RESUMEN

Purpose: The purpose of this study was to analyse the independent prognostic significance of perineural invasion (PNI) on local recurrence (LR) in patients with oral squamous cell carcinoma (OSCC) managed primarily with surgery. Subjects and Methods: Clinical and histopathological data of 195 patients with OSCC were analysed retrospectively to identify risk factors associated with PNI and to evaluate its significant correlation with local recurrence, overall survival (OS) and recurrence free survival (RFS). Results: Patients were followed for a mean period of 39.5 ± 1.376 months and median 35 months. PNI was found in 57 patients (29.2%). PNI correlated with tongue subsite (p = 0.001), nodal metastasis (p < 0.000), depth of invasion (DOI) (p = 0.002), stage (p = 0.013) and adjuvant therapy (p < 0.001). Mean time to recurrence with PNI was significantly shorter (p = 0.002).Multivariate analysis did not establish significant relationship between PNI and LR. Kaplan-Meier curve did not show statistical significance with OS (p = 0.085) or RFS (p = 0.110). Conclusion: PNI remains an aggressive factor for nodal metastasis mandating neck management for regional control. Though PNI showed no statistical significance with LR, time to recurrence in PNI positive patients were significantly shorter. Hence, close follow-up regimen becomes necessary.

RESUMEN

Background: The reduced mobility in critically ill patients is still a reality in many intensive care units. This study aims to investigate if mobility level is associated with extubation outcome in adult patients.Methods: Prospective cohort study which comprised adults who had undergone initial invasive mechanical ventilation for more than 24 hours and were independently mobile before hospitalization. Patient progress was monitored from ICU admission to discharge. Data were collected daily from medical records and multidisciplinary teams, considering variables such as age, sex, BMI, SAPS III score, type of ICU admission, comorbidities, sedation, usage of vasoactive drugs, neuromuscular blockers, duration of mechanical ventilation, and ICU mobility scale (IMS). The primary outcome was the success of extubation.Results: IMS values did not directly associate with extubation outcome. Older patients demonstrated a reduced tendency for high IMS values, as did those on prolonged usage of vasoactive drugs or mechanical ventilation. Patients with higher IMS values achieved successful extubation earlier, suggesting a link between mobility and faster extubation success.Conclusion: The level of mobility assessed 24 hours after extubation was not associated with extubation success. The following characteristics were associated with a lower propensity to present high IMS: older age, greater number of days of use of vasoactive drugs and mechanical ventilation. Patients with higher levels of mobility had a successful extubation event earlier in the ICU. Studies that assess mobility on a continuous basis would be more precise in identifying this association.

RESUMEN

BACKGROUND: Open surgical repair of suprarenal abdominal aortic aneurysm and type IV thoracoabdominal aortic aneurysm (TAAA) remains a surgical challenge because of the inducted intraoperative visceral and renal ischemia. We report a novel three-step technique named debranch, perfuse, reconstruct (DPR), using debranching and passive arterial shunt to decrease these ischemic complications. The main aim of this study was to evaluate the 30-day and 1-year mortality rates associated with these DPR technique. The secondary aim was to evaluate the impact on renal function and the primary patency of the repaired arteries. METHODS: This retrospective study included all consecutive patients who underwent elective surgery for SRAAA or type IV TAAA using the DPR technique between January 2011 and June 2022. In debranching, using partial side clamping, a multibranch graft was implanted side-to-end into the descending thoracic aorta. The left renal artery was anastomosed end-to-end to the graft. As needed, the superior mesenteric artery (SMA), the celiac trunk, and the right renal artery could also be anastomosed to the graft. In the perfusion step, cannulas were connected to the last branch of the multibranch graft to perfuse other arteries during aortic cross-clamping. For repair, a tube or bifurcated graft was used for the aortic repair. The branch used as a passive temporary arterial shunt was ligated at the end of the intervention. Clinical, radiological, and biological preoperative and postoperative factors were reviewed using a standardized database. Procedural complications and reinterventions were analyzed, as well as artery patency. RESULTS: There were 40 patients who underwent DPR technique. The mean patient age was 67 ± 13 years and two were women. Twenty-three patients presented with a SRAAA and 17 with a type IV TAAA. The 30-day and 1-year mortality rates were 2.5% (one patient). Two respiratory complications (5%) and three mesenteric ischemic complications (7%) have been recorded. No patient developed signs of cardiac or spinal cord dysfunction. We did not observe a significant change in postoperative renal function. The celiac trunk, superior mesenteric artery, left renal artery, and right renal artery bypass patency rates at 1 year were 95%, 100%, 90%, and 100%, respectively. CONCLUSIONS: The SRAAA and type IV TAAA repair with DPR technique provides short visceral and renal ischemia times with a low mortality rate. This technique could be an option to consider for visceral and renal protection during open surgical repair.

RESUMEN

Speckle-tracking echocardiography (STE) parameters are an integral part of the assessment of left ventricular (LV) function. We aimed to evaluate established and novel STE parameters of LV diastolic function and their prognostic role in patients with LV anteroapical aneurysm undergoing surgical ventricular repair (SVR). We retrospectively examined the data of 137 patients with anteroapical LV aneurysm who underwent SVR. In 27 patients, the correlation of STE parameters with invasive hemodynamic parameters was evaluated. Preoperative echocardiographic parameters were assessed for their association with outcome, defined as all-cause mortality, LV assist device implantation, or heart transplantation. The late diastolic strain rate (GLSRa) showed a stronger correlation with mean pulmonary artery pressure (r = - 0.75, p < 0.001) than all other parameters. GLSRa was also significantly correlated with mean pulmonary capillary wedge pressure and LV end-diastolic pressure. In the multivariate model, GLSRa and the ratio of early diastolic filling velocity to GLSRa demonstrated incremental prognostic value in addition to clinical and echocardiographic parameters. Patients with GLSRa < 0.59 s-1 had significantly shorter event-free survival than those with GLSRa > 0.59 s-1 (6.7 vs. 10.9 years, p < 0.001). Peak reservoir left atrial strain showed a weaker association with hemodynamic parameters and outcome compared to GLSRa. In patients with LV aneurysm, late diastolic strain rate and left atrial strain can be used for the assessment of LV diastolic function and have a predictive value for the outcome after surgical ventricular restoration.

RESUMEN

BACKGROUND: The literature is replete with favorable face-lift results, yet the objective facial rejuvenation outcome measures in Chinese women have remained poorly understood. OBJECTIVE: The purpose of the study is to objectively evaluate the apparent age (AA) reduction in Chinese women following face-lift by artificial intelligence (AI) and objective observers. METHODS: Standardized pre- and postoperative (1-year) images of 48 patients undergoing face-lift procedures were analyzed by AI to estimate AA. Additionally, 10 blinded, naive observers viewed each patient's images and assessed AA. The accuracy of AA and reduction in AA were evaluated and compared between the two methods. FACE-Q surveys were employed to measure patient-reported facial esthetic outcomes. RESULTS: The AI demonstrated higher precision than the observers in age estimation, with a mean absolute error of 3.34 years and 90% Pearson correlation. AA reduction generated by AI was significantly lower than that by observers, with a mean reduction of 3.75 ± 3.93 and 4.51 ± 1.20, respectively (p < 0.05). However, both methods showed less AA reduction than patient self-appraisal (- 7.3 years). Improvements in facial rejuvenation following face-lift surgery is relevant to the patient's preoperative aging status. Patients whose pre-AA was greater than chronological age (CA) became "back to normal," while those whose pre-AA was less than CA became "turning back the clock." CONCLUSION: The utilization of AI could provide objective, evidence-based data in the field of face-lift surgery. As a simple, complete, and time-sparing method, AI is expected to be routinely used in clinical trials and practice.

RESUMEN

BACKGROUND: International health policies and researchers have emphasized the value of evaluating patient-reported outcomes (PROs) in clinical studies. However, the characteristics of PROs in adult tumor clinical trials in China remain insufficiently elucidated. OBJECTIVE: This study aims to assess the application and characteristics of PRO instruments as primary or secondary outcomes in adult randomized clinical trials related to tumors in China. METHODS: This cross-sectional study identified tumor-focused randomized clinical trials conducted in China between January 1, 2010, and June 30, 2022. The ClinicalTrials.gov database and the Chinese Clinical Trial Registry were selected as the databases. Trials were classified into four groups based on the use of PRO instruments: (1) trials listing PRO instruments as primary outcomes, (2) trials listing PRO instruments as secondary outcomes, (3) trials listing PRO instruments as coprimary outcomes, and (4) trials without any mention of PRO instruments. Pertinent data, including study phase, settings, geographic regions, centers, participant demographics (age and sex), funding sources, intervention types, target diseases, and the names of PRO instruments, were extracted from these trials. The target diseases involved in the trials were grouped according to the American Joint Committee on Cancer Staging Manual, 8th Edition. RESULTS: Among the 6445 trials examined, 2390 (37.08%) incorporated PRO instruments as part of their outcomes. Within this subset, 26.82% (641/2390) listed PRO instruments as primary outcomes, 52.72% (1260/2390) as secondary outcomes, and 20.46% (489/2390) as coprimary outcomes. Among the 2,155,306 participants included in these trials, PRO instruments were used to collect data from 613,648 (28.47%) patients as primary or secondary outcomes and from 74,287 (3.45%) patients as coprimary outcomes. The most common conditions explicitly using specified PRO instruments included thorax tumors (217/1280, 16.95%), breast tumors (176/1280, 13.75%), and lower gastrointestinal tract tumors (173/1280, 13.52%). Frequently used PRO instruments included the European Organisation for Research and Treatment of Cancer Quality of Life Core Questionnaire-30, the visual analog scale, the numeric rating scale, the Traditional Chinese Medicine Symptom Scale, and the Pittsburgh Sleep Quality Index. CONCLUSIONS: Over recent years, the incorporation of PROs has demonstrated an upward trajectory in adult randomized clinical trials on tumors in China. Nonetheless, the infrequent measurement of the patient's voice remains noteworthy. Disease-specific PRO instruments should be more effectively incorporated into various tumor disease categories in clinical trials, and there is room for improvement in the inclusion of PRO instruments as clinical trial end points.

RESUMEN

Background: While most studies assessing psychotherapy efficacy are randomized-controlled trials conducted in research institutions or short clinical treatments, the understanding of psychotherapy effectiveness under regular, clinically representative conditions, particularly in outpatient practice, remains limited. Representative data examining the effectiveness of psychotherapy under real-world conditions in Austria is lacking. Aims and Methods: This paper introduces a naturalistic observational combined process- and outcome study, implementing a dual-perspective approach through standardised pre- and post-treatment questionnaires and evaluating changes in the therapeutic alliance after each session. Further, semi-structured qualitative interviews aim to illuminate the personal experiences of patients and therapists. The primary objective of the presented study is to discern whether symptoms markedly decrease following therapy. A significant secondary goal is to trace the therapeutic alliance's evolution from both patient and therapist viewpoints, emphasising the alliance-outcome association and gender dynamics within the pairs. This paper discusses the project's feasibility after three years and shares key insights. Discussion: Recruitment for this study has posed substantial challenges due to psychotherapists' concerns regarding data protection, extensive documentation, and philosophical reservations about the study design. Consequently, we recruited fewer participants than initially planned. Despite these hurdles, qualitative data collection has shown notable success. Given psychotherapists' busy schedules and reluctance to participate, more potent external incentives or a legal obligation may be necessary to encourage participation in future studies.

RESUMEN

Our aim was to investigate which features were associated with clinical successes at short- and mid-terms following prostate artery embolization (PAE) for symptomatic benign prostate hypertrophy (BPH). All adults treated by PAE for BPH at our referral center between January 2017 and March 2021, with pre-treatment MRI, technical success, and follow-up at 3 months and 2 years were included in this single-center retrospective study. Radiologists reviewed the prostatic protrusion index (PPI), adenomatous dominant BPH (adBPH), and Wasserman classification on pre-treatment MRI. Radiomics analysis was achieved on the transitional zone on pre-treatment T2-weighted imaging (WI) and ADC, and comprised reproducibility assessment, unsupervised classifications, and supervised radiomics scores obtained with cross-validated Elasticnet regressions. Eighty-eight patients were included (median age: 65 years), with 81.8% clinical successes at 3 months and 60.2% at 2 years. No feature was associated with success at 3 months, except the radiomics score trained on T2-WI and ADC (AUROC = 0.694). Regarding success at 2 years, no radiomics approaches provided significant performances; however, Wasserman type-1 and change in international prostate symptom score (IPSS) at 3 months ≤ -35% were associated with success in multivariable analysis (OR = 5.82, p = 0.0296, and OR = 9.04, p = 0.0002). Thus, while radiomics provided limited interest, Wasserman classification and early IPSS changes appeared predictive of mid-term outcomes.

RESUMEN

BACKGROUND: Despite intensive research on preventing and treating vasospasm and delayed cerebral ischemia in aneurysmal subarachnoid hemorrhage (aSAH), mortality and morbidity rates remain high. Early brain injury (EBI) has emerged as possibly the major significant factor in aSAH pathophysiology, emphasizing the need to investigate EBI-associated clinical events for improved patient management and decision-making. This study aimed to identify early clinical and radiological events within 72 h after aSAH to develop a conclusive predictive EBI score for clinical practice. METHODS: This retrospective analysis included 561 consecutive patients with aSAH admitted to our neurovascular center between 01/2014 and 09/2022. Fourteen potential predictors occurring within the initial 72 h after hemorrhage were analyzed. The modified Rankin Scale (mRS) score at 6 months, discretized to three levels (0-2, favorable; 3-5, poor; 6, dead), was used as the outcome variable. Univariate ordinal regression ranked predictors by significance, and forward selection with McFadden's pseudo-R2 determined the optimal set of predictors for multivariate proportional odds logistic regression. Collinear parameters were excluded, and fivefold cross-validation was used to avoid overfitting. RESULTS: The analysis resulted in the Subarachnoid Hemorrhage Associated Early Brain Injury Outcome Prediction score (SHELTER-score), comprising seven clinical and radiological events: age (0-4 points), World Federation of Neurosurgical Societies (0-2.5 points), cardiopulmonary resuscitation (CPR) (2 points), mydriasis (1-2 points), midline shift (0.5-1 points), early deterioration (1 point), and early ischemic lesion (2 points). McFadden's pseudo-R2 = 0.339, area under the curve for death or disability 0.899 and 0.877 for death. A SHELTER-score below 5 indicated a favorable outcome (mRS 0-2), 5-6.5 predicted a poor outcome (mRS 3-5), and ≥ 7 correlated with death (mRS 6) at 6 months. CONCLUSIONS: The novel SHELTER-score, incorporating seven clinical and radiological features of EBI, demonstrated strong predictive performance in determining clinical outcomes. This scoring system serves as a valuable tool for neurointensivists to identify patients with poor outcomes and guide treatment decisions, reflecting the great impact of EBI on the overall outcome of patients with aSAH.

RESUMEN

BACKGROUND: The paranasal depression is a common facial feature of Oriental populations. One of the most wildly used method to improve it was paranasal augmentation using expanded polytetrafluoroethylene (ePTFE). The effectiveness of it should be tested by three-dimensional morphological measurements. METHODS: Patients who underwent paranasal augmentation using ePTFE between January 2017 and December 2022 were recruited in the study. The preoperative and postoperative clinical variables and three-dimensional measurement of patients were also collected. The satisfaction outcome were assessed. RESULTS: By establishing a coordinate system based on the Frankfurt plane, 16 landmarks including nasal alar crest, subnasal point, upper lip, pogonion, glabella, sub-cheek, orbitale, tragion in left and right side of faces were marked. Five segments, 4 ratios, and 3 angles were measured based on it. The significant increase of segments, ratios, and angles indicated that paranasal augmentation could increase the protrusion of paranasal area, both in absolute value and relative proportion. The significant decrease of other data indicated that the protrusion difference between paranasal base and upper lip, forehead, and chin, respectively, were shortened after surgery. The average size of implant was 6.54 ± 1.02 mm, and the average increase of paranasal height was 4.38 ± 1.04 mm postoperatively. This indicates that two-thirds of its height will ultimately be reflected effectively in the sagittal elevation of the paranasal base. CONCLUSIONS: Paranasal augmentation using ePTFE could effectively increase paranasal height and improve subunits relationships, and the ePTFE prosthesis should be designed and carve considering the 1/3 loss of height after implantation.

RESUMEN

OBJECTIVES: This study examines the effectiveness and efficiency of intensive psychodynamic psychotherapy for severely impaired patients. METHOD: 104 patients in four public mental health centers underwent intensive psychodynamic psychotherapy. The number and duration of psychiatric hospitalizations were monitored for these patients from one year before therapy to eight years after. Several outcome variables were measured every six months, six times in total over two and a half years, using a longitudinal design. A multi-level analytic approach was applied to account for repeated measurements and missing data. RESULTS: Significant improvement was found in all three symptomatic outcome measures (SCL-90, OQ-45, BDI) throughout treatment. The numbers of psychiatric hospitalizations and psychiatric hospitalization days decreased significantly from the level they were in the year before the start of psychodynamic treatment to three years after the start of treatment. These results were maintained for at least up to eight years. After capitalization, the overall cumulative 127.47-day decrease in hospitalization days equals savings of 115,850 NIS. The average cost of treatment after capitalization was 26,770 NIS. The insurer's estimated direct savings is 89,080 NIS (24,054 $). CONCLUSION: These findings support the hypothesis that psychodynamic psychotherapy is clinically effective and economically efficient for severely impaired patients.

RESUMEN

BACKGROUND AND AIMS: This study explored the association between urinary liver-type fatty acid-binding protein to creatinine (uL-FABP-cre) ratio and postoperative clinical failure in unilateral primary aldosteronism (PA) patients undergoing adrenalectomy. MATERIALS AND METHODS: Data from the Taiwan Primary Aldosteronism Investigation Group database were analyzed, including patients with unilateral PA who had adrenalectomy between December 2015 and October 2018. Statistical methods included generalized additive modeling, logistic regression analysis, net reclassification improvement (NRI), and the C statistic. RESULTS: In the study cohort of 131 patients (mean age 52.3 ± 10.8 years; 43.5% male), 117 achieved clinical success, while 14 experienced clinical failure. A uL-FABP-cre ratio ≥5 predicted clinical failure (odds ratio: 6.22, p = 0.005). Subgroup analysis revealed its efficacy in predicting clinical failure in patients with BMI ≥ 24 kg/m2, normokalemia, or <5 years of hypertension. Furthermore, incorporating uL-FABP-cre ratio into the Primary Aldosteronism Surgical Outcome (PASO) score significantly improved predictive ability. The addition increased the C statistic from 0.671 to 0.762 (p < 0.01) and improved category-free NRI by 0.675 (p = 0.014). CONCLUSION: A uL-FABP-cre ratio ≥5 accurately predicted clinical failure post-adrenalectomy in unilateral PA, enhancing PASO score's identification of high-risk patients for postoperative clinical failure.

RESUMEN

Health outcomes, such as body mass index and cholesterol levels, are known to be dependent on age and exhibit varying effects with their associated risk factors. In this paper, we propose a novel framework for dynamic modeling of the associations between health outcomes and risk factors using varying-coefficients (VC) regional quantile regression via K-nearest neighbors (KNN) fused Lasso, which captures the time-varying effects of age. The proposed method has strong theoretical properties, including a tight estimation error bound and the ability to detect exact clustered patterns under certain regularity conditions. To efficiently solve the resulting optimization problem, we develop an alternating direction method of multipliers (ADMM) algorithm. Our empirical results demonstrate the efficacy of the proposed method in capturing the complex age-dependent associations between health outcomes and their risk factors.

RESUMEN

OBJECTIVE: To evaluate fetomaternal outcomes in women who are normoglycemic by Diabetes in Pregnancy Study Group India (DIPSI) but have gestational diabetes mellitus (GDM) by WHO criteria versus those who are normoglycemic by both DIPSI and WHO criteria. METHODS: This was a prospective, cohort study. A total of 635 women participated. They underwent a 2-h non-fasting oral glucose tolerance test (OGTT) and results were interpreted by DIPSI. Out of 635 women, 52 were lost to follow up and 33 were diagnosed as GDM by DIPSI and excluded from the study. The remaining 550 women, after 72 h from the first test, underwent a 75-g fasting-OGTT and results were interpreted using WHO 2013 criteria. Results of the second test were blinded till delivery. The 550 women were followed for fetomaternal outcomes. Participants with normal DIPSI and normal WHO 2013 OGTT were labeled group 1. Participants with normal DIPSI but abnormal WHO 2013 OGTT were labeled group 2. Fetomaternal outcomes were compared between these groups. RESULTS: Occurrence of GDM by DIPSI was 5.1%, by WHO 2013 criteria it was 10.5%. Composite fetomaternal outcomes occurred more commonly in women with a normal DIPSI but an abnormal WHO 2013 test. Out of 550 women, 492 had normal DIPSI and normal WHO 2013 test. Out of this 492, 116 (23.6%) women had adverse fetomaternal outcomes. Fifty-eight women out of 550 had a normal DIPSI but an abnormal WHO 2013 test. Thirty-seven (63.8%) women out of 58 had adverse fetomaternal outcomes. We found statistically significant association between adverse fetomaternal outcome and GDM by WHO 2013 test (with normal DIPSI test). CONCLUSION: WHO 2013 has superior diagnostic value compared with DIPSI criteria for diagnosis of GDM.

RESUMEN

PURPOSE: This study aims to compare results after open lunate excision alone and in combination with palmaris longus tendon ball arthroplasty for the treatment of late-staged Kienböck's disease (KD). METHODS: This is a retrospective study using the prospectively collected data, and patients who had a discharge diagnosis of KD (stage IIIB based on Lichtman staging criteria) and underwent surgical treatment by lunate excision alone or in combination with palmaris longus tendon ball arthroplasty between January 2011 and December 2020 were included in this study. Variables of interest involved demographics, disease condition, operative procedure, and the outcomes evaluated at the last follow-up. Within and between comparisons were performed. RESULTS: Thirty-five patients underwent lunate excision alone, and 40 patients underwent the combination procedure. At the final follow-up, patients in both groups exhibited significant improvements compared to pre-operation, such as wrist flexion, wrist extension, carpal height ratio, PRWE score, Cooney score, and grip strength (all P < 0.05). Compared to the excision group, combination procedure group had significantly longer surgical time (P < 0.001), more blood loss (P < 0.001) and exhibited better wrist flexion (P = 0.001), PRWE score (P = 0.001), Cooney score (P = 0.0034), and grip strength (P = 0.017). The excellent or good rate based on Cooney wrist score was not significantly different (87.5% vs 71.4%, P = 0.083). CONCLUSION: Lunate excision in combination with palmaris longus tendon ball arthroplasty is a better option than lunate excision alone for the treatment of stage III KD and can be considered as an operative option.

RESUMEN

BACKGROUND: To determine the association between self-rated health (SRH) and subsequent all-cause hospitalizations in patients with bipolar disorder (BD) or major depression (MDD). METHODS: We conducted a prospective cohort study on people with BD or MDD in the UK from 2006 to 2010 using UK Biobank touchscreen questionnaire data and linked administrative health databases. The association between SRH and 2-year all-cause hospitalizations was assessed using proportional hazard regression after adjustment for sociodemographics, lifestyle behaviors, previous hospitalization use, the Elixhauser comorbidity index, and environmental factors. RESULTS: A total of 29,966 participants were identified, experiencing 10,279 hospitalization events. Among the cohort, the average age was 55.88 (SD 8.01) years, 64.02 % were female, and 3029 (10.11 %), 15,972 (53.30 %), 8313 (27.74 %), and 2652 (8.85 %) reported excellent, good, fair, and poor SRH, respectively. Among patients reporting poor SRH, 54.19 % had a hospitalization event within 2 years compared with 22.65 % for those having excellent SRH. In the adjusted analysis, patients with good, fair, and poor SRH had 1.31 (95 % CI 1.21-1.42), 1.82 (95 % CI 1.68-1.98), and 2.45 (95 % CI 2.22, 2.70) higher hazards of hospitalization, respectively, than those with excellent SRH. LIMITATIONS: Selection bias can exist as our cohort cannot fully represent all the BD and MDD cases in the UK. Moreover, the causality is questionable. CONCLUSION: SRH was independently associated with subsequent all-cause hospitalizations in patients with BD or MDD. This large study underscores the need for proactive SRH screening in this population, which might inform resource allocation in clinical care and enhance high-risk population detection.

RESUMEN

BACKGROUND: A severely contracted nose is a common occurrence. Intraoperative expansion is not sufficient to soften the severely constricted nasal envelope, which poses challenges in revision rhinoplasty. In recent years, adjuvant therapies, including nasal fat grafting and cell component injection, are applied before revision rhinoplasty to soften the nasal envelope. Herein, autologous shuffling lipo-aspirated fat and manual mechanical stretch were combined as adjuvant therapy before revision rhinoplasty. METHODS: A total of 24 patients with severe nasal contracture were included in this study. Of these, 8 received autologous shuffling lipo-aspirated fat and manual mechanical stretch before revision rhinoplasty (comprehensive therapy), 8 underwent mechanical stretch and revision rhinoplasty, and 8 patients underwent only revision rhinoplasty. The objective and subjective outcome assessment was processed in the follow-up period of 6 months. Nasal length, nasal tip projection, nasofrontal angle, and nasolabial angle were measured, and potential complications were assessed. RESULTS: All 24 patients underwent a successful revision rhinoplasty. In the comprehensive therapy group, no patient had postoperative wound infection and defect of the nasal column mucous. The comprehensive treatment group had the most significant improvement in nasal length and nasal tip projection, and the nasolabial angle was the closest to 90°, which indicated the most effective nasal revision and aesthetic contour. CONCLUSIONS: The adjuvant therapy combines autologous shuffling lipo-aspirated fat and manual mechanical stretch before revision rhinoplasty could effectively improve the surgical outcome and decrease the postoperative complications regarding severe nasal contractures.

RESUMEN

OBJECTIVE: Histrionic personality disorder (HPD) with a lifetime prevalence rate of 1.8% is an under-researched psychiatric diagnosis. The present study therefore aimed to investigate both the processes and outcomes of psychotherapy for HPD in a non-controlled study. METHODS: A total of 159 patients diagnosed with HPD were recruited and received clarification-oriented psychotherapy. Sessions 15, 20, and 25 were video-recorded and analysed using the Process-Content-Relationship Scale. Therapy outcome was assessed with symptom measures at intake and discharge. Hierarchical linear modelling was applied to estimate the changes in the psychotherapeutic outcome and associations with patient and therapist process developments. RESULTS: Improvements in relationship processes of patients and therapists were systematically related to outcome while only partial relationships were found on the levels of process and content. CONCLUSION: The present study represents the first systematic insight into core changes in patients with HPD undergoing psychotherapy.

RESUMEN

BACKGROUND: Outcomes data of intramedullary nail fixation (IMN) constructs for complex Schatzker VI tibial plateau fractures are scant in the literature. This study compares the clinical and radiographic outcomes of IMN, dual plate, and single plate constructs for Schatzker IV tibial plateau fractures. METHODS: Retrospective cohort study of sixty-two patients at a University-based Level 1 trauma center who underwent open reduction internal fixation for Schatzker VI tibial plateau fracture. Constructs evaluated were IMN (with or without raft screws), dual plating, and single plating. Demographic, clinical, and radiographic outcomes were recorded. All fractures were additionally classified based on the OTA classification for sub analyses. Mean follow-up was 13.2 (SD 13.3) months. Predictors of construct selection and outcomes were evaluated with bivariate logistic regression. Outcomes were compared between groups with independent samples t-tests and Chi Square tests. RESULTS: No significant demographic differences were found between IMN, dual plate or single plate construct cohorts. There was a higher proportion of open fractures within the IMN construct group versus the dual plate cohort (21.1% vs 3.6%). No statistically significant differences in radiographic outcomes were observed between cohort groups except for small but statistically significant differences in condylar width (CW) ratio change and tibial slope; when fracture cohorts were sub analyzed by specific OTA classification, there were no significant differences in any radiographic outcomes. There was a significant difference between the ratio of OTA 41C1, C2 and C3 fractures regarding treatment allocation (p = 0.004), favoring dual plate fixation for OTA 41C3 fractures. There were no significant differences found between treatment cohorts in terms of all cause complications (p > 0.05). IMN and single plate constructs were utilized when posteromedial condyle fractures were nondisplaced or minimally displaced. CONCLUSION: Intramedullary nail fixation with or without supplemental raft screws produced similar short-term clinical and radiographic results compared to dual and single plate constructs among patients with Schatzker VI fracture types, regardless of OTA classification. Level of Evidence Level III retrospective cohort.

RESUMEN

This clinical practice review describes the biological, biomechanical and behavioral rationale behind a return to sport bridge program used predominantly with non-elite, youth and adolescent high school and college athletes following anterior cruciate ligament (ACL) reconstruction. Post-physiotherapy, this program has produced outcomes that meet or exceed previous reports. With consideration for athletic identity and the Specific Adaptations to Imposed Demands (SAID) principle, the early program focus was on restoring non-impaired bilateral lower extremity joint mobility and bi-articular musculotendinous extensibility. Building on this foundation, movement training education, fundamental bilateral lower extremity strength and power, and motor learning was emphasized with use of external focus cues and ecological dynamics-social cognition considerations. Plyometric and agility tasks were integrated to enhance fast twitch muscle fiber recruitment, anaerobic metabolic energy system function, and fatigue resistance. The ultimate goal was to achieve the lower extremity neuromuscular control and activation responsiveness needed for bilateral dynamic knee joint stability. The rationale and conceptual basis of selected movement tasks and general philosophy of care concepts are described and discussed in detail. Based on the previously reported efficacy of this movement-based therapeutic exercise program we recommend that supplemental programs such as this become standard practice following release from post-surgical physiotherapy and before return to sports decision-making.
