Assessing Functional Outcomes of Partial Versus Radical Nephrectomy for T1b-T2 Renal Masses: Results from a Multi-institutional Collaboration.

BACKGROUND: Deterioration of renal function is associated with increased all-cause mortality. In renal masses larger than 4 cm, whether partial versus radical nephrectomy (PN vs. RN) might affect long-term functional outcomes is unknown. This study tested the association between PN versus RN and postoperative acute kidney injury (AKI), recovery of at least 90% of the preoperative estimated glomerular filtration rate (eGFR) at 1 year, upstaging of chronic kidney disease (CKD) one stage or more at 1 year, and eGFR decline of 45 ml/min/1.73 m2 or less at 1 year. METHODS: Data from 23 high-volume institutions were used. The study included only surgically treated patients with single, unilateral, localized, clinical T1b-2 renal masses. Multivariable logistic regression analyses were performed. RESULTS: Overall, 968 PN patients and 325 RN patients were identified. The rate of AKI was lower in the PN versus the RN patients (17% vs. 58%; p < 0.001). At 1 year after surgery, for the PN versus the RN patients, the rate for recovery of at least 90% of baseline eGFR was 51% versus 16%, the rate of CKD progression of ≥ 1 stage was 38% versus 65%, and the rate of eGFR decline of 45 ml/min/1.73 m2 or less was 10% versus 23% (all p < 0.001). Radical nephrectomy independently predicted AKI (odds ratio [OR], 7.61), 1-year ≥ 90% eGFR recovery (OR, 0.30), 1-year CKD upstaging (OR, 1.78), and 1-year eGFR decline of 45 ml/min/1.73 m2 or less (OR, 2.36) (all p ≤ 0.002). CONCLUSIONS: For cT1b-2 masses, RN portends worse immediate and 1-year functional outcomes. When technically feasible and oncologically safe, efforts should be made to spare the kidney in case of large renal masses to avoid the hazard of glomerular function loss-related mortality.

Learning curve for intracorporeal robotic Padua ileal bladder: 10-year functional assessment from a high-volume single-centre series.

OBJECTIVES: To assess the impact of the learning curve (LC) on perioperative and long-term functional outcomes of a consecutive single-centre series of robot-assisted radical cystectomy with Padua intracorporeal orthotopic neobladder. PATIENTS AND METHODS: Patients treated between 2013 and 2022 were included, with ≥1 year of follow-up. The entire cohort was divided in tertiles. Categorical and continuous variables were compared. Joinpoint regression analysis was used to identify significant changes over the decade in linear slope of the 1-year day- and night-time continence. Uni- and multivariable Cox regression analyses identified predictors of day- and night-time continence recovery. Day-time continence was defined as 'totally dry' (no pads), night-time continence as pad wetness ≤50 mL (one safety pad). RESULTS: Overall, 200 patients were included. The mean hospital stay (P = 0.002) and 30-day complications (P = 0.04) significantly reduced over time; the LC significantly impacted on Trifecta achievement (P < 0.001). The 1-year day- and night-time continence probabilities displayed a significant improving trend (day-time continence annual average percentage change [AAPC] 11.45%, P < 0.001; night-time continence AAPC 10.05%, P = 0.009). The LC was an independent predictor of day- (hazard ratio [HR] 1.008; P < 0.001) and night-time continence (HR 1.004; P = 0.03) over time. CONCLUSION: Patients at the beginning of the LC had significantly longer hospitalisations, more postoperative complications, and lower Trifecta rates. At the 10-year analyses, we observed a significant improving trend for both the 1-year day- and night-time continence probabilities, highlighting the crucial role of the LC. However, we are unable to assess the case volume needed to achieve a plateau in terms of day- and night-time continence rates.

Retzius sparing robot-assisted radical prostatectomy: optimizing functional results.

PURPOSE: The aim of this study is to critically evaluate the existing body of evidence regarding the efficacy of Retzius-sparing radical prostatectomy (RS-RARP) in achieving improved functional outcomes. Moreover, we explored possible strategies to further optimize functional outcomes. METHODS: Following PRISMA guidelines, a systematic review (PROSPERO ID CRD42024539915) was performed on 9th September 2023 on PubMed, Scopus, and Web of Science. Only original articles in the English language reporting functional outcomes after RS-RARP were included. RESULTS: Overall, the search string yielded 99 results on PubMed, 122 on Scopus, and 120 on Web Of Science. After duplicate exclusion, initial screening and eligibility evaluation, a total of 47 studies were included in the qualitative analysis, corresponding to a cohort of 13.196 patients. All studies reported continence recovery. RS-RARP appeared to achieve better and faster continence recovery compared to S-RARP. However, it should be noted that continence definition was heterogeneous and not based on validated condition-specific questionnaires. Seven (15%) studies provided for any sort of rehabilitation for urinary incontinence after RS-RARP. 22 studies analyzed potency recovery rates, showing no difference between RS-RARP and S-RARP. The evaluation of this outcome poses a great challenge due to the lack of standardized assessment tools and reporting methods. Only two studies reported on the consistent use of post-operative PDE5i as penile rehabilitation. CONCLUSIONS: The current review highlights the satisfactory functional results of Retzius-sparing robot assisted radical prostatectomy, which holds true irrespective of disease stage and prostate volume, with promising results even in patients previously treated for BPH or in the salvage setting. How can we optimize those results? The answer does not probably lie in further refinement of the surgical technique, but in giving greater attention to patient counselling and rehabilitation strategies in order to minimize regret and maximize satisfaction.

Exploring causal association between circulating inflammatory cytokines and functional outcomes following ischemic stroke: A bidirectional Mendelian randomization study.

OBJECTIVES: Previous observational studies have indicated correlations between various inflammatory cytokines and functional outcomes following ischemic stroke (IS); however, the causality remains unclear. We aimed to further evaluate the causal association between 41 circulating inflammatory cytokines and functional outcomes following IS. METHODS: Two-sample bidirectional Mendelian randomization (MR) analysis was used in this study. The genetic variation of 41 circulating inflammatory cytokines were derived from genome-wide association study (GWAS) data of European ancestry (n = 8293). The corresponding genetic association of functional outcomes following IS were derived from European ancestry GWAS data (n = 6021). RESULTS: Inverse variance weighted (IVW) analysis showed that genetically predicted increased levels of regulation and activation in normal T-cell expression and secretion factor (RANTES/CCL5) and eosinophilic chemotactic factor (EOTAXIN/CCL11) were positively correlated with the increased adverse functional outcomes (modified Rankin Scale [mRS≥3] following IS (OR: 1.40, 95% CI: 1.002-1.96, p = 0.049; OR: 1.33, 95% CI: 1.15-1.54, p = 0.0001). Interleukin 18 (IL-18) level might be the downstream consequence of adverse functional outcomes following IS (ß: -0.09, p = 0.039). Other inflammatory cytokines and functional outcomes following IS did not appear to be causally related. CONCLUSIONS: This study suggests a causality between inflammation and adverse functional outcomes following IS. RANTES (CCL5) and EOTAXIN (CCL11) may be the upstream factors of adverse functional outcomes following IS, while IL-18 may be the downstream effect of adverse functional outcomes following IS. Whether these cytokines can be used to predict or improve adverse functional outcomes after IS requires further researches.

Blood pressure variability in acute stroke: Risk factors and association with functional outcomes at 1 month.

BACKGROUND AND PURPOSE: Blood pressure variability, in acute stroke, may be an important modifiable determinant of functional outcome after stroke. In a large international cohort of participants with acute stroke, it was sought to determine the association of blood pressure variability (in the early period of admission) and functional outcomes, and to explore risk factors for increased blood pressure variability. PATIENTS AND METHODS: INTERSTROKE is an international case-control study of risk factors for first acute stroke. Blood pressure was recorded at the time of admission, the morning after admission and the time of interview in cases (median time from admission 36.7 h). Multivariable ordinal regression analysis was employed to determine the association of blood pressure variability (standard deviation [SD] and coefficient of variance) with modified Rankin score at 1-month follow-up, and logistic regression was used to identify risk factors for blood pressure variability. RESULTS: Amongst 13,206 participants, the mean age was 62.19 ± 13.58 years. When measured by SD, both systolic blood pressure variability (odds ratio 1.13; 95% confidence interval 1.03-1.24 for SD ≥20 mmHg) and diastolic blood pressure variability (odds ratio 1.15; 95% confidence interval 1.04-1.26 for SD ≥10 mmHg) were associated with a significant increase in the odds of poor functional outcome. The highest coefficient of variance category was not associated with a significant increase in risk of higher modified Rankin score at 1 month. Increasing age, female sex, high body mass index, history of hypertension, alcohol use, and high urinary potassium and low urinary sodium excretion were associated with increased blood pressure variability. CONCLUSION: Increased blood pressure variability in acute stroke, measured by SD, is associated with an increased risk of poor functional outcome at 1 month. Potentially modifiable risk factors for increased blood pressure variability include low urinary sodium excretion.

Patients Lost to Follow-up After Injury: Who are They and What are Their Long-Term Outcomes?

INTRODUCTION: Trauma patients are at high risk for loss to follow-up (LTFU) after hospital discharge. We sought to identify risk factors for LTFU and investigate associations between LTFU and long-term health outcomes in the trauma population. METHODS: Trauma patients with an Injury Severity Score ≥9 admitted to one of three Level-I trauma centers, 2015-2020, were surveyed via telephone 6 mo after injury. Univariate and multivariate analyses were performed to assess factors associated with LTFU and several long-term outcomes. RESULTS: Of 3609 patients analyzed, 808 (22.4%) were LTFU. Patients LTFU were more likely to be male (71% versus 61%, P = 0.001), Black (22% versus 14%, P = 0.003), have high school or lower education (50% versus 42%, P = 0.003), be publicly insured (23% versus 13%, P < 0.001), have a penetrating injury (13% versus 8%, P = 0.006), have a shorter length of stay (3.64 d ± 4.09 versus 5.06 ± 5.99, P < 0.001), and be discharged home without assistance (79% versus 50%, P < 0.001). In multivariate analyses, patients who followed up were more likely to require assistance at home (6% versus 11%; odds ratio [OR] 2.23, 1.26-3.92, P = 0.005), have new functional limitations (11% versus 26%; OR 2.91, 1.97-4.31, P = < 0.001), have daily pain (30% versus 48%; OR 2.11, 1.54-2.88, P = < 0.001), and have more injury-related emergency department visits (7% versus 10%; OR 1.93, 1.15-3.22, P = 0.012). CONCLUSIONS: Vulnerable populations are more likely to be LTFU after injury. Clinicians should be aware of potential racial and socioeconomic disparities in follow-up care after traumatic injury. Future studies investigating improvement strategies in follow-up care should be considered.

Patient reported outcomes after multivisceral resection for advanced rectal cancers in female patients.

INTRODUCTION: Multivisceral resections for rectal cancer can lead to long-term functional disturbances. This study aims to evaluate the quality-of-life outcomes in female patients who underwent multivisceral resection for rectal cancer, specifically focusing on urinary and sexual functions. METHODS: A cross-sectional study was conducted on female patients who underwent multivisceral rectal resections. Quality of life was assessed using the EORTC QLQ-CR29. RESULTS: Out of 198 female patients that underwent multivisceral resections, 69 were assessable for functional outcomes. The uterus was removed in 42 patients (61%), and the posterior vaginal wall in 34 (49%). A vaginal reconstructive procedure was carried out in 30% (21 patients). Patients reported the most troubles with urinary frequency (mean: 69.6; SD: 9.9), hair loss (mean: 64.7; SD: 13.9), pain during intercourse (mean: 44; SD: 40.7), and bowel frequency (mean: 36.9; SD: -10.7) in this order. Amongst the functional scales, anxiety about future health (mean: 42.5; SD: -018.9) and interest in sex (mean: 57.2; SD: 33.2) scored the lowest. CONCLUSION: Multivisceral rectal resections in female patients are associated with physical and psychosocial changes resulting in urinary and bowel complaints, anxiety about future health, poor sexual health, and pain.

Low anterior resection syndrome phenotypes-Different symptom profiles for different patients.

AIM: Attention is increasingly being turned to functional outcomes as being central to colorectal cancer (CRC) survivorship. The current literature may underestimate the impact of evacuatory dysfunction on patient satisfaction with bowel function after anterior resection (AR) for CRC. The aim of this study was to investigate the impact of post-AR symptoms of storage and evacuatory dysfunction on patient satisfaction and health-related quality of life (HRQoL). METHOD: A cross-sectional study was performed at an Australian hospital of patients post-AR for CRC (2012-2021). The postoperative bowel function scores used were: low anterior resection syndrome (LARS), St Mark's incontinence, Cleveland Clinic constipation and Altomare obstructive defaecation syndrome scores. Eight 'storage' and 'evacuatory' dysfunction symptoms were derived. A seven-point Likert scale measured patient satisfaction. The SF36v2® measured HRQoL. Linear regression assessed the association between symptoms, patient satisfaction and HRQoL. RESULTS: Overall, 248 patients participated (mean age 70.8 years, 57.3% male), comprising 103 with rectal cancer and 145 with sigmoid cancer. Of the symptoms that had a negative impact on patient satisfaction, six reflected evacuatory dysfunction, namely excessive straining (p < 0.001), one or more unsuccessful bowel movement attempt(s)/24 h (p < 0.001), anal/vaginal digitation (p = 0.005), regular enema use (p = 0.004), toilet revisiting (p = 0.004) and >10 min toileting (p = 0.004), and four reflected storage dysfunction, namely leaking flatus (p = 0.002), faecal urgency (p = 0.005), use of antidiarrhoeal medication (p = 0.001) and incontinence-related lifestyle alterations (p < 0.001). A total of 130 patients (53.5%) had 'no LARS', 56 (23.1%) had 'minor LARS' and 57 (23.4%) had 'major LARS'. Fifty-seven (44.5%) patients classified as having 'no LARS' had evacuatory dysfunction. CONCLUSION: Postoperative storage and evacuatory dysfunction symptoms have an adverse impact on patient satisfaction and HRQoL post-AR. The importance of comprehensively documenting symptoms of evacuatory dysfunction is highlighted. Further research is required to develop a patient satisfaction-weighted LARS-specific HRQoL instrument.

Functional outcomes and quality of life following open versus laparoscopic versus robot-assisted versus transanal total mesorectal excision in rectal cancer patients: a systematic review and meta-analysis.

BACKGROUND: The standard surgical treatment for rectal cancer is total mesorectal excision (TME), which may negatively affect patients' functional outcomes and quality of life (QoL). However, it is unclear how different TME techniques may impact patients' functional outcomes and QoL. This systematic review and meta-analysis evaluated functional outcomes of urinary, sexual, and fecal functioning as well as QoL after open, laparoscopic (L-TME), robot-assisted (R-TME), and transanal total mesorectal excision (TaTME). METHODS: A systematic review and meta-analysis, based on the preferred reporting items for systematic reviews and meta-analysis statement, were conducted (PROSPERO: CRD42021240851). A literature review was performed (sources: PubMed, Medline, Embase, Scopus, Web of Science, and Cochrane Library databases; end-of-search date: September 1, 2023), and a quality assessment was performed using the Methodological index for non-randomized studies. A random-effects model was used to pool the data for the meta-analyses. RESULTS: Nineteen studies were included, reporting on 2495 patients (88 open, 1171 L-TME, 995 R-TME, and 241 TaTME). Quantitative analyses comparing L-TME vs. R-TME showed no significant differences regarding urinary and sexual functioning, except for urinary function at three months post-surgery, which favoured R-TME (SMD [CI] -0 .15 [- 0.24 to - 0.06], p = 0.02; n = 401). Qualitative analyses identified most studies did not find significant differences in urinary, sexual, and fecal functioning and QoL between different techniques. CONCLUSIONS: This systematic review and meta-analysis highlight a significant gap in the literature concerning the evaluation of functional outcomes and QoL after TME for rectal cancer treatment. This study emphasizes the need for high-quality, randomized-controlled, and prospective cohort studies evaluating these outcomes. Based on the limited available evidence, this systematic review and meta-analysis suggests no significant differences in patients' urinary, sexual, and fecal functioning and their QoL across various TME techniques.

Comparison of a robotic surgery program for rectal cancer: short- and long-term results from a comparative, retrospective study between two laparoscopic and robotic reference centers.

BACKGROUND: It is assumed that robotic-assisted surgery (RAS) may facilitate complex pelvic dissection for rectal cancer compared to the laparoscopic-assisted resection (LAR). The aim of this study was to compare perioperative morbidity, short- and long-term oncologic, and functional outcomes between the RAS and LAR approaches. METHODS: Between 2015 and 2021, all rectal cancers operated on by (LAR) or (RAS) were retrospectively reviewed in two colorectal surgery centers. RESULTS: A total of 197 patients were included in the study, with 70% in the LAR group and 30% in the RAS group. The tumor location and stage were identical in both groups (not significant = NS). The overall postoperative mortality rate was not significantly different between the two groups. (0% LAR; 0.5% RAS; NS). The postoperative morbidity was similar between the two groups (60% LAR vs 57% RAS; NS). The number of early surgical re-interventions within the first 30 days was similar (10% for the LAR group and 3% for the RAS group; NS). The rate of complete TME was similar (88% for the LAR group and 94% for the RAS group; NS). However, the rate of circumferential R1 was significantly higher in the LAR group (13%) compared to the RAS group (2%) (p = 0.009). The 3-year recurrence rate did not differ between the two groups (77% for both groups; NS). After a mean follow-up of three years, the incidence of anterior resection syndrome was significantly lower in the LAR group compared to the RAS group (54 vs 76%; p = 0.030). CONCLUSIONS: The use of a RAS was found to be reliable for oncologic outcomes and morbidity. However, the expected benefits for functional outcomes were not observed. Therefore, the added value of RAS for rectal cancer needs to be reassessed in light of new laparoscopic technologies and patient management options.

Association between frailty, long-term mortality and functional outcomes for older adults undergoing emergency laparotomy.

BACKGROUND: An increasing number of older patients are undergoing emergency laparotomy (EL). Frailty is thought to contribute to adverse outcomes in this group. The best method to assess frailty and impacts on long-term mortality and other important functional outcomes for older EL patients have not been fully explored. METHODS: A prospective multicenter study of older EL patients was conducted across four hospital sites in New Zealand from August 2017 to September 2022. The Clinical Frailty Scale (CFS) was used to measure frailty-defined as a CFS of ≥5. Primary outcomes were 30-day and one-year mortality. Secondary outcomes were postoperative morbidity, admission for rehabilitation, and increased care level on discharge. A multivariate logistic regression analysis was conducted, adjusting for age, sex, and ethnicity. RESULTS: A total of 629 participants were included. Frailty prevalence was 14.6%. Frail participants demonstrated higher 30-day and 1-year mortality-20.7% and 39.1%. Following adjustment, frailty was directly associated with a significantly increased risk of short- and long-term mortality (30-day aRR 2.6, 95% CI 1.5, 4.3, p = <0.001, 1-year aRR 2.0, 95% CI 1.5, 2.8, p < 0.001). Frailty was correlated with a 2-fold increased risk of admission for rehabilitation and propensity of being discharged to an increased level of care, complications, and readmission within 30 days. CONCLUSION: Frailty was associated with increased risk of postoperative mortality up to 1-year and other functional outcomes for older patients undergoing EL. Identification of frailty in older EL patients aids in patient-centered decision-making, which may lead to improvement in outcomes.

Is a minimum duration of 5 days of unfractionated heparin infusion necessary before transition to oral anticoagulation in cerebral venous thrombosis? a retrospective chart review.

In managing cerebral venous sinus thrombosis (CVT), the standard approach has been administering parenteral anticoagulation for at least five days, despite limited supporting evidence. This study aimed to determine the optimal duration of parenteral anticoagulation for CVT patients and its potential impact on their functional outcomes upon discharge. This retrospective observational cohort study was conducted across multiple healthcare centers and included adult CVT patients who received varying durations of parenteral anticoagulation: less than 5 days (n = 25) or 5 days or more (n = 16). The primary focus was on the duration of acute anticoagulation treatment, with secondary endpoints including hospital stay length and functional outcomes. The study found that a shorter duration of anticoagulation treatment (< 5 days) was linked to more favorable outcomes, as measured by the modified Rankin Scale (mRS) (68% vs. 25%, RR = 0.37, CI 0.15-0.90, p = 0.007). However, regression analysis showed non statistically significant associations for all variables except gender. Female patients were significantly more likely to receive a shorter duration of anticoagulation (Odds Ratio: 2.6, 95% CI: 2.2-3.1, P-Value: <0.001). These findings suggest a potential connection between shorter anticoagulation duration (< 5 days) and improved CVT patient outcomes, as indicated by their mRS scores at discharge. The observed relationship between female gender and shorter anticoagulation duration warrants further exploration. Nevertheless, caution is necessary when interpreting these findings due to the small sample size and specific patient characteristics. Further research in a larger and more diverse cohort is essential to validate these results and understand their implications fully.

Effect of intravenous thrombolysis before endovascular therapy on outcomes in acute ischemic stroke with large core: a systematic review and meta-analysis.

OBJECTIVE: To investigate the effect of intravenous thrombolysis (IVT) before endovascular therapy (EVT) on outcomes in acute ischemic stroke of large core. METHODS: The studies comparing functional outcomes after EVT with and without IVT were systematically searched up to October 10th, 2023. Odds ratio (OR) was pooled using random effects model. Subgroup analysis was performed stratified by study design, country or region, study date, imaging methods and time window. RESULTS: Thirteen studies were included, enrolling 1717 patients. The pooled rate of functional independence in patients receiving IVT + EVT was 26% (95% CI 20% - 33%), significantly higher than 18% (95% CI 15% - 20%) in those receiving EVT alone (OR 1.55, 95% CI 1.13-2.12, P = 0.006; I²= 23.9%). In subgroup analysis, prior IVT increased the probability of functional independence in retrospective studies (OR 1.97, 95% 1.47-2.63, P < 0.00001; I2 = 0). Non-Asian patients benefit from IVT before EVT for functional independence (OR 2.04, 95% 1.48-2.81, P < 0.0001; I2 = 0), but Asian patients did not (OR 1.45, 95% 0.90-2.35, p = 0.13; I2 = 0). The pooled rate of symptomatic intracranial hemorrhage in patients receiving IVT + EVT was 16% (95% CI 12% - 20%), inclining to be higher than 11% (95% CI 6% - 15%) in those receiving EVT alone without significant difference (OR 1.42, 0.83-2.41, P = 0.20; I²= 12%). CONCLUSIONS: IVT before EVT might increase the probability of functional independence in non-Asian patients with large ischemic core. The results provided clinicians with additional information on selecting eligible patients for EVT.

Impact of delirium on acute stroke outcomes: A systematic review and meta-analysis.

Delirium is a common complication in acute stroke patients. A 2011 meta-analysis showed an increased risk of in-hospital mortality and mortality within 12 months post-stroke, longer hospitalization durations, and increased likelihood of being discharged to a nursing home for patients experiencing post-stroke delirium. There is a need for an updated meta-analysis with several new studies having been since published. The PubMed and Scopus databases were screened for relevant studies. Inclusion criteria were as follows: retrospective or prospective studies reporting on the effects of delirium accompanying acute stroke on mortality, functional outcomes, length of hospital stay and need for re-admission. Strength of association was presented as pooled adjusted relative risk (RR) for categorical outcomes and weighted mean difference (WMD) for continuous outcomes. Statistical analysis was done using STATA version 16.0. The meta-analysis included 22 eligible articles. Eighteen of the 22 studies were prospective follow ups. Included studies were of good quality. Post-stroke delirium was associated with increased risk of in-hospital mortality, as well as mortality within 12 months post-stroke. Patients with delirium experienced increased hospital stay durations, were at greater risk for hospital readmission, and showed elevated risk for poor functional outcome. Compared to those who did not have delirium, stroke patients with delirium were 42% less likely to be discharged to home. Acute stroke patients with delirium are at an increased risk for poor short- and long-term outcomes. More research is needed to identify the best set of interventions to manage such patients and improve outcomes.

Prediction of Changes in Functional Outcomes During the First Year After Inpatient Stroke Rehabilitation: A Longitudinal Study.

OBJECTIVE: To identify meaningful changes in patients in 3 functional domains (basic mobility [BM], daily activity [DA], and applied cognition [AC]) after discharge from inpatient stroke rehabilitation and to identify the predictors of 1-year functional improvement. DESIGN: A longitudinal, multicenter, prospective cohort study. SETTING: The acute care wards of 3 hospitals in the Greater Taipei area of Taiwan. PARTICIPANTS: Five hundred patients with stroke in acute care wards (mean age=60±12.2 years, 62% men, N=500). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE(S): The Mandarin version of the Activity Measure for Post-Acute Care (AM-PAC) short forms were assessed at discharge and 3-, 6-, and 12-month follow-up. The minimal detectable change (MDC) was used to categorize changes in the scores as improved and unimproved at the 4 time points. RESULTS: The mean scores of the AM-PAC BM and DA subscales substantially increased over the first 3 months after discharge (86% of participants exhibited improvement) and slightly increased during the subsequent 9 months (5∼26% of participants exhibited improvement). However, the mean score of the AC subscale decreased within the first 3 months and increased over the subsequent 9 months (22-23% of participants exhibited improvement). The BM, AC scores at discharge were the dominant predictors of subsequent functional improvement (P<.05). Patients with a higher functional stage at discharge were more likely to experience significant improvement. CONCLUSION: This study established the capacity of the AM-PAC to predict functional improvement in 3 domains during the early, middle, and late stages of recovery. The findings can assist clinicians in identifying patients at risk of unfavorable long-term functional recovery and providing such patients with tailored interventions during the early stage of rehabilitation.

Impact of prior spinal fusion surgery on complications and functional outcomes following total hip arthroplasty: an updated systematic review and meta-analysis.

PURPOSE: This study aimed to compare the complication rates and functional outcomes between patients with and without a history of spinal fusion undergoing THA. METHODS: A systematic search was conducted across PubMed, EMBASE, Scopus, and Cochrane databases. Studies that compared adults with and without a history of spinal fusion after primary THA were included. The methodological quality of the studies was evaluated using MINORS criteria. Meta-analyses were performed utilizing mean differences (MD), standardized mean differences (SMD), and odds ratios (OR), along with 95% confidence intervals (CI). RESULTS: Seventeen studies involving 1,789,356 patients (31,786 in the SF group and 1,757,570 in the Non-SF group) were analyzed. The spinal fusion group exhibited significantly higher rates of dislocation (OR 2.50, 95% CI 1.78-3.52), periprosthetic fracture (OR 1.96, 95% CI 1.39-2.77), overall complications (OR 1.73, 95% CI 1.10-2.71), and revision rates (OR 1.86, 95% CI 1.74-1.99). Furthermore, within the first three months, there was an increased risk of dislocation (OR 4.38, 95% CI 1.36-14.14) and revisions (OR 3.87, 95% CI 1.63-9.18). Longer spinal fusions were significantly associated with a higher risk of dislocations (OR 0.62, 95% CI 0.53-0.71). Additionally, prior spinal fusion was linked to higher levels of pain (SMD 0.11, 95% CI 0.02-0.19) and poorer functional outcomes (MD - 0.09, 95% CI - 0.18 to - 0.00). CONCLUSIONS: Patients with a history of spinal fusion undergoing THA exhibit increased complication rates, higher levels of pain, and greater functional limitations than those without prior fusion. These findings have significant clinical implications for optimizing perioperative care in high-risk patient populations.

Do the management and functional outcomes of the surgically treated spinal fractures change in suicidal jumpers?

PURPOSE: The aim of the study was to determine the effect of trauma etiology on the management, functional outcomes and psychiatric characteristics of suicide jumpers and patients who accidentally fall from height. METHODS: 89 patients (48 accidental falls and 41 suicidal jumpers) who had undergone spinal surgery were included in the study. The patients were evaluated clinically and radiologically. Visual Analog Scale (VAS), Roland Morris Disability Questionnaire (RMDQ) and McGill Pain Questionnaire (MPQ) were performed for functional evaluation. BECK hopelessness scale (BHS), BECK depression inventory (BDI), and SF-36 scales were used for the psychiatric evaluation. All outcomes were compared between suicidal jumpers and accidental falls. RESULTS: The RMDQ and ODI questionnaires stated a higher disability in the suicide jump group (p = 0.001 and p = 0.029, respectively). However, the VAS and MPQ questionnaires did not differ in significance between groups (p = 0.182 and p = 0.306, respectively). The SF-36 scale showed that physical function, role emotional, vitality and mental health subdomains were worse in the suicide jump group (p = 0.001, p = 0.029, p = 0.014 and p = 0.030, respectively). BDI scores were significantly higher in the suicide jump group while no difference was observed between the groups in terms of BSH (p = 0.017 and p = 0.940, respectively). CONCLUSION: Psychiatric disorders are more common in patients in the suicidal jumpers. The presence of underlying psychiatric problems adversely affects the postoperative functional outcomes of patients with surgically treated spinal fractures. A multidisciplinary approach together with raising awareness in this way can improve the clinical outcomes after orthopedic treatment, even if there is physical disability.

Targeted-delivery of nanomedicine-enabled methylprednisolone to injured spinal cord promotes neuroprotection and functional recovery after acute spinal cord injury in rats.

To date, no therapy has been proven to be efficacious in fully restoring neurological functions after spinal cord injury (SCI). Systemic high-dose methylprednisolone (MP) improves neurological recovery after acute SCI in both animal and human. MP therapy remains controversial due to its modest effect on functional recovery and significant adverse effects. To overcome the limitation of MP therapy, we have developed a N-(2-hydroxypropyl) methacrylamide copolymer-based MP prodrug nanomedicine (Nano-MP) that can selectively deliver MP to the SCI lesion when administered systemically in a rat model of acute SCI. Our in vivo data reveal that Nano-MP is significantly more effective than free MP in attenuating secondary injuries and neuronal apoptosis. Nano-MP is superior to free MP in improving functional recovery after acute SCI in rats. These data support Nano-MP as a promising neurotherapeutic candidate, which may provide potent neuroprotection and accelerate functional recovery with improved safety for patients with acute SCI.

A balance focused biometric does not predict rehabilitation needs and outcomes following total knee arthroplasty.

BACKGROUND: Both length of hospital stay and discharge to a skilled nursing facility are key drivers of total knee arthroplasty (TKA)-associated spending. Identifying patients who require increased postoperative care may improve expectation setting, discharge planning, and cost reduction. Balance deficits affect patients undergoing TKA and are critical to recovery. We aimed to assess whether a device that measures preoperative balance predicts patients' rehabilitation needs and outcomes after TKA. METHODS: 40 patients indicated for primary TKA were prospectively enrolled and followed for 12 months. Demographics, KOOS-JR, and PROMIS data were collected at baseline, 3-months, and 12-months. Single-leg balance and sway velocity were assessed preoperatively with a force plate (Sparta Science, Menlo Park, CA). The primary outcome was patients' discharge facility (home versus skilled nursing facility). Secondary outcomes included length of hospital stay, KOOS-JR scores, and PROMIS scores. RESULTS: The mean preoperative sway velocity for the operative leg was 5.7 ± 2.7 cm/s, which did not differ from that of the non-operative leg (5.7 ± 2.6 cm/s, p = 1.00). Five patients (13%) were discharged to a skilled nursing facility and the mean length of hospital stay was 2.8 ± 1.5 days. Sway velocity was not associated with discharge to a skilled nursing facility (odds ratio, OR = 0.82, 95% CI = 0.27-2.11, p = 0.690) or longer length of hospital stay (b = -0.03, SE = 0.10, p = 0.738). An increased sway velocity was associated with change in PROMIS items from baseline to 3 months for global07 ("How would you rate your pain on average?" b = 1.17, SE = 0.46, p = 0.015) and pain21 ("What is your level of pain right now?" b = 0.39, SE = 0.17, p = 0.025) at 3-months. CONCLUSION: Preoperative balance deficits were associated with postoperative improvements in pain and function after TKA, but a balance focused biometric that measured single-leg sway preoperatively did not predict discharge to a skilled nursing facility or length of hospital stay after TKA making their routine measurement cost-ineffective.

Improvement in Swallowing Function in Patients with Previous Irradiation for Nasopharyngeal Carcinoma by Expiratory Muscle Strength Training.

Dysphagia and chronic aspiration are common post-irradiation complications in nasopharyngeal carcinoma (NPC) survivors. Expiratory Muscle Strength Training (EMST) is a simple device-driven exercise therapy for swallowing training. This study investigates the effectiveness of EMST in a group of post-irradiated NPC patients. This prospective cohort, including twelve patients with previous irradiation for NPC and with swallowing disturbance, was performed between 2019 and 2021 in a single institution. Patients were trained with EMST for 8 weeks. Non-parametric analyses examined effects of EMST on primary outcome, maximum expiratory pressure. Secondary outcomes were measured with Penetration-aspiration scale, Yale pharyngeal residue severity rating scale (YPRSRS) by flexible endoscopic evaluation of swallowing, and Eating Assessment Tool (EAT-10) and M.D. Anderson Dysphagia Inventory questionnaire. Twelve patients, with a mean (SD) age of 64.3 (8.2) were recruited. There was no patient dropout with 88.9% overall compliance of training. Maximum expiratory pressure improved by 41% (median 94.5 to 133.5 cmH2O, p = 0.003). There was reduction in Penetration-aspiration scale with thin liquid (median 4 to 3, p = 0.026), and in YPRSRS at pyriform fossa with mildly thick liquid (p = 0.021) and at vallecula with thin liquid (p = 0.034), mildly thick liquid (p = 0.014) and pureed meat congee (p = 0.016). Questionnaire scores did not significantly change statistically. EMST is an easy-to-use and effective exercise therapy to improve airway safety and swallowing function in post-irradiated NPC survivors.
