Article Synopsis
  • Recent research highlights an increasing use of statistical process control in healthcare data analysis, particularly in cardiology, necessitating the development of new methodologies due to diverse variables.
  • The study utilized generalized additive models (GAMs) and two statistical methods—deviation (D) and Hotelling (T2)—to create control charts for monitoring strokes in patients, revealing that the T2 chart generally outperforms D in detecting medium-to-large process shifts.
  • The findings suggest that these advanced statistical tools can enhance healthcare performance monitoring by effectively analyzing complex relationships among various health factors.

Article Synopsis
  • Wheat is a super important crop for food, but its production has been going down because of drought and water problems.
  • Researchers tested a plant hormone called abscisic acid (ABA) to see if it could help wheat grow better during tough stages when drought makes it hard for the plants to survive.
  • They found that using ABA made the wheat plants taller and healthier, increasing yields and improving many growth factors, which helped the plants deal with the drought better.

Control charts, used in healthcare operations to monitor process stability and quality, are essential for ensuring patient safety and improving clinical outcomes. This comprehensive research study aims to provide a thorough understanding of the role of control charts in healthcare quality monitoring and future perspectives by utilizing a dual methodology approach involving a systematic review and a pioneering bibliometric analysis. A systematic review of 73 out of 223 articles was conducted, synthesizing existing literature (1995-2023) and revealing insights into key trends, methodological approaches, and emerging themes of control charts in healthcare.

Control charts help epidemiologists and healthcare professionals monitor disease incidence and prevalence in real time, preventing outbreaks and health emergencies. However, there remains a notable gap in the comprehensive exploration and application of these techniques, particularly in the context of monitoring and managing disease outbreaks. This study analyses and categorizes worldwide control chart applications from 2000 to 2023 in outbreak monitoring in over 20 countries, focusing on corona-virus (COVID-19), and chooses optimal control charts for monitoring US COVID-19 death waves from February 2020 to December 2023.

Drought stress (DS) is a significant abiotic stress that limits agricultural productivity worldwide. In semi-arid climates, one potential solution to alleviate the deleterious effects of drought is the use of soil amendments such as nanoparticles. The current research was conducted out to probe the sway of drought at critical growth stages (CGS) of wheat crop (D: Control, D: Drought at tillering stage, and D: Drought at anthesis stage) and the application of Cu-nanoparticles (T: 0 mg L, T: 300 mg L, T: 700 mg L, and T: 950 mg L) in order to improve drought resilience.

The control charts are frequently employed in process monitoring to assess the average and variability of a process, assuming a normal distribution. However, it is worth noting that some process distributions tend to exhibit a positively skewed distribution, such as the lognormal distribution. This article proposed a maximum exponential weighted moving average control chart for joint monitoring of mean and variance under a lognormal process.

Article Synopsis
  • The OLS model works best when error terms (mistakes in predictions) follow a normal pattern, but this can be messed up by outliers (unexpected values).
  • Outliers can make the OLS model less useful, so people use M-estimators (MEs) to get better predictions.
  • The new redescending M-estimator (RME) helps deal with outliers better, and tests show it's more effective than other methods in making accurate predictions.

Drought stress is a worldwide threat to the productivity of crops, especially in arid and semi-arid zones of the world. In the present study, the effect of selenium (Se) seed priming on the yield of quinoa under normal and drought conditions was investigated. A pot trial was executed to enhance the drought tolerance in quinoa by Se seed priming (0, 3, 6, and 9 mg Se L).

  • Okra is a widely consumed vegetable facing challenges from salinization and climate change, necessitating the development of salt-tolerant cultivars for sustainable production.
  • A study evaluated 100 okra genotypes for salt tolerance by assessing their morphological and physio-biochemical responses under controlled and saline conditions.
  • Results revealed significant genetic variability among genotypes, with five genotypes (95, 111, 133, 99, and 128) demonstrating both high yield and salt tolerance, essential for breeding efforts.

The coronavirus disease 2019 (COVID-19) pandemic, which emerged in late 2019, has caused millions of infections and fatalities globally, disrupting various aspects of human society, including socioeconomic, political, and educational systems. One of the key challenges during the COVID-19 pandemic is accurately predicting the clinical development and outcome of the infected patients. In response, scientists and medical professionals globally have mobilized to develop prognostic strategies such as risk scores, biomarkers, and machine learning models to predict the clinical course and outcomes of COVID-19 patients.

  • Drought is hurting wheat production, a major food crop, due to climate change and lack of water.
  • Scientists tested the use of nano-biochar (NBC) and brassinosteroids (BR) to help wheat grow better during dry conditions.
  • They found that using both NBC and BR together led to the best results, making the wheat plants taller and producing more grains compared to just using one or none.

Drought is a major abiotic factor and affects cereal-based staple food production and reliability in developing countries such as Pakistan. To ensure a sustainable and consistent food supply, holistic production plans involving the integration of several drought mitigation approaches are required. Using a randomized complete block design strategy, we examined the drought-ameliorating characteristics of plant growth-promoting rhizobacteria (PGPR) and nanoparticles (NPs) exclusively or as a combined application (T) through three stages (D, D, and D) of wheat growth (T, control).

Drought stress is a major limitation in wheat production around the globe. Organic amendments could be the possible option in semi-arid climatic conditions to mitigate the adverse effects of drought at critical growth stages. Wheat straw biochar (BC0 = Control, BC1 = 3% biochar and BC2 = 5% biochar) was used to alleviate the drought stress at tillering (DTS), flowering (DFS), and grain filling (DGFS) stages.
