Abstract
BACKGROUND Healthcare and support workers play a pivotal role in delivering quality services and support to people seeking sanctuary who have experienced poor physical and mental health linked to previous trauma, relocation and loss of freedoms. However, they often encounter various challenges in their daily work, ranging from communication barriers to resource constraints. This qualitative study seeks to delve into the perspectives of healthcare and support workers' experience of workarounds, employed to overcome barriers to providing care. AIM This study aims to describe healthcare providers', practitioners' and health and third sector support workers' views on barriers and workarounds to providing care for people seeking sanctuary, to inform policy and practice. DESIGN A qualitative study was carried out using semi-structured telephone interviews. SETTING This study focused on primary, secondary, community and specialist National Health Service (NHS) support services for people seeking sanctuary in Wales, United Kingdom (2018). METHOD We interviewed 32 healthcare providers, practitioners and support workers employed by primary care and third sector organisations. Our approach involved obtaining verbal informed consent before digitally recording and transcribing all interviews. To analyse the data, we used the Four Levels of Change for Improving Quality model as a guiding framework for interpretation. RESULTS Our study findings reveal that certain respondents expressed challenges in meeting the needs of people seeking sanctuary; notably, their experience of delivering care differed by care settings. Specifically, those involved in providing specialist NHS care believed that there was room for improvement. Mainstream primary, secondary and community health practitioners faced limitations due to resource constraints and lacked tailored information to address the unique circumstances and needs of sanctuary seekers. To address these gaps, workarounds emerged at both individual and local levels (team/departmental and organisational level). These included establishing informal communication channels between providers, fostering cross service collaboration to fill gaps and adapting existing services to enhance accessibility. CONCLUSION Understanding healthcare providers', practitioners' and support workers' perspectives offers invaluable insights into ways to enhance healthcare delivery to sanctuary seekers. Acknowledging challenges and harnessing innovative workarounds can foster a more effective and compassionate service for this vulnerable population. PATIENT OR PUBLIC CONTRIBUTION The HEAR study actively involved public contributors in the design, delivery and dissemination of the research. Two public contributors (S. M. and G. R.) who had personal experience of seeking asylum served as study co-applicants. They played pivotal roles in shaping the research by participating in its development and securing funding. Alongside other co-applicants, S. M. and G. R. formed the Research Management Group, overseeing study delivery. Their contributions extended to strategic decision-making and specific feedback at critical junctures, including participant recruitment, data collection, analysis and reporting. Additionally, S. M. and G. R. were instrumental in recruiting and supporting a team of peer researchers, enhancing respondent participation among people seeking sanctuary. To facilitate effective public involvement, we provided named contacts for support (A. K. and R. F.), research training, honoraria, reimbursement of expenses and accessible information in line with best practice.

Abstract
Compared to classical techniques of morphological analysis, micro-CT (μ-CT) has become an effective approach allowing rapid screening of morphological changes. In the present work, we aimed to provide an optimized micro-CT dense agent perfusion protocol and μ-CT guidelines for different stages of chick embryo cardiogenesis. Our study was conducted over a period of 10 embryonic days (Hamburger-Hamilton HH36) in chick embryo hearts. During the perfusion of the micro-CT dense agent at different developmental stages (HH19, HH24, HH27, HH29, HH31, HH34, HH35, and HH36), we demonstrated that durations and volumes of the injected contrast agent gradually increased with the heart developmental stages contrary to the flow rate that was unchanged during the whole experiment. Analysis of the CT imaging confirmed the efficiency of the optimized parameters of the heart perfusion.

Abstract
INTRODUCTION Traditional chemotherapy dosing is based on body surface area (BSA) using standard formulas, which can pose challenges in dosing patients at body weight extremes. Studies suggest that chemotherapy dosing according to actual body weight does not increase toxicity in obese patients and current guidelines recommend full weight-based dosing of chemotherapy regardless of body mass index (BMI). However, the dosing of anthracyclines in obese patients can be challenging given limitations in maximum cumulative dosage, particularly in those at very extreme BMI. In this case, we highlight the difficulties of dosing anthracycline-based induction chemotherapy in a patient with newly diagnosed acute myeloid leukemia (AML) and BMI >90 kg/m2. CASE REPORT A 40-year-old female with morbid obesity is diagnosed with AML (nucleophosmin 1 (NPMI) and isocitrate dehydrogenase-2 mutated, FMS-like tyrosine kinase 3-Internal tandem duplication negative). MANAGEMENT AND OUTCOME The patient was initiated on induction therapy with 7 + 3 with dose capping of BSA at 2.75 m2 (cytarabine 200 mg/m2 continuous infusion over 24 h for 7 days, plus daunorubicin 60 mg/m2 slow intravenous push for 3 days), followed by two cycles of high-dose cytarabine consolidation therapy using actual BSA. The patient achieved morphologic complete remission; however, measurable residual disease testing for NPM1 remained positive after induction therapy. DISCUSSION This case suggests that dose capping of anthracyclines in the treatment of newly diagnosed AML may be an effective and safe treatment alternative in those with extreme BMI elevations beyond what has been studied in the literature. Given the increasing incidence of morbid obesity, further studies are needed to confirm appropriate dosing of anthracycline-based regimens at upper BMI extremes (>60 kg/m2).

Abstract
Abstract The present study examines the correlations between fifteen morphometric and ten meristic characters and total length (TL) of males, females, and combined sexes of Alepes vari (Cuvier, 1833) collected from Karachi fish harbor, West Wharf of Karachi Coast. Statistical analyses of linear regression relationships show mostly strong correlations (r≥0.70; p<0.05) between total length (TL) and most morphometric characters in males, females, and combined sexes, except the height of pectoral-fin (PFH), and pelvic-fin base length (PelFL); whereas, meristic characters were found to be constant and indicate weak or negative type correlations (r≤0.50; p>0.05) with total length (TL). Hence, according to our present results, there is a direct relationship between the total length of fish and all morphometric characters, which were found to be the best indicators of positive allometric pattern growth in fish. Moreover, analysis of the 2-sample t-test revealed (t-test; p>0.05) that no sexual dimorphism was reported in Alepes vari. Thus, our present study could be valuable in systematic classification, sexual dimorphism, and management of this species on the Karachi coast.

Abstract
Advances in deep vision techniques and the ubiquity of smart cameras will drive the next generation of video analytics. However, video analytics applications consume vast amounts of energy as deep learning techniques are power-hungry. In this article, we focus on a parking video analytics platform and propose RL-CamSleep, a deep reinforcement learning-based technique, to actuate the cameras to reduce the energy footprint while retaining the system’s utility. Our key insight is that many video-analytics applications do not need to be always operational, and we can design policies to activate video analytics only when necessary. We design two modes of operation for the reinforcement learning (RL) controller: (i) cloud-based mode and (ii) grid-isolated solar-powered mode. In the cloud-based mode, the controller runs on the cloud to control the cameras, whereas, in the solar-powered mode, the RL controller is constrained by the energy produced by solar. We evaluate our approach on a city-scale parking dataset having 76 streets spread across a city. Our analysis shows RL-CamSleep can learn an adaptive policy that reduces the average energy consumption by 76% and achieves an average accuracy of 98%. For the grid-isolated mode, RL-CamSleep outperforms other baseline techniques demonstrating the need for adaptive policy in energy-constrained environments.

Abstract
Latency is a pervasive issue in various systems that can significantly impact motor performance and user perception. In medical settings, latency can hinder surgeons' ability to quickly correct movements, resulting in an experience that doesn't align with user expectations and standards of care. Despite numerous studies reporting on the negative effects of latency, there is still a gap in understanding how it impacts the use of augmented reality (AR) in medical settings. This study aims to address this gap by examining how latency impacts motor task performance and subjective perceptions, such as cognitive load, on two display types: a monitor display, traditionally used inside an operating room (OR), and a Microsoft HoloLens 2 display. Our findings indicate that both level of latency and display type impact motor performance, and higher latencies on the HoloLens result in relatively poor performance. However, cognitive load was found to be unrelated to display type or latency, but was dependent on the surgeon's training level. Surgeons did not compromise accuracy to gain more speed and were generally well aware of the latency in the system irrespective of their performance on task. Our study provides valuable insights into acceptable thresholds of latency for AR displays and proposes design implications for the successful implementation and use of AR in surgical settings.

Abstract
Magnesium alloys containing biocompatible components show tremendous promise for applications as temporary biomedical devices. However, to ensure their safe use as biodegradeable implants, it is essential to control their corrosion rates. In concentrated Mg alloys, a microgalvanic coupling between the α-Mg matrix and secondary precipitates exists which results in increased corrosion rate. To address this challenge, we engineered the microstructure of a biodegradable Mg-Zn-RE-Zr alloy by friction stir processing (FSP), improving its corrosion resistance and mechanical properties simultaneously. The FS processed alloy with refined grains and broken and uniformly distributed secondary precipitates showed a relatively uniform corrosion morphology accompanied with the formation of a stable passive layer on the alloy surface. In vivo corrosion evaluation of the processed alloy in a small animal model showed that the material was well-tolerated with no signs of inflammation or harmful by-products. Remarkably, the processed alloy supported bone until it healed till eight weeks with a low in vivo corrosion rate of 0.7 mm/year. Moreover, we analyzed blood and histology of the critical organs such as liver and kidney, which showed normal functionality and consistent ion and enzyme levels, throughout the 12-week study period. These results demonstrate that the processed Mg-Zn-RE-Zr alloy offers promising potential for osseointegration in bone tissue healing while also exhibiting controlled biodegradability due to its engineered microstructure. The results from the present study will have profound benefit for bone fracture management, particularly in pediatric and elderly patients.

Abstract
Objective: To find out the association of workplace support on breastfeeding self-efficacy among working mothers of Attock city and the association of breastfeeding self-efficacy with their socio-demographics. Methodology: The study employed a cross-sectional study design. Data were gathered from public & private organizations including secondary care hospitals, banks, schools, colleges/universities, and parlors of Attock city. It was a six months’ study from July to September 2021.The study was conducted with 369 working mothers. A consecutive non-probability sampling technique was used. Data was collected by a validated tool, which consisted of two questionnaires: WBBSS (workplace breastfeeding support scale) and BSEF-SF (breastfeeding self-efficacy scale short form) questionnaire. Data analysis was done through SPSS version 20. Pearson Correlation was employed to determine the association between support at the workplace and the self-efficacy of breastfeeding. Results: Statistically significant relationship between workplace support for breastfeeding and maternal self-efficacy (r= 0.375 and p-value= 0.0001). Conclusion: Support at the workplace was significantly related to the self-efficacy of breastfeeding. Further research is required to understand breastfeeding policies at a workstation that increase the self-efficacy of working mothers in attaining their goals of breastfeeding.

Abstract
<p>Backscatter communications can enable the proliferation of Zero-energy (ZE) Internet of Things (IoT) services in 6G, ushering in a new era in green communications. To achieve a widescale adoption, backscatter communications needs to be integrated into the cellular ecosystem. This motivates the need to design a bistatic backscatter modulation technique which is not only compatible with the 3GPP New Radio (NR) physical layer but also robust to direct link interference. In this paper, a non-ambient bistatic backscatter communications system consisting of a cellular carrier emitter (CE), a backscatter device (BD) and a cellular reader (RD) is investigated. An analytical model is presented to explain the design rationale for an orthogonal frequency division multiplexing (OFDM) based physical layer for the considered system. Specifically, to achieve orthogonality between the CE and BD signals arriving concurrently at the RD, a comb-like OFDM subcarrier allocation is leveraged at the CE while a specially designed impedance switching sequence is applied at the BD to generate OFDM-compatible backscatter symbols with a binary or higher-order phase shift keying modulation. The link performance of the proposed system is evaluated in terms of the achievable bit error rate versus the signal-to-noise ratio at the RD for the CE-RD link and the BD-RD link under direct link interference. Simulation results confirm the viability of the proposed design for a cellular ZE-IoT system.</p>

Abstract
The calcium sensing receptor (CaSR) plays an important role in maintaining calcium homeostasis. The use of calcimimetic cinacalcet has been established to activate CaSR and normalize hypercalcemia. However, cinacalcet has limitations due to its high cLogP and pKa. A systematic optimization of cinacalcet to reduce its cLogP and pKa yielded compound 23a (LNP1892). Compound 23a showed excellent potency and a favorable pharmacokinetics profile, and lacked the liabilities of cinacalcet, making it a highly differentiated precision calcimimetic. In adenine-diet-induced chronic kidney disease (CKD) models, 23a demonstrated robust and dose-dependent efficacy, as measured by plasma parathyroid hormone (PTH) levels. It also showed an excellent safety profile in animal studies. Phase 1 clinical trials with 23a in healthy volunteers confirmed its excellent safety, tolerability, and effectiveness in lowering PTH levels in a dose-dependent manner, without causing symptomatic hypocalcaemia. Encouraged by these promising results, LNP1892 was taken to a Phase 2 study in CKD patients.

Abstract
Diversified techniques have been applied in many research papers for the optimization of rehabilitation robotic movements in order to maintain smoothness and accuracy. Smooth and precise control is needed necessarily for upper limb rehabilitation robotic applications having five degree of freedom. The preferred parameters which are used for the controlling were validated by mathematical model and these tuning parameters were optimized. Designing optimization algorithms to control complex physical robots has been a challenging task. In this study, a number of optimization techniques will be analyzed to determine the optimal parameters of a PID controller with a dynamic model of the upper limb rehabilitation system. For determining optimal control parameters for PID, there exists a number of tuning methods such as Zeigler Nichols and fuzzy logic which are classical methods. Swarm intelligence-based optimization algorithms are inspired by the behaviors of living things in nature. Several researchers have reported the optimal design of PID controller parameters using optimization techniques. The proposed control technique has been implemented on a 5-DOF RAX hardware and before any clinical trials, six healthy subjects went for trials under strict protocol. It has been discovered that the proposed control technique rejects the external unwanted disturbances as well as keeps the system stable under extreme perturbed and harsh conditions. In this research paper mathematical models have been validated to determine the PID parameters for the optimization. The comparative study is carried out with four different cost functions since a well-designed objective function leads to better performance of the system and indicates control design expectations. These objective functions are an integral squared error (ISE) and integral absolute error (IAE). In this research work, the effects of different cost functions on optimization techniques for controller parameters were analyzed. The performance of the controller with different cost functions has examined for robustness analysis. The cost function of particle swarm optimization, Firefly, Ant Bee Colony and Ant Colony optimization were developed for the better optimization results.

Abstract
The disproportionate use of petroleum products and stringent exhaust emissions has emphasized the need for alternative green fuels. Although several studies have been conducted to ascertain the performance of acetone-gasoline blends in spark-ignition (SI) engines, limited work has been done to determine the influence of fuel on lubricant oil deterioration. The current study fills the gap through lubricant oil testing by running the engine for 120 h on pure gasoline (G) and gasoline with 10% by volume acetone (A10). Compared to gasoline, A10 produced better results in 11.74 and 12.05% higher brake power (BP) and brake thermal efficiency (BTE), respectively, at a 6.72% lower brake-specific fuel consumption (BSFC). The blended fuel A10 produced 56.54, 33.67, and 50% lower CO, CO2, and HC emissions. However, gasoline remained competitive due to lower oil deterioration than A10. The flash-point and kinematic viscosity, compared to fresh oil, decreased by 19.63 and 27.43% for G and 15.73 and 20.57% for A10, respectively. Similarly, G and A10 showed a decrease in total base number (TBN) by 17.98 and 31.46%, respectively. However, A10 is more detrimental to lubricating oil due to a 12, 5, 15, and 30% increase in metallic particles like aluminum, chromium, copper, and iron, respectively, compared to fresh oil. Performance additives like calcium and phosphorous in lubricant oil for A10 decreased by 10.04 and 4.04% in comparison to gasoline, respectively. The concentration of zinc was found to be 18.78% higher in A10 when compared with gasoline. A higher proportion of water molecules and metal particles were found in lubricant oil for A10.

Abstract
Abstract
Compared to classical techniques of morphological analysis, micro-CT (µ-CT) has become an effective approach allowing rapid screening of morphological changes. In the present work, we aimed to provide an optimized µ-CT dense agent perfusion protocol and µ-CT guidelines for different stages of chick embryo cardiogenesis. Our study was conducted over a period of 10 embryonic days (Hamburger-Hamilton HH36) in chick embryo hearts. During the perfusion of the µ-CT dense agent at different developmental stages (HH19, HH24, HH27, HH29, HH31, HH34, HH35, and HH36), we demonstrated that durations and volumes of the injected contrast agent gradually increased with the heart developmental stages contrary to the flow rate that was unchanged during the whole experiment. Analysis of the CT imaging confirmed the efficiency of the optimized parameters of the heart perfusion.

Abstract
Abstract
Introduction
Both frailty and HF are common in the elderly population. Elderly HF patients have an increased risk of frailty and elderly frail patients are at a higher risk of developing HF. Frailty is an independent predictor of mortality in cardiovascular disease. Sarcopenia (defined as decreased muscle mass and muscle strength and/or performance) is also prevalent in HF patients and may progress to cardiac cachexia. HF may induce sarcopenia and sarcopenia may contribute to the poor prognosis of HF.
Aims
Methods
A cross-sectional, retrospective analysis of consecutive patients, 60 years and over, admitted with HF to a UK hospital. Data was manually extracted from anonymized electronic records. The Rockwood Clinical Frailty Scale (CFS) was used for assessment for frailty and the SARC-F tool was used for screening for sarcopenia. Patients with medical history of HF but did not present with decompensated HF were excluded. Also, patients with incomplete data were excluded. The IBM SPSS 28 statistical package was used for statistical analysis. Descriptive statistics and risk estimates were calculated.
Results
163 patients were analysed; 82 males and 81 females. The mean age was 81.4 years (SD 9.69). 71.5 % of patients were frail while 28.5 % were non-frail. The risk of sarcopenia was 10.9 times greater in the frail than in the non-frail patients (OR = 10.9; 95% C.I 4.85 – 24.67). There was a lower risk of sarcopenia in male patients than in the female patients (OR =0.45; 95% C.I 0.22 – 0.94).
Conclusions
Frailty is prevalent in older heart failure inpatients. It significantly increases the risk of sarcopenia in these patients. Women are at higher risk of sarcopenia than men. More research is needed into frailty and sarcopenia in.

Abstract
Introduction
Co-morbidities and frailty are common in older heart failure patients. The aim of this study is to explore the relationship between co-morbidity, frailty and ejection fraction (EF) in older heart failure inpatients
Methods
A cross-sectional, observational, retrospective analysis of consecutive patients aged 60 years and over who were admitted with heart failure in a UK hospital. Patients with incomplete data were excluded. The Carlson’s comorbidity index (CCI) was used to compute comorbidity and the Rockwood Clinical Frailty Scale (CFS) was used to measure frailty. The EF was calculated as the midpoint of the ranges measured by echocardiography. IBM SPSS 28 software was used for statistical analysis. Descriptive statistics were used to measure baseline characteristics and Pearson’s correlation coefficient and linear regression were used to calculate correlation.
Results and discussion
101 patients were analysed; 48 males and 53 females. Mean age was 81.2 years(SD 9.98). Mean CCI was 6.97(SD 1.63) and mean CFS was 5.09(SD 1.14). There was statistically significant positive correlation between CCI and CFS (r= 0.232; p= .01). There was statistically significant inverse correlation between CCI and EF (r= -.277; p=. 005). When taking into account the level of frailty the correlation between CCI and EF was much stronger in non-frail than in frail patients (r= -.612; p=. 035 and r= -.216; p= .047 respectively). There was no correlation between CFS and EF (r= .095; p=.26). This was not surprising as HFpEF is the most common type of HF in the elderly. HFpEF patients are more likely to have more comorbidities and to be more frail compared to HFrEF patients.
Conclusion
There was a positive correlation between multi-morbidity and frailty in older inpatients admitted with heart failure. There was statistically significant inverse correlation between CCI and ejection fraction but there was no correlation between frailty and ejection.

Abstract
With the advent of augmented reality (AR), the use of AR-guided systems in the field of medicine has gained traction. However, the wide-scale adaptation of these systems requires highly accurate and reliable tracking. In this work, the tracking accuracy of two technology platforms, LiDAR and Vuforia, are developed and rigorously tested for a catheter placement neurological procedure. Several experiments (900) are performed for each technology across various combinations of catheter lengths and insertion trajectories. This analysis shows that the LiDAR platform outperformed Vuforia; which is the state-of-the-art in monocular RGB tracking solutions. LiDAR had 75% less radial distance error and 26% less angle deviation error. Results provide key insights into the value and utility of LiDAR-based tracking in AR guidance systems.

Abstract
Abstract
Background
Cardiac syncope occurs when the heart fails to maintain cardiac output to match cerebral need and can occur due to either mechanical/structural defect of the heart or secondary to an arrhythmia. It has a raised 1-year mortality with some figures estimating this as high as 30%. Implantable loop recorders (ILR) are a useful diagnostic tool in patients presenting with syncope or pre-syncope to ascertain a cardiac cause. A higher number of patients are presenting with advancing age and undergoing ILR implantation. Subsequently, they end up requiring a cardiac implantable electronic device (CIED) implantation, adding to additional costs, exposure to procedural complications and frequent hospitalisations.
Purpose
To investigate the number of patients undergoing CIED implantation following implantation of ILRs for syncope and identify predictors of CIED implantation in patients presenting with syncope.
Methods
A retrospective analysis of 736 patients who underwent ILR implantation at our teaching hospital trust between November 2012 to October 2020. Data on demographics, clinical characteristics, pathology results, ECGs, holter findings and CIED implanted was collected using the local electronic patient record system. The data was analysed using SPSS software. Univariable and multivariable regression analysis and ROC curve analysis was carried out to determine prediction model for CIED implantation.
Results
The mean age of patients who underwent an ILR implantation was 65±19 years. 22% of patients required CIED implantation, 68% of patients did not require a cardiac device and were safely discharged and 10% of patients died during follow up. Age (p<0.001), male sex (p=0.006), impaired left ventricular function (p=0.04) and presence of hypertension (p=0.04) were found to be independent predictors of CIED implantation on univariable and multivariable regression analysis (see Table 1).
Conclusions
Old age, presence of coronary artery disease, impaired left ventricular function and presence of hypertension are inter-linked and in our study were found to be key predictors of poor prognosis and thus requiring CIED implantation. We propose a scoring system based on age >75, male sex, presence of ischaemic heart disease, heart failure and hypertension as key markers of conduction abnormalities requiring CIED implantation (see fi−ure 1).

Abstract
BACKGROUND Understanding the different skeletal relationships in orofacial clefts by using cone-beam computed tomography (CBCT) may eventually lead to developing better diagnosis and treatment protocols for facial deformities. AIMS The objective of this study was to investigate the different skeletal relationships in the cleft palate with or without cleft lip (CP ± L), using CBCT scans. This is a retrospective study conducted at the Orthodontics and Oral Radiology department, CMH-Lahore medical college and Institute of dentistry. In the current study, 4,152 CBCT scans (dcm format) were collected from a radiology center in Lahore, Pakistan between February 2015 and February 2018. All CBCT scans were imported to the Romexis Viewer, version 4.4.0 (Planmeca, Finland). Data sorting was performed to identify age, sex, cleft phenotype, unilateral cleft quadrant, sagittal skeletal relationship, and facial soft tissue involvement. MATERIALS AND METHODS Statistics were generated, using the Chi-square test. A P value <0.05 was considered statistically significant. RESULTS We identified 73 cases of CP ± L in the sample. The male-to-female ratio was 1.21:1. Bilateral cleft lip and palate (BCLP) mostly affected males (60%), whereas unilateral cleft lip and palate (UCLP) mainly affected females (57.6%), with a left-side female predominance. The different cleft phenotypes do not show any statistically significant difference regarding skeletal relationships and sex (P > 0.05). CONCLUSIONS Skeletal class III relationships were found to be predominant in both sexes, followed by class II, and class I skeletal relationships. Henceforth, such CP ± L patients should be pre-emptively screened in early life to avoid such skeletal complications.

Abstract
Abstract
Aim
Has lockdown and COVID-19 led to a change into the characteristics of DVT's and patients who have them alongside a review of the DVT service.
Method
Data was collected retrospectively from electronic patient records system for the following periods: 1st April until 30th June 2019 and 1st April until 30th June 2020. These were the key months during the first United Kingdom national lockdown. Data was analysed for patient demographics, risk factors, characteristics of the DVT, management and DVT reoccurrence. Statistical analyses were preformed using GraphPad Prism 8.
Results
227 patients sustained community DVT's in 2019 and 211 patients in 2020 during the study period. 13 of these patients in 2020 were COVID-19 positive. There was a difference in gender distribution (p= 0.0128) with 128 males and 99 females in 2019, 93 males and 118 females in 2020. No significant difference was noted for the incidence of thrombophilia with 9 in 2019 and 3 in 2020 (p=0.1437). Fewer long-haul journeys were made (p=0.012) with 16 in 2019 and only 2 in 2020. Fewer patients had immobility as a risk factor with 79 in 2019 and 55 in 2020 (p=0.0494). However, there were more patients using the contraceptive pill (p=0.0086) with 1 in 2019 and 9 in 2020.
Conclusion
There is no significant difference in the characteristics, extent, and management of DVT's prior to and during Lockdown during COVID-19. National Lockdowns do not affect community DVT's however it is important to highlight the surrounding inpatient numbers.

Abstract
Motion sign-based language has an important role in the mute community, that is for data transmission. Usually, silent and dumb people counter very difficult situations to convey information to normal people. This paper proposes research that can ease the life of the deaf community. The work presented in this paper is a communication bridge between normal-hearing persons and persons with less hearing ability or impaired persons. The proposed research ‘Gesture–Talk’ can be used as an interpreter between any normal person and deaf and mute persons. The Gesture–Talk is based on the language used in Pakistan which is Pakistan Sign Language (PSL), which is a standard language used by deaf persons in Pakistan. Using Gesture–Talk, PSL can be translated into voice. The idea is to develop a small portable application that can be used as a middle layer application between normal and deaf people. The authors have used an electrical sensor that will collect the data by detecting electrical pulses that will be sent to the microcomputer (raspberry pi 3) where the data will be processed and sent to the speaker from which voice will be generated. A cost-effective and novel approach has been proposed in this research paper compared to the other existing approaches. Moreover, Artificial Intelligence (AI) based predictive or classification algorithms may be applied for the best optimal results.

Abstract
Collectively known as congenital heart defects (CHDs), cardiac abnormalities at birth are the most common forms of neonatal defects. Being principally responsible for the heart‘s pumping power, ventricles are particularly affected by developmental abnormalities, such as flow disturbances or genomic defects. Hypoplastic Right Heart Syndrome (HRHS) is a rare disease where the right ventricle is underdeveloped. In this study, we introduce a surgical procedure performed on chick embryo, termed right atrial ligation (RAL) for disturbing hemodynamics within the right heart aiming in order to generate an animal model of HRHS. RAL is a new surgical manipulation, similar to the well-studied left atrial ligation (LAL) surgery but it induces the hemodynamic change into the right side of the heart. After inducing RAL, We utilized techniques such as Doppler ultrasound, x-ray micro-CT, histology, and computational fluid dynamics (CFD) analysis, for a comprehensive functional and structural analysis of a developing heart. Our results displayed that RAL does not induce severe flow disturbance and ventricular abnormalities consistent with clinical findings. This study allows us to better understand the hemodynamics-driven CHD development and sensitivities of ventricles under disturbed flows.

Abstract
Gastrointestinal (GI) Parasitic infection is a hot issue for cattle management. There is variation of GI parasites effects in sex, age of cattle, drinking water condition, nutrition, and severity of infection. Studies on prevalence of GI parasites among cattle population in Dir Lower are lacking. A total of 40 farms were selected randomly in six tehsil namely Tehsil Adenzai, Tehsil Timergara, Tehsil Balambat, Tehsil Munda ,Tehsil Lalqala, Tehsil Khall. Freshly cattle fecal samples were collected randomly from the selected farms during March 2018 till December 2018. Out of 314 buffaloes and cattle examined 58.59% (184/314) were positive for eggs, cyst/oocyst of one or more species of GI Parasites. The prevalence of parasitic infection was higher in Buffaloes 63.55% (75/118) as compared to Cow 55.61% (109/196) but the difference was not significant (p>0.05) Entamoeba,spp, Moniezia spp, Haemonchus spp and Coccidian spp were found in this study. The non-treated animals indicated the highest percentage of infection in cow 57.71% (101/175) and buffalo 68.13% (62/91).GI parasite prevalence in female animal were higher female cow 62.58% (87/139) and female buffalo 77.33% (58/75) as compared to male. But the difference is non-significant (p> 0.05) Yearling calves had the lower rate of GI parasitic infection than adults. Future investigations are necessary to evaluate the economic loss due to GI parasites in cattle's.

Abstract
A seven day safety net telephone service was developed in an acute medical unit at a university hospital in London. The service attempts to provide all patients discharged from acute medicine with patient activated access to a member of the acute medical team. This allows patients to flag deterioration triggering further review in the ambulatory clinic or to ask for advice on symptoms or medication. Here we evaluate the first sixteen months of the service and report on its benefits and limitations.

Abstract
Abstract Bauhinia variegata plant is a very popular and traditionally potent ethnomedicine. Therefore, it is need of hour to study ameliorative characteristics of B. variegata for novel secondary metabolites. The current study was designed to explore antiproliferative potential of B. variegata due to scant reports on this aspect. Extracts of various parts (flowers, leaves, bark, stem, and roots) were prepared by successive maceration using organic solvents in increasing order of polarity (n-hexane, ethyl acetate, methanol, and water). The determination of polyphenolic contents was done by using colorimetric methods while antioxidant potential was measured using reducing power assay. Brine shrimp lethality assay was performed for determining preliminary cytotoxicity and antiproliferative activity against breast cancer MCF-7 cell line using MTT protocols. Moreover, antimicrobial activities were detected by using disc diffusion assay. The alpha-amylase assay was performed to monitor the antidiabetic potential of the plant. In case of phytochemical analysis methanolic extract of leaves and bark showed highest phenolic and flavonoids contents. n-Hexane and ethyl acetate extracts of stem and roots exhibited more than 90% mortality with LD50 ranges between 1-25 µg/mL when studied by brine shrimp lethality assay. n-Hexane and ethyl acetate extracts of roots and stem also showed antiproliferative activity against human breast cancer MCF-7 cell line with IC50 values ranges between 12.10-14.20 µg/mL. Most of the extracts displayed moderately high antibacterial and antifungal activities. The n-hexane extract of roots showed antidiabetic activity with 60.80 ± 0.20% inhibition of alpha-amylase. In sum, these preliminary results will be useful for further compound isolation from selected plant parts for the discovery of antibacterial, antidiabetic, and anticancer lead candidates.

Abstract
Being vector of West Nile Virus and falariasis the control of Culex quinquefasciatus is likely to be essential. Synthetic insecticide treatment is looking most effective for vectors mosquito control. However, these products are toxic to the environment and non-target organisms. Consequently, ecofriendly control of vectors mosquito is needed. In this regard botanical insecticide is looking more fruitful. Therefore, the present research aimed to investigate the effectiveness of methanolic extract and various fractions, including, n-hexane, ethyl-acetate, chloroform, and aqueous fraction, obtained from methanolic extract of Ailanthus altissima, Artemisia scoparia, and Justicia adhatoda using separating funnel against larval, pupal, and adult stages of Culex quinquefasciatus. The larvae and pupae of Culex quinquefasciatus were exposed to various concentrations (31.25-1000 ppm) of methanolic extract and its fractions for 24 hours of exposure period. For knock-down bioassay (filter paper impregnation bioassay) different concentration of the methanolic extract and its various fractions (i.e. 0.0625, 0.125, 0.25, 0.5 and 1mg/mL) were applied for 1 hour exposure period. The results were statistically analysed using standard deviation, probit analysis, and linear regression. The R2 values of larvae, pupae, and adult range from 0.4 to 0.99. The values of LC50 (concentration causing 50% mortality) for late 3rd instar larvae after 24 hours exposure period range from 93-1856.7 ppm, while LC90 values range from 424 -7635.5ppm. The values of LC50for pupae range form 1326.7-6818.4ppm and and values of LC90 range from 3667.3-17427.9ppm, respectively. The KDT50 range from 0.30 to 2.8% and KDT90 values range from1.2 to 110.8%, respectively. In conclusion, Justicia adhatoda may be effective for controlling populations of vector mosquito.

Abstract
The present research was planned to assess the occurrence of intestinal parasites in small ruminants of Upper Dir of Khyber Pakhtunkhwa Province of Pakistan. For this purpose, the faecal material was collected randomly with gloved fingers directly from the rectum region of sheep and goats and the faecal materials were then put in hygienic plastic bottles with 10% formalin. The overall 315 (n=184 sheep and n= 131 goats) faecal samples were collected out of 315 samples, 281 were found positive for different parasites. Patterns-wise prevalence of GI parasites of the study area was found. Overall Single parasitism 89.20% (281/315) with 94.0% (173/184) in sheep and 82.43% (108/131) in goats. Double parasitic infection in small ruminant recorded in which Fasciola+ Haemonchus. contortus in sheep were found their prevalence was 25.54% (47/184). While in goats, the double parasitic infection in which Haemonchus contortus+Trichuris spp were found and their prevalence were 23.43% (30/131). The species found in the sample of sheep were includes, i.e., Strongyloides papillosus (41.30%), Heamonchus controtus (21.73%), Trichuris ovis (17.39%), and Fasciola hepatica (13.58%), the corresponding value for goat were Strongyloides spp 33.33% (36/108), Haemonchus spp 28.70%, (27/108), Trichuris spp 25.20% (27/184) and Fasciola spp 10.68% (14/184). The sheep of the study area are more infected as compared to goats. This study suggested that gastrointestinal parasites are major health problems of small ruminants in the study area. Therefore, a comprehensive study on species of gastrointestinal parasites circulating in the area, control options, cost-effective strategies and awareness about gastrointestinal parasites among the farmers in the study area should be instituted.

Abstract
The present study describes the haematological profile, feeding preference, and comparison of morphometric characters of blue rock pigeon (Columba livia) breeding pairs. For this purpose, 25 pairs (25 samples per sex) were sampled through Mist nets from district Okara and Bahawalnagar, Punjab, Pakistan. Birds were then anaesthetized with a combination of ketamine HCL (10 mg/kg) and diazepam (0.2 mg/kg) and subjected to morphometric measurements. 5µL blood also was taken from the jugular vein of each anaesthetized bird for haematological analysis. Few pairs were also dissected to remove gastrointestinal tracts (GITs) for food preferences. Results revealed that there are no significant differences in the haematological parameters and feeding preference of breeding pairs of Columba livia. The gut analysis further revealed, the major portion of gut contents consisted of pea and corn in most of the pairs. Regarding the mensural measurements, significant differences were recorded in the body weight, length of the longest primary feather, and chest circumference, whereas the rest of the studied parameters remain nonsignificant between sexes. So, it is concluded that apart from 3 morphometric parameters (body weight, length of longest primary feather and chest circumference), both sexes are alike in term of morphometry, haematology and food preference.

Abstract
Aim
Incisional hernias (IH) are a known complication of any major abdominal surgery. It is known that chemotherapy impairs healing processes via delayed inflammation, impaired collagen synthesis and reduced fibrin deposition and wound contraction. There are currently, to our knowledge, no trials examining the effect of adjuvant chemotherapy on incidence of IH in patients with colorectal cancer. This study aims to assess the same by comparing IH rates between chemotherapy and non-chemotherapy patient groups.
Method
All the patients who had major surgery for colorectal cancer between January 2009 and January 2014 were divided into two groups of chemotherapy (A) and non-chemotherapy (B). Records of first 160 patients from each group were retrospectively analysed.
Results
There were non-significant differences between groups for sex, tumour location, primary operation, and type of procedure (emergency or elective). Significant differences were observed for age (more elder patients in group B, p = 0.000011), method of access (more open procedures in group B and more laparoscopic procedures in group A, p = 0.0007) and Charlson co-morbidity scores (more advanced score in group B, p = 0.029). We found that 21/120 (21.21%) patients in the chemotherapy group and 12/99 (13.79%) patients in non-chemotherapy group developed Incisional hernias. Although there was a higher rate of IH in the chemotherapy group, this was not statistically significant (p = 0.27).
Conclusions
Although this study fails to demonstrate any statistically significant difference in IH incidence between two groups, but this study can act as a pilot in order to fuel further high-quality research to draw more valid conclusions.

Abstract
Complete assessment of obstructive jaundice requires the use of various imaging modalities that are required to detect the cause and level of obstruction thus helping in treatment planning. Magnetic Resonance Cholangio Pancreatography (MRCP) is a current available technology which is a non-invasive technique that visualizes the gallbladder, biliary tree and pancreatic duct and also provides information about surrounding structures. This study was done to correlate the MRCP findings with post-operative result and thereby demonstrate the specificity, sensitivity and efficacy of MRCP as an accurate investigatory tool for biliary obstruction. Total of fifty (50) patients of clinically diagnosed obstructive jaundice were studied from March 2017 to August 2017 in the Department of Radiology and Imaging, Combined Military Hospital, Dhaka, Bangladesh. In all these cases, USG was the initial screening investigation followed by MRCP. Cause and level of obstruction were evaluated using MRCP findings. MRCP results were correlated with surgical findings and few cases also with direct ERCP findings. Statistical analysis was done to see the sensitivity, specificity, accuracy, positive and negative predictive values of MRCP in diagnosis of biliary obstruction. In this study, USG detected level of obstruction in 56% (28 out of 50) cases. USG could detect causes of obstruction in 100% (02 out of 02) cases of choledocal cyst and 66.67% (02 out of 03) benign stricture, 60% (03 out of 05) cases of periampullary carcinoma, 57.70% (06 out of 14) cases of choledocholithiasis, and 42.86% (15 out of 26) cases of cholangiocarcinoma. On the other hand, MRCP detected level of obstruction in 98% (49 out of 50) cases. MRCP could detect causes of obstruction in 100% cases of cholangiocarcinoma, choledocholithiasis, benign stricture and choledocal cyst and 80% (04 out of 05) cases of periampullary carcinoma. In this study, ERCP could detect causes of obstruction in 32 cases of choledocholithiasis and benign stricture, but in case of cholangiocarcinoma ERCP was failed in 3 cases. In this study, for detection of cause of obstruction, ERCP had the highest sensitivity (97.79%); followed by MRCP (96.65%) and USG (60.25%). The overall diagnostic accuracy for detection of cause of obstruction was the highest for ERCP (95.50%); followed by MRCP (94.50%) and USG (64.50%). MRCP can be done in a short duration and is a noninvasive diagnostic modality compared to ERCP. MRCP needs to be advocated as a viable and non-invasive alternative with compararable sensitivity and specificity to ERCP.

Abstract
Very little is known about the malacofauna in district Swat of Khyber Pakhtunkhwa province, situated in the Northern part of Pakistan. The Swat valley possesses a variety of suitable environmental conditions, providing different types of habitats for both flora and fauna. Taken into consideration these points, the present study was conducted to explore the terrestrial snails diversity in agricultural and non-agricultural fields in the lower Swat valley. A total of 417 shells were collected from three sites: Kokarai, Kanju Township, and Deolai. Based on conchological features, three families: Bradybaenidae, Hygromiidae, and Zonitidae were identified using different terrestrial snail keys. In Kokarai and Deolai, shells of members of all the above-mentioned families were found from agricultural fields. In Kanju Township, shells of members of the family Bradybaenidae and Zonitidae were found. From these findings, it was concluded that district Swat possesses a significant malacofauna which was unexplored before and aided more to the existing literature on malacofauna. It also supports the idea that the agroecosystem is rich in species diversity. Further in-depth and extensive study is recommended to be carried out for a detailed taxonomy of the described terrestrial gastropod families.

Abstract
Background Due to the lack of high-quality evidence which has hindered the development of evidence-based guidelines, there is a need to provide general guidance on cranioplasty (CP) following traumatic brain injury (TBI), as well as identify areas of ongoing uncertainty via a consensus-based approach. Methods The international consensus meeting on post-traumatic CP was held during the International Conference on Recent Advances in Neurotraumatology (ICRAN), in Naples, Italy, in June 2018. This meeting was endorsed by the Neurotrauma Committee of the World Federation of Neurosurgical Societies (WFNS), the NIHR Global Health Research Group on Neurotrauma, and several other neurotrauma organizations. Discussions and voting were organized around 5 pre-specified themes: (1) indications and technique, (2) materials, (3) timing, (4) hydrocephalus, and (5) paediatric CP. Results The participants discussed published evidence on each topic and proposed consensus statements, which were subject to ratification using anonymous real-time voting. Statements required an agreement threshold of more than 70% for inclusion in the final recommendations. Conclusions This document is the first set of practical consensus-based clinical recommendations on post-traumatic CP, focusing on timing, materials, complications, and surgical procedures. Future research directions are also presented.

Abstract
BACKGROUND Asylum seekers and refugees (ASRs) often experience poor health in host countries. The United Nations High Commissioner for Refugees (UNHCR) requires hosts to ensure these sanctuary seekers have access to basic health care. AIM To identify barriers and facilitators that affect access to health care by ASRs in Wales. DESIGN & SETTING Participatory research approach using qualitative focus groups across Wales, which hosts 10 000 refugees. METHOD Eight focus groups were undertaken with ASRs, support workers, and volunteers (n = 57). RESULTS Specialist NHS-funded services and grant-aided non-governmental organisations (NGOs) facilitated access to health care, including primary care. Most ASRs understood the role of general practice in providing and coordinating care, but were unaware of out-of-hours services. Reported barriers included: language difficulties, health literacy, unrecognised needs, and the cost of travel to appointments. Participants recognised the importance of mental health, but were disappointed by the state of mental health care. Some feared seeking support for mental health from their GP, and few were aware they had the right to move practice if they were unhappy. Written information about health care was not as accessible to refugees as to asylum seekers (ASs). While some participants read such material before consulting, others struggled to access information when in need. Few participants were aware of health prevention services. Even when they knew about services, such as smoking cessation, these services' difficulty in accommodating ASRs was a barrier. CONCLUSION The main barriers identified were: availability of interpreters; knowledge about entitlements; and access to specialist services.
