    Human sperm assay (HSA) is a preferred in house quality control and proficiency test (PT) practiced in fertility laboratories. HSA is performed over varying durations, apparently without following set criteria. To better understand the assay time required for reprotoxicity testing in embryo culture media, we compared American-Association-of-Bioanalysts-(AAB-) administered HSA data to our own assay performed using PT samples obtained from AAB. Participating laboratories were required to culture sperm for 48 hours to determine media acceptability. Conclusions drawn from 48- and 24-hour observations were the same, suggesting that HSA could identify reprotoxic media in less time than required by AAB. Our assay revealed that changes in motility grade in adulterated media are significantly different from those in control media. Furthermore, grade changes can be identified earlier than differences in motility loss between samples. Analyzing motility and motility quality together provides a method for establishing an optimal time for HSA

    BACKGROUND: Decisions about how to manage bothersome symptoms of chronic illness are complex and influenced by factors related to the patient, their illness, and their environment. Naturalistic decision-making describes decision-making when conditions are dynamically evolving, and the decision maker may be uncertain because the situation is ambiguous and missing information. Contextual factors, including time stress, the perception of high stakes, and input from others may facilitate or complicate decisions about the self-care of symptoms. There is no valid instrument to measure these contextual factors. The purpose of this study was to develop and test a self-report instrument measuring the contextual factors that influence self-care decisions about symptoms. METHODS: Items were drafted from the literature and refined with patient input. Content validity of the instrument was evaluated using a Delphi survey of expert clinicians and researchers, and cognitive interviews with adults with chronic illness. Psychometric testing included exploratory factor analysis to test dimensionality, item response theory-based approaches for item recalibration, confirmatory factor analysis to generate factor determinacy scores, and evaluation of construct validity. RESULTS: Ten contextual factors influencing decision-making were identified and multiple items per factor were generated. Items were refined based on cognitive interviews with five adults with chronic illness. After a two round Delphi survey of expert clinicians (n = 12) all items had a content validity index of \u3e 0.78. Five additional adults with chronic illness endorsed the relevance, comprehensiveness, and comprehensibility of the inventory during cognitive interviews. Initial psychometric testing (n = 431) revealed a 6-factor multidimensional structure that was further refined for precision, and high multidimensional reliability (0.864). In construct validity testing, there were modest associations with some scales of the Melbourne Decision Making Questionnaire and the Self-Care of Chronic Illness Inventory. CONCLUSION: The Self-Care Decisions Inventory is a 27-item self-report instrument that measures the extent to which contextual factors influence decisions about symptoms of chronic illness. The six scales (external, urgency, uncertainty, cognitive/affective, waiting/cue competition, and concealment) reflect naturalistic decision making, have excellent content validity, and demonstrate high multidimensional reliability. Additional testing of the instrument is needed to evaluate clinical utility

    Self-care management of bothersome symptoms as recommended by clinicians for patients with a chronic condition: A Delphi study

    BACKGROUND: Chronically medically ill patients often need clinical assistance with symptom management, as well as self-care interventions that can help to reduce the impact of bothersome symptoms. Experienced clinicians can help to guide the development of more effective self-care interventions. OBJECTIVE: To create a consensus-based list of common bothersome symptoms of chronic conditions and of self-care management behaviors recommended to patients by clinicians to reduce the impact of these symptoms. METHODS: A two-round Delphi study was performed among an international panel of 47 clinicians using online surveys to identify common and bothersome symptoms and related self-care management behaviors recommended to patients with heart failure, chronic obstructive pulmonary disease, asthma, type 2 diabetes, or arthritis. RESULTS: A total of 30 common bothersome symptoms and 158 self-care management behaviors across the five conditions were listed. Each chronic condition has its own bothersome symptoms and self-care management behaviors. Consensus was reached on the vast majority of recommended behaviors. CONCLUSIONS: The list of common bothersome symptoms and self-care management behaviors reflect consensus across four countries on many points but also disagreement on others, and a few recommendations are inconsistent with current guidelines. Efforts to encourage clinicians to recommend effective self-care management behaviors may reduce symptom impact in chronically ill patient populations

    OBJECTIVE: The aim of this study was to identify for the first time patterns of self-care decision-making (i.e. the extent to which participants viewed contextual factors influencing decisions about symptoms) and associated factors among community-dwelling adults with chronic illness. METHODS: This was a secondary analysis of data collected during the development and psychometric evaluation of the 27-item Self-Care Decisions Inventory that is based on Naturalistic Decision-Making (n = 430, average age = 54.9 ± 16.2 years, 70.2 % female, 87.0 % Caucasian, average number of chronic conditions = 3.6 ± 2.8). Latent class mixture modeling was used to identify patterns among contextual factors that influence self-care decision-making under the domains of external, urgency, uncertainty, cognitive/affective, waiting/cue competition, and concealment. Multivariate multinomial regression was used to identify additional socio-demographic, clinical, and self-care behavior factors that were different across the patterns of self-care decision-making. RESULTS: Three patterns of self-care decision-making were identified in a cohort of 430 adults. A \u27maintainers\u27 pattern (48.1 %) consisted of adults with limited contextual influences on self-care decision-making except for urgency. A \u27highly uncertain\u27 pattern (23.0 %) consisted of adults whose self-care decision-making was largely driven by uncertainty about the cause or meaning of the symptom. A \u27distressed concealers\u27 pattern (28.8 %) consisted of adults whose self-care decision-making was highly influenced by external factors, cognitive/affective factors and concealment. Age, education, financial security and specific symptoms were significantly different across the three patterns in multivariate models. CONCLUSION: Adults living with chronic illness vary in the extent to which contextual factors influence decisions they make about symptoms, and would therefore benefit from different interventions

    Objective: The clinical significance of anti-sperm antibody (ASA) in the etiology of infertility is slowly emerging. Both males and females can make antibodies that react with human sperm. The objective of this study is to investigate the prevalence of serum ASA in male and female patients at various age groups. Materials and methods: A routine ASA screening was done on 680 patients registered for infertility treatment. The prevalence of ASA was estimated as percentage of ASA positive patients in different age and sex groups. The strength of the relationship of positive samples with the age and sex of the patients were tested by statistical analysis. Results: A total of 39 (5.73%) out of 680 patients (336 male and 344 female) were ASA positive. Irrespective of the gender, the 2.5%, 6.82%, and 8.08% patients were positive in the age group of ≤30, 31-40, and ≥41 yr., respectively. The 4.36% female and 7.14% male were positive, the difference between the sexes is not statistically significant (p = 0.12). In female, 1.75%, 5.97%, and 4.35% whereas in male 3.48%, 7.61%, and 11.32% were ASA positive in ≤30, 31-40, and ≥41 yr. age group, respectively. Conclusions: Less than 10% infertile patient of all etiologies is positive by circulating ASA, and ASA prevalence probably increases with patient’s age

    Objective: Determine any disparities in care based on race, ethnicity and language (REaL) by utilizing inpatient (IP) core measures at Texas Health Resources, a large, faith-based, non-profit health care delivery system located in a large, ethnically diverse metropolitan area in Texas. These measures, which were established by the U.S. Centers for Medicare and Medicaid Services (CMS) and The Joint Commission (TJC), help to ensure better accountability for patient outcomes throughout the U.S. health care system. Methods: Sample analysis to understand the architecture of race, ethnicity and language (REaL) variables within the Texas Health clinical database, followed by development of the logic, method and framework for isolating populations and evaluating disparities by race (non-Hispanic White, non-Hispanic Black, Native American/Native Hawaiian/Pacific Islander, Asian and Other); ethnicity (Hispanic and non-Hispanic); and preferred language (English and Spanish). The study is based on use of existing clinical data for four inpatient (IP) core measures: Acute Myocardial Infarction (AMI), Congestive Heart Failure (CHF), Pneumonia (PN) and Surgical Care (SCIP), representing 100% of the sample population. These comprise a high number of cases presenting in our acute care facilities. Findings are based on a sample of clinical data (N = 19,873 cases) for the four inpatient (IP) core measures derived from 13 of Texas Health’s wholly-owned facilities, formulating a set of baseline data. Results: Based on applied method, Texas Health facilities consistently scored high with no discernable race, ethnicity and language (REaL) disparities as evidenced by a low percentage difference to the reference point (non-Hispanic White) on IP core measures, including: AMI (0.3%–1.2%), CHF (0.7%–3.0%), PN (0.5%–3.7%), and SCIP (0–0.7%)
