Species-level taxonomy derives from empirical sources (data and techniques) that assess the existence of spatiotemporal evolutionary lineages via various species "concepts." These concepts determine if observed lineages are independent given a particular methodology and ontology, which relates the metaphysical species concept to what "kind" of thing a species is in reality. Often, species concepts fail to link epistemology back to ontology.

Background: The long-COVID syndrome (LCS), defined by residual symptoms from acute COVID-19 for <60 days, affects about one-third of all COVID survivors and is an emerging public health challenge. Empirical data about the range of symptoms or the utility of acupuncture alone for the LCS are very limited.
Case: This observational case study of a 46-year-old male with LCS was conducted to preliminarily define the range of symptoms, a Traditional Chinese Medicine (TCM) diagnostic structure, and evaluate the potential utility of prescribed acupuncture for LCS.
Background Clinical implications of change in the 2017 American College of Cardiology (ACC)/American Heart Association (AHA) guideline on the diagnosis and management of hypertension, compared with recommendations by 2014 expert panel and Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC7), are not known. Methods and Results Using data from the NCDR (National Cardiovascular Data Registry) PINNACLE (Practice Innovation and Clinical Excellence) Registry (January 2013-Decemver 2016), we compared the proportion and clinical characteristics of patients seen in cardiology practices diagnosed with hypertension, recommended antihypertensive treatment, and achieving blood pressure (BP) goals per each guideline document. In addition, we evaluated the proportion of patients at the level of practices meeting BP targets defined by each guideline.

Background: During the COVID-19 crisis, protests against restrictions emerged and rule violations increased, provoking peaks in new positive cases, forcing authorities in France to impose fines to slow down the spread of the disease. Due to these challenges, subsequent implementations of preventive measures in response to COVID-19 recurrences or other pandemics could present difficulties for decision makers. A better understanding of the factors underlying the public acceptance of COVID-19 nonpharmaceutical preventive measures may therefore contribute greatly to the design of more effective public communication during future pandemics.

Although many bleeding lesions are self-limited, the majority of these patients require emergency hospitalization for upper endoscopy (EGD). We conducted a clinical trial to determine if ED risk stratification with video capsule endoscopy (VCE) reduces hospitalization rates for low-risk to moderate-risk patients with suspected upper GI bleeding.

The role of meteorological and air quality factors in moderating the transmission of SARS-CoV-2 and severity of COVID-19 is a critical topic as an opportunity for targeted intervention and relevant public health messaging. Studies conducted in early 2020 suggested that temperature, humidity, ultraviolet radiation, and other meteorological factors have an influence on the transmissibility and viral dynamics of COVID-19. Previous reviews of the literature have found significant heterogeneity in associations but did not examine many factors relating to epidemiological quality of the analyses such as rigor of data collection and statistical analysis, or consideration of potential confounding factors.
