Social Interactions between Family and Community-Based Service Providers in Dementia Caregiving.

Objectives: This study aimed to evaluate the psychosocial experiences in community-based dementia caregiving by assessing the characteristics of social interactions between family caregivers and community-based service providers and associated psychological responses.Methods: Two independent groups of participants (family caregivers and community-based service providers) completed a one-time survey to report their social interactions and psychological states. A linear regression model was fit for each outcome (satisfaction, 10-item CES-D) while controlling for significant relevant covariates.Results: Higher perceived levels of collaboration were associated with higher job satisfaction and lower depression score among service providers, and higher satisfaction with providers among family caregivers. Higher perceived social support from the provider was associated with higher satisfaction among family caregivers.Conclusions: Participants reported varying levels of provider-family collaboration. The extent of collaborations and support exchange may have implications on the psychological well-being of those providing care to individuals with dementia including families and providers.Clinical implications: It may be beneficial to identify providers and families who perceive low levels of collaboration and implement intervention to facilitate positive social interactions. Developing organizational culture and payment systems that value high-quality social interactions may help enhance the psychological well-being of service providers and satisfaction among families who receive their services.

Respiratory Musculature Evaluated by Computed Tomography in the Setting of Prolonged Mechanical Ventilation.

BACKGROUND: Diaphragm atrophy has been observed in subjects who undergo invasive mechanical ventilation. We propose a new method to assess for respiratory muscle (RM) changes in subjects who undergo invasive mechanical ventilation by assessing for changes in respiratory muscles through computed tomography (CT). METHODS: A retrospective case series study was conducted on subjects who underwent invasive mechanical ventilation and received at least 2 chest CT scans during admission. Exclusion criteria included history of chronic mechanical ventilation dependence and neuromuscular disease. Respiratory muscle cross-sectional area (CSA) was measured at the T6 vertebrae. RESULTS: Fourteen subjects were included: mean (± SD) age, BMI, and admission APACHE II scores were 54.0 y (± 14.9), 32.6 kg/m2 (± 10.9), and 23.5 (± 6.0), respectively. Ten (71%) subjects were male. Mean length of time between CT chest scans was 7.5 d (± 3.3). Mean duration of invasive mechanical ventilation was 4.5 d (± 3.4). The percentage change in TM CSA among those who underwent invasive mechanical ventilation was 10.5% (± 6.1). CONCLUSIONS: We demonstrated that serial analysis of respiratory muscle CSA through CT chest scans can be a method to assess for respiratory muscle atrophy in subjects undergoing mechanical ventilation. Future prospective studies involving larger populations are needed to better understand how this method can be used to predict outcomes in mechanically ventilated patients.

Graft repair of arteriovenous fistula aneurysms is associated with decreased long-term patency.

INTRODUCTION: Arteriovenous fistula (AVF) aneurysms are a chronic complication which can be disfiguring, painful, and can rupture. Here, we compare the outcomes between three different methods of AVF aneurysm repair. METHODS: One-way ANOVA, Chi-square, and Fisher Exact analyses were used to compare demographics. Multivariate logistic regression compared outcomes. Kaplan-Meier estimate illustrated long-term fistula patency. RESULTS: There were no differences between demographics in the aneurysmorrhaphy, end-to-end anastomosis, and synthetic graft groups. The odds of patients who received graft repair losing primary patency within one year compared to the aneurysmorrhaphy group was 3.5 (p = 0.025). Graft repair patients were 6.7 times more likely to develop an infection compared to aneurysmorrhaphy (p = 0.014). Synthetic grafts also exhibited accelerated rates of complete access loss compared to autogenous methods (p = 0.034). CONCLUSIONS: Graft repair of AVF aneurysms results in higher rates of infection and decreased primary and ultimate patency compared to autogenous repair techniques. Therefore, synthetic grafts should be avoided whenever possible.

End-to-end anastomosis as a superior repair type to prevent recurrence of arteriovenous fistula aneurysms and improve patency outcomes.

BACKGROUND: Arteriovenous fistulae (AVF) complicated by aneurysms are repaired through several mechanisms. Little is known about risk factors for aneurysm recurrence or the efficacy of subsequent repair of recurring aneurysms. METHODS: About 291 patients underwent AVF aneurysm repair between 2009 and 2019 at a large urban medical center. Patients who underwent staged repair, had a primary graft with pseudoaneurysm, were status-post kidney transplant, or using other dialysis access at the time of repair were excluded. One hundred sixty-two patients were included in the study, of which 52 developed a secondary aneurysm. Chi-square and t-test analyses were used to compare demographics. Multivariate logistic regression was used to examine independent risk factors for aneurysm recurrence. Of the 52 patients with recurrent aneurysms, 41 were repaired again. Patency was examined for each group 1 year postoperatively. RESULTS: Patients without secondary aneurysms were more likely to have a Charlson Comorbidity Index score ⩾5 (p = 0.045). Males were 2.8 times more likely to develop a secondary aneurysm compared to females (p = 0.023). Patients who underwent elective compared to emergent or urgent surgery for primary aneurysms were significantly less likely to recur (OR = 0.222; p = 0.016). Primary aneurysms repaired by end-to-end anastomosis, compared to aneurysmorrhaphy or graft, were significantly less likely to recur (OR = 0.239; p = 0.041). Among patients with secondary aneurysms, those repaired via end-to-end anastomosis had a significantly higher primary patency rate 1 year postoperatively (p = 0.024). Secondary aneurysm repairs exhibited 1-year primary and secondary patency rates of 51.2% and 82.9%, respectively. CONCLUSIONS: End-to-end anastomosis reduces risk of recurrence and demonstrates superior patency rates when repairing recurrent aneurysms. It remains unclear why some patients are prone to aneurysm recurrence, however continued attempts to repair existing vascular access are proven to be successful.

New Persistent Opioid Use After Orthopaedic Foot and Ankle Surgery: A Study of 348 Patients.

INTRODUCTION: The opioid epidemic is a devastating public health issue to which orthopaedic surgery is inextricably linked. The purpose of this study was to identify risk factors for new persistent opioid use after orthopaedic foot and ankle surgery among patients who were opioid naive preoperatively. METHODS: Patients undergoing orthopaedic foot or ankle surgery at a single institution were identified. Our state's prescription monitoring program was used to track opioid prescriptions filled in the preoperative (6 months to 30 days before surgery), perioperative (30 days before to 14 days after), and postoperative (2 to 6 months after) periods. Patients filling a prescription during the preoperative period were excluded. Baseline characteristics, surgical characteristics, and perioperative morphine milligram equivalents were tested for association with new persistent use during the postoperative period. RESULTS: A total of 348 opioid-naive patients met the inclusion criteria. Overall, the rate of new persistent postoperative opioid use was 8.9%. Patients reporting recreational drug use had the highest risk, at 26.7% (relative risk [RR] = 3.3, 95% confidence interval, 1.3 to 8.2, P = 0.0141). In addition, patients who had perioperative opioid prescription >160 morphine milligram equivalents were at increased risk (RR = 2.2, 95% confidence interval, 1.1 to 4.5, P = 0.021). Other risk factors included age ≥40 years (RR = 2.2, P = 0.049) and consumption of ≥6 alcoholic beverages per week (RR = 2.1, P = 0.040). New persistent use was not associated with ankle/hindfoot surgery (versus midfoot/forefoot), bone surgery (versus soft-tissue), or chronic condition (versus acute; P > 0.05). CONCLUSION: The rate of new persistent postoperative opioid use after orthopaedic foot and ankle surgery is high, at 8.9%. Greater perioperative opioid prescription is a risk factor for new persistent use and is modifiable. Other risk factors include recreational drug use, greater alcohol use, and greater age. Orthopaedic foot and ankle surgeons should limit perioperative prescriptions and be cognizant of these other risk factors to limit the negative effects of opioid prescriptions on their patients and communities. LEVEL OF EVIDENCE: Level III.
