Influenza vaccination and the endurance against air pollution among elderly with acute coronary syndrome

ObjectiveAir pollution, weather condition and influenza are known risk factors of acute coronary syndrome (ACS) among elderly people. The influenza vaccine (IV) has been shown to reduce major cardiovascular events. The purpose of this study was to compare resistance to air pollution and weather factors causing ACS between vaccinated and less-vaccinated elderly people.MethodsA case–crossover design was applied to 1835 elderly ACS patients who were obtained from the 1-million sample of Taiwan National Health Insurance Research Data with inclusion criteria: (1) the first diagnosis of ACS was in cold season and at age 68 or more, (2) had received the free IV program at least once during the period 3 years before the ACS. They were stratified into two groups: 707 had received flu vaccinations for all the 3 years and the remaining 1128 had not. The measurements of air pollutants, temperature, and humidity corresponding to each of the 3 days prior to the ACS diagnosis date were retrieved from the data banks of the Taiwan Environmental Protection Administration and Central Weather Bureau.FindingsIncreases in air pollution concentrations of CO, NO₂, PM₁₀ or PM_2.5 and decreases in temperature significantly influenced the risk of ACS for the non-continuously vaccinated elderly population; however, less significant effects were observed for the continuously vaccinated population.ConclusionConsecutive influenza vaccination may potentially offer resistance against the detrimental effects of air pollution and changes in temperature in frail elderly adults with ACS. Future studies are needed to directly assess the interaction effect between the vaccination and environmental factors on ACS.     

Protocol for the development of consensus-based clinical case reporting guideline extension: CARE for acupuncture

BackgroundHealth research reporting guidelines for case reports (CARE - CAse REport) published in 2013 and 2017 have become a generally accepted standard for publishing case reports. The CARE guidelines represent an architectural framework for writing an evidence-based case report that can be customized as need for a specialty (or disease) if needed. We aim to develop a CARE guideline extension for acupuncture following the EQUATOR Network (Enhancing the QUAlity and Transparency Of health Research) and the 2010″Guidance for Developers of Health Research Reporting". We have established a group of international experts including; clinicians, researchers and methodologists. We performed a needs assessment based on a review of acupuncture case reports published in the indexed medical literature. The needs assessment will be followed by (1) a series of expert interviews to establish a draft, (2) a modified Delphi process, and (3) a consensus meeting. Following the consensus meeting we will pilot test the CARE draft before publishing the CARE extension for acupuncture.MethodsWe will develop the CARE extensions for acupuncture following recommendations of the EQUATOR Network and the 2010 "Guidance for Developers of Health Research Reporting". We will establish an international multidisciplinary group including clinical practitioners, acupuncturists, researchers of reporting guidelines on acupuncture, clinical epidemiologists and statisticians.We performed a needs assessment, reviewing published case reports using acupuncture as a therapeutic intervention from indexed medical journals (PubMed-PMC and Medline, Scopus, Embase, the Allied and Complementary Medicine Database (AMED), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Wan Fang database, Chinese BioMedicine database (CBM), China National Knowledge Infrastructure (CNKI), and VIP). In consultations with advisors we will develop a draft of potential items to be included in the CARE extension for acupuncture. Then we will conduct a modified Delphi process of at least three rounds, hold a face-to-face consensus meeting, pilot test and submit the CARE extension for acupuncture for publication.ConclusionThe development of a widely accepted CARE extension for acupuncture for case reports published in indexed medical journals. These guidelines will follow the EQUATOR Network recommendations and the 2010 "Guidance for Developers of Health Research Reporting".     

Recurrent herpes labialis in the pediatric population: Prevalence,therapeutic studies,and associated complications

Recurrent herpes labialis (RHL) is an incredibly common condition, though the medical literature evaluating pediatric aspects is limited. This paper assesses prevalence and therapeutic studies of pediatric RHL as well as disease complications. A comprehensive literature search of English‐language citations based on PubMed queries of selected terms was performed, with exclusion if methodology was not discussed, or if studies had 10 or fewer patients. RHL prevalence in pediatrics has been assessed by measures of point and periodic prevalence, though methodologic limitations may under‐ or over‐estimate the true prevalence of RHL. Studies have been conducted to evaluate therapeutic safety, tolerability, and efficacy of antivirals in the pediatric population. Pediatric RHL point prevalence ranges from 0.72% to 5.2% depending on the population study and the methodologies used. Pediatric RHL carries a significant public health burden and is often implicated in patients with eczema herpeticum, erythema multiforme, reactive infectious mucositis eruptions, and hypersensitivity reactions. There are few studies that evaluate the rates of occurrence of these sequelae associated with pediatric RHL.
