[Translated article] Multicenter Analysis of the Surgical Management and Adjuvant Therapy of Patients With Melanoma and a Positive Sentinel Lymph Node Biopsy.

Introduction: Complete lymph node dissection (CLND) was the standard practice for patients with melanoma and a positive sentinel lymph node biopsy (SLNB) until the results of two clinical trials published in 2016 and 2017 demonstrated that it did not improve melanoma-specific survival (MSS). However, it continues to be performed in some scenarios. No studies have ever been published on lymph node management after a positive SLNB in the routine clinical practice in our setting.

Technological applications to enhance independence in daily activities for older adults: a systematic review.

Introduction: Monitoring daily activities in older adults using sensor technologies has grown significantly over the past two decades, evolving from simple tools to advanced systems that integrate Artificial Intelligence (AI) and the Internet of Things (IoT) for predictive monitoring. Despite these advances, there is still a need for a comprehensive review that addresses both technological progress and its impact on autonomous aging.

Objective: To conduct a systematic review of sensor technologies used to monitor the daily activities of independent older adults, focusing on sensor types, applications, usage contexts, and their evolution over time.

Examining the influence of self-care practices on brain activity in healthy older adults.

Introduction: Studies on the aging brain often occur in active settings, but comparatively few investigate brain activity in resting states. However, exploring brain activity in a resting state offers valuable insights into spontaneous neural processes unaffected by task-specific influences. Objective: To investigate the relationship between self-care practices, cognitive function, and patterns of brain activity in healthy older adults, taking into account predictions from aging brain models.

Interobserver Variability in the Histopathological Evaluation of Melanoma: Analysis of 60 Cases.

Introduction: Since the field of dermatopathology is not an exact science, it is subject to personal subjectivity, which sometimes causes disagreements on the diagnosis and assessment of some histological features. In the case of melanoma, some variables such as regression are associated with low interobserver agreement. On the contrary, other variables such as the measurement of Breslow thickness show high reproducibility.

Combined Merkel Cell Carcinoma and Squamous Cell Carcinoma: A Systematic Review.

Combined Merkel cell carcinoma (MCC) and squamous cell carcinoma (SCC) have classically been regarded as more aggressive than conventional, pure, Merkel cell polyomavirus (MCPyV)-positive MCC. It is still unknown whether combined MCC and SCC are more aggressive than pure, MCPyV-negative MCC, and the origin of both the SCC and MCC elements of these combined tumors has not been elucidated. The main objective of this systematic review was to assess whether combined MCC and SCC tumors are associated with a worse prognosis than pure MCC; the secondary goals were the characterization of the clinical and histopathological features of these combined neoplasms.

Clinical, histological, and molecular differences in melanoma due to different TERT promoter mutations subtypes. A retrospective cross-sectional study in 684 melanoma patients.

Differences in survival according to the pTERT mutation subtypes (-124C > T, -146C > T, and tandem -138_139CC > TT) have been observed. The present study aimed to describe the clinical as the histopathological and molecular cutaneous melanoma features according to the presence of the three most prevalent pTERT mutation subtypes (-124C > T, -146C > T, and tandem -138_139CC > TT). A retrospective cross-sectional study including 684 patients was designed, and a Partial Least-Squares Discriminant Analysis (PLS-DA) was performed.

Nodular Type but Not Vitamin D Levels Increases the Risk of Second Primary Cancers in Melanoma Patients: An Observational Study of 663 Patients.

Background: Vitamin D deficiency associates with the risk of developing many diseases, including cancer. At the molecular level, vitamin D appears to have an antineoplastic effect. However, the role of vitamin D deficiency in cancer pathogenesis remains unelucidated and numerous studies have resulted in discordant results.

Molecular Profile of Subungual Melanoma: A MelaNostrum Consortium Study of 68 Cases Reporting BRAF, NRAS, KIT, and TERT Promoter Status.

Background: Subungual melanoma (SM) is an unusual type of melanocytic tumor affecting the nail apparatus. The mutational prevalence of the most prominently mutated genes in melanoma has been reported in small cohorts of SM, with unclear conclusions on whether SM is different from the rest of melanomas arising in acral locations or not. Hence, the molecular profile of a large series of SM is yet to be described.

Self-care interventions of community-dwelling older adults: a systematic review and meta-analysis.

Introduction: The current notion of "care in old age" should be reconceptualized in the ageing societies of the 21st century. Currently, "being old" means that one is actively involved in their care and has the desire to retain control and independence.

Objective: Understand and analyze the efficacy of interventions in the physical and psychological self-care practices of healthy community-dwelling older people.

Nodular type but not vitamin D levels increases the risk of second primary cancers in melanoma patients: An observational study of 663 patients.

Background: Vitamin D deficiency associates with the risk of developing many diseases, including cancer. At the molecular level, vitamin D appears to have an antineoplastic effect. However, the role of vitamin D deficiency in cancer pathogenesis remains unelucidated and numerous studies have resulted in discordant results.

High- and intermediate-risk susceptibility variants in melanoma families from the Mediterranean area: A multicentre cohort from the MelaNostrum Consortium.

Background: Most of large epidemiological studies on melanoma susceptibility have been conducted on fair skinned individuals (US, Australia and Northern Europe), while Southern European populations, characterized by high UV exposure and dark-skinned individuals, are underrepresented.

Objectives: We report a comprehensive pooled analysis of established high- and intermediate-penetrance genetic variants and clinical characteristics of Mediterranean melanoma families from the MelaNostrum Consortium.

Methods: Pooled epidemiological, clinical and genetic (CDKN2A, CDK4, ACD, BAP1, POT1, TERT, and TERF2IP and MC1R genes) retrospective data of melanoma families, collected within the MelaNostrum Consortium in Greece, Italy and Spain, were analysed.

Topographical and Chronological Analysis of Thin Cutaneous Melanoma's Progressions: A Multicentric Study.

A great portion of cutaneous melanoma's diagnoses nowadays is attributed to thin tumors with up to 1 mm in Breslow thickness (hereafter thin CMs), which occasionally metastasize. The objective of this study was to identify thin CM's metastatic patterns from a topographical and chronological standpoint. A total of 204 cases of metastatic thin CMs from five specialized centers were included in the study, and corresponding data were collected (clinical, epidemiological, histopathological information of primary tumor and the number, anatomical site, and time intervals of their progressions).

Electrophysiological connectivity of logical deduction: Early cortical MEG study.

Complex human reasoning involves minimal abilities to extract conclusions implied in the available information. These abilities are considered "deductive" because they exemplify certain abstract relations among propositions or probabilities called deductive arguments. However, the electrophysiological dynamics which supports such complex cognitive processes has not been addressed yet.

Electrical analysis of logical complexity: an exploratory eeg study of logically valid/invalid deducive inference.

Introduction: Logically valid deductive arguments are clear examples of abstract recursive computational procedures on propositions or on probabilities. However, it is not known if the cortical time-consuming inferential processes in which logical arguments are eventually realized in the brain are in fact physically different from other kinds of inferential processes.

Methods: In order to determine whether an electrical EEG discernible pattern of logical deduction exists or not, a new experimental paradigm is proposed contrasting logically valid and invalid inferences with exactly the same content (same premises and same relational variables) and distinct logical complexity (propositional truth-functional operators).

Practices of Self-Care in Healthy Old Age: A Field Study.

Unlabelled: Two competing psychological approaches for how to care for oneself to stay healthy in old age have coexisted and dominated the scientific literature.

Objective: Identify the self-care practices of healthy older adults and establish the relationship between these practices and the cognitive processes involved.

Method: 105 healthy older people (83.

Lymphovascular Invasion and High Mitotic Count Are Associated With Increased Risk of Recurrence in Pleomorphic Dermal Sarcoma.

Background And Objective: Atypical fibroxanthoma and pleomorphic dermal sarcoma (PDS) are rare mesenchymal tumors. Due to the low incidence of PDS and a historically confusing nomenclature, little is known about the true aggressiveness of this tumor. The aim of this study was to investigate clinical and histologic risk factors for recurrence in PDS.

Melanoma arising in plaque-type blue nevus and dermal melanocytosis: Diagnostic and prognostic value of BAP1.

Melanoma arising in blue nevus, also known as melanoma ex blue nevus, is a specific form of melanoma whose genetic profile is different to that of other cutaneous melanomas and surprisingly similar to that of uveal melanoma. Although melanoma ex blue nevus can appear de novo, it usually arises in a preexisting blue nevus or dermal melanocytosis. Not all nodular lesions arising in association with blue nevus or dermal melanocytosis are melanomas, however, and because clinical and histologic findings may be insufficient for a definitive diagnosis, additional studies such as comparative genomic hybridization are important.

Update on Lentigo Maligna: Diagnostic Signs and Treatment.

Lentigo maligna is an in situ cutaneous melanoma that arises in sun-damaged skin. Its most common presentation is a progressive, slow-growing, irregularly pigmented spot on the face of older patients. Although the exact percentage of Lentigo maligna that progresses to invasive tumors is unknown, it is thought to lie between 2% and 5%.

Tumor Microenvironment and Its Clinicopathologic and Prognostic Association in Cutaneous and Noncutaneous Angiosarcomas.

Objectives: We explored features of the angiosarcoma (AS) tumor microenvironment to discover subtypes that may respond to immunotherapy.

Methods: Thirty-two ASs were included. Tumors were studied by histology, immunohistochemistry (IHC), and gene expression profile using the HTG EdgeSeq Precision Immuno-Oncology Assay.

Trichoepithelioma on the Finger: A Rare Location and Dermoscopic-Histopathologic Correlation.

Trichoepithelioma is a benign adnexal neoplasm of follicular germinative cells, with bulbs, papillae, and sheaths of perifollicular connective tissue as signs of follicular differentiation. Accordingly, trichoepithelioma may arise in any hair-bearing location, mostly on the face. That is why trichoepithelioma cannot appear in glabrous skin, and, although the dorsum of the hands and feet are a hair-bearing area, acral location is exceptional.
