Background Patients trying life-preserving agents such as beta-blockers may be discouraged by listings of harmful effects provided in good faith by doctors, drug information sheets, and media. We systematically review the world experience of side-effect information in blinded, placebo-controlled beta-blockade in heart failure. We present information for a physician advising a patient experiencing an unwanted symptom and suspecting the drug. Methods We searched Medline for double-blinded randomized trials of beta-blocker versus placebo in heart failure reporting side-effects. We calculated, per 100 patients reporting the symptom on beta-blockade, how many would have experienced it on placebo: the “proportion of symptoms non-pharmacological”. Results 28 of the 33 classically-described side-effects are not significantly more common on beta-blockers than placebo. Of the 100 patients developing dizziness on beta-blockers, 81 (95% CI 73–89) would have developed it on placebo. For diarrhoea this proportion is 82/100 (70–95), and hyperglycaemia 83/100 (68–98). For only two side-effects is this under half (i.e. predominantly due to beta-blocker): bradycardia (33/100, CI 21–44) and intermittent claudication (41/100, 2–81). At least 6 so-called side-effects are less common on beta-blocker than placebo, including depression (reduced by 35%, p < 0.01) and insomnia (by 27%, p = 0.01). Conclusions Clinicians might reconsider whether it is scientifically and ethically correct to warn a patient that a drug might cause them a certain side-effect, when randomized controlled trials show no significant increase, or indeed a significant reduction. A better informed consultation could, in patients taking beta-blockers, alleviate suffering. In patients who might otherwise not take the drug, it might prevent deaths. PMID:23796325

Drug therapy is the mainstay of treatment for overactive bladder (OAB), but antimuscarinic agents possess side-effects. These side-effects decrease the patients' quality of life. We therefore assessed the impact of side-effects on health-related quality of life (HR-QoL) through an analysis of EQ-5D questionnaire. This study was designed to investigate the patients' satisfaction by quality weight of health status as affected by the side-effects of OAB medications. Patients who had OAB symptoms lasting longer than 3 months and have experienced side-effects after any antimuscarinic treatments filled in the EQ-5D questionnaire. The enrolled patients had two EQ-5D questionnaires for two different health statuses, i.e., presence or absence of side-effects. Quality weight was calculated using the ED-5D health status score with Korean tariff. One hundred patients were enrolled and completed the HR-QoL questionnaire. The most prevalent side-effect was dry mouth (61%) and 28% patients had dry mouth and constipation concurrently. Most of the patients with side-effects tried to endure and overcome these side-effects (79%), but 10% desired a change in medication, and 6% stopped medication altogether. The quality weight of EQ-5D without side-effects was 0.863, while the quality weight with side-effects was 0.666 (P < 0.001). The VAS score was 79 in patient without side-effects and 57 in those with side-effects, supporting the results of quality weight assessment. Overactive bladder patients may enjoy a better quality of life if side-effects associated with antimuscarinic therapy are fewer. © 2016 John Wiley & Sons Australia, Ltd.

Adherence to attention deficit hyperactivity disorder (ADHD) treatment is important because, when untreated, it may have serious consequences with lifelong effects. In the case of adolescents on long-term medicine prescription, more knowledge is needed regarding adherence and factors influencing adherence, which was the purpose of this study. Adolescents (n = 101) on ADHD medication ≥6 months were administrated questionnaires at a monitoring appointment: Medication Adherence Report Scale (MARS), beliefs about medicines (BMQ) and the Brief Illness Perception Questionnaire (B-IPQ). Adherence was high, the mean value was 88% of the maximum MARS score, and correlated positively with the "BMQ-necessity-concerns differential" but negatively with "BMQ-concerns" and "BMQ-side effects". Adolescents with more belief in the necessity of the medication, less concerns and less experience of side effects tended to be more adherent to medication prescription ("intentional non-adherence"), while "unintentional non-adherence" (forgetfulness) was associated with how much they perceived that their ADHD affected their lives. In a multiple regression model, the variance of MARS total (R 2  = 0.21) and "intentional non-adherence" (R 2  = 0.24) was explained by the "BMQ-necessity-concern differential" and "BMQ-experienced side effects". The variance of "unintentional non-adherence" (R 2  = 0.12) was explained by the "BMQ-necessity-concern differential" and "B-IPQ-consequences of ADHD". In conclusion, adolescents on long-term medication reported good adherence, mainly influenced by more beliefs in the necessity versus concerns of the medications, less experienced side effects and more perceived consequences of ADHD. BMQ could be useful to identify risks of low adherence, which should be counteracted by partially gender-specific interventions.

To establish how the terms recommended by the European Commission to describe side-effect risk in patient information leaflets (PILs) influences expectations of side-effects and to identify factors associated with these side-effect expectations. A cross-sectional online survey was carried out by a market research company. Data were collected in England between 18th March and 1st April 2016. A total of 1003 adults aged between 18 and 65. Self-reported expectation that the described side-effects would affect participants if they took the medicine, measured on a likelihood scale from 1 (very unlikely) to 5 (very likely). Participants formed high expectations of side-effects for "very common" and "common" side-effects, with 51.9% and 45.0% of participants rating these as "very likely" or "likely" to happen to them, respectively. This fell to 8.1% for "uncommon," 5.8% for "rare" and 4.1% for "very rare." For each descriptor, higher expectations of side-effects were more associated with women or being from an ethnic minority, or having less education, a household illness, high perceived sensitivity to medicines or negative beliefs about medicines. The current use of verbal descriptors to communicate side-effect risk in PILs leads to high side-effect expectations. These expectations could contribute to nocebo-induced medication side-effects experienced by patients. Additional work is required to identify ways to improve the way risk information is conveyed in PILs. © 2017 The Authors Health Expectations Published by John Wiley & Sons Ltd.

The effect of qualifying language on perceptions of drug appeal, drug experience, and estimates of side-effect incidence in DTC advertising.

PubMed

Davis, Joel

2007-01-01

This study examined how the use of qualifying language in direct-to-consumer (DTC) pharmaceutical advertising affects consumers' perceptions of drug appeal, anticipated pleasantness of drug usage, and the expected incidence of side-effect occurrence. A sample of 669 individuals participated in a 2 x 8 complete factorial design. The design manipulated the number of side effects associated with drug use and the type of qualifying language used to describe the side effects. The eight experimental qualifying language cells represented one control condition (no qualifying language), three cells where each of three types of qualifying language were presented individually, and four cells where qualifying language was combined. The results indicate that qualifying language has a profound effect on drug perceptions, especially when used in combination. Drug appeal and the anticipated drug-using experience almost always were more positive in the presence of qualifying language. Qualifying language appears to exert its influence by causing individuals to reduce their estimate of the likelihood of experiencing individual side effects. Policy implications of the research, particularly for evaluation of "fair balance" and the reporting of side effects, are presented.

Targeted therapies (TTs), notably trastuzumab, have improved outcomes for breast cancer characterised by overexpression of human epidermal growth factor receptors including HER2. Compared with chemotherapy treatments, TTs are more specific in their targets and are delivered over longer periods of time, thus presenting different side-effect profiles. The objective of this paper is to systematically review and describe the side effects associated with TTs used in the adjuvant and metastatic settings for HER2+ breast cancer. The MEDLINE, EMBASE, CINAHL, Web of Science and Cochrane Library databases were searched from January 2007 to March 2015 to identify clinical trials and prospective studies reporting toxicities associated with TTs (mainly trastuzumab and lapatinib) used without other therapies in the treatment of HER2-positive breast cancer. Two independent reviewers selected papers based on their titles and abstracts. All papers selected by either reviewer were included. A third reviewer extracted and tabulated the relevant data using a data extraction form. We identified 5478 papers, of which 299 were reviewed and 18 trials identified involving 6980 patients. A total of 66 side effects were identified, including 46 "patient-based" symptoms and 20 "medically defined" outcomes. Side effects were more common for patients treated with therapies other than trastuzumab or with dual-HER2 regimens and for patients with metastatic disease. Diarrhoea and skin rash were the most prevalent symptoms, experienced by 29 % and 22 % of patients overall, respectively. There were 119 (2 %) cardiac events reported, and these were not exclusive to trastuzumab-treated patients. The majority of side effects (n = 52) were experienced by 1 % or less of patients and were predominantly of grade 1/2 toxicity. This systematic review provides a detailed analysis of side effects of HER2+ therapies in a large number of patients included in trials, enabling an accurate estimate of prevalence and a complete understanding of the patients' experience. This will help clinicians and patients in treatment planning.

Negative physiological stimulation and sedation side effects are experienced by a significant proportion of consumers who consume alcohol mixed with energy drinks (AmED). Few studies have compared the frequency of side effects between sessions of AmED and sessions of alcohol only within-subject, and none have explored a dose relationship. Explore the occurrence of self-reported physiological stimulant and sedative side effects between sessions of AmED and alcohol only, and at varying ED dosage levels within AmED sessions. A convenience sample of 2953 residents of New South Wales, Australia completed an online survey. N=731 AmED users reported daily caffeine intake, typical alcohol and AmED consumption, and past 12-month experience of physiological stimulation and sedation side effects during AmED and alcohol only sessions. Within-subject analyses compared occurrence of side effects between session types. Hierarchical binary logistic regression analyses explored the association of ED dose during AmED sessions with the experience of physiological side effects. There were greater odds of most stimulant side effects, and lower odds of sedation side effects, during AmED sessions compared to alcohol only sessions. Compared to one ED, consumption of three or more EDs was significantly associated with the majority of both stimulant and alcohol intoxication side effects after controlling for demographics and consumption covariates. AmED is associated with perceived changes in physiological stimulant and sedation side effects of alcohol. Experience of side effects is positively associated with ED dosage. Future research should account for varying ED dosage, and reflect real world consumption levels. Copyright © 2017 Elsevier Ltd. All rights reserved.

Capturing service users' perspectives can highlight additional and different concerns to those of clinicians, but there are no up to date, self-report psychometrically sound measures of side effects of antipsychotic medications. Aim To develop a psychometrically sound measure to identify antipsychotic side effects important to service users, the Maudsley Side Effects (MSE) measure. An initial item bank was subjected to a Delphi exercise (n = 9) with psychiatrists and pharmacists, followed by service user focus groups and expert panels (n = 15) to determine item relevance and language. Feasibility and comprehensive psychometric properties were established in two samples (N43 and N50). We investigated whether we could predict the three most important side effects for individuals from their frequency, severity and life impact. MSE is a 53-item measure with good reliability and validity. Poorer mental and physical health, but not psychotic symptoms, was related to side-effect burden. Seventy-nine percent of items were chosen as one of the three most important effects. Severity, impact and distress only predicted 'putting on weight' which was more distressing, more severe and had more life impact in those for whom it was most important. MSE is a self-report questionnaire that identifies reliably the side-effect burden as experienced by patients. Identifying key side effects important to patients can act as a starting point for joint decision making on the type and the dose of medication.

Body-drug assemblages: theorizing the experience of side effects in the context of HIV treatment.

Gagnon, Marilou; Holmes, Dave

2016-10-01

Each of the antiretroviral drugs that are currently used to stop the progression of HIV infection causes its own specific side effects. Despite the expansion, multiplication, and simplification of treatment options over the past decade, side effects continue to affect people living with HIV. Yet, we see a clear disconnect between the way side effects are normalized, routinized, and framed in clinical practice and the way they are experienced by people living with HIV. This paper builds on the premise that new approaches are needed to understand side effects in a manner that is more reflective of the subjective accounts of people living with HIV. Drawing on the work of Deleuze and Guattari, it offers an original application of the theory of 'assemblage'. This theory offers a new way of theorizing side effects, and ultimately the relationship between the body and antiretroviral drugs (as technologies). Combining theory with examples derived from empirical data, we examine the multiple ways in which the body connects not only to the drugs but also to people, things, and systems. Our objective is to illustrate how this theory dares us to think differently about side effects and allows us to originally (re)think the experience of taking antiretroviral drugs. © 2016 The Authors.

Social modeling has the capacity to shape treatment outcomes, including side effects. This study investigated the influence of social modeling of treatment side effects, gender, and participant empathy, on side effects of a placebo treatment. Ninety-six participants (48 females) completed a study purportedly investigating the influence of modafinil (actually placebo) on alertness and fatigue. The participants were randomly seated with a male or female confederate and saw this confederate report experiencing side effects or no side effects. Participant empathy was assessed at baseline. Changes in modeled and general symptoms, and misattribution of symptoms, were assessed during the session and at 24-hr follow-up. During the experimental session, seeing side effect modeling significantly increased modeled symptoms (p = .023, d = 0.56) but not general or misattributed symptoms. Regardless of modeling condition, female participants seated with a female model reported significantly more general symptoms during the session. However, response to social modeling did not differ significantly by model or participant gender. At follow-up, the effect of social modeling of side effects had generalized to other symptoms, resulting in significantly higher rates of modeled symptoms (p = .023, d = 0.48), general symptoms (p = .013, d = 0.49), and misattributed symptoms (p = .022, d = 0.50). The experience of modeled symptoms in response to social modeling was predicted by participants' levels of baseline empathy. Social modeling of symptoms can increase the side effects following treatment, and this effect appears to generalize to a broader range of symptoms and symptom misattribution over time. Higher baseline empathy seems to increase response to social modeling.

Mood symptoms, such as depressed mood, anxiety and increased irritability, remain one of the major reasons for discontinuation of combined oral contraceptive (COC) pills. The aim of this study was to compare personality traits in women with ongoing or previous use of COCs and different experiences from these compounds with respect to adverse mood symptoms. Thirty women currently on COCs with no reports of adverse mood symptoms, 28 women currently on COCs and experiencing mood-related side effects, 27 women who had discontinued COC use for reasons other than adverse mood symptoms and 33 women who had discontinued COC use due to adverse mood effects were included. All participants were asked to fill out the Swedish universities Scales of Personality (SSP) to assess different personality traits. The women who were experiencing mood-related side effects on their current COC use exhibited higher scores on the somatic anxiety and stress susceptibility traits as compared to the women who did not experience any mood-related side effects from their current COCs. Women who had discontinued COC treatment because of adverse mood effects had higher scores of detachment and mistrust compared to women who had discontinued COC for reasons unrelated to mood effects. Higher scores on specific personality traits such as somatic anxiety and stress susceptibility are found in women with ongoing experience of adverse mood symptoms from COC. Higher scores of mistrust and detachment are more common among women who have discontinued COC treatment due to adverse mood effects.

LSD Flashbacks - The Appearance of New Visual Imagery Not Experienced During Initial Intoxication: Two Case Reports.

A side effect associated with the use of synthetic hallucinogens such as lysergic acid diethylamide-(LSD) is the partial or total recurrence of perceptual disturbances which previously appeared during intoxication, despite absence of recent use. These are commonly referred to as "flashbacks" or Hallucinogen Persisting Perception Disorder (HPPD). Here we present two cases of patients with a prior history of LSD use who turned to psychiatric consultation following brief episodes of HPPD. Surprisingly, in both cases new visual imagery appeared during episodes of flashbacks which was not experienced during primary LSD use. Both subjects reported the ability to discern between LSD-associated visual disturbances and new visual imagery. This phenomenon did not cause functional impairment and in both cases caused gradual concern due to its persistence. Both patients refused medical treatment and continued psychiatric follow-up. At one year follow-up both patients reported almost complete spontaneous remission. To the best of our knowledge these are the first reported cases of LSD-related benign flashbacks in which new imagery is experienced. Reasons for this reversible and apparently harmless side effect are proposed. Conclusions from case reports should be taken with caution.

Gray hair naturally develops in the process of human aging. Many people with gray hair periodically dye their hair. Hair dyeing products are widely used and they can cause adverse effects. Therefore, the user's knowledge and recognition about hair dyeing and related side effects are important. The goal of this study was to lay the foundation for understanding, preventing and treating side effects caused by hair coloring products. We conducted a questionnaire survey for adult males and females aged over 20 who had gray hair. A total of 500 subjects were included in this study and statistical analysis was performed. Large numbers of the people who had experience with hair dye (233 out of 319 people, 73.0%) did not know about the exact brand name of the hair dye product that they were using. Of 319 hair dye users, 23.8% (76 out of 319) people stated that they experienced side effects. Despite the occurrence of side effects from hair dyeing products, it seems they did not realize the seriousness of the side effects or the need for treatment. It is advisable to introduce a system that enables users to become aware of the ingredients and side effects of hair coloring products and give opportunities for users to become aware of the side effects of hair coloring through education, publicity and publication of an informational booklet.

Due to stable incidence and improved survival rates, there are an increasing number of patients living with HIV/AIDS in the USA. Although highly effective, current antiretroviral therapies are associated with a variety of side effects. The role side effects play on health outcomes has not been fully examined. The current study assessed the association of medication side effects with (1) self-assessed health status; (2) work productivity and activity impairment; and (3) healthcare resource utilization. Data were from a cross-sectional patient-reported survey fielded in the USA using a dual methodology of Internet and paper questionnaires. A total of 953 patients living with HIV/AIDS who were currently taking a medication for their condition were included in the analyses. The most frequent side effects reported by patients were fatigue (70.72%), diarrhea (62.96%), insomnia (58.97%), dizziness (52.78%), neuropathy (52.68%), joint pain (52.36%), nausea (51.63%), and abdominal pain (50.37%). The presence of each side effect was associated with reduced self-assessed health status, increased productivity loss, increased activity impairment, and increased healthcare resource use. Controlling for CD4 cell counts in regression modeling did little to diminish the impact of side effects. Although not all side effects were associated with all outcomes, every side effect was associated with worse health status, some measure of increased work productivity loss, and/or some measure of increased healthcare resource use. Patients are living longer with HIV and, therefore, spending a greater length of time on treatment. The results of the current study suggest that many of these patients are experiencing a wide array of side effects from these therapies. These side effects have demonstrated a profound association with self-assessed health, work productivity, and healthcare resource use. Improved management of these side effects or development of treatments with a better side effect profile may have a substantial humanistic and economic benefit.

Effects of buspirone on the immediate positive and delayed negative properties of intravenous cocaine as measured in the conditioned place preference test

PubMed Central

Ettenberg, Aaron; Bernardi, Rick E.

2007-01-01

In prior work, we have demonstrated that the behavioral effects of cocaine adhere to the predictions of the opponent-process theory of drug action. Animals develop conditioned place preferences for distinct locations paired with the immediate effects of IV cocaine, but learn to avoid places paired with the effects present 15-min post injection. It was of interest to assess the putative role of 5-HT in producing the negative properties of cocaine since cocaine acts to inhibit the reuptake of serotonin (5-HT) and since such actions have been associated with anxiogenic consequences. Male rats were administered a reinforcing dose of cocaine (1.0 mg/kg IV) and then placed – either immediately or after a 15-min delay -- into one side of a two-compartment (black-white) Conditioned Place Preference (CPP) box for 5-min. On alternate days, the animals received IV saline injections and were placed in the opposite side of the CPP box. This continued for eight days after which animals had experienced 4 pairings of cocaine with one side (black or white) of the CPP apparatus, and 4 saline pairings with the opposite side. Other groups of rats were treated identically except that 30-min prior to placement into the apparatus, these animals received an IP injection of saline or buspirone (a partial 5-HT1A agonist) at a dose that we have shown to be anxiolytic (2.5 mg/kg IP). Control animals experienced either buspirone or saline pretreatments without cocaine. Our results confirm that animals increase the time spent on the side paired with the immediate effects of cocaine (compared to baseline), but tend to avoid the side paired with effects present 15-min post-injection. Buspirone had no effect on the immediate rewarding properties of cocaine, but completely reversed the negative properties present 15-min post-cocaine. These results are consistent with the view that attenuation of 5-HT neurotransmission (via the autoreceptor agonist properties of buspirone) can reverse the negative impact of IV cocaine.

We identified patient and disease characteristics associated with (1) "current" physical side-effects of any severity; and (2) "severe" physical side-effects "ever" experienced by 3,348 (54%) prostate cancer (PCa) survivors in Ireland diagnosed 2-18 years previously. Postal questionnaires collected symptoms at diagnosis, post-biopsy complications, comorbidities, primary treatments and physical side-effects post-treatment (urinary incontinence, erectile dysfunction, libido loss, bowel problems, breast changes, hot flushes, and fatigue, "ever" and "current" at time of questionnaire completion). Men were grouped by "early" (localised) and "late" (locally advanced/advanced) disease at diagnosis. Multivariable logistic regression analysis identified patient and disease-related factors associated with post-treatment side-effects. Complications post-biopsy were associated with higher risk of "current" libido loss and impotence. Radical prostatectomy was associated with higher risk of "current" and "severe" incontinence, libido loss and impotence in both early and late disease. In early disease, brachytherapy was associated with lower risk of "current" fatigue and "severe" impotence. Comorbidities were associated with higher risk of "current" experience of four side-effects (incontinence, libido loss, bowel problems, fatigue). Men on active surveillance/watchful-waiting reported lower risk of sexual dysfunction. These findings could inform development of tailored information on side-effects, which, in turn, could inform treatment decision-making and post-treatment monitoring. © 2016 John Wiley & Sons Ltd.

The aim of our study was to evaluate the efficacy and safety of topical cantharidin-podophylotoxin-salicylic acid (CPS) treatment of recalcitrant plantar warts (RPW). This study was carried out in a health center in the city of A Coruña (Spain) between January and December 2013. A total of 75 patients completed all the stages of the research process. Information related to treatment with CPS and adverse effects was abstracted from medical records. Of 93 potential patients identified, 75 had at least one follow-up visit or telephone call after treatment and were included in this study. Patients experienced an average of 5.4 visits until complete resolution of their plantar wart occurred, although CPS was not applied at every visit. Fifty-four patients required one application to eliminate the wart and 21 patients required two applications/patient. Seventy-seven percent of patients experienced blistering - an expected therapeutic side effect. All patients experienced some form of an adverse event, the most common being pain (81.3%) and significant blistering (15%). Other side effects were rare (18.7%) and included pruritus, possible mild infection, significant irritation, and bleeding. All patients reported treatment, supporting our results that CPS is a safe and efficacious treatment modality for RPW and should be considered when symptomatic infection necessitates treatment. © 2016 Wiley Periodicals, Inc.

An in-office linguistic study was conducted to assess neurologist-patient discussions of epilepsy. Naturally occurring interactions among 20 neurologists and 60 of their patients with epilepsy were recorded. Participants were interviewed separately postvisit. Transcripts were analyzed using sociolinguistic techniques. Of 59 patients taking antiepileptic drugs previsit, 44 (75%) discussed side effects with their neurologist. Side effect discussions were most often neurologist initiated. Postvisit, patients and neurologists often disagreed about which side effects were experienced. The presence of a caregiver (e.g., spouse) usually resulted in lengthier, more detailed discussions of side effects, without drastically increasing overall visit length. Discussions of mood- and behavior-related comorbidities occurred infrequently (14 of 60 visits); postvisit, neurologists stated that they felt that management of these conditions was outside their area of expertise. Communication gaps observed in discussions of epilepsy and its treatment warrant further exploration. Additional research is currently underway to assess the efficacy of a previsit assessment tool.

The most common form of motorcycle collision in the UK occurs when another road user fails to give way and pulls out from a side road in front of an oncoming motorcyclist. While research has considered these collisions from the car driver's perspective, no research to date has addressed how motorcyclists approach these potential hazards. This study conducted a detailed analysis of motorcyclist speed and road position on approach to side-roads in a simulated suburban setting. Novice, Experienced and Advanced riders rode two laps of a simulated route, encountering five side-roads on each lap. On the second lap, a car emerged from the first side-road in a typical 'looked but failed to see' accident scenario. Three Experienced riders and one Novice rider collided with the hazard. The Advanced rider group adopted the safest strategy when approaching side-roads, with a lane position closer to the centre of the road and slower speeds. In contrast, Experienced riders chose faster speeds, often over the speed limit, especially when approaching junctions with good visibility. Rider behaviour at non-hazard junctions was compared between laps, to investigate if riders modified their behaviour after experiencing the hazard. Whilst all riders were generally more cautious after the hazard, the Advanced riders modified their behaviour more than the other groups after the hazard vehicle had pulled out. The results suggest that advanced training can lead to safer riding styles that are not acquired by experience alone. Copyright © 2012 Elsevier Ltd. All rights reserved.

To improve information for patients and to facilitate a vaccination coverage that is in line with the EU and World Health Organization goals, we aimed to quantify how vaccination and patient characteristics impact on influenza vaccination uptake of elderly people. An online discrete choice experiment (DCE) was conducted among 1261 representatives of the Dutch general population aged 60 years or older. In the DCE, we used influenza vaccination scenarios based on five vaccination characteristics: effectiveness, risk of severe side effects, risk of mild side effects, protection duration, and absorption time. A heteroscedastic multinomial logit model was used, taking scale and preference heterogeneity (based on 19 patient characteristics) into account. Vaccination and patient characteristics both contributed to explain influenza vaccination uptake. Assuming a base case respondent and a realistic vaccination scenario, the predicted uptake was 58%. One-way changes in vaccination characteristics and patient characteristics changed this uptake from 46% up to 61% and from 37% up to 95%, respectively. The strongest impact on vaccination uptake was whether the patient had been vaccinated last year, whether s/he had experienced vaccination side effects, and the patient's general attitude towards vaccination. Although vaccination characteristics proved to influence influenza vaccination uptake, certain patient characteristics had an even higher impact on influenza vaccination uptake. Policy makers and general practitioners can use these insights to improve their communication plans and information regarding influenza vaccination for individuals aged 60 years or older. For instance, physicians should focus more on patients who had experienced side effects due to vaccination in the past, and policy makers should tailor the standard information folder to patients who had been vaccinated last year and to patient who had not.

Jain, Aparna; Reichenbach, Laura; Ehsan, Iqbal; Rob, Ubaidur

In a country like Bangladesh that has made great progress in contraceptive use with one of the lowest levels of fertility and highest levels of contraceptive use, understanding what factors influence women's decisions to discontinue a contraceptive method and not switch to a new method is critical in designing interventions and programs that will help enable Bangladesh to reach its FP2020 goals. Research on side effects has focused on physical manifestations like headaches, moodiness, abdominal pain, and menstrual irregularities. While physical effects alone may stop women from continuing a contraceptive method, less is known about how side effects influence women's daily activities and lives. The purpose of this study is to understand the ways that side effects affect Bangladeshi women's participation in different social settings. Thirty-five in-depth interviews with married women who recently discontinued or switched to a different contraceptive method were conducted in Sylhet and Khulna Divisions. Interviews explored reasons for discontinuation including experience of side effects and impact of side effects on women's lives. Key themes emerged including that side effects are not only experienced physically but are barriers to women's participation in many aspects of their lives. The spheres of life that most commonly appeared to be influenced by side effects include religion, household, and sexual intimacy irrespective of method used or residence. Family planning providers need to be aware of these additional consequences associated with contraceptive side effects to provide tailored counseling that recognizes these issues and helps women to mitigate them. For Bangladesh to achieve its FP2020 goals, understanding the broader context in which family planning decisions are made vis-à-vis side effects is critical to design programs and interventions that meet all the needs of women beyond just their fertility intentions.

To identify the period prevalence of hormonal contraceptive (HC) use and characterise the perceived side effects associated with the menstrual cycle and HC use. 430 elite female athletes completed a questionnaire to assess; the period prevalence of HC use, the reasons for initiation and discontinuation of HCs and the side effects experienced by HC and non-HC users. Descriptive statistics, between-group comparisons and associations between categorical variables were calculated. 49.5% of athletes were currently using HCs and 69.8% had used HCs at some point. Combined oral contraceptives were most commonly used (68.1%), with 30.0% using progestin-only contraceptives (implant = 13.1%; injection = 3.7%; intrauterine system = 2.8%). Perceived negative side effects were more common with progestin-only HC use (39.1%) compared to combined HC use (17.8%; P = 0.001) and were most prevalent in implant users (53.6%; P = 0.004). HC users reported perceived positive side effects relating to the ability to predict and/or manipulate the timing, frequency and amount of menstrual bleeding. Non-HC users had a menstrual cycle length of 29 ± 5 d and 77.4% reported negative side effects during their menstrual cycle, primarily during days 1-2 of menstruation (81.6%). Approximately half of elite athletes used HCs and progestin-only contraceptive users reported greater incidences of negative side effects, especially with the implant. Due to the high inter-individual variability in reported side effects, athletes and practitioners should maintain an open dialogue to pursue the best interests of the athlete.

This study was conducted to assess the clinical efficacy and adverse effects of pilocarpine, bethanechol and cevimeline in patients with xerostomia. In this open-label crossover assessment in 20 patients with xerostomia, a one- to two-week course of each medication with a one-week washout period was prescribed. Side effects, symptoms, whole stimulated and unstimulated saliva were measured. Each sialogogue was found to increase saliva and decrease symptoms. A mixed-effects analysis showed a greater increase in stimulated saliva on bethanechol compared to pilocarpine (0.106, p = 0.0272). Increased sweating was the most common side effect, experienced more frequently with pilocarpine as compared to bethanechol (p = 0.0588) or cevimeline (p = 0.0143). A carryover effect beyond the washout period was seen. Effects on saliva and side effects vary between sialogogues, suggesting a benefit of trials with different sialogogues to determine individual patient preference. The observed carryover effect suggests that intermittent treatment may be an alternative to continuous treatment with sialogogues.

This study investigated the impact of the social modeling of side effects following placebo medication ingestion on the nocebo and placebo effect. It also investigated whether medication branding (brand or generic labeling) moderated social modeling effects. Eighty-two university students took part in the study which was purportedly investigating the impact of fast-acting beta-blocker medications (actually placebos) on preexamination anxiety. After taking the medication, participants were randomized to either witness a female confederate report experiencing side effects or no side effects after taking the same medication. Differences in symptom reporting, blood pressure, heart rate, and anxiety were assessed between the social modeling of side effects and no modeling groups. Seeing a female confederate report side effects reduced the placebo effect in systolic (p = .009) and diastolic blood pressure (p = .033). Seeing a female confederate report side effects also increased both total reported symptoms (mean [SE] 7.35 [.54] vs. 5.16 [0.53] p = .005) and symptoms attributed to the medication (5.27 [0.60] vs. 3.04 [0.59] p = .01), although the effect on symptoms was only seen in female participants. Females who saw the confederate report side effects reported approximately twice the number of symptoms as those in the no modeling group. Social modeling did not affect heart rate or anxiety. Medication branding did not influence placebo or nocebo outcomes. The social modeling of symptoms can substantially reduce or eliminate the placebo effect. Viewing a female confederate display symptoms after taking the same medication increases symptom reporting in females. (c) 2015 APA, all rights reserved).

The primary aim was to assess usability of the My Medicines and Me Questionnaire (M3Q) as a self-reported questionnaire for mental health patients to subjectively express side effects experienced with their psychotropic medications. The secondary aim was to evaluate patients' attitudes towards treatment and psychotropic medications following dialogue with their clinicians about side effects. Questionnaires were administered at six adult mental health facilities. A total of 205 participants were divided into intervention (facilitated dialogue) and non-intervention groups (no facilitated dialogue). The mean completion time for the M3Q was 15min (SD=6.5) with only 11 (5%) patients requiring assistance. The most commonly reported side effect was sedation (77%) and weight gain was ranked as the most bothersome (23%). The previously validated M3Q provided patients with the opportunity to express the impact these effects had on their lives. Side effects were the most common reason given for non-adherence. There were no significant changes in patient attitudes towards treatment and medications in the intervention group, mainly due to the logistical challenges in the clinicians' ability to view the questionnaire for the subsequent meeting with the patient. The M3Q demonstrated its usability in allowing patients to easily express their subjective experiences with side effects. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Characteristics of e-cigarette users and their perceptions of the benefits, harms and risks of e-cigarette use: survey results from a convenience sample in Ottawa, Canada.

Although e-cigarette use ("vaping") is increasing in Canada, few attempts have been made to describe e-cigarette users ("vapers"). In this context, we conducted a study in Ottawa, Canada, to describe e-cigarette users' perceptions of the benefits, harms and risks of e-cigarettes. We also collected information on why, how and where they use e-cigarettes as well as information on side effects. A 24-item online survey was administered to individuals who purchased e-cigarettes or e-cigarette-related supplies at one of Ottawa's 17 e-cigarette shops. Descriptive analyses characterized respondents, and logistic regression models were fitted to evaluate the relationship between respondents' characteristics and their perception of e-cigarette harms. The mean age of the 242 respondents was 38.1 years (range: 16-70 years); 66% were male. Nearly all had smoked 100 or more cigarettes in their lifetime (97.9%). More than 80% indicated that quitting smoking was a very important reason for starting to use e-cigarettes and 60% indicated that they intend to stop using e-cigarettes at some point. About 40% reported experiencing some side effects within 2 hours of using e-cigarettes. Those who did not report experiencing any of the listed side effects had approximately 3.2 times higher odds of perceiving e-cigarettes as harmless than those who reported having side effects (odds ratio = 3.17; 95% confidence interval: 1.75-5.73). Our findings suggest that most e-cigarette users are using them to reduce or stop smoking cigarettes and perceive them as harmless. Due to our use of convenience sampling, the reader should be cautious in generalizing our findings to all Canadian e-cigarette users.

Purpose Vemurafenib is a potent inhibitor of V600 mutant BRAF with significant impact on progression-free and overall survival in advanced melanoma. Cutaneous side effects are frequent. This single-center observational study investigates clinical and histological features of these class-specific cutaneous adverse reactions. Patients and Methods Patients were all treated with Vemurafenib 960 mg b.i.d. within local ethic committees approved clinical trials. All skin reactions were collected and documented prospectively. Cutaneous reactions were classified by reaction pattern as phototoxic and inflammatory, hair and nail changes, keratinocytic proliferations and melanocytic disorders. Results Vemurafenib was well tolerated, only in two patients the dose had to be reduced to 720 mg due to arthralgia. 26/28 patients (93%) experienced cutaneous side effects. Observed side effects included UVA dependent photosensitivity (n = 16), maculopapular exanthema (n = 14), pruritus (n = 8), folliculitis (n = 5), burning feet (n = 3), hair thinning (mild alopecia) (n = 8), curly hair (n = 2) and nail changes (n = 2). Keratosis pilaris and acanthopapilloma were common skin reactions (n = 12/n = 13), as well as plantar hyperkeratosis (n = 4), keratoacanthoma (n = 5) and invasive squamous cell carcinoma (n = 4). One patient developed a second primary melanoma after more than 4 months of therapy (BRAF and RAS wild type). Conclusion Vemurafenib has a broad and peculiar cutaneous side effect profile involving epidermis and adnexa overlapping with the cutaneous manifestations of genetic diseases characterized by activating germ line mutations of RAS (RASopathy). They must be distinguished from allergic drug reaction. Regular skin examination and management by experienced dermatologists as well as continuous prophylactic photo protection including an UVA optimized sun screen is mandatory. PMID:23516541

Menopausal Symptom Relief and Side Effects Experienced by Women Using Bioidentical Hormone Replacement Therapy and Synthetic Conjugated Equine Estrogen and/or Progestin Hormone Replacement Therapy, Part 1.

Deleruyelle, Laura J

2016-01-01

The use of compounded bioidentical hormone replacement therapy by menopausal women has become a popular alternative to traditional synthetic conjugated equine estrogen and progestin hormone replacement therapy due to safety concerns raised by recent studies. However, due to the lack of randomized, large-scale trials to evaluate the efficacy and side-effect profile of compounded bioidentical hormone replacement therapy many healthcare providers are reluctant to prescribe such therapy. The purpose of this study was to compare women's menopausal symptom relief and side effects experienced when using compounded bioidentical hormone replacement therapy and traditional hormone replacement therapy. A descriptive comparative design was used. Inferential and descriptive statistical procedures including a paired difference t -test, two-sample t -test, and f tests (percentage, mean, standard deviation, frequency) were run on the Statistical Package for the Social Sciences. The framework used to guide this study was Lenz and Pugh's Theory of Unpleasant Symptoms. Surveys were distributed once to a convenient sample of women aged 35 and older when they dropped off or picked up their prescriptions at a pharmacy. Of the 216 surveys distributed, 70 were returned from those women taking compounded bioidentical hormone replacement therapy and 53 from traditional hormone replacement therapy. The survey contained 15 questions pertaining to age, duration of hormone replacement therapy, type and formulation of hormone replacement therapy, reasons for initiating hormone replacement therapy, symptoms before and one month after hormone replacement therapy, and side effects related to hormone replacement therapy. The results of this study will be summarized in forthcoming articles in this series. Copyright© by International Journal of Pharmaceutical Compounding, Inc.

Despite the demonstrated benefits of influenza vaccinations, the coverage is lower than expected among health-care personnel (HCP). In this study we surveyed the attitudes of pediatric residents regarding influenza immunization and adverse reactions. Forty-five female and 35 male pediatric residents with ages ranging from 24 to 28 years were vaccinated with an influenza vaccine on 2 days in the 3rd week of September 2005 by the same nurse. Among our resident, 27 (33.7%) thought the vaccine unnecessary; their vaccine coverage was only 12% in the previous year. Thirteen residents (16%) had soreness at the vaccination site; 7 (8%) had other local reactions that did not interfere with everyday activities, and 16 (20%) had any systemic side effects. The overall rate of side effects from the vaccination was 36.5% (n=29). Twenty of the 29 vaccinees who experienced side effects stated they did not want to receive the vaccine the following year because of the side effects, while 13% in the group without side effects stated the same thing, mainly because of the cost of vaccination. We would like to recommend an influenza vaccination campaign for HCP by employers, but first we must plan to take steps to improve the acceptability of the influenza vaccine among HCP.

Three patients with a DSM-III-R diagnosis of posttraumatic stress disorder were successfully treated with buspirone in final maximum dosages ranging from 35-60 mg daily. The onset of clinical efficacy ranged from 5-29 days. Symptoms that improved included anxiety, insomnia, flashbacks, and depressed mood. Patients experienced no side effects. Serotonin partial agonist effects are a possible mechanism underlying buspirone's efficacy.

Objective To assess experiences related to antidepressant use reported to an internet-based medicine reporting system and to compare the nature of the side effects reported by patients with those reported by health care professionals (HCPs). Methods All reports submitted from May 2004 to May 2005 to an internet-based medicine reporting system in The Netherlands related to the use of antidepressants were analysed. Spontaneous reports of adverse drug reactions on antidepressants from HCPs received by The Netherlands Pharmacovigilance Centre Lareb from May 2004 to May 2005 were included for comparison. Results Of the 2232 individuals who submitted a report to the internet-based medicine reporting system, 258 submitted a report on antidepressants. Of these, 92 individuals (36%) reported on effectiveness, 40 (16%) of whom reported on ineffectiveness, and 217 (84%) submitted a report on side effects, with 202 (78%) reporting a total of 630 side effects that were experienced as negative. Fourteen individuals (5%) reported a practical issue and four (2%) reported a reimbursement issue. Of all 630 side effects reported, 48% resulted in the patient discontinuing the antidepressant therapy; of these 29% did not inform their HCP. Of all the side effects reported, 52% were perceived as “very negative”. In comparison to the side effects reported by HCPs, patients more often reported apathy, excessive sweating, ineffectiveness, somnolence, insomnia, sexual problems and weight increase. Conclusion Patients report the ineffectiveness and side effects of antidepressant therapy as negative and leading to discontinuation of the therapy. Patients and HCPs differ in the nature of the reported side effects. Patient experiences should be included in the evaluation of antidepressant treatment in clinical practice. PMID:17874086

Systemic and intrathecal methotrexate is widely used in treatment protocols for childhood acute lymphoblastic leukemia. Its side effects vary in characteristics, intensity and time of onset, and depend on the administration route. Interactions with several drugs are known. Side effects of nitrous oxide sedation, often used for moderately painful procedures, typically occur after long time use and include neurological symptoms. We present a child who experienced a severe and long-lasting neurotoxicity after the third intrathecal application of methotrexate with short sedation by nitrous oxide during induction therapy for acute lymphoblastic leukemia.

Many methods, which have effectively reduced the number of patients requiring hospital admission, have been described for the outpatient treatment of hemorrhoids. However, complications have been reported, and the methods are often associated with unpleasant side effects. In 1977 Neiger et al. described a new method that used infrared coagulation, which produced minimal side effects. The authors have conducted a prospective, randomized trial to evaluate infrared coagulation compared with more traditional methods of treatment. The authors' results show that it may be more effective than injection sclerotherapy in treating non-prolapsing hemorrhoids and that it compares favorably with rubber band ligationmore » in most prolapsing hemorrhoids. No complications occurred, and significantly fewer patients experienced pain after infrared coagulation (P . less than 0.001).« less

Patterns of benzylpiperazine/trifluoromethylphenylpiperazine party pill use and adverse effects in a population sample in New Zealand.

A large legal market for party pills containing benzylpiperazine (BZP) and trifluoromethylphenylpiperazine (TFMPP) developed in New Zealand after 2004. The use of these party pills has been associated with adverse health effects. The purpose of this paper was to assess a general population sample of party pill users to investigate the relationship between (1) patterns of use of BZP/TFMPP party pills and concurrent use of other drug types, and (2) adverse side effects from BZP/TFMPP party pill use. A national household survey of the use of BZP/TFMPP party pills was conducted using a computer-assisted telephone interviewing (CATI) facility. The quantity of BZP and TFMPP in each brand of party pill was obtained from the National Poisons Centre. Multiple logistic regression analysis was used to identify independent predictors of having experienced adverse side effects from party pills. The mean quantity of BZP/TFMPP taken on an occasion of greatest use was 533 mg (median 400 mg, range 43-2500 mg). Being female, using cannabis and other drugs concurrently with BZP/TFMPP party pills, taking large quantities of party pills in a single session and taking 5-hydroxytryptophan (5-HTP) recovery pills at the same time as party pills were independent predictors of having experienced an adverse problem from party pills. Females may be at greater risk of experiencing problems from BZP/TFMPP party pills due to their smaller physical size. Taking 5-HTP 'recovery' pills with party pills may increase the risk of adverse effects as both substances increase users' levels of serotonin.

2003-01-01

Using a matched case control design, this study measured the mortality associated with paired passenger car-sport utility vehicle side impact (‘T-bone’) collisions using FARS data. Survival versus fatal outcome within the matched crash pairs was measured with matched pair odds ratios. Conditional logistic regression adjusted for multiple effects. Overall, passenger car drivers experienced greater mortality than did SUV drivers, regardless if they were in the struck or striking vehicle (odds ratio: 10.0; 95% confidence interval: 7.9, 12.5). Differential mortality persisted after adjustment for confounders. Efforts should be sought to improve passenger car side impact crashworthiness and to reduce SUV aggressivity. PMID:12941243

To assess the benefit of adjunctive use of a SPF 30 moisturizing lotion in reducing local side effects associated with atopical tretinoin cream. This was a randomized, investigator/evaluator-blinded, split-face comparison in subjects with healthy skin. Subjects applied tretinoin cream 0.05% once daily to the whole face and Cetaphil 174; Dermacontrol Moisturizer (CDM) once daily to one side of the face based on randomization. Tolerability, perference and skin hydration were evaluated at each week, and a cosmetic acceptability questionnaire regarding CDM was completed at the end of the study. The majority (about 83% to 86%) of subjects experienced skin irritations on both sides of their face, though predominantly mild for the CDM + tretinoin treated side. Tolerability preferences favored the CDM+tretinoin sides. Adjunctive use of CDM with a topical tretinoin cream improves tolerance of the treatment.

A total of 136 dentulous patients were divided into three groups for purposes of quantitative pantographic comparison of voluntary and induced Bennett movement. The effects of patient age and operator experience on recording the Bennett movement were also studied. The results indicates that for patients studied with Bennett movement iduced in the manner described: 1. Experienced operators can obtain more induced Bennett movement that inexperienced operators. 2. Inducing Bennett movement has a greater effect on the immediate side shift component than it has on the progressive side shift component. 3. For older individuals the amount and direction of induced immediate side shift is greater than for younger patients, statistically highly significant, and therefore clinically important. In conclusion, if the objective of a pantographic survey is to record the complete capacity of the joint to move, *lateral jaw movements must be induced.

Cho, Bo-Keun; Aghazadeh, Fereydoun; Al-Qaisi, Saif

2012-01-01

The purpose of this study was to determine the effects of video-game experience and flight-stick position on flying performance. The study divided participants into 2 groups; center- and side-stick groups, which were further divided into high and low level of video-game experience subgroups. The experiment consisted of 7 sessions of simulated flying, and in the last session, the flight stick controller was switched to the other position. Flight performance was measured in terms of the deviation of heading, altitude, and airspeed from their respective requirements. Participants with high experience in video games performed significantly better (p < .001) than the low-experienced group. Also, participants performed significantly better (p < .001) with the center-stick than the side-stick. When the side-stick controller was switched to the center-stick position, performance scores continued to increase (0.78 %). However, after switching from a center- to a side-stick controller, performance scores decreased (4.8%).

Why offspring in nonhuman families differ.

PubMed

Forbes, Scott

2013-07-18

Offspring within families, both human and nonhuman, often differ. The obvious question is: Why? Work on psychological differences on children within human families has focused primarily on differences in the nonshared environment of contemporary siblings, though the precise location of this nonshared environment is still the subject of much debate. Here I explore the range of explanations for within-brood diversity from the perspective of nonhuman families, particularly birds that share certain key features with human families. I examine the role of social rank in creating a nonshared environment within the family, and present data from a model system (an altricial bird) to illustrate how different the effective environments experienced by offspring sitting side-by-side in the same confined physical space, tended by the same parents, and experiencing similar ecological variability, can be. These broodmates can effectively live in different worlds. I then briefly explore other sources of diversity among offspring in nonhuman families, including within brood genetic differences and non-genetic maternal (parental) effects that often covary with birth / hatching rank. Given the ubiquity and far-reaching consequences of maternal effects in nonhuman families, and some human data suggestive of similar patterns, it would seem worthwhile to explore the potential role of maternal effects in creating phenotypic diversity in psychological traits among children in human families.

Atenolol versus pindolol: side-effects in hypertension.

PubMed

Foerster, E C; Greminger, P; Siegenthaler, W; Vetter, H; Vetter, W

1985-01-01

This randomized crossover out-patient study was designed to compare the antihypertensive effects of atenolol and pindolol. After a wash-out period of two weeks in pretreated cases, 107 patients with essential hypertension were given either atenolol 100 mg once-daily or pindolol 20 mg slow release (SR) once-daily. Both atenolol and pindolol lowered blood pressure over the 24 week period. The diastolic blood pressure reduction was significantly greater (p less than 0.01) with atenolol than with pindolol. Before beta-blocker therapy, many patients had already experienced side-effects such as fatigue, sleep disturbances and dreams. This probably relates to the high sensitivity of the analogue scale used to assess side-effects, and to the high incidence of such symptoms in untreated patients. As the study progressed there was a reduction in the frequency of fatigue (p less than 0.03) and dreams (p less than 0.05) in both groups, whereas sleep disturbances significantly increased under pindolol (p less than 0.05) but decreased under atenolol (p less than 0.05). The only important side-effect difference between the two beta-blockers was the higher incidence of sleep disturbances with pindolol which may be due to the higher lipophilicity of this beta-blocker.

Antipsychotic medications often have a variety of side effects, however, it is not well understood how the presence of specific side effects correlate with adherence in a real-world setting. The aim of the current study was to examine the relationship between these variables among community-dwelling patients with schizophrenia. Data were analyzed from a 2007-2008 nationwide survey of adults who self-reported a diagnosis of schizophrenia and were currently using an antipsychotic medication (N = 876). The presence of side effects was defined as those in which the patient reported they were at least "somewhat bothered". Adherence was defined as a score of zero on the Morisky Medication Adherence Scale. To assess the relationship between side effects and adherence, individual logistic regression models were fitted for each side effect controlling for patient characteristics. A single logistic regression model assessed the relationship between side effect clusters and adherence. The relationships between adherence and health resource use were also examined. A majority of patients reported experiencing at least one side effect due to their medication (86.19%). Only 42.5% reported complete adherence. Most side effects were associated with a significantly reduced likelihood of adherence. When grouped as side effect clusters in a single model, extra pyramidal symptoms (EPS)/agitation (odds ratio (OR) = 0.57, p = 0.0007), sedation/cognition (OR = 0.70, p = 0.033), prolactin/endocrine (OR = 0.69, p = 0.0342), and metabolic side effects (OR = 0.64, p = 0.0079) were all significantly related with lower rates of adherence. Those who reported complete adherence to their medication were significantly less likely to report a hospitalization for a mental health reason (OR = 0.51, p = 0.0006), a hospitalization for a non-mental health reason (OR = 0.43, p = 0.0002), and an emergency room (ER) visit for a mental health reason (OR = 0.60, p = 0.008). Among patients with schizophrenia, medication side effects are highly prevalent and significantly associated with medication nonadherence. Nonadherence is significantly associated with increased healthcare resource use. Prevention, identification, and effective management of medication-induced side effects are important to maximize adherence and reduce health resource use in schizophrenia.

To explore the nature and severity of side effects and future preference of intradermal versus intramuscular influenza vaccination in healthcare workers. Prospective cohort study. Two University Medical Centers in The Netherlands. Healthcare workers receiving an influenza vaccination. Healthcare workers that were vaccinated during the influenza vaccination season of 2012-2013 were approached for participation in a questionnaire study. The questionnaire was divided into two parts. The first part had to be answered directly after vaccination and the second part two weeks after vaccination. The motivation for vaccine uptake, whether or not the HCWs had direct contact with patients and the prevalence and severity of local and systemic side effects of influenza vaccination were explored. In addition, it was assessed how participants experienced the vaccination and which type of administration they preferred for future vaccination. Side effects of vaccination were more prevalent in the intradermal group versus the intramuscular group (56% versus 26%, p<0.001). Local side effects were perceived as more severe in healthcare workers receiving the intradermal vaccine. Directly after vaccination, healthcare workers preferred the intradermal vaccination. Two weeks after vaccination both types of vaccine were equally appreciated. This study shows that there are significant differences in the nature and severity of side effects upon intramuscular and intradermal influenza vaccination. This difference did not result in a preference among the vaccinated subjects for one type of vaccine. Copyright © 2017 Elsevier Ltd. All rights reserved.

Borghi, Alessandro; Corazza, Monica; Minghetti, Sara; Virgili, Annarosa

2015-01-01

To assess the effectiveness and safety of a 24-week application of tretinoin 0.025% cream, with an alternate-day regimen, in achieving control of VLS signs and symptoms. 17 patients affected with VLS were included. The main efficacy parameters were the response rate, as defined by protocol parameters, the rate of patients achieving an improvement from baseline of ≥75% in the subjective and objective scores, and the mean reduction in subjective and objective scores throughout the treatment. The safety of the treatment was also assessed. By the end of the 24-week treatment, 12 patients (70.6%) experienced a response; 35.3% and 17.6% of patients achieved an improvement of at least 75% in subjective and objective scores, respectively. Mean scores of itching, leukoderma (pallor) and hyperkeratosis decreased significantly in the study patients, and none presented itching-related excoriations. Erythema increased compared with baseline. Six patients (35.29%) experienced some side effects related to tretinoin, mainly mild erythema and burning. None of the subjects discontinued the treatment because of side effects. Tretinoin 0.025% cream applied for 24 weeks may represent a useful alternative option to corticosteroids in the treatment of active VLS, acting particularly on hyperkeratosis and pallor.

An audit of the use of intra-septal local anaesthesia in a dental practice in the South of England.

The aim of this audit was to evaluate the efficacy, when used by the author, of the intra-septal local anaesthetic technique for cavity preparation in mandibular molar and premolar teeth. One hundred and thirteen consecutive patients who required local anaesthesia (LA) for cavity preparation in lower molar and premolar teeth in a general dental practice took part in the audit sample. Articaine 4%, with 1:100,000 adrenaline (epinephrine), was administered using the intra-septal technique. Visual analogue scales (VAS) were used to record pain experienced on injection and the quality of anaesthesia obtained. Any side-effects reported were recorded. The standards set were that at least 70% should find the administration of the LA pain-free and that at least 80% should experience no pain during cavity preparation. Sixty-nine (62%) patients reported the injection technique to be completely pain-free and a further 23 (20%) reported very minor pain on injection. Eighty (71%) patients reported pain-free treatment and 18 (16%) experienced very minor pain during treatment. No side-effects were reported. Patients aged under 40 years and those who had cavities prepared in first premolar teeth appeared more likely to experience pain during cavity preparation. The intra-septal injection technique requires no specialist equipment, is easily administered, rapid in onset and provides a level of anaesthesia equivalent to that produced by an inferior dental nerve block and with fewer side-effects. The injection is relatively painless to administer.

Although dexamethasone is an effective treatment for acute lymphoblastic leukemia (ALL), it can induce a variety of serious neurobehavioral side effects. We hypothesized that these side effects are influenced by glucocorticoid sensitivity at the tissue level. We therefore prospectively studied whether we could predict the occurrence of these side effects using the very low-dose dexamethasone suppression test (DST) or by measuring trough levels of dexamethasone. Fifty pediatric patients (3-16 years of age) with acute lymphoblastic leukemia (ALL) were initially included during the maintenance phase (with dexamethasone) of the Dutch ALL treatment protocol. As a marker of glucocorticoid sensitivity, the salivary very low-dose DST was used. A post-dexamethasone cortisol level <2.0nmol/L was considered a hypersensitive response. The neurobehavioral endpoints consisted of questionnaires regarding psychosocial and sleeping problems administered before and during the course of dexamethasone (6mg/m(2)), and dexamethasone trough levels were measured during dexamethasone treatment. Patients with a hypersensitive response to dexamethasone had more behavioral problems (N=11), sleeping problems, and/or somnolence (N=12) (P<0.05 for all three endpoints). The positive predictive values of the DST for psychosocial problems and sleeping problems were 50% and 30%, respectively. Dexamethasone levels were not associated with neurobehavioral side effects. We conclude that neither the very low-dose DST nor measuring dexamethasone trough levels can accurately predict dexamethasone-induced neurobehavioral side effects. However, patients with glucocorticoid hypersensitivity experienced significantly more symptoms associated with dexamethasone-induced depression. Future studies should elucidate further the mechanisms by which neurobehavioral side effects are influenced by glucocorticoid sensitivity. Copyright © 2016 Elsevier Ltd. All rights reserved.

Background and study aims: Endoscopic submucosal dissection (ESD) using insulation-tipped knives (IT knives) to treat gastric lesions located on the greater curvature of the gastric body remains technically challenging because of the associated bleeding, control of which can be difficult and time consuming. To eliminate these difficulties, we developed a novel strategy which we have called the “near-side approach method” and assessed its utility. Patients and methods: We reviewed patients who underwent ESD for solitary early gastric cancer located on the greater curvature of the gastric body from January 2003 to September 2014. The technical results of ESD were compared between the group treated with the novel near-side approach method and the group treated with the conventional method. Results: This study included 238 patients with 238 lesions, 118 of which were removed using the near-side approach method and 120 of which were removed using the conventional method. The median procedure time was 92 minutes for the near-side approach method and 120 minutes for the conventional method. The procedure time was significantly shorter in the near-side approach method arm. Although, the procedure time required by an experienced endoscopist was not significantly different between the two groups (100 vs. 110 minutes), the near-side approach group showed significantly shorter procedure time for a less-experienced endoscopist (90 vs. 120 minutes). Conclusions: The near-side approach method appears to require less time to complete gastric ESD than the conventional method using IT knives for technically challenging lesions located on the greater curvature of the gastric body, especially if the procedure is performed by less-experienced endoscopists.

Mining Archived HYSPEC User Data to Analyze the Prompt Pulse at the SNS

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

Smith, Michael B.; Iverson, Erik B.; Gallmeier, Franz X.

The Hybrid-Spectrometer (HYSPEC) is one of 17 instruments currently operated at the Spallation Neutron Source (SNS) at Oak Ridge National Laboratories (ORNL). The secondary spectrometer of this instrument is located inside an out-building off the north side of the SNS instrument hall. HYSPEC has experienced a larger background feature than similar inelastic instruments since its commissioning in 2011. This background feature is caused by a phenomenon known as the “prompt pulse” which is an essential part of neutron production in a pulsed spallation source but comes with unfortunate side effects.

Objective: The aim of this study was to investigate the relationship between patient characteristics and adenosine-related side-effects during stress myocard perfusion imaging (MPI). The effect of presence of adenosine-related side-effects on the diagnostic value of MPI with integrated SPECT/CT system for coronary artery disease (CAD), was also assessed in this study. Methods: Total of 281 patients (109 M, 172 F; mean age:62.6±10) who underwent standard adenosine stress protocol for MPI, were included in this study. All symptoms during adenosine infusion were scored according to the severity and duration. For the estimation of diagnostic value of adenosine MPI with integrated SPECT/CT system, coronary angiography (CAG) or clinical follow-up were used as gold standard. Results: Total of 173 patients (61.6%) experienced adenosine-related side-effects (group 1); flushing, dyspnea, and chest pain were the most common. Other 108 patients completed pharmacologic stress (PS) test without any side-effects (group 2). Test tolerability were similar in the patients with cardiovascular or airway disease to others, however dyspnea were observed significantly more common in patients with mild airway disease. Body mass index (BMI) ≥30 kg/m2 and age ≤45 years were independent predictors of side-effects. The diagnostic value of MPI was similar in both groups. Sensitivity of adenosine MPI SPECT/CT was calculated to be 86%, specificity was 94% and diagnostic accuracy was 92% for diagnosis of CAD. Conclusion: Adenosine MPI is a feasible and well tolerated method in patients who are not suitable for exercise stress test as well as patients with cardiopulmonary disease. However age ≤45 years and BMI ≥30 kg/m2 are the positive predictors of adenosine-related side-effects, the diagnostic value of adenosine MPI SPECT/CT is not affected by the presence of adenosine related side-effects.

Opioids cause gastrointestinal (GI) symptoms such as nausea, vomiting, pain, and (in 40 percent) constipation that diminish patients' quality of life. Outside traditional surveys, little is known about the opioid-induced constipation (OIC) patient experience and its impact on pain management. The purpose of this study was to use data from social media platforms to qualitatively examine patient beliefs about OIC and other prominent GI side effects, their impact on effective pain management and doctor-patient interaction. The authors collected Tweets from March 25 to July 31, 2014, and e-forum posts from health-related social networking sites regardless of timestamp. The authors identified specific keywords related to opioids and GI side effects to locate relevant content in the dataset, which was then manually coded using ATLAS.ti software. The authors examined 2,519,868 Tweets and more than 1.8 billion e-forum posts, of which, 88,586 Tweets and 9,767 posts satisfied the search criteria. Three thousand three individuals experienced opioidinduced GI side effects, mostly related to phenanthrenes (n = 1,589), and 1,274 (42.4 percent) individuals described constipation. Over-the-counter medications and nonevidence-based natural approaches were most commonly used to alleviate constipation. Many individuals questioned, rotated, reduced, or stopped their opioid treatments as a result of their GI side effects. Investigation of social media reveals a struggle to balance pain management with opioid-induced GI side effects, especially constipation. Individuals are often unprepared to treat OIC, to modify opioid regiments without medical advice, and to resort to using natural remedies and treatments lacking scientific evidence of effectiveness. These results identify opportunities to improve physician-patient communication and explore effective treatment alternatives.

To determine the incidence of acute side effects of three commonly used gadolinium contrast agents in the paediatric population. A retrospective review of medical records was performed to determine the incidence of acute adverse side effects of i.v. gadolinium contrast agents [MultiHance(®) (Bracco Diagnostics Inc., Princeton, NJ), Magnevist(®) (Bayer Healthcare Pharmaceuticals, Wayne, NJ) or Gadavist(®) (Bayer HealthCare Pharmaceuticals)] in paediatric patients. 40 of the 2393 patients who received gadolinium contrast agents experienced acute side effects, representing an incidence of 1.7%. The majority of the acute side effects (in 30 patients) were nausea and vomiting. The incidence was significantly higher in non-sedated patients (2.37% vs 0.7%; p = 0.0018). Furthermore, without sedation, the incidence of both nausea and vomiting was significantly higher in children receiving MultiHance, with a 4.48% incidence of nausea when compared with Magnevist (0.33%, p < 0.0001) and Gadavist (0.28%, p < 0.0001) and a 2.36% incidence of vomiting compared with those for Magnevist (0.50%, p = 0.0054) and Gadavist (0.28%, p = 0.014), whereas no difference was observed between Magnevist and Gadavist within the power of the study. In addition, there was no apparent difference between any of the three contrast agents for the incidence of allergy or other acute side effects detected, given the sample size. The gadolinium contrast agents MultiHance, Magnevist and Gadavist have a low incidence of acute side effects in the paediatric population, a rate that is further reduced in moderately sedated patients. MultiHance demonstrated significantly increased incidence of gastrointestinal symptoms compared with Magnevist and Gadavist. The incidence of acute side effects of three commonly used gadolinium contrast agents was determined in the paediatric population, which can have clinical implications.

The influence of personal message with music on anxiety and side effects associated with chemotherapy.

PubMed

Sabo, C E; Michael, S R

1996-08-01

The purpose of this pilot study was to evaluate the benefits of a message from a patient's physician audiotaped over music on reducing anxiety and side effects of patients receiving chemotherapy. A convenience sample of 97 adult patients receiving chemotherapy for the first time was assigned to either an experimental or control group. Before beginning the first chemotherapy treatment, all subjects completed a demographic questionnaire and the Spielberger State Anxiety Inventory (SSAI). Participants in the experimental group (n = 47) received taped music and a message from their physicians during the next four chemotherapy treatments. Participants in the control group (n = 50) received no intervention from the researchers and underwent their next four chemotherapy treatments as prescribed. After the fourth chemotherapy treatment, the SSAI and a side-effects self-assessment evaluation were completed by all subjects. A paired one-tailed t test found a significant difference between pre- and postintervention scores on the state anxiety scale (p < 0.001). In addition, anxiety remained the same over time in the control group. There was no significant difference in the severity of side effects experienced between control and experimental groups. These preliminary findings indicate that a simple and cost-effective intervention can decrease a patient's anxiety when receiving chemotherapy.

Efficacy of electroconvulsive therapy (ECT) and duration of associated side effects is uncertain. We wanted to study indications, efficacy, time to response and side effects. ECT-protocols and medical records (from the period 1960-95) in three psychiatric wards of Dikemark Mental Hospital, Norway were systematically assessed. 141 persons underwent 241 ECT series comprising 1960 treatment sessions. Major depressive disorder was the main diagnosis in most patients 124 [88 %]. Before ECT, 129 (91 %) patients had been treated with at least one antidepressant, 107 (76 %) with at least two and 67 (48 %) with two different classes of antidepressants without sufficient clinical recovery from the incident. 31 (22 %) had received lithium before ECT. Within four weeks after the first ECT, 120 (85 %) patients had recovered. 61 of these achieved remission and were discharged within four weeks. After the first ECT series, 92 patients showed signs of improvement. 71 (77 %) had signs of improvement within 6 days. Side effects were noted after 123 of totally 241 series (51 %). Five patients experienced serious complications. Interpretation. The immediate effect of ECT was good and signs of recovery were observed in most patients during the first week. Depressed psychotic patients and the elderly seemed to respond best. Considering these patients' serious and long-lasting disorders ECT was fairly safe and well tolerated.

To compare honey and IntraSite Gel as woundhealing agents, to record side-effects, gauge patient satisfaction and calculate the cost-effectiveness of the honey used. A prospective, randomised, double-blind controlled trial was carried out among goldmine workers. Outcome measures were healing times of shallow wounds and abrasions; side-effects; patient satisfaction with treatment; and amount of honey and IntraSite Gel used. The mean healing times of shallow wounds treated with honey or with IntraSite Gel did not differ significantly (p = 0.75, 95% confidence interval (CI): -5.41; 7.49 days). When adjusted for wound size, the 2.8-day difference in favour of honey was not significant (p = 0.21, 95% CI: -2.41; 8.09). In the case of abrasions there was also no significant difference (p = 0.83, 95% CI: -4.98; 6.19 days). When adjusted for wound size, the difference of 0.22 days in favour of IntraSite Gel was not significant (p = 0.94, 95% CI: -5.72; 6.15.4). Of patients treated with honey, 27% and 10% respectively experienced itching and pain, and 2 experienced burning for a short time after application. Of patients treated with IntraSite Gel, 31% experienced itching. All patients in both treatment groups were either satisfied or extremely satisfied with treatment. The average cost of treatment per patient was R0.49 with honey and R12.03 with with IntraSite Gel. A distinction should be made between shallow wounds and abrasions when wound healing is being measured. There was no evidence of a real difference between honey and IntraSite Gel as healing agents. Honey is a safe, satisfying and effective healing agent. Natural honey is extremely costeffective.

The risks and benefits of switching patients with schizophrenia or schizoaffective disorder from two to one antipsychotic medication: a randomized controlled trial.

PubMed

Constantine, Robert J; Andel, Ross; McPherson, Marie; Tandon, Rajiv

2015-08-01

Despite little evidence to support its use and practice guidelines discouraging the practice, antipsychotic polypharmacy is widely prevalent in schizophrenia. This randomized controlled trial studied the effects of switching patients stable on two antipsychotic medications to one antipsychotic medication. 104 adult outpatients with schizophrenia from 7 community mental health centers clinically stable on concurrent treatment with 2 antipsychotics were randomly assigned to stay on polypharmacy or to switch to antipsychotic monotherapy. Participants were followed for 1-year with assessments of symptoms and side effects occurring every 60days (7 total assessments). We examined differences in time trajectories in symptoms (PANSS, CGI) and side effects (EPS, metabolic, other) as a function of group assignment (switch vs. stay) and time, using intention-to-treat analysis. Participants who switched to antipsychotic monotherapy experienced greater increases in symptoms than stay patients. These differences emerged in the second 6months of the trial. All-cause discontinuation rates over the 1-year trial were higher in the switch-to-monotherapy group than in the stay-on-polypharmacy group (42% vs. 13%; p<0.01). There were no differences in change over time in any of the side effect measures, except that stay patients experienced a greater decrease in Simpson Angus total scores than switch patients. Clinicians should be cautious in switching patients with chronic schizophrenia who are stable on 2 antipsychotics to one antipsychotic. Given the challenges in discontinuing antipsychotic polypharmacy, adequate trials of evidence-based treatments such as clozapine and long-acting injectable antipsychotics should be undertaken in inadequately responsive schizophrenia patients before moving to antipsychotic polypharmacy.

Methotrexate is associated with neurologic side effects. It is recommended that patients who developed neurotoxicity be rechallenged with methotrexate, but little is known about the safety of this approach. We performed a chart review to identify patients who received high-dose or intrathecal (IT) methotrexate. Twenty-one of 298 patients (7%) experienced neurologic symptoms attributed to methotrexate treatment in the premaintenance phase. Seventeen of these patients were rechallenged with IT methotrexate and 13 (76%) had no further neurotoxic events. No patients rechallenged during maintenance (n = 9) experienced recurrence of neurotoxic events. It is safe to rechallenge with IT methotrexate in maintenance. © 2015 Wiley Periodicals, Inc.

Fatigue is a prevalent source of suffering in children with advanced cancer; yet, little is known about it. This study aimed to describe fatigue experienced by children with advanced cancer and to identify the factors associated with suffering from fatigue and its treatment. A retrospective cross-sectional study of 141 parents of children who died of cancer (response rate: 64%) was conducted in two tertiary-level U.S. pediatric hospitals. By parent report, 96% of children experienced fatigue in the last month of life. Nearly 50% experienced significant suffering from fatigue; this was associated with suffering from pain, dyspnea, anorexia, nausea/vomiting, diarrhea, anxiety, sadness, or fear (P<0.05), and with side effects from pain or dyspnea treatment (P<0.05). In multivariate analysis of symptom-related factors, suffering from nausea/vomiting (odds ratio [OR]=3.93, 95% confidence interval [CI]=1.23-12.61, P=0.02); anorexia (OR=7.52, 95% CI=1.87-30.25, P=0.005); and fear (OR=5.13, 95% CI=2.03-12.96, P ≤ 0.001) remained independently associated with fatigue. Children suffering from fatigue had primary oncologists with fewer years' experience than children who did not suffer from fatigue (mean=7.7 years, standard deviation [SD]=4.9 vs. mean of 9.9 years, SD=6.0, P=0.02). Among children with fatigue, 17 of 129 (13%) received fatigue-directed treatment, which was successful in 3 of 12 (25%). Children experiencing side effects from dyspnea or pain treatment were more likely to be treated for fatigue (relative risk=1.25, 95% CI=1.06-1.47, P=0.009). Fatigue is a common source of suffering in children with cancer at the end of life. Palliation of this symptom is rarely successful. Increased attention to factors associated with fatigue and effective interventions to ameliorate fatigue are needed. Copyright © 2010 U.S. Cancer Pain Relief Committee. Published by Elsevier Inc.

EXERCISE IMPROVES SEXUAL FUNCTION IN WOMEN TAKING ANTIDEPRESSANTS: RESULTS FROM A RANDOMIZED CROSSOVER TRIAL

PubMed Central

Lorenz, Tierney Ahrold; Meston, Cindy May

2014-01-01

Background In laboratory studies, exercise immediately before sexual stimuli improved sexual arousal of women taking antidepressants [1]. We evaluated if exercise improves sexual desire, orgasm, and global sexual functioning in women experiencing antidepressant-induced sexual side effects. Methods Fifty-two women who were reporting antidepressant sexual side effects were followed for 3 weeks of sexual activity only. They were randomized to complete either three weeks of exercise immediately before sexual activity (3×/week) or 3 weeks of exercise separate from sexual activity (3×/week). At the end of the first exercise arm, participants crossed to the other. We measured sexual functioning, sexual satisfaction, depression, and physical health. Results Exercise immediately prior to sexual activity significantly improved sexual desire and, for women with sexual dysfunction at baseline, global sexual function. Scheduling regular sexual activity significantly improved orgasm function; exercise did not increase this benefit. Neither regular sexual activity nor exercise significantly changed sexual satisfaction. Conclusions Scheduling regular sexual activity and exercise may be an effective tool for the behavioral management of sexual side effects of antidepressants. PMID:24754044

Cancer-related fatigue, insomnia, and cancer-related cognitive impairment are commonly experienced symptoms that share psychological and physical manifestations. One or more of these symptoms will affect nearly all patients at some point during their course of treatment or survivorship. These side effects are burdensome and reduce patients' quality of life well beyond their cancer diagnosis and associated care treatments. Cancer-related fatigue, insomnia, and cancer-related cognitive impairment are likely to have multiple etiologies that make it difficult to identify the most effective method to manage them. In this review, we summarized the information on cancer-related fatigue, insomnia, and cancer-related cognitive impairment incidence and prevalence among breast cancer patients and survivors as well as recent research findings on pharmaceutical, psychological, and exercise interventions that have shown effectiveness in the treatment of these side effects. Our review revealed that most current pharmaceutical interventions tend to ameliorate symptoms only temporarily without addressing the underlying causes. Exercise and behavioral interventions are consistently more effective at managing chronic symptoms and possibly address an underlying etiology. Future research is needed to investigate effective interventions that can be delivered directly in clinic to a large portion of patients and survivors. © 2017 Wiley Periodicals, Inc.

To explore the actions cancer patients reported they would take in response to a range of common side effects of chemotherapy and whether these were considered appropriate based on current guidelines and evidence; and to explore the sociodemographic and cancer-related variables associated with patients selecting the appropriate action (immediate medical attention or reporting) for two potentially life-threatening side effects: fever, and unusual bleeding and bruising. Four hundred thirty-six medical oncology and haematology patients receiving chemotherapy completed two surveys to provide demographic, disease and treatment characteristics, and details on how they would respond if they experienced a range of specified side effects of chemotherapy (for example, nausea and vomiting, fatigue, and skin rash or nail changes). The proportion of patients reporting the appropriate action for each side effect was calculated. Multiple logistic regressions examined the patient demographic and cancer characteristics associated with selecting the appropriate action (seeking immediate medical attention) for two potentially life-threatening side effects of chemotherapy: high fever of 38 °C or more, and unusual bleeding or bruising. Two thirds of patients indicated that they would seek immediate medical attention for high fever (67%), but only 41% would seek immediate attention for bleeding or bruising. Cancer type and time since diagnosis were significantly associated with patients indicating that they would seek immediate medical attention for high fever; while time since diagnosis was the only variable significantly associated with patients reporting that they would seek immediate medical attention for unusual bleeding or bruising. For chronic side effects, like skin rash or nail changes, and tingling or numbness, which usually do not require urgent reporting, only between 12 and 16% would report them immediately. A significant proportion of patients reported that they would "do nothing" about fatigue or tiredness (24%). By comparison, less than 10% patients reported that they would do nothing for the other side effects investigated. Tools need to be created so that patients better understand the side effects after being treated with chemotherapy and what action they should take.

The widespread patient use of artisanal cannabis preparations has preceded quality validation of cannabis use for epilepsy. Neurologists and cannabinoid specialists are increasingly in a position to monitor and guide the use of herbal cannabis in epilepsy patients. We report the retrospective data on efficacy and adverse effects of artisanal cannabis in Patients with medically refractory epilepsy with mixed etiologies in Washington State, California, and Maine. Clinical considerations, including potential risks and benefits, challenges related to artisanal preparations, and cannabinoid dosing, are discussed. Of 272 combined patients from Washington State and California, 37 (14%) found cannabis ineffective at reducing seizures, 29 (15%) experienced a 1-25% reduction in seizures, 60 (18%) experienced a 26-50% reduction in seizures, 45 (17%) experienced a 51-75% reduction in seizures, 75 (28%) experienced a 76-99% reduction in seizures, and 26 (10%) experienced a complete clinical response. Overall, adverse effects were mild and infrequent, and beneficial side effects such as increased alertness were reported. The majority of patients used cannabidiol (CBD)-enriched artisanal formulas, some with the addition of delta-9-tetrahydrocannabinol (THC) and tetrahydrocannabinolic acid (THCA). Four case reports are included that illustrate clinical responses at doses <0.1mg/kg/day, biphasic dose-response effects, the use of THCA for seizure prevention, the use of THC for seizure rescue, and the synergy of cannabinoids and terpenoids in artisanal preparations.

To report the 6-month single-blinded results of unilateral thalamotomy with MRI-guided focused ultrasound (MRgFUS) in patients with tremors other than essential tremor. Three patients with tremor due to Parkinson disease, 2 with dystonic tremor in the context of cervicobrachial dystonia and writer's cramp, and 1 with dystonia gene-associated tremor underwent MRgFUS targeting the ventro-intermedius nucleus (Vim) of the dominant hemisphere. The primary endpoint was the reduction of lateralized items of the Tremor Rating Scale of contralateral hemibody assessed by a blinded rater. All patients achieved a statistically significant, immediate, and sustained improvement of the contralateral tremor score by 42.2%, 52.0%, 55.9%, and 52.9% at 1 week and 1, 3, and 6 months after the procedure, respectively. All patients experienced transient side effects and 2 patients experienced persistent side effects at the time of last evaluation: hemitongue numbness and hemiparesis with hemihypoesthesia. Vim MRgFUS is a promising, incision-free, but nevertheless invasive technique to effectively treat tremors other than essential tremor. Future studies on larger samples and longer follow-up will further define its effectiveness and safety. NCT02252380. This study provides Class IV evidence that for patients with tremor not caused by essential tremor, MRgFUS of the Vim improves the tremor of the contralateral hemibody at 6 months. © 2017 American Academy of Neurology.

Clinical Significance of Repetitive Compound Muscle Action Potentials in Patients with Myasthenia Gravis: A Predictor for Cholinergic Side Effects of Acetylcholinesterase Inhibitors

PubMed Central

Lee, Hyo Eun; Kim, Yool-hee; Kim, Seung Min

2016-01-01

Background and Purpose Acetylcholinesterase inhibitors (AChEIs) are widely used to treat myasthenia gravis (MG). Although AChEIs are usually tolerated well, some MG patients suffer from side effects. Furthermore, a small proportion of MG patients show cholinergic hypersensitivity and cannot tolerate AChEIs. Because repetitive compound muscle action potentials (R-CMAPs) are an electrophysiologic feature of cholinergic neuromuscular hyperactivity, we investigated the clinical characteristics of MG patients with R-CMAPs to identify their clinical usefulness in therapeutic decision-making. Methods We retrospectively reviewed the clinical records and electrodiagnostic findings of MG patients who underwent electrodiagnostic studies and diagnostic neostigmine testing (NT). Results Among 71 MG patients, 9 could not tolerate oral pyridostigmine bromide (PB) and 17 experienced side effects of PB. R-CMAPs developed in 24 patients after NT. The highest daily dose of PB was lower in the patients with R-CMAPs (240 mg/day vs. 480 mg/day, p<0.001). The frequencies of PB intolerance and side effects were higher in the patients with R-CMAPs than in those without R-CMAPs [37.5% vs. 0% (p<0.001) and 45.8% vs. 12.8% (p=0.002), respectively]. The MG Foundation of America postintervention status did not differ significantly between MG patients with and without R-CMAPs, and the response to immunotherapy was also good in both groups. Conclusions Side effects of and intolerance to AChEIs are more common in MG patients with R-CMAPs than in those without R-CMAPs. AChEIs should be used carefully in MG patients with R-CMAPs. The presence of R-CMAPs after NT may be a good indicator of the risks of PB side effects and intolerance. PMID:27819419

It is acknowledged that almost half of patients initiated on efavirenz will experience at least one neuropsychiatric side effect. The aim was to determine the incidence and severity of neuropsychiatric side effects associated with efavirenz use in five public-sector primary healthcare clinics in the Eastern Cape. The study was a prospective drug utilisation study. A total of 126 medical records were reviewed to obtain the required information. After baseline assessment, follow-up reviews were conducted at 4 weeks, 12 weeks and 24 weeks from 2014 to 2015. The participant group was 74.60% female ( n = 94), and the average age was 37.57±10.60 years. There were no neuropsychiatric side effects recorded for any patient. After the full follow-up period, there were a total of 49 non-adherent patients and one patient had demised. A non-adherent patient was defined as a patient who did not return to the clinic for follow-up assessment and medication refills 30 days or more after the appointed date. Some patients ( n = 11) had sent a third party to the clinic to collect their antiretroviral therapy (ART). The clinic pharmacy would at times dispense a two-month supply of medication resulting in the patient presenting only every two months. Further pharmacovigilance studies need to be conducted to determine the true incidence of these side effects. Healthcare staff must be encouraged to keep complete records to ensure meaningful patient assessments. Patients being initiated on ART need to personally attend the clinic monthly for at least the first 6 months of treatment. Clinic staff should receive regular training concerning ART, including changes made to guidelines as well as reminders of side effects experienced.

Turns (pirouettes) are an important movement in ballet and may be affected by "lateral bias". This study investigated physiological differences exhibited by experienced and novice dancers, respectively, when performing pirouette with dominant and non-dominant leg supports, respectively. Thirteen novice and 13 experienced dancers performed turns on dominant or non-dominant legs. The maximum ankle plantarflexion, knee extension and hip extension were measured during the single-leg support phase. The inclination angle of rotation axis is the angle between instantaneous rotation axis and global vertical axis in the early single-leg support phase. Both groups exhibited a greater hip extension, knee extension, and ankle plantarflexion when performing a turn on the non-dominant leg. For experienced dancers, the inclination angle of rotation axis during the pre-swing phase was generally smaller for dominant leg support than non-dominant leg. However, no significant difference was found in inclination angle of rotation axis of novice dancers. For experienced dancers, an improved performance is obtained when using the dominant leg for support. By contrast, for novice dancers, the performance is independent of choice of support leg. The significant lateral bias in experienced dancers indicates the possible influence of training. That is, repetitive rehearsal on the preferred leg strengthens the impact of side dominance in experienced dancers.

We investigated whether experiencing right- or left-sided facial paralysis would affect an individual's ability to recognize one side of the human face using hybrid hemi-facial photos by preliminary study. Further investigation looked at the relationship between facial recognition ability, stress, and quality of life. To investigate predominance of one side of the human face for face recognition, 100 normal participants (right-handed: n = 97, left-handed: n = 3, right brain dominance: n = 56, left brain dominance: n = 44) answered a questionnaire that included hybrid hemi-facial photos developed to determine decide superiority of one side for human face recognition. To determine differences of stress level and quality of life between individuals experiencing right- and left-sided facial paralysis, 100 patients (right side:50, left side:50, not including traumatic facial nerve paralysis) answered a questionnaire about facial disability index test and quality of life (SF-36 Korean version). Regardless of handedness or hemispheric dominance, the proportion of predominance of the right side in human face recognition was larger than the left side (71% versus 12%, neutral: 17%). Facial distress index of the patients with right-sided facial paralysis was lower than that of left-sided patients (68.8 ± 9.42 versus 76.4 ± 8.28), and the SF-36 scores of right-sided patients were lower than left-sided patients (119.07 ± 15.24 versus 123.25 ± 16.48, total score: 166). Universal preference for the right side in human face recognition showed worse psychological mood and social interaction in patients with right-side facial paralysis than left-sided paralysis. This information is helpful to clinicians in that psychological and social factors should be considered when treating patients with facial-paralysis.

Challenges Evaluating Chemotherapy-Induced Peripheral Neuropathy in Childhood Cancer Survivors.

PubMed

Mohrmann, Caroline; Armer, Jane; Hayashi, Robert J

Children treated for cancer are exposed to a variety of chemotherapeutic agents with known toxicity to the peripheral nervous system. The side effect of peripheral neuropathy can cause changes in sensation, function, and even cause pain. Although peripheral neuropathy is recognized by pediatric oncology nurses as an important and significant side effect, measuring neuropathy can be quite complex for clinical care and research efforts. With more children surviving a cancer diagnosis today, this issue is increasingly important for childhood cancer survivors. This article has reviewed existing literature examining peripheral neuropathy in childhood cancer survivors with particular interest paid to measurement tools available and needs for future research. It is important for nurses to choose appropriate measures for clinical care and research methods in order to have an impact on patients experiencing this condition.

Stress-Induced Tradeoffs in a Free-Living Lizard across a Variable Landscape: Consequences for Individuals and Populations

Current life history theory suggests that the allocation of energetic resources between competing physiological needs should be dictated by an individual’s longevity and pace of life. One key physiological pathway likely to contribute to the partitioning of resources is the vertebrate stress response. By increasing circulating glucocorticoids the stress response can exert a suite of physiological effects, such as altering immune function. We investigated the effects of stress physiology on individual immunity, reproduction and oxidative stress, across an urban landscape. We sampled populations in and around St. George, Utah, examining corticosterone in response to restraint stress, two innate immune measures, reproductive output, and the presence of both reactive oxygen metabolites and antioxidant binding capacity, in populations of common side-blotched lizards (Uta stansburiana) experiencing variable levels of environmental stress. Additionally, using capture-mark-recapture techniques, we examined the relationships between these physiological parameters and population-level differences. Our results reveal elevated physiological stress corresponds with suppressed immunity and increased oxidative stress. Interestingly, urban populations experiencing the most physiological stress also exhibited greater reproductive output and decreased survival relative to rural populations experiencing less physiological stress, demonstrating a tradeoff between reproduction and life maintenance processes. Our results suggest that environmental stress may augment life history strategy in this fast-paced species, and that shifts in life history strategy can in turn affect the population at large. Finally, the urban environment poses definite challenges for organisms, and while it appears that side-blotched lizards are adjusting physiologically, it is unknown what fitness costs these physiological adjustments accrue.

[Aggregate shocks and investment in human capital: higher educational achievement during the lost decade in Mexico.

PubMed

Peña, Pablo A

2013-01-01

This article documents a negative aggregate response in the attainment of postsecondary education (more than 12 years of schooling) in Mexico to the recession of 1982-83 and the stagnation that followed. The response was not homogeneous across genders, regions or family backgrounds. Males experienced a drop in attainment and females experienced a slowdown in attainment growth. On average, states with greater pre-shock educational attainment experienced larger drops. There was no clear trend for the response by family background. However, a negative effect is found even between siblings. The evidence suggests a demand side story: the drop in household income seems to be the main determinant of the fall/slowing down in attainment. The conclusion is that the recession and the lack of growth that ensued had a sizeable and lasting negative impact on skill formation in Mexico.

2016-01-01

The use of compounded bioidentical hormone replacement therapy by menopausal women has become a popular alternative to traditional synthetic conjugated equine estrogen and progestin hormone replacement therapy due to safety concerns raised by recent studies. However, due to the lack of randomized, large-scale trials to evaluate the efficacy and side-effect profile of compounded bioidentical hormone replacement therapy many healthcare providers are reluctant to prescribe such therapy. The purpose of this study was to compare women's menopausal symptom relief and side effects experienced when using compounded bioidentical hormone replacement therapy and traditional hormone replacement therapy. A descriptive comparative design was used. Inferential and descriptive statistical procedures including a paired difference t-test, two-sample t-test, and f-tests (percentage, mean, standard deviation, frequency) were run on the Statistical Package for the Social Sciences. The framework used to guide this study was Lenz and Pugh's Theory of Unpleasant Symptoms. Surveys were distributed once to a convenient sample of women aged 35 and older when they dropped off or picked up their prescriptions at a pharmacy. Of the 216 surveys distributed, 70 were returned from those women taking compounded bioidentical hormone replacement therapy and 53 from traditional hormone replacement therapy. The survey contained 15 questions pertaining to age, duration of hormone replacement therapy, type and formulation of hormone replacement therapy, reasons for initiating hormone replacement therapy, symptoms before and one month after hormone replacement therapy, and side effects related to hormone replacement therapy. Included in part 1 of this series of articles was the introduction to the study conducted and the results of the literature review that was conducted for the purpose of examining the current data related to the topic of hormone replacement therapy. Part 2 provides a brief discussion on the significance of this study to nursing and provides the methods used in this study.

Flupirtine, a functional NMDA antagonist, does not seem to be efficacious in the treatment of tinnitus. The purpose of this study was to investigate whether flupirtine has any beneficial effect on tinnitus perception. Twenty-four patients were selected (6 female and 18 male patients) with continuous subjective tinnitus. Eight patients suffered left-sided tinnitus, 4 right-sided tinnitus and 12 bilateral tinnitus. We assessed the burden of the tinnitus by loudness visual analogue scale (VAS) and tinnitus questionnaire (TQ) according to Hallam et al., and Hiller and Goebel. All patients were treated with a 2 x 100 mg daily dosage of oral flupirtine for 3 weeks in an open prospective design. There was no statistical effect on VAS and TQ of the treatment with flupirtine. Only one patient (4.2%) experienced a positive effect on the tinnitus but discontinued the treatment because of amnesia and concentration disorders.

Immediate versus delayed self-reporting of symptoms and side effects during chemotherapy: does timing matter?

The aim of this study was to examine how patients recall symptoms at a delayed self-report. Accurate insight into toxicity symptoms during chemotherapy is essential so that nurses and doctors can assess therapeutic tolerance and adjust supportive care accordingly. A non-experimental, longitudinal design was employed. Using the Therapy-Related Symptoms Checklist (TRSC), respondents (n = 142) reported their initial symptoms during the first 7 days of the chemotherapy cycle at two different times: (1) each day of the first seven days after the chemotherapy administration (immediate self-report), and (2) at their next hospital visit for chemotherapy (delayed self-report). We compared the number and severity of symptoms and side effects reported in the immediate and delayed self-reports. Respondents reported significantly fewer symptoms and fewer severe symptoms in the delayed self-report. For 22 out of 25 symptoms the delayed-reported grade was significantly lower than the immediate-reported maximum grade. Compared to the immediate-reported median grade, significant differences occurred in only 10 out of the 25 symptoms. In all cases, except fatigue, the delayed-reported grade was significantly higher than the immediate-reported median grade. This study indicates that delayed self-report of chemotherapy side effects is not an appropriate measure of actual symptoms and side effects experienced by patients. Delayed self-report gives a weaker insight into actual symptom burden. Fatigue is at particular risk to be minimized at the delayed self-report. Therefore it is recommended to assess chemotherapy-related symptoms and side effects by means of immediate self-report. Copyright © 2010 Elsevier Ltd. All rights reserved.

The combined use of oral medroxyprogesterone acetate and methyltestosterone in a male contraceptive trial programme.

Bain, J; Rachlis, V; Robert, E; Khait, Z

1980-04-01

A male contraceptive trial was undertaken in 23 men using a combination of oral medroxyprogesterone acetate (MPA) and oral methyltestosterone (MeT). The men were divided into four groups according to varying drug dosages and were followed for 15 months (control - 3 months, treatment - 6 months, follow-up - 6 months). The parameters assessed included sperm count and motility, serum gonadotropins and sex steroids, and several biochemical and hematological tests. A questionnaire dealing with side-effects and changes in sexual function was administered intermittently. Although sperm count was suppressed (most dramatically at the highest drug doses, MPA 20mg,MeT 20mg), it was not suppressed to infertile levels. Sperm motility was unaltered; LH was modestly suppressed, FSH was not suppressed; testosterone was suppressed even at low doses; dihydrotestosterone responses were inconsistent. No significant biochemical abnormalities or side-effects occurred although some men experienced mild transient acne, gynecomastia and decreased testicular size. We conclude that in the doses used in this trial, the combination of MPA and MeT is not effective for male contraceptive, purposes and that higher doses may induce severe and undesirable side-effects.

Neuroversion: using electroconvulsive therapy as a bridge to deep brain stimulation implantation.

2017-02-01

Parkinson's disease (PD) is a movement disorder with significant neuropsychiatric comorbidities. Electroconvulsive therapy (ECT) is effective in treating these neuropsychiatric symptoms; however, clinicians are reluctant to use ECT in patients with deep brain stimulation (DBS) implantations for fear of damaging the device, as well as potential cognitive side effects. Right unilateral ultra-brief pulse (RUL UBP) ECT has a more favorable cognitive side-effect profile yet has never been reported in PD patients with DBS implants. We present a case series of three patients with a history of PD that all presented with psychiatric decompensation immediately prior to planned DBS surgery. All three patients had DBS electrode(s) in place at the time and an acute course of ECT was utilized in a novel method to "bridge" these individuals to neurosurgery. The patients all experienced symptom resolution (psychosis and/or depression and/or anxiety) without apparent cognitive side effects. This case series not only illustrates that right unilateral ultra-brief pulse can be utilized in patients with DBS electrodes but also illustrates that this intervention can be utilized as a neuromodulatory "bridge", where nonoperative surgical candidates with unstable psychiatric symptoms can be converted to operative candidates in a manner similar to electrical cardioversion.

2013-01-01

A panel study examining the effects of individual characteristics, side effects experienced, and service quality on contraceptive discontinuation was undertaken in four urban areas of Honduras. Data were collected from October 2006 to December 2007. The baseline population included 800 women aged 15–44 who were new or continuing users of the injectable, IUD, or oral contraceptive pill. A total of 671 women (84%) were re-interviewed after one year. Life tables and Cox proportional hazards models are used to present discontinuation rates and factors associated with contraceptive discontinuation. Among new users, discontinuation of the baseline method at 12 months was high (45%); especially for users of the injectable (50%). In the hazards model, service quality had little effect on discontinuation, while individual characteristics and the experience of specific side effects showed significant effects. The results suggest that programs should emphasize continuous contraceptive coverage rather than continuous use of a particular method. PMID:21500697

Dietary and botanical anxiolytics

Summary Drugs used to treat anxiety have many negative side effects including addiction, depression, suicide, seizures, sexual dysfunction, headaches and more. Anxiolytic medications do not restore normal levels of neurotransmitters but instead manipulate the brain chemistry. For example, selective serotonin reuptake inhibitors (SSRIs) prevent the reuptake of serotonin from the synapse allowing serotonin to remain in the area of activity for a longer period of time but does not correct the lack of serotonin production. Benzodiazepines, such as Valium and Xanax®, stimulate GABA receptors, thus mimicking the calming effects of GABA but again do not fix the lack of GABA production. Often, the brain becomes accustomed to these medications and they often lose their effectiveness, requiring higher doses or different drugs. In contrast to anxiolytic drugs, there are herbs and nutrients which can stimulates neurotransmitter synthesis and more naturally effect and even adjust brain chemistry in the absence of many of the side effects experienced with drugs. Therefore this paper explores several herbal and nutritional approaches to the treatment of anxiety. PMID:22460105

To systematically review the effectiveness of medical treatment for Cushing's syndrome in clinical practice, regarding cortisol secretion, clinical symptom improvement, and quality of life. To assess the occurrence of side effects of these medical therapies. Eight electronic databases were searched in March 2017 to identify potentially relevant articles. Randomized controlled trials and cohort studies assessing the effectiveness of medical treatment in patients with Cushing's syndrome, were eligible. Pooled proportions were reported including 95% confidence intervals. We included 35 articles with in total 1520 patients in this meta-analysis. Most included patients had Cushing's disease. Pooled reported percentage of patients with normalization of cortisol ranged from 35.7% for cabergoline to 81.8% for mitotane in Cushing's disease. Patients using medication monotherapy showed a lower percentage of cortisol normalization compared to use of multiple medical agents (49.4 vs. 65.7%); this was even higher for patients with concurrent or previous radiotherapy (83.6%). Mild side effects were reported in 39.9%, and severe side effects were seen in 15.2% of patients after medical treatment. No meta-analyses were performed for clinical symptom improvement or quality of life due to lack of sufficient data. This meta-analysis shows that medication induces cortisol normalization effectively in a large percentage of patients. Medical treatment for Cushing's disease patients is thus a reasonable option in case of a contraindication for surgery, a recurrence, or in patients choosing not to have surgery. When experiencing side effects or no treatment effect, an alternate medical therapy or combination therapy can be considered.

Knowledge-based planning (KBP) is a promising technique that can improve plan quality and increase planning efficiency. However, no attempts have been made to extend the domain of KBP for planners with different planning experiences so far. The purpose of this study was to quantify the potential gains for planners with different planning experiences after implementing KBP in intensity modulated radiation therapy (IMRT) plans for left-sided breast cancer patients. The model libraries were populated with 80 expert clinical plans from treated patients who previously received left-sided breast-conserving surgery and IMRT with simultaneously integrated boost. The libraries were created on the RapidPlan TM . 6 planners with different planning experiences (2 beginner planners, 2 junior planners and 2 senior planners) generated manual and KBP optimized plans for additional 10 patients, similar to those included in the model libraries. The plan qualities were compared between manual and KBP plans. All plans were capable of achieving the prescription requirement. There were almost no statistically significant differences in terms of the planning target volume (PTV) coverage and dose conformality. It was demonstrated that the doses for most of organs-at-risk (OARs) were on average lower or equal in KBP plans compared to manual plans except for the senior planners, where the very small differences were not statistically significant. KBP data showed a systematic trend to have superior dose sparing at most parameters for the heart and ipsilateral lung. The observed decrease in the doses to these OARs could be achieved, particularly for the beginner and junior planners. Many differences were statistically significant. It is feasible to generate acceptable IMRT plans after implementing KBP for left-sided breast cancer. KBP helps to effectively improve the quality of IMRT plans against the benchmark of manual plans for less experienced planners without any manual intervention. KBP showed promise for homogenizing the plan quality by transferring planning expertise from more experienced to less experienced planners.

Nonaxial thrusts produced by solid rocket motors during three-axis stabilized attitude control have been determined from ascent experience on twenty three Burner II, Burner IIA and Block 5D-1 upper stage vehicles. A data base representing four different rocket motor designs (three spherical and one extended spherical) totaling twenty five three-axis stabilized firings is generated. Solid rocket motor time-varying resultant and lateral side force vector magnitudes, directions and total impulses, and roll torque couple magnitudes, directions, and total impulses are tabulated in the appendix. Population means and three sigma deviations are plotted. Existing applicable ground test side force and roll torque magnitudes and total impulses are evaluated and compared to the above experience data base. Within the spherical motor population, the selected AEDC ground test data consistently underestimated experienced motor side forces, roll torques and total impulses. Within the extended spherical motor population, the selected AEDC test data predicted experienced motor side forces, roll torques, and total impulses, with surprising accuracy considering the very small size of the test and experience populations.

Succinylcholine revolutionized anaesthetic practice by providing intense neuromuscular blockade of very rapid onset and ultrashort duration, thereby greatly easing the maneuver of tracheal intubation. However the worth of succinylcholine is limited by the frequent occurrence of muscular side effects which manifest biochemically in the form of rise in serum creatine kinase (CK). The administration of small doses of nondepolarizing muscle relaxants before the administration of succinylcholine has been shown to decrease the incidence and severity of muscular side effects experienced by the patients. This study was aimed at evaluating the efficacy of technique in reducing the muscular side effects of succinylcholine, biochemically manifested as rise in CK. Sixty healthy adults were enrolled in the study who were scheduled for minor muscle cutting surgeries under general anaesthesia. They were assigned at random to two groups of thirty patients each. They randomly received succinylcholine for intubation and a precurarization dose of rocuronium followed by succinylcholine for intubation. Blood samples were drawn for estimation of serum creatinine kinase. There was a significantly raised CK in the succinylcholine group. In the precurarization group the rise in CK was prevented and the levels were significantly less as compared to the group which received succinylcholine alone. Present study concluded that precurarization with rocuronium was effective in reducing the succinylcholine-induced rise in creatinine kinase.

A survey of patients' receipt of prescription drug information

A nationwide telephone survey of 1,223 individuals investigated the nature and source of information provided to patients regarding prescription drugs. About half of the respondents said that they had received information from their doctor about the purpose and directions for use for their most recent prescription. Only a few people (11 per cent) said that they had been informed about the drug's side effects and 19 per cent said that they had been told nothing by their doctor. Most (72 per cent) related that nothing had been said to them at the pharmacy. Written information (stickers on the medicine container,more » leaflets or brochures) were said to be infrequently provided at the pharmacy. About 12 per cent of the respondents said they had expected they might get a drug side effect, but only 9 per cent said that they had experienced one. The most frequently cited action in response to side effects was to consult the physician (40 per cent); however, a sizeable percentage of people stopped the medicine completely or temporarily (36 per cent) or kept on taking the drug as prescribed (32 per cent).« less

Thorium abundances of basalt ponds in South Pole-Aitken basin: Insights into the composition and evolution of the far side lunar mantle

2011-01-01

Imbrian-aged basalt ponds, located on the floor of South Pole-Aitken (SPA) basin, are used to provide constraints on the composition and evolution of the far side lunar mantle. We use forward modeling of the Lunar Prospector Gamma Ray Spectrometer thorium data, to suggest that at least five different and distinct portions of the far side lunar mantle contain little or no thorium as of the Imbrian Period. We also use spatial correlations between local thorium enhancements and nonmare material on top of the basalt ponds to support previous assertions that lower crustal materials exposed in SPA basin have elevated thorium abundances, consistent with noritic to gabbronoritic lithologies. We suggest that the lower crust on the far side of the Moon experienced multiple intrusions of thorium-rich basaltic magmas, prior to the formation of SPA basin. The fact that many of the ponds on the lunar far side have elevated titanium abundances indicates that the far side of the Moon experienced extensive fractional crystallization that likely led to the formation of a KREEP-like component. However, because the Imbrian-aged basalts contain no signs of elevated thorium, we propose that the SPA impact event triggered the transport of a KREEP-like component from the lunar far side and concentrated it on the nearside of the Moon. Because of the correlation between basaltic ponds and basins within SPA, we suggest that Imbrian-aged basaltic volcanism on the far side of the Moon was driven by basin-induced decompressional melting.

Is By-passing the Stomach a Means to Optimise Sodium Bicarbonate Supplementation? A Case-study With a Post-Bariatric Surgery Individual.

Sodium bicarbonate (SB) is an ergogenic supplement shown to improve high-intensity exercise via increased blood bicarbonate buffering. Substantial amounts of the ingested bicarbonate are neutralised in the stomach. Bariatric surgery results in a small gastric pouch which dramatically reduces exposure time of any ingested food in the stomach. The aim of this study was to examine the pharmacokinetics of orally ingested SB in a post-gastric bypass individual to determine the magnitude of changes in blood bicarbonate and associated side-effects. We hypothesized that SB supplementation in a gastric bypass model would result in greater blood bicarbonate increases and less side-effects than in healthy individuals due to minimal bicarbonate losses in the stomach. One post-bariatric male ingested 0.3 g·kg -1 BM of SB on three occasions (SB1, SB2, SB3) and 0.3 g·kg -1 BM of placebo (PL) on a further occasion. Blood bicarbonate was determined before and every 10-min following supplement ingestion for 3 h and then every 20 min for a further 1 h. Side-effects were reported using an adapted questionnaire at identical time points. Maximal increases in blood bicarbonate with SB were +20.0, +15.2 and +12.6 mM, resulting in maximal bicarbonate concentrations of 42.8, 39.3 and 36.2 mM. Area under the curve was SB1: 8328, SB2: 7747, SB3: 7627 mM·min -1 and 6436 mM·min -1 for PL. Side-effects with SB were scarce. Maximal bicarbonate increases were well above those shown previously, with minimal side-effects, indicative of minimal neutralisation of bicarbonate in the stomach. The large increases in circulating bicarbonate and minimal side-effects experienced by our post-gastric surgery patient are indicative that minimising neutralisation of bicarbonate in the stomach, as would occur with enteric coated capsules, may optimise SB supplementation and thus warrants investigation.

The appropriate use of antiretrovirals reduces morbidity and mortality caused by HIV infection. The present article provides health care professionals with a practical guide for the use of antiretrovirals. Therapy should be initiated based predominantly on clinical presentation and CD4 count, and should consist of three active drugs or at least two active drugs when this is not possible, as in cases of some treatment-experienced patients. This is the most effective way to achieve long-term suppression of viral replication. Selection of individual drugs in the regimen should consider the weight of the evidence supporting these choices, as well as their tolerability profiles and ease of use, the patients' comorbidities and treatment history. Treatment interruption is not recommended, either in aviremic patients or in those who have experienced virological failure. Instead, the therapeutic regimen should be adjusted to minimize side effects, promote adherence and suppress viral replication.

Although statins have been shown to reduce cardiovascular disease mortality, less than half of U.S. adults achieve their low-density lipoprotein cholesterol goal. In many patients initiated on a statin, adherence rates decrease over time. To characterize current and former statin users, identify reasons for the discontinuation or switching of statins, and identify factors associated with adherence. The USAGE survey is a cross-sectional, self-administered Internet-based survey of 10,138 U.S. adults fielded September to October 2011. The following statin users were identified and compared: adherent nonswitchers, adherent switchers, non-adherent switchers, and discontinuers. Univariate and multivariate models using a priori covariates for adherence and discontinuation were examined. Most participants were current statin users who adhered with their prescribed statin (82.5%, n = 8371). Former statin users or discontinuers (12%, n = 1220) cited muscle pain, a side effect, as the primary reason for discontinuation (60%), followed by cost (16%), and then perceived lack of efficacy (13%). Discontinuers were less satisfied with their physicians' explanation of cholesterol treatment, more likely to use the Internet to research statins, and less likely to undergo frequent cholesterol monitoring. Among adherent statin users, the primary reasons for switching were muscle side effects (33%) and cost (32%). Individuals at risk for non-adherence included those with low household income, those who experienced muscle pain as a side effect while on statin therapy, and those taking medication for cardiovascular disease. Statin-related muscle side effects are common and contribute significantly to rates of discontinuation, switching, and non-adherence. Improved physician patient communication about side effects and benefits of statins are necessary to improve both adherence and outcomes. Copyright © 2013 National Lipid Association.

Pegylated-interferon-α/ribavirin (PEG-IFN/RBV) treatment can cure hepatitis C virus (HCV) infection but has frequent neuropsychiatric side-effects. Patients with pre-existing psychiatric illness may not be offered therapy. We established prevalence of self-reported psychiatric comorbidity among HCV-infected patients in a hospital-liver clinic, and determined the impact of such diagnoses on uptake and tolerance to PEG-IFN/RBV. All HCV cases referred for assessment in Australian Capital Territory/surrounding regions April 2004-March 2012 were entered into a clinical database. We conducted univariate and multivariate analyses of variables correlating with uptake of antiviral therapy and frequency of treatment-related side-effects. Of 773 referred patients, 235 (30%) described pre-existing psychiatric illness. Among these, 26% received antiviral therapy, compared with 30% of 538 without psychiatric comorbidity. History of depression (usually validated by liaison psychiatry) was associated with higher incidence of treatment-related neuropsychiatric side-effects (odds ratio 2.79 [1.35-5.70], P < 0.05) but did not affect treatment outcome. Twenty-seven patients reported schizophrenia: three (11%) received antiviral therapy, compared with 30% admitting depression and 20% with bipolar affective disorder (all assessed by psychiatrist). In most schizophrenia cases, the reason for not offering antiviral treatment was psychological illness, yet none of five treated (these three plus two others in a psychiatric rehabilitation facility) experienced worsening psychiatric symptoms. A history of depression is common with hepatitis C but does not affect initiation of antiviral treatment, despite substantially increased risk of psychiatric side-effects. In contrast, pre-existing schizophrenia appears to influence treatment decisions, despite little evidence that PEG-IFN/RBV exacerbates the psychiatric condition, and well-supervised antiviral therapy can have good outcomes.

Sea level rise (SLR) in response to looming climate change is being considered as a major impediment to coastal areas. Acute wave activities and tidal propagations of semi-diurnal to mixed type are impairing the morphology of the Indus Delta in Pakistan. In this study a synthetic approach has been adopted using multi sensor satellite and ground data in order to integrate the individual effect of topography, oceanic activities and vegetative canopy for deduction of a synergic impact over the morphology of the Indus Delta creeks system from 1972 to 2017. Geomorphologic anomalies in the planform of fourteen major creeks were explored. Spatiotemporal variations suggested that a substantial amount of the delta alluvium had been engulfed by the Arabian Sea. On average, the creeks located on the right side of the Indus River were relatively less wide (3.9 km) than those of on the left side (5.2 km). Zonal statistics calculated with topographic position index (TPI) enabled to understand the tide induced inundation extents. The mangrove canopy on the right side was found greater, which is why tidal basins on that side experienced less erosive activities. Thus, it could be maintained that the coastal sedimentary processes may be monitored effectively with the remotely sensed data and temporal pattern of changes can be quantified for future planning and mitigation of adverse effects.

Cardiovascular disease is one of the most common causes of death worldwide, with many individuals having experienced acute coronary syndrome (ACS). How patients with a history of ACS value aspects of their medical treatment have been evaluated rarely. The aim of this study was to determine patient priorities for long-term drug therapy after experiencing ACS. To identify patient-relevant treatment characteristics, a systematic literature review and qualitative patient interviews were conducted. A questionnaire was developed to elicit patient's priorities for different characteristics of ACS treatment using Analytic Hierarchy Process (AHP). To evaluate the patient-relevant outcomes, the eigenvector method was applied. Six-hundred twenty-three patients participated in the computer-assisted personal interviews and were included in the final analysis. Patients showed a clear priority for the attribute "reduction of mortality risk" (weight: 0.402). The second most preferred attribute was the "prevention of a new myocardial infarction" (weight: 0.272), followed by "side effect: dyspnea" (weight: 0.165) and "side effect: bleeding" (weight: 0.117). The "frequency of intake" was the least important attribute (weight: 0.044). In conclusion, this study shows that patients strongly value a reduction of the mortality risk in post-ACS treatment. Formal consideration of patient preferences and priorities can help to inform a patient-centered approach, clinical practice, development of future effective therapies, and health policy for decision makers that best represents the needs and goals of the patient.

The Effect of Hock Injury Laterality and Lameness on Lying Behaviors and Lying Laterality in Holstein Dairy Cows

2017-01-01

Simple Summary Dairy cattle may experience discomfort in a myriad of ways throughout their life cycle, particularly when sustaining hock injuries or suboptimal locomotion. Lactating dairy cattle divide their lying time equally between left and right sides; however, discomfort experienced during pregnancy or following cannulation can cause a shift in the normal lying laterality. The objective of this study was to determine the effect of hock injuries and lameness on the lying behaviors of dairy cattle, particularly lying laterality. Lying laterality did not differ from the expected 50% (left side lying time) in cattle with hock injuries, lameness, or both. The current results suggest that lying laterality does not differ between varying levels of hock injury or lameness severity. Going forward, further research could determine if lying laterality shifts over the course of the animal developing a hock injury or lameness. Abstract Lactating dairy cattle divide their lying equally between their left side and their right side. However, discomfort, such as pregnancy and cannulation, can cause a cow to shift lying side preference. The objective of this study was to determine the effect of lameness and hock injuries on lying behaviors, particularly lying laterality, of lactating dairy cows. Cows from four commercial farms in eastern Croatia that had lying behavior data, health score data, and production records were used in the study. Health scores including hock injuries and locomotion were collected once per cow. Severely lame cows had greater daily lying time compared to sound cows and moderately lame cows. Overall, cows spent 51.3 ± 1.2% of their daily lying time on the left side. Maximum hock score, locomotion score, hock injury laterality, or parity did not result in lying laterality differing from 50%. PMID:29149044

Film clips and narrative text are useful techniques in eliciting emotion in a laboratory setting but have not been examined side-by-side using the same methodology. This study examined the self-identification of emotions elicited by film clip and narrative text stimuli to confirm that selected stimuli appropriately target the intended emotions. Seventy participants viewed 30 film clips, and 40 additional participants read 30 narrative texts. Participants identified the emotion experienced (happy, sad, angry, fearful, neutral-six stimuli each). Eighty-five percent of participants self-identified the target emotion for at least two stimuli for all emotion categories of film clips, except angry (only one) and for all categories of narrative text, except fearful (only one). The most effective angry text was correctly identified 74% of the time. Film clips were more effective in eliciting all target emotions in participants for eliciting the correct emotion (angry), intensity rating (happy, sad), or both (fearful).

Are Medications Involved in Vision and Intracranial Pressure Changes Seen in Spaceflight?

NASA Technical Reports Server (NTRS)

Wotring, V. E.

2015-01-01

Some crewmembers have experienced changes in their vision after long-duration spaceflight on the ISS. These impairments include visual performance decrements, development of cotton-wool spots or choroidal folds, optic-disc edema, optic nerve sheath distention, and/or posterior globe flattening with varying degrees of severity and permanence. These changes are now used to define the visual impairment/intracranial pressure (VIIP) syndrome. It is known that many medications can have side effects that are similar to VIIP symptoms. Some medications raise blood pressure, which can affect intracranial pressure. Many medications that act in the central nervous system can affect intracranial pressures and/or vision. About 40% of the medications in the ISS kit are known to cause side effects involving changes in blood pressure, intracranial pressure and/or vision. For this reason, we have begun an investigation of the potential relationship between ISS medications and their risk of causing or exacerbating VIIP-like symptoms.

The role of intravenous immunoglobulin in treatment of mucous membrane pemphigoid: A review of literature

PubMed Central

Tavakolpour, Soheil

2016-01-01

Background: Mucous membrane pemphigoid (MMP) is considered an autoimmune blistering disease that predominantly affects mucous membranes. Various treatments are available for controlling the diseases, but not all of them may respond. Materials and Methods: PubMed and Google Scholar were searched for all the associated studies until 2015, using the keywords such as “cicatricial pemphigoid” or “ocular pemphigoid” or “mucous membrane pemphigoid” or “MMP” and “intravenous immunoglobulin” or “IVIg” to find all the relevant studies. The last search update was for September 2, 2015. Among the searched items, only English studies were included in the review. Results: After excluding nonrelevant studies, 13 studies with a total number of seventy patients with MMP who were under treatment with IVIg were analyzed. The 65 patients responded completely, one did not respond, two had partially responded, and the remaining two patients stopped IVIg therapy, which resulted in ocular cicatricial pemphigoid progression. Majority of the studies reported mild adverse effects while two of them did not report any unwanted side effect. The most common side effect was headache, followed by nausea. Most of the patients who had a cessation of IVIg therapy before achieving clinical remission experienced the disease progression. Conclusion: Overall, it can be concluded that IVIg therapy was very helpful in treatment of MMP patients who did not respond to conventional therapy or stopped using them for various side effects. Adverse effects associated with IVIg therapy were considerably lower than conventional therapy that can lead toward treatment with this agent in patients who suffer from severe side effects.

In Rheumatology, non-steroidal anti-inflammatory drugs (NSAIDs) has been widely prescribed and used. However, despite their clinical benefits in the management of inflammatory and degenerative joint disease, NSAIDs have considerable side effects, mostly affecting the upper gastrointestinal system, which therefore, limit their use. This study was conducted to determine the patients' knowledge and perception regarding the used of NSAIDS. A total of 120 patients who attended the rheumatology clinic Hospital, Raja Permaisuri Bainun, Malaysia, and received NSAIDs more than 3 months were interviewed irrespective of their rheumatological conditions. Patient's knowledge and perception on the side effects of NSAIDs were recorded. Fifty-four percent of the patients obtained information regarding the side effect of NSAIDs either from the rheumatologist, rheumatology staff nurse or other medical staffs (75.4%). The remaining 45.8% were naive of such knowledge. Fifteen percent obtained the information by surfing the internet and 9.2% from printed media. Twenty-four (24.2%) patients, experienced indigestion and/or stomach discomfort attributed to NSAIDs used. Two patients (1.7%) had hematemesis and malena once. This study shows that half of the patients who attended the rheumatology clinic were unaware of the side effect of NSAIDs. Available data showed that most of the knowledgeable patients are more conscience and self-educated. This study also reveals the important roles of clinicians, trained staff nurses as well as the pharmacist in providing the guidance and knowledge of any medication taken by patients.

The two sides of adversity: the effect of distant versus recent adversity on updating emotional content in working memory.

Previous research suggests that adversity can have both adaptive and maladaptive effects, yet the emotional and working memory processes that contribute to more or less adaptive outcomes are unclear. The present study sought to investigate how updating emotional content differs in adolescents who have experienced past, recent, or no adversity. Participants who had experienced distant adversity (N = 53), no adversity (N = 58), or recent adversity only (N = 20) performed an emotion n-back task with emotional facial expressions. Results revealed that the distant adversity group exhibited significantly faster reaction times (RTs) than the no adversity and recent adversity only groups. In contrast, the recent adversity only group exhibited significantly slower RTs and more errors than the distant adversity and no adversity groups. These results suggest an emotion and executive control pathway by which both the benefits and negative effects of adversity may be conferred. Results also highlight the importance of time in assessing the impact of adversity.

Prostate-specific membrane antigen (PSMA) is highly expressed on prostate epithelial cells and strongly up-regulated in prostate cancer (PC), making it an optimal target for the treatment of metastasized PC. Radioligand therapy (RLT) with 177Lu-PSMA-DKFZ-617 (Lu-PSMA) is a targeted therapy for metastatic PC. In this study, we retrospectively analyzed the side effects and the response rate of 24 hormone and/or chemorefractory PC patients with a mean age of 75.2 years (range: 64–82) with distant metastases and progressive disease according to the PSA level, who were treated with Lu-PSMA. Median PSA was 522 ng/ml (range: 17–2360). Forty-six cycles of Lu-PSMA were performed. Of the 24 patients, 22 received two cycles. Eight weeks after the first cycle of Lu-PSMA therapy 79.1% experienced a decline in PSA level. Eight weeks after the second cycle of Lu-PSMA therapy 68.2% experienced a decline in PSA relative to the baseline value. Apart from two cases of grade 3 anemia, there was no relevant hemato- or nephrotoxicity (grade 3 or 4). These results confirmed that Lu-PSMA is a safe treatment option for metastatic PC patients and has a low toxicity profile. A positive response to therapy in terms of decline in PSA occurs in about 70% of patients. PMID:26871285

Radiotherapy is one of the primary treatment strategies for cancer. However, patients not only deal with the side-effects of radiotherapy, but they must also endure the psychological distress caused by cancer. This study explores how cancer patients adapt to the treatment process when receiving radiotherapy. This study used a grounded theory approach, and eight in-depth interviews were conducted with newly diagnosed cancer patients who received radiotherapy as a primary treatment. The core category that emerged from this study was "the desire to survive". The categories and subcategories that emerged from the data include facing unknown situations (e.g. searching for relevant information and decision-making considerations, and listening to healthcare professionals' suggestions), experiencing the pain of treatment (e.g. tolerating side-effects, tolerating inconvenience during the treatment, accepting support during the treatment, and adjusting lifestyles), and chances to extend life (e.g. accepting fate, determination to undergo the treatment, and adjusting negative emotions). The study results provide a better understanding of the experiences of cancer patients undergoing radiotherapy. Healthcare professionals should provide effective medical management for side-effects and psychological support to cancer patients during the journey of radiotherapy. © 2014 The Authors.

To compare the efficacy and tolerability of surgical excision and radiotherapy with those of cryotherapy and intralesional steroid treatment of keloids. Twenty-six patients with a total of 76 keloids were enrolled in this study. Nineteen patients with 44 keloids underwent surgical excision combined with immediate 12-Gy irradiation (group A) while the remaining 9 patients with 32 keloids received multiple sessions of intralesional steroid treatment after cryotherapy which continued until flattening of lesion(s) occurred (group B). Two patients were included in both treatment groups. All patients were followed up at regular intervals for at least 1 year. In both treatment groups, keloids responded well without any major side effect. While patients of group A were all satisfied, those of group B (with a mean number of treatment sessions of 5.84 +/- 2.51) experienced more side effects, a more prolonged course, a higher recurrence rate and less satisfaction. This study showed that surgery plus immediate postoperative irradiation was an effective and relatively safe choice for treatment of keloids. Although cryotherapy combined with intralesional steroids was associated with more side effects and higher relapse rates, it could be a good choice for small and newly formed keloids.

Poor secretion of transplanted submandibular glands (SMGs) during the latent period may cause duct obstruction and affects the surgical outcome. The objective of this study was to investigate the efficacy and systemic side effects of carbachol on transplanted SMG secretion. Twenty-seven patients who underwent SMG transplantation for severe keratoconjunctivitis sicca were treated with subcutaneous injections of 0.2mg/2ml carbachol at 10 days, 1 month, and/or 3 months after surgery. The effect on secretion was evaluated by Schirmer test and technetium 99m ((99m)Tc) scintigraphy. Systemic side effects were evaluated subjectively using a questionnaire. The results showed that the time to onset varied from 4 to 9min and the duration of action from 50 to 110min after carbachol administration. The secretion at each time point after drug administration was significantly higher than the pre-administration value (all P<0.01). (99m)Tc scintigraphy showed a decline in the dynamic time-activity curve in 26 patients, demonstrating a stimulatory effect on the secretion of carbachol. No serious systemic side effects were experienced. In conclusion, the intermittent administration of carbachol could be an effective and safe strategy to promote secretion from transplanted SMGs in the latent period to prevent duct obstruction.

A NEW ANTIEMETIC FOR THE TREATMENT OF NAUSEA AND VOMITING ASSOCIATED WITH ROENTGEN THERAPY

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

Codiga, V.A.

Thiethylperazine dimaleate was administered orally or rectally in 56 patients for treatment of nausea or vomiting associated with radiation (2000 to 5000 r). The oral form had a quicker onset of action. Fifty patients (89%) experienced satisfactory response with either oral tablets or suppositories, the latter being used when oral tolerance was poor. Only 2 complained of side effects attributable to thiethylperazine dimaleate. One patient experienced transient blurred vision and tinnitus and another noted sialorrhea plus diminished gustatory sensation. In view of the observed high percentage of favorable responses with the drug and its lack of ataractic action, the rolemore » of psychogenic factors in gastrointestinal disturbance associated with roentgen ray therapy would seem to be slight.

To evaluate the safety and efficacy of an East Indian sandalwood oil (EISO) product as a topical treatment for molluscum contagiosum. Ten subjects ranging in age from 22 months to 29 years were recruited. Subjects were instructed to apply an EISO product to the lesions twice daily. Subjects were monitored every two to three weeks during the study and were questioned regarding local or systemic side effects. Assessment of response was recorded by counting lesions and documented by photographs. Nine of ten subjects (90%) experienced complete resolution of molluscum lesions within the twelve week study period. Response was unrelated to lesion size or number, how long the molluscum rash had been present, or patient age or gender. There were no complaints of side effects, skin irritation, pain, or other adverse events reported in any subjects. In this pilot open label study, an EISO product proved to be an effective treatment for molluscum contagiosum lesions with resolution of lesions typically occurring within twelve weeks of therapy.

Granulocyte colony-stimulating factor (G-CSF) is now widely used for stem cell mobilization. We evaluated the role of post-G-CSF white blood cell (WBC) counts and donor factors in predicting adverse events and yields associated with mobilization. WBC counts were determined at baseline, after the third and the fifth dose of G-CSF in 476 healthy donors. Donors with WBC ≥ 50 × 10(3)/μL post the third dose of G-CSF experienced more fatigue, myalgia/arthralgia, and chills, but final post-G-CSF CD34(+) cell counts were similar. Although the final CD34(+) cell count was higher in donors with WBC ≥ 50 × 10(3)/μL post the fifth G-CSF, the incidence of side effects was similar. Females more frequently experienced headache, nausea/anorexia, vomiting, fever, and lower final CD34(+) cell count than did males. Donors with body mass index (BMI) ≥ 25 showed higher incidences of sweat and insomnia as well as higher final CD34(+) cell counts. Donor receiving G-CSF ≥ 10 μg/kg tended to experience bone pain, headache and chills more frequently. Multivariate analysis indicated that female gender is an independent factor predictive of the occurrence of most side effects, except for ECOG > 1 and chills. Higher BMI was also an independent predictor for fatigue, myalgia/arthralgia, and sweat. Higher G-CSF dose was associated with bone pain, while the WBC count post the third G-CSF was associated with fatigue only. In addition, one donor in the study period did not complete the mobilization due to suspected anaphylactoid reaction. Observation for 1 h after the first injection of G-CSF is required to prevent complications from unpredictable side effects.

How to generalize from randomized placebo controlled trials of ADHD drug treatment in adults to 'real-world' clinical practice is intriguing. This open-labeled prospective observational study examined the effectiveness of long-term stimulant and non-stimulant medication in adult ADHD including dose, side-effects and comorbidity in a clinical setting. A specialized ADHD outpatient clinic gave previously non-medicated adults (n=250) with ADHD methylphenidate as first-line drug according to current guidelines. Patients who were non-tolerant or experiencing low efficacy were switched to amphetamine or atomoxetine. Primary outcomes were changes of ADHD-symptoms evaluated with the Adult ADHD Self-Report Scale (ASRS) and overall severity by the Global Assessment of Functioning (GAF). Secondary outcomes were measures of mental distress, and response on the Clinical-Global-Impressions-Improvement Scale. Data at baseline and follow-ups were compared in longitudinal mixed model analyses for time on-medication, dosage, comorbidity, and side-effects. As results, 232 patients (93%) completed examination at the 12 month endpoint, and 163 (70%) remained on medication. Compared with the patients who discontinued medication, those still on medication had greater percentage reduction in ASRS-scores (median 39%, versus 13%, P<0.001) and greater improvement of GAF (median 20% versus 4%, P<0.001) and secondary outcomes. Continued medication and higher cumulated doses showed significant associations to sustained improvement. Conversely, psychiatric comorbidity and side-effects were related to lower effectiveness and more frequent termination of medication. Taken together, one-year treatment with stimulants or atomoxetine was associated with a clinically significant reduction in ADHD symptoms and mental distress, and improvement of measured function. No serious adverse events were observed. Copyright © 2014 Elsevier B.V. and ECNP. All rights reserved.

The personally experienced development of chemotherapy for tuberculosis during the last half century represents some highlights of new knowledges and practical successes: the discovery of antituberculosis drugs; the comprehension of their actions and side effects; the exploration of mechanisms of resistance against antituberculosis agents; the evaluation of therapeutic and epidemiologic consequences of resistant strains; the decoding of the mycobacterial genetic structure. For different economic, social and psychologic reasons, the worldwide results of the battle against tuberculosis are not nearly as good as possible. AIDS is only a partial factor of this failure.

2017-01-01

Chemotherapy-induced peripheral neuropathy (CIPN) is a common dose-limiting side effect experienced by patients receiving treatment for cancer. Approximately 30–40% of patients treated with neurotoxic chemotherapy will develop CIPN and there is considerable variability in its severity between patients. It is often sensory-predominant with pain and can lead to long-term morbidity in survivors. The prevalence and burden of CIPN late effects will likely increase as cancer survival rates continue to improve. In this review, we discuss the approach to peripheral neuropathy in patients with cancer and address the clinical phenotypes and pathomechanisms of specific neurotoxic chemotherapeutic agents.

Low level laser or light treatment on the various clinical condition is getting considerable attention now. However, there has been no report about the clinical effect of low level polarized polychromatic noncoherent light (LPPL) on the inflammatory skin disease. We experienced a case of acrodermatitis continua in a pregnant woman refractory to any conventional treatment including the most potent topical steroid. She was successfully treated with LPPL. LPPL could be a possible treatment modality producing substantial clinical result in inflammatory skin condition without any side-effect. PMID:21394319

A randomized trial of dexamethasone and acetazolamide for acute mountain sickness prophylaxis.

Forty-seven climbers participated in a double-blind, randomized trial comparing acetazolamide 250 mg, dexamethasone 4 mg, and placebo every eight hours as prophylaxis for acute mountain sickness during rapid, active ascent of Mount Rainier (elevation 4,392 m). Forty-two subjects (89.4 percent) achieved the summit in an average of 34.5 hours after leaving sea level. At the summit or high point attained above base camp, the group taking dexamethasone reported less headache, tiredness, dizziness, nausea, clumsiness, and a greater sense of feeling refreshed (p less than or equal to 0.05). In addition, they reported fewer problems of runny nose and feeling cold, symptoms unrelated to acute mountain sickness. The acetazolamide group differed significantly (p less than or equal to 0.05) from other groups at low elevations (1,300 to 1,600 m), in that they experienced more feelings of nausea and tiredness, and they were less refreshed. These drug side effects probably obscured the previously established prophylactic effects of acetazolamide for acute mountain sickness. Separate analysis of an acetazolamide subgroup that did not experience side effects at low elevations revealed a prophylactic effect of acetazolamide similar in magnitude to the dexamethasone effect but lacking the euphoric effects of dexamethasone. This study demonstrates that prophylaxis with dexamethasone can reduce the symptoms associated with acute mountain sickness during active ascent and that acetazolamide can cause side effects that may limit its effectiveness as prophylaxis against the disease.

Driver injury in near- and far-side impacts: Update on the effect of front passenger belt use.

Parenteau, Chantal S; Viano, David C

2018-04-03

This is a study that updates earlier research on the influence of a front passenger on the risk for severe driver injury in near-side and far-side impacts. It includes the effects of belt use by the driver and passenger, identifies body regions involved in driver injury, and identifies the sources for severe driver head injury. 1997-2015 NASS-CDS data were used to investigate the risk for Maximum Abbreviated Injury Scale (MAIS) 4 + F driver injury in near-side and far-side impacts by front passenger belt use and as a sole occupant in the driver seat. Side impacts were identified with GAD1 = L or R without rollover (rollover ≤ 0). Front-outboard occupants were included without ejection (ejection = 0). Injury severity was defined by MAIS and fatality (F) by TREATMNT = 1 or INJSEV = 4. Weighted data were determined. The risk for MAIS 4 + F was determined using the number of occupants with known injury status MAIS 0 + F. Standard errors were determined. Overall, belted drivers had greater risks for severe injury in near-side than far-side impacts. As a sole driver, the risk was 0.969 ± 0.212% for near-side and 0.313 ± 0.069% for far-side impacts (P < .005). The driver's risk was 0.933 ± 0.430% with an unbelted passenger and 0.596 ± 0.144% with a belted passenger in near-side impacts. The risk was 2.17 times greater with an unbelted passenger (NS). The driver's risk was 0.782 ± 0.431% with an unbelted passenger and 0.361% ± 0.114% with a belted passenger in far-side impacts. The risk was 1.57 times greater with an unbelted passenger (P < .10). Seat belt use was 66 to 95% effective in preventing MAIS 4 + F injury in the driver. For belted drivers, the head and thorax were the leading body regions for Abbreviated Injury Scale (AIS) 4+ injury. For near-side impacts, the leading sources for AIS 4+ head injury were the left B-pillar, roof, and other vehicle. For far-side impacts, the leading sources were the other occupant, right interior, and roof (8.5%). Seat belt use by a passenger lowered the risk of severe driver injury in side impacts. The reduction was 54% in near-side impacts and 36% in far-side impacts. Belted drivers experienced mostly head and thoracic AIS 4+ injuries. Head injuries in the belted drivers were from contact with the side interior and the other occupant, even with a belted passenger.

OBJECTIVE Continuous β-cell rest with diazoxide preserves residual endogenous insulin production in type 1 diabetes. However, side effects have hampered therapeutic usefulness. In a double-blind study, we tested whether lower, intermittent dosing of diazoxide had beneficial effects on insulin production, metabolic control, and autoimmunity markers in the absence of side effects. RESEARCH DESIGN AND METHODS Forty-one newly diagnosed type 1 diabetic patients were randomized to 6 months of treatment with placebo or 100 mg diazoxide at bedtime. A1C, C-peptide (fasting and glucagon stimulated), and FoxP3+ regulatory T-cells (Tregs) were measured. Patients were followed for 6 months after intervention. RESULTS Of six dropouts, three were due to perceived side effects; one subject in the diazoxide group experienced rash, another dizziness, and one in the placebo group sleep disturbance. Adverse effects in others were absent. Diazoxide treatment reduced A1C from 8.6% at baseline to 6.0% at 6 months and 6.5% at 12 months. Corresponding A1C value in the placebo arm were 8.3, 7.3, and 7.5% (P < 0.05 for stronger reduction in the diazoxide group). Fasting and stimulated C-peptide decreased during 12 months similarly in both arms (mean −0.30 and −0.18 nmol/l in the diazoxide arm and −0.08 and −0.09 nmol/l in the placebo arm). The proportion of Tregs was similar in both arms and remained stable during intervention but was significantly lower compared with nondiabetic subjects. CONCLUSIONS Six months of low-dose diazoxide was without side effects and did not measurably affect insulin production but was associated with improved metabolic control. PMID:20028939

Although supported employment increases job acquisition for people with serious mental illness, data on participants' job tenure have been variable. This study evaluated the effects of a standardized work skills training program (the Workplace Fundamentals Module [WPFM]) on job tenure and other work outcomes among individuals receiving individual placement and support (IPS). The effects of two atypical antipsychotic medications on side effects were also tested. The primary hypothesis tested was that participants in IPS plus WPFM would have increased job tenure compared with those enrolled in IPS only, and the secondary hypothesis was that different antipsychotic medications would yield unique side effects. A 2×2 randomized controlled trial compared work outcomes, including job tenure, of participants receiving IPS with or without WPFM for up to two years after obtaining a job. Participants were also randomly assigned to olanzapine or risperidone. Measures of work outcomes, clinical status, and medication side effects were collected. Among 107 participants, 63% obtained at least one job. WPFM did not increase job tenure (51.53 and 41.37 total weeks worked for IPS only and IPS plus WPFM, respectively) or affect other work outcomes. Participants on olanzapine experienced increased body mass index, whereas those on risperidone lost weight, but medications did not differentially affect clinical or job outcomes. Clinic-based skills training did not improve work outcomes accruing from IPS. Risperidone, compared with olanzapine, may reduce body mass but has no differential effect on other work or clinical outcomes.

Objective In Rheumatology, non-steroidal anti-inflammatory drugs (NSAIDs) has been widely prescribed and used. However, despite their clinical benefits in the management of inflammatory and degenerative joint disease, NSAIDs have considerable side effects, mostly affecting the upper gastrointestinal system, which therefore, limit their use. This study was conducted to determine the patients’ knowledge and perception regarding the used of NSAIDS. Methods A total of 120 patients who attended the rheumatology clinic Hospital, Raja Permaisuri Bainun, Malaysia, and received NSAIDs more than 3 months were interviewed irrespective of their rheumatological conditions. Patient’s knowledge and perception on the side effects of NSAIDs were recorded. Result Fifty-four percent of the patients obtained information regarding the side effect of NSAIDs either from the rheumatologist, rheumatology staff nurse or other medical staffs (75.4%). The remaining 45.8% were naive of such knowledge. Fifteen percent obtained the information by surfing the internet and 9.2% from printed media. Twenty-four (24.2%) patients, experienced indigestion and/or stomach discomfort attributed to NSAIDs used. Two patients (1.7%) had hematemesis and malena once. Conclusion This study shows that half of the patients who attended the rheumatology clinic were unaware of the side effect of NSAIDs. Available data showed that most of the knowledgeable patients are more conscience and self-educated. This study also reveals the important roles of clinicians, trained staff nurses as well as the pharmacist in providing the guidance and knowledge of any medication taken by patients. PMID:23226825

Experiences With a Self-Reported Mobile Phone-Based System Among Patients With Colorectal Cancer: A Qualitative Study.

2016-06-09

In cancer care, mobile phone-based systems are becoming more widely used in the assessment, monitoring, and management of side effects. To explore the experiences of patients with colorectal cancer on using a mobile phone-based system for reporting neurotoxic side effects. Eleven patients were interviewed (ages 44-68 years). A semistructured interview guide was used to perform telephone interviews. The interviews were transcribed verbatim and analyzed with qualitative content analysis. The patients' experiences of using a mobile phone-based system were identified and constructed as: "being involved," "pacing oneself," and "managing the questions." "Being involved" refers to their individual feelings. Patients were participating in their own care by being observant of the side effects they were experiencing. They were aware that the answers they gave were monitored in real time and taken into account by health care professionals when planning further treatment. "Pacing oneself" describes how the patients can have an impact on the time and place they choose to answer the questions. Answering the questionnaire was easy, and despite the substantial number of questions, it was quickly completed. "Managing the questions" pointed out that the patients needed to be observant because of the construction of the questions. They could not routinely answer all the questions. Patients understood that side effects can vary during the cycles of treatment and need to be assessed repeatedly during treatment. This mobile phone-based system reinforced the patients' feeling of involvement in their own care. The patients were comfortable with the technology and appreciated that the system was not time consuming.

Adherence to treatment is a complex and poorly understood phenomenon. This study investigates the relationship between older depressed patients' adherence to antidepressants and their beliefs about and knowledge of the medication. Assessment was undertaken of 108 outpatients over the age of 55 years diagnosed with depressive disorder and treated for at least four weeks with antidepressants. Adherence was assessed using two self-report measures: the Medication Adherence Rating Scale (MARS) and a Global Adherence Measure (GAM). Potential predictors of adherence investigated included sociodemographic, medication and illness variables. In addition, 33 carers were interviewed regarding general medication beliefs. 56% of patients reported 80% or higher adherence on the GAM. Sociodemographic variables were not associated with adherence on the MARS. Specific beliefs about medicines, such as "my health depends on antidepressants" (necessity) and being less worried about becoming dependant on antidepressants (concern) were highly correlated with adherence. General beliefs about medicines causing harm or being overprescribed, experiencing medication side-effects and severity of depression also correlated with poor adherence. Linear regression with the MARS as the dependent variable explained 44.3% of the variance and showed adherence to be higher in subjects with healthy specific beliefs who received more information about antidepressants and worse with depression severity and autonomic side-effects. Our findings strongly support a role for specific beliefs about medicines in adherence. Challenging patients' beliefs, providing information about treatment and discussing side-effects could improve adherence. Poor response to treatment and medication side-effects can indicate poor adherence and should be considered before switching medications.

Men have higher incidence and mortality rates for nearly all cancers. They are less likely than women to utilise cancer information services and other social support services. The aim of this study was to explore and compare the experience and coping behaviour of men and women after treatment for colorectal cancer (CRC). A longitudinal qualitative study was conducted involving 38 individuals (24 men and 14 women) with CRC. Data were generated using semi-structured interviews at four time points over an 18-month period, post-diagnosis. Interviews focused on participant's experience of CRC and on how gender affected their coping. This paper reports the findings of interviews 3 and 4 which examined the participant's experience after chemotherapy. Three themes emerged from the interviews ('new normal', living with uncertainty and support needs). Many men and women reacted similarly; however, there was some variation evident between and within sexes. The main difference was with regard to the long-term physical side effects of the illness. Many women admitted to still experiencing side effects, whereas many men indicated that they had no problems. These men engaged in practices that aligned with their gender identity and view of masculinity. It must be noted that some men and women were still experiencing an impact. Recovery from the physical and psychological effects of CRC does not occur simultaneously. Healthcare professionals should be aware that not all men (or women) conform to the social stereotypes of masculinity (or femininity). Copyright © 2010 John Wiley & Sons, Ltd.

The aim of this study was to investigate the impact of caregiver knowledge and experience on muscle activity and perceived exertion while repositioning bedridden patients. Subjects were 40- to 65-year-old female caregivers divided into novice and experienced groups. Subjects from both groups performed home-care repositioning techniques on bedridden patients while muscle activity was recorded via electromyogram. Recordings were made from four muscles on the subjects' dominant side: the latissimus dorsi, the biceps brachii, the erector spinae, and the rectus femoris. The subjective burden involved in repositioning was also assessed using the rate of perceived exertion (RPE) and visual analog scales (VAS). Rectus femoris percentage of maximum voluntary contraction (%MVC) values were significantly lower than latissimus dorsi, erector spinae, and biceps brachii values in the novice group. %MVC values from the latissimus dorsi and biceps brachii were significantly higher among the novice group compared to the experienced group. RPE ratings from the novice group were significantly higher than those of the experienced group, and there was a non-significant trend for higher VAS values for the low back, arms, and legs in the novice group compared to the experienced group. Novice caregivers tended to change the patient's position by pulling with the upper limbs without using the lower limbs. In contrast, experienced caregivers exerted less energy by communicating with the patient and utilizing the patient's own movements. They used large, distributed muscle groups that effectively harnessed body mechanics and prevented excess exertion.

2016-10-01

We have taken a novel approach using oral rapamycin - sirolimus - as a medical adjunct to percutaneous therapy in patients with in-stent stenosis and high risk of right ventricular failure. Peripheral pulmonary artery stenosis can result in right ventricular hypertension, dysfunction, and death. Percutaneous pulmonary artery angioplasty and stent placement acutely relieve obstructions, but patients frequently require re-interventions due to re-stenosis. In patients with tetralogy of Fallot or arteriopathy, the problem of in-stent stenosis contributes to the rapidly recurrent disease. Rapamycin was administered to 10 patients (1.5-18 years) with peripheral pulmonary stenosis and in-stent stenosis and either right ventricular hypertension, pulmonary blood flow maldistribution, or segmental pulmonary hypertension. Treatment was initiated around the time of catheterisation and continued for 1-3 months. Potential side-effects were monitored by clinical review and blood tests. Target serum rapamycin level (6-10 ng/ml) was accomplished in all patients; eight of the nine patients who returned for clinically indicated catheterisations demonstrated reduction in in-stent stenosis, and eight of the 10 patients experienced no significant side-effects. Among all, one patient developed diarrhoea requiring drug discontinuation, and one patient experienced gastrointestinal bleeding while on therapy that was likely due to an indwelling feeding tube and this patient tolerated rapamycin well following tube removal. Our initial clinical experience supports that patients with peripheral pulmonary artery stenosis can be safely treated with rapamycin. Systemic rapamycin may provide a novel medical approach to reduce in-stent stenosis.

The appropriate use of antiretrovirals reduces morbidity and mortality caused by HIV infection. The present article provides health care professionals with a practical guide for the use of antiretrovirals. Therapy should be initiated based predominantly on clinical presentation and CD4 count, and should consist of three active drugs or at least two active drugs when this is not possible, as in cases of some treatment-experienced patients. This is the most effective way to achieve long-term suppression of viral replication. Selection of individual drugs in the regimen should consider the weight of the evidence supporting these choices, as well as their tolerability profiles and ease of use, the patients’ comorbidities and treatment history. Treatment interruption is not recommended, either in aviremic patients or in those who have experienced virological failure. Instead, the therapeutic regimen should be adjusted to minimize side effects, promote adherence and suppress viral replication. PMID:22654926

Do the emotional side-effects of hormonal contraceptives come from pharmacologic or psychological mechanisms?

2004-01-01

Hormonal preparations have become one of the most popular methods used for controlling fertility. The literature over the last 40 years continues to reveal how their numerous side effects negatively impact many users and even society at large. Three large cohort trials were the first to demonstrate, on a grand scale, certain emotional and behavioral associations with contraceptive use. Current contraceptive use was associated with an increase rate in depression, divorce, tranquilizer use, sexual dysfunction, and suicide and other violent and accidental deaths. Despite the advent of more "user friendly" contraceptives, the discontinuation rate secondary to side effects has changed little through the years. While in rare cases hormonal preparations can be deadly to the user, there is substantial evidence that their negative effect issues more from their emotional and behavioral properties. This paper reviews the results of over seven studies which further characterize these prominent associations, particularly with hormonal contraception, in an attempt to demonstrate their association with the intrinsic pharmacologic properties of hormonal preparations. Hormonal contraceptive users, in contrast with non users, were found to have higher rates of depression, anxiety, fatigue, neurotic symptoms, sexual disturbances, compulsion, anger, and negative menstrual effects. The question of whether the association of these maladies is directly due to the effect of taking exogenous hormones versus the psychological impact of the contraceptive behavior itself had yet to be studied. Seven small randomized-controlled trials were found in a review of the literature which studied this hypothesis in a direct way. They do not support the origination of these side effects being from the pharmacological properties of hormones. No association was found between hormone levels and emotional functioning in females. Psychiatric evaluations among IUD and oral contraceptive pill (OCP) users reveal no significant differences. Women who were given an OCP placebo experienced a similar side effect profile of OCP users. Different hormonal concentrations and combinations made no significant difference in the side effect profile. A study of women who were given either "weak female hormones" or a placebo failed to duplicate the side effect profile found in all of the other studies where the hormones were labeled as contraceptives. The evidence suggests that most of the side effects of hormonal contraception are a result of a psychological response to the practice of contraception. More study is warranted to further understand this psychological phenomenon, especially now that an effective non-contraceptive method of fertility regulation and more reliable psychological instruments are available. Furthermore, it is reasonable to hypothesize, given the present data, that contraceptive activity itself is inherently damaging to women.

The programmed-death-1 inhibitors selectively block programmed-death-1 interaction with its receptor, which restores active T-cell response directed at tumor cells, inducing an anti-tumor effect. This nonspecific activation of the immune system can also lead to a wide spectrum of side effects. Nivolumab has been used effectively to prolong survival in patients with metastatic melanoma and is recommended as a category 1 agent for systemic therapy in metastatic or unresectable melanoma per the National Comprehensive Cancer Network guidelines. We present a case of a 64-year-old woman who began nivolumab therapy for metastatic melanoma. After six doses of nivolumab therapy, the patient experienced generalized hypopigmentation on her face, chest, back, arms, and lower extremities. Although vitiligo has been reported in as many as 10.7% of patients undergoing nivolumab therapy in some clinical trials, we believe this is the first case to describe the progression of nivolumab-induced vitiligo in a metastatic melanoma patient. This case provides significant insight into the onset, symptoms, development, and treatment options for patients experiencing vitiligo as a result of nivolumab therapy.

López, P.; Casassa, G.

2011-12-01

Ice elevation changes of the Northern Patagonia Icefield (NPI) were analyzed by comparing three Digital Elevation Models (DEM) corresponding to 1975 (constructed based on topographic maps), the SRTM DEM of 2000 yr and a SPOT 5 DEM of 2005. In addition, the glacier length fluctuations and the surface area evolution between 2001 and 2011 of 25 glaciers of the NPI were studied: the information extracted from the Landsat ETM+ satellite image of 11 March 2001 was compared to the measurements performed based on the Landsat ETM+ satellite image of 19 February 2011. From a global point of view, the majority of the studied glaciers thinned, retreated and lost surface between 2001 and 2011, only few glaciers (Leones, Nef, Pared Sur and Soler) located on the eastern side of the NPI have been stable. Glaciers located on the western side of the NPI suffered a stronger wasting compared to the glaciers located on the eastern side. Overall, over the ablation areas of the NPI (below 1150 m a.s.l.) a more rapid thinning of 2.6 m yr-1 occurred between 2000 and 2005 yr compared to the period 1975-2000, in which a mean thinning of 1.7 m yr-1 was measured for the same zones of the NPI. For the whole period (1975-2005) the most important thinning of the ablation areas has been estimated for HPN-1 Glacier (4.4 m yr-1) followed by Benito (3.4 m yr-1), Fraenkel (2.4 m yr-1), Gualas (2.1 m yr-1) and Acodado glaciers, all of them located on the western side of the NPI. Between 2001 and 2011, a noteworthy retreat of 1.9 km was experienced by Gualas Glacier and by Reichert Glacier with 1.6 km, both located on the north-western side of the NPI. On the south-western side of the NPI, during the same decennia, Steffen Glacier experienced a remarkable retreat of 1.6 km as well. During the 2001-2011 period, Steffen Glacier more than doubled its rate of retreat (compared to the 1979-2001 period) and experienced the disintegration of its main front as well as a lateral tongue that retreated 3.1 km. The most significant retreat observed on the eastern side was experienced by Colonia Glacier (1 km). Area loss was also relevant during the period 2001-2011. Overall, the icefield experienced a reduction of 50.6 km2 which represents a 1.3 % relative to the surface area calculated for 2001 yr. The most remarkable surface reduction was observed for HPN-1 Glacier that lost 3.2 % of its surface estimated in 2001, followed by Steffen Glacier (2.8 %). We suggest that the glacier shrinking observed in the NPI is controlled firstly by atmospheric warming, as it has been reported in this area. Nevertheless, updated climatic studies are needed in order to confirm this suggestion. If the detected past climate trends persist, in the future, glaciers of the NPI will continuous or even increase their rate of shrinking generating important consequences for this region like the production of Glacier Lake Outburst Flood events or the decrease of the melt-water runoff in the long-term future.

Photodynamic therapy (PDT) is an effective treatment for actinic keratoses, Bowen's disease and basal cell carcinoma. The main drawback of PDT is pain during application. To compare the efficacy of supratrochlear and supraorbital nerve block with cold air analgesia to control the pain experienced during PDT. A controlled open clinical trial was conducted in 34 patients having multiple actinic keratoses in the frontal region treated with PDT. On one side of the frontal region the supratrochlear and supraorbital nerves were blocked, while on the other side cold air was used as the method of analgesia. Pain was recorded on a visual analogue scale after treatment. Thirty-one of 34 patients reported less pain in the zone treated with nerve block. This difference was statistically significant. Nerve block is superior to cold air and is an easy, safe, effective means of controlling the pain associated with PDT.

Yanto, Theo Audi; Kosasih, Felicia Nathania

2018-01-01

Background Metformin is widely known as an antidiabetic agent which has significant gastrointestinal side effects, but nightmares and abnormal dreams as its adverse reactions are not well reported. Case Presentation Herein we present a case of 56-year-old male patient with no known history of recurrent nightmares and sleep disorder, experiencing nightmare and abnormal dreams directly after consumption of 750 mg extended release metformin. He reported his dream as an unpleasant experience which awakened him at night with negative feelings. The nightmare only lasted for a night, but his dreams every night thereafter seemed abnormal. The dreams were vivid and indescribable. The disappearance and occurrence of abnormal dreams ensued soon after the drug was discontinued and rechallenged. The case was assessed using Naranjo Adverse Drug Reaction (ADR) probability scale and resulted as probable causality. Conclusion Metformin might be the underlying cause of nightmare and abnormal dreams in this patient. More studies are needed to confirm the association and causality of this findings. PMID:29581904

Chronic pain is a prevalent condition in the United States. Musculoskeletal pain, including joint and back pain, is the most common type of chronic pain, and many patients with back pain have a neuropathic component. Pain has direct economic consequences. While oxycodone controlled-release (CR) is one of the most widely used oral long-acting opioids for pain, including pain with a neuropathic component, it is often associated with bothersome side effects, resulting in additional medical resource use (MRU) and costs. To examine the impact on MRU and costs to payers of side effects in patients taking oxycodone CR alone or in combination with other pain medications for noncancer pain (including those with neuropathic pain symptoms). A nationwide convenience sample of adults in the United States, who participated in a survey research panel and reported current use of oxycodone CR for noncancer pain, completed an online survey between November 2, 2010, and December 13, 2010. Respondents were excluded if they reported current use of other extended-release or long-acting opioid prescription medications. The survey consisted of questions on demographics, clinical characteristics, pain characteristics, experience with pain medication, and MRU associated with side effects. Payer costs were calculated based on the MRU reported by the respondents multiplied by Medicare reimbursement rates for hospitalizations and outpatient visits and average wholesale price (AWP) minus 20% for medications. A subgroup of patients who reported neuropathic pain symptoms also was examined. After applying the exclusion criteria, 432 respondents completed the survey. Approximately half of the respondents (n = 219; 50.7%) reported neuropathic pain symptoms. The majority of respondents were Caucasian (88.4%) and female (63.7%) with an average age of 41.8 years (14.89). Respondents most frequently reported low back pain (41.2%), followed by osteoarthritis/rheumatoid arthritis (20.4%), neuropathic pain (10.6%), and fibromyalgia (9.0%). Respondents reported having their pain condition for an average of 5.4 (7.42) years. On days when taken, respondents reported a mean oxycodone CR daily dose of 83.3 mg (126.93) taken in an average of 2 doses. Most respondents (82.4%) reported experiencing at least 1 side effect with 77.5% being bothered by at least 1 side effect. The most frequently reported side effects ( greater than 25%) were drowsiness (41.4%), constipation (37.0%), fatigue or daytime sleepiness (36.6%), and dizziness (27.1%). Among respondents who reported being bothered by one or more side effects in the previous month, MRU associated with side effects was reported by 39.1% of respondents and significantly increased as the level of side-effect bother increased from 19.8% among those "A little bit bothered" to 38.4% among those "Bothered" to 61.0% among those "Extremely bothered" (P less than 0.001). Additionally, total average payer costs (in 2010 dollars) per respondent in the previous month associated with side effects were $238 ($1,159) and also significantly increased as the level of side-effect bother increased from $61 ($512) among those "A little bit bothered" to $238 ($1,160) among those "Bothered" to $425 ($1,561) among those "Extremely bothered" (P less than 0.001). Results reported in the neuropathic pain subgroup were similar to results reported in the total study sample. Among adults taking oxycodone CR for chronic noncancer pain (with or without a neuropathic pain component), over three-fourths reported being bothered by side effects. Respondents who reported higher levels of side-effect bother also reported greater MRU, resulting in increased payer costs. The results of this study provide further support of the econo-mic burden to payers associated with opioid-related side effects in patients with chronic noncancer pain, with and without neuropathic pain.

A Case Report: Subanesthetic Ketamine Infusion for Treatment of Cancer-Related Pain Produces Urinary Urge Incontinence.

Oncology patients undergoing treatment can experience substantial pain related to their disease or prescribed therapy. Ketamine infusions at subanesthetic doses have been used at our institution to supplement the pain management regimens of 262 patients. We present 2 cases in which young adult patients being treated with subanesthetic ketamine for cancer-related pain experienced urinary urgency and incontinence after initiation or increase of the ketamine infusion. This adverse effect has not been reported previously at this dosing range. These case reports suggest that subanesthetic ketamine infusions may cause side effects that previously have been reported only at anesthetic or abuse doses.

A thermosphere composition measurement using a quadrupole mass spectrometer with a side energy focussing quasi-open ion source

The atomic oxygen concentration in the altitude range 130 to 240 km was determined through the use of a quadrupole spectrometer with a strongly focussing ion source. The instrument is used in the Thermosphere Probe in a manner that greatly increases the proportion of measured oxygen ions that have not experienced a surface collision and permits quantitative evaluation of surface recombination and thermalization effects which inevitably enter all spectrometer determinations. The data obtained strengthen the concept that consideration of surface effects is significant in quantifying spectrometer measurements of reactive gases, and tend to be in agreement with von Zahn's recent results.

Pain is commonly diagnosed with respect to cancer and heart diseases, being a major symptom in most neoplastic diseases. Uncontrolled pain leads to a decrease in the quality of life and an increase in the morbidity of the patient. Opioids represent the best analgetic supportive therapy and are frequently used in patients suffering from cancer and experiencing a high level of pain. Opioid treatment starts with a gradual titration of the dose until the minimum effective dose and the maximum tolerated dose are determined. Opioid rotation refers to the switch from one opioid to another in order to get a better response to analgetic therapy and reduce side effects. Fentanyl therapy is recommended to be continued during chemotherapy, radiotherapy, or in the case of surgical intervention. Rotation to fentanyl patches is an efficient and elegant solution for cancer patients, with reduced side effects. Opioid rotation, especially to fentanyl, was shown to increase the quality of life in patients with malignant disease. Finally, rotation to fentanyl is also advantageous from an economic point of view. PMID:28223843

Experiences and coping strategies of oncology patients undergoing oral chemotherapy: First steps of a grounded theory study.

Chemotherapies are increasingly available for oral application. Previous studies have focussed on differences between orally and intravenously administered chemotherapies, mostly following quantitative designs surveying patients' preferences and adherence. The lived experience of patients undergoing oral chemotherapy has been rarely explored. Therefore, this study investigates how patients experience oral chemotherapy. We conducted open interviews with six patients and two spouses. Recruitment took place in the outpatient clinic of an urban Swiss hospital. Data collection and analysis followed the principles of Straussian grounded theory. The participants reported physical and emotional reluctance towards oral chemotherapy as well as toxic side effects. Feeling responsible emerged as a core phenomenon. All participants intended to adhere to the therapy although this was challenging because of the complex medication regimen. Belief in the effectiveness of the therapy was a strengthening factor. All participants reported to be highly adherent to oral chemotherapy. Although they experienced some toxic side effects, they did not react. Monitoring toxicities and support in everyday life should be a core feature of care. Copyright © 2016 Elsevier Ltd. All rights reserved.

2013-01-01

Oxaliplatin, an anti-cancer chemotherapeutic agent used for the treatment of colorectal cancer, commonly causes gastrointestinal side-effects such as constipation, diarrhoea, nausea, and vomiting. Damage to enteric neurons may underlie some of these gastrointestinal side-effects, as the enteric nervous system (ENS) controls functions of the bowel. In this study, neuronal loss and changes to the structure and immunoreactivity of myenteric neuronal nitric oxide synthase (nNOS) neurons were examined in colonic segments from mice following exposure to oxaliplatin ex vivo and following repeated intraperitoneal injections of oxaliplatin over 3 weeks in vivo, using immunohistochemistry and confocal microscopy. Significant morphological alterations and increases in the proportion of NOS-immunoreactive (IR) neurons were associated with both short-term oxaliplatin exposure and long-term oxaliplatin administration, confirming that oxaliplatin causes changes to the myenteric neurons. Long-term oxaliplatin administration induced substantial neuronal loss that was correlated with a reduction in both the frequency and propagation speed of colonic migrating motor complexes (CMMCs) in vitro. Similar changes probably produce some symptoms experienced by patients undergoing oxaliplatin treatment. PMID:23486839

Look Good Feel Better (LGFB) aims to help women manage appearance-related side effects of cancer and its treatment. In this pilot study, we assessed the impact of LGFB workshops on self-image, social interactions, perceived social support, and anxiety. We administered scales preworkshop and postworkshop participation. We conducted semistructured telephone interviews following attendance. Statistically and qualitatively, subjects experienced significant improvement in self-image, social interaction, and anxiety. Participant anxiety decreased, but greater social support was anticipated than actually obtained. LGFB workshops increase self-image, improve social interactions, and reduce anxiety.

Ocular changes with oxaliplatin.

Ocular toxicity, although uncommon, can occur with many chemotherapeutic agents. Platinum compounds have been documented to produce a variety of ocular side effects, and reports have been made of ocular toxicity with oxaliplatin. This article reports on four patients who experienced ocular symptoms while receiving oxaliplatin. The symptoms included tunnel vision and visual loss with postural changes. One patient had objective findings that included papilledema. All of the changes were reversible. Oxaliplatin will continue to be used widely, so clinicians treating patients with it must be alert for unusual toxicities such as those described in this article.

Nausea and vomiting are two of the most troubling side effects patients experience during chemotherapy. While newly available treatments have improved our ability to manage nausea and vomiting, anticipatory and delayed nausea and vomiting are still a major problem for patients receiving chemotherapy. Many cancer patients will delay or refuse future chemotherapy treatments and contemplate stopping chemotherapy altogether because of their fear of experiencing further nausea and vomiting. The purpose of this article is to provide an overview of the patho-psychophysiology of chemotherapy-induced nausea and vomiting and the recommended guidelines for treatment. PMID:24466408

Weight gain represents a frequent side effect of antipsychotic drug treatment. The current trial investigated the effect of add-on treatment with sibutramine in schizophrenia outpatients who had gained more than 7% of weight during the course of treatment. This 24-week placebo-controlled study evaluated the effects of sibutramine added to ongoing antipsychotic treatment. Weight, waist-hip ratio, BMI, blood pressure/pulse and ECG were monitored regularly. In addition, several laboratory tests were performed. Psychopathological symptoms and side effects were assessed frequently. Fifteen patients were assigned randomly to add-on treatment with sibutramine 10 mg or placebo. The two groups did not differ in weight, sociodemographic, or clinical data. Eleven patients were considered for statistical analysis. Significant weight loss was observed in the sibutramine group (mean = -6.1 kg), whereas patients on placebo experienced a mean weight gain of 1.9 kg. A reduction in HbA1c was apparent in the sibutramine but not in the placebo group. No significant between-group differences were found in changes in psychopathology or drug safety. This pilot trial suggests that adjunctive treatment with sibutramine may be safe and effective in schizophrenic patients with antipsychotic-induced weight gain.

Experiences With a Self-Reported Mobile Phone-Based System Among Patients With Colorectal Cancer: A Qualitative Study

PubMed Central

2016-01-01

Background In cancer care, mobile phone-based systems are becoming more widely used in the assessment, monitoring, and management of side effects. Objective To explore the experiences of patients with colorectal cancer on using a mobile phone-based system for reporting neurotoxic side effects. Methods Eleven patients were interviewed (ages 44-68 years). A semistructured interview guide was used to perform telephone interviews. The interviews were transcribed verbatim and analyzed with qualitative content analysis. Results The patients' experiences of using a mobile phone-based system were identified and constructed as: “being involved,” “pacing oneself,” and “managing the questions.” “Being involved” refers to their individual feelings. Patients were participating in their own care by being observant of the side effects they were experiencing. They were aware that the answers they gave were monitored in real time and taken into account by health care professionals when planning further treatment. “Pacing oneself” describes how the patients can have an impact on the time and place they choose to answer the questions. Answering the questionnaire was easy, and despite the substantial number of questions, it was quickly completed. “Managing the questions” pointed out that the patients needed to be observant because of the construction of the questions. They could not routinely answer all the questions. Patients understood that side effects can vary during the cycles of treatment and need to be assessed repeatedly during treatment. Conclusions This mobile phone-based system reinforced the patients’ feeling of involvement in their own care. The patients were comfortable with the technology and appreciated that the system was not time consuming. PMID:27282257

Use of energy drinks and energy shots among military personnel is controversial. High amounts of caffeine (the primary active ingredient in these products) may impact performance of military duties. The impact of caffeine overconsumption and potential subsequent side effects that might be experienced by service members with unique roles and responsibilities is a concern. Reported here are the prevalence of use, reasons for use, and side effects associated with consumption of energy drinks and energy shots among several populations of active duty personnel in the US military. A snowball survey was sent to over 10,000 active duty personnel. A total of 586 (∼6% response rate) individuals completed a 30-item electronic survey. Over half of respondents (53%) reported consuming an energy drink at least once in the past 30 days. One in five (19%) reported energy shot consumption in the prior 30 days. One in five (19%) also reported consuming an energy drink in combination with an alcoholic beverage. Age and gender were significantly associated with energy drink consumption. Young male respondents (18-29 years) reported the highest use of both energy drinks and energy shots. Among those reporting energy drink and energy shot use, the most common reasons for consumption were to improve mental alertness (61%) and to improve mental (29%) and physical (20%) endurance. Nearly two-thirds (65%) of users self-reported at least one side effect. The most commonly reported side effects included increased pulse rate/palpitations, restlessness, and difficulty sleeping. Use of energy products among military personnel is common and has the potential to impact warrior health and military readiness. © 2014 International Life Sciences Institute.

The Michigan Oncology Quality Consortium (MOQC) is a continuous quality improvement collaborative seeking to improve oncology care in Michigan, including for patients taking oral chemotherapy. The aim of this study was to assess the relationship between patient activation, confidence to self-manage side effects, and adherence to oral oncolytics to inform future oncology care. A multicenter cross-sectional observational study was conducted using an online survey to examine patient activation (patient activation measure, PAM), health literacy, symptom burden (Edmonton Symptom Assessment System, ESAS), confidence to self-manage side effects (fatigue, nausea, and diarrhea), and adherence to oral oncolytics. Inclusion criteria were patients taking an oral oncolytic for at least 1 month. Bivariate analyses and logistic regression were performed to evaluate relationships between the variables. A total of 125 respondents, mean (SD) age 66.2 (13.6), 57.7% female, and 95.1% Caucasian completed the survey. The mean (SD) PAM score was 65.0 (18.0). Confidence to manage fatigue, nausea, and diarrhea was associated with higher activation, and confidence to self-manage fatigue and diarrhea were associated with higher health literacy. About 30% of participants reported some level of non-adherence to oral oncolytics, and those who experienced side effects (Fisher's exact test p = 0.033) and with shorter length of therapy (t test p = 0.027) were significantly more likely to be non-adherent. These findings show that there is room for improvement across practices involved with MOQC with regard to supporting patients taking oral oncolytics. Patients will need to improve their activation levels, and oncology clinics will need to create new workflows in order to enhance self-care management ability for patients taking oral oncolytics.

The aim of this study was to compare the topical anesthetic effect of 20% benzocaine gel with 2.5% lidocaine/2.5% prilocaine (L/P) cream and gel on the pain experienced during palatal anesthetic infiltration. Two groups were studied, each containing 20 subjects. Two types of L/P mixtures were tested, an anesthetic cream (EMLA) and a thermosetting gel (Oraqix), and benzocaine was used as control. The topical agents were applied on the palatal mucosa at the canine region. A needle prick was given on each side every 2 minutes during a period of 10 minutes. The subjects recorded their findings using verbal and VAS scales. Pain scores were significantly less (P < .05) with EMLA and Oraqix than with benzocaine. Topical application of EMLA and Oraqix before palatal anesthetic infiltration is associated with less pain than with benzocaine gel.

Thirty-three patients were randomized prior to pelvic radiotherapy to receive the bile acid-sequestering resin colestipol hydrochloride, 5 grams qid, during the entire time of their therapy or diphenoxylate hydrochloride and atropine sulfate 2.5-20 mg per day (control) if they experienced diarrhea. The colestipol patients also took diphenoxylate if they had diarrhea. The patients in the colestipol group often experienced nausea, vomiting, and abdominal cramps and 8 were forced to discontinue the drug. There was no difference in the weekly stool frequency between the colestipol and the control patients but the colestipol patients who took at least 50% of the prescribedmore » dose required fewer diphenoxylate tablets than the controls. The data suggest that colestipol hydrochloride is not of value in preventing radiation-induced diarrhea because of the side effects associated with the drug, but the theory on which the use of bile acid-sequestering agents is based may be correct.« less

To investigate the side effects of 600 microg oral misoprostol given for the mother and the newborn to prevent postpartum hemorrhage (PPH). One thousand six hundred twenty women delivering at home or subcentres in rural India were randomised to receive misoprostol or placebo in the third stage of labour. Women were evaluated for shivering, fever, nausea, vomiting and diarrhea at 2 and 24 h postpartum. Newborns were evaluated within 24 h for diarrhea, vomiting and fever. Symptoms were graded as absent, mild-to-moderate or severe. Women who received misoprostol had a significantly greater incidence of shivering (52%vs. 17%, p < 0.001) and fever (4.2%vs. 1.1%, p < 0.001) at 2 h postpartum compared with women who received placebo. At 24 h, women in the misoprostol group experienced significantly more shivering (4.6%vs. 1.4%, p < 0.001) and fever (1.4%vs. 0.4%, p < 0.03). There were no differences in nausea, vomiting or diarrhea between the two groups. There were no differences in the incidence of vomiting, diarrhea or fever for newborns. Misoprostol is associated with a significant increase in postpartum maternal shivering and fever with no side effects for the newborn. Given its proven efficacy for the prevention of PPH, the benefits of misoprostol are greater than the associated risks.

2009-06-06

Premature menopause is a major concern of younger women undergoing adjuvant therapy for breast cancer. Hormone replacement therapy is contraindicated in women with a history of breast cancer. Non-hormonal medications show a range of bothersome side-effects. There is growing evidence that cognitive behavioral therapy (CBT) and physical exercise can have a positive impact on symptoms in naturally occurring menopause. The objective of this study is to investigate the efficacy of these interventions among women with breast cancer experiencing treatment-induced menopause. In a randomized, controlled, multicenter trial, we are evaluating the effectiveness of CBT/relaxation, of physical exercise and of these two program elements combined, in reducing menopausal symptoms, improving sexual functioning, reducing emotional distress, and in improving the health-related quality of life of younger breast cancer patients who experience treatment-induced menopause. 325 breast cancer patients (aged < 50) are being recruited from hospitals in the Amsterdam region, and randomly allocated to one of the three treatment groups or a 'waiting list' control group. Self-administered questionnaires are completed by the patients at baseline, and at 12 weeks (T1) and 6 months (T2) post-study entry. Upon completion of the study, women assigned to the control group will be given the choice of undergoing either the CBT or physical exercise program. Cognitive behavioral therapy and physical exercise are potentially useful treatments among women with breast cancer undergoing treatment-induced, premature menopause. For these patients, hormonal and non-hormonal therapies are contraindicated or have a range of bothersome side-effects. Hence, research into these interventions is needed, before dissemination and implementation in the current health care system can take place.

In hip-hop dance, the elements of motion that discriminate the skill levels of dancers and that influence the evaluations by judges have not been clearly identified. This study set out to extract these motion characteristics from the side-step movements of hip-hop dancing. Eight expert and eight non-expert dancers performed side-step movements, which were recorded using a motion capture system. Nine experienced judges evaluated the dancers' performances. Several parameters, including the range of motion (ROM) of the joint angles (neck, trunk, hip, knee, and face inclination) and phase delays between these angular motions were calculated. A quarter-cycle phase delay between the neck motion and other body parts, seen only in the expert dancers, is highlighted as an element that can distinguish dancers' skill levels. This feature of the expert dancers resulted in a larger ROM during the face inclination than that for the non-expert dancers. In addition, the experts exhibited a bottom-to-top segmental sequence in the horizontal direction while the non-experts did not demonstrate any such sequential motion. Of these kinematic parameters, only the ROM of the face inclination was highly correlated to the judging score and is regarded as being the most appealing element of the side-step movement.

To compare efficacy, compliance rates, and side effects of a new strapless oral interface, the Oracle, with available nasal masks over 8 weeks of use for the treatment of obstructive sleep apnea hypopnea syndrome (OSAHS). A total of 38 patients with OSAHS (respiratory disturbance index (RDI) >/=15/h) were enrolled after the diagnostic polysomnogram for subsequent continuous positive airway pressure (CPAP) therapy. After randomization, therapeutic pressures during a titration study were determined for 21 patients in the oral group and 17 patients in the nasal group. Comparisons for nasal and oral interfaces were made for baseline patient characteristics, average hours of CPAP use, side effects from therapy, and among questionnaires evaluating patients' subjective responses to therapy at months 1 and 2. No significant difference was observed in the average hours of CPAP use between the oral (4.5+/-2.1; 5.5+/-2.6) and nasal groups (4.0+/-2.6; 4.8+/-2.5) for either month 1 or 2 (P>0.05). The dropout rates were similar for both groups after 8 weeks of therapy. However, patients in the nasal group had higher occurrences of side effects such as nasal congestion, dryness, and air leaks, whereas patients in the oral group experienced more oral dryness and gum pain. Oral delivery of CPAP with the Oracle is an effective and suitable alternative for patients with OSAHS.

The aim of this study was to investigate the efficacy and side effects of botulinum toxin (BTX) in the treatment of hemifacial spasm (HFS). We also focused on the divergence between different injection techniques and commercial forms. We retrospectively evaluated 470 sessions of BTX injections administered to 68 patients with HFS. The initial time of improvement, duration and degree of improvement, and frequency and duration of adverse effects were analysed. Pretarsal and preseptal injections and Botox (Allergan, Irvine, CA, USA) and Dysport (Ipsen Biopharmaceuticals, Paris, France) brands were compared in terms of efficacy and side effects, accompanied by a review of papers which reported BTX treatment of HFS. An average of 34.5 units was used per patient. The first improvement was felt after 8 days and lasted for 14.8 weeks. Patients experienced a 73.7% improvement. In 79.7% of injections, no adverse effect was reported, in 4.9% erythema, ecchymosis, and swelling in the injection area, in 3.6% facial asymmetry, in 3.4% ptosis, in 3.2% diplopia, and in 2.3% difficulty of eye closure was detected. Patients reported 75% improvement on average after 314 sessions of pretarsal injections and 72.7% improvement after 156 sessions of preseptal injections (p=0.001). The efficacy and side effects of Botox and Dysport were similar. BTX is an effective and safe treatment option for HFS. No difference was determined between Botox and Dysport, and pretarsal injection is better than preseptal injection regarding the reported degree of improvement. Copyright © 2015 Elsevier Ltd.

Unsatisfactory Helicobacter pylori eradication rates and therapy-associated side effects remain a problem. To update our 2010 meta-analysis on the effects of Saccharomyces boulardii as supplementation to a standard eradication regimen on H. pylori eradication rates and therapy-associated side effects. The Cochrane Library, MEDLINE and EMBASE databases were searched from July 2010 (end date of last search) to February 2015, with no language restrictions, for randomised controlled trials (RCTs); additional references were obtained from reviewed articles. Quality of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) guidelines. Eleven RCTs (2200 participants, among them 330 children) met the inclusion criteria. Of the 853 patients in the S. boulardii group, 679 (80%, 95% CI 77-82) experienced eradication compared with 608 of the 855 patients (71%, 95% CI 68-74) in the control group [relative risk (RR) 1.11, 95% confidence interval (CI) 1.06-1.17; moderate quality evidence]. S. boulardii compared with control reduced the risk of overall H. pylori therapy-related adverse effects (RR 0.44, 95% CI 0.31-0.64; moderate quality evidence), particularly of diarrhoea (RR 0.51, 95% CI 0.42-0.62; high quality evidence) and nausea [RR 0.6, 95% CI 0.44-0.83 (moderate quality of evidence)]. In the populations studied, the effectiveness of standard triple therapy was unsatisfactory. The addition of S. boulardii significantly increased the eradication rate, but it was still below the desired level of success. Saccharomyces boulardii significantly decreased some therapy-related side effects. © 2015 John Wiley & Sons Ltd.

To summarise all clinical data on the contraceptive efficacy and bleeding profile associated with an oestradiol valerate (E2V) and dienogest (DNG) [E2V/DNG] combined oral contraceptive (COC) derived from Phase III trials. Pooled analysis of three large-scale multicentre trials conducted in healthy women who received oral E2V/DNG for 7 to 28 cycles (28-day cycles). A total of 2266 women were included in this analysis. Overall, 19 pregnancies occurred over 13 cycles during 880,950 days of relevant exposure (Pearl Index [PI] of 0.79; upper limit of the two-sided 95% confidence interval [CI]: 1.23). Ten pregnancies attributed to method failure came about during 871,091 days of relevant exposure (adjusted PI of 0.42; upper limit of the two-sided 95% CI: 0.77). In women aged 18 to 35 years (n = 1687), the corresponding PI and adjusted PI were 1.01 (upper limit of the two-sided 95% CI: 1.59) and 0.51 (upper limit of the two-sided 95% CI: 0.97), respectively. In the first 13 cycles of treatment, 76 to 81% of women experienced scheduled withdrawal bleeding, and 13 to 23% experienced intracyclic bleeding. E2V/DNG provides reliable contraceptive efficacy in women aged 18 to 50 years.

Sided functions of an arginine-agmatine antiporter oriented in liposomes.

PubMed

Tsai, Ming-Feng; Fang, Yiling; Miller, Christopher

2012-02-28

The arginine-dependent extreme acid resistance system helps enteric bacteria survive the harsh gastric environment. At the center of this multiprotein system is an arginine-agmatine antiporter, AdiC. To maintain cytoplasmic pH, AdiC imports arginine and exports its decarboxylated product, agmatine, resulting in a net extrusion of one "virtual proton" in each turnover. The random orientation of AdiC in reconstituted liposomes throws up an obstacle to quantifying its transport mechanism. To overcome this problem, we introduced a mutation, S26C, near the substrate-binding site. This mutant exhibits substrate recognition and pH-dependent activity similar to those of the wild-type protein but loses function completely upon reaction with thiol reagents. The membrane-impermeant MTSES reagent can then be used as a cleanly sided inhibitor to silence those S26C-AdiC proteins whose extracellular portion projects from the external side of the liposome. Alternatively, the membrane-permeant MTSEA and membrane-impermeant reducing reagent, TCEP, can be used together to inhibit proteins in the opposite orientation. This approach allows steady-state kinetic analysis of AdiC in a sided fashion. Arginine and agmatine have similar Michaelis-Menten parameters for both sides of the protein, while the extracellular side selects arginine over argininamide, a mimic of the carboxylate-protonated form of arginine, more effectively than does the cytoplasmic side. Moreover, the two sides of AdiC have different pH sensitivities. AdiC activity increases to a plateau at pH 4 as the extracellular side is acidified, while the cytoplasmic side shows an optimal pH of 5.5, with further acidification inhibiting transport. This oriented system allows more precise analysis of AdiC-mediated substrate transport than has been previously available and permits comparison to the situation experienced by the bacterial membrane under acid stress.

Oral oxybutynin for treating hyperhidrosis is effective and safe. Its side-effects are mild but frequent so we consider whether transdermal oxybutynin (considered to have a better side-effect profile) could be an alternative for treating hyperhidrosis. During 2015, a prospective study was conducted. Epidemiological variables, effectiveness (using the Hyperhidrosis Disease Severity Scale) and tolerance to transdermal oxybutynin were compiled concerning two different groups (patients previously treated or untreated with oral oxybutynin), at baseline, and at 3 and 12 months. Seven previously treated and six previously untreated patients were included. Five patients in the first group discontinued the treatment within 3 months. Of the two remaining patients, one reported ineffectiveness and the other obtained an excellent response but discontinued due to local irritation. Among the untreated patients, two showed no response and four experienced improvement (three with "partial response" and one with "excellent response"). All patients discontinued treatment within 12 months. No major adverse effects were observed. The absence of active metabolites after transdermal oxybutynin could result in less effectiveness than oral oxybutynin, although it is usually well tolerated. In conclusion, transdermal oxybutynin could have low effectiveness for the treatment of hyperhidrosis in patients following intolerance to oral oxybutynin but could provide good results in patients who have never tried systemic drugs. © 2017 Japanese Dermatological Association.

There is no universally accepted and effective prophylaxis of migraine headache episodes. Thus we aimed to investigate the effects of Lippia alba (Mill.) N. E. Brown, an herb with many effects on central nervous system, on pain frequency and intensity of migraine patients. Patients were enrolled in a prospective, phase 2, non-controlled cohort study to orally receive hydro-alcoholic extract of L. alba leaves. Headache intensity and frequency of episodes were recorded before and after 30-60 days of treatment. We also studied the chemical composition of its essential oil by gas chromatography-mass spectrometry. We described for the first time a particular L. alba chemotype with geranial and carvenone as major compounds. With treatment, both frequency and intensity of pain episodes significantly decreased from baseline to first reassessment date. More than 80% of patients experienced a minimum 50% reduction on pain intensity and frequency. No side effects were reported. Treatment with a geranial plus carvenone chemotype of L. alba hydro-alcoholic extract is a cheap, widely available, highly effective therapy to reduce both the intensity and the frequency of headache episodes of migraine patients with no side effects.

Bumblebees measure optic flow for position and speed control flexibly within the frontal visual field.

PubMed

Linander, Nellie; Dacke, Marie; Baird, Emily

2015-04-01

When flying through narrow spaces, insects control their position by balancing the magnitude of apparent image motion (optic flow) experienced in each eye and their speed by holding this value about a desired set point. Previously, it has been shown that when bumblebees encounter sudden changes in the proximity to nearby surfaces - as indicated by a change in the magnitude of optic flow on each side of the visual field - they adjust their flight speed well before the change, suggesting that they measure optic flow for speed control at low visual angles in the frontal visual field. Here, we investigated the effect that sudden changes in the magnitude of translational optic flow have on both position and speed control in bumblebees if these changes are asymmetrical; that is, if they occur only on one side of the visual field. Our results reveal that the visual region over which bumblebees respond to optic flow cues for flight control is not dictated by a set viewing angle. Instead, bumblebees appear to use the maximum magnitude of translational optic flow experienced in the frontal visual field. This strategy ensures that bumblebees use the translational optic flow generated by the nearest obstacles - that is, those with which they have the highest risk of colliding - to control flight. © 2015.

Oral diazepam, administered in varying doses, is among the few proposed treatment options for electrical status epilepticus during slow wave sleep in children. We sought to retrospectively evaluate the long-term efficacy of high-dose oral diazepam in reducing electrographic and clinical evidence of electrical status epilepticus during slow wave sleep in children. Additionally, we surveyed caregivers to assess safety and behavioral outcomes related to ongoing therapy. We collected demographic and clinical data on children treated for electrical status epilepticus during slow wave sleep between October 2010 and March 2013. We sought to identify the number of patients who achieved at least a 50% reduction in spike wave index on electroencephalograph after receiving high-dose oral diazepam. We also administered a questionnaire to caregivers to assess for behavioral problems and side effects. We identified 42 evaluable patients who received high-dose diazepam (range 0.23-2.02 mg/kg per day) to treat electrical status epilepticus during slow wave sleep. Twenty-six patients had spike reduction data and 18/26 (69.2%) children achieved a greater than 50% reduction in spike wave count from an average of 15.54 to 5.05 (P = 0.001). We received 28 responses to the questionnaire. Some patients experienced new onset of difficulties with problem-solving and speech and writing development. Sleep disturbances (50%) and irritability (57.1%) were the most frequent side effects reported. There did not appear to be a dose-related effect with electroencephalograph changes, behavioral effects, or side effects. High-dose oral diazepam significantly reduces the spike wave count on electroencephalograph in children with electrical status epilepticus during slow wave sleep. Although this therapy improves electroencephalograph-related findings, it can be associated with concerning neurological and behavioral side effects in some individuals, so further study is warranted.

Numerous traditional methods are used in the treatment of infertility around the world. To identify the traditional practices of infertile women using one clinic in Ankara, Turkey. The population comprised all women (5700) who attended one infertility outpatient clinic in 2007. The sample was calculated using sample calculation formula and 410 women were included in the study. The survey method was used for data collection. Of the responding women, 27.3% had tried a traditional practice, and 67.8% who tried traditional practices used an herbal mixture. The reason for the women's use of a traditional practice was 'hope' (66.9%), and 15.2% of them had experienced an adverse effect related with traditional practice. Maternal education level, perceived economic status, duration of marriage all significantly affected the use of traditional practices (P<0.05). The women who had received unsuccessful medical treatment for infertility and who had experienced side effects after medical treatment had a higher rate of use of traditional practice (P<0.05). Almost one in three of the women who responded to the questionnaire had tried traditional methods, and some experienced adverse effects related to the practice. For couples with infertility problems, educational programmes and consultation services should be organized with respect to their traditional culture. Women should be informed about the hazards of traditional practices and avoidance of harmful practices, and continuous emotional support must be provided for infertile couples. In the future, nursing staff should play a much larger role in these supportive services.

Bullous dermatosis associated with vancomycin extravasation.

Bohm, Nicole M; Wong, Jeffrey G

2012-02-01

Cutaneous side effects related to vancomycin therapy have been reported including histamine-related reactions, linear IgA bullous dermatosis, Stevens-Johnson syndrome, maculopapular rash and drug rash with eosinophilia and systemic symptoms. In all instances, these reports were due to the systemic administration of vancomycin and subsequent immunological reactions to the medication. Drug extravasation into soft tissues can result in a variety of clinical outcomes usually related to physiochemical properties of the drug extravasated and its diluents or pharmacologic effects on the vasculature and tissue. The authors report a patient who experienced vancomycin extravasation that resulted in a localized bullous eruption resembling linear IgA bullous dermatosis, a phenomenon not previously described in the literature.

The authors report a case of a 68-year-old Caucasian female with type 2 diabetes mellitus who experienced an acute exacerbation of her rosacea 2 weeks after self-initiating cinnamon oil pills to lower her blood sugar levels. Historically, cinnamon oil has been used for a variety of medicinal purposes, but recently the use of cinnamon oil in lowering blood glucose and cholesterol levels in patients with type 2 diabetes is being investigated and gaining popularity amongst the general population. The use of cinnamon has commonly produced cutaneous side effects of irritant or allergic contact dermatitis and been reported to have vasodilatory effects. Yet, there are no reports of cinnamon use triggering a rosacea exacerbation in the literature.

Assessing cost-effectiveness of drug interventions for schizophrenia.

Magnus, Anne; Carr, Vaughan; Mihalopoulos, Cathrine; Carter, Rob; Vos, Theo

2005-01-01

To assess from a health sector perspective the incremental cost-effectiveness of eight drug treatment scenarios for established schizophrenia. Using a standardized methodology, costs and outcomes are modelled over the lifetime of prevalent cases of schizophrenia in Australia in 2000. A two-stage approach to assessment of health benefit is used. The first stage involves a quantitative analysis based on disability-adjusted life years (DALYs) averted, using best available evidence. The robustness of results is tested using probabilistic uncertainty analysis. The second stage involves application of 'second filter' criteria (equity, strength of evidence, feasibility and acceptability) to allow broader concepts of benefit to be considered. Replacing oral typicals with risperidone or olanzapine has an incremental cost-effectiveness ratio (ICER) of 48,000 Australian dollars and 92,000 Australian dollars/DALY respectively. Switching from low-dose typicals to risperidone has an ICER of 80,000 Australian dollars. Giving risperidone to people experiencing side-effects on typicals is more cost-effective at 20,000 Australian dollars. Giving clozapine to people taking typicals, with the worst course of the disorder and either little or clear deterioration, is cost-effective at 42,000 Australian dollars or 23,000 Australian dollars/DALY respectively. The least cost-effective intervention is to replace risperidone with olanzapine at 160,000 Australian dollars/DALY. Based on an 50,000 Australian dollars/DALY threshold, low-dose typical neuroleptics are indicated as the treatment of choice for established schizophrenia, with risperidone being reserved for those experiencing moderate to severe side-effects on typicals. The more expensive olanzapine should only be prescribed when risperidone is not clinically indicated. The high cost of risperidone and olanzapine relative to modest health gains underlie this conclusion. Earlier introduction of clozapine however, would be cost-effective. This work is limited by weaknesses in trials (lack of long-term efficacy data, quality of life and consumer satisfaction evidence) and the translation of effect size into a DALY change. Some stakeholders, including SANE Australia, argue the modest health gains reported in the literature do not adequately reflect perceptions by patients, clinicians and carers, of improved quality of life with these atypicals.

Efficacy and safety of fluconazole in the treatment of systemic fungal infections in pediatric patients. Multicentre Study Group.

Presterl, E; Graninger, W

1994-04-01

In a non-comparative multicentre trial 51 patients aged 24 days to 17 years received treatment with intravenous or oral fluconazole for suspected systemic fungal infections. Twenty-seven patients had confirmed infections, 26 being confirmed mycologically and 1 histologically. All isolates were Candida species. Of the 43 clinically assessed patients, 30 were considered cured, 7 improved and 6 experienced failure of therapy. Of 27 patients with confirmed fungal infections, 25 were assessed mycologically and all but one were considered cured. Of the six patients experiencing clinical failure, two had a confirmed infection and only one of these experienced mycological failure. This patient had a primary diagnosis of candidemia with persistence of Candida albicans and Candida parapsilosis. All 51 patients were evaluable for safety. No treatment-related adverse events required termination of treatment. Treatment-related side effects (diarrhea, vomiting, deafness) were reported by three of 51 patients, three patients had laboratory test abnormalities possibly related to fluconazole treatment, including elevation of liver enzyme levels and of the eosinophil count. Results of this study confirm the efficacy and safety of fluconazole in the treatment of pediatric patients with severe fungal infection.

Oxybutynin for treating hyperhidrosis in children has been evaluated only in short-term studies. We aimed to investigate the long-term effects of oxybutynin in treating children with palmar and plantar hyperhidrosis who had not undergone surgery and who were monitored for at least 6 months (median 19.6 mos). A cohort of 97 patients was evaluated retrospectively, with particular attention to 59 children (ages 4-14 yrs) who were treated for longer than 6 months. Their quality of life (QOL) was evaluated using a validated clinical questionnaire before and after 6 weeks of pharmacologic therapy. A self-assessment of hyperhidrosis was performed after 6 weeks and after the last consultation. By their final office visit, more than 91% of the children with hyperhidrosis treated with oxybutynin experienced moderate or great improvement in their level of sweating and 94.9% experienced improvement in QOL. More than 90% of children reported improvement of hyperhidrosis at other sites. Dry mouth was the most common side effect. Oxybutynin appears to be an effective treatment option for children with hyperhidrosis, and positive results are maintained over the long term (median 19.6 mos). © 2014 Wiley Periodicals, Inc.

Localized periorbital edema induced by Ibuprofen.

2005-12-01

We documented localized periorbital edema in one patient with ibuprofen sensitivity without underlying chronic urticaria. The reaction developed one hour after ingestion of 200 mg of ibuprofen. No systemic symptoms were observed. No other NSAIDs did not induce symptoms. This patient was able to tolerate doses of ibuprofen after pretreatment with terfenadine. These observations suggest that histamine played a central role in this ibuprofen-induced skin reaction. Treatment with terfenadine enabled the patient to tolerate ibuprofen without experiencing any side effects. To the best of our knowledge, this is the first reported case of periorbital edema induced by ibuprofen.

Tyrosine kinase inhibitors are standard treatment in patients with metastatic renal cell carcinoma (mRCC). Several studies have indicated that side-effects including hypothyroidism may serve as potential predictive biomarkers of treatment efficacy. All patients with clear cell mRCC treated with sunitinib in the first-line setting in our Center between November 2008 and October 2013 were included. Thyroid function was assessed after every 2 cycles. Prognostic factors were tested using Cox proportional hazards model for univariate analysis. During treatment, 29.3% developed hypothyroidism, with a median of peak TSH values of 34.4 mIU/L. Patients who had both TSH >4 mIU/L and were receiving substitution therapy with levothyroxine had prolonged PFS compared to all other patients (25.3 months vs. 9.0 months; p=0.042). The rate of hypothyroidism as a side-effect of sunitinib in patients with mRCC is significant. Patients with symptomatic hypothyroidism experienced significantly longer PFS, but without difference in OS. Copyright© 2014 International Institute of Anticancer Research (Dr. John G.

Latest advances in novel cannabinoid CB2 ligands for drug abuse and their therapeutic potential

PubMed Central

Yang, Peng; Wang, Lirong; Xie, Xiang-Qun

2012-01-01

The field of cannabinoid (CB) drug research is experiencing a challenge as the CB1 antagonist Rimonabant, launched in 2006 as an anorectic/anti-obesity drug, was withdrawn from the European market due to the complications of suicide and depression as side effects. There is interest in developing CB2 drugs without CB1 psychotropic side effects for drug-abuse treatment and therapeutic medication. The CB1 receptor was discovered predominantly in the brain, whereas the CB2 is mainly expressed in peripheral cells and tissues, and is involved in immune signal transduction. Conversely, the CB2 receptor was recently detected in the CNS, for example, in the microglial cells and the neurons. While the CB2 neurons activity remains controversial, the CB2 receptor is an attractive therapeutic target for neuropathic pain, immune system, cancer and osteoporosis without psychoactivity. This review addresses CB drug abuse and therapeutic potential with a focus on the most recent advances on new CB2 ligands from the literature as well as patents. PMID:22300098

Adverse breast cancer treatment effects: the economic case for making rehabilitative programs standard of care.

Schmitz, Kathryn H; DiSipio, Tracey; Gordon, Louisa G; Hayes, Sandra C

2015-06-01

The purpose of this work was to evaluate the patient-borne financial cost of common, adverse breast cancer treatment-associated effects, comparing cost across women with or without these side effects. Two hundred eighty-seven Australian women diagnosed with early-stage breast cancer were prospectively followed starting at 6 months post-surgery for 12 months, with three monthly assessments of detailed treatment-related side effects and their direct and indirect patient costs attributable to breast cancer. Bootstrapping statistics were used to analyze cost data, and adjusted logistic regression was used to evaluate the association between costs and adverse events from breast cancer. Costs were inflated and converted from 2002 Australian to 2014 US dollars. More than 90 % of women experienced at least one adverse effect (i.e., post-surgical issue, reaction to radiotherapy, upper-body symptoms or reduced function, lymphedema, fatigue, or weight gain). On average, women paid $5,636 (95 % confidence interval (CI), $4,694, $6,577) in total costs. Women with any one of the following symptoms (fatigue, reduced upper-body function, upper-body symptoms) or women who report ≥4 adverse treatment-related effects, have 1.5 to nearly 4 times the odds of having higher healthcare costs than women who do not report these complaints (p < 0.05). Women face substantial economic burden due to a range of treatment-related health problems, which may persist beyond the treatment period. Improving breast cancer care by incorporating prospective surveillance of treatment-related side effects and strategies for prevention and treatment of concerns (e.g., exercise) has real potential for reducing patient-borne costs.

Guanidinoacetic acid (GAA) is a natural precursor of creatine, yet the potential use of GAA as a nutritional additive for restoring creatine availability in humans has been limited by unclear efficacy and safety after exogenous GAA administration. The present study evaluated the effects of orally administered GAA on serum and urinary GAA, creatine and creatinine concentration, and on the occurrence of adverse events in healthy humans. Twenty-four healthy volunteers were randomized in a double-blind design to receive either GAA (2.4 grams daily) or placebo (PLA) by oral administration for 6 weeks. www.clinicaltrials.gov, identification number NCT01133899. Serum creatine and creatinine increased significantly from before to after administration in GAA-supplemented participants (P < 0.05). The proportion of participants who reported minor side effects was 58.3% in the GAA group and 45.5% in the placebo group (P = 0.68). A few participants experienced serum creatine levels above 70 µmol/L. Exogenous GAA is metabolized to creatine, resulting in a significant increase of fasting serum creatine after intervention. GAA had an acceptable side-effects profile with a low incidence of biochemical abnormalities.

To report the use of Augmentin Duo 400/57 (GlaxoSmithKline, Middlesex, UK) in the treatment of childhood blepharokeratoconjunctivitis (BKC). This is a retrospective interventional case series. The case notes of 7 consecutive patients treated with Augmentin Duo 400/57 for BKC during 18 months were reviewed. Diagnostic criteria for BKC were blepharitis including recurrent chalazia and meibomian gland dysfunction, eyelid margin telangiectasia and facial rosacea, recurrent episodes of chronic red eye, photophobia, watering, punctate superficial keratopathy, corneal neovascularization, and corneal ulcers. Seven children (age range: 6 to 14 years) were diagnosed as having BKC. All children received systemic Augmentin Duo 400/57 and showed considerable improvement within the first month of therapy. Six children had no recurrences during a mean follow-up of 6 months. No patients experienced any side effects from this treatment. Augmentin Duo 400/57 has not previously been reported in the treatment of BKC in children. In this case series, Augmentin Duo 400/57 proved to be at least as effective as current treatments with systemic erythromycin or doxycycline with the advantage of a twice-daily dosage and a superior side-effect profile.

In the early 1970s the effort was begun to examine the clinical benefits of "menstrual induction" (MI) at 6 weeks pregnancy (last menstrual period), in the belief that if pregnancy is to be terminated there was no sound medical nor psychological reason to delay the procedure. It was found that the transcervical, intrauterine delivery of a "PG-impact" compromised the conceptus and terminated pregnancy in 95% of the cases, with clinical symptoms of menstruation rather than abortion. The side-effects were acceptable; the prematurity rate did not increase in subsequent pregnancies. Yet, the need for strict asepsis limited the use of this otherwise simple and effective procedure. Recently, this limitation has been overcome by the development of the PGE2 analogue 16-phenoxy-w17,18,19,20 tetranor-PGE2-methyl sulfanylamide ('Sulproston'). Clinical trials have been done in terms of dealing with the questions of efficacy, acceptability, and preference. 90 volunteers have been studied. At 14 days follow-up the success rate (negative pregnancy test) was 96%. The side effects were acceptable -- vomiting 26%, diarrhea 10%, and endometritis 2%. Of the 42 patients interviewed, 90% were satisfied with the procedure. Of those who had previously experienced surgical interruption, 89% preferred this pharmacological method.

Prescription medication use increases with age. Seniors face an increased risk of adverse drug reactions from medications, partly because the kidneys and liver can lose functional ability with increasing age, resulting in the need for changes in dosage. To use population survey data to understand the extent and impact of multiple medication use and adverse drug events among Canadian seniors. This study consists of analysis of data from the Canadian Survey of Experiences with Primary Health Care, which was conducted through telephone by Statistics Canada in 2008. These analyses focussed on the 3132 respondents who were ≥ 65 years of age. Twenty-seven per cent of seniors reported taking five or more medications on a regular basis. Within the past year, 12% of seniors taking five or more medications experienced a side effect that required medical attention compared with 5% of seniors taking only one or two medications. Even when controlling for age and number of chronic conditions, the number of prescription medications was associated with the rate of emergency department use. Less than half of all seniors reported having received medication reviews and having the possible side effects of their prescription medications explained to them by their physician. Many Canadian seniors have an elevated risk of adverse events due to taking a high number of prescription medications and not having the potential side effects and drug interactions explained to them. There are interventions that can potentially reduce polypharmacy and adverse events, including routine medication reviews.

Background The aim of the present prospective observational study was to assess the tolerability and antihyperglycemic efficacy of metformin extended-release (MXR) in the routine treatment of patients with type 2 diabetes mellitus (T2DM) from six Asian countries. Methods Data from 3556 patients treated with once-daily MXR for 12 weeks, or until discontinuation, were analyzed. Results Treatment with MXR was well tolerated, with 97.4% of patients completing 12 weeks of treatment. Only 3.3% of patients experienced one or more gastrointestinal (GI) side-effects and only 0.7% of patients discontinued for this reason (primary endpoint). The incidence of GI side-effects and related discontinuations appeared to be considerably lower during short-term MXR therapy than during previous treatment (mean 2.71 years’ duration), most commonly with immediate-release metformin. A 12-week course of MXR therapy also reduced HbA1c and fasting glucose levels from baseline. Conclusions The present study provides new insights into the incidence of GI side-effects with MXR in Asian patients with T2DM and on the tolerability of MXR in non-Caucasian populations. Specifically, these data indicate that once-daily MXR not only improves measures of glycemic control in Asian patients with T2DM, but also has a favorable GI tolerability profile that may help promote enhanced adherence to oral antidiabetic therapy.

Six habits of merely effective negotiators.

PubMed

Sebenius, J K

2001-04-01

Most executives know the basics of negotiation; some are spectacularly adept. Yet even experienced negotiators routinely leave money on the table, end up in deadlock, damage relationships, or allow conflicts to spiral. They fall prey to common mistakes that keep them from solving the right negotiation problem. In any negotiation, each side ultimately chooses between two options: accepting a deal or taking its best no-deal option--that is, the course of action if a deal were not possible. As a negotiator, you seek to advance your interests by persuading the other side to say yes to a proposal that meets your interests better than your best no-deal option. Because the other side will say yes only to a proposal that meets its own interests better than its best no-deal option, you must understand and shape your counterpart's decision so that it chooses in its own interest what you want. Far from being exercises in manipulation, understanding your counterpart's interests and shaping the decision so that the other side agrees to a proposal for its own reasons are the keys to jointly creating and claiming sustainable value from a negotiation. In this article, James Sebenius compares good negotiating practice with bad, providing examples from the business world and insights from 50 years of research and analysis on negotiation. The author describes six common mistakes that result in merely effective negotiation: neglecting your counterpart's problem, letting price bulldoze other interests, letting positions drive out interests, searching too hard for common ground, neglecting no-deal alternatives, and failing to correct for skewed vision.

Statement of the Problem Treatment with salivary substitutes and stimulation of salivary flow by either mechanical or pharmacologic methods has side effects and only provides symptomatic relief but no long-lasting results. Purpose To assess the effectiveness of extraoral transcutaneous electric nerve stimulation (TENS) as a mean of stimulating salivary function in healthy adult subjects; as well as to determine the gender and age-dependent changes in salivary flow rates of unstimulated and stimulated parotid saliva. Materials and Method Hundred patients were divided into two groups; Group I aged 20-40 and Group II aged ≥ 60 years. The TENS electrode pads were externally placed on the skin overlying the parotid glands. Unstimulated and stimulated parotid saliva was collected for 5 minutes each by using standardized collection techniques. Results Eighty seven of 100 subjects demonstrated increased salivary flow when stimulated via the TENS unit. Ten experienced no increase and 3 experienced a decrease. The mean unstimulated salivary flow rate was 0.01872 ml/min in Group I and 0.0088 ml/min in Group II. The mean stimulated salivary flow rate was 0.03084 ml/min (SD= 0.01248) in Group I, and 0.01556 ml/min (SD 0.0101) in Group II. After stimulation, the amount of salivary flow increased significantly in both groups (p< 0.001). Statistical comparison of the two groups revealed them to be significantly different (p< 0.001), with Group I producing more saliva. Gender-wise, no statistically significant difference was seen among the subjects in Group I (p = 0.148), and those in Group II (p= 0.448). Out of 12 subjects with 0 baseline flows, 7 continued to have no flow. Five subjects observed side effects, although minimal and transient. Conclusion The TENS unit was effective in increasing parotid gland salivary flow in healthy subjects. There was age-related but no gender-related variability in parotid salivary flow rate.

Episodic memory for spatial context biases spatial attention.

The study explores the bottom-up attentional consequences of episodic memory retrieval. Individuals studied words (Experiment 1) or pictures (Experiment 2) presented on the left or on the right of the screen. They then viewed studied and new stimuli in the centre of the screen. One-second after the appearance of each stimulus, participants had to respond to a dot presented on the left or on the right of the screen. The dot could follow a stimulus that had been presented, during the study phase, on the same side as the dot (congruent condition), a stimulus that had been presented on the opposite side (incongruent condition), or a new stimulus (neutral condition). Subjects were faster to respond to the dot in the congruent compared to the incongruent condition, with an overall right visual field advantage in Experiment 1. The memory-driven facilitation effect correlated with subjects' re-experiencing of the encoding context (R responses; Experiment 1), but not with their explicit memory for the side of items' presentation (source memory; Experiment 2). The results indicate that memory contents are attended automatically and can bias the deployment of attention. The degree to which memory and attention interact appears related to subjective but not objective indicators of memory strength.

Background/objectives The COSMOS study was a phase 2a clinical trial that showed high cure rates of genotype 1 chronic hepatitis C (CHC) and a favorable side effect profile using a 12-week regimen of simeprevir + sofosbuvir (SIM + SOF). Given the small number of patients treated with the SIM + SOF regimen in the COSMOS trial, there is uncertainty regarding the efficacy and safety of this combination therapy. We now report our experience with the COSMOS regimen in the multiethnic population of Hawaii, including patients of East Asian ancestry and with decompensated cirrhosis. Methods This study is a retrospective review of 138 patients treated with a fixed dose regimen of SIM 150 mg and SOF 400 mg daily at a single referral center. We collected data on demographics, side effects, laboratory studies and sustained virological response (SVR). Statistical analysis was performed with Stata v8.2 software. Results Baseline characteristics of the 138 patients initiated with SIM + SOF therapy were: 68.8 % cirrhotic (22.1 % of those Child-Pugh Class B), 37 % Asian, 11.6 % Pacific Islander, 63 % male, mean age 61.3 ± 7.8 years, mean BMI 27.8 ± 6.1 kg/m2, 26.8 % diabetic, 63.8 % genotype 1a, 44.9 % previously treatment experienced. A total of 100 % of patients that completed therapy (n = 137) had undetectable viral loads at end of treatment (EOT). Twelve patients relapsed post-treatment resulting in an overall 12 week SVR (SVR12) rate of 89.1 %. 95 % of decompensated cirrhotic patients achieved SVR12, compared to 85.3 % of compensated cirrhotic patients and 93 % of non-cirrhotic patients. 92 % of Asian patients achieved SVR12 compared to 87.5 % in non-Asian patients. There were no statistically significant differences in SVR12 between treatment naive and treatment experienced patients (86.8 vs 91.9 %). 87.5 % of post-transplant patients achieved SVR12. The main side effects were headache 16.2 %, fatigue 24.2 %, pruritis 14.1 %; none were >grade 2 in severity. There were no differences in side effect profiles of patients with decompensated cirrhosis. Pruritis only was statistically significant between Asians and non-Asians (22 vs 5.7 %). Trends toward improvement in platelet counts and total bilirubin were noted at 12-weeks post treatment, while improvement in albumin in cirrhotic patients reached statistical significance (3.77–4.01 mg/dL, p = 0.0108). Conclusions The 12-week fixed dose course of SIM + SOF was well tolerated in a multiethnic population of primarily cirrhotic patients, including those with decompensated disease. This real world trial achieved SVR12 rates comparable to the COSMOS data. Higher incidence of adverse side effects was not observed with an exception of higher rate of pruritis in Asians. The increase in albumin in cirrhotic patients was statistically significant and suggested early improvement in synthetic function following viral eradication. Higher BMI (≥30 kg/m2) was the only factor that correlated with post-treatment relapse by multivariate analysis. PMID:27026431

Protection of children in Child Safety Seats (CSS) in side impact crashes has been a topic of recent studies. The objective of this study was to evaluate the performance of CSS in far-side impacts through a series of sled tests conducted at varying test speeds. Forty eight sled tests were conducted at three speeds (24 km/h, 29 km/h and 36 km/h), under two different CSS attachment conditions (LATCH and seat belt attached), using rear facing and forward facing CSS from four different manufacturers. Analyses were conducted to examine head retention within the CSS, velocity of the head as it passes an imaginary plane (cross over into other occupant space or door), lateral trajectory of the head and knee; head, chest and pelvis accelerations; neck and lumbar loads and moments. In addition to these parameters, the CSS were visually inspected for structural integrity after each test. Results from these sled tests highlighted the differential performance of CSS in far-side impacts. During the tests, all CSS experienced significant lateral movement irrespective of attachment type. In rear facing CSS tests, one of the designs failed as the seat disengaged from its base. In forward facing CSS tests, it was observed that the seat belt attached CSS experienced less rotational motion than the LATCH attached CSS. ATD head retention within the seat was not achieved with either CSS attachments at any speed. The findings from this study augment the current efforts to define regulatory sled setup procedure for far-side impact crashes involving children in CSS, which currently does not exist and will eventually further the protection of children in automobiles.

Hypnosis is recognised in medicine as an effective complementary therapy. However, few qualitative data are available concerning the benefits it may bring. This qualitative exploratory study aimed to examine the contribution of hypnosis to the care of advanced cancer patients. Results demonstrate that hypnosis is an effective and efficient means of developing the resources of people suffering from serious illness. After an average of four hypnotherapy sessions, patients said they were able to locate previously unexploited resources within themselves and were able to become autonomous in the use of self-hypnosis. The major benefit reported concerned a reduction in anxiety. For patients experiencing anxiety about death, hypnosis allowed them, within a therapeutic environment perceived as safe, to explore different facets of their fears and to develop adaptive strategies. Aside from slight fatigue experienced during the sessions, no adverse side-effects were reported. In conclusion, this study exploring the effects of hypnosis allowed us to identify important benefits for patients suffering from advanced cancer. Consequently, replication on a larger scale is recommended in order to ascertain the extent to which it is possible to generalise from these results and in order better to define the characteristics of patients most likely to benefit from this therapy.

To report the 10-year experience of a single center in treating patients with refractory inflammatory bowel disease (IBD) with relatively lower dose of 6-mercaptopurine (6-MP). The charts of 285 patients with IBD (Crohn's disease 160 and ulcerative colitis 125) receiving 6-MP were reviewed. Clinical response, subsequent breakthrough while taking 6-MP, and relapse rates when 6-MP was discontinued and side effects were assessed. Ninety-three percent of the patients were taking 50 to 75 mg/day of 6-MP. Complete remission was achieved in 62%, partial remission in 14.5%, and failure to achieve remission in 23.5% of the patients. Of complete responders, 27.5% had breakthrough while continuing 6-MP. Nine percent of those that achieved a complete remission experienced a relapse after 6-MP was discontinued. Side effects included leukopenia (11.2%), abnormal liver function tests (3.8%), various infections, including pneumonia (3.1%), pancreatitis (2.5%), nausea (2.1%), headache (2.8%), fever (1.4%), hair loss (1%), and rash (0.7%). Two cancers occurred while taking 6-MP: melanoma on the finger and a fatal colonic lymphoma. Four patients continued 6-MP throughout pregnancies and had normal outcomes. In our experience 6-MP is relatively safe and appears to be as effective at a lower dosage (0.84 mg/kg per day) compared with the recommended higher dosage (1-1.5 mg/kg per day), when leukopenia was more frequent. Serious side effects, although rare, need to be monitored.

Almost half of all pregnancies in the United States are unintentional, unplanned, or mistimed. Most unplanned pregnancies result from inconsistent, incorrect, or nonuse of a contraceptive method. Diminished sexual function and pleasure may be a barrier to using hormonal contraception. This study explores sexual function and behaviors of women in relation to the use of hormonal vs. nonhormonal methods of contraception. Data were collected as part of an online health and sexuality study of women. Main outcomes variables assess frequencies in two domains: (i) sexual function (proportion of sexual events with experiences of pain or discomfort, arousal, contentment and satisfaction, pleasure and enjoyment, lubrication difficulty, and orgasm) and (ii) sexual behavior (number of times engaged in sexual activity, proportion of sexual events initiated by the woman, and proportion of sexual events for which a lubricant was used). Sociodemographic variables and contraceptive use were used as sample descriptors and correlates. The recall period was the past 4 weeks. The sample included 1,101 women with approximately half (n = 535) using a hormonal contraceptive method exclusively or a combination of a hormonal and nonhormonal method, and about half (n = 566) using a nonhormonal method of contraception exclusively. Hierarchical regression analyses were conducted to examine the relation of hormonal contraceptive use to each of the dependent variables. Women using a hormonal contraceptive method experienced less frequent sexual activity, arousal, pleasure, and orgasm and more difficulty with lubrication even when controlling for sociodemographic variables. This study adds to the literature on the potential negative sexual side effects experienced by many women using hormonal contraception. Prospective research with diverse women is needed to enhance the understanding of potential negative sexual side effects of hormonal contraceptives, their prevalence, and possible mechanisms. Clinical and counseling implications are discussed. © 2013 International Society for Sexual Medicine.

The efficacy of a lidocaine-infused pain pump for postoperative analgesia following elective augmentation mammaplasty or abdominoplasty.

Chavez-Abraham, Victor; Barr, Jason S; Zwiebel, Paul C

2011-08-01

Postoperative pain management following aesthetic plastic surgery traditionally has been achieved by systemic administration of several narcotic pain medications. Because this method can lead to undesirable side effects such as sedation, nausea, vomiting, and respiratory depression, a more efficacious method of postoperative analgesia with fewer side effects needs to be implemented in outpatient cosmetic surgery. From March of 2003 until December of 2008, 690 patients underwent augmentation mammaplasty and 215 patients underwent abdominoplasty. All of these patients were equipped with an elastomeric continuous infusion pump postoperatively and were prescribed oral narcotics. Prior to 2003, patients were prescribed only oral narcotics postoperatively. A retrospective chart review of patients before and after implementation of the pain pump was undertaken to review the perceived pain patients experienced postoperatively with and without the pump. The self-administration of oral narcotics was also assessed. Patients equipped with the pain pump experienced a statistically significant decrease in perceived pain compared to those without the pump (augmentation mammaplasty: 2.27 vs. 3.68, p < 0.05; abdominoplasty: 2.81 vs. 4.32, p < 0.05). Similarly, patients with the pump saw a statistically significant decrease in the use of the oral narcotic Vicodin™ at 72 h postoperatively (5 mg hydrocodone/500 mg acetaminophen, Abbott Laboratories, Abbott Park, IL) (augmentation mammaplasty: 26.5 mg/2650 mg vs. 49 mg/4900 mg, p < 0.01; abdominoplasty: 29.5 mg/2950 mg vs. 56.5 mg/5650 mg, p < 0.01). The utilization of a continuous-infusion pain pump following augmentation mammaplasty or abdominoplasty is an efficacious method to significantly reduce both the amount of pain patients experience and the quantity of narcotics used postoperatively.

Tackling in Rugby Union is an open skill which can involve high-speed collisions and is the match event associated with the greatest proportion of injuries. This study aimed to analyse the biomechanics of rugby tackling under three conditions: from a stationary position, with dominant and non-dominant shoulder, and moving forward, with dominant shoulder. A specially devised contact simulator, a 50-kg punch bag instrumented with pressure sensors, was translated towards the tackler (n = 15) to evaluate the effect of laterality and tackling approach on the external loads absorbed by the tackler, on head and trunk motion, and on trunk muscle activities. Peak impact force was substantially higher in the stationary dominant (2.84 ± 0.74 kN) than in the stationary non-dominant condition (2.44 ± 0.64 kN), but lower than in the moving condition (3.40 ± 0.86 kN). Muscle activation started on average 300 ms before impact, with higher activation for impact-side trapezius and non-impact-side erector spinae and gluteus maximus muscles. Players' technique for non-dominant-side tackles was less compliant with current coaching recommendations in terms of cervical motion (more neck flexion and lateral bending in the stationary non-dominant condition) and players could benefit from specific coaching focus on non-dominant-side tackles.

Music evokes vicarious emotions in listeners

Why do we listen to sad music? We seek to answer this question using a psychological approach. It is possible to distinguish perceived emotions from those that are experienced. Therefore, we hypothesized that, although sad music is perceived as sad, listeners actually feel (experience) pleasant emotions concurrent with sadness. This hypothesis was supported, which led us to question whether sadness in the context of art is truly an unpleasant emotion. While experiencing sadness may be unpleasant, it may also be somewhat pleasant when experienced in the context of art, for example, when listening to sad music. We consider musically evoked emotion vicarious, as we are not threatened when we experience it, in the way that we can be during the course of experiencing emotion in daily life. When we listen to sad music, we experience vicarious sadness. In this review, we propose two sides to sadness by suggesting vicarious emotion. PMID:24910621

We report the case of a 64-year-old woman with cystic meningioma; this patients was otherwise healthy and experienced formed visual hallucinations after excision of the tumor. She experienced diplopia associated with metamorphopsia, which had persisted for 5 years only when she laid down and turned on her left side. After the excision of the convexity meningioma located in the right temporoparietal lobe, she experienced several types of formed visual hallucinations such as closet-like pictures, flowers sketched on stones, falling maple-like leaves, and moving or wriggling dwarves. She was alert and her visual field was normal; further, she did not experience delirium or seizures. She experienced these hallucinations only when she closed her eyes; these hallucinations persisted for 3 days after the operation. The patient illustrated her observations with beautiful sketches, and the mechanism of visual hallucinations was studied.

Frontal Plane Knee Moments in Golf: Effect of Target Side Foot Position at Address

PubMed Central

Lynn, Scott K.; Noffal, Guillermo J.

2010-01-01

Golf has the potential to keep people active well into their later years. Injuries to the target side knee have been reported in golfers, yet no mechanisms for these injuries have been proposed. The loads on the knee during the golf swing may be insufficient to cause acute injury, yet they may be a factor in the progression of overuse/degenerative conditions; therefore, research developing swing modifications that may alter loading of the knee is warranted. It has been suggested that the proper golf set-up position has the target-side foot externally rotated but no reasoning for this modification has been provided. Frontal plane knee moments have been implicated in many knee pathologies. Therefore, this study used a 3-dimensional link segment model to quantify the frontal plane knee moments during the golf swing in a straight (STR) and externally rotated (EXT) target-side foot position. Subjects were 7 collegiate golfers and knee moments were compared between conditions using repeated measures T-tests. The golf swing knee moment magnitudes were also descriptively compared to those reported for two athletic maneuvers (drop jump landing, side-step cutting) and activities of daily living (gait, stair ascent). The EXT condition decreased the peak knee adduction moment as compared to the STR condition; however, foot position had no effect on the peak knee abduction moment. Also, the magnitude of the knee adduction moments during the two activities of daily living were 9-33% smaller than those experienced during the two different golfing conditions. The drop jump landing and golf swing knee moments were of similar magnitude (STR= - 5%, EXT= + 8%); however, the moments associated with side- step cutting were 50-71% larger than those on the target side knee during the golf swing. The loading of the target side knee during the golf swing may be a factor in the development and progression of knee pathologies and further research should examine ways of attenuating these loads through exercise and swing modifications. Key points An externally rotated front foot position at address would be recommended for those with medial knee pathology in the target side limb. There is a large valgus moment on the target side knee during the golf swing that is not decreased with external rotation of the foot at address. The potential of the knee moments on the target side limb to lead to knee pathologies in golfers needs to be further investigated. PMID:24149696

Pharmacokinetic and pharmacodynamic profile of supratherapeutic oral doses of Δ9-THC in cannabis users

2013-01-01

Oral Δ9-tetrahydrocannabinol (Δ9-THC) has been evaluated as a medication for cannabis dependence, but repeated administration of acute oral doses up to 40 mg has not been effective at reducing drug-taking behavior. Larger doses might be necessary to affect cannabis use. The purpose of the present study was therefore to determine the physiological and behavioral effects of oral Δ9-THC at acute doses higher than those tested previously. The pharmacokinetic and pharmacodynamic profile of oral Δ9-THC, administered in ascending order in 15 mg increments across separate sessions, up to a maximum of 90 mg, was determined in seven cannabis users. Five subjects received all doses and two experienced untoward side effects at lower doses. Δ9-THC produced a constellation of effects consistent with previous clinical studies. Low cannabinoid concentrations were associated with significant effects on drug- sensitive measures, although progressively greater levels did not lead to proportionately larger drug effects. Considerable variability in Cmax and tmax was observed. Doses of oral Δ9-THC larger than those tested previously can be administered to individuals with a history of cannabis use, although given the pharmacokinetic variability of oral Δ9-THC and individual differences in sensitivity, individualized dose adjustment is needed to avoid side effects and maximize therapeutic response.

Closed temporal bone fractures due to cranial trauma often result in facial nerve injury, frequently inducing incomplete facial paralysis. Conventional hypoglossal-facial nerve end-to-end neurorrhaphy may not be suitable for these injuries because sacrifice of the lesioned facial nerve for neurorrhaphy destroys the remnant axons and/or potential spontaneous innervation. we modified the classical method by hypoglossal-facial nerve "side"-to-side neurorrhaphy using an interpositional predegenerated nerve graft to treat these injuries. Five patients who experienced facial paralysis resulting from closed temporal bone fractures due to cranial trauma were treated with the "side"-to-side neurorrhaphy. An additional 4 patients did not receive the neurorrhaphy and served as controls. Before treatment, all patients had suffered House-Brackmann (H-B) grade V or VI facial paralysis for a mean of 5 months. During the 12-30 months of follow-up period, no further detectable deficits were observed, but an improvement in facial nerve function was evidenced over time in the 5 neurorrhaphy-treated patients. At the end of follow-up, the improved facial function reached H-B grade II in 3, grade III in 1 and grade IV in 1 of the 5 patients, consistent with the electrophysiological examinations. In the control group, two patients showed slightly spontaneous innervation with facial function improved from H-B grade VI to V, and the other patients remained unchanged at H-B grade V or VI. We concluded that the hypoglossal-facial nerve "side"-to-side neurorrhaphy can preserve the injured facial nerve and is suitable for treating significant incomplete facial paralysis resulting from closed temporal bone fractures, providing an evident beneficial effect. Moreover, this treatment may be performed earlier after the onset of facial paralysis in order to reduce the unfavorable changes to the injured facial nerve and atrophy of its target muscles due to long-term denervation and allow axonal regrowth in a rich supportive environment.

Should ribavirin be used to treat hepatitis C in dialysis patients?

Carrion, Andres F; Fabrizi, Fabrizio; Martin, Paul

Hepatitis C virus infection adversely affects outcomes in patients with chronic kidney disease undergoing maintenance dialysis. Pegylated interferon and ribavirin, the standard-of-care treatment in patients with intact renal function, is associated with severe side effects, toxicity, and high dropout rates in this population. Ribavirin has an important role in maintaining antiviral response following completion of therapy and increases sustained viral response (SVR) rates. However, the use of ribavirin in dialysis patients has been limited by the high frequency of severe hemolytic anemia and is currently reserved for study protocols and highly selected candidates treated at experienced centers. Encouraging data from small trials have shown a significant increase in SVR rates with the use of different dosing regimens of ribavirin in addition to interferon-based therapy and aggressive erythroid-stimulating agent support in dialysis patients. Use of ribavirin in selected dialysis patients, particularly renal transplant candidates, by experienced clinicians is appropriate. © 2011 Wiley Periodicals, Inc.

Many adolescents and young adults purchase and use over-the-counter (OTC) medications, and some may take these medications without reading about how to use them. Most do read package inserts and labels to learn about the medication, but studies examining what influences label reading for youth are needed. This study assessed factors related to label reading for young people, including demographic variables (gender, health status) and the types of information they were seeking about the medication. Eight hundred and seventy-six high school and college students participated, and most reported reading labels or package inserts to learn about medications. Participants experiencing pain were more likely to read labels, except for those experiencing headaches who reported being less likely to read labels. When reading labels, participants were interested in information about side effects, ingredients, dosage instructions, and symptoms treated by the medication. Future research should examine whether youth take medications as directed and what factors make labels and inserts easier to read and understand.

Dynamic perception of dynamic affordances: walking on a ship at sea.

Motion of the surface of the sea (waves, and swell) causes oscillatory motion of ships at sea. Generally, ships are longer than they are wide. One consequence of this structural difference is that oscillatory ship motion typically will be greater in roll (i.e., the ship rolling from side to side) than in pitch (i.e., the bow and stern rising and falling). For persons on ships at sea, affordances for walking on the open deck should be differentially influenced by ship motion in roll and pitch. Specifically, the minimum width of a walkable path should be greater when walking along the ship's short, or athwart axis than when walking along its long, or fore-aft axis. On a ship at sea, we evaluated the effects of walking in different directions (fore-aft vs. athwart) on actual walking performance. We did this by laying out narrow paths on the deck and asking participants (experienced maritime crewmembers) to walk as far as they could while remaining within the lateral path boundaries. As predicted, participants walked farther along the athwart path than along the fore-aft path. Before actual walking, we evaluated participants' judgments of their walking ability in the fore-aft and athwart directions. These judgments mirrored the observed differences in walking performance, and the accuracy of judgments did not differ between the two directions. We conclude that experienced maritime crewmembers were sensitive to affordances for walking in which the relevant properties of the environment were exclusively dynamic.

Whipple surgery (pancreaticodeudenectomy) has a high complication rate. We aimed to evaluate whether adding Braun jejunojejunostomy (side-to-side anastomosis of afferent and efferent loops distal to the gastrojejunostomy site) to a standard Whipple procedure would reduce postoperative complications. We conducted a randomized clinical trial comparing patients who underwent standard Whipple surgery (standard group) and patients who underwent standard Whipple surgery with Braun jejunojejunostomy (Braun group). Patients were followed for 1 month after the procedure and postoperative complications were recorded. Our study included 30 patients: 15 in the Braun and 15 in the standard group. In the Braun group, 4 (26.7%) patients experienced 6 complications, whereas in the standard group, 7 (46.7%) patients experienced 11 complications (p = 0.14). Complications in the Braun group were gastrointestinal bleeding and wound infection (n = 1 each) and delayed gastric emptying and pulmonary infection (n = 2 each). Complications in the standard group were death, pancreatic anastomosis leak and biliary anastomosis leak (n = 1 each); gastrointestinal bleeding (n = 2); and afferent loop syndrome and delayed gastric emptying (n = 3 each). There was no significant difference between groups in the subtypes of complications. Our results showed that adding Braun jejunojejunostomy to standard Whipple procedure was associated with lower rates of afferent loop syndrome and delayed gastric emptying. However, more studies are needed to define the role of Braun jejunojejunostomy in this regard. IRCT2014020316473N1 (www.irct.ir).

Vibration anesthesia is an effective pain-reduction technique for facial cosmetic injections. The analgesic effect of this method was tested in this study during facial dermal filler injections. The study aimed to evaluate the safety and efficacy of vibration anesthesia for these facial injections. This prospective study analyzed 41 patients who received dermal filler injections to the nasolabial folds, tear troughs, cheeks, and other facial sites. The injections were administered in a randomly assigned split-face design. One side of the patient's face received vibration together with dermal filler injections, whereas the other side received dermal filler injections alone. The patients completed a posttreatment questionnaire pertaining to injection pain, adverse effects, and preference for vibration with future dermal filler injections. The patients experienced both clinically and statistically significant pain reduction when a vibration stimulus was co-administered with the dermal filler injections. No adverse events were reported. The majority of the patients (95 %) reported a preference for vibration anesthesia with subsequent dermal filler injections. Vibration is a safe and effective method of achieving anesthesia during facial dermal filler injections. This journal requires that authors assign a level of evidence to each article.

Hemifacial spasm (HFS) is a peripherally-induced movement disorder characterized by the involuntary, unilateral, intermittent, irregular, tonic or clonic contractions of muscles innervated by the ipsilateral facial nerve. Kindling-like hyperactivity of the facial nucleus induced by constant stimulation of compressing artery is considered as the predominant mechanism underlying the pathogenesis of HFS. As a treatment for HFS, microsurgical decompression and botulinum toxin injection have been shown to be highly successful. Anticonvulsant drugs relieve HFS in some patients; however, the use of such drugs is limited owing to their side effects, predominantly in elderly patients. We experienced two elderly HFS patients who exhibited a marked response to levetiracetam (LEV) without side effects. Although the exact underlying pharmacological mechanism remains unknown, we assume anti-kindling effect as one of the important pharmacological mechanism underlying the effect of LEV against HFS. Moreover, LEV is considered to be suitable for use in elderly patients because of its good tolerability. In addition, the lack of hepatic induction or inhibition makes it an easy and safe drug when used in addition to other anticonvulsants. Although the long-term benefit remains unknown, LEV may represent an alternative treatment for elderly HFS patients who are unable to undergo or decline surgical intervention and/or botulinum toxin injections or are intolerant to other anticonvulsants.

"To understand and protect our home planet, to explore the universe and search for life, and to inspire the next generation of explorers" is NASA's mission. The Systems Management Office at Johnson Space Center (JSC) is searching for methods to effectively manage the Center's resources to meet NASA's mission. D-Side is a group multi-criteria decision support system (GMDSS) developed to support facility decisions at JSC. D-Side uses a series of sequential and structured processes to plot facilities in a three-dimensional (3-D) graph on the basis of each facility alignment with NASA's mission and goals, the extent to which other facilities are dependent on the facility, and the dollar value of capital investments that have been postponed at the facility relative to the facility replacement value. A similarity factor rank orders facilities based on their Euclidean distance from Ideal and Nadir points. These similarity factors are then used to allocate capital improvement resources across facilities. We also present a parallel model that can be used to support decisions concerning allocation of human resources investments across workforce units. Finally, we present results from a pilot study where 12 experienced facility managers from NASA used D-Side and the organization's current approach to rank order and allocate funds for capital improvement across 20 facilities. Users evaluated D-Side favorably in terms of ease of use, the quality of the decision-making process, decision quality, and overall value-added. Their evaluations of D-Side were significantly more favorable than their evaluations of the current approach.

2012-06-01

A guarded-hot-plate apparatus [1] has been developed to measure the thermal conductivity of spray-on foam insulations (SOFI) at temperatures ranging from 30 K to 300 K. The foam tested in the present study is NCFI 24-124, a polyisocyanurate foam used on the External Tanks of the Space Shuttle. The foam was tested first in ambient pressure air, then evacuated and tested once more. These thermal conductivities were compared to the thermal conductivity taken from a sample immediately after being subjected to conditions similar to those experienced by the foam while on the launch pad at Kennedy Space Center. To mimic the conditions experienced on the launch pad, an apparatus was built to enclose one side of the foam sample in a warm, humid environment while the other side of the sample contacts a stainless steel surface held at 77 K. The thermal conductivity data obtained is also compared to data found in the literature.

An exact solution for a thick domain wall in general relativity

An exact solution of the Einstein equations for a static, planar domain wall with finite thickness is presented. At infinity, density and pressure vanish and the space-time tends to the Minkowski vacuum on one side of the wall and to the Taub vacuum on the other side. A surprising feature of this solution is that the density and pressure distribution are symmetric about the central plane of the wall whereas the space-time metric and therefore also the gravitational field experienced by a test particle is asymmetric.

Intra-atrial communication was mandatory for several congenital cardiac diseases, such as pulmonary atresia with intact ventricular septum (PA/IVS), and either sided aortoventricular valve atresia. We assessed whether the new methods of atrial septal defect(ASD)creation was effective. We experienced 4 cases of the surgical atrial septostomy performed under on-pump beating. We used a new device, a circular punch out defect creator. All cases were alive. The mean ASD diameter was enlarged from 4.37 mm to 5.55 mm and the mean ASD shunt flow was significantly decreased from 1.47 m/s to 1.11 m/s. We performed the surgical atrial septostomy using an aortic puncher under beating heart effectively and safely.

Pediatric Bipolar Disorder: Combination Pharmacotherapy, Adverse Effects, and Treatment of High-Risk Youth.

PubMed

Chang, Kiki D

2016-01-01

Treating bipolar disorder in pediatric patients is challenging because data from rigorous trials of pharmacotherapy in this population are still not plentiful enough. Furthermore, the treatment of children and adolescents is complicated by the frequent need to combine pharmacotherapies to address all bipolar symptoms as well as this population's elevated risk for experiencing side effects. Additionally, young patients with depressive episodes who are at high risk for developing bipolar disorder need careful treatment to prevent or delay the emergence of mania. Despite these challenges, clinicians should evaluate the existing pediatric literature, extrapolate evidence obtained from adult patients, and draw from clinical experience to guide treatment decisions for children and adolescents with bipolar disorder. © Copyright 2016 Physicians Postgraduate Press, Inc.

We present the design and performance of the LIGO Input Optics subsystem as implemented for the sixth science run of the LIGO interferometers. The Initial LIGO Input Optics experienced thermal side effects when operating with 7 W input power. We designed, built, and implemented improved versions of the Input Optics for Enhanced LIGO, an incremental upgrade to the Initial LIGO interferometers, designed to run with 30 W input power. At four times the power of Initial LIGO, the Enhanced LIGO Input Optics demonstrated improved performance including better optical isolation, less thermal drift, minimal thermal lensing, and higher optical efficiency. The success of the Input Optics design fosters confidence for its ability to perform well in Advanced LIGO.

Research on the safety and efficacy of continuous lidocaine infusions (CLIs) for the treatment of pain in the pediatric setting is limited. This article describes a series of pediatric oncology patients who received lidocaine infusions for refractory, longstanding, cancer-related pain. This is a retrospective review of patients who underwent lidocaine infusions to manage severe, opioid-refractory, cancer-related pain. Four patients ranging in age from 8 to 18 years were admitted to a pediatric hospital for their medical conditions and/or pain management. Structured chart review established demographic and diagnosis information, infusion rates, side effects, and efficacy of infusions in providing pain relief. Lidocaine bolus doses, infusion rates, serum concentrations, and subjective pain scores were analyzed. Median pain scores prior to lidocaine infusions were 8/10, falling to 2/10 at the infusion termination (P < 0.003), and rising to 3/10 in the first 24 hr after lidocaine (P < 0.029 compared to preinfusion pain). The infusions were generally well tolerated, with few side effects noted. In most cases, the improvement in pain scores persisted beyond termination of the infusion. CLIs were a helpful adjuvant in the four cases presented and may be an effective therapy for a more diverse array of refractory cancer pain. The majority of patients experienced pain relief well beyond the metabolic elimination of the lidocaine, corroborating a modulation effect on pain windup. Additional research regarding infusion rates, serum concentrations, side effects, and outpatient follow-up in a larger group of patients will provide additional insight into the role and safety of this therapy in children. © 2016 Wiley Periodicals, Inc.

The neodymium-doped yttrium aluminum garnet (NdYAG) laser therapy has been a popular technique for facial rejuvenation but certain adverse effects like post-inflammatory hyperpigmentation are issues of concern to Asian patients. To assess the outcome following combined treatment with vitamin C sonophoresis and NdYAG laser, in selected cases of facial hyperpigmentation. Twenty three women with dyschromia or melasma who had undergone five sessions of Q-switched NdYAG laser therapy followed by transdermal delivery of vitamin C via sonophoresis were selected after a retrospective review of case records. The objective and subjective clinical outcomes and the side effects, including erythema, scaling, pruritus, dryness and post-inflammatory hyperpigmentation were evaluated. In both objective or subjective outcomes, 91.3% (21/23) of the patients showed an excellent or better outcome, while 8.7% (2/23) showed no change. A majority of the patients (73.9%, 17/23) experienced no post-inflammatory hyperpigmentation or had slight post-inflammatory hyperpigmentation which quickly resolved within 1 week. Only one (4.3%) patient had extreme post-inflammatory hyperpigmentation which lasted for over a month. This was a retrospective study without a control group; a comparative study with a control group (patients treated with the laser alone, without vitamin C sonopheresis) is needed to determine the difference in the outcome. The use of vitamin C sonophoresis along with NdYAG laser may reduce the incidence of adverse effects in Asian patients. Patients experienced obvious improvement in hyperpigmentation and had lower chances of experiencing extreme or severe post-inflammatory hyperpigmentation.

This study compares the efficacy, side effects and patient convenience of vaginal and rectal routes of administration of progesterone suppositories (Cyclogest) when used for luteal phase support during in vitro fertilization cycles, through the use of antagonist protocols. 147 patients who underwent intra-cytoplasmic sperm injection cycle were randomized on the day of the embryo transfer (ET) by a computer-generated randomization program to receive 400 mg of Cyclogest either vaginally or rectally twice daily for up to 8 weeks. A pregnancy test was conducted 2 weeks after embryo transfer. If the pregnancy test was negative, the application was discontinued. On day 14th after embryo transfer, patient's acceptability and side effects were assessed using a questionnaire which was given to the patients on the day of ET prior to performing the pregnancy test. The clinical pregnancy rate at the 8th week of gestation and the level of luteal progesterone were evaluated. There were no substantial differences in the demographics or other characteristics between the two groups. There were no significant differences in serum P concentration 6 days after ET, the clinical pregnancy and abortion rates. The difficulty of administration route, the discomforts experienced following administration, and the proportion leaking out on the 14th day were similar between the two groups. Significantly more patients administering the medication per vagina had perineal irritation (21.3 vs. 2.2 %). The prevalence of tenesmus (35.1 vs. 21.1 %) and rectal itching (26.7 vs. 2.8 %) were significantly more in rectal route. This study demonstrates that the efficacy of Cyclogest is similar when administered via both the vaginal and rectal routes. Although their side effects differ, the ease of administration for patients and their preference are similar.

Automated side-chain model building and sequence assignment by template matching.

PubMed

Terwilliger, Thomas C

2003-01-01

An algorithm is described for automated building of side chains in an electron-density map once a main-chain model is built and for alignment of the protein sequence to the map. The procedure is based on a comparison of electron density at the expected side-chain positions with electron-density templates. The templates are constructed from average amino-acid side-chain densities in 574 refined protein structures. For each contiguous segment of main chain, a matrix with entries corresponding to an estimate of the probability that each of the 20 amino acids is located at each position of the main-chain model is obtained. The probability that this segment corresponds to each possible alignment with the sequence of the protein is estimated using a Bayesian approach and high-confidence matches are kept. Once side-chain identities are determined, the most probable rotamer for each side chain is built into the model. The automated procedure has been implemented in the RESOLVE software. Combined with automated main-chain model building, the procedure produces a preliminary model suitable for refinement and extension by an experienced crystallographer.

Although myocardial infarction (MI) is linked with both physical and psychological impairments, the possibility of patients also experiencing positive outcomes of MI has received far less attention in research and in clinical practice. In particular, this aspect has been under-investigated in older persons and in women. The purpose of this study was to investigate possible positive effects of illness, describe the patient characteristics and explore the nature and frequency of these effects in older women after MI. A cross-sectional postal survey was conducted in 145 women aged 62-80 years, three months to five years after MI. Self-reported socio-demographic and clinical data, in addition to data from medical records, were collected. A single-item question--"All in all, was there anything positive about experiencing an MI?"--was used to assess positive effects of illness, in addition to an open-ended question on the nature of possible positive effects. A majority of the women (65%) reported positive effects from their MI experience. The women perceiving positive effects did not differ from those who did not on socio-demographic and clinical variables, except for being older (p=0.007) and less often readmitted (p=0.029). The groups did not differ significantly as to disease severity and time since MI. Four themes emerged from the open-ended questioning on the nature of perceived positive effects of the illness: Appreciating Life (55%), Getting Health Care (42%), Making Lifestyle Changes (36%), and Taking More Care of Self and Others (29%). The findings contribute to a more complete picture of psychosocial issues in women after MI by providing evidence that positive effects are often experienced despite physical limitations. Nurses may use this knowledge as a tool in patient education and communication, although further research is needed to determine the most optimal interventions for MI patients.

Investigation of the Relationship of Vortex-Generated Sound and Airframe Noise

NASA Technical Reports Server (NTRS)

Smith, Sonya T.

1998-01-01

Airframe noise contributes the most to the environmental contamination from airports during take-off and landing. Two sources of noise are from the vortex-system associated with the slat and flap of multi-element wing designs. The flap-side edge vortex experiences bursting, known as vortex breakdown, at a critical deflection angle and experimental results show that this event may be one source of increased noise levels. Understanding of the edge roll-up phenomenon has increased but further focused studies on the role of the growth and bursting of the vortex structure are needed. The goal of the research is to plan a research program that will contribute to the understanding of the fluid physics of vortex breakdown and its relationship to noise production. The success of this program will lead to a priori predictions of when vortex breakdown will occur on the flap side-edge and accurate calculations of its effect on the noise level experienced by an observer near the aircraft during take-off and landing.

Preventing urinary tract infection: progress toward an effective Escherichia coli vaccine

PubMed Central

Brumbaugh, Ariel R; Mobley, Harry LT

2012-01-01

Uncomplicated urinary tract infections (UTIs) are common, with nearly half of all women experiencing at least one UTI in their lifetime. This high frequency of infection results in huge annual economic costs, decreased workforce productivity and high patient morbidity. At least 80% of these infections are caused by uropathogenic Escherichia coli (UPEC). UPEC can reside side by side with commensal strains in the gastrointestinal tract and gain access to the bladder via colonization of the urethra. Antibiotics represent the current standard treatment for UTI; however, even after treatment, patients frequently suffer from recurrent infection with the same or different strains. In addition, successful long-term treatment has been complicated by a rise in both the number of antibiotic-resistant strains and the prevalence of antibiotic-resistance mechanisms. As a result, preventative approaches to UTI, such as vaccination, have been sought. This review summarizes recent advances in UPEC vaccine development and outlines future directions for the field.

Mithuri users surveyed in Sri Lanka.

PubMed

1983-01-01

The Family Planning Association (FPA) of Sri Lanka completed a survey of Mithuri (oral contraceptive) users to determine consumer characteristics. The survey addressed issues such as purchasing habits, user patterns, dealer consumer relationships, levels of consumer satisfaction and motivation, prevalence of side effects, degree and level of medical consultations, and attitudes toward mass media product advertising. A mail survey was used to conduct this quantitative research to reduce the cost of collecting the data. Mail surveys offer the advantage of being able to reach a large number of respondents at a very reasonable cost, but they also require an accurate list of respondents who are representative of the population to be examined. Of the 681 questionnaires delivered, 442 were completed and returned. The majority of those surveyed (86%) purchased Mithuri at pharmacies that are within 5 miles of their residence. 73.2% of the women asked their husbands to make the purchase, and 67.6% purchased 2 cycles at a time. Most respondents reported experiencing no side effects from Mithuri. The majority of the few who experienced side effects considered them to be very slight. 2.7% of the respondents reported becoming pregnant while using Mithuri, 11 of whom ascribed the pregnancy to their failure to take the pill regularly. Most respondents said that they never missed a day. Husbands or "Western" medical practitioners were most often cited as the motivators to use Mithuri. Of the 82% of the respondents who had read the Mithuri newspaper advertisements, 87% indicated they approved of mass media advertising about contraceptives, primarily because they felt that making such information available was an urgent matter. Although advertisements and package circulars urged 1st time users to consult a physician before using Mithuri, less than half the respondents reported consulting any medical person, nurses, and midwives included. They also reported that the dealer gave no spontaneous advice on the use of Mithuri or any other contraceptive method nor had they as users sought any advice. The declared length of use indicates a satisfactory continuation rate and is supported by the fact that 94% of those included in the 1981 survey were still using Mithuri in June 1982. 84.5% of the respondents reported they were "completely satisfied" with Mithuri; 7.8% reported they were not satisfied at all but used Mithuri for convenience.

We designed an animal experiment to discover whether the phrenic nerve being transferred to the posterior division of the lower trunk with end-to-side neurotization was feasible and provided the theoretical basis. A sum of 36 Sprague-Dawley rats was randomly assigned to one of two groups. In Group A, the phrenic nerve was transferred to the posterior division of the lower trunk with end-to-side neurotization. In Group B, the posterior division of the lower trunk was directly sutured. The results of behavioral assessment, electrophysiology, histology and nerve fiber count and muscle weight at 12 weeks postoperatively were recorded. In Group A, none of the rats experienced tachypnea. The motion of slight toe extension was observed. The results of electrophysiology, histology and nerve fiber count and muscle weight in Group A were not as well as those of Group B, but gradually improved with time. The phrenic nerve being transferred to the posterior division of lower trunk with end-to-side neurotization can partially restore the function of toe extension in a rat model. Whether the function of digit extension can be restored by the phrenic nerve with end-to-side neurotization in humans still needs more practice in clinic.

A case of systemic ropivacaine toxicity from a continuous thoracic paravertebral block in an adult patient who received a lobectomy is presented. The catheter was placed by the surgeon. Eleven hours after the start of the infusion, the patient experienced an arrhythmia leading to death. The total venous plasma concentration of ropivacaine was high (3.2 μg/mL). Furthermore, the patient had severe hypoalbuminemia (albumin 24 g/L), which resulted in the increase of the unbound ropivacaine plasma concentration that was responsible for the toxic side effects.

Designing biologic selectivity for inflammatory bowel disease – role of vedolizumab

PubMed Central

Krupka, Niklas; Baumgart, Daniel C

2015-01-01

Crohn’s disease and ulcerative colitis are two chronic inflammatory bowel conditions. Current approved biologic therapies are limited to blocking tumor necrosis factor alpha. Unfortunately, some patients are primary nonresponders, experiencing a loss of response, intolerance, or side effects. This defines an unmet need for novel therapeutic strategies. The rapid recruitment and inappropriate retention of leukocytes is a hallmark of chronic inflammation and a potentially promising therapeutic target. Here we discuss the clinical trial results of vedolizumab (anti-α4β7, LDP-02, MLN-02, and MLN0002) and its impact on future management of inflammatory bowel disease. PMID:25552903

The curvilinear effect of work engagement on employees' turnover intentions.

PubMed

Caesens, Gaëtane; Stinglhamber, Florence; Marmier, Virginie

2016-04-01

Numerous studies have shown the positive consequences of work engagement for both organisations and employees experiencing it. For instance, research has demonstrated that work-engaged employees have lower levels of turnover intentions than non-engaged employees. However, in this research, we examined whether there is a dark side of work engagement. More precisely, we investigated whether the relationship between work engagement and employees' turnover intentions might be non-linear. Based on two different samples, our results indicated that the relationship between work engagement and employees' turnover intentions is curvilinear. The theoretical and practical implications of these results are discussed. © 2014 International Union of Psychological Science.

Beyond barriers: fundamental 'disconnects' underlying the treatment of breast cancer patients' sexual health.

2014-01-01

Sexual health concerns represent one of the most frequently experienced and longest-lasting effects of breast cancer treatment, but research suggests that service providers rarely discuss sexual health with their patients. Existing research examining barriers to addressing patients' sexual health concerns has focused on discrete characteristics of the provider-patient interaction without considering the broader context in which these interactions occur. Drawing on the experiences of 21 breast cancer survivors, this paper explores three ways in which fundamental cultural and structural characteristics of the cancer care system in the USA may prevent breast cancer survivors from addressing their sexual health concerns, including: (1) when patients discussed sexual health with their providers, their providers approached sexuality as primarily physical, while participants experienced complex, multidimensional sexual health concerns; (2) specialisation within cancer care services made it difficult for patients to identify the appropriate provider to address their concerns; and (3) the structure of cancer care literally disconnects patients from the healthcare system at the time when sexual side effects commonly emerged. These data suggest that addressing breast cancer survivors' sexual health concerns requires a multifaceted approach to health systems change.

The Effect of Recovery Duration on Vastus Lateralis Oxygenation, Heart Rate, Perceived Exertion and Time Motion Descriptors during Small Sided Football Games.

Small sided games (SSG) of football are an effective and efficient format to simultaneously train the physiological, technical, and tactical components of football. The duration of the recovery period between bouts of SSG will affect the physiological response to subsequent bouts. It was hypothesised that decreasing the duration of recovery periods separating serial SSG bouts would increase physiological, and perceptual responses, and decrease high speed running, and distance during SSG bouts. Twelve experienced footballers (mean ± SD; age 21 ± 3 yrs; VO2peak 64 ± 7 ml·min·kg-1; playing experience 15 ± 3 yrs) completed two SSG sessions. Each SSG consisted of 3 vs. 3 players and 6 bouts of 2 min duration, with bouts separated by either 30 s recovery (REC-30) or 120 s recovery (REC-120). Deoxygenated haemoglobin (HHb) in the vastus lateralis (VL) (using near infrared spectroscopy), heart rate (HR) and time motion descriptors (TMD) (speed and distance) were measured continuously during the SSG sessions and perceived exertion (RPE) was measured for each bout. During the recovery periods, in REC-30 compared to REC-120, there was a significant (p < 0.05) main effect of a higher HHb and HR. During the bouts, in REC-30 compared to REC-120, there were no significant differences in HHb, HR, RPE, or TMD, but within both REC-30 and REC-120 there were significant increases as a function of bout number in RPE. Although a four-fold increase in recovery period allowed a significant increase in the recovery of HHb and HR, this did not increase the physiological, and perceptual responses, or time motion descriptors during the bouts. These results could have been due to the regulation of effort (pacing), in these experienced players performing an exercise task to which they were well adapted.

Trends in Tramadol: Pharmacology, Metabolism, and Misuse.

PubMed

Miotto, Karen; Cho, Arthur K; Khalil, Mohamed A; Blanco, Kirsten; Sasaki, Jun D; Rawson, Richard

2017-01-01

Tramadol is a unique analgesic medication, available in variety of formulations, with both monoaminergic reuptake inhibitory and opioid receptor agonist activity increasingly prescribed worldwide as an alternative for high-affinity opioid medication in the treatment of acute and chronic pain. It is a prodrug that is metabolized by cytochrome P450 (CYP) enzymes CYP2D6 and CYP3A4 to its more potent opioid analgesic metabolites, particularly the O-demethylation product M1. The opioid analgesic potency of a given dose of tramadol is influenced by an individual's CYP genetics, with poor metabolizers experiencing little conversion to the active M1 opioid metabolite and individuals with a high metabolic profile, or ultra-metabolizers, experiencing the greatest opioid analgesic effects. The importance of the CYP metabolism has led to the adoption of computer clinical decision support with pharmacogenomics tools guiding tramadol treatment in major medical centers. Tramadol's simultaneous opioid agonist action and serotonin (5-HT) and norepinephrine reuptake inhibitory effects result in a unique side effect profile and important drug interactions that must be considered. Abrupt cessation of tramadol increases the risk for both opioid and serotonin-norepinephrine reuptake inhibitor withdrawal syndromes. This review provides updated important information on the pharmacology, pharmacokinetics, CYP genetic polymorphisms, drug interactions, toxicity, withdrawal, and illicit use of tramadol.

The lower body muscle activation of intermediate to experienced kayakers when navigating white water.

In white-water kayaking, the legs play a vital part in turning, stabilising and bracing actions. To date, there has been no reported information on neuromuscular activation of the legs in an authentic white-water environment. The aim of the current study was to identify lower body muscle activation, using 'in-boat' electromyography (EMG), whilst navigating a white-water run. Ten experienced male kayakers (age 31.5 ± 12.5 yr, intermediate to advanced experience) completed three successful runs of an international standard white-water course (grade 3 rapids), targeting right and left sides of the course, in a zigzag formation. Surface EMG (sEMG) outputs were generated, bilaterally, for the rectus femoris (RF), vastus lateralis, biceps femoris and gastrocnemius, expressed as a percentage of a dynamic maximal voluntary contraction (dMVC). Only RF showed significantly higher activation than any muscle on the left side of the body, and only on the left side of the course (P = .004; ETA(2) = 0.56). Other results showed no significant difference between muscle activation in the right and left legs during each run, nor when assessed at either the right or left side of the course (P > .05). These findings indicate that contralateral symmetry in lower limb muscle activation is evident during white-water kayaking. This symmetry may provide a stable base to allow more asymmetrical upper body and trunk movements to be fully optimised. Lower body symmetry development should be considered useful in targeted training programmes for white-water kayakers.

2017-12-01

To assess auditory localization accuracy and speech reception threshold (SRT) in complex noise conditions in adult patients with acquired single-sided deafness, after intervention with a cochlear implant (CI) in the deaf ear. Nonrandomized, open, prospective patient series. Tertiary referral university hospital. Eleven patients with late-onset single-sided deafness (SSD) and normal hearing in the unaffected ear, who received a CI. All patients were experienced CI users. Unilateral cochlear implantation. Speech perception was tested in a complex multitalker equivalent noise field consisting of multiple sound sources. Speech reception thresholds in noise were determined in aided (with CI) and unaided conditions. Localization accuracy was assessed in complete darkness. Acoustic stimuli were radiated by multiple loudspeakers distributed in the frontal horizontal plane between -60 and +60 degrees. In the aided condition, results show slightly improved speech reception scores compared with the unaided condition in most of the patients. For 8 of the 11 subjects, SRT was improved between 0.37 and 1.70 dB. Three of the 11 subjects showed deteriorations between 1.22 and 3.24 dB SRT. Median localization error decreased significantly by 12.9 degrees compared with the unaided condition. CI in single-sided deafness is an effective treatment to improve the auditory localization accuracy. Speech reception in complex noise conditions is improved to a lesser extent in 73% of the participating CI SSD patients. However, the absence of true binaural interaction effects (summation, squelch) impedes further improvements. The development of speech processing strategies that respect binaural interaction seems to be mandatory to advance speech perception in demanding listening situations in SSD patients.

The purpose of the study was to (1) investigate the rate of return to play among Major League Baseball (MLB) athletes after anterior cruciate ligament reconstruction (ACLR), (2) determine the impact of ACL injury on ability to perform baseball-specific planting and pivoting tasks (batting and stealing bases), and (3) to explore the effect of the injured side on these metrics. ACL injury data from 1999 to 2012 were compiled, along with player performance statistics recorded for players with at least 30 games before ACL injury. Predictor variables included side of injury and outcome variables focused on batting average, stolen bases, and number of times caught stealing before injury and after surgery. Twenty-three of 26 (88%) players were able to return to at least 30 games after ACLR, although they experienced a decline of 21.2% in number of games played (P = .004). Those who had a ACLR for a rear batting leg injury averaged a 12.3% decline in batting average, whereas those who had ACLR for a lead leg injury had a 6.4% increase in batting average (P = .04). Side of injury was not predictive of stolen base metrics. The overall rate of return to play among MLB position players after ACLR was 88%, although there was a 21.2% decline in the number of games played postoperatively. Injury to the rear batting leg resulted in a lower returning batting average compared with an injury to the lead batting leg. Side of injury had no effect on stolen bases or on the number of times a player was caught stealing. Level IV, therapeutic case series. Copyright © 2015 Arthroscopy Association of North America.

Goodell, Teresa T.; Bargo, Paulo R.; Jacques, Steven L.

2002-06-01

Background: Subjective measures are considered the gold standard in palliative care evaluation, but no studies have evaluated palliative photodynamic therapy (PDT) subjectively. If PDT is to be accepted as a palliative therapy for later-stage obstructing esophageal and lung cancer, evidence of its effectiveness and acceptability to patients must be made known. Study Design/Materials and Methods: This ongoing study's major aim is to evaluate subjective outcomes of PDT in patients with obstructing esophageal and lung cancer. Existing measures of health status, dysphagia and performance status were supplemented with an instrument developed to evaluate PDT symptom relief and side effect burden, the PDT Side Effects Survey (PSES). Results: PDT patients treated with porfimer sodium (Photofrin) and 630-nm light experienced reduced dysphagia grade and stable performance status for at least one month after PDT (N= 10-17), but these effects did not necessarily persist at three months. Fatigue, appetite and quality of life may be the most burdensome issues for these patients. Conclusions: Preliminary data suggest that the PSES is an acceptable and valid tool for measuring subjective outcomes of palliative PDT. This study is the first attempt to systematically evaluate subjective outcomes of palliative PDT. Multi-center outcomes research is needed to draw generalizable conclusions that will establish PDT's effectiveness in actual clinical practice and enhance the wider adoption of PDT as a cancer symptom relief modality.

Intra-uterine contraceptive devices.

PubMed

Elias, J

1985-05-01

Among the advantages of IUDs are the device's high continuation rate, the lack of systemic side effects, and the absence of a need for continual motivation to practice contraception. The effectiveness of plastic IUDs is directly proportional to their surface area, but the degree of excessive bleeding experienced is inversely related to device size. Thus, devices represent a compromise between large size for effectiveness and small size for acceptability. The optimum time to fit an IUD is during the 1st hald of the menstrual cycle. Absolute contraindications to IUD use include the presence of active pelvic inflammatory disease, undiagnosed irregular bleeding, a history of ectopic pregnancy or tubal surgery, and a distorted uteine cavity. Failure rates associated with IUD use range from 2-3% in the 1st year and then decrease. Since the main mechanism of action appears to be production of a sterile inflammatory reaction in the uterine cavity, the IUD prevents intrauterine pregnancy more effectively than ectopic pregnancy. Nonetheless, there is little evidence to suggest that IUD use actually increases the incidence of ectopic pregnancy. Resumption of fertility after IUD removal is not delayed. There is not need to change inert plastic IUDs in women who remain symptom free. The copper devices should be changed every 3-4 years. A search is under way for antifertility agents that can be incorporated into the device to reduce side effects. In general, the IUD is most suitable for older, parous women.

Chronic pain is a serious problem for geriatric patients. Conventional pharmacotherapy with nonsteroidal anti-inflammatory drugs or opiates is often accompanied by serious side effects. An 87-year-old woman with severe joint pain due to osteoarthritis of the knee presented with side effects from fentanyl therapy. She was subsequently treated in an inpatient setting with leeches, phytotherapy, physiotherapy and three single doses of metamizol. Prospective single-case study. Pain reduction was assessed with a numeric rating scale (0-10; 0 = minimum; 10 = maximum), mobility by walking distance, and activities of daily living by Barthel index. The association between complementary therapy and the changes observed in the patient under treatment were evaluated using cognition-based medicine. Under complementary therapy, the patient experienced a clear reduction in pain (from 8 to 3 points on the numeric rating scale); regained the ability to walk (increase in walking distance from 0 to 70 m); and showed improvements in activities of daily living (increase in Barthel index from 45 to 65). An association between pain reduction and the complementary treatment setting seems likely. The role of complementary pain therapy in geriatric patients should be evaluated systematically. 2008 S.

Previous interventions in colleges to improve human papillomavirus (HPV) vaccination have not been highly successful. Although barriers have been assessed in traditional colleges, less is known about vaccination barriers in community colleges. We approached students aged 18-26 years old enrolled at a community college for an in-person semi-structured qualitative interview on HPV vaccination and health, with questions guided by the Theory of Planned Behavior. Data collection took place between April 2015 and December 2015. Thematic analysis techniques were used to analyze the data. During interviews with 19 students, 4 themes emerged, including: general vaccine attitudes, barriers to HPV vaccination, motivators to HPV vaccination, and social influences. Participants felt that vaccines were beneficial, but were concerned about side effects. They felt that getting the HPV vaccine would be inconvenient, and they did not know enough about it to decide. Most would not trust their friends' opinions, but would want to know about side effects that their vaccinated friends experienced. Successful interventions at community colleges should include several components to increase convenience as well as utilize interactive methods to promote HPV vaccine awareness. Copyright © 2018.

Osteogenesis imperfecta is a heritable disorder of bone connective tissue. Type III has a high incidence in the black pop-ulation of South Africa. Affected people experience numerous fractures, bone pain and progressive disability. Until the introduction of bisphosphonates to reduce fracture incidence, treatment revolved around orthopaedic and supportive care. Objective. To assess the subjective attitude of patients towards pamidronate treatment. Thirty black patients with osteogenesis imperfecta type III treated at Universitas Hospital were approached and 26 were included in this study. Patients or their parents were interviewed using a standardised researcher-administered questionnaire, either in person or by telephone. Most patients reported a reduction in symptoms, a feeling of increased wellbeing, increased strength and rated the pamidronate treatment highly. The intravenous route of administration and the side-effects experienced were bearable. Overall all patients would recommend this treatment to other affected persons. This is first study to look at bisphosphonate treatment for osteogenesis imperfecta type III in black South Africans. The treatment is well tolerated and highly rated by the patients. Reported improvements and side-effects are similar to those reported in other populations. Using this form of treatment in this population is supported by these findings.

Data from 37 dogs with nasal carcinomas treated with two or more coarsely fractionated courses of radiation therapy (RT) were retrospectively reviewed. The median radiation dose for the first course of RT was 24 Gray (Gy). All dogs clinically responded, and 11 had complete resolution of signs for a median of 114 days. Dogs were retreated at relapse, with a median dose of 20 Gy, and 26 of 37 dogs (70%) had clinical responses. The second course of RT was initiated at a median of 150 days following completion of the first course. Side effects were mild: four dogs had chronic ocular conditions necessitating medication, one of which required enucleation. Median survival time (ST) from the first dose of RT was 453 days and 180 days from the first dose of the second course of RT. The following factors were examined but were not significant for survival: total RT dose, dose of the first course of RT, complete resolution of clinical signs, use of either chemotherapy or nonsteroidal anti-inflammatory drugs (NSAIDs), and stage (T1/T2 versus T3/T4). Dogs responded well to reirradiation with a subset experiencing chronic ocular side effects.

2005-01-01

Background Isoflavones are gaining popularity as alternatives to hormone replacement therapy. However, few guidelines exist to inform the public as to an appropriate dose. This case involves a postmenopausal woman who experienced a hypertensive crisis while consuming a high-dose isoflavone supplement as part of a research protocol. Case Presentation The participant was part of a placebo-controlled crossover trial to investigate the potential synergism of the antioxidant activity of soy isoflavones and vitamin C. Upon entry into the study, this healthy, well-nourished, normotensive postmenopausal woman (51 years old), consumed the first of four randomly assigned treatments (500 mg vitamin C plus 5 mg/kg body weight soy isoflavones). During this treatment, the participant's systolic blood pressure spiked to a recorded 226/117 mmHg, necessitating medical intervention and discontinuation of study participation. Two plausible mechanisms for this hypertensive crisis are discussed. Conclusion Due to the availability and increasing popularity of soy supplements, practitioners should be aware of the potential side effects associated with their use. Practitioners counseling clients who are consuming soy isoflavone supplements should advise them that elevated blood pressure may be a potential side-effect to consider and monitor. PMID:15975148

Difficult-to-treat epilepsies and attention-deficit-hyperactivity disorder (ADHD) often co-occur. Because of concerns about the use of stimulants in children with this comorbidity, the impact of ADHD treatment on seizure frequency and severity is not known. This pilot study evaluated the safety and efficacy of methylphenidate in this population. After a 3 month period in which antiepileptic drugs were adjusted, 22 patients recruited from a specialist outpatient clinic for severe epilepsy (16 males, six females; mean age 11 y 2 mo, SD 3 y 2 mo) received methylphenidate for 3 months in an open label, non-controlled trial; four with generalized or multifocal (symptomatic/cryptogenic) epilepsy, one with generalized (idiopathic) epilepsy, 17 with partial (symptomatic/cryptogenic) epilepsy; five with partial seizures only, 17 with primarily or secondarily generalized seizures). Epilepsy, ADHD symptoms, and side effects were assessed using the Swanson, Nolan, and Pelham Questionnaire, the Child Behavior Checklist, the Hague Seizure Severity Scale, and the Side Effects Rating Scale. Methylphenidate significantly improved ADHD. After 3 months of treatment, 73% of patients no longer had clinically significant symptoms. Methylphenidate also reduced seizure severity (9-point median decrease on the Hague Seizure Severity Scale). Seizure frequency increased in four out of 22 patients, but only one patient withdrew from the study for this reason. Most patients experienced no major side effects. These data are among the first showing that low doses of methylphenidate are safe and effective to treat ADHD symptoms in patients with difficult-to-treat epilepsies. Randomized controlled trials are needed to replicate the findings. © The Authors. Developmental Medicine & Child Neurology © 2013 Mac Keith Press.

1986-09-13

To evaluate side effects and patients' assessment of fiberoptic bronchoscopy under local anesthesia, 122 consecutive patients answered questions from an outside interviewer (an experienced psychiatrist) and not from the endoscopists themselves. The effect of premedication with midazolam (5 mg i.m.) and hydrocodonum (15 mg i.m.) was compared in a randomized study. In a multiple choice questionnaire 68% of all patients indicated considerable fear in the days before bronchoscopy. They were more afraid of the possible diagnosis of cancer (23%) than of dyspnea or asphyxiation (14%). Coughing is considered the worst side effect of bronchoscopy by 25% of patients (36% of the endoscopists) followed by dyspnea during insertion of the scope (21%) and discomfort during local anesthesia. Although the patients premedicated with midazolam are more sedated (p = 0.025 by physicians' assessment vs. p = 0.11 in patients' view), they cough more (p = 0.001 vs. p = 0.22) and usually tolerate the examination less well (p = 0.009 vs. p = 0.08) than patients premedicated with hydrocodonum. 42% of patients premedicated with midazolam had anterograde amnesia. Although they did not remember all the unpleasant side effects, only 77% said they would repeat the procedure with the same premedication, compared with 90% of patients premedicated with hydrocodonum (p = 0.08). Before and two hours after premedication the reaction times had not changed (optical sign, Wiener reaction device) and were identical in the two patient groups. At that time 37% of the patients premedicated with midazolam and 27% of those premedicated with hydrocodonum were still sleepy and could not be regarded as fit for any form of travel.

OBJECTIVE: To determine the efficacy of substituting moclobemide, a reversible monoamine oxidase-A inhibitor, for fluoxetine to reverse fluoxetine-induced sexual dysfunction in patients with depression. DESIGN: Prospective open trial. SETTING: Outpatient treatment. PARTICIPANTS: Five patients with depressive disorder who experienced sexual side effects during treatment with standard doses of fluoxetine (20 to 40 mg per day). INTERVENTION: Discontinuation of fluoxetine and replacement with moclobemide (300 to 600 mg per day) after a 2-week washout period. OUTCOME MEASURES: Libido, orgasmic function (in women) or erectile and ejaculatory function (in men), and overall improvement in sexual function during a follow-up period of 2 months to 3 years. RESULTS: Among patients receiving fluoxetine questioned about sexual side effects, 4 (1 man and 3 women) had treatment-related diminished libido with poor orgasmic response or partial erectile failure, and 1 female patient had enhanced sexual desire with intense clitoral stimulation. In all patients, sexual disturbances resolved completely after a 2-week washout period and a switch to treatment with moclobemide. Moclobemide was well tolerated. The antidepressant effect of moclobemide was comparable to that of fluoxetine. CONCLUSIONS: Moclobemide may be preferred as a treatment for depression in patients with fluoxetine-induced sexual dysfunction. PMID:9987207

Chemotherapy side effects (CSE) have a strong impact on patients' quality of life (QOL). To assess patient perceptions of CSE, their impact on QOL and doctor-patient communication regarding these aspects, a survey was conducted among Italian cancer patients. Patients at least 18 years of age, who received chemotherapy, were administered a dedicated questionnaire to assess their point of view on five domains: expectations about CSE and impact on QOL; doctor-patient communication about CSE; treatments to reduce the impact of CSE; sexual life; family relationships/activities and employment. A total of 761 patients participated. CSE had a considerable impact on patient QOL. Nausea/vomiting was the most feared adverse effect before initiating chemotherapy and the one most commonly experienced during treatment. Patients generally reported good doctor-patient communication regarding information about CSE. In almost all cases, the oncologists prescribed an antiemetic treatment, but the incidence of nausea/vomiting was high. Cancer and CSE severely affected sexual life, daily activities and employment. CSE had a strong negative impact on QOL. Good doctor-patient communication is essential. Improving antiemetic strategies may improve QOL. Doctors' ability to inform patients about delicate issues, such as the impact of CSE on sexual life, needs to be improved. © 2016 John Wiley & Sons Ltd.

This study investigated the effect of stethoscope side and tube length on auscultatory blood pressure (BP) measurement. Thirty-two healthy participants were studied. For each participant, four measurements with different combinations of stethoscope characteristics (bell or diaphragm side, standard or short tube length) were each recorded at two repeat sessions, and eight Korotkoff sound recordings were played twice on separate days to one experienced listener to determine the systolic and diastolic BPs (SBP and DBP). Analysis of variance was carried out to study the measurement repeatability between the two repeat sessions and between the two BP determinations on separate days, as well as the effects of stethoscope side and tube length. There was no significant paired difference between the repeat sessions and between the repeat determinations for both SBP and DBP (all P-values>0.10, except the repeat session for SBP using short tube and diaphragm). The key result was that there was a small but significantly higher DBP on using the bell in comparison with the diaphragm (0.66 mmHg, P=0.007), and a significantly higher SBP on using the short tube in comparison with the standard length (0.77 mmHg, P=0.008). This study shows that stethoscope characteristics have only a small, although statistically significant, influence on clinical BP measurement. Although this helps understand the measurement technique and resolves questions in the published literature, the influence is not clinically significant.

Stress radionuclide myocardial perfusion scintigraphy (MPS) using adenosine pharmacological vasodilatation is the preferred method in many centres because of its convenience, safety and speed. It can, however, cause bronchospasm and hence its use is avoided in patients with known or suspected bronchospasm. Owing to service pressures, we use technologist-led adenosine stressing for patients referred for MPS studies. We use a modified adenosine infusion protocol under medical supervision for patients with asthma to prevent and minimize adenosine-induced bronchospasm. In this study, we audited our use of this modified protocol in asthmatic patients and compared the side-effect profile with the standard adenosine protocol used in nonasthmatic patients. We audited 50 consecutive patients with asthma attending our department for stress MPS. All patients were taking regular inhalers+/-oral steroids. Patients who had exacerbation of asthma requiring hospital admission during the preceding 6 months were excluded. Before commencing the infusion, two inhaled puffs of salbutamol were administered. A modified adenosine infusion protocol was used, starting initially at a rate of 70 microg/kg/min and increasing to the standard 140 microg/kg/min within 1 min and then maintained for a further 5 min. Technetium-99m tetrofosmin was injected at 3 min. Blood pressure (BP), pulse rate (PR), oxygen saturation and ECG were monitored before, during and at the end of the infusion. All side effects were recorded. Fifty-eight consecutive patients without asthma were included as controls and received the standard 140 microg/kg/min infusion over 6 min. One hundred and eight patients, 50 with asthma and 58 without asthma, were entered into the study. The test was stopped early in two patients (4%) with asthma and 11 patients (19%) without asthma (chi=5.679; P=0.017). Proportionally, more nonasthmatics developed shortness of breath (SOB) (47 of 58, 81% without asthma vs. 35 of 50, 70% with asthma); however, this did not reach statistical significance (chi=1.788, P=NS). Three out of 50 (6%) patients in the asthma group experienced severe SOB but only one of those 50 patients (2%) developed bronchospasm, manifesting as wheeze. In the nonasthma group, five of 58 patients (8.6%) experienced severe SOB but none developed a wheeze. Less flushing (16 of 50, 32% vs. 36 of 58, 62%; P=0.002), dizziness (12 of 50, 24% vs. 26 of 58, 45%; P=0.023) and neck/throat pain (5 of 50, 10% vs. 16 of 58, 28%; P=0.021) was observed in the modified infusion group with asthma compared with the standard infusion group without asthma. Statistical significance was observed in these three side effects. No significant difference in other side effects was noted. A similar decrease in mean diastolic BP, and an increase in mean PR were observed during the infusion in both asthmatic and nonasthmatic groups. The mean systolic BP decreased significantly in nonasthmatic patients (P<0.001) but not in the asthmatic group. No significant change in oxygen saturation was seen during infusion in the asthmatic group. The modified adenosine infusion protocol with salbutamol premedication can be used in patients with asthma. This protocol resulted in fewer side effects and changes in BP and PR in asthmatic patients compared with nonasthmatic patients who received the standard adenosine infusion.

The COSMOS study was a phase 2a clinical trial that showed high cure rates of genotype 1 chronic hepatitis C (CHC) and a favorable side effect profile using a 12-week regimen of simeprevir + sofosbuvir (SIM + SOF). Given the small number of patients treated with the SIM + SOF regimen in the COSMOS trial, there is uncertainty regarding the efficacy and safety of this combination therapy. We now report our experience with the COSMOS regimen in the multiethnic population of Hawaii, including patients of East Asian ancestry and with decompensated cirrhosis. This study is a retrospective review of 138 patients treated with a fixed dose regimen of SIM 150 mg and SOF 400 mg daily at a single referral center. We collected data on demographics, side effects, laboratory studies and sustained virological response (SVR). Statistical analysis was performed with Stata v8.2 software. Baseline characteristics of the 138 patients initiated with SIM + SOF therapy were: 68.8 % cirrhotic (22.1 % of those Child-Pugh Class B), 37 % Asian, 11.6 % Pacific Islander, 63 % male, mean age 61.3 ± 7.8 years, mean BMI 27.8 ± 6.1 kg/m(2), 26.8 % diabetic, 63.8 % genotype 1a, 44.9 % previously treatment experienced. A total of 100 % of patients that completed therapy (n = 137) had undetectable viral loads at end of treatment (EOT). Twelve patients relapsed post-treatment resulting in an overall 12 week SVR (SVR12) rate of 89.1 %. 95 % of decompensated cirrhotic patients achieved SVR12, compared to 85.3 % of compensated cirrhotic patients and 93 % of non-cirrhotic patients. 92 % of Asian patients achieved SVR12 compared to 87.5 % in non-Asian patients. There were no statistically significant differences in SVR12 between treatment naive and treatment experienced patients (86.8 vs 91.9 %). 87.5 % of post-transplant patients achieved SVR12. The main side effects were headache 16.2 %, fatigue 24.2 %, pruritis 14.1 %; none were >grade 2 in severity. There were no differences in side effect profiles of patients with decompensated cirrhosis. Pruritis only was statistically significant between Asians and non-Asians (22 vs 5.7 %). Trends toward improvement in platelet counts and total bilirubin were noted at 12-weeks post treatment, while improvement in albumin in cirrhotic patients reached statistical significance (3.77-4.01 mg/dL, p = 0.0108). The 12-week fixed dose course of SIM + SOF was well tolerated in a multiethnic population of primarily cirrhotic patients, including those with decompensated disease. This real world trial achieved SVR12 rates comparable to the COSMOS data. Higher incidence of adverse side effects was not observed with an exception of higher rate of pruritis in Asians. The increase in albumin in cirrhotic patients was statistically significant and suggested early improvement in synthetic function following viral eradication. Higher BMI (≥30 kg/m(2)) was the only factor that correlated with post-treatment relapse by multivariate analysis.

Malignancy is a significant public health problem, both globally and in Indonesia. Chemotherapy is one of the modality in malignancy cases. Carboplatin (cis-diammine-cyclobutanedi-carboxylato platinum) is a second-generation platinum compound that has often been used in the management of cases of malignancies. On the other hand, side effects of cytotoxic drugs need to be considered, especially ototoxic effects. Ototoxicity is dysfunction and damage to the structure of the inner ear that has been caused by drugs or other certain chemicals. The aim of this study is to assess ototoxic effects due to the influence of carboplatin in the cases of children with malignancy. This study uses a serial cross-sectional design to evaluate otoacoustic emission (OAE) signal-to-noise ratio (SNR) change as a result of ototoxic effects and risk factors due to the use of ototoxic carboplatin in the Division of Hematology-Oncology of the Department of Pediatrics at Cipto Mangunkusumo General Hospital in Jakarta, where two of 52 studies’ subjects experienced ototoxicity. In the group were receiving chemotherapy, two (5%) of the 40 subjects has experienced ototoxic events characterized by SNR values less than six, whereas SNR values were not less than six in the group that had not received chemotherapy. Risk factors such as gender, age, carboplatin dose, and cycles of chemotherapy did not have a statistically significant relationship to ototoxity.

Observation and modeling of the evolution of an ephemeral storm-induced inlet: Pea Island Breach, North Carolina, USA

The Outer Banks of North Carolina is a wave-dominated barrier island system that has experienced the opening and closure of numerous inlets in the last four centuries. The most recent of those inlets formed after the breaching of Pea Island during Hurricane Irene in 2011. The Pea Island Breach experienced a rapid evolution including episodic curvature of the main channel, rotation of the ebb channel, shoaling, widening by Hurricane Sandy in 2012, and finally closing before the summer of 2013. Studying the life cycle of Pea Island Breach contributes to understanding the behavior of ephemeral inlets in breaching-prone regions. This topic has gained relevance due to rising sea levels, a phenomenon that increases the chances of ephemeral inlet formation during extreme events. This study explores the spatiotemporal effects of tides, waves, and storms on flow velocities and morphology of the breach by means of remotely sensed data, geospatial metrics, and a numerical model. The combined use of observations and results from modeling experiments allowed building a conceptual model to explain the life cycle of Pea Island Breach. Wave seasonality dominated the morphological evolution of the inlet by controlling the magnitude and direction of the longshore current that continuously built transient spits at both sides of the breach. Sensitivity analysis to external forcings indicates that ocean waves can modify water levels and velocities in the back barrier. Sound-side storm surge regulates overall growth rate, duration, and decay of peak water levels entering the inlet during extreme events.

To determine how common it is for parents to give natural health products (NHPs) to their children, which NHPs are being used, why they are being used, and parents' assessments of the benefits and side effects of NHPs. Survey. Newfoundland and Labrador. Parents waiting in their family doctors' offices. Parent and child demographic characteristics; pediatric chronic medical conditions affecting the children; prescribed medications, over-the-counter medications, and NHPs used by the children; why the medications and NHPs were being used, the dose, and parents' assessments of the effectiveness and side effects; and where parents had heard about the NHPs, whether they had told their physicians that the children were taking the products, and where they had obtained the products. A total of 202 (53.4%) of the 378 eligible adults who were approached completed the survey. This represented 333 children. Mean (SD) age of the children was 5.1 (3.3) years. Overall, 28.7% of parents reported using nonvitamin NHPs for their children. A total of 137 children (41.1%) had taken NHPs (including vitamins); 61.1% of the NHPs being used were vitamins. The remainder fell under teas (primarily chamomile and green teas), echinacea, fish or omega-3 oils, and a large category of "other" products. These NHPs were most commonly used to improve general health, improve immunity, and prevent colds and infections. Approximately half of the parents (51.7%) believed their children had benefited from taking NHPs, and 4.4% believed their children had experienced adverse side effects. Slightly less than half of the parents (45.0%) had informed their physicians that their children were taking NHPs. Overall, 45.5% of parents attending physicians' offices reported using NHPs in their children. If vitamins are not included in the definition of NHPs, this rate drops to 28.7%. Parents most commonly use NHPs to maintain the general health of their children, to prevent colds, and to boost children's immune systems. About half of the parents believed the NHPs helped, very few had noticed any side effects, and approximately half had informed their physicians that they were giving their children NHPs.

Although asthma self-management plans are widely recommended as essential in the long-term treatment of adult asthma, there have been few studies examining their use. Our objective was to assess the effect of a "credit card" adult asthma self-management plan in a community experiencing major health problems from asthma, by means of a before and after intervention trial of the efficacy of the "credit card" plan, when introduced through community-based asthma clinics. The participants were 69 Maori people with asthma. The "credit card" plan consisted of written guidelines for the self-management of asthma, based on self-assessment of asthma severity, printed on a plastic card. On one side, management guidelines were based on the interpretation of peak expiratory flow rate (PEFR) recordings, whilst the reverse side was based on symptoms. The outcome measures used were before and after comparison of markers of asthma morbidity and requirement for acute medical treatment; and a structured questionnaire assessing the acceptability and use of the credit card plan. Following the introduction of the plan, the mean PEFR increased from 347 to 389 l.min-1, the percentage of nights woken fell from 30.4 to 16.9%, and the number of days "out of action" fell from 3.8 to 1.7%. The requirements for acute medical treatment also fell during the intervention period. Most participants commented favourably on the content and usefulness of the plan. In the situation of worsening asthma, 28% of subjects found the peak flow side of the card most helpful, 7% the symptoms side, and 48% found both sides equally helpful.(ABSTRACT TRUNCATED AT 250 WORDS)

Asymmetric pelvic bracing and altered kinematics in patients with posterior pelvic pain who present with postural muscle delay.

The purpose of the study was to examine the muscle activity and hip-spine kinematics in a group of individuals diagnosed with posterior pelvic girdle pain and confirmed postural muscle delay during a repeated fast hip flexion task. Twenty-four (12 pain and 12 control) age and sex matched participants performed a repeated fast hip flexion task to auditory signal. Surface EMG activity in the external and internal oblique, the multifidus, the gluteus maximus and biceps femoris in the stance-limb was examined for onset timing and EMG integral. Sagittal plane hip (swing limb) and spine kinematics were examined for group and side differences over the repeated trials. While the pain group lacked significant feedforward muscle activity they displayed higher muscle activity at movement onset in the biceps femoris bilaterally (p<0.05) as well as the external oblique (p<0.05) during motion of the symptomatic side. Furthermore, the pain group experienced asymmetrical spinal range of motion with increased motion on the contralateral side (p<0.001) and reduced flexion velocity on the symptomatic side (p<0.001). The findings support previous hypotheses regarding the effect of increased biceps activity on pelvic control during lumbo-pelvic rotation. Further, there appears to be a symptom led strategy for bracing the innominate through opposing tension in the biceps and external oblique during movement of the painful side. Such asymmetrical pelvic girdle bracing may be a strategy to increase the stability of the pelvis in light of the failed load transfer mechanism. Putatively, this strategy may increase the mechanical stress on the sacroiliac joint exacerbating pain complaints. Copyright © 2014 Elsevier Ltd. All rights reserved.

Physical inactivity has been shown to exacerbate negative side effects experienced by pediatric patients undergoing cancer therapy. Exercise interventions are being created in response. This review summarizes current exercise intervention data in the inpatient pediatric oncology setting. Two independent reviewers collected literature from three databases, and analyzed data following the PRISMA statement for systematic reviews and meta-analyses. Ten studies were included, representing 204 patients. Good adherence, positive trends in health status, and no adverse events were noted. Common strategies included individual, supervised, combination training with adaptability to meet fluctuating patient abilities. We recommend that general physical activity programming be offered to pediatric oncology inpatients. © 2017 Wiley Periodicals, Inc.

As practices of altered states of consciousness (ASC) have become more widely used among psychotherapists who have become aware of the limitations of psychoanalytic, educational and behavioral approaches, negative aspects ('Makyo') of ASC have drawn their special attention. For the purpose of controlling or preventing these side-effects, (1) the problem of indication is most important, (2) and evaluation of the patient's personality is indispensable, (3) preparatory education about ASC methods and (4) guidance by experienced leaders are most helpful, (5) appropriate use of tranquilizers and (6) the mere presence of a supportive therapist at the place of practice can also be helpful.

Effects of simulated space environment on Skylab parasol material

1974-01-01

A material consisting of ripstop nylon bonded to the Mylar side of aluminized Mylar film was used to construct the first Skylab parasol. The mechanical properties of elongation and tensile strength and the radiative properties of solar absorptance and thermal emittance were measured before and after exposure to simulated solar radiation at intensities of 1.0 and 3.5 solar constants for exposure times as long as 947 hours or 3316 equivalent solar hours. The accelerated testing indicated more severe degradation than was experienced in the real-time test (1 solar constant). The results predicted that this material could have given satisfactory performance throughout the planned lifetime of the Skylab workshop.

To evaluate the safety and efficacy of vapocoolants (topical skin refrigerants) to induce skin anesthesia and relieve patient anxiety and pain prior to cosmetic botulinum injections. A paired (split-face) design was used in 52 patients where patient side (left vs. right) was randomized to receive either vapocoolant spray or no treatment control to test the study hypothesis of better anesthetic efficacy of vapocoolant spray versus no treatment control. A pain and anxiety questionnaire was administered before, during, and after the injections. A considerable percentage of patients either expected pain (35% of naïve patients expected moderate pain) or had experienced pain from their prior treatment (35% had experienced moderate pain). Among naïve patients, 15% had moderate or severe anxiety and among experienced patients, 31% had moderate anxiety. Pain was a factor in delaying the scheduling of cosmetic botulinum toxin treatments in 19% of naïve patients and 31% of experienced patients. Pain reported from actual injections was higher than what was anticipated prior to treatment. There was a significant reduction in pain at injection sites treated with vapocoolant (p < 0.001, paired t test). Overall, 67% of all patients reported that the vapocoolant method had less pain than no anesthesia and 54% preferred vapocoolant for their next treatment. Overall, 6% of all patients would schedule their next botulinum toxin treatment sooner if vapocoolant were available. Vapocoolants represent a safe and effective means to reduce patient discomfort and anxiety before and during botulinum toxin type A treatments for glabellar area indications.

Dental implant failure and insufficient osseointegration are proven results of mechanical and thermal damage during the surgery process. We herein performed a comparative study of a less invasive single-step drilling preparation protocol and a conventional multiple drilling sequence. Accuracy of drilling holes was precisely analyzed and the influence of different levels of expertise of the handlers and additional use of drill template guidance was evaluated. Six experimental groups, deployed in an osseous study model, were representing template-guided and freehanded drilling actions in a stepwise drilling procedure in comparison to a single-drill protocol. Each experimental condition was studied by the drilling actions of respectively three persons without surgical knowledge as well as three highly experienced oral surgeons. Drilling actions were performed and diameters were recorded with a precision measuring instrument. Less experienced operators were able to significantly increase the drilling accuracy using a guiding template, especially when multi-step preparations are performed. Improved accuracy without template guidance was observed when experienced operators were executing single-step versus multi-step technique. Single-step drilling protocols have shown to produce more accurate results than multi-step procedures. The outcome of any protocol can be further improved by use of guiding templates. Operator experience can be a contributing factor. Single-step preparations are less invasive and are promoting osseointegration. Even highly experienced surgeons are achieving higher levels of accuracy by combining this technique with template guidance. Hereby template guidance enables a reduction of hands-on time and side effects during surgery and lead to a more predictable clinical diameter.

Bilateral self-expandable metallic stent (SEMS) placement for the management of unresectable malignant hilar biliary obstruction (UMHBO) is technically challenging to perform using the existing metallic stents with thick delivery systems. The recently developed 6-Fr delivery systems could facilitate a single-step simultaneous side-by-side placement through the accessory channel of the duodenoscope. The aim of this study was to evaluate the feasibility of this procedure. Between May and September 2013, 13 consecutive patients with UMHBO underwent a single-step simultaneous side-by-side placement of SEMS with the 6-Fr delivery system. The technical success rate, stent patency, and rate of complications were evaluated from the prospectively collected database. Technical success was achieved in 11 (84.6%, 95% confidence interval [CI]: 57.8-95.8) patients. The median procedure time was 25 min. Early and late complications were observed in 23% (one segmental cholangitis and two liver abscesses) and 15% (one segmental cholangitis and one cholecystitis) patients, respectively. Median dysfunction free patency was 263 days (95% CI: 37-263). Five patients (38%) experienced stent occlusion that was successfully managed by endoscopic stent placement. A single-step simultaneous side-by-side placement of SEMS with a 6-Fr delivery system was feasible for the management of UMHBO. © 2014 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

To describe profound hearing loss associated with hydrocodone overuse and the successful rehabilitation of these patients with cochlear implantation. Retrospective review. A tertiary otologic referral center. Twelve patients with rapidly progressive hearing loss and a concurrent history of hydrocodone overuse. Comprehensive medical histories, physical findings, audiometric tests, and, in those patients undergoing cochlear implantation, postimplantation performance data were reviewed. Clinical characteristics of hydrocodone-related hearing loss and open set word and sentence performance in those patients undergoing cochlear implantation. Hydrocodone overuse was associated with rapidly progressive sensorineural hearing loss in 12 patients. In four patients the initial presentation was unilateral, and two of the patients experienced vestibular symptoms. None of the 12 patients experienced improved thresholds after high-dose prednisone. Seven of the eight patients undergoing cochlear implantation have demonstrated early success with their devices. Hydrocodone is frequently prescribed in combination with acetaminophen for the relief of pain and has a side effects profile similar to other medications in its class. Although not described previously, overuse or abuse can be associated with a rapidly progressive sensorineural hearing loss. These patients can be successfully rehabilitated with cochlear implantation.

Anxiety is a commonly reported side-effect of psychostimulant treatment. Our goal was to quantify the risk of anxiety as a side effect of psychostimulant treatment for attention-deficit/hyperactivity disorder (ADHD). We conducted a PubMed search to identify all double-blind, randomized, placebo-controlled trials examining the efficacy of psychostimulant medications in the treatment of children with ADHD. We used a fixed-effects meta-analysis to examine the risk ratio of anxiety reported as a side effect in children treated with psychostimulants compared with those treated with placebo. We used stratified subgroup analysis and meta-regression to examine the effects of stimulant type, dosage, duration of use, and trial design on the measured risk of anxiety. We identified 23 studies involving 2959 children with ADHD for inclusion in our meta-analysis. The risk of anxiety associated with psychostimulant treatment was significantly lower than that experienced with placebo (relative risk [RR] = 0.86 [95% CI: 0.77, 0.95], z = -2.90, p < 0.05). Higher doses of psychostimulants were associated with a reduced measured risk of anxiety of psychostimulants when compared with placebo (β = -0.0039 [95% CI: -0.00718, -0.00064], z = -2.34, p = 0.019). Meta-analysis suggests that treatment with psychostimulants significantly reduced the risk of anxiety when compared with placebo. This finding does not rule out the possibility that some children experience increased anxiety when treated with psychostimulants, but suggests that those risks are outweighed by the number of children who experience improvement in anxiety symptoms (possibly as a secondary effect of improved control of ADHD symptoms). Clinicians should consider rechallenging children with ADHD who report new-onset or worsening anxiety with psychostimulants, as these symptoms are much more likely to be coincidental rather than caused by psychostimulants.

Alopecia areata is a common hair loss condition that is often emotionally devastating for patients. There is a paucity of effective treatments available. Hydroxychloroquine has been reported as variably effective in inducing significant hair regrowth in adults with alopecia areata. The objective of this retrospective study was to assess the benefit and tolerability of hydroxychloroquine in pediatric alopecia areata. We conducted a retrospective review of nine children with a history of alopecia areata treated with hydroxychloroquine. Clinical data were obtained from patients treated at two tertiary care centers in the United States between July 1, 2013, and July 1, 2015. Alopecia scores of five patients improved by 6 months of treatment. Four patients experienced no improvement from baseline evaluation. The most common side effect associated with treatment was gastrointestinal intolerance and headache. This retrospective series suggests that hydroxychloroquine can be considered as a treatment option for alopecia areata in children. © 2018 Wiley Periodicals, Inc.

2013-01-01

Inherent in many reproductive health and family planning programmes is the problematic assumption that the body, its processes, and modifications to it are universally experienced in the same way. This paper addresses contraceptive knowledge and beliefs among Mexican-origin women, based upon data gathered by the qualitative component of the Border Contraceptive Access Study. Open-ended interviews explored the perceived mechanism of action of the pill, side effects, non-contraceptive benefits, and general knowledge of contraception. Findings revealed complex connections between traditional and scientific information. Use of medical terms (“hormone”) illustrated attempts to integrate new information with existing knowledge and belief systems. Conclusions address concerns that existing information and services may not be sufficient if population-specific knowledge and beliefs are not assessed and addressed. Findings can contribute to the development of effective education, screening, and reproductive health services. PMID:23464742

Loss of personal memories experienced prior to receiving electroconvulsive therapy is common and distressing and in some patients can persist for many months following treatment. Improved understanding of the relationships between individual patient factors, electroconvulsive therapy treatment factors, and clinical indicators measured early in the electroconvulsive therapy course may help clinicians minimize these side effects through better management of the electroconvulsive therapy treatment approach. In this study we examined the associations between the above factors for predicting retrograde autobiographical memory changes following electroconvulsive therapy. Seventy-four depressed participants with major depressive disorder were administered electroconvulsive therapy 3 times per week using either a right unilateral or bitemporal electrode placement and brief or ultrabrief pulse width. Verbal fluency and retrograde autobiographical memory (assessed using the Columbia Autobiographical Memory Interview - Short Form) were tested at baseline and after the last electroconvulsive therapy treatment. Time to reorientation was measured immediately following the third and sixth electroconvulsive therapy treatments. Results confirmed the utility of measuring time to reorientation early during the electroconvulsive therapy treatment course as a predictor of greater retrograde amnesia and the importance of assessing baseline cognitive status for identifying patients at greater risk for developing later side effects. With increased number of electroconvulsive therapy treatments, older age was associated with increased time to reorientation. Consistency of verbal fluency performance was moderately correlated with change in Columbia Autobiographical Memory Interview - Short Form scores following right unilateral electroconvulsive therapy. Electroconvulsive therapy treatment techniques associated with lesser cognitive side effects should be particularly considered for patients with lower baseline cognitive status or older age. © The Author 2015.

Background Disease modifying drugs help control the course of relapsing remitting multiple sclerosis (RRMS); however, good adherence is needed for long-term outcomes. Objective To evaluate patient adherence to treatment with subcutaneous interferon beta-1a using RebiSmart® and assess injection-site reactions and treatment satisfaction. Methods This prospective, single-arm, open-label, noninterventional multicenter Phase IV trial included disease modifying drug-experienced mobile patients with RRMS. Adherence was measured over 12 weeks. Items 13–23, 35, 37, and 38 of the Multiple Sclerosis Treatment Concerns Questionnaire (injection-site reactions and treatment satisfaction) were recorded at 12 weeks. Results Sixty patients were recruited (mean age 43.7 [±SD 7.9] years; 83% female; mean years since multiple sclerosis diagnosis 6.7 [SD 4.5]). Adherence data were obtained in 54 patients only due to technical problems with six devices. Over 12 weeks, 89% (n=48) of patients had ≥90% adherence to treatment. Most patients experienced mild influenza-like symptoms and injection-site reactions, and global side effects were minimal. Most patients (78%) rated the convenience as the most important aspect of the device, and most experienced no or mild pain. Conclusion RRMS patients treated with subcutaneous interferon beta-1a, administered with RebiSmart, demonstrated generally good adherence, and the treatment was generally well tolerated.

Background The use of intraoperative neuromonitoring (IONM) provides surgeons with real time information about recurrent laryngeal nerves (RLN) functional integrity. Hence, allowing them to modify the initially scheduled bilateral procedure, to a two-stage thyroidectomy in cases of loss of signal (LOS) on the first side of resection resulting in minimization of bilateral RLN injury. The purpose of our study was to present our results since the implementation of the above mentioned process in both malignant and benign thyroid disease. Methods We conducted a retrospective, observational cohort study of prospectively collected data from all patients who underwent a scheduled total thyroidectomy with or without neck dissection in our Department over the last 4 years [2013–2016]. From the 1,138 patients who received surgical treatment during that period, 284 were excluded since they did not meet the criteria. Exclusion criteria involved previous neck operation, parathyroid surgery, pre-existing vocal cord palsy (VCP) and unilateral surgery. A total of 854 patients were eligible for our study. All patients were subjected to pre- and postoperative indirect laryngoscopy by the same experienced ENT specialist team and all the surgeries were performed by the same experienced team. The whole procedure followed the International Neural Monitoring Study Group’s (INMSG) Guideline Statement. Results We experienced 70 cases (70/854, 8.2%) with postoperative VCP. Two of them (0.23%) had permanent VCP and the rest of those patients (7.97%) experienced transient VCP. Twenty-three (2.7%) patients were candidates for staged thyroidectomy after LOS on the first side of resection, including ten patients with papillary or medullary thyroid carcinoma and one with toxic multinodular goiter (MNG). Of those patients, 22 incidents of VCP (95.7%) have recovered within two months and one of them persisted for more than six months (permanent VCP). We did not experience any permanent bilateral RLN palsy after the implementation of the staged procedure. Conclusions Staged thyroidectomy seems a very attractive and promising procedure for both patient and surgeon, since it nearly eliminates one of the most fearful complications in thyroid surgery. We suggest staged thyroidectomy in all cases with first side of resection signal loss, even in malignancies, since the benefits are much more than the disabilities in a patient’s morbidity and quality of life.

The aim of this 'split-mouth design' trial was to evaluate the effect of the nano amorphous calcium phosphate (NACP) containing composite on enamel mineral contents and streptococcus mutans population in fixed orthodontic patients. Randomized, prospective, single-center controlled trial. Twenty-four patients between the ages of 13-18 years participated in this study. The control and test sides were randomly selected by a coin toss (1:1 ratio). On the control side orthodontic brackets were bonded on the buccal surfaces of upper premolars and laterals using an orthodontic composite (Transbond XT), and on the study side NACP-containing composite was used. Outcome measures were the mineral content around the brackets and S.mutans count. The later were calculated in the plaque around the brackets by real-time PCR at 3 months, and 6 months after the initiation of treatment. All stages of the study were blind using coding system. Paired t-test and repeated measurements were used for data analysis. In the third and sixth month, the bacterial population was significantly lower in the study side than the control side (P = 0.01 and 0.000).The mineral content of the study side was significantly higher than the controls, 6 months after brocket bonding (P = 0.004). There were no significant differences between the premolars and lateral teeth for all measurements. This research was performed in a single-center by one experienced clinician. NACP-containing composites have the potential to inhibit mineral content loss and S.mutans colonization around orthodontic brackets during fixed orthodontic treatments. This trial was not registered. The protocol was not published before trial commencement. © The Author 2016. Published by Oxford University Press on behalf of the European Orthodontic Society. All rights reserved.

Premenstrual syndrome (PMS) affects most women during their reproductive life. Headache is regarded as a typical symptom of PMS and, close to menses, migrainous women could experience their worst migraine attacks. Vitex agnus-castus (VAC) is a phytopharmaceutical compound, considered worldwide to be a valid tool to treat PMS. Aim of this study is to explore if headache is ameliorate in migrainous women treated with VAC for PMS by an open-label clinical observation. Migrainous women with PMS were enrolled in the study and advised to assume a treatment with VAC (40 mg/day) for PMS for a 3-month period. Effects both on PMS and headache were assessed. Out of 107 women, 100 completed the 3-month treatment for PMS. Out of them, 66 women reported a dramatic reduction of PMS symptoms, 26 a mild reduction, and 8 no effect. Concerning migraine, 42 % of patients experienced a reduction higher than 50 % in frequency of monthly attacks, and 57 % of patients experienced a reduction higher than 50 % in monthly days with headache. No patients reported remarkable side effects. Pending a placebo-controlled trial to confirm our results, we observed that the use of VAC in migrainous women affected by PMS resulted to be safe and well tolerated, and may positively influence the frequency and duration of migraine attacks.

Adherence to malaria prophylaxis among Peace Corps Volunteers in the Africa region, 2013.

Landman, Keren Z; Tan, Kathrine R; Arguin, Paul M

2015-01-01

Although malaria can be prevented with prophylaxis, it is diagnosed in over 100 Africa-region Peace Corps Volunteers annually. This suggests that prophylaxis non-adherence is a problem in these non-immune travelers. We investigated Volunteers' knowledge, attitudes, and practices regarding prophylaxis using an internet-based survey during August 19-September 30, 2013. Adherence was defined as taking doxycycline or atovaquone-proguanil daily, or taking mefloquine doses no more than 8 days apart. The survey was sent to 3248 Volunteers. Of 781 whose responses were analyzed, 514 (73%) reported adherence to prophylaxis. The most common reasons for non-adherence were forgetting (n = 530, 90%); fear of long-term adverse effects (LTAEs; n = 316, 54%); and experiencing adverse events that Volunteers attributed to prophylaxis (n = 297, 51%). Two hundred fourteen (27%) Volunteers reported not worrying about malaria. On multivariate analysis controlling for sex and experiencing adverse events Volunteers attributed to prophylaxis, the factor most strongly associated with non-adherence was being prescribed mefloquine (OR 5.4, 95% confidence interval 3.2-9.0). We found moderate adherence and a prevailing fear of LTAEs among Volunteers. Strategies to improve prophylaxis adherence may include medication reminders, increasing education about prophylaxis safety and malaria risk, and promoting prompt management of prophylaxis side effects.

In this study we analyzed the pattern recall skills of talented soccer players by means of two innovative methods of analysis and gaze behavior data. Twenty-two young female soccer players watched video clips of 3 vs. 3 small-sided games and, after occlusion, had to reproduce the positions of the players. Recall performance was measured by calculating the spatial error of the recalled player positions at the moment of occlusion and at consecutive 33ms increments. We analyzed player positions relative to each other, by assessing geometric pattern features in terms of angles between players, and we transformed the data into real-world coordinates to exclude the effects of the 2D perspective in the video clips. The results showed that the participants anticipated the movements of the patterns. In real-world coordinates, the more experienced players anticipated the pattern further in advance than the less experienced players and demonstrated a higher search rate, a shorter fixation duration and a higher fixation order. The differences in recall accuracy between the defensive and offensive elements were not consistent across the methods of analysis and, therefore, we propose that perspective effects of the video clip should be taken into account in further research.

In constant frequency-frequency modulation (CF-FM) bats, the CF-FM echolocation signals include both CF and FM components, yet the role of such complex acoustic signals in frequency resolution by bats remains unknown. Using CF and CF-FM echolocation signals as acoustic stimuli, the responses of inferior collicular (IC) neurons of Hipposideros armiger were obtained by extracellular recordings. We tested the effect of preceding CF or CF-FM sounds on the shape of the frequency tuning curves (FTCs) of IC neurons. Results showed that both CF-FM and CF sounds reduced the number of FTCs with tailed lower-frequency-side of IC neurons. However, more IC neurons experienced such conversion after adding CF-FM sound compared with CF sound. We also found that the Q 20 value of the FTC of IC neurons experienced the largest increase with the addition of CF-FM sound. Moreover, only CF-FM sound could cause an increase in the slope of the neurons' FTCs, and such increase occurred mainly in the lower-frequency edge. These results suggested that CF-FM sound could increase the accuracy of frequency analysis of echo and cut-off low-frequency elements from the habitat of bats more than CF sound.

We conducted a double-blind, placebo-controlled, crossover study evaluating the analgesic efficacy of vaporized cannabis in subjects, the majority of whom were experiencing neuropathic pain despite traditional treatment. Thirty-nine patients with central and peripheral neuropathic pain underwent a standardized procedure for inhaling medium-dose (3.53%), low-dose (1.29%), or placebo cannabis with the primary outcome being visual analog scale pain intensity. Psychoactive side effects and neuropsychological performance were also evaluated. Mixed-effects regression models demonstrated an analgesic response to vaporized cannabis. There was no significant difference between the 2 active dose groups' results (P > .7). The number needed to treat (NNT) to achieve 30% pain reduction was 3.2 for placebo versus low-dose, 2.9 for placebo versus medium-dose, and 25 for medium- versus low-dose. As these NNTs are comparable to those of traditional neuropathic pain medications, cannabis has analgesic efficacy with the low dose being as effective a pain reliever as the medium dose. Psychoactive effects were minimal and well tolerated, and neuropsychological effects were of limited duration and readily reversible within 1 to 2 hours. Vaporized cannabis, even at low doses, may present an effective option for patients with treatment-resistant neuropathic pain. The analgesia obtained from a low dose of delta-9-tetrahydrocannabinol (1.29%) in patients, most of whom were experiencing neuropathic pain despite conventional treatments, is a clinically significant outcome. In general, the effect sizes on cognitive testing were consistent with this minimal dose. As a result, one might not anticipate a significant impact on daily functioning. Published by Elsevier Inc.

Liarozole (R75251) in hormone-resistant prostate cancer patients.

PubMed

Dijkman, G A; Fernandez del Moral, P; Bruynseels, J; de Porre, P; Denis, L; Debruyne, F M

1997-09-15

Liarozole is an imidazole derivative that has been identified as an inhibitor of the cytochrome P450-dependent all-trans retinoid acid (RA) breakdown. RA is one of the principal endogenous compounds that controls growth and differentiation of epithelial tissues in mammals. Fifty-five patients with hormone-resistant prostate cancer in progression, following at least first-line androgen ablation therapy, were evaluated. Thirty-one patients were treated with liarozole 300 mg b.i.d., while 24 patients started with 150 mg b.i.d., which was increased to 300 mg b.i.d. after 4 or 8 weeks. Two patients were not evaluable because they withdrew after initial consent. The WHO performance status was 0 (n = 18), 1 (n = 22), 2 (n = 17), and 3 (n = 6). Most patients (80%) used analgesics. For 11 out of the 53 patients, treatment lasted less than 1 month (they were therefore not evaluable for response) due to: poor compliance (n = 1); early death (n = 3); side-effects (n = 2); and decline of physical condition and continuous progression (n = 4). One patient refused to report for follow-up. In all responders, except one, the dose was increased to 300 mg b.i.d. In 23 of the 42 patients evaluable for response, the pain score improved. In 5 patients the pain score had reduced from 2 or 3 to 0. In 11 out of the 42 patients there was a 1-point improvement of WHO performance status. The prostatic-specific antigen (PSA) response rate was 41%; 15 out of 42 evaluable patients presented a decrease of > or = 50%, whereas PSA normalized in 2 further patients. Most of the side effects mimicked retinoid acid toxicity: cutaneous manifestations (such as dry skin, dry lips, sticky skin, brittle nails, erythema, or itch). All patients experienced one or more of these side effects. Other side effects include nausea, fatigue, and slight alopecia. Liarozole can be an enrichment of the therapeutic armamentarium for treatment of hormone-resistant prostate cancer patients after first-line androgen ablation therapy without serious toxicity.

Opioid-Induced Bowel Dysfunction

PubMed Central

Cheng, Vivian; Lembo, Anthony

2013-01-01

Opioid-induced bowel dysfunction (OIBD) is a potentially debilitating side effect of chronic opioid use. It refers to a collection of primarily gastrointestinal motility disorders induced by opioids, of which opioid-induced constipation (OIC) is the most common. Management of OIBD is difficult, and affected patients will often limit their opioid intake at the expense of experiencing more pain, to reduce the negative impact of OIBD on their quality of life. Effective pharmacologic therapy for OIC is considered an unmet need and several agents have recently been given priority review and approval for OIC. Furthermore, multiple agents currently in development show promise in treating OIC without significant impact on analgesia or precipitation of withdrawal symptoms. The approval and availability of such medications would represent a significant improvement in the management of OIC and OIBD in patients with chronic pain. PMID:23900996

To assess the impact of different repeated-high-intensity-effort (RHIE) bouts on player activity profiles, skill involvements, and neuromuscular fatigue during small-sided games. 22 semiprofessional rugby league players (age 24.0 ± 1.8 y, body mass 95.6 ± 7.4 kg). During 4 testing sessions, they performed RHIE bouts that each differed in the combination of contact and running efforts, followed by a 5-min off-side small-sided game before performing a second bout of RHIE activity and another 5-min small-sided game. Global positioning system microtechnology and video recordings provided information on activity profiles and skill involvements. A countermovement jump and a plyometric push-up assessed changes in lower- and upper-body neuromuscular function after each session. After running-dominant RHIE bouts, players maintained running intensities during both games. In the contact-dominant RHIE bouts, reductions in moderate-speed activity were observed from game 1 to game 2 (ES = -0.71 to -1.06). There was also moderately lower disposal efficiency across both games after contact-dominant RHIE activity compared with running-dominant activity (ES = 0.62-1.02). Greater reductions in lower-body fatigue occurred as RHIE bouts became more running dominant (ES = -0.01 to -1.36), whereas upper-body fatigue increased as RHIE bouts became more contact dominant (ES = -0.07 to -1.55). Physical contact causes reductions in running intensity and the quality of skill involvements during game-based activities. In addition, the neuromuscular fatigue experienced by players is specific to the activities performed.

Purpose. To evaluate the treatment effect and side effect of Shenqi Fuzheng Injection (SFI) on alleviating transient worsening of myasthenia gravis (MG) symptoms caused by high-dose steroids pulse therapy. Methods. Sixty-six consecutive patients with MG were randomly divided into two groups: the treatment group treated with SFI and methylprednisolone pulse therapy (MPT) and the control group treated with MPT alone. The severity of MG before, during, and after MPT and the duration of transient worsening (TW) were evaluated and compared with the clinical absolute scoring (AS) and relative scoring (RS) system. Results. Twenty-nine patients experienced TW in each group. At TW, the AS was significantly increased (P < 0.000) in both groups compared with baseline data, with the AS increase in the treatment group (16.8 ± 2) significantly smaller (P < 0.05) than in the control group (24.9 ± 2.5). At the end of the treatment course, the AS for the treatment group was significantly decreased (7.5 ± 0.9) compared with at TW, although no significant difference compared with the control (9.7 ± 1.1). The TW lasted 1–6 days (mean 3.7) for the treatment group, significantly shorter (P < 0.05) than 2–12 days (mean 7.8) for the control. The RS for the treatment group at the end of treatment was 43.8%–100% (mean 76.8% ± 2.6%), significantly better than the control group: 33.3%–100% (mean 67.2 ± 3.6%). Slight side effects (18.75%) included maldigestion and rash in the treatment group. Conclusion. SFI has a better treatment effect and few side effects and can alleviate the severity and shorten the duration of the transient worsening of MG during steroids pulse therapy. PMID:24348721

Smokeless tobacco cessation: report of a preliminary trial using nicotine chewing gum.

Sinusas, K; Coroso, J G

1993-09-01

Smokeless tobacco use is a major public health hazard whose incidence is increasing, particularly among male adolescents. Little research has been done on cessation programs designed to assist smokeless tobacco users in ending their habit. There have been no studies on the use of nicotine polacrilex chewing gum as an adjunct to cessation. Fourteen of 88 male smokeless tobacco users in a professional baseball organization enrolled in a cessation program and were followed for up to 12 months. The program consisted of two support group sessions at the spring training camp followed by adjunctive use of nicotine polacrilex chewing gum during the baseball season as monitored by the athletic trainers. At 2 to 4 months, only 3 of 14 participants were completely abstinent from smokeless tobacco. Follow-up data at 6 to 12 months revealed that only one participant was abstinent. The 14 ballplayers experienced various side effects of nicotine chewing gum: bad taste (6), nausea (4), headache (4), jaw discomfort (3), and dizziness (1). Despite these side effects, 11 of the 14 participants replied that they would recommend the gum to others trying to quit. Most participants (10) felt that quitting the smokeless tobacco habit was "very difficult." We conclude that nicotine chewing gum as an adjunct to smokeless tobacco cessation had limited effectiveness. Further study on smokeless tobacco cessation methods is needed.

A fixed combination of 0.1% hydroxypinacolone retinoate (synthetic esther of 9-cis-retinoic acid), 1% retinol in glycospheres and 2% papain in glycospheres in aqueous gel has been recently introduced into the Italian market in order to reduce the incidence and severity of irritant contact dermatitis caused by topical retinoids, without compromising their efficacy. Primary objectives of this sponsor-free, pilot, open, multicenter study were to evaluate the efficacy and tolerability of this gel in patients with comedonal-papular, mild to moderate acne of the face. Ninety-eight Caucasian patients (28 males and 70 females), with an age ranging from 15 to 40 years, were treated with the gel once daily for 12 weeks. Acne severity and treatment efficacy were evaluated by means of the Global Acne Grading System (GAGS) and lesions count. Ninety-four patients were considered evaluable. A 41% mean reduction in the GAGS score was observed; a 40.8% mean reduction of total lesions was recorded; 15.3% of patients experienced mild to moderate local side effects (dryness, peeling, erythema, burning). No patients stopped the treatment because of these side effects. This study, based on a high number of evaluable patients, demonstrates that this fixed combination is an effective and safe option for the treatment of comedonal-papular, mild to moderate acne of the face. A controlled clinical study is necessary to confirm these data.

Tranexamic acid (TXA) is an antifibrinolytic agent that has shown promise in reducing blood loss during total hip arthroplasty (THA). Several studies have reported side effects of high-dose TXA administration, including myocardial infarction (MI), thromboembolic events, and seizures. These possible side effects have prevented the widespread adoption of TXA in the surgical community. We conducted a retrospective chart review of 564 primary and revision THAs performed at a single academic center. Surgical patients received either no TXA or 1 g IV TXA at the beginning of surgery followed by a second bolus just before the surgical wound closure, at the surgeon's discretion. We analyzed differences in hemoglobin (Hb), hematocrit (Hct), estimated blood loss (EBL), and adverse events in patients receiving TXA versus patients not receiving TXA up to 2 days following surgery. Significantly higher Hb and Hct values were found across all time points among patients undergoing primary posterior or revision THA who had received TXA. In addition, transfusion rates were significantly decreased in both primary posterior THAs and revision THAs when TXA was administered. Patients who received TXA experienced significantly fewer adverse events than those who did not for all surgery types. Administration of low-dose intravenous (IV) and intra-articular (IA) TXA does not appear to increase rates of adverse events and may be effective in minimizing blood loss, as reflected by Hb and Hct values following THA.

The side effects of oncological treatment, which appear during or after therapy, are sometimes very annoying for patients and are not adequately treated by physicians. Among the symptoms experienced by breast cancer patients are hot flushes, which result from a natural or cancer therapy-induced menopause. The intensity of hot flushes in breast cancer patients may be more severe than those experienced by women undergoing a natural menopause. Taking into account the incidence of breast cancer and long-lasting hormone-suppression therapies, the problem of hot flushes will affect many women. Hormonal replacement therapy, the most effective therapeutic means for alleviating hot flushes, is usually contraindicated for breast cancer patients. For intense and severe hot flushes, pharmacological treatment using agents from a group of selective serotonin reuptake inhibitors and serotonin and norepinephrine reuptake inhibitors such as venlafaxine or citalopram may be introduced. Other agents from different pharmacological groups, such as clonidine, gabapentin, or pregabalin, have also proved to be effective in treating hot flushes. The efficacy of phytoestrogens has not been proven in randomized clinical trials. The importance of the placebo effect in decreasing vasomotor symptoms has also been reported in many research papers. Educating breast cancer patients in lifestyle changes which decrease the frequency and intensity of vasomotor symptoms can offer significant help too. This paper reviews the current state of research in order to assess the options for the treatment of hot flushes in breast cancer survivors.

Are Medications Involved in Vision and intracranial Pressure Changes Seen in Spaceflight?

NASA Technical Reports Server (NTRS)

Wotring, V. E.

2016-01-01

Some crewmembers have experienced changes in their vision after long-duration spaceflight on the ISS. These impairments include visual performance decrements, development of cotton-wool spots or choroidal folds, optic-disc edema, optic nerve sheath distention, and/or posterior globe flattening with varying degrees of severity and permanence. These changes are now used to define the visual impairment/intracranial pressure (VIIP) syndrome. The reasons for these potentially debilitating medical issues are currently unknown. The potential role of administered medications has not yet been examined, but it is known that many medications can have side effects that are similar to VIIP symptoms. Some medications raise blood pressure, which can affect intracranial pressure. Many medications that act in the central nervous system can affect intracranial pressures and/or vision. About 40% of the medications in the ISS kit are known to cause side effects involving changes in blood pressure, intracranial pressure and/or vision. For this reason, we proposed an investigation of the potential relationship between ISS medications and their risk of causing or exacerbating VIIP-like symptoms. The purpose of this study was to use medication usage records for affected and unaffected crew to determine if use of particular medications seemed to correlate with VIIP occurrence or severity.

Single dose epidural morphine instead of patient-controlled epidural analgesia in the second day of cesarean section; an easy method for the pain relief of a new mother.

Pain management has a particular importance after Cesarean section. This study was undertaken in order to document the efficacy and side-effects of epidural morphine instead of patient-controlled analgesia technique used for the control of post-cesarean pain during postoperative 24-48 hours. This study was performed as a retrospective review of patient charts who had received combined spinal-epidural anaesthesia. Post-cesarean analgesia was performed with epidural technique either by using (Group 1) patient-controlled epidural analgesia for 48 hours, or (Group 2) patient-controlled epidural analgesia for the first 24 hours and then single dose of 3 mg epidural morphine for the second 24 hours. Incidences of side-effects were similar in both groups. None of the patients experienced respiratory depression. Additional analgesia was used on an as-required basis in nine of 39 (23%) patients in Group 1 and six of 39 (13%) in Group 2. Small doses of epidural morphine provides up to 24 hours of pain relief from a single injection and could obviate the need for an indwelling epidural catheter on the second day of postcesarean section, thus reducing the potential for catheter-related complications.

Studies on adolescents and adults show that romantic love (RL) is associated with favorable emotional states. However, data on these associations are scarce for adults. The aim of the present study was, therefore, to explore the associations between RL, symptoms of depression, anxiety, hypomania (bright side and dark side), and sleep in a sample of adults. A total of 844 participants currently in love (M = 24.79 years, 75.8% females) took part in the study. They completed a series of questionnaires related to RL, symptoms of depression, anxiety, hypomania (bright side and dark side), and sleep. An increased state of RL was associated both with the bright and the dark side of hypomania (BRHYP and DAHYP). Relative to participants with BRHYP, participants with DAHYP reported stronger symptoms of depression and state anxiety, and poor sleep quality. The pattern of results adds to our knowledge that in adults RL is not entirely a joyful and happy period of life. Rather, data suggest that for young adults in love, bright versus dark side of hypomania was associated with a different quality of psychological functioning and sleep. We conclude that experiencing RL might be a critical life event associated with symptoms of depression and anxiety, and poor sleep.

Beta-blockade after myocardial infarction: practical implications of major clinical trials.

PubMed

Rehnqvist, N; Olsson, G

1987-01-01

A survey of the literature concerning 20 years' experience of beta-blockade after myocardial infarction indicates that several positive effects are achieved and that these are neither marginal nor transient. Mortality is reduced during the first year from about 10 to 7%. This has been shown for the individual beta-blockers metoprolol, propranolol, and timolol, and also when the data on all beta-blocker trials have been pooled. The effect is further enhanced if therapy continues. Patients at high risk of mortality can be separated fairly accurately from those at low risk. Thus, prophylactic treatment with the sole purpose of reducing mortality can be individualized. Effects on reinfarction are also already present after 1 year and are enhanced during further follow-up. It has not yet been possible, however, to identify those patients in whom this end-point will not be influenced. Furthermore, during extended follow-up, the proportion of asymptomatic patients who are free of side effects increases during treatment with beta-blockade, whereas it decreases during placebo therapy, due mostly to increased numbers of patients suffering from complications such as reinfarction, angina pectoris, cerebrovascular incidents, arrhythmias, or disturbances in the peripheral circulation. Twenty percent of patients experienced improved fitness when beta-blockade treatment was withdrawn, which balances the beneficial effects. No other drugs have been shown to have comparable beneficial effects. We conclude that the practical implications of the clinical trials indicate that beta-blockade should be continued for at least 3 years after myocardial infarction in patients without severe side effects.

Bilateral hemifacial spasm (HFS) is very rare. The literature contains only 32 clinical reports. Although microvascular decompression (MVD) is widely accepted as effective therapy for HFS, the etiology and surgical treatment of bilateral HFS are seldom addressed. We report our experience with MVD for patients with bilateral HFS. This retrospective report included 10 patients with bilateral HFS. All patients underwent MVD 1 or 2 times and were followed for 5-92 months. The clinical data were retrospectively analyzed. The etiology and treatment strategies were discussed. Spasm stopped completely on the operative side in all 10 patients. Symptoms on the other side also resolved in 3 patients, improved in 1 patient, and did not improve at all in 6 patients. Of the 6 patients with no improvement, 5 underwent another MVD on the contralateral side within 1 year and experienced relief of symptoms, and 1 patient refused the surgery. The neurovascular conflict was found in all the operations. During the follow-up period, no complications of hearing loss or facial palsy and no recurrence were observed. Vascular compression was the cause of bilateral HFS in our patients, and MVD relieved the symptoms. Thus, we recommend MVD for patients with bilateral HFS. A crowded cerebellopontine angle space and easy attrition of the neurovascular interfaces may play important roles in the occurrence of bilateral HFS. For some patients, 1 MVD can resolve bilateral symptoms. Copyright © 2016 Elsevier Inc. All rights reserved.

Long-range dynamic effects of point mutations propagate through side chains in the serine protease inhibitor eglin c.

PubMed

Clarkson, Michael W; Lee, Andrew L

2004-10-05

Long-range interactions are fundamental to protein behaviors such as cooperativity and allostery. In an attempt to understand the role protein flexibility plays in such interactions, the distribution of local fluctuations in a globular protein was monitored in response to localized, nonelectrostatic perturbations. Two valine-to-alanine mutations were introduced into the small serine protease inhibitor eglin c, and the (15)N and (2)H NMR spin relaxation properties of these variants were analyzed in terms of the Lipari-Szabo dynamics formalism and compared to those of the wild type. Significant changes in picosecond to nanosecond dynamics were observed in side chains located as much as 13 A from the point of mutation. Additionally, those residues experiencing altered dynamics appear to form contiguous surfaces within the protein. In the case of V54A, the large-to-small mutation results in a rigidification of connected residues, even though this mutation decreases the global stability. These findings suggest that dynamic perturbations arising from single mutations may propagate away from the perturbed site through networks of interacting side chains. That this is observed in eglin c, a classically nonallosteric protein, suggests that such behavior will be observed in many, if not all, globular proteins. Differences in behavior between the two mutants suggest that dynamic responses will be context-dependent.

The relation between driving experience and recognition of road signs relative to their locations.

Examine how driving experience and expectations affect the ability of experienced drivers to identify traffic signs--specifically, no right turn (NRT) and no left turn (NLT) at intersections. Failure to heed signs is a frequent cause of accidents, and the authors focused on the contributions of experience and expectancy to sign identification. Inexperienced and experienced drivers were connected to an eye tracker system and briefly exposed to various traffic scenes. Some of the pictures included an NRT sign at the expected location (on the right), and some included the same sign at an unexpected location (on the left). The same procedure was used with an NLT traffic sign. Experienced drivers identified traffic signs better than inexperienced drivers did when the signs were posted at the expected location but identified them worse than did inexperienced drivers when they were at unexpected locations. With experience, drivers' expectations regarding the expected location of traffic signs become so strong that violating these expectancies results in more identification errors among experienced drivers than among inexperienced drivers. To optimize experienced drivers' traffic sign identification, signs must be located in accordance with drivers' expectations--specifically, on the right side of the road. When signs are misplaced, crashes can be caused by inappropriate placement rather than inappropriate driving. Highway designers should ensure that their design conforms to standards that shape experienced drivers' expectations.

Bullous pemphigoid (BP) is the most common autoimmune blistering disease in older people, and is associated with significant morbidity and mortality. Oral corticosteroids are usually effective but the side-effects are thought to contribute to the high morbidity and mortality rate. Treatment with oral tetracyclines may be effective but high-quality, randomized controlled trials (RCTs) are needed to confirm this. To compare the effectiveness and safety of two strategies for treating BP. This is a two-arm, parallel group, 52-week RCT comparing doxycycline with prednisolone for initial treatment of BP. Dose is fixed for the initial 6 weeks of treatment (doxycycline 200 mg daily; prednisolone 0.5 mg kg(-1) daily), after which it can be adjusted according to need. A total of 256 patients with BP will be recruited in the U.K. and Germany. The primary outcomes are: (i) effectiveness (assessor-blinded blister count at 6 weeks) and (ii) safety [proportion of patients experiencing ≥ grade 3 adverse events (i.e. severe, life: threatening or fatal) related to trial medication during the year of follow-up]. Primary effectiveness analysis will be an assessment of whether doxycycline can be considered noninferior to prednisolone after 6 weeks of treatment. Primary safety analysis is a superiority analysis at 12 months. Secondary outcomes include longer-term assessment of effectiveness, relapse rates, the proportion of patients experiencing any grade of adverse events related to treatment, quality of life and cost-effectiveness. The trial will provide good evidence for whether the strategy of starting BP treatment with doxycycline is a useful alternative to prednisolone. © 2015 British Association of Dermatologists.

Patients have to discontinue the use of oral iron therapy due to the development of side effects and lack of long-term adherence to medication for iron deficiency anemia. This study aimed to evaluate the therapeutic effectiveness, safety, and cost of intravenous iron sucrose therapy. The computerized database and medical records of 453 patients diagnosed with iron deficiency anemia who received intravenous iron sucrose therapy for iron deficiency anemia between 2004 and 2008 were reviewed. The improvement of hematologic parameters and cost of therapy were evaluated 4 weeks after therapy. 453 patients (443 females, 10 males; age: 44.2 +/- 12.3 years) received iron sucrose therapy. Mean hemoglobin, hematocrit, and mean corpuscular volume values were 8.2 +/- 1.4 g/dL, 26.9 +/- 3.8%, and 66.1 +/- 7.8 fL, respectively, before therapy and 11.5 +/- 1.0 g/dL, 35.8 +/- 2.5%, 76.5 +/- 6.1 fL, respectively, after therapy (P < 0.001). A mean ferritin level of 3.4 +/- 2.4 ng/mL before therapy increased to 65.9 +/- 40.6 ng/mL after therapy (P < 0.001). All patients responded to intravenous iron therapy (transferrin saturation values of the patients were >50%). The mean cost of therapy was 143.07 +/- 29.13 US dollars. The therapy was well tolerated. Although the cost of intravenous iron sucrose therapy may seem high, a lack of adherence to therapy and side effects including gastrointestinal irritation during oral iron therapy were not experienced during intravenous therapy.

Pirfenidone is an antifibrotic compound able to slow down disease progression in patients with idiopathic pulmonary fibrosis (IPF). To investigate the safety and efficacy of pirfenidone in patients with IPF in a real-life setting. This was a multicenter, retrospective, real-life, observational study for patients with IPF receiving pirfenidone. We identified 92 patients with IPF receiving pirfenidone. Eighty patients (70 males and 10 females, mean age ± SD: 68.1 + 7.5, mean %FVC ± SD = 74.9 ± 17.2, mean %DL CO  ± SD = 48.1 ± 16.9) were included in the analysis. Skin-related (25%) and gastrointestinal (17.5%) adverse events were the most common and led to drug discontinuation in 22.5% of cases. The majority (87%) of patients experienced side effects during the first 6 months of treatment. At 36 months, changes in %FVC and %DL CO were -9.25 ± 16.34 and -9.26 ± 15.26, respectively. At 6, 12, and 24 months after treatment initiation ( n  = 80, 60, and 26), 18, 15, and 5 patients (22.5, 25, and 19.2%) experienced significant (>10%) and 11, 3, and 3 patients (13.8, 5, and 11.5%) experienced marginal (5-10%) %FVC improvement; and 13, 6, and 1 patient (16.2, 10, and 3.9%) experienced marginal (-5 to -10%) and 20, 21, and 8 patients (25, 35, and 30.8%) experienced significant decline (<-10%) in %FVCpred. Median survival was 851 days, and 41 patients died during the study period. Pirfenidone demonstrated an acceptable safety and therapeutic profile in patients with IPF on a longitudinal basis. Prospective observational registries are urgently needed to provide a real-world view of outcomes of pirfenidone in clinical practice.

Pulsed dye laser (PDL) represents the gold-standard treatment for port wine stains (PWS). However, approximately 20% of patients are poor responders and yield unsatisfactory end-results. The Alexandrite (Alex) laser may be a therapeutic alternative for selected PWS subgroups, but optimal laser parameters are not known. The aim of this study was to assess clinical PWS clearance and safety of Alex laser at a range of pulse durations. Sixteen individuals (14 previously PDL-treated) with deep red (n = 4), purple macular (n = 5) and purple hypertrophic (n = 7) PWS were included. Four side-by-side test areas were marked within each lesion. Three test areas were randomized to Alex laser at pulse durations of 3, 5, or 10 ms (8 mm spot, DCD 60/40), while the fourth was untreated. The lowest effective fluence to create purpura within the entire test spot was titrated and applied to intervention areas. Standardized clinical photographs were taken prior to, immediately after laser exposure and at 6-8 weeks follow up. Clinical PWS clearance and laser-related side effects were assessed using clinical photos. Alex laser at 3, 5, and 10 ms pulse durations demonstrated significant clearance compared to untreated controls (P < 0.001). Three milli second pulse duration exhibited improved clearance versus 5 ms (P = 0.016) and 10 ms (P = 0.004), while no difference between five and 10 ms was shown (P = 0.063). Though not significant, good responders (>50% clearance) were more likely to have purple hypertrophic PWS (5/7) compared to purple macular (2/5) and deep red lesions (1/4). Eight laser-exposed test areas (17%) developed hypopigmented atrophic scarring. Side effects tended to be more frequently observed with 5 ms (n = 4) and 10 ms (n = 3) versus 3 ms pulse duration (n = 1). Correspondingly, 3 ms was associated with a superior (n = 6) or comparable (n = 10) overall cosmetic appearance for all individuals. Alex laser at 3 ms pulse duration offers superior clinical clearance and safety compared to 5 and 10 ms, and seems best suited for purple hypertrophic PWS. Treatment should be restricted to experienced personnel due to a particularly narrow therapeutic window. Lasers Surg.

This report describes a patient case utilizing a nontraditional sedative, continuous infusion ketamine, as an alternative agent for intensive care unit (ICU) sedation. A 27-year-old female presented for neurosurgical management of a coup contrecoup injury, left temporal fracture, epidural hemorrhage (EDH), and temporal contusion leading to sustained mechanical ventilation. The patient experienced profound agitation during mechanical ventilation and developed adverse effects with all traditional sedatives: benzodiazepines, dexmedetomidine, opioids, and propofol. Ketamine was titrated to effect and eliminated the need for other agents. This led to successful ventilator weaning, extubation, and transition of care. Given the unique side effect profile of ketamine, it is imperative that information is disseminated on potential utilization of this agent. More information is needed regarding dosing, monitoring, and long-term effects of utilizing ketamine as a continuous ICU sedative, but given the analgesia, anesthesia, and cardiopulmonary stability, future utilization of this medication for this indication seems promising.

Severe recurrent acute attacks of porphyria have traditionally been treated with either prophylactic human haemin or gonadorelin analogues (GnA) in females. Evidence on the most effective treatment for this patient subgroup is lacking. This audit surveyed the use of prophylactic GnA in the UK.Twenty female patients (who experienced between 2 and 45 acute attacks of porphyria requiring hospitalisation and treatment with human haemin prior to GnA prophylaxis) were included in the audit. Data was retrospectively collected based on patient history and case review.Twenty three treatment courses were given lasting a median period of 12 months. Monthly subcutaneous Goserelin was most commonly used. In three patients in whom timing with the menstrual cycle was not considered, an acute attack occurred after initiation of the first dose. The majority of patients experienced oestrogen deficiency symptoms during treatment. Fifty percent of the prescribed courses of GnA resulted in a degree of clinical benefit. This successfully treated group experienced between 3 and 20 acute attacks prior to and between 0 and 6 acute attacks during GnA treatment.The audit revealed large variation in practice in the United Kingdom regarding indication, duration of treatment, specific drug used and management of side effects. In view of the limited treatment options available for this cohort and the mixed outcome successes reported, we believe it is reasonable for porphyria specialists to continue offering GnA treatment to women with severe recurrent debilitating acute attacks of porphyria associated with the menstrual cycle, and we propose best practice guidelines to standardise management.

Arc fault detection system

Jha, Kamal N.

1999-01-01

An arc fault detection system for use on ungrounded or high-resistance-grounded power distribution systems is provided which can be retrofitted outside electrical switchboard circuits having limited space constraints. The system includes a differential current relay that senses a current differential between current flowing from secondary windings located in a current transformer coupled to a power supply side of a switchboard, and a total current induced in secondary windings coupled to a load side of the switchboard. When such a current differential is experienced, a current travels through a operating coil of the differential current relay, which in turn opens an upstream circuit breaker located between the switchboard and a power supply to remove the supply of power to the switchboard.

Motor vehicle crashes are the leading cause of death among young drivers. Though previous research has focused on crash events, near crashes offer additional data to help identify driver errors that could potentially lead to crashes as well as evasive maneuvers used to avoid them. The Strategic Highway Research Program 2 (SHRP2) Naturalistic Driving Study (NDS) contains extensive data on real-world driving and offers a reliable methodology to quantify and study near crashes. This article presents findings on near crashes and how they compare to crash events among teen, young adult, and experienced adult drivers. A subset from the SHRP2 database consisting of 1,653 near crashes for teen (16-19 years, n = 550), young adult (20-24 years, n = 748), and experienced adult (35-54 years, n = 591) drivers was used. Onboard instrumentation including scene cameras, accelerometers, and Global Positioning System logged time series data at 10 Hz. Scene videos were reviewed for all events to classify near crashes based on 7 types: rear-end, road departure, intersection, head-on, side-swipe, pedestrian/cyclist, and animal. Near crash rates, incident type, secondary tasks, and evasive maneuvers were compared across age groups and between crashes and near crashes. For rear-end near crashes, vehicle dynamic variables including near crash severity, headway distance, time headway, and time to collision at the time of braking were compared across age groups. Crashes and near crashes were combined to compare the frequency of critical events across age. Teen drivers exhibited a significantly higher (P <.01) near crash rate than young adult and experienced adult drivers. The near crash rates were 81.6, 56.6, and 37.3 near crashes per million miles for teens, young adults, and experienced adults, respectively. Teens were also involved in significantly more rear-end (P <.01), road departure (P <.01), side-swipe (P <.01), and animal (P <.05) near crashes compared to young and experienced adults. Teens exhibited a significantly greater (P <.01) critical event rate of 102.2 critical events per million miles compared to 72.4 and 40.0 critical events per million miles for young adults and experienced adults, respectively; the critical event rate ratio was 2.6 and 1.8 for teens and young adults, respectively. To our knowledge, this is the first study to examine near crashes among teen, young adult, and experienced adult drivers using SHRP2 naturalistic data. Near crash and critical event rates significantly decreased with increasing age and driver experience. Overall, teens were more than twice as likely to be involved in critical events compared to experienced adults. These data can be used to develop more targeted driver training programs and help manufacturers design active safety systems based on the most common driving errors for vulnerable road users.

Juvenile anadromous salmonid production in upper Columbia River side channels with different levels of hydrological connection

Martens, Kyle D.; Connolly, Patrick J.

2014-01-01

We examined the contribution of three types of side channels based on their hydrologic connectivity (seasonally disconnected, partially connected, and connected) to production of juvenile anadromous salmonids. Juvenile steelhead Oncorhynchus mykiss and Chinook Salmon O. tshawytscha were found in all three of these side channel types and in each year of the study. Upon connection with the main stem at high flows, the seasonally disconnected side channels experienced an emptying out of the previous year's fish while filling with young-of-year fish during the 2- to 4-month period of hydrologic connection. There were no differences between the densities of juvenile steelhead and Chinook Salmon and the rate of smolts produced among the three types of side channels. Recently reintroduced Coho Salmon O. kisutch had sporadic presence and abundance in partially and connected side channels, but the smolt production rate was over two times that of steelhead and Chinook Salmon in seasonally disconnected side channels. Within seasonally disconnected side channels, young-of-year salmonids in deep pools (≥100 cm) had greater survival than those in shallow pools (<100 cm). Densities of juvenile steelhead in all side channel types were similar to those in tributaries and were higher than in main-stem lateral margins. Juvenile Chinook Salmon densities were higher in side channels than in both tributary and main-stem lateral margins. Our results suggest that improving quality of pool habitat within seasonally disconnected side channels can result in improved survival for juvenile anadromous salmonids during the period of disconnection. Habitat improvement in these seasonally disconnected side channels should be recognized as a worthy restoration strategy, especially when full connectivity of side channels may not be a feasible target (e.g., through lack of water availability) or when full connectivity may present too high a risk (e.g., flooding, stream capture, bank destabilization).

The most frequent injuries in badminton players are in the lower extremities, especially in the Achilles tendon. The game of badminton may be related to abnormal intratendinous flow in the Achilles tendon as detected by color Doppler ultrasound. To a certain extent, this blood flow might be physiological, especially when examined after match. Cohort study (prevalence); Level of evidence, 3. Seventy-two elite badminton players were interviewed regarding Achilles tendon pain (achillodynia) in the preceding 3 years. Color Doppler was used to examine the tendons of 64 players before their matches and 46 players after their matches. Intratendinous color Doppler flow was graded from 0 to 4. The Achilles tendon was divided into dominant (eg, right side for right-handed players and vice versa) and nondominant side and classified as midtendon, preinsertional, and calcaneal areas. Of 72 players, 26 had experienced achillodynia in 34 tendons, 18 on the dominant side and 16 on the nondominant side. In 62% of the players with achillodynia, the problems had begun slowly, and the median duration of symptoms was 4 months (range, 0-36 months). Thirty-five percent had ongoing pain in their tendons for a median duration of 12 months (range, 0-12 months). Achillodynia was not associated with the self-reported training load or with sex, age, weight, singles or doubles players, or racket side. Forty-six players were scanned before and after match. At baseline, color Doppler flow was present in the majority of players, and only 7 (16%) players had no color Doppler flow in either tendon. After match, all players had some color Doppler flow in 1 or both tendons. Achillodynia and color Doppler flow were related in the nondominant Achilles tendon (chi-square, P = .008). The grades of Doppler flow also increased significantly after match in the preinsertional area in both the nondominant (P = .0002) and dominant (P = .005) side tendons. A large proportion of the players had experienced achillodynia and habitually played with a degree of pain that demanded medication. The self-reported pain was associated with increased intratendinous color Doppler flow in the nondominant Achilles tendon. Doppler flow was found in most players before and in all players after the match and therefore may in part be a physiological response to activity.

Myasthenia gravis tends to affect children in China. Oral pyridostigmine and prednisone could effectively improve the symptoms, but multiple side effects become a major concern after long-term oral prednisone. To avoid the long-term complications of prednisone therapy and to obtain more satisfactory improvement, we tested the efficacy and safety of tacrolimus in children with myasthenia gravis. Children with myasthenia gravis who had not achieved satisfactory improvement or who experienced severe side effects after prednisone therapy were recruited between January 2015 and December 2016 at Tongji Hospital. All the children were treated with tacrolimus 1 mg to 2 mg daily and the dose was adjusted on the basis of the clinical response and the serum concentration. The dosage of prednisone, the severity of symptoms, blood samples, the serum concentration of tacrolimus, and titers of antiacetylcholine receptor antibodies were evaluated every four weeks. Fourteen children were enrolled. One child withdrew two weeks after the enrollment. Thirteen children have completed the therapy for one year. At the end point, the dosage of prednisone was significantly decreased (P < 0.05), the symptoms were evaluated by the quantitative myasthenia gravis score, and myasthenia gravis-specific manual muscle testing and myasthenia gravis-activities of daily living scores were significantly improved (P < 0.05, P < 0.05, and P < 0.01, respectively). More importantly, ten (76.9%) patients had completely discontinued prednisone, and the major side effects were nearly reversed. The mean titer of antiacetylcholine receptor antibodies significantly dropped from 1.96±2.62 nmol/L to 0.70±1.04 nmol/L (P < 0.05). No severe adverse events were reported. Our results suggest that tacrolimus is a promising agent for children with refractory myasthenia gravis. Randomized clinical trials are needed to confirm the observation.

ABSTRACT Purpose Two new drugs with mucin-inducing and secretion-promotive effects, rebamipide and diquafosol, were recently approved as topical dry-eye treatments. We report two cases in which the long-term use of mucin-inducing eye drops improved chronic ocular graft-versus-host disease (cGVHD)–related dry eye and ocular cicatricial pemphigoid (OCP)-like disease. Case Reports Case 1. A 61-year-old woman had cGVHD-related dry eye that resisted traditional medications. Next, we use topical diquafosol in addition to conventional treatments. The patient used diquafosol for 6 months without experiencing any side effects. The symptoms, including dry-eye sensation, ocular pain, foreign body sensation, and photophobia, as well as ocular surface findings including fluorescein and rose bengal scores and tear break-up time (TBUT), partly improved. To further improve the clinical signs and symptoms and decrease chronic inflammation, rebamipide was added to diquafosol. The symptoms, TBUT, and fluorescein and rose bengal scores markedly improved after long-term dual treatment without any side effects for 6 months. Case 2. A 77-year-old woman had OCP-like disease with dry eye. The patient did not improve using the currently available conventional treatments. Next, we use topical rebamipide in addition to conventional treatments. Symptoms including asthenopia, dry-eye sensation, ocular pain, and dull sensation, as well as fluorescein and rose bengal scores and TBUT, partly improved. Specifically, functional visual acuity was markedly improved after commencement of rebamipide. To further improve the clinical signs and symptoms and increase tear film stability and tear film volume, diquafosol was added to rebamipide. The combination of diquafosol and rebamipide worked for the patient. Improvements were seen in several symptoms, fluorescein and rose bengal scores, Schirmer test value, and TBUT without any side effects for 12 months. Conclusions Long-term treatment with topical rebamipide and diquafosol can improve dry eye in patients with cGVHD or OCP-like disease. PMID:25785527

Microbubble-mediated ultrasound therapy: a review of its potential in cancer treatment

Ibsen, Stuart; Schutt, Carolyn E; Esener, Sadik

The inherently toxic nature of chemotherapy drugs is essential for them to kill cancer cells but is also the source of the detrimental side effects experienced by patients. One strategy to reduce these side effects is to limit the healthy tissue exposure by encapsulating the drugs in a vehicle that demonstrates a very low leak rate in circulation while simultaneously having the potential for rapid release once inside the tumor. Designing a vehicle with these two opposing properties is the major challenge in the field of drug delivery. A triggering event is required to change the vehicle from its stable circulating state to its unstable release state. A unique mechanical actuation type trigger is possible by harnessing the size changes that occur when microbubbles interact with ultrasound. These mechanical actuations can burst liposomes and cell membranes alike allowing for rapid drug release and facilitating delivery into nearby cells. The tight focusing ability of the ultrasound to just a few cubic millimeters allows for precise control over the tissue location where the microbubbles destabilize the vehicles. This allows the ultrasound to highlight the tumor tissue and cause rapid drug release from any carrier present. Different vehicle designs have been demonstrated from carrying drug on just the surface of the microbubble itself to encapsulating the microbubble along with the drug within a liposome. In the future, nanoparticles may extend the circulation half-life of these ultrasound triggerable drug-delivery vehicles by acting as nucleation sites of ultrasound-induced mechanical actuation. In addition to the drug delivery capability, the microbubble size changes can also be used to create imaging contrast agents that could allow the internal chemical environment of a tumor to be studied to help improve the diagnosis and detection of cancer. The ability to attain truly tumor-specific release from circulating drug-delivery vehicles is an exciting future prospect to reduce chemotherapy side effects while increasing drug effectiveness.

Background Pain from episiotomy or tearing of perineal tissues during childbirth is often poorly treated and may be severe. This randomized double-blind controlled trial was performed to compare the effectiveness, side effects and cost of, and patient preference for, 2 analgesics for the management of postpartum perineal pain. Methods A total of 237 women who gave birth vaginally with episiotomy or a third- or fourth-degree tear between August 1995 and November 1996 at a tertiary-level teaching and referral centre for obstetric care in Vancouver were randomly assigned to receive either ibuprofen (400 mg) (n = 127) or acetaminophen (600 mg) with codeine (60 mg) and caffeine (15 mg) (Tylenol No. 3) (n = 110), both given orally every 4 hours as necessary. Pain ratings were recorded before the first dose and at 1, 2, 3, 4, 12 and 24 hours after the first dose on a 10-cm visual analogue scale. Side effects and overall opinion were assessed at 24 hours. Results Ibuprofen and acetaminophen with codeine had similar analgesic properties in the first 24 hours post partum (mean pain rating 3.4 and 3.3, mean number of doses in 24 hours 3.4 and 3.3, and proportion of treatment failures 13.8% [16/116] and 16.0% [16/100] respectively). Significantly fewer subjects in the ibuprofen group than in the acetaminophen with codeine group experienced side effects (52.4% v. 71.7%) (p = 0.006). There were no significant differences in overall patient satisfaction between the 2 groups. The major determinant of pain intensity was forceps-assisted delivery. Overall, 78% of the treatment failures were in women with forceps-assisted deliveries. Interpretation Since the 2 analgesics were rated similarly, ibuprofen may be the preferred choice because it is less expensive and requires less nursing time to dispense. Further studies need to address improved analgesia for women with forceps-assisted deliveries. PMID:11706909

[Purpose] The purpose of this study was to assess the effects of flexi-bar exercises and non-flexi-bar exercises on trunk muscle activity in different postures in healthy adults. [Subjects] Twenty healthy right-hand dominant adults (10 males and 10 females) were selected for this study. None of the participants had experienced any orthopedic problems in the spine or in the upper and lower extremities in the previous six months. [Methods] The subjects were instructed to adopt three exercise postures: posture 1, quadruped; posture 2, side-bridge; and posture 3, standing. Surface electromyography of selected trunk muscles was normalized to maximum voluntary isometric contraction. [Results] The external oblique, internal oblique, and erector spinae muscle activity showed significant differences between flexi-bar exercises and non-flexi-bar exercises. [Conclusion] The results of this study suggest that flexi-bar exercises are useful in the activation of trunk muscles.

Treatment of a mild chronic case of ciguatera fish poisoning with intravenous mannitol, a case study.

PubMed

Mitchell, Gary

2005-03-01

This article describes a recent case of ciguatera poisoning treated with intravenous mannitol. Mannitol has been used with good effect in non-controlled studies in acutely severely poisoned patients, but is not described in the treatment of chronic or milder poisoning. Our patient was a 35-year-old Niuean man who had eaten a ciguatoxic fish two weeks previously. His symptoms were not severe but were very unpleasant and restricted his ability to work. He was given a single dose of mannitol (0.66g/kg) as an intravenous infusion over two hours. His symptoms dramatically improved within 24 hours, and within a few days he felt virtually back to his former self. He experienced no side effects to the mannitol. It is suggested that intravenous mannitol may prove to be a useful treatment for mild to moderate ciguatera poisoning, and for patients who present late for treatment.

Developing countries are experiencing an epidemic of chronic non-communicable chronic diseases with high socio-economic costs. Studies of traditional foods with beneficial health properties could contribute to diminish these problems. Legumes rich in proteins like Lupinus mutabilis decreases blood glucose and improves insulin sensitivity in animals and humans. We report the results of a phase II clinical trial conducted to assess the role of cooked L. mutabilis and its purified alkaloids on blood glucose and insulin in volunteers with diabetes. Results indicate that consumption of cooked L. mutabilis or its purified alkaloids decreased blood glucose and insulin levels. The decreases in serum glucose concentrations from base line to 90 minutes were statistically significant within both treatment groups; however, there were not differences between groups. Serum insulin levels were also decreased in both groups however the differences were not statistically significant. None of the volunteers in either group presented side effects.

The most important adverse effects of phenobarbital, an anticonvulsant drug, are behavior and cognitive alterations. Hypersensitivity syndrome caused by phenobarbital presenting with a leukemoid reaction is a rare side effect, which is rarely ever reported and needs to be known. We report on a 27-year-old Chinese woman who experienced hypersensitivity syndrome three weeks after the initiation of phenobarbital. The patient developed fever, skin rash, face swelling, lymphadenopathy, myalgia, hepatitis, eosinophilia, atypical lymphocytes and leukocytosis. Along with the pathological progress of the disease, the patient noticed a gradual exacerbation of her symptoms. And the highest leukocyte count was up to 127.2 x 10(9)/L. After discontinuing of phenobarbital and administration of methylprednisolone combined with the intravenous immunoglobulin shock therapy, all initial symptoms improved and the leukocyte count normalized. This case is reported because of its rarity of the leukemoid reaction secondary to hypersensitivity syndrome to phenobarbital.

Varenicline may trigger severe hypoglycaemia in Type 1 diabetes.

Varenicline is a new drug indicated for smoking cessation. It has primarily been investigated in healthy adults. The commonest side-effects are nausea, headache, sleep disturbance, constipation, flatulence and vomiting. Hypoglycaemia has not been reported. As smoking cessation is important to reduce risk of cardiovascular morbidity, especially in diabetes, use of effective drugs indicated for smoking cessation is rational. We report multiple episodes of severe hypoglycaemia after starting varenicline in a 53-year-old woman with Type 1 diabetes. Since onset of diabetes at age 25 years and until start of varenicline therapy, she had only experienced one episode of severe hypoglycaemia and hypoglycaemia awareness was not impaired. The severe hypoglycaemic episodes disappeared after withdrawal of varenicline. We recommend cautious prescription of varenicline, intensified blood glucose monitoring and careful education of patients with diabetes treated with varenicline. Further investigation of the use of varenicline in patients with diabetes is warranted.

The use of lisuride in the treatment of multiple system atrophy with autonomic failure (Shy-Drager syndrome).

In a controlled trial lisuride, an ergolene derivative with dopamine receptor agonist properties was given maximum tolerated doses (2.4 mg/day) to seven patients with multiple system atrophy with autonomic failure (Shy-Drager syndrome). Improvement in Parkinsonian features occurred in only one patient and another patient who had been deriving marked benefit from levodopa treatment before the study began failed to respond to large doses of lisuride. Psychiatric side effects (including nightmares, isolated visual hallucinations and toxic confusional states) were the dose-limiting factor in six patients. A modest reduction in orthostatic hypotension occurred in two patients, one of whom had experienced an aggravation of this disturbance on levodopa and bromocriptine. Destruction of post-synaptic dopamine receptors and damage to central noradrenergic systems may offer an explanation for the lack of therapeutic effect of lisuride. PMID:7241162

No blank slates: Pre-existing schemas about pharmaceuticals predict memory for side effects.

PubMed

Heller, Monika K; Chapman, Sarah C E; Horne, Rob

2017-04-01

Attribution of symptoms as medication side effects is informed by pre-existing beliefs about medicines and perceptions of personal sensitivity to their effects (pharmaceutical schemas). We tested whether (1) pharmaceutical schemas were associated with memory (recall/recognition) for side effect information (2) memory explained the attribution of a common unrelated symptom as a side effect. In this analogue study participants saw the patient leaflet of a fictitious asthma drug listing eight side effects. We measured recall and recognition memory for side effects and used a vignette to test whether participants attributed an unlisted common symptom (headache) as a side effect. Participants who perceived pharmaceuticals as more harmful in general recalled fewer side effects correctly (r Correct Recall  = -.273), were less able to differentiate between listed and unlisted side effects (r Recognition Sensitivity  = -.256) and were more likely to attribute the unlisted headache symptom as a side effect (r side effect attribution  = .381, ps < .01). The effect of harm beliefs on side effect attribution was partially mediated by correct recall of side effects. Pharmaceutical schemas are associated with memory for side effect information. Memory may explain part of the association between pharmaceutical schemas and the attribution of unrelated symptoms as side effects.

Portal hypertension is a common and potentially devastating condition in children. Notwithstanding advances in the nonsurgical management of portal hypertension, surgery remains an important treatment modality in select patients. We report here on our experience in the past 12 years. To describe the profile of, indication for, and complications of shunt surgery in children with portal hypertension. Twelve children underwent shunt surgery between 2005 and 2017. Patient records were reviewed. Fourteen procedures were performed on 12 patients during the study period. The median age at surgery was 6.5 (range 1 - 18) years. Six patients were male. Gastrointestinal bleeding that was not amenable to endoscopic control was the most common indication for surgery. Portal vein thrombosis was the most common cause of portal hypertension in our series (n=11). Two-thirds (8/12) of all patients had an identifiable underlying risk factor for portal vein thrombosis. One-third of all patients (4/12) underwent a meso-portal bypass procedure (Rex shunt), while 58% (7/12) were managed with a distal splenorenal shunt. All patients received postoperative thromboprophylaxis. We experienced a single mortality, 1 patient experienced shunt thrombosis that required revision shunt surgery, and 2 patients experienced anastomotic strictures, with one being managed with revision surgery and the other currently awaiting radiological venoplasty. Surgery is a safe and important tool in the management of children with non-cirrhotic portal hypertension and those with sufficient hepatic reserve who fail to respond to more conservative methods for the treatment of side effects of portal hypertension.

the possible diff erences in processing gustatory stimuli in healthy subjects was investigated by magnetoencephalography (meg). meg recordings were evaluated for 10 healthy volunteers (3 men within the age range 20-46 years, 7 women within the age range 10-28 years), with four diff erent gustatory stimuli: sweet, bi" er, sour and salty. Fast fourier transform was performed on meg epochs recorded for the above conditions and the eff ect of each kind of stimuli on alpha rhythm was examined. A significant higher percent of alpha power was found irrespective of hemispheric side in all gustatory states located mainly at the occipital, le$ and right parietal lobes. One female volunteer experienced no statistically signifi cance when comparing normal with salty and sour taste respectively. Two female volunteers exhibited no statistically signifi cance when comparing their normal with their salty taste. One male volunteer experienced no statistically signifi cance when comparing the normalbitter and normal-salty states correspondingly. All the other subjects showed statistically signifi cant changes in alpha power for the 4 gustatory stimuli. The pattern of activation caused by the four stimuli indicated elevated gustatory processing mechanisms. This cortical activation might have applicability in modulation of brain status.

The choice of contraceptive tools is not an easy thing because the risks or effects will give impact on the body that never using it previously. in the other side, there is no contraception always suit for everybody because the circumstances of each body is different, so the extensive knowledge must be needed to know the advantages and disadvantages of each contraceptive tools then adjusted to the user's body.The expert system for contraceptive tools uses Forward Chaining search method combined with Certainty Factors Method. These method value the patient's indication. The Expert system gives the output data which define the kind of tool uses of the patient. the results obtained will be able to help people to find indications that lead to appropriate contraceptive tools and advice or suggestions about these tools. The success rate of the contraceptive tools decision experienced by experienced by the user by using forward chaining combined with the CF computation method is also influenced by the number of indication criteria selected by the user. Based on testing that has been done, expert system contraception tools has accuracy level equal to 75%.

Visually induced plasticity of auditory spatial perception in macaques.

PubMed

Woods, Timothy M; Recanzone, Gregg H

2004-09-07

When experiencing spatially disparate visual and auditory stimuli, a common percept is that the sound originates from the location of the visual stimulus, an illusion known as the ventriloquism effect. This illusion can persist for tens of minutes, a phenomenon termed the ventriloquism aftereffect. The underlying neuronal mechanisms of this rapidly induced plasticity remain unclear; indeed, it remains untested whether similar multimodal interactions occur in other species. We therefore tested whether macaque monkeys experience the ventriloquism aftereffect similar to the way humans do. The ability of two monkeys to determine which side of the midline a sound was presented from was tested before and after a period of 20-60 min in which the monkeys experienced either spatially identical or spatially disparate auditory and visual stimuli. In agreement with human studies, the monkeys did experience a shift in their auditory spatial perception in the direction of the spatially disparate visual stimulus, and the aftereffect did not transfer across sounds that differed in frequency by two octaves. These results show that macaque monkeys experience the ventriloquism aftereffect similar to the way humans do in all tested respects, indicating that these multimodal interactions are a basic phenomenon of the central nervous system.

Contrast-enhanced ultrasound (CEUS) has been suggested as a new method to measure cerebral perfusion in patients with acute brain injury. In this systematic review, the tolerability, repeatability, reproducibility and accuracy of different CEUS techniques for the quantification of cerebral perfusion were assessed. We selected studies published between January 1994 and March 2017 using CEUS to measure cerebral perfusion. We included 43 studies (bolus kinetics n = 31, refill kinetics n = 6, depletion kinetics n = 6) with a total of 861 patients. Tolerability was reported in 28 studies describing 12 patients with mild and transient side effects. Repeatability was assessed in 3 studies, reproducibility in 2 studies and accuracy in 19 studies. Repeatability was high for experienced sonographers and significantly lower for less experienced sonographers. Reproducibility of CEUS was not clear. The sensitivity and specificity of CEUS for the detection of cerebral ischemia ranged from 75% to 96% and from 60% to 100%. Limited data on repeatability, reproducibility and accuracy may suggest that this technique could be feasible for use in acute brain injury patients.

2015-07-01

Many cancer survivors continue to experience ongoing symptoms, such as fatigue and cognitive impairment, which are poorly managed and have few effective, evidence-based treatment options. Neurofeedback is a noninvasive, drug-free form of brain training that may alleviate long-term symptoms reported by cancer patients. The purpose of this systematic review of the literature was to describe the effectiveness and safety of neurofeedback for managing fatigue and cognitive impairment. A systematic review of the literature was conducted using Joanna Briggs Institute (JBI) methodology. A comprehensive search of 5 databases was conducted: Medline, CINAHL, AMED, PsycInfo, and Embase. Randomized and nonrandomized controlled trials, controlled before and after studies, cohort, case control studies, and descriptive studies were included in this review. Twenty-seven relevant studies were included in the critical appraisals. The quality of most studies was poor to moderate based on the JBI critical appraisal checklists. Seventeen studies were deemed of sufficient quality to be included in the review: 10 experimental studies and 7 descriptive studies. Of these, only 2 were rated as high-quality studies and the remaining were rated as moderate quality. All 17 included studies reported positive results for at least one fatigue or cognitive outcome in a variety of populations, including 1 study with breast cancer survivors. Neurofeedback interventions were well tolerated with only 3 studies reporting any side effects. Despite issues with methodological quality, the overall positive findings and few reported side effects suggest neurofeedback could be helpful in alleviating fatigue and cognitive impairment. Currently, there is insufficient evidence that neurofeedback is an effective therapy for management of these symptoms in cancer survivors, however, these promising results support the need for further research with this patient population. More information about which neurofeedback technologies, approaches, and protocols could be successfully used with cancer survivors and with minimal side effects is needed. This research will have significance to nurses and physicians in oncology and primary care settings who provide follow-up care and counseling to cancer survivors experiencing debilitating symptoms in order to provide information and education related to evidence-based therapy options. © The Author(s) 2015.

The aim of this study consists of the application of an experimental protocol that allows information to be obtained about the visual search strategies elaborated by swimming coaches. 16 swimming coaches participated. The Experienced group (n=8) had 16.1 yr. (SD=8.2) of coaching experience and at least five years of experience in underwater vision. The Nonexperienced group in underwater vision (n= 8) had 4.2 yr. (SD= 4.0) of coaching experience. Participants were tested in a laboratory environment using a video-projected sample of the crawl stroke of an elite swimmer. This work discusses the main areas of the swimmer's body used by coaches to identify and analyse errors in technique from overhead and underwater perspectives. In front-underwater videos, body roll and mid-water were the locations of the display with higher percentages of fixation time. In the side-underwater slow videos, the upper body was the location with higher percentages of visual fixation time and was used to detect the low elbow fault. Side-overhead takes were not the best perspectives to pick up information directly about performance of the arms; coaches attended to the head as a reference for their visual search. The observation and technical analysis of the hands and arms were facilitated by an underwater perspective. Visual fixation on the elbow served as a reference to identify errors in the upper body. The side-underwater perspective may be an adequate way to identify correct knee angles in leg kicking and the alignment of a swimmer's body and leg actions.

Synechia and stenosis formation after endoscopic sinus surgery (ESS) represents a potential source of surgical failure. Mitomycin C (MMC) has been used successfully in other fields to decrease postoperative scar formation. We hypothesize that the topical application of MMC reduces the incidence of stenosis and synechia formation after ESS. This study is a randomized, controlled, single-blinded study based in a tertiary care teaching hospital. After routine ESS, a pledget soaked in MMC (0.5%) was randomly placed into the middle meatus of one nasal cavity for 5 minutes and a pledget soaked in saline was placed in the contralateral side in each patient. A blinded observer followed the patients for any evidence of stenosis or synechia formation. The medical records of enrolled patients were reviewed for demographics, diagnosis, prior surgery, type of sinus surgery, complications, incidence of stenosis/synechia, and need for further procedures. Twenty-nine patients were included in the final analysis. The mean follow-up period was 15 months (range, 3-32 months). There were no complications in this series. Eight patients experienced 10 episodes of synechia formation and one patient experienced 1 episode of synechia formation and 1 episode of stenosis of the maxillary sinus ostium. Seven of the 12 episodes of synechia/stenosis occurred on the side of the MMC application and the remaining 5 episodes occurred on the side opposite to the MMC application. This difference was not statistically significant. The topical application of MMC did not decrease the incidence of stenosis and synechia formation after ESS.

A growing interest in posttraumatic growth among individuals who have experienced a traumatic event has given rise to measures such as the Posttraumatic Growth Inventory (PTGI; Tedeschi and Calhoun, 1996). However, such measures may not fully represent all dimensions of change among individuals diagnosed with a chronic disease and fail to highlight the negative changes that may also occur. This study explores the positive and negative changes patients with inflammatory bowel disease (IBD) have experienced since diagnosis. Three hundred and seventy-eight IBD patients provided answers to the qualitative question "Could you please describe the (positive/negative) effect(s) IBD has had on your life?" A grounded theory approach using NVivo was performed on participants' responses. Nearly 73 % of participants reported their disease positively affected their life in some way, and five themes related to positive changes emerged from the analysis: Interpersonal Relations, Personal Growth, Valuing Life, New Life Paths, and Spiritual Growth. However, almost 80 % of participants also reported their disease negatively affected their lives, with three themes emerging from the analysis: Freedom Restrictions, Psychological Side Effects, and Social Isolation. Our results support previous findings but also reveal that some dimensions related to the positive changes following adversity are not adequately assessed by the PTGI (e.g., appraising existing friendships, openness to try different forms of treatment or therapies, and psychological preparedness). The implications of these findings for future measurement and research of posttraumatic growth with IBD patients are discussed.

We examined whether the insertion time for colonoscopies performed after left-sided resection was different in patients with a colostomy from that in patients without a colostomy and identified factors that could impact colonoscopy performance. We included consecutive patients who underwent colonoscopy between July 2005 and March 2011 after left-sided colorectal resection for colorectal cancer. We classified surgical methods according to the presence or absence of a colostomy and evaluated colonoscope insertion time retrospectively. Furthermore, we analyzed factors that might affect insertion time. A total of 1,041 patients underwent colonoscopy after left-sided colorectal resection during the study period. The colonoscopy completion rate was 98.6 %, and the mean insertion time was 6.1 ± 4.6 min (median 4.7 min, range 0.3-35.8 min). A shorter resection length of colon, the presence of a colostomy, and a lower endoscopist case volume were found to be independent factors associated with prolonged insertion time in patients with left-sided colorectal resection. Among experienced colonoscopists, no colonoscopy-associated or clinical factors were found to affect insertion time. However, a shorter resection length of colon, the presence of a colostomy, and poor bowel preparation were associated with prolonged insertion time among inexperienced endoscopists. We identified three factors that affect colonoscope insertion time after left-sided colorectal resection, including the presence of a colostomy. Inexperienced endoscopists were much more affected by the presence of a colostomy after left-sided colorectal resection. These findings have implications for the practice and teaching of colonoscopy after left-sided colorectal resection.

Glacial Lake Expansion in the Central Himalayas by Landsat Images, 1990–2010

Glacial lake outburst flood (GLOF) is a serious hazard in high, mountainous regions. In the Himalayas, catastrophic risks of GLOFs have increased in recent years because most Himalayan glaciers have experienced remarkable downwasting under a warming climate. However, current knowledge about the distribution and recent changes in glacial lakes within the central Himalaya mountain range is still limited. Here, we conducted a systematic investigation of the glacial lakes within the entire central Himalaya range by using an object-oriented image processing method based on the Landsat Thematic Mapper (TM) or Enhanced Thematic Mapper (ETM) images from 1990 to 2010. We extracted the lake boundaries for four time points (1990, 2000, 2005 and 2010) and used a time series inspection method combined with a consistent spatial resolution of Landsat images that consistently revealed lake expansion. Our results show that the glacial lakes expanded rapidly by 17.11% from 1990 to 2010. The pre-existing, larger glacial lakes, rather than the newly formed lakes, contributed most to the areal expansion. The greatest expansions occurred at the altitudinal zones between 4800 m and 5600 m at the north side of the main Himalayan range and between 4500 m and 5600 m at the south side, respectively. Based on the expansion rate, area and type of glacial lakes, we identified 67 rapidly expanding glacial lakes in the central Himalayan region that need to be closely monitored in the future. The warming and increasing amounts of light-absorbing constituents of snow and ice could have accelerated the melting that directly affected the glacial lake expansion. Across the main central Himalayas, glacial lakes at the north side show more remarkable expansion than those at the south side. An effective monitoring and warning system for critical glacial lakes is urgently needed. PMID:24376778

The aim of the present study was to examine the effect of homonymous visual field defects (HVFDs) on collision avoidance of dynamic obstacles at an intersection under virtual reality (VR) conditions. Overall performance was quantitatively assessed as the number of collisions at a virtual intersection at two difficulty levels. HVFDs were assessed by binocular semi-automated kinetic perimetry within the 90° visual field, stimulus III4e and the area of sparing within the affected hemifield (A-SPAR in deg(2)) was calculated. The effect of A-SPAR, age, gender, side of brain lesion, time since brain lesion and presence of macular sparing on the number of collisions, as well as performance over time were investigated. Thirty patients (10 female, 20 male, age range: 19-71 years) with HVFDs due to unilateral vascular brain lesions and 30 group-age-matched subjects with normal visual fields were examined. The mean number of collisions was higher for patients and in the more difficult level they experienced more collisions with vehicles approaching from the blind side than the seeing side. Lower A-SPAR and increasing age were associated with decreasing performance. However, in agreement with previous studies, wide variability in performance among patients with identical visual field defects was observed and performance of some patients was similar to that of normal subjects. Both patients and healthy subjects displayed equal improvement of performance over time in the more difficult level. In conclusion, our results suggest that visual-field related parameters per se are inadequate in predicting successful collision avoidance. Individualized approaches which also consider compensatory strategies by means of eye and head movements should be introduced. Copyright © 2011 Elsevier Ltd. All rights reserved.

The goal of this study was to evaluate how well an in-laboratory rollover crash test methodology that constrains vehicle motion can reproduce the dynamics of unconstrained full-scale steering-induced rollover crash tests in sand. Data from previously-published unconstrained steering-induced rollover crash tests using a full-size pickup and mid-sized sedan were analyzed to determine vehicle-to-ground impact conditions and kinematic response of the vehicles throughout the tests. Then, a pair of replicate vehicles were prepared to match the inertial properties of the steering-induced test vehicles and configured to record dynamic roof structure deformations and kinematic response. Both vehicles experienced greater increases in roll-axis angular velocities in the unconstrained tests than in the constrained tests; however, the increases that occurred during the trailing side roof interaction were nearly identical between tests for both vehicles. Both vehicles experienced linear accelerations in the constrained tests that were similar to those in the unconstrained tests, but the pickup, in particular, had accelerations that were matched in magnitude, timing, and duration very closely between the two test types. Deformations in the truck test were higher in the constrained than the unconstrained, and deformations in the sedan were greater in the unconstrained than the constrained as a result of constraints of the test fixture, and differences in impact velocity for the trailing side. The results of the current study suggest that in-laboratory rollover tests can be used to simulate the injury-causing portions of unconstrained rollover crashes. To date, such a demonstration has not yet been published in the open literature. This study did, however, show that road surface can affect vehicle response in a way that may not be able to be mimicked in the laboratory. Lastly, this study showed that configuring the in-laboratory tests to match the leading-side touchdown conditions could result in differences in the trailing side impact conditions.

Refractory migraine surgery developed since 2003 has excellent results over the past 10 years. According to the pioneer of migraine surgery, Dr. Bahman Guyuron, 5 major surgical classifications of migraines are described in the field of plastic surgery, namely, frontal migraine, temporal migraine, rhinogenic migraine, occipital migraine, and auriculotemporal migraine. In this study, we present the preliminary surgical results of the occipital migraine surgery. A total of 22 patients with simple occipital migraines came to our outpatient clinic for help from June 2014 to February 2015. Thirteen cases were excluded owing to ineligibility for operation or other reasons. The patients who concurrently experienced other types of migraines were precluded even if they received combined migraine surgery. Therefore, 9 simple occipital migraine cases were enrolled in this study. Migraine severity was evaluated by uniform questionnaires to identify the source of migraine. Neurolysis was performed under general anesthesia, with the patient in a prone position. Postoperative conditions were evaluated at the second, fourth, sixth, and eighth weeks by posttreatment questionnaires. Of all the 9 patients, 5 experienced single-sided migraines of greater occipital nerve origin (2 left-sided and 3 right-sided cases). Two patients had bilateral migraines of greater occipital nerve origin, and unilateral right lesser occipital nerve origin was noted in one patient. The last patient had right-sided migraines of greater and lesser occipital nerve origin. As a result in the follow-up, a response rate greater than 90% was documented, and complete resolution was observed in 2 patients. Drug doses were reduced more than 50% in the remaining patients. The overall efficacy of occipital migraine surgery in this study was 88.8% (8/9 cases). Some patients with migraine are good candidates for surgical resolution with appropriate and meticulous selection. Similar to what is observed in Western countries, the migraine surgery is promising and could provide a better quality of life to selected refractory migraine patients in Taiwan.

1. A randomized, double-blind, placebo-controlled trial was carried out to determine the efficacy of isosorbide dinitrate (ISD) on dysphagia in patients with Chagasic achalasia. 2. Twenty-three patients with Chagas' disease and dysphagia entered the study and 20 (87%) completed the two 7-day treatment periods. Subjects were given either 5 mg ISD (12 patients) or placebo (11 patients) by the sublingual route for the first 7 days. On the 8th day, patients crossed over and began another 7-day period during which they received the opposite, identical-appearing tablets. 3. Scores attributed by uninformed investigators for the frequency and severity of dysphagia were significantly lower (P less than 0.05) following ISD treatment than after the placebo period or for the pretreatment condition. A significantly higher degree of improvement of dysphagia was experienced by the patients during ISD treatment than during the placebo period. Fourteen patients experienced meal-related headaches during ISD, but not placebo treatment. The extent of improvement in general well-being due to ISD was the same when the drug was given in the first or second test period. 4. Our results indicate that ISD, 5 mg by the sublingual route, is effective in alleviating dysphagia in patients with Chagasic achalasia but its usefulness is limited by the high rate of headache as a side effect.

There exists few pediatric data on the safety and efficacy of prophylactic antibiotics during chemotherapy-induced agranulocytosis. We prospectively studied the incidence of infection-related fever in 38 children, aged 2-16 years, with acute myeloid leukemia (AML) over 121 chemotherapy treatment cycles. A prophylactic group (n = 18) was given either vancomycin/cefepime (400 mg/m(2), q12 h/50 mg/kg, q12 h) or piperacillin/tazobactam (110 mg/kg, q12 h). Control patients (n = 20) received no preventive antibiotics. The prophylactic group (59 treatment cycles) experienced fever less frequently than the control group (0.4 vs. 0.9 events; p < 0.001), had a longer interval between agranulocytosis and fever (6.4 vs. 3.8 days; p = 0.007), had a shorter duration of hospitalization (21.5 vs. 28.5 days; p < 0.001), and had a lower rate of lung infection (38.8 vs. 80.0%; p < 0.001). One patient taking vancomycin experienced a skin rash and 3 patients taking piperacillin/tazobactam had diarrhea; these side effects subsided after antibiotics were discontinued. In children with AML, prophylactic antibiotics during the period of chemotherapy-induced agranulocytosis can effectively reduce the incidence of infectious fever and can shorten the average length of hospital stay, improving treatment success and quality of life. © 2014 S.

Anticipatory nausea (AN) is a poorly controlled side effect experienced by chemotherapy patients. Currently, pharmacotherapy is restricted to benzodiazepine anxiolytics, which have limited efficacy, have significant sedative effects and induce dependency. The non-psychoactive phytocannabinoid, cannabidiolic acid (CBDA), has shown considerable efficacy in pre-clinical AN models, however determination of its neuromotor tolerability profile is crucial to justify clinical investigation. Provisional evidence for appetite-stimulating properties also requires detailed investigation. This study aims to assess the tolerability of CBDA in locomotor activity, motor coordination and muscular strength tests, and additionally for ability to modulate feeding behaviours. Male Lister Hooded rats administered CBDA (0.05-5 mg/kg; p.o.) were assessed in habituated open field (for locomotor activity), static beam and grip strength tests. A further study investigated whether these CBDA doses modulated normal feeding behaviour. Finally, evidence of anxiolytic-like effects in the habituated open field prompted testing of 5 mg/kg CBDA for anxiolytic-like activity in unhabituated open field, light/dark box and novelty-suppressed feeding (NSF) tests. CBDA had no adverse effects upon performance in any neuromotor tolerability test, however anxiolytic-like behaviour was observed in the habituated open field. Normal feeding behaviours were unaffected by any dose. CBDA (5 mg/kg) abolished the increased feeding latency in the NSF test induced by the 5-HT1AR antagonist, WAY-100,635, indicative of anxiolytic-like effects, but had no effect on anxiety-like behaviour in the novel open field or light/dark box. CBDA is very well tolerated and devoid of the sedative side effect profile of benzodiazepines, justifying its clinical investigation as a novel AN treatment.

Orbital reconstruction in the dog, cat, and horse.

To describe an adaptable method for reconstruction of the orbit following partial orbitectomy. One horse, one cat, and four dogs. Following partial orbitectomy for removal of bone and soft tissue affected by pathologic processes, reconstruction was achieved. Cerclage wires were used to reconstitute the orbital rim and other salient facial contours involved in excisions. These wires were then covered with a prolene mesh, first inside the orbit and then outwards over the affected extraorbital areas. Thereafter, a collagen sheet was placed over the mesh. Finally, subcutis and skin were closed over the construct. All operated eyes remained visual with normal position, direction, and mobility. Eyelid function, tear production, and nasolacrimal function were preserved. Side effects were mild and temporary, but animals requiring a lateral-posterior surgical approach experienced concavity to the side of the head posterior to the orbital ligament region. One bone tumor out of three recurred. The reconstruction method presented offers excellent results tectonically, cosmetically, and functionally, even following extensive orbitectomy. By adapted application of three reconstruction steps using readily available materials, large defects may be surgically repaired. Once orbitectomy is mastered, reconstruction requires no additional specialized techniques or equipment. © 2016 American College of Veterinary Ophthalmologists.

To analyze the effect of intrathecal (IT) chemotherapy for disseminated medulloblastoma. Twenty-one patients received IT chemotherapy using the chemotherapeutic agents of methotrexate (MTX) and nitrosoureas (ACNU, MCNU) including nine patients for residual leptomeningeal lesions after initial surgery and radiation, and 12 for a recurrence with leptomeningeal dissemination. Of these 21 patients, 12 received a lumbar and/or ventricular bolus injection of the chemotherapeutic agents, one received the ventriculolumbar perfusion of the agents, and eight received both the perfusion and bolus injection. The doses ranged from 6-7 mg/m(2) of ACNU for perfusion and 3-3.5 mg/m(2) of ACNU, MCNU, or MTX for the bolus injection, and the cycles were administered from 3 to 12 times for perfusion and from 5 to 54 times for the bolus injection. The effects of chemotherapy were assessed by both radiological and cytological examinations, and the clinical symptoms were also assessed. Radiological and/or cytological responses were observed in 10 of 21 patients (47.6%), including seven cases demonstrating a complete remission. The 5-year overall survival rate and 5-year survival rate after dissemination were 61.5 and 46.4%, respectively. Five patients who received a lumbar bolus injection of nitrosoureas experienced paraplegia and double incontinence. One patient who received a ventricular injection of nitrosoureas experienced truncal ataxia. IT chemotherapy was found to be effective in some cases with refractory disseminated medulloblastoma and it seems to be an appropriate treatment choice for leptomeningeal recurrence. However, the frequent bolus injections of nitrosoureas should be avoided to prevent the side effects.

Oral metronidazole vs. Metrogel Vaginal for treating bacterial vaginosis. Cost-effectiveness evaluation.

To compare the cost-effectiveness of metronidazole versus Metrogel Vaginal in the treatment of bacterial vaginosis. Sixty consecutive patients with a clinical diagnosis of bacterial vaginosis were randomly assigned prospectively into either the metronidazole, 500 mg (twice daily for seven days by mouth) or Metrogel Vaginal (one applicator twice daily for five days) treatment group. The study patients were aged 18-30 years, without other medical problems. The patients proceeded with outpatient therapy and returned 7-10 days after the completion of treatment for reevaluation. During the study, patients refrained from sexual relations, avoided alcohol and drugs, and avoided all medication. The physician evaluated the patients for bacterial vaginosis through standard wet preparation, whiff test and pH testing prior to and after treatment. The patients were randomized by a nurse and were blinded for study purposes to the evaluating physician. Successful treatment outcomes for bacterial vaginosis occurred in 27 and 28 patients for Metrogel Vaginal and metronidazole, respectively, out of the original 30 patients in each study group. All patients introduced into the study completed the study without difficulty. No significant complications were found in either treatment group. Three patients treated with metronidazole experienced nausea during the treatment interval. The entire cost of treatment was $19.71 and $1.51 for Metrogel Vaginal and metronidazole, respectively. The most cost-effective treatment for bacterial vaginosis was generic metronidazole. While the use of the more expensive Metrogel Vaginal may be reasonable for patients experiencing side effects of oral metronidazole, most patients should be treated with the less expensive generic metronidazole.

Is Diversion with Ileostomy Non-inferior to Hartmann Resection for Left-sided Colorectal Anastomotic Leak?

Treatment of left-sided colorectal anastomotic leaks often requires fecal stream diversion for prevention of further septic complications. To manage anastomotic leak, it is unclear if diverting ileostomy provides similar outcomes to Hartmann resection with colostomy. We identified all patients who developed anastomotic leak following left-sided colorectal resections from 1/2012 through 12/2014 using the American College of Surgeons National Surgical Quality Improvement Program. Then, we examined the risk of mortality and abdominal reoperation in patients treated with diverting ileostomy as compared to Hartmann resection. There were 1745 patients who experienced an anastomotic leak in a cohort of 63,748 patients (3.7%). Two hundred thirty-five patients had a reoperation for anastomotic leak involving the formation of a diverting ileostomy (n = 77) or Hartmann resection (n = 158). There was no difference in mortality or abdominal reoperation in patients treated with diverting ileostomy (3.9, 7.8%) versus Hartmann resection (3.8, 6.3%) (p = 0.8). There was no difference in the outcomes of mortality or need for second abdominal reoperation in patients treated with diverting ileostomy as compared to Hartmann resection for left-sided colorectal anastomotic leak. Thus, select patients with left-sided colorectal anastomotic leaks may be safely managed with diverting ileostomy.

[A comparative study of three types of IUD].

Lai, K R; Chen, Q B

1991-11-01

In Zhejiang Province, China, there are 2.7 million IUD users. 90% of them use stainless steel single ring. In order to evaluate the effectiveness of the IUDs, the Provincial Family Planning Commission organized a prospective comparative study on 3 kinds of IUDs: the single ring made in Wuxi, the metal ring with plastic core made in Beijing, and the copper TCU 220c made in Tianjin. Between October 1985 and March 1986 1199 healthy women aged 20-39 who had 2 or fewer normal deliveries and without previous history of ectopic pregnancy were screened and recruited to the study. They were randomly assigned to be inserted with the IUDs. 400 women had single ring, 402 women had metal with plastic core, and 397 had TCu 220c. 8 postinsertion follow-up visits were conducted up to 3 years, and menstruations were recorded every month. During the study, 4 cases were lost to follow-up. In the single-ring group, the cumulative continuation rates at 12, 24, and 36 months were 73.4, 66.7, and 65.7% respectively. For the metal-plastic ring group, it was 80.9, 72.3, and 69.3% and for the TCu 220c group, it was 94.5, 88.4, and 83.1%, respectively. The expulsion rates among the 3 kinds of IUDs were statistically significant at 12, 24, and 36 months. The highest expulsion rates were the single ring and TCu 220c were the lowest. The pregnancy rates were highest among metal-plastic ring users and lowest among TCu 220c users. The differences were not statistically significant between single ring and metal-plastic ring users. Discontinuation due to excessive menstrual bleeding were similar among the 3 methods probably due to treatment of the users who experienced excessive bleeding. Younger women and women who experienced fewer pregnancies were found to have higher expulsion and pregnancy rates. But the occurrence of side effects such as prolonged menstrual periods, spotting, and back pain were highest among TCu 220c users. It was recommended that the more effective TCu 220c should be promoted to replace the single ring. Since different sizes of TCu IUDs have been developed, it would be possible to reduce excessive menstrual bleeding and its side effects.

Desvenlafaxine in major depressive disorder: an evidence-based review of its place in therapy

Lieberman, Daniel Z; Massey, Suena H

2010-01-01

Introduction: Desvenlafaxine, the active metabolite of venlafaxine, is a serotonin norepinephrine reuptake inhibitor (SNRI) recently approved for the treatment of major depressive disorder. It is one of only three medications in this class available in the United States. Aims: The objective of this article is to review the published evidence for the safety and efficacy of desvenlafaxine, and to compare it to other antidepressants to delineate its role in the treatment of depression. Evidence review: At the recommended dose of 50 mg per day the rate of response and remission was similar to other SNRIs, as was the adverse effect profile. The rate of discontinuation was no greater than placebo, and a discontinuation syndrome was not observed at this dose. Higher doses were not associated with greater efficacy, but they did lead to more side effects, and the use of a taper prior to discontinuation. The most common side effects reported were insomnia, somnolence, dizziness, and nausea. Some subjects experienced clinically significant blood pressure elevation. Place in therapy: Like duloxetine, desvenlafaxine inhibits the reuptake of both norepinephrine and serotonin at the starting dose. Dual reuptake inhibitors have been shown to have small but statistically significantly greater rates of response and remission compared to selective serotonin reuptake inhibitors, and they have also shown early promise in the treatment of neuropathic pain. Desvenlafaxine may prove to be a valuable treatment option by expanding the limited number of available dual reuptake inhibitors. PMID:20694066

The treatment of chronic pain could benefit from additional non-opioid interventions. Virtual reality (VR) has been shown to be effective in decreasing pain for procedural or acute pain but to date there have been few studies on its use in chronic pain. The present study was an investigation of the impact of a virtual reality application for chronic pain. Thirty (30) participants with various chronic pain conditions were offered a five-minute session using a virtual reality application called Cool! Participants were asked about their pain using a 0-10 visual analog scale rating before the VR session, during the session and immediately after the session. They were also asked about immersion into the VR world and about possible side effects. Pain was reduced from pre-session to post-session by 33%. Pain was reduced from pre-session during the VR session by 60%. These changes were both statistically significant at the p < .001 level. Three participants (10%) reported no change between pre and post pain ratings. Ten participants (33%) reported complete pain relief while doing the virtual reality session. All participants (100%) reported a decrease in pain to some degree between pre-session pain and during-session pain. The virtual reality experience was found here to provide a significant amount of pain relief. A head mounted display (HMD) was used with all subjects and no discomfort was experienced. Only one participant noted any side effects. VR seems to have promise as a non-opioid treatment for chronic pain and further investigation is warranted.

Reduced itraconazole concentration and durations are successful in treating Batrachochytrium dendrobatidis infection in amphibians.

Amphibians are experiencing the greatest decline of any vertebrate class and a leading cause of these declines is a fungal pathogen, Batrachochytrium dendrobatidis (Bd), which causes the disease chytridiomycosis. Captive assurance colonies are important worldwide for threatened amphibian species and may be the only lifeline for those in critical threat of extinction. Maintaining disease free colonies is a priority of captive managers, yet safe and effective treatments for all species and across life stages have not been identified. The most widely used chemotherapeutic treatment is itraconazole, although the dosage commonly used can be harmful to some individuals and species. We performed a clinical treatment trial to assess whether a lower and safer but effective dose of itraconazole could be found to cure Bd infections. We found that by reducing the treatment concentration from 0.01-0.0025% and reducing the treatment duration from 11-6 days of 5 min baths, frogs could be cured of Bd infection with fewer side effects and less treatment-associated mortality.

A double-blind placebo-controlled study compared the efficacy of the antimotion sickness drug scopolamine when administered by oral or transdermal routes. A secondary purpose was to extend our bioassay involving fixed-dose combinations of the homergic drugs promethazine and ephedrine. After receiving 12 apparently identical drug-placebo treatments, eight normal male students were exposed in a slow rotation room to stressful accelerations generated by their execution of 40 head movements out of the plane of the room's rotation at 1 rpm and at 1-rpm increments until either symptoms were experienced (just short of frank motion sickness) or the 27-rpm ceiling on the test was reached. Efficacy of a drug was defined in terms of the placebo-range and categorized as beneficial, inconsequential, or detrimental. The only detrimental effect was with scopolamine given orally. It is concluded that the advantages of the transdermal scopolamine, which include minimal side effects and prolonged effectiveness, deserve full exploitation.

This study investigated the effectiveness of traditional contraceptives commonly used by Yoruba women, and the attitudes of users and non-users towards family planning services and contraceptives in Nigeria. One hundred forty-two married women aged 19 to 40 years were followed for 18 months. Seventy-two of the women were identified as current users of four types of traditional contraceptives (ring, incision, soup, and waistband types), and 70 women did not use any type of contraceptive. The users and non-users were matched on socio-demographic characteristics. Attitudes of the users and non-users towards fertility regulation were investigated using focus group discussions. The study found that 5.6 percent of the users and 34.5 percent of the non-users became pregnant during the follow-up period. Contraceptive failure was experienced by users of the waistband and ring methods. The main barriers to the use of modern contraceptives as described by women were the negative attitudes of men and the fear of side effects.

Drug side effects are one of main concerns in the drug discovery, which gains wide attentions. Investigating drug side effects is of great importance, and the computational prediction can help to guide wet experiments. As far as we known, a great number of computational methods have been proposed for the side effect predictions. The assumption that similar drugs may induce same side effects is usually employed for modeling, and how to calculate the drug-drug similarity is critical in the side effect predictions. In this paper, we present a novel measure of drug-drug similarity named "linear neighborhood similarity", which is calculated in a drug feature space by exploring linear neighborhood relationship. Then, we transfer the similarity from the feature space into the side effect space, and predict drug side effects by propagating known side effect information through a similarity-based graph. Under a unified frame based on the linear neighborhood similarity, we propose method "LNSM" and its extension "LNSM-SMI" to predict side effects of new drugs, and propose the method "LNSM-MSE" to predict unobserved side effect of approved drugs. We evaluate the performances of LNSM and LNSM-SMI in predicting side effects of new drugs, and evaluate the performances of LNSM-MSE in predicting missing side effects of approved drugs. The results demonstrate that the linear neighborhood similarity can improve the performances of side effect prediction, and the linear neighborhood similarity-based methods can outperform existing side effect prediction methods. More importantly, the proposed methods can predict side effects of new drugs as well as unobserved side effects of approved drugs under a unified frame.

Objective To extract physician-asserted drug side effects from electronic medical record clinical narratives. Materials and methods Pattern matching rules were manually developed through examining keywords and expression patterns of side effects to discover an individual side effect and causative drug relationship. A combination of machine learning (C4.5) using side effect keyword features and pattern matching rules was used to extract sentences that contain side effect and causative drug pairs, enabling the system to discover most side effect occurrences. Our system was implemented as a module within the clinical Text Analysis and Knowledge Extraction System. Results The system was tested in the domain of psychiatry and psychology. The rule-based system extracting side effects and causative drugs produced an F score of 0.80 (0.55 excluding allergy section). The hybrid system identifying side effect sentences had an F score of 0.75 (0.56 excluding allergy section) but covered more side effect and causative drug pairs than individual side effect extraction. Discussion The rule-based system was able to identify most side effects expressed by clear indication words. More sophisticated semantic processing is required to handle complex side effect descriptions in the narrative. We demonstrated that our system can be trained to identify sentences with complex side effect descriptions that can be submitted to a human expert for further abstraction. Conclusion Our system was able to extract most physician-asserted drug side effects. It can be used in either an automated mode for side effect extraction or semi-automated mode to identify side effect sentences that can significantly simplify abstraction by a human expert.

What matters when judging intentionality-moral content or normative status? Testing the rational scientist model of the side-effect.

PubMed

Papadopoulos, C; Hayes, B K

2018-06-01

Previous work has demonstrated a "side-effect effect," such that intentionality is more likely to be attributed to agents who bring about negatively valenced as opposed to positively valenced side effects. The rational-scientist model explains this by suggesting that norm-violating side effects are more informative for inferring intentionality than norm-conforming side effects. In the present study we reexamined this account, addressing limitations of previous empirical tests (e.g., Uttich & Lombrozo, Cognition 116: 87-100, 2010). Side-effect valence and norm status were manipulated factorially, enabling an examination of the impact of norm status on intentionality judgments in both positively and negatively valenced side effects. Additionally, the impact of side-effect norm status on the perceived valences of side effects and agents was examined. Effects of norm status were found for both positive and negative side effects. Violation of an ostensibly neutral norm led to negative perceptions of the side effect. However, a norm status effect on intentionality judgments persisted when these effects were controlled. These results support the view that the side-effect effect is the result of the rational use of social-cognitive evidence.

Aim Chemotherapy side effects are often reported in clinical trials; however, there is little evidence about their incidence in routine clinical care. The objective of this study was to describe the frequency and severity of patient-reported chemotherapy side effects in routine care across treatment centres in Australia. Methods We conducted a prospective cohort study of individuals with breast, lung or colorectal cancer undergoing chemotherapy. Side effects were identified by patient self-report. The frequency, prevalence and incidence rates of side effects were calculated by cancer type and grade, and cumulative incidence curves for each side effect computed. Frequencies of side effects were compared between demographic subgroups using chi-squared statistics. Results Side effect data were available for 449 eligible individuals, who had a median follow-up of 5.64 months. 86% of participants reported at least one side effect during the study period and 27% reported a grade IV side effect, most commonly fatigue or dyspnoea. Fatigue was the most common side effect overall (85%), followed by diarrhoea (74%) and constipation (74%). Prevalence and incidence rates were similar across side effects and cancer types. Age was the only demographic factor associated with the incidence of side effects, with older people less likely to report side effects. Conclusion This research has produced the first Australian estimates of self-reported incidence of chemotherapy side effects in routine clinical care. Chemotherapy side effects in routine care are common, continue throughout chemotherapy and can be serious. This work confirms the importance of observational data in providing clinical practice-relevant information to decision-makers. PMID:29016607

The pharmaceutical industry has experienced intermittent waves of mergers and acquisitions (M&As) since the 1980s and recently appeared to be in yet another wave. Previous studies indicated rather negative impacts of consolidation on research and development, suggesting that they do not necessarily lead to long-term reinforcement of research capabilities, although they may enrich the drug pipeline in the short term. However, recent studies have implied a positive side in terms of knowledge-base transfer. Further micro-organizational studies suggested that scientists learned new knowledge and approaches from partner scientists and improved their performance and innovation. These findings imply that measures for the scientist-level integration after M&As would reinforce fundamental research capabilities in the long term.

Comparison of metoprolol as hydrochlorothiazide and antihypertensive agents.

A crossover comparison of metoprolol and hydrochlorothiazide has been performed in 20 patients with mild hypertension. Both drugs caused almost identical statistically significant reduction in blood pressure of about 20 mm Hg systolic and 15 mm Hg diastolic. The side effects during active therapy were few and mild, but 5 patients experienced subjective symptoms during the first few days following abrupt withdrawal of metoprolol, namely general malaise, palpitations, headache, sweating and tremor. The symptoms were more pronounced in the standing position and disappeared at once on resumption of beta-blocker therapy, or gradually over 5 - 7 days when placebo tablets were given. In 11 of the 20 patients hydrochlorothiazide produced subnormal serum potassium levels and potassium supplements were given. The serum uric acid level was also significantly increased during hydrochlorothiazide treatment.

Conformational analysis investigation into the influence of nano-porosity of ultra-permeable ultra-selective polyimides on its diffusivity as potential membranes for use in the "green" separation of natural gases

NASA Astrophysics Data System (ADS)

Madkour, Tarek M.

2013-08-01

Nano-porous polymers of intrinsic microporosity, PIM, have exhibited excellent permeability and selectivity characteristics that could be utilized in an environmentally friendly gas separation process. A full understanding of the mechanism through which these membranes effectively and selectively allow for the permeation of specific gases will lead to further development of these membranes. Three factors obviously influenced the conformational behavior of these polymers, which are the presence of electronegative atoms, the presence of non-linearity in the polymeric backbones (backbone kinks) and the presence of bulky side groups on the polymeric chains. The dipole moment increased sharply with the presence of backbone kinks more than any other factor. Replacing the fluorine atoms with bulky alkyl groups didn't influence the dipole moment greatly indicating that the size of the side chains had much less dramatic influence on the dipole moment than having a bent backbone. Similarly, the presence of the backbone kinks in the polymeric chains influenced the polymeric chains to assume less extended configuration causing the torsional angles around the interconnecting bonds unable to cross the high potential energy barriers. The presence of the bulky side groups also caused the energy barriers of the cis-configurations to increase dramatically, which prevented the polymeric segments from experiencing full rotation about the connecting bonds. For these polymers, it was clear that the fully extended configurations are the preferred configurations in the absence of strong electronegative atoms, backbones kinks or bulky side groups. The addition of any of these factors to the polymeric structures resulted in the polymeric chains being forced to assume less extended configurations. Rather interestingly, the length or bulkiness of the side groups didn't affect the end-to-end distance distribution to a great deal since the presence of quite large bulky side chain such as the pentyl group has caused the polymeric chains to revert back to the fully extended configurations possibly due to the quite high potential energy barriers that the chains have to cross to reach the less extended configurational states.

The correlation between subjective and objective outcomes of nasal obstruction is still a matter of controversy. The aim of this study was to determine the minimal level of side difference in nasal airway resistance (NAR measured by Broms'v(2)) between the two nasal cavities, which could be discerned subjectively by the patient on a visual analogue scale (VAS). Nasal airway resistance was calculated from rhinomanometric measurements of nasal airflow and transnasal pressure after decongestion of the nasal mucosa. A retrospective study. ENT department, Vaxjo Central Hospital, Sweden. We studied 1000 active anterior rhinomanometries from patients with nasal obstructions. We compared the side difference of nasal airway resistance with the side difference of VAS estimated immediately prior to the rhinomanometry. Each measurement was performed after nasal decongestion. When the difference in nasal airway resistance between the two nasal cavities was larger than 20° (Broms'v(2)) or R(2) > 0.36 Pa/cm(3) /s, we found a significant correlation between side differences of the objective measurement and the subjective assessment (VAS). With a nasal airway resistance side difference over 20°, an additional 20° difference corresponded to a 0.9 centimetre average VAS change. The more obstructed side of the nose could be determined by VAS in 823 (82.3%) of 1000 patients. Yet, 177 (17.7%) patients had a paradoxical sensation of nasal obstruction with the low resistance side of the nose experienced as the most congested side. A significant correlation between the side differences of nasal airway resistance and VAS can serve as a supplement to rhinoscopy in decisions about nasal surgery. This study also showed that in 17.7% of patients, there was a negative correlation between subjective and objective evaluations of nasal airway resistance. But in this group, the nasal airway resistance side difference was mostly under 20°. © 2011 Blackwell Publishing Ltd.

Sirolimus is used in cardiac transplant recipients to prevent rejection, progression of cardiac allograft vasculopathy, and renal dysfunction. However, sirolimus has many potential side effects and its tolerability when used outside of clinical trials is not well established. We describe a decade of experience with sirolimus in cardiac transplant recipients at our institution. We retrospectively reviewed records of all adult cardiac transplant recipients living between September 1999 and February 2010 (n = 329) and identified 67 patients (20%) who received sirolimus. The indications for sirolimus were cardiac allograft vasculopathy (67%), renal dysfunction (25%), rejection (4%), and intolerability of tacrolimus (3%). One-third of patients discontinued sirolimus at a median (25th, 75th percentiles) of 0.9 (0.2, 1.6) yr of duration. Over 70% of subjects experienced an adverse event attributed to sirolimus. Adverse events were associated with higher average sirolimus levels (9.1 ng/mL vs. 7.1 ng/mL, p = 0.004). We conclude that sirolimus is frequently used in cardiac transplant recipients (20%) and commonly causes side effects, often necessitating discontinuation. Higher average sirolimus levels were associated with adverse events, suggesting that tolerability may improve if levels are maintained within the lower end of the current therapeutic range; however, the improvement in tolerability would need to be balanced with the potential for decreased efficacy. © 2013 John Wiley & Sons A/S.

Radiation proctitis is a side effect which can occur after pelvic radiation therapy. Currently available questionnaires do not comprehensively assess the range of problems, nor impact on quality of life associated with proctitis. This article reports on the cultural testing phase of an EORTC module (QLQ-PRT21) developed to assess radiation proctitis specific issues and designed to be used in conjunction with the EORTC core quality of life questionnaire (QLQ-C30). The previously developed 21-item module, pre-tested in Australia, was translated into Norwegian, German, French and Italian. Patients completed the EORTC QLQ-C30 and module questionnaires towards the end of their radical pelvic radiation treatment to target acute side effects. Patients experiencing chronic proctitis were also surveyed. Patients also participated in structured interviews to determine issues of comprehensibility, coverage and relevance. Results were compared with Australian data. Questionnaires were completed by 64 European patients. The module was found to be relevant and culturally acceptable to participants. Feedback has led to minor translation modifications and the inclusion of two additional questions. This module is ready for Phase IV testing which will consist of large scale field testing with the aim to perform psychometric analysis and finalize a module that will be suitable in the assessment of radiation induced proctitis.

To evaluate the efficacy and tolerability of levetiracetam monotherapy in dogs with structural epilepsy. Retrospective case series. Nineteen client-owned dogs with structural epilepsy. Seizure frequencies after initiation of treatment were used to evaluate the efficacy of levetiracetam monotherapy. Seizure control was considered good if no seizures occurred within three months of starting treatment or poor if seizures returned within one month of starting treatment. Tolerability was evaluated by considering the occurrence and severity of any reported side effects. Ten of the 19 dogs were considered to have a good response to treatment with 7 achieving complete seizure freedom. Nine dogs were considered to have poor response to treatment. There was a statistically significant reduction in the percentage of patients experiencing cluster seizures from 68.4% to 15.8% (p=0.002). Side effects were noted in 8 of the 19 dogs but were considered mild in all cases. Follow-up times ranged from 12 days to 426 days. When used in conjunction with other appropriate therapies, levetiracetam may be an efficacious option for monotherapy in dogs with structural epilepsy. Its tolerability makes it a suitable option for use in a wide variety of patients. © British Veterinary Association (unless otherwise stated in the text of the article) 2017. All rights reserved.

Respiratory syncytial virus (RSV) is the leading cause of acute lower respiratory tract infections in infants and young children. There are no licensed RSV vaccines available, and the few treatment options for high-risk individuals are either extremely costly or cause severe side effects and toxicity. Immunomodulation mediated by a novel formulation consisting of the toll-like receptor 3 agonist poly(I:C), an innate defense regulator peptide and a polyphosphazene (P-I-P) was evaluated in the context of lethal infection with pneumonia virus of mice (PVM). Intranasal delivery of a single dose of P-I-P protected adult mice against PVM when given 24 h prior to challenge. These animals experienced minimal weight loss, no clinical disease, 100% survival, and reduced lung pathology. Similar clinical outcomes were observed in mice treated up to 3 days prior to infection. P-I-P pre-treatment induced early mRNA and protein expression of key chemokine and cytokine genes, reduced the recruitment of neutrophils and eosinophils, decreased virus titers in the lungs, and modulated the delayed exacerbated nature of PVM disease without any short-term side effects. On day 14 post-infection, P-I-P-treated mice were confirmed to be PVM-free. These results demonstrate the capacity of this formulation to prevent PVM and possibly other viral respiratory infections.

Governments and donors are investing in climate compatible development in order to reduce climate and development vulnerabilities. However, the rate at which climate compatible development is being operationalised has outpaced academic enquiry into the concept. Interventions aiming to achieve climate compatible development "wins" (for development, mitigation, adaptation) can also create negative side-effects. Moreover, benefits and negative side-effects may differ across time and space and have diverse consequences for individuals and groups. Assessments of the full range of outcomes created by climate compatible development projects and their implications for distributive justice are scarce. This article develops a framework using a systematic literature review that enables holistic climate compatible development outcome evaluation over seven parameters identified. Thereafter, we explore the outcomes of two donor-funded projects that pursue climate compatible development triple-wins in Malawi using this framework. Household surveys, semi-structured interviews and documentary material are analysed. Results reveal that uneven outcomes are experienced between stakeholder groups and change over time. Although climate compatible development triple-wins can be achieved through projects, they do not represent the full range of outcomes. Ecosystem—and community-based activities are becoming popularised as approaches for achieving climate compatible development goals. However, findings suggest that a strengthened evidence base is required to ensure that these approaches are able to meet climate compatible development goals and further distributive justice.

The present study assessed the prevalence of adverse drug reactions (ADRs) among HIV positive patients taking antiretroviral therapy referred to Imam Khomeini Hospital in Tehran, Iran. This is a cross sectional study regarding side effects of Highly Active Antiretroviral Therapy (HAART) in HIV positive patients referred to Voluntary Counseling and Testing (VCT) center in Imam Khomeini Hospital of Tehran, Iran during a period of the year 2009 to 2010. Two hundred patients under antiretroviral treatment evaluated for the side effects of drug based on available records, face to face interviews and written lab data. Data was collected from a sample of 200 HIV positive patients (72% male). Injection drug use was the most common route of HIV transmission. Co-Infections with Hepatitis C virus (HCV) found in the majority of patients (60.5%). Tuberculosis was the most prevalent opportunistic infection. One hundred eighty eight (94%) patients experienced at least one adverse drug reaction. The most frequent clinical and paraclinical findings were skin rash (28%) and abnormal liver function tests (36%). Given the high prevalence of adverse drug reactions among HIV positive patients taking antiretroviral therapy (ART) in this study, clinicians should be aware of ADRs at the initiation of ART as complications can affect patients' adherence to the therapy.

Combination therapy of intranasal tumours in dogs with palliative 60 cobalt radiation and carboplatin chemotherapy. Twenty-five dogs with intranasal tumours were treated in the Hofheim Veterinary Hospital (Germany) from 2004 to 2006 with a total radiation dose of 24Gy (3 fractions of 8 Gy on days 0, 7 and 21) and five doses of Carboplatin (270-300 mg/m² BSA i.v. every 21-28 days). In 88% patients, clinical symptoms subsided partially or completely resulting in improvement in quality of life. Computed tomography revealed partial (5/25) or complete (5/25) tumour remissions. Chemotherapy was well tolerated. Radiation therapy caused no or minimal side effects except for 3 dogs (12%), which experienced serious ocular side effects resulting in loss of vision of the affected eye and one dog with epileptic seizures. Survival times ranged from 10-639 days with a median of 156 days. There was no statistically significant correlation between the parameters breed, age, sex, brain invasion or tumour stage and survival time or progression free interval. Survival time and progression free interval were significantly correlated with the degree of tumour remission. It can be concluded from this study that palliative radiation therapy combined with chemotherapy results in excellent palliation of clinical symptoms and acceptable survival times. There was no advantage of combined therapy (radiation with carboplatin) when compared to literature data on results of radiation therapy alone.

A sensor has a plurality of carbon nanotube (CNT)-based conductors operatively positioned on a substrate. The conductors are arranged side-by-side, such as in a substantially parallel relationship to one another. At least one pair of spaced-apart electrodes is coupled to opposing ends of the conductors. A portion of each of the conductors spanning between each pair of electrodes comprises a plurality of carbon nanotubes arranged end-to-end and substantially aligned along an axis. Because a direct correlation exists between resistance of a carbon nanotube and carbon nanotube strain, changes experienced by the portion of the structure to which the sensor is coupled induce a change in electrical properties of the conductors.

Arc fault detection system

1999-05-18

An arc fault detection system for use on ungrounded or high-resistance-grounded power distribution systems is provided which can be retrofitted outside electrical switchboard circuits having limited space constraints. The system includes a differential current relay that senses a current differential between current flowing from secondary windings located in a current transformer coupled to a power supply side of a switchboard, and a total current induced in secondary windings coupled to a load side of the switchboard. When such a current differential is experienced, a current travels through a operating coil of the differential current relay, which in turn opens an upstream circuit breaker located between the switchboard and a power supply to remove the supply of power to the switchboard. 1 fig.

We compared the tolerability and efficacy of intranasal subdissociative ketamine to intranasal fentanyl for analgesia of children with acute traumatic pain and investigated the feasibility of a larger noninferiority trial that could investigate the potential opioid-sparing effects of intranasal ketamine. This randomized controlled trial compared 1 mg/kg intranasal ketamine to 1.5 μg/kg intranasal fentanyl in children 4 to 17 years old with acute pain from suspected isolated extremity fractures presenting to an urban Level II pediatric trauma center from December 2015 to November 2016. Patients, parents, treating physicians, and outcome assessors were blinded to group allocation. The primary outcome, a tolerability measure, was the frequency of cumulative side effects and adverse events within 60 minutes of drug administration. The secondary outcomes included the difference in mean pain score reduction at 20 minutes, the proportion of patients achieving a clinically significant reduction in pain in 20 minutes, total dose of opioid pain medication in morphine equivalents/kg/hour (excluding study drug) required during the emergency department (ED) stay, and the feasibility of enrolling children presenting to the ED in acute pain into a randomized trial conducted under U.S. regulations. All patients were monitored until 6 hours after their last dose of study drug or until admission to the hospital ward or operating room. Of 629 patients screened, 87 received the study drug and 82 had complete data for the primary outcome (41 patients in each group). The median (interquartile range) age was 8 (6-11) years and 62% were male. Baseline pain scores were similar among patients randomized to receive ketamine (73 ± 26) and fentanyl (69 ± 26; mean difference [95% CI] = 4 [-7 to 15]). The cumulative number of side effects was 2.2 times higher in the ketamine group, but there were no serious adverse events and no patients in either group required intervention. The most common side effects of ketamine were bad taste in the mouth (37; 90.2%), dizziness (30; 73.2%), and sleepiness (19; 46.3%). The most common side effects of fentanyl were sleepiness (15; 36.6%), bad taste in the mouth (9; 22%), and itchy nose (9; 22%). No patients experienced respiratory side effects. At 20 minutes, the mean pain scale score reduction was 44 ± 36 for ketamine and 35 ± 29 for fentanyl (mean difference = 9 [95% CI = -4 to 23]). Procedural sedation with ketamine occurred in 28 ketamine patients (65%) and 25 fentanyl patients (57%) prior to completing the study. Intranasal ketamine was associated with more minor side effects than intranasal fentanyl. Pain relief at 20 minutes was similar between groups. Our data support the feasibility of a larger, noninferiority trial to more rigorously evaluate the safety, efficacy, and potential opioid-sparing benefits of intranasal ketamine analgesia for children with acute pain. © 2017 by the Society for Academic Emergency Medicine.

Side effects associated with anti-HIV drugs.

Many side effects are associated with the use of anti-HIV drugs, impacting the development of drug resistance and the quality of life for HIV-patients. Concern about side effects is a primary factor in deterring people from beginning HIV therapy. Frequency and severity of side effects vary greatly, but they are frequently more common and severe in people who are taking a new drug or who have advanced HIV disease. Information on side effects comes largely from clinical trials; however, many side effects are not discovered until the drug has been approved and used by larger numbers of people. Side effects vary from serious toxicities that require stopping treatment to uncomfortable or annoying side effects that interfere with daily life. A table categorizes the four major side effects (nausea, fever, skin rash, and fatigue) and divides them into grades that describe their intensity. A chart lists the side effects associated with specific anti-HIV drugs. Suggestions for managing side effects are included.

Initial registration studies of perampanel (PMP), an AMPA receptor antagonist, have now been followed up by 'clinical' studies that confirmed its efficacy and safety in patients with refractory epilepsy. Publications on the use of PMP among patients with intellectual disability (ID) are still limited. This study extends our knowledge with respect to the relevance of PMP for patients with both ID and epilepsy, and furthermore specifies the behavioral side effects of PMP in this specific population. Retrospective evaluation of medical records at 3, 6 and 12months of follow-up after the initial start of PMP. 62 patients were included. 21 patients (33.9%) were female. All patients had complete data of 6months follow-up and we were able to review 42 patients with a 1-year follow-up. Level of ID varied from borderline to profound, and mild ID was most common (43.5%). The mean maximum daily dosage of PMP was 5.6mg (range 1-12mg). Retention rates for PMP were 87.1% and 67.7% after three and six months. A trend indicated a longer mean retention time in patients with a more severe ID (borderline-mild-moderate ID: 205days, severe-profound ID: 275days). Seizure reduction was achieved in 53.2%. 36 patients (58.1%) experienced adverse effects, 80.6% of those within 3months. 45.2% of the patients experienced somatic adverse effects. Most common were fatigue & sleep problems, motor problems & unsteadiness, and gastrointestinal problems. Behavioral adverse effects were present in 40.3%. Most common were aggression, agitated behavior, disruptive behavior, and mood symptoms. Reasons for discontinuation of PMP were lack of efficacy in 14.8%, intolerable adverse effects in 44.4%, and a combination of both in 40.7%. Altogether, 24.2% (15/62) of the patients achieved seizure reduction without experiencing adverse effects, though none reached seizure freedom. The use of PMP might lead to an effective seizure reduction without adverse effects in a minority of patients with both epilepsy and ID. Pre-existing behavioral problems or polypharmacy do not predict the occurrence of additional behavioral adverse effects, implying that these patients need not be excluded from the introduction of PMP when clinically indicated. Patients should, ideally, be monitored at a multidisciplinary clinic. Copyright © 2016 Elsevier Inc. All rights reserved.

Canine nasal tumors are typically treated with radiation therapy but most patients develop local recurrence. Our purpose was to evaluate tumor and normal tissue response to reirradiation in nine dogs. The median dose delivered with the first protocol was 50 Gy (range 44-55 Gy) and the median fraction number was 18 (range 15-20). For the second protocol, the median dose was lower intentionally, median of 36 Gy (range 23-44 Gy), without changing the median fraction number of 18 (range 14-20) to avoid late effects. The median time between protocols was 539 days (range 258-1652 days). Median survival was 927 days (95% confidence interval [CI] 423-1767 days). Median time to progression following the first and second courses was 513 days (95% CI 234-1180 days) and 282 days (95% CI 130-453 days), respectively. These were not significantly different (P=0.086). The qualitative response assessment was better for the first course compared with the second (P=0.018). Severity and timing of skin, mucous membrane, and ocular effects were similar for early side effects between the two courses (P>0.05 for all comparisons). All dogs experienced some late side effects, with two out of nine being classified as severe. These severe effects were blindness in each dog, possibly related to tumor recurrence. Reirradiation of canine nasal tumors resulted in a second clinical remission in eight of nine dogs, although the second response was less complete. Acute and late effects for seven of nine patients were not life threatening, indicating that reirradiation of canine nasal tumors may be a viable treatment option after recurrence. © 2010 Veterinary Radiology & Ultrasound.

Morphine and other opioids is the mainstay of cancer pain management. However, considerable fears surrounding their use present barriers to pain control. The aim of this study was to assess the rational use and effectiveness of morphine for management of pain in the palliative care of cancer patients at Ocean Road Cancer Institute (ORCI) in Tanzania. A total of 100 cancer patients who were receiving morphine therapy at the ORCI were interviewed to get information on morphine use. In addition, information on the prescribed doses of morphine was obtained from medical records of 200 patients who have used morphine from September 2005 to April 2006. Both outpatients and inpatients with advanced cancer who were receiving morphine for palliative care were involved. Seven (7) palliative caregivers, including two doctors, two nurses, a pharmacist, a pharmaceutical technician and a social worker were also interviewed. Of the 100 interviewees, 37% were aware of morphine. The level of education and duration of therapy had an impact on the awareness. The results also showed that oral morphine solution was the most common route (96%) of administration. Fifty-seven percent of the patients described the doses of morphine given to be effective in relieving their pain. Although most patients (79%) experienced morphine-induced side effects, the majority (93%) were continuing with the therapy. There were no indication of irrational use of morphine and morphine-induced side effects were well managed. The majority of patients and caregivers had positive attitude towards the use of morphine. In conclusion, the study revealed that the use of morphine is acceptable among a large proportion of patients receiving palliative care and that the majority of them find the doses given effective to relieve their pain.

To evaluate the efficacy and safety of armodafinil in the treatment of fatigue in HIV+ patients, and to assess its effect on depressive symptoms and behavior once fatigue remitted. HIV+ patients with clinically significant fatigue were treated in a placebo-controlled randomized double-blind trial for 4 weeks. Armodafinil responders and placebo non-responders or relapsers were treated openly for a total of 16 weeks with armodafinil. The primary outcome measure for fatigue and depression was the Clinical Global Impressions-Improvement Scale, supplemented by the Fatigue Severity Scale, the Hamilton Depression Rating Scale, and the Beck Depression Inventory. Safety was assessed with assays of CD4 cell count and HIV RNA viral load and the SAFTEE side effects rating scale. Maximum trial dose of armodafinil was 250 mg/d. Seventy patients were enrolled. Attrition was 9%. In intention-to-treat analyses, fatigue response rate to armodafinil was 75% and to placebo, 26%. Armodafinil did not reduce depressive symptoms in the absence of improved energy, but of those patients with an Axis I depressive disorder at study entry whose energy improved, 82% experienced improved mood as well. Markers of immunologic suppression did not change during treatment. At 6 months, those still taking armodafinil had more energy and fewer depressive symptoms than those who were no longer taking it. As we found in our RCT of modafinil, armodafinil appears effective and well tolerated in treating fatigue in HIV+ patients. Side effects were minimal and most patients reported substantially improved energy and mood. Copyright © 2011 The Academy of Psychosomatic Medicine. Published by Elsevier Inc. All rights reserved.

Freezing of gait (FOG) remains one of the most common debilitating aspects of Parkinson's disease and has been linked to injuries, falls and reduced quality of life. Although commercially available portable cueing devices exist claiming to assist with overcoming freezing; their immediate effectiveness in overcoming gait initiation failure is currently unknown. This study investigated the effects of three different types of cueing device in people with Parkinson's disease who experience freezing. Twenty participants with idiopathic Parkinson's disease who experienced freezing during gait but who were able to walk short distances indoors independently were recruited. At least three attempts at gait initiation were recorded using a 10 camera Qualisys motion analysis system and four force platforms. Test conditions were; Laser Cane, sound metronome, vibrating metronome, walking stick and no intervention. During testing 12 of the 20 participants had freezing episodes, from these participants 100 freezing and 91 non-freezing trials were recorded. Clear differences in the movement patterns were seen between freezing and non-freezing episodes. The Laser Cane was most effective cueing device at improving the forwards/backwards and side to side movement and had the least number of freezing episodes. The walking stick also showed significant improvements compared to the other conditions. The vibration metronome appeared to disrupt movement compared to the sound metronome at the same beat frequency. This study identified differences in the movement patterns between freezing episodes and non-freezing episodes, and identified immediate improvements during gait initiation when using the Laser Cane over the other interventions.

Emergency Department (ED) headache patients are commonly treated with neuroleptic antiemetics like metoclopramide. Haloperidol has been shown to be effective for migraine treatment. Our study compared the use of metoclopramide vs. haloperidol to treat ED migraine patients. A prospective, double-blinded, randomized control trial of 64 adults aged 18-50 years with migraine headache and no recognized risks for QT-prolongation. Haloperidol 5 mg or metoclopramide 10 mg was given intravenously after 25 mg diphenhydramine. Pain, nausea, restlessness (akathisia), and sedation were assessed with 100-mm visual analog scales (VAS) at baseline and every 20 min, to a maximum of 80 min. The need for rescue medications, side effects, and subject satisfaction were recorded. QTc intervals were measured prior to and after treatment. Follow-up calls after 48 h assessed satisfaction and recurrent or persistent symptoms. Thirty-one subjects received haloperidol, 33 metoclopramide. The groups were similar on all VAS measurements, side effects, and in their satisfaction with therapy. Pain relief averaged 53 mm VAS over both groups, with equal times to maximum improvement. Subjects receiving haloperidol required rescue medication significantly less often (3% vs. 24%, p < 0.02). Mean QTcs were equal and normal in the two groups and did not change after treatment. In telephone follow-up, 90% of subjects contacted were "happy with the medication" they had received, with haloperidol-treated subjects experiencing more restlessness (43% vs. 10%). Intravenous haloperidol is as safe and effective as metoclopramide for the ED treatment of migraine headaches, with less frequent need for rescue medications. Published by Elsevier Inc.

Side effects prompt some patients to forego otherwise-beneficial therapies. This study explored which characteristics make side effects particularly aversive. We used a psychometric approach, originating from research on risk perception, to identify the factors (or components) underlying side effect perceptions. Women ( N = 149) aged 40 to 74 years were recruited from a patient registry to complete an online experiment. Participants were presented with hypothetical scenarios in which an effective and necessary medication conferred a small risk of a single side effect (e.g., nausea, dizziness). They rated a broad range of side effects on several characteristics (e.g., embarrassing, treatable). In addition, we collected 4 measures of aversiveness for each side effect: choosing to take the medication, willingness to pay to avoid the side effect (WTP), negative affective attitude associated with the side effect, and how each side effect ranks among others in terms of undesirability. A principal components analysis (PCA) was used to identify the components underlying side effect perceptions. Then, for each aversiveness measure separately, regression analyses were used to determine which components predicted differences in aversiveness among the side effects. The PCA revealed 4 components underlying side effect perceptions: affective challenge (e.g., frightening), social challenge (e.g., disfiguring), physical challenge (e.g., painful), and familiarity (e.g., common). Side effects perceived as affectively and physically challenging elicited the highest levels of aversiveness across all 4 measures. Understanding what side effect characteristics are most aversive may inform interventions to improve medical decisions and facilitate the translation of novel biomedical therapies into clinical practice.

Pathogenic variants involving the CDKL5 gene result in a severe epileptic encephalopathy, often later presenting with features similar to Rett syndrome. Cardinal features of epilepsy in the CDKL5 disorder include early onset at a median age of 6 weeks and poor response to antiepileptic drugs. The ketogenic diet (KD) was first introduced in the 1920s as a treatment option for refractory epilepsy in children. This study investigated use of the KD in the CDKL5 disorder and its influences on seizures. The International CDKL5 Disorder Database, established in 2012, collects information on individuals with the CDKL5 disorder. Families have provided information regarding seizure characteristics, use, and side effects of the KD treatment. Descriptive statistics and time to event analyses were performed. Clinical vignettes were also provided on patients attending Boston Children's Hospital. Data regarding KD use were available for 204 individuals with a pathogenic CDKL5 variant. Median age of inclusion in the database was 4.8 years (range = 0.3-33.9 years), with median age of 6 weeks (range = 1 day-65 weeks) at seizure onset. History of KD use was reported for 51% (104 of 204) of individuals, with a median duration of use of 17 months (95% confidence interval = 9-24). Changes in seizure activity after commencing KD were reported for two-thirds (69 of 104), with improvements in 88% (61 of 69). Nearly one-third (31.7%) experienced side effects during the diet. At ascertainment, only one-third (32%) remained on the diet, with lack of long-term efficacy as the main reason for diet cessation (51%, 36 of 70). Benefits of KD in the CDKL5 disorder are in keeping with previous trials on refractory epilepsies. However, poor long-term efficacy remains as a significant barrier. In view of its side effect profile, KD administration should be supervised by a pediatric neurologist and specialist dietician. Wiley Periodicals, Inc. © 2017 International League Against Epilepsy.

Introduction Little is known about how patients weigh benefits and harms of available treatments for Parkinson’s Disease (oral medication, deep brain stimulation, infusion therapy). In this study we have (1) elicited patient preferences for benefits, side effects and process characteristics of treatments and (2) measured patients’ preferred and perceived involvement in decision-making about treatment. Methods Preferences were elicited using a best-worst scaling case 2 experiment. Attributes were selected based on 18 patient-interviews: treatment modality, tremor, slowness of movement, posture and balance problems, drowsiness, dizziness, and dyskinesia. Subsequently, a questionnaire was distributed in which patients were asked to indicate the most and least desirable attribute in nine possible treatment scenarios. Conditional logistic analysis and latent class analysis were used to estimate preference weights and identify subgroups. Patients also indicated their preferred and perceived degree of involvement in treatment decision-making (ranging from active to collaborative to passive). Results Two preference patterns were found in the patient sample (N = 192). One class of patients focused largely on optimising the process of care, while the other class focused more on controlling motor-symptoms. Patients who had experienced advanced treatments, had a shorter disease duration, or were still employed were more likely to belong to the latter class. For both classes, the benefits of treatment were more influential than the described side effects. Furthermore, many patients (45%) preferred to take the lead in treatment decisions, however 10.8% perceived a more passive or collaborative role instead. Discussion Patients weighted the benefits and side effects of treatment differently, indicating there is no “one-size-fits-all” approach to choosing treatments. Moreover, many patients preferred an active role in decision-making about treatment. Both results stress the need for physicians to know what is important to patients and to share treatment decisions to ensure that patients receive the treatment that aligns with their preferences.

Unintended pregnancy and subsequent use of modern contraceptive among slum and non-slum women in Nairobi, Kenya

PubMed Central

2014-01-01

Background In spite of major gains in contraceptive prevalence over the last few decades, many women in most parts of the developing world who would like to delay or avoid pregnancy do not use any method of contraception. This paper seeks to: a) examine whether experiencing an unintended pregnancy is associated with future use of contraception controlling for a number factors including poverty at the household and community levels; and b) investigate the mechanisms through which experiencing an unintended pregnancy leads to uptake of contraception. Methods Quantitative and qualitative data from a cross-sectional research project conducted in 2009/10 in two slum settlements and two non-slum settings of Nairobi, Kenya are used. The quantitative component of the project was based on a random sample of 1,259 women aged 15–49 years. Logistic regression models were used to assess the effect of unintended pregnancy on future contraceptive use. The qualitative component of the project successfully interviewed a total of 80 women randomly selected from survey participants who had reported having at least one unintended pregnancy. Results Women whose last pregnancy was unintended were more likely to be using a modern method of contraception, compared to their peers whose last pregnancy was intended, especially among the wealthier group as shown in the interaction model. Among poor women, unintended pregnancy was not associated with subsequent use of contraception. The qualitative investigation with women who had an unplanned pregnancy reveals that experiencing an unintended pregnancy seems to have served as a “wake-up call”, resulting in greater attention to personal risks, including increased interest in pregnancy prevention. For some women, unintended pregnancy was a consequence of strong opposition by their partners to family planning, while others reported they started using contraceptives following their unintended pregnancy, but discontinued after experiencing side effects. Conclusion This study provides quantitative and qualitative evidence that women who have had an unintended pregnancy are “ready for change”. Family planning programs may use the contacts with antenatal, delivery and post-delivery care system as an opportunity to identify women whose pregnancy is unplanned, and target them with information and services.

Falls-risk post-stroke: Examining contributions from paretic versus non paretic limbs to unexpected forward gait slips.

PubMed

Kajrolkar, Tejal; Bhatt, Tanvi

2016-09-06

Community-dwelling stroke survivors show a high incidence of falls with unexpected external perturbations during dynamic activities like walking. Previous evidence has demonstrated the importance of compensatory stepping to restore dynamic stability in response to perturbations in hemiparetic stroke survivors. However, these studies were limited to either stance perturbations or perturbation induced under the unaffected limb. This study aimed to compare the differences, if any, between the non-paretic and paretic sides in dynamic stability and protective stepping strategies when exposed to unexpected external perturbation during walking. Twenty hemiparetic subjects experienced an unexpected forward slip during walking on the laboratory walkway either on the paretic (n=10) or the nonparetic limb (n=10). Both groups demonstrated a backward loss of balance with a compensatory stepping response, with the nonparetic-side slip group resorting mainly to an aborted step response (60%) and the paretic-side slip group mainly exhibiting a recovery step response (90%). Although both groups showed an equal incidence of falls, the nonparetic-side slip group demonstrated a higher stability at recovery step touchdown, resulting from lower perturbation magnitudes (slip displacement and velocity) compared to the paretic-side slip group. The results indicate that the paretic side had difficulty initiating and executing a successful stepping response (nonparetic-side slip) and also in reactive limb control while in stance (paretic-side slip). Based on these results it is suggested that intervention strategies for fall-prevention in chronic stroke survivors should focus on paretic limb training for both reactive stepping and weight bearing for improving balance control for recovery from unpredictable perturbations during dynamic activities such as walking.

2015-01-01

The Changbai (also known as "Baekdu") Mountain, on the border between China and North Korea, is the highest mountain (2750 m) in northeastern China. Recently, this mountain region has experienced a dramatic increase in air pollution, not only because of increasing volumes of tourism-derived traffic but also because of the long-range transport of polluted westerly winds passing through major industrial and urban cities in the eastern region of China. To assess the relative importance of the two sources of pollution, 16 polycyclic aromatic hydrocarbons (PAHs) as model substances were determined in the mountain soil. A total of 32 soil samples were collected from different sides of the mountain at different latitudes between July and August of 2009. The ∑PAH concentrations were within the range 38.5-190.1 ng g(-1) on the northern side, 117.7-443.6 ng g(-1) on the southern side, and 75.3-437.3 ng g(-1) on the western side. A progressive increase in the level of ∑PAHs with latitude was observed on the southern and western sides that face the westerly wind with abundant precipitation. However, a similar concentration gradient was not observed on the northern side that receives less rain and is on the leeward direction of the wind. The high-molecular-weight PAH compounds were predominant in the soils on the southern and western sides, while low-molecular-weight PAHs dominated the northern side soils. These findings show that the distribution of PAHs in the mountain soil is strongly influenced by the atmospheric long-range transport and cold trapping. Copyright © 2014 Elsevier Ltd.

Postural control is not a fully automatic process, but requires a certain level of attention, particularly as the difficulty of the postural task increases. This study aimed at testing whether experienced contemporary dancers, because of their specialized training involving the control of posture/balance, would present with a dual-task performance suggesting lesser attentional demands associated with dynamic postural control compared with non-dancers. Twenty dancers and 16 non-dancers performed a dynamic postural tracking task in both antero-posterior and side-to-side directions, while standing on a force platform. The postural task was performed, in turn, 1) as a stand-alone task, and concurrently with both 2) a simple reaction time task and 3) a choice reaction time task. Postural control performance was estimated through variables calculated from centre of pressure movements. Although no overall group difference was found in reaction time values, we found a better ability to control the side to side movements of the centre of pressure during the tracking task in dancers compared with non-dancers, which was dependent on the secondary task. This suggests that such increased ability is influenced by available attentional resources. PMID:28323843

Since topical anesthetics alone seldom provide adequate analgesia for laser resurfacing procedures, injectable forms of anesthesia are often required. However, their application is uncomfortable for the patient. In this study, it is investigated whether microneedle application would enhance the efficacy of topical anesthetics. Forty-seven patients participated in the study. Topical anesthetic agent EMLA was applied to the whole face of the patients. Microneedle treatment was applied to one side of the face with a roller-type device. Whole-face carbon dioxide laser resurfacing therapy was carried out then. The pain that patients experienced was assessed by using visual analog scale (VAS) method. VAS scores of two sides of the face were compared by using Wilcoxon signed-rank test. The mean of VAS score of the microneedle treated side was 2.1 ± 1.1 while that of the untreated side was 5.9 ± 0.9 and this difference was statistically significant (Wilcoxon signed-rank test, the Z-value is - 5.9683 and the p-value is < 0.001). This study revealed that microneedle application, with a roller-type device, is a safe and easy procedure in providing sufficient anesthesia for facial laser resurfacing without the need for supplementary nerve blocks or injections.

Advancements in nanotechnology sensors have aided in the detection of subtle, but significant cellular deviations that may mark certain stages of diseases. Gold nanorods (GNRs) are often studied for this purpose due to their tunable optical properties and ease in surface functionalization. The absorption properties of GNRs are governed by the localized surface plasmon resonance (LSPR), which strongly depends on the GNR's aspect ratio and on interparticle interactions. By controlling the coupling of nearby rods, a sensor can be created to respond to temperature fluctuations in the local environment. Here, we fabricated thermo-responsive gold nanorod assemblies by conjugating GNRs in end-to-end or side-by-side configurations using Poly(N-isopropyl acrylamide) (PNIPAM). End-to-end assemblies were fabricated through mixture of GNRs and PNIPAM in DI water. GNRs and PNIPAM were combined in DI water and dimethylformamide (DMF) under sonication to achieve side-by-side configuration. The optical absorption of the assemblies was measured by UV-Visible spectroscopy at different temperatures. As the temperature increased, the polymer contracted and initiated plasmon coupling between the GNRs. The optical spectrum experienced a blue- or red-shift for side-by-side or end-to-end configurations, respectively. Spectral tunability reversal was observed when cooled. Experimental results were verified by finite-difference time-domain (FDTD) calculations, which demonstrated spectral shifts under similar parameters. We present methods for fabrication of thermo-responsive gold nanorods for use as a local thermal nanosensor.

Explanations for side effect aversion in preventive medical treatment decisions

2008-01-01

Objective Many laypeople demonstrate excessive sensitivity to negative side effects of medical treatments, which may lead them to refuse beneficial therapies. This Internet-based experiment investigated three possible explanations for such “side effect aversion.” One was derived from mental accounting, one examined the mere presence of a side effect, and one focused on computational difficulties. Design Participants (N = 5,379) were presented with a hypothetical cancer preventive treatment situation that was or was not accompanied by one or two small side effects. The side effects were either beneficial or harmful. In all conditions the net absolute risk reduction associated with the treatment was 15%. Main Outcome Measures Participants indicated their willingness to accept treatment and their perceptions of the treatment’s effects on their overall cancer risk. Results Data were consistent only with the “mere presence” explanation of side effect aversion, the idea that side effects act as a strong negative cue that directly affects treatment appraisal. The number of negative side effects did not influence treatment willingness. Conclusion Side effect aversion is a challenge to informed decision making. Specific mechanisms that produce side effect aversion should be identified. PMID:19290712

Immune checkpoint inhibitors (ICPI), such as ipilimumab [anti-cytotoxic T-lymphocyte antigen-4 (CTLA-4) antibody] and nivolumab or pembrolizumab [anti-programmed cell death protein-1 (PD-1) antibodies], improve survival in several cancer types. Since inhibition of CTLA-4 or PD-1 leads to non-selective activation of the immune system, immune-related adverse events (irAEs) are frequent. Enterocolitis is a common irAE, currently managed with corticosteroids and, if necessary, anti-tumor necrosis factor-α therapy. Such a regimen carries a risk of serious side-effects including infections, and may potentially imply impaired antitumor effects. Vedolizumab is an anti-integrin α4β7 antibody with gut-specific immunosuppressive effects, approved for Crohn's disease and ulcerative colitis. We report a case series of seven patients with metastatic melanoma or lung cancer, treated with vedolizumab off-label for ipilimumab- or nivolumab-induced enterocolitis, from June 2014 through October 2016. Clinical, laboratory, endoscopic, and histologic data were analyzed. Patients initially received corticosteroids but were steroid-dependent and/or partially refractory. One patient was administered infliximab but was refractory. The median time from onset of enterocolitis to start of vedolizumab therapy was 79 days. Following vedolizumab therapy, all patients but one experienced steroid-free enterocolitis remission, with normalized fecal calprotectin. This was achieved after a median of 56 days from vedolizumab start, without any vedolizumab-related side-effects noted. The patient in whom vedolizumab was not successful, due to active ulcerative colitis, received vedolizumab prophylactically. This is the first case series to suggest that vedolizumab is an effective and well-tolerated therapeutic for steroid-dependent or partially refractory ICPI-induced enterocolitis. A larger prospective study to evaluate vedolizumab in this indication is warranted.

Systematic review. To assess the effectiveness of neuroreflexotherapy (NRT) for low back pain (LBP). Few of the alternatives for the management of LBP have a firm base of evidence for their effectiveness. Recently, a new intervention known as NRT has been developed in Spain and has been reported to have favorable results. Searches were undertaken according to Cochrane Collaboration guidelines, and randomized controlled trials that evaluated NRT as treatment for patients with nonspecific LBP were included. A qualitative synthesis and an assessment of methodological quality were undertaken. Three randomized controlled trials were included, with 125 and 148 subjects in control and intervention groups, respectively. NRT was compared with sham in two trials and standard care in one. Individuals receiving active NRT showed significantly better outcomes for pain, mobility, disability, medication use, consumption of resources, and costs. No major side effects were reported by those receiving active NRT. NRT appears to be a safe and effective intervention for nonspecific LBP. This conclusion is limited to three trials conducted by a small number of experienced clinicians. Further trials in other settings are needed to determine whether these favorable results can be generalized.

Side effects of prescribed and nonprescribed psychostimulant use are understudied. The study examined side effects of prescribed and nonprescribed psychostimulant use in a college sample with attention to possible gender differences. 2716 undergraduates (1448 male) between the ages of 17 and 57 years (M = 19.43 years, SD = 1.7 years) completed an online survey that included questions about the subjective side effects of prescribed and nonprescribed psychostimulant use. Results suggested that prescribed users more frequently reported side effects, compared to nonprescribed users. For prescribed users, females more frequently reported appetite, somatic, and anxiety-related side effects compared to males. For nonprescribed users, while females reported more somatic and anxiety-related side effects, males more frequently reported loss of sex drive and sweating as side effects. Conclusions/Importance: These findings suggest prescribed users of psychostimulants more frequently report side effects with prominent gender differences in line with gender roles.

Sexual side effects associated with conventional and atypical antipsychotics.

Compton, M T; Miller, A H

2001-01-01

The sexual side effects of psychotropic medications are becoming increasingly recognized in clinical psychiatry. The magnitude of the problem of sexual side effects associated with antipsychotic medications has yet to be fully elucidated, but a multitude of references in the literature demonstrate the importance of these side effects in both men and women. All currently used antipsychotic medications are associated with sexual side effects of various types. Although each antipsychotic medication may have a specific side effect profile determined by its various receptor affinities and by the degree to which it elevates serum prolactin, there is currently no evidence that specific side effects can be predicted. Sexual side effects can be categorized according to the phase of the sexual response cycle with which they interfere. Suggestions for clinical evaluation and treatment options are provided, including risk factor modification, dose reduction, switching agents, and addition of other agents. Sexual side effects associated with conventional and atypical antipsychotic medications represent an underestimated and understudied set of side effects that may diminish a patient's quality of life and lead to treatment noncompliance. Clinicians prescribing antipsychotic medications should be familiar with the classification, evaluation, and treatment of these side effects.

Background Up to 70% of patients receiving hematopoietic stem cell transplant develop oral mucositis as a side effect of high-dose melphalan conditioning chemotherapy. Oral cryotherapy has been documented to be potentially effective in reducing oral mucositis. The aim of this study was to examine the effectiveness of the cryotherapy protocol implemented within the hematopoietic stem cell transplant program. Methods A retrospective chart review was conducted of adult multiple myeloma patients who received high-dose melphalan conditioning therapy for autologous hematopoietic stem cell transplant. Primary endpoints were incidence and severity of oral mucositis. Secondary endpoints included duration of oral mucositis, duration of hospital stay, parenteral narcotics use and total parenteral nutrition use. Results One hundred and forty patients were included in the study, 70 patients in both no cryotherapy and cryotherapy groups. Both oral mucositis incidence and severity were found to be significantly lower in the cryotherapy group. Fifty (71.4%) experienced mucositis post cryotherapy compared to 67 (95.7%) in the no cryotherapy group (p < 0.001). The median oral mucositis severity, assessed using the WHO oral toxicity scale from grade 0-4, experienced in the no group was 2.5 vs. 2 in the cryotherapy group (p = 0.03). Oral mucositis duration and use of parenteral narcotics were also significantly reduced. Duration of hospital stay and use of parenteral nutrition were similar between the two groups. Conclusion The cryotherapy protocol resulted in a significantly lower incidence and severity of oral mucositis. These results provide evidence for the continued use of oral cryotherapy, an inexpensive and generally well-tolerated practice.

Side-to-side isoperistaltic strictureplasty (SSIS) is useful in patients undergoing surgery for Crohn disease (CD) to avoid wide small-bowel resections. To our knowledge, there are no definitive data regarding its recurrence risk factors. To evaluate the results obtained in a monocentric population of patients with CD who have undergone SSIS. From August 1996 to March 2010, 91 patients with CD underwent SSIS in our center. In this prospective observational study, side-to-side isoperistaltic strictureplasty was according the Michelassi technique in 69 patients and the Tonelli technique in 22 patients. Factors relating to the patient and the CD, surgery, and pharmacological therapy during the preoperative and perioperative periods were evaluated in association with medical or surgical recurrence. Side-to-side isoperistaltic strictureplasty. The recurrence-free curve was estimated using Kaplan-Meier analysis. Patients were stratified into cohorts in relation to the considered categorical variables and data were compared by using the Mantel-Cox log-rank test. Cox proportional hazard regression analysis was used to set up a predictive model simultaneously exploring the effects of all independent variables on a dichotomous outcome recurrence in relation to time. Among the 91 patients, the mean (SD) age was 39.5 (11.2) years and preoperative disease duration was 97.9 (85.8) months; 83 patients (91.2%) were followed up, of whom 37 (44.58%) experienced a recurrence at a mean (SD) of 55.46 (36.79) months after surgery (range, 9-140 months). The recurrence in the SSIS site at a mean (SD) of 48.25 (29.94) months after surgery affected 24 of 83 patients (28.9%), 9 being medical and 15 being surgical recurrence. Recurrence in the SSIS was statistically significantly associated with the time elapsed between diagnosis and surgery (P = .03). A borderline association between family history of CD and surgical recurrence (P = .054) was also found. Multivariate analysis identified the age at diagnosis (χ2 = 5.56; P = .02) and at surgery (χ2 = 7.77; P = .005), family history (χ2 = 6.26; P = .01), and smoking habit (χ2 = 10.06; P = .007) as independent risk factors for recurrence. In the short-term, SSIS leads to a resolution of symptoms in more than 90% of cases and the recurrence rate in the SSIS area is acceptable, even after long-term follow-up.

The scaly-sided merganser, Mergus squamatus, is considered one of the most threatened sea duck species in the Palearctic with limited breeding and wintering distribution in China and Russia. To provide information for future conservation efforts, we sequenced a portion of the mitochondrial (mt) DNA control region in four species of mergansers and three additional sea duck taxa to characterize the evolutionary history of the scaly-sided merganser, infer population trends that may have led to its limited geographic distribution, and to compare indices of genetic diversity among species of mergansers. Scaly-sided mergansers exhibit substantially lower levels of mtDNA genetic diversity (h = 0.292, π = 0.0007) than other closely related sea ducks and many other avian taxa. The four haplotypes observed differed by a single base pair suggesting that the species has not experienced a recent population decline but has instead been at a low population level for some time. A phylogenetic analysis placed the scaly-sided merganser basal to North American and European forms of the common merganser, M. merganser. Our inclusion of a small number of male samples doubled the number of mtDNA haplotypes observed, suggesting that additional genetic variation likely exists within the global population if there is immigration of males from unsampled breeding areas.

A sensor has a plurality of carbon nanotube (CNT)-based conductors operatively positioned on a substrate. The conductors are arranged side-by-side, such as in a substantially parallel relationship to one another. At least one pair of spaced-apart electrodes is coupled to opposing ends of the conductors. A portion of each of the conductors spanning between each pair of electrodes comprises a plurality of carbon nanotubes arranged end-to-end and substantially aligned along an axis. Because a direct correlation exists between the resistance of a carbon nanotube and its strain, changes experienced by the portion of the structure to which the sensor is coupled induce a corresponding change in the electrical properties of the conductors, thereby enabling detection of crack growth in the structure.

Opportunity, satisfaction and regret: trying long acting reversible contraception in a unique scientific circumstance.

Increased use of long-acting reversible contraception (LARC) can reduce unintended pregnancies. However, significant barriers exist to LARC uptake, particularly high up-front costs. In North Carolina in 2014, we interviewed 34 purposively-selected participants (aged 20-30 years) enrolled in a partially randomized patient preference trial to learn about their experiences with and attitudes toward contraception in this unique trial context. Cost of LARC was important in participants' decision-making. Experiencing an unintended pregnancy motivated women to switch to LARC. No participants who tried LARC, even those who experienced side effects, regretted it. Several participants regretted discontinuing their LARC. Concerns about insertion and removal did not influence future willingness to try LARC. Participants discussed the importance of affordability and feeling in control when choosing a contraceptive method. Cost, combined with uncertainty over whether LARC is the right method for them, may deter young women from trying LARC. Intrauterine devices and implants should be made affordable so that women can try them without significant financial commitment. Affordability will likely increase uptake, which will reduce unintended pregnancies. Regret from discontinuing LARC was more more frequently reported than regret from trying LARC. Providers should offer young women LARC and counsel to support continuation.

Background. Because of economic reasons, day surgery rates have steadily increased in many countries and the trend is to perform around 70% of all surgical procedures as day surgery. Literature shows that postoperative pain treatment remains unfulfilled in several fields such as orthopedic and general surgery patients. In Italy, the day surgery program is not yet under governmental authority and is managed regionally by local practices. Aim. To investigate the trends in pain intensity and its relation to type of surgeries and pain therapy protocols, in postoperative patients, discharged from three different Ambulatory Surgeries located in North West Italy (Piedmont region). Method. The present study enrolled 276 patients who undergone different surgical procedures in ambulatory regimen. Patients recorded postoperative pain score twice a day, compliance with prescribed drugs, and pain related reasons for contacting the hospital. Monitoring lasted for 7 days. Results. At discharge, 72% of patients were under weak opioids, 12% interrupted the treatment due to side effects, 17% of patients required extra drugs, and 15% contacted the hospital reporting pain problems. About 50% of patients experienced moderate pain during the first day after surgery. Results from our study show that most of the patients experienced avoidable pain after discharge. PMID:28115878

Background. Sugammadex offers a good alternative to the conventional decurarisation process currently performed with cholinesterase inhibitors. Sugammadex, which was developed specifically for the aminosteroid-structured rocuronium and vecuronium neuromuscular blockers, is a modified cyclodextrin made up of 8 glucose monomers arranged in a cylindrical shape. Methods. In this study, the goal was to investigate the efficacy of sugammadex. Sugammadex was used when there was insufficient decurarisation following neostigmine. This study was performed on 14 patients who experienced insufficient decurarisation (TOF <0.9) with neostigmine after general anaesthesia in the operating rooms of a university and a state hospital between June, 2012, and January, 2014. A dose of 2 mg/kg of sugammadex was administered. Results. Time elapsed until sugammadex administration following neostigmine 37 ± 6 min, following sugammadex it took 2.1 ± 0.9 min to reach TOF ≥0.9, and the extubation time was 3.2 ± 1.4 min. No statistically significant differences were detected in the hemodynamic parameters before and after sugammadex application. From the time of administration of sugammadex to the second postoperative hour, no side effects or complications occurred. None of the patients experienced acute respiratory failure or residual block during this time period. Conclusion. Sugammadex was successfully used to reverse rocuronium-induced neuromuscular block in patients where neostigmine was insufficient. PMID:25202709

Laryngeal electromyography (LEMG) is accepted as safe, with minimal side effects. However, patient hemodynamic stability, during these procedures, has not been reported. This study aimed to investigate the hemodynamics in patients undergoing LEMG and determine the risk factors for hemodynamic changes. We recruited 89 consecutive patients who underwent LEMG. Baseline and postprocedural changes in vital signs were analyzed. Diastolic blood pressure (DBP) increased from 75.08 ± 11.54 mmHg preprocedure to 77.4 ± 11.91 mmHg postprocedure (p = .006); pulse rate (PR) increased from 78.1 ± 13.3 beats per minute preprocedure to 80.02 ± 13.69 postprocedure (p = .027). Systolic blood pressure (SBP) and oxygen saturation were unchanged after the procedure. However, about 17% of patients experienced profound changes in vital signs of >20% above baseline during LEMG. The hemodynamic changes did not differ between sexes or between surgical and non-surgical etiologies of vocal fold paralysis. Two patients experienced profound but reversible near-syncope during the procedure. LEMG is a safe procedure with few immediate complications, though it may affect the patient's hemodynamic status by increasing DBP and PR. The hemodynamic monitoring is recommended so that timely intervention can be applied in case any warning sign occurs.

The picosecond Alexandrite laser has shown increased efficacy in tattoo removal in comparison to Q-switched lasers. However, bulla formation is a well-known and expected side effect of this novel treatment and causes patient discomfort. To analyze the incidence of bulla formation after tattoo treatment using the combination of the picosecond Alexandrite laser and fractionated CO2 ablation. This is a retrospective chart review to determine the incidence of bulla formation after laser tattoo removal in 95 patients who were treated with either with the picosecond Alexandrite laser alone or in combination with fractional CO2 ablation. Twenty-six patients (32%) treated with the picosecond laser alone experienced blistering, whereas none of the patients treated with the combination of the picosecond laser and fractionated CO2 ablation experienced blistering. The difference in incidence of bulla formation between the 2 groups was found to be statistically significant (p < .05). This study shows a significant decrease in bulla formation associated with tattoo treatment when fractionated CO2 ablation is added to the picosecond Alexandrite laser, which is consistent with observations from a previous case series. This is important because decreasing extensive blistering likely results in increased patient satisfaction and willingness to return for future treatments.

We conducted a descriptive study to identify the symptoms, emotional status, and quality of life experienced by hospitalized ovarian cancer patients undergoing chemotherapy, and influencing the factors of symptom clusters on their quality of life. A total of 192 patients who had been diagnosed with ovarian cancer and received adjuvant chemotherapy after surgery more than once from 2 university hospitals with over 800 beds located in the Seoul and Gyeonggi areas of South Korea were included in this study. Using a structured questionnaire, the symptoms, emotional status, and quality of life by these patients were investigated from May 2012 to June 2013. We identified the following 7 symptom clusters among ovarian cancer patients undergoing chemotherapy: psychological distress, fatigue-pain, abdominal discomfort, flu-like symptoms, fluid accumulation, and peripheral neuropathy. Patients with a high level of anxiety or depression experienced all symptoms at a higher level, and the 7 symptom clusters influenced all aspects of the patients' quality of life. This study provides to need interventions for the quality of life of ovarian cancer patients need to include the management of not only the physical symptoms and treatment-related side effects, but also the changes in their emotional status and daily lives.

Antiarrhythmic drugs are commonly prescribed cardiac drugs. Due to their receptor mimicry with several of the gastrointestinal tract receptors, they can frequently lead to gastrointestinal side effects. These side effects are the most common reasons for discontinuation of these drugs by the patients. Knowledge of these side effects is important for clinicians that manage antiarrhythmic drugs. This review focuses on the gastrointestinal side effects of these drugs and provides a detailed up-to-date literature review of the side effects of these drugs. The review provides case reports reported in the literature as well as possible mechanisms that lead to gastrointestinal side effects.

Medicinal gold has a well-known side effect profile that includes mucocutaneous eruptions. We describe three patients with a pruritic dermatitis that began after consumption of a gold-containing alcoholic beverage. Blood and urine gold levels, chemistry panels, hepatitis screens, skin biopsies, and patch tests were performed. The gold-containing liquor was analyzed for the presence and quantity of gold. The liquor consumed by all of the patients was a cinnamon schnapps with free-floating gold-colored flakes. Gold is present in the liquid portion of this liquor and in the solid flakes. Elevated levels of gold in the urine and blood were present in one patient 3 months after last drinking this beverage. Another patient had a positive patch test to gold sodium thiosulfate. All patients experienced improvement of their dermatitis after they stopped drinking the gold-containing liquor.

Extramammary Paget's disease is a rare cutaneous malignant neoplasm. Previous studies indicated the efficacy of docetaxel in advanced cases. The common side effects of docetaxel are usually tolerable and seldom life-threatening. We experienced a case of severe pseudomembranous colitis and neutropenic fever that developed just after the first cycle of docetaxel chemotherapy. To the best of our knowledge, there are few reports of pseudomembranous colitis associated with docetaxel administration for skin cancers. The patient showed complete resolution of her symptoms within 2 weeks with an oral metronidazole therapy. During the second and third cycles, the patient received docetaxel safely with lower doses. The present case indicated that pseudomembranous colitis should be included in the differential diagnosis when assessing patients who develop severe diarrhea during systemic chemotherapy with docetaxel.

Successful reintroduction of statin therapy after statin-associated rhabdomyolysis.

The case report demonstrates the successful use of an alternative statin after a statin-related episode of rhabdomyolysis. Statin-associated rhabdomyolysis is a serious adverse event with a very low incidence and is considered the most severe of the muscle-related side effects of the statins. Rechallenge with statins is not a recommended practice after rhabdomyolysis. The patient experienced a myocardial infarct 1 y after the episode of rhabdomyolysis. He used alternative lipid-lowering therapy for 2 y. His low-density lipoprotein cholesterol was not meeting typical secondary prevention targets. An alternative statin was introduced and the patient has been followed for 4 years without recurrence of the rhabdomyolysis. This case suggests it may be time to reconsider the accepted practice of permanently avoiding statin therapy after rhabdomyolysis. Copyright © 2015 National Lipid Association.

Modafinil: the unique properties of a new stimulant.

PubMed

Lyons, T J; French, J

1991-05-01

Modafinil, a novel stimulant which has several remarkable features that distinguish it from other stimulants, has been developed by Lafon, a French pharmaceutical company. Unlike the amphetamines, for example, modafinil is reported to have minimal peripheral side effects at therapeutic doses. It also appears to have a low abuse potential, does not interfere with normal sleep, and does not seem to produce tolerance. It improves vigilance especially in sleep-deprived subjects. It has been used clinically for up to 3 years in the treatment of narcolepsy and idiopathic hypersomnia. It could be an ideal replacement for amphetamine in short-term operations in which fatigue might threaten the successful completion of a mission. We recommend that military laboratories experienced in studying sustained performance include modafinil or perhaps a more selective alpha 1 receptor agonist in their investigations.

Dopamine agonists such as pramipexole are commonly used in the treatment of restless legs syndrome (RLS) as well as Parkinson's disease. Pramipexole's common side effects are well documented; however, adverse skin reactions are less well known. In this case, a 45-year-old male farmer presented with excessive daytime tiredness and reported a history suggestive of RLS. He was initiated on pramipexole but developed a maculopapular erythematous rash in sun-exposed areas 8 days after its commencement. The skin rash resolved following pramipexole's cessation and it is thought the patient experienced a drug-induced photosensitivity reaction to pramipexole. This case highlights the potential for photosensitivity reactions to pramipexole, which is especially significant in countries like Australia where UV solar radiation is especially high. © Royal College of Physicians 2018.

Familial hypercholesterolemia (FH) leads to premature coronary artery disease and aortic stenosis, with undertreated severe forms causing death at a young age. Lipoprotein apheresis (LA) is often required for lowering low-density lipoprotein cholesterol levels in severe FH. The objective of this study was to present the first experiences with LA in Malaysia, between 2004 and 2014. We retrospectively collected data from patient records to assess the effectiveness, adverse effects, patient quality of life, and costs associated with an LA service for genetically confirmed homozygous and heterozygous FH. We treated 13 women and 2 men aged 6 to 59 years, 10 with homozygous and 5 with heterozygous FH, all on maximally tolerated cholesterol-lowering drug therapy, for a total of 65 patient-years. Acute lowering of low-density lipoprotein cholesterol post apheresis was 56.3 ± 7.2%, with time-averaged mean lowering of 34.9 ± 13.9%. No patients experienced any cardiovascular events during the period of receiving LA. Patients receiving LA experienced few side effects and enjoyed reasonable quality of life, but inability to continue treatment was frequent because of cost. LA for severe FH can be delivered effectively in the short term in developing nations, but costs are a major barrier to sustaining this mode of treatment for this high-risk group of patients. New drug therapies for FH, such as the proprotein convertase subtilisin/kexin type 9 inhibitors, microsomal triglyceride transfer protein inhibitors, and apolipoprotein-B100 antisense oligonucleotides may allow improved care for these patients, but costs and long-term safety remain as issues to be addressed.

Background The inappropriate use of anabolic androgenic steroids (AAS) was originally a problem among athletes but AAS are now often used in nonsport situations and by patients attending regular addiction clinics. The aim of this study was to improve understanding of the development of multiple drug use in patients seeking treatment at an addiction clinic for AAS-related problems. Methods We interviewed six patients (four men and two women) with experience of AAS use who were attending an addiction clinic for what they believed were AAS-related problems. The patients were interviewed in-depth about their life stories, with special emphasis on social background, substance use, the development of total drug use and subjective experienced psychological and physical side effects. Results There was significant variation in the development of drug use in relation to social background, onset of drug use, relationship to AAS use and experience of AAS effects. All patients had initially experienced positive effects from AAS but, over time, the negative experiences had outweighed the positive effects. All patients were dedicated to excess training and took AAS in combination with gym training, indicating that the use of these drugs is closely related to this form of training. Use of multiple drugs was common either in parallel with AAS use or serially. Conclusion The study shows the importance of understanding how AAS use can develop either with or without the concomitant use of other drugs of abuse. The use of AAS can, however, progress to the use of other drugs. The study also indicates the importance of obtaining accurate, comprehensive information about the development of AAS use in designing treatment programmes and prevention strategies in this area.

Older adults often experience memory impairments, but can sometimes use selective processing and schematic support to remember important information. The current experiments investigate to what degree younger and healthy older adults remember medication side effects that were subjectively or objectively important to remember. Participants studied a list of common side effects, and rated how negative these effects were if they were to experience them, and were then given a free recall test. In Experiment 1, the severity of the side effects ranged from mild (e.g., itching) to severe (e.g., stroke), and in Experiment 2, certain side effects were indicated as critical to remember (i.e., “contact your doctor if you experience this”). There were no age differences in terms of free recall of the side effects, and older adults remembered more severe side effects relative to mild effects. However, older adults were less likely to recognize critical side effects on a later recognition test, relative to younger adults. The findings suggest that older adults can selectively remember medication side effects, but have difficulty identifying familiar but potentially critical side effects, and this has implications for monitoring medication use in older age.

2008-01-01

Chronic low back pain (CLBP) in older adults may be disabling and therapeutically challenging, largely because of the inefficacy and/or morbidity associated with traditional pain treatment. We conducted a randomized controlled trial in 200 men and women ≥ age 65 with CLBP to evaluate the efficacy of percutaneous electrical nerve stimulation (PENS) with and without general conditioning and aerobic exercise (GCAE), for reducing pain and improving physical function. Participants were randomized to receive 1) PENS, 2) control-PENS (brief electrical stimulation to control for treatment expectancy), 3) PENS + GCAE, or 4) control-PENS + GCAE, twice a week for 6 weeks. All four groups experienced significantly reduced pain (range −2.3 to −4.1 on the McGill Pain Questionnaire short form), improved self-reported disability (range −2.1 to −3.0 on Roland scale) and improved gait velocity (0.04–0.07 m/sec), sustained at 6 months. The GCAE groups experienced significantly fewer fear avoidance beliefs immediately post-intervention and at 6 months than non-GCAE groups. There were no significant side effects. Since brief electrical stimulation (i.e., control-PENS) facilitated comparably reduced pain and improved function at 6 months as compared with PENS, the exact dose of electrical stimulation required for analgesia cannot be determined. GCAE was more effective than PENS alone in reducing fear avoidance beliefs, but not in reducing pain or improving physical function. PMID:18930352

The tissue expansion process is done after mastectomies to increase the submuscular space in preparation for the placement of permanent breast implant. The process is often believed to be painful by patients who are often intimidated by the prospect of mechanically stretching out their skin and muscle. This study aims to quantify the pain experienced by patients and determine the different pain management techniques used. We used a case series approach, in which patients who were undergoing serial tissue expansion process were asked to rate their pain and anxiety on a scale from 1 to 10, using a questionnaire and the visual analog scale. Pain was rated during and after the expansion procedure, and patients were also surveyed to find the most commonly used and most effective pain management technique. Patients typically reported very little pain during and after the procedure, with an average of 0.4 to 2.5 pain experienced out of 10. The pain did not last, on average, longer than 1 day. Furthermore, the most widely used and most helpful pain medication was ibuprofen. During the tissue expansion procedure, the mean anxiety level was 0.64 (1.3). The findings show that tissue expansion process is a relatively low pain procedure and is not a contraindication for undergoing breast reconstruction. Ibuprofen, a mild treatment with few side effects, was efficacious in pain relief though most patients required no pain relief.

Road traffic accidents, injuries and deaths remain important public health problems in both developed and developing countries. These problems have since escalated with the introduction of the new phenomenon of commercial motorcycle transportation such as is found in the urbanizing slum of Nnewi, Anambra state of Nigeria. Using a semi-structured, interviewer-administered questionnaire, relevant data on socio-demographic and motorcycle characteristics were collected from a sample of 291 commercial motorcyclists selected by systematic sampling technique. Data on RTA, RTI and death were also collected from them overa period of three months. The result showed that young commercial motorcyclists {<30 years of age}, experienced higher fatal injury rate than older ones {> or =30 years of age}, {p < 0.01}. Motorcyclists with some formal education experienced RTA and RTI incidence rates that were significantly lower than those of motorcyclists with no formal education, {p < 0.01}. In the same vein, medical condition and social vices such as alcohol intake among the motorcyclists were found to be obvious predictors of RTA, RTI and death. Furthermore, motorcyclists who used >100 cc engine capacity motorcycles had significantly higher RTA incidence rate {478.8/100 MCY}, RTI rate {223.2/100 MCY} and FIR {410/100 MCY} than users of <100 cc engine motorcycles who recorded RTA incidence of 258.9/100 MCY, RTI rate of 49/100 MCY and zero fatal injury respectively {p < 0.01, p < 0.001, p < 0.001 respectively}. A careful consideration of all these predictors individually and collectively, will enable stakeholders in transport industry plan effective RTA, RTI and death control measures. Rather than an outright ban of motorcycle transportation, evening classes can be organized for the motorcyclists at subsidized rates to improve their literacy levels to run side by side with road safety informational lessons delivered at their places of work.

To determine the prevalence of and risk factors for avascular necrosis (AVN) in systemic lupus erythematosus (SLE). MEDLINE, CINAHL, Web of Science, EMBASE and Cochrane Library were searched from inception to July, 2015 and a random effects model was used to combine frequencies; study quality was assessed using STROBE. 2,041 citations identified 62 articles. Many results had high heterogeneity. The prevalence of symptomatic AVN was 9% (range 0.8%-33%) in SLE and 29% for asymptomatic AVN; femoral head was the most common location (8.0%). High-dose corticosteroids (CS) any CS use, maximum and cumulative dose, pulse therapy, and CS side-effects (hypertension, Cushings, but not diabetes mellitus or hyperlipidaemia) were associated with AVN, as was active SLE (cutaneous vasculitis, renal and neuropsychiatric manifestations, serositis, cytopenias) and Sjögren's, Raynaud's phenomenon, arthritis, cyclophosphamide (but not azathioprine mycophenolate mofetil, or methotrexate) and more damage (excluding musculoskeletal system). Antimalarial drugs were not protective. Rashes and oral ulcers were not associated with AVN. Mean daily dose of CS and duration of CS use had no impact on AVN occurence. Autoantibodies and other immunological markers did not predispose to AVN, except IgM anticardiolipin antibodies which doubled the risk. African Americans experienced more AVN (OR 1.8, p=0.04). AVN may occur in 1/3 of patients with SLE and 9% with symptoms. Features of active organ SLE (CNS, renal, cutaneous vasculitis, serositis, cytopenias) are associated with AVN as are CS, especially early in disease and at high doses. Those with early CS side-effects seem to have the highest risk of AVN.

Research about the support needs for and barriers to successful disease management of working adults with diabetes is limited. Our objective was to gain an in-depth understanding of how working adults in Hawaii perceive diabetes, barriers to disease management, and the services needed to keep people healthy and working. From November 2008 through March 2009, we conducted focus group interviews with 74 employed adults with diabetes enrolled in the Hawaii Demonstration to Maintain Independence and Employment project. Responses to questions were analyzed within and across groups to identify recurring themes. A third layer of analysis examined themes across responses to all questions, specifically, how barriers related to identified service needs. Employed participants with diabetes experienced pervasive effects on their lives as a result of the disease, although they interpreted these effects positively or negatively. Barriers to disease management, such as additional health issues, social prejudice, and lack of social support, indicated a need to educate the general public about the disease. Participants identified needing social support from other people with diabetes, psychological support to address the emotional side of diabetes, and coordinated teams of specialists to address medication side effects and other health-related barriers to disease management. Many participants discussed the challenge of integrating diabetes management with work and family responsibilities and the need for monetary support. This study provides insight into how employed adults perceived their disease and what they perceived as challenges to successfully managing diabetes. The findings provide future directions for community and workplace diabetes initiatives.

The aim of this project was to investigate adolescent perspectives on family planning services at a community-health center, with the intent to inform health center programs aimed at stemming the adolescent pregnancy rate. This project was cross-sectional and employed mixed methods, including surveys and interviews, for the purposes of quality improvement. The project was conducted in the obstetrics and gynecology clinic at an urban community health center in Boston. Twenty adolescent females (age 16-20) who used services at the health center. Participants were individually interviewed to assess perspectives on family planning services and to identify major influences on methods of pregnancy prevention. Major themes were categorized into contraceptive usage, reproductive health knowledge, adult influence and communication, barriers to contraceptive care and expectations of a family planning clinic. All participants were sexually active and 80% had experienced pregnancy. Reproductive health knowledge was variable and in many cases limited. Concern about disapproval was a prominent barrier to going to a clinician for contraception or advice and parents were not often involved in the initial contraception discussion. Other barriers to use of contraception included forgetting to use the methods and fear of side effects. We identified several potentially modifiable factors, including lack of knowledge, concern for provider disapproval and fear of side effects that may limit effective use of family planning services by adolescents. Further attention should be paid to these factors in designing and improving youth-friendly services in ob-gyn clinics.

The Impact of Virtual Reality on Chronic Pain

2016-01-01

The treatment of chronic pain could benefit from additional non-opioid interventions. Virtual reality (VR) has been shown to be effective in decreasing pain for procedural or acute pain but to date there have been few studies on its use in chronic pain. The present study was an investigation of the impact of a virtual reality application for chronic pain. Thirty (30) participants with various chronic pain conditions were offered a five-minute session using a virtual reality application called Cool! Participants were asked about their pain using a 0–10 visual analog scale rating before the VR session, during the session and immediately after the session. They were also asked about immersion into the VR world and about possible side effects. Pain was reduced from pre-session to post-session by 33%. Pain was reduced from pre-session during the VR session by 60%. These changes were both statistically significant at the p < .001 level. Three participants (10%) reported no change between pre and post pain ratings. Ten participants (33%) reported complete pain relief while doing the virtual reality session. All participants (100%) reported a decrease in pain to some degree between pre-session pain and during-session pain. The virtual reality experience was found here to provide a significant amount of pain relief. A head mounted display (HMD) was used with all subjects and no discomfort was experienced. Only one participant noted any side effects. VR seems to have promise as a non-opioid treatment for chronic pain and further investigation is warranted. PMID:27997539

Estimating cross-slope exchange from drifter tracks and from glider sections

NASA Astrophysics Data System (ADS)

Huthnance, John M.

2017-04-01

In areas of complex topography, it can be difficult to define "along-slope" or "cross-slope" direction, yet transport estimates are sensitive to these definitions, especially as along-slope flow is favoured by geostrophy. However, if drifter positions and hence underlying water depths are recorded regularly, we know where and when depth contours are crossed by the drifters, and hence by the water assuming that the drifters follow the water. An approach is discussed for deriving statistics of contour-crossing speed, via depth changes experienced by the drifters and an effective slope. The transport equation for (e.g.) salinity S can be reduced to an explicit equation for effective diffusivity K if we assume steady along-slope flow with known total transport Q, a salinity maximum at its "core" and effective diffusion to less saline waters to either side. Salinity gradients along the flow and to either side are needed to calculate K. Gliders provide a means of measuring salinity gradients in this context. Measurements at the continental shelf edge south-west of England and west of Scotland illustrate the calculation. Both approaches give overall rather than process-related estimates. There is limited scope for process discrimination according to (i) how often drifter locations are recorded and (ii) the time-intervals into which estimates are "binned". (i) Frequent recording may record more crossings owing to processes of short time scale, albeit these are less significant for slowly-evolving water contents. (ii) Sufficient samples for statistically significant estimates of exchange entail "bins" spanning some weeks or months for typically-limited numbers of drifters or gliders.

Menometrorrhagia and tachyarrhythmia after using oral and topical ginseng.

Widespread and uncontrolled use of ginseng has raised the question of its side effects and drug interactions. A 39-year-old female patient experienced menometrorrhagia. Her complaints had started 5 months earlier. The laboratory tests revealed follicle-stimulating hormone (FSH) and estradiol levels to be 10 mIU and 90 mIU, respectively. Endometrial biopsy was planned for the diagnosis of abnormal uterine bleeding. During the preoperative evaluation, the patient stated that she had been using both oral and topical ginseng for cosmetic reasons. The ECG revealed sinus tachycardia with occasional atrial premature beats. The procedure was postponed for 2 weeks so that the patient would stop taking ginseng, smoking, and drinking coffee. Arrhythmia stopped 10 days later. Tachycardia continued during the procedure but did not require treatment, as it did not cause any hemodynamic instability. An endometrial biopsy specimen showed a disordered proliferative pattern. The patient was advised to stop using oral and topical ginseng. During a follow-up visit, she had no sign of menometrorrhagia or tachyarrhythmia and her hemoglobin levels were in the normal range. Smoking and coffee consumption, along with ginseng use, can be responsible for arrhythmogenic effects. Abnormal uterine bleeding can cause tachycardia secondary to anemia. The clinical progress of this patient is consistent with our hypothesis that ginseng is responsible for menometrorrhagia, although this could be coincidental. Patients should always be asked prior to surgery if they use herbal medications, food supplements, or cosmetics as well as prescription drugs. This is of great importance for both diagnosis and avoidance of drug interactions and side effects during anesthesia.

Thanks to modern multimodal treatment the ouctome of patients with colorectal cancer has experienced significant improvements. As a downside, agent specific side effects have been observed such as sinusoidal obstruction syndrome (SOS) after oxaliplatin chemotherapy (OX). Bevazicumab targeting VEGF is nowadays comprehensively used in combination protocols with OX but its impact on hepatotoxicity is thus far elusive and focus of the present study. After MCT administration 67% of animals developed SOS. GOT serum concentration significantly increased in animals developing SOS ( p < 0.001). Subsequent to MCT administration 100% of animals treated with Anti-VEGF developed SOS. In contrast, animals receiving VEGF developed SOS merely in 40% while increasing the VEGF dose led to a further decrease in SOS development to 25%. MMP 9 concentration in animals developing SOS was significantly higher compared to controls ( p < 0,001). Additional treatment with Anti-VEGF increased the MMP 9 concentration significantly ( p < 0,05). Preservation of liver function is a central goal in both curative and palliative treatment phases of patients with CRC. Thus, knowledge about hepatotoxic side effects of chemotherapeutic and biological agents is crucial. From the results it can be concluded that Anti-VEGF exacerbates SOS paralleled by MMP 9 production. Therefore, OX-Bevacizumab combination therapies should be administered with caution, especially if liver parenchyma damage is apparent. Male Sprague-Dawley rats were gavaged Monocrotaline (MCT) to induce SOS. Recombinant VEGF or an Anti-VEGF antibody was administered to MCT-treated rats and the hepatotoxic effect monitored in defined time intervals. MMP 9 expression in the liver was measured by ELISA.

Toward the accurate first-principles prediction of ionization equilibria in proteins.

PubMed

Khandogin, Jana; Brooks, Charles L

2006-08-08

The calculation of pK(a) values for ionizable sites in proteins has been traditionally based on numerical solutions of the Poisson-Boltzmann equation carried out using a high-resolution protein structure. In this paper, we present a method based on continuous constant pH molecular dynamics (CPHMD) simulations, which allows the first-principles description of protein ionization equilibria. Our method utilizes an improved generalized Born implicit solvent model with an approximate Debye-Hückel screening function to account for salt effects and the replica-exchange (REX) protocol for enhanced conformational and protonation state sampling. The accuracy and robustness of the present method are demonstrated by 1 ns REX-CPHMD titration simulations of 10 proteins, which exhibit anomalously large pK(a) shifts for the carboxylate and histidine side chains. The experimental pK(a) values of these proteins are reliably reproduced with a root-mean-square error ranging from 0.6 unit for proteins containing few buried ionizable side chains to 1.0 unit or slightly higher for proteins containing ionizable side chains deeply buried in the core and experiencing strong charge-charge interactions. This unprecedented level of agreement with experimental benchmarks for the de novo calculation of pK(a) values suggests that the CPHMD method is maturing into a practical tool for the quantitative prediction of protein ionization equilibria, and this, in turn, opens a door to atomistic simulations of a wide variety of pH-coupled conformational phenomena in biological macromolecules such as protein folding or misfolding, aggregation, ligand binding, membrane interaction, and catalysis.

The desired (therapeutic) and undesired (side) effects of methylphenidate might have underlying correlations. The aim of this study was to explore the strength and the possible sources of these correlations. One hundred and fifty-seven children with ADHD (6-12 years) were administered placebo and methylphenidate (0.5 mg/kg in a divided b.i.d. dose), each for a one-week period, in a double-blind, crossover trial. Therapeutic response was assessed using the Conners' Global Index for parents (CGI-Parents) and teachers (CGI-Teachers), while side effects were assessed using the Barkley Side Effects Rating Scale (SERS). The side effect profile as assessed by the SERS was similar to that of previous studies with insomnia, decreased appetite, and headaches showing significant treatment effects (p < 0.005). These "somatic/physical" side effects did not correlate with CGI-Parents or CGI-Teachers. However, the side effects of "irritability", "proneness to crying", and "anxiousness" showed significant relationships with CGI-Parents. These "mood/anxiety" side effects showed no significant correlations with the CGI-Teachers. The greater "mood/anxiety" side effects on methylphenidate and placebo, the less the parents observe improvement of their children while treated with methylphenidate. This suggests that the correlations between "mood/anxiety" side effects and poor response to treatment may be driven by observer effects rather than biological commonalities between therapeutic and side effects of methylphenidate.

The thalamus has been a surgical target for the treatment of various movement disorders. Commonly used therapeutic modalities include ablative and nonablative procedures. A major clinical side effect of thalamic surgery is the appearance of speech problems. This review summarizes the data on the development of speech problems after thalamic surgery. A systematic review and meta-analysis was performed using nine databases, including Medline, Web of Science, and Cochrane Library. We also checked for articles by searching citing and cited articles. We retrieved studies between 1960 and September 2014. Of a total of 2,320 patients, 19.8% (confidence interval: 14.8-25.9) had speech difficulty after thalamotomy. Speech difficulty occurred in 15% (confidence interval: 9.8-22.2) of those treated with a unilaterally and 40.6% (confidence interval: 29.5-52.8) of those treated bilaterally. Speech impairment was noticed 2- to 3-fold more commonly after left-sided procedures (40.7% vs. 15.2%). Of the 572 patients that underwent DBS, 19.4% (confidence interval: 13.1-27.8) experienced speech difficulty. Subgroup analysis revealed that this complication occurs in 10.2% (confidence interval: 7.4-13.9) of patients treated unilaterally and 34.6% (confidence interval: 21.6-50.4) treated bilaterally. After thalamotomy, the risk was higher in Parkinson's patients compared to patients with essential tremor: 19.8% versus 4.5% in the unilateral group and 42.5% versus 13.9% in the bilateral group. After DBS, this rate was higher in essential tremor patients. Both lesioning and stimulation thalamic surgery produce adverse effects on speech. Left-sided and bilateral procedures are approximately 3-fold more likely to cause speech difficulty. This effect was higher after thalamotomy compared to DBS. In the thalamotomy group, the risk was higher in Parkinson's patients, whereas in the DBS group it was higher in patients with essential tremor. Understanding the pathophysiology of speech disturbance after thalamic procedures is a priority. © 2017 International Parkinson and Movement Disorder Society. © 2016 International Parkinson and Movement Disorder Society.

The World Health Organization estimates that 58% of pregnant women in developing countries are anemic. In spite of the fact that most ministries of health in developing countries have policies to provide pregnant women with iron in a supplement form, maternal anemia prevalence has not declined significantly where large-scale programs have been evaluated. During the period 1991-98, the MotherCare Project and its partners conducted qualitative research to determine the major barriers and facilitators of iron supplementation programs for pregnant women in eight developing countries. Research results were used to develop pilot program strategies and interventions to reduce maternal anemia. Across-region results were examined and some differences were found but the similarity in the way women view anemia and react to taking iron tablets was more striking than differences encountered by region, country or ethnic group. While women frequently recognize symptoms of anemia, they do not know the clinical term for anemia. Half of women in all countries consider these symptoms to be a priority health concern that requires action and half do not. Those women who visit prenatal health services are often familiar with iron supplements, but commonly do not know why they are prescribed. Contrary to the belief that women stop taking iron tablets mainly due to negative side effects, only about one-third of women reported that they experienced negative side effects in these studies. During iron supplementation trials in five of the countries, only about one-tenth of the women stopped taking the tablets due to side effects. The major barrier to effective supplementation programs is inadequate supply. Additional barriers include inadequate counseling and distribution of iron tablets, difficult access and poor utilization of prenatal health care services, beliefs against consuming medications during pregnancy, and in most countries, fears that taking too much iron may cause too much blood or a big baby, making delivery more difficult. Facilitators include women's recognition of improved physical well being with the alleviation of symptoms of anemia, particularly fatigue, a better appetite, increased appreciation of benefits for the fetus, and subsequent increased demand for prevention and treatment of iron deficiency and anemia.

Many of the world's population have hearing loss in one ear; current statistics indicate that up to 10% of the population may be affected. Although the detrimental impact of bilateral hearing loss, hearing aids, and cochlear implants upon music appreciation is well recognized, studies on the influence of single-sided deafness (SSD) are sparse. We sought to investigate whether a single-sided hearing loss can cause problems with music appreciation, despite normal hearing in the other ear. A tailored questionnaire was used to investigate music appreciation for those with SSD. We performed a retrospective survey of a population of 51 adults from a University Hospital Audiology Department SSD clinic. SSD was predominantly adult-onset sensorineural hearing loss, caused by a variety of etiologies. Analyses were performed to assess for statistical differences between groups, for example, comparing music appreciation before and after the onset of SSD, or before and after receiving hearing aid(s). Results demonstrated that a proportion of the population experienced significant changes to the way music sounded; music was found to sound more unnatural (75%), unpleasant (71%), and indistinct (81%) than before hearing loss. Music was reported to lack the perceptual qualities of stereo sound, and to be confounded by distortion effects and tinnitus. Such changes manifested in an altered music appreciation, with 44% of participants listening to music less often, 71% of participants enjoying music less, and 46% of participants reporting that music played a lesser role in their lives than pre-SSD. Negative effects surrounding social occasions with music were revealed, along with a strong preference for limiting background music. Hearing aids were not found to significantly ameliorate these effects. Results could be explained in part through considerations of psychoacoustic changes intrinsic to an asymmetric hearing loss and impaired auditory scene analysis. Given the prevalence of music and its capacity to influence an individual's well-being, results here present strong indications that the potential effects of SSD on music appreciation should be considered in a clinical context; an investigation into relevant rehabilitation techniques may prove valuable.

The plant Cannabis sativa has a long history of medical use in the treatment of pain and spasms, the promotion of sleep, and the suppression of nausea and vomiting. However, in the early 70s cannabis was classified in the Narcotic Acts in countries all over the world as having no therapeutic benefit; therefore, it cannot be prescribed by physicians or dispensed by pharmacists. In the light of this contradictory situation an increasing number of patients practices a self-prescription with cannabis products for relieving a variety of symptoms. An anonymous standardized survey of the medical use of cannabis and cannabis products of patients in Germany, Austria and Switzerland was conducted by the Association for Cannabis as Medicine (Cologne, Germany). During about one year 170 subjects participated in this survey; questionnaires of 128 patients could be included into the evaluation. 68% of these participants were males, 32% females, with a total mean age of 37.5 (+/- 9.6) years. The most frequently mentioned indications for medicinal cannabis use were depression (12.0%), multiple sclerosis (10.8%), HIV-infection (9.0%), migraine (6.6%), asthma (6.0%), back pain (5.4%), hepatitis C (4. 8%), sleeping disorders (4.8%), epilepsy (3.6%), spasticity (3.6%), headache (3.6%), alcoholism (3.0%), glaucoma (3.0%), nausea (3.0%), disk prolapse (2.4%), and spinal cord injury (2.4%). The majority of patients used natural cannabis products such as marihuana, hashish and an alcoholic tincture; in just 5 cases dronabinol (Marinol) was taken by prescription. About half of the 128 participants of the survey (52.4%) had used cannabis as a recreational drug before the onset of their illness. To date 14.3% took cannabis orally, 49.2% by inhalation and in 36.5% of cases both application modes were used. 72.2% of the patients stated the symptoms of their illness to have 'much improved' after cannabis ingestion, 23.4% stated to have 'slightly improved', 4.8% experienced 'no change' and 1.6% described that their symptoms got 'worse'. Being asked for the satisfaction with their therapeutic use of cannabis 60.8% stated to be 'very satisfied', 24.0% 'satisfied', 11.2% 'partly satisfied' and 4.0% were 'not satisfied'. 70.8% experienced no side effects, 26.4% described 'moderate' and 3.3% 'strong' side effects. 84.1% of patients have not felt any need for dose escalation during the last 3 months, 11.0% had to increase their cannabis dose 'moderately' and 4.8% 'strongly' in order to maintain the therapeutic effects. Thus, this survey demonstrates a successful use of cannabis products for the treatment of a multitude of various illnesses and symptoms. This use was usually accompanied only by slight and in general acceptable side effects. Because the patient group responding to this survey is presumably highly selected, no conclusions can be drawn about the quantity of wanted and unwanted effects of the medicinal use of the hemp plant for particular indications.

Ahmed, Rana; Borst, Jacqueline; Wei, Yong C; Aslani, Parisa

2017-01-01

The aim of the present study was to explore factors influencing parents' decisions to adhere and persist with ADHD pharmacotherapy in children. Focus groups ( n = 3) were conducted with 16 parents recruited from metropolitan Sydney. Group discussions explored factors impacting on treatment initiation, continuation, and cessation. Focus groups were audio-recorded, transcribed verbatim, and thematically content analyzed. Parents commenced and continued pharmacotherapy due to its positive impact on their child's behavior. Improvements in the child's academic performance and social interactions encouraged persistence with therapy. Parents elected to cease therapy after their children experienced side effects including appetite suppression, weight loss, and sleep disturbances. Concerns about long-term effects of ADHD medication use including potential for addiction and growth stunting, in addition to the stigma surrounding ADHD also contributed to parents ceasing treatment. The findings highlight a need for the provision of accurate information about ADHD and its treatments to parents to empower their treatment decisions and promote adherence.

The role of midazolam-induced sedation in bone marrow aspiration/trephine biopsies.

1996-12-01

This study was undertaken in 102 adult patients to evaluate the safety and efficacy of intravenous (i.v.) midazolam in the setting of bone marrow aspiration and trephine biopsy (BMAT). Combined local anaesthetic (LA) and sedation was used in 87% of patients and 13% received LA alone. Amnesia occurred in all sedated patients with only 9% experiencing a mild degree of post-procedure pain. This contrasted sharply with the non-sedated group, in whom 85% had intense pain during the biopsy followed by protracted local discomfort in approximately 54%. Drowsiness and some psychomotor impairment were the only notable sedation-related side-effects in approximately 20%. None required assisted ventilation. There was a resounding patient preference for BMAT with sedation. Considering the ease of use, safety and efficacy of i.v. midazolam, the availability of flumazenil as a reversal agent and the undoubted positive effects on quality of life, we would advocate using it in BMAT provided that there were no contraindications.

Methotrexate for the treatment of pediatric alopecia areata.

Landis, Erin T; Pichardo-Geisinger, Rita O

2018-03-01

Alopecia areata is a form of nonscarring hair loss that occurs in pediatric and adult patients, with presentation varying from round or ovoid patches of alopecia to alopecia totalis or universalis. While frustrating for patients, it can also be frustrating for clinicians to treat, as there is no definitive treatment. Dermatologists are very familiar with the use of methotrexate for psoriasis and other inflammatory skin diseases, and this medication is generally well tolerated in children. This study presents a case series reviewing the efficacy of methotrexate in our pediatric patients with alopecia areata, making use of a retrospective chart review design from 2011 to 2016. In this data set, 8/14 subjects (57%) experienced good regrowth with methotrexate, while 3/14 (21%) had a response that could not be assessed due to loss to follow-up or premature discontinuation of the medication. No cases discontinued the medication due to recognized methotrexate side effects. This review suggests methotrexate is a generally safe and often effective medication in pediatric alopecia areata.

Niche markets and evidence assessment in transition: a critical review of proposed drug reforms.

PubMed

Gibson, Shannon G; Lemmens, Trudo

2014-01-01

In response to rising demands and treatment costs, and the need to achieve better value for money in the face of tight fiscal constraints, both the National Health Service and the public drug reimbursement system are undergoing important reforms. Concurrently, the pharmaceutical sector itself is also alleged to be experiencing significant changes, perhaps most notably, a decline of the blockbuster model of drug development and a growing focus on niche market products. As pharmaceutical development strategies evolve and the resulting drug products become more complex, regulatory and policy responses must be able to evolve along with them. We explore how in numerous jurisdictions, including the UK, proposals for 'adaptive licensing' on the regulatory side and 'performance-based risk sharing agreements' on the funding side are shifting the focus of drug regulation and reimbursement towards more incremental access to new therapies and more post-market evidence generation. However, serious questions remain about how such reforms can be successfully implemented and whether they can balance demands for earlier access to promising new therapies with the need for robust evidence on safety, efficacy, and cost-effectiveness. © The Author 2014.

Effect of a novel low-energy pulsed-light device for home-use hair removal.

PubMed

Alster, Tina S; Tanzi, Elizabeth L

2009-03-01

Removal of unwanted hair is the most popular skin treatment worldwide. Over the past decade, various lasers and light sources for epilation have been advocated for use in an office setting, although most people continue to treat unwanted hair with a variety of temporary physical methods (e.g., waxing, shaving) in a home setting, presumably due to cost and convenience factors. To evaluate the safety and efficacy of a low-energy pulsed-light device intended for home-use hair removal. Twenty women (skin phototypes I-IV) with dark terminal hair in nonfacial sites (axilla, forearms, inguinal region, legs) self-administered three treatments at 2-week intervals using a handheld intense-pulsed-light device. Matched untreated skin sites were also studied. Hair counts and clinical photographs were obtained pretreatment and at 1, 3, and 6 months after the third treatment. Side effects and patient satisfaction scores were recorded. All patients showed a positive clinical response to treatment, with reduction of unwanted hair. No reduction of hair was noted in untreated matched areas. Hair counts were reduced 37.8% to 53.6% 6 months after the three treatments. Skin region influenced clinical response, with lower legs exhibiting greater hair reduction than arms and inguinal and axillary areas. Mild erythema was experienced in 25% of patients, but no other side effects or complications were encountered. Patient satisfaction scores were high, with all patients stating that they would purchase the device for future home use. CONCLUSIONS Low-energy pulsed light can be applied safely and effectively for at-home hair removal in a variety of nonfacial locations and skin phototypes I-IV.

BACKGROUND In IVF, Luteal phase support is usually performed using vaginal progesterone. A part of patients using this route reports being uncomfortable with this route. We tried to study whether the rectal route could be an effective alternative and associated with less discomfort. PATIENTS AND METHODS A prospective randomized controlled study. All patient were eligible for IVF treatment for infertility. After oocyte pickup, 186 patients were allocated to one the following protocols for luteal phase support: (i) rectal pessaries group: natural progesterone pessaries administered rectally 200 mg three times a day, (ii) vaginal pessaries group: natural progesterone pessaries administered vaginally 200 mg three times a day), and (iii) vaginal capsules group: natural micronized progesterone capsules administered vaginally 200 mg three times a day. On the day of pregnancy test, patients were asked to fill in a questionnaire conducted by an investigator in order to assess the tolerability and side effects of the LPS treatment taken. The primary endpoint was the occurrence of perineal irritation. RESULTS Fifty eight patients were assigned to the rectal pessaries group, 68 patients to the vaginal pessaries group, and 60 patients to the vaginal capsules group. All patients adhered to their allocated treatment. Implantation and clinical pregnancy rates per transfer did not differ between the three groups. Perineal irritation, which was our primary endpoint, was the same for all the three groups (respectively 1.7 % versus 5.9 % versus 11.7%). Regarding the other side effects, more patients experienced constipation and flatulence with the rectal route, whereas more patients reported vaginal discharge in the vaginal capsules group. CONCLUSION Rectal administration for luteal phase support is effective and well accepted alternative to vaginal route. PMID:28096703

To assess the efficacy and safety of combination therapy with clomiphene citrate (CC) and anastrozole (AZ) for male hypoandrogenism. We identified patients treated with a combination of CC + AZ in the period 2014 to 2017. Data were gathered on patient characteristics and laboratory values at baseline. Total testosterone, bioavailable testosterone, oestradiol and testosterone:oestradiol ratio were measured before combination therapy (treatment with CC only) and at CC + AZ combination therapy follow-ups. Treatment side effects were recorded; prostatic-specific antigen and haematocrit levels were measured to assess safety after 6 months. As a secondary outcome, semen characteristics were compared at baseline and after at least 3 months of combination therapy when these data were available. Data were analysed using a paired t-test and Wilcoxon's signed-rank test. A total of 51 men were included, with a mean age of 35.4 ± 7.4 years and a mean body mass index of 35.0 ± 8.0 kg/m 2 . After CC treatment, total testosterone, bioavailable testosterone, and oestradiol levels all significantly increased. AZ was added in all patients with hyperoestrogenaemia (oestradiol >50 pg/mL) or a testosterone:oestradiol ratio <10. CC + AZ therapy maintained therapeutic total testosterone and bioavailable testosterone levels while also normalizing oestradiol levels and testosterone:oestradiol ratio. Eleven patients experienced side effects: anxiety/irritability, n = 5; decreased libido, n = 4; elevated (>54%) haematocrit, n = 2. Combination therapy with CC + AZ is an effective and safe alternative for patients with elevated oestradiol level or low testosterone:oestradiol ratio. © 2018 The Authors BJU International © 2018 BJU International Published by John Wiley & Sons Ltd.

2001-06-01

The safety and pharmacokinetics of colistin were determined after first dose (n = 30) and again under steady-state conditions (n = 27) in 31 patients with cystic fibrosis receiving the drug as a component of their treatment for an acute pulmonary exacerbation of their disease. Patients ranged in age from 14 to 53 years and received colistin for 6 to 35 days. Each patient was started on colistin 5 to 7 mg/kg/day administered intravenously in three equally divided doses. Elimination half-life (t1/2), mean residence time (MRT), steady-state volume of distribution (Vdss), total body clearance (Cl), and renal clearance (Clr) after first-dose administration averaged 3.4 hours, 4.4 hours, 0.09 l/kg, and 0.35 and 0.24 ml/min/kg, respectively. No differences in colistin disposition characteristics between first-dose and steady-state evaluations were observed. Sputum sampling was incomplete and confounded by previous aerosol administration but revealed colistin concentrations that markedly exceeded observed plasma concentrations. Twenty-one patients experienced one or more side effects attributed to colistin administration. The most common reactions involved reversible neurologic manifestations, including oral and perioral paresthesias (n = 16), headache (n = 5), and lower limb weakness (n = 5). All of these apparent colistin-induced neurologic adverse effects, though bothersome, were benign and reversible. Intermittent proteinuria was observed on urinalysis in 14 patients, and 1 patient developed reversible, colistin-induced nephrotoxicity. No relationship between the occurrence of any colistin-associated adverse effect and plasma colistin concentration or colistin pharmacokinetic parameter estimate was observed. These data provide no basis for routine monitoring of colistin plasma concentrations to guide dosing for patient safety and suggest slow upward dose titration to minimize the incidence and severity of associated side effects.

to evaluate the correlations between perceived state anxiety during chemotherapy and quality of life in metastatic breast cancer patients. 62 metastatic breast cancer patients were evaluated during chemotherapy concerning age, living environment, marital status, social support and preexisting financial difficulties, the histological type of cancer, the site of the metastasis, the time from diagnosis, the type of surgical intervention, dexamethasone use, somatic comorbidities and the radiotherapy. The STAI-X1, BDI- IIA and the QLQ 30 (Quality of Life Questionnaire 30) plus BR 23 (Breast 23) questionnaires were applied. For the statistical analysis we used the SPSS 13 package. 24 subjects were experiencing low state anxiety (< or =39), whilst 38 had significant state anxiety (>39). Statistically significant differences were encountered between the two compared subgroups concerning the living environment, the type of surgical intervention, the marital status, the social support and the mean BDI scores, adjusted means were calculated for the items considered to potentially influence quality of life. Social, emotional and role functioning had lower scores in the low state anxiety group. Fatigue, future perspective, chemotherapy induced side effects, breast symptoms, upset by hair loss and sexual functioning were more disturbing in the high state anxiety group. The general health/quality of life mean score was lower in the low state anxiety group. Higher state anxiety correlates with certain quality of life items, suggesting that psychological counselling and appropriate therapy induced side effects management should be a priority in the palliative care for metastatic breast cancer patients.

Smokers were surveyed using a computer-assisted telephone interview to explore behaviors associated with the use of bupropion and nicotine-replacement therapies, using a convenient sample of Australian smokers. With assistance from the Pharmacy Guild of Australia, smokers were recruited through pharmacies and interviewed at baseline and after 3 months. A total of 508 smokers were recruited, 396 were interviewed at baseline and 318 completed a 3-month computer-assisted telephone interview. At 3 months, over two-thirds of participants were still smoking, the majority daily. However, the number of cigarettes smoked per week reduced and the time taken before smoking the first cigarette after waking increased. Nearly all participants started their medication (94%), while only 39% completed the full course. The main reasons for not completing the full course were adverse side effects, such as abnormal dreams and sleep disturbance. Despite Australian guidelines for bupropion and nicotine-replacement therapies to be used within a comprehensive treatment program, only 11% of patients were recommended behavioral support for nicotine dependence by their doctor or pharmacist. The results of the study shed light on patient utilization of the medication in terms of uptake and completion, possible side effects experienced and use of adjuncts. A better understanding of the use and experience of bupropion and nicotine-replacement therapies, and the lack of behavioral support offered with these, provides policy makers with a stronger evidence base to refine and improve the use of such pharmacotherapies.

Alteration of Duration Mismatch Negativity Induced by Transcranial Magnetic Stimulation Over the Left Parietal Lobe.

Mismatch negativity (MMN) is generated by a comparison between an incoming sound and the memory trace of preceding sounds stored in sensory memory without any attention to the sound. N100 (N1) is associated with the afferent response to sound onset and reflects early analysis of stimulus characteristics. MMN generators are present in the temporal and frontal lobe, and N1 generators are present in the temporal lobe. The parietal lobe is involved in MMN generation elicited by a change in duration. The anatomical network connecting these areas, lateralization, and the effect of the side of ear stimulation on MMN remain unknown. Thus, we studied the effects of low-frequency repetitive transcranial magnetic stimulation (rTMS) over the left parietal lobe on MMN and N1 in 10 healthy subjects. Low-frequency rTMS over the left parietal lobe decreased the amplitude of MMN following right ear sound stimulation, but the amplitude was unaffected with left ear sound stimulation. We observed no significant changes in the amplitude of N1 or the latency of MMN or N1. These results suggest that low-frequency rTMS over the left parietal lobe modulates the detection of early auditory changes in duration in healthy subjects. Stimulation that is contralateral to the side of the ear experiencing sound may affect the generation of duration MMN more than ipsilateral stimulation. © EEG and Clinical Neuroscience Society (ECNS) 2016.

The authors compared medication-induced mood switch risk (primary outcome), as well as treatment response and side effects (secondary outcomes) with three acute-phase treatments for bipolar II depression. In a 16-week, double-blind, multisite comparison study, 142 participants with bipolar II depression were randomly assigned to receive lithium monotherapy (N=49), sertraline monotherapy (N=45), or combination treatment with lithium and sertraline (N=48). At each visit, mood was assessed using standardized rating scales. Rates of switch were compared, as were rates of treatment response and the presence and severity of treatment-emergent side effects. Twenty participants (14%) experienced a switch during the study period (hypomania, N=17; severe hypomania, N=3). Switch rates did not differ among the three treatment groups, even after accounting for dropout. No patient had a manic switch or was hospitalized for a switch. Most switches occurred within the first 5 weeks of treatment. The treatment response rate for the overall sample was 62.7% (N=89), without significant differences between groups after accounting for dropout. The lithium/sertraline combination group had a significantly higher overall dropout rate than the monotherapy groups but did not have an accelerated time to response. Lithium monotherapy, sertraline monotherapy, and lithium/sertraline combination therapy were associated with similar switch and treatment response rates in participants with bipolar II depression. The dropout rate was higher in the lithium/sertraline combination treatment group, without any treatment acceleration advantage.

No studies have compared fractional microplasma radio frequency (RF) technology with the carbon dioxide fractional laser system (CO2 FS) in the treatment of atrophic acne scars in the same patient. To compare the efficacy and safety of fractional microplasma RF with CO2 FS in the treatment of atrophic acne scars. Thirty-three Asian patients received three sessions of a randomized split-face treatment of fractional microplasma RF or CO2 FS. Both modalities had a roughly equivalent effect. Échelle d'Évaluation Clinique Des Cicatrices d'Acné scores were significantly lower after fractional microplasma RF (from 51.1 ± 14.2 to 22.3 ± 8.6, 56.4% improvement) and CO2 FS (from 48.8 ± 15.1 to 19.9 ± 7.9, 59.2% improvement) treatments. There was no statistically significant difference between the two therapies. Twelve subjects (36.4%) experienced postinflammatory hyperpigmentation (PIH) after 30 of 99 treatment sessions (30.3%) on the CO2 FS side and no PIH was observed on the fractional microplasma RF sides. Both modalities have good effects on treating atrophic scars. PIH was not seen with the fractional microplasma RF, which might make it a better choice for patients with darker skin. © 2013 by the American Society for Dermatologic Surgery, Inc.

The use of electroconvulsive therapy (ECT) in children and adolescents is a controversial issue. This study was done to examine the pattern and practice as well as the outcome of electroconvulsive therapy administered to children and adolescents admitted to a tertiary care centre. A 10 year retrospective chart review of all children and adolescents (up to 16 years of age) admitted in the Child and Adolescent Psychiatry Centre, National Institute of Mental Health and Neurosciences (NIMHANS) who had received at least 1 session of ECT was done. Information regarding diagnosis, reasons for prescribing electroconvulsive therapy, details regarding the procedure and outcome variables was collected from the records. Clinical Global Impressions (CGI) scale rating of the severity of illness and improvement seen were done by 2 trained psychiatrists independently. 22 children and adolescents received electroconvulsive therapy over 10 years. There were an equal number of boys and girls. All received modified ECT. Most patients who received electroconvulsive therapy were severely ill. Catatonic symptoms 54.5% (12) were the most common reason for prescribing electroconvulsive therapy. It was efficacious in 77.3% (17) of the patients. Electroconvulsive therapy was relatively safe, and most experienced no acute side effects. 68.2% (15) who were on follow up and did not experience any long term side effects due to the electroconvulsive therapy. Electroconvulsive therapy has a place in the acute management of severe childhood psychiatric disorders. Further long term prospective studies are required. Copyright © 2014 Elsevier B.V.

Leukotriene receptor antagonists (LTRAs) are drugs which have been widely used more than ten years. As the use of LTRAs increases, our knowledge with respect to their side effects increases as well. The objective of our study was to evaluat the observed side effects of LTRAs used in patients with astma. 1024 patients treated only with LTRAs owing to asthma or early wheezing were included in the study for a five-year period. The observed side effects of LTRAs in these patients were retrospectively investigated. The side effects were divided into two parts as psychiatric and non-psychiatric. Among the 1024 cases included in the study, 67.5% of the patients out of 41 with side effects were male, 32.5% were female and the average age was 6.5 years. The rate of patients with asthma was 63.41% and 36.58% of the patients had early wheezing. It was determined that sex, age and diagnosis (early wheezing or asthma) of the patients were ineffective in the emergence of side effects. The average period for the emergence of side effects was the first month. It was observed that hyperactivity was the most frequently observed psychiatric side effect and that abdominal pain was the non-psychiatric side effect. The side effects of LTRAs were common in children. Therefore, patients must be informed at the beginning of the treatment and they must be evaluated at certain intervals.

The aim of the study was to compare the rate of sexual side effects of the selective serotonin reuptake inhibitor paroxetine versus the tricyclic antidepressant desipramine and to examine the effect of co-prescription of naltrexone on sexual side effects among participants in a randomized clinical trial. This was a secondary analysis (N = 88) of veterans who participated in a 12-week trial. All veterans were randomized into one of four treatment groups: (a) desipramine/naltrexone, (b) desipramine/placebo, (c) paroxetine/naltrexone, and (d) paroxetine/placebo. The main outcome measure was the frequency of sexual side effects consisting of "decreased sex drive" and/or "impotence" reported by veterans at each weekly visit. Approximately 61% of the veterans reported sexual side effects at least once during the trial, and 26.4% reported sexual side effects throughout the study. There were no significant differences in the frequency of sexual side effects among the four treatment groups. The results were similar when the comparison was made between the two antidepressant groups. There were no significant differences in the reporting of sexual side effects between those receiving desipramine and paroxetine. Also, the comparison between naltrexone and placebo did not alter the results. This is the first study to compare frequency of sexual side effect reporting between paroxetine and desipramine. We found no statistically significant differences in sexual side effect reporting between the two antidepressants. Also, the addition of naltrexone did not show any beneficial effect on the sexual side effect profile.

To compare the metabolic effects of acarbose and repaglinide in type 2 diabetic patients who are being treated with a sulphonylurea-metformin combination therapy. The primary endpoint of the study was to evaluate which add-on treatment between acarbose and repaglinide is more efficacious in reducing PPG. The second endpoint was to evaluate which of these two treatment is more efficacious in the global management of glucose homeostasis in the enrolled patients. After a 4-week run-in period with a sulphonylurea-metformin combination, 103 patients were randomised to receive in addition either repaglinide, up to 6 mg/day (2 mg three times a day) or acarbose, up to 300 mg/day (100 mg three times a day) with forced titration (independently of their glycaemic control, unless side-effects developed due to the drug dosage) for 15 weeks. The treatment was then crossed-over for further 12 weeks until the 27th week. We assessed body mass index (BMI), glycosylated haemoglobin (HbA(1c)), fasting plasma glucose (FPG), postprandial plasma glucose (PPG), fasting plasma insulin (FPI), postprandial plasma insulin (PPI), homeostatic model assessment (HOMA) index, systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and triglycerides (Tg), at baseline and at 1, 2, 15 and 27 weeks of treatment. Seven patients did not complete the study, comprising one patient who was lost to follow-up and a further six through side-effects (two in week 1, one in week 15 and three after cross-over) Side-effects were classified as nausea (one in acarbose group), gastrointestinal events (four in acarbose group), and hypoglycaemia (one in repaglinide group). After 15 weeks of therapy, the repaglinide-treated patients experienced a significant decrease in HbA(1c) (-1.1%, p < 0.05), FPG (-9.5%, p < 0.05), and PPG (-14.9%, p < 0.05), when compared to the baseline values. However, the same treatment was associated with a significant increase in body weight (+2.3%, p < 0.05), BMI (+3.3%, p < 0.05) and FPI (+22.5%, p < 0.05); The increase was reversed during the cross-over phase. After 15 weeks of therapy, the acarbose-treated patients experienced a significant decrease in body weight (-1.9%, p < 0.05), BMI (-4.1%, p < 0.05), HbA(1c) (-1.4%, p < 0.05), FPG (-10.7%, p < 0.05), PPG (-16.2%, p < 0.05), FPI (-16.1%, p < 0.05), PPI (-26.9%, p < 0.05), HOMA index (-30.1%, p < 0.05), when compared to the baseline values. All these changes were reversed during the cross-over study phase, except those relating to HbA(1c), FPG and PPG. The only changes that significantly differed when directly comparing acarbose- and repaglinide-treated patients were those relating to FPI (-16.1% vs. +22.5%, respectively, p < 0.05) and HOMA index (-30.1% vs. +2.7%, p < 0.05). In addition from having a similar effect to repaglinide on PPG, acarbose appeared to have a more comprehensive positive effect on glucose metabolism compared to repaglinide in this relatively small sample of type 2 diabetic patients when used as add-on therapy to sulphonylureas and metformin.

The effect of roof strength on reducing occupant injury in rollovers.

Roof crush occurs and potentially contributes to serious or fatal occupant injury in 26% of rollovers. It is likely that glazing retention is related to the degree of roof crush experienced in rollover accidents. Occupant ejection (including partial ejection) is the leading cause of death and injury in rollover accidents. In fatal passenger car accidents involving ejection, 34% were ejected through the side windows. Side window glass retention during a rollover is likely to significantly reduce occupant ejections. The inverted drop test methodology is a test procedure to evaluate the structural integrity of roofs under loadings similar to those seen in real world rollovers. Recent testing on many different vehicle types indicates that damage consistent with field rollover accidents can be achieved through inverted drop testing at very small drop heights. Drop test comparisons were performed on 16 pairs of vehicles representing a large spectrum of vehicle types. Each vehicle pair includes a production vehicle and a vehicle with a reinforced roof structure dropped under the same test conditions. This paper offers several examples of post-production reinforcements to roof structures that significantly increase the crush resistance of the roof as measured by inverted drop tests. These modifications were implemented with minimal impact on vehicle styling, interior space and visual clearances. The results of these modifications indicate that roof crush can be mitigated by nearly an order of magnitude, as roof crush was reduced by 44-91% with only a 1-2.3% increase in vehicle weight. Additionally, this paper analyzes the glazing breakage patterns in the moveable tempered side windows on the side adjacent to the vehicle impact point in the inverted drop tests. A comparison is made between the production vehicles and the reinforced vehicles in order to determine if the amount roof crush is related to glazing integrity in the side windows. Lastly, two drop test pairs, performed with Hybrid III test dummies, indicates that the reduction of roof crush resulted in a direct reduction in neck loading and therefore an increase in occupant protection.

Upper ocean response to the passage of two sequential typhoons

Two sequential typhoons, separated by five days, Chan-hom and Nangka in the summer of 2015, provided a unique opportunity to study the oceanic response and cold wake evolution. The upper ocean response to the passage of these two typhoons was investigated using multi-satellite, Argo float data and HYCOM global model output. The sea surface cooling (SSC) induced by Chan-hom was gradually enhanced along its track when the storm was intensified while moving over the ocean with shallow mixed layer. The location of maximum cooling of sea surface was determined by the storm's translation speed as well as pre-typhoon oceanic conditions. As a fast-moving storm, Chan-hom induced significant SSC on the right side of its track. Localized maximum cooling patches are found over a cyclonic eddy (CE). An analysis of data from Argo floats near the track of Chan-hom demonstrated that the mixed layer temperature (MLT) and mixed layer depth (MLD) had more variabilities on the right side than those on the left side of Chan-hom's track, while mixed layer salinity (MLS) response was different from those of MLT and MLD with an increase in salinity to the right side and a decrease in salinity to the left side of the track. Subsequently, because of the remnant effect of Chan-hom, the strong upwelling induced by Typhoon Nangka, the pre-existing CE as well as a slow translation speed (<2 m s-1) of the storm, the most significant SSC ( 6 °C) was observed over the CE region in the wake of the storm. Further, Nangka experienced a rapid weakening suggesting immediate negative feedback from the intensified SSC occurred in the CE region. After these two typhoons, the CE was enhanced and the sea surface height of eddy core was depressed by 10 cm. It took more than one month for SSC to restore to its pre-typhoon conditions, with the anomalous geostrophic current advection playing an important role in the process. The enhancement of chlorophyll-a concentrations was also noticed at both the CE region and close to Chan-hom's track.

A survey was conducted to compare the safety and effectiveness of labetalol and propranolol under routine conditions of clinical use. Patients received either labetalol (n = 805) or propranolol (n = 135) twice daily, according to package insert instructions, for six weeks. Every two weeks the patients were evaluated and weight, heart rate, blood pressure, dose, and adverse symptoms were recorded. Both treatment groups experienced a significant decline in blood pressure at six weeks; blood pressure decreased by 24/15 mmHg in the labetalol patients and by 20/14 mmHg in the propranolol patients. Heart rate decreased significantly in both groups, but the drop in the propranolol group was greater than in the labetalol group. Significantly more propranolol-treated patients reported fatigue (15.2% versus 6.3%), impotence (9.0% versus 3.2%), bad dreams (2.3% versus 0.3%), and cold extremities (2.3% versus 0%). Dizziness was reported more frequently by the labetalol group (9.1% versus 3.8%). Overall, both drugs were safe and effective in treating hypertension, but complaints of beta-blocker-associated side effects were more frequent with propranolol.

Hyperthermia is an established anti-cancer treatment but is limited by tolerance of adjacent normal tissues. Parenteral administration of gold nanorods (NRs) as a photosensitizer amplifies the effects of hyperthermia treatment while sparing normal tissues. This therapy is well tolerated and has demonstrated anti-tumor effects in mouse models. The purpose of this phase 1 study was to establish the safety and observe the anti-tumor impact of gold NR enhanced (plasmonic) photothermal therapy (PPTT) in client owned canine patients diagnosed with spontaneous neoplasia. Seven dogs underwent gold NR administration and subsequent NIR PPTT. Side effects were mild and limited to local reactions to NIR laser. All of the dogs enrolled in the study experienced stable disease, partial remission or complete remission. The overall response rate (ORR) was 28.6% with partial or complete remission of tumors at study end. PPTT utilizing gold nanorod therapy can be safely administered to canine patients. Further studies are needed to determine the true efficacy in a larger population of canine cancer patients and to and identify those patients most likely to benefit from this therapy.

Individual benefits of nestling begging: experimental evidence for an immediate effect, but no evidence for a delayed effect.

The evolutionary stability of honest signalling by offspring is thought to require that begging displays be costly, so the costs and benefits of begging--and whether they are experienced individually or by the whole brood--are crucial to understanding the evolution of begging behaviour. Begging is known to have immediate individual benefits (parents distribute more food to intensely begging individuals) and delayed brood benefits (parents increase provisioning rate to the brood), but the possibility of delayed individual benefits (previous begging affects the current distribution of food) has rarely, if ever, been researched. We did this using playback of great tit Parus major chick begging and a control sound from either side of the nest. Male parents fed chicks close to the speaker more when great tit chick begging, but not other stimuli, was played back. In contrast, there was no effect of playback at the previous visit on the chicks that male parents fed. We have thus demonstrated an immediate individual benefit to begging, but found no evidence of a delayed individual benefit in this species.

Family planning in the teen population.

As an increasing percentage of adolescents reach their sexual debut at younger ages, effective contraceptive methods, which will decrease the risks of unintended pregnancies and sexually transmitted diseases (STDs), become even more critical. Contraceptive methods which are less 'compliance-dependent', such as the implantable subdermal levonorgestrel and the injectable depot formulation of medroxyprogesterone acetate, are popular in adolescents but careful counseling before method selection and on-going counseling when side-effects are experienced are necessary and essential. The use of condoms to decrease the risks of STDs will continue to be important for adolescents, and it remains to be seen what impact the long-term methods will have on effective condom use. Adolescents' access to abortions when contraceptive methods fail, or when no method is used, is being challenged with state laws which mandate parental notification or permission. A greater knowledge about the option of emergency contraception could potentially lead to increased use of this method, particularly when the option of medications such as RU486 becomes available. The potential for a reduction in unintended pregnancies in adolescents, and a reduced need for abortions is a welcome prospect.

Side effects to antidepressant medication can affect the efficacy of treatment, but few predictors foretell who experiences side effects and which side effects they experience. This secondary data analysis examined whether depressed patients with comorbid panic disorder were more likely to experience side effects than those without panic disorder. The study also examined whether greater burden of side effects predicted a poorer treatment course for patients with panic disorder than those without panic disorder. To examine the specificity of these effects, analyses also examined 2 other anxiety disorders-social phobia and generalized anxiety disorder (GAD). Between 2002 and 2006, a large sample (N = 808) of chronically depressed individuals (assessed using the Structured Clinical Interview for DSM-IV-TR Axis I Disorders [SCID-IV]) received antidepressants according to a predetermined algorithm for 12 weeks. Every 2 weeks, depressive symptoms (per the Hamilton Depression Rating Scale) and side effects (specific side effects as well as several indicators of side effect burden) were assessed. Lifetime diagnosis of panic disorder (assessed using the SCID-IV) at baseline was associated with higher likelihood of gastrointestinal (OR = 1.6 [95% CI, 1.0-2.6]), cardiac (OR = 1.8 [95% CI, 1.1-3.1]), neurologic (OR = 2.6 [95% CI, 1.6-4.2]), and genitourinary side effects (OR = 3.0 [95% CI, 1.7-5.3]) during treatment. Increases in side effect frequency, intensity, and impairment over time were more strongly associated with increases in depressive symptoms for patients with panic disorder compared to those without panic disorder. Neither social phobia nor GAD was associated with these effects. Potentially due to heighte​ned interoceptive awareness of changes in their body, chronically depressed individuals with panic disorder may be at greater risk than those without panic disorder for antidepressant side effects and to experience a worsening of depressive symptoms as a result of these side effects over time.

"There is a chain of connections": using syndemics theory to understand HIV treatment side effects.

PubMed

Gagnon, Marilou

2018-03-12

Side effects are central to the experience of living longer with HIV but rarely have they been studied alone. Unlike other aspects of that experience, like quality of life, treatment adherence, chronicity, episodic disability, aging, health, and viral load suppression, side effects have not benefited from the same level of empirical and theoretical engagement from qualitative researchers. In this paper, we draw on syndemics theory and 50 qualitative interviews to better understand the experience of HIV treatment side effects. Two main categories were identified in the data: side effects as a product and side effects as a risk factor. The first category suggests that side effects are not just the product of taking antiretroviral drugs. They are also the product of particular conditions and tend to cluster with other health problems. The second category puts forward the idea that side effects can act as a syndemic risk factor by exposing PLWH to a greater risk of developing health problems and creating conditions in which psychosocial issues are more likely to emerge. The paper concludes by calling for more research on the complex nature of side effects and for the development of comprehensive approaches for the assessment and management of side effects.

Preliminary evaluation of a novel bone-conduction device for single-sided deafness.

A new intraoral bone-conduction device has advantages over existing bone-conduction devices for reducing the auditory deficits associated with single-sided deafness (SSD). Existing bone-conduction devices effectively mitigate auditory deficits from single-sided deafness but have suboptimal microphone locations, limited frequency range, and/or require invasive surgery. A new device has been designed to improve microphone placement (in the ear canal of the deaf ear), provide a wider frequency range, and eliminate surgery by delivering bone-conduction signals to the teeth via a removable oral appliance. Forces applied by the oral appliance were compared with forces typically experienced by the teeth from normal functions such as mastication or from other appliances. Tooth surface changes were measured on extracted teeth, and transducer temperature was measured under typical use conditions. Dynamic operating range, including gain, bandwidth, and maximum output limits, were determined from uncomfortable loudness levels and vibrotactile thresholds, and speech recognition scores were measured using normal-hearing subjects. Auditory performance in noise (Hearing in Noise Test) was measured in a limited sample of SSD subjects. Overall comfort, ease of insertion, and removal and visibility of the oral appliance in comparison with traditional hearing aids were measured using a rating scale. The oral appliance produces forces that are far below those experienced by the teeth from normal functions or conventional dental appliances. The bone-conduction signal level can be adjusted to prevent tactile perception yet provide sufficient gain and output at frequencies from 250 to 12,000 Hz. The device does not damage tooth surfaces nor produce heat, can be inserted and removed easily, and is as comfortable to wear as traditional hearing aids. The new microphone location has advantages for reducing the auditory deficits caused by SSD, including the potential to provide spatial cues introduced by reflections from the pinna, compared with microphone locations for existing devices. A new approach for SSD has been proposed that optimizes microphone location and delivers sound by bone conduction through a removable oral appliance. Measures in the laboratory using normal-hearing subjects indicate that the device provides useful gain and output for SSD patients, is comfortable, does not seem to have detrimental effects on oral function or oral health, and has several advantages over existing devices. Specifically, microphone placement is optimized for reducing the auditory deficit caused by SSD, frequency bandwidth is much greater, and the system does not require surgical placement. Auditory performance in a small sample of SSD subjects indicated a substantial advantage compared with not wearing the device. Future studies will involve performance measures on SSD patients wearing the device for longer periods.

[Aripiprazole, gambling disorder and compulsive sexuality].

Aripiprazole, an atypical or second-generation antipsychotic, is usually well tolerated. It is an approved treatment for schizophrenia and mania in bipolar disorder type 1. Unlike the other antipsychotics, it has high affinity agonist properties for dopamine D2 and D3 receptors. It has also 5-HT1A partial agonist and 5-HT2A antagonist properties. Aripiprazole is a first or second line treatment frequently used because it has reduced side effects such as weight gain, sleepiness, dyslipidemia, insulin resistance, hyperprolactinemia and extrapyramidal symptoms. We report the case of a 28-year-old male patient diagnosed with schizoid personality disorder. He was a moderate smoker with occasional social gambling habits. After several psychotic episodes, he was first treated with risperidone, but he experienced excessive sedation, decreased libido, erectile dysfunction and was switched to 15 mg aripiprazole. He developed an addiction habit for gambling at casino slot machines. Due to large gambling debts, he requested placement on a voluntary self-exclusion list. Thereafter, he turned his attention towards scratch card gambling. The patient described his experience of gambling as a "hypnotic state". He got several personal loans to obtain money to continue gambling. He was then referred to an addiction unit. Before being treated with aripiprazole, he was an exclusive heterosexual with a poor sexual activity. Under treatment, he switched to a homosexual behavior with hypersexuality, unprotected sex and sadomasochistic practices. The craving for gambling and compulsive sexual behavior ceased two weeks after aripiprazole was discontinued and he was switched to amisulpride. Thereafter, he reported a return to a heterosexual orientation. Compulsive behaviors such as gambling, hypersexuality and new sexual orientation are common in patients with Parkinson's disease treated with dopaminergic agonists. These behaviors involve the reward system, with an enhanced dopaminergic activity in the mesolimbic pathways and occur more frequently in young subjects, males with previous gambling habits and tobacco use. A few cases of aripiprazole-induced pathological gambling as well as aripiprazole-induced hypersexuality have been reported. To our knowledge, we are the first to report a case of gambling disorder associated with hypersexuality and change of sexuality orientation. Aripiprazole is the only antipsychotic with agonist properties for the D2 dopamine receptor. It may also act as an enhancer in the mesolimbic dopaminergic pathways. Aripiprazole also has 5-HT1A partial agonist and 5-HT2A antagonist properties that may promote sexual activity. Aripiprazole is an antipsychotic associated with reduced side effects compared to other antipsychotics. We report the case of a patient who experienced gambling disorder, hypersexuality and a new sexual orientation under treatment. These side effects are little known. They are usually difficult for patients to mention due to feelings of guilt. The consequences on social life, family and health may be serious. Clinicians and patients should be aware about the possible issue of these behavior disorders with aripiprazole. Copyright © 2016 L'Encéphale, Paris. Published by Elsevier Masson SAS.

Parecoxib sodium is the first parenteral COX-2 inhibitor used for pain management licensed for postoperative pain. However, no study has assessed the usage of parecoxib for acute traumatic pain in the emergency department (ED). The objective of this study was to investigate a potential alternative analgesic agent in the ED by determining the mean reduction of pain score between acute traumatic pain patients who were administered with intravenous (IV) parecoxib sodium versus IV morphine sulfate. The onset of perceptible analgesic effect and side effects were also evaluated. A randomized, double-blinded study comparing IV parecoxib 40 mg versus IV morphine at 0.10 mg/kg was conducted in adult patients presented with acute traumatic pain with numeric rating scale (NRS) of 6 or more within 6 hours of injury. Patients were randomized using a computer-generated randomization plan. Drug preparation and dispensing were performed by a pharmacist. Periodic assessment of blood pressure, pulse rate, oxygen saturation, and NRS were taken at 0, 5, 15, and 30 minute intervals after the administration of the study drug. The primary outcome was the reduction of NRS. Side effect and drug evaluation was conducted within 30 minutes of drug administration. There was no statistically significant difference in the reduction of mean NRS between patients in the IV parecoxib group or IV morphine group (P = 0.095). The mean NRS for patients treated with IV morphine were 7.1 at 0 minutes, 4.5 at 5 minutes, 3.1 at 15 minutes, and 2.0 at 30 minutes. Whereas mean NRS for patients who received IV parecoxib were 7.8 at 0 minutes, 5.7 at 5 minutes, 4.7 at 15 minutes, and 3.9 at 30 minutes. The onset of perceptible analgesic effects could be seen as early as 5 minutes. Dizziness was experienced in 42.9% of patients who received IV morphine compared to none in the parecoxib group. There was non-significant trend toward superiority of IV morphine over IV parecoxib. Looking at its effectiveness and the lack of opioid-related side-effects, the usage of IV parecoxib sodium may be extended further to a variety of cases in the ED.

Antipsychotic-associated side effects are well known and represent a significant treatment challenge. Still, few large studies have investigated the overall side effect burden of antipsychotics in real-life settings. To describe the occurrence of side effects and perceived burden of antipsychotics in a large naturalistic sample, taking polypharmacy and patient characteristics into account. Patients (n=1087) with psychotic disorders were assessed for side effects using the Udvalg for Kliniske Undersøgelser (UKU) side effect rating scale in addition to assessment of clinical and pharmacological data. Statistical analyses were performed controlling for possible confounding factors. Use of antipsychotics showed significant associations to neurologic and sexual symptoms, sedation and weight gain, and >75% of antipsychotics-users reported side effects. More side effects were observed in patients using several antipsychotics (p=0.002), with increasing total dose (p=0.021) and with antipsychotics in combinations with other psychotropic drugs. Patients and investigators evaluated the side effect burden differently, particularly related to severity, gender and antipsychotics dose. Twice as many females described side effect burden as severe (p=0.004). Patients with psychotic disorders have a high occurrence of symptoms associated with use of antipsychotics, and polypharmacy and female gender are seemingly risk factors for reporting a severe side effect burden. Due to the cross-sectional design evaluation of causality is tentative, and these findings should be further investigated in prospective studies. Copyright © 2017 Elsevier Inc. All rights reserved.

The inconsistency in clinician and patient ratings of clozapine-induced side effects underscore the need to supplement clinician-based estimates of side effects with patient-reported ones. The main aims of the study are validation of the Glasgow antipsychotic side-effects scale for clozapine (GASS-C) in Serbian inpatients/outpatients with schizophrenia or schizo-affective disorder and recommendations for its future use, based on common and rare clozapine-associated side-effects. The GASS-C was administered to 95 outpatients/inpatients diagnosed with schizophrenia, schizoaffective, or chronic psychotic disorder. The scale showed good overall reliability, with an internal consistency coefficient of α = 0.84, an average retest coefficient of rho = 0.76, and a Spearman-Brown coefficient of validity of 0.81. Side effects were absent or mild in 64.2% of the patients, moderate in 31.6%, severe in 4.2%; 14% of the subjects considered their symptoms distressing. The most commonly reported side-effects were drowsiness, thirst, frequent urination, and dry mouth. Women reported more side effects than men, and patients not in a relationship reported significantly fewer side effects than patients in a relationship. Results indicate a weak positive correlation (rho = 0.231; p = .025) between severity of side effects and clozapine dose. The GASS-C showed good psychometric characteristics in clinical population of patients on clozapine. In future studies, clozapine serum concentrations should be measured when using the GASS-C to monitor side effects.

Side effects play a key role in patients' failure to take antidepressants. There is evidence that verbal suggestions and informed consent elicit expectations that can in turn trigger the occurrence of side effects. Prior experience or learning mechanisms are also assumed to contribute to the development of side effects, although their role has not been thoroughly investigated. In this study, we examined whether an antidepressant's side effects can be learned via Pavlovian conditioning. Participants (n = 39) were randomly allocated to one of two groups and were exposed to a classical conditioning procedure. During acquisition, 19 participants received amitriptyline and 20 participants received a placebo pill. Pills were taken for four nights together with a novel-tasting drink. After a washout phase, both groups received a placebo pill together with the novel-tasting drink (evocation). Side effects were assessed via the Generic Assessment of Side Effects Scale prior to acquisition (baseline), after acquisition, and after evocation. A score of antidepressant-specific side effects was calculated. Participants taking amitriptyline reported significantly more antidepressant-specific side effects after acquisition compared to both baseline and the placebo group. After evocation, participants who underwent the conditioning procedure with amitriptyline reported significantly more antidepressant-specific side effects than those who never received amitriptyline, even though both groups received a placebo. Our results indicate that antidepressant side effects can be learned using a conditioning paradigm and evoked via a placebo pill when applied with the same contextual factors as the verum.

The Great Recession and Workers' Health Benefits.

During a recession, cost-sharing of employer-sponsored health benefits could increase to reduce labor costs in the U.S. Using a variation in the severity of recession shocks across industries, I find evidence that the enrollment rate of high deductible health plans (HDHPs) among workers covered by employer-sponsored health benefits increased more among firms in industries that experienced severe recession shocks. As potential mechanisms, I study employer-side and worker-side mechanisms. I find that employers changed health benefit offerings to force or incentivize workers to enroll in HDHPs. But I find little evidence of an increase in workers' demand for HDHPs due to a reduction in income. These results suggest that the HDHP enrollment rate increased during the Great Recession, as employers tried to save costs of offering health benefits. Copyright © 2018 Elsevier B.V.

A 72-year-old male patient underwent mobile-bearing posterior-stabilized total knee arthroplasty for osteoarthritis. He experienced a nontraumatic polyethylene tibial insert cone fracture 27 months after surgery. Scanning electron microscopy of the fracture surface of the tibial insert cone suggested progress of ductile breaking from the posterior toward the anterior of the cone due to repeated longitudinal bending stress, leading to fatigue breaking at the anterior side of the cone, followed by the tibial insert cone fracture at the anterior side of the cone, resulting in fracture at the base of the cone. This analysis shows the risk of tibial insert cone fracture due to longitudinal stress in mobile-bearing posterior-stabilized total knee arthroplasty in which an insert is designed to highly conform to the femoral component.

The main strategy adopted for Lymphatic Filariasis (LF) elimination globally is annual mass drug administration (MDA) for 4 to 6 rounds. At least 65% of the population at risk should be treated in each round for LF elimination to occur. In Kenya, MDA using diethylcarbamazine citrate (DEC) and albendazole data shows declining compliance (proportion of eligible populations who receive and swallow the drugs) levels (85%-62.8%). The present study's aim was to determine the role of personal opinions and experiences in compliance with MDA. This was a retrospective cross-sectional study conducted between January and September 2009 in two districts based on December 2008 MDA round. In each district, one location with high and one with low compliance was selected. Through systematic sampling, nine villages were selected and interviewer-based questionnaires administered to 965 household heads or adult representatives also systematically sampled. The qualitative data were generated from opinion leaders, LF patients with clinical signs and community drug distributors (CDDs) all purposively selected and interviewed. Sixteen focus group discussions (FGDs) were also conducted with single-sex adult and youth male and female groups. Chi square test was used to assess the statistical significance of differences in compliance with treatment based on the records reviewed. The house-to-house method of drug distribution influenced compliance. Over one-quarter (27%) in low compared to 15% in high compliance villages disliked this method. Problems related to size, number and taste of the drugs were more common in low (16.4%) than in high (14.4%) compliance villages. Reasons for failure to take the drugs were associated with compliance (p<0.001). The reasons given included: feeling that the drugs were not necessary, CDD not visiting to issue the drugs, being absent and thinking that the drugs were meant for only the patients with LF clinical signs. A dislike for modern medicine prevailed more in low (6.7%) than in high (1.2%) compliance villages. Experience of side effects influenced compliance (P<0.001). The common side effects experienced included giddiness, fever, headache and vomiting. Social support, alcohol and substance use were not associated with compliance in both types of villages (p>0.05). Community sensitization on treatment, drugs used, their regimen and distribution method involving all leaders should be strengthened by the Programme Implementers. The communities need to be made aware of the potential side effects of the drugs and that health personnel are on standby for the management of side effects in order to build confidence and increase the compliance levels.

Informing patients about treatment side effects increases the occurrence and intensity of side effects. Since the obligatory informed consent procedure in drug treatments requires transparency and nocebo research suggests that the informed consent of a drug leads to an increased occurrence of the mentioned side effects, the aim of this proof of concept study was to determine the effect of two different framings of informed consent on the occurrence, intensity, and perceived threat of side effects. Healthy male participants (n = 80) were randomized to one of two framing groups. The positive framing group was informed that the common side effect dizziness was a sign that the drug had started to work, while the neutral framing group was told that dizziness is an unpleasant but well-known side effect. Side effects were measured after the administration of metoprolol, an antihypertensive agent. Post hoc moderator analyses investigated the effect of pre-existing negative beliefs about the general harm of medication on the framing manipulation. Metoprolol-specific drug-attributed side effects were rated significantly less threatening in the positive framing group. The between-group effect size (Cohen's d) was small (d = 0.38, p = 0.049). Exploratory post hoc moderator analyses suggest that participants who believed that medication is a source of harmful effects benefited from positive framing, compared to neutral framing of drug-attributed side effects. Positive framing was partially effective in decreasing specific side effect measures, particularly among participants with a tendency to believe that medicine is harmful. Informed consent procedures should therefore be personalized, focusing on patients with negative treatment beliefs.
