Purpose:
Intracavernosal injections are used to treat erectile dysfunction. Patient compliance with intracavernosal injections is required for success, though factors influencing compliance are unknown. This study aimed to identify factors that influence compliance with intracavernosal injections among men with erectile dysfunction.
Materials and Methods:
A retrospective analysis was conducted using men who were prescribed intracavernosal injections between 2017 and 2022 at an academic medical center in a cosmopolitan area. Custom Python code was used to capture the first and last prescription refill events, and the duration of intracavernosal injection use was calculated. Additional patient-related data, including demographics and comorbidities, were gathered through chart reviews. Cox Proportional Hazards Regression models were used to evaluate the effects of predictor variables on the duration of intracavernosal injection use.
Results:
A total of 4,072 patients were included in the analysis. The study revealed that age significantly predicted discontinuation of intracavernosal injection therapy, showing an elevated hazard ratio of 1.007 for each additional year of age (p<0.001). Men who preferred to speak Spanish as their primary language was a significant predictor of discontinuation of injection therapy, showing a hazard ratio of 1.163 compared to those who preferred English (p=0.004). Men with a history of prostate cancer treatment stayed on treatment for 80 days fewer on average than those without (p=0.002).
Conclusions
Older age, prior history of prostate cancer treatment, and men who preferred to speak Spanish were all identified as factors potentially associated with reduced continuation of intracavernosal injection therapy for erectile dysfunction. Understanding these factors can help healthcare providers in both patient selection and counseling when discussing treatment options for erectile dysfunction.

Penile fracture (PF) is a surgical emergency. Given its rarity, we queried a national cohort over an 11-year period to study the temporal and demographic variations in presentation, evaluation, and management of patients with PF compared with a cohort of control patients. The National Inpatient Sample was queried between the years 2005 and 2016 for patients with a diagnosis of PF. Appendectomy patients were selected as a control cohort, given the non-discriminatory nature of this disease. Clinical and demographic data of the patients were compared with that of controls. Presenting symptoms, rates of surgical repair, and rates of associated surgical procedures were evaluated in the PF cohort. During the study period, 5802 patients were hospitalized for PF. The annual incidence of PF remained unchanged at 1.0-1.8 cases per 100 000 hospitalizations over the study period. Compared with the control cohort, PF patients were more likely to be younger (38.7 years vs 41.2 years, P ≤ 0.001), have lower rates of comorbidities except erectile dysfunction (1.4% vs 0.1%, P ≤ 0.001), and were more likely of Black race (25.4% vs 6.2%, P ≤ 0.001). Notably, PF patients had significantly higher rates of substance abuse (26.4% vs 18.1%, P ≤ 0.001), despite no difference in the diagnosed psychiatric disorders. PF rarely presented with hematuria (3.5%); however, urethral evaluation was performed in 23.1%, most commonly with cystoscopy (19.2%). PF occurs more commonly in a younger, healthier male population, and among minorities. Importantly, rates of substance abuse appear to be higher in the PF cohort compared with those of controls.

Hazardous work zones (i.e., hot, warm, and cold) are typically established by emergency response teams during hazardous materials (HAZMAT) callsbut less consistently for fire responses to segment personnel and response activities in the immediate geographic area around the fire. Despite national guidelines, studies have documented the inconsistent use of respiratory protective equipment by firefighters at the fire scene. In this case-series report, we describe warm zone gas levels using multigas detectors across five independent fire incident responses all occurring in a large South Florida fire department. Multigas detector data collected at each fire response indicate the presence of sustained levels of volatile organic compounds in the “warm zone” of each fire event. These cases suggest that firefighters should not only implement strategies for multigas detector use within the warm zone but also include respiratory protection to provide adequate safety from toxic exposures in the warm zone.

As a dioxygenase, Ten-Eleven Translocation 2 (TET2) catalyzes subsequent steps of 5-methylcytosine (5mC) oxidation. TET2 plays a critical role in the self-renewal, proliferation, and differentiation of hematopoietic stem cells, but its impact on mature hematopoietic cells is not well-characterized. Here we show that Tet2 plays an essential role in osteoclastogenesis. Deletion of Tet2 impairs the differentiation of osteoclast precursor cells (macrophages) and their maturation into bone-resorbing osteoclasts in vitro. Furthermore, Tet2 mice exhibit mild osteopetrosis, accompanied by decreased number of osteoclasts in vivo. Tet2 loss in macrophages results in the altered expression of a set of genes implicated in osteoclast differentiation, such as Cebpa, Mafb, and Nfkbiz. Tet2 deletion also leads to a genome-wide alteration in the level of 5-hydroxymethylcytosine (5hmC) and altered expression of a specific subset of macrophage genes associated with osteoclast differentiation. Furthermore, Tet2 interacts with Runx1 and negatively modulates its transcriptional activity. Our studies demonstrate a novel molecular mechanism controlling osteoclast differentiation and function by Tet2, that is, through interactions with Runx1 and the maintenance of genomic 5hmC. Targeting Tet2 and its pathway could be a potential therapeutic strategy for the prevention and treatment of abnormal bone mass caused by the deregulation of osteoclast activities.

The United States (U.S.) is facing a national opioid epidemic, and medical systems are in need of non-pharmacologic strategies that can be employed to decrease the public's opioid dependence. Acupuncture has emerged as a powerful, evidence-based, safe, cost-effective, and available treatment modality suitable to meeting this need. Acupuncture has been shown to be effective for the management of numerous types of pain conditions, and mechanisms of action for acupuncture have been described and are understandable from biomedical, physiologic perspectives. Further, acupuncture's cost-effectiveness can dramatically decrease health care expenditures, both from the standpoint of treating acute pain and through avoiding addiction to opioids that requires costly care, destroys quality of life, and can lead to fatal overdose. Numerous federal regulatory agencies have advised or mandated that healthcare systems and providers offer non-pharmacologic treatment options for pain. Acupuncture stands out as the most evidence-based, immediately available choice to fulfil these calls. Acupuncture can safely, easily, and cost-effectively be incorporated into hospital settings as diverse as the emergency department, labor and delivery suites, and neonatal intensive care units to treat a variety of commonly seen pain conditions. Acupuncture is already being successfully and meaningfully utilized by the Veterans Administration and various branches of the U.S. Military, in some studies demonstrably decreasing the volume of opioids prescribed when included in care.

Results between different clinical laboratory measurement procedures (CLMP) should be equivalent, within clinically meaningful limits, to enable optimal use of clinical guidelines for disease diagnosis and patient management. When laboratory test results are neither standardized nor harmonized, a different numeric result may be obtained for the same clinical sample. Unfortunately, some guidelines are based on test results from a specific laboratory measurement procedure without consideration of the possibility or likelihood of differences between various procedures. When this happens, aggregation of data from different clinical research investigations and development of appropriate clinical practice guidelines will be flawed. A lack of recognition that results are neither standardized nor harmonized may lead to erroneous clinical, financial, regulatory, or technical decisions. Standardization of CLMPs has been accomplished for several measurands for which primary (pure substance) reference materials exist and/or reference measurement procedures (RMPs) have been developed. However, the harmonization of clinical laboratory procedures for measurands that do not have RMPs has been problematic owing to inadequate definition of the measurand, inadequate analytical specificity for the measurand, inadequate attention to the commutability of reference materials, and lack of a systematic approach for harmonization. To address these problems, an infrastructure must be developed to enable a systematic approach for identification and prioritization of measurands to be harmonized on the basis of clinical importance and technical feasibility, and for management of the technical implementation of a harmonization process for a specific measurand.
