Background: Maternal education has been shown repeatedly to be inversely associated with preterm birth. Both preterm birth and educational level of families are correlated across generations, but it is not clear if educational level of grandparents affects the risk of preterm delivery of their grandchildren, and, if so, if the association with grandmother's education is independent of mother's education.

Methods: We used New Jersey birth certificates to create a transgenerational dataset to examine the effect of grandmother's education on risk of PTB in White, Black and Hispanic grandchildren.

Article Synopsis
  • The study examines the survival rates of elderly women with breast cancer, focusing on those with preexisting severe mental illness.
  • Nearly 3% of the studied cohort had severe mental illness, which was linked to a two-fold increase in all-cause mortality compared to those without mental illness.
  • While breast cancer-specific mortality also showed some increase, it wasn't statistically significant; patients with severe mental illness tended to have more advanced cancer and associated health risks, highlighting the need for tailored medical support.

Article Synopsis
  • The study investigates how comorbidity impacts breast cancer survival rates across different races, focusing on women diagnosed with breast cancer.
  • A retrospective analysis examined data from over 68,000 women aged 66 and older, assessing their health conditions prior to cancer diagnosis and tracking survival until 2010.
  • Results indicated that while comorbid conditions did not negatively affect survival for black women, diabetes was linked to higher mortality and worse tumor characteristics in white women, highlighting the need for further research on the diabetes-breast cancer relationship.

Background: The incidence rates of ischemic stroke and ST-segment elevation myocardial infarction (STEMI) have decreased significantly in the United States since 1950. However, there is evidence of flattening of this trend or increasing rates for stroke in patients younger than 50 years. The objective of this study was to examine the changes in incidence rates of stroke and STEMI using an age-period-cohort model with statewide data from New Jersey.

To evaluate the effect of skin self-examination (SSE) on melanoma mortality, we estimated the survival for individuals performing SSE compared with those who did not. Participants were from a previously carried out case-control study, who were newly diagnosed melanoma cases in 1987-1989. A 20-year survival analysis was carried out using death (event) and other causes of death (competing).

Background: Blood transfusion might affect long-term mortality by changing immune function and thus potentially increasing the risk of subsequent infections and cancer recurrence. Compared with a restrictive transfusion strategy, a more liberal strategy could reduce cardiac complications by lowering myocardial damage, thereby reducing future deaths from cardiovascular disease. We aimed to establish the effect of a liberal transfusion strategy on long-term survival compared with a restrictive transfusion strategy.

Purpose: To examine the role of preoperative magnetic resonance imaging (pMRI) on time to surgery and rates of reoperation and contralateral prophylactic mastectomy (CPM) using a population-based study of New Jersey breast cancer patients.

Methods: The study included 289 African-American and 320 white women who participated in the Breast Cancer Treatment Disparity Study and underwent breast surgery for newly diagnosed early-stage breast cancer between 2005 and 2010. Patients were identified through rapid case ascertainment by the New Jersey State Cancer Registry.

Objective: Delays in treatment initiation may contribute to the poorer breast cancer survival among Black women compared with Whites. Lower socioeconomic status and lack of access to care are other reasons for the observed disparities. We, therefore, examined racial differences in treatment delays for early breast cancer in a similarly insured population of Medicaid beneficiaries.

The purpose of the present study was to examine the risk of stillbirth associated with ambient air pollution during pregnancy. Using live birth and fetal death data from New Jersey from 1998 to 2004, the authors assigned daily concentrations of air pollution to each birth or fetal death. Generalized estimating equation models were used to estimate the relative odds of stillbirth associated with interquartile range increases in mean air pollutant concentrations in the first, second, and third trimesters and throughout the entire pregnancy.

Background: Statins are some of the most commonly prescribed medications in medical practice, and prostate cancer is the most common malignancy among men. Although there has been no consistent evidence that statins affect cancer incidence, including prostate cancer, several reports suggest they may decrease the rate of advanced prostate cancer. However, no study to date has specifically examined statin use and prostate cancer mortality.

Black breast cancer patients have shorter survival compared to whites. Lack of optimal treatment may be a potential explanation for this difference. Although racial disparities in surgical and radiation therapy have been studied extensively, there is little information on racial disparities in use of adjuvant systemic therapy.
