RESUMEN

ABSTRACT: Granulomatous slack skin (GSS) is a rare subtype of mycosis fungoides, and few cases have been known to spread to the blood, lymph nodes, or viscera. We present a case with early dissemination to the lung. A 27-year-old woman, previously healthy, presented with scattered disseminated scaly patches, associated with vulvar and intergluteal firm swelling and groin-skin induration for 1 year. She also reported mild fatigue and breathlessness on moderate exertion. The patient underwent blood tests, skin biopsies, and computed tomography scan. The skin biopsy showed a mildly atypical T-cell lymphoid infiltrate involving the dermis/hypodermis, with focal epidermotropism, associated with a granulomatous infiltrate and elastophagocytosis. The computed tomography scan revealed bilateral ground-glass lung nodular opacities. Positron emission tomography showed an increased signal in the skin and subcutis around the buttocks, inguinal and mediastinal lymph nodes, and lungs. The lung biopsy confirmed a dense T-cell infiltrate with numerous multinucleated giant cells. Subsequently, esophageal involvement was also observed following biopsy. Molecular analyses demonstrated identical T-cell clones in the skin and lung. After 6 cycles of chemotherapy/localized external radiotherapy, the patient had a partial skin response and stable lung disease. A preferred diagnosis of GSS with systemic spread was made based on clinical/histologic/molecular findings, after considering granulomatous mycosis fungoides and peripheral T-cell lymphoma, not otherwise specified. This case highlights the frequent diagnostic difficulty in distinguishing GSS from an inflammatory granulomatous dermatitis. Pulmonary and esophageal involvements are rare in GSS, and the simultaneous presentation of characteristic cutaneous GSS with systemic disease poses an additional classification challenge.

RESUMEN

PURPOSE: The monitoring of training loads and quantification of physical performance are common practices in youth soccer academies to support coaches in prescribing and programming training for individuals. The interaction between training load and physical performance is unknown during a preseason period in youth soccer players. The current study assessed changes in training load and physical assessments across a 4-week preseason period. The relationship between physical performance and match playing time in youth male soccer players was also investigated. METHODS: The training loads of 25 professional youth academy male soccer players were monitored throughout a 4-week preseason period. Assessments of power, agility, speed, and aerobic capacity were undertaken in the first training session. Session ratings of perceived exertion (sRPE) and well-being questionnaires were collected during all training sessions and preseason matches. Playing time during subsequent competitive matches was recorded. RESULTS: T test and 30-m-sprint assessments, conducted on the first day of preseason, were predictors of sRPE throughout preseason (t test χ2/df = 2.895, poor adjustment; 30-m sprint χ2/df = 1.608, good adjustment). YoYo Test performance was related with changes in perceived fatigue (χ2/df = 0.534, very good adjustment). Faster players reported higher values of sRPE, and players with higher aerobic capacity reported higher levels of fatigue across preseason. Well-being, perceived fatigue and soreness, and sRPE decreased across preseason. Greater match durations were related to higher levels of fatigue during preseason (P < .05). CONCLUSION: The current study highlights the relationship between training load, physical assessments, and playing time. Coaches and practitioners can use physical test data at the start of preseason as an indication of players that report higher sRPE, perceived fatigue, and reduced well-being across preseason, supporting decisions around individualized training prescriptions.

RESUMEN

The human immunodeficiency virus (HIV)-encoded accessory protein Nef enhances pathogenicity by reducing major histocompatibility complex I (MHC-I) cell surface expression, protecting HIV-infected cells from immune recognition. Nef-dependent downmodulation of MHC-I can be reversed by subnanomolar concentrations of concanamycin A (1), a well-known inhibitor of vacuolar ATPase, at concentrations below those that interfere with lysosomal acidification or degradation. We conducted a structure-activity relationship study that assessed 76 compounds for Nef inhibition, 24 and 72 h viability, and lysosomal neutralization in Nef-expressing primary T cells. This analysis demonstrated that the most potent compounds were natural concanamycins and their derivatives. Comparison against a set of new, semisynthetic concanamycins revealed that substituents at C-8 and acylation of C-9 significantly affected Nef potency, target cell viability, and lysosomal neutralization. These findings provide important progress toward understanding the mechanism of action of these compounds and the identification of an advanced lead anti-HIV Nef inhibitory compound.

RESUMEN

Background: The asymptomatic at-risk phase might be the optimal time-window to establish clinically meaningful endpoints in Alzheimer's disease (AD). Objective: We investigated whether, compared with the Free and Cued Selective Reminding Test (FCSRT), the Memory Binding Test (MBT) can anticipate the diagnosis of emergent subtle episodic memory (EM) deficits to an at-risk phase. Methods: Five-year longitudinal FCSRT and MBT scores from 45 individuals matched for age, education, and gender, were divided into 3 groups of 15 subjects: Aß-/controls, Aß+/stable, and Aß+/progressors (preclinical-AD). The MBT adds an associative memory component (binding), particularly sensitive to subtle EM decline. Results: In the MBT, EM decline started in the Aß+/progressors (preclinical-AD) up to 4 years prior to diagnosis in delayed free recall (FR), followed by decline in binding-associated scores 1 year later. Conversely, in the FCSRT, EM-decline began later, up to 3 years prior to diagnosis, in the same group on both immediate and delayed versions of FR, while on total recall (TR) and intrusions decline started only 1 year prior to diagnosis. Conclusions: The MBT seems more sensitive than the FCSRT for early EM-decline detection, regarding the year of diagnosis and the number of scores showing AD-linked EM deficits (associated with the AD-characteristic amnesic hippocampal syndrome). Considering the MBT as a detection tool of early subtle EM-decline in an asymptomatic at-risk phase, and the FCSRT as a classification tool of stages of EM-decline from a preclinical phase, these tests ought to potentially become complementary diagnostic tools that can foster therapies to delay cognitive decline. Clinical trial registration title: Electrophysiological markers of the progression to clinical Alzheimer disease in asymptomatic at-risk individuals: a longitudinal event-related potential study of episodic memory in the INSIGHT pre-AD cohort (acronym: ePARAD).

RESUMEN

Introduction: Gastrostomies can be performed percutaneously by interventional radiology (PRG) or endoscopy (PEG). Methods: Retrospective analysis of patients with advanced cancer who underwent a gastrostomy in 2017 in an oncology center. Results: In 2017, 164 patients underwent gastrostomies, and 137 (84%) were male. The median age was 60 years (range: 38-91). The predominant Eastern Cooperative Oncology Group (ECOG) performance status stage was 1, with 73 (45%) patients. Head and neck cancer was the most common diagnosis, with 127 (77%) cases. The most frequent reason for performing a gastrostomy was dysphagia, 132 (81%). Most gastrostomies were PEG, 121 (74%), followed by PRG, 41 (25%), and surgery, 2 (1%). Early complications occurred in 86 (52%) patients, and the most frequent of them were local pain in 69 (80%) patients and minor local bleeding in 13 (15%). Late complications occurred in 90 (55%) patients, and the most frequent was also local pain in 57 (63%) patients, followed by local infection in 8 (9%), tube extrusion in 7 (8%), and stomal leakage in 7 (8%). In the multivariable analysis, the factors associated with survival were lymph node metastases and the ECOG performance status. Until June 30th, 2022, 123 (75%) patients had died, and 41 (25%) were still alive. Conclusion: Gastrostomies were performed predominantly in ECOG performance stage 1 patients with head and neck cancer and symptoms of dysphagia, and PEG was the most common procedure.

RESUMEN

Coronavirus disease 2019 (COVID-19) is an infectious disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), leading to pneumonia and acute respiratory distress syndrome. The COVID-19 pandemic had a major impact on the stock of blood banks worldwide. This study aims to assess the prevalence of COVID-19 in a population of whole blood donors and analyze the possible association between blood group and susceptibility to the disease and the impact of adopting preventive measures against SARS-CoV-2 infection. Material and methods: This retrospective study included all whole blood donors from a Portuguese hospital between July and September 2021. A self-assessment questionnaire was used to collect data on COVID-19 infection, vaccination, and preventive measures. Statistical analysis was performed using Chi-square and Mann-Whitney U tests. Results: The prevalence of COVID-19 in the donor population was 11.96% (n = 97), with only 2 cases of serious illness requiring hospitalization. No association was found between blood group and disease susceptibility. Older men were less likely to adopt preventive measures. The vaccination rate was high, with 84.26% of donors having received at least one dose of the vaccine. Seven donors declined COVID-19 vaccination. Preventive measures did not differ based on COVID-19 infection status or vaccination. Discussion: Although there was a higher frequency of COVID-19 in group A donors, the blood group was not associated with susceptibility to infection. The donor population consisted of young individuals without comorbidities, showing a COVID-19 prevalence like the general population and few severe cases. The high vaccination rate and adoption of preventive measures likely contributed to these findings.

RESUMEN

Spontaneous pneumomediastinum is a rare medical condition characterized by the presence of free air in the mediastinum, not preceded by trauma, surgery, or another medical procedure. It predominantly affects young adult males and usually has a benign course, and in most cases, it is not possible to identify the precipitating factor. There are some conditions that predispose to its occurrence, namely those that lead to an increase in intrapleural pressure, such as coughing, vomiting, or vigorous exercise. We report a case of a 21-year-old male who presented with acute-onset shortness of breath after an episode of coughing and was found to have mediastinal and subcutaneous emphysema. Clinical, laboratory, and radiological studies did not demonstrate any predisposing factor, and the case was classified as spontaneous pneumomediastinum.

RESUMEN

Leukocytoclastic vasculitis (LCV) is a type of small vessel vasculitis, characterized by a perivascular neutrophilic inflammatory infiltrate with fibrinoid necrosis and fragmentation of nuclei ("leukocytoclasia"). Although up to half of the cases of LCV are idiopathic, infections and drugs are the most common secondary triggers for this condition. We present the case of an 88-year-old woman who developed an erythematous maculopapular rash on both thighs three days after starting gabapentin for neuropathic leg pain, without other associated symptoms. Skin biopsy was compatible with cutaneous vasculitis with a leukocytoclastic pattern. The skin lesions resolved within about 10 days after discontinuing gabapentin, supporting the diagnosis. To our knowledge, there are only four published cases of LCV secondary to gabapentin. This case highlights the importance of being alert for diagnosing drug-related cutaneous manifestations, even if the drug is used in our daily practice and vasculitis is not a common side effect, since discontinuing the suspected agent is crucial to resolve skin lesions and to avoid more serious complications.

RESUMEN

OBJECTIVE: This study aimed to investigate medication management among polymedicated, home-dwelling older adults after discharge from a hospital centre in French-speaking Switzerland and then develop a model to optimise medication management and prevent adverse health outcomes associated with medication-related problems (MRPs). DESIGN: Explanatory, sequential, mixed methods study based on detailed quantitative and qualitative findings reported previously. SETTING: Hospital and community healthcare in the French-speaking part of Switzerland. PARTICIPANTS: The quantitative strand retrospectively examined 3 years of hospital electronic patient records (n=53 690 hospitalisations of inpatients aged 65 years or older) to identify the different profiles of those at risk of 30-day hospital readmission and unplanned nursing home admission. The qualitative strand explored the perspectives of older adults (n=28), their informal caregivers (n=17) and healthcare professionals (n=13) on medication management after hospital discharge. RESULTS: Quantitative results from older adults' profiles, affected by similar patient-related, medication-related and environment-related factors, were enhanced and supported by qualitative findings. The combined findings enabled us to design an interprofessional, collaborative medication management model to prevent MRPs among home-dwelling older adults after hospital discharge. The model comprised four interactive fields of action: listening to polymedicated home-dwelling older adults and their informal caregivers; involving older adults and their informal caregivers in shared, medication-related decision-making; empowering older adults and their informal caregivers for safe medication self-management; optimising collaborative medication management practices. CONCLUSION: By linking the retrospective and prospective findings from our explanatory sequential study involving multiple stakeholders' perspectives, we created a deeper comprehension of the complexities and challenges of safe medication management among polymedicated, home-dwelling older adults after their discharge from hospital. We subsequently designed an innovative, collaborative, patient-centred model for optimising medication management and preventing MRPs in this population.

RESUMEN

Unawareness of memory deficits is an early manifestation in patients with Alzheimer's disease (AD), which often delays diagnosis. This intriguing behavior constitutes a form of anosognosia, whose neural mechanisms remain largely unknown. We hypothesized that anosognosia may depend on a critical synaptic failure in the error-monitoring system, which would prevent AD patients from being aware of their own memory impairment. To investigate, we measured event-related potentials (ERPs) evoked by erroneous responses during a word memory recognition task in two groups of amyloid positive individuals with only subjective memory complaints at study entry: those who progressed to AD within the five-year study period (PROG group), and those who remained cognitively normal (CTRL group). A significant reduction in the amplitude of the positivity error (Pe), an ERP related to error awareness, was observed in the PROG group at the time of AD diagnosis (vs study entry) in intra-group analysis, as well as when compared with the CTRL group in inter-group analysis, based on the last EEG acquisition for all subjects. Importantly, at the time of AD diagnosis, the PROG group exhibited clinical signs of anosognosia, overestimating their cognitive abilities, as evidenced by the discrepancy scores obtained from caregiver/informant vs participant reports on the cognitive subscale of the Healthy Aging Brain Care Monitor. To our knowledge, this is the first study to reveal the emergence of a failure in the error-monitoring system during a word memory recognition task at the early stages of AD. This finding, along with the decline of awareness for cognitive impairment observed in the PROG group, strongly suggests that a synaptic dysfunction in the error-monitoring system may be the critical neural mechanism at the origin of unawareness of deficits in AD.

RESUMEN

AIMS: To describe the perceived barriers to nurses performing physical assessments of patients in rehabilitation wards. Secondarily, to investigate how sociodemographic and professional characteristics influence the use and frequency of physical assessments by nurses and their perceptions of barriers to their practice. DESIGN: A multicentre, cross-sectional, observational study. METHODS: Data were collected from September to November 2020 among nurses working with inpatients in eight rehabilitation care institutions in French-speaking Switzerland. Instruments included the Barriers to Nurses' use of Physical Assessment Scale. RESULTS: Almost half of the 112 nurses who responded reported performing physical assessments regularly. The predominant perceived barriers to performing physical assessments were 'specialty area', 'lack of nursing role models' and 'lack of time and interruptions'. Greater clinical nursing experience in rehabilitation wards and more senior nurse specialist positions were associated with significantly lower use of physical assessment procedures by nurses. CONCLUSION: The present study revealed heterogeneity in the use of physical assessment by nurses practicing in rehabilitation units and highlighted their perceived barriers to this. IMPACT STATEMENT: Most nurses working in rehabilitation care units did not routinely perform physical assessments as part of their daily clinical practice. These results should raise stakeholders' awareness of this fact. Effective interventions to increase the use of physical assessments in nursing practice are to be recommended, including continuing education or hiring enough highly qualified nurses as role models in wards. This will promote quality of care and patient safety in rehabilitation care units. PUBLIC AND PATIENT ENGAGEMENT AND INVOLVEMENT: There was no patient or public involvement in the present study.

RESUMEN

Ageing is frequently associated with multimorbidity and polypharmacy. The present study aimed to identify the current medication management patterns and the profiles of home-dwelling older adults and to find any association with their conditions, including frailty and cognitive impairment. Within the scope of this cross-sectional study, 112 older adults living in the community were assessed via face-to-face structured interviews. Frailty, cognitive status, medication management and clinical and sociodemographic variables were evaluated. Descriptive and inferential statistics were calculated. The mean participant age was 76.6 ± 7.1 years, 53.6% of participants were women, and 40.2% of participants lived alone. More than half were classified as having frailty (58.9%), almost one-fifth (19.6%) presented with a moderate cognitive impairment had more than one disease, and 60.7% were polymedicated. No associations were found between polymedication and medication self-management, the use of over-the-counter medications, living alone, having a poor understanding of pharmacological therapy and/or pathology, or having more than one prescriber. Self-management was associated with age, the number of medications, frailty and cognitive status. Binary logistic regressions showed that cognitive impairment had statistically significant differences with medication management, having a poor understanding of pharmacological therapy and/or pathology, having one prescriber and the use of medications not prescribed by physicians. Interventions to prevent medication-related problems in home-dwelling older adults are recommended.

RESUMEN

Introduction: This study aims to assess safety and effectiveness of pertuzumab in combination with trastuzumab and docetaxel in the neoadjuvant treatment (NeoT) of HER2-positive breast cancer. Methods: Two consecutive retrospective cohorts (n = 94, 2012-2015 and 2015-2017) of adult women with HER2-positive breast cancer, receiving NeoT at the breast clinic in Portugal (IPO-Porto), were followed. All patients had surgery and received trastuzumab as adjuvant therapy. The 2012-2015 cohort received doxorubicin, cyclophosphamide, docetaxel plus trastuzumab, whereas the 2015-2017 cohort was treated with the same protocol plus pertuzumab. Results: The 2012-2015 cohort was older (median 53 years), with locally advanced tumors (48.1%), mostly hormone receptor positive (59.3%). The 2015-2017 cohort was younger (median 43 years) with 60% operable tumors. Pathologic complete response (pCR) improved in the second cohort, while maintaining a good safety profile and tolerability. Clinical staging (p = 0.001) and hormone receptor (p = 0.003) were significant predictors of pCR, but not treatment regimen (p = 0.304). Conclusion: Further research with larger samples and longer follow-up is needed to understand the clinical differences. Clinical effectiveness of treatment should also be measured through overall and progression-free survival.

RESUMEN

BACKGROUND: Effective medication management is one of the essential preconditions for enabling polymedicated home-dwelling older adults with multiple chronic conditions to remain at home and preserve their quality of life and autonomy. Lack of effective medication management predisposes older adults to medication-related problems (MRPs) and adverse health outcomes, which can lead to the degradation of a patient's acute clinical condition, physical and cognitive decline, exacerbation of chronic medical conditions, and avoidable health care costs. Nonetheless, it has been shown that MRPs can be prevented or reduced by using well-coordinated, patient-centered, interprofessional primary care interventions. OBJECTIVE: This study aimed to explore the feasibility and acceptability of an evidence-based, multicomponent, interprofessional intervention program supported by informal caregivers to decrease MRPs among polymedicated home-dwelling older adults with multiple chronic conditions. METHODS: This quasi-experimental, pre-post, multisite pilot, and feasibility study will use an open-label design, with participants knowing the study's objectives and relevant information, and it will take place in primary health care settings in Portugal and Switzerland. The research population will comprise 30 polymedicated, home-dwelling adults, aged ≥65 years at risk of MRPs and receiving community-based health care, along with their informal caregivers and health care professionals. RESULTS: Before a projected full-scale study, this pilot and feasibility study will focus on recruiting and ensuring the active collaboration of its participants and on the feasibility of expanding this evidence-based, multicomponent, interprofessional intervention program throughout both study regions. This study will also be essential to projected follow-up research programs on informal caregivers' multiple roles, enhancing their coordination tasks and their own needs. Results are expected at the end of 2024. CONCLUSIONS: Designing, establishing, and exploring the feasibility and acceptability of an intervention program to reduce the risks of MRPs among home-dwelling older adults is an underinvestigated issue. Doing so in collaboration with all the different actors involved in that population's medication management and recording the first effects of the intervention will make this pilot and feasibility study's findings very valuable as home care becomes an ever more common solution.

RESUMEN

Urothelial carcinoma on a ureterocele is extremely rare in the literature, and few case reports have been reported. There are no guidelines for diagnosis and management, and current practice is extrapolated from bladder and upper urothelial tract carcinoma. We present a case from a 61-year-old man with urothelial carcinoma on a ureterocele treated with ureterocele resection, distal urethrectomy, and reimplantation on the bladder. We also review the literature concerning diagnostic approaches and management.

RESUMEN

BACKGROUND: Using evidence-based practice (EBP) improves the implementation of safe, high-quality healthcare for patients, reduces avoidable costs, and plays a crucial role in bridging knowledge-action gaps and reducing health inequities. EBP combines the best available evidence in the relevant literature with patient preferences and values and healthcare professionals' (HCPs) expertise. METHODS: Systematic searches of ten bibliographic databases, unpublished works, and the Grey Literature Report sought studies published up to 30 September 2022. RESULTS: The 15 studies retained involved 2712 nurses. Three types of effective educational interventions were identified: (1) multifaceted educational strategies incorporating mentoring and tutoring; (2) single educational strategies, often delivered online; and (3) multifaceted educational strategies using the five steps of EBP. Eleven primary outcomes (EBP beliefs, EBP self-efficacy, perceived EBP implementation, EBP competencies, EBP knowledge, EBP skills, EBP attitudes, EBP behaviors, EBP desire, EBP practice, and perceptions of organizational culture and readiness) were assessed using 13 qualitative and quantitative instruments. CONCLUSIONS: Ensuring the successful implementation of EBP requires effective educational strategies. Computer-based learning seems the most cost-effective and efficient strategy, when considering caregivers' characteristics, the clinical field, and educational interventions across the pre-, peri-, and post-implementation processes.

RESUMEN

Adaptive evolution under controlled laboratory conditions has been highly effective in selecting organisms with beneficial phenotypes such as stress tolerance. The evolution route is particularly attractive when the organisms are either difficult to engineer or the genetic basis of the phenotype is complex. However, many desired traits, like metabolite secretion, have been inaccessible to adaptive selection due to their trade-off with cell growth. Here, we utilize genome-scale metabolic models to design nutrient environments for selecting lineages with enhanced metabolite secretion. To overcome the growth-secretion trade-off, we identify environments wherein growth becomes correlated with a secondary trait termed tacking trait. The latter is selected to be coupled with the desired trait in the application environment where the trait manifestation is required. Thus, adaptive evolution in the model-designed selection environment and subsequent return to the application environment is predicted to enhance the desired trait. We experimentally validate this strategy by evolving Saccharomyces cerevisiae for increased secretion of aroma compounds, and confirm the predicted flux-rerouting using genomic, transcriptomic, and proteomic analyses. Overall, model-designed selection environments open new opportunities for predictive evolution.

RESUMEN

Nurses exhibit higher rates of presenteeism than other professionals, with consequences for the quality of care and patient safety. However, nurses' perceptions of these issues have been poorly explored. This study investigated the perceptions and experiences of frontline nurses and nurse managers in Switzerland and Portugal about the consequences of presenteeism and strategies to minimize it in different healthcare settings. Our qualitative study design used video focus groups involving 55 participants from both countries. Thematic analysis of their transcribed discussions revealed six themes surrounding the consequences of presenteeism: the personal impact on nurses' health and wellbeing, on their family relationships, and on professional frustration and dissatisfaction; the professional impact on work dynamics; the social impact on the quality of care and patient safety and on society's impressions of the profession. At the individual, collective, and institutional levels, six strategies were evoked to minimize presenteeism: encouraging professionals' self-knowledge; creating a positive work atmosphere; facilitating communication channels; developing a positive organizational culture; implementing preventive/curative institutional interventions; identifying and documenting situations linked to presenteeism. Nurses' perceptions and experiences provided a deeper understanding of their presenteeism and revealed underused pathways toward preventing and minimizing presenteeism via bottom-up approaches.

RESUMEN

BACKGROUND: Safe medication management for older adults after hospital discharge requires a well-coordinated, interprofessional, patient-centered approach. This study aimed to describe the perceived needs for collaborative medication management for older adults taking several different medications at home after hospital discharge. METHODS: A qualitative descriptive study was conducted using semi-structured interviews with older adults (n = 28), informal (n = 17), and professional caregivers (n = 13). RESULTS: Findings revealed four main needs: older adults and informal caregivers' perceived needs for greater involvement in discharge planning; older adults' perceived needs to be informed, listened to, and to be actively involved in decision-making; informal caregivers' perceived needs for help in supporting and coordinating medication management; and older adults' and informal and professional caregivers' perceived needs for better communication and coordination between professional caregivers. CONCLUSION: This study revealed two underutilized pathways towards improving collaborative medication management: medication follow-up involving a community healthcare professional taking an overarching responsibility and empowering older adults and their informal caregivers in medication management after hospital discharge.

RESUMEN

Cyber-harassment refers to a pattern of repeated, intentional, and unwanted annoyances, impositions, threats, or other aggravating actions mediated by Information and Communication Technologies. Globally, substantial proportions of adolescents experience cyber-harassment, resulting in a host of deleterious health-related consequences. This study tested the empirical utility of the Lifestyle-Routine Activities Theory in accounting for adolescent cyber-victimization. A representative sample of 627 adolescents, aged 12-16, enrolled in schools from northern Portugal and Azores, were surveyed. Consistent with the theoretical assumptions, older adolescents, who used tablets, published information on social network profiles, added unknown people as friends, met face-to-face with them, and had parents with less knowledge of their online contacts were at increased risk of being cyber-victimized. Theoretical and practical implications are elaborated.
