School reopenings, COVID-19, and employment.

Using a panel of United States counties, this study compares outcomes before and during the 2020-2021 school year between locations that started K-12 instruction on campus, remotely, or through a hybrid approach. Corroborating recent studies, we find comparatively larger increases of COVID-19 cases and deaths in locations using any in-person instruction. Within the same empirical framework, we present robust new evidence that employment was unaffected by this choice, even in counties with more vulnerable populations. We posit that opening schools did not improve employment due to policy uncertainty, supported by the fact that one-quarter of schools changed teaching methods mid-year.

Optimizing Nutrition Prior to Radical Cystectomy.

PURPOSE OF REVIEW: Malnutrition in a prevalent problem in patients undergoing radical cystectomy. Preoperative malnutrition has been shown to contribute to increased rates of postoperative complications. Given the significant morbidity and mortality of the procedure of radical cystectomy, there is potential for improvement in patient outcomes by nutritional intervention. RECENT FINDINGS: Prospective studies have demonstrated a reduction in postoperative infection rates in patients who receive supplemental immunonutrition prior to major surgery including radical cystectomy. These initial evaluations of nutritional optimization show significant potential for improved outcomes. Additionally, several studies using enhanced recovery after surgery protocols, which include a preoperative nutritional component, have shown a benefit in reducing length of stay. Emerging literature has shown the benefits of preoperative immunonutrition in improving postoperative outcomes of radical cystectomy. However, further work is needed to determine the best mechanism to optimize nutrition prior to radical cystectomy.

Comparison of complications from radical cystectomy between old-old versus oldest-old patients.

INTRODUCTION: The purpose of this study was to evaluate and compare complications after radical cystectomy in patients aged ≥75 years. MATERIALS AND METHODS: 251 patients aged 75-95 years (median 79) underwent radical cystectomy between 2000 and 2012 at four institutions. The patients were divided into two groups: ≥75-84 years of age (group 1) versus ≥85 years of age (group 2). Comorbidities, body mass index, and complications were obtained retrospectively, except at the Central Hospital of Bolzano and Weill Cornell Medical Center, which collected data prospectively. Cancer-specific survival, overall mortality, hospital stay, clinical outcome and complications were assessed. Complications were categorized using the Clavien-Dindo classification reporting system. The mean follow-up was 21 months. RESULTS: The median hospital stay was 17 (2-91) days. Perioperative Clavien-Dindo grade ≥III complications were seen in 24.1% (48/199) of group 1 patients and 19.2% (10/52) of group 2 patients (p = 0.045). 30- and 90-day mortality was 4.5 and 13.5% in group 1 and 6.5 and 32.3% in group 2, respectively. Only the 90-day mortality rate was statistically significant (p < 0.05) between the two groups. The 3-year overall survival was 40% in group 1 and 34% in group 2. The 3-year cancer-specific survival was 52% in group 1 and 50% in group 2. CONCLUSIONS: We evaluated a large series of elderly (≥75 years) patients undergoing radical cystectomy at four institutions. Comparing patients aged ≥75-84 and ≥85 years revealed no significant difference in complications, 30-day mortality, overall and cancer-specific survival rates. Only 90-day mortality rates were significantly higher in the ≥85-year-old patients.

Procedures needed to maintain functionality of adult continent catheterizable channels: a comparison of continent cutaneous ileal cecocystoplasty with tunneled catheterizable channels.

PURPOSE: We compared the outcomes of various adult continent catheterizable channels in a multi-institutional setting. MATERIALS AND METHODS: We retrospectively reviewed the records of all adults who underwent construction of a continent catheterizable channel at our 4 institutions from 2004 to 2013 and who had at least 6 months of followup. Patients were stratified by channel type, including continent cutaneous ileal cecocystoplasty or tunneled cutaneous channel, eg appendicovesicostomy, Monti channel, etc. The primary study outcome was the need for a secondary procedure to correct stomal leakage, catheterizable channel obstruction or stomal stenosis. Secondary outcomes were patient reported leakage and 30-day postoperative complications. We used Firth logistic regression to control for the heterogeneity induced by multiple institutions. RESULTS: A total of 61 patients were included in study, of whom 31 underwent continent cutaneous ileal cecocystoplasty. Mean age was 41.4 years (range 22 to 76). Median followup was 16 months. More patients with a tunneled channel required a secondary procedure than those with cecocystoplasty (15 of 30 or 50% vs 4 of 31 or 13%, OR 6.4, 95% CI 1.8-28). The total number of required secondary procedures was also greater for tunneled channels than for cecocystoplasty (27 vs 4). Of patients with cecocystoplasty 29% reported stomal leakage compared with 43% of those with a tunneled channel (p = 0.12). A high rate of postoperative complications was observed regardless of technique, including 40% for channels and 51.7% for cecocystoplasty. CONCLUSIONS: Patients with continent cutaneous ileal cecocystoplasty undergo fewer interventions to maintain the catheterizable channel than patients with a tunneled continent catheterizable channel.

Conditional cash lotteries increase COVID-19 vaccination rates.

Conditional cash lotteries (CCLs) provide people with opportunities to win monetary prizes only if they make specific behavioral changes. We conduct a case study of Ohio's Vax-A-Million initiative, the first CCL targeting COVID-19 vaccinations. Forming a synthetic control from other states, we find that Ohios incentive scheme increases the vaccinated share of state population by 1.5 percent (0.7 pp), costing sixty-eight dollars per person persuaded to vaccinate. We show this causes significant reductions in COVID-19, preventing at least one infection for every six vaccinations that the lottery had successfully encouraged. These findings are promising for similar CCL public health initiatives.

Association between the lengths of excised obstructed vas deferens segments at the time of vasovasostomy and surgical outcomes.

OBJECTIVE: This study aimed to determine whether the length of the excised obstructed vas deferens at vasovasostomy (VV) performed for fertility is associated with semen parameters and/or pregnancy outcomes postoperatively. MATERIAL AND METHODS: The patients who underwent a VV at our institution from September 2004 to December 2018 were contacted via questionnaire and a chart review was performed. Linear and logistic regression models were used to determine the associations between the length of the obstructed vas deferens removed and postoperative outcomes including sperm concentration, motility, and successful pregnancy after reversal. RESULTS: A total of 83/170 questionnaires were returned. After exclusions, a total of 35 patients were included for analysis. The mean age of the patients at the time of surgery was 40.1 years and the mean time since vasectomy 9.3 years. The mean length of the obstructed vas deferens removed during VV was 2.25 cm. The longer the vas deferens segments removed, the more significant was the increase in sperm motility at 3 and 9 months postoperatively (p=0.011 and 0.008, respectively), but decreased sperm motility at 6 months (p=0.029). In 75.9% of the patients, sperm was present postoperatively, 23.2% achieved pregnancy through natural conception, and 55.8% achieved pregnancy using assisted reproductive techniques. There was no significant relationship between the length of the vas deferens removed and sperm concentration or pregnancy achieved after surgery. CONCLUSION: In this cohort, the length of the excised obstructed vas deferens at VV was associated with improved sperm motility at 3 and 9 months postoperatively but not with pregnancy outcomes.

Large para-testicular intra-scrotal malignant peripheral nerve sheath tumor managed with radical penectomy: A case report.

Neurofibromatosis 1 is a relatively rare genetic disease characterized by widespread neurofibromas originating from the peripheral nervous system. Most growths are benign, but some carry a risk of transformation to malignant peripheral nerve sheath tumors. Although these growths can be found anywhere in the body, they are rarely found in the male external genitalia. This report discusses a case of a 25-year-old male patient with neurofibromatosis 1 presenting with a scrotal mass found to have a very large para-testicular intra-scrotal malignant peripheral nerve sheath tumor that required testicle-sparing radical penectomy.

Feeding Children and Maintaining Food Service Operations during COVID-19: A Mixed Methods Investigation of Implementation and Financial Challenges.

The United States Department of Agriculture (USDA) National School Lunch and Breakfast Programs are critical for the health and food security of U.S. schoolchildren, but access to these programs was disrupted by COVID-19 pandemic-related school closures in spring 2020. While temporary policy changes to the programs enabled school food authorities (SFAs) to pivot towards distributing meals throughout their communities instead of within school buildings, SFAs faced complex challenges during COVID-19 with minimal external support. This mixed methods study investigates the implementation and financial challenges experienced by twelve of the largest urban SFAs in the U.S. during COVID-19. We conducted semi-structured interviews with SFA leaders and analyzed alongside quantitative financial data. We found that SFAs reconfigured their usual operations with nearly no preparation time while simultaneously trying to keep staff from contracting COVID-19, accommodate stakeholders with sometimes competing priorities, and remain financially solvent. Because student participation was much lower than during regular times, and revenue is tied to the number of meals served, SFAs saw drastic decreases in revenue even as they carried regular operating costs. For future crises, disaster preparedness plans that help SFAs better navigate the switch to financially viable community distribution methods are needed.

Cell cycle progression score has potential prognostic value for stage T1 renal cell carcinomas.

BACKGROUND: There is an ongoing effort to identify a biomarker which predicts metastatic progression of renal cell carcinoma (RCC). OBJECTIVE: To evaluate the utility of the cell cycle progression (CCP) score biomarker in predicting metastasis in RCC after local resection of pathologic T1 disease. DESIGN, SETTING, AND PARTICIPANTS: Pathologic T1 tumors at the University of Iowa were reviewed in patients who had a radical or partial nephrectomy between 1995 and 2010. Patients with known or suspected metastasis, who had received chemotherapy, or who developed metastasis within 60 days of surgery were excluded. Final analysis included 163 patients with RCC who developed metastasis or a new primary within 5 years after surgery or had been followed for 5 years without developing metastasis. INTERVENTION(S): Expression levels of 31 cell cycle genes and 15 control genes from the tumor were measured and reported as a CCP score. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The sensitivity, specificity, positive predictive value, and negative predictive value for the development of a metastasis or new primary within 5 years of resection was calculated for varying CCP score cutoffs. RESULTS AND LIMITATIONS: A total of 4 (2.5%) patients developed metastasis and 7 (4.3%) developed a new primary renal tumor. A CCP score of >-0.25 had a 100% sensitivity and 43% specificity for predicting metastatic progression. A CCP score of >-0.7 had a 100% sensitivity and 20% specificity for predicting the development of a new renal primary. CONCLUSIONS: The CCP score has potential prognostic value in predicting metastatic progression and might be a useful tool for the management of patients with RCC. PATIENT SUMMARY: In this study we looked at the utility of a particular gene expression profile from kidney tumors. We found that this gene expression test has the potential to identify tumors at risk of metastasis and thus could be a useful tool in the management of patients with kidney tumors.

Elderly patients undergoing cystectomy, comparing preoperative American Society of Anesthesiology and Eastern Cooperative Oncology Group scores and operative approaches.

OBJECTIVE: To evaluate preoperative scoring systems and operative management and their relation to complications in patients older than 75 years undergoing cystectomy at two academic institutions. METHODS: In total, 212 patients aged 75-95 years with muscle invasive bladder cancer underwent cystectomy at the University of Utah and Central Hospital of Bolzano, Italy. The rates of Grade 3 Clavien-Dindo complications and above in radical cystectomy patients (n = 199) were compared using Eastern Cooperative Oncology Group Scores and American Society of Anesthesiologists Physical Status Classification. The rates of Grade 3 Clavien-Dindo complications and above were also compared by urinary diversion type. Logistic regression was used to control for source institution. RESULTS: In total, 199 cases were included in the primary analysis. Neither of the preoperative scoring systems were predictive for identification of radical cystectomy patients with ⩾Grade 3 Clavien-Dindo complications. In secondary analysis (n = 212, including partial cystectomy), none of the urinary diversion types associated with radical cystectomy had a significantly different rate of complications. However, partial cystectomy (n = 13) had a significantly lower rate of complications. CONCLUSION: Complication rates among elderly patients undergoing cystectomy for muscle invasive bladder cancer were very high. For patients who are approved for surgery after the history and physical exam, none of our objective metrics adequately predicted operative risk. A unique diversion procedure described by the Bolzano group, uretero-ureterocutaneostomy, had equivalent complication rates to the more common diversion procedures. It also appears based on outcomes in this cohort that partial cystectomy is a particularly favorable option within the elderly population in terms of perioperative morbidity.

A 26-Year-Old Male with a 14-Year History of Left Intermittent Testicular Torsion Treated with Self-Manual Reduction.

Intermittent testicular torsion presents with recurrent episodes of severe unilateral testicular pain with resolution of symptoms between episodes. We present a case of a 26-year-old man with a 14-year history of intermittent testicular pain presenting to the urology clinic for elective surgical evaluation. He reported monthly symptoms for many years and had learned to manually reduce the torsion with each episode. Diagnosis of intermittent testicular torsion was made based on patient history and treatment with bilateral orchiopexy resulted in complete symptom resolution and without any loss of testicular function.

Symptom management with massage and acupuncture in postoperative cancer patients: a randomized controlled trial.

The level of evidence for the use of acupuncture and massage for the management of perioperative symptoms in cancer patients is encouraging but inconclusive. We conducted a randomized, controlled trial assessing the effect of massage and acupuncture added to usual care vs. usual care alone in postoperative cancer patients. Cancer patients undergoing surgery were randomly assigned to receive either massage and acupuncture on postoperative Days 1 and 2 in addition to usual care, or usual care alone, and were followed over three days. Patients' pain, nausea, vomiting, and mood were assessed at four time points. Data on health care utilization were collected. Analyses were done by mixed-effects regression analyses for repeated measures. One hundred fifty of 180 consecutively approached cancer patients were eligible and consented before surgery. Twelve patients rescheduled or declined after surgery, and 138 patients were randomly assigned in a 2:1 scheme to receive massage and acupuncture (n=93) or to receive usual care only (n=45). Participants in the intervention group experienced a decrease of 1.4 points on a 0-10 pain scale, compared to 0.6 in the control group (P=0.038), and a decrease in depressive mood of 0.4 (on a scale of 1-5) compared to +/-0 in the control group (P=0.003). Providing massage and acupuncture in addition to usual care resulted in decreased pain and depressive mood among postoperative cancer patients when compared with usual care alone. These findings merit independent confirmation using larger sample sizes and attention control.

Safety and efficiency of an anti-(+)-methamphetamine monoclonal antibody in the protection against cardiovascular and central nervous system effects of (+)-methamphetamine in rats.

The purpose of these studies was to determine if a high-affinity, anti-(+)-methamphetamine (METH) monoclonal antibody (mAb6H4; KD=11 nM) protects against METH-induced central nervous and cardiovascular system effects in rats. Rats (n=5 per group) received one of three anti-METH mAb6H4 doses, equal to 0.32, 0.56 or 1 times the mole equivalent (mol-eq) amount of METH in the body following a 1 mg/kg i.v. METH dose. Each rat was challenged with METH (1 mg/kg, i.v.) 1 and 4 days after the anti-METH mAb dose. The 1 mol-eq anti-METH mAb dose significantly reduced the duration of METH-induced locomotor activity (horizontal locomotion and rearing events), heart rate and blood pressure effects from 2 to 3 h to about an hour. This resulted in a significant reduction in total locomotor activity and the area under the hemodynamic effect vs. time curve for heart rate and blood pressure. In addition, the time to peak locomotor activity was decreased after the 1 mol-eq mAb dose vs. the lower doses. These changes were limited to the first METH challenge. The responses to the second METH challenge were not different from baseline. The peak hemodynamic and locomotor activity values were unchanged after both challenges. These results indicate anti-METH mAb6H4 can safely reduce the hemodynamic and locomotor effects of METH given one day after anti-METH IgG, and that the mAb is safe when administered in the absence of METH. These results are important because they indicate these antibody medications have simultaneous beneficial effects in multiple organ systems.

Direct antilymphoma activity of novel, first-generation "antibody mimics" that bind HLA-DR10-positive non-Hodgkin's lymphoma cells.

A first-generation series of novel small molecules, collectively known as selective high-affinity ligands (SHALs), were designed and synthesized to mimic the binding of Lym-1, a monoclonal antibody (mAb) shown to be an effective cytotoxic and radionuclide carrier molecule for targeting non-Hodgkin's lymphoma (NHL). Created as radionuclide targeting molecules, these SHALs were intended to have the human leukocyte antigen-DR (HLA-DR) selectivity of Lym-1 mAb and the pharmacokinetics of a small molecule. Because of the remarkable bioactivity of Lym-1 in vitro, the direct antilymphoma activity of three of these SHALs was tested. Two of these SHALs were bidentate and consisted of two ligands connected to the carboxyl and amino groups of lysine and polyethylene glycol (PEG); the third SHAL was a dimeric version of one of the former two SHALs linked with PEG. The three SHALs tested were: LeLPLDB, that contained one deoxycholate and one 5-leu-enkephalin as ligands; (LeacPLD)2LPB, a bis version of LeLPLDB intended to improve "functional affinity"; and ItPLDB, that contained the ligands, deoxycholate and triiodothyronine. Micromolar concentrations of all three SHALs showed binding to Raji, an HLA-DR10-positive human malignant B-cell line but no binding to CEM or Jurkat's, HLA-DR10-negative malignant T-cell lines. Additionally, the Raji cell membrane distributions of all three SHALs and of Lym-1 were remarkably similar. Unlike Lym-1, which causes substantial growth inhibition and cell death in NHL cell lines, these SHALs had no direct antilymphoma activity. In summary, three first-generation SHALs lacked direct antilymphoma activity, although they had selective NHL B-cell binding like Lym-1 mAb. Because of their small size, these SHALs have potential as radionuclide carrier substitutes for Lym-1 mAb to target the HLA-DR10 NHL-related cell-surface protein.

Berberine sensitizes human glioma cells, but not normal glial cells, to ionizing radiation in vitro.

The identification of nontoxic agents that can enhance the efficacy of postoperative radiotherapy for patients with glioblastoma multiforme (GBM) remains a challenge in oncology. We evaluated human GBM cell lines for their responsiveness to berberine, an alkaloid compound used commonly in Asia as an antibiotic. In experiments measuring clonogenic survival, treatment with a nontoxic dose of berberine rendered GBM cells more sensitive than vehicle-treated control cells to x-rays. Such radiosensitization was not observed in parallel experiments with primary human glial cultures. These data suggest that berberine could be integrated with postoperative radiotherapy to selectively promote residual GBM tumor cell death

Possible influence of infrasound on glioma cell response to chemotherapy: a pilot study.

OBJECTIVE: To assess the response of cultured human tumor cells to infrasound in combination with conventional anticancer agents using an infrasound-emitting apparatus marketed as a therapeutic device. DESIGN: Two pilot experiments measured proliferation of cultured brain tumor cells exposed to three treatment conditions: infrasound emission alone, infrasound in combination with the chemotherapy 5-fluorouracil (5-FU), and infrasound in combination with ionizing radiation. Results from each experimental condition were compared to those from appropriate control conditions. OUTCOME MEASURE: A standard colony-forming efficiency assay was used to assess tumor cell proliferation. RESULTS: Tumor cell proliferation was not significantly altered by treatment with infrasound alone, nor did infrasound appear to influence cellular response to x-rays. There was a significant interaction between 5-FU and infrasound (P < 0.0001), however, evident in decreased colony formation. CONCLUSION: Further research is warranted to assess potential synergism between infrasound and 5-FU against tumor cell proliferation, and to investigate the possible therapeutic use of infrasound.

Biofield perception: a series of pilot studies with cultured human cells.

BACKGROUND: Energy medicine (EM) practitioners often claim to be able to perceive an energetic field associated with the body and to be able to use this skill to diagnose illness and guide treatment strategies. If a biofield associated with cells growing in culture is perceptible to EM practitioners, such an in vitro model would be a useful resource for investigating biofield perception that would provide some unique advantages over clinical models. OBJECTIVE: To evaluate whether EM practitioners can perceive the presence of cultured human cells without visual cues. DESIGN: Three randomized double-blinded pilot studies were used to evaluate the ability of participants to distinguish a flask containing cancer cells growing in culture medium from a flask containing either culture medium or sterile water. Each study consisted of six independent experiments: three with EM practitioners and three with non-practitioners. The number of independent trials for each experiment was estimated by statistical power analyses of the design. Practitioners' feedback from the first two studies was used to revise the protocol for the subsequent studies, with the intent to eliminate potential problems in making this distinction. Labeled flasks ("cells" and "no-cells") were added to serve as references for comparison in the second study and the number of experimental trials was reduced in the third study. SUBJECTS: Eight experienced EM practitioners and nine non-practitioners (laboratory personnel with no EM training). SETTING: A basic science laboratory and office at an academic medical center. OUTCOME MEASURES: In the first 2 studies, we determined the number of correct determinations in a series of 34 trials. In the third study, we determined the number of correct determinations in a series of 10 trials. RESULTS: All participants performed at the level expected by chance. CONCLUSION: While preliminary and inconclusive, these pilot studies found no evidence that EM practitioners can perceive a biofield associated with cancer cells growing in culture.

Urologic problems in spina bifida patients transitioning to adult care.

OBJECTIVE: To identify the urologic needs of adult patients with spina bifida (SB) at the time of their transition from pediatric to adult care. We hypothesized that delays in transition to adult care would be associated with higher rates of active problems. METHODS: We retrospectively reviewed patients seen at adult dedicated SB clinics at the Universities of Utah and Minnesota from April 2011 to April 2012. We reviewed bladder management, urologic problems, time from last urologic care, and necessary interventions. RESULTS: We identified 65 patients from these clinics with SB. The mean age was 30.6 years (standard deviation, 11.3). The median time since last urologic evaluation at Utah and Minnesota was 17 months and 12 months, respectively (range 1 month-10 years). Fifty-five patients (85%) reported a urologic problem at the time of their visit. Urinary incontinence was most common in 34 (52%), followed by recurrent urinary tract infection in 22 (34%), catheterization troubles in 8 (12%), and calculi in 6 (9%). Sixty-three patients (97%) required some sort of intervention. These were diagnostic (cystoscopy, ultrasonography, computed tomography scan, urodynamics) in 50 patients (77%), surgical (urinary diversion, onabotulinum toxin A injection, stone surgery, and so forth) in 22 (34%), and medical (antimicrobial prophylaxis, bladder irrigations, anticholinergics, self-catheterization) in 16 (25%). There was no association between longer transition times and higher rates of active problems. CONCLUSION: On presentation to adult SB clinics, patients had many active urologic problems and operative management was often needed; however, there was no association between longer transition times and higher rates of active problems.

Use of a polytetrafluoroethylene (GORE-TEX) bolster to close the renal parenchymal defect during open partial nephrectomy.

INTRODUCTION: Numerous surgical techniques have been described to facilitate closure of the renal parenchymal defect. We sought to describe the operative technique and define the safety and efficacy of using an expanded polytetrafluoroethylene (GORE-TEX; WL Gore and Associates, Flagstaff, AZ) bolster to aid in closure of the renal parenchymal defect at the time of open partial nephrectomy (OPN). TECHNICAL CONSIDERATIONS: A retrospective review of 175 patients who underwent an OPN using an expanded polytetrafluoroethylene (ePTFE) bolster at the Huntsman Cancer Hospital, University of Utah and Salt Lake City Veterans Affairs Medical Center from March 2005 to February 2013 was conducted. Postoperative complications occurring within 90 days were graded using the Clavien grading system. CONCLUSION: Overall, 57 patients (32.6%) experienced a postoperative complication. Fifteen patients (8.5%) had a Clavien ≥ grade-III complication. Ten patients (5.7%) received blood transfusions. Urine leak requiring intervention occurred in 2 patients (1.1%). Delayed hemorrhage requiring nephrectomy and pseudoaneurysm formation were rare, occurring in 1 patient each (0.6%). Infection of the ePTFE material occurred in 2 patients (1.1%). In both cases, it was explanted without requiring nephrectomy. The use of an ePTFE bolster is an effective and safe method of closing the renal parenchymal defect after OPN with an acceptable 90-day postoperative complication rate and a low risk of infection.
