OBJECTIVE: To evaluate if shoulder and pelvic angular velocities differ at impact or peak magnitude between professional and amateur golfers. Golf swing rotational biomechanics are a key determinant of power generation, driving distance, and injury prevention. We hypothesize that shoulder and pelvic angular velocities would be highly consistent in professionals. METHODS: Rotational velocities of the upper-torso and pelvis throughout the golf swing and in relation to phases of the golf swing were examined in 11 professionals and compared to 5 amateurs using three-dimensional motion analysis. RESULTS: Peak rotational velocities of professionals were highly consistent, demonstrating low variability (coefficient of variation [COV]), particularly upper-torso rotational velocity (COV=0.086) and pelvic rotational velocity (COV=0.079) during down swing. Peak upper-torso rotational velocity and peak X-prime, the relative rotational velocity of uppertorso versus pelvis, occurred after impact in follow-through, were reduced in amateurs compared to professionals (p=0.005 and p=0.005, respectively) and differentiated professionals from most (4/5) amateurs. In contrast, peak pelvic rotational velocity occurred in down swing. Pelvic velocity at impact was reduced in amateurs compared to professionals (p=0.019) and differentiated professionals from most (4/5) amateurs. CONCLUSION: Golf swing rotational velocity of professionals was consistent in pattern and magnitude, offering benchmarks for amateurs. Understanding golf swing rotational biomechanics can guide swing modifications to help optimize performance and prevent injury.

Objective: To develop a stepwise approach to robotic assisted excision of cesarean scar pregnancy (CSP) with metroplasty. Methods: This illustrative video presentation demonstrating CSP, the criteria for ultrasound diagnosis, and a step-by-step approach for robotic assisted excision of CSP and multi-layer hysterotomy closure at a tertiary medical center. Results: Robotic assisted resection is a safe and feasible method to treat cesarean scar ectopic pregnancies. Key ultrasonographic characteristics of CSP are highlighted to facilitate its diagnosis, thus allowing for early intervention with a minimally invasive surgical treatment as necessary. Our patient was a 30-year-old gravida 2 para 1 woman with a history of 1 prior-term low transverse cesarean delivery, who presented with vaginal bleeding in the first trimester and was ultimately diagnosed with CSP. After unsuccessful methotrexate therapy, the patient underwent an uncomplicated robotic assisted excision of her CSP and metroplasty in 2 layers using a stepwise approach: Step 1-Creation of a bladder flap; Step 2-Isolation and excision of CSP; Step 3-Hysterotomy closure in 2 layers; and Step 4-Hysteroscopy. Conclusion When diagnosed late, cesarean scar ectopic pregnancy can cause a significant hemorrhage from rupture. Early radiologic diagnosis does not only indicate minimally invasive surgery as a treatment option but also assists with related surgical planning. This video demonstrates a stepwise approach to the robotic assisted excision of CSP with metroplasty. With these 4 simple steps, surgical procedure can be safe and efficient.

Environmental and occupational health are interconnected disciplines of public health that are concerned in maintaining a symbiotic relationship between the ecosystem and humans. This relationship is under threat by the continuous and alarming increase of the Earth's temperature causing climate change that impacts not just health but also the economy and the safety of the population. The First National Environmental and Occupational Health Forum was organized by the Department of Environmental and Occupational Health, College of Public Health, University of the Philippines Manila to address and discuss the complex issues that the Philippines is currently experiencing when it comes to environmental and occupational health by providing a space where stakeholders from different sectors can actively participate in mapping out challenges and opportunities. The organizer's long-term vision is to catalyze and build a network of collaboration that is geared towards the improvement of health and safety in the workplace that involves mitigating the effects of climate change. The discussions in the forum gave a comprehensive insight into the different challenges we face for being one of the most vulnerable countries to natural disasters: how this affects health, workplace, and environment. These challenges created new opportunities for the country to build resilience and formulate adaptive strategies to decrease the vulnerability of the population especially the workforce who are constantly exposed to different hazards that are exacerbated by changes in the environment.

Pain is often debilitating, and current treatments are neither universally efficacious nor without risks. Transient receptor potential (TRP) ion channels offer alternative targets for pain relief, but little is known about the regulation or identities of endogenous TRP ligands that affect inflammation and pain. Here, transcriptomic and targeted lipidomic analysis of damaged tissue from the mouse spinal nerve ligation (SNL)-induced chronic pain model revealed a time-dependent increase in Cyp1b1 mRNA and a concurrent accumulation of 8,9-epoxyeicosatrienoic acid (EET) and 19,20-EpDPA post injury. Production of 8,9-EET and 19,20-EpDPA by human/mouse CYP1B1 was confirmed in vitro, and 8,9-EET and 19,20-EpDPA selectively and dose-dependently sensitized and activated TRPA1 in overexpressing HEK-293 cells and Trpa1-expressing/AITC-responsive cultured mouse peptidergic dorsal root ganglia (DRG) neurons. TRPA1 activation by 8,9-EET and 19,20-EpDPA was attenuated by the antagonist A967079, and mouse TRPA1 was more responsive to 8,9-EET and 19,20-EpDPA than human TRPA1. This latter effect mapped to residues Y933, G939, and S921 of TRPA1. Intra-plantar injection of 19,20-EpDPA induced acute mechanical, but not thermal hypersensitivity in mice, which was also blocked by A967079. Similarly, Cyp1b1-knockout mice displayed a reduced chronic pain phenotype following SNL injury. These data suggest that manipulation of the CYP1B1-oxylipin-TRPA1 axis might have therapeutic benefit.
