Recurrence Rates and Pharmacological Treatment for Hemorrhoidal Disease: A Systematic Review.

INTRODUCTION: Hemorrhoidal disease (HD) is characterized by prolapse of the inflamed and bleeding vascular tissues of the anal canal. Although HD is associated with a high recurrence rate, there is a lack of understanding around interventions that can reduce recurrence and improve outcomes for patients. As such, a systematic literature review (SLR) was conducted to summarize evidence on epidemiology, recurrence, and efficacy of interventions in HD. METHODS: Real-world evidence (RWE) studies evaluating the incidence, prevalence, or recurrence of HD, as well as SLRs including a meta-analytic component reporting on the efficacy of systemic or topical pharmacological treatments for adults with HD, were included. Systematic searches were conducted in MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature, and the Cochrane Database of Systematic Reviews. RESULTS: The SLR identified 44 eligible publications. Consistent data were limited on the epidemiology of HD or HD recurrence. Specifically, incidence and prevalence reported across geographies were impacted by differences in data collection. Reported risk factors for HD were sedentary behavior, constipation, male gender, and age. Twenty-three RWE studies and one meta-analysis reported HD recurrence rates ranging from 0 to 56.5% following surgery or phlebotonics, with most (n = 19) reporting rates of 20% or less. In addition to time since treatment, risk factors for recurring disease were similar to those for HD in general. With respect to treatment, micronized purified flavonoid fractions significantly improved the main symptoms of HD compared to other pharmacological treatments. CONCLUSION: The SLRs did not identify any RWE studies reporting recurrence in patients receiving systemic or topical treatments, highlighting the need for future research in this area. Further, more studies are needed to understand the optimum duration of medical treatment to prevent recurrence.

Patients with hemorrhoidal disease (HD) can experience recurring disease following a period of improvement or remission. It is not well established how often this might happen, who is at greatest risk, or which treatments can reduce this risk. In this study, a systematic literature review (SLR) was conducted to summarize evidence on the occurrence and recurrence of HD, as well as treatment effectiveness. Several literature databases were searched for articles that described real-world evidence (RWE) studies reporting the epidemiology or recurrence of HD as well as published SLRs that combined the results of multiple studies (meta-analyses) on treatment for adults with HD. Forty of 2037 articles identified by the search were considered relevant, and four others identified by clinicians were also included (total = 44; 39 RWE, 5 meta-analyses). Review of the RWE articles revealed that HD epidemiology was determined differently between studies. Only 23 reported recurrence rates (up to 56.5%) after surgery or treatment with phlebotonic drugs (drugs that improve blood flow in veins). Most (19/23) reported recurrence rates of 20% or less. Risk factors for recurrence were similar to usual HD risk factors (e.g., constipation, male gender, age) in addition to time since treatment. Phlebotonic agents, including those made from plant extracts (micronized purified flavonoid fractions, MPFFs) improved hemorrhoidal symptoms compared with placebo or no treatment. In one meta-analysis, MPFF was the only phlebotonic to significantly reduce recurrence risk versus no treatment or placebo. Overall, more research is needed to compare treatments and determine optimal treatment duration to prevent recurrence. Author-narrated video abstract.

Clinical potential of human amniotic fluid stem cells.

OBJECTIVES: To determine whether amniotic fluid derived stem cells maintain their stem cell characteristics (a) after processing by a licensed cell therapy center and (b) after the cells undergo simulated clinical application. METHODS: Amniotic fluid was collected by laparotomy - a small uterine incision was made at proposed site for delivery and a sterile catheter inserted to collect fluid into a sterile bag. After flow stopped the catheter was withdrawn, the cesarean completed and the collected fluid delivered to the cell therapy center for processing and cryostorage. A clinical setting was simulated where amniotic fluid cells received from cell therapy center were thawed at room temperature for a maximum of 3 h and passed through a clinical cell delivery device to monitor cell viability. The cells were examined for viability, stability, growth, differentiation, and markers of stemness. RESULTS: Amniotic fluid stem cells processed from a clinical cell therapy center behave similarly to amniotic fluid stem cells processed in a research laboratory with respects to viability, stability, growth, differentiation and maintain markers of stemness. There were differences due to heterogeneity of samples which were not methodological. Growth in cell culture and differentiation were satisfactory. Simulation of treating the cells in a clinical environment show a general stability in viability of amniotic fluid cells at room temperature for 3 h minimum and when passed through a clinically approved delivery device. CONCLUSIONS: The data indicate human amniotic fluid processed in a clinical facility could be used therapeutically if proven to be safe.

Prevalence and healthcare resource utilization of patients with Dravet syndrome: Retrospective linkage cohort study.

PURPOSE: Prevalence, demography, antiseizure medication (ASM) usage, healthcare resource utilization (HCRU), and mortality of Dravet syndrome (DS) in the UK were investigated using primary and secondary care data in this retrospective cohort study. METHODS: Patients with confirmed DS were anonymously identified from the UK Clinical Practice Research Datalink (CPRD) GOLD database (01/01/1987-31/10/2018) using the DS Read Codes (F25G.11 or F25G.00). Probable DS was identified using the International Classification of Diseases-10/Read Code for epilepsy plus stiripentol or potassium bromide prescription. CPRD data were linked to the Hospital Episode Statistics database and Office for National Statistics to calculate HCRU and mortality. RESULTS: The prevalence of confirmed (n = 32; 1.1/100,000) and probable (n = 22; 0.6/100,000) DS in 2017 was 1.5/100,000. Most patients with DS (confirmed, n = 22/28; probable, n = 8/14) were aged <18 years in 2017. Mean (standard deviation) ASM usage was 5.5 (2.7) in confirmed DS and 7.6 (3.8) in probable DS, over 3.4 (3.5) years and 10.0 (6.2) years of follow-up, respectively. HCRU (per patient-year) was similarly high in patients with confirmed and probable DS; mainly consisting of general practitioner consultations (mean, 4.8-7.9), outpatient visits (5.6-8.3), hospital admissions (0.9-4), and emergency department visits (0.3-2.3). Fewer than five deaths were recorded in patients with confirmed and probable DS. CONCLUSION: Using linked national healthcare databases, our study showed that the UK prevalence of DS recorded in primary care was low, and most cases were in patients aged <18 years. HCRU and ASM usage were similarly high in confirmed or probable DS.

Pharmacological treatment for chronic venous disease: an umbrella review of systematic reviews.

INTRODUCTION: Chronic venous disease is a persistent venous drainage alteration caused by valvular incompetence and/or outflow obstruction. Disease management includes a variety of treatments, whose evidence and clinical performance in the mid-long term are variable. The objective of this umbrella review was to summarize efficacy data for pharmacological treatments including venoactive drugs from previously published reviews that included a meta-analytic component. EVIDENCE ACQUISITION: Systematic database searches were conducted via Ovid SP on 13 August 2019, covering MEDLINE, Embase, and the Cochrane Database of Systematic Reviews. Reviews that included a meta-analytic component of four or more clinical trials or observational studies reporting on the efficacy of systemic or topical pharmacological treatments for adults with chronic venous disease published since 2010 were eligible for inclusion. EVIDENCE SYNTHESIS: Eleven publications were included in this umbrella review. Change in ankle circumference was the most commonly reported outcome. Overall, several systemic treatments had significant effects compared with placebo on multiple efficacy outcomes, including measures of edema and pain. Out of them, Micronized Purified Flavonoid Fraction had the most comprehensive evidence of effectiveness on main symptoms and signs and on improving quality of life throughout chronic venous disease stages. CONCLUSIONS: Systemic pharmacotherapies represent a valuable therapeutic option in CVD management. As a result of this umbrella review, several gaps were identified with respect to research topics that warrant further investigation, particularly in the category of topical medications.

The impact of seizure frequency on quality of life in patients with Lennox-Gastaut syndrome or Dravet syndrome.

OBJECTIVES: Lennox-Gastaut syndrome (LGS) and Dravet syndrome (DS) are rare treatment-resistant epileptic encephalopathies with limited data describing the relationship between seizures and quality of life (QoL). The objective of this cross-sectional pilot study was to assess the impact on QoL of seizures and seizure-free days for the generation of utility values. METHODS: Surveys were conducted in the UK and France, whereby patients and/or caregivers of patients with LGS, DS, or other epilepsies were asked to score health state vignettes for a hypothetical patient with LGS or DS. Respondents evaluated QoL for health states based on the number of seizures and seizure-free days per month, using a visual analog scale (VAS). Visual analog scale scores were converted to the 0-1 scale as a proxy estimate for utility values. Surveys were pilot tested and respondents were recruited from October 2018 to August 2019. RESULTS: Patient respondents were mainly treatment-responsive (n = 43/55) whereas caregiver respondents mainly cared for patients with treatment-resistant epilepsy (n = 38/43). Most respondents and patients were aged ≥18 years. Results from LGS and DS surveys in the UK (n = 58) and France (n = 40) suggested that health states with fewer seizures and more seizure-free days had higher QoL scores for hypothetical patients. For DS, QoL scores for patient health states ranged from 0.20 (32 convulsive seizures and 4 seizure-free days/month, UK) to 0.92 (seizure-free, France). For LGS, scores ranged from 0.14 (130 drop seizures and 1 seizure-free day/month, France) to 0.83 (seizure-free, UK). In all surveys, seizure-free days had a greater impact on QoL than seizure frequency (P < 0.001). CONCLUSIONS: Fewer seizures and additional seizure-free days improved QoL in patients with LGS or DS; seizure-free days had the greatest impact on QoL.

Prevalence, healthcare resource utilization and mortality of Lennox-Gastaut syndrome: retrospective linkage cohort study.

PURPOSE: To retrospectively investigate the prevalence, demography, antiseizure medication (ASM) usage, healthcare resource utilization (HCRU), and mortality of patients with Lennox-Gastaut syndrome (LGS) in primary and secondary care in the UK. METHODS: Patients with confirmed LGS were anonymously identified from the UK Clinical Practice Research Datalink (CPRD) GOLD database (01/01/1987-31/1b0/2018) using the LGS Read Code (F250500). Probable LGS was identified using the International Classification of Diseases-10/Read Code for epilepsy (Hospital Episode Statistics [HES]/CPRD) plus rufinamide prescription. Period prevalence was calculated based on patients enrolled in CPRD GOLD and alive in 2017. CPRD data were linked to HES to calculate HCRU, and to the Office for National Statistics mortality registry. RESULTS: Period prevalence of LGS was 0.578/10,000 (n = 180), with 74 and 106 patients identified with confirmed (0.289/10,000) and probable LGS (0.420/10,000). Mean (max) ASM usage was ~1 (3) per year. In confirmed LGS, valproate (72%), lamotrigine (69%), and clobazam (66%) were the most commonly prescribed ASMs. HCRU (per patient-year) was similar in confirmed and probable LGS and mostly consisted of primary care general practitioner consultations (4-6), outpatient visits (5-10), inpatient admissions (1-4), and A&E visits (1). During the follow-up period, 18 patients died with crude mortality rates of 6.12 (confirmed LGS) and 4.17 (probable LGS) deaths per 1000 person-years. CONCLUSION: Prevalence of LGS appears low in the UK. The similarly high HCRU and mortality rates in confirmed and probable LGS support the validity and specificity of the probable LGS algorithm and high burden of LGS.

Impact of childhood Dravet syndrome on care givers of patients with DS, a major impact on mothers.

BACKGROUND: The aim of this study was to understand the impact of Dravet syndrome (DS) on patients with Dravet syndrome and their families, with a focus on the social and economic impact on both mothers and fathers. METHODS: A French language on-line survey was distributed (October 2014-January 2015) for completion by caregivers of patients aged <18 years with DS. The survey was hosted on the French Dravet Syndrome Alliance website, and the survey link was provided to patients and caregivers during clinics at the Necker Hospital (Paris, France). RESULTS: Survey responses were available for 91 patients (median age 7.6 years; 81.6% SCN1A mutation positive). Total seizure frequency was >2 per week for 16.1% of patients, 1-8 per month for 55.2% and < 1 per month for 28.7%; tonic-clonic and myoclonic were the most frequent seizure types. Patients showed various degrees of intellectual disability and DS had a high impact on concentration and school learning in 70.1% and 80.5%. In addition, patients showed appetite disorders in 73.6%, sleep disorders in 72.4% and behavior disorders in 62.1%. Most parents were married (80.5%) with higher rates than the French general population (53.5%). Educational achievement and socio-professional categories for the parents were higher than observed in the French general population, while monthly net income was similar. Preparation of medication was generally done by the mother and father (46.0% of patients) or the mother only (37.9%). Most caregivers reported very low or no difficulty with treatment preparation and low or no risk of error. Parents typically spent <30 min per day on treatment preparation and administration and around 4 h per week for attending therapy appointments. Although most patients and parents were perceived to have good general health, mothers had a worse perception of their own general health than fathers. Compared with fathers, mothers reported a greater impact of caring for a child with DS on their social life, relationships with family and friends, time and energy, and professional life. CONCLUSION: Families caring for a child with DS experience considerable social and economic impact, with an apparent greater burden of care on the mother than the father.

School-to-work transition for youth with severe physical disabilities: Stakeholder perspectives.

BACKGROUND: Multiple challenges await people with severe physical disability when they are preparing to enter the labour market at the end of the school period. OBJECTIVE: This study aims to better understand the multiple factors that influence the course of disabled youth transitioning into the workforce by gathering perceptions from stakeholders. Methods The study used a qualitative descriptive design with an interpretative description approach to analyze the experiences reported by six school staff, six parents, and three employers. RESULTS: Significant facilitators to the workforce transition were the active involvement of the school's staff in multiplying outreach activities between the various external partners. Significant obstacles include the level of help required to complete day-to-day activities at work and student lack of work experience. Government cutbacks were unanimously identified as the prominent obstacle. CONCLUSIONS: The results presented in this study indicate that a successful school to work transition program is dependent on many factors. These factors include the characteristics of the targeted population, the level of involvement from key stakeholders, the willingness of employers to hire this population, as well as program objectives deviating from paid employment. Further development opportunities have proven to be helpful, such as the development of a solid partnership and collaboration between all stakeholders.

Treatment patterns and real world clinical outcomes in ER+/HER2- post-menopausal metastatic breast cancer patients in the United States.

BACKGROUND: With several new therapies becoming available, treatment of metastatic breast cancer (mBC) is evolving. The objective of this study is to describe patient characteristics, treatment patterns and real-world clinical outcomes in post-menopausal women with ER+, HER2- mBC and to obtain insight into patient outcomes and potential unmet needs with current therapies. METHODS: The current study is a physician survey followed by a retrospective chart review of patient medical records by physicians in the US between March and April 2015. One hundred three physicians were asked to complete an online survey aiming to understand their satisfaction and expectations with current available treatments and potential areas of unmet need for mBC patients. Medical records from 178 females were extracted for the chart review. Using these data from medical records, patient characteristics and treatment patterns were analyzed descriptively. Time to progression (TTP) on first line, and progression-free survival (PFS) on second and third line of therapy were analyzed using the Kaplan-Meier method. RESULTS: Sixty-seven percent (n = 119) of patients had metastatic disease at initial diagnosis of breast cancer. Mean age at chart data extraction was 65.8 (SD: 9.4) years. Aromatase inhibitors (AIs) were prescribed for 58% and around 13% of patients in first line and second line, respectively. Chemotherapy was prescribed to 14% in first line and 31% in second line. Median TTP on first line therapy was 12 months for patients receiving AIs as compared to 7.9 months for patients receiving chemotherapy. Across all treatment lines, bone pain and fatigue were reported as the main symptoms associated with disease progression which had an impact on patient quality of life. Physicians expressed that prolonging life was deemed the most important treatment goal, followed by preservation or improvement of quality of life. CONCLUSION: In this study the majority of patients received endocrine therapy as first line treatment and current therapies still resulted in a short time to progression in first line. Results from the chart review and the physician survey highlight a quantitative unmet need for more effective treatments which delay disease progression and improve survival outcomes while maintaining quality of life.

The Association between Generalized Anxiety Disorder, Subthreshold Anxiety Symptoms and Fear of Falling among Older Adults: Preliminary Results from a Pilot Study.

OBJECTIVE: A relationship between generalized anxiety disorder (GAD) and fear of falling (FOF) has long been proposed but never specifically studied. This study aimed at analyzing the relationship between FOF and GAD or anxiety symptoms, while controlling for major depressive episodes (MDE), depressive symptoms, fall risk, and sociodemographic variables. METHODS: Twenty-five older adults participated in this pilot study. Assessments included the following: Anxiety Disorder Interview Schedule, Geriatric Anxiety Inventory, Geriatric Depression Scale, Falls-Efficacy Scale-International. A multidisciplinary team evaluated fall risk. RESULTS: FOF was significantly correlated with GAD, MDE, anxiety and depressive symptoms, and fall risk, but not with sociodemographic variables. Multiple regression analyses indicated that GAD and anxiety symptoms were significantly and independently associated with FOF. CONCLUSION: Although the results of this pilot study should be replicated with larger samples, they suggest that FOF is associated with GAD and anxiety symptoms even when considering physical factors that increase the risk of falling. CLINICAL IMPLICATIONS: Treatment of FOF in patients with GAD may present a particular challenge because of the central role of intolerance of uncertainty, which may prevent patients from regaining confidence despite the reduction of fall risk. Clinicians should screen for GAD and anxiety symptoms in patients with FOF to improve detection and treatment.

Georgia Primary Care Providers' Knowledge of Hereditary Breast and Ovarian Cancer Syndrome.

Hereditary breast and ovarian cancer syndrome (HBOC) is an inherited condition associated with mutations in the BRCA1 or BRCA2 (BRCA) genes. Identification of individuals with HBOC requires that primary care providers understand the genetic principles required to appropriately collect family history and refer individuals for genetic evaluation. A survey was developed and administered to primary care providers in Georgia to assess their existing knowledge of HBOC and direct targeted educational efforts.We found that Georgia providers demonstrate some knowledge of basic genetic principles but were unable to consistently identify individuals at risk for HBOC. Knowledge deficits included lack of understanding of inheritance patterns and failure to recognize the significance of ovarian cancer history. Strategies for improving identification of patients with HBOC include increasing provider knowledge and integrating HBOC risk assessment tools into practice. Identification of individuals at risk is the critical first step in the process of reducing incidence of breast and ovarian cancer associated with BRCA mutations.

Cost-Effectiveness Analysis of Treating Acute Promyelocytic Leukemia Patients With Arsenic Trioxide and Retinoic Acid in the United States.

INTRODUCTION: This study estimated the cost-effectiveness of arsenic trioxide (ATO) added to all-trans retinoic acid (ATRA) when used in first-line acute promyelocytic leukemia (APL) treatment. MATERIALS AND METHODS: A Markov cohort model was developed with 3 states: stable disease (during first- or second-line treatment), disease event, and death. Newly diagnosed patients with low- to intermediate-risk APL were included and each month could remain in their current health state or move to another. Treatment consisted of ATO + ATRA, ATRA + idarubicin (IDA), or ATRA + cytarabine (AraC) + additional chemotherapy. After an initial disease event, patients discontinued first-line therapy and switched to a second-line ATO regimen. Efficacy and safety data were obtained from published trials; quality of life/utility estimates were obtained from the literature; costs were obtained from US data sources. Costs and outcomes over time were used to calculate incremental cost-effectiveness ratios (ICERs). Deterministic and probabilistic sensitivity analyses were conducted. RESULTS: Compared to ATRA + AraC + additional chemotherapy, ATRA + IDA treatment had ICERs of $2933 per life-year (LY) saved and $3122 per quality-adjusted life-year (QALY) gained. Compared to the ATRA + IDA regimen, first-line ATO + ATRA treatment had ICERs of $4512 per LY saved and $5614 per QALY gained. Results were sensitive to changes in pharmacy costs of the ATO + ATRA regimen during consolidation. CONCLUSION: The ATO + ATRA regimen is highly cost-effective compared to ATRA + AraC + additional chemotherapy or ATRA + IDA in the treatment of newly diagnosed low- to intermediate-risk APL patients.

Budgetary impact of treating acute promyelocytic leukemia patients with first-line arsenic trioxide and retinoic acid from an Italian payer perspective.

The objective of this study was to estimate the net cost of arsenic trioxide (ATO) added to all-trans retinoic acid (ATRA) compared to ATRA plus chemotherapy when used in first-line acute promyelocytic leukemia (APL) treatment for low to intermediate risk patients from the perspective of the overall Italian healthcare systemA Markov model was developed with 3 health states: stable disease, disease event and death. Each month, patients could move from stable to disease event or die from either state. After a disease event, patients discontinued initial treatment and switched to the other regimen as second-line therapy. Treatment regimens, efficacy and adverse events were derived from published sources and expert opinion; unit costs were collected from standard Italian sources. Clinical outcomes and costs for pre-ATO and post-ATO scenarios were combined with population and product utilization information to calculate the total budgetary impact using a 3-year time horizon; one-way sensitivity analyses were conducted. Three-year cumulative pharmacy costs for ATO+ATRA were €46,700 per-patient versus €6,500 for ATRA+chemotherapy; however, medical costs for ATO+ATRA were €12,300 per-patient versus €30,200 for ATRA+chemotherapy. The total budgetary impact was estimated to be an additional €127,300, €312,500 and €477,800 in the first, second and third years, respectively. The model was most sensitive to changes in the cost of the ATO+ATRA regimen during the consolidation phase. Budgetary impact models are valuable to payers making formulary decisions regarding the access and affordability of new medicines. The cost of treatment analysis showed that pharmacy costs for ATO+ATRA were higher than for ATRA+chemotherapy, while all other evaluated costs were lower for ATO+ATRA treated patients. The average budgetary impact was €305,900 per year overall, representing a 3.5% increase. Further research is needed to determine the cost-effectiveness of ATO+ATRA compared to the current first-line standard of care in APL.

End of life or end of the road? Are rising cancer costs sustainable? Is it time to consider alternative incentive and funding schemes?

The number of cancer therapies is increasing. Treatment costs, largely reflecting increasing prices, are also increasing. The regulatory process is increasing in intensity. Countries have initiated risk sharing agreements and/or special cancer funds to accommodate this expenditure growth. Given increasing pressures elsewhere on healthcare budgets, even this response is not sustainable. With many more cancer drugs in the pipeline and the prospects of combination therapy, it is unlikely that the existing policies being applied by payers can maintain budget constraints. Unless payers increase reimbursement and/or extend flexible reimbursement schemes, solutions will be required to ensure access to new cancer therapies - this includes looking at ways of reducing R&D costs. This perspective outlines the problems faced and suggests some solutions.

Cost-Effectiveness of Dolutegravir in HIV-1 Treatment-Naive and Treatment-Experienced Patients in Canada.

INTRODUCTION: The Antiretroviral Analysis by Monte Carlo Individual Simulation (ARAMIS) model was adapted to evaluate the cost-effectiveness of dolutegravir (DTG) in Canada in treatment-naive (TN) and treatment-experienced (TE) human immunodeficiency virus (HIV)-1 patients. METHODS: The ARAMIS-DTG model is a microsimulation model with a lifetime analytic time horizon and a monthly cycle length. Markov health states were defined by HIV health state (with or without opportunistic infection). DTG was compared to efavirenz (EFV), raltegravir (RAL), darunavir/ritonavir, rilpivirine (RPV), elvitegravir/cobicistat, atazanavir/ritonavir and lopinavir/ritonavir in TN patients and to RAL in TE patients. The initial cohort, the main efficacy data and safety data were derived from phase III clinical trials. Treatment algorithms were based on expert opinion. Costs normalized to the year 2013 included antiretroviral treatment cost, testing, adverse event, HIV and cardiovascular disease care and were derived from the literature. RESULTS: Dolutegravir was estimated to be the dominant strategy compared with all comparators in both TN and TE patients. Treatment with DTG was associated with additional quality-adjusted life-years that ranged from 0.17 (vs. RAL) to 0.47 (vs. EFV) in TN patients and was 0.60 in TE patients over a lifetime. Cost savings ranged from Can$1393 (vs. RPV) to Can$28,572 (vs. RAL) in TN patients and amounted to Can$3745 in TE patients. Sensitivity analyses demonstrated the robustness of the model. CONCLUSIONS: Dolutegravir is a dominant strategy in the management of TN and TE patients when compared to recommended comparators. This is mainly related to the high efficacy and high barrier to resistance. FUNDING: ViiV Healthcare.

Impact of public housing relocations: are changes in neighborhood conditions related to STIs among relocaters?

BACKGROUND: Cross-sectional and ecologic studies suggest that place characteristics influence sexual behaviors and sexually transmitted infections (STIs). Using data from a predominately substance-misusing cohort of African American adults relocating from US public housing complexes, this multilevel longitudinal study tested the hypothesis that participants who experienced greater postrelocation improvements in neighborhood conditions (i.e., socioeconomic disadvantage, social disorder, STI prevalence, and male/female sex ratios) would have reduced the odds of testing positive for an STI over time. METHODS: Baseline data were collected in 2009 from 172 public housing residents before relocations occurred; 3 waves of postrelocation data were collected every 9 months thereafter. Polymerase chain reaction methods were used to test participants' urine for Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis. Individual-level characteristics were assessed via survey. Administrative data described the census tracts where participants lived at each wave (e.g., sex ratios, violent crime rates, and poverty rates). Hypotheses were tested using multilevel models. RESULTS: Participants experienced improvements in all tract-level conditions studied and reductions in STIs over time (baseline: 29% tested STI positive; wave 4: 16% tested positive). Analyses identified a borderline statistically significant relationship between moving to tracts with more equitable sex ratios and reduced odds of testing positive for an STI (odds ratio, 0.16; 95% confidence interval, 0.02-1.01). Changes in other neighborhood conditions were not associated with this outcome. DISCUSSION: Consonant with past research, our findings suggest that moving to areas with more equitable sex ratios reduces the risk of STI infection. Future research should study the extent to which this relationship is mediated by changes in sexual network dynamics.

Implementing a screening tool for identifying patients at risk for hereditary breast and ovarian cancer: a statewide initiative.

BACKGROUND: The Georgia Breast Cancer Genomic Health Consortium is a partnership created with funding from the Centers for Disease Control and Prevention (CDC) to the Georgia Department of Public Health to reduce cancer disparities among high-risk minority women. The project addresses young women at increased risk for hereditary breast and ovarian cancer (HBOC) syndrome through outreach efforts. METHODS: The consortium provides education and collects surveillance data using the breast cancer genetics referral screening tool (B-RST) available at www.BreastCancerGeneScreen.org . The HBOC educational protocol was presented to 73 staff in 6 public health centers. Staff used the tool during the collection of medical history. Further family history assessments and testing for mutations in the BRCA1/2 genes were facilitated if appropriate. RESULTS: Data was collected from November 2012 through December 2013, including 2,159 screened women. The majority of patients identified as black/African American and were 18-49 years old. Also, 6.0 % (n = 130) had positive screens, and 60.9 % (n = 67) of the 110 patients who agreed to be contacted provided a detailed family history. A total of 47 patients (42.7 %) met National Comprehensive Cancer Network guidelines when family history was clarified. Fourteen (12.7 %) underwent genetic testing; 1 patient was positive for a BRCA2 mutation, and 1 patient was found to carry a variant of uncertain significance. CONCLUSIONS: The introduction of genomics practice within public health departments has provided access to comprehensive cancer care for uninsured individuals. The successful implementation of the B-RST into public health centers demonstrates the opportunity for integration of HBOC screening into primary care practices.

Cost effectiveness of paliperidone palmitate versus risperidone long-acting injectable and olanzapine pamoate for the treatment of patients with schizophrenia in Sweden.

OBJECTIVE: To model the cost effectiveness of paliperidone palmitate (paliperidone long-acting injectable; PLAI), a new once-monthly long-acting antipsychotic therapy, compared with risperidone long-acting injectable (RLAI) and olanzapine pamoate (OLAI), in multi-episode patients (two or more relapses) with schizophrenia in Sweden. METHODS: A Markov decision analytic model was developed to simulate the history of a cohort of multi-episode patients transitioning through different health states on a monthly basis over a 5-year time horizon from the perspective of the Swedish healthcare system. Therapeutic strategies consisted of starting treatment with RLAI (mean dose 37.5 mg every 2 weeks), PLAI (mean dose 75 mg equivalent (eq.) every month) or OLAI (150 mg every 2 weeks or 300 mg every 4 weeks). Probability of relapse, level of adherence, side-effects (extrapyramidal symptoms, tardive dyskinesia, weight gain and diabetes) and treatment discontinuation (switch) were derived from long-term observational data when feasible. Incremental cost-effectiveness outcomes, discounted at 3% annually, included cost per quality-adjusted life-year (QALY) and cost per relapse avoided (expressed in 2009 Swedish Krona SEK). RESULTS: Relative to RLAI and OLAI, PLAI is economically dominant: more effective (additional QALYs, less relapses) and less costly treatment option over a 5-year time horizon. The results were robust when tested in sensitivity analysis. LIMITATIONS: The impact of once-monthly treatment on adherence levels is not yet known, and not all variables that could impact on real-world outcomes and costs were included in this model. CONCLUSION: PLAI was cost saving from a Swedish payer perspective compared with RLAI and OLAI in the long-term treatment of multi-episode (two or more relapses) schizophrenia patients.

Stated preferences of physicians and chronic pain sufferers in the use of classic strong opioids.

We conducted a two-stage study in France, Germany, Italy, Spain, Sweden, and the United Kingdom of the stated preferences of chronic pain sufferers treated with classic strong opioids and of physicians treating such patients. The qualitative stage identified attributes perceived important through focus groups with 84 pain sufferers and semistructured interviews with 11 physicians. The quantitative stage included online, discrete choice experiments (DCEs) in which respondents chose between hypothetical profiles or an opt-out in 15 choice tasks. The profile descriptions were based on the attributes elicited in the qualitative stage. DCEs were conducted for pain sufferers (N = 242) and physicians (N = 270) who passed a rationality test. Main-effects models were estimated by hierarchical Bayesian regression. Sufferers ranked nausea, pain impact, energy, alertness, and constipation; physicians ranked pain response, central nervous system (CNS) effects, nausea, dose form, and constipation in descending order of importance. Sufferers were unwilling to incur severe side effects to decrease pain and chose the opt-out in approximately one half of the choice tasks, whereas physicians were willing to trade between profiles. The models predicted physicians' choices better than those of pain sufferers. No age, sex, or country effects were seen, but stronger preferences were found among physicians treating noncancer (n = 40) than cancer pain and among the 55% of sufferers who had never discontinued long-term pain medication use. Sufferers' mean pain scores on an 11-point Likert scale were 4.0, 5.7, and 8.6 on their best, average, and worst days, respectively.
