RESUMO

The reemergence of the highly pathogenic avian influenza virus (HPAIV) subtype H5N1 in the United Kingdom in 2021-2022 has caused unprecedented epizootic events in wild birds and poultry. During the summer of 2022, there was a shift in virus transmission dynamics resulting in increased HPAIV infection in seabirds, and consequently, a profound impact on seabird populations. To understand the pathological impact of HPAIV in seabirds, we evaluated the virus antigen distribution and associated pathological changes in the tissues of great skua (Stercorarius skua, n = 8), long-tailed skua (Stercorarius longicaudus, n = 1), European herring gull (Larus argentatus, n = 5), and black-headed gull (Chroicocephalus ridibundus, n = 4), which succumbed to natural infection of HPAIV during the summer of 2022. Cases were collected from Shetland, including Scatness (mainland), No Ness (mainland), Clumlie (mainland), Hermaness (island), Fair Isle (island), Noss (island), and the West Midlands, South East, and South West of England. Grossly, gizzard ulceration was observed in one great skua and pancreatic necrosis was observed in 4 herring gulls, with intralesional viral antigen detected subsequently. Microscopical analysis revealed neuro-, pneumo-, lymphoid-, and cardiomyotropism of HPAIV H5N1, with the most common virus-associated pathological changes being pancreatic and splenic necrosis. Examination of the reproductive tract of the great skua revealed HPAIV-associated oophoritis and salpingitis, and virus replication within the oviductal epithelium. The emergence of HPAIV in seabirds Stercorariidae and Laridae, particularly during summer 2022, has challenged the dogma of HPAIV dynamics, posing a significant threat to wild bird life with potential implications for the reproductive performance of seabirds of conservation importance.

RESUMO

The National Institutes of Health (NIH) supports 24 IDeA Networks of Biomedical Research Excellence (INBRE) Programs that help develop university-based biomedical research capacity in states that historically receive low levels of extramural grant support. To assess the effectiveness of the Arkansas INBRE in meeting its biomedical research capacity-building goals, we evaluated how the context (i.e., local and institutional settings) at two undergraduate institutions impacted variability in science faculty use of program resources. Data were collected by in-depth interviews with faculty and administrators (N = 9), focused observations, a review of Arkansas INBRE databases, and internet searches. Content analysis was used to code interview transcripts and field notes, and then qualitative data were integrated with data from databases and internet searches to construct two institutional case summaries. Constant comparison was used to identify similarities and differences between the institutions that helped to explain variability in how frequently faculty used Arkansas INBRE resources, including an enrollment crisis at undergraduate institutions in the United States and the presence or absence of a robust research culture at each institution. These findings were used to suggest program improvements (e.g., classroom-based research) that could further strengthen biomedical research capacity in Arkansas. As some barriers to program effectiveness are likely found in other IDeA-eligible states, improvements suggested for the Arkansas INBRE could apply to INBRE programs elsewhere.NEW & NOTEWORTHY This article describes results from an approach to program evaluation (i.e., focused ethnography) that has not been previously used to evaluate grant mechanisms. This "experience near" approach, which involved qualitative interviews and firsthand observations, lent valuable insights into how broader and institutional contexts at two primarily undergraduate institutions hindered or facilitated use of Arkansas INBRE resources. The insights gained can be used to enhance the Arkansas INBRE, which aims to strengthen the statewide biomedical infrastructure.

RESUMO

OBJECTIVES: To investigate whether the effect of a flexible ICU visiting policy that includes flexible visitation plus visitor education on anxiety symptoms of family members is mediated by satisfaction and involvement in patient care. DESIGN: We embedded a multivariable path mediation analysis within a cluster-randomized crossover trial as a secondary analysis of The ICU Visits Study (ClinicalTrials.gov number: NCT02932358). SETTING: Thirty-six medical-surgical ICUs in Brazil. PATIENTS: Closest relatives of adult ICU patients. INTERVENTIONS: Flexible visitation (12 hr/d) supported by family education or usual restricted visitation (median, 1.5 hr/d). MEASUREMENTS AND MAIN RESULTS: Overall, 863 family members were assessed (mean age, 44.7 yr; women, 70.1%). Compared with the restricted visitation (n = 436), flexible visitation (n = 427) resulted in better mean anxiety scores (6.1 vs 7.8; mean difference, -1.78 [95% CI, -2.31 to -1.22]), as well as higher standardized scores of satisfaction (67% [95% CI, 55-79]) and involvement in patient care (77% [95% CI, 64-89]). The mediated effect of flexible visitation on mean anxiety scores through each incremental sd of satisfaction and involvement in patient care were -0.47 (95% CI, -0.68 to -0.24) and 0.29 (95% CI, 0.04-0.54), respectively. Upon exploratory analyses, emotional support, helping the ICU staff to understand patient needs, helping the patient to interpret ICU staff instructions, and patient reorientation were the domains of involvement in patient care associated with increased anxiety. CONCLUSIONS: A flexible ICU visiting policy reduces anxiety symptoms among family members and appears to work by increasing satisfaction. However, increased participation in some activities of patient care as a result of flexible visitation was associated with higher severity of anxiety symptoms.

RESUMO

OBJECTIVES: To identify the frequency, causes, and risk factors of early and late mortality among general adult patients discharged from ICUs. DESIGN: Multicenter, prospective cohort study. SETTING: ICUs of 10 tertiary hospitals in Brazil. PATIENTS: One-thousand five-hundred fifty-four adult ICU survivors with an ICU stay greater than 72 hours for medical and emergency surgical admissions or greater than 120 hours for elective surgical admissions. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The main outcomes were early (30 d) and late (31 to 365 d) mortality. Causes of death were extracted from death certificates and medical records. Twelve-month cumulative mortality was 28.2% (439 deaths). The frequency of early mortality was 7.9% (123 deaths), and the frequency of late mortality was 22.3% (316 deaths). Infections were the leading cause of death in both early (47.2%) and late (36.4%) periods. Multivariable analysis identified age greater than or equal to 65 years (hazard ratio, 1.65; p = 0.01), pre-ICU high comorbidity (hazard ratio, 1.59; p = 0.02), pre-ICU physical dependence (hazard ratio, 2.29; p < 0.001), risk of death at ICU admission (hazard ratio per 1% increase, 1.008; p = 0.03), ICU-acquired infections (hazard ratio, 2.25; p < 0.001), and ICU readmission (hazard ratio, 3.76; p < 0.001) as risk factors for early mortality. Age greater than or equal to 65 years (hazard ratio, 1.30; p = 0.03), pre-ICU high comorbidity (hazard ratio, 2.28; p < 0.001), pre-ICU physical dependence (hazard ratio, 2.00; p < 0.001), risk of death at ICU admission (hazard ratio per 1% increase, 1.010; p < 0.001), and ICU readmission (hazard ratios, 4.10, 4.17, and 1.82 for death between 31 and 60 days, 61 and 90 days, and greater than 90 days after ICU discharge, respectively; p < 0.001 for all comparisons) were associated with late mortality. CONCLUSIONS: Infections are the main cause of death after ICU discharge. Older age, pre-ICU comorbidities, pre-ICU physical dependence, severity of illness at ICU admission, and ICU readmission are associated with increased risk of early and late mortality, while ICU-acquired infections are associated with increased risk of early mortality.

RESUMO

BACKGROUND: As more patients are surviving intensive care, mental health concerns in survivors have become a research priority. Among these, post-traumatic stress disorder (PTSD) can have an important impact on the quality of life of critical care survivors. However, data on its burden are conflicting. Therefore, this systematic review and meta-analysis aimed to evaluate the prevalence of PTSD symptoms in adult critical care patients after intensive care unit (ICU) discharge. METHODS: We searched MEDLINE, EMBASE, LILACS, Web of Science, PsycNET, and Scopus databases from inception to September 2018. We included observational studies assessing the prevalence of PTSD symptoms in adult critical care survivors. Two reviewers independently screened studies and extracted data. Studies were meta-analyzed using a random-effects model to estimate PTSD symptom prevalence at different time points, also estimating confidence and prediction intervals. Subgroup and meta-regression analyses were performed to explore heterogeneity. Risk of bias was assessed using the Joanna Briggs Institute tool and the GRADE approach. RESULTS: Of 13,267 studies retrieved, 48 were included in this review. Overall prevalence of PTSD symptoms was 19.83% (95% confidence interval [CI], 16.72-23.13; I2 = 90%, low quality of evidence). Prevalence varied widely across studies, with a wide range of expected prevalence (from 3.70 to 43.73% in 95% of settings). Point prevalence estimates were 15.93% (95% CI, 11.15-21.35; I2 = 90%; 17 studies), 16.80% (95% CI, 13.74-20.09; I2 = 66%; 13 studies), 18.96% (95% CI, 14.28-24.12; I2 = 92%; 13 studies), and 20.21% (95% CI, 13.79-27.44; I2 = 58%; 7 studies) at 3, 6, 12, and > 12 months after discharge, respectively. CONCLUSION: PTSD symptoms may affect 1 in every 5 adult critical care survivors, with a high expected prevalence 12 months after discharge. ICU survivors should be screened for PTSD symptoms and cared for accordingly, given the potential negative impact of PTSD on quality of life. In addition, action should be taken to further explore the causal relationship between ICU stay and PTSD, as well as to propose early measures to prevent PTSD in this population.

RESUMO

Importance: The effects of intensive care unit (ICU) visiting hours remain uncertain. Objective: To determine whether a flexible family visitation policy in the ICU reduces the incidence of delirium. Design, Setting and Participants: Cluster-crossover randomized clinical trial involving patients, family members, and clinicians from 36 adult ICUs with restricted visiting hours (<4.5 hours per day) in Brazil. Participants were recruited from April 2017 to June 2018, with follow-up until July 2018. Interventions: Flexible visitation (up to 12 hours per day) supported by family education (n = 837 patients, 652 family members, and 435 clinicians) or usual restricted visitation (median, 1.5 hours per day; n = 848 patients, 643 family members, and 391 clinicians). Nineteen ICUs started with flexible visitation, and 17 started with restricted visitation. Main Outcomes and Measures: Primary outcome was incidence of delirium during ICU stay, assessed using the CAM-ICU. Secondary outcomes included ICU-acquired infections for patients; symptoms of anxiety and depression assessed using the HADS (range, 0 [best] to 21 [worst]) for family members; and burnout for ICU staff (Maslach Burnout Inventory). Results: Among 1685 patients, 1295 family members, and 826 clinicians enrolled, 1685 patients (100%) (mean age, 58.5 years; 47.2% women), 1060 family members (81.8%) (mean age, 45.2 years; 70.3% women), and 737 clinicians (89.2%) (mean age, 35.5 years; 72.9% women) completed the trial. The mean daily duration of visits was significantly higher with flexible visitation (4.8 vs 1.4 hours; adjusted difference, 3.4 hours [95% CI, 2.8 to 3.9]; P < .001). The incidence of delirium during ICU stay was not significantly different between flexible and restricted visitation (18.9% vs 20.1%; adjusted difference, -1.7% [95% CI, -6.1% to 2.7%]; P = .44). Among 9 prespecified secondary outcomes, 6 did not differ significantly between flexible and restricted visitation, including ICU-acquired infections (3.7% vs 4.5%; adjusted difference, -0.8% [95% CI, -2.1% to 1.0%]; P = .38) and staff burnout (22.0% vs 24.8%; adjusted difference, -3.8% [95% CI, -4.8% to 12.5%]; P = .36). For family members, median anxiety (6.0 vs 7.0; adjusted difference, -1.6 [95% CI, -2.3 to -0.9]; P < .001) and depression scores (4.0 vs 5.0; adjusted difference, -1.2 [95% CI, -2.0 to -0.4]; P = .003) were significantly better with flexible visitation. Conclusions and Relevance: Among patients in the ICU, a flexible family visitation policy, vs standard restricted visiting hours, did not significantly reduce the incidence of delirium.

RESUMO

OBJECTIVES: To synthesize data on outcomes related to patients, family members, and ICU professionals by comparing flexible versus restrictive visiting policies in ICUs. DATA SOURCES: Medline, Scopus, and Web of Science. STUDY SELECTION: Observational and randomized studies comparing flexible versus restrictive visiting policies in the ICU and evaluating at least one patient-, family member-, or ICU staff-related outcome. DATA EXTRACTION: Duplicate independent review and data abstraction. DATA SYNTHESIS: Of 16 studies identified for inclusion, seven were meta-analyzed. Most studies were rated as having a moderate risk of bias. Among patients, flexible visiting policies were associated with reduced frequency of delirium (odds ratio, 0.39; 95% CI, 0.22-0.69; I = 0%) and lower severity of anxiety symptoms (mean difference, -2.20; 95% CI, -3.80 to -0.61; I = 71%). Flexible visiting policies were not associated with increased risk of ICU mortality (odds ratio, 0.71; 95% CI, 0.38-1.36; I = 86%), ICU-acquired infections (odds ratio, 0.98; 95% CI, 0.68-1.42; I = 11%), or longer ICU stay (mean difference, -0.26 d; 95% CI, -0.57 to 0.05; I = 54%). Among family members, flexible visiting policies were associated with greater satisfaction. Among ICU professionals, flexible visiting policies were associated with higher burnout levels. CONCLUSIONS: Flexible ICU visiting hours have the potential to reduce delirium and anxiety symptoms among patients and to improve family members' satisfaction. However, they may be associated with an increased risk of burnout among ICU professionals. These conclusions are based on few studies, with small samples and moderate risk of bias.

RESUMO

BACKGROUND: Whole-body vibration (WBV) is an alternative intervention for patients with diabetic peripheral neuropathy (DPN) but its clinical efficacy is unclear. OBJECTIVE: To summarize the effects of WBV on important outcomes for patients with DPN. DATA SOURCES: Medline, PEDro, Cochrane CENTRAL and Google Scholar were searched up to July 2017. Search terms included diabetic neuropathies and WBV. STUDY SELECTION: Interventional studies that utilized WBV for treating DPN outcomes with at least one-week follow-up were included. DATA EXTRACTION: Data were independently extracted by two reviewers using a standardized checklist. DATA SYNTHESIS: Twenty-two registers were identified. Three studies (83 patients) satisfied the selection criteria. Studies assessed the effect of WBV on the glycemic profile, neuropathic pain, and balance. WBV presented positive effects on these outcomes, but a high risk of bias was identified in most studies. No study assessed plantar tactile sensitivity. LIMITATIONS: Most studies have a high level of bias. No pooling data was possible due to few studies included. CONCLUSIONS: Very low-quality evidence suggests that WBV has a slight positive effect on glycemic control in patients with DPN, improving neuropathic pain and balance. Future studies may change the WBV estimated effect on DPN outcomes.

RESUMO

The Institutional Development Award (IDeA) program, housed within the National Institute for General Medical Sciences, administers the Networks of Biomedical Research Excellence (INBRE) as a strategic mission to broaden the geographic distribution of National Institutes of Health (NIH) funding within the United States. Undergraduate summer student mentored research programs (SSMRP) are a common feature of INBRE programs and are designed to increase undergraduate student interest in research careers in the biomedical sciences. Little information is available about student perspectives on how these programs impact their choices relative to education and careers. Therefore, we conducted qualitative interviews with 20 participants from the Arkansas INBRE SSMRP in the years 2002-2012. Each telephone interview lasted 30-45 min. An interview guide with a broad "grand tour" question was used to elicit student perspectives on SSMRP participation. Interviews were digitally recorded, then transcribed verbatim, and the transcript checked for accuracy. Content analysis and constant comparison were used to identify nine themes that were grouped into three temporal categories: before, during, and after the SSMRP experience. Students viewed the experience as positive and felt it impacted their career choices. They emphasized the value of mentoring in the program, and some reported maintaining a relationship with the mentor after the summer experience ended. Students also valued learning new laboratory and presentation skills and felt their research experience was enhanced by meeting students and scientists with a wide range of career interests. These data suggest that the Arkansas INBRE and the NIH IDeA program are successfully meeting the goal of increasing interest in research among undergraduates.

RESUMO

Biochemical reaction rates are highly sensitive to temperature, and the body temperatures of ectotherms covary with their immediate environment. Therefore, ectotherms should choose microhabitats that permit the maintenance of physiological function. While some previous studies have found that squamate reptiles choose retreat sites that allow them to maintain physiologically optimal body temperatures, this research has been limited in context and taxonomic scope. We sought to test these empirical patterns by studying the properties of retreat sites in the context of physiological preferences and tolerances in a population of semifossorial ring-necked snakes (Diadophis punctatus). We measured environmental temperature distributions of retreat sites, field body temperatures, thermal preferences, and both upper voluntary temperature and critical thermal minima of snakes. We found that ring-necked snakes are under larger and warmer rocks, but that body temperatures in the field do not match thermal preferences measured in the laboratory. Specifically, we found aggregated ring-necked snakes (those occurring with multiple conspecifics) select rocks providing environmental temperatures averaging 3°C higher than their preferred temperature. By contrast, solitary snakes select rocks that allowed them to maintain their body temperatures very close to their preferred temperatures. These results imply that there is substantial within and among-species variation in the role of thermal considerations in retreat-site selection. Our work also highlights the complex tradeoffs between physiological and ecological requirements that organisms must navigate in heterogeneous habitats.

RESUMO

OBJECTIVES: To evaluate the effect of an extended visitation model compared with a restricted visitation model on the occurrence of delirium among ICU patients. DESIGN: Prospective single-center before and after study. SETTING: Thirty-one-bed medical-surgical ICU. PATIENTS: All patients greater than or equal to 18 years old with expected length of stay greater than or equal to 24 hours consecutively admitted to the ICU from May 2015 to November 2015. INTERVENTIONS: Change of visitation policy from a restricted visitation model (4.5 hr/d) to an extended visitation model (12 hr/d). MEASUREMENTS AND MAIN RESULTS: Two hundred eighty-six patients were enrolled (141 restricted visitation model, 145 extended visitation model). The primary outcome was the cumulative incidence of delirium, assessed bid using the confusion assessment method for the ICU. Predefined secondary outcomes included duration of delirium/coma; any ICU-acquired infection; ICU-acquired bloodstream infection, pneumonia, and urinary tract infection; all-cause ICU mortality; and length of ICU stay. The median duration of visits increased from 133 minutes (interquartile range, 97.7-162.0) in restricted visitation model to 245 minutes (interquartile range, 175.0-272.0) in extended visitation model (p < 0.001). Fourteen patients (9.6%) developed delirium in extended visitation model compared with 29 (20.5%) in restricted visitation model (adjusted relative risk, 0.50; 95% CI, 0.26-0.95). In comparison with restricted visitation model patients, extended visitation model patients had shorter length of delirium/coma (1.5 d [interquartile range, 1.0-3.0] vs 3.0 d [interquartile range, 2.5-5.0]; p = 0.03) and ICU stay (3.0 d [interquartile range, 2.0-4.0] vs 4.0 d [interquartile range, 2.0-6.0]; p = 0.04). The rate of ICU-acquired infections and all-cause ICU mortality did not differ significantly between the two study groups. CONCLUSIONS: In this medical-surgical ICU, an extended visitation model was associated with reduced occurrence of delirium and shorter length of delirium/coma and ICU stay.

RESUMO

Background: Gitelman syndrome (GS) is a rare recessively inherited renal tubulopathy associated with renal potassium (K) and magnesium (Mg) loss. It requires lifelong K and Mg supplementation at high doses that are at best unpalatable and at worst, intolerable. In particular, gastrointestinal side effects often limit full therapeutic usage. Methods: We report here the analysis of a cohort of 28 adult patients with genetically proven GS who attend our specialist tubular disorders clinic, in whom we initiated the use of a modified-release Mg preparation (slow-release Mg lactate) and who were surveyed by questionnaire. Results: Twenty-five patients (89%) preferred the new treatment regimen. Of these 25, 17 (68%) regarded their symptom burden as improved and seven reported no worsening. Of the 25 who were not Mg-treatment naïve, 13 (59%) patients reported fewer side effects, 7 (32%) described them as the same and only 2 (9%) considered side effects to be worse. Five were able to increase their dose without ill-effect. Overall, biochemistry improved in 91% of the 23 patients switched from therapy with other preparations who chose to continue the modified-release Mg preparation. Eleven (48%) improved both their Mg and K mean levels, 3 (13%) improved Mg levels only and in 7 cases (30%), K levels alone rose. Conclusions: Patient-reported and biochemical outcomes using modified-release Mg supplements were very favourable, and patient choice should play a large part in choosing Mg supplements with GS patients.

RESUMO

BACKGROUND AND PURPOSE: Neuromuscular electric stimulation (NMES) has been used to reduce spasticity and improve range of motion in patients with stroke. However, contradictory results have been reported by clinical trials. A systematic review of randomized clinical trials was conducted to assess the effect of treatment with NMES with or without association to another therapy on spastic muscles after stroke compared with placebo or another intervention. METHODS: We searched the following electronic databases (from inception to February 2015): Medline (PubMed), EMBASE, Cochrane Central Register of Controlled Trials and Physiotherapy Evidence Database (PEDro). Two independent reviewers assessed the eligibility of studies based on predefined inclusion criteria (application of electric stimulation on the lower or upper extremities, regardless of NMES dosage, and comparison with a control group which was not exposed to electric stimulation), excluding studies with <3 days of intervention. The primary outcome extracted was spasticity, assessed by the Modified Ashworth Scale, and the secondary outcome extracted was range of motion, assessed by Goniometer. RESULTS: Of the total of 5066 titles, 29 randomized clinical trials were included with 940 subjects. NMES provided reductions in spasticity (-0.30 [95% confidence interval, -0.58 to -0.03], n=14 randomized clinical trials) and increase in range of motion when compared with control group (2.87 [95% confidence interval, 1.18-4.56], n=13 randomized clinical trials) after stroke. CONCLUSIONS: NMES combined with other intervention modalities can be considered as a treatment option that provides improvements in spasticity and range of motion in patients after stroke.

RESUMO

The aim of this study was to investigate the effects of whole body vibration (WBV) on physiological parameters, cutaneous temperature, tactile sensitivity, and balance. Twenty-four healthy adults (25.3 ± 2.6 years) participated in four WBV sessions. They spent 15 minutes on a vibration platform in the vertical mode at four different frequencies (31, 35, 40, and 44 Hz) with 1 mm of amplitude. All variables were measured before and after WBV exposure. Pressure sensation in five anatomical regions and both feet was determined using Von Frey monofilaments. Postural sway was measured using a force plate. Cutaneous temperature was obtained with an infrared camera. WBV influences the discharge of the skin touch-pressure receptors, decreasing sensitivity at all measured frequencies and foot regions (P ≤ 0.05). Regarding balance, no differences were found after 20 minutes of WBV at frequencies of 31 and 35 Hz. At 40 and 44 Hz, participants showed higher anterior-posterior center of pressure (COP) velocity and length. The cutaneous temperature of the lower limbs decreased during and 10 minutes after WBV. WBV decreases touch-pressure sensitivity at all measured frequencies 10 min after exposure. This may be related to the impaired balance at higher frequencies since these variables have a role in maintaining postural stability. Vasoconstriction might explain the decreased lower limb temperature.

RESUMO

In recent years, commercial funding for continuing medical education (CME) has dropped significantly. Yet, little has been written about how this might affect CME in oncology, a field in which new drugs and advances emerge at a rapid pace. This study examines the role oncologists and oncology fellows say that CME plays in their ongoing professional development and their attitudes about the potential and realistic impact upon both the dissemination of medical information and the impact on patient care if commercial support were removed from CME. The study is based upon a national survey of 368 oncology clinicians (283 oncologists and 85 oncology fellows). Respondents indicated that CME is an important part of their ongoing professional development. The majority of oncologists (90%) and oncology fellows (78%) "agreed" or "strongly agreed" that commercial support may be more necessary for oncology than for other specialties due to the rate at which cancer therapies are introduced. Respondents felt loss of commercial support would impact cost, format, and availability of oncology CME programs. Half of oncologists thought eliminating commercial support for CME would have a negative impact on application of new therapies in oncology. Yet, both oncologists and oncology fellows were reluctant to claim the removal of commercial support would negatively affect the practice of evidence-based medicine, patient outcomes, or patient safety. A possible explanation of this apparent contradiction is found in the social sciences literature.

RESUMO

OBJECTIVES: To identify the prevalence and associated factors of cognitive dysfunction, 1 year after ICU discharge, among adult patients, and it´s relation with quality of life. METHODS: Multicenter, prospective cohort study including ICUs of 10 tertiary hospitals in Brazil, between May 2014 and December 2018. The patients included were 452 adult ICU survivors (median age 60; 47.6% women) with an ICU stay greater than 72 h. RESULTS: At 12 months after ICU discharge, a Montreal Cognitive Assessment (tMOCA) telephone score of less than 12 was defined as cognitive dysfunction. At 12 months, of the 452 ICU survivors who completed the cognitive evaluation 216 (47.8%) had cognitive dysfunction. In multivariable analyses, the factors associated with long-term (1-year) cognitive dysfunction were older age (Prevalence Ratio-PR = 1.44, P < 0.001), absence of higher education (PR = 2.81, P = 0.005), higher comorbidities on admission (PR = 1.089; P = 0.004) and delirium (PR = 1.13, P < 0.001). Health-related Quality of life (HRQoL), assessed by the mental and physical dimensions of the SF-12v2, was significantly better in patients without cognitive dysfunction (Mental SF-12v2 Mean difference = 2.54; CI 95%, - 4.80/- 0.28; p = 0.028 and Physical SF-12v2 Mean difference = - 2.85; CI 95%, - 5.20/- 0.50; P = 0.018). CONCLUSIONS: Delirium was found to be the main modifiable predictor of long-term cognitive dysfunction in ICU survivors. Higher education consistently reduced the probability of having long-term cognitive dysfunction. Cognitive dysfunction significantly influenced patients' quality of life, leading us to emphasize the importance of cognitive reserve for long-term prognosis after ICU discharge.

RESUMO

RATIONALE: Evidence about long-term sequelae after hospitalization for acute respiratory distress syndrome due to COVID-19 is still scarce. PURPOSE: To evaluate changes in pulmonary, cardiac, and renal function and in quality of life after hospitalization for acute respiratory distress syndrome secondary to COVID-19. METHODS: This will be a multicenter case-control study of 220 participants. Eligible are patients who are hospitalized for acute respiratory distress syndrome due to COVID-19. In the control group, individuals with no history of hospitalization in the last 12 months or long-term symptoms of COVID-19 will be selected. All individuals will be subjected to pulmonary spirometry with a carbon monoxide diffusion test, chest tomography, cardiac and renal magnetic resonance imaging with gadolinium, ergospirometry, serum and urinary creatinine, total protein, and urinary microalbuminuria, in addition to quality-of-life questionnaires. Patients will be evaluated 12 months after hospital discharge, and controls will be evaluated within 90 days of inclusion in the study. For all the statistical analyses, p < 0.05 is the threshold for significance. RESULTS: The primary outcome of the study will be the pulmonary diffusing capacity for carbon monoxide measured after 12 months. The other parameters of pulmonary, cardiac, and renal function and quality of life are secondary outcomes. CONCLUSION: This study aims to determine the long-term sequelae of pulmonary, cardiac, and renal function and the quality of life of patients hospitalized for acute respiratory distress syndrome due to COVID-19 in the Brazilian population.

RESUMO

BACKGROUND: Gitelman syndrome (GS) is a rare inherited disorder caused by mutations in SLC12A3, encoding the thiazide-sensitive transporter NCCT (sodium chloride co-transporter) in the distal tubule. It is characterized by renal potassium (K) and magnesium (Mg) wasting, relative hypotension and hypocalciuria. However, there is phenotypic variability and long-term studies are scarce. METHODS: We retrospectively assessed clinical and genetic characteristics, and electrolyte requirements, in a cohort of 36 patients with genetically proven GS. RESULTS: The 21 males and 15 females were of median age 39.5 years, range 17-66 years. Six were diagnosed in childhood. Among the 72 mutant alleles, 41 different sequence alterations were identified, of which 13 were previously unreported. Surprisingly, 44% (n = 16) of the cohort has developed hypertension (13 males, 3 females, P = 0.019; median age 53 versus 57 years, P = 0.95). One was already hypertensive by age 23 years. Currently normotensive patients were significantly younger: median 37 versus 55 years (P = 0.005). Hypertensive patients were more likely to harbour mutations in the C-terminal half of the NCCT protein (P = 0.016). Females required more K (median 128 versus 72 mmol/day; P = 0.01) but not Mg. Those with exon 26 and/or at least one destructive mutation had higher K requirements than those with neither: 108 versus 72 mmol (P = 0.016) and a tendency towards higher Mg needs: 30 versus 7.4 mmol (P = 0.07). CONCLUSIONS: Our findings suggest that the development of secondary hypertension may be an expected feature of the ageing GS population despite the obligate salt wasting that characterizes the disorder. We hypothesize that this may be related to chronic secondary hyperaldosteronism. The apparently more severe phenotype in women may be related to the effects of female sex hormones on expression or function of NCCT.

RESUMO

BACKGROUND: Neurologic assessments using a monofilament and a tuning fork are routinely performed to screen for peripheral neuropathy and to identify foot ulceration and amputation risks. We investigated whether assessments commonly used to monitor sensation in the feet may illuminate a more holistic perspective of a person's overall health status. METHODS: Recruitment of 50 participants for foot health screening was facilitated via a promotional event for Foot Health Week. Participants were aged 52 to 92 years (31 women and 19 men). Monofilament and tuning fork assessments were used to determine each participant's neurologic status. Participants also completed a modified Foot Health Status Questionnaire. Data were analyzed to identify correlations between neurologic assessment results and questionnaire responses. RESULTS: For participants self-reporting an "excellent" health rating, a significant relationship was identified with adequate vibration sensation (P < .01). Significant correlations were also identified between a greater number of sites detected using a 10-g monofilament assessment and a person's experience of having a lot of energy (P = .03), limited interference with social activities (P = .03), and greater confidence completing a variety of functional tasks. CONCLUSIONS: Significant correlations were observed between basic neurologic assessments and a participant's perception of their overall health. Although these findings reflect a correlational rather than a causational relationship, they may provide a stimulus for clinicians to reflect on the holistic value of peripheral neurologic assessment. Although the immediate focus for a practitioner is minimizing risk and preserving tissue viability, neurologic test results may be useful to stimulate further discussion about a patient's health outcomes by exploring issues beyond the presenting condition.

RESUMO

OBJECTIVE: To evaluate the impact of an educational website on satisfaction and symptoms of anxiety and depression among family members of critically ill adult patients. METHODS: We embedded an analysis of website access in a cohort study conducted in intensive care units with flexible visiting hours in Brazil. Family members were guided to access an educational website designed to help them understand the processes and emotions associated with an intensive care unit stay. Subjects were evaluated for baseline data within the first 48 hours following enrollment and outcome assessment at up to 7 days after patient discharge from the intensive care unit, death, or until the 30th day of the study. The main outcomes were satisfaction using the Critical Care Family Needs Inventory and the presence of anxiety and depression symptoms using the Hospital Anxiety and Depression Scale. RESULTS: A total of 532 family members were evaluated during the study period. Of these, 61 (11.5%) accessed the website. After adjustments, family members who accessed the website had significantly better mean Critical Care Family Needs Inventory scores (152.8 versus 145.2, p = 0.01) and a lower prevalence of probable clinical anxiety (prevalence ratio 0.35; 95%CI 0.14 - 0.89) than family members who did not access the website. There were no differences regarding symptoms of depression. CONCLUSION: Access to an educational website was associated with higher family satisfaction with care and a lower prevalence of clinical anxiety.
