Abstract North Atlantic sea surface temperatures experience variability with a periodicity of 60–80 years that is known as the Multidecadal Oscillation (AMO). It has profound imprint on global climate system results in number high value societal impacts. However industrial period, i.e. middle 19th century onwards, contains only two full cycles AMO making it difficult to fully characterize this oscillation and its impact system. As result, there clear need identify paleoclimate records...

Introduction: In mid- to high-latitude regions, cerebrovascular diseases (CBVD) are known peak during the winter. Aside from traditional clinical risk factors, emerging research has documented associations between extreme seasonal climate conditions and CBVD, especially among older male females who vulnerable such environments. Despite growing climate-cerebrovascular literature, there is still a need understand seasonal- sex-specific precipitation CBVD events adults. We hypothesize that will...

Abstract Past research on the relationship between unemployment rates and population health has produced mixed findings. The can be influenced by kinds of outcomes observed, time frame, level geographic aggregation, other factors. Given these findings, there is a need to add our knowledge about how are related. There limited that examines association with both physical mental health, while simultaneously stratifying populations income education levels. Using survey-based self-reported data,...

In recent summers, some populous mid-latitude to high-latitude regions have experienced greater heat intensity, more at night than by day. Such warming has been associated with increased cause-specific adult mortality. Sex-specific and age-specific associations between summer nocturnal surface air temperatures (SAT) cardiovascular disease (CVD) deaths yet be established.A monthly time series analysis (June-July, 2001-2015) was performed on sex-specific CVD in England Wales of adults aged...

Introduction Poor adherence or non-adherence to the prescribed medications among heart failure (HF) patients is a common problem. This leads hospital admission due increased HF exacerbations, reduced physical function, and even death. The study was conducted assess medication level, using Morisky Medication Adherence Scale (MMAS-8), visiting adult cardiology department of tertiary care cardiac center in Karachi. Methods cross-sectional included diagnosed with for follow-up both inpatient...

Abstract Ischemic heart disease (IHD) is one of the leading causes death worldwide. While extreme summer surface air temperatures are thought to be a risk factor for IHD, it unclear whether large-scale climate patterns also influence this risk. This multi-national population-based study investigated association between Pacific and Atlantic sea temperature (SST) variability annual acute myocardial infarction (AMI) or IHD event rates among older adults residing in North America United Kingdom....

Children who receive inadequate exposure to sunlight have reduced levels of vitamin D, resulting in rickets, a disease that is characterized by bone deformity, stunted growth, and long term pronounced disability. The United Kingdom rickets incidence rates declined from the early 1960's mid-1990's, after which there was dramatic increase. reason for this change not well understood. Here we show an important low frequency mode climate variability, Atlantic Multidecadal Oscillation (AMO), with...

Abstract Ischemic heart disease (IHD) is the leading cause of death worldwide. In United States, IHD deaths affect millions adults, with substantial age and race/ethnic-specific variability. recent years, emphasis has been placed on reducing rate events among middle-aged adults. Non-Hispanic (NH) Black populations are known to have greater mortality rates compared other races/ethnicities. Researchers established several biological, clinical, socioeconomic risk factors, but severe climate...
