2019 ACC/AHA Guideline on the Primary Prevention of Cardiovascular Disease: Executive Summary: A Report of the American College of Cardiology/American Heart Association Task Force on Clinical Practice Guidelines

The subcommittee reviewed the prevalence, incidence, risk factors, natural history, morbidity and questionnaires reported in epidemiological studies of dry eye disease (DED). A meta-analysis of published prevalence data estimated the impact of age and sex. Global mapping of prevalence was undertaken. The prevalence of DED ranged from 5 to 50%. The prevalence of signs was higher and more variable than symptoms. There were limited prevalence studies in youth and in populations south of the equator. The meta-analysis confirmed that prevalence increases with age, however signs showed a greater increase per decade than symptoms. Women have a higher prevalence of DED than men, although differences become significant only with age. Risk factors were categorized as modifiable/non-modifiable, and as consistent, probable or inconclusive. Asian ethnicity was a mostly consistent risk factor. The economic burden and impact of DED on vision, quality of life, work productivity, psychological and physical impact of pain, are considerable, particularly costs due to reduced work productivity. Questionnaires used to evaluate DED vary in their utility. Future research should establish the prevalence of disease of varying severity, the incidence in different populations and potential risk factors such as youth and digital device usage. Geospatial mapping might elucidate the impact of climate, environment and socioeconomic factors. Given the limited study of the natural history of treated and untreated DED, this remains an important area for future research.

TFOS DEWS II Epidemiology Report.

The present guidelines are the most recent data on postoperative nausea and vomiting (PONV) and an update on the 2 previous sets of guidelines published in 2003 and 2007. These guidelines were compiled by a multidisciplinary international panel of individuals with interest and expertise in PONV under the auspices of the Society for Ambulatory Anesthesia. The panel members critically and systematically evaluated the current medical literature on PONV to provide an evidence-based reference tool for the management of adults and children who are undergoing surgery and are at increased risk for PONV. These guidelines identify patients at risk for PONV in adults and children; recommend approaches for reducing baseline risks for PONV; identify the most effective antiemetic single therapy and combination therapy regimens for PONV prophylaxis, including nonpharmacologic approaches; recommend strategies for treatment of PONV when it occurs; provide an algorithm for the management of individuals at increased risk for PONV as well as steps to ensure PONV prevention and treatment are implemented in the clinical setting.

Consensus Guidelines for the Management of Postoperative Nausea and Vomiting

The role of the Tear Film and Ocular Surface Society (TFOS) Dry Eye Workshop (DEWS) II Diagnostic Methodology Subcommittee was 1) to identify tests used to diagnose and monitor dry eye disease (DED), 2) to identify those most appropriate to fulfil the definition of DED and its sub-classifications, 3) to propose the most appropriate order and technique to conduct these tests in a clinical setting, and 4) to provide a differential diagnosis for DED and distinguish conditions where DED is a comorbidity. Prior to diagnosis, it is important to exclude conditions that can mimic DED with the aid of triaging questions. Symptom screening with the DEQ-5 or OSDI confirms that a patient might have DED and triggers the conduct of diagnostic tests of (ideally non-invasive) breakup time, osmolarity and ocular surface staining with fluorescein and lissamine green (observing the cornea, conjunctiva and eyelid margin). Meibomian gland dysfunction, lipid thickness/dynamics and tear volume assessment and their severity allow sub-classification of DED (as predominantly evaporative or aqueous deficient) which informs the management of DED. Videos of these diagnostic and sub-classification techniques are available on the TFOS website. It is envisaged that the identification of the key tests to diagnose and monitor DED and its sub-classifications will inform future epidemiological studies and management clinical trials, improving comparability, and enabling identification of the sub-classification of DED in which different management strategies are most efficacious.

The Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure

Objective To evaluate the validity and reliability of the Ocular Surface Disease Index (OSDI) questionnaire. Methods Participants (109 patients with dry eye and 30 normal controls) completed the OSDI, the National Eye Institute Visual Functioning Questionnaire (NEI VFQ-25), the McMonnies Dry Eye Questionnaire, the Short Form-12 (SF-12) Health Status Questionnaire, and an ophthalmic examination including Schirmer tests, tear breakup time, and fluorescein and lissamine green staining. Results Factor analysis identified 3 subscales of the OSDI: vision-related function, ocular symptoms, and environmental triggers. Reliability (measured by Cronbach α) ranged from good to excellent for the overall instrument and each subscale, and test-retest reliability was good to excellent. The OSDI was valid, effectively discriminating between normal, mild to moderate, and severe dry eye disease as defined by both physician's assessment and a composite disease severity score. The OSDI also correlated significantly with the McMonnies questionnaire, the National Eye Institute Visual Functioning Questionnaire, the physical component summary score of the Short Form-12, patient perception of symptoms, and artificial tear usage. Conclusions The OSDI is a valid and reliable instrument for measuring the severity of dry eye disease, and it possesses the necessary psychometric properties to be used as an end point in clinical trials.

Reliability and validity of the Ocular Surface Disease Index.

Nausea and vomiting following chemotherapy administration are common and often overlooked causes of impairment in cancer patients. The goal of this study was to explore the broad range of consequences associated with this specific acute toxicity of chemotherapy. Specific objectives were: (1) create and test scales specifically designed to assess the impact of chemotherapy-induced nausea and vomiting or patients' daily function; (2) examine changes in quality of life of cancer patients 3 days following chemotherapy administration; (3) assess the impact of chemotherapy-induced emesis on quality of life and patients' daily function; (4) identify medical and non-medical cost-related consequences associated with chemotherapy-induced emesis. Patients receiving intermittent bolus chemotherapy regimens on an out-patient basis were eligible for this survey. Four instruments were used: a patient maintained diary, the Functional Living Index—Cancer (FLIC), a newly created Functional Living Index—Emesis (FLIE) and an Item Check list for cost-related consequences. On Day 1, before chemotherapy, patients completed the FLIC and FLIE. Patients recorded episodes on vomiting, severity of nausea, anxiety, sedation, antiemetics self-administered, and adverse effects in diaries for 3 days following chemotherapy. The FLIC and FLIE were completed at the end of Day 3. The Item Check list of cost-related consequences was administered as a telephone survey on Day 5. Approximately 56% of 122 patients reported chemotherapy-induced emesis (CIE). A change in mean FLIC score indicating a decline in quality of life was observed for the CIE group (119 to 101) but not in the group who did not report emesis (124 to 122). Decline in FLIC and FLIE from before to after chemotherapy administration was greater for CIE patients (p=0.001). FLIE scores indicated that CIE patients perceived that vomiting, and to a slightly lesser extent, nausea substantively influenced their ability to complete household tasks, enjoy meals, spend time with family and friends, and maintain daily function and recreation. Effect size calculations supported a significant negative relationship between occurrence of CIE and the direction and magnitude of functional living index change. An exploratory analysis (principal component followed by regression analysis) supported the hypothesis that side-effects produced by chemotherapy and antiemetic therapy significantly contributed to changes in quality of life observed. Of patients who experienced CIE 23% were unable to go to work due to emesis; 22% reported they were unable to prepare meals due to emesis; 12% reported that emesis made them unable to care for themselves; 12% reported that they were unable to take prescribed medications on at least one occasion during the 3-day period due to emesis. Psychometric assessment of the FLIE support the validity and reliability of the instrument. Reasons for and consequences of chemotherapy-induced emesis in outpatient oncology populations merit further investigation.

Quality of life consequences of chemotherapy-induced emesis.

Background: Public attention and recent US Congressional activity has intensified focus on escalating medication prices. However, the actual cost of medication use extends beyond the up-front cost of purchasing medicines. It also encompasses the additional medical costs of morbidity and mortality resulting from nonoptimized medication regimens, including medication nonadherence. Objectives: Applying the most current nationally representative data sources, our goal was to estimate the cost of prescription drug–related morbidity and mortality in the United States. Methods: Total costs of nonoptimized prescription drug use and average pathway costs for a patient who experienced a treatment failure (TF), a new medical problem (NMP), or a TF and NMP were modeled in Microsoft Excel (Microsoft Corporation, Redmond, WA) and TreeAge Pro Healthcare, v2014 (TreeAge Software, Inc, Williamstown, MA), respectively. Results: The estimated annual cost of prescription drug–related morbidity and mortality resulting from no...

Cost of Prescription Drug-Related Morbidity and Mortality.

We examined patients' experiences with nausea and vomiting after they were discharged from outpatient surgical centers. Data were collected on 211 surgical outpatients at 24-48 h after discharge via a telephone interview conducted by outpatient surgery nurses, and at 5 days after discharge via a patient-completed questionnaire. Telephone interviews were conducted with 193 patients. Questionnaires were completed by 154 patients. Over 35% of patients experienced postdischarge nausea and vomiting. Most had not experienced nausea and vomiting in the recovery room. The severity of nausea for these patients averaged 5 on a 10-point scale (10 indicating very severe nausea). During the 5 days after discharge, these patients reported experiencing nausea for an average of 1.7 days and vomiting for 0.7 days. Patients who experienced postdischarge nausea and vomiting were not able to resume their normal daily activities as quickly as those who did not. Patients managed postdischarge nausea and vomiting with little contact or intervention from health professionals and with minimal product purchases. The results indicate that postdischarge nausea and vomiting is common after outpatient surgery, and that it results in substantial distress and impairment for patients who experience it.
