Longitudinal study of the ionospheric response to the geomagnetic storm of 15 May 2005 and manifestation of TADs
Response of low latitude ionosphere to the geomagnetic storm of 15 May 2005
has been studied using total electron content (TEC) data, obtained from
three GPS stations namely, Yibal, Udaipur and Kunming situated near the
northern crest of equatorial ionization anomaly at different longitudes.
Solar wind parameters, north-south component of the interplanetary magnetic
field (IMF <I>B</I><sub>z</sub>) and AE index data have been used to infer the strength of the
geomagnetic storm. A large value of eastward interplanetary electric field
at 06:15 UT, during the time of maximum southward IMF <I>B</I><sub>z</sub> has been used to
infer the transmission of an eastward prompt penetration electric field
(PPEF) which resulted in a peak in TEC at 07:45 UT due to the local uplift of
plasma in the low latitudes near the anomaly crest over a wide range of
longitudes. Wave-like modulations superposed over the second enhancement in
TEC between 09:15 UT to 10:30 UT have been observed at all the three stations.
The second enhancement in TEC along with the modulations of up to 5 TECU
have been attributed to the combined effect of super plasma fountain and
traveling atmospheric disturbances (TAD). Observed large enhancements in TEC
are a cause of concern for satellite based navigation and ground
positioning. Increased [O/N<sub>2</sub>] ratio between 09:15 UT to 10:15 UT when
modulations in TEC have been also observed, confirms the presence of TADs
over a wide range of longitudes
Comparative evaluation of different reference evapotranspiration models
The study was carried out to select best alternative method for the estimation of reference evapotranspi-ration (ET0). Accurate estimation of potential evapotranspiration is a necessary step in water resource management. Recently, the FAO-56 version of Penman-Monteith equation has been established as a standard for calculating ref-erence evapotranspiration (ET0) which requires measurement of a number of meteorological parameters namely, air temperature, relative humidity, solar radiation, and wind speed which may not be available in most of the meteoro-logical stations. Still there are different approaches (requiring less data) which estimate ET0 closely to Penman- Monteith (P-M) method for different climatological conditions. The present study is based on analysis of long term of 13 years (2000 to 2012) climatic data to calculate monthly reference evapotranspiration for Capsicum production (September–March) and also to compare the performance of evapotranspiration equations for Jhalawar district of Rajasthan with the standard FAO-56 Penman-Monteith method on the basis of the least root mean square error (RMSE) analysis. Hargreaves method and Pan evaporation (E-Pan) method overestimated the values of ETo when compared with FAO-56 Penman-Monteith method. On the basis of lowest value of RMSE, Pan evaporation method is found best alternative method to FAO-56 Penman-Monteith method in the study area
Assessment of genetic variability, correlation and path analysis for yield and its components in ajwain (Trachyspermum ammi L.)
Genetic variability, heritability, correlation and path analysis were estimated among 28 germplasm for 10 characters in Ajwain (Trachyspermum ammi L.). Analysis of variance revealed significant differences among the germplasm lines for number of secondary branches plant-1, number of umbels plant-1, number of umbellets umbel-1, seed yield plant-1, harvest index and oil content, suggesting sufficient amount of variability in the experimental material. The estimates of genotypic coefficient variation (GCV) and phenotypic coefficient variation (PCV) indicated the existence of fairly high degree of variability for seed yield plant-1, oil content, number of umbels plant-1 and harvest index. Lower values of GCV and PCV were recorded in number of umbellets umbel-1 indicating the important role of environment in the expression of the characters. High heritability associated with moderate genetic advance was recorded in traits like harvest index and seed yield plant-1. The association study among characters revealed that seed yield was positively and significantly correlated with number of umbellets plant-1. Path coefficient analysis revealed that number of umbellets plant-1 had maximum positive direct effect on seed yield plant-1.
 
Dexamethasone therapy in COVID-19 patients:implications and guidance for the management of blood glucose in people with and without diabetes
The RECOVERY (Randomised Evaluation of COVid-19 thERapY) trial found that dexamethasone 6 mg once per day for 10 days reduced deaths by one-third in ventilated patients and by one-fifth in other patients, receiving oxygen therapy. This equates to the prevention of one death in around eight ventilated patients, or one in around 25 patients requiring oxygen
A guideline for the outpatient management of glycaemic control in people with cancer
Individuals with cancer are at increased risk of developing new onset diabetes mellitus and hyperglycaemia, and an estimated 20% of people with cancer already have an underlying diagnosis of diabetes mellitus.
People with both cancer and diabetes may have an increased risk of toxicities, hospital admissions and morbidity, with hyperglycaemia potentially attenuating the efficacy of chemotherapy often secondary to dose reductions and early cessation. Numerous studies have demonstrated that hyperglycaemia is prognostic of worse overall survival and risk of cancer recurrence.
These guidelines aim to provide the oncology/haemato-oncology and diabetes multidisciplinary teams with the tools to manage people with diabetes commencing anti-cancer/ glucocorticoid therapy, as well as identifying individuals without a known diagnosis of diabetes who are at risk of developing hyperglycaemia and new onset diabetes
ESMO-ESGO consensus conference recommendations on ovarian cancer: Pathology and molecular biology, early and advanced stages, borderline tumours and recurrent disease
The development of guidelines is one of the core activities of the European Society for Medical Oncology (ESMO) and European Society of Gynaecologial Oncology (ESGO), as part of the mission of both societies to improve the quality of care for patients with cancer across Europe. ESMO and ESGO jointly developed clinically-relevant and evidence-based guidelines in several selected areas in order to improve the quality of care for women with ovarian cancer. The ESMO-ESGO consensus conference on ovarian cancer was held on 12-14 April 2018 in Milan, Italy, and comprised a multidisciplinary panel of 40 leading experts in the management of ovarian cancer. Before the conference, the expert panel worked on five clinically relevant questions regarding ovarian cancer relating to each of the following four areas: pathology and molecular biology, early-stage and borderline tumours, advanced stage disease and recurrent disease. Relevant scientific literature, as identified using a systematic search, was reviewed in advance. During the consensus conference, the panel developed recommendations for each specific question and a consensus was reached. The recommendations presented here are thus based on the best available evidence and expert agreement. This article presents the recommendations of this ESMO-ESGO consensus conference, together with a summary of evidence supporting each recommendation
Enhancing diabetes care for the most vulnerable in the 21st century::Interim findings of the National Advisory Panel on Care Home Diabetes (NAPCHD)
Older adults with diabetes may carry a substantial health burden in Western ageing societies, occupy more than one in four beds in care homes, and are a highly vulnerable group who often require complex nursing and medical care. The global pandemic (COVID-19) had its epicentre in care homes and revealed many shortfalls in diabetes care resulting in hospital admissions and considerable mortality and comorbid illness. The purpose of this work was to develop a national Strategic Document of Diabetes Care for Care Homes which would bring about worthwhile, sustainable and effective quality diabetes care improvements, and address the shortfalls in care provided. A large diverse and multidisciplinary group of stakeholders (NAPCHD) defined 11 areas of interest where recommendations were needed and using a subgroup allocation approach were set tasks to produce a set of primary recommendations. Each subgroup was given 5 starter questions to begin their work and a format to provide responses. During the initial phase, 16 key findings were identified. Overall, after a period of 18 months, 49 primary recommendations were made, and 7 major conclusions were drawn from these. A model of community and integrated diabetes care for care home residents with diabetes was proposed, and a series of 5 ‘quick-wins’ were created to begin implementation of some of the recommendations that would not require significant funding. The work of the NAPCHD is ongoing but we hope that this current resource will help leaders to make these required changes happen

Endocrinologic, neurologic, and visual morbidity after treatment for craniopharyngioma
Craniopharyngiomas are locally aggressive tumors which typically are focused in the sellar and suprasellar region near a number of critical neural and vascular structures mediating endocrinologic, behavioral, and visual functions. The present study aims to summarize and compare the published literature regarding morbidity resulting from treatment of craniopharyngioma. We performed a comprehensive search of the published English language literature to identify studies publishing outcome data of patients undergoing surgery for craniopharyngioma. Comparisons of the rates of endocrine, vascular, neurological, and visual complications were performed using Pearson’s chi-squared test, and covariates of interest were fitted into a multivariate logistic regression model. In our data set, 540 patients underwent surgical resection of their tumor. 138 patients received biopsy alone followed by some form of radiotherapy. Mean overall follow-up for all patients in these studies was 54 ± 1.8 months. The overall rate of new endocrinopathy for all patients undergoing surgical resection of their mass was 37% (95% CI = 33–41). Patients receiving GTR had over 2.5 times the rate of developing at least one endocrinopathy compared to patients receiving STR alone or STR + XRT (52 vs. 19 vs. 20%, χ2P < 0.00001). On multivariate analysis, GTR conferred a significant increase in the risk of endocrinopathy compared to STR + XRT (OR = 3.45, 95% CI = 2.05–5.81, P < 0.00001), after controlling for study size and the presence of significant hypothalamic involvement. There was a statistical trend towards worse visual outcomes in patients receiving XRT after STR compared to GTR or STR alone (GTR = 3.5% vs. STR 2.1% vs. STR + XRT 6.4%, P = 0.11). Given the difficulty in obtaining class 1 data regarding the treatment of this tumor, this study can serve as an estimate of expected outcomes for these patients, and guide decision making until these data are available
