Matching males and females undergoing non mesh primary unilateral inguinal hernia repair: evaluating sex differences in preoperative and acute postoperative pain.

PURPOSE: The objective was to compare pain and related psychological factors during the preoperative and acute postoperative period between male and female patients, who underwent non mesh primary unilateral inguinal hernia repair. METHODS: After ethics approval, informed consent was obtained, and data were collected. Male and female participants were compared by manually matching one-to-one on 10 variables. Descriptive statistics (mean ± standard deviation and frequency) as well as numerical rating scales from 0 to 10 were used. Comparison tests were performed using Chi-square or Fisher's Exact test for categorical data and independent samples t-test or non-parametric equivalent tests for numerical scores. p < 0.05 is reported as statistically significant. To control type I error, Bonferroni correction was used. RESULTS: 72 participants with 36 matched pairs were included. Sex differences were found for operation length (p = .006), side of operation (p = .002), and hernia type (p = .013). Significant differences between the sexes were not found at the preoperative or postoperative time for resilience, pain interference or pain severity related measures, postoperative hernia pain incidence, pain catastrophizing, depression and anxiety symptoms, or return to normal activities. CONCLUSION: When controlling for known confounders and using a conservative Type I error rate, pain and related factors between the sexes did not differ significantly.

Temporal patterns for inguinal hernia recurrence operations after Shouldice Repair.

PURPOSE: Shouldice Repair for inguinal hernias results in a low recurrence rate; however, little is known about the risk factors for these relapses. In the present study, we reviewed all patient's undergoing a reoperation for recurrence after a primary Shouldice Repair. METHODS: Patients undergoing recurrent inguinal hernia repair from 2013 to 2017 were identified. The subgroup of patients with the first recurrence after a Shouldice Repair at this institution was selected and included. Data collection from the index and the reoperation surgery were performed, as well as statistical analysis. RESULTS: A total of 125 patients were included in the analysis. The mean age was 50.8 ± 13.9 (body mass index: 24.6 ± 2.6 kg/m2), 97% were male. The most common interval for a recurrence reoperation was in the first 5 years following the initial surgery (37.6% of patients; mode: 1 year; median: 7 years; mean: 13.7 ± 13.8 years). A temporal median pattern for recurrence reoperation according to age interval was noted (patients < 41 years old: 20 years; patients aged 41-60 years old: 10 years and patients > 61 years: 2 years)). CONCLUSION: Patients undergoing reoperations for recurrent inguinal hernias after a primary Shouldice Repair presented a pattern of temporal recurrence according to age. Older patients present with earlier recurrences than younger ones, an important consideration in the assessment of patients postoperatively.

Validation and psychometric testing of the Arabic version of the mental health literacy scale among the Saudi Arabian general population.

OBJECTIVE: This study aimed to validate the Arabic Version of the Mental Health Literacy Scale (Arabic-MHLS) among the Saudi Arabian general population, assessing its internal consistency, test-retest reliability, and structural validity. METHODS: A total of 700 Arabic-speaking Saudi adults were randomly selected to complete the electronic questionnaire in May 2023, which generated 544 participants. Data were coded and stored in the ZdataCloud research data collection system database. Test-retest reliability was assessed using a subsample of 48 participants who completed the questionnaire twice, with a one-week interval. Structural validity was examined using confirmatory factor analysis (CFA) and Exploratory Factor Analysis (EFA). RESULTS: The Arabic-MHLS demonstrated good internal consistency (Cronbach's alpha = 0.87) and test-retest reliability (intraclass correlation coefficient = 0.89). EFA revealed a four-factor model closely resembling the model identified in the Slovenian validation of MHLS, with factor loadings ranging from 0.40 to 0.85. The four factors included knowledge of mental health disorders, knowledge of help-seeking, knowledge of self-help strategies, and knowledge of professional help also showed good internal consistency. CONCLUSION: The Arabic-MHLS is a valid and reliable tool for assessing mental health literacy in the Saudi Arabian general population. However, further research is needed to refine the measurement tool and understand the complex relationships between mental health literacy and other mental health-related concepts. This will contribute to the development of targeted interventions and policies aimed at improving mental health literacy and promoting mental well-being in the Saudi Arabian population and beyond.

QTc interval prolongation independently associates with FGF23 and predicts mortality in predialysis CKD.

INTRODUCTION: QTc interval prolongation is increasingly frequent as CKD advances and predicts death in dialysis. However, predictors and mortality-risk in predialysis CKD are understudied. FGF23 induces left ventricular hypertrophy (LVH) which is associated with QTc interval prolongation and death, suggesting a possible pathway from FGF23 to death that entails LVH and QTc prolongation. We looked for links between FGF23 and prolonged QTc intervals mediated by LVH, and for deaths associated with QTc prolongation in a prospective observational cohort of patients with predialysis CKD. METHODS: Participants underwent protocolized baseline and semi-annual FGF23 testing, baseline and study end echocardiograms, and baseline and annual electrocardiograms over three years. RESULTS: 2,254 participants (34.1% female; mean age 68.7 years; mean glomerular filtration rate 41.4 ml/min/m2) enrolled. Baseline LVH (left ventricular mass index >131 g/m2 (>100 g/m2 if female)) was present in 10.8% and prolonged QTc intervals (>=500 ms) in 1.5%. One hundred thirty-eight (6.1%) participants died during the study. In generalized mixed effects regression, each unit increase in the natural log of FGF23 - but not LVH - predicted an odds ratio of 1.76 (1.15, 2.70, p=0.009) for prolonged QTc intervals independently of 15 other covariates. Mediation analysis showed that only 13% of FGF23's total effect on prolonged QTc intervals was mediated by LVH. Patients with prolonged QTc intervals had higher unadjusted (log rank p<0.001) and adjusted (hazard ratio 3.15 (1.38, 7.16, p=0.006)) mortality rates than those with QTc intervals <500 ms. CONCLUSIONS: QTc interval prolongation ≥500 ms was prospectively associated with FGF23 independently of LVH, and with a tripling of mortality-risk in patients with predialysis CKD.

Incidence of opioid use and early postoperative pain intensity after primary unilateral inguinal hernia repair at a single-center specialty hospital.

PURPOSE: This research examined opioid use, pain intensity, and pain management after primary unilateral inguinal hernia repair (PUIHR) at a single-center specialty hospital. METHODS: After research, ethics board approval, and informed consent, pain scores (0-10 numerical rating scale [NRS]) were obtained from survey-based questionnaires administered at the pre- and 3-day postoperative timepoints. Descriptive results are presented as frequency, mean, standard deviation, range, median, and interquartile ranges, as appropriate. Significance tests were conducted to compare participants who did and did not receive opioids after surgery. p-value <0.05 is considered statistically significant. As the standard of care, participants received nonopioid multimodal analgesia (acetaminophen and nonsteroidal anti-inflammatory drugs (NSAIDs)) and opioids, when necessary. RESULTS: A total of 414 and 331 participants completed the pre- and 3-day postoperative questionnaires, respectively. Out of the 414 participants, 38 (9.2%) received opioids during the postoperative stay. There was no significant difference between pain frequency or mean preoperative NRS pain intensity scores of those who did and did not receive opioids. Mean NRS pain intensity scores on day 3 after surgery were significantly higher for participants who received opioids (3.15±2.08) than those who did not (2.19±1.95), p=0.005. CONCLUSION: Most participants did not receive opioids after PUIHR and had lower mean postoperative NRS pain intensity scores compared to those who did, most likely reflecting the need for opioids among the latter. Opioids were discontinued by day 3 for all participants who received them. Therefore, for most patients undergoing PUIHR, effective pain control can be achieved with nonopioid multimodal analgesia in the early postoperative period.

Single-Centre Retrospective Cohort Study of Demographic Characteristics and Perinatal Outcomes in Pregnant Refugee Patients in Toronto, Canada.

Pregnant refugee patients are especially vulnerable to adverse perinatal outcomes. Detailed characterization of this heterogenous population will identify risk factors and thus guide contextualized initiatives for improved patient care. A retrospective cohort study of obstetrical refugee patients at a tertiary-care hospital in Toronto, Ontario. Of 196 pregnant refugees, 48% were fluent English speaking, 57% had poor social support, and 42% lived in a shelter. Eighty-seven percent started prenatal care after the first trimester, which was associated with delivery of a large-for-gestational-age infant (p = 0.043). Sixteen percent experienced family violence, which was associated with poor fetal aggregate outcomes (p = 0.03). There were significantly higher rates of pre-eclampsia and Cesarean sections in refugee versus non-refugee patients (p < 0.05). Pregnant refugees are at risk for psychosocial challenges and experience significantly worse obstetrical outcomes compared with non-refugees. Quality improvement initiatives should focus on access to early prenatal care, stable housing, and support for victims of family violence.

Cultural adaptation and validation of the mental illness associated stigma scale for Arabic-speaking population in Saudi Arabia.

Objective: This research aimed to culturally adapt and validate the MIAS scale for Arabic-speaking individuals within the Saudi Arabian general population, with an emphasis on cultural, societal, and individual nuances. Methods: An initial pilot testing with a small group ensured the scale's clarity. Subsequently, two cross-sectional studies involving 189 participants to assess structural validity of the Arabic MIAS scale, and 38 participants to assess the test-retest reliability. Descriptive statistics, Cronbach's α, Intraclass Correlation Coefficient (ICC), and Confirmatory Factor Analysis (CFA) were employed for data analysis. Results: The Arabic MIAS scale demonstrated good internal consistency and acceptable test-retest reliability (ICC α = 0.631). A three-factor model emerged (CFI = 0.890, TLI = 0.845, RMSEA = 0.094), including "Outcomes," "Negative Stereotypes," and "Recovery," closely mirroring the original study's structure. one item was excluded from the model since it didn't align with any of the three factors. Conclusion: The study contributes a culturally adapted, validated, non-condition-specific tool to gauge public attitudes toward mental health stigma in an Arabic context. It highlights the need for culturally sensitive stigma research and interventions and underscores the importance of improving such tools for cross-cultural applicability and comparability.

Predictive Validity and Patterns of Change Over Time of the Sensitivity to Pain Traumatization Scale: A Trajectory Analysis of Patients Seen by the Transitional Pain Service Up to Two Years After Surgery.

Purpose: The Sensitivity to Pain Traumatization Scale (SPTS-12) was developed to assess the propensity to develop a traumatic stress response to pain. The SPTS-12 is a reliable and valid scale with a one-factor structure. The aim of the present study is to further examine the psychometric properties of the SPTS-12 by evaluating its criterion validity and how scores change over time in a sample of postsurgical patients at the Toronto General Hospital Transitional Pain Service. Participants and Methods: 361 adults (55% male; M age = 50.6 years, SD age = 14.3) completed questionnaires assessing symptoms of pain, anxiety, depression, and trauma at multiple visits to the Transitional Pain Service after surgery. Latent-class growth mixture modeling defined prototypical longitudinal patterns (latent trajectories) of SPTS-12 scores up to two years after surgery. One-way ANOVAs examined how trajectory classes differed over time on measures of daily opioid use (mg morphine equivalents (MME)), average pain intensity, pain interference, and depressive symptoms. Results: The final model consisted of five SPTS-12 trajectory groups; two characterized by a flat and unchanging pattern and three showing a small but statistically significant decrease over time. Analysis of pain-related outcomes predicted by SPTS-12 trajectories provided evidence of criterion validity of the SPTS-12. SPTS-12 trajectories did not significantly differ on daily MME at any time. Average pain, pain interference, and depression scores significantly differed across SPTS-12 trajectory groups at two or more postsurgical visits (all p < 0.05). Conclusion: The SPTS-12 shows fairly stable patterns and predicts important pain-related and psychosocial outcomes over time. Two SPTS-12 trajectories (#2 and #5) with high scores, comprising ~28% of the total sample, are associated with problematic outcomes on several pain and psychosocial measures. Targeting patients with high SPTS-12 scores for presurgical psychological treatment may prove beneficial in reducing the impact of CPSP.

Democratizing Flexible Endoscopy Training: Noninferiority Randomized Trial Comparing a Box-Trainer vs a Virtual Reality Simulator to Prepare for the Fundamental of Endoscopic Surgery Exam.

BACKGROUND: A considerable number of surgical residents fail the mandated endoscopy exam despite having completed the required clinical cases. Low-cost endoscopy box trainers (BTs) could democratize training; however, their effectiveness has never been compared with higher-cost virtual reality simulators (VRSs). STUDY DESIGN: In this randomized noninferiority trial, endoscopy novices trained either on the VRS used in the Fundamental of Endoscopic Surgery manual skills (FESms) exam or a validated BT-the Basic Endoscopic Skills Training (BEST) box. Trainees were tested at fixed timepoints on the FESms and on standardized ex vivo models. The primary endpoint was FESms improvement at 1 week. Secondary endpoints were FESms improvement at 2 weeks, FESms pass rates, ex vivo tests performance, and trainees' feedback. RESULTS: Seventy-seven trainees completed the study. VRS and BT trainees showed comparable FESms improvements (25.16 ± 14.29 vs 25.58 ± 11.75 FESms points, respectively; p = 0.89), FESms pass rates (76.32% vs 61.54%, respectively; p = 0.16) and total ex vivo tasks completion times (365.76 ± 237.56 vs 322.68 ± 186.04 seconds, respectively; p = 0.55) after 1 week. Performances were comparable also after 2 weeks of training, but FESms pass rates increased significantly only in the first week. Trainees were significantly more satisfied with the BT platform (3.97 ± 1.20 vs 4.81 ± 0.40 points on a 5-point Likert scale for the VRS and the BT, respectively; p < 0.001). CONCLUSIONS: Simulation-based training is an effective means to develop competency in endoscopy, especially at the beginning of the learning curve. Low-cost BTs like the BEST box compare well with high-tech VRSs and could help democratize endoscopy training.

Pain Among an Inpatient Complex Chronic Care Population of Residents with and without Missing Limbs.

PURPOSE: Limb loss occurs for various reasons (trauma, infection, vascular diseases, tumors, congenital absence). Limb loss is known to result in several types of pain. Little is known about pain in residents with missing limbs admitted to complex chronic care (CCC) facilities. This study examined the presence of pain and its intensity in CCC residents with and without missing limbs. METHODS: The Continuing Care Reporting System was accessed for data from residents admitted to Ontario com\plex chronic care facilities assessed with the Resident Assessment Instrument Minimum Data Set, V2.0. Propensity score matching (1:1 ratio) was used to identify a control resident without missing limbs for each case. McNemar's test was used for dichotomous pain (Y/N) and Wilcoxon Signed Ranks test for ordinal pain (4-level and 7-level pain variables). Binary and multinomial logistic regression were used to quantify the relationship between missing limbs and reports of pain. RESULTS: Missing limbs were reported by 2961 residents (2.1%, original n=139,920) resulting in 2212 propensity matched pairs. A significantly higher proportion of missing limb cases had pain (80%) versus controls (70%), χ 2=64.43, p<0.001. Significantly higher pain levels were found in cases versus controls (z=8.47, p<0.001 for 4-level pain; z=8.57, p<0.001 for 7-level pain). Residents with missing limbs were 1.46 (95% CI: 1.26-1.70) times more likely to report pain than controls, p<0.001. CONCLUSION: The results point to the need to better manage pain in CCC residents with missing limbs.

Hypertensive Hypoalgesia in a Complex Chronic Disease Population.

Hypertension-related hypoalgesia, defined as lower pain sensitivity in individuals with high blood pressure, has yet to be examined in a large-scale study of complex care residents. Here, the Continuing Care Reporting System database, which contains health information on residents of Canadian complex chronic care facilities, was used for assessment. Hypertension was reported among 77,323 residents (55.5%, total N = 139,920). Propensity score matching, with a 1:1 ratio, was used to identify a control record without hypertension for each case. Multinomial logistic regression was used to quantify the effects of hypertension and sex on four-level ordinal pain variables, controlling for potential confounders. The matched dataset included n = 40,799 cases with hypertension and n = 40,799 without hypertension, with 57% female. Residents with hypertension had significantly lower odds of reporting pain (yes/no) (OR = 0.85, 95% CI 0.81-0.90, p < 0.001), including on measures of severe pain (OR = 0.69, 95% CI 0.63-0.76, p < 0.001). A significant interaction between hypertension and sex (OR = 1.17, 95% CI 1.03-1.32, p = 0.014) indicated that a significantly greater proportion of females without hypertension reported severe pain (8.71%). The results confirm the relationship between hypertension and reduced pain sensitivity on a population level.

Development and prospective validation of a scoring system for the Basic Endoscopic Skills Training (BEST) box.

AIMS: The increased use of endoscopy as a minimally invasive therapeutic technique has created a great demand for endoscopic training. The Basic Endoscopic Skills Training (BEST) box provides a low-cost solution by adapting the Fundamentals of Laparoscopic Surgery (FLS) box for flexible endoscopic simulation. The BEST box consists of six endoscopic tasks with a 5-min time limit per task. This study aims to develop a scoring system for objective evaluation of user performance. METHODS: A total of 165 participants were tested on the BEST box. Participants were divided into two groups: retrospective analysis (n = 100) and prospective analysis (n = 65). From the retrospective group, 55 individuals were also scored on the Global Assessment of Gastrointestinal Endoscopic Skills-Upper Endoscopy (GAGES-UE). Linear regression between user performance on BEST box and GAGES-UE was performed to develop the scoring system. Receiver Operating Characteristic curve was used to determine a threshold score to help users appreciate their endoscopic expertise. Prospective scoring of 65 individuals was then performed using the formula developed (20 experts and 45 trainees). RESULTS: The minimum and maximum possible scores are 30 and 110, respectively. Retrospective analysis showed that the scoring system was able to distinguish between experts and trainees (p < 0.001), correlated with GAGES-UE (p < 0.001), and had a reliability constant of r = 0.765 (p < 0.001). On prospective testing using the scoring system the expert group received a final average score of 92, whereas the average score for the trainee group was 61 (p < 0.001). CONCLUSIONS: The developed BEST box scoring system correlates with the experience level of the test taker as well as with the GAGES-UE scoring system. The results of this study add further evidence to the validity of the BEST box as an effective, low-cost endoscopic simulator with the scores used by trainees to track their performance level overtime.

Association Between Multimorbid Disease Patterns and Pain Outcomes Among a Complex Chronic Care Population in Canada.

PURPOSE: Disease multimorbidity and pain is a complex, yet common, problem for the aging population, and a significant burden on the health-care systems around the world. Despite this, disease comorbidity and the association with pain in a complex chronic care population is not well understood. This study examined the most prevalent disease combinations and their association with pain. PATIENTS AND METHODS: The study initially included 139,920 residents, aged 18-101 years, admitted to publicly funded hospital facilities for complex chronic care in Canada between the years 2006 and 2016. Data were acquired through the Canadian Institute for Health Information (CIHI) Facility-Based Continuing Care Reporting System (CCRS). Descriptive and chi-square statistics were used to summarize and compare the sample characteristics. Binary logistic regression analyses were used to examine the association between multimorbid disease categories and pain outcomes. RESULTS: The sample consisted of 139,573 residents (57% female), mostly older (mean age = 77.32 years), married (40%), or widowed (36%). Residents took an average of 11.9 medications and 77% were using analgesic medications. On average, residents had diagnoses from 3.06 disease categories (SD = 1.43). Heart/circulation diseases were the most prevalent among the sample (73%), with neurological second (46%) and musculoskeletal third (44%). Overall, 73% of residents reported pain, with 43% reporting moderate pain severity. Residents with multiple disease categories were more likely to report the presence of pain (OR = 1.08, 95% CI: 1.07-1.08, p < 0.001), with each additional disease category associated with an 8% increase in the odds of reporting pain. CONCLUSION: The findings from this study help identify common comorbid disease patterns related to pain in an institutionalized, complex chronic care population. This information contributes to both the pain and multimorbidity literature, and is invaluable for creating care plans to meet the demands of a challenging population.

Comparison of the Accuracy of Short Cognitive Screens Among Adults With Cognitive Complaints in Turkey.

BACKGROUND: Cutoff values of cognitive screen tests vary according to age and educational levels. OBJECTIVE: The objective of this study was to compare the accuracy and determine cutoffs for 3 short cognitive screening instruments: the Mini-Mental State Examination, Montreal Cognitive Assessment (MoCA), and Quick Mild Cognitive Impairment Screen-Turkish version (Qmci-TR), in older adults with low literacy in Turkey. METHODS: In all 321 patients, 133 with subjective cognitive complaints (SCC), 88 amnestic-type mild cognitive impairment (aMCI), and 100 with probable Alzheimer disease (AD) with a median of 5 years education were included. Education and age-specific cutoffs were determined. RESULTS: For the overall population, the Qmci-TR was more accurate than the MoCA in distinguishing between aMCI and AD (area under the curve=0.83 vs. 0.76, P=0.004) and the Qmci-TR and Mini-Mental State Examination were superior to the MoCA in discriminating SCC from aMCI and AD. All instruments had similar accuracy among those with low literacy (primary school and lower educational level or illiterate). CONCLUSIONS: To distinguish between SCC, aMCI, and AD in a sample of older Turkish adults, the Qmci-TR may be preferable. In very low literacy, the choice of the instrument appears less important.

Comparison of dietary macronutrient patterns of 14 popular named dietary programmes for weight and cardiovascular risk factor reduction in adults: systematic review and network meta-analysis of randomised trials.

OBJECTIVE: To determine the relative effectiveness of dietary macronutrient patterns and popular named diet programmes for weight loss and cardiovascular risk factor improvement among adults who are overweight or obese. DESIGN: Systematic review and network meta-analysis of randomised trials. DATA SOURCES: Medline, Embase, CINAHL, AMED, and CENTRAL from database inception until September 2018, reference lists of eligible trials, and related reviews. STUDY SELECTION: Randomised trials that enrolled adults (≥18 years) who were overweight (body mass index 25-29) or obese (≥30) to a popular named diet or an alternative diet. OUTCOMES AND MEASURES: Change in body weight, low density lipoprotein (LDL) cholesterol, high density lipoprotein (HDL) cholesterol, systolic blood pressure, diastolic blood pressure, and C reactive protein at the six and 12 month follow-up. REVIEW METHODS: Two reviewers independently extracted data on study participants, interventions, and outcomes and assessed risk of bias, and the certainty of evidence using the GRADE (grading of recommendations, assessment, development, and evaluation) approach. A bayesian framework informed a series of random effects network meta-analyses to estimate the relative effectiveness of the diets. RESULTS: 121 eligible trials with 21 942 patients were included and reported on 14 named diets and three control diets. Compared with usual diet, low carbohydrate and low fat diets had a similar effect at six months on weight loss (4.63 v 4.37 kg, both moderate certainty) and reduction in systolic blood pressure (5.14 mm Hg, moderate certainty v 5.05 mm Hg, low certainty) and diastolic blood pressure (3.21 v 2.85 mm Hg, both low certainty). Moderate macronutrient diets resulted in slightly less weight loss and blood pressure reductions. Low carbohydrate diets had less effect than low fat diets and moderate macronutrient diets on reduction in LDL cholesterol (1.01 mg/dL, low certainty v 7.08 mg/dL, moderate certainty v 5.22 mg/dL, moderate certainty, respectively) but an increase in HDL cholesterol (2.31 mg/dL, low certainty), whereas low fat (-1.88 mg/dL, moderate certainty) and moderate macronutrient (-0.89 mg/dL, moderate certainty) did not. Among popular named diets, those with the largest effect on weight reduction and blood pressure in comparison with usual diet were Atkins (weight 5.5 kg, systolic blood pressure 5.1 mm Hg, diastolic blood pressure 3.3 mm Hg), DASH (3.6 kg, 4.7 mm Hg, 2.9 mm Hg, respectively), and Zone (4.1 kg, 3.5 mm Hg, 2.3 mm Hg, respectively) at six months (all moderate certainty). No diets significantly improved levels of HDL cholesterol or C reactive protein at six months. Overall, weight loss diminished at 12 months among all macronutrient patterns and popular named diets, while the benefits for cardiovascular risk factors of all interventions, except the Mediterranean diet, essentially disappeared. CONCLUSIONS: Moderate certainty evidence shows that most macronutrient diets, over six months, result in modest weight loss and substantial improvements in cardiovascular risk factors, particularly blood pressure. At 12 months the effects on weight reduction and improvements in cardiovascular risk factors largely disappear. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42015027929.

Screening for Cognitive Frailty Using Short Cognitive Screening Instruments: Comparison of the Chinese Versions of the MoCA and Qmci Screen.

BACKGROUND: Cognitive frailty describes cognitive impairment associated with physical decline. Few studies have explored whether short cognitive screens identify frailty. We examined the diagnostic accuracy of the Chinese versions of the Quick Mild Cognitive Impairment (Qmci-CN) screen and Montreal Cognitive Assessment (MoCA-CN) in identifying cognitive frailty. METHODS: Ninety-five participants with cognitive symptoms [47 with mild cognitive impairment (MCI), 34 with subjective cognitive disorder, and 14 with dementia] were included from two outpatient rehabilitation clinics. Energy (work intensity) and physical activity levels were recorded. Cognitive frailty was diagnosed by an interdisciplinary team using the IANA/IAGG consensus criteria, stratified on the Clinical Frailty Scale (CFS). Instruments were administered sequentially and randomly by trained assessors, blind to the diagnosis. RESULTS: The mean age of the sample was 62.6 ± 10.2 years; median CFS score was 4 ± 1 and 36 (38%) were cognitively frail. The Qmci-CN had similar accuracy in differentiating the non-frail from cognitively frail compared to the MoCA-CN, AUC 0.82 versus 0.74, respectively (p = 0.19). At its optimal cut-off (≤55/100), the Qmci-CN provided a sensitivity of 83% and specificity of 67% versus 91% and 51%, respectively, for the MoCA-CN (≤23/30). Neither was accurate in separating MCI from cognitive frailty but both accurately separated cognitive frailty from dementia. CONCLUSION: Established short cognitive screens may be useful in identifying cognitive frailty in Chinese adults with cognitive complaints but not in separating MCI from cognitive frailty. The Qmci-CN had similar accuracy to the MoCA-CN and a shorter administration time in this small and under-powered study, necessitating the need for adequately powered studies in different healthcare settings.

Associations between echocardiographic findings and prospective changes in residual renal function in patients new to peritoneal dialysis.

Although echocardiograms are often performed when peritoneal dialysis is started, associations between commonly reported findings and prospective changes in renal function remain understudied. Ninety-nine of 101 patients in the Trio Trial had transthoracic echocardiograms within 6 months of dialysis initiation, and measurements of residual renal function every six weeks for up to two years. Generalized mixed modelling linear regression in STATA was used to examine associations between left atrial size, left ventricular hypertrophy, left ventricular ejection fraction, right ventricular systolic pressure, and left valvular calcification with subsequent slopes in renal function. After echocardiography (performed a median of 16 days following peritoneal dialysis initiation) right ventricular systolic pressure was associated with faster, while declining left ventricular ejection fraction and valvular calcification were associated with slower declines in residual renal function. Future studies could be conducted to confirm these findings, and identify pathophysiological mechanisms.

Reducing inappropriate prescribing for older adults with advanced frailty: A review based on a survey of practice in four countries.

The management of medications in persons with frailty presents challenges. There is evidence of inappropriate prescribing and a lack of consensus among healthcare professionals on the judicious use of medications, particularly for patients with more severe frailty. This study reviews the evidence on the use of commonly prescribed pharmacological treatments in advanced frailty based on a questionnaire of prescribing practices and attitudes of healthcare professionals at different stages in their careers, in different countries. A convenience sample of those attending hospital grand rounds in Ireland, Canada and Australia/New Zealand (ANZ) were surveyed on the management of 18 medications in advanced frailty using a clinical vignette (man with severe dementia, Clinical Frailty Scale 7/9). Choices were to continue or discontinue (stop now or later) medications. In total, 298 respondents from Ireland (n = 124), Canada (n = 110), and ANZ (n = 64) completed the questionnaire, response rate 97%, including 81 consultants, 40 non-consultant hospital doctors, 134 general practitioners and 43 others (nurses, pharmacists, and medical students). Most felt that statins (88%), bisphosphonates (77%) and cholinesterase inhibitors (76%) should be discontinued. Thyroid replacement (88%), laxatives (83%) and paracetamol (81%) were most often continued. Respondents with experience in geriatric, palliative and dementia care were significantly more likely to discontinue medications. Age, gender and experience working in nursing homes did not contribute to the decision. Reflecting the current literature, there was no clear consensus on inappropriate prescribing, although respondents preferentially discontinued medications for secondary prevention. Experience significantly predicted the number and type discontinued, suggesting that education is important in reducing inappropriate prescribing for people in advanced states of frailty.

Effect of Visit-to-Visit Blood Pressure Variability on Cognitive and Functional Decline in Mild to Moderate Alzheimer's Disease.

BACKGROUND: Visit-to-visit blood pressure (BP) variability (VVV) is increasingly recognized as a marker of cardiovascular risk. Although implicated in cognitive decline, few studies are currently available assessing its effects on established dementia. OBJECTIVE: To investigate if VVV is associated with one-year rate of decline in measures of cognition and function in patients with mild to moderate Alzheimer's disease (AD) in the Doxycycline And Rifampicin for Alzheimer's Disease study. METHODS: Patients were included if ≥3 BP readings were available (n = 392). VVV was defined using different approaches including the coefficient of variation (CV) in BP readings between visits. Outcomes included rates of decline in the Standardized Alzheimer's Disease Assessment Scale-Cognitive Subscale (SADAS-cog), Standardized MMSE, Clinical Dementia Rating Scale, the Quick Mild Cognitive Impairment screen and the Lawton-Brody activities of daily living (ADL) scale. RESULTS: Half of the patients (196/392) had a ≥4-point decline in the SADAS-cog over one-year. Using this cut-off, there were no statistically significant associations between any measures of VVV, for systolic or diastolic BP, with and without adjustment for potential confounders including treatment allocation, history of hypertension and use of anti-hypertensive and cognitive enhancing medications. Multiple regression models examining the association between systolic BP CV by quartile and decline over one-year likewise showed no clinically significant effects, apart from a U-shaped pattern of ADL decline of borderline clinical significance.∥Conclusions: This observational study does not support recent research showing that VVV predicts cognitive decline in AD. Further studies are needed to clarify its effects on ADL in AD.

Screening for cognitive impairment in an Australian aged care assessment team as part of comprehensive geriatric assessment.

Accurate detection of mild cognitive impairment (MCI) is important to stratify and address risk. Yet, few short cognitive screening instruments are validated for this. . In Australia, all clients referred to an Aged Care Assessment Team (ACAT) receive comprehensive geriatric assessment (CGA) including the Standardized Mini-Mental State Examination (SMMSE). We compared the accuracy of the quick mild cognitive impairment (Qmci) screen to the SMMSE in 283 participants: 195 with dementia, 47 with MCI, and 41 with subjective cognitive decline (SCD) in an Australian community-based ACAT. Both had similar accuracy in identifying dementia, AUC of 0.86 for the Qmci versus 0.93 for the SMMSE (p = 0.10), but the Qmci was more accurate than the SMMSE in differentiating MCI from SCD, AUC of 0.84 versus 0.71, respectively, p = 0.046. These suggest that the new, short (3-5 min) Qmci screenis appropriate for use in an ACAT or other units conducting CGA.
