RESUMO

BACKGROUND AND AIMS: Guidelines suggest similar blood pressure (BP) targets in patients with and without diabetes and recommend ambulatory BP monitoring (ABPM) to diagnose and classify hypertension. It was explored whether different levels of ambulatory and office BP and different hypertension phenotypes associate with differences of risk in diabetes and no diabetes. METHODS: This analysis assessed outcome data from the Spanish ABPM Registry in 59 124 patients with complete available data. The associations between office, mean, daytime, and nighttime ambulatory BP with the risk in patients with or without diabetes were explored. The effects of diabetes on mortality in different hypertension phenotypes, i.e. sustained hypertension, white-coat hypertension, and masked hypertension, compared with normotension were studied. Analyses were done with Cox regression analyses and adjusted for demographic and clinical confounders. RESULTS: A total of 59 124 patients were recruited from 223 primary care centres in Spain. The majority had an office systolic BP >140 mmHg (36 700 patients), and 23 128 (40.6%) patients were untreated. Diabetes was diagnosed in 11 391 patients (19.2%). Concomitant cardiovascular (CV) disease was present in 2521 patients (23.1%) with diabetes and 4616 (10.0%) without diabetes. Twenty-four-hour mean, daytime, and nighttime ambulatory BP were associated with increased risk in diabetes and no diabetes, while in office BP, there was no clear association with no differences with and without diabetes. While the relative association of BP to CV death risk was similar in diabetes compared with no diabetes (mean interaction P = .80, daytime interaction P = .97, and nighttime interaction P = .32), increased event rates occurred in diabetes for all ABPM parameters for CV death and all-cause death. White-coat hypertension was not associated with risk for CV death (hazard ratio 0.86; 95% confidence interval 0.72-1.03) and slightly reduced risk for all-cause death in no diabetes (hazard ratio 0.89; confidence interval 0.81-0.98) but without significant interaction between diabetes and no diabetes. Sustained hypertension and masked hypertension in diabetes and no diabetes were associated with even higher risk. There were no significant interactions in hypertensive phenotypes between diabetes and no diabetes and CV death risk (interaction P = .26), while some interaction was present for all-cause death (interaction P = .043) and non-CV death (interaction P = .053). CONCLUSIONS: Diabetes increased the risk for all-cause death, CV, and non-CV death at every level of office and ambulatory BP. Masked and sustained hypertension confer to the highest risk, while white-coat hypertension appears grossly neutral without interaction of relative risk between diabetes and no diabetes. These results support recommendations of international guidelines for strict BP control and using ABPM for classification and assessment of risk and control of hypertension, particularly in patients with diabetes. CLINICAL TRIAL REGISTRATION: Not applicable.

RESUMO

The Lyon Consensus provides conclusive criteria for and against the diagnosis of gastro-oesophageal reflux disease (GERD), and adjunctive metrics that consolidate or refute GERD diagnosis when primary criteria are borderline or inconclusive. An international core and working group was assembled to evaluate research since publication of the original Lyon Consensus, and to vote on statements collaboratively developed to update criteria. The Lyon Consensus 2.0 provides a modern definition of actionable GERD, where evidence from oesophageal testing supports revising, escalating or personalising GERD management for the symptomatic patient. Symptoms that have a high versus low likelihood of relationship to reflux episodes are described. Unproven versus proven GERD define diagnostic strategies and testing options. Patients with no prior GERD evidence (unproven GERD) are studied using prolonged wireless pH monitoring or catheter-based pH or pH-monitoring off antisecretory medication, while patients with conclusive GERD evidence (proven GERD) and persisting symptoms are evaluated using pH-impedance monitoring while on optimised antisecretory therapy. The major changes from the original Lyon Consensus criteria include establishment of Los Angeles grade B oesophagitis as conclusive GERD evidence, description of metrics and thresholds to be used with prolonged wireless pH monitoring, and inclusion of parameters useful in diagnosis of refractory GERD when testing is performed on antisecretory therapy in proven GERD. Criteria that have not performed well in the diagnosis of actionable GERD have been retired. Personalisation of investigation and management to each patient's unique presentation will optimise GERD diagnosis and management.

RESUMO

BACKGROUND: There are no systematic measures of central line-associated bloodstream infections (CLABSIs) in patients maintaining central venous catheters (CVCs) outside acute care hospitals. To clarify the burden of CLABSIs in these patients, we characterized patients with CLABSI present on hospital admission (POA). METHODS: Retrospective cross-sectional analysis of patients with CLABSI-POA in 3 health systems covering 11 hospitals across Maryland, Washington DC, and Missouri from November 2020 to October 2021. CLABSI-POA was defined using an adaptation of the acute care CLABSI definition. Patient demographics, clinical characteristics, and outcomes were collected via record review. Cox proportional hazard analysis was used to assess factors associated with the all-cause mortality rate within 30 days. RESULTS: A total of 461 patients were identified as having CLABSI-POA. CVCs were most commonly maintained in home infusion therapy (32.8%) or oncology clinics (31.2%). Enterobacterales were the most common etiologic agent (29.2%). Recurrent CLABSIs occurred in a quarter of patients (25%). Eleven percent of patients died during the hospital admission. Among patients with CLABSI-POA, mortality risk increased with age (hazard ratio vs age <20 years by age group: 20-44 years, 11.2 [95% confidence interval, 1.46-86.22]; 45-64 years, 20.88 [2.84-153.58]; ≥65 years, 22.50 [2.98-169.93]) and lack of insurance (2.46 [1.08-5.59]), and it decreased with CVC removal (0.57 [.39-.84]). CONCLUSIONS: CLABSI-POA is associated with significant in-hospital mortality risk. Surveillance is required to understand the burden of CLABSI in the community to identify targets for CLABSI prevention initiatives outside acute care settings.

RESUMO

The bulk of the current knowledge on atrial fibrillation (AF)-associated stroke risk and benefit of oral anticoagulation derives from studies on patients with clinically diagnosed AF. Subclinical AF (SCAF), defined as AF discovered during the interrogation of prolonged heart monitoring, is often asymptomatic and short-lasting, is associated with increased stroke risk compared with sinus rhythm, and may progress to clinical AF. Despite the extensive screening for and treatment of SCAF, especially in secondary stroke prevention, the net benefit of this practice is not established. Recent studies of SCAF have provided new insights: (1) SCAF is extremely common and may sometimes indicate physiological findings, (2) the stroke risk associated with SCAF is lower than that of clinically detected AF, and (3) any benefit on stroke risk may be countered by increased bleeding risk (no net benefit). How should we interpret the latest knowledge in the setting of poststroke AF screening and prevention?

RESUMO

BACKGROUND: In qualitative work, patients report that seemingly short trips to clinic (eg, a supposed 10-minute blood draw) often turn into "all-day affairs." We sought to quantify the time patients with cancer spend attending ambulatory appointments. METHODS: We conducted a retrospective study of patients scheduled for oncology-related ambulatory care (eg, labs, imaging, procedures, infusions, and clinician visits) at an academic cancer center over 1 week. The primary exposure was the ambulatory service type(s) (eg, clinician visit only, labs and infusion, etc.). We used Real-Time Location System badge data to calculate clinic times and estimated round-trip travel times and parking times. We calculated and summarized clinic and total (clinic + travel + parking) times for ambulatory service types. RESULTS: We included 435 patients. Across all service day type(s), the median (IQR) clinic time was 119 (78-202) minutes. The estimated median (IQR) round-trip driving distance and travel time was 34 (17-49) miles and 50 (36-68) minutes. The median (IQR) parking time was 14 (12-15) minutes. Overall, the median (IQR) total time was 197 (143-287) minutes. The median total times for specific service type(s) included: 99 minutes for lab-only, 144 minutes for clinician visit only, and 278 minutes for labs, clinician visit, and infusion. CONCLUSION: Patients often spent several hours pursuing ambulatory cancer care on a given day. Accounting for opportunity time costs and the coordination of activities around ambulatory care, these results highlight the substantial time burdens of cancer care, and support the notion that many days with ambulatory health care contact may represent "lost days."

RESUMO

Blood pressure (BP) follows a circadian rhythm intertwined with the sleep-wake cycle. Acute partial sleep deprivation (PSD; sleep ≤ 6 h) can increase BP, associated with increased cardiovascular risk. Acute exercise can reduce BP for up to 24 h, a phenomenon termed postexercise hypotension. The present study tested whether aerobic exercise could mitigate the augmented 24-h ambulatory BP caused by acute PSD. Twenty-four young otherwise healthy adults (22 ± 3 yr; 14 females; self-reported chronotypes: 6 early/10 intermediate/8 late; Pittsburgh sleep quality index: 17 good/7 poor sleepers) completed a randomized crossover trial in which, on different days, they slept normally (2300-0700), restricted sleep [0330-0700 (PSD)], and cycled for 50 min (70-80% predicted heart rate maximum) before PSD. Ambulatory BP was assessed every 30 min until 2100 the next day. Acute PSD increased 24-h systolic BP (control 117 ± 9 mmHg, PSD 122 ± 9 mmHg; P < 0.001) and prior exercise attenuated (exercise + PSD 120 ± 9 mmHg; P = 0.04 vs. PSD) but did not fully reverse this response (exercise + PSD, P = 0.02 vs. control). Subgroup analysis revealed that the 24-h systolic BP reduction following exercise was specific to late types (PSD 119 ± 7 vs. exercise + PSD 116 ± 6 mmHg; P < 0.05). Overall, habitual sleep quality was negatively correlated with the change in daytime systolic BP following PSD (r = -0.56, P < 0.01). These findings suggest that the ability of aerobic cycling exercise to counteract the hemodynamic effects of acute PSD in young adults may be dependent on chronotype and that habitual sleep quality can predict the daytime BP response to acute PSD.NEW & NOTEWORTHY We demonstrate that cycling exercise attenuates, but does not fully reverse, the augmented 24-h ambulatory blood pressure (BP) response caused by acute partial sleep deprivation (PSD). This response was primarily observed in late chronotypes. Furthermore, daytime BP after acute PSD is related to habitual sleep quality, with better sleepers being more prone to BP elevations. This suggests that habitual sleeping habits can influence BP responses to acute PSD and their interactions with prior cycling exercise.

RESUMO

BACKGROUND: Nighttime BP and BP dipping (daytime-nighttime BP) are prognostic for cardiovascular disease. Compared with other racial/ethnic groups, Black Americans exhibit elevated nighttime BP and attenuated BP dipping. Neighborhood deprivation may contribute to disparities in cardiovascular health, but its effects on resting and ambulatory BP patterns in young adults is unclear. Therefore, we examined associations between neighborhood deprivation with resting and nighttime BP and BP dipping in young Black and White adults. METHODS: We recruited 19 Black and 28 White participants (23 M/24 F, 21±1 years, body mass index: 26±4 kg/m2) for 24-hour ambulatory BP monitoring. We assessed resting BP, nighttime BP, and BP dipping (absolute dip and nighttime:daytime BP ratio). We used the area deprivation index (ADI) to assess average neighborhood deprivation during early- and mid-childhood, and adolescence. RESULTS: Compared with White participants, Black participants exhibited higher resting systolic and diastolic BP (ps≤0.029), nighttime systolic BP (114±9 vs. 108±9 mmHg, p=0.049), diastolic BP (63±8 vs. 57±7 mmHg, p=0.010), and attenuated absolute systolic BP dipping (12±5 vs. 9±7 mmHg, p=0.050). Black participants experienced greater average ADI scores compared with White participants (110(10) vs. 97(22), p=0.002), and select ADI scores correlated with resting BP and some ambulatory BP measures. Within each race, select ADI scores correlated with some BP measures for Black participants, but there were no ADI and BP correlations for White participants. CONCLUSIONS: Our findings suggest neighborhood deprivation may contribute to higher resting BP and impaired ambulatory BP patterns in young adults warranting further investigation in larger cohorts.

RESUMO

We aimed to identify the minimum number of ambulatory blood pressure (ABP) measures to accurately determine daytime and nighttime systolic blood pressure (BP) averages and nocturnal dipping status (i.e., relative daytime:nighttime change). A total of 43 midlife participants wore an ABP monitor for 24 h with measurements every 20/30 min during the daytime/nighttime, as identified by a sleep diary. We calculated daytime/nighttime systolic BP average and dipping status from all available measurements per participant (i.e., normative data). We then calculated daytime and nighttime BP per participant based on a random selection of 8-20 and 4-10 measurements and replicated random selections 1,000 times. We calculated accuracy by checking the proportion from 1,000 different randomly selected samples for a particular number of measurements that systolic BP was ±5 mmHg of normative data, and dipping status remained unchanged for each participant compared with the normative value. The best fit for the regression model estimated the minimal number of measurements for an accuracy of 95% in BP averages. For a 95% accuracy in estimating daytime and nighttime systolic BP, 11 daytime and 8 nighttime measurements were required. The highest accuracy for dipping status was 91.6 ± 13.4% using 20 daytime and 10 nighttime measures, while the lowest was (83.4 ± 15.1%) using 8 daytime and 4 nighttime measures. In midlife adults, 11 daytime and 8 nighttime measurements are likely enough to calculate average systolic BPs accurately. However, no minimum number is suggested to accurately calculate dipping status.NEW & NOTEWORTHY We found that a minimum of 11 blood pressure (BP) measures are necessary to calculate an accurate average daytime BP, and 8 nighttime measures are necessary to calculate an accurate nighttime average if 95% accuracy is acceptable. Regarding BP dipping status, the current recommendations (20 daytime/7 nighttime) inaccurately classified the dipping status 10.5% of the time, suggesting that guidelines may need to be updated to classify patients as nocturnal dippers or nondippers correctly.

RESUMO

A primary goal of neuroscience is to understand the relationship between the brain and behavior. While magnetic resonance imaging (MRI) examines brain structure and function under controlled conditions, digital phenotyping via portable automatic devices (PAD) quantifies behavior in real-world settings. Combining these two technologies may bridge the gap between brain imaging, physiology, and real-time behavior, enhancing the generalizability of laboratory and clinical findings. However, the use of MRI and data from PADs outside the MRI scanner remains underexplored. Herein, we present a Preferred Reporting Items for Systematic Reviews and Meta-Analysis systematic literature review that identifies and analyzes the current state of research on the integration of brain MRI and PADs. PubMed and Scopus were automatically searched using keywords covering various MRI techniques and PADs. Abstracts were screened to only include articles that collected MRI brain data and PAD data outside the laboratory environment. Full-text screening was then conducted to ensure included articles combined quantitative data from MRI with data from PADs, yielding 94 selected papers for a total of N = 14,778 subjects. Results were reported as cross-frequency tables between brain imaging and behavior sampling methods and patterns were identified through network analysis. Furthermore, brain maps reported in the studies were synthesized according to the measurement modalities that were used. Results demonstrate the feasibility of integrating MRI and PADs across various study designs, patient and control populations, and age groups. The majority of published literature combines functional, T1-weighted, and diffusion weighted MRI with physical activity sensors, ecological momentary assessment via PADs, and sleep. The literature further highlights specific brain regions frequently correlated with distinct MRI-PAD combinations. These combinations enable in-depth studies on how physiology, brain function and behavior influence each other. Our review highlights the potential for constructing brain-behavior models that extend beyond the scanner and into real-world contexts.

RESUMO

PURPOSE: We sought to determine if the addition of liposomal bupivacaine to bupivacaine hydrochloride improves opioid-free rate and postoperative pain scores among children undergoing ambulatory urologic surgery. MATERIALS AND METHODS: A prospective, phase 3, single-blinded, single-center randomized trial with superiority design was conducted in children 6 to 18 years undergoing ambulatory urologic procedures between October 2021 and April 2023. Patients were randomized 1:1 to receive dorsal penile nerve block (penile procedures) or incisional infiltration with spermatic cord block (inguinal/scrotal procedures) with weight-based liposomal bupivacaine plus bupivacaine hydrochloride or bupivacaine hydrochloride alone. The primary outcome was opioid-free rate at 48 hours. Secondary outcomes included parents' postoperative pain measure scores, numerical pain scale scores, and weight-based opioid utilization at 48 hours and 10 to 14 days. RESULTS: We randomized 104 participants, with > 98% (102/104) with complete follow-up data at 48 hours and 10 to 14 days. At interim analysis, there was no significant difference in opioid-free rate at 48 hours between arms (60% in the intervention vs 62% in the control group; estimated difference in proportion -1.9% [95% CI, -20%-16%]; P = .8). We observed no increased odds of patients being opioid-free at 48 hours with the intervention compared to the control group (OR 0.96 [95% CI 0.41-2.3]; P = .9). The trial met the predetermined futility threshold for early stopping. There was no difference in parents' postoperative pain measure scores, numerical pain scale scores, or opioid utilization at 48 hours or 10 to 14 days. No difference in adverse events was observed. CONCLUSIONS: The addition of liposomal bupivacaine to bupivacaine hydrochloride did not significantly improve opioid-sparing effect or postoperative pain compared with bupivacaine hydrochloride alone among children ≥ 6 years undergoing ambulatory urologic surgery.

RESUMO

PURPOSE: Transrectal prostate biopsy is a common ambulatory procedure that can result in pain and anxiety for some men. Low-dose, adjustable nitrous oxide is increasingly being used to improve experience of care for patients undergoing painful procedures. This study seeks to evaluate the efficacy and safety of low-dose (<45%) nitrous oxide, which has not been previously established for transrectal prostate biopsies. MATERIALS AND METHODS: A single-institution, prospective, double-blind, randomized, controlled trial was conducted on patients undergoing transrectal prostate biopsies. Patients were randomized to receive either self-adjusted nitrous oxide or oxygen, in addition to routine periprostatic bupivacaine block. Nitrous oxide at levels between 20% and 45% were adjusted to patients' desired effect. Patients completed a visual analog scale for anxiety, State Trait Anxiety Inventory, and a visual analog scale for pain immediately before and after biopsy. The blinded operating urologist evaluated ease of procedure. Periprocedural vitals and complications were assessed. Patients were allowed to drive home independently. RESULTS: A total of 133 patients received either nitrous oxide (66) or oxygen (67). There was no statistically significant difference in the primary anxiety end point of State Trait Anxiety Inventory or the visual analog scale for anxiety scores between the nitrous oxide and oxygen groups. However, patients in the nitrous oxide group reported significantly lower visual analog scale for pain scores compared to the oxygen group (P = .026). The operating urologists' rating of tolerance of the procedure was better in the nitrous oxide group (P = .03). There were no differences in biopsy performance time. Complications were similarly low between the 2 groups. CONCLUSIONS: Patient-adjusted nitrous oxide at levels of 20% to 45% is a safe adjunct during transrectal prostate biopsy. Although there was not an observed difference in the primary end point of anxiety, nitrous oxide was associated with lower patient-reported pain scores.

RESUMO

Resistant hypertension is defined as blood pressure above goal despite confirmed adherence to 3 first-line antihypertensive agents or when blood pressure is controlled with 4 or more medications at maximal or maximally tolerated doses. In addition to meeting these criteria, identifying patients with true resistant hypertension requires both accurate in-office blood pressure measurement as well as excluding white coat effects through out-of-office blood pressure measurements. Patients with resistant hypertension are at higher risk for adverse cardiovascular events and are more likely to have a potentially treatable secondary cause contributing to their hypertension. Effective treatment of resistant hypertension includes ongoing lifestyle modifications and collaboration with patients to detect and address barriers to optimal medication adherence. Pharmacologic treatment should prioritize optimizing first-line, once daily, longer acting medications followed by the stepwise addition of second-, third-, and fourth-line agents as tolerated. Physicians should systematically evaluate for and address any underlying secondary causes. A coordinated, multidisciplinary team approach including clinicians with experience in treating resistant hypertension is essential. New treatment options, including both pharmacologic and device-based therapies, have recently been approved, and more are in the pipeline; their optimal role in the management of resistant hypertension is an area of ongoing research.

RESUMO

Background: Low-sodium (LS) salt substitution is recognized for its potential to reduce blood pressure (BP), but most research relies on office BP measurement (OBPM). There is a lack of data on salt substitution's effect on target organs, such as the kidney as measured by the urine albumin-to-creatinine ratio (UACR), and its impact on inflammatory cytokines, particularly high-sensitivity C-reactive protein (hs-CRP). To evaluate the effect of LS salt substitution on ambulatory BP measurement (ABPM), kidney function, and inflammation in middle-aged and elderly hypertensive patients. Methods: In this 12-month prospective, multi-center, randomized, double-blind study, 352 hypertensive patients were randomly assigned to the normal salt (NS) group (n = 176) or the LS group (n = 176) at a 1:1 ratio. ABPM, fasting blood, and morning first spot urine samples were obtained at baseline and the endpoint. Results: Of the 352 patients, 322 completed all follow-up surveys, and 301 underwent ABPM. In the LS roup, significant reductions were observed in 24-hr systolic BP (-2.3 mmHg), 24-hr diastolic BP (-1.5 mmHg), daytime systolic BP (-2.6 mmHg), daytime diastolic BP (-1 mmHg), and nighttime systolic BP (-0.1 mmHg) compared to the NS group (all p < 0.05). However, the change in nighttime diastolic BP was not statistically significant (-0.3 vs. 1.1 mmHg, p = 0.063). Additionally, the LS group showed a more substantial decrease in UACR (-2.05 vs. -7.40 µg/mg, p = 0.004) and hs-CRP (-0.06 vs. -0.24 mg/L, p = 0.048) compared to NS. Conclusions: LS salt substitution significantly decreased ABPM, suggesting a notable impact on hypertension. Furthermore, it demonstrated a protective impact on kidney function, as evidenced by changes in UACR. Additionally, LS salt substitution appeared to reduce inflammation, indicated by the decrease in hs-CRP levels. Clinical Trial Registration: The study was registered in the Chinese clinical trial registry (registration number: ChiCTR1800019727).

RESUMO

Background: The biggest health problem in most developed countries of the world, including Kazakhstan, is high morbidity and death rates due to cardiovascular diseases (CVD), both in urban and rural areas. As is known during the outbreak of COVID-19, the inaccessibility of many medical services played a big role in the incidence of CVD, in particular in the northern regions of the Republic of Kazakhstan (KZ). The objective of our research was to analyze the prevalence of CVD in city and village regions of the northern regions of the Republic of Kazakhstan, considering the outbreak period with forecasting. Methods: A descriptive study with forecasting was conducted based on the "Health of the population of the Republic of Kazakhstan and the activities of healthcare organizations", secondary statistical reporting data (collected volume) of the KZ. Information from this database was collected for five districts, two cities and one city of regional significance in the northern region of the KZ. Results: According to our descriptive study, the incidence of CVD indicates a comparatively large prevalence of CVD among the municipal population of the northern regions of the KZ. The prevalence of CVD in urban areas of the North Kazakhstan region (NKR) was 1682.02 (2015) and 4784.08 (2020) per 100,000 population. Among rural NKR residents, it was (per 100,000 population) 170.84 (2015) and 341.98 (2020). According to the forecast, by 2025, the incidence of CVD will grow, both in urban (7382.91/100,000) and in rural areas (417.29/100,000). Conclusions: Given the situation during the pandemic, the incidence of CVD has had a sharp increase, both in the rural and in urban areas of the northern regions of the KZ. This may be due to the poor availability of medical facilities, and medical services, which may have prevented timely diagnosis, as well as the psychology of the situation and the load on cardiac activity in relation to the pandemic.

RESUMO

BACKGROUND: Disparities in life-saving interventions for low-income patients with cirrhosis necessitate innovative models of care. AIM: To implement a novel generalist-led FLuid ASPiration (FLASP) clinic to reduce emergency department (ED) care for refractory ascites. SETTING: A large safety net hospital in Los Angeles. PARTICIPANTS: MediCal patients with paracentesis in the ED from 6/1/2020 to 1/31/2021 or in FLASP clinic or the ED from 3/1/2021 to 4/30/2022. PROGRAM DESCRIPTION: According to RE-AIM, adoption obtained administrative endorsement and oriented ED staff. Reach engaged ED staff and eligible patients with timely access to FLASP. Implementation trained FLASP clinicians in safer, guideline-based paracentesis, facilitated timely access, and offered patient education and support. PROGRAM EVALUATION: After FLASP clinic opened, significantly fewer ED visits were made by patients discharged after paracentesis [rate ratio (RR) of 0.33 (95% CI 0.28, 0.40, p < 0.0001)] but not if subsequently hospitalized (RR = 0.88, 95% CI 0.70, 1.11). Among 2685 paracenteses in 225 FLASP patients, complications were infrequent: 39 (1.5%) spontaneous bacterial peritonitis, 265 (9.9%) acute kidney injury, and 2 (< 0.001%) hypotension. FLASP patients rated satisfaction highly on a Likert-type question. DISCUSSION: Patients with refractory ascites in large safety net hospitals may benefit from an outpatient procedure clinic instead of ED care.

RESUMO

BACKGROUND: Eating disorders (ED) are serious psychiatric disorders, taking a life every 52 minutes, with high relapse. There are currently no support or effective intervention therapeutics for individuals with an ED in their everyday life. The aim of this study is to build idiographic machine learning (ML) models to evaluate the performance of physiological recordings to detect individual ED behaviors in naturalistic settings. METHODS: From an ongoing study (Final N = 120), we piloted the ability for ML to detect an individual's ED behavioral episodes (e.g. purging) from physiological data in six individuals diagnosed with an ED, all of whom endorsed purging. Participants wore an ambulatory monitor for 30 days and tapped a button to denote ED behavioral episodes. We built idiographic (N = 1) logistic regression classifiers (LRC) ML trained models to identify onset of episodes (~600 windows) v. baseline (~571 windows) physiology (Heart Rate, Electrodermal Activity, and Temperature). RESULTS: Using physiological data, ML LRC accurately classified on average 91% of cases, with 92% specificity and 90% sensitivity. CONCLUSIONS: This evidence suggests the ability to build idiographic ML models that detect ED behaviors from physiological indices within everyday life with a high level of accuracy. The novel use of ML with wearable sensors to detect physiological patterns of ED behavior pre-onset can lead to just-in-time clinical interventions to disrupt problematic behaviors and promote ED recovery.

RESUMO

OBJECTIVE: Clinical decisions on managing epilepsy patients rely on patient accuracy regarding seizure reporting. Studies have noted disparities between patient-reported seizures and electroencephalographic (EEG) findings during video-EEG monitoring periods, chiefly highlighting underreporting of seizures, a well-recognized phenomenon. However, seizure overreporting is a significant problem discussed within the literature, although not in such a large cohort. Our aim is to quantify the over- and underreporting of seizures in a large cohort of ambulatory EEG patients. METHODS: We performed a retrospective data analysis on 3407 patients referred to a diagnostic service for ambulatory video-EEG between 2020 and 2022. Both patient-reported events and events discovered on review of the video-EEG were analyzed and classified as epileptic, psychogenic (typically clinical motor events, without accompanying EEG change), or noncorrelated events (NCEs; without perceivable clinical or EEG change). Events were analyzed by state of arousal and indication for referral. Subgroup analysis was performed in patients with focal and generalized epilepsies. RESULTS: A total of 21 024 events were recorded by 3407 patients. Fifty-eight percent of reported events were NCEs, whereas 27% of all events were epileptic. Sixty-four percent of epileptic seizures were not reported by the patient but discovered by the clinical service on review of the recording. NCEs were in the highest proportion in the awake and drowsy arousal states and were the most common event type for the majority of referral indications. Subgroup analysis found a significantly higher proportion of NCEs in the patients with focal epilepsy (23%) compared to generalized epilepsy (10%; p < .001, chi-squared proportion test). SIGNIFICANCE: Our results reaffirm the phenomenon of underreporting and highlight the prevalence of overreporting. Overreporting likely represents irrelevant symptoms or electrographic discharges not represented on scalp electrodes, identification of which has important clinical relevance. Future studies should analyze events by risk factors to elucidate relationships clinicians can use and investigate the etiology of NCEs.

RESUMO

BACKGROUND AND HYPOTHESIS: The aim of this study was to quantify hypertension control and evaluate concordance between all commonly available blood pressure modalities in kidney transplant recipients (KTR). METHODS: For this prospective cross-sectional study 89 stable KTR were recruited at the Charité Transplant Outpatient Clinic. For each study participant office (manual office blood pressure 'MOBP' and automated office blood pressure 'AOBP'), 7-day home (HBPM) and 24-hour ambulatory blood pressure measurement (24h-ABPM) were performed. RESULTS: 80 of the 89 patients recruited had sufficient blood pressure recordings. Mean blood pressure for MOBP, AOBP, HBPM and 24h-ABPM was 129/73, 126/71, 131/85 and 130/81 mmHg, respectively. Uncontrolled hypertension, as defined by 24h-ABPM (mean ≥ 130/80 mmHg), was present in 53 (66%) patients. MOBP, AOBP and HBPM classified 19 (24%), 22 (28%) and 41 (51%) patients respectively as 'uncontrolled hypertensive'. The Bland-Altman plot showed good agreement between systolic MOBP, AOBP, HBPM and Daytime-ABPM (mean bias ± SD: -1 ± 13 mmHg, -4 ± 13 mmHg, 1 ± 10 mmHg, respectively). Uncontrolled nighttime hypertension was present in 74 (93%) KTR, with 71 (89%) patients showing a non-physiological dipping pattern. Moderate positive correlation between Daytime-ABPM/HBPM and Nighttime-ABPM (Pearson Correlation Coefficients: 0.62-0.73), followed by MOBP/AOBP (Pearson Correlation Coefficients: 0.49-0.59) was noted. eGFR and proteinuria displayed weak correlation with 24h-, Daytime- and Nighttime-ABPM (absolute values of Pearson Correlation Coefficients: 0.04-0.41). No robust association with either 24h-, Daytime- or Nighttime-ABPM was observed for volume status exams. CONCLUSIONS: Masked hypertension is highly prevalent in KTR, especially due to high rates of uncontrolled nighttime hypertension. HBPM shows the narrowest limits of agreement with Daytime-ABPM. Daytime-ABPM and HBPM show the highest, albeit clinically insufficient, correlation with Nighttime-ABPM. Systematic integration of 24h-ABPM into clinical practice, as proposed by the '2023 ESH Guidelines for the Management of arterial hypertension', should not be withheld for the KTR population. Clinical trials evaluating treatment of hypertension in KTR are urgently needed.

RESUMO

BACKGROUND: The shared provider responsibility between married couples does not translate to equally shared division of childcare (CC) and household labor. While some marriages contain highly positive aspects, marriages may also simultaneously contain both positive and negative aspects. The negativity in these relationships can negate the positivity and could potentially lead to the detriment of mothers' health. PURPOSE: We examined mothers' ambulatory blood pressure (ABP) associated with their marital relationship quality and perceived equity with her spouse on CC and household tasks. METHODS: We investigate these associations using a mixed multilevel model analysis on a sample of 224 mothers in heterosexual marriages, all of whom had children under the age of 18 years currently living in the home. RESULTS: Mothers' perception of equity in the division of CC responsibilities contributed to lower ABP. Additionally, mothers in supportive marital relationships (low negativity and high positivity) had lower ABP than those in ambivalent relationships (both high negativity and positivity). There was a crossover interaction such that the effect of relationship quality on ABP was moderated by the perception of equity in the division of CC. For mothers who report doing all the CC, they had lower ABP if they had a supportive marital relationship compared with mothers in ambivalent relationships. Whereas mothers who report more equity in CC and have a supportive relationship have higher ABP compared with mothers in ambivalent relationships. CONCLUSIONS: This study has implications related to dynamics within marital relationships. These results demonstrate important relational influences on mothers' ABP.


Married mothers disproportionately shoulder the responsibilities of childcare (CC) and household labor. This inequity of the division of family responsibilities can negatively affect the relationship between husbands and wives with marital satisfaction being higher when the load is more equally shared between partners. Additionally, marital satisfaction is associated with numerous health benefits including lower blood pressure. We examined mothers' ambulatory blood pressure (ABP) associated with their marital relationship quality and perceived equity with her spouse on CC and household tasks on a sample of 224 mothers in heterosexual marriages. Mothers' perception of equity in the division of CC responsibilities contributed to lower ABP. Additionally, mothers in supportive marital relationships had lower ABP than those reporting less supportive relationships. There was an interaction between the perception of equity in the division of CC and the effect that relationship quality had on mothers' ABP. Mothers who reported doing all the CC had lower ABP if they had a supportive marital relationship compared with mothers in less supportive relationships. Whereas mothers who reported more equity in CC and had a supportive relationship had higher ABP compared with mothers in less supportive relationships.

RESUMO

BACKGROUND: Chronic ethnic discrimination may be associated with negative psychological consequences in ethnic minority groups. However, little is known about the impact of acute discriminatory events on people who experience chronic ethnic discrimination. PURPOSE: We examined the impact of chronic and acute ethnic discrimination on the daily lives of Turkish immigrants in Austria, a population often overlooked in discrimination research. METHODS: Ninety male Turkish immigrants living in Austria (60 experiencing chronic and 30 infrequent ethnic discrimination) reported discriminatory events in real time for 30 days. Additionally, subjective stress, reactivity to daily hassles, affect, and maladaptive coping were assessed daily. RESULTS: Participants experiencing chronic ethnic discrimination indicated higher daily values for stress, negative affect, reactivity to daily hassles, and anticipation and avoidance coping. Negative psychological states increased for all participants on days when discriminatory events occurred, but participants with chronic ethnic discrimination showed significantly stronger increases in maladaptive coping and reactivity to daily hassles, with the latter effect persisting until the next day. CONCLUSIONS: Our study is the first to demonstrate interaction effects of chronic and acute ethnic discrimination on psychological factors in daily life. The results may advance the understanding of the mechanisms that lead to health disparities in ethnic minority populations and may inform the development of targeted interventions.


This study investigated the impact of chronic and acute ethnic discrimination on the daily lives of Turkish immigrants in Austria, a population often overlooked in discrimination research. While it is established that experiences of ethnic discrimination are related to worse mental and physical health, the "how," that is, the underlying psychological mechanisms, remain incompletely understood. Ninety male Turkish immigrants took part in this study, with 60 experiencing ethnic discrimination on a regular basis. Over a 30-day period, we tracked their experiences of discrimination and their daily stress, emotional reactions, and coping strategies. We found that the participants with regular experiences of ethnic discrimination had higher stress levels and more negative emotions than the participants with fewer experiences of discrimination. In addition, they more strongly reacted to acute discriminatory events in their daily lives and had more problems coping with such events. They even were more stressed by daily hassles, which continued into the following day. These findings advance the understanding of the negative impact of ethnic discrimination on health disparities in ethnic minority populations and may inform the development of targeted interventions.
