In this study, we evaluated the clinical outcomes associated with the use of highly bioavailable oral antibiotics (fluoroquinolones and trimethoprim-sulfamethoxazole) compared with the less-bioavailable oral antibiotics (β-lactams) in gram-negative bloodstream infections (BSIs). Among hospitalized older adult patients in Ontario, Canada, discharged home on oral treatment for gram-negative BSI between 1 January 2017 and 31 December 2019, we used a matched cohort design to compare outcomes among those receiving highly versus less-bioavailable agents; hard-matching 1:1 on sex, BSI pathogen (Escherichia coli vs. non– E. coli), and infection source (urinary vs. non-urinary/unknown source) along with a propensity score, incorporating specific pathogen, patient, and infection characteristics. The primary outcome was the composite of 90-day all-cause mortality, recurrent BSI with the same pathogen (genus and species), and re-admission to any Ontario hospital. A total of 2012 patients were included in the study (1006 in each bioavailability category). Those who received highly (compared with less) bioavailable antibiotics at discharge had lower rates of the composite outcome (171/1006 [17.0%] vs. 216/1006 [21.5%]), adjusted odds ratio being 0.74 (95% CI, 0.60–0.92). Recurrent BSI at 90 days was the main driver for the composite outcome occurring in 64 (5.4%) and 107 (9.4%) patients of the highly and less-bioavailable groups, respectively (p < 0.001) (adjusted odds ratio, 0.56; 95% CI, 0.40–0.78). Use of highly (compared with less) bioavailable antibiotics at discharge was associated with significantly better clinical outcomes among patients with gram-negative BSIs. [ABSTRACT FROM AUTHOR]

Background: Osteoarthritis (OA) high disability rate will increase as people getting older, and is the most prevalent form of arthritis in the future. This study identified the clinical effects of optimum doses of tanezumab for patients with OA. Method: Three electronic databases were searched up until January 15, 2021. The mean difference (MD) or odds ratio (OR) was considered an effect measure. The design-by-treatment interaction model was adopted for network meta-analyses. Analyses were conducted using WinBUGS 1.4.3 and R 4.0.5 software. Results: nine publications with 10 studies were included. Compared with placebo in network meta-analysis, except the outcomes of Western Ontario and McMaster Universities Osteoarthritis (WOMAC) stiffness subscale and joints replaced, all dosages of tanezumab in the other effectiveness outcome were superior to placebo, and the difference was statistically significant. However, there was no statistical difference among all different doses of tanezumab. Compared with placebo, except the outcomes of adverse events (AEs) and AEs of abnormal peripheral sensation, all different dosages of tanezumab weren't superior to placebo in the other effectiveness outcome, and the difference was statistically significant. The 10 mg of tanezumab with highest SUCRA had the best effect, but it was associated with a higher safety event. Compared with placebo, except the outcomes of WOMAC stiffness subscale and joints replaced, all dosages of tanezumab in the other effectiveness outcome were superior to placebo, and the difference was statistically significant. Compared with placebo, except for the outcomes of AEs and AEs of abnormal peripheral sensation, all dosages of tanezumab in the other effectiveness outcome were superior to placebo, and the difference was statistically significant. Other direct comparisons showed no statistical difference. Conclusion: This study recommended that clinicians should give priority to the treatment of OA patients with a low dose of 2.5 mg according to the patient's condition and actual situation. If the effect using tanezumab with 2.5 mg is not satisfactory, the increase up to 10 mg should be carefully pondered, because of a more unbalanced risk/benefit ratio. [ABSTRACT FROM AUTHOR]

Background: To evaluate the impact of integrating diabetes education teams in primary care on glycemic control, lipid, and blood-pressure management in type 2 diabetes patients. Methods: A historical cohort design was used to assess the integration of teams comprising nurse and dietitian educators in 11 Ontario primary-care sites, which delivered individualized self-management education. Of the 771 adult patients with A1C ≥ 7% recruited, 487 patients attended appointments with the diabetes teams, while the remaining 284 patients did not. The intervention's primary goal was to increase the proportion of patients with A1C ≤7%. Secondary goals were to reduce mean A1C, low-density lipoprotein, total cholesterol-high density lipoprotein, and diastolic and systolic blood pressure, as recommended by clinical-practice guidelines. Results: After 12 months, a higher proportion of intervention-group patients reached the target for A1C, compared with the control group. Mean A1C levels fell significantly among all patients, but the mean reduction was larger for the intervention group than the control group. Although more intervention-group patients reached targets for all clinical outcomes, the between-group differences were not statistically significant, except for A1C. Conclusions: Nurse and dietitian diabetes-education teams can have a clinically meaningful impact on patients' ability to meet recommended A1C targets. Given the study's historical cohort design, results are generalizable and applicable to day-to-day primary-care practice. Longer follow-up studies are needed to investigate whether the positive outcomes of the intervention are sustainable. [ABSTRACT FROM AUTHOR]

Background: The Western Ontario Rotator Cuff Index (WORC) is commonly used in orthopedic research to assess the effect of a rotator cuff injury. Questions in the WORC are presented in a visual analog scale format, which requires patients to place a pencil mark along a 10-cm line indicating their responses. The purpose of our study was to determine if a computerized version of a visual analog scale requiring patients drag a cursor along a line was comparable to data collected using the standard paper version of the WORC. Materials and methods: Administration of the WORC was randomized, with the first version given in the waiting room before the office visit, and the second immediately after the office visit, to ensure the participant''s shoulder function had not significantly changed. Results: Thirty-five patients with rotator cuff injury completed the paper and computerized versions of the WORC. There was no significant difference in mean scores for the WORC between the paper (1040.3) and computerized versions (1021.2, P = .488). The intraclass correlation coefficient for the 2 versions was 0.94. Similarly, there were no significant differences in scores between the subset of scores within the WORC (Physical Activity, Work, Sports, Lifestyle, and Emotion, P > .05), and each subset was highly correlated (intraclass correlation coefficient >0.80). Conclusions: There was no significant difference in scores for the WORC index when administered in a computerized format vs a paper format. [Copyright &y& Elsevier]

Objectives: To evaluate the impact of an Integrated Care Pathway (ICP) within a collaborative care framework for anxiety, depression and mild cognitive impairment (MCI) on clinical outcomes, quality of life, and time to treatment initiation., Design: Prospective Cohort study., Setting: Primary care practices in Toronto and Hamilton, Ontario, Canada., Participants: Patients of participating primary care practices born in the years 1950 to 1958., Sample Size: Target 150 participants, 75 in ICP and 75 in Treatment-As-Usual (TAU) arm., Intervention: ICP within a collaborative care framework and TAU., Methods and Results: One hundred forty-five participants with anxiety, depression or MCI, from five primary care practices were enrolled: 69 were managed as per ICP and 76 as per TAU. All underwent outcome assessments at 6, 12, 18, and 24 months. Compared to TAU, ICP participants had a significantly higher rate of improvement in depression symptoms (β = -0.620, F (1, 256) = 4.10, p = 0.044), anxiety symptoms (β = -0.593, F (1, 223) = 4.00, p = 0.047), and quality of life (β = 1.351, F(1, 358) = 6.58, p = 0.011). The ICP group had also a significantly higher "hazard" of treatment initiation (HR = 3.557; 95% CI: [2.228, 5.678]; p < 0.001) after controlling for age, gender and baseline severity of symptoms compared to TAU group., Conclusions: Use of an ICP within a collaborative care framework in primary care settings for anxiety, depression and MCI among older adults, results in faster reductions in clinical symptoms and improvement in quality of life compared to usual care, as well as faster access to recommended treatments., (Copyright © 2022 American Association for Geriatric Psychiatry.

Surgical repair of transverse aortic arch aneurysms frequently employ hypothermia and antegrade cerebral perfusion as protective strategies during circulatory arrest. However, prolonged mesenteric and lower limb ischemia can lead to significant lactic acidosis and end organ dysfunction, which remains a significant cause of post-operative morbidity and mortality. We report our experience with additive warm mesenteric and lower body perfusion (1-3 L/min, 30°C) in addition to continuous cerebral and myocardial perfusion in 5 patients who underwent total aortic arch replacement with trifurcated head vessel re-implantation and distal elephant trunk reconstruction. Concomitant surgical procedures included re-operations (2), aortic root operations (2), coronary artery bypass (2) and descending thoracic aortic replacement (1). Serum lactate levels demonstrated a rapid decline from a peak 9.9±2.6 post circulatory arrest to 3.4±2.0 in the intensive care unit (ICU). The lowest serum bicarbonate levels were 19.3±3.5 mmol/L, intra-operatively, which normalized to 28.4±2.4 mmol/L on return to the ICU. The lowest pH levels were 7.25±0.10, corrected to 7.43±0.04 on return to the ICU. Mean cardiopulmonary bypass and aortic cross-clamp times were 361±104 and 253±85 minutes, respectively. Mean cerebral and lower body circulatory arrest times were 0 (0) and 50±35 minutes, respectively. The mean time required for systemic rewarming was 95±66 minutes. There were no in-hospital mortalities and no patient experienced any neurological, mesenteric, renal or lower limb ischemic complications. Two patients required mechanical ventilation >24 hours, and one patient returned for reoperation for bleeding. Median intensive care unit and total hospital lengths of stay were 5 and 16 days, respectively. Our results suggest early serum lactate clearance, normalization of acidosis, and metabolic recovery when utilizing a simultaneous cerebral perfusion and warm body protection strategy for complex aortic arch surgery. This additive perfusion strategy may attenuate visceral and lower body ischemia that normally develops during periods of deep hypothermic circulatory arrest. [ABSTRACT FROM PUBLISHER]

Background: Rates of total knee arthroplasty (TKA) procedures in younger, more medically complex patients have dramatically increased over the last several decades. No study has examined categorization of lower and higher functioning subgroups within the TKA patient population. Our study aimed to determine preoperative characteristics of younger patients who are lower functioning following TKA.Methods: Patients were categorized into higher and lower functioning subgroups defined using a median split of 1) postoperative Timed Up and Go (TUG) test times and 2) Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) physical function subscale scores. A split in age (65 years) was used to further classify patients into four categories: younger lower functioning, younger higher functioning, older lower functioning and older higher functioning. Measures from preoperative domains of health, psychological, physical performance and pain severity were examined for between-group differences.Results: Comparing mean values, the younger lower functioning subgroup using the TUG had significantly weaker knee extensor, slower gait speed, higher body mass index and greater pain compared to other subgroups. The younger lower functioning subgroup using the WOMAC physical function subscale demonstrated higher pain levels and Coping Strategies Questionnaire-Catastrophizing Subscale scores compared to the older lower functioning subgroup.Conclusions: Poorer preoperative physical performance and pain severity appear to have the largest influence on early postoperative TKA recovery in younger lower functioning patients relative to both younger and older higher functioning patients.

Background: Body mass index (BMI) has been associated variably with head and neck cancer outcomes. We evaluated the association between BMI at either diagnosis or at early adulthood head and neck cancer outcomes., Methods: Patients with invasive head and neck squamous cell cancer at Princess Margaret Cancer Centre in Toronto, Canada, were surveyed on tobacco and alcohol exposure, performance status, comorbidities, and BMI at diagnosis. A subset also had data collected for BMI at early adulthood., Results: With a median follow-up of 2.5 years, in 1279 analyzed patients, being overweight (hazard ratio [HR], 0.55; 95% confidence interval [CI], 0.4-0.8; p = .001) at diagnosis was associated with improved survival when compared with individuals with normal weight. In contrast, underweight patients at diagnosis were associated with a worse outcome (HR, 1.89; 95% CI, 1.2-3.1; p < .01)., Conclusion: Being underweight at diagnosis was an independent, adverse prognostic factor, whereas being overweight conferred better prognosis. BMI in early adulthood was not associated strongly with head and neck cancer outcomes. © 2017 Wiley Periodicals, Inc. Head Neck 39: 1226-1233, 2017., (© 2017 Wiley Periodicals, Inc.)

Background: Dialysis-requiring acute kidney injury (AKI) is common among critically ill patients, but little is known about trends in the incidence and outcomes of this condition over time., Study Design: Population-based cohort study., Setting & Participants: All adult patients admitted to an intensive care unit in Ontario, Canada, 1996 to 2010., Predictor: Year and era (1996-2000, 2001-2005, and 2006-2010) of cohort entry., Outcomes: Mortality and dialysis dependence, each evaluated at 90 and 365 days after initiation of dialysis therapy for AKI., Measurements: The annual incidence proportion of dialysis-requiring AKI was evaluated and patients with this condition were characterized by era. Associations between era and the outcomes of interest were evaluated with Cox proportional hazards (for time to death) and logistic regression (for dialysis dependence), with adjustment for relevant demographic and clinical variables., Results: The annual incidence of dialysis-requiring AKI among critically ill patients increased from 0.8% in 1996 to 3.0% in 2010 (P for trend < 0.001). 90-day mortality declined from 50% in 1996 to 2000 to 45% in 2006 to 2010 (adjusted HR, 0.83 [95% CI, 0.79-0.87] compared to 1996-2000). Dialysis dependence among surviving patients at 90 days was marginally lower in 2006 to 2010 (25.1%) compared to 1996 to 2000 (27.2%), but after adjustment for confounding factors, was not significantly different (adjusted OR, 0.91; 95% CI, 0.80-1.03)., Limitations: Unmeasured confounding by factors that may have changed in patients with dialysis-requiring AKI during the different eras; data set does not allow for mechanistic explanation for the findings; and lack of access to laboratory investigations after hospital discharge., Conclusions: The incidence proportion of dialysis-requiring AKI among critically ill patients increased by almost 4-fold between 1996 and 2010. This was accompanied by a significant decline in mortality, but the risk of long-term dialysis dependence continues to affect a substantial minority of surviving patients with no clear evidence of improvement over time., (Copyright © 2015 National Kidney Foundation, Inc.
