Exploring Expressions of Possible Selves with High School and College Students with Learning Disabilities

In this article, we explore a program designed to engage high school and college students with learning disabilities (LD) in conversations about their hopes, expectations, and fears for the future. We explore the mindset of students by focusing on their self-identified passions for life and sense of strengths and limitations. We found that males and females differed in goals related to Academics, Work Ethic, Degree Specific Statements, and Money and Finances. For example, females emphasized “Academic Goals” more frequently than males and focused on topics such as GPA and work ethic in school. However, males made more “Degree Specific Statements” than females, more often emphasizing the desire to be financially stable or have a career with a large income. These differences suggest that college transition staff may want to focus on goals identified by male and female students with LD as a way to be more responsive to student self-identified goals

Sensory nerve transfers in the upper limb after peripheral nerve injury:a scoping review

Nerve transfer for motor nerve paralysis is an established technique for treating complex nerve injuries. However, nerve transfer for sensory reconstruction has not been widely used, and published research on this topic is limited compared to motor nerve transfer. The indications and outcomes of nerve transfer for the restoration of sensory function remain unproven. This scoping review examines the indications, outcomes and complications of sensory nerve transfer. In total, 22 studies were included; the major finding is that distal sensory nerve transfers are more successful than proximal ones in succeeding protective sensation. Although the risk of extension of the sensory deficit with donor site loss and morbidity from neuromas remain a barrier to wider adoption, these complications were not reported in the review. Further, the scarcity of studies and small patient series limit the ability to determine sensory nerve transfer success. However, sensory restoration remains an opportunity for surgeons to pursue.</p

Educating Future Generations of Surgeons across Borders:Novel Global Linked Hybrid Live Cadaveric Peripheral Nerve Surgical Training Course

Background: This study aimed to evaluate a novel, multi-site, technology-facilitated education and training course in peripheral nerve surgery. The program was developed to address the training gaps in this specialized field by integrating a structured curriculum, high-fidelity cadaveric dissection, and surgical simulation with real-time expert guidance. Methods: A collaboration between the Global Nerve Foundation and Esser Masterclass facilitated the program, which was conducted across three international sites. The curriculum was developed by a panel of experienced peripheral nerve surgeons and included both text-based and multimedia resources. Participants’ knowledge and skills were assessed using pre- and postcourse questionnaires. Results: A total of 73 participants from 26 countries enrolled and consented for data usage for research purposes. The professional background was diverse, including hand surgeons, plastic surgeons, orthopedic surgeons, and neurosurgeons. Participants reported significant improvements in knowledge and skills across all covered topics (p &lt; 0.001). The course received a 100% recommendation rate, and 88% confirmed that it met their educational objectives. Conclusions: This study underscores the potential of technology-enabled, collaborative expert-led training programs in overcoming geographical and logistical barriers, setting a new standard for globally accessible, high-quality surgical training. It highlights the practical and logistical challenges of multi-site training, such as time zone differences and participant fatigue. It also provides practical insights for future medical educational endeavors, particularly those that aim to be comprehensive, international, and technologically facilitated.</p

Cytoprotection by Amifostine during Autologous Stem Cell Transplantation for Advanced Refractory Hematologic Malignancies

Abstract This study evaluated whether amifostine protects against mucositis and other toxicities in patients with advanced, refractory, or recurrent hematologic malignancies undergoing high-dose chemotherapy and total body irradiation. Thirty-five patients (20 with non-Hodgkin lymphoma, 12 with Hodgkin disease, and 3 with acute myelogenous leukemia) who underwent autologous stem cell transplantation were conditioned with total body irradiation 2 Gy twice daily on days −8 through −6; cyclophosphamide 6 g/m2, etoposide 1.8 g/m2, and carboplatin 1 g/m2 on days −5 through −3; and amifostine 500 mg/m2 on days −8 through −2. Prior institutional experience in patients treated without amifostine was used as a historical comparison (no-amifostine group). Severe mucositis occurred in 14 (40%) of 35 patients in the amifostine group, compared with 33 (94%) of 35 in the no-amifostine group (P < .0001). Total parenteral nutrition was used by 4 (11%) of 35 amifostine-treated patients and 34 (97%) of 35 no-amifostine patients (P < .0001). The median duration of narcotic use decreased from 15.5 days with no amifostine to 11 days with amifostine (P = .002). Granulocyte and platelet engraftment times were similar. Prospective trials with innovative designs and clearly defined stopping rules are warranted to confirm whether amifostine reduces the toxicities of a myelosuppressive conditioning regimen before autologous stem cell transplantation without compromising therapeutic response

Phase I Trial of Nanoparticle Albumin-Bound Paclitaxel in Combination with Gemcitabine in Patients with Thoracic Malignancies

Nab-paclitaxel has a different toxicity profile than solvent-based paclitaxel including a lower rate of severe neutropenia. This trial was designed to determine the maximum tolerated dose and dose limiting toxicities (DLT) of nab-paclitaxel in combination with gemcitabine

FAK overexpression and p53 mutations are highly correlated in human breast cancer

Focal Adhesion Kinase (FAK) is overexpressed in a number of tumors, including breast cancer. Another marker of breast cancer tumorigenesis is the tumor suppressor gene p53 that is frequently mutated in breast cancer. In the present study, our aim was to find a correlation between FAK overexpression, p53 expression and mutation status in a population-based series of invasive breast cancer tumors from the Carolina Breast Cancer Study. Immunohistochemical analyses of 622 breast cancer tumors revealed that expression of FAK and p53 were highly correlated (P = 0.0002) and FAK positive tumors were 1.8 times more likely to be p53 positive compared to FAK negative tumors [odds ratio (OR) = 1.8; 95% Confidence Interval (CI) 1.2 – 2.8, adjusted for age, race and stage at diagnosis]. Tumors positive for p53 expression showed higher intensity of FAK staining (P<0.0001) and higher percent of FAK positive staining (P<0.0005). From the same study, we evaluated 596 breast tumors for mutations in the p53 gene, using SSCP (single strand conformational polymorphism) and sequencing. Statistical analyses were performed to determine the correlation between p53 mutation status and FAK expression in these tumors. We found that FAK expression and p53 mutation were positively correlated (P<0.0001) and FAK positive tumors were 2.5 times more likely to be p53 mutation positive compared to FAK negative tumors [adjusted OR = 2.5, 95% CI 1.6–3.9]. This is the first analysis demonstrating a high correlation between FAK expression and p53 mutations in a population-based series of breast tumors

Lock-in thermography as a rapid and reproducible thermal characterization method for magnetic nanoparticles

Lock-in thermography (LIT) is a sensitive imaging technique generally used in engineering and materials science (e.g. detecting defects in composite materials). However, it has recently been expanded for investigating the heating power of nanomaterials, such as superparamagnetic iron oxide nanoparticles (SPIONs). Here we implement LIT as a rapid and reproducible method that can evaluate the heating potential of various sizes of SPIONs under an alternating magnetic field (AMF), as well as the limits of detection for each particle size. SPIONs were synthesized via thermal decomposition and stabilized in water via a ligand transfer process. Thermographic measurements of SPIONs were made by stimulating particles of varying sizes and increasing concentrations under an AMF. Furthermore, a commercially available SPION sample was included as an external reference. While the size dependent heating efficiency of SPIONs has been previously described, our objective was to probe the sensitivity limits of LIT. For certain size regimes it was possible to detect signals at concentrations as low as 0.1 mg Fe/mL. Measuring at different concentrations enabled a linear regression analysis and extrapolation of the limit of detection for different size nanoparticles

The triple negative paradox: Primary tumor chemosensitivity of breast cancer subtypes

"Purpose: Gene expression analysis identifies several breast cancer subtypes. We examined the relationship of neoadjuvant chemotherapy response to outcome among these breast cancer subtypes. Experimental Design: We used immunohistochemical profiles [human epidermal growth factor receptor 2–positive (HER2+)/hormone receptor–negative for HER2+/estrogen receptor–negative (ER−), hormone receptor and HER2− for basal-like, hormone receptor–positive for luminal] to subtype a prospectively maintained data set of patients with breast cancer treated with neoadjuvant anthracycline-based (doxorubicin plus cyclophosphamide, AC) chemotherapy. We analyzed each subtype for clinical and pathologic response to neoadjuvant chemotherapy and examined the relationship of response to distant disease–free survival and overall survival. Results: Of the 107 patients tested, 34 (32%) were basal-like, 11 (10%) were HER2+/ER−, and 62 (58%) were luminal. After neoadjuvant AC, 75% received subsequent chemotherapy and all received endocrine therapy if hormone receptor–positive. The chemotherapy regimen and pretreatment stage did not differ by subtype. Clinical response to AC was higher among the HER2+/ER− (70%) and basal-like (85%) than the luminal subtypes (47%; P less than 0.0001). Pathologic complete response occurred in 36% of HER2+/ER−, 27% of basal-like, and 7% of luminal subtypes (P = 0.01). Despite initial chemosensitivity, patients with the basal-like and HER2+/ER− subtypes had worse distant disease–free survival (P = 0.04) and overall survival (P = 0.02) than those with the luminal subtypes. Regardless of subtype, only 2 of 17 patients with pathologic complete response relapsed. The worse outcome among basal-like and HER+/ER− subtypes was due to higher relapse among those with residual disease (P = 0.003). Conclusions: Basal-like and HER2+/ER− subtypes are more sensitive to anthracycline-based neoadjuvant chemotherapy than luminal breast cancers. Patients that had pathologic complete response to chemotherapy had a good prognosis regardless of subtype. The poorer prognosis of basal-like and HER2+/ER− breast cancers could be explained by a higher likelihood of relapse in those patients in whom pathologic complete response was not achieved.
