MorePower 6.0 is a flexible freeware statistical calculator that computes sample size, effect size, and power statistics for factorial ANOVA designs. It also calculates relational confidence intervals for ANOVA effects based on formulas from Jarmasz and Hollands (Canadian Journal of Experimental Psychology 63:124-138, 2009), as well as Bayesian posterior probabilities for the null and alternative hypotheses based on formulas in Masson (Behavior Research Methods 43:679-690, 2011). The program is unique in affording direct comparison of these three approaches to the interpretation of ANOVA tests. Its high numerical precision and ability to work with complex ANOVA designs could facilitate researchers' attention to issues of statistical power, Bayesian analysis, and the use of confidence intervals for data interpretation. MorePower 6.0 is available at https://wiki.usask.ca/pages/viewpageattachments.action?pageId=420413544 .

Volatile hydrocarbon exposures and immune-related illnesses among Deepwater Horizon oil spill workers.
J Expo Sci Environ Epidemiol
December 2024
Department of Epidemiology, UNC Gillings School of Public Health, Chapel Hill, NC, USA.
Background: Despite evidence from experimental studies linking some petroleum hydrocarbons to markers of immune suppression, limited epidemiologic research exists on this topic.
Objective: The aim of this cross-sectional study was to examine associations of oil spill related chemicals (benzene, toluene, ethylbenzene, xylene, and n-hexane (BTEX-H)) and total hydrocarbons (THC) with immune-related illnesses as indicators of potential immune suppression.
Methods: Subjects comprised 8601 Deepwater Horizon (DWH) oil spill clean-up and response workers who participated in a home visit (1-3 years after the DWH spill) in the Gulf Long-term Follow-up (GuLF) Study.
Circulating level of growth-differentiation factor 15 and the functional outcome after acute ischemic stroke: a systematic review and meta-analysis.
Head Face Med
December 2024
The Second Department of Neurology, The First People's Hospital of Nanning, No. 90, Qixing Road, Nanning, Guangxi Province, 530022, China.
Growth-differentiation factor 15 (GDF-15) is a cytokine involved in cellular stress responses and inflammation. This meta-analysis evaluates the association between circulating GDF-15 levels and functional outcomes in patients with acute ischemic stroke (AIS). A comprehensive search of Medline, Web of Science, Embase, Wanfang, and CNKI was conducted up to July 15, 2024.

School of Nursing, Jinan University, Guangzhou, China.
Objectives: Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide, particularly among the elderly, resulting in high rates of intensive care unit (ICU) admissions. Malnutrition is common in elderly patients and has been associated with poor prognosis in patients with COPD. However, its impact in the ICU setting remains incompletely defined.

BMC Geriatr
December 2024
School of Medicine, Henan University of Chinese Medicine, Zhengzhou, Henan, People's Republic of China.
Background: Evidence on the association of dynamic change in frailty index (FI) with risk of all-cause mortality in the older Chinese population is limited. This study aimed to explore the association of 3-year change in FI with risk of all-cause mortality in an older Chinese population.
Methods: We analyzed the data of 4969 participants from the Chinese Longitudinal Healthy Longevity Survey.
The associations between dietary omega-6, omega-3, and omega 6 to omega 3 ratio fatty acids and hypertension risk among adults: a prospective cohort study.

Department of Nutritional Sciences, School of Nutrition Sciences and Food Technology, Kermanshah University of Medical Sciences, Kermanshah, Iran. Electronic address:
Background And Aims: Previous studies have yielded mixed results on the connection between dietary omega-3 and omega-6 intakes and the risk of hypertension (HTN) incidents. Therefore, we conducted a study to survey the connection between baseline dietary intake of omega-3, omega-6, and omega-6 to omega 3 (omega-6/3) fatty acids (FA) and the risk of hypertension.
Methods: We conducted a prospective cohort study and assessed dietary intake through a 118-item food frequency questionnaire (FFQ).
