RESUMO

BACKGROUND: Psychosocial evaluation for transplant suitability is required by the Centers for Medicare and Medicaid Services (CMS) as a condition of participation for transplant programs. There are no regulations regarding follow-up reassessment for transplant readiness after waitlisting. OBJECTIVES: An evidence-based pilot project was developed and implemented to evaluate the feasibility of psychosocial readiness assessments for waitlisted heart transplantation candidates. The primary aim was to test the feasibility of these assessments in practice from a patient and programmatic perspective. METHODS: During a 12-week period, waitlisted outpatients underwent one assessment each. Socioeconomic elements of caregiver support, housing, transportation, and insurance coverage status were assessed by simple using "yes/no" questions. To assess mental health needs, the General Anxiety Disorder-7 questionnaire (GAD-7) and the Patient Health Questionnaire-8 (PHQ-8) tools were utilized. Rescheduled readiness visits and no-show rates were measured. A post-implementation Qualtrics survey was administered to measure team member perceptions of feasibility. RESULTS: A total of 57 patients were assessed during the 12-week period. The primary aim of feasibility was achieved with 93 % of visits performed with freedom from rescheduling or patient no-show to the visit. Additionally, 75 % of team members reported the readiness assessments were feasible to complete in practice. CONCLUSIONS: Addressing the non-medical and mental health needs of waitlisted heart transplant patients allows transplant programs to maintain candidates with necessary resources and care. The readiness assessments are feasible in practice and may serve to reduce untoward outcomes in the post-transplant phase by providing targeted care prior to the time of transplant.

RESUMO

OBJECTIVE: Skin burns are associated with the presence of metallic components in transdermal drug delivery systems during Magnetic Resonance Imaging, cardioversion or defibrillation procedures. The aim of the study was to review the presence of metallic components in marketed products of transdermal drug delivery systems in Spain. METHOD: For each presentation, the summary of product characteristics was reviewed. If the information was not provided, manufacturers were contacted. RESULTS: We identified 59 marketed products of transdermal drug delivery systems of 12 different active substances. 59.3% of patches contained metallic components or their presence could not be ruled out. Information regarding the need to remove the patch was only included in 8 summaries of product characteristics (13.6%). A table was elaborated and included the following aspects: product, active substance, manufacturer, need to remove the patch before the exposure to magnetic or electric fields and references. CONCLUSION: More than a half of the patches at the time of the study contained metals or their absence could not be confirmed by the manufacturer. However, this information was only included in 13.6% of summaries of product characteristics.

RESUMO

OBJECTIVES: To develop a cultural and trauma-informed mental health self-management program for immigrant Latina survivors of adverse childhood experiences with depression or anxiety symptoms. METHOD: Guided by Barrera's five-stage process for cultural adaptation, we collaborated with multiple stakeholders including clinical psychologists, community health workers, and Latina immigrant women with a history of adverse childhood experiences and depression or anxiety to transform a chronic disease self-management program to be trauma informed, culturally appropriate, and focus on self-management of depression and anxiety symptoms. RESULTS: Adaptations included translating program materials to Spanish, education on how early life adversity and trauma may impact mental health, virtual delivery, more frequent and shorter sessions, and addition of graphics and written prompts in workbook materials. For the facilitator's manual, culturally relevant vignettes and guidance were added to guide participants through activities and adapt sessions based on participant needs. CONCLUSIONS: Barrera's five-stage process was useful for adapting a program to be both trauma and culturally informed for an underserved population disproportionately affected by trauma and limited access to mental health services. The adaptation demonstrated acceptability with Latina immigrant women and the promise of utilizing unlicensed personnel and technology for increasing the reach of mental health support.

RESUMO

BACKGROUND: Growing evidence suggests that Latina immigrant survivors of adverse childhood experiences (ACEs) are at increased risk for developing and remaining with either depression or anxiety or both symptoms. This study examined the feasibility and acceptability of a telehealth intervention-Cuidándome (quee-DAN-doh-meh, "taking care of myself"). Cuidándome is a 10-week, patient-centered, trauma-informed intervention delivered by a trained facilitator that promotes self-management of depression and anxiety symptoms through improved problem-solving skills and strategies. OBJECTIVE: The aim of this study was to examine the feasibility and acceptability of Cuidándome delivered remotely (via Zoom) with Latina immigrant ACE survivors with either depression or anxiety or both symptoms. We also estimated the effect sizes associated with the intervention on decreasing depression and anxiety symptoms and improving social problem-solving styles. METHODS: We evaluated Cuidándome using a randomized controlled trial design. Latina immigrants (N=47) who had experienced at least 1 ACE and had at least mild depression or anxiety symptoms were randomized to Cuidándome or a comparison group delivered by trained facilitators. We assessed for changes in depression and anxiety symptoms as well as social problem-solving styles at baseline, post intervention, and 3- and 6-month follow-up. RESULTS: Analyses indicated significant decreases over time within both Cuidándome and comparison groups for depression and anxiety symptoms and maladaptive problem-solving. The intervention effect was largest for anxiety; at 6-month follow-up, Cuidándome participants had significantly lower anxiety scores than the comparison group. In addition, we observed a greater average point reduction in depression symptoms at 6 months among Cuidándome participants (5.7 points) than in the comparison group (3.7 points). CONCLUSIONS: A mental health program delivered via Zoom by a trained facilitator was feasible and acceptable to Latina immigrant women and can be beneficial for reducing anxiety and depression symptoms. More research is needed to assess the effectiveness of Cuidándome among a powered sample size of Latina immigrants.

RESUMO

The rise in antifungal resistance and side effects of conventional treatments drive the search for innovative therapies like Photodynamic Therapy (PDT). This study explored the efficacy of PDT mediated by gutiferone, an isolated compound from red propolis, for candidiasis treatment. Multiple evaluation methods were employed, including determining the minimum inhibitory concentration (MIC) via broth microdilution, quantifying biomass using crystal violet detachment, and cell counting through total plate count. PDT mediated by gutiferone was also assessed in five groups of mice, followed by histopathological examination and agar plating of lingual tissue samples. Among the seven Candida species tested, gutiferone displayed efficacy against C. albicans, C. glabrata, and C. tropicalis, with MIC values of 1000 µg/mL. In C. tropicalis biofilms, exposure to gutiferone led to a reduction of 1.61 Log10 CFU/mL. PDT mediated by gutiferone achieved an average reduction of 3.68 Log10 CFU/mL in C. tropicalis biofilm cells, underscoring its potent fungicidal activity. Histopathological analysis revealed fungal structures, such as pseudohyphae and hyphae, in infected groups (G2) and irradiated mice. In contrast, groups treated with gutiferone or subjected to gutiferone-assisted PDT (G5) exhibited only few blastoconidia. Furthermore, CFU/mL assessments in lingual tissue post-treatment demonstrated a significantly lower count (0.30 Log10 CFU/mL) in the G5 group compared to G2 (2.43 Log10 CFU/mL). These findings highlight the potential of PDT mediated by gutiferone as a promising alternative for managing denture stomatitis. Future research and clinical investigations offer the promise of validating its clinical applicability and improving outcomes in the treatment of oral candidiasis.

RESUMO

Alterations in plant metabolism play a key role in the complex plant-pathogen interactions. However, there is still a lack of knowledge about the connection between changes in primary and specialized metabolism and the plant defense against diseases that impact crops. Thus, we aim to study the metabolic reprograming in Brassica oleracea plants upon infection by Xanthomonas campestris pv. campestris (Xcc). To accomplish this, we utilized a combination of untargeted and targeted metabolomics, through UPLC-Q-TOF-MS/MS and 1H-NMR, in two crop lines differing in resistance that were evaluated at two- and four-week intervals following inoculation (T1 and T2, respectively). Besides, to depict the physiological status of the plant during infection, enzymatic activities related to the carbohydrate pathway and oxidative stress were studied. Our results revealed different temporal dynamics in the responses of the susceptible vs. resistant crops lines. Resistant B. oleracea line suppresses carbohydrate metabolism contributing to limit nutrient supplies to the bacterium and prioritizes the induction of defensive compounds such as indolic glucosinolates, salicylic acid, phenylpropanoids and phytoalexins precursors at early infection stages. In contrast, the susceptible line invests in carbohydrate metabolism, including enzymatic activities related to the hexoses turnover, and activates defense signaling related to reactive oxygen species. Thus, each line triggers a different metabolic strategy that will affect how the plant overcomes the disease in terms of resistance and growth. This work provides first insights of a fine-tuned metabolic regulation during Xcc infection in B. oleracea that will contribute to develop new strategies for plant disease management.

RESUMO

Mother's milk contains a unique microbiome that plays a relevant role in offspring health. We hypothesize that maternal malnutrition during lactation might impact the microbial composition of milk and affect adequate offspring gut colonization, increasing the risk for later onset diseases. Then, Wistar rats were fed ad libitum (Control, C) food restriction (Undernourished, U) during gestation and lactation. After birth, offspring feces and milk stomach content were collected at lactating day (L)4, L14 and L18. The V3-V4 region of the bacterial 16S rRNA gene was sequenced to characterize bacterial communities. An analysis of beta diversity revealed significant disparities in microbial composition between groups of diet at L4 and L18 in both milk, and fecal samples. In total, 24 phyla were identified in milk and 18 were identified in feces, with Firmicutes, Proteobacteria, Actinobacteroidota and Bacteroidota collectively representing 96.1% and 97.4% of those identified, respectively. A higher abundance of Pasteurellaceae and Porphyromonas at L4, and of Gemella and Enterococcus at L18 were registered in milk samples from the U group. Lactobacillus was also significantly more abundant in fecal samples of the U group at L4. These microbial changes compromised the number and variety of milk-feces or feces-feces bacterial correlations. Moreover, increased offspring gut permeability and an altered expression of goblet cell markers TFF3 and KLF3 were observed in U pups. Our results suggest that altered microbial communication between mother and offspring through breastfeeding may explain, in part, the detrimental consequences of maternal malnutrition on offspring programming.

RESUMO

A theoretical analysis of free Gibbs Energy and NMR 1H 13C chemical shifts of the effect of introduce methyl groups on diphenyl rings, to produce different isomers of (E)-1-(α,Ꞵ-dimethylbenzylidene)-2,2-diphenylhydrazine, is presented. IR vibrational frequencies, Mulliken charges, molecular electrostatic potential (MEP), Gibbs free energy (G) and 1H- and 13C-NMR chemical shifts were obtained by theoretical calculations. In this analysis it was found that the position of the methyl group affects the values of the 1H- and 13C-NMR chemical shifts and the ∆G and ∆H thermodynamic properties of formation and reaction, these properties vary with the same trend, for the isomers studied. Gibbs free energy calculations show that the theoretical (E)-1-(3,4-Dimethylbenzylidene)-2,2-diphenylhydrazine isomer is the most stable, which explains the success of the experimental synthesis of this compound among the other isomers. For this molecule, the C of the HC=N group is the most nucleophilic and the H is the least acidic. The 1H-NMR chemical shifts of protons show a strong correlation with the C=N distance. It was also observed that methyl affects the ν(C=N) frequencies, the C=N distance increases when the inductive effect of the methyl groups is in the structure.

RESUMO

BACKGROUND: The use of molecular biomarkers for COVID-19 remains unconclusive. The application of a molecular biomarker in combination with clinical ones that could help classifying aggressive patients in first steps of the disease could help clinician and sanitary system a better management of the disease. Here we characterize the role of ACE2, AR, MX1, ERG, ETV5 and TMPRSS2 for trying a better classification of COVID-19 through knowledge of the disease mechanisms. METHODS: A total of 329 blood samples were genotyped in ACE2, MX1 and TMPRSS2. RNA analyses were also performed from 258 available samples using quantitative polymerase chain reaction for genes: ERG, ETV5, AR, MX1, ACE2, and TMPRSS2. Moreover, in silico analysis variant effect predictor, ClinVar, IPA, DAVID, GTEx, STRING and miRDB database was also performed. Clinical and demographic data were recruited from all participants following WHO classification criteria. RESULTS: We confirm the use of ferritin (p < 0.001), D-dimer (p < 0.010), CRP (p < 0.001) and LDH (p < 0.001) as markers for distinguishing mild and severe cohorts. Expression studies showed that MX1 and AR are significantly higher expressed in mild vs severe patients (p < 0.05). ACE2 and TMPRSS2 are involved in the same molecular process of membrane fusion (p = 4.4 × 10-3), acting as proteases (p = 0.047). CONCLUSIONS: In addition to the key role of TMPSRSS2, we reported for the first time that higher expression levels of AR are related with a decreased risk of severe COVID-19 disease in females. Moreover, functional analysis demonstrates that ACE2, MX1 and TMPRSS2 are relevant markers in this disease.

RESUMO

BACKGROUND: Despite recent well-established kidney tropism of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), usually presenting as acute kidney injury (AKI), there are few published cases with SARS-CoV-2-related tubulointerstitial nephritis (TIN). We report an adolescent with TIN and delayed association with uveitis (TINU syndrome), where SARS-CoV-2 spike protein was identified in kidney biopsy. CASE-DIAGNOSIS/TREATMENT: A 12-year-old girl was assessed for a mild elevation of serum creatinine detected during the evaluation of systemic manifestations including asthenia, anorexia, abdominal pain, vomiting, and weight loss. Data of incomplete proximal tubular dysfunction (hypophosphatemia and hypouricemia with inappropriate urinary losses, low molecular weight proteinuria, and glucosuria) were also associated. Symptoms had initiated after a febrile respiratory infection with no known infectious cause. After 8 weeks, the patient tested positive in PCR for SARS-CoV-2 (Omicron variant). A subsequent percutaneous kidney biopsy revealed TIN and immunofluorescence staining with confocal microscopy detected the presence of SARS-CoV-2 protein S within the kidney interstitium. Steroid therapy was started with gradual tapering. Ten months after onset of clinical manifestations, as serum creatinine remained slightly elevated and kidney ultrasound showed mild bilateral parenchymal cortical thinning, a second percutaneous kidney biopsy was performed, without demonstrating acute inflammation or chronic changes, but SARS-CoV-2 protein S within the kidney tissue was again detected. At that moment, simultaneous routine ophthalmological examination revealed an asymptomatic bilateral anterior uveitis. CONCLUSIONS: We present a patient who was found to have SARS-CoV-2 in kidney tissue several weeks following onset of TINU syndrome. Although simultaneous infection by SARS-CoV-2 could not be demonstrated at onset of symptoms, since no other etiological cause was identified, we hypothesize that SARS-CoV-2 might have been involved in triggering the patient's illness.

RESUMO

Purpose: We carried out a histological characterization analysis of the stromal layer of human heterotypic cornea substitutes generated with extra-corneal cells to determine their putative usefulness in tissue engineering. Methods: Human bioartificial corneas were generated using nanostructured fibrin-agarose biomaterials with corneal stromal cells immersed within. To generate heterotypical corneas, umbilical cord Wharton's jelly stem cells (HWJSC) were cultured on the surface of the stromal substitutes to obtain an epithelial-like layer. These bioartificial corneas were compared with control native human corneas and with orthotypical corneas generated with human corneal epithelial cells on top of the stromal substitute. Both the corneal stroma and the basement membrane were analyzed using histological, histochemical and immunohistochemical methods in samples kept in culture and grafted in vivo for 12 months in the rabbit cornea. Results: Our results showed that the stroma of the bioartificial corneas kept ex vivo showed very low levels of fibrillar and non-fibrillar components of the tissue extracellular matrix. However, in vivo implantation resulted in a significant increase of the contents of collagen, proteoglycans, decorin, keratocan and lumican in the corneal stroma, showing higher levels of maturation and spatial organization of these components. Heterotypical corneas grafted in vivo for 12 months showed significantly higher contents of collagen fibers, proteoglycans and keratocan. When the basement membrane was analyzed, we found that all corneas grafted in vivo showed intense PAS signal and higher contents of nidogen-1, although the levels found in human native corneas was not reached, and a rudimentary basement membrane was observed using transmission electron microscopy. At the epithelial level, HWJSC used to generate an epithelial-like layer in ex vivo corneas were mostly negative for p63, whereas orthotypical corneas and heterotypical corneas grafted in vivo were positive. Conclusion: These results support the possibility of generating bioengineered artificial corneas using non-corneal HWJSC. Although heterotypical corneas were not completely biomimetic to the native human corneas, especially ex vivo, in vivo grafted corneas demonstrated to be highly biocompatible, and the animal cornea became properly differentiated at the stroma and basement membrane compartments. These findings open the door to the future clinical use of these bioartificial corneas.

RESUMO

Introduction: Violence against women (VAW) is a worldwide social and health problem of epidemic proportions. This violence is preventable, and bystander programs are one of the possible preventative strategies. The main purpose of this research was to develop a tool that, by applying a contrastive methodology for its application in different forms of violence (forms of gender-based violence, such as intimate partner VAW, sexual harassment at work, and street harassment, and common violence, such as a robbery), would allow measuring the probability of occurrence of bystander response in the face of these types of violence with good evidence of content validity. Method: Firstly (Study 1), an initial version of a measure tool, the Questionnaire of Intention to Help in VAW Cases (QIHVC), was developed; secondly (Study 2), a Delphi (modified) study was carried out to obtain valid, content-based evidence; and finally (Study 3), a pilot study was carried out to evaluate the appropriate functioning of the QIHVC and, if required, to make any necessary adjustments. Results and discussion: The main result is the development of a set of case scenarios and a questionnaire related to its content which constitutes the QIHVC and, in its initial approximation, seems to constitute an adequate and sensible tool to capture the differences between the characterizations of common violence and VAW and in the possible response of bystanders in the face of such violence.

RESUMO

BACKGROUND: Venous ulcers usually present a torpid evolution with a negative impact on patients' quality of life. In primary care, they account for 2.5% of nursing consultations and their treatment represents high costs for national health systems. These patients usually have a low level of physical activity, with muscle pump dysfunction of the lower limbs, which may improve with increased physical activity. The purpose of this study is to analyse the effectiveness of a structured intervention involving physical activity and exercise (Active Legs) as an adjuvant treatment in improving healing of chronic venous ulcers at 3 months follow-up. METHODS: A randomized, multicentre clinical trial. A total of 224 individuals receiving primary nursing care with a diagnosis of venous ulcer, with a diameter of 1 cm or greater and an ankle-brachial index between 0.8 and 1.3, able to comply with the study requirements and consenting to participate, will be sequentially included (112 per group). Both groups will receive the standard treatment in primary care, with cleansing, debridement and healing in a moist environment together with multilayer compression therapy. The intervention group will also receive a structured educational intervention involving lower limb physical exercise and daily ambulation guidelines. The primary response variables will be complete healing -understood as complete and sustained epithelialisation for at least 2 weeks- and time to healing. The secondary variables will be degree of healing, ulcer area, quality of life, pain and variables related to the healing process, prognosis, and recurrences. Sociodemographic variables, adherence to treatment and satisfaction variables will also be recorded. Data will be collected at baseline, at 3 months and at 6 months follow-up. Survival analysis (Kaplan-Meier and Cox) will be performed to measure primary effectiveness. Intention-to-treat analysis. DISCUSSION: If the intervention is effective, a cost-effectiveness analysis could be conducted and implemented as an additional intervention in the usual venous ulcer treatment in primary care.

RESUMO

BACKGROUND: A protective hepatitis B virus (HBV) vaccine has been available for four decades. Universal HBV vaccination of infants is recommended by the WHO since the 1990s. Furthermore, HBV immunization is advised for all adults with high-risk behaviours and no seroprotection. However, HBV vaccine coverage remains globally suboptimal. The advent of new more efficacious trivalent HBV vaccines has renewed the interest in HBV vaccination. At present, the extent of current HBV susceptibility in adults remains unknown in Spain. METHODS: HBV serological markers were assessed on a large and representative sample of adults in Spain, including blood donors and individuals belonging to high-risk groups. Serum HBsAg, anti-HBc and anti-HBs were tested in specimens collected during the last couple of years. RESULTS: From 13 859 consecutive adults tested at seven cities across the Spanish geography, overall 166 (1.2%) had positive HBsAg. Past HBV infection was recognized in 14% and prior vaccine immunization in 24%. Unexpectedly, 37% of blood donors and 63% of persons belonging to high-risk groups had no serum HBV markers and therefore were potentially HBV susceptible. CONCLUSION: Roughly 60% of adults living in Spain seem to be HBV susceptible. Waning immunity might be more common than expected. Hence, HBV serological testing should be performed at least once in all adults regardless of risk exposures. HBV vaccine full courses or boosters should be administered to all adults lacking serological evidence of HBV protection.
