Seres modélicos. Entre la naturaleza y el laboratorio

Esta muestra es una adaptación de la exposición virtual www.seresmodelicos.csic.es que el Consejo Superior de Investigaciones Científicas (CSIC) creó en 2011 con la financiación de la Fundación Española para la Ciencia y la Tecnología.Los protagonistas de esta exposición son unos seres pequeños, poco vistosos y a veces incluso molestos. Sin embargo, son organismos modélicos. Pueden pasar desapercibidos en su hábitat natural y, en cambio, generan entusiasmo en los centros de investigación. Se trata de siete especies, como el ratón o la mosca de la fruta, que tienen vidas paralelas entre la naturaleza y el laboratorio. La exposición explica cómo viven en su ambiente natural, cómo y cuándo se introdujeron en el laboratorio y algunas de las investigaciones más relevantes que con su ayuda se están llevando a cabo en la actualidad. ¿Cualquier ser vivo puede ser adecuado para la investigación? ¿Qué aspectos tienen en común las siete especies? ¿Son realmente modélicos? Si os pica la curiosidad, ¡podéis descubrir esto y más visitando la exposición!La exposición itinerante ha sido producida como parte del proyecto de divulgación científica Ciudad Ciencia, una iniciativa del CSIC y de la Obra Social "la Caixa".N

Health and mass unemployment events-developing a framework for preparedness and response

Background Mass unemployment events are not uncommon yet the impact on health is not well recognised. There is a need for a preparedness and response framework, as exists for other events that threaten population health. Methods Framework informed by a narrative review of the impact of mass unemployment on health (studies published in English from 1990 to 2016), and qualitative data from 23 semi-structured interviews with individuals connected to historical national and international events, addressing gaps in published literature on lessons learnt from past responses. Results Economic and employment shock triggered by mass unemployment events have a detrimental impact on workers, families and communities. We present a public health informed response framework which includes (i) identify areas at risk, (ii) develop an early warning system, (iii) mobilise multi-sector action including health and community, (iv) provision of support across employment, finance and health (v) proportionate to need, (vi) extend support to family members and (vii) communities and (viii) evaluate and learn. Conclusion Mass unemployment events have an adverse impact on the health, financial and social circumstances of workers, families, and communities. This is the first framework for action to mitigate and address the detrimental impact of mass unemployment events on population health

Ischemia with no obstructive coronary artery disease (INOCA): A patient self-report quality of life survey from INOCA international.

BACKGROUND: There is limited information available regarding evidence of ischemia with no obstructive coronary arteries (INOCA) and quality of life. PURPOSE: To determine associations between INOCA and self-reported physical, social, and mental health. METHODS: We conducted a survey of all members (n = 1579) of the INOCA International patient support group. Current self-reported diagnosis and health measures were collected. Functional capacity was retrospectively estimated using the Duke Activity Status Index (DASI), assessing levels of activities performed prior and after symptom onset. RESULTS: A total of 297 (20.8% response rate, 91% women) reported symptoms of chest pain, pressure, or discomfort in 92.9%. Overall, 34.4% were living with symptoms for ≥3 years before an INOCA diagnosis, and 77.8% were told their symptoms were not cardiac. Estimated functional capacity was higher prior to compared to after symptom onset (8.6 ± 1.8 METs vs 5.6 ± 1.8 METs; P < 0.0001). Most respondents reported an adverse impact of symptoms on their home life (80.5%), social life (80.1%), mental health (70.4%), outlook on life (69.7%), sex life (55.9%), and their partner/spouse relationship (53.9%), while approximately three-quarters reduced their work hours or stopped work completely, 47.5% retired early, and 38.4% applied for disability. CONCLUSIONS: INOCA symptoms are associated with adverse physical, mental and social health quality of life. Increased patient awareness, physician recognition and diagnosis, and clinical trials are needed to develop evidence-based guidelines for this increasingly recognized cardiovascular disorder

Pesticide-related illness reported to and diagnosed in Primary Care: implications for surveillance of environmental causes of ill-health

BACKGROUND: In Great Britain (GB), data collected on pesticide associated illness focuses on acute episodes such as poisonings caused by misuse or abuse. This study aimed to investigate the extent and nature of pesticide-related illness presented and diagnosed in Primary Care and the feasibility of establishing a routine monitoring system. METHODS: A checklist, completed by General Practitioners (GP) for all patients aged 18+ who attended surgery sessions, identified patients to be interviewed in detail on exposures and events that occurred in the week before their symptoms appeared. RESULTS: The study covered 59320 patients in 43 practices across GB and 1335 detailed interviews. The annual incidence of illness reported to GPs because of concern about pesticide exposure was estimated to be 0.04%, potentially 88400 consultations annually, approximately 1700 per week. The annual incidence of consultations where symptoms were diagnosed by GPs as likely to be related to pesticide exposure was 0.003%, an annual estimate of 6630 consultations i.e. about 128 per week. 41% of interviewees reported using at least one pesticide at home in the week before symptoms occurred. The risk of having symptoms possibly related to pesticide exposure compared to unlikely was associated with home use of pesticides after adjusting for age, gender and occupational pesticide exposure (OR = 1.88, 95% CI 1.51 - 2.35). CONCLUSION: GP practices were diverse and well distributed throughout GB with similar symptom consulting patterns as in the Primary Care within the UK. Methods used in this study would not be feasible for a routine surveillance system for pesticide related illness. Incorporation of environmental health into Primary Care education and practice is needed

Insights to advance our management of myocardial ischemia: From obstructive epicardial disease to functional coronary alterations.

STUDY OBJECTIVE: The Coronary Vasomotor Disorders International Study Group (COVADIS) invited leading experts to address strategies to enhance our clinical understanding of INOCA with an emphasis on the management of coronary vasomotor disorders. DESIGN: Under-recognition of coronary vasomotor disorders, distinguishing different presentations of angina due to vasospasm and/or abnormal microvascular vasodilatation, developing invasive/non-invasive testing and treatment protocols, integrating diagnostic protocols into cardiologists' workflow and trials to inform guideline development were identified as key knowledge gaps and will be briefly addressed in this Viewpoint article. SETTING: Virtual international meeting. PARTICIPANTS: Leading international experts in ischemic heart disease with no obstructive coronary artery disease. INTERVENTIONS: None. MAIN OUTCOME MEASURES: None. RESULTS: Topics discussed include: 1. Obstructive epicardial disease, functional vasospasm and microvascular disorders; 2. Under-recognition of coronary vasomotor disorders in clinical practice; 3. Complexity of coronary vasomotor disorders; 4. Understanding different presentations - vasospastic disease and microvascular angina; 5. Invasive/noninvasive testing and treatment protocols for vasospasm and microvascular angina assessment; 6. Treatment challenges; 7. Integrating diagnostic protocols into cardiologists' workflow; 8. The path forward to advance our approach to managing myocardial ischemia. CONCLUSIONS: Obstructive epicardial disease, functional vasospasm and microvascular disorders often co-exist and contribute to myocardial ischemia. Under-recognition, the complexity of coronary vasomotor disorders, understanding different presentations, testing and treatment protocols, treatment challenges, and integrating diagnostic protocols into cardiologists' workflow all contribute to the path forward to advance our management of myocardial ischemia for improved patient outcomes

Clinical standards in angina and non-obstructive coronary arteries: A clinician and patient consensus statement

Patients with angina and non-obstructive coronary arteries (ANOCA) or myocardial ischaemia with non-obstructive coronary arteries (INOCA) comprise a relatively large subgroup within those with ischaemic heart disease. Advances in the understanding of disease mechanisms, diagnostic tests and multidisciplinary care are improving awareness of the needs of affected individuals. However, practice variations and suboptimal management promulgate the health burden and increase health care resource consumption. Clinical standards represent a limited number of quality statements that describe the care patients should be offered by health professionals and providers for a specific clinical condition or defined clinical pathway in line with current best evidence. Clinical standards should address implementation of this evidence along with education of patients and healthcare professionals, multidisciplinary care networks, and research. In this consensus statement, we highlight contemporary evidence and stakeholder views, including clinicians and patients, to provide an international perspective for developing clinical standards for services involving ANOCA/INOCA patients. A clinical service for ANOCA/INOCA should “consider the whole patient” and provide a multidisciplinary, patient-centred service

Modular prevention of heart disease following acute coronary syndrome (ACS) [ISRCTN42984084]

BACKGROUND: Coronary heart disease (CHD) is a major cause of morbidity and mortality in Australia and it is recommended that all persons with unstable angina (UA) or myocardial infarction (MI) participate in secondary prevention as offered in cardiac rehabilitation (CR) programs. However, the majority of patients do not access standard CR and have higher baseline coronary risk and poorer knowledge of CHD than those persons due to commence CR. The objective of this study is to investigate whether a modular guided self-choice approach to secondary prevention improves coronary risk profile and knowledge in patients who do not access standard CR. METHODS/DESIGN: This randomised controlled trial with one year follow-up will be conducted at a tertiary referral hospital. Participants eligible for but not accessing standard CR will be randomly allocated to either a modular or conventional care group. Modular care will involve participation in individualised modules that involve choice, goal-setting and coaching. Conventional care will involve ongoing heart disease management as directed by the participant's doctors. Both modular and conventional groups will be compared with a contemporary reference group of patients attending CR. Outcomes include measured modifiable risk factors, relative heart disease risk and knowledge of risk factors. DISCUSSION: We present the rationale and design of a randomised controlled trial testing a modular approachfor the secondary prevention of coronary heart disease following acute coronary syndrome

Development and testing of innovative patient resources for the management of coronary heart disease (CHD): a descriptive study

BACKGROUND: Although heart disease is a major cause of morbidity and mortality the majority of patients do not access existing rehabilitation programs and patient resources are not designed to facilitate patient choice and decision-making. The objective of this study was to develop and test a series of risk factor modules and corresponding patient information leaflets for secondary prevention of CHD. METHODS: In phase one, a series of risk factor modules and management options were developed following analysis of literature and interviews with health professionals. In phase two, module information leaflets were developed using published guidelines and interviews of people with CHD. In phase three, the leaflets were tested for quality (DISCERN), readability (Flesch) and suitability (SAM) and were compared to the existing cardiac rehabilitation (CR) information leaflet. Finally, the patients assessed the leaflets for content and relevance. RESULTS: Four key risk factors identified were cholesterol, blood pressure, smoking and physical inactivity. Choice management options were selected for each risk factor and included medical consultation, intensive health professional led program, home program and self direction. Patient information needs were then identified and leaflets were developed. DISCERN quality scores were high for cholesterol (62/80), blood pressure (59/80), smoking (62/80) and physical activity (62/80), all scoring 4/5 for overall rating. The mean Flesch readability score was 75, representing "fairly easy to read", all leaflets scored in the superior category for suitability and were reported to be easy to understand, useful and motivating by persons with CHD risk factors. The developed leaflets scored higher on each assessment than the existing CR leaflets. CONCLUSION: Using a progressive three phase approach, a series of risk factor modules and information leaflets were successfully developed and tested. The leaflets will contribute to shared-decision making and empowerment for persons with CHD

High prevalence of household pesticides and their unsafe use in rural South India

Objective: To estimate the prevalence of usage, unsafe practices and risk perception regarding household pesticides in a rural community of Tamil Nadu, India. Materials and Methods: In a cross-sectional survey we used a pre-tested questionnaire and trained interviewers to collect information on household pesticide use for the past 6 months from any adult member of randomly selected households. Results: Out of 143 households, 95% used at least one household pesticide (95% CI: 93.5-99.5) and 94% used at least one household pesticide specifically for mosquito control. The most commonly used pesticides were mosquito coils (75%), mosquito liquid vaporizers (36%), ant-killing powder (24%) and moth/naphthalene balls (18%). The major non-chemical methods of pest control were rat traps (12%) and mosquito bed nets (7.5%). Out of the mosquito coil users, 61% kept the windows and doors closed while the coil was burning. Out of the moth ball users, 88% left them in the place of use till they fully vaporized. Nearly half of the users did not know that household pesticides were harmful to their health and the health of their children. Conclusions: The use of household pesticides was highly prevalent in this rural community. The prevalence of unsafe practices while handling them was also high. We recommend that the users of household pesticides be educated about the health hazards and about safe practices and non-chemical methods of pest control be promoted
