Women who wish to assume full voice in their writing have no choice but to raise questions regarding their status and the status of creative writing within the academy. Tillie Olsen and Elaine Showalter have documented the bias in texts taught at the university in which women have little place, if at all. The effects are devastating: if the voices…
Ayurveda for chemo-radiotherapy induced side effects in cancer patients.
Metri, Kashinath; Bhargav, Hemant; Chowdhury, Praerna; Koka, Prasad S
2013-01-01
Chemotherapy drugs and radiotherapy are highly toxic and both damage adjacent healthy cells. Side effects may be acute (occurring within few weeks after therapy), intermediate or late (occurring months or years after the therapy). Some important side effects of chemotherapy are: nausea, vomiting, diarrhea, mucositis, alopecia, constipation etc; whereas radiation therapy though administered locally, can produce systemic side effects such as fatigue, anorexia, nausea, vomiting, alteration in the taste, sleep disturbance, headache, anemia, dry skin, constipation etc. Late complications of these therapies also include pharyngitis, esophagitis, laryngitis, persistent dysphagia, fatigue, hepatotoxicity, infertility and cognitive deficits. These arrays of side effects have a devastating effect on the quality of life of cancer survivors. Due to the inadequacy of most of the radio-protectors and chemo-protectors in controlling the side effects of conventional cancer therapy the complementary and alternative medicines have attracted the view of researchers and medical practitioners more recently. This review aims at providing a comprehensive management protocol of above mentioned chemo-radiotherapy induced side effects based on Ayurveda, which is an ancient system of traditional medicine practiced in Indian peninsula since 5000 BC. When the major side effects of chemo-radiotherapy are looked through an ayurvedic perspective, it appears that they are the manifestations of aggravated pitta dosha, especially under the group of disorders called Raktapitta (haemorrhage) or Raktadushti (vascular inflammation). Based on comprehensive review of ancient vedic literature and modern scientific evidences, ayurveda based interventions are put forth. This manuscript should help clinicians and people suffering from cancer to combat serious chemo-radiotherapy related side effects through simple but effective home-based ayurveda remedies. The remedies described are commonly available and safe. These simple ayurveda based solutions may act as an important adjuvant to chemo-radiotherapy and enhance the quality of life of cancer patients.
Ocular manifestations of drug and alcohol abuse
Peragallo, Jason; Biousse, Valérie; Newman, Nancy J.
2015-01-01
Purpose of review To review commonly encountered adverse ocular effects of illicit drug use. Recent findings Drug and alcohol abuse can produce a variety of ocular and neuro-ophthalmic side effects. Novel, so-called “designer,” drugs of abuse can lead to unusual ocular disorders. Legal substances, when used in manners for which they have not been prescribed, can also have devastating ophthalmic consequences. Summary In this review we will systematically evaluate each part of the visual pathways and discuss how individual drugs may affect them. PMID:24100364

Radiotherapy in NPC patients has side effects on the dentition, which affects quality of life dramatically. This case report presents multidisciplinary dental treatment approach in a 17-year-old male patient with a history of nasopharyngeal carcinoma (NPC), which was treated with chemotherapy and radiotherapy. The adolescent patient applied to dental hospital 4 years after the radiotherapy with aesthetic and functional problems on dentition affecting psychological, social, and physical aspects of his life. The dentition of the patient demonstrated the severe destruction as a devastating side effect of radiotherapy. With a successful multidisciplinary approach, our patient's aesthetics, function, and self-confidence were obtained. Well-established procedures, which include preventative care and maintenance, can reduce the duration and expenses of the treatment and help in challenging the life-long complications of radiotherapy.

A Rodent Model of Dynamic Facial Reanimation Using Functional Electrical Stimulation
Attiah, Mark A.; de Vries, Julius; Richardson, Andrew G.; Lucas, Timothy H.
2017-01-01
Facial paralysis can be a devastating condition, causing disfiguring facial droop, slurred speech, eye dryness, scarring and blindness. This study investigated the utility of closed-loop functional electric stimulation (FES) for reanimating paralyzed facial muscles in a quantitative rodent model. The right buccal and marginal mandibular branches of the rat facial nerve were transected for selective, unilateral paralysis of whisker muscles. Microwire electrodes were implanted bilaterally into the facial musculature for FES and electromyographic (EMG) recording. With the rats awake and head-fixed, whisker trajectories were tracked bilaterally with optical micrometers. First, the relationship between EMG and volitional whisker movement was quantified on the intact side of the face. Second, the effect of FES on whisker trajectories was quantified on the paralyzed side. Third, closed-loop experiments were performed in which the EMG signal on the intact side triggered FES on the paralyzed side to restore symmetric whisking. The results demonstrate a novel in vivo platform for developing control strategies for neuromuscular facial prostheses. PMID:28424583
Impulsive and Compulsive Behaviours in Parkinson's disease
Averbeck, BB; O’Sullivan, SS; Djamshidian, A
2014-01-01
Impulsive compulsive behaviours (ICBs) in Parkinson’s disease (PD) are a common and devastating side effect of dopamine replacement therapy. In this review we describe the phenomenology, prevalence and risk factors of these patients. Results of behavioural studies assessing the neuropsychological profile emphasize that the ICBs, which are behavioural addictions, are not hedonically motivated. Rather, other factors such as the inability to cope with uncertainty may be triggering ICBs. New insights from functional imaging studies, strengthening the incentive salience hypothesis are discussed and therapeutic guidelines for the management of ICBs in PD are given. PMID:24313567

Prevention of extravasation injuries secondary to doxorubicin.
Linder, R M; Upton, J
1985-03-01
Intravenously administered drugs with potentially devastating consequences should be given only by personnel highly knowledgeable regarding the side effects and skilled in intravenous cannulation. A strict protocol should be followed. The earliest signs heralding extravasation should be recognized and infusion discontinued immediately. If extravasation occurs, prompt surgical consultation is necessary. Injection into the volar wrist, dorsum of the hand, and antecubital fossa should always be avoided. Polyethylene catheters are preferable to butterfly needles for administering chemotherapeutic agents. A careful history of the venous problems of patients who require long-term therapy should be maintained in their chart. Ideally, vascular access should avoid these problems.

We report on the experience of a 23-member Australian medical team in Banda Aceh, Indonesia, following the 2004 Boxing Day tsunami. Arriving 13 days after the tsunami that devastated the city, killed 100,000 of its inhabitants and injured thousands more, we carried out 130 surgical procedures in austere conditions over a 12-day period. Most surgery was peripheral, principally for plastic surgical or orthopaedic procedures to lower limb injuries. Intravenous ketamine anaesthesia was the technique of choice, with good surgical conditions and few significant side-effects.

Dopaminergic agents are commonly used and effective treatments for restless legs syndrome (RLS), a disabling sensorimotor disorder. Less known are some of the potentially disabling side effects of these treatments, particularly iatrogenic gambling addiction, as is described here. Here the authors present a 62-year-old man, with a 20–year history of RLS, who developed gambling addiction while on dopaminergic treatment. He was not forewarned of this side effect, nor was he ever screened for gambling behaviours prior to or during treatment. Eight months after discontinuation of dopaminergic treatment and after 10 sessions of cognitive–behavioural therapy for gambling addiction, his gambling behaviours have partially resolved. To our knowledge, this is the first ever first person account of this condition. To prevent the devastating consequences of gambling addiction or to minimise its impact by early intervention, the authors call for clinicians involved in treatment of RLS to follow these simple measures: screen patients for gambling behaviours prior to the onset and during dopaminergic treatment; forewarn patients of this potential side effect; and if patients screen positive, refer them to specialist gambling treatment services, in addition to making necessary changes to their medication regime.

Pediatric uveitis: new and future treatments
Mehta, Preema J.; Alexander, Janet L.; Sen, H. Nida
2017-01-01
Purpose of review Pediatric uveitis is relatively uncommon, accounting for only 5–10% of all patients with uveitis. However, owing to high prevalence of complications and devastating outcomes, its lifetime burden can be significant. Recent findings Immunomodulatory therapy has been associated with better outcomes in noninfectious pediatric uveitis. However, effective treatments are limited by medication-related complications, including multiorgan toxicities and systemic side effects. Summary We review the current therapies available to treat pediatric uveitis, discuss novel and future therapies, and provide clinical recommendations utilizing these new agents. The consideration for treatment regimens in noninfectious pediatric uveitis is multifactorial. Understanding past, present, and future technology will aid in treatment of a complex and refractory disease. PMID:23872814
Update in the treatment of schizophrenia.
Katz, I; Kac, M
1993-04-01
The large number of drugs available to treat schizophrenia and the emergence of atypical and newer agents that provide efficiency with lessening of side effects may not only serve to provide more amelioration against this disease, but may also help us to unravel the neurochemical defects of the disorder. Despite these encouraging trends, the reality is that schizophrenia is still a devastating illness for a sizeable minority affected with the condition, that a 'cure' is not yet possible, and that drug therapies alone will not provide all that is required in acute or continuing management. Supporting care in the community for patient and family are just as important as pharmacotherapy in managing this problem.
Aloesin as a medical food ingredient for systemic oxidative stress of diabetes
Yimam, Mesfin; Brownell, Lidia; Jia, Qi
2015-01-01
Diabetes is a chronic disease that requires a long term management where oxidative stress plays a pivotal role in disease progression and intensifying secondary complications. In spite of all the research on diabetes and recent advances in diabetes treatments, the reality is that there is no cure for diabetes and its devastating complications. While currently available anti-diabetic therapies are effective in reducing blood glucose level, they are not without associated side effects when they are used for a long term applications. As a result, physicians and patients are inclining more towards to a safer therapy with less serious side effects in the form of medicinal foods and botanical alternatives that are suitable for chronic usage. Aloesin, an Aloe chromone, has previously been formulated with an aloe polysaccharide to give a composition called Loesyn, where it showed significant impact in reducing glycosylated hemoglobin, fasting blood glucose, fructosamine and plasma insulin level in humans. Radical scavenging activities of chromones and polysaccharides from Aloe have also been reported. Here we rationalize the relevance of use of Aloesin alone or in a standardized blend with Aloe polysaccharides, as a potential medical food to manage systemic oxidative stress and/or high blood glucose of diabetes.

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.

Cisplatin chemotherapy is used commonly to treat a variety of cancers despite severe side effects such as nausea, vomiting, and anorexia that compromise quality of life and limit treatment adherence. The neural mechanisms mediating these side effects remain elusive despite decades of clinical use. Recent data highlight the dorsal vagal complex (DVC), lateral parabrachial nucleus (lPBN), and central nucleus of the amygdala (CeA) as potential sites of action in mediating the side effects of cisplatin. Here, results from immunohistochemical studies in rats identified a population of cisplatin-activated DVC neurons that project to the lPBN and a population of cisplatin-activated lPBN calcitonin gene-related peptide (CGRP, a marker for glutamatergic neurons in the lPBN) neurons that project to the CeA, outlining a neuroanatomical circuit that is activated by cisplatin. CeA gene expressions of AMPA and NMDA glutamate receptor subunits were markedly increased after cisplatin treatment, suggesting that CeA glutamate receptor signaling plays a role in mediating cisplatin side effects. Consistent with gene expression results, behavioral/pharmacological data showed that CeA AMPA/kainate receptor blockade attenuates cisplatin-induced pica (a proxy for nausea/behavioral malaise in nonvomiting laboratory rodents) and that CeA NMDA receptor blockade attenuates cisplatin-induced anorexia and body weight loss in addition to pica, demonstrating that glutamate receptor signaling in the CeA is critical for the energy balance dysregulation caused by cisplatin treatment. Together, these data highlight a novel circuit and CGRP/glutamatergic mechanism through which cisplatin-induced malaise and energy balance dysregulation are mediated. SIGNIFICANCE STATEMENT To treat cancer effectively, patients must follow prescribed chemotherapy treatments without interruption, yet most cancer treatments produce side effects that devastate quality of life (e.g., nausea, vomiting, anorexia, weight loss). Although hundreds of thousands of patients undergo chemotherapies each year, the neural mechanisms mediating their side effects are unknown. The current data outline a neural circuit activated by cisplatin chemotherapy and demonstrate that glutamate signaling in the amygdala, arising from hindbrain projections, is required for the full expression of cisplatin-induced malaise, anorexia, and body weight loss. Together, these data help to characterize the neural circuits and neurotransmitters mediating chemotherapy-induced energy balance dysregulation, which will ultimately provide an opportunity for the development of well tolerated cancer and anti-emetic treatments.

Delayed epidural hematoma (DEH) following evacuation of traumatic acute subdural hematoma (ASDH) or acute epidural hematoma (EDH) is a rare but devastating complication, especially when it occurs sequentially in a single patient. A 19-year-old man who developed contralateral DEH following craniotomy for evacuation of a traumatic right-side ASDH and then developed a left-side DEH of the posterior cranial fossa after craniotomy for evacuation of the contralateral DEH. He was immediately returned to the operating room for additional surgeries and his neurological outcome was satisfactory. Although DEH occurring after evacuation of ASDH or acute EDH is a rare event, timely recognition is critical to prognosis.
Gene Therapy for Advanced Melanoma: Selective Targeting and Therapeutic Nucleic Acids
Viola, Joana R.; Rafael, Diana F.; Wagner, Ernst; Besch, Robert; Ogris, Manfred
2013-01-01
Despite recent advances, the treatment of malignant melanoma still results in the relapse of the disease, and second line treatment mostly fails due to the occurrence of resistance. A wide range of mutations are known to prevent effective treatment with chemotherapeutic drugs. Hence, approaches with biopharmaceuticals including proteins, like antibodies or cytokines, are applied. As an alternative, regimens with therapeutically active nucleic acids offer the possibility for highly selective cancer treatment whilst avoiding unwanted and toxic side effects. This paper gives a brief introduction into the mechanism of this devastating disease, discusses the shortcoming of current therapy approaches, and pinpoints anchor points which could be harnessed for therapeutic intervention with nucleic acids. We bring the delivery of nucleic acid nanopharmaceutics into perspective as a novel antimelanoma therapeutic approach and discuss the possibilities for melanoma specific targeting. The latest reports on preclinical and already clinical application of nucleic acids in melanoma are discussed. PMID:23634303
Military pain management in 21st century war.
Buckenmaier, Chester C; Griffith, Scott
2010-07-01
Morphine and other opioid drugs have played a major role in austere environment pain management since the Civil War, particularly in the military. While the pre-eminence and success of such medications is without question, their use is accompanied by significant side effects that are undesirable in the most advanced medical settings, and are potentially devastating in the field environment. Recently, there have been significant improvements in pain care for America's wounded service members, along with a shift in how many care providers view pain management. An increasing number of healthcare providers are seeing pain not merely as a symptom, but as a disease process. In addition to dramatically improving care for wounded service members, the evolution in the military's approach to pain is enhancing care for civilians.
Synthetic cannabinoids: the hidden side of Spice drugs.
Pintori, Nicholas; Loi, Barbara; Mereu, Maddalena
2017-09-01
Spice drugs are herbal mixtures sprayed with synthetic cannabinoids designed to mimic the psychoactive ingredient in marijuana [Δ-tetrahydrocannabinol (Δ-THC)] and synthesized by introducing modifications to the chemical structure of parental compounds aiming to circumvent legal regulations. Synthetic cannabinoid use/abuse can be devastating as toxicological effects and adverse reactions cannot be entirely predicted and may vary with the dose, route of administration, individual vulnerability and concomitant intake with other drugs. The absence of validated testing procedures in the clinical field makes difficult the adoption of a therapeutic approach effective in coping with the synthetic cannabinoid phenomenon, posing a significant challenge for prevention, treatment and public health in general. The aim of this review is to gain insights into the epidemiological, pharmacological and toxicological properties of synthetic cannabinoids, aiming to provide a reliable background needed for the management of synthetic cannabinoid-related adverse effects. Consumers, competent authorities and medical care professionals should be aware of the risks associated with synthetic cannabinoid use.

Abstract The devastating effect of West Nile virus (WNV) on the avifauna of North America has led zoo managers and conservationists to attempt to protect vulnerable species through vaccination. The Island Scrub-Jay (Aphelocoma insularis) is one such species, being a corvid with a highly restricted insular range. Herein, we used congeneric Western Scrub-Jays (Aphelocoma californica) to test the efficacy of three WNV vaccines in protecting jays from an experimental challenge with WNV: (1) the Fort Dodge West Nile-Innovator® DNA equine vaccine, (2) an experimental DNA plasmid vaccine, pCBWN, and (3) the Merial Recombitek® equine vaccine. Vaccine efficacy after challenge was compared with naïve and nonvaccinated positive controls and a group of naturally immune jays. Overall, vaccination lowered peak viremia compared with nonvaccinated positive controls, but some WNV-related pathology persisted and the viremia was sufficient to possibly infect susceptible vector mosquitoes. The Fort Dodge West Nile-Innovator DNA equine vaccine and the pCBWN vaccine provided humoral immune priming and limited side effects. Five of the six birds vaccinated with the Merial Recombitek vaccine, including a vaccinated, non-WNV challenged control, developed extensive necrotic lesions in the pectoral muscle at the vaccine inoculation sites, which were attributed to the Merial vaccine. In light of the well-documented devastating effects of high morbidity and mortality associated with WNV infection in corvids, vaccination of Island Scrub-Jays with either the Fort Dodge West Nile-Innovator DNA vaccine or the pCBWN vaccine may increase the numbers of birds that would survive an epizootic should WNV become established on Santa Cruz Island.

Achieving success with family planning in rural Afghanistan.
Huber, Douglas; Saeedi, Nika; Samadi, Abdul Khalil

Afghan women have one of the world's highest lifetime risks of maternal death. Years of conflict have devastated the country's health infrastructure. Total fertility was one of the world's highest, contraceptive use was low and there were no Afghan models of success for family planning. We worked closely with communities, providing information about the safety and non-harmful side-effects of contraceptives and improving access to injectable contraceptives, pills and condoms. Regular interaction with community leaders, mullahs (religious leaders), clinicians, community health workers and couples led to culturally acceptable innovations. A positive view of birth spacing was created by the messages that contraceptive use is 300 times safer than pregnancy in Afghanistan and that the Quran (the holy book of Islam) promotes two years of breastfeeding. Community health workers initiated the use of injectable contraceptives for the first time. The non-for-profit organization, Management Sciences for Health, Afghan nongovernmental organizations and the Ministry of Public Health implemented the Accelerating Contraceptive Use project in three rural areas with different ethnic populations. The contraceptive prevalence rate increased by 24-27% in 8 months in the project areas. Men supported modern contraceptives once they understood contraceptive safety, effectiveness and non-harmful side-effects. Injectable contraceptives contributed most to increases in contraceptive use. Community health workers can rapidly increase contraceptive use in rural areas when given responsibility and guidance. Project innovations were adopted as best practices for national scale-up.

The importance of mycobacteria as opportunistic pathogens, particularly members of the M. avium complex (MAC), in patients with progressive HIV infection was recognized early in the AIDS epidemic. It took longer to appreciate the global impact and devastation that would result from the deadly synergy that exists between HIV and M. tuberculosis. This HIV/M. tuberculosis co-pandemic is ongoing and claiming millions of lives every year. In addition to MAC, a number of other non-tuberculous mycobacteria have been recognized as opportunistic pathogens in HIV-infected individuals; some of these are more commonly encountered (e.g., M. kansasii) than others (M. haemophilum and M. genevense). Finally, there are challenges to concomitantly treating the HIV and the infecting Mycobacterium species, because of antimicrobial resistance, therapeutic side-effects and the complex pharmacologic interactions of the antiretroviral and antimycobacterial multidrug therapy.

Osteoporosis treatment: recent developments and ongoing challenges
Khosla, Sundeep; Hofbauer, Lorenz C
2018-01-01
Osteoporosis is an enormous and growing public health problem. Once considered an inevitable consequence of ageing, it is now eminently preventable and treatable. Ironically, despite tremendous therapeutic advances, there is an increasing treatment gap for patients at high fracture risk. In this Series paper, we trace the evolution of drug therapy for osteoporosis, which began in the 1940s with the demonstration by Fuller Albright that treatment with oestrogen could reverse the negative calcium balance that developed in women after menopause or oophorectomy. We note a watershed in osteoporosis drug discovery around the year 2000, when the approach to developing novel therapeutics shifted from one driven by discoveries in animal studies and clinical observations (eg, oestrogen, calcitonin, and teriparatide) or opportunistic repurposing of existing compounds (eg, bisphosphonates) to one driven by advances in fundamental bone biology (eg, denosumab) coupled with clues from patients with rare bone diseases (eg, romosozumab, odanacatib). Despite these remarkable advances, concerns about rare side-effects of anti-resorptive drugs, particularly bisphosphonates, and the absence of clear evidence in support of their long-term efficacy is leading many patients who could benefit from drug therapy to not take these drugs. As such, there remains an important clinical need to develop ways to enhance patient acceptance and compliance with these effective drugs, and to continue to develop new drugs that do not cause these side-effects and have prolonged anabolic effects on bone. Such changes could lead to a true reversal of this potentially devastating disease of ageing. PMID:28689769
Quinoline hybrids and their antiplasmodial and antimalarial activities.
Hu, Yuan-Qiang; Gao, Chuan; Zhang, Shu; Xu, Lei; Xu, Zhi; Feng, Lian-Shun; Wu, Xiang; Zhao, Feng
2017-10-20
Malaria, in particular infection with P. falciparum (the most lethal of the human malaria parasite species, responsible for nearly one million deaths every year), is one of the most devastating and common infectious disease throughout the world. Beginning with quinine, quinoline containing compounds have long been used in clinical treatment of malaria and remained the mainstays of chemotherapy against malaria. The emergence of P. falciparum strains resistant to almost all antimalarials prompted medicinal chemists and biologists to study their effective replacement with an alternative mechanism of action and new molecules. Combination with variety of quinolines and other active moieties may increase the antiplasmodial and antimalarial activities and reduce the side effects. Thus, hybridization is a very attractive strategy to develop novel antimalarials. This review aims to summarize the recent advances towards the discovery of antiplasmodial and antimalarial hybrids including quinoline skeleton to provide an insight for rational designs of more active and less toxic quinoline hybrids antimalarials.

Contraception for the older woman.
Glasier, A; Gebbie, A
1996-04-01
Contraception presents particular problems for women over the age of 40. Although fertility is declining and the risk of pregnancy may be small, the consequences of an unplanned pregnancy may be socially devastating and medically ill-advised. Menstrual dysfunction and psychosexual difficulties increase with age and may exacerbate the side-effects of some methods of contraception. The long-term risks of combined hormonal contraception, particularly cardiovascular disease, become more pertinent to women whose natural risk of disease increases with age. Patterns of sexual activity and contraceptive use change with age. The advantages and disadvantages of currently available methods of contraception are difficult to quantify, and the choice of method is very much a matter for individual concern. The increasing prevalence of HRT may complicate matters for some women who are unsure for how long to continue using contraception. Contraceptives of the future may be designed to improve the reproductive health of all women, particularly those approaching the menopause.

Warfare, genocide, and ethnic conflict: a Darwinian approach.
Dimijian, Gregory G
2010-07-01
As the 21st century dawns, I reflect on the history of humankind with growing concern about the need to understand the underlying biological and cultural roots of ethnic conflict and warfare. In the many studies of human conflict, innate biological predispositions have been neglected. This article is the third part of a series of seminars for medical residents at the University of Texas Southwestern Medical School at Dallas (see http://adarwinstudygroup.org/). The series starts with in-depth coverage of Darwinian natural and sexual selection, with examples from the domestication of animals and plants and the crisis of antibiotic resistance. The series strives to show how biology has been neglected in the study of the we-they orientation of human behavior, with its devastating consequences. The subject material is profoundly disturbing, as it looks at "human nature" and contrasts the "dark side" of human behavior with the opposite, profoundly caring and loving side.

We report the case of a 24-year-old female after sustaining a shotgun wound in the left upper extremity and chest. Initial emergency diagnostics revealed numerous shotgun pellets scattered throughout the left-side soft tissue, chest and upper lung lobe with one pellet having migrated into the left ventricle of the heart.Due to the devastating injury pattern, gunshot wounds are interdisciplinarily challenging and should include extended initial diagnostics, such as contrast agent CT. The potential toxicity of elevated lead blood levels have to be taken into further account.

The severe Dismounted Complex Blast Injury (DCBI) is characterized by high-energy injuries to the bilateral lower extremities (usually proximal transfemoral amputations) and/or upper extremity (usually involving the non-dominant side), in addition to open pelvic injuries, genitourinary, and abdominal trauma. Initial resuscitation and multidisciplinary surgical management appear to be the keys to survival. Definitive treatment follows general principals of open wound management and includes decontamination through aggressive and frequent debridement, hemorrhage control, viable tissue preservation, and appropriate timing of wound closure. These devastating injuries are associated with paradoxically favorable survival rates, but associated injuries and higher amputation levels lead to more difficult reconstructive challenges.
A role for ion channels in perivascular glioma invasion
Thompson, Emily G.
2017-01-01
Malignant gliomas are devastating tumors, frequently killing those diagnosed in little over a year. The profuse infiltration of glioma cells into healthy tissue surrounding the main tumor mass is one of the major obstacles limiting the improvement of patient survival. Migration along the abluminal side of blood vessels is one of the salient features of glioma cell invasion. Invading glioma cells are attracted to the vascular network, in part by the neuro-peptide bradykinin, where glioma cells actively modify the gliovascular interface and undergo volumetric alterations to navigate the confined space. Critical to these volume modifications is a proposed hydrodynamic model that involves the flux of ions in and out of the cell, followed by osmotically obligated water. Ion and water channels expressed by the glioma cell are essential in this model of invasion and make opportune therapeutic targets. Lastly, there is growing evidence that vascular-associated glioma cells are able to control the vascular tone, presumably to free up space for invasion and growth. The unique mechanisms that enable perivascular glioma invasion may offer critical targets for therapeutic intervention in this devastating disease. Indeed, a chloride channel-blocking peptide has already been successfully tested in human clinical trials. PMID:27424110
Prism adaptation and spatial neglect: the need for dose-finding studies.
Goedert, Kelly M; Zhang, Jeffrey Y; Barrett, A M
2015-01-01
Spatial neglect is a devastating disorder in 50-70% of right-brain stroke survivors, who have problems attending to, or making movements towards, left-sided stimuli, and experience a high risk of chronic dependence. Prism adaptation is a promising treatment for neglect that involves brief, daily visuo-motor training sessions while wearing optical prisms. Its benefits extend to functional behaviors such as dressing, with effects lasting 6 months or longer. Because one to two sessions of prism adaptation induce adaptive changes in both spatial-motor behavior (Fortis et al., 2011) and brain function (Saj et al., 2013), it is possible stroke patients may benefit from treatment periods shorter than the standard, intensive protocol of ten sessions over two weeks-a protocol that is impractical for either US inpatient or outpatient rehabilitation. Demonstrating the effectiveness of a lower dose will maximize the availability of neglect treatment. We present preliminary data suggesting that four to six sessions of prism treatment may induce a large treatment effect, maintained three to four weeks post-treatment. We call for a systematic, randomized clinical trial to establish the minimal effective dose suitable for stroke intervention.

Poor adherence to medication can have devastating consequences for patients with serious mental illness. The literature review and recommendations in this article are reprinted from The Expert Consensus Guideline Series: Adherence Problems in Patients with Serious and Persistent Mental Illness, published in 2009. The expert consensus survey (39 questions, 521 options) on adherence problems in schizophrenia and bipolar disorder was completed by 41 experts in 2008. This article first reviews the literature on interventions aimed at improving adherence. It then presents the experts' recommendations for targeting factors that can contribute to nonadherence and relates them to the literature. The following psychosocial/programmatic and pharmacologic interventions were rated first line for specific problems that can lead to nonadherence: ongoing symptom/ side-effect monitoring for persistent symptoms or side effects; services targeting logistic problems; medication monitoring/environmental supports (e.g., Cognitive Adaptation Training, assertive community treatment) for lack of routines or cognitive deficits; and adjusting the dose or switching to a different oral antipsychotic for persistent side effects (also high second-line for persistent symptoms). Among pharmacologic interventions, the experts gave high second-line ratings to switching to a long-acting antipsychotic when lack of insight, substance use, persistent symptoms, logistic problems, lack of routines, or lack of family/ social support interfere with adherence and to simplifying the treatment regimen when logistic problems, lack of routines, cognitive deficits, or lack of family/social support interfere with adherence. Psychosocial/programmatic interventions that received high second-line ratings in a number of situations included medication monitoring/environmental supports, patient psychoeducation, more frequent and/or longer visits if possible, cognitive behavioral therapy (CBT), family-focused therapy, and services targeting logistic problems. It is important to identify specific factors that may be contributing to a patient's adherence problems in order to customize interventions and to consider using a multifaceted approach since multiple problems may be involved.
Treating lupus in the kidney: where are we now, and where are we going?
Canetta, Pietro A A; Bomback, Andrew S; Radhakrishnan, Jai
2011-10-01
Kidney involvement is a frequent and dreaded consequence of systemic lupus erythematosus. While historically this condition was devastatingly morbid, over the past thirty years an improved understanding of the disease's pathobiology has accompanied increasingly effective treatment regimens that have dramatically improved the prognosis for affected patients. Induction and maintenance of remission can now be obtained in the majority of patients, although at least 20-30% may be refractory to treatment. What's more, the standard drugs in use for lupus nephritis remain fairly broad immunosuppressants, and carry notable risks and side effects. Recent years have witnessed an explosion in the number of novel immunomodulatory drugs being developed, with increasingly specific targets of action in the immune system. These molecules hold promise for a range of autoimmune disorders, including lupus nephritis, and several are already being actively investigated for that purpose. Here we review the current state of the art in the treatment of lupus nephritis, highlight the limits of standard treatments, and discuss the most promising of the novel therapies coming down the pipeline.
Outcomes after hand and upper extremity transplantation.
Shores, Jaimie T; Malek, Veronika; Lee, W P Andrew; Brandacher, Gerald
2017-05-01
Hand and upper extremity transplantation (HUET) has emerged as the most frequently performed reconstructive procedure in the burgeoning field of vascularized composite allotransplantation (VCA). VCA refers to a form of transplant with multiple tissue types that represents a viable treatment option for devastating injuries where conventional reconstruction would be unable to restore form and function. As hand transplantation becomes increasingly more common, discussions on advantages and disadvantages of the procedure seem to intensify. Despite encouraging functional outcomes, current immunosuppressive regimens with their deleterious side-effect profile remain a major concern for a life-changing but not life-saving type of transplant. In addition, a growing number of recipients with progressively longer follow-up prompt the need to investigate potential long-term sequelae, such as chronic rejection. This review will discuss the current state of HUET, summarizing outcome data on graft survival, motor and sensory function, as well as immunosuppressive treatment. The implications of these findings for VCA in terms of achievements and challenges ahead will then be discussed.
Current approaches to the management of idiopathic pulmonary fibrosis.
Raghu, Ganesh; Richeldi, Luca
2017-08-01
Idiopathic pulmonary fibrosis (IPF) is a progressive and ultimately fatal lung disease associated with dyspnoea, cough and impaired quality of life. Currently, the aims of patient care are to improve outcomes for patients by slowing the progression of the disease, extending life, and improving quality of life. A prompt, accurate diagnosis is important to enable patients to receive treatment early in the course of the disease and to be considered for lung transplantation. Two anti-fibrotic drugs, nintedanib and pirfenidone, have been shown to reduce decline in lung function in patients with IPF. In addition to pharmacological therapy, optimal management of IPF includes treatment of comorbidities, symptom relief, pulmonary rehabilitation, and palliative care. Patient education is important to enable patients to make decisions about their care and to help them manage their disease and the side-effects of anti-fibrotic drugs. Research continues into new treatments and combinations of treatments that may improve outcomes for patients with this devastating disease. Copyright © 2017. Published by Elsevier Ltd.

Androgenic-anabolic steroids are rarely used by sportsmen who want to improve physical performance in competition sport. Despite that they are well aware of the side effects of anabolic steroids, many young athletes in Bosnia and Herzegovina without competition motivation come in temptation, trying to achieve better muscle proportion and physical performance unknowing consequence of side effects and what is hiding behind. Risk factors such as increasing of lipid levels and arterial hypertension are major factors which have important role in the Pathogenesis of atherosclerosis and are responsible for occurrence of cardiovascular disease even causing a sudden death in young athletes. The aim of the study was to estimate the frequency of misusing of androgenic anabolic steroid drugs in young recreational sportsmen without competition motivation. This study will try to estimate vascular and lipid status, analyzing the side effects of steroids in young recreational athletes under the age of 35, in Bosnia and Herzegovina. The study included 70 individuals in period of 2010 till 2015 on recreational exercising program; 35 individuals misusing androgenic anabolic steroids during the period of 5 years were compared with 35 individuals which do not use androgenic anabolic steroids. Non-invasive methods were used in all individual (clinical examination and vascular ultrasound examination of vein system). The routine of training units in both groups was approximately two hours 4-6 times per week. Final analysis has reveal that in androgenic anabolic steroids group in 18 individuals or 55.7% arterial hypertension with hyperlipidemia was more represented, compared with the group without using anabolic steroids, represented by 2 individuals or 5.7% and it was statistically considered significant by using p value less than 0.05. (p<0.05). Statistically dominant population using anabolic steroids drugs are males (100%) or 35 individuals; we did not find females using anabolic steroids and that is why our research was limited to male population. Recreational male sportsmen are dominant androgenic anabolic steroids misusers, trying to achieve better muscle proportion and physical performance, they neglect the anabolic steroids side effects which have devastating consequence on vascular system. Benefits of misusing drugs in recreational exercising program in young sportsmen are mostly connected with development of arterial hypertension and hyperlipidemia and the variety of serious health disorders, progressing the pathogenesis of cardiovascular disease.

Intramedullary spinal cord abscess (ISCA) in children is extremely a rare infection of the central nervous system (CNS); and probably a devastating neurological condition. Clinical awareness of patients at risk is crucial for early diagnosis and intervention; as this entity is one of the treatable conditions of paraparesis. Association with congenital neuro-ectodermal abnormality in children is frequent. This pathology highlights the importance of complete neurological checks of infants as a part of their routine physical examination and early management of patients with congenital dermal sinus, prophylactic surgical resection of such a congenital anomaly is recommended by most authors to prevent serious infections of the CNS. However, once the abscess is established; immediate surgical drainage along side adequate antibiotics should be instituted. This may guarantee improving neurological outcome. In this communication, the authors present their experience with four cases of ISCA in children treated successfully with surgical drainage, intravenous antibiotics and neuro rehabilitation between 2001 and 2006 and discuss their results. We concluded that early diagnosis and treatment is essential; before a devastating mechanico-vascular insult of the spinal cord is established from rapid formation of the abscess and a swift expansion of the spinal cord within the limited intraspinal space.

Although the vast majority of earthquakes in the State of Hawaii are closely related to the active volcanism associated with the southeastern part of the Island of Hawai‘i, the October 2006 Kīholo Bay and Māhukona earthquakes clearly suggest the devastating potential of deeper lithospheric earthquakes. Large earthquakes thought to be nearly M7 have struck near the islands of Lāna‘i (1871) and Maui (1938). It is thought that these, like the 2006 earthquakes, were deep lithospheric flexure earthquakes (Wyss and Koyanagi, 1992; Klein and others, 2001). Thus, it is important to recognize the potential seismic hazard posed by such earthquakes beneath the older Hawaiian Islands. The data and observations afforded by the 2006 earthquakes promise to improve probabilistic seismic hazards modeling in Hawai‘i. The effects of the October 15, 2006, Kīholo Bay-Māhukona earthquakes are shown in images taken from the coastal route along the northern half of the Island of Hawai‘i, where damage was the most concentrated. The direction of presentation is counter-clockwise, from Pa‘auilo on the eastern or windward (Hāmākua) side to Kealakekua Bay on the western or leeward (Kona) side. A list of sites, their locations, coordinates, and distance from the epicenter at Kīholo Bay are given in table 1. A Google Earth map (fig. 7) and a topographic map (fig. 8) pinpoint the 36 sites where damage was documented and digital images were compiled for this collection.

Several flood disasters occur every year all over the world, mostly due to levee and dam failure which result in human fatalities as well as devastating economic damages. To model and predict earthen embankment failures for the preparation of emergency action plans and risk assessments, the soil erodibility by flowing water is an essential parameter. The determination of erodibility becomes even more complicated for cohesive soils because of the large number of parameters controlling their erosion behavior (e.g. clay content, plasticity, compaction effort, compaction water content) and the difficulty of estimating these parameters. In this study the effect of the compaction energy and compaction water content on the erodibility of a sandy loam soil was assessed. Soil samples were prepared in a standard diameter compaction mold, 101.6 mm, for three levels of compaction effort and water content (i.e. low, medium, and high) with two replications for each case (18 tests total) and examined using the jet erosion test (JET). Observations from qualitative and statistical analyses of the data are: 1) a wide range of erodibility, from very erodible to very resistant, was produced by changes in the compaction characteristics; 2) for a given compaction energy, the erosion resistance based on the detachment rate coefficient kd tends to become minimum near the optimum compaction water content. On the dry side of optimum compaction water content, kd decreases with steep gradients by increasing the water content, while it increases with a flatter gradient on the wet side; 3) At a given water content, the soil erosion resistance increases with compaction efforts; 4) compaction water content influences soil erosibility more than compaction energy, especially on the dry side of the optimum compaction water content; and 5) for a given compaction effort, the critical shear stress increases with water content up to an optimum water content and then it decreases which is in consistent with the kd trends.

Stroke is a devastating disease and a leading cause of death and disability. Currently, the only FDA approved therapy for acute ischemic stroke is the intravenous administration of the thrombolytic medication, recombinant tissue plasminogen activator (tPA). However, this treatment has many contraindications and can have dangerous side effects such as intra-cerebral hemorrhage. These treatment limitations have led to much interest in potential adjunctive therapies, such as therapeutic hypothermia (T <= 35 °C) and ultrasound enhanced thrombolysis. Such interest may lead to combining these therapies with tPA to treat stroke, however little is known about the effects of temperature on the thrombolytic efficacy of tPA. In this work, we measure the temperature dependence of the fractional clot mass loss Δm(T) resulting from tPA exposure in an in vitro human clot model. We find that the temperature dependence is well described by an Arrhenius temperature dependence with an effective activation energy Eeff of 42.0 ± 0.9 kJ mole-1. Eeff approximates the activation energy of the plasminogen-to-plasmin reaction of 48.9 kJ mole-1. A model to explain this temperature dependence is proposed. These results will be useful in predicting the effects of temperature in future lytic therapies.
Mouse Models of Type 2 Diabetes Mellitus in Drug Discovery.
Baribault, Helene
2016-01-01
Type 2 diabetes is a fast-growing epidemic in industrialized countries, associated with obesity, lack of physical exercise, aging, family history, and ethnic background. Diagnostic criteria are elevated fasting or postprandial blood glucose levels, a consequence of insulin resistance. Early intervention can help patients to revert the progression of the disease together with lifestyle changes or monotherapy. Systemic glucose toxicity can have devastating effects leading to pancreatic beta cell failure, blindness, nephropathy, and neuropathy, progressing to limb ulceration or even amputation. Existing treatments have numerous side effects and demonstrate variability in individual patient responsiveness. However, several emerging areas of discovery research are showing promises with the development of novel classes of antidiabetic drugs.The mouse has proven to be a reliable model for discovering and validating new treatments for type 2 diabetes mellitus. We review here commonly used methods to measure endpoints relevant to glucose metabolism which show good translatability to the diagnostic of type 2 diabetes in humans: baseline fasting glucose and insulin, glucose tolerance test, insulin sensitivity index, and body type composition. Improvements on these clinical values are essential for the progression of a novel potential therapeutic molecule through a preclinical and clinical pipeline.
Three-dimensional simulation of a rock slide impact into water

The steep-sided fjords of western Norway have experienced numerous rock slide events that sometimes produced devastating tsunamis. The 1934 slide in the Tafjord region, when some 3 million cubic meters of rock plunged into the water, resulted in waves tens of meters high that destroyed two villages and killed about 40 people. A similarly dangerous situation exists now in Sunnylvsfjord, where a major expanding crack in the fjord wall at Aknes threatens to release from 5 to 40 million cubic meters of rock into the water. Such an event would devastate a large region, including the Geiranger Fjord, a UN World Heritage Site that is extremely popular with tourists. The Norwegian Government's Aknes-Tafjord project is responsible for studying and monitoring the potential slide area and for providing adequate warning to protect lives and property. In order to better understand tsunami generation from such events, we have performed 3-dimensional fully compressible hydrodynamical simulations of the impact of a large number of boulders from a steep slope into a deep body of water. We use the Los Alamos/SAIC adaptive-mesh-refined SAGE code, previously used to model tsunamis from underwater explosions, asteroid impacts, and both subaqueous and subaerial landslide sources. We find the interaction of boulders and water to be extremely turbulent and dissipative. It differs markedly from simulations of large-block impacts in similar geometry. No more than about 15% of the potential energy of the boulders ends up in the water wave. The rest of the energy goes into heating the boulders (and presumably fragmenting them, though that physics is not included) into generating winds, heating air and water, and generating turbulence. In the near field, the waves produced by the impact can be quite high -- tens of meters -- and have the potential to devastate coastlines at substantial distances from the site along a narrow fjord system.

The intraoperative progression of a simple or occult pneumothorax into a tension pneumothorax can be a devastating clinical scenario. Routine use of prophylactic thoracostomy prior to anesthesia and initiation of controlled ventilation in patients with simple or occult pneumothorax remains controversial. We report the case of a 75-year-old trauma patient with an insignificant pneumothorax on the right who developed an intraoperative tension pneumothorax on the left side while undergoing thoracic spine stabilization surgery in the prone position. Management of an intraoperative tension pneumothorax requires prompt recognition and treatment; however, the prone position presents an additional challenge of readily accessing the standard anatomic sites for pleural puncture and air drainage.

Lymphatic filariasis is a parasitic infection that causes a devastating public health and socioeconomic burden with an estimated infection of over 120 million individuals worldwide. The infection is caused by three closely related nematode parasites, namely, Wuchereria bancrofti, Brugia malayi, and B. timori, which are transmitted to human through mosquitoes of Anopheles, Culex, and Aedes genera. The species have many ecological variants and are diversified in terms of their genetic fingerprint. The rapid spread of the disease and the genetic diversification cause the lymphatic filarial parasites to respond differently to diagnostic and therapeutic interventions. This in turn prompts the current challenge encountered in its management. Furthermore, most of the chemical medications used are characterized by adverse side effects. These complications urgently warrant intense prospecting on bio-chemicals that have potent efficacy against either the filarial worms or thier vector. In lieu of this, we presented a review on recent literature that reported the efficacy of filaricidal biochemicals and those employed as vector control agents. In addition, methods used for biochemical extraction, screening procedures, and structure of the bioactive compounds were also presented. PMID:24298292
Potential therapeutic applications of plant toxin-ricin in cancer: challenges and advances.

Cancer is one of the most common devastating disease affecting millions of people per year worldwide. To fight against cancer, a number of natural plant compounds have been exploited by researchers to discover novel anti-cancer therapeutics with minimum or no side effects and plants have proved their usefulness in anti-cancer therapy in past few years. Ricin, a cytotoxic plant protein isolated from castor bean seeds, is a ribosome-inactivating protein which destroys the cells by inhibiting proteins synthesis. Ricin presents great potential as anti-cancer agent and exerts its anti-cancer activity by inducing apoptosis in cancer cells. In this review, we summarize the current information on anti-cancer properties of plant toxin ricin, its potential applications in cancer therapy, challenges associated with its use as therapeutic agent and the recent advances made to overcome these challenges. Nanotechnology could open the doors for quick development of ricin-based anti-cancer therapeutics. Conceivably, ricin may serve as a chemotherapeutic agent against cancer by utilizing nanocarriers for its targeted delivery to cancer cells.
The concept of skin bleaching in Africa and its devastating health implications.

Africa is considered a continent of mystery and intrigue with absurd concepts and beliefs. Cosmetic dermatology is no less intriguing than other issues. While quick judgement may be passed condemning attitudes and misconceptions in this field, we need to analyze factors that contribute to such ideas. Acquiring a lighter skin forms the basis of Skin Care and Cosmetology in dark skinned people. This regrettably has far reaching devastating effects on health and individual finances. This in return has enriched unscrupulous stake holders. Help from the international medical fraternity and the pharmaceutical/cosmetology industry is required to end this evil.

Our previous work has shown that ocean impacts of asteroids below 500 m in diameter do not produce devastating long-distance tsunamis. Nevertheless, a significant portion of the ocean lies close enough to land that near-field effects may prove to be the greatest danger from asteroid impacts in the ocean. Crown splashes and central jets that rise up many kilometres into the atmosphere can produce, upon their collapse, highly non-linear breaking waves that could devastate shorelines within a hundred kilometres of the impact site. We present illustrative calculations, in two and three dimensions, of such impacts for a range of asteroidmore » sizes and impact angles. We find that, as for land impacts, the greatest dangers from oceanic impacts are the short-term near-field, and long-term atmospheric effects.« less

Political Repression Against Soviet Astronomers in the 1930s
NASA Astrophysics Data System (ADS)
Eremmeva, A. I.
1993-12-01
The Soviet government's repression of the Russian intelligentsia in the late 1930s had a devastating effect on astronomy. This period was marked by the strengthening of a rigid ideology in society and a growing atmosphere of suspicion, fear, and spy mania. Under these conditions the international nature of astronomy--in particular the need for foreign contacts--became the excuse for accusations of "wrecking" against astronomers. The fate of individual astronomers and institutions depended greatly, however, on local circumstances. For example, the general political repression of the 1930s began in Leningrad at a time when Pulkovo Observatory director B. P. Gerasimovich was engaged in a sharp conflict with a small group of junior staff led by V. A. Ambartsumian. In addition, the very first arrest of a Leningrad astronomer--namely the arrest of B. V. Numerov--appears to have initiated a cascading series of arrests that spread like an avalanche through the close-knit com- munity of Leningrad astronomers. These two factors led to the devastating ruin of Pulkovo. Completely different circumstances saved GAISh. This was a com- paratively young institute whose junior staff had spent its formative years at GAISh rather than joining the staff from out- side (as had been the case at Pulkovo). Thus the GAISh staff had a greater degree of homogeneity and solidarity, and this, in turn, may explain why the ideological department at GAISh (the "partburo") conducted itself in a manner that differed sharply from that of the "partburo" at Pulkovo. Thanks to these circum- stances not even one arrest occurred at GAISh. The directors of Pulkovo and GAISh came from very similar back- grounds, but the different conditions at Pulkovo and GAISh led to dramatic differences in their fates: execution for B. P. Gerasimovich in 1937 and "only" the persecution of GAISh director V. G. Fesenkov. The persecution of V. G. Fesenkov included his dismissal from the post of chairman of the Astronomical Council in 1937 and his removal as director of GAISh in 1939.

The emergence of drug resistance has devastating economic and social consequences, a testimonial of which is the rise and fall of inhibitors against the respiratory component cytochrome bc1 complex, a time tested and highly effective target for disease control. Unfortunately, the mechanism of resistance is a multivariate problem, including primarily mutations in the gene of the cytochrome b subunit but also activation of alternative pathways of ubiquinol oxidation and pharmacokinetic effects. There is a considerable interest in designing new bc1 inhibitors with novel modes of binding and lower propensity to induce the development of resistance. The accumulation of crystallographic data of bc1 complexes with and without inhibitors bound provides the structural basis for rational drug design. In particular, the cytochrome b subunit offers two distinct active sites that can be targeted for inhibition - the quinol oxidation site and the quinone reduction site. This review brings together available structural information of inhibited bc1 by various quinol oxidation- and reduction-site inhibitors, the inhibitor binding modes, conformational changes upon inhibitor binding of side chains in the active site and large scale domain movements of the iron-sulfur protein subunit. Structural data analysis provides a clear understanding of where and why existing inhibitors fail and points towards promising alternatives. PMID:23688079

Environmental public health disasters involving hazardous contaminants may have devastating effects. While much is known about their immediate devastation, far less is known about long-term impacts of these disasters. Extensive latent and chronic long-term public health effects may occur. Careful evaluation of contaminant exposures and long-term health outcomes within the constraints imposed by limited financial resources is essential. Here, we review epidemiologic methods lessons learned from conducting long-term evaluations of four environmental public health disasters involving hazardous contaminants at Chernobyl, the World Trade Center, Bhopal, and Graniteville (South Carolina, USA). We found several lessons learned which have direct implications for the on-going disaster recovery work following the Fukushima radiation disaster or for future disasters. These lessons should prove useful in understanding and mitigating latent health effects that may result from the nuclear reactor accident in Japan or future environmental public health disasters.

Lead toxicity is an important environmental disease and its effects on the human body can be devastating. Unique exposures to Special Operations Forces personnel may include use of firing ranges, use of automotive fuels, production of ammunition, and bodily retention of bullets. Toxicity may degrade physical and psychological fitness, and cause long-term negative health outcomes. Specific effects on fine motor movements, reaction times, and global function could negatively affect shooting skills and decision-making. Biologic monitoring and chelation treatment are poor solutions for protecting this population. Through primary prevention, Special Operations Forces personnel can be protected, in any environment, from the devastating effects of lead exposure. This article offers tools to physicians, environmental service officers, and Special Operations Medics for primary prevention of lead poisoning in the conventional and the austere or forward deployed environments. 2018.

Craniotomies involving the midline are regular practice in neurosurgery, during which injury to the superior sagittal sinus (SSS), an uncommon yet devastating event, may occur. The midline tends to be the most common landmark used to identify the position of the SSS. In this study we examined the reliability of the midline as a landmark for the SSS. We performed bilateral craniectomies on eight cadaveric heads, preserving the coronal, sagittal, and lambdoid sutures. The width of the SSS and its displacement from midline were measured on the cadaveric specimens and on 105 normal magnetic resonance images (MRIs) of the head at the following locations: halfway between nasion and bregma (NB), bregma (B), halfway between bregma and lambda (BL), lambda (L), and inion (I). In all cadaveric specimens, the SSS was partially or totally displaced toward one side of midline, usually to the right. It tended to be closer to midline in the frontal region and more displaced posteriorly. The SSS usually drained into the right-side transverse sinus. The mean width of the SSS was 4.3, 5.9, 6.9, 7.9, and 7.8 mm, and the average displacement from midline was 4.3, 6.3, 5.5, 6.9, and 6.0 mm for NB, B, BL, L, and I, respectively. These measurements were then compared with those obtained from the MRIs. The SSS was consistently displaced on either side of midline. Thus, the midline is not reliable for identifying the SSS, and caution should be used within 6-10 mm on either side of midline.
Can brain impermeable BACE1 inhibitors serve as anti-CAA medicine?
Li, Jian-Ming; Huang, Li-Ling; Liu, Fei; Tang, Bei-Sha; Yan, Xiao-Xin

Cerebral amyloid angiopathy (CAA) is characterized by the deposition of ß-amyloid peptides (Aß) in and surrounding the wall of microvasculature in the central nervous system, together with parenchymal amyloid plaques collectively referred to as cerebral amyloidosis, which occurs in the brain commonly among the elderly and more frequently in patients with Alzheimer's disease (AD). CAA is associated with vascular injury and may cause devastating neurological outcomes. No therapeutic approach is available for this lesion to date. ß-Secretase 1 (BACE1) is the enzyme initiating Aß production. Brain permeable BACE1 inhibitors targeting primarily at the parenchymal plaque pathology are currently evaluated in clinical trials. This article presents findings in support of a role of BACE1 elevation in the development of CAA, in addition to plaque pathogenesis. The rationale, feasibility, benefit and strategic issues for developing BACE1 inhibitors against CAA are discussed. Brain impermeable compounds are considered preferable as they might exhibit sufficient anti-CAA efficacy without causing significant neuronal/synaptic side effects. Early pharmacological intervention to the pathogenesis of CAA is expected to provide significant protection for cerebral vascular health and hence brain health. Brain impermeable BACE1 inhibitors should be optimized and tested as potential anti-CAA therapeutics.

Background: Environmental public health disasters involving hazardous contaminants may have devastating effects. While much is known about their immediate devastation, far less is known about long-term impacts of these disasters. Extensive latent and chronic long-term public health effects may occur. Careful evaluation of contaminant exposures and long-term health outcomes within the constraints imposed by limited financial resources is essential. Methods: Here, we review epidemiologic methods lessons learned from conducting long-term evaluations of four environmental public health disasters involving hazardous contaminants at Chernobyl, the World Trade Center, Bhopal, and Graniteville (South Carolina, USA). Findings: We found several lessons learned which have direct implications for the on-going disaster recovery work following the Fukushima radiation disaster or for future disasters. Interpretation: These lessons should prove useful in understanding and mitigating latent health effects that may result from the nuclear reactor accident in Japan or future environmental public health disasters.

Parkinson's disease (PD) is a devastating neurodegenerative disorder characterized by degeneration of the nigrostriatal dopaminergic pathway. Because the current therapies only lead to temporary, limited improvement and have severe side effects, new approaches to treat PD need to be developed. To discover new targets for potential therapeutic intervention, a chemical genetic approach involving the use of small molecules as pharmacological tools has been implemented. First, a screening of an in-house chemical library on a well-established cellular model of PD was done followed by a detailed pharmacological analysis of the hits. Here, we report the results found for the small heterocyclic derivative called SC001, which after different enzymatic assays was revealed to be a new glycogen synthase kinase-3 (GSK-3) inhibitor with IC50 = 3.38 ± 0.08 μM. To confirm that GSK-3 could be a good target for PD, the evaluation of a set of structurally diverse GSK-3 inhibitors as neuroprotective agents for PD was performed. Results show that inhibitors of GSK-3 have neuroprotective effects in vitro representing a new pharmacological option for the disease-modifying treatment of PD. Furthermore, we show that SC001 is able to cross the blood–brain barrier, protects dopaminergic neurons, and reduces microglia activation in in vivo models of Parkinson disease, being a good candidate for further drug development.

Enzalutamide is a second-generation androgen receptor (AR) antagonist for the treatment of metastatic castration-resistant prostate cancer (mCRPC). Unfortunately, AR dysfunction means that resistance to enzalutamide will eventually develop. Thus, novel agents are urgently needed to treat this devastating disease. Triptolide (TPL), a key active compound extracted from the Chinese herb Thunder God Vine ( Tripterygium wilfordii Hook F.), possesses anti-cancer activity in human prostate cancer cells. However, the effects of TPL against CRPC cells and the underlying mechanism of any such effect are unknown. In this study, we found that TPL at low dose inhibits the transactivation activity of both full-length and truncated AR without changing their protein levels. Interestingly, TPL inhibits phosphorylation of AR and its CRPC-associated variant AR-V7 at Ser515 through XPB/CDK7. As a result, TPL suppresses the binding of AR to promoter regions in AR target genes along with reduced TFIIH and RNA Pol II recruitment. Moreover, TPL at low dose reduces the viability of prostate cancer cells expressing AR or AR-Vs. Low-dose TPL also shows a synergistic effect with enzalutamide to inhibit CRPC cell survival in vitro , and enhances the anti-cancer effect of enzalutamide on CRPC xenografts with minimal side effects. Taken together, our data demonstrate that TPL targets the transactivation activity of both full-length and truncated ARs. Our results also suggest that TPL is a potential drug for CRPC, and can be used in combination with enzalutamide to treat CRPC.

Penile fracture following husband abuse: a case report.
Dienye, Paul O; Jebbin, Nze J; Gbeneol, Precious K
2009-12-01
The case of a 35-year-old fisherman who presented in a rural clinic with a sudden onset of painful penile swelling affecting the left lateral side with associated rapid detumescence is reported. He had tried to coerce his wife to a sexual intercourse when she forcefully bent his penis. He was initially managed with cold applications, oral diclofenac potassium, chymoral, and splinting of the penis and then referred to the urological services of a teaching hospital. He defaulted only to re-present about 2 weeks later with some improvement in his symptoms. Further advice to see the urologist was also rebuffed on financial grounds. When he reported about 1 month later, he was assessed to have grade 3 erectile dysfunction. In conclusion, penile fracture is a rare condition which follows unphysiological bending of the tumescent penis during sexual intercourse or masturbation. That following husband abuse is rarer. The sequelae can be devastating.
Warfare, genocide, and ethnic conflict: a Darwinian approach
2010-01-01
As the 21st century dawns, I reflect on the history of humankind with growing concern about the need to understand the underlying biological and cultural roots of ethnic conflict and warfare. In the many studies of human conflict, innate biological predispositions have been neglected. This article is the third part of a series of seminars for medical residents at the University of Texas Southwestern Medical School at Dallas (see http://adarwinstudygroup.org/). The series starts with in-depth coverage of Darwinian natural and sexual selection, with examples from the domestication of animals and plants and the crisis of antibiotic resistance. The series strives to show how biology has been neglected in the study of the we-they orientation of human behavior, with its devastating consequences. The subject material is profoundly disturbing, as it looks at “human nature” and contrasts the “dark side” of human behavior with the opposite, profoundly caring and loving side. PMID:21240320
Between East and West: polio vaccination across the Iron Curtain in Cold War Hungary.
Vargha, Dora
2014-01-01
In 1950s Hungary, with an economy and infrastructure still devastated from World War II and facing further hardships, thousands of children became permanently disabled and many died in the severe polio epidemic that shook the globe. The relatively new communist regime invested significantly in solving the public health crisis, initially importing a vaccine from the West and later turning to the East for a new solution. Through the history of polio vaccination in Hungary, this article shows how Cold War politics shaped vaccine evaluation and implementation in the 1950s. On the one hand, the threat of polio created a safe place for hitherto unprecedented, open cooperation among governments and scientific communities on the two sides of the Iron Curtain. On the other hand, Cold War rhetoric influenced scientific evaluation of vaccines, choices of disease prevention, and ultimately the eradication of polio.
Protein kinase A and fungal virulence: a sinister side to a conserved nutrient sensing pathway.
Fuller, Kevin K; Rhodes, Judith C
2012-01-01
Diverse fungal species are the cause of devastating agricultural and human diseases. As successful pathogenesis is dependent upon the ability of the fungus to adapt to the nutritional and chemical environment of the host, the understanding of signaling pathways required for such adaptation will provide insights into the virulence of these pathogens and the potential identification of novel targets for antifungal intervention. The cAMP-PKA signaling pathway is well conserved across eukaryotes. In the nonpathogenic yeast, S. cerevisiae, PKA is activated in response to extracellular nutrients and subsequently regulates metabolism and growth. Importantly, this pathway is also a regulator of pathogenesis, as defects in PKA signaling lead to an attenuation of virulence in diverse plant and human pathogenic fungi. This review will compare and contrast PKA signaling in S. cerevisiae vs. various pathogenic species and provide a framework for the role of this pathway in regulating fungal virulence.

Purpose: Although ionizing radiation is critical in treating cancer, radiation-induced fibrosis (RIF) can have a devastating impact on patients' quality of life. The molecular changes leading to radiation-induced fibrosis must be elucidated so that novel treatments can be designed. Methods and Materials: To determine whether microRNAs (miRs) could be responsible for RIF, the fibrotic process was induced in the right hind legs of 9-week old CH3 mice by a single-fraction dose of irradiation to 35 Gy, and the left leg served as an unirradiated control. Fibrosis was quantified by measurements of leg length compared with control leg length. By 120 days aftermore » irradiation, the irradiated legs were 20% (P=.013) shorter on average than were the control legs. Results: Tissue analysis was done on muscle, skin, and subcutaneous tissue from irradiated and control legs. Fibrosis was noted on both gross and histologic examination by use of a pentachrome stain. Microarrays were performed at various times after irradiation, including 7 days, 14 days, 50 days, 90 days, and 120 days after irradiation. miR-15a, miR-21, miR-30a, and miR-34a were the miRs with the most significant alteration by array with miR-34a, proving most significant on confirmation by reverse transcriptase polymerase chain reaction, c-Met, a known effector of fibrosis and downstream molecule of miR-34a, was evaluated by use of 2 cell lines: HCT116 and 1522. The cell lines were exposed to various stressors to induce miR changes, specifically ionizing radiation. Additionally, in vitro transfections with pre-miRs and anti-miRs confirmed the relationship of miR-34a and c-Met. Conclusions: Our data demonstrate an inverse relationship with miR-34a and c-Met; the upregulation of miR-34a in RIF causes inhibition of c-Met production. miRs may play a role in RIF; in particular, miR-34a should be investigated as a potential target to prevent or treat this devastating side effect of irradiation.« less

Cholangiocarcinoma (CCA) is a devastating disease due to no effective treatments available. Since the non-mineral functions of vitamin D emerges, 1α,25(OH)2D3, the active form of vitamin D, has been applied in anti-cancer researches. In this study, we demonstrated that both the 1α,25(OH)2D3 analog, MART-10, and 1α,25(OH)2D3 possessed anti-growth effect on human CCA cells with MART-10 much more potent than 1α,25(OH)2D3. The growth inhibition of both drugs were mediated by induction of G0/G1 cell cycle arrest through upregulation of p27 and downregulation of CDK4, CDK6, and cyclin D3. Human neutrophil gelatinase associated lipocalin (NGAL) was found to be involved in 1α,25(OH)2D3 and MART-10 meditated growth inhibition for CCA as knockdown of NGAL decreased Ki-67 expression in SNU308 cells and rendered SNU308 cells less responsive to 1α,25(OH)2D3 and MART-10 treatment. Vitamin D receptor (VDR) knockdown partly abolished MART-10-induced inhibition of NGAL and cell growth in SNU308 cells. The xenograft animal study demonstrated MART-10 could effectively repressed CCA growth in vivo without inducing obvious side effects. The IHC examination of human CCA specimen for VDR revealed that higher VDR expression was linked with better prognosis. Collectively, our results suggest that MART-10 could be a promising regimen for CCA treatment. PMID:28256614

Trypanosoma brucei parasites are kinetoplastid protozoa that devastate the health and economic well-being of millions of people in Africa through the disease human African trypanosomiasis (HAT). New chemotherapy has been eagerly awaited due to severe side effects and the drug resistance issues plaguing current drugs. Recently, there has been an emphasis on the use of medicinal plants worldwide. Morinda lucida Benth. is a popular medicinal plant widely distributed in Africa, and several research groups have reported on the antiprotozoal activities of this plant. In this study, we identified three novel tetracyclic iridoids, molucidin, ML-2-3, and ML-F52, from the CHCl3 fraction of M. lucida leaves, which possess activity against the GUTat 3.1 strain of T. brucei brucei. The 50% inhibitory concentrations (IC50) of molucidin, ML-2-3, and ML-F52 were 1.27 μM, 3.75 μM, and 0.43 μM, respectively. ML-2-3 and ML-F52 suppressed the expression of paraflagellum rod protein subunit 2, PFR-2, and caused cell cycle alteration, which preceded apoptosis induction in the bloodstream form of Trypanosoma parasites. Novel tetracyclic iridoids may be promising lead compounds for the development of new chemotherapies for African trypanosomal infections in humans and animals. PMID:26953191

Integrated mangrove-shrimp cultivation: Potential for blue carbon sequestration.
Ahmed, Nesar; Thompson, Shirley; Glaser, Marion
2018-05-01
Globally, shrimp farming has had devastating effects on mangrove forests. However, mangroves are the most carbon-rich forests, with blue carbon (i.e., carbon in coastal and marine ecosystems) emissions seriously augmented due to devastating effects on mangrove forests. Nevertheless, integrated mangrove-shrimp cultivation has emerged as a part of the potential solution to blue carbon emissions. Integrated mangrove-shrimp farming is also known as organic aquaculture if deforested mangrove area does not exceed 50% of the total farm area. Mangrove destruction is not permitted in organic aquaculture and the former mangrove area in parts of the shrimp farm shall be reforested to at least 50% during a period of maximum 5 years according to Naturland organic aquaculture standards. This article reviews integrated mangrove-shrimp cultivation that can help to sequester blue carbon through mangrove restoration, which can be an option for climate change mitigation. However, the adoption of integrated mangrove-shrimp cultivation could face several challenges that need to be addressed in order to realize substantial benefits from blue carbon sequestration.

Chemotherapy-induced peripheral neuropathy (CIPN) is a serious adverse side effect of many chemotherapeutic agents, affecting >60% of patients with cancer. Moreover, CIPN persists long into survivorship in approximately 20% to 30% of these patients. To the authors' knowledge, no drugs have been approved to date by the US Food and Drug Administration to effectively manage chemotherapy-induced neuropathic pain. The majority of the drugs tested for the management of CIPN aim at symptom relief, including pain and paresthesia, yet are not very efficacious. The authors propose that there is a need to acquire a more thorough understanding of the etiology of CIPN so that effective, mechanism-based, disease-modifying interventions can be developed. It is important to note that such interventions should not interfere with the antitumor effects of chemotherapy. Mitochondria are rod-shaped cellular organelles that represent the powerhouses of the cell, in that they convert oxygen and nutrients into the cellular energy "currency" adenosine triphosphate. In addition, mitochondria regulate cell death. Neuronal mitochondrial dysfunction and the associated nitro-oxidative stress represent crucial final common pathways of CIPN. Herein, the authors discuss the potential to prevent or reverse CIPN by protecting mitochondria and/or inhibiting nitro-oxidative stress with novel potential drugs, including the mitochondrial protectant pifithrin-μ, histone deacetylase 6 inhibitors, metformin, antioxidants, peroxynitrite decomposition catalysts, and anti-inflammatory mediators including interleukin 10. This review hopefully will contribute toward bridging the gap between preclinical research and the development of realistic novel therapeutic strategies to prevent or reverse the devastating neurotoxic effects of chemotherapy on the (peripheral) nervous system.

Corporate redemption and the seven deadly sins.
Pearson, A E
1992-01-01
Competitive purgatory is the sorry state of too many formerly proud U.S. corporations. They are languishing from the devastating effects of seven familiar sins: inconsistent product quality; slow response to the marketplace; lack of innovative, competitive products; uncompetitive cost structure; inadequate employee involvement; unresponsive customer service; and inefficient resource allocation. To make matters worse, the maladies are mostly management-induced, and the remedies most managers are employing-shifting strategy, reallocating resources, focusing on operations--are proving ineffective. The cures don't address the cause of the disease: negative, risk-averse, bureaucratic work environments that flourished in decades of easy growth but today are undermining competitive performance. What's needed is a total reinvention of the soft side of the organization to produce a work environment that stresses speed, Spartanism, innovation, and marketplace focus. First, top managers must decide what their company stands for and convince their employees of this uniqueness. Second, they must set standards that drive their business to worldclass levels and be tough about enforcing and raising them. Third, they must push constantly to ensure that enough innovations take place to change the company's future significantly. Three other factors are crucial: the right talent, an effective reward system, and CEOs who can drive the desired changes personally. Creating a dynamic work environment is not easy: it takes perseverance, flexibility, and commitment. But these efforts will pay off: how people tackle problems, work together, and think about their jobs are the activities that make a company great.
Drug development against sleeping sickness: old wine in new bottles?
Stein, J; Mogk, S; Mudogo, C N; Sommer, B P; Scholze, M; Meiwes, A; Huber, M; Gray, A; Duszenko, M
2014-01-01
Atoxyl, the first medicinal drug against human African trypanosomiasis (HAT), also known as sleeping sickness, was applied more than 100 years ago. Ever since, the search for more effective, more specific and less toxic drugs continued, leading to a set of compounds currently in use against this devastating disease. Unfortunately, none of these medicines fulfill modern pharmaceutical requirements and may be considered as therapeutic ultima ratio due to the many, often severe side effects. Starting with a historic overview on drug development against HAT, we present a selection of trypanosome specific pathways and enzymes considered as highly potent druggable targets. In addition, we describe cellular mechanisms the parasite uses for differentiation and cell density regulation and present our considerations how interference with these steps, elementary for life cycle progression and infection, may lead to new aspects of drug development. Finally we refer to our recent work about CNS infection that offers novel insights in how trypanosomes hide in an immune privileged area to establish a chronic state of the disease, thereby considering new ways for drug application. Depressingly, HAT specific drug development has failed over the last 30 years to produce better suited medicine. However, unraveling of parasite-specific pathways and cellular behavior together with the ability to produce high resolution structures of essential parasite proteins by X-ray crystallography, leads us to the optimistic view that development of an ultimate drug to eradicate sleeping sickness from the globe might just be around the corner.
Prophylactic antibiotics for percutaneous endovascular procedures.
Greaves, N S; Katsogridakis, E; Faris, B; Murray, D
2017-04-01
Percutaneous endovascular techniques are used increasingly in the vascular armamentarium. Commonly performed as day case procedures under local anaesthetic, they are suited to the highly co-morbid vascular patient population. Furthermore, technological advances have resulted in ever improving outcomes for aneurysmal and occlusive disease. Endovascular procedures such as endovascular aneurysm repair or iliac artery stenting are traditionally associated with reduced infectious complications compared to equivalent open techniques. However, when they do occur, they are equally devastating and often associated with limb loss or death since the only effective treatment is removal of all infected material. The use of prophylactic antibiotics to reduce infectious complications in open surgery has a strong evidence base, but there is no equivalent data for percutaneous endovascular procedures. The Society of Interventional Radiology published formal guidelines for adult antibiotic prophylaxis in 2010. Based on relatively poor quality studies, they nevertheless represent the first official guidance in the field and stress the need for large randomised controlled trials to further guide the debate. Broadly, the benefits of reduced infectious complications must be balanced against the fiscal cost of increased antimicrobial usage, promotion of multi-drug resistant organisms and patient side-effect profiles. The number needed to treat to prevent one infection is high yet without it a small but significant number of patients will suffer serious adverse outcomes secondary to infection of endovascular prostheses. This review article aims to summarise the evidence around the use of prophylactic antibiotics in percutaneous endovascular procedures.
Oxygen--a limiting factor for brain recovery.
Hadanny, Amir; Efrati, Shai
2015-09-01
Effective brain metabolism is highly dependent on a narrow therapeutic window of oxygen. In major insults to the brain (e.g., intracerebral hemorrhage), a slight decrease in oxygen supply, as occurs in a hypobaric environment at high altitude, has devastating effects on the injured brain tissue. Conversely, increasing brain oxygenation, by the use of hyperbaric oxygen therapy, can improve brain metabolism and its dependent regenerative processes.

Devastating brain injuries (DBIs) profoundly damage cerebral function and frequently cause death. DBI survivors admitted to critical care will suffer both intracranial and extracranial effects from their brain injury. The indicators of quality care in DBI are not completely defined, and despite best efforts many patients will not survive, although others may have better outcomes than originally anticipated. Inaccuracies in prognostication can result in premature termination of life support, thereby biasing outcomes research and creating a self-fulfilling cycle where the predicted course is almost invariably dismal. Because of the potential complexities and controversies involved in the management of devastating brain injury, the Neurocritical Care Society organized a panel of expert clinicians from neurocritical care, neuroanesthesia, neurology, neurosurgery, emergency medicine, nursing, and pharmacy to develop an evidence-based guideline with practice recommendations. The panel intends for this guideline to be used by critical care physicians, neurologists, emergency physicians, and other health professionals, with specific emphasis on management during the first 72-h post-injury. Following an extensive literature review, the panel used the GRADE methodology to evaluate the robustness of the data. They made actionable recommendations based on the quality of evidence, as well as on considerations of risk: benefit ratios, cost, and user preference. The panel generated recommendations regarding prognostication, psychosocial issues, and ethical considerations.

The Kashmir earthquake also known as South Asia earthquake, hit both sides of Jammu & Kashmir on October 8th 2005 and was quite devastating with official toll of deaths being 73,276 in Pakistan Administered Kashmir (POK) and 1,360 deaths in the Indian administered Kashmir. The injured registering on the two sides were around 100,000 and 6,300 respectively. This was followed by a series of aftershocks on both sides for another 3 weeks A follow up (retrospective) survey was conducted by the Department of Community Medicine SKIMS, Srinagar in collaboration with National Institute of Orthopedically Handicapped (NIOH), Kolkata, immediately after the devastating earthquake of October 2008 that hit Kashmir (Jammu & Kashmir- India) and northern parts of India with the objectives to know the nature of the injuries, magnitude of disabilities, rehabilitative services provided, and service satisfaction. Addresses of earthquake victims registered with various health institutions, Tertiary Care Centre, orthopaedic hospital, district hospital and Composite Regional Centre (CRC)(through which rehabilitative services were provided initially) were collected and referral details, if any, to various health institutions. They were visited at their residence and interviewed for the desired information as per proforma by a team comprising of a doctor, physiotherapist, prosthetist and orthotist by making house to house survey in the earthquake areas. An effort for non registered injured victims, if any in the locality, was also made with health or district authorities to trace non registered injured persons The study shows that majority of injured were young adults and adolescent females, and primarily upper extremities, cervical spine and head were injured. The severely injured were shifted within 12-24 hrs to referral hospitals. In 2/3rd of affected families, single member was injured, whereas in 1/3rd at least two were injured. The case fatality rate was <1% because of low prevalence of crush injuries, and quick medical relief/management of the injured. A significant number of seriously injured victims (40%) required rehabilitative services and assistive devices. Probably a quick intervention by medical rehabilitative services, including facility of assistive aids and necessary customised prosthetics and orthotics first time in such disaster, has resulted in high client satisfaction, early restoration of functional and psychological status of the injured victims. A collective effort by various public and private agencies with timely response at referral hospitals to various injuries reduced the frequency and chances of major disabling conditions. Intervention by CRC for providing assistive devices has also significantly helped in bringing back the functional and psychological status of the injured victims. Proper inter-sectorial coordination, better managerial skills, training of community volunteers (NGOs), and professionals on disaster management may further reduce the injury related disability and its impact. There is need of updating medico-surgical disaster management training for health care workers on continuous basis at various levels.

Making decisions for a patient affected by sudden devastating illness or injury traumatizes a patient's family and loved ones. Even in the absence of an emergency, surrogates making end-of-life treatment decisions may experience negative emotional effects. Helping surrogates with these end-of-life decisions under emergent conditions requires the emergency physician (EP) to be clear, making medical recommendations with sensitivity. This model for emergency department (ED) end-of-life communications after acute devastating events comprises the following steps: 1) determine the patient's decision-making capacity; 2) identify the legal surrogate; 3) elicit patient values as expressed in completed advance directives; 4) determine patient/surrogate understanding of the life-limiting event and expectant treatment goals; 5) convey physician understanding of the event, including prognosis, treatment options, and recommendation; 6) share decisions regarding withdrawing or withholding of resuscitative efforts, using available resources and considering options for organ donation; and 7) revise treatment goals as needed. Emergency physicians should break bad news compassionately, yet sufficiently, so that surrogate and family understand both the gravity of the situation and the lack of long-term benefit of continued life-sustaining interventions. EPs should also help the surrogate and family understand that palliative care addresses comfort needs of the patient including adequate treatment for pain, dyspnea, or anxiety. Part I of this communications model reviews determination of decision-making capacity, surrogacy laws, and advance directives, including legal definitions and application of these steps; Part II (which will appear in a future issue of AEM) covers communication moving from resuscitative to end-of-life and palliative treatment. EPs should recognize acute devastating illness or injuries, when appropriate, as opportunities to initiate end-of-life discussions and to implement shared decisions. © 2012 by the Society for Academic Emergency Medicine.

Epilepsy--the propensity toward recurrent, unprovoked seizures--is a devastating disease affecting 65 million people worldwide. Understanding and treating this disease remains a challenge, as seizures manifest through mechanisms and features that span spatial and temporal scales. Here we address this challenge through the analysis and modelling of human brain voltage activity recorded simultaneously across microscopic and macroscopic spatial scales. We show that during seizure large-scale neural populations spanning centimetres of cortex coordinate with small neural groups spanning cortical columns, and provide evidence that rapidly propagating waves of activity underlie this increased inter-scale coupling. We develop a corresponding computational model to propose specific mechanisms--namely, the effects of an increased extracellular potassium concentration diffusing in space--that support the observed spatiotemporal dynamics. Understanding the multi-scale, spatiotemporal dynamics of human seizures--and connecting these dynamics to specific biological mechanisms--promises new insights to treat this devastating disease.
RhoA/Rho-kinase signaling: a therapeutic target in pulmonary hypertension.
Barman, Scott A; Zhu, Shu; White, Richard E
2009-01-01
Pulmonary arterial hypertension (PAH) is a devastating disease characterized by progressive elevation of pulmonary arterial pressure and vascular resistance due to pulmonary vasoconstriction and vessel remodeling as well as inflammation. Rho-kinases (ROCKs) are one of the best-described effectors of the small G-protein RhoA, and ROCKs are involved in a variety of cellular functions including muscle cell contraction, proliferation and vascular inflammation through inhibition of myosin light chain phosphatase and activation of downstream mediators. A plethora of evidence in animal models suggests that heightened RhoA/ROCK signaling is important in the pathogenesis of pulmonary hypertension by causing enhanced constriction and remodeling of the pulmonary vasculature. Both animal and clinical studies suggest that ROCK inhibitors are effective for treatment of severe PAH with minimal risk, which supports the premise that ROCKs are important therapeutic targets in pulmonary hypertension and that ROCK inhibitors are a promising new class of drugs for this devastating disease.
The malpractice crisis in obstetrics and gynecology: is there a solution?
Barber, H. R.
1991-01-01
The malpractice ripoff began when the no-fault automobile accident law was passed. Many lawyers were in a panic at this time and turned to medical malpractice litigation to make a living. It became the conduit to quick wealth. The patient was the loser, the lawyer the winner, and the physician often devastated by the patient's ingratitude. For a patient-plaintiff to maintain a successful lawsuit for medical negligence against a physician, four elements must be alleged and proved in a court of law: duty, breach of duty, causation, and damages. Each must be proved by a patient to prevail against a physician. Since this is very difficult to do, the lawyers have subtly brought in a new approach called maloccurrence. This is defined as a bad outcome unrelated to the quality of care provided. The lawyers need not prove the four elements to win a malpractice case; many are won on deceit and in violation of the law by introducing the concept of maloccurrence. Not only are tort reforms needed but out of court alternatives must be mandated by law or our health care delivery system will be destroyed. Government interference and the malpractice ripoff has had a devastating effect on the talent attracted to medical school, and the number of applicants is falling rapidly. The medical malpractice crisis could soon be translated into a health delivery service crisis. Concerned citizens must join together with the medical profession and leaders of the legal profession to halt this monstrous injustice. The litigation milieu has not only paralyzed the health care industry but it has had a devastating effect across the board on the way Americans live and do business. It must be solved now for justice delayed is justice denied. PMID:2049569

The world has recently witnessed several large scale natural disasters. These include the Asian tsunami which devastated many of the countries around the rim of the Indian Ocean in December 2004, extensive flooding in many parts of Europe in August 2005, hurricane katrina (September 2005), the outbreak of severe acute respiratory syndrome (SARS) in many regions of Asia and Canada in 2003 and the Pakistan earthquake (towards the end of 2005). Such emergency and disaster situations (E&DS) serve to underscore the utter chaos that ensues in the aftermath of such events, the many casualties and lives lost not to mention the devastation and destruction that is left behind. One recurring theme that is apparent in all these situations is that, irrespective of the warnings of imminent threats, countries have not been prepared and ready to exhibit effective and efficient crisis management. This paper examines the application of the tools, techniques and processes of the knowledge economy to develop a prescriptive model that will support superior decision making in E&DS, thereby enabling effective and efficient crisis management.

Self-cutting injuries have a low mortality rate, but this type of injuries has special clinical significance because they have the potential of leading to devastating disability and repeated suicide attempts. The purpose of this study is to analyze the nature and outcomes of wrist-cutting injuries. A retrospective study was designed in order to investigate 41 suicide attempts by wrist cutting attended to Uludag University Faculty of Medicine Emergency Department between June 2008 and December 2014. The patients were analyzed for age, gender, alcohol intake, psychological state, prior suicide attempts, and clinical features such as injury side, injury pattern, and used tool. It was seen that the severity of wrist-cutting injury variates between gender and age. Alcohol or drug consumption and having a diagnosed psychiatric disorder create a higher risk for extensive wrist lacerations. It was seen that skin only lacerations were most likely to repeat the act and therefore are most in need of psychiatric intervention. Level III, retrospective study.

Epilepsy is a devastating disorder that impacts on patients' quality of life, irrespective of use of anti epileptic drugs (AEDs). This study estimates the health-related quality of life (HRQOL) and its associated predictors among epilepsy patients receiving AEDs. A total of 175 epilepsy patients already receiving AED for at least 3 months were randomly selected and interviewed from mental clinics at Mulago and Butabika national referral hospitals in Uganda between May - July 2011. A HRQOL index, the primary outcome, was constructed using items from Quality Of Life in Epilepsy Inventory (QOLIE-31) and the Hospital Anxiety and Depression Scale (HADS) questionnaires. The internal consistency and adequacy of these items was also computed using Cronbach's alpha and Kaiser-Meyer-Olkin tests. Partial correlations were used to evaluate the contribution of the health dimensions (mental, psychological, social, physical functioning and emotional well being) and, multiple linear regressions to determine factors independently associated with HRQOL. Just about half of the respondents (54%) were males, and nearly two thirds (62%) had received AEDs for at least 12 months. The average age was 26.6 years (SD = 11.1). The overall HRQOL mean score was 58 (SD = 13) on a scale of 0-100. The average scores of different dimensions or subscales ranged from 41 (physical) to 65 (psychological). At least three quarters (75%) of all subscales had good internal consistency and adequacy. The largest variations in the overall HRQOL were explained by social and mental functioning; each accounting for about 30% of the difference in the HRQOL but seizure control features explained a little (6%) variation. Factors negatively associated with HRQOL were poly-therapy (-1.16, p = 0.01) and frequency of seizures (-2.29, p = 0.00). Other factors associated with overall HRQOL included drug side effects, sex, marital status and education. Duration on AEDs was not a significant predictor of HRQOL. The HRQOL for epilepsy patients on AEDs is very low. The predictors of low HRQOL were socio factors (marital status, education) and drug side effects, frequency of seizure, and type of therapy.
Pleiotropic effects of statins: new therapeutic targets in drug design.
Bedi, Onkar; Dhawan, Veena; Sharma, P L; Kumar, Puneet
2016-07-01
The HMG Co-enzyme inhibitors and new lipid-modifying agents expand their new therapeutic target options in the field of medical profession. Statins have been described as the most effective class of drugs to reduce serum cholesterol levels. Since the discovery of the first statin nearly 30 years ago, these drugs have become the main therapeutic approach to lower cholesterol levels. The present scientific research demonstrates numerous non-lipid modifiable effects of statins termed as pleiotropic effects of statins, which could be beneficial for the treatment of various devastating disorders. The most important positive effects of statins are anti-inflammatory, anti-proliferative, antioxidant, immunomodulatory, neuroprotective, anti-diabetes, and antithrombotic, improving endothelial dysfunction and attenuating vascular remodeling besides many others which are discussed under the scope of this review. In particular, inhibition of Rho and its downstream target, Rho-associated coiled-coil-containing protein kinase (ROCK), and their agonistic action on peroxisome proliferator-activated receptors (PPARs) can be viewed as the principle mechanisms underlying the pleiotropic effects of statins. With gradually increasing knowledge of new therapeutic targets of statins, their use has also been advocated in chronic inflammatory disorders for example rheumatoid arthritis (RA) and in systemic lupus erythematosus (SLE). In the scope of review, we highlight statins and their pleiotropic effects with reference to their harmful and beneficial effects as a novel approach for their use in the treatment of devastating disorders.

Evolutionary co-option of existing structures for new functions is a powerful yet understudied mechanism for generating novelty. Trap-jaw ants of the predatory genus Odontomachus are capable of some of the fastest self-propelled appendage movements ever recorded; their devastating strikes are not only used to disable and capture prey, but produce enough force to launch the ants into the air. We tested four Odontomachus species in a variety of behavioral contexts to examine if their mandibles have been co-opted for an escape mechanism through ballistic propulsion. We found that nest proximity makes no difference in interactions with prey, but that prey size has a strong influence on the suite of behaviors employed by the ants. In trials involving a potential threat (another trap-jaw ant species), vertical jumps were significantly more common in ants acting as intruders than in residents (i.e. a dangerous context), while horizontal jumps occurred at the same rate in both contexts. Additionally, horizontal jump trajectories were heavily influenced by the angle at which the substrate was struck and appear to be under little control by the ant. We conclude that while horizontal jumps may be accidental side-effects of strikes against hard surfaces, vertical escape jumps are likely intentional defensive behaviors that have been co-opted from the original prey-gathering and food-processing functions of Odontomachus jaws.
No blank slates: Pre-existing schemas about pharmaceuticals predict memory for side effects.
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.

[Cooperation and support activities of infection control after the Great East Japan Earthquake].
Hatta, Masumitsu; Kaku, Mitsuo

On 11 March 2011, an earthquake measuring 9.0 on the Richter scale occurred off the northeast coast of Honshu Island, Japan, produced a devastating tsunami that destroyed many towns and villages near the coast in Iwate, Miyagi, and Fukushima prefectures. Miyagi Prefecture was the area most severely devastated by the tsunami, with extensive loss of life and property; hundreds of thousands of people lost their houses and were forced to move to evacuation areas. In the days and weeks following devastating natural disasters, the threat of infectious disease outbreak is high. We initiated cooperation and support activities in terms of infection control at evacuation centers in the aftermath of the disaster. For example, we assessed sanitary and infectious risk factors in evacuation centers, in collaboration with Miyagi Prefectural Government and public health centers in the devastated area, to prevent the transmission of infectious diseases among evacuees. We also supported the control of two outbreaks of influenza A, which occurred in different centers in Miyagi Prefecture in the early period after the disaster. Both outbreaks subsided without any complicated or fatal cases of influenza as a result of the prompt implementation of a systemic approach with a bundle of control measures.

Background Clear cell sarcoma (CCS) is a therapeutically unresolved, aggressive, soft tissue sarcoma (STS) that predominantly affects young adults. This sarcoma is defined by t(12;22)(q13;q12) translocation, which leads to the fusion of Ewing sarcoma gene (EWS) to activating transcription factor 1 (ATF1) gene, producing a chimeric EWS-ATF1 fusion gene. We established a novel CCS cell line called Hewga-CCS and developed an orthotopic tumor xenograft model to enable comprehensive bench-side investigation for intensive basic and preclinical research in CCS with a paucity of experimental cell lines. Methods Hewga-CCS was derived from skin metastatic lesions of a CCS developed in a 34-year-old female. The karyotype and chimeric transcript were analyzed. Xenografts were established and characterized by morphology and immunohistochemical reactivity. Subsequently, the antitumor effects of pazopanib, a recently approved, novel, multitargeted, tyrosine kinase inhibitor (TKI) used for the treatment of advanced soft tissue sarcoma, on Hewga-CCS were assessed in vitro and in vivo. Results Hewga-CCS harbored the type 2 EWS-ATF1 transcript. Xenografts morphologically mimicked the primary tumor and expressed S-100 protein and antigens associated with melanin synthesis (Melan-A, HMB45). Pazopanib suppressed the growth of Hewga-CCS both in vivo and in vitro. A phospho-receptor tyrosine kinase array revealed phosphorylation of c-MET, but not of VEGFR, in Hewga-CCS. Subsequent experiments showed that pazopanib exerted antitumor effects through the inhibition of HGF/c-MET signaling. Conclusions CCS is a rare, devastating disease, and our established CCS cell line and xenograft model may be a useful tool for further in-depth investigation and understanding of the drug-sensitivity mechanism.

Leishmaniasis consists of a complex spectrum of infectious diseases with worldwide distribution of which visceral leishmaniasis or kala-azar caused by Leishmania donovani is the most devastating. In the absence of vaccines, chemotherapy remains the mainstay for the control of leishmaniasis. The drugs of choice are expensive and associated with multiple adverse side effects. Because of these limitations, the development of new antileishmanial compounds is imperative and plants offer prospects in this regard. The present work was conducted to study the antileishmanial potential of oil from Syzygium aromaticum flower buds (clove). The S. aromaticum oil was characterized by gas chromatography and GC-MS and eugenol as well as eugenyl acetate were found to be the most abundant compounds, composing 59.75 % and 29.24 %, respectively of the oil. Our findings have shown that eugenol-rich essential oil from S. aromaticum (EROSA) possesses significant activity against L. donovani, with 50 % inhibitory concentration of 21 ± 0.16 µg ml(-1) and 15.24 ± 0.14 µg ml(-1), respectively, against promastigotes and intracellular amastigotes. Alterations in cellular morphology and growth reversibility assay substantiated the leishmanicidal activity of EROSA. The leishmanicidal effect was mediated via apoptosis as confirmed by externalization of phosphatidylserine, DNA nicking by TdT-mediated dUTP nick-end labelling (TUNEL) assay, dyskinetoplastidy, cell cycle arrest at sub-G0-G1 phase, loss of mitochondrial membrane potential and reactive oxygen species generation. EROSA presented no adverse cytotoxic effects against murine macrophages even at 200 µg ml(-1). Our studies authenticate the promising antileishmanial activity of EROSA, which is mediated by programmed cell death, and, accordingly, EROSA may be a source of novel agents for the treatment of leishmaniasis.

Diabetic polyneuropathy (DPN) is a devastating complication of diabetes. The underlying pathogenesis of DPN is still elusive and an effective treatment devoid of side effects presents a challenge. There is evidence that in type-1 and -2 diabetes, metabolic and morphological changes lead to peripheral nerve damage and altered central nociceptive transmission, which may contribute to neuropathic pain symptoms. We characterized the electrophysiological response properties of spinal wide dynamic range (WDR) neurons in three diabetic models. The streptozotocin (STZ) model was used as a drug-induced model of type-1 diabetes, and the BioBreeding/Worcester (BB/Wor) and Zucker diabetic fatty (ZDF) rat models were used for genetic DPN models. Data were compared to the respective control group (BB/Wor diabetic-resistant, Zucker lean (ZL) and saline-injected Wistar rat). Response properties of WDR neurons to mechanical stimulation and spontaneous activity were assessed. We found abnormal response properties of spinal WDR neurons in all diabetic rats but not controls. Profound differences between models were observed. In BB/Wor diabetic rats evoked responses were increased, while in ZDF rats spontaneous activity was increased and in STZ rats mainly after discharges were increased. The abnormal response properties of neurons might indicate differential pathological, diabetes-induced, changes in spinal neuronal transmission. This study shows for the first time that specific electrophysiological response properties are characteristic for certain models of DPN and that these might reflect the diverse and complex symptomatology of DPN in the clinic.

Cancer is a devastating disease and a large socio-economic burden. Novel therapeutic solutions are on the rise, although a cure remains elusive. Application of microorganisms represents an ancient therapeutic strategy, lately revoked and refined via simultaneous attenuation and amelioration of pathogenic properties. Salmonella Typhimurium has prevailed in preclinical development. Yet, using virulent strains for systemic treatment might cause severe side effects. In the present study, we highlight a modified strain based on Salmonella Typhimurium UK-1 expressing hexa-acylated Lipid A. We corroborate improved anti-tumor properties of this strain and investigate to which extent an intra-tumoral (i.t.) route of infection could help improve safety and retain advantages of systemic intravenous (i.v.) application. Our results show that i.t. infection exhibits therapeutic efficacy against CT26 and F1.A11 tumors similar to a systemic route of inoculation. Moreover, i.t. application allows extensive dose titration without compromising tumor colonization. Adverse colonization of healthy organs was generally reduced via i.t. infection and accompanied by less body weight loss of the murine host. Despite local application, adjuvanticity remained, and a CT26-specific CD8+ T cell response was effectively stimulated. Most interestingly, also secondary tumors could be targeted with this strategy, thereby extending the unique tumor targeting ability of Salmonella. The i.t. route of inoculation may reap the benefits of systemic infection and aid in safety assurance while directing potency of an oncolytic vector to where it is most needed, namely the primary tumor.

While antipsychotic medications provide important relief from debilitating psychotic symptoms, they also have significant adverse side effects, which might have relevant impact on human health. Several research studies, including ours, have shown that commonly used antipsychotics such as haloperidol and aripiprazole affect cholesterol biosynthesis at the conversion of 7-dehydrocholesterol (7-DHC) to cholesterol. This transformation is promoted by the enzyme DHCR7 and its inhibition causes increases in plasma and tissue levels of 7-DHC. The inhibition of this enzymatic step by mutations in the Dhcr7 gene leads to Smith-Lemli-Opitz syndrome, a devastating human condition that can be replicated in rats by small molecule inhibitors of DHCR7. The fact that two compounds, brexpiprazole and cariprazine, that were recently approved by the FDA have substructural elements in common with the DHCR7 inhibitor aripiprazole, prompted us to evaluate the effect of brexpiprazole and cariprazine on cholesterol biosynthesis. We report that cariprazine affects levels of 7-DHC and cholesterol in cell culture incubations at concentrations as low as 5 nM. Furthermore, a common metabolite of cariprazine and aripiprazole, 2,3-(dichlorophenyl) piperazine, inhibits DHCR7 activity at concentrations comparable to those of the potent teratogen AY9944. The cell culture experiments were corroborated in mice in studies showing that treatment with cariprazine elevated 7-DHC in brain and serum. The consequences of sterol inhibition by antipsychotics in the developing nervous system and the safety of their use during pregnancy remains to be established. Copyright © 2018 Elsevier Inc.

HIV/AIDS has had a devastating impact at individual, household and community levels. This qualitative research investigates the role of HIV voluntary counselling and testing (VCT) and treatment in enabling HIV-positive Ugandans to cope with this disease. Twelve predetermined focus group discussions (FGDs) were conducted; six with men and six with women. Half of the men and women's groups were receiving antiretroviral therapy (ART) and half were not. An FGD was held with the health care providers administering ART. Testing for HIV was perceived as soliciting a death warrant. Participants affirmed that the incentive for testing was the possibility of accessing free ART. They described experiencing gender-variant stigma and depression on confirming their HIV status and commended the role of counselling in supporting them to adopt positive living. For those receiving ART, counselling reinforced treatment adherence. The findings also revealed gender differences in treatment adherence strategies. ART was described to reduce disease symptoms and restore physical health allowing them to resume their daily activities. Additionally, ART was preferred over traditional herbal treatment because it had clear dosages, expiry dates and was scientifically manufactured. Those that were not receiving ART bore myths and misconceptions about the effectiveness and side effects of ART, delaying the decision to seek treatment. Stigma and the attached concern of HIV/AIDS-related swift death, is a major barrier for VCT. Based on this study's findings, ensuring the provision of quality assured and gender conscious VCT and ART delivery services will enhance positive living and enforce compliance to ART programmes.

Consortium for Earthquake-Damaged Cultural Heritage (CEDACH) is a voluntary initiative launched just after the Great East Japan Earthquake on 11 March 2011. The consortium is developing a social network between local cultural resource managers restoring disaster-damaged cultural heritage on one side and remote researchers including historians, archaeologists and specialists of cultural information studies on the other side, in order to facilitate collaborative projects. This paper presents three projects in which CEDACH contributed to the development of a digital inventory for disaster-damaged heritage management through web-based collaborations by self-motivated workers. The first project, CEDACH GIS, developed an online archaeological site inventory for the disaster area. Although a number of individuals voluntarily participated in the project at the beginning, it gradually stagnated due to limited need for local rescue archaeology. However, the experience of online-based collaborations worked well for the second project proposed by local specialists, in which CEDACH restored the book catalogue of a tsunami-devastated research library. This experience highlighted the need for online education to improve information and communication technologies (ICT) skills of data builders. Therefore, in the third project called CEDACHeLi, an e-Learning management system was developed to facilitate learning the fundamental knowledge and techniques required for information processing in rescue operations of disaster-damaged cultural heritage. This system will contribute to improved skills and motivation of potential workers for further developments in digital heritage inventory.

What gives an organism the ability to regrow tissues and to recover function where another organism fails is the central problem of regenerative biology. The challenge is to describe the mechanisms of regeneration at the molecular level, delivering detailed insights into the many components that are cross-regulated. In other words, a broad, yet deep dissection of the system-wide network of molecular interactions is needed. Functional genomics has been used to elucidate gene regulatory networks (GRNs) in developing tissues, which, like regeneration, are complex systems. Therefore, we reason that the GRN approach, aided by next generation technologies, can also be applied to study the molecular mechanisms underlying the complex functions of regeneration. We ask what characteristics a model system must have to support a GRN analysis. Our discussion focuses on regeneration in the central nervous system, where loss of function has particularly devastating consequences for an organism. We examine a cohort of cells conserved across all vertebrates, the reticulospinal (RS) neurons, which lend themselves well to experimental manipulations. In the lamprey, a jawless vertebrate, there are giant RS neurons whose large size and ability to regenerate make them particularly suited for a GRN analysis. Adding to their value, a distinct subset of lamprey RS neurons reproducibly fail to regenerate, presenting an opportunity for side-by-side comparison of gene networks that promote or inhibit regeneration. Thus, determining the GRN for regeneration in RS neurons will provide a mechanistic understanding of the fundamental cues that lead to success or failure to regenerate.
A unified frame of predicting side effects of drugs by using linear neighborhood similarity.

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.

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

Detection of 'Candidatus Liberibacter asiaticus' represents one of the most difficult, yet critical, steps of controlling Huanglongbing disease. Efficient detection relies on understanding the underlying distribution of bacteria within trees. To that end, we studied the distribution of 'Ca. L. asiaticus' in leaves of 'Rio Red' grapefruit trees and in roots of 'Valencia' sweet orange trees grafted onto sour orange rootstock. We performed two sets of leaf collection on grapefruit trees; the first a selective sampling targeting symptomatic leaves and their neighbors and the second a systematic collection disregarding symptomology. From uprooted orange trees, we exhaustively sampled fibrous roots. In this study, the presence of 'Ca. L. asiaticus' was detected in leaves using real-time polymerase chain reaction (PCR) targeting the 16S ribosomal gene and in roots using the rpIJ/rpIL ribosomal protein genes and was confirmed with conventional PCR and sequencing of the rpIJ/rpIL gene in both tissues. Among randomly collected leaves, 'Ca. L. asiaticus' was distributed in a patchy fashion. Detection of 'Ca. L. asiaticus' varied with leaf symptomology with symptomatic leaves showing the highest frequency (74%) followed by their neighboring asymptomatic leaves (30%), while randomly distributed asymptomatic leaves had the lowest frequency (20%). Among symptomatic leaves, we found statistically significant differences in mean number of bacterial cells with respect to both increasing distance of the leaf from the trunk and cardinal direction. The titer of 'Ca. L. asiaticus' cells was significantly greater on the north side of trees than on the south and west sides. Moreover, these directions showed different spatial distributions of 'Ca. L. asiaticus' with higher titers near the trunk on the south and west sides as opposed to further from the trunk on the north side. Similarly, we found spatial variation in 'Ca. L. asiaticus' distribution among root samples. 'Ca. L. asiaticus' was detected more frequently and bacterial abundances were higher among horizontally growing roots just under the soil surface (96%) than among deeper vertically growing roots (78%). Bacterial abundance declined slightly with distance from the trunk. These results point to paths of research that will likely prove useful to combating this devastating disease.
Side effects associated with anti-HIV drugs.
Highleyman, L
1998-04-01
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.

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.

Cultures meet and apparently insignificant traits or objects disrupt one of the cultures. This process repeatedly occurred in history with devastating consequences for the affected groups. Personal health, sanity, societies and cultures suffered from the effects of the new intrusions. Insights from sociological theory shed light on the effects and suggest remedies for at least some of the dysfunctions. Strategies for understanding and handling unforeseen changes must be prepared for future contact with other intelligences.

Effect of Economic Assets on Sexual Risk-Taking Intentions Among Orphaned Adolescents in Uganda
Han, Chang-Keun; Neilands, Torsten B.; Ismayilova, Leyla; Sperber, Elizabeth
2010-01-01
Objectives. We examined the effect of economic assets on sexual risk-taking intentions among school-going AIDS-orphaned adolescents in rural Uganda. Methods. AIDS-orphaned adolescents from 15 comparable schools were randomly assigned to control (n = 133) or treatment (n = 127) conditions. Treatment participants received child savings accounts, workshops, and mentorship. This economic intervention was in addition to the traditional care and support services for school-going orphaned adolescents (counseling and school supplies) provided to both treatment and control groups. Adolescents in the treatment condition were compared with adolescents in the control condition at baseline and at 10 months after the intervention. Results. After control for sociodemographic factors, child-caregiver/parental communication, and peer pressure, adolescents in the economic intervention group reported a significant reduction in sexual risk-taking intentions compared with adolescents in the control condition. Conclusions. The findings indicate that in Uganda, a country devastated by poverty and disease (including HIV/AIDS), having access to economic assets plays an important role in influencing adolescents' sexual risk-taking intentions. These findings have implications for the care and support of orphaned adolescents, especially in poor African countries devastated by poverty and sexually transmitted diseases. PMID:20075323
Effect of Communication Style on Perceptions of Medication Side Effect Risk among Pharmacy Students.

2016-10-25
Objective. To assess the effect of communication style, and frequency and severity of medication side-effects, on pharmacy students' perception of risk of experiencing side effects. Methods. One hundred responses from pharmacy students were obtained using an online survey. Participants were presented with a drug information box containing drug name, drug usage, and one side-effect associated with the drug. Information on side-effect for each drug was presented in one of eight experimental conditions, in a 2 (side-effect frequency: low, high), X2 (side-effect severity: mild, severe) X2 (communication style: verbal, verbal + natural frequency) factorial design. Risk perception of experiencing side effects was measured. Results. Communication style was found to have a significant impact on risk perception depending on the context of frequency and severity associated with the side effect. Conclusion. Communication style plays a significant role in formulating risk perceptions of medication side effects. Training in pharmaceutical counseling should include special emphasis on effective language use.

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.
Explanations for side effect aversion in preventive medical treatment decisions

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

Paraplegia following spinal cord ischemia represents a devastating complication of both aortic surgery and endovascular aortic repair. Shock wave treatment was shown to induce angiogenesis and regeneration in ischemic tissue by modulation of early inflammatory response via Toll-like receptor (TLR) 3 signaling. In preclinical and clinical studies, shock wave treatment had a favorable effect on ischemic myocardium. We hypothesized that shock wave treatment also may have a beneficial effect on spinal cord ischemia. A spinal cord ischemia model in mice and spinal slice cultures ex vivo were performed. Treatment groups received immediate shock wave therapy, which resulted in decreased neuronal degeneration and improved motor function. In spinal slice cultures, the activation of TLR3 could be observed. Shock wave effects were abolished in spinal slice cultures from TLR3(-/-) mice, whereas the effect was still present in TLR4(-/-) mice. TLR4 protein was found to be downregulated parallel to TLR3 signaling. Shock wave-treated animals showed significantly better functional outcome and survival. The protective effect on neurons could be reproduced in human spinal slices. Shock wave treatment protects from neuronal degeneration via TLR3 signaling and subsequent TLR4 downregulation. Consequently, it represents a promising treatment option for the devastating complication of spinal cord ischemia after aortic repair. © 2015 The Authors.

Poisonous plants have a devastating impact on the livestock industry as well as human health. To fully understand the effects of poisonous plants, multiple scientific disciplines are required. Chemical analysis of plant secondary compounds is key to identifying the responsible toxins, characterizing their metabolism, and understanding their effects on animals and humans. In this review, we highlight some of the successes in studying poisonous plants and mitigating their toxic effects. We also highlight some of the remaining challenges and opportunities with regards to the chemical analysis of poisonous plants.

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.

The emergence of outbreaks of Zika virus (ZIKV) in Brazil in 2015 was associated with devastating effects on fetal development and prompted a world health emergency and multiple efforts to generate an effective vaccine against infection. There are now more than 40 vaccine candidates in preclinical development and six in clinical trials. Despite similarities with other flaviviruses to which successful vaccines have been developed, such as yellow fever virus and Japanese Encephalitis virus, there are unique challenges to the development and clinical trials of a vaccine for ZIKV.

Significance of the breast to the individual and society.
Spencer, K W
1996-01-01
The breast is the most important external identification of femininity, and the loss of a breast can have devastating psychological effects on a woman. A woman who has lost a breast through cancer may feel self-conscious, insecure, inferior to other women, or undesirable to men. These body image concerns are key reasons why a woman will be motivated to pursue breast reconstruction.

Extensive Burn Scars in Russia's Amur Region
NASA Technical Reports Server (NTRS)
2002-01-01
Vast areas of southeastern Russia have been scorched by fires over the last few weeks. All across Siberia fires have been raging, and this Moderate Resolution Imaging Spectroradiometer (MODIS) image from May 15, 2002, shows extensive, dark burn scars along with actively burning fires (red dots) on the north side of the Amur River, which separates Russia (north) and China (south). The southern Amur region is largely devoted to farming and other agriculture, and these fires may have been set intentionally to prepare the land for the growing season. Fire is often used to clear land of unwanted vegetation, and to return the nutrients stored in vegetation back to the soil. However, fires that are too frequent or severe can devastate the soil, eventually making it unsuitable for farming or grazing. Fires can also escape control and spread into protected areas. In this image, fires are mostly concentrated in a lowland area within the drainage basin of the Zeya River, which drains from the frozen lake at the top of the image.

A 69-year-old woman was admitted to our hospital because of a sudden severe headache without a history of head trauma. CT and MRI revealed an acute subdural hematoma (ASDH) extending from the right interhemispheric space to the posterior fossa bilaterally, with a small amount of subarachnoid hemorrhage that was predominantly localized to the left side of the basal cistern. CT angiogram demonstrated a long protruding ruptured aneurysm at the junction of the right internal carotid and posterior communicating arteries (IC/PC AN) with a posteroinferior projection, associated with a small bleb located near the tentorial edge close to the ipsilateral posterior clinoid process, for which she received clipping surgery. Though rare, IC/PC AN could cause pure or nearly pure ASDH in the above-mentioned distribution. Therefore, in patients with such ASDH, especially without a history of head injury or precise information regarding the situation at the time of onset, urgent imaging evaluation and early intervention are essential to prevent devastating re-rupture events.
Traumatic symptomatology in children who witness marital violence.

For many years, research has demonstrated the devastating effects of violence upon children, particularly in the form of direct physical and sexual abuse. What has only recently come to into focus are the potential effects of witnessing violence upon children. This area of vicarious victimization seems of particular import given the fact that so many youngsters are known to witness violent acts within their own households. This paper shall review the psychological effects which may be effected upon children as a result of witnessing marital violence. Relevant research issues concerning the potential roles of moderating and mediating variables will also be discussed.

Schizophrenia is one of the most debilitating psychiatric diseases with a lifetime prevalence of approximately 1%. Although the specific molecular underpinnings of schizophrenia are still unknown, evidence has long linked its pathophysiology to postsynaptic abnormalities. The postsynaptic density (PSD) is among the molecular structures suggested to be potentially involved in schizophrenia. More specifically, the PSD is an electron-dense thickening of glutamatergic synapses, including ionotropic and metabotropic glutamate receptors, cytoskeletal and scaffolding proteins, and adhesion and signaling molecules. Being implicated in the postsynaptic signaling of multiple neurotransmitter systems, mostly dopamine and glutamate, the PSD constitutes an ideal candidate for studying dopamine-glutamate disturbances in schizophrenia. Recent evidence suggests that some PSD proteins, such as PSD-95, Shank, and Homer are implicated in severe behavioral disorders, including schizophrenia. These findings, further corroborated by genetic and animal studies of schizophrenia, offer new insights for the development of pharmacological strategies able to overcome the limitations in terms of efficacy and side effects of current schizophrenia treatment. Indeed, PSD proteins are now being considered as potential molecular targets against this devastating illness. The current paper reviews the most recent hypotheses on the molecular mechanisms underlying schizophrenia pathophysiology. First, we review glutamatergic dysfunctions in schizophrenia and we provide an update on postsynaptic molecules involvement in schizophrenia pathophysiology by addressing both human and animal studies. Finally, the possibility that PSD proteins may represent potential targets for new molecular interventions in psychosis will be discussed. PMID:24851087
Hair and cancer chemotherapy: consequences and nursing care--a literature study.
Batchelor, D
2001-09-01
Hair is a body appendage that throughout history has been a symbol of the social, cultural and political climate, in addition to connoting religious affiliation. Hair loss on the other hand has been associated with a loss of attractiveness, individuality, a state of disgrace and illness, in addition to the ageing process, death and a loss of sexuality. One of the most common side-effects of chemotherapy is hair loss (alopecia). Alopecia can range from sporadic thinning of the hair to complete baldness. Several factors may contribute to the severity of hair loss including drug, dose and schedule as well as hair care practices. Prevention of alopecia has been a focus in the medical and nursing literature since the late 1960s. Mechanical, physical and biological measures have been used with varying success. The goal of prevention is primarily the reduction of patient distress caused by chemotherapy-induced alopecia. Patient reactions to alopecia vary and may be dependent on the individual importance of hair, prognosis, degree of expected hair loss, the amount of information and preparation given, and physical and psychological coping mechanisms. Nurses play an important role in assisting the patient to cope with alopecia by giving the needed information and teaching self-care strategies to minimize alopecia, cope with alopecia, and protect the skin and eyes following alopecia. These interventions are aimed at helping the patient move through a potentially devastating experience to a renewed sense of well-being.
Surgery for portal hypertension in children: A 12-year review.

2017-11-06
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.

Therapeutic advances do not circumvent the devastating fact that the survival rate in glioblastoma multiforme (GBM) is less than 5%. Nanoparticles consisting of liposome-based therapeutics are provided against a variety of cancer types including GBM, but available liposomal formulations are provided without targeting moieties, which increases the dosing demands to reach therapeutic concentrations with risks of side effects. We prepared PEGylated immunoliposomes (ILs) conjugated with anti-human epidermal growth factor receptor (EGFR) antibodies Cetuximab (α-hEGFR-ILs). The affinity of the α-hEGFR-ILs for the EGF receptor was evaluated in vitro using U87 mg and U251 mg cells and in vivo using an intracranial U87 mg xenograft model. The xenograft model was additionally analyzed with respect to permeability to endogenous albumin, tumor size, and vascularization. The in vitro studies revealed significantly higher binding of α-hEGFR-ILs when compared with liposomes conjugated with isotypic nonimmune immunoglobulin. The uptake and internalization of the α-hEGFR-ILs by U87 mg cells were further confirmed by 3D deconvolution analyses. In vivo, the α-hEGFR-ILs accumulated to a higher extent inside the tumor when compared to nonimmune liposomes. The data show that α-hEGFR-ILs significantly enhance the uptake and accumulation of liposomes in this experimental model of GBM suggestive of improved specific nanoparticle-based delivery.

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.

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.

Despite the availability of new antiretroviral drugs and the simplification of treatment options, side effects continue to affect people living with HIV. In this paper, we present the findings of a grounded theory study designed to gain a critical understanding of the experience of side effects. Three main categories emerged from the data: the side effects, the experience, and the connections. The first category suggests that we need to change how we think about side effects in order to take into account the context in which they are experienced as well as the types and nature of side effects. The second category puts forward the idea that the experience of side effects is composed of three interrelated processes: becoming with, living with, and dealing with. Finally, the third category points to new connections that are formed with people, things and systems in the presence of side effects. PMID:27867446

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.

Diffuse Intrinsic Pontine Gliomas (DIPG) are the most devastating of all pediatric brain tumors. They mostly affect young children and, as there are no effective treatments, almost all patients with DIPG will die of their tumor within 12 months of diagnosis. A key feature of this devastating tumor is its intrinsic resistance to all clinically available therapies. It has been shown that glioma development is associated with metabolic reprogramming, redox state disruption and resistance to apoptotic pathways. The mitochondrion is an attractive target as a key organelle that facilitates these critical processes. PENAO is a novel anti-cancer compound that targets mitochondrial function by inhibiting adenine nucleotide translocase (ANT). Here we found that DIPG neurosphere cultures express high levels of ANT2 protein and are sensitive to the mitochondrial inhibitor PENAO through oxidative stress, while its apoptotic effects were found to be further enhanced upon co-treatment with mTOR inhibitor temsirolimus. This combination therapy was found to act through inhibition of PI3K/AKT/mTOR pathway, HSP90 and activation of AMPK. In vivo experiments employing an orthotopic model of DIPG showed a marginal anti-tumour effect likely due to poor penetration of the inhibitors into the brain. Further testing of this anti-DIPG strategy with compounds that penetrate the BBB is warranted. PMID:29484131

Sarcopenia - or the loss of muscle mass, strength and function with ageing - represents an important health issue of the twenty-first century because of its devastating effects in addition to an increased prevalence of aged people. The devastating health effects of sarcopenia are multiple: an increased falls risk, a decreased physical ability and quality of life and an independent increase of all-cause mortality. Although the ultimate remedy for sarcopenia yet has to be found, some interventions have proven their merit and might be of practical use in clinical practice, especially for geriatricians, who deal most with sarcopenia. This review intends to summarize the current therapeutic interventions, their proposed mechanism of action as well as their clinical value. The results of our review highlight the importance of exercise (50% resistance training, 50% endurance training), nutrition (25-30 g proteins with essential amino acids every meal and long-chain ω-3 fatty acids) and limitation of alcohol and smoking. In addition, studies also suggest a place for vitamin D (aim serum levels >30 ng/L), testosterone (aim serum levels >300 ng/dL) and creatine (15-20 g/d for five days, thereafter 3-5 g/d). In conclusion, although more studies are needed to elucidate the exact effectiveness and safety of many sarcopenia interventions, the current evidence already provides clinically useful information, which might benefit the patient with (pre-)sarcopenia.

Fungal plant pathogens are major threats to food security worldwide. Sclerotinia sclerotiorum and Botrytis cinerea are closely related Ascomycete plant pathogens causing mold diseases on hundreds of plant species. There is no genetic source of complete plant resistance to these broad host range pathogens known to date. Instead, natural plant populations show a continuum of resistance levels controlled by multiple genes, a phenotype designated as quantitative disease resistance. Little is known about the molecular mechanisms controlling the interaction between plants and S. sclerotiorum and B. cinerea but significant advances were made on this topic in the last years. This minireview highlights a selection of nine themes that emerged in recent research reports on the molecular bases of plant-S. sclerotiorum and plant-B. cinerea interactions. On the fungal side, this includes progress on understanding the role of oxalic acid, on the study of fungal small secreted proteins. Next, we discuss the exchanges of small RNA between organisms and the control of cell death in plant and fungi during pathogenic interactions. Finally on the plant side, we highlight defense priming by mechanical signals, the characterization of plant Receptor-like proteins and the hormone abscisic acid in the response to B. cinerea and S. sclerotiorum, the role of plant general transcription machinery and plant small bioactive peptides. These represent nine trends we selected as remarkable in our understanding of fungal molecules causing disease and plant mechanisms associated with disease resistance to two devastating broad host range fungi.

In order to reliably assess tsunami hazard in eastern Indonesia, we need to understand how historical events were generated. Here we consider two such events: the 1674 Ambon and the 1992 Flores tsunamis. Firstly, Ambon Island suffered a devastating earthquake that generated a tsunami with 100 m run-up height on the north coast of the island in 1674. However, there is no known active fault around the island capable of generating such a gigantic wave. Rumphius' report describes that the initial wave was coming from three villages that collapsed immediately after the earthquake with width as far as a musket shot. Moreover, a very high tsunami was only observed locally. We suspect that a submarine landslide was the main cause of the gigantic tsunami on the north side of Ambon Island. Unfortunately, there is no data available to confirm if landslide have occurred in this region. Secondly, several tsunami source models for the 1992 Flores event have been suggested. However, the fault strike is quite different compare to the existing Flores back-arc thrust and has not been well validated against a tide gauge waveform at Palopo, Sulawesi. We considered a tsunami model based on Griffin, et al., 2015, extended with high resolution bathymetry laround Palopo, in order to validate the latest tsunami source model available. In general, the model produces a good agreement with tsunami waveforms, but arrives 10 minutes late compared to observed data. In addition, the source overestimates the tsunami inundation west of Maumere, and does not account for the presumed landslide tsunami on the east side of Flores Island.

Canakinumab in patients with cryopyrin-associated periodic syndrome: an update for clinicians
Haug, Iris
2013-01-01
The cryopyrin-associated periodic syndrome (CAPS) is a very rare disease. It is estimated that there are 1–2 cases for every 1 million people in the US and 1 in every 360,000 in France. However, many patients are diagnosed very late or not at all, meaning the real prevalence is likely to be higher. CAPS encompasses the three entities of familial cold auto-inflammatory syndrome (FCAS), Muckle–Wells syndrome (MWS), and neonatal-onset multisystem inflammatory disease (NOMID)/chronic infantile neurologic, cutaneous and articular (CINCA) syndrome. They have in common a causative mutation in the NLRP3 gene. The altered gene product cryopyrin leads to activation of the inflammasome which in turn is responsible for excessive production of interleukin (IL)-1β. IL-1β causes the inflammatory manifestations in CAPS. These appear as systemic inflammation including fever, headache or fatigue, rash, eye disease, progressive sensorineural hearing loss, musculoskeletal manifestations and central nervous system (CNS) symptoms (NOMID/CINCA only). With the advent of IL-1 Inhibitors, safe and effective therapeutic options became available for this devastating disease. To prevent severe and possible life-threatening disease sequelae, early and correct diagnosis and immediate initiation of therapy are mandatory in most patients. Canakinumab is a fully human monoclonal IgG1 anti-IL-1β antibody. It provides selective and prolonged IL-1β blockade and has demonstrated a rapid (within hours), complete and sustained response in most CAPS patients without any consistent pattern of side effects. Long-term follow-up trials have demonstrated sustained efficacy, safety and tolerability. Canakinumab is approved by the US Food and Drug Administration for FCAS and MWS and by European Medicines Agency for treatment of all three phenotypes of CAPS. PMID:24294305

To examine the effects of using positive or negative frames to describe influenza vaccine benefits and side effects on patients' expectations, decisions, decisional conflict, and reported side effects. 292 previously unimmunized patients with chronic respiratory or cardiac disease were randomly assigned to receive benefit/risk information that was framed: (1) positively as the percentage who remain free of influenza and have no vaccine side effects, or (2) negatively as the percentage who acquire influenza and have vaccine side effects. Questionnaires elicited expectations, decisions, and decisional conflict. Vaccines were telephoned 3 days later for a self-report of local and systemic side effects and work absenteeism. Both groups had similar immunization rates and decisional conflict scores. The positive frame group had lower and more realistic expectations of vaccine side effects, fewer systemic side effects, and less work absenteeism (p < 0.05). In contrast to previous studies of health care workers, framing did not influence patients' decisions, possibly due to the patients' awareness of their higher risk of influenza complications and greater desire to follow recommendations. The common practice of using negative frames when describing probabilities of side effects may need to be reexamined, considering its deleterious influence on self-reported side effects and work absenteeism.

Diabetes mellitus can cause devastating foot problems including loss of protective sensation with subsequent ulcerations and amputations. The natural history and pathophysiology of diabetic foot ulcers is best understood and managed by a multiprofessional team approach. The main factors for prevention and treatment of these devastating diabetic foot conditions are shown, with special attention to education of the patient. This approach decreases the morbidity of the disease, besides its economical and social feasibility. PMID:22396805

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.

Duchenne muscular dystrophy (DMD) is a devastating progressive disease for which there is currently no effective treatment except palliative therapy. There are several promising genetic approaches, including viral delivery of the missing dystrophin gene, read-through of translation stop codons, exon skipping to restore the reading frame and increased expression of the compensatory utrophin gene. The lessons learned from these approaches will be applicable to many other disorders.

A Comparison of Sexual Side Effects of Antidepressants With and Without Naltrexone.
Thapa, Mona; Petrakis, Ismene; Ralevski, Elizabeth
2017-01-01
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 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.

Background Epilepsy is a devastating disorder that impacts on patients’ quality of life, irrespective of use of anti epileptic drugs (AEDs). This study estimates the health-related quality of life (HRQOL) and its associated predictors among epilepsy patients receiving AEDs. Methods A total of 175 epilepsy patients already receiving AED for at least 3 months were randomly selected and interviewed from mental clinics at Mulago and Butabika national referral hospitals in Uganda between May - July 2011. A HRQOL index, the primary outcome, was constructed using items from Quality Of Life in Epilepsy Inventory (QOLIE-31) and the Hospital Anxiety and Depression Scale (HADS) questionnaires. The internal consistency and adequacy of these items was also computed using Cronbach's alpha and Kaiser-Meyer-Olkin tests. Partial correlations were used to evaluate the contribution of the health dimensions (mental, psychological, social, physical functioning and emotional well being) and, multiple linear regressions to determine factors independently associated with HRQOL. Results Just about half of the respondents (54%) were males, and nearly two thirds (62%) had received AEDs for at least 12 months. The average age was 26.6 years (SD = 11.1). The overall HRQOL mean score was 58 (SD = 13) on a scale of 0–100. The average scores of different dimensions or subscales ranged from 41 (physical) to 65 (psychological). At least three quarters (75%) of all subscales had good internal consistency and adequacy. The largest variations in the overall HRQOL were explained by social and mental functioning; each accounting for about 30% of the difference in the HRQOL but seizure control features explained a little (6%) variation. Factors negatively associated with HRQOL were poly-therapy (-1.16, p = 0.01) and frequency of seizures (-2.29, p = 0.00). Other factors associated with overall HRQOL included drug side effects, sex, marital status and education. Duration on AEDs was not a significant predictor of HRQOL. Conclusion The HRQOL for epilepsy patients on AEDs is very low. The predictors of low HRQOL were socio factors (marital status, education) and drug side effects, frequency of seizure, and type of therapy. PMID:24725904

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 heightened 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.

On 11 March 2011, an earthquake measuring 9.0 on the Richter scale off the northeast coast of Honshu Island, Japan, produced a devastating tsunami that destroyed many towns and villages near the coast in Iwate, Miyagi, and Fukushima prefectures. Miyagi Prefecture was the area most severely devastated by the tsunami, with extensive loss of life and property; hundreds of thousands of people lost their houses and were forced to move to evacuation areas. In the days and weeks following devastating natural disasters, the threat of infectious disease outbreak is high. Rapid diagnostic tests can be performed at or near the site of patient care and the tests were very useful in this disaster, because they enabled us to manage patients appropriately in the settings where medical resources were limited. Here we report actual cases where the rapid diagnostic tests for infectious diseases were useful in the patient management.

"There is a chain of connections": using syndemics theory to understand HIV treatment side effects.
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.
Patient-provider communication and hormonal therapy side effects in breast cancer survivors.
Lin, Jenny J; Chao, Jennifer; Bickell, Nina A; Wisnivesky, Juan P
2017-09-01
Side effects from hormonal therapy (HT) for breast cancer treatment occur frequently and are associated with worse quality of life and HT non-adherence. Whether improved patient-physician communication is associated with patients' reporting of side effects is unknown. We undertook this study to assess factors associated with women's reports of HT side effects. Between December 2012 and April 2013, we conducted a cross-sectional survey of breast cancer patients undergoing HT in an urban medical center. Descriptive statistics, univariate analyses, and multivariate analyses were used to evaluate associations. Of the 100 participants, 67% reported having HT side effects. However, when prompted, an additional 9% reported experiencing specific HT-related symptoms. Despite very high communication scores, one-third of participants reported they had not discussed side effects with providers. Multivariate analysis showed that after controlling for age, education, race, and medication beliefs, women who had difficulty asking providers for more information were more likely to report side effects (odds ratio 8.27, 95% confidence interval 1.01-69.88). Although HT side effects often occur and are bothersome, patient-provider discussions about side effects remain suboptimal. Providers should actively ask patients about medication side effects so that they can be addressed to improve quality of life and potentially, medication adherence.

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.

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.

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.

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.
Treatment factors affecting longitudinal quality of life in new onset pediatric epilepsy.
Modi, Avani C; Ingerski, Lisa M; Rausch, Joseph R; Glauser, Tracy A

Recognizing the importance of patient-reported outcomes, this longitudinal, prospective study examined: Changes in health-related quality of life (HRQOL) over seven months following antiepileptic drug (AED) initiation and the relationship of seizures, AED side-effects, and AED type to HRQOL. Parents of 124 children with newly diagnosed epilepsy completed measures of HRQOL and side-effects at each clinic visit. Treatment information was also collected. HRQOL remained stable over time; however, seizures and AED side-effects significantly affected multiple HRQOL domains. Higher seizure activity was associated with decreased Physical HRQOL. Side-effects were negatively associated with all HRQOL domains. Children taking carbamazepine who experienced higher side-effects early in therapy demonstrated declining emotional functioning compared to children experiencing no/some side-effects. AED side-effects, AED type, and seizure frequency were associated with longitudinal HRQOL in children with newly-diagnosed epilepsy. Routine assessment of AED side-effects and HRQOL may be useful for clinical decision making.
[Treatment side effects and compliance in patients with depression].
Petrova, N N; Kucher, E O
2012-01-01
The impact of treatment side-effects on the compliance was studied in 85 depressive patients with different mental disorders - recurrent depressive disorder, postschizophrenic depression and organic affective disorder. The comparison of objective and subjective evaluations of compliance and a comparative analysis of the level of compliance, with its dependence on the treatment specifics, in different diseases were done. A significant role of efficacy and treatment side-effects was identified. The levels of "mental" and "autonomous" side-effects were highest in the treatment of depression: patients with postschizophrenic depression had the highest risk in respect of maintenance treatment; patients with recurrent depressive disorder and organic (affective) disorder were more tolerant to the treatment side-effects and their treatment, including the maintenance therapy, was rather effective. The compliance of all patients with depression was negatively correlated with the severity of side-effects of pharmacotherapy. The greatest side-effects and the lowest level of compliance were observed in the complex treatment with antidepressants and atypical neuroleptics. The effect of side-effects on the compliance was dependent on their severity and subjective tolerability and, to a lesser extent, on the amount of drugs.

Facial palsy or paralysis (FP) is a symptom that loses voluntary muscles movement in one side of the human face, which could be very devastating in the part of the patients. Traditional methods are solely dependent to clinician's judgment and therefore time consuming and subjective in nature. Hence, a quantitative assessment system becomes apparently invaluable for physicians to begin the rehabilitation process; and to produce a reliable and robust method is challenging and still underway. We introduce a novel approach for a quantitative assessment of facial paralysis that tackles classification problem for FP type and degree of severity. Specifically, a novel method of quantitative assessment is presented: an algorithm that extracts the human iris and detects facial landmarks; and a hybrid approach combining the rule-based and machine learning algorithm to analyze and prognosticate facial paralysis using the captured images. A method combining the optimized Daugman's algorithm and Localized Active Contour (LAC) model is proposed to efficiently extract the iris and facial landmark or key points. To improve the performance of LAC, appropriate parameters of initial evolving curve for facial features' segmentation are automatically selected. The symmetry score is measured by the ratio between features extracted from the two sides of the face. Hybrid classifiers (i.e. rule-based with regularized logistic regression) were employed for discriminating healthy and unhealthy subjects, FP type classification, and for facial paralysis grading based on House-Brackmann (H-B) scale. Quantitative analysis was performed to evaluate the performance of the proposed approach. Experiments show that the proposed method demonstrates its efficiency. Facial movement feature extraction on facial images based on iris segmentation and LAC-based key point detection along with a hybrid classifier provides a more efficient way of addressing classification problem on facial palsy type and degree of severity. Combining iris segmentation and key point-based method has several merits that are essential for our real application. Aside from the facial key points, iris segmentation provides significant contribution as it describes the changes of the iris exposure while performing some facial expressions. It reveals the significant difference between the healthy side and the severe palsy side when raising eyebrows with both eyes directed upward, and can model the typical changes in the iris region.
Exploring the associations between drug side-effects and therapeutic indications.

Drug therapeutic indications and side-effects are both measurable patient phenotype changes in response to the treatment. Inferring potential drug therapeutic indications and identifying clinically interesting drug side-effects are both important and challenging tasks. Previous studies have utilized either chemical structures or protein targets to predict indications and side-effects. In this study, we compared drug therapeutic indication prediction using various information including chemical structures, protein targets and side-effects. We also compared drug side-effect prediction with various information sources including chemical structures, protein targets and therapeutic indication. Prediction performance based on 10-fold cross-validation demonstrates that drug side-effects and therapeutic indications are the most predictive information source for each other. In addition, we extracted 6706 statistically significant indication-side-effect associations from all known drug-disease and drug-side-effect relationships. We further developed a novel user interface that allows the user to interactively explore these associations in the form of a dynamic bipartitie graph. Many relationship pairs provide explicit repositioning hypotheses (e.g., drugs causing postural hypotension are potential candidates for hypertension) and clear adverse-reaction watch lists (e.g., drugs for heart failure possibly cause impotence).

One of the major factors contributing to parental refusal of vaccinations is the perception that vaccines cause side effects. Although symptoms are commonly reported following vaccinations, their causes are not always straightforward. Although some may be directly attributable to the vaccine itself, others may reflect pre-existing or coincidental symptoms that are misattributed to the vaccine. To investigate psychological factors associated with parental report of side effects following vaccination with the child influenza vaccine, and parental intention to re-vaccinate one's child the following year. A prospective cohort study was run in primary care practices in London in the 2016-2017 influenza season (ClinicalTrials.gov number NCT02909855). Two hundred seventy parents from 14 practices completed a questionnaire before their child's vaccination. Follow-up questionnaires were completed 3 days after vaccination and one month after vaccination. Parental report of side effects and vaccination intention for the subsequent year were measured. Parental report of side effects was strongly associated with pre-vaccination expectation of side effects. Suggestions received from the media, National Health Service (NHS) vaccination leaflet, and health care workers, as well as uncertainty-related beliefs, perceived sensitivity of the child to medicines, pessimism, and anxiety were also associated with reporting side effects. Side effect report was associated with lower vaccination intention for the following influenza season. Side effect perception following vaccination is influenced by psychological factors, in particular expectations. Perceiving side effects reduces future vaccination intention. Future public health communications should aim to decrease unrealistic expectations of side effects to increase vaccine uptake.

Drug side effects cause a significant clinical and economic burden. However, mechanisms of drug action underlying side effect pathogenesis remain largely unknown. Here, we integrate pharmacogenomic and clinical data with a human metabolic network and find that non-pharmacokinetic metabolic pathways dysregulated by drugs are linked to the development of side effects. We show such dysregulated metabolic pathways contain genes with sequence variants affecting side effect incidence, play established roles in pathophysiology, have significantly altered activity in corresponding diseases, are susceptible to metabolic inhibitors and are effective targets for therapeutic nutrient supplementation. Our results indicate that metabolic dysregulation represents a common mechanism underlying side effect pathogenesis that is distinct from the role of metabolism in drug clearance. We suggest that elucidating the relationships between the cellular response to drugs, genetic variation of patients and cell metabolism may help managing side effects by personalizing drug prescriptions and nutritional intervention strategies.

Missing samples within synthetic aperture radar data result in image distortions. For coherent data products, such as coherent change detection and interferometric processing, the image distortion can be devastating to these second order products, resulting in missed detections and inaccurate height maps. Earlier approaches to repair the coherent data products focus upon reconstructing the missing data samples. This study demonstrates that reconstruction is not necessary to restore the quality of the coherent data products.

There are an increasing number of nursing academic administrators who identify themselves as victims of faculty incivility. This study examined experiences that academic administrators encountered with faculty incivility using a phenomenological research design. Three major themes emerged: faculty inappropriate behaviors, consequences of faculty behaviors on administrator targets, and administrators call for action. Findings revealed that incivility had devastating effects on administrators personally and professionally.

There is increasing concern among primary care practitioners about the use of opioids for chronic pain, including their adverse effects, but little attention has been given to how reports of side effects from prescription medication can contribute to outcomes among patients with chronic pain. The aim of this study was to investigate the impact of frequently reported side effects on mood, disability, and opioid misuse in patients with chronic pain prescribed opioids within primary care. Two hundred (N = 200) patients with chronic pain taking opioids for pain were recruited into the study. All patients completed baseline measures and a monthly side effects checklist once a month for 6 months. Patients were divided evenly based on a median split of the number of endorsed side effects over 6 months. The subjects repeated the baseline measures at the end of the study period. Over time, reports of medication side effects tended to decrease, but differences in frequency of reported side effects from baseline to follow-up (6-month time) were not significant, and the order of the frequency of the reported side effects remained similar. Patients who reported significant medication-related adverse effects reported significantly greater activity interference, negative affect, and catastrophizing compared with those with fewer side effects ( P < 0.01). In addition, those patients with pain who reported more side effects showed significantly higher scores on opioid misuse risk ( P < 0.001). This study demonstrates the important role of monitoring medication-related side effects among patients with chronic pain who are prescribed opioid medication for pain within primary care.

Side effects of low-dose pyridostigmine bromide are not related to cholinesterase inhibition.

Pretreatment with pyridostigmine bromide (PB) has become part of standard military procedures for protection against the effects of possible chemical warfare attack. The purpose of the work reported here was to quantify the type, intensity and frequency of side effects of low-dose PB, and to examine factors that predict the intensity and frequency of side effects. A double-blind, cross-over, placebo (PL)-controlled design was used. Of the 67 subjects, 33 received 30 mg PB every 8 h for 13 doses, and 34 received 60 mg on the same schedule. Order of PB and PL administration was counterbalanced. Overall, side effects were mild, even at the 60-mg dose level. More side effects were reported when volunteers were taking PB than when they were taking placebo. Women reported more symptoms than men. Neither cholinesterase inhibition nor plasma levels of PB predicted side effect scores during the PB week; the best predictor of side effect scores during the PB week was side effect scores during the PL week. PB is well tolerated by healthy young people, even when twice the recommended military dose is administered.

Analysis of relative importance of side effects of anticancer therapy is extremely useful in the process of clinical decision making. There is evidence that patients' perception of the side effects of anticancer treatments changes over time. Aim of this study was to evaluate the cancer patients' perceptions of physical and non-physical side effects of contemporary anticancer therapy. Four hundred and sixty-four patients entered the study (153 men and 311 women). Participants were asked to rank their side effects in order of distress by using two sets of cards naming physical and non-physical effects, respectively. Influencing factors, including treatment and patient characteristics, were also analysed. Patients ranked the non-physical side effect 'Affects my family or partner' first. 'Constantly tired' and 'Loss of hair' were ranked second and third, respectively. Significant differences from previous studies on this topic emerged. In particular, 'Vomiting', a predominant concern in previous studies, almost disappeared, whereas 'Nausea' and 'Loss of hair' remained important side effects in the patients' perception. Interestingly, marital status was predominant in driving patients' perception, being associated with several side effects ('Constantly tired', 'Loss of appetite', 'Affects my work/Home duties', 'Affects my social activities', 'Infertility'). Other significant factors influencing patient's perception of side effects included age, disease characteristics and ongoing anticancer therapy. This study provided information on current status of patients' perceptions of side effects of anticancer treatment. These results could be used in pre-treatment patient education and counselling.

To investigate the effectiveness of presenting medicine side effect risk information in different forms, including that proposed by UK guidelines [[1] Medicines and Healthcare products Regulatory Agency. Always read the leaflet-Getting the best information with every medicine. (Report of the Committee on Safety of Medicines Working Group on Patient Information). London: The Stationery Office, 2005.]. 134 Cancer Research UK (CRUK) website users were recruited via a 'pop-up'. Using a 2x2 factorial design, participants were randomly allocated to one of four conditions and asked to: imagine they had to take tamoxifen, estimate the risks of 4 side effects, and indicate a presentation mode preference. Those presented with absolute frequencies demonstrated greater accuracy in estimating 2 of 4 side effects, and of any side effect occurring, than those presented with frequency bands. Those presented with combined descriptors were more accurate at estimating the risk of pulmonary embolism than those presented with numeric descriptors only. Absolute frequencies outperform frequency bands when presenting side effect risk information. However, presenting such exact frequencies for every side effect may be much less digestible than all side effects listed under 5 frequency bands. Combined numerical and verbal descriptors may be better than numeric only descriptors when describing infrequent side effects. Information about side effects should be presented in ways that patients prefer, and which result in most accurate risk estimates. Copyright (c) 2009 Elsevier Ireland Ltd. All rights reserved.
Medication Side Effects among People with Epilepsy Taking Phenobarbital in Zambia
Elafros, Melissa A.; Bui, Esther; Birbeck, Gretchen L.
2014-01-01
Phenobarbital remains one of the most widely used antiepileptic drugs worldwide, yet there are limited data regarding side effects associated with its use in routine clinical care settings in low-income countries. Available data suggests that phenobarbital is as effective as other first-line drugs for treating tonic-clonic seizures, but side effect reports differ widely between high and low-income settings. A better understanding of phenobarbital side effect profile and severity in low-income settings is warranted given its role in efforts to decrease the epilepsy treatment gap. We used the Liverpool Adverse Events Profile (LEAP) to assess side effects in consecutive patients with epilepsy on phenobarbital seeking care in rural Zambia. Data regarding age, gender, medication dose, and medication adherence were also collected. T-tests and Spearman’s correlation coefficient were used to assess predictors of LEAP score and medication adherence. Thirty-five patients receiving a mean dose of 2.1 mg/kg/day (SD: 2.78 mg/kg/day) of phenobarbital were assessed. All participants reported at least one side effect in the previous four weeks with a median of 6 symptoms (IQR: 4–8) and a mean side effects score of 28/76 (SD: 5.38). Over half reported sleepiness and dizziness. Memory problems and depression were also common (both 46%). Total LAEP score was not associated with age (p=0.88), gender (p=0.17), or phenobarbital dose (p=0.13). Medication adherence was not associated with side effects total score (p=0.56). Rural Zambian adults taking phenobarbital at doses recommended by the WHO report a significant number of side effects. The most common side effects reported were similar to those reported in high-income countries. The significant burden of phenobarbital-associated side effects in this African cohort is in contrast to data from non-randomized clinical trials in China that reported phenobarbital to be well-tolerated with few side effects. Additional investigations regarding phenobarbital side effects in routine care in low income settings is warranted. PMID:25219354

Side effect similarities of drugs have recently been employed to predict new drug targets, and networks of side effects and targets have been used to better understand the mechanism of action of drugs. Here, we report a large-scale analysis to systematically predict and characterize proteins that cause drug side effects. We integrated phenotypic data obtained during clinical trials with known drug–target relations to identify overrepresented protein–side effect combinations. Using independent data, we confirm that most of these overrepresentations point to proteins which, when perturbed, cause side effects. Of 1428 side effects studied, 732 were predicted to be predominantly caused by individual proteins, at least 137 of them backed by existing pharmacological or phenotypic data. We prove this concept in vivo by confirming our prediction that activation of the serotonin 7 receptor (HTR7) is responsible for hyperesthesia in mice, which, in turn, can be prevented by a drug that selectively inhibits HTR7. Taken together, we show that a large fraction of complex drug side effects are mediated by individual proteins and create a reference for such relations. PMID:23632385

Drug side effects are one of the public health concerns. Using powerful machine-learning methods to predict potential side effects before the drugs reach the clinical stages is of great importance to reduce time consumption and protect the security of patients. Recently, researchers have proved that the central nervous system (CNS) side effects of a drug are closely related to its permeability to the blood-brain barrier (BBB). Inspired by this, we proposed an extended neighborhood-based recommendation method to predict CNS side effects using drug permeability to the BBB and other known features of drug. To the best of our knowledge, this is the first attempt to predict CNS side effects considering drug permeability to the BBB. Computational experiments demonstrated that drug permeability to the BBB is an important factor in CNS side effects prediction. Moreover, we built an ensemble recommendation model and obtained higher AUC score (area under the receiver operating characteristic curve) and AUPR score (area under the precision-recall curve) on the data set of CNS side effects by integrating various features of drug.
An Ensemble Approach for Drug Side Effect Prediction
Jahid, Md Jamiul; Ruan, Jianhua

In silico prediction of drug side-effects in early stage of drug development is becoming more popular now days, which not only reduces the time for drug design but also reduces the drug development costs. In this article we propose an ensemble approach to predict drug side-effects of drug molecules based on their chemical structure. Our idea originates from the observation that similar drugs have similar side-effects. Based on this observation we design an ensemble approach that combine the results from different classification models where each model is generated by a different set of similar drugs. We applied our approach to 1385 side-effects in the SIDER database for 888 drugs. Results show that our approach outperformed previously published approaches and standard classifiers. Furthermore, we applied our method to a number of uncharacterized drug molecules in DrugBank database and predict their side-effect profiles for future usage. Results from various sources confirm that our method is able to predict the side-effects for uncharacterized drugs and more importantly able to predict rare side-effects which are often ignored by other approaches. The method described in this article can be useful to predict side-effects in drug design in an early stage to reduce experimental cost and time. PMID:25327524

Continuous positive airway pressure (CPAP) is the treatment of choice for obstructive sleep apnoea syndrome (OSAS), but side-effects are common. No validated self-rating scale measuring side-effects to CPAP treatment exists today. The aim was to develop the side-effects to CPAP treatment inventory (SECI), and investigate the validity and reliability of the instrument among patients with OSAS. SECI was developed on the basis of: (1) in-depth interviews with 23 patients; (2) examination of the scientific literature and (3) consensus agreement of a multi-professional expert panel. This yielded 15 different types of side-effects related to CPAP treatment. Each side-effect has three sub-questions (scales): perceived frequency (a) and magnitude (b) of the side-effect, as well as its perceived impact on CPAP use (c). A cross-sectional descriptive design was used. A total of 329 patients with OSAS with an average use of CPAP treatment for 39 months (2 weeks to 182 months) were recruited. Data were collected with SECI, and obtained from medical records (clinical variables and data related to CPAP treatment). Construct validity was confirmed with factor analysis (principal component analysis with orthogonal rotation). A logical two-factor solution, the device subscale and symptom subscale, emerged across all three scales. The symptom subscale describing physical and psychological side-effects and the device subscale described mask and device-related side-effects. Internal consistency reliability of the three scales was good (Cronbach's α = 0.74-0.86) and acceptable for the subscales (Cronbach's α = 0.62-0.86). The satisfactory measurement properties of this new instrument are promising and indicate that SECI can be used to measure side-effects to CPAP treatment. © 2010 European Sleep Research Society.
Reconstructive Management of Devastating Electrical Injuries to the Face.

Devastating fourth-degree electrical injuries to the face and head pose significant reconstructive challenges. To date, there have been few peer-reviewed articles in the literature that describe those reconstructive challenges. The authors present the largest case series to date that describes the management of these injuries, including the incorporation of face transplantation. A retrospective case series was conducted of patients with devastating electrical injuries to the face who were managed at two level-1 trauma centers between 2007 and 2011. Data describing patient injuries, initial management, and reconstructive procedures were collected. Five patients with devastating electrical injuries to the face were reviewed. After initial stabilization and treatment of life-threatening injuries, all five underwent burn excision and microsurgical reconstruction using distant flaps. Two of the patients eventually underwent face transplantation. The authors describe differences in management between the two trauma centers, one of which had the availability for composite tissue allotransplantation; the other did not. Also described is how initial attempts at traditional reconstruction affected the eventual face transplantation. The care of patients with complex electrical burns must be conducted in a multidisciplinary fashion. As with all other trauma, the initial priority should be management of the airway, breathing, and circulation. Additional considerations include cardiac arrhythmias and renal impairment attributable to myoglobinuria. Before embarking on aggressive reconstruction attempts, it is advisable to determine early whether the patient is a candidate for face transplantation in order to avoid antigen sensitization, loss of a reconstructive "lifeboat," surgical plane disruption, and sacrifice of potential recipient vessels.

Motivation: Identifying the emergence and underlying mechanisms of drug side effects is a challenging task in the drug development process. This underscores the importance of system–wide approaches for linking different scales of drug actions; namely drug-protein interactions (molecular scale) and side effects (phenotypic scale) toward side effect prediction for uncharacterized drugs. Results: We performed a large-scale analysis to extract correlated sets of targeted proteins and side effects, based on the co-occurrence of drugs in protein-binding profiles and side effect profiles, using sparse canonical correlation analysis. The analysis of 658 drugs with the two profiles for 1368 proteins and 1339 side effects led to the extraction of 80 correlated sets. Enrichment analyses using KEGG and Gene Ontology showed that most of the correlated sets were significantly enriched with proteins that are involved in the same biological pathways, even if their molecular functions are different. This allowed for a biologically relevant interpretation regarding the relationship between drug–targeted proteins and side effects. The extracted side effects can be regarded as possible phenotypic outcomes by drugs targeting the proteins that appear in the same correlated set. The proposed method is expected to be useful for predicting potential side effects of new drug candidate compounds based on their protein-binding profiles.

Variations in judgments of intentional action and moral evaluation across eight cultures.
Robbins, Erin; Shepard, Jason; Rochat, Philippe
2017-07-01
Individuals tend to judge bad side effects as more intentional than good side effects (the Knobe or side-effect effect). Here, we assessed how widespread these findings are by testing eleven adult cohorts of eight highly contrasted cultures on their attributions of intentional action as well as ratings of blame and praise. We found limited generalizability of the original side-effect effect, and even a reversal of the effect in two rural, traditional cultures (Samoa and Vanuatu) where participants were more likely to judge the good side effect as intentional. Three follow-up experiments indicate that this reversal of the side-effect effect is not due to semantics and may be linked to the perception of the status of the protagonist. These results highlight the importance of factoring cultural context in our understanding of moral cognition. Copyright © 2017. Published by Elsevier B.V.
Side-effects of topical steroids: A long overdue revisit.
Coondoo, Arijit; Phiske, Meghana; Verma, Shyam; Lahiri, Koushik
2014-10-01
The introduction of topical steroids (TS) of varying potency have rendered the therapy of inflammatory cutaneous disorders more effective and less time-consuming. However the usefulness of these has become a double edged sword with constantly rising instances of abuse and misuse leading to serious local, systemic and psychological side effects. These side effects occur more with TS of higher potency and on particular areas of the body like face and genitalia. The article reviews the side effects of TS with special mention about peadiatric age group, also includes the measures for preventing the side effects.

Effectiveness and side-effect profile data on pharmacotherapy for daytime sleepiness in central hypersomnias are based largely upon randomized controlled trials. Evidence regarding the use of combination therapy is scant. The aim of this study was to examine the effectiveness and occurrence of drug-related side effects of these drugs in routine clinical practice. Adult patients diagnosed with a central hypersomnia during a 54-month period at a tertiary sleep disorders centre were identified retrospectively. Side effects were recorded at every follow-up visit. A total of 126 patients, with 3275 patient-months of drug exposure, were categorized into narcolepsy type 1 (n = 70), narcolepsy type 2 (n = 47) and idiopathic hypersomnia (n = 9). Modafinil was the most common drug used as a first-line treatment (93%) and in combination therapy (70%). Thirty-nine per cent of the patients demonstrated a complete, 25% partial and 36% a poor response to treatment. Combination treatment improved daytime sleepiness in 55% of the patients with residual symptoms despite monotherapy. Sixty per cent of patients reported side effects, and 30% reported treatment-limiting side effects. Drugs had similar side-effect incidence (P = 0.363) and their side-effect profile met those reported in the literature. Twenty-seven per cent of the patients received combination treatment and had fewer side effects compared to monotherapy (29.4% versus 60%, respectively, P = 0.001). Monotherapy appears to achieve satisfactory symptom control in most patients with central hypersomnia, but significant side effects are common. Combination therapy appears to be a useful and safe option in patients with refractory symptoms. © 2017 European Sleep Research Society.
Alzheimer’s Disease and Age-Related Memory Decline (Preclinical)
Terry, Alvin V.; Callahan, Patrick M.; Hall, Brandon; Webster, Scott J.
2011-01-01
An unfortunate result of the rapid rise in geriatric populations worldwide is the increasing prevalence of age-related cognitive disorders such as Alzheimer’s disease (AD). AD is a devastating neurodegenerative illness that is characterized by a profound impairment of cognitive function, marked physical disability, and an enormous economic burden on the afflicted individual, caregivers, and society in general. The rise in elderly populations is also resulting in an increase in individuals with related (potentially treatable) conditions such as “Mild Cognitive Impairment” (MCI) which is characterized by a less severe (but abnormal) level of cognitive impairment and a high-risk for developing dementia. Even in the absence of a diagnosable disorder of cognition (e.g., AD, MCI), the perception of increased forgetfulness and declining mental function is a clear source of apprehension in the elderly. This is a valid concern given that even a modest impairment of cognitive function is likely to be associated with significant disability in a rapidly evolving, technology-based society. Unfortunately, the currently available therapies designed to improve cognition (i.e., for AD and other forms of dementia) are limited by modest efficacy, adverse side effects, and their effects on cognitive function are not sustained over time. Accordingly, it is incumbent on the scientific community to develop safer and more effective therapies that improve and/or sustain cognitive function in the elderly allowing them to remain mentally active and productive for as long as possible. As diagnostic criteria for memory disorders evolve, the demand for pro-cognitive therapeutic agents is likely to surpass AD and dementia to include MCI and potentially even less severe forms of memory decline. The purpose of this review is to provide an overview of the contemporary therapeutic targets and preclinical pharmacologic approaches (with representative drug examples) designed to enhance memory function.

Pancreatic ductal adenocarcinoma (PDAC) is one of the most devastating malignancies in patients, and there is an urgent need for an effective treatment method. Herein, we report a novel gold nanocluster-based platform for confocal laser endomicroscopy-guided photothermal therapy (PTT)/photodynamic therapy (PDT) for PDAC, which consists of four components: the PTT-carrier gold nanocluster, an active targeting ligand U11 peptide, a Cathepsin E (CTSE)-sensitive PDT therapy prodrug, and a CTSE-sensitive imaging agent (cyanine dye Cy5.5). Due to the strong coupling among cross-linked gold nanoparticles (AuNPs), the surface plasmon resonance peak of nanoclusters shifts to the near-infrared (NIR) region, thus making the nanoclusters useful in the effective PTT therapy. In the system, the labeling of nanoclusters with U11 peptide can distinctly increase their affinity and accelerate their uptake by pancreatic cancer cells. Cell apoptosis staining demonstrates that, upon incorporation of the uPAR-targeted unit, the antitumor efficacy of CTSE-sensitive nanocluster AuS-U11 is significantly enhanced with respect to that of the non-targeted nanocluster AuS-PEG and the insensitive nanocluster AuC-PEG. In vivo and ex vivo optical imaging confirms the high accumulation of AuS-U11 in the in situ pancreatic tumor model. Therapeutic studies further show that the combination of active targeting for tumor tissue, enzyme-triggered drug release of 5-ALA and fluorescent dye Cy5.5 in nanoclusters AuS-U11 could achieve optimal therapeutic efficacy with endomicroscopy-guided photothermal/photodynamic therapy with minimal side effects. As a consequence, the delicate gold nanocluster concept provides a promising strategy to enhance the therapy efficiency in the most challenging PDAC treatment. Copyright © 2017 Elsevier Ltd.

Head and neck cancer patients treated by radiation commonly suffer from a devastating side effect known as dry-mouth syndrome, which results from the irreversible loss of salivary gland function via mechanisms that are not completely understood. In this study, we used a mouse model of radiation-induced salivary hypofunction to investigate the outcomes of DNA damage in the head and neck region. We demonstrate that the loss of salivary function was closely accompanied by cellular senescence, as evidenced by a persistent DNA damage response (γH2AX and 53BP1) and the expression of senescence-associated markers (SA-βgal, p19ARF, and DcR2) and secretory phenotype (SASP) factors (PAI-1 and IL6). Notably, profound apoptosis or necrosis was not observed in irradiated regions. Signs of cellular senescence were also apparent in irradiated salivary glands surgically resected from human patients who underwent radiotherapy. Importantly, using IL6 knockout mice, we found that sustained expression of IL6 in the salivary gland long after initiation of radiation-induced DNA damage was required for both senescence and hypofunction. Additionally, we demonstrate that IL6 pretreatment prevented both senescence and salivary gland hypofunction via a mechanism involving enhanced DNA damage repair. Collectively, these results indicate that cellular senescence is a fundamental mechanism driving radiation-induced damage in the salivary gland and suggest that IL6 pretreatment may represent a promising therapeutic strategy to preserve salivary gland function in head and neck cancer patients undergoing radiotherapy. ©2016 American Association for Cancer Research.
Expitope: a web server for epitope expression.

Adoptive T cell therapies based on introduction of new T cell receptors (TCRs) into patient recipient T cells is a promising new treatment for various kinds of cancers. A major challenge, however, is the choice of target antigens. If an engineered TCR can cross-react with self-antigens in healthy tissue, the side-effects can be devastating. We present the first web server for assessing epitope sharing when designing new potential lead targets. We enable the users to find all known proteins containing their peptide of interest. The web server returns not only exact matches, but also approximate ones, allowing a number of mismatches of the users choice. For the identified candidate proteins the expression values in various healthy tissues, representing all vital human organs, are extracted from RNA Sequencing (RNA-Seq) data as well as from some cancer tissues as control. All results are returned to the user sorted by a score, which is calculated using well-established methods and tools for immunological predictions. It depends on the probability that the epitope is created by proteasomal cleavage and its affinities to the transporter associated with antigen processing and the major histocompatibility complex class I alleles. With this framework, we hope to provide a helpful tool to exclude potential cross-reactivity in the early stage of TCR selection for use in design of adoptive T cell immunotherapy.

Mobile phones as a new memory aid: a preliminary investigation using case studies.
Wade, T K; Troy, J C
2001-04-01
Memory impairment is one of the most common concerns following a brain injury of any severity. The use of effective external memory aids can help minimize the devastating effects such memory impairment can have on an individual's everyday life. Reviewed in this report are case studies of five individuals suffering significant everyday memory problems that were given a new memory aid that utilizes standard mobile phones. Measurements included diary-format observations and qualitative feedback. The results of the study show promising outcomes for all of the cases, and have led to recent adaptations to allow for wider and more effective use of this memory aid.
Extravasation of chemotherapy.
Langer, Seppo W
2010-07-01
Extravasation of chemotherapy is a feared complication of anticancer therapy. The accidental leakage of cytostatic agents into the perivascular tissues may have devastating short-term and long-term consequences for patients. In recent years, the increased focus on chemotherapy extravasation has led to the development of international guidelines that have proven useful tools in daily clinical practice. Moreover, the tissue destruction in one of the most dreaded types of extravasation (ie, anthracycline extravasation) now can effectively be prevented with a specific antidote, dexrazoxane.
Nutritionally enhanced rice to combat malnutrition disorders of the poor.

2003-06-01
Major deficiency disorders, including vitamin A deficiency, are especially common in countries in which rice is the staple food. In response to the devastating effects of vitamin A deficiency, which may include blindness and, even death, "Golden Rice" has been developed to deliver this nutrient to those populations who need it most. The case of Golden Rice is used to demonstrate the challenges of radical GMO opposition, consumer acceptance, and regulation of biotechnology-derived foods.

Management of recurrent cervical cancer by reirradiation after radiation treatment remains controversial. In Indonesia, there is currently no data about reirradiation tumor response and side effects. This study aims to assess the tumor response to and side effects of reirradiation, the effect of time interval between first radiation treatment and cancer recurrence on the tumor response and side effects, and the effect of tumor size on tumor response. A cohort retrospective study with no comparison was done with the Radiotherapy Department at Cipto Mangunkusumo General Hospital, Jakarta. Participants were recurrent cervical cancer patients undergoing reirradiation. Data was collected from patients’ medical records and follow-up phone calls. Twenty-two patients participated in this study. Nine patients (40.9%) had complete responses, 10 patients (45.5%) had partial responses, 1 patient (4.5%) had a stable response, and 2 patients (9.1%) had tumor progressions. In general, 15 patients (68.2%) had no to light side effects (grade 0-2 RTOG) and 7 patients (31.8%) had severe side effects (grade 3-4 RTOG). Four patients (18.1%) had severe gastrointestinal acute side effects, 6 patients (27.3%) had severe gastrointestinal late side effects, 2 patients (9.1%) had severe urogenital side effects, and there were no patients had severe urogenital late side effects. There was no significant difference in tumor response between patients with time interval between first radiation treatment and recurrence of <12 months vs. ≥12 months. There was no significant difference in tumor response between patients with tumor size ≤4 cm vs. >4 cm. Reirradiation can be considered as a modality in recurrent cervical cancer management since good tumor response was achieved and the majority of patients had no to light side effects (grade 0-2 RTOG). This study found no correlation between tumor response, side effects, and time gap between first radiation treatment and recurrence of <12 months vs. ≥12 months. There was also no correlation between tumor response and tumor size of ≤4 cm vs. > 4 cm.
Gravitational sliding of the Mt. Etna massif along a sloping basement

Geological field evidence and laboratory modelling indicate that volcanoes constructed on slopes slide downhill. If this happens on an active volcano, then the movement will distort deformation data and thus potentially compromise interpretation. Our recent GPS measurements demonstrate that the entire edifice of Mt. Etna is sliding to the ESE, the overall direction of slope of its complex, rough sedimentary basement. We report methods of discriminating the sliding vector from other deformation processes and of measuring its velocity, which averaged 14 mm year-1 during four intervals between 2001 and 2012. Though sliding of one sector of a volcano due to flank instability is widespread and well-known, this is the first time basement sliding of an entire active volcano has been directly observed. This is important because the geological record shows that such sliding volcanoes are prone to devastating sector collapse on the downslope side, and whole volcano migration should be taken into account when assessing future collapse hazard. It is also important in eruption forecasting, as the sliding vector needs to be allowed for when interpreting deformation events that take place above the sliding basement within the superstructure of the active volcano, as might occur with dyke intrusion or inflation/deflation episodes.
The Janus face of Darwinian competition
Hintze, Arend; Phillips, Nathaniel; Hertwig, Ralph
2015-01-01
Without competition, organisms would not evolve any meaningful physical or cognitive abilities. Competition can thus be understood as the driving force behind Darwinian evolution. But does this imply that more competitive environments necessarily evolve organisms with more sophisticated cognitive abilities than do less competitive environments? Or is there a tipping point at which competition does more harm than good? We examine the evolution of decision strategies among virtual agents performing a repetitive sampling task in three distinct environments. The environments differ in the degree to which the actions of a competitor can affect the fitness of the sampling agent, and in the variance of the sample. Under weak competition, agents evolve decision strategies that sample often and make accurate decisions, which not only improve their own fitness, but are good for the entire population. Under extreme competition, however, the dark side of the Janus face of Darwinian competition emerges: Agents are forced to sacrifice accuracy for speed and are prevented from sampling as often as higher variance in the environment would require. Modest competition is therefore a good driver for the evolution of cognitive abilities and of the population as a whole, whereas too much competition is devastating. PMID:26354182

The objective of this study was to estimate the prevalence of possible oral corticosteroid (OCS)-related side effects and health care resource use and costs in patients with asthma. This was a cross-sectional, matched-cohort, retrospective study using a commercial claims database. Adults with asthma diagnosis codes and evidence of asthma medication use were studied. Patients with high OCS use (≥30 days of OCS annually) were divided into those who did versus those who did not experience OCS-related possible side effects. Their health care resource use and costs were compared using linear regression or negative binomial regression models, adjusting for age, sex, geographic region, Charlson Comorbidity Index score, and chronic obstructive pulmonary disease status. After adjustment, high OCS users with possible side effects were more likely to have office visits (23.0 vs 19.6; P <0.001) and hospitalizations (0.44 vs 0.22; P <0.001) than those without possible side effects. Emergency department visits were similar between the groups. High OCS users with possible side effects had higher adjusted total annual mean health care costs ($25,168) than those without such side effects ($21,882; P =0.009). Among high OCS users, patients with possible OCS-related side effects are more likely to use health care services than those without such side effects. Although OCS may help control asthma and manage exacerbations, OCS side effects may result in additional health care resource use and costs, highlighting the need for OCS-sparing asthma therapies.

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.

There is no cure for Duchenne Muscular Dystrophy (DMD); treatment is symptomatic and corticosteroids slow the progression. Side effects of corticosteroids - especially the physical effects - have been described, however patients' and caregivers perception on chronic corticosteroid treatment and their side effects is less well known, in particular with regards to cognition, behaviour, and emotional functioning. The primary aim of this pilot study was to (i) construct a self-report questionnaire to assess the perceived benefits and side effects of corticosteroids for patients with DMD and their parents. Furthermore we aimed to (ii) investigate the psychometric qualities of this questionnaire, (iii) whether there was a difference between parents' and patient's perceptions, and finally (iv) to what extent reported side effects may alter over time. A 23-item questionnaire (SIDECORT: side effect of corticosteroids) was constructed to assess the perception of these benefits and side effects in a systematic manner. In total, 86 patients (aged 5 - 28 years) and 125 of their parents completed the questionnaire. Internal consistency was good. Using factor analyses on the side effect items as reported by parents, two underlying factors were found, with the first factor describing cognitive, behavioural and emotional functioning, and the second factor describing physical functioning. The potential benefits of corticosteroids were highly rated among both parents and patients, although parents rated the importance of the benefits higher than their sons (p = 0.002). Similarly, parents rated the severity of the side effects generally higher than their sons (p = 0.011), especially with regards to the physical side effects (p = 0.014). Based on the parent's perception, the neurodevelopmental side effects generally appeared to decline the longer corticosteroids were used. To our knowledge, this is the first explicit study on perceived cognitive-, behavioural-, and emotional side effects and the allocation of benefits to corticosteroids in DMD. On the basis of our research we suggest a short form questionnaire, which proves to be reliable and valid for research- and clinical practice. This questionnaire could provide useful insights for the care of boys and men with DMD.

Zolpidem is one of the newer medications developed for the treatment of insomnia. It is an imidazopyridine agent that is an alternative to the typical sedative-hypnotic agents. Zolpidem use is gaining favor because of its efficacy and its side effect profile, which is milder and less problematic than that of the benzodiazepines and barbiturates used to treat insomnia. Still, side effects are not uncommon with zolpidem use. We report a series of cases in which the patients developed delirium, nightmares and hallucinations during treatment with zolpidem. We will review its pharmacology, discuss previous reports of central nervous system side effects, examine the impact of drug interactions with concurrent use of antidepressants, examine gender differences in susceptibility to side effects, and explore the significance of protein binding in producing side effects.

Storm-triggered landslides cause loss of life, property damage, and landscape alterations. For instance, the remnants of Hurricane Camille in 1969 caused 109 deaths in central Virginia, after 600 millimeters of rain fell in mountainous terrain in 6 hours. More recently, on 8 August 2010, a rainstorm-induced landslide devastated the Chinese county of Zhouqu, causing more than 1000 deaths. A new modeling study by Ren examines the multiple factors, natural and human caused, that came together to produce this event. Three things contribute to storm-triggered landslides: geological condition, surface loading and vegetation roots, and extreme precipitation.
Don't forget about the Christchurch earthquake: Lessons learned from this disaster
Hamburger, Michael W.; Mooney, Walter D.
2011-01-01
In the aftermath of the devastating magnitude-9.0 earthquake and tsunami that struck the Tohoku region of Japan on March 11, attention quickly turned away from a much smaller, but also highly destructive earthquake that struck the city of Christchurch, New Zealand, just a few weeks earlier, on Feb. 22. Both events are stark reminders of human vulnerability to natural disasters and provide a harsh reality check: Even technologically advanced countries with modern building codes are not immune from earthquake disasters. The Christchurch earthquake carried an additional message: Urban devastation can be triggered even by moderate-sized earthquakes.

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.

Psychological response to the Oklahoma City bombing.
Krug, R S; Nixon, S J; Vincent, R
1996-01-01
The bombing of the Alfred P. Murrah Federal Office Building in Oklahoma City was the most devastating terrorist activity that has occurred in America. Prevention of revictimization of persons seriously affected by the bombing was central to the planned response to this tragedy. Coordination and collaboration among local, state, and national agencies promoted effective clinical services provision, research facilitation, and prevention of revictimization. Information gathered from this cooperative effort will contribute to the effort to minimize the potential for such tragedies in the future as well as help to develop prevention and intervention strategies to reduce the effects when the next such disaster occurs.

In less than 2 years since entry into the Americas, we have witnessed the emergent spread of Zika virus into large subsets of immunologically naïve human populations and then encountered the devastating effects of microcephaly and brain anomalies that can arise from in utero infection with the virus. Diagnostic evaluation and management of affected infants continues to evolve as our understanding of Zika virus rapidly advances. The development of a safe and effective vaccine holds the potential to attenuate the spread of infection and limit the impact of congenital infection. Copyright © 2017 Elsevier Inc.

A magnitude 6.5 earthquake devastated the town of Bam in southeast Iran on 26 December 2003. Surface displacements and decorrelation effects, mapped using Envisat radar data, reveal that over 2 m of slip occurred at depth on a fault that had not previously been identified. It is common for earthquakes to occur on blind faults which, despite their name, usually produce long-term surface effects by which their existence may be recognised. However, in this case there is a complete absence of morphological features associated with the seismogenic fault that destroyed Bam.

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.
Optimizing quality of life in patients with idiopathic pulmonary fibrosis
van Manen, Mirjam J. G.; Geelhoed, J. J. Miranda.; Tak, Nelleke C.; Wijsenbeek, Marlies S.
2017-01-01
Idiopathic pulmonary fibrosis (IPF) is a devastating, progressive and ultimately fatal lung disease. The combination of poor prognosis, uncertainty of disease course and severe symptom burden heavily impacts patients’ and their families’ quality of life. Though new antifibrotic drugs have been shown to decrease disease progression, the effect on health-related quality of life (HRQOL) has not been convincingly demonstrated. In a relentless disease such as IPF, striving to optimize HRQOL should complement the endeavour to prolong life. Unfortunately, there is a paucity of interventions improving symptoms and functionality for patients with IPF, and research focusing on symptom improvement, and assessing and optimizing HRQOL, is limited. This review summarizes the most recent insights into measuring and improving quality of life for patients with IPF, and discusses challenges in the management of this devastating disease. Moreover, we postulate a new model for continuous care in IPF – ‘the ABCDE of IPF care’: Assessing patients’ needs; Backing patients by giving information and support; delivering Comfort care by focusing on treating symptoms and taking into account Comorbidities; striving to prolong life by Disease modification; helping and preparing patients and their caregivers for the eventual End-of-life events that are likely to occur.

Proteostasis and Diseases of the Motor Unit.
Rinaldi, Carlo; Mäger, Imre; Wood, Matthew J
2016-01-01
The accumulation in neurons of aberrant protein species, the pathological hallmark of many neurodegenerative diseases, results from a global impairment of key cellular processes governing protein synthesis/degradation and repair mechanisms, also known as the proteostasis network (PN). The growing number of connections between dysfunction of this intricate network of pathways and diseases of the motor unit, where both motor neurons and muscle are primarily affected, has provided momentum to investigate the muscle- and motor neuron-specific response to physiological and pathological stressors and to explore the therapeutic opportunities that manipulation of this process may offer. Furthermore, these diseases offer an unparalleled opportunity to deepen our understanding of the molecular mechanisms behind the intertissue communication and transfer of signals of proteostasis. The most compelling aspect of these investigations is their immediate potential for therapeutic impact: targeting muscle to stem degeneration of the motor unit would represent a dramatic paradigm therapeutic shift for treating these devastating diseases. Here we will review the current state of the art of the research on the alterations of the PN in diseases of the motor unit and its potential to result in effective treatments for these devastating neuromuscular disorders.
Devastating epidemics in recent ages Greek populations.
Kotsiou, Antonia; Michalaki, Vasiliki; Anagnostopoulou, Helen N
2017-12-01
In the recent Greek ages the most devastating epidemics were plague, smallpox, leprosy and cholera. In 1816 plague struck the Ionian and Aegean Islands, mainland Greece, Constantinople and Smyrna. The Venetians ruling the Ionian Islands effectively combated plague in contrast to the Ottomans ruling all other regions. In 1922, plague appeared in Patras refugees who were expelled by the Turks from Smyrna and Asia Minor. Inoculation against smallpox was first performed in Thessaly by the Greek women, and the Greek doctors Emmanouel Timonis (1713, Oxford) and Jakovos Pylarinos (1715, Venice) made relevant scientific publications. The first leper colony opened in Chios Island. In Crete, Spinalonga was transformed into a leper island, which following the Independence War against Turkish occupation and the unification of Crete with Greece in 1913, was classified as an International Leper Hospital. Cholera struck Greece in 1853-1854 brought by the French troops during the Crimean War, and again during the Balkan Wars (1912-13) when the Bulgarian troops brought cholera to northern Greece. Due to successive wars, medical assistance was not always available, so desperate people turned many times to religion through processions in honor of local saints, for their salvation in epidemics.

The Influence of Social Modeling, Gender, and Empathy on Treatment Side Effects.
Faasse, Kate; Parkes, Bryony; Kearney, James; Petrie, Keith J
2018-05-31
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.
"Side effects" of ECT are mainly depressive phenomena and are independent of age.
Brodaty, H; Berle, D; Hickie, I; Mason, C

The aetiology of reported side effects of electroconvulsive therapy (ECT) is unclear. We examined the interaction of depression and age on adverse neuropsychological and putative side effects of ECT. Inpatients (N=81; median age 70 years) with major depression were assessed prospectively pre-ECT, immediately post-ECT and 1-3 years later. Patients were administered the Hamilton Rating Scale for Depression (HRSD), the Global Assessment of Functioning scale (GAF) and neuropsychological tests from the Wechsler Memory Scale. Side effects and total burden scores were rated pre- and post-treatment. HRSD and GAF scores improved with treatment after ECT, but the prevalence and total burden of side effects were unchanged. Side effect burden was related to depression level before and after ECT. Improvement in depression correlated with reduction in side effect burden. There was a significant decline in side effect burden after controlling for change in depression. Patients' scores on neuropsychological measures did not appear to change after ECT or between pre-ECT and follow-up. Re-analysis, allowing for age, chronicity of depression, medication use and development of dementia, did not alter the findings. lack of a control group, lack of information on ECT technique, incomplete data sets and limited neuropsychological testing. ECT, an effective treatment for depression, does not cause significant side effects or neuropsychological impairment, which are more likely to be depressive phenomena. ECT appears to be safe for old (> or =65 years) and very old (> or =75 years) patients, who do not appear to be more susceptible to adverse effects.
A hierarchical anatomical classification schema for prediction of phenotypic side effects
Kanji, Rakesh
2018-01-01
Prediction of adverse drug reactions is an important problem in drug discovery endeavors which can be addressed with data-driven strategies. SIDER is one of the most reliable and frequently used datasets for identification of key features as well as building machine learning models for side effects prediction. The inherently unbalanced nature of this data presents with a difficult multi-label multi-class problem towards prediction of drug side effects. We highlight the intrinsic issue with SIDER data and methodological flaws in relying on performance measures such as AUC while attempting to predict side effects.We argue for the use of metrics that are robust to class imbalance for evaluation of classifiers. Importantly, we present a ‘hierarchical anatomical classification schema’ which aggregates side effects into organs, sub-systems, and systems. With the help of a weighted performance measure, using 5-fold cross-validation we show that this strategy facilitates biologically meaningful side effects prediction at different levels of anatomical hierarchy. By implementing various machine learning classifiers we show that Random Forest model yields best classification accuracy at each level of coarse-graining. The manually curated, hierarchical schema for side effects can also serve as the basis of future studies towards prediction of adverse reactions and identification of key features linked to specific organ systems. Our study provides a strategy for hierarchical classification of side effects rooted in the anatomy and can pave the way for calibrated expert systems for multi-level prediction of side effects.

physicians are often asked to prognosticate soon after a patient presents with stroke. This study aimed to compare two outcome prediction scores (Five Simple Variables [FSV] score and the PLAN [Preadmission comorbidities, Level of consciousness, Age, and focal Neurologic deficit]) with informal prediction by physicians. demographic and clinical variables were prospectively collected from consecutive patients hospitalised with acute ischaemic or haemorrhagic stroke (2012-13). In-person or telephone follow-up at 6 months established vital and functional status (modified Rankin score [mRS]). Area under the receiver operating curves (AUC) was used to establish prediction score performance. five hundred and seventy-five patients were included; 46% female, median age 76 years, 88% ischaemic stroke. Six months after stroke, 47% of patients had a good outcome (alive and independent, mRS 0-2) and 26% a devastating outcome (dead or severely dependent, mRS 5-6). The FSV and PLAN scores were superior to physician prediction (AUCs of 0.823-0.863 versus 0.773-0.805, P < 0.0001) for good and devastating outcomes. The FSV score was superior to the PLAN score for predicting good outcomes and vice versa for devastating outcomes (P < 0.001). Outcome prediction was more accurate for those with later presentations (>24 hours from onset). the FSV and PLAN scores are validated in this population for outcome prediction after both ischaemic and haemorrhagic stroke. The FSV score is the least complex of all developed scores and can assist outcome prediction by physicians. © The Author 2016.

Cognitive impairment and pragmatics.
Gutiérrez-Rexach, Javier; Schatz, Sara
2016-01-01
One of the most important ingredients of felicitous conversation exchanges is the adequate expression of illocutionary force and the achievement of perlocutionary effects, which can be considered essential to the functioning of pragmatic competence. The breakdown of illocutionary and perlocutionary functions is one of the most prominent external features of cognitive impairment in Alzheimer's Disease, with devastating psychological and social consequences for patients, their family and caregivers. The study of pragmatic functions is essential for a proper understanding of the linguistic and communicative aspects of Alzheimer's disease.
Obstetric nephrology: preeclampsia--the nephrologist's perspective.
Umans, Jason G
2012-12-01
Preeclampsia, a common and potentially devastating multisystem disorder unique to human pregnancy, represents a novel form of secondary hypertension with complex renal and systemic effects. Recent translational and clinical research reveals key pathophysiologic contributions due to dysregulation of angiogenic factors and of angiotensin signaling. Despite these insights, there are still difficulties in the clinical definition of preeclampsia and in the diagnosis of women with this disorder. Although recent research suggests the potential for new preventive and treatment strategies, most have not yet been shown ready for clinical use.
Recognition and treatment of neuropsychiatric disturbances in Parkinson's disease.
Akbar, Umer; Friedman, Joseph H
2015-01-01
The non-motor symptoms of Parkinson's disease (PD) have been attracting increasing attention due to their ubiquitous nature and their often devastating effects on the quality of life. Behavioral problems in PD include dementia, depression, apathy, fatigue, anxiety, psychosis, akathisia, personality change, sleep disorders and impulse control disorders. Some of these are intrinsic to the neuropathology while others occur as an interplay between pathology, psychology and pharmacology. While few data exist for guiding therapy, enough is known to guide therapy in a rational manner.

Christensen, Carl
2008-06-01
Although the percentage of pregnant patients who use illicit drugs is relatively low, the effects can be devastating on both mother and fetus-loss of custody, growth restriction, placental abruption, and death. The practicing obstetrician may be unfamiliar with the various presentations of chemical dependency in pregnancy, including intoxication and withdrawal, and difficulty in making the diagnosis. The obstetrician is in the unique situation of being responsible for the safety of both mother and fetus, which may involve engaging the unwilling patient in treatment.
Inventing urine incontinence devices for women.

Nurses have long been aware of the devastating effects of urinary incontinence on women. Although women may find diapers, pads and protective clothing valuable protection, there are few options for a continuous wear, external urine incontinence device (EUID). Inventors have attempted to develop an EUID since ancient times; the first United States patent for an EUID was awarded in 1949. The purpose of this paper is to review technological considerations for development of an external urinary incontinence device for women. Patents and products illustrate the considerations.

Once a sign of modernization and growth, dams are often seen today as symbols of environmental and social devastation. Over 800,000 dams have been built worldwide to provide drinking water, flood control, hydropower, irrigation, navigation, and water storage. Dams do indeed provide these things,but at the cost of several adverse, unexpected effects: disruption of ecosystems, decline of fish stocks, forced human and animal resettlements, and diseases such as malaria, which are borne by vectors that thrive in quiet waters.

Inexact measurements can have devastating effects in sciences where precision is of paramount importance. In contrast, morphological sciences rely heavily on description, comparison, and estimation to make meaningful inferences about the structure of humans and other animals. A review of the 1918 edition of Gray's Anatomy shows that the tendency to approximate was as marked nearly a century ago as it is today. Occasionally, objects of comparison may themselves become obsolete, necessitating changes in descriptive terminology. Copyright 2009 American Association of Anatomists.
Cutaneous side effects of doxycycline: a pediatric case series.

Brucellosis is highly endemic in Turkey and doxycycline is commonly used for its treatment. The present study aimed at documenting the cutaneous side effects of doxycycline in pediatric brucellosis patients in Turkey. Pediatric patients with brucellosis that were treated between February 2014 and January 2016 were analyzed retrospectively, and those that developed doxycycline-related cutaneous side effects were identified. Demographic data, epidemiological history, physical examination findings, laboratory test results, anti-brucellosis treatment regimen, duration of follow up and outcome were recorded. Among the 189 brucellosis patients, 141 treated with doxycycline plus rifampicin. Seven patients (5%) (two female and five male) developed doxycycline-related cutaneous side effects. Mean duration of treatment before the onset of cutaneous side effects was 9.5 weeks. Doxycycline therapy was continued in five of these patients and was changed in two patients. In the patients that continued to receive doxycycline the cutaneous side effects gradually improved. Cutaneous side effects of doxycycline should always be a consideration, especially in regions in which brucellosis is endemic and doxycycline is commonly used to treat it.

Despite the medical advancements in HIV treatment, realities of side effects are faced by people living with HIV (PLWH) who receive antiretroviral therapy (ART). Mixed findings have been reported on the association between side effects and ART adherence. However, few studies have explored the combined side effects and behavior-related information on medication adherence. The aim of the current study is to examine moderator role of ART-related knowledge between side effects and ART adherence. A cross-sectional survey was conducted among 2987 PLWH from October 2012 to August 2013 in China. Of the total sample, 2095 patients had received ART and provided ART adherence. Side effects, ART-related knowledge, and ART adherence, as well as potential covariates were assessed. The results revealed that there was a negative relationship of side effects and ART adherence existed among low and medium levels of ART-related knowledge, but not among high level of knowledge. Future interventions to promote HIV medication adherence should focus on providing behavior-related information education among PLWH.

Although previous research has, overall, suggested a moderate relationship between response expectancies (REs) and cancer treatment-related side effects, empirical results have been mixed. We aimed to further explore these relationships, hypothesizing that REs would predict subsequent toxicities with the inclusion of more recent studies, across a broader range of side effects, while incorporating the impact of potential moderators including patients' experience with treatment and measurement methods. We further investigated the impact of REs across individual toxicities. A systematic search and analysis were conducted across four databases (PsychInfo, PubMed, CINAHL, and Embase) and reference lists, from 1985 to February 2016. This provided 27 eligible studies with 4474 participants, through which the main analysis, moderator analyses, and individual side-effect analyses were explored. REs were moderately related to side effects overall (r = 0.26), and effect sizes were significantly influenced by sample diagnostic homogeneity, whereas differences between type and timing of measurement showed trends. Of the 16 toxicities examined, 15 demonstrated significant relationships between REs and side-effect experience, with hair loss (r = 0.48) the strongest. No clear difference emerged between objective and subjective side effects; however, significant differences across individual toxicities were revealed. Findings support a relationship between REs and a wide range of subsequent side effects, yet differences between individual RE-toxicity associations emerged. These findings provide direction for the measurement of side effects and REs and support REs as potential targets for intervention during the informed consent process.

Anaesthesiological considerations on tocolytic and uterotonic therapy in obstetrics.
Vercauteren, M; Palit, S; Soetens, F; Jacquemyn, Y; Alahuhta, S
2009-07-01
Significant side effects of tocolytic and uterotonic substances may be of concern to the anaesthesiologist. Recently, new drugs have been introduced having less side effects for both the mother and the neonate. A literature search was undertaken mainly focusing on meta-analyses, to review the possible side effects that might affect the course of anaesthesia and to suggest which precautions should be considered to prevent the occurrence of significant interactions with anaesthetic manipulations and drugs. Magnesium sulphate has a proven benefit in lowering systolic blood pressure and preventing the occurrence of eclampsia, but not as a tocolytic. beta-adrenergic agonists are being abandoned due to the availability of tocolytic agents causing less side effects. Calcium channel blockers (CCB) are frequently used but can cause major maternal cardiovascular complications. Nitroglycerin seems to be appreciated as an acute tocolytic rather than a routine substance during pre-term labour. Cyclo-oxygenase-2 inhibitors are still under investigation but their tocolytic benefit is questionable mainly due to foetal side effects. Atosiban is considered the first-choice tocolytic. With respect to oxytocic drugs, oxytocine, prostaglandines and methylergometrine may all cause serious side effects especially when combined. The cardiovascular side effects of prostaglandins and methylergometrine can be life-threatening. Both oxytocin and carbetocin have a rather low risk for maternal complications. Atosiban and CCB are at least as effective tocolytic agents as beta-mimetics but have significantly less side effects. Magnesium sulphate can cause neuromuscular blockade, especially when combined with CCB. Concerning oxytocic agents, short-acting oxyctocin and long-acting carbetocin have the least side effects as compared with prostaglandins and methylergometrine.

Many therapists practise PC6 acupuncture for emesis (nausea and vomiting) during pregnancy, different cancer therapies, palliative care, after surgery, or to induce relaxing effects in general. Knowledge of side effects is central to shared decision-making. To describe the type and frequency of side effects and the level of needle-induced pain during PC6 acupuncture. We included 1298 PC6 acupuncture treatments, delivered to 221 participants (77% women, mean age 52.5, range 18-91 years). The subjects had received genuine PC6 acupuncture, in one of two previous randomised controlled trials, aimed at inducing antiemetic (n=100, with 100 providing data on side effects and 94 on needle-induced pain, respectively) or relaxing (n=121, with 120 providing data) effects. Side effects during and after the acupuncture treatments were registered in structured treatment protocols and study diaries. No serious complications occurred. Side effects during the acupuncture sessions included minor bleeding in 5.0%, tiredness in 4.9%, numbness in 4.5% and dizziness in 1.4% of the 1298 treatments. After treatment, the mean proportions of participants reporting side effects each week were: tiredness 25.8%; feeling cold 17.8%; dizziness 9.7%; sweating 9.3%; haematoma 8.8%; and soreness at the needling sites 4.3%. Participants perceived the needling to be not painful (47.4% of participants), or mildly (39.1%), moderately (11.6%) or very painful (1.4%). Few side effects occurred and those that did were mild. Nearly 90% found PC6 acupuncture to be not painful or only mildly painful. Healthcare professionals may consider the observed levels of side effects when informing patients about side effects of PC6 acupuncture. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Side-gate modulation effects on high-quality BN-Graphene-BN nanoribbon capacitors
DOE Office of Scientific and Technical Information (OSTI.GOV)
Wang, Yang; Chen, Xiaolong; Ye, Weiguang
High-quality BN-Graphene-BN nanoribbon capacitors with double side-gates of graphene have been experimentally realized. The double side-gates can effectively modulate the electronic properties of graphene nanoribbon capacitors. By applying anti-symmetric side-gate voltages, we observed significant upward shifting and flattening of the V-shaped capacitance curve near the charge neutrality point. Symmetric side-gate voltages, however, only resulted in tilted upward shifting along the opposite direction of applied gate voltages. These modulation effects followed the behavior of graphene nanoribbons predicted theoretically for metallic side-gate modulation. The negative quantum capacitance phenomenon predicted by numerical simulations for graphene nanoribbons modulated by graphene side-gates was not observed,more » possibly due to the weakened interactions between the graphene nanoribbon and side-gate electrodes caused by the Ga{sup +} beam etching process.« less
Disaster preparedness of dialysis patients for Hurricanes Gustav and Ike 2008.
Kleinpeter, Myra A
2009-01-01
Hurricanes Katrina and Rita resulted in massive devastation of the Gulf Coast at Mississippi, Louisiana, and Texas during 2005. Because of those disasters, dialysis providers, nephrologists, and dialysis patients used disaster planning activities to work to mitigate the morbidity and mortality associated with the 2005 hurricane season for future events affecting dialysis patients. As Hurricane Gustav approached, anniversary events for Hurricane Katrina were postponed because of evacuation orders for nearly the entire Louisiana Gulf Coast. As part of the hurricane preparation, dialysis units reviewed the disaster plans of patients, and patients made preparation for evacuation. Upon evacuation, many patients returned to the dialysis units that had provided services during their exile from Hurricane Katrina; other patients went to other locations as part of their evacuation plan. Patients uniformly reported positive experiences with dialysis providers in their temporary evacuation communities, provided that those communities did not experience the effects of Hurricane Gustav. With the exception of evacuees to Baton Rouge, patients continued to receive their treatments uninterrupted. Because of extensive damage in the Baton Rouge area, resulting in widespread power losses and delayed restoration of power to hospitals and other health care facilities, some patients missed one treatment. However, as a result of compliance with disaster fluid and dietary recommendations, no adverse outcomes occurred. In most instances, patients were able to return to their home dialysis unit or a nearby unit to continue dialysis treatments within 4 - 5 days of Hurricane Gustav. Hurricane Ike struck the Texas Gulf Coast near Galveston, resulting in devastation of that area similar to the devastation seen in New Orleans after Katrina. The storm surge along the Louisiana Gulf Coast resulted in flooding that temporarily closed coastal dialysis units. Patients were prepared and experienced minimal interruption of dialysis services. Early planning and evacuation in the face of hurricane landfall--lessons learned from Hurricane Katrina in 2005--prevented disruption of treatment.
Subjective experience and mental side-effects of antipsychotic treatment.
Gerlach, J; Larsen, E B
1999-01-01
Many schizophrenic patients have a negative attitude towards antipsychotic drugs. This attitude is not only due to lack of insight into the disease, lack of recognition of the beneficial effects of the drugs, and to objective side-effects. The negative attitude is to a high degree due to mental side-effects and a sceptical opinion about antipsychotic medication in general. In a study of 53 chronic schizophrenic out-patients receiving maintenance depot antipsychotic treatment, we found that 60% were positive about the treatment, 32% were ambivalent and 8% had a negative attitude. Only 60% complained of side-effects, even though 94% had objective side-effects. Mental side-effects such as subjective akathisia, dysphoria and emotional indifference were most often observed by the patients, while hypokinesia and hyperkinesia were least noticed by them, but most often observed by the physician. No correlation was found between the patients' subjective assessment of their quality of life and the degree of psychosis and side-effects. With the new atypical antipsychotics this situation seems to be changing. These new drugs are primarily characterized by a lower level of motor extrapyramidal side-effects (EPS), and with fewer motor EPS, fewer mental EPS can be expected. In recent studies comparing the new antipsychotics with haloperidol, better effects have been observed with regard to negative symptoms and depression, and this may at least in part be a reflection of a lower level of mental side-effects of the atypical antipsychotics. This improved clinical profile of new antipsychotics is extremely valuable in the context of an integrated treatment in schizophrenia, consisting of early intervention, psychosocial rehabilitation and family/patient psycho-education.

Drop-out is a core problem in opioid maintenance treatment (OMT), but patients' reactions to and acceptance of the various OMT medications are insufficiently investigated. In Norway, there has been vocal patient resistance to the newest medication, buprenorphine-naloxone (BNX), and complaints have focused on the side effect profile. There has been no comparison of patient satisfaction and side effects of the three most common OMT medications. To compare patient satisfaction with OMT and side effects of BNX, buprenorphine monopreparate (BUP), and methadone (MET) as reported by patients. Data were drawn from a national peer-to-peer survey developed by a patient advocacy group. The survey engaged more than 1000 OMT patients, corresponding to one seventh of OMT patients in Norway. The associations between side effects, treatment satisfaction, and patient characteristics were tested in multinomial logistic regressions. High patient satisfaction with OMT overall was reported despite lower satisfaction with medication itself and widely prevalent side effects. Among each medication group, dissatisfaction with medications or OMT in general along with poor health status increased the relative risk ratio of reporting the heaviest side effect burden. MET users reported the highest side effect burden and BNX users the lightest, but BNX users were more dissatisfied with their medication. Side effects are a concern for nearly all OMT patients, and they do not appear to accumulate with age or length of treatment. BNX users' dissatisfaction with their medication is of particular concern, and expectations and preferences of medication may be influencing their dissatisfaction. Copyright © 2018.

Patients with major depression discontinue taking their antidepressants for many reasons. Although side effects are often cited as the reason for discontinuation, few prospective studies have addressed this question, and none has specifically examined discontinuation in patients with severe depression. Inpatients and outpatients treated with a selective serotonin reuptake inhibitor for major depressive disorder were identified after admission. Three months later, patients were contacted and interviewed to determine antidepressant usage and the side effects experienced, including when these were experienced and their severity. Between October 2001 and April 2003, 406 English- or Spanish-speaking patients aged 18 to 75 years were followed up. One in 4 patients discontinued the index antidepressant. Among specific side effects noted, only "change in weight" and "anxiety" were significant predictors of discontinuation after controlling for confounders. Experiencing 1 or more "extremely" bothersome side effects was associated with more than a doubling of the risk of discontinuation, but the presence of side effects and side effects less severe than "extremely" bothersome were not significant predictors. There were no differences among selective serotonin reuptake inhibitor antidepressants in either the presence/absence of side effects or in the discontinuation rates. The results suggest that the contribution of side effects to antidepressant discontinuation is more complex than previously suggested. Disparate findings from earlier studies may reflect aspects of study design, such as examining populations whose severity of depression varied widely or not controlling for important confounding factors. Future research should separately examine high-risk groups (or control for severity of depression) and carefully rule out other potential contributors to discontinuation.
Effects of side lying on lung function in older individuals.

Body positioning exerts a strong effect on pulmonary function, but its effect on other components of the oxygen transport pathway are less well understood, especially the effects of side-lying positions. This study investigated the interrelationships between side-lying positions and indexes of lung function such as spirometry, alveolar diffusing capacity, and inhomogeneity of ventilation in older individuals. Nineteen nonsmoking subjects (mean age=62.8 years, SD=6.8, range=50-74) with no history of cardiac or pulmonary disease were tested over 2 sessions. The test positions were sitting and left side lying in one session and sitting and right side lying in the other session. In each of the positions, forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), single-breath pulmonary diffusing capacity (DLCO/VA), and the slope of phase III (DN2%/L) of the single-breath nitrogen washout test to determine inhomogeneity of ventilation were measured. Compared with measurements obtained in the sitting position, FVC and FEV1 were decreased equally in the side-lying positions, but no change was observed in DLCO/VA or DN2%/L. Side-lying positions resulted in decreases in FVC and FEV1, which is consistent with the well-documented effects of the supine position. These findings further support the need for prescriptive rather than routine body positioning of patients with risks of cardiopulmonary compromise and the need to use upright positions in which lung volumes and capacities are maximized.

Prenatal cocaine exposure and neonatal/infant outcomes.
Cambell, Shelly
2003-01-01
Illegal drug use throughout the nation is a problem of epidemic proportion. Of particular concern is drug use among pregnant women. In most cases, these women have little hope of achieving a better life for themselves or their children. Illegal drugs, cocaine in particular, can have devastating effects on the neonate. These effects can last well into childhood and can exhibit themselves in academic, social, and family situations. Challenges for the neonatal nurse include early identification of these infants and use of available resources. This article addresses prenatal cocaine use and support services for drug-dependent women, effects of cocaine during the neonatal period, possible neonatal and infant outcomes, and implications for nursing practice.
Predicting new drug indications from network analysis

This work adapts centrality measures commonly used in social network analysis to identify drugs with better positions in drug-side effect network and drug-indication network for the purpose of drug repositioning. Our basic hypothesis is that drugs having similar phenotypic profiles such as side effects may also share similar therapeutic properties based on related mechanism of action and vice versa. The networks were constructed from Side Effect Resource (SIDER) 4.1 which contains 1430 unique drugs with side effects and 1437 unique drugs with indications. Within the giant components of these networks, drugs were ranked based on their centrality scores whereby 18 prominent drugs from the drug-side effect network and 15 prominent drugs from the drug-indication network were identified. Indications and side effects of prominent drugs were deduced from the profiles of their neighbors in the networks and compared to existing clinical studies while an optimum threshold of similarity among drugs was sought for. The threshold can then be utilized for predicting indications and side effects of all drugs. Similarities of drugs were measured by the extent to which they share phenotypic profiles and neighbors. To improve the likelihood of accurate predictions, only profiles such as side effects of common or very common frequencies were considered. In summary, our work is an attempt to offer an alternative approach to drug repositioning using centrality measures commonly used for analyzing social networks.

Among their beneficial effects, non-steroidal anti-inflammatory drugs may also exert several side effects which depend on the dosage and the type of these medications. The most frequent gastrointestinal side effects usually develop shortly after the beginning of their administration, but others such as cardiovascular interactions (which are present much less frequently than gastrointestinal side effects) can also occur after the beginning of drug administration without a latency period. For a long-term treatment, non-steroidal anti-inflammatory drugs are most frequently used in the elderly population where patients typically have high cardiovascular risk and take other medicines, e.g. low dose acetylsalicylic acid that can interact with non-steroidal anti-inflammatory drugs; in this aspect diclofenac may cause less side effects. In this review, the authors briefly review cardiovascular side effects of non-steroidal anti-inflammatory drugs, the processes which potentially influence them, therapeutic consequences and their interaction with acetylsalicylic acid.

In 2006 Nolvadex was discontinued and replaced by a variety of alternative generic tamoxifen brands for the adjuvant treatment of breast cancer. Anecdotally, patients are switching brands and taking alternative medications to reduce treatment related symptoms. Nevertheless, more severe side effects may equate to better relapse prevention. This study evaluates generic tamoxifen adherence and its correlation with side effects and brand switch. Consecutive disease free ER positive patients (stage I-III) were invited to respond to a questionnaire. 165 of 327 questionnaires were returned (50% response). Pearson's Chi Square test was used for data analysis. 63 patients (38%) reported a switch between generic tamoxifen. 59% of all patients experienced side effects associated with tamoxifen treatment of which 53% were severe. Patients experiencing differential symptoms dependent on tamoxifen brand reported more severe side effects (p = 0.02). Non-prescribed supplements were taken by 42% of all patients with no significant improvement in climacteric symptoms (p = 0.05). The concomitant use of SSRIs appeared to have no effect on symptoms. A significant number of patients considered discontinuing tamoxifen because of the side effects (p = 0.001), yet this did not translate into discontinuation or non-adherence (p = 0.8 and 0.08 respectively). Severe tamoxifen side effects are commonly experienced by breast cancer patients and can be significantly altered by change in tamoxifen brand. Most patients will continue to take tamoxifen, despite side effects to avoid cancer relapse. Supplementation and antidepressants did not improve tamoxifen related side effects in our cohort.

OBJECTIVE To examine the association between treatment-related side effects and cancer-specific and general quality of life (QOL) among long-term prostate cancer survivors. MATERIALS AND METHODS Within the Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial, we conducted telephone interviews with prostate cancer survivors (N = 518) who were 5-10 years after diagnosis. We assessed demographic and clinical information, sexual, urinary, and bowel treatment-related side effects (Expanded Prostate Cancer Index Composite), cancer-specific QOL (Functional Assessment of Cancer Therapy—total score), and general QOL (the Medical Outcomes Study Short Form 12’s physical and mental subscales). RESULTS Participants were aged 74.6 years on average, primarily White (88.4%), and married (81.7%). Pearson correlation coefficients between the 3 treatment-related side effect domains (urinary, sexual, and bowel) and QOL ranged between 0.14 and 0.42 (P <.0001). Multivariable linear regression analyses revealed that poorer urinary and sexual functioning and greater bowel side effects were independently associated with poorer cancer-specific QOL (P <.0001). Bowel and urinary functions were also associated with poorer general QOL on the Medical Outcomes Study Short Form 12’s physical component summary and mental component summary (P <.05). Bowel side effects demonstrated the strongest association with all QOL outcomes. CONCLUSION Treatment-related side effects persisted for up to 10 years after diagnosis and continued to be associated with men’s QOL. These results suggest that each of the treatment-related side effects was independently associated with cancer-specific QOL. Compared with the other Expanded Prostate Cancer Index Composite domains, bowel side effects had the strongest association with cancer-specific and general QOL. These associations emphasize the tremendous impact that bowel side effects continue to have for men many years after their initial diagnosis. PMID:24975711
Consumer confusion between prescription drug precautions and side effects.

Multiple studies have identified consumers' difficulty correctly interpreting risk information provided about prescription drugs, whether in printed format or online. This study's purpose was to explore whether consumers can distinguish between prescription drug precautions and side effects presented on brand-name drug websites. Participants (n=873) viewed fictitious drug websites that presented both precautions and side effects for one of four drugs, and they completed a survey assessing recall and comprehension. We coded open-ended recall data to identify whether drug precautions were mentioned and, if so, how they were interpreted. Approximately 15% of participants mentioned at least one drug precaution. The majority (59.7%) misinterpreted precautions as potential side effects. Participants who misinterpreted precautions rated the drugs as significantly more likely to cause side effects than participants who accurately interpreted the precautions. Age, education, literacy, and other factors did not appear to predict precaution interpretation. At least some consumers are likely to interpret precautions on drug websites as potential side effects, which might affect consumer preferences, treatment decisions, and medication safety. Healthcare providers should be aware of this potential confusion, assess patients' understanding of precautions and potential side effects, and address any misunderstandings.

This retrospective case series describes ocular side-effects associated with imatinib mesylate (Gleevec) and the clinical characteristics of these adverse reactions. A chart review of 104 patients on imatinib mesylate therapy from Oregon Health & Science University's Cancer Center were studied with regard to ocular side-effects. In addition, spontaneous reports from the Food and Drug Administration, the World Health Organization, and the National Registry of Drug-Induced Ocular Side-Effects databases were reviewed, including a Medline literature search. Seventy-three (70%) of the patients at OHSU developed periorbital edema and 19 patients (18%) developed epiphora after receiving imatinib mesylate. Average dose was 407.5+/-60 mg. Periorbital edema occurred an average of 68+/-48 days after initiation of therapy. WHO classification of side-effects is as follows: certain: periorbital edema; probable: epiphora; possible: extraocular muscle palsy, ptosis, blepharoconjunctivitis; unlikely: glaucoma, papilledema, retinal hemorrhage, photosensitivity, abnormal vision, and increased intraocular pressure. Periorbital edema and epiphora are the two most common ocular side-effects related to imatinib mesylate therapy. Clinical characteristics of imatinib mesylate induced periorbital edema are described. Management of ocular side-effects is conservative except in very rare cases of visually significant periorbital edema.
Fast image decompression for telebrowsing of images

Progressive image transmission (PIT) is often used to reduce the transmission time of an image telebrowsing system. A side effect of the PIT is the increase of computational complexity at the viewer's site. This effect is more serious in transform domain techniques than in other techniques. Recent attempts to reduce the side effect are futile as they create another side effect, namely, the discontinuous and unpleasant image build-up. Based on a practical assumption that image blocks to be inverse transformed are generally sparse, this paper presents a method to minimize both side effects simultaneously.

Second-generation antipsychotic (SGA) medications introduced about 20 years ago are increasingly used to treat psychiatric illnesses in children and adolescents. There has been a five-fold increase in the use of these medications in U.S. children and adolescents in the past decade. However, there has also been a parallel rise in the incidence of side effects associated with these medications, such as obesity, dyslipidemia, insulin resistance, and diabetes mellitus. Despite the severity of these complications and their financial impact on the national healthcare budget, there is neither a clear understanding of the mechanisms contributing to these side effects nor the best ways to address them. Studies that examined lifestyle modification and pharmaceutical agents have yielded mixed results. Therefore, clinical studies using agents, such as vitamin D, which are inexpensive, readily available, with low side effects profile, and have mechanisms to counteract the metabolic side effects of SGA agents, are warranted. Vitamin D is a prohormone with skeletal and extraskeletal properties that could potentially reduce the severity of these metabolic side effects. Its role as an adjunctive therapy for the management of metabolic side effects of SGA agents has not been adequately studied. Effective strategies to curb these side effects will improve the overall health of youths with psychiatric illnesses who receive SGAs. Herein we present a pilot study on the use of vitamin D in patients on treatment with SGAs. PMID:22145446

Patients with treatment-resistant obsessive-compulsive disorder (OCD) are potential candidates for deep brain stimulation (DBS). The anteromedial subthalamic nucleus (STN) is among the most commonly used targets for DBS in OCD. We present a patient with a 30-year history of treatment-resistant OCD who underwent anteromedial STN-DBS. Despite a clear mood-enhancing effect, stimulation caused motor side effects, including bilateral hyperkinesia, dyskinesias, and sudden large amplitude choreatic movements of arms and legs when stimulating at voltages greater than approximately 1.5 V. DBS at lower amplitudes and at other contact points failed to result in a significant reduction of obsessions and compulsions without inducing motor side effects. Because of this limitation in programming options, we decided to reoperate and target the ventral capsule/ventral striatum (VC/VS), which resulted in a substantial reduction in key obsessive and compulsive symptoms without serious side effects. Choreatic movements and hemiballismus have previously been linked to STN dysfunction and have been incidentally reported as side effects of DBS of the dorsolateral STN in Parkinson disease (PD). However, in PD, these side effects were usually transient, and they rarely interfered with DBS programming. In our patient, the motor side effects were persistent, and they made optimal DBS programming impossible. To our knowledge, such severe and persistent motor side effects have not been described previously for anteromedial STN-DBS. Copyright © 2017 Elsevier Inc. All rights reserved.

In a clinical trial of two antirheumatic agents two methods of collection of side effects were used, one with and the other without a check list of possible symptoms. Findings suggested that the use of a check list interfered with the collection of side effects. Known side effects of aspirin—tinnitus, deafness, and gastrointestinal disturbance—were more efficiently shown and symptoms not included in the check list were more likely to be reported when a check list was not used.

Regional source tsunamis pose a potentially devastating hazard to communities and infrastructure on the New Zealand coast. But major events are very uncommon. This dichotomy of infrequent but potentially devastating hazards makes realistic assessment of the risk challenging. Here, we describe a method to determine a probabilistic assessment of the tsunami hazard by regional source tsunamis with an "Average Recurrence Interval" of 2,500-years. The method is applied to the east Auckland region of New Zealand. From an assessment of potential regional tsunamigenic events over 100,000 years, the inundation of the Auckland region from the worst 100 events is modelled using a hydrodynamic model and probabilistic inundation depths on a 2,500-year time scale were determined. Tidal effects on the potential inundation were included by coupling the predicted wave heights with the probability density function of tidal heights at the inundation site. Results show that the more exposed northern section of the east coast and outer islands in the Hauraki Gulf face the greatest hazard from regional tsunamis in the Auckland region. Incorporating tidal effects into predictions of inundation reduced the predicted hazard compared to modelling all the tsunamis arriving at high tide giving a more accurate hazard assessment on the specified time scale. This study presents the first probabilistic analysis of dynamic modelling of tsunami inundation for the New Zealand coast and as such provides the most comprehensive assessment of tsunami inundation of the Auckland region from regional source tsunamis available to date.
Wildfire Policy in Mediterranean France: How Far is it Efficient and Sustainable?
Curt, Thomas; Frejaville, Thibaut
2018-03-01
A new fire policy reinforcing aggressive fire suppression was established in Mediterranean France in response to the devastating wildfires of the 1990s, but to what extent this has changed fire activity yet remains poorly understood. For this purpose, we compared the number and location of ignitions and of burned areas between two 20-year periods (1975-1994 vs. 1995-2014), in parallel to the changes in fuel covering, human activity promoting ignitions, and fire weather. The number of fires decreased almost continuously since 1975, but sharply after 1994, suggesting an effect of better fire prevention due to the new policy. But the major change in fire activity is a considerable reduction in fire size and burned areas after 1994, especially during summer and in the most fire-prone places, in response to massive efforts put into fire suppression. These reductions have occurred while the covering by fuel biomass, the human pressure on ignition, and the fire weather index increased, thus making the study area more hazardous. Our results suggest that a strategy of aggressive fire suppression has great potential for counterbalancing the effects of climate changes and human activities and for controlling fire activity in the short term. However, we discuss whether such a suppression-oriented approach is sustainable in the context of global changes, which cast new fire challenges as demonstrated by the devastative fires of 2003 and 2016. We advocate for a more comprehensive fire policy to come. © 2017 Society for Risk Analysis.

The 18th and early 19th century river maps are important data sources for studying past landscapes. This is not only as a result of improved surveying techniques, but also because they depict landscape during probably the most important climatic and land-use changes since the Middle Ages. In this phase of the increased river activity during the last onset of the so-called Little Ice Age period, several major flood events occured. Local manuscript maps, which often depict the channel in major detail, help us to obtain a better understanding of their geomorphic and other impacts. The catastrophic ice flood, which occured on the Middle Danube river at the end of January 1809 was undoubtedly the most disastrous event of its kind in Slovakia, although it also hit a number of settlements in Lower Austria and Hungary. Several people drowned and the flood also resulted in great damage to settlements and livestock. Devastating effects of this flood particularly as to the towns of Bratislava and Komárno/Komárom were comparable with effects of disastrous floods of February 1830 in Vienna (Austria), March 1838 in Buda/Pest (Hungary) or 1845 flood in Prague (Czech Republic), respectively. In case of the present Slovakian capital Bratislava, on January 29, 1809, two ice barriers suddenly rose the water up to 10 m above the zero level and the river quickly overflowed its banks inundating the low-lying parts of the town. The flood blacked out communications with neighbouring regions. Record-breaking height of water led to breaches of the important right-bank embankment (constructed in 1770s). Through several openings water flooded the right bank, almost completely destroying the adjacent village of Petržalka/Engerau. The damage to Vienna highway levee was so massive that it only could be repaired 16 years later, in 1825-6 (although this was also due to Napoleonic wars). The flood also reactivated the Chorvátske rameno anabranch, 33 years after its abandonment. A number of local manuscript maps depict the river before and after this event. Combined with written literary reports, the maps allow us to describe the course, the devastating effects and the aftermath consequences of the 1809 flood precisely, particularly as to the territory of the city of Bratislava itself. Moreover, many of these maps comprise a wealth of information about flood in their detailed explanatory legends and remarks. The most important maps and plans are those currently deposited in the National Archives of Hungary (= maps from the collection of former Governing Council, the central supervisory authority of the Habsburgs for the Hungarian Kingdom), in the Municipial Archives of Bratislava and the Slovak National Archives, respectively. Effects of the 1809 ice flood, as evidenced by historical maps and plans, can be generally summarised as follows: a) direct destruction (by ice floes) or collapse of houses, bridges, buildings, boat mills, groynes and bank revetments b) heavy lateral erosion of the river channel during this single event (then referred to as „damage to banks") c) breaches of protective dikes d) formation of new water bodies - temporary lakes - created by spilled water on the landside of levees e) reactivation of upstream entrances of some side channels f) pronounced changes of flooplain configuration g) damage to floodplain forest. This research was supported by the Slovak Scientific Grant agency VEGA (Project N. 1/0362/09).

Photothermal destruction of hair shaft melanin with intense pulsed light (IPL) and neodymium:yttrium-aluminum-garnet (Nd:YAG) laser has become an effective treatment of hair removal. Our aim was to compare efficacy, satisfactory levels, safety, and side effects of Nd:YAG and IPL in hair reduction. This was a prospective randomized intrapatient, right-left, assessor-blinded comparison of Nd:YAG vs IPL. There were 38 volunteers recruited. Seven sessions were performed. Hair count, efficacy, and side effects were compared before and after each treatment and 6 months after the last treatment. In respect of 12 volunteers, we have examined the reduction in hair after 18 months. Initially, there was no significant difference between the numbers of hair follicles. There was significant hair reduction after each treatment on the Nd:YAG-treated side. The hair reduction became significant after the third treatment with IPL. Comparison of the efficacy of the two devices on each visits showed no significant difference. There was statistically lower pain score on the IPL-treated side and statistically higher erythema, burning sensation, and edema on the Nd:YAG-treated side. Statistically lower side effect score was observed on the IPL-treated side. Eight months after the last treatment, there was significant hair reduction both on the Nd:YAG and on the IPL-treated side, and there was no difference between the efficacy. The patient satisfaction scores were higher with the IPL. Unwanted hair can be reduced by both systems safely and effectively; however, IPL has less side effects and higher satisfaction scores. © 2017 Wiley Periodicals, Inc.

Allergen-specific immunotherapy is the only causal form of therapy for IgE-mediated allergic diseases. Subcutaneous immunotherapy (SCIT) is considered safe and well tolerated in adults, yet there is less evidence of safety in the pediatric population. A non-interventional prospective observing longitudinal study was carried out to determine the incidence of local and systemic side effects by SCIT, routinely performed in pediatric patients. A total of 581 pediatric patients were observed in 18 study centers between March 2012 and October 2014, recording 8640 treatments and 10 015 injections. A total of 54.6% of the patients experienced immediate local side effects at least once; delayed local side effects were seen in 56.1%. Immediate systemic adverse reactions occurred in 2.2% of patients; 7.4% experienced delayed systemic side effects. However, severe systemic side effects (grade III in the classification of Ring and Messmer) were seen in 0.03% of all treatments, all appearing within 30 minutes after the injections. No grade IV reactions were observed. In addition, many potential risk factors were investigated, yet only a few were found to be associated with the occurrence of side effects. Subcutaneous immunotherapy is a safe form of therapy in pediatric patients, with similar rates of local side effects compared to adult patients and low rates of severe systemic side effects. However, local and systemic reactions occurring later than 30 minutes after injection were observed more often than expected, which makes it essential to be attentive on behalf of pediatricians, patients, and parents. © 2017 EAACI and John Wiley and Sons A/S.

Follow-up after breast cancer treatment is standard due to the risk of development of new primary cancers and recurrent disease. The aim of the present study was to evaluate a standard follow-up program in an oncological department by assessing: (1) Symptoms or signs of new primary cancer or recurrent disease, (2) Disease- and treatment-related physical and psychosocial side or late effects, and (3) relevant actions by oncology staff. In a cross-sectional study, 194 women who came for follow-up visit after treatment for primary surgery were included. The clinical oncologists registered symptoms and signs of recurrent disease or new primary cancer. Side or late effects were both assessed by patient and the clinical oncologists. Loco-regional or distant signs of recurrent disease were suspected in eight (5%) patients. Further examinations revealed no disease recurrence. Most patients (93%) reported some degree of side or late effects. Statistically significant more side or late effects were reported by the women (average: 6.9) than registered by the clinical oncologists (average: 2.4), p < 0.001. The three most often patient-reported side or late effects were hot flushes (35%), fatigue (32%), and sleep disturbance (31%). None of the scheduled or additional visits resulted in detection of recurrent disease. Furthermore, the majority of patients reported side or late effects. Statistically significant more women reported side or late effects than registered by the clinical oncologists. This suggests the need for rethinking of the follow-up programs with more emphasis upon side or late effects of the treatment.

Objective Patient expectancies are hypothesized to contribute to the efficacy and side effects of psychiatric treatments, but little research has investigated this hypothesis in the context of psychopharmacological therapies for anxiety. We prospectively investigated whether expectancies predicted efficacy and adverse events in oral therapy for Generalized Anxiety Disorder (GAD), controlling for confounding patient characteristics correlating with outcomes. Methods Expectancies regarding treatment efficacy and side effects were assessed at baseline of an eight week open-label phase of a trial of chamomile for Generalized Anxiety Disorder (GAD). The primary outcome was patient-reported GAD-7 scores, with clinical response and treatment-emergent side-effects as secondary outcomes. Expectancies were used to predict symptomatic and side-effect outcomes. Results Very few baseline patient characteristics predicted either type of expectancy. Controlling for a patient’s predicted recovery based on their baseline characteristics, higher efficacy expectancies at baseline predicted greater change on the GAD-7 (adjusted β = −0.19, p = 0.011). Efficacy expectancies also predicted a higher likelihood of attaining clinical response (adjusted odds ratio = 1.69, p = 0.002). Patients with higher side effect expectancies reported more side effects (adjusted log expected count = 0.26, p = 0.038). Efficacy expectancies were unrelated to side effect reports (log expected count = −0.05, p = 0.680), and side effect expectancies were unrelated to treatment efficacy (β = 0.08, p = 0.306). Conclusions Patients entering chamomile treatment for GAD with more favorable self-generated expectancies for the treatment experience greater improvement and fewer adverse events. Aligning patient expectancies with treatment selections may optimize outcomes. PMID:27716513
[Extrapyramidal side-effects: avoidance, diagnosis and treatment].
Fleischhacker, W Wolfgang; Widschwendter, Christian
2005-04-01
Acute extrapyramidal side-effects (EPS) are a common phenomenon of treatment with antipsychotics. They are associated with a substantial reduction of the patient's quality of life and of compliance with the treatment. This article gives an overview of the different forms of EPS. It outlines strategies to avoid these side-effects and discusses problems in diagnosis and treatment. In comparison to conventional compounds, the clearest advantage of new generation antipsychotics is a reduced risk of the occurrence of extrapyramidal side-effects (EPS). Many studies have found that newer antipsychotics have a lesser propensity to causes EPS. Nevertheless, there are some conflicting results on this topic. This article discusses some of these results and sheds light on methodological problems in the evaluation of side-effects of antipsychotic treatment.
Epidemiology of a thermonuclear bomb-burst over Nashville, Tennessee: a theoretic study.
Quinn, R W
1983-07-01
A thermonuclear bomb explosion over any city in the world would have a devastating effect on the population and environment. For those who survive, with or without injuries, life would become primitive with little or no uncontaminated food or water, and with inadequate housing, fuel, and medical care, resulting in a breakdown of family and interpersonal relationships. This theoretic study of the potential outcome of a thermonuclear bomb-burst over Nashville, Tennessee, discusses epidemiologically the wide range of medical and psychologic effects from the direct trauma of blast and fire, widespread epidemics of otherwise controlled disease, long-term chronic illness, genetic damage, and catastrophic environmental havoc.
Overview of exposure to and effects from radionuclides in terrestrial and marine environments.

The accident at the Fukushima Daiichi nuclear power plant, precipitated by the devastating earthquake and subsequent tsunami that struck the northeastern coast of Japan in March 2011, has raised concerns about potential impacts to terrestrial and marine environments from radionuclides released into the environment. A preliminary understanding of the potential ecological impacts from radionuclides can be ascertained from observations and data developed following previous environmental incidents elsewhere in the world. This article briefly summarizes how biota experience exposure to ionizing radiation, what effects may be produced, and how they may differ among taxa and habitats. Copyright © 2011 SETAC.
Oral health impacts of medications used to treat mental illness.

Many psychotropic medications affect oral health. This review identified oral side effects for antidepressant, antipsychotic, anticonvulsant, antianxiety and sedative drugs that are recommended in Australia for the management of common mental illnesses and provides recommendations to manage these side-effects. The Australian Therapeutic Guidelines and the Australian Medicines Handbook were searched for medications used to treat common mental health conditions. For each medication, the generic name, class, and drug company reported side-effects were extracted from the online Monthly Index of Medical Specialties (eMIMs) and UpToDate databases. Meyler's Side Effect of Drugs Encyclopaedia was used to identify additional oral adverse reactions to these medications. Fifty-seven drugs were identified: 23 antidepressants, 22 antipsychotics or mood stabilisers, and 12 anxiolytic or sedative medications. Xerostomia (91%) the most commonly reported side effect among all classes of medications of the 28 identified symptoms. Other commonly reported adverse effects included dysguesia (65%) for antidepressants, and tardive dyskinesia (94%) or increased salivation (78%) for antipsychotic medications. While xerostomia has often been reported as a common adverse effect of psychotropic drugs, this review has identified additional side effects including dysguesia from antidepressants and tardive dyskinesia and increased salivation from antipsychotics. Clinicians should consider oral consequences of psychotropic medication in addition to other side-effects when prescribing. For antidepressants, this would mean choosing duloxetine, agomelatine and any of the serotonin re-uptake inhibitors except sertraline. In the case of antipsychotics and mood stabilisers, atypical agents have less oral side effects than older alternatives. Copyright © 2017 Elsevier B.V. All rights reserved.
Predicting drug side-effect profiles: a chemical fragment-based approach
2011-01-01
Background Drug side-effects, or adverse drug reactions, have become a major public health concern. It is one of the main causes of failure in the process of drug development, and of drug withdrawal once they have reached the market. Therefore, in silico prediction of potential side-effects early in the drug discovery process, before reaching the clinical stages, is of great interest to improve this long and expensive process and to provide new efficient and safe therapies for patients. Results In the present work, we propose a new method to predict potential side-effects of drug candidate molecules based on their chemical structures, applicable on large molecular databanks. A unique feature of the proposed method is its ability to extract correlated sets of chemical substructures (or chemical fragments) and side-effects. This is made possible using sparse canonical correlation analysis (SCCA). In the results, we show the usefulness of the proposed method by predicting 1385 side-effects in the SIDER database from the chemical structures of 888 approved drugs. These predictions are performed with simultaneous extraction of correlated ensembles formed by a set of chemical substructures shared by drugs that are likely to have a set of side-effects. We also conduct a comprehensive side-effect prediction for many uncharacterized drug molecules stored in DrugBank, and were able to confirm interesting predictions using independent source of information. Conclusions The proposed method is expected to be useful in various stages of the drug development process. PMID:21586169

(1) determine which antipsychotic side effects (SE) schizophrenic patients consider the most distressing during treatment with typical antipsychotics, (2) measure the impact of actual and past SE on patients' attitude toward antipsychotics and (3) assess the influence of both on adherence. The 213 schizophrenics, treated with conventional antipsychotics, were recruited in two psychiatric hospitals in Hamburg. Subjects were assessed about type and severity of present and past side effects and their attitude and adherence to antipsychotic treatment. The 82 (39%) patients presented present SE while 131 (61%) did not. Sexual dysfunctions (P < 0.001), extrapyramidal (P < 0.05) and psychic side effects (P < 0.05) were rated as significantly subjectively more distressing than sedation or vegetative side effects. Patients presenting with present SE compared with patients without present SE had a significantly more negative general attitude toward antipsychotics (P < 0.05), were more doubtful about their efficacy (P < 0.01) and were less likely to encourage a relative to take such a medication in case of need (P < 0.001). A regression analysis indicated that nonadherence was mainly influenced by negative general and efficacy attitudes toward antipsychotics and the experience of past or present antipsychotic side effects. All antipsychotic side effects, present or past, can have a durable negative impact on patient's attitude toward antipsychotic treatment and adherence. Non-adherence is mainly determined, among other factors, by these negative attitudes, which are partly influenced by the experience of past or present antipsychotic-induced side effects.

Retinopathy of Prematurity (ROP) is a common retinal neovascular disorder of premature infants. It is of variable severity, usually heals with mild or no sequelae, but may progress to blindness from retinal detachments or severe retinal scar formation. This is a preliminary report of the effectiveness and safety of a new and original use of topical ketorolac in preterm newborn to prevent the progression of ROP to the more severe forms of this disease. From January 2001 to December 2002, all fifty nine preterm newborns with birthweight less than 1250 grams or gestational age less than 30 weeks of gestational age admitted to neonatal intensive care were eligible for treatment with topical ketorolac (0.25 milligrams every 8 hours in each eye). The historical comparison group included all 53 preterm newborns, with the same inclusion criteria, admitted between January 1999 and December 2000. Groups were comparable in terms of weight distribution, Apgar score at 5 minutes, incidence of sepsis, intraventricular hemorrhage and necrotizing enterocolitis. The duration of oxygen therapy was significantly longer in the control group. In the ketorolac group, among 43 children that were alive at discharge, one (2.3%) developed threshold ROP and cryotherapy was necessary. In the comparison group 35 children survived, and six child (17%) needed cryotherapy (Relative Risk 0.14, 95%CI 0.00 to 0.80, p = 0.041). Adjusting by duration of oxygen therapy did not significantly change these results. Adverse effects attributable to ketorolac were not detected. This preliminary report suggests that ketorolac in the form of an ophthalmic solution can reduce the risk of developing severe ROP in very preterm newborns, without producing significant adverse side effects. These results, although promising, should be interpreted with caution because of the weakness of the study design. This is an inexpensive and simple intervention that might ameliorate the progression of a disease with devastating consequences for children and their families. We believe that next logical step would be to assess the effectiveness of this intervention in a randomized controlled trial of adequate sample size.

Colonoscopy is widely regarded to be the gold standard for colorectal cancer (CRC) detection. Recent studies, however, suggest that the effectiveness of colonoscopy is mostly confined to tumors on the left side of the colon (descending, sigmoid, rectum), and that the technology has poor tumor detection for right-sided (cecum, ascending, transverse) lesions. A minimally invasive test that can detect both left-sided and right-sided lesions could increase the effectiveness of screening colonoscopy by revealing the potential presence of neoplasms in the right-sided "blind spot". We previously reported on a seven-gene, blood-based biomarker panel that effectively stratifies a patient's risk of having CRC. For the current study, we assessed the effectiveness of the seven-gene panel for the detection of left- and right-sided CRC lesions. Results were evaluated for 314 patients with CRC (left-sided: TNM I, 65; TNM II, 57; TNM III, 60; TNM IV, 17; unknown, 9. right-sided: TNM I, 28; TNM II, 29; TNM III, 38; TNM IV, 12; unknown, 1 and including two samples with both left and right lesions) and 328 control samples. Blood samples were obtained prior to clinical staging and therapy. Most CRC subjects had localized disease (stages I and II, 58%); regional (stage III) and systemic (stage IV) disease represented 32% and 9%, respectively, of the study population. The panel detected left-sided (74%, 154/208) and right-sided (85%, 92/108) lesions with an overall sensitivity of 78% (215/316) at a specificity of 66% (215/328). Treatable cancer (stages I to III) was detected with left-sided lesion sensitivity of 76% (138/182) and right-sided sensitivity of 84% (80/95). This seven-gene biomarker panel detected right-sided CRC lesions across all cancer stages with a sensitivity that is at least equal to that for left-sided lesions. This study supports the use of this panel as the basis for a patient-friendly, blood-based test that can be easily incorporated into a routine physical examination in advance of colonoscopy to provide a convenient companion diagnostic and a pre-screening alert, ultimately leading to enhanced CRC screening effectiveness.

Central Europe suffered from a major multi-decadal environmental crisis from the early 1470s onwards. The turn of the 15th-16th centuries was characterised by an unusually high number of stress factors related to large-scale climate variability, amongst others locally manifested in the great increase of weather-related extremes such as the multiannual droughts of the 1470s, with further significant drought periods in the 1490s and 1500s; the extraordinary high frequency of hard winters in the 1470s-1490s, and a major flood-rich period from the late 1470s to the mid-1520s. From the human impact side, the recurrent crisis was greatly intensified by biological hazards such as plague epidemic cycles and devastating multi-annual locust invasions that gravely affected our investigated region. Wars and war-expenses further deepened this crisis. In our presentation we provide an overview of flood peaks on major Italian (e.g. Po, Adige) and Eastern-Alpine (e.g. Danube, Salzach, Traun), Carpathian-Basin (Danube, Danube catchment, Tisza catchment) rivers and river catchments, with special emphasis on great flood years (e.g. 1485, 1499, 1501, 1508 etc.). Further topics of the discussion are droughts and multiannual dry periods, together with related environmental problems (e.g. locust invasions, bad harvests) such as the one in the 1470s, the early-mid 1490s, 1503 and 1506-1507. The third major group of weather extremes in the period consists of hard winters. This and other extreme weather events, together with their (potential) socio-economic effects comprise the final major topic of discussion of the paper.

Liver transplantation (OLTx) is an optimal method of treatment of end-stage liver failure. It gives a chance to get back to an active life. 80-90% of patients survive over 1 year after liver transplantation with a perspective of a long life.Recently more attention is being paid to health related quality of life (QoL). It is considered as a combination of physical and mental condition, social and economical state and somatic experience. The aim of the study was to analyze patient's QoL after OLTx compared to the condition before OLTx. 123 patients 1-12 years after transplantation were included in the study. The study was conducted in Outpatients Clinic of Immunology, Transplantology and Internal Medicine Department and Transplantation Medicine and Nephrology Department of Warsaw Medical University between October 2007 and January 2008. Original questionnaire was used, consisting of 8 general questions and 44 detailed questions concerning pre- and posttransplant period. Information about physical condition (health, mobility, basic functions, drug side effects), mental condition (anxiety, happiness, cognition disorders), social function (family, friends, work) and economic status were gathered. "Never, sometimes, often, very often" score was used. Majority of subjects de fi ned their quality of life and physical condition before transplantation as poor, and post transplantation - as good. The respondent's mental condition didn't differ much before and after transplantation. Level of satisfaction was higher after transplantation. Health condition in some cases affected patients' family life, however it often devastated their social life before OLTx. Most patients were on disability pension and after transplantation they indicated the influence of health on their financial condition. The quality of life after liver transplantation gets better and it's de fi ned as good or very good. During the analysis of QoL a difference between conditions before and after LTX wasn't observed.

Tournasian-early Visean mud mounds (i.e., Waulsortian and Waulsortian-like mounds) are unlike other carbonate buildups in the stratigraphic record because they lack an identifiable frame-building organism. Waulsortian mounds are comprised mainly of carbonate mud; Waulsortian-like mounds are mud-rich and contain a significant percent of skeletal grains, especially crinoids and bryozoa. This study has revealed that all of the reported Waulsortian and Waulsortian-like mounds developed in low paleolatitudes either on the southern shelf margin of the Laurussian paleocontinent or in the Laurussian interior seaway. Waulsortian and Waulsortian-like mounds are specifically not present in low-latitude regions of other paleocontinents. As Tournasian-early Visean carbonatemore » deposition was widespread in the range of 30{degree}N to 10{degree}S, the very restricted paleogeographic distribution of Waulsortian and Waulsortian-like mound locations suggests a mechanism or set of conditions that effectively limited the distribution of mud mounds. Considering the Tournasian-early Visean distribution of paleocontinents and the principles that govern the movement of modern hurricanes, tropical storms, and winter storms, the tracts of hurricanes, tropical storms, and winter storms probably crossed all main submerged paleocontinental areas except the southern Laurussian shelf margin and the Laurussian interior seaway, the two areas where mud mounds developed. The lack of storm energy in these two large areas of Laurussia provided long-term stability and thus enhanced the growth prospects of the frame-deficient Waulsortian and Waulsortian-like mud mounds. Lack of extensive periodic wave reworking and other storm-induced devastation helps to account for enigmatic features such as general mound symmetry, great size, high depositional relief (as much as 220 m), and side steepness (as steep as 50{degree}).« less

Long-range economic development in Central America will depend in large part on production of indigenous mineral, energy, and water resources and on mitigation of the disastrous effects of geologic and hydrologic hazards such as landslides, earthquakes, volcanic eruptions, and floods. The region has six world-class metal mines at present as well as additional evidence of widespread mineralization. Systematic investigations using modern mineral exploration techniques should reveal more mineral deposits suitable for development. Widespread evidence of lignite and geothermal resources suggests that intensive studies could identify producible energy sources in most Central American countries. Water supply and water quality vary greatly from country to country. Local problems of ground- and surface-water availability and of contamination create a need for systematic programs to provide better hydrologic data, capital improvements, and management. Disastrous earthquakes have destroyed or severely damaged many cities in Central America. Volcanic eruptions, landslides, mudflows, and floods have devastated most of the Pacific side of Central America at one time or another. A regional approach to earthquake, volcano, and flood-risk analysis and monitoring, using modern technology and concepts, would provide the facilities and means for acquiring knowledge necessary to reduce future losses. All Central American countries need to strengthen institutions and programs dealing with earth and water resources and natural hazards. Some of these needs may be satisfied through existing or pending projects and technical and economic assistance from U.S. or other sources. The need for a comprehensive study of the natural resources of Central America and the requirements for their development is evident. The U.S. Caribbean Basin Initiative offers both an excellent opportunity for a regional approach to these pervasive problems and an opportunity for international cooperation.
Psychiatric side effects of antihypertensive drugs other than reserpine.
Paykel, E S; Fleminger, R; Watson, J P
1982-02-01
The psychiatric side effects of the major antihypertensive drugs other than reserpine are reviewed, including centrally acting drugs such as methyldopa and clonidine, peripheral adrenergic drugs such as guanethidine, beta-adrenoceptor blockers such as propranolol, and diuretics. Problems with differential diagnosis and with the interpretation of case reports make assessment of psychiatric side effects difficult. Sedation and sleep disturbances are the most common side effects, occurring with methyldopa, clonidine, and propranolol. Only methyldopa is clearly associated with depression. Other reported effects are toxic confusional states and psychotic reactions. These are rare, however, and no clear patterns of development have been recognized.

Mobile health interventions are regarded as affordable and accessible tools that can enhance standard psychiatric care. As part of the mHealth Psycho-Educational Intervention Versus Antipsychotic-Induced Side Effects (mPIVAS) project (www.psylog.eu), we developed the mobile application "PsyLOG" based on mobile "smartphone" technology to monitor antipsychotic-induced side effects. The aim of this paper is to describe the rationale and development of the PsyLOG and its clinical use. The PsyLOG application runs on smartphones with Android operating system. The application is currently available in seven languages (Croatian, Czech, English, French, German, Japanese and Serbian). It consists of several categories: "My Drug Effects", "My Life Styles", "My Charts", "My Medication", "My Strategies", "My Supporters", "Settings" and "About". The main category "My Drug Effects" includes a list of 30 side effects with the possibility to add three additional side effects. Side effects are each accompanied by an appropriate description and the possibility to rate its severity on a visual analogue scale from 0-100%. The PsyLOG application is intended to enhance the link between patients and mental health professionals, serving as a tool that more objectively monitors side-effects over certain periods of time. To the best of our knowledge, no such applications have so far been developed for patients taking antipsychotic medication or for their therapists.

Most phenotypic effects of drugs are involved in the interactions between drugs and their target proteins, however, our knowledge about the molecular mechanism of the drug-target interactions is very limited. One of challenging issues in recent pharmaceutical science is to identify the underlying molecular features which govern drug-target interactions. In this paper, we make a systematic analysis of the correlation between drug side effects and protein domains, which we call "pharmacogenomic features," based on the drug-target interaction network. We detect drug side effects and protein domains that appear jointly in known drug-target interactions, which is made possible by using classifiers with sparse models. It is shown that the inferred pharmacogenomic features can be used for predicting potential drug-target interactions. We also discuss advantages and limitations of the pharmacogenomic features, compared with the chemogenomic features that are the associations between drug chemical substructures and protein domains. The inferred side effect-domain association network is expected to be useful for estimating common drug side effects for different protein families and characteristic drug side effects for specific protein domains.

The treatment of patients with inflammatory bowel diseases has been revolutionized by the introduction of biological therapy with TNF-alpha blockers. However, TNF-alpha blockers are also associated with a wide variety of dermatological side effects, such as local skin infections, psoriasis and eczema. A new biological therapy, targeting the gut-specific adhesion molecule alpha4beta7 integrin, is the humanized monoclonal IgG1 antibody vedolizumab. Vedolizumab prevents leukocyte migration to the gastrointestinal tract, thereby reducing inflammation. This gut-specific therapy has the potential to reduce systemic side effects, including dermatological ones. We describe 3 inflammatory bowel disease patients who experience anti-TNF-alpha therapy-induced dermatological side effects, consisting of hidradenitis suppurativa, a folliculitis, scalp psoriasis and a dissecting folliculitis. In all patients, anti-TNF-alpha therapy-induced dermatological side effects diminished after switching to vedolizumab. Vedolizumab may be a viable alternative biological therapy in inflammatory bowel disease patients who experience anti-TNF-alpha therapy-induced dermatological side effects.

Experimental Study of Wake / Flap Interaction Noise and the Reduction of Flap Side Edge Noise
NASA Technical Reports Server (NTRS)
Hutcheson, Florence V.; Stead, Daniel J.; Plassman, Gerald E.
2016-01-01
The effects of the interaction of a wake with a half-span flap on radiated noise are examined. The incident wake is generated by bars of various widths and lengths or by a simplified landing gear model. Single microphone and phased array measurements are used to isolate the effects of the wake interaction on the noise radiating from the flap side edge and flap cove regions. The effects on noise of the wake generator's geometry and relative placement with respect to the flap are assessed. Placement of the wake generators upstream of the flap side edge is shown to lead to the reduction of flap side edge noise by introducing a velocity deficit and likely altering the instabilities in the flap side edge vortex system. Significant reduction in flap side edge noise is achieved with a bar positioned directly upstream of the flap side edge. The noise reduction benefit is seen to improve with increased bar width, length and proximity to the flap edge. Positioning of the landing gear model upstream of the flap side edge also leads to decreased flap side edge noise. In addition, flap cove noise levels are significantly lower than when the landing gear is positioned upstream of the flap mid-span. The impact of the local flow velocity on the noise radiating directly from the landing gear is discussed. The effects of the landing gear side-braces on flap side edge, flap cove and landing gear noise are shown.
Complex regional pain syndrome–up-to-date
Birklein, Frank; Dimova, Violeta
2017-01-01
Abstract Complex regional pain syndrome (CRPS) was described for the first time in the 19th century by Silas Weir Mitchell. After the exclusion of other causes, CRPS is characterised by a typical clinical constellation of pain, sensory, autonomic, motor, or trophic symptoms which can no longer be explained by the initial trauma. These symptoms spread distally and are not limited to innervation territories. If CRPS is not improved in the acute phase and becomes chronic, the visible symptoms change throughout because of the changing pathophysiology; the pain, however, remains. The diagnosis is primarily clinical, although in complex cases further technical examination mainly for exclusion of alternative diagnoses is warranted. In the initial phase, the pathophysiology is dominated by a posttraumatic inflammatory reaction by the activation of the innate and adaptive immune system. In particular, without adequate treatment, central nociceptive sensitization, reorganisation, and implicit learning processes develop, whereas the inflammation moderates. The main symptoms then include movement disorders, alternating skin temperature, sensory loss, hyperalgesia, and body perception disturbances. Psychological factors such as posttraumatic stress or pain-related fear may impact the course and the treatability of CRPS. The treatment should be ideally adjusted to the pathophysiology. Pharmacological treatment maybe particularly effective in acute stages and includes steroids, bisphosphonates, and dimethylsulfoxide cream. Common anti-neuropathic pain drugs can be recommended empirically. Intravenous long-term ketamine administration has shown efficacy in randomised controlled trials, but its repeated application is demanding and has side effects. Important components of the treatment include physio- and occupational therapy including behavioural therapy (eg, graded exposure in vivo and graded motor imaging). If psychosocial comorbidities exist, patients should be appropriately treated and supported. Invasive methods should only be used in specialised centres and in carefully evaluated cases. Considering these fundamentals, CRPS often remains a chronic pain disorder but the devastating cases should become rare. PMID:29392238

Nurses play an essential role in managing the care of patients with multiple myeloma, who require education and support to receive and adhere to optimal therapy. The International Myeloma Foundation created a Nurse Leadership Board comprised of oncology nurses from leading cancer centers and community practices. An assessment survey identified the need for specific recommendations for managing key side effects of novel antimyeloma agents. Myelosuppression, thromboembolic events, peripheral neuropathy, steroid toxicities, and gastrointestinal side effects were selected for the first consensus statements. The board developed recommendations for healthcare providers in any medical setting, including grading of side-effect toxicity and strategies for managing the side effects in general, with specific recommendations pertaining to the novel agents.

Comprehensive prediction of drug-protein interactions and side effects for the human proteome
Zhou, Hongyi; Gao, Mu; Skolnick, Jeffrey
2015-01-01
Identifying unexpected drug-protein interactions is crucial for drug repurposing. We develop a comprehensive proteome scale approach that predicts human protein targets and side effects of drugs. For drug-protein interaction prediction, FINDSITEcomb, whose average precision is ~30% and recall ~27%, is employed. For side effect prediction, a new method is developed with a precision of ~57% and a recall of ~24%. Our predictions show that drugs are quite promiscuous, with the average (median) number of human targets per drug of 329 (38), while a given protein interacts with 57 drugs. The result implies that drug side effects are inevitable and existing drugs may be useful for repurposing, with only ~1,000 human proteins likely causing serious side effects. A killing index derived from serious side effects has a strong correlation with FDA approved drugs being withdrawn. Therefore, it provides a pre-filter for new drug development. The methodology is free to the academic community on the DR. PRODIS (DRugome, PROteome, and DISeasome) webserver at http://cssb.biology.gatech.edu/dr.prodis/. DR. PRODIS provides protein targets of drugs, drugs for a given protein target, associated diseases and side effects of drugs, as well as an interface for the virtual target screening of new compounds.

CHECKPOINT INHIBITOR IMMUNE THERAPY: Systemic Indications and Ophthalmic Side Effects.
Dalvin, Lauren A; Shields, Carol L; Orloff, Marlana; Sato, Takami; Shields, Jerry A
2018-06-01
To review immune checkpoint inhibitor indications and ophthalmic side effects. A literature review was performed using a PubMed search for publications between 1990 and 2017. Immune checkpoint inhibitors are designed to treat system malignancies by targeting one of three ligands, leading to T-cell activation for attack against malignant cells. These ligands (and targeted drug) include cytotoxic T-lymphocyte antigen-4 (CTLA-4, ipilimumab), programmed death protein 1 (PD-1, pembrolizumab, nivolumab), and programmed death ligand-1 (PD-L1, atezolizumab, avelumab, durvalumab). These medications upregulate the immune system and cause autoimmune-like side effects. Ophthalmic side effects most frequently manifest as uveitis (1%) and dry eye (1-24%). Other side effects include myasthenia gravis (n = 19 reports), inflammatory orbitopathy (n = 11), keratitis (n = 3), cranial nerve palsy (n = 3), optic neuropathy (n = 2), serous retinal detachment (n = 2), extraocular muscle myopathy (n = 1), atypical chorioretinal lesions (n = 1), immune retinopathy (n = 1), and neuroretinitis (n = 1). Most inflammatory side effects are managed with topical or periocular corticosteroids, but advanced cases require systemic corticosteroids and cessation of checkpoint inhibitor therapy. Checkpoint inhibitors enhance the immune system by releasing inhibition on T cells, with risk of autoimmune-like side effects. Ophthalmologists should include immune-related adverse events in their differential when examining cancer patients with new ocular symptoms.
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.

The impact of prolonged disorders of consciousness on the occupational life of family members.
Elliott, Karen; McVicar, Andrew
2016-10-27
The impact of vegetative state (VS) and minimally conscious states (MCSs) on an individual is devastating. VS and MCSs may be transitional towards recovery, but may become permanent. Although devastating for the individual the nature of these conditions also has a profound effect on the family. This study examined the impact on the family member and the changes in the individuals' occupation. Six participants (spouses, partners or parents) were recruited to the study. Mixed methods were adopted to meet the requirements of the research and participants. Data were collected at 6 and 12 months post-injury, using time diaries, a questionnaire and semi-structured interviews. At 6 months post-injury the greatest amount of carers' time was allocated to occupations involving the person in a Disorder of Consciousness and less time to social and leisure activities. Participants had difficulty viewing the future, lacked the desire or capacity to engage in previously enjoyed activities. At 12 months those impacts were still evident although changing. The transition to balanced occupational activity is slow, requiring a number of catalysts to change. A conceptual framework for a return to balance is provided, and guidance on advice from family members to families in a similar situation is given.

To identify predictors of: uptake of the childhood influenza vaccine in the 2015-2016 influenza season, parental perceptions of side-effects from the influenza vaccine and intention to vaccinate one's child for influenza in the 2016-2017 influenza season. Cross-sectional online survey. Data were collected in England shortly after the end of the 2015-2016 immunization campaign. 1001 parents or guardians of children aged between two and seven. Self-reported uptake of the childhood influenza vaccine in the 2015-2016 influenza season, perception of side-effects from the influenza vaccine and intention to vaccinate one's child in the 2016-2017 influenza season. Self-reported uptake of the childhood influenza vaccine was 52.8%. Factors strongly positively associated with uptake included the child having previously been vaccinated against influenza, perceiving the vaccine to be effective and perceiving the child to be susceptible to flu. Factors strongly negatively associated with uptake included perceiving the vaccine to be unsafe, to cause short-term side-effects or long-term health problems and believing that yearly vaccination may overload the immune system. Predictors of intended vaccine uptake in 2016-2017 were similar. Participants who perceived side-effects after the 2015-2016 vaccination reported being less likely to vaccinate their child next year. Side-effects were more likely to be reported in first-born children, by participants who knew another child who had side-effects, those who thought that the vaccine would interact with medication that the child was currently taking, and those who believed the vaccine causes short-term side-effects. Perceptions about the childhood influenza vaccine show strong associations with uptake, intended uptake and perception of side-effects. Attempts to improve uptake rates from their current low levels must address these perceptions. Copyright © 2017 The Author(s). Published by Elsevier Ltd.. All rights reserved.
Persuading drivers to refrain from speeding: Effects of message sidedness and regulatory fit.
Pierro, Antonio; Giacomantonio, Mauro; Pica, Gennaro; Giannini, Anna Maria; Kruglanski, Arie W; Higgins, E Tory
2013-01-01
Building on regulatory fit theory (Higgins, 2000, 2005), we tested whether two-sided ads were more effective than one-sided ads in changing intentions toward driving behavior when message recipients were high in assessment orientation rather than locomotion orientation. In one study either a locomotion or an assessment orientation were situationally induced (Study 1) and in another study these different orientations were chronic predispositions (Study 2). As predicted, both studies found that for participants high in assessment, two-sided ads were more effective than one-sided ads, as reflected in stronger engagement with the persuasive message and stronger intentions to reduce driving speed. In contrast, for participants high in locomotion, one-sided ads were more effective than two-sided ads. There was also evidence that the fit effect on intentions to comply was mediated by strength of engagement with the message. Implications for persuasion concerning driving behaviors are discussed.

To investigate the frequency and severity of side effects of methylphenidate among childhood survivors of acute lymphoblastic leukemia and brain tumors and identify predictors of higher adverse effect levels. Childhood cancer survivors (N = 103) identified as having attention and learning problems completed a randomized, double-blind, 3-week, home-crossover trial of placebo, low-dose methylphenidate (0.3 mg/kg; 10 mg twice daily maximum) and moderate-dose methylphenidate (0.6 mg/kg; 20 mg twice daily maximum). Caregivers completed the Barkley Side Effects Rating Scale (SERS) at baseline and each week during the medication trial. Siblings of cancer survivors (N = 49) were recruited as a healthy comparison group. There was a significantly higher number and severity of symptoms endorsed on the SERS when patients were taking moderate dose compared with placebo or low dose, but not low dose compared with placebo. The number of side effects endorsed on the SERS was significantly lower during all 3 home-crossover weeks (placebo, low dose, moderate dose) when compared with baseline symptom scores. The severity of side effects was also significantly lower, compared with baseline screening, during placebo and low-dose weeks but not moderate-dose weeks. Both the number and severity of symptoms endorsed at baseline were significantly higher for patients compared with siblings. Female gender and lower IQ were associated with higher adverse effect levels. Methylphenidate is generally well tolerated by childhood cancer survivors. There is a subgroup at increased risk for side effects that may need to be closely monitored or prescribed a lower medication dose. The seemingly paradoxical findings of increased "side effects" at baseline must be considered when monitoring side effects and designing clinical trials.
Sarcopenia: pharmacology of today and tomorrow.
Brotto, Marco; Abreu, Eduardo L
2012-12-01
Sarcopenia remains largely undiagnosed and undertreated because of the lack of a universally accepted definition, effective ways to measure it, and identification of the outcomes that should guide treatment efficacy. An ever-growing number of clinicians and researchers along with funding and regulatory agencies have gradually recognized that sarcopenia is a human condition that requires both prevention and treatment. In this article, we review sarcopenia and its common and less known pharmacological treatments, attempt to define sarcopenia in its broader context, and present some new ideas for potential future treatment for this devastating condition.
Stigma of Mental Illness-1: Clinical reflections
Shrivastava, Amresh; Johnston, Megan; Bureau, Yves
2012-01-01
Although the quality and effectiveness of mental health treatments and services have improved greatly over the past 50 years, therapeutic revolutions in psychiatry have not yet been able to reduce stigma. Stigma is a risk factor leading to negative mental health outcomes. It is responsible for treatment seeking delays and reduces the likelihood that a mentally ill patient will receive adequate care. It is evident that delay due to stigma can have devastating consequences. This review will discuss the causes and consequences of stigma related to mental illness. PMID:22654383

Host Factors in Ebola Infection.
Rasmussen, Angela L
2016-08-31
Ebola virus (EBOV) emerged in West Africa in 2014 to devastating effect, and demonstrated that infection can cause a broad range of severe disease manifestations. As the virus itself was genetically similar to other Zaire ebolaviruses, the spectrum of pathology likely resulted from variable responses to infection in a large and genetically diverse population. This review comprehensively summarizes current knowledge of the host response to EBOV infection, including pathways hijacked by the virus to facilitate replication, host processes that contribute directly to pathogenesis, and host-pathogen interactions involved in subverting or antagonizing host antiviral immunity.
Switching effect of the side chain on quantum walks on triple graphs

Du, Yi-Mu; Lu, Li-Hua; Li, You-Quan
2015-07-01
We consider a continuous-time quantum walk on a triple graph and investigate the influence of the side chain on propagation in the main chain. Calculating the interchange of the probabilities between the two parts of the main chain, we find that a switching effect appears if there is an odd number of points in the side chain when concrete conditions between the length of the main chain and the position of the side chain are satisfied. However, such an effect does not occur if there is an even number of points in the side chain. We also suggest two proposals for experiments to demonstrate this effect, which may be employed to design a new type of switching device.

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.
Emerging insights into barriers to effective brain tumor therapeutics.
Woodworth, Graeme F; Dunn, Gavin P; Nance, Elizabeth A; Hanes, Justin; Brem, Henry
2014-01-01
There is great promise that ongoing advances in the delivery of therapeutics to the central nervous system (CNS) combined with rapidly expanding knowledge of brain tumor patho-biology will provide new, more effective therapies. Brain tumors that form from brain cells, as opposed to those that come from other parts of the body, rarely metastasize outside of the CNS. Instead, the tumor cells invade deep into the brain itself, causing disruption in brain circuits, blood vessel and blood flow changes, and tissue swelling. Patients with the most common and deadly form, glioblastoma (GBM) rarely live more than 2 years even with the most aggressive treatments and often with devastating neurological consequences. Current treatments include maximal safe surgical removal or biopsy followed by radiation and chemotherapy to address the residual tumor mass and invading tumor cells. However, delivering effective and sustained treatments to these invading cells without damaging healthy brain tissue is a major challenge and focus of the emerging fields of nanomedicine and viral and cell-based therapies. New treatment strategies, particularly those directed against the invasive component of this devastating CNS disease, are sorely needed. In this review, we (1) discuss the history and evolution of treatments for GBM, (2) define and explore three critical barriers to improving therapeutic delivery to invasive brain tumors, specifically, the neuro-vascular unit as it relates to the blood brain barrier, the extra-cellular space in regard to the brain penetration barrier, and the tumor genetic heterogeneity and instability in association with the treatment efficacy barrier, and (3) identify promising new therapeutic delivery approaches that have the potential to address these barriers and create sustained, meaningful efficacy against GBM.

[Side Effects of Occupational Group Therapy].
Flöge, B; Fay, D; Jöbges, M; Linden, M; Muschalla, B
2016-12-01
Background: Occupational therapy is an important co-therapy in psychiatric therapy. It is a common belief that no risks are associated with occupational therapy. Negative effects caused by group therapy, especially occupational therapy, have not been in the focus of research yet. In this study we want to illustrate possible types and intensities of group side effects through occupational therapy. Patients and Methods: Patients of an inpatient rehabilitation facility filled out the Adverse Treatment Reaction Group Checklist. The checklist contains 47 items divided in six dimensions: group size, content, group participants, group outcome and global. The self-rating used a 5-point likert scale (0 = not at all; 4 = very much, extremely stressful) and gives information about types and intensities of the side effects. Results: 88.9 % of 45 patients reported negative effects of occupational group therapy. 28.9 % of the patients rated the side effect as at least severe. Discussion: Occupational therapy is associated with side effects as every other group therapy. Possible side effects caused by group therapy should be considered while planning and implementing occupational therapy. © Georg Thieme Verlag KG Stuttgart · New York.

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.
The differences in the assessments of side effects at an oncology outpatient clinic.
Bayraktar-Ekincioglu, A; Kucuk, E
2018-04-01
Background There is a growing interest in the use of targeted and immunotherapies in oncology. However, the assessment of side effects can be different due to interpretation of patients' health status by healthcare professionals in oncology outpatient clinics. Objective To demonstrate the differences in the assessments of side effects conducted independently by a clinical pharmacist and nurses in patients who receive targeted therapies at an oncology outpatient clinic. Setting The study was conducted at the University Oncology Hospital in an outpatient clinic from October 2015 to March 2016. Method Patients receiving ipilimumab, nivolumab, pembrolizumab, bevacizumab, panitumumab or cetuximab during study period were included. The assessment of side effects was conducted by a pharmacist and nurse independently using the NCI-CTCAE version-2. Main outcome measure To compare the severity assessments of side effects between a clinical pharmacist and nurses in an outpatient clinic. Results During the study, 204 visits for 43 patients with a total of 5508 side effect assessments were recorded where 1137 (20.64%) assessments were graded differently. Out of 1137 assessments, 473 of them were graded higher by a clinical pharmacist whereas 664 were graded higher by nurses. Statistically significant differences were detected in the assessment of vomiting, taste changes, sense changes, alopecia, fatigue, mood changes, anxiety, hearing impairment, and allergic reactions. Conclusion An assessment of side effects by healthcare providers in patients with cancer may be challenging due to an increased workload in clinics and undistinguishable symptoms of side effects and cancer itself. Therefore, a new care model which increases an interprofessional communication may improve pharmaceutical care in oncology outpatient clinics.

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.
Crew Earth Observations (CEO) by Expedition Five Crew

ISS005-E-18511 (25 October 2002) --- Mount Saint Helens, Washington, is featured in this image photographed by an Expedition 5 crewmember on the International Space Station (ISS). On May 18, 1980, Mount Saint Helens volcano erupted. A series of earthquakes preceded the eruption, triggering a collapse of the north side of the mountain into a massive landslide. This avalanche coincided with a huge explosion that destroyed over 270 square miles of forest in a few seconds, and sent a billowing cloud of ash and smoke 80,000 feet into the atmosphere. The crewmembers on the Station captured this detailed image of the volcanos summit caldera. In the center of the crater sits a lava dome that is 876 feet above the crater floor and is about 3,500 feet in diameter. The upper slopes of the 1980 blast zone begin at the gray colored region that extends north (upper left) from the summit of the volcano. The deeply incised valley to the left (west) is the uppermost reach of the South Fork of the Toutle River. Devastating mudslides buried the original Toutle River Valley to an average depth of 150 feet, but in places up to 600 feet. The dark green area south of the blast zone is the thickly forested region of the Gifford Pinchot National Forest.

Stroke due to hypoperfusion or emboli is a devastating adverse event of cardiac surgery, but early detection and treatment could protect patients from an unfavorable postoperative course. Hypoperfusion and emboli can be detected with transcranial Doppler of the middle cerebral artery (MCA). The measured blood flow velocity correlates with cerebral oxygenation determined clinically by near-infrared spectroscopy (NIRS) of the frontal cortex. We tested the potential advantage of a spatially extended NIRS in detecting critical events in three cardiac surgery patients with a whole-head fiber holder of the FOIRE-3000 continuous-wave NIRS system. Principle components analysis was performed to differentiate between global and localized hypoperfusion or ischemic territories of the middle and anterior cerebral arteries. In one patient, we detected a critical hypoperfusion of the right MCA, which was not apparent in the frontal channels but was accompanied by intra- and postoperative neurological correlates of ischemia. We conclude that spatially extended NIRS of temporal and parietal vascular territories could improve the detection of critically low cerebral perfusion. Even in severe hemispheric stroke, NIRS of the frontal lobe may remain normal because the anterior cerebral artery can be supplied by the contralateral side directly or via the anterior communicating artery.

Partially folded protein species transiently exist during folding of most proteins. Often these species are molten globules, which may be on- or off-pathway to native protein. Molten globules have a substantial amount of secondary structure but lack virtually all the tertiary side-chain packing characteristic of natively folded proteins. These ensembles of interconverting conformers are prone to aggregation and potentially play a role in numerous devastating pathologies, and thus attract considerable attention. The molten globule that is observed during folding of apoflavodoxin from Azotobacter vinelandii is off-pathway, as it has to unfold before native protein can be formed. Here we report that this species can be trapped under nativelike conditions by substituting amino acid residue F44 by Y44, allowing spectroscopic characterization of its conformation. Whereas native apoflavodoxin contains a parallel beta-sheet surrounded by alpha-helices (i.e., the flavodoxin-like or alpha-beta parallel topology), it is shown that the molten globule has a totally different topology: it is helical and contains no beta-sheet. The presence of this remarkably nonnative species shows that single polypeptide sequences can code for distinct folds that swap upon changing conditions. Topological switching between unrelated protein structures is likely a general phenomenon in the protein structure universe.

Computer enhancing of side scanning sonar plots revealed images of massive art, apparent ruins of cities, and subsea temples. Some images are about four to twenty kilometers in length. Present water depths imply that many of the finds must have been created over ten thousand years ago. Also, large carvings of giant sloths, Ice Age elk, mammoths, mastodons, and other cold climate creatures concurrently indicate great age. In offshore areas of North America, some human faces have beards and what appear to be Caucasian characteristics that clearly contrast with the native tribal images. A few images have possible physical appearances associated with Polynesians. Contacts and at least limited migrations must have occurred much further in the ancient past than previously believed. Greatly rising sea levels and radical changes away from late Ice Age climates had to be devastating to very ancient civilizations. Many images indicate that these cultures were capable of construction and massive art at or near the technological level of the Old Kingdom in Egypt. Paleo astronomy is obvious in some plots. Major concerns are how to further evaluate, catalog, protect, and conserve the creations of those cultures.

Shoaib, Maria; Kraus, Jacqueline J; Khan, Muhammad T
2018-01-15
Herpes simplex virus encephalitis (HSVE) is a medical emergency associated with high mortality and morbidity. Definitive diagnosis is established by history, clinical examination, neuroimaging studies, supportive electroencephalogram (EEG) findings, and cerebrospinal fluid (CSF) analysis. We report a case of HSVE presenting as a stroke mimic in a 76-year-old female with a history of atrial fibrillation on warfarin. She was admitted to our medical intensive care unit with intermittent fever, lethargy, and new onset left-sided hemiparesis. A computed tomography (CT) of the head showed a right middle cerebral artery (MCA) acute ischemic stroke with midline shift and a dense right MCA sign. Brain magnetic resonance imaging (MRI) showed evidence of acute stroke with consideration of herpes encephalitis. CSF analysis was positive for herpes simplex virus (HSV) type one. She recovered with high-dose intravenous acyclovir therapy. Our patient was a diagnostic dilemma, initially being diagnosed with an acute ischemic stroke and yet found to have HSVE, which mimicked an acute ischemic stroke. Delay in treatment may result in devastating clinical outcomes that may include severe cognitive, focal neurological deficits, persistent seizures, and even death. This case highlights the importance of a multidisciplinary approach and the need for increased awareness of an atypical presentation of HSVE among emergency physicians, neurologist, intensivists, and radiologists.

In a prospective study lumbar iohexol myelography was performed in 107 consecutive patients, randomised for lumbar puncture with a Quincke or Whitacre spinal needle. All patients answered a questionnaire about possible side effects. Data from 100 patients (58 men, 42 women) were evaluated. In the Quincke group (n = 53), 23 (43%) reported no side effects. In the 30 patients who reported various side effects, post-dural puncture headache (PDPH) occurred in 22 (42%), of whom 9 had mild, 6 moderate and 7 (13%) severe cephalalgia, 18 (34%) reported increased low back pain/sciatica, 5 nausea and 7 dizziness. In the Whitacre group (n = 47), 33 (70%) had no side effects. PDPH was reported by 9 patients (19%), of whom 2 had mild, 6 moderate and only 1 (2%) severe cephalalgia, 4 (9%) reported increased low back pain/sciatica, 5 nausea and 4 dizziness. The conclusion drawn from this study is that lumbar myelography performed with the Whitacre spinal needle reduces postspinal side effects.

Background Seizure control doesn't represent the only challenging goal in patients with brain tumor-related epilepsy. Side effects have often taken precedence for patients' quality of life. Methods We performed an observational retrospective study on patients with brain tumor-related epilepsy: 35 who had assumed oxcarbazepine monotherapy and 35 patients who had undergone treatment with traditional antiepileptic drugs. Primary variable of efficacy was the mean seizure frequency per month and safety variables were the drop-out for side effects and total incidence of side effects. We applied the Propensity Score technique to minimize selection bias. Results Our results showed a similar efficacy of oxcarbazepine and traditional antiepileptic drugs over time, but the difference in safety and tolerability between the two groups was significant: traditional AEDs caused more side effects, both serious and non serious. Conclusion This study highlights the importance of taking into consideration not only seizure control but also the appearance of side effects when choosing antiepileptic drugs in this patients population.

Acute levodopa challenge may be performed to predict levodopa chronic responsiveness. The aim of the study was to investigate frequency of side effects during the acute levodopa challenge in PD and atypical parkinsonisms. We enrolled 34 de novo PD patients and 29 patients affected by atypical parkinsonisms (Multiple System Atrophy, MSA, n = 10; Progressive Supranuclear Palsy, PSP, n = 12 and Corticobasal Degeneration, CBD, n = 7) who underwent an acute levodopa challenge. Side effects occurring during test were recorded. Side effects were more frequent among atypical parkinsonisms as unique group when compared to PD patients (64.3% versus 23.5%; p-value 0.002) with an adjusted OR of 4.36 (95%CI 1.40-13.5). Each atypical parkinsonisms showed almost double occurrence of side effects (MSA 90%, PSP 41.7% and CBD 57%). Side effects during acute levodopa challenge may be frequent in atypical parkinsonisms. This information could be useful in order to better prepare the patient for the test. Furthermore, it could represent a useful cue in differential diagnosis with PD.

Narcolepsy is a disease in which there is diurnal excessive sleepiness with sleep attacks and a prevalence in the general population of 1/4000 individuals. Classically, it is characterized by cataplexy, sleep paralysis, hypnagogic hallucinations and fragmented sleep. The use of modafinil in the treatment of narcolepsy is the first option of treatment for diurnal excessive sleepiness. Although considered a safe drug for use in patients with narcolepsy, being utilized for more than 20 years, modafinil possesses a series of side effects, some of them still not fully researched or described. Side effects such as headache, nausea, anxiety, insomnia, lumbago, diarrhea, dyspepsia, rhinitis and vertigo are the most frequent. However, the clinical follow-up of patients under treatment with modafinil must be intensive and the side effects ought to be noted and evaluated. The under-response to treatment or the unexpected side effects must always be directed to differential diagnostics. The objective of this article is to describe an unexpected side effect of the use of modafinil in a patient with incorrect diagnosis of narcolepsy. PMID:26483900

The Liverpool University Neuroleptic Side-Effect Rating Scale (LUNSERS) was examined for its usefulness as a subjective measure of drug-induced parkinsonism and akathisia. Eighty-three subjects were assessed using the LUNSERS, the Simpson-Angus Scale (SAS) and the Barnes Akathisia Rating Scale (BARS), before and after a 6-week treatment with olanzapine. Significant correlations were found between the changes in scores of parkinsonism items of LUNSERS and SAS. The changes in scores of akathisia item (restlessness), extrapyramidal side effects (EPS) subscale and psychic side-effects subscale of LUNSERS were significantly correlated with those of the BARS. 'Shakiness', one item of the EPS subscale of LUNSERS, correctly classified between parkinsonism and non-parkinsonism groups with 81.0% accuracy. A combination of four items included in EPS and psychic side-effect subscales of LUNSERS identified akathisia and non-akathisia groups with 76.2% accuracy. These results suggest that the EPS and psychic side-effect subscales of LUNSERS may be useful in screening for drug-induced parkinsonism and akathisia. Copyright (c) 2004 John Wiley & Sons, Ltd.

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 therapeutical effectiveness of gestrinone in endometriosis treatment, as well as its long term side effects, were evaluated. Prospective, clinical trial. At "Dr. Alejandro Castanedo Kimball" Hospital (PEMEX). Salamanca, Guanajuato. México. Thirty women with laparoscopically confirmed endometriosis, were studied. Subjects received 2.5 mg. of gestrinone two times per week for 6 months. Laparoscopy was performed before treatment, and clinical response was determined by second laparoscopy after 6 months. The pregnancy rate, frequency of side effects and recurrence of symptoms were determined. Median total endometriosis scores and symptoms decreased significantly after treatment. Four pregnancies were observed after treatment. The principal side effects were: ponderal increase, changes in the voice and hirsutism. However, the side effects disappeared after one year of clinical survey. The results indicate that gestrinone is effective in the treatment of pelvic endometriosis. In despite of a clear benefic effect on stage of the disease and symptoms; the use of gestrinone should weigh the risk-benefit (cost versus metabolic side effects) of treatment.

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
Integrative relational machine-learning for understanding drug side-effect profiles
2013-01-01
Background Drug side effects represent a common reason for stopping drug development during clinical trials. Improving our ability to understand drug side effects is necessary to reduce attrition rates during drug development as well as the risk of discovering novel side effects in available drugs. Today, most investigations deal with isolated side effects and overlook possible redundancy and their frequent co-occurrence. Results In this work, drug annotations are collected from SIDER and DrugBank databases. Terms describing individual side effects reported in SIDER are clustered with a semantic similarity measure into term clusters (TCs). Maximal frequent itemsets are extracted from the resulting drug x TC binary table, leading to the identification of what we call side-effect profiles (SEPs). A SEP is defined as the longest combination of TCs which are shared by a significant number of drugs. Frequent SEPs are explored on the basis of integrated drug and target descriptors using two machine learning methods: decision-trees and inductive-logic programming. Although both methods yield explicit models, inductive-logic programming method performs relational learning and is able to exploit not only drug properties but also background knowledge. Learning efficiency is evaluated by cross-validation and direct testing with new molecules. Comparison of the two machine-learning methods shows that the inductive-logic-programming method displays a greater sensitivity than decision trees and successfully exploit background knowledge such as functional annotations and pathways of drug targets, thereby producing rich and expressive rules. All models and theories are available on a dedicated web site. Conclusions Side effect profiles covering significant number of drugs have been extracted from a drug ×side-effect association table. Integration of background knowledge concerning both chemical and biological spaces has been combined with a relational learning method for discovering rules which explicitly characterize drug-SEP associations. These rules are successfully used for predicting SEPs associated with new drugs. PMID:23802887

To identify the side effects most important to glucocorticoid (GC) users through a survey of a UK online health community (Healthunlocked.com). Online cross-sectional survey. Participants were recruited through Healthunlocked.com, an online social network for health. Adults who were currently taking GCs, or had taken GCs in the past month. Responders scored the importance of listed side effects from 1 to 10, with 10 being of high importance to them. For each side effect, histograms were plotted, and the median rating and IQR were determined. Side effects were ranked by median ranking (largest to smallest) and then IQR (smallest to largest). The scores were categorised as low (scores 1-3), medium (scores 4-7) and high (scores 8-10) importance. 604 responders completed the survey. Histograms of side effect scores showed a skew towards high importance for weight gain, a U-shaped distribution for cardiovascular disease (CVD), diabetes, eye disease and infections, and a skew towards low importance for acne. When ranked, the side effect of most importance to responders was weight gain (median score=9, IQR 6-10) followed by insomnia and moon face with equal median score (8) and IQR (5-10). Three serious side effects, CVD, diabetes and infections, were ranked of lower importance overall but had wide ranging scores (median score=8, IQR 1-10). The three most highly rated side effects were not clinically serious but remained important to patients, perhaps reflecting their impact on quality of life and high prevalence. This should be taken into consideration when discussing treatment options and planning future GC safety studies. Published by the BMJ Publishing Group Limited.

Patient expectancies are hypothesized to contribute to the efficacy and side effects of psychiatric treatments, but little research has investigated this hypothesis in the context of psychopharmacological therapies for anxiety. We prospectively investigated whether expectancies predicted efficacy and adverse events in oral therapy for Generalized Anxiety Disorder (GAD), controlling for confounding patient characteristics correlating with outcomes. Expectancies regarding treatment efficacy and side effects were assessed at baseline of an eight week open-label phase of a trial of chamomile for Generalized Anxiety Disorder (GAD). The primary outcome was patient-reported GAD-7 scores, with clinical response and treatment-emergent side-effects as secondary outcomes. Expectancies were used to predict symptomatic and side-effect outcomes. Very few baseline patient characteristics predicted either type of expectancy. Controlling for a patient's predicted recovery based on their baseline characteristics, higher efficacy expectancies at baseline predicted greater change on the GAD-7 (adjusted β = -0.19, p = 0.011). Efficacy expectancies also predicted a higher likelihood of attaining clinical response (adjusted odds ratio = 1.69, p = 0.002). Patients with higher side effect expectancies reported more side effects (adjusted log expected count = 0.26, p = 0.038). Efficacy expectancies were unrelated to side effect reports (log expected count = -0.05, p = 0.680), and side effect expectancies were unrelated to treatment efficacy (β = 0.08, p = 0.306). Patients entering chamomile treatment for GAD with more favorable self-generated expectancies for the treatment experience greater improvement and fewer adverse events. Aligning patient expectancies with treatment selections may optimize outcomes. Trial Number NCT01072344 at ClinicalTrials.gov. Copyright © 2016 Elsevier Ltd. All rights reserved.

Cytochrome P450 enzymes are important in the metabolism of antidepressants. The highly polymorphic nature of these enzymes has been linked to variability in antidepressant metabolism rates, leading to hope regarding the use of P450 genotyping to guide treatment. However, evidence that P450 genotypic differences underlie the variation in treatment outcomes is inconclusive. We explored the links between both P450 genotype and serum concentrations of antidepressant with antidepressant side effects, using data from the Genome-Based Therapeutic Drugs for Depression Project (GENDEP), which is a large (n = 868), pharmacogenetic study of depressed individuals treated with escitalopram or nortriptyline. Patients were genotyped for the enzymes CYP2C19 and CYP2D6, and serum concentrations of both antidepressant and primary metabolite were measured after 8 weeks of treatment. Side effects were assessed weekly. We investigated associations between P450 genotypes, serum concentrations of antidepressants and side effects, as well as the relationship between P450 genotype and study discontinuation. P450 genotype did not predict total side effect burden (nortriptyline: n = 251, p = 0.5638, β = -0.133, standard error (SE) = 0.229; escitalopram: n = 340, p = 0.9627, β = -0.004, SE = 0.085), study discontinuation (nortriptyline n = 284, hazard ratio (HR) = 1.300, p = 0.174; escitalopram n = 376, HR = 0.870, p = 0.118) or specific side effects. Serum concentrations of antidepressant were only related to a minority of the specific side effects measured: dry mouth, dizziness and diarrhoea. In this sample where antidepressant dosage is titrated using clinical judgement, P450 genotypes do not explain differences between patients in side effects with antidepressants. Serum drug concentrations appear to only explain variability in the occurrence of a minority of specific side effects.

To examine baseline psychological functioning and antiepileptic drug (AED) behavioral side effects in new onset epilepsy and determine, by age, whether baseline psychological functioning predicts AED behavioral side effects 1 month following AED initiation. A retrospective chart review was conducted between July 2011 and December 2014 that included youths with new onset epilepsy. As part of routine interdisciplinary care, caregivers completed the Behavior Assessment System for Children, 2nd Edition: Parent Rating Scale to report on baseline psychological functioning at the diagnostic visit and the Pediatric Epilepsy Side Effects Questionnaire to identify AED behavioral side effects at the 1-month follow-up clinic visit following AED initiation. Children (age = 2-11 years) and adolescents (age = 12-18 years) were examined separately. A total of 380 youths with new onset epilepsy (M age = 8.9 ± 4.3 years; 83.4% Caucasian; 34.8% focal epilepsy, 41.1% generalized epilepsy, 23.7% unclassified epilepsy) were included. Seventy percent of youths had at-risk or clinically elevated baseline psychological symptoms. Children had significantly greater AED behavioral side effects (M = 25.08 ± 26.36) compared to adolescents (M = 12.36 ± 17.73), regardless of AED. Valproic acid demonstrated significantly greater behavioral side effects compared to all other AEDs, with the exception of levetiracetam. Higher hyperactivity/impulsivity at baseline significantly predicted higher AED behavioral side effects 1 month after AED initiation in both age groups. Younger children seem to be more prone to experience behavioral side effects, and these are likely to be higher if youths with epilepsy have baseline hyperactivity/impulsivity. Baseline psychological screening, specifically hyperactivity, can be used as a precision medicine tool for AED selection. Wiley Periodicals, Inc. © 2017 International League Against Epilepsy.
Lymphadenitis as a Rare Side Effect of H1N1 Vaccine in a Child

We present a 5-year-old boy who had the complaint of swelling and pain on the right vaccine shot and right axillary areas. The right axillary area was diagnosed as reactive lymphadenitis, which we believe is a rare local side effect of the swine flu vaccine. The key message to take away from this case is that the patient had lymphadenitis as a local side effect of the swine flu vaccine. Lymphadenitis should be reported as a possible local side effect of the swine flu vaccine. PMID:21209734
The geomorphic impact of catastrophic glacier ice loss in mountain regions
NASA Astrophysics Data System (ADS)
Evans, S. G.
2006-12-01
Perhaps the most dramatic manifestation of global warming is catastrophic glacier ice loss in mountain regions. The geomorphic impact of this process was first outlined by Evans and Clague in 1994 and includes mountain slope instability, glacier avalanching, the formation and failure of moraine dammed lakes, and the formation and failure of ice dammed lakes. The present paper is an update of the 1994 publication and has three components. First, a global review of recent glacier-related geomorphic events is undertaken. Second, an analysis of two cases from the Coast Mountains of British Columbia - the 1975 Devastation Glacier landslide and the 1983 Nostetuko Lake outburst resulting from the failure of a moraine dam illustrates the interaction of glacier ice loss and related geomorphic events. At Devastation Glacier, approximately 13 M m3 of altered Quaternary volcanic rock and glacier ice was lost from the west flank of Pylon Peak in the Mount Meager volcanic complex. The events were initiated by a catastrophic rockslide, involving altered Quaternary pyroclastic rocks, which continued down Devastation Creek valley as a high velocity debris avalanche. The overall length of the slide path was 7 km and the vertical height of the path was 1220 m yielding a fahrboschung of 10°. Other large landslides occurred in Devastation Creek valley in 1931 and 1947. Stability analysis of the initial failure shows that the 1975 rockslide was the result of a complex history of glacial erosion, loading and unloading of the toe of the slide mass caused by the Little Ice Age advance and subsequent retreat of Devastation Glacier. The shearing resistance along the base of the rockslide mass was reduced prior to 1975 by substantial previous slope displacements related to glacial ice loss. Some of this displacement is likely to have occurred as subglacial slope deformation since ice fall and crevasse patterns suggest the presence of slide like shearing displacements below the base of adjacent glacier ice. In the Nostetuko case, the analysis of large-scale digital elevation models indicate that the outburst of 6.5 M m3 of water was initiated by a 1.5 M m3 glacier avalanche from Cumberland Glacier which initiated the breach. 1.6 M m3 of moraine was removed during the sudden breach and injected into the headwaters of the Nostetuko River.

A quantitative evaluation method of the suction effect from a suction plate on side walls is explained. It is found from wind tunnel tests that the wall interference is basically described by the summation form of wall interferences in the case of two dimensional flow and the interference of side walls.
Side to Side Supercharging Allograft
Side-to-side grafting between the PNA and regional in situ nerve trunks may be able to increase the effective critical length of the PNA. Nerve tissue...and provides an effective scaffolding system but depends on in situ Schwann cell migration to support axon regeneration. Though this process appears...loss and retraction can result in segmental gaps requiring some form of grafting. Autologous nerve grafting is associated with potential donor

As part of a large-scale international cooperative investigation into the side effects of thioacetazone-containing regimens in the treatment of tuberculosis, an evaluation has been made of the variation in the frequency of side effects between different countries and between different centres in the same country and of the likely reasons for this variation. In 3 countries patients of different racial origin were under observation in the same hospital. Over a 12-week period of treatment there was considerable variation between the countries and centres in the overall frequency of side effects and of those leading to a major departure from prescribed treatment, the variation being similar for the two thioacetazone-containing regimens and for the streptomycin plus isoniazid control regimen, though at a lower level for the latter. In Malaysia, Singapore, and Trinidad, where different racial groups were under treatment, there was no clear indication that race was an important factor in explaining the differences between countries, except for cutaneous side effects in Trinidad and possibly in Malaysia. It is concluded that the differences in the frequency of side effects to thioacetazone-containing regimens probably result from variation in the closeness of supervision of patients, in the recording and interpretation of side effects, and in environmental factors including the previous use of other medicaments or exposure to sensitizing substances.

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.

To gain insight into patients' medical decisions by exploring the content of laypeople's spontaneous mental associations with the term "side effect." An online cross-sectional survey asked 144 women aged 40-74, "What are the first three things you think of when you hear the words 'side effect?"' Data were analyzed using content analysis, chi-square, and Fisher's exact tests. 17 codes emerged and were grouped into 4 themes and a Miscellaneous category: Health Problems (70.8% of participants), Decision-Relevant Evaluations (52.8%), Negative Affect (30.6%), Practical Considerations (18.1%) and Miscellaneous (9.7%). The 4 most frequently identified codes were: Risk (36.1%), Health Problems-Specific Symptoms (35.4%), Health Problems-General Terms (32.6%), and Negative Affect-Strong (19.4%). Code and theme frequencies were generally similar across demographic groups (ps>0.05). The term "side effect" spontaneously elicited comments related to identifying health problems and expressing negative emotions. This might explain why the mere possibility of side effects triggers negative affect for people making medical decisions. Some respondents also mentioned decision-relevant evaluations and practical considerations in response to side effects. Addressing commonly-held associations and acknowledging negative affects provoked by side effects are first steps healthcare providers can take towards improving informed and shared patient decision making.

Muscle-related side-effects of statins: from mechanisms to evidence-based solutions.
Taylor, Beth A; Thompson, Paul D
2015-06-01
This article highlights the recent findings regarding statin-associated muscle side effects, including mechanisms and treatment as well as the need for more comprehensive clinical trials in statin myalgia. Statin myalgia is difficult to diagnose and treat, as major clinical trials have not routinely assessed muscle side-effects, there are few clinically relevant biomarkers and assessment tools for the symptoms, many apparent statin-related muscle symptoms may be nonspecific and related to other drugs or health conditions, and prevalence estimates vary widely. Data thus suggest that only 30-50% of patients with self-reported statin myalgia actually experience muscle pain on statins during blinded, placebo-controlled trials. In addition, evidence to date involving mechanisms underlying statin myalgia and its range of symptoms and presentations supports the hypothesis that there are multiple, interactive and potentially additive mechanisms underlying statin-associated muscle side-effects. There are likely multiple and interactive mechanisms underlying statin myalgia, and recent studies have produced equivocal data regarding prevalence of statin-associated muscle side-effects, contributing factors and effectiveness of common interventions. Therefore, more clinical trials on statin myalgia are critical to the field, as are systematic resources for quantifying, predicting and reporting statin-associated muscle side-effects.

Applying mobile base systems in cancer care especially in chemotherapy management have remarkable growing in recent decades. Because chemotherapy side effects have significant influences on patient's lives, therefore it is necessary to take ways to control them. This research has studied some experiences of using mobile phone based systems to home-based monitor of chemotherapy side effects in cancer. In this literature review study, search was conducted with keywords like cancer, chemotherapy, mobile phone, information technology, side effects and self managing, in Science Direct, Google Scholar and Pub Med databases since 2005. Today, because of the growing trend of the cancer, we need methods and innovations such as information technology to manage and control it. Mobile phone based systems are the solutions that help to provide quick access to monitor chemotherapy side effects for cancer patients at home. Investigated studies demonstrate that using of mobile phones in chemotherapy management have positive results and led to patients and clinicians satisfactions. This study shows that the mobile phone system for home-based monitoring chemotherapy side effects works well. In result, knowledge of cancer self-management and the rate of patient's effective participation in care process improved.
Inferring protein domains associated with drug side effects based on drug-target interaction network
2013-01-01
Background Most phenotypic effects of drugs are involved in the interactions between drugs and their target proteins, however, our knowledge about the molecular mechanism of the drug-target interactions is very limited. One of challenging issues in recent pharmaceutical science is to identify the underlying molecular features which govern drug-target interactions. Results In this paper, we make a systematic analysis of the correlation between drug side effects and protein domains, which we call "pharmacogenomic features," based on the drug-target interaction network. We detect drug side effects and protein domains that appear jointly in known drug-target interactions, which is made possible by using classifiers with sparse models. It is shown that the inferred pharmacogenomic features can be used for predicting potential drug-target interactions. We also discuss advantages and limitations of the pharmacogenomic features, compared with the chemogenomic features that are the associations between drug chemical substructures and protein domains. Conclusion The inferred side effect-domain association network is expected to be useful for estimating common drug side effects for different protein families and characteristic drug side effects for specific protein domains.

Nicotine replacement therapy (NRT) significantly increases the likelihood of quit success at least over the short term, yet some smokers prematurely discontinue use. NRT side effects are often cited as the primary reason for medication discontinuation. The current study examined a theoretical pathway by which two smoking-related emotional vulnerabilities (anxiety sensitivity and emotion dysregulation) were related to the number of NRT (nicotine patch) side effects reported 1 week following a scheduled quit attempt. It was hypothesized that anxiety sensitivity would have an indirect effect on NRT side effects through emotion dysregulation. A total of 179 treatment-seeking, adult daily smokers with elevated anxiety sensitivity (47.5% male; M age = 39.73 years, SD = 13.87) were enrolled in a smoking cessation trial. Covariate-adjusted analyses provided support for the hypothesized pathway, such that emotion dysregulation explained the association between anxiety sensitivity and NRT side effects (b = 0.02, SE = 0.01, 95% CI [0.002, 0.03]; completely standardized estimate = .15). The findings underscore the importance of developing cessation treatments that incorporate techniques to enhance emotion regulation, particularly among smokers higher in anxiety sensitivity, to decrease the risk of NRT side effects.
