Respiratory outcomes of neonates born after previable premature rupture of membranes and treated with gentle ventilation.

Objective: We aim to describe neonatal respiratory outcomes following previable preterm premature rupture of membranes(PPROM) when gentle ventilation is utilized. We also report maternal morbidity and mortality.

Study Design: This is a retrospective single-center cohort study of infants delivered between 2016 and 2020 that included infants born at ≥23 weeks without major congenital anomaly after a pregnancy complicated with PPROM before 23 weeks gestation.

Evaluation of learning transfer after a perinatal/neonatal palliative care virtual training course.

Background: The success of a training can be determined by the degree of learning transfer. To address a gap in educational offerings during the pandemic, an interdisciplinary team developed and offered a 3-day virtual course, called Next Level Perinatal Palliative Care Training.

Objective: This study aimed to evaluate the transfer of learning and practice from a virtual training course on perinatal/neonatal palliative care (PNPC) by a range of clinicians.

Improving Postpartum Depression Screening in the NICU: Partnering with Students to Improve Outreach.

Unlabelled: Infants born to mothers with postpartum depression (PPD) are at risk for adverse developmental outcomes. Mothers of premature infants are 40% more likely to develop PPD when compared with the general population. Current published studies on implementing PPD screening in the Neonatal Intensive Care Unit (NICU) do not comply with the American Academy of Pediatrics (AAP) guideline, which recommends multiple screening points in the first year postpartum and includes partner screening.

Tuberous sclerosis complex-1 (TSC1) contributes to selective neuronal vulnerability in Alzheimer's disease.

Aims: Selective neuronal vulnerability of hippocampal Cornu Ammonis (CA)-1 neurons is a pathological hallmark of Alzheimer's disease (AD) with an unknown underlying mechanism. We interrogated the expression of tuberous sclerosis complex-1 (TSC1; hamartin) and mTOR-related proteins in hippocampal CA1 and CA3 subfields.

Methods: A human post-mortem cohort of mild (n = 7) and severe (n = 10) AD and non-neurological controls (n = 9) was used for quantitative and semi-quantitative analyses.

Options in bariatric surgery: modeled decision analysis supports Roux-en-Y gastric bypass and sleeve gastrectomy as the treatments of choice.

Background: Obesity is a chronic disease associated with significant morbidity and mortality. Bariatric surgery has been shown to significantly reduce both morbidity and mortality. Numerous surgical strategies exist, but the most frequently used worldwide are adjustable gastric banding, sleeve gastrectomy (SG), and Roux-en-Y gastric bypass (RYGB).

Intact memory for irrelevant information impairs perception in amnesia.

Memory and perception have long been considered separate cognitive processes, and amnesia resulting from medial temporal lobe (MTL) damage is thought to reflect damage to a dedicated memory system. Recent work has questioned these views, suggesting that amnesia can result from impoverished perceptual representations in the MTL, causing an increased susceptibility to interference. Using a perceptual matching task for which fMRI implicated a specific MTL structure, the perirhinal cortex, we show that amnesics with MTL damage including the perirhinal cortex, but not those with damage limited to the hippocampus, were vulnerable to object-based perceptual interference.

Functional dissociation within the entorhinal cortex for memory retrieval of an association between temporally discontiguous stimuli.

Anatomical connectivity and single neuron coding suggest a segregation of information representation within lateral (LEC) and medial (MEC) portions of the entorhinal cortex, a brain region serving as the primary input/output of the hippocampus and maintaining widespread connections to many association cortices. The present study aimed to expand this idea by examining whether these two subregions differentially contribute to memory retrieval for an association between temporally discontiguous stimuli. We found that reversible inactivation of the LEC, but not the MEC, severely impaired the retrieval of the recently and remotely acquired memory in rat trace eyeblink conditioning, in which a stimulus-free interval was interposed between the conditioned and unconditioned stimulus.

Conventional MRI as a diagnostic and prognostic tool in spinal cord injury: a systemic review of its application to date and an overview on emerging MRI methods.

Introduction: The diagnosis and prognosis of traumatic spinal cord injury has historically relied on clinical examination whereby those presenting with severe injuries were deemed unlikely to recover and those presenting with mild injuries were deemed more likely to recover. With the widespread use of MRI to visualize traumatic injury to the spinal cord, a spectrum of previously unseen characteristics ranging from mild T2-weighted signal intensity to complete spinal cord transection is now available to aid in both the diagnosis and prognosis.

Areas Covered: In this systematic review, the authors outline how clinical examination (using the American Spinal Injury Association standards) and MRI characteristics can be used to classify and characterize acute traumatic cervical spinal cord injury.
