RESUMEN

BACKGROUND: Mentorship is critical to success in postgraduate science, technology, engineering, math, and medicine (STEMM) settings. As such, the purpose of this study is to comprehensively explore the state of mentorship interventions in postgraduate STEMM settings to identify novel practices and future research directions. The selection criteria for reviewed articles included: 1) published between 2002 and 2022, 2) peer-reviewed, 3) in English, 4) postgraduate mentees, 5) a program where mentorship is a significant, explicit focus, and 6) a description of mentee outcomes related to the mentorship intervention. Overall, 2583 articles were screened, and 109 articles were reviewed. RESULTS: Most postgraduate STEMM mentorship intervention studies lack strong evidence to evaluate the effectiveness of the intervention, with only 5.5% of articles designed as randomized controlled trials. Most mentorship interventions (45.6%) were created for faculty, and few (4%) were for postdoctoral researchers. Also, only 18.8% of interventions focused on underrepresented groups in STEMM. Most interventions (53.7%) prescribed a dyadic structure, and there was more mentorship training for mentors than mentees. CONCLUSION: Overall, these findings identify gaps in mentorship interventions and provide step-by-step guidance for future interventions, including a consideration for underrepresented groups and postdoctoral scholars, robust mentorship training, and more randomized controlled trials.

RESUMEN

In the dermatological spectrum of oncologic manifestations, cutaneous metastases from endometrial carcinoma stand as a rarity, given the tumour's predilection for neighbouring uterine regions. We present an exceptional case of a patient in her mid-50s, whereby an endometrial carcinoma, defying conventional pathways, manifested on the skin and nail of her distal fourth finger, an unusual site for cutaneous metastases, with a specific histology of the primary cancer.

RESUMEN

"Helicopter research" refers to a practice where researchers from wealthier countries conduct studies in lower-income countries with little involvement of local researchers or community members. This practice also occurs domestically. In this Commentary, we outline strategies to curb domestic helicopter research and to foster equity-centered collaborations.

RESUMEN

Many successful researchers in the biomedical sciences have benefitted from mentors and networks earlier in their career. However, early-career researchers from minoritized and underrepresented groups do not have the same access to potential mentors and networks as many of their peers. In this article we describe how 'cold emails' and social media platforms - notably Twitter/X and LinkedIn - can be used to build virtual networks, and stress the need to invest in maintaining networks once they have been established.

RESUMEN

This study explored the integration and impact of artificial intelligence (AI) in diagnostic pathology, particularly dermatopathology, assessing its challenges and potential solutions for global health care enhancement. A comprehensive literature search in PubMed and Google Scholar, conducted on March 30, 2023, and using terms related to AI, pathology, and machine learning, yielded 44 relevant publications. These were analyzed under themes including the evolution of deep learning in pathology, AI's role in replacing pathologists, development challenges of diagnostic algorithms, clinical implementation hurdles, strategies for practical application in dermatopathology, and future prospects of AI in this field. The findings highlight AI's transformative potential in pathology, underscore the need for ongoing research, collaboration, and regulatory dialogue, and emphasize the importance of addressing the ethical and practical challenges in AI implementation for improved global health care outcomes.

RESUMEN

Artificial Intelligence (AI) is a very powerful new tool that is destined to markedly advance many areas of dermatology, including cosmetic dermatology, oculoplastics, cancer detection and treatment, dermatopathlogy, and identification of pathogens. Along with these are some special new risks and concerns, however, including ethical considerations, data analysis, interpretation of scientific studies, and recognizing systematic failures and fraud, particularly in generative AI. Each of these issues is reviewed collectively and in turn in this special of Clinics in Dermatology.

RESUMEN

We describe a novel assay and artificial intelligence-driven histopathologic approach identifying dermatophytes in human skin tissue sections (ie, B-DNA dermatophyte assay) and demonstrate, for the first time, the presence of dermatophytes in tissue using immunohistochemistry to detect canonical right-handed double-stranded (ds) B-DNA. Immunohistochemistry was performed using anti-ds-B-DNA monoclonal antibodies with formalin-fixed paraffin-embedded tissues to determine the presence of dermatophytes. The B-DNA assay resulted in a more accurate identification of dermatophytes, nuclear morphology, dimensions, and gene expression of dermatophytes (ie, optical density values) than periodic acid-Schiff (PAS), Grocott methenamine silver (GMS), or hematoxylin and eosin (H&E) stains. The novel assay guided by artificial intelligence allowed for efficient identification of different types of dermatophytes (eg, hyphae, microconidia, macroconidia, and arthroconidia). Using the B-DNA dermatophyte assay as a clinical tool for diagnosing dermatophytes is an alternative to PAS, GMS, and H&E as a fast and inexpensive way to accurately detect dermatophytosis and reduce the number of false negatives. Our assay resulted in superior identification, sensitivity, life cycle stages, and morphology compared to H&E, PAS, and GMS stains. This method detects a specific structural marker (ie, ds-B-DNA), which can assist with diagnosis of dermatophytes. It represents a significant advantage over methods currently in use.

RESUMEN

The development of the computer and what is now known as artificial intelligence (AI) has evolved over more than two centuries in a long series of steps. The date of the invention of the first computer is estimated at 1822, when Charles Babbage (1791-1871) developed his first design of a working computer on paper, based mainly on a Jacquard loom. He worked on his project together with Augusta Ada King, Countess Lovelace (née Byron) (Ada Lovelace) (1815-1852), whom he called the "Sorceress of Numbers." This work will present the profile and achievements of Charles Babbage, Augusta Ada King, Countess Lovelace, and Alan Mathison Turing (1912 - 1954), who is considered the father of computer science and artificial intelligence, and then provide an outline of the tumultuous events affecting AI up to the present.

RESUMEN

Artificial intelligence (AI) can be a powerful tool for data analysis, but it can also mislead investigators, due in part to a fundamental difference between classic data analysis and data analysis using AI. A more or less limited data set is analyzed in classic data analysis, and a hypothesis is generated. That hypothesis is then tested using a separate data set, and the data are examined again. The premise is either accepted or rejected with a value p, indicating that any difference observed is due merely to chance. By contrast, a new hypothesis is generated in AI as each datum is added to the data set. We explore this discrepancy and suggest means to overcome it.

RESUMEN

To retain talented scientists in academia, there is a need for structural reform to postdoctoral researcher (postdoc) mentorship. These changes include mentorship training for postdocs and their mentors, formalizing postdoc mentorship networks and postdoc cohorts within a department, and incorporating mentorship development plans (MDPs) in funding decisions for principal investigators (PIs).

RESUMEN

A symbiotic relationship between the editor and the owner of a medical journal is important for the journal to fulfill successfully the expectations of its readers and authors. Editorial freedom and transparency by owner of the journal are important qualities that enable the editor to provide valid scientific information in an unbiased manner. Unresolved impedance of editorial freedom or the persistent lack of transparency or both frequently results in untenable consequences for editor and often a substantial defamation of the journal's credibility. Unfortunately, misguided and inappropriate behavior by a medical society or the publication owner repeatedly occurs with the same devastating effect for the editor: prompt, unanticipated, and unjustified termination of the position at the journal. Alternatively, conditions imposed by a journal's owner may lead to the resignation of the editor because of untenable conditions. Because the owner does not have to account for its actions and there is no recourse for the editor, currently there seems to be no effective measures to prevent this tragic sequence of events in the future.

RESUMEN

Important components of a medical journal include its readers, authors, editor, and owner. Editor is the individual to whom the journal is branded. The editor determines the journal's published content and establishes its caliber. The success of a journal depends on the general and specific responsibilities of the editor toward its readers, authors, and owner. For a journal to maintain its stature of excellence, the expectations of the editor-including editorial independence-must be preserved; therefore, in the best interest of the journal, the owner must provide unequivocal support to the editor.

RESUMEN

Xeroderma pigmentosum (XP) is a rare autosomal recessive disease; relatively mild XP patients are sometimes designated as having pigmented xerodermoid or xerodermoid pigmentosum (XP-V), a variant of XP. It is commonly associated with many long-standing skin conditions and tumors, including malignancies, management of which is necessary to prevent the progress of the disease. The objective of the study was to report the use of a number of innovative therapeutic and prophylactic treatments, beyond surgery, such as topical 5-fluorouracil, topical imiquimod, other topical immunomodulators, or photodynamic therapy, in treating skin eruptions and their complications in XP patients. This was a prospective therapeutic interventional study in which 50 patients with XP-V were evaluated. Age of subjects ranged from 2 to 50 years with a mean age of 18 years. This study was divided into two parts. In part one, patients were treated by applying topical zinc sulfate 25% twice daily on entire face for 2 months, then once daily for several months or years. In another instance, two women were treated with heat dermabrasion with needle diathermy on the entire face under local anesthesia, followed by application of trichloroacetic acid 35% peeling in a single session. In part two, topical podophyllin 25% was used as therapy for 18 patients, all of whom had XP complications, such as keratoacanthoma, basal cell carcinomas and squamous cell cancers.1 Podophyllin was applied to the lesions until complete resolution was documented. All patients treated with topical zinc sulfate 25% responded well as determined by clearance of actinic keratoses (ActK) and small malignant lesions, minimization of pigmented freckles, prevention of new lesions, and ceased progress of eruptions. Heat dermabrasion administered in a single session resulted in the clearance of pigmented freckles, ActK, and small tumors, and cessation of new eruptions during follow-up that continued for up to 6 years.

RESUMEN

Xeroderma pigmentosum (XP) is a rare autosomal recessive disease; relatively mild XP patients are sometimes designated as having pigmented xerodermoid or xerodermoid pigmentosum (XP-V), a variant of XP. It is commonly associated with many long-standing skin conditions and tumors, including malignancies, management of which is necessary to prevent the progress of the disease. The objective of the study was to evaluate an innovative therapeutic treatment, beyond surgery, surgical excision, cryotherapy, electrocautery and curettage, or Mohs surgery, for the management of skin tumors in XP.This was a prospective therapeutic interventional study comprising 50 patients with XP-V. Age of subjects ranged from 2 to 50 years, with a mean age of 18 years. Several measures were evaluated in part one of this study, and a number of others (as reviewed in part one) were successful in prophylaxis of skin tumors in XP as well as in treating earlier stigmata of XP; however, these measures were notably less successful in treating well-developed skin tumors in XP patients, and 18 of the 50 patients evaluated in part one had well-developed tumors (total 22 lesions) refractory to treatments. Podophyllin 25% in 100-mL tincture of benzoin was applied topically to lesions until complete resolution was documented in 18 patients with XP complications, such as keratoacanthoma (KA), basal cell carcinoma, or squamous cell carcinoma. Topical podophyllin 25% in benzoin was a less destructive alternative treatment for skin cancer and KA in XP patients.

RESUMEN

Background and objectives: Pathogen avoidance is a fundamental motive that shapes many aspects of human behavior including bias against groups stereotypically linked to disease (e.g. immigrants, outgroup members). This link has only been examined in convenience samples and it is unknown how pathogen avoidance processes operate in populations experiencing prolonged and heightened pathogen threat such as healthcare professionals. We examined whether healthcare professionals demonstrate the same link between pathogen disgust and intergroup bias as has been documented among the general population. Methodology: Participants (N = 317; 210 healthcare professionals) were recruited using snowball sampling to take an online survey. Participants completed the Three Domain Disgust Scale to assess pathogen, sexual and moral disgust. Participants then rated their perceptions of a fictitious immigrant group ('Krasneeans') and the degree to which they endorsed group-binding moral values. Results: Compared to control participants, healthcare professionals reported lower levels of pathogen disgust, but not sexual or moral disgust. However, regardless of profession, higher pathogen disgust was associated with viewing Krasneeans as less likeable and more unclean. Additionally, regardless of profession, higher pathogen disgust was associated with greater endorsement of group-binding moral values, although healthcare professionals reported greater overall endorsement of group-binding moral values than did control participants. Conclusions and implications: Although healthcare professionals demonstrated lower levels of pathogen disgust, they nevertheless exhibited largely the same relationship between pathogen disgust and interpersonal biases as did control participants. One practical implication of this association is that pathogen avoidance motives may contribute to inequitable patient treatment in healthcare settings.

RESUMEN

Annular and acral/facial dyskeratotic paraneoplastic disorders are inflammatory dermatoses that occur in association with distant cancers but are not precursors, extensions, or metastases of them. There are four classical entities under this rubric: two gyrate entities, erythema annulare centrifugum and erythema gyratum repens, and two acral/facial dyskeratotic entities, acrokeratosis paraneoplastic (Bazex syndrome) and tripe palms. Each of these entities may also occur in association with another etiopathogenesis and may present either as a classical entity or as a barely recognizable disease. We discuss these entities, their associated causes, and their differential diagnoses in turn.

RESUMEN

Treating atopic dermatitis (AD) with dupilumab, a monoclonal antibody that inhibits interleukin-4 (IL-4) and interleukin-13 (IL-13), may be associated with the progression of mycosis fungoides (MF).This study aims to examine the associations between the length of dupilumab treatment, age and sex, and the onset of MF.An institutional data registry and literature search were used for a retrospective cross-sectional study. Only patients with a diagnosis of MF on dupilumab for the treatment of AD and eczematous dermatitis were included.The primary outcome was the length of dupilumab exposure, age, sex, and the onset of MF. Linear correlations (Pearson) and Cox regression analysis were used to assess the correlation and the risk.A total of 25 patients were included in this study. Five eligible patients were identified at our institution. In addition, a PubMed review identified an additional 20 patients. At the time of MF diagnosis, the median age was 58, with 42% female. Disease history was significant for adult-onset AD in most patients (n = 17, 65.4%) or recent flare of AD previously in remission (n = 3, 11.5%). All patients were diagnosed with MF, and one patient progressed to Sézary syndrome while on dupilumab, with an average duration of 13.5 months of therapy prior to diagnosis. Tumor stage at diagnosis of MF was described in 19 of the cases and ranged from an early-stage disease (IA) to advanced disease (IV). Treatment strategies included narrow-band UVB therapy, topical corticosteroids, brentuximab, pralatrexate, and acitretin. Male gender, advanced-stage disease, and older age correlated significantly with the hazard of MF onset and a shorter time to onset during dupilumab treatment.Our results suggest a correlation between the duration of dupilumab treatment and the diagnosis of MF, the higher MF stage at diagnosis, and the shorter the duration of using dupilumab to MF onset. Furthermore, elderly male patients appeared to be more at risk as both male gender and older age correlated with a hazard of MF diagnosis. The results raise the question as to whether the patients had MF misdiagnosed as AD that was unmasked by dupilumab or if MF truly is an adverse effect of treatment with dupilumab. Close monitoring of these patients and further investigation of the relationship between dupilumab and MF can shed more light on this question .
