Incremental sheet forming (ISF) is a manufacturing process most suitable for small-batch production of sheet metal parts. In ISF, a CNC-controlled tool moves over the sheet metal, following a specified contour to form a part of the desired geometry. This study focuses on one of the dominant process limitations associated with the ISF, i.e., the limited geometrical accuracy. In this regard, a case study is performed which shows that increased geometrical accuracy of the formed part can be achieved by a using stress-relief annealing before unclamping. To keep the tooling costs low, a modular die design consisting of a stiff metal frame and inserts made from inexpensive plastics (Sika®) were devised. After forming, the plastics inserts are removed. The metal frame supports the part during stress-relief annealing. Finite Element (FE) simulations of the manufacturing process are performed. Due to the residual stresses induced during the forming, the geometry of the formed part, from FE simulation and the actual manufacturing process, shows severe distortion upon unclamping the part. Stress relief annealing of the formed part under partial constraints exerted by the tool frame shows that a part with high geometrical accuracy can be obtained.

We conducted in-depth interviews with 11 Korean Disaster Relief Team (KDRT) members about stress related to disaster relief work and analyzed the interview data using the Consensual Qualitative Research (CQR) method in order to evaluate difficulties in disaster relief work and to develop solutions to these problems in cooperation with related organizations. Results showed that members typically experienced stress related to untrained team members, ineffective cooperation, and the shock and aftermath of aftershock experiences. Stress tended to stem from several factors: difficulties related to cooperation with new team members, the frightening disaster experience, and the aftermath of the disaster. Other stressors included conflict with the control tower, diverse problems at the disaster relief work site, and environmental factors. The most common reason that members participated in KDRT work despite all the stressors and difficulties was pride about the kind of work it involved. Many subjects in this study suffered from various stresses after the relief work, but they had no other choice than to attempt to forget about their experiences over time. It is recommended that the mental health of disaster relief workers will improve through the further development of effective treatment and surveillance programs in the future.

Stress fractures: diagnosis, treatment, and prevention.

PubMed

Patel, Deepak S; Roth, Matt; Kapil, Neha

2011-01-01

Stress fractures are common injuries in athletes and military recruits. These injuries occur more commonly in lower extremities than in upper extremities. Stress fractures should be considered in patients who present with tenderness or edema after a recent increase in activity or repeated activity with limited rest. The differential diagnosis varies based on location, but commonly includes tendinopathy, compartment syndrome, and nerve or artery entrapment syndrome. Medial tibial stress syndrome (shin splints) can be distinguished from tibial stress fractures by diffuse tenderness along the length of the posteromedial tibial shaft and a lack of edema. When stress fracture is suspected, plain radiography should be obtained initially and, if negative, may be repeated after two to three weeks for greater accuracy. If an urgent diagnosis is needed, triple-phase bone scintigraphy or magnetic resonance imaging should be considered. Both modalities have a similar sensitivity, but magnetic resonance imaging has greater specificity. Treatment of stress fractures consists of activity modification, including the use of nonweight-bearing crutches if needed for pain relief. Analgesics are appropriate to relieve pain, and pneumatic bracing can be used to facilitate healing. After the pain is resolved and the examination shows improvement, patients may gradually increase their level of activity. Surgical consultation may be appropriate for patients with stress fractures in high-risk locations, nonunion, or recurrent stress fractures. Prevention of stress fractures has been studied in military personnel, but more research is needed in other populations.

Pain is a common side effect of orthodontic treatment. It increases in proportion to the amount of force applied to the teeth, and the type of orthodontic appliance used can affect the intensity of the pain. Pain during orthodontic treatment has been shown to be the most common reason for people wanting to discontinue treatment, and has been ranked as the worst aspect of treatment. Although pharmacological methods of pain relief have been investigated, there remains some uncertainty among orthodontists about which painkillers are most suitable and whether pre-emptive analgesia is beneficial. We conducted this Cochrane Review to assess and summarize the international evidence relating to the effectiveness of analgesics for preventing this unwanted side effect associated with orthodontic treatment. The objectives of this review are to determine:- the effectiveness of drug interventions for pain relief during orthodontic treatment; and- whether there is a difference in the analgesic effect provided by different types, forms and doses of analgesia taken during orthodontic treatment. Cochrane Oral Health's Information Specialist searched the following databases: the Cochrane Oral Health Trials Register (to 19 June 2017), the Cochrane Central Register of Controlled Trials (CENTRAL;the Cochrane Library 2016, Issue 7), MEDLINE Ovid (1946 to 19 June 2017), Embase Ovid (1980 to 19 June 2017) and CINAHL EBSCO (Cumulative Index to Nursing and Allied Health Literature; 1937 to 19 June 2017). The US National Institutes of Health Ongoing Trials Register (ClinicalTrials.gov) and the World Health Organization International Clinical Trials Registry Platform were searched on the 19 June 2017 for ongoing studies. We placed no restrictions on language or date of publication when searching the electronic databases. We included randomized controlled trials (RCTs) relating to pain control during orthodontic treatment. Pain could be measured on a visual analogue scale (VAS), numerical

Two types of welded joints were prepared using low alloy carbon steel and austenitic stainless steel as base materials. In one variety, buttering material and weld metal were Inconel 82. In another type, buttering material and weld metal were Inconel 182. In case of Inconel 82, method of welding was GTAW. For Inconel 182, welding was done by SMAW technique. For one set of each joints after buttering, stress relief annealing was done at 923 K (650 °C) for 90 minutes before further joining with weld metal. Microstructural investigation and sub-size in situ tensile testing in scanning electron microscope were carried out for buttered-welded and buttered-stress relieved-welded specimens. Adjacent to fusion boundary, heat-affected zone of low alloy steel consisted of ferrite-pearlite phase combination. Immediately after fusion boundary in low alloy steel side, there was increase in matrix grain size. Same trend was observed in the region of austenitic stainless steel that was close to fusion boundary between weld metal-stainless steel. Close to interface between low alloy steel-buttering material, the region contained martensite, Type-I boundary and Type-II boundary. Peak hardness was obtained close to fusion boundary between low alloy steel and buttering material. In this respect, a minimum hardness was observed within buttering material. The peak hardness was shifted toward buttering material after stress relief annealing. During tensile testing no deformation occurred within low alloy steel and failure was completely through buttering material. Crack initiated near fusion boundary between low alloy steel-buttering material for welded specimens and the same shifted away from fusion boundary for stress relieved annealed specimens. This observation was at par with the characteristics of microhardness profile. In as welded condition, joints fabricated with Inconel 82 exhibited superior bond strength than the weld produced with Inconel 182. Stress relief annealing

Posttraumatic stress disorder in disaster relief workers following direct and indirect trauma exposure to Ground Zero.

2006-08-01

The present study compared rates of posttraumatic stress disorder (PTSD) in relief workers at the World Trade Center collapse from two sources: direct exposure to the disaster site and indirect exposure through survivor narratives. Standardized clinical interviews for PTSD were conducted with 109 relief workers 6-8 months after the September 11th terrorist attacks. Rates of acute PTSD from direct and indirect exposure to traumatic stressors were 6.4% and 4.6%, respectively. The findings suggest that indirect exposures can lead to PTSD even when Criterion A1 of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition-Text Revision (DSM-IV-TR; American Psychiatric Association, 2000, p. 463), i.e., "experienced by a family member or other close associate" is not met. Further research is necessary to define precisely the parameters of indirect traumatic exposure that may be linked to the development of PTSD.

Previous research suggests that patients' tendencies toward either reward or relief craving are distinct continuous factorial dimensions of craving for alcohol. According to these tendencies patients with alcohol use disorders (AUD) might also be allocated into distinct subgroups. In personalized treatment, patients of such different subgroups might respond differently to various psychotherapeutic and pharmacological interventions aimed at relapse prevention. To establish that the items of the subscale Temptation to Drink of the Alcohol Abstinence Self-Efficacy Scale (AASE) capture two continuous dimensions of reward and relief craving, and that they allow the identification of respective discrete class factors and subgroups of patients with AUD. Nonlinear confirmatory factor analysis (CFA) and latent class factor analysis (LCFA) were performed with data from 426 detoxified patients with AUD. The validity of continuous relief and reward dimensions, discrete class factors, and subtypes with different craving tendencies was established by including past drinking in positive and negative settings, gender, trait anxiety and perceived stress as covariates in the finally accepted CFA and LCFA measurement models. The AASE temptation items formed two continuous relief and reward craving factors. They also associated themselves to two binary class factors, which defined four craving subgroups. Two of them (21% and 29% of patients) were characterized by high levels of either reward or relief craving tendencies. A third subgroup (31%) rated both tendencies in an equal high measure, while a fourth (18%) reported almost no craving tendencies at all. Past drinking in negative and positive settings was significantly associated with relief or reward craving tendencies. Male patients reported reward drinking more frequently than female patients. Trait anxiety was positively related only to the relief craving tendency. Unexpectedly, patients' level of perceived stress was associated

Mechanical characterization and modeling of brazed tungsten and Cu-Cr-Zr alloy using stress relief interlayers

A rapidly solidified foil-type Ti-Zr based amorphous filler with a melting temperature of 850 °C was used to braze tungsten to Cu-Cr-Zr alloy for water cooled divertors and plasma facing components application. Brazed joints of dissimilar materials suffer from a mismatch in coefficients of thermal expansion. In order to release the residual stress caused by the mismatch, brazed joints of tungsten and Cu-Cr-Zr alloy using different interlayers were studied. The shear strength tests of brazed W/Cu joints show that the average strength of the joint with a W70Cu30 composite plate interlayer reached 119.8 MPa, and the average strength of the joint with oxygen free high conductivity copper (OFHC Cu)/Mo multi-interlayers reached 140.8 MPa, while the joint without interlayer was only 16.6 MPa. Finite element method (FEM) has been performed to investigate the stress distribution and effect of stress relief interlayers. FEM results show that the maximum von Mises stress occurs in the tungsten/filler interface and that the filler suffers the peak residual stresses and becomes the weakest zone. And the use of OFHC Cu/Mo multi-interlayers can reduce the residual stress significantly, which agrees with the mechanical experiment data.

Previous studies have suggested that the incidence of post-traumatic stress disorder in earthquake rescue workers is relatively high. Risk factors for this disorder include demographic characteristics, earthquake-related high-risk factors, risk factors in the rescue process, personality, social support and coping style. This study examined the current status of a unit of 1 040 rescue workers who participated in earthquake relief for the Wenchuan earthquake that occurred on May 12th, 2008. Post-traumatic stress disorder was diagnosed primarily using the Clinician-Administered Post-traumatic Stress Disorder Scale during structured interviews. Univariate and multivariate statistical analyses were used to examine major risk factors that contributed to the incidence of post-traumatic stress disorder. Results revealed that the incidence of this disorder in the rescue group was 5.96%. The impact factors in univariate analysis included death of family members, contact with corpses or witnessing of the deceased or seriously injured, near-death experience, severe injury or mental trauma in the rescue process and working at the epicenter of the earthquake. Correlation analysis suggested that post-traumatic stress disorder was positively correlated with psychotic and neurotic personalities, negative coping and low social support. Impact factors in multivariate logistic regression analysis included near-death experience, severe injury or mental trauma, working in the epicenter of the rescue, neurotic personality, negative coping and low social support, among which low social support had the largest odds ratio of 20.42. Findings showed that the occurrence of post-traumatic stress disorder was the result of the interaction of multiple factors. PMID:25206499

About two-thirds of the residual stress in cold-worked SAE 1050 steel tie rods was relieved by heating 30 minutes at 600 degrees Fahrenheit. Cold-worked austenitic stainless-steel tie rods could be heated at temperatures up to 1000 degrees Fahrenheit without lowering the important physical properties. The corrosion resistance, in laboratory corrosion test, of straight 18:8 and titanium-treated 18:8 materials appeared to be impaired after heating at temperatures above 800 degrees or 900 degrees fahrenheit. Columbium-treated and molybdenum-treated 18:8 steel exhibited improved stability over a wide range of temperatures. Tie rods of either material could be heated 30 minutes with safety at any temperature up to 1000 degrees Fahrenheit. At this temperature most of the residual stress would be relieved.

To build a sustainable workforce for long-term disaster relief and reconstruction, more effort must be made to promote local relief workers' mental health. We conducted 25 semistructured interviews with local relief officials 10 months after the 2008 earthquake in China to investigate the stress and coping experiences in their personal lives as survivors. We conducted thematic analysis of interview transcripts. Traumatic bereavement and grief, housing and financial difficulties, and work-family conflict were the three main sources of stress in the respondents' personal lives. The coping themes were finding meaning and purpose in life through relief work, colleagues' support and understanding, suppression or avoidance of grief, appreciation for life, hardiness, optimism, letting nature take its course, and making up for loss. We suggest that relief work has a double-edged-sword effect on workers' coping abilities. We discuss the implications of this effect for work-life balance measures and trauma and grief counseling services.

Pain relief for women with cervical intraepithelial neoplasia undergoing colposcopy treatment.

Pre-cancerous lesions of cervix (cervical intraepithelial neoplasia (CIN)) are usually treated with excisional or ablative procedures. In the UK, the National Health Service (NHS) cervical screening guidelines suggest that over 80% of treatments should be performed in an outpatient setting (colposcopy clinics). Furthermore, these guidelines suggest that analgesia should always be given prior to laser or excisional treatments. Currently various pain relief strategies are employed that may reduce pain during these procedures. To assess whether the administration of pain relief (analgesia) reduces pain during colposcopy treatment and in the postoperative period. We searched the Cochrane Central Register of Controlled Trials (CENTRAL 2016, Issue 2), MEDLINE (1950 to March week 3, 2016) and Embase (1980 to week 12, 2016) for studies of any design relating to analgesia for colposcopic management. We also searched registers of clinical trials, abstracts of scientific meetings, reference lists of included studies and contacted experts in the field. Randomised controlled trials (RCTs) that compared all types of pain relief before, during or after outpatient treatment to the cervix, in women with CIN undergoing loop excision, laser ablation, laser excision or cryosurgery in an outpatient colposcopy clinic setting. We independently assessed study eligibility, extracted data and assessed risk of bias. We entered data into Review Manager 5 and double checked it for accuracy. Where possible, we expressed results as mean pain score and standard error of the mean with 95% confidence intervals (CI) and synthesised data in a meta-analysis. We included 19 RCTs (1720 women) of varying methodological quality in the review. These trials compared a variety of interventions aimed at reducing pain in women who underwent treatment for CIN, including cervical injection with lignocaine alone, lignocaine with adrenaline, buffered lignocaine with adrenaline, prilocaine with felypressin, oral

When rock is cored at depth by drilling, anisotropic expansion occurs with the relief of anisotropic rock stresses, resulting in a sinusoidal variation of core diameter with a period of 180 deg. in the core roll angle. The circumferential variation of core diameter is given theoretically as a function of rock stresses. These new findings can lead various ideas to estimate the rock stress from circumferential variation of core diameter measured after the core retrieving. In the simplest case when a single core sample is only available, the difference between the maximum and minimum components of rock stress in a plane perpendicular to the drilled hole can be estimated from the maximum and minimum core diameters (see the detail in, Funato and Ito, IJRMMS, 2017). The advantages of this method include, (i) much easier measurement operation than those in other in-situ or in-lab estimation methods, and (ii) applicability in high stress environment where stress measurements need pressure for packers or pumping system for the hydro-fracturing methods higher than their tolerance levels. We have successfully tested the method at deep seismogenic zones in South African gold mines, and we are going to apply it to boreholes collared at 3 km depth and intersecting a M5.5 rupture plane several hundred meters below the mine workings in the ICDP project of "Drilling into Seismogenic zones of M2.0 - M5.5 earthquakes in deep South African gold mines" (DSeis) (e.g., http://www.icdp-online.org/projects/world/africa/orkney-s-africa/details/). If several core samples with different orientation are available, all of three principal components of 3D rock stress can be estimated. To realize this, we should have several boreholes drilled in different directions in a rock mass where the stress field is considered to be uniform. It is commonly carried out to dill boreholes in different directions from a mine gallery. Even in a deep borehole drilled vertically from the ground surface, the

2011-04-01

After the devastating 2008 earthquake in China, grass-roots government officials were the main local force in postquake relief and reconstruction. Like other survivors, many officials were severely bereaved. Their psychological well-being was at stake. We conducted 25 semistructured interviews to investigate sources of stress at work and their coping experiences. We coded interviews using the content analysis method. Misunderstandings and assaults from survivors, prolonged heavy workload, and grief and bereavement were major sources of stress at work. Finding meaning in the work, emotion regulation, and goal and time management were main coping strategies. The challenge and importance of the work, combined with support and recognition at work, fostered an empowering work environment. Few interviewees reported fatigue, whereas the majority displayed dedication to work, indicating a status of work engagement more than burnout among grass-roots officials. Implications of a meaning-oriented empowerment approach to stress management for disaster relief forces are drawn.

Relief Presentation on US National Park Service Maps

NASA Astrophysics Data System (ADS)

Patterson, Tom

2018-05-01

This paper examines the evolution of relief presentations on maps developed by Harpers Ferry Center, the media service center of the US National Park Service (NPS). Harpers Ferry Center produces the maps used by park visitors. I will discuss five park maps, each with a distinctive relief style and mode of production. They appear in rough chronological order of their development. Recent relief presentations are generally more detailed, colorful, and realistic than those from earlier years. Changing technology is largely responsible for the different relief styles found on park maps. Some relief treatments today were not possible, or imaginable, in 1977 when the NPS established the brochure program in its modern phase. Landscape heterogeneity is another factor behind the development of different relief styles. With over 400 park sites ranging from the glacial mountains of Alaska to the rolling piedmont of Virginia, a one-style-fits-all approach cannot adequately depict all landscapes. NPS maps serve some 300 million park visitors each year. Our ongoing effort to make understandable maps for this diverse audience has further spurred experiments in relief presentation.

The Effect of Heat Treatment on Residual Stress and Machining Distortions in Advanced Nickel Base Disk Alloys

NASA Technical Reports Server (NTRS)

Gayda, John

2001-01-01

This paper describes an extension of NASA's AST and IDPAT Programs which sought to predict the effect of stabilization heat treatments on residual stress and subsequent machining distortions in the advanced disk alloy, ME-209. Simple "pancake" forgings of ME-209 were produced and given four heat treats: 2075F(SUBSOLVUS)/OIL QUENCH/NO AGE; 2075F/OIL QUENCH/1400F@8HR;2075F/OIL QUENCH/1550F@3HR/l400F@8HR; and 2160F(SUPERSOLVUS)/OIL QUENCH/1550F@3HR/ 1400F@8HR. The forgings were then measured to obtain surface profiles in the heat treated condition. A simple machining plan consisting of face cuts from the top surface followed by measurements of the surface profile opposite the cut were made. This data provided warpage maps which were compared with analytical results. The analysis followed the IDPAT methodology and utilized a 2-D axisymmetric, viscoplastic FEA code. The analytical results accurately tracked the experimental data for each of the four heat treatments. The 1550F stabilization heat treatment was found to significantly reduce residual stresses and subsequent machining distortions for fine grain (subsolvus) ME209, while coarse grain (supersolvus) ME209 would require additional time or higher stabilization temperatures to attain the same degree of stress relief.

Modeling attitude towards drug treament: the role of internal motivation, external pressure, and dramatic relief.

PubMed

Conner, Bradley T; Longshore, Douglas; Anglin, M Douglas

2009-04-01

Motivation for change has historically been viewed as the crucial element affecting responsiveness to drug treatment. Various external pressures, such as legal coercion, may engender motivation in an individual previously resistant to change. Dramatic relief may be the change process that is most salient as individuals internalize such external pressures. Results of structural equation modeling on data from 465 drug users (58.9% male; 21.3% Black, 34.2% Hispanic/Latino, and 35.1% White) entering drug treatment indicated that internal motivation and external pressure significantly and positively predicted dramatic relief and that dramatic relief significantly predicted attitudes towards drug treatment: chi (2) = 142.20, df = 100, p < 0.01; Robust Comparative Fit Index = 0.97, Root Mean Squared Error of Approximation = 0.03. These results indicate that when external pressure and internal motivation are high, dramatic relief is also likely to be high. When dramatic relief is high, attitudes towards drug treatment are likely to be positive. The findings indicate that interventions to get individuals into drug treatment should include processes that promote Dramatic Relief. Implications for addictions health services are discussed.

To prospectively evaluate the effect of local wound infiltration with ropivacaine on postoperative pain relief and stress response reduction after open hepatectomy. A total of 56 patients undergoing open hepatectomy were randomly divided into two groups: a ropivacaine group (wound infiltration with ropivacaine solution) and a control group (infiltration with isotonic saline solution). A visual analog scale (VAS) at rest and on movement was used to measure postoperative pain for the first 48 h after surgery. Mean arterial pressure (MAP), heart rate (HR), time to bowel recovery, length of hospitalization after surgery, cumulative sufentanil consumption, and incidence of nausea and vomiting were compared between the two groups. Surgical stress hormones (epinephrine, norepinephrine, and cortisol) were detected using enzyme-linked immunosorbent assay, and the results were compared. VAS scores both at rest and on movement at 24 h and 48 h were similar between the two groups. Significantly lower VAS scores were detected at 0, 6, and 12 h in the ropivacaine group compared with the control group ( P < 0.05 for all). MAP was significantly lower at 6, 12, and 24 h ( P < 0.05 for all); HR was significantly lower at 0, 6, 12, and 24 h ( P < 0.05 for all); time to bowel recovery and length of hospitalization after surgery ( P < 0.05 for both) were significantly shortened; and cumulative sufentanil consumption was significantly lower at 6, 12, 24, and 36 h ( P < 0.05 for all) in the ropivacaine group than in the control group, although the incidence of nausea and vomiting showed no significant difference between the two groups. The levels of epinephrine, norepinephrine, and cortisol were significantly lower in the ropivacaine group than in the control group at 24 and 48 h ( P < 0.01 for all). Local wound infiltration with ropivacaine after open hepatectomy can improve postoperative pain relief, reduce surgical stress response, and accelerate postoperative recovery.

Cognitive behavioral therapy for insomnia as a preparatory treatment for exposure therapy for posttraumatic stress disorder.

Baddeley, Jenna L; Gros, Daniel F

2013-01-01

Insomnia is present in a majority of individuals with posttraumatic stress disorder (PTSD). However, when both disorders are present, disagreements exist about whether to provide exposure therapy for PTSD before insomnia treatment, or vice versa. The current case study describes the psychological treatment of a psychotherapy-naive veteran with comorbid insomnia and PTSD. The patient initially refused exposure therapy for PTSD; thus, cognitive-behavioral therapy for insomnia (CBTi) was a first-step treatment. Cognitive Behavior Therapy for Insomnia provided insomnia symptom relief psychoeducation and self-monitoring of PTSD symptoms prepared the patient to enter exposure therapy. After six CBTi sessions, the patient completed seven sessions of trauma-specific exposure therapy. At the conclusion of treatment and at 90-day follow up, the patient demonstrated significant reductions in insomnia and PTSD symptoms. Findings support the safe and effective use of CBTi in patients with comorbid insomnia and PTSD to improve sleep and facilitate entry into exposure therapy for PTSD.

Modeling Attitude towards Drug Treament: The Role of Internal Motivation, External Pressure, and Dramatic Relief

PubMed Central

Longshore, Douglas; Anglin, M. Douglas

2009-01-01

Motivation for change has historically been viewed as the crucial element affecting responsiveness to drug treatment. Various external pressures, such as legal coercion, may engender motivation in an individual previously resistant to change. Dramatic relief may be the change process that is most salient as individuals internalize such external pressures. Results of structural equation modeling on data from 465 drug users (58.9% male; 21.3% Black, 34.2% Hispanic/Latino, and 35.1% White) entering drug treatment indicated that internal motivation and external pressure significantly and positively predicted dramatic relief and that dramatic relief significantly predicted attitudes towards drug treatment: χ2=142.20, df=100, p<0.01; Robust Comparative Fit Index=0.97, Root Mean Squared Error of Approximation=0.03. These results indicate that when external pressure and internal motivation are high, dramatic relief is also likely to be high. When dramatic relief is high, attitudes towards drug treatment are likely to be positive. The findings indicate that interventions to get individuals into drug treatment should include processes that promote Dramatic Relief. Implications for addictions health services are discussed.

Vlemincx, Elke; Meulders, Michel; Abelson, James L

2017-04-01

Evidence suggests that sighs regulate stress and emotions, e.g. by facilitating relief. This study aimed to investigate sigh rates during relief. In addition, links between sighs, anxiety sensitivity and HPA-axis activity were explored. Healthy volunteers (N=29) were presented cues predicting the valence of subsequent stimuli. By sequencing cues that predicted pleasant or unpleasant stimuli with or without certainty, transitions to certain pleasantness (relief) or to certain unpleasantness (control) were created and compared to no transitions. Salivary cortisol, anxiety sensitivity and respiration were measured. Sigh frequency was significantly higher during relief than during control transitions and no transition states, and higher during control transitions than during no transition states. Sigh frequency increased with steeper cortisol declines for high anxiety sensitive persons. Results confirm a relationship between sighs and relief. In addition, results suggest that sigh frequency is importantly related to HPA-axis activity, particularly in high anxiety sensitive persons. Copyright © 2017 Elsevier B.V. All rights reserved.

Adams, David Z; Gruss, Richard; Abrahams, Alan S

2017-04-01

Product issues can cost companies millions in lawsuits and have devastating effects on a firm's sales, image and goodwill, especially in the era of social media. The ability for a system to detect the presence of safety and efficacy (S&E) concerns early on could not only protect consumers from injuries due to safety hazards, but could also mitigate financial damage to the manufacturer. Prior studies in the field of automated defect discovery have found industry-specific techniques appropriate to the automotive, consumer electronics, home appliance, and toy industries, but have not investigated pain relief medicines and medical devices. In this study, we focus specifically on automated discovery of S&E concerns in over-the-counter (OTC) joint and muscle pain relief remedies and devices. We select a dataset of over 32,000 records for three categories of Joint & Muscle Pain Relief treatments from Amazon's online product reviews, and train "smoke word" dictionaries which we use to score holdout reviews, for the presence of safety and efficacy issues. We also score using conventional sentiment analysis techniques. Compared to traditional sentiment analysis techniques, we found that smoke term dictionaries were better suited to detect product concerns from online consumer reviews, and significantly outperformed the sentiment analysis techniques in uncovering both efficacy and safety concerns, across all product subcategories. Our research can be applied to the healthcare and pharmaceutical industry in order to detect safety and efficacy concerns, reducing risks that consumers face using these products. These findings can be highly beneficial to improving quality assurance and management in joint and muscle pain relief. Copyright © 2017 Elsevier B.V. All rights reserved.

Does pain relief by CT-guided indirect cervical nerve root injection with local anesthetics and steroids predict pain relief after decompression surgery for cervical nerve root compression?

PubMed

Antoniadis, Alexander; Dietrich, Tobias J; Farshad, Mazda

2016-10-01

The relationship of pain relief from a recently presented CT-guided indirect cervical nerve root injection with local anesthetics and steroids to surgical decompression as a treatment for single-level cervical radiculopathy is not clear. This retrospective study aimed to compare the immediate and 6-week post-injection effects to the short- and long-term outcomes after surgical decompression, specifically in regard to pain relief. Patients (n = 39, age 47 ± 10 years) who had undergone CT-guided indirect injection with local anesthetics and steroids as an initial treatment for single cervical nerve root radiculopathy and who subsequently needed surgical decompression were included retrospectively. Pain levels (VAS scores) were monitored before, immediately after, and 6 weeks after injection (n = 34), as well as 6 weeks (n = 38) and a mean of 25 months (SD ± 12) after surgical decompression (n = 36). Correlation analysis was performed to find potential associations of pain relief after injection and after surgery to investigate the predictive value of post-injection pain relief. There was no correlation between immediate pain relief after injection (-32 ± 27 %) and 6 weeks later (-7 ± 19 %), (r = -0.023, p = 0.900). There was an association by tendency between immediate pain relief after injection and post-surgical pain relief at 6 weeks (-82 ± 27 %), (r = 0.28, p = 0.08). Pain relief at follow-up remained high at -70 ± 21 % and was correlated with the immediate pain amelioration effect of the injection (r = 0.37, p = 0.032). Five out of seven patients who reported no pain relief from injection had a pain relief from surgery in excess of 50 %. The amount of immediate radiculopathic pain relief after indirect cervical nerve root injection is associated with the amount of pain relief achieved at long-term follow-up after surgical decompression of single-level cervical radiculopathy

Research indicates that mirror therapy reduces phantom limb pain (PLP). Objectives were to determine when mirror therapy works in those who respond to treatment, the relevance of baseline PLP to when pain relief occurs, and what pain symptoms respond to mirror therapy. Data from two independent cohorts with unilateral lower limb amputation were analyzed for this study (n=33). Mirror therapy consisted of 15-min sessions in which amputees performed synchronous movements of the phantom and intact legs/feet. PLP was measured using a visual analogue scale and the Short-Form McGill Pain Questionnaire. The severity of PLP at the beginning of treatment predicted when pain relief occurred. Those with low baseline PLP experienced a reduction (p<0.05) in PLP by session 7 of treatment, those with medium baseline PLP experienced pain relief by session 14 of treatment, and those with high baseline PLP experienced pain relief by session 21 of treatment. Mirror therapy reduced throbbing, shooting, stabbing, sharp, cramping, aching, tender, splitting, tiring/exhausting, and punishing-cruel pain symptoms. The degree of PLP at baseline predicts when mirror therapy relieves pain. This article indicates that the degree of baseline PLP affects when mirror therapy relieves pain: relief occurs by session 7 in patients with low PLP but by session 21 in patients with high PLP. Clinicians should anticipate slower pain relief in patients who begin treatment with high levels of pain. ClinicalTrials.gov numbers:NCT00623818 and NCT00662415.

Should fertilization treatment start with reducing stress?

PubMed

Campagne, Daniel M

2006-07-01

In the past few decades, new and more efficient techniques to help solve fertility problems have become widely available throughout the developed world. These techniques include hormonal stimulation, ICSI, gamete intra-Fallopian transfer (GIFT) and IVF, and their cost is, on average, considerable. There is substantial initial evidence that the psychological disposition of the parents-to-be influences their fertility and thus the outcome of fertilization techniques. Many fertility treatments include consultation with a psychologist and do try to keep the stress produced by the treatment itself to a minimum, using concurrent therapy. However, the accumulating evidence points to the need to program medical fertility treatment, bearing in mind both chronic and acute stress levels, and to treat for their reduction before commencing the (actual) fertility treatment. There is ample evidence that lower stress levels mean better female and male natural fertility, though there is as yet no conclusive experimental evidence that lower stress levels result in better fertility treatment outcome. However, first reducing stress may diminish the number of treatment cycles needed before pregnancy is obtained, may prepare the couple for an initial failure of treatment or even make the more invasive techniques unnecessary. Primary psychological treatment for trait and state stress, being a less invasive method than IVF, ICSI or GIFT, is to be applied whenever indicated. Also, treatment and therapy to reduce stress, and in so doing enhance fertility, do not provoke the ethical and religious objections raised by infertility treatments.

Seeking Chronic Pain Relief: A Hermeneutic Exploration.

In the United States, chronic pain is experienced by over 39.4 million adults, many of whom are treated with opioid pain medications. This research presents an interpretation of the experience of seeking pain relief for a group of people taking opioid pain medications whose pain is not adequately controlled. A concurrent embedded mixed-methods design was used, including a Heideggerian hermeneutic qualitative approach that focuses on the participants' perceptions as a vehicle for understanding the phenomenon of seeking pain relief with descriptive quantitative data in a supporting role. Thirteen interviews and 15 surveys were analyzed, all of which met the following criteria: (1) self-reported chronic pain (persistent pain lasting a minimum of six months), (2) current use of prescription opioid medications, (3) pain not successfully controlled. The analysis revealed a paradox, which we describe as being lost/finding myself in the health care system. This paradox became the overarching pattern of experience that subsumed several dynamic, overlapping practices described in the patterns: (1) seeking relief as suffering; (2) being classified as an addict but not an addict; (3) living with pain as remembering; and (4) experiencing treatment modalities as fickle possibilities. Explication of and interpretive commentary on these patterns shift the focus from drug seeking to pain relief seeking behaviors in chronic pain sufferers. Such a shift could change the manner in which providers work with chronic pain sufferers to find appropriate treatment modalities. Copyright © 2018 American Society for Pain Management Nursing.

Fluid-structure interaction dynamic simulation of spring-loaded pressure relief valves under seismic wave

NASA Astrophysics Data System (ADS)

Lv, Dongwei; Zhang, Jian; Yu, Xinhai

2018-05-01

In this paper, a fluid-structure interaction dynamic simulation method of spring-loaded pressure relief valve was established. The dynamic performances of the fluid regions and the stress and strain of the structure regions were calculated at the same time by accurately setting up the contact pairs between the solid parts and the coupling surfaces between the fluid regions and the structure regions. A two way fluid-structure interaction dynamic simulation of a simplified pressure relief valve model was carried out. The influence of vertical sinusoidal seismic waves on the performance of the pressure relief valve was preliminarily investigated by loading sine waves. Under vertical seismic waves, the pressure relief valve will flutter, and the reseating pressure was affected by the amplitude and frequency of the seismic waves. This simulation method of the pressure relief valve under vertical seismic waves can provide effective means for investigating the seismic performances of the valves, and make up for the shortcomings of the experiment.

Social buffering: relief from stress and anxiety

PubMed Central

Kikusui, Takefumi; Winslow, James T; Mori, Yuji

2006-01-01

Communication is essential to members of a society not only for the expression of personal information, but also for the protection from environmental threats. Highly social mammals have a distinct characteristic: when conspecific animals are together, they show a better recovery from experiences of distress. This phenomenon, termed ‘social buffering’, has been found in rodents, birds, non-human primates and also in humans. This paper reviews classical findings on social buffering and focuses, in particular, on social buffering effects in relation to neuroendocrine stress responses. The social cues that transmit social buffering signals, the neural mechanisms of social buffering and a partner's efficacy with respect to social buffering are also detailed. Social contact appears to have a very positive influence on the psychological and the physiological aspects of social animals, including human beings. Research leading towards further understanding of the mechanisms of social buffering could provide alternative medical treatments based on the natural, individual characteristics of social animals, which could improve the quality of life.

Optimization of stress relief heat treatment of PHWR pressure tubes (Zr 2.5Nb alloy)

NASA Astrophysics Data System (ADS)

Choudhuri, Gargi; Srivastava, D.; Gurumurthy, K. R.; Shah, B. K.

2008-12-01

The micro-structure of cold worked Zr-2.5%Nb pressure tube material consists of elongated grains of α-zirconium enclosed by a thin film of β-zirconium phase. This β-Zr phase is unstable and on heating, progressively decomposes to α-Zr phase and β-phase enriched with Nb and ultimately form β Nb. Meta-stable ω-phase precipitates as an intermediate step during decomposition depending on the heat treatment schedule, β→α+β→α+ω+β→α+β→α+β Morphological changes occur in the β-zirconium phase during the decomposition. The continuous ligaments of β Zr phase turn into a discontinuous array of particles followed by globulization of the β-phase. The morphological changes impose a significant effect on the creep rate and on the delayed hydride cracking velocity due to reduction in the hydrogen diffusion coefficient in α Zr. If the continuity of β-phase is disrupted by heat treatment, the effective diffusion coefficient decreases with a concomitant reduction in DHC velocity. The pressure tubes for the Indian PHWRs are made by a process of hot extrusion followed by cold pilgering in two stages and an intermediate annealing. Autoclaving at 400 °C for 36 h ensures stress relieving of the finished tubes. In the present studies, autoclaving duration at 400 °C was varied from 24 h to 96 h at 12 h-steps and the micro-structural changes in the β-phase were observed by TEM. Dislocation density, hardness and the micro-structural features such as thickness of β-phase, inter-particle spacing and volume fraction of the phases were measured at each stage. Autoclaving for a longer duration was found to change the morphology of β-phase and increase the inter-particle spacing. Progressive changes in the aspect ratio of the β-phase and their size and distribution are documented and reported. These micro-structural modifications are expected to decrease DHC velocity during reactor operation.

Characterization of relief printing

2014-03-01

Relief printing technology developed by Océ allows the superposition of several layers of colorant on different types of media which creates a variation of the surface height defined by the input to the printer. Evaluating the reproduction accuracy of distinct surface characteristics is of great importance to the application of the relief printing system. Therefore, it is necessary to develop quality metrics to evaluate the relief process. In this paper, we focus on the third dimension of relief printing, i.e. height information. To achieve this goal, we define metrics and develop models that aim to evaluate relief prints in two aspects: overall fidelity and surface finish. To characterize the overall fidelity, three metrics are calculated: Modulation Transfer Function (MTF), difference and root-mean-squared error (RMSE) between the input height map and scanned height map, and print surface angle accuracy. For the surface finish property, we measure the surface roughness, generate surface normal maps and develop a light reflection model that serves as a simulation of the differences between ideal prints and real prints that may be perceived by human observers. Three sets of test targets are designed and printed by the Océ relief printer prototypes for the calculation of the above metrics: (i) twisted target, (ii) sinusoidal wave target, and (iii) ramp target. The results provide quantitative evaluations of the printing quality in the third dimension, and demonstrate that the height of relief prints is reproduced accurately with respect to the input design. The factors that affect the printing quality include: printing direction, frequency and amplitude of the input signal, shape of relief prints. Besides the above factors, there are two additional aspects that influence the viewing experience of relief prints: lighting condition and viewing angle.

Pressure Relief Devices

NASA Astrophysics Data System (ADS)

Manha, William D.

2010-09-01

Pressure relief devices are used in pressure systems and on pressure vessels to prevent catastrophic rupture or explosion from excessive pressure. Pressure systems and pressure vessels have manufacturers maximum rated operating pressures or maximum design pressures(MDP) for which there are relatively high safety factors and minimum risk of rupture or explosion. Pressure systems and pressure vessels that have a potential to exceed the MDP by being connected to another higher pressure source, a compressor, or heat to water(boiler) are required to have over-pressure protecting devices. Such devices can be relief valves and/or burst discs to safely relieve potentially excessive pressure and prevent unacceptable ruptures and explosions which result in fail-safe pressure systems and pressure vessels. Common aerospace relief valve and burst disc requirements and standards will be presented. This will include the NASA PSRP Interpretation Letter TA-88-074 Fault Tolerance of Systems Using Specially Certified Burst Disks that dictates burst disc requirements for payloads on Shuttle. Two recent undesirable manned space payloads pressure relief devices and practices will be discussed, as well as why these practices should not be continued. One example for discussion is the use of three burst discs that have been placed in series to comply with safety requirements of three controls to prevent a catastrophic hazard of the over-pressurization and rupture of pressure system and/or vessels. The cavities between the burst discs are evacuated and are the reference pressures for activating the two upstream burst discs. If the upstream burst disc leaks into the reference cavity, the reference pressure increases and it can increase the burst disc activating pressure and potentially result in the burst disc assembly being ineffective for over pressure protection. The three burst discs-in-series assembly was found acceptable because the burst discs are designed for minimum risk(DFMR) of

Suicide Prevention for Local Public and Volunteer Relief Workers in Disaster-Affected Areas.

Wang, Xiao Lu; Yip, Paul S F; Chan, Cecilia L W

2016-01-01

Local workforces play a critical role in disaster relief and reconstruction. However, the mental health of local relief workers might be affected by disasters, threatening the sustainability of local workforces. In this study, we tried to address this concern by investigating the well-being of local relief workers and its association with suicidal ideation. A retrospective study was conducted. Surveys were designed to collect data from a purposive sample of local disaster relief workers who survived a disaster. Binary logistic regression analysis was performed to test hypotheses. The study sample was from a population of local relief workers in the worst quake-hit regions in China in 2008. The respondents were local relief workers from a town in these regions. All of the 83 local relief workers were invited 11 months after the earthquake, and 70 joined the study, resulting in a response rate of 84.3%. The dependent variable was postdisaster suicidal ideation. The independent variables were bereavement, depression and posttraumatic stress, daily work hours, job burnout, work-family conflict, and work engagement. Approximately 21.4% of participants reported suicidal ideation after the earthquake in comparison with 7.1% before the earthquake. One potential risk factor was an interaction effect of job burnout and work-family conflict (odds ratio [OR] = 3.738; 95% confidence interval [CI], 1.086-12.868). Potential protective factors included daily work hours (OR = 0.317; 95% CI, 0.106-0.952) and work engagement (OR = 0.297; 95% CI, 0.091-0.969). Findings suggest that for local relief workers who are also disaster survivors, meaningful engagement such as participation in disaster relief could be salutary to their mental health, but overwork and interference with personal life could be harmful and increase the risk of suicidal ideation. Discretion is needed in managing local workforces, particularly with long work hours and work-family balance.

It is difficult to extend image-based relief generation to high-relief generation, as the images contain insufficient height information. To generate reliefs from three-dimensional (3D) models, it is necessary to extract the height fields from the model, but this can only generate bas-reliefs. To overcome this problem, an efficient method is proposed to generate bas-reliefs and high-reliefs directly from 3D meshes. To produce relief features that are visually appropriate, the 3D meshes are first scaled. 3D unsharp masking is used to enhance the visual features in the 3D mesh, and average smoothing and Laplacian smoothing are implemented to achieve better smoothing results. A nonlinear variable scaling scheme is then employed to generate the final bas-reliefs and high-reliefs. Using the proposed method, relief models can be generated from arbitrary viewing positions with different gestures and combinations of multiple 3D models. The generated relief models can be printed by 3D printers. The proposed method provides a means of generating both high-reliefs and bas-reliefs in an efficient and effective way under the appropriate scaling factors.

Posttraumatic stress disorder (PTSD) is typically accompanied by both acute and chronic alterations in the stress response. These alterations have mostly been described in individuals under baseline conditions, but studies have also used a challenge model to assess the role of the hypothalamic-pituitary-adrenal (HPA) axis in the stress response. The purpose of this article was to assess the effect of long-term treatment with the selective reuptake inhibitor (SSRI), paroxetine, on stress reactivity in patients with PTSD. We assessed diurnal salivary cortisol and urinary cortisol as well as cortisol, heart rate, and behavioral responses to a standardized cognitive stress challenge, in 13 female patients with chronic PTSD before and after 12 months of paroxetine treatment. Treatment resulted in a significant decrease in PTSD symptoms. Twenty-four-hour urinary cortisol was lower compared to base line after successful treatment. Treatment resulted in a decrease of salivary cortisol levels on all time points on a diurnal curve. Despite similar stress perception, cortisol response to the cognitive stress challenge resulted in a 26.5% relative decrease in stress-induced salivary cortisol with treatment. These results suggest that successful treatment with SSRI in chronic PTSD is associated with a trend for a decrease in baseline diurnal cortisol and with reduced cortisol reactivity to stress.

Intra-accumbal blockade of endocannabinoid CB1 receptors impairs learning but not retention of conditioned relief.

PubMed

Bergado Acosta, Jorge R; Schneider, Miriam; Fendt, Markus

Humans and animals are able to associate an environmental cue with the feeling of relief from an aversive event, a phenomenon called relief learning. Relief from an aversive event is rewarding and a relief-associated cue later induces an attenuation of the startle magnitude or approach behavior. Previous studies demonstrated that the nucleus accumbens is essential for relief learning. Here, we asked whether accumbal cannabinoid type 1 (CB1) receptors are involved in relief learning. In rats, we injected the CB1 receptor antagonist/inverse agonist SR141716A (rimonabant) directly into the nucleus accumbens at different time points during a relief learning experiment. SR141716A injections immediately before the conditioning inhibited relief learning. However, SR141716A injected immediately before the retention test was not effective when conditioning was without treatment. These findings indicate that accumbal CB1 receptors play an important role in the plasticity processes underlying relief learning. Copyright © 2017 Elsevier Inc. All rights reserved.

In order to determine some of the factors involved in the response of duodenal ulcers to placebo treatment, the following factors were studied prospectively during a double-blind, placebo-controlled trial: demographic data; duration of illness and effect of treatment; expectation of success or failure of the new drug; presence of psychiatric problems; and suggestibility. Healing (measured by endoscopy) occurred in 37 patients, 17 of whom were receiving placebo; relief of symptoms occurred in 35 patients, 16 of whom were receiving placebo. There was no significant difference between drug and placebo. Healing was significantly associated with relief of symptoms but with no other variable. Relief of symptoms was more common in male patients and in those from higher social classes, as well as in patients who expected a complete cure and those without evidence of psychiatric problems. the natural history of the disease may be different in these patients. Unexpectedly, suggestibility was not associated with healing or relief of symptoms in the patients receiving placebo. PMID:7016689

Fluid relief and check valve

DOEpatents

Blaedel, K.L.; Lord, S.C.; Murray, I.

A passive fluid pressure relief and check valve allows the relief pressure to be slaved to a reference pressure independently of the exhaust pressure. The pressure relief valve is embodied by a submerged vent line in a sealing fluid, the relief pressure being a function of the submerged depth. A check valve is embodied by a vertical column of fluid (the maximum back pressure being a function of the height of the column of fluid). The pressure is vented into an exhaust system which keeps the exhaust out of the area providing the reference pressure.

Disparity between General Symptom Relief and Remission Criteria in the Positive and Negative Syndrome Scale (PANSS): A Post-treatment Bifactor Item Response Theory Model.

Objective: Total scale scores derived by summing ratings from the 30-item PANSS are commonly used in clinical trial research to measure overall symptom severity, and percentage reductions in the total scores are sometimes used to document the efficacy of treatment. Acknowledging that some patients may have substantial changes in PANSS total scores but still be sufficiently symptomatic to warrant diagnosis, ratings on a subset of 8 items, referred to here as the "Remission set," are sometimes used to determine if patients' symptoms no longer satisfy diagnostic criteria. An unanswered question remains: is the goal of treatment better conceptualized as reduction in overall symptom severity, or reduction in symptoms below the threshold for diagnosis? We evaluated the psychometric properties of PANSS total scores, to assess whether having low symptom severity post-treatment is equivalent to attaining Remission. Design: We applied a bifactor item response theory (IRT) model to post-treatment PANSS ratings of 3,647 subjects diagnosed with schizophrenia assessed at the termination of 11 clinical trials. The bifactor model specified one general dimension to reflect overall symptom severity, and five domain-specific dimensions. We assessed how PANSS item discrimination and information parameters varied across the range of overall symptom severity (θ), with a special focus on low levels of symptoms (i.e., θ<-1), which we refer to as "Relief" from symptoms. A score of θ=-1 corresponds to an expected PANSS item score of 1.83, a rating between "Absent" and "Minimal" for a PANSS symptom. Results: The application of the bifactor IRT model revealed: (1) 88% of total score variation was attributable to variation in general symptom severity, and only 8% reflected secondary domain factors. This implies that a general factor may provide a good indicator of symptom severity, and that interpretation is not overly complicated by multidimensionality; (2) Post-treatment, 534 individuals

Substance abuse treatment programs are often characterized by high rates of premature treatment dropout, which increases the likelihood of relapse to drug use. Negative reinforcement models of addiction emphasize an individual's inability to tolerate stress as a key factor for understanding poor substance use treatment outcomes, and evidence indicates that dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis contributes to an individual's inability to respond adaptively to stress. The aim of the current study was to examine whether HPA axis response to stress is predictive of treatment retention among a sample of drug users in residential substance abuse treatment. Prospective study assessing treatment retention among 102 individuals enrolled in residential substance abuse treatment. Participants completed two computerized stress tasks, and HPA axis response to stress was measured via salivary cortisol at five time points from baseline (pre-stress) to 30 min post-stress exposure. The main outcome measures were treatment dropout (categorical) and total number of days in treatment (continuous). A significantly higher salivary cortisol response to stress was observed in treatment dropouts compared to treatment completers. Further, Cox proportional hazards survival analyses indicated that a higher peak cortisol response to stress was associated with a shorter number of days to treatment dropout. Results indicate that a higher salivary cortisol level in response to stress is associated with an inability to remain in substance abuse treatment. These findings are the first to document a biological marker of stress as a predictor of substance abuse treatment dropout, and support the development and implementation of treatments targeting this vulnerability.

1. Determine whether stress in preterm infants, measured with salivary cortisol, decreases after five days of Kangaroo Care (KC) compared to five days of Standard Care (SC). 2. To determine whether kangaroo care provides sustainable pain relief beyond the period of skin-to-skin holding. Preterm infants (n = 38) born at 27-30 weeks gestational age were randomized to either the KC or the SC group and received the allocated intervention starting on day of life (DOL) five and continuing for five days. Salivary cortisol was collected on DOL five and again on DOL ten. Differences were analyzed using repeated measures ANOVA and t tests. Pain during nasal suctioning over five days was assessed using the Premature Infant Pain Profile (PIPP). 1. Adequate saliva samples for salivary cortisol were collected for 13 KC infants and 11 SC infants. There was no main effect of group (p = 0.49), but there was a significant main effect of age (DOL five versus DOL ten), with salivary cortisol levels decreasing in both groups (p = 0.02). 2. Pain scores for both groups (n = 38) indicted mild to moderate pain during suctioning, with no significant difference in pain scores between groups. 1. KC did not affect salivary cortisol levels in preterm neonates, but levels in both the KC and SC groups decreased over time from DOL five to ten. Salivary cortisol may vary with age of infant. 2. Infants experience pain during routine suctioning and may require pain management.

Stress-induced structural remodeling in hippocampus: Prevention by lithium treatment

Chronic restraint stress, psychosocial stress, as well as systemic or oral administration of the stress-hormone corticosterone induces a morphological reorganization in the rat hippocampus, in which adrenal steroids and excitatory amino acids mediate a reversible remodeling of apical dendrites on CA3 pyramidal cell neurons of the hippocampus. This stress-induced neuronal remodeling is accompanied also by behavioral changes, some of which can be prevented with selective antidepressant and anticonvulsive drug treatments. Lithium is an effective treatment for mood disorders and has neuroprotective effects, which may contribute to its therapeutic properties. Thus, we wanted to determine whether lithium treatment could prevent the effects of chronic stress on CA3 pyramidal cell neuroarchitecture and the associated molecular and behavioral measures. Chronic lithium treatment prevented the stress-induced decrease in dendritic length, as well as the stress-induced increase in glial glutamate transporter 1 (GLT-1) mRNA expression and the phosphorylation of cAMP-response element binding in the hippocampus. Lithium treatment, however, did not prevent stress effects on behavior in the open field or the plus-maze. These data demonstrate that chronic treatment with lithium can protect the hippocampus from potentially deleterious effects of chronic stress on glutamatergic activation, which may be relevant to its therapeutic efficacy in the treatment of major depressive disorder and bipolar disorder.

By interpreting disasters as opportunities to initiate the fulfilment of development needs, realise the vulnerability of the affected community and environment, and extend the legacy of relief funds and effort, this paper builds upon the concept linking relief, rehabilitation and development (LRRD) in the sanitation sector. It aims to use a composite of case studies to devise a framework for a semi-hypothetical scenario to identify critical components and generic processes for a LRRD action plan. The scenario is based on a latrine wetland sanitation system in a Muslim community. Several sub-frameworks are developed: (i) latrine design; (ii) assessment of human waste treatment; (iii) connective sanitation promotion strategy; and (iv) ecological systems and environmental services for sanitation and development. This scenario illustrates the complex issues involved in LRRD in sanitation work and provides technical notes and references for a legacy plan for disaster relief and development. © 2015 The Author(s).

Abdominal pain is difficult to treat in patients with chronic pancreatitis (CP). Medical therapy including antioxidants has been shown to relieve pain of CP in the short-term. Our aim was to study the long-term results of optimized medical and interventional therapy for pain relief in patients with CP with a step-up approach. All consecutive patients with CP were included prospectively in the study. They were treated medically with a well-balanced diet, pancreatic enzymes, and antioxidants (9000 IU beta-carotene, 0.54 g vitamin C, 270 IU vitamin E, 600 µg organic selenium, and 2 g methionine). Endoscopic therapy and/or surgery were offered if medical therapy failed. Pain relief was the primary outcome measure. A total of 313 patients (mean age 26.16 ± 12.17; 244 males) with CP were included; 288 (92%) patients had abdominal pain. The etiology of CP was idiopathic in 224 (71.6%) and alcohol in 82 (26.2%). At 1-year follow-up, significant pain relief was achieved in 84.7% of patients: 52.1% with medical therapy, 16.7% with endoscopic therapy, 7.6% with surgery, and 8.3% spontaneously. The mean pain score decreased from 6.36 ± 1.92 to 1.62 ± 2.10 (P < 0.001). Of the 288 patients, 261, 218, 112, and 51 patients were followed up for 3, 5, 10, and 15 years, respectively; 54.0%, 57.3%, 60.7%, and 68.8% of them became pain free at those follow-up periods. Significant pain relief is achieved in the majority of patients with optimized medical and interventional treatment. © 2016 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

To perform a systematic review of randomised controlled trials of all psychological treatments except eye movement desensitisation and reprocessing following the guidelines of the Cochrane Collaboration. Systematic searches of computerised databases, hand search of the Journal of Traumatic Stress, searches of reference lists, known websites and discussion fora, and personal communication with key workers. Types of studies - Any randomised controlled trial of a psychological treatment. Types of participants - Adults suffering from traumatic stress symptoms for three months or more. Types of interventions - Trauma-focused cognitive behavioural therapy/exposure therapy (TFCBT); stress management (SM); other therapies (supportive therapy, non-directive counselling, psychodynamic therapy and hypnotherapy); group cognitive behavioural therapy (group CBT). Types of outcomes - Severity of clinician rated traumatic stress symptoms. Secondary measures included self-reported traumatic stress symptoms, depressive symptoms, anxiety symptoms, adverse effects and dropouts. Data was entered using the Review Management software. Quality assessments were performed. The data were analysed for summary effects using the RevMan 4.2 programme. Twenty-nine studies were included in the review. With regards to reduction of clinician assessed PTSD symptoms TFCBT did significantly better than waitlist/usual care (standardised mean difference (SMD) = -1.36; 95% CI, -1.88 to -0.84; 13 studies; n = 609). There was no significant difference between TFCBT and SM (SMD = -0.27; 95% CI, -0.71 to 0.16; 6 studies; n = 239).

This study assessed the efficacy and safety of guaifenesin 600 mg and pseudoephedrine hydrochloride 60 mg extended-release bilayer tablets in providing relief of acute respiratory symptoms when used as an adjunct to antibiotics in patients with an acute respiratory infection (ARI). Adult patients experiencing symptoms of ARI and meeting the physician's usual diagnostic criteria for oral antibiotic treatment were prescribed an antibiotic and randomized to adjunctive guaifenesin/pseudoephedrine hydrochloride or matching placebo twice daily for 7 days. Patients completed symptom diaries and treatment assessments twice daily and attended office visits on Days 4 and 8. The safety/intent-to-treat (ITT) population analysis included 601 patients (guaifenesin/pseudoephedrine, n = 303; placebo, n = 298). Mean symptom scores were lower with guaifenesin/pseudoephedrine from Day 3 for every symptom assessed, with statistically significant improvements in total symptom score from Day 3 (P = 0.026). The greatest effects of treatment with guaifenesin/pseudoephedrine were observed for nasal congestion and sinus headache. Time to overall relief was shorter with guaifenesin/pseudoephedrine (P = 0.038). Significantly more patients reported "the medication was helping during the day" on Day 2 with guaifenesin/pseudoephedrine (P = 0.002). Patient assessments of symptom relief showed a significant preference for guaifenesin/pseudoephedrine versus placebo (P = 0.021). Treatment with guaifenesin/pseudoephedrine was well tolerated. Insomnia (2.6%), nausea (2.3%), and headache (1.3%) were the most common treatment-related adverse effects. As adjunctive therapy for symptom relief for patients taking antibiotics for ARIs, guaifenesin/pseudoephedrine shortened time to relief and improved bothersome respiratory symptoms better than placebo, with greatest effects seen for nasal congestion and sinus headache.

To develop and test the safety and effectiveness of an acupressure garment (the Relief Brief) in decreasing the pain and symptom distress associated with dysmenorrhea. A randomized clinical trial applied a 2 (Relief Brief use or control group) x 3 (baseline and two treatment measurement occasions) mixed factorial design. Sixty-one (61) women with moderately severe primary dysmenorrhea were randomly assigned to the standard treatment control group or the Relief Brief acupressure device group after one pretreatment menses, with 58 women reporting the effect on their pain during two post-treatment menstrual cycles. The acupressure garment: The Relief Brief is a cotton Lycra panty brief with a fixed number of lower abdominal and lower back latex foam acupads that provide pressure to dysmenorrhea-relieving Chinese acupressure points. Menstrual pain severity (worst pain and symptom intensity), pain medication use, and adverse effects were analyzed using between-groups and repeated measures analyses of treatment effects. Statistical and clinical significance criteria were applied a priori. For pain measures and pain medication use, the group main effect, time main effect and group x time interaction were statistically significant. Median pain medication use, the same for both groups at baseline (6 pills per day), dropped to 2 pills per day for the Relief Brief group but remained at 6 pills for the control group at the second treatment cycle. Predicted clinical significance criteria were surpassed: almost all (90%) women wearing the Relief Brief obtained at least a 25% reduction in menstrual pain severity (a 2-3 point drop) compared to only 8% of the control group (z = 6.07; p < 0.05). Relief Brief use was associated with at least a 50% decline in menstrual pain symptom intensity in more than two thirds of the women. An acupressure device is an effective and safe nonpharmacologic strategy for the treatment of primary dysmenorrhea. With design modifications, it could serve

2013-01-01

Background Many people with sore throat seek, and are often inappropriately prescribed, antibiotics. Aim The objective of this study was to determine the analgesic efficacy of flurbiprofen 8.75 mg microgranules versus placebo. These microgranules are a possible alternative treatment for patients with sore throat due to upper respiratory tract infection (URTI). Design and setting Randomised, double-blind, placebo-controlled, multiple-dose study conducted at eight primary care sites in Australia. Method Participants with sore throat of onset within the past 4 days received either flurbiprofen 8.75 mg microgranules or non-medicated placebo microgranules. Throat soreness, difficulty in swallowing, sore throat pain intensity, sore throat relief, oral temperature, and treatment benefits were all assessed at regular intervals. Result Of 373 patients from eight centres, 186 received flurbiprofen 8.75 mg microgranules and 187 received placebo microgranules (intent-to-treat population). Throat soreness was significantly reduced over the first 2 hours after the first dose. Reductions in difficulty in swallowing were observed at all time points from 5 to 360 minutes after the first dose, after taking flurbiprofen microgranules versus placebo. Sore throat relief was also evident at 1 minute and lasted for at least 6 hours. The multiple-dose efficacy results showed reduction of difficulty in swallowing at the end of days 1–3 and sore throat relief at the end of day 1. Conclusion Microgranules containing flurbiprofen 8.75 mg provided fast and effective relief from sore throat due to URTI and represent an alternative treatment option to antibiotic therapy.

A prime concern for gastroesophageal reflux disease (GERD) patients is fast symptom control. Sparse valid information is available on the rapidity of the effect of proton pump inhibitors in providing symptom relief. The new reflux questionnaire ReQuest is validated for daily assessment of changes in GERD symptoms. Therefore, this study investigated the efficacy of 20 mg pantoprazole and 20 mg esomeprazole with regard to the time to symptom relief in patients with endoscopy-negative GERD (enGERD) using ReQuest. 529 patients were treated with pantoprazole or esomeprazole over 4 weeks. ReQuest symptom scores were assessed daily. The mean and median times to first and sustained symptom relief were determined. Median time to first symptom relief was 2 days for both drugs (intention-to-treat population). The median time to sustained symptom relief was 3 days shorter with pantoprazole (10.0 vs. 13.0 days). The Hodges-Lehmann estimator for the difference in time to reach first and sustained symptom relief between both groups was 0.00 days. For both variables the one-sided 95% CI (Moses) was [0.00; infinity[, documenting no significant differences between the treatment groups. The rapidity of symptom control can be evaluated by clinically significant parameters using ReQuest. Pantoprazole and esomeprazole are equally effective in the time to first and sustained symptom relief. Copyright 2007 S. Karger AG, Basel.

To assess the incidence or prevalence of opioid dependence syndrome in adults (with and without previous history of substance abuse) following treatment with opioid analgesics for pain relief. Medline, Embase, CINHAL and the Cochrane Library were searched up to January 2011. Systematic reviews and primary studies were included if they reported data about incidence or prevalence of opioid dependence syndrome (as defined by DSM-IV or ICD-10) in patients receiving strong opioids (or opioid-type analgesics) for treatment of acute or chronic pain due to any physical condition. The data were abstracted, and the methodological quality was assessed using validated checklists. Data were extracted from 17 studies involving a total of 88 235 participants. The studies included three systematic reviews, one randomized controlled trial, eight cross-sectional studies and four uncontrolled case series. Most studies included adult patients with chronic non-malignant pain; two also included patients with cancer pain; only one included patients with a previous history of dependence. Incidence ranged from 0 to 24% (median 0.5%); prevalence ranged from 0 to 31% (median 4.5%). The available evidence suggests that opioid analgesics for chronic pain conditions are not associated with a major risk for developing dependence. © 2012 The Authors, Addiction © 2012 Society for the Study of Addiction.

Relief from anxiety using complementary therapies in the perioperative period: A principle-based concept analysis.

2016-08-01

To analyze and clarify the concept of providing relief from anxiety using complementary therapies in the perioperative period utilizing the epistemological, pragmatic, linguistic and logical principles of a principle-based concept analysis to examine the state of the science. The majority of patients scheduled for surgery experience anxiety in the perioperative period. Anxiety has the potential to limit a patient's ability to participate in his or her care throughout their hospitalization. Although medications are the conventional medical treatment for anxiety in the perioperative period, the addition of a complementary therapy could be an effective holistic approach to providing relief from anxiety. Principle-based concept analysis. In 2015, strategic literature searches of CINHAL and PUBMED using keywords were performed. Fifty-six full text articles were assessed for eligibility. Twelve studies were used in the final analysis to clarify the concept of relief from anxiety using complementary therapies in the perioperative period. This analysis has clarified the maturity and boundaries, within the four principles of a principle-based concept analysis, of the concept of relief from anxiety using complementary therapies in the perioperative period. A greater understanding of relief from anxiety using complimentary therapies in the perioperative period as an adjunct to conventional medicine will allow perioperative nurses and anesthesia providers to modify and specify the plan of care for their surgical patients. The use of complementary therapies for relief in the perioperative period appears to be an area of promising research and treatment for patients, families and providers.

Oliveira, N C A C; Santos, J L F; Linhares, M B M

2017-01-01

Pain is a stressful experience that can have a negative impact on child development. The aim of this crossover study was to examine the efficacy of audiovisual distraction for acute pain relief in paediatric inpatients. The sample comprised 40 inpatients (6-11 years) who underwent painful puncture procedures. The participants were randomized into two groups, and all children received the intervention and served as their own controls. Stress and pain-catastrophizing assessments were initially performed using the Child Stress Scale and Pain Catastrophizing Scale for Children, with the aim of controlling these variables. The pain assessment was performed using a Visual Analog Scale and the Faces Pain Scale-Revised after the painful procedures. Group 1 received audiovisual distraction before and during the puncture procedure, which was performed again without intervention on another day. The procedure was reversed in Group 2. Audiovisual distraction used animated short films. A 2 × 2 × 2 analysis of variance for 2 × 2 crossover study was performed, with a 5% level of statistical significance. The two groups had similar baseline measures of stress and pain catastrophizing. A significant difference was found between periods with and without distraction in both groups, in which scores on both pain scales were lower during distraction compared with no intervention. The sequence of exposure to the distraction intervention in both groups and first versus second painful procedure during which the distraction was performed also significantly influenced the efficacy of the distraction intervention. Audiovisual distraction effectively reduced the intensity of pain perception in paediatric inpatients. The crossover study design provides a better understanding of the power effects of distraction for acute pain management. Audiovisual distraction was a powerful and effective non-pharmacological intervention for pain relief in paediatric inpatients. The effects were

The purpose of this study was to compare the rate of symptom relief to functional improvement and examine the relationships between symptom relief and functional improvement during the acute phase of treatment. A total of 131 acutely ill inpatients with major depressive disorder were enrolled to receive 20mg of fluoxetine daily for 6 weeks. Symptom severity, using the 17-item Hamilton Depression Rating Scale (HAMD-17), and functioning, using the Modified Work and Social Adjustment Scale (MWSAS), were measured regularly. The outcome measures were the HAMD-17 score and MWSAS score at weeks 1, 2, 3, 4, and 6. We compared the effect size and the reduction rate of HAMD-17 to those of MWSAS at week 1, 2, 3, 4, and 6. Structural equation modeling was used to examine relationships among the study variables. Of the 131 participants, 126 had at least one post-baseline assessment at week 1 and were included in the analysis. The HAMD-17 had a larger effect size and reduction rate than the MWSAS at weeks 1, 2, 3, 4, and 6. Parsimonious model satisfied all indices of goodness-of-fit (Chi-Square/df=1.479, TLI=0.978, CFI=0.986, RMSEA=0.062) and had all paths with significant path coefficients. MWSAS at week 0 predicted HAMD-17 at week 1. This was an open-labeled study with small sample size. Depressive symptoms improved more quickly than functioning during the acute phase of treatment. Depressive symptoms and functional impairment are distinct domains, and should be assessed independently. Copyright © 2015 Elsevier B.V. All rights reserved.

2017-08-01

Few studies have assessed the underlying theoretical components of the Common Sense Model. Past studies have found, through implicit priming, that coping strategies are embedded within illness schema. Our aim was to evaluate the effect priming 'headache' illness schema upon attentional engagement to pain relief medication and to examine the interaction with illness treatment beliefs. Attentional engagement to the pain relief medication ('Paracetamol') was assessed using a 2 (primed vs. control) × 2 (strong belief in medication efficacy vs. weak belief in medication efficacy) design. During a grammatical decision task (identifying verbs/non-verbs), participants were randomised to receive a headache prime or a control. Response latency to the target word, 'Paracetamol' was the dependent variable. 'Paracetamol' treatment beliefs were determined using the brief illness perception questionnaire. Sixty-three participants completed the experiment. There was a significant interaction between illness-primed vs. control and high vs. low treatment efficacy of Paracetamol (p < .001), suggesting an attentional disengagement effect to the coping strategy in illness-primed participants whom held stronger treatment beliefs regarding the efficacy of Paracetamol. In summary, implicit illness schema activation may simultaneously activate embedded coping strategies, which appears to be moderated by specific illness beliefs.

Music for pain relief.

The efficacy of music for the treatment of pain has not been established. To evaluate the effect of music on acute, chronic or cancer pain intensity, pain relief, and analgesic requirements. We searched The Cochrane Library, MEDLINE, EMBASE, PsycINFO, LILACS and the references in retrieved manuscripts. There was no language restriction. We included randomized controlled trials that evaluated the effect of music on any type of pain in children or adults. We excluded trials that reported results of concurrent non-pharmacological therapies. Data was extracted by two independent review authors. We calculated the mean difference in pain intensity levels, percentage of patients with at least 50% pain relief, and opioid requirements. We converted opioid consumption to morphine equivalents. To explore heterogeneity, studies that evaluated adults, children, acute, chronic, malignant, labor, procedural, or experimental pain were evaluated separately, as well as those studies in which patients chose the type of music. Fifty-one studies involving 1867 subjects exposed to music and 1796 controls met inclusion criteria. In the 31 studies evaluating mean pain intensity there was a considerable variation in the effect of music, indicating statistical heterogeneity ( I(2) = 85.3%). After grouping the studies according to the pain model, this heterogeneity remained, with the exception of the studies that evaluated acute postoperative pain. In this last group, patients exposed to music had pain intensity that was 0.5 units lower on a zero to ten scale than unexposed subjects (95% CI: -0.9 to -0.2). Studies that permitted patients to select the music did not reveal a benefit from music; the decline in pain intensity was 0.2 units, 95% CI (-0.7 to 0.2). Four studies reported the proportion of subjects with at least 50% pain relief; subjects exposed to music had a 70% higher likelihood of having pain relief than unexposed subjects (95% CI: 1.21 to 2.37). NNT = 5 (95% CI: 4 to 13). Three

Design and development of a smart knee pain relief pad based on vibration and alternate heating and cooling treatments.

2018-03-28

Knee pain is one of the main health issue faced by different people in the different parts of the world. Over one fourth of the people above the age of fifty suffer from knee pain. Though there are several physiotherapy treatments for treating knee pain they are not self-applicable and those which are self-applicable by the patient are not highly efficient. This paper deals with an approach towards the use of combining two effective physiotherapy treatments which includes vibrations at acupressure points on knee and alternate heating and cooling treatments. These treatments are controlled using a smart phone in which the user can choose their setting depending on intensity and places of pain. The knee pad controlled using the smart phone serves as a self-applicable and effective knee pain treatment especially for the elderly. Heating and cooling combination therapy will be a suitable alternative for treatment of musculoskeletal diseases, decrease muscle spasms, muscular pain/tension and also increase the speed of nerve conduction, thus improving range of motion. This methodology also helps to relief the sinusitis pain, chronic low back pain and muscular sprain in athletes.

Characterization of Machine Variability and Progressive Heat Treatment in Selective Laser Melting of Inconel 718

The absence of an economy of scale in spaceflight hardware makes additive manufacturing an immensely attractive option for propulsion components. As additive manufacturing techniques are increasingly adopted by government and industry to produce propulsion hardware in human-rated systems, significant development efforts are needed to establish these methods as reliable alternatives to conventional subtractive manufacturing. One of the critical challenges facing powder bed fusion techniques in this application is variability between machines used to perform builds. Even with implementation of robust process controls, it is possible for two machines operating at identical parameters with equivalent base materials to produce specimens with slightly different material properties. The machine variability study presented here evaluates 60 specimens of identical geometry built using the same parameters. 30 samples were produced on machine 1 (M1) and the other 30 samples were built on machine 2 (M2). Each of the 30-sample sets were further subdivided into three subsets (with 10 specimens in each subset) to assess the effect of progressive heat treatment on machine variability. The three categories for post-processing were: stress relief, stress relief followed by hot isostatic press (HIP), and stress relief followed by HIP followed by heat treatment per AMS 5664. Each specimen (a round, smooth tensile) was mechanically tested per ASTM E8. Two formal statistical techniques, hypothesis testing for equivalency of means and one-way analysis of variance (ANOVA), were applied to characterize the impact of machine variability and heat treatment on six material properties: tensile stress, yield stress, modulus of elasticity, fracture elongation, and reduction of area. This work represents the type of development effort that is critical as NASA, academia, and the industrial base work collaboratively to establish a path to certification for additively manufactured parts.

OBJECTIVE: To compare pre-hospital parental administration of pain relief for children with that of the accident and emergency (A&E) department staff and to ascertain the reason why pre-hospital analgesia is not being given. DESIGN/METHODS: An anonymous prospective questionnaire was given to parents/guardians of children < 17 years. The children were all self referred with head injuries or limb problems including burns. The first part asked for details of pain relief before attendance in the A&E department. The second part of the questionnaire contained a section for the examining doctor and triage nurse to fill in. The duration of the survey was 28 days. RESULTS: Altogether 203 of 276 (74%) of children did not receive pain relief before attendance at the A&E department. Reasons for parents not giving pain relief included 57/203 (28%) who thought that giving painkillers would be harmful; 43/203 (21%) who did not give painkillers because the accident did not happen at home; and 15/203 (7%) who thought analgesia was the responsibility of the hospital. Eighty eight of the 276 (32%) did not have any painkillers, suitable for children, at home. A&E staff administered pain relief in 189/276 (68%). CONCLUSIONS: Parents often do not give their children pain relief before attending the A&E department. Parents think that giving painkillers may be harmful and often do not have simple analgesics at home. Some parents do not perceive that their child is in pain. Parents require education about appropriate pre-hospital pain relief for their children. PMID:10417932

The objective of the present study was to investigate the relationship between masticatory function-related factors (masticatory performance, occlusal contact area, maximum bite force, number of chewing strokes, and muscle activity) and the stress-relieving effects of chewing. A total of 28 healthy male subjects were instructed to rest or chew for 10min after 30min of stress loading with arithmetic calculations. Their stress state was assessed by measuring salivary cortisol levels. Saliva was collected at three time points: before stress loading, immediately after stress loading, and 10min after stress loading. Compared to resting, chewing produced a significantly greater reduction in the rate of change in salivary cortisol levels 10min after stress loading. A negative correlation was observed between the rate of decrease in salivary cortisol levels and the number of chewing strokes. No significant correlation was observed between the rate of decrease in salivary cortisol levels and other measurement items. In healthy dentulous people, the number of chewing strokes has been shown to be a masticatory function-related factor that affects stress relief from chewing, suggesting the possibility that more appropriate chewing would produce a greater effect psychological stress relief.

Effect of laser on pain relief and wound healing of recurrent aphthous stomatitis: a systematic review.

PubMed

Suter, Valerie G A; Sjölund, Sophia; Bornstein, Michael M

2017-05-01

The aim of this systematic review was to assess a potential benefit of laser use in the treatment of recurrent aphthous stomatitis (RAS). The primary outcome variables were pain relief, duration of wound healing and reduction in episode frequency. A PICO approach was used as a search strategy in Medline, Embase and Cochrane databases. After scanning and excluding titles, abstracts and full texts, 11 studies (ten RCTs and one non-randomised controlled trial) were included. Study selection and data extraction was done by two observers. Study participants varied between 7-90 for the laser and 5-90 for the control groups. Laser treatment included Nd:YAG laser ablation, CO 2 laser applied through a transparent gel (non-ablative) and diode laser in a low-level laser treatment (LLLT) mode. Control groups had placebo, no therapy or topical corticosteroid treatment. Significant pain relief immediately after treatment was found in five out of six studies. Pain relief in the days following treatment was recorded in seven studies. The duration of RAS wound healing was also reduced in five studies. However, criteria of evaluation differed between the studies. The episode frequency was not evaluated as only one study addressed this outcome parameter, but did not discriminate between the study (LLLT) and control (corticosteroid) groups. Jadad scores (ranging from 0 to 5) for quality assessment of the included studies range between 0 and 2 (mean = 1.0) for studies analysing pain relief and between 0 and 3 (mean = 1.1) for studies evaluating wound healing. The use of lasers (CO 2 laser, Nd:YAG laser and diode laser) to relieve symptoms and promote healing of RAS is a therapeutic option. More studies for laser applications are necessary to demonstrate superiority over topical pharmaceutical treatment and to recommend a specific laser type, wavelength, power output and applied energy (ablative versus photobiomodulation).

This study aimed to analyse the injuries sustained by rescue workers in earthquake relief efforts in high altitude areas for improving the ways of how to effectively prevent the injuries. The clinical data of 207 relief workers from four military hospitals in Tibet, who were injured in the Tibetan disaster areas of China during '4.25' Nepal earthquake rescue period, was retrospectively analyzed. The demographic features, sites of injury and causes of injury were investigated. The most frequently injured sites were the ankle-foot and hand-wrist (n = 61, 26.5 %), followed by injuries in leg-knee-calf (n = 22, 9.6 %), head-neck (4.87 %), thoracic and abdominal region (2.6 %) and lower back (3.9 %). The specific high-altitude environment increased the challenges associated with earthquake relief. The specific plateau environment and climate increased the burden and challenge in earthquake relief. The injury distribution data shown in this study demonstrated that effective organization and personnel protection can reduce the injury occurrences. Relief workers were prone to suffering various injuries and diseases under specific high-altitude environment.

Stress and pain relief in the care of the surgical neonate.

PubMed

Currie, John M

2008-11-01

In recent years, there has been a major change in our thinking about the way neonates experience stress. This understanding has led to advances in anesthetic technique and the pre- and postoperative care of the surgical neonate. Stress can develop before birth due to placental insufficiency. This can lead to preterm delivery, and the preterm infant is much more vulnerable to stressful stimulus. Stress is detrimental to the neonate in the short term and can also have adverse effects on the future wellbeing of the child. Limiting stress is not just about good pain control. The nursing environment is vitally important. Much can be achieved with good attention to detail in this respect. The effects of stress and the ways they can be minimized are discussed.

Simplifying study of fever's dramatic relief of autistic behavior.

PubMed

Good, Peter

2017-02-01

Dramatic relief of autistic behavior by infectious fever continues to tantalize parents and practitioners, yet researchers still hesitate to study its physiology/biochemistry, fearing stress and heat of brain imaging, contagion, and fever's complexity. Yet what could be more revealing than a common event that virtually 'normalizes' autistic behavior for a time? This paper proposes study of three simplified scenarios: (1) improvements appearing hours before fever, (2) return of autistic behavior soon after fever, (3) improvements persisting long after fever. Each scenario limits some risk - and some explanation - inviting triangulation of decisive factor(s) in relief and recurrence. Return of autistic behavior after fever may be most revealing. The complex mechanisms that generated fever have all abated; simpler cooling mechanisms prevail - how many plausible explanations can there be? The decisive factor in fever's benefit is concluded to be water drawn/carried from brain myelin and astrocytes by osmolytes glutamine and taurine released from muscles and brain; the decisive factor in return of autistic behavior after fever is return of water.

Hydrogen gas relief valve

DOEpatents

Whittlesey, Curtis C.

1985-01-01

An improved battery stack design for an electrochemical system having at least one cell from which a gas is generated and an electrolyte in communication with the cell is described. The improved battery stack design features means for defining a substantially closed compartment for containing the battery cells and at least a portion of the electrolyte for the system, and means in association with the compartment means for selectively venting gas from the interior of the compartment means in response to the level of the electrolyte within the compartment means. The venting means includes a relief valve having a float member which is actuated in response to the level of the electrolyte within the compartment means. This float member is adapted to close the relief valve when the level of the electrolyte is above a predetermined level and open the relief valve when the level of electrolyte is below this predetermined level.

Marital stability and repartnering: infertility-related stress trajectories of unsuccessful fertility treatment.

To compare the trajectories of infertility-related stress between patients who remain in the same relationship and patients who repartner. Longitudinal cohort study using latent growth modeling. Fertility centers. Childless men and women evaluated before starting a new cycle of fertility treatment and observed for a 5-year period of unsuccessful treatments. None. Marital stability and infertility-related stress. The majority of patients (86%) remained with their initial partner, but 14% of participants separated and repartnered while pursuing fertility treatments. Marital stability significantly predicted the initial status of infertility stress and infertility stress growth levels. Specifically, patients who repartnered had higher infertility stress levels at all time points compared with those who remained in the same relationship, regardless of the partner they were with at assessment. Furthermore, results showed an increasing stress trajectory over time for those who repartnered, compared with those who remained in a stable relationship. Men and women in fertility treatment who form a second union have higher initial levels of stress in their original relationship and higher changes in stress levels over the course of treatments. These findings suggest that high infertility-related stress levels before entering fertility treatment can negatively affect the stability of marital relationships and lead to repartnering.

Roy, Anuja N; Madhavan, S Suresh; Lloyd, Andrew

2015-04-01

Insomnia is a burdensome, commonly comorbid condition. How patients value various aspects of the safety and efficacy of available drugs has not been studied. The aim of the present study was to quantify patient-rated utility by studying willingness to pay (WTP) for attributes of symptom relief via a discrete choice experiment (DCE). Adult primary care patients (West Virginia University Hospital) with comorbid insomnia were enrolled. The attributes and levels examined were sleep onset latency (SOL; 10, 20,30 minutes), awakenings (1, 2, 3), wake time after sleep onset (WASO; 15,45, 60 minutes), total sleep time (TST; 6, 7, 8 hours), hangover (none, mild, moderate), FDA-approved duration of use (short term, not restricted to short term, no restrictions), and out-of-pocket cost per month ($20, $35, $50). Willingness to pay (WTP) data were analyzed using a random effects binary logistic regression model. A total of 82 patients completed the DCE (74 analyzed). SOL, WASO, TST, and cost were all found to predict treatment choice. Higher values of SOL, WASO, and cost resulted in decreased preference for a particular treatment, while higher TST predicted increased preference. Modeling revealed an estimated marginal WTP of $66.69 for an example product that improved SOL by 10 minutes, reduced WASO by 15 minutes, and improved TST by 1 hour. Patient WTP for symptomatic relief in insomnia can help clinicians fine-tune interventions based on patient preferences, provide evidence for drug formulary and reimbursement decisions, and potentially guide the development of novel drugs.

Buckling analysis of stiff thin films suspended on a substrate with tripod surface relief structure

Yu, Qingmin; Chen, Furong; Li, Ming; Cheng, Huanyu

2017-09-01

A wavy configuration is a simple yet powerful structural design strategy, which has been widely used in flexible and stretchable electronics. A buckled structure created from a prestretch-contact-release process represents an early effort. Substrates with engineered surface relief structures (e.g., rectangular islands or tripod structure) have enabled stretchability to the devices without sacrificing their electric performance (e.g., high areal coverage for LEDs/photovoltaics/batteries/supercapacitors). In particular, the substrate with a tripod surface relief structure allows wrinkled devices to be suspended on a soft tripod substrate. This minimizes the contact area between devices and the deformed substrate, which contributes to a significantly reduced interfacial stress/strain. To uncover the underlying mechanism of such a design, we exploit the energy method to analytically investigate the buckling and postbuckling behaviors of stiff films suspended on a stretchable polymeric substrate with a tripod surface relief structure. Validated by finite element analysis, the predications from such an analytical study elucidate the deformed profile and maximum strain in the buckled and postbuckled stiff thin device films, providing a useful toolkit for future experimental designs.

Examining the Value of Menopausal Symptom Relief Among US Women.

PubMed

Craig, Benjamin M; Mitchell, Sandra A

2016-01-01

Menopausal symptoms can cause significant distress to women, yet little is known about the value women place on these symptoms. In April 2013, 3397 US women, aged 40 to 69 years, completed an online survey that included 30 paired comparisons. Specifically, respondents were shown two menopausal symptoms described using the Patient-Reported Outcomes Version of the Common Terminology Criteria for Adverse Events and asked, "Which do you prefer?" From their choices, we estimated a generalized linear model to assess the values women place on symptom relief in terms of quality-adjusted life-years (QALYs). Approximately half the respondents (1753 of 3397 [52%]) always preferred a reduced lifespan (up to 90 days) instead of experiencing menopausal symptoms at their worst for 30 days. For most of the symptoms (248 of 263 [94%]), including low-grade events, QALYs were significantly reduced (P < 0.05). The value women placed on relief ranged widely by symptom domain: the relief from depression, problems with memory, headache, pain in abdomen, problems with anger, and vomiting were the most valuable. Overall, the value women place on menopausal symptom relief is surprisingly high. As the first national study to directly ask women about their preferences and to estimate the value of menopausal symptom relief on a QALY scale, this work provides critical evidence for health outcomes research in midlife women and can be applied in the evaluation of treatments that reduce or eliminate menopausal symptoms. This work also provides proof-of-concept for an approach to value Patient-Reported Outcomes Version of the Common Terminology Criteria for Adverse Events responses on a QALY scale.

[Options for stress management in obesity treatment].

PubMed

Czeglédi, Edit

2016-02-14

Overeating and physical inactivity are of great importance in the etiology of obesity. Psychological factors are often found in the background of life style. Chronic stress can contribute to physical inactivity and behaviors that hinder the keeping of a diet (e.g., irregular eating pattern, emotional eating). Results of randomized controlled trials show that relaxation can reduce emotional eating, improve cognitive restraint, and thereby reduce weight. However, stress management is more than relaxation. It consists of adaptive emotion-focused and problem-focused coping strategies and skills to improve relationships. Deflection skills may help in replacing emotional eating with other behaviors. Cognitive restructuring, saying no, and problem solving help to prevent or manage conflicts and difficulties otherwise would result in overeating due to distress. Developing stress management skills may result in greater compliance with the treatment. The techniques presented in the study can be easily applied by general practitioners or specialists, and provide tools for optimizing obesity treatment.

Experiences in disaster-related mental health relief work: An exploratory model for the interprofessional training of psychological relief workers.

PubMed

Ren, ZhengJia; Wang, HongTao; Zhang, Wei

2017-01-01

The purpose of this study was to begin to generate an exploratory model of the disaster-related mental health education process associated with the training experiences of psychological relief workers active during the Sichuan earthquake in China. The data consisted of semi-structured interviews with 20 psychological relief workers from four different professions (social workers, psychiatric nurses, psychiatrists, and counsellors) regarding their experiences in training and ideas for improvement. The model explains the need to use a people-centred community interprofessional education approach, which focuses on role-modelling of the trainer, caring for relief workers, paying attention to the needs of the trainee, and building systematic interprofessional education strategies. The proposed model identifies areas for the comprehensive training of relief workers and aims to address the importance of people-centred mental health service provisions, ensure intentional and strategic training of relief workers using interprofessional concepts and strategies, and use culturally attuned and community-informed strategies in mental health training practices.

2011-01-01

This study investigates the prevalence of self-medication among undergraduate nursing students seeking to relieve pain and characterizes the pain and relief obtained through the used medication. This epidemiological and cross-sectional study was carried out with 211 nursing students from a public university in Goiás, GO, Brazil. A numerical scale (0-10) measured pain intensity and relief. The prevalence of self-medication was 38.8%. The source and main determining factor of this practice were the student him/herself (54.1%) and lack of time to go to a doctor (50%), respectively. The most frequently used analgesic was dipyrone (59.8%) and pain relief was classified as good (Md=8.5;Max=10;Min=0). The prevalence of self-medication was higher than that observed in similar studies. Many students reported that relief obtained through self-medication was good, a fact that can delay the clarification of a diagnosis and its appropriate treatment.

Introduction: An increased production of oxidizing species related to reactive oral diseases, such as chronic apical periodontitis, could have systemic implications such as an increase in cardiovascular morbidity. Based on this consideration, we conducted a prospective study to assess whether subjects affected by chronic periodontitis presented with higher values of oxidative stress than reference values before endodontic treatment, and whether endodontic treatment can reduce the oxidative imbalance and bring it back to normal in these subjects. Materials and methods: The authors recruited 2 groups of patients from private studies and dental clinics: these patients were recruited randomly. The oxidative balance in both patients with chronic apical periodontitis (CAP) and healthy control patients was determined by measuring the oxidant status, using an identification of the reactive oxygen metabolites (d-ROMs) test, while the antioxidant status in these patients was determined using a biological antioxidant potential (BAP) test. Both these tests were carried on plasma samples taken from enrolled patients. Values were measured both before the endodontic treatment of the patients with chronic apical periodontitis, and 30 and 90 days after treatment, and compared to those obtained from healthy control patients. Results: It was found that, on recruitment, the patients with chronic apical periodontitis exhibited significantly higher levels of oxidative stress than control patients, as determined by the d-ROMs and BAP tests. Furthermore, the d-ROMs test values were shown to decrease and the BAP test values to increase over time in patients with chronic apical periodontitis following endodontic therapy. As the levels of oxidative stress in these patients tended to reduce and return to normal by 90 days following treatment. Conclusions: This study has demonstrated a positive association between chronic apical periodontitis and oxidative stress. Subjects affected by chronic

The "Tuberculosis Relief Belt Supporting Project (Tuberculosis Patient Management Project for Poverty Groups)" is a national program for socioeconomically vulnerable tuberculosis (TB) patients. We sought to evaluate the clinical and socioeconomic characteristics of poverty-stricken TB patients, and determined the need for relief. We examined in-patients with TB, who were supported by this project at the National Medical Center from 2014 to 2015. We retrospectively investigated the patients' socioeconomic status, clinical characteristics, and project expenditures. Fifty-eight patients were enrolled. Among 55 patients with known income status, 24 (43.6%) had no income. Most patients (80%) lived alone. A total of 48 patients (82.8%) had more than one underlying disease. More than half of the enrolled patients (30 patients, 51.7%) had smear-positive TB. Cavitary disease was found in 38 patients (65.5%). Among the 38 patients with known resistance status, 19 (50%) had drug-resistant TB. In terms of disease severity, 96.6% of the cases had moderate-to-severe disease. A total of 14 patients (26.4%) died during treatment. Nursing expenses were supported for 12 patients (20.7%), with patient transportation costs reimbursed for 35 patients (60%). In terms of treatment expenses for 31 people (53.4%), 93.5% of them were supported by uninsured benefits. Underlying disease, infectivity, drug resistance, severity, and death occurred frequently in socioeconomically vulnerable patients with TB. Many uninsured treatment costs were not supported by the current government TB programs, and the "Tuberculosis Relief Belt Supporting Project" compensated for these limitations. Copyright©2018.

Influence of early stress on memory reconsolidation: Implications for post-traumatic stress disorder treatment

PubMed Central

Birmes, Philippe; Ferry, Barbara

2018-01-01

Post-traumatic stress disorder (PTSD) is a common consequence of exposure to a life-threatening event. Currently, pharmacological treatments are limited by high rates of relapse, and novel treatment approaches are needed. We have recently demonstrated that propranolol, a β-adrenergic antagonist, inhibited aversive memory reconsolidation in animals. Following this, in an open-label study 70% of patients with PTSD treated with propranolol during reactivation of traumatic memory exhibited full remission. However, the reason why 30% of these patients did not respond positively to propranolol treatment is still unclear. One of the major candidates as factor of treatment resistance is the patient's early-life traumatic history. To test the role of this factor, mice with pre- or postnatal stress are being tested in fear conditioning and in a new behavioral task, the "city-like", specifically designed as a mouse model of PTSD. After reactivation of the traumatic event, mice received propranolol injection to block the noradrenergic system during memory reconsolidation. Results show that, in the “city-like” test, control mice strongly avoided the shock compartment but also the compartments containing cues associated with the electric shocks. Injection of propranolol after reactivation greatly reduced the memory of the traumatic event, but this effect was not present when mice had received pre- or postnatal stress. Moreover, propranolol produced only a very weak effect in the fear conditioning test, and never changed the corticosterone level whatever the behavioral experiment. Taken together our results suggest that our new behavioural paradigm is well adapted to PTSD study in mice, and that early stress exposure may have an impact on propranolol PTSD treatment outcome. These data are critical to understanding the effect of propranolol treatment, in order to improve the therapeutic protocol currently used in humans. PMID:29352277

Bas-Relief Modeling from Normal Images with Intuitive Styles.

PubMed

Ji, Zhongping; Ma, Weiyin; Sun, Xianfang

2014-05-01

Traditional 3D model-based bas-relief modeling methods are often limited to model-dependent and monotonic relief styles. This paper presents a novel method for digital bas-relief modeling with intuitive style control. Given a composite normal image, the problem discussed in this paper involves generating a discontinuity-free depth field with high compression of depth data while preserving or even enhancing fine details. In our framework, several layers of normal images are composed into a single normal image. The original normal image on each layer is usually generated from 3D models or through other techniques as described in this paper. The bas-relief style is controlled by choosing a parameter and setting a targeted height for them. Bas-relief modeling and stylization are achieved simultaneously by solving a sparse linear system. Different from previous work, our method can be used to freely design bas-reliefs in normal image space instead of in object space, which makes it possible to use any popular image editing tools for bas-relief modeling. Experiments with a wide range of 3D models and scenes show that our method can effectively generate digital bas-reliefs.

Stress velopharyngeal incompetence: prevalence, treatment, and management practices.

PubMed

Malick, Deonne; Moon, Jerry; Canady, John

2007-07-01

Stress velopharyngeal incompetence is the unwanted coupling of the oral and nasal cavities while brass and woodwind musicians play their instruments. This study investigated both (1) the prevalence of stress velopharyngeal incompetence in college musicians, delineating symptoms and situations possibly associated with the condition; and (2) physicians' experiences with musicians exhibiting stress velopharyngeal incompetence, including typical treatment and management techniques. Questionnaires were distributed to 297 brass or woodwind student musicians at three public universities and to 998 plastic surgeons and otolaryngologists. The musician questionnaire focused on demographic data and identification of symptoms that might indicate the presence of stress velopharyngeal incompetence. The physician questionnaire addressed demographics of the physician and his or her practice, familiarity and experience with stress velopharyngeal incompetence, and treatment and management suggestions for individuals experiencing the condition. Thirty-four percent of the responding musicians reported symptoms of stress velopharyngeal incompetence, most often after 30 minutes of playing. Forty-five percent of the responding physicians reported being familiar with the term stress velopharyngeal incompetence, although only 27% reported ever having seen a patient with the condition. The seven most frequently reported intervention strategies were referral to a speech language pathologist (47.50%), sphincter pharyngoplasty (30.00%), pharyngeal flap (26.88%), referral to a cleft palate team (24.38%), watch and wait (18.75%), posterior wall fat injection (12.50%), and palatal lift (10.00%). Stress velopharyngeal incompetence is a potentially career-ending (or career-preventing) problem that currently may be undertreated and that is in need of more systematic study both in terms of its physiologic underpinnings and its management.

The ring fingers of both hands of 44 volunteers were randomized to injection of bupivacaine with or without 1:200,000 epinephrine. The durations of time for digits to return to normal pain, touch, pressure sensation, and fingertip temperature were measured and recorded. There were three main findings: (1) the pain block of bupivacaine lasts only half as long (15 hours) as the return to normal sensation (30 hours); (2) the effect of adding epinephrine to bupivacaine prolongs the duration of pain relief in a finger block for only an additional 1.5 hours; (3) in addition to pain relief, bupivacaine finger blocks cause fingertip hyperemia with consistent significant fingertip temperature elevation that lasts 15 hours. The duration of bupivacaine pain relief is the clinically important factor that needs to be reported in bupivacaine trials. Patients should be informed that the return of pain will occur much sooner than the return of normal sensation. Adding epinephrine to bupivacaine does not add a clinically significant length of time to pain relief. Bupivacaine finger blocks provide prolonged hyperemia and pain block to fingertips, which may be useful in the treatment of acute frostbite. Therapeutic, I.

Targinact--opioid pain relief without constipation?

PubMed

2010-12-01

Targinact (Napp Pharmaceuticals Ltd) is a modified-release combination product containing the strong opioid oxycodone plus the opioid antagonist naloxone. It is licensed for "severe pain, which can be adequately managed only with opioid analgesics".1 The summary of product characteristics (SPC) states that "naloxone is added to counteract opioid-induced constipation by blocking the action of oxycodone at opioid receptors locally in the gut". Advertising for the product claims "better pain relief", "superior GI [gastrointestinal] tolerability" and "improved quality of life" "compared to previous treatment in a clinical practice study (n=7836)". Here we consider whether Targinact offers advantages over using strong opioids plus laxatives where required.

The impact of expired and empty quick-relief asthma inhalers: The Asthma and Allergy Foundation of America's Asthma Inhaler Design Survey.

Despite the available treatments, asthma remains a serious illness, with a considerable socioeconomic burden associated with a high number of unscheduled visits to the emergency department (ED). Poor adherence and inadequate inhaler technique are contributing factors to poor asthma management and control. The Asthma Inhaler Design Survey assessed the behaviors, attitudes, needs, and preferences of patients with asthma and their caregivers with regard to quick-relief inhaler usage and device design. The Asthma and Allergy Foundation of America invited 19,157 adult patients and parents of children with asthma to take part in an online survey that focused on previous asthma diagnosis, symptom severity, and quick-relief and controller medication use. Opinions were also collected. Data from 590 respondents (366 adults; 224 children) were included in the final analysis. Relief inhalers were needed and found to be past the expiration date by 284 of 561 (50.6%) and relief inhalers were found to be empty by 270 of 560 (48.2%). Of the empty inhaler group, 28 of 270 (10.4%) had to visit the ED for treatment, 18 of 270 (6.7%) missed work or school for an unscheduled physician office visit, and 54 of 270 (20%) went without treatment. Although 78.5% indicated that they had at least two quick-relief inhalers nearby, these were not always easily accessible. Few respondents (194/578 [33.6%]) indicated that they and/or their child were very confident that they were using their inhaler properly, even though the majority had received some instruction. When asked what they would do to improve satisfaction with their quick-relief inhalers, 173 of 558 (31%) responded that they would add a dose counter. Unnecessary health care utilization and avoidable loss of time at work or school were associated with the lack of full availability of properly functioning quick-relief inhalers when needed. Adding a dose counter was the most frequently cited response for improving satisfaction with quick-relief

Reward, motivation and emotion of pain and its relief

PubMed Central

Porreca, Frank; Navratilova, Edita

2016-01-01

The experience of pain depends on interpretation of context and past experience that guide the choice of an immediate behavioral response and influence future decisions of actions to avoid harm. The aversive qualities of pain underlie its physiological role in learning and motivation. In this review, we highlight findings from human and animal investigations that suggest that both pain, and the relief of pain, are complex emotions that are comprised of feelings and their motivational consequences. Relief of aversive states, including pain, is rewarding. How relief of pain aversiveness occurs is not well understood. Termination of aversive states can directly provide relief as well as reinforce behaviors that result in avoidance of pain. Emerging preclinical data also suggests that relief may elicit a positive hedonic value that results from activation of neural cortical and mesolimbic brain circuits that may also motivate behavior. Brain circuits mediating the reward of pain relief, as well as relief-induced motivation are significantly impacted as pain becomes chronic. In chronic pain states, the negative motivational value of nociception may be increased while the value of the reward of pain relief may decrease. As a consequence, the impact of pain on these ancient, and conserved brain limbic circuits suggest a path forward for discovery of new pain therapies. PMID:28106670

This study assessed which symptoms are most impacted following stellate ganglion block (SGB) used to treat post-traumatic stress disorder (PTSD) symptoms. 30 active military service members with combat-related PTSD self-referred to their physician and psychologist. Patients were offered a SGB as part of their treatment program. Primary outcome was the magnitude of change for the 17 items on the PTSD Checklist-Military (PCL-M), which was administered the week before SGB, 1 week after SGB, and 2 to 4 months later. Mean PCL-M score decreased from 49 at baseline to 32, 1 week after the procedure (p < 0.001). 2 to 4 months after SGB, patients maintained an average PCL-M of 32. Patients reported greatest improvement in the first week after SGB for the following symptoms: irritability or angry outbursts, difficulty concentrating, and sleep disturbance. 2 to 4 months later, patients reported greatest improvement in the following: feeling distant or cut off, feeling emotionally numb, irritability or angry outbursts, and difficulty concentrating. SGB is a safe procedure that may provide extended relief for all clusters of PTSD symptoms. As a result of the significant reduction in hyperarousal and avoidance symptoms observed, this study supports incorporation of SGB into PTSD treatment plans.

A sigh of relief or a sigh to relieve: The psychological and physiological relief effect of deep breaths.

PubMed

Vlemincx, Elke; Van Diest, Ilse; Van den Bergh, Omer

2016-10-15

Both animal and human research have revealed important associations between sighs and relief. Previously we argued to conceive of sighs as resetters which temporarily induce relief. The present study aimed to investigate the psychological and physiological relief effect of sighs by instructed deep breaths and spontaneous sighs compared to a control breathing maneuver. Participants completed three blocks of 40 trials during which uncertainty cues were followed by either safety cues followed by a positive picture, or danger cues followed by a negative picture. One block was presented without breathing instructions, two subsequent blocks with breathing instructions. During the presentation of the safety and danger cues, an instruction was given to either 'take a deep breath' or 'postpone the next inhalation for 2 s (breath hold). Continuously, participants rated relief and Frontalis electromyography was recorded. Trait anxiety sensitivity was assessed by the Anxiety Sensitivity Index. Self-reported relief and physiological tension were compared 5s before and after instructed deep breaths and breath holds, and before and after spontaneous deep breaths and breath holds in the respective blocks. Results show that self-reported relief following an instructed deep breath was higher than before. Physiological tension decreased following a spontaneous sigh in high anxiety sensitive persons and following a spontaneous breath hold in low anxiety sensitive persons. These results are the first to show that a deep breath relieves and, in anxiety sensitive persons, reduces physiological tension. These findings support the hypothesis that sighs are psychological and physiological resetters. Copyright © 2016 Elsevier Inc. All rights reserved.

Background: The nucleus caudalis dorsal root entry zone (DREZ) surgery is used to treat intractable central craniofacial pain. This is the first journal publication of DREZ lesioning used for the long-term relief of an intractable chronic traumatic headache. Case Description: A 40-year-old female experienced new-onset bi-temporal headaches following a traumatic head injury. Despite medical treatment, her pain was severe on over 20 days per month, 3 years after the injury. The patient underwent trigeminal nucleus caudalis DREZ lesioning. Bilateral single-row lesions were made at 1-mm interval between the level of the obex and the C2 dorsal nerve roots, using angled radiofrequency electrodes, brought to 80°C for 15 seconds each, along a path 1 to 1.2 mm posterior to the accessory nerve rootlets. The headache improved, but gradually returned. Five years later, her headaches were severe on over 24 days per month. The DREZ surgery was then repeated. Her headaches improved and the relief has continued for 5 additional years. She has remained functional, with no limitation in instrumental activities of daily living. Conclusions: The nucleus caudalis DREZ surgery brought long-term relief to a patient suffering from chronic traumatic headache. PMID:22059123

2009-12-01

The National Geophysical Data Center (NGDC), an office of the National Oceanic and Atmospheric Administration (NOAA), in conjunction with the Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado at Boulder, has developed a 24 arc-second integrated bathymetric-topographic digital elevation model of Southern Alaska. This Coastal Relief Model (CRM) was generated from diverse digital datasets that were obtained from NGDC, the United States Geological Survey, and other U.S. and international agencies. The CRM spans 170° to 230° E and 48.5° to 66.5° N, including the Gulf of Alaska, Bering Sea, Aleutian Islands, and Alaska’s largest communities: Anchorage, Fairbanks, and Juneau. The CRM provides a framework for enabling scientists to refine tsunami propagation and ocean circulation modeling through increased resolution of geomorphologic features. It may also be useful for benthic habitat research, weather forecasting, and environmental stewardship. Shaded-relief image of the Southern Alaska Coastal Relief Model.

22 countries: tax relief for vaccines, ORS, and contraceptives.

PubMed

Krasovec, K; Connor, C

1999-01-01

This article presents the implementation of tax relief of the three key public health commodities--vaccines, oral rehydration salts (ORS), and contraceptives--in 22 countries. Tax relief was provided in the form of exemptions, waivers, reductions or some combination thereof, with the goal of improving the health status of the population. Tax relief is known to aid in the achievement of policy objectives, which include reduction of buyer's administrative cost, and budget needs, reduction of consumer prices and increase of product supply. Through a global e-mail survey in 1997, information on vaccine, ORS, and contraceptive tax exemptions was gathered. Results revealed that 68% of the countries granted tax relief. It was observed that 87% of the public sector benefits from tax relief for at least one commodity, 67% of the private nonprofit sector, and 53% of the private for-profit sector. On the other hand, the use of waiver procedures for tax relief greatly differs across countries. It was noted that tax exemptions rather than waiver procedures result in the greatest benefits. This article suggests further expansion of private nonprofit and for-profit sectors with appropriate guarantees of consumer savings, as well as implementation of tax relief.

Flow cytometry enables identification of sporophytic eliciting stress treatments in gametic cells.

Flow cytometry was used to quantify the effect of individual and combined stress treatments on elicitation of androgenesis by analyzing the relative nuclear DNA content of in vitro cultured microspores of Pisum sativum L. Differences in relative nuclear DNA content of microspores within anthers after stress treatments were clearly evident from the flow cytometry profiles, and permitted us to predict whether a combination of stresses were elicitors or enhancers of androgenesis. This is the first report to assess the effect of various stress treatments in a plant species based on relative nuclear DNA content and to use this information to categorize them as 'elicitors' or 'enhancers'. Flow cytometry represents a simple, quick and reliable way to analyze and discriminate the effect of various stress treatments on elicitation of androgenesis. These results form a solid basis for further efforts designed to enhance responses and to extend double haploid technology to other legumes. Copyright © 2011 Elsevier GmbH. All rights reserved.

Digital Shaded-Relief Image of Alaska

Introduction One of the most spectacular physiographic images of the conterminous United States, and the first to have been produced digitally, is that by Thelin and Pike (USGS I-2206, 1991). The image is remarkable for its crispness of detail and for the natural appearance of the artificial land surface. Our goal has been to produce a shaded-relief image of Alaska that has the same look and feel as the Thelin and Pike image. The Alaskan image could have been produced at the same scale as its lower 48 counterpart (1:3,500,000). But by insetting the Aleutian Islands into the Gulf of Alaska, we were able to print the Alaska map at a larger scale (1:2,500,000) and about the same physical size as the Thelin and Pike image. Benefits of the 1:2,500,000 scale are (1) greater resolution of topographic features and (2) ease of reference to the U.S. Geological Survey (USGS) (1987) Alaska Map E and the statewide geologic map (Beikman, 1980), which are both 1:2,500,000 scale. Manually drawn, shaded-relief images of Alaska's land surface have long been available (for example, Department of the Interior, 1909; Raisz, 1948). The topography depicted on these early maps is mainly schematic. Maps showing topographic contours were first available for the entire State in 1953 (USGS, 1:250,000) (J.H. Wittmann, USGS, written commun., 1996). The Alaska Map E was initially released in 1954 in both planimetric (revised in 1973 and 1987) and shaded-relief versions (revised in 1973, 1987, and 1996); topography depicted on the shaded-relief version is based on the 1:250,000-scale USGS topographic maps. Alaska Map E was later modified to include hypsometric tinting by Raven Maps and Images (1989, revised 1993) as copyrighted versions. Other shaded-relief images were produced for The National Geographic Magazine (LaGorce, 1956; 1:3,000,000) or drawn by Harrison (1970; 1:7,500,000) for The National Atlas of the United States. Recently, the State of Alaska digitally produced a shaded-relief image

2013-12-02

The objective of this study was to investigate the effects of depression relief and pain relief on the improvement in daily functioning and quality of life (QOL) for depressed patients receiving a 6-week treatment of fluoxetine. A total of 131 acutely ill inpatients with major depressive disorder (MDD) were enrolled to receive 20mg of fluoxetine daily for 6 weeks. Depression severity, pain severity, daily functioning, and health-related QOL were assessed at baseline and again at week 6. Depression severity, pain severity, and daily functioning were assessed using the 17-item Hamilton Depression Rating Scale, the Short-Form 36 (SF-36) Body Pain Index, and the Work and Social Adjustment Scale. Health-related QOL was assessed by three primary domains of the SF-36, including social functioning, vitality, and general health perceptions. Pearson's correlation and structural equation modeling were used to examine relationships among the study variables. Five models were proposed. In model 1, depression relief alone improved daily functioning and QOL. In model 2, pain relief alone improved daily functioning and QOL. In model 3, depression relief, mediated by pain relief, improved daily functioning and QOL. In model 4, pain relief, mediated by depression relief, improved daily functioning and QOL. In model 5, both depression relief and pain relief improved daily functioning and QOL. One hundred and six patients completed all the measures at baseline and at week 6. Model 5 was the most fitted structural equation model (χ(2) = 8.62, df = 8, p = 0.376, GFI = 0.975, AGFI = 0.935, TLI = 0.992, CFI = 0.996, RMSEA = 0.027). Interventions which relieve depression and pain improve daily functioning and QOL among patients with MDD. The proposed model can provide quantitative estimates of improvement in treating patients with MDD. © 2013 Elsevier Inc. All rights reserved.

Statistical Performance Evaluation Of Soft Seat Pressure Relief Valves

Harris, Stephen P.; Gross, Robert E.

2013-03-26

Risk-based inspection methods enable estimation of the probability of failure on demand for spring-operated pressure relief valves at the United States Department of Energy's Savannah River Site in Aiken, South Carolina. This paper presents a statistical performance evaluation of soft seat spring operated pressure relief valves. These pressure relief valves are typically smaller and of lower cost than hard seat (metal to metal) pressure relief valves and can provide substantial cost savings in fluid service applications (air, gas, liquid, and steam) providing that probability of failure on demand (the probability that the pressure relief valve fails to perform its intendedmore » safety function during a potentially dangerous over pressurization) is at least as good as that for hard seat valves. The research in this paper shows that the proportion of soft seat spring operated pressure relief valves failing is the same or less than that of hard seat valves, and that for failed valves, soft seat valves typically have failure ratios of proof test pressure to set pressure less than that of hard seat valves.« less

Chronic treatment with paeonol improves endothelial function in mice through inhibition of endoplasmic reticulum stress-mediated oxidative stress.

2017-01-01

Endoplasmic reticulum (ER) stress leads to endothelial dysfunction which is commonly associated in the pathogenesis of several cardiovascular diseases. We explored the vascular protective effects of chronic treatment with paeonol (2'-hydroxy-4'-methoxyacetophenone), the major compound from the root bark of Paeonia suffruticosa on ER stress-induced endothelial dysfunction in mice. Male C57BL/6J mice were injected intraperitoneally with ER stress inducer, tunicamycin (1 mg/kg/week) for 2 weeks to induce ER stress. The animals were co-administered with or without paeonol (20 mg/kg/oral gavage), reactive oxygen species (ROS) scavenger, tempol (20 mg/kg/day) or ER stress inhibitor, tauroursodeoxycholic acid (TUDCA, 150 mg/kg/day) respectively. Blood pressure and body weight were monitored weekly and at the end of treatment, the aorta was isolated for isometric force measurement. Protein associated with ER stress (GRP78, ATF6 and p-eIF2α) and oxidative stress (NOX2 and nitrotyrosine) were evaluated using Western blotting. Nitric oxide (NO) bioavailability were determined using total nitrate/nitrite assay and western blotting (phosphorylation of eNOS protein). ROS production was assessed by en face dihydroethidium staining and lucigenin-enhanced chemiluminescence assay, respectively. Our results revealed that mice treated with tunicamycin showed an increased blood pressure, reduction in body weight and impairment of endothelium-dependent relaxations (EDRs) of aorta, which were ameliorated by co-treatment with either paeonol, TUDCA and tempol. Furthermore, paeonol reduced the ROS level in the mouse aorta and improved NO bioavailability in tunicamycin treated mice. These beneficial effects of paeonol observed were comparable to those produced by TUDCA and tempol, suggesting that the actions of paeonol may involve inhibition of ER stress-mediated oxidative stress pathway. Taken together, the present results suggest that chronic treatment with paeonol preserved endothelial

Formation of the Ni3Nb δ-Phase in Stress-Relieved Inconel 625 Produced via Laser Powder-Bed Fusion Additive Manufacturing

The microstructural evolution of laser powder-bed additively manufactured Inconel 625 during a post-build stress-relief anneal of 1 hour at 1143 K (870 °C) is investigated. It is found that this industry-recommended heat treatment promotes the formation of a significant fraction of the orthorhombic D0a Ni3Nb δ-phase. This phase is known to have a deleterious influence on fracture toughness, ductility, and other mechanical properties in conventional, wrought Inconel 625; and is generally considered detrimental to materials' performance in service. The δ-phase platelets are found to precipitate within the inter-dendritic regions of the as-built solidification microstructure. These regions are enriched in solute elements, particularly Nb and Mo, due to the micro-segregation that occurs during solidification. The precipitation of δ-phase at 1073 K (800 °C) is found to require up to 4 hours. This indicates a potential alternative stress-relief processing window that mitigates δ-phase formation in this alloy. Ultimately, a homogenization heat treatment is recommended for additively manufactured Inconel 625 because the increased susceptibility to δ-phase precipitation increases the possibility for significant degradation of materials' properties in service.

Hurricanes, floods, tornados, and earthquakes are natural disasters that can happen at any time destroying homes, businesses, and natural surroundings. One such disaster, Hurricane Andrew, devastated South Florida leaving several hundred-thousand people homeless. Many people were without electrical service, functioning water and sewage systems, communications, and medical services for days, even weeks in the aftermath of the storm. Emergency management teams, the military, and countless public and private organizations staged a massive relief effort. Dependency on electrical utility power became a pronounced problem as emergency services were rendered to survivors and the rebuilding process started. Many of the energy needsmore » of emergency management organizations, relief workers, and the general public can be satisfied with solar electric energy systems. Photovoltaic (PV) power generated from solar energy is quiet, safe, inexhaustible and pollution-free. Previously, photovoltaics have supplied emergency power for Hurricanes Hugo and Andrew, and the earthquake at Northridge in Southern California. This document focuses on photovoltaic technology and its application to disaster relief efforts.« less

Treatments for Chronic Pain in Persons With Spinal Cord Injury: A Survey Study

PubMed Central

Cardenas, Diana D; Jensen, Mark P

2006-01-01

Background/Objective: To determine the degree and duration of pain relief provided by specific pain treatments used by individuals with spinal cord injury (SCI) who have chronic pain. Design: Postal survey. Setting: Community. Participants: Participants were 117 individuals who had traumatic SCI, were 18 years of age or older, and reported a chronic pain problem. Main Outcome Measures: Questions assessing current or past use of 26 different pain treatments, the amount of relief each treatment provided, and the length of time that any pain relief usually lasts. Results: The medications tried most often were nonsteroidal anti-inflammatory drugs (tried by 71%) and acetaminophen (tried by 70%); these medications were still being used by more than one half of the patients who had tried them. Opioids produced the greatest degree of pain relief on average (mean, 6.27 ± 3.05 [SD] on a 0–10 scale, with 0 = no relief and 10 = complete relief) but were unlikely to be continued by those who tried them. Although 38% of respondents with pain had tried gabapentin, only 17% were still using it, and average pain relief was only moderate (mean, 3.32 ± 3.03 on the 0–10 relief scale). Seventy-three percent of the respondents had tried at least 1 of 7 alternative pain treatments, and the most frequently tried were massage, marijuana, and acupuncture. The most relief was provided by massage (mean, 6.05 ± 2.47] on the 0–10 relief scale) and marijuana (mean, 6.62 ± 2.54 on the 0–10 relief scale). The relief from the various treatments, including most medications, tended to last only minutes or hours; however, pain relief from alternative treatments such as massage, acupuncture, and hypnosis was reported to last for days in 25% to 33% of those who tried these treatments. Conclusions: Many patients are not finding adequate pain relief from commonly prescribed medications. Alternative therapies should be considered as additional treatment options in this population.

Patients with dementia receive suboptimal palliative care, and this patient group is at risk to have pain at the end of life. Because communicative impairments are common in this patient group, nurses play an important caregiver role in identifying, assessing, and relieving patients' pain. This study aimed to describe nurses' experiences regarding end-of-life pain relief in patients with dementia. This descriptive exploratory qualitative study was based on seven semistructured interviews. Burnard's content analysis inspired the data analysis. Two main categories were identified: (1) nurses' experience of difficulties concerning pain relief and (2) nurses' experience of resources concerning pain relief. Nurses experienced difficulties, such as feeling of powerlessness because of difficulties in obtaining adequate prescriptions for analgesics, ethical dilemmas, feeling of inadequacy because analgesia did not have the desired effect, and a feeling of not being able to connect with the patient. Factors, including knowledge about the patient, professional experience, utilization of pain assessment tools, interpersonal relationships, and interprofessional cooperation, served as resources and enabled end-of-life pain relief. The results of this study highlight the complexity of pain relief in patients with dementia at the end of life from a nursing perspective. The inability of patients with dementia to verbally communicate their pain makes them a vulnerable patient group, dependent on their caregivers. Knowing the life story of the patient, professional experience, teamwork based on good communication, and use of a pain assessment tool were reported by the nurses to improve pain relief at the end of life for patients with dementia.

Neuroinflammatory genes associated with post-traumatic stress disorder: implications for comorbidity.

PubMed

2017-02-01

Post-traumatic stress disorder (PTSD) is a debilitating condition that only occurs in the aftermath of traumatic event exposure and is characterized by an impaired stress response and chronic, low-grade inflammation. Dysregulation of the immune system may contribute towards central nervous system tissue damage and exacerbation of fear memories following trauma. Patients with PTSD often have comorbid psychiatric and somatic disorders that are of themselves associated with heightened inflammation. Several immune-related genes have been associated with PTSD and other co-occurring disorders. In this review, we propose that chronic inflammation, particularly neuroinflammation, is an important contributory factor towards PTSD comorbidity. Thus, novel treatments that target dysregulated inflammatory processes could provide symptomatic relief from PTSD and its comorbid disorders. This review investigates the intricate links between chronic stress, anxiety and neuroinflammation and the potential impact of increased neuroinflammation on PTSD pathology and comorbidity.

Callous-unemotional traits and early life stress predict treatment effects on stress and sex hormone functioning in incarcerated male adolescents.

PubMed

Johnson, Megan; Vitacco, Michael J; Shirtcliff, Elizabeth A

2018-03-01

The stress response system is highly plastic, and hormone rhythms may "adaptively calibrate" in response to treatment. This investigation assessed whether stress and sex hormone diurnal rhythms changed over the course of behavioral treatment, and whether callous-unemotional (CU) traits and history of early adversity affected treatment results on diurnal hormone functioning in a sample of 28 incarcerated adolescent males. It was hypothesized that the treatment would have beneficial effects, such that healthier diurnal rhythms would emerge post-treatment. Diurnal cortisol, testosterone, and dehydroepiandrosterone (DHEA) were sampled two weeks after admission to the correctional/treatment facility, and again approximately four months later. Positive treatment effects were detected for the whole sample, such that testosterone dampened across treatment. CU traits predicted a non-optimal hormone response to treatment, potentially indicating biological preparedness to respond to acts of social dominance and aggression. The interaction between CU traits and adversity predicted a promising and sensitized response to treatment including increased cortisol and a steeper testosterone drop across treatment. Results suggest that stress and sex hormones are highly receptive to treatment during this window of development.

Relief of BPO or improvement in quality of life?

PubMed

Teillac, P

1998-01-01

Benign prostatic hyperplasia (BPH) can cause benign prostatic enlargement with subsequent benign prostatic obstruction (BPO) and lower urinary tract symptoms (LUTS). A reduction in the size of the prostate has long been considered one of the most important treatment goals. However, there is a poor correlation between prostate size and both LUTS and BPO, and between BPO and symptoms. Today, the urologist's primary objectives are to minimize symptoms, relieve BPO and decrease the morbidity associated with BPO. From the patient's point of view, rapid relief of LUTS and immediate improvement in associated quality of life (QOL) are the most important factors. Although there is a good correlation between relief of symptoms (as measured by the International Prostate Symptom Score [I-PSS], for example) and associated improvement in bothersomeness and QOL, particularly that associated with filling ('irritative') symptoms, it is still important to quantify LUTS-related bothersomeness and QOL. Various questionnaires have been developed to measure bothersomeness (e.g. Symptom Problem Index [SPI], Danish PSS [DAN-PSS], International Continence Society BPH Study Group [ICSmale] questionnaire) and QOL (e.g. I-PSS-QOL, BPH Impact Index [BII] and QOL9 BPH-specific questionnaire). In addition, the impact of treatment on sexual function should also be taken into account when judging the overall well being or QOL of the patient. A grading system to evaluate the global improvement in patients following treatment has been established. Patients are either graded as showing 'slight', 'moderate' or 'marked' improvement, with the reduction in I-PSS or BII scores required for each classification dependent on baseline symptom severity. Medical treatment strategies designed to alleviate the symptoms of BPH and consequently improve the patient's QOL are now becoming increasingly important.

Regulatory interactions of stress and reward on rat forebrain opioidergic and GABAergic circuitry.

PubMed

Christiansen, A M; Herman, J P; Ulrich-Lai, Y M

Palatable food intake reduces stress responses, suggesting that individuals may consume such ?comfort? food as self-medication for stress relief. The mechanism by which palatable foods provide stress relief is not known, but likely lies at the intersection of forebrain reward and stress regulatory circuits. Forebrain opioidergic and gamma-aminobutyric acid ergic signaling is critical for both reward and stress regulation, suggesting that these systems are prime candidates for mediating stress relief by palatable foods. Thus, the present study (1) determines how palatable ?comfort? food alters stress-induced changes in the mRNA expression of inhibitory neurotransmitters in reward and stress neurocircuitry and (2) identifies candidate brain regions that may underlie comfort food-mediated stress reduction. We used a model of palatable ?snacking? in combination with a model of chronic variable stress followed by in situ hybridization to determine forebrain levels of pro-opioid and glutamic acid decarboxylase (GAD) mRNA. The data identify regions within the extended amygdala, striatum, and hypothalamus as potential regions for mediating hypothalamic-pituitary-adrenal axis buffering following palatable snacking. Specifically, palatable snacking alone decreased pro-enkephalin-A (ENK) mRNA expression in the anterior bed nucleus of the stria terminalis (BST) and the nucleus accumbens, and decreased GAD65 mRNA in the posterior BST. Chronic stress alone increased ENK mRNA in the hypothalamus, nucleus accumbens, amygdala, and hippocampus; increased dynorphin mRNA in the nucleus accumbens; increased GAD65 mRNA in the anterior hypothalamus and BST; and decreased GAD65 mRNA in the dorsal hypothalamus. Importantly, palatable food intake prevented stress-induced gene expression changes in subregions of the hypothalamus, BST, and nucleus accumbens. Overall, these data suggest that complex interactions exist between brain reward and stress pathways and that palatable snacking can

To evaluate whether an individualized cyclic pressure-relief protocol accelerates wound healing in wheelchair users with established pressure ulcers (PrUs). Randomized controlled study. Spinal cord injury clinics. Forty-four subjects, aged 18-79 years, with a Stage II or Stage III PrU, were randomly assigned to the control (n = 22) or treatment (n = 22) groups. Subjects in the treatment group used wheelchairs equipped with an individually adjusted automated seat that provided cyclic pressure relief, and those in the control group used a standard wheelchair. All subjects sat in wheelchairs for a minimum of 4 hours per day for 30 days during their PrU treatment. Wound characteristics were assessed using the Pressure Ulcer Scale for Healing (PUSH) tool and wound dimensions recorded with digital photographs twice a week. Median healing time for a 30% healing relative to initial measurements, the percentage reduction in wound area, and the percentage improvement in PUSH score achieved at the end of the trial were compared between groups. At the end of 30 days, both groups demonstrated a general trend of healing. However, the treatment group was found to take significantly less time to achieve 30% healing for the wound measurement compared with the control group. The percentage improvement of the wound area and PUSH scores were greater in using cyclic seating (45.0 +/- 21.0, P < .003; 29.9 +/- 24. 6, P < .003) compared with standard seating (10.2 +/- 34.9, 5.8 +/- 9.2). The authors' findings show that cyclically relieving pressure in the area of a wound for seated individuals can greatly aid wound healing. The current study provides evidence that the individualized cyclic pressure-relief protocol helps promote pressure wound healing in a clinical setting. The authors concluded that the individualized cyclic pressure relief may have substantial benefits in accelerating the healing process in wheelchair users with existing PrUs, while maintaining the mobility of

An experimental approach have been proposed to evaluate growth of stress during high temperature oxidation of pure zirconium. The development of stress in the oxide scale has been investigated experimentally in in-situ conditions by combining the Deflection Test in Monofacial Oxidation (DTMO) with Acoustic Emission analysis (AE). Microstructure of the sample were studied by using Scanning Electron Microscopy technique. Oxidation experiments were performed continuously during 24 h at 400 °C and 500 °C in air under normal atmospheric pressure. Taking into account purely elastic behaviour of the material, primary evolution of growth stress developed in the oxide scale during oxidation process have been estimated. Presented study of the Zr/ZrO2 system revealed two opposite phenomena of stress relief when cooling from 400 °C and 500 °C to room temperature. This study is presented as a tool to understand the phenomena of stress evolution in the zirconia layer during isothermal treatment at high temperature and after cooling.

Alterations in nitrogen metabolites after putrescine treatment in alfalfa under drought stress.

Alfalfa (Medicago sativa, Siwa 1) seeds were subjected to drought stress during germination by using polyethylene glycol (PEG 4000) for studying the changes in some enzyme activities involved in nitrogen metabolism and the content of nitrogenous compounds during the first four days of growth after putrescine (Put) treatment. Decreasing the external water potential reduced activities of glutamate-pyruvate transferase (GPT), glutamate-oxaloacetate transferase (GOT) and RNase. Some free amino acids such as proline and glycine increased, while alanine and aspartic acid decreased. Nucleic acids content also decreased. Polyamines e.g., spermidine (Spd) and spermine (Spm) increased at the water potential -0.4 MPa. Put treatment increased activities of GOT, GPT and RNase. Furthermore, Put treatment increased nucleic acids content and the endogenous polyamines under drought stress. Drought stress was imposed during seedling stage by decreasing soil moisture content. GOT, GPT and RNase activities increased in leaves of alfalfa seedlings under drought stress. Soluble nitrogenous compounds accumulated under drought stress, while nucleic acids content decreased. Except glutamic acid, all free amino acids detected increased under drought stress. Put treatment decreased activities of GOT, GPT and RNase, as well as reduced the accumulation of the total soluble nitrogenous compounds, but increased DNA, RNA and protein contents.

Dysphagia is the main symptom of cancer of the esophagus and gastroesophageal junction and causing nutritional problems and weight loss, often counteracted by insertion of self-expandable metal stents or nutrition via an enteral route. Clinical observations indicate that neoadjuvant therapy may effectively and promptly alleviate dysphagia, making such nutrition supportive interventions redundant before surgical resection. The objective of the current study was to carefully study the effects of induction neoadjuvant therapy on dysphagia and its subsequent course and thereby investigate the actual need for alimentary gateways for nutritional support. Thirty-five consecutive patients scheduled for neoadjuvant therapy were recruited and assessed regarding dysphagia and appetite at baseline, after the first cycle of preoperative treatment with either chemotherapy alone or with chemoradiotherapy and before surgery. Platinum-based therapy in combination with 5-fluorouracil was administered intravenously days 1-5 every 3 weeks and consisted of three treatments. Patients receiving combined chemoradiotherapy started radiotherapy on day one of second chemotherapy cycle. They received fractions of 2 Gy/day each up to a total dose of 40 Gy. Watson and Ogilvie dysphagia scores were used to assess dysphagia, while appetite was assessed by the Edmonton Assessment System Visual analogue scale-appetite questionnaire. Patients were evaluated at regular outpatient clinic visits or by telephone. The histological tumor response in the surgical specimen was assessed using the Chirieac scale. Ten patients scheduled for neoadjuvant chemotherapy and 25 patients scheduled for chemoradiotherapy were included in the analysis. There was a significant improvement in dysphagia in both treatment groups, according to both scales, already from baseline to the completion of the first chemotherapy cycle which remained to the end of the neoadjuvant treatment (P < 0.001). Appetite also improved

Stress urinary incontinence is one of the most common gynecological complains. The frequency of its occurrence is from 12 to 25 and even 60%. It is most often observed in patients after menopause, but in a few percent is also found in twenty and thirty years old women. During several years of searching the effective methods of stress urinary incontinence treatment, many operative techniques have been worked out, but none of them became a perfect one. The operation with the use of TVT tape is one of the newest methods of the stress urinary incontinence treatment. The aim of our study was the attempt of the estimation the TVT operation effectiveness in the treatment of stress urinary incontinence in women treated in Surgical Gynecology Department of Polish Mother Health Centre Research Institute in years 2000-2002. Performed analysis of 60 patients at the age between 38 and 76 years revealed that stress urinary incontinence symptoms regressed after TVT operation, as evaluated 7 days after the procedure. In 51.7% of patients anterior colpoplasty or colpoperineoplasty was performed simultaneously to TVT operation. Control studies were performed a month and six months after the operation. Recurrence of the symptoms was observed in 11.7% of the patients. Revealed data let us show that the efficacy of this procedure is very high and reaches 88.3%.

Stress-Related Immune Markers in Depression: Implications for Treatment

PubMed Central

Hughes, Martina M.; Connor, Thomas J.

2016-01-01

Major depression is a serious psychiatric disorder; however, the precise biological basis of depression still remains elusive. A large body of evidence implicates a dysregulated endocrine and inflammatory response system in the pathogenesis of depression. Despite this, given the heterogeneity of depression, not all depressed patients exhibit dysregulation of the inflammatory and endocrine systems. Evidence suggests that inflammation is associated with depression in certain subgroups of patients and that those who have experienced stressful life events such as childhood trauma or bereavement may be at greater risk of developing depression. Consequently, prolonged exposure to stress is thought to be a key trigger for the onset of a depressive episode. This review assesses the relationship between stress and the immune system, with a particular interest in the mechanisms by which stress impacts immune function, and how altered immune functioning, in turn, may lead to a feed forward cascade of multiple systems dysregulation and the subsequent manifestation of depressive symptomology. The identification of stress-related immune markers and potential avenues for advances in therapeutic intervention is vital. Changes in specific biological markers may be used to characterize or differentiate depressive subtypes or specific symptoms and may predict treatment response, in turn facilitating a more effective, targeted, and fast-acting approach to treatment.

Reports of "satisfactory relief" by IBS patients receiving usual medical care are confounded by baseline symptom severity and do not accurately reflect symptom improvement.

Treatment trials for irritable bowel syndrome (IBS) usually define a responder as a patient who reports satisfactory relief or adequate relief of symptoms at the end of the trial. However, these measures have not been adequately validated. (1) Compare a binary satisfactory relief measure to alternative ways of defining a treatment responder. (2) Determine whether baseline IBS symptom severity or psychological distress influence the sensitivity of these outcome measures. A total of 350 patients (81% females, average age 50 yr) who had a medical diagnosis of IBS and satisfied Rome II criteria, were recruited from Group Health Cooperative of Puget Sound. At baseline the Irritable Bowel Severity Scale (IBSS) was used to assess symptom severity and to classify patients as mild, moderate, or severe. Psychological distress and IBS-specific quality of life (IBS-QOL) were also assessed. After 6 months treatment with standard medical care, IBSS and IBS-QOL were reassessed, and patients were asked whether they had experienced satisfactory relief and whether they were somewhat or markedly better. Initial severity of IBS significantly affected the proportion who reported satisfactory relief (mild, 72%; moderate, 53%; severe, 44%) and the proportion who were somewhat or markedly better (mild, 62%; moderate, 44%; severe, 38%), but did not affect the proportion with a 50% reduction in symptoms (mild, 26%; moderate, 25%; severe, 23%). Although mild patients were the most likely to report satisfactory relief, they showed no average decrease in symptom severity or improvement in IBS-QOL. Conversely, severe patients, who were the least likely to report satisfactory relief, had the largest reductions in IBS symptom severity and the largest improvements in IBS-QOL. Psychological distress had no significant effect on the responder rate after adjusting for IBS symptom severity. These data from a descriptive study suggest that satisfactory relief is confounded with initial IBS symptom

Limits on relief through constrained exchange on random graphs

NASA Astrophysics Data System (ADS)

LaViolette, Randall A.; Ellebracht, Lory A.; Gieseler, Charles J.

2007-09-01

Agents are represented by nodes on a random graph (e.g., “small world”). Each agent is endowed with a zero-mean random value that may be either positive or negative. All agents attempt to find relief, i.e., to reduce the magnitude of that initial value, to zero if possible, through exchanges. The exchange occurs only between the agents that are linked, a constraint that turns out to dominate the results. The exchange process continues until Pareto equilibrium is achieved. Only 40-90% of the agents achieved relief on small-world graphs with mean degree between 2 and 40. Even fewer agents achieved relief on scale-free-like graphs with a truncated power-law degree distribution. The rate at which relief grew with increasing degree was slow, only at most logarithmic for all of the graphs considered; viewed in reverse, the fraction of nodes that achieve relief is resilient to the removal of links.

The control of tonic pain by active relief learning

PubMed Central

Mano, Hiroaki; Lee, Michael; Yoshida, Wako; Kawato, Mitsuo; Robbins, Trevor W

2018-01-01

Tonic pain after injury characterises a behavioural state that prioritises recovery. Although generally suppressing cognition and attention, tonic pain needs to allow effective relief learning to reduce the cause of the pain. Here, we describe a central learning circuit that supports learning of relief and concurrently suppresses the level of ongoing pain. We used computational modelling of behavioural, physiological and neuroimaging data in two experiments in which subjects learned to terminate tonic pain in static and dynamic escape-learning paradigms. In both studies, we show that active relief-seeking involves a reinforcement learning process manifest by error signals observed in the dorsal putamen. Critically, this system uses an uncertainty (‘associability’) signal detected in pregenual anterior cingulate cortex that both controls the relief learning rate, and endogenously and parametrically modulates the level of tonic pain. The results define a self-organising learning circuit that reduces ongoing pain when learning about potential relief. PMID:29482716

To examine social issues in the conduct of cleft and craniofacial care through relief programs in disrupted crisis contexts. Social, health policy, and ethical analyses. At best, craniofacial team care is multidisciplinary, coordinated, and sustained, requiring a long-term relationship between team members, patients, and families. Disasters and societal turmoil interrupt such relationships, causing craniofacial care to become a secondary concern. Providing craniofacial team care in a crisis setting requires rebuilding disrupted coordination and communication. Crisis relief care involves a complex set of expectations and responsibilities and raises issues such as (1) quality assurance, infection control, appropriate standards of care, and follow-up care/continuity; (2) equity of access to services and clinical ethics in the context of war and/or deprivation; (3) training of visitors in the local nation or site; (4) disciplinary composition of teams, interprofessional communication/rivalry, and credentials of clinicians; (5) ownership of the site and local visitor relations; (6) fundraising and marketing strategies; and (7) ethical issues in the doctor-patient relationship. Specific ethical standards for international cleft and craniofacial care delivery also apply to domestic and global crisis relief contexts. Guidance on issues related to professional experience, informed consent, and continuity of care will help care providers address social and ethical issues raised in crisis relief programs. This paper proposes that the Position Paper of the American Cleft Palate-Craniofacial Association (ACPA) on International Treatment Programs should be used as a template to develop and disseminate a set of standards that apply to crisis relief.

PubMed

van Velsen, Valery; van Helmond, Noud; Chapman, Kenneth B

2018-04-01

Chronic neuropathic pain is often refractory to conventional medical treatments and leads to significant disability and socio-economic burden. Dorsal root ganglion (DRG) stimulation has recently emerged as a treatment for persistent neuropathic pain, but creating a strain relief loop at the S1 level has thus far been a challenging technical component of DRG lead placement. We describe a refined technique for strain relief loop formation at the S1 level using a transforaminal approach that we employed in a 45-year-old patient with intractable foot pain. We successfully placed a strain relief loop in the sacral space in a predictable and easily reproducible manner using a transforaminal anchorless approach. The patient experienced a decrease in visual analog pain score (85%), and improvement in function during the trial period, and proceeded with permanent implantation. The described sacral transforaminal strain relief loop formation technique appears to be a more reliable and predictable technique of DRG lead placement in the sacrum than those previously documented. © 2017 World Institute of Pain.

Treatment of occipital neuralgia (ON) can be complex, though many treatment options exist. Cryoablation (CA) is an interventional modality that has been used successfully in chronic neuropathic conditions and is one such option. To study and evaluate the efficacy and safety of cryoablation for treatment of ON. Retrospective evaluation. Academic university-based pain management center. All patients received local anesthetic injections for ON. Patients with greater than or equal to 50% relief and less than 2 week duration of relief were treated with CA. Thirty-eight patients with an average age of 49.6 years were included. Of the 38 patients, 20 were treated for unilateral greater ON, 10 for unilateral greater and lesser ON, and 8 for bilateral greater ON. There were 10 men and 28 women, with an average age of 45.2 years and 51.1 years, respectively. The average relief for all local anesthetic injections was 71.2%, 58.3% for patients who reported 50 - 74% relief (Group 1) and 82.75% for patients who reported greater than 75% relief (Group 2). The average improvement of pain relief with CA was 57.9% with an average duration of 6.1 months overall. Group 1 reported an average of 45.2% relief for an average of 4.1 months with CA. In comparison, Group 2 reported an average of 70.5% relief for 8.1 months. The percentage of relief (P = 0.007) and duration of relief (P = 0.0006) was significantly improved in those reporting at least 75% relief of pain with local anesthetic injections (Group 2 vs Group 1). Though no significance in improvement from CA was found in men, significance was seen in women with at least 75% benefit with local anesthetic injections in terms of duration (P = 0.03) and percentage (P = 0.001) of pain relief with CA. The average pain score prior to CA was 8 (0 - 10 visual analog scale, VAS), this improved to 4.2, improvement of 3.8 following CA at 6 months (P = 0.03). Of the 38 patients, 3 (7.8%) adverse effects were seen. Two patients reported post

The management of patients suffering with chronic testicular and groin pain is very challenging. With increased awareness of men's health, more patients and clinicians are open to talk about this complex problem that affects over 100,000 men/year. The pathogenesis of chronic orchialgia is still not clear, but there are several postulated theories. Treatment options include conservative medical therapy with NSAIDs, antidepressants, anticonvulsants, and narcotics. Surgical options such as targeted microsurgical denervation and microcryoablation can provide permanent durable pain relief. The goal of this article is to review and discuss the management of patients with chronic orchialgia using currently available literature.

In a randomised controlled study, a type of cognitive behavior therapy known as Rational Rehabilitation proved effective in the treatment of patients with chronic mental symptoms. Post-traumatic stress disorder is a serious illness that occurs frequently and can last for many years. Rational Rehabilitation may also be an effective treatment for post-traumatic stress disorder. To investigate, via a pilot study, on the effect of Rational Rehabilitation in patients with post-traumatic stress disorder, whether a randomised controlled study is called for. Nineteen patients with post-traumatic stress disorder, who were awaiting regular treatment, opted to join the study. The effect of Rational Rehabilitation was studied in relation to: symptoms of post-traumatic stress disorder, degree of happiness experienced, autonomy, social support and need for further treatment. results Rational Rehabilitation seems to have a positive effect on all outcome measures, except flashbacks. A controlled study of the effect of Rational Rehabilitation in patients with post-traumatic stress disorder seems justified.

Fibromyalgia (FM) is a syndrome whose primary symptoms include chronic widespread muscle pain and fatigue. The treatment of patients with FM aims to provide symptomatic relief and improvement in physical capacities to perform daily tasks and quality of life. Invasive or non-invasive electric stimulation (ES) is used for pain relief in patients with FM. This systematic review aimed to assess the effects of treatment with ES, combined or not combined with other types of therapy, for pain relief in patients with FM. Systematic review and meta-analysis. Electronic search was conducted on databases (from the inception to April 2016): MEDLINE (accessed by PubMed), EMBASE, Cochrane Central Register of Controlled Trials (Cochrane CENTRAL), and Physiotherapy Evidence Database (PEDro). Two independent reviewers assessed the eligibility of studies based on the inclusion criteria: randomized controlled trials (RCTs) examining the effects of ES combined or not with other types of treatment for pain relief in patients with FM (according to the American College of Rheumatology), regardless of the ES dosages. The primary outcome was pain, assessed by the visual analogue scale (VAS). The secondary outcomes extracted were quality of life, assessed by short form-36 health survey (SF- 36), and fatigue, assessed by VAS. Nine studies were included, with 301 patients. The meta-analysis for pain showed positive effect of ES treatment versus control [-1.24 (95% CI: -2.39 to -0.08; I²: 87%, P = 0.04) n = 8 RCTs]. The sensitivity analysis for pain showed significant results for invasive ES, combined or not with other types of therapy [-0.94 (95% CI, -1.50 to -0.38; I² 0%, P = 0.001) n = 3 RCTs]. No significant improvement was found regarding quality of life [-3.48 (95% CI: -12.58 to 5.62; I²: 0%, P = 0.45), n = 2 RCTs] or fatigue [-0.57 (95% CI, -1.25 to 0.11; I² 34%, P = 0.100; n = 4 RCTs]. This systematic review included a small number of studies and reduced number of participants in

Lutz, T J; Bissert, P T; Homce, G T; Yonkey, J A

2018-03-01

Underground refuge alternatives require an air source to supply breathable air to the occupants. This requires pressure relief valves to prevent unsafe pressures from building up within the refuge alternative. The U.S. Mine Safety and Health Administration (MSHA) mandates that pressure relief valves prevent pressure from exceeding 1.25 kPa (0.18 psi), or as specified by the manufacturer, above mine atmospheric pressure when a fan or compressor is used for the air supply. The U.S. National Institute for Occupational Safety and Health (NIOSH) tested a variety of pressure relief valves using an instrumented test fixture consisting of data acquisition equipment, a centrifugal blower, ductwork and various sensors to determine if the subject pressure relief valves meet the MSHA requirement. Relief pressures and flow characteristics, including opening pressure and flow rate, were measured for five different pressure relief valves under a variety of conditions. The subject pressure relief valves included two off-the-shelf modified check valves, two check valves used in MSHA-approved built-in-place refuge alternatives, and a commercially available valve that was designed for a steel refuge alternative and is currently being used in some built-in-place refuge alternatives. The test results showed relief pressures ranging from 0.20 to 1.53 kPa (0.03 to 0.22 psi) and flow rates up to 19.3 m 3 /min (683 scfm). As tested, some of the pressure relief valves did not meet the 1.25 kPa (0.18 psi) relief specification.

Single fluoxetine treatment before but not after stress prevents stress-induced hippocampal long-term depression and spatial memory retrieval impairment in rats

PubMed Central

Han, Huili; Dai, Chunfang; Dong, Zhifang

2015-01-01

A growing body of evidence has shown that chronic treatment with fluoxetine, a widely prescribed medication for treatment of depression, can affect synaptic plasticity in the adult central nervous system. However, it is not well understood whether acute fluoxetine influences synaptic plasticity, especially on hippocampal CA1 long-term depression (LTD), and if so, whether it subsequently impacts hippocampal-dependent spatial memory. Here, we reported that LTD facilitated by elevated-platform stress in hippocampal slices was completely prevented by fluoxetine administration (10 mg/kg, i.p.) 30 min before stress. The LTD was not, however, significantly inhibited by fluoxetine administration immediately after stress. Similarly, fluoxetine incubation (10 μM) during electrophysiological recordings also displayed no influence on the stress-facilitated LTD. In addition, behavioral results showed that a single fluoxetine treatment 30 min before but not after acute stress fully reversed the impairment of spatial memory retrieval in the Morris water maze paradigm. Taken together, these results suggest that acute fluoxetine treatment only before, but not after stress, can prevent hippocampal CA1 LTD and spatial memory retrieval impairment caused by behavioral stress in adult animals.

Thermoelastic Residual Stresses and Deformations at Laser Treatment

NASA Astrophysics Data System (ADS)

Gusarov, A. V.; Malakhova-Ziablova, I. S.; Pavlov, M. D.

A thermoelastic model implying relaxation of stresses at melting is applied for materials with arbitrary thermoelastic properties and the melting point. The range of Poisson's ratio 0.17 - 0.34 is numerically studied. The residual stresses are independent of the space scale. In narrow remelted zones and beads the maximum longitudinal tensile stress is approximately twice as high as the transverse one. The calculations predict cracking of alumina, even with 1600 oC preheating, plastic deformation or cracking of hard metal alloys H13 and TA6 V, and no destruction of polystyrene and thestrongest grades of quartz glass. The calculation results can be used for predicting the thermomechanical stability of materials at laser treatment.

The purpose of this study was to examine mental health treatment use among Vietnam Veterans with posttraumatic stress disorder and determine whether undergoing major surgery interrupted mental health treatment or increased the risk of psychiatric hospitalization. Using retrospective data from Veterans Health Administration's electronic medical record system, a total of 3320 Vietnam-era surgery patients with preoperative posttraumatic stress disorder were identified and matched 1:4 with non-surgical patients with posttraumatic stress disorder. The receipt of surgery was associated with a decline in overall mental health treatment and posttraumatic stress disorder-specific treatment 1 month following surgery but not during any subsequent month thereafter. Additionally, surgery was not associated with psychiatric admission. © The Author(s) 2014.

Bas-relief generation using adaptive histogram equalization.

PubMed

Sun, Xianfang; Rosin, Paul L; Martin, Ralph R; Langbein, Frank C

2009-01-01

An algorithm is presented to automatically generate bas-reliefs based on adaptive histogram equalization (AHE), starting from an input height field. A mesh model may alternatively be provided, in which case a height field is first created via orthogonal or perspective projection. The height field is regularly gridded and treated as an image, enabling a modified AHE method to be used to generate a bas-relief with a user-chosen height range. We modify the original image-contrast-enhancement AHE method to use gradient weights also to enhance the shape features of the bas-relief. To effectively compress the height field, we limit the height-dependent scaling factors used to compute relative height variations in the output from height variations in the input; this prevents any height differences from having too great effect. Results of AHE over different neighborhood sizes are averaged to preserve information at different scales in the resulting bas-relief. Compared to previous approaches, the proposed algorithm is simple and yet largely preserves original shape features. Experiments show that our results are, in general, comparable to and in some cases better than the best previously published methods.

The U.S. National Institute for Occupational Safety and Health (NIOSH) has been researching refuge alternatives (RAs) since 2007. RAs typically have built-in pressure relief valves (PRVs) to prevent the unit from reaching unsafe pressures. The U.S. Mine Safety and Health Administration requires that these valves vent the chamber at a maximum pressure of 1.25 kPa (0.18 psi, 5.0 in. H2O), or as specified by the manufacturer, above mine atmospheric pressure in the RA. To facilitate PRV testing, an instrumented benchtop test fixture was developed using an off-the-shelf centrifugal blower and ductwork. Relief pressures and flow characteristics were measured for three units: (1) a modified polyvinyl chloride check valve, (2) an off-the-shelf brass/cast-iron butterfly check valve and (3) a commercially available valve that was designed specifically for one manufacturer’s steel prefabricated RAs and had been adapted for use in one mine operator’s built-in-place RA. PRVs used in tent-style RAs were not investigated. The units were tested with different modifications and configurations in order to check compliance with Title 30 Code of Federal Regulations, or 30 CFR, regulations. The commercially available relief valve did not meet the 30 CFR relief pressure specification but may meet the manufacturer’s specification. Alternative valve designs were modified to meet the 30 CFR relief pressure specification, but all valve designs will need further design research to examine survivability in the event of a 103 kPa (15.0 psi) impulse overpressure during a disaster.

The application of specialized rectangular relief transmission gratings to coherent lidar beam scanning is presented. Two types of surface relief transmission grating approaches are studied with an eye toward potential insertion of a constant thickness, diffractive scanner where refractive wedges now exist. The first diffractive approach uses vertically oriented relief structure in the surface of an optical flat; illumination of the diffractive scanner is off-normal in nature. The second grating design case describes rectangular relief structure slanted at a prescribed angle with respect to the surface. In this case, illumination is normal to the diffractive scanner. In both cases, performance predictions for 2.0 micron, circularly polarized light at beam deflection angles of 30 or 45 degrees are presented.

Neural stress reactivity relates to smoking outcomes and differentiates between mindfulness and cognitive-behavioral treatments.

2017-05-01

Stress and negative affect are known contributors to drug use and relapse, and several known treatments for addictions include strategies for managing them. In the current study, we administered a well-established stress provocation during functional magnetic resonance imaging (fMRI) to 23 participants who completed either mindfulness training (MT; N=11) or the American Lung Association's Freedom From Smoking (FFS; N=12), which is a cognitive-behavioral treatment (CBT) for smoking cessation. Across the entire sample, we found that stress reactivity in several brain regions including the amygdala and anterior/mid insula was related to reductions in smoking after treatment, as well as at 3-month post-treatment follow-up. Moreover, conjunction analysis revealed that these same regions also differentiated between treatment groups such that the MT group showed lower stress-reactivity compared to the FFS/CBT group. This suggests that reduction in stress reactivity may be one of the mechanisms that underlie the efficacy of MT in reducing smoking over time. The findings have important implications for our understanding of stress, the neural and psychological mechanisms that underlie mindfulness-based treatments, and for smoking cessation treatments more broadly.

Pressure-Relief Features of Fixed and Autotitrating Continuous Positive Airway Pressure May Impair Their Efficacy: Evaluation with a Respiratory Bench Model

PubMed Central

Zhu, Kaixian; Aouf, Sami; Roisman, Gabriel; Escourrou, Pierre

2016-01-01

Study Objectives: Pressure-relief features are aimed at improving the patient's comfort during continuous positive airway pressure (CPAP) treatment for obstructive sleep apnea. The objective of this study was to determine the effect of these therapy features on fixed CPAP and autotitrating CPAP (APAP) treatment efficacy. Methods: Seven pressure-relief features applied by three CPAP devices were included in our study (Remstar Auto: C-Flex 3, C-Flex+ 3, A-Flex 3, P-Flex; AirSense 10: EPR 3; Prisma 20A: SoftPAP 2 and 3). In fixed CPAP, the devices were subjected to a 10-min bench-simulated obstructive apnea sequence (initial apnea-hypopnea index, AHI = 60/h) with and without pressure-relief features. In APAP, the sequence was lengthened to 4.2 h (initial AHI = 58.6/h). The residual AHI and mean/median pressure were compared with and without pressure-relief features. Results: Compared to conventional CPAP, where pressure was adjusted to be just sufficient to control the simulated obstructive events, C-Flex+ 3, P-Flex, and EPR 3 failed to normalize the breathing flow and did not reduce the AHI. The mean pressures with the three features, respectively, were 1.8, 2.6, and 2.6 cmH2O lower than the conventional CPAP. Compared to conventional APAP, similar levels of control were observed with pressure-relief features, apart from P-Flex where the delivered mean pressure was lower and residual AHI greater. The device-reported mean/median pressures in APAP with A-Flex 3, P-Flex, EPR 3, and SoftPAP 3 were higher than that measured on the bench. Conclusions: Pressure-relief features may attenuate CPAP efficacy if not adjusted for at the time of their introduction. In clinical practice, efficacy can be ensured by increasing the therapeutic pressure delivered by fixed CPAP or by enabling the pressure-relief features prior to initial pressure titration. Device-reported pressures in APAP devices with pressure relief activated may overstate delivered pressures. Citation: Zhu K, Aouf S

A Neurogenetic Dissociation between Punishment-, Reward-, and Relief-Learning in Drosophila

PubMed Central

Yarali, Ayse; Gerber, Bertram

2010-01-01

What is particularly worth remembering about a traumatic experience is what brought it about, and what made it cease. For example, fruit flies avoid an odor which during training had preceded electric shock punishment; on the other hand, if the odor had followed shock during training, it is later on approached as a signal for the relieving end of shock. We provide a neurogenetic analysis of such relief learning. Blocking, using UAS-shibirets1, the output from a particular set of dopaminergic neurons defined by the TH-Gal4 driver partially impaired punishment learning, but left relief learning intact. Thus, with respect to these particular neurons, relief learning differs from punishment learning. Targeting another set of dopaminergic/serotonergic neurons defined by the DDC-Gal4 driver on the other hand affected neither punishment nor relief learning. As for the octopaminergic system, the tbhM18 mutation, compromising octopamine biosynthesis, partially impaired sugar-reward learning, but not relief learning. Thus, with respect to this particular mutation, relief learning, and reward learning are dissociated. Finally, blocking output from the set of octopaminergic/tyraminergic neurons defined by the TDC2-Gal4 driver affected neither reward, nor relief learning. We conclude that regarding the used genetic tools, relief learning is neurogenetically dissociated from both punishment and reward learning. This may be a message relevant also for analyses of relief learning in other experimental systems including man. PMID:21206762

How absent negativity relates to affect and motivation: an integrative relief model

2015-01-01

The present paper concerns the motivational underpinnings and behavioral correlates of the prevention or stopping of negative stimulation – a situation referred to as relief. Relief is of great theoretical and applied interest. Theoretically, it is tied to theories linking affect, emotion, and motivational systems. Importantly, these theories make different predictions regarding the association between relief and motivational systems. Moreover, relief is a prototypical antecedent of counterfactual emotions, which involve specific cognitive processes compared to factual or mere anticipatory emotions. Practically, relief may be an important motivator of addictive and phobic behaviors, self destructive behaviors, and social influence. In the present paper, we will first provide a review of conflicting conceptualizations of relief. We will then present an integrative relief model (IRMO) that aims at resolving existing theoretical conflicts. We then review evidence relevant to distinctive predictions regarding the moderating role of various procedural features of relief situations. We conclude that our integrated model results in a better understanding of existing evidence on the affective and motivational underpinnings of relief, but that further evidence is needed to come to a more comprehensive evaluation of the viability of IRMO.

The present paper concerns the motivational underpinnings and behavioral correlates of the prevention or stopping of negative stimulation - a situation referred to as relief. Relief is of great theoretical and applied interest. Theoretically, it is tied to theories linking affect, emotion, and motivational systems. Importantly, these theories make different predictions regarding the association between relief and motivational systems. Moreover, relief is a prototypical antecedent of counterfactual emotions, which involve specific cognitive processes compared to factual or mere anticipatory emotions. Practically, relief may be an important motivator of addictive and phobic behaviors, self destructive behaviors, and social influence. In the present paper, we will first provide a review of conflicting conceptualizations of relief. We will then present an integrative relief model (IRMO) that aims at resolving existing theoretical conflicts. We then review evidence relevant to distinctive predictions regarding the moderating role of various procedural features of relief situations. We conclude that our integrated model results in a better understanding of existing evidence on the affective and motivational underpinnings of relief, but that further evidence is needed to come to a more comprehensive evaluation of the viability of IRMO.

The Great East Japan Earthquake and in particular, the Fukushima Daiichi Nuclear Power Plant accident, have had a serious psychological impact on not only residents, but also relief workers in Fukushima. Although public employees work in highly stressful situations and play a very important role in long-term relief, their psychiatric features have yet to be clarified. The two aims of this study were to identify the current prevalence rate of depression and post-traumatic stress disorder among public employees working in the disaster area using diagnostic interviews, and to speculate on the psychosocial factors affecting their mental condition. We conducted diagnostic interviews and self-administered questionnaires with 168 public employees working in two coastal towns in Fukushima. Results showed that the current prevalence of depression among public employees is as high as 17.9%, in contrast to the relatively low prevalence of post-traumatic stress disorder (4.8%). Based on the results of self-administered questionnaires and interview contents, frequent exposure to strong complaints or anger from residents and role conflicts were considered the cause of the high prevalence of depression. The present study reveals the serious mental status of public employees working in Fukushima and sheds light on the urgent need to establish an efficient care network to provide adequate psychiatric intervention. © 2016 The Authors.

Quantification of neotectonic stress orientations and magnitudes from field observations in Finnmark, northern Norway

NASA Astrophysics Data System (ADS)

Pascal, Christophe; Roberts, David; Gabrielsen, Roy H.

2005-05-01

Fieldwork was conducted in Finnmark, northern Norway, with the purpose of detecting and measuring stress-relief features, induced by quarrying and road works, and to derive from them valuable information on the shallow-crustal stress orientations and magnitudes. Two kinds of stress-relief features were considered in this study. The first consists of drillhole offsets that were found along blasted road-cuts and which were triggered by the sudden rock unloading following the actual blasting. Vertical axial fractures found in the concave remains of boreholes represent the second kind of stress-relief feature. The axial fractures are tension fractures produced by gas overpressure inside the drillhole when the blast occurs. As such, their strike reflects the orientation of the ambient maximum horizontal stress axis. The borehole offsets show mostly reverse-slip displacements to the E-SE and the axial fractures trend NW-SE on average, in agreement with NW-SE compression induced by North Atlantic ridge-push forces. Mechanical considerations of the slip planes offsetting some of the drillholes lead to the conclusion that the magnitude of the maximum horizontal stress at the surface is in the range ˜0.1-˜1 MPa. This range of magnitudes is 1-2 orders less than the horizontal stress magnitudes measured at the surface in other post-glacial environments (e.g. Canada). It is suggested that this difference is related to the marked decline in stress that followed the tremendous post-glacial burst of earthquake activity that affected Fennoscandia but apparently not the Canadian Shield.

Predictive Nomogram for the Durability of Pain Relief From Gamma Knife Radiation Surgery in the Treatment of Trigeminal Neuralgia

DOE Office of Scientific and Technical Information (OSTI.GOV)

Lucas, John T., E-mail: johnthomas75@gmail.com; Nida, Adrian M.; Isom, Scott

Purpose: To determine factors associated with the durability of stereotactic radiation surgery (SRS) for treatment of trigeminal neuralgia (TN). Methods and Materials: Between 1999 and 2008, 446 of 777 patients with TN underwent SRS and had evaluable follow-up in our electronic medical records and phone interview records. The median follow-up was 21.2 months. The Barrow Neurologic Institute (BNI) pain scale was used to determine pre- and post-SRS pain. Dose-volume anatomical measurements, Burchiel pain subtype, pain quality, prior procedures, and medication usage were included in this retrospective cohort to identify factors impacting the time to BNI 4-5 pain relapse by using Cox proportionalmore » hazard regression. An internet-based nomogram was constructed based on predictive factors of durable relief pre- and posttreatment at 6-month intervals. Results: Rates of freedom from BNI 4-5 failure at 1, 3, and 5 years were 84.5%, 70.4%, and 46.9%, respectively. Pain relief was BNI 1-3 at 1, 3, and 5 years in 86.1%, 74.3%, and 51.3% of type 1 patients; 79.3%, 46.2%, and 29.3% of type 2 patients; and 62.7%, 50.2%, and 25% of atypical facial pain patients. BNI type 1 pain score was achieved at 1, 3, and 5 years in 62.9%, 43.5%, and 22.0% of patients with type 1 pain and in 47.5%, 25.2%, and 9.2% of type 2 patients, respectively. Only 13% of patients with atypical facial pain achieved BNI 1 response; 42% of patients developed post-Gamma Knife radiation surgery (GKRS) trigeminal dysfunction. Multivariate analysis revealed that post-SRS numbness (hazard ratio [HR], 0.47; P<.0001), type 1 (vs type 2) TN (HR, 0.6; P=.02), and improved post-SRS BNI score at 6 months (HR, 0.009; P<.0001) were predictive of a durable pain response. Conclusions: The durability of SRS for TN depends on the presenting Burchiel pain type, the post-SRS BNI score, and the presence of post-SRS facial numbness. The durability of pain relief can be estimated pre- and posttreatment by using

Responder analysis for pain relief and numbers needed to treat in a meta-analysis of etoricoxib osteoarthritis trials: bridging a gap between clinical trials and clinical practice

PubMed Central

2010-01-01

Background: Population mean changes from clinical trials are difficult to apply to individuals in clinical practice. Responder analysis may be better, but needs validating for level of response and treatment duration. Methods: The numbers of patients with pain relief over baseline (⩾15%, ⩾30%, ⩾50%, ⩾70%) at 2, 4, 8 and 12 weeks of treatment were obtained using the WOMAC 100 mm visual analogue pain subscale score for each treatment group in seven randomised placebo-controlled trials of etoricoxib in osteoarthritis lasting ⩾6 weeks. Dropouts were assigned 0% improvement from baseline from then on. The numbers needed to treat (NNTs) were calculated at each level of response and time point. Results: 3554 patients were treated with placebo, etoricoxib 30 mg and 60 mg, celecoxib 200 mg, naproxen 1000 mg or ibuprofen 2400 mg daily. Response rates fell with increasing pain relief: 60–80% experienced minimally important pain relief (⩾15%), 50–60% moderate pain relief (⩾30%), 40–50% substantial pain relief (⩾50%) and 20–30% extensive pain relief (⩾70%). NNTs for etoricoxib, celecoxib and naproxen were stable over 2–12 weeks. Ibuprofen showed lessening of effectiveness with time. Conclusion: Responder rates and NNTs are reproducible for different levels of response over 12 weeks and have relevance for clinical practice at the individual patient level. An average 10 mm improvement in pain equates to almost one in two patients having substantial benefit. PMID:19364730

Review article: pH, healing and symptom relief with rabeprazole treatment in acid-related disorders.

PubMed

Robinson, M

2004-11-01

Control of gastric acid secretion by antisecretory agents has been the cornerstone of therapy in the successful management of all acid-related disorders, including gastro-oesophageal reflux disease (GERD), and duodenal and gastric ulcer. Treatment efficacy has been strongly correlated with degree and duration of acid suppression within the 24-h period and with total duration of therapy. All proton pump inhibitors are highly effective for the healing of ulcers and erosive oesophagitis. All have closely similar mechanisms of action, yet important pharmacological differences exist, which can significantly impact certain aspects of their clinical efficacy. Rabeprazole's rapid activation over a wide pH range may be the explanation for its early onset of effective acid inhibition compared with other proton pump inhibitors such as omeprazole, lansoprazole and pantoprazole. Like rabeprazole, esomeprazole is also a potent inhibitor of gastric acid at steady state, although it is thought that rabeprazole may provide enhanced first-day acid suppression compared with esomeprazole. First-day antisecretory efficacy should produce faster symptom relief, a hypothesis supported by clinical data. Moreover, drugs with pharmacological profiles that include both rapid onset and potent antisecretory effects should help control healthcare costs by reducing the need for otherwise commonly used twice-daily proton pump inhibitor administration.

Relief as a Reward: Hedonic and Neural Responses to Safety from Pain

Leknes, Siri; Lee, Michael; Berna, Chantal; Andersson, Jesper; Tracey, Irene

Relief fits the definition of a reward. Unlike other reward types the pleasantness of relief depends on the violation of a negative expectation, yet this has not been investigated using neuroimaging approaches. We hypothesized that the degree of negative expectation depends on state (dread) and trait (pessimism) sensitivity. Of the brain regions that are involved in mediating pleasure, the nucleus accumbens also signals unexpected reward and positive prediction error. We hypothesized that accumbens activity reflects the level of negative expectation and subsequent pleasant relief. Using fMRI and two purpose-made tasks, we compared hedonic and BOLD responses to relief with responses during an appetitive reward task in 18 healthy volunteers. We expected some similarities in task responses, reflecting common neural substrates implicated across reward types. However, we also hypothesized that relief responses would differ from appetitive rewards in the nucleus accumbens, since only relief pleasantness depends on negative expectations. The results confirmed these hypotheses. Relief and appetitive reward task activity converged in the ventromedial prefrontal cortex, which also correlated with appetitive reward pleasantness ratings. In contrast, dread and pessimism scores correlated with relief but not with appetitive reward hedonics. Moreover, only relief pleasantness covaried with accumbens activation. Importantly, the accumbens signal appeared to specifically reflect individual differences in anticipation of the adverse event (dread, pessimism) but was uncorrelated to appetitive reward hedonics. In conclusion, relief differs from appetitive rewards due to its reliance on negative expectations, the violation of which is reflected in relief-related accumbens activation. PMID:21490964

Reward and relief dimensions of temptation to drink: construct validity and role in predicting differential benefit from acamprosate and naltrexone.

PubMed

Roos, Corey R; Mann, Karl; Witkiewitz, Katie

2017-11-01

Researchers have sought to distinguish between individuals whose alcohol use disorder (AUD) is maintained by drinking to relieve negative affect ('relief drinkers') and those whose AUD is maintained by the rewarding effects of alcohol ('reward drinkers'). As an opioid receptor antagonist, naltrexone may be particularly effective for reward drinkers. Acamprosate, which has been shown to down-regulate the glutamatergic system, may be particularly effective for relief drinkers. This study sought to replicate and extend prior work (PREDICT study; Glöckner-Rist et al. ) by examining dimensions of reward and relief temptation to drink and subtypes of individuals with distinct patterns of reward/relief temptation. We utilized data from two randomized clinical trials for AUD (Project MATCH, n = 1726 and COMBINE study, n = 1383). We also tested whether classes of reward/relief temptation would predict differential response to naltrexone and acamprosate in COMBINE. Results replicated prior work by identifying reward and relief temptation factors, which had excellent reliability and construct validity. Using factor mixture modeling, we identified five distinct classes of reward/relief temptation that replicated across studies. In COMBINE, we found a significant class-by-acamprosate interaction effect. Among those most likely classified in the high relief/moderate reward temptation class, individuals had better drinking outcomes if assigned to acamprosate versus placebo. We did not find a significant class-by-naltrexone interaction effect. Our study questions the orthogonal classification of drinkers into only two types (reward or relief drinkers) and adds to the body of research on moderators of acamprosate, which may inform clinical decision making in the treatment of AUD. © 2016 Society for the Study of Addiction.

Social exclusion, personal control, self-regulation, and stress among substance abuse treatment clients.

PubMed

Cole, Jennifer; Logan, T K; Walker, Robert

2011-01-01

The purpose of this study was to examine the relationship of social exclusion, personal control, and self-regulation to perceived stress among individuals who participated in publicly funded substance abuse treatment. Participants entered treatment between June 2006 and July 2007 and completed a 12-month follow-up survey by telephone (n=787). The results of the OLS regression analysis indicate that individuals with greater social exclusion factors (e.g. greater economic hardship, lower subjective social standing, greater perceived discrimination), lower perceived control of one's life, and lower self-regulation had higher perceived stress. Furthermore, a significant interaction was found suggesting a stress-buffering effect of personal control between subjective social standing and perceived stress. Interestingly, income status was not significantly related to perceived stress, while economic hardship, which assesses participants' inability to meet basic expenses, was significantly associated with perceived stress. Future research should examine how to integrate the AA/NA teaching about powerlessness and its role in recovery with the importance of increased personal control and self-control in decreasing perceived stress. Implications for future research and substance abuse treatment are discussed. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

Eddy current characterization of magnetic treatment of nickel 200

NASA Technical Reports Server (NTRS)

Chern, E. J.

1993-01-01

Eddy current methods have been applied to characterize the effect of magnetic treatments on component service-life extension. Coil impedance measurements were acquired and analyzed on nickel 200 specimens that have been subjected to many mechanical and magnetic engineering processes: annealing, applied strain, magnetic field, shot peening, and magnetic field after peening. Experimental results have demonstrated a functional relationship between coil impedance, resistance and reactance, and specimens subjected to various engineering processes. It has shown that magnetic treatment does induce changes in electromagnetic properties of nickel 200 that then exhibit evidence of stress relief. However, further fundamental studies are necessary for a thorough understanding of the exact mechanism of the magnetic field processing effect on machine-tool service life.

Regulatory interactions of stress and reward on rat forebrain opioidergic and GABAergic circuitry

PubMed Central

Christiansen, A.M.; Herman, J.P.; Ulrich-Lai, Y.M.

2011-01-01

Palatable food intake reduces stress responses, suggesting that individuals may consume such “comfort” food as self-medication for stress relief. The mechanism by which palatable foods provide stress relief is not known, but likely lies at the intersection of forebrain reward and stress regulatory circuits. Forebrain opioidergic and gamma-aminobutyric acid (GABA)ergic signaling is critical for both reward and stress regulation suggesting that these systems are prime candidates for mediating stress relief by palatable foods. Thus, the current study aimed to determine 1) how palatable “comfort” food alters stress induced changes in the mRNA expression of inhibitory neurotransmitters in reward and stress neurocircuitry, and 2) identify candidate brain regions that may underlie comfort food-mediated stress reduction. We used a model of palatable “snacking” in combination with a model of chronic variable stress followed by in situ hybridization to determine forebrain levels of pro-opioid and glutamic acid decarboxylase (GAD) mRNA. The data identify regions within the extended amygdala, striatum, and hypothalamus as potential regions for mediating hypothalamic-pituitary-adrenal axis (HPA)-buffering following palatable snacking. Specifically, palatable snacking alone decreased enkephalin mRNA expression in the anterior bed nucleus of the stria terminalis and the nucleus accumbens, as well as decreasing GAD65 mRNA in the posterior bed nucleus of the stria terminalis. Chronic stress alone increased enkephalin mRNA in the hypothalamus, nucleus accumbens, amygdala, and hippocampus; increased dynorphin mRNA in the nucleus accumbens; increased GAD65 mRNA in the anterior hypothalamus and bed nucleus of the stria terminalis; and decreased GAD65 mRNA in the dorsal hypothalamus. Importantly, palatable food intake prevented stress-induced gene expression changes in subregions of the hypothalamus, bed nucleus of the stria terminalis, and nucleus accumbens. Overall, these

Assessment of surface relief and short cracks under cyclic creep in a type 316LN austenitic stainless steel

NASA Astrophysics Data System (ADS)

Sarkar, Aritra; Nagesha, A.; Parameswaran, P.; Sandhya, R.; Laha, K.

2015-12-01

Formation of surface relief and short cracks under cyclic creep (stress-controlled fatigue) in type 316LN stainless steel was studied at temperatures ranging from ambient to 923 K using scanning electron microscopy technique. The surface topography and crack distribution behaviour under cyclic creep were found to be strong functions of testing temperature due to the difference in strain accumulation. At 823 K, surface relief mainly consisted of fine slip markings due to negligible accumulation of strain as a consequence of dynamic strain ageing (DSA) which led to an increase in the cyclic life. Persistent slip markings (PSM) with distinct extrusions containing minute cracks were seen to prevail in the temperature range 873-923 K, indicating a higher slip activity causing higher strain accumulation in the absence of DSA. Besides, a large number of secondary cracks (both transgranular and intergranular) which were partially accentuated by severe oxidation, were observed. Extensive cavitation-induced grain boundary cracking took place at 923 K, which coalesced with PSM-induced transgranular cracks resulting in failure dominated by creep that in turn led to a drastic reduction in cyclic life. Investigations on the influence of stress rate were also carried out which underlined the presence of DSA at 823 K. At 923 K, lowering the stress rate caused further strengthening of the contribution from creep damage marked by a shift in the damage mechanism from cyclic slip to diffusion.

Kava and valerian in the treatment of stress-induced insomnia.

PubMed

Wheatley, D

2001-09-01

Kava and valerian are herbal remedies, claimed to have anxiolytic and sedative properties respectively, without dependence potential or any appreciable side-effects. In this pilot study, 24 patients suffering from stress-induced insomnia were treated for 6 weeks with kava 120 mg daily. This was followed by 2 weeks off treatment and then, 5 having dropped out, 19 received valerian 600 mg daily for another 6 weeks. Stress was measured in three areas: social, personal and life-events; insomnia in three areas also: time to fall asleep, hours slept and waking mood. Total stress severity was significantly relieved by both compounds (p < 0.01) with no significant differences between them; as was also insomnia (p < 0.01). The proportion of patients with no side-effects was 58% with each drug respectively and the 'commonest' effect was vivid dreams with valerian (16%), followed by dizziness with kava (12% ). These compounds may be useful in the treatment of stress and insomnia but further studies are required to determine their relative roles for such indications. Copyright 2001 John Wiley & Sons, Ltd.

Diagnosis, treatment, and rehabilitation of stress fractures in the lower extremity in runners

PubMed Central

Kahanov, Leamor; Eberman, Lindsey E; Games, Kenneth E; Wasik, Mitch

2015-01-01

Stress fractures account for between 1% and 20% of athletic injuries, with 80% of stress fractures in the lower extremity. Stress fractures of the lower extremity are common injuries among individuals who participate in endurance, high load-bearing activities such as running, military and aerobic exercise and therefore require practitioner expertise in diagnosis and management. Accurate diagnosis for stress fractures is dependent on the anatomical area. Anatomical regions such as the pelvis, sacrum, and metatarsals offer challenges due to difficulty differentiating pathologies with common symptoms. Special tests and treatment regimes, however, are similar among most stress fractures with resolution between 4 weeks to a year. The most difficult aspect of stress fracture treatment entails mitigating internal and external risk factors. Practitioners should address ongoing risk factors to minimize recurrence. PMID:25848327

Masticatory performance alters stress relief effect of gum chewing.

PubMed

Nishigawa, Keisuke; Suzuki, Yoshitaka; Matsuka, Yoshizo

2015-10-01

We evaluated the effects of gum chewing on the response to psychological stress induced by a calculation task and investigated the relationship between this response and masticatory performance. Nineteen healthy adult volunteers without dental problems undertook the Uchida-Kraepelin (UK) test (30 min of reiterating additions of one-digit numbers). Before and immediately after the test, saliva samples were collected from the sublingual area of the participants. Three min after the UK test, the participants were made to chew flavorless gum for 3 min, and the final saliva samples were collected 10 min after the UK test. The experiment was performed without gum chewing on a different day. Masticatory performance was evaluated using color-changing chewing gum. Salivary CgA levels at immediately and 10 min after the UK test were compared with and without gum chewing condition. Two-way repeated measures analysis of variance revealed significant interaction between gum chewing condition and changes in CgA levels during post 10 min UK test period. A significant correlation was found between changes in CgA levels and masticatory performance in all participants. Our results indicate that gum chewing may relieve stress responses; however, high masticatory performance is required to achieve this effect. Copyright © 2015 Japan Prosthodontic Society.

Building relations with women's organisations in relief work.

Gell, F

1997-02-01

An Oxfam Emergency Team arrived in Ingushetia in the Northern Caucasus region of the former Soviet Union in August 1996 to set up a program of shelter, rehabilitation, and relief in response to the large influx of people displaced by conflicts in the neighboring republics of Chechnya and North Ossetia. The team was also tasked with contacting community organizations such as women's groups and developing a relationship with them through joint relief work. The Chechen population was comprised of mainly women, children, and the elderly. The internally displaced population of 100,000 people is now scattered throughout the republic in collective centers and host families. Small committees of women were formed to help identify the most vulnerable residents and to distribute winter clothing. It was found during the relief work that fledgling women's groups are establishing themselves as vehicles for change, increasingly open to work with and learn from international organizations such as Oxfam. The Chechen branch of the Union of North Caucasian Women and the Ingushetian ALMOS played leading roles in peacemaking, human rights observance, and humanitarian relief.

Effect of Applied Stress and Temperature on Residual Stresses Induced by Peening Surface Treatments in Alloy 600

NASA Astrophysics Data System (ADS)

Telang, A.; Gnäupel-Herold, T.; Gill, A.; Vasudevan, V. K.

2018-04-01

In this study, the effects of applied tensile stress and temperature on laser shock peening (LSP) and cavitation shotless peening (CSP)-induced compressive residual stresses were investigated using neutron and x-ray diffraction. Residual stresses on the surface, measured in situ, were lower than the applied stress in LSP- and CSP-treated Alloy 600 samples (2 mm thick). The residual stress averaged over the volume was similar to the applied stress. Compressive residual stresses on the surface and balancing tensile stresses in the interior relax differently due to hardening induced by LSP. Ex situ residual stress measurements, using XRD, show that residual stresses relaxed as the applied stress exceeded the yield strength of the LSP- and CSP-treated Alloy 600. Compressive residual stresses induced by CSP and LSP decreased by 15-25% in magnitude, respectively, on exposure to 250-450 °C for more than 500 h with 10-11% of relaxation occurring in the first few hours. Further, 80% of the compressive residual stresses induced by LSP and CSP treatments in Alloy 600 were retained even after long-term aging at 350 °C for 2400 h.

Stress as a seizure precipitant: Identification, associated factors, and treatment options.

PubMed

McKee, Heather R; Privitera, Michael D

2017-01-01

Stress is a common and important seizure precipitant reported by epilepsy patients. Studies to date have used different methodologies to identify relationships between epilepsy and stress. Several studies have identified anxiety, depression, and childhood trauma as being more common in patients with epilepsy who report stress as a seizure precipitant compared to patients with epilepsy who did not identify stress as a seizure precipitant. In one survey study it was found that a majority of patients with stress-triggered seizures had used some type of stress reduction method on their own and, of those who tried this, an even larger majority felt that these methods improved their seizures. Additionally, small to moderate sized prospective trials, including randomized clinical trials, using general stress reduction methods have shown promise in improving outcomes in patients with epilepsy, but results on seizure frequency have been inconsistent. Based on these studies, we recommend that when clinicians encounter patients who report stress as a seizure precipitant, these patients should be screened for a treatable mood disorder. Furthermore, although seizure reduction with stress reduction methods has not been proven in a randomized controlled trial, other important endpoints like quality of life were improved. Therefore, recommending stress reduction methods to patients with epilepsy appears to be a reasonable low risk adjunctive to standard treatments. The current review highlights the need for future research to help further clarify biological mechanisms of the stress-seizure relationship and emphasizes the need for larger randomized controlled trials to help develop evidence based treatment recommendations for our epilepsy patients.

Stress urinary incontinence is a common problem experienced by many women that can have a significant negative impact on the quality of life of those who suffer from the condition and potentially those friends and family members whose lives and activities may also be limited. A comprehensive search of the literature was performed by ECRI Institute. This search included articles published between January 2005 and December 2015 with an updated abstract search conducted through September 2016. When sufficient evidence existed, the body of evidence for a particular treatment was assigned a strength rating of A (high), B (moderate), or C (low) for support of Strong, Moderate, or Conditional Recommendations. In the absence of sufficient evidence, additional information is provided as Clinical Principles and Expert Opinions. The AUA (American Urological Association) and SUFU (Society of Urodynamics, Female Pelvic Medicine & Urogenital Reconstruction) have formulated an evidence-based guideline focused on the surgical treatment of female stress urinary incontinence in both index and non-index patients. The surgical options for the treatment of stress urinary incontinence continue to evolve; as such, this guideline and the associated algorithm aim to outline the currently available treatment techniques as well as the data associated with each treatment. Indeed, the Panel recognizes that this guideline will require continued literature review and updating as further knowledge regarding current and future options continues to grow.

Comparison of nicotine oral soluble film and nicotine lozenge on efficacy in relief of smoking cue-provoked acute craving after a single dose of treatment in low dependence smokers.

PubMed

Du, Daniel; Nides, Mitchell; Borders, James; Selmani, Alex; Waverczak, William

2014-11-01

Pilot study results suggested that a new form of nicotine oral soluble film relieved smoking cue-provoked acute craving faster than nicotine lozenge or gum. The new nicotine film may provide smokers another choice to relieve acute craving. This study compared the efficacy of the 2.5 mg nicotine oral soluble film to 2 mg nicotine lozenge for acute relief of smoking cue-provoked craving. A randomized, open label, active comparator controlled, parallel group study was conducted with 322 smokers enrolled. After 4 h of abstinence from smoking, eligible subjects were exposed to smoking cues as provocation. Immediately after the post-provocation baseline craving assessment using a 0-100 mm visual analogue scale (VAS), subjects took a randomized single dose of either the 2.5 mg nicotine film or the 2 mg nicotine lozenge. Craving assessments were completed at 50 s, 3 min, 5 min, 7 min, 15 min, 20 min, 25 min and 30 min after drug administration. Both treatments reduced cue-induced craving and had similar maximum effects on craving relief. However, the 2.5 mg nicotine film relieved cue-induced craving to a greater degree than the 2 mg nicotine lozenge at 50 s (mean difference: -4.9, p = 0.014), 3 min (mean difference: -6.7, p = 0.011), and 5 min (mean difference: -5.6, p = 0.049) post-treatment. The study confirmed the results from the pilot study. The 2.5 mg nicotine film relieved cue-provoked craving much quicker than the 2 mg nicotine lozenge while both having similar maximum effects. Nicotine film could be useful to provide quick craving relief for low dependence smokers.

Safety and efficacy of glucagon for the relief of acute esophageal food impaction.

PubMed

Weant, Kyle A; Weant, Mallika P

2012-04-01

The safety and efficacy of i.v. glucagon for the relief of acute esophageal food impaction were evaluated. The medical literature was reviewed to identify published trials and case series on the use of i.v. glucagon for the relief of acute esophageal food impaction. Individual case reports and limited case series were excluded from the analysis. This search yielded two retrospective reviews, three prospective reviews, and one randomized, placebo-controlled trial. Only two of the studies analyzed the effect of glucagon alone. Two studies combined this therapy with benzodiazepines, and the other two combined this therapy with an effervescent product and water. Of the two studies that had a control group, one demonstrated no significant difference in the success rate of dislodgement and one showed a nonsignificantly lower success rate in the treatment group. The majority of reports excluded patients with known esophageal strictures and treated a variety of different food-type impactions, making it difficult to determine if the success of this therapy may be tied to a specific subgroup. Few studies documented the adverse effects of this therapy, the most common being nausea and vomiting. Although limited, the available data do not support the use of glucagon for the relief of acute esophageal food impaction. Based on the available data, the use of i.v. glucagon for the relief of acute esophageal food impaction is not supported by the literature. In addition, glucagon has the potential to cause adverse effects and decrease the likelihood of spontaneous resolution.

The Effects of Cryogenic Treatment on Cutting Tools

Kumar, Satish; Khedkar, Nitin K.; Jagtap, Bhushan; Singh, T. P.

2017-08-01

Enhancing the cutting tool life is important and economic factor to reduce the tooling as well as manufacturing cost. The tool life is improved considerably by 92 % after cryogenic treatment. The cryogenic treatment is a one-time permanent, sub-zero heat treatment that entirely changes cross-section of cutting tool. The cryogenic treatment is carried out with deep freezing of cutting tool materials to enhance physical and mechanical properties. The cryogenic treatment improves mechanical such as hardness, toughness and tribological properties such as wear resistance, coefficient of friction, surface finish, dimensional stability and stress relief. The deep cryogenic treatment is the most beneficial treatment applied on cutting tools. The cryogenic treatment is the most advanced heat treatment and popular to improve performance of the cutting tool. The optimization of cryogenic treatment variables is necessary to improve tool life. This study reviews the effects of cryogenic treatment on microstructure, tribological properties of tool steels and machining applications of cutting tool by investigating the surface and performing the surface characterization test like SEM. The economy of cutting tool can be achieved by deep cryogenic treatment.

Effect of rabeprazole and omeprazole on the onset of gastro-oesophageal reflux disease symptom relief during the first seven days of treatment.

2006-10-01

Gastro-oesophageal reflux disease (GORD) symptoms have a significant impact on patients' well-being. Onset of symptom relief is therefore an important consideration in GORD treatment. The primary objective was to compare the efficacy of rabeprazole (20 mg) and omeprazole (20 mg) regarding onset of heartburn control during the first 7 days of treatment in patients with erosive oesophagitis. Secondary objectives included maintenance of sustained heartburn control, control of other GORD symptoms (e.g. acid regurgitation, epigastric pain, dysphagia), effect on quality of life, patient satisfaction with treatment, and adverse events. In this multicentre, randomized, parallel-group, double-blind, comparative study, performed in Europe and Iceland, patients with endoscopically confirmed erosive oesophagitis were randomized to receive once-daily treatment with rabeprazole 20 mg (n=358) or omeprazole 20 mg (n=359) for 7 days. Symptoms were recorded (scored on a 5-point Likert scale) twice daily by the patients on their diary cards. Median time to reach heartburn control was 1.5 days for both the rabeprazole and omeprazole groups (p<0.43). The results were similar between treatments for other study parameters. Both treatments were well tolerated. Unlike previous studies, no significant differences were found between treatments with rabeprazole (20 mg) and omeprazole (20 mg) in this study. Further studies are needed to evaluate the potential benefit of fast-acting proton-pump inhibitors, such as rabeprazole, with respect to onset of symptom control in erosive GORD.

Gas-blowout control by water injection through relief wells: a theoretical analysis. [Injection of water into the formation through relief wells

Koninklijke/Shell Exploratie en Produktie Laboratorium in The Netherlands suggests bringing a gas blowout under control by injecting water into the formation through relief wells. By avoiding direct contact between relief well and blowout well, this technique reduces the inflow of gas by creating sufficient back pressure in the formation itself. The mechanics of the technique are considered.

Excitation of multiple surface-plasmon-polariton waves using a compound surface-relief grating

Faryad, Muhammad; Lakhtakia, Akhlesh

2012-01-01

The excitation of multiple surface-plasmon-polariton waves, all of the same frequency but different polarization states, phase speeds, spatial profiles and degrees of localization, by a compound surface-relief grating formed by a metal and a rugate filter, both of finite thickness, was studied using the rigorous coupled-wave approach. Each period of the compound surface-relief grating was chosen to have an integral number of periods of two different simple surface-relief gratings. The excitation of different SPP waves was inferred from the absorptance peaks that were independent of the thickness of the rugate filter. The excitation of each SPP wave could be attributed to either a simple surface-relief grating present in the compound surface-relief grating or to the compound surface-relief grating itself. However, the excitation of SPP waves was found to be less efficient with the compound surface-relief grating than with a simple surface-relief grating.

Feedbacks Between Topographic Stress and Drainage Basin Evolution

soils near the valley bottom than near the ridgetop. This gradient in soil thickness is largest, and the thickest soil furthest downslope, if most rock damage is assumed to occur near the surface. Ambient tectonic stress also has a strong effect on hillslopes, with more compressive horizontal stress steepening the soil thickness gradient and displacing the thickest soil farther downslope. Rock damage in the valley bottom scales with valley depth, creating a positive feedback between relief and channel incision. This produces higher relief during transient channel incision, but steady-state relief is insensitive to stress effects because the positive feedback is limited by reduction of the channel slope. However, the fact that valleys are typically deepest in the middle of a drainage basin implies that channel profiles will be more concave if stresses enhance channel incision. Observational tests of these qualitative predictions will help evaluate the significance of suspected feedbacks between topographic stress and landscape evolution.

Disaster relief workers are potentially exposed to severe stressors on the job, resulting in a variety of psychological responses. This study aims to clarify the psychological effects of disaster relief activities on Japan Ground Self-Defense Force (JGSDF) personnel following the 2011 Great East Japan Earthquake. A self-report questionnaire was administered to 606 JGSDF personnel one month after completing the disaster relief mission. Posttraumatic stress responses and general psychological distress were assessed using the Impact of Event Scale-Revised (IES-R) and the K10 scales. Associations between outcome variables and independent variables (age, gender, military rank, length of deployment, and exposure to dead bodies) were measured with univariate analyses and subsequent multiple logistic regression analyses. The mean (± SD) IES-R score was 6.2 (± 8.1), and the mean K10 score was 12.8 (± 4.4). In the univariate analyses, exposure to dead bodies and age were identified as significant factors for IES-R and K10 scores, (p < 0.01). However, the multiple logistic regression analyses did not reveal any significant factors although body handlers' exposure approached significance for IES-R. The subjects reported very low psychological responses despite the severe nature of their disaster relief activities. Several factors may account for the low levels of psychological distress and posttraumatic symptoms observed in this study.

Thermo-mechanical treatment effects on stress relaxation and hydrogen embrittlement of cold-drawn eutectoid steels

NASA Astrophysics Data System (ADS)

Caballero, L.; Atienza, J. M.; Elices, M.

2011-12-01

The effects of the temperature and stretching levels used in the stress-relieving treatment of cold-drawn eutectoid steel wires are evaluated with the aim of improving the stress relaxation behavior and the resistance to hydrogen embrittlement. Five industrial treatments are studied, combining three temperatures (330, 400, and 460 °C) and three stretching levels (38, 50 and 64% of the rupture load). The change of the residual stress produced by the treatments is taken into consideration to account for the results. Surface residual stresses allow us to explain the time to failure in standard hydrogen embrittlement tests.

The stress regulator FKBP51: a novel and promising druggable target for the treatment of persistent pain states across sexes.

It is well established that FKBP51 regulates the stress system by modulating the sensitivity of the glucocorticoid receptor to stress hormones. Recently, we have demonstrated that FKBP51 also drives long-term inflammatory pain states in male mice by modulating glucocorticoid signalling at spinal cord level. Here, we explored the potential of FKBP51 as a new pharmacological target for the treatment of persistent pain across the sexes. First, we demonstrated that FKBP51 regulates long-term pain states of different aetiologies independently of sex. Deletion of FKBP51 reduced the mechanical hypersensitivity seen in joint inflammatory and neuropathic pain states in female and male mice. Furthermore, FKBP51 deletion also reduced the hypersensitivity seen in a translational model of chemotherapy-induced pain. Interestingly, these 3 pain states were associated with changes in glucocorticoid signalling, as indicated by the increased expression, at spinal cord level, of the glucocorticoid receptor isoform associated with glucocorticoid resistance, GRβ, and increased levels of plasma corticosterone. These pain states were also accompanied by an upregulation of interleukin-6 in the spinal cord. Crucially, we were able to pharmacologically reduce the severity of the mechanical hypersensitivity seen in these 3 models of persistent pain with the unique FKBP51 ligand SAFit2. When SAFit2 was combined with a state-of-the-art vesicular phospholipid gel formulation for slow release, a single injection of SAFit2 offered pain relief for at least 7 days. We therefore propose the pharmacological blockade of FKBP51 as a new approach for the treatment of persistent pain across sexes, likely in humans as well as rodents.This is an open access article distributed under the Creative Commons Attribution License 4.0 (CCBY), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.

2012-05-07

Relief surface changes provide interesting possibilities for storing diffractive optical elements on photopolymers and are an important source of information for characterizing and understanding the material behavior. In this paper we use a 3-dimensional model, based on direct parameter measurements, for predicting the relief structures generated on without-coverplate photopolymers. We have analyzed different spatial frequency and recording intensity distributions such as binary and blazed periodic patterns. This model was successfully applied to different photopolymers with different values of monomer diffusion.

Alprazolam treatment immediately after stress exposure interferes with the normal HPA-stress response and increases vulnerability to subsequent stress in an animal model of PTSD.

PubMed

Matar, Michael A; Zohar, Joseph; Kaplan, Zeev; Cohen, Hagit

2009-04-01

In light of clinical reports suggesting that early benzodiazepine administration interferes with long-term recovery from traumatic stress, a prospective animal model for PTSD was employed to assess the short- and long-term effects of a brief course of alprazolam following stress exposure. Animals exposed to stress were treated either 1 h or 7 days later with alprazolam or vehicle for 3-days. Outcome measures included behavior in the elevated plus-maze (EPM) and acoustic startle response (ASR) tests 30 days after initial exposure and freezing behavior upon exposure to a trauma-cue on day 31. One group was repeatedly exposed to the triggering trauma shortly before and after treatment and assessed as above. Circulating corticosterone levels were assessed 4 h after initiation of alprazolam and post-treatment. Pre-set cut-off behavioral criteria classified exposed animals according to their EPM and ASR response-patterns into 'extreme', 'minimal,' or 'partial' behavioral response for analysis of prevalence rates. Immediate alprazolam treatment was effective in alleviating anxiety at day 4. No observable anxiolytic effects remained at day 30. Immediate alprazolam also resulted in significantly greater freezing response to trauma-cue exposure and in extreme responses to double-exposure. Corticosterone levels were significantly suppressed by alprazolam during treatment and rebounded after cessation. A brief course of alprazolam in the immediate aftermath of stress-exposure is associated with less favorable responses to additional stress-exposure later on. Alprazolam was associated with a significant attenuation of the HPA-response, suggesting a possible link between initial HPA-axis response disruption and the subsequent unfavorable outcomes.

An enriched environment reduces the stress level and locomotor activity induced by acute morphine treatment and by saline after chronic morphine treatment in mice.

PubMed

Xu, Jia; Sun, Jinling; Xue, Zhaoxia; Li, Xinwang

2014-06-18

This study investigated the relationships among an enriched environment, stress levels, and drug addiction. Mice were divided randomly into four treatment groups (n=12 each): enriched environment without restraint stress (EN), standard environment without restraint stress (SN), enriched environment with restraint stress (ES), and standard environment with restraint stress (SS). Mice were reared in the respective environment for 45 days. Then, the ES and SS groups were subjected to restraint stress daily (2 h/day) for 14 days, whereas the EN and SN groups were not subjected to restraint stress during this stage. The stress levels of all mice were tested in the elevated plus maze immediately after exposure to restraint stress. After the 2-week stress testing period, mice were administered acute or chronic morphine (5 mg/kg) treatment for 7 days. Then, after a 7-day withdrawal period, the mice were injected with saline (1 ml/kg) or morphine (5 mg/kg) daily for 2 days to observe locomotor activity. The results indicated that the enriched environment reduced the stress and locomotor activity induced by acute morphine administration or saline after chronic morphine treatment. However, the enriched environment did not significantly inhibit locomotor activity induced by morphine challenge. In addition, the stress level did not mediate the effect of the enriched environment on drug-induced locomotor activity after acute or chronic morphine treatment.

Coordination and resource maximization during disaster relief efforts.

Lee, Vernon J; Low, Edwin

2006-01-01

In the aftermath of the Earthquake and Tsunami in Southeast Asia, many relief organizations sent medical aid to affected areas. The aim of this paper is to examine the mix of healthcare workers resulting from an influx of aid to Meulaboh, Indonesia, and how they met local healthcare needs. Data were collected from the registration center for relief organizations in Meulaboh and daily hospital meetings on healthcare needs and available workers. Prior to the Tsunami, there were 14 doctors and 120 nurses in the hospital. By the third week after the Tsunami, there were 21 surgeons performing 10 surgeries daily, and >20 non-surgical doctors in the 90-bed hospital. There were <70 nurses available during the month after the Tsunami, which was insufficient for the needs of the hospital. In the town of Meulaboh, the number of doctors exceeded the number of nurses, while public health workers comprised <5% of the healthcare workers. An initial disaster-coordinating agency, formed by the United Nations (UN) in conjunction with affected countries, should link actively with relief organizations. This will optimize help in meeting local needs, and direct relief to where it is needed most.

Effect of admixed high-density polyethylene (HDPE) spheres on contraction stress and properties of experimental composites.

Ferracane, J L; Ferracane, L L; Braga, R R

2003-07-15

Additives that provide stress relief may be incorporated into dental composites to reduce contraction stress (CS). This study attempted to test the hypothesis that conventional fillers could be replaced by high-density polyethylene (HDPE) spheres in hybrid and nanofill composites to reduce CS, but with minimal effect on mechanical properties. Nanofill and hybrid composites were made from a Bis-GMA/TEGDMA resin having either all silica nanofiller or 75 wt.% strontium glass + 5 wt.% silica and replacing some of the nanofiller or the glass with 0%, 5% (hybrid only), 10% or 20 wt.% HDPE. The surface of the HDPE was either left untreated or had a reactive gas surface treatment (RGST). Contraction stress (CS) was monitored for 10 min in a tensilometer (n = 5) after light curing for 60 s at 390 mW/cm(2). Other specimens (n = 5) were light cured 40 s from two sides in a light-curing unit and aged 1 d in water before testing fracture toughness (K(Ic)), flexure strength (FS), and modulus (E). Results were analyzed by ANOVA with Tukey's multiple comparison test at p < 0.05. There was no difference between composites with RGST and untreated HDPE except for FS-10% HDPE hybrid (RGST higher). An increased level of HDPE reduced contraction stress for both types of composites. Flexure strength, modulus (hybrid only), and fracture toughness were also reduced as the concentration of HDPE increased. SEM showed evidence for HDPE debonding and plastic deformation during fracture of the hybrid composites. In conclusion, the addition of HDPE spheres reduces contraction stress in composites, either through stress relief or a reduction in elastic modulus. Copyright 2003 Wiley Periodicals, Inc.

Objective: To evaluate changes in the levels of patient anxiety, depression, motivation, and stress over the course of smoking cessation treatment. Methods: This cohort study involved patients enrolled in a smoking cessation program in Cuiabá, Brazil. We selected patients who completed the program in six months or less (n = 142). Patient evaluations were conducted at enrollment (evaluation 1 [E1]); after 45 days of treatment with medication and cognitive-behavioral therapy (E2); and at the end of the six-month study period (E3). Patients were evaluated with a standardized questionnaire (to collect sociodemographic data and determine smoking status), as well as with the University of Rhode Island Change Assessment scale, Beck Anxiety Inventory, Beck Depression Inventory, and Lipp Inventory of Stress Symptoms for Adults. The data were analyzed with the nonparametric Wilcoxon test for paired comparisons. To compare treatment success (smoking cessation) with treatment failure, the test for two proportions was used. Results: Among the 142 patients evaluated, there were improvements, in terms of the levels of anxiety, depression, motivation, and stress, between E1 and E2, as well as between E1 and E3. In addition, treatment success correlated significantly with the levels of motivation and anxiety throughout the study period, whereas it correlated significantly with the level of depression only at E2 and E3. Conclusions: We conclude that there are in fact changes in the levels of patient anxiety, depression, motivation, and stress over the course of smoking cessation treatment. Those changes appear to be more pronounced in patients in whom the treatment succeeded. PMID:26578135

Opioid combination has been shown to reduce the need for escalating doses for the treatment of cancer pain. A prospective study was planned to evaluate the addition of tramadol to a stronger opioid for the treatment of severe pain as a result of osteoarthritis, previously uncontrolled by non-opioid analgesics or weak opioids. All subjects received tramadol 200 mg and tizanidine 2 mg. At 2 weeks, tramadol was discontinued for patients still reporting poor pain relief (effectiveness ≤50%), and a stronger opioid was titrated to a morphine equivalent amount (MEA) of 40-60 mg orally. After two additional weeks, patients were then divided into two groups: the Strong Opioid Group (SO) and the Tramadol plus the Strong Opioid Group (TSO). The SO group was allowed to escalate opioid dose for lack of effectiveness; the TSO group received tramadol 150 mg daily, thereafter additional strong opioid titration was allowed. A total of 74 patients were studied: SO (n = 40) and TSOG (n = 34). All patients eventually achieved pain relief quality, with both groups reporting similar Karnofsky Performance Scale effectiveness. The SO group achieved satisfactory pain relief (>50%) at an average daily oral MEA of 120 mg. TSO subjects achieved satisfactory pain relief (>50%) at an average daily oral MEA of 95 mg. The addition of tramadol provided a synergistic effect resulting in a 30-mg decrease in necessary morphine equivalents with fewer opioid-related adverse effects. © 2010 The Authors.

Pruritus occurs in all patients with atopic dermatitis and requires quick relief to reduce disease exacerbation and improve quality of life. Crisaborole ointment is a non-steroidal phosphodiesterase 4 inhibitor for the treatment of mild-to-moderate atopic dermatitis. This post hoc analysis explores crisaborole ointment for early relief of pruritus in patients with mild to moderate atopic dermatitis from 2 phase III studies. Patients received crisaborole or vehicle twice daily for 28 days. Pruritus was graded on a 4-point scale of none (0) to severe (3). Early improvement in pruritus required a score of none (0) or mild (1), with a ≥ 1-grade improvement from baseline on day 6. Significantly more patients experienced early improvement in pruritus with crisaborole than with vehicle (56.6% vs 39.5%; p< 0.001), including at earliest assessment (day 2, 34.3% vs 27.3%; p = 0.013). Crisaborole is a topical treatment option that can rapidly relieve atopic dermatitis-associated pruritus.

Ice thickness and topographic relief in glaciated landscapes of the western USA

NASA Astrophysics Data System (ADS)

Brocklehurst, Simon H.; Whipple, Kelin X.; Foster, David

2008-05-01

The development of relief in glaciated landscapes plays a crucial role in hypotheses relating climate change and tectonic processes. In particular, glaciers can only be responsible for peak uplift if they are capable of generating significant relief in formerly nonglaciated landscapes. Previous work has suggested that relief in glaciated landscapes should scale with the thickness of the ice. Here we summarise a field-based test of this hypothesis in two mountain ranges in the western United States, the Sierra Nevada, California, and the Sangre de Cristo Range, Colorado. These areas exhibit a range of degrees of glacial occupation during the Quaternary, including some drainage basins essentially unoccupied by ice, allowing a detailed exploration of how relief in different parts of a drainage basin evolves in response to glacial modification. We mapped last glacial maximum (LGM) trimlines to estimate the ice thickness at the equilibrium line altitude during the LGM, and determined several metrics of relief for drainage basins across the full spectrum of LGM ice extents. Comparison between measures of relief and ice thickness estimates indicates that relief production in glaciated mountain belts scales with ice thickness and consequently also drainage area. We extended our study to the Bitterroot Range in Idaho/Montana, and the Teton Range in Wyoming, for a more comprehensive understanding of sub-ridgeline relief, or 'missing mass'. This measure of mean relief is surprisingly little affected by either the degree of glacial modification or the total material removed by glaciers, but appears to be influenced by the more active tectonics of the Teton Range. While the effects of glacial modification on the landscape are clear (valley widening, hanging valley formation), the overall change in the relief structure of the mountain ranges studied here is surprisingly modest.

Doubling Your Payoff: Winning Pain Relief Engages Endogenous Pain Inhibition1,2,3

PubMed Central

Kwan, Saskia; Schweinhardt, Petra

2015-01-01

Abstract When in pain, pain relief is much sought after, particularly for individuals with chronic pain. In analogy to augmentation of the hedonic experience (“liking”) of a reward by the motivation to obtain a reward (“wanting”), the seeking of pain relief in a motivated state might increase the experience of pain relief when obtained. We tested this hypothesis in a psychophysical experiment in healthy human subjects, by assessing potential pain-inhibitory effects of pain relief “won” in a wheel of fortune game compared with pain relief without winning, exploiting the fact that the mere chance of winning induces a motivated state. The results show pain-inhibitory effects of pain relief obtained by winning in behaviorally assessed pain perception and ratings of pain intensity. Further, the higher participants scored on the personality trait novelty seeking, the more pain inhibition was induced. These results provide evidence that pain relief, when obtained in a motivated state, engages endogenous pain-inhibitory systems beyond the pain reduction that underlies the relief in the first place. Consequently, such pain relief might be used to improve behavioral pain therapy, inducing a positive, perhaps self-amplifying feedback loop of reduced pain and improved functionality. PMID:26464995

Mindfulness-based treatments for posttraumatic stress disorder: a review of the treatment literature and neurobiological evidence

Boyd, Jenna E.; Lanius, Ruth A.; McKinnon, Margaret C.

2018-01-01

Mindfulness-based treatments for posttraumatic stress disorder (PTSD) have emerged as promising adjunctive or alternative intervention approaches. A scoping review of the literature on PTSD treatment studies, including approaches such as mindfulness-based stress reduction, mindfulness-based cognitive therapy and metta mindfulness, reveals low attrition with medium to large effect sizes. We review the convergence between neurobiological models of PTSD and neuroimaging findings in the mindfulness literature, where mindfulness interventions may target emotional under- and overmodulation, both of which are critical features of PTSD symptomatology. Recent emerging work indicates that mindfulness-based treatments may also be effective in restoring connectivity between large-scale brain networks among individuals with PTSD, including connectivity between the default mode network and the central executive and salience networks. Future directions, including further identification of the neurobiological mechanisms of mindfulness interventions in patients with PTSD and direct comparison of these interventions to first-line treatments for PTSD are discussed.

Mathematical proof establishes identity of hypsometric integral and elevation-relief ratio, two quantitative topographic descriptors developed independently of one another for entirely different purposes. Operationally, values of both measures are in excellent agreement for arbitrarily bounded topographic samples, as well as for low-order fluvial watersheds. By using a point-sampling technique rather than planimetry, elevation-relief ratio (defined as mean elevation minus minimum elevation divided by relief) is calculated manually in about a third of the time required for the hypsometric integral.

Serotonin modulates a depression-like state in Drosophila responsive to lithium treatment

PubMed Central

Ries, Ariane-Saskia; Hermanns, Tim; Poeck, Burkhard; Strauss, Roland

2017-01-01

Major depressive disorder (MDD) affects millions of patients; however, the pathophysiology is poorly understood. Rodent models have been developed using chronic mild stress or unavoidable punishment (learned helplessness) to induce features of depression, like general inactivity and anhedonia. Here we report a three-day vibration-stress protocol for Drosophila that reduces voluntary behavioural activity. As in many MDD patients, lithium-chloride treatment can suppress this depression-like state in flies. The behavioural changes correlate with reduced serotonin (5-HT) release at the mushroom body (MB) and can be relieved by feeding the antidepressant 5-hydroxy-L-tryptophan or sucrose, which results in elevated 5-HT levels in the brain. This relief is mediated by 5-HT-1A receptors in the α-/β-lobes of the MB, whereas 5-HT-1B receptors in the γ-lobes control behavioural inactivity. The central role of serotonin in modulating stress responses in flies and mammals indicates evolutionary conserved pathways that can provide targets for treatment and strategies to induce resilience.

Synapsin Determines Memory Strength after Punishment- and Relief-Learning

PubMed Central

2015-01-01

Adverse life events can induce two kinds of memory with opposite valence, dependent on timing: “negative” memories for stimuli preceding them and “positive” memories for stimuli experienced at the moment of “relief.” Such punishment memory and relief memory are found in insects, rats, and man. For example, fruit flies (Drosophila melanogaster) avoid an odor after odor-shock training (“forward conditioning” of the odor), whereas after shock-odor training (“backward conditioning” of the odor) they approach it. Do these timing-dependent associative processes share molecular determinants? We focus on the role of Synapsin, a conserved presynaptic phosphoprotein regulating the balance between the reserve pool and the readily releasable pool of synaptic vesicles. We find that a lack of Synapsin leaves task-relevant sensory and motor faculties unaffected. In contrast, both punishment memory and relief memory scores are reduced. These defects reflect a true lessening of associative memory strength, as distortions in nonassociative processing (e.g., susceptibility to handling, adaptation, habituation, sensitization), discrimination ability, and changes in the time course of coincidence detection can be ruled out as alternative explanations. Reductions in punishment- and relief-memory strength are also observed upon an RNAi-mediated knock-down of Synapsin, and are rescued both by acutely restoring Synapsin and by locally restoring it in the mushroom bodies of mutant flies. Thus, both punishment memory and relief memory require the Synapsin protein and in this sense share genetic and molecular determinants. We note that corresponding molecular commonalities between punishment memory and relief memory in humans would constrain pharmacological attempts to selectively interfere with excessive associative punishment memories, e.g., after traumatic experiences.

Empirically supported psychological treatments for adult acute stress disorder and posttraumatic stress disorder: a review.

PubMed

Ponniah, Kathryn; Hollon, Steven D

2009-01-01

Acute stress disorder (ASD) predicts the development of posttraumatic stress disorder (PTSD), which in some sufferers can persist for years and lead to significant disability. We carried out a review of randomized controlled trials to give an update on which psychological treatments are empirically supported for these disorders, and used the criteria set out by Chambless and Hollon [1998: J Consult Clin Psychol 66:7-18] to draw conclusions about efficacy, first irrespective of trauma type and second with regard to particular populations. The PsycINFO and PubMed databases were searched electronically to identify suitable articles published up to the end of 2008. Fifty-seven studies satisfied our inclusion criteria. Looking at the literature undifferentiated by trauma type, there was evidence that trauma-focused cognitive behavioral therapy (CBT) and eye movement desensitization and reprocessing (EMDR) are efficacious and specific for PTSD, stress inoculation training, hypnotherapy, interpersonal psychotherapy, and psychodynamic therapy are possibly efficacious for PTSD and trauma-focused CBT is possibly efficacious for ASD. Not one of these treatments has been tested with the full range of trauma groups, though there is evidence that trauma-focused CBT is established in efficacy for assault- and road traffic accident-related PTSD. Trauma-focused CBT and to a lesser extent EMDR (due to fewer studies having been conducted and many having had a mixed trauma sample) are the psychological treatments of choice for PTSD, but further research of these and other therapies with different populations is needed.

Population pharmacokinetic-pharmacodynamic modeling of ketamine-induced pain relief of chronic pain.

Pharmacological treatment of chronic (neuropathic) pain is often disappointing. In order to enhance our insight in the complex interaction between analgesic drug and chronic pain relief, we performed a pharmacokinetic-pharmacodynamic (PK-PD) modeling study on the effect of S(+)-ketamine on pain scores in Complex Regional Pain Syndrome type 1 (CRPS-1) patients. Sixty CRPS-1 patients were randomly allocated to received a 100-h infusion of S(+)-ketamine or placebo. The drug infusion rate was slowly increased from 5 mg/h (per 70 kg) to 20 mg/h based upon the effect/side effect profile. Pain scores and drug blood samples were obtained during the treatment phase and pain scores were further obtained weekly for another 11 weeks. A population PK-PD model was developed to analyze the S(+)-ketamine-pain data. Plasma concentrations of S(+)-ketamine and its metabolite decreased rapidly upon the termination of S(+)-ketamine infusion. The chance for an analgesic effect from ketamine and placebo treatment was 67±10% and 23±9% (population value±SE), respectively. The pain data were well described by the PK-PD model with parameters C(50)=10.5±4.8 ng/ml (95% ci 4.37-21.2 ng/ml) and t½ for onset/offset=10.9±4.0 days (5.3-20.5 days). Long-term S(+)-ketamine treatment is effective in causing pain relief in CRPS-1 patients with analgesia outlasting the treatment period by 50 days. These data suggest that ketamine initiated a cascade of events, including desensitization of excitatory receptor systems in the central nervous system, which persisted but slowly abated when ketamine molecules were no longer present.

Are Stressful Life Events (SLEs) Associated with the Utilization of Substance Use Treatment-Related Services?

Cruz-Feliciano, Miguel A; Ferraro, Aimee; Witt Prehn, Angela

2017-03-01

This study described herein explored the association of stressful life events with the utilization of substance use treatment-related services among substance users living in Puerto Rico. A secondary data analysis was conducted using data collected by a research project entitled Puerto Rico Drug Abuse Research Development Program II (PRDARDP II). The study population consisted of 378 individuals from 18 to 35 years of age who were residents of the San Juan metropolitan area and who presented evidence of substance use in the 30 days prior to the interview. The analysis considered demographic data, information on patterns of substance use, substance use treatment history, stressful events, and depression and anxiety symptomatology. As the number of stressful life events increased, substance users were more likely to report having utilized substance use treatment-related services (OR = 1.11, 95% CI [1.06, 1.17], p < 0.001). Relapsing, the inability to afford drugs, and poor working conditions were statistically significant stressful life events associated with the utilization of substance use treatment-related services. Despite the structural limitations associated with access to and with the quality of the services in the substance use treatment-related system of Puerto Rico, findings suggest that stressful life events play a significant role in the utilization of those services. Researchers and clinicians should consider screening for stressful life events in outreach and engagement strategies. At the same time, the assessment of stressful life events should be integrated into the treatment planning stage to support the recovery process of people with substance use disorders.

Anxiety, stress, depression, and patients' responses to periodontal treatment: periodontists' knowledge and professional behavior.

Anxiety, stress, and depression affect the use of health care services, treatment decision-making, and responses to periodontal treatment. This study explored periodontists' confidence in detecting patient anxiety, stress, or depression, as well as their knowledge concerning the relationships between these factors and patients' pain, use of pain medication, and wound healing after periodontal treatment. In addition, this research surveyed if (and which) special accommodations were offered when treating patients with high levels of anxiety, stress, or depression. Data were collected from 171 members of the American Academy of Periodontology (response rate = 34.41%). Most respondents were male (82.2%), white (88.2%), and practiced in solo practices (60.9%). The respondents were more knowledgeable about the effects of anxiety and stress on pain, the use of pain medication, and wound healing than about the impact of depression on these outcomes. They agreed more strongly with statements that they were more confident in their ability to perceive when patients were anxious and stressed than when they were depressed. They also offered more special accommodations for patients with anxiety and stress than for patients with depression. The respondents were significantly less knowledgeable about the impact of depression on patients' responses to periodontal treatment than about the effect of anxiety and stress. Given the evidence concerning the relationships among depression, pain, pain medication use, and wound healing, it is important to educate periodontists about the role of anxiety and stress and the significance of depression on their patients' responses to periodontal therapy.

Although most anterior tibial stress fractures heal with nonoperative treatment, some may require surgical management. To our knowledge, no systematic review has been conducted regarding surgical treatment strategies for the management of chronic anterior tibial stress fractures from which general conclusions can be drawn regarding optimal treatment in high-performance athletes. This systematic review was conducted to evaluate the surgical outcomes of anterior tibial stress fractures in high-performance athletes. Systematic review; Level of evidence, 4. In February 2017, a systematic review of the PubMed, MEDLINE, Cochrane, SPORTDiscus, and CINAHL databases was performed to identify studies that reported surgical outcomes for anterior tibial stress fractures. Articles meeting the inclusion criteria were screened, and reported outcome measures were documented. A total of 12 studies, published between 1984 and 2015, reporting outcomes for the surgical treatment of anterior tibial stress fractures were included in this review. All studies were retrospective case series. Collectively, surgical outcomes for 115 patients (74 males; 41 females) with 123 fractures were evaluated in this review. The overall mean follow-up was 23.3 months. The most common surgical treatment method reported in the literature was compression plating (n = 52) followed by drilling (n = 33). Symptom resolution was achieved in 108 of 123 surgically treated fractures (87.8%). There were 32 reports of complications, resulting in an overall complication rate of 27.8%. Subsequent tibial fractures were reported in 8 patients (7.0%). Moreover, a total of 17 patients (14.8%) underwent a subsequent procedure after their initial surgery. Following surgical treatment for anterior tibial stress fracture, 94.7% of patients were able to return to sports. The available literature indicates that surgical treatment of anterior tibial stress fractures is associated with a high rate of symptom resolution and return

Nursing Students' Attitudes and Use of Holistic Therapies for Stress Relief.

PubMed

Kinchen, Elizabeth V; Loerzel, Victoria

2018-03-01

The purpose of this study was to explore student nurses' openness to using or recommending holistic therapies, the strategies they use to manage stress from school or work, and their perceptions of the impact of holistic therapies on personal health. Qualitative component of a quasi-experimental, mixed-methods study. A convenience sample of undergraduate nursing students in a southeastern U.S. university completed baseline surveys, including demographics and three open-ended questions regarding attitudes toward holistic therapies and strategies used for stress management. Qualitative thematic analysis was undertaken to identify recurring themes in textual data. Students are open to using or recommending holistic therapies but identify lack of knowledge and lack of time as barriers to their practice. Among strategies used by student nurses to manage stress from school or work were physical activity, prayer and meditation, time management, distraction, socialization, artistic pursuits, animal interactions, and other activities. Themes describing holistic therapies' impact on personal health were wholeness, self-empowerment, relaxation/restoration, and alternative/complement to traditional medicine. Findings indicate receptiveness by student nurses to the use of holistic therapies but point to the need for the inclusion of informational as well as experiential education on holistic therapies within nursing curricula.

Secondary Craters in Bas Relief

NASA's Mars Reconnaissance Orbiter (MRO) captured this region of Mars, sprayed with secondary craters from 10-kilometer Zunil Crater to the northwest. Secondary craters form from rocks ejected at high speed from the primary crater, which then impact the ground at sufficiently high speed to make huge numbers of much smaller craters over a large region. In this scene, however, the secondary crater ejecta has an unusual raised-relief appearance like bas-relief sculpture. How did that happen? One idea is that the region was covered with a layer of fine-grained materials like dust or pyroclastics about 1 to 2 meters thick when the Zunil impact occurred (about a million years ago), and the ejecta served to harden or otherwise protect the fine-grained layer from later erosion by the wind. https://photojournal.jpl.nasa.gov/catalog/PIA21591

Medial tibial stress syndrome: conservative treatment options.

Galbraith, R Michael; Lavallee, Mark E

2009-10-07

Medial tibial stress syndrome (MTSS), commonly known as "shin splints," is a frequent injury of the lower extremity and one of the most common causes of exertional leg pain in athletes (Willems T, Med Sci Sports Exerc 39(2):330-339, 2007; Korkola M, Amendola A, Phys Sportsmed 29(6):35-50, 2001; Hreljac A, Med Sci Sports Exerc 36(5):845-849, 2004). Although often not serious, it can be quite disabling and progress to more serious complications if not treated properly. Often, the cause of MTSS is multi-factorial and involves training errors and various biomechanical abnormalities. Few advances have been made in the treatment of MTSS over the last few decades. Current treatment options are mostly based on expert opinion and clinical experience. The purpose of this article is to review published literature regarding conservative treatment options for MTSS and provide recommendations for sports medicine clinicians for improved treatment and patient outcomes.

Role of stresses in annealing of ion-implantation damage in Si

DOE Office of Scientific and Technical Information (OSTI.GOV)

Seshan, K.; EerNisse, E.P.

Recent results showing a crystallographic orientation dependence of growth kinetics, secondary defects, and stress relief in annealing of ion-implanted Si are shown to be self-consistent if interpreted in terms of the influence of stresses upon annealing processes. The stress influence proposed is microplastic shear which is induced in (112) directions on (111) planes inclined to the implant surface by the biaxial stress created in the implant region by ion-implantation damage. The shear stresses are shown to be dependent on crystallographic orientation in a manner consistent with the model.

Fatigue is a frequent and distressing symptom in children undergoing leukemia treatment; however, little is known about factors influencing this symptom. Antioxidants such as glutathione can decrease symptom severity in adult oncology patients, but no study has evaluated antioxidants' effects on symptoms in pediatric oncology patients. This study describes fatigue patterns and associations of fatigue with antioxidants represented by reduced glutathione (GSH) and the reduced/oxidized glutathione (GSH/GSSG) ratio among children receiving leukemia treatment. A repeated measures design assessed fatigue and antioxidants among 38 children from two large U.S. cancer centers. Fatigue was assessed among school-age children and by parent proxy among young children. Antioxidants (GSH and GSH/GSSG ratio) were assessed from cerebrospinal fluid at four phases during leukemia treatment. Young children had a steady decline of fatigue from the end of induction treatment through the continuation phase of treatment, but no significant changes were noted among the school-age children. Mean antioxidant scores varied slightly over time; however, the GSH/GSSG ratios in these children were significantly lower than the normal ratio. Mean GSH/GSSG ratios significantly correlated to fatigue scores of the school-age children during early phases of treatment. Children with low mean GSH/GSSG ratios demonstrated oxidative stress. The low ratios noted early in therapy were significantly correlated with higher fatigue scores during induction and postinduction treatment phases. This finding suggests that increased oxidative stress during the more intensive phases of therapy may explain the experience of fatigue children report. © The Author(s) 2016.

Researchers found that oxidative stress was closely related to the development of diabetes, and hyperglycemia was a main cause for oxidative stress. Many researchers have proved that oxidative stress, present in diabetes, can aggravate diabetes. Now, traditional Chinese medicines have certain treatment and relief effects for oxidative stress in diabetes, but there are no scientific and systematic conclusions on the efficacy of different Chinese medicines for diabetes and complications. Tomakea scientific and systematic review on the recent years' researches on antioxidation effects of traditional Chinese medication polysaccharides for diabetes, analyze the antioxidation effects of sports in treatment of diabetes, and provide the reference and basis for medications and sports in diabetic patients, as well as prevention and treatments of diabetes and complications from aspects of "internal nursing and external workouts". Databases of CNKI and PubMed were retrieved with key words of "diabetes, oxidative stress, antioxidant, traditional Chinese medication, polysaccharide, sports" in both Chinese and English from Jan 2000 to Apr 2016.Finally 118 papers were included in for analysis and review. Polysaccharides of traditional Chinese medications as well as sports have antioxidation effects for diabetes and its complications, and the combination of these two would produce huge significance for relieving oxidative stress in diabetes, as well as for the prevention and treatment of diabetes and its complications. We need further researches on the levels of oxidative stress markers, doses of Chinese medicines, and the time of taking medications. Copyright© by the Chinese Pharmaceutical Association.

Field test and laboratory analog model test on the stress-relief effects of protective layer extraction are time-consuming and laborious. In this paper, on the basis of full consideration of rock heterogeinity and in combination with gas geology at Pingdingshan Mine 5, a numerical model was estalished with the gas-solid coupling rock failure process analysis system RFPA-Gas to simulate the stress variation law, roof and floor deformation, fracture evolution law, displacement in the protected seam, change in gas permeability and gas migration law during protective layer extraction. The simulation results repoduced stress variations in coal and rock strata, roof and floor deformation and fracture evolution process during protective layer extraction. The movement of rock strata were characterized by upper three zones and lower two zones: caving zone, fracture zone and bending subsidence zone in the vertical direction in the overlying strata; floor deformation and failure zone and elasto-plastic deformation zone in the vertical direction in the underlying strata. It showed that stress relief occurred in the protected seam, which led to vertical and horizontal displacements, significant increase in gas permeability, gas desorption and migration. Hence, the outburst threat in the protected seam was eliminated. Meanwhile, with comprehensive analysis of variaition of stress state, deformation characteristics and fracture distribution in coal seam and with consideration of changes in gas leakage rate, gas pressure and permeability, according to gas leakage rate, the floor strata of the protecive layer were divided into four leakage zones. They corresponded to four zones with different stress states and fracture development: original leakage zone - slow reducing leakage zone - dramatic increasing leakage zone- steady increasing leakage zone. This classification provides a clear direction for gas control in the protective layer. The simulation results are in good agreement

Climatic vs. tectonic control on glacial relief

Prasicek, Günther; Herman, Frederic; Robl, Jörg

2017-04-01

The limiting effect of a climatically-induced glacial buzz-saw on the height of mountain ranges has been extensively discussed in the geosciences. The buzz-saw concept assumes that solely climate controls the amount of topography present above the equilibrium line altitude (ELA), while the rock uplift rate plays no relevant role. This view is supported by analyses of hypsometric patterns in orogens worldwide. Furthermore, numerical landscape evolution models show that glacial erosion modifies the hypsometry and reduces the overall relief of mountain landscapes. However, such models often do not incorporate tectonic uplift and can only simulate glacial erosion over a limited amount of time, typically one or several glacial cycles. Constraints on glacial end-member landscapes from analytical, time-independent models are widely lacking. Here we present a steady-state solution for a glacier equilibrium profile in an active orogen modified from the mathematical conception presented by Headley et al. (2012). Our approach combines a glacial erosion law with the shallow ice approximation, specifically the formulations of ice sliding and deformation velocities and ice flux, to calculate ice surface and bed topography from prescribed specific mass balance and rock uplift rate. This solution allows the application of both linear and non-linear erosion laws and can be iteratively fitted to a predefined gradient of specific mass balance with elevation. We tested the influence of climate (fixed rock uplift rate, different ELAs) and tectonic forcing (fixed ELA, different rock uplift rates) on steady-state relief. Our results show that, similar to fluvial orogens, both climate and rock uplift rate exert a strong influence on glacial relief and that the relation among rock uplift rate and relief is governed by the glacial erosion law. This finding can provide an explanation for the presence of high relief in high latitudes. Headley, R.M., Roe, G., Hallet, B., 2012. Glacier

Rationale A rigorously investigated model of stress and antidepressant administration during pregnancy is needed to evaluate possible effects on the mother. Objective The objective of this study was to develop a model of clinically relevant prenatal exposure to an antidepressant and stress during pregnancy to evaluate the effects on maternal care behavior. Results Female rats implanted with 28 day osmotic minipumps delivering the SSRI escitalopram throughout pregnancy had serum escitalopram concentrations in a clinically observed range (17-65 ng/mL). A separate cohort of pregnant females exposed to a chronic unpredictable mild stress paradigm on gestational days 10-20 showed elevated baseline (305 ng/mL), and acute stress-induced (463 ng/mL), plasma corticosterone concentrations compared to unstressed controls (109 ng/mL). A final cohort of pregnant dams were exposed to saline (control), escitalopram, stress, or stress and escitalopram to determine the effects on maternal care. Maternal behavior was continuously monitored over the first 10 days post parturition. A reduction of 35% in maternal contact and 11% in nursing behavior was observed due to stress during the light cycle. Licking and grooming behavior was unaffected by stress or drug exposure in either the light or dark cycle. Conclusions These data indicate that: 1) clinically relevant antidepressant treatment during human pregnancy can be modeled in rats using escitalopram; 2) chronic mild stress can be delivered in a manner that does not compromise fetal viability; and 3) neither of these prenatal treatments substantially altered maternal care post parturition.

Recent evidence has shown that a single maintenance dose of heroin attenuates psychophysiological stress responses in heroin-dependent patients, probably reflecting the effectiveness of heroin-assisted therapies for the treatment of severe heroin addiction. However, the underlying neural circuitry of these effects has not yet been investigated. Using a cross-over, double-blind, vehicle-controlled design, 22 heroin-dependent and heroin-maintained outpatients from the Centre of Substance Use Disorders at the University Hospital of Psychiatry in Basel were studied after heroin and placebo administration, while 17 healthy controls from the general population were included for placebo administration only. Functional magnetic resonance imaging was used to detect brain responses to fearful faces and dynamic causal modelling was applied to compute fear-induced modulation of connectivity within the emotional face network. Stress responses were assessed by hormone releases and subjective ratings. Relative to placebo, heroin acutely reduced the fear-induced modulation of connectivity from the left fusiform gyrus to the left amygdala and from the right amygdala to the right orbitofrontal cortex in dependent patients. Both of these amygdala-related connectivity strengths were significantly increased in patients after placebo treatment (acute withdrawal) compared to healthy controls, whose connectivity estimates did not differ from those of patients after heroin injection. Moreover, we found positive correlations between the left fusiform gyrus to amygdala connectivity and different stress responses, as well as between the right amygdala to orbitofrontal cortex connectivity and levels of craving. Our findings indicate that the increased amygdala-related connectivity during fearful face processing after the placebo treatment in heroin-dependent patients transiently normalizes after acute heroin maintenance treatment. Furthermore, this study suggests that the assessment of

Stress-Rupture and Stress-Relaxation of SiC/SiC Composites at Intermediate Temperature

Tensile static stress and static strain experiments were performed on woven Sylramic (Dow Corning, Midland, MI) and Hi-Nicalon (Nippon Carbon, Japan) fiber reinforced, BN interphase, melt-infiltrated SiC matrix composites at 815 C. Acoustic emission was used to monitor the damage accumulation during the test. The stress-rupture properties of Sylramic composites were superior to that of Hi-Nicalon Tm composites. Conversely, the applied strain levels that Hi-Nicalon composites can withstand for stress-relaxation experiments were superior to Sylramic composites; however, at a cost of poor retained strength properties for Hi-Nicalon composites. Sylramic composites exhibited much less stress-oxidation induced matrix cracking compared to Hi-Nicalon composites. This was attributed to the greater stiffness and roughness of Sylramic fibers themselves and the lack of a carbon layer between the fiber and the BN interphase for Sylramic composites, which existed in Hi-Nicalon composites. Due to the lack of stress-relief for Sylramic composites, time to failure for Sylramic composite stress-relaxation experiments was not much longer than for stress-rupture experiments when comparing the peak stress condition for stress-relaxation with the applied stress of stress-rupture.

Oxidative stress and dietary phytochemicals: Role in cancer chemoprevention and treatment.

Several epidemiological observations have shown an inverse relation between consumption of plant-based foods, rich in phytochemicals, and incidence of cancer. Phytochemicals, secondary plant metabolites, via their antioxidant property play a key role in cancer chemoprevention by suppressing oxidative stress-induced DNA damage. In addition, they modulate several oxidative stress-mediated signaling pathways through their anti-oxidant effects, and ultimately protect cells from undergoing molecular changes that trigger carcinogenesis. In several instances, however, the pro-oxidant property of these phytochemicals has been observed with respect to cancer treatment. Further, in vitro and in vivo studies show that several phytochemicals potentiate the efficacy of chemotherapeutic agents by exacerbating oxidative stress in cancer cells. Therefore, we reviewed multiple studies investigating the role of dietary phytochemicals such as, curcumin (turmeric), epigallocatechin gallate (EGCG; green tea), resveratrol (grapes), phenethyl isothiocyanate (PEITC), sulforaphane (cruciferous vegetables), hesperidin, quercetin and 2'-hydroxyflavanone (2HF; citrus fruits) in regulating oxidative stress and associated signaling pathways in the context of cancer chemoprevention and treatment.

In two experiments using a decision-making game, we investigated children's thinking about regret and relief. In Experiment 1 (N=43, 31 children [5 years 4 months to 8 years 2 months of age] and 12 adults), participants chose between two boxes containing different numbers of stickers. They rated their happiness before learning that the other box contained more (regret) or fewer (relief) stickers. They rerated their chosen box with the counterfactual knowledge. The experience of regret was evident at 5 years of age, and the experience of relief was evident at 7 years of age. In Experiment 2 (N=69, 53 children [5 years 3 months to 6 years 11 months of age] and 16 adults), participants either played the game (self condition) or watched another play the game (other condition). Children in the self condition confirmed the results from Experiment 1. We found no evidence that children up to 7 years of age were able to predict others' regret and relief, a finding that suggests differing developmental trajectories between experiencing and understanding others' regret and relief.

[Posttraumatic stress disorder endophenotypes: several clinical dimensions for specific treatments].

PubMed

Auxéméry, Y

2012-01-01

Posttraumatic stress disorder is a syndrome with a very complex clinical that it is useful to describe according to a multidimensional approach. Following a critical review of the international literature, we have been able to highlight the genetic supports of posttraumatic stress disorder in the perspective of returning to the source of the clinical of this syndrome in order to steer its treatment better. We consider in succession the neuromodulation pathways involving dopamine, serotonine and noradrenaline to describe the hyperdomaminergic, hyposerotoninergic and hypernoradrenergic endophenotypes of posttraumatic stress disorder. Neurogenetic studies have affirmed two essential proposals. On the one hand, the pharmacological treatment of psychotraumatic disorders can be very closely adjusted to the different endophenotypes. On the other hand, the psychotherapeutic approach retains all its importance in the sense that it is the subjective implication that generated the trauma, subjectivity interacting with a genetic heritage and environmental factors integrating a social context. The changing definition of posttraumatic stress disorder over time comes from scientific exploration in part determined by a sociocultural context and, reciprocally, the psychic trauma is caused by the collapse of reassuring social values which were considered as immutable. The clinical is not developed according to fixed references: the evolution of neurogenetic techniques changes our perception of psychic traumas and the therapeutic possibilities.

Post-traumatic stress disorder (PTSD) is a prevalent problem among military personnel and veterans. Identification of effective screening tools, diagnostic technologies, and treatments for PTSD is essential to ensure that all individuals in need of treatment are offered interventions with proven efficacy. Well-validated methods for screening and diagnosing PTSD are now available, and effective pharmacological and psychological treatments can be offered. Despite these advances, many military personnel and veterans do not receive evidence-based care. We review the literature on screening, diagnosis, and treatment of PTSD in military populations, and discuss the challenges to implementing the best evidence-based practices in clinical settings.

Pressure-relief and methane production performance of pressure relief gas extraction technology in the longwall mining

Zhang, Cun; Tu, Shihao; Chen, Min; Zhang, Lei

2017-02-01

Pressure relief gas extraction technology (PRGET) has been successfully implemented at many locations as a coal mine methane exploitation and outburst prevention technology. Comprehensive PRGET including gob gas venthole (GGV), crossing seam drilling hole (CSDH), large diameter horizontal long drilling hole (LDHLDH) and buried pipe for extraction (BPE) have been used to extract abundant pressure-relief methane (PRM) during protective coal seam mining; these techniques mitigated dangers associated with coal and gas outbursts in 13-1 coal seam mining in the Huainan coalfield. These extraction technologies can ensure safe protective seam mining and effectively extract coal and gas. This article analyses PRGET production performance and verifies it with the field measurement. The results showed that PRGET drilling to extract PRM from the protected coal seam significantly reduced methane emissions from a longwall ventilation system and produced highly efficient extraction. Material balance analyses indicated a significant decrease in gas content and pressure in the protected coal seam, from 8.78 m3 t-1 and 4.2 MPa to 2.34 m3 t-1 and 0.285 MPa, respectively. The field measurement results of the residual gas content in protected coal seam (13-1 coal seam) indicated the reliability of the material balance analyses and the pressure relief range of PRGET in the protected coal seam is obtained.

Relief surface changes provide interesting possibilities for storing diffractive optical elements on photopolymers and are an important source of information to characterize and understand the material behaviour. In this paper we present a 3-dimensional model based on direct measurements of parameters to predict the relief structures generated on the material. This model is successfully applied to different photopolymers with different values of monomer diffusion. The importance of monomer diffusion in depth is also discussed.

A tsunami struck the coast of Tamilnadu and Pondicherry on 26 December 2004. Jawaharlal Institute of Postgraduate Medical Education & Research, (JIPMER) in Pondicherry played a vital role in providing medical relief. The experiences from the relief activities revealed areas of deficiency in medical education in regards to disaster preparedness. A qualitative study using focus group discussion was employed to find the lacunae in skills in managing medical relief measures. Many skills were identified; the most important of which was addressing the psychological impact of the tsunami on the victims. Limited coordination and leadership skills were also identified. It is recommended that activity-based learning can be included in the curriculum to improve these skills.

Oxotremorine treatment restores hippocampal neurogenesis and ameliorates depression-like behaviour in chronically stressed rats.

Veena, J; Srikumar, B N; Mahati, K; Raju, T R; Shankaranarayana Rao, B S

2011-09-01

Chronic stress results in cognitive impairment, affects hippocampal neurogenesis and is known to precipitate affective disorders such as depression. In addition to stress, neurotransmitters such as acetylcholine (ACh) modulate adult neurogenesis. Earlier, we have shown that oxotremorine, a cholinergic muscarinic agonist, ameliorates stress-induced cognitive impairment and restores cholinergic function. In the current study, we have looked into the possible involvement of adult neurogenesis in cognitive restoration by oxotremorine. Further, we have assessed the effect of oxotremorine treatment on depression-like behaviour and hippocampal volumes in stressed animals. Chronic restraint stressed rats were treated with either vehicle or oxotremorine. For neurogenesis studies, proliferation, survival and differentiation of the progenitor cells in the hippocampus were examined using 5'-bromo-2-deoxyuridine immunohistochemistry. Depression-like behaviour was evaluated using forced swim test (FST) and sucrose consumption test (SCT). Volumes were estimated using Cavalieri's estimator. Hippocampal neurogenesis was severely decreased in stressed rats. Ten days of oxotremorine treatment to stressed animals partially restored proliferation and survival, while it completely restored the differentiation of the newly formed cells. Stressed rats showed increased immobility and decreased sucrose preference in the FST and SCT, respectively, and oxotremorine ameliorated this depression-like behaviour. In addition, oxotremorine treatment recovered the stress-induced decrease in hippocampal volume. These results indicate that the restoration of impaired neurogenesis and hippocampal volume could be associated with the behavioural recovery by oxotremorine. Our results imply the muscarinic regulation of adult neurogenesis and incite the potential utility of cholinomimetics in ameliorating cognitive dysfunction in stress-related disorders.

Female patients' and parents' assessment of deformity- and brace-related stress in the conservative treatment of adolescent idiopathic scoliosis.

A cross-sectional analysis of parents' and patients' perceptions of deformity- and brace-related stress regarding conservative treatment of adolescent idiopathic scoliosis. The purpose of this study was to determine the agreement between patients' and parents' assessments of emotional stress and to compare these assessments with radiographical measurements of spinal deformity. Conservative treatment in patients with scoliosis may cause emotional stress. To our knowledge, no group has ever reported patient and parental estimation of stress related to wearing a brace and spinal deformity in girls with adolescent idiopathic scoliosis. Sixty-three pairs of parents and girls with adolescent idiopathic scoliosis treated with a Cheneau brace were separately asked to complete the Bad Sobberheim Stress Questionnaire-Deformity and the Bad Sobberheim Stress Questionnaire-Brace. The age range of the patients was from 10 to 17 years. Patients were assessed at a mean of 14.12 (SD, 10.99) months after the start of the conservative treatment. Patients thought that a moderate level of stress was connected with conservative treatment; however, the stress level, related to perceived trunk deformation, was low. From the parents' perspective, patients experienced a moderate level of stress during conservative treatment and related to spinal deformity. The study groups differ in their perception of stress levels due to body disfigurement but not during the conservative treatment. Parent-patient stress-level disparities were not related to body mass index, age of the patient, brace application, and radiographical measurements of spinal deformity. Patients and parents perceive the emotional stress related to brace treatment in the same way; however, parents overestimate the assessment of stress levels related to body deformity. From the perspective of patients and parents, brace wearing increased the level of stress induced by the deformity alone. Complete assessment of conservative

Application of biological effective dose (BED) to estimate the duration of symptomatic relief and repopulation dose equivalent in palliative radiotherapy and chemotherapy.

PubMed

Jones, Bleddyn; Cominos, Matilda; Dale, Roger G

2003-03-01

To investigate the potential for mathematic modeling in the assessment of symptom relief in palliative radiotherapy and cytotoxic chemotherapy. The linear quadratic model of radiation effect with the overall treatment time and the daily dose equivalent of repopulation is modified to include the regrowth time after completion of therapy. The predicted times to restore the original tumor volumes after treatment are dependent on the biological effective dose (BED) delivered and the repopulation parameter (K); it is also possible to estimate K values from analysis of palliative treatment response durations. Hypofractionated radiotherapy given at a low total dose may produce long symptom relief in slow-growing tumors because of their low alpha/beta ratios (which confer high fraction sensitivity) and their slow regrowth rates. Cancers that have high alpha/beta ratios (which confer low fraction sensitivity), and that are expected to repopulate rapidly during therapy, are predicted to have short durations of symptom control. The BED concept can be used to estimate the equivalent dose of radiotherapy that will achieve the same duration of symptom relief as palliative chemotherapy. Relatively simple radiobiologic modeling can be used to guide decision-making regarding the choice of the most appropriate palliative schedules and has important implications in the design of radiotherapy or chemotherapy clinical trials. The methods described provide a rationalization for treatment selection in a wide variety of tumors.

Stress, Seizures, and Hypothalamic-Pituitary-Adrenal Axis Targets for the Treatment of Epilepsy

PubMed Central

Maguire, Jamie; Salpekar, Jay A.

2012-01-01

Epilepsy is a heterogeneous condition with multiple etiologies including genetics, infection, trauma, vascular, neoplasms, and toxic exposures. The overlap of psychiatric comorbidity adds to the challenge of optimal treatment for people with epilepsy. Seizure episodes themselves may have varying triggers; however, for decades, stress has been commonly and consistently suspected to be a trigger for seizure events. This paper explores the relationship between stress and seizures and reviews clinical data as well as animal studies that increasingly corroborate the impact of stress hormones on neuronal excitability and seizure susceptibility. The basis for enthusiasm for targeting glucocorticoid receptors for the treatment of epilepsy and the mixed results of such treatment efforts are reviewed. In addition, this paper will highlight recent findings identifying a regulatory pathway controlling the body’s physiologic response to stress which represents a novel therapeutic target for modulation of the hypothalamic-pituitary-adrenal (HPA) axis. Thus, the HPA axis may have important clinical implications for seizure control and imply use of anticonvulsants that influence this neuronal pathway. PMID:23200771

2017-01-01

Treatment guidelines for chronic pain recommend nonpharmacologic modalities as part of a comprehensive management plan. Chronic pain is common among people living with HIV/AIDS, but there is little data to guide the choice of nonpharmacologic therapies in this complex population. We performed a mixed-methods feasibility study of Mindfulness-Based Stress Reduction (MBSR) versus health education control with 32 inner city, HIV-infected participants. Outcome measures included: the Brief Pain Inventory, Perceived Stress Scale, HIV Symptoms Index, autonomic function testing, and audiotaped focus groups. Post-intervention, participants reported modest improvements in pain measures and perceived stress, but no effect of group assignment was observed. At 3-month follow-up, 79% of MBSR participants were still practicing, and pain intensity was improved, whereas in the control group pain intensity had worsened. Qualitative analysis revealed a strong sense of community in both groups, but only MBSR was perceived as useful for relaxation and pain relief.

Clinical challenges in the treatment of patients with posttraumatic stress disorder and substance abuse.

PubMed

Schäfer, Ingo; Najavits, Lisa M

2007-11-01

The aim of this article is to review the current literature on co-occuring posttraumatic stress disorder and substance-use disorder, with an emphasis on clinical aspects and emerging treatments. In clinical populations (focusing on either disorder), about 25-50% have a lifetime dual diagnosis of posttraumatic stress disorder and substance-use disorder. Patients with both disorders have a more severe clinical profile than those with either disorder alone, lower functioning, poorer well being, and worse outcomes across a variety of measures. In recent years, several promising treatment programs have been developed specifically for co-occuring posttraumatic stress disorder and substance-use disorder, with one model having been established as effective thus far. Comorbid posttraumatic stress disorder/substance-use disorder is a frequent diagnosis in clinical populations that severely affects course and outcome. Treatment approaches appropriate for this vulnerable population need to be evaluated further and implemented in routine practice.

A multi-view scanning method is suggested to assess a complicated surface relief by white light interferometer. Peculiarities of the method are demonstrated on a special object in the form of quadrangular pyramid cavity, which is formed at measurement of micro-hardness of materials using a hardness gauge. An algorithm of the joint processing of multi-view scanning results is developed that allows recovering correct relief values. Laser ablation craters were studied experimentally, and their relief was recovered using the developed method. It is shown that the multi-view scanning reduces ambiguity when determining the local depth of the laser ablation craters micro relief. Results of experimental studies of the multi-view scanning method and data processing algorithm are presented.

2016-01-01

Stress, via corticosteroids release, influences bone mass density. Hypericum perforatum (Hp) a traditional remedy possess antidepressive activity (serotonin reuptake inhibitor) and wound healing properties. Hp preparation contains mainly hypericin, hyperforin, hyperoside and flavonoids exerting oestrogen-mimetic effect. Cold swimming represents an experimental model of stress associating mental strain and corporal exhaustion. This study investigates the Hp effect on femur and mandible bone mass changes in rats under cold forced swimming procedure. 30 male Wistar rats were randomized into three groups. Group A was treated with Methanolic extract of Hp (Jarsin®) via gastroesophageal catheter, and was submitted to cold swimming stress for 10 min/daily. Group B was submitted to cold stress, since group C served as control. Experiment duration was 10 days. Haematocrite and serum free fatty acids (FFA) were estimated. Furthermore volume and specific weight of each bone as well as bone mass density via dual energy X-Ray absorptiometry (DEXA) were measured. Statistic analysis by t-test. Hp treatment restores the stress injuries. Adrenals and bone mass density regain their normal values. Injuries occurring by forced swimming stress in the rats are significantly improved by Hp treatment. Estrogen-like effects of Hp flavonoids eventually may act favorable in bone remodeling.

Patient expectations predict greater pain relief with joint arthroplasty.

PubMed

Gandhi, Rajiv; Davey, John Roderick; Mahomed, Nizar

2009-08-01

We examined the relationship between patient expectations of total joint arthroplasty and functional outcomes. We surveyed 1799 patients undergoing primary hip or knee arthroplasty for demographic data and Western Ontario McMaster University Osteoarthritis Index scores at baseline, 3 months, and 1 year of follow-up. Patient expectations were determined with 3 survey questions. The patients with the greatest expectations of surgery were younger, male, and had a lower body mass index. Linear regression modeling showed that a greater expectation of pain relief with surgery independently predicted greater reported pain relief at 1 year of follow-up, adjusted for all relevant covariates (P < .05). Patient expectation of pain relief after joint arthroplasty is an important predictor of outcomes at 1 year.

Cytogenetic Effects of Chronic Methylphenidate Treatment and Chronic Social Stress in Adults with Attention-Deficit/Hyperactivity Disorder.

2016-07-01

Methylphenidate (MPH) is widely used to treat childhood and adult attention-deficit/hyperactivity disorder (ADHD). However, there are still safety concerns about side effects in long-term treatment. The aim of this study was to assess cytogenetic effects of chronic MPH treatment in adult ADHD and to find out if chronic social stress is attenuated by medication and to investigate whether chronic psychosocial stress leads to mutagenic effects by itself. Lymphocytes for micronucleus assay and saliva samples for cortisol measurement were collected from adult ADHD patients and healthy controls. Stress exposure of the last 3 months was assessed by TICS (Trier Inventory for Chronic Stress). We could not detect an influence of MPH treatment on cytogenetic markers. ADHD patients displayed significantly higher chronic stress levels measured by TICS compared to healthy controls which were influenced by duration of MPH treatment. ADHD patients also showed significantly lower basal cortisol levels. We could corroborate that there are neither cytogenetic effects of chronic stress nor of chronic MPH intake even after several years of treatment. © Georg Thieme Verlag KG Stuttgart · New York.

A Transdiagnostic Minority Stress Treatment Approach for Gay and Bisexual Men’s Syndemic Health Conditions

PubMed Central

Pachankis, John E.

2015-01-01

Developing and deploying separate treatments for separate conditions seems ill-suited to intervening upon the co-occurring, and possibly functionally similar, psychosocial conditions facing gay and bisexual men. This article argues for the need to create transdiagnostic interventions that reduce multiple syndemic conditions facing gay and bisexual men at the level of their shared source in minority stress pathways. This article first reviews psychosocial syndemic conditions affecting gay and bisexual men, then suggests pathways that might link minority stress to psychosocial syndemics based on recent advancements in emotion science, psychiatric nosology, and cognitive-affective neuroscience, and finally suggests cross-cutting psychosocial treatment principles to reduce minority stress–syndemic pathways among gay and bisexual men. Because minority stress serves as a common basis of all psychosocial syndemic conditions reviewed here, locating the pathways through which minority stress generates psychosocial syndemics and employing overarching treatment principles capable of simultaneously alleviating these pathways will ultimately create a transdiagnostic approach to improving gay and bisexual men’s health. Clinical research and training approaches are suggested to further validate the pathways suggested here, establish the efficacy of treatment approaches tied to those pathways, and generate effective methods for disseminating a transdiagnostic minority stress treatment approach for gay and bisexual men’s psychosocial syndemic health.

Oxidative stress in the pathology and treatment of systemic lupus erythematosus.

PubMed

Perl, Andras

2013-11-01

Oxidative stress is increased in systemic lupus erythematosus (SLE), and it contributes to immune system dysregulation, abnormal activation and processing of cell-death signals, autoantibody production and fatal comorbidities. Mitochondrial dysfunction in T cells promotes the release of highly diffusible inflammatory lipid hydroperoxides, which spread oxidative stress to other intracellular organelles and through the bloodstream. Oxidative modification of self antigens triggers autoimmunity, and the degree of such modification of serum proteins shows striking correlation with disease activity and organ damage in SLE. In T cells from patients with SLE and animal models of the disease, glutathione, the main intracellular antioxidant, is depleted and serine/threonine-protein kinase mTOR undergoes redox-dependent activation. In turn, reversal of glutathione depletion by application of its amino acid precursor, N-acetylcysteine, improves disease activity in lupus-prone mice; pilot studies in patients with SLE have yielded positive results that warrant further research. Blocking mTOR activation in T cells could conceivably provide a well-tolerated and inexpensive alternative approach to B-cell blockade and traditional immunosuppressive treatments. Nevertheless, compartmentalized oxidative stress in self-reactive T cells, B cells and phagocytic cells might serve to limit autoimmunity and its inhibition could be detrimental. Antioxidant therapy might also be useful in ameliorating damage caused by other treatments. This Review thus seeks to critically evaluate the complexity of oxidative stress and its relevance to the pathogenesis and treatment of SLE.

Update on stress fractures in female athletes: epidemiology, treatment, and prevention.

Chen, Yin-Ting; Tenforde, Adam S; Fredericson, Michael

2013-06-01

Stress fractures are a common type of overuse injury in athletes. Females have unique risk factors such as the female athlete triad that contribute to stress fracture injuries. We review the current literature on risk factors for stress fractures, including the role of sports participation and nutrition factors. Discussion of the management of stress fractures is focused on radiographic criteria and anatomic location and how these contribute to return to play guidelines. We outline the current recommendations for evaluating and treatment of female athlete triad. Technologies that may aid in recovery from a stress fracture including use of anti-gravity treadmills are discussed. Prevention strategies may include early screening of female athlete triad, promoting early participation in activities that improve bone health, nutritional strategies, gait modification, and orthotics.

Gardening promotes neuroendocrine and affective restoration from stress.

PubMed

Van Den Berg, Agnes E; Custers, Mariëtte H G

2011-01-01

Stress-relieving effects of gardening were hypothesized and tested in a field experiment. Thirty allotment gardeners performed a stressful Stroop task and were then randomly assigned to 30 minutes of outdoor gardening or indoor reading on their own allotment plot. Salivary cortisol levels and self-reported mood were repeatedly measured. Gardening and reading each led to decreases in cortisol during the recovery period, but decreases were significantly stronger in the gardening group. Positive mood was fully restored after gardening, but further deteriorated during reading. These findings provide the first experimental evidence that gardening can promote relief from acute stress.

Modeling the onset and offset of dental pain relief by ibuprofen.

2012-01-01

Onset and offset of dental pain relief by ibuprofen following third molar extraction were modeled in a randomized, double-blind, placebo-controlled, parallel-group, 8-hour study of patients receiving either a novel effervescent ibuprofen tablet (400 mg; N = 30), standard ibuprofen tablets (Nurofen(®) 2 × 200 mg; N = 22), or placebo (N = 37). An Emax model was fit to pain relief scores. Linear hazard models were used to analyze the time to first perceptible relief (TFPR), the time to meaningful pain relief (TMPR), and time to remedication (REMD). Nomograms were created to correlate TFPR, TMPR, and REMD with different ibuprofen pharmacokinetic profiles. Effervescent ibuprofen was absorbed rapidly with 95% completion within 15 minutes. Maximum pain relief score by ibuprofen was 1.8 units greater than placebo, with an EC50 (effect-site) for ibuprofen concentration of 10.2 µg·mL(-1). The likelihood to achieve TFPR and TMPR was doubled for every 10 µg·mL(-1) increase in ibuprofen plasma concentration. REMD risk decreased 40-fold as the categorical pain relief score increased from 0 to 3. Rapid absorption of ibuprofen effervescent resulted in an earlier TFPR and TMPR, and a lower REMD rate than standard ibuprofen. The nomograms may be useful in predicting the onset and offset of new faster acting ibuprofen formulations, based on pharmacokinetic profiles.

Between 60 and 90% of patients consult their family doctor for stress-associated complaints. Not infrequently, a considerable number of these patients already have elevated blood pressure. The positive effect on high blood pressure of relaxation techniques has been confirmed in various studies. Accordingly, stress management should now have a permanent place in effective antihypertensive treatment. Appropriate relaxation techniques include, for example, autogenic training, progressive muscle relaxation, visualization and breathing exercises, chi gong and yoga. These practices are incorporated in various lifestyle programs. They act in different ways, and can be offered to the patient in accordance with his/her individual wishes.

Stereopsis, vertical disparity and relief transformations.

Gårding, J; Porrill, J; Mayhew, J E; Frisby, J P

1995-03-01

The pattern of retinal binocular disparities acquired by a fixating visual system depends on both the depth structure of the scene and the viewing geometry. This paper treats the problem of interpreting the disparity pattern in terms of scene structure without relying on estimates of fixation position from eye movement control and proprioception mechanisms. We propose a sequential decomposition of this interpretation process into disparity correction, which is used to compute three-dimensional structure up to a relief transformation, and disparity normalization, which is used to resolve the relief ambiguity to obtain metric structure. We point out that the disparity normalization stage can often be omitted, since relief transformations preserve important properties such as depth ordering and coplanarity. Based on this framework we analyse three previously proposed computational models of disparity processing; the Mayhew and Longuet-Higgins model, the deformation model and the polar angle disparity model. We show how these models are related, and argue that none of them can account satisfactorily for available psychophysical data. We therefore propose an alternative model, regional disparity correction. Using this model we derive predictions for a number of experiments based on vertical disparity manipulations, and compare them to available experimental data. The paper is concluded with a summary and a discussion of the possible architectures and mechanisms underling stereopsis in the human visual system.

Detachment-limited erosion, alluvial transport, and relief in decaying landscapes

NASA Astrophysics Data System (ADS)

Johnstone, S. A.; Hilley, G. E.

2013-12-01

The correspondence between relief and erosion rates in tectonically active orogens suggests that erosion rates and relief adjust relatively rapidly to changes in the rates of tectonic processes. This rapid landscape response is at odds with the preservation of ancient orogens for 10s to 100s of millions of years after orogenesis has ceased. We hypothesize that this hysteresis in response times to the acceleration versus deceleration of tectonic rates results from a geomorphic process transition in fluvial networks. In steep landscapes found in tectonically active environments erosion is largely controlled by detachment-limited incision, whereas the increasing importance of alluvial transport in decaying landscapes controls relief and response time-scales in these situations. We present results from one-dimensional (profile) numerical modeling of channels undergoing topographic decay from an initial steady state following a cessation in uplift to understand process transitions that may reconcile the large differences in response times implied by active versus ancient mountain-belts. We performed dimensional analysis on the governing equations such that relief in the channels, process transitions between alluvial transport and detachment-limited erosion, and response times could be viewed in terms of dimensionless numbers that capture the relative strength of sediment transport, bedrock incision, and the initial uplift rate. We found that the form of the decaying profile is dictated by the relative ability of a system to incise vs. transport sediment. When sediment transport is inefficient relative to bedrock incision, models suggest that relief decays in a manner that preserves the overall channel profile geometry as channel slopes decline. In contrast, when the ability of a system to transport sediment greatly exceeds its ability to incise bedrock, decay will be dominated by the consumption of topography by slope retreat. We find that the declivity of the surface

Emergency relief venting of the infrared telescope liquid helium dewar, second edition

NASA Technical Reports Server (NTRS)

Urban, E. W.

1981-01-01

An updated analysis is made of the emergency relief venting of the liquid helium dewar of the Spacelab 2 Infrared Telescope experiment in the event of a massive failure of the dewar guard vacuum. Such a failure, resulting from a major accident, could cause rapid heating and pressurization of the liquid helium in the dewar and lead to relief venting through the emergency relief system. The heat input from an accident is estimated for various fluid conditions in the dewar and the relief process considered as it takes place through one or both of the emergency relief paths. It was previously assumed that the burst diaphragms in the dewar relief paths would rupture at a pressure of 65 psi differential or 4.4 atmospheres. In fact, it has proved necessary to use burst diaphragms in the dewar which rupture at 115 psid or 7.8 atmospheres. An analysis of this case was carried out and shows that when the high pressure diaphragm rupture occurs, the dewar pressure falls within 8 s to below the 4.4 atmospheres for which the original analysis was performed, and thereafter it remains below that level.

Shaded Relief of Rio Sao Francisco, Brazil

NASA Image and Video Library

2000-02-14

This topographic image acquired by SRTM shows an area south of the Sao Francisco River in Brazil. The scrub forest terrain shows relief of about 400 meters (1300 feet). Areas such as these are difficult to map by traditional methods because of frequent cloud cover and local inaccessibility. This region has little topographic relief, but even subtle changes in topography have far-reaching effects on regional ecosystems. The image covers an area of 57 km x 79 km and represents one quarter of the 225 km SRTM swath. Colors range from dark blue at water level to white and brown at hill tops. The terrain features that are clearly visible in this image include tributaries of the Sao Francisco, the dark-blue branch-like features visible from top right to bottom left, and on the left edge of the image, and hills rising up from the valley floor. The San Francisco River is a major source of water for irrigation and hydroelectric power. Mapping such regions will allow scientists to better understand the relationships between flooding cycles, forestation and human influences on ecosystems. This shaded relief image was generated using topographic data from the Shuttle Radar Topography Mission. A computer-generated artificial light source illuminates the elevation data to produce a pattern of light and shadows. Slopes facing the light appear bright, while those facing away are shaded. On flatter surfaces, the pattern of light and shadows can reveal subtle features in the terrain. Shaded relief maps are commonly used in applications such as geologic mapping and land use planning. http://photojournal.jpl.nasa.gov/catalog/PIA02700

Effectiveness of Cannabidiol Oil for Pediatric Anxiety and Insomnia as Part of Posttraumatic Stress Disorder: A Case Report.

PubMed

Shannon, Scott; Opila-Lehman, Janet

2016-01-01

Anxiety and sleep disorders are often the result of posttraumatic stress disorder and can contribute to an impaired ability to focus and to demonstration of oppositional behaviors. These symptoms were present in our patient, a ten-year-old girl who was sexually abused and had minimal parental supervision as a young child under the age of five. Pharmaceutical medications provided partial relief, but results were not long-lasting, and there were major side effects. A trial of cannabidiol oil resulted in a maintained decrease in anxiety and a steady improvement in the quality and quantity of the patient's sleep. Cannabidiol oil, an increasingly popular treatment of anxiety and sleep issues, has been documented as being an effective alternative to pharmaceutical medications. This case study provides clinical data that support the use of cannabidiol oil as a safe treatment for reducing anxiety and improving sleep in a young girl with posttraumatic stress disorder.

Topology-optimized broadband surface relief transmission grating

NASA Astrophysics Data System (ADS)

Andkjær, Jacob; Ryder, Christian P.; Nielsen, Peter C.; Rasmussen, Thomas; Buchwald, Kristian; Sigmund, Ole

2014-03-01

We propose a design methodology for systematic design of surface relief transmission gratings with optimized diffraction efficiency. The methodology is based on a gradient-based topology optimization formulation along with 2D frequency domain finite element simulations for TE and TM polarized plane waves. The goal of the optimization is to find a grating design that maximizes diffraction efficiency for the -1st transmission order when illuminated by unpolarized plane waves. Results indicate that a surface relief transmission grating can be designed with a diffraction efficiency of more than 40% in a broadband range going from the ultraviolet region, through the visible region and into the near-infrared region.

AIMS: To investigate changes in morphology of the developmental stages of Enterocytozoon bieneusi and symptomatic relief observed in AIDS patients after treatment with furazolidone. METHODS: Six AIDS patients with symptomatic E bieneusi infection of the small intestine were treated with a course of furazolidone. All patients had a weekly monitoring of parasite shedding in stool by light microscopy during and after treatment. At the end of the treatment, duodenal biopsy specimens obtained from three patients were studied by transmission electron microscopy by two pathologists who were unaware of the patients' treatment. RESULTS: All patients showed both clinical and parasitological response with transient clearance or decrease of spore shedding in stool. After treatment, alterations in faecal spores were observed in all patients by light microscopy, and ultrastructural changes in E bieneusi at all stages of the life cycle were demonstrated in biopsy specimens of the three patients who underwent post-treatment endoscopy. CONCLUSIONS: The clinical benefit seen after treatment with furazolidone in six AIDS patients with E bieneusi intestinal infection may be due to damage to the developmental stages causing a partial inhibition to reproduction of the parasite.

The involvement of cholinergic and noradrenergic systems in behavioral recovery following oxotremorine treatment to chronically stressed rats.

PubMed

Srikumar, B N; Raju, T R; Shankaranarayana Rao, B S

2006-12-01

Chronic stress in rats has been shown to impair learning and memory, and precipitate several affective disorders like depression and anxiety. The mechanisms involved in these stress-induced disorders and the possible reversal are poorly understood, thus limiting the number of drugs available for their treatment. Our earlier studies suggest cholinergic dysfunction as the underlying cause in the behavioral deficits following stress. Muscarinic cholinergic agonist, oxotremorine is demonstrated to have a beneficial effect in reversing brain injury-induced behavioral dysfunction. In this study, we have evaluated the effect of oxotremorine treatment on chronic restraint stress-induced cognitive deficits. Rats were subjected to restraint stress (6 h/day) for 21 days followed by oxotremorine treatment for 10 days. Spatial learning and memory was assessed in a partially baited eight-arm radial maze task. Stressed rats exhibited impairment in performance, with decreased percentage of correct choices and an increase in the number of reference memory errors (RMEs). Oxotremorine treatment (0.1 or 0.2 mg/kg, i.p.) to stressed rats resulted in a significant increase in the percent correct choices and a decrease in the number of RMEs compared with stress as well as the stress+vehicle-treated groups. In the retention test, oxotremorine treated rats committed less RMEs compared with the stress group. Chronic restraint stress decreased acetylcholinesterase (AChE) activity in the hippocampus, frontal cortex and septum, which was reversed by both the doses of oxotremorine. Further, oxotremorine treatment also restored the norepinephrine levels in the hippocampus and frontal cortex. Thus, this study demonstrates the potential of cholinergic muscarinic agonists and the involvement of both cholinergic and noradrenergic systems in the reversal of stress-induced learning and memory deficits.

Processes of holographic recording of surface relief structures using As 2 S 3 :Mn-Se multilayer nanostructures as registering media were studied in this paper. Optical properties of As 2 S 3 :Mn, Se layers, and As 2 S 3 :Mn-Se multilayer nanostructures were investigated. Values of optical bandgaps were obtained from Tauc dependencies. Surface relief diffraction gratings were recorded. Direct one-stage formation of surface relief using multilayer nanostructures is considered. For the first time, possibility of direct formation of magnetic relief simultaneous with surface relief formation under optical recording using As 2 S 3 :Mn-Se multilayer nanostructures is shown.

Pain control has been emphasized as a priority for both practitioners and inpatients with rib fractures, since analgesia could only offer limited relief from severe pain. A prospective and randomized controlled trial was conducted to analyze the efficacy and efficiency of acupuncture in acute pain relief for inpatients with rib fractures. A total of 58 inpatients were recruited and allocated to two groups, receiving identical doses of conventional oral analgesics as well as filiform needles as treatment and thumbtack intradermal (TI) needles placed upon the skin surface as a control, respectively, via novel acupuncture modality once daily for three consecutive days. The effect of pain relief was evaluated during activities that induce pain, and sustained maximal inspiration (SMI) lung volumes and sleep quality were assessed. The patients treated with filiform needles had more effective pain relief than those in the TI needle group during deep breathing, coughing, and turning over the body (p < 0.05), and the effect persisted for at least 6 h in most patients. Sustained maximal inspiration lung volumes and sleep quality did not show improvement through every acupuncture intervention, and they could not respond accurately to pain relief via acupuncture. The active evaluation could provide a more adaptive model for assessing pain intensity due to rib fractures. This novel acupuncture modality in which the needle insertion sites are corresponding to the pain spots can be a safe and viable therapy for relieving pain in inpatients with rib fractures.

Pasireotide is a new-generation somatostatin analog that acts through binding to multiple somatostatin receptor subtypes. Studies have shown that pasireotide induces hyperglycemia, reduces glucocorticoid secretion, alters neurotransmission, and potentially affects stress responses typically manifested as hyperglycemia and increased corticosterone secretion. This study specifically aimed to evaluate whether pasireotide treatment modifies glucose and costicosterone secretion in response to acute restraint stress. Male Holtzman rats of 150-200 g were treated with pasireotide (10 µg/kg/day) twice-daily for two weeks or vehicle for the same period. Blood samples were collected at baseline and after 5, 10, 30, and 60 min of restraint stress. The three experimental groups comprised of vehicle + restraint (VEHR), pasireotide + restraint (PASR), and pasireotide + saline (PASNR). Following pasireotide treatment, no significant differences in baseline glucose and corticosterone levels were observed among the three groups. During restraint, hyperglycemia was observed at 10 min (p < .01 for both comparisons), peaked at 30 min (p < .01 for both comparisons) and showed higher 60 min areas under glucose curves in the VEHR and PASR stressed groups when compared to the non-stressed PASNR group (p < .05 for both comparisons). Restraint also increased corticosterone secretion in the VEHR and PASR stressed groups at 5 min (p < .01 for both comparisons), and peaked at 30 min (p < .01 for both comparisons) with corresponding higher 60 min areas under corticosterone curves when compared to the non-stressed PASNR group (p < .01 for both comparisons). In conclusion, pasireotide treatment does not modify hyperglycemic- and corticosterone-restraint stress responses, thus preserving acute stress regulation.

Ti-6Al-4V bridges were additively fabricated by selective laser melting (SLM) under different scanning speed conditions, to compare the effect of process energy density on the residual stress state. Subsurface lattice strain characterization was conducted by means of synchrotron diffraction in energy dispersive mode. High tensile strain gradients were found at the frontal surface for samples in an as-built condition. The geometry of the samples promotes increasing strains towards the pillar of the bridges. We observed that the higher the laser energy density during fabrication, the lower the lattice strains. A relief of lattice strains takes place after heat treatment. PMID:28772706

Inventory slack routing application in emergency logistics and relief distributions.

2018-01-01

Various natural and manmade disasters during last decades have highlighted the need of further improving on governmental preparedness to emergency events, and a relief supplies distribution problem named Inventory Slack Routing Problem (ISRP) has received increasing attentions. In an ISRP, inventory slack is defined as the duration between reliefs arriving time and estimated inventory stock-out time. Hence, a larger inventory slack could grant more responsive time in facing of various factors (e.g., traffic congestion) that may lead to delivery lateness. In this study, the relief distribution problem is formulated as an optimization model that maximize the minimum slack among all dispensing sites. To efficiently solve this problem, we propose a two-stage approach to tackle the vehicle routing and relief allocation sub-problems. By analyzing the inter-relations between these two sub-problems, a new objective function considering both delivery durations and dispensing rates of demand sites is applied in the first stage to design the vehicle routes. A hierarchical routing approach and a sweep approach are also proposed in this stage. Given the vehicle routing plan, the relief allocation could be easily solved in the second stage. Numerical experiment with a comparison of multi-vehicle Traveling Salesman Problem (TSP) has demonstrated the need of ISRP and the capability of the proposed solution approaches.

Treatment of tibial stress fractures in elite dancers is centered on rest and activity modification. Surgical intervention in refractory cases has important implications affecting the dancers' careers. Refractory tibial stress fractures in dancers can be treated successfully with drilling and bone grafting or intramedullary nailing. Case series; Level of evidence, 4. Between 1992 and 2006, 1757 dancers were evaluated at a dance medicine clinic; 24 dancers (1.4%) had 31 tibial stress fractures. Of that subset, 7 (29.2%) elite dancers with 8 tibial stress fractures were treated operatively with either intramedullary nailing or drilling and bone grafting. Six of the patients were followed up closely until they were able to return to dance. One patient was available only for follow-up phone interview. Data concerning their preoperative treatment regimens, operative procedures, clinical union, radiographic union, and time until return to dance were recorded and analyzed. The mean age of the surgical patients at the time of stress fracture was 22.6 years. The mean duration of preoperative symptoms before surgical intervention was 25.8 months. Four of the dancers were male and 3 were female. All had failed nonoperative treatment regimens. Five patients (5 tibias) underwent drilling and bone grafting of the lesion, and 2 patients (3 tibias) with completed fractures or multiple refractory stress fractures underwent intramedullary nailing. Clinical union was achieved at a mean of 6 weeks and radiographic union at 5.1 months. Return to full dance activity was at an average of 6.5 months postoperatively. Surgical intervention for tibial stress fractures in dancers who have not responded to nonoperative management allowed for resolution of symptoms and return to dancing with minimal morbidity.

This paper examines failure of helical gear in speed increasing gearbox used in the wind turbine generator (WTG). In addition, an attempt has been made to get suitable gear micro-geometry such as pressure angle and tip relief to minimize the gear failure in the wind turbines. As the gear trains in the wind turbine gearbox is prearranged with higher speed ratio and the gearboxes experience shock load due to atmospheric turbulence, gust wind speed, non-synchronization of pitching, frequent grid drops and failure of braking, the gear failure occurs either in the intermediate or high speed stage pinion. KISS soft gear calculation software was used to determine the gear specifications and analysis is carried out in ANSYS software version.11.0 for the existing and the proposed gear to evaluate the performance of bending stress tooth deflection and stiffness. The main objective of this research study is to propose suitable gear micro-geometry that is tip relief and pressure angle blend for increasing tooth strength of the helical gear used in the wind turbine for trouble free operation.

Measuring Paleolandscape Relief in Alluvial River Systems from the Stratigraphic Record

Aggradational alluvial river systems sometimes generate relief in the vicinity of their channel belts (i.e. alluvial ridges) and it has been proposed that this process may define important thresholds in river avulsion. The compensation scale can be used to estimate the maximum relief across a landscape and can be connected to the maximum scale of autogenic organization in experimental and numerical systems. Here we use the compensation scale - measured from outcrops of Upper Cretaceous and Paleogene fluvial deposits - to estimate the maximum relief that characterized ancient fluvial landscapes. In some cases, the compensation scale significantly exceeds the maximum channel depth observed in a deposit, suggesting that aggradational alluvial systems organize to sustain more relief than might be expected by looking only in the immediate vicinity of the active channel belt. Instead, these results indicate that in some systems, positive topographic relief generated by multiple alluvial ridge complexes and/or large-scale fan features may be associated with landscape-scale autogenic organization of channel networks that spans multiple cycles of channel avulsion. We compare channel and floodplain sedimentation patterns among the studied ancient fluvial systems in an effort to determine whether avulsion style, channel migration, or floodplain conditions influenced the maximum autogenic relief of ancient landscapes. Our results emphasize that alluvial channel networks may be organized at much larger spatial and temporal scales than previously realized and provide an avenue for understanding which types of river systems are likely to exhibit the largest range of autogenic dynamics.
