RESUMO
PURPOSE: The aim of this study is to determine the effect of forcing and filling the electron density (ED) to 1.0 of the planning target volume (PTV) overdose distribution in lung SBRT treatment leading to shortening patient treatment time and increasing patient comfort by reducing MU/fraction due to ED manipulation effect. METHODS: In this study, 36 lung SBRT plans of 12 suitable patients who prescribed a total dose of 50 Gy in five fractions were generated with Monaco v.5.10 TPS using the Monte Carlo (MC) algorithm and volumetric modulated arc therapy (VMAT) technique by PTV ED values forcing as well as filling to 1.0 and comparatively assessed. The first group of plans was created by using the patient's original ED, second and third groups of plans were reoptimized by forcing and filling the ED of PTV to 1.0, respectively, therefore acquiring a new dose distribution which lead to comparatively assessment the effects of changes in ED on PTV and OAR doses. RESULTS: Assessment of treatment plans revealed that mean MU/fx numbers were decreased by 76% and 75.25% between Groups 1 and 2, Groups 1 and 3, respectively. The number of segments was also reduced in Group 1 by up to 15% compared with Groups 2 and 3. Maximum HI and CI differences for PTV between Groups 1 and 2 were less than 1% and Groups 1 and 3 were 1.5% which indicates all 3 group plans were comparable in terms of dose distribution within PTV. CONCLUSIONS: Forcing and filling the ED of PTV to 1.0 strategy has provided reduced a number of segments and MU/fx without a significant change in PTV mean and maximum doses, thereby decreasing treatment time and patient discomfort during treatment. This process should be considered in line of a potential number of patients as well as prescribed dose and MU/fx numbers.
RESUMO
Background The transition of junior doctors into working in the emergency department (ED) in the United Kingdom often poses challenges in adapting to new hospital systems and protocols. To address this issue at Queen Elizabeth Hospital, King's Lynn (QEHKL), a quality improvement project (QIP) was undertaken to develop an electronic ED handbook with the primary aim of enhancing the confidence and knowledge of newly appointed doctors during their ED rotation. This electronic handbook serves as a comprehensive repository for vital medical protocols, guidelines, and trust referral pathways, offering an easily accessible resource for junior doctors. Objectives The primary objective of this study was to determine whether there was an improvement in the confidence and knowledge of ED junior doctors following the introduction of the Electronic ED Handbook. The secondary objectives were to determine whether introducing the ED Handbook increased the overall satisfaction rating of the content of the ED Junior Doctor Induction program and assess the level of recommendation for the ED Handbook among the doctors for inclusion in future ED inductions. Method The QIP was designed using the Model for Improvement framework, Plan, Do, Study, Act (PSDA). The aims were designed to be Specific, Measurable, Achievable, Relevant, and Time-bound (SMART). Pre- and post-intervention surveys were conducted for comparison before and after the ED Handbook was introduced. Results Regarding the confidence of junior doctors to proceed into their new roles, the responses of "quite confident" or "very confident" increased from 77.8% (before) to 100% (after the ED Handbook introduction). One hundred percent of the responders found the ED Handbook to be either "very useful" or "extremely useful" in increasing their confidence and knowledge in the first month of their ED rotation. The satisfaction rating of "excellent" for the content of the ED Junior Doctor Induction program increased from 55.5% to 66.7%. One hundred percent of the responders recommended the inclusion of the ED Handbook for future inductions. Conclusion and recommendations Comparing the results from the pre- and post-intervention surveys shows a significant improvement in the confidence and knowledge of ED junior doctors following the introduction of the Electronic ED Handbook. The handbook was formally endorsed by the ED clinical governance team as an integral component of the ED induction process, aiding junior doctors in making a seamless transition into their new roles in emergency medicine. This study emphasizes the importance of utilizing digital resources to improve the confidence and knowledge of junior doctors and recommends the continued use of the handbook in future induction programs.
RESUMO
Background: Erectile dysfunction (ED) is an independent predictor for cardiovascular diseases (CVD). The prevalence increases with age, but little is known about the relationship between handgrip strength (HGS) and ED, especially among men with a high risk of CVD. This study aimed to determine the prevalence of ED among men aged ≥40 years with metabolic syndrome (MetS) and its association with HGS. Materials and Methods: A cross-sectional study at an institutional primary care clinic in Malaysia was conducted between June 2021 and October 2021. HGS and erectile function were assessed using a hand dynamometer and International Index of Erectile Function (IIEF-5) questionnaire, respectively. Multiple logistic regression analyses were performed to determine the association between sociodemographics, clinical characteristics, and HGS with ED. Results: A total of 334 participants were recruited. The prevalence of ED was 79% (95% confidence interval [CI]: 0.75-0.84). ED was associated with elderly aged ≥60 years (odds ratio [OR] 3.27, 95%CI: 1.60-6.69), low HGS (OR 15.34, 95%CI: 5.64-41.81) and high total cholesterol (OR 0.36, 95%CI: 0.16-0.78). Conclusion: In conclusion, age above 60 years and those with low HGS are at higher risk of ED. Thus, robust screening of ED among men with MetS and improving muscle strength and physical fitness may be warranted.
RESUMO
Background: Having a spicy diet and smoking habit may be important factors causing erectile dysfunction (ED). The aim of this study is to investigate the impact of spicy diet and smoking habits on the risk of ED in men, with a focus on the interaction between these lifestyle factors. Methods: Our investigation was conducted as a retrospective analysis spanning from June 2017 to June 2023. Participants underwent interviews utilizing the Structured Interview on Erectile Dysfunction (SIEDY) to evaluate the degree of pathological factors. The International Index of Erectile Function-5 (IIEF-5) was employed as a metric for assessing ED. Additionally, the subjects were comprehensively questioned about their smoking history and dietary preferences, which included an inquiry into how often they consumed spicy meals. Results: Our research involved 373 participants, with 67.6% being individuals with ED. Among the participants, 50.7% were non-smokers and 49.3% were smokers, totaling 188 and 185, respectively. There was no significant difference in the spicy food frequency consumption among smokers with ED. However, non-smokers who consumed spicy food more frequently experienced more severe ED (P=0.02). ED patients showed significant differences in body mass index (BMI), blood glucose and testosterone, which were linked to vascular damage (P=0.03, P=0.02, P=0.04, respectively). Additionally, non-smokers who consumed more spicy food had higher scores on the SIEDY 2 scale, indicating marital factors (P=0.004). In non-smoking participant, a high spicy ratio indicated an even higher risk of ED [odds ratio 2.58, 95% confidence interval: 1.27-5.26; P=0.008], while there was no significant impact on ED in smoking participants (data not shown). Conclusions: This retrospective study suggests that a considerable consumption of spicy foods is independently correlated with an elevated risk of ED, particularly among non-smoking men.
RESUMO
Objectives: During the coronavirus disease 2019 (COVID-19) pandemic surge, alternate care sites (ACS) such as the waiting room or hospital lobby were created amongst hospitals nationwide to help alleviate emergency department (ED) overflow. Despite the end of the pandemic surge, many of these ACS remain functional given the burden of prolonged ED wait times, with providers now utilizing the waiting room or ACS to initiate care. Therefore, the objective of this study is to evaluate if initiating patient care in ACS helps to decrease time to disposition. Methods: Retrospective data were collected on 61,869 patient encounters presenting to an academic medical center ED. Patients with an emergency severity index (ESI) of 1 were excluded. The "pre-ACS" or control data consisted of 38,625 patient encounters from September 30, 2018 to October 1, 2019, prior to the development of ACS, in which the patient was seen by a physician after they were brought to an assigned ED room. The "post-ACS" study cohort consisted of 23,244 patient encounters from September 30, 2022 to October 1, 2023, after the initiation of ACS, during which patients were initially seen by a provider in an ACS. ACS at this institution included the three following areas: waiting room, ambulance waiting area, and a newly constructed ACS that was built next to the ED entrance on the first floor of the hospital. The newly constructed ACS consisted of 16 care spaces each containing an upright exam chair with dividers between each care space. Door-to-disposition time (DTD) was calculated by identifying the time when the patient entered the ED and the time when disposition was decided (admission requested or patient discharged). Using regression analysis, we compared the two data sets to determine significant differences among DTD time. Results: The largest proportion of encounters were among ESI 3 patients, that is, 56.1%. There was a significant increase in median DTD for ESI 2 and 3 patients who were seen initially in an ACS compared to those who were not seen until they were in an assigned ER room. Specifically, there was a median increase of 40.9 min for ESI 2 patients and 18.8 min for ESI 3 patients who were seen initially in an ACS (p < 0.001). There was a 29-min decrease in median DTD for ESI 5 patients who were seen in ACS (p = 0.09). Conclusions: Initiating patient care earlier in ACS did not appear to decrease DTD time for patients in the ED. Overall, the benefits of early initiation of care likely lie elsewhere within patient care and the ED throughput process.
RESUMO
BACKGROUND: As the Medicare population continues to grow, financial pressure is placed upon hospitals, physicians, and other providers as the payer mix has an increasing proportion of Medicare patients. OBJECTIVE: The purpose of this study was to further the understanding of reimbursement trends surrounding the five levels of emergency department (ED) examinations (CPT codes 99281-99285) from 2010 to 2018 and determine how they have changed with respect to each procedure. METHODS: CPT codes were filtered into the 2010 and 2018 Physician/Supplier Procedure Summaries from the Centers for Medicare and Medicaid Services' website to gather data on emergency physician submissions and Medicare denials and payments. RESULTS: In 2010, 15,669,196 ED examinations were submitted to Medicare for $7,628,693,382 while in 2018, 16,432,184 ED examinations were submitted for $14,522,456,383. Despite an increase of $397/submission made by emergency physicians, Medicare paid 20.5% of the submitted charges in 2010 for ED examinations and 11.9% in 2018. The denial rate in 2018 was highest for level I ED examinations (11.3%), and the lowest for level V examinations (5.1%). The utilization of level V ED examinations increased 22.3% from 2010 to 2018, while the utilization of the others decreased. Of the five levels of ED examinations, only the level I examination did not exhibit a decrease. CONCLUSIONS: From 2010 to 2018, emergency physicians charged a higher amount for ED examinations, yet Medicare reimbursement accounted for a smaller proportion of these charges, resulting in less payment per submission for the four most common levels. Downward trends in Medicare reimbursement may place financial burdens that could potentially hamper healthcare outcomes.
RESUMO
BACKGROUND: Surgical penile prosthesis implantation (PPI) procedures have only recently been introduced to mainland China, with the overall number of such procedures having been conducted to date remaining relatively low. Accordingly, relatively little remains known with respect to the annual trends in PPI. Accordingly, this study was developed with the goal of clarifying these trends across different hospitals in mainland China, while also providing a single-center overview of post-PPI patient outcomes. RESULTS: To identify males in mainland China who had undergone PPI, a retrospective review of data from January 2019 - October 2023 was conducted. This approach revealed an increase in the total PPI caseload from 120 in 2019 to 413 within the first 10 months of 2023. Over this same interval, the number of surgeons performing PPI rose from 33 to 74. A retrospective review of the 112 patients who had undergone PPI at Shanghai General Hospital from 2019-2023 revealed that these patients had a median age of 39 [27-63] years, and PPI treatment led to a significant increase in median International Index of Erectile Function-5 (IIEF-5) scores from a baseline value of 10.23 ± 1.26 to a post-treatment value of 22.6 ± 2.73. The underlying causes of erectile dysfunction for these patients included vasculogenic factors (58/112; 51.8%), diabetes mellitus (21/112; 18.8%), and injuries to the spinal cord or pelvis (14/112; 12.5%). The overall rates of satisfaction with the PPI reported by patients and their partners were 93.0% and 90.4%, respectively, and the 3-year PPI survival rate for this cohort was 87%. CONCLUSION: These data highlight a rising trend in the number of PPI being performed in China, with these steadily increasing rates since 2019 emphasizing the increasingly high levels of acceptance of this procedure by patients and clinicians as a means of treating erectile dysfunction. However, the expertise is restricted to a small number of surgeons. Even so, it is a safe and efficacious approach to managing severe erectile dysfunction for patients in China, and when performed by experienced surgeons based on standardized protocols, low complication rates can be achieved while providing patients and their sexual partners with high levels of satisfaction.
RéSUMé: CONTEXTE: Les procédures chirurgicales d'implantation de prothèses péniennes (IPP) n'ont été que récemment introduites en Chine continentale, le nombre total de procédures de ce type ayant été effectuées à ce jour restant relativement faible. On ne sait donc encore que relativement peu de choses sur les tendances annuelles de l'IPP. La présente étude a été développée dans le but de clarifier ces tendances dans différents hôpitaux de Chine continentale, tout en fournissant une vue d'ensemble des résultats des patients post-IPP dans un seul centre. RéSULTATS: Afin d'identifier les hommes de Chine continentale qui avaient subi un IPP, une recherche rétrospective des données a été effectuée de janvier 2019 à octobre 2023. Cette approche a révélé une augmentation du nombre total de cas d'IPP de 120 en 2019 à 413 au cours des 10 premiers mois de 2023. Au cours de cette même période, le nombre de chirurgiens pratiquant des IPP est passé de 33 à 74. L'étude rétrospective des 112 patients qui avaient subi un IPP à l'hôpital général de Shanghai de 2019 à 2023 a révélé qu' ils avaient un âge médian de 39 [2763] ans, et que le traitement par IPP a entraîné une augmentation significative des scores médians de l'indice international de la fonction érectile-5, qui sont passés d'une valeur de base de 10,2 ± 1,3 à une valeur post-traitement de 22,6 ± 2,7. Les causes sous-jacentes de la dysfonction érectile chez ces patients comprenaient des facteurs vasculogéniques (58/112; 51,8%), un diabète (21/112; 18,8%) et des lésions de la moelle épinière ou du bassin (14/112; 12,5%). Les taux globaux de satisfaction à l'égard de l'IPP, rapportés par les patients et leurs partenaires, étaient respectivement de 93,0% et 90,4%, et le taux de survie à 3 ans de l'IPP dans cette cohorte était de 87%. CONCLUSION: Ces données mettent en évidence une tendance à la hausse du nombre d'IPP pratiquées en Chine; ces taux en constante augmentation depuis 2019 soulignent les niveaux de plus en plus élevés d'acceptation de cette procédure par les patients et les cliniciens comme moyen de traitement de la dysfonction érectile. Cependant, l'expertise est limitée à un petit nombre de chirurgiens. Malgré cela, il s'agit d'une approche sûre et efficace pour gérer la dysfonction érectile sévère pour les patients en Chine, et lorsqu'elle est effectuée par des chirurgiens expérimentés sur la base de protocoles standardisés, de faibles taux de complications peuvent être atteints tout en offrant aux patients et à leurs partenaires sexuels des niveaux élevés de satisfaction.
RESUMO
This study examines various methods for modelling the electron density and, thus, the electrostatic potential of an organometallic complex for use in crystal structure refinement against 3D electron diffraction (ED) data. It focuses on modelling the scattering factors of iron(III), considering the electron density distribution specific for coordination with organic linkers. We refined the structural model of the metal-organic complex, iron(III) acetylacetonate (FeAcAc), using both the independent atom model (IAM) and the transferable aspherical atom model (TAAM). TAAM refinement initially employed multipolar parameters from the MATTS databank for acetylacetonate, while iron was modelled with a spherical and neutral approach (TAAM ligand). Later, custom-made TAAM scattering factors for Fe-O coordination were derived from DFT calculations [TAAM-ligand-Fe(III)]. Our findings show that, in this compound, the TAAM scattering factor corresponding to Fe3+ has a lower scattering amplitude than the Fe3+ charged scattering factor described by IAM. When using scattering factors corresponding to the oxidation state of iron, IAM inaccurately represents electrostatic potential maps and overestimates the scattering potential of the iron. In addition, TAAM significantly improved the fitting of the model to the data, shown by improved R1 values, goodness-of-fit (GooF) and reduced noise in the Fourier difference map (based on the residual distribution analysis). For 3D ED, R1 values improved from 19.36% (IAM) to 17.44% (TAAM-ligand) and 17.49% (TAAM-ligand-Fe3+), and for single-crystal X-ray diffraction (SCXRD) from 3.82 to 2.03% and 1.98%, respectively. For 3D ED, the most significant R1 reductions occurred in the low-resolution region (8.65-2.00â Å), dropping from 20.19% (IAM) to 14.67% and 14.89% for TAAM-ligand and TAAM-ligand-Fe(III), respectively, with less improvement in high-resolution ranges (2.00-0.85â Å). This indicates that the major enhancements are due to better scattering modelling in low-resolution zones. Furthermore, when using TAAM instead of IAM, there was a noticeable improvement in the shape of the thermal ellipsoids, which more closely resembled those of an SCXRD-refined model. This study demonstrates the applicability of more sophisticated scattering factors to improve the refinement of metal-organic complexes against 3D ED data, suggesting the need for more accurate modelling methods and highlighting the potential of TAAM in examining the charge distribution of large molecular structures using 3D ED.
RESUMO
Electrodialysis (ED) is an eco-friendly and feasible method to separate or recover ionic compounds by electric field attraction and configuration of ion exchange membranes. Strain Burkholderia sp. H-2 could biotransform 5-hydroxymethylfurfural (5-HMF) into a green platform compound, 2,5-furandicarboxylic acid (FDCA), using a bioreactor system. In this study, electrodialysis with the bipolar membrane (EDBM) and traditional ED systems were applied to recover and concentrate FDCA. Artificial and real FDCA effluents of the 5-HMF biotransformation bioreactor were used as the feedstock to establish the optimal conditions for FDCA recovery. The optimal FDCA concentration and pH of the artificial FDCA effluent were 2100 mg/L and 5, respectively. The suitable current density of the EDBM was 8.93 mA/cm2. For FDCA recovery and concentration using the ED, the feedstock volume and FDCA concentration in the concentration chamber were 1.5 L and 1000 mg/L, respectively. The FDCA recovery efficiency of the real FDCA effluent was 55.6 %. Suppose the pretreatment procedure of the real bioreactor effluent is further optimized. It is believed to benefit the enhancement of FDCA recovery efficiency and reduce energy consumption.
RESUMO
Background: Erectile dysfunction (ED) is a prevalent condition in aging men. Meanwhile, platelet-rich plasma (PRP), an emerging treatment alternative, has demonstrated potential in mitigating symptoms associated with ED. Our research aimed to explore the safety and effectiveness of employing PRP as a treatment strategy for ED. Methods: Adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocols, our research involved a thorough search across multiple databases: PubMed, Web of Science, Embase, and the Cochrane Controlled Trials Register. To assess the methodological rigor of the studies selected, we applied the modified Jadad scale and the Methodological Index for Non-Randomized Studies (MINORS) scale as evaluation tools. Subsequent to these evaluations, data analysis was conducted. Results: Our analysis included seven non-randomized studies and three randomized controlled trials (RCTs). These studies showed that the International Index of Erectile Function-Erectile Function (IIEF-EF) scores improved significantly after 1, 3, and 6 months of PRP treatment, with increases of 4.05 [95% confidence interval (CI): 2.42, 5.68; P<0.001], 3.73 (95% CI: 2.93, 4.53; P<0.001), and 3.92 (95% CI: 3.00, 4.85; P<0.001) respectively, compared to the baseline scores. Additionally, compared to the placebo group, the PRP group showed significantly higher IIEF-EF scores. PRP treatment also had a beneficial impact on minimal clinically important difference (MCID) and peak systolic velocity (PSV). However, no significant differences were found between the PRP and placebo groups in terms of erectile hardness score (EHS) [mean difference (MD) =0.63; 95% CI: 0.26, 0.99; P<0.001] or visual analog scale (VAS) pain scores (MD =0.24; 95% CI: -0.05, 0.54; P=0.11). Conclusions: Our study results demonstrated significant efficacy and safety of PRP in treating ED. Due to the fact that most of the literature we included was single-arm studies, it was imperative for future research to provide higher-quality evidence for validation.
RESUMO
Duchenne Muscular Dystrophy (DMD) is a devastating X-linked genetic disorder characterized by progressive muscle degeneration due to mutations in the dystrophin gene. This results in the absence or dysfunction of the dystrophin protein, leading to muscle weakness, loss of ambulation, respiratory issues, and cardiac complications, often leading to premature death. Recently, antisense oligonucleotide (ASO)-mediated exon skipping has emerged as a promising therapeutic strategy for DMD. Notably, the FDA has conditionally approved four ASO therapies for DMD, with numerous others in various stages of clinical development, indicating the growing interest and potential in this field. To enhance ASO-based therapies, researchers have explored the novel concept of conjugating peptides to the phosphorodiamidate morpholino backbone (PMO) of ASOs, leading to the development of peptide-conjugated PMOs (PPMOs). These PPMOs have demonstrated significantly improved pharmacokinetic profiles, potentially augmenting their therapeutic effectiveness. Despite the optimism surrounding ASOs and PPMOs, concerns persist regarding their efficacy and safety. To comprehensively evaluate these therapies, it is imperative to expand patient populations in clinical trials and conduct thorough investigations into the associated risks. This article provides a comprehensive review and discussion of the available data pertaining to adverse reactions and toxicology associated with FDA-approved ASO drugs for DMD. Furthermore, it offers insights into the emerging category of peptide-conjugated ASO drugs those are clinical and preclinical trials, shedding light on their potential benefits and challenges.
RESUMO
Background: Vasopressors remain an important strategy for managing spinal anesthesia-induced hypotension in women with preeclampsia. The aim of this study was to investigate the ED90s and efficacy ratio of phenylephrine and norepinephrine in managing spinal anesthesia-induced hypotension in women with preeclampsia during cesarean delivery. Methods: 60 women with preeclampsia, who underwent cesarean delivery, were randomly assigned to receive either a continuous intravenous infusion of phenylephrine or norepinephrine following spinal anesthesia. The initial dosage of phenylephrine or norepinephrine for the first women was 0.5 or 0.05 µg/kg/min, respectively, and subsequent infusion dosages were adjusted based on their efficacy in preventing spinal anesthesia-induced hypotension (defined as a systolic blood pressure less than 80% of the baseline level). The incremental or decremental doses of phenylephrine or norepinephrine were set at 0.1 or 0.01 µg/kg/min. The primary outcomes were the ED90s and efficacy ratio of phenylephrine and norepinephrine infusions for preventing spinal anesthesia-induced hypotension prior to delivery. Results: The results obtained from isotonic regression analysis revealed that the ED90 values of the phenylephrine and norepinephrine group for preventing spinal anesthesia-induced hypotension were 0.597 (95% CI: 0.582-0.628) and 0.054 (95% CI: 0.053-0.056) µg/kg/min, respectively, with an efficacy ratio of 11.1:1. The results of Probit regression analysis revealed that the ED90 values were determined to be 0.665 (95% CI: 0.576-1.226) and 0.055 (95% CI: 0.047-0.109) µg/kg/min, respectively, with an efficacy ratio of 12.1:1. Conclusion: The administration of 0.6 µg/kg/min phenylephrine and 0.05 µg/kg/min norepinephrine has been found to effectively manage a 90% incidence of spinal anesthesia-induced hypotension in women with preeclampsia.

Emergency department (ED) lengths of stay (LOS) may be unnecessarily extended by inefficient consulting processes. Delays in initiating consultations, returning calls, consultant evaluation of patients, and communication of recommendations can contribute to potentially avoidable increases in LOS. Prolonged ED LOS has been shown to increase patient morbidity and mortality and to decrease patient satisfaction. We created a standardized procedure for ED-initiated consultations, with the goal of reducing the time to initial consultant callback, time to admission, and total ED LOS. Following our intervention, time to consultant callback was decreased; however, there was no reduction in total ED LOS for admitted patients.
RESUMO
BACKGROUND: Patients with Functional Somatic Symptoms (FSS) are frequently encountered within healthcare settings such as Emergency Departments (ED). There is limited research regarding characterisation and frequency of FSS within frequent presenters to ED and no previous Australian evidence. This study aims to fill this gap. METHODS: A retrospective, single-centre study of frequent ED presenters over a 6-month period was undertaken. Patients with > 3 re-presentations/month were reviewed for the presence of FSS using Stephenson and Price's (Stephenson DT, Price JR. Medically unexplained physical symptoms in emergency medicine. Emerg Med J. 2006;23(8):595.) categorisation of FSS. Patients were divided into three groups - FSS, possible FSS (pos-FSS) and non-FSS. The characteristics of these groups were compared using descriptive statistics (chi-square tests, Welch's ANOVA). Person-time at risk during the 6-month study period was estimated for patients in each group and incidence of ED presentation for each group was then calculated. Psychological distress indicators for ED presenters with FSS, as noted by the treating clinician, were also analysed. RESULTS: 11% (71/638) of frequent ED presenters were categorised as having FSS and 72% (458/638) as having possible FSS (Pos-FSS). Mean ED presentations in the FSS group during the study period were significantly higher than in the non-FSS and Pos-FSS groups (p < 0.01). Anxiety was found to be the primary psychological distress indicator associated with ED presentations with FSS. CONCLUSION: We found that, amongst frequent ED presenters, patients with FSS presented significantly more frequently to ED than those without FSS. We propose revising the model of care for FSS in ED to promote appropriate referral to therapy services as a possible demand reduction strategy to improve patient care and efficiency in ED.

BACKGROUND: Although atopic diseases and associated co-morbidities are prevalent in children, little is known about racial differences in emergency department (ED) visitation. OBJECTIVE: We sought to examine racial differences in ED visitation among children with allergic comorbidities. METHODS: We conducted a retrospective study of patients (<21 years) who visited the ED at a large pediatric hospital for atopic dermatitis (AD), food allergy (FA), asthma, allergic rhinitis (AR), and eosinophilic esophagitis (EoE) from 2015 to 2019. We determined the probability of ED encounter-free using hazard ratios (HR) and time to recurrence (TTR) of ED encounter for patients identified as Black/African American (AA) and White/European American (EA). We assessed potentially underlying allergic, demographic, and place-based factors, and potential interactions between factors. RESULTS: A total of 30,894 patients (38% AA, 62% EA) had 83,078 ED encounters (38,378 first ED encounters, and 44,700 recurrent ED encounters) during the study period. Asthma and AR showed the highest rate of comorbidity in ED encounters in both AA and EA children. AA children exhibited higher HR for encounter following index AD and asthma encounters. We found an interaction between the type of insurance and race in ED encounters for AD, FA, AR, and EoE. In AA children, those insured by Medicaid demonstrated a higher HR for any encounter compared to those with commercial insurance. Conversely, in EA children, those with Medicaid insurance showed a lower HR compared to their commercially insured peers. Regardless of race, allergic comorbidity increased the HR of ED encounter (1.12-1.62) for all allergic diseases. At 5-years follow up, mean differences in TTR were shorter in AA children compared to EA children in AD, FA, and asthma. CONCLUSION: Identification of disease-specific racial disparities in ED visitation related to atopic diseases is a necessary first step toward the design and implementation of interventions capable of equitably reducing emergency care in atopic comorbid children.

Same extract showed the best antioxidant activity with an IC50 value of 0.71 mg/mL for DPPH and 0.38 mg/mL for ABTS assay, as well as the highest content of gallic acid, caffeic acid, and hyperoside 0.04 mg GAE/g DW, 0.60 mg CA/g DW and 2.61 mg HYP/g DW, respectively, determined by HPLC-ED. Vitexin was not detected. The extract of berries obtained by ultrasound extraction had the highest amount of total anthocyanins (1.69 mg/100 g DW).
RESUMO
PURPOSE: This study compared the effects of calcium oxalate stones and uric acid stones on male sexual function. METHODS: We enrolled 100 patients with ureteral stones. According to the composition of the stones, they were divided into the calcium oxalate stone group and the uric acid stone group. All patients underwent ureteroscopic holmium laser lithotripsy. General data such as age, body mass index, course of disease, stone diameter, and degree of renal hydronephrosis were compared. Sperm parameters, including sperm density, sperm viability, and sperm deformity rate, as well as International Index of Erectile Function-5 questionnaire (IIEF-5) scores, and Quality of Life (QOL) scores, were measured and compared before and 6 weeks after the surgery. RESULTS: There were no statistically significant differences in general data and sperm parameters between the two groups before the surgery (P > 0.05). However, there were significantly lower IIEF scores but significantly higher QOL scores in the uric acid stone group. In the calcium oxalate stone group, there were no statistically significant differences in sperm parameters, IIEF score, and QOL score before and after the surgery (P > 0.05). In the uric acid stone group, there were no statistically significant differences in sperm parameters before and after surgery (P > 0.05), whereas there were significantly higher IIEF scores but significantly lower QOL scores after the surgery (P < 0.05). The prevalence of erectile dysfunction (ED) in the uric acid stone group was 38.18% (21/55), which was significantly higher compared to 20.00% (9/45) in the calcium oxalate stone group (P < 0.05). The multivariate binary logistic regression analysis showed that the independent risk factor related to ED was uric acid stones (odds ratio: 2.637, 95% confidence interval 1.040-6.689, P = 0.041). No statistically significant differences were found in sperm parameters between patients with and without ED. CONCLUSION: Compared with the calcium oxalate stone group, patients with uric acid stones had a higher prevalence of ED and poorer sexual performance.
RESUMO
BACKGROUND: Emergency department (ED) crowding is a global burden. Interventions to reduce ED utilization have been widely discussed in the literature, but previous reviews have mainly focused on specific interventions or patient groups within the EDs. The purpose of this scoping review was to identify, summarize, and categorize the various types of non-ED-based interventions designed to reduce unnecessary visits to EDs. METHODS: This scoping review followed the JBI Manual for Evidence Synthesis and the PRISMA-SCR checklist. A comprehensive structured literature search was performed in the databases MEDLINE and Embase from 2008 to March 2024. The inclusion criteria covered studies reporting on interventions outside the ED that aimed to reduce ED visits. Two reviewers independently screened the records and categorized the included articles by intervention type, location, and population. RESULTS: Among the 15,324 screened records, we included 210 studies, comprising 183 intervention studies and 27 systematic reviews. In the primary studies, care coordination/case management or other care programs were the most commonly examined out of 15 different intervention categories. The majority of interventions took place in clinics or medical centers, in patients' homes, followed by hospitals and primary care settings - and targeted patients with specific medical conditions. CONCLUSION: A large number of studies have been published investigating interventions to mitigate the influx of patients to EDs. Many of these targeted patients with specific medical conditions, frequent users and high-risk patients. Further research is needed to address other high prevalent groups in the ED - including older adults and mental health patients (who are ill but may not need the ED). There is also room for further research on new interventions to reduce ED utilization in low-acuity patients and in the general patient population.

PURPOSE: To compare compliance with the French national guidelines before and after the implementation (in 2018) of a new protocol on acute fracture pain management in the pediatric emergency department of a French university medical center. METHODS: We conducted a retrospective, before-after study in patients aged below 16 years presenting at the pediatric emergency department with a fracture. We compared pain management before (in 2017) and after (in 2019 and 2020) implementation of the new procedure. The primary endpoint was appropriate pain management, defined as (i) an appropriate initial assessment of pain, (ii) appropriate treatment with analgesic drugs (acetaminophen for mild pain, acetaminophen and ibuprofen for moderate pain, ibuprofen and morphine for severe pain) and (iii) reassessment of the pain intensity. RESULTS: 572 patients were included (mean age: 6.5 years; male: 60%). 190 in 2017 and 382 in 2019-2020. Pain management was appropriate for 40% of the patients in 2017 and 52% in 2019-2020 (p = 0.004). Pain was rated for 98% of patients in 2017 vs. 100% in 2019-2020 (p = 0.04). The frequency of appropriate treatment for mild pain and moderate pain increased significantly from 52 to 76% and from 0 to 44%, respectively. The administration of ibuprofen increased by 26% points (from 3 to 20 patients treated) and the administration of morphine increased by 29% points (from 1 to 17 patients treated). Pain reassessment rose significantly from 21 to 43%. Levels of compliance with the guidelines were similar in 2019 and 2020. Analgesia was significantly more effective in 2019-2020 than in 2017 (in 20% vs. 14% of the patients, respectively; p = 0.005). CONCLUSION: After the implementation of a new protocol for the management of acute fracture pain, we observed an increase in compliance with the guidelines. Although the use of ibuprofen and morphine rose significantly as did the frequency of pain reassessment, further improvements are required.
