Low acceptance of intimate partner violence by pregnant women in Uganda predicts higher uptake of HIV self-testing among their male partners.

Introduction: Heterosexual couples are at high risk for HIV acquisition in sub-Saharan Africa, and HIV self-testing (HST) is an additional approach to expand access to HIV testing services. However, it is not well known how gender equality is associated with HST.Methods: We used intervention-arm data from a cluster-randomised controlled HST intervention trial (N = 1 618) conducted in Uganda to determine the association between attitudes towards intimate partner violence (IPV), decision-making power and male partner's uptake of HST among heterosexual couples expecting a child in south-central Uganda. The original study question was to assess the impact of providing pregnant women with HST kits to improve male partner's HIV testing rates. For this analysis, the primary exposures were gender equality (measured by male partner's and female partner's attitudes towards IPV and the female partner's household decision-making power), and the primary outcome was the male partner's uptake of HST. Multivariate logistic regression was used for analysis.Results: We found that male partner HST uptake did not vary depending on male partner's attitudes towards IPV or decision-making power; however, male partner HST uptake did depend on the female partner's attitude towards IPV, with 1.76 times more testing (95% CI 1.06-2.92) in couples where the woman had "medium" versus "high" acceptance of IPV, and 1.82 times more testing (95% CI 1.08-3.08) in couples where the woman had "low" versus "high" acceptance of IPV.Conclusions: This study shows the importance of appropriate negative attitudes by women to IPV in increasing male partner's HST uptake to integrate HST into national health care policies.

The Rates of Nonunion and Malunion in Lower Extremity Fractures: Experience in South Carolina over 17 years.

Our purpose was to determine the rates of lower extremity nonunion and malunion over 17 years in South Carolina. Our hypothesis was that malunions and nonunions decreased over time due to improved access to trauma centers and improved orthopaedic surgical training. The South Carolina Department of Budget and Control Hospital Discharge Database was queried between 1998-2014 and yielded a total of 4,994 malunions and 16,454 nonunions. Malunions increased from 1.2% (1998) to 1.8% (2010); nonunions increased from 4.0% (1999) to 5.8% (2011). Older age and gender were predictive of malunion and nonunion. This study identified females as having a higher odds ratio for malunion or nonunion; higher nonunion rates in worker's compensation or government payer status; and older age as incurring greater risks for sustaining fractures or developing a malunion or nonunion. There was increased prevalence of nonunion and malunion despite improved access to trauma centers and trained orthopaedic trauma surgeons.

Relationship Gender Equality and Couples' Uptake of Oral Human Immunodeficiency Virus Self-Testing Kits Delivered by Pregnant Women in Kenya.

BACKGROUND: Higher gender equality is associated with many human immunodeficiency virus (HIV) preventive behaviors, including HIV testing. HIV self-testing is a relatively new testing technology that could assist with HIV prevention. However, there are no studies examining gender equality and HIV self-testing. We examined the associations between gender equality and couples' uptake of HIV self-testing among heterosexual couples expecting a child in central Kenya. METHODS: This analysis used data from a HIV self-testing randomized intervention trial among pregnant women attending antenatal care and their male partners. The primary exposures were gender equality (measured by the male partner's attitudes toward intimate partner violence, and the woman's report on her household decision making power), and the primary outcome was couples' uptake of HIV self-testing. Generalized linear mixed models framework was used to account for site-level clustering. RESULTS: In comparison to male partners reporting high acceptance of intimate partner violence, couples with male partners reporting medium acceptance (odds ratio, 2.36; 95% confidence interval, 0.99-5.63) or low acceptance (odds ratio, 2.50; 95% confidence interval, 1.20-5.21) were significantly more likely to use HIV self-testing. Gender equality measured by decision making power was not associated with couples' uptake of HIV self-testing. CONCLUSIONS: This study is the first of its kind to examine the association between gender equality and couples' HIV self-testing. This holds important implications for HIV self-testing as we strive to achieve the United Nations Programme on HIV/acquired immune deficiency syndrome goal that 90% of individuals living with HIV should know their status.

Myocardial infarction after epilepsy onset: A population-based retrospective cohort study.

INTRODUCTION: Cardiovascular comorbidities of epilepsy such as hypertension, hyperlipidemia, and diabetes are associated with myocardial infarction (MI). Little data on the development of subsequent cardiovascular disease (CVD) in persons with epilepsy (PWE) are available, with inconsistent findings regarding the association between epilepsy and subsequent MI. A higher risk of MI among adults (without prior MI) following epilepsy diagnosis compared with that among controls was hypothesized. METHODS: This retrospective cohort study used statewide hospital and emergency department (ED) encounter data from 2000-2013 for South Carolina residents aged >18 years without prior MI at the onset of epilepsy, or the first encounter for controls. Persons with epilepsy were compared with 1) persons with migraine (PWM), whose neurological condition has characteristics similar to epilepsy; and 2) persons with isolated lower extremity fracture (PWLF). Subsequent MI was defined as a diagnosis of MI after the first clinical encounter for epilepsy, migraine, or lower extremity fracture (LEF); the association was evaluated with Cox proportional hazard modeling methods. RESULTS: In this study, 2.2% of PWE, 0.6% of PWM, and 1.2% of PWLF had a subsequent MI. Persons with epilepsy were significantly more likely to be non-Hispanic Black (NHB), be covered by Medicaid, and reside in a rural or low income area compared with PWM and PWLF. Specific cardiovascular disease risk factors were more prevalent in PWE than in PWM and PWLF. After adjustment, the hazard of subsequent MI in PWE was 48% higher than in PWM (hazard ratio (HR) = 1.48; 95% confidence intervals (CI) = 1.31-1.67) and 24% higher than in PWLF (HR = 1.24; 95% CI = 1.10-1.39). The hazard of MI increased with increasing age and number of additional comorbidities and was higher in males, those living in rural areas, and those with specific cardiovascular risk factors. CONCLUSION: Persons with epilepsy had moderately elevated risk of subsequent MI compared with PWM or PWLF. The association between epilepsy and MI needs to be further investigated, and clinical care of PWE should include evaluation and management of risk factors for MI.

Determining the joint effect of obesity and diabetes on functional disability at 3-months and on all-cause mortality at 1-year following an ischemic stroke.

BACKGROUND: Obesity and diabetes mellitus, or diabetes, are independently associated with post-ischemic stroke outcomes (e.g., functional disability and all-cause mortality). Although obesity and diabetes are also associated with post-ischemic stroke outcomes, the joint effect of obesity and diabetes on these post-ischemic stroke outcomes has not been explored previously. The purpose of the current study was to explore whether the effect of obesity on post-ischemic stroke outcomes differed by diabetes status in a cohort of acute ischemic stroke subjects with at least a moderate stroke severity. METHODS: Data from the Interventional Management of Stroke (IMS) III clinical trial was analyzed for this post-hoc analysis. A total of 656 subjects were enrolled in IMS III and were followed for one year. The joint effects of obesity and diabetes on functional disability at 3-months and all-cause mortality at 1-year were examined. RESULTS: Of 645 subjects with complete obesity and diabetes information, few were obese (25.74%) or had diabetes (22.64%). Obese subjects with diabetes and non-obese subjects without diabetes had similar odds of functional disability at 3-months following an ischemic stroke (adjusted common odds ratio, 1.038, 95% CI: 0.631, 1.706). For all-cause mortality at 1-year following an ischemic stroke, obese subjects with diabetes had a similar hazard compared with non-obese subjects without diabetes (adjusted hazard ratio, 1.005, 95% CI: 0.559, 1.808). There was insufficient evidence to declare a joint effect between obesity and diabetes on either the multiplicative scale or the additive scale for both outcomes. CONCLUSIONS: In this post-hoc analysis of data from the IMS III clinical trial of acute ischemic stroke patients with at least a moderate stroke severity, there was not sufficient evidence to determine that the effect of obesity differed by diabetes status on post-ischemic stroke outcomes. Additionally, there was not sufficient evidence to determine that either factor was independently associated with all-cause mortality. Future studies could differentiate between metabolically healthy and metabolically unhealthy patients within BMI categories to determine if the effect of obesity on post-stroke outcomes differs by diabetes status.

Risk Factors for Admission and Prolonged Length of Stay in Pediatric Isolated Skull Fractures.

OBJECTIVES: This study aimed to assess management of pediatric isolated skull fracture (ISF) patients by determining frequency of admission and describing characteristics associated with patients admitted for observation compared with patients discharged directly from the emergency department (ED) and those requiring a prolonged hospitalization. METHODS: We evaluated children younger than 5 years who presented with ISF using the South Carolina Traumatic Brain Injury Surveillance and Registry System data from 2001 to 2011. Outcomes analyzed included discharged from ED, admitted for less than 24 hours, and admitted for more than 24 hours (prolonged hospitalization). Bivariate analyses and a polytomous logistic regression model identified factors associated with patient disposition. RESULTS: Five hundred twenty-seven patients met the study criteria (ED discharge = 283 [53%]; inpatient <24 hours = 156 [29%]; inpatient >24 hours = 88 [18%]). The mean length of stay for admissions was 1.9 (SD, 1.5) days. In the regression model, ED discharges had greater odds of presenting to levels 2 to 3 hospitals (level 2: odds ratio [OR], 6.16; 95% confidence interval [CI], 3.66-10.39; level 3: OR, 30.98; 95% CI, 10.92-87.91) and lower odds of a high poverty status (OR, 0.20; 95% CI, 0.10-0.40). Prolonged hospitalizations had greater odds of concomitant injuries (OR, 2.21; 95% CI, 1.12-4.36). CONCLUSIONS: Admission after ISF is high despite a low risk of deterioration. High-poverty patients presenting to high-acuity medical centers are more commonly admitted for observation. Only presence of concomitant injuries was clinically predictive of prolonged hospitalization. The ability to better stratify risk after pediatric ISF would help providers make more informed decisions regarding ED disposition.

Behavioral health in young adults with epilepsy: Implications for transition of care.

AIM: Neurodevelopmental and behavioral health disorders commonly occur with epilepsy, yet risk for young adults is unknown. The aim of this study was to determine the distribution and risk characteristics of neurodevelopmental and behavior health comorbidities among young adults with epilepsy compared with those among young adults with migraine and healthy controls. METHOD: A case-control study examining hospital admission, outpatient, and emergency department (ED) visits for young adults with an ICD-9-CM diagnosis of epilepsy, migraine, or lower extremity fracture (LEF) was conducted. The association of epilepsy, migraine, or LEF with comorbidities was evaluated with univariate and multivariate polytomous logistic regression. RESULTS: From 2000 to 2013, 29,139 young adults ages 19 to 25years were seen in hospitals and EDs for epilepsy (5666), migraine (17,507), or LEF (5966). Young adults with epilepsy had higher proportions of behavioral health comorbidities (51.8%) compared with controls with migraine (37.6%) or LEF (21.6%). In young adults with epilepsy compared with migraine, the increased risk of having any behavioral health comorbidity was 76%, and neurodevelopmental comorbidity was 297%. After adjustment, young adults with epilepsy showed significantly higher odds of each behavioral health comorbidity compared with controls with migraine and LEF. INTERPRETATION: Young adults with epilepsy are particularly susceptible to behavioral health and neurodevelopmental disorders. Results are discussed within the context of transition to adult care.

Population-based comparative analysis of risk of death in children and adolescents with epilepsy and migraine.

OBJECTIVE: Follow-up studies of children and adolescents with epilepsy (CAW-E) have revealed higher risk of mortality than children in the general population. The mortality experience of CAW-E relative to patients with other common neurologic disorders in the pediatric age group is yet undetermined. The objectives of this study are the following: (1) to compare the causes and the adjusted risk of death in CAW-E with that of children and adolescents with migraine (CAW-M) in reference to children and adolescents with lower extremity fracture (CAW-LEF), and children and adolescents in the general population; (2) to evaluate if disparate mortality risks exist by demographic characteristics. METHODS: This retrospective cohort study included 56,781 children and adolescents 0-18 years of age hospitalized or treated in an emergency or outpatient department from 2000 to 2011 for epilepsy, migraine, or lower extremity fracture from all nonfederal health care facilities. Data on deaths were acquired from linked multiple causes of death data file using person-specific unique identifiers. Time of follow-up was from initial clinical encounter to time of death or censoring date of December 31, 2011. The association of risk characteristics with mortality was examined with Cox proportional hazard model after adjusting for potential confounders. RESULTS: Four hundred forty-seven CAW-E and 125 CAW-M died yielding mortality rates of 8.71 and 1.36 per 1,000 person-years, respectively. The 5-year risk of death was 4.38% for CAW-E, 0.68% for CAW-M, and 0.71% for CAW-LEF. Adjusted hazard ratios (HRs) were 3.81 (95% confidence interval [CI] 3.08-3.72) in CAW-E and 1.14 (95% CI 0.94-1.34) in CAW-M relative to CAW-LEF. Risk of death from neurodevelopmental comorbidities was 5.86 (95% CI 4.24-8.08) times greater than those without in the model that compared epilepsy with LEF. SIGNIFICANCE: There is an elevated risk of death in CAW-E with neurodevelopmental comorbidities that remains to be proven.

Stroke after adult-onset epilepsy: a population-based retrospective cohort study.

BACKGROUND: Earlier studies indicate a higher risk of subsequent stroke in PWE aged ≥60. However, little is known of the incidence of subsequent stroke in people with epilepsy (PWE) aged 35 through 60. We determined the risk factors that increase the incidence of stroke following adult-onset epilepsy in a large statewide population over a 10-year period. METHODS: South Carolina hospital discharge and emergency department (ED) data from 2000 to 2011 were used. The study was limited to persons aged ≥35years without prior stroke. Cases included patients diagnosed with epilepsy who were hospitalized or visited the ED. Controls were people with an isolated fracture of the lower extremity without any history of epilepsy or seizure disorders, presumed to approximate the health status of the general population. Epilepsy, fracture, stroke, and comorbid conditions were ascertained by diagnostic codes from health-care encounters. Only persons having stroke occurring ≥6months after the onset of epilepsy or after the first clinical encounter for controls were included. Cox proportional hazards modeling was performed to determine the risk of stroke. RESULTS: There were 21,035 cases with epilepsy and 16,638 controls who met the inclusion criteria. Stroke incidence was 2.5 times higher following adult-onset epilepsy (6.3%) compared with controls (2.5%). After adjusting for comorbidities and other factors, cases with epilepsy showed a 60% higher risk of stroke (HR=1.6; 95% CI: 1.42-1.80) compared with controls. Nearly half of the strokes in cases with epilepsy occurred in those with first diagnosis between ages 35 and 55. Somatic comorbidities associated with increased risk of stroke were more prevalent in cases with epilepsy than controls yet similar in both groups with stroke. Risk of stroke increased with increasing age in both groups. However, the risk of stroke in cases with epilepsy increased faster and was similar to that in controls who were ≥10years older. CONCLUSION: Adult-onset epilepsy at age 35 and older warrants consideration for occult cerebrovascular disease as an etiology of the epilepsy, which may also increase the risk of subsequent stroke. Somatic comorbidities frequently associated with epilepsy include comorbid conditions that share the same underlying pathology with stroke (i.e., hypertension, hyperlipidemia, myocardial infarction, diabetes, and arteriosclerosis). This increased risk of stroke in patients with adult-onset epilepsy should dictate the evaluation and management of stroke risk factors to prevent stroke.

Determining patient needs: A partnership with South Carolina Advocates for Epilepsy (SAFE).

PURPOSE: The purpose of this study was to collaborate with a community partner to administer a current needs assessment of persons with epilepsy (PWE) and determine the types of resources that PWE would like to access through the community partner. METHODS: A self-report needs assessment survey was administered to caregivers and PWE across the state of South Carolina during a community partner educational workshop (n=20) and via secure software distributed through an email link (n=54). KEY FINDINGS: The most frequently reported challenges (>50%) were concerns about finding time to participate in epilepsy community activities, the personal safety of the PWE, finding social connections or social support, finding mental or behavioral health services, and work concerns. However, top ranked concerns centered on personal safety (27.8%), lack of insurance/not enough money to pay for epilepsy treatment (15.3%), and difficulty with daily management of epilepsy (13.9%). Participants reported likely engagement with the epilepsy community partner via in-person meetings, over the phone, and through social media contacts; however, there were differences between PWE and caregivers regarding preferences for communication. Almost 60% endorsed that they would likely participate in a brief program to learn skills to manage their epilepsy daily. SIGNIFICANCE: Persons with epilepsy in South Carolina continue to have many unmet needs and would access resources, if available, from a state-wide epilepsy community partner via various modes of communication.

Neurodevelopmental and mental health comorbidities in children and adolescents with epilepsy and migraine: a response to identified research gaps.

AIM: To determine the distribution and risk characteristics of comorbid neurodevelopmental and mental health comorbidities among children and adolescents (6-18y) with epilepsy or migraine (i.e. a neurological condition with shared features and potential etiology) compared with lower extremity fracture (LEF). METHOD: This case-control study involved a subset analysis of surveillance data in South Carolina, USA. Hospital admission, outpatient, and emergency department visits for individuals with an International Classification of Disease, 9th revision Clinical Modification diagnosis of epilepsy (n=6730; 54.5% females, 45.5% males; mean age [SD] 14y 2mo [4y 5mo]); migraine (n=10 495; 74.5% females, 25.5% males; 15y 6mo [2y 6mo]), or LEF (n=15 305; 40.3% females, 59.7% males; 13y 11mo [2y 11mo]) from January 1 2000 to December 31 2011 were identified. The association of epilepsy, migraine, or LEF with any mental health comorbidity was evaluated with univariate and multivariate polytomous logistic regression. RESULTS: Comorbidities were highly prevalent in children and adolescents, with epilepsy with a rate of 29.7% (95% confidence interval [CI]: 28.6-30.8) for mental health comorbidities and 30.8% (95% CI: 29.7-31.9) for neurodevelopmental comorbidities. The odds of mental health comorbidity was 2.20 (95% CI: 2.02-2.39) for children and adolescents with epilepsy and 1.60 (95% CI: 1.48-1.73) for migraine, in reference to children and adolescents with LEF after adjusting for potential confounders. Prevalence and risk for specific comorbidities are presented. INTERPRETATION: Neuropathophysiological and psychosocial factors specific to epilepsy may provide more risk for adolescents with epilepsy compared to migraine.

Risk of venous thromboembolism in people with epilepsy.

OBJECTIVE: Risk of venous thromboembolism (VTE) among people with epilepsy (PWEs) has not been previously reported. Standard VTE prevention methods may increase the risk of complications in this population. This statewide study assessed the risk of VTE in PWEs. METHODS: Main risk categories were grouped into definite epilepsy (DE), probable epilepsy (PE), and migraine, a comparable neurologic condition. All inpatient, emergency department, and hospital-based outpatient encounters in South Carolina from January 1, 2000 through December 31, 2011, were evaluated for the primary outcome variable of VTE, defined as having a diagnosis of VTE at or after the diagnosis of epilepsy or migraine. Coagulopathies and common comorbidities of epilepsy were enumerated. Differences in VTE proportions were assessed using 95% confidence intervals (CIs). Association of VTE with epilepsy and migraine was evaluated with Cox proportional hazard modeling. RESULTS: A total of 138,497 people with migraine (PWMs) and 67,900 PWEs (32,186 DE, 35,714 PE) were included. VTE occurred in 2.7% of PWEs (4.2% among DE), and 0.6% of PWMs. The hazard ratio for VTE in DE compared with PWMs was 3.08 (95% CI 2.76-3.42), adjusted for all covariables. Higher numbers of comorbidities were strongly associated with VTE. PWE had higher numbers of comorbidities (52% with 2+ comorbidities versus 23% of PWM), but the impact of comorbidities on VTE risk was larger in PWM. SIGNIFICANCE: Higher VTE risk in PWE than PWM suggests risk factors associated with epilepsy, independent of chronic neurologic illness. VTE occurrence in PWE is comparable to published rates among people with cancer.

Premature deaths among children with epilepsy - South Carolina, 2000-2011.

Epilepsy is a common childhood neurologic disorder. In 2007, epilepsy affected an estimated 450,000 children aged 0-17 years in the United States. Approximately 53% of children with epilepsy and special health care needs have co-occurring conditions, and only about one third have access to comprehensive care. The few studies of mortality risk among children with epilepsy as compared with the general population generally find a higher risk for death among children with epilepsy with co-occurring conditions but a similar risk for death among children with epilepsy with no co-occurring conditions. However, samples from these mortality studies are often small, limiting comparisons, and are not representative. This highlights the need for expanded mortality surveillance among children with epilepsy to better understand their excess mortality. This report describes mortality among children with epilepsy in South Carolina during 2000-2011 by demographic characteristics and underlying causes of death. The overall mortality rate among children with epilepsy was 8.8 deaths per 1,000 person-years, and the annual risk for death was 0.84%. Developmental conditions, cardiovascular disorders, and injuries were the most common causes of death among children with epilepsy. Team-based care coordination across medical and nonmedical systems can improve outcomes and reduce health care costs for children with special health care needs, but they require more study among children with epilepsy. Ensuring appropriate and timely health care and social services for children with epilepsy, especially those with complications, might reduce the risk for premature death. Health care providers, social service providers, advocacy groups and others can work together to assess whether coordinated care can improve outcomes for children with epilepsy.

Risk of severe and repetitive traumatic brain injury in persons with epilepsy: a population-based case-control study.

BACKGROUND: While traumatic brain injury (TBI) can lead to epilepsy, individuals with preexisting epilepsy or seizure disorder (ESD), depending on the type of epilepsy and the degree of seizure control, may have a greater risk of TBI from seizure activity or medication side effects. The joint occurrence of ESD and TBI can complicate recovery as signs and symptoms of TBI may be mistaken for postictal effects. Those with ESD are predicted to experience more deleterious outcomes either because of having a more severe TBI or because of the cumulative effects of repetitive TBI. METHODS: We conducted a case-control study of all emergency department visits and hospital discharges for TBI from 1998 through 2011 in a statewide population. The severity of TBI, repetitive TBI, and other demographic and clinical characteristics were compared between persons with TBI with preexisting ESD (cases) and those without (controls). Significant differences in proportions were evaluated with confidence intervals. Logistic regression was used to examine the association of the independent variables with ESD. RESULTS: During the study period, 236,164 individuals sustained TBI, 5646 (2.4%) of which had preexisting ESD. After adjustment for demographic and clinical characteristics, cases were more likely to have sustained a severe TBI (OR=1.49; 95% CI=1.38-1.60) and have had repetitive TBI (OR=1.54; 95% CI=1.41-1.69). CONCLUSION: The consequences of TBI may be greater in individuals with ESD owing to the potential for a more severe or repetitive TBI. Seizure control is paramount, and aggressive management of comorbid conditions among persons with ESD and increased awareness of the hazard of repetitive TBI is warranted. Furthermore, future studies are needed to examine the long-term outcomes of cases in comparison with controls to determine if the higher risk of severe or repetitive TBI translates into permanent deficits.

Accelerated death rate in population-based cohort of persons with traumatic brain injury.

OBJECTIVES: To determine the influence of preexisting heart, liver, kidney, cancer, stroke, and mental health problems and examine the influence of low socioeconomic status on mortality after discharge from acute care facilities for individuals with traumatic brain injury. PARTICIPANTS: Population-based retrospective cohort study of 33695 persons discharged from acute care hospital with traumatic brain injury in South Carolina, 1999-2010. MAIN MEASURES: Days elapsing from the dates of injury to death established the survival time (T). Data were censored at the 145th month. Multivariable Cox regression was used to examine the independent effect of the variables on death. Age-adjusted cumulative probability of death for each chronic disease of interest was plotted. RESULTS: By the 70th month of follow-up, rate of death was accelerated from 10-fold for heart diseases to 2.5-fold for mental health problems. Adjusted hazard ratios for diseases of the heart (2.13), liver-renal (3.25), cancer (2.64), neurological diseases and stroke (2.07), diabetes (1.89), hypertension (1.43), and mental health problems (1.59) were highly significant (each with P < .001). Compared with persons with private insurance, the hazard ratio was significantly elevated with Medicaid (1.67), Medicare (1.54), and uninsured (1.27) (each with P < .001). CONCLUSION: Specific chronic diseases strongly influenced postdischarge mortality after traumatic brain injury. Low socioeconomic status as measured by the type of insurance elevated the risk of death.

Abusive head trauma in young children: a population-based study.

OBJECTIVE: The objectives of this study were to provide population-based incidence estimate of abusive head trauma (AHT) in children aged 0 to 5 years from inpatient and emergency department (ED) and identify risk characteristics for recognizing high-risk children to improve public health surveillance. METHODS: This was a retrospective cohort study based on children's first encounter in ED or hospital admission with a diagnosis of head trauma (HT), 2000-2010. The relationship between clinical markers and AHT was examined controlling for covariables in the model using Cox hazards regression. Kaplan-Meier incidence probability was plotted, and the number of weeks elapsing from date of birth to the first encounter with HT established the survival time (T). RESULTS: Twenty-six thousand six hundred eighty-one children had HT, 502 (1.8%) resulted from abuse; 42.4% was captured from ED. Incidence varied from 28.9 (95% confidence interval [CI], 27.9-37.4) in infants to 4.1 (95% CI, 2.4-5.7) in 5-year-olds per 100,000 per year. Adjusted hazard ratio was 20.3 (95% CI, 10.9-38.0) for intracranial bleeding and 11.4 (95% CI, 8.57-15.21) for retinal hemorrhage. CONCLUSIONS: Incidence estimates of AHT are incomplete without including ED. Intracranial bleeding is a cardinal feature of AHT to be considered in case ascertainment to improve public health surveillance.

Risk of death after hospital discharge with traumatic spinal cord injury: a population-based analysis, 1998-2009.

OBJECTIVE: To investigate risk factors associated with mortality among people with traumatic spinal cord injury (TSCI) after discharge from acute care hospitals in South Carolina and to compare their mortality experiences with the general population. DESIGN: Retrospective cohort study. SETTING: Sixty-two acute care, nonfederal hospitals. PARTICIPANTS: Persons (N=2685) with TSCI. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Death after TSCI from all causes within 4288 days of observation after discharge from acute care facilities. RESULTS: The crude annual mortality rate during the period was 33 per 1000 person-years. Number of comorbidities, admission into trauma centers, advancing age, type of insurance, injury level and completeness, and being a man were significantly associated (P<.05) with the risk of death after discharge from acute care facilities. The overall mortality rate of our cohort is 3.6 times (95% confidence interval, 3.3-3.9) higher than the general population. CONCLUSIONS: The causes of postdischarge deaths are multifactorial, and more emphasis should be placed on managing and monitoring chronic diseases throughout the recovery process to improve the survivorship of people with TSCI.

Intracranial bleeding is a cardinal feature of AHT to be considered in case ascertainment to improve public health surveillance.

Baseline prevalence of heart diseases, hypertension, diabetes, and obesity in persons with acute traumatic spinal cord injury: potential threats in the recovery trajectory.

BACKGROUND: Chronic diseases impede the recovery trajectory of acutely injured persons with traumatic spinal cord injury (TSCI). This study compares the odds of prevalent heart disease, hypertension, diabetes mellitus, and obesity between persons with TSCI and persons with lower extremity fractures (LEF) who were discharged from acute care facilities. METHODS: 1,776 patients with acute TSCI (cases) and 1,780 randomly selected patients with LEF (controls) discharged from January 1, 1998, through December 31, 2009, from all nonfederal hospitals were identified. Data extracted from uniform billing files were compared between cases and controls in a multivariable logistic regression model controlling for sociodemographic and clinical covariables. RESULTS: Thirty percent of patients with acute TSCI had at least 1 of 4 conditions compared with 18% of patients with LEF (P < .0001). Persons with acute TSCI were 4 times more likely (odds ratio [OR], 4.05; 95% CI, 1.65-9.97) to have obesity, 2.7 times more likely to have heart disease (P < .001), 2 times more likely to have hypertension (P < .001), and 1.7 times more likely to have diabetes (P = .044) at the onset of TSCI. Disproportionately more Blacks than Whites have TSCI and chronic diseases. CONCLUSION: This study suggests that there is an increased burden of cardiovascular and cardiometabolic diseases among persons with acute TSCI compared with LEF trauma controls. Unattended comorbid conditions will affect quality of life and the recovery process. This warrants continuous monitoring and management of chronic diseases during the rehabilitation process.

Standards for epidemiologic studies and surveillance of epilepsy.

Worldwide, about 65 million people are estimated to have epilepsy. Epidemiologic studies are necessary to define the full public health burden of epilepsy; to set public health and health care priorities; to provide information needed for prevention, early detection, and treatment; to identify education and service needs; and to promote effective health care and support programs for people with epilepsy. However, different definitions and epidemiologic methods complicate the tasks of these studies and their interpretations and comparisons. The purpose of this document is to promote consistency in definitions and methods in an effort to enhance future population-based epidemiologic studies, facilitate comparison between populations, and encourage the collection of data useful for the promotion of public health. We discuss: (1) conceptual and operational definitions of epilepsy, (2) data resources and recommended data elements, and (3) methods and analyses appropriate for epidemiologic studies or the surveillance of epilepsy. Variations in these are considered, taking into account differing resource availability and needs among countries and differing purposes among studies.
