Analysis of Different Lymphedema Assessment Tools in Women with Breast Cancer After Mastectomy.

Background: Lymphedema is a common complication after mastectomy in women with breast cancer. Several methods have been described to assess and diagnose lymphedema, one of the most studied being the perimeter and ultrasonography. However, the reliability of these methods and the correlation between them are still controversial. The aim of this study was to analyze the reliability of cytometry and ultrasound imaging in the assessment of lymphedema after mastectomy in women with breast cancer and to study the correlation between them. Methods and Results: A cross-sectional study was conducted in 29 women with mastectomy after breast cancer. Lymphedema in the arm was measured both with cytometry and ultrasonography. Reliability was calculated with intraclass correlation coefficient. The correlation between the two methods was carried out with the Pearson correlation coefficient. Both cytometry (M1: α = 0.999, ICC = 0.996; M2=: α = 0.998, ICC = 0.994) and ultrasonography (M1: α = 0.992, ICC = 0.976; M2=: α = 0.991, ICC = 0.973) are reliable methods to assess lymphedema in the arm. No significant correlation was found between them (p > 0.05). Conclusions: Cytometry and ultrasonography appear to be adequate for the measurement of edema in women with breast cancer after mastectomy. However, for an accurate measurement of lymphedema, these measurements should not be used interchangeably.

Damage in a large systemic lupus erythematosus cohort from the Spanish Society of Rheumatology Lupus Registry (RELESSER) with emphasis on the cardiovascular system: a longitudinal analysis.

OBJECTIVE: To assess organ damage, with emphasis on the cardiovascular system, over the different stages of the disease in a large SLE cohort. METHODS: Multicentre, longitudinal study of a cohort of 4219 patients with SLE enrolled in the Spanish Society of Rheumatology Lupus Registry. Organ damage was ascertained using the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI). We longitudinally analysed SDI (globally and for each domain) over time only in the 1274 patients whose dates of damage events had been recorded. RESULTS: During the first year after diagnosis of SLE, 20% of the 1274 patients presented with new damage manifestations. At years 2 and 3, new damage was recorded in 11% and 9% of patients. The annual percentage of patients with new damage after year 5 decreased to 5%. In the first year with the disease, most damage was accumulated in the musculoskeletal, neuropsychiatric and renal systems; in later stages, most damage was in the musculoskeletal, ocular and cardiovascular systems. Considering 'cerebrovascular accident' and 'claudication for 6 months' as cardiovascular items, the cardiovascular system was the second most affected system during the early stages of SLE, with 19% of the patients who presented with damage affected at first year after diagnosis. During the late stages, 20-25% of the patients presenting with new damage did so in this modified cardiovascular domain of the SDI. CONCLUSIONS: New damage occurs mainly during the first year following diagnosis of SLE. Cardiovascular damage is relevant in both the early and the late stages of the disease. Strategies to prevent cardiovascular damage should be implemented early after diagnosis of SLE.

Digital competences of university students after face-to-face and remote teaching: Video-animations digital create content.

In today's digitally advanced society, there is a need to focus on collaborative educational approaches of a socio-community nature that incorporate technology. From this perspective, the FEJYLEN and FEJYLENVAL programs were conceived and implemented for both remote (online) and face-to-face teaching. These programs are based on an E-Learning-Service methodology, enabling the training of university students in digital skills, and facilitating the transfer of their interactive educational video-animations to early childhood education centers. The study sample consisted of 221 students enrolled in Early Childhood Education and Speech Therapy Degrees. The study had two objectives: first, to compare digital competences before and after participating in the mentioned programs; and second, to evaluate the impact of the type of teaching and university training on the acquisition of digital competences. The findings indicate that students receiving face-to-face teaching demonstrated significant improvement across all digital competences' factors with a medium-high effect size. Conversely, for students receiving remote instruction, improvements were limited to only certain skill factors. Our study reveals that face-to-face teaching is associated with higher scores in digital competencies and more efficient digital content creation. In conclusion, this research highlights the advantages of face-to-face teaching in comparison to remote instruction. This has facilitated a closer connection between the university and the realities faced by educational centers, fostering the exchange of knowledge between learning communities.

Appearance Dissatisfaction and Body Dysmorphic Disorder in the Dermatology Patient.

Dermatologists routinely see patients with inflammatory skin conditions and aesthetic concerns that involve substantial psychological comorbidity. However, most dermatologists do not receive formal training in this area, and many are unsure how to best help treat certain patients holistically. Body dysmorphic disorder (BDD) is a common and distressing psychiatric condition that disproportionately impacts dermatology patients, including patients living with chronic inflammatory skin conditions such as acne and atopic dermatitis. BDD is characterized by preoccupation with nonexistent or minimally noticeable flaws in physical appearance that cause clinically significant distress or impairment in functioning. Adolescent populations may be particularly vulnerable to clinically significant body image dissatisfaction, including BDD, due to the high prevalence of acne and the pervasive role of social media platforms. The rise of social media may exacerbate body image issues through repetitive exposure to idealized and often unrealistic beauty standards. Though screening questionnaires can assist dermatologists in recognizing BDD, dermatologists must collaborate with mental health providers to provide comprehensive care to vulnerable patients, including adolescents.J Drugs Dermatol. 2024;23(7):545-550.  doi:10.36849/JDD.8156.

Attentiveness and mental health in adolescents with moderate-to-severe atopic dermatitis without ADHD.

Patients with moderate-to-severe atopic dermatitis (AD) experience intense chronic itch and impaired sleep. Reports from parents and teachers suggest that AD patients may also have attention problems. However, attention has not yet been directly assessed in AD patients. We utilized an objective, computer-based continuous performance test (CPT) validated for use in attention-deficit/hyperactivity disorder (ADHD) diagnosis to formally evaluate attention in adolescent AD subjects. This was a single-visit, cross-sectional, non-interventional study of moderate-to-severe (Investigator's Global Assessment [IGA] ≥ 3) AD subjects aged 12-17 years without clinician-diagnosed ADHD. Attention was evaluated using two performance-based measures: Conners, CPT-3 and the Stroop Color and Word Test. The primary parameter was CPT-3 detectability (d') measure. Lesional severity measures included Eczema Area and Severity Index (EASI) and body surface area (BSA) involvement. Subjects completed self-report rating scales assessing sensory responsiveness patterns (Adult/Adolescent Sensory Profile [AASP]), itch (Peak Pruritus Numerical Rating Scale [PP-NRS]), skin pain, quality of life, sleep, anxiety, and depressive symptoms. A total of 44 subjects were included in the study (61.4% female; mean age 15.0 [SD 1.78] years; mean EASI 20.4 [SD 7.8]; mean PP-NRS 7.0 [SD 1.8]). Results indicated substantial disease impact on sleep, quality of life, and comorbid anxiety and depressive symptoms. The mean (SD) Conners, CPT-3 d' T-score was 48.7 (SD 10.7), similar to the expected mean from a randomly selected age/gender-matched sample of the general population (50 [SD 10], by definition). Overall, 13.6% of subjects exhibited a d' T-score ≥ 60 (clinically significant poor performance), which was not greater than the expected general population value (15.9%). Subject-level data review by two psychologists determined that only 2 subjects demonstrated an overall response pattern that clearly indicated attention deficit. Many subjects had atypical sensory responsiveness profiles: sensory hypersensitivity (38.6%), sensory avoidance (50%), and low registration (hypo-sensitivity, 36.4%). Adolescents with moderate-to-severe AD without existing ADHD diagnosis did not demonstrate greater attention problems on performance-based measures than would be expected in age/gender-matched peers.Trial registration NCT05203380.

Atopic dermatitis (often shortened to AD) is a long-term skin disease that causes intense itching. It affects patients' lives in many ways, including interrupting their sleep. Parents and teachers of young people with AD have sometimes suggested that AD may also cause attention problems. But this has never been tested properly.We measured the attention of 44 adolescents aged between 12 and 17 years who all had moderate-to-severe AD. We used computerized tests of attention that were developed for young people with ADHD (attention deficit hyperactivity disorder). Also, we made sure that none of the 44 patients had also been diagnosed with ADHD. The severity and extent of the patients' AD was measured by doctors. We also used some measures that allowed the patients to report how AD affected their lives, including things like itch, skin pain, quality of life, sleep, anxiety, and depression.The adolescent patients reported that AD had a negative effect on various areas of their lives, including sleep and quality of life, and that it resulted in anxiety and symptoms of depression. However, the results of the attention tests in adolescents with AD were similar to what would usually be expected in adolescents without AD. Only 2 of the 44 patients with AD were found to have clear evidence of attention problems.The study concluded that adolescents with moderate-to-severe AD did not have any greater attention problems than would usually be expected in adolescents without AD.

Combination of toxicological and epidemiological approaches for estimating the health impact of atmospheric pollutants. A proof of concept for NO2.

BACKGROUND: Regular monitoring of the air pollutant nitrogen dioxide (NO2), an indicator for traffic-related emissions, is a priority in urban environments. The health impacts associated with NO2 exposure are the result of a combination of factors, including concentration, duration of exposure, and interactions with other pollutants. WHO has established air quality guidelines based on epidemiological studies. OBJECTIVE: This study develops a new concept "Health Impact Pathways (HIPs)" using adversity as a probabilistic indicator of health effects. For this purpose, it integrates available toxicological and epidemiological information, using Adverse Outcome Pathways (AOPs), in order to understand chemical-biological interactions and their consequences on health. METHODS: Literature review and meta-analysis of toxicological data supported by expert judgment were performed to establish: a) adversity pathways, b) quantitative criteria for scoring the observed toxicological effects (adversity indicators), c) NO2 exposure - adversity relationship for both long-term (1-36 months) and shortterm (1-7 days). The NO2 daily concentrations from January 2001 to December 2022, were obtained from Madrid city Air Quality network monitoring database. Adversity levels were compared with relative risk levels for all-cause and respiratory mortality estimated using linear equations from WHO 2021 guidelines. RESULTS: Non-linear relations were obtained for all long- and short-term NO2 related adversity indicators; for long-term effects, the best fitting was obtained with a modified Haber's law model with an exponential coefficient for the exposure time of 0.25. Estimations are presented for a set of case studies for Madrid city, covering temporal and spatial variability. A clear improvement trend along the two decades was observed, as well as high inter- and intra-station variability; the adversity indicators provided integrated information on the temporal and spatial evolution of population level risk. DISCUSSION: The proposed HIP conceptual approach offers promising advances for integrating experimental and epidemiological data. The next step is linking the concentration-adversity relationship with population health impacts through probability estimations, the preliminary estimations confirm the need for assessing independently different population groups.

Prospective study on stereotactic body radiotherapy for small pancreatic neuroendocrine tumors: tolerance and effectiveness analysis.

INTRODUCTION: Surgery is the standard treatment for pancreatic neuroendocrine tumors (pNETs), obtaining favorable results but associating high morbidity and mortality rates. This study assesses stereotactic body radiation therapy (SBRT) as a radical approach for small (< 2 cm) nonfunctioning pNETs. MATERIALS AND METHODS: From January 2017 to June 2023, 20 patients with small pNETs underwent SBRT in an IRB-approved study. Endpoints included local control, tolerance, progression-free survival, and overall survival (OS). Diagnostic assessments comprised endoscopy, CT scans, OctreScan or PET-Dotatoc, abdominal MRI, and histological confirmatory samples. RESULTS: In a 30-month follow-up of 20 patients (median age 55.5 years), SBRT was well-tolerated with no grade > 2 toxicity. 40% showed morphological response, 55% remained stable. Metabolically, 50% achieved significant improvement. With a median OS of 41.5 months, all patients were alive without local or distant progression or need for surgical resection. CONCLUSION: SBRT is a feasible and well-tolerated approach for small neuroendocrine pancreatic tumors, demonstrating effective local control. Further investigations are vital for validation and extension of these findings.

Reference intervals for reticulocyte count and derived reticulocyte parameters in a cohort of healthy adults.

INTRODUCTION: Reticulocyte count and novel derived parameters provide insight into the effectiveness of erythropoiesis and may be useful tools in the classification and diagnosis of anemias. However, there is no standardisation, so we consider it necessary that each laboratory evaluates the parameters according to its own methodology and instrumentation and establishes its own reference ranges. Our aim was to establish the reference intervals (RIs) of reticulocyte profile provided by the Beckman Coulter DxH 900 haematological autoanalyzer in our reference population. METHODS: One hundred and seventy-five healthy adults (18 to 62 years) were included. Subjects were collected from the blood donation centre of the Hospital Clínico San Carlos (Madrid, Spain) upon informed consent. Whole blood was collected and assayed for 14 haematological parameters on the Beckman Coulter DxH 900 analyzer in the haematology laboratory of the Clinical Analysis Department. RIs were established as per Clinical and Laboratory Standards Institute EP28-A3c guidelines using three different statistical approaches. RESULTS: RIs estimated using the non-parametric method and the Harrell-Davis bootstrap method were very similar. RIs estimated by the robust method were narrower. Gender partitioning was required for two haematological parameters (low haemoglobin density (LHD) and microcytic anaemia factor (MAF)). The rest of the parameters did not need to be partitioned according to Lahti's method. CONCLUSION: RIs have been established for 14 hematologic parameters of the reticulocyte profile for the Beckman Coulter DxH 900 haematology analyzer using a healthy cohort of adult subjects.

Practical considerations relevant to treatment with the gene therapy beremagene geperpavec-svdt for dystrophic epidermolysis bullosa.

BACKGROUND/PURPOSE: Dystrophic epidermolysis bullosa (DEB), a rare genetic skin disease caused by loss-of-function mutations in COL7A1, the gene encoding type VII collagen (COL7), is characterized by skin blistering, scarring, and extracutaneous manifestations that markedly reduce patient quality-of-life. Beremagene geperpavec-svdt ('B-VEC') is a gene therapy employing a non-integrating, replication-defective herpes simplex virus type 1 (HSV-1)-based vector encoding two copies of full-length human COL7A1 to restore COL7 protein after topical administration to DEB wounds. B-VEC was approved in the United States in 2023 as the first topical gene therapy and the first approved treatment for DEB. However, few providers have experience with use of this gene therapy. METHODS: Data was obtained through literature review and the experience of providers who participated in the B-VEC clinical study or initiated treatment after B-VEC approval. RESULTS: This review discusses the burden of disease, describes the clinical trial outcomes of B-VEC, and provides physician and patient/caregiver recommendations as a practical guide for the real-world use of B-VEC, which can be administered in-office or at the patient's home. CONCLUSIONS: By continuing to optimize the practical aspects of B-VEC administration, the focus will continue to shift to patient-centric considerations and improved patient outcomes.

Janus kinase inhibitors and tumour necrosis factor inhibitors show a favourable safety profile and similar persistence in rheumatoid arthritis, psoriatic arthritis and spondyloarthritis: real-world data from the BIOBADASER registry.

OBJECTIVES: To compare the safety of Janus kinase inhibitors (JAKi) with that of tumour necrosis factor inhibitors (TNFi) and determine drug persistence among patients with rheumatoid arthritis (RA) and spondyloarthritis (SpA). METHODS: We analysed data from patients included in BIOBADASER 3.0 and treated with JAKi or TNFi from 2015 to 2023 and estimated the incidence rate ratio (IRR) of adverse events and persistence. RESULTS: A total of 6826 patients were included. Of these, 52% had RA, 25% psoriatic arthritis and 23% axial SpA. Treatment was with TNFi in 86%. The mean duration of treatment was 2.2±2.0 years with TNFi versus 1.8±1.5 with JAKi. JAKis were prescribed in older patients with longer term disease, greater comorbidity and later treatment lines and more frequently as monotherapy. The IRR of all infections and gastrointestinal events was higher among patients with RA treated with JAKi. Drug persistence at 1, 2 and 3 years was 69%, 55% and 45% for TNFi and 68%, 54% and 45% for JAKi. Multivariate regression models showed a lower probability of discontinuation for JAKi (HR=0.85; 95% CI 0.78-0.92) and concomitant conventional synthetic disease-modifying antirheumatic drugs (HR=0.90; 95% CI 0.84-0.96). The risk of discontinuation increased with glucocorticoids, comorbidities, greater disease activity and later treatment lines. CONCLUSIONS: Infections, herpes zoster and gastrointestinal adverse events in patients with RA tended to be more frequent with JAKi. However, prognosis was poor in patients receiving JAKi. Persistence was similar for TNFi and JAKi, although factors associated with discontinuation differed by diagnostic group.

Effects of nanomolar methylmercury on developing human neural stem cells and zebrafish Embryo.

Exposure to mercury and its organic form methylmercury (MeHg), is of great concern for the developing nervous system. Despite available literature on MeHg neurotoxicity, there is still uncertainty about its mechanisms of action and the doses that trigger developmental effects. Our study combines two alternative methodologies, the human neural stem cells (NSC) and the zebrafish (ZF) embryo, to address the neurotoxic effects of early exposure to nanomolar concentrations of MeHg. Our results show linear or nonmonotonic (hormetic) responses depending on studied parameters. In ZF, we observed a hormetic response in locomotion and larval rotation, but a concentration-dependent response for sensory organ size and habituation. We also observed a possible delayed response as MeHg had greater effects on larval activity at 5 days than at 24 h. In NSC cells, some parameters show a clear dose dependence, such as increased apoptosis and differentiation to glial cells or decreased neuronal precursors; while others show a hormetic response: neuronal differentiation or cell proliferation. This study shows that the ZF model was more susceptible than NSC to MeHg neurotoxicity. The combination of different models has improved the understanding of the underlying mechanisms of toxicity and possible compensatory mechanisms at the cellular and organismal level.

SLESIS-R: an improved score for prediction of serious infection in patients with systemic lupus erythematosus based on the RELESSER prospective cohort.

OBJECTIVE: To develop an improved score for prediction of severe infection in patients with systemic lupus erythematosus (SLE), namely, the SLE Severe Infection Score-Revised (SLESIS-R) and to validate it in a large multicentre lupus cohort. METHODS: We used data from the prospective phase of RELESSER (RELESSER-PROS), the SLE register of the Spanish Society of Rheumatology. A multivariable logistic model was constructed taking into account the variables already forming the SLESIS score, plus all other potential predictors identified in a literature review. Performance was analysed using the C-statistic and the area under the receiver operating characteristic curve (AUROC). Internal validation was carried out using a 100-sample bootstrapping procedure. ORs were transformed into score items, and the AUROC was used to determine performance. RESULTS: A total of 1459 patients who had completed 1 year of follow-up were included in the development cohort (mean age, 49±13 years; 90% women). Twenty-five (1.7%) had experienced ≥1 severe infection. According to the adjusted multivariate model, severe infection could be predicted from four variables: age (years) ≥60, previous SLE-related hospitalisation, previous serious infection and glucocorticoid dose. A score was built from the best model, taking values from 0 to 17. The AUROC was 0.861 (0.777-0.946). The cut-off chosen was ≥6, which exhibited an accuracy of 85.9% and a positive likelihood ratio of 5.48. CONCLUSIONS: SLESIS-R is an accurate and feasible instrument for predicting infections in patients with SLE. SLESIS-R could help to make informed decisions on the use of immunosuppressants and the implementation of preventive measures.

Transcriptomic characterization of the response to a microalgae extract in Arabidopsis thaliana and Solanum lycopersicum.

BACKGROUND: The steady world population growth and the current climate emergency crisis demand the development of sustainable methods to increase crop performance and resilience to the abiotic and biotic stresses produced by global warming. Microalgal extracts are being established as sustainable sources to produce compounds that improve agricultural yield, concurrently contributing during their production process to atmospheric CO2 abatement through the photosynthetic activity of microalgae. RESULTS: In the present study, we characterize the transcriptomic response in the model plant Arabidopsis thaliana and the plant of horticultural interest Solanum lycopersicum to the foliar application of a microalgae-based commercial preparation LRM™ (AlgaEnergy, Madrid, Spain). The foliar spray of LRM™ has a substantial effect over both transcriptomes potentially mediated by various compounds within LRM™, including its phytohormone content, activating systemic acquired resistance, possibly mediated by salicylic acid biosynthetic processes, and drought/heat acclimatization, induced by stomatal control and wax accumulation during cuticle development. Specifically, the agronomic improvements observed in treated S. lycopersicum (tomato) plants include an increase in the number of fruits, an acceleration in flowering time and the provision of higher drought resistance. The effect of LRM™ foliar spray in juvenile and adult plants was similar, producing a fast response detectable 2 h from its application that was also maintained 24 h later. CONCLUSION: The present study improves our knowledge on the transcriptomic effect of a novel microalgal extract on crops and provides the first step towards a full understanding of the yield and resistance improvement of crops. © 2024 The Authors.

Internalization and toxicity of polystyrene nanoplastics on inmortalized human neural stem cells.

Global plastic production has increased exponentially in recent decades, and a significant part of it persists in the environment, where it degrades into microplastics and nanoplastics (MPs and NPs). These can enter in humans by ingestion, inhalation, and dermal routes, and there is scientific evidence that they are able to reach the systemic circulation and penetrate and accumulate in various tissues and organs. Neurodevelopmental toxicity of NPs is one of the most worrying effects, as they can cross the blood-brain barrier. In the following study, we analyzed, by transmission electron microscopy, the in vitro uptake of 30-nm polystyrene nanoplastics (PS-NPs) into human neural stem cells (NSCs), their accumulation and subcellular localization within the cell. Furthermore, we studied the effects of different concentrations of PS-NPs on cell death, proliferation, and cell differentiation using immunocytochemistry and quantitative real time PCR for specific markers. This study demonstrated that PS-NPs were able to enter the cell, probably by endocytosis, accumulate, and aggregated in human NSCs, without being detected in the nucleus, causing cell death by apoptosis and decreased cell proliferation. This study provides new insights into the interaction and effects of PS-NPs in human NSC and supports the scientific evidence for the involvement of nanoplastic in neurodevelopmental disorders.

Clustering COVID-19 ARDS patients through the first days of ICU admission. An analysis of the CIBERESUCICOVID Cohort.

BACKGROUND: Acute respiratory distress syndrome (ARDS) can be classified into sub-phenotypes according to different inflammatory/clinical status. Prognostic enrichment was achieved by grouping patients into hypoinflammatory or hyperinflammatory sub-phenotypes, even though the time of analysis may change the classification according to treatment response or disease evolution. We aimed to evaluate when patients can be clustered in more than 1 group, and how they may change the clustering of patients using data of baseline or day 3, and the prognosis of patients according to their evolution by changing or not the cluster. METHODS: Multicenter, observational prospective, and retrospective study of patients admitted due to ARDS related to COVID-19 infection in Spain. Patients were grouped according to a clustering mixed-type data algorithm (k-prototypes) using continuous and categorical readily available variables at baseline and day 3. RESULTS: Of 6205 patients, 3743 (60%) were included in the study. According to silhouette analysis, patients were grouped in two clusters. At baseline, 1402 (37%) patients were included in cluster 1 and 2341(63%) in cluster 2. On day 3, 1557(42%) patients were included in cluster 1 and 2086 (57%) in cluster 2. The patients included in cluster 2 were older and more frequently hypertensive and had a higher prevalence of shock, organ dysfunction, inflammatory biomarkers, and worst respiratory indexes at both time points. The 90-day mortality was higher in cluster 2 at both clustering processes (43.8% [n = 1025] versus 27.3% [n = 383] at baseline, and 49% [n = 1023] versus 20.6% [n = 321] on day 3). Four hundred and fifty-eight (33%) patients clustered in the first group were clustered in the second group on day 3. In contrast, 638 (27%) patients clustered in the second group were clustered in the first group on day 3. CONCLUSIONS: During the first days, patients can be clustered into two groups and the process of clustering patients may change as they continue to evolve. This means that despite a vast majority of patients remaining in the same cluster, a minority reaching 33% of patients analyzed may be re-categorized into different clusters based on their progress. Such changes can significantly impact their prognosis.

Attenuation of Atopic Dermatitis in Newborns, Infants, and Children With Prescription Treatment and Ceramide-Containing Skin Care: A Systematic Literature Review and Consensus.

BACKGROUND: Atopic dermatitis (AD) typically starts in infancy and early childhood. The chronic skin disorder is associated with recurrent flares, pruritus, and genetic predisposition. Daily use of moisturizers that contain lipids, such as ceramides, reduces the rate of AD flares and the need for topical steroid treatment. We aimed to provide insights on AD attenuation to tailor AD prescription therapy, skin care, and maintenance treatment to improve pediatric patients with AD and families. METHODS: A panel of 6 pediatric dermatologists and dermatologists who treat neonates, infants, and children developed a consensus paper on AD attenuation for pediatric patients. The modified Delphi process comprised a face-to-face panel meeting and online follow-up to discuss the systematic literature search results and draw from clinical experience and opinion of the panel to adopt and agree on 5 statements.  Results: Understanding the functional properties of newborn and infant skin, discussing skincare product use with parents, and recommending tailored prescription and skincare routines can improve newborn, infant, and children’s skin health. Studies on the prophylactic application of moisturizers initiated in early infancy suggest moisturizers may delay rather than prevent AD, especially in high-risk populations and when used continuously. Increasingly there is evidence that moisturizer application reduces the severity of AD and extends the time to flares, which may help attenuate the atopic march. The protective effect of skin care for AD has been observed in studies where its daily use is ongoing; these beneficial effects may be lost in less than 1year after cessation. It is therefore important to emphasize that skin care should be routinely used when counseling patients and caregivers.  Conclusion: Healthcare providers can improve patient outcomes in atopic-prone infants and children by providing instructions regarding the daily benefits of applying skin care with gentle cleansers and moisturizers. Using gentle cleansers and moisturizers containing barrier lipids from birth onward may delay AD occurrence and mitigate severity in predisposed infants.J Drugs Dermatol. 2024;23(3): doi:10.36849/JDD.7894.

Effects of Muscle Strength Training in Prostate Cancer: A Systematic Review.

INTRODUCTION: Prostate cancer is one of the most frequently diagnosed cancers in males. Treatment options cause a series of side effects that can lead to a deterioration in the physical and quality of life of patients, such as musculoskeletal changes, atrophy or muscle weakness, due to the testosterone suppression. Scientific evidence has shown that exercise mitigates the side effects induced by cancer treatment. This study aimed to analyse the effects of muscular strength work on the organism of patients with prostate cancer in the treatment phase. MATERIAL AND METHODS: PubMed, Scopus, SPORTDiscus, CINAHL, Medline, Web of Science and PEDro databases were searched in January 2022. The Medical Subject Headings "resistance training", "prostatic neoplasms", "strength training" and "prostate cancer" were used. RESULTS: A total of 13 articles were analysed. In all of them, statistically significant changes were found in strength, physical performance, muscle mass and cardiovascular and respiratory health after the implementation of a strength exercise program. Other variables did not achieve the expected changes. CONCLUSIONS: A strength exercise program improves strength, physical performance, muscle mass and cardiovascular health in patients with prostate cancer. However, whether it improves other parameters, such as body fat, power, bone density and quality of life, is unclear.

WT1-related disorders: more than Denys-Drash syndrome.

Historically, specific mutations in WT1 gene have been associated with distinct syndromes based on phenotypic characteristics, including Denys-Drash syndrome (DDS), Frasier syndrome (FS), Meacham syndrome, and WAGR syndrome. DDS is classically defined by the triad of steroid-resistant nephrotic syndrome (SRNS) onset in the first year of life, disorders of sex development (DSD), and a predisposition to Wilms tumor (WT). Currently, a paradigm shift acknowledges a diverse spectrum of presentations beyond traditional syndromic definitions. Consequently, the concept of WT1-related disorders becomes more precise. A genotype-phenotype correlation has been established, emphasizing that the location and type of WT1 mutations significantly influence the clinical presentation, the condition severity, and the chronology of patient manifestations. Individuals presenting with persistent proteinuria, with or without nephrotic syndrome, and varying degrees of kidney dysfunction accompanied by genital malformations should prompt suspicion of WT1 mutations. Recent genetic advances enable a more accurate estimation of malignancy risk in these patients, facilitating a conservative nephron-sparing surgery (NSS) approach in select cases, with a focus on preserving residual kidney function and delaying nephrectomies. Other key management strategies include kidney transplantation and addressing DSD and gonadoblastoma. In summary, recent genetic insights underscore the imperative to implement individualized, integrated, and multidisciplinary management strategies for WT1-related disorders. This approach is pivotal in optimizing patient outcomes and addressing the complexities associated with these diverse clinical manifestations.

Monocyte distribution width (MDW): study of reference values in blood donors.

OBJECTIVES: Monocyte distribution width (MDW) is a new biomarker used as an early indicator of sepsis (ESId). It is often aids in the identification of patients who may develop sepsis. This study aims to establish the MDW reference interval (RI) within the healthy population of blood donors using EDTA-K2 as anticoagulant. Many hospitals use this biomarker as a means of identifying patients who present to the hospital with sepsis. METHODS: A total of 274 samples obtained from healthy donors were analyzed. MDW measurements were taken within 2 h post-extraction. The RI was estimated using various statistical methodologies, including the recommended CLSI EP28-A3c guideline, non-parametric and robust methods, along with the Harrell-Davis bootstrap method applied to the entire sample. RESULTS: The RI estimated through non-parametric method was 14.77 CI90 % (14.36-14.97)-21.13 CI90 % (20.89-21.68); RI using the robust method was 15.64-19.05 and RI using the Harrell-Davis bootstrap method was 14.73 CI90 % (14.53-14.92)-21.14 CI90 % (20.88-21.40). CONCLUSIONS: Based on clinical applicability, we recommend utilizing the RI derived from the non-parametric method, aligning with the CLSI recommendations. Furthermore, we consider that our results can be taken as a reference in other laboratories that serve a population similar to our study cohort.

Molecular effects of polystyrene nanoplastics on human neural stem cells.

Nanoplastics (NPs) have been found in many ecological environments (aquatic, terrestrial, air). Currently, there is great concern about the exposition and impact on animal health, including humans, because of the effects of ingestion and accumulation of these nanomaterials (NMs) in aquatic organisms and their incorporation into the food chain. NPs´ mechanisms of action on humans are currently unknown. In this study, we evaluated the altered molecular mechanisms on human neural stem cell line (hNS1) after 4 days of exposure to 30 nm polystyrene (PS) NPs (0.5, 2.5 and 10 µg/mL). Our results showed that NPs can induce oxidative stress, cellular stress, DNA damage, alterations in inflammatory response, and apoptosis, which could lead to tissue damage and neurodevelopmental diseases.
