Abstract
Intraplacental choriocarcinoma is a rare tumour, with approximately 62 reported cases. It may manifest as a spectrum of disease ranging from an incidental lesion diagnosed on routine placental examination to disseminated maternal and/or neonatal disease. In this case series, we presented two rare cases of intraplacental choriocarcinoma with extremely varied clinical presentations. The extremely varied clinical presentations of both patients described in the case series complicated the process of arriving at the diagnosis. In both cases, subsequent investigations showed no maternal or neonatal metastasis, and maternal serum beta-hCG levels downtrended with conservative management. We aim to highlight the importance of performing a detailed physical examination and evaluation of the patient and multidisciplinary management with oncology opinion. A detailed examination of the placenta should also be considered when faced with obstetric complications so that early diagnosis and the required management can be executed in a prompt fashion.

Abstract
PURPOSE/OBJECTIVE(S) Despite maximal treatment, nearly all patients with grade 4 gliomas develop recurrent disease. Treatment options for these patients are limited and overall survival is poor. Re-irradiation may be considered in certain patients, though risk of side effects often limits the effective dose able to be delivered. Pulsed reduced dose rate (PRDR) radiation is a treatment technique that reduces effective dose rate and increases treatment time allowing for intrafraction repair. Here, we report safety and efficacy of PRDR re-irradiation for recurrent grade 4 gliomas. MATERIALS/METHODS We performed a retrospective review of patients treated with PRDR between 2001 and 2022. Patients were treated with reduced dose rate radiation delivered in 0.2 Gy pulses every 3 minutes in 2 Gy daily fractions. Both 3D conformal and step and shoot IMRT radiation plans were utilized. Toxicities were evaluated based on Common Terminology Criteria for Adverse Events (CTCAE) v5.0 criteria. Kaplan Meier analysis was used to calculate overall survival (OS). Cox regression analysis was performed for multivariate analysis. RESULTS A total of 168 grade 4 glioma patients treated with PRDR re-irradiation were identified. The median age was 55 years old. The median initial radiation dose was 60 Gy (range 36 Gy - 72 Gy) and the median PRDR dose was 54 Gy (range 37.5 - 60 Gy). Seventy percent of patients received systemic therapy for recurrent disease prior to PRDR, while 30% received PRDR as first treatment for recurrent disease (or following re-resection without other treatment). The median survival following PRDR was 6.3 months. Multivariate analysis showed time since initial radiation of 14+ months (HR 0.66, p = 0.005, 95% CI 0.44 - 0.98), pre-PRDR use of steroids (HR 1.78, p = 0.005, 95% CI 1.2 - 2.66), and Karnofsky performance status of 70 or greater to be a significant predictor of survival (HR = 0.6, p = 0.008, 95% CI 0.44 - 0.98). No grade 4 or 5 toxicity was noted. Grade 3 new onset seizures was noted in 6% of patients, all subsequently controlled with medication. The most common grade 1-2 side effect after treatment was fatigue. CONCLUSION In this large, retrospective cohort, PRDR re-irradiation for recurrent grade 4 gliomas was well tolerated with low rates of grade 3 toxicity. Overall survival outcomes were encouraging, especially in heavily pre-treated patients. Prospective studies are ongoing to further evaluate the efficacy of PRDR for recurrent glioma treatment.

Abstract
Foreign body upper aerodigestive tract is a common presentation but foreign body migrating into retropharyngeal space is not only uncommon, but its management also differs and is challenging too. Here we present a case of a foreign body migrating into the retropharyngeal space which was removed intraorally. A 28- year old male patient presented with complaints of pain while swallowing following consumption of sausage and pork two days earlier to the onset of symptoms. X-Ray Neck AP and lateral view were done which revealed a thin metallic foreign body at the level of the T4 vertebra. Upper gastrointestinal endoscopy and rigid esophagoscopy were done in which a foreign body was not visualized in the esophageal lumen. NCCT neck was done which gave precise location and was removed intraorally with the patient in Rose position. A repeat x-ray was done on the 5th day which revealed no foreign body, the patient was discharged on the 7th day. Although the upper aerodigestive tract foreign body is common, foreign body migrating to the posterior pharyngeal wall or into the retropharyngeal space is not common and it is difficult to remove a migrated foreign body many cases requiring open procedures, thoracoscopy, thoracotomy.

Abstract
OBJECTIVES To validate prospectively transvaginal ultrasound assessment of the lower uterine segment (LUS) scar at the time of first-trimester screening in women with previous Cesarean section (CS) and to determine its feasibility and accuracy in stratifying women according to the risk for placenta accreta spectrum (PAS) disorder. METHODS Women with a history of CS were recruited between 11 + 0 and 13 + 6 weeks' gestation and underwent LUS scar assessment using transvaginal ultrasound. A standardized midsagittal plane, which included the cervicoisthmic canal (CIC), the uterine scar and the placental site, was obtained. The scar was described in terms of its size (narrow or dehiscent) and its location in relation to the CIC (within or above), with each LUS scar classified into one of four groups based on these features. Placental location was assessed and classified as high- or low-lying. Women were stratified according to the risk of PAS, based on the relationship between the scar location and placental site. Women were considered high risk when the scar was above the CIC and the placenta was low-lying (i.e. when the placenta was overlying an exposed scar) and low risk when the scar was within the CIC and/or the placenta was high. High-risk patients were followed up at 20 weeks and 28-30 weeks for the development of PAS. Maternal demographics, detailed obstetric history and obstetric outcome were collected. RESULTS First-trimester transvaginal ultrasound was offered to 535 women with prior CS during the study period. A LUS scar was visualized in 79.9% (401/502) of those who agreed to undergo the examination. At this scan, the LUS scar was above the CIC in 9.0% (36/401) of women, but only 5.7% (23/401) additionally had a low-lying placenta overlying the scar. Of these 23 high-risk women, two were found to have PAS on the mid-trimester screening scan and one was noted to have placental adherence during evacuation following mid-trimester termination of pregnancy. On the first-trimester scan, 94.3% (378/401) of women were at low risk of PAS. This screening protocol yielded a positive likelihood ratio of 21.33 (95% CI, 13.02-34.96), sensitivity of 100% (95% CI, 29.24-100%), specificity of 95.31% (95% CI, 92.39-97.35%), positive predictive value of 16.7% (95% CI, 5.8-39.2%) and negative predictive value of 100% (95% CI, 98.4-100%). On multivariable regression analysis performed to identify confounding variables associated with a LUS scar above the CIC, only maternal body mass index ≥ 30 kg/m2 was significant (odds ratio (OR), 2.42 (95% CI, 1.04-5.39); P = 0.03). Although there was a trend towards an increased risk of a LUS scar above the CIC in women with prior elective prelabor CS (OR, 1.72 (95% CI, 0.80-3.68)), this association did not reach statistical significance. CONCLUSIONS Routine transvaginal ultrasound assessment of the location of the LUS scar and placenta at the time of first-trimester screening between 11 + 0 and 13 + 6 weeks' gestation in women with prior CS is a feasible and effective tool to identify those at risk of subsequent development of PAS disorder. A finding of placental implantation over an exposed LUS scar seems to be cardinal in predicting the risk of PAS disorder in women with prior CS, with an excellent negative predictive value. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
BACKGROUND AND PURPOSE Infantile hemangiomas are common lesions in the pediatric population; in rare cases, an infantile hemangioma can be detected along the neural axis. The purposes of our study included determination of the incidence, location, and imaging appearance of neuroaxial infantile hemangiomas and their syndromic association. We also assessed additional features of cerebral and cardiovascular anomalies that may be associated with neuroaxial lesions. MATERIALS AND METHODS A retrospective cohort study was performed, searching the radiology database for patients with segmental infantile hemangiomas referred for assessment of possible hemangioma syndromes. We retrospectively reviewed brain and spine MR imaging studies, with particular attention paid to neuroaxial vascular lesions, as well as the relevant clinical data. Neuroaxial hemangioma imaging findings were described, and comparison of segmental cutaneous infantile hemangioma location with the imaging findings was performed in patients with confirmed hemangioma syndromes and in patients with isolated skin infantile hemangioma. RESULTS Ninety-five patients with segmental infantile hemangioma were included in the study, 42 of whom had a hemangioma syndrome; of those, 41 had posterior fossa brain malformations, hemangioma, arterial lesions, cardiac abnormalities, and eye abnormalities (PHACE) syndrome and 1 had diffuse neonatal hemangiomatosis. Neuroaxial involvement was detected in 20/42 patients (48%) with hemangioma syndromes and in no subjects with isolated segmental infantile hemangioma (P < .001). The most common intracranial hemangioma location was within the ipsilateral internal auditory canal (83%). CONCLUSIONS Many pediatric patients with segmental infantile hemangioma in the setting of hemangioma syndromes, especially those with PHACE, had neuroaxial hemangiomas. This finding may potentially lead to requiring additional clinical evaluation and management of these patients.

Abstract
BACKGROUND The intrauterine environment is a key determinant for long-term health outcomes. Adverse fetal environments, such as maternal diabetes, obesity and placental insufficiency are strongly associated with long-term health risks in children. Little is known about differences in fetal cardiac output hemodynamics of diabetic mothers (DM) vs. non-diabetic mothers (NDM). Our study aims to investigate the left-sided, right-sided, and combined cardiac output (CCO) in fetuses of DM vs. NDM. METHODS Retrospective data were collected in fetuses of DM (N = 532) and NDM (103) at mean gestational age 24 weeks. Examination included 2D echo and pulse wave Doppler. Wilcoxon rank sum tests and Chi-square tests were used to test for distribution difference of maternal and fetal continuous and categorical measures respectively between DM and NDM. Intraclass correlation coefficients were calculated to assess intra-observer reliability of fetal cardiac measurements. RESULTS DM mothers had higher mean weight (89.7±22.2 kg) than NDM (76.8±19.8 kg), p < 0.0001 and higher mean BMI (33.4±7.5) than NDM (28.3±5.8), p < 0.0001. C-section delivery occurred in 66% of DM vs. 35% of NDM fetuses. Fetuses of DM mothers had significantly larger semilunar valve diameter, higher left ventricular (LV) output, higher combined cardiac output and lower right ventricle /left ventricle ratio compared to NDM. CONCLUSION The greater CCO (adjusted for fetal weight), left sided cardiac output in the fetuses of DM, compared to NDM, represent differences in cardiac adaptation to the diabetic environment.

Abstract
BACKGROUND Levonadifloxacin is a novel broad-spectrum anti-MRSA agents belonging to the benzoquinolizine subclass of quinolone. It is developed for oral or intravenous administration for the treatment of infections caused by Gram-positive organisms including methicillin-resistant Staphylococcus aureus (MRSA). OBJECTIVES To establish the non-inferiority of levonadifloxacin compared with linezolid for the treatment of acute bacterial skin and skin structure infections (ABSSSI) and to compare the safety of the two antimicrobials. SUBJECTS AND METHODS This was a Phase 3, multicentre, randomized, open-label, active- comparator study with 500 subjects. Oral levonadifloxacin 1000 mg was compared with oral linezolid 600 mg whereas IV levonadifloxacin 800mg was compared with IV linezolid 600 mg, each treatment was administered twice daily for 7-10 days. Non-inferiority was evaluated by comparing oral levonadifloxacin to oral linezolid and IV levonadifloxacin to IV linezolid for overall clinical response at TOC (Test of Cure) Visit. RESULTS The clinical cure rates observed at the TOC in the mITT (modified Intent to treat) populations for levonadifloxacin was numerically higher compared to linezolid in the IV sub-group [(91.0% verses 87.8%); treatment difference of 3.2% (95%CI, -4.5 to 10.9)] and in the oral sub-group (95.2% versus 93.6%); treatment difference of 1.6 % [95%CI, -4.2 to 7.3]). As the lowerbound of the 95% CI around the treatment difference was greater than -15% for both subgroups, the primary objective of the study was met. Therefore, both IV levonadifloxacin and oral levonadifloxacin were non-inferior to IV linezolid and oral linezolid, respectively. The majority of subjects in the micro-ITT population had a baseline infection caused by S. aureus with approximately 30% of subjects having MRSA. Levonadifloxacin (IV and oral) had a higher clinical cure rate at TOC for MRSA patients compared with linezolid (IV and oral), (95.0% vs. 89.3% respectively). Levonadifloxacin showed evidence of favourable clinical and microbiological efficacy in subjects with concurrent bacteraemia as well as in subjects with diabetes including diabetic foot infections caused by Gram-positive pathogens including MRSA. Pharmacokinetic analysis showed that bioavailability of oral levonadifloxacin was 90% and similar pharmacokinetic profile of levonadifloxacin by both routes provide an option for IV to oral switch for the treatment of subjects. Incidences of treatment-emergent adverse events (TEAEs) were similar between treatment groups and between IV (20.8% vs. 22.4%, for levonadifloxacin and linezolid, respectively) and oral therapy (16.0% vs. 13.5%, respectively), There were no SAEs or deaths related to study drug and the majority of the AEs observed were mild in nature. Overall, the administration of both IV and oral levonadifloxacin was well-tolerated in subjects with ABSSSI. CONCLUSIONS The results demonstrate that IV and oral levonadifloxacin therapy has excellent clinical activity against MRSA and offers advantage compared to other quinolones which generally lack MRSA coverage. Levonadifloxacin is safe and well tolerated in the treatment of ABSSSI caused by Gram -positive pathogens including MRSA as well as non-inferior to IV and oral linezolid, respectively. Similar pharmacokinetic profile of IV and oral levonadifloxacin provides an option for IV to oral switch for the treatment of subjects. Both oral and IV levonadifloxacin have recently been granted approval in India for the treatment of ABSSSI including diabetic foot infections and concurrent bacteraemia in adults (18 years of age or older).

Abstract
Chronic pain causes significant suffering, limitation of daily activities and reduced quality of life. Infection from COVID-19 is responsible for an ongoing pandemic that causes severe acute respiratory syndrome, leading to systemic complications and death. Led by the World Health Organization, healthcare systems across the world are engaged in limiting the spread of infection. As a result, all elective surgical procedures, outpatient procedures and patient visits, including pain management services, have been postponed or cancelled. This has affected the care of chronic pain patients. Most are elderly with multiple comorbidities, which puts them at risk of COVID-19 infection. Important considerations that need to be recognised during this pandemic for chronic pain patients include: ensuring continuity of care and pain medications, especially opioids; use of telemedicine; maintaining biopsychosocial management; use of anti-inflammatory drugs; use of steroids; and prioritising necessary procedural visits. There are no guidelines to inform physicians and healthcare providers engaged in caring for patients with pain during this period of crisis. We assembled an expert panel of pain physicians, psychologists and researchers from North America and Europe to formulate recommendations to guide practice. As the COVID-19 situation continues to evolve rapidly, these recommendations are based on the best available evidence and expert opinion at this present time and may need adapting to local workplace policies.

Abstract
Abstract
Background
Early identification of patients at risk for atrial fibrillation (AF) is desirable to prevent its development and complications. Clinical predictors have been recognized but need refinement to improve predictability. We evaluated whether severity of left atrial enlargement (LAE) added to a scoring system (CHA2DS2VASC) in an unselected non-AF population improves risk stratification for incident AF.
Purpose
To assess the incremental benefit of LAE severity added to CHA2DS2VASc in predicting future AF in non-AF patients.
Methods
From 2012–2017, consecutive adult patients with an echocardiogram and no prior AF were identified. CHA2DS2VASc was used to define baseline AF risk, and the incremental risk of AF with addition of LAE was assessed through increased LA volume index (LAVI; moderate 42–48 ml/m2, severe >48 ml/m2). To quantify improvement in risk prediction, logistic regression model was fitted and odds ratios (OR) and ROC curves obtained.
Results
Out of 155,597 patients with no prior AF, 13.8% developed AF over 1.5±1.3 years. OR for AF with CHA2DS2VASc was 1.68 (95% CI 1.66–1.69). With addition of moderately or severely increased LAVI to the model, OR for AF increased to 2.3 (2.2–2.5) and 3.8 (3.6–4.0), respectively. ROC analysis showed c-statistics of 0.66 with CHA2DS2VASc, 0.63 with LAVI, and 0.71 with incorporation of both (Fig).
AF CHAD score
Conclusion(s)
In non-AF patients, predictability for future AF can be improved by using clinical factors (CHA2DS2VASc) and increased LAVI. This information may guide closer monitoring and initiation of therapies to prevent progression to AF or stroke.

Abstract
BACKGROUND AND PURPOSE The purpose of the study is to characterize diffusion tensor imaging indices in the developing spinal cord, evaluating differences based on age and cord region. Describing the progression of DTI indices in the pediatric cord increases our understanding of spinal cord development. MATERIALS AND METHODS A retrospective analysis was performed on DTI acquired in 121 pediatric patients (mean, 8.6 years; range, 0.3-18.0 years) at Monroe Carell Jr. Children's Hospital at Vanderbilt from 2017 to 2018. Diffusion-weighted images (15 directions; b = 750 s/mm2; slice thickness, 5 mm; in-plane resolution, 1.0 × 1.0 mm2) were acquired on a 3T scanner in the cervicothoracic and/or thoracolumbar cord. Manual whole-cord segmentation was performed. Images were masked and further segmented into cervical, upper thoracic, thoracolumbar, and conus regions. Analyses of covariance were performed for each DTI-derived index to investigate how age affects diffusion across cord regions, and 95% confidence intervals were calculated across age for each derived index and region. Post hoc testing was performed to analyze regional differences. RESULTS Analyses of covariance revealed significant correlations of age with axial diffusivity, mean diffusivity, and fractional anisotropy (all, P < .001). There were also significant differences among cord regions for axial diffusivity, radial diffusivity, mean diffusivity, and fractional anisotropy (all, P < .001). CONCLUSIONS This research demonstrates that diffusion evolves in the pediatric spinal cord during development, dependent on both cord region and the diffusion index of interest. Future research could investigate how diffusion may be affected by common pediatric spinal pathologies.

Abstract
We studied the efficacy of a range of doses of dexamethasone for prevention of postoperative nausea and vomiting following strabismus repair in children in a hospital-based, prospective, double-blinded, randomized, placebo-controlled trial. Two hundred and ten children were randomized to receive either dexamethasone in one of four dosages: 50 μg/kg (Group 1), 100 μg/kg (Group 2), 200 μg/kg (Group 3) and 250 μg/kg (Group 4) or normal saline (Group 5) prior to corrective surgery for strabismus. Anaesthesia was standardized and included nitrous oxide, pethidine, intubation and the use of muscle relaxant and reversal with neostigmine. Postoperative nausea and vomiting were evaluated in epochs of 0-2 hours, 2-6 hours and 6-24 hours after surgery. Parent satisfaction was assessed 24 hours after surgery and the operated eye was examined for wound infection and delayed healing one week later. Dexamethasone was effective in preventing nausea and vomiting after strabismus repair: 57.1% children in Group 1, 42.9% in Group 2, 52.4% in Group 3, and 59.5% in Group 4 were free from postoperative nausea and vomiting compared with 7.1% in placebo group. The lowest dose of 50 μg/kg was as efficacious as the higher dosages of dexamethasone during the 24 hours studied. Of the children who developed postoperative nausea and vomiting, those who received dexamethasone had significantly fewer episodes than those in the placebo group. We conclude that dexamethasone 50 μg/kg is effective for the prevention of postoperative nausea and vomiting following strabismus repair in children.

Abstract
Chronic exposure of humans to inorganic arsenic as a potential risk for the incidence of diabetes has received wide attention. However, the biological mechanism through which arsenic plays a role in the development of diabetes is still being evaluated. One of the hallmark of diabetes is the β-cell dysfunction followed by the changes in the insulin secretion. Pancreatic duodenal homeobox 1 (PDX1) has been widely recognized to play crucial role in the β-cell development, survival and its regulation of insulin gene expression. Many of the arsenic mediated cellular affects have been shown to be regulated by miR-2909 in vitro. Our present study provides evidence to reveal that arsenic affects miR-2909 expression in the pancreatic β-cell and this novel miRNA regulates PDX1 transcriptional expression indirectly through genes coding for c-Jun, MafA, PI3K and directly at the translational level by targeting the PDX1 mRNA. We provide further evidence for this miR-2909 RNomics in pancreatic tissue obtained from NOD mice where the expression of miR-2909 was high compared to the control mice. Keeping in view the fact that arsenic is known to cause β-cell dysfunction and most of the cellular effects of arsenic have been shown to be mediated through miR-2909 RNomics, our study revealed that arsenic employs miR-2909 (at low doses) and c-Jun (at high doses) to down regulate PDX1 in order to cause β-cell dysfunction leading to diabetic state.

Abstract
This study investigated the effect of various intermittent aeration (IA) cycles on organics and nutrient removal, and microbial communities in an integrated fixed-film activated sludge (IFAS) reactor treating municipal waste water. Average effluent biological oxygen demand (BOD), chemical oxygen demand (COD), total suspended solids, total nitrogen (TN) and total phosphorus (TP) values were noted as 20, 50, 30, 12 and 1.5 mgL-1, respectively, in continuous aeration mode. A total of four operational conditions (run 1, continuous aeration; run 2, 150/30 min aeration on/off time; run 3, 120/60 min aeration on/off time and run 4, 90/60 min aeration on/off time) were investigated in IFAS reactor assessment. Among the all examined IA cycles, IA phase 2 gave the maximum COD and BOD removals with values recorded as 97% and 93.8%, respectively. With respect to nutrient removal (TN and TP), IA phase 1 was found to be optimum. Pathogen removal efficiency of present system was recorded as 90-95% during the three phases. With regard to settling characteristics, pilot showed poor settling during IA schedules, which was also evidenced by high sludge volume index values. Overall, IA could be used as a feasible way to improve the overall performance of IFAS system.

Abstract
The global occurrence of prostate cancer with a range of patient outcome has prompted various investigators to explore novel molecular biomarkers that can precisely detect and track this type of cancer severity. Several studies suggest that micro-RNAs have emerged to act as a new largely unexplored class of biomarkers because of their inherent stability, resilience and recruitment into exosomes present in various human body fluids. With this study, we aim to reveal the nature of urinary-exosomal miR-2909 & miR-615-3p recruitment in patients suffering from either prostate cancer (n=90) or bladder cancer (n=60) as compared to that in either prostate disease-control subjects having benign prostate hyperplasia (n=10) or healthy subjects (n=50). Unlike miR-615-3p, the urinary- exosomal miR-2909 recruitment was not only observed conspicuously in subjects having prostate cancer in comparison to bladder cancer but also the extent of urinary exosomal miR-2909 recruitment showed characteristic variation as a function of prostate cancer aggressiveness as compared to that of either urinary- exosomal miR-615-3p level or existing widely recognised serum prostate specifics antigen (PSA) biomarker of this cancer. In summary, we propose that the extent of urinary exosomal miR-2909 recruitment may provide a potential non-invasive candidate diagnostic marker for the detection of prostate cancer and its aggressiveness.

Abstract
In the present study, the effect of three intermittent aeration (IA) cycles on treatment performance and microbial diversity was investigated in an integrated fixed film activated sludge (IFAS) reactor treating municipal wastewater. The results showed that IA strategies were able to achieve efficient removal of organics and nitrogen ranging between 90 and 95% and 70 and 80%, respectively, however the phosphorus removal was found to be inversely proportional to the duration of aeration off time in each IA cycle. The microscopic analysis revealed that the suspended and attached biomass had compact morphology and open floc structure, respectively. For each gram of volatile suspended solids, 165 and 148 mg of extracellular polymeric substances (EPS) were extracted from attached and suspended biomass, respectively, constituting carbohydrates (∼24%), proteins (∼31%), humic acids (∼28%), DNA (∼2%) and unknown substances (∼12%). The microbial diversities of suspended biomass in IFAS reactor were investigated using culture-dependent approach, which confirmed the presence of Clostridium spp., Pseudomonas spp., Bacillus spp., Escherichia coli spp., Nitrosococcus spp., Streptococcus spp., Acinetobacter spp., Betaproteobacteria outliers, Klebsiella pneumoniae, Klebsiella aerogenes, Serratia marcescens, Micrococcus, Proteus vulgaris spp., Actinomycetes spp., and Actinobacteria including Micromonospora spp. and Streptomyces spp. Molecular tools for diversity analyses were used for ammonia and nitrite oxidizer identification, such as Nitrospira and Nitrosococcus species. Denitrifiers include the species of Pseudomonas, Betaproteobacteria and Flavobacterium. Acinetobacter, Betaproteobacteria and Gammaproteobacteria were responsible for the phosphorus removal in the present system. Overall, the system performed efficiently showing Proteobacteria (59%), Acinetobacter (12%) and Bacteroidetes (11%) as the dominant bacterial groups. However, the dominance of the bacterial diversity varied with the IA cycle time numerating the maximum percentage of bacterial species during IA1 phase i.e. 2.5 h aeration/0.5 h non-aeration.

Abstract
Both intracellular and extracellular heat shock protein-90 (Hsp90) family proteins (α and β) have been shown to support tumour progression. The tumour-supporting activity of the intracellular Hsp90 is attributed to their N-terminal ATPase-driven chaperone function. What molecular entity determines the extracellular function of secreted Hsp90 and the distinction between Hsp90α and Hsp90β was unclear. Here we demonstrate that CRISPR/Case9 knocking out Hsp90α nullifies tumour cells' ability to migrate, invade and metastasize without affecting the cell survival and growth. Knocking out Hsp90β leads to tumour cell death. Extracellular supplementation with recombinant Hsp90α, but not Hsp90β, protein recovers tumourigenicity of the Hsp90α-knockout cells. Sequential mutagenesis identifies two evolutionarily conserved lysine residues, lys-270 and lys-277, in the Hsp90α subfamily that determine the extracellular Hsp90α function. Hsp90β subfamily lacks the dual lysine motif and the extracellular function. Substitutions of gly-262 and thr-269 in Hsp90β with lysines convert Hsp90β to a Hsp90α-like protein. Newly constructed monoclonal antibody, 1G6-D7, against the dual lysine region of secreted Hsp90α inhibits both de novo tumour formation and expansion of already formed tumours in mice. This study suggests an alternative therapeutic approach to target Hsp90 in cancer, that is, the tumour-secreted Hsp90α, instead of the intracellular Hsp90α and Hsp90β.

Abstract
Nitrogen (N) use in agriculture substantially alters global N cycle with the short- and long-term effects on global warming and climate change. It increases emission of nitrous oxide, which contributes 6.2%, while carbon dioxide and methane contribute 76% and 16%, respectively of the global warming. However, N causes cooling due to emission of NOx, which alters concentrations of tropospheric ozone and methane. NOx and NH3 also form aerosols with considerable cooling effects. We studied global temperature change potential (GTP) of N use in agriculture. The GTP due to N2O was 396.67 and 1168.32 Tg CO2e on a 20-year (GTP20) and 439.94 and 1295.78 Tg CO2e on 100-year scale (GTP100) during years 1961 and 2010, respectively. Cooling effects due to N use were 92.14 and 271.39 Tg CO2e (GTP20) and 15.21 and 44.80 Tg CO2e (GTP100) during 1961 and 2010, respectively. Net GTP20 was 369.44 and 1088.15 Tg CO2e and net GTP100 was 429.17 and 1264.06 Tg CO2e during 1961 and 2010, respectively. Thus net GTP20 is lower by 6.9% and GTP100 by 2.4% compared to the GTP considering N2O emission alone. The study shows that both warming and cooling effects should be considered to estimate the GTP of N use.

Abstract
Focal recruitment of monocytes and lymphocytes is one of the earliest detectable cellular responses in atherosclerotic lesion formation. Endothelium may regulate leukocyte recruitment by expressing specific adhesion molecules. Interleukin-18 is a proinflammatory cytokine that plays an important role in vascular pathologies. The present study highlights the modulation of adhesion molecules and PPAR-γ by IL-18 and proposes a novel feedback mechanism by which PPAR-γ may regulate IL-18 expression. Three groups of normal chow diet-fed, male Apo E-/- mice, aged 12 weeks (n = 6/group) were employed: Gp I, phosphate-buffered saline (PBS) (2 mo): Gp II, recombinant IL-18 (rIL-18) (1 mo) followed by PBS (1 mo); Gp III, rIL-18 (1 mo) followed by pyrrolidine dithiocarbamate (PDTC) (1 mo). Significantly augmented mRNA expression of ICAM-1 (~5.7-fold), VCAM-1 (~3.6-fold), and NF-κB (~7-fold) was observed in Gp II mice as compared to Gp I, whereas PPAR-γ expression was not altered. PDTC treatment caused a significant downregulation of ICAM-1 (~4.2-fold), VCAM-1(~2-fold), and NF-κB (~4.5-fold) and upregulation of PPAR-γ expression (~5-fold) in Gp III mice. A similar trend was observed in protein expression. In vivo imaging results demonstrated a marked increase in probe (CF750 dye conjugated to VCAM-1 antibody) fluorescence intensity for VCAM-1 expression in Gp II mice, whereas it was moderately decreased in Gp III. PPAR-γ was found to significantly downregulate both IL-18 levels and IL-18-induced adhesion molecules. The underlying mechanism was found to be via inhibition of NF-κB activity by PDTC, thereby leading to decreased adherence of monocytes to the activated endothelial cells and a step to halt the progression and development of atherosclerotic lesions.

Abstract
OBJECTIVE Complex wounds are often difficult to close and sometimes require a split-thickness skin graft (STSG). However, epidermal skin grafts, which contain only an epidermal layer of skin, are a viable option for wound coverage in these challenging wounds. We report our experience using an automated epidermal harvesting tool to harvest epidermal skin grafts for the treatment of complex wounds. METHOD Epidermal skin grafts were harvested from the patient's thigh, which was first washed with isopropyl alcohol. After harvesting, they were transferred to the recipient site using a film dressing. A bolster dressing using gauze and a self-adherent wrap held the grafts in place. RESULTS We selected 34 patients with wounds that had been present from several weeks to over a year. Prior treatments, included skin substitutes, alginate dressings, Unna Boot, and collagen dressings. There were 17 female and 17 male patients with a mean age of 67.1 years (range: 37-103). Wound types were: traumatic wounds, diabetic foot ulcers, venous stasis ulcers, pressure ulcers, and surgical wounds. Patient comorbidities included hypertension, diabetes, congestive heart failure, and osteoarthritis. Mean epithelialisation rate at the recipient site was 7.0 weeks (range: 1-35 weeks). Wound complications included drainage, hypergranulation, and oedema. At follow-up 82.4% (28/34) of wounds were healed, 2.9% (1/34) wounds showed improved healing, 11.8% (4/34) of wounds did not heal, and 2.9% (1/34) were lost to follow-up. All donor sites healed without complications. CONCLUSION In our cohort, use of epidermal skin grafts in conjunction with bolster dressings resulted in full closure or wound improvement of a majority of patients. Epidermal grafting provides another treatment option to physicians when only the epidermal layer is needed. DECLARATION OF INTEREST Dr. Bhatia is a consultant for KCI, an Acelity company.

Abstract
Quantification of greenhouse gases (GHGs) emissions from agriculture is necessary to prepare the national inventories and to develop the mitigation strategies. Field experiments were conducted during 2008-2010 at the experimental farm of the Indian Agricultural Research Institute, New Delhi, India to quantify nitrous oxide (N2O), methane (CH4), and carbon dioxide (CO2) emissions from soils under cereals, pulses, millets, and oilseed crops. Total cumulative N2O emissions were significantly different (P>0.05) among the crop types. Emission of N2O as percentage of applied N was the highest in pulses (0.67%) followed by oilseeds (0.55%), millets (0.43%) and cereals (0.40%). The emission increased with increasing rate of N application (r(2)=0.74, P<0.05). The cumulative flux of CH4 from the rice crop was 28.64±4.40 kg ha(-1), while the mean seasonal integrated flux of CO2 from soils ranged from 3058±236 to 3616±157 kg CO2 ha(-1) under different crops. The global warming potential (GWP) of crops varied between 3053 kg CO2 eq. ha(-1) (pigeon pea) and 3968 kg CO2 eq. ha(-1) (wheat). The carbon equivalent emission (CEE) was least in pigeon pea (833 kg C ha(-1)) and largest in wheat (1042 kg C ha(-1)). The GWP per unit of economic yield was the highest in pulses and the lowest in cereal crops. The uncertainties in emission values varied from 4.6 to 22.0%. These emission values will be useful in updating the GHGs emission inventory of Indian agriculture.

Abstract
Hydronephrosis is a common finding in urinary tract outflow obstruction. Chronically obstructed hydronephrotic system may be associated with parenchymal changes. Ultrasound, intravenous urography, micturating cysto-urethrogram and scintigraphy are commonly performed to evaluate the cause of obstruction. In childhood, pelviureteric junction obstruction is a common cause of the hydronephrosis. Hydronephrosis can also be present in horseshoe kidneys due to poor drainage. However, a large sized hydronephrotic cavity may obscure the finding of horseshoe kidney. A case was reported, and it was diagnosed as horseshoe kidney on follow-up renal dynamic scan and confirmed with the help of dimercaptosuccinic acid SPECT/CT.
