Abstract

The advent of immune-checkpoint inhibitors (ICI) in modern oncology has significantly improved survival in several cancer settings. A subgroup of women with breast cancer (BC) has immunogenic infiltration of lymphocytes with expression of programmed death-ligand 1 (PD-L1). These patients may potentially benefit from ICI targeting the programmed death 1 (PD-1)/PD-L1 signaling axis. The use of tumor-infiltrating lymphocytes (TILs) as predictive and prognostic biomarkers has been under intense examination. Emerging data suggest that TILs are associated with response to both cytotoxic treatments and immunotherapy, particularly for patients with triple-negative BC. In this review from The International Immuno-Oncology Biomarker Working Group, we discuss (a) the biological understanding of TILs, (b) their analytical and clinical validity and efforts toward the clinical utility in BC, and (c) the current status of PD-L1 and TIL testing across different continents, including experiences from low-to-middle-income countries, incorporating also the view of a patient advocate. This information will help set the stage for future approaches to optimize the understanding and clinical utilization of TIL analysis in patients with BC. ispartof: NPJ BREAST CANCER vol:7 issue:1 ispartof: location:United States status: published

Abstract

Stromal tumor-infiltrating lymphocytes (sTILs) are important prognostic and predictive biomarkers in triple-negative (TNBC) and HER2-positive breast cancer. Incorporating sTILs into clinical practice necessitates reproducible assessment. Previously developed standardized scoring guidelines have been widely embraced by the clinical and research communities. We evaluated sources of variability in sTIL assessment by pathologists in three previous sTIL ring studies. We identify common challenges and evaluate impact of discrepancies on outcome estimates in early TNBC using a newly-developed prognostic tool. Discordant sTIL assessment is driven by heterogeneity in lymphocyte distribution. Additional factors include: technical slide-related issues; scoring outside the tumor boundary; tumors with minimal assessable stroma; including lymphocytes associated with other structures; and including other inflammatory cells.

Abstract

Stromal tumor-infiltrating lymphocytes (sTILs) are important prognostic and predictive biomarkers in triple-negative (TNBC) and HER2-positive breast cancer. Incorporating sTILs into clinical practice necessitates reproducible assessment. Previously developed standardized scoring guidelines have been widely embraced by the clinical and research communities. We evaluated sources of variability in sTIL assessment by pathologists in three previous sTIL ring studies. We identify common challenges and evaluate impact of discrepancies on outcome estimates in early TNBC using a newly-developed prognostic tool. Discordant sTIL assessment is driven by heterogeneity in lymphocyte distribution. Additional factors include: technical slide-related issues; scoring outside the tumor boundary; tumors with minimal assessable stroma; including lymphocytes associated with other structures; and including other inflammatory cells. Small variations in sTIL assessment modestly alter risk estimation in early TNBC but have the potential to affect treatment selection if cutpoints are employed. Scoring and averaging multiple areas, as well as use of reference images, improve consistency of sTIL evaluation. Moreover, to assist in avoiding the pitfalls identified in this analysis, we developed an educational resource available at www.tilsinbreastcancer.org/pitfalls.

Abstract

Purpose: To analyse change in distance between the humeral head and the glenoid fossa during traction in the maximally loose-packed position (MLPP) and the maximally closed-packed position (MCPP) under standardized conditions.Subjects: Six healthy subjects (three male and three female) with a mean age of 40.5 years, volunteered to participate in this study.Materials and methods: Subjects were placed with the right shoulder in a modified shoulder brace (Otto Bock Armabduktions-Orthese in Modular Bauweise((R))) in 45degrees abduction in the plane of the scapula with neutral rotation (MLPP). A standard anterior-posterior radiograph of the glenohumeral joint was made. A 14 kg traction force was applied for 40 s, and a second radiograph was made. The same procedure was repeated with the shoulder placed in the MCPP, which was 90degrees abduction and 90degrees external rotation. A radiologist, blinded for the variable traction or no traction, performed all radiographic measurements. Measurements were made on the same radiographs on two separate occasions (O1 and O2) with a 2-month interval.Results: No significant differences were found in mean distance between the humeral head and the glenoid fossa during traction in the MLPP compared to traction in the MCPP (O1: P = 1.00) and (O2: P = 0.63).Conclusions: Application of a 14 kg force does not result in a significant increase of distance between the humeral head and the glenoid fossa. No significant difference was found between the change in distance of the humeral head and the glenoid fossa after traction in the MLPP compared to traction in the MCPP.

Abstract

The purpose of this case study is to illustrate how attachment theory can help us lead to a therapeutic hospitalization of a borderline adolescent. We describe the borderline psychopathology during adolescence followed by its relationship to attachment disorders, one of major etiologies most specific to borderline disorder. We then go over the clinical situation of Alice relying on attachment theories so that the stay is containing and enables a good excitation barrier system. This guides us towards a therapeutic project avoiding banalisation and symptomatic outbidding. © 2010 Elsevier Masson SAS., SCOPUS: ar.j, info:eu-repo/semantics/published

Abstract

Background: We aimed to determine the timeliness of rabies post-exposure prophylaxis (PEP) and the proportion of individuals with an adequate antibody response post-PEP among those attending the Belgian national reference center., Methods: Retrospective analysis of patient records who attended our center from 2018 to 2023. Delay was defined as rabies immunoglobulin (RIG) and vaccine initiation beyond 2 calendar days after exposure. Antibodies were measured by rapid fluorescent focus inhibition test (RFFIT) after PEP in high-risk exposures. A titer ≥0.5 IU/ml was considered adequate., Results: We reviewed 317 patient records. Among individuals with inland exposure (n = 103), 85 % timely received PEP. Among travelers exposed abroad (n = 214), administration of RIG and vaccine initiation were timely in 30 % and 50 % of cases, respectively. An adequate antibody response was detected in 99.5 % (195/196) individuals., Conclusion: Substantial PEP delays among travelers were observed. The robust antibody responses suggest that routine serological follow-up is not necessary for all patients., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Abstract

A 35-year-old woman underwent bilateral lung transplantation for primary ciliary dyskinesia and developed vascular tumors over a slow time course. Initial presentation of non-specific vascular tumors in the lungs and liver for up to 6 years after transplantation evolved toward bilateral ovarian angiosarcoma. Tumor analysis by haplotyping and human leukocyte antigen typing showed mixed donor chimerism, proving donor origin of the tumoral lesions. In retrospect, the donor became brain dead following neurosurgical complications for a previously biopsy-proven cerebral hemangioma, which is believed to have been a precursor lesion of the vascular malignancy in the recipient. Donor-transmitted tumors should always be suspected in solid organ transplant recipients in case of uncommon disease course or histology, and proper tissue-based diagnosis using sensitive techniques should be pursued., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Bos, Daniëls, Michaux, Vanden Bempt, Vermeer, Woei-A-Jin, Schöffski, Weynand, Sciot, Declercq, Ceulemans, Godinas, Verleden, Van Raemdonck, Dupont, Vos and the Leuven Lung Transplant Group.)

12. Point-of-Care Biomarkers to Guide Antibiotic Prescription for Acute Febrile Illness in Sub-Saharan Africa: Promises and Caveats.

Author

van Griensven J, Cnops L, De Weggheleire A, Declercq S, and Bottieau E

Abstract

Empiric malaria treatment in Sub-Saharan Africa has significantly decreased with the scaling-up of malaria rapid diagnostic tests; this coincided with a pronounced increase in empiric antibiotic prescriptions. In high-income countries, guidance for antibiotic prescriptions using biomarkers such as C-reactive protein (CRP) and procalcitonin (PCT) has reduced antibiotic use while safe-guarding patient safety. Importantly, several low-cost point-of-care CRP/PCT tests are currently available. However, only a few studies on the role of CRP/PCT in differentiating bacterial vs viral infections in acute febrile illness have been conducted in Sub-Saharan Africa. Studies from Central and West Africa (most of which is malaria-endemic) are particularly scarce, and only 1 has included adults. The evidence base for point-of-care use of CRP/PCT biomarkers in acute fever in Sub-Saharan Africa should be urgently built. Before engaging in clinical trials to assess clinical impact, pilot studies should be conducted to address key knowledge gaps including recommended CRP/PCT cutoff values and the effect of malaria coinfection., (© The Author(s) 2020.

13. Placental Findings in Lysosomal Storage Disease Diagnosis: A Case Report of Galactosialidosis.

Author

Libbrecht S, Eyskens F, Declercq S, and Colpaert C

Abstract

Introduction . Lysosomal storage disorders (LSDs) are rare diseases with more than 50 different entities described today. The spectrum of phenotypes varies from severe to lethal and early-onset disease to mild and late onset. Recognition of the clinical signs and diagnostic workup is challenging and requires expertise. Diagnosis relies on finding abnormal metabolites in urine and serum followed by further enzymatic or molecular analysis. Routine histological examination of the foetal and placental tissues frequently shows vacuolisation, providing a readily available important clue to the diagnosis. Case Report . A third child of consanguineal parents showed several dysmorphic features and a complicated neonatal period with eventual demise in the early postneonatal period due to respiratory failure. An LSD was suspected based on clinical presentation, urine metabolite excretion, skeletal radiograph, and vacuolisation in lymphocytes and placental tissues on, respectively, blood smear and routine histological examination. Homozygosity mapping favoured galactosialidosis. The diagnosis was confirmed by massive parallel sequencing, revealing a single nucleotide variation in the CTSA gene (c.265A>C, p.Ser89Arg). Discussion . Histological placental examination may be either the first clue or complimentary evidence in recognizing LSDs. It is important to recognize these clues as it may prompt further investigation and facilitate earlier recognition of the disease., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2020 Sasha Libbrecht et al.)

Abstract

Background: Pediatric germ cell tumors account for approximately 3.5 % of all childhood cancers for children under the age of 15 years. Up to one-third are extragonadal neoplasms. Germ cell tumors are a heterogeneous group of malignant tumors with a wide variety of histopathological features. Yolk sac tumor is the predominant variant in newborns and younger children. We report for the first time, the presentation of a primary yolk sac tumor in the abdominal wall of a small child., Case Presentation: An 18-month-old white girl underwent resection of a small, round subcutaneous lump (1.5×1.3×0.8 cm) of the abdominal wall in her right hypochondriac region. The histopathology was compatible with yolk sac tumor. Her alpha-fetoprotein was initially elevated but normalized after the resection. Magnetic resonance imaging of her abdomen was normal. The surgeon decided to observe and follow her alpha-fetoprotein level closely. One year after resection a local recurrence appeared and her alpha-fetoprotein rose to 58 ng/mL. The surgeon performed a wide resection of the lesion with normalization of her alpha-fetoprotein. Follow-up consisted of measuring alpha-fetoprotein, clinical evaluation, and abdominal ultrasound., Conclusions: Clinicians should be aware that a yolk sac tumor can present in an unusual extragonadal place, for example in this case it was subcutaneous. In some cases, conservative treatment can be carried out with careful monitoring of the patient and their alpha-fetoprotein.

Abstract

Meckel's diverticulum (MD) is a persistent remnant of the vitelointestinal duct and is present in 2% of population [1]. It is the most common congenital malformation of the gastrointestinal tract. It can present clinically as haemorrhage, diverticulitis, intussusception, chronic ulceration, intestinal obstruction and perforation. Complicated presentation, especially bleeding, tends to be more common in the paediatric group, whereas intestinal obstruction is more common in adults [2]. Patients with a perforation of Meckel's diverticulum by an enterolith are rare and may present with right iliac fossa pain, which mimics acute appendicitis., (Copyright © 2015 The Authors.

Abstract

Psoriasis is a chronic, proliferative, and inflammatory skin disease affecting 2-3% of the population and is characterized by red plaques with white scales. Psoriasis is a disease that can affect many aspects of professional and social life. Currently, several treatments are available to help control psoriasis such as methotrexate, ciclosporin, and oral retinoids. However, the available treatments are only able to relieve the symptoms and lives of individuals. The discovery of new immunological factors and a better understanding of psoriasis have turned to the use of immunological pathways and could develop new biological drugs against specific immunological elements that cause psoriasis. Biological drugs are less toxic to the body and more effective than traditional therapies. Thus, they should improve the quality of life of patients with psoriasis. This review describes new psoriasis treatments, which are on the market or currently in clinical trials that are being used to treat moderate-to-severe plaque psoriasis. In addition, this paper describes the characteristics and mechanisms in detail. In general, biological drugs are well tolerated and appear to be an effective alternative to conventional therapies. However, their effectiveness and long-term side effects need to be further researched.
