Purpose: This study evaluated a new subretinal method for delivery of human or pig umbilical tissue-derived cells (hUTC or pUTC, respectively) using a novel subretinal injection cannula and suprachoroidal approach in Göttingen minipig eyes. hUTC (palucorcel) are currently under development for treating geographic atrophy in humans. Methods: Twenty-four Göttingen minipigs (divided into eight groups) were subretinally administered palucorcel, pUTC, or vehicle. In some cases, fluorescently labeled cells and vehicle were administered...

BACKGROUND: Patient and public involvement is required where changes to care provided by the UK National Health Service are proposed. Yet involvement is characterized by ambiguity about its rationales, methods and impact. AIMS: To understand how patients and carers were involved in major system changes (MSCs) to the delivery of acute stroke care in 2 English cities, and what kinds of effects involvement was thought to produce. METHODS: Analysis of documents from both MSC projects, and retrospective in-depth interviews with 45 purposively selected individuals (providers, commissioners, third-sector employees) involved in the MSC...

With every deep inspiration (DI) or sigh the airway wall stretches, as do the airway smooth muscle cells that it contains. In response, the airway smooth muscle (ASM) cell undergoes rapid stretch-induced cytoskeletal fluidization. As a molecular mechanism underlying that ASM fluidization response, here we demonstrate a key role for the actin-severing protein, cofilin. Using primary human ASM cells, we simulated a DI by imposing a transient stretch of physiologic magnitude and duration. We measured the resulting changes in contractile forces using traction microscopy...

Arjan Flora, Daniel Pipoly
A 52-year-old man developed interstitial pneumonitis during treatment with desvenlafaxine for major depressive disorder. The man received desvenlafaxine at 50 mg for symptoms of depression 4 years earlier. Six months after a dose increase to 100 mg, he developed bronchitic symptoms with mild, persistent dyspnea. Investigations revealed a restrictive pattern on pulmonary function testing, bilateral upper lobe reticular opacities with traction bronchiectasis on radiology imaging, and end-stage interstitial fibrosis with honeycomb changes consistent with chronic hypersensitivity pneumonitis on open lung biopsy...

Brett Fleisher, Sihem Ait-Oudhia
Background: Biologics have gained traction for use in oncology, but have demonstrate clinical variability for efficacy and safety. Therapeutic drug monitoring (TDM) can benefit patients' outcomes from a biologic therapy when the latter has a defined therapeutic window. A clinically relevant therapeutic window may exist for biologics with established exposure-response (E-R) relationships for efficacy and/or safety and a documented maximum tolerated dose (MTD). Additionally, the inter-individual variability (IIV) on the clearance (CL) parameter could determine risks for patients falling outside the proposed therapeutic window...

Medical education is currently undergoing a paradigm shift from process-based to competency-based education, focused on measuring the desired competence of a physician. In an attempt to improve the assessment framework used for medical education, the concept of entrustable professional activities (EPAs) has gained traction. EPAs are defined as professional activities that can be entrusted to an individual in a clinical context. The Association of American Medical Colleges (AAMC) defined a set of 13 such EPAs to define the core of what all students should be able to do on day 1 of residency, regardless of specialty choice...

A rare case of a 15-year-old male patient with neuromuscular scoliosis with forced vital capacity (FVC) below 30%, who went through a successful surgery without any pulmonary complications, is reported herein. The patient had obvious asymmetric shoulders and poor exercise tolerance. The Cobb's angle of the main thoracic curve was 62.8°, and FVC in sitting position was 18% of predictive value. After skull traction and pulmonary rehabilitation, the FVC was still below 30%, and he finally went through surgery under this serious condition...

"Financial toxicity" has now become a familiar term used in the discussion of cancer drugs, and it is gaining traction in the literature given the high price of newer classes of therapies. However, as a phenomenon in the contemporary treatment and care of people with cancer, financial toxicity is not fully understood, with the discussion on mitigation mainly geared toward interventions at the health system level. Although important, health policy prescriptions take time before their intended results manifest, if they are implemented at all...

Jordan R Stern, Danielle E Cafasso, Darren B Schneider, Andrew J Meltzer
Here, we describe a totally percutaneous technique for longitudinal fenestration of a chronic dissection flap in the setting of endovascular aneurysm repair (EVAR), where the septum would otherwise preclude proper endograft sealing. This technique is demonstrated in a 65-year-old man with a history of open surgical repair of a Stanford type A aortic dissection, with a type B component that was managed nonoperatively. The patient developed aneurysmal degeneration of the infrarenal aorta during follow-up, and his anatomy was well suited for EVAR with the exception of a chronic dissection flap dividing the proximal seal zone...

The impression that cheek filling results in longitudinal shortening ("lift") of the skin and elevation of the nasolabial crease(NLC) or nasolabial fold (NLF) has become common within the facial injection community, but remains unsubstantiated. In this study, seventy-seven patients were evaluated pre and post-injection injection of the cheeks with an Hyaluronic Acid filler using a 3-dimensional camera system. A constant pattern of skin expansion away from the center of the injection and perpendicular to the surface of the skin was observed...

Niamh Reilly
The recent unprecedented focus on ending impunity for conflict-related sexual violence (CRSV) is positive in many respects. However, it has narrowed the scope of Security Council Resolution 1325 and the women, peace, and security (WPS) agenda it established in 2000. Through a critical discursive genealogy of the interrelation of two UN agendas-protection of civilians in armed conflict and women, peace, and security-the author traces how CRSV emerged as the defining issue of the latter while the transformative imperative of making women's participation central to every UN endeavor for peace and security has failed to gain traction...

The concept of precision medicine, also referred to as individualized or personalized medicine, has recently gained traction in scientific, medical, and public spheres, and is frequently mentioned as the next model of healthcare delivery. Its goal is to integrate unique information obtained from a given patient to customize the care provided to achieve the best possible outcome. Although precision medicine is not fully implemented yet, its application is slowly infiltrating clinical practice, and the dream of individualizing healthcare to each patient is now closer to being fulfilled...

Truncating mutations in the sarcomere protein titin cause dilated cardiomyopathy due to sarcomere insufficiency. However, it remains mechanistically unclear how these mutations decrease sarcomere content in cardiomyocytes. Utilizing human induced pluripotent stem cell-derived cardiomyocytes, CRISPR/Cas9, and live microscopy, we characterize the fundamental mechanisms of human cardiac sarcomere formation. We observe that sarcomerogenesis initiates at protocostameres, sites of cell-extracellular matrix adhesion, where nucleation and centripetal assembly of α-actinin-2-containing fibers provide a template for the fusion of Z-disk precursors, Z bodies, and subsequent striation...

BACKGROUND: We conducted a two-phase randomized controlled trial of a Learning Collaborative (LC) to facilitate implementation of treat to target (TTT) to manage rheumatoid arthritis (RA). We found substantial improvement in implementation of TTT in Phase I. Herein, we report on a second 9 months (Phase II) where we examined maintenance of response in Phase I and predictors of greater improvement in TTT adherence. METHODS: We recruited 11 rheumatology sites and randomized them to either receive the LC during Phase I or to a wait-list control group that received the LC intervention during Phase II...
