Emerging pharmacological strategies for treating and preventing mpox.

Introduction: Since May 2022, there have been nearly 87,000 documented cases of mpox worldwide, with 119 deaths. Pharmacological interventions for mpox include the MVA-BN smallpox vaccine, tecovirimat, cidofovir, its pro-drug brincidofovir, and vaccinia immune globulin intravenous (VIGIV).

Areas Covered: The literature search and information gathering for this review included the PubMed database focusing on mpox and monkeypox, in combination with tecovirimat, brincidofovir, cidofovir, VIGIV, and smallpox vaccine.

Posterior urethral morphology on initial voiding cystourethrogram correlates to early renal outcomes in infants with posterior urethral valves.

Introduction: Posterior urethral valves (PUV) is a leading cause of chronic renal failure in childhood. Bladder and posterior urethral deformity in infants with PUV are highly variable on initial voiding cystourethrogram (VCUG). Some types of deformity may be more important than others in determining the severity of the condition.

Predicting childhood chronic kidney disease severity in infants with posterior urethral valve: a critical analysis of creatinine values in the first year of life.

Background: Posterior urethral valve (PUV) is a leading cause of chronic kidney failure in children. Studies have shown that a creatinine nadir above historical cutoff values of 0.8 or 1.

Did COVID-19 Affect Time to Presentation in the Setting of Pediatric Testicular Torsion?

Objectives: To determine if boys with acute testicular torsion, a surgical emergency requiring prompt diagnosis and treatment to optimize salvage of the testicle, delayed presentation to a medical facility and experienced an extended duration of symptoms (DoS), and secondarily, a higher rate of orchiectomy, during the coronavirus disease 2019 (COVID-19) pandemic.

Methods: Single-center, descriptive retrospective chart review of boys presenting with acute testicular torsion from March 15, to May 4, 2020 ("during COVID-19" or group 2), as well as for the same time window in the 5-year period from 2015 to 2019 ("pre-COVID-19" or group 1).

Results: A total of 78 boys met inclusion criteria, group 1 (n = 57) and group 2 (n = 21).

High incidence of abnormal imaging findings in circumcised boys diagnosed with urinary tract infections.

Background: The American Academy of Pediatrics guidelines recommend delaying voiding cystourethrogram (VCUG) until the second febrile urinary tract infection (UTI). Similarly, the NICE Guidelines do not recommend VCUG after the first febrile UTI in infants and children under three years of age. Currently, there is no good clinical indicator to determine which patients would benefit from an earlier cystogram.

Airway Sensory Nerve Density Is Increased in Chronic Cough.

Chronic cough is characterized by frequent urges to cough and a heightened sensitivity to inhaled irritants. Airway sensory nerves trigger cough. We hypothesized that sensory nerve density is increased in chronic cough, which may contribute to excessive and persistent coughing.

Opioid utilization is minimal after outpatient pediatric urologic surgery.

Introduction: There are no guidelines for opioid use after pediatric urologic surgery, and it is unknown to what extent prescriptions written for these patients may be contributing to the opioid epidemic in the United States. We sought to characterize opioid utilization in a prospective fashion following outpatient pediatric urologic surgery at our institution.

Materials And Methods: After obtainingapproval from the Institutional Review Board, we prospectively recruited pediatric patients undergoing outpatient urologic surgery.

Optimization of patient-specific inhaler regimens with the use of the aerosol inhalation monitor.

Objectives: To describe the addition of a Vitalograph Aerosol Inhalation Monitor (AIM) assessment to a pharmacy bundle to optimize inhaler devices in patients with asthma and chronic obstructive pulmonary disease (COPD).

Setting: Hospital-based outpatient pulmonary clinic.

Practice Description: Ambulatory pharmacy service for underserved pulmonary patients in Detroit, MI.

Eosinophils increase airway sensory nerve density in mice and in human asthma.

In asthma, airway nerve dysfunction leads to excessive bronchoconstriction and cough. It is well established that eosinophils alter nerve function and that airway eosinophilia is present in 50 to 60% of asthmatics. However, the effects of eosinophils on airway nerve structure have not been established.

Eosinophil and airway nerve interactions in asthma.

Airway eosinophils are increased in asthma and are especially abundant around airway nerves. Nerves control bronchoconstiction and in asthma, airway hyperreactivity (where airways contract excessively to inhaled stimuli) develops when eosinophils alter both parasympathetic and sensory nerve function. Eosinophils release major basic protein, which is an antagonist of inhibitory M muscarinic receptors on parasympathetic nerves.

Early Detection of Ureteropelvic Junction Obstruction Using Signal Analysis and Machine Learning: A Dynamic Solution to a Dynamic Problem.

Purpose: We sought to define features that describe the dynamic information in diuresis renograms for the early detection of clinically significant hydronephrosis caused by ureteropelvic junction obstruction.

Materials And Methods: We studied the diuresis renogram of 55 patients with a mean ± SD age of 75 ± 66 days who had congenital hydronephrosis at initial presentation. Five patients had bilaterally affected kidneys for a total of 60 diuresis renograms.

Anticoagulation of Percutaneous Ventricular Assist Device Using Argatroban-Based Purge Solution: A Case Series.

Impella devices are percutaneously inserted ventricular assist devices which require a continuous purge solution that contains heparin to prevent pump thrombosis and device failure. We describe 2 patients with heparin-induced thrombocytopenia (HIT) supported with an Impella device utilizing an argatroban-based purge solution. Case 1 involved an 83-year-old female with biventricular failure which resulted in right ventricle Impella support.

Robotically assisted ureteroscopy for kidney exploration.

Ureteroscopy is a minimally invasive procedure for diagnosis and treatment of a wide range of urinary tract pathologies. It is most commonly performed in the diagnostic work-up of hematuria and the diagnosis and treatment of upper urinary tract malignancies and calculi. Ergonomic and visualization challenges as well as radiation exposure are limitations to conventional ureteroscopy.

Prediction of Clinical Outcomes in Prenatal Hydronephrosis: Importance of Gravity Assisted Drainage.

Purpose: In infants with SFU (Society for Fetal Urology) grade 3-4 congenital hydronephrosis, Tc-mercaptoacetyltriglycine diuretic renography assesses differential function and drainage half-time. We routinely also include the percent of radiotracer drained after 30 minutes of diuresis as well as after 15 minutes with the patient in the upright position. We investigated whether any 1 or more of these parameters on initial diuretic renography predicts persistent or worsening drainage parameters.

Tissue optical clearing, three-dimensional imaging, and computer morphometry in whole mouse lungs and human airways.

In whole adult mouse lung, full identification of airway nerves (or other cellular/subcellular objects) has not been possible due to patchy distribution and micron-scale size. Here we describe a method using tissue clearing to acquire the first complete image of three-dimensional (3D) innervation in the lung. We then created a method to pair analysis of nerve (or any other colabeled epitope) images with identification of 3D tissue compartments and airway morphometry by using fluorescent casting and morphometry software (which we designed and are making available as open-source).

Understanding clinic options for overactive bladder.

Overactive bladder (OAB) is a symptom complex of urinary frequency, nocturia and urgency with or without urgency incontinence that adversely impacts patient's quality of life. Conservative management begins in the outpatient clinic, often with significant improvement and patient satisfaction. In this review we will discuss the evaluation of OAB and review treatment options focusing on behavioral modification, medical therapy, and neuromodulation.

Hypomethylation of the IL17RC promoter associates with age-related macular degeneration.

Age-related macular degeneration (AMD) is the leading cause of irreversible blindness in the elderly population worldwide. Although recent studies have demonstrated strong genetic associations between AMD and SNPs in a number of genes, other modes of regulation are also likely to play a role in the etiology of this disease. We identified a significantly decreased level of methylation on the IL17RC promoter in AMD patients.

Cardiovascular risk factors in hematopoietic cell transplantation survivors: role in development of subsequent cardiovascular disease.

Hematopoietic cell transplantation (HCT) recipients may be at an increased risk of developing hypertension, diabetes, and dyslipidemia (referred to as cardiovascular risk factors [CVRFs]); and these factors can potentially increase the risk of cardiovascular disease (CVD). We examined the incidence and predictors of CVRFs and subsequent CVD in 1885 consecutive 1+year survivors of HCT performed at City of Hope between 1995 and 2004. Ten-year cumulative incidence of hypertension, diabetes, dyslipidemia, and multiple (≥ 2) CVRFs was 37.

Protein arginine methylation in Candida albicans: role in nuclear transport.

Protein arginine methylation plays a key role in numerous eukaryotic processes, such as protein transport and signal transduction. In Candida albicans, two candidate protein arginine methyltransferases (PRMTs) have been identified from the genome sequencing project. Based on sequence comparison, C.
