Abstract
Kidney Disease (KD), has a high global prevalence and accounts for one of the most prominent causes of morbidity and mortality in the twenty-first century. Despite the advances in our understanding of its pathophysiology, the only available therapy options are dialysis and kidney transplantation. Mesenchymal stem cells (MSCs) have proven to be a viable choice for KD therapy due to their antiapoptotic, immunomodulatory, antioxidative, and pro-angiogenic activities. However, the low engraftment, low survival rate, diminished paracrine ability, and delayed delivery of MSCs are the major causes of the low clinical efficacy. A number of preconditioning regimens are being tested to increase the therapeutic capabilities of MSCs. In this review, we highlight the various strategies to prime MSCs and their protective effects in kidney diseases.

Abstract
Chevon Seekh Kabab is a popular meat product of India. However, due to high protein and moisture content it undergoes quick microbial spoilage and oxidative reactions leading to lower shelf life. The combination of chitosan edible film and cinnamon essential oil (CEO) was chosen to remediate this problem because of its antimicrobial and antioxidative effect. Control and chitosan edible film with CEO coated chevon Seekh Kabab samples were stored at 4 °C. The physicochemical (pH, TBARS, TVBN, moisture, colour), microbiological (APC, psychrophilic, coliform and Staphylococcal count) and sensory attributes were evaluated over a 30 days period. The maximum shelf life of 27 days was observed when 2% chitosan edible film with 0.3% CEO was coated over samples. A reduction in moisture, L* value, a* value and sensory scores along with an increase in pH, TVBN, TBARS, b* value and microbiological parameters were observed during the storage period. Reaction kinetics for the physicochemical and microbiological parameters was also established. The physicochemical, microbiological and sensory parameters were within prescribed limits till spoilage in the treated sample. This investigation may aid researchers working on scaling up of processing and preservation of Seekh Kabab.

Abstract
The manufacturing and characterization of freeform optical surfaces are influenced by their high sensitivity to misalignments. In this work, the computational sampling moiré technique combined with phase extraction is developed for the precise alignment of freeform optics during fabrication and in metrology applications. This novel, to the best of our knowledge, technique achieves near-interferometry-level precision in a simple and compact configuration. This robust technology can be applied to industrial manufacturing platforms (such as diamond turning machines, lithography, and other micro-nano-machining techniques) as well as their metrology equipment. In a demonstration of computational data processing and precision alignment using this method, iterative manufacturing of freeform optical surfaces with a final-form accuracy of about 180 nm was accomplished.

Abstract
Abstract
Aim
In recent years, the GKT School of Medical Education has introduced a new curriculum resulting in a shift from a single surgical block to an integrated approach. After recognising the potential challenges that the lack of standardisation across various hospitals may cause, we created the Surgical Handbook to supplement learning, improve confidence in approaching surgical patients and prepare students for the United Kingdom Foundation Programme (UKFP).
Method
We sought authorisation for the Surgical Handbook from the GKT medical education faculty, assembled a team and conducted further background research. The National Undergraduate Curriculum by the Royal College of Surgeons of England was an excellent resource in the design of the Surgical Handbook. The handbook underwent multiple cycles of review by senior medical education faculty before its final digital and physical distribution for students.
Results
The Surgical Handbook has resulted in a sustained positive impact on surgical education for GKT students, with feedback highlighting it as an excellent additional resource for placements, exams, and the Foundation Programme.
Conclusions
Most doctors in the United Kingdom will undertake a surgical rotation as part of the Foundation Programme. Preparation for this role is essential and linked to the quality of undergraduate surgical education. Nevertheless, the importance of surgical teaching within the undergraduate curriculum remains a topic of debate. Our Surgical Handbook addresses this issue, and we are in the process of collaborating with other medical schools across the United Kingdom and beyond.

Abstract
In this study, four water quality parameters were reviewed at 14 stations of river Ganga in pre-, during and post-lockdown and these parameters were modeled by using different machine learning algorithms. Various mathematical models were used for the computation of water quality parameters in pre-, during and post- lockdown period by using Central Pollution Control Board real-time data. Lockdown resulted in the reduction of Biochemical Oxygen Demand ranging from 55 to 92% with increased concentration of dissolved oxygen at few stations. pH was in range of 6.5-8.5 of during lockdown. Total coliform count declined during lockdown period at some stations. The modeling of oxygen saturation deficit showed supremacy of Thomas Mueller model (R2 = 0.75) during lockdown over Streeter Phelps (R2 = 0.57). Polynomial regression and Newton's Divided Difference model predicted possible values of water quality parameters till 30th June, 2020 and 07th August, 2020, respectively. It was found that predicted and real values were close to each other. Genetic algorithm was used to optimize hyperparameters of algorithms like Support Vector Regression and Radical Basis Function Neural Network, which were then employed for prediction of all examined water quality metrics. Computed values from ANN model were found close to the experimental ones (R2 = 1). Support Vector Regression-Genetic Algorithm Hybrid proved to be very effective for accurate prediction of pH, Biochemical Oxygen Demand, Dissolved Oxygen and Total coliform count during lockdown.

Abstract
Abstract
Study question
Does the approach of sperm preparation technique plays any role in sperm DNA Integrity
Summary answer
Outcome of the semen sample is directly proportional to the choice of preparation technique. Microfluidics improves sperm selection and results in better sperm DNA integrity
What is known already
Microfluidic systems are promising tools for fluid manipulation that can noninvasively separate motile sperm with higher hydrodynamics profile from the lower ones. It also enables to manipulate micro swimmers as compared to the traditional methods that to without centrifugation .As it is already known that Semen analysis and preparation is one of the most important aspects in andrology and microfluidics can improve sperm analysis and selection, therefore increasing the ART success rates
Study design, size, duration
Comparative study from July 2019 to Dec 2021 in IVF unit of IKDRC Hospital .A total number of 900 patients were enrolled in the study and were randomized by using computer generated list then divided into two groups, Group A contains 460 samples and Group B having 440 samples.
Participants/materials, setting, methods
Group A (n = 460) sample was prepared by using Microfluidic sperm Sorting technique and Group B (n = 440) sample was prepared by conventional Swim up technique. Samples were analyzed according to WHO 2010 laboratory manual for examination and processing of human sperm, including all normozoospermic samples. Primary outcomes of the study was DNA Fragmentation index (DFI) and it was evaluated by using sperm chromatin dispersion (SCD) test and secondary outcomes was Progressive motility .
Main results and the role of chance
DNA fragmentation index is significantly lower in group A where Microfluidic Sperm Sorting technique (MFSS )is used than in group B where conventional swim up technique is use (10.06% vs 34.2%, p<0.0001) significant values implies that DNA integrity is better in group A than in group B and progressive motility was also found to be significantly higher in group A as compared to group B (57.6%vs16.9%, p <0.001).
Limitations, reasons for caution
As sample size was smaller, larger randomized control studies are needed to strengthen these results and all normal samples were used for the analysis and preparation , abnormal parameters were not involved .
Wider implications of the findings
According to our study the samples prepared by Microfluidic technique have higher DNA integrity than samples prepared by Swim up technique. Lower DNA Fragmentation index in microfluidics outcome indicates lower DNA damage. Choice of technique for the preparation of semen sample also plays a key role in better sperm selection.

Abstract
Superfine optical components are necessary for advanced engineering applications such as x-ray optics, high-power lasers, lithography, synchrotron optics, laser-based sensors, etc. Fabrication of such superfine surfaces is one of the major challenges for optical and semiconductor industries. This research focuses on the development of a magnetic nanoparticle-based nanoabrasive for superfine optical polishing. The superparamagnetic iron oxide nanoparticle (SPION)-based nanoabrasive is synthesized via a hydrothermal route by employing cost-effective precursors. Detailed characterizations of the prepared nanoabrasive are presented. Transmission electron microscopy results confirm the irregular cubic and spherical shaped morphology of the SPION nanoabrasive along with particle size distribution varying from 10-60 nm, enabling the homogenous cutting effect of the aqueous slurry for polishing. Furthermore, the high surface area and pore size are determined by Brunauer-Emmet-Teller analysis and found to be 30.98m2/g and 6.13 nm, respectively, providing homogenous distribution of the nanoabrasive on the surface of a BK7 substrate for material removal. Application of the developed SPION abrasive is demonstrated for superfinish optical polishing on a BK7 optical disc. The experimental polishing results show superfine surface finishing with an average roughness value of 3.5 Å. The superparamagnetic property of the developed nanoabrasive is confirmed by alternative gradient magnetometry, and it helps in recovering the used nanoabrasive after polishing. Moreover, the polishing performance of the SPION nanoabrasives is compared with a cerium nanoabrasive, which is also synthesized in this study.

Background
Acute myocardial infarction (AMI) can have considerable morbidity and devastating socioeconomic and psychological consequences in young adults. Previous studies reveal that the decline in mortality in AMI has mainly been in the older population while being comparatively less significant in younger patients. This study compares young adults (18 to 44 years) hospitalized with AMI across two nationwide cohorts, 2007 and 2017, in the United States (US). It examines the burden of AMI hospitalizations, the prevalence of comorbidities, and in-hospital outcomes in young adults a decade apart. It highlights the rise in AMI hospitalizations, lack of decrease in mortality, sex-based and racial disparities, the surge in post-MI complications, and the decline in reperfusion interventions in young AMI patients over a decade.
Purpose
Coronary heart disease prevalence is challenging to ascertain in younger adults because of limited data and frequent silent clinical presentations. AMI and its complications can cause considerable morbidity, psychological trauma, and socioeconomic burden in the young.
Methods
We identified hospitalizations for AMI in young adults in 2007 and 2017 using the weighted data from the National Inpatient Sample (NIS), which covers 20% of stratified data of all non-federal community hospitals in the US. We compared the following data between the two cohorts: admission rates, sociodemographic features, in-hospital morbidity, complications, mortality, rate of coronary interventions, and healthcare utilization between the two cohorts. We used Pearson’s Chi-square test and Mann-Whitney U test to compare categorical and continuous variables, respectively. We also applied multivariable regression analyses to assess and compare the risk of cardiovascular complications and in-hospital mortality while controlling for confounders, including age, sex, race, median household income quartile, primary insurance enrolment, and pre-existing comorbidities.
Results
AMI’s incidence was higher in males in both the cohorts, although with a decline (71.1% vs 66.1%), whereas it rose from 28.9% to 33.9% in females. Hypertension (47.8% vs 60.7%), smoking (49.7% vs 55.8%), obesity (14.8% vs 26.8%), and diabetes mellitus (22.0% vs 25.6%) increased in the 2017 cohort (Table 1). We found no significant difference in all-cause mortality (aOR = 1.01 (0.93-1.10), p=0.749). Post-AMI complications, cardiogenic shock (aOR = 1.16 (1.06-1.27), p=0.001), and fatal arrhythmias increased. Reperfusion interventions decreased in the 2017 cohort (PCI; aOR=0.95 (0.91-0.98), p<0.001; CABG; aOR=0.66 (0.61-0.71), p<0.001) (Table 2).
Conclusion
Our study highlights the rise in AMI hospitalizations, plateauing of mortality, gender disparity, the surge in post-MI complications, and a reassuring decline in the requirement of reperfusion interventions in young AMI patients over a decade.

Background
Obesity in the young population is emerging as a challenging health concern. Though there is a rising prevalence of obesity and its potential association with demand ischemia-related myocardial infarction, data remains non-existent to evaluate the association of obesity or higher body mass index (BMI) with type 2 myocardial infarction (T2MI). We aim to identify the frequency, risk and predictors of T2MI in young hospitalized obese patients compared to non-obese patients in this population-based study.
Methods
We used National Inpatient Sample (2018, ICD-10 codes) to identify T2MI in young (18-44 years) hospitalized patients. Obesity was identified from comorbidities or using diagnostic codes for BMI>30 kg/m2. We performed multivariable regression analysis for the primary outcome of odds of T2MI in young obese patients compared to non-obese patients. The frequency of T2MI was compared between obese vs non-obese patients in overall and subgroup populations. Sociodemographic characteristics and comorbidities in T2MI-obese vs. T2MI-non-obese cohorts were also compared. A p<0.05 was considered a threshold for statistical significance.
Results
Out of 1,268,255 young hospitalized patients with obesity, 555 had T2MI. T2MI was significantly higher in young obese than non-obese (44 T2MI/100000 hospitalizations in young obese patients vs. 17 T2MI/100000 hospitalizations in young non-obese patients, overall 0.04% in obese vs. 0.02% in non-obese, p<0.001). Multivariate analysis revealed higher odds of T2MI in obese than nonobese when adjusted for demographics (aOR 2.65, 95% CI:2.42-2.90, p<0.001) and social demographics with comorbidities (aOR 1.60, 95% CI:1.24-2.07, p<0.001). In young obese, higher risk was found with advancing age (OR 1.07, 95% CI 1.03-1.11, p=0.001), in males than females (aOR 2.70, p<0.001), and blacks (aOR 2.22, p=0.011) and Native Americans (OR 3.91, 95% CI: 1.13-13.49, p=0.011) vs whites. Comorbidities including chronic obstructive pulmonary disease (OR 1.86), chronic kidney disease (CKD, OR 2.36), rheumatoid arthritis/collagen vascular disease (RA/CVD, OR 3.04) Iin young obese patients independently increased the risk of T2MI hospitalizations [Table 1]. The T2MI-obese cohort had a significantly higher rate of hyperlipidemia, hypertension, diabetes, COPD, and prior history of MI and TIA/stroke compared to the T2MI-nonobese cohort [Table 2].
Conclusion
This nationwide analysis revealed a significantly higher risk of T2MI in young obese patients compared to nonobese after excluding patients with concomitant diagnoses of T1MI. Males, blacks compared to females and whites, and comorbidities including COPD, CKD and RA/CVD predicted a higher risk of T2MI in young obese patients. Future studies are warranted to evaluate the role of higher body mass index in myocardial oxygen demand-supply mismatch and short-term/long-term risk and outcomes of T2MI.

Background
Type 2 myocardial infarction (T2MI), due to a mismatch between myocardial oxygen demand and supply, is being increasingly recognized with improved diagnostics. The upsetting concern of developing T2MI in patients with prior revascularized occlusive acute myocardial infarction (AMI) or type 1 MI (T1MI) makes it crucial to define the clinical profile and outcomes of T2MI in revascularized patients of ACS.
Purpose
To determine the risk and prognosis of T2MI in patients who had previously had coronary revascularization (PCI or CABG)
Methods
We used the National Inpatient Sample (2018) dataset from the United States to identify T2MI adult hospitalizations using ICD-10 codes and define our study arm as T2MI excluding secondary T1MI diagnoses but having prior revascularized (with percutaneous coronary intervention or coronary artery bypass grafting) AMI. We then compared demographics and comorbidities in T2MI cohort with vs without personal history of revascularized AMI. We used multivariate analysis to study the odds of T2MI hospitalizations with prior revascularized AMI and in-hospital outcomes (all-cause mortality, cardiogenic shock and resource utilization) adjusting for confounders.
Results
There were 33155 T2MI adult hospitalizations after excluding AMI (median age 71 years, 50.6% male, 67.3% white); 1435 (4.3%) had previously revascularized AMI. T2MI in the study arm had higher chances of hospitalization with prior revascularized AMI when adjusted for socio-demographics (aOR 6.92, 95% CI:6.50-7.36, p<0.001) and socio-demographics with comorbidities (aOR 5.70, 95%CI: 5.48-5.94, p<0.001) (Table 1). Study arm often had elderly (≥65 years old, 78.4% vs 65.8%), male (66.6% vs 49.9%), white (76.7% vs 66.9%), upper socio-economic class (20.2 vs 16.8%), patients who were often admitted to non-electively (99.3 vs 97.1%) and to rural (10.5 vs 9.3%) hospitalizations compared to control arm. The study arm had a significantly higher prevalence of diabetes mellitus, hyperlipidemia, peripheral vascular disease, chronic obstructive pulmonary disease, renal failure, deficiency anemias, prior TIA/stroke, depression and smoking. T2MI cohort with prior revascularized AMI did not show any significant association with in-hospital all-cause mortality (1.7 vs 3.0%, aOR 0.49, 95%CI 0.18-1.34, p=0.164) and cardiogenic shock (1.7% vs 2.1%, p=0.399) however, had lower hospital expenditure (median USD 31273 vs 36567) and fewer transfers to other facilities (19.5 vs 22.1%) than those without prior revascularized AMI (Table 2).
Conclusion
Population-based analysis of this nationally representative sample revealed up to six times higher risk of developing T2MI in patients with prior history of AMI (revascularized) but without any significant impact on all-cause in-hospital mortality or cardiogenic shock. Future studies are warranted to assess the short-term/long-term outcomes of T2MI in high risk patient population with previously revascularized AMI.

Abstract
BACKGROUND As advocated by WHO in "Closing the Health Gap in a Generation", dramatic differences in child health are closely linked to degrees of social disadvantage, both within and between communities. Nevertheless, research has not examined whether child health inequalities include, but are not confined to, worse acute respiratory infection (ARI) symptoms among the socioeconomic disadvantaged in Pakistan. In addition to such disadvantages as the child's gender, maternal education, and household poverty, the present study also examined the linkages between the community environment and ARI symptoms among Pakistan children under five. Furthermore, we have assessed gender contingencies related to the aforementioned associations. METHODS Using data from the nationally representative 2017-2018 Pakistan Demographic and Health Survey, a total of 11,908 surviving preschool age children (0-59 months old) living in 561 communities were analyzed. We employed two-level multilevel logistic regressions to model the relationship between ARI symptoms and individual-level and community-level social factors. RESULTS The social factors at individual and community levels were found to be significantly associated with an increased risk of the child suffering from ARI symptoms. A particularly higher risk was observed among girls who resided in urban areas (AOR = 1.42; p<0.01) and who had a birth order of three or greater. DISCUSSIONS Our results underscore the need for socioeconomic interventions in Pakistan that are targeted at densely populated households and communities within urban areas, with a particular emphasis on out-migration, in order to improve unequal economic underdevelopment. This could be done by targeting improvements in socio-economic structures, including maternal education.

Abstract
OBJECTIVES Studies that examined the growth during late childhood and early adolescence beyond 8 years of age are very limited. Further, most studies have used dichotomized classification of stunting, thereby limiting the understanding of moderate stunting in childhood growth trajectory. We aimed to examine the course of stunting from childhood to adolescence by undertaking robust analyses of the Young Lives Survey (YLS) longitudinal data from India using multilevel categorization of stunting. STUDY DESIGN Retrospective cohort analysis was undertaken from YLS in India among 1827 children from the younger cohort born in 2001-02 with complete follow-up data in all five rounds of YLS collected in 2002, 2006, 2009, 2013, and 2016. METHODS A three-state multistate Markov model (not stunted, moderate, severe) was performed to estimate annual transition probabilities, mean sojourn-time, and transition-specific risk factors. RESULTS Between Round-one and Round-five, cross-sectional prevalence of severe stunting decreased from 10.4% (95% confidence interval [CI]: 7.8%, 13.7%) to 5.3% (95% CI: 3.8%, 7.3%), while moderate stunting increased from 19.9% (95% CI: 16.3%,23.9%) to 21.7% (95% CI: 18.4%, 24.9%). Mean Sojourn time estimation indicated a relatively concise state for moderate stunting. The stunting trajectory had shown gender differential where more faltering to severe stunting and lower recovery to the normal state was observed among girls between 8 and 12 years and among boys between 12 and 15 years. Compared with boys, girls had 40% excess likelihood (Hazard Ratio: 1.40; 95% CI 1.00 to 1.95) for moderate-to-severe stunting transition and also had 19% excess likelihood (Hazard Ratio: 1.19; 95% CI 1.01 to 1.40) of favorable transition (moderate-to-non-stunted). CONCLUSIONS The transition trajectory highlights preadolescence, especially among girls, as an additional window of opportunity to ensure better nutrition in adolescent life. With a fifth of adolescents living in India, study findings call for coordinated, multisectoral, age-appropriate, and gender-responsive approach to take India closer to meeting SDG-2.

Abstract
Abstract
Study question
Does semen hyper viscosity effects blastocyst formation rate
Summary answer
Hyper viscosity of semen sample later results in poor blastocyst formation rate and lower implantation rate.
What is known already
Normal range of semen hyper viscosity ranges between 12–29%.Highly viscous semen samples impairs the physical and chemical characteristics of seminal fluid and due to which seminal oxidative damage increases which further increases the ROS and reduces the sperm motility there are some factors that can affect the seminal viscosity out of which one is Male accessory gland infection, Hypo function of prostate seminal vesicles and varicoceles. SHV create hindrance in semen preparation.
Study design, size, duration
Retrospective study was conducted from June 2019 to Oct 2020 at IVF unit IKDRC hospital.
Participants/materials, setting, methods
142 patients were enrolled from June 2019 to Oct 2020 in IVF unit IKDRC hospital and divided into two groups. Group A (n = 83) patients with hyper semen viscosity and Group B (n = 69) patients with normal semen viscosity, inclusion and exclusion criteria’s were same for both the groups, only patient with normozoospermia were taken. Semen analysis was done by using WHO manual 2010.
Main results and the role of chance
In group A with hyper semen viscosity fertilization rate was (49.2% vs. 70% p = <0.001) vs in group B with normal semen viscosity which is significantly higher in group B, Blastocyst formation rate ( 18.4% vs 35% p = <0.01) and implantation rate (9.4% vs 20% p = <0.005) both are significantly higher in group B . Which implies fertilization rate , blastocyst formation rate and implantation rate is significantly lower in patients with semen hyper viscosity.
Limitations, reasons for caution
Larger randomized control studies are needed to strengthen these results.
Wider implications of the findings: Our study demonstrates that patients having higher semen viscosity have poor blastocyst formation rate and implantation rate due to oxidative stress.

Abstract
Abstract
Study question
Does sperm vitrification technique helps in increasing sperm survival and low DNA fragmentation index post warming.
Summary answer
Sperm vitrification protocol results in better motility, high progression and low DNA fragmentation index as compared to slow freezing.
What is known already
Cryopreservation is ceasing and resuming the cell metabolism, which can be achieved by different techniques like slow freezing and vitrification .Vitrification allows solidification of the cells and extracellular milieu into a glass like state without formation of ice which protects intracellular and extracellular ice formation, and further helps in avoiding different types of cryo-injuries and cellular damage. Study design, size, duration: Comparative study from July 2019 to Oct 2020 in IVF unit of IKDRC Hospital. Two hundred and ten patients were randomized by computer generated list and divided into two groups. Group 1 (n = 110) samples cryopreserved by vitrification and Group 2 (n = 100) samples cryopreserved by conventional slow freezing.
Participants/materials, setting, methods
Semen sample were analyzed by WHO 2010 laboratory manual, including all normozoospermic samples , other abnormal samples were excluded from the study . Method of semen preparation before cryopreservation is similar for both the groups, double density gradient method of preparation was used . Semen sample with high viscosity, hypo and hyper-spermia were also excluded. Similar cryovials of 2ml volume were used for both groups.
Main results and the role of chance
In group 1 where samples were cryopreserved by vitrification sperm motility was (54.3% vs 49.2%)vs in group 2 where samples were cryopreserved by slow freezing , non- significant difference were observed , but progressive motility was significantly higher in group 1 as compared to group 2 (36.8%vs17.9%) and DNA fragmentation index is significantly lower in group 1 vitrification than in group 2slow freezing ( 9.7% vs 20%).
Limitations, reasons for caution
Technical proficiency of the operator to avoid human errors and still larger randomized control studies are needed to strengthen these results
Wider implications of the findings: Our study demonstrates that vitrification is better than slow freezing of human sperm, improved survival rates with high progression were found with vitrification and low DNA fragmentation index were also observed in samples cryopreserved with vitrification protocol.

Abstract
Before encapsulation of spent nuclear fuel in a geological repository, the fuels need to be verified for safeguards purposes. This requirement applies to all spent fuel assemblies, including those with properties or designs that are especially challenging to verify. One such example are quivers, a new type of containers used to hold damaged spent fuel rods. After placing damaged rods inside the quivers, they are sealed with a thick lid and the water is removed. The lid is thick enough to significantly reduce the amount of the gamma radiation penetrating through it, which can make safeguards verification from the top using gamma techniques difficult. Considering that the number of quivers at storage facilities is foreseen to increase in near future, studying the feasibility of verification is timely.
In this paper we make a feasibility study related to safeguards verification of quivers, aimed at investigating the gamma and neutron radiation field around a quiver designed by Westinghouse AB and filled with PWR fuel rods irradiated at the Swedish Ringhals site. A simplified geometry of the quiver and the detailed operational history of each rod are provided by Westinghouse and the reactor operator, respectively.
The nuclide inventory of the rods placed in the quiver and the emission source terms are calculated with ORIGEN-ARP. The radiation transport is modeled with the Serpent2 Monte Carlo code. The first objective is to assess the capability of the spent fuel attribute tester (SFAT) to verify the content for nuclear safeguards purposes. The results show that the thick quiver lid attenuates the gamma radiation, thereby making gamma radiation based verification from above the quiver difficult.

Abstract
Although advances in knowledge and technology have improved outcomes in surgical cardiac patients over the last decade, complications following cardiac operations still remain to be potentially fatal. Gastrointestinal complications, in particular, tend to have high rates of reintervention and mortality following cardiac surgery, with ischemia and hemorrhage being two of the commonest underlying causes. The intention of this review is to identify which risk factors play important roles in predisposing patients to such complications and to gain better insight into the pathogenesis of the sequelae. Furthermore, strategies for prevention have been discussed to educate and increase awareness of how adverse cardiac surgical outcomes can be minimized.

Abstract
Abstract
Background
An ideal strategy for radiofrequency ablation (RFA) of atrial fibrillation (AF) in the left atrium should be efficient enough to achieve transmural lesions in left atrium with no or minimal collateral tissue damage. Resistive heating of high power short duration (HPSD) RFA has been found to result in lesions larger in width but lesser in depth compared to lower power longer duration (LPLD) RFA in some experimental studies.
Purpose
This meta-analysis was performed to compare procedural, short-term and long-term outcomes of HPSD versus LPLD RFA of AF.
Methods
PubMed, Embase and Cochrane databases were systematically reviewed. Five observational studies meeting criteria were included in the meta-analysis. All the studies scored six or more points in the New-castle Ottawa scale. There were considerable variations in the ablation strategies across the studies. However, radiofrequency power more than 40W was considered as high power. Hypergeometric model with exact likelihood function was utilized for statistical analysis.
Results
Baseline parameters and ablation details have been depicted in Table 1. 740 patients with HPSD and 287 patients with LPLD ablation strategies, were followed up from 6 to 30 months. Total procedural time (P value <0.0001) and ablation time (P value <0.0001) were significantly lower in the HPSD group than LPLD group. However, the fluoroscopy time was similar (P value = 0.09) in both the groups (Table 2). There were no occurrences of atrio-esophageal fistula or pulmonary venous stenosis in any of the studies. Cardiac tamponade (P value = 0.56), stroke (P value = 0.70) and AF recurrences (P value = 0.81), were similar in both groups (Table 2).
Conclusion
Newer HPSD and conventional LPLD RFA, both the strategies are very safe procedure for treatment of RFA with low to no procedural complications. AF recurrence rates were reasonably high irrespective of ablation strategies, however, no strategy scored statistically better over the other one. Large randomized multi-centric studies with long-term follow up are needed to test the theoretical advantage of HPSD ablation over the traditional ablation strategy of AF.

Abstract
In the present research, a composite layer of TiO₂-TiC-NbO-NbC was coated on the Ti-64 alloy using two different methods (i.e., the electric discharge coating (EDC) and electric discharge machining processes) while the Nb powder were mixed in dielectric fluid. The effect produced on the machined surfaces by both processes was reported. The influence of Nb-concentration along with the EDC key parameters (Ip and Ton) on the coated surface integrity such as surface topography, micro-cracks, coating layer thickness, coating deposition, micro-hardness has been evaluated as well. It has been noticed that in the EDC process the high peak current and high Nb-powder concentration allow improvement in the material migration, and a crack-free thick layer (215 μm) on the workpiece surface is deposited. The presence of various oxides and carbides on the coated surface further enhanced the mechanical properties, especially, the wear resistance, corrosion resistance and bioactivity. The surface hardness of the coated layer is increased from 365 HV to 1465 HV. Furthermore, the coated layer reveals a higher adhesion strength (~118 N), which permits to enhance the wear resistance of the Ti-64 alloy. This proposed technology allows modification of the mechanical properties and surface characteristics according to an orthopedic implant's requirements.

Abstract
OBJECTIVES: Today, both surgical and percutaneous techniques are available for pulmonary valve implantation in patients with right ventricle outflow tract obstruction or insufficiency. In this controlled, non-randomized study the hospital costs per patient of the two treatment options were identified and compared. METHODS: During the period of June 2011 until October 2014 cost data in 20 patients treated with the percutaneous technique and 14 patients treated with open surgery were consecutively included. Two methods for cost analysis were used, a retrospective average cost estimate (overhead costs) and a direct prospective detailed cost acquisition related to each individual patient (patient-specific costs). RESULTS: The equipment cost, particularly the stents and valve itself was by far the main cost-driving factor in the percutaneous pulmonary valve group, representing 96% of the direct costs, whereas in the open surgery group the main costs derived from the postoperative care and particularly the stay in the intensive care department. The device-related cost in this group represented 13.5% of the direct costs. Length-of-stay-related costs in the percutaneous group were mean $3885 (1618) and mean $17 848 (5060) in the open surgery group. The difference in postoperative stay between the groups was statistically significant (P≤ 0.001). CONCLUSIONS: Given the high postoperative cost in open surgery, the percutaneous procedure could be cost saving even with a device cost of more than five times the cost of the surgical device.

Abstract
The proportion of tuberculosis (TB) patients tested for the human immunodeficiency virus (HIV) in the state of Ra-jasthan, India, is limited by the availability of HIV testing facilities. Rajasthan implemented a policy of initiating TB-HIV diagnosis at all health institutions in July 2013. The number of TB diagnostic facilities increased from 33 to 63 in Banswara District and from 22 to 68 in Jhunjhunu District, while the number of HIV testing facilities in these districts increased from 1 to 53 and from 10 to 81, respectively, after the policy implementation. The proportion of TB patients tested for HIV increased by respectively 27% and 19%.

Abstract
Islet transplantation is a minimally invasive β-cell replacement strategy. Islet transplantation is a reimbursed treatment in Norway. Here, we summarize the cost and clinical outcome of 31 islet transplantations performed at Oslo University Hospital (OUS) from January 2010 to June 2015. Patients were retrospectively divided into three groups. Thirteen patients received either one or two islet transplantation alone (ITA), while five patients received islet transplantation after previous solid organ transplantation. For the group receiving 2 ITA, Kaplan-Meier estimates show an insulin independence of 20% more than 4 years after their last transplantation. An estimated 70% maintain at least partial graft function, defined as fasting C-peptide >0.1 nmol L-1 , and 47% maintain a HbA1c below 6.5% or 2 percent points lower than before ITA. For all groups combined, we estimate that 44% of the patients have a 50% reduction in insulin requirement 4 years after the initial islet transplantation. The average cost for an islet transplantation procedure was 347 297±60 588 NOK, or 35 424±6182 EUR, of which isolation expenses represent 34%. We hereby add to the common pool of growing experience with islet transplantation and also describe the cost of the treatment at our center.

Abstract
Mycobacterium abscessus is an unusual cause of infection in immunocompetent patients. The intrinsic and acquired resistance of this organism to multiple antibiotics is a major issue in planning treatment regimens. We report a case of M. abscessus endocarditis of the native aortic valve in an immunocompetent patient following coronary angiography with a fatal outcome. The case highlights an unfortunate intervention – related nosocomial infection and the difficulties in chemotherapeutic options for this organism, particularly in the presence of renal failure.

Abstract
OBJECTIVES Growing number of patients with terminal heart failure and a shortage of heart donors have increased use of short- and long-term mechanical circulatory support (MCS). Few studies have analyzed survival rates and healthcare costs for heart transplantation (HTx), with or without extracorporeal membrane oxygenation (ECMO) and left ventricular assist device (LVAD). DESIGN In a retrospective, single-center study, data were analyzed from patients listed for HTx who died on the waiting list (DWL, n = 12), underwent HTx (n = 206), had ECMO as bridge to HTx (ECHTx, n = 15), or received LVAD treatment, either isolated (LVAD, n = 19) or bridging to HTx (LVADHTx, n = 26) during 2005-2012. Survival and hospital costs were assessed. RESULTS One- and five-year survival rates were 96% and 83% for the LVADHTx group, 92% and 81% for HTx, 70% and 70% for ECHTx, 48% and 36% for LVAD and 0% for the DWL group (overall survival, p < 0.001). Total hospital cost at one year was $102,101 ± 202,604 for DWL, $151,685 ± 86,892 for HTx, $292,078 ± 101,915 for ECHTx, $427,337 ± 365,154 for LVAD, and $600,897 ± 198,109 for LVADHTx. CONCLUSION The LVADHTx and HTx groups showed excellent one- and five-year survival. The combined group of DWL and HTx patients had similar survival to the combined groups of MCS, but use of LVAD pre-transplant quadrupled the cost.

Abstract
The present study, evaluates the antioxidative potential of two synbiotic dairy products viz. synbiotic lassi with honey and whey based synbiotic drink with inulin and orange juice, along with their physicochemical and microbiological activity during storage period. Antioxidative potential of raw ingredients and probiotic cultures used to prepare synbiotic products was also evaluated. Synbiotic lassi with honey was prepared using Streptococcus thermophilus MTCC 5460 (MD2) and Lactobacillus helveticus MTCC 5463 (V3) as probiotics and honey as prebiotic. For preparation of whey based synbiotic drink, Lactobacillus helveticus MTCC 5463 and inulin were used as probiotic and prebiotic, respectively and orange juice was also incorporated. Titratable acidity and pH of both synbiotic products followed a similar pattern of increase or decrease during storage. Furthermore, no major changes were observed in viability of probiotic cultures under storage conditions adapted. The hydroxyl radical scavenging activity of synbiotic lassi with honey was found to significantly decrease from 107.76 to 79.41 % at the end of storage whereas, the activity of whey based synbiotic drink was 100.32 % which declined sharply to 79.21 % on 7th day but further increased to 102.59 % on 14th day. The DPPH (α, α-Diphenyl-β-Picrylhydrazyl) radical scavenging activity of freshly prepared synbiotic lassi with honey was 28.43 % which decreased to 23.03 % on 7th day while for whey based synbiotic drink decreased from 26.85 % (0 day) to 17.12 % (7th day) and continued to decline. Moreover, probiotic strains used for synbiotic preparation also demonstrated good antioxidative activity.

Abstract
BACKGROUND Nevirapine is a very potent antiretroviral drug frequently used in the management of Human Immunodeficiency Virus (HIV). Opportunistic pathologies in HIV/AIDS patients include gastric ulcer and gastrointestinal haemorrhage. Hence, the impact of nevirapine on induced gastric ulcer was studied using Wistar rats. METHODS Anti-ulcer activity of nevirapine was evaluated using cold restraint stress-induced, ethanol-induced and pylorus ligation-induced gastric ulcer models for acute ulceration; and acetic acid-induced ulcer model for the chronic ulceration in Wistar rats. RESULTS Nevirapine (9 mg/kg, 18 mg/kg and 36 mg/kg) showed significant (P < 0.05) reduction in ulcer severity score and ulcer index as compared to the control in the models,.with corresponding increase in percentage inhibition. Histopathological studies showed that nevirapine has a positive effect on the healing of gastric ulcer in the groups treated with the nevirapine compared with the control. The induced ulcers healed up in all the groups administered with nevirapine compared to what was found in the omeprazole group where manifestations of ulcer like inflammatory cells infiltration is still present. CONCLUSION Nevirapine may possess highly therapeutic effect in the treatment and prevention of gastrointestinal complications that might come with the presence of HIV virus in patients.

Abstract
Psychosocial factors among overweight, obese, and morbidly obese women in Delhi, India were examined. A follow-up survey was conducted of 325 ever-married women aged 20-54 years, systematically selected from 1998-99 National Family Health Survey samples, who were re-interviewed after 4 years in 2003. Information on day-to-day problems, body image dissatisfaction, sexual dissatisfaction, and stigma and discrimination were collected and anthropometric measurements were obtained from women to compute their current body mass index. Three out of four overweight women (BMI between 25 and 29.9 kg/m(2)) were not happy with their body image, compared to four out of five obese women (BMI of 30 kg/m(2) or greater), and almost all (95 percent) morbidly obese women (BMI of 35 kg/m(2) or greater) (p < .0001). It was found that morbidly obese and obese women were five times (adjusted odds ratio [aOR] 5.29, 95% confidence interval [CI] 2.02-13.81, p < .001) and two times (aOR 2.30, 95% CI 1.20-4.42, p < .001), respectively, as likely to report day-to-day problems; twelve times (aOR 11.88, 95% CI 2.62-53.87, p < .001) and three times, respectively, as likely (aOR 2.92, 95% CI 1.45-5.88, p = .001) to report dissatisfaction with body image; and nine times (aOR 9.41, 95% CI 2.96-29.94, p < .001) and three times (aOR 2.93, 95% CI 1.03-8.37, p = .001), respectively, as likely to report stigma and discrimination as overweight women.

Abstract
The ACTH receptor, known as the melanocortin-2 receptor (MC2R), plays an important role in regulating and maintaining adrenocortical function. MC2R is a subtype of the melanocortin receptor (MCR) family and has unique characteristics among MCRs. Endogenous ACTH is the only endogenous agonist for MC2R, whereas the melanocortin peptides α-, β-, and γ-melanocyte-stimulating hormone and ACTH are full agonists for all other MCRs. In this study, we examined the molecular basis of MC2R responsible for ligand selectivity using ACTH analogs and MC2R mutagenesis. Our results indicate that substitution of Phe(7) with D-Phe or D-naphthylalanine (D-Nal(2')) in ACTH(1-24) caused a significant decrease in ligand binding affinity and potency. Substitution of Phe(7) with D-Nal(2') in ACTH(1-24) did not switch the ligand from agonist to antagonist at MC2R, which was observed in MC3R and MC4R. Substitution of Phe(7) with D-Phe(7) in ACTH(1-17) resulted in the loss of ligand binding and activity. Molecular analysis of MC2R indicated that only mutation of the third transmembrane domain of MC2R resulted in a decrease in D-Phe ACTH binding affinity and potency. Our results suggest that Phe(7) in ACTH plays an important role in ligand selectivity and that the third transmembrane domain of MC2R is crucial for ACTH selectivity and potency.
