Early reperfusion in patients with ST-segment elevation myocardial infarction (STEMI) has been associated with preservation of left ventricular function and decrease in mortality. Symptom onset to first medical contact (FMC) time consumes the majority of total ischemic time, and remains one of the main reasons that patients do not receive timely care. With FMC to reperfusion time being effectively reduced in many parts of the world, the focus is now shifting to reducing symptom onset to FMC times.

This mixed-methods observational study was designed to elucidate factors affecting symptom onset to FMC time at a regional cardiac center in a low-middle income country (LMIC) and a high-income country (HIC). A review of the Aswan Heart Center and Hamilton General Hospital STEMI registry in Egypt and Canada was conducted, and retrospective semi-structured questionnaires carried out for a convenience sample of 158 patients.

Gender, symptom type and severity were none-modifiable factors found between early and late presenters. Modifiable factors found were actions of bystanders, actions of patients, transportation method and time. Emotional factors also showed differences between the two groups.

While some concepts are generalizable, contextual differences in demographics, risk factors, access and knowledge are identified. These factors can be used to inform tailored knowledge translation strategies to help reduce symptom onset to FMC in both LMIC and HIC.

Doppler echocardiography has become the leading non-invasive tool for hemodynamic screening and follow-up in various clinical situations. Our objective was to assess whether left atrium (LA) functional echocardiographic parameters correlate with hemodynamic left ventricle (LV) filling parameters measured during right heart catheterization (RHC) in various disease states.

Echocardiographic examinations of 71 consecutive patients that had RHC within 24h were studied retrospectively using LA/LV feature tracking analysis. Echocardiographic and myocardial mechanics characteristics were then correlated with the RHC findings.

The best correlation were demonstrated between the

-tricuspid gradient in the echocardiogram and the right ventricle (RV) systolic pressure in the RHC (R

=0.41, p<0.0001). Mitral E/E' annular velocity ratio did not correlate with capillary wedge pressure (CWP) while E velocity correlated significantly with CWP (R

=0.29, p=0.0007). Among 38 patients in sinus rhythm, echocardiographic diastolic dysfunction strongly correlated with elevated LA pressure in RHC (CWP≥12mmHg, p=0.001), with 96% sensitivity and 80% specificity. LA minimal volume index (LAVmin-i) as measured by echocardiogram was significantly correlated with elevated LA pressure in RHC (p=0.04, criterion≥27ml) regardless of rhythm.

In patients with sinus rhythm, diastolic dysfunction was found to be sensitive and specific for elevated CWP≥12mmHg at RHC. In all patients regardless of rhythm, LAVmin-i was found to correlate best with elevated LA pressure at RHC. This may suggest a new tool for assessment of diastolic dysfunction in all subjects.

Data from the 2011-2018 National Health and Aging Trends Study for respondents aged 65 years and older (N = 10,548, mean age = 77.5) were analyzed using linear mixed effect models. Racial/ethnic differences (mutually-exclusive groups non-Latino White, non-Latino Black, and Latino) in cognitive trajectories and significant interactions with sex and education ( less then high school, high school, some college, and ≥ college degree) were evaluated. Models included sex, education, ever covered by Medicaid, coupled status, waist-height ratio, study cohort, and chronic disease category (no diseases; one disease; advanced cardiovascular multimorbidity; metabolic multimorbidity; advanced cardiovascular-metabolic multimorbidity; and neither advanced cardiovascular nor metabolic multimorbidity). In covariate-adjusted models, Black (b = -1.31, 95% CI 1.74,-0.89) and Latino (b = -0.83, 95% CI 1.58,-0.07) respondents had lower cognitive scores at age 65 and steeper declines with age (b = -0.08, 95% CI -0.15,-0.01; b = -0.20, 95% CI 0.34,-0.05, respectively) compared with White respondents. Cognitive scores were lower among respondents with advanced cardiovascular (b = -0.28, 95% CI 0.54,-0.01) and advanced cardiovascular-metabolic (b = -0.56, 95% CI 0.86,-0.27) multimorbidity compared with respondents with none of the chronic diseases of interest. In interaction models, protective associations by female sex and higher education were not observed among minority racial/ethnic groups. It is important to develop interventions to postpone cognitive decline among older Black and Latino adults.In spring 2015, the South Korean province of South Gyeongsang stopped providing free school lunches to primary and secondary school students while large portions of schools in other provinces continued to provide free lunches at school. After the provincial government faced strong opposition, South Gyeongsang reintroduced the free-school-lunch program the very next year. Using a difference-in-differences design, we exploit these policy changes to evaluate their impact on students' body mass index (BMI) and on a measure related to students' mental health status (MH). Our results show that the abolishment of free school lunches harmed (female) underweight students by causing additional weight losses of about 4.5 percent whereas the reintroduction of free school lunches led to an average weight loss of 2.1 percent among overweight students (both male and female). Moreover, the school lunch policy changes had significant impacts on our MH measure crying without any reason increased when the free-school-lunch policy was abolished and it decreased when the policy was reintroduced. The results are of great interest to decision makers introducing free school lunches helps to achieve healthier weights and decreases crying without any reason and as a result, benefits student welfare. Free-school-lunch policies, therefore, may provide simple and inexpensive means to improve the health and welfare of students.

Co-design has increasingly been posited as a useful approach for Indigenous peoples and other social groups that experience inequities. However, the relatively rapid rise in co-design rhetoric has not necessarily been accompanied by increased understanding of whether co-design works for these social groups, and how equity is addressed.

We conducted a systematic review to identify the current state of co-design as theory and praxis within the context of health and/or disability related interventions or services, with a specific focus on equity considerations for Indigenous and other children and young people from priority social groups. Six electronic databases were searched systematically to identify peer-reviewed papers and grey literature (dissertation and theses) published between January 1, 2000 to December 31, 2020, and a hand-search of reference lists for selected full texts was undertaken.

Fifteen studies met the inclusion criteria. Although all studies used the term 'co-design', only three provi extent to which the literature can be definitive as to whether co-design works for Indigenous and other children and young people from priority social groups, or whether co-design reduces health inequities. It is critical for quality reporting to occur regarding co-design definitions, theory, and praxis. There is an urgent requirement for evaluation research that focuses on co-design impacts and assesses the contribution of co-design to achieving equity. We also recommend culturally safe ethical processes be implemented whenever undertaking co-design.During the ongoing COVID-19 pandemic, there were several reports of SARS-CoV-2 transmission from human to animals, mostly to companion cats and dogs but also to free ranging wild species like minks and deers. Under this scenario, SARS-CoV-2 surveillance in domestic animals to assess the risk of transmission between species have been suggested by the OIE. Here we present a case report of SARS-CoV-2 infection in free roaming dogs, found at a rural indigenous community from the Ecuadorian Amazonia. Oral and nasal swabs samples were collected from three dogs found during a COVID-19 surveillance intervention in Amazonian indigenous communities where severe COVID-19 outbreaks were suspected. Total RNA was extracted from dog samples and detection of SARS-CoV-2 gene targets N, ORF1ab and S was performed. The three dogs tested positive for at least two SARS-CoV-2 viral targets. Moreover, there was a high SARS-CoV-2 infection rate of 87.2% within this community. Given that 17.1% of SARS-CoV-2 positive individuals had an ultra high load greater than 108 copies/ml, transmission from humans to dogs likely occurred. selleckchem To our knowledge, this study is the first report of SARS-CoV-2 positive free roaming dogs. Also, as those animals were found in the Amazonian forest, SARS-CoV-2 transmission to wild mammals is a potential concern. Given the high presence of free roaming dogs associated to rural and indigenous communities in South America, the potential role of these domestic animals on COVID-19 spread would deserve further surveillance studies involving SARS-CoV-2 detection by PCR and molecular epidemiology based on genome sequencing to confirm human to dog transmission.Nodal metastasis is an independent prognostic factor in patients with melanoma. Sentinel lymph node biopsy (SNB) is a recommended component of the management of patients with AJCC stage T1b or above. The dermal scar is injected with a Technetium-99 m (99MTc) Nanocolloid, a radiotracer that drains into sentinel nodes to be identified on a preoperative SPECT/CT scan. Intraoperatively the sentinel nodes are located using a gamma probe and patent blue dye. A 79-year-old male was referred to the Plastics Outpatient Department for management of a biopsy proven pT4b melanoma on the right flank and a suspicious lesion on the right shoulder. He was scheduled for a SNB and wide local excision of the flank melanoma and excisional biopsy of the shoulder lesion. He received injections of 99MTc Nanocolloid around the flank biopsy scar, however, preoperative, and intraoperative attempts to locate a node using radiological and surgical techniques were unsuccessful. The biopsy of the shoulder lesion sent for histopathology revealed a pT1b melanoma.
