Housing for All: Addressing the Housing Needs of Massachusetts\u27 North Shore Residents

The aim of this report is to support North Shore efforts to build a regional approach to housing. The report explores the housing needs of people who are caught in the squeeze between low incomes and high housing costs. The report has two goals: to provide information for understanding the need to expand below market rate housing; to illustrate that need by providing detailed documentation on the situation in Gloucester, Peabody, and Salem. The report is not intended to propose solutions, but to provide groundwork for solutions

Differentiating Acute Rejection From Preeclampsia After Kidney Transplantation.

OBJECTIVE: To evaluate the clinical and laboratory characteristics in pregnancy that differentiate preeclampsia from acute renal allograft rejection and to investigate the maternal, neonatal, and graft sequelae of these diagnoses. METHODS: We conducted a retrospective case-controlled registry study of data abstracted from Transplant Pregnancy Registry International deliveries between 1968 and 2019. All adult kidney transplant recipients with singleton pregnancies of at least 20 weeks of gestation were included. Acute rejection was biopsy proven and preeclampsia was diagnosed based on contemporary criteria. Variables were compared using χ2, Fisher exact, and Wilcoxon rank sum tests as appropriate. Multivariable linear regression was used to analyze preterm birth. Kaplan-Meier curves with log-rank test and Cox proportional hazards model were used to compare graft loss over time. RESULTS: There were 26 pregnant women with biopsy-confirmed acute rejection who were matched by the year they conceived to 78 pregnant women with preeclampsia. Recipients with acute rejection had elevated peripartum serum creatinine levels (73% vs 14%, P CONCLUSION: In pregnancy, acute rejection is associated with higher creatinine levels, and preeclampsia is associated with increased proteinuria. Acute rejection in pregnancy carries a risk of prematurity and graft loss beyond that of preeclampsia for kidney transplant recipients.

Emergent Prelabor Cesarean Birth in Solid Organ Transplant Recipients: Associated Risk Factors and Outcomes.

BACKGROUND: Pregnancies after solid-organ transplant are at a higher risk for antepartum admission and pregnancy complications, including cesarean birth. Emergent prelabor cesarean is associated with increased maternal and neonatal morbidity in other high-risk populations, but its incidence and impact in transplant recipients is not well understood OBJECTIVE: To characterize the risk factors and outcomes of emergency prelabor cesarean birth in kidney and liver transplant recipients STUDY DESIGN: Retrospective cohort study of all kidney and liver transplant recipients \u3e20 weeks\u27 gestation enrolled in the Transplant Pregnancy Registry International between 1976 and 2019. Participants admitted antepartum who required an emergency prelabor cesarean were compared to those admitted antepartum who underwent non-emergent birth. Primary outcomes were composite severe maternal morbidity and neonatal composite morbidity. Multivariable logistic regression was conducted for neonatal composite morbidity RESULTS: Of 1,979 births, 181 pregnancies (188 neonates) with an antepartum admission were included. 51 pregnancies (53 neonates, 28%) were delivered by emergent prelabor cesarean birth compared with 130 pregnancies (135 neonates, 72%) admitted antepartum who subsequently did not require emergent delivery. The most common indication for emergent delivery was non-reassuring fetal heart tracing (44 neonates, 86%). Pregnant people who underwent an emergent prelabor cesarean were less likely to birth at a transplant center (37.3% vs 41.5%, p=0.04) and had increased rates of chronic hypertension (33.3% vs 16.2%, p=0.02). There was no significant difference in severe maternal morbidity (3.9% vs 4.6%, p=0.84), though there was an increase in surgical site infection in the emergent prelabor cesarean cohort (3.9% vs 0%, p=0.02). Among those with an emergent prelabor cesarean, there was a significant increase in neonatal composite morbidity (43.4% vs 19.3%,

A streamlined mass spectrometry-based proteomics workflow for large scale FFPE tissue analysis

Formalin fixation and paraffin-embedding (FFPE) is the most common method to preserve human tissue for clinical diagnosis, and FFPE archives represent an invaluable resource for biomedical research. Proteins in FFPE material are stable over decades but their efficient extraction and streamlined analysis by mass spectrometry (MS)-based proteomics has so far proven challenging. Herein we describe a MS-based proteomic workflow for quantitative profiling of large FFPE tissue cohorts directly from histopathology glass slides. We demonstrate broad applicability of the workflow to clinical pathology specimens and variable sample amounts, including low-input cancer tissue isolated by laser microdissection. Using state-of-the-art data dependent acquisition (DDA) and data independent acquisition (DIA) MS workflows, we consistently quantify a large part of the proteome in 100 min single-run analyses. In an adenoma cohort comprising more than 100 samples, total workup took less than a day. We observed a moderate trend towards lower protein identification in long-term stored samples (>15 years), but clustering into distinct proteomic subtypes was independent of archival time. Our results underscore the great promise of FFPE tissues for patient phenotyping using unbiased proteomics and they prove the feasibility of analyzing large tissue cohorts in a robust, timely, and streamlined manner

The 25th Anniversary of the National Transplantation Pregnancy Registry.

The National Transplantation Pregnancy Registry (NTPR) is a unique resource for comprehensive information about parenthood after transplantation. To date, 1461 female solid organ transplant recipients with 2609 pregnancies and 879 male recipients who fathered 1358 pregnancies have participated in the NTPR. Over the first 25 years of the NTPR, pregnancy after transplantation has progressed from a situation where termination was once advised, to a topic of pre-transplant counselling with likelihood for success if established criteria are met. Pregnancy after transplantation remains high-risk; it should be carefully considered, planned, and monitored by a multidisciplinary health care team. Pregnancy and maternal outcomes vary based on multiple factors, especially on the type of organ transplanted and the pre-pregnancy graft function. As an open-ended condition-based study, the NTPR accumulates a vast amount of data that is used for comparisons that measure the reliability and benefits of treatments and for developing state-of-the-art management guidelines based on a review of current practices at participating transplant centers. NTPR data analyses have contributed to quantifying issues surrounding post-transplant parenthood such as location of the transplanted organ in proximity to the developing fetus, the safety of various immunosuppressive regimens for pregnancy and fatherhood, the teratogenicity of maternal exposure to mycophenolate during pregnancy, the advisability and timing of planning a posttransplant pregnancy, the dosing of medications during pregnancy, the incidence and treatment of comorbidities during pregnancy, and the effect of in utero or breast milk exposure to immunosuppressants on the developing child. As the face of transplantation evolves, the NTPR will continue to collect and disseminate information to assist recipients and their healthcare providers in making informed decisions about the advisability of pregnancy and care for those who choose to become parents after a solid organ transplant. To insure the continued success of our study, all transplant centers and recipients are encouraged to contact the NTPR to report any post-transplant pregnancy
