Unilateral cochlear implantation in elderly patients: assessment of the auditory and non-auditory functions of patients

Introduction. One of the few ways to rehabilitate profound hearing loss in elderly patients is cochlear implantation. A number of studies have been published assessing the effect of unilateral cochlear implantation on cognitive function in elderly patients, but the results have been mixed.Aim. Evaluation of the impact of unilateral cochlear implantation on auditory and non-auditory functions in elderly patients.Materials and methods. The study included 50 elderly and senile patients (mean age 67.16 ± 3.5 years). RBANS-H, HI-MoCA tests were used to assess cognitive function. Quality of life, depression and anxiety levels were assessed by HADS, SF-36. Auditory function was assessed by pure tone audiometry, speech audiometry, SSQ, HISQUI19.Results. The study showed improvement in cognitive function in patients with and without residual hearing. There was also an improvement in quality of life, a decrease in depression and anxiety in both study groups. When assessing the auditory function, statistically significant differences between the study groups remained during the study for the sound quality indicator (SSQ test), while other parameters did not have a statistically significant difference at the end of the study. In addition, the study did not reveal a statistically significant effect of vestibular dysfunction on cognitive function in patients.Conclusions. Unilateral CI as a method of rehabilitation of profound impairments of auditory function in elderly and senile patients has demonstrated its high effectiveness.

Major clinical relevance and considerations of zygomatic implants in elderly patients: a systematic review

For decades, zygomatic implants (ZI) have been used to rehabilitate atrophic maxillae and reconstruct maxillary defects, demonstrating significant survival rates, and have emerged as an alternative to extensive bone grafting. Despite their efficacy, surgical techniques for ZI placement have consistently been associated with perioperative complications, with additional problems arising later, especially in elderly patients. Objective: The present study developed a systematic review to address the main clinical relevance and considerations of zygomatic implants in elderly patients. Methods: The present study followed a concise systematic review model. The search was carried out in the PubMed, Embase, Ovid, Cochrane Library, Web of Science, and Scopus databases. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: A total of 220 articles were found. In total, 77 articles were fully evaluated and 57 were included and evaluated in this study, and of the total of 57 articles, only 42 articles were developed in the item results of the systematic review. Of the initial total of articles, 108 articles were excluded because they did not meet the GRADE and AMSTAR-2 classification, and 20 were excluded because they presented a risk of bias that could compromise the credibility of the studies. The symmetric funnel plot does not suggest a risk of bias. According to the GRADE instrument, most studies presented homogeneity in their results, with X2=85.6%>50%. It was concluded the ZI has a high rate of survival accumulated in 12 years, with the majority of failures occurring in the early stages of the postoperative period. The main complication observed related to zygomatic implants in elderly patients was sinusitis, which can appear several years after implantation surgery. The presence of increased maxillary sinus pneumatization with advanced resorption of the posterior alveolus may result in insufficient bone to anchor the implant. Bone augmentation is generally necessary under these conditions to allow the placement of a sufficient number and length of implants. Another more serious condition would be defects of maxillectomy, aplasia of the maxillary sinus, and cleft deformities. Zygomatic implants appear to be a consolidated therapeutic option for a significantly atrophic maxilla in elderly patients, offering a promising alternative to costly heavy bone graft techniques, fewer complications, less time for rehabilitation, less required prosthodontic work, and significantly higher survival rates.

Stemless RSA shows good short-term radiological stability and clinical outcomes in elderly patients

BackgroundThe main goal of this study was to investigate the influence of patient age on humeral implant fixation in stemless reverse shoulder arthroplasty (RSA). The secondary goals were to investigate the influence on the occurrence of complications and on clinical outcomes. MethodsWe performed a retrospective multicenter study, including a series of patients operated on for stemless RSA. All patients were reviewed at a minimum of 2 years, with clinical and radiographic evaluation. The primary endpoint was the occurrence of migration of the humeral implant at the final follow-up. Secondary endpoints were clinical scores, occurrence of postoperative complications, need for revision surgery, and radiographic changes. Each patient ≥70 year old was matched on gender and body mass index,with a patient < 70 year old on a 1:1 basis. ResultsForty-five patients aged ≥70 years were included and matched, with 45 patients aged <70 years, giving a total of 90 patients (54.4% men) with the mean age being 68.5 ± 7.9 years. There was no difference between the 2 groups in terms of surgical modalities. There was no correlation between age and clinical outcomes. Three migrations of the humeral implant occurred, none leading to a revision, without any influence of age (P = 1.0). We found no correlation between patient age and the occurrence of a postoperative complication (P = 1.0), reoperation (P = 1.0) or any of the other radiographic parameters assessed. ConclusionThis study reported the stability of stemless RSA implants in elderly patients. Clinical outcomes, complication, and revision rates were not affected by age either.

Early outcomes of a triple-branched stent graft implantation in elderly patients with acute type a aortic dissection

PurposeOlder patients with acute type A aortic dissection (ATAAD) have higher risk of mortality than that of younger patients when a total arch reconstruction (TAR) is required. Triple-branched stent graft (TBSG) implantation is a novel technique for TAR. However, early outcomes of a TBSG implantation in older patients have not been reported. This study aimed to evaluate the early outcomes of the TBSG technique in older patients with ATAAD.MethodsFrom February 2015 to December 2020, 640 patients who simultaneously underwent an emergent open aortic surgery and TBSG implantation for ATAAD were enrolled in this study. They were categorized into the younger (age ≤ 70 years old, n = 573) and older groups (age > 70 years, n = 67). Clinical data of all patients were retrospectively reviewed.ResultThe mean ages of the patients in the younger and older groups were 45.3 ± 9.6 years old and 73.5 ± 3.0 years old, respectively. Preoperative characteristics were similar between the two groups, except for weight and incidence of moderate or greater aortic regurgitation, which were lower in the older group than those in the younger group. Surgical procedure and duration (i.e., duration for cardiopulmonary bypass, aortic cross-clamp, selected cerebral perfusion, and total circulation arrest) were comparable between the two groups (p > 0.05). Patients in the older group had higher incidence of dialysis for acute kidney injury and longer ICU stay compared with those in the younger group. However, the incidences of 30-day mortality (5.1% in younger group vs. 7.5% in older group, p = 0.407) and other major complications (i.e., neurological adverse events) were similar between the two groups.ConclusionTBSG implantation for ATAAD resulted in an acceptable mortality rate in patients above 70 years old, thus, it could be a feasible surgical procedure to perform in older patients with ATAAD when a TAR is required.

Simultaneous hybrid off-pump coronary artery bypass grafting and transcatheter aortic valve implantation in elderly patients.

Optimal strategy for transcatheter aortic valve implantation (TAVI) in patients with coronary artery disease (CAD) is unresolved. We evaluated the surgical outcomes of hybrid coronary artery bypass grafting (CABG) and TAVI in elderly patients. We retrospectively evaluated patients who underwent simultaneous TAVI and CABG at Wakayama Medical University, Japan. All patients underwent off-pump CABG (OPCAB) including minimally invasive cardiac surgery (MICS-CABG). In an earlier period, OPCAB + transfemoral TAVI (TF-TAVI) was the only method used, while in a later period, we introduced MICS-CABG and alternative approaches for TAVI. Twenty-seven patients were enrolled, the average age was 83.6 ± 5.1years. In the MICS-CABG and TAVI group, average patient age was higher (87.0 ± 3.1years) than in the earlier group. Thirty-day and in-hospital mortalities were zero. Incomplete revascularization rate was 33.3% and one patient required percutaneous coronary intervention after the operation. Graft patency rate was 100%. In MICS-CABG group, the number of distal anastomoses was smaller (1.29, range 1-2), but the number of days required to re-starting walking and postoperative hospital stay were shorter, and the rate of discharge to home was higher (100%) than in the other groups. Although 33.3% of patients did not achieve complete revascularization, there was no 30-day or in-hospital mortality. TAVI and hybrid OPCAB, including MICS-CABG, were suggested to be feasible treatment in elderly patients.

Predictors of mortality and clinical outcomes following implantable cardioverter-defibrillator therapy in elderly patients: A retrospective single-center cohort study.

Implantable cardioverter-defibrillators (ICDs) are frequently used to prevent sudden cardiac death in patients with high-risk arrhythmias. However, the use of ICD therapy in elderly patients beyond the predicted age of life expectancy is still controversial. We aimed to evaluate the predictors of mortality and clinical outcomes following ICD implantation in elderly patients. We conducted a retrospective analysis of 145 elderly patients aged 72 years and older who received ICD implantation between January 2010 and August 2015. We collected and analyzed baseline data, including clinical, demographic, and medical history, the reason for ICD therapy, procedural data, and echocardiography results. Follow-up data included the development of complications and mortality. The predictors of mortality were identified using the univariate and multivariable Cox regression models. During the median follow-up duration of 30.5 [18.0-48.0] months, 141 cases completed follow-up (mean age = 76.0 ± 3.7 years). Forty-four patients experienced at least one episode of ICD therapy. Inappropriate shock, recurrent shock, and device-related infection were the most frequent complications observed in our study. Of the 145 patients, 42 died during the follow-up period, with an average survival time of 22.4 months after ICD implantation. Among these patients, 11 received ICD for primary prevention, and 31 received it for secondary prevention. Cardiovascular problems were the leading cause of death. We found that a low baseline ejection fraction (EF) was an independent predictor of mortality (hazard ratio = 0.93, 95% confidence interval: 0.90-0.98; p = 0.008). Our study suggests that ICD therapy is a valuable treatment option for elderly patients beyond their predicted age of life expectancy. The study highlights the importance of baseline EF as a significant predictor of mortality in these patients.

Analysis of rehabilitation effects of cochlear implantation in elderly patients with prelingual deafness

Objective:The auditory and speech rehabilitation effects were assessed by the Categories of Auditory Performance（CAP） and the speech intelligibility rating scale（SIR） after cochlear implantation（CI） in prelingually elderly patients by telephone follow-up or face-to-face conversation. Methods:The clinical data of the prelingually deaf patients who underwent unilateral CI in the Department of Otorhinolaryngology and Head and Neck Surgery, Shanxi People's Hospital, from December 2016 to December 2021 were collected. Thirty-eight patients were divided into Group A（SIR 1, 17 cases）, Group B（SIR 2, 10 cases） and Group C（SIR 3, 11 cases） according to the preoperative SIR Score. Nineteen patients with post-lingual hearing impairment were selected as the control group（Group D, 19 cases）. The effects of hearing and speech rehabilitation were evaluated using CAP and SIR Scores before surgery, 6 months after startup, and 1 year after startup. Results:There were no significant differences in CAP scores among the three groups of patients with prelingually deaf patients at 6 months and 1 year after startup（P>0.05）, but there were significant differences between group A and group D at 6 months and 1 year after startup（P<0.05）; the SIR Score of group A had statistical difference before surgery and 6 months after startup（P<0.05）, group B had statistical difference before surgery and 1 year after startup（P<0.05）, and group C and D had no statistical difference before surgery and 6 months and 1 year after startup, respectively（P>0.05）. Conclusion:For the prelingually deaf elderly patients, hearing will develop rapidly 6 months after startup, and the effect of postoperative auditory rehabilitation was positively correlated with the preoperative speech ability. In the aspect of speech, the prelingually dear elderly patients who have poor preoperative speech ability could benefit more from CI early after surgery. CI is not contraindicated in prelingually deaf elderly patients, even those with poor preoperative speech function.

Leadless pacemaker implantation in elderly patients with abandoned transvenous pacemakers with depleted batteries.

This spotlight article gives two clinical case examples for the implementation of a suggested safe and feasible strategy to implant leadless pacemakers instead of changing the generators of transvenous pacemakers with depleted batteries in elderly patients.

Effect of Dapagliflozin on Clinical Outcome after Drug-Eluting Stent Implantation in Elderly T2DM Patients: A Real-World Study.

To investigate the effect of dapagliflozin therapy on the clinical outcome of drug-eluting stent (DES) implantation in elderly patients with type 2 diabetes mellitus (T2DM). We retrospectively studied the real-world data of patients with coronary heart disease who received DES implantation in our hospital from May 2019 to May 2021. Baseline general data and laboratory results of patients were collected. All patients were followed up for two years after PCI, and the follow-up endpoints included in-stent restenosis, major adverse cardiovascular events (MACE), revascularization, rehospitalization, and all-cause mortality. Compared with those before treatment, body mass index, systolic blood pressure, diastolic blood pressure, TG, TC, LDL-C, FBG, and HbA1c were decreased in both groups after treatment, while HDL-C was increased after treatment (P < 0.05). There were significant differences in BMI, systolic blood pressure, diastolic blood pressure, FBG, and HbA1c between the two groups before and after treatment. At the end of follow-up, the incidence of in-stent restenosis and MACE in the dapagliflozin group was lower than that in the nondapagliflozin group. K-M curve analysis showed a significant difference in in-stent restenosis and MACE after DES implantation between the dapagliflozin group and the nondapagliflozin group (logrankχ2 = 5.093, 4.524; P = 0.024, 0.033). In accurate clinical data, dapagliflozin could significantly improve the postoperative BMI, blood pressure, and blood glucose outcome of patients with T2DM complicated with coronary heart disease and positively impact in-stent restenosis and MACE.

Analysis of risk factors affecting mortality in elderly patients operated on for hip fractures: A retrospective comparative study.

The aims of this study were (1) to investigate the effects of different demographic and perioperative modalities on mortality rates and (2) to compare mortality rates between different implants in elderly patients operated on for hip fractures. In this retrospective study, a total of 314 patients who were operated on for hip fractures were included study. Patients were then divided into four groups based in their implant types: long-stem cementless bipolar hemiarthroplasty (n = 124; 102 female, 22 male; mean age = 84.2 ± 6.4 years), standard-stem cementless bipolar hemiarthroplasty (n = 74; 48 female, 26 male; mean age = 83.5 ± 6.9 years), antegrade intertrochanteric nail (n = 61; 35 female, 26 male; mean age = 78.5 ± 6.8 years), and total hip arthroplasty (n = 55; 34 female, 21 male; mean age = 72.5 ± 4.3 years). Data including gender, age, duration from injury to surgery, American Society of Anesthesiologists (ASA) score, comorbidities, use of antiplatelet agents, Barthel Index of Activities of Daily Living, type of anesthesia, operation time, preoperative hemoglobin values, blood transfusions given, duration of hospital stay, complications, and type of fracture were recorded. Overall, the mean follow-up was 36.5 (range = 0 - 107) months. The overall mortality rate was 53.2%. The median survival duration was 44.2 ± 5 months (range = 34.3 - 54). Survival rates were found significantly different among the groups (P = 0.001). In the first three years postoperatively, the mortality rate was higher in the standard-stem bipolar hemiarthroplasty group, but in the long-term follow-up, the long-stem bipolar hemiarthroplasty group exhibited the higher mortality rates. It was observed that some parameters had statistically significant effects on the mortality rates. Male gender, higher age, lower hemoglobin values, increased number of blood transfusions, ASA scores ≥3, the existence of ≥ 3 comorbidities were found as main predictors of increased mortality rates. The results of this study have shown that age, gender, preoperative hemoglobin levels, ASA scores, and comorbidities are significant factors affecting mortality in elderly patients operated on for hip fractures. Long-stem cementless bipolar hemiarthroplasty appears to show similar rates of mortality with standard-stem cementless bipolar hemiarthroplasty. Level III, Therapeutic Study.

Cochlear Implantation in Elderly Patients with Residual Hearing.

This retrospective study aimed to investigate the range of hearing levels in a cochlear implant (CI) elderly population receiving electric-acoustic-stimulation (EAS) or electric-stimulation (ES) alone. The investigation evaluates the degree of hearing preservation (HP) and the speech comprehension resulting from EAS or ES-only to identify audiometric factors that predict adequate EAS and ES use. We analyzed the pure tone audiometry and speech perception in quiet and noise preoperatively and 12-months after activation of 89 elderly adults (age of 65 years old or older), yielding in total 97 CIs. Thirty-two (33.1%) patients were potential EAS candidates preoperatively, of which 18 patients used EAS at the time of first fitting and the other 14 patients continued to use their residual hearing for EAS at 12-months. Post-treatment, patients with EAS system and ES-only users’ with longer electrodes showed better results in monosyllable word scores in quiet than ES-only users with shorter electrodes. A similar trend was revealed for the speech recognition in noise. Patients with an EAS system benefit from maintaining their natural residual hearing. Nevertheless, strict preoperative patient selection is warranted particularly in elderly patients, in whom the hearing thresholds for EAS indication differ slightly from that in younger adults.

Cochlear Implantation in Elderly Patients: Survival Duration, Hearing Outcomes, Complication Rates, and Cost Utility

Introduction: The prevalence of hearing loss and its consequences is increasing as the elderly population grows. As the guidelines for cochlear implantation (CI) expand, the number of elderly CI recipients is also increasing. We report complication rates, survival duration, and audiological outcomes for CI recipients aged 80 years and over and discuss the cost utility of CI in this age group. Methods: A retrospective cohort study was undertaken of all CI recipients (126 cases), aged 80 years and over at the time of their surgery, implanted at our institution (Cambridge University Hospitals) during a period from January 1, 2001, to March 31, 2019. Data on survival at 1, 3, and 5 years post-implantation, post-operative complications and functional hearing outcomes including audiometric and speech discrimination outcomes (Bamford-Kowal-Bench sentence test) have been reported. Results: The mean age at implantation was 84 years. The mean audiometric score improved from 108 dB HL to 28 dB HL post-implantation. The mean Bamford-Kowal-Bench score improved from 14% to 66% and 73% at 2 and 12 months post-implantation, respectively. The complication rate was 15.3%. The survival probability at 1 year post-implantation was 0.95 for females and 0.93 for males, at 3 years was 0.89 for females and 0.81 for males, and at 5 years was 0.74 for females and 0.54 for males. Conclusion: CI is safe and well-tolerated in this age group and elderly patients gain similar audiometric and functional benefit as found for younger age groups.

Hearing Outcomes and Complications of Cochlear Implantation in Elderly Patients over 75 Years of Age.

Objective: Populations are aging in many countries, and the proportion of elderly people with severe to profound hearing loss is increasing in parallel with the increasing average life span. The objective of this study was to investigate the outcomes of cochlear implant (CI) surgery in elderly patients compared to those in younger patients. Methods: The outcomes of CI surgery were retrospectively investigated for 81 adults (32 men and 49 women) who underwent CI surgery at our hospital. They were divided according to age at the time of implantation into the younger group (<75 years of age; n = 49) or elderly group (≥75 years of age; n = 32). Results: The mean sentence recognition score on the CI-2004 Japanese open-set test battery (±standard deviation) was 82.9% ± 24.1 in the younger group and 81.9% ± 23.2 in the elderly group, with no significant difference between the groups (Mann–Whitney U test). The incidence of major complications that required surgical treatment was not significantly different between the groups (4.1% vs. 6.2%, respectively). Thus, there were no severe complications that could affect general health status in either group. Three patients in each group died for reasons unrelated to CI surgery during follow-up. The proportion of patients who were alive and continued to use the CI five years after surgery was 92.8% and 91.5%, respectively. Conclusion: Our results show good speech recognition and a low incidence of major complications in elderly patients. This comprehensive report on the outcomes of CI surgery in elderly patients will be helpful to the elderly with severe to profound hearing loss when deciding whether to undergo CI surgery.

Association of furosemide or hydrochlorothiazide use with risk of atrial fibrillation post pacemaker implantation among elderly patients.

BackgroundAtrial fibrillation (AF) induced by artificial pacing is directly related to atrial remodeling. Previous basic research has shown that furosemide aggravates pathologic myocardial remodeling while hydrochlorothiazide alleviates it. However, whether furosemide or hydrochlorothiazide plays a role in developing AF after pacemaker implantation remains unknown. The study aims to investigate the association between oral furosemide or hydrochlorothiazide and the risk of developing AF after pacemaker implantation.MethodsAfter a review of electronic medical records, elderly patients with pacemaker implantation and without a known baseline history of AF were included and information on their use of daily oral furosemide or hydrochlorothiazide was extracted. New incident AF cases were confirmed via the records of outpatient visits. A Cox proportional-hazards model was used to evaluate the association between daily oral furosemide or hydrochlorothiazide and risk of developing AF after pacemaker implantation, after adjustment for potential confounders.ResultsAmong a total of 551 patients aged more than 65 years, 157 AF cases were identified after pacemaker implantation during a maximum follow up of 3.0±1.6 years. Of these, 242 had used furosemide and 97 had used hydrochlorothiazide therapy. Patients taking daily oral furosemide had a relatively higher risk of AF after pacemaker implantation [hazard ratio (HR): 1.507, 95% confidence interval (CI): 1.036–2.192; P=0.032] after being adjusted for related disease and prescribed medications, while oral taking of hydrochlorothiazide was shown to be a non-effective factor (HR: 0.666, 95% CI: 0.413–1.074), which had no statistical significance.ConclusionsDaily oral furosemide might increase the risk of developing AF after pacemaker implantation in elderly patients, while hydrochlorothiazide has no detrimental effect.

Leadless pacemaker vs conventional single chamber pacemaker for urgent permanent implantation in elderly and very elderly patients

Abstract Funding Acknowledgements Type of funding sources: None. Background Data on feasibility of leadless pacemaker (LPM) in the elderly and very elderly is scarce. We aimed to investigate the security and feasibility of urgent LPM implantation in elderly patients. Methods Observational study of a prospective register of consecutive patients that underwent LPM insertion in a single centre. Elderly (≥75 years) and very elderly patients (≥85 years) that underwent LPM implantation in a non-elective setting between June 2016 and January 2020 were eligible. We compared pacing thresholds, R wave and impedance at baseline, short- and long term follow-up. Furthermore, we compared complication rate and all-cause mortality of LPM patients to patients that underwent conventional SCP insertion. Results 78 elderly patients (25 LPM, 53 SCP) with a mean age of 82.4 and 83.8 years, respectively (p = 0.82), were included in the study. The mean follow-up time was 11.2 months. 35 patients (11 LPM, 24 SCP) had an age of ≥ 85 years. There were no significant differences with respect to demographic and baseline clinical data between LPM patients and SCP patients. (Table) Furthermore, we did not find significant changes in pacing thresholds, R wave and impedance on short- and long-term follow-up. Complication rates at 12 months of elderly and very elderly LPM patients were similar to those that underwent conventional SCP implantation (0% vs 5.7%, p = 0.35; 0% vs 4.2%, p = 0.41, respectively). Likewise, we did not find significant differences regarding all-cause mortality (12% vs 13%, p = 0.92; 9% vs 25%, p = 0.18). Comparing Kaplan-Meier curves, no significant differences were found regarding 12 month complication rate and all-cause mortality between LPM patients and conventional SCP patients, as assessed by Log Rank test (p = 0.98 and p = 0.91, respectively). (Figure) Conclusion LPM implantation is a feasible and secure alternative to conventional SCP insertion in elderly and very elderly patients, even in a non-elective setting.

A Novel, Minimally Invasive Method to Retrieve Failed Dental Implants in Elderly Patients

This practice-based study presents the clinical outcomes of a minimally invasive method for retrieving failed dental implants from elderly patients. Traditional removal methods for failed dental implants include trephination and other invasive procedures. That can be a special concern for the elderly, since aging exacerbates oral surgery-related morbidity and anxiety. This retrospective cohort study gathers data from 150 patients seen in a private clinic. Their implants (n = 199) failed due to biological, mechanical, or iatrogenic causes, and were removed as part of their treatment plan. Collected data included: (1) implant location (maxilla/mandible, anterior/posterior region), (2) reasons for implant retrieval, (3) connection type, (4) removal torque, and (5) operatory procedure—flapless and using a counter-torque removal kit, whenever possible. Flapless/minimally invasive retrieval was successful for 193 implants (97%). The remaining six implants demanded trephination (open-flap). The most common reasons for implant retrieval (81%) involved biological aspects, whereas iatrogenic (12%) and biomechanical (7%) reasons were less common. The surgical technique used was not associated to connection types or removal torque. Authors conclude that a counter-torque ratchet system is a minimally invasive technique with a high success rate in retrieving implants from elderly patients. Present findings support its use as a first-line approach for implant retrieval in that population.

Percutaneous cementoplasty of periprosthetic loosening: can interventional radiologists offer an alternative to revision surgery?

To evaluate feasibility and validate both safety and efficiency of radiological percutaneous periprosthetic bone cementoplasty (RPPBC) performed under local anesthesia as an alternative minimally invasive treatment of aseptic implant loosening. In this case series, seven patients (mean age 81years, range 73 to 89years, 2 men and 5 women) were enrolled between February 2011 and January 2020 with confirmed aseptic loosening of orthopedic implants. One patient presented with tibial component loosening of an unicompartmental knee arthroplasty, one with glenoid component loosening from a reverse shoulder arthroplasty, one femoral gamma nail, and four presented with pedicle screw loosening after staged posterior lumbar interbody fusion. All patients underwent clinical, biochemical, and imaging assessments to confirm the diagnosis of aseptic loosening. All benefited from RPPBC under dual CT and fluoroscopic guidance. All procedures were performed under local anesthesia by an experienced radiologist. Preprocedural, immediate and 6-month post-cementoplasty pain levels on a visual analogue scale (VAS), and functional outcomes were evaluated. Immediate and 6-month postprocedural CTs were performed to evaluate the treated region. All RPPBC were well tolerated by patients throughout the procedure. None of the patients suffered from local or systemic infection post-RPPBC, or periprosthetic fractures. No recurrent implant loosening was observed. Six patients were pain free at 6months. All patients expressed functional improvements during validated outcome score evaluations. RPPBC appears to be an efficient and reliable treatment strategy for aseptic loosening of orthopedic implants in elderly patients deemed unfit for revision surgery. • Radiological percutaneous periprosthetic bone cementoplasty offers immediate and long-lasting pain relief in elderly frail patients, or those deemed unfit for revision surgery despite presenting with symptomatic aseptic loosening of orthopedic implants. • Radiological percutaneous periprosthetic bone cementoplasty brings quick and long-lasting improvements in clinical functional outcomes and offer effective pain reduction, thereby improving the overall quality of life. • Radiological percutaneous periprosthetic bone cementoplasty is a safe, quick, reliable, and well-tolerated minimally invasive procedure which can be easily performed under simple locoregional anesthesia and requires short-term hospital stay.

Long-term prognosis of drug eluting stents implantation in elderly patients with unprotected left main coronary artery disease

Objective: To analyze the clinical characteristics and long-term prognosis of implantation of drug-eluting stents (DES) for elderly patients with unprotected left main artery (ULM) disease. Methods: A total of 414 patients (327 males and 87 females) who underwent DES implantation were enrolled in the Department of Cardiology, Beijing Anzhen Hospital from January 2005 to March 2010, with a mean age of (61.5±10.7) years old. The patients were divided into two groups according to age: 300 cases in the group of age <70 years old, and 114 cases in the group of age ≥70 years old. The clinical characteristics and long-term prognosis of two groups were compared. Results: In the group of age ≥ 70 years old, the proportion of female was higher (31.6% vs 17.0%, P=0.001) and the incidence of chronic total occlusion (CTO) (P=0.020), hypertension (P=0.018) and cerebrovascular disease (P=0.013) were higher than those in the group of <70 years old. All-cause mortality and cardiac mortality were also higher than those in the group of <70 years old (P=0.025, P=0.013). The follow-up period was (21.4±9.6) months. After adjusting for multiple clinical factors, there were no statistical differences of incidence of the total major adverse cardiac and cerebral events (MACCE), myocardial infarction, cerebrovascular events, and revascularization recurrence between the two groups. But all-cause mortality (HR=3.790, 95%CI: 1.271-11.298, P=0.017) and cardiac mortality (HR=17.424, 95%CI: 2.440-124.410, P=0.004) in the group of age ≥70 years old were still remarkably higher than those in the group of <70 years old. Conclusions: Age is an independent risk factor for increased mortality after DES stent implantation in ULM disease. DES stent implantation in age ≥70 years old patients with ULM disease is considered feasible, but it needs to be treated with caution.

The Outcomes of Cochlear Implantation in Elderly Patients: A Single United Kingdom Center Experience.

The average life expectancy in the United Kingdom is currently nearly 80 years for a newborn baby with nearly 15% of the population, by 2040, being >75 years old. Hearing impairment is a common disability in the elderly individual, and there have been significant drives to support this population to lead longer and healthier working lives. We aimed to assess the long-term audiological and health-related quality-of-life benefits of cochlear implants (CI) in elderly individuals. A retrospective and cross-sectional study of patients who received a CI at ≥70 years. Data extracted included speech perception scores, adverse events, telephone use, and patient-reported outcome measures using the Glasgow Benefit Inventory questionnaire with a minimum of 12 months follow-up. Sixty-four patients aged ≥70 years received a unilateral CI. A significant improvement in speech perception scores in all conditions was noted with no significant difference between differing age groups. Glasgow Benefit Inventory scores showed a significant positive impact on patients' lives and their health status, with no significant difference between the differing age groups. Cochlear implantation is a safe and well-tolerated procedure in the elderly patients with significant improvements observed in audiological performance, health status, and social interactions.

Assessment of postoperative nutritional status and physical function between open surgical aortic valve replacement and transcatheter aortic valve implantation in elderly patients.

Background and aims : Severe aortic stenosis (AS) has been normally treated with surgical aortic valve replacement (AVR) whereas recently, transcatheter aortic valve implantation (TAVI) has been introduced as a minimally invasive operation for patients with high surgical risk and frailty. In this study, we have evaluated postoperative physical function and nutrition intake in the patients following AVR and TAVI. Methods : This prospective observational study involved 9 patients with surgical aortic valve replacement (AVR) and 7 patients with transcatheter aortic valve implantation (TAVI). Body composition was measured one day prior surgery, postoperative day (POD) 1, POD 3, POD 5 and POD 7. Hand grip strength, calf circumference and gait speed were measured one day before surgery and on the day of discharge. Results : Skeletal muscle was significantly decreased in AVR patients at postoperative day 3 and 7, while there was no change in TAVI patients. Patients with TAVI showed higher dietary intake after surgery compared to patients with AVR, and they maintained hand grip strength and calf circumference at discharge. Conclusions : In elderly patients with AS, TAVI can improve post-operative recovery maintaining nutritional status and physical function even. J. Med. Invest. 67 : 139-144, February, 2020.
