Population-Based Study of Risk of AKI with Levetiracetam

Background and objectivesRegulatory agencies warn about the risk of AKI with levetiracetam use on the basis of information from case reports. We conducted this study to determine whether new levetiracetam use versus nonuse is associated with a higher risk of AKI.Design, setting, participants, & measurementsThis was a population-based retrospective cohort study of adults with epilepsy in Ontario, Canada. Patients who received a new outpatient prescription for levetiracetam between January 1, 2004 and March 1, 2017 were matched to two nonusers on stage of CKD, recorded seizure in the prior 90 days, and logit of a propensity score for levetiracetam use. The primary outcome was a hospital encounter (emergency department visit or hospitalization) with AKI within 30 days of cohort entry. Secondary outcomes were AKI within 180 days and change in the concentration of serum creatinine. We assessed the primary outcome using health care diagnosis codes. We evaluated the change in the concentration of serum creatinine in a subpopulation with laboratory measurements.ResultsWe matched 3980 levetiracetam users to 7960 nonusers (mean age 55 years, 51% women). Levetiracetam use was not significantly associated with a higher risk of AKI within 30 days (13 [0.33%] events in levetiracetam users and 21 [0.26%] events in nonusers [odds ratio, 1.24; 95% confidence interval, 0.62 to 2.47]). Similarly, there was no significant association with AKI within 180 days (odds ratio, 0.70; 95% confidence interval, 0.43 to 1.13). The change in the concentration of serum creatinine did not significantly differ between levetiracetam users and nonusers.ConclusionsIn this population-based study levetiracetam use was not associated with a higher risk of AKI.PodcastThis article contains a podcast at https://www.asn-online.org/media/podcast/CJASN/2018_12_11_Yau_Podcast.mp3

Singleton Birth

Objective The aim of the study is to evaluate the effect of the coronavirus disease 2019 (COVID-19) pandemic national lockdown period on the rate of singleton preterm births in Israel. Study Design This is a population-based cohort study of 3,41,291 singleton infants born in the months of January to July 2017 to 2020. Multivariable logistic regression analyses were used to estimate the influence of period and year on the rates of preterm births during the lockdown period (11th March − 5th May 2020) compared with rates before (January 1st 2020 − March 10th 2020), and after the lockdown (May 6th 2020–June 30th 2020) and to the corresponding periods in 2017to 2019. Results During the lockdown period the preterm birth rate (primary outcome) decreased by 9.7% from 5.05 to 4.56% in the pre-lockdown period (p = 0.006), an adjusted decrease of −0.52% (95% confidence interval −0.89%; −0.15%), odds ratio 0.898 (95% confidence interval 0.832; 0.970). Conclusion The rate of singleton preterm births declined by 9.7% during the COVID-19 pandemic national lockdown period in Israel. Key Points

Conservation Surgery

Background and Aims: In Iceland, oncoplastic breast-conservation surgery has been performed since 2008. The aim of this population-based study was to assess and compare the efficacy and patient satisfaction of standard breast-conservation surgery with oncoplastic breast-conservation surgery. Materials and methods: This is a population-based, retrospective, observational cohort study on all women undergoing breast-conservation surgery in Iceland from the 1 January 2008 to 31 December 2014. A multivariate logistic regression and linear regression were performed to assess differences in outcomes and a patient satisfaction questionnaire was used to assess certain patient-related outcome measures. Results and conclusion: A total of 750 women underwent breast-conserving surgery, 665 had standard breast-conservation surgery and 85 oncoplastic breast-conservation surgery. Oncoplastic breast-conservation surgery was associated with a significantly larger mean size (2.4 cm vs 1.7 cm, p < 0.001) and weight (181.8 g vs 63.4 g, p < 0.001) of breast specimen excised when compared to standard breast-conservation surgery. After correcting for confounding factors, there was no significant difference in surgical margin involvement (odds ratio = 0.97, confidence interval = 0.44–1.97), frequency of complications (odds ratio = 1.06, confidence interval = 0.46–2.18), frequency of reoperations (odds ratio = 0.98; confidence interval = 0.50–1.81), or time to first adjuvant therapy (–0.23 days for oncoplastic breast-conservation surgery, p = 0.95). Patient satisfaction was high in both groups, although not statistically different (96% in oncoplastic breast-conservation surgery group vs 89% in the standard breast-conservation surgery group, p = 0.84). Our results show that oncoplastic breast-conservation surgery is at least as safe as standard breast-conservation surgery in selected cases and may be preferable in ductal carcinoma in situ.

Abstract Context: The association between thyroid function and blood pressure is insufficiently studied. Objective: The objective of the investigation was to study the association between TSH within the reference range and blood pressure. Design and Setting: This was a cross-sectional, population-based study. Subjects: A total of 30,728 individuals without previously known thyroid disease were studied. Main Outcome Measures: The main outcome measures were mean systolic and diastolic blood pressure and pulse pressure and odds ratio for hypertension (>140/90 mm Hg or current or previous use of antihypertensive medication), according to categories of TSH. Results: Within the reference range of TSH (0.50–3.5 mU/liter), there was a linear increase in blood pressure with increasing TSH. The average increase in systolic blood pressure was 2.0 mm Hg [95% confidence interval (CI) 1.4–2.6 mm Hg] per milliunit per liter increase in TSH among men, and 1.8 mm Hg (95% CI 1.4–2.3 mm Hg) in women. The corresponding increase in diastolic blood pressure was 1.6 mm Hg (95% CI 1.2–2.0 mm Hg) in men and 1.1 mm Hg (95% CI 0.8–1.3 mm Hg) in women. Comparing TSH of 3.0–3.5 mU/liter (upper part of the reference) with TSH of 0.50–0.99 mU/liter (lower part of the reference), the odds ratio for hypertension was 1.98 (95% CI 1.56–2.53) in men and 1.23 (95% CI 1.04–1.46) in women. Conclusion: Within the reference range of TSH, we found a linear positive association between TSH and systolic and diastolic blood pressure that may have long-term implications for cardiovascular health.

The Impact

Introduction: Very little is known about the impact of vision impairment (VI) on physical health in late-life in sub-Saharan Africa populations, whereas many older people experience it. We investigated the association between self-reported VI and frailty in Central African older people with low cognitive performance. Methods: It was cross-sectional analysis of data from the Epidemiology of Dementia in Central Africa (EPIDEMCA) population-based study. After screening for cognitive impairment, older people with low cognitive performance were selected. Frailty was assessed using the Study of Osteoporotic Fracture index. Participants who met one of the 3 parameters assessed (unintentional weight loss, inability to do 5 chair stands, and low energy level) were considered as pre-frail, and those who met 2 or more parameters were considered as frail. VI was self-reported. Associations were investigated using multinomial logistic regression models. Results: Out of 2,002 older people enrolled in EPIDEMCA, 775 (38.7%) had low cognitive performance on the screening test. Of them, 514 participants (sex ratio: 0.25) had available data on VI and frailty and were included in the analyses. In total, 360 (70%) self-reported VI. Prevalence of frailty was estimated at 64.9% [95% confidence interval: 60.9%–69.1%] and 23.7% [95% CI: 20.1%–27.4%] for pre-frailty. After full adjustment, self-reported VI was associated with frailty (adjusted odds ratio = 2.2; 95% CI: 1.1–4.3) but not with pre-frailty (adjusted odds ratio = 1.8; 95% CI: 0.9–3.7). Conclusion: In Central African older people with low cognitive performance, those who self-reported VI were more likely to experience frailty. Our findings suggest that greater attention should be devoted to VI among this vulnerable population in order to identify early frailty onset and provide adequate care management.

Background: Dissemination of the Physical Activity Guidelines for Americans (Guidelines) is needed, but how individuals respond to the Guidelines is not well understood. This surveillance study describes US adults’ reported responses to and information sources for hearing about the Guidelines and explores relationships between how respondents heard about the Guidelines and their reported response(s). Methods: Data were analyzed from the population-based 2019 Health Information National Trends Survey 5 Cycle 3. Population-weighted proportions of response were calculated. Among those who had heard about the Guidelines, binary logistic regressions examined associations between the reported response(s) and the information source and number of sources reported. Results: The analytical sample included 5047 adults. Nearly 65% of US adults reported hearing about the Guidelines, and 29% reported a behavioral response (eg, increased physical activity). Hearing about the Guidelines through health professionals (adjusted odds ratio = 2.30, 95% confidence interval, 1.45–3.65) or social media (adjusted odds ratio = 1.89, 95% confidence interval, 1.20–2.96) (vs other sources) was associated with reporting increasing physical activity. Hearing from multiple sources (vs one source) was associated with reporting increasing physical activity (adjusted odds ratio = 1.97, 95% confidence interval, 1.18–3.31). Conclusion: Findings suggest dissemination of the Guidelines across multiple channels may promote greater changes in physical activity.

We investigated the association between post-rewarming fever (PRF) and 6-month neurologic outcomes in cardiac arrest survivors. This was a multicenter study based on a registry of comatose adult (³ 18years) out-of-hospital cardiac arrest (OHCA) survivors who underwent targeted temperature management between October 2015 to December 2018. PRF was defined as peak temperature ≥ 38.0 °C within 72 h after completion of rewarming, and PRF timing was categorized as within 24, 24–48, and 48–72 h epochs. The primary outcome was neurologic outcomes at six months after cardiac arrest. Unfavorable neurologic outcome was defined as cerebral performance categories three to five. A total of 1031 patients were included, and 642 (62.3%) had unfavorable neurologic outcomes. PRF developed in 389 (37.7%) patients in 72 h after rewarming: within 24 h in 150 (38.6%), in 24–48 h in 155 (39.8%), and in 48–72 h in 84 (21.6%). PRF was associated with improved neurologic outcomes (odds ratio (OR), 0.633; 95% confidence interval (CI), 0.416–0.963). PRF within 24 h (OR, 0.355; 95% CI, 0.191–0.659), but not in 24–48 h or 48–72 h, was associated with unfavorable neurologic outcomes. Early PRF within 24 h after rewarming was associated with favorable neurologic outcomes.

AbstractBackgroundAcute kidney injury (AKI) diagnosis requires ascertainment of change from a known baseline. Although pre-admission serum creatinine (SCr) is recommended, to date, all studies of AKI in acute stroke have used the first SCr on admission.MethodsAll patients admitted with an acute stroke to an emergency hospital were recruited. We compared use of pre-admission SCr with admission SCr to diagnose AKI. Regression analyses were used to identify risk factors for 30-day and 1-year mortality, respectively.ResultsA total of 1354 patients were recruited from December 2012 to September 2015. Incidence of AKI was 18.7 and 19.9% using pre-admission SCr and admission SCr, respectively. Diagnosis of AKI was associated with significantly increased 30-day and 1-year mortality. Diagnosis of AKI using pre-admission SCr had a stronger relationship with both 30-day and 1-year mortality. In 443 patients with a pre-admission SCr and at least two SCr during admission, AKI diagnosed using pre-admission SCr had a stronger relationship than AKI diagnosed using admission SCr with 30-day mortality [odds ratio (OR) = 2.64; 95% confidence interval (CI) 1.36–5.12; P = 0.004 versus OR = 2.10; 95% CI 1.09–4.03; P = 0.026] and 1-year mortality [hazard ratio (HR) = 1.90, 95% CI 1.32–2.76; P = 0.001 versus HR = 1.47; 95% CI 1.01–2.15; P = 0.046] in fully adjusted models.ConclusionsAKI after stroke is common and is associated with increased 30-day and 1-year mortality. Using first SCr on admission gives a comparable AKI incidence to pre-admission SCr, but underestimates 30-day and 1-year mortality risk.

Mammographic Screening

Objective: Population-wide mammographic screening programs aim to reduce breast cancer mortality. However, a broad view of the harms and benefits of these programs is necessary to favor informed decisions, especially in the earliest stages of the disease. Here, we compare the outcomes of patients diagnosed with breast ductal carcinoma in situ in participants and non-participants of a population-based mammographic screening program. Methods: A retrospective cohort study of all patients diagnosed with breast ductal carcinoma in situ between 2000 and 2010 within a single hospital. A total of 211 patients were included, and the median follow-up was 8.4 years. The effect of detection mode (screen-detected and non-screen-detected) on breast cancer recurrences, readmissions, and complications was evaluated through multivariate logistic regression analysis. Results: In the majority of women, breast ductal carcinoma in situ was screen-detected (63.5%). Screen-detected breast ductal carcinoma in situ was smaller in size compared to those non-screen-detected (57.53% < 20 mm versus 78.03%, p = 0.002). Overall, breast-conserving surgery was the most frequent surgery (86.26%); however, mastectomy was higher in non-screen-detected breast ductal carcinoma in situ (20.78% versus 9.7%, p = 0.024). Readmissions for mastectomy were more frequent in non-screen-detected breast ductal carcinoma in situ. Psychological complications, such as fatigue, anxiety, and depression, had a prevalence of 15% within our cohort. Risk of readmissions and complications was higher within the non-screen-detected group, as evidenced by an odds ratio = 6.25 (95% confidence interval = 1.95–19.99) for readmissions and an odds ratio = 2.41 (95% confidence interval = 1.95–4.86) for complications. Conclusions: Our findings indicate that women with breast ductal carcinoma in situ breast cancer diagnosed through population-based breast cancer screening program experience a lower risk of readmissions and complications than those diagnosed outside these programs. These findings can help aid women and health professionals make informed decisions regarding screening.

AbstractBackground:Adults with CHD have reduced work participation rates compared to adults without CHD. We aimed to quantify employment rate among adult CHD patients in a population-based registry and to describe factors and barriers associated with work participation.Methods:We retrospectively identified adults with employment information in the North Carolina Congenital Heart Defects Surveillance Network. Employment was defined as any paid work in a given year. Logistic regression was used to examine patients’ employment status during each year.Results:The registry included 1,208 adult CHD patients with a health care encounter between 2009 and 2013, of whom 1,078 had ≥1 year of data with known employment status. Overall, 401 patients (37%) were employed in their most recent registry year. On multivariable analysis, the odds of employment decreased with older age and were lower for Black as compared to White patients (odds ratio = 0.78; 95% confidence interval: 0.62, 0.98; p = 0.030), and single as compared to married patients (odds ratio = 0.50; 95% confidence interval: 0.39, 0.63; p < 0.001).Conclusion:In a registry where employment status was routinely captured, only 37% of adult CHD patients aged 18–64 years were employed, with older patients, Black patients, and single patients being less likely to be employed. Further work is needed to consider how enhancing cardiology follow-up for adults with CHD can integrate support for employment.

Abstract Abstract 1169 Background and objectives Immune thrombocytopenia (ITP) is thought to result from an autoimmune mechanism, and some case-reports have suggested that immunizations could be involved and trigger the autoimmune process. This prospective multicenter case-control study investigated for the first time associations between ITP and vaccination in adults, particularly between ITP and influenza vaccinations. Methods Over a three year period, a network of 15 physicians from hematology and internal medicine referral centers across France recruited newly diagnosed cases of primary ITP in patients aged over 15 years fulfilling the ITP standardized criteria of the American Society of Hematology. Recruiting physicians completed standardized forms for each patient and every patient underwent a standardized 1 hour-interview focused on previous medications and vaccinations in the last 12 months. Incident ITP cases were compared to sex and age-matched controls selected and recruited from general practice settings, also from the same geographically areas of France. The method of referent recruitment has been described elsewhere (Grimaldi-Bensouda et al. 2010 Pharmacoepidemiol Drug Saf 2010;19(6):591–5). Controls were also interviewed in the same standardized way as cases. Cases and control were compared in respect of various descriptive factors and potential risk factors for ITP. Written or other confirmation of vaccinations was sought from both the patient and his/her physician. The time window defining exposure to vaccines was 12 months before the index date. In secondary analysis, the most prevalent vaccines in adults were analyzed. Results Two hundred and twenty four cases fulfilling the inclusion criteria and 4412 were included in the study. Seventy eight of the 224 cases (34.8%) and 1566 of 4412 controls (35.5%) received a vaccination within this time window [adjusted odds ratio 0.97, 95% confidence interval 0.70–1.33]. Twenty percent of the cases and 26% of controls received an influenza vaccine [adjusted odds ratio 0.66, 95% confidence interval 0.45–0.98]. Other prevalent vaccines in adult are currently under study. Conclusions This systematic case-control design is well-suited to study rare disorders such as ITP and few such studies have been conducted. Another advantage was the minimization of recall bias because questions about vaccinations were included in a standardized interview focusing on exposure to all medications. When all vaccines were considered, we found no association between vaccination and the incidence of ITP in either crude or adjusted analyses. Moreover, cases were less likely than controls to have been vaccinated against influenza in the 12 months before the index date.
