Hyperangulated versus Macintosh blades for intubation with videolaryngoscopy in ICU: the randomised multicentre INVIBLADE-ICU trial study protocol.

INTRODUCTION: Compared with the operating room, tracheal intubations in the intensive care unit (ICU) are associated with worsened glottic view, decreased first-time success rate and increase in the technical difficulty of intubation and incidence of complications. Videolaryngoscopes (VLs) have been proposed to improve airway management, and while recent studies have confirmed that VLs improve intubation conditions in this patient population, there remains a lack of clarity regarding the selection between a standard Macintosh blade or a hyperangulated one, to determine which yields the best outcomes. The purpose of this study was to compare successful intubation on the first attempt with the Macintosh VL versus the hyperangulated VL during tracheal intubation in ICU patients. We hypothesise that tracheal intubation using the hyperangulated VL will improve the frequency of successful intubation on the first attempt. METHODS AND ANALYSIS: The INtubation VIdeolaryngoscopy BLADE-ICU trial is a prospective, multicentre, open-label, interventional, randomised, controlled superiority study conducted in 29 ICUs in Spain. Patients will be randomly assigned in a 1:1 ratio to undergo intubation using a Macintosh VL (control group) or a hyperangulated VL (experimental group) for the first intubation attempt. The primary outcome is successful intubation on the first attempt. The secondary outcomes include the time to intubation, attempts for successful intubation, laryngoscopic vision assessed with the modified Cormack-Lehane scale, the need for adjuvant airway devices for intubation, difficulty assessed by the anaesthesiologist and complications during tracheal intubation. Enrolment began on 1 May 2024 and is expected to be completed in 2025. ETHICS AND DISSEMINATION: The study protocol was approved on 29 February 2024, by the Ethics Committee of Galicia (CEImG, code No. 2024-031).The results will be submitted for publication in a peer-reviewed journal. TRIAL REGISTRATION NUMBER: NCT06322719.

"The effects of non-surgical periodontal treatment plus zinc and magnesium supplementation on oxidative stress and antioxidants enzymes in type 2 diabetes patients: a quasi-experimental study".

BACKGROUND: Periodontal Disease (PD) associated with Type 2 Diabetes Mellitus (T2DM) is a chronic condition that affects the oral cavity of people living with T2DM. The mechanisms of the interaction between type 2 Diabetes Mellitus and Periodontal diseases are complex and involve multiple pathophysiological pathways related to the systemic inflammatory process and oxidative stress. Non-surgical periodontal treatment (NSTP) is considered the standard for the management of this disease; however, patients with systemic conditions such as type 2 Diabetes Mellitus do not seem to respond adequately. For this reason, the use of complementary treatments has been suggested to support non-surgical periodontal treatment to reduce the clinical consequences of the disease and improve the systemic conditions of the patient. The use of zinc gluconate and magnesium oxide as an adjunct to non-surgical periodontal treatment and its effects on periodontal clinical features and oxidative stress in patients with Periodontal diseases -type 2 Diabetes Mellitus is poorly understood. METHODS: A quasi-experimental study was performed in patients with periodontal diseases associated with T2DM. Initially, 45 subjects who met the selection criteria were included. 19 were assigned to a control group [non-surgical periodontal treatment] and 20 to the experimental group (non-surgical periodontal treatment + 500 mg of magnesium oxide and 50 mg of zinc gluconate for oral supplementation for 30 days) and the data of 6 patients were eliminated. Sociodemographic characteristics, physiological factors, biochemical parameters, and clinical features of periodontal diseases were assessed. RESULTS: In this research a change in periodontal clinical characteristics was observed, which has been associated with disease remission. Additionally, a shift in MDA levels was presented for both groups. Furthermore, the supplementation group showed an increase in antioxidant enzymes when compared to the group that only received NSPT. CONCLUSION: The use of Zinc gluconate and magnesium oxide can serve as a complementary treatment to non-surgical periodontal treatment, that supports the remission of PD as a result of regulation-reduction of oxidative biomarkers and increase in antioxidant enzymes activity.

Sentinel Lymph Node Biopsy After Neoadjuvant Chemotherapy in cN0 Breast Cancer: Impact of HER2-Positive Status on Survival.

Objective: High rates of negative sentinel lymph node biopsy (SLNB) in clinically node-negative (cN0) breast cancer (BC) after neoadjuvant chemotherapy (NAC) have been described. These results are associated with triple-negative (TNBC) and human epidermal growth factor receptor 2 (HER2+) subtypes achieving pathologic complete response (pCR). This study evaluates predictive variables and survival in order to assess the possible omission of SLNB after NAC. Materials and Methods: Prospective study of women with cN0 BC treated with NAC and subsequent surgery, between April 2010 and May 2021. SLNB technique included, performing axillary lymphadenectomy in the absence of detection or SLNB-positivity. Multivariable logistic regression was used for analysis of NAC-response and SLNB-results in molecular subtypes: HR-/HER2+, TNBC, HR+/HER2- and HR+/HER2+. Kaplan-Meyer and log-rank were used for survival analysis. Results: A total of 179 patients (50.5±10.1 years) were included. Of these, 39.7% achieved pCR (ypT0/Tis). HR-negative subtypes had higher pCR rates (HR-/HER2+: 59.4%; TNBC: 53.4%), with no cases of SLNB-positive. With residual disease, HR-/HER2+ and TNBC showed low rates of SLNB-positivity (6.7% and 10.3%) versus HR+ (HR+/HER2+: 20%; HR+/HER2-: 44%; p<0.001). Multivariable analysis identified independent predictors of SLNB-negativity (p<0.0001) to be: HR- [odds ratio (OR)=0.15; 95% confidence interval (CI): 0.06-0.37; p = 0.0001], HER2+ (OR=0.34; 95% CI: 0.14-0.81; p = 0.015) and high-grade Nottingham (OR=0.42; 95% CI: 0.18-0.99; p = 0.048). Disease-free survival showed worse outcomes with SLNB-positivity (p<0.0001), HR+/HER2- (p = 0.0277), larger tumor size (p = 0.002) and residual disease after NAC (p<0.0001). Conclusion: Patient selection based on NAC response, molecular subtype, and survival outcomes is a priority for establishing individualized therapeutic strategies after NAC. Molecular subtypes with higher pCR rates and lower rates of SLNB-positivity could benefit from non-invasive strategies that include omission of SLNB.

Spiritual well-being, faith, meaning in life, peace, and purpose in life for cancer-related fatigue: systematic review with meta-analysis and meta-regressions.

BACKGROUND: Cancer-related fatigue is associated with spiritual distress. Spiritual well-being, characterized by the presence of factors such as meaning in life or purpose in life, seems to play an important role in the management of symptoms of cancer. Currently, the number of studies evaluating the association between cancer-related fatigue and spiritual well-being is increasing and no systematic review has been conducted. AIM: To summarize the association between cancer-related fatigue and spiritual well-being, faith, meaning in life, peace, and purpose in life. DESIGN: A systematic review with meta-analysis. DATA SOURCES: The CINAHL, Embase, PsycINFO, and PubMed databases were searched from inception to 9 October 2023. We considered studies evaluating the cross-sectional or longitudinal association between cancer-related fatigue and the spiritual factors above mentioned. The Joanna Briggs Institute Checklist for Analytical Cross-Sectional Studies and the Quality in Prognosis Studies tool assessed the methodological quality of cross-sectional and longitudinal studies, respectively. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system rated the certainty of evidence. Meta-analyses, meta-regressions, subgroup meta-analyses, and sensitivity analyses were conducted. RESULTS: A total of 13 studies were included and no longitudinal findings were found. One meta-analysis showed that cancer-related fatigue may be negatively correlated with spiritual well-being (r = - 0.37 (95%CI - 0.44 to - 0.28) p < 0.01). In addition, another meta-analysis found the correlation between cancer-related fatigue and faith was not statistically significant (r = - 0.25 (95%CI - 0.66 to 0.28) p = 0.36). CONCLUSIONS: Cancer-related fatigue may be correlated with spiritual well-being. However, the certainty of evidence was very low across the meta-analyzed outcomes. IMPLICATIONS FOR CANCER SURVIVORS: A negative correlation was observed between spiritual well-being and cancer-related fatigue.

The prevalence of anxiety and depression in cancer around the world: An overview of systematic reviews evaluating 128 meta-analyses.

BACKGROUND: This overview of systematic reviews with meta-analysis summarized the prevalence of anxiety and depression in different types of tumors around the world. METHODS: The quality of reviews was assessed. The degree of overlap between reviews was calculated. The regional prevalence of anxiety and depression was shown in the main text based on the World Health Organization regions. RESULTS: Twenty-five reviews including 128 meta-analyses of interest were selected. The pooled prevalence of anxiety in breast tumors was in Africa (19 %), the Americas (38 %), Eastern Mediterranean (56 %), Europe (38 %), South-East Asia (42 %), and Western Pacific (26 %). The pooled prevalence of depression in breast tumors was in Africa (40 %), the Americas (23-25 %), Eastern Mediterranean (49-51 %), Europe (27-29 %), South-East Asia (23-33 %), Western Pacific (29 %). The pooled prevalence of depression in digestive tumors was in the Americas (4-44 %), Eastern Mediterranean (42 %), Europe (20-27 %), South-East Asia (66 %), and Western Pacific (24-40 %). The pooled national prevalence of anxiety and depression was mainly evaluated in China and Iran. LIMITATIONS: Important methodological issues were identified. For example, no reviews judged the certainty of evidence. CONCLUSIONS: The Eastern Mediterranean region showed the highest prevalence of anxiety and depression for breast tumors. The South-East Asian region showed the highest prevalence of depression for digestive tumors. In these regions, many countries are considered low-income and middle-income countries. Further research funding would help increase the investigation on this topic, which may allow the development of preventive strategies that reduce the prevalence of anxiety and depression.

Psychological and spiritual interventions to enhance meaning in adults diagnosed with cancer: a systematic review with meta-analysis and meta-regression.

OBJECTIVE: To summarize the evidence on the effectiveness that psychological and/or spiritual interventions may have to change the levels of meaning, measured with the Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being Scale (FACIT-Sp), in adults diagnosed with cancer. METHODS: Systematic review with meta-analysis and meta-regression. CINAHL (via EBSCOhost), Embase, PubMed, PsycINFO (via ProQuest), and the Cochrane Library were searched from inception to 21st October 2022. Manual searches were conducted. Only randomized clinical trials (RCTs) were included. The risk of bias was assessed with the Cochrane Risk of Bias tool 2. The Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach was used to judge the certainty of the evidence. RESULTS: Eight RCTs were included (N = 1682). Although some individual studies showed positive effects to enhance meaning using mindfulness or dignity therapy, the overall and individual meta-analyses showed a lack of effect of psychological and spiritual interventions in comparison to comparator interventions (MD (95%CI) = -0.19 (-0.45 to 0.06), p = 0.11, Tau2 = 0.0015, I2 = 2%). Publication bias was undetected (Egger's test = 0.35). Furthermore, no RCTs were judged to have a low risk of bias and the overall certainty of the evidence was judged as low. Meta-regression and subgroups meta-analyses also found possible sources of heterogeneity such as some cancer characteristics, the educational stage, or the religious affiliation. CONCLUSIONS: Despite some RCTs may show promising results following mindfulness or dignity therapy, no effects were observed in the meta-analysis. Moreover, important methodological and clinical concerns precluded us to make sound clinical recommendations with the available evidence.

Model-informed precision dosing of antimicrobial drugs in pediatrics: experiences from a pilot scale program.

Antibiotics are among the most utilized drugs in pediatrics. Nonetheless, there is a lack in pharmacokinetics information for this population, and dosing criteria may vary between healthcare centers. Physiological variability associated with maturation in pediatrics makes it challenging to reach a consensus on adequate dosing, which is further accentuated in more vulnerable groups, such as critically ill or oncology patients. Model-informed precision dosing is a useful practice that allows dose optimization and attainment of antibiotic-specific pharmacokinetic/pharmacodynamic targets. The aim of this study was to evaluate the needs of model-informed precision dosing of antibiotics in a pediatrics unit, at a pilot scale. Pediatric patients under antibiotic treatment were monitored with either a pharmacokinetic/pharmacodynamic optimized sampling scheme or through opportunistic sampling. Clindamycin, fluconazole, linezolid, meropenem, metronidazole, piperacillin, and vancomycin plasma concentrations were quantified through a liquid chromatography coupled to mass spectrometry method. Pharmacokinetic parameters were estimated using a Bayesian approach to verify pharmacokinetic/pharmacodynamic target attainment. A total of 23 pediatric patients aged 2 to 16 years were included, and 43 dosing regimens were evaluated; 27 (63%) of them required adjustments as follows: 14 patients were underdosed, 4 were overdosed, and 9 patients needed infusion rate adjustments. Infusion rate adjustments were mostly recommended for piperacillin and meropenem; daily doses were augmented for vancomycin and metronidazole, meanwhile linezolid was adjusted for under- and overdosing. Clindamycin and fluconazole regimens were not adjusted at all.  Conclusion: Results showcase a lack of antibiotic pharmacokinetic/pharmacodynamic target attainment (particularly for linezolid, vancomycin, meropenem, and piperacillin), and the need for model-informed precision dosing in pediatrics. This study provides pharmacokinetic evidence which can further improve antibiotic dosing practices. What is Known: • Model-informed precision dosing is performed in pediatrics to optimize the treatment of antimicrobial drugs such as vancomycin and aminoglycosides, while its usefulness is debated for other groups (beta-lactams, macrolides, etc.). What is New: • Vulnerable pediatric subpopulations, such as critically ill or oncology patients, can benefit the most from model-informed precision dosing of antibiotics. • Model-informed precision dosing of linezolid, meropenem, piperacillin, and vancomycin is particularly useful in pediatrics, and further research may improve dosing practices altogether.

Integrative model for self-perception of well-being in cancer.

PURPOSE: Continual illness uncertainty can affect how people perceive and interpret their well-being. Some cognitive and spiritual factors may be involved in the management of disruptive thoughts and emotions that can emerge during the experience of cancer. MATERIAL AND METHODS: An evidence-based integrative model was developed to evaluate and show the role that mindfulness, acceptance, self-efficacy, uncertainty, meaning, and purpose in life play in the self-perception of well-being in individuals with cancer. This evidence-based integrative model was conducted using relevant and selected studies. RESULTS: An integrative model for self-perception of well-being has been proposed. This model integrates evidence-based findings and provides clear principles for clinicians and researchers. This integrative model proposes that mindfulness, acceptance, self-efficacy perception, and uncertainty can predict how people with cancer perceive their well-being. The model also posits that meaning and purpose in life can act as mediators or moderators of this prediction. CONCLUSIONS: This integrative model involves the multidimensionality of human beings and facilitates the understanding of some key factors for the design of therapeutic approaches such as Acceptance & Commitment Therapy or Meaning-Centered Psychotherapy.IMPLICATIONS FOR REHABILITATIONMindfulness, acceptance, self-efficacy, uncertainty, meaning, and purpose in life can be highly relevant for clinical oncology.An integrative model is proposed to understand the combined influence of these factors on patients with cancer.This model may favor a better integration of well-known interventions, such as Mindfulness-based approaches, Acceptance and Commitment Therapy (ACT), and Meaning-Centered Psychotherapy (MCP).

Abscopal Effect, Extracellular Vesicles and Their Immunotherapeutic Potential in Cancer Treatment.

The communication between tumor cells and the microenvironment plays a fundamental role in the development, growth and further immune escape of the tumor. This communication is partially regulated by extracellular vesicles which can direct the behavior of surrounding cells. In recent years, it has been proposed that this feature could be applied as a potential treatment against cancer, since several studies have shown that tumors treated with radiotherapy can elicit a strong enough immune response to eliminate distant metastasis; this phenomenon is called the abscopal effect. The mechanism behind this effect may include the release of extracellular vesicles loaded with damage-associated molecular patterns and tumor-derived antigens which activates an antigen-specific immune response. This review will focus on the recent discoveries in cancer cell communications via extracellular vesicles and their implication in tumor development, as well as their potential use as an immunotherapeutic treatment against cancer.

Meaning and purpose in life, happiness, and life satisfaction in cancer: Systematic review with meta-analysis.

OBJECTIVE: To summarize current evidence on the potential cross-sectional and longitudinal association between meaning or purpose in life and subjective happiness or life satisfaction among cancer patients. METHODS: A systematic review with meta-analysis and meta-regression was conducted. CINAHL (via EBSCOhost), Embase, PubMed, and PsycINFO (via ProQuest) were searched from inception to 31 December 2022. In addition, manual searches were performed. The risk of bias in cross-sectional and longitudinal studies was assessed using the Joanna Briggs Institute Checklist for Analytical Cross-Sectional Studies and the Quality in Prognosis Studies tool, respectively. Certainty in the evidence was judged using the Grading of Recommendations, Assessment, Development, and Evaluations approach. Meta-regressions and sensitivity analyses were performed to explore potential sources of heterogeneity. RESULTS: We included 13 cross-sectional studies, comprising 12 different samples, and a longitudinal study. A total of 4968 individuals with cancer were interviewed across included studies. Certainty in the evidence was judged as very low for all outcomes, which was associated to serious concerns on risk of bias and imprecision of the results, and very serious concerns on indirectness of evidence. The assessed studies showed a marked heterogeneity in terms of participants' clinical (i.e., disease stage) and sociodemographic factors. A lack of reporting of these clinical and sociodemographic aspects were also evident among included studies. CONCLUSIONS: The wide number of methodological flaws detected in this systematic review preclude to make any clinical recommendation. More rigorous high-quality observational studies should guide future research on this topic.

Lower gastrointestinal bleeding as an uncommon form of presentation in a small intestine neuroendocrine tumor.

Neuroendocrine tumors (NETs) are rare, with an annual incidence of 10/100,000 inhabitants, with an increase in incidence in the last 30 years that probably is due to an improvement in diagnostic techniques. However, NETs the second neoplasia most prevalent advanced disease of the gastrointestinal tract due to its high survival. It´s way of presentation is usually with vague symptoms and often without an incidental diagnosis from the use of imaging techniques. A correct differential diagnosis will allow us its early diagnosis and its treatment. We present the case of a patient diagnosed with NET whose symptoms of presentation was lower gastrointestinal bleeding with a negative endoscopic study.

Lung Transplantation for Multiple Giant Hamartomas: First Case Report and Review of the Literature.

BACKGROUND: To assess lung transplant as a solution for a rare complication of giant lung hamartoma, in which surgical resection was discouraged because of severe underlying chronic lung disease. METHODS: A 54-year-old woman had an episode of severe acute hemoptysis. Imaging techniques showed 2 masses in the right lung as hamartomas and severe pulmonary emphysema. After resolution of the acute episode of hemoptysis, the case could have been solved with a right pneumonectomy; however, a single-lung transplant was performed because of the underlying chronic obstructive pulmonary disease. RESULTS: The outcome of the surgery was satisfactory, although a second operation was required because of bleeding. The patient was discharged and currently has a good quality of life, with no recurrence of the disease. The pathologic anatomy of the surgical specimen confirmed the diagnosis of multiple giant hamartomas. CONCLUSIONS: Lung transplant could be a feasible procedure to treat life-threatening complications of benign tumors in selected patients with pulmonary end-stage disease.

Double CD4/CD8-Positive, Nonpoikilodermic Mycosis Fungoides Expressing CD56 in a Young Man.

ABSTRACT: We report a case of mycosis fungoides (MF) in an 18-year-old man whose neoplastic T cells expressed CD4, CD8, and CD56, with no evidence of TCR-delta or Epstein-Barr virus (EBER) expression. Clinically, neither hypopigmentation nor hyperpigmentation nor poikilodermatous skin lesions were present, and the lesions subsided with oral corticoids and retinoids and environmental solar ultraviolet exposure. Our case represents the oldest patient reported so far with nonpoikilodermatous, CD8/CD56 MF and adds to the phenotypic diversity of MF in the pediatric population. This distinct phenotype does not seem to be linked to a more aggressive course than the classic CD-4 positive one.

Role of sarcopenia in the frailty transitions in older adults: a population-based cohort study.

BACKGROUND: Frailty and sarcopenia are age-associated syndromes that have been associated with the risk of several adverse events, mainly functional decline and death, that usually coexist. However, the potential role of one of them (sarcopenia) in modulating some of those adverse events associated to the other one (frailty) has not been explored. The aim of this work is to assess the role of sarcopenia within the frailty transitions and mortality in older people. METHODS: Data from the Toledo Study of Healthy Aging (TSHA) were used. TSHA is a cohort of community-dwelling older adults ≥65. Frailty was assessed according with the Frailty Phenotype (FP) and the Frailty Trait Scale-5 (FTS5) at baseline and at follow-up. Basal sarcopenia status was measured with the standardized Foundation for the National Institutes of Health criteria. Fisher's exact test and logistic regression model were used to determine if sarcopenia modified the transition of frailty states (median follow-up of 2.99 years) and Cox proportional hazard model was used for assessing mortality. RESULTS: There were 1538 participants (74.73 ± 5.73; 45.51% men) included. Transitions from robustness to prefrailty and frailty according to FP were more frequent in sarcopenic than in non-sarcopenic participants (32.37% vs. 15.18%, P ≤ 0.001; 5.76% vs. 1.12%; P ≤ 0.001, respectively) and from prefrailty-to-frailty (12.68% vs. 4.27%; P = 0.0026). Improvement from prefrail-to-robust and remaining robust was more frequent in non-sarcopenic participants (52.56% vs. 33.80%, P ≤ 0.001; 80.18% vs 61.15%, P ≤ 0.001, respectively). When classified by FTS5, this was also the case for the transition from non-frail-to-frail (25.91% vs. 4.47%, P ≤ 0.001) and for remaining stable as non-frail (91.25% vs. 70.98%, P ≤ 0.001). Sarcopenia was associated with an increased risk of progression from robustness-to-prefrailty [odds ratio (OR) 2.34 (95% confidence interval, CI) (1.51, 3.63); P ≤ 0.001], from prefrailty-to-frailty [OR(95% CI) 2.50 (1.08, 5.79); P = 0.033] (FP), and from non-frail-to-frail [OR(95% CI) 4.73 (2.94, 7.62); P-value ≤ 0.001]. Sarcopenia does not seem to modify the risk of death associated with a poor frailty status (hazard ratios (HR, 95%) P > 0.05). CONCLUSIONS: Transitions within frailty status, but not the risk of death associated to frailty, are modulated by the presence of sarcopenia.

Lactate-Loaded Nanoparticles Induce Glioma Cytotoxicity and Increase the Survival of Rats Bearing Malignant Glioma Brain Tumor.

A glioblastoma is an aggressive form of a malignant glial-derived tumor with a poor prognosis despite multimodal therapy approaches. Lactate has a preponderant role in the tumor microenvironment, playing an immunoregulatory role as well as being a carbon source for tumor growth. Lactate homeostasis depends on the proper functioning of intracellular lactate regulation systems, such as transporters and enzymes involved in its synthesis and degradation, with evidence that an intracellular lactate overload generates metabolic stress on tumor cells and tumor cell death. We propose that the delivery of a lactate overload carried in nanoparticles, allowing the intracellular release of lactate, would compromise the survival of tumor cells. We synthesized and characterized silica and titania nanoparticles loaded with lactate to evaluate the cellular uptake, metabolic activity, pH modification, and cytotoxicity on C6 cells under normoxia and chemical hypoxia, and, finally, determined the survival of an orthotopic malignant glioma model after in situ administration. A dose-dependent reduction in metabolic activity of treated cells under normoxia was found, but not under hypoxia, independent of glucose concentration. Lactated-loaded silica nanoparticles were highly cytotoxic (58.1% of dead cells) and generated significant supernatant acidification. In vivo, lactate-loaded silica nanoparticles significantly increased the median survival time of malignant glioma-bearing rats (p = 0.005) when administered in situ. These findings indicate that lactate-loaded silica nanoparticles are cytotoxic on glioma cells in vitro and in vivo.

Associations between frailty trajectories and frailty status and adverse outcomes in community-dwelling older adults.

BACKGROUND: The association between frailty and adverse outcomes has been clearly defined. Frailty is associated with age, but different frailty evolution patterns might determine the incidence of adverse outcomes at older ages. So far, few observational studies have examined how distinct frailty trajectories could be associated with differences in the risk of adverse events and assessing whether frailty trajectories could define risk of death, hospitalization, worsening, and incident disability better than one-off assessment. Our hypothesis is that prospective increases in frailty levels are associated with higher risk of adverse events compared with subjects that prospectively decreased frailty levels. METHODS: Participants' data were taken from the Toledo Study of Healthy Ageing. Frailty was evaluated using the Frailty Trait Scale 5 (FTS5), being 0 the lower (the most robust) and 50 the highest (the frailest) score. FTS5 scores at baseline and follow-up (median 5.04 years) were used to construct frailty trajectories according to group-based trajectory modelling (GBTM). Multivariate Cox proportional hazard and logistic regression models were used to explore associations between frailty status and trajectory membership and the adverse outcomes. Deaths were ascertained through the Spanish National Death Index. Disability was evaluated through the Katz Index. Hospitalization was defined as first admission to Toledo Hospital. RESULTS: Nine hundred and seventy-five older adults (mean age 73.14 ± 4.69; 43.38% men) were included. GBTM identified five FTS5 trajectories: worsening from non-frailty (WNF), improving to non-frailty (INF), developing frailty (DF), remaining frail (RF), and increasing frailty (IF). Subjects belonging to trajectories of increasing frailty scores or showing consistently higher frailty levels presented with an increased risk of mortality {DF [hazard ratio (HR), 95% confidence interval (CI)] = 2.01 [1.21-3.32]; RF = 1.92 [1.18-3.12]; IF = 2.67 [1.48-4.81]}, incident [DF (HR, 95% CI) = 2.06 (1.11-3.82); RF = 2.29 (1.30-4.03); IF = 3.55 (1.37-9.24)], and worsening disability [DF (HR, 95% CI) = 2.11 (1.19-3.76); RF = 2.14 (1.26-3.64); IF = 2.21 (1.06-4.62)], compared with subjects prospectively showing decreases in frailty levels or maintaining low FTS5 scores. A secondary result was a significant dose-response relationship between baseline FTS5 score and adverse events. CONCLUSIONS: Belonging to trajectories of prospectively increasing/consistently high frailty scores over time are associated with an increased risk of adverse outcomes compared with maintaining low or reducing frailty scores. Our results support the dynamic nature of frailty and the potential benefit of interventions aimed at reducing its levels on relevant and burdensome adverse outcomes.

ABSTRACT Objective: To report the results of our patients who underwent scoliosis correction surgery in relation to their quality of life. Introduction: Juvenile idiopathic scoliosis affects between 1 and 3% of the population during puberty. Treatment will be conservative in most cases. The goal of surgical treatment is to improve coronal and sagittal alignment. The SRS 22 questionnaire is a useful tool for assessing quality of life in these patients. Methods: A retrospective study of 22 patients submitted to corrective surgery for juvenile idiopathic scoliosis between October 2017 and January 2020 was conducted. All of them had curves greater than 45 degrees managed through instrumentation and arthrodesis. Post-surgical quality of life was assessed using the SRS 22 questionnaire. Results: The average age of our patients at the time of the intervention was 15.5 years with a predominance of female patients. The application of the SRS 22 questionnaire generated the following mean scores: pain 4.6, function 4.3, self-image 4.41, mental health 4.89, and satisfaction 5.0. Conclusions: The development of surgical techniques has allowed good results to be achieved in the treatment of scoliosis. The evaluation of our patients using the SRS 22 questionnaire reflects a good quality of life in the 5 parameters evaluated. The main limitations of this study were the small sample size and its retrospective nature. Level of Evidence III; Retrospective, longitudinal, descriptive, observational study.

Prevalence and characteristics of upper lumbar disc herniations in our practice: a retrospective analysis / Prevalência e características das hérnias lombares superiores em nosso meio: análise retrospectiva / Prevalencia y características de las hernias lumbares altas en nuestro medio: analisis retrospectivo

ABSTRACT Introduction: Upper lumbar disc herniations (ULDH) are considered infrequent injuries (1-11%). They present, most often in older adults, with special clinical features that make diagnosis and therapeutic decision-making difficult. The prevalence, location, and management of these herniations and the medical history of our patients were analyzed. Methods: Sex, age, injury level, previous surgery, and patient treatment data from July 2018 to May 2021 were collected retrospectively. During this period, 179 patients underwent surgery, 33 of whom patients presented ULDH. Results: Thirty-three patients were included in the study (18 male and 15 female). Ages ranged from 39 to 85 years, with a predominance of elderly patients. The levels operated were L1-L2 in seven patients, L2-L3 in ten patients, L3-L4 in fourteen patients, and surgery in two levels (L2-L3, L3-L4) in two patients. In our practice, microdiscectomy is the preferred approach and was performed in all cases, with the addition of fusion in four of the 33 patients. Finally, a history of low lumbar disc herniation (LLDH) surgery was found in 16 patients. Conclusions: In our population, ULDHs are a rare entity with lower prevalence at the higher lumbar levels. They occur more frequently in elderly patients and clinical presentation can vary, which is a challenge for surgeons. In older adults, the development of lumbar kyphosis due to vertebral wedging is considered a risk factor for the development of ULDH. Surgical management by microdiscectomy is considered a technique with good results for this pathology. Level of Evidence III; Retrospective, longitudinal, descriptive, observational study.

RESUMO Introdução: As hérnias de disco lombares altas (ULDH) são consideradas lesões infrequentes (1% a 11%). Ocorrem principalmente em idosos com características clínicas especiais que dificultam o diagnóstico e a decisão terapêutica. A prevalência, localização, o tratamento e a história de nossos pacientes foram analisados. Métodos: Dados sobre sexo, idade, nível das lesões, história cirúrgica e tratamento de nossos pacientes foram coletados retrospectivamente de julho de 2018 a maio de 2021. Nesse período, 179 pacientes foram operados, dos quais 33 apresentavam ULDH. Resultados: Trinta e três pacientes foram incluídos neste estudo, sendo 18 homens e 15 mulheres. A faixa etária variou de 39 a 85 anos, predominando os pacientes idosos. Os níveis operados foram L1-L2 em sete pacientes, L2-L3 em dez pacientes, L3-L4 em catorze pacientes e cirurgia em 2 níveis (L2-L3, L3-L4) em dois pacientes. Em nosso meio, a microdiscectomia é o tratamento de escolha, que foi realizado em todos os casos, adicionando fusão em 4 dos 33 pacientes. Finalmente, encontrou-se o antecedente de cirurgia de hérnia de disco lombar baixa (LLDH) em 16 pacientes. Conclusões: Em nosso meio, a ULDH é uma entidade rara e com menor prevalência em níveis lombares mais altos. Ocorrem com maior frequência em idosos e seu quadro clínico pode ser variado, o que representa um desafio para o cirurgião. Em idosos, o desenvolvimento de cifose lombar devido ao acunhamento vertebral é considerado um fator de risco para o desenvolvimento de ULDH. A cirurgia de microdiscectomia é considerada uma técnica com bons resultados nessa patologia. Nível de Evidência III; Estudo retrospectivo, transversal, descritivo, observacional.

RESUMEN Introducción: Las hernias discales lumbares altas (ULDH) son consideradas lesiones infrecuentes (1-11%). Se presentan principalmente en adultos mayores con características clínicas especiales que dificultan su diagnóstico y decisión terapéutica. La prevalencia, localización, manejo y antecedentes de nuestros pacientes fueron analizados. Métodos: Los datos con respecto a sexo, edad, nivel de lesión, antecedentes quirúrgicos y manejo de nuestros pacientes fueron recolectados retrospectivamente desde julio del 2018 hasta mayo del 2021. Durante este periodo 179 pacientes fueron operados, de los cuales 33 presentaron ULDH. Resultados: Treinta y tres pacientes fueron incluidos en éste estudio, de los cuales 18 eran hombres y 15 mujeres. Los rangos de edad variaron entre 39 y 85 años, predominando pacientes de la tercera edad. Los niveles intervenidos fueron L1-L2 en siete pacientes, L2-L3 en diez pacientes, L3-L4 en catorce pacientes y cirugía en 2 niveles (L2-L3, L3-L4) en dos pacientes. En nuestro medio, la microdiscectomía es el manejo preferido, el cual se realizó en todos los casos, agregando fusión en 4 de los 33 pacientes. Finalmente se encontró antecedente de cirugía por hernias discales lumbares bajas (LLDH) en 16 pacientes. Conclusiones: En nuestro medio, las ULDH son una entidad rara con menor prevalencia en niveles lumbares más altos. Se presentan con mayor frecuencia en personas de edad avanzada y su cuadro clínico puede ser variado, lo cual representa un reto para cirujano. En adultos mayores el desarrollo de cifosis lumbar por acuñamientos vertebrales se considera un factor de riesgo para el desarrollo de ULDH. El manejo quirúrgico mediante microdiscectomía se considera una técnica con buenos resultados en ésta patología. Nivel de Evidencia III; Estudio retrospectivo, transversal, descriptivo, observacional.
