Effects of Implementing a Self-Care Program for Adults With Lower Limb Prostheses.

An artificial replacement for a lost limb or portion of a limb, known as a prosthesis, is a tool that can assist a person to regain their independence. The aim of this project was to evaluate the effect of a self-care program for adults with lower limb prostheses. We used a quasi-experimental research design. We conducted our study at the Physical Medicine and Rehabilitation and Rheumatology Center affiliated with the Armed Forces, located in the Al-Geza Governorate of Egypt using a purposeful sample of 81 adults with lower limb prostheses. We used two tools for data collection: a structured interviewing questionnaire and the Trinity Amputation and Prosthesis Experience Scales (TAPES). The mean age of adults with lower limb prosthesis in our study was 38.91 years (10.53). A total of 64.2% of the study participants (n = 51) were men. We found that before the self-care program, 22.2% of the participants (n = 18) had a satisfactory level of knowledge about self-care, which increased to 88.9% (n = 72) after the program. Before the self-care program, the number of participants with adequate practice levels was 13.6% (n = 11), which increased to 100.0% (n = 81) after the program. We concluded that implementing the self-care program provided a significant improvement in the attendee's total satisfactory knowledge (χ2[79,81] = 72.90, p < .000) and adequate practice levels (p < .001).

Neural interfacing architecture enables enhanced motor control and residual limb functionality postamputation.

Despite advancements in prosthetic technologies, patients with amputation today suffer great diminution in mobility and quality of life. We have developed a modified below-knee amputation (BKA) procedure that incorporates agonist-antagonist myoneural interfaces (AMIs), which surgically preserve and couple agonist-antagonist muscle pairs for the subtalar and ankle joints. AMIs are designed to restore physiological neuromuscular dynamics, enable bidirectional neural signaling, and offer greater neuroprosthetic controllability compared to traditional amputation techniques. In this prospective, nonrandomized, unmasked study design, 15 subjects with AMI below-knee amputation (AB) were matched with 7 subjects who underwent a traditional below-knee amputation (TB). AB subjects demonstrated significantly greater control of their residual limb musculature, production of more differentiable efferent control signals, and greater precision of movement compared to TB subjects (P < 0.008). This may be due to the presence of greater proprioceptive inputs facilitated by the significantly higher fascicle strains resulting from coordinated muscle excursion in AB subjects (P < 0.05). AB subjects reported significantly greater phantom range of motion postamputation (AB: 12.47 ± 2.41, TB: 10.14 ± 1.45 degrees) when compared to TB subjects (P < 0.05). Furthermore, AB subjects also reported less pain (12.25 ± 5.37) than TB subjects (17.29 ± 10.22) and a significant reduction when compared to their preoperative baseline (P < 0.05). Compared with traditional amputation, the construction of AMIs during amputation confers the benefits of enhanced physiological neuromuscular dynamics, proprioception, and phantom limb perception. Subjects' activation of the AMIs produces more differentiable electromyography (EMG) for myoelectric prosthesis control and demonstrates more positive clinical outcomes.

Inpatient Cardiac Rehabilitation of LVAD Patients-Updated Recommendations from the Working Group of the German Society for Prevention and Rehabilitation of Cardiovascular Diseases.

Cardiac rehabilitation physicians are faced to an increasing number of heart failure patients supported by left ventricular assist devices (LVAD). Many of these patients have complex medical issues and prolonged hospitalizations and therefore need special cardiac rehabilitation strategies including psychological, social, and educational support which are actually poorly implemented.Cardiac rehabilitation with clear guidance and more evidence should be considered as an essential component of the patient care plan especially regarding the increasing number of destination patients and their long-term follow-up.In this article the working group for postimplant treatment and rehabilitation of LVAD patients of the German Society for Prevention and Rehabilitation of Cardiovascular Diseases has summarized and updated the recommendations for the cardiac rehabilitation of LVAD patients considering the latest literature.

Efficacy of silicone soft reliner on the obturator prosthesis after maxillectomy for oral malignant tumors: A single-arm prospective interventional study.

BACKGROUND: There is insufficient evidence for the efficacy of silicone soft reliner on the obturator prosthesis after maxillectomy for oral malignant tumors. OBJECTIVE: To verify the efficacy of silicone soft reliner on the obturator prosthesis after maxillectomy, by evaluating masticatory performance and quality of life (QoL). METHODS: This was a single-arm prospective interventional study, verifying the efficacy of silicone soft reliner (GC RELINE II®) on the maxillary obturator prosthesis. Data were obtained from a comparison of the endpoints after 14 days of continuous use of acrylic and silicone soft-lined prostheses. The primary endpoint was masticatory performance. The secondary endpoints were occlusal performance and oral health-related QoL (OHRQoL). The masticatory performance, occlusal performance, and OHRQoL were assessed by glucose concentration, maximum bite force, and the Japanese version of Oral Health Impact Profile (OHIP-J49), respectively. RESULTS: This study included five patients (two males, three females), aged between 71 and 88 years, with a median of 74 years. The median of glucose concentration indicated a statistically significant improvement between the acrylic resin (99.6 mg/dL) and silicone soft reliner (126.0 mg/dL) obturator prosthesis (p = .043). There was no significant difference in the median of maximum bite force between the acrylic resin (302.0 N) and silicone soft reliner (250.0 N) obturator prosthesis (p = .893). Functional limitations domain of the OHIP-J49 indicated a statistically significant improvement between the acrylic resin and silicone soft reliner obturator prosthesis (p = .043). CONCLUSIONS: This study indicated that an obturator relined with soft silicone improved masticatory performance and the OHRQoL post-maxillectomy.

Novel protective penile collar following inflatable penile prosthesis placement: The "Wang Collar".

Penile rehabilitation after inflatable penile prosthesis (IPP) implantation for the treatment of erectile dysfunction includes leaving the device partially inflated so as to preserve the penile length and to maintain hemostasis. With a partially inflated device, the penis becomes more sensitive and more susceptible to unintended insults during the immediate postoperative management. The "Wang Collar," a device intended to protect the penis in the early postoperative period, is hereby described. Three hundred and forty-eight patients had the "Wang Collar" included as part of their post-IPP management from August 2014 to February 2019. The protective collar, devised from a polystyrene cup with the bottom removed, is secured with a tape over the previously dressed and partially inflated penis. In order to evaluate the effectiveness of this device, we conducted surveys on the perioperative staff at three different institutions. The "Wang Collar" has been found to be beneficial in the early postoperative care of patients. Based on the answers to our questionnaire, the perioperative personnel found this device to be highly protective, especially when transporting the patient after IPP surgery, easy to work with, and almost never bothersome or irritative to the patient. We present a novel penile device after IPP placement, which we have found to improve patient satisfaction in the postoperative period. In addition, it eases the care of the patient by the perioperative staff. It is now our routine to use this device after IPP surgery. Further research is necessary to evaluate whether this device can decrease postoperative wound complications.

Patellar tendon morphology in trans-tibial amputees utilizing a prosthesis with a patellar-tendon-bearing feature.

A patellar-tendon-bearing (PTB) bar is a common design feature used in the socket of trans-tibial prostheses to place load on the pressure-tolerant tissue. As the patellar tendon in the residual limb is subjected to the perpendicular compressive force not commonly experienced in normal tendons, it is possible for tendon degeneration to occur over time. The purpose of this study was to compare patellar tendon morphology and neovascularity between the residual and intact limbs in trans-tibial amputees and healthy controls. Fifteen unilateral trans-tibial amputees who utilized a prosthesis with a PTB feature and 15 age- and sex- matched controls participated. Sonography was performed at the proximal, mid-, and distal portions of each patellar tendon. One-way ANOVAs were conducted to compare thickness and collagen fiber organization and a chi-square analysis was used to compare the presence of neovascularity between the three tendon groups. Compared to healthy controls, both tendons in the amputees exhibited increased thickness at the mid- and distal portions and a higher degree of collagen fiber disorganization. Furthermore, neovascularity was more common in the tendon of the residual limb. Our results suggest that the use of a prosthesis with a PTB feature contributes to morphological changes in bilateral patellar tendons.

Assessment of Physical Performance and Early Treatment Outcomes after Implantation of Modular Prostheses of Femoral and Tibial Shaft.

BACKGROUND: Tumours of bone diaphyses often require resection followed by bone reconstruction. The use of modular pro-sthe-ses permits early limb loading and rapid improvement in physical performance. The aim of this study was to evaluate the func-tioning of patients and early treatment outcomes after the implantation of modular prostheses. The analysis covered the correlation between the extent of resection, physical performance and the number of perioperative complications. MATERIAL AND METHODS: 10 patients (5 women and 5 men) with diaphyseal tumours who had modular prostheses implanted were treated at the Orthopaedic Oncology Department in Brzozów between 2014 and 2018. The mean age of the patients was 51.1 years (range: 26-63 years). Functional outcomes were assessed using the MSTS and the Karnofsky scoring system. A VAS was used to evaluate pain intensity. the extent of resection was also analysed, considering bone length and tumour weight. RESULTS: The mean tumour weight was 374g (150-700g). The length of the implants varied from 10 to 25 cm. The mean dura-tion of hospitalisation was 16 days (14-19 days). At 3 months following the surgery, the intensity of pain had decreased from a mean of 6.8 points to 4.2 points (a decrease of 26% from the pre-operative baseline). The MSTS showed improvement of functional performance from a mean of 10.8 points (36%) to 22.9 points (76%). The Karnofsky scores demonstrated an increase in physical performance from 47 to 67 points (20 points on average). Superficial infection of the wound developed in 1 patient. CONCLUSIONS: 1. The treatment of diaphyseal tumours with modular prostheses produces good functional outcomes. 2. The extent of the resection and the size of the implant have an effect on the post-operative physical performance of the patients. 3. Pre-operative evaluation of the weight of the tumour may be helpful in predicting the patient's post-operative functional status. 4. Phy-sical perfor-mance is better after the resection of femoral vs tibial tumours.

Consideraciones bioéticas sobre la competencia asistencial para la rehabilitación implantoprotésica en el adulto mayor / Bioethical considerations on the assistance competence for the prosthesis implant rehabilitation in the elderly

Las investigaciones científicas y el desarrollo social han proporcionado una mirada nueva para enfocar la vida y, junto a ello, los criterios novedosos y necesarios en el campo de la ética, especialmente en todas las disciplinas de las ciencias médicas. A tales efectos, en el presente artículo se exponen algunos aspectos relacionados con los principios de la bioética en Estomatología, con el objetivo de analizar los factores objetivos y subjetivos para la rehabilitación implantoprotésica en el adulto mayor, teniendo en cuenta que la mayoría de las veces los resultados no son satisfactorios, influenciado por factores subjetivos.

To such effects, some aspects related to the principles of bioethics in Stomatology are exposed in this work, with the aim of analyzing the objective and subjective factors for the prosthesis implant rehabilitation in the elderly, keeping in mind that most of the times the results are not satisfactory, influenced by subjective factors

A Patient with GOLD Stage 3 COPD « cured ¼ by One-Way Endobronchial Valves.

Lung hyperinflation is a main determinant of dyspnoea in patients with chronic obstructive pulmonary disease (COPD). Surgical or bronchoscopic lung volume reduction are the most efficient therapeutic approaches for reducing hyperinflation in selected patients with emphysema. We here report the case of a 69-year old woman with COPD (GOLD stage 3-D) referred for lung volume reduction. She complained of persistent disabling dyspnoea despite appropriate therapy. Chest imaging showed marked emphysema heterogeneity as well as severe hyperinflation of the right lower lobe. She was deemed to be a good candidate for bronchoscopic treatment with one-way endobronchial valves. In the absence of interlobar collateral ventilation, 2 endobronchial valves were placed in the right lower lobe under general anaesthesia. The improvement observed 1 and 3 months after the procedure was such that the patient no longer met the pulmonary function criteria for COPD. The benefit persisted after 3 years.

Histopathologic Examination of Trabecular Meshwork Changes After Trabecular Bypass Stent Implantation.

PURPOSE: The purpose of this article was to evaluate how human trabecular meshwork (TM) is influenced by the chronic presence of trabecular bypass implants. METHODS: Human TM samples were obtained intraoperatively from 3 patients who had previously undergone implantation of a trabecular micro-bypass stent. Trabecular strips were obtained with a goniotomy blade from areas directly adjacent to the stent after stent removal. Tissue samples were preserved, processed, cut, and stained according to standardized laboratory protocol. Harvested samples were compared with human cadaveric TM from an eye without ocular disease as well as TM obtained from a glaucomatous eye without prior stent placement. RESULTS: In all samples, a significant increase in the amount of fibrous material compared with cellular material was noted when compared with controls. In a single strip, a basement membrane-like structure was noted, which correlated with a semiopaque membrane noted intraoperatively overlying the stent and adjacent TM. Further, TM cells were absent from areas adjacent to the stent implantation site with related collapse of collagen beams. CONCLUSIONS: These findings indicate that inflammatory and fibrotic changes are present surrounding the device with clear differences noted when compared with both healthy and glaucomatous controls. These changes suggest a possible etiology for device failure over time. Further studies are necessary to tease out differences in TM tissue reaction to various implant materials as well as to make comparisons to procedures that excise TM.

Two-Stage Osseointegrated Reconstruction of Post-traumatic Unilateral Transfemoral Amputees.

A new technique called osseointegration was introduced recently by intimately connecting the artificial limb prosthesis to the residual bone, eliminating the problematic socket-residuum interface. The objective here is to describe the two-stage strategy for the osseointegrated reconstruction of amputated limbs and discuss the clinical outcomes of the procedure. This is a prospective case series of 37 post-traumatic unilateral transfemoral amputees with a minimum 2-yr follow-up. Outcome measures included the Questionnaire for persons with a Transfemoral Amputation (Q-TFA), the Short Form Health Survey 36 (SF-36), the 6 Minute Walk Test (6MWT), and Timed Up and Go (TUG) tests. Adverse events including infection, revision surgery, fractures, and implant failures were reported. Clinical outcomes for all outcome measures were significantly improved at follow-up. Twelve participants were wheelchair bound pre-operatively; however, all 12 were able to ambulate after osseointegrated reconstruction. Sixteen patients experienced infection episodes but were managed successfully without the need for implant removal. One periprosthetic fracture occurred due to increased activity, which was revised successfully. These results confirm that the procedure is a suitable alternative for post-traumatic unilateral transfemoral amputees experiencing socket-related discomfort, with the potential to reduce recovery time compared with other treatment protocols.

Percutaneous Osseointegrated Prostheses for Transfemoral Amputations.

The direct attachment of the osseointegrated prosthesis to the skeleton avoids the inherent problems of socket suspension. It also permits physiological weight bearing, improved range of motion in the proximal joint, and osseoperceptive sensor feedback, enabling better control of the artificial limb by amputees. This article describes the osseointegration program in Sweden based on the use of bone-anchored prostheses for transfemoral amputation rehabilitation. The authors discuss in detail the patient-centered evaluation, surgical technique, and postoperative rehabilitation protocol. The outcomes of a prospective study of transfemoral amputees using the bone-anchored prostheses are presented. [Orthopedics. 2018; 41(2):75-80.].

Radial head prosthesis: surgical tips and tricks.

Radial head prostheses (RHP) have been developed to decrease the complications rate following a radial head resection surgery. The aim of the RHP is to replicate the physiological radiocapitellar tracking, reproducing the mechanical function of the native radial head: to stabilize the elbow and to shear the forces passing through the elbow along with the other stabilizers. The currently used RHP models try to achieve this target with three different prosthesis' strategies: (a) loose fit stem, (b) bipolar radial head or (c) anatomical radial head. Even if the radial head fixation is the preferred technique in every possible case and the resection can be still considered a possible option, in the last years there has been a growing worldwide consensus in using the radial head replacement in patients with unfixable radial head fractures, especially if associated with complex elbow instability. However, complications after a RHP are not uncommon, and their rate is raising as long as the implants number are increasing. The main difficulties are due to the implantation technique that needs to be performed with the same attention and precision used for the replacement of all the other joints, and to the concurrent treatment of the associated lesions. A personalized postoperative rehabilitation program is essential for obtaining good results and decreasing the complications rate. Concern exists for the young age of the patients that often require a RHP: personal experience and literature analysis suggest that if the clinical and radiographic results are positive after a 6-12-month follow-up, good outcomes can be also expected at a medium- or long-term follow-up.

Rehabilitation programs after the implantation of transfemoral osseointegrated fixations for bone-anchored prostheses: a systematic review protocol.

REVIEW QUESTION: The primary objective of this scoping review is to characterize rehabilitation programs for individuals with transfemoral amputation following the implantation of screw-type or press-fit osseointegrated fixations for bone-anchored prostheses.The secondary objective of this review is to describe partial weight bearing exercises including static and dynamic exercises as well as use of walking aids in each rehabilitation program for screw-type and press-fit fixations.The third objective of this review is to compare key rehabilitation parameters for various partial weight bearing exercises (e.g. type of training prosthesis, loading time and progression, monitoring of loading, loading direction, instructions given to patients and the use of loading regulators) within each program for screw-type and press-fit fixations (intra-variability) and between programs for screw-type and press-fit fixations (inter-variability).The specific review questions are.

Gait rehabilitation for a patient with an osseointegrated prosthesis following transfemoral amputation.

BACKGROUND: In patients with a transfemoral amputation socket-related problems are associated with reduced prosthetic use, activity, and quality of life. Furthermore, gait asymmetries are present that may explain secondary complaints. Bone-anchored prostheses (BAPs) may help these patients. Two types of BAP are available, screw and press-fit implants. Rehabilitation following surgery for a press-fit BAP is poorly described. PURPOSE: To describe a rehabilitation program designed to minimize compensation strategies and increase activity using a case-report of an active, 70-year-old man with a traumatic transfemoral amputation who had used a socket prosthesis for 52 years and received a press-fit BAP [Endo-Exo Femoral Prosthesis - EEFP]. INTERVENTION: A 13-week physiotherapy program. OUTCOMES: Outcomes were assessed before surgery, at the end of rehabilitation, and six-month and one-year follow-ups. After rehabilitation gait had improved, the patient had more arm movement, more pelvic shift, less hip rotation during swing phase on the prosthetic side, and absence of vaulting on the sound side. Isometric hip abductor strength was 15% higher on the sound side and 16% higher on the prosthetic side, and walking distance increased from 200 m to 1500 m. At the six-month follow-up, the patient had lower back complications and reduced hip abductor strength and walking distance. At one-year follow-up, walking distance had recovered to 1000 m and gait pattern had improved again, with yielding and absence of terminal impact on the prosthetic side. CONCLUSION: The described rehabilitation program may be an effective method of improving gait in patients with an EEFP even after long-term socket usage.

Physical Therapist-Led Ambulatory Rehabilitation for Patients Receiving CentriMag Short-Term Ventricular Assist Device Support: Retrospective Case Series.

BACKGROUND AND PURPOSE: Short-term ventricular assist device (VAD) support is used in the intensive care unit (ICU) to support individuals in end-stage heart failure prior to heart transplantation or implantation of a long-term left VAD. The literature investigating the feasibility, safety, and content of rehabilitation for this patient group is lacking. This report retrospectively describes the rehabilitation strategy, safety measures used, and nature of any adverse events and, therefore, the feasibility of this practice. CASE SERIES DESCRIPTION: Ten individuals (80% male) admitted to the ICU in critical cardiogenic shock required support via a short-term VAD. A prerehabilitation risk assessment was used to reduce the risk of cannula dislodgement. The therapeutic strategy was a stepwise progression of exercises, mobilization, and ambulation. OUTCOMES: Retrospective inspection of the case notes showed 330 rehabilitation sessions (X̅=33, SD=18.1, range=16-72) were performed and progressed to ambulation on 71 occasions (X̅=7.1, SD=7.7, range=1-27). Distance ambulated ranged from 7 to 1,200 m (X̅=157.7, SD=367.3). The Chelsea Critical Care Physical Assessment Tool (CPAx) score for 7 patients improved from a median of 0 (interquartile range=0-1) on day 1 to a median peak score of 39 (interquartile range=37-42). There were 8 episodes of minor adverse events (2.4% incidence rate), including 7 of transient low VAD flows. There were no major adverse events. DISCUSSION: Early rehabilitation and ambulation of recipients of short-term VAD support was safe and feasible. Recipients demonstrated improvements in physical function (CPAx score) while the VAD was in situ.

[Femtosecond-assisted Ferrara intrastromal corneal ring implantation for treatment of keratoconus: Functional outcomes at one year]. / Anneaux intra-cornéens Ferrara implantés au laser femtoseconde dans le traitement du kératocône : résultats fonctionnels à 1 an.

INTRODUCTION: Intrastromal corneal rings (ICR) have been used for several years for the correction of irregular astigmatism in patients with keratoconus. OBJECTIVE: To evaluate the effectiveness of femtosecond-assisted ICR implantation for treatment of keratoconus and to define predictive factors of success. PATIENTS AND METHODS: We undertook a retrospective study of patients with keratoconus who underwent femtosecond-assisted Ferrara ICR implantation between December 2012 and May 2014 at the University Hospital of Besançon. To determinate predictive factors of success, we divided patients into 2 groups based on the gain of at least two lines of best corrected visual acuity (BCVA) at 1 year after surgery ("good responders") or the gain of only one line of BCVA, no change, or the loss of lines of BCVA ("poor responders"). For each group, we analyzed preoperative refractive and keratometric values. Moreover, to verify if preoperative visual acuity could be a predictive factor of success, four groups were created based on initial visual acuity, and postoperative BCVA was compared. RESULTS: We retrospectively studied 32 eyes of 29 patients with keratoconus who underwent femtosecond-assisted Ferrara ICR implantation between December 2012 and May 2014 at the University Hospital of Besançon. From one month to 1 year postoperatively, we observed a significant improvement in BCVA and a significant decrease in cylinder and keratometry values (P<0.05). In total, 90.6% of patients had an increase in visual acuity (VA) of at least one line within 1 year while 9.4% had a decrease or stability of their VA. The average cylinder value decreased from -4.81±2.45 diopters (D) preoperatively to -2.39±1.94 D (P<0.001) at 1 year postoperatively, and the average of the maximum keratometry from 51.14±3.89 D to 48.52±4.00 D (P<0.05). Four predictive factors of success were statistically significant: type of ectasia (type 1 or 2), stage of keratoconus (Krumeich 1 or 2), implantation of only 1 ICR and a preoperative VA less than 0.4 (decimal scale). Eighty-six percent of patients with an initial VA<0.4 (decimal scale) gained 2 lines of BCVA within 1 year and 80% 3 lines versus 52% and 41%, respectively for patients with initial VA≥0.4 (decimal scale). CONCLUSION: Femtosecond-assisted Ferrara ICR implantation for treatment of keratoconus is a reliable and reversible technique. Implantation results in greater efficiency for patients with moderately advanced asymmetric keratoconus with an initial VA<0.4 (decimal scale).

Function of obturator prosthesis after maxillectomy and prosthetic obturator rehabilitation / Função da prótese obturadora após maxilectomia e reabilitação protética obturadora

ABSTRACT INTRODUCTION: Maxillary defects are usually rehabilitated by a prosthetic obturator. OBJECTIVE: This study aimed to evaluate the functioning of obturators prosthesis in patients with unilateral defects after maxillectomy. METHODS: Of 49 patients, 28 underwent to maxillectomy as a result of tumor ablative surgery, and acquired unilateral maxillary defects. Evaluation of the function was performed by applying the Obturator Functional Scale (OFS). RESULTS: From a total of 49 patients, 28 were treated as follows: 9 with a conventional retained obturator prosthesis (COP), 11 (39%) with an enhanced retentive obturator prosthesis with stud attachment (POP) and 8 (28%) with an enhanced retentive obturator prosthesis with magnetic attachment (POM). The mean OFS score was 80. Scores on functions of speech, swallowing and chewing reached statistical significances (p < 0.05) among these three subgroups. Comparing COP and MOP groups, the scores of OFS in the domains of "Speech-ability to speak in public" and "Swallowing-leakage with liquids" were significantly higher in AOP group. Comparing COP group, the scores of OFS in "Swallowing-leakage with solid" and "Chewing/eating" domains were increased significantly (p < 0.05) both in MOP and AOP groups. CONCLUSION: Obturator prosthesis improves oral function of patients after maxillary defects; the retention of the obturator prosthesis enhanced by the addition of attachments showed more benefits in oral function.

RESUMO INTRODUÇÃO: Em geral, os defeitos da maxila são reabilitados por uma prótese obturadora. OBJETIVO: O estudo avaliou o funcionamento da prótese obturadora em pacientes com defeitos unilaterais após maxilectomia. MÉTODO: De 49 pacientes, 28 foram submetidos a maxilectomia como cirurgia de ablação tumoral e tiveram como sequela defeitos maxilares unilaterais. A avaliação do funcionamento foi efetuada pela aplicação da Escala Funcional do Obturador (EFO). RESULTADOS: De um total de 49 pacientes, 28 foram tratados da seguinte forma: nove com prótese obturadora retentiva convencional (POC), 11 (39%) com prótese obturadora retentiva com fixação por pino (POP) e oito (28%) com prótese obturadora retentiva com fixação magnética (POM). O escore médio na EFO foi de 80. Os escores para funções da fala, deglutição e mastigação alcançaram significância estatística (p < 0,05) entre os três subgrupos. Na comparação entre os grupos POC e POM, os escores da EFO nos domínios da "Fala-capacidade de discursar em público" e "Deglutição-vazamento de líquidos" foram significativamente mais altos no grupo POP. Na comparação com o grupo POC, os escores da EFO nos domínios de "Deglutição-vazamento com sólido" e "Mastigação/ingestão" estavam significativamente aumentados (p < 0,05) nos grupos POM e POP. CONCLUSÃO: A prótese obturadora melhorou o funcionamento oral de pacientes com defeitos maxilares; a retenção da prótese obturadora reforçada pela adição de dispositivos de fixação demonstrou maiores benefícios na função oral.

Daily life activity in patients with left ventricular assist devices.

PURPOSE: Exercise capacity is usually evaluated by peak oxygen consumption (peak-VO2). However, assessment of peak-VO2 in patients with a left ventricular assist device (LVAD) might not be the best method to provide insight into their daily life activity. The aim of this study was to assess the postoperative activity of LVAD patients using actigraphy and to compare these patients to a healthy and a heart-transplanted (HTx) population. METHODS: Activity was continuously monitored using wrist-accelerometers in LVAD patients after implantation, during 4 weeks of rehabilitation following hospital discharge, and at 2 follow-up assessments. Peak-VO2 values measured during rehabilitation were correlated with activity. Additionally, actigraphy data from LVAD recipients were compared with data measured in healthy and HTx subjects. RESULTS: After hospital discharge a significant increase in physical activity of LVAD recipients was observed (55 ± 28 vs. 102 ± 23 Activity Scores, n = 11, p = 0.002). During rehabilitation as well as at the follow-ups (140 ± 43 and 253 ± 33 days post-implantation) no significant increase in activity was observed. Peak-VO2 values correlated to daily activity both in LVAD and HTx patients (r > 0.5). Average daily activity was significantly lower in LVAD and HTx patients than in the healthy population (130 ± 30 and 148 ± 60 vs. 245 ± 63 Activity Score; n = 18 in each group, p < 0.001). CONCLUSIONS: Activity in LVAD recipients increased substantially after hospital discharge with no further significant improvement observed during a period of 8.5 months. Similarly to the peak-VO2, also the daily activity of LVAD recipients was 53% compared to healthy subjects. These results highlight the need for an optimized physical therapy in this patient cohort.
