RESUMO
Understanding how interventions reduce psychological distress in patients with prostate cancer is crucial for improving patient care. This study examined the roles of self-efficacy, illness perceptions, and heart rhythm coherence in mediating the effects of the Prostate Cancer Patient Empowerment Program (PC-PEP) on psychological distress compared to standard care. In a randomized controlled trial, 128 patients were assigned to either the PC-PEP intervention or standard care. The PC-PEP, a six-month program emphasizing daily healthy living habits, included relaxation and stress management, diet, exercise, pelvic floor muscle exercises, and strategies to improve relationships and intimacy, with daily activities supported by online resources and live sessions. Participants in the intervention group showed significant improvements in self-efficacy and specific illness perceptions, such as personal control and emotional response, compared to the control group. These factors mediated the relationship between the intervention and its psychological benefits, with self-efficacy accounting for 52% of the reduction in psychological distress. No significant differences in heart rhythm coherence were observed. This study highlights the critical role of self-efficacy and illness perceptions in enhancing psychological health in prostate cancer patients through the PC-PEP. The results underscore this program's effectiveness and the key mechanisms through which it operates. Given the high rates of distress among men undergoing prostate cancer treatments, these findings emphasize the importance of integrating the PC-PEP into clinical practice. The implementation of the PC-PEP in clinical settings can provide a structured approach to reducing psychological distress and improving overall patient well-being.
RESUMO
Purpose: This is a secondary analysis examining a six-month home-based Prostate Cancer-Patient Empowerment Program (PC-PEP) on patient-reported urinary, bowel, sexual, and hormonal function in men with curative prostate cancer (PC) against standard of care. Methods: In a crossover clinical trial, 128 men scheduled for PC surgery (n = 62) or radiotherapy with/without hormones (n = 66) were randomized to PC-PEP (n = 66) or waitlist-control and received the standard of care for 6 months, and then PC-PEP to the end of the year. PC-PEP included daily emails with video instructions, aerobic and strength training, dietary guidance, stress management, and social support, with an initial PFMT nurse consultation. Over 6 months, participants in the PC-PEP received optional text alerts (up to three times daily) reminding them to follow the PFMT video program, encompassing relaxation, quick-twitch, and endurance exercises; compliance was assessed weekly. Participants completed baseline, 6, and 12-month International Prostate Symptom Score (IPSS) and Expanded Prostate Cancer Index Composite (EPIC) questionnaires. Results: At 6 months, men in the PC-PEP reported improved urinary bother (IPSS, p = 0.004), continence (EPIC, p < 0.001), and irritation/obstruction function (p = 0.008) compared to controls, with sustained urinary continence benefits at 12 months (p = 0.002). Surgery patients in the waitlist-control group had 3.5 (95% CI: 1.2, 10, p = 0.024) times and 2.3 (95% CI: 0.82, 6.7, p = 0.11) times higher odds of moderate to severe urinary problems compared to PC-PEP at 6 and 12 months, respectively. Conclusions: PC-PEP significantly improves lower urinary tract symptoms, affirming its suitability for clinical integration alongside established mental health benefits in men with curative prostate cancer.
RESUMO
Background: The Prostate Cancer-Patient Empowerment Program (PC-PEP) is a six-month daily home-based program shown to improve mental health and urinary function. This secondary analysis explores weight loss in male PC-PEP participants. Methods: In a randomized clinical trial with 128 men undergoing curative prostate cancer (PC) treatment, 66 received 'early' PC-PEP, while 62 were assigned to the 'late' waitlist-control group, receiving 6 months of standard-of-care treatment followed by 6 months of PC-PEP. PC-PEP comprised 182 daily emails with video-based exercise and dietary (predominantly plant-based) education, live online events, and 30 min strength training routines (using body weight and elastic bands). Weight and height data were collected via online surveys (baseline, 6 months, and 12 months) including medical chart reviews. Adherence was tracked weekly. Results: No attrition or adverse events were reported. At 6 months, the early PC-PEP group experienced significant weight loss, averaging 2.7 kg (p < 0.001) compared to the waitlist-control group. Weight loss was noted in the late intervention group of PC-PEP, albeit less pronounced than in the early group. Early PC-PEP surgery patients lost on average 1.4 kg (SE = 0.65) from the trial's start to surgery day. High adherence to exercise and dietary recommendations was noted. Conclusions: PC-PEP led to significant weight loss in men undergoing curative prostate cancer treatment compared to standard-of-care.

Desktop 3D printers that operate by the fused deposition modeling (FDM) mechanism are known to release numerous hazardous volatile organic compounds (VOCs) during printing, including some with potential carcinogenic effects. Operating in a similar manner to FDM 3D printers, 3D pens have gained popularity recently from their ability to allow users to effortlessly draw in the air or create various 3D printed shapes while handling the device like a pen. In contrast to numerous modern 3D printers, 3D pens lack their own ventilation systems and are often used in settings with minimum airflow. Their operation makes users more vulnerable to VOC emissions, as the released VOCs are likely to be in the breathing zone. Consequently, monitoring VOCs released during the use of 3D pens is crucial. In this study, VOCs liberated while extruding acrylonitrile butadiene styrene (ABS) filaments from a 3D pen were measured by solid-phase microextraction (SPME) combined with gas chromatography/mass spectrometry (GC/MS). SPME was investigated using the traditional fiber and Arrow geometries with the DVB/Carbon WR/PDMS sorbent while four different brands of ABS filaments-Amazon Basics, Gizmodork, Mynt 3D, and Novamaker-were used with the 3D pen. Heatmap analysis showed differentiation among these brands based on the liberated VOCs. The nozzle temperature and printing speed were found to affect the number and amount of released VOCs. This study goes a step further and presents for the first time a comparison between 3D pen and a desktop 3D printer based on liberated VOCs. Interestingly, the findings reveal that the 3D pen releases a greater number and amount of VOCs compared to the printer. The amounts of liberated VOCs, as indicated by the corresponding chromatographic peak areas, were found to be 1.4 to 62.6 times higher for the 3D pen compared to the 3D printer when using SPME Arrow.

INTRODUCTION: Neoadjuvant chemotherapy (NAC) is the standard of care for patients undergoing radical cystectomy (RC) for muscle-invasive bladder cancer (MIBC); however, NAC can be associated with significant side effects and morbidity in some patients. NAC may contribute to sarcopenia, obesity, and the combination of the two. Our study examined the effects of NAC on body composition and the association between body composition and adverse events. METHODS: We created a retrospective database of patients with non-metastatic MIBC receiving NAC prior to RC. The change in skeletal muscle index (SMI) and fat mass index (FMI) was calculated using computed tomography (CT) scans done within three months prior to NAC and after the first two cycles. The association between body composition (sarcopenia, obesity, and sarcopenic obesity) and preoperative adverse events was investigated using a multivariable logistic regression. Changes in body composition were calculated using a paired Student's t-test. RESULTS: A total of 70 patients were included in our study. There was a mean decrease in SMI of 2.2±3.2 cm2/m2. Adiposity and FMI were unchanged by NAC. Sarcopenic obesity was found to be associated with adverse events among patients receiving NAC in the multivariable analysis. There was a total of 637 preoperative complications with grades 1-2 and 33 complications with grades 3-5. CONCLUSIONS: Based on our retrospective cohort study, NAC did not affect obesity and FMI, but there was a significant decrease in SMI. Sarcopenic obesity was associated with increased severity of NAC adverse events. As such, the presence of this factor may help predict tolerance of NAC.
RESUMO
Polymeric ionic liquid (PIL) sorbent coatings consisting of polymerizable cations and anions were employed as sorbent coatings in thin film microextraction (TFME) for the extraction of pesticides and cannabinoids. The blades consisted of a thin film of PIL sorbents chemically bonded to vinyltrimethoxysilane-functionalized nitinol sheets. The imidazolium- or ammonium-based PIL sorbents contained aromatic benzyl moieties as well as polar hydroxyl groups or aliphatic functional groups within the chemical structure of the IL monomer. The chemical structure of the IL crosslinkers of the PILs were kept constant across each sorbent, except for the anion, which consisted of either bis[(trifluoromethyl)sulfonyl]imide ([NTf2-]), p-styrenesulfonate ([SS-]), or 3-sulfopropyl acrylate ([SPA-]). Temperature, salt content, and methanol content were optimized as extraction conditions to maximize pesticide-cannabinoid selectivity using Doehlert design of experiments (DOE). Effects of these three factors on selectivity and extraction efficiency are discussed. The optimal extraction conditions consisting of sample temperature (31°C), sodium chloride (30% w/v), and methanol content (0.25% v/v) are compared to initial sorbent screening conditions at a sample temperature of 40°C, 15% (w/v) sodium chloride, and 2.5% (v/v) methanol content. PIL sorbent swelling behavior at different salt and methanol content conditions and its effect on extraction efficiency are hypothesized. Selectivity factors for the sorbents indicated that aromatic moieties within the IL monomer may enhance pesticide-cannabinoid selectivity under optimized conditions, but the extraction efficiency of pesticides that are known to coelute with cannabinoids in the chromatographic separation may be enhanced by employing sorbent coatings with [SPA-] anions.

A 28-day Prostate Cancer-Patient Empowerment Program (PC-PEP) developed through patient engagement was successful at promoting mental and physical health. Thirty prostate cancer patients from Halifax, Canada participated in the 28-day PC-PEP intervention in early 2019. PC-PEP encompassed daily patient education and empowerment videos, prescribed physical activities (including pelvic floor exercises), a mostly plant-based diet, stress reduction techniques, intimacy education, social connection, and support. Quantitative exit surveys and semi-structured interviews (conducted in focus groups of ten) were used to assess perceived factors that facilitated or impeded adherence to the program. The program received high praise from the patients and was deemed extremely useful by the participating men, who rated it 9 out of 10. Patients expressed that the multifaceted, online, home-based nature of the program helped them adhere to it better than they would have had to a single or less comprehensive intervention. Feedback from the participants indicated that the program, when viewed as a whole, was perceived as greater than the sum of its individual parts. Furthermore, the program addressed various issues, including emotional vulnerability and distress, physical fitness, urinary incontinence, challenges in expressing emotions, perceived lack of control over healthcare decisions, emotional fragility, and hesitancy to discuss prostate cancer-related matters in social settings. Patients highly (9.6/10) endorsed integrating the program into the standard care regimen from the very beginning of diagnosis. However, challenges such as work commitments were noted. Patients' high endorsement of PC-PEP suggests that its implementation into the standard of care from day one of diagnosis may be warranted.

Surface silanols (Si-OH) play a vital role on fused silica surfaces in chromatography. Here, we used an atmospheric-pressure, gas-phase reactor to modify the inner surface of a gas chromatography, fused silica capillary column (0.53 mm ID) with a small, reactive silane (tris(dimethylamino)methylsilane, TDMAMS). The deposition of TDMAMS on planar witness samples around the capillary was confirmed with X-ray photoelectron spectroscopy (XPS), ex situ spectroscopic ellipsometry (SE), and wetting. The number of surface silanols on unmodified and TDMAMS-modified native oxide-terminated silicon were quantified by tagging with dimethylzinc (DMZ) via atomic layer deposition (ALD) and counting the resulting zinc atoms with high sensitivity-low energy ion scattering (HS-LEIS). A bare, clean native oxide - terminated silicon wafer has 3.66 OH/nm2, which agrees with density functional theory (DFT) calculations from the literature. After TDMAMS modification of native oxide-terminated silicon, the number of surface silanols decreases by a factor of ca. 10 (to 0.31 OH/nm2). Intermediate surface testing (IST) was used to characterize the surface activities of functionalized capillaries. It suggested a significant deactivation/passivation of the capillary with some surface silanols remaining; the modified capillary shows significant deactivation compared to the native/unmodified fused silica tubing. We believe that this methodology for determining the number of residual silanols on silanized fused silica will be enabling for chromatography.

OBJECTIVE: Lumbar spine decompression surgery, in the form of laminectomy or discectomy, is known to be effective in improving symptoms of radiculopathy and neurogenic claudication. However, it is less clear how it impacts coexisting low-back pain (LBP). The aim of this study was to quantify the change in LBP after lumbar decompression. METHODS: This study analyzed data from the British Spine Registry on patients who underwent lumbar decompression surgery. LBP severity was assessed using the visual analog scale (VAS), and the primary outcome was the change in VAS score at 1 year, with secondary outcomes measuring the change in score at 6 weeks, 6 months, and 2 years. The minimal clinically important difference (MCID) was defined as a 30% reduction in pain. RESULTS: Of the 25,349 patients included in the study, 92.2% reported significant back pain at baseline. Of the entire cohort, 12,951 (55.4%) patients had follow-up data for 6 weeks, 9066 (38.8%) for 6 months, 7926 (33.9%) for 1 year, and 5517 (23.6%) for 2 years; 17,304 (68.3%) patients had follow-up data for at least one time point. Sixty-two percent of patients attained the MCID (VAS score ≥ 30%) in back pain reduction, with 51% reporting a substantial improvement (VAS score ≥ 50%). This improvement was observed by 6 weeks postoperation and was mostly maintained at 2 years. Patients with back pain predominance were more likely to attain the MCID compared with those with leg pain predominance (63.6% vs 60.1%; OR 1.16, 95% CI 1.02-1.34; p = 0.0291). Severity of baseline back pain did not reduce the proportion attaining the MCID. CONCLUSIONS: Regardless of pain presentation, LBP improves in approximately 62% of patients who undergo lumbar decompressive surgery, with 51% experiencing substantial improvement. Patients undergoing lumbar decompression can be advised on the chance of a meaningful improvement in back pain postsurgery.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic forced many changes. In our unit, there was a significant shift from traditional anesthesia (TA) which included general or regional anesthesia, to Wide-Awake Local Anesthesia No Tourniquet (WALANT) for the treatment of flexor tendon injuries. Zones I and II injuries have always been a challenge. The primary aim of this study is to compare the 12-week range of motion (ROM) flexor tendon repair outcomes between the TA group and wide-awake (WA) group patients. The secondary aim is to compare the complications and the follow-up rate between the two groups. METHODS: All patients who underwent a primary finger flexor tendon repair in zone I or II without tendon graft for closed avulsions or open lacerations between April 2020 and March 2021 were included in the study. Electronic medical records were reviewed to record demographics, follow-up, ROM outcomes and complications. RESULTS: Forty-four patients with 49 injured fingers were in the WA group, and 24 patients with 37 injured fingers were in the TA group. A complete follow-up with 12-week ROM outcomes was available for 15 patients with 16 injured fingers in the WA group and nine patients with 13 injured fingers in the TA group. Excellent to good outcomes in the WA group were reported in 56% of the cases versus 31% in the TA group, although the difference was not statistically significant. There were similar complications in both groups, with an overall rupture rate of 11.6%, a tenolysis rate of 3.5% and a reoperation rate of 9.3%. Complete 12-week follow-up was completed by 41% of patients overall after taking tendon ruptures into account. CONCLUSIONS: This is one of the first studies comparing zones I and II flexor tendon ROM outcomes between WA anesthesia and TA. Overall, there was a trend toward superior ROM outcomes in the WA group, with similar complication rates in both groups. The difference between ROM outcomes was not statistically significant and the small sample size undermined the strength of the study. To provide stronger evidence, better-designed prospective studies are suggested that would compare WA techniques with TA techniques.
RESUMO
Background: Debate regarding effectiveness of surgical modalities contributes to a lack of consensus of decision making for surgical interventions. Furthermore, data regarding cost effectiveness, surgical operative time, resources, patient hospital stay and recovery is limited, particularly in the medium term for degenerative lumbar spondylolisthesis. The objective was to compare clinical outcomes following different fixation interventions treating degenerative lumbar spondylolisthesis. Methods: A retrospective cohort study using the British Spine Registry (BSR) of 1,838 patients aged ≥18 years. Five hundred and five patients undergoing posterior lumbar interbody fusion (PLIF) and 1,333 undergoing transforaminal lumbar interbody fusion (TLIF) with 6 months follow-up, were compared. Demographics, Oswestry Disability Index (ODI), Numerical Rating Scale (NRS) [back and leg], quality of life, complications and cost effectiveness were analysed. Results: NRS (back and leg) demonstrated a statistically significant difference favouring TLIF at 6 months (P=0.04) and (P<0.05) respectively. There was no difference in ODI improvement at 6 months between PLIF and TLIF (P=0.620), but there was a statistically significant difference in ODI scores preoperatively between PLIF and TLIF (P<0.001). EQ-5D-5L-Health VAS (P=0.136) and EQ-5D-5L (P=0.655) did not show a statistically significant difference in improvement between PLIF and TLIF. Dural tear was the most common complication and was higher in the PLIF group (5.7%) but not statistically significant. Estimated blood loss was greater for PLIF (P=0.041). Implant cost (P<0.001) was higher for TLIF whereas theatre time was higher for PLIF (P=0.031). Conclusions: Both PLIF and TLIF result in clinically significant improvements in ODI, NRS back pain and NRS leg pain, with superiority of TLIF for improvements in back and leg pain. Surgeons appeared to use ODI preoperatively to decide intervention with comparable improvements for both approaches. Average theatre time and blood loss volume was higher for PLIF. Factors like implant costs and costs of consumables were higher for TLIF. Costs merit further evaluation.
RESUMO
A previously reported autoreactive antigen, termed the X-idiotype, isolated from a unique cell population in Type 1 diabetes (T1D) patients, was found to stimulate their CD4+ T cells. This antigen was previously determined to bind more favorably than insulin and its mimic (insulin superagonist) to HLA-DQ8, supporting its strong role in CD4+ T cell activation. In this work, we probed HLA-X-idiotype-TCR binding and designed enhanced-reactive pHLA-TCR antigens using an in silico mutagenesis approach which we functionally validated by cell proliferation assays and flow cytometry. From a combination of single, double, and swap mutations, we identified antigen-binding sites p4 and p6 as potential mutation sites for HLA binding affinity enhancement. Site p6 is revealed to favor smaller but more hydrophobic residues than the native tyrosine, such as valine (Y6V) and isoleucine (Y6I), indicating a steric mechanism in binding affinity improvement. Meanwhile, site p4 methionine mutation to hydrophobic residues isoleucine (M4I) or leucine (M4L) modestly increases HLA binding affinity. Select p6 mutations to cysteine (Y6C) or isoleucine (Y6I) exhibit favorable TCR binding affinities, while a swap p5-p6 tyrosine-valine double mutant (V5Y_Y6V) and a p6-p7 glutamine-glutamine double mutant (Y6Q_Y7Q) exhibit enhanced HLA binding affinity but weakened TCR affinity. This work holds relevance to potential T1D antigen-based vaccine design and optimization.

Three-dimensional (3D) printers have gained tremendous popularity and are being widely used in offices, laboratories, and private homes. Fused deposition modeling (FDM) is among the most commonly used mechanisms by desktop 3D printers in indoor settings and relies on the extrusion and deposition of heated thermoplastic filaments, resulting in the liberation of volatile organic compounds (VOCs). With the growing use of 3D printers, concerns regarding human health have risen as the exposure to VOCs may cause adverse health effects. Therefore, it is important to monitor VOC liberation during printing and to correlate it to filament composition. In this study, VOCs liberated with a desktop printer were measured by solid-phase microextraction (SPME) combined with gas chromatography/mass spectrometry (GC/MS). SPME fibers featuring sorbent coatings of varied polarity were chosen for the extraction of VOCs liberated from acrylonitrile butadiene styrene (ABS), tough polylactic acid, and copolyester+ (CPE+) filaments. It was found that for all three filaments tested, longer print times resulted in a greater number of extracted VOCs. The ABS filament liberated the most VOCs while the CPE+ filaments liberated the fewest VOCs. Through the use of hierarchical cluster analysis and principal component analysis, filaments as well as fibers could be differentiated based on the liberated VOCs. This study demonstrates that SPME is a promising tool to sample and extract VOCs liberated during 3D printing under non-equilibrium conditions and can be used to aid in tentative identification of the VOCs when coupled to gas chromatography-mass spectrometry.

INTRODUCTION: Radical cystectomy (RC) is associated with high rates of morbidity, prolonged hospital stay, and increased opioid use for postoperative pain management; however, the relationship between postoperative opioid use and length of stay (LOS ) remains uncharacterized. This study serves to investigate the association between postoperative opioid use and length of hospital stay after RC. The relationship between patient and surgical factors on LOS was also characterized. METHODS: We retrospectively reviewed all patients between 2009 and 2019 who underwent RC at our institution. Patient and perioperative variables were analyzed to determine the relationship between postoperative opioid use and LOS using multivariable linear regression analysis. RESULTS: We identified 240 patients for study inclusion with a median age of 70.0 years. Median LOS was 10.0 days, with median daily mg morphine equivalent use of 57.5 for patients. Daily mg morphine equivalent use was significantly associated with an increased LOS, as were previous pelvic radiation, postoperative ileus, and higher Clavien-Dindo grade complication during admission (all p<0.05). Median LOS increased by one day for each increase of 13.2 daily mg morphine equivalents received. CONCLUSIONS: Increased daily opioid use was associated with increased length of hospital stay after RC. Non-opioid-based pain management approaches may be effective in reducing LOS after RC.
RESUMO
BACKGROUND: Although survival rates for newly diagnosed prostate cancer patients are very high, most of them will likely suffer significant treatment-related side effects, depression, or anxiety, affecting their quality of life. OBJECTIVE: The aim of this study was to examine the effects of a 6-mo online home-based physical, mental, and social support intervention, the Prostate Cancer Patient Empowerment Program (PC-PEP), on preventing psychological distress among men undergoing curative prostate cancer treatment. DESIGN, SETTING, AND PARTICIPANTS: In a crossover randomized clinical trial of 128 men aged 50-82 yr scheduled for curative prostate cancer surgery or radiotherapy (± hormone treatment), 66 received the 6-mo PC-PEP intervention and 62 were randomized to a waitlist-control arm and received the standard of care for 6 mo, and then PC-PEP to the end of the year. The PC-PEP intervention consisted of daily e-mails with video instructions providing education, patient activation, and empowerment on healthy living including physical and mental health, dietary recommendations, social support, physical and pelvic floor fitness, stress reduction using a biofeedback device, social connection and intimacy, and social support. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary outcome was nonspecific psychological distress (clinical cutoff ≥20) measured at baseline, and at 6 and 12 mo using the Kessler Psychological Distress Scale (K10). RESULTS AND LIMITATIONS: At 6 mo, patients in the waitlist-control group had 3.59 (95% confidence interval: 1.12-11.51) times higher odds for nonspecific psychological distress and need for psychological treatment than men who received the PC-PEP intervention. At 12 mo, the wait-list control group that received the intervention at 6 mo had higher psychological distress than the early group. CONCLUSIONS: PC-PEP delivered early following diagnosis significantly prevented the burden of psychological distress in men undergoing curative prostate cancer treatment compared with standard of care, or late (6 mo later) intervention. PATIENT SUMMARY: In this report, we looked at the effectiveness of a program (Prostate Cancer Patient Empowerment Program: PC-PEP) developed with patients' engagement on the mental distress of patients awaiting curative treatment for their prostate cancer. The PC-PEP program lasted for 6 mo, and it prescribed, described, and demonstrated daily aerobic and strength training, kegels (pelvic floor training to help with urinary and sexual function), dietary changes that have been shown to be helpful in the prevention of prostate cancer and prostate cancer progression, stress reduction using a biofeedback device, as well as social and emotional support. All patients in the PC-PEP program were invited to a monthly video conference with the leads of the program who appeared in the 6 mo of daily videos prescribing the activities the patients were asked to watch and follow. The leads were a prostate cancer oncologist and a scientist in prostate cancer quality of life research. Half of the patients in this study received PC-PEP daily for the first 6 mo and were re-assessed at the end of the year. The other half received standard of care for 6 month and then received the intervention to the end of the year. The results of the study show that, at 6 mo, this intervention was effective at reducing the mental distress that accompanies a prostate cancer diagnosis and treatment compared with the standard of care. Mental distress was significantly reduced when the intervention was received early, compared with that received late (6 mo after scheduled curative treatment). We conclude that multi-faceted patient education and empowerment programming of this kind that is developed with patient engagement from the start is crucial to the care of patients diagnosed with prostate cancer and should be implemented in the standard of care. While treatment for prostate cancer is highly successful, side effects that accompany most treatments significantly affect the quality of life of patients. Here, we describe PC-PEP, a patient education and activation program that is cost effective, highly enforced by patients, and successful at reducing the impact of prostate cancer active treatment-related side effects on their psychological state. To learn more about this project, please visit www.pcpep.org. The program is now being tested in a phase 4 implementation trial throughout Canada and internationally (New Zealand), and is being expanded and tested for other types of cancer.

BACKGROUND: Spontaneous spinal epidural hematoma (SSEH) is a rare pathology, which carries a significant morbidity. OBJECTIVE: To review our institutional experience of surgically managed patients with SSEH, seeking to better understand clinical prognostic factors related to postoperative outcomes and thereby improve counseling of patients before treatment. METHODS: All patients who underwent surgical management of SSEH between September 2011 and 2021. Baseline and postoperative clinical and radiological characteristics are presented, including the American Spinal Injury Association grade (ASIA). Statistical analyses were performed using Stata 13.1. RESULTS: Eighteen patients were identified in total (11 male patients and 7 female patients) with a median age of 59.5 (range 3-83) years. The most common spinal region affected was cervicothoracic (33.3%). Limb weakness (94.4%) and urinary dysfunction (83.3%) represented the most common presenting symptoms. Preoperatively, the presence of spinal cord edema on imaging was associated with worse preoperative Medical Research Council (MRC) grade ( P = .033), female sex was associated with preserved saddle sensation ( P = .04), and patients receiving antiplatelet medication were associated with a higher risk of preoperative axial back pain ( P = .005). Higher postoperative MRC grade was associated with higher preoperative ASIA ( P = .012) and MRC grade ( P = .005), and preservation of saddle sensation ( P = .018). Postoperative improvements in axial back pain were associated with higher preoperative ASIA grade ( P = .035) and anticoagulation treatment ( P = .029). CONCLUSION: Neurosurgical intervention for SSEH yields positive outcomes and benefits patients. Patients with higher preoperative ASIA, MRC grade, and those presenting with preserved saddle sensation may experience further improved clinical outcomes after intervention.

CONTEXT: Although the return to sports during COVID-19 has been associated with improvements in mental health and quality of life (QOL), whether these benefits are primarily due to increases in physical activity (PA) is unknown. OBJECTIVE: To determine whether PA increases were responsible for the improvements in mental health and QOL among adolescents who returned to sport during the COVID-19 pandemic. DESIGN: Cross-sectional study. SETTING: Wisconsin secondary schools. PATIENTS OR OTHER PARTICIPANTS: A total of 559 adolescent athletes (age = 15.7 + 1.2 years, females = 43.6%) from 44 schools completed a survey in October 2020. MAIN OUTCOME MEASURE(S): Demographic information, whether they had returned to sport participation, school instruction type, anxiety (Generalized Anxiety Disorder-7), depression (Patient Health Questionnaire-9), QOL (Pediatric Quality of Life Inventory 4.0), and PA (Hospital for Special Surgery Pediatric Functional Activity Brief Scale). Mediation analysis was used to assess whether the relationships between sport status and anxiety, depression, and QOL were mediated by PA. RESULTS: At the time of the study, 171 (31%) had returned to play and 388 (69%) had not. Athletes who had returned to play had less anxiety (3.6 ± 0.4 versus 8.2 ± 0.6, P < .001) and depression (4.2 ± 0.4 versus 7.3 ± 0.6, P < .001) and higher QOL (88.1 ± 1.0 versus 80.2 ± 1.4, P < .001) and more PA (24.0 ± 0.5 versus 16.3 ± 0.7, P < .001). Physical activity explained a significant, but small, proportion of the difference in depression (22.1%, P = .02) and QOL (16.0%, P = .048) but not anxiety (6.6%, P = .20) between athletes who had and those who had not returned to play. CONCLUSIONS: Increased PA was responsible for only a small portion of the improvements in depression and QOL among athletes who returned to sports. This suggests that most of the mental health benefits of sport participation for adolescents during the COVID-19 pandemic were independent of the benefits of increased PA.

PURPOSE: To evaluate the changes in mental health, quality of life (QOL) and physical activity (PA) among adolescent athletes during the COVID-19 pandemic as organised sports resumed. METHODS: Adolescent athletes completed surveys including demographic and sport participation information, 7-item Generalized Anxiety Disorder, 9-item Patient Health Questionnaire, Pediatric Quality of Life Inventory and the Hospital for Special Surgery Pediatric Functional Activity Brief Scale in May 2020 following COVID-19-related sport cancellations (Spring20) and after returning to sports in May 2021 (Spring21). The groups were balanced by inverse propensity score weighting and compared using analysis of variance models and ordinal regression models. RESULTS: 17 421 participants were included (Spring20=13 002; Spring21=4419; 16.2±1.2 years; 53% female). Anxiety was significantly lower (better) in Spring21 (Spring20=7.0, 95% CI 6.9 to 7.1; Spring21=4.9, 95% CI 4.8 to 5.0, p<0.001), as was the prevalence of moderate to severe anxiety (Spring20=29.4%, Spring21=17.1%, p<0.001). Depression was significantly improved in Spring21 (Spring20=7.6, 95% CI 7.5 to 7.7; Spring21=4.6, 95% CI 4.5 to 4.8, p<0.001), as was the prevalence of moderate to severe depression (Spring20=32.2%, Spring21=15.4%, p<0.001). Athletes in Spring21 reported higher QOL (Spring20=79.6, 95% CI 79.3 to 79.9; Spring21=84.7, 95% CI 84.4 to 85.0, p<0.001) and increased levels of PA (Spring20=13.8, 95% CI 13.6 to 13.9; Spring21=22.7, 95% CI 22.6 to 22.9, p<0.001). CONCLUSION: Early COVID-19 sports restrictions were associated with worsening mental health in adolescents. In 2021, after returning to sports, athletes reported significant improvements in mental health, QOL and PA, although mental health adversities remain an important priority.

CONTEXT: Sport cancellations early in the COVID-19 pandemic had a significant negative effect on the health of US adolescents. The effect of restarting sports during the pandemic has not been described. OBJECTIVE: To identify the effect of sport participation on the health of adolescents before and during the COVID-19 pandemic. DESIGN: Cross-sectional study. SETTING: Sample recruited via social media. PATIENTS OR OTHER PARTICIPANTS: Wisconsin adolescent athletes. MAIN OUTCOME MEASURE(S): Participants provided information regarding their age, sex, and sport(s) involvement and completed the Patient Health Questionnaire-9 Item to assess depression symptoms, the Hospital for Special Surgery Pediatric Functional Activity Brief Scale to measure physical activity, and the Pediatric Quality of Life Inventory 4.0 to measure quality of life (QoL). Data were collected in spring 2021 (Spring21; n = 1906, age = 16.0 ± 1.2 years, females = 48.8%), when interscholastic sports had fully resumed, and were compared with similar cohorts of adolescent athletes at 2 time points: (1) spring 2020 (Spring20; n = 3243, age = 16.2 ± 1.2 years, females = 57.9%) when sports were cancelled and (2) 2016-2018 (PreCOVID-19) before the pandemic (n = 5231, age = 15.7 ± 1.1 years, females = 65.0%). Comparisons were conducted via analysis-of-variance models and ordinal regressions with age and sex as covariates. RESULTS: The prevalence of moderate to severe depression was lower in Spring21 than in Spring20 but higher than in PreCOVID-19 (PreCOVID-19 = 5.3%, Spring20 = 37.8%, Spring21 = 22.8%; P < .001). Physical activity scores (mean [95% CI]) were higher in Spring21 than in Spring20 but lower than in PreCOVID-19 (PreCOVID-19 = 23.1 [22.7, 23.5], Spring20 = 13.5 [13.3, 13.7], Spring21 = 21.9 [21.6, 22.2]). Similarly, QoL scores were higher in Spring21 than in Spring20 but lower than in PreCOVID-19 (PreCOVID-19 = 92.8 [92.5, 93.1], Spring20 = 80.7 [80.3, 81.1], Spring21 = 84.3 [83.8, 84.8]). CONCLUSIONS: Although sports have restarted, clinicians should be aware that physical activity, mental health, and QoL are still significantly affected in adolescent athletes by the ongoing pandemic.

INTRODUCTION: Routine measurements of serum hemoglobin (sHgb) are common after abdominal surgery; however, prolonged measurements may be associated with patient anxiety, increased costs, and longer hospitalization without clinical benefit. The objective of this study was to determine the utility of routine sHgb measurements after radical cystectomy (RC) and factors associated with transfusion of packed red blood cell (pRB C) beyond postoperative day (POD ) 2. METHODS: We retrospectively reviewed patients who underwent RC between 2009 and 2019 at a single academic tertiary care center. The number of sHgb measurements for each patient was examined and pRB C transfusion rates were calculated. Multivariable logistic regression was used to determine factors associated with transfusion beyond POD 2. RESULTS: The median number of sHgb measurements per patient during admission was nine (interquartile range [IQR] 7, 25). Overall, 69/240 (28.7%) patients received a postoperative transfusion, including 46/240 (19.2%) patients receiving a transfusion beyond POD 2. Among patients with a sHgb ≥100 g/L on POD 2, 7/85 (8.2%) went on to receive a transfusion beyond this day compared with 39/155 (25.2%) patients with sHgb <100 g/L. On multivariable analysis, risk factors associated with pRB C transfusion beyond POD 2 included older age, lower sHgb on POD 2, and longer length of stay in hospital. CONCLUSIONS: Transfusion of pRB Cs beyond POD 2 was found to be common; however, patients with sHgb ≥100 g/L on POD 2 were at low risk of requiring subsequent transfusion. Discontinuing further routine sHgb checks in these patients may serve to decrease patient anxiety, healthcare costs, and delays in hospital discharge.
