Enhancing Cross-Cultural Competence of Medical and Healthcare Students with the Use of Simulated Patients-A Systematic Review.

Increasing cultural and linguistic diversities of populations have created a challenge for medical educators to provide authentic learning experiences fostering cross-cultural understanding and interprofessional attitudes of students. Simulations with actors portraying patients (commonly referred to as simulated patients) are effective learning modalities to teach students to provide culturally competent care and influence the quality of patient-centered care. The aim of this systematic review was to identify and synthesize available evidence on the use of simulations with simulated patients as a learning intervention to teach cultural competence to the students of healthcare professions. The PubMed, Medline Complete, and CINAHL databases were searched for articles, which resulted in 27 papers being included in the review. Results revealed that engaging students in cross-cultural interactions with patients increases their level of cultural competence, confidence, and learning satisfaction, and therefore, simulations with simulated patients can serve as a powerful reinforcement of cross-cultural education.

Successful Treatment of Large B-Cell Lymphoma in a Child with Compound Heterozygous Mutation in the ATM Gene.

Ataxia-telangiectasia (AT) is a multisystemic neurodegenerative inborn error of immunity (IEI) characterized by DNA repair defect, chromosomal instability, and hypersensitivity to ionizing radiation. Impaired DNA double-strand break repair determines a high risk of developing hematological malignancies, especially lymphoproliferative diseases. Poor response to treatment, excessive chemotherapy toxicities, and the need for avoiding exposure to ionizing radiation make the successful clinical management of patients with AT challenging for oncologists. We describe the favorable outcome of the LBCL with IRF4 rearrangement at stage III in a 7-year-old female patient diagnosed with AT. The patient was treated according to the B-HR arm of the INTER-B-NHL-COP 2010 protocol, including the administration of rituximab, cyclophosphamide, methotrexate, prednisone, etc. She presented excessive treatment toxicities despite individually reduced doses of methotrexate and cyclophosphamide. However, in the MRI there was no significant reduction in pathologic lymph nodes after three immunochemotherapy courses. Therefore, a lymph node biopsy was taken. Its subsequent histopathological examination revealed tuberculosis-like changes, though tuberculosis suspicion was excluded. After two following immunochemotherapy courses, PET-CT confirmed complete remission. From March 2022 onwards, the patient has remained in remission under the care of the outpatient children's oncology clinic.

Clinical use of polyvalent intravenous immunoglobulins during intensive polychemotherapy in children with acute lymphoblastic leukemia.

BACKGROUND: Acute lymphoblastic leukemia (ALL) is seen in almost 30% of cases of cancer among children. Drop in absolute neutrophil count (ANC) and immunosuppression during chemotherapy are causing the significant increase in the risk of other complications, which can lead to prolonged hospitalization, higher costs of therapy and increased mortality. METHODS: The analysis concerned 78 patients treated for ALL at the Department of Pediatric Oncology, Hematology and Transplantology. The indications for the use of immunoglobulins, the regimen of administration, the dose and adverse reactions were analyzed. RESULTS: Intravenous immunoglobulins (IVIGs) were used in 66 (85%) of 78 patients. The standard risk group (SR) was represented by 10 (15%) patients, intermediate (IR) - 29 (44%), and high (HR) - 27 (41%). The most common were 1 and 2-day administrations - 60% and 28%, respectively, of transfusions. The spread of the IVIG doses used ranged from 43 mg to 882 mg/kg body weight. In the SR and IR groups, preparations were transfused at the reinduction stage, while in the HR-consolidation. Among the indications for IVIG, the most common was hypogammaglobulinemia-117 (42%), neutropenia-69 (25%) and infection-62 (22%). During the implementation of 279 patterns of immunoglobulin preparations, 8 (3%) post-transfusion reactions were registered. CONCLUSIONS: The vast majority of ALL patients required immunoglobulin substitution during polychemotherapy. The supply of preparations is safe, however, there are no unambiguous guidelines regarding their dosage.

Parenchyma Sparing Anatomic Liver Resections (Bi- and Uni-Segmentectomies) for Liver Tumours in Children-A Single-Centre Experience.

Purpose: To present a single-centre experience in bi- and uni-segmentectomies for primary liver tumours in children. METHODS: This study included 23 patients that underwent (bi)segmentectomy. There were 15 malignant tumours (hepatoblastoma-13 patients), 7 benign tumours, and 1 calcifying nested stromal epithelial tumour. RESULTS: The median tumour diameter was 52 mm (range 15-170 mm). Bisegmentectomy 2-3 was most frequently performed (seven patients), followed by bisegmentectomy 5-6 (four patients). The median operative time was 225 min (range 95-643 min). Intraoperative complications occurred in two patients-small bowel perforation in one and an injury of the small peripheral bile duct resulting in biloma in the other. The median resection margin in patients with hepatoblastoma was 3 mm (range 1-15 mm). Microscopically negative margin status was achieved in 12 out of 13 patients. There were two recurrences. After a median follow-up time of 38 months (range 12-144 months), all 13 patients with HB were alive with no evidence of disease. Two relapsed patients were alive with no evidence of disease. CONCLUSIONS: From the available literature and data presented here, we propose that (bi)segmentectomy can become a viable surgical option in carefully selected paediatric patients and is sufficient to achieve a cure. Further studies evaluating the impact of parenchymal preservation surgery on surgical and oncological outcome should be conducted with a larger dataset.

'Difficult Conversations with Patients'-A Modified Group Objective Structured Clinical Experience for Medical Students.

This study presents a modified Group Objective Structured Clinical Experience (GOSCE) focused on difficult conversations, in which, due to limited time and financial resources, only some students could actively participate in scenarios. We aimed to evaluate the intervention, including differences between them and observers. The intervention was organized for sixth-year medical students at a Polish medical university. The study protocol assumed a pre-post analysis of students' attitudes and self-efficacy of communication skills and their opinions about the intervention. Complete questionnaire pairs were returned by 126 students. The pre-post analysis revealed a significant improvement in their self-efficacy levels of almost all skills as well as their affective attitudes and belief in outcomes of communication learning. The improvement was significant among both the active participants and observers. It also showed a decrease in the motivation score, significant only in females. Regardless of their roles, students had positive opinions about the course and its particular aspects. The modified GOSCE may be an enjoyable and effective learning experience for students, especially in the light of limited resources. However, changes in their motivation score suggest the necessity to increase the importance of communication learning in the curriculum.

Affective and cognitive components of students' attitudes towards communication learning - validation of the Communication Skills Attitude Scale in a cohort of polish medical students.

BACKGROUND: The Communication Skills Attitude Scale (CSAS) is a recognized tool for assessment of attitudes towards communication learning. In the original version, it consists of 26 items divided on theoretical assumptions into two subscales: Positive and Negative Attitudes Scales. However, the evidence for its structure seems unsatisfactory, and a simple division into positive and negative attitudes may be insufficient to describe attitudes of medical students towards communication learning. Moreover, the existing evidence of the test-retest reliability of the CSAS seems limited. Consequently, this study aimed to provide more evidence on its psychometric properties while validating the CSAS questionnaire in a cohort of Polish medical students. METHODS: The CSAS was translated, adapted into Polish, and validated in a cohort of 389 Polish medical students. Statistical analysis involved, among others, parallel analysis to determine the number of factors, confirmatory factor analysis to compare the proposed model with theory-based ones, and test-retest reliability analysis. RESULTS: Conducted analysis revealed that in the examined population, the CSAS should rather consist of four than two subscales. Proposed four subscales addressed perceived outcomes of communication learning, positive and negative attitudes towards it (affective components), and factors motivating students to learn communication (a cognitive component of attitudes). Results of test-retest reliability were satisfactory for individual items and subscales. CONCLUSIONS: This study presented a valid and reliable version of the Communication Skills Attitude Scale for Polish medical students and confirmed previous assumptions that CSAS may also be appropriate for assessment of affective and cognitive components of attitudes. Future research should, based on Ajzen's Theory of Planned Behavior, make attempts to develop a tool assessing not only attitudes but also subjective norms and perceived behavioral control.

Clinical factors in relapses of Wilms' tumor--results for the Polish Pediatric Solid Tumors Study Group.

BACKGROUND: The risk factors responsible for recurrences of Wilms' tumor (nephroblastoma) are still under discussion. The aim of the study was to analyze the relationship between relapses of Wilms' tumor and the patients' clinical history. MATERIAL AND METHODS: Clinical data from children registered in the Polish Pediatric Solid Tumors Study Group were analyzed. The clinical stages (CS), pathology variants (high risk: HR, intermediate risk: INT, and low risk: LOW) and chemotherapy regimens were correlated with the outcomes. RESULTS: Recurrences developed in 34 out of 288 (11.8%) patients with Wilms' tumor treated in accordance with International Society for Pediatric Oncology 2001 (SIOP 2001) protocols. Of these 34 patients, 11 initially had CS I, seven were at CS II, four were at CS III, 11 were at CS IV and one had CS V. There were eight patients with second recurrences; of these, seven were in the INT risk group and one in the high histological risk group. There was no correlation between age (p=0.256) or gender (p=0.538) and the risk of tumor recurrence. In the study group, seven out of 10 patients with local recurrences are alive; as are 13 out of 22 patients with distant recurrences (p=0.703). Those who died due to disease progression comprised six out of 26 patients with a first recurrence (four HR, two INT), and seven out of eight with a second recurrence (one HR, six INT). CONCLUSIONS: The prognosis after relapse in initially metastatic patients did not differ from that in patients who had primarily localized disease. The pathology variants probably had more significance.
