RESUMO

OBJECTIVE: This qualitative study explores patients' experiences of psychotherapy, focusing on elements perceived as helpful or unhelpful and suggestions for improvement in the context of public mental health care. METHODS: A total of 148 adults (Mean age = 32.24, SD = 9.92) who had been or are currently receiving psychological treatment from the National Health Service (NHS) responded to an online survey. The survey included open-ended questions regarding their experiences of psychotherapy, asking them to identify helpful or unhelpful aspects, and suggestions for improvement. Using thematic analysis, key themes were identified. RESULTS: The analysis highlighted the patient's preference for personalized treatment, the importance of therapeutic alliance, the demand for depth in therapy, and life skills and agency as therapeutic outcomes. Participants suggested improvements such as more tailored approaches and stronger therapist-patient relationships, supporting an adaptable, patient-centered model. CONCLUSION: The study highlights challenges in public mental health services where patients might feel their specific needs are not being recognized and met and underscores the importance of personalized treatment plans that satisfy and evolve with patient needs, suggesting that therapists must be attentive and responsive to individual desires to enhance the patient experience.

RESUMO

The plan formulation method (PFM) is an empirically validated procedure for identifying a patient's goals for therapy, what is hindering the patient from attaining those goals, and how the patient is likely to work in therapy. In this paper, we employ the PFM to analyze the initial psychotherapy sessions of Geena, a 30-year-old outpatient with borderline personality disorder and relational and substance abuse problems. Employing the PFM, we identify a family of pathogenic beliefs (e.g., that she is unlovable and unworthy; that her parents will be hurt if she has satisfying intimate relationships) that Geena sought to disprove in her therapy and explain how she worked with the therapist to do so. We illustrate how the PFM can help the therapist identify what information and what types of interventions will be helpful for a given patient.

RESUMO

Vingren, JL, Curtis, JH, Levitt, DE, Duplanty, AA, Lee, EC, McFarlin, BK, and Hill, DW. Adding resistance training to the standard of care for inpatient substance abuse treatment in men with human immunodeficiency virus improves skeletal muscle health without altering cytokine concentrations. J Strength Cond Res 32(1): 76-82, 2018-Substance abuse and human immunodeficiency virus (HIV) infection can independently lead to myopathy and related inflammatory alterations; importantly, these effects seem to be additive. Resistance training (RT) can improve muscle health in people living with HIV (PLWH), but the efficacy of this intervention has not been examined for PLWH recovering from substance abuse. The purpose of this study was to determine the effect of RT on muscle health markers (mass, strength, and power) and basal circulating biomarkers for men living with HIV undergoing substance abuse treatment. Men living with HIV undergoing 60-day inpatient substance abuse treatment completed either RT (3×/wk) or no exercise training (control) for 6 weeks. Muscle mass, strength, and power, and fasting circulating cytokines (interferon γ, tumor necrosis factor-α, interleukin (IL)-1ß, IL-2, IL-4, IL-6, and IL-10), vascular cellular adhesion molecule-1, and cortisol were measured before (PRE) and after (POST) the 6-week period. Both groups received the standard of care for HIV and substance abuse treatment determined by the inpatient facility. Muscle mass, strength, and power increased (p ≤ 0.05) from PRE to POST for RT but were unchanged for control. No differences were found for circulating biomarkers. Adding RT to the standard of care for substance abuse treatment improved aspects of muscle health (mass, strength, and power) in men living with HIV. These improvements are associated with a lower risk of a number of health conditions. Therefore, practitioners should consider implementing RT interventions as part of substance abuse treatment programs in this population to help manage long-term health.

RESUMO

Acute myeloid leukaemia (AML) patients with hyperleucocytosis have higher early mortality, lower complete remission (CR) and overall survival (OS). Whether different pre-induction leucoreduction strategies can improve outcome is unknown. A single centre retrospective cohort study was conducted on AML patients with a white blood cell count (WBC) >100 × 10(9) /l between 1987 and 1997, and on all AML patients between 1998 and 2006, to determine (a) the effect of four different leucoreductive strategies (leukapheresis, hydroxycarbamide, leukapheresis and hydroxycarbamide or no pre-induction leucoreduction) on early (day 28) mortality, CR, and OS; and (b) whether a high presenting WBC remains a negative predictor of OS in patients surviving induction (first 28 d). In the 1998-2006 cohort (n = 702), higher WBC was associated with higher early mortality and lower OS but its effects were greatly diminished in patients who survived the first 28 d (Hazard Ratio 1·094 vs. 1·002). A WBC of 34·1 × 10(9) /l had the highest sensitivity (75·6%) and specificity (67·4%) for early mortality. None of the four leucoreduction strategies differed significantly in early mortality, CR, or OS in patients with WBC>100 × 10(9) /l (n = 166). The number of leucostatic signs was a significant predictor of early mortality (P < 0·0001) and OS (P = 0·0007). The results suggest that AML patients with hyperleucocytosis should be induced, if eligible, without pre-induction leucoreduction.

RESUMO

The budding yeast Saccharomyces cerevisiae is a proven model organism for elucidating conserved eukaryotic biology, but to date its extracellular vesicle (EV) biology is understudied. Here, we show yeast transmit information through the extracellular medium that increases survival when confronted with heat stress and demonstrate the EV-enriched samples mediate this thermotolerance transfer. These samples contain vesicle-like particles that are exosome-sized and disrupting exosome biogenesis by targeting endosomal sorting complexes required for transport (ESCRT) machinery inhibits thermotolerance transfer. We find that Bro1, the yeast ortholog of the human exosome biomarker ALIX, is present in EV samples, and use Bro1 tagged with green fluorescent protein (GFP) to track EV release and uptake by endocytosis. Proteomics analysis reveals that heat shock protein 70 (HSP70) family proteins are enriched in EV samples that provide thermotolerance. We confirm the presence of the HSP70 ortholog stress-seventy subunit A2 (Ssa2) in EV samples and find that mutant yeast cells lacking SSA2 produce EVs but they fail to transfer thermotolerance. We conclude that Ssa2 within exosomes shared between yeast cells contributes to thermotolerance. Through this work, we advance Saccharomyces cerevisiae as an emerging model organism for elucidating molecular details of eukaryotic EV biology and establish a role for exosomes in heat stress and proteostasis that seems to be evolutionarily conserved.

RESUMO

Collapse of a lobe of a lung is an important indicator of a range of conditions, including malignancy. Clinical symptoms and signs may suggest a diagnosis of lobar collapse; however, it is often diagnosed, and always needs to be confirmed, with radiological examination. The radiological signs may be subtle, difficult to interpret and sometimes confusing to both clinicians and radiologists. Although multidetector CT (MDCT) is now widely in use for confirming and diagnosing lobar collapse, the plain chest radiograph is usually the first imaging modality performed and so recognition on the plain film remains of vital importance. The basics of chest radiograph interpretation are reviewed, concentrating on the concepts of radiographic density and the silhouette sign. MDCT images are used to demonstrate the general radiological signs of collapse, and the signs of collapse that are specific to the different lobes of the lung are reviewed.

RESUMO

15-Lipoxygenase (15-LOX) is one of the key enzymes responsible for the formation of oxidized low-density lipoprotein (ox-LDL), a major causal factor for atherosclerosis. Both enzymatic (15-LOX) and non-enzymatic (Cu(2+)) mechanisms have been proposed for the production of ox-LDL. We have recently reported that cannabidiol-2',6'-dimethyl ether (CBDD) is a selective and potent inhibitor of 15-LOX-catalyzed linoleic acid oxygenation (Takeda et al., Drug Metab. Dispos., 37, 1733-1737 (2009)). In the LDL, linoleic acid is present as cholesteryl linoleate, the major fatty acid esterified to cholesterol, and is susceptible to oxidative modification by 15-LOX or Cu(2+). In this investigation, we examined the efficacy of CBDD on i) 15-LOX-catalyzed oxygenation of cholesteryl linoleate, and ii) ox-LDL formation catalyzed by 15-LOX versus Cu(2+)-mediated non-enzymatic generation of this important mediator. The results obtained demonstrate that CBDD is a potent and selective inhibitor of ox-LDL formation generated by the 15-LOX pathway. These studies establish CBDD as both an important experimental tool for characterizing 15-LOX-mediated ox-LDL formation, and as a potentially useful therapeutic agent for treatment of atherosclerosis.

RESUMO

BACKGROUND: Drug abuse is a common problem in the United States. Drugs can be acquired in many ways, and can be knowingly or mistakenly misrepresented when sold. Propafenone is an uncommonly encountered class IC antidysrhythmic that is a look-alike for the opioid, oxycodone/acetaminophen 5/325. OBJECTIVE: We report a case of propafenone overdose presenting with generalized tonic-clonic seizure and a widened QRS complex, occurring after the patient had reported ingesting "Percocet®" (Endo Pharmaceuticals, Chadds Ford, PA). CASE REPORT: A 17-year-old boy presented to the emergency department (ED) after a witnessed seizure lasting 2 min. The patient reported having ingested 6 "Percocet®" tablets that he purchased from a classmate. He noted feeling weak and dizzy approximately 3 h after the ingestion, just before the seizure. On arrival in the ED, the patient was awake and alert with a QRS length of 168 ms. A sodium bicarbonate bolus and infusion shortened the QRS length to 90 ms. The patient was discharged the following day with no further complications. The pills were identified as propafenone hydrochloride (HCl) 225-mg tablets. The classmate surreptitiously sold the pills as "Percocet®" due to their similar "512" imprint. CONCLUSIONS: Pharmaceutical drugs are often sold on the street, and often misrepresented. Propafenone HCl 225-mg is an uncommonly encountered pharmaceutical, but is a look-alike for oxycodone/acetaminophen 5/325. An overdose due to propafenone ingestion may present with seizures and a widened QRS complex.

RESUMO

Household appliances represent substantial electricity load within the residential sector, particularly during the electricity system's period of peak evening load. While there is broad understanding of the factors that systematically impact on aggregate residential loads, much less is known about appliance loads. A research priority is understanding how socio-demographic, dwelling, and appliance factors are associated with the timing and scale of appliance loads. Using data from Ireland the analysis finds that the number of household occupants; number of appliances; and daytime occupancy of the home are closely associated with appliance loads but varies depending on the time of day. No association is found between appliance uses and building tenure, type or age; or socio-demographic variables such as income, age or education. The empirical findings have relevance for modelling residential electricity loads, and for design of measures to shift residential loads away from the evening peak period.

RESUMO

This paper studies the determinants of why low-income households in Ireland abandon energy efficiency retrofit applications using administrative data from a targeted energy efficiency grant. By applying for the scheme, the applicants overcome any financial barriers for undertaking retrofits and demonstrate their willingness to improve the energy efficiency of their dwellings. Hence this study contributes to the scarce literature on non-financial barriers preventing low-income households from undertaking energy efficiency retrofits. Contrary to previous findings, we find that the higher the number of retrofits to be implemented, the lower the probability of households abandoning their applications. We also find that planning to undertake retrofits such as ventilation, which can significantly improve the health and safety standards of the dwelling, is associated with a higher probability of abandonment. Both findings indicate the presence of key behavioural and informational barriers which prevent low-income households from fully comprehending the purpose or benefits of proposed energy efficient retrofits. Our findings also suggest that higher grant expenditure on dwellings with poor pre-works energy efficiency rating and on retrofits such as attic insulation and heating system upgrades may have the highest energy efficiency improvements per unit of expenditure. Within the constraints of limited budgets for retrofit grant supports, this research can inform the redesign of grant schemes to achieve the greatest aggregate improvements in residential building energy efficiency.

RESUMO

Nutritional ingredients with defined mechanisms of action can be useful in the recovery of the body from the physical demands of a habitual training plan. The purpose of this study was to determine the effect of dietary supplementation with optimized curcumin, pomegranate ellagitannins, and MSM (R + MSM) on immune-associated mRNA during early recovery (i.e., up to 8 h post-exercise) following all-out running efforts (5-km, 10-km, and 21.1-km). Subjects (N = 14) were randomized to either a supplement (R + MSM) or a control group using an open label design. The study was completed over a period of 31-day prior to a scheduled half-marathon race. Venous blood samples were collected into PAXgene tubes at baseline, subsequent samples were collected at 2, 4, and 8 h after each running effort. A 574-plex mRNA Immunology Array (NanoString) was measured for each sample and ROSALIND® Advanced Analysis Software was used to examined changes in 31 annotated immune response pathways and specific mRNA changes. The greatest change in immune pathways occurred at 2 h (GSS > 3) followed by 4 h (GSS 2-3) and 8 h (GSS 1-2). R + MSM was associated with an increase in innate immunity (CAMP, LTF, TIRAP, CR1, IL1R1, CXCR1, PDCDILG2, and GNLY) and a blunted/smaller increase in damage-associated molecular pattern (DAMP) signaling/inflammation (TLR4, TLR5, S100A8, S100A9, and IFP35). We also found changes in immune-associated mRNA that have not been previously linked to exercise recovery (SOCS1, SOCS2, MME, CECAM6, MX1, IL-1R2, KLRD1, KLRK1, and LAMP3). Collectively these results demonstrate that supplementation with a combination of optimized curcumin, pomegranate ellagitannins, and methylsulfonylmethane resulted in changes that may improve biological recovery from all-out running efforts.

RESUMO

The behavioral state of an animal is accompanied by ongoing brain activity that primes neuronal circuitry to sensory inputs. While it should come as no surprise that the pattern of cortical activation is tied to behavioral states, only now has this dependence been imaged. In this issue of Neuron, Ferezou, Bolea, and Petersen show that the level and spatial extent of activation of vibrissa sensory cortex critically depend on behavioral context and mode of stimulation, i.e., passive versus active contact.

RESUMO

Testing for drugs of abuse has become commonplace and is used for a variety of indications. Commonly employed testing methods include immunoassay and chromatography. Testing methods vary in their sensitivity, specificity, time, and cost. While urine remains the most common body fluid used for testing of drugs of abuse, over the last several decades the use of alternative matrices such as blood, sweat, oral fluids, and hair has increased dramatically. Each biological matrix offers advantages and disadvantages for drug testing, and the most appropriate matrix frequently depends on the indications for the drug test. Drugs of abuse that are most commonly tested include alcohol, amphetamines, cannabinoids, cocaine, opiates, and phencyclidine. Testing may involve detection of the parent compound or metabolites and sensitivity, specificity, and reliability of drug testing may vary depending on the drug being tested. Toxicologists have a responsibility to understand the strengths and limitations of testing techniques and matrices to be able to critically evaluate the results of a drug test.

RESUMO

Termination processes in psychotherapy vary widely across patients, therapists, and therapies. While general guidelines on termination can inform ethical and responsible termination practices, termination decisions and processes are likely optimized using a case-specific approach. Control-mastery theory (CMT) provides a framework for considering the unique ways individual patients work in psychotherapy and can be applied to help therapists understand and facilitate optimal terminations. The present article provides a brief overview of CMT and outlines perspectives regarding the decision-making and discussion of psychotherapy termination, the processing of termination, and the final session of therapy.

RESUMO

These data support the research article "Improving energy savings from a residential retrofit policy: a new model to inform better retrofit decisions" - (Mac Uidhir et al., 2019) [1]. This article presents 3 data sources which are utilised in conjunction with a detailed energy system model of the residential sector to explore policy pathways for residential retrofitting. Data is collected from the Central Statistics Office (CSO) and the Sustainable Energy Authority of Ireland (SEAI). The first SEAI dataset is compiled for Ireland in compliance with the EU Energy Performance of Buildings Directive (EPBD) [2]. Data is collected using the Dwelling Energy Assessment Procedure (DEAP) [3]. DEAP is used to produce energy performance certificates known as Building Energy Ratings (BER). A BER indicates a buildings energy performance across a 15-point energy efficiency scale, rated alphabetically from A1 to G, in units of kWh/m2 year. A BER is required for new buildings and the rent or sale of existing dwellings - therefore the database has consistently grown in size since its inception in 2006. The BER database contains 735,906 records of individual dwellings. The database includes detailed building fabric information across a range of different building types, year of construction, Main/Secondary space/water heating fuels, heating system efficiency, ventilation method and structure type (Insulated concrete form, Masonry, Timber or Steel Frame). The second SEAI dataset (PWBER) contains aggregated pre and post BER information for a sample of 112,007 dwellings retrofitted during the period 2010-2015; this database contains mean energy efficiency improvement (kWh/m2 year) for a range of retrofit combinations as they apply to nine distinct building archetypes. The third CSO dataset is compiled from census data, representing the frequency of building types by year of construction.

RESUMO

INTRODUCTION: Post-Traumatic Stress Disorder (PTSD) develops after experiencing events that evoke fear, helplessness, or horror. The Hyperarousablity Hypothesis suggests that those with PTSD may drink more to dampen physiological reactivity. We examined the direct and indirect relationships between childhood trauma (e.g., physical-neglect, emotional-abuse, physical-abuse, sexual-abuse) versus an emotionally-supportive-family on PTSD, impaired control over drinking (IC), alcohol-use, and alcohol-related-problems. IC reflects consuming more alcohol than one originally intended. METHODS: We fit a multiple-group SEM to data on 835 participants. Mediational analyses were conducted by using the (K = 20,000) bootstrap technique with confidence intervals. RESULTS: Physical-neglect was directly linked to more IC among both genders. Emotional abuse was also found to be directly linked to more PTSD among both genders. Furthermore, PTSD was directly linked to more impaired control over alcohol use (IC) among both genders. Mediational analyses showed that physical-neglect was indirectly linked to more alcohol-related-problems through increased IC. Having an emotionally supportive family was directly linked to fewer PTSD symptoms among women. For both genders, emotional abuse was indirectly linked to more alcohol-related-problems through more PTSD symptoms, impaired control over alcohol use difficulties, and in turn, more alcohol-use. Sexual abuse was indirectly linked to increased alcohol-related- problems through increased PTSD symptoms and more IC, and in turn, more alcohol-use among men. CONCLUSIONS: Recalled childhood trauma (sexual and emotional abuse) may contribute to PTSD symptoms and dysregulated drinking. In conclusion, our data suggest that reducing PTSD symptoms may assist individuals in regaining control over their drinking.

RESUMO

Rett syndrome (RTT) is a severe neurological disorder caused by mutations in the X-linked MECP2 gene, which encodes a methyl-CpG binding transcriptional repressor. Using the Mecp2-null mouse (an animal model for RTT) and differential display, we found that mice with neurological symptoms overexpress the nuclear gene for ubiquinol-cytochrome c reductase core protein 1 (Uqcrc1). Chromatin immunoprecipitation demonstrated that MeCP2 interacts with the Uqcrc1 promoter. Uqcrc1 encodes a subunit of mitochondrial respiratory complex III, and isolated mitochondria from the Mecp2-null brain showed elevated respiration rates associated with respiratory complex III and an overall reduction in coupling. A causal link between Uqcrc1 gene overexpression and enhanced complex III activity was established in neuroblastoma cells. Our findings raise the possibility that mitochondrial dysfunction contributes to pathology of the Mecp2-null mouse and may contribute to the long-known resemblance between Rett syndrome and certain mitochondrial disorders.

RESUMO

Individuals waiting for a renal transplant experience excessive cardiovascular mortality, which is not fully explained by the prevalence of ischemic heart disease in this population. Overt heart failure is known to increase the mortality of patients with ESRD, but the impact of lesser degrees of ventricular systolic dysfunction is unknown. For examination of the association between left ventricular ejection fraction(LVEF) and mortality of renal transplant candidates, the records of 2718 patients evaluated for transplantation at one institution were reviewed. During 6355 patient-years (median 27 mo) of follow-up, 681 deaths occurred. Patients with systolic dysfunction (LVEF
