Abstract Background The BioFire® FilmArray Meningitis/Encephalitis (ME) panel delivers timely CSF analysis when meningitis or encephalitis is suspected and has the potential for earlier optimization of patient care. It is unclear if the M/E panel provides incremental benefit over standard microbiologic methods such as culture and cell counts, especially in the absence of significant pleocytosis. We evaluated the clinical utility of the ME panel with respect to CSF white blood cell count per high power field (WBC/hpf) and patient age. Methods We identified paired CSF ME panels and CSF cultures collected throughout a large healthcare system from 2016–May 2021 in children < 18 years of age. CSF results from the same calendar day were included in the dataset. We reviewed standalone HSV and Enterovirus (EV) CSF studies to determine frequency of duplicative testing. Results were stratified by CSF WBC/hpf and patient age (< 14 days, 14–60 days, > 60 days and < 5 years, and > 5 years). Results 1045 paired cultures and ME panels were identified. Of those, 921 (88%) ME panels were negative, but 5 of those cultures grew bacteria. Of 124 (12%) positive ME panel results, 66% were viral: 46 (37%) EV, 22 (18%) HHV-6 and 6 (5%) parechovirus. In 498 cases, ME panels were sent when CSF had < 10 WBC/hpf, resulting in only 2 (0.4%) PCRs positive for bacteria, one which was gram stain positive and the other was considered a false positive (Table 1). In addition to a ME panel, standalone PCRs for enterovirus and HSV were sent in 134 (13%) and 213 (20%) of cases, respectively, with < 2% discordance. Pathogen distribution by ME panel did not vary with age (Table 2). Meningitis and encephalitis panel, standalone PCR and culture results overall and by age group. Conclusion In our cohort, the ME panels were overwhelmingly negative. Only 12% of ME panels were positive, mostly with self-limited viral pathogens (e.g., EV, parechovirus). Performance was worse when samples had < 10 WBC/hpf. Duplicative testing was common and had no benefit. Performance was similar across age groups. More targeted use of the ME panel could improve the utility and efficacy of this test.

The research regarding the duration of nursing care in patients with hip fractures was conducted at the Traumatology and Orthopedic Institute of the University Hospital Dubrava in a period of 4 months. The research was conducted on 59 patients with a diagnosis of a broken hip, that have undergone surgery. The goal of this research was to determine the differences in the duration of nursing care due to age, gender, comorbidities and postoperative day. Statistical significance in all measurements was reduced to p<0.05. The research shows connection between patient age and the duration of nursing care. The presence of comorbidity also prolongs the duration of nursing care. Shorter duration of nursing care was determined in women compared to men in all age groups, but it wasn’t of statistical significance.

Olfactory neuroblastoma (ONB) is a rare neuroepithelial-derived malignancy that usually presents in the nasal cavity. The rarity of ONB has led to conflicting reports regarding associations of patient age and ONB survival and outcome. Moreover, long-term outcomes of chemotherapy and other treatment modalities are speculated. Here, we aimed to compare survival outcomes across age groups through time and determine associations between treatment modality and survival. In this retrospective population-based study, we analyzed the SEER 2000–2016 Database for patients with ONB tumors. Using Kaplan–Meier survival analysis, a significant effect of age and cancer-specific survival (CSS) was observed; geriatric ONB patients had the lowest CSS overall. Generalized linear models and survival analyses demonstrated that CSS of the pediatric patient population was similar to the geriatric group through 100 months but plateaued thereafter and was the highest of all age groups. Radiation and surgery were associated with increased CSS, while chemotherapy was associated with decreased CSS. GLM results showed that tumor grade, stage and lymph node involvement had no CSS associations with age or treatment modality. Our results provide insight for future investigations of long-term outcomes associated with ONB patient age and treatment modality, and we conclude that survival statistics of ONB patients should be analyzed in terms of trends through time rather than fixed in time.

Abstract It is estimated that the prevalence of adrenal incidentaloma increases with age: ~3% of those aged 50 years, rising to 10% in those >70 years (1). Given the aging population together with increased utilisation of cross-sectional imaging in the UK (eg CT urogram, MR angiogram), we explored the proportion of patients with adrenal incidentaloma by age based on current imaging trends. Furthermore, there is no information currently available on the relationship between age and pattern of endocrine referrals. We extracted data for all CT and MRI scans from Jan 2018-Oct 2019 and used key phrases in radiology reports (eg adrenal adenoma/lesion/mass/nodule/incidentaloma, incidental adrenal, indeterminate adrenal) to identify potential lesions. We also extracted data on patient age and referral patterns as identified by a logged referral or an attendance (new or follow-up) to endocrine clinic 3 months post index scan, stratified by 10 year age groups. Where possible, we excluded false hits (eg no adrenal lesion). Preliminary data showed that, of the 2604 potential lesions identified by CT and MRI scans, 78.7% were on patients aged over 60 years. The numbers of identified lesions gradually increased with age to a peak in the 71-80 year age group after which these declined. Whilst patients younger that 60 years had fewer potential lesions identified, they were more likely to be referred to endocrine services (73 out of 55 patients; 13.2%) than those in the older age group (168 out of 2049; 8.2%; p<0.001). Indeed there was a statistically significant trend towards decreasing referral with age group (Chi-squared test for trend; p<0.001). In conclusion, patients over 60 years have a higher number of potential adrenal incidentalomas. However, this group is less likely to be referred for endocrine evaluation. This is particularly concerning given the large number of scans requested and the higher prevalence of incidentalomas in this age group. This study represents preparatory work on innovations to enhance case detection, particularly in the older age groups (2). 1. Fassnacht M, Arlt W, Bancos I, et al.

Purpose To assess digital patient briefing as an alternative to conventional paper documentation. Materials and Methods 502 patients with a planned computed tomography (CT) examination were selected for digital patient briefing using the E-ConsentPro software from Thieme Compliance on an iPad by Apple (Cupertino, California, USA). For the analysis, three age groups were formed. The time required for the patient briefing, the number of open questions as well as the time needed for discussion with physicians were determined. Student’s t-test was performed to assess statistical significance. Results There was no significant difference between patient age and briefing time which was about 20 minutes on average. The number of open or unclear questions increased with patient age. While patients younger than 30 years of age had about 2 open questions, patients over 30 and 60 years had about 4 and 5 questions, respectively. The total time needed for discussion with physicians was less than 2 minutes on average. A significant difference in the time required for discussion with physicians could not be observed between the individual age groups. Conclusion Tablet-based digital briefing allows the storage of patient documents with reasonable time and effort. Furthermore, it minimizes the risk of data loss. Key Points  Citation Format

Abstract Abstract 1178 Background: Effectively cryopreserving hematopietic peripheral blood progenitor cells (HPC(A)) until time of transplant is critical for successful autologous stem cell transplant. It is important to demonstrate long-term HPC(A) viability and recovery and also to identify patient characteristics that may influence this. We evaluated HPC(A) products cryopreserved over 16 year period. We analyzed potential correlations between total nucleated cell (TNC) and CD34+ recovery and viability and patient age, initial collection, and impact of stem cell mobilization regimen. Method: Samples were obtained from expired patients, chosen based on storage duration but randomly selected in regard to patient and product characteristics; 23 samples were obtained from 18 patients. Five patients had 2 samples each; for duplicate samples, data were averaged (collection dates and thaw dates were similar). All HPC(A) products were frozen in autologous plasma and 10% DMSO, then stored in liquid phase or vapor phase nitrogen. Products were uniformly thawed and washed to remove DMSO. Analysis included 7-Amino-actinomycin D viability, TNC and CD34+ cell counts and recovery. Some samples had post-thaw CD34+ cell counts that exceeded pre-thaw count; for these, the recovery was set to 100%. Spearman rank correlations were used to analyze association between the different parameters. Wilcoxon rank sum test and analysis of covariance were used to compare patient groups. Result: Median patient age at time of stem cell collection was 54 (range 2–75) years. A majority of patients had lymphoma (61%) or multiple myeloma (22%). Most (56%) were mobilized using G-CSF+VP16, 33% with G-CSF alone, and 11% other. Samples were cryopreserved for a median of 8 years (range 1–16). Median (range) for total CD34+ × 106 collected was 547 (43-5845). Median (range) for CD34+/kg × 106 was 8 (1-59). Median (range) count/bag for TNC × 108 was 144 (37-285) and for CD34+ × 106 was 105 (8-805). Median (range) recovery and viability were 85% (32-213%), and 70% (46-85%) respectively for TNC; and 97% (16-359%) and 80% (61-98%), respectively for CD34+ cells. Pre- and post- thaw TNC and CD34+ counts were both highly correlated (r=0.95, p<.0001 in both cases – figures 1a and b). There was no significant association between TNC recovery and viability (r=-0.07, p=.79) or between CD34+ cell recovery and viability (r=-0.21, p=.41). Storage duration did not impact CD34+ recovery or viability (r=-0.01, p=.98 and -0.18, p=.47, respectively); or TNC viability (r=-0.13, p=.62). There was, however a significant positive correlation between the storage duration and TNC recovery (r=0.81, p<.0001). Age did not significantly impact TNC or CD34+ recovery (r=-0.05, p=0.86, and r=-0.26, p=0.29, respectively); however there was suggestion of negative impact on viability (r=-0.45, p=0.06 and r=-0.42, p=0.08, respectively, figures 1a and 1b). Overall, there did not appear to be a correlation between the initial TNC count/bag or total CD34+ cell dose on recovery or viability (r=0.29, r=-0.22, r=0.18, r=-0.38, respectively; all p>0.12). However, when patients were stratified according to total collection >25×106 CD34+ cells/kg or ≤25 × 106 CD34+ cells/kg, there was better %CD34+ cell count recovery between groups (p = 0.07, median recovery 81% for 13 patients with ≤25 × 106 CD34+ cells/kg and 100% for 5 patients with >25×106 CD34+ cells/kg). For mobilization regimen, there was no significant difference in TNC recovery or viability (p = 0.19 and p=0.76, respectively) or CD34+ viability (p = 0.53), however there was suggestion that CD34+ recovery was greater with G-CSF+VP16 (p=0.06, see figure 2), independent of storage time. Conclusion: Products cryopreserved for 16 years retain acceptable recovery and viability. Unexpectedly, storage duration positively correlated with TNC recovery, and CD34+ cell recovery of >100% was noted in several samples. Reasons for this are unclear, but are likely related to changes in enumeration method or use of methods validated for counting fresh cells. Patient age was suggested to negatively impact post-thaw HPC(A) viability. Our data also suggested that the mobilization regimen or the CD34+ cell collection yield may affect the CD34+ cell recovery, possibly reflecting differences in graft characteristics. The number of patients included is relatively small and these findings warrant further studies for validation. Disclosures: No relevant conflicts of interest to declare.

Abstract Background Intracranial extension of sinusitis is a rare complication. Non-specific presentations are a diagnostic challenge, and complications include long-term neurologic sequelae. Early recognition is critical, although optimal management remains poorly characterized. Methods We conducted a retrospective chart review of 123 patients admitted to Primary Children’s Hospital between 2004-2019 with ICD9 and ICD10 codes for sinusitis and intracranial suppurative infection. Chart review confirmed cases in patients &lt; 18 years with evidence of sinusitis and intracranial extension. Variables collected included: demographic data, clinical presentation, microbial profile, clinical management, and outcomes. Results We observed 84 pediatric sinogenic intracranial infections between 2004-2019. Incidence significantly increased over the interval. Median patient age was 12.8 years (IQR 10.5-14.7 years); most were male (n=52). The most common presenting symptoms were headache and fever. Most patients (n=80) required surgical management; 62 required neurosurgery. All but one patient survived. Most infections were polymicrobial (n=47). Streptococcus anginous group were most frequently identified (n=32). All patients were started on vancomycin empirically; only 10 required use for definitive management. Most patients were treated with a carbapenem (n=42) or ceftriaxone plus metronidazole (n=32). Average duration of antibiotics was 44 days (IQR 38-55 days). The most common complication was epilepsy (n=11). Patients with Streptococcus sp. infections were more likely to experience adverse outcomes (p= 0.04). We observed significantly decreased carbapenem use following introduction of an antimicrobial stewardship program in 2012, with no change in clinical outcomes. Annual incidence of Sinogenic Intracranial Infections Shown is the increasing incidence of sinogenic intracranial infections annually in the state of Utah/100,000 children. Conclusion Sinogenic intracranial infections are increasingly frequent severe pediatric infections with associated long term neurologic sequelae. Most patients require both surgical and long-term IV antibiotic treatment. Most infections are polymicrobial. Streptococcus sp. are commonly identified. Antibiotic resistant bacteria are rare. The combination ceftriaxone and metronidazole is appropriate for treatment of most infections.

Abstract Background: Long-term survival in NK-AML is influenced by different clinical and molecular markers. Whereas the presence of a NPM-1 mutation is associated with a positive prognostic effect on long-term outcome, the presence of a FLT3-ITD mutation has a negative impact on survival. Interestingly, a significant interaction between NPM-1 and FLT3-ITD mutations has been shown. The positive prognostic impact on clinical outcome was evident predominantly in patients with NK-AML carrying NPM1 gene mutations when FLT3-internal tandem duplications (ITD) were absent. In contrast, the survival in all other groups of NPM-1 and FLT3-ITD combinations was not different so far. A clinical parameter with negative impact on all outcome parameters (OS, EFS, RFS, CR) is patient age at diagnosis. Certainly the worse prognosis in elderly patients is due to adverse patient characteristics and comorbidities. Nevertheless also disease-associated parameters reveal differences between older and younger patients with AML. Therefore we investigated the frequencies of NPM-1/FLT3-ITD mutations in different age groups. Patients and methods: Analyses were based on 803 patients with NK-AML included in the AMLCG (German AML Cooperative Group) 2000 trial until 01/2006. Patient age ranged from 17 to 85 years (median: 60 yrs). Information about the mutation status of NPM-1 and FLT3-ITD mutations at diagnosis was available in 689 patients. Patients were divided into six age groups (1: 17–30yrs; 2: 31–40yrs; 3: 41–50yrs; 4: 51–60yrs; 5: 61–70yrs; 6: 71–85yrs). The incidence of the molecular markers NPM-1 and FLT3-ITD as well as the four NPM-1 and FLT3-ITD combinations were calculated in cross tables (Pearson’s Chi Square test) in the different age groups. Results: In 689 patients with available mutations status we found a significant decrease in the frequency of the two molecular markers with higher age. Whereas the incidence of NPM-1 mutation decreased abruptly in patients &gt;60 yrs [Group 1: 18/28 (64.3%), 2: 35/59 (59.3%), 3: 70/114 (61.4%), 4: 84/143 (58.7%), 5: 98/234 (41.9%), 6: 46/111 (41.4%); p&lt;0.0001], the incidence of a FLT3-ITD decreased continuously with increasing age [Group 1: 14/28 (50.0%), 2: 21/59 (35.6%), 3: 36/114 (31.6%), 4: 47/143 (32.9%), 5: 60/234 (25.6%), 6: 22/111 (19.8%); p=0.013)]. Combining both markers we found a significant relative increase of NPM-1−/FLT3-ITD− patients (p&lt;0.0001) with a sharp cut at 60 years whereas the NPM-1+/FLT3-ITD+ group diminished continuously (p=0.020). The proportion of the positive prognostic group of NPM-1+/FLT3-ITD− patients showed an increase between 40–60 years and a decrease afterwards (p=0.024) (see table 1 and figure 1). Conclusions: Our data show in a large cohort of 689 patients with NK-AML that the presence of mutations of the molecular markers NPM-1 and FLT3-ITD significantly decreases with age. Consequently the proportion of NPM-1−/FLT3-ITD− patients increases over time. This observation sheds light on the disease biology in older patients with AML.
