RESUMO
PURPOSE: Neurofibromatosis (NF) is associated with low quality-of-life (QoL). Learning disabilities are prevalent among those with NF, further worsening QoL and potentially impacting benefits from mind-body and educational interventions, yet research on this population is scarce. Here, we address this gap by comparing NF patients with and without learning disabilities on QoL at baseline and QoL-related gains following two interventions. METHODS: Secondary analysis of a fully-powered RCT of a mind-body program (Relaxation Response Resiliency Program for NF; 3RP-NF) versus an educational program (Health Enhancement Program for NF; HEP-NF) among 228 adults with NF. Participants reported QoL in four domains (Physical Health, Psychological, Social Relationships, and Environmental). We compare data at baseline, post-treatment, and 12-month follow-up, controlling for intervention type. RESULTS: At baseline, individuals with NF and learning disabilities had lower Psychological (T = -3.0, p = .001) and Environmental (T = -3.8, p < .001) QoL compared to those without learning disabilities. Both programs significantly improved all QoL domains (ps < .0001-0.002) from baseline to post-treatment, regardless of learning disability status. However, those with learning disabilities exceeded the minimal clinically important difference in only one domain (Psychological QoL) compared to three domains in individuals without learning disabilities. Moreover, those with learning disabilities failed to sustain statistically significant gains in Psychological QoL at 12-months, while those without learning disabilities sustained all gains. CONCLUSION: Adults with NF and learning disabilities have lower Psychological and Environmental QoL. While interventions show promise in improving QoL regardless of learning disabilities, additional measures may bolster clinical benefit and sustainability among those with learning disabilities.

PURPOSE: To compare the intraoperative and surgical outcomes of normotensive pheochromocytomas and sympathetic paragangliomas (PPGLs), hypertensive PPGLs and non-PPGL adrenal lesions. METHODS: This a retrospective multicenter cohort study of patients with PPGLs from 18 tertiary hospitals. A control group of histologically confirmed adrenocortical adenomas (non-PPGL group) was selected to compare intraoperative and surgical outcomes with of the normotensive PPGLs. RESULTS: Two hundred and ninety-six surgeries performed in 289 patients with PPGLs were included. Before surgery, 209 patients were classified as hypertensive PPGLs (70.6%) and 87 as normotensive PPGLs. A higher proportion of normotensive PPGLs than hypertensive PPGLs did not receive alpha presurgical blockade (P = 0.009). When we only considered those patients who received presurgical alpha blockers (200 hypertensive PPGLs and 76 normotensive PPGLs), hypertensive PPGLs had a threefold higher risk of intraoperative hypertensive crisis (OR 3.0 [95% 1.3-7.0]) and of hypotensive episodes (OR 2.9 [95% CI 1.2-6.7]) than normotensive PPGLs. When we compared normotensive PPGLs (n = 76) and non-PPGLs (n = 58), normotensive PPGLs had a fivefold higher risk of intraoperative complications (OR 5.3 [95% CI 1.9-14.9]) and a six times higher risk of postoperative complications (OR 6.1 [95% CI 1.7-21.6]) than non-PPGLs. CONCLUSION: Although the risk of intraoperative hypertensive and hypotensive episodes in normotensive PPGLs is significantly lower than in hypertensive PPGLs, normotensive PPGLs have a greater risk of intraoperative and postoperative complications than non-PPGL adrenal lesions. Therefore, it is recommended to follow the standard of care for presurgical and anesthetic management of PPGLs also in normotensive PPGLs.

PURPOSE: To evaluate the prevalence, risk factors and evolution of diabetes mellitus (DM) after targeted treatment in patients with primary aldosteronism (PA). METHODS: A retrospective multicenter study of PA patients in follow-up at 27 Spanish tertiary hospitals (SPAIN-ALDO Register). RESULTS: Overall, 646 patients with PA were included. At diagnosis, 21.2% (n = 137) had DM and 67% of them had HbA1c levels < 7%. In multivariate analysis, family history of DM (OR 4.00 [1.68-9.53]), the coexistence of dyslipidemia (OR 3.57 [1.51-8.43]) and advanced age (OR 1.04 per year of increase [1.00-1.09]) were identified as independent predictive factors of DM. Diabetic patients were on beta blockers (46.7% (n = 64) vs. 27.5% (n = 140), P < 0.001) and diuretics (51.1% (n = 70) vs. 33.2% (n = 169), p < 0.001) more frequently than non-diabetics. After a median follow-up of 22 months [IQR 7.5-63.0], 6.9% of patients developed DM, with no difference between those undergoing adrenalectomy and those treated medically (HR 1.07 [0.49-2.36], p = 0.866). There was also no significant difference in the evolution of glycemic control between DM patients who underwent surgery and those medically treated (p > 0.05). CONCLUSION: DM affects about one quarter of patients with PA and the risk factors for its development are common to those of the general population. Medical and surgical treatment provides similar benefit in glycemic control in patients with PA and DM.

PURPOSE: Young adults with anxiety are vulnerable to developing persistent symptoms following concussions. In order to develop psychosocial interventions to prevent persistent post-concussion symptoms, we need to understand patients' 1) experiences with treatments offered by health care providers; 2) experiences with attempted concussion management strategies; and 3) needs after their injury. METHODS: We conducted in-depth interviews with 17 young adults with recent (≤ 10 weeks) concussions who have at least mild anxiety (Generalized Anxiety Disorder Assessment-7 ≥ 5). We used a hybrid deductive-inductive approach to thematic analysis. RESULTS: Findings provide insight into recommended treatments (e.g., active/avoidant strategies, accommodations, referrals), attempted strategies (e.g., lifestyle changes, pacing, relationships, acceptance-based coping skills), and patient needs (e.g., education, accommodations, referrals for cognitive and emotional skills). Participants frequently expressed that treatment recommendations were confusing and difficult to implement. They initiated non-prescribed strategies that helped promote recovery and expressed a desire for more interdisciplinary treatment and education on concussions. CONCLUSION: Patients' perceptions of health care provider recommendations after concussions did not fully meet patients' perceived needs. Young adults with concussions and anxiety would benefit from more education, guidance, and psychosocial and rehabilitation services. Addressing these gaps may help align treatments with patients' needs and therefore help optimize their recovery.
RESUMO
BACKGROUND: Mindfulness-based interventions can support recovery from mild traumatic brain injury (mTBI). Although measurement is a key determinant of outcomes, there is no comprehensive assessment of measurement approaches used to capture outcomes of these programs. Here, we review the domains targeted, measurement techniques used, and domains and techniques most affected by mindfulness-based interventions for mTBI. METHODS: We conducted a scoping review. After screening and full-text review, we included 29 articles and extracted data related to measurement domains, techniques, and results. RESULTS: We identified 8 outcome domains, each with multiple subdomains. The most common domains were cognitive symptoms and general health/quality of life. No quantitative studies directly assessed sleep, physical-function, or pain-catastrophizing. Self-report was the most common measurement technique, followed by performance-based methods. Coping, somatic symptoms, emotional symptoms, stress response, and domains of cognition (particularly attention) were the most frequently improved domains. Qualitative results described benefits across all domains and suggested novel areas of benefit. Biomarkers did not reflect significant change. CONCLUSIONS: Mindfulness-based interventions for mTBI impact a range of clinical domains and are best captured with a combination of measurement approaches. Using qualitative methods and expanding the breadth of outcomes may help capture underexplored effects of mindfulness-based interventions for mTBI.

Supraglacial debris affects glacier mass balance as a thin layer enhances surface melting, while a thick layer reduces it. While many glaciers are debris-covered, global glacier models do not account for debris because its thickness is unknown. We provide the first globally distributed debris thickness estimates using a novel approach combining sub-debris melt and surface temperature inversion methods. Results are evaluated against observations from 22 glaciers. We find the median global debris thickness is â¼0.15 ± 0.06 m. In all regions, the net effect of accounting for debris is a reduction in sub-debris melt, on average, by 37%, which can impact regional mass balance by up to 0.40 m water equivalent (w.e.) yr-1. We also find recent observations of similar thinning rates over debris-covered and clean ice glacier tongues is primarily due to differences in ice dynamics. Our results demonstrate the importance of accounting for debris in glacier modeling efforts.
RESUMO
Over 40 years ago it was suggested that electron loss in the region of the radiation belts that overlaps with the region of high plasma density called the plasmasphere, within four to five Earth radii, arises largely from interaction with an electromagnetic plasma wave called plasmaspheric hiss. This interaction strongly influences the evolution of the radiation belts during a geomagnetic storm, and over the course of many hours to days helps to return the radiation-belt structure to its 'quiet' pre-storm configuration. Observations have shown that the long-term electron-loss rate is consistent with this theory but the temporal and spatial dynamics of the loss process remain to be directly verified. Here we report simultaneous measurements of structured radiation-belt electron losses and the hiss phenomenon that causes the losses. Losses were observed in the form of bremsstrahlung X-rays generated by hiss-scattered electrons colliding with the Earth's atmosphere after removal from the radiation belts. Our results show that changes of up to an order of magnitude in the dynamics of electron loss arising from hiss occur on timescales as short as one to twenty minutes, in association with modulations in plasma density and magnetic field. Furthermore, these loss dynamics are coherent with hiss dynamics on spatial scales comparable to the size of the plasmasphere. This nearly global-scale coherence was not predicted and may affect the short-term evolution of the radiation belts during active times.
RESUMO
The epidemiology of non-tuberculous mycobacteria (NTM) in Spain is largely unknown because systematic reporting is not compulsory. The aim of our study was to describe the frequency and diversity of NTM species in our region and their distribution according to the source sample, gender, and age of the patients. We performed a multicenter study of all NTM isolated in 24 public hospitals in Madrid from 2013 to 2017. A total of 6.923 mycobacteria were isolated: 4535 (65.5%) NTM, and 2.388 (34.5%) Mycobacterium tuberculosis complex (MTB). Overall, 61 different NTM species were identified. The most frequently isolated species were Mycobacterium avium complex (47.7%), M. lentiflavum (12.2%), M. gordonae (9.2%), M. fortuitum (8.9%), and M. abscessus (3.9%). Whereas MTB cases were stable during the study period, the number of NTM isolates increased considerably from 930 isolates in 2013 to 1012 in 2017; a sharp increase occurred in the last year. The rise in NTM isolates was mostly due to M. lentiflavum, M. kansasii, and M. abscessus mainly isolated from respiratory specimens in patients older than 60. The increase in isolation rate of NTM in our region is consistent with the increasing rates reported worldwide in the last decades. The rise in NTM isolates was mainly attributed to M. lentiflavum but it also should be noted the increasing of species with high pathogenic potential such as M. kansasii and M. abscessus.

The evolution of Greenland glaciers in a warming climate depends on their depth below sea level, flow speed, surface melt, and ocean-induced undercutting at the calving front. We present an innovative mapping of bed topography in the frontal regions of Sermeq Avannarleq and Kujalleq, two major glaciers flowing into the ice-choked Torssukatak Fjord, central west Greenland. The mapping combines a mass conservation algorithm inland, multibeam echo sounding data in the fjord, and high-resolution airborne gravity data at the ice-ocean transition where other approaches have traditionally failed. We obtain a reliable, precision (±40 m) solution for bed topography across the ice-ocean boundary. The results reveal a 700 m deep fjord that abruptly ends on a 100-300 m deep sill along the calving fronts. The shallow sills explain the presence of stranded icebergs, the resilience of the glaciers to ocean-induced undercutting by warm Atlantic water, and their remarkable stability over the past century.
RESUMO
We employ National Aeronautics and Space Administration (NASA)'s Operation IceBridge high-resolution airborne gravity from 2016, NASA's Ocean Melting Greenland bathymetry from 2015, ice thickness from Operation IceBridge from 2010 to 2015, and BedMachine v3 to analyze 20 major southeast Greenland glaciers. The results reveal glacial fjords several hundreds of meters deeper than previously thought; the full extent of the marine-based portions of the glaciers; deep troughs enabling warm, salty Atlantic Water (AW) to reach the glacier fronts and melt them from below; and few shallow sills that limit the access of AW. The new oceanographic and topographic data help to fully resolve the complex pattern of historical ice front positions from the 1930s to 2017: glaciers exposed to AW and resting on retrograde beds have retreated rapidly, while glaciers perched on shallow sills or standing in colder waters or with major sills in the fjords have remained stable.
RESUMO
Greenland's bed topography is a primary control on ice flow, grounding line migration, calving dynamics, and subglacial drainage. Moreover, fjord bathymetry regulates the penetration of warm Atlantic water (AW) that rapidly melts and undercuts Greenland's marine-terminating glaciers. Here we present a new compilation of Greenland bed topography that assimilates seafloor bathymetry and ice thickness data through a mass conservation approach. A new 150 m horizontal resolution bed topography/bathymetric map of Greenland is constructed with seamless transitions at the ice/ocean interface, yielding major improvements over previous data sets, particularly in the marine-terminating sectors of northwest and southeast Greenland. Our map reveals that the total sea level potential of the Greenland ice sheet is 7.42 ± 0.05 m, which is 7 cm greater than previous estimates. Furthermore, it explains recent calving front response of numerous outlet glaciers and reveals new pathways by which AW can access glaciers with marine-based basins, thereby highlighting sectors of Greenland that are most vulnerable to future oceanic forcing.
RESUMO
Immune response stimulation to prevent infection progression may be an adjuvant to antimicrobial treatment. Lysophosphatidylcholine (LPC) is an immunomodulator involved in immune cell recruitment and activation. In this study, we aimed to evaluate the efficacy of LPC in combination with colistin, tigecycline, or imipenem in experimental murine models of peritoneal sepsis and pneumonia. We used Acinetobacter baumannii strain Ab9, which is susceptible to colistin, tigecycline, and imipenem, and multidrug-resistant strain Ab186, which is susceptible to colistin and resistant to tigecycline and imipenem. Pharmacokinetic and pharmacodynamic parameters for colistin, tigecycline, and imipenem and the 100% minimal lethal dose (MLD100) were determined for both strains. The therapeutic efficacies of LPC, colistin (60 mg/kg of body weight/day), tigecycline (10 mg/kg/day), and imipenem (180 mg/kg/day), alone or in combination, were assessed against Ab9 and Ab186 at the MLD100 in murine peritoneal sepsis and pneumonia models. The levels of pro- and anti-inflammatory cytokines, i.e., tumor necrosis factor alpha (TNF-α) and interleukin-10 (IL-10), were determined by enzyme-linked immunosorbent assay (ELISA) for the same experimental models after inoculating mice with the MLD of both strains. LPC in combination with colistin, tigecycline, or imipenem markedly enhanced the bacterial clearance of Ab9 and Ab186 from the spleen and lungs and reduced bacteremia and mouse mortality rates (P < 0.05) compared with those for colistin, tigecycline, and imipenem monotherapies. Moreover, at 4 h post-bacterial infection, Ab9 induced higher TNF-α and lower IL-10 levels than those with Ab186 (4 µg/ml versus 3 µg/ml [P < 0.05] and 2 µg/ml versus 3.4 µg/ml [P < 0.05], respectively). LPC treatment combined with colistin, tigecycline, or imipenem modestly reduced the severity of infection by A. baumannii strains with different resistance phenotypes compared to LPC monotherapy in both experimental models.

Host-viral genetic interaction has a key role in hepatitis C infection (HCV) and maybe in the viral selection. In a preliminary GWAS analysis, we identified BTN3A2 rs9104 to be associated with HCV genotype 1. Therefore, our aim was to determine the influence of BTN family on the selection of HCV genotype. We performed a fine-mapping analysis of BTN gene region in a cohort of chronic HCV infection (N=841), validating significant results in another independent chronic HCV infection cohort (N=637), according to selection of viral genotype. BTN3A2 rs9104, BTN3A2 rs733528, BTN2A1 rs6929846, BTN2A1 rs7763910 and BTN3A3 rs13220495 were associated with viral genotype selection. Interestingly, BTN3A2 rs9104 GG genotype was closely related to genotype 1 infection (80.7% (394/488) compared with genotype 3 infection (53.5% (23/43); P=0.0001) in patients harboring IL28B-CT/TT genotype, although this effect was not observed in IL28B-CC genotype. Similarly, BTN3A3 rs13220495 CC genotype was linked to genotype 3 infection (100% (32/32)) compared to genotype 1 (87.3% (137/157); P=0.028) in patients harboring IL28B-CC genotype, but did not in IL28B-CT/TT genotype. Genetic variants in the butyrophilin family genes may alter susceptibility to infection, selecting HCV genotype and influencing disease progression. BTN3A2 rs9104 was strongly associated with genotype 1 infection and the haplotype BTN3A3 rs13220495 CC+IL28B genotype CC was universal in patients with hepatitis C genotype 3a.

Past studies of radiation belt relativistic electrons have favored active storm time periods, while the effects of small geomagnetic storms (Dst > -50 nT) have not been statistically characterized. In this timely study, given the current weak solar cycle, we identify 342 small storms from 1989 through 2000 and quantify the corresponding change in relativistic electron flux at geosynchronous orbit. Surprisingly, small storms can be equally as effective as large storms at enhancing and depleting fluxes. Slight differences exist, as small storms are 10% less likely to result in flux enhancement and 10% more likely to result in flux depletion than large storms. Nevertheless, it is clear that neither acceleration nor loss mechanisms scale with storm drivers as would be expected. Small geomagnetic storms play a significant role in radiation belt relativistic electron dynamics and provide opportunities to gain new insights into the complex balance of acceleration and loss processes.
RESUMO
OBJECTIVES: To compare the efficacy and tolerability of the subcutaneous administration of N alpha methyl histamine versus oral propranolol in the treatment of migraine prophylaxis. BACKGROUND: N alpha methyl histamine has a selective affinity for H3 receptors and could constitute a new therapeutic drug in migraine prophylaxis. METHODS: Sixty patients with migraine were selected and enrolled in a 12-week double-blind controlled clinical trial to evaluate the efficacy of subcutaneous administration of N-alpha methyl histamine (1 to 3 ug twice a week ) n=30, compared to administration of 120 mg/day of oral propranolol n=30. the variables were: headache intensity, frequency of attacks, duration of migraine attacks and analgesic intake. RESULTS: fifty five patients completed the study. the data collected during the 4th week of treatment revealed that N alpha methyl histamine and propranolol caused a significantly (p<0.01) greater reduction between the basal values and final values of every variable studied. CONCLUSIONS: Both N alpha methyl histamine and propranolol are similarly effective in reducing or eliminating the headache in migraine prophylaxis. low doses of N-alpha methyl histamine injected subcutaneously may represent a novel and effective therapeutic alternative in migraine patients and may lay the clinical and pharmacological groundwork for the use of H3 receptor agonist in migraine prophylaxis.

The glaciers of North Greenland are hosting enough ice to raise sea level by 2.1 m, and have long considered to be stable. This part of Greenland is buttressed by the last remaining ice shelves of the ice sheet. Here, we show that since 1978, ice shelves in North Greenland have lost more than 35% of their total volume, three of them collapsing completely. For the floating ice shelves that remain we observe a widespread increase in ice shelf mass losses, that are dominated by enhanced basal melting rates. Between 2000 and 2020, there was a widespread increase in basal melt rates that closely follows a rise in the ocean temperature. These glaciers are showing a direct dynamical response to ice shelf changes with retreating grounding lines and increased ice discharge. These results suggest that, under future projections of ocean thermal forcing, basal melting rates will continue to rise or remain at high level, which may have dramatic consequences for the stability of Greenlandic glaciers.
RESUMO
College-aged individuals with anxiety are vulnerable to developing persistent concussion symptoms, yet evidence-based treatments for this population are limited. Understanding these individuals' perspectives is critical for developing effective interventions. We conducted qualitative interviews with 17 college-aged individuals (18-24 years old) with a recent (≤10 weeks) concussion and at least mild anxiety (≥5 on the GAD-7 questionnaire) to understand the life impact of their concussion. We identified 5 themes: (1) disruption to daily activities (e.g., reduced participation in hobbies and physical activity); (2) disruption to relationships (e.g., reduced social engagement, feeling dismissed by others, stigma, and interpersonal friction); (3) disruptions in school/work (e.g., challenges participating due to light sensitivity, cognitive or sleep disturbance, and related emotional distress); (4) changes in view of the self (e.g., feeling "unlike oneself", duller, or more irritable), and (5) finding "silver linings" after the injury (e.g., increased motivation). Concussions impact the lives of college-aged individuals with co-occurring anxiety in a broad range of domains, many of which remain largely neglected in standard concussion clinical assessment and treatment. Assessing and addressing these issues has the potential to limit the negative impact of concussion, promote recovery, and potentially help prevent persistent concussion symptoms in this at-risk population.

Importance: Neurofibromatoses (NF; NF1, NF2, and schwannomatosis) are hereditary tumor predisposition syndromes with a risk for poor quality of life (QOL) and no evidence-based treatments. Objective: To compare a mind-body skills training program, the Relaxation Response Resiliency Program for NF (3RP-NF), with a health education program (Health Enhancement Program for NF; HEP-NF) for improvement of quality of life among adults with NF. Design, Setting, and Participants: This single-blind, remote randomized clinical trial randomly assigned 228 English-speaking adults with NF from around the world on a 1:1 basis, stratified by NF type, between October 1, 2017, and January 31, 2021, with the last follow-up February 28, 2022. Interventions: Eight 90-minute group virtual sessions of 3RP-NF or HEP-NF. Main Outcomes and Measures: Outcomes were collected at baseline, after treatment, and at 6-month and 1-year follow-up. The primary outcomes were physical health and psychological domain scores of the World Health Organization Quality of Life Brief Version (WHOQOL-BREF). Secondary outcomes were the social relationships and environment domain scores of the WHOQOL-BREF. Scores are reported as transformed domain scores (range, 0-100, with higher scores indicating higher QOL). Analysis was performed on an intention-to-treat basis. Results: Of 371 participants who underwent screening, 228 were randomized (mean [SD] age, 42.7 [14.5] years; 170 women [75%]), and 217 attended 6 or more of 8 sessions and provided posttest data. Participants in both programs improved from baseline to after treatment in primary outcomes of physical health QOL score (3RP-NF, 5.1; 95% CI, 3.2-7.0; P < .001; HEP-NF, 6.4; 95% CI, 4.6-8.3; P < .001) and psychological QOL score (3RP-NF, 8.5; 95% CI, 6.4-10.7; P < .001; HEP-NF, 9.2; 95% CI, 7.1-11.2; P < .001). Participants in the 3RP-NF group showed sustained improvements after treatment to 12 months; posttreatment improvements for the HEP-NF group diminished (between-group difference for physical health QOL score, 4.9; 95% CI, 2.1-7.7; P = .001; effect size [ES] = 0.3; and psychological QOL score, 3.7; 95% CI, 0.2-7.6; P = .06; ES = 0.2). Results were similar for secondary outcomes of social relationships and environmental QOL. There were significant between-group differences from baseline to 12 months in favor of the 3RP-NF for physical health QOL score (3.6; 95% CI, 0.5-6.6; P = .02; ES = 0.2), social relationships QOL score (6.9; 95% CI, 1.2-12.7; P = .02; ES = 0.3), and environmental QOL score (3.5; 95% CI, 0.4-6.5; P = .02; ES = 0.2). Conclusions and Relevance: In this randomized clinical trial of 3RP-NF vs HEP-NF, benefits from 3RP-NF and HEP-NF were comparable after treatment, but at 12 months from baseline, 3RP-NF was superior to HEP-NF on all primary and secondary outcomes. Results support the implementation of 3RP-NF in routine care. Trial Registration: ClinicalTrials.gov Identifier: NCT03406208.

The growth of Haematococcus pluvialis in two alternative culture media NPK (10:10:10) and ME (macrophyte extract), under mixotrophic conditions using sugarcane molasses as a carbon source were evaluated for 28 days. The molasses was used in two different ways, in a native form (untreated) and a hydrolyzed (pretreated). Cell density of Haematococcus pluvialis in mixotrophic cultivation was higher in pretreated molasses. Growth rate was higher when pretreated molasses were employed in mixotrophic cultivation with NPK culture medium (k=0.5 7th growth day). Biomass, chlorophyll-a, conductivity and total inorganic nitrogen were not significantly different (p>0.05) during the experimental period for two mixotrophic cultivation and culture media. Protein contents of H. pluvialis biomass were higher in NPK culture medium with pretreated molasses (50% dry biomass). Annual biomass production was 520 kg-1 dry biomass with untreated molasses for two culture media, and 650 and 520 kg-1 dry biomass with pretreated molasses for NPK and ME culture media, respectively. The use of NPK and ME culture media in mixotrophic cultivation may be a new protocol for H. pluvialis cultivation due to the low cost and similar annual production.

INTRODUCTION: Patients admitted to the Neuroscience Intensive Care Unit (Neuro-ICU) with acute neurological illnesses (ANI; e.g., stroke, tumor, TBI) and their informal caregivers experience high rates of anxiety, depression, and posttraumatic stress. To address this need, we previously developed the Recovering Together (RT) dyadic intervention to help prevent chronic emotional distress in both patients and caregivers. Currently, we are conducting a fully-powered, single-blind randomized clinical trial (RCT) to evaluate the efficacy of RT versus an attention matched health education control. Here, we describe the protocol and current status of this RCT. METHODS: We aim to recruit 194 at risk patient-caregiver dyads from the Neuro-ICU at MGH. Eligible dyads include patients diagnosed with ANI, cognitively intact, at least one partner endorses emotional distress (on Hospital Anxiety and Depression Scale), English speaking, age 18 or older. Dyads are randomized to the intervention (RT-1) or control condition (RT-2) (both six sessions). RT-1 teaches resiliency (e.g., coping, mindfulness) and interpersonal skills. RT-2 provides education on health-related topics (e.g., stress, self-care, adhering to medical recommendations). Blinded research assistants collect measures at baseline, post-intervention, and three months follow-up. We will conduct mixed linear, mediation, and actor-partner interdependence models to examine changes in dyads' outcomes across time. RESULTS: We have recruited 41 dyads and aim to recruit 194 total. DISCUSSION: If successful, we plan to test RT in a large-scale, multisite hybrid effectiveness-implementation study in Neuro-ICUs across the country. Enhancing psychosocial supports for patients and families could improve health outcomes, healthcare efficiency, and the culture of these units.
