Abstract
India is bestowed with immense cattle biodiversity with 50 registered breeds. However, the majority (59.3%) is yet not characterized. Identification and characterization are the gateways to the management of prized indigenous resources. Present research described a unique cattle population of Jharkhand state, managed under a traditional low-input, low-output system. It was characterized by morphological traits, performance parameters, and management practices. Animals have the characteristic pre-scapular location of the hump. Genetic variation within this population and its differentiation with the six closely distributed cattle breeds were evaluated using FAO recommended microsatellite markers. Jharkhandi cattle have substantial genetic variation based on gene diversity (>0.6) and the average number of alleles per locus (>8). The population did not suffer from a genetic bottleneck in the recent past. Pairwise Nei's genetic distance, phylogenetic relationship, population differentiation, and the correct assignment of all the animals to self group substantiated its separate genetic identity. Since gene flow (Nm = 2.8-7.32) was identified and admixture was indicated by the Bayesian analysis there is a pressing need for scientific management of this population. Results endow authorities with critical information for registering a new Indian cattle breed (Medini) that contributes to the food security, livelihood, and economic sustainability of rural tribal households.

Abstract
BACKGROUND Vaccine hesitancy is a significant global health concern, and mass vaccination is essential in preventing the spread of COVID-19. Undergraduate students need to be prioritized for vaccination as they continue their academic curriculum physically. However, limited research explores vaccine hesitancy and acceptance among undergraduate students in Bangladesh. Therefore, this study evaluated vaccine hesitancy and acceptance among this population. METHOD A web-based cross-sectional study was conducted between May and June 2021 using a structured questionnaire to assess COVID-19 vaccine hesitancy and acceptance among undergraduate students in Bangladesh. The Oxford Covid-19 Vaccine Hesitancy Scale was used to measure vaccine hesitancy. The study used convenient sampling. RESULT Across the country, 334 undergraduate students participated in this study on COVID-19 vaccine acceptance, with a mean age of 22.4 years. Most participants were male and unmarried, most having spent four years at university. 89.52% of participants would accept a COVID-19 vaccine if it were suggested by educational institutions or available, while 4.49% refused to receive the COVID-19 vaccine. Participants showed low levels of vaccine hesitancy, with a mean score of 10.77 on the Oxford COVID-19 Vaccine Hesitancy Scale. Most participants had a positive attitude towards receiving the vaccine, with the majority wanting to get it as soon as it becomes available. No association was found between vaccine acceptance and participants' background characteristics. CONCLUSION Our study found a high level of vaccine acceptance among undergraduate students in Bangladesh, indicating that this group can be vaccinated quickly, significantly accelerating vaccination goals. However, further large-scale studies are recommended among vulnerable groups, including school and college students, to ensure vaccine preparedness.

Abstract
Crinum malabaricum Lekhak & Yadav is a recently discovered and critically endangered aquatic bulbous plant of the family Amaryllidaceae. It gained attention as a wild source of the acetylcholinesterase inhibiting alkaloid 'galanthamine' used to treat Alzheimer and Parkinson diseases. The bulbs of this plant contain the highest amount of galanthamine among Crinum species. In vitro regeneration systems were developed to produce quality uniform plantlets of C. malabaricum. Bright field light microscopy was used to analyse micro-morpho-anatomical developments taking place in the leaves and roots during in vitro, ex vitro and in vivo transitions of plantlets. Leaves and roots of plants raised in vitro possessed a higher degree of microscopic structural anomalies, such as underdeveloped epicuticular wax deposition, immature and non-functional stomata, more aquiferous parenchyma with a reduced lumen. Roots developed in vitro were characterized by extremely large, uneven cortical cells and reduced intercellular spaces. The vascular tissues were under-developed and only primary vascular tissues were observed. As a result of ex vitro acclimation, there was a significant acceleration in the improvement of tissue systems in leaves and roots. Such plantlets can tolerate elevated temperatures and light under in vivo conditions. Thus, the microscopic evaluation of the structural trajectory in different stages of plantlet development provides an understanding of the acclimation process and structural adaptations, which could help enhance survival of in vitro raised plantlets under ex vitro and in vivo conditions.

Abstract
Cauda equina syndrome (CES) is a serious neurologic state in which neurological dysfunction affects the lumbar and sacral nerve roots within the vertebral canal. The nerves of the cauda equine provide the muscles that manage the bladder, bowel and the legs and the dysfunction producing impairment of bladder, bowel or sexual function and perianal or saddle numbness. Identification of CES is not only important to neurosurgeons and spine surgeons, but also to prime care practitioners, emergency room physicians, physiotherapists and allied health care professionals concerned in management of back pain. It is a significant diagnosis from a clinical and medico-legal outlook. Early surgical decompression is endorsed by most authors to best support patient's revival and trim down long term disability. This cross sectional observational study was conducted at Shaheed Suhrawardy Medical College Hospitals, Dhaka, Bangladesh from January 2015 to January 2021 and the aim of this study was to find the predictors and the clinical outcome of cauda equina syndrome after spinal decompression with delayed presentation. Among 680 patients of degenerative disc diseases; 32 cases (4.7%) had CES, those presenting late in course of disease. Time interval between bladder and bowel dysfunction and admission to hospital varied from 2-64 days with mean delay of 15.4 days. The average follow-up was 22.6 months, ranging from 12 to 34 months. There was significant positive correlation (p<0.05) between duration taken for total recovery and delay in surgery and between delayed decompression and a poor outcome. Also there was a clear correlation between the presence of complete perineal anaesthesia and absence of anal wink as both univariate and multivariate predictors of a poor outcome. There was significant association between a slower onset of CES and a favourable outcome. There was no significant correlation found between initial motor function loss, bilateral sciatica and level of the lesions as predictors of a poor outcome.

Abstract
Abstract
Appendicitis involving the appendix stump is a recognised post appendicectomy complication but the same involving the appendiceal tip is rare. Similarly, abdominal wall abscess secondary to retained appendicolith is also infrequently encountered. Our case highlights a rare combination of both complications arising separately.
A 29-year-old man presented with 3 days of generalised malaise and progressively worsening right iliac fossa pain some ten months after a laparoscopic appendicectomy. This had been complicated by residual right iliac fossa inflammation that was treated conservatively and serial scans demonstrated gradually resolving inflammation. He also had well controlled ulcerative colitis.
On examination, he was noted to be pyrexial with a tender fluctuant mass in the right flank. An ultrasound scan demonstrated inflammatory changes in the abdominal wall with no intra-abdominal collections. A diagnostic laparoscopy found an inflamed appendix tip, attached to the residual mesoappendix and embedded in the abdominal wall behind the mid-ascending colon. A completion appendicectomy was performed.
The patient recovered well but returned 4 months later with persistent pain and a fluctuant mass over the right iliac fossa. Radiological investigation revealed an abdominal wall collection containing a calcified appendicolith. The collection was refractory to ultrasound guided drainage and an exploration of the abdominal wall allowed extraction of the appendicolith followed by symptomatic relief.
This case emphasizes the importance of complete excision of the appendix and extraction of debris, which can be challenging when the appendix lies in a retro-colic position.

Abstract
Abstract
Introduction
In the years following myocardial revascularisation with bypass grafts, patients remain at risk for subsequent ischemia as a result of native coronary artery disease progression or development of graft occlusion. Therefore, secondary measures, primarily medical therapy, play an indispensable role in post-operative care. An audit conducted in 2014 identified reduced compliance to prescription of secondary prevention medications. This audit aims to re- evaluate the level of compliance to updated guidelines.
Method
A retrospective case-note review of 100 patients, who underwent CABG (Coronary Artery Bypass-Grafts), was conducted primarily focusing on prescription of secondary prevention drugs at discharge, indications, and contraindications.
Results
99% patients were discharged on anti-platelet agents. However, 12%, discharged on dual anti-platelet agents, did not have any indications for them. 97 % patients were discharged on beta-blocker. Of the 3 defaulters, one had contraindication to beta blockade. 96% patients were discharged on one or more lipid lowering agents and 74% were discharged on ACEi/ARBs. Of the 26% patients discharged without RAAS (Renin Angiotensin Aldosterone System) inhibitor, 9% had no clear indication for it whereas for 7%, it was contraindicated at discharge.
Conclusions
A generalised improvement in compliance rate is noted for secondary prevention medications prescription according to updated guidelines from the previous audit.

Abstract
Abstract
Small intestinal diverticula are rare and possibly acquired secondary to bowel dyskinesia, abnormal peristalsis, or high intraluminal pressures. Enterolith formation and obstruction are a less encountered complication of these diverticula.
An elderly man, with no history of abdominal surgery, presented with 10 days of colicky right iliac fossa pain and recurrent episodes of bilious vomiting. He initially reported diarrhoea but complained of eventual absolute constipation for last 5 days. Physical examination revealed distended abdomen with right-sided tenderness and no mass or faeces on rectal examination. Abdominal CT revealed a 3.5 cm calculus in the distal ileum causing obstruction initially flagged as gallstone ileus. No gallstones or pneumobilia were identified although some intrahepatic duct dilatation was noted. An emergency laparotomy was conducted, where the radiological findings were reinforced, and the calculus was extracted via enterotomy. There were no abnormal communications between gallbladder and intestinal tract. The small bowel traced from duodenojejunal flexure to terminal ileum did not reveal any further calculi or diverticula. FTIR spectrum analysis of the extracted specimen indicated similarities to enterolith. Retrospective analysis of radiological images revealed a possible duodenal diverticulum. The case highlights the diagnostic conundrum and therapeutic challenges of small bowel diverticular enterolith.

Abstract
INTRODUCTION The Enhanced-View Totally Extra Peritoneal Rives-Stoppa (e-TEP-RS) Technique for the repair of large, complex, ventral abdominal hernias has gained popularity especially in overcoming the disadvantages with Intra Peritoneal Onlay Mesh (IPOM) repairs and to enable siting of a large prosthetic mesh in an anatomical plane distinct from the abdominal cavity and its contents. Evolving variations of the original technique have allowed the definitive repair of such defects in a reproducible manner. We present our initial experience of this approach and detailed steps of our native technical modifications in overcoming the challenges in performing this complex and potentially challenging procedure. MATERIALS AND METHODS This is a retrospective review of the clinical data of midline, large, complex, ventral abdominal hernia patients who underwent e-TEP-RS with and without Transversus Abdominis Release (TAR). Patients, with or without Diastasis of Rectus Abdominis Muscle (DRAM) were included. Key outcomes measured were post-operative pain, operative morbidity, readmission, Quality of Life (QoL), hernia recurrence. RESULTS A total of 58 midline, ventral abdominal hernia patients who underwent e-TEP-RS with and without Transversus Abdominis Release (TAR), between March 2018 and December 2019 were studied. Mean defect area was 41.0 ± 28 cm2 and the mean mesh surface area was 473.5 ± 165 cm2. e-TEP-RS was done in 35 cases, e-TEP RS TAR in 15 cases and e-TEP-RS with e-TEP inguinal in 08 cases. There was no intraoperative morbidity. Mean duration of surgery was 156.2 ± 40 min and mean blood loss was 40.5 ± 26 cc. The CCS QoL scores improved from 34.6 (± 2) pre-operatively to 27.2 (± 4) at the end of 6 months. One patient had a supra-umbilical recurrence following bilateral TAR over the superior edge of the mesh. Follow-up ranged from 6 to 22 months, with a mean of 14 months. Major complications (n = 12; 20.7%) were seroma formation and prolonged ileus. CONCLUSION The e-TEP-RS technique for large, complex, midline, ventral abdominal hernias can be used with excellent results and acceptable morbidity. This technique is technically challenging and should be mastered in relatively smaller ventral hernias to achieve good results before attempting it in larger, complex ones.

Abstract
Biofilm formation on medical implants and devices has been a severe concern that results in their impaired performance and life-threatening complications. Thus, development of novel functional coatings for infection prone surfaces with biofilm inhibiting characteristics is of prime significance considering the rapid emergence of multidrug resistant bacteria. Herein we present a novel nanocomposite derived from Graphene Oxide (GO) and a newly developed functional Ionic liquid (IL) obtained through a metathesis reaction between a triarylmethane dye hexamethyl pararosaniline chloride or crystal violet (CV) and sodium dodeceyl sulfate (SDS) to yield [CV][DS] (hexamethyl pararosaniline dodecyl sulfate). This highly biocompatible [CV][DS]-GO nanocomposite exhibit more than four times improved antibacterial activity in comparison to bare GO against both gram negative Escherichia coli (E. coli) and gram positive Staphylococcus aureus (S. aureus). As suggested by XRD, FTIR and UV absorption and SEM results improved activity of [CV][DS]-GO nanocomposite is ascribed to the synergistic effect of reduced nanocomposite sheet thickness, enhanced amphiphilicity imparted by dodecylsulfate (DS), exposed active ArN+ groups of CV and some inherent functionalities of GO. This is also complemented by the ruptured and diffused S. aureus cell walls as observed in bacterial SEM result. In contrast, the nanocomposites of the precursors with GO do not demonstrate any significant antibacterial effect. Coatings developed using GO upon infestation with E. coli revealed significant biofilm formation after 48 and 72 h of incubation while [CV][DS]-GO coated surface demonstrated no colony growth under similar circumstances. Thus, [CV][DS]-GO nanocomposite coatings exhibit excellent resistance to bacterial growth even up to 72 h incubation signifying its bactericidal effect. Therefore, the developed nanocomposite may be considered as one of the improved antibacterial wash resistant coating material for biomedical devices and surfaces susceptible to to biofilm formation.

Abstract
Coronavirus disease 2019 (COVID-19) is the disease caused by the novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Genome sequencing of the virus revealed that it is a new zoonotic virus that might have evolved by jumping from bats to humans with one or more intermediate hosts. The immediate availability of the sequence information in the public domain has accelerated the development of quantitative RT-PCR-based diagnostics. Numerous clinical trials have been prioritized globally for testing new vaccines and treatments against this disease. This review provides a broad insight into different aspects of COVID-19, an introduction to SARS-CoV-2 mitigation strategies and the present status of diagnostics and therapeutics.

Abstract
Abstract
Given the high Neo-natal mortality in the state of Uttar Pradesh, India, an emphasis has been given to community health workers (CHW). CHW provides behavior push to pregnant women for utilizing health services, through the strategies of household contact and messaging. However, the disparity in health outcomes and interaction of CHW is profoundly affected by socio-economic determinants; still, the evidence is limited. This study aims to explore socio-economic inequities in quantity and quality of contacts by the CHW and its differential effect on health service utilization.
Multistage sampling design identified live births in the last 12 months across the 25 highest-risk districts of Uttar Pradesh(n = 3703). Regression models described the relation between household demographics and CHW contact & specific messaging and interactions of demographics and CHW contact & messaging in predicting health service utilization ( > = 4 antenatal care (ANC) visits, Institutional delivery and 100 iron folic acid (IFA) consumption).
No differential likelihood in contact of CHW and specific messaging is found. Further, association of CHW contacts and specific messaging with health outcomes were significantly affected by socio-economic determinants.2 or more contacts along with specific messaging increased the odds of 4+ ANC to a higher degree among illiterate women compared to literate women(AOR:3.39, 95% CI:2.28-5.04 vs AOR:1.44, 95% CI:1.09-1.92). Similarly, the odds of facility delivery increased to a higher degree among lower wealth women compared to higher wealth women (AOR:3.41, 95% CI:2.47-4.71 vs. AOR:1.53, 95% CI: 1.09-2.15).
Specific messaging, along with CHW contacts, have a higher magnitude of effects on the marginalized population. This study provides evidence for adjusting implementation strategies based on socio-economic determinants to achieve equitable health service utilization. However, further research on training of CHW on heterogeneous interaction is recommended
Key messages
There exists differential effects of quantity and quality of contact by community health workers on health service utilization across the different socio-economic strata. Implementation agencies in the LMIC can reduce health inequity by shifting from coverage-oriented target approach towards more prioritized and focused interaction across socio-economic groups.

Abstract
Central nervous system tuberculosis may present as meningitis, tuberculoma, abscesses, cerebritis or miliary
tuberculosis. The most common site of tuberculoma has been reported to be at the grey-white matter junction
and the periventricular region. They may even be found in the epidural, subdural and subarachnoid spaces,
and the brain stem. Although tuberculosis is very common in developing countries, with the increasing
prevalence of immunosuppression owing to human immunodeficiency virus and patients surviving
chemotherapy or organ transplantation, the incidence of tubercular infections has been rising in developed
countries. The authors report a 15-year-old boy of intracranial tuberculoma at the basal, suprasellar and
perimesencephalic cisterns in a patient. Tuberculous involvement was noted in a racemose pattern in the
subarachnoid space. The patient’s clinical symptoms resolved with no recurrence of symptoms but only
persistence of the radiological abnormality after antitubercular chemotherapy.

Abstract
Abstract
Introduction
Sleep is a critical behavior predicting mental health and depressive symptomatology in young adults.The extant scientific literature generally focuses on self-reported sleep measures over relatively short time frames. Here, we examine whether actigraphy-measured sleep variables early in the academic semester predict depressive symptomatology at the end of the semester among first and second year college students. There is currently debate in the sleep literature about which sleep variables are the most robust predictors of depression among young adults. In this study, we evaluate total sleep time, midpoint sleep time, and sleep variability where variability is defined by the mean-squared successive difference (MSSD) of midpoint sleep as predictors of depression.
Methods
The sample consisted of 160 first and second year college students at a private American university. The students completed a beginning and end of semester assessment of depressive symptomatology using the Center for Epidemiologic Studies Depression Scale (CES-D), and wore a Fitbit throughout the semester to capture sleep features of interest: total sleep time (TST), midpoint sleep, and midpoint MSSD.
Results
When controlling for beginning of semester CES-D, early semester (weeks 3–6) midpoint sleep MSSD significantly (p < 0.05) predicted increased end of semester CES-D. These effects were specific to the sleep variability measure (MSSD). Total sleep time and sleep chronotype (i.e. midpoint sleep) were not significant predictors of end of semester depressive symptomatology.
Conclusion
Early semester sleep window variability among college freshmen, particularly during stressful midterm exams, is a robust risk factor for depression among college students. This work contributes to initial actigraphy studies suggesting that MSSD measures of sleep window variability foster increased mental health risks among young people. This work calls for further investigation to understand possible causal relationships between sleep variability and mental health.

Abstract
BACKGROUND AND AIM The quality of day-old chicks is a cornerstone to successful poultry production. Chicks with a poor quality start slowly in the field and may have high feed intake, poor growth rate, and poor feed conversion ratio. The current study aimed to assess chick quality challenges encountered from day-old chicks hatched in most commercial hatcheries in Ghana. MATERIALS AND METHODS A total of 300 day-old chicks each were obtained from commercial hatcheries in Ghana and Europe. The chicks were labeled as locally hatched broiler day-old chicks (LBDOC) and foreign hatched broiler day-old chicks (FBDOC), respectively. Chicks were reared and monitored from day old to 21 days post-hatch. Sample of chicks (n=25) from each hatchery was euthanized weekly at 1, 7, 14, and 21 days and blood samples collected for analysis. The parameters measured included physical, hematological, immunological, histological, and bacteriological characteristics. All data were analyzed by SAS Proc GLM at p<0.05. RESULTS The live weight of chicks was higher in FBDOC compared to LBDOC on the 1st day. The chick length and shank length of FBDOC were longer than the LBDOC. The 7-day chick mortality was 6% in LBDOC as compared to 1.5% in FBDOC. The LBDOC also had a higher wet and dry residual yolk sac percentages as well as higher residual yolk sac fluid volume than the FBDOC. The rate of yolk sac disappearance of the FBDOC was higher than the LBDOC. More than half of the LBDOC had developed navel strings and leaky navel compared to FBDOC. The LBDOC recorded Escherichia coli, Proteus, Streptococcus spp., and Gram-negative bacteria in the residual yolk sac isolated through the 21 days while FBDOC recorded E. coli, Proteus, and Gram-negative bacteria. The intestinal villi count, lengths, width, and surface area were all not significantly different. The blood monocyte levels appeared higher in FBDOC than LBDOC, which give evidence of higher immunity in FBDOC than LBDOC. CONCLUSION The results indicate a challenging situation in maintaining the quality of locally hatched broiler day-old-chicks compared to foreign hatched broiler-day-old-chicks. The study demonstrates that chick quality impact goes beyond the physical characteristics of chick weight and chick length, and the higher performance of FBDOC may be influenced by compliance with international hatchery standards and vaccination protocols.

Abstract
Abstract
Importance
Severe mitral valve insufficiency (MR) is managed using mitral valve replacement or repair. Transcatheter mitral valve repair (TMVR) is an emerging non-invasive treatment option for MR. Cancer patients stand to benefit from non-invasive treatment of MR given the nature of this intervention. Objective:We sought to assess the relative utilization, outcomes, and dispositions associated with TMVR vs. surgical mitral valve procedures (SMVP) in cancer patients.
Methods
The 2012–2015 National Inpatient Sample, a retrospective observational study was queried using ICD-9 codes for adults >18 years with comorbid MR (ICD-9 – 424.0) and cancer without metastatic disease. To maintain a homogenous study population and to limit confounding, those with mitral stenosis, rheumatic disease, infective endocarditis, aortic valve disease, or those undergoing any other vascular or cardiac surgery in the same admission were excluded from the analysis. Multiple in-hospital and disposition outcomes were evaluated. Since the baseline population undergoing SMVP (ICD-9: 35.23, 35.24, 35.12) is quite different from TMVR (ICD-9: 35.97), parallel analyses for outcomes and dispositions were presented but no direct statistical comparisons.
Results
A total of 410,175 out of 2,449,010 patients with mitral insufficiency were found to have non-metastatic cancer (16.7%). A total of 3,600 TMVR procedures were performed during the study period. Over the study period, there has been an increase in the proportion of patients undergoing TMVR among all patients undergoing mitral valve procedures (figure). The increase is higher in cancer patients in the most recent year (14.2% vs. 8.2%, p<0.0001). The four major cancers comprise of 50% of these TMVR patients. TMVR was associated with 1.4% vs. 2.2% in-hospital mortality (p=0.55), 0.7% vs. 0.8% stroke (p=0.87), 9.2% vs. 11.8% major bleeding (p=0.31), 14.1% vs. 16.5% acute kidney injury (p=0.52), 62.0% vs. 64.6% home discharge (p=0.58), and 13.3% vs. 12.0% discharge to nursing home (p=0.58) among cancer vs. non-cancer patients, respectively. On the other hand, SMVP was associated with 3.1% vs. 3.5% in-hospital mortality (p=0.35), 2.6% vs. 3.1% stroke (p=0.16), 35.0% vs. 30.5% major bleeding (p<0.0001), 19.5% vs. 19.6% acute kidney injury (p=0.88), 32.8% vs. 38.6% home discharge (p<0.0001), 37.2% vs. 35.0% home health care use (p<0.0001), and 26.8 vs. 22.8% discharge to nursing home (p=0.05), among cancer vs. non-cancer patients respectively.
TMVR percent in mitral valve procedures
Conclusion
TMVR utilization for MR in cancer has steadily increased in both cancer and non-cancer patients, although it is proportionately higher among cancer patients in recent years. Overall, TMVR was associated with low in-hospital mortality and a similar safety profile in cancer and non-cancer patients, while SMVP appears to have a slightly worse safety profile in cancer patients. Our findings, suggest that TMVR is a reasonable strategy in selective cancer patients with MR.

Abstract
Abstract
Importance
Cancer patients with severe AS are often ineligible for surgical aortic valve replacement (SAVR). Transcatheter aortic valve replacement (TAVR) is an emerging non-invasive treatment option for severe AS. Cancer patients likely stand to benefit from TAVR given its non-invasive nature; however, there is a paucity of data regarding the comparative effectiveness of TAVR vs. SAVR in cancer. We sought to assess the relative utilization, outcomes, and dispositions associated with TAVR vs. SAVR in cancer and non-cancer patients.
Methods
The US-based National Inpatient Sample was queried between 2012 and 2015 using ICD-9 codes for adults>18 years with comorbid AS and cancer without metastatic disease. Multiple in-hospital and disposition outcomes were evaluated. Comparison of TAVR vs SAVR required propensity score estimation using demographic, socio-economic, comorbidity, and hospital specific variables. A standardized morbidity ratio (SMR) weight was calculated by assigning TAVR a weight of 1, and those undergoing SAVR weight of PS/(1-PS). SMR-weighted generalized logistic regression was conducted to estimate the average effect of TAVR compared with SAVR. Finally, the Cochran–Mantel–Haenszel (CMH) test for propensity-matched data was utilized to compare the effect modification of cancer on these outcomes.
Results
A total of 979,912 out of 5,611,173 patients with AS were found to have non-metastatic cancer (17.5%). Average Elixhauser's mortality score of patients undergoing TAVR and SAVR was 8.9 vs. 8.1 and 8.5 vs. 7.1 for cancer vs. non-cancer respectively (p<0.0001). Over time, patients undergoing AVR increased in both groups, primarily driven by significantly increased rates of TAVR utilization in the cancer group. Over the study time period, an increase in the proportion of patients undergoing TAVR among all patients undergoing AVR was noted (figure) with 21.8% and 19.6% patient with prostate and breast cancer in 2015. TAVR in cancer patients was associated with lower odds of acute kidney injury [AKI; odds ratio (OR): 0.6, 95% confidence interval (CI): 0.5- 0.8], cardiogenic shock [OR: 0.6 (0.4–0.8)] and major bleeding [OR: 0.4 (0.3–0.5)] with no difference in in-hospital mortality and stroke compared to SAVR. Additionally, TAVR was associated with higher odds of home-discharge [OR: 1.9 (1.7–2.2)], and lower need for nursing facility transfer [OR: 0.7 (0.6–0.8) compared to SAVR among cancer patients. Similar outcomes are noted in the non-cancer cohort upon comparing TAVR to SAVR. However, favorable effect-modification of cancer was noted in regard to AKI (p=0.003), home discharge (p<0.0001), and less nursing facility transfer (p=0.0003), suggesting safety.
Conclusions
Compared to patients without cancer, the utilization of AVR in cancer patients has steadily increased. The benefits of TAVR over SAVR appear to extend to patients, regardless of cancer status. TAVR might be a more suitable procedure for cancer patients with AS.

Abstract
The present study evaluates the seasonal variation of estimated error in downscaled land surface temperatures (LST) over a heterogeneous urban land. Thermal sharpening (TsHARP) downscaling algorithm has been used with a separate combination of four selected remote sensing indices. This study assesses the capability of TsHARP technique over mixed land use/land covers (LULC) by analyzing the correlation between LST and remote sensing indices, namely, normalized difference built-up index (NDBI), normalized difference vegetation index (NDVI), normalized difference water index (NDWI), and normalized multi-band drought index (NMDI) and by determining the root mean square error (RMSE) and mean error (ME) produced by downscaled LST. Landsat 8 OLI (Operational Land Imager) and TIRS (Thermal Infrared Sensor) images have been used for pre-monsoon, monsoon, post-monsoon, and winter seasons in 2014 covering the whole Raipur City, India. The RMSE of the downscaled LST decreases from 120 to 480 m spatial resolution in all the four seasons. It is concluded that NDBI is the most effective LULC index having the least error produced in TsHARP downscaling technique, irrespective of any season. Post-monsoon season reflects the most successful result followed by monsoon season. Even in the monsoon season of high vegetation coverage, NDBI presents a lower range of downscaled error compared to NDVI. This indicates better performance of NDBI in detecting the spatial and temporal distribution of mixed urban land.

For this, a criterion has been proposed based on the observed daily gridded maximum temperature (Tmax) datasets, which can be used for real-time prediction as well. A heat wave day is identified when either (1) Tmax (a)≥ its climatological 95th percentile (calculated from daily values during March-June and for 1981-2010), (b) >36 °C, and (c) its departure from normal is >3.5 °C, Or, (2) when the Tmax >44 °C. Three heat wave prone regions, namely, northwest, southeast and northwest-southeast regions are recognized and heat wave spells of minimum consecutive six days are identified objectively for each region during 1981-2018. It is noticed that the prediction system has reasonable skill in predicting the heat waves over heat wave prone regions of India. Forecast verification of heat wave spells during 2003-2018 reveals that the prediction system has great potential in providing overall indication about the onset, duration and demise of the forthcoming heat wave spell with sufficient lead time albeit with some spatio-temporal error.

Abstract
Hepatocellular carcinoma (HCC) develops in the context of chronic inflammatory liver disease and has an extremely poor prognosis. An immunosuppressive tumor microenvironment may contribute to therapeutic failure in metastatic HCC. Here, we identified unique molecular signatures pertaining to HCC disease progression and tumor immunity by analyzing genome-wide RNA-Seq data derived from HCC patient tumors and non-tumor cirrhotic tissues. Unsupervised clustering of gene expression data revealed a gradual suppression of local tumor immunity that coincided with disease progression, indicating an increasingly immunosuppressive tumor environment during HCC disease advancement. IHC examination of the spatial distribution of CD8+ T cells in tumors revealed distinct intra- and peri-tumoral subsets. Differential gene expression analysis revealed an 85-gene signature that was significantly upregulated in the peri-tumoral CD8+ T cell-excluded tumors. Notably, this signature was highly enriched with components of underlying extracellular matrix, fibrosis, and epithelial-mesenchymal transition (EMT). Further analysis condensed this signature to a core set of 23 genes that are associated with CD8+ T cell localization, and were prospectively validated in an independent cohort of HCC specimens. These findings suggest a potential association between elevated fibrosis, possibly modulated by TGF-β, PDGFR, SHH or Notch pathway, and the T cell-excluded immune phenotype. Indeed, targeting fibrosis using a TGF-β neutralizing antibody in the STAM™ model of murine HCC, we found that ameliorating the fibrotic environment could facilitate redistribution of CD8+ lymphocytes into tumors. Our results provide a strong rationale for utilizing immunotherapies in HCC earlier during treatment, potentially in combination with anti-fibrotic therapies.

Abstract
A research project on comparative international studies of osteoporosis using isotope techniques was organized by the International Atomic Energy Agency (IAEA) with the participation of 12 countries (Brazil, Canada, Chile, China, Croatia, Hungary, Philippines, Russia, Singapore, South Africa, Turkey, and the United Kingdom). Participating centers in 11 countries (all but the UK) made measurements and collected data on men and women aged 15 to 49 years. In addition to studies of bone mineral density (BMD) at the femoral neck and lumbar spine using DEXA, anthropometric, lifestyle, and nutritional data were also collected. The results of the nutritional studies are reviewed in this paper. Overall, about 8% of the observed variability in spine BMD could be attributed to nutritional factors in men and women; in men, no such relationship could be determined. No single nutritional component (not even calcium) stood out as being of particular importance across all participating centers.

Abstract
Growth and survival of Clarias batrachus juveniles (10-day old) fed probiotic Bacillus cereus (KR809412) encapsulated live feed (chironomid larvae) have been evaluated after differential exposure to the pathogenic Aeromonas hydrophila (MTCC 1739). Catfish juveniles were stocked at a density of 30 fish per tank in five experimental groups (T1-T5) along with a control group in triplicate and fed twice @ 5% of body weight day-1 for four weeks. Groups T1 and T2 were fed probiotic-encapsulated (PR) or pathogen-inoculated (PGN) live feed respectively, for initial three weeks. During this period groups T3 (PGN-PR-PR), T4 (PR-PGN-PR), and T5 (PR-PR-PGN) were differentially exposed to the pathogen. Live feed without probiotic and pathogen was offered to the control group throughout the experimental period and all other treatment groups (T1-T5) during the 4th week. Continuous exposure to probiotics in group T1 resulted in significantly higher (P<0.05) specific growth rate (SGR, % d-1) and survivability than other groups, whereas, pathogen exposed and probiotic deprived group (T2) noticed with the lowest SGR and the highest mortality. Among other treatment groups (T3, T4 and T5), group T4 resulted in improved SGR and survivability. The coefficient (r value) of 0.867 along with regression slope suggested a positive correlation (0.01 levels) between RNA: DNA and SGR. The study might suggest protective effects of probiotic B. cereus in pathogen exposed C. batrachus juveniles.SAARC J. Agri., 16(1): 105-113 (2018)

Abstract
The development of drug delivery systems with microencapsulated therapeutic agents is a promising approach to the sustained and controlled delivery of various drug molecules. The incorporation of dual release kinetics to such delivery devices further adds to their applicability. Herein, novel core–shell scaffolds composed of sodium deoxycholate and trishydroxymethylaminomethane (NaDC–Tris) have been developed with the aim of delivering two different drugs with variable release rates using the same delivery vehicle. Data obtained from XRD studies, sol–gel transition temperature measurement, rheology and fluorescence studies of the core–shell systems indicate a significant alteration in the core and the shell microstructural properties in a given system as compared to the pure hydrogels of identical compositions. The release of the model drugs Fluorescein (FL) and Rhodamine B (RhB) from the shell and the core, respectively, of the two core–shell designs studied exhibited distinctly different release kinetics. In the 25@250 core–shell system, 100% release of FL from the shell and 19% release of RhB from the core was observed within the first 5 hours, while 24.5 hours was required for the complete release of RhB from the core. For the 100@250 system, similar behaviour was observed with varied release rates and a sigmoidal increase in the core release rate upon disappearance from the shell. Cell viability studies suggested the minimal toxicity of the developed delivery vehicles towards NMuMG and WI-38 cells in the concentration range investigated. The reported core–shell systems composed of a single low molecular weight gelator with dual release kinetics may be designed as per the desired application for the consecutive release of therapeutic agents as required, as well as combination therapy commonly used to treat diseases such as diabetes and cancer.

Abstract
Safety and efficacy data on pegylated asparaginase (PEG-ASP) in adult acute lymphoblastic leukaemia (ALL) induction regimens are limited. The UK National Cancer Research Institute UKALL14 trial NCT01085617 prospectively evaluated the tolerability of 1000 IU/m2 PEG-ASP administered on days 4 and 18 as part of a five-drug induction regimen in adults aged 25-65 years with de novo ALL. Median age was 46.5 years. Sixteen of the 90 patients (median age 56 years) suffered treatment-related mortality during initial induction therapy. Eight of the 16 died of sepsis in combination with hepatotoxicity. Age and Philadelphia (Ph) status were independent variables predicting induction death >40 versus ⩽40 years, odds ratio (OR) 18.5 (2.02-169.0), P=0.01; Ph- versus Ph+ disease, OR 13.60 (3.52-52.36), P<0.001. Of the 74 patients who did not die, 37 (50.0%) experienced at least one grade 3/4 PEG-ASP-related adverse event, most commonly hepatotoxicity (36.5%, n=27). A single dose of PEG-ASP achieved trough therapeutic enzyme levels in 42/49 (86%) of the patients tested. Although PEG-ASP delivered prolonged asparaginase activity in adults, it was difficult to administer safely as part of the UKALL14 intensive multiagent regimen to those aged >40 years. It proved extremely toxic in patients with Ph+ ALL, possibly owing to interaction with imatinib.

Abstract
This study was designed to explore the cyproterone acetate (CPA)-induced andrological hypofunction and its correction by oral administration of lycopene. In this concern, spermatogenic, biochemical, histological and genomic profiles were studied. Cyproterone acetate administration for 1 month helped to develop infertile model rats. A significant recovery was noted in sperm motility, sperm count, sperm viability, hypo-osmotic swelling tail-coiled spermatozoa; activities of testicular ∆5 , 3β-hydroxysteroid dehydrogenase (HSD), 17β-HSD, catalase (CAT) and superoxide dismutase (SOD); and levels of conjugated diene (CD), malondialdehyde (MDA), testicular cholesterol and serum testosterone after the administration of lycopene at 1.5 mg/0.5 ml Tween-80/100 g body weight/day for last 1 month to infertile model rats. Simultaneously, qRT-PCR study of Bax, Bcl-2, caspase-3, ∆5 , 3β-HSD and 17β-HSD genes in testicular tissue showed a significant rectification towards the control in CPA-pre-treated cum CPA-lycopene-cotreated rats. Side-by-side histological and histometric studies showed a significant correction in qualitative analysis of spermatogenesis and seminiferous tubular diameter (STD) in CPA-pre-treated cum CPA-lycopene-cotreated rats. Lycopene showed outstanding efficacy in the management of CPA-induced testicular hypofunction with special reference to correction in oxidative stress-induced testicular apoptosis at genomic level.

Abstract
PURPOSE Enteric parasitic infestation is a major public health problem in developing countries. Parasites such as Cryptosporidium spp., Cyclospora spp., Cystoisospora spp. and Microsporidia may cause severe diarrhoea among immunocompromised patients. There is scanty data on their frequency among immunocompetent patients. Accordingly, we studied the frequency of enteric opportunistic parasites among immunocompetent patients with diarrhoea from northern India; we also performed genetic characterisation of Cryptosporidia and Microsporidia among them. PATIENTS AND METHODS Stool samples from 80 immunocompetent patients with diarrhoea, and 110 healthy controls were examined. Parasites were detected by direct microscopy, modified acid-fast (Kinyoun's) and modified trichrome stain. Polymerase chain reaction--restriction fragment length polymorphism was used for genetic characterisation of selected species such as Cryptosporidia and Microsporidia. RESULTS Enteric parasites were detected in 16/80 (20%) patients (mean age 28.8±20 years, 45, 56% males) and in 2/110 (1.8%) healthy controls (P=0.00007). Parasites detected were Cryptosporidium spp. (8/16, 50.0%), Cystoisospora spp. (4/16, 25%), Microsporidia (1/16, 6.25%), Cyclospora spp. (1/16, 6.25%) and Giardia spp. (1/16, 6.25%). One patient had mixed infection with Cystoisospora spp. and Giardia spp. The species of Cryptosporidia and Microsporidia detected were Cryptosporidium hominis and Enterocytozoon bieneusi, respectively. Parasites were more often detected in younger patients (≤20 years of age) than in older. Most of the parasite infected patients presented with chronic diarrhoea. CONCLUSION Opportunistic enteric parasitic infestation was more common among immunocompetent patients with diarrhoea than healthy subjects. Special staining as well as molecular methods are essential for appropriate diagnosis of these parasites.

Abstract
Background: The World Health Organization (WHO) Western Pacific Region (WPR) Guidelines on verification of measles elimination were established in 2012. This article outlines Australia’s approach to addressing the guideline’s five lines of evidence, which led to formal verification of elimination by the WHO Regional Verification Commission (RVC) in March 2014. Methods: The criteria were addressed using national measles notifications, data from selected laboratories, the national childhood immunization register, and three national serosurveys (1998/1999, 2002, 2007). Results: Australia met or exceeded all indicator targets with either national or sentinel data. Laboratory and epidemiological surveillance were of high quality, with 85% of cases documented as imported/import-related (target 80%); coverage with the first dose of measles vaccine was close to 94% in 2008–2012 and second dose coverage increased to 91% in 2012 (target >95%). There is ongoing commitment by the Australian Government to increase immunization coverage, and the absence of sustained transmission of any single measles genotype was demonstrated. Conclusions: This is the first documentation of the successful application of the WPR RVC guidelines. The indicators afford some flexibility but appear to provide appropriate rigor to judge achievement of measles elimination. Our experience could assist other countries seeking to verify their elimination status.
