The agriculture sector is reeling under the pressures of population, land and water scarcity, diseases, disasters and the most challenging of them all, climate change. Although climate change is yet to be charged with affecting agriculture, but in recent years trends of change have been witnessed in various crop production, with a hint of climate's role in it. With the advent of technology, these trends have become easier to analyse and in certain cases predict too. Information Technology (ICT) tools like Geoinformatics are playing a profound role in the agriculture sector and is helping to understand and assess the various factors affecting the growth of crops along with finding out the alternative suitability parameters for better production and distribution. The main aim of this chapter on agro-geoinformatics is to look into this linkage between technology usage and better potato production during adverse conditions.

Abstract Background Few studies have focused on exploring the clinical characteristics and outcomes of COVID-19 in older patients. We conducted this systematic review and meta-analysis to have a better understanding of the clinical characteristics of older COVID-19 patients. Methods A systematic search of PubMed and Scopus was performed from December 2019 to May 3rd, 2020. Observational studies including older adults (age ≥ 60 years) with COVID-19 infection and reporting clinical characteristics or outcome were included. Primary outcome was assessing weighted pooled prevalence (WPP) of severity and outcomes. Secondary outcomes were clinical features including comorbidities and need of respiratory support. Result Forty-six studies with 13,624 older patients were included. Severe infection was seen in 51% (95% CI– 36-65%, I2–95%) patients while 22% (95% CI– 16-28%, I2–88%) were critically ill. Overall, 11% (95% CI– 5-21%, I2–98%) patients died. The common comorbidities were hypertension (48, 95% CI– 36-60% I2–92%), diabetes mellitus (22, 95% CI– 13-32%, I2–86%) and cardiovascular disease (19, 95% CI – 11-28%, I2–85%). Common symptoms were fever (83, 95% CI– 66-97%, I2–91%), cough (60, 95% CI– 50-70%, I2–71%) and dyspnoea (42, 95% CI– 19-67%, I2–94%). Overall, 84% (95% CI– 60-100%, I2–81%) required oxygen support and 21% (95% CI– 0-49%, I2–91%) required mechanical ventilation. Majority of studies had medium to high risk of bias and overall quality of evidence was low for all outcomes. Conclusion Approximately half of older patients with COVID-19 have severe infection, one in five are critically ill and one in ten die. More high-quality evidence is needed to study outcomes in this vulnerable patient population and factors affecting these outcomes.

Vote Counting

Over the last twenty years, the debate on financial performance of socially responsible investment (SRI) has not yielded a clear consensus, arguing mainly that there was no difference in performance between SRI and ‘conventional’ investment, although SRI could underperform or outperform in some cases. Our research, based on a meta-analysis ‘vote-counting’ approach of the empirical literature, allows us to observe that the effects of SRI on financial performance are multiple. Second, we conclude that the financial performance of SRI is radically changing according to the empirical methods employed by researchers.

Abstract Objectives The increasing number of hip arthroplasties (HA), due to the growing elderly population, is associated with the risk of femoral periprosthetic fractures (FPFs). The purpose of this study was to identify potential risk factors for the development of FPFs after HA. Methods A systematic review was conducted in five data bases (Medline, Embase, Cochrane, Cinahl, ICTRP) according to the Preferred Reporting Items for Systematic reviews and Meta-analysis (PRISMA) guidelines up to May 2019, using the key words “risk factor,” “periprosthetic fracture,” and “hip replacement or arthroplasty.” Meta-analysis of the clinical outcomes of HA and subgroup analysis based on the factors that were implicated in FPFs was performed. Results Sixteen studies were included (sample size: 599,551 HA patients, 4253 FPFs, incidence 0.71%). Risk factors statistically associated with increased incidence of FPFs were female gender (+ 40%), previous revision arthroplasty surgery (× 3 times), and the presence of rheumatoid arthritis (× 2.1 times), while osteoarthritis (− 57%), cement application (− 59%), and insertion of Biomet (− 68%) or Thompson’s prosthesis (− 75%) were correlated with low prevalence of FPFs. Obesity, cardiac diseases, advanced age, bad general health (ASA grade ≥ 3), and use of Exeter or Lubinus prosthesis were not linked to the appearance of FPFs. Conclusion This meta-analysis suggested that female gender, rheumatoid arthritis, and revision arthroplasty are major risk factors for the development of FPFs after a HA. In those patients, frequent follow-ups should be planned. Further prospective studies are necessary to clarify all the risk factors contributing to the appearance of FPFs after HA.
