Abstract
The Mars 2020 Perseverance rover is equipped with a next-generation engineering camera imaging system that represents an upgrade over previous Mars rover missions. These upgrades will improve the operational capabilities of the rover with an emphasis on drive planning, robotic arm operation, instrument operations, sample caching activities, and documentation of key events during entry, descent, and landing (EDL). There are a total of 16 cameras in the Perseverance engineering imaging system, including 9 cameras for surface operations and 7 cameras for EDL documentation. There are 3 types of cameras designed for surface operations: Navigation cameras (Navcams, quantity 2), Hazard Avoidance Cameras (Hazcams, quantity 6), and Cachecam (quantity 1). The Navcams will acquire color stereo images of the surface with a 96 ∘ × 73 ∘ field of view at 0.33 mrad/pixel. The Hazcams will acquire color stereo images of the surface with a 136 ∘ × 102 ∘ at 0.46 mrad/pixel. The Cachecam, a new camera type, will acquire images of Martian material inside the sample tubes during caching operations at a spatial scale of 12.5 microns/pixel. There are 5 types of EDL documentation cameras: The Parachute Uplook Cameras (PUCs, quantity 3), the Descent stage Downlook Camera (DDC, quantity 1), the Rover Uplook Camera (RUC, quantity 1), the Rover Descent Camera (RDC, quantity 1), and the Lander Vision System (LVS) Camera (LCAM, quantity 1). The PUCs are mounted on the parachute support structure and will acquire video of the parachute deployment event as part of a system to characterize parachute performance. The DDC is attached to the descent stage and pointed downward, it will characterize vehicle dynamics by capturing video of the rover as it descends from the skycrane. The rover-mounted RUC, attached to the rover and looking upward, will capture similar video of the skycrane from the vantage point of the rover and will also acquire video of the descent stage flyaway event. The RDC, attached to the rover and looking downward, will document plume dynamics by imaging the Martian surface before, during, and after rover touchdown. The LCAM, mounted to the bottom of the rover chassis and pointed downward, will acquire 90 ∘ × 90 ∘ FOV images during the parachute descent phase of EDL as input to an onboard map localization by the Lander Vision System (LVS). The rover also carries a microphone, mounted externally on the rover chassis, to capture acoustic signatures during and after EDL. The Perseverance rover launched from Earth on July 30th, 2020, and touchdown on Mars is scheduled for February 18th, 2021.

Abstract
Embryonal rhabdomyosarcoma (RMS) of the cervix. Subtypes of embryonal RMS. Disease of adolescence. Fertility preservation. Lack of standard treatment.
Embryonal rhabdomyosarcoma (RMS) of the cervix is a rare entity, encountered mainly in the first two decades of life. The literature consists mainly of case reports and few small case series, and no standard treatment guidelines are available. As this is a disease of adolescence, fertility preservation in well selected cases is of paramount importance. We report 3 cases of cervical RMS, in adolescents highlighting the clinical presentation, diagnosis and management.

Abstract
AIMS To evaluate whether and what combinations of diabetes quality metrics were achieved in a multicentre trial in South Asia evaluating a multicomponent quality improvement intervention that included non-physician care coordinators to promote adherence and clinical decision-support software to enhance physician practices, in comparision with usual care. METHODS Using data from the Centre for Cardiometabolic Risk Reduction in South Asia (CARRS) trial, we evaluated the proportions of trial participants achieving specific and combinations of five diabetes care targets (HbA1c <53 mmol/mol [7%], blood pressure <130/80 mmHg, LDL cholesterol <2.6 mmol/L, non-smoking status, and aspirin use). Additionally, we examined the proportions of participants achieving the following risk factor improvements from baseline: ≥11-mmol/mol (1%) reduction in HbA1c , ≥10-mmHg reduction in systolic blood pressure, and/or ≥0.26-mmol/l reduction in LDL cholesterol. RESULTS Baseline characteristics were similar in the intervention and usual care arms. Overall, 12.3%, 29.4%, 36.5%, 19.5% and 2.2% of participants in the intervention group and 16.2%, 38.3%, 31.6%, 11.3% and 0.8% of participants in the usual care group achieved any one, two, three, four or five targets, respectively. We noted sizeable improvements in HbA1c , blood pressure and cholesterol, and found that participants in the intervention group were twice as likely to achieve improvements in all three indices at 12 months that were sustained over 28 months of the study [relative risk 2.1 (95% CI 1.5,2.8) and 1.8 (95% CI 1.5,2.3), respectively]. CONCLUSIONS The intervention was associated with significantly higher achievement of and greater improvements in composite diabetes quality care goals. However, among these higher-risk participants, very small proportions achieved the complete group of targets, which suggests that achievement of multiple quality-of-care goals is challenging and that other methods may be needed in closing care gaps.

Abstract
BACKGROUND Spina bifida is the most common fetal anomaly of the central nervous system, which affects approximately 1:1000 live births in the United States. Myelomeningocele (MMC) is the most common presentation of spina bifida, representing half of these cases. Given the deformation to the spinal cord and the nerve roots, this defect may result in significant morbidity to infants and major life-long disabilities. In this study we aimed to identify maternal and fetal characteristics associated with expectant management or termination of pregnancy in the setting of antenatally diagnosed MMC. We hypothesized that the level of the defect would correlate with patient's decision to continue the pregnancy. METHODS A retrospective cohort analysis was performed with patients who had presented to the Cleveland Clinic Fetal Care Center between 2005-2017. RESULTS Our data showed 36% of patients with antenatal diagnosis of MMC elected for second trimester terminations versus 64% who chose to continue their pregnancy and deliver either by cesarean section or vaginal delivery. Based on ultrasound findings, there were no significant differences between these two groups. Maternal body mass index was significantly higher in those who continued pregnancies (p = 0.036). In addition, the fetal diagnostic methods chosen by patients were significantly different. Those who elected to terminate were more likely to pursue amniocentesis (p = 0.03) and less likely to opt for MRI characterization of the fetus (p = 0.007). CONCLUSION We conclude, in the setting of fetal MMC diagnosed during pregnancy, patients often rely less on the associated ultrasonographic findings. Personal decisions likely influence the choice of other fetal diagnostic modalities. Other than BMI, we did not see an association between maternal factors and decisions regarding second trimester pregnancy termination.

Abstract
BACKGROUND This study aimed to determine the impact of preoperative exposure to intravenous contrast for CT and the risk of developing postoperative acute kidney injury (AKI) in patients undergoing major gastrointestinal surgery. METHODS This prospective, multicentre cohort study included adults undergoing gastrointestinal resection, stoma reversal or liver resection. Both elective and emergency procedures were included. Preoperative exposure to intravenous contrast was defined as exposure to contrast administered for the purposes of CT up to 7 days before surgery. The primary endpoint was the rate of AKI within 7 days. Propensity score-matched models were adjusted for patient, disease and operative variables. In a sensitivity analysis, a propensity score-matched model explored the association between preoperative exposure to contrast and AKI in the first 48 h after surgery. RESULTS A total of 5378 patients were included across 173 centres. Overall, 1249 patients (23·2 per cent) received intravenous contrast. The overall rate of AKI within 7 days of surgery was 13·4 per cent (718 of 5378). In the propensity score-matched model, preoperative exposure to contrast was not associated with AKI within 7 days (odds ratio (OR) 0·95, 95 per cent c.i. 0·73 to 1·21; P = 0·669). The sensitivity analysis showed no association between preoperative contrast administration and AKI within 48 h after operation (OR 1·09, 0·84 to 1·41; P = 0·498). CONCLUSION There was no association between preoperative intravenous contrast administered for CT up to 7 days before surgery and postoperative AKI. Risk of contrast-induced nephropathy should not be used as a reason to avoid contrast-enhanced CT.

Abstract
Background:Scleroderma has been associated with increased risk of cardiovascular events, however,studies on this from India are sparse.We evaluated clinical and serological factors associated with subclinical atherosclerosis in Indian patients with scleroderma, in a cross-sectional design.Objectives:To compare carotid intima-medial thickness (CIMT, mean value of both carotids) as a measure of subclinical atherosclerosis (SCA) between patients with scleroderma (n=61) fulfilling 2013 ACR/EULAR criteria, and healthy controls (n=41).- To compare clinical (body mass index – BMI, waist-hip ratio – WHR, fasting lipid profile) and serological factors (microparticles, endothelial microparticles, inflammatory cytokines associated with increased cardiovascular risk) between patients with scleroderma and healthy controls.- To identify factors associated with SCA in scleroderma patients.Methods:Subclinical atherosclerosis(SCA) was defined by presence of carotid plaques, or increased CIMT >2 standard deviations compared with Indian reference standards for age and sex. Total microparticles (TMP) were measured of plasma after ultracentrifugation as per previously described protocol using microbeads of 3 μm size (TMP were of size 0.1-1 μm); of these, microparticles positive for CD31 and CD142 were endothelial microparticles (EMP). Serum cytokines (IL-1, IL-6, TNF-α, IL-17) were measured by ELISA using manufacturer instructions. Linear regression was used to identify the determinants of CIMT in scleroderma. Binomial logistic regression was used to identify factors associated with subclinical athersclerosis in scleroderma.VariablePatients with scleroderma (n=61)Healthy controls (n=41)p valueAge37.8 ± 11.9235.37 ± 6.690.2375Gender (M:F)11:506:350.6516Diabetes/Hypertension/Tobacco use1/2/00/0/0NSBody mass index (kg/m2)20.11 ± 3.8224.38 ± 4.45<0.0001Waist-hip ratio0.86 ± 0.110.89 ± 0.070.1251Total cholesterol (mg/dL)142.5 ± 30.7147.3 ± 39.50.4948Triglycerides (mg/dL)99.4 ± 37121.4 ± 460.0087HDL cholesterol (mg/dL)46.9 ± 4.946.1 ± 4.20.4029LDL cholesterol (mg/dL)93.6 ± 10.593.3 ± 7.50.8520VLDL cholesterol (mg/dL)19.9 ± 7.424.7 ± 9.70.0057Carotid intima-medial thickness (mm)0.68 ± 0.100.53 ± 0.03<0.0001Total microparticles (per±L)12913 ± 24936272 ± 1533<0.0001Endothelial microparticles (per±L)2623 ± 1032829 ± 439.5<0.0001Serum IL-1±(pg/mL)38.19 ± 13.4631.38 ± 18.290.0326IL-6 (pg/mL)176.6 ± 85.74128.9 ± 53.610.0020IL-17 (pg/mL)56.3 ± 20.4553.89 ± 20.510.5611TNF±(pg/mL)49.65 ± 26.7142.09 ± 30.410.1879Results:Despite lower BMI, triglycerides and VLDL cholesterol, CIMT was significantly higher in patients with scleroderma.

Abstract
Plant genetic resources (PGR) are the foundation of agriculture as well as food and nutritional security.
The ICAR-NBPGR is the nodal institution at national level for management of PGR in India under the umbrella
of Indian Council of Agricultural Research (ICAR), New Delhi. India being one of the gene-rich countries faces a
unique challenge of protecting its natural heritage while evolving mutually beneficial strategies for germplasm
exchange with other countries. The Bureaus activities include PGR exploration, collection, exchange, characterization,
evaluation, conservation and documentation. It also has the responsibility to carry out quarantine of
all imported PGR including transgenics meant for research purposes. The multifarious activities are carried out
from ICAR-NBPGR headquarters and its 10 regional stations located in different agro-climatic zones of India. It
has linkages with international organizations of the Consultative Group on International Agricultural Research
(CGIAR) and national crop-based institutes to accomplish its mandated activities. NBPGR collects and acquires
germplasm from various sources, conserves it in the Genebank, characterizes and evaluates it for different traits
and provides ready material for breeders to develop varieties for farmers. ICAR-NBPGR encompasses the National
Genebank Network and at present, the National Genebank conserves more than 0.40 million accessions. NBPGR
works in service-mode for effective utilization of PGR in crop improvement programmes which depends mainly
on its systematic characterization and evaluation, and identification of potentially useful germplasm. NBPGR is
responsible for identifying trait-specific pre-adapted climate resilient genotypes, promising material with disease
resistance and quality traits which the breeders use for various crop improvement programmes. The system has
contributed immensely towards safeguarding the indigenous and introducing useful exotic PGR for enhancing
the agricultural production. Presently, our focus is on characterization of ex situ conserved germplasm and
detailed evaluation of prioritized crops for enhanced utilization; assessment of impact of on-farm conservation
practices on genetic diversity; genome-wide association mapping for identification of novel genes and alleles for
enhanced utilization of PGR; identification and deployment of germplasm/landraces using climate analog data;
validation of trait-specific introduced germplasm for enhanced utilization.
Key words: plant genetic resources; gene banks; wild relatives; biotic and abiotic stresses; marker-assisted
selection.

Abstract
AIM To characterize a lipopolysaccharide (LPS)-treated dentine tissue model (LPS dentine) to analyse the efficacy of polycationic chitosan nanoparticles (CSnp) and/or dexamethasone conjugate chitosan nanoparticles (Dex-CSnp) on the viability/differentiation potential of stem cells from apical papilla (SCAP) when exposed to LPS dentine. A further aim was to understand the effect of macrophage-dependent inflammation on SCAP migration in the presence of LPS dentine. METHODOLOGY A total of 88 dentine slabs were used. TOF-SIMS analysis was performed amongst the LPS-treated and untreated dentine groups (n = 2/group). The study was conducted using four dentine groups: no treatment (control); LPS treatment only; LPS treatment followed by CSnp conditioning; and LPS treatment followed by Dex-CSnp conditioning groups. SCAP adherence, viability, differentiation and biomineralization potential on dentine from different groups were studied using fluorescent and scanning electron microscopy. Inflammation by macrophages in response to LPS dentine was quantified, and effect on SCAP migration was analysed. Statistical analysis was performed using Student's t-test with a significance level of P < 0.05. RESULT TOF-SIMS analysis confirmed LPS contamination. LPS dentine affected SCAP viability but not adherence to dentine (P < 0.001). Conditioning of LPS dentine with either nanoparticles improved SCAP viability (P < 0.01) and rescued other LPS related adverse effects on SCAPs, such as F-actin disruption, decrease in differentiation/biomineralization potential. IL-6 produced by macrophages in response to LPS-treated dentine impeded SCAP migration (P < 0.001), diminished on CSnp and Dex-CSnp conditioning groups (P < 0.01). CONCLUSION This study developed an LPS-dentine model and highlighted the ability of CSnp and Dex-CSnp to promote stem cell viability, migration, differentiation potential and reduce inflammation, providing an environment conducive for tissue regeneration/repair.

Abstract
Lithium-doped vanadates (V2−xLixO5−δ (0.15 ≤ x ≤ 0.30)) are synthesized by melt-quench method. The physical, structural, optical, thermal and conducting properties of as-quenched samples are investigated using various experimental techniques to study their suitability for electrolyte in battery/solid oxide fuel cell application. X-ray diffraction (XRD) patterns confirm the formation of three different crystalline phases. FTIR and Raman spectra indicate that the doping of Li2O into V2O5 leads to a transition from VO5 into VO4 structural unit. The optical diffused reflectance spectra revealed that the optical band gap (Eg) decreases from 2.2 to 2.08 eV while Urbach energy (EU) increases (0.31–0.41 eV) with the addition of Li2O content in place of vanadium. The thermal stability is studied by thermogravimetric analyser (TGA). The DC conductivity of the present samples is increased from 0.08 to 0.12 Scm−1 at 450 °C with Li2O doping. These materials can be used as electrolyte for battery/solid oxide fuel cell due to their good conductivity (~0.12 Scm−1) at 450 °C.

Abstract
Diabetes is an increasing challenge for low- and middle-income countries (LMIC) and access to HbA1c testing is limited. HbA1c, a measure of glycaemic control averaged over 3 months, provides both clinicians and policymakers with a tool to identify the risk of long-term diabetes comorbidity. We describe the steps used to implement standardised testing in Guyana South America and the initial results according to a locally developed protocol as part of a country-wide project to improve the care of people with all forms of diabetes The steps identified include: a standardised method traceable to a recognized international reference standard, participation in a quality control cycle with an international reference laboratory, a clinical pathway for testing to reduce inappropriate use and minimize resource wastage, training of technicians in operation and maintenance of equipment, identification of a suitable space with constant power supply, a reliable procurement system, education of healthcare professionals on interpretation and follow-up of results and feedback of programme results to improve clinical practice. Some steps for implementation of the national HbA1c testing program were initiated better than others. Initial unreliability of the service undermined confidence in the system. Failure to follow the testing protocol led to some patients being tested too soon and others too late. Cost of reagents was about 5.60 USD/test. We trained 340 people in diabetes care and knowledge was improved but were unable to assess whether it was appropriately applied. Over one third of people tested in the 30-70 age group had an HbA1c over 9% (75 mmol/mol) and this did not improve over the 5 years of testing. Despite the difficulties we think our unique experience of implementation of a nationwide HbA1c testing programme has important lessons for other LMICs.

Abstract
The following study was designed to find out the association of the mid-upper arm body composition and body mass index (BMI) with depressive symptoms among the old age home based (group 1) and family based elderly (group 2) subjects. In group 1 elderly males, 51.5% were showing mild depressive symptoms and 17% were showing moderate to severe depressive symptoms. On the other hand, among group 2 elderly males, prevalence of mild depressive symptoms was in 27% and moderate to severe depressive symptoms was in 4.5% of the subjects. Among elderly with and without depressive symptoms, BMI, waist-hip ratio (WHR), arm muscle circumference (AMC), arm muscle area (AMA), arm fat area (AFA), fat mass (FM), muscle mass and bone mass were significantly (p < 0.01) lesser among group 1 as compared to group 2. Among group 1, the AFA (R2 change = 0.178), AMC (R2 change = 0.035), AMA (R2 change = 0.032), FM (R2 change = 0.022) and muscle mass (R2 change = 0.019) have highest contribution to the variance of depressive symptoms. On the other hand, BMI (R2 change = 0.04) and WHR (R2 change = 0.03) had the highest, though small, contribution to the variance of depressive symptoms among group 2. The upper arm body composition indices were better indicator of depressive symptoms in group 1, and BMI and WHR were better indicators of depressive symptoms in group 2. Therefore, among group 1 subjects, the upper arm body composition indices prove to be better regular health monitoring indices as compared to traditionally used BMI and WHR.

Abstract
Small RNAs (sRNAs) are 20–30-nucleotide-long, regulatory, noncoding RNAs that induce silencing of target genes at the transcriptional and posttranscriptional levels. They are key components for cellular functions during plant development, hormone signaling, and stress responses. Generated from the cleavage of double-stranded RNAs (dsRNAs) or RNAs with hairpin structures by Dicer-like proteins (DCLs), they are loaded onto Argonaute (AGO) protein complexes to induce gene silencing of their complementary targets by promoting messenger RNA (mRNA) cleavage or degradation, translation inhibition, DNA methylation, and/or histone modifications. This mechanism of regulating RNA activity, collectively referred to as RNA interference (RNAi), which is an evolutionarily conserved process in eukaryotes. Plant RNAi pathways play a fundamental role in plant immunity against viruses and have been exploited via genetic engineering to control disease. Plant viruses of RNA origin that contain double-stranded RNA are targeted by the RNA-silencing machinery to produce virus-derived small RNAs (vsRNAs). Some vsRNAs serve as an effector to repress host immunity by capturing host RNAi pathways. High-throughput sequencing (HTS) strategies have been used to identify endogenous sRNA profiles, the “sRNAome”, and analyze expression in various perennial plants. Therefore, the review examines the current knowledge of sRNAs in perennial plants and fruits, describes the development and implementation of RNA interference (RNAi) in providing resistance against economically important viruses, and explores sRNA targets that are important in regulating a variety of biological processes.

Abstract
Variety of implant materials have been employed in various disciplines of medical science depending on the requirement of a particular application. Metals, alloys, ceramics, and polymers are the commonly used biomaterials. The main focus of this study is to review the various structural and microstructural properties of titanium and titanium based alloys used as orthopaedic implants. Orthopaedic implants need to possess certain important qualities to ensure their safe and effective use. These properties like the biocompatibility, relevant mechanical properties, high corrosion and wear resistance and osseointegration are summarized in this review. Various attempts to improve upon these properties like different processing routes, surface modifications have also been inculcated in the paper to provide an insight into the extent of research and effort that has been put into developing a highly superior titanium orthopaedic implant.

Abstract
A 2nd generation roof bolter canopy air curtain (CAC) design was tested by National Institute for Occupational Safety and Health (NIOSH) at a Midwestern underground coal mine. During the study, the roof bolter never operated downwind of the continuous miner. Using a combination of personal Data Rams (pDR) and gravimetric samplers, the dust control efficiency of the roof bolter CAC was ascertained. Performance evaluation was determined using three methods: (1) comparing roof bolter operator concentrations underneath the CAC to roof bolter concentrations outside the CAC, (2) comparing roof bolter operator concentrations underneath the CAC to the concentrations at the rear of the bolter, and finally, (3) using the gravimetric data directly underneath the CAC to correct roof bolter operator concentrations underneath the CAC and comparing them to the concentrations at the rear of the bolter. Method 1 dust control efficiencies ranged from -53.9% to 60.4%. Method 2 efficiencies ranged from -150.5% to 52.2%, and Method 3 efficiencies ranged from 40.7% to 91%. Reasons for negative and low dust control efficiencies are provided in this paper and include: incorrect sampling locations, large distance between CAC and operator, and contamination of intake air from line curtain. Low dust concentrations encountered during the testing made it difficult to discern whether differences in concentrations were due to the CAC or due to variances inherent in experimental dust measurement. However, the analyses, especially the Method 3 analysis, show that the CAC can be an effective dust control device.

Abstract
Due to the successful application of roof bolter canopy air curtains (CACs) to protect roof bolter operators from high levels of coal mine respirable dust, a shuttle car CAC is currently being developed. Since a shuttle car consistently trams from the continuous miner to the feeder and back at a speed up to 9.66 kph (6 mph) or 2.68 m/s (528 fpm), it is thought that the shuttle car may encounter very high air velocities (mine ventilation air velocity + max shuttle speed (2.68 m/s (528 fpm)). Past research and preliminary lab testing showed that CAC protection in high interference air velocities is difficult to achieve. Therefore, testing was conducted at a Midwestern US coal mine to determine the air velocities their shuttle car actually encounters. This mine used ram dump cars as their shuttle cars. Results showed that coal mine dust exposure is generally very low at the feeder and when tramming. Elevated concentrations are encountered at the ram dump car operator position when the car is being loaded by the continuous miner. Recorded air velocities while tramming did not reach the max air velocity of mine ventilation air velocity + 2.68 m/s (528 fpm) calculated as 3.32 m/s (653 fpm). High velocities, while encountered, were of low frequency and associated with low respirable coal mine dust concentrations. Therefore, using this new information, designing the shuttle car CAC for maximum interference air velocity may not be as important as previously thought.

Abstract
There is currently scarce knowledge of the immunological profile of patients with latent autoimmune diabetes mellitus in the adult (LADA) when compared with healthy controls (HC) and patients with classical type 1 diabetes (T1D) and type 2 diabetes (T2D). The objective of this study was to investigate the cellular immunological profile of LADA patients and compare to HC and patients with T1D and T2D. All patients and age‐matched HC were recruited from Uppsala County. Peripheral blood mononuclear cells were isolated from freshly collected blood to determine the proportions of immune cells by flow cytometry. Plasma concentrations of the cytokine interleukin (IL)‐35 were measured by enzyme‐linked immunosorbent assay (ELISA). The proportion of CD11c+CD123– antigen‐presenting cells (APCs) was lower, while the proportions of CD11c+CD123+ APCs and IL‐35+ tolerogenic APCs were higher in LADA patients than in T1D patients. The proportion of CD3–CD56highCD16+ natural killer (NK) cells was higher in LADA patients than in both HC and T2D patients. The frequency of IL‐35+ regulatory T cells and plasma IL‐35 concentrations in LADA patients were similar to those in T1D and T2D patients, but lower than in HC. The proportion of regulatory B cells in LADA patients was higher than in healthy controls, T1D and T2D patients, and the frequency of IL‐35+ regulatory B cells was higher than in T1D patients. LADA presents a mixed cellular immunological pattern with features overlapping with both T1D and T2D.

Abstract
Abstract
Background: Axillary lymph node dissection (ALND) is performed for axillary lymph nodal metastasis. Major complication of ALND is lymphedema. Lymphedema is a morbid condition associated with impaired activities of daily life and deterioration in quality of life (QOL). Olszewski et al (Lymphology. 2005 Jun;38(2):66–80) have shown that low-grade staphylococcal infection is a risk factor for lymphedema. Hence, we embarked upon a randomised controlled trial with non-inferiority hypothesis to evaluate efficacy of injection Benzathine penicillin in preventing breast cancer related lymphedema.
Methods: In this 2 group, open label, parallel design randomized controlled trial; patients undergoing ALND for breast cancer were included. Patients were randomized using block randomization to either injection Benzathine penicillin group or in control group. Patients in the penicillin group received injection Benzathine penicillin 1.2 million units as deep intramuscular injection after antibiotic sensitivity testing at intervals of 3 weeks. Primary endpoint was development of lymphedema at 6 months follow up. Analyses were done on an intention to treat basis. Lymphedema was defined as increase in >200ml of volume on water displacement method and or increase in arm circumference of >2cm from pre surgery values (Lancet Oncol. 2013 May 1;14(6):500–15).
Findings: Between July 2016 and December 2017, 83 ladies were randomly allocated, 40 in the penicillin group and 43 in control group. At 6 months follow up; a total of 15 (18.07%) patients had lymphedema. Out of them 5 patients were in penicillin group and 10 in the control group. Cellulitis was seen in 2/3rd of patients (10 out of 15) having lymphedema. The relative risk of cellulitis in penicillin group was 0.119 with 95% CI of (0.016-0.901) and prevented fraction of 0.881. Other factors like radiotherapy, type of surgery for primary tumor, extent of axillary dissection and type of chemotherapy were comparable in both groups. None of the patients receiving penicillin have any adverse effect or allergic reaction to the drug during the study period.

Conclusion: Penicillin administration in patients undergoing axillary lymph node dissection is safe and significantly reduces risk of lymphedema and cellulitis.
Novelty: This is the first randomised trial demonstrating the benefit of long term administration of penicillin in reducing lymphedema and cellulitis.

Abstract
OBJECTIVE The objective of the study was to evaluate the effect of high-dose chemotherapy (HDC) with peripheral blood stem cell support (PBSCS) on survival of patients with gestational trophoblastic neoplasia (GTN) with either refractory choriocarcinomas or a poor-prognosis placental site/epithelioid trophoblastic tumours (PSTT/ETTs). METHODS Databases of two referral centres for gestational trophoblastic disease were searched, and 32 patients treated with HDC between 1994 and 2015 were identified. Tissue samples were retrieved for genetic evaluation. Cox regression analyses were performed to identify possible predictors of overall survival (OS). RESULTS HDC induced a sustained complete response in 7 patients. Overall, 41% (13/32) of the patients remained disease free after HDC with or without additional treatment. Patients who survived had much lower human chorionic gonadotropin (hCG) values (all ≤12 IU/L) before and after HDC than those who died of disease. Univariable Cox regression analysis demonstrated that hCG >12 IU/L before or after HDC, International Federation of Gynaecology and Obstetrics (FIGO) stage II-IV and presence of metastases at the time of diagnosis were significantly associated with adverse OS. However, only hCG values before HDC remained significant in a multivariable model (p < 0.001). Five of 11 (45%) patients with PSTT/ETT presenting ≥48 months after antecedent pregnancy and 6 of 14 (43%) patients with refractory choriocarcinoma were in remission. Three treatment-related deaths occurred. CONCLUSIONS Despite 3 treatment-induced deaths, HDC with PBSCS appears to be active in salvaging selected patients with poor-prognosis PSTT/ETTs and refractory choriocarcinomas. Low hCG values before HDC seems a beneficial predictor of OS and may suggest that HDC acts more like a consolidation therapy.

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