Clinical Significance of Age at the Time of Diagnosis among Young Breast Cancer Patients

PURPOSE: The aims of this study were to investigate outcomes corresponding to age at diagnosis as categorized into 5-year intervals and to explore whether endocrine-responsive tumors display clinical benefits from endocrine therapy after chemotherapy among young breast cancer patients. METHODS: A total of 1,171 patients who were under 40 years old at diagnosis between 1985 and 2007 were divided into 3 subgroups: ≤30 years (Group I, 13.3%), 31-35 years (Group II, 30.5%), and 36-40 years (Control group, 56.2%). Clinicopathological factors and outcomes were compared using a chi-square test, the Kaplan-Meier method, and Cox's hazards models. RESULTS: There were no significant differences in the characteristics and treatment patterns between the 3 groups, except for the grade, hormone receptors expression, and use of endocrine therap. Group I showed the worst survival and subsequently Group II presented worse outcomes than the Control group, mainly among hormone receptors-positive patients. Groups I and II showed increased risks of recurrence and death in multivariate analyses. Among 529 hormone receptors-positive patients who received chemotherapy, favorable outcomes for patients who were treated with endocrine agents were demonstrated, mainly in patients aged 35 years or less. However, interaction tests between the use of endocrine therapy and age at diagnosis were not significant. CONCLUSION: Age at diagnosis is an independent prognostic factor and the age of 35 years is a rational cut-off among young patients. Our subgroup analysis suggests that endocrine therapy may provide additional benefits even in young breast cancers. Therefore, further researches should be directed towards improving outcomes for this population.ope

The Role of Epidemiology in the Introduction of Vi Polysaccharide Typhoid Fever Vaccines in Asia

Despite the availability of at least two licensed typhoid fever vaccines-injectable sub-unit Vi polysaccharide vaccine and live, oral Ty21a vaccine-for the last decade, these vaccines have not been widely introduced in public-health programmes in countries endemic for typhoid fever. The goal of the multidisciplinary DOMI (Diseases of the Most Impoverished) typhoid fever programme is to generate policy-relevant data to support public decision-making regarding the introduction of Vi polysaccharide typhoid fever immunization programmes in China, Viet Nam, Pakistan, India, Bangladesh, and Indonesia. Through epidemiological studies, the DOMI Programme is generating these data and is offering a model for the accelerated, rational introduction of new vaccines into health programmes in low-income countries. Practical and specific examples of the role of epidemiology are described in this paper. These examples cover: (a) selection of available typhoid fever vaccines to be introduced in the programme, (b) generation of policy-relevant data, (c) providing the 'backbone' for the implementation of other multidisciplinary projects, and (d) generation of unexpected but useful information relevant for the introduction of vaccines. Epidemiological studies contribute to all stages of development of vaccine evaluation and introduction

Switching from originator infliximab to biosimilar versus continuing on originator in inflammatory bowel disease : results from the observational Project NORTH study

Objective Project NORTH compared real-world clinical and economic outcomes in Swedish patients with inflammatory bowel disease (IBD) who switched from originator infliximab to its biosimilar. Materials and methods Data from electronic medical records and Swedish national registries were linked. Switchers (patients switching from originator infliximab to its biosimilar between 1 April 2014, and 31 December 2017) and non-switchers (patients who received originator infliximab and did not switch to a biosimilar by 31 December 2017) were followed up until 31 October 2019. Results Baseline concomitant medication use, disease duration, and inflammatory markers were lower among switchers than non-switchers. At 6 months, the proportion of patients with stable disease was higher among switchers than non-switchers (71/109 [65%] vs 54/107 [50%]; p = .0385); differences were not significant in subsequent follow-ups. At 6 and 24 months, 98% and 93% of switchers, respectively, used concomitant medications versus 96% and 79% of non-switchers. Throughout the study, all-cause treatment discontinuation occurred in 74 (67%) switchers and 105 (95%) non-switchers. At 36-months, mean (SD) number of IBD-related in-patient care days was higher among non-switchers (2.95 [4.71]) than switchers (1.40 [4.20]), as were total medical costs (euro16,740 vs euro3,872). Conclusions No substantial differences in clinical outcomes or healthcare resource utilization were observed between switchers and non-switchers. Several analyses indicate that non-switchers might have more poorly controlled/severe disease than switchers at baseline. Overall, numerous difficulties might arise when executing a high-quality, real-world study, including possible selection bias for patients with better disease control for NMS, limiting the generalizability of the results

Chondroblastoma of the lumbar spine - A case report and review of the literature -

We report a case of chondroblastoma arising in the lumbar spine in a 25-year-old man who presented with low back pain of 5 years duration. Plain radiography and computed tomography revealed a well-defined osteolytic mass surrounded by marginal sclerosis in the third lumbar vertebra. The mass encroached on the left neural foramen on magnetic resonance imaging. Histologically, the tumor consisted of round to oval cells with eosinophilic cytoplasm and randomly scattered osteoclastic type giant cells. There were characteristic chicken-wire calcification and aneurysmal bone cyst-like changes. Chondroblastomas of the lumbar spine are extremely rare, and only nine cases have been reported. Spinal chondroblastoma should be distinguished from other benign bone tumors, because it tends to show aggressive biological behavior with high recurrence and mortality rates

Treatment Patterns, Socioeconomic Status and Clinical Burden in Mild COPD : A Swedish Real-World, Retrospective Cohort Study, the ARCTIC Study

Background: Patients with mild chronic obstructive pulmonary disease (COPD) account for more than half of the total COPD population but are often undiagnosed and sparsely studied. This real-world, longitudinal study compared the socioeconomic burden, clinical characteristics and treatment patterns in patients with mild COPD and age-and gender-matched controls. Patients and methods: Our population included mild COPD patients (forced expiratory volume in one second >= 80% of predicted value) and reference controls from 52 Swedish primary care centres over 15 years (2000-2014). We linked electronic medical record (EMR) data to Sweden's National Health Registries. The outcomes analyzed were socioeconomic status including annual income from work, presence of comorbidities and the use of medications. Results: 844 patients with mild COPD were included in this study and matched with 844 reference controls. Compared with the reference controls, mild COPD patients had a significantly lower annual income from work (mean difference, men: 12,559 euro and women: 7143 euro ) and were significantly less likely to be married or employed. The presence of comorbidities, including cardiovascular disease, anxiety and depression (only women) was significantly higher in mild COPD patients. The use of medications, such as proton pump inhibitors, antidepressants, central painkillers and sleep medications, was significantly higher in the mild COPD group. Conclusion: Mild COPD presents a considerable socioeconomic and clinical burden compared with reference controls The findings suggest that COPD constitutes a condition that influences health status even in mild disease clearly demanding an increased need for early detection and treatment
