Fried Frailty Phenotype Questionnaire scores and postoperative patient-reported outcomes of patients undergoing major abdominal cancer surgery: A secondary analysis.

AIM: This study aimed to evaluate the effects of Fried Frailty Phenotype Questionnaire (FFPQ) scores on patient-reported postoperative outcomes. METHODS: This secondary analysis of a prospective observational study included 230 inpatients aged ≥65 years undergoing elective abdominal cancer surgery. The primary outcome was the Quality of Recovery-15 score on postoperative days 2, 4 and 7. The secondary outcomes included disability-free survival, defined as a 12-item World Health Organization Disability Assessment Schedule 2.0 score of <16% at 3 months. The associations of the FFPQ scores, ranging from 0 (robust) to 5 (frailty), with the primary and secondary outcomes were assessed using multiple analysis. RESULTS: After confirming the linearity of the FFPQ score for the outcomes, multiple regression analysis adjusted for prominent factors showed that the FFPQ score was a significant factor influencing the decrease in the Quality of Recovery-15 score on postoperative day 2 (ß = -2.67, 95% confidence interval -5.20, -0.15), 4 (ß = -3.54, 95% confidence interval -5.77, -1.30) and 7 (ß = -3.70, 95% confidence interval -5.75, -1.65). The adjusted odds ratio of the FFPQ score for disability-free survival postoperatively was 0.66 (95% confidence interval 0.49-0.90). CONCLUSIONS: Patients with higher FFPQ scores before elective major abdominal cancer surgery were likely to have lower postoperative Quality of Recovery-15 scores and poor disability-free survival.

Early Quality of Recovery after Elective Cardiothoracic and Aortic Surgeries in Adult Patients: A Pilot Report.

BACKGROUND: Patient-centered outcome measures should be evaluated postoperatively as the recovery after surgery varies between patients. We aimed to evaluate the feasibility, reliability, and trajectory of the quality of recovery-15 (QoR-15) in patients undergoing cardiothoracic and aortic surgeries. MATERIALS AND METHODS: This retrospective study included adult patients who underwent elective cardiothoracic and aortic surgeries. The primary outcome was the QoR-15, with a minimal clinically important difference of 6.8, assessed on postoperative days (POD) 2, 4, and 7. The final analysis included patients with at least one valid outcome. Feasibility and reliability were assessed by the successful completion rate on each POD and using Cronbach's alpha of the QoR-15 on POD 4. A linear mixed model was used to evaluate the trajectory of the postoperative QoR-15 scores. RESULTS: Of the 36 eligible patients, 30 with a mean age of 70 years were included in the final analysis. The successful completion rates on POD 2, 4, and 7 were 72.7%, 87.8%, and 87.8%, respectively. The mean QoR-15 scores on POD 2, 4, and 7 were 89.9, 98.0, and 108.3, respectively. The QoR-15 scores on POD 2 and 4 were not statistically different (P = 0.06) but were clinically significant. The QoR-15 score on POD 7 was statically (P < 0.001) and clinically higher than the QoR-15 score on POD 2. Cronbach's alpha for the QoR-15 score measured on POD 4 was 0.85. CONCLUSION: The QoR-15 is a feasible and valid measurement after elective cardiothoracic surgery, which increases significantly over time after surgery.

Association between preoperative frailty and surgical Apgar score in abdominal cancer surgery: a secondary analysis of a prospective observational study.

INTRODUCTION: The surgical Apgar score is useful for predicting postoperative morbidity and mortality. However, its applicability in frail patients with minimal hemodynamic variation remains unknown. This study aimed to investigate the association between frailty and surgical Apgar score. METHODS: This secondary analysis included 210 patients ≥ 65 years of age undergoing elective major abdominal surgery for cancer. Frailty was assessed using the Fried Frailty Phenotype Questionnaire and defined as a total score of ≥ 3. The surgical Apgar score (range, 0-10; including mean blood pressure, heart rate, and blood loss volume) was compared between patients with or without frailty using the Mann-Whitney U test. Postoperative severe complications and length of postoperative stay were compared between patients with surgical Apgar scores ≤ 7 and > 7. RESULTS: Among the included patients, 45 were classified as frail. The median [1st quartile, 3rd quartile] surgical Apgar scores in patients with and without frailty were 7.0 [7.0, 8.0] and 8.0 [7.0, 8.0], respectively (P = 0.03). Patients with surgical Apgar score ≤7 had a higher incidence of serious postoperative complications (P = 0.03) and longer hospital stays (P < 0.001) compared with patients with surgical Apgar score >7. CONCLUSION: Frail patients have lower SAS, and patients with lower SAS have higher postoperative complication rates and longer hospital stays in patients who underwent cancer surgery.

Comparison of self-reported symptoms in COVID-19 patients who had or had not previously received COVID-19 mRNA vaccination.

Although mRNA coronavirus disease 2019 (COVID-19) vaccines have been reported for high effectiveness against symptoms, it remains unclear whether post-vaccination infections are less symptomatic than infections in vaccine-naive individuals. We included patients with COVID-19 diagnosed by polymerase chain reaction tests during Japan's alpha and delta variant epidemics. COVID-19 symptoms at approximately 4 weeks were compared based on COVID-19 vaccination status. In total, 398 cases (372 symptomatic and 26 asymptomatic; 286 unvaccinated, 66 vaccinated with one dose, and 46 with two doses) were analyzed. The most common symptoms were fever (78.4%), fatigue (78.4%), cough (74.4%), loss of taste or smell (62.8%), and headache (59.8%). Post-vaccination infections were significantly less likely to be symptomatic. Possible confounder-adjusted odds ratios of two vaccine doses against fatigue, dry eyes and mouth, insomnia, fever, shortness of breath, unusual muscle pains, and loss of taste or smell were 0.18 (95% confidence interval [CI]: 0.09-0.38), 0.22 (95% CI: 0.08-0.59), 0.33 (95% CI: 0.14-0.80), 0.31 (95% CI: 0.15-0.63), 0.36 (95% CI: 0.16-0.76), 0.40 (95% CI: 0.19-0.82), and 0.44 (95% CI: 0.22-0.87), respectively. Post-vaccination infections after two mRNA COVID-19 vaccine doses show milder and fewer symptoms than infections in unvaccinated patients, highlighting the effectiveness of vaccination.

Quality of recovery in hospital and disability-free survival at three months after major abdominal surgery.

BACKGROUND: The Quality of Recovery-15 (QoR-15) and 12-item World Health Organization Disability Assessment Schedule 2.0 scales are post-surgery patient-reported outcome measures. We aimed to evaluate the association between immediate in-hospital postoperative recovery and mid-term disability-free survival (DFS) after discharge. METHODS: We conducted a prospective observational study at a university hospital and enrolled 260 patients aged ≥ 65 years with cancer who were undergoing elective major abdominal surgery. The association between poor postoperative recovery, defined as a QoR-15 score < 90 on postoperative day (POD) 2, and the DFS three months later was assessed using Fisher's exact test. The odds ratio of poor recovery on POD 2 to DFS was calculated using multiple logistic regression analysis adjusted for prominent factors (age, preoperative frailty, preoperative DFS, surgical duration, and intraoperative blood loss volume). RESULTS: A total of 230 patients completed the 3-month follow-up. On POD 2, 27.3% of the patients (63/230) had poor recovery. A greater number of patients without poor recovery on POD 2 had DFS at three months after surgery (79.6%) than those with poor recovery (65.1%) (P = 0.026). The adjusted odds ratio of poor recovery on POD 2 to DFS at three months was 0.481 (95% CI [0.233, 0.994]). CONCLUSIONS: Patients with poor recovery on POD 2 were less likely to have DFS three months after abdominal surgery. These findings may allow for early and effective interventions to be initiated based on each patient's condition after abdominal surgery.

Effects of preoperative nutritional status on postoperative quality of recovery: a prospective observational study.

Quality of Recovery-15 (QoR-15) has received attention as a postoperative patient-reported outcome measure. Preoperative nutritional status has negative effects on postoperative outcomes; however, these associations have not yet been investigated. We included inpatients aged ≥ 65 years who underwent elective abdominal cancer surgery under general anaesthesia between 1 June 2021 and 7 April 2022 at our hospital. Preoperative nutritional status was assessed using the Mini Nutritional Assessment Short-Form (MNA-SF), and patients with an MNA-SF score ≤ 11 were categorised into the poor nutritional group. The outcomes in this study were the QoR-15 scores at 2 d, 4 d and 7 d after surgery, which were compared between groups by unpaired t test. Multiple regression analysis was applied to assess the effects of poor preoperative nutritional status on the QoR-15 score on postoperative day 2 (POD 2). Of the 230 included patients, 33·9 % (78/230) were categorised into the poor nutritional status group. The mean QoR-15 value was significantly lower in the poor nutritional group than in the normal nutritional group at all postoperative time points (POD 2:117 v. 99, P = 0·002; POD 4:124 v. 113, P < 0·001; POD 7:133 v. 115, P < 0·001). Multiple analyses showed that poor preoperative nutritional status was associated with the QoR-15 score on POD 2 (adjusted partial regression coefficient, -7·8; 95 % CI -14·9, -0·72). We conclude that patients with a poor preoperative nutritional status were more likely to have a lower QoR-15 score after abdominal cancer surgery.

Prevalence of pre-operative undiagnosed cognitive impairment and its association with handgrip strength, oral hygiene, and nutritional status in older elective surgical patients in Japan.

PURPOSE: Preoperative cognitive impairment is a significant factor influencing post-operative delirium. We have been performing routine pre-operative comprehensive assessments, including evaluation of cognitive function, handgrip strength, oral hygiene, and nutritional status, in patients aged ≥ 65 years since April 2021. This study aimed to examine the completion rate of pre-operative comprehensive assessment and assess the prevalence of pre-operative undiagnosed cognitive impairment. METHODS: In this prospective observational study including patients aged ≥ 65 years scheduled for elective surgery with general or regional anesthesia, cognitive impairment was defined as a Mini-Cog score ≤ 2, and its associations with handgrip strength, oral hygiene, and nutritional status were evaluated. Oral hygiene and nutritional status were assessed using an oral frailty self-checklist and the Mini Nutritional Assessment-Short Form, respectively. The incidence of pre-operative undiagnosed cognitive impairment was estimated, and its associated factors were explored with multiple logistic regression. RESULTS: Among 331 eligible patients, the completion rate was 97.7% (305/312). The mean age was 74.8 years, and 13.1% (40/305) (95% confidence interval [CI], 9.7-17.3%) of the patients had pre-operative undiagnosed cognitive impairment. Multiple logistic regression revealed that handgrip strength (odds ratio [OR] = 0.94, 95%CI = 0.89-0.99) and oral frailty self-checklist score (OR = 1.19, 95%CI = 1.02-1.40) were associated with pre-operative undiagnosed cognitive impairment, while the Mini Nutritional Assessment-Short Form score was not significantly associated (OR = 0.97, 95%CI = 0.82-1.14). CONCLUSIONS: Preoperative comprehensive assessment was feasible. The prevalence of pre-operative undiagnosed cognitive impairment was 13%, and poor handgrip strength and worse oral hygiene were significantly associated factors.

Real-World Effectiveness of the mRNA COVID-19 Vaccines in Japan: A Case-Control Study.

The real-world effectiveness of the coronavirus disease 2019 (COVID-19) vaccines in Japan remains unclear. This case-control study evaluated the vaccine effectiveness (VE) of two doses of mRNA vaccine, BNT162b2 or mRNA-1273, against the delta (B.1.617.2) variant in the Japanese general population in the period June-September 2021. Individuals in close contact with COVID-19 patients were tested using polymerase chain reaction (PCR). A self-administered questionnaire evaluated vaccination status, demographic data, underlying medical conditions, lifestyle, personal protective health behaviors, and living environment. Two vaccine doses were reported by 11.6% of cases (n = 389) and 35.2% of controls (n = 179). Compared with controls, cases were younger and had a lower proportion who always performed handwashing for ≥20 s, a higher proportion of alcohol consumers, and a lower proportion of individuals living in single-family homes or with commuting family members. After adjusting for these confounding factors and day of PCR testing by multivariate logistic regression analysis, the VE in the period June-July (delta variant proportion 45%) was 92% and 79% in the period August-September (delta variant proportion 89%). The adjusted VE for homestay, hotel-based isolation and quarantine, and hospitalization was 78%, 77%, and 97%, respectively. Despite declining slightly, VE against hospitalization remained robust for ~3 months after the second dose. Vaccination policymaking will require longer-term monitoring of VE against new variants.
