Diverse learners: learning disabilities and quality of life following mind-body and health education interventions for adults with neurofibromatosis.

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.

Differences in intraoperative and surgical outcomes between normotensive pheochromocytomas and sympathetic paragangliomas (PPGLs) and hypertensive PPGLs: results from the PHEO-RISK STUDY.

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.

Prevalence, risk factors and evolution of diabetes mellitus after treatment in primary aldosteronism. Results from the SPAIN-ALDO registry.

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.

"Alone in the dark": A qualitative study of treatment experiences among young adults with a recent concussion and anxiety.

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.

"Hidden gains"? Measuring the impact of mindfulness-based interventions for people with mild traumatic brain injury: a scoping review.

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.

Distributed Global Debris Thickness Estimates Reveal Debris Significantly Impacts Glacier Mass Balance.

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 ∼0.15 ± 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.

Global-scale coherence modulation of radiation-belt electron loss from plasmaspheric hiss.

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.

Epidemiology of Non-Tuberculous Mycobacteria isolated from clinical specimens in Madrid, Spain, from 2013 to 2017.

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.

A Century of Stability of Avannarleq and Kujalleq Glaciers, West Greenland, Explained Using High-Resolution Airborne Gravity and Other Data.

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.

Vulnerability of Southeast Greenland Glaciers to Warm Atlantic Water From Operation IceBridge and Ocean Melting Greenland Data.

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.
