To the authors' knowledge, this is the first large-scale research assessing outcomes by severity categories for all menstrual symptoms and women's perception of bleeding. A large proportion of women suffer from menstrual symptoms, and symptom severity impacts women's lives. Menstrual symptoms lead to significant economic burden, mainly due to work productivity loss. However, the majority of women do not visit a gynecologist, even when their menstrual symptoms are severe. Thus, increasing public awareness on the recently available medical treatments has the potential to improve the overall burden of menstrual problems.

BackgroundThe importance of incorporating quality-of-life (QoL) assessments into medical practice is growing as health care practice shifts from a “disease-based” to a “patient-centered” model. The prevalence of age-related macular degeneration (AMD) is increasing in today’s aging population. The purpose of this paper is: (1) to discuss, by reviewing the current literature, the impact of AMD on patients’ QoL and the utility of QoL assessments in evaluating the impact of AMD and its treatment; and (2) to make a recommendation for incorporating QoL into clinical practice.MethodsWe conducted a PubMed and an open Internet search to identify publications on the measurement of QoL in AMD, as well as the impact of AMD and the effect of treatment on QoL. A total of 28 articles were selected.ResultsAMD has been found to cause a severity-dependent decrement in QoL that is comparable to systemic diseases such as cancer, ischemic heart disease, and stroke. QoL impairment manifests as greater social dependence, difficulty with daily living, higher rates of clinical depression, increased risk of falls, premature admission to nursing homes, and suicide. The National Eye Institute Visual Functioning Questionnaire (NEI VFQ-25) is the most widely used eye disease-specific QoL instrument in AMD. It has been shown to correlate significantly with visual acuity (VA). QoL reflects aspects of AMD including psychological well-being, functional capacity, and the ability to perform patients’ valued activities, which are not captured by a single, numerical VA score.ConclusionThe literature shows that the adverse impact of AMD on QoL is comparable to serious systemic disease. Eye disease-specific instruments for measuring QoL, such as the NEI VFQ-25, have shown a significant correlation of QoL decrement with measures of disease severity, as well as significant QoL improvement with treatment. The NEI VFQ-25 and other validated instruments provide a wide-ranging assessment of vision-related functioning that is important to patients and complementary to VA measurement. We strongly recommend the incorporation of QoL assessment into routine clinical practice.

The objective of this study was to evaluate the projected health benefits, costs, and cost-effectiveness of pneumococcal conjugate vaccination for infants and children aged <5 years in Canada. A health state model incorporating incidence, vaccine efficacy, costs, and transitional probabilities for the health states (well, meningitis, bacteremia, otitis media, pneumonia, and death) was constructed for a 10-year time horizon. Implementation of a pneumococcal conjugate vaccine program in Canada for each annual birth cohort of 340,000 persons observed over 10 years would be expected to save approximately 12 lives and 100,000 cases of pneumococcal disease over 10 years, resulting in total savings of $67 million (Canadian dollars [Can$]). Vaccination of healthy infants would result in net savings for society if the vaccine costs less than Can$50 per dose. Moreover, for a vaccine purchase price of Can$67.50, infant vaccination would cost society Can$79,000 per life-year gained. Pneumococcal conjugate vaccination is a potentially cost-effective means of pneumococcal disease prevention.

The recommended dose of IgG in primary immunodeficiency (PID) has been increasing since its first use. This study aimed to determine if higher subcutaneous IgG doses resulted in improved patient outcomes by comparing results from two parallel clinical studies with similar design. One patient cohort received subcutaneous IgG doses that were 1.5 times higher than their previous intravenous doses (mean 213 mg/kg/week), whereas the other cohort received doses identical to previous subcutaneous or intravenous doses (mean 120 mg/kg/week). While neither cohort had any serious infections, the cohort maintained on higher mean IgG dose had significantly lower rates of non-serious infections (2.76 vs. 5.18 episodes/year, P < 0.0001), hospitalization (0.20 vs. 3.48 days/year, P < 0.0001), antibiotic use (48.50 vs. 72.75 days/year, P < 0.001), and missed work/school activity (2.10 vs. 8.00 days/year, P < 0.001). The higher-dose cohort had lower health care utilization and improved indices of well being compared to the cohort treated with traditional IgG doses.
