Development of a new Peyronie's disease self-assessment screening app.

Peyronie's disease (PD) is an underdiagnosed and undertreated fibroproliferative disorder associated with the formation of plaques that results in penile curvature and discourages some men from seeking medical consultation. The PD self-assessment app, a digital application (app), was developed to increase PD awareness, provide men with a self-screening and educational tool for PD, and help eliminate barriers to seeking consultation with a physician. Prior to deployment, 4 board-certified urologists provided qualitative reviews on the app's usability and utility as a screening tool.

A Computational Protocol for the Knowledge-Based Assessment and Capture of Pathologies.

We propose that one of the main hurdles in delivering comprehensively informed care results from the challenges surrounding the extraction, representation, and retention of prior clinical experience and basic medical knowledge, as well as its translation into time- and context-informed actionable interventions. While emerging applications in artificial intelligence-based techniques, for example, large language models, offer impressive pattern association capabilities, they often fall short in producing human-readable explanations crucial to their integration into clinical care. Moreover, they require large well-defined and well-integrated data sets that typically conflict with the availability of such data in all but a few areas of medicine, for example, medical imaging and neuroimaging, noninvasive monitoring of bio-electrical activity, etc.

A Computational Pipeline for Identifying Gene Regulatory Networks: A Case Study of Response to Exercise.

Gene regulatory networks are foundational in the control of virtually all biological processes. These networks orchestrate a myriad of cell functions ranging from metabolic rate to the response to a drug or other intervention. The data required to accurately identify these control networks remains very cost and labor intensive typically leading to relatively sparse time course data that is largely incompatible with conventional data-driven model identification techniques.

Sex-Specific Skeletal Muscle Gene Expression Responses to Exercise Reveal Novel Direct Mediators of Insulin Sensitivity Change.

Background: Understanding the causal pathways, systems, and mechanisms through which exercise impacts human health is complex. This study explores molecular signaling related to whole-body insulin sensitivity (Si) by examining changes in skeletal muscle gene expression. The analysis considers differences by biological sex, exercise amount, and exercise intensity to identify potential molecular targets for developing pharmacologic agents that replicate the health benefits of exercise.

HPV Self-Sampling for Cervical Cancer Screening in Under-Screened Saskatchewan Populations: A Pilot Study.

Of all cancers in female Canadians, the most rapidly increasing incidence is that of cervical cancer. The objective of this pilot study was to assess how HPV self-sampling might improve cervical cancer screening participation in both urban and rural settings in Saskatchewan, one of the most sparsely populated provinces in Canada. Study groups consisted of = 250 participants to whom self-swabbing kits were mailed with instructions and = 250 participants to whom kits were handed out in 6 urban and rural clinics.

Imaging techniques for diagnosing and managing Peyronie disease.

Erectile dysfunction (ED) affects up to 50% of men to some degree and has a variety of physiologic and psychologic causes, but many patients do not seek specialist treatment. One cause of ED is Peyronie disease (PD) defined by the presence of fibrotic plaques in the tunica albuginea which cause painful penile contractures. While diagnosing PD relies on clinical history and a focused history and physical exam, adding imaging studies can identify nonpalpable plaques and any underlying vasculogenic ED to tailor the extent of surgical treatment and determine when implantable penile prostheses are beneficial.

Sexual Medicine Society of North America (SMSNA)/American Urological Association (AUA) telemedicine and men's health white paper.

Purpose: The purpose of this white paper is to educate health care professionals about the evolution of telemedicine (TM) and to propose a hybrid model that leverages the strengths of traditional in-person medicine as well as virtual medicine while maximizing the safety and quality of men's sexual health care.

Literature Search Strategy: A literature search focused on the use of TM in urology and men's health was performed through PubMed/MEDLINE, Embase, and Web of Science (January 1, 2012-April 26, 2022). Keywords included all known permutations of the terminology used to refer to virtual health, care as well as the terminology used to refer to urologic diseases, issues specific to men's health, and men's sexual health concerns.

A regulatory pathway model of neuropsychological disruption in Havana syndrome.

Introduction: In 2016 diplomatic personnel serving in Havana, Cuba, began reporting audible sensory phenomena paired with onset of complex and persistent neurological symptoms consistent with brain injury. The etiology of these Anomalous Health Incidents (AHI) and subsequent symptoms remains unknown. This report investigates putative exposure-symptom pathology by assembling a network model of published bio-behavioral pathways and assessing how dysregulation of such pathways might explain loss of function in these subjects using data available in the published literature.

Effects of Amount and Profile of Amino Acids Supply on Lactation Performance, Mammary Gland Metabolism, and Nitrogen Efficiency in Holstein Dairy Cows.

To evaluate the effects of amount and profile of amino acid (AA) on milk protein yield (MPY), mammary metabolism, and efficiency of nitrogen use (ENU), ten cows were used in 5 × 5 replicated Latin squares and fed a positive control (16.1% crude protein-CP) or two lower CP diets (14.6 and 13.

Conversion to Disposable Cystoscopes Decreased Post-procedure Encounters and Infections Compared to Reusable Cystoscopes.

Introduction: We evaluated for differences in post-procedure 30-day encounters or infections following office cystoscopy using disposable vs reusable cystoscopes.

Methods: Cystoscopies performed from June to September 2020 and from February to May 2021 in our outpatient practice were retrospectively reviewed. The 2020 cystoscopies were performed with reusable cystoscopes, and the 2021 cystoscopies were performed with disposable cystoscopes.

Priapism or Prolonged Erection: Is 4 - 6 Hours of Cavernous Ischemia the Time Point of Irreversible Tissue Injury?

Introduction: Ischemic priapism remains a significant cause of morbidity among men. To date, the precise time when penile ischemia results in permanent, non-reversible cavernosal smooth muscle injury, compromising subsequent erectile integrity, remains ill-defined.

Objectives: To review the medical literature pertaining to ischemic priapism, focusing on factors that predict the exact timeline of irreversible cavernous tissue injury.

Understanding the Urology Program Directors Perspective on the Current Resident Selection Process: The Society of Academic Urologists National Survey of Urology Program Directors.

Objective: The traditional residency selection process was altered dramatically by the SARS CoV-2 (COVID-19) pandemic. For the 2020-2021 application cycle in-person interviews were transitioned to the virtual format. What was thought to be a temporary transition has now become the new standard with continued endorsement from the Association of American Medical Colleges (AAMC) and the Society of Academic Urologists (SAU) for virtual interviews (VI).

The Impact of the Virtual Interview on Candidate Experience and Outcomes: Society of Academic Urologists National Survey of Interns Who Participated in the 2020-2021 Urology Match.

Objective: To examine retrospective experiences with the virtual interview (VI) process among postgraduate year 1 (PGY1) urology residents who participated in the 2020-2021 American Urologic Association (AUA) Match cycle.

Methods: A 27-question survey created by a Society of Academic Urologists Taskforce on VI was distributed to PGY1 residents from 105 institutions between February 1, 2022 and March 7, 2022. The survey asked respondents to reflect on the VI process, cost concerns, and how experiences at their current program aligned with prior VI representation.

A rare case of BK virus non-hemorrhagic cystitis following lung transplant.

BK virus cystitis is known to occur following hematopoietic stem cell transplant (HSCT), but few cases exist in the literature following lung transplant. Because of the rarity of this presentation, patients may have missed diagnoses and prescribed ineffective treatments. We present our case of an atypical presentation of BK virus cystitis appearing as bladder carcinoma in situ in a lung transplant patient.

Old drugs, new tricks: leveraging known compounds to disrupt coronavirus-induced cytokine storm.

A major complication in COVID-19 infection consists in the onset of acute respiratory distress fueled by a dysregulation of the host immune network that leads to a run-away cytokine storm. Here, we present an in silico approach that captures the host immune system's complex regulatory dynamics, allowing us to identify and rank candidate drugs and drug pairs that engage with minimal subsets of immune mediators such that their downstream interactions effectively disrupt the signaling cascades driving cytokine storm. Drug-target regulatory interactions are extracted from peer-reviewed literature using automated text-mining for over 5000 compounds associated with COVID-induced cytokine storm and elements of the underlying biology.

Mapping the network biology of metabolic response to stress in posttraumatic stress disorder and obesity.

The co-occurrence of stress-induced posttraumatic stress disorder (PTSD) and obesity is common, particularly among military personnel but the link between these conditions is unclear. Individuals with comorbid PTSD and obesity manifest other physical and psychological problems, which significantly diminish their quality of life. Current understanding of the pathways connecting stress to PTSD and obesity is focused largely on behavioral mediators alone with little consideration of the biological regulatory mechanisms that underlie their co-occurrence.

Network Modeling of Complex Time-Dependent Changes in Patient Adherence to Adjuvant Endocrine Treatment in ER+ Breast Cancer.

Early patient discontinuation from adjuvant endocrine treatment (ET) is multifactorial and complex: Patients must adapt to various challenges and make the best decisions they can within changing contexts over time. Predictive models are needed that can account for the changing influence of multiple factors over time as well as decisional uncertainty due to incomplete data. AtlasTi8 analyses of longitudinal interview data from 82 estrogen receptor-positive (ER+) breast cancer patients generated a model conceptualizing patient-, patient-provider relationship, and treatment-related influences on early discontinuation.

Proteomic Network Analysis of Bronchoalveolar Lavage Fluid in Ex-Smokers to Discover Implicated Protein Targets and Novel Drug Treatments for Chronic Obstructive Pulmonary Disease.

Bronchoalveolar lavage of the epithelial lining fluid (BALF) can sample the profound changes in the airway lumen milieu prevalent in chronic obstructive pulmonary disease (COPD). We compared the BALF proteome of ex-smokers with moderate COPD who are not in exacerbation status to non-smoking healthy control subjects and applied proteome-scale translational bioinformatics approaches to identify potential therapeutic protein targets and drugs that modulate these proteins for the treatment of COPD. Proteomic profiles of BALF were obtained from (1) never-smoker control subjects with normal lung function (n = 10) or (2) individuals with stable moderate (GOLD stage 2, FEV1 50−80% predicted, FEV1/FVC < 0.

The Diagnosis and Management of Recurrent Ischemic Priapism, Priapism in Sickle Cell Patients, and Non-Ischemic Priapism: An AUA/SMSNA Guideline.

Purpose: Priapism is a persistent penile erection that continues hours beyond, or is unrelated to, sexual stimulation and results in a prolonged and uncontrolled erection. Given its time-dependent and progressive nature, priapism is a situation that both urologists and emergency medicine practitioners must be familiar with and comfortable managing.

Methodology: A comprehensive search of the literature on acute ischemic priapism and non-ischemic priapism (NIP) was performed by Emergency Care Research Institute for articles published between January 1, 1960 and May 1, 2020.

Complete pathologic response of bulbar urethral squamous cell carcinoma in situ to topical 5-fluorouracil with urethral milking.
