Transforming Healthcare Cybersecurity from Reactive to Proactive: Current Status and Future Recommendations.

The recent rise in cybersecurity breaches in healthcare organizations has put patients' privacy at a higher risk of being exposed. Despite this threat and the additional danger posed by such incidents to patients' safety, as well as operational and financial threats to healthcare organizations, very few studies have systematically examined the cybersecurity threats in healthcare. To lay a firm foundation for healthcare organizations and policymakers in better understanding the complexity of the issue of cybersecurity, this study explores the major type of cybersecurity threats for healthcare organizations and explains the roles of the four major players (cyber attackers, cyber defenders, developers, and end-users) in cybersecurity. Finally, the paper discusses a set of recommendations for the policymakers and healthcare organizations to strengthen cybersecurity in their organization.

Zika Virus infection and microcephaly: anxiety burden for women.

The re-emergence of Zika virus in Brazil and other contiguous countries is a source of anxiety for pregnant women on account of its association with microcephaly. Adverse pregnancy outcome has huge mental health implications. It is essential for health providers to incorporate psychosocial care as part of pre and postnatal care for women in all countries affected by the Zika virus infection.

Too Much or Too Little? How Much Control Should Patients Have Over EHR Data?

Electronic health records (EHRs) have been promoted as a mechanism to overcome the fragmented healthcare system in the United States. The challenge that is being discussed is the rights of the patient to control the access to their EHRs' data and the needs of healthcare professionals to know health data to make the best treatment decisions for their patients. The Federal Trade Commission has asked those who store consumer information to comply with the Fair Information Practice Principles. In the EHR context, these principles give the rights to the patient to control who can see their health data and what components of the data are restricted from view. Control is not limited to patients, as it also includes parents of adolescent children. We suggest that the ongoing policy discussion include consideration of the precise questions patients will be asked when a need for data sharing arises. Further, patients should understand the relative risks that they face, and the degree to which their decisions will (or will not) significantly reduce the risk of a data breach. As various approaches are considered, it is important to address the relative resource requirements and the associated costs of each option.

Mortality outcome among medically underserved women screened through a publicly funded breast cancer control program, 1997-2007.

PURPOSE: The purpose of this study was to assess treatment and mortality differences between women diagnosed with breast cancer through Nebraska's Every Woman Matters (EWM) program and women diagnosed through other sources. METHODS: A retrospective analysis was performed using 10 years of Nebraska Cancer Registry and EWM program data on women aged 40-74 years. This study used chi-square and multivariate logistic regression with mortality as the outcome of interest. RESULTS: From 1997 to 2007, 4,739 women were diagnosed with breast cancer, 435 (9.1 %) of whom were diagnosed through EWM. The EWM and non-EWM groups differed significantly in age, race, marital status, location of residence at the time of diagnosis, neighborhood poverty level at the time of diagnosis, tumor stage at diagnosis, and chemotherapy. No significant differences were found between the two groups in radiation therapy, surgical resection, and hormone therapy. In both 1- and 5-year multivariate mortality models, the odds of dying for those in the EWM program were not statistically significantly different from the odds of dying for those not in the EWM program. In the 1-year mortality model, residents of urban metropolitan counties (OR 2.079; 95 % CI 1.663-2.598) had an increased odds of dying compared to residents of rural counties. In the 5-year mortality model, black women (OR 2.239; 95 % CI 1.453-3.450), residents of areas with a high (more than 20 %) neighborhood poverty level at the time of diagnosis (OR 1.589; 95 % CI 1.204-2.097), and unmarried women (OR 1.334; 95 % CI 1.164-1.528) had higher odds of death. Both groups have received similar treatments. CONCLUSIONS: Targeted outreach to vulnerable groups for cancer screening may improve cancer outcomes and reduce disparities.

Rural-urban differences in acute myocardial infarction mortality: Evidence from Nebraska.

AIMS: Acute myocardial infarction (AMI) remains a major cause of death and disability in the United States and worldwide. Despite the importance of surveillance and secondary prevention, the incidence of and mortality from AMI are not continuously monitored, and little is known about survival outcomes after 30 days of AMI hospitalization or associated risk factors, especially in the rural areas. The current study examines rural-urban differences in both in- and out-hospital survival outcomes for AMI patients. METHODS: We performed a retrospective analysis using hospital discharge data in Nebraska for January 2005 to December 2009 and Nebraska death certificate records through October 2011. Multivariate logistic regression was used to estimate the rural-urban difference in 30-day mortality. A Cox proportional hazard model was used to predict out-of-hospital and overall survival rate. RESULTS: In the 30-day mortality model, after controlling for age, comorbidities, and rehabilitation, patients in urban areas were less likely to die than patients in rural areas (odds ratio: 0.709, 95% confidence interval: 0.626-0.802). In the overall survival model, patients in urban areas had a lower hazard of AMI death (hazard ratio: 0.86, 95% confidence interval: 0.806-0.931) than patients in rural areas. Patients with a previous history of heart failure had a significantly higher likelihood of 30-day mortality, while atrial fibrillation, heart failure, and chronic kidney disease were associated with lower overall survival. Patients who attended at least 1 cardiac rehabilitation session had significantly lower 30-day and overall mortality (p < 0.0001). CONCLUSIONS: This study confirms previous findings on rural-urban disparities in 30-day mortality following AMI hospitalization, and reports new findings on overall rural-urban mortality disparity. The study also found an association between cardiac rehabilitation and reduced mortality, a finding never before reported at the population level. Further efforts are needed to develop systems in rural hospitals and communities to ensure that AMI patients receive recommended care.

Association between endothelial nitric oxide synthase polymorphisms and atrial fibrillation: a meta-analysis.

Several recent studies have focused on the association between the promoter polymorphisms 786T/C of the endothelial nitric oxide synthase (eNOS) gene and susceptibility to atrial fibrillation (AF); however, results have been conflicting. We searched Medline, Embase, and the ISI Web of Science through July 1, 2011. Five studies with 1,130 AF cases and 2,340 controls were selected. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated based on fixed- and random-effects models. There was no overall association between eNOS 786T/C and AF risk. In subgroup analysis, stratified by ethnicity, we observed a positive association between the eNOS 786T/C polymorphism and AF risk among Caucasians but not among mixed populations. When stratifying by control source, the overall ORs for population- and hospital-based studies were 1.07 (95% CI, 0.50-2.30) and 0.79 (95% CI, 0.65-0.97) for CC vs. 22T carriers, respectively. In the studies with a sample size greater than 200, the eNOS 786T/C polymorphism decreased AF risk (OR [95% CI]: 0.79 [0.64-0.97] for CC vs. T carriers). This meta-analysis suggests that the 786T/C polymorphism of the eNOS gene is protective against AF risk among Caucasians. Additional large studies based on diverse populations are required to validate this conclusion.

Tumor necrosis factor-alpha G-308 A polymorphism and risk of coronary heart disease and myocardial infarction: A case-control study and meta-analysis.

OBJECTIVES: The tumor necrosis factor-alpha (TNF-α) gene may play an important role in coronary heart disease (CHD) and myocardial infarction (MI) risk. Recently, controversial results regarding the association of the G-308 A (rs1800629)polymorphism of the TNF-α gene with CHD/MI have been reported. We herein examine a possible association between the G-308 A (rs1800629)polymorphism of the TNF-α gene and CHD/MI in a sample of the Chinese Han population. MATERIALS AND METHODS: We determined the genotypes of TNF-α G-308 A (rs1800629) in 535 unrelated Chinese patients with CHD, 420 patients with MI, and 1020 coronary artery disease-free controls. Additionally, a meta-analysis of all previous studies on the TNF-α G-308 A polymorphism and the risk of CHD and MI was performed. RESULTS: AA genotypes in the G-308 A (rs1800629)polymorphism of the TNF-α gene did not occur more frequently in CHD/MI patients than in controls; odds ratios (95% confidence intervals) were 1.743 (0.325 to 1.423) for CHD and 1.731 (0.442 to 1.526) for MI, after adjusting for conventional risk factors. Further stratification for age, gender, and other cardiovascular risk factors did not alter the prior negative findings. Pooled meta-analysis of 23 studies also found no statistically significant associations between the TNF-α polymorphism and CHD/MI risk in the genetic additive, dominant, and recessive models. Subgroup analyses showed no association between the TNF-α polymorphism and CHD/MI in Asian and Caucasian populations. CONCLUSION: Our study showed no association between the G-308 A (rs1800629) polymorphism of the TNF-α gene (presence of A allele) and CHD/MI in the Chinese Han population. There was no evidence of a difference in risk effects of rs1800629 between Caucasians and Asians.
