Personal genital satisfaction is associated with differences in perception of male and female sexual anatomy and function.

BACKGROUND: Prior studies primarily of men correlated low personal genital satisfaction (PGS) with decreased sexual activity; however, the association between PGS and genital anatomy perceptions is unknown, and there is a paucity of studies examining women. AIM: We assessed the relationship between genital satisfaction, survey respondent sexual activity, and perceptions of anatomy and function. METHODS: A 54-item REDCap survey was distributed to any-gendered volunteers ≥18 years of age through ResearchMatch from January to March 2023. Responses were split into (1) high PGS and (2) low PGS. Analysis was performed using chi-square tests on survey responses and a Mann Whitney U test on median satisfaction level. OUTCOMES: Outcomes were genital anatomy perceptions, sexual activity, and respondents' PGS. RESULTS: Of the 649 respondents who started the survey, 560 (86.3%) completed it. Median PGS was 7 of 10, forming subgroups of high (≥7 of 10) satisfaction (n = 317 of 560 [56.6%]) and low (<7 of 10) satisfaction (n = 243 of 560 [43.4%]). The mean age was 45.8 ± 16.8 years, and demographics were notable for 72.1% women (n = 404 of 560), 83.2% White (n = 466 of 560), 47.9% married (n = 268 of 560), and 75.5% bachelor's degree holders (n = 423 of 560). Comparing high- and low-PGS groups, more low-PGS respondents felt normal flaccid penis length to be <2 inches (11.1% vs 5.1%; P = .008). High-PGS respondents more often responded that it is normal for women to have orgasms over half the time (20.8% vs 13.2%; P = .0002) or to identify as being sexually active (81.1% vs 71.6%; P = .008). Women were more likely than men to report larger normal testicle sizes as 60.1 to 90 mL (24.5% vs 10.3%; P < .0001), whereas more men felt that normal testicle size was 7 to 15 mL (26.3% vs 11.4%; P < .0001). Orgasm length perceptions also differed: more women felt female orgasm length was 2.6 to 5 seconds (36.6% vs 16.7%; P < .0001), and more men believed female orgasms to be longer, at 7.6 to 10 seconds (29.5% vs 17.3%; P = .002), 10.1 to 12.5 seconds (11.5% vs 5.2%; P = .0008), and >12.5 seconds (12.2% vs 5.7%; P = .009). Respondents' views on their genitalia differed by gender, with women more likely to feel that their genitals are normal compared with men (89.4% vs 75.0%; P < .0001). CLINICAL IMPLICATIONS: PGS may be a useful screening tool given its association with sexual activity. STRENGTHS AND LIMITATIONS: Our large-scale survey assesses public perceptions of genital anatomy and function. Limitations include a lack of gender nonbinary perceptions. CONCLUSION: Gender and PGS interact with perceptions of male anatomy and female sexual activity, and the frequency of sexual activity was higher among high-PGS respondents; however, the direction of these interactions remains unclear and requires future causal analysis.

Critically Evaluating the Role for Postoperative Antibiotics in Patients Undergoing Urethroplasty with Buccal Mucosa Graft: A Claims Database Analysis.

OBJECTIVES: To compare outcomes among patients undergoing first-time urethroplasty with buccal mucosa graft (BMG) who receive post-operative antibiotics versus those who do not. METHODS: A retrospective cohort study was conducted using the TriNetX claims database between 2008-2022. Using CPT, ICD10, and LOINC codes, patients >18 years old undergoing primary urethroplasty with BMG who received an outpatient prescription for antibiotics between post-operative day 0-30 or did not were queried. Patients with positive pre-operative urine culture or urinary tract infection (UTI) within 30 days pre-operatively were excluded. Surgical outcomes included 5-year revision rates and revision-free survival. Safety outcomes included new UTI within 30 days, surgical site infection (SSI) within 90 days, or Clostridium difficile infection within 30 days of urethroplasty. RESULTS: We identified 884 patients (81% antibiotic cohort, 19% non-antibiotic cohort) that met inclusion criteria. Age at time of urethroplasty, suprapubic tube presence, and pre-existing medical comorbidities were comparable between cohorts (Table 1A). There was no difference in 5-year rates and revision-free survival for endoscopic revision (11.5% vs. 9.5%, RR 1.2, 95% CI [0.7, 2.0], RFS log-rank p=0.6), re-do urethroplasty (12.9% vs. 13.7%, RR 0.9, 95% CI [0.6, 1.5], RFS log-rank p=0.7), or all-cause revision (19.8% vs. 17.7%, RR 1.1, 95% CI [0.8, 1.6], p=0.5) between groups. Post-operative rates of UTI, SSI, and Clostridium difficile infection were similar between groups. CONCLUSIONS: In this large retrospective cohort study of patients undergoing urethroplasty with BMG, we observed no significant benefit from use of post-operative antibiotics on long-term revision rates or perioperative infectious complications.

Associations of Social Support With Physical and Mental Health Symptom Burden After COVID-19 Hospitalization Among Older Adults.

BACKGROUND: Despite significant support system disruptions during the coronavirus 2019 (COVID-19) pandemic, little is known about the relationship between social support and symptom burden among older adults following COVID-19 hospitalization. METHODS: From a prospective cohort of 341 community-living persons aged ≥60 years hospitalized with COVID-19 between June 2020 and June 2021 who underwent follow-up at 1, 3, and 6 months after discharge, we identified 311 participants with ≥1 follow-up assessment. Social support prehospitalization was ascertained using a 5-item version of the Medical Outcomes Study Social Support Survey (range, 5-25), with low social support defined as a score ≤15. At hospitalization and each follow-up assessment, 14 physical symptoms were assessed using a modified Edmonton Symptom Assessment System inclusive of COVID-19-relevant symptoms. Mental health symptoms were assessed using Patient Health Questionnaire-4. Longitudinal associations between social support and physical and mental health symptoms, respectively, were evaluated through multivariable regression. RESULTS: Participants' mean age was 71.3 years (standard deviation, 8.5), 52.4% were female, and 34.2% were of Black race or Hispanic ethnicity. 11.8% reported low social support. Over the 6-month follow-up period, low social support was independently associated with higher burden of physical symptoms (adjusted rate ratio [aRR], 1.26; 95% confidence interval [CI], 1.05-1.52), but not mental health symptoms (aRR, 1.14; 95% CI, 0.85-1.53). CONCLUSIONS: Low social support is associated with greater physical, but not mental health, symptom burden among older survivors of COVID-19 hospitalization. Our findings suggest a potential need for social support screening and interventions to improve post-COVID-19 symptom management in this vulnerable group.

High-Intensity Care for Nursing Home Residents with Severe Dementia Hospitalized at the End of Life: A Mixed Methods Study.

OBJECTIVE: For nursing home residents with severe dementia, high-intensity medical treatment offers little possibility of benefit but has the potential to cause significant distress. Nevertheless, mechanical ventilation and intensive care unit (ICU) transfers have increased in this population. We sought to understand how and why such care is occurring. DESIGN: Mixed methods study, with retrospective collection of qualitative and quantitative data. SETTING: Department of Veterans Affairs (VA) hospitals. METHODS: Using the Minimum Data Set, we identified veterans aged ≥65 years who had severe dementia, lived in nursing homes, and died in 2013. We selected those who underwent mechanical ventilation or ICU transfer in the last 30 days of life. We restricted our sample to patients receiving care at VA hospitals because these hospitals share an electronic medical record, from which we collected structured information and constructed detailed narratives of how medical decisions were made. We used qualitative content analysis to identify distinct paths to high-intensity treatment in these narratives. RESULTS: Among 163 veterans, 41 (25.2%) underwent mechanical ventilation or ICU transfer. Their median age was 85 (IQR, 80-94), 97.6% were male, and 67.5% were non-Hispanic white. More than a quarter had living wills declining some or all treatment. There were 5 paths to high-intensity care. The most common (18 of 41 patients) involved families who struggled with decisions. Other patients (15 of 41) received high-intensity care reflexively, before discussion with a surrogate. Four patients had families who advocated repeatedly for aggressive treatment, against clinical recommendations. In 2 cases, information about the patient's preferences was erroneous or unavailable. In 2 cases, there was difficulty identifying a surrogate. CONCLUSIONS AND IMPLICATIONS: Our findings highlight the role of surrogates' difficulty with decision making and of health system-level factors in end-of-life ICU transfers and mechanical ventilation among nursing home residents with severe dementia.

Testing alternative hypotheses for the decline of cichlid fish in Lake Victoria using fish tooth time series from sediment cores.

Lake Victoria is well known for its high diversity of endemic fish species and provides livelihoods for millions of people. The lake garnered widespread attention during the twentieth century as major environmental and ecological changes modified the fish community with the extinction of approximately 40% of endemic cichlid species by the 1980s. Suggested causal factors include anthropogenic eutrophication, fishing, and introduced non-native species but their relative importance remains unresolved, partly because monitoring data started in the 1970s when changes were already underway. Here, for the first time, we reconstruct two time series, covering the last approximately 200 years, of fish assemblage using fish teeth preserved in lake sediments. Two sediment cores from the Mwanza Gulf of Lake Victoria, were subsampled continuously at an intra-decadal resolution, and teeth were identified to major taxa: Cyprinoidea, Haplochromini, Mochokidae and Oreochromini. None of the fossils could be confidently assigned to non-native Nile perch. Our data show significant decreases in haplochromine and oreochromine cichlid fish abundances that began long before the arrival of Nile perch. Cyprinoids, on the other hand, have generally been increasing. Our study is the first to reconstruct a time series of any fish assemblage in Lake Victoria extending deeper back in time than the past 50 years, helping shed light on the processes underlying Lake Victoria's biodiversity loss.

The Impact of Hypogonadism on Surgical Outcomes Following Primary Urethroplasty: Analysis of a Large Multi-institutional Database.

OBJECTIVE: To compare surgical outcomes among a cohort of eugonadal and hypogonadal patients undergoing primary urethroplasty (UP). METHODS: A retrospective cohort study was conducted using TriNetX between 2008-2023. Patients who were eugonadal and hypogonadal (symptoms plus testosterone <300 ng/dL) prior to UP were compared. A subgroup analysis of hypogonadal patients was performed to compare those with testosterone replacement therapy (TRT) vs TRT-naïve prior to UP. Propensity-score matching was used to adjust for differences in comorbidities. Outcomes were 5-year revision rates and revision-free survival for endoscopic revision and redo UP following primary UP. RESULTS: We identified 12,556 eugonadal and 488 hypogonadal patients (153 TRT+, 335 TRT-) undergoing UP. Median age at UP and follow-up was 55years and 5years, respectively. After propensity-score matching, we compared 477 eugonadal and 477 hypogonadal patients. Hypogonadal patients had a statistically significantly higher 5-year redo UP rate (11% vs 6%, relative risk [RR] 1.5 [95%CI, 1.2-2.2]; P = .01) when compared to eugonadal patients however there was no difference in 5-year rates of endoscopic revision (11% vs 11%, RR 1.0 [95%CI, 0.7-1.5]; P = 1.0). We observed no difference in 5-year revision-free survival time for endoscopic revision or redo UP between groups. Hypogonadal patients treated with TRT had a significantly higher 5-year redo UP rate (15% vs 7%, RR 1.8 [95%CI, 1.1-3.3]; P = .02) compared to hypogonadal patients that were TRT-naïve prior to UP. There was no difference in rates of endoscopic revision (14% vs 10%, RR 1.3 [95%CI, 0.7-2.4]; P = .2) between subgroups. CONCLUSION: Pre-existing hypogonadism may modestly adversely affect surgical outcomes following primary UP based on data from a large, retrospective cohort study.

Diagnostic uncertainty and decision-making in home-based primary care: A qualitative study of antibiotic prescribing.

BACKGROUND: Evaluating infection in home-based primary care is challenging, and these challenges may impact antibiotic prescribing. A refined understanding of antibiotic decision-making in this setting can inform strategies to promote antibiotic stewardship. This study investigated antibiotic decision-making by exploring the perspectives of clinicians in home-based primary care. METHODS: Clinicians from the Department of Veterans Affairs Home-Based Primary Care Program were recruited. Semi-structured interviews were conducted from June 2022 through September 2022 using a discussion guide. Transcripts were analyzed using grounded theory. The constant comparative method was used to develop a coding structure and to identify themes. RESULTS: Theoretical saturation was reached after 22 clinicians (physicians, n = 7; physician assistants, n = 2, advanced practice registered nurses, n = 13) from 19 programs were interviewed. Mean age was 48.5 ± 9.3 years, 91% were female, and 59% had ≥6 years of experience in home-based primary care. Participants reported uncertainty about the diagnosis of infection due to the characteristics of homebound patients (atypical presentations of disease, presence of multiple chronic conditions, presence of cognitive impairment) and the challenges of delivering medical care in the home (limited access to diagnostic testing, suboptimal quality of microbiological specimens, barriers to establishing remote access to the electronic health record). When faced with diagnostic uncertainty about infection, participants described many factors that influenced the decision to prescribe antibiotics, including those that promoted prescribing (desire to avoid hospitalization, pressure from caregivers, unreliable plans for follow-up) and those that inhibited prescribing (perceptions of antibiotic-associated harms, willingness to trial non-pharmacological interventions first, presence of caregivers who were trusted by clinicians to monitor symptoms). CONCLUSIONS: Clinicians face the difficult task of balancing diagnostic uncertainty with many competing considerations during the treatment of infection in home-based primary care. Recognizing these issues provides insight into strategies to promote antibiotic stewardship in home care settings.

Transperineal Versus Transrectal Magnetic Resonance Imaging-targeted and Systematic Prostate Biopsy to Prevent Infectious Complications: The PREVENT Randomized Trial.

BACKGROUND AND OBJECTIVE: The transrectal biopsy approach is traditionally used to detect prostate cancer. An alternative transperineal approach is historically performed under general anesthesia, but recent advances enable transperineal biopsy to be performed under local anesthesia. We sought to compare infectious complications of transperineal biopsy without antibiotic prophylaxis versus transrectal biopsy with targeted prophylaxis. METHODS: We assigned biopsy-naïve participants to undergo transperineal biopsy without antibiotic prophylaxis versus transrectal biopsy with targeted prophylaxis (rectal culture screening for fluoroquinolone-resistant bacteria and antibiotic targeting to culture and sensitivity results) through a multicenter, randomized trial. The primary outcome was post-biopsy infection captured by a prospective medical review and patient report on a 7-d survey. The secondary outcomes included cancer detection, noninfectious complications, and a numerical rating scale (0-10) for biopsy-related pain and discomfort during and 7-d after biopsy. KEY FINDINGS AND LIMITATIONS: A total of 658 participants were randomized, with zero transperineal versus four (1.4%) transrectal biopsy infections (difference -1.4%; 95% confidence interval [CI] -3.2%, 0.3%; p = 0.059). The rates of other complications were very low and similar. Importantly, detection of clinically significant cancer was similar (53% transperineal vs 50% transrectal, adjusted difference 2.0%; 95% CI -6.0, 10). Participants in the transperineal arm experienced worse periprocedural pain (0.6 adjusted difference [0-10 scale], 95% CI 0.2, 0.9), but the effect was small and resolved by 7-d. CONCLUSIONS AND CLINICAL IMPLICATIONS: Office-based transperineal biopsy is tolerable, does not compromise cancer detection, and did not result in infectious complications. Transrectal biopsy with targeted prophylaxis achieved similar infection rates, but requires rectal cultures and careful attention to antibiotic selection and administration. Consideration of these factors and antibiotic stewardship should guide clinical decision-making. PATIENT SUMMARY: In this multicenter randomized trial, we compare prostate biopsy infectious complications for the transperineal versus transrectal approach. The absence of infectious complications with transperineal biopsy without the use of preventative antibiotics is noteworthy, but not significantly different from transrectal biopsy with targeted antibiotic prophylaxis.

Atlantoaxial instability associated with ALDH18A1 mutation.

We report a 10-year-old boy with a de novo pathogenic variant in ALDH18A1, a rare form of metabolic cutis laxa, which was complicated by atlantoaxial instability and spinal cord compression following a fall from standing height. The patient required emergent cervical spine fusion and decompression followed by a 2-month hospitalization and rehabilitation. In addition to the core clinical features of joint and skin laxity, hypotonia, and developmental delays, we expand the connective tissue phenotype by adding a new potential feature of cervical spine instability. Patients with pathogenic variants in ALDH18A1 may warrant cervical spine screening to minimize possible morbidity. Neurosurgeons, geneticists, primary care providers, and families should be aware of the increased risk of severe cervical injury from minor trauma.

Retrospective Multicenter Observational Study of Immediate Voiding at End of Urinary Sphincter Surgery (REMOVE).

PURPOSE: Patients may remain catheterized after artificial urinary sphincter surgery to prevent urinary retention, despite a lack of evidence to support this practice. Our study aims to evaluate the feasibility of outpatient, catheter-free continence surgery using a multi-institutional database. We hypothesize that between catheterized controls and patients without a catheter, there would be no difference in the rate of urinary retention or postoperative complications. MATERIALS AND METHODS: We conducted a retrospective review of patients undergoing first-time artificial urinary sphincter placement from 2009-2021. Patients were stratified by postoperative catheter status into either no-catheter (leaving the procedure without a catheter) or catheter (postoperative indwelling catheter for ∼24 hours). The primary outcome, urinary retention, was defined as catheterization due to subjective voiding difficulty or documented postvoid residual over 250 mL. RESULTS: Our study identified 302 catheter and 123 no-catheter patients. Twenty (6.6%) catheter and 9 (7.3%) no-catheter patients developed urinary retention (P = .8). On multivariable analysis, controlling for age, cuff size, radiation history and surgeon, there was no statistically significant association between omitting a catheter and urinary retention (OR: 0.45, 95% CI: 0.13-1.58; P = .2). Furthermore, at 30 months follow-up, Kaplan-Meier survival analysis revealed that device survival was 70% (95% CI: 62%-76%) vs 69% (95% CI: 48%-82%) for the catheter and no-catheter group, respectively. CONCLUSIONS: In our multi-institutional cohort, overall retention rates were low (7%) in groups with a catheter and without. Obviating postoperative catheterization facilitates outpatient incontinence surgery without altering reoperation over medium-term follow-up.

Automatic detection of spatio-temporal signaling patterns in cell collectives.

Increasing experimental evidence points to the physiological importance of space-time correlations in signaling of cell collectives. From wound healing to epithelial homeostasis to morphogenesis, coordinated activation of biomolecules between cells allows the collectives to perform more complex tasks and to better tackle environmental challenges. To capture this information exchange and to advance new theories of emergent phenomena, we created ARCOS, a computational method to detect and quantify collective signaling. We demonstrate ARCOS on cell and organism collectives with space-time correlations on different scales in 2D and 3D. We made a new observation that oncogenic mutations in the MAPK/ERK and PIK3CA/Akt pathways of MCF10A epithelial cells hyperstimulate intercellular ERK activity waves that are largely dependent on matrix metalloproteinase intercellular signaling. ARCOS is open-source and available as R and Python packages. It also includes a plugin for the napari image viewer to interactively quantify collective phenomena without prior programming experience.

The Cell Tracking Challenge: 10 years of objective benchmarking.

The Cell Tracking Challenge is an ongoing benchmarking initiative that has become a reference in cell segmentation and tracking algorithm development. Here, we present a significant number of improvements introduced in the challenge since our 2017 report. These include the creation of a new segmentation-only benchmark, the enrichment of the dataset repository with new datasets that increase its diversity and complexity, and the creation of a silver standard reference corpus based on the most competitive results, which will be of particular interest for data-hungry deep learning-based strategies. Furthermore, we present the up-to-date cell segmentation and tracking leaderboards, an in-depth analysis of the relationship between the performance of the state-of-the-art methods and the properties of the datasets and annotations, and two novel, insightful studies about the generalizability and the reusability of top-performing methods. These studies provide critical practical conclusions for both developers and users of traditional and machine learning-based cell segmentation and tracking algorithms.

Antimicrobial resistance in Escherichia coli and Klebsiella pneumoniae urine isolates from a national sample of home-based primary care patients with dementia.

Annual prevalences of antimicrobial resistance among urine isolates (3,913 Escherichia coli isolates and 1,736 Klebsiella pneumoniae isolates) from home-based primary care patients with dementia were high between 2014 and 2018 (ciprofloxacin, 18%-23% and 5%-7%, respectively; multidrug resistance, 9%-11% and 5%-6%, respectively). Multidrug resistance varied by region. Additional studies of antimicrobial resistance in home-care settings are needed.

Patterns of Surgical Management of Male Stress Urinary Incontinence: Data From the AUA Quality Registry.

INTRODUCTION: We examined contemporary patterns in treatment of male stress urinary incontinence and identified predictors of undergoing specific surgical procedures. METHODS: Utilizing the AUA Quality Registry, we identified men with stress urinary incontinence utilizing International Classification of Disease codes and related procedures for stress urinary incontinence performed from 2014 to 2020 utilizing Current Procedural Terminology codes. Characteristics of the patient, surgeon, and practice were included in a multivariate analysis of predictors of management type. RESULTS: We identified 139,034 men with stress urinary incontinence in the AUA Quality Registry, of whom only 3.2% underwent surgical intervention during the study period. Artificial urinary sphincter was the most common procedure with 4,287/7,706 (56%) performed, followed by urethral sling with 2,368/7,706 (31%), and lastly urethral bulking with 1,040/7,706 (13%). There was no significant change by year in volume of each procedure performed during the study period. A large proportion of urethral bulking was performed by a disproportionately small number of practices; 5 high-volume practices performed 54% of the total urethral bulking over the study period. Open surgical procedure was more likely in patients with prior radical prostatectomy, urethroplasty, or care at an academic enter. Urethral bulking was more likely in patients with a history of bladder cancer or care by a surgeon of increasing age or female gender. CONCLUSIONS: Utilization of artificial urinary sphincter and urethral sling now exceeds utilization of urethral bulking for male stress urinary incontinence, though some practices continue to perform a disproportionate volume of bulking. Using data from the AUA Quality Registry, we can identify areas for quality improvement to facilitate guideline-adherent care.

The Cluster Structure Function.

For each partition of a data set into a given number of parts there is a partition such that every part is as much as possible a good model (an "algorithmic sufficient statistic") for the data in that part. Since this can be done for every number between one and the number of data, the result is a function, the cluster structure function. It maps the number of parts of a partition to values related to the deficiencies of being good models by the parts. Such a function starts with a value at least zero for no partition of the data set and descents to zero for the partition of the data set into singleton parts. The optimal clustering is the one selected by analyzing the cluster structure function. The theory behind the method is expressed in algorithmic information theory (Kolmogorov complexity). In practice the Kolmogorov complexities involved are approximated by a concrete compressor. We give examples using real data sets: the MNIST handwritten digits and the segmentation of real cells as used in stem cell research.

Robotic-Assisted Augmented Roof Ureteroplasty With Appendiceal Onlay Flap.

BACKGROUND: Mid-to-proximal ureteral strictures pose a surgical challenge that historically required ileal ureter substitution, downward nephropexy, or renal autotransplantation. Ureteral reconstruction techniques involving buccal mucosa or appendix have gained traction with success rates approaching 90%. OBJECTIVES: In this video we describe surgical technique for a robotic-assisted augmented roof ureteroplasty using an appendiceal onlay flap. MATERIALS AND METHODS: Our patient is a 45-year-old male with recurrent impacted ureteral stones requiring multiple right-sided interventions including ureteroscopy with laser lithotripsy, ureteral dilation, and laser incision of ureteral stricture. Despite adequate treatment of his stone disease, he had deterioration of his renal split function with worsening right hydroureteronephrosis to the level of the mid-to-proximal ureter consistent with failed endoscopic management of his stricture. We proceeded with simultaneous endoscopic evaluation and robotic repair with plan for either ureteroureterostomy or augmented roof ureteroplasty using buccal mucosa or an appendiceal flap. RESULTS: Reteroscopy and retrograde pyelogram revealed a 2-3 cm near-obliterative stricture in the mid-to-proximal ureter. The ureteroscope was left in situ and the patient was placed in the modified flank position to allow concurrent endoscopic access during reconstruction. The right colon was reflected revealing significant scar tissue overlying the ureter. With the ureteroscope in situ, we utilized firefly imaging to aid in our dissection. The ureter was spatulated and mucosa of the diseased segment of ureter excised in a nontransecting manner. The mucosal edges of the posterior ureter were re-approximated with the ureteral backing left in place. Intraoperatively, we identified a healthy, robust appearing appendix and thus planned for an appendiceal onlay flap. If an atretic or diseased appendix was encountered, a buccal mucosa graft with omental wrap would be utilized. The appendix was harvested on its mesentery, spatulated, and interposed in a pro-peristaltic fashion. A tension-free anastomosis was performed between ureteral mucosa and the open appendix flap. A double-J stent was placed under direct vision and Indocyanine Green (ICG) green was used to evaluate blood supply to the margins of the ureter and the appendix flap. The stent was removed 6 weeks postoperatively, and on 3-month follow-up imaging he had resolution of his right hydroureteronephrosis and has had no further episodes of stone formation, infections, or flank pain with 8-month follow-up. CONCLUSION: Augmented roof ureteroplasty with appendiceal onlay is a valuable tool in the urologists arsenal of reconstructive techniques. Use of intraoperative ureteroscopy with firefly imaging can aid in delineating anatomy during difficult ureteral dissections.

Navigating the COVID-19 pandemic together: Discussions between persons with early-stage dementia and their adult children.

OBJECTIVES: Studies have separately examined the health impacts of the COVID-19 pandemic on persons with dementia and their caregivers. Less attention has been paid to the social and emotional impacts of the pandemic in this population or how these individuals are mutually coping with the pandemic. Guided by the social citizenship theory, this qualitative study sought to characterize how persons with dementia and their adult children are coping during this time with a focus on the strengths demonstrated by persons with dementia. METHODS: Participants were 43 dyads of individuals aged 55 and older with early-stage dementia and their adult children. Discussions between parent-child dyads were recorded. Using reflexive thematic analysis, themes related to social and emotional impacts of the pandemic and coping strategies were identified. RESULTS: Adult children shared with their parents how the pandemic resulted in reduced social engagement and challenging work arrangements. Dyads described how the pandemic positively impacted their relationship, allowing some of them to spend more time together. In coping with the pandemic, adult children provided instrumental support to their parents and parents reciprocated with emotional support. Participants also coped by making meaning of their situation during discussions. CONCLUSIONS: Findings characterize the resilience of persons with dementia and the mutuality of the relationship between both members of the care partner dyad, as both parents and adult children offered support to one another. Facilitating dyadic discussions may be a cost-effective way to sustain social connections and offer ongoing coping support through the pandemic or other challenging circumstances.

EPA's Unprecedented Interim Drinking Water Health Advisories for PFOA and PFOS.

Per- and polyfluoroalkyl substances (PFAS) are persistent and widely distributed in the environment from commercial products and waste process residues, including in surface waters usually at low parts per trillion (ppt) levels. Groundwaters near contaminated locations can have higher parts per trillion or parts per billion (ppb) concentrations. Interim EPA Drinking Water Health Advisories (HAs) for perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) that were originally 70 ppt were recently reduced to 0.004 and 0.020 ppt, respectively. Final HAs for perfluorobutane sulfonic acid and its potassium salt (PFBS) and hexafluoropropylene oxide (HFPO) dimer acid and its ammonium salt ("GenX chemicals") were established at 2000 and 10 ppt, respectively. The minimum reporting levels (MRLs) for PFOA and PFOS are currently 4 ppt. The scientific basis for these very low and unmeasurable HA values for PFOA and PFOS is debatable and up to about five orders of magnitude below many other worldwide national recommendations (e.g., Australia, UK, Canada), which are in the range of 100 ppt and above.
