Is gravidity associated with COVID-19 vaccination among pregnant women in Jamaica?

Introduction: In 2021, Jamaica's maternal mortality ratio doubled as a result of COVID-19-related deaths. Yet, COVID-19 vaccination among pregnant Jamaican women remained low. In the United States, COVID-19 vaccination is lower among pregnant women who have had multiple pregnancies (multigravidas) versus women who were pregnant for the first time (primigravidas).

Association between acceptance of routine pregnancy vaccinations and COVID-19 vaccine uptake in pregnant patients.

Objective: COVID-19 vaccination is a key approach to reduce morbidity and mortality in pregnant patients and their newborns. Anti-vaccine sentiment has recently increased with unclear impact on pregnant patients. We examined the association between acceptance of tetanus-diphtheria-acellular pertussis (Tdap) and influenza vaccines, considered to be routine pregnancy vaccines, and COVID-19 vaccine acceptance.

Factors Associated With Coronavirus Disease 2019 Vaccine Uptake Among Pregnant Women and Nonpregnant Women of Reproductive Age in Jamaica.

Background: Despite high rates of coronavirus disease 2019 (COVID-19)-related maternal mortality, Jamaica currently has little data on COVID-19 vaccine uptake among pregnant women.

Methods: We conducted a cross-sectional, web-based survey of 192 reproductive-aged women in Jamaica from February 1 to 8, 2022. Participants were recruited from a convenience sample of patients, providers, and staff at a teaching hospital.

Provider confidence in counseling preconception, pregnant, and postpartum patients regarding COVID-19 vaccination: A cross-sectional survey study.

Background And Aims: Healthcare provider counseling surrounding COVID-19 vaccine in pregnancy and lactation is essential to vaccination uptake in this population; however, provider knowledge and confidence are not well characterized. We aimed to assess knowledge and confidence in COVID-19 vaccine counseling among practitioners who provide care to pregnant persons and to describe factors associated with confidence in counseling.

Methods: A web-based anonymous survey was distributed via email to a cross-sectional convenience sample of Obstetrics and Gynecology, Primary Care, and Internal Medicine faculty at three hospitals in a single healthcare network in Massachusetts, United States.

Availability Versus Accessibility: Identifying COVID-19 Testing Deserts Across Massachusetts.

Throughout the COVID-19 pandemic, communities of color have faced significantly higher rates of COVID-19 infection, as well as poor clinical outcomes. These differences are driven by long-standing structural inequities that prevent effective social distancing efforts and are further exacerbated by disparities in COVID-19 testing. Our study applied the concept of "COVID-19 testing deserts" to systematically identify gaps in testing resource allocation across Massachusetts in May 2020 and March 2021.

Evaluating direct detection detectors for short-range order characterization of amorphous materials by electron scattering.

The introduction of direct electron detectors (DEDs) to transmission electron microscopy has set off the 'resolution revolution', especially for cryoTEM low-dose imaging of soft matter. In comparison to traditional indirect electron detectors such as Charged-Coupled Devices (CCD), DEDs show an improved modulation transfer function (MTF) and detective quantum efficiency (DQE) across all spatial frequencies, as well as faster frame rates which enable single electron counting. The benefits of such characteristics for imaging, spectroscopy and electron holography have been demonstrated previously.

Hemodynamic changes in patients with SARS-CoV-2 infection presenting for cesarean delivery under spinal anesthesia: a retrospective case-control study.

Background: Coronavirus disease 2019 (COVID-19) is associated with adverse maternal and neonatal outcomes. Early studies suggested that COVID-19 was associated with a higher incidence of hypotension following neuraxial anesthesia in parturients. We explored the hemodynamic response to spinal anesthesia for cesarean delivery in pregnant severe respiratory distress syndrome-coronavirus-2 (SARS-CoV-2) positive patients, using a retrospective case-control design.

Pulmonary function tests for evaluating the severity of Duchenne muscular dystrophy disease.

Aim: In Duchenne muscular dystrophy (DMD), lung disease contributes significantly to morbidity and mortality. This study aimed to assess the usefulness of various pulmonary function tests in evaluating DMD severity.

Methods: This retrospective study analysed lung function tests of patients with DMD-treated in the multidisciplinary respiratory neuromuscular clinic at Schneiders' Children Medical Center of Israel.

Medical Students' Intention to Change After Receiving Formative Feedback: Employing Social Cognitive Theories of Behavior.

Introduction: We applied Azjen's theory of planned behavior (TPB) and Triandis' theory of interpersonal behavior (TIB) to understand medical students' intention to change behavior based on feedback received during an obstetrics and gynecology clerkship. Both models presume that behavioral intention is strongly related to actual behavior.

Materials And Methods: We collected free-text responses from students during a year-long initiative on the obstetrics and gynecology clerkship at Harvard Medical School.

Experiences Navigating the Pregnancy Care Continuum During the COVID-19 Pandemic.

Introduction: The COVID-19 pandemic led to unprecedented changes in care delivery across the pregnancy care continuum. Our primary objective with this research was to characterize the range of ways that the early months of the COVID-19 pandemic affected pregnancy, childbirth, and postpartum care experiences.

Methods: Pregnant and recently pregnant patients (n = 20) from obstetrics and gynecology clinical sites associated with Massachusetts General Hospital were interviewed about their experiences with prenatal care, childbirth, and postpartum care during the first wave of the COVID-19 pandemic.

From nanoparticles to crystals: one-pot programmable biosynthesis of photothermal gold structures and their use for biomedical applications.

Inspired by nature, green chemistry uses various biomolecules, such as proteins, as reducing agents to synthesize metallic nanostructures. This methodology provides an alternative route to conventional harsh synthetic processes, which include polluting chemicals. Tuning the resulting nanostructure properties, such as their size and shape, is challenging as the exact mechanism involved in their formation is still not well understood.

Perceptions and Attitudes toward COVID-19 Vaccination among Pregnant and Postpartum Individuals.

Objective: This study aimed to characterize attitudes toward novel coronavirus disease 2019 (COVID-19) vaccination and to evaluate factors associated with vaccine uptake among pregnant individuals.

Study Design: An anonymous survey was distributed to a convenience sample of pregnant individuals receiving prenatal care at two large urban academic hospitals in a single health care network in Massachusetts. Individual demographic variables were included in the survey along with questions assessing attitudes toward COVID-19 and vaccination in pregnancy.

Elastic and inelastic mean free paths for scattering of fast electrons in thin-film oxides.

Quantitative transmission electron microscopy (TEM) often requires accurate knowledge of sample thickness for determining defect density, structure factors, sample dimensions, electron beam and X-ray photons signal broadening. The most common thickness measurement is by Electron Energy Loss Spectroscopy which can be applied effectively to crystalline and amorphous materials. The drawback is that sample thickness is measured in units of Inelastic Mean Free Path (MFP) which depends on the material, the electron energy and the collection angle of the spectrometer.

Emotional Experiences of Pregnant and Postpartum People with Confirmed or Suspected COVID-19 Infection During the Initial Surge of the Pandemic.

Objectives: The COVID-19 pandemic may have a unique emotional impact on pregnant people. This qualitative study aimed to characterize the emotional effects of the COVID-19 pandemic on pregnant and recently pregnant patients who had either suspected or confirmed COVID-19 infection during the initial 6 months of the pandemic.

Methods: Pregnant and recently pregnant participants ( = 20) from Massachusetts General Hospital Obstetrics and Gynecology clinical sites with suspected or confirmed COVID-19 infection were interviewed about their experiences during the COVID-19 pandemic.

First Trimester Cardiac Biomarkers among Women with Peripartum Cardiomyopathy: Are There Early Clues to This Late-Pregnancy Phenomenon?

Objective: Whether biomarkers may enable early identification of women who develop peripartum cardiomyopathy (PPCM) prior to disease onset remains a question of interest.

Study Design: A retrospective nested case-control study was conducted to determine whether first trimester -terminal pro-B type natriuretic peptide (NT-proBNP) or high sensitivity cardiac troponin I (hs-cTnI) differed among women who developed PPCM versus unaffected pregnancies. Cases were matched to unaffected women by age, race, parity, and gestational age of sample (control A) and then further by blood pressure and pregnancy weight gain (control B).

This cases series examines SARS-CoV-2 placentitis and intraparenchymal thrombohematomas among COVID-19 infections during pregnancy.

Pregnant Individuals' Views on Fetal Tissue Research in the United States.

Objective: Fetal tissue research has driven significant medical advances but remains publicly contentious in the United States. The views of pregnant individuals in the United States regarding the donation of fetal tissue offer an important and previously unexplored perspective on this issue.

Methods: We conducted a secondary analysis of data from two separate, broader qualitative studies.

Unusual Presentation of Post-coital Spontaneous Coronary Artery Dissection.

Spontaneous coronary artery dissection (SCAD) is a grave medical condition that is defined as a separation of the coronary artery wall layer. This presentation is rare in males and can be triggered by cardio-circulatory stress, such as exercise and emotional stress. Sexual intercourse is considered potent cardiovascular stress that can be strenuous and cause rapid and significant changes in the heart rate and blood pressure which can predispose SCAD.

Leveraging the Massachusetts perinatal quality collaborative to address the COVID-19 pandemic among diverse populations.

Objective: We leveraged the Massachusetts perinatal quality collaborative (PQC) to address the COVID-19 pandemic. Our goals were to: (1) implement perinatal practices thought to reduce mother-to-infant SARS-CoV-2 transmission while limiting disruption of health-promoting practices and (2) do so without inequities attributable to race/ethnicity, language status, and social vulnerability.

Methods: Main outcomes were cesarean and preterm delivery, rooming-in, and breastfeeding.
