RESUMEN
PURPOSE: To investigate the association between dry eye (DE) and insomnia symptom severity. METHODS: Cross-sectional study of 187 individuals seen in the Miami Veterans Affairs eye clinic. An evaluation was performed consisting of questionnaires regarding insomnia (insomnia severity index [ISI]) and DE symptoms, including ocular pain, followed by a comprehensive ocular surface examination. Using a two-step cluster analysis based on intensity ratings of ocular pain, the patient population was divided into two groups (high and low ocular pain groups: HOP and LOP). A control group was ascertained at the same time from the same clinic as defined by no symptoms of DE (Dry Eye Questionnaire 5 [DEQ5], <6). The main outcome measure was the frequency of moderate or greater insomnia in the DE groups. RESULTS: The mean age of the study sample was 63 years, and 93% were male. All insomnia complaints were rated higher in the HOP group compared with the LOP and control groups (P<0.0005). Most (61%) individuals in the HOP group experienced insomnia of at least moderate severity (ISI≥15) compared with the LOP (41%) and control groups (18%) (P<0.0005). Black race (odds ratio [OR], 2.7; 95% confidence interval [CI], 1.2-6.0; P=0.02), depression severity (OR, 1.2; 95% CI, 1.1-1.3; P<0.0005), and DE symptom severity (DEQ5; OR, 1.1; 95% CI, 1.01-1.2; P=0.03) were significantly associated with clinical insomnia (ISI≥15) after controlling for potential confounders. CONCLUSIONS: After adjusting for demographics and medical comorbidities, we show that DE symptom severity is positively associated with insomnia severity.

OBJECTIVES: To assess the utility of genomic testing in risk-stratifying Black patients with low and intermediate risk prostate cancer. METHODS: We retrospectively identified 63 Black men deemed eligible for active surveillance based on National Comprehensive Cancer Network (NCCN) guidelines, who underwent OncotypeDx Genomic Prostate Score testing between April 2016 and July 2020. Nonparametric statistical testing was used to compare relevant features between patients reclassified to a higher NCCN risk after genomic testing and those who were not reclassified. RESULTS: The median age was 66 years and median pre-biopsy PSA was 7.3. Initial risk classifications were: very low risk: 7 (11.1%), low risk: 24(38.1%), favorable intermediate risk: 31(49.2%), and unfavorable intermediate risk: 1 (1.6%). Overall, NCCN risk classifications after Genomic Prostate Score testing were significantly higher than initial classifications (P=.003, Wilcoxon signed-rank). Among patients with discordant risk designations, 28(28/40, 70%) were reclassified to a higher NCCN risk after genomic testing. A pre-biopsy prostate specific antigen of greater than 10 did not have significantly higher odds of HBR (OR:2.16 [95% CI: 0.64,7.59, P=.2). Of favorable intermediate risk patients, 20(64.5%) were reclassified to a higher NCCN risk. Ultimately, 18 patients underwent definitive treatment. CONCLUSIONS: Incorporation of genomic testing in risk stratifying Black men with low and intermediate-risk prostate cancer resulted in overall higher NCCN risk classifications. Our findings suggest a role for increased utilization of genomic testing in refining risk-stratification within this patient population. These tests may better inform treatment decisions on an individualized basis.

The thulium fiber laser (TFL) is a novel technology under active investigation as an conceivable alternative to the Holmium:yttrium-aluminum-garnet (Ho:YAG) laser, which is currently the gold standard for an array of urologic procedures. The purpose of this review is to discuss the existing literature on the functionality and effectiveness of TFL in urological practice. We conducted a search of the PubMed, Medline, Web of Science Core Collection, SCOPUS, Embase (OVID), and Cochrane Databases for all full articles and systematic reviews on the TFL. We found a total of 35 relevant pieces of literature. The early research findings pertaining to the TFL exhibit numerous potential advantages over the Ho:YAG laser. In vitro and ex vivo studies have highlighted the TFL's ability to utilize smaller laser fibers, obtain faster stone ablation rates, and achieve less retropulsion when tested against the Ho:YAG laser in lithotripsy. Currently, there is limited in vivo research that investigates the utilization of the TFL. The in vivo results that are available, however, look promising both for laser lithotripsy and soft tissue ablation. Indeed, the existing literature suggests that the TFL has great potential and may possess numerous technological advantages over the Ho:YAG laser, especially in laser lithotripsy. Although these early studies are promising, randomized control trials are needed to assess the full applicability of the TFL in urology.

Introduction and Objective: Patients presenting with a urinary tract infection with kidney or ureteral stones is a urologic emergency often achieve early clinical stability but remain hospitalized while awaiting results from urine antibiotic sensitivity analyses. We aimed to identify clinical predictors of antibiotic resistance in patients who underwent urgent urinary tract decompression for sepsis and obstructive urolithiasis to facilitate early discharge on empiric oral antibiotics. Methods: Patients who underwent emergent urinary tract decompression for sepsis and an obstructing ureteral stone from 2014 to 2018 at two academic medical institutions were identified. Emergent stent placement was performed and patients were treated with broad-spectrum intravenous antibiotics. We assessed the association between clinical parameters at the time of presentation and resistance to at least one antibiotic from urine culture using the Wilcoxon test and Fisher exact test for continuous and categorical variables, respectively. Multivariate logistic regression was then performed using all significant variables from univariate analysis. Results: Out of 134 patients, 84 patients (62.7%) had urine cultures resistant to at least one antibiotic. On univariate analysis, patients with resistant cultures were significantly more likely to have had previous ureteroscopy, require postoperative intensive care unit-level care, have bacteremia, and a longer length of stay. In multivariate analysis using significant variables from univariate analysis, only previous ureteroscopy was significantly associated with antibiotic resistance with an increased odds of 6.95 (p = 0.011). Conclusions: In this study, we show that a history of ureteroscopy is significantly associated with antibiotic resistance in both univariate and multivariate analyses. Our findings suggest that patients with history of ureteroscopy should await urine culture results, while those without a history of ureteroscopy may be discharged early on empiric oral antibiotics. However, future studies are necessary to determine the effectiveness of this predictor.

IMPORTANCE: Somatosensory dysfunction likely underlies dry eye (DE) symptoms in many individuals yet remains an understudied component of the disease. Its presence has important diagnostic and therapeutic implications. OBJECTIVE: To assess the integrity of nociceptive system processes in persons with DE and ocular pain using quantitative sensory testing (QST) techniques applied at a site remote from the eye. DESIGN, SETTING, AND PARTICIPANTS: A cross-sectional study conducted at Miami Veterans Affairs Hospital included 118 individuals with a wide variety of DE symptoms and signs. The study was conducted from October 31, 2013, to January 28, 2016. INTERVENTIONS: Individuals completed questionnaires regarding ocular symptoms (5-Item Dry Eye Questionnaire [DEQ5], Ocular Surface Disease Index [OSDI], and Neuropathic Pain Symptom Inventory modified for the eye [NPSI-E]), psychological status, and medication use and underwent an ocular surface examination. The QST metrics included measures of vibratory and thermal thresholds and cold and hot pain temporal summation (surrogate measures of central sensitization) on the forearm. MAIN OUTCOMES AND MEASURES: Correlations among DE and ocular pain symptom severity with QST metrics measured on the forearm. The OSDI score ranges from 0 to 100, with 100 indicating the most severe DE symptoms. The DEQ5 score ranges from 0 to 22, with the highest score indicating the most severe symptoms, and the NPSI-E score ranges from 0 to 100, with the highest score indicating the most severe symptoms. Psychological state was measured with the 9-item Patient Health Questionnaire, the PTSD Checklist-Military Version for PTSD, and the Symptom Checklist-90 for anxiety. RESULTS: Of the 118 patients who participated in the study, 105 (88.9%) were men (mean [SD] age, 60 [10] years), and a mean of 41% had PTSD, 10% depression, and 0.93% anxiety. Using stepwise linear regression analyses, significant associations were identified between overall DE symptom severity and posttraumatic stress disorder scores and tear breakup time (DEQ5 model: R = 0.54; OSDI model: R = 0.61, P < .001). All other variables (ie, demographics, comorbidities, medications, tear film factors, and QST metrics) dropped out of these models. When specifically considering neuropathic-like qualities of DE pain, however, anxiety and hot pain temporal summation at the forearm explained 17% of the variability in ocular burning (R = 0.41; P < .001), and PTSD score, tear breakup time, and hot pain temporal summation at the forearm explained 25% of the variability in sensitivity to wind (R = 0.50; P < .001) and 30% of the variability in total NPSI-E scores (R = 0.55; P < .001). CONCLUSIONS AND RELEVANCE: Our findings demonstrate that neuropathic-like DE pain symptom severity correlates with quantitative measures of pain sensitivity at a site remote from the eye. This result provides additional evidence that DE symptoms are not only manifestations of a local disorder but also involve somatosensory dysfunction beyond the trigeminal system.

UNLABELLED: Recent data show that dry eye (DE) susceptibility and other chronic pain syndromes (CPS) such as chronic widespread pain, irritable bowel syndrome, and pelvic pain, might share common heritable factors. Previously, we showed that DE patients described more severe symptoms and tended to report features of neuropathic ocular pain (NOP). We hypothesized that patients with a greater number of CPS would have a different DE phenotype compared with those with fewer CPS. We recruited a cohort of 154 DE patients from the Miami Veterans Affairs Hospital and defined high and low CPS groups using cluster analysis. In addition to worse nonocular pain complaints and higher post-traumatic stress disorder and depression scores (P < .01), we found that the high CPS group reported more severe neuropathic type DE symptoms compared with the low CPS group, including worse ocular pain assessed via 3 different pain scales (P < .05), with similar objective corneal DE signs. To our knowledge, this was the first study to show that DE patients who manifest a greater number of comorbid CPS reported more severe DE symptoms and features of NOP. These findings provided further evidence that NOP might represent a central pain disorder, and that shared mechanistic factors might underlie vulnerability to some forms of DE and other comorbid CPS. PERSPECTIVE: DE patients reported more frequent CPS (high CPS group) and reported worse DE symptoms and ocular and nonocular pain scores. The high CPS group reported symptoms of NOP that share causal genetic factors with comorbid CPS. These results imply that an NOP evaluation and treatment should be considered for DE patients.

PURPOSE: The purpose of this project was to study the relationship between conjunctivochalasis (Cch) and ocular signs and symptoms of dry eye. METHODS: Ninety-six patients with normal eyelid and corneal anatomy were prospectively recruited from a Veterans Administration hospital over 12 months. Symptoms (via the dry eye questionnaire 5 [DEQ5]) and signs of dry eye were assessed along with quality of life implications. Statistical analyses comparing the above metrics among the three groups included χ(2), analysis of variance, and linear regression tests. RESULTS: Participants were classified into three groups: nasal conjunctivochalasis (NCch; n = 31); nonnasal conjunctivochalasis (non-NCch; n = 41); and no conjunctivochalasis (no-Cch; n = 24). Patients with NCch had more dry eye symptoms than those with non-NCch (DEQ5: NCch = 13.8 ± 5.0, non-NCch = 10.2 ± 5.0, no-Cch = 11.6 ± 5.8; P = 0.014), and more ocular pain than those with Non-NCch and no-Cch (numerical rating scale [NRS]: NCch = 4.5 ± 3.0, non-NCch = 2.3 ± 2.8, no-Cch = 3.3 ± 2.6; P = 0.008). They also had worse dry eye signs compared to those with no-Cch measured by Schirmer score with anesthesia (NCch = 14.5 ± 6.9, non-NCch = 16.8 ± 8.2, no-Cch = 19.9 ± 6.4; P = 0.039); meibomian gland dropout (NCch 1.8 ± 0.9, non-NCch = 1.4 ± 1.0, no-Cch = 1.0 ± 1.0; P = 0.020); and eyelid vascularity (NCch = 0.84 ± 0.8, non-NCch = 0.74 ± 0.7, no-Cch = 0.33 ± 0.6; P = 0.019). Moreover, those with NCch more frequently reported that dry eye symptoms moderately to severely impacted their quality of life (NCch = 87%, non-NCch = 51%, no-Cch = 58%; P = 0.005). CONCLUSIONS: The presence of NCch associates with dry eye symptoms, abnormal tear parameters, and impacts quality of life compared with non-NCch and no-Cch. Based on these data, it is important for clinicians to look for Cch in patients with symptoms of dry eye.
