Pigmented acuminated condylomas seborrhoeic keratosis-like: a new entity?

BACKGROUND: Condyloma acuminatum is caused by human papillomavirus (HPV), which typically presents as excrescent, pedunculated, papillomatous lesions which may be of a pale colour. On rare occasions, we have observed pigmented genital lesions that are similar to seborrhoeic keratoses, but with histological findings of condyloma acuminatum and positive genotyping for HPV. We have termed these 'seborrhoeic keratosis-like' type condylomas. METHODS: This is an observational retrospective study. The following clinical data were collected: age, sex, time of evolution, location, isolated or multiple lesions, monomorphous or polymorphous/mixed lesions. HPV genotyping was performed in all cases, and excision for histological study in eight cases. RESULTS: A total of 31 patients were diagnosed with this type of pigmented condylomata acuminata. Of these, 16 had isolated lesions (less than five lesions) and 15 had multiple lesions. 67% of the lesions exhibited slow growth, with an evolution period of greater than 1 year. The most frequent location was the base of the penis and pubis. HPV genotyping of the lesions was positive in all cases, with the HPV-6 genotype predominating (28 cases, 90.3%). The lesions exhibited dermoscopic differences from other pigmented lesions and histological findings attributable to HPV infection (pseudoparakeratosis, koilocytosis, etc) and others similar to those observed in seborrhoeic keratoses. CONCLUSIONS: A total of 31 patients were diagnosed with pigmented verrucous lesions, excrescents, isolated or multiple, in the genital region. These lesions exhibited clinical characteristics similar to seborrhoeic keratoses, with positive genotyping for HPV. In the majority of cases, the genotype was HPV-6. These lesions have been named 'pigmented condylomata acuminata seborrhoeic keratosis-like'. Only 10 cases of these lesions have been described in the literature.

Five years of advances in electrochemical analysis of protein biomarkers in lung cancer: a systematic review.

Lung cancer is the leading cause of cancer death in both men and women. It represents a public health problem that must be addressed through the early detection of specific biomarkers and effective treatment. To address this critical issue, it is imperative to implement effective methodologies for specific biomarker detection of lung cancer in real clinical samples. Electrochemical methods, including microfluidic devices and biosensors, can obtain robust results that reduce time, cost, and assay complexity. This comprehensive review will explore specific studies, methodologies, and detection limits and contribute to the depth of the discussion, making it a valuable resource for researchers and clinicians interested in lung cancer diagnosis.

Associations between muscular strength and mental health in cognitively normal older adults: a cross-sectional study from the AGUEDA trial.

Objective: To examine the associations between muscular strength and mental health. Design: We used baseline data of 91 cognitively healthy older adults (71.69 ± 3.91 years old, 57 % women) participating in the AGUEDA randomized controlled trial. Methods: Muscular strength was assessed using both objective (i.e., handgrip strength, biceps curl, squats, and isokinetic test) and perceived (i.e., International Fitness Scale) indicators. Psychological ill-being indicators: anxiety, depression, stress, and loneliness; and psychological well-being indicators: satisfaction with life, self-esteem, and emotional well-being) were assessed using a set of valid and reliable self-reported questionnaires. Linear regression analyses were performed adjusting for sex, age, years of education, body mass index , alcohol, diet, and smoking (model 1), and additionally by cardiorespiratory fitness (model 2). Results: Elbow extension was positively associated with stress in model 1 (ß = 0.252, 95 % Confidence Interval [95 % CI] = 0.007 to 0.497, p = 0.044), and even after further adjustment for cardiorespiratory fitness (ß = 0.282, 95 % CI = 0.032 to 0.532, p = 0.028). Perceived strength was negatively associated with depressive symptoms in model 1 (ß = -0.271, 95 % CI = -0.491 to -0.049, p = 0.017) and model 2 reported associations tending towards significant (ß = -0.220, 95 % CI = -0.445 to 0.005, p = 0.055). Handgrip strength was positively associated with self-esteem in model 1 (ß = 0.558, 95 % CI = 0.168 to 0.949, p = 0.006) and model 2 (ß = 0.546, 95 % CI = 0.135 to 0.956, p = 0.010). No further associations were found among other muscular strength and mental health variables. Conclusion: Handgrip had a moderate association with self-esteem and there was a small association between perceived strength with depressive symptoms and elbow extension with stress. No other associations were observed between muscular strength and mental health outcomes in cognitively normal older adults.

Every Move Counts to Improve Bone Health at Clinical Sites in Young Pediatric Cancer Survivors: The iBoneFIT Project.

PURPOSE: We aimed to examine the associations of 24-h movement behaviors (moderate to vigorous physical activity [MVPA], light physical activity [LPA], sedentary behavior [SB], and sleep) with age-, sex-, and race-specific areal bone mineral density (aBMD) z -score parameters at clinical sites in young pediatric cancer survivors. METHODS: This cross-sectional multicenter study was carried out within the iBoneFIT framework in which 116 young pediatric cancer survivors (12.1 ± 3.3 yr old; 42% female) were recruited. We obtained anthropometric and body composition data (i.e., body mass, stature, body mass index, and region-specific lean mass), time spent in movement behaviors over at least seven consecutive 24-h periods (wGT3x-BT accelerometer, ActiGraph), and aBMD z -score parameters (age-, sex-, and race-specific total at the body, total hip, femoral neck and lumbar spine). Survivors were classified according to somatic maturity (pre or peri/postpubertal depending on the estimated years from peak height velocity). The adjusted models' coefficients were used to predict the effect of reallocating time proportionally across behaviors on the outcomes. RESULTS: In prepubertal young pediatric cancer survivors, reallocating time to MVPA from LPA, SB, and sleep was significantly associated with higher aBMD at total body ( B = 1.765, P = 0.005), total hip ( B = 1.709, P = 0.003), and lumbar spine ( B = 2.093, P = 0.001). In peri/postpubertal survivors, reallocating time to LPA from MVPA, SB, and sleep was significantly associated with higher aBMD at all sites ( B = 2.090 to 2.609, P = 0.003 to 0.038). Reallocating time to SB from MVPA or LPA was significantly associated with lower aBMD at most sites in prepubertal and peri/postpubertal survivors, respectively. Finally, reallocating time to sleep from MVPA, LPA, and SB was significantly associated with lower aBMD at total body ( B = -2.572, P = 0.036) and total hip ( B = -3.371, P = 0.015). CONCLUSIONS: These findings suggest that every move counts and underline the benefits of increasing MVPA or LPA, when low MVPA levels are present, for bone regeneration after pediatric cancer treatment completion.

Trauma e literalidade: a razão psicodinâmica no espírito da traumatização neurocientífica / Trauma and literality: psychodynamic reason in the spirit of neuroscientific traumatization

Resumo Desde o seu nascimento na medicina cirúrgica do século XVII, a pesquisa do trauma admitiu interpretações múltiplas e associadas ora às lesões visíveis de órgãos e tecidos, ora à influência de agentes psíquicos patogênicos sobre a memória, a consciência e a personalidade. Com o aprofundamento do papel dos sistemas classificatórios desde DSM-III, o fenômeno do trauma será incorporado ao prisma psiquiátrico através do Transtorno de Estresse Pós-Traumático e destinado, finalmente, à circunscrição da pesquisa neurocientífica. A partir de revisão narrativa, este artigo abordará uma das premissas epistemológicas fundamentais para essa transição, que informa como o trauma psicológico ganhou autonomia sobre as descrições anatômicas para ser, cerca de um século depois, por ela reanexado enquanto fenômeno essencialmente corporal e aderido à gramática das neurociências.

Abstract Since its origin in the surgical medicine of the 17th century, trauma research has had multiple interpretations and has been associated either with visible injuries to organs and tissues, or with the influence of pathogenic psychic agents on memory, consciousness and personality. With the intensification of the role of classification systems since DSM-III, the phenomenon of trauma came to be incorporated into the psychiatric realm through Post-Traumatic Stress Disorder and destined finally to the constraints of neuroscientific research. Based on a narrative review, this article will address one of the fundamental epistemological premises for this transition, which informs how psychological trauma gained autonomy over anatomical descriptions to be reclassified, around a century later, as an essentially bodily phenomenon and incorporated into the jargon of neurosciences.

Introduction: Informal caregivers of pediatric patients with epilepsy confront a myriad of challenges that may adversely affect their health, with one prominent challenge being the magnitude of the burden they experience. Objective: This study aims to ascertain the level of burden, sociodemographic characteristics, and caregiving attributes among informal caregivers of pediatric patients diagnosed with epilepsy. Methodology: A descriptive, quantitative, and cross-sectional study was conducted, involving the participation of 89 caregivers of pediatric patients diagnosed with epilepsy in 2021. A survey was administered to gather sociodemographic and caregiving-related information, along with the application of the Zarit Scale to quantify the caregiver burden. Descriptive statistics were employed to present the findings. Results: Among the caregivers of pediatric patients with epilepsy, 97% were female. The majority of caregivers had a low income, dedicated more than 8 hours to caregiving responsibilities, and lacked consistent support in their caregiving role. Six out of ten caregivers reported experiencing some degree of burden. Conclusions: Caregivers of pediatric patients diagnosed with epilepsy encounter varying degrees of burden, ranging from mild to intense. The prevalent caregiver profile is characterized by females, often single, with incomes below the Chilean minimum wage, high rates of absenteeism, and insufficient support in their caregiving responsibilities. Gender disparities in caregiving are evident, emphasizing the urgent need to reform current public policies on caregiving, with a particular focus on bolstering support for informal caregivers.

Baseline extracellular vesicle miRNA-30c and autophagic CTCs predict chemoradiotherapy resistance and outcomes in patients with lung cancer.

Concurrent chemoradiotherapy (cCRT) is the mainstay of treatment for patients diagnosed with locally advanced non-small cell lung cancer (NSCLC). One significant challenge in the effectiveness of this therapy is the potential development of resistance mechanisms, where autophagy up-regulation has been proposed as a key contributing factor. However, there is a lack of reliable biomarkers to predict outcomes on these patients. Interestingly, for addressing this gap, extracellular vesicles (EVs) and circulating tumor cells (CTCs) have emerged as potential sources of such biomarkers. In this study, we investigated EV-associated miRNAs and presence of autophagic CTCs in prospectively collected serial samples from 38 patients with stage III NSCLC undergoing cCRT. Our findings revealed that non-responders exhibited low levels of baseline EV miR-375, miR-200c, and miR-30c. In particular, EV miR-30c showed high predictive value with an area under the curve of 87.2%. Low EV miR-30c and the presence of autophagic-activated CTCs emerged as independent predictive biomarkers for shorter relapse-free survival and overall survival. Furthermore, in experimental models simulating the effects of chemo- and radiotherapy, the administration of miR-30c, either through direct transfection or encapsulation into human EVs, led to the inhibition of autophagy in these cells. This is the first report demonstrating that EV miR-30c inhibits tumor autophagy and its quantification, together with autophagic-activated CTCs, could be used as biomarkers for the stratification and monitoring of patients with NSCLC undergoing cCRT, and they may hold promising potential for guiding subsequent consolidation treatment with immunotherapy or other novel therapies based on autophagy inhibitors.

Inflammatory response to bacterial lipopolysaccharide drives iron accumulation in human adipocytes.

The association among increased inflammation, disrupted iron homeostasis, and adipose tissue dysfunction in obesity has been widely recognized. However, the specific impact of inflammation on iron homeostasis during human adipogenesis and in adipocytes remains poorly understood. In this study, we investigated the effects of bacterial lipopolysaccharide (LPS) on iron homeostasis during human adipocyte differentiation, in fully differentiated adipocytes, and in human adipose tissue. We found that LPS-induced inflammation hindered adipogenesis and led to a gene expression profile indicative of intracellular iron accumulation. This was accompanied by increased expression of iron importers (TFRC and SLC11A2), markers of intracellular iron accumulation (FTH, CYBA, FTL, and LCN2), and decreased expression of iron exporter-related genes (SLC40A1), concomitant with elevated intracellular iron levels. Mechanistically, RNA-seq analysis and gene knockdown experiments revealed the significant involvement of iron importers SLC39A14, SLC39A8, and STEAP4 in LPS-induced intracellular iron accumulation in human adipocytes. Notably, markers of LPS signaling pathway-related inflammation were also associated with a gene expression pattern indicative of intracellular iron accumulation in human adipose tissue, corroborating the link between LPS-induced inflammation and iron accumulation at the tissue level. In conclusion, our findings demonstrate that induction of adipocyte inflammation disrupts iron homeostasis, resulting in adipocyte iron overload.

Stimulation of Potent Humoral and Cellular Immunity via Synthetic Dual-Antigen MVA-Based COVID-19 Vaccine COH04S1 in Cancer Patients Post Hematopoietic Cell Transplantation and Cellular Therapy.

Hematopoietic cell transplantation (HCT) and chimeric antigen receptor (CAR)-T cell patients are immunocompromised, remain at high risk following SARS-CoV-2 infection, and are less likely than immunocompetent individuals to respond to vaccination. As part of the safety lead-in portion of a phase 2 clinical trial in patients post HCT/CAR-T for hematological malignancies (HM), we tested the immunogenicity of the synthetic modified vaccinia Ankara-based COVID-19 vaccine COH04S1 co-expressing spike (S) and nucleocapsid (N) antigens. Thirteen patients were vaccinated 3-12 months post HCT/CAR-T with two to four doses of COH04S1. SARS-CoV-2 antigen-specific humoral and cellular immune responses, including neutralizing antibodies to ancestral virus and variants of concern (VOC), were measured up to six months post vaccination and compared to immune responses in historical cohorts of naïve healthy volunteers (HV) vaccinated with COH04S1 and naïve healthcare workers (HCW) vaccinated with the FDA-approved mRNA vaccine Comirnaty® (Pfizer, New York, NY, USA). After one or two COH04S1 vaccine doses, HCT/CAR-T recipients showed a significant increase in S- and N-specific binding antibody titers and neutralizing antibodies with potent activity against SARS-CoV-2 ancestral virus and VOC, including the highly immune evasive Omicron XBB.1.5 variant. Furthermore, vaccination with COH04S1 resulted in a significant increase in S- and N-specific T cells, predominantly CD4+ T lymphocytes. Elevated S- and N-specific immune responses continued to persist at six months post vaccination. Furthermore, both humoral and cellular immune responses in COH04S1-vaccinated HCT/CAR-T patients were superior or comparable to those measured in COH04S1-vaccinated HV or Comirnaty®-vaccinated HCW. These results demonstrate robust stimulation of SARS-CoV-2 S- and N-specific immune responses including cross-reactive neutralizing antibodies by COH04S1 in HM patients post HCT/CAR-T, supporting further testing of COH04S1 in immunocompromised populations.

Hypomagnesemia Caused by Chronic Use of Over-the-Counter Proton Pump Inhibitor as a Possible Cause of Supraventricular Tachycardia.

Magnesium is an important co-factor that helps regulates the movement of ions through voltage-mediated channels within myocardial tissues by the membrane sodium-potassium pump, and its deficiency can reduce the pump's activity, leading to partial depolarization and changes in the activity of many potential-dependent membrane channels leading to arrhythmias. In this case report, we are looking to establish the direct relationship between hypomagnesemia caused by proton pump inhibitors (PPIs), which could lead to cardiac arrhythmias. Here, we present a 45-year-old Hispanic female, with a known past medical history of supraventricular tachycardia (SVT), hiatal hernia on proton pump inhibitor (PPI), and chronic smoking, who presented to the emergency department complaining of dizziness and palpitations that started two hours prior arrival to the hospital. At triage, the patient was found to have a heart rate of 190 beats per minute (bpm), and an electrocardiogram (EKG) revealed supraventricular tachycardia with a heart rate of 185 bpm. During the review of this case, no other confounding factors besides hypomagnesemia were noted, leaving this one to be the most likely cause of the arrhythmia. Patients on long-term PPI therapy are at higher risk of developing hypomagnesemia, which could lead to cardiac arrhythmia.

Impaired Plakophilin-2 in obesity breaks cell cycle dynamics to breed adipocyte senescence.

Plakophilin-2 (PKP2) is a key component of desmosomes, which, when defective, is known to promote the fibro-fatty infiltration of heart muscle. Less attention has been given to its role in adipose tissue. We report here that levels of PKP2 steadily increase during fat cell differentiation, and are compromised if adipocytes are exposed to a pro-inflammatory milieu. Accordingly, expression of PKP2 in subcutaneous adipose tissue diminishes in patients with obesity, and normalizes upon mild-to-intense weight loss. We further show defective PKP2 in adipocytes to break cell cycle dynamics and yield premature senescence, a key rheostat for stress-induced adipose tissue dysfunction. Conversely, restoring PKP2 in inflamed adipocytes rewires E2F signaling towards the re-activation of cell cycle and decreased senescence. Our findings connect the expression of PKP2 in fat cells to the physiopathology of obesity, as well as uncover a previously unknown defect in cell cycle and adipocyte senescence due to impaired PKP2.

microRNAs signature in relapse metastasis and de novo metastasis of breast cancer. A systematic review.

miRNAs have been widely identified as important players in cancer development and progression. Metastasis in breast cancer can occur as relapse of a treated primary tumour or at the time of diagnosis of the tumour. The aim of this review is to show if both metastasis are different molecular entities characterised by different miRNA signatures that could be studied as specific biomarkers for each entity. For this, we systematically searched the PubMed, Scopus and Web of Science databases. After searching and reviewing the literature, a total of 30 records were included in this review. Results showed a genetic signature including a total of 5 upregulated miRNAs in metastasis compared with early stages. Of them, miR-23b and miR-200c were exclusively present in relapse metastasis. Finally, we proposed a molecular signature for future studies that can be used as a complementary tool at clinical trials for the diagnosis and characterization of metastasis.

Functional SARS-CoV-2-specific T cells of donor origin in allogeneic stem cell transplant recipients of a T-cell-replete infusion: A prospective observational study.

In the current post-pandemic era, recipients of an allogeneic hematopoietic stem cell transplant (HCT) deserve special attention. In these vulnerable patients, vaccine effectiveness is reduced by post-transplant immune-suppressive therapy; consequently, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) disease (COVID-19) is often associated with elevated morbidity and mortality. Characterizing SARS-CoV-2 adaptive immunity transfer from immune donors to HCT recipients in the context of immunosuppression will help identify optimal timing and vaccination strategies that can provide adequate protection to HCT recipients against infection with evolving SARS-CoV-2 variants. We performed a prospective observational study (NCT04666025 at ClinicalTrials.gov) to longitudinally monitor the transfer of SARS-CoV-2-specific antiviral immunity from HCT donors, who were either vaccinated or had a history of COVID-19, to their recipients via T-cell replete graft. Levels, function, and quality of SARS-CoV-2-specific immune responses were longitudinally analyzed up to 6 months post-HCT in 14 matched unrelated donor/recipients and four haploidentical donor/recipient pairs. A markedly skewed donor-derived SARS-CoV-2 CD4 T-cell response was measurable in 15 (83%) recipients. It showed a polarized Th1 functional profile, with the prevalence of central memory phenotype subsets. SARS-CoV-2-specific IFN-γ was detectable throughout the observation period, including early post-transplant (day +30). Functionally experienced SARS-CoV-2 Th1-type T cells promptly expanded in two recipients at the time of post-HCT vaccination and in two others who were infected and survived post-transplant COVID-19 infection. Our data suggest that donor-derived SARS-CoV-2 T-cell responses are functional in immunosuppressed recipients and may play a critical role in post-HCT vaccine response and protection from the fatal disease. Clinical trial registration: clinicaltrials.gov, identifier NCT04666025.

Microfluidic Platform Integrated with Carbon Nanofibers-Decorated Gold Nanoporous Sensing Device for Serum PSA Quantification.

Prostate cancer is a disease with a high incidence and mortality rate in men worldwide. Serum prostate-specific antigens (PSA) are the main circulating biomarker for this disease in clinical practices. In this work, we present a portable and reusable microfluidic device for PSA quantification. This device comprises a polymethyl methacrylate microfluidic platform coupled with electrochemical detection. The platinum working microelectrode was positioned in the outflow region of the microchannel and was modified with carbon nanofibers (CNF)-decorated gold nanoporous (GNP) structures by the dynamic hydrogen bubble template method, through the simultaneous electrodeposition of metal precursors in the presence of CNF. CNF/GNP structures exhibit attractive properties, such as a large surface to volume ratio, which increases the antibody's immobilization capacity and the electroactive area. CNFs/GNP structures were characterized by scanning electron microscopy, energy dispersive spectrometry, and cyclic voltammetry. Anti-PSA antibodies and HRP were employed for the immune-electrochemical reaction. The detection limit for the device was 5 pg mL-1, with a linear range from 0.01 to 50 ng mL-1. The coefficients of variation within and between assays were lower than 4.40%, and 6.15%, respectively. Additionally, its clinical performance was tested in serum from 30 prostate cancer patients. This novel device was a sensitive, selective, portable, and reusable tool for the serological diagnosis and monitoring of prostate cancer.

Grupos reflexivos com estudantes de medicina da liga de saúde mental como estratégia de mudanças / Reflexive groups with medical students from the mental health league as a strategy for change

Resumo O trabalho apresenta os resultados de uma pesquisa qualitativa realizada com estudantes de medicina de uma Liga de Saúde Mental e Psiquiatria (LASMP). Teve como objetivos sensibilizá-los para perceber a si mesmos como pessoas e instrumentalizá-los com outras racionalidades distintas das formas de pensamento biomédicas. Os grupos reflexivos, por meio do círculo de cultura, ofereceram espaço de livre circulação da palavra, tempo para reflexões e compartilhamento de experiências cotidianas vividas em plena formação. Configuraram-se como estratégia de mudança e um despertar para repensar modelos de saúde mais voltados para o cuidado do que para doenças. A observação participante permitiu descortinar, por meio das narrativas, particularidades das experiências, dos discursos e da cultura do próprio grupo. As análises foram realizadas pelo método da reflexividade (Bourdieu, 2001; 2004), por permitir o aprofundamento sistemático dos conteúdos das narrativas. Sem pretensão de síntese, o percurso reflexivo sobre as narrativas partiu dos pressupostos do pensamento e das ações para chegar aos sentidos construídos e partilhados. Ofereceram possibilidades de transformação do modo de ver o mundo do trabalho, a si mesmos e as pessoas a sua volta; de mudança na compreensão da saúde mental para além do plano individual.

Abstract This paper set out to present the outcomes of qualitative research conducted with medical students of a Mental Health and Psychiatry League (LASMP). Its objectives were to sensitize them to perceive themselves as people and provide them with other rationales different from biomedical ways of thinking. The reflexive groups, within the culture circle, provided an opportunity for an exchange of ideas, time for reflection and sharing of fully formed daily experiences. They were configured as a strategy of change and awakening to rethink models of health more focused on healthcare than on diseases. Participant observation enabled revealing, through the narratives, particularities of the experiences, discourses and culture of the group itself. The analyses were carried out using the reflexivity method (Bourdieu, 2001; 2004), as it permits the systematic deepening of the contents of the narratives. Without any pretension of synthesis, the reflexive course on the narratives started from the assumptions of thought and actions to arrive at the constructed and shared meanings. They offered possibilities of transforming the way of perceiving the world of work, themselves, and the people around them; of changing the understanding of mental health beyond the individual level.

Cardiorespiratory fitness and targeted proteomics involved in brain and cardiovascular health in children with overweight/obesity.

Cardiorespiratory fitness (CRF) is inversely associated with cardiovascular disease (CVD) risk factors and brain health impairments. However, the molecular mechanisms linking CRF to health in children are poorly understood. We aimed to examine protein levels related to brain health and CVD in plasma of fit compared to unfit children with overweight/obesity (OW/OB). Eighty-seven children with OW/OB (10.08 ± 1.1 years, 59% boys) from the ActiveBrains project were included. CRF was measured by performing a treadmill test, and children were categorized into fit or unfit. Targeted proteomics in plasma was performed using Olink's proximity extension assay technology of Neurology panel in the whole sample and of Cardiovascular panel in a subsample. Sixteen proteins (PLXNB3, sFRP3, CLEC1B, RSPO1, Gal8, CLEC10A, GCP5, MDGA1, CTSC, LAT, IL4RA, PRSS27, CXCL1, Gal9, MERTK, and GT) were differentially expressed between fit and unfit children with OW/OB after adjusting for sex, maturational status, and body mass index. However, statistically significant differences disappeared after applying FDR correction. Potential candidate proteins related to CRF levels in children with OW/OB were detected, being involved in several biological processes such as neurogenesis, immune/inflammatory response, signal transduction, platelet activation. Nevertheless, these preliminary findings should be confirmed or contrasted in future studies using larger sample sizes, longitudinal and experimental designs.HighlightsThe molecular mechanisms underlying the link of cardiorespiratory fitness (CRF) with cardiovascular and brain health in children with overweight/obesity (OW/OB) are poorly understood.Targeted proteomic analysis revealed differentially expressed proteins (PLXNB3, sFRP3, CLEC1B, RSPO1, Gal8, CLEC10A, GCP5, MDGA1, CTSC, LAT, IL4RA, PRSS27, CXCL1, Gal9, MERTK, and GT) in plasma of "Fit" compared to "Unfit" children with OW/OB. These proteins are involved in several biological processes such as immune/inflammatory response, neurogenesis, signal transduction, and cellular metabolic process.Longitudinal and experimental studies are warranted to reveal how improvements in CRF are related to changes in circulating levels of the abovementioned proteins and how they might reduce cardiovascular diseases risk factors and brain health impairments later in life.

Neurotrophic factors and brain health in children with overweight and obesity: The role of cardiorespiratory fitness.

ABSTRACTNeurotrophic factors and cardiorespiratory fitness are both considered important in developmental trajectories but their link to brain health remains poorly understood. The aims of the study were to examine whether levels of plasma-derived neurotrophic factors were associated with brain health indicators in children with overweight or obesity; and to test whether these associations were moderated by cardiorespiratory fitness. 100 children (41% girls) were included in this analysis. Plasma levels of brain-derived neurotrophic factor, insulin-like growth factor-1, vascular endothelial growth factor A, and epidermal growth factor were determined by XMap technology. Academic performance and executive function were assessed using validated neuropsychological tests. Hippocampal volume was measured using magnetic resonance imaging. Cardiorespiratory fitness was assessed using the 20-m Shuttle Run Test. Insulin-like growth factor-1 was positively associated with cognitive flexibility. Stratified analyses by fitness categories (i.e. unfit vs. fit) showed that brain-derived neurotrophic factor was positively associated with right posterior hippocampal volume in fit children, and epidermal growth factor was negatively associated with right hippocampal, and right anterior hippocampal volumes in their unfit peers, with a moderating role of cardiorespiratory fitness in these associations. However, all these significant associations disappeared after correction for multiple comparisons. The association between neurotrophic factors and brain health indicators in children with overweight/obesity was neither strong nor consistent. These results could help enhance our understanding of determinants of brain health in children with overweight/obesity.HighlightsThis study provides novel findings on the associations between neurotrophic factors and a wide range of brain health indicators in children.This study additionally explored the role of cardiorespiratory fitness in these associations.The association between neurotrophic factors and brain health in children with overweight/obesity was neither strong nor consistent.Cardiorespiratory fitness moderated the associations of brain-derived neurotrophic factor and epidermal growth factor with right hippocampal volume.

Microfluidic amperometric immunosensor based on porous nanomaterial towards claudin7 determination for colorectal cancer diagnosis.

In this work, we present a microfluidic amperometric immunosensor for cancer biomarker claudin7 (CLD7) determination in circulating extracellular vesicles (EVs) as well as its validation in colorectal cancer (CC) patients. The device is based on synthetized nanosized MIL-125-NH2 particles, covalently anchored to the central channel of the microfluidic immunosensor. This nanomaterial was employed as efficient platform for anti-CLD7 monoclonal antibodies immobilization for specifically recognize and capture CLD7 in EVs samples. Afterwards, the amount of this trapped CLD7 was quantified by HRP-conjugated anti-CLD7-antibody. HRP reacted with its enzymatic substrate in a redox process which resulted in the appearance of a current whose magnitude was directly proportional to the level of CLD7 in the sample. This immunosensor, under optimum conditions, gave the limit of detection for CLD7 of 0.1 pg mL-1, with a wide linear range from 2 to 1000 pg mL-1. The results reported herein open up the use of porous open framework platforms for sensing applications for biomedicine and diagnosis.
