Real-world experience of women using extended-cycle vs monthly-cycle combined oral contraception in the United States: the National Health and Wellness Survey
Abstract Background The real-world experience of women receiving extended-cycle combined oral contraception (COC) versus monthly-cycle COC has not been reported. Methods Data were from the United States 2013 National Health and Wellness Survey. Eligible women (18â50 years old, premenopausal, without hysterectomy) currently using extended-cycle COC (3 months between periods) were compared with women using monthly-cycle COC. Treatment satisfaction (1 âextremely dissatisfiedâ to 7 âextremely satisfiedâ), adherence (8-item Morisky Medication Adherence Scale©), menstrual cycle-related symptoms, health-related quality of life (HRQOL) and health state utilities (Medical Outcomes Short Form Survey-36v2Âź), depression (9-item Patient Health Questionnaire), sleep difficulties, Work Productivity and Activity Impairment-General Health, and healthcare resource use were assessed using one-way analyses of variance, chi-square tests, and generalized linear models (adjusted for covariates). Results Participants included 260 (6.7%) women using extended-cycle and 3616 (93.3%) using monthly-cycle COC. Women using extended-cycle COC reported significantly higher treatment satisfaction (Pâ=â0.001) and adherence (Pâ=â0.04) and reduced heavy menstrual bleeding (Pâ=â0.029). A non-significant tendency toward reduced menstrual pain (39.5% versus 47.3%) and menstrual cycle-related symptoms (40.0% versus 48.7%) was found in women using extended-cycle versus monthly-cycle COC. Significantly more women using extended-cycle COC reported health-related diagnoses, indicating preferential prescription for extended-cycle COC among women reporting more health problems. Consistent with this poorer health, more women using extended-cycle COC reported fatigue, headache, and activity impairment (P valuesâ<â0.05). There were no other significant differences between groups. Conclusions This real-world observational study supports extended-cycle COC as a valuable treatment option with high satisfaction, high adherence, and reduced heavy menstrual bleeding
Development and conceptual validation of a questionnaire to help contraceptive choice: CHLOE (Contraception: HeLping for wOmenâs choicE)
Objective: The aim of this research was to develop a questionnaire to facilitate choice of the most appropriate contraceptive method for individual women. Methods: A literature review was conducted to identify key aspects influencing contraceptive choice and inform development of a questionnaire for online completion. Questionnaire development was overseen by a steering committee consisting of eight gynaecologists from across Europe. The initial draft underwent conceptual validation through cognitive debriefing interviews with six native English-speaking women. A qualitative content analysis was conducted to accurately identify potential issues and areas for questionnaire improvement. A revised version of the questionnaire then underwent face-to-face and online evaluation by 115 international gynaecologists/obstetricians with expertise in contraception, prior to development of a final version. Results: The final conceptually validated Contraception: HeLping for wOmenâs choicE (CHLOE) questionnaire takes â€10 min to complete and includes three sections to elicit general information about the individual, the health conditions that might influence contraceptive choice, and the womanâs needs and preferences that might influence contraceptive choice. The questionnaire captures the core aspects of personalisation, efficacy and safety, identified as key attributes influencing contraceptive choice, and consists of 24 closed-ended questions for online completion prior to a health care provider (HCP) consultation. The HCP receives a summary of the responses. Conclusion: The CHLOE questionnaire has been developed to help women choose the contraception that best suits their needs and situation while optimising the HCPâs time.SCOPUS: re.jinfo:eu-repo/semantics/publishe
Multiplicity dependence of light (anti-)nuclei production in pâPb collisions at sNN=5.02 TeV
The measurement of the deuteron and anti-deuteron production in the rapidity range â1 < y < 0 as a function of transverse momentum and event multiplicity in pâPb collisions at âsNN = 5.02 TeV is presented. (Anti-)deuterons are identified via their specific energy loss dE/dx and via their time-of- flight. Their production in pâPb collisions is compared to pp and PbâPb collisions and is discussed within the context of thermal and coalescence models. The ratio of integrated yields of deuterons to protons (d/p) shows a significant increase as a function of the charged-particle multiplicity of the event starting from values similar to those observed in pp collisions at low multiplicities and approaching those observed in PbâPb collisions at high multiplicities. The mean transverse particle momenta are extracted from the deuteron spectra and the values are similar to those obtained for p and particles. Thus, deuteron spectra do not follow mass ordering. This behaviour is in contrast to the trend observed for non-composite particles in pâPb collisions. In addition, the production of the rare 3He and 3He nuclei has been studied. The spectrum corresponding to all non-single diffractive p-Pb collisions is obtained in the rapidity window â1 < y < 0 and the pT-integrated yield dN/dy is extracted. It is found that the yields of protons, deuterons, and 3He, normalised by the spin degeneracy factor, follow an exponential decrease with mass number
Discovery of 42 genome-wide significant loci associated with dyslexia
Auteurs : 23andMe Research Team*, Quantitative Trait Working Group of the GenLang Consortium*International audienceReading and writing are crucial life skills but roughly one in ten children are affected by dyslexia, which can persist into adulthood. Family studies of dyslexia suggest heritability up to 70%, yet few convincing genetic markers have been found. Here we performed a genome-wide association study of 51,800 adults self-reporting a dyslexia diagnosis and 1,087,070 controls and identified 42 independent genome-wide significant loci: 15 in genes linked to cognitive ability/educational attainment, and 27 new and potentially more specific to dyslexia. We validated 23 loci (13 new) in independent cohorts of Chinese and European ancestry. Genetic etiology of dyslexia was similar between sexes, and genetic covariance with many traits was found, including ambidexterity, but n ot n eu ro an at omical measures of language-related circuitry. Dyslexia polygenic scores explained up to 6% of variance in reading traits, and might in future contribute to earlier identification and remediation of dyslexia. The ability to read is crucial for success at school and access to employment, information and health and social services, and is related to attained socioeconomic status 1. Dyslexia is a neurodevelopmental disorder characterized by severe reading difficulties, present in 5-17.5% of the population, depending on diagnostic criteria 2,3. It often involves impaired phonological processing (the decoding of sound units, or phonemes, within words) and frequently co-occurs with psychiatric and other developmental disorders 4 , especially attention-deficit hyperactivity disorde
