Individuals with hereditary pancreatic cancer risk include high risk individuals (HRIs) with germline genetic susceptibility to pancreatic cancer (PC) and/or a strong family history of PC. Previously, studies have shown that PC surveillance in HRIs can downstage PC diagnosis and extend survival leading to pancreatic surveillance being recommended for certain HRIs. However, the optimal surveillance strategy remains uncertain, including which modalities should be used for surveillance, how frequently should surveillance be performed, and which sub-groups of HRIs should undergo surveillance.

Background: Emergency general surgery (EGS) involves care of a patient's often previously unknown disease in the setting of an unplanned interaction with the healthcare system. This leads to challenges collecting and interpreting patient reported outcome measures (PROMs).

Methods: We performed a qualitative and mixed methods study using semi-structured interviews during the index hospitalization and at 6-12 months to capture peri-operative patient experiences.

Studies of the genetic heritability of schizophrenia and bipolar disorder examining single nucleotide polymorphisms (SNPs) and copy number variations have failed to explain a large portion of the genetic liability, resulting in substantial missing heritability. Long interspersed element 1 (L1) retrotransposons are a type of inherited polymorphic variant that may be associated with risk for schizophrenia and bipolar disorder. We performed REBELseq, a genome wide assay for L1 sequences, on DNA from male and female persons with schizophrenia and controls ( = 63 each) to identify inherited L1 insertions and validated priority insertions.

Objective: To inform clinicians' equipment recommendations by characterizing the experiences, skin integrity, and interface pressures in a series of recently discharged individuals with spinal cord injury (SCI) who chose to use an alternative adjustable bed system at home rather than a standard of care hospital bed with mattress overlay.

Design: Mixed methods, observational case series.

Setting: Community based.

Objective: To determine if long interspersed element-1 (L1) retrotransposons convey risk for idiopathic temporal lobe epilepsy (TLE).

Methods: Surgically resected temporal cortex from individuals with TLE (N = 33) and postmortem temporal cortex from individuals with no known neurological disease (N = 33) were analyzed for L1 content by Restriction Enzyme Based Enriched L1Hs sequencing (REBELseq). Expression of three KCNIP4 splice variants was assessed by droplet digital PCR (ddPCR).

Long interspersed element-1 retrotransposons (LINE-1 or L1) are ∼6 kb mobile DNA elements implicated in the origins of many Mendelian and complex diseases. The actively retrotransposing L1s are mostly limited to the L1 human specific (L1Hs) transcriptional active (Ta) subfamily. In this manuscript, we present REBELseq as a method for the construction of Ta subfamily L1Hs-enriched next-generation sequencing libraries and bioinformatic identification.
