Abstract
BACKGROUND Health Industry and physician collaboration generates innovation. Colorectal Surgeon (CRS) selection to collaborate might not be random. We aim to identify CRS personal and professional characteristics that facilitate collaboration with the Industry. METHOD Cross-sectional study of Industry payments to CRS (2014-2018) using Open Payments Database from Centers for Medicare & Medicaid Services. Multivariable regression compared variables predicting payment amount including gender, years in practice, leadership positions, H-index, Twitter presence and geographic location. RESULTS Surgeons who were male received 3.1 times the amount in Industry payments as compared to females (p = 0.014). Chairs and Division Chiefs received 2.7 times the amount in payments as compared to those without these leadership positions (p = 0.003). Surgeons with an H-index ≥ 8 received 2.2 times the amount in payments as compared to those with H-index < 8 (p = 0.001). Surgeons in practice for 12-19 and 20-30 years received 3 times and 4.4 times the amount in payments as compared to surgeons in practice for 1-11 years (p = 0.036 and p = 0.017, respectively). Surgeons in the South received 3.2 times and 2 times the amount in payments as compared to surgeons in the Northeast (p < 0.0005) and in the Midwest (p = 0.006). Surgeons with Twitter accounts received 1.7 times the amount in payments as compared to surgeons without Twitter (p = 0.036). Among Twitter users, those with 321-17,200 followers received 4.7 times and 9.5 times the amount in payments as compared to those with 0-15 and 16-79 followers, respectively (p = 0.008 and p = 0.009). CONCLUSION Industry payments are more commonly addressed to male, senior surgeons in leadership tracks with strong social media outreach. With the increasing gender and racial variety in the CRS field, it is expected that collaborations between industry and surgeons will become more diverse and inclusive.

[PMID: 31665287 PMCID: PMC6847974 DOI: 10.1093/humupd/dmz032] [Citation(s) in RCA: 58] [Impact Index Per Article: 14.5] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2019] [Revised: 07/14/2019] [Accepted: 08/13/2019] [Indexed: 01/12/2023] Open
Abstract
BACKGROUND Intensive research on sperm ion channels has identified members of several ion channel families in both mouse and human sperm. Gene knock-out studies have unequivocally demonstrated the importance of the calcium and potassium conductances in sperm for fertility. In both species, the calcium current is carried by the highly complex cation channel of sperm (CatSper). In mouse sperm, the potassium current has been conclusively shown to be carried by a channel consisting of the pore forming subunit SLO3 and auxiliary subunit leucine-rich repeat-containing 52 (LRRC52). However, in human sperm it is controversial whether the pore forming subunit of the channel is composed of SLO3 and/or SLO1. Deciphering the role of the proton-specific Hv1 channel is more challenging as it is only expressed in human sperm. However, definitive evidence for a role in, and importance for, human fertility can only be determined through studies using clinical samples. OBJECTIVE AND RATIONALE This review aims to provide insight into the role of sperm ion channels in human fertilization as evidenced from recent studies of sperm from infertile men. We also summarize the key discoveries from mouse ion channel knock-out models and contrast the properties of mouse and human CatSper and potassium currents. We detail the evidence for, and consequences of, defective ion channels in human sperm and discuss hypotheses to explain how defects arise and why affected sperm have impaired fertilization potential. SEARCH METHODS Relevant studies were identified using PubMed and were limited to ion channels that have been characterized in mouse and human sperm. Additional notable examples from other species are included as appropriate. OUTCOMES There are now well-documented fundamental differences between the properties of CatSper and potassium channel currents in mouse and human sperm. However, in both species, sperm lacking either channel cannot fertilize in vivo and CatSper-null sperm also fail to fertilize at IVF. Sperm-lacking potassium currents are capable of fertilizing at IVF, albeit at a much lower rate. However, additional complex and heterogeneous ion channel dysfunction has been reported in sperm from infertile men, the causes of which are unknown. Similarly, the nature of the functional impairment of affected patient sperm remains elusive. There are no reports of studies of Hv1 in human sperm from infertile men. WIDER IMPLICATIONS Recent studies using sperm from infertile men have given new insight and critical evidence supporting the supposition that calcium and potassium conductances are essential for human fertility. However, it should be highlighted that many fundamental questions remain regarding the nature of molecular and functional defects in sperm with dysfunctional ion channels. The development and application of advanced technologies remains a necessity to progress basic and clinical research in this area, with the aim of providing effective screening methodologies to identify and develop treatments for affected men in order to help prevent failed ART cycles. Conversely, development of drugs that block calcium and/or potassium conductances in sperm is a plausible strategy for producing sperm-specific contraceptives.

Abstract
Abstract
Endometriosis is an important gynecological disease, affecting 10% of reproductive age women, and associated with pain, infertility, reduced quality of life, and high health economic cost. Except for ultrasound detection of ovarian endometriotic cysts, the gold standard for diagnosis is laparoscopy, leading to diagnostic delays of 5–10 years. Accurate noninvasive biomarkers are needed, especially for symptomatic women with a normal gynecological ultrasound, to triage them towards medical or surgical treatment and to monitor their treatment outcome. Such biomarkers are not available today, largely because the research focus has been on discovery, not on reproducibility and validation. Academia/industry partnerships can move this field forward by validation of promising markers, consensus on endometriosis phenotypes/controls and desirable accuracy (sensitivity/specificity). Such partnerships should increase the quality and reproducibility of target discovery work and foster global consensus on the use of relevant preclinical/animal models, if they are managed with complete (financial) transparency and with the aim to translate innovation into products benefiting patients. It is essential that mutual objectives are clarified between industry and academia partners including intellectual property policy, critical decision points, funding agreements, milestones and timelines, with a clear strategy for project termination/change of strategy, a restriction on publications till new discoveries have been patented, considering that a minority of novel findings can be translated into new therapeutic targets, diagnostics, or marketed products.
