encounter dates, from which 622 consecutive patient visits were analyzed. The primary outcome measures were: prescription rates of statins, documentation of a 10-year ASCVD risk score, and follow-up cholesterol levels ordered to monitor treatment efficacy.
Results
Out of the 622 patients, 232 met statin indication. In this post-intervention group, statin prescriptions rates improved when compared to the pre-intervention group (90.5% vs 82.3%, p=0.006). Among the patients who met statin indication solely via a 10-year ASCVD risk score ≥7.5%, there was an increase in documentation of the calculated 10-year ASCVD risk score (72.3% vs 57.8%; p=0.039) and in statin prescription rate (90.8% vs 67.6%; p<0.001). In addition, there was an increase in follow-up cholesterol levels ordered in all patients included in our study who met statin indication (64.1% vs 33.3%; p<0.001).
Conclusion
Our study showed higher rates of statin prescription, 10-year ASCVD risk score documentation, and treatment monitoring after multiple interventions, including an easily accessible online interactive tool, at a large urban academic institution.

Abstract
Short wavelength high-harmonic sources are undergoing intense development for applications in spectroscopy and microscopy. Despite recent progress in peak and average power, spatial control over coherent extreme ultraviolet (XUV) beams remains a formidable challenge due to the lack of suitable optical elements for beam shaping and control. Here we demonstrate a robust and precise approach that structures XUV high-order harmonics in space as they are emitted from a nanostructured MgO crystal. Our demonstration paves the way for bridging the numerous applications of shaped light beams from the visible to the short wavelengths, with potential uses for applications in microscopy and nanoscale machining.

Abstract
BACKGROUND In a time of crisis, such as the COVID-19 pandemic, digital social support can prove helpful in buffering the stress and anxiety especially for students whose lives were being affected both socially and academically. The present study aims to explore the emotional and informational social support available to students during the online transformation of their education. It further investigates factors affecting anxiety and stress among students. DESIGN AND METHODS An online survey was administered among 479 undergraduate students at a private university in Saudi Arabia from 2nd March till 17th June 2020. Descriptive analysis was used to report the findings of students' self-reported data. RESULTS The results revealed that more than 70% of the students reported that they were satisfied with the informational and emotional support available to them via digital platforms. However, they felt less connected with the teachers and academic administration. Feeling sick (46%), being locked down at homes and isolation (43%) were major causes of stress and anxiety. 71% of the students reported their ability to keep themselves busy, however, only 55% of students mentioned that they did not feel lonely while confined to their homes. In these circumstances, the continuation of studies via online platforms helped students reduce stress and anxiety (52%). CONCLUSIONS Although this online transformation was not planned, the university was able to provide adequate informational support to the students. However, students were dependent upon friends, family and relatives for emotional support. The results of the study point towards the need of training for teachers and academic administrative staff in order to better address students' needs for social support during the crisis. The results also contribute to the body of data reporting the various effects of the COVID-19 pandemic on students in a way to reach a sustainable framework for supporting students.

Abstract
Colon cancer is a life-threatening disease all over the world and is linked to constant oxidative stress and inflammation. Epigallocatechin gallate (EGCG), is a naturally occurring flavone possessing health benefiting pharmacological properties including antioxidant, anti-inflammatory and free radical scavenging properties. Our study investigates the role of EGCG on N,N'-dimethylhydrazine (DMH), a toxic environmental pollutant, induced colon toxicity. To investigate the effect of EGCG, Wistar rats were given EGCG for 7 days at the two doses of 10 and 20 mg/kg body weight and DMH was injected on the seventh day in all the group rats except the control. Our results indicate that DMH administration increased the oxidative stress (MDA) and depleted the glutathione and antioxidant enzyme activities (SOD, CAT, GR, GST and GPx) which was significantly ameliorated by EGCG treatment. Additionally DMH treatment upregulated inflammatory markers expression (NF-κB, COX-2 and IL-6) and enhanced mucosal damage in the colon. EGCG treatment significantly reduced inflammation and restored the normal histoarchitecture of the colon. We can conclude from the present study findings that EGCG protects the colon from DMH toxicity through its antioxidant and anti-inflammatory potential.

Abstract
BACKGROUND The aim of this study was to determine whether a text messaging intervention (supported by a smartphone application) would be effective in the promotion of sun-safe behaviours. Both excessive and insufficient exposure to ultra-violet (UV) radiation were considered. METHODS A randomized control crossover trial was conducted. 112 participants from nine sites in the United Kingdom contributed to the study. There were three intervention waves, two in winter (Vitamin D-focussed) and one in summer (UV exposure-focussed). Stages of Change, Standard Erythemal (UV) Dose and assayed blood samples (Vitamin D) were employed to evaluate the effectiveness throughout the 21-day data collection periods. RESULTS The intervention was effective in promoting positive progression in Stages of Change for Vitamin D; and this in turn was predictive of increased Vitamin D levels in participants. More limited positive findings were found with respect to UV exposure. Overall, for those in the Intervention, Vitamin D levels were significantly predicted to increase during both of the winter data collection waves. CONCLUSIONS Interventions of this type are recommended to promote healthy Vitamin-D levels in construction workers.

Abstract
Valeriana wallichii, a perennial herb belonging to family Valerianaceae, is an important medicinal herb of the Himalayan region. The incessant exploitation of nature for meeting the demands of the pharmaceutical industry has put unbearable pressure on its natural habitats. A study on its physiological, biochemical, growth and reproductive attributes was planned. Physiological study revealed that ex-situ (outside their natural habitat) populations faced severe stress as compared to in-situ (natural habitat) plants. The difference in the performance of these habitat plants was related to superoxide and H2O2 in the leaves. Photosynthetic attributes were increased in in-situ populations. Proline content and its biosynthetic enzymes ornithine aminotransferase, and pyrroline-5-carboxylate reductase showed an increase in ex-situ plants; proline oxidase decreased. Glucose-6-phosphate dehydrogenase, shikimic acid dehydrogenese, phenylalanine lyase, and flavonoids content showed an increment in ex-situ plants. Antioxidants enzyme superoxide dismutase, catalase, ascorbate peroxidase and reduced glutathione showed an increment in ex-situ conditions. Growth and reproductive attributes were more in ex-situ plants. The observations made are suggestive that a comprehensive conservation programme involving in-situ as well as ex-situ strategies will be effective for the conservation and long term survival of the species.

Abstract
Benign prostatic hyperplasia (BPH) is an important key health concern for aging men. Polyphenolic compounds have been found to possess important roles in the inhibition of numerous ailments that involve reactive oxygen species and inflammation. Diosmin is a citrus flavone that possesses antioxidant, anti-inflammatory, antiproliferative, and anticancer activities, so based on these properties of diosmin, we decided to evaluate its effect on testosterone propionate (TP)-induced BPH. A total of 30 Wistar rats were randomly assigned to five groups having six animals in each. This study was of 28 days in which TP (5 mg kg−1) was administered to induce BPH in the last 10 days of the study. It was found that diosmin at the doses of 20 and 40 mg kg−1significantly reduced malondialdehyde and xanthine oxidase formation in a dose-dependent manner; however, it replenished catalase, glutathione (GSH), and GSH-dependent enzymes, that is, glutathione peroxidase, glutathione reductase, and glutathione- S-transferase significantly against TP-induced BPH. Further, immunohistochemical study showed that diosmin alleviated inflammatory markers (nuclear factor kappa-light-chain-enhancer of activated B cells, cyclooxygenase-2, and interleukin-6). It was also found that diosmin downregulated the expression of androgen receptor and decreased the prostate-specific antigen concentration dose-dependently, significantly against TP-induced BPH. Diosmin also restored histoarchitecture of the prostate in a dose-dependent manner. Findings from the present study revealed the protective role of diosmin against TP-induced BPH in Wistar rats.

Abstract
Seed germination of Citrullus colocynthis, as in many other species of Cucurbitaceae, is inhibited by light, particularly at low temperatures. Germination response to light and temperature has been attributed to day length and temperature during seed maturation. This study assessed the effects of these factors on the germination response of C. colocynthis to temperature and light quality. Ripe fruits were collected from natural habitats during December and February and germinated at three temperatures (15/25, 20/30 and 25/35 °C) in five light treatments (dark, white light and Red:Far Red (R:FR) ratios of 0.30, 0.87 and 1.19). Additionally, unripe fruits were also collected from natural habitats and completed their maturation in growth chambers under different day lengths (6, 16 and 24 h of darkness) at 10/20 °C, and in darkness at both 10/20 °C and 25/35 °C. Mature seeds of the different treatments were germinated in the same five light treatments at 15/25 °C. Germination was significantly higher in the dark than that in any light treatment. Seeds matured at higher temperatures (i.e. seeds from the December collection and those matured at 25/35 °C) had significantly higher germination than those matured at lower temperatures (i.e. seeds from the February collection and those matured at 10/20 °C). Dark germination was significantly higher for the December collection than for the February collection. Seeds of the two collections germinated in the dark only at 15/25 °C. However, seeds matured in a growth chamber at 10/20 °C in darkness germinated at 15/25 °C in all light treatments, except for the R:FR ratio 0.30. Seeds of the different treatments failed to germinate in FR-rich light. This study demonstrates that both temperature and day length during seed maturation play significant roles in the germination response of C. colocynthis. Additionally, the dark requirement for germination is likely beneficial for species with the larger seeds, such as C. colocynthis, which produce bigger seedlings that are able to emerge from deep soils and are competitively superior under dense vegetation and resource-limited conditions.

Abstract
AIMS Core surgical training (CST) programmes in the UK have seen a significant reduction in competition ratios over the past five years. This study aimed to determine motivating factors and perceived barriers to pursuing a career in surgery amongst junior doctors in training and medical students attending an annual conference. METHODS A self-reported, electronic questionnaire was distributed to medical students, foundation year doctors, and doctors in postgraduate surgical training programmes (DIPST) who attended the Association of Surgeons in Training (ASiT) Conference in 2016. Respondents ranked factors attracting them to a career in surgery and factors that could improve perceptions of surgical careers. Chi-square test was used to test for differences between groups (a = 0.05, R Studio, V3.3.1). RESULTS Of 394 respondents (response rate = 50.9%), 44.9% were medical students or foundation doctors ('Pre-CST') and 55.1% were DIPST ('Peri/post-CST'). Practical application of skills (97.4%), enjoyment of the theatre environment (95.4%) and positive experiences in surgical firms (84.7%) were primary driving factors towards a surgical career. Availability of private practice (32.2%), and sustainability of consultant jobs (49.0%) had less influence. For 'Pre-CST' respondents, role models (82.8% pre-CST v 74.9% peri-post CST, p < 0.05) and defined career progression (67.2% pre-CST v 47.0% peri-post CST, p < 0.001) were particularly important. 91% of all respondents agreed that a better balance of training and service within worked hours would improve perceptions of surgery. CONCLUSION Addressing the motivating factors and perceived barriers to surgical careers will help bolster recruitment of the future surgical workforce.

Abstract
BACKGROUND Patient selection for critical care admission must balance patient safety with optimal resource allocation. This study aimed to determine the relationship between critical care admission, and postoperative mortality after abdominal surgery. METHODS This prespecified secondary analysis of a multicentre, prospective, observational study included consecutive patients enrolled in the DISCOVER study from UK and Republic of Ireland undergoing major gastrointestinal and liver surgery between October and December 2014. The primary outcome was 30-day mortality. Multivariate logistic regression was used to explore associations between critical care admission (planned and unplanned) and mortality, and inter-centre variation in critical care admission after emergency laparotomy. RESULTS Of 4529 patients included, 37.8% (n=1713) underwent planned critical care admissions from theatre. Some 3.1% (n=86/2816) admitted to ward-level care subsequently underwent unplanned critical care admission. Overall 30-day mortality was 2.9% (n=133/4519), and the risk-adjusted association between 30-day mortality and critical care admission was higher in unplanned [odds ratio (OR): 8.65, 95% confidence interval (CI): 3.51-19.97) than planned admissions (OR: 2.32, 95% CI: 1.43-3.85). Some 26.7% of patients (n=1210/4529) underwent emergency laparotomies. After adjustment, 49.3% (95% CI: 46.8-51.9%, P<0.001) were predicted to have planned critical care admissions, with 7% (n=10/145) of centres outside the 95% CI. CONCLUSIONS After risk adjustment, no 30-day survival benefit was identified for either planned or unplanned postoperative admissions to critical care within this cohort. This likely represents appropriate admission of the highest-risk patients. Planned admissions in selected, intermediate-risk patients may present a strategy to mitigate the risk of unplanned admission. Substantial inter-centre variation exists in planned critical care admissions after emergency laparotomies.

Abstract
Mushrooms can be used as nutraceutical or functional foods to maintain and promote good health. In the present study, wild Ganoderma lucidum and four commercial mushrooms, Pleurotus ostreatus, Volvariella volvacea, Hericium erinaceus and Lentinus edodes, collected from Pakistan were screened for phenolics, tocopherols and fatty acid contents. High performance liquid chromatography analysis of phenolic acids showed that chlorogenic acid, ferulic acid, gallic acid, p-Coumaric and caffeic acids were observed in selected mushrooms. H. erinaceus contained high amounts of chlorogenic acid (11.49±0.1 µ/g of dry weight) and ferulic acid (7.84±0.7 µg/g of dry weight). γ-tocopherol and lutein were present in all studied mushrooms. Lutein contents were higher in H. erinaceus (2.42±0.087 µg/g of DW) followed by V. volvacea> P. ostreatus> L. edodes. γ-tocopherol was observed in the range of 74.25±3.01 to 29.65±1.2 µg/g of dry weight. GC/MS analysis of fatty acids showed that linoleic acid (18:2n6c), oleic acid (18:1n9c), palmitic acid (C16:0), stearic acid (C18:0), linolenic acid (18:3n3) and nonadecanoic acid (C19-0), were the main fatty acids found in selected mushrooms. The unsaturated fatty acids were predominated over saturated fatty acids. It is concluded that selected mushrooms are good sources of antioxidant compounds and unsaturated fatty acids.

Abstract
Diastolic dysfunction is a major predictor of mortality and morbidity in hypertensive patients. Not only LV, the RV is also expected to be affected in this overall procedure. To observe the Echocardiographic changes of diastolic function of the RV in systemic HTN and their relation with similar parameters of the LV was the objective. TDI was used in association with standard Doppler modality. In this cross-sectional study, 50 hypertensive subjects were studied who were devoid of any other conditions that may influence the diastolic function of the RV from 01 May 2012 to 31 October 2012 at Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. In addition to 2D and M-mode evaluation, standard Doppler and pulsed tissue Doppler assessment of both ventricles were performed. Measurements were obtained for diastolic as well as systolic function of both ventricles. The RV diastolic parameters were impaired in both standard Doppler and tissue Doppler analysis in association with LV parameters. Systolic functions (LV FS and RV TAPSE) were preserved. Doppler-derived tricuspid peak E and E/A were related negatively to septal thickness, but tissue Doppler-derived RV Em/Am showed negative association with both RVAWT and septal thickness. RV RTm was related positively to RVAWT. The RV diastolic parameters showed positive relation with the LV similar parameters both in standard Doppler (E peak velocity, E/A ratio and EDT) and tissue Doppler (Em peak velocity, Em/Am and PCTm) assessment. So, in systemic HTN, LV diastolic dysfunction is also associated with diastolic disturbances of the RV. Pulsed tissue Doppler is a useful tool to detect the changes. RV diastolic parameters correlate well with those of the LV. Prolongation of the active relaxation (RTm) phase of RV is due to its increased wall thickness.

Abstract
Aims: To evaluate the effectiveness and safety of anterior tension band wiring technique using two cannulated cancellous screws in patients with transverse (AO34-C1) or transverse with mildly comminuted (AO34-C2) patellar fractures. Materials and Methods: This is a prospective study of 25 patients with transverse fracture or transverse fracture with mildly comminuted patella fractures. All the patients were treated with open reduction and internal fixation using two parallel cannulated screws and 18G stainless steel wire as per the tension band principle. Results: There were eighteen males (72%) and seven females (28%). The age group ranged from 24 to 58 years, with mean age of 38 years. The most common mode of injury was fall (72%) followed by road traffic accident (20%) and violent quadriceps contraction (8%). Transverse fracture was present in 60% and transverse fracture with mild comminution in 40% of patients. Mean time to achieve union was 10.7 weeks (range 8-12 weeks). Mean ROM at three months was 113.8 degree (90-130) and at final follow up this improved to 125.4 degrees (range 100-140). There was one case of knee stiffness and no case of implant failure was observed. Patients were evaluated using Bostman scoring, the mean score at three months being 26.04 which improved to 27.36 at the end of final follow up at one year. Conclusion: Cannulated cancellous screws with anterior tension band wiring is a safe, reliable and reproducible method in management of transverse patellar fractures, with less chances of implant failure and soft tissue irritation.

Abstract
BACKGROUND The inflammatory bowel diseases (IBD), Crohn's disease (CD) and ulcerative colitis (UC), result from the combined effects of susceptibility genes and environmental factors. Previous studies have shown that polymorphisms in the Toll-like receptor (TLR), the apoptosis, the IL-23/IL-17 and the interferon gamma (IFNG) pathways are associated with risk of both CD and UC. METHODS Using a candidate gene approach, 21 functional single nucleotide polymorphisms (SNPs) in 15 genes were assessed in a clinical homogeneous group of severely diseased ethnic Danish patients consisting of 624 patients with CD, 411 patients with UC and 795 controls. The results were analysed using logistic regression. RESULTS The polymorphisms TLR5 (rs5744174) and IL12B (rs6887695) were associated with risk of CD, and TLR1 (rs4833095) and IL18 (rs187238) were associated with risk of both CD and UC (p<0.05). After Bonferroni correction for multiple testing, the homozygous variant genotype of TLR1 743 T>C (rs4833095) was associated with increased risk CD (OR: 3.15, 95% CI: 1.59-6.26, p = 0.02) and CD and UC combined (OR: 2.96, 95% CI: 1.64-5.32, p = 0.005). CONCLUSION Our results suggest that genetically determined high activity of TLR1 and TLR5 was associated with increased risk of both CD and UC and CD, respectively. This supports that the host microbial composition or environmental factors in the gut are involved in risk of IBD. Furthermore, genetically determined high activity of the IL-23/IL-17 pathway was associated with increased risk of CD and UC. Overall, our results support that genetically determined high inflammatory response was associated with increased risk of both CD and UC.

Abstract
Adolescent females are particularly vulnerable to mental illnesses with co-morbidity of anxiety, such as anorexia nervosa (AN). We used an animal model of AN, called activity-based anorexia (ABA), to investigate the neurobiological basis of vulnerability to repeated, food restriction (FR) stress-evoked anxiety. Twenty-one of 23 adolescent female mice responded to the 1st FR with increased wheel-running activity (WRA), even during the limited period of food access, thereby capturing AN's symptoms of voluntary FR and over-exercise. Baseline WRA was an excellent predictor of FR-elicited WRA (severity of ABA, SOA), with high baseline runners responding to FR with minimal SOA (i.e., negative correlation). Nine gained resistance to ABA following the 1st FR. Even though allopregnanolone (3α-OH-5α-pregnan-20-one, THP), the metabolite of progesterone (P4), is a well-recognized anxiolytic agent, subcutaneous P4 to these ABA-resistant animals during the 2nd FR was exacerbative, evoking greater WRA than the counterpart resistant group that received oil vehicle, only. Moreover, P4 had no WRA-reducing effect on animals that remained ABA-vulnerable. To explain the sensitizing effect of P4 upon the resistant mice, we examined the relationship between P4 treatment and levels of the α4 subunit of GABAARs at spines of pyramidal cells of the hippocampal CA1, a parameter previously shown to correlate with resistance to ABA. α4 levels at spine membrane correlated strongly and negatively with SOA during the 1st ABA (prior to P4 injection), confirming previous findings. α4 levels were greater among P4-treated animals that had gained resistance than of vehicle-treated resistant animals or of the vulnerable animals with or without P4. We propose that α4-GABAARs play a protective role by counterbalancing the ABA-induced increase in excitability of CA1 pyramidal neurons, and although exogenous P4's metabolite, THP, enhances α4 expression, especially among those that can gain resistance, it also interferes with α4-GABAARs' protective role by desensitizing α4-GABAARs.

Abstract
PURPOSE Fractures involving the femur in older adults are reasonably common. The aim of this study was to evaluate the results of MIPO technique using locking plates in geriatric patients for distal extra-articular femur fractures. METHODS About 25 consecutive patients with distal extra-articular femur fractures aged 60 years and above were treated using locking plates and minimally invasive technique. Patients were studied prospectively over a period of 3 years. Parameters studied included patient demographics, fracture type, time taken for the surgery, time to union and any complications. RESULTS Mean age of patients was 66.5 years. Nineteen (76%) patients were females. Most of fractures in our study were type 33A2 fractures (64%). Average time to full weight bearing was 14.32 weeks, and fractures united at an average of 16.88 weeks. There were two (8%) patients with superficial infection, two (8%) with implant tenderness. One (4%) patient developed knee stiffness. Five (20%) patients had extension lag of average 5°. One (4%) patient sustained a peri-implant fracture at 2 months. None of the patients developed non-union or delayed union. According to criteria laid by Schatzker's and Lambert, excellent results were achieved in 22 (88%) patients. CONCLUSIONS Outcome of minimally invasive fixation of distal extra-articular femur fractures with locking plates in patients of age 60 years and above seems to be good with high union rate despite high prevalence of osteoporosis and comminution.

Abstract
BACKGROUND AND PURPOSE Hydrogen sulphide (H2S) is an endogenous gasotransmitter. Although it has been shown to elicit responses in vascular and other smooth muscle preparations, a role for endogenously produced H2S in mediating airway tone has yet to be demonstrated. Therefore, the aim of this study was to determine whether H2S is produced within the airways and to determine the functional effect on airway tone. EXPERIMENTAL APPROACH Small peripheral airways (<5 mm in diameter) from porcine lungs were set up in isolated tissue baths, pre-contracted with the muscarinic agonist carbachol, and then exposed to either the H2S donor sodium hydrosulphide (NaHS), or the precursor L-cysteine. H2S production from L-cysteine or 3-mercaptopyruvate in tissue homogenates was measured by the methylene blue assay. Expression of the H2S-synthesizing enzymes cystathionine β-synthase (CBS), cystathionine γ lyase (CSE) and 3-mercaptopyruvate sulphurtransferase (3-MST) were measured by Western blotting. KEY RESULTS NaHS caused a large relaxation of the airways, which was inhibited partially by pre-contraction with KCl or exposure to tetraethylammonium, but not glibenclamide, paxilline or 4-aminopyridine. L-cysteine also caused a relaxation of the airways which was inhibited by the CBS inhibitor aminooxyacetic acid. Tissue homogenates from airways exposed to L-cysteine or 3-mercaptopyruvate in vitro showed a significant production of H2S. Western blotting demonstrated immunoreactivity to CBS, CSE and 3-MST enzymes in the airways. CONCLUSIONS AND IMPLICATIONS These data demonstrate that H2S can be produced endogenously within porcine airways causing relaxation. The mechanism of relaxation depends, in part, on K(+) channel activity.

Abstract
INTRODUCTION The objective of this study was to evaluate the outcome of anti-tumour necrosis factor-α (anti-TNF) treatment in a large cohort of patients with inflammatory bowel diseases (IBD), including Crohn's disease (CD) and ulcerative colitis (UC) in clinical practice and to establish a cohort for future studies of genetic markers associated with treatment response. METHODS A national, clinically based cohort of previously naïve anti-TNF treated patients from 18 medical departments was established. The patients were screened for tuberculosis prior to treatment initiation. By combining the unique personal identification number of Danish citizens (the CPR number) from blood samples with data from the National Patient Registry, patients with International Classification of Diseases, Version 10 (ICD-10) codes K50-K63 were identified. Treatment efficacy reflected the maximum response within 22 weeks. RESULTS Among 492 patients with CD and 267 patients with UC, 74%/13%/14% and 65%/12%/24% were responders, partial responders and non-responders to anti-TNF therapy, respectively. More patients with UC than with CD were non-responders (odds ratio (OR) = 1.96, 95% confidence interval (CI): 1.34-2.87, p = 0.001). Young age was associated with a beneficial response (p = 0.03), whereas smoking ≥ 10 cigarettes/day was associated with non-response among patients with CD (OR = 2.33, 95% CI: 1.13-4.81, p = 0.03). CONCLUSION In this clinically based cohort of Danish patients with IBD treated with anti-TNF, high response rates were found. Heavy smoking was associated with non-response, whereas young age at treatment initiation was associated with a beneficial response among patients with CD. Thus, the results obtained in this cohort recruited from clinical practice were similar to those previously obtained in clinical trials. FUNDING The work was funded by Health Research Fund of Central Denmark Region, Colitis-Crohn Foreningen and the University of Aarhus (PhD grant). TRIAL REGISTRATION Clinicaltrials NCT02322008.

Abstract
2-Acetylaminofluorene (2-AAF) is a known hepatic carcinogen which leads to tumour formation in rodents. 18-β Glycyrrhetinic acid (18 β-GA) derived from liquorice plant has various pharmacological properties such as anti-ulcer, anti-inflammatory, antiviral, hepatoprotective and antioxidant. This study is designed to elucidate the chemopreventive properties of 18 β-GA against 2-AAF-induced liver toxicity in Wistar rats and evaluated its effect on inflammatory and tumour promotion marker and activities of different oxidative stress enzymes. Administration of 2-AAF at the dose of (50 mg/kg body weight (b.w.) intraperitoneally (i.p.)) for five consecutive days induces hepatic toxicity, inflammation, oxidative stress and hyperproliferation. Pretreatment with 18 β-GA at two different doses (45 and 75 mg kg−1 b.w.) significantly ameliorates 2-AAF-induced increased lipid peroxidation, alanine transaminase and aspartate transaminase, xanthine oxidase activities and activities of phase-II detoxifying enzymes along with the levels of glutathione content. Administration of 18 β-GA also significantly restored the expressions of proliferating cell nuclear antigen, cyclooxygenase 2, inducible nitric oxide synthase and nuclear factor κB. Furthermore, histological observations also support the preventive effects of 18 β-GA. Our findings suggest that pretreatment with 18 β-GA showed potential hepatoprotective effects via attenuation of oxidative stress, inflammation and hyperproliferation.

Abstract
BACKGROUND The inflammatory bowel diseases (IBD), Crohn's disease (CD) and ulcerative colitis (UC), result from the combined effects of susceptibility genes and environmental factors. Polymorphisms in genes regulating inflammation may explain part of the genetic heritage. METHODS Using a candidate gene approach, 39 mainly functional single nucleotide polymorphisms (SNPs) in 26 genes regulating inflammation were assessed in a clinical homogeneous group of severely diseased patients consisting of 624 patients with CD, 411 patients with UC and 795 controls. The results were analysed using logistic regression. RESULTS Sixteen polymorphisms in 13 genes involved in regulation of inflammation were associated with risk of CD and/or UC (p ≤ 0.05). The polymorphisms TLR2 (rs1816702), NFKB1 (rs28362491), TNFRSF1A (rs4149570), IL6R (rs4537545), IL23R (rs11209026) and PTPN22 (rs2476601) were associated with risk of CD and the polymorphisms TLR2 (rs1816702), TLR4 (rs1554973 and rs12377632), TLR9 (rs352139), LY96 (rs11465996), NFKBIA (rs696), TNFA (rs1800629), TNFRSF1A (rs4149570), IL10 (rs3024505), IL23R (rs11209026), PTPN22 (rs2476601) and PPARG (rs1801282) were associated with risk of UC. When including all patients (IBD) the polymorphisms TLR2 (rs4696480 and rs1816702), TLR4 (rs1554973 and rs12377632), TLR9 (rs187084), TNFRSF1A (rs4149570), IL6R (rs4537545), IL10 (rs3024505), IL23R (rs11209026) and PTPN22 (rs2476601) were associated with risk. After Bonferroni correction for multiple testing, both the homozygous and the heterozygous variant genotypes of IL23R G>A(rs11209026) (OR(CD,adj): 0.38, 95% CI: 0.21-0.67, p = 0.03; OR(IBD,adj) 0.43, 95% CI: 0.28-0.67, p = 0.007) and PTPN22 1858 G>A(rs2476601) (OR(CD,unadj) 0.54, 95% CI: 0.41-0.72, p = 7*10-4; OR(IBD,unadj): 0.61, 95% CI: 0.48-0.77, p = 0.001) were associated with reduced risk of CD. CONCLUSION The biological effects of the studied polymorphisms suggest that genetically determined high inflammatory response was associated with increased risk of CD. The many SNPs found in TLRs suggest that the host microbial composition or environmental factors in the gut are involved in risk of IBD in genetically susceptible individuals.

Abstract
Antitumor necrosis factor-α (TNF-α) is used for treatment of severe cases of inflammatory bowel diseases (IBD), including Crohn's disease (CD) and ulcerative colitis (UC). However, one-third of the patients do not respond to the treatment. Genetic markers may predict individual response to anti-TNF therapy. Using a candidate gene approach, 39 mainly functional single nucleotide polymorphisms (SNPs) in 26 genes regulating inflammation were assessed in 738 prior anti-TNF-naive Danish patients with IBD. The results were analyzed using logistic regression (crude and adjusted for age, gender and smoking status). Nineteen functional polymorphisms that alter the NFκB-mediated inflammatory response (TLR2 (rs3804099, rs11938228, rs1816702, rs4696480), TLR4 (rs5030728, rs1554973), TLR9 (rs187084, rs352139), LY96 (MD-2) (rs11465996), CD14 (rs2569190), MAP3K14 (NIK) (rs7222094)), TNF-α signaling (TNFA (TNF-α) (rs361525), TNFRSF1A (TNFR1) (rs4149570), TNFAIP3(A20) (rs6927172)) and other cytokines regulated by NFκB (IL1B (rs4848306), IL1RN (rs4251961), IL6 (rs10499563), IL17A (rs2275913), IFNG (rs2430561)) were associated with response to anti-TNF therapy among patients with CD, UC or both CD and UC (P ⩽ 0.05). In conclusion, the results suggest that polymorphisms in genes involved in activating NFκB through the Toll-like receptor (TLR) pathways, genes regulating TNF-α signaling and cytokines regulated by NFκB are important predictors for the response to anti-TNF therapy among patients with IBD. Genetically strong TNF-mediated inflammatory response was associated with beneficial response. In addition, the cytokines IL-1β, IL-6 and IFN-γ may be potential targets for treating patients with IBD who do not respond to anti-TNF therapy. These findings should be examined in independent cohorts before these results are applied in a clinical setting.

Abstract
The present study was designed to investigate the protective effects of carvacrol against thioacetamide (TAA)-induced oxidative stress, inflammation and apoptosis in liver of Wistar rats. In this study, rats were subjected to concomitant prophylactic oral pretreatment of carvacrol (25 and 50 mg kg(-1) body weight (b.w.)) against the hepatotoxicity induced by intraperitoneal administration of TAA (300 mg kg(-1) b.w.). Efficacy of carvacrol against the hepatotoxicity was evaluated in terms of biochemical estimation of antioxidant enzyme activities, histopathological changes, and expressions of inflammation and apoptosis. Carvacrol pretreatment prevented deteriorative effects induced by TAA through a protective mechanism in a dose-dependent manner that involved reduction of oxidative stress, inflammation and apoptosis. We found that the protective effect of carvacrol pretreatment is mediated by its inhibitory effect on nuclear factor kappa B activation, Bax and Bcl-2 expression, as well as by restoration of histopathological changes against TAA administration. We may suggest that carvacrol efficiently ameliorates liver injury caused by TAA.
