Maternal Gestational Weight Gain in Relation to Antidepressant Continuation in Pregnancy.

OBJECTIVE: Both excessive and inadequate gestational weight gain (GWG) are associated with adverse health outcomes for the woman and her child. Antidepressant use in pregnancy could affect GWG, based on evidence in nonpregnant women that some antidepressants may cause weight gain and others weight loss. Previous studies of antidepressant use and GWG were small with limited ability to account for confounding, including by maternal mental health status and severity. We assessed the association of antidepressant continuation in pregnancy with GWG among women using antidepressants before pregnancy. STUDY DESIGN: Our retrospective cohort study included singleton livebirths from 2001 to 2014 within Kaiser Permanente Washington, an integrated health care system. Data were obtained from electronic health records and linked Washington State birth records. Among women with ≥1 antidepressant fill within 6 months before pregnancy, women who filled an antidepressant during pregnancy were considered "continuers;" women without a fill were "discontinuers." We calculated mean differences in GWG and relative risks (RR) of inadequate and excessive weight gain based on Institute of Medicine guidelines. Using inverse probability of treatment weighting with generalized estimating equations, we addressed differences in maternal characteristics, including mental health conditions. RESULTS: Among the 2,887 births, 1,689 (59%) were to women who continued antidepressants in pregnancy and 1,198 (42%) were to discontinuers. After accounting for confounding, continuers had similar weight gain to those who discontinued (mean difference: 1.3 lbs, 95% confidence interval [CI]: -0.1 to 2.8 lbs) and similar risks of inadequate and excessive GWG (RR: 0.95, 95% CI: 0.80-1.14 and RR: 1.06, 95% CI: 0.98-1.14, respectively). Findings were comparable for specific antidepressants and trimesters of exposure. CONCLUSION: We did not find evidence that continuation of antidepressants in pregnancy led to differences in GWG. KEY POINTS: · Antidepressant use is associated with weight change in nonpregnant populations.. · Prior evidence on whether antidepressant use in pregnancy affects gestational weight gain is sparse.. · We accounted for confounding by characteristics such as mental health conditions and their severity.. · We found no association between pregnancy antidepressant continuation and gestational weight gain..

Antidepressant continuation in pregnancy and risk of gestational diabetes.

PURPOSE: Previous studies observed modestly higher risk of gestational diabetes (GDM) associated with antidepressant use in pregnancy, potentially due to confounding by indication. We assessed the association of antidepressant continuation in pregnancy with GDM, as well as blood glucose levels, after accounting for confounding. METHODS: We conducted a retrospective cohort study of singleton live births from 2001 to 2014 to women enrolled in Kaiser Permanente Washington, an integrated health care delivery system, utilizing electronic health data and linked Washington State birth records. We required that women have ≥1 antidepressant prescription fills ≤6 months before pregnancy. Women with an antidepressant fill during pregnancy were categorized as "continuers" (n = 1634); those without a fill were "discontinuers" (n = 1211). We calculated relative risks (RRs) for GDM and mean differences in screening blood glucose levels using generalized estimating equations with inverse probability of treatment weighting to account for baseline characteristics, including mental health conditions and indicators of mental health severity. RESULTS: Compared with discontinuers, antidepressant continuers had comparable risk of GDM (RR: 1.10; 95% confidence interval [CI], 0.84-1.44) and blood glucose levels (mean difference: 2.3 mg/dL; 95% CI, -1.5 to 6.1 mg/dL). We observed generally similar results for specific antidepressants, with the potential exceptions of risk of GDM associated with sertraline (RR: 1.30; 95% CI, 0.90-1.88) and venlafaxine (RR: 1.52; 95% CI, 0.87-2.68), but neither association was statistically significant. CONCLUSIONS: Our study suggests that overall, women who continue antidepressants in pregnancy are not at increased risk for GDM or higher blood glucose, although further study may be warranted for sertraline and venlafaxine.

Morbidity and Mortality Differences Between Hematopoietic Cell Transplantation Survivors and Other Cancer Survivors.

Purpose To compare the risks of serious health outcomes among hematopoietic cell transplantation (HCT) survivors versus a matched population of patients with cancer who did not undergo HCT, where the primary difference may be exposure to HCT. Methods Two-year HCT survivors treated at a comprehensive cancer center from 1992 through 2009 who were Washington State residents (n = 1,792; 52% allogeneic and 90% hematologic malignancies) were frequency matched by demographic characteristics and underlying cancer diagnosis (as applicable) to non-HCT 2-year cancer survivors, using the state cancer registry (n = 5,455) and the general population (n = 16,340) using driver's license files. Late outcomes for all three cohorts were ascertained from the state hospital discharge and death registries; subsequent cancers were ascertained from the state cancer registry. Results After median follow-up of 7.1 years, HCT survivors experienced significantly greater rates of hospitalization compared with matched non-HCT cancer survivors (280 v 173 episodes per 1,000 person-years, P < .001) and greater all-cause mortality (hazard ratio [HR], 1.1; 95% CI, 1.01 to 1.3). HCT survivors had more hospitalizations or death with infections (10-year cumulative incidence, 31% v 22%; HR, 1.4; 95% CI, 1.3 to 1.6) and respiratory complications (cumulative incidence, 27% v 20%; HR, 1.4; 95% CI, 1.2 to 1.5). Risks of digestive, skin, and musculoskeletal complications also were greater among HCT versus non-HCT cancer survivors. The two groups had similar risks of circulatory complications and second cancers. Both HCT and non-HCT cancer survivors had significantly greater 10-year cumulative incidences of all major organ-system outcomes versus the general population. Conclusion History of HCT was associated with late morbidity and mortality among cancer survivors. In particular, clinicians who care for HCT survivors should be aware of their high rates of late respiratory and infectious complications.

Cardiovascular hospitalizations and mortality among recipients of hematopoietic stem cell transplantation.

BACKGROUND: Hematopoietic stem cell transplantation (HSCT) is increasingly used to treat multiple malignant and nonmalignant conditions. The risk for cardiovascular disease after the procedure has not been well-described. OBJECTIVE: To compare rates and hazards of cardiovascular-related hospitalization and death among persons who were still alive at least 2 years after HSCT with those in a population-based sample. DESIGN: Retrospective cohort study. SETTING: Comprehensive cancer center. PATIENTS: 1491 patients who had survived 2 years or longer after HSCT received between 1985 and 2006, and frequency-matched persons who were randomly selected from drivers' license files in the state of Washington. MEASUREMENTS: Cardiovascular hospitalizations and death, as determined from statewide hospital discharge records and death registries in Washington. RESULTS: Compared with the general population, transplant recipients experienced increased cardiovascular death (adjusted incidence rate difference, 3.6 per 1000 person-years [95% CI, 1.7 to 5.5]). Recipients also had an increased cumulative incidence of ischemic heart disease, cardiomyopathy or heart failure, stroke, vascular diseases, and rhythm disorders and an increased incidence of related conditions that predispose toward more serious cardiovascular disease (hypertension, renal disease, dyslipidemia, and diabetes). No consistent differences in hazards were observed after total-body irradiation or receipt of an allogeneic versus an autologous graft, aside from an increased rate of hypertension among recipients of allogeneic grafts. Disease relapse after transplantation was associated with an increased hazard of cardiovascular death (hazard ratio, 2.3 [CI, 1.1 to 4.8]). LIMITATION: All patients received HSCT at a single institution, and no information was available on pretransplantation treatment and lifestyle factors that may influence risk for cardiovascular disease. CONCLUSION: Increased rates of cardiovascular disease should be taken into account when caring for patients who have received HSCT. Future efforts should be directed toward improved screening and controlling of factors that predispose toward cardiovascular disease.

The association of temporomandibular disorder pain with history of head and neck injury in adolescents.

AIMS: To evaluate the risk of self-reported temporomandibular disorder (TMD) pain among adolescents in relation to previous head and/or neck injury. METHODS: 3,101 enrollees (11 to 17 years of age) of a nonprofit integrated health-care system were interviewed by telephone. Two hundred four cases with self-reported TMD pain and 194 controls without self-reported TMD pain frequency-matched to the cases by age and gender completed standardized in-person interviews and physical examinations in which reports of previous head/neck injuries were recorded. Odds ratio (OR) estimates and 95% confidence intervals (CIs) of the relative risks of TMD pain associated with prior head and/or neck injuries were calculated using logistic regression. RESULTS: A greater proportion of subjects reporting TMD pain (36%) than controls (25%) had a history of head and/or neck injuries (OR = 1.8, 95% CI, 1.1-2.8). In a separate analysis, the presence of TMD based upon the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) was assessed in relation to prior head and/or neck injury. Cases reporting TMD pain and meeting the RDC/TMD criteria for myofascial pain and/or arthralgia or arthritis were 2.0 (CI, 1.0-3.8) times more likely to have had a prior head injury than were controls with neither self-reported nor RDC/TMD pain diagnoses. CONCLUSION: The results suggest a modest association of prior head injuries with both self-reported and clinically diagnosed TMD pain in adolescents.

Neonatal jaundice in Asian, white, and mixed-race infants.

BACKGROUND: East Asians have inherently higher bilirubin levels at birth than whites. The potential for unnecessary treatment makes jaundice a problem of public health and clinical significance. OBJECTIVES: To report the occurrence of jaundice diagnoses in East Asian and mixed East Asian/white infants in Washington State in recent years, and to compare the risk of diagnosis with neonatal jaundice among these infants, relative to white infants. DESIGN: Population-based cohort study in Washington state. Participants were infants of full East Asian parentage (n = 3000), maternal Asian parentage (n = 2997), paternal Asian parentage (n = 2048), and white parentage (n = 3000). Diagnoses of jaundice and "severe jaundice" were identified using International Classification of Diseases, Ninth Revision (ICD-9) diagnosis and procedure codes from hospital discharge records. RESULTS: Infants of full East Asian parentage were more likely to be diagnosed with jaundice than were white infants (relative risk [RR], 1.37; 95% confidence interval [CI], 1.16-1.62). For infants with Asian mothers and white fathers, the RR was 1.09 (95% CI, 0.91-1.30). Infants with Asian fathers and white mothers had an RR of 1.26 (95% CI, 1.05-1.52). The risk of severe jaundice requiring phototherapy, blood transfusion, or rehospitalization, however, was significantly elevated only for infants of full East Asian parentage (RR, 1.7; 95% CI, 1.12-2.58). CONCLUSIONS: Diagnoses of neonatal jaundice occurred more often among East Asian and mixed Asian/white infants than among white infants. However, the risk of jaundice requiring extended hospital stay, rehospitalization, phototherapy, or blood transfusion was elevated only for infants of full East Asian parentage.
