A comparison of clinical characteristics and course predictors in early- and childhood-onset schizophrenia.

AIM: The aim of this study was to compare the clinical characteristics of childhood-onset schizophrenia (COS) and early-onset schizophrenia (EOS) during the first- episode psychosis and the stable period, to examine psychopharmacological treatment approaches, and to investigate potential predictive factors for prognosis. METHODS: Demographic, clinical, and psychopharmacological therapy data for 31 patients diagnosed with COS and 66 with EOS were retrieved from the file records in this multicenter study. Symptom distribution and disease severity and course were evaluated twice, in the acute psychotic stage and in the latest stable phase, during follow-up using the positive and negative syndrome scale (PANSS) and clinical global impression (CGI) scales. RESULTS: A statistically significant difference was observed between the groups' CGI improvement rates and median last stable stage PANSS positive, negative, and general psychopathology symptom scores (p = .005, p = .031, p = .005, and p = .012, respectively). Premorbid neurodevelopmental disorder and obsessive-compulsive disorder and comorbidities were more common in the COS group (p = .025 and p = .030, respectively), and treatment required greater multiple antipsychotic use in that group (p = .013). When the independent variables affecting the difference between pre- and post-treatment PANSS scores were examined using linear regression analysis, the model established was found to be statistically significant (F = 5.393; p = .001), and the group variable (p = .024), initial disease severity (p = .001), and socioeconomic level (p = .022; p = .007) emerged as predictive factors for the disease course. CONCLUSION: Although early diagnosis and treatment is an important factor in improving prognosis in schizophrenia, more specific predictors for schizophrenia need to be identified. Additionally, preventive programs and pharmacological methods need to be developed in children with neurodevelopmental problems, particularly those from low socioeconomic status families.

Clinical effectiveness of a modified muscle sparing posterior technique compared with a standard lateral approach in hip hemiarthroplasty for displaced intracapsular fractures (HemiSPAIRE): a multicenter, parallel-group, randomized controlled trial.

Objectives: Assess the effect of a modified muscle sparing posterior approach; SPAIRE (Save Piriformis and Internus, Repairing Externus), in hip hemiarthroplasty for displaced intracapsular fractures on postoperative mobility and function compared with a standard lateral approach. Design: Pragmatic, superiority, multicenter, parallel-group, randomized controlled trial (with internal pilot). Participants, ward staff, and research staff conducting postoperative assessments were blinded to allocation. A CTU allocated treatments centrally using computer-generated lists. Setting: Six hospitals in Southwest England, recruiting November 25, 2019-April 25, 2022. Participants: 244 adults (≥60 years) requiring hip hemiarthroplasty (122 allocated to each approach). 90 and 85 participants allocated to SPAIRE and lateral, respectively, had primary outcome data within the prespecified data collection window. Interventions: Surgery using SPAIRE or standard lateral approach. Follow-up 3 days and 120 days postoperation. Main outcome measure: Oxford Hip Score (OHS), via telephone at 120 days. Secondary outcomes: function and mobility (3 days), pain (3 days, 120 days), discharge destination, length of hospital stay, complications and mortality (within 120 days), quality of life and place of residence (120 days). Results: Participants' mean age was 84.6 years (SD 7.2); 168 (69%) were women. Primary outcome: little evidence of a difference in OHS at 120 days; adjusted mean difference (SPAIRE-lateral) -1.23 (95% CI -3.96 to 1.49, p=0.37). Secondary outcomes: indication of lower participant-reported pain at 3 days in SPAIRE arm; no differences between arms for remaining outcomes. Conclusions: Participants' mobility and function are similar in the short term (3 days) and longer term (120 days), whether receiving the SPAIRE or lateral approach. Neither approach confers benefit over the other in terms of length of hospital stay, return to prefracture residence, survival within 120 days, or quality of life at 120 days. Participants receiving SPAIRE approach may experience less pain in the early postoperative period. Modifying the posterior approach in hip hemiarthroplasty to the SPAIRE approach gives equivalent patient outcomes to the lateral approach within 120 days. Trial registration number: NCT04095611.

Clinical validation of the nursing outcome "Swallowing status: pharyngeal phase" in patients with laryngeal cancer.

AIMS AND OBJECTIVES: This study aimed to clinically validate the nursing outcome "Swallowing status: pharyngeal phase" (1013). METHODS: A two-stage study was designed: (1) Chinese translation and cultural adaptation and (2) clinical validation. Internal consistency and interrater reliability tests were performed on 285 patients with laryngeal cancer, and an additional 130 patients were randomly selected from the 285 patients as an independent sample. Criterion-related validity tests were performed using the standardized swallowing assessment (SSA). Nursing outcome sensitivity was detected by scoring two time points. RESULTS: The Cronbach's alpha coefficients were 0.951 for the nursing outcome and 0.942-0.965 for each indicator. The interclass correlation coefficient (ICC) values for each indicator ranged from 0.73 to 0.929. The scores of the nursing outcome were negatively correlated with the SSA scores (r = -0.555, p < 0.01). With the exception of two indicators, there was a significant difference (p < 0.05) between the total scores of the scale and its 11 indicator scores for the two time points. The results indicated that the nursing outcome "Swallowing status: pharyngeal phase" (1013) exhibited satisfactory psychometric properties and high sensitivity to change. CONCLUSIONS: The nursing outcome "Swallowing status: pharyngeal phase" (1013) demonstrated good reliability, validity, and sensitivity in patients with laryngeal cancer. IMPLICATIONS FOR NURSING PRACTICE: The nursing outcome "Swallowing status: pharyngeal phase" (1013) can be used to assess swallowing function in patients with laryngeal cancer and provide guidance for the development of rehabilitation intervention plans and nursing care.

Evaluation of the Concept of Value-Based Healthcare Applied to an Integrated Palliative Care Program in Colombia.

OBJECTIVE: This study aimed to evaluate the "Value-Based Healthcare" concept of an integrated palliative care (PC) program in Bogotá, Colombia, through the measurement of health outcomes and care costs in the last 3 months of life. METHODS: A multicenter, retrospective cohort study that included patients ≥18 years old who died in 2020 due to medical conditions amenable to PC. The measured health outcomes included pain, wellbeing, comfort, quality of life (QOL), and satisfaction. We analyzed the behavior of overall care costs during the last 3 months of the patients' lives and controlled for the effect of exposure to the program, considering the disease type and insurance coverage, using a linear regression model, nearest-neighbor matching, and sensitivity analysis. RESULTS: Among patients exposed to the program, the mean pain score was 2.1/10 (± 1.3) and wellbeing was rated at 3.5/10 (± 1.0), comfort at 1.6/24 (± 1.3), QOL at 3.6/5.0 (± 0.17), and satisfaction at 9.3/100 (± 0.15). The positive changes in these scores were greater for patients who remained in the program for over 3 months. Cost reduction was demonstrated in the last 90 days of life, with statistically significant and chronologically progressive savings during the last 30 days of life exceeding 5 million pesos per patient (P < .05). CONCLUSIONS: This study demonstrated the success of PC in reducing pain, improving wellbeing and QOL, providing comfort, and ensuring high levels of satisfaction. Moreover, PC is an effective value-based healthcare strategy and can significantly enhance the efficiency of healthcare services by reducing end-of-life healthcare costs.

Alternatives to the P value: connotations of significance.

The statistical significance of a clinical trial analysis result is determined by a mathematical calculation and probability based on null hypothesis significance testing. However, statistical significance does not always align with meaningful clinical effects; thus, assigning clinical relevance to statistical significance is unreasonable. A statistical result incorporating a clinically meaningful difference is a better approach to present statistical significance. Thus, the minimal clinically important difference (MCID), which requires integrating minimum clinically relevant changes from the early stages of research design, has been introduced. As a follow-up to the previous statistical round article on P values, confidence intervals, and effect sizes, in this article, we present hands-on examples of MCID and various effect sizes and discuss the terms statistical significance and clinical relevance, including cautions regarding their use.

Establishing Optimal Control Cohorts for Phase 1 Trials: Retrospective Analysis of Clinical and Biological Outcomes in Neonates and Infants Undergoing Two-Ventricle Repair.

Phase 1 trials are primarily conducted to evaluate the safety and feasibility of new interventions, usually without recruiting control patients. This retrospective study aims to characterize clinical and biological outcomes in historical and contemporary cases of neonates and infants undergoing two-ventricle repair to facilitate future secondary endpoint analyses for such trials. This retrospective study included neonates/infants (ages ≤ 6 months) who underwent two-ventricle repair between 2015 and 2021 using the same criteria as our phase 1 trial (n = 199). Patients were allocated into the ventricular septal defect (n = 61), the Tetralogy of Fallot (TOF, n = 88), and the transposition of the great arteries (n = 50) groups with an additional comparison between two eras (2015-2019 vs. 2020-2021). Patient characteristics and most variables assessed were different between the three diagnostic groups indicating the importance of diagnostic matching for secondary analyses. Although the era did not alter cerebral/somatic oxygenation, ventricular function, neuroimaging findings, and complication rates, we observed improvement of inotropic and/or vasoactive-inotropic scores in all groups during the more recent era. In 2020-2021, the age and the body weight at the operation were higher, and hospital stay was shorter in the TOF group, suggesting the possible impact of the pandemic. Results also indicated that matching altered characteristics such as age at operation that may limit the temporal effects and optimize secondary analyses. Using optimal contemporary cases and historical data based on this study will assist in developing a comprehensive study design for a future efficacy/effectiveness trial.

The effect of consultations performed by specialised nurses or advanced nurse practitioners on patient and organisational outcomes in patients with complex health conditions: An umbrella review.

BACKGROUND: Policymakers and researchers often suggest that nurses may play a crucial role in addressing the evolving needs of patients with complex conditions, by taking on advanced roles and providing nursing consultations. Nursing consultations vary widely across settings and countries, and their activities range from complementing to substituting traditional physician-led consultations or usual care. OBJECTIVE: This study was aimed at describing the effects of nursing consultations with patients with complex conditions in any setting on patient outcomes (quality of life, physical status, psychosocial health, health behaviour, medication adherence, mortality, anthropometric and physiological outcomes, and patient satisfaction) and organisational outcomes (health resource use and costs). DESIGN: Umbrella review. METHODS: We followed the Joanna Briggs Institute method for umbrella reviews. We searched PubMed, Embase, Cochrane Database of Systematic Reviews and CINAHL to identify relevant articles published in English, Dutch, French, Spanish or German between January 2013 and February 2023. We included systematic literature reviews, with or without meta-analyses, that included randomised controlled trials conducted in high-income countries. Reviews were eligible if they pertained to consultations led by specialised nurses or advanced nurse practitioners. Article selection, data extraction and quality appraisal were performed independently by at least two reviewers. RESULTS: We included 50 systematic reviews based on 473 unique trials. For all patient outcomes, nursing consultations achieved effects at least equivalent to those of physician-led consultations or usual care (i.e., non-inferiority). For quality of life, health behaviour, medication adherence, mortality and patient satisfaction, more than half the meta-analyses found statistically significant effects in favour of nursing consultations (i.e., superiority). Cost results must be interpreted with caution, because very few and heterogeneous cost-related data were extracted, and the methodological quality of the cost analyses was questionable. Narrative syntheses confirmed the overall conclusions of the meta-analyses. CONCLUSIONS: The effects of nursing consultations on patients with complex health conditions across healthcare settings appear to be at least similar to physician-led consultations or usual care. Nursing consultations appear to be more effective than physician-led consultations or usual care in terms of quality of life, health behaviour, mortality, patient satisfaction and medication adherence. Further analysis of the primary data is necessary to determine the patient populations and settings in which nursing consultations are most effective. Moderate study quality, diversity amongst and within systematic reviews, and quality of reporting hamper the strength of the findings.

Outcomes and Impact of Pre-ECMO Clinical Course in Severe COVID-19-Related ARDS Treated with VV-ECMO: Data from an Italian Referral ECMO Center.

Background: The efficacy of veno-venous extracorporeal membrane oxygenation (VV-ECMO) as rescue therapy for refractory COVID-19-related ARDS (C-ARDS) is still debated. We describe the cohort of C-ARDS patients treated with VV-ECMO at our ECMO center, focusing on factors that may affect in-hospital mortality and describing the time course of lung mechanics to assess prognosis. Methods: We performed a prospective observational study in the intensive care unit at the "Città della Salute e della Scienza" University Hospital in Turin, Italy, between March 2020 and December 2021. Indications and management of ECMO followed the Extracorporeal Life Support Organization (ELSO) guidelines. Results: The 60-day in-hospital mortality was particularly high (85.4%). Non-survivor patients were more frequently treated with non-invasive ventilatory support and steroids before ECMO (95.1% vs. 57.1%, p = 0.018 and 73.2% vs. 28.6%, p = 0.033, respectively), while hypertension was the only pre-ECMO factor independently associated with in-hospital mortality (HR: 2.06, 95%CI: 1.06-4.00). High rates of bleeding (85.4%) and superinfections (91.7%) were recorded during ECMO, likely affecting the overall length of ECMO (18 days, IQR: 10-24) and the hospital stay (32 days, IQR: 24-47). Static lung compliance was lower in non-survivors (p = 0.031) and differed over time (p = 0.049), decreasing by 48% compared to initial values in non-survivors. Conclusions: Our data suggest the importance of considering NIS among the common ECMO eligibility criteria and changes in lung compliance during ECMO as a prognostic marker.

Just a head knock? Emergency physicians need to get serious about concussion.

Attention and awareness regarding concussion injury in Australia have significantly increased in the last decade. Although most of this increase is because of discussion regarding concussions from sporting endeavours, the majority of concussions are from non-sport environments including motor vehicle crashes, workplace incidents, falls, accidents, assault and intimate partner violence. In all cases, hospital EDs are the first point of contact, yet as argued in our Opinion here, there are concerns regarding the consistency of care protocols, because of a number of reasons, as well as management and follow-up clinical practices. Our Opinion is to provide a constructive discussion as well as calling for ACEM to support research to provide evidence-based data. Finally, we provide some recommendations that could be implemented immediately to improve clinical practice for presentations of concussion injuries in EDs.

Recent Advances in Digital Technology in Implant Dentistry.

Digital technology has emerged as a transformative tool in dental implantation, profoundly enhancing accuracy and effectiveness across multiple facets, such as diagnosis, preoperative treatment planning, surgical procedures, and restoration delivery. The multiple integration of radiographic data and intraoral data, sometimes with facial scan data or electronic facebow through virtual planning software, enables comprehensive 3-dimensional visualization of the hard and soft tissue and the position of future restoration, resulting in heightened diagnostic precision. In virtual surgery design, the incorporation of both prosthetic arrangement and individual anatomical details enables the virtual execution of critical procedures (e.g., implant placement, extended applications, etc.) through analysis of cross-sectional images and the reconstruction of 3-dimensional surface models. After verification, the utilization of digital technology including templates, navigation, combined techniques, and implant robots achieved seamless transfer of the virtual treatment plan to the actual surgical sites, ultimately leading to enhanced surgical outcomes with highly improved accuracy. In restoration delivery, digital techniques for impression, shade matching, and prosthesis fabrication have advanced, enabling seamless digital data conversion and efficient communication among clinicians and technicians. Compared with clinical medicine, artificial intelligence (AI) technology in dental implantology primarily focuses on diagnosis and prediction. AI-supported preoperative planning and surgery remain in developmental phases, impeded by the complexity of clinical cases and ethical considerations, thereby constraining widespread adoption.

Longer Operative Time for Lower Extremity Bypass Surgery is Associated With Inferior Outcomes.

INTRODUCTION: This study aims to assess the association of operative time with the postoperative length of stay and unplanned return to the operating room in patients undergoing femoral to below knee popliteal bypasses, stratified by autologous vein graft or polytetrafluoroethylene (PTFE). MATERIALS AND METHODS: A retrospective analysis of vascular quality initiative database (2003-2021). The selected patients were grouped into the following: vein bypass (group I) and PTFE (group II) patients. Each group was further stratified by a median split of operative time (i.e., 210 min for autologous vein and 155 min for PTFE) to study the outcomes. The outcomes were assessed by univariate and multivariate approach. RESULTS: Of the 10,902 patients studied, 3570 (32.7%) were in the autologous vein group, while 7332 (67.3%) were in the PTFE group. Univariate analysis revealed autologous vein and PTFE graft recipients that had increased operative times were associated with a longer mean postoperative length of stay and a higher incidence of all-cause return to the operating room. In PTFE group, patients with prolonged operative times were also found to be associated with higher incidence of major amputation, surgical site infection, and cardiovascular events, along with loss of primary patency within a year. CONCLUSIONS: For patients undergoing femoral to below knee popliteal bypasses using an autologous vein or PTFE, longer operative times were associated with inferior outcomes. Mortality was not found to be associated with prolonged operative time.

Prognostic relevance of preoperative CA 19-9 values in stage III rectal adenocarcinoma: retrospective analysis and clinical implications.

Aim: To investigate prognostic significance of preoperative levels of the Carbohydrate anti-gen 19-9 (CA 19-9) in patients with stage III rectal adenocarcinoma who underwent a treatment at the Clinical Centre of the University of Sarajevo. Materials: A retrospective cohort study included 84 patients who underwent radical anterior rectal resection due to grade III rectal adenocarcinoma, followed by adjuvant chemotherapy according to the FOLFOX protocol (Oxaliplatin, Leucovorin, 5-Fluorouracil (5-FU)). The patients were divided into two groups according to CA 19-9 values (≥27 U/mL and <27 U/mL, respectively). Results: High pre-operative CA 19-9 values predicted an increased probability of postoperative metastases, especially liver, lung and abdominopelvic metastases, as well as three-year disease-free survival (3Y-DFS) and three-year overall survival (3Y-OS). The 3Y-DFS rate for patients with high CA 19-9 was 64.5%, while for those with low CA 19-9 it was 87.2%. The 3Y-OS rate for patients with high CA 19-9 was 89.8%, while for those with low CA 19-9 it was 65.7%. Univariate and multivariate regression analysis confirmed that a high level of CA 19-9 is an independent predictor for DFS and OS shorter than three years. Conclusion: Pre-operatively elevated values of CA 19-9 in rectal adenocarcinoma have a significant role in predicting the outcome in patients with stage III rectal adenocarcinoma.

Controversy on the CONVINCE study findings: the PRO take / Controvérsia sobre os achados do estudo CONVINCE: a perspectiva PRO

ABSTRACT The CONVINCE study, recently published in the New England Journal of Medicine, reveals a groundbreaking 23% reduction in the relative risk of all-cause mortality among end-stage kidney patients undergoing high convective volume hemodiafiltration. This significant finding challenges the conventional use of high-flux hemodialysis and offers hope for improving outcomes in chronic kidney disease patients. While some controversies surround the study's findings, including concerns about generalizability and the causes of death, it is essential to acknowledge the study's design and its main outcomes. The CONVINCE study, part of the HORIZON 2020 project, enrolled 1360 patients and demonstrated the superiority of hemodiafiltration in reducing all-cause mortality overall, as well as in specific patient subgroups (elderly, short vintage, non-diabetic, and those without cardiac issues). Interestingly, it was shown that hemodiafiltration had a protective effect against infection, including COVID-19. Future research will address sustainability, dose scaling effects, identification of subgroups especially likely to benefit and cost-effectiveness. However, for now, the findings strongly support a broader adoption of hemodiafiltration in renal replacement therapy, marking a significant advancement in the field.

RESUMO O estudo CONVINCE, publicado recentemente no New England Journal of Medicine, revela uma redução inovadora de 23% no risco relativo de mortalidade por todas as causas entre pacientes renais em estágio terminal submetidos à hemodiafiltração de alto volume de convecção. Esse achado significativo desafia o uso convencional da hemodiálise de alto fluxo e oferece esperança de melhoria dos desfechos em pacientes com doença renal crônica. Embora algumas controvérsias cerquem os achados do estudo, incluindo preocupações sobre a generalização e as causas de óbito, é essencial reconhecer o desenho do estudo e seus principais desfechos. O estudo CONVINCE, parte do projeto HORIZON 2020, inscreveu 1.360 pacientes e demonstrou a superioridade da hemodiafiltração na redução da mortalidade por todas as causas em geral, bem como em subgrupos específicos de pacientes (idosos, HD de curta duração, não diabéticos e aqueles sem problemas cardíacos). Curiosamente, demonstrou-se que a hemodiafiltração teve um efeito protetor contra infecções, incluindo a COVID-19. Pesquisas futuras abordarão sustentabilidade, efeitos de escalonamento da dose, identificação de subgrupos especialmente propensos a se beneficiar e a relação custo-benefício. No entanto, por ora, os achados apoiam fortemente uma adoção mais ampla da hemodiafiltração na terapia renal substitutiva, marcando um avanço significativo na área.

Determinants of multidrug-resistant tuberculosis among adults undergoing treatment for tuberculosis in Tigray Region, Ethiopia: a case-control study.

BACKGROUND: Multidrug-resistant tuberculosis is a type of tuberculosis that is resistant to at least the first-line antituberculosis drugs namely, rifampicin and isoniazid. However, most of these studies were limited only to a single hospital. Therefore, this study aimed to identify the determinants of multidrug-resistant tuberculosis among adults undergoing treatment for tuberculosis in the Tigray region of Ethiopia. METHODS: Hospital-based unmatched case-control study was conducted from 1 April 2019 to 30 June 2019. A simple random sampling method was used to select the required sample size. Variables at a p value less than 0.25 in bivariate analysis were entered into a multivariable analysis to identify the determinant factors of multidrug-resistant tuberculosis. Finally, the level of significance was declared at p<0.05. RESULTS: Rural residence (adjusted OR (AOR) 2.54; 95% CI 1.34 to 4.83), HIV (AOR 4.5; 95% CI 1.4 to 14.2), relapse (AOR 3.86; 95% CI 1.98 to 7.5), return after lost follow-up (AOR 6.29; 95% CI 1.64 to 24.2), treatment failure (AOR 5.87; 95% CI 1.39 to 24.8) were among the determinants of multidrug-resistant tuberculosis. CONCLUSION: Rural residence, HIV, relapses, return after lost follow-up and treatment failure were the identified determinant factors of multidrug-resistance tuberculosis.

Identifying spatial neglect - an updated systematic review of the psychometric properties of assessment tools in adults post-stroke.

Spatial neglect commonly occurs after a stroke, resulting in diverse impacts depending on the type and severity. There are almost 300 tools for assessing neglect, yet there is a lack of knowledge on the psychometric properties of these tools. The objective of this systematic review, registered on Prospero (CRD42021271779), was to determine the quality of the evidence for assessing spatial neglect, categorized by neglect subtype. The following databases were searched on 3rd May 2022 from database inception: Ovid Emcare, Embase, Ovid MEDLINE, APA PsycINFO, Web of Science (SCI-EXPANDED; SSCI; A&HCI; ESCI) and Scopus. All primary peer-reviewed studies (>5 participants) of adults post stroke, reporting any psychometric property of 33 commonly used neglect assessment tools were included. The COSMIN (COnsensus-based Standards for the selection of health Measurement INstruments) risk of bias tool was used to assess the methodological quality of the studies and summarize the psychometric properties of each tool. 164 articles were included, with a total of 12,463 people with stroke. The general quality of the evidence was poor and no one tool had high-quality evidence of both validity and reliability. Eleven tools show some promise as they meet the minimum criteria for good measurement properties for both validity and reliability.

Performance of multiple therapeutic approaches for palatal wound healing after soft tissue graft removal - an overview of systematic reviews.

OBJECTIVE: To overview the literature to answer the following question: "What is the performance of different therapies on wound healing and postoperative discomfort after palatal ASTG removal?" METHODS: SRs that evaluated the wound healing (WH), postoperative pain, bleeding, and analgesic consumption of patients submitted to de-epithelialized/free gingival grafts (FGG) or subepithelial connective tissue grafts (SCTG) removed from the palate were included. The searches were conducted on six white and two gray databases up to December 2023. Methodological quality was evaluated through AMSTAR 2. The synthesis of results was described as a narrative analysis. RESULTS: Ten SRs (involving 25 randomized clinical trials) related to low-level laser therapy (LLLT) (3), platelet-rich fibrin (PRF) (4), cyanoacrylate tissue adhesives (CTA) (2), and ozone therapy (OT) (1) were included in this overview. All techniques demonstrated improvements in WH. LLT, PRF, and CTA reduced pain and analgesic consumption. PRF and CTA reduced bleeding. Regarding methodological quality, the SRs were classified as critically low (2), low (5), moderate (2), or high quality (1). CONCLUSIONS: In SRs related to LLLT, PRF, CTA, and OT, the use of different therapies after palatal ASTG removal improved WH and postoperative discomfort. Due to the studies' low methodological quality and high heterogeneity, data should be interpreted with caution. CLINICAL RELEVANCE: The present overview compiles the evidence of SRs related to different therapies for WH and patients' postoperative experience and reveals that different treatments can significantly improve the clinical outcomes of patients who require ASTG removal for periodontal or peri-implant surgeries. REGISTRATION: PROSPERO registration number: CRD42022301257.

Total Knee Arthroplasty in Patients Who Have Skeletal Dysplasia: A Center's Experience With a Mean 9-Year Follow-Up.

BACKGROUND: Total knee arthroplasty (TKA) in patients who have skeletal dysplasia (SD) is a technically challenging surgery due to deformity, joint contracture, and associated comorbidities. Patients presenting with this condition have traditionally been treated with conservative measures, leading to poor outcomes. The aim of this study was to follow-up on patients who had SD following TKA, specifically with regards to clinical outcomes. METHODS: A total of 31 knees (22 patients) with SD that had undergone TKA in our institution were included in our study. The mean follow-up from index surgery was 110.3 months (range: 20 to 291). The type of dysplasia, implant used, and clinical outcomes with patient-reported outcome measures are presented. RESULTS: There were 8 patients (36.3%) who had a diagnosis of achondroplasia, followed by multiple epiphyseal dysplasia (31.8%) and spondyloepiphyseal dysplasia (22.7%). There were 14 men and 8 women who had a mean age of 51 years (range: 28 to 73). Custom implants were required in 12 cases (38.7%), custom jigs were used in 6 cases (19.4%), and robotic-assisted surgery was used in 2 (6.5%) TKAs. Hinged prostheses were used in 17 cases (54.8%), posterior-stabilized in 9 (29.0%), and cruciate-retaining implants in 5 (16.1%). There was 1 patient who sustained an intraoperative medial tibial plateau fracture treated with concomitant open reduction and internal fixation. There was 1 revision that occurred during the follow-up period with a patella resurfacing for continued anterior knee pain. Postoperatively, Oxford Knee Scores improved on average by 12.2 points. The 10-year and 20-year all-cause revision-free survival was 96.8, respectively. CONCLUSIONS: Despite the technical challenges and complexity associated with this unique patient cohort, we demonstrated excellent implant survivorship and clinical outcomes post-TKA with mid-term to long-term follow-up of more than 20 years. We recommend preoperative cross-sectional imaging for precise planning and implant templating with multidisciplinary team decision-making. Despite our results, functional outcomes remain inferior to primary arthroplasty within the general population, although we still recommend this treatment modality to appropriately counseled patients. LEVEL OF EVIDENCE: III.

Relationship Between Hand Strength and Function in Duchenne Muscular Dystrophy and Spinal Muscular Atrophy: Implications for Clinical Trials.

Background: Measurement of muscle strength and motor function is recommended in clinical trials of neuromuscular diseases, but the loss of hand strength at which motor function is impacted is not documented. Objectives: To establish the relationship between hand strength and function, and to determine the strength threshold that differentiates normal and abnormal hand function in individuals with Duchenne Muscular Dystrophy (DMD) or Spinal Muscular Atrophy (SMA). Methods: Maximal handgrip and key pinch strength were measured with the MyoGrip and MyoPinch dynamometers, respectively. Hand function was assessed using the MoviPlate, the Motor Function Measure items for distal upper limb (MFM-D3-UL) and the Cochin Hand Function Scale (CHFS). Results: Data from 168 participants (91 DMD and 77 SMA, age 6-31 years) were analyzed. Relationships between strength and function were significant (P < 0.001). Hand function was generally preserved when strength was above the strength threshold determined by Receiver-Operating Characteristic (ROC) analysis: For MFM-D3-UL, the calculated handgrip strength thresholds were 41 and 13% of the predicted strength for a healthy subject (% pred) and the key pinch strength thresholds were 42 and 26% pred for DMD and SMA, respectively. For the MoviPlate, handgrip strength thresholds were 11 and 8% pred and key pinch strength thresholds were 21 and 11% pred for DMD and SMA, respectively. For participants with sub-threshold strength, hand function scores decreased with decreasing strength. At equal % pred strength, individuals with SMA had better functional scores than those with DMD. Conclusions: Hand function is strength-dependent for most motor tasks. It declines only when strength falls below a disease-specific threshold. Therefore, therapies capable of maintaining strength above this threshold should preserve hand function.

Impact of the Alberta Stroke Program CT Score subregions on long-term functional outcomes in acute ischemic stroke: Results from two multicenter studies in China.

Background and Objectives: The Alberta Stroke Program CT Score (ASPECTS) is a widely used rating system for assessing infarct extent and location. We aimed to investigate the prognostic value of ASPECTS subregions' involvement in the long-term functional outcomes of acute ischemic stroke (AIS). Materials and Methods: Consecutive patients with AIS and anterior circulation large-vessel stenosis and occlusion between January 2019 and December 2020 were included. The ASPECTS score and subregion involvement for each patient was assessed using posttreatment magnetic resonance diffusion-weighted imaging. Univariate and multivariable regression analyses were conducted to identify subregions related to 3-month poor functional outcome (modified Rankin Scale scores, 3-6) in the reperfusion and medical therapy cohorts, respectively. In addition, prognostic efficiency between the region-based ASPECTS and ASPECTS score methods were compared using receiver operating characteristic curves and DeLong's test. Results: A total of 365 patients (median age, 64 years; 70% men) were included, of whom 169 had poor outcomes. In the reperfusion therapy cohort, multivariable regression analyses revealed that the involvement of the left M4 cortical region in left-hemisphere stroke (adjusted odds ratio [aOR] 5.39, 95% confidence interval [CI] 1.53-19.02) and the involvement of the right M3 cortical region in right-hemisphere stroke (aOR 4.21, 95% CI 1.05-16.78) were independently associated with poor functional outcomes. In the medical therapy cohort, left-hemisphere stroke with left M5 cortical region (aOR 2.87, 95% CI 1.08-7.59) and caudate nucleus (aOR 3.14, 95% CI 1.00-9.85) involved and right-hemisphere stroke with right M3 cortical region (aOR 4.15, 95% CI 1.29-8.18) and internal capsule (aOR 3.94, 95% CI 1.22-12.78) affected were related to the increased risks of poststroke disability. In addition, region-based ASPECTS significantly improved the prognostic efficiency compared with the conventional ASPECTS score method. Conclusion: The involvement of specific ASPECTS subregions depending on the affected hemisphere was associated with worse functional outcomes 3 months after stroke, and the critical subregion distribution varied by clinical management. Therefore, region-based ASPECTS could provide additional value in guiding individual decision making and neurological recovery in patients with AIS.

Social determinants of gastrointestinal malformation mortality in Brazil: a national study.

Introduction: In Brazil, approximately 5% are born with a congenital disorder, potentially fatal without surgery. This study aims to evaluate the relationship between gastrointestinal congenital malformation (GICM) mortality, health indicators, and socioeconomic factors in Brazil. Methods: GICM admissions (Q39-Q45) between 2012 and 2019 were collected using national databases. Patient demographics, socioeconomic factors, clinical management, outcomes, and the healthcare workforce density were also accounted for. Pediatric Surgical Workforce density and the number of neonatal intensive care units in a region were extracted from national datasets and combined to create a clinical index termed 'NeoSurg'. Socioeconomic variables were combined to create a socioeconomic index termed 'SocEcon'. Simple linear regression was used to investigate if the temporal changes of both indexes were significant. The correlation between mortality and the different indicators in Brazil was evaluated using Pearson's correlation coefficient. Results: Over 8 years, Brazil recorded 12804 GICM admissions. The Southeast led with 6147 cases, followed by the Northeast (2660), South (1727), North (1427), and Midwest (843). The North and Northeast reported the highest mortality, lowest NeoSurg, and SocEcon Index rates. Nevertheless, mortality rates declined across regions from 7.7% (2012) to 3.9% (2019), a 51.7% drop. The North and Midwest experienced the most substantial reductions, at 63% and 75%, respectively. Mortality significantly correlated with the indexes in nearly all regions (p<0.05). Conclusion: Our study highlights the correlation between social determinants of health and GICM mortality in Brazil, using two novel indexes in the pediatric population. These findings provide an opportunity to rethink and discuss new indicators that could enhance our understanding of our country and could lead to the development of necessary solutions to tackle existing challenges in Brazil and globally.
