RESUMO

The impact of aerobic exercise training (AET) on cerebral blood flow (CBF) regulation remains inconclusive. This study investigated the effects of one-year progressive, moderate-to-vigorous AET on CBF, central arterial stiffness, and cognitive performance in cognitively normal older adults. Seventy-three older adults were randomly assigned to AET or stretching-and-toning (SAT, active control) intervention. CBF was measured with 2D duplex ultrasonography. Central arterial stiffness, measured by carotid ß-stiffness index, was assessed with the ultrasonography and applanation tonometry. Cerebrovascular resistance (CVR) was calculated as mean arterial pressure divided by CBF. A cognitive battery was administered with a focus on memory and executive function. Cardiorespiratory fitness was measured by peak oxygen consumption (V˙O2peak). One-year AET increased V˙O2peak and CBF and decreased CVR and carotid ß-stiffness index. In the AET group, improved V˙O2peak was correlated with increased CBF (r = 0.621, p = 0.001) and decreased CVR (r = -0.412, p = 0.037) and carotid ß-stiffness index (r = -0.478, p = 0.011). Further, increased Woodcock-Johnson recall score was associated with decreased CVR (r = -0.483, p = 0.012) and carotid ß-stiffness index (r = -0.498, p = 0.008) in AET group (not in SAT group). In conclusion, one-year progressive, moderate-to-vigorous aerobic exercise training increased CBF and decreased carotid arterial stiffness and CVR which were associated with improved memory function in cognitively normal older adults.

RESUMO

BACKGROUND: Current evidence is inconsistent on the benefits of aerobic exercise training for preventing or attenuating age-related cognitive decline in older adults. OBJECTIVE: To investigate the effects of a 1-year progressive, moderate-to-high intensity aerobic exercise intervention on cognitive function, brain volume, and cortical thickness in sedentary but otherwise healthy older adults. METHODS: We randomized 73 older adults to a 1-year aerobic exercise or stretching-and-toning (active control) program. The primary outcome was a cognitive composite score calculated from eight neuropsychological tests encompassing inductive reasoning, long-term and working memory, executive function, and processing speed. Secondary outcomes were brain volume and cortical thickness assessed by MRI, and cardiorespiratory fitness measured by peak oxygen uptake (VO2 ). RESULTS: One-year aerobic exercise increased peak VO2 by ∼10% (p < 0.001) while it did not change with stretching (p = 0.241). Cognitive composite scores increased in both the aerobic and stretching groups (p < 0.001 for time effect), although no group difference was observed. Total brain volume (p < 0.001) and mean cortical thickness (p = 0.001) decreased in both groups over time, while the reduction in hippocampal volume was smaller in the stretching group compared with the aerobic group (p = 0.040 for interaction). Across all participants, improvement in peak VO2 was positively correlated with increases in cognitive composite score (r = 0.282, p = 0.042) and regional cortical thickness at the inferior parietal lobe (p = 0.016). CONCLUSIONS: One-year aerobic exercise and stretching interventions improved cognitive performance but did not prevent age-related brain volume loss in sedentary healthy older adults. Cardiorespiratory fitness gain was positively correlated with cognitive performance and regional cortical thickness.

RESUMO

OBJECTIVE: To assess the feasibility and impact of integrating electronic patient-reported outcome measures (PROMs) into the routine outpatient care of patients with SLE. METHODS: We conducted a prospective cohort study, utilizing a mixed-methods sequential explanatory design, of SLE outpatients receiving rheumatology care at two academic medical centres. Participants completed electronic PROMs at enrolment and then prior to their next two routine rheumatology visits. PROM score reports were shared with patients and rheumatologists before visits. Patients and rheumatologists completed post-visit surveys evaluating the utility of PROMs in the clinical encounters. Focus groups of patients and interviews with treating rheumatologists were conducted to further explore their experience utilizing PROMs. RESULTS: A total of 105 SLE patients and 17 rheumatologists participated in the study. Patients completed PROMs in 159 of 184 encounters (86%), with 93% of surveys completed remotely. Patients reported that PROMs were 'quite a bit' or 'very' useful (55% of encounters) and beneficial to communication (55% of encounters). In contrast, physicians found PROMs useful (20%) and beneficial to communication (17%) less frequently. There was no significant change in visit length, health-related quality of life or disease activity after implementation of PROMs; however, patient satisfaction improved slightly. Qualitative analyses revealed that patients felt PROMs provided utility primarily by facilitating communication, particularly when physicians discussed the surveys. CONCLUSION: The remote capture and integration of electronic PROMs into clinical care was feasible in a diverse cohort of SLE outpatients. PROMs were useful to patients and enhanced their clinical experience primarily by facilitating communication.

RESUMO

BACKGROUND: The COVID-19 pandemic has strained healthcare systems and how best to address post-COVID health needs is uncertain. Here we describe the post-COVID symptoms of 675 patients followed up using a virtual review pathway, stratified by severity of acute COVID infection. METHODS: COVID-19 survivors completed an online/telephone questionnaire of symptoms after 12+ weeks and a chest X-ray. Dependent on findings at virtual review, patients were provided information leaflets, attended for investigations and/or were reviewed face-to-face. Outcomes were compared between patients following high-risk and low-risk admissions for COVID pneumonia, and community referrals. RESULTS: Patients reviewed after hospitalisation for COVID pneumonia had a median of two ongoing physical health symptoms post-COVID. The most common was fatigue (50.3% of high-risk patients). Symptom burden did not vary significantly by severity of hospitalised COVID pneumonia but was highest in community referrals. Symptoms suggestive of depression, anxiety and post-traumatic stress disorder were common (depression occurred in 24.9% of high-risk patients). Asynchronous virtual review facilitated triage of patients at highest need of face-to-face review. CONCLUSION: Many patients continue to have a significant burden of post-COVID symptoms irrespective of severity of initial pneumonia. How best to assess and manage long COVID will be of major importance over the next few years.

RESUMO

A 30-year-old primigravida with no known comorbidities presented to the emergency department at 29+6/40 gestation, with breathlessness. The initial diagnosis was pulmonary embolism, which was later revised following initial investigations and considered to be pre-eclampsia/HELLP (haemolysis, elevated liver enzymes, low platelets) syndrome. Following caesarean section and delivery of a live baby, the patient had episodes of cyanotic hypoxia and was admitted to intensive care. A provisional diagnosis of idiopathic pulmonary hypertension was performed. Decompensation led to transfer to a specialist intensive care unit for extracorporeal membrane oxygenation, where a diagnosis of patent ductus arteriosus and Eisenmenger's syndrome was made. Heart disease is the leading indirect cause of maternal death, and Eisenmenger's syndrome in pregnancy carries a 50-65% mortality. A literature review demonstrated that this is the only reported case of a postnatal diagnosis of Eisenmenger's syndrome. We considered missed opportunities to make an earlier diagnosis, so that patients and doctors will benefit from the lessons we learnt.

RESUMO

Salford Royal Hospital is one of the largest users of IVIG for chronic neurological illnesses within the UK. The majority of patients are being treated for chronic inflammatory polyneuropathy and multifocal motor neuropathy. We hypothesised that the components of care being delivered to these patients differed to our stated standard of care (IVIG care bundle). We performed a service review exercise to identify shortcomings and improve quality of patient care. The aim was to measure overall bundle compliance being delivered to 75 patients with a view to improving the overall quality of care being delivered in the future. A retrospective case note study was carried out to measure compliance with the 17 areas of care, which constituted the IVIG bundle. Nine areas of care were being delivered to all 75 patients. This meant that all patients were receiving three monthly bloods, a documented cannula pathway, a filed prescription, a medical assessment, and the correct follow-up. Not all patients had a filed consent form, ECG or HAT assessment and an even smaller number of patients had a documented calculation for the amount of IVIG that needed to be given and few had a serum save. No patient in the group was receiving the intended complete bundle of care. The results led to the development of an electronic treatment dashboard for the delivery of chronic IVIG therapy to this group. A re-audit has shown that rates of individual areas of care being delivered has increased markedly but overall compliance has only increased a slightly due to a lack of serum saves for patients.
