RESUMO

PURPOSE: Currently, inguinal hernias are highly prevalent in the Brazilian population, accounting for 75% of all abdominal wall hernias. The recommended treatment to correct them is inguinal herniorrhaphy, which can be performed through open surgery, mainly using the Lichtenstein technique, or laparoscopically, primarily through Transabdominal Preperitoneal Repair (TAPP) or Total Extraperitoneal Repair (TEP) approaches. Like any surgery, these procedures have post-operative complications, with pain being the most common and debilitating. Currently, in European and Brazilian guidelines, the open Lichtenstein and endoscopic inguinal hernia techniques are recommended as best evidence-based options for repair of a primary unilateral hernia providing the surgeon is sufficiently experienced in the specific procedure. In that matter, the surgeon should make a choice based on assessment of the benefits and risks of performing each of them, and practice shared making decision with it patient. Therefore, the objective of this review was to assess the incidence of chronic postoperative pain by comparing the aforementioned surgical approaches to evaluate which procedure causes less disability to the patient. METHODS: The search conducted until May 2024 was performed on Medline (PubMed), Cochrane (CENTRAL), and Lilacs databases. The selection was limited to randomized clinical trials, nonrandomized clinical trials and cohort studies comparing TAPP or TEP to LC, evaluating the incidence of chronic postoperative pain published between 2017 and 2023. Evidence certainty was assessed using the GRADE Pro tool, and bias risk was evaluated with the RoB 2.0 tool and ROBINS I tool. Thirteen studies were included.  RESULTS: The meta-analysis showed a significant difference between the groups in both techniques, favoring the laparoscopic approach, which had a lower occurrence of postoperative inguinodynia with a relative risk of 0.49 (95% CI = 0.32, 0.75; I2 = 66% (P = 0.001); Z = 3.28 (P = 0.001) with low certainty of evidence. CONCLUSION: The presence of chronic postoperative pain was lower in laparoscopic TEP/TAPP techniques when compared to the open Lichtenstein technique, meaning that the former can bring more benefits to patients who requires inguinal herniorrhaphy. Nevertheless, further randomized clinical trials are needed to optimize the analysis, minimizing the bias.

RESUMO

Ovarian cancer (OC) adjusts energy metabolism in favor of its progression and dissemination. Because melatonin (Mel) has antitumor actions, we investigated its impact on energy metabolism and kinase signaling in OC cells (SKOV-3 and CAISMOV-24). Cells were divided into control and Mel-treated groups, in the presence or absence of the antagonist luzindole. There was a decrease in the levels of HIF-1α, G6PDH, GAPDH, PDH, and CS after Mel treatment even in the presence of luzindole in both OC cells. Mel treatment also reduced the activity of OC-related enzymes including PFK-1, G6PDH, LDH, CS, and GS whereas PDH activity was increased. Lactate and glutamine levels dropped after Mel treatment. Mel further promoted a reduction in the concentrations of CREB, JNK, NF-kB, p-38, ERK1/2, AKT, P70S6K, and STAT in both cell lines. Mel reverses Warburg-type metabolism and possibly reduces glutaminolysis, thereby attenuating various oncogenic molecules associated with OC progression and invasion.

RESUMO

INTRODUCTION: Hospitalization often causes mobility difficulties and hinders daily activities. Progressive mobilization of patients in intensive care units (ICUs) is safe and linked to better clinical and functional outcomes. OBJECTIVE: To assess the perception of a multidisciplinary team in the ICUs of a university hospital regarding early mobilization (EM). METHODS: A prospective observational study was conducted using data collected from professionals and students in the ICU of Clementino Fraga Filho University Hospital at the Federal University of Rio de Janeiro between June and December 2019. Data on EM perception were collected using a questionnaire. Descriptive statistics and Fisher's exact tests were used to analyze the differences between the professional categories. RESULTS: In comparison to physiotherapists (88%), a smaller percentage of physicians (37.5%) and nurses (50%) reported that patients on mechanical ventilation (MV) are mobilized within 48 hours (P80%), with the main perceived barriers being the availability of professionals (58%), the clinical condition of patients (55%), and patients undergoing procedures (45%). CONCLUSION: In a university hospital without an established EM protocol, the multidisciplinary team showed satisfactory knowledge and perceptions of EM. However, creating institutional protocols and guidelines is essential to engage multidisciplinary teams in implementing EM and overcoming barriers.

INTRODUÇÃO: A hospitalização frequentemente causa dificuldades de mobilidade e compromete as atividades da vida diária. A mobilização progressiva de pacientes em unidades de terapia intensiva (UTI) é segura e está associada a melhores resultados clínicos e funcionais. OBJETIVO: Avaliar a percepção da equipe multiprofissional das UTIs de um hospital universitário quanto à mobilização precoce (MP). MÉTODOS: Foi realizado um estudo prospectivo e observacional com dados coletados de profissionais e estudantes da UTI do Hospital Universitário Clementino Fraga Filho da Universidade Federal do Rio de Janeiro entre junho e dezembro de 2019. Os dados sobre a percepção da MP foram coletados por meio de questionário. A estatística descritiva e o teste exato de Fisher foram utilizados para analisar as diferenças entre categorias profissionais. RESULTADOS: Em comparação aos fisioterapeutas (88%), um percentual menor de médicos (37,5%) e enfermeiros (50%) relataram que os pacientes em ventilação mecânica (VM) são mobilizados em 48 horas (P80%), sendo as principais barreiras percebidas a indisponibilidade de profissionais (58%), a condição clínica (55%) e pacientes submetidos a procedimentos (45%). CONCLUSÃO: Em um hospital universitário sem protocolo de MP estabelecido, a equipe multidisciplinar apresenta percepção satisfatória sobre a MP. Contudo, a criação de protocolos e diretrizes institucionais é essencial para engajar a equipe na implementação da MP e na superação de barreiras.

RESUMO

This study assessed the cardiovascular repercussions of two VHI (ventilation hyperinflation) protocols using the volume-controlled mode, one with an inspiratory pause (VHI-P) and the other without an inspiratory pause (VHI-NP), in mechanically ventilated elderly patients. The patients underwent both VHI protocols in a randomized order, and impedance cardiography was used to record cardiovascular variables. During VHI-P, the diastolic blood pressure was lower than during VHI-NP (Δ = 10%; p = 0.009). VHI-NP and VHI-P demonstrated a decrease in cardiac output (CO) during the first and third sets compared to baseline (p < 0.05; ES=0.23 and 0.29, respectively). Arterial oxygen delivery decreased simultaneously with CO compared to baseline values (p < 0.05; ES=0.22 and 0.23, respectively). Five minutes after the intervention, the systolic time ratio values were lower for VHI-P than VHI-NP (Δ = 10%; p = 0.01). Left ventricular ejection time values were consistently lower in VHI-NP compared to VHI-P (Δ = 2%; p = 0.02). In conclusion, our study shows that VHI in volume-controlled mode induces hemodynamic changes in mechanically ventilated elderly patients, albeit with a small effect size and within the normal range.

RESUMO

BACKGROUND: Chest physiotherapy for hospitalized patients with COVID-19 has been poorly reported. Although recommendations were published to guide physiotherapists, practice might have differed depending on education and training. OBJECTIVE: To analyze the differences in chest physiotherapy applied for hospitalized patients with COVID-19 between certified specialists and non-certified specialists. METHODS: An online questionnaire survey was developed for physiotherapists involved in the management of hospitalized patients with COVID-19. The questionnaire inquired about professional information and characteristics of physiotherapy practice. RESULTS: There were 485 respondents, yielding a completion rate of 76%. Of these, 61 were certified specialists and 424 non-certified specialists. The certified specialists were older, had more years of professional experience, were more qualified, and had better job conditions. For mechanically ventilated patients, the certified specialists used the ventilator hyperinflation maneuver more frequently (50.4% vs 35.1%, p = 0.005), and the hard/brief expiratory rib cage compression (ERCC) (26.9% vs 48.3%, p = 0.016), soft/long ERCC (25.2% vs 39.1%, p = 0.047), and manual chest compression-decompression (MCCD) maneuver (22.4% vs 35.6%, p = 0.001) less often. For spontaneously breathing patients, the certified specialists used the active cycle of breathing technique (30.8% vs 67.1%, p<0.001), autogenic drainage (7.7% vs 20.7%, p = 0.017), and MCCD maneuver (23.1% vs 41.4%, p = 0.018) less frequently. CONCLUSIONS: Certified specialists with higher levels of expertise seem to prefer the use of chest physiotherapy techniques that are applied with the mechanical ventilator over manual techniques. Furthermore, they use techniques that could potentially increase the work of breathing less frequently, mitigating the risk of exacerbating respiratory conditions in patients with COVID-19.

RESUMO

Killer cell immunoglobulin-like receptors (KIR) exhibit extensive diversity, giving rise to different KIR profiles in populations worldwide. This study aimed to investigate the distribution of KIR genes and HLA ligands in a population from Campinas, southeastern Brazil (n = 292), and to compare their results with other populations. A comprehensive analysis of population-specific genes, genotype, and haplotype frequencies of KIR may facilitate a better understanding of their evolution and role in immunity. The genotyping of 16 KIR genes and HLA class I alleles was performed by the reverse sequence-specific oligonucleotide methodology using the Luminex platform (One Lambda, Inc., Canoga Park, CA). The framework genes were present in all individuals, with the most common non-framework KIR genes detected being KIR2DP1(96.6%), KIR2DL1(95.5%), KIR3DL1(94.5%), KIR2DS4(93.8%) and KIR2DL3(87.3%). KIR2DS1, KIR2DS3, KIR2DS5, and KIR3DS1 presented frequencies below 40%. KIR2DL2, KIR2DL5, and KIR2DS2 showed intermediate frequencies (between53% and 58%). The activating gene KIR2DS5 was the least common in this population (30.8%). Forty-five KIR profiles were found with the commonest being the homozygous A haplotype (27.4%). The distribution of KIR genes in the Brazilian population is similar to Caucasian European and Euro-descendant populations.

RESUMO

BACKGROUND: The Post-COVID-19 Functional Status (PCFS) scale was created to assess the functional status of patients after hospital discharge due to COVID-19. OBJECTIVE: To perform cross-cultural adaptation of the PCFS Scale and Manual into Brazilian Portuguese and evaluate its measurement properties in patients post-COVID-19. METHODS: For the cross-cultural adaptation, independent translations and back-translations were performed. This was followed by a pre-test, with analysis of the Content Validity Index (CVI), and preparation of the final version, after evaluating the measurement properties. Spearman's correlation between the PCFS and the WHO Disability Classification Scheme (WHODAS 2.0) was used for convergent validity. Weighted Kappa (wκ) was used for test-retest and interobserver reliability for PCFS scores and Kappa (κ) for PCFS items. Internal consistency was assessed using Cronbach's alpha. Only patients with post-discharge COVID-19 were evaluated through video-conferencing platforms. RESULTS: The CVI was 0.75-0.83 for comprehension and 0.83-0.84 for the language of the self-administered questionnaire and the structured interview version. For measurement properties, 63 patients were evaluated, 68% male, 51.50 (12.60) years, 12.28 (7.62) days of hospitalization. For the convergent validity, a strong correlation was found (r = 0.73; p<0.01). The test-retest (wκ=0.54) and interobserver (wκ=0.43) reliability was moderate and the item-by-item analyzes ranged from fair to substantial (κ=0.25-0.66) and weak to substantial (κ=0.07-0.79). Internal consistency was excellent (0.85). CONCLUSION: The final PCFS in Brazilian Portuguese showed adequate content validity, reliability, internal consistency, and convergent validity for the functional assessment of patients after hospital discharge due to COVID-19.

RESUMO

BACKGROUND AND PURPOSE: Despite intense efforts, predicting hospital readmission risks remains an imprecise task. Growing evidence suggests that unmeasured patient-related factors, such as functional impairment, seem to be strongly associated with acute readmission and have yet to be extensively explored. We hypothesized that gait speed, hand grip strength, and the Functional independence measure (FIM) might be associated with acute rehospitalization rates after an ICU stay. METHODS: In our study, we assessed gait speed using a 10-m walk test. Muscle strength was determined by a hydraulic handgrip dynamometer and functional status through the FIM. Our primary outcome was the cumulative incidence of the first unplanned early rehospitalization (occurring within 30 days of hospital discharge) for the entire cohort, and a Receiver Operator Characteristic (ROC) analysis was used to determine the accuracy of gait speed, handgrip strength, and FIM domains in predicting hospital readmission. RESULTS: ROC analysis indicated that the gait speed (AUC 0.96 95% CI 0.93 to 0.99), FIM score (AUC 0.96 95% CI 0.94 to 0.99) and handgrip strength (0.85 95% CI 0.76 to 0.94) were considered accurate predictors of unplanned readmission in the population studied. Additionally, we found that each 0.1 m/s lower gait speed was associated with a 10% higher odd of unplanned readmissions. CONCLUSION: Hence, our results suggest gait speed, handgrip strength and functional status demonstrated high potential to contribute to the determination of 30-day unplanned hospital readmission prediction of critical care survivors.

RESUMO

BACKGROUND: Silicone implants have been used to improve volume and body contour in buttocks for almost 45 years. Although the intramuscular plane continues to be the standard, surgeons still diverge on the best incision technique: using a vertical incision, and thus without the preservation of the intergluteal groove, or preserving this area through a triangular dissection. The goal of this research study was to evaluate and compare these techniques of intramuscular augmentation gluteoplasty. METHODS: Two randomized groups were formed with 53 patients in each group. One of the groups underwent intramuscular gluteoplasty with a vertical incision in the intergluteal groove, and therefore without the preservation of said intergluteal groove (group A). In the other group, intramuscular gluteoplasty was performed using a triangular dissection, thus preserving the intergluteal groove (group B). The groups were compared in relation to the incidence of complications (ie, dehiscence, hematoma, seroma, and infection). RESULTS: A total of 7.5% of patients in group A presented dehiscence and 1.9% presented seroma. In group B, however, 28.3% of patients presented dehiscence and 7.5% presented seroma and dehiscence during the first 21 days after surgery. No patient had hematoma or infection in either group. CONCLUSION: In the comparison between the groups of patients, the technique with a vertical incision in the intergluteal groove showed a lower number of surgical wounds, dehiscences, and seromas when compared with the technique that preserves the intergluteal groove. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, II.
