RESUMO
Using an electronic health record-based algorithm, we identified children with Coronavirus disease 2019 (COVID-19) based exclusively on serologic testing between March 2020 and April 2022. Compared with the 131â537 polymerase chain reaction-positive children, the 2714 serology-positive children were more likely to be inpatients (24% vs 2%), to have a chronic condition (37% vs 24%), and to have a diagnosis of multisystem inflammatory syndrome in children (23% vs <1%). Identification of children who could have been asymptomatic or paucisymptomatic and not tested is critical to define the burden of post-acute sequelae of severe acute respiratory syndrome coronavirus 2 infection in children.

AIM: Bowel dysfunction after colon cancer (CC) surgery is widely neglected in current follow up programmes. This study explored changes in bowel function and quality of life (QoL) from three (3 m) to twelve months (12 m) after surgery in CC patients undergoing right- or left-sided colon resection (RightSCR/LeftSCR) and investigated differences between the two groups 12 m after surgery. METHOD: CC patients undergoing surgical resection in 2018-2020 at five surgical departments were included in this population-based prospective cohort study. Included patients completed electronic surveys consisting of a collection of validated scores 3 m and 12 m after surgery. RESULTS: A total of 708 CC patients (423 RightSCR, 285 LeftSCR) were included. In RightSCR, no improvement was observed from 3 m to 12 m in most scores/items, on the contrary, symptom worsening in flatus- and faecal incontinence and urgency was observed (p < 0.05). Also, the proportion of patients rating their bowel function as very good/good decreased (p < 0.05) in this group. In LeftSCR improvement was found in flatus and faecal incontinence, urgency and night-time defaecation (p < 0.02), while no improvement was observed in the remaining scores/items. At 12 m, higher proportions of RightSCR than LeftSCR reported loose stools, incontinence and urgency (all p < 0.001), whereas LeftSCR more often reported hard stools and flatus incontinence (p < 0.05). Among all CC patients 18.3% reported bowel-related impairment of QoL at 12 m with no differences between the two groups. CONCLUSION: From 3 m to 12 m no significant change was observed in the majority of bowel function and QoL scores/items, however, some symptoms worsened in RightSCR, while a few improved in LeftSCR. Bowel dysfunction and impaired QoL were still common in both groups at 12 m, although the symptom pattern differed between the groups. These findings call for a systematic screening for bowel dysfunction to ensure early treatment of symptoms.

OBJECTIVE: The aim of this study was to translate and validate the chronic pain score (CP score) in a cohort of colon cancer patients. Chronic pain following colon cancer surgery is still poorly understood, in particular the lack of a validated tool for measuring chronic pain is a major issue as such an instrument is critical for evaluating the incidence and risk factors. The CP score was created using data from Danish rectal cancer patients. METHODS: Danish colorectal cancer survivors diagnosed between 2001 and 2014 completed the CP score and two quality of life (QoL) measures. Clinical data were obtained from a national database. Convergent validity was investigated by testing the association of the CP score with a single ad hoc QoL item and the EORTC QLQ-C30, and discriminative validity was tested as the score's ability to differentiate between gender and age groups. Sensitivity and specificity were evaluated by determining the ability of the score to identify patients with a major impact of pain on QoL. RESULTS: Responses from 7127 colon cancer were included. Convergent validity was confirmed, as the score was associated with both QoL measures (p < 0.001). Moreover, the score could differentiate between males/females and older/younger patients (p < 0.001, respectively), reflecting high discriminative validity. Finally, the score was able to identify patients with a major impact on QoL, with a sensitivity of 87% and specificity of 82%. CONCLUSION: The CP score is a valid tool for measuring chronic pain after colon cancer surgery and should be used to homogenize outcomes in future studies.

We are reviewing the current state of knowledge on the virological and immunological correlates of long COVID, focusing on recent evidence for the possible association between the increasing number of SARS-CoV-2 reinfections and the parallel pandemic of long COVID. The severity of reinfections largely depends on the severity of the initial episode; in turn, this is determined both by a combination of genetic factors, particularly related to the innate immune response, and by the pathogenicity of the specific variant, especially its ability to infect and induce syncytia formation at the lower respiratory tract. The cumulative risk of long COVID as well as of various cardiac, pulmonary, or neurological complications increases proportionally to the number of SARS-CoV-2 infections, primarily in the elderly. Therefore, the number of long COVID cases is expected to remain high in the future. Reinfections apparently increase the likelihood of long COVID, but less so if they are mild or asymptomatic as in children and adolescents. Strategies to prevent SARS-CoV-2 reinfections are urgently needed, primarily among older adults who have a higher burden of comorbidities. Follow-up studies using an established case definition and precise diagnostic criteria of long COVID in people with or without reinfection may further elucidate the contribution of SARS-CoV-2 reinfections to the long COVID burden. Although accumulating evidence supports vaccination, both before and after the SARS-CoV-2 infection, as a preventive strategy to reduce the risk of long COVID, more robust comparative observational studies, including randomized trials, are needed to provide conclusive evidence of the effectiveness of vaccination in preventing or mitigating long COVID in all age groups. Thankfully, answers not only on the prevention, but also on treatment options and rates of recovery from long COVID are gradually starting to emerge.

AIM: The aim of this study was to test the feasibility of a new method for systematic screening for late sequelae (LS) following colorectal cancer treatment. METHOD: Patients with colorectal cancer from five Danish hospitals were invited to complete a survey about LS at 3, 12, 24 and 36 months after surgery as part of their follow-up. The survey consisted primarily of validated tools, supplemented by a few ad hoc items, measuring bowel, urinary and sexual dysfunction, pain and quality of life and an additional question regarding request for contact. Patients completed surveys electronically or on paper. RESULTS: Of the 1721 invited patients, 1386 (80.5%) were included (1085 with colon cancer and 301 with rectal cancer) of whom 72.5% responded electronically. Patients responding electronically were 7.6 years younger than those responding on paper (P < 0.001). Since some patients answered more than once, the dataset consisted of 2361 surveys. Patients with colon cancer requested phone contact in 19.0% of the surveys, and 8.4% were referred to treatment for LS, primarily bowel dysfunction. Among patients with rectal cancer, 30.8% requested phone contact and 16.2% were referred for treatment of LS, mainly due to bowel and sexual dysfunction. CONCLUSION: This is the first paper investigating a new method of systematic screening for LS following colorectal cancer using electronic patient-reported outcome measures. The study shows that in the Danish population a high response rate can be obtained with this method and that close to three-quarters of patients respond electronically. Patients with rectal cancer had a higher need for phone contact and treatment of LS than patients with colon cancer.

As the numbers of acute severe acute respiratory syndrome coronavirus 2 infections continue to rise, we are learning that symptoms do not resolve quickly in all patients. Although why some patients experience persistent symptoms is not clear, these individuals suffer. Long-hauler is the term that is associated with these persistent symptoms, and this review of the literature provides information to nurse practitioners working in primary care about symptoms, risk factors, and resources for disease management.
RESUMO
BACKGROUND: Invasive mold disease (IMD) is a severe infectious complication in immunocompromised patients. The outcome of central nervous system (CNS) IMD is poor, but contemporary data, in particular in the pediatric setting, are lacking. PROCEDURE: For this retrospective multicenter analysis, pediatric patients < 18 years with proven or probable CNS IMD receiving chemotherapy or undergoing allogeneic HSCT were reported by the local investigator. CNS IMD had to be diagnosed between 2007 and 2016. Proven CNS IMD was defined as compatible CNS imaging or macroscopic autopsy findings in conjunction with a positive microscopic or microbiological result in the brain tissue or cerebrospinal fluid. Probable CNS IMD was defined as compatible CNS imaging findings in combination with proven or probable IMD at a site outside the CNS. RESULTS AND CONCLUSIONS: A total of 29 patients (median age, 14 years; 14 allogeneic HSCT recipients) were diagnosed with proven (n = 12) or probable (n = 17) CNS IMD. Aspergillus spp. was the most common fungal pathogen. All but one patient had IMD sites outside the CNS and eight patients (27.6%) were neurologically asymptomatic at diagnosis of CNS IMD. Forty-nine percent of the patients survived CNS IMD; however, 46.7% of the survivors suffered from severe long-term neurological sequelae. Our data suggest that (1) outcome of CNS IMD has improved in children as compared with previous series, (2) half of surviving patients suffer from severe neurological sequelae, and (3) imaging of the CNS should be performed in all children with IMD irrespective of neurological symptoms.

Testicular germ cell tumors (TGCTs) are the most prevalent malignancies in young Caucasian men. Clinical stage I (CSI) TGCTs present the highest cure rate and treatment options after orchiectomy depend on histology and risk factors. Nevertheless, the management of CSI TGCTs is controversial due to the availability of multiple treatments and the lack of randomized trials. An integrated multidisciplinary approach that includes clinicians (surgeons, radiotherapists and oncologists) and psychologists is crucial to maximize the patients' compliance and must be acknowledged with appropriate tools. The aim of our work is to review the oncological and psychological aspects of the decision-making process, discussing the fundamental role of the patient involvement in the personalized management of CSI TGCTs.

BACKGROUND: Rheumatoid arthritis (RA) and cigarette smoking are both risk factors for periodontal disease (PD). Previous research suggests that systemic inflammatory conditions and cigarette smoking may act in synergy, and their co-occurrence leads to a much higher risk of developing severe stage PD than what the combination of their individual risks would suggest. We originally sought to test this in the case of RA, but it turned out that the majority of our patients were former smokers, who smoked for prolonged periods in the past. For that reason, we decided to shift our focus toward the possible effects of past chronic cigarette smoke exposure. METHODS: The data of 73 RA patients and 77 healthy controls were analyzed. The participants received a full-mouth periodontal examination to determine their periodontal status. Rheumatological indices and data on past tobacco use were also recorded. Both the patient and the control groups were divided into former smoker and non-smoker subgroups for the analyses. Non-smoker controls were used as the reference group. RESULTS: In the control group, smoking in history increased the odds of developing both the moderate and the severe stages of PD, but the change was not statistically significant. RA significantly, increased the odds of developing both stages in itself, but the highest odds were seen in the former smoker RA group. CONCLUSION: Based on this surprising observation of ours, we hypothesize that chronic cigarette smoke might bring about permanent changes in the periodontal tissues, leading to their hypersensitivity to inflammatory challenges.

PURPOSE: To report the visual outcome and refractive status in first 3 years of age in preterm infants suffered from laser-treated Type 1 retinopathy of prematurity (ROP): a 6-year review in Hong Kong DESIGN: Retrospective case series METHODOLOGY: Clinical records of all infants suffered from Type 1 ROP who had undergone laser therapy between 2007 and 2012 were retrospectively reviewed. Basic demographic data, serial changes of refractive error, visual acuity, severity of ROP and laser were analyzed. Correlation with myopia and astigmatism progression, body weight, height, growth and gestational age were also analyzed. RESULT: Among 494 babies screened, 14 Chinese babies (26 eyes) recruited with 1:1 male-to-female ratio in this study. All eyes showed gradual progression of myopia in first 3 years of age but no significant change of astigmatism. Further correlation analysis showed no correlation with laser energy consumed, birth weight (p = 0.14), head circumference growth (p = 0.57) and body weight growth (p = 0.71). However, severity of myopia was related to the post-conceptual age when receiving laser therapy (p < 0.005), gestation age (p = 0.02) and possibly body height growth with age (p = 0.05). CONCLUSION: Myopia in early life is one of the most common ocular sequelae in Type 1 ROP survivors. Early detection of refractive error is important for prompt correction and visual rehabilitation to prevent amblyopia.

BACKGROUND: CMV is the most common cause of congenital infection in the whole world (0.2 to 2.2 %). That infection may be symptomatic or asymptomatic at birth and, although asymptomatic cases at birth are more common, some children may develop late sequelae, and require medical intervention. This study aimed to determine the prevalence of CMV congenital infections in children who were born in a public hospital in Ilhéus, Brazil, and to evaluate the clinical progression in infected newborns. METHODS: CMV congenital infection was determined by detecting viral DNA through nested PCR. RESULTS: The viral DNA was detected in 25 newborns, showing a prevalence of 1.19 % (25/2100) of CMV congenital infection. In regards to the risk factors from mothers, only the variables: age of mothers (p = 0.003), number of children (p = 0.011), and use of medications (p < 0.001) were associated with the congenital infection. Approximately 12 % of children presented symptoms. One death and two auditory alterations were detected during the monitored period. Only 50 % of children diagnosed attended their medical follow. CONCLUSIONS: The prevalence found confirms the findings from other studies which involved other poor populations. Two children presented impaired hearing during the monitored period; that was one of the main sequelae from the infection. It is noteworthy that there was low adherence to medical follow-up which may underestimate data on complications of the infection CMV. Late symptoms can be mistaken for other diseases or even go unnoticed.

BACKGROUND: The aim of this study was to compare the nephrotoxicity risk of cisplatin (CPL) and ifosfamide (IFO) combination treatment (CT) with that of CPL alone and to evaluate the prevalence of CPL-induced long-term nephrotoxicity in pediatric cancer survivors (CS). METHODS: A total of 33 patients with pediatric solid tumors who have been cured of their disease were included in the study. They were divided into two groups based on the type of chemotherapeutics, either CPL (n = 21) or CT (n = 12), given during cancer treatment and were evaluated for glomerular and tubular function using the Skinner grading system. RESULTS: Nephrotoxicity was found in 15 CS (45.4%): seven (21.3%) of those had moderate, six (18.2%) had mild, and two (6.1%) had severe nephrotoxicity. Neither the rates of overall nephrotoxicity, glomerular toxicity and tubular toxicity, nor the mean overall, glomerular and tubular toxicity scores differed significantly among the CPL and CT groups (P > 0.05 for all parameters). Cumulative IFO dose and age at treatment were found to be independent risk factors for both development and severity of CPL-induced nephrotoxicity (P = 0.025 and P = 0.036 for development of nephrotoxicity; P = 0.004 and P = 0.050 for severity of nephrotoxicity, respectively). CONCLUSIONS: Although CPL-induced long-term nephrotoxicity was found in half of the pediatric CS of solid tumors, clinically significant nephrotoxicity was detected only in a minority of them. Both higher cumulative IFO dose and younger age at treatment were found to be independent risk factors for both development and severity of CPL-induced nephrotoxicity.

Objective: Long COVID, marked by persistent, recurring, or new symptoms post-COVID-19 infection, impacts children's well-being yet lacks a unified clinical definition. This study evaluates the performance of an empirically derived Long COVID case identification algorithm, or computable phenotype, with manual chart review in a pediatric sample. This approach aims to facilitate large-scale research efforts to understand this condition better. Methods: The algorithm, composed of diagnostic codes empirically associated with Long COVID, was applied to a cohort of pediatric patients with SARS-CoV-2 infection in the RECOVER PCORnet EHR database. The algorithm classified 31,781 patients with conclusive, probable, or possible Long COVID and 307,686 patients without evidence of Long COVID. A chart review was performed on a subset of patients (n=651) to determine the overlap between the two methods. Instances of discordance were reviewed to understand the reasons for differences. Results: The sample comprised 651 pediatric patients (339 females, M age = 10.10 years) across 16 hospital systems. Results showed moderate overlap between phenotype and chart review Long COVID identification (accuracy = 0.62, PPV = 0.49, NPV = 0.75); however, there were also numerous cases of disagreement. No notable differences were found when the analyses were stratified by age at infection or era of infection. Further examination of the discordant cases revealed that the most common cause of disagreement was the clinician reviewers' tendency to attribute Long COVID-like symptoms to prior medical conditions. The performance of the phenotype improved when prior medical conditions were considered (accuracy = 0.71, PPV = 0.65, NPV = 0.74). Conclusions: Although there was moderate overlap between the two methods, the discrepancies between the two sources are likely attributed to the lack of consensus on a Long COVID clinical definition. It is essential to consider the strengths and limitations of each method when developing Long COVID classification algorithms.
RESUMO
Kawasaki Disease (KD) is a self-limited acute vasculitis that mainly affects medium-sized arteries in childhood, with the coronary arteries being one of the main targets. A well-known complication is a coronary aneurysm with myocardial ischemia. We report the case of a 29-year-old female with an insignificant past medical history who presented with sudden cardiac arrest. Labs were significant for elevated troponin, consistent with non-ST elevation myocardial infarction, given diffuse ST depression on the electrocardiogram. The patient underwent a coronary angiogram that revealed diffuse coronary artery disease with multiple ulcerations, aneurysms, and occlusions consistent with KD, despite denying prior history. Cardiac arrest may be the initial presentation of undiagnosed KD and should be considered as one of the differential diagnoses.
RESUMO
PURPOSE: After curatively intended rectal cancer (RC) surgery, new follow-up strategies are warranted, seeking more individualised care and targeting health-related quality of life (HRQoL) and functional outcomes. The FURCA trial aimed to investigate the effect of patient-led follow-up on HRQoL and symptom burden 3 years after surgery. METHODS: RC patients from four Danish centres were randomised 1:1 to intervention (patient-led follow-up with patient education and self-referral to a specialist nurse) or control (standard follow-up with five routine doctor visits). Patients in both groups had a computed tomography (CT) at 1 and 3 years. The primary outcome (HRQoL) was assessed by the Functional Assessment of Cancer Therapy - colorectal (FACT-C) score (Ward et al. in Qual Life Res. 8(3):181-95, 18). Secondary outcomes were functional measures, patient involvement and satisfaction and cancer recurrence at 3 years. RESULTS: From Feb 2016 to Aug 2018, 336 patients were included of whom 248 completed 3 years of follow-up. Between-group differences were found neither for the primary endpoint, nor for functional outcomes. The recurrence rate did not differ between the groups. Patient involvement and satisfaction were higher in the intervention group with statistical significance in almost half of the items. CONCLUSIONS: We found no effect on HRQoL and symptom burden from patient-led follow-up, although it may improve patient-perceived involvement and satisfaction. IMPLICATIONS FOR CANCER SURVIVORS: The findings in this study suggest that patient-led follow-up is a more tailored approach to meet cancer survivors' needs and might improve their ability to cope with survivorship.

RESUMO
STUDY OBJECTIVES: Obstructive sleep apnea (OSA) has been associated with more severe acute coronavirus disease-2019 (COVID-19) outcomes. We assessed OSA as a potential risk factor for Post-Acute Sequelae of SARS-CoV-2 (PASC). METHODS: We assessed the impact of preexisting OSA on the risk for probable PASC in adults and children using electronic health record data from multiple research networks. Three research networks within the REsearching COVID to Enhance Recovery initiative (PCORnet Adult, PCORnet Pediatric, and the National COVID Cohort Collaborative [N3C]) employed a harmonized analytic approach to examine the risk of probable PASC in COVID-19-positive patients with and without a diagnosis of OSA prior to pandemic onset. Unadjusted odds ratios (ORs) were calculated as well as ORs adjusted for age group, sex, race/ethnicity, hospitalization status, obesity, and preexisting comorbidities. RESULTS: Across networks, the unadjusted OR for probable PASC associated with a preexisting OSA diagnosis in adults and children ranged from 1.41 to 3.93. Adjusted analyses found an attenuated association that remained significant among adults only. Multiple sensitivity analyses with expanded inclusion criteria and covariates yielded results consistent with the primary analysis. CONCLUSIONS: Adults with preexisting OSA were found to have significantly elevated odds of probable PASC. This finding was consistent across data sources, approaches for identifying COVID-19-positive patients, and definitions of PASC. Patients with OSA may be at elevated risk for PASC after SARS-CoV-2 infection and should be monitored for post-acute sequelae.

INTRODUCTION: Orbital mucosa-associated lymphoid tissue (MALT) lymphoma, which are rare and indolent, often present at an early stage. We report the efficacy and safety outcomes of treatment in these patients. METHODS: We analyzed adult patients with stage IE or IIE orbital MALT lymphoma between 1999 and 2017 treated at our institute. We assessed local control (LC) rates, overall survival (OS), relapse-free survival (RFS) using Kaplan Meier method and the incidence of late toxicities. RESULTS: Seventy patients were analyzed for clinical outcomes. The median age at diagnosis was 52 years (IQR-45-62 years). Radiotherapy was offered to 97% of patients and the dose ranged from 36 to 45 Gy. Chemotherapy was administered in 5(7.1%) patients. Relapse occurred in 8 patients (local: 2, distant: 6). At a median follow-up of 101 months (IQR-47-146 months), the median OS and RFS was not reached. 8-year OS, RFS and LC rates were 96.5%, 88.5%, 96.7% respectively. Univariate analysis showed age ≤60 years and lacrimal involvement significantly correlated with better OS (P = .01 and .04, respectively). Cataract was the most common sequelae observed in 31 patients (44.3%). CONCLUSION: Moderate doses of radiotherapy are curative in early-stage orbital MALT lymphoma with favorable clinical outcomes. Lower doses of radiation can reduce the toxicity further, without compromising efficacy.

This article provides information about late complications of retinopathy of prematurity (ROP), especially seen in adolescence and adulthood. The majority of ROP patients recover without complications and treatment, but severe ROP cases should be properly treated. Both prematurity itself and the treatment of ROP cause some changes in the anterior (refractive changes, cataract, and glaucoma) and posterior segments (tractional, rhegmatogenous and exudative retinal detachment, vitreous hemorrhage, etc.,) of the eye and predispose to significant lifelong complications. Awareness of these late complications can minimize severe vision loss with proper follow-up and appropriate treatment. Therefore, life-long ophthalmological follow-up is mandatory in all prematures with the diagnosis of ROP.
RESUMO
INTRODUCTION: One of the most feared side effects of radiotherapy (RT) in the setting of breast cancer (BC) patients is cardiac toxicity. This side effect can jeopardize the quality of life (QoL) of long-term survivors. The impact of modern techniques of RT such as deep inspiration breath hold (DIBH) have dramatically changed this setting. We report and discuss the results of the literature overview of this paper. MATERIALS AND METHODS: Literature references were obtained with a PubMed query, hand searching, and clinicaltrials.gov. RESULTS: We reported and discussed the toxicity of RT and the improvements due to the modern techniques in the setting of BC patients. CONCLUSIONS: BC patients often have a long life expectancy, thus the RT should aim at limiting toxicities and at the same time maintaining the same high cure rates. Further studies are needed to evaluate the risk-benefit ratio to identify patients at higher risk and to tailor the treatment choices.

Ependymomas are the third most-frequent pediatric brain tumors. To prevent local recurrence, the resection site should be irradiated. Compared to photon radiation treatment, proton therapy often achieves even better results regarding target coverage and organ-sparing. Due to their physical properties, helium ions could further reduce side effects, providing better protection of healthy tissue despite similar target coverage. In our in silico study, 15 pediatric ependymoma patients were considered. All patients underwent adjuvant radiotherapeutic treatment with active-scanned protons at Heidelberg Ion Beam Therapy Center (HIT). Both helium ion and highly conformal IMRT plans were calculated to evaluate the potential dosimetric advantage of ion beam therapy compared to the current state-of-the-art photon-based treatments. To estimate the potential clinical benefit of helium ions, normal tissue complication probabilities (NTCP) were calculated. Target coverage was comparable in all three modalities. As expected, the integral dose absorbed by healthy brain tissue could be significantly reduced with protons by up to -48% vs. IMRT. Even compared to actively scanned protons, relative dose reductions for critical neuronal structures of up to another -39% were achieved when using helium ions. The dose distribution of helium ions is significantly superior when compared to proton therapy and IMRT due to the improved sparing of OAR. In fact, previous studies could clearly demonstrate that the dosimetric advantage of protons translates into a measurable clinical benefit for pediatric patients with brain tumors. Given the dose-response relationship of critical organs at risk combined with NTCP calculation, the results of our study provide a strong rationale that the use of helium ions has the potential to even further reduce the risk for treatment related sequelae.
