RESUMEN
Protracted droughts lasting years to decades constitute severe threats to human welfare across the Indian subcontinent. Such events are, however, rare during the instrumental period (ca. since 1871 CE). In contrast, the historic documentary evidence indicates the repeated occurrences of protracted droughts in the region during the preinstrumental period implying that either the instrumental observations underestimate the full spectrum of monsoon variability or the historic accounts overestimate the severity and duration of the past droughts. Here we present a temporally precise speleothem-based oxygen isotope reconstruction of the Indian summer monsoon precipitation variability from Mawmluh cave located in northeast India. Our data reveal that protracted droughts, embedded within multidecadal intervals of reduced monsoon rainfall, frequently occurred over the past millennium. These extreme events are in striking temporal synchrony with the historically documented droughts, famines, mass mortality events, and geopolitical changes in the Indian subcontinent. Our findings necessitate reconsideration of the region's current water resources, sustainability, and mitigation policies that discount the possibility of protracted droughts in the future.

BACKGROUND: Exercise and dietary nutrition are considered crucial in human immunodeficiency virus (HIV)/ acquired immunodeficiency syndrome (AIDS) treatment protocols and people living with HIV/AIDS (PLWHA) rehabilitation care. However, there is no well-studied research evaluating the effects of combined interventions on the fitness and immune systems of PLWHA. Therefore, this study aimed to analyze the effects of exercise and dietary intervention on physical fitness, quality of life and immune response in PLWHA. METHODS: This was an experimental study, with a sample of 25 male PLWHA divided into two groups: the intervention group (IG: 12 participants) and the control group (CG: 13 participants). All participants have not had any exercise habits and nutritional supplements in the past six months. The participants in the IG completed 45 min of exercise (60-80% HRmax) 4 times per week for 4 weeks. The exercise was in the form of brisk walking or running. They were also given a nutritional dietary supplement 3 times a day for 4 weeks. The 13 individuals in the CG continued their normal daily life (physical activity and diet). The following parameters were evaluated before and after the intervention: body composition, physical fitness, immune response, quality of life (QoL), stress, dietary behavior, dietary habits, exercise motivation, and physical self-efficacy. RESULTS: The significant changes were observed in burnout of stress variables and physical efficiency index (PEI) of physical fitness in the IG (p =.023). Moreover, in the saliva samples, sal-T levels significantly increased only after the intervention in the IG (p =.012). Additionally, regarding the analysis of the interaction (group × time), there was a significant improvement in the reaction speed (p =.001) and grip strength (left: p =.002, right: p =.030) and a significant difference in physical satisfaction in QoL (p =.001), stress burnout (p =.043), self-confidence in physical efficacy (p =.045), external display (p =.008), and fulfillment (p =.047) in exercise motivation. Moreover, the significant effect of the intervention on emotional eating in dietary behavior was shown in the comparison of the IG before and after intervention (p =.001) and in the comparison of the IG group with the CG after the experiment (p =.013). However, there was no significant effect of time or interaction between the condition and time on body composition. CONCLUSIONS: In conclusion, exercise training and diet therapy caused changes in physical fitness and Sal-T levels, which had positive effects on the health promotion of PLWHA.

Hematology-oncology (HO) fellows receive limited instruction in the process of establishing a diagnosis for hematologic neoplasms, and learning neoplastic hematology often occurs in limited encounters. In the current study, we developed a web-based interactive pathology tutorial in neoplastic hematologic disorders for HO fellows to work up simulated cases and establish the diagnosis. An online system ("Pathology Playground") was utilized to load case materials including microscopic images and ancillary studies. Twelve high-yield simulated cases of common leukemias and lymphoma were included. At the beginning of each case, trainees review the clinical history and slide images, and then, they are given the option to request additional pathology work-up. Based on the results, they can enter their diagnostic impression. If the diagnosis is correct, the user is shown a short educational presentation. If the diagnosis is not correct, the user gets notified by the message "Incorrect." The tutorial was integrated in the educational curriculum of our HO fellowship program, and bimonthly teaching sessions were held to review two cases each time. During the sessions, trainees request ancillary studies to complete the diagnostic work-up using the software and interpret the findings. As the case is being worked up by the trainee, the hematopathologists and HO fellowship program director discuss the findings, the appropriate work-up tools, and the implications on management. All of our six HO fellows attended the sessions, and a survey from the trainees showed high ease of use of the system and they viewed it as a very useful educational tool. A pre-test and post-test were administered for one of the sessions, and the result showed improvement in the average from 62 to 73%. Expanding the use of this online interactive tutorial and incorporating additional cases would enhance its value as a learning resource.

Food spoilage is an ongoing global issue that contributes to rising carbon dioxide emissions and increased demand for food processing. This work developed anti-bacterial coatings utilising inkjet printing of silver nano-inks onto food-grade polymer packaging, with the potential to enhance food safety and reduce food spoilage. Silver nano-inks were synthesised via laser ablation synthesis in solution (LaSiS) and ultrasound pyrolysis (USP). The silver nanoparticles (AgNPs) produced using LaSiS and USP were characterised using transmission electron microscopy (TEM), Fourier transform infrared (FTIR) spectroscopy, UV-Vis spectrophotometry and dynamic light scattering (DLS) analysis. The laser ablation technique, operated under recirculation mode, produced nanoparticles with a small size distribution with an average diameter ranging from 7-30 nm. Silver nano-ink was synthesised by blending isopropanol with nanoparticles dispersed in deionised water. The silver nano-inks were printed on plasma-cleaned cyclo-olefin polymer. Irrespective of the production methods, all silver nanoparticles exhibited strong antibacterial activity against E. coli with a zone of inhibition exceeding 6 mm. Furthermore, silver nano-inks printed cyclo-olefin polymer reduced the bacterial cell population from 1235 (±45) × 106 cell/mL to 960 (±110) × 106 cell/mL. The bactericidal performance of silver-coated polymer was comparable to that of the penicillin-coated polymer, wherein a reduction in bacterial population from 1235 (±45) × 106 cell/mL to 830 (±70) × 106 cell/mL was observed. Finally, the ecotoxicity of the silver nano-ink printed cyclo-olefin polymer was tested with daphniids, a species of water flea, to simulate the release of coated packaging into a freshwater environment.

Approximately 5% of people in the United States engage in some form of consensual non-monogamy (CNM; Archives of Sexual Behavior, 2018, 47, 1439). Therapists are becoming increasingly aware of the need to treat members of CNM relationships, including polyamorous relationships. To date, no research has been conducted and little has been written about applying existing couple therapy models normed on heterosexual, cisgender, monogamous relationships to CNM or polyamorous relationships. Emotionally focused therapy (EFT) is an empirically supported treatment for relationship distress that offers promise for working with polyamorous relationships due to the model's systemic and attachment theoretical foundations. We propose EFT is an ideal model for working with polyamorous relationships because of the focus on externalizing, interpersonal and intrapersonal emotional and experiential coherence, and the attachment bond. Building and sustaining multiple attachment relationships allows for the fulfilment of a diverse range of relational needs and wants as well as provides a secure base for individual and relational exploration. In this article, we first provide general information about polyamory and discuss the research on attachment theory and polyamory. We then provide a step-by-step conceptualization of how EFT therapists can expand the model to include extra-dyadic attachment relationships. In addition, we include specific ways in which the model would need to be adapted when working with polyamorous clients. We conclude with recommendations for EFT therapists working with polyamorous relationships.

For centuries, cold temperatures have been used by humans for therapeutic, health and sporting recovery purposes. This application of cold for therapeutic purposes is regularly referred to as cryotherapy. Cryotherapies including ice, cold-water and cold air have been popularised by an ability to remove heat, reduce core and tissue temperatures, and alter blood flow in humans. The resulting downstream effects upon human physiologies providing benefits that include a reduced perception of pain, or analgesia, and an improved sensation of well-being. Ultimately, such benefits have been translated into therapies that may assist in improving post-exercise recovery, with further investigations assessing the role that cryotherapies can play in attenuating the ensuing post-exercise inflammatory response. Whilst considerable progress has been made in our understanding of the mechanistic changes associated with adopting cryotherapies, research focus tends to look towards the future rather than to the past. It has been suggested that this might be due to the notion of progress being defined as change over time from lower to higher states of knowledge. However, a historical perspective, studying a subject in light of its earliest phase and subsequent evolution, could help sharpen one's vision of the present; helping to generate new research questions as well as look at old questions in new ways. Therefore, the aim of this brief historical perspective is to highlight the origins of the many arms of this popular recovery and treatment technique, whilst further assessing the changing face of cryotherapy. We conclude by discussing what lies ahead in the future for cold-application techniques.

The use of whole-body cryotherapy (WBC) as a recovery intervention is prevalent amongst elite soccer players. However, there is a distinct lack of data available around chronic WBC use and post-match recovery markers in elite soccer. The aim of this study was to investigate the impact of different levels of WBC exposure on subjective and objective measures of post-match recovery in elite soccer players during a chronic exposure period. Sixteen male senior professional outfield soccer players participated in this study over two seasons. K means cluster analysis was used to classify low (-114 ± 2°C for 133 ± 2 s), medium (-121 ± 1°C for 173 ± 2 s) and high (-133 ± 1°C for 181 ± 2 s) cryotherapy exposure indexes (CEI). Salivary markers (immunoglobulin A (IgA) and alpha amylase (AA)) and subjective wellness scores (perceived fatigue, sleep quality, general muscle soreness and stress) were collected post-match across both seasons. Training load (session-RPE) was collected and used as a covariate to control for the load amongst groups. No differences were seen in perceived measures of wellness and salivary AA. Significantly lower IgA concentrations were observed in the medium CEI group (255 ± 32 µgâml-1) compared to the low (328 ± 38 µgâml-1) and high (306 ± 32 µgâml-1) groups. Therefore, increasing the level of chronic WBC exposure appears to have no additional benefit on subjective recovery and alpha amylase response post-match. However, there appears to be an optimal chronic WBC dose with regards to IgA response.
RESUMEN
A number of oxidoreductases from the VAO/para-cresol methylhydroxylase flavoprotein family catalyze the oxidation of para-substituted phenols. One of the best-studied is vanillyl-alcohol oxidase (VAO) from the fungus Penicillium simplicissimum For oxidation of phenols by VAO to occur, they must first be bound in the active site of the enzyme in their phenolate anion form. The crystal structure of VAO reveals that two tyrosine residues, Tyr-108 and Tyr-503, are positioned to facilitate this deprotonation. To investigate their role in catalysis, we created three VAO variants, Y108F, Y503F, and Y108F/Y503F, and studied their biochemical properties. Steady-state kinetics indicated that the presence of at least one of the tyrosine residues is essential for efficient catalysis by VAO. Stopped-flow kinetics revealed that the reduction of VAO by chavicol or vanillyl alcohol occurs at two different rates: kobs1, which corresponds to its reaction with the deprotonated form of the substrate, and kobs2, which corresponds to its reaction with the protonated form of the substrate. In Y108F, Y503F, and Y108F/Y503F, the relative contribution of kobs2 to the reduction is larger than in wild-type VAO, suggesting deprotonation is impaired in these variants. Binding studies disclosed that the competitive inhibitor isoeugenol is predominantly in its deprotonated form when bound to wild-type VAO, but predominantly in its protonated form when bound to the variants. These results indicate that Tyr-108 and Tyr-503 are responsible for the activation of substrates in VAO, providing new insights into the catalytic mechanism of VAO and related enzymes that oxidize para-substituted phenols.

AIMS: Natural killer (NK) cell enteropathy is a recently described clinically indolent condition characterised by atypical NK cell infiltrates in the gastrointestinal mucosa that mimics malignant lymphoma. We report a case that highlights the indolent clinical behaviour by documenting absence of clinical progression over 10 years. METHODS AND RESULTS: We report the case of a 69-year old female who had clinically long-standing abdominal pain and recurrent mucosal ulcerations associated with atypical NK cell infiltrates. The clinical, morphologic and immunophenotypical findings in this case were diagnostic of NK cell enteropathy. Review of the patient's prior biopsies demonstrated that this persisted without clinical progression for 10 years, confirming the clinical indolent course. CONCLUSION: Recognition of NK cell enteropathy is important to avoid over-diagnosing this benign condition as an aggressive lymphoma.

Glucose restriction (GR) impairs muscle cell differentiation and evokes myotube atrophy. Resveratrol treatment in skeletal muscle cells improves inflammatory-induced reductions in skeletal muscle cell differentiation. We therefore hypothesised that resveratrol treatment would improve muscle cell differentiation and myotube hypertrophy in differentiating C2C12 myoblasts and mature myotubes during GR. Glucose restriction at 0.6 g/L (3.3 mM) blocked differentiation and myotube hypertrophy versus high-glucose (4.5 g/L or 25 mM) differentiation media (DM) conditions universally used for myoblast culture. Resveratrol (10 µM) treatment increased SIRT1 phosphorylation in DM conditions, yet did not improve differentiation when administered to differentiating myoblasts in GR conditions. Resveratrol did evoke increases in hypertrophy of mature myotubes under DM conditions with corresponding elevated Igf-I and Myhc7 gene expression, coding for the 'slow' type I MYHC protein isoform. Inhibition of SIRT1 via EX-527 administration (100 nM) also reduced myotube diameter and area in DM conditions and resulted in lower gene expression of Myhc 1, 2 and 4 coding for 'intermediate' and 'faster' IIx, IIa and IIb protein isoforms, respectively. Resveratrol treatment did not appear to modulate phosphorylation of energy-sensing protein AMPK or protein translation initiator P70S6K. Importantly, in mature myotubes, resveratrol treatment was able to ameliorate reduced myotube growth in GR conditions over an acute 24-h period, but not over 48-72 h. Overall, resveratrol evoked myotube hypertrophy in DM conditions while favouring 'slower' Myhc gene expression and acutely ameliorated impaired myotube growth observed during glucose restriction.

The self-assembled trimetallic species [L2 Cu3 ]6+ contains a cavity that acts as a host to many different anions. By using X-ray crystallography, ESI-MS, and UV/Vis spectroscopy we show that these anions are encapsulated both in the solid state and aqueous systems. Upon encapsulation, the anions Br- , I- , CO32- , SiF62- , IO63- , VO43- , WO42- , CrO42- , SO42- , AsO43- , and PO43- are all precipitated from aqueous solution and can be removed by filtration. Furthermore, the cavity can be tuned to be selective to either phosphate or sulfate anions by variation of the pH. Phosphate anions can be removed from water, even in the presence of other common anions, reducing the concentration from 1000 to <0.1â ppm and recovering approximately 99 % of the phosphate anions.
RESUMEN
PURPOSE: The incidental detection of small renal masses is increasing. However, not all require aggressive treatments as up to 20% are benign and the majority of malignant tumors harbor indolent features. Improved preoperative diagnostics are needed to differentiate tumors requiring aggressive treatment from those more suitable for surveillance. We evaluated and compared confocal laser endomicroscopy with standard histopathology in ex vivo human kidney tumors as proof of principle towards diagnostic optical biopsy. MATERIALS AND METHODS: Patients with a solitary small renal mass scheduled for partial or radical nephrectomy were enrolled in study. Two kidneys were infused with fluorescein via intraoperative intravenous injection and 18 tumors were bathed ex vivo in dilute fluorescein prior to confocal imaging. A 2.6 mm confocal laser endomicroscopy probe was used to image tumors and surrounding parenchyma from external and en face surfaces after specimen bisection. Confocal laser endomicroscopy images were compared to standard hematoxylin and eosin analysis of corresponding areas. RESULTS: Ex vivo confocal laser endomicroscopy imaging revealed normal renal structures that correlated well with histology findings. Tumor tissue was readily distinguishable from normal parenchyma, demonstrating features unique to benign and malignant tumor subtypes. Topical fluorescein administration provided more consistent confocal laser endomicroscopy imaging than the intravenous route. Additionally, en face tumor imaging was superior to external imaging. CONCLUSIONS: We report what is to our knowledge the first feasibility study using confocal laser endomicroscopy to evaluate small renal masses ex vivo and provide a preliminary atlas of images from various renal neoplasms with corresponding histology. These findings serve as an initial and promising step toward real-time diagnostic optical biopsy of small renal masses.

Current challenges exist to widespread clinical implementation of genomic medicine and pharmacogenetics. The University of Florida (UF) Health Personalized Medicine Program (PMP) is a pharmacist-led, multidisciplinary initiative created in 2011 within the UF Clinical Translational Science Institute. Initial efforts focused on pharmacogenetics, with long-term goals to include expansion to disease-risk prediction and disease stratification. Herein we describe the processes for development of the program, the challenges that were encountered and the clinical acceptance by clinicians of the genomic medicine implementation. The initial clinical implementation of the UF PMP began in June 2012 and targeted clopidogrel use and the CYP2C19 genotype in patients undergoing left heart catheterization and percutaneous-coronary intervention (PCI). After 1 year, 1,097 patients undergoing left heart catheterization were genotyped preemptively, and 291 of those underwent subsequent PCI. Genotype results were reported to the medical record for 100% of genotyped patients. Eighty patients who underwent PCI had an actionable genotype, with drug therapy changes implemented in 56 individuals. Average turnaround time from blood draw to genotype result entry in the medical record was 3.5 business days. Seven different third party payors, including Medicare, reimbursed for the test during the first month of billing, with an 85% reimbursement rate for outpatient claims that were submitted in the first month. These data highlight multiple levels of success in clinical implementation of genomic medicine.

PURPOSE: We identified structural abnormalities in the spermatic cord nerves that may explain how microsurgical denervation of the spermatic cord provides pain relief in patients with chronic orchialgia. MATERIALS AND METHODS: We retrospectively reviewed a prospective database to compare spermatic cord biopsy specimens from 56 men treated with a total of 57 procedures for microsurgical denervation of the spermatic cord for chronic orchialgia vs a control group of men without pain treated with cord surgery, including varicocelectomy in 4 and radical orchiectomy in 6. Tissue biopsies were obtained from mapped regions of the spermatic cord in all cases. Biopsies stained with hematoxylin and eosin were examined by an independent pathologist. Three human cadaveric spermatic cords were dissected to confirm localization of the nerve distribution identified on pathological mapping. RESULTS: We identified a median of 25 small diameter (less than 1 mm) nerve fibers in the spermatic cord. Of the 57 procedures for orchialgia 48 (84%) showed wallerian degeneration in 1 or more of these nerves but only 2 of 10 controls (20%) had such degeneration (p = 0.0008). In decreasing order of nerve density the 3 primary sites (trifecta nerve complex) of these changes were the cremasteric muscle fibers (19 nerves per patient), perivasal tissues and vasal sheath (9 nerves per patient), and posterior cord lipomatous/perivessel tissues (3 nerves per patient). Cord nerve distribution mapped by the biopsies was confirmed by cadaveric dissection. CONCLUSIONS: In men with chronic orchialgia there appears to be wallerian degeneration in reproducible patterns in the spermatic cord nerve fibers. Transection of these nerves may explain the effect of the denervation procedure.

CONTEXT.: Anatomic pathology slide unknown conferences are usually limited to a microscopic slide, slide images, or a virtual slide that is previewed prior to a conference. The answer is provided at a conference along with the ancillary studies, such as immunohistochemical or molecular studies, that enabled the diagnosis. In this rigid system the learner never gains experience with an appropriate workup for cases that will enable the definitive diagnosis. OBJECTIVE.: To develop an interactive system in which the user can work through a difficult case, ordering stains and other special studies, ideally leading to more involvement and retention. DESIGN.: An online system was developed using HTML, PHP Hypertext Preprocessor, and JavaScript for ordering and result display. When the user selects a study, an image or text result is displayed. Studies include immunohistochemistry, cytogenetics, flow cytometry, molecular, and radiology. The user then selects the diagnosis and, if correct, is shown some additional didactics. RESULTS.: Unknown conferences were held at 3 institutions using this novel teaching method that allowed residents to work up unknown cases. Conferences are available online (http://www.drdoubleb.com/unknowns/) and include general, soft tissue, and hematopathology cases. Evaluations were obtained that showed that residents enjoyed the system, considered it better than standard unknown sessions and lectures, and wanted more sessions. CONCLUSIONS.: This system was very highly received by the residents in all programs, who enjoyed getting immediate results and being able to work through interesting cases. More widespread use of this system could make for an effective learning tool.

Ulcerative colitis, characterized by its relapsing and remissive nature, negatively affects perception, body image, and overall quality of life. The associated financial burden underscores the need for alternative treatment approaches with fewer side effects, alongside pharmaceutical interventions. Montmorency tart cherries, rich in anthocyanins, have emerged as a potential natural anti-inflammatory agent for ulcerative colitis. This manuscript outlines the study protocol for a randomized placebo-controlled trial investigating the effects of Montmorency tart cherry in individuals with ulcerative colitis. The trial aims to recruit 40 participants with mild to moderate disease activity randomly assign them to either a Montmorency tart cherry or placebo group. The intervention will span 6 weeks, with baseline and 6-week assessments. The primary outcome measure is the Inflammatory Bowel Disease Quality of Life Questionnaire. Secondary outcomes include other health-related questionnaires and biological indices. Statistical analysis will adhere to an intention-to-treat approach using linear mixed effect models. Ethical approval has been obtained from the University of Hertfordshire (cLMS/SF/UH/05240), and the trial has been registered as a clinical trial (NCT05486507). The trial findings will be disseminated through a peer-reviewed publication in a scientific journal.
RESUMEN
The purpose of this study was to undertake a randomized control trial examining the effects of a 12-week home-based physical activity program on Saudi Arabian adults with type 2 diabetes. Sixty-four patients with type 2 diabetes mellitus were recruited from the Jazan Diabetes and Endocrinology Center, located in the Jazan region of southwestern Saudi Arabia. Patients were randomly assigned to either control, i.e., usual care (males = 46.9% and females = 53.1%, age = 45.88 ± 8.51 years, mass = 76.30 ± 15.16 kg, stature = 160.59 ± 8.94 cm, body mass index (BMI) = 29.73 ± 6.24 kg/m2, years since diagnosis = 8.12 ± 6.22 years) or a home-based physical activity (males = 50% and females = 50%, age = 42.07 ± 9.72 years, mass = 74.58 ± 13.67 kg, stature = 158.94 ± 9.38 cm, BMI = 29.44 ± 4.38 kg/m2, years since diagnosis = 12.17 ± 8.38 years) trial arms. The home-based physical activity group was required to undertake aerobic training by increasing their habitual step count by 2000 steps per day and performing resistance training 3 times per week for 12 weeks. The primary outcome was hemoglobin A1c (HbA1c), and secondary measures of anthropometrics, blood biomarkers, physical fitness, and patient-reported quality of life outcomes pertinent to type 2 diabetes were measured at timepoints, i.e., baseline, 12 weeks, and 24 weeks (follow-up). Intention-to-treat analyses revealed no significant alterations in the primary outcome (control: baseline = 8.71%, 12-weeks = 8.35%, and follow-up = 8.72%; home-based physical activity: baseline = 8.32%, 12-weeks = 8.06%, and follow-up = 8.39%) between trial arms. However, improvements in psychological wellbeing at follow-up measured using the Patient Health Questionnaire-9 were significantly greater in the home-based physical activity group (baseline = 6.84, 12-weeks = 5.96, and follow-up = 5.00) compared to the control (baseline = 6.81, 12-weeks = 5.73, and follow-up = 8.53). No other statistically significant observations were observed. Home-based physical activity is not effective in mediating improvements in HbA1c levels or secondary hematological, blood pressure, anthropometric, or fitness indices. However, given the link between psychological wellbeing and the etiology/progression of disease activity in type 2 diabetes, home-based physical activity may be effective for tertiary disease management. Future trials should examine the efficacy of relative exercise intensities greater than those in the current study.
RESUMEN
A 16-year-old man with splenomegaly presented with ascites and bilateral leg eschars. Although he had intermittently elevated absolute monocyte counts, a diagnosis of juvenile myelomonocytic leukemia (JMML) was discounted because of his age and lack of persistent leukocytosis. Detailed examination demonstrated features consistent with Noonan syndrome (NS), including typical facies, growth retardation, a cardiac defect, and a history of a coagulopathy. He underwent a splenectomy where the surgeons encountered a rind of tissue composed of monocytes encasing the abdominal organs. After splenectomy, his leukocytes rose to over 100×10(9)/L with a monocytosis, suggesting JMML. On the basis of the clinical suspicion of NS, mutation analysis revealed a KRAS mutation, which is known to be common to both NS and JMML. Clinicians should have high index of suspicion for JMML in patients with Noonan features, regardless of a patient's age.

In general, arousal of emotions is often felt and expressed as a somatic experience in the body. In Emotionally Focused Couple Therapy (EFT), the deepening of emotional experiencing enables therapeutic change. This research explores the experiences of eight experienced EFT trainer therapists regarding their somatic experiences in their work with couples. Using interpretative phenomenological analysis of transcribed in-depth interviews, this research data yielded three core themes that captured therapists' experiences of using their own and couples' somatic experiences in therapy: (1) the importance and relevance of somatic experiences, (2) therapists' use of their own somatic experiences, and (3) working with clients' somatic experiences. The findings suggest that therapists do focus on their own and couples' somatic experiences in their work with couples, and that EFT therapists could benefit from a map to guide therapists how to focus on felt, somatic experiences as a way of maintaining an emphasis on emotional experience.

Interabled couples navigate various systems of care as they respond to the needs of the disabled partner. Interabled couples are defined as one disabled partner and one nondisabled partner. Emotionally focused therapy (EFT) has shown benefits in reducing relationship distress and increasing the experience of security within couples. The study used interpretative phenomenological analysis to address how EFT therapists make sense of their lived experience working with interabled couples in couple therapy. The purpose of the study was to examine the experiences of therapists' serving interabled couples. The study explored the experiences of 10 EFT therapists who served at least one interabled couple in couple therapy. Findings resulted in four superordinate themes, (a) ableism; (b) self-of-the-therapist; (c) reported relationship dynamics of interabled couples; and (d) the "fit" of EFT approach with interabled couples. The themes demonstrate a need to further identify disability-responsive practices within EFT in serving interabled couples.
