RESUMO

PURPOSE: The current study sought to evaluate the sexual function of transgender men and women and to identify associated factors. METHODS: Trans individuals who were outpatients at our gender incongruence (GI) center for follow-up of gender-affirming hormone therapy with age ranging 27 to 50 years were invited to participate in this cross-sectional study. Clinical data were collected from the medical records. Two scales, the Female Sexual Function Index (FSFI) and the Male Sexual Function Index (MSFI), were administered to all females (n = 50) and all males (n = 58). Each participant also responded to a semi-structured questionnaire that assessed feelings regarding being transgender and satisfaction with sexual life. RESULTS: Relative to trans women, trans men had a higher total FSFI score, and higher scores in the FSFI domains of arousal, lubrication, orgasm, and satisfaction (all p < 0.01), and in the total MSFI score, and higher scores in the MFSI domains of arousal, erection, orgasm, and satisfaction (all p < 0.01). A separate semi-structured evaluation indicated that more than half of the trans men and almost half of the trans women were satisfied or very satisfied with their sexual life. CONCLUSIONS: The total scores from the FSFI and MSFI indicated a high risk of sexual dysfunction in trans men and especially, in trans women. However, the semi-structured evaluation showed that more than half of the trans men and almost half of the trans women were satisfied with their sexual life.

RESUMO

PURPOSE: We aim to evaluate the impact of surgical wound complications in the first 30 postoperative days after incisional hernia repair on the long-term quality of life of patients. In addition, the impact of the surgical technique and preoperative comorbidities on the quality of life of patients will also be evaluated. METHOD: Prospective cohort study, which evaluates 115 patients who underwent incisional hernioplasty between 2019 and 2020, using the onlay and retromuscular techniques. These patients were initially assessed with regard to surgical wound outcomes in the first 30 postoperative days (surgical site infection (SSI) or surgical site occurrence (SSO)), and then, assessed after three years, through a specific quality of life questionnaire, the Hernia Related Quality of Life Survey (HerQLes). RESULTS: After some patients were lost to follow-up during the study period, due to death, difficulty in contact, refusal to respond to the questionnaire, eighty patients were evaluated. Of these, 11 patients (13.8%) had SSI in the first 30 postoperative days and 37 (46.3%) had some type of SSO. The impact of both SSI and SSO on quality of life indices was not identified. When analyzing others variables, we observed that the Body Mass Index (BMI) had a significant impact on the patients' quality of life. Likewise, hernia size and mesh size were identified as variables related to a worse quality of life outcome. No difference was observed regarding the surgical techniques used. CONCLUSION: In the present study, no relationship was identified between surgical wound outcomes (SSO and SSI) and worse quality of life results using the HerQLes score. We observed that both BMI and the size of meshes and hernias showed an inversely proportional relationship with quality of life indices. However, more studies evaluating preoperative quality of life indices and comparing them with postoperative indices should be carried out to evaluate these correlations.

RESUMO

AIM: In cyclic climate variations, including seasonal changes, many animals regulate their energy demands to overcome critical transitory moments, restricting their high-demand activities to phases of resource abundance, enabling rapid growth and reproduction. Tegu lizards (Salvator merianae) are ectotherms with a robust annual cycle, being active during summer, hibernating during winter, and presenting a remarkable endothermy during reproduction in spring. Here, we evaluated whether changes in mitochondrial respiratory physiology in skeletal muscle could serve as a mechanism for the increased thermogenesis observed during the tegu's reproductive endothermy. METHODS: We performed high-resolution respirometry and calorimetry in permeabilized red and white muscle fibers, sampled during summer (activity) and spring (high activity and reproduction), in association with citrate synthase measurements. RESULTS: During spring, the muscle fibers exhibited increased oxidative phosphorylation. They also enhanced uncoupled respiration and heat production via adenine nucleotide translocase (ANT), but not via uncoupling proteins (UCP). Citrate synthase activity was higher during the spring, suggesting greater mitochondrial density compared to the summer. These findings were consistent across both sexes and muscle types (red and white). CONCLUSION: The current results highlight potential cellular thermogenic mechanisms in an ectothermic reptile that contribute to transient endothermy. Our study indicates that the unique feature of transitioning to endothermy through nonshivering thermogenesis during the reproductive phase may be facilitated by higher mitochondrial density, function, and uncoupling within the skeletal muscle. This knowledge contributes significant elements to the broader picture of models for the evolution of endothermy, particularly in relation to the enhancement of aerobic capacity.

RESUMO

BACKGROUND: Work-related musculoskeletal disorders for upper limbs (UL-WMSDs) form a complex of occupational diseases common to many professions worldwide. UL-WMSDs are manifested in most cases by pain, resulting in musculoskeletal discomfort. OBJECTIVE: This research aimed to evaluate the perception of musculoskeletal discomfort in workers from the interior of the Brazilian states of Alagoas and Bahia through the construction of a scale to assess musculoskeletal discomfort for upper limb. METHODS: The discomfort assessment scale was constructed from self-reported pain symptoms by 420 workers from the inner regions of the Brazilian states of Alagoas and Bahia. The reliability and dimensionality of the collected data were analyzed by McDonald's Omega and exploratory factor analysis, respectively. Item Response Theory (IRT) was used to create parameters for the discomfort scale. RESULTS: The musculoskeletal discomfort metric was constructed from the workers' response with six levels (varying from minimum discomfort to maximum discomfort). At the lowest level of the scale, workers indicated symptoms in the shoulders and wrists were rare. At the highest level of the scale, daily pain symptoms are reported in all regions of the upper limbs. The shoulders are the last region to develop extreme pain symptoms. CONCLUSION: The metric was created to present satisfactory psychometric properties and capable measurement of the workers' level of musculoskeletal discomfort based on self-reported pain symptoms. Therefore, the metric can support measuring discomfort, contributing to decisions that improve a healthier occupational environment for the worker.

RESUMO

Neuronal activity requires a large amount of ATP, leading to a rapid collapse of brain function when aerobic respiration fails. Here, we summarize how rhythmic motor circuits in the brain stem of adult frogs, which normally have high metabolic demands, transform to produce proper output during severe hypoxia associated with emergence from hibernation. We suggest that general principles underlying plasticity in brain bioenergetics may be uncovered by studying nonmammalian models that face extreme environments, yielding new insights to combat neurological disorders involving dysfunctional energy metabolism.

RESUMO

Brain energy stress leads to neuronal hyperexcitability followed by a rapid loss of function and cell death. In contrast, the frog brainstem switches into a state of extreme metabolic resilience that allows them to maintain motor function during hypoxia as they emerge from hibernation. NMDA receptors (NMDARs) are Ca2+-permeable glutamate receptors that contribute to the loss of homeostasis during hypoxia. Therefore, we hypothesized that hibernation leads to plasticity that reduces the role of NMDARs within neural networks to improve function during hypoxia. To test this, we assessed a circuit with a large involvement of NMDAR synapses, the brainstem respiratory network of female bullfrogs, Lithobates catesbeianus Contrary to our expectations, hibernation did not alter the role of NMDARs in generating network output, nor did it affect the amplitude, kinetics, and hypoxia sensitivity of NMDAR currents. Instead, hibernation strongly reduced NMDAR Ca2+ permeability and enhanced desensitization during repetitive stimulation. Under severe hypoxia, the normal NMDAR profile caused network hyperexcitability within minutes, which was mitigated by blocking NMDARs. After hibernation, the modified complement of NMDARs protected against hyperexcitability, as disordered output did not occur for at least one hour in hypoxia. These findings uncover state-dependence in the plasticity of NMDARs, whereby multiple changes to receptor function improve neural performance during metabolic stress without interfering with their normal role during healthy conditions.

RESUMO

Abdominal obesity, regardless of overall obesity, is associated with metabolic abnormalities and with direct impact on cardiovascular risk. The aim of this study was to compare body mass index (BMI), waist circumference (WC), and waist-to-height ratio (WHtR) to estimate cardiovascular disease (CVD) prevalence in individuals with chronic kidney disease (CKD). The data analyzed is from 2005-2016 cycles of the NHANES. A total of 2,825 participants with CKD were included in this study, and most of them had a high BMI, 66.1%, to be exact (BMI ≥ 25.0 kg/m² if age <65 or >27.0 if age ≥ 65). The prevalence rates of high WC (≥102 cm for men or ≥88 cm for women) and high WHtR (WHtR>0.5) in the study population were 70.0% and 91.0%, respectively. The results of this study suggest that BMI is a good indicator of the risk of CVDs in individuals with CKD. In addition, the results show that WC and WHtR are associated with CVDs in non-overweight individuals of both sexes. These results indicate that the assessment of abdominal fat is essential even in non-overweight patients because the risk of CVDs cannot be identified in this subpopulation using only BMI.

RESUMO

OBJECTIVE: This study aimed to evaluate the role of pepsin inhibitors in the inflammatory response and their effects on laryngeal mucosal integrity during gastroesophageal reflux (GERD) under in vivo conditions. METHODS: A surgical model of GERD was used, in which mice were treated with pepstatin (0.3 mg/kg) or darunavir (8.6 mg/kg) for 3 days. On the third day after the experimental protocol, the laryngeal samples were collected to assess the severity of inflammation (wet weight and myeloperoxidase activity) and mucosal integrity (transepithelial electrical resistance and paracellular epithelial permeability to fluorescein). RESULTS: The surgical GERD model was reproduced. It showed features of inflammation and loss of barrier function in the laryngeal mucosa. Pepstatin and darunavir administration suppressed laryngeal inflammation and preserved laryngeal mucosal integrity. CONCLUSION: Pepsin inhibition by the administration of pepstatin and darunavir improved inflammation and protected the laryngeal mucosa in a mouse experimental model of GERD. LEVEL OF EVIDENCE: NA Laryngoscope, 134:3080-3085, 2024.

RESUMO

TDP-43-positive inclusions in neurons are a hallmark of several neurodegenerative diseases including familial amyotrophic lateral sclerosis (fALS) caused by pathogenic TARDBP variants as well as more common non-Mendelian sporadic ALS (sALS). Here we report a G376V-TDP-43 missense variant in the C-terminal prion-like domain of the protein in two French families affected by an autosomal dominant myopathy but not fulfilling diagnostic criteria for ALS. Patients from both families presented with progressive weakness and atrophy of distal muscles, starting in their 5th-7th decade. Muscle biopsies revealed a degenerative myopathy characterized by accumulation of rimmed (autophagic) vacuoles, disruption of sarcomere integrity and severe myofibrillar disorganization. The G376 V variant altered a highly conserved amino acid residue and was absent in databases on human genome variation. Variant pathogenicity was supported by in silico analyses and functional studies. The G376 V mutant increased the formation of cytoplasmic TDP-43 condensates in cell culture models, promoted assembly into high molecular weight oligomers and aggregates in vitro, and altered morphology of TDP-43 condensates arising from phase separation. Moreover, the variant led to the formation of cytoplasmic TDP-43 condensates in patient-derived myoblasts and induced abnormal mRNA splicing in patient muscle tissue. The identification of individuals with TDP-43-related myopathy but not ALS implies that TARDBP missense variants may have more pleiotropic effects than previously anticipated and support a primary role for TDP-43 in skeletal muscle pathophysiology. We propose to include TARDBP screening in the genetic work-up of patients with late-onset distal myopathy. Further research is warranted to examine the precise pathogenic mechanisms of TARDBP variants causing either a neurodegenerative or myopathic phenotype.

RESUMO

BACKGROUND: Adhesive small bowel obstruction is one of the most common causes of surgical emergencies, representing about 15% of hospital admissions. Defining the need and timing of surgical intervention still remains a challenge. AIMS: To report the experience of using meglumine-based water-soluble contrast in a tertiary hospital in southern Brazil, comparing with the world literature. METHODS: Patients suspected of having adhesive small bowel obstruction, according to their clinical conditions, underwent an established protocol, consisting of the administration of water-soluble contrast, followed by plain abdominal radiograph within 12 hours and by a new clinical evaluation. The protocol was initiated after starting conservative management, including fasting and placement of a nasogastric tube, as well as intravenous fluid reposition. RESULTS: A total of 126 patients were submitted to the protocol. The water-soluble contrast test sensitivity and specificity after the first radiograph were 94.6 and 91.0%, respectively; after the second radiograph, these values were 92.3 and 100%. The general test values for sensitivity and specificity were 91.9 and 100%, respectively. CONCLUSIONS: The measure parameters evaluated in this study were similar to those found in the literature, contributing to endorse the importance of this test in the evaluation of patients with adhesive small bowel obstruction. The particular relevance of this study was the similar results that were found using a different type of meglumine-based contrast, which is available in Brazil.

RESUMO

Cytoplasmic aggregation and concomitant nuclear clearance of the RNA-binding protein TDP-43 are found in ~ 90% of cases of amyotrophic lateral sclerosis and ~ 45% of patients living with frontotemporal lobar degeneration, but no disease-modifying therapy is available. Antibody therapy targeting other aggregating proteins associated with neurodegenerative disorders has shown beneficial effects in animal models and clinical trials. The most effective epitopes for safe antibody therapy targeting TDP-43 are unknown. Here, we identified safe and effective epitopes in TDP-43 for active and potential future passive immunotherapy. We prescreened 15 peptide antigens covering all regions of TDP-43 to identify the most immunogenic epitopes and to raise novel monoclonal antibodies in wild-type mice. Most peptides induced a considerable antibody response and no antigen triggered obvious side effects. Thus, we immunized mice with rapidly progressing TDP-43 proteinopathy ("rNLS8" model) with the nine most immunogenic peptides in five pools prior to TDP-43ΔNLS transgene induction. Strikingly, combined administration of two N-terminal peptides induced genetic background-specific sudden lethality in several mice and was therefore discontinued. Despite a strong antibody response, no TDP-43 peptide prevented the rapid body weight loss or reduced phospho-TDP-43 levels as well as the profound astrogliosis and microgliosis in rNLS8 mice. However, immunization with a C-terminal peptide containing the disease-associated phospho-serines 409/410 significantly lowered serum neurofilament light chain levels, indicative of reduced neuroaxonal damage. Transcriptomic profiling showed a pronounced neuroinflammatory signature (IL-1ß, TNF-α, NfκB) in rNLS8 mice and suggested modest benefits of immunization targeting the glycine-rich region. Several novel monoclonal antibodies targeting the glycine-rich domain potently reduced phase separation and aggregation of TDP-43 in vitro and prevented cellular uptake of preformed aggregates. Our unbiased screen suggests that targeting the RRM2 domain and the C-terminal region of TDP-43 by active or passive immunization may be beneficial in TDP-43 proteinopathies by inhibiting cardinal processes of disease progression.

RESUMO

A pitiríase versicolor (PV) consiste em uma infecção fúngica ocasionada por leveduras de Malassezia spp., que apesar de manejo simples, é uma doença com elevadas chances de recidiva e cronificação, além da pouca variedade de terapias efetivas para tratar cepas resistentes. Existem relatos na literatura sobre utilização de dessensibilização para Malassezia spp., mas para o tratamento de dermatite atópica e não PV, conferindo caráter inovador ao relato em questão. O caso apresentado consiste em um paciente de 28 anos, do sexo masculino, com manifestações típicas de PV em região de face, cervical, dorsal e axilar, há 4 anos, com resistência aos esquemas terapêuticos tópicos e sistêmicos. Uma vez identificada a ineficácia das terapias tradicionais, foi iniciado o tratamento com dessensiblização para Malassezia spp., em aplicações semanais, com aumento progressivo da dosagem e posterior aumento no intervalo das aplicações. Após onze meses de realização do novo tratamento, o paciente evoluiu com melhora completa das lesões. Conclui-se que a utilização de técnicas imunoterápicas para o tratamento de PV foi considerado eficaz no caso relatado, apesar de ainda não haver evidências que amparem sua utilização em maior escala.


Pityriasis versicolor is a infection caused by Malassezia yeast species, which, despite simple management, involves a high risk of recurrence and chronicity, and there are few effective therapies for resistant strains. Desensitization for Malassezia spp. has been reported in the literature, but for atopic dermatitis, rather than pityriasis versicolor, making this an innovative report. The case presented herein is of a 28-year-old man who had typical manifestations of pityriasis versicolor in the face, cervical, dorsal, and axillary region for 4 years that were resistant to topical and systemic therapies. Once the ineffectiveness of traditional therapies had been determined, weekly Malassezia desensitization sessions were begun, progressively increasing first in dosage and then in frequency. After 11 months, the lesions had improved completely. In this case, immunotherapeutic techniques effectively treated pityriasis versicolor, although the evidence is as yet insufficient to support large-scale use.

RESUMO

OBJECTIVE: To build and validate a self-report instrument to assess the comfort of adolescents with cancer undergoing chemotherapy. METHODS: This methodological study was developed in five stages: scoping review; qualitative study to characterize comfort from the perspective of adolescents with cancer undergoing chemotherapy; instrument construction; instrument content validation by experts; pre-test with a group of adolescents. RESULTS: In the scoping review, 20 comfort changes were identified; regarding the perspective of comfort for adolescents, it was possible to identify the effects on their daily lives and the impact on chemotherapy; in content validation, the index was 0.96 and Cronbach's Alpha 0.87. In the pre-test, the instrument obtained the final version with 37 items and Cronbach's Alpha 0.94. CONCLUSIONS: The constructed and validated self-report instrument showed good reliability related to satisfactory psychometric parameters and can be used by nurses in clinical practice to assess and evidence comfort changes.

RESUMO

Locus coeruleus (LC) neurons regulate breathing by sensing CO2/pH. Neurons within the vertebrate LC are the main source of norepinephrine within the brain. However, they also use glutamate and GABA for fast neurotransmission. Although the amphibian LC is recognized as a site involved in central chemoreception for the control of breathing, the neurotransmitter phenotype of these neurons is unknown. To address this question, we combined electrophysiology and single-cell quantitative PCR to detect mRNA transcripts that define norepinephrinergic, glutamatergic, and GABAergic phenotypes in LC neurons activated by hypercapnic acidosis (HA) in American bullfrogs. Most LC neurons activated by HA had overlapping expression of noradrenergic and glutamatergic markers but did not show strong support for GABAergic transmission. Genes that encode the pH-sensitive K+ channel, TASK2, and acid-sensing cation channel, ASIC2, were most abundant, while Kir5.1 was present in 1/3 of LC neurons. The abundance of transcripts related to norepinephrine biosynthesis linearly correlated with those involved in pH sensing. These results suggest that noradrenergic neurons in the amphibian LC also use glutamate as a neurotransmitter and that CO2/pH sensitivity may be linkedto the noradrenergic cell identity.

RESUMO

BACKGROUND: Neural circuit function is highly sensitive to energetic limitations. Much like mammals, brain activity in American bullfrogs quickly fails in hypoxia. However, after emergence from overwintering, circuits transform to function for approximately 30-fold longer without oxygen using only anaerobic glycolysis for fuel, a unique trait among vertebrates considering the high cost of network activity. Here, we assessed neuronal functions that normally limit network output and identified components that undergo energetic plasticity to increase robustness in hypoxia. RESULTS: In control animals, oxygen deprivation depressed excitatory synaptic drive within native circuits, which decreased postsynaptic firing to cause network failure within minutes. Assessments of evoked and spontaneous synaptic transmission showed that hypoxia impairs synaptic communication at pre- and postsynaptic loci. However, control neurons maintained membrane potentials and a capacity for firing during hypoxia, indicating that those processes do not limit network activity. After overwintering, synaptic transmission persisted in hypoxia to sustain motor function for at least 2 h. CONCLUSIONS: Alterations that allow anaerobic metabolism to fuel synapses are critical for transforming a circuit to function without oxygen. Data from many vertebrate species indicate that anaerobic glycolysis cannot fuel active synapses due to the low ATP yield of this pathway. Thus, our results point to a unique strategy whereby synapses switch from oxidative to exclusively anaerobic glycolytic metabolism to preserve circuit function during prolonged energy limitations.

RESUMO

Estudos recentes evidenciam que a ansiedade é conceituada como o mal do século. De acordo com a Organização Mundial da Saúde (OMS), 18,6 milhões de brasileiros sofrem com algum distúrbio relacionado à ansiedade. A fisiopatologia da doença tem relação com a disfunção de neurotransmissores, tornando extremamente necessário o estudo dos neurotransmissores que auxiliam no combate ao transtorno da ansiedade. Realizou-se uma revisão bibliográfica sistemática observacional retrospectiva baseada em artigos científicos coletados nas bases de dados Scielo, Google Acadêmico e Biblioteca Virtual em Saúde (BVS). Uma alimentação balanceada e rica em micronutrientes fornece aos neurônios os nutrientes essenciais para a produção dos neurotransmissores responsáveis pela transmissão de mensagens cognitivas, incluindo sentimentos, emoções e pensamentos do indivíduo, podendo auxiliar significativamente na melhora do quadro de ansiedade. Os estudos levantados associam a correta ingestão de nutrientes como triptofano, vitamina D e ômega-3 como eficaz auxílio no tratamento da ansiedade. O objetivo do presente estudo é descrever a relação e eficácia do fator alimentação no tratamento do transtorno da ansiedade.
