    Full Text Available Postoperative endophthalmitis is a very devastating complication and every step should be taken to reduce its occurrence. Unattended air conditioning filter systems are often the culprits and regular maintenance of the filters is of paramount importance. Shedders of pathogenic organisms amongst the theater personnel should be identified by regular screening and should be promptly treated. In addition to the use of Povidone iodine 5% solution in the conjunctival sac few minutes prior to surgery, proper construction of wound, injectable intraocular lenses, use of prophylactic intracameral antibiotics or prophylactic subconjunctival antibiotic injection at the conclusion of cataract surgery, placing a patch after the surgery for at least 4 h and initiating topical antibiotics from the same day of surgery helps to lower the frequency of postoperative endophthalmitis. Intraoperative posterior capsule rupture and anterior vitrectomy are risk factors for acute endophthalmitis, and utmost care to prevent posterior capsular rent should be taken while performing cataract surgery. Also, in case of such complication, these patients should be closely monitored for early signs of endophthalmitis in the postoperative period. In the unfortunate event of endophthalmitis the diagnosis should be prompt and treatment must be initiated as early as possible.

    Full Text Available Background: This is a theoretical and experimental study of the thermomechanical effects of laser radiation with a wavelength of 1.06 microns on the eye tissues during a laser surgery on the secondary cataract (pupillary membrane. Its relevance is related to the rates of complications after laser surgery of the eye associated with the choice of energy and time parameters of the laser irradiation. These parameters are related to the occurrence of such factors as unstable fields of thermal stress and pressure that are difficult to take into account and indirectly lead to adverse events when removing the secondary cataract. Aim: To minimize side effects and to optimize the existing technology of laser removal of the secondary cataract. Materials and methods: Samples of a  normal lens capsule and of lens capsules with various types of opacities taken during a  cataract surgery, with various optic characteristics and thickness, were treated with an infrared laser (Nd:YAG laser, 1064 nm. We performed morphometric measurements and built up a  theoretical model of the processes in a continuous medium under the effects of impulse laser irradiation. Results: The results of numerical modelling with this newly developed theoretical model are in satisfactory agreement with the experimental data on development of deformities obtained with the autopsy materials (posterior capsule of the human lens with various optical characteristics and thickness, from thin transparent membranes to more thick opaque samples. Conclusion: This study would allow for optimization of the technology of laser treatment for secondary cataracts by changing the irradiation parameters during the procedure. 

  4. Nanotechnology for the Prevention and Treatment of Cataract.

    The purpose of this article was to review recent advances in the applications of nanotechnology in cataract treatment and prevention strategies. A literature review on the use of nanotechnology for the prevention and treatment of cataract was done. Research articles about nanotechnology-based treatments and prevention technologies for cataract were searched on Web of Science, and the most recent advances were reported. Nonsteroid anti-inflammatory drugs, natural antioxidants, biologic and chemical chaperones, and chaperones such as molecules have found great application in preventing and treating cataracts. Current scientific research on new treatment strategies, which focuses on the biochemical basis of the disease, will likely result in new anticataract agents. However, none of the drug formulations will be approved for use unless efficient delivery is promised. Nanoparticle engineering together with biomimetic strategies enable the development of next-generation, more efficient, less complex, and personalized treatments. The only currently available treatment for cataracts, surgical replacement of the opacified lens, is not an easily accessible option in developing countries. New treatment strategies based on topical drugs would enable treatment to reach massive populations facing the threat of blindness and more effectively deal with the postsurgical complications. Nanotechnology plays a key role in improving drug delivery systems with enhanced controlled release, targeted delivery, and bioavailability to overcome diffusion limitations in the eye.

    Age-related cataract is a major cause of visual impairment in the elderly. Oxidative stress has been implicated in its formation and progression. Antioxidant vitamin supplementation has been investigated in this context. To assess the effectiveness of antioxidant vitamin supplementation in preventing and slowing the progression of age-related cataract. We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (The Cochrane Library 2012, Issue 2), MEDLINE (January 1950 to March 2012), EMBASE (January 1980 to March 2012), Latin American and Caribbean Literature on Health Sciences (LILACS) (January 1982 to March 2012), Open Grey (System for Information on Grey Literature in Europe) (www.opengrey.eu/), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com), ClinicalTrials.gov (www.clinicaltrials.gov) and the WHO International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). There were no date or language restrictions in the electronic searches for trials. The electronic databases were last searched on 2 March 2012. We also checked the reference lists of included studies and ongoing trials and contacted investigators to identify eligible randomized trials. We included only randomized controlled trials in which supplementation with one or more antioxidant vitamins (beta-carotene, vitamin C and vitamin E) in any form, dosage or combination for at least one year was compared to another antioxidant vitamin or to placebo. Two authors extracted data and assessed trial quality independently. We pooled results for the primary outcomes, i.e., incidence of cataract and incidence of cataract extraction. We did not pool results of the secondary outcomes - progression of cataract and loss of visual acuity, because of differences in definitions of outcomes and data presentation. We pooled results by type of cataract when data were available. We did not perform a sensitivity analysis. Nine trials involving 117

    Full Text Available Background and objective: Post Operative endophthalmitis is rare but devastating complication in ocular surgery. The present study determined the efficacy of intracameral vancomycin after phaco-emusification cataract surgery to prevent endophthalmitis. Method: A total of 768 cases who had undergone phaco-emusification cataract surgery were included in the study. Every alternate patient received 0.5 ml injection of vancomycin (1mg in 0.1 ml in the anterior chamber after completion of phaco-emulcification and formation of anterior chamber. All the patients were examined for symptoms and signs of bacterial endophthalmitis at 24 hrs, 7 days, 15 days and subsequently at 1, 3 and 6 months following surgery. Results: No endophthalmitis case was recorded at any time period during 6 month follow up in either group. However, significantly higher number of cases in vancomycin group had cells in anterior chamber and disturbances in visual acuity at day 15 following surgery. Conclusion: Vancomycin did not have any prophylactic role in preventing endophthalmitis. Proper aseptic measures are important to prevent any infection in ocular surgery.

    antibiotics alone (risk ratio (RR) 0.33, 95% confidence interval (CI) 0.12 to 0.92 (periocular penicillin and topical chloramphenicol-sulfadimidine; 6618 participants; moderate-certainty evidence); and RR 0.20, 95% CI 0.04 to 0.91 (intracameral cefuroxime and topical levofloxacin; 8101 participants; high-certainty evidence)). One study, which compared fixed versus separate instillation of gatifloxacin and prednisolone, was not sufficiently powered to detect differences in endophthalmitis between groups (very low-certainty evidence). Another study found no evidence of a difference in endophthalmitis when comparing subconjunctival versus retrobulbar antibiotic injections (RR 0.85, 95% CI 0.55 to 1.32; 77,015 participants; moderate-certainty evidence). Two studies reported any visual acuity outcome; one study, which compared fixed versus separate instillation of gatifloxacin and prednisolone, reported only that mean visual acuity was the same for both groups at 20 days postoperation. In the other study, the difference in the proportion of eyes with final visual acuity greater than 20/40 following endophthalmitis between groups receiving intracameral cefuroxime with or without topical levofloxacin compared with no intracameral cefuroxime was uncertain (RR 0.69, 95% CI 0.22 to 2.11; 29 participants; moderate-certainty evidence). Only one study reported adverse events (1 of 129 eyes had pupillary membrane in front of the intraocular lens and 8 eyes showed posterior capsule opacity). No study reported outcomes related to quality of life or economic outcomes. Authors’ conclusions Multiple measures for preventing endophthalmitis following cataract surgery have been studied. High-certainty evidence shows that injection with cefuroxime with or without topical levofloxacin lowers the chance of endophthalmitis after surgery, and there is moderate-certainty evidence to suggest that using antibiotic eye drops in addition to antibiotic injection probably lowers the chance of

    Patients having cataract surgery have often earlier undergone a trabeculectomy for glaucoma. However, cataract surgery may be associated with failure of the previous glaucoma surgery and antimetabolites may be used with cataract surgery to prevent such failure. There is no systematic review on whether antimetabolites with cataract surgery prevent failure of a previous trabeculectomy. To assess the effects of antimetabolites with cataract surgery on functioning of a previous trabeculectomy. We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (2014, Issue 5), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE (January 1946 to June 2014), EMBASE (January 1980 to June 2014), Latin American and Caribbean Health Sciences Literature Database (LILACS) (January 1982 to June 2014), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com), ClinicalTrials.gov (www.clinicaltrials.gov) and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en).

    To compare the efficacy of a topical nonsteroidal antiinflammatory drug, topical corticosteroid, and a combination of both drugs to prevent the occurrence of cystoid macular edema (CME) after cataract surgery in nondiabetic patients. Twelve European study centers. Randomized clinical trial. Nondiabetic patients having uneventful cataract surgery were included in this study. Patients were randomized to receive topical bromfenac 0.09% twice daily for 2 weeks or dexamethasone 0.1% 4 times daily with 1 drop less per day every following week, or a combination of both. The primary outcome was the difference in central subfield mean macular thickness 6 weeks postoperatively. Secondary outcome measures included corrected distance visual acuity as well as the incidence of CME and clinically significant macular edema (CSME) within 6 weeks and 12 weeks postoperatively. This study comprised 914 patients. Six weeks postoperatively, the central subfield mean macular thickness was 288.3 μm, 296.0 μm, and 284.5 μm in the bromfenac group, dexamethasone group, and combination treatment group, respectively (overall P = .006). The incidence of clinically significant macular edema within 12 weeks postoperatively was 3.6%, 5.1%, and 1.5%, respectively (overall P = .043). Patients treated with a combination of topical bromfenac 0.09% and dexamethasone 0.1% had a lower risk for developing CSME after cataract surgery than patients treated with a single drug.

    Capsule tear-out in hypermature cataracts (Argentinean flag sign) is a common and frustrating complication during the creation of a capsulorhexis. Completing the capsulorhexis through a small side-port incision, filling the anterior chamber with a highly viscous ophthalmic viscosurgical device such as a viscoadaptive agent, and using a 23- or 25-gauge microcapsulorhexis forceps to fill the side-port incision can reliably prevent this complication.

    Abstract Background: Posterior capsular opacification (PCO) is a common long-term complication of cataract surgery. Intraocular lens design and material have been implicated in influencing the development of PCO. This study evaluated the association of hydrophobic and hydrophilic intraocular lenses on preventing PCO. Methods: Medline, Cochrane, EMBASE, and Google Scholar databases were searched until August 3, 2016, using the following search terms: cataract, posterior capsule opacification, and intraocular lens. Eligible studies included randomized controlled trials (RCTs), retrospective, and cohort studies. Results: Eleven studies were included in the study with a total of 889 eyes/patients. The overall analysis revealed that hydrophobic intraocular lenses were associated with lower Nd:YAG laser capsulotomy rates than hydrophilic lenses [odds ratio (OR) = 0.38, 95% confidence interval (95% CI) = 0.16–0.91, P = .029]. Hydrophobic intraocular lenses were also associated with lower subjective PCO score (diff. in means: −1.32, 95% CI = −2.39 to −0.25, P = .015) and estimated PCO score (diff. in means: −2.23; 95% CI, −3.80 to −0.68, P = .005) as compared with hydrophilic lenses. Objective PCO score was similar between lens types. (diff. in means: −0.075; 95% CI, −0.18 to 0.035; P = .182). Pooled analysis found that visual acuity was similar between hydrophobic and hydrophilic intraocular lenses (diff. in means: −0.016; 95% CI, −0.041 to 0.009, P = .208). Conclusion: In general, PCO scores and the rate of Nd:YAG laser capsulotomy were influenced by intraocular lens biomaterial. Lens made of hydrophobic biomaterial were overall superior in lowering the PCO score and the Nd:YAG laser capsulotomy rate, but not visual acuity. PMID:29095259

    2012-01-01

    Full Text Available Objective. Effects of Syringic acid (SA extracted from dendrobii on diabetic cataract (DC pathogenesis were explored. Methods. Both in vitro and in vivo DC lens models were established using D-gal, and proliferation of HLEC exposed to SA was determined by MMT assay. After 60-day treatment with SA, rat lens transparency was observed by anatomical microscopy using a slit lamp. SA protein targets were extracted and isolated using 2-DE and MALDI TOF/TOF. AR gene expression was investigated using qRT-PCR. Interaction sites and binding characteristics were determined by molecule-docking techniques and dynamic models. Results. Targeting AR, SA provided protection from D-gal-induced damage by consistently maintaining lens transparency and delaying lens turbidity development. Inhibition of AR gene expression by SA was confirmed by qRT-PCR. IC50 of SA for inhibition of AR activity was 213.17 μg/mL. AR-SA binding sites were Trp111, His110, Tyr48, Trp20, Trp79, Leu300, and Phe122. The main binding modes involved hydrophobic interactions and hydrogen bonding. The stoichiometric ratio of non-covalent bonding between SA and AR was 1.0 to 13.3. Conclusion. SA acts to prevent DC in rat lenses by inhibiting AR activity and gene expression, which has potential to be developed into a novel drug for therapeutic management of DC.

It is estimated that a high percentage of non-cardioembolic ischemic stroke can be prevented by a suitable modification of lifestyle (diet and exercise), reducing blood pressure (BP) with antihypertensive medication, platelet aggregation inhibitors, statins and high intake reducing consumption of. Unfortunately the degree of control of the different risk factors in secondary prevention of stroke is low. The clinical practice guidelines show clear recommendations with corresponding levels of evidence, but only if implemented in a general way they will get a better primary and secondary stroke prevention.

    Breast cancer is the most common cancer among women and is the second cancer frequently occurring worldwide of newly-diagnosed cancers. There is much evidence showing the influence of life style and environmental factors on the development of mammary gland cancer (high-fat diet, alcohol consumption, lack of physical exercise), the elimination of which (primary prevention) may contribute to a decrease in morbidity and mortality. Secondary prevention, comprising diagnostic tests (e.g. mammography, ultrasonography, magnetic resonance imaging, breast self-examination, as well as modern and more precise imaging methods) help the early detection of tumours or lesions predisposing to tumours. The aim of this study paper is to review current knowledge and reports regarding primary and secondary prevention of breast cancer. It is estimated that nearly 70% of malign tumours are caused by environmental factors, whereas in breast cancer this percentage reaches 90-95%. There are national programmes established in many countries to fight cancer, where both types of prevention are stressed as serving to decrease morbidity and mortality due to cancers. Cancer prevention is currently playing a key role in the fight against the disease. Behaviour modification, as well as greater awareness among women regarding breast cancer, may significantly contribute towards reducing the incidence of this cancer. Another important aspect is the number of women undergoing diagnostic tests, which still remains at an unsatisfactory level.

    Cataract is a significant cause of visual disability with relatively high incidence. It has been proposed that such high incidence is related to oxidative stress induced by continued intraocular penetration of light and consequent photochemical generation of reactive oxygen species, such as superoxide and singlet oxygen and their derivatization to other oxidants, such as hydrogen peroxide and hydroxyl radical. The latter two can also interact to generate singlet oxygen by Haber-Weiss reaction. It has been proposed that in addition to the endogenous enzymatic antioxidant enzymes, the process can be inhibited by many nutritional and metabolic oxyradical scavengers, such as ascorbate, vitamin E, pyruvate, and xanthine alkaloids, such as caffeine. Initial verification of the hypothesis has been done primarily by rat and mouse lens organ culture studies under ambient as well as ultraviolet (UV) light irradiation and determining the effect of such irradiation on its physiology in terms of its efficiency of active membrane transport activity and the levels of certain metabolites such as glutathione and adenosine triphosphate as well as in terms of apoptotic cell death. In vivo studies on the possible prevention of oxidative stress and cataract formation have been conducted by administering pyruvate and caffeine orally in drinking water and by their topical application using diabetic and galactosemic animal models. Photosensitized damage to lens caused by exposure to visible light and UVA has been found to be significantly prevented by ascorbate and pyruvate. Caffeine has been found be effective against UVA and UVB. Oral or topical application of pyruvate has been found to inhibit the formation of cataracts induced by diabetes and galactosemia. Caffeine has also been found to inhibit cataract induced by sodium selenite and high levels of galactose. Studies with diabetes are in progress. Various in vitro and in vivo studies summarized in this review strongly support the

    Worldwide, more than 7 million people experience acute myocardial infarction (AMI) every year (1), and although substantial reduction in mortality has been obtained in recent decades, one-year mortality rates are still in the range of 10%. Among patients who survive AMI, 20% suffer a second cardiovascular event in the first year and approximately 50% of major coronary events occur in those with a previous hospital discharge diagnosis of AMI (2). Despite the evidence that lifestyle changes and risk factors management strongly improve long-term prognosis, preventive care post-AMI remains sub-optimal. Cross-sectional data from the serially conducted EUROASPIRE surveys in patients with established ischemic heart disease (IHD) and people at high cardiovascular risk have demonstrated a high prevalence of unhealthy lifestyle, modifiable risk factors and inadequate use of drug therapies to achieve blood pressure and lipid goals (3). Secondary prevention programmes, defined as the level of preventive care focusing on early risk stratification, are highly recommended in all IHD patients, to restore quality of life, maintain or improve functional capacity and prevent recurrence.

    Full Text Available Cataract is a visual impairment caused due to opacification or optical dysfunction of crystallin lens affecting more than 17 million people around the world. Even though the incidences of cataract are increasing day by day among the elderly persons but, still except surgery no other ways of treatment have been successfully developed so far. Thus, the aim of writing the present review is to provide an insight over the pathophysiological and etiological aspects of cataract along with discussing the remedies available for the disorder. The review also describes different experimental models with their relevant mechanism and significance such as galactose-induced, naphthalene-induced and selenite-induced cataract models which are mainly used for evaluating the anticataract activity of a particular drug (mainly of natural origin. The review includes list of plants and their phytoconstituents which have been so far evaluated pharmacologicaly for the treatment of cataract. From the survey, it was confirmed that the antioxidant property of plants phytoconstituents are basically responsible for their effective anticataract activity. Thus, the valuable information provided in the present review will help researches in developing an alternative method rather than surgery for the treatment of cataract which will minimize the rate of blindness due to cataract thus, benefiting and extending protective aspects of eyes, an integral part of human body.

    Full Text Available Purpose. As a secondary analysis, we reassess the association of initial congenital cataract surgery times, compliance to amblyopia therapy, and visual outcomes for a long-term follow-up in a secondary IOL implantation. Methods. Retrospective review of records of all infants with congenital cataracts who underwent secondary IOL implantation in the Eye and ENT Hospital of Fudan University from January 1, 2001, to December 31, 2007, and the minimum follow-up period was 5 years. Multiple regression analysis was used and the possible confounding factors were also analyzed to assess the effect on visual outcome. Results. A total of 110 patients (male: 59.1% were included. The median (min–max age at cataract extraction and IOL implantation was 7.5 (3.0–15.0 and 35.0 (22.0–184.0 months, respectively, and the average follow-up period was 99.3 ± 23.6 months. The median (min–max BCVA at final follow-up was 0.20 (0.01–1.00. Compliance to amblyopia therapy was none, poor, and good in 21.8%, 24.5%, and 53.6%, respectively. Postoperative BCVA [logMAR, median (min–max 0.70 (0.00–2.00] linearly decreased with increasing cataract extraction time (per month (β=0.04, 95% CI: 0.03–0.06, p<0.0001 in multivariable models with laterality and compliance to amblyopia therapy adjusted. Good compliance to amblyopia therapy was associated with better BCVA (logMAR at last follow-up (β=−0.40, 95% CI = −0.53 to −0.27, p<0.0001 with laterality, opacity type, and extraction time adjusted. Conclusions. For Chinese infants with congenital cataract, an earlier primary congenital cataract surgery at an age of 3 to 15 months is associated with a better visual outcome. Good compliance to amblyopia therapy was also significant to visual outcome.

    2002-05-01

    Cataracts are the most frequently seen lens diseases in New World camelids. The causes of cataracts are unknown in many animals, but cataracts secondary to intraocular inflammation seem to be common. Congenital or juvenile-onset cataracts, if another cause is not apparent, should be considered as possibly caused by heredity, and the affected animals should not be bred. Persistent hyaloid vascular anomalies may also have an important role in cataract formation and could be heritable or caused by an in utero disturbance. Pedigree analyses, test breedings, and possibly DNA studies of llamas with cataracts will be required to determine their potential heritability in these species. Cataract surgery can be done successfully in camelids. It is important to evaluate the posterior segment with B scan ultrasonography before surgery in animals in which the posterior segment previously has not been seen. This evaluation allows the surgeon to better prepare for the presence of hyaloid vascular anomalies. Use of phacoemulsification, gentle tissue handling, liberal use of anti-inflammatory medications and endothelial protectants (BSS + and viscoelastics) during surgery has increased the success rate of this surgery in camelids. Unlike cataract surgery in dogs and horses undergoing, cataract surgery, in camelids seems to be important to remove much of the posterior lens capsule. This removal prevents severe capsular fibrosis and subsequent vision loss. There is evidence that a posterior capsulectomy and anterior viterectomy can help prevent postoperative glaucoma. Research needs to be done to see whether these species have an increased risk for ciliary-block glaucoma.

    Full Text Available Introduction Cancer is a worldwide problem as it will affect one in three men and one in four women during their lifetime. Colorectal cancer (CRC is the third most frequent cancer in men, after lung and prostate cancer, and is the second most frequent cancer in women after breast cancer. It is also the third cause of death in men and women separately, and is the second most frequent cause of death by cancer if both genders are considered together. CRC represents approximately 10% of deaths by cancer. Modifiable risk factors of CRC include smoking, physical inactivity, being overweight and obesity, eating processed meat, and drinking alcohol excessively. CRC screening programs are possible only in economically developed countries. However, attention should be paid in the future to geographical areas with ageing populations and a western lifestyle. 19 , 20 Sigmoidoscopy screening done with people aged 55-64 years has been demonstrated to reduce the incidence of CRC by 33% and mortality by CRC by 43%. Objective To assess the effect on the incidence and mortality of CRC diet and lifestyle and to determine the effect of secondary prevention through early diagnosis of CRC. Methodology A comprehensive search of Medline and Pubmed articles related to primary and secondary prevention of CRC and subsequently, a meta-analysis of the same blocks are performed. Results 225 articles related to primary or secondary prevention of CRC were retrieved. Of these 145 were considered valid on meta-analysis: 12 on epidemiology, 56 on diet and lifestyle, and over 77 different screenings for early detection of CRC. Cancer is a worldwide problem as it will affect one in three men and one in four women during their lifetime. There is no doubt whatsoever which environmental factors, probably diet, may account for these cancer rates. Excessive alcohol consumption and cholesterol-rich diet are associated with a high risk of colon cancer. A diet poor in folic acid and vitamin

Fourteen patients (17 eyes with strabismus before cataract surgery were excluded. Patients were divided into those with congenital bilateral cataracts (64 patients, 128 eyes and those with unilateral cataracts (44 patients, 44 eyes. The associations between the development of strabismus and age at cataract surgery, pre- and post-cataract extraction corrected distance visual acuity (CDVA, interocular CDVA difference, nystagmus, surgical method, and secondary cataract were evaluated.RESULTS: Factors significantly associated with the development of strabismus included age at cataract surgery (≤1y, preoperative mean CDVA ≤20/100, presence of nystagmus in the bilateral cataract group and postoperative interocular CDVA difference >20/70 in the unilateral group. Postoperative CDVA ≤20/100 and preservation of posterior capsule, and presence of secondary cataract were significant factors in both groups.CONCLUSION: Children with congenital cataracts should be monitored carefully after cataract surgery for the development of strabismus, especially when they underwent surgery at age ≤1y, and they have nystagmus, large postoperative interocular CDVA difference, poor preoperative and postoperative CDVA, preservation of the posterior capsule, or secondary cataract.

  19. Secondary stroke prevention: challenges and solutions.

    Stroke is the leading cause of disability in the USA and a major cause of mortality worldwide. One out of four strokes is recurrent. Secondary stroke prevention starts with deciphering the most likely stroke mechanism. In general, one of the main goals in stroke reduction is to control vascular risk factors such as hypertension, diabetes, dyslipidemia, and smoking cessation. Changes in lifestyle like a healthy diet and aerobic exercise are also recommended strategies. In the case of cardioembolism due to atrial fibrillation, mechanical valves, or cardiac thrombus, anticoagulation is the mainstay of therapy. The role of anticoagulation is less evident in the case of bioprosthetic valves, patent foramen ovale, and dilated cardiomyopathy with low ejection fraction. Strokes due to larger artery atherosclerosis account for approximately a third of all strokes. In the case of symptomatic extracranial carotid stenosis, surgical intervention as close as possible in time to the index event seems highly beneficial. In the case of intracranial large artery atherosclerosis, the best medical therapy consists of antiplatelets, high-dose statins, aggressive controls of vascular risk factors, and lifestyle modifications, with no role for intracranial arterial stenting or angioplasty. For patients with small artery occlusion (ie, lacunar stroke), the therapy is similar to that used in patients with intracranial large artery atherosclerosis. Despite the constant new evidence on how to best treat patients who have suffered a stroke, the risk of stroke recurrence remains unacceptably high, thus evidencing the need for novel therapies.

    Cataracts in small animals are shown to be at least partially caused by oxidative damage to lens epithelial cells (LECs) and the internal lens; biomarkers of oxidative stress in the lens are considered as general biomarkers for life expectancy in the canine and other animals. Telomeres lengths and expressed telomerase activity in canine LECs may serve as important monitors of oxidative damage in normal LECs with documented higher levels of telomerase activity in cataractous LECs during cells' lifespan. Loss of functional telomere length below a critical threshold in LECs of canines during the effect of UV and chronic oxidative stress or metabolic failure, can activate programs leading to LEC senescence or death. Telomerase is induced in LECs of canines at critical stages of cataractogenesis initiation and exposure to oxidative stress through the involvement of catalytically active prooxidant transition metal (iron) ions. This work documents that transition metal ions (such as, ferrous ions- catalytic oxidants) might induce premature senescence in LECs of canines, telomere shortening with increased telomerase activity as adaptive response to UV light, oxidative and metabolic stresses. The therapeutic treatment with 1% N-acetylcarnosine (NAC) prodrug delivery is beneficial for prevention and dissolution of ripe cataracts in canines. This biological activity is based on the findings of ferroxidase activity pertinent to the dipeptide carnosine released ophthalmically from NAC prodrug of L-carnosine, stabilizing properties of carnosine on biological membranes based on the ability of the imidazole-containing dipeptides to interact with lipid peroxidation products and reactive oxygen species (ROS), to prevent membrane damage and delute the associated with membrane fragements protein aggregates.

    Posterior capsular opacification (PCO) is a common long-term complication of cataract surgery. Intraocular lens design and material have been implicated in influencing the development of PCO. This study evaluated the association of hydrophobic and hydrophilic intraocular lenses on preventing PCO. Medline, Cochrane, EMBASE, and Google Scholar databases were searched until August 3, 2016, using the following search terms: cataract, posterior capsule opacification, and intraocular lens. Eligible studies included randomized controlled trials (RCTs), retrospective, and cohort studies. Eleven studies were included in the study with a total of 889 eyes/patients. The overall analysis revealed that hydrophobic intraocular lenses were associated with lower Nd:YAG laser capsulotomy rates than hydrophilic lenses [odds ratio (OR) = 0.38, 95% confidence interval (95% CI) = 0.16-0.91, P = .029]. Hydrophobic intraocular lenses were also associated with lower subjective PCO score (diff. in means: -1.32, 95% CI = -2.39 to -0.25, P = .015) and estimated PCO score (diff. in means: -2.23; 95% CI, -3.80 to -0.68, P = .005) as compared with hydrophilic lenses. Objective PCO score was similar between lens types. (diff. in means: -0.075; 95% CI, -0.18 to 0.035; P = .182). Pooled analysis found that visual acuity was similar between hydrophobic and hydrophilic intraocular lenses (diff. in means: -0.016; 95% CI, -0.041 to 0.009, P = .208). In general, PCO scores and the rate of Nd:YAG laser capsulotomy were influenced by intraocular lens biomaterial. Lens made of hydrophobic biomaterial were overall superior in lowering the PCO score and the Nd:YAG laser capsulotomy rate, but not visual acuity.

    When this paper was about to go to press, the International Commission on Radiological Protection released a statement recommending a change in the threshold dose for the eye lens and dose limits for eye for occupationally exposed persons. It is clear that the earlier published threshold for radiation cataract is no longer valid. Epidemiological studies among Chernobyl clean-up workers, A bomb survivors, astronauts, residents of contaminated buildings, radiological technicians and recent surveys of staff in interventional rooms indicate that there is an increased incidence of lens opacities at doses below 1 Gy. Nevertheless, eye lens dosimetry is at a primitive stage and needs to be developed further. Despite uncertainties concerning dose threshold and dosimetry, it is possible to significantly reduce the risk of radiation cataract through the use of appropriate eye protection. By increasing awareness among those at risk and better adoption and increased usage of protective measures, radiation cataract can become preventable despite lowering of dose limits. (authors)

    In the province of Saskatchewan, Canada, stroke is the third leading cause of death as well as the major cause of adult disability. Once a person suffers a stroke or transient ischemic attack (TIA), they are at high risk for having a secondary stroke. Hypertension (elevated blood pressure) is the single most important modifiable risk factor for both first and recurrent stroke, and is thus an important risk factor to be controlled. According to the Canadian Stroke Strategy (CSS) Best Practice Recommendations, blood pressure lowering treatment should be initiated before discharge from hospital for all stroke/TIA patients. The purpose of this study was to examine the quality of medically driven secondary stroke prevention care in Saskatchewan as applied to hypertension control. The objectives of the study were to: (1) develop methodology and calculate a secondary stroke process of care measure using available data in Saskatchewan, based on an appropriate hypertension therapy indicator recommendation from the CSS Performance Measurement Manual; (2) examine variation in secondary stroke prevention hypertensive care among the Saskatchewan Regional Health Authorities; and (3) investigate factors associated with receiving evidence-based hypertensive secondary stroke prevention. This multi-year cross-sectional study was an analysis of deidentified health data derived from linkage of administrative health data. A select indicator from the CSS Performance Measurement Manual that measures adherence to a CSS Best Practice Guidelines concerning use of antihypertensive medications for secondary stroke prevention was calculated. Logistic regression was used to quantify the association of patient demographic and socioeconomic characteristics and geographic location of care with receipt of guideline-recommended hypertensive secondary stroke prevention. The target population was all Saskatchewan residents who were hospitalized in Saskatchewan for a stroke or TIA between April 1, 2001

    To determine if pretreatment with topical nonsteroidal anti-inflammatory drug (NSAID) prior to femtosecond laser-assisted cataract surgery (FLACS) prevents intraoperative prostaglandin level elevation as a potential risk factor of postoperative complications. Thirty-six patients with clinically significant cataract and without any concomitant general or ophthalmic disease were enrolled into the three age-matched groups of the study. The mean age of the patients was 62.3 ± 13.1 years. The first group of patients underwent traditional phacoemulsification (Control group), on the second group of patients FLACS was performed, and the third group of patients received topical 0.1% nepafenac pretreatment for 1one day prior to FLACS. Before the phacoemulsification part of the cataract surgery, approximately 110 µL of aqueous humor was collected in all groups. Total prostaglandin concentrations of the collected aqueous humor samples were evaluated by enzyme immunoassay (EIA). The mean of the total prostaglandin concentrations of the aqueous humor samples was 208.8 ± 140.5 pg/mL in patients in the control group, 1449.1 ± 1019.7 pg/mL in the FLACS group (p > 0.001), and 92.2 ± 51.7 pg/mL in the group pretreated with topical NSAID before the FLACS (p > 0.001 compared to FLACS; p > 0.01 compared to control), respectively. FLACS surgery increases intracameral prostaglandin concentration. However, using preoperative 1-day-long nonsteroid anti-inflammatory drops prior to FLACS, this intraoperative increase diminishes. Our study raises the possibility that NSAID pretreatment may be routinely administered before FLACS cataract surgeries to achieve a further decrease in the potential complications of increased total prostaglandin concentration during FLACS surgeries.

    Full Text Available Here is identified the tendency to reduce the effectiveness of anti-tobacco prevention work among graduating students of secondary school. This decline may be due to psychological and social reasons. It is shown that risk factors of involving in chemical dependency are meaningfully disclosed in longitudinal studies, whereas the dynamics of personal change during the formation of anti-addictive prevention skills are more fully disclosed in the comparative age sections. The typical phenomena, accompanying the downward trend in prevention, are the growth of problem behavior and the crisis of mass dropout. Such phenomena are so great that they are recognized as a crisis at a state level.

  19. Sutureless Cataract Surgery: Principles and Steps

    Directory of Open Access Journals (Sweden)

    John Sandford-Smith

    2003-01-01

    Full Text Available Introduction. Cataracts cause about 50% of world blindness. There is little likelihood of effective prevention becoming available in the next few years and so the only treatment will remain surgical. For many of the other major causes of world blindness, like trachoma, xerophthalmia and onchocerciasis, the remedy is community-based, not hospital-based, and requires prevention rather than treatment. The prevalence of blinding cataract will only increase as people live longer, so cataract will continue to be, by far, the most important treatable cause of blindness.

    "Get With The Guidelines (GWTG)" was developed and piloted by the American Heart Association (AHA), New England Affiliate; MassPRO, Inc.; and other organizations to reduce the gap in the application of secondary prevention guidelines in hospitalized cardiovascular disease patients. Collaborative learning programs and technology solutions were created for the project. The interactive Web-based patient management tool (PMT) was developed using quality measures derived from the AHA/American College of Cardiology secondary prevention guidelines. It provided data entry, embedded reminders and guideline summaries, and online reports of quality measure performance, including comparisons with the aggregate performance of all hospitals. Multidisciplinary teams from 24 hospitals participated in the 2000-2001 pilot. Four collaborative learning sessions and monthly conference calls supported team interaction. Best-practices sharing and the use of an Internet tool enabled hospitals to change systems and collect data on 1,738 patients. The GWTG program, a template of learning sessions with didactic presentations, best-practices sharing, and collaborative multidisciplinary team meetings supported by the Internet-based data collection and reporting system, can be extended to multiple regions without requiring additional development. Following the completion of the pilot, the AHA adopted GWTG as a national program.

    The objective of this study was to evaluate the impact of the prescription of secondary prevention therapies on mortality in Puerto Rican patients hospitalized with a first ischemic stroke. This was a retrospective secondary data analysis of the 2007 and 2009 Puerto Rico Stroke Registry electronic database. Information was obtained from the medical charts of patients discharged with ICD-9 codes 434 and 436 from 20 hospitals located in Puerto Rico. Descriptive analyses were conducted for demographics and comorbidities. Chi2 statistics compared the proportion of patients prescribed secondary prevention therapy and the proportion of patients not prescribed secondary prevention therapy. Lastly, survival rates were calculated from 2007 up to and including December 2010. The mean age of the 3,965 patients was 70 (±14) years. Secondary prevention therapy was prescribed to only 1% of the patients. The most frequent comorbidities were hypertension (85%), diabetes (52%), and hyperlipidemia (25%). The case fatality rate for patients prescribed secondary prevention therapy was 16%, compared to 26% for patients not prescribed secondary prevention therapy (p<0.01). The mean survival for stroke patients prescribed secondary preventions was 450 days (95% CI;182−718), compared to 266 days (95% CI; 244−287) for those not prescribed secondary prevention therapy (p = 0.175). A low percentage of patients with a first ischemic stroke were prescribed secondary prevention therapy. While not statistically significant, survival analysis suggests that secondary prevention therapy decreased mortality in patients with a stroke.

    Full Text Available AIM: To explore the associations between various characteristics of Malaysian cataract patients and their management, and their post-operative visual outcomes, to inform relevant bodies to reduce cataract-related blindness. METHODS: We conducted a descriptive secondary data analysis of cataract surgery patients in Melaka Hospital, from 2007 to 2014 using the National Eye Database (NED. Patient-related factors (demographic features, systemic and ocular comorbidities and management-related factors (surgical duration, type of surgery, type of lens were analysed for their association with visual outcome (acuity. RESULTS: Most patients were Malays (48.23% and Chinese (38.55% aged 60-79y (range 0-100y. Hypertension (58.61% and diabetes (44.89% were major systemic comorbidities. Glaucoma (6.71% and diabetic retinopathy (10.12% were the main ocular comorbidities. Other comorbidities were age-related macular degeneration, pterygium, corneal opacities, macula diseases, vitreous haemorrhage, retinal detachment and pseudoexfoliation (0.70%-1.60%. Preoperatively 7150 (55.03% eyes presented with poor vision. Uncomplicated phacoemulsification performed quickly with foldable lenses gave good results. CONCLUSION: Primary care physicians should initiate early detection to prevent late presentation of cataracts causing poor vision and should discuss the risks and benefits of cataract surgery while emphasizing the role of pre-existing comorbidities which may affect the visual outcomes. For good results, phacoemulsification should be done within 30min, without complications, using foldable posterior chamber intraocular lens.

    Fibrates are a class of drugs characterised by mainly lowering high triglyceride, raising high-density lipoprotein (HDL) cholesterol, and lowering the small dense fraction of low-density lipoprotein (LDL) cholesterol. Their efficacy for secondary prevention of serious vascular events is unclear, and to date no systematic review focusing on secondary prevention has been undertaken. To assess the efficacy and safety of fibrates for the prevention of serious vascular events in people with previous cardiovascular disease (CVD), including coronary heart disease and stroke. We searched the Cochrane Central Register of Controlled Trials (CENTRAL; Issue 9, 2014) on the Cochrane Library, MEDLINE (OVID, 1946 to October week 1 2014), EMBASE (OVID, 1980 to 2014 week 41), the China Biological Medicine Database (CBM) (1978 to 2014), the Chinese National Knowledge Infrastructure (CNKI) (1979 to 2014), Chinese Science and Technique Journals Database (VIP) (1989 to 2014). We also searched other resources, such as ongoing trials registers and databases of conference abstracts, to identify further published, unpublished, and ongoing studies. We included randomised controlled trials (RCTs) in which a fibrate (for example gemfibrozil, fenofibrate) was compared with placebo or no treatment. We excluded RCTs with only laboratory outcomes. We also excluded trials comparing two different fibrates without a placebo or no-treatment control. Two review authors independently selected trials for inclusion, assessed risk of bias, and extracted the data. We contacted authors of trials for missing data. We included 13 trials involving a total of 16,112 participants. Eleven trials recruited participants with history of coronary heart disease, two trials recruited participants with history of stroke, and one trial recruited participants with a mix of people with CVD. We judged overall risk of bias to be moderate. The meta-analysis (including all fibrate trials) showed evidence for a protective

    2004-08-01

    It is conservatively estimated that some form of lens opacity is present in 5% to 7% of horses with otherwise clinically normal eyes.These opacities can range from small epicapsular remnants of the fetal vasculature to dense and extensive cataract. A cataract is defined technically as any opacity or alteration in the optical homogeneity of the lens involving one or more of the following: anterior epithelium, capsule, cortex, or nucleus. In the horse, cataracts rarely involve the entire lens structure (ie, complete cataracts) and are more usually localized to one anatomic landmark or sector of the lens. Complete cataracts are invariably associated with overt and significant visual disability. Focal or incomplete cataracts alone seldom cause any apparent visual dysfunction in affected horses,however.

    Eye disturbance caused by atomic bomb radiation can be divided into three groups: direct injury immediately after exposure, eye lesions associated with radiation syndrome, and delayed disturbance. The crystalline lens of the eye is the most radiosensitive. Atomic bomb cataract has been investigated in a number of studies. The first section of this chapter discusses radiation cataract in terms of the incidence and characteristics. The second section deals with atomic bomb cataract, which can be diagnosed based on the four criteria: (1) opacity of the crystalline lens, (2) a history of proximal exposure, (3) lack of eye disease complicating cataract, and (4) non-exposure to radiation other than atomic bombing. The prevalence of cataract and severity of opacity are found to correlate with exposure doses and age at the time of exposure. Furthermore, it is found to correlate with distance from the hypocenter, the condition of shielding, epilation, and the presence or absence or degree of radiation syndrome. (N.K.)

    To study the clinical profile and presentation of children with unilateral cataract. In this hospital-based, observational, cross-sectional study, patients 15 years of age or younger who presented with unilateral cataract were recruited. Cases of cataract secondary to causes such as trauma or uveitis were excluded. Age at detection and presentation, distance from the treatment center, presenting complaints, cataract morphology, and biometry were noted for each case. A total of 76 patients were recruited. Most patients presented with complaints of leukocoria. Persistent fetal vasculature accounted for 27.6% of cases and was the most common identifiable cause of cataract in this study. Subsequently, patients were divided into two groups: no persistent fetal vasculature (control) and persistent fetal vasculature. A male predominance was noted in both groups. The mean age at detection was 27.58 ± 37.02 and 6.17 ± 8.42 months and the mean age at presentation was 55.613 ± 45.21 and 14.83 ± 17.75 months in the control and persistent fetal vasculature groups, respectively. In the persistent fetal vasculature group, a significant difference was noted in the axial length, keratometry, and corneal diameter between the affected and normal eyes (P = .027, .00176, and .0114, respectively). In the control group, this difference was observed only in keratometry readings (P = .0464). The mean distance traveled by patients to reach the treatment center was 211 km. Persistent fetal vasculature is an important and less identified cause of unilateral cataract. A significant delay is noted in the detection and presentation of unilateral cataract.

    Prevention plays an important role in achieving the triple aim of decreasing per capita health care costs, improving the health of populations, and bettering the patient experience. Primary care is uniquely positioned to provide preventive services. External forces are aligning to support the transition of primary care from traditional models focused on disease-specific, acute episodes of care to new ways of organizing that are more patient centered, team based, and quality driven. By aligning leadership, building change capacity, and selectively choosing relevant processes to change, those practicing primary care can successfully organize their practice environment to deliver preventive services.

    2012-01-01

    Full Text Available Cataract surgery in uveitic eyes is often challenging and can result in intraoperative and postoperative complications. Most uveitic patients enjoy good vision despite potentially sight-threatening complications, including cataract development. In those patients who develop cataracts, successful surgery stems from educated patient selection, careful surgical technique, and aggressive preoperative and postoperative control of inflammation. With improved understanding of the disease processes, pre- and perioperative control of inflammation, modern surgical techniques, availability of biocompatible intraocular lens material and design, surgical experience in performing complicated cataract surgeries, and efficient management of postoperative complications have led to much better outcome. Preoperative factors include proper patient selection and counseling and preoperative control of inflammation. Meticulous and careful cataract surgery in uveitic cataract is essential in optimizing the postoperative outcome. Management of postoperative complications, especially inflammation and glaucoma, earlier rather than later, has also contributed to improved outcomes. This manuscript is review of the existing literature and highlights the management pearls in tackling complicated cataract based on medline search of literature and experience of the authors.

    Full Text Available Cataract is the leading cause of 51% blindness case in the world. Cataract can only be cured trough surgery, but most people with cataract in Indonesia is not in undergoing surgery due to several factors. The increasing number of cataract victim whose not undergoing any treatment to cure them will resulting in increasing number of blindness case, so blindness cause by cataracts can be a public health problem. This research was conducted to determine the relationship of age, attitudes, knowledge and the cost of the action to perform cataract surgery. This research was an observational analytic study with cross sectional design. The samples were cataract patients in Undaan Eye Hospital Surabaya who were randomly selected using a simple random sampling based on medical records of 60 people. Data collection was done by taking secondary data and interviews to patients. Those variables was analyzed with chi square or Fisher’s exact with significancy level at 95%. The result showed that there were correlation between knowledge (p = 0.017, operating costs (p = 0.001 and attitude (0.000 while age was not related (p = 1.000, the actions to perform cataract surgery. The conclusion from this research was the attitude, knowledge and operating costs related to the actions to perform cataract surgery, while age was not related to the actions to perform cataract surgery.

    Full Text Available Guy SalletDepartment of Opthamology, Aalsters Stedelijk Ziekenhuis, BelgiumAbstract: A cataract surgery technique is described in which incisions, continuous circular capsulorhexis and hydrodissection are made without the use of any viscoelastics. Two small incisions are created through which the different parts of the procedure can take place, maintaining a stable anterior chamber under continuous irrigation. Subsequent bimanual phacoemulsification can be done through these microincisions. At the end of the procedure, an intraocular lens can be inserted through the self-sealing incision under continuous irrigation. 50 consecutive cataract patients were operated on without the use of viscoelastics and then compared with a group of 50 patients who had been helped with viscoelastics. No difference in outcome, endothelial cell count or pachymetry was noted between the two groups. No intraoperative complication was encountered. Viscoless cataract surgery was a safe procedure with potential advantages.Keywords: ophthalmic visco-surgical device, viscoless cataract surgery, microincision

  4. Using Misoprostol for Primary versus Secondary Prevention of Postpartum Haemorrhage - Do Costs Matter?

    2016-01-01

    Postpartum heammorrhage (PPH), defined as blood loss greater than or equal to 500 ml within 24 hours after birth, is the leading cause of maternal deaths globally and in India. Misoprostol is an important option for PPH management in setting where oxytocin (the gold standard for PPH prevention and treatment) in not available or not feasible to use. For the substantial number of deliveries which take place at home or at lower level heatlh facilities in India, misoprostol pills can be adminstered to prevent PPH. The standard approach using misoprostol is to administer it prophylactically as primary prevention (600 mcg). An alternative strategy could be to administer misoprostol only to those who are at high risk of having PPH i.e. as secondary prevention. This study reports on the relative cost per person of a strategy involving primary versus secondary prevention of PPH using misoprostol. It is based on a randomized cluster trial that was conducted in Bijapur district in Karnataka, India between December 2011 and March 2014 among pregnant women to compare two community-level strategies for the prevention of PPH: primary and secondary. The analysis was conducted from the government perspective using an ingredient approach. The cluster trial showed that there were no significant differences in clinical outcomes between the two study arms. However, the results of the cost analysis show that there is a difference of INR 6 (US$ 0.1) per birth for implementing the strategies primary versus secondary prevention. In India where 14.9 million births take place at sub-centres and at home, this additional cost of INR 6 per birth translates to an additional cost of INR 94 (US$ 1.6) million to the government to implement the primary prevention compared to the secondary prevention strategy.

    Full Text Available Purpose. We present a case of a patient with Soemmering ring after cataract surgery and a potential complication that can arise as a result of its presence. Observations. A patient with history of ruptured globe status after repair and lensectomy, complicated by aphakic secondary open angle glaucoma, was referred for management of second injury to the same eye. This injury resulted in Soemmering ring dislocation into the anterior chamber. The cortical material caused a significant increase in intraocular pressure and corneal decompensation. Surgical removal of the Soemmering ring and Ahmed glaucoma tube implant was performed with control of intraocular pressures; however corneal edema could not be reversed. Conclusions and Importance. This case report illustrates the serious consequences that can be caused by Soemmering rings without early surgical intervention. Care must be taken to completely remove cortical material during cataract surgery to prevent their formation.

    Despite being a treatable disease, cataract is still the leading cause for blindness in the world. Solar ultraviolet radiation is epidemiologically linked to cataract development, while animal and in vitro studies prove a causal relationship. However, the pathogenetic pathways for the disease are not fully understood and there is still no perfect model for human age related cataract. This non-comprehensive overview focus on recent developments regarding effects of solar UV radiation wavebands on the lens. A smaller number of fundamental papers are also included to provide a backdrop for the overview. Future studies are expected to further clarify the cellular and subcellular mechanisms for UV radiation-induced cataract and especially the isolated or combined temporal and spatial effects of UVA and UVB in the pathogenesis of human cataract. Regardless of the cause for cataract, there is a need for advances in pharmaceutical or other treatment modalities that do not require surgical replacement of the lens. Copyright © 2016.

    Full Text Available BACKGROUND Control of childhood blindness is one of the priorities identified for achieving the goals of Vision-2020 by WHO. This is considered a priority because blind-years (number of years that a blind person lives after going blind due to childhood blindness are second only to cataract and half of childhood blindness is avoidable (treatable/preventable. Paediatric cataract accounts for 12% of the 1.4 million blind children globally. The prevalence of childhood cataract has been reported as 1 to 15 cases in 10,000 children in developing countries. Compared to industrialised countries, this figure is 10 times higher. Early detection and timely treatment of various childhood disorders such as congenital cataract are the most crucial factors for successful outcome. A suitable measure to address amblyopia and posterior capsule opacification post operatively is imperative for successful visual rehabilitation of such children. The objectives of this study were- 1 To study the clinical profile of paediatric cataract. 2 To evaluate the visual outcome after cataract surgery in these patients. 3 To evaluate different causes of visual impairment following management. MATERIALS AND METHODS A prospective study conducted at Karnataka institute of medical sciences department of ophthalmology from October 2015 to September 2016. All children below 14 years of age presenting with cataract will undergo thorough ophthalmologic examination and cataract surgery. RESULTS The results of the present study with 25 paediatric patients (36 eyes indicates that excellent vision can be expected after cataract surgery and posterior chamber IOL implantation coupled with appropriate amblyopia therapy. CONCLUSION The paediatric cataract patients are referred from primary health centers, and district hospital from north Karnataka to KIMS Hubli. All paediatric patients are from lower socio economic status. Early detection of cataracts and referrals to the ophthalmologist can

    Full Text Available Vitamin K antagonists, such as warfarin, used in oral anticoagulation therapy currently represent the standard drugs for the primary and secondary prevention of stroke in non-valvular atrial fibrillation (AF, with a relative risk reduction close to 70%. Newer oral anticoagulants, such as direct thrombin inhibitors (i.e., dabigatran and direct factor Xa inhibitors (i.e., apixaban and rivaroxaban have been recently compared with warfarin in large randomized trials for stroke prevention in AF. The new oral anticoagulants showed, compared with warfarin, no statistically significant difference in the rate of stroke or systemic embolism in secondary prevention (patients with previous transient ischemic attack or stroke subgroups. With regard to safety, the risk of intracranial bleeding was reduced with new anticoagulants compared with warfarin. Indirect treatment comparisons of clinical trials on secondary prevention cohorts showed no significant difference in efficacy among apixaban, rivaroxaban, and dabigatran; but dabigatran 110 mg was associated with less intracranial bleedings than rivaroxaban.

    The author wanted to test the effects of preventive mental health programmes in schools and established a longitudinal study with a test group and a control group, using Solomon's method. Data was collected through questionnaires prior to intervention and at 1, 6, 12, and 24 months after the intervention. The size of the effect on the various indices were estimated in terms of (a) differences in improvement of total percentage scores and (b) Cohen's d. From to to t1, t2 and t3 the intervention group showed significantly greater progress in six out of seven knowledge indexes, and 12 months later we found significant effects on the level of mental health problems.

  12. ANTITHROMBOCYTIC THERAPY IN THE SECONDARY PREVENTION OF ISCHEMIC STROKE

    2009-01-01

    Full Text Available Approaches to preventing recurrent stroke by antithrombocytic therapy are shown to be as diverse as its causes. The diagnosis of cardioembolic stroke in patients with atrial fibrillation should not limit the choice of an antithrombocytic agent to only oral (indirect anticoagulants (OAC. If OAC cannot be used, antithrombocytic therapy, including combined (clopidogrel + ASA one, may be considered as a reasonable alternative. Approaches to choosing the optimal antithrombocytic drug in noncardioembolic strokes are intricate since atherosclerosis is a systemic vascular disease and the poststroke period is characterized by a higher risk for not only recurrent stroke, but also for coronary catastrophes. It is concluded that an antithrombocytic agent should be chosen, by taking into account the multifocality of atherosclerosis, associated clinical conditions, diabetes mellitus, intravascular interventions and the individual risk of all cardiovascular events.

    BACKGROUND: In patients with ischemic stroke of non-cardioembolic origin, acetylsalicylic acid, clopidogrel, or a combination of acetylsalicylic acid and dipyridamole are recommended for the prevention of a recurrent stroke. The purpose of this study was to examine the risk of bleeding or recurrent...... stroke associated with these three treatments. METHODS: Patients who were discharged with first-time ischemic stroke from 2007-2010, with no history of atrial fibrillation were identified from Danish nationwide registries. Hazard ratios (HRs) and 1-year risks of recurrent ischemic stroke and bleeding...... were calculated for each antiplatelet regimen. RESULTS: Among patients discharged after first-time ischemic stroke, 3043 patients were treated with acetylsalicylic acid, 12,295 with a combination of acetylsalicylic acid and dipyridamole, and 3885 with clopidogrel. Adjusted HRs for clopidogrel versus...

  14. Role of depression in secondary prevention of Chinese coronary heart disease patients receiving percutaneous coronary intervention.

    Can Feng

    Full Text Available Coronary heart disease (CHD patients who have undergone percutaneous coronary intervention (PCI have higher rates of depression than the general population. However, few researchers have assessed the impact of depression on the secondary prevention of CHD in China.The main purpose of this investigation was to explore the relationship between depression and secondary prevention of CHD in Chinese patients after PCI.This descriptive, cross-sectional one-site study recruited both elective and emergency PCI patients one year after discharge. Data from 1934 patients were collected in the clinic using questionnaires and medical history records between August 2013 and September 2015. Depression was evaluated by the 9-item Patient Health Questionnaire. Secondary prevention of CHD was compared between depression and non-depression groups.We found that depression affected secondary prevention of CHD in the following aspects: lipid levels, blood glucose levels, smoking status, physical activity, BMI, and rates of medication use.Depressive patients with CHD are at increased risk of not achieving the lifestyle and risk factor control goals recommended in the 2006 AHA guidelines. Screening should focus on patients after PCI because treating depression can improve outcomes by improving secondary prevention of CHD.

    2015-02-01

    The introduction of an increasing number of individualized molecular targeted therapies into clinical routine mirrors their importance in modern cancer prevention and treatment. Well-known examples for targeted agents are the monoclonal antibody trastuzumab and the selective estrogen receptor modulator tamoxifen. The identification of an unaltered gene in tumor tissue in colon cancer (KRAS) is a predictor for the patient's response to targeted therapy with a monoclonal antibody (cetuximab). Targeted therapy for hereditary breast and ovarian cancer has become a reality with the approval of olaparib for platin-sensitive late relapsed BRCA-associated ovarian cancer in December 2014. This manuscript reviews the status quo of poly-ADP-ribose polymerase inhibitors (PARPi) in the therapy of breast and ovarian cancer as well as the struggle for carboplatin as a potential standard of care for triple-negative and, in particular, BRCA-associated breast cancer. Details of the mechanism of action with information on tumor development are provided, and an outlook for further relevant research is given. The efficacy of agents against molecular targets together with the identification of an increasing number of cancer-associated genes will open the floodgates to a new era of treatment decision-making based on molecular tumor profiles. Current clinical trials involving patients with BRCA-associated cancer explore the efficacy of the molecular targeted therapeutics platinum and PARPi.

    2011-10-01

    Urinary tract infections (UTI) are among the most frequent bacterial infections in the community and health care setting. Mostly young and, to some extent, postmenopausal women are affected by recurrent UTI (rUTI) defined as ≥3 UTI/year. On the other hand rUTI are frequently found in patients with complicating urological factors, e.g. urinary catheters. Modifiable predisposing factors in uncomplicated rUTI in women are rare. Continuous antibiotic prophylaxis or postcoital prophylaxis, if there is close correlation with sexual intercourse, are most effective to prevent rUTI. Nitrofurantoin, trimethoprim (or cotrimoxazole), and fosfomycin trometamol are available as first-line drugs. Oral cephalosporins and quinolones should be restricted to specific indications. Antibiotic prophylaxis reduces the number of uropathogens in the gut and/or vaginal flora and reduces bacterial"fitness". Given the correct indication, the recurrence rate of rUTI can be reduced by about 90%. In postmenopausal patients vaginal substitution of oestriol should be started first. Oral or parenteral immunoprophylaxis is another option in patients with rUTI. Other possibilities with varying scientific evidence are prophylaxis with cranberries or probiotics. The prophylaxis of catheter-associated UTI or asymptomatic bacteriuria should employ strategies which result in a reduction of frequency and duration of catheter drainage of the urinary tract. The currently available catheter materials have only little influence on reducing catheter-associated rUTI.

    This paper reports orbital CT scans of 15 patients with clinically diagnoses traumatic cataracts retrospectively reviewed to determine the presence of radiographically detectable lens abnormalities. Definite lens swelling was clinically observed in a lease five cases. Eleven patients, scanned 4 hours of 3 days after injury, revealed visible and measured decreased CT density of the cataractous lens compared with the normal contralateral lens (average mean difference, 28 HU), suggesting acute lens swelling. In one patient, lens morphologic changes but not HU differences were found, probably due to superimposed hemorrhage. Three patients, scanned 3-8 hours after injury, revealed no detectable lens abnormality. The findings suggest that CT is potentially capable of identifying traumatic cataracts

    This article discusses the ethical, practical, and moral issues surrounding secondary prevention efforts of child sexual abuse from a professional and practice-based perspective. Transcripts of a semistructured consultation event with n = 15 international experts on the secondary prevention of child sexual abuse were analysed using thematic qualitative analysis. The research identified four main critical areas linked to secondary prevention efforts, including, the psychology of self-reporting and disclosure; the interaction with and within existing legal, social, and professional frameworks; the scale and type of an appropriate response; and potential hurdles (i.e., within media, public, politics). The article outlines these areas, highlighting participant perspectives on risk-enhancing and mitigating factors for each domain.

    UVB radiation from sunlight is known to be a risk factor for human cataract. The purpose in this study was to investigate the ability of a class I UV-blocking soft contact lens to protect against UVB-induced effects on the ocular tissues of the rabbit in vivo. Eyes of rabbits were exposed to UVB light for 30 minutes (270-360 nm, peak at 310 nm, 1.7 mW/cm(2) on the cornea). Eyes were irradiated in the presence of either a UV-blocking senofilcon A contact lens, a minimally UV-blocking lotrafilcon A contact lens, or no contact lens at all. Effects on the cornea and lens were evaluated at various times after exposure. Eyes irradiated with no contact lens protection showed corneal epithelial cell loss plus lens epithelial cell swelling, vacuole formation, and DNA single-strand breaks, as well as lens anterior subcapsular opacification. The senofilcon A lens protected nearly completely against the UVB-induced effects, whereas the lotrafilcon A lens showed no protection. The results indicate that use of a senofilcon A contact lens is beneficial in protecting ocular tissues of the rabbit against the harmful effects of UVB light, including photokeratitis and cataract.

    Worldwide, stroke is the leading cause of mortality and disability, with hypertension being an independent risk factor for a secondary stroke. Acupuncture for the treatment of hypertension gains more attention in alternative and complementary medicine, but the results are inconsistent. Few studies regarding the secondary prevention of stroke by managing hypertension with acupuncture have been carried out as there are some problems regarding the antihypertensive drug status in the secondary prevention of stroke. Still, the potential of acupuncture in regulating the blood pressure for secondary stroke prevention deserves our focus. This review is based on papers recorded in the PubMed, Embase, and Web of Science databases, from their inception until March 28, 2017, and retrieved with the following search terms: hypertension and acupuncture, limited in spontaneously hypertensive rats (SHRs), stress-induced (or cold-induced) hypertensive or pre-hypertensive models. We find that, in these hypertensive animals, acupuncture could mainly influence factors related to the nervous system, oxidative stress, the endocrine system, cardiovascular function, and hemorheology, which are closely associated with the stroke outcome. This trend may give us a hint that acupuncture might well participate in the secondary prevention of stroke through these pathways when used in the management of hypertension. © 2018 S.

    Hypertrophic cardiomyopathy is a frequent cause of sudden death. Clinical practice guidelines indicate defibrillator implantation for primary prevention in patients with 1 or more risk factors and for secondary prevention in patients with a history of aborted sudden death or sustained ventricular arrhythmias. The aim of the present study was to analyze the follow-up of patients who received an implantable defibrillator following the current guidelines in nonreferral centers for this disease. This retrospective observational study included all patients who underwent defibrillator implantation between January 1996 and December 2012 in 3 centers in the province of Barcelona. The study included 69 patients (mean age [standard deviation], 44.8 [17] years; 79.3% men), 48 in primary prevention and 21 in secondary prevention. The mean number of risk factors per patient was 1.8 in the primary prevention group and 0.5 in the secondary prevention group (P=.029). The median follow-up duration was 40.5 months. The appropriate therapy rate was 32.7/100 patient-years in secondary prevention and 1.7/100 patient-years in primary prevention (P<.001). Overall mortality was 10.1%. Implant-related complications were experienced by 8.7% of patients, and 13% had inappropriate defibrillator discharges. In patients with a defibrillator for primary prevention, the appropriate therapy rate is extremely low, indicating the low predictive power of the current risk stratification criteria.

    A number of registry studies have reported suboptimal adherence to guidelines for cardiovascular prevention during the first year after acute myocardial infarction (AMI). However, only a few studies have addressed long-term secondary prevention after AMI. This study evaluates prevention guideline adherence and outcome of guideline-directed secondary prevention in patients surviving 2 years after AMI. Patients aged 18-85 years at the time of their index AMI were consecutively identified from hospital discharge records between July 2010 and December 2011 in Gothenburg, Sweden. All patients who agreed to participate in the study (16.2%) were invited for a structured interview, physical examinations and laboratory analysis 2 years after AMI. Guideline-directed secondary preventive goals were defined as optimally controlled blood pressure, serum cholesterol, glucose, regular physical activity, smoking cessation and pharmacological treatment. The mean age of the study cohort (n = 200) at the index AMI was 63.0 ± 9.7 years, 79% were men. Only 3.5% of the cohort achieved all six guideline-directed secondary preventive goals 2 years after infarction. LDL therapy was used by 97% of the patients, beta-blockers by 83.0%, angiotensin-converting enzyme inhibitors/angiotensin receptor blockers by 76.5% and statins by 88.5%. During follow-up, non-fatal adverse cardiovascular events (cardiac hospitalization, recurrent acute coronary syndrome, angina pectoris, new percutaneous coronary intervention, new onset of atrial fibrillation, post-infarct heart failure, pacemaker implantation, stroke/transient ischemic attack (TIA), cardiac surgery and cardiac arrest) occurred in 47% of the cohort and readmission due to cardiac causes in 30%. Our data showed the failure of secondary prevention in our daily clinical practice and high rate of non-fatal adverse cardiovascular events 2 years after AMI.

    Osteoporosis is a major public health concern affecting an estimated 10 million people in the United States. To the best of our knowledge, no qualitative study has explored barriers perceived by medicine hospitalists to secondary prevention of osteoporotic hip fractures. We aimed to describe these perceived barriers and recommendations regarding how to optimize secondary prevention of osteoporotic hip fracture. In-depth, semistructured interviews were performed with 15 internal medicine hospitalists in a tertiary-care referral medical center. The interviews were analyzed with directed content analysis. Internal medicine hospitalists consider secondary osteoporotic hip fracture prevention as the responsibility of outpatient physicians. Identified barriers were stratified based on themes including physicians' perception, patients' characteristics, risks and benefits of osteoporosis treatment, healthcare delivery system, and patient care transition from the inpatient to the outpatient setting. Some of the recommendations include building an integrated system that involves a multidisciplinary team such as the fracture liaison service, initiating a change to the hospital policy to facilitate inpatient care and management of osteoporosis, and creating a smooth patient care transition to the outpatient setting. Our study highlighted how internal medicine hospitalists perceive their role in the secondary prevention of osteoporotic hip fractures and what they perceive as barriers to initiating preventive measures in the hospital. Inconsistency in patient care transition and the fragmented nature of the existing healthcare system were identified as major barriers. A fracture liaison service could remove some of these barriers.

  7. Using Misoprostol for Primary versus Secondary Prevention of Postpartum Haemorrhage - Do Costs Matter?

    Susmita Chatterjee

    Full Text Available Postpartum heammorrhage (PPH, defined as blood loss greater than or equal to 500 ml within 24 hours after birth, is the leading cause of maternal deaths globally and in India. Misoprostol is an important option for PPH management in setting where oxytocin (the gold standard for PPH prevention and treatment in not available or not feasible to use. For the substantial number of deliveries which take place at home or at lower level heatlh facilities in India, misoprostol pills can be adminstered to prevent PPH. The standard approach using misoprostol is to administer it prophylactically as primary prevention (600 mcg. An alternative strategy could be to administer misoprostol only to those who are at high risk of having PPH i.e. as secondary prevention.This study reports on the relative cost per person of a strategy involving primary versus secondary prevention of PPH using misoprostol. It is based on a randomized cluster trial that was conducted in Bijapur district in Karnataka, India between December 2011 and March 2014 among pregnant women to compare two community-level strategies for the prevention of PPH: primary and secondary. The analysis was conducted from the government perspective using an ingredient approach.The cluster trial showed that there were no significant differences in clinical outcomes between the two study arms. However, the results of the cost analysis show that there is a difference of INR 6 (US$ 0.1 per birth for implementing the strategies primary versus secondary prevention. In India where 14.9 million births take place at sub-centres and at home, this additional cost of INR 6 per birth translates to an additional cost of INR 94 (US$ 1.6 million to the government to implement the primary prevention compared to the secondary prevention strategy.As clinical outcomes did not differ significantly between the two arms in the trial, taking into account the difference in costs and potential issues with sustainability, secondary

    To present descriptive epidemiology of cataract surgery among Medicare recipients in the United States. Cataract surgery performed on Medicare beneficiaries in 2003 and 2004. Medicare claims data were used to identify all cataract surgery claims for procedures performed in the United States in 2003-2004. Standard assumptions were used to limit the claims to actual cataract surgery procedures performed. Summary statistics were created to determine the number of procedures performed for each outcome of interest: cataract surgery rates by age, sex, race and state; surgical volume by facility type and surgeon characteristics; time interval between first- and second-eye cataract surgery. The national cataract surgery rate for 2003-2004 was 61.8 per 1000 Medicare beneficiary person-years. The rate was significantly higher for females and for those aged 75-84 years. After adjustment for age and sex, blacks had approximately a 30% lower rate of surgery than whites. While only 5% of cataract surgeons performed more than 500 cataract surgeries annually, these surgeons performed 26% of the total cataract surgeries. Increasing surgical volume was found to be highly correlated with use of ambulatory surgical centers and reduced time interval between first- and second-eye surgery in the same patient. The epidemiology of cataract surgery in the United States Medicare population documents substantial variation in surgical rates by race, sex, age, and by certain provider characteristics.

  10. Connexin mutants and cataracts

    Directory of Open Access Journals (Sweden)

    Eric C Beyer

    2013-04-01

    Full Text Available The lens is a multicellular, but avascular tissue that must stay transparent to allow normal transmission of light and focusing of it on the retina. Damage to lens cells and/or proteins can cause cataracts, opacities that disrupt these processes. The normal survival of the lens is facilitated by an extensive network of gap junctions formed predominantly of connexin46 and connexin50. Mutations of the genes that encode these connexins (GJA3 and GJA8 have been identified and linked to inheritance of cataracts in human families and mouse lines. In vitro expression studies of several of these mutants have shown that they exhibit abnormalities that may lead to disease. Many of the mutants reduce or modify intercellular communication due to channel alterations (including loss of function or altered gating or due to impaired cellular trafficking which reduces the number of gap junction channels within the plasma membrane. However, the abnormalities detected in studies of other mutants suggest that they cause cataracts through other mechanisms including gain of hemichannel function (leading to cell injury and death and formation of cytoplasmic accumulations (that may act as light scattering particles. These observations and the anticipated results of ongoing studies should elucidate the mechanisms of cataract development due to mutations of lens connexins and abnormalities of other lens proteins. They may also contribute to our understanding of the mechanisms of disease due to connexin mutations in other tissues.

MAIN OUTCOME MEASURES: The prevalence of post-surgical complications and secondary mucocele formation were compiled. RESULTS: Pathologies included osteoma (n = 34, 49%, mucocele (n = 27, 39%, fibrous dysplasia (n = 6, 9%, and encephalocele (n = 2, 3%. Complications included skin infections (n = 6, postoperative cutaneous fistula (n = 1, telecanthus (n = 4, diplopia (n = 3, nasal deformity (n = 2 and epiphora (n = 1. None of the patients suffered from postoperative CSF leak, meningitis or pneumocephalus. Six patients, all of whom had previously undergone frontal sinus obliteration, required revision surgery due to secondary mucocele formation. Statistical analysis using non-inferiority test reveal that cranialization of the frontal sinus is non-inferior to obliteration for preventing secondary mucocele formation (P<0.0001. CONCLUSION: Cranialization of the frontal sinus appears to be a good option for prevention of secondary mucocele development after open excision of benign frontal sinus lesions.

    Retrospective 5-year study based on general and ophthalmic history records, and including 268 eyes (174 patients), aged 50 years and over. Ophthalmological examination involved visual acuity, measuring of intraocular pressure, slit lamp examination and indirect ophthalmoscopy. Type of surgical treatment was tailored for each patient (extra capsular cataract extraction, phaco-emulsiphication). Preoperative slit lamp examination showed phacodonesis in 17.91% (47), iridodonesis in 2.98% (8), pigment dispersion in 6.72% (18), lens subluxation in 4.85% (13) on the total. Extra capsular cataract extraction was performed in 36.94% (99) and phaco-emulsiphication in the others. Analysis of intra operative complications showed: posterior capsular rupture 17.91% (48), zonular dialysis or break 5.97% (16), lens subluxation 1.86% (5), intraocular bleeding 2.98% (8), vitreous loss 13.80% (37). Postoperative complications include: anterior chamber reaction 45.90% (123), intraocular lens tilt 15.67% (42), endothelial decompensation 21.64% (58), subluxation/luxation IOL 3.73% (10), secondary cataract 21.46% (58), pigment dispersion 37.68% (101), increased IOP 13.80% (37), residual lens matter 13.80% (37), hyphema 3.73% (10), posterior synechiae 6.72% (18), iris prolapsus 2.73% (8). Cataract surgery in PES will frequently encounter small pupils, shallow anterior chambers, posterior adhesions, weak zonular support, partial subluxation or complete dislocation of lens. Authors presented the best possible approach on PES and surgical methods for patients with cataract with special accent of possible surgical complications.

    Full Text Available Abstract Background Coronary heart disease (CHD is a significant cause of health and economic burden. Secondary prevention programs play a pivotal role in the treatment and management of those affected by CHD although participation rates are poor due to patient, provider, health system and societal-level barriers. As such, there is a need to develop innovative secondary prevention programs to address the treatment gap. Telephone-delivered care is convenient, flexible and has been shown to improve behavioural and clinical outcomes following myocardial infarction (MI. This paper presents the design of a randomised controlled trial to evaluate the efficacy of a six-month telephone-delivered secondary prevention program for MI patients (ProActive Heart. Methods 550 adult MI patients have been recruited over a 14 month period (December 2007 to January 2009 through two Brisbane metropolitan hospitals, and randomised to an intervention or control group (n = 225 per group. The intervention commences within two weeks of hospital discharge delivered by study-trained health professionals ('health coaches' during up to 10 × 30 minute scripted telephone health coaching sessions. Participants also receive a ProActive Heart handbook and an educational resource to use during the health coaching sessions. The intervention focuses on appropriate modification of CHD risk factors, compliance with pharmacological management, and management of psychosocial issues. Data collection occurs at baseline or prior to commencement of the intervention (Time 1, six months follow-up or the completion of the intervention (Time 2, and at 12 months follow-up for longer term outcomes (Time 3. Primary outcome measures include quality of life (Short Form-36 and physical activity (Active Australia Survey. A cost-effective analysis of the costs and outcomes for patients in the intervention and control groups is being conducted from the perspective of health care costs to the

  18. HIV, other STD, and pregnancy prevention education in public secondary schools -- 45 states, 2008-2010.

    2012-04-06

    In the United States, 46% of high school students have had sexual intercourse and potentially are at risk for human immunodeficiency virus (HIV) infection, other sexually transmitted diseases (STDs), and pregnancy. The National HIV/AIDS Strategy for the United States recommends educating young persons about HIV before they begin engaging in behaviors that place them at risk for HIV infection. The Community Preventive Services Task Force (CPSTF) also recommends risk reduction interventions to prevent HIV, other STDs, and pregnancy among adolescents. To estimate changes in the percentage of secondary schools that teach specific HIV, other STD, and pregnancy risk reduction topics, a key intervention consistent with those supported by the National HIV/AIDS Strategy and CPSTF, CDC analyzed 2008 and 2010 School Health Profiles data for public secondary schools in 45 states. This report summarizes the results of those analyses, which indicated that in 2010, compared with 2008, the percentage of secondary schools teaching 11 topics on HIV, other STD, and pregnancy prevention in a required course in grades 6, 7, or 8 was significantly lower in 11 states and significantly higher in none; the percentage of secondary schools teaching eight topics in a required course in grades 9, 10, 11, or 12 was significantly lower in one state and significantly higher in two states; and the percentage of secondary schools teaching three condom-related topics in a required course in grades 9, 10, 11, or 12 was significantly lower in eight states and significantly higher in three states. Secondary schools can increase efforts to teach all age-appropriate HIV, other STD, and pregnancy prevention topics to help reduce risk behaviors among students.

    Full Text Available The aim of this study was to assess the level of availability of HIV prevention strategies in secondary schools in Kabarole district, Uganda in order to inform the design of interventions to strengthen HIV Prevention and psychosocial support. Quantitative and qualitative research methods were used in eight secondary schools in Kabarole district to establish available HIV prevention and psychosocial support services. Questionnaires were administered to 355 students 12-24 years old. In addition, 20 Key Informant interviews were held with education service providers. Quantitative data was analyzed using Epi-data and qualitative data were analyzed by thematic content analysis. Seven of the eight schools had at least one HIV prevention strategy. Two teachers in each of the five schools had been trained in HIV prevention. No school had a nurse trained in HIV prevention, care and support. Education service providers had limited knowledge of HIV prevention support and care of students living with HIV. We found out that students had knowledge on how one can acquire HIV. HIV prevention services reported by students in schools included: talks from teachers and guests (19%, drama with HIV prevention related messages (16%, peer education clubs (15%, workshops and seminars on HIV (8%, sensitization about HIV/AIDS (7%, guidance and counseling (6%, talking compounds- (5%, abstinence talks (6%, keeping students busy in sports (4%, straight talk (4%. Sixty three percent reported receiving HIV reading materials from various sources. Preventing HIV infection among students in schools is still demanding with limited interventions for students. Efforts to support school interventions should focus on including HIV Prevention in the school curriculum, working with peer educators as well as education service providers who spend much of the time with the students while at school.

  20. Optimising secondary prevention in the acute period following a TIA of ischaemic origin.

    Transient ischaemic attacks (TIAs) are highly prevalent conditions, with at least 46 000 people per year in the UK having a TIA for the first time. TIAs are a warning that the patient is at risk of further vascular events and the 90-day risk of vascular events following a TIA, excluding events within the first week after diagnosis when the risk is highest, can be as high as 18%. Immediate assessment of patients with TIA, either at accident and emergency, general practice and/or TIA clinics, is therefore required to address secondary prevention and prevent further vascular events. This article addresses the need for optimising secondary prevention in the acute period following a TIA of ischaemic origin to reduce the risk of further vascular events as per recent Cochrane review advice and presents a novel project, Stroke Prevention Rehabilitation Intervention Trial of Exercise (SPRITE), to do this. One novel way to tackle vascular risk factors and promote secondary prevention in patients with TIA could be to adapt a cardiac rehabilitation programme for these patients. SPRITE, a feasibility and pilot study (ClinicalTrials.gov Identifier: NCT02712385) funded by the National Institute for Health Research, is attempting to adapt a home-based cardiac rehabilitation programme, 'The Healthy Brain Rehabilitation Manual', for use in the acute period following a TIA. The use of cardiac rehabilitation programmes post-TIA requires further research, particularly within the primary care setting.

    2015-01-01

    The field of Alzheimer disease (AD) prevention has been a culmination of basic science, clinical, and translational research. In the past three years since the new 2011 AD diagnostic guidelines, large-scale collaborative efforts have embarked on new clinical trials with the hope of someday preventing AD. This review will shed light on the historical and scientific contexts in which these trials were based on, as well as discuss potential challenges these trials may face in the coming years. Primary preventive measures, such as lifestyle, multidomain, medication, and supplemental interventions, will be analyzed. Secondary prevention as represented by disease-modifying interventions, such as anti-amyloid therapy and pioglitazone, will also be reviewed. Finally, hypotheses on future directions for AD prevention trials will be proposed. PMID:27697063

    Full Text Available Pur po se: To evaluate the long-term visual outcome and to determine the surgical complications after cataract surgery in patients with unilateral childhood cataract. Ma te ri al and Met hod: We retrospectively reviewed the records of 18 cases with unilateral childhood cataract who had undergone cataract surgery before the age of seven. Primary intraocular lens (IOL implantation was made in children who were older than 1 year of age. Secondary IOL implantation was made after 18 months in children who were operated before the age of 1 year and were left aphakic. Occlusion therapy was performed to all children for amblyopia postoperatively. Visual acuity and complications were evaluated in a mean follow-up period of 4.8 years. Re sults: The mean age of the 18 patients (9 female/9 male at the time of surgery was 43.6±33.7(1-84 months. Eleven (61% patients had cataract surgery after 1 year of age. Secondary IOL implantation was performed at mean 28th month in 4 of 7 aphakic patients (57% who had cataract surgery before one year of age. In 3 (43% aphakic patients, secondary IOL implantation could not be performed because of ocular pathologies such as microophthalmia. Final visual acuity was 0.5 or better in 7 eyes (39%, between 0.1 and 0.5 in 6 eyes (33%, and worse than 0.1 - in 5 eyes (28%. Of 5 eyes that had visual acuity worse than 0.1, 4 (80% had at least one additional ocular pathology such as microphthalmia, strabismus and nystagmus. Nd:YAG laser posterior capsulotomy was performed at mean 8th month in 7 of 8 (87% children whose posterior capsules were left intact at surgery. Dis cus si on: Favorable visual outcomes can be achieved with surgical intervention and complementary amblyopia treatment in children with unilateral cataract. Preoperative microphthalmia, nystagmus and strabismus are not entirely an obstacle to visual development, but they are important factors leading to low visual acuity.

    Full Text Available Purpose: To evaluate the outcome of phacoemulsification in eyes with subluxated cataract. Materials and Methods: This retrospective study comprised 22 eyes of 20 consecutive patients with subluxated cataracts of varying aetiology operated between March 1998 and March 2001. Detailed preoperative assessment included visual acuity (VA, slitlamp examination, presence of vitreous in anterior chamber, extent of subluxation, intraocular pressure (IOP and detailed fundus examination. Phacoemulsification was done to retain the natural bag support and all patients had acrylic foldable Acrysof IOL implantation either in-the-bag or by scleral fixation. Postoperative observations included best-corrected visual acuity (BCVA, IOP, pupillary reaction and the IOL position. Results: The aetiology of the subluxation was traumatic in 11 patients and non-traumatic in 9 patients. Fifteen were males and 5 were females. Mean follow-up was 11.7 ± 9.71 months (range 4-39. The average age was 39.15 ± 16.33 (range 5 - 74. A 2-port anterior chamber vitrectomy was performed in 6 eyes (27.2%. Capsule tension ring (CTR was implanted in 15 eyes (68.18%.

    Extracapsular cataract extraction and intraocular lens implantation was performed on 4 eyes of 3 patients with radiation cataract. Case 1 was a 60-year-old man who was exposed to the ionizing radiation of the atomic bomb in Hiroshima 730 meters from the center of the explosion. He developed atomic bomb radiation senile cataracts in both eyes. Despite cataract surgery, a central plaque remained on the posterior capsule in the region corresponding to the central dense opacity in both eyes. Case 2 was an 81-year-old man who was in a streetcar 1,000 meters from the center of the explosion at the time of the atomic bombing. Senile and radiation-induced cataract decreased the visual acuity in both eyes. After extracapsular cataract extraction in his right eye, central opacification and a fibrous white membrane remained on the posterior capsule. These were removed by Nd-YAG laser capsulotomy six days after surgery. Case 3 was a 56-year-old man who developed radiation cataract after radiation therapy to a malignant lymphoma in the right orbit. Phacoemulsification and aspiration could not remove the fibrous white membrane from the posterior capsule in this case. Central opacities and fibrous white membranes on the posterior capsule after cataract surgery appears to be a characteristic of radiation cataract. (author)

    This study evaluates the effects of a 3-year smoking prevention programme in secondary schools in Helsinki. The study is part of the European Smoking prevention Framework Approach (ESFA), in which Denmark, Finland, the Netherlands, Portugal, Spain and the UK participated. A total of 27 secondary schools in Finland participated in the programme (n = 1821). Schools were randomised into experimental (13) and control groups (14). The programme included 14 information lessons about smoking and refusal skills training. The 3-year smoking prevention programme was also integrated into the standard curriculum. The community-element of the programme included parents, parish confirmation camps and dentists. The schools in the experimental group received the prevention programme and the schools in the control group received the standard health education curriculum. Among baseline never smokers (60.8%), the programme had a significant effect on the onset of weekly smoking in the experimental group [OR = 0.63 (0.45-0.90) P = 0.009] when compared with the control group. Being female, doing poorly at school, having parents and best friends who smoke and more pocket money to spend compared with others were associated with an increased likelihood of daily and weekly smoking onset. These predictors did not have an interaction effect with the experimental condition. This study shows that a school- and community-based smoking prevention programme can prevent smoking onset among adolescents.

    Sexuality plays a very significant role in the lives of both boys and girls. It is, therefore, considered important for schools to recognise and accept sexuality as part of the development process of the child. Professor Kader Asmal (previous South African Minister of Education) suggested that the earlier the school begins to teach learners about sexuality, the better because they can be easily misled by their peers if proper guidance regarding their sexuality is not given. The current study was conducted to assess the awareness of teenagers on the prevention of teenage pregnancy (TP) in six secondary school learners situated in the Soutpansberg-West circuit, Makhado Municipality in Limpopo province. The study was conducted at six secondary schools situated in the Soutpansberg-West circuit, Makhado Municipality in Limpopo province in 2014. A quantitative descriptive survey study was conducted where data were collected, using self-administered questionnaires, from 381 systematically sampled participants from six secondary schools situated in the Soutpansberg-West circuit, Makhado Municipality in Limpopo province. Data were analysed descriptively using the Statistical Package for the Social Sciences (SPSS) software, version 22.0. Necessary approval procedures and ethical clearance were obtained prior to data collection. Ninety-four percent of participants agreed that TP can be prevented through abstaining from sex, whilst 65% of participants agreed that TP could be prevented by using contraceptives such as pills and injections. Eighty-three percent of participants agreed that T Pcould be prevented through the use of condoms. Seventy-four percent participants disagreed that bathing after sex prevents teenage pregnancies. Furthermore, 28% participants agreed that TP can be prevented by oral sex. The conclusion drawn was that learners are aware of the measures for preventing TP.

    Full Text Available Effective methods of secondary prevention after stroke or TIA are available but adherence to recommended evidence-based treatments is often poor. The study aimed to determine the quality of secondary prevention in usual care and to develop a stepwise modeled support program.Two consecutive cohorts of patients with acute minor stroke or TIA undergoing usual outpatient care versus a secondary prevention program were compared. Risk factor control and medication adherence were assessed in 6-month follow-ups (6M-FU. Usual care consisted of detailed information concerning vascular risk factor targets given at discharge and regular outpatient care by primary care physicians. The stepwise modeled support program additionally employed up to four outpatient appointments. A combination of educational and behavioral strategies was employed.168 patients in the observational cohort who stated their openness to participate in a prevention program (mean age 64.7 y, admission blood pressure (BP: 155/84 mmHg and 173 patients participating in the support program (mean age 67.6 y, BP: 161/84 mmHg were assessed at 6 months. Proportions of patients with BP according to guidelines were 50% in usual-care and 77% in the support program (p<0.01. LDL<100 mg/dl was measured in 62 versus 71% (p = 0.12. Proportions of patients who stopped smoking were 50 versus 79% (p<0.01. 72 versus 89% of patients with atrial fibrillation were on oral anticoagulation (p = 0.09.Risk factor control remains unsatisfactory in usual care. Targets of secondary prevention were met more often within the supported cohort. Effects on (cerebro-vascular recurrence rates are going to be assessed in a multicenter randomized trial.

    Dose assessments for cataract threshold doses are available based on epidemiological studies of radiotherapy patients, survivors of the nuclear bombing of Hiroshima and Nagasaki, and of persons with occupational exposure to radiation. According to these, short-term application of low-level LET radiation of a dose ranging between 0.5 and 2.0 Gy may suffice to cause a cataract in the course of a few months or years which results in inpairment of vision (UNSCEAR, 1982). In fractionated irradiation, cataractogenic threshold dose increases to 4 Sv at treatment times between 3 weeks and 3 months, and to more than 5 Sv at more than 3 months (ICRP 41). Densely ionizing radiation must be assumed to have threshold doses between 2 and 20 Sv. An ICRP assessment (ICRP Publ. No. 41, 1984) gives a threshold dose of more than 8 Sv for a vision-impairing cataract if these was protracted irradiation at a low-level dose rate. Concerning radiation protection, a maximum lens dose of 150 mSv per annum was recommended which should not be exceeded. This indicates a maximum of 7.5 Sv of exposure throughout a period of 50 years of working life. (orig./HP) [de

    Examination of the results and describing the technique of manual small incision extracapsular cataract extraction on patients with advanced cataracts in urban Australia. A descriptive case series. Thirty-eight patients at three public hospitals, one tertiary and two secondary ophthalmic units in urban Australia. Forty eyes with dense mature cataracts with hand movement vision or worse underwent a planned manual small incision extracapsular cataract extraction instead of traditional phaco-emulsification. Postoperative visual aquity, surgically induced astigmatism and complications. Seventy-eight per cent of patients had an uncorrected visual acuity of 6/12 or better on the first postoperative day. Eighty-three per cent of patients had a distance corrected visual acuity of 6/9 or better 3 months postoperatively. One case was complicated by a posterior capsule rupture. No cases of endophthalmitis were reported. The summated vector mean of the surgically induced astigmatism was 0.089D at 93°. Manual small incision extracapsular cataract extraction is an efficacious cataract surgery technique with good visual outcome and is a safe alternative to phaco-emulsification in suitable cases in a first-world setting. © 2014 Royal Australian and New Zealand College of Ophthalmologists.

    To explore the cataract surgical rate (CSR) of Shanghai from 2006 to 2012 and examine its influencing factors. As of 2003, a cataract surgery registration form had been filled by physicians after every cataract surgery in Shanghai. The local eye disease prevention team then entered the relevant information into the Shanghai Cataract Operations Database. Based upon this database, CSR of Shanghai was calculated. And the number of cataract surgeries was compared between Shanghai urban and suburban districts as well as among different medical institutions. The overall CSR in Shanghai increased from 1741 in 2006 to 2313 in 2012. In 2012, CSR in urban districts reached 6013 while it stood at 460 and 584 in inner and outer suburb districts respectively. The number of hospitals performing cataract surgery in urban districts was much more than that in suburbs. And the average number of cataract surgeries per hospital per year in suburbs was only one third of that (748 cases) in urban areas. The number of cataract surgeries at in private hospitals increased rapidly during the past 7 years. The number of 1921 cases was nearly twice as many as that at tertiary hospitals in 2012. Phacoemulsification surgery was the most popular surgical choice for cataract removal, accounting for 98.40% of total cataract surgeries in 2012. Until 2012, CSR in Shanghai dropped below the target of World Health Organization (WHO). A low level of CSR in suburbs is a major influencing factor for the overall level of CSR in Shanghai.

    Full Text Available Amblyopia should always be anticipated in children with unilateral cataract, asymmetrical bilateral cataracts (or where there is a delay between the first and second eye operation, or a delay of more than a year between diagnosis/ detection and surgery, cataracts with anisometropia or traumatic cataracts with corneal scars. When amblyopia is detected, occlusion therapy (eye patching must be instituted at the earliest opportunity. The patching regimen is the same with any strabismic amblyopia and sometimes needs to be aggressive at the start. It is crucial to explain the need for patching to the parents, since compliance is the greatest obstacle to the success of amblyopia treatment.

    The aim of this paper is to underline the importance of the role of general practitioners (GPs) in distributing vital information about prevention to citizens, to highlight the importance of the so-called voluntary prevention programmes, both for conditions for which no organised screening programmes exist and for those for which they do exist but may well be obsolete or inefficient. Nowadays, voluntary prevention is made more effective thanks to the new sophisticated diagnostic technologies applied worldwide by diagnostic imaging. Epidemiological data about the incidence and causes of death among the Italian population have shown that screening programmes should be aimed first at fighting the following diseases: prostatic carcinoma, lung cancer, colorectal carcinoma, breast cancer, cardiovascular disease, cerebrovascular disease, aortic and peripheral vascular disease. GPs do not generally give good or adequate instructions concerning voluntary prevention programmes; GPs may not even be aware of this type of prevention which could represent a valuable option together with the existing mass screening programmes. Therefore, in the following analysis, we aim to outline the correct diagnostic pathway for the prevention of diseases having the highest incidence in our country and which represent the most frequent causes of death. If used correctly, these screening programmes may contribute to the success of secondary prevention, limiting the use of tertiary prevention and thus producing savings for the Italian National Health System.

    Cataract and glaucoma are leading causes of blindness worldwide, and their co-existence is common in elderly people. Glaucoma surgery can accelerate cataract progression, and performing both surgeries may increase the rate of postoperative complications and compromise the success of either surgery. However, cataract surgery may independently lower intraocular pressure (IOP), which may allow for greater IOP control among patients with co-existing cataract and glaucoma. The decision between undergoing combined glaucoma and cataract surgery versus cataract surgery alone is complex. Therefore, it is important to compare the effectiveness of these two interventions to aid clinicians and patients in choosing the better treatment approach. To assess the relative effectiveness and safety of combined surgery versus cataract surgery (phacoemulsification) alone for co-existing cataract and glaucoma. The secondary objectives include cost analyses for different surgical techniques for co-existing cataract and glaucoma. We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (2014, Issue 10), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE (January 1946 to October 2014), EMBASE (January 1980 to October 2014), PubMed (January 1948 to October 2014), Latin American and Caribbean Health Sciences Literature Database (LILACS) (January 1982 to October 2014), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com), ClinicalTrials.gov (www.clinicaltrials.gov), and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en).

    An accurate assessment of the cardiovascular (CV) risk of an individual is key for guiding the appropriate treatment strategy for cardiovascular disease (CVD). Although conventional risk factors for CVD are well established, there can be substantial variation in the extent of atherosclerosis between patients. The use of a variety of imaging modalities can be beneficial in the primary prevention stage and in the classification of an individual's CV risk. Therefore, appropriate implementation of these imaging techniques for risk assessment purposes, in line with clinical guidelines, can influence the outcomes of CVD prevention. The expert working group collaborated to review current invasive and non-invasive imaging techniques available to healthcare practitioners and how they can be used in the measurement of preclinical vascular damage and CV risk assessment. After evaluation of the current guideline recommendations and clinical data available, the expert working group collaborated to produce recommendations regarding the use of imaging in the risk stratification in primary prevention, CV risk in peri-acute coronary syndrome and CV risk assessment in secondary prevention. Overall, a variety of both invasive and non-invasive imaging modalities were highlighted by the expert working group as having the potential to assist in the risk assessments of patients at risk of CVD. These imaging techniques can be utilised in both primary and secondary prevention strategies and have the potential to be important risk modifiers, improving the outcome of CV risk assessment.

    A century after its discovery, Chagas' disease still represents a major public health challenge in Latin America. Moreover, because of growing population movements, an increasing number of cases of imported Chagas' disease have now been detected in non-endemic areas, such as North America and some European countries. This parasitic zoonosis, caused by Trypanosoma cruzi, is transmitted to humans by infected Triatominae insects, or occasionally by non-vectorial mechanisms, such as blood transfusion, mother to fetus, or oral ingestion of materials contaminated with parasites. Following the acute phase of the infection, untreated individuals enter a chronic phase that is initially asymptomatic or clinically unapparent. Usually, a few decades later, 40-50% of patients develop progressive cardiomyopathy and/or motility disturbances of the oesophagus and colon. In the last decades several interventions targeting primary, secondary and tertiary prevention of Chagas' disease have been attempted. While control of both vectorial and blood transfusion transmission of T cruzi (primary prevention) has been successful in many regions of Latin America, early detection and aetiological treatment of asymptomatic subjects with Chagas' disease (secondary prevention) have been largely underutilised. At the same time, in patients with established chronic disease, several pharmacological and non-pharmacological interventions are currently available and have been increasingly used with the intention of preventing or delaying complications of the disease (tertiary prevention). In this review we discuss in detail each of these issues.

    In the last years prevention of temporomandiboular joint (TMJ) disease had acquired great importance. According to the neuro-occlusal rehabilitation (RNO) it is possible to say that TMJ disease starts since first years of life. So it is important both for dentist and for pediatric know what are the conditions and the atypical functions which predispose to this pathology. The aim of this work was to show how it is possible to intercept since primary teeth and the correct norms of primary and secondary prevention.

  20. Comparing primary prevention with secondary prevention to explain decreasing coronary heart disease death rates in Ireland, 1985-2000.

    BACKGROUND: To investigate whether primary prevention might be more favourable than secondary prevention (risk factor reduction in patients with coronary heart disease(CHD)). METHODS: The cell-based IMPACT CHD mortality model was used to integrate data for Ireland describing CHD patient numbers, uptake of specific treatments, trends in major cardiovascular risk factors, and the mortality benefits of these specific risk factor changes in CHD patients and in healthy people without recognised CHD. RESULTS: Between 1985 and 2000, approximately 2,530 fewer deaths were attributable to reductions in the three major risk factors in Ireland. Overall smoking prevalence declined by 14% between 1985 and 2000, resulting in about 685 fewer deaths (minimum estimate 330, maximum estimate 1,285) attributable to smoking cessation: about 275 in healthy people and 410 in known CHD patients. Population total cholesterol concentrations fell by 4.6%, resulting in approximately 1,300 (minimum estimate 1,115, maximum estimate 1,660) fewer deaths attributable to dietary changes(1,185 in healthy people and 115 in CHD patients) plus 305 fewer deaths attributable to statin treatment (45 in people without CHD and 260 in CHD patients). Mean population diastolic blood pressure fell by 7.2%, resulting in approximately 170 (minimum estimate 105, maximum estimate 300) fewer deaths attributable to secular falls in blood pressure (140 in healthy people and 30 in CHD patients), plus approximately 70 fewer deaths attributable to antihypertensive treatments in people without CHD. Of all the deaths attributable to risk factor falls, some 1,715 (68%) occurred in people without recognized CHD and 815(32%) in CHD patients. CONCLUSION: Compared with secondary prevention, primary prevention achieved a two-fold larger reduction in CHD deaths. Future national CHD policies should therefore prioritize nationwide interventions to promote healthy diets and reduce smoking.

    Routinely fasting is not necessary for measuring the lipid profile according to the latest European consensus. However, LDL-C tends to be lower in the non-fasting state with risk of misclassification. The extent of misclassification in secondary cardiovascular prevention with a non-fasting lipid profile was investigated. 329 patients on lipid lowering therapy for secondary cardiovascular prevention measured a fasting and non-fasting lipid profile. Cut-off values for LDL-C, non-HDL-C and apolipoprotein B were set at fasting LDL-C (calculated using the Friedewald formula), direct LDL-C, non-HDL-C and apolipoprotein B. Net misclassification fasting measurements resulted in lower LDL-C (-0.2±0.4mmol/l, Pfasting LDL-C target of fasting state. In the non-fasting state net misclassification with direct LDL-C was 5.7% (95% CI 2.1-9.2%), 4.0% (95% CI 1.0-7.4%) with non-HDL-C and 4.1% (95% CI 1.1-9.1%) with apolipoprotein B. Use of non-fasting LDL-C as treatment target in secondary cardiovascular prevention resulted in significant misclassification with subsequent risk of undertreatment, whereas non-fasting direct LDL-C, non-HDL-C and apolipoprotein B are reliable parameters.

    BACKGROUND: Secondary prevention pharmacotherapy in post-myocardial infarction (MI) patients reduces the risk of subsequent coronary events and overall mortality. International guidelines recommend use of aspirin, beta-blockers, ACE inhibitors and statins in post-MI patients. AIMS: We performed this audit to review the compliance of prescribing practices, in a regional hospital in Ireland, with international guidelines for secondary prevention of coronary artery disease. METHODS: We performed a retrospective case review of 172 patients diagnosed with MI during a 1-year period between January and December 2007. RESULTS: A total of 134 patients fulfilled the inclusion criteria. On discharge, aspirin was prescribed to 131 (97.76%) patients, clopidogrel to 126 (94%), beta-blockers to 117 (87%), ACE inhibitor to 87 (65%), ARB to 10 (7%) and statins to 116 (87%). CONCLUSION: Our audit shows that targets for prescription of secondary prevention medications were not met in a small but significant proportion of patients and calls for review of discharge practices and education to improve compliance with guidelines.

    To determine the cost-effectiveness of lipid-lowering therapy in the secondary prevention of cardiovascular events in the Philippines. A cost-utility analysis was performed by using Markov modeling in the secondary prevention setting. The models incorporated efficacy of lipid-lowering therapy demonstrated in randomized controlled trials and mortality rates obtained from local life tables. Average and incremental cost-effectiveness ratios were obtained for simvastatin, atorvastatin, pravastatin, and gemfibrozil. The costs of the following were included: medications, laboratory examinations, consultation and related expenses, and production losses. The costs were expressed in current or nominal prices as of the first quarter of 2010 (Philippine peso). Utility was expressed in quality-adjusted life-years gained. Sensitivity analyses were performed by using variations in the cost centers, discount rates, starting age, and differences in utility weights for stroke. In the analysis using the lower-priced generic counterparts, therapy using 40 mg simvastatin daily was the most cost-effective option compared with the other therapies, while pravastatin 40 mg daily was the most cost-effective alternative if the higher-priced innovator drugs were used. In all sensitivity analyses, gemfibrozil was strongly dominated by the statins. In secondary prevention, simvastatin or pravastatin were the most cost-effective options compared with atorvastatin and gemfibrozil in the Philippines. Gemfibrozil was strongly dominated by the statins. Copyright © 2013 International Society for Pharmacoeconomics and Outcomes Research (ISPOR). Published by Elsevier Inc. All rights reserved.

    Directory of Open Access Journals (Sweden)

    Simon C Mathews

    Full Text Available BACKGROUND: Epidemiologic studies suggest that LDL particle concentration (LDL-P may remain elevated at guideline recommended LDL cholesterol goals, representing a source of residual risk. We examined the following seven separate lipid parameters in achieving the LDL-P goal of <1000 nmol/L goal for very high risk secondary prevention: total cholesterol to HDL cholesterol ratio, TC/HDL, <3; a composite of ATP-III very high risk targets, LDL-C<70 mg/dL, non-HDL-C<100 mg/dL and TG<150 mg/dL; a composite of standard secondary risk targets, LDL-C<100, non-HDL-C<130, TG<150; LDL phenotype; HDL-C ≥ 40; TG<150; and TG/HDL-C<3. METHODS: We measured ApoB, ApoAI, ultracentrifugation lipoprotein cholesterol and NMR lipoprotein particle concentration in 148 unselected primary and secondary prevention patients. RESULTS: TC/HDL-C<3 effectively discriminated subjects by LDL-P goal (F = 84.1, p<10(-6. The ATP-III very high risk composite target (LDL-C<70, nonHDL-C<100, TG<150 was also effective (F = 42.8, p<10(-5. However, the standard secondary prevention composite (LDL-C<100, non-HDL-C<130, TG<150 was also effective but yielded higher LDL-P than the very high risk composite (F = 42.0, p<10(-5 with upper 95% confidence interval of LDL-P less than 1000 nmol/L. TG<150 and TG/HDL-C<3 cutpoints both significantly discriminated subjects but the LDL-P upper 95% confidence intervals fell above goal of 1000 nmol/L (F = 15.8, p = 0.0001 and F = 9.7, p = 0.002 respectively. LDL density phenotype neared significance (F = 2.85, p = 0.094 and the HDL-C cutpoint of 40 mg/dL did not discriminate (F = 0.53, p = 0.47 alone or add discriminatory power to ATP-III targets. CONCLUSIONS: A simple composite of ATP-III very high risk lipoprotein cholesterol based treatment targets or TC/HDL-C ratio <3 most effectively identified subjects meeting the secondary prevention target level of LDL-P<1000 nmol/L, providing a potential alternative to advanced lipid testing in many clinical

    Glaucoma is the third-most-frequent cause of blindness in the world, with a total of 5.2 million blind people as a result of this disease; 80% live in developing countries. In Paraguay, after cataract it is the second-most-frequent-cause. Early detection of the risk factors and groups can help to avoid progress of this disease. Trauma, cataract and infectious uveitis represent special risks for developing secondary glaucoma, which is a more frequent cause of blindness in third-world countries than in industrialized nations. Until now there has been little data regarding the causes, disease course, and options for therapy. Therefore, secondary glaucoma was examined in Paraguay to obtain information on the situation in Latin America. The aim of the study was to explore the causes of secondary glaucoma for programs concerning prevention and therapy. From November 1996 to February 1997 patients with secondary glaucoma were examined at the University Hospital of Asunción, Paraguay. After the clinical examination the secondary glaucomas were classified. Patients with primary glaucoma were included in the same period of time as well in order to get the rate of secondary glaucoma. Altogether 293 patients were examined: 61 with secondary and 232 with primary glaucoma. The causes of secondary glaucoma in 73 eyes were: 20 (27%) with pseudoexfoliation glaucoma, 19 (26%) with post-traumatic glaucoma, 16 (22%) with neovascular glaucoma, 4 (5%) with lens-related glaucoma, 3 (4%) with glaucoma associated with ocular surgery, 2 (3%) with pigmentary and 2 (3%) with corticoid-induced glaucoma. A ratio of 4:1 primary glaucomas to secondary glaucomas was found. The development of special measures for prevention and early therapy is only possible if the causes of this severe disease are explored. The results of this study represent basic information and could help to introduce of prevention programs.

    To explore the association between health literacy and the risk of cardiovascular disease (CVD), and to assess the differential effects by health literacy level of a nurse-coordinated secondary prevention program (NCPP) in patients with coronary artery disease (CAD). Data were collected in two medical centres participating in the RESPONSE trial (Randomised Evaluation of Secondary Prevention by Outpatient Nurse SpEcialists). CVD risk profiles were assessed at baseline and 12-month follow-up using the Systematic Coronary Risk Evaluation (SCORE). Health literacy was assessed by the short Rapid Estimate of Adult Literacy in Medicine (REALM-D) and the Newest Vital Sign (NVS-D); self-reported health literacy was evaluated by the Set of Brief Screening Questions (SBSQ-D). Among 201 CAD patients, 18% exhibited reading difficulties, 52% had difficulty understanding and applying written information, and 5% scored low on self-reported health literacy. Patients with low NVS-D scores had a higher CVD risk [mean SCORE 5.2 (SD 4.8) versus 3.3 (SD 4.1), p literacy levels without significant differences. Inadequate health literacy is prevalent in CAD patients in the Netherlands, and is associated with less favourable CVD risk profiles. Where many other forms of CVD prevention fail, nurse-coordinated care seems to be effective among patients with inadequate health literacy.

    Since non-vitamin K antagonist oral anticoagulants (NOACs) were released for clinical use, many studies have investigated its effectiveness in stroke prevention. In this study, to determine whether or not there is a difference in outcome in secondary stroke prevention between warfarin and NOACs, patients with embolic stroke with newly prescribed anticoagulants were prospectively analyzed. Patients with acute ischemic stroke, who newly started anticoagulant therapy, were consecutively asked to participate in this study. Enrolled patients (76.3 ± 11.0 years old) were classified into warfarin (n = 48), dabigatran (n = 73), rivaroxaban (n = 49), and apixaban (n = 65). The outcome in 1 year was prospectively investigated at outpatient clinic or telephone interview. Recurrence of stroke and death was considered as the critical incidence. The prevalence of risk factors was not different among all medicines. Patients with dabigatran showed significantly younger onset age (P incident rates were 7.1%, 15.3%, 19.0%, and 29.7% for dabigatran, apixaban, rivaroxaban, and warfarin, respectively. Dabigatran showed relatively better outcome compared with warfarin (P = .069) and rivaroxaban (P = .055). All patients on NOACs presented lower cumulative stroke recurrence compared with warfarin. Even in the situation of secondary stroke prevention, noninferiority of NOACs to warfarin might be demonstrated. Copyright © 2018 National Stroke Association. Published by Elsevier Inc.

    Objectives This study assesses practice variation of secondary prevention medication prescription among coronary artery disease (CAD) patients treated in outpatient practices participating in the NCDR® PINNACLE Registry®. Background Among patients with CAD, secondary prevention with a combination of beta-blockers, angiotensin converting enzyme inhibitors/angiotensin receptor blockers, and statins reduces cardiac mortality and myocardial infarction (MI). Accordingly, every CAD patient should receive the combination of these medications for which they are eligible. However, little is known about current prescription patterns of these medications and the variation in use among outpatient cardiology clinics. Methods Using data from NCDR® PINNACLE Registry®, a national outpatient cardiology practice registry, we assessed medication prescription patterns among eligible CAD patients between July 2008 and December 2010. Overall rates of prescription and variation by practice were calculated, adjusting for patient characteristics. Results Among 156,145 CAD patients in 58 practices, 103,830 (66.5%) were prescribed the optimal combination of medications for which they were eligible. The median rate of optimal combined prescription by practice was 73.5% and varied from 28.8% to 100%. After adjustment for patient factors, the practice median rate ratio for prescription was 1.25 (95% CI 1.2,1.32), indicating a 25% likelihood that 2 random practices would differ in treating identical CAD patients. Conclusions Among a national registry of CAD patients treated in outpatient cardiology practices, over one-third of patients failed to receive their optimal combination of secondary prevention medications. Significant variation was observed across practices, even after adjusting for patient characteristics, suggesting that quality improvement efforts may be needed to support more uniform practice.

    Full Text Available Natural eye lens is a crystalline substance to produce a clear passage for light. Cataract is opacity within the clear lens of the eye and is the dominant cause of socio-medical problem i.e., blindness worldwide. The only available treatment of cataract is surgery. However, insufficient surgical facilities in poor and developing countries and post-operative complications inspire researchers to find out other modes of treatment for cataract. In this review, an attempt has been made to appraise various etiological factors of cataract to make their perception clear to build up counterpart treatment. Present study is an assortment of various available literatures and electronic information in view of cataract etiopathogenesis. Various risk factors have been identified in development of cataracts. They can be classified in to genetic factors, ageing (systemic diseases, nutritional and trace metals deficiencies, smoking, oxidative stress etc., traumatic, complicated (inflammatory and degenerative diseases of eye, metabolic (diabetes, galactosemia etc., toxic substances including drugs abuses, alcohol etc., radiation (ultraviolet, electromagnetic waves etc. are implicated as significant risk factors in the development of cataract.

    Full Text Available Background: The ischaemic stroke (IS is one of the most frequent cause of death in Germany. Besides of non-drug many drug-based interventions are used in primary or secondary prevention of IS, among them the thrombocyte aggregation inhibitors (TAI. Objectives: The evaluation addresses the questions on medical efficacy and cost-effectiveness of the TAI administration in the prevention of IS as compared to the management of risk factors alone as well as to the use of anticoagulant drugs. Methods: The literature search for articles published after 1997 was conducted in December 2003 in the most important medical and economic databases. The medical analysis was performed on the basis of the most up-to date meta-analyses of randomised controlled trials (RCT as well as of new published RCT. The data from the studies for stroke, bleeding complications as well as for the combined endpoint "severe vascular events" (SVE: death or stroke or myocardial infarction were summarised in meta-analyses.In order to include grey literature contact has been taken up with the pharmaceutical manufacturers of TAI. Results are presented in a descriptive way. Results: The medical analysis included data from 184 RCT (vs. placebo and from 22 RCT (vs. anticoagulant drugs. The absolute reduction of IS (4.8% vs. 6.6%; p<0,00001 and SVE (10.0% vs. 12.4%; p<0,00001 were definitely higher than the absolute increase of bleeding complications (1.6% vs. 0.9%; p<0,00001, but relatively similar to this absolute increase in a subpopulation with a low risk for SVE. With regard to the stroke prevention, evidence of efficacy could be yielded for acetylsalicil acid (ASA, dipyridamole, cilostazol, ridogrel and the combination ASA with dipyridamole. ASA is less effective than anticoagulants in the prevention of ischaemic stroke in atrial fibrillation, however, it causes fewer bleeding complications.Low dosed ASA can be considered cost-effective in secondary prevention of ischemic stroke

    2011-08-01

    Full Text Available There is consensus on clinical guidelines that beta-blockers (BB provide unquestionable benefits in several environments of secondary prevention, such as heart failure and myocardial infarction. However, in everyday practice they are underused in contexts where they are not contraindicated. Such is the case of heart failure with ejection fraction. This article presents an analysis on the available evidence of beta blockers’ effectiveness in heart failure with ejection fraction. It is concluded that overwhelming evidence favours the use of beta-blockers in chronic heart failure with ejection fraction, whereas in episodes of acute decompensated heart failure, their suspension should be avoided whenever it is possible.

    People with stroke or transient ischaemic attack (TIA) are at increased risk of future stroke and other cardiovascular events. Evidence-based strategies for secondary stroke prevention have been established. However, the implementation of prevention strategies could be improved. To assess the effects of stroke service interventions for implementing secondary stroke prevention strategies on modifiable risk factor control, including patient adherence to prescribed medications, and the occurrence of secondary cardiovascular events. We searched the Cochrane Stroke Group Trials Register (April 2013), the Cochrane Effective Practice and Organisation of Care Group Trials Register (April 2013), CENTRAL (The Cochrane Library 2013, issue 3), MEDLINE (1950 to April 2013), EMBASE (1981 to April 2013) and 10 additional databases. We located further studies by searching reference lists of articles and contacting authors of included studies. We included randomised controlled trials (RCTs) that evaluated the effects of organisational or educational and behavioural interventions (compared with usual care) on modifiable risk factor control for secondary stroke prevention. Two review authors selected studies for inclusion and independently extracted data. One review author assessed the risk of bias for the included studies. We sought missing data from trialists. This review included 26 studies involving 8021 participants. Overall the studies were of reasonable quality, but one study was considered at high risk of bias. Fifteen studies evaluated predominantly organisational interventions and 11 studies evaluated educational and behavioural interventions for patients. Results were pooled where appropriate, although some clinical and methodological heterogeneity was present. The estimated effects of organisational interventions were compatible with improvements and no differences in the modifiable risk factors mean systolic blood pressure (mean difference (MD) -2.57 mmHg; 95% confidence

    Full Text Available Clostridium difficile infections are a global clinical concern and are one of the leading causes of nosocomial outbreaks. Preventing these infections has benefited from multidisciplinary infection control strategies and new antibiotics, but the problem persists. Probiotics are effective in preventing antibiotic-associated diarrhea and may also be a beneficial strategy for C. difficile infections, but randomized controlled trials are scarce. This meta-analysis pools 21 randomized, controlled trials for primary prevention of C. difficile infections (CDI and four trials for secondary prevention of C. difficile recurrences and assesses the efficacy of specific probiotic strains. Four probiotics significantly improved primary CDI prevention: (Saccharomyces boulardii, Lactobacillus casei DN114001, a mixture of L. acidophilus and Bifidobacterium bifidum, and a mixture of L. acidophilus, L. casei and L. rhamnosus. None of the tested probiotics significantly improved secondary prevention of CDI. More confirmatory randomized trials are needed to establish if probiotics are useful for preventing C. difficile infections. v

    Full Text Available Background/Aim. Oxidative stress results from increased oxidative processes, decreased antioxidative protection, or both processes simultaneously. Photooxidative stress, as a form of oxidative stress, induced by the energy of solar radiation, today is considered as crucial in the age-related cataractogenesis. Other known and unknown, endogenous and egsogenous factors that contribute to the oxidative stress intensity, can influence the cataract type and brunescence. Thus the oxidative stress intensity and its form might determine the cataract type and brunescence, and also make the efforts in cataract prevention more complex. Hence, the objective of the present paper was to investigate the current amount of antioxidative capacity in aqueous humour during the cataract genesis of different types and pigmentation of cataract. Methods. Transversal review of 80 samples of humour aqueous obtained during extracapsular cataract extraction. Aqueouses were analyzed by tiobarbituric acid (TBA method for the total antioxidant activity estimation, expressed as %iMDA, and by using 0.1 ml of aqueous. Results. The mixed type of cataract showed the statistically significantly lower values of the intensities of antioxidative protection in aqueous humour compared to cortical and nuclear cataracts (p < 0.001, respectively. Between pure nuclear and cortical cataracts we found the small differences of the investigated parameter, but they pointed to the decreased level of antioxidative protection, i.e. the increased intensity of the aqueous humour oxidative stress in the cortical cataract type. A significant correlation between the cortical cataract maturation and the %iMDA (p < 0.05 was found. Conclusions. The role of the oxidative stress, here expressed as the antioxidative capacity of aqueous humour, could not be the same for all the cataract types. The lower level of antioxidative protection of aqueous in brunescent and mixed cataracts may point to the higher

    Full Text Available Congenital cataract is a leading cause of visual deprivation which can damage the developing visual system of a child; therefore early diagnosis, management and long-term follow-up are essential. It is recommended that all neonates be screened by red reflex examination at birth and suspected cases be referred to ophthalmic centers. Early surgery (1 year is highly recommended. After surgery, amblyopia treatment and periodic follow-up examinations should be started as soon as possible to achieve a satisfactory visual outcome. Practitioners should consider the possibility of posterior capsular opacity, elevated intraocular pressure and amblyopia during follow-up, especially in eyes with microphthalmia and/or associated congenital anomalies. All strabismic children should undergo slit lamp examination prior to strabismus surgery to rule out congenital lens opacities. From a social point of view, equal and fair medical care should be provided to all children regardless of gender.

    Post-traumatic stress disorder (PTSD) is unique amongst psychiatric disorders in two ways. Firstly, there is usually a very clear point of onset- the traumatic event The second unique feature of PTSD is that it is characterized by a failure of the normal response to resolve. Given these two characteristics, PTSD appears a good candidate for secondary prevention, ie, interventions immediately after the trauma. Evidence available starting from current concepts and contemporary research of potential secondary prevention interventions are presented. Common practices in the aftermath of trauma such as debriefing and benzodiazepines need to be carefully considered, taking into account their potential harm to the spontaneous recovery process, and the trajectory of PTSD, and not only judging them according to their immediate (comforting) effects. A discussion of the balance required between aiding recovery but not interfering with the potent natural resolution of symptoms (that is expected in most cases), along with potential avenues of future research, are presented. Results of a small pilot study with a single intervention of hydrocortisone immediately after trauma appear to be promising, and clearly indicate the need for further studies. PMID:22033784

    In hospital mortality of acute myocardial infarction (AMI) has been reduced due to the availability of better therapeutic strategies. But there is still a gap between mortality rates in randomised trials and daily clinical practice. Thus, it was aim of the present registry to document the course and outcome of patients with AMI and to improve patient care by implementing recent guidelines. In a nationwide registry study in hospitals in Germany with a cardiology unit or an internal medicine department data on consecutive patients were recorded for six to twelve months at admission, discharge and during a follow-up of one year. From 02/2003 until 10/2004 a total of 5,353 patients with acute myocardial infarction (65.7 % male, mean age of 67.6 +/- 17.7 years; 55.1 % of them with ST elevation myocardial infarction (STEMI) were included in the registry. Of the patients with STEMI, 76.6 % underwent acute intervention, 37.1 % had thrombolysis, 69.7 % percutaneous transluminal coronary angioplasty (PTCA). 40.0 % of those with non-Stemi (NSTEMI) had an acute intervention, 6.6 % thrombolysis, 73.5 % PTCA. Recommended secondary prevention consisted of ASS (93.2 %), beta-blockers (93.0 %), CSE-inhibitors (83.5 %), ACE-inhibitors (80.9 %) and clopidogrel (74.0 %). In-hospital mortality was 10.5 % (STEMI) and 7.4 % (NSTEMI). The 9 % mortality among patients with acute myocardial infarction treated in the hospitals participating in the SAMI registry is low compared to that in similar collectives. The high number of patients who had thrombofibrinolysis and coronary interventions as well as the early initiation of drug therapy contributed to these results. Medical treatment in the prehospital phase of these patients remains still insufficient and to a substantial extent contributes to the mortality of acute myocardial infarction.

    To review the previous year's literature related to prevalence of blindness in general, blindness due to cataract, cataract surgical coverage (CSC) and cataract surgical rates (CSRs). Cataracts are the major cause of blindness and visual impairment in developing countries and contributes to more than 90% of the total disability adjusted life years. This review shows that coverage continues to be a problem in many countries, especially for the female population, those residing in rural areas and those who are illiterate. Although CSR is an indicator of the availability and acceptability of services, for measuring the impact of the program, we should look at combining CSR with CSC. This strategy would also enable us achieve our goal of eliminating avoidable blindness due to cataracts by the year 2020. Cataracts still continue- to be a major cause of blindness globally and with the rapidly aging population, it is a challenge to tackle. We need to plan a comprehensive strategy addressing issues related to availability, affordability, accessibility and acceptability of eye-care services.

    The number of cataract surgeries performed globally will continue to rise to meet the needs of an aging population. This increased demand will require healthcare systems and providers to find new surgical efficiencies while maintaining excellent surgical outcomes. Immediately sequential bilateral cataract surgery (ISBCS) has been proposed as a solution and is increasingly being performed worldwide. The purpose of this review is to discuss the advantages and disadvantages of ISBCS. When appropriate patient selection occurs and guidelines are followed, ISBCS is comparable with delayed sequential bilateral cataract surgery in long-term patient satisfaction, visual acuity and complication rates. In addition, the risk of bilateral postoperative endophthalmitis and concerns of poorer refractive outcomes have not been supported by the literature. ISBCS is cost-effective for the patient, healthcare payors and society, but current reimbursement models in many countries create significant financial barriers for facilities and surgeons. As demand for cataract surgery rises worldwide, ISBCS will become increasingly important as an alternative to delayed sequential bilateral cataract surgery. Advantages include potentially decreased wait times for surgery, patient convenience and cost savings for healthcare payors. Although they are comparable in visual acuity and complication rates, hurdles that prevent wide adoption include liability concerns as ISBCS is not an established standard of care, economic constraints for facilities and surgeons and inability to fine-tune intraocular lens selection in the second eye. Given these considerations, an open discussion regarding the advantages and disadvantages of ISBCS is important for appropriate patient selection.

    Although elderly people has a higher incidence of coronary heart disease, this group is seldom included in clinical trials. Studies performed in Spain on elderly coronary heart disease patients have been conducted in hospital settings. The aim of our study was to analyse wether the management of coronary heart disease patients over 64 years of age cared by family physicians differed from that of the rest. Cross-sectional multicentre study embedded in a clinical trial on 1,022 patients with stable coronary heart disease in which socio-demographic variables, comorbidity, treatment and cardiovascular risk- factor control were collected. Mean age was 64 10, 74.0% were men and 53.8% of subjects were over 64 years. Patients over 64 years had a greater cardiovascular comorbidity (87.7 vs 82.6%; p = 0.002) and received lower number of drugs than the rest in the prevention of recurrences (60.4 vs 70.9%; p < 0.001). Probability to receive less than two drugs on secondary prevention by subjects over 64 years was 0.45 (95% CI, 0.30-0.68) despite comorbidity, sex and cardiovascular risk profile.Conclusions. Coronary heart disease patients over 64 years receive less drugs for coronary event recurrence prevention than their younger counterparts despite their worse cardiovascular risk profile.

    Whether vitamin C is a protective factor for age-related cataract remains unclear. Thus, we conducted a meta-analysis to summarize the evidence from epidemiological studies of vitamin C and the risk of age-related cataract. Pertinent studies were identified by searching in PubMed and in Webscience. The random effect model was used to combine the results. Meta-regression and subgroups analyses were used to explore potential sources of between-study heterogeneity. Publication bias was estimated using Egger's regression asymmetry test. Finally, 15 articles with 20 studies for vitamin C intake and eight articles with 10 studies for serum ascorbate were included in this meta-analysis. The relative risk (RR) and 95% confidence interval of cataract for the highest versus the lowest category of vitamin C intake was 0.814 (0.707-0.938), and the associations were significant in America and Asia. Significant association of cataract risk with highest versus the lowest category of serum ascorbate was found in general [0.704 (0.564-0.879)]. Inverse associations were also found between serum ascorbate and nuclear cataract and posterior subcapsular cataract. Higher vitamin C intake and serum ascorbate might be inversely associated with risk of cataract. Vitamin C intake should be advocated for the primary prevention of cataract. © 2015 Acta Ophthalmologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.

    Congenital cataract is a common cause of blindness in children; however, its pathogenesis remains unclear. Genetic factors have been shown to play an important role in the pathogenesis of congenital cataract. The current genetic models of congenital cataract include autosomal dominant, autosomal recessive, and sex-linked inheritance. Sex-linked congenital cataract could be inherited through the X or Y chromosome. Congenital cataract is a symptom associated with several X-linked disorders, including Nance-Horan syndrome, Lowe syndrome, Conradi-Hünermann-Happle syndrome, oculo-facio-cardio-dental syndrome, and Alport syndrome. On the other hand, the mechanism and characteristics of Y-linked congenital cataract remains to be identified. Despite its rarity, sex-linked congenital cataract has been known to seriously affect the quality of life of patients. In this review, we present our current understanding of the genes and loci associated with sex-linked congenital cataract. This could help identify novel approaches for the prevention, early diagnosis, and comprehensive disease treatment.

Vitamin K antagonists (VKA have been the standard of care for long-term OAT for decades, but non-VKA oral anticoagulants (NOAC have recently been approved for this indication, and raised many questions, among them their influence on medication adherence. We assessed adherence to VKA and NOAC in secondary stroke prevention. Methods: All patients treated from October 2011 to September 2012 for ischemic stroke or transient ischemic attack with a subsequent indication for OAT, at three academic hospitals were entered into a prospective registry, and baseline data and antithrombotic treatment at discharge were recorded. At the 1-year follow-up, we assessed the adherence to different OAT strategies and patients’ adherence to their respective OAT. We noted OAT changes, reasons to change treatment, and factors that influence persistence to the prescribed OAT. Results: In patients discharged on OAT, we achieved a fatality corrected response rate of 73.3% (n=209. A total of 92% of these patients received OAT at the 1-year follow-up. We observed good adherence to both VKA and NOAC (VKA, 80.9%; NOAC, 74.8%; P=0.243 with a statistically nonsignificant tendency toward a weaker adherence to dabigatran. Disability at 1-year follow-up was an independent predictor of lower adherence to any OAT after multivariate analysis, whereas the choice of OAT did not have a relevant influence. Conclusion: One-year adherence to OAT after stroke is strong (>90% and patients

    Full Text Available Abstract Background This study aimed to inform the design of a pragmatic trial of stroke prevention in primary care by evaluating data recorded in electronic patient records (EPRs as potential outcome measures. The study also evaluated achievement of recommended standards of care; variation between family practices; and changes in risk factor values from before to after stroke. Methods Data from the UK General Practice Research Database (GPRD were analysed for 22,730 participants with an index first stroke between 2003 and 2006 from 414 family practices. For each subject, the EPR was evaluated for the 12 months before and after stroke. Measures relevant to stroke secondary prevention were analysed including blood pressure (BP, cholesterol, smoking, alcohol use, body mass index (BMI, atrial fibrillation, utilisation of antihypertensive, antiplatelet and cholesterol lowering drugs. Intraclass correlation coefficients (ICC were estimated by family practice. Random effects models were fitted to evaluate changes in risk factor values over time. Results In the 12 months following stroke, BP was recorded for 90%, cholesterol for 70% and body mass index (BMI for 47%. ICCs by family practice ranged from 0.02 for BP and BMI to 0.05 for LDL and HDL cholesterol. For subjects with records available both before and after stroke, the mean reductions from before to after stroke were: mean systolic BP, 6.02 mm Hg; diastolic BP, 2.78 mm Hg; total cholesterol, 0.60 mmol/l; BMI, 0.34 Kg/m2. There was an absolute reduction in smokers of 5% and heavy drinkers of 4%. The proportion of stroke patients within the recommended guidelines varied from less than a third (29% for systolic BP, just over half for BMI (54%, and over 90% (92% on alcohol consumption. Conclusions Electronic patient records have potential for evaluation of outcomes in pragmatic trials of stroke secondary prevention. Stroke prevention interventions in primary care remain suboptimal but important

    Irrespective of its etiology, long-standing, non-self-limiting gastric inflammation (mostly in Helicobacter pylori-associated cases) is the cancerization ground on which epidemic (intestinal-type) gastric carcinoma (GC) can develop. The natural history of invasive gastric adenocarcinoma encompasses gastritis, atrophic mucosal changes, and intraepithelial neoplasia (IEN). The topography, the extent and the severity of the atrophic changes significantly correlate with the risk of developing both IEN and GC. In recent years, both noninvasive (serological) tests and invasive (endoscopy/biopsy) procedures have been proposed to stratify patients according to different classes of GC risk. As a consequence, different patient-tailored GC secondary prevention strategies have been put forward. This review summarizes the histological features of H. pylori-related gastritis and the natural history of the disease. Histological and serological strategies to assess GC risk as well as the clinical management of atrophic gastritis patients are also discussed. © 2014 S. Karger AG, Basel.

    People often seek and receive cancer information from mass media (including television, radio, print media, and the Internet), and marketing strategies often inform cancer information needs assessment, message development, and channel selection. In this article, we present the discussion of a 2-hour working group convened for a cancer communications workshop held at the 2008 Society of Behavioral Medicine meeting in San Diego, CA. During the session, an interdisciplinary group of investigators discussed the current state of the science for mass media and marketing communication promoting primary and secondary cancer prevention. We discussed current research, new research areas, methodologies and theories needed to move the field forward, and critical areas and disciplines for future research.

    Full Text Available Abstract The cornerstone in clinical evidence of the relative efficacy of thienopyridines (clopidogrel, ticlopidine versus aspirin in the secondary prevention of vascular disease is the Clopidogrel versus Aspirin in Patients at Risk of Ischaemic Events trial. This trial showed a modest benefit in the reduction of vascular events by clopidogrel. The results differed according to qualifying disorder: myocardial infarction, -3.7%; ischaemic stroke, +7.3%; and peripheral arterial disease, +23.8% (P = 0.042. Similar results were found for ticlopidine after brain ischaemia. The safety of clopidogrel appears to be similar to that of aspirin and better than that of ticlopidine. However, the recent report of thrombotic thrombocytopenic purpura in association with clopidogrel causes concern.

    An abundance of data, known for decades, is available linking metals, such as lead and cadmium, with cardiovascular disease. However, the idea that these toxic metals could be a modifiable risk factor for atherosclerosis did not become apparent clinically until the completion of the Trial to Assess Chelation Therapy in 2012. This pivotal study was the first double-blind, randomized, controlled trial of its kind to demonstrate a clear improvement in cardiovascular outcomes with edetate disodium therapy in a secondary prevention, post-myocardial infarction population. This effect size was most striking in diabetic patients, where the efficacy of edetate disodium was comparable, if not superior, to that of current guideline-based therapies. Given the economic burden of diabetes and cardiovascular disease, the potential impact of this therapy could be enormous if the results of this study are replicated.

    Secondary growth is driven by continuous cell proliferation and differentiation of the cambium that acts as vascular stem cells, producing xylem and phloem to expand vascular tissues laterally. During secondary growth of hypocotyls in Arabidopsis thaliana, the xylem undergoes a drastic phase transition from a parenchyma-producing phase to a fiber-producing phase at the appropriate time. However, it remains to be fully elucidated how progression of secondary growth is properly controlled. We focused on phenotypes of hypocotyl vasculatures caused by double mutation in ERECTA (ER) and ER-LIKE1 (ERL1) receptor-kinase genes to elucidate their roles in secondary growth. ER and ERL1 redundantly suppressed excessive radial growth of the hypocotyl vasculature during secondary growth. ER and ERL1 also prevented premature initiation of the fiber differentiation process mediated by the NAC SECONDARY WALL THICKENING PROMOTING FACTORs in the hypocotyl xylem. Upon floral transition, the hypocotyl xylem gained a competency to respond to GA in a BREVIPEDICELLUS-dependent manner, which was a prerequisite for fiber differentiation. However, even after the floral transition, ER and ERL1 prevented precocious initiation of the GA-mediated fiber formation. Collectively, our findings reveal that ER and ERL1 redundantly prevent premature progression of sequential events in secondary growth. © 2016 The Authors.

    Efforts to improve the secondary prevention of work-related upper extremity (WRUE) symptoms continue to present a challenge. As with many occupational musculoskeletal pain disorders no single, direct cause-effect relationship exists among specific exposures, pathologic processes, and symptoms. The field has yet to create truly effective and efficient interventions for these problems that are based on current epidemiological and clinical knowledge. A working conference was held in Annapolis, Maryland on September 23rd and 24th, 2005 with leaders in research and application related to upper extremity disorders to address this challenge. The intent of the meeting was to review "state of the art" evidence in epidemiology and intervention research in order to develop suggestions regarding next steps in intervention research and application. On day 2 a number of stakeholders were present to discuss what they perceived as the missing pieces in both epidemiological research and applied intervention research in order to generate more effective workplace interventions. The papers in this series of the Journal of Occupational Rehabilitation indicate that scientifically sound progress has been made over the past decade in identifying ergonomic, workplace psychosocial, and individual factors in both the etiology and exacerbation of these symptoms/disorders. However, there is a gap between this knowledge and the development and practical implementation of comprehensive interventions for these problems. The conference also highlighted the paucity of economic analyses of the impact of these disorders as well as the economic study of the impact of intervention. Approaches for such evaluations were presented and are included in this special section of the journal. This series of papers and the summary of the invited group's discussions provided in this paper clearly emphasize the need for innovative ways to think about these problems and specific research topics that can help

    Full Text Available ABSTRACT: Introduction & Objective: Hydatid cyst is located in human and some animal visceral organs such as liver and lung. The disease is considered as a medical, veterinary and economical problem in endemic area. When the hydatid cyst is ruptured, protoscolices from inside the cyst may spread out to other parts of the body and develops a new cyst named secondary hydatid cyst. In this research in an attempt to prevent secondary hydatid cyst, protective potential of protoscolices surface antigens extracted with different detergents has been investigated in animal model. Materials & Methods: In this experimental study, groups of Balb/c mice were immunized intra-peritoneally with protoscolices homogenate and three detergent (SDS, Tween and Triton x–100 extracted protoscolices surface antigens and alum as adjuvant. These mice were then boosted two times with the same antigens fortnightly. Control mice were simultaneously injected with alum alone. Two weeks following the last injection all the mice in cases and control groups were challenged with live protoscolices. Three months afterward all the mice in case and control groups were sacrificed and their peritoneal cavities were explored for hydatid cysts. Results: The mean of developed cyst number in mice injected with protoscolices homogenate was 3±2, while in control group the mean of developed cysts number was 5.8 ± 1.7 (p< 0.02. The mean of developed cyst number in mice injected with SDS, Tween and Triton x–100 extracted protoscolices surface antigens was 3, 3.6 and 3.4, respectively, while the mean of developed cyst number in control group was 5.8. Conclusion: The mean of cyst number in cases and control groups was different and this difference was statistically significant. Results of this investigation revealed that protoscolices homogenate antigens and some detergent extracted antigens are protective against secondary hydatid cyst infection

    A microcapsule-type self-healing protective coating with secondary crack preventing capability has been developed using a silanol-terminated polydimethylsiloxane (STP)/dibutyltin dilaurate (DD) healing agent. STP undergoes condensation reaction in the presence of DD to give a viscoelastic substance. STP- and DD-containing microcapsules were prepared by in-situ polymerization and interfacial polymerization methods, respectively. The microcapsules were characterized by Fourier-transform infrared (FT-IR) spectroscopy, optical microscopy, and scanning electron microscopy (SEM). The microcapsules were integrated into commercial enamel paint or epoxy coating formulations, which were applied on silicon wafers, steel panels, and mortar specimens to make dual-capsule self-healing protective coatings. When the STP/DD-based coating was scratched, self-healing of the damaged region occurred, which was demonstrated by SEM, electrochemical test, and water permeability test. It was also confirmed that secondary crack did not occur in the healed region upon application of vigorous vibration to the self-healing coating.

    Full Text Available Background: Narcotics have been present in the world for thousands of years. People have been trying to change their psyche by means of psychoactive drugs. At the very beginning drugs were used as the element of religious cult, helpful in varying social meetings. With time, they were used as medicinal substances. The phenomenon of narcosis among children and teenagers by means of various narcotics is one of the most serious aspects of social aberration and it is a very difficult educational problem all over the world. Drug abuse among teenagers is becoming more and more serious and is increasing, which puts health and life in danger. There are as many reasons of drug abuse as narcotics. Young people do not appreciate their health, as in their opinion illnesses are directly related to an old age. They do not understand the consequences of drug abuse which is just a good fun for them. The aim of drug prevention strategy is, first of all, the reduction of drugs availability. The prevention strategies concentrated on costs aim at helping the individuals to develop and keep the healthy way of life. The strategies concentrated on society should include the environmental factors, such as legal, economical, family, cultural, political and religious aspects. The aim of this work was to specify the awareness of secondary school students concerning drug abuse, its reasons, health effects and prevention. Materials and methods: The research was conducted among 80 students of 1–3 grade of secondary schools from Opatów province. The questionnaire was the research tool, which consisted of 21 questions concerning the students’ knowledge about the reasons for reaching for drugs, the possibilities of getting drugs at school, the health reasons of drug abuse as well as the drug prevention conducted by the teachers and school educationalists. Results: Only 25% of the students believed drug abuse to be a socially pathological phenomenon. 65% claimed that lately

    Functional foods are the most natural and safest source of health ingredients, providing health benefits beyond basic nutrition, and hence can be used as supplements for the prevention of secondary complications in diabetes. Persistent diabetes may cause glycation of various tissue proteins such as of those in lens, kidney, blood, and brain, which may further lead to the development of pathological conditions such as cataract and cardiovascular diseases. This study on adult rats was designed to assess if the functional food supplements A and B (proprietary blends of antioxidant rich plant materials) can reduce secondary complications such as cataract, dyslipidemia, and oxidative stress under severe diabetic conditions. After nine weeks of intervention of the supplements, it was found that the % HbA1c levels in the formulation group B significantly (p functional foods in the effective management of secondary complications associated with severe diabetic conditions.

    Worldwide, each year more than 7 million people experience myocardial infarction, in which one-year mortality rates are now in the range of 10%, but vary with patient characteristics. The consequences are even more dramatic: among patients who survive, 20% suffer a second cardiovascular event in the first year and approximately 50% of major coronary events occur in those with a previous hospital discharge diagnosis of ischaemic heart disease. The people behind these numbers spur this call for action. Prevention after myocardial infarction is crucial to reduce risk and suffering. Evidence-based interventions include optimal medical treatment with anti-platelets and statins, achievement of blood pressure, lipid and blood glucose targets, and appropriate lifestyle changes. The European Society of Cardiology and its constituent bodies are determined to embrace this challenge by developing a consensus document in which the existing gaps for secondary prevention strategies are reviewed. Effective interventions in relation to the patients, healthcare providers and healthcare systems are proposed and discussed. Finally, innovative strategies in hospital as well as in outpatient and long-term settings are endorsed.

    PurposeThe aim of this study is to report a case series of ocular complications including retinal detachment (RD) and cataract in atopic dermatitis (AD) and surgical management involving a majority of Caucasian patients.Patients and methodsThis study is an observational case series, originally designed as an audit. It involves detailed discussion of history, clinical features, and surgical management of patients presenting with retinal detachment and cataracts secondary to severe AD. Six consecutive patients with diagnosis of severe AD requiring posterior segment and cataract surgery were included in the study.ResultsEight eyes of six patients had retinal detachment. Most of them involved the temporal retina. The retinal breaks were located anteriorly close to the ora serrata in six eyes and Giant tear retinal (GRT) detachment was found in two eyes. Five eyes had proliferative vitreo-retinopathy (PVR) at presentation. All six patients had bilateral cataracts and cataract surgery was performed in eleven eyes. Bilateral simultaneous surgery was essential in two patients. Three eyes had secondary intra-ocular lens (IOL) implantation with pars plana vitrectomy for subluxed lens implant.ConclusionsAnterior retinal breaks and temporal RD are common in retinal detachment secondary to AD. PVR is often present, which makes surgical management difficult. Cataract formation is quite often and late subluxation of IOL may occur.

    Background Sickle cell disease is one of the commonest severe monogenic disorders in the world, due to the inheritance of two abnormal haemoglobin (beta globin) genes. Sickle cell disease can cause severe pain, significant end-organ damage, pulmonary complications, and premature death. Stroke affects around 10% of children with sickle cell anaemia (HbSS). Chronic blood transfusions may reduce the risk of vaso-occlusion and stroke by diluting the proportion of sickled cells in the circulation. This is an update of a Cochrane Review first published in 2002, and last updated in 2013. Objectives To assess risks and benefits of chronic blood transfusion regimens in people with sickle cell disease for primary and secondary stroke prevention (excluding silent cerebral infarcts). Search methods We searched for relevant trials in the Cochrane Library, MEDLINE (from 1946), Embase (from 1974), the Transfusion Evidence Library (from 1980), and ongoing trial databases; all searches current to 04 April 2016. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Haemoglobinopathies Trials Register: 25 April 2016. Selection criteria Randomised controlled trials comparing red blood cell transfusions as prophylaxis for stroke in people with sickle cell disease to alternative or standard treatment. There were no restrictions by outcomes examined, language or publication status. Data collection and analysis Two authors independently assessed trial eligibility and the risk of bias and extracted data. Main results We included five trials (660 participants) published between 1998 and 2016. Four of these trials were terminated early. The vast majority of participants had the haemoglobin (Hb)SS form of sickle cell disease. Three trials compared regular red cell transfusions to standard care in primary prevention of stroke: two in children with no previous long-term transfusions; and one in children and adolescents on long-term transfusion.

    The present study evaluates the effectiveness of a decision support system used to evaluate and control physical job stresses and prevent re-injury of workers who have experienced or are concerned about work-related musculoskeletal disorders. The software program is a database that stores detailed job information such as standardized work data, videos, and upper-extremity physical stress ratings for over 400 jobs in the plant. Additionally, the database users were able to record comments about the jobs and related control issues. The researchers investigated the utility and effectiveness of the software by analyzing its use over a 20-month period. Of the 197 comments entered by the users, 25% pertained to primary prevention, 75% pertained to secondary prevention, and 94 comments (47.7%) described ergonomic interventions. Use of the software tool improved primary and secondary prevention by improving the quality and efficiency of the ergonomic job analysis process.

    Full Text Available Luigi Fontana, Marco Coassin, Alfonso Iovieno, Antonio Moramarco, Luca Cimino Ophthalmology Unit, Arcispedale Santa Maria Nuova – IRCCS, Reggio Emilia, Italy Abstract: Pseudoexfoliation is a ubiquitous syndrome of multifactorial origin affecting elderly people by increasing the risk of cataract and secondary glaucoma development. Despite modern techniques and technologies for cataract surgery, pseudoexfoliation syndrome represents a challenge for surgeons because of the increased weakness of the zonular apparatus and limited pupil dilation. Due to the inherent difficulties during surgery, the risk of vitreous loss in these patients is several times higher than in cataract patients without pseudoexfoliation. Using currently available surgical devices (ophthalmic viscosurgical device, iris retractors and ring dilators, capsular tension ring, etc., the risk of intraoperative complications may be much reduced, allowing the surgeon to handle difficult cases with greater confidence and safety. This review analyzes the methodologic approach to the patient with zonular laxity with the aim of providing useful advices to limit the risks of intraoperative and postoperative complications. From the preoperative planning, to the intraoperative management of the small pupil and phacodonesis, and to the postoperative correction of capsule phimosis and intraocular lens dislocation, a step approach to the surgical management of pseudoexfoliation patients is illustrated.

    From this detailed analysis of the main dietary trials conducted over the last 30 years in the secondary prevention of coronary heart disease, it can be said that the older trials were conducted on low risk patients and used high fat diets (about 40% of energy as lipids), comprising low saturated fat and cholesterol intake but very high (15 to 20% of energy) polyunsaturated fat intake, particularly from the omega-6 fatty acid family. These experimental diets were designed to reduce blood cholesterol and failed to improve prognosis. By contrast, recent trials were not primarily designed to reduce cholesterol, were conducted in medium- and high-risk patients and used low fat diets supplemented by omega-3 fatty acids from various sources. In two of these trials, the consumption of natural antioxidants, oligoelements and vegetable proteins was increased. Recurrence rate was reduced in the range of 30 to 70%. One conclusion from these well-conducted recent experiments on more than 3000 patients is that new and more specific dietary recommendations are clearly warranted in secondary prevention of coronary heart disease. They should be more specific and more clearly defined and therefore different from those generally provided in the U.S.A. and Europe at present. In a recent Consensus Panel statement, authors wrote less than one line to describe a cardioprotective diet in patients with coronary heart disease, summarized as diet and coronary heart disease is more complex than the current cholesterol hypothesis. They identified at least seven major dietary factors, including fibres, although the evidence of an effect on coronary heart disease is weak. However, they did not mention vegetable and fish proteins which are rich in arginine and L-glutamine, major regulators of cardiovascular function. Thus, new dietary advice should include: reduce intake of total (not more than 30% of energy) and saturated (less than 10%) fats maintain intake at least minimally, of the essential

    Cardiovascular disease (CVD), a leading cause of morbidity and mortality, has similar incidence in metropolitan and rural areas but poorer cardiovascular outcomes for residents living in rural and remote Australia. Cardiac Rehabilitation (CR) is an evidence-based intervention that helps reduce subsequent cardiovascular events and rehospitalisation. Unfortunately CR attendance rates are as low as 10-30% with rural/remote populations under-represented. This in-depth assessment investigated the provision of CR and secondary prevention services in Western Australia (WA) with a focus on rural and remote populations. CR and Aboriginal Community Controlled Health Services were identified through the Directory of Western Australian Cardiac Rehabilitation and Secondary Prevention Services 2012. Structured interviews with CR coordinators included questions specific to program delivery, content, referral and attendance. Of the 38 CR services identified, 23 (61%) were located in rural (n = 11, 29%) and remote (n = 12, 32%) regions. Interviews with coordinators from 34 CR services (10 rural, 12 remote, 12 metropolitan) found 77% of rural/remote services were hospital-based, with no service providing a comprehensive home-based or alternative method of program delivery. The majority of rural (60%) and remote (80%) services provided CR through chronic condition exercise programs compared with 17% of metropolitan services; only 27% of rural/remote programs provided education classes. Rural/remote coordinators were overwhelmingly physiotherapists, and only 50% of rural and 33% of remote programs had face-to-face access to multidisciplinary support. Patient referral and attendance rates differed greatly across WA and referrals to rural/remote services generally numbered less than 5 per month. Program evaluation was reported by 33% of rural/remote coordinators. Geography, population density and service availability limits patient access to CR services in rural/remote WA. Current

  2. Carbon steel corrosion prevention during chemical cleaning of steam generator secondary side components

    2009-01-01

    During operation of a nuclear power plant, many contaminants, such as solid particles or dissolved species are formed in the secondary circuit, go into steam generator and deposit as scales on heat transfer tubing, support plate or as sludge on tube sheet. By accumulation of these impurities, heat transfer is reduced and the integrity of the steam generator tubing is influenced. Chemical cleaning is a qualified, efficient measure to improve steam generator corrosion performance. The corrosion mechanism can be counteracted by the chemical cleaning of the deposits on the tube sheet and the scales on the heat transfer tubing. The major component of the scales is magnetite, which can be dissolved using an organic chelating agent (ethylenediaminetetraacetic acid, EDTA) in combination with a complexing agent such as citric acid in an alkaline reducing environment. As the secondary side of SG is a conglomerate of alloys it is necessary to choose an optimal chemical cleaning solution for an efficient cleaning properties and at the same time with capability of corrosion prevention of carbon steel components during the process. The paper presents laboratory tests initiated to confirm the ability of this process to clean the SG components. The experiments followed two paths: - first, carbon steel samples have been autoclavized in specific secondary circuit solutions of steam generator to simulate the deposits constituted during operation of this equipment; - secondly, autoclavized samples have been cleaned with a solvent composed of EDTA citric acid, hydrazine of pH = 5 and temperature of 85 deg. C. Before chemical cleaning, the oxide films were characterized by surface analysis techniques including optical microscopy, scanning electron microscopy (SEM) and electrochemical impedance spectroscopy (EIS). Applied to dissolve corrosion products formed in a steam generator, the solvents based on chelating agents are aggressive toward carbon steels and corrosion inhibitors are

    There is little control of cardiovascular (CV) risk factors in secondary prevention after an ischaemic stroke, in part due to a lack of adherence to treatment. The CV polypill may contribute to proper treatment adherence, which is necessary for CV disease prevention. This study aimed to establish how and in what cases the CV polypill should be administered. A group of 8 neurologists drafted consensus recommendations using structured brainstorming and based on their experience and a literature review. These recommendations are based on the opinion of the participating experts. The use of the CV polypill is beneficial for patients, healthcare professionals, and the health system. Its use is most appropriate for atherothrombotic stroke, lacunar stroke, stroke associated with cognitive impairment, cryptogenic stroke with CV risk factors, and silent cerebrovascular disease. It is the preferred treatment in cases of suspected poor adherence, polymedicated patients, elderly people, patients with polyvascular disease or severe atherothrombosis, young patients in active work, and patients who express a preference for the CV polypill. Administration options include switching from individual drugs to the CV polypill, starting treatment with the CV polypill in the acute phase in particular cases, use in patients receiving another statin or an angiotensin ii receptor antagonist, or de novo use if there is suspicion of poor adherence. Nevertheless, use of the CV polypill requires follow-up on the achievement of the therapeutic objectives to make dose adjustments. This document is the first to establish recommendations for the use of the CV polypill in cerebrovascular disease, beyond its advantages in terms of treatment adherence.

    Fetal alcohol spectrum disorders (FASD) are a major public health problem that affects 2 to 5 percent of the population. Individuals with FASD are at high risk for secondary conditions, such as mental health problems, school disruptions, and trouble with the law. Evidence-based intervention programs are needed to prevent and treat secondary conditions in this population. The purpose of this study was to identify intervention program characteristics for preventing secondary conditions in individuals with FASD from the perspectives of parents and service providers. This qualitative study utilized a phenomenological approach to identify program characteristics for preventing secondary conditions. Twenty-five parents of children (ages 3 to 33) with FASD and 18 service providers participated in focus groups or individual interviews. Data was systematically analyzed using a framework approach. Themes did not differ by participant type. Participants emphasized five primary characteristics of intervention programs for individuals with FASD. Programs need to 1) be available to individuals across the lifespan, 2) have a prevention focus, 3) be individualized, 4) be comprehensive, and 5) be coordinated across systems and developmental stages. Participants discussed a variety of specific intervention strategies for each developmental stage and setting. Program characteristics identified in this study are consistent with a positive behavior support framework. This framework is discussed in the context of research on existing interventions for individuals with FASD, and recommendations for future intervention development and evaluation are highlighted.

    Advances in technology coupled with increased penetration of mobile phones and smart devices are rapidly changing healthcare delivery. Mobile phone applications ('apps'), text messages, and Internet platforms used alone or in combination are now providing interventions targeting people with multiple cardiovascular risk factors. The present article will review the emerging evidence regarding apps and discuss their potential role in providing secondary prevention interventions via mobile phones. Seven recent randomized controlled trials used text messages or apps for six to 12 months, with or without differing combinations of other technology platforms. All studies, involved cardiac and diabetes populations, and demonstrated at least one positive improvement to cardiovascular risk factor profiles. When measured, acceptability of the intervention was high. Mobile apps and technology can deliver positive outcomes in the management of cardiovascular risk factors. However, because of the complexity of combination interventions, it is difficult to determine the 'active' ingredient. A future challenge for researchers and clinicians will be to respond quickly to these rapidly evolving interventions in order to ensure the delivery of effective, evidence-based outcomes.

    2017-01-01

    The influence of fibrates on cardiovascular risk has been the focus of several clinical trials. This Cochrane Collaboration Systematic Review evaluated the efficacy of fibrates for secondary prevention of cardiovascular events and stroke, analyzing 13 randomized controlled trials, in a total of 16 112 participants with a history of cardiovascular disease. Fibrates showed a protective effect for the composite outcome of non-fatal stroke, non-fatal myocardial infarction (MI) and vascular death, mainly due to reduction in the risk of non-fatal or fatal MI. Nonetheless, these results largely relied on studies including clofibrate, a drug withdrawn from the market in 2002. No statistically significant differences regarding adverse events were found between fibrates and placebo. Although insufficient to support the routine prescription of fibrates in this setting, this evidence should be taken into account when deciding on lipid-modifying therapy in dyslipidemic patients with a history of cardiovascular disease.

    2008-01-01

    Improving mammography initiation and maintenance among African American women has been suggested as a strategy for reducing breast cancer mortality in this population. We examined cultural values in relation to self-reported breast cancer screening among 572 low-income, urban, African American women. Cultural values examined included time orientation, family authority, employment aspirations, value of past vs modern life, and reliance on medical professionals. Also, implications for continued development of culturally tailored health interventions and opportunities for the consideration of cultural values in health communication are discussed. Bivariate analyses showed that more traditional values were associated with worse screening histories and lower intentions for future screening. In multivariate analyses, two interactions were observed between cultural values and age: for younger women, more traditional values were associated with lower odds of having ever received a mammogram, and for older women, more traditional values were associated with lower odds of intentions to receive a mammogram in the next 2 years. This study adds to the evidence that cultural constructs, such as values, are associated with secondary prevention of breast cancer and supports the consideration of cultural constructs as important in increasing mammography and reducing breast cancer disparities for African American women.

    The aim of the study was to explore community-dwelling stroke patients' perceived barriers to healthy-lifestyle participation for secondary disease prevention, as well as their preferred means for risk-reduction information dissemination and motivators to participation in healthy-lifestyle interventions. Four focus groups (5-6 stroke survivors per group) were defined from community support groups. Key questions addressed barriers to healthy-lifestyle adoption, preferred methods for receiving information and factors that would engage participants in a risk-reduction programme. Groups were audiotaped, transcribed verbatim and analysed for thematic content using a framework approach. Twenty-two participants, 12 men, 10 women, mean age 71.4 (53-87) years, were included in the study. Three overarching themes emerged as barriers to healthy-lifestyle participation: physical, mental and environmental. Exercise participation difficulties spread across all three themes; healthy eating and smoking cessation concentrated in environmental and mental dimensions. Talks (discussions) were noted as participants' preferred method of information provision. Risk-reduction programmes considered attractive were stroke specific, convenient and delivered by healthcare professionals and involved both social and exercise components. Many stroke patients appear unable to adopt healthy-lifestyle changes through advice alone because of physical, mental and environmental barriers. Risk-reduction programmes including interactive education should be specifically tailored to address barriers currently experienced and extend beyond the stroke survivor to others in their environment who influence lifestyle choices.

We aimed to quantify the contribution of the two.We used the previously validated IMPACT model to estimate contributions from primary prevention (reducing risk factors in the population, particularly smoking, cholesterol and systolic blood pressure and from secondary prevention (reducing risk factors in coronary heart disease patients in the Swedish population.Between 1986 and 2002, about 8,690 fewer deaths were related to changes in the three major risk factors. Population cholesterol fell by 0.64 mmol/L, with approximately 5,210 fewer deaths attributable to diet changes (4,470 in healthy people740 in patients. plus 810 to statin treatment (200 in healthy people, 610 in patients. Overall smoking prevalence decreased by 10.3%, resulting in 1,195 fewer deaths, attributable to smoking cessation (595 in healthy people, 600 in patients. Mean population systolic blood pressure fell by 2.6 mmHg, resulting in 900 fewer deaths (865 in healthy people, 35 in patients, plus 575 fewer deaths attributable to antihypertensive medication in healthy people. The majority of falls in deaths attributable to risk factors occurred in people without known heart disease: 6,705 fewer deaths compared with 1,985 fewer deaths in patients (secondary prevention, emphasizing the importance of promoting health interventions in the general population.The largest effects on mortality came from primary prevention, giving markedly larger mortality reductions than secondary prevention.

    Cataract is currently the primary cause of blindness worldwide, and one of its main risk factors is solar ultraviolet radiation exposure. According to the localization of lens opacities, three main subtypes of cataract are recognized: nuclear, cortical and posterior subcapsular cataract. One of the main determinants of individual long-term solar radiation exposure is outdoor work. We systematically reviewed scientific literature from the last 20 years to update the recent development of research on the risk of cataract in outdoor workers and on the specific subtypes involved, also investigating the methods applied to evaluate the occupational risk. A total of 15 studies were included in the review, of which 12 showed a positive association. The studies confirm the relationship of long-term occupational solar radiation exposure with cortical cataract and give new support for nuclear cataract, although no substantial new data were available to support a relation with the posterior subcapsular subtype. In most of the studies, the exposure assessment was not adequate to support a representative evaluation of the ocular risk; however, outdoor work is clearly a relevant risk factor for cataract. Further research providing a better evaluation of the relation between solar radiation exposure levels and lens damage in workers is needed and aimed to establish adequate occupational exposure limits and better preventive measures, studying also their effectiveness. © 2018 Acta Ophthalmologica Scandinavica Foundation.

    Full Text Available Purpose. To investigate the activity of antioxidative enzymes and the products of oxidative stress in patients with age-related cataracts and compare the findings with those in healthy control subjects. Method. Sixty patients with age-related cataract and sixty healthy controls of matched age and gender were included in this study. Serum samples were obtained to detect the antioxidative enzymes of superoxide dismutase (SOD, catalase (CAT, and glutathione peroxidase (GSH-Px, and oxidation degradation products of malondialdehyde (MDA, 4-hydroxynonenal (4-HNE, conjugated diene (CD, advanced oxidation protein products (AOPP, protein carbonyl (PC, and 8-hydroxydeoxyguanosine (8-OHdG. Results. Serum SOD, GSH-Px, and CAT activities in cataract group were significantly decreased as compared to the control subjects (P<0.05. The levels of MDA, 4-HNE, and CD in cataract patients were significantly higher than those in the control subjects (P<0.05, P<0.01. Cataract patients had higher levels of 8-OHdG, AOPP, and PC with respect to the comparative group of normal subjects (P<0.01. And there was no statistical significance in concentration of antioxidative enzymes and oxidative stress products in patients with different subtype cataract. Conclusions. Oxidative stress is an important risk factor in the development of age-related cataract, and augmentation of the antioxidant defence systems may be of benefit to prevent or delay cataractogenesis.

    Secondary prevention medications reduce risk of stroke recurrence, yet many people do not receive recommended treatment, nor take medications optimally. Exploring how patients report making use of practitioners' advice on secondary prevention medicines on an online forum and what feedback was received from other participants. Thematic analysis of the archive of Talkstroke (2004-2011), UK. Posts including any secondary prevention medication terms, General Practitioner (GP) and their replies were identified. Fifity participants talked about practitioners' advice on secondary prevention medications in 43 discussion threads. Patients consulted practitioners for reassurance and dealing with side effects. Practitioners' advice varied from altering to maintaining current treatment. Three main themes emerged from the use of practitioners' advice: patients following advice (reassured, happy when side effects made tolerable, or still retaining anxiety about treatment); patients not following advice (admitting adherence on-off or stopping medications as side effects still not tolerable); asking other participants for feedback on advice received. Practitioners' advice was disregarded mainly when related to dealing with statin side effects, after one or two consultations. Themes for feedback involved sharing experience, directing back to practitioners, or to external evidence. Side effects of secondary prevention medications and statins in particular, cause anxiety and resentment in some patients, and their concerns are not always addressed by practitioners. Practitioners could consider more proactive strategies to manage such side effects. Forum feedback was appropriate and supportive of the practitioners' advice received. Our findings from peer-to-peer online conversations confirm and widen previous research. © The Author 2017. Published by Oxford University Press.

    Outdoor professionals such as mountain guides are at a substantial risk of developing non-melanoma skin cancer (NMSC) due to solar ultraviolet radiation (UVR) exposure. Despite major recent primary prevention efforts, studies on secondary skin cancer prevention efforts are limited and corresponding data on outdoor workers scarce. To assess the sun-protective behavior and individual motivations for or against skin cancer screening examinations in the German mountain guide population to aid in the development of effective awareness and prevention strategies. A cross-sectional study among all registered mountain guides in Germany was conducted using a 35-item online questionnaire on primary and secondary prevention of NMSC as well as perceived barriers for prevention. A total of 145 mountain guides participated in the study in January 2017. Of these, 86.2% reported using sunscreen often or always, 62.1% with a sun protection factor (SPF) of 30-50; and 60.7% had undergone dermatological examination by a medical professional. The most common reasons for using secondary prevention efforts were hope of an early diagnosis (77.3%), fear of skin cancer (73.9%), and the intention to be aware of one's own health (70.5%). The main reasons for not doing so were absence of conspicuous skin conditions (63.2%), and feeling healthy (59.6%). Awareness of prevention strategies recommended by the scientific community is low among affected occupationally high-risk mountain guide populations. Understanding the specific needs of this high-risk group is essential for the development of sustainable awareness and prevention strategies. This article is protected by copyright.

    To provide resource-stratified, evidence-based recommendations on the secondary prevention of cervical cancer globally. ASCO convened a multidisciplinary, multinational panel of oncology, primary care, epidemiology, health economic, cancer control, public health, and patient advocacy experts to produce recommendations reflecting four resource-tiered settings. A review of existing guidelines, a formal consensus-based process, and a modified ADAPTE process to adapt existing guidelines were conducted. Other experts participated in formal consensus. Seven existing guidelines were identified and reviewed, and adapted recommendations form the evidence base. Four systematic reviews plus cost-effectiveness analyses provided indirect evidence to inform consensus, which resulted in ≥ 75% agreement. Human papillomavirus (HPV) DNA testing is recommended in all resource settings; visual inspection with acetic acid may be used in basic settings. Recommended age ranges and frequencies by setting are as follows: maximal: ages 25 to 65, every 5 years; enhanced: ages 30 to 65, if two consecutive negative tests at 5-year intervals, then every 10 years; limited: ages 30 to 49, every 10 years; and basic: ages 30 to 49, one to three times per lifetime. For basic settings, visual assessment is recommended as triage; in other settings, genotyping and/or cytology are recommended. For basic settings, treatment is recommended if abnormal triage results are present; in other settings, colposcopy is recommended for abnormal triage results. For basic settings, treatment options are cryotherapy or loop electrosurgical excision procedure; for other settings, loop electrosurgical excision procedure (or ablation) is recommended. Twelve-month post-treatment follow-up is recommended in all settings. Women who are HIV positive should be screened with HPV testing after diagnosis and screened twice as many times per lifetime as the general population. Screening is recommended at 6 weeks postpartum in

    Full Text Available Abstract Background Internationally, guidelines to prevent secondary transmission of Shigella infection vary widely. Cases, their contacts with diarrhoea, and those in certain occupational groups are frequently excluded from work, school, or daycare. In the Netherlands, all contacts attending pre-school (age 0–3 and junior classes in primary school (age 4–5, irrespective of symptoms, are also excluded pending microbiological clearance. We identified risk factors for secondary Shigella infection (SSI within households and evaluated infection control policy in this regard. Methods This retrospective cohort study of households where a laboratory confirmed Shigella case was reported in Amsterdam (2002–2009 included all households at high risk for SSI (i.e. any household member under 16 years. Cases were classified as primary, co-primary or SSIs. Using univariable and multivariable binomial regression with clustered robust standard errors to account for household clustering, we examined case and contact factors (Shigella serotype, ethnicity, age, sex, household size, symptoms associated with SSI in contacts within households. Results SSI occurred in 25/ 337 contacts (7.4%: 20% were asymptomatic, 68% were female, and median age was 14 years (IQR: 4–38. In a multivariable model adjusted for case and household factors, only diarrhoea in contacts was associated with SSI (IRR 8.0, 95% CI:2.7-23.8. In a second model, factors predictive of SSI in contacts were the age of case (0–3 years (IRRcase≥6 years:2.5, 95% CI:1.1-5.5 and 4–5 years (IRRcase≥6 years:2.2, 95% CI:1.1-4.3 and household size (>6 persons (IRR2-4 persons 3.4, 95% CI:1.2-9.5.

    The aim of the study was to examine the effectiveness of the smoking prevention program "I do not smoke, I exercise" implemented with elementary and secondary school students. "I do not smoke, I exercise" is a theory-based smoking prevention program that promotes exercise as an alternative of smoking. The program consists of eight sessions implemented weekly. Participants were 338 Greek students (135 elementary and 203 secondary students) who were pre- and posttested in smoking, program, and exercise-related measures. The results showed that the program had significant effects on elementary students' attitudes toward smoking, intention to smoke, subjective norms, attitudes toward the application of the program, and knowledge about the health consequences of smoking. For secondary students, significant effects were found on students' perceived behavioral control and knowledge about the health consequences of smoking, while very few students reported a smoking experience before and after the intervention. Therefore the program "I do not smoke, I exercise" may have positive effects on variables related with smoking behavior. Differences in the program's impact on elementary and secondary students were identified. All these are discussed with reference to the need of implementing smoking prevention programs in schools contexts. © 2016 Society for Public Health Education.

    Studies suggest a J-shaped association between blood pressure and cardiovascular events in the setting of intensive systolic blood pressure control; whether there is a similar association with stroke remains less well established. The Secondary Prevention of Small Subcortical Strokes was a randomized trial to evaluate higher (130-149 mm Hg) versus lower (blood pressure targets in participants with recent lacunar infarcts. We evaluated the association of mean achieved blood pressure, 6 months after randomization, and recurrent stroke, major vascular events, and all-cause mortality. After a mean follow up of 3.7 years, there was a J-shaped association between achieved blood pressure and outcomes; the lowest risk was at ≈124 and 67 mm Hg systolic and diastolic blood pressure, respectively. For example, above a systolic blood pressure of 124 mm Hg, 1 standard deviation higher (11.1 mm Hg) was associated with increased mortality (adjusted hazard ratio: 1.9; 95% confidence interval: 1.4, 2.7), whereas below this level, this relationship was inverted (0.29; 0.10, 0.79), Pblood pressure of 67 mm Hg, a 1 standard deviation higher (8.2 mm Hg) was associated with an increased risk of stroke (2.2; 1.4, 3.6), whereas below this level, the association was in the opposite direction (0.34; 0.13, 0.89), P=0.02 for interaction. The lowest risk of all events occurred at a nadir of ≈120 to 128 mm Hg systolic blood pressure and 65 to 70 mm Hg diastolic blood pressure. Future studies should evaluate the impact of excessive blood pressure reduction, especially in older populations with preexisting vascular disease. URL: http://www.clinicaltrials.gov.

    Full Text Available Aim. To reveal peculiarities of arterial hypertension (AH diagnosis and therapy and their matching with international and national guidelines on AH. Material and Methods. An interview among Moscow physicians dealing with hypertensive patients was conducted in April-June 2005. Interview was taken with specially worked out forms containing 15 questions about hypertensive patient management. 102 physicians took part in interviewing, among them 65 internists and 37 cardiologists. Among interviewed physicians 56 ones were from outpatient clinics, 19 - from diagnostic centers, 14 - from hospitals, 5 - from commercial medical centers, 4 - from research center and 3 physicians had private practice.  Results. 80,4% of interviewed physicians correctly determined the main goals of AH therapy. 16% of doctors did not indicate blood pressure level below 140/90 mm Hg as target level of secondary prevention. Mainly antihypertensive therapy was presented by four classes of medicines, their shares were as follow: ACE inhibitors - 35%, beta-blockers – 28%, diuretics – 26% and calcium antagonists – 10%. Other classes of antihypertensive medicines (antagonists of angiotensin-II receptors, central acting medicines made about 1% of share. When choosing original medicine among several suggested trade marks, only 22% of doctors defined the medicine correctly. Original medicines made only 29,4% prescriptions in real medical practice. Conclusion. Real practice of AH diagnosis and therapy considerably differs from international and national guidelines on AH. It is possibly related with lack of appropriate knowledge among physicians as well as problems in public health service.

    Objective: To document the effects of secondary prevention on different risk factors in the real world situation. Methodology: It was a cross sectional comparative study carried out at a referral cardiac clinic in Peshawar from January 2010 to December 2010. Study subjects presenting with at least 6 months follow up were included from different parts of Khyber Pukhtunkhawa. All patients with positive history or objective evidence of CAD were enrolled. Study subjects were divided in two groups based on the fact that either taking or had stopped medication for the duration of the study period. Study variables were levels of lipids, glucose, blood pressure (BP), smoking and obesity. Results: A total of 843 patients were included in the study. Males were 70.4 % (593). Mean age was 58.74 +- 10.6 years. Patients taking regular medicine were 69.03% while 30.97% had stopped their medicine for at least three months. Diabetics, hypertensive and positive family history for CAD were 33.4%, 50.25% and 24% respectively. When compared to patient who had stopped medicine, mean systolic BP (p= 0.014), diastolic BP (p= 0.05), mean Cholesterol (p=0.000), mean LDL (p=0.000), mean HDL (p=0.000) and HbA1c% (p=0.049), was well controlled in patients who were taking medicine regularly. Mean BMI (p=0.786), triglycerides and smoking (p=0.761) had no significant difference between the two groups. Conclusion: Blood pressure, serum cholesterol, LDL, HDL, as well as HbA1c% were reduced with little effect on serum TGs, BMI and smoking in those who were taking medicine regularly compared to those who had stopped.

    The aim of this study was to evaluate whether the remote introduction of electronic decision support tools into family practices improves risk factor control after first stroke. This study also aimed to develop methods to implement cluster randomized trials in stroke using electronic health records. Family practices were recruited from the UK Clinical Practice Research Datalink and allocated to intervention and control trial arms by minimization. Remotely installed, electronic decision support tools promoted intensified secondary prevention for 12 months with last measure of systolic blood pressure as the primary outcome. Outcome data from electronic health records were analyzed using marginal models. There were 106 Clinical Practice Research Datalink family practices allocated (intervention, 53; control, 53), with 11 391 (control, 5516; intervention, 5875) participants with acute stroke ever diagnosed. Participants at trial practices had similar characteristics as 47,887 patients with stroke at nontrial practices. During the intervention period, blood pressure values were recorded in the electronic health records for 90% and cholesterol values for 84% of participants. After intervention, the latest mean systolic blood pressure was 131.7 (SD, 16.8) mm Hg in the control trial arm and 131.4 (16.7) mm Hg in the intervention trial arm, and adjusted mean difference was -0.56 mm Hg (95% confidence interval, -1.38 to 0.26; P=0.183). The financial cost of the trial was approximately US $22 per participant, or US $2400 per family practice allocated. Large pragmatic intervention studies may be implemented at low cost by using electronic health records. The intervention used in this trial was not found to be effective, and further research is needed to develop more effective intervention strategies. http://www.controlled-trials.com.

    Worldwide at least 100 million people are thought to have prevalent cardiovascular disease (CVD). This population has a five times greater chance of suffering a recurrent cardiovascular event than people without known CVD. Secondary CVD prevention is defined as action aimed to reduce the probability of recurrence of such events. Drug interventions have been shown to be cost-effective in reducing this risk and are recommended in international guidelines. However, adherence to recommended treatments remains sub-optimal. In order to influence non-adherence, there is a need to develop scalable and cost-effective behaviour-change interventions. To assess the effects of mobile phone text messaging in patients with established arterial occlusive events on adherence to treatment, fatal and non-fatal cardiovascular events, and adverse effects. We searched CENTRAL, MEDLINE, Embase, the Conference Proceedings Citation Index - Science on Web of Science on 7 November 2016, and two clinical trial registers on 12 November 2016. We contacted authors of included studies for missing information and searched reference lists of relevant papers. We applied no language or date restrictions. We included randomised trials with at least 50% of the participants with established arterial occlusive events. We included trials investigating interventions using short message service (SMS) or multimedia messaging service (MMS) with the aim to improve adherence to medication for the secondary prevention of cardiovascular events. Eligible comparators were no intervention or other modes of communication. We used standard methodological procedures expected by Cochrane. In addition, we attempted to contact all authors on how the SMS were developed. We included seven trials (reported in 13 reports) with 1310 participants randomised. Follow-up ranged from one month to 12 months. Due to heterogeneity in the methods, population and outcome measures, we were unable to conduct meta-analysis on these studies

    The Internet could provide a means of delivering secondary prevention programmes to people with coronary heart disease (CHD). To determine the effectiveness of Internet-based interventions targeting lifestyle changes and medicines management for the secondary prevention of CHD. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, in December 2014. We also searched six other databases in October 2014, and three trials registers in January 2015 together with reference checking and handsearching to identify additional studies. Randomised controlled trials (RCTs) evaluating Internet-delivered secondary prevention interventions aimed at people with CHD. Two review authors independently assessed risk of bias and extracted data according to the Cochrane Handbook for Systematic Reviews of Interventions. We assessed evidence quality using the GRADE approach and presented this in a 'Summary of findings' table. Eighteen trials met our inclusion criteria. Eleven studies are complete (1392 participants), and seven are ongoing. Of the completed studies, seven interventions are broad, targeting the lifestyle management of CHD, and four focused on physical activity promotion. The comparison group in trials was usual care (n = 6), minimal intervention (n = 3), or traditional cardiac rehabilitation (n = 2).We found no effects of Internet-based interventions for all-cause mortality (odds ratio (OR) 0.27, 95% confidence interval (CI) 0.04 to 1.63; participants = 895; studies = 6; low-quality evidence). There was only one case of cardiovascular mortality in a control group (participants = 895; studies = 6). No incidences of non-fatal re-infarction were reported across any of the studies. We found no effects for revascularisation (OR 0.69, 95% CI 0.37 to 1.27; participants = 895; studies = 6; low-quality evidence).We found no effects for total cholesterol (mean difference (MD) 0.00, 95% CI -0.27 to 0.28; participants = 439; studies = 4; low

    Full Text Available Blindness in children is considered a priority area for VISION 2020, as visually impaired children have a lifetime of blindness ahead of them. Various studies across the globe show that one-third to half of childhood blindness is either preventable or treatable1 and that cataract is the leading treatable cause of blindness in children.The 8th General Assembly of the International Agency for the Prevention of Blindness (IAPB provided an opportunity to be acquainted with recent research and programme development work in the prevention of childhood blindness.

    Full Text Available IntroductionChildhood cataract, congenital and traumatic, is the most common treatable cause of childhood blindness, being responsible for 10 to 30 per cent of all childhood blindness. Preventing blindness from childhood cataract requires not only high-quality paediatric surgery, but also an awareness of parents’ understanding of the eye problem, and why they might not agree to surgery for their child. Several studies have examined the medical and social aspects of childhood cataract. Foster et al.1 point out that childhood blindness has huge socio-economic costs, and restoring the sight of one child blind from cataract is considered equivalent to restoring the sight of 10 elderly adults. It is therefore crucial that we understand why parents might not take up the option of surgery.

  13. Advances in visual correction and postoperative visual treatment of congenital cataract

    Full Text Available Congenital cataract is one of the important diseases that cause irreversible visual impairment on children. Compared with adult cataract, the surgery of congenital cataract is more complicated and the complications are more severer, especially the postoperative amblyopia often leads to bad prognosis. Therefore, the postoperative treatment is necessary to obtain the better visual outcome. The traditional visual correction methods after surgery include the combined use of spectacles, contact lens, and intraocular lens(IOL, but some problems such as IOL power calculation and IOL implantation time are still controversial. Besides, occlusion therapy and visual training are also essential for preventing amblyopia after cataract surgery. Occlusion in an appropriate dose and course must be mastered, accompanied by visual training. Both of the operative eyes and normal eyes will be able to achieve much better visual acuity and color sensitivity, so that the binocular vision can recover and develop as normal function.

    Normal development of the visual system in infants relies on clear images being projected onto the retina, which can be disrupted by lens opacity caused by congenital cataract. This disruption, if uncorrected in early life, results in amblyopia (permanently decreased vision even after removal of the cataract). Doctors are able to prevent amblyopia by removing the cataract during the first several weeks of life, but this surgery risks a host of complications, which can be equally visually disabling. Here, we investigated the feasibility of focusing light noninvasively through highly scattering cataractous lenses to stimulate the retina, thereby preventing amblyopia. This approach would allow the cataractous lens removal surgery to be delayed and hence greatly reduce the risk of complications from early surgery. Employing a wavefront shaping technique named time-reversed ultrasonically encoded optical focusing in reflection mode, we focused 532-nm light through a highly scattering ex vivo adult human cataractous lens. This work demonstrates a potential clinical application of wavefront shaping techniques.

    Full Text Available Background. Chaperone activity of α-crystallin in the lens works to prevent protein aggregation and is important to maintain the lens transparency. This study evaluated the effect of hesperetin on lens chaperone activity in selenite-induced cataracts. Methodology. Thirteen-day-old rats were divided into four groups. Animals were given hesperetin (groups G2 and G4 or vehicle (G1 and G3 on Days 0, 1, and 2. Rats in G3 and G4 were administered selenite subcutaneously 4 hours after the first hesperetin injection. On Days 2, 4, and 6, cataract grades were evaluated using slit-lamp biomicroscopy. The amount of a-crystallin and chaperone activity in water-soluble fraction were measured after animals sacrificed. Results. G3 on day 4 had developed significant cataract, as an average cataract grading of 4.6 ± 0.2. In contrast, G4 had less severe central opacities and lower stage cataracts than G3, as an average cataract grading of 2.4 ± 0.4. The a-crystallin levels in G3 lenses were lower than in G1, but the same as G4. Additionally, chaperone activity was weaker in G3 lenses than G1, but the same as in G4. Conclusions. Our results suggest that hesperetin can prevent the decreasing lens chaperone activity and a-crystallin water solubility by administered of selenite.

    Two cases of adrenomyeloneuropathy (AMN) in a family and the results of their MRI study are reported. Case 1, a 24-year-old male proband, was admitted to our hospital because of gait disturbance for three years. Bilateral cataracts were pointed out at birth, which required left side lenticotomy at age four. Neurological examinations on admission revealed a marked spastic paraparesis with pathological reflexes and a mild hypesthesia in the distal part of the left leg. No abnormal findings were detected in X-ray studies on the spine and spinal cord, electromyography and nerve conduction test. Serum very long chain fatty acids (VLCFAs) levels were apparently elevated, and the serum cortisol response to ACTH was low. Case 2, a 53-year-old woman, is the mother of Case 1 having a complaint of gait disturbance since age 51. She presented a mild spastic paraparesis with localized hypesthesia in the distal part of the both legs. She also had bilateral congenital cataracts. Her serum VLCFAs analysis indicated the intermediate levels between that of AMN and the normal control. Adrenal functions were normal. Cranial MRI (TR 2,000 msec/TE 80 msec) study disclosed high signal intensity areas in bilateral internal capsules in Case 1. These findings, suggesting the pathological change of dysmyelination, seemed to be well compatible with the clinical pictures. With these clinical findings and the laboratory data, these two cases were diagnosed as AMN. In addition, association of congenital cataract with AMN in both cases was characteristic in this family, which hasn't been reported in the literature. On regarding the genetic background of these two disorders, AMN and congenital cataract, it was speculated that each gene could be closely located on the same or very adjacent locus, possibly on Xq.

    Full Text Available Abstract Introduction Measuring the patient satisfaction is a very important issue that will help very much in improving the service provided to patients and improve the level of satisfaction. Aim To evaluate patient satisfaction with the cataract surgery service and identify any areas for improvement, determination of patient satisfaction with referral, out-patient consultation, pre-assessment clinic, surgery and post-operative care, also to report patients' comments relating to improvement in service provision. Methodology A retrospective study was undertaken for 150 patients underwent cataract surgery at Barrow General Hospital, UK, the survey sample was by postal questionnaires. We collected our data from the theatre lists for a period of 4 month. Results This study included 150 patients; the response rate was (72% 108 patients, Most patients were referred from their general practitioner 86.1%, 93 (86.1% patients were happy with the time interval from seeing their GP to eye clinic. In the eye out patient department many factors significantly affected the level of patient satisfaction, in general the more information provided for the patient the more the satisfaction. Conclusion Patient satisfaction is on important health outcome old understanding both the domains of satisfaction as well as their relative importance to patients is necessary to improve the overall quality of patient care. Meeting the doctor, presenting all relevant information and giving printed information are very important factors in improving the patient's satisfaction with cataract surgery.

  19. Dual Antiplatelet Therapy in Secondary Prevention of Ischemic Stroke: A Ghost from the Past or a New Frontier?

    Directory of Open Access Journals (Sweden)

    Clotilde Balucani

    2010-01-01

    Full Text Available With majority of ischemic strokes attributable to atherothrombosis and many being predictable after transient ischemic attacks (TIA, the role of early secondary prevention with antiplatelet agents is under renewed investigation. Prior major clinical trials of various secondary stroke prevention regimens pointed to a greater efficacy of dual antiplatelet agents if initiated early from symptom onset. This paper examines data and rationale behind dual antiplatelet regimens across the completed clinical trials. The safety of dual antiplatelets approach is of concern, but it could be outweighed, at least in early management, by a greater reduction in recurrence of ischemic events since this risk is “front loaded” after minor stroke or TIA. Aspirin monotherapy, though considered standard of care, is compared to aspirin-extended release dipiridamole and its combination with clopidogrel in early-phase completed and efficacy-phase ongoing clinical trials.

    To identify the underlying genetic defect in a Chinese family affected with autosomal dominant congenital nuclear cataract. A four-generation Chinese family with inherited nuclear cataract phenotype was recruited. Detailed family history and clinical data were recorded. All reported nuclear cataract-related candidate genes were screened for causative mutations by direct DNA sequencing. Effects of amino acid changes on the structure and function of protein were predicted by bioinformatics analysis. All affected individuals in this family showed nuclear cataracts. Sequencing of the candidate genes revealed a heterozygous c.559C>T change in the coding region of the major intrinsic protein (MIP), which caused a substitution of highly conserved arginine by cysteine at codon 187 (p.R187C). This mutation co-segregated with all affected individuals and was not observed in unaffected family members or 110 ethnically matched controls. Bioinformatics analysis showed that the mutation was predicted to affect the function and secondary structure of MIP protein. This study identified a novel disease-causing mutation p.R187C in MIP in a Chinese cataract family, expanding the mutation spectrum of MIP causing congenital cataract.

    Secondary stroke prevention is an important goal of poststroke patient treatment. Various pharmacologic approaches have been advocated, but the relative efficacy and safety of these regimens has remained the subject of much debate. Recently released data from the European/Australasian Stroke Prevention in Reversible Ischemia Trial (ESPRIT) indicated that combination therapy with aspirin and extended-release dipyridamole was more effective than aspirin monotherapy, and probably more effective than anticoagulants, for the prevention of cerebrovascular events after a stroke or transient ischemic attack. When viewed in light of results of earlier trials, these findings confirmed that combination aspirin plus extended-release dipyridamole therapy improved outcomes in these patients and is a recommended option for poststroke patient treatment.

    2017-01-01

    Cataracts are a significant cause of blindness and visual impairment worldwide. The present article reviews the literature and describes the current extent of cataracts globally, barriers to treatment, and recommendations for improving the treatment of cataracts. Prevalence and absolute number of blind because of cataracts remain high, although rates are declining in many areas globally. The age-standardized prevalence of blindness in adults older than 50 remains highest in western sub-Saharan Africa, with a rate of 6.0%. The greatest declines in age-standardized blindness because of cataracts in adults older than 50 between 1990 and 2010 were in East Asia, tropical Latin America, and western Europe. Recent studies have largely found higher rates of cataracts in women than in men. A new simulator for training ophthalmologists in manual small-incision cataract surgery holds promise for the future. The rates of cataract surgery are increasing and postoperative outcomes are improving worldwide, yet challenges to reducing the cataract burden further remain. Cost, an insufficient number of ophthalmologists, and low government funding remain significant barriers but investment in further eye care infrastructure and training of additional ophthalmologists would improve the current situation.

    There is little evidence on the use of secondary prevention medicines for cardiovascular disease by socioeconomic groups in countries at different levels of economic development. We assessed use of antiplatelet, cholesterol, and blood-pressure-lowering drugs in 8492 individuals with self-reported cardiovascular disease from 21 countries enrolled in the Prospective Urban Rural Epidemiology (PURE) study. Defining one or more drugs as a minimal level of secondary prevention, wealth-related inequality was measured using the Wagstaff concentration index, scaled from -1 (pro-poor) to 1 (pro-rich), standardised by age and sex. Correlations between inequalities and national health-related indicators were estimated. The proportion of patients with cardiovascular disease on three medications ranged from 0% in South Africa (95% CI 0-1·7), Tanzania (0-3·6), and Zimbabwe (0-5·1), to 49·3% in Canada (44·4-54·3). Proportions receiving at least one drug varied from 2·0% (95% CI 0·5-6·9) in Tanzania to 91·4% (86·6-94·6) in Sweden. There was significant (pSaudi Arabia, China, Colombia, India, Pakistan, and Zimbabwe. Pro-poor distributions were observed in Sweden, Brazil, Chile, Poland, and the occupied Palestinian territory. The strongest predictors of inequality were public expenditure on health and overall use of secondary prevention medicines. Use of medication for secondary prevention of cardiovascular disease is alarmingly low. In many countries with the lowest use, pro-rich inequality is greatest. Policies associated with an equal or pro-poor distribution include free medications and community health programmes to support adherence to medications.

    Evaluation of the fire prevention and ventilation systems and the secondary effects on safety at the Ignalina NPP from the point of view of fire hazard using computerized system is presented. Simplified screening algorithms for fire prevention, ventilation and the evaluation of secondary effects are developed, which allow accelerating fire hazard analysis at the Ignalina NPP. The analysis indicated that the fire prevention systems practically meet the national requirements and international recommendations for fire prevention. But it is necessary to introduce in separate rooms the measures improving fire prevention to guarantee the effective functioning of the ventilation systems and the reduction of the influence of secondary effects on safety. Computerized system of fire prevention and ventilation systems and evaluation of secondary effects on safety can be easily applied for fire hazard analysis at different big plants. (author)

    Medications are highly effective at reducing risk of recurrent stroke, but success is influenced by adherence to treatment. Among survivors of stroke and transient ischaemic attack (TIA), adherence to medication is known to be suboptimal. To identify and report barriers to medication adherence for the secondary prevention of stroke/TIA. A qualitative interview study was conducted within general practice surgeries in the East of England, UK. Patients were approached by letter and invited to take part in a qualitative research study. Semi-structured interviews were undertaken with survivors of stroke, caregivers, and GPs to explore their perspectives and views around secondary prevention and perceived barriers to medication adherence. Key themes were identified using a grounded theory approach. Verbatim quotes describing the themes are presented here. In total, 28 survivors of stroke, including 14 accompanying caregivers and five GPs, were interviewed. Two key themes were identified. Patient level barriers included ability to self-care, the importance people attach to a stroke event, and knowledge of stroke and medication. Medication level barriers included beliefs about medication and beliefs about how pills work, medication routines, changing medications, and regimen complexity and burden of treatment. Patients who have had a stroke are faced with multiple barriers to taking secondary prevention medications in UK general practice. This research suggests that a collaborative approach between caregivers, survivors, and healthcare professionals is needed to address these barriers and facilitate medication-taking behaviour. © British Journal of General Practice 2016.

    the lens response to oxidative damages, aging and health, cataract versus neuroendocrine regulation and disease. The cumulative results demonstrate that carnosine, released ophthalmically from the patented 1% Nacetylcarnosine prodrug lubricant eye drops, at physiological concentration might remarkably reduce the rate of telomere shortening in the lens cells subjected to oxidative stress in the lack of efficient antioxidant lens protection. Carnosine promotes the protection of normal cells from acquiring phenotypic characteristics of cellular senescence. The data of visual functions (visual acuity, glare sensitivity) in older adult subjects and older subjects with cataract treated with 1% N-acetylcarnosine lubricant eye drops showed significant improvement as compared, by contrast with the control group which showed generally no improvement in visual functions, with no difference from baseline in visual acuity and glare sensitivity readings. N-acetylcarnosine derived from the lubricant eye drops may be transported into the hypothalamic tuberomammillary nucleus (TMN) histamine neurons and gradually hydrolyzed. The resulting L-histidine may subsequently be converted into histamine, which could be responsible for the effects of carnosine on neurotransmission and hormone-like antiaging and anti-cataract physiological function. The research utilizing the N-acetylcarnosine lubricant eye drops powerful therapeutic platform provides the findings related to the intraocular uptake exposure sources as well as a timing dosage and duration systemic absorption of said preparation from the conjunctional sac reaching the hypothalamus with activities transfer into the hypothalamic-neuroendocrine pathways affecting across the hypothalamus metabolic pathway the telomere biology and cataract disease occurrence, reversal and prevention and the average expected lifespan of an individual. Such findings can be translated into clinical practice and may provide a basis for personalized cataract

    Full Text Available Abstract Background Fractures associated with bone fragility in older adults signal the potential for secondary fracture. Fragility fractures often precipitate further decline in health and loss of mobility, with high associated costs for patients, families, society and the healthcare system. Promptly initiating a coordinated, comprehensive pharmacological bone health and falls prevention program post-fracture may improve osteoporosis treatment compliance; and reduce rates of falls and secondary fractures, and associated morbidity, mortality and costs. Methods/design This pragmatic, controlled trial at 11 hospital sites in eight regions in Quebec, Canada, will recruit community-dwelling patients over age 50 who have sustained a fragility fracture to an intervention coordinated program or to standard care, according to the site. Site study coordinators will identify and recruit 1,596 participants for each study arm. Coordinators at intervention sites will facilitate continuity of care for bone health, and arrange fall prevention programs including physical exercise. The intervention teams include medical bone specialists, primary care physicians, pharmacists, nurses, rehabilitation clinicians, and community program organizers. The primary outcome of this study is the incidence of secondary fragility fractures within an 18-month follow-up period. Secondary outcomes include initiation and compliance with bone health medication; time to first fall and number of clinically significant falls; fall-related hospitalization and mortality; physical activity; quality of life; fragility fracture-related costs; admission to a long term care facility; participants’ perceptions of care integration, expectations and satisfaction with the program; and participants’ compliance with the fall prevention program. Finally, professionals at intervention sites will participate in focus groups to identify barriers and facilitating factors for the integrated

    2016-09-01

    Full Text Available Background: Unilateral eye elongation with resultant axial myopia has been reported to occur secondary to visual deprivation from birth or early childhood. Acquired axial length elongation secondary to visual deprivation in adults has rarely been reported. Aim: To report acquired axial myopia in adults with visual deprivation due to long-standing unilateral traumatic cataract. Methods: Eleven consecutive adult patients who presented for cataract surgery with unilateral, long-standing, mature, traumatic cataracts and an interocular axial length difference of more than 1 mm were studied. Patients with a post-operative best corrected visual acuity (BCVA of < 6/12 were excluded to rule out possible pre-existing anisometropic amblyopia. Results: Of the 11 patients with significant interocular axial length difference, 5 patients were excluded on the basis of possible pre-existing amblyopia. The remaining 6 patients had final BCVA of 6/12 or better. The median length of the cataractous eyes was 2.83 mm longer than the fellow eyes (range 1.12 mm – 3.52 mm. The intraocular lens power required for emmetropia was 6.8 dioptres (range 3.5 dioptres – 11.5 dioptres less in the cataractous eyes. A refractive outcome within 1 dioptre of the target refraction was achieved in all patients. The median delay between ocular trauma and cataract surgery was 20 years (range 8–24 years. Conclusion: Significant unilateral axial length elongation may occur in adults with longstanding traumatic cataracts and visual deprivation. A potential correlation may exist between delay to surgery and degree of axial length difference. This rare phenomenon must be considered when determining intraocular lens power to avoid post-operative refractive surprises.

    Full Text Available A brief overview of the prevention part of the long-term Erlangen-Nuremberg Development and Prevention Study, which combines a prospective longitudinal and experimental design. Findings up to five years after intervention are reported. From a sample of 609 families with kindergarten children, subgroups participated in the universal prevention program EFFEKT (child social skills training, a parent training and a combination of both or were assigned to equivalent control groups. The short-term evaluation showed significant effects in mediating constructs (social problem solving and parenting behavior and in educators’ratings of children’s social behavior. In a follow-up after two to three years, school report cards showed fewer children with multiple behavior problems. In a further follow up after four to five years program children reported fewer externalizing and internalizing problems than the control group. There were no significant effects in the mothers’ reports on their children’s behavior. Most significant effect sizes ranged between d = 0.20 and d = 0.40. The findings suggest various positive long-term effects of the intervention. However, one need to be cautious with regard to over-generalizing the positive findings, because effectsizes vary over time and the positive findings could not be replicated in all investigated variables.

    This study assessed the preparedness of school health personnel to develop and deliver HIV/AIDS prevention education programmes for young people in China. A survey of 653 personnel working in secondary schools in 14 cities was conducted. More than 90% had basic knowledge of ways in which HIV can be transmitted, but knowledge of ways in which the virus is not transmitted needs improvement. Substantial numbers of teachers were not sure whether there was an effective preventive vaccine (42%) or did not know whether AIDS was a curable illness or not (32%). The great majority approved of AIDS prevention programmes in universities (98%) and secondary schools (91%), although fewer (58%) agreed that the topic was appropriate for primary schools. Currently, most classroom activities focuses on teaching facts about HIV/AIDS transmission, while less than half are taught about HIV/AIDS related discrimination and life skills to reduce peer pressure. Personnel with some prior training on HIV/ AIDS education (53%) had better factual knowledge, more tolerant attitudes and more confidence in teaching about HIV/AIDS than those without training. The majority of teachers indicated a need for more resource books, audiovisual products, expert guidance, school principal support and dissemination of national AIDS prevention education guidelines to schools.

    To compare the surgical outcomes of simultaneous penetrating keratoplasty and cataract surgery with those of sequential surgery. Thirty-nine eyes of 39 patients scheduled for simultaneous keratoplasty and cataract surgery and 23 eyes of 23 patients scheduled for sequential keratoplasty and secondary phacoemulsification surgery were recruited. Refractive error, regular and irregular corneal astigmatism determined by Fourier analysis, and endothelial cell loss were studied at 1 week and 3, 6, and 12 months after combined surgery in the simultaneous surgery group or after subsequent phacoemulsification surgery in the sequential surgery group. At 3 and more months after surgery, mean refractive error was significantly greater in the simultaneous surgery group than in the sequential surgery group, although no difference was seen at 1 week. The refractive error at 12 months was within 2 D of that targeted in 15 eyes (39%) in the simultaneous surgery group and within 2 D in 16 eyes (70%) in the sequential surgery group; the incidence was significantly greater in the sequential group (P = 0.0344). The regular and irregular astigmatism was not significantly different between the groups at 3 and more months after surgery. No significant difference was also found in the percentage of endothelial cell loss between the groups. Although corneal astigmatism and endothelial cell loss were not different, refractive error from target refraction was greater after simultaneous keratoplasty and cataract surgery than after sequential surgery, indicating a better outcome after sequential surgery than after simultaneous surgery.

    Cataract is a major cause of visual impairment among elderly. Cataract surgery improves visual afferencies and can have an impact on balance. The present study assessed the impact of cataract surgery upon balance and autonomy in elderly. We realized clinical examinations and objective tests the day before surgery and 2-months later. The initial cohort consisted of 66 patients that had to undergo a cataract surgery. Their mean age was 79 +/- 0.5. For logistic reasons, only 33 patients have been completely evaluated before and after surgery. Each patient underwent a history and examination that have assessed autonomy, walking, visual and then cochleo-vestibular functions including bone vibratory test and dynamic computerized posturography (Equitest). After 2 months, cataract surgery had no incidence on balance. The fear of falling has stayed the same whereas the number of falls has been noticeably reduced by surgery. The overall score of Equitest has shown an increase in visual dependence after surgery. Although cataract surgery has no incidence on autonomy, it may improve the quality of life among older people by leisure activities recovery. An early physical rehabilitation facilitated by visual improvement after surgery can also prevent visual dependence and autonomy loss. We recommend vestibular rehabilitation in elderly with major visual dependence.

    With Parkinson's disease (PD) prevalence rates steadily increasing and long-term adherence to regular physical activity and exercise often difficult to achieve, it is imperative to investigate factors promoting adherence to secondary prevention programs (SPP) that help limit the progression of motor and nonmotor signs and symptoms of the disease. Caring interactions between patients and their rehabilitation team may be particularly germane to individuals with PD, given the physical and psychosocial issues that often accompany this disease (eg, loss of physical function, depression, apathy, and cognitive impairments). Considering this reasoning, the purpose of the present study was twofold: (1) to gain a better understanding of the nature of caring in an SPP setting from a patient perspective and (2) to discover what implications, if any, caring has on relevant patient-centered behaviors such as effort and adherence to SPPs. Ten individuals with PD were recruited. In-depth, qualitative interviews were performed using a semistructured interview guide. Inductive content analysis was used to identify themes representing participants' experiences of caring in the SPP setting. Six themes emerged from the data analysis. The first 4 themes described how rehabilitation providers fostered caring in the SPP setting: showing interest, creating a supportive atmosphere, benevolence, and paying attention. Participants described instances when rehabilitation providers (physical therapy assistants, physical therapy students, and exercise specialists) showed interest by asking personal questions and remembering personal information. A supportive environment was facilitated by making participants feel supported, welcomed, and valued. Benevolence was apparent when rehabilitation providers demonstrated kindness and approached their work as "more than just a job." Finally, the importance of feeling that rehabilitation providers "paid attention" to patients by giving them undivided

    Full Text Available Cataract with high myopia is research priority associated with the large amount of high myopia patients. The unaided visual acuity and the best-corrected visual acuity are partial for the visual acuity of the patients with cataract. The mechanism and clinical significance of modern visual function measurements associated with cataract and high myopia, including accommodation and convergence, stereoscopic vision, contrast sensitivity, have been introduced. These measurements could be of great value in early diagnosis of cataract, assessment of surgical indication, customized intraocular lens(IOLselection and evaluation of visual performance after IOL implantation. They could also be helpful to the analysis of postoperative impaired visual function and its management. Having an adequate understanding of the contents and significance of visual function was helpful to the improvement of cataract surgery techniques and postoperative visual acuity.

    significant, was probably too small to be of clinical relevance. The quality of the evidence was rated as high for intraoperative pain and moderate for pain at 24 hours. We did find differences in pain during administration of local anaesthetic (low level of evidence), and indications that surgeon satisfaction (low level of evidence) and participant satisfaction (moderate level of evidence) were less with topical anaesthesia. There was not enough evidence to say that one technique would result in a higher or lower incidence of intraoperative complications compared with the other. Both topical anaesthesia and sub-Tenon's anaesthesia are accepted and safe methods of providing anaesthesia for cataract surgery. An acceptable degree of intraoperative discomfort has to be expected with either of these techniques. Randomized controlled trials on the effects of various strategies to prevent intraoperative pain during cataract surgery could prove useful.

    Human service professionals are concerned with the intervention and empowerment of vulnerable social populations. The human service industry is laden with employment-related stressors and emotionally demanding interactions, which can lead to deleterious effects, such as burnout and secondary traumatic stress. Little attention has been given to developing knowledge of what might enable human service workers to persist and thrive. Cultivating and sustaining resilience can buffer the impact of occupational stressors on human service professionals. One of the psychological factors associated with cultivating resilience is mindfulness. The aim of this current research is to improve our understanding of the relationship between resilience, mindfulness, burnout, secondary traumatic stress, and psychological distress among human service professionals. The current study surveyed 133 human service professionals working in the fields of psychology, social work, counseling, youth and foster care work to explore the predictive relationship between resilience, mindfulness, and psychological distress. The results showed that higher levels of resilience were a significant predictor of lower levels of psychological distress, burnout and secondary traumatic stress. In addition, higher levels of mindfulness were a significant predictor of lower levels of psychological distress and burnout. The findings suggest that cultivating resilience and mindfulness in human service professionals may assist in preventing psychological distress burnout and secondary traumatic stress. Limitations of this study are discussed together with implications for future research.

    Current recommendations do not specifically address the optimal blood pressure (BP) reduction for secondary stroke prevention in patients with previous cerebrovascular events. We conducted a systematic review and metaregression analysis on the association of BP reduction with recurrent stroke and cardiovascular events using data from randomized controlled clinical trials of secondary stroke prevention. For all reported events during each eligible study period, we calculated the corresponding risk ratios to express the comparison of event occurrence risk between patients randomized to antihypertensive treatment and those randomized to placebo. On the basis of the reported BP values, we performed univariate metaregression analyses according to the achieved BP values under the random-effects model (Method of Moments) for those adverse events reported in ≥10 total subgroups of included randomized controlled clinical trials. In pairwise meta-analyses, antihypertensive treatment lowered the risk for recurrent stroke (risk ratio, 0.73; 95% confidence interval, 0.62-0.87; Psecondary stroke prevention. © 2016 American Heart Association, Inc.

    Schools and kindergartens are particularly suitable for the implementation of violence prevention programs. Many German schools and kindergartens have securely established the violence prevention curriculum Faustlos. The Faustlos programs for kindergartens and elementary schools are now complemented with the version for middle schools. As the kindergarten- and elementary school versions the middle school program too focuses on the theoretically profound, age group-tailored promotion of empathy, impulse control and anger management. These dimensions are subdivided into the five themes "understanding the problem" "training for empathy"; "anger management", "problem solving" and "applying skills" and taught stepwise, highly structured and based on several video sequences in 31 lessons. US-American evaluation studies proof the effectiveness and the violence prevention potential of the program. With the curriculum for middle schools a comprehensive Faustlos program package is now made available to sustainably promote core violence prevention competences of children and adolescents on a developmentally appropriate level and with a consistent didactic approach.

    To establish current physiotherapy practice in the secondary management of falls and fragility fractures compared with national guidance. Web-based national clinical audit. Acute trusts (n=157) and primary care trusts (n=146) in England, Wales and Northern Ireland. Data were collected on 5642 patients with non-hip fragility fractures and 3184 patients with a hip fracture. Those patients who were bedbound or who declined assessment or rehabilitation were excluded from the analysis. Results indicate that of those with non-hip fractures, 28% received a gait and balance assessment, 22% participated in an exercise programme, and 3% were shown how to get up from the floor. For those with a hip fracture, the results were 68%, 44% and 7%, respectively. Physiotherapists have a significant role to play in the secondary prevention of falls and fractures. However, along with managers and professional bodies, more must be done to ensure that clinical practice reflects the evidence base and professional standards.

  10. Secondary Prevention of Esophageal Squamous Cell Carcinoma in Areas Where Smoking, Alcohol, and Betel Quid Chewing are Prevalent

    Chen-Shuan Chung

    2010-06-01

    Full Text Available Esophageal cancer is ranked as the sixth most common cause of cancer death worldwide and has a substantial effect on public health. In contrast to adenocarcinoma arising from Barrett's esophagus in Western countries, the major disease phenotype in the Asia-Pacific region is esophageal squamous cell carcinoma which is attributed to the prevalence of smoking, alcohol, and betel quid chewing. Despite a multidisciplinary approach to treating esophageal cancer, the outcome remains poor. Moreover, field cancerization reveals that esophageal squamous cell carcinoma is closely linked with the development of head and neck cancers that further sub-optimize the treatment of patients. Therefore, preventive strategies are of paramount importance to improve the prognosis of this dismal disease. Since obstacles exist for primary prevention via risk factor elimination, the current rationale for esophageal cancer prevention is to identify high-risk groups at earlier stages of the disease, and encourage them to get a confirmatory diagnosis, prompt treatment, and intensive surveillance for secondary prevention. Novel biomarkers for identifying specific at-risk populations are under extensive investigation. Advances in image-enhanced endoscopy do not just substantially improve our ability to identify small precancerous or cancerous foci, but can also accurately predict their invasiveness. Research input from the basic sciences should be translated into preventive measures in order to decrease the disease burden of esophageal cancer.

    Human eyes are most sophisticated organ, with perfect and interrelated subsystems such as retina, pupil, iris, cornea, lens and optic nerve. The eye disorder such as cataract is a major health problem in the old age. Cataract is formed by clouding of lens, which is painless and developed slowly over a long period. Cataract will slowly diminish the vision leading to the blindness. At an average age of 65, it is most common and one third of the people of this age in world have cataract in one or both the eyes. A system for detection of the cataract and to test for the efficacy of the post-cataract surgery using optical images is proposed using artificial intelligence techniques. Images processing and Fuzzy K-means clustering algorithm is applied on the raw optical images to detect the features specific to three classes to be classified. Then the backpropagation algorithm (BPA) was used for the classification. In this work, we have used 140 optical image belonging to the three classes. The ANN classifier showed an average rate of 93.3% in detecting normal, cataract and post cataract optical images. The system proposed exhibited 98% sensitivity and 100% specificity, which indicates that the results are clinically significant. This system can also be used to test the efficacy of the cataract operation by testing the post-cataract surgery optical images.

    Iodine has been recognized as an effective bactericide since the 1800's, and povidone-iodine (PI) solution has been applied to the ocular surface and periocular skin since the 1980's to prevent endophthalmitis in cataract surgery. In vitro, PI solution kills bacteria very quickly at dilute concentrations (0.05-1.0%). In many instances, PI kills bacteria more quickly at these dilute concentrations than more conventional (5%-10%) concentrations. This is due to greater availability of diatomic free iodine in dilute solution, the bactericidal component of PI. The toxicity of PI, both in vitro and clinically has been shown to be related to concentration. Current American Academy of Ophthalmology (AAO) and the European Society of Cataract and Refractive Surgeons (ESCRS) recommendations regarding PI use suggest using 5% PI prior to surgery. An alternative dosing strategy uses dilute PI repetitively throughout cataract surgery (0.25% every thirty seconds). We review the povidone-iodine literature with attention to basic science and use of dilute PI. Copyright © 2018 Elsevier Inc. All rights reserved.

    Latin America has witnessed a marked increase in cardiovascular (CV) disease, the leading cause of death in many countries. The benefits of lipid-lowering therapy to reduce CV-related events are widely accepted. Clinical evidence suggests that rosuvastatin is associated with slightly greater reductions in low-density lipoprotein cholesterol levels than is atorvastatin at comparable doses. Rosuvastatin, however, is often priced at a premium. Our objective was to examine the cost-effectiveness of using atorvastatin versus rosuvastatin in reducing CV events in Brazil and Colombia using real-world prices. A global Markov cohort model of primary and secondary CV prevention was developed and adapted to Brazilian and Colombian settings. The risks and costs of major CV events and efficacy, adherence, and costs of statins were considered. Total gains in life-years, quality-adjusted life-years, major CV events avoided, and costs over the lifetime horizon were estimated. Several dose comparisons were considered. In the Colombian analyses, differences in drug costs between therapies were considerable while outcomes were similar. The incremental cost per quality-adjusted life-year gained for rosuvastatin versus atorvastatin was more than $700,000 and $200,000 in primary and secondary prevention, respectively. Brazilian analyses found lower incremental cost-effectiveness ratios for rosuvastatin at some dose comparisons due to similar pricing between statins. Sensitivity analyses revealed that changes in treatment efficacy and adherence had the largest impact on results. In primary and secondary CV prevention, the efficacy advantage of rosuvastatin was minimal, while its acquisition cost was higher, particularly in Colombia. The incremental cost-effectiveness ratios were, therefore, generally in favor of atorvastatin being the cost-effective option.

    Ischaemic heart disease (IHD) is the most common cause of death worldwide. To determine the long-term impact of organisational interventions for secondary prevention of IHD. Systematic review and meta-analysis of studies from CENTRAL, MEDLINE(®), Embase, and CINAHL published January 2007 to January 2013. Searches were conducted for randomised controlled trials of patients with established IHD, with long-term follow-up, of cardiac secondary prevention programmes targeting organisational change in primary care or community settings. A random-effects model was used and risk ratios were calculated. Five studies were included with 4005 participants. Meta-analysis of four studies with mortality data at 4.7-6 years showed that organisational interventions were associated with approximately 20% reduced mortality, with a risk ratio (RR) for all-cause mortality of 0.79 (95% confidence interval [CI] = 0.66 to 0.93), and a RR for cardiac-related mortality of 0.74 (95% CI = 0.58 to 0.94). Two studies reported mortality data at 10 years. Analysis of these data showed no significant differences between groups. There were insufficient data to conduct a meta-analysis on the effect of interventions on hospital admissions. Additional analyses showed no significant association between organisational interventions and risk factor management or appropriate prescribing at 4.7-6 years. Cardiac secondary prevention programmes targeting organisational change are associated with a reduced risk of death for at least 4-6 years. There is insufficient evidence to conclude whether this beneficial effect is maintained indefinitely. © British Journal of General Practice 2015.

    Full Text Available Two 8- and 9-year-old brothers were referred to the Pediatric Oncology Unit, Perugia General Hospital, because of hyperferritinemia. Both had a history of bilateral cataract and epilepsy. Genetic investigation revealed two distinct mutations in iron haemostasis genes; homozygosity for the HFE gene H63D mutation in the younger and heterozygosity in the elder. Both displayed heterozygosity for C33T mutation in the ferritin light chain iron response element. A 7-year-old boy from another family was referred to our unit because of hyperferritinemia. Genetic analyses did not reveal HFE gene mutations. Family history showed that his mother was also affected by hyperferritinemia without HFE gene mutations. Magnetic resonance imaging in the mother was positive for iron overload in the spleen. Cataract was diagnosed in mother and child. Further genetic investigation revealed the C29G mutation of the ferritin light chain iron response element. C33T and C29G mutations in the ferritin light chain iron response element underlie the Hereditary Hyperferritinemia-Cataract Syndrome (HHCS. The HFE gene H63D mutation underlies Hereditary Haemochromatosis (HH, which needs treatment to prevent organ damages by iron overload. HHCS was definitively diagnosed in all three children. HHCS is an autosomal dominant disease characterized by increased L-ferritin production. L-Ferritin aggregates accumulate preferentially in the lens, provoking bilateral cataract since childhood, as unique known organ damage. Epilepsy in one case and the spleen iron overload in another could suggest the misleading diagnosis of HH. Consequently, the differential diagnosis between alterations of iron storage system was essential, particularly in children, and required further genetic investigation.

    Since about 10 years, problems of secondary circuit corrosion have raised for PWR plant management. The watch staff can't be asked the physicochemical knowledge requested for a proper interpretation of the various probes outputs. So an expert-system has been performed to help the identification of dangerous situation from a corrosion point of view, and immediately start the PWR managing action. This software has been successfully tested and validated. (D.L.). 5 figs., 4 photos

    In a retrospective cohort study, we tested the hypothesis that when prescribing hydroxyurea (HU) to children with sickle cell anemia (SCA) to prevent vaso-occlusive events, there will be a secondary benefit of maintaining low transcranial Doppler (TCD) velocity, measured by imaging technique (TCDi). HU was prescribed for 90.9% (110 of 120) of children with SCA ≥5 years of age and followed for a median of 4.4 years, with 70% (n = 77) receiving at least one TCDi evaluation after starting HU. No child prescribed HU had a conditional or abnormal TCDi measurement. HU initiation for disease severity prevention decreases the prevalence of abnormal TCDi velocities. © 2016 Wiley Periodicals, Inc.

    Full Text Available The prevalence of blindness among children in different regions varies from 0.2/1000 children to over 1.5/1000 children with a global figure estimated at 0.7/1000. This means that there are an estimated 1.4 million blind children worldwide.1 The proportion of blindness in children due to cataract varies considerably between regions from 10%-30% with a global average estimated at 14%, giving 190,000 children blind from cataract. 2 While the magnitude of childhood cataracts varies from place to place, it is a priority within all blindness control programmes for children. Children who are blind have to overcome a lifetime of emotional, social and economic difficulties which affect the child, the family and society.3 Loss of vision in children influences their education, employment and social life. The numbers blind with cataract do not reflect the years of disability and lost quality of life. Childhood blindness is second only to adult cataract as a cause of blind-person years. Approximately 70 million blind-person years are caused by childhood blindness of which about 10 million blind-person years (14% is due to childhood cataract. Timely recognition and intervention can eliminate blind-years due to childhood cataract, as the condition is treatable.

    Full Text Available Heart failure is currently a real public health problem due to the extremely high morbidity and mortality of this disease. In this context, cardiovascular prevention measures should be implemented as early as possible. In addition to classic prevention measures, a number of extremely important specific recommendations should be considered: informing patients about their underlying disease, identifying the cardiovascular and non-cardiovascular factors that have led to cardiac decompensation, reducing daily salt consumption, monitoring body weight, forbidding smoking and recreational substances, conducting a regular exercise program under supervision, and increasing adherence to treatment.

    Krause, James S.; Saunders, Lee L.; DiPiro, Nicole D.; Reed, Karla S.

    2013-01-01

    Background: To successfully prevent secondary health conditions (SHCs) and promote longevity after spinal cord injury (SCI), we must first understand the risk factors precipitating their occurrence and develop strategies to address these risk factors. Conceptual models may aid in identifying the nature of SHCs and guide research, clinical practice, and the development of prevention strategies. Objective: Our purpose is to review and refine an existing theoretical risk and prevention model (TRPM) as a means of classifying risk and protective factors for SHCs and mortality after SCI and for identifying points of intervention. Methods: We describe conceptual work within the field of SCI research and SHCs, including a description of the TRPM, a review of research using the TRPM, and conceptual enhancements to the TRPM based on previous research. Conclusions: The enhanced TRPM directs research to the timing and chronicity of the SHCs and their relationship with overall health and physiologic decline. Future research should identify differences in the nature of SHCs, the extent to which they relate to risk and protective factors, and the degree to which they may be prevented with appropriate research-based strategies.

    This study explored experiences and contexts of HIV risk and prevention among HIV-positive kothi-identified men in Chennai, India. In-depth, semi-structured interviews were conducted with 10 HIV-positive men and three service providers, recruited using purposive sampling. Interviews were audio-taped, transcribed in Tamil and translated into English. Data were analysed using a narrative thematic approach and constant comparative method. Misconceptions about HIV transmission; cultural taboos around discussing sexual behaviour and HIV; stigma related to same-sex behaviour; harassment; and the criminalization of consensual sex between men present formidable challenges to HIV prevention. Frank and open discussion about male-to-male sexual behaviour and living with HIV, which may support health and HIV prevention, may be dangerous in the context of pervasive risks due to stigmatization, violence and criminalization. Instead, culturally appropriate, multi-level interventions developed in collaboration with community stakeholders are needed to support HIV prevention among kothi-identified men in South India.

    Ischemic heart disease remains a leading cause of death in Spain. According to the American Heart Association/American College of Cardiology (AHA/ACC) and European national societies, secondary prevention for these patients consists of control of major cardiovascular risk factors (CVRF) and suitable lifestyle habits. To determine the degree of control of CVRF in the Aragonese population in secondary prevention. Cross-sectional study of a sample of 705 patients of Aragon who had suffered a cardiac event, selected opportunistically in consultations of family physicians participating in the 3 provinces of Aragon. The study was conducted in the second half of 2012. To measure the degree of control of different FRVC and lifestyle habits in this population. Anthropometric, different cardiovascular risk factors, treatment and lifestyle. 58% of men and 52% of women met criteria for monitoring of measured variables. The best result was obtained with smoking cessation and the worst with BMI. Hypertension, Dyslipidemia and Diabetes Mellitus achieve poor control results. The results show that the degree of control of CVRF is still low, especially in variables such as dyslipidemia and Diabetes Mellitus. Only 16.5% of control patients met criteria given the pharmacologically-modifiable cardiovascular risk factors. Copyright © 2015 SEHLELHA. Published by Elsevier España, S.L.U. All rights reserved.

    To enhance positive attitude and life skills on gender roles to prevent physical and sexual violence. A whole school-based participatory learning program using a quasi-experimental study with pre and post test design was conducted among 2 schools during June-September, 2005. The experimental group, were 134 students in a primary school and 179 students in a secondary school. While the control group, were 122 students in a primary school and 95 students in a secondary school. Means score of attitude toward gender roles before implementation in the experimental group was significantly lower than the control group (p 0.05). Means paired different score (after-before) between the two groups was significantly different (p = 0.002). A whole school-based program on gender roles and violence prevention is suitable for youths and should be merged as school curricula and expanded as a nationwide program at all level of education. Gender equity should be taught at an early childhood. Parental involvement in school-based activities should be negotiated.

    This study aims at assessing the gap in secondary fracture prevention at a regional general hospital setting in Singapore. Male patients have significantly lower rate of being investigated and treated for osteoporosis than their female counterparts. Vitamin D deficiency is prevalent in our population. Secondary fracture prevention services are not routine in Singapore; we seek to assess the treatment gap that exists in the lack of diagnosis and treatment of osteoporosis in fragility fracture patients. We performed a retrospective analysis of all admissions for fragility fractures between December 2013 and December 2014. Demographic data, rates of BMD performance, serum vitamin D investigation and calcium and vitamin D supplementation as well as antiresorptive initiation 1 year post admission were analysed. There were 125 fragility fractures in patients below 65 and 615 fractures in older patients. There was a slightly higher proportion of males in the younger population, whereas females predominated in the older population. Median vitamin D levels were low in both younger (19.1 μg/L) and older (22.0 μg/L) groups, but supplementation was lower in younger patients (4.8 versus 16.6%, p = 0.003). Rate of BMD performance was lower in younger patients (34.4 versus 64.6%, p Singapore. Male osteoporosis remains inadequately investigated and treated in both age groups.

    Secondary prevention programmes can be effective in reducing morbidity and mortality from coronary heart disease (CHD). In particular, UK guidelines, including those from the Department of Health, emphasize physical activity. However, the effects of secondary prevention programmes with an exercise component are moderate and uptake is highly variable. In order to explore patients' experiences of a pre-exercise screening and health coaching programme (involving one-to-one consultations to support exercise behaviour change), semi-structured telephone interviews were undertaken with 84 CHD patients recruited from primary care. The interviews focused on patients' experiences of the intervention including referral and any recommendations for improvement. A thematic analysis of transcribed interviews showed that the majority of patients were positive about referral. However, patients also identified a number of barriers to attending and completing the programme, including a belief they were sufficiently active already, the existence of other health problems, feeling unsupported in community-based exercise classes and competing demands. Our findings highlight important issues around the choice of an appropriate point of intervention for programmes of this kind as well as the importance of appropriate patient selection, suggesting that the effectiveness of health coaching may be under-reported as a result of including patients who are not yet ready to change their behaviours.

    Secondary pharmaceutical measures are effective in all age groups for the prevention of osteoporotic fractures. This prospective study determines the demographics of 566 consecutive osteoporotic hip fractures presenting to a Level 1 Trauma Center. We examine the efficacy of simple treatment recommendations for pharmaceutical treatment of osteoporosis and the factors determining general practitioner and patient compliance with these recommendations in a community setting. One out of four patients (24.5%) had sustained a previous fragility fracture. Mean age was 80 years. Twenty five percent were resident in a nursing home and only 10% were taking anti-resorptive therapy preoperatively. In hospital mortality was 6%, and 39% of recruited patients were dead at 12 months. By this time more than half the survivors were resident in a nursing home. The compliance with anti-resorptive therapy had increased to over 70% consequent to our simple recommendations. Significant differences in GP and patient compliance were observed between nursing home and own residence dwellers. This study demonstrates the efficacy of a simple clinical practice intervention in increasing patient and GP compliance with secondary fracture prevention measures. We also discuss many of the confounding issues determining this compliance.

    Full Text Available Background: Coronary heart disease (CHD is a common and potentially fatal malady with a life time prevalence of over 20%. For Germany, the mortality attributable to chronic ischemic heart disease or acute myocardial infarction is estimated at 140,000 deaths per year. An association between prognosis of CHD and lifestyle risk factors has been consistently shown. To positively influence lifestyle risk factors in patients with CHD, non-pharmaceutical secondary prevention strategies are frequently recommended and implemented. Objectives: The aim of this HTA (HTA = Health Technology Assessment is to summarise the current literature on strategies for non-pharmaceutical secondary prevention in patients with CHD and to evaluate their medical effectiveness/efficacy and cost-effectiveness as well as the ethical, social and legal implications. In addition, this report aims to compare the effectiveness and efficacy of different intervention components and to evaluate the generalisability with regard to the German context. Methods: Relevant publications were identified by means of a structured search of databases accessed through the German Institute of Medical Documentation and Information (DIMDI. In addition, a manual search of identified reference lists was conducted. The present report includes German and English literature published between January 2003 and September 2008 targeting adults with CHD. The methodological quality of included studies was assessed according to pre-defined quality criteria, based on the criteria of evidence based medicine. Results: Among 9,074 publications 43 medical publications met the inclusion criteria. Overall study quality is satisfactory, but only half the studies report overall mortality or cardiac mortality as an outcome, while the remaining studies report less reliable outcome parameters. The follow-up duration varies between twelve and 120 months. Although overall effectiveness of non-pharmaceutical secondary

    Compared to other mental illnesses, bipolar disorder is associated with a disproportionately high rate of substance use disorders (SUDs), and the co-occurrence is associated with significant morbidity and mortality. Early diagnosis of primary bipolar disorder may provide opportunities for SUD prevention, but little is known about the risk factors for secondary SUD among individuals with bipolar disorder. The purposes of this study were to describe the population of people with childhood and adolescent-onset primary bipolar disorder, and to identify risk factors for secondary SUD in this population. Using data collected from the National Comorbidity Survey Replication study, we identified 158 individuals with childhood-onset (adolescent-onset (13-18 years) primary bipolar disorder (I, II or subthreshold). Survival analysis was used to identify risk factors for SUD. Compared to adolescent-onset, people with childhood-onset bipolar disorder had increased likelihoods of attention deficit hyperactivity disorder (ADHD) (adjusted odds ratio=2.81) and suicide attempt (aOR=3.61). Males were more likely than females to develop SUD, and did so at a faster rate. Hazard ratios of risk factors for SUD were: lifetime oppositional defiant disorder (2.048), any lifetime anxiety disorder (3.077), adolescent-onset bipolar disorder (1.653), and suicide attempt (15.424). SUD was not predicted by bipolar disorder type, family history of bipolar disorder, hospitalization for a mood episode, ADHD or conduct disorder. As clinicians struggle to help individuals with bipolar disorder, this study provides information that might be useful in identifying individuals at higher risk for SUD. Future research can examine whether targeting these risk factors may help prevent secondary SUD. Published by Elsevier Inc.

    Exogenous administration of melatonin has been demonstrated to down-regulate inflammatory responses and attenuate organ damage in various models. However, the salutary effect of melatonin against secondary intra-abdominal hypertension (IAH) remains unclear. This study sought to test the influence of melatonin on secondary IAH in a pathophysiological rat model and the underlying mechanisms involved. Before resuscitation, male rats underwent a combination of induced portal hypertension, applying an abdominal restraint device, and hemorrhaging to mean arterial pressure (MAP) of 40mmHg for 2h. After blood reinfusion, the rats were treated with lactated Ringer solution (LR) (30mL/h), melatonin (50mg/kg) +LR, and SB-203580 (10μmol/kg)+LR. LR was continuously infused for 6h. MAP, the inferior vena cava pressure and urine output were monitored. Histopathological examination, immunofluorescence of tight junction proteins, and transmission electron microscopy were administered. Intestinal permeability, myeloperoxidase activity, malondialdehyde, glutathione peroxidase, and levels of TNF-a, IL-2, and IL-6, were assessed. The expression of extracellular signal-regulated kinase, p38, c-Jun NH2-terminal kinase, translocation of nuclear factor kappa B subunit, signal transducers and activators of transcription and tight junction proteins were detected by Western blot. We found that melatonin inhibited the inflammatory responses, decreased expression of p38 MAPK, attenuated intestinal injury, and prevented secondary IAH. Moreover, administration of SB203580 abolished the increase in p38 MAPK and also attenuated intestinal injury. These data indicate that melatonin exerts a protective effect in intestine in secondary IAH primarily by attenuating the inflammatory responses which are in part attributable to p38 MAPK inhibition.

    In order to control the spread of rubella and reduce the risk for congenital rubella syndrome, an additional rubella vaccination program was set up for all secondary school students since 2008 in Zhejiang, China. We conducted a descriptive analysis of rubella incidence among different age groups from 2005 to 2015 and a serosurvey of female subjects aged 15-39 years to understand the possible effects of this immunization program. The average annual rubella incidence rate had decreased from 15.86 per 100,000 population (2005-2007) to 0.75 per 100,000 population (2013-2015) in Zhejiang. The decrease in the rate of rubella incidence in girls aged 15-19 years was more accelerated (from 138.30 to 0.34 per 100,000) than in the total population during 2008-2015 (from 32.20 to 0.46 per 100,000). Of 1225 female subjects in the serosurvey, 256 (20.9%) were not immune to rubella. The proportion of subjects immune to rubella was significantly different among different age groups (Wald χ2 = 22.19, p = 0.000), and subjects aged 15-19 years old had the highest immunity (88.0%). Rubella antibody levels were significantly lower in women aged 25-30 years with 26.7% of them not immune, followed by the group aged 20-24 years (25.0%) and 30-35 years (24.5%). Rubella vaccine included in the Expanded Program on Immunization together with vaccination activities for secondary school students can help in rubella control, particularly in targeted age groups in the program. Seroprevalence of antibodies to the rubella virus amongst the female population within childbearing age in Zhejiang, China, is still too low to provide immunity. In addition to vaccination programs in the secondary schools, rubella vaccination should also be encouraged in women of childbearing age, which can be done effectively combined with pre-marital examination in China.

    To report a series of eyes that developed malignant glaucoma after cataract surgery. Private academic practice, Toronto, Ontario, Canada. Retrospective case series. Eyes that developed malignant glaucoma after cataract surgery were treated with medical therapy. This was followed by laser iridozonulohyaloidotomy, anterior chamber reformation and intraocular lens (IOL) pushback, and finally with surgical iridozonulohyaloidovitrectomy if all other measures were unsuccessful. Refraction, intraocular pressure (IOP), gonioscopy, and anterior chamber depth (ACD) by anterior segment optical coherence tomography were analyzed before treatment and after treatment. The study evaluated 20 eyes of 18 female patients aged 44 to 86 years. Preoperatively, the mean refraction was +3.11 diopters (D) ± 2.89 (SD), the mean axial length was 21.30 ± 1.40 mm, and all eyes had narrow or closed angles. Malignant glaucoma was diagnosed a mean of 5.8 ± 7.1 weeks postoperatively. At diagnosis, the mean refraction was -2.15 ± 2.95 D; the mean ACD, 2.49 ± 0.72 mm; and the mean IOP, 28.3 ± 10.8 mm Hg on a mean of 1.3 ± 1.6 medications. Two eyes responded to cycloplegia, 7 to laser iridozonulohyaloidotomy, and 6 to anterior chamber reformation-IOL pushback; 5 eyes required vitrectomy. Posttreatment, the mean refraction was -0.56 ± 1.07 D; the mean ACD, 3.30 ± 0.50 mm; and the mean IOP, 14.4 ± 4.60 mm Hg on a mean of 1.2 ± 1.4 medications. Cycloplegia was discontinued in 17 eyes. Malignant glaucoma can occur after phacoemulsification and presents with myopic surprise, anterior chamber shallowing and, possibly, elevated IOP.

    Antiphospholipid syndrome (APS) is an acquired thrombophilia characterized by thrombosis, pregnancy morbidity, and the presence of characteristic antibodies. Current therapy for patients having APS with a history of thrombosis necessitates anticoagulation with the vitamin K antagonist warfarin, a challenging drug to manage. Apixaban, approved for the treatment and prevention of venous thrombosis with a low rate of bleeding observed, has never been studied among patients with APS. We report study rationale and design of Apixaban for the Secondary Prevention of Thrombosis Among Patients With Antiphospholipid Syndrome (ASTRO-APS), a prospective randomized open-label blinded event pilot study that will randomize patients with a clinical diagnosis of APS receiving therapeutic anticoagulation to either adjusted-dose warfarin or apixaban 2.5 mg twice a day. We aim to report our ability to identify, recruit, randomize, and retain patients with APS randomized to apixaban compared with warfarin. We will report clinically important outcomes of thrombosis and bleeding. All clinical outcomes will be adjudicated by a panel blinded to the treatment arm. A unique aspect of this study is the enrollment of patients with an established clinical diagnosis of APS. Also unique is our use of electronic medical record interrogation techniques to identify patients who would likely meet our inclusion criteria and use of an electronic portal for follow-up visit data capture. ASTRO-APS will be the largest prospective study to date comparing a direct oral anticoagulant with warfarin among patients with APS for the secondary prevention of thrombosis. Our inclusion criteria assure that outcomes obtained will be clinically applicable to the routine management of patients with APS receiving indefinite anticoagulation. © The Author(s) 2015.

  8. Cataract Surgery in Anterior Megalophthalmos: A Review

    2015-01-01

    Anterior megalophthalmos is characterized by megalocornea associated with a very broad anterior chamber and ciliary ring elongation. It is also called X-linked megalocornea. It is accompanied by early development of cataracts, zonular anomalies, and, rarely, vitreoretinal disorders. Subluxation of a cataract can occur in cataract surgery because of zonular weakness. In addition, in most patients, standard intraocular lens (IOL) decentration is a risk because of the enlarged sulcus and capsular bag. These unique circumstances make cataract surgery challenging. To date, several approaches have been developed. Implantation of a retropupillary iris-claw aphakic intraocular lens may be a good option because it is easier than suturing the IOL and can have better and more stable anatomic and visual outcomes, compared to other techniques.

    Investigations demonstrated that oxidative stress plays an important role in injury promotion in cholestatic liver disease. We hypothesized that coffee attenuates cholestasis-induced hepatic necrosis and fibrosis via its antioxidant, anti-inflammatory, and antifibrotic properties. The major aim of this study was to evaluate the hepatoprotective properties of coffee and caffeine in a model of chronic bile duct ligation (BDL) in male Wistar rats. Liver injury was induced by 28-day BDL, and conventional coffee, decaffeinated coffee, or caffeine was administered daily. After treatment, the hepatic oxidative status was estimated by measuring lipid peroxidation, the reduced to oxidized glutathione ratio, and glutathione peroxidase. Fibrosis was assessed by measuring the liver hydroxyproline content. The transforming growth factor-β, connective tissue growth factor, α-smooth muscle actin, collagen 1, and interleukin-10 proteins and mRNAs were measured by Western blot and polymerase chain reaction, respectively. Conventional coffee suppressed most of the changes produced by BDL; however, caffeine showed better antifibrotic effects. Coffee demonstrated antioxidant properties by restoring the redox equilibrium, and it also prevented the elevation of liver enzymes as well as hepatic glycogen depletion. Interestingly, coffee and caffeine administration prevented collagen increases. Western blot assays showed decreased expression levels of transforming growth factor-β, connective tissue growth factor, α-smooth muscle actin, and collagen 1 in the coffee- and caffeine-treated BDL groups. Similarly, coffee decreased the mRNA levels of these proteins. We conclude that coffee prevents liver cirrhosis induced by BDL by attenuating the oxidant processes, blocking hepatic stellate cell activation, and downregulating the main profibrotic molecules involved in extracellular matrix deposition.

    The use of topical corticosteroids following photorefractive keratectomy (PRK) is widespread. The major complications of potent corticosteroids are glaucoma and cataract formation; in order to decrease these complications, 0.1% fluorometholone administration is usually preferred after PRK. We report here a case of lens opacification which was induced by 0.1% fluorometholone administration after PRK in a period of 4 months. To our knowledge, this is the first reported case of 0.1% fluorometholone-induced cataract after PRK.

    Preventing oral-systemic health issues relies on evidence-based interventions across various system-level target groups. Although the use of theory- and evidence-based approaches has been encouraged in developing oral health behavior change programs, the translation of theoretical constructs and principles to behavior change interventions has not been well described. Based on a series of six systematic steps, Intervention Mapping provides a framework for effective decision making with regard to developing, implementing, and evaluating theory- and evidence-informed, system-based behavior change programs. This article describes the application of the Intervention Mapping framework to develop the EAT (evaluating, assessing, and treating) evidence-based intervention with the goal of increasing the capacity of oral health providers to engage in secondary prevention of oral-systemic issues associated with disordered eating behaviors. Examples of data and deliverables for each step are described. In addition, results from evaluation of the intervention via randomized control trial are described, with statistically significant differences observed in behavioral outcomes in the intervention group with effect sizes ranging from r=0.62 to 0.83. These results suggest that intervention mapping, via the six systematic steps, can be useful as a framework for continued development of preventive interventions.

    Intensive risk factor modification significantly improves outcomes for patients with diabetes mellitus and cardiovascular disease. However, the degree to which secondary prevention treatment goals are achieved in international clinical practice is unknown. Attainment of 5 secondary prevention parameters-aspirin use, lipid control (low-density lipoprotein cholesterol diabetes mellitus and known cardiovascular disease at entry into TECOS (Trial Evaluating Cardiovascular Outcomes With Sitagliptin). Logistic regression was used to evaluate the association between individual and regional factors and secondary prevention achievement at baseline. Cox proportional hazards regression analysis was used to determine the association between baseline secondary prevention achievement and cardiovascular death, myocardial infarction, or stroke. Overall, 29.9% of patients with diabetes mellitus and cardiovascular disease achieved all 5 secondary prevention parameters at baseline, although 71.8% achieved at least 4 parameters. North America had the highest proportion (41.2%), whereas Western Europe, Eastern Europe, and Latin America had proportions of ≈25%. Individually, blood pressure control (57.9%) had the lowest overall attainment, whereas nonsmoking status had the highest (89%). Over a median 3.0 years of follow-up, a higher baseline secondary prevention score was associated with improved outcomes in a step-wise graded relationship (adjusted hazard ratio, 0.60; 95% confidence interval, 0.47-0.77 for those patients achieving all 5 measures versus those achieving ≤2). In an international trial population, significant opportunities exist to improve the quality of cardiovascular secondary prevention care among patients with diabetes mellitus and cardiovascular disease, which in turn could lead to reduced risk of downstream cardiovascular events.

    Until recently there was little evidence that statin therapy reduced the risk of stroke recurrence. The SPARCL trial, published in 2006, was the first trial to show the benefits of statin therapy in preventing recurrent stroke. The SPARCL trial showed that treatment with atorvastatin 80mg/day reduced recurrent stroke in patients with a recent stroke or transient ischemic attack (TIA). Several post hoc analyses of different subgroups followed the SPARCL trial. They have not revealed any significant differences when patients were grouped by age, sex or type of stroke. The SPARCL trial has also helped to identify patients who may have a greater benefit from statins: Patients with carotid stenosis, with more intense lipid lowering, and those who achieve optimal levels of LDL-C, HDL-C, triglycerides, and blood pressure. The trial has also helped to identify individuals at high risk of new vascular events. Clearly there is a before and after in stroke prevention since the SPARCL trial was published.

    Full Text Available Congenital cataracts constitute an important part of blindness in childhood. It’s a curable disease which is one of the most common causes of blindness in childhood. Main treatment is surgical operation. Timing of surgery, appropriate and rapid post sur- gery visual rehabilitation have a major effect on prognosis. Surgery should be perfor-med as soon as possible after the diagnosis in order to prevent amblyopia.Visual rehabi- litation of congenital cataract includes optical correction and amblyopia treatment. The most effective treatment of amblyopia is occlusion therapy. In this article congenital cataracts were evaluated in the light of recent literature and the importance of the timing of surgery and visual rehabilitation were attempted to be emphasized.

    The impact of an acute coronary syndrome (ACS) event, such as an acute myocardial infarction (MI), is not limited to the acute management phase; patients face an elevated risk of residual atherothrombotic events that commonly requires chronic management for months or even years. Significant advances have been made in both the acute and chronic management of patients with acute MI over the past decade, resulting in improved prognoses. One of the hallmarks of modern treatment strategies is more aggressive antiplatelet treatment regimens. However, the risks of further ACS events, stroke and premature death remain elevated in these patients, and addressing this residual risk is challenging owing to interpatient variability, differences in management strategies between centres and countries, incomplete understanding of the specific pathophysiology of post-ACS thrombosis and limitations of current therapeutic approaches. The recent approval in Europe of the direct oral anticoagulant rivaroxaban for use in this setting in combination with clopidogrel and acetylsalicylic acid offers another strategy to consider in the management of these patients, and clinical strategies in this area continue to evolve. In this review, we chart the progress made over the past decade in reducing the burden of secondary thromboembolic events after acute MI and discuss the current position of and future perspectives on the inclusion of oral anticoagulants into care pathways in this setting. © 2014 The Authors.

    We sought to evaluate the success rates in achieving preventive therapeutic goals in patients who experienced an ischemic stroke (IS) and compare them with those achieved in patients with coronary artery disease (CAD). This was an observational multicenter case-control study (3 patients with IS and one control subject with CAD) performed in 1444 primary health centers in Spain. Preventive therapeutic objectives according to American Heart Association guidelines were predefined. Demographic data, vascular risk factors, and success/failure in achievement of objectives were recorded and compared between patients with IS and CAD. A total of 5458 patients were included, 4098 (75.1%) had IS and 1360 (24.9%) had CAD. Although more than 90% of patients with hypertension, diabetes, or dyslipidemia were under specific drug regimens, only about 25% achieved the recommended therapeutic objective for each risk factor. Success rate was especially low among patients with IS compared with CAD: hypertension (23.8% v 27.2%; P = .028); dyslipidemia (13.6% v 20.3%; P risk factors under control, compared with 5.6% of those with CAD (P = .006). For all patients, multivariate logistic regression model showed that independent predictors of full risk factor control were: presence of CAD as compared with IS (odds ratio [OR] 2.11; 95% confidence interval [CI] 1.35-3.29; P = .001), older age (OR 1.02; 95% CI 1.00-1.04; P = .028), and having less than 3 risk factors (OR 16.98; 95% CI 9.02-31.97; P risk factor control.

    Lipids have important functions in the human body, but high serum cholesterol level is an important risk factor for cardiovascular and cerebrovascular diseases. Prevention of stroke includes modifying risk factors, like dyslipidemias. Based on this theory, we examined in practice the possible role of a public care neurology and stroke department with a large patient turnover in vascular risk screening with regard to the diagnosis of hyperlipidemia. We reviewed all the medical records (irrespective of disease group;) of patients hospitalized in 2007 at Department of Neurclogy and Stroke Center of Szent János Hospital of the Municipality of the City of Budapest. Patients included in the study were classified into three groups: (1) those admitted with acute stroke; (2) those with a history of acute stroke, but without evidence of a novel cerebrovascular event; (3) no history and evidence of cerebrovascular disease during hospitalization. Our data show that 17.6% of patients was diagnosed with hyperlipidemia during hospital care, and another 18.5% was known to have elevated cholesterol levels. Altogether, 36.1% of the 1438 patients evaluated had hyper ipidemia. Known hypercholesterolemia was 18.4% in patierts admitted for acute stroke, 26.9% in patients formerly (but not currently) treated for cerebrovascular disease, and 13.6% in the third group. Newly diagnosed elevated cholesterol levels had highest rate (22.6%) in former stroke patierts (currently treated for other diseases); 20.4% in patients with acute stroke, and 13.2% in the third group. In the first two groups, the number of patients newly diagnosed with elevated serum cholesterol almost equaled to those with already known hypercholesterolemia. Based on our data, neurology departments have an important role in diagnosing hyperlipidemia and vascular prevention.

    To assess the emergency response planning and prevention strategies for sudden cardiac arrest (SCA) across a wide range of professional football clubs in England. A written survey was sent to all professional clubs in the English football league, namely the Premiership, Championship, League 1 and League 2. Outcomes included: (1) number of clubs performing cardiac screening and frequency of screening; (2) emergency planning and documentation; (3) automated external defibrillator (AED) training and availability; and (4) provision of emergency services at sporting venues. 79 clubs (86%) responded to the survey. 100% clubs participated in cardiac screening. All clubs had AEDs available on match days and during training sessions. 100% Premiership clubs provided AED training to designated staff. In contrast, 30% of lower division clubs with AEDs available did not provide formal training. Most clubs (n=66; 83%) reported the existence of an emergency action plan for SCA but formal documentation was variable. All clubs in the Premiership and League 1 provided an ambulance equipped for medical emergencies on match days compared with 75% of clubs in the Championship and 66% in League 2. The majority of football clubs in England have satisfactory prevention strategies and emergency response planning in line with European recommendations. Additional improvements such as increasing awareness of European guidelines for emergency planning, AED training and mentorship with financial support to lower division clubs are necessary to further enhance cardiovascular safety of athletes and spectators and close the gap between the highest and lower divisions. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

They stress the need to take into account polymorbidity and polypharmacy that increase the risk of adverse reactions due to the use of both statins and their drug-drug interactions, which requires an assessment of risk/benefit ratio. In addition, there is a need for development of reliable prognostic tools to predict relevant outcomes (e.g., stroke, decrease in functionality/independence, quality of life reduction and rationales for lipid-lowering therapy in the elderly and also their adherence to treatment.

    INTRODUZIONE: gli incidenti stradali sono l'ottava causa di morte al mondo e la prima tra i giovani di 15-29 anni. In Italia il Piano nazionale sicurezza stradale raccomanda l'educazione scolastica per la prevenzione degli incidenti stradali; ad oggi non esistono documenti che raccolgano evidenze di efficacia sugli interventi educativi stradali e le rapportino al contesto italiano. OBIETTIVI: riassumere e discutere ciò che è noto in letteratura riguardo agli interventi scolastici per la prevenzione degli incidenti stradali. METODI: sono state ricercate linee guida e revisioni sistematiche usando i seguenti criteri di inclusione: popolazione di età inferiore ai 25 anni di entrambi i sessi; interventi scolastici di educazione stradale; effetti su indicatori primari di esito come riduzione degli incidenti stradali, astinenza dalla guida sotto l'effetto di alcol e dall'accettare passaggi in macchina da guidatori che sono sotto l'effetto di alcol; effetti su indicatori secondari di esito come conoscenze e competenze sui comportamenti di guida sicura. RISULTATI: sono state identificate due revisioni sistematiche. L'educazione stradale nelle scuole non mostra evidenza di efficacia (rischio relativo 1,03; IC95% 0,98-1,08) nel ridurre gli incidenti. Programmi scolastici più specifici mostrano risultati solo in parte convincenti per l'adozione di comportamenti sicuri come l'astinenza dal guidare sotto l'effetto di alcol e dall'accettare passaggi in macchina da guidatori che sono sotto l'effetto di alcol. DISCUSSIONE: le revisioni incluse non hanno trovato programmi efficaci nella riduzione degli incidenti stradali o dei fattori che possano determinarli. Nell'attesa di studi più recenti, appare opportuno promuovere l'implementazione di interventi misti, scolastici e di comunità, che hanno mostrato maggiori prove di efficacia.

    In mind-body medicine (MBM), conventional lifestyle modification measures such as dietary counseling and exercise are supplemented with relaxation techniques and psychological motivational elements. This review studied the effect of MBM on cardiac events and mortality in patients with coronary heart disease (CHD). This review is based on publications up to and including January 2015 that were retrieved by a systematic search in PubMed, the Cochrane Library, and Scopus. Randomized controlled trials of the effect of MBM programs (versus standard treatment) on cardiac events, overall mortality, and/or cardiac mortality were analyzed. Atherosclerosis, blood pressure, LDL cholesterol, and the body mass index (BMI) were chosen as secondary outcomes. Random-effects meta-analyses were performed. The risk of bias was assessed with the Cochrane tool. Twelve trials, performed on a total of 1085 patients, were included in the analysis. Significant differences between groups were found with respect to cardiac events (odds ratio [OR]: 0.38; 95% confidence interval [CI]: 0.23-0.61; p<0.01; heterogeneity [I2]: 0%), but not overall mortality (OR: 0.82; 95% CI: 0.46-1.45; p = 0.49; I2: 0%) or cardiac mortality (OR: 0.98; 95% CI: 0.43-2.25; p = 0.97; I2: 0%). Significant differences between groups were also found with respect to atherosclerosis (mean difference [MD] = -7.86% diameter stenosis; 95% CI: -15.06-[-0.65]; p = 0.03; I2: 0%) and systolic blood pressure (MD = -3.33 mm Hg; 95% CI: -5.76-[-0.91]; p<0.01; I2: 0%), but not with respect to diastolic blood pressure, LDL cholesterol, or BMI. In patients with CHD, MBM programs can lessen the occurrence of cardiac events, reduce atherosclerosis, and lower systolic blood pressure, but they do not reduce mortality. They can be used as a complement to conventional rehabilitation programs.

    Purpose: Aim of this retrospective study was to evaluate cataract incidence in a homogeneous group of patients after total-body irradiation followed by autologous bone marrow transplantation or peripheral blood stem cell transplantation. Method and Materials: Between 11/1982 and 6/1994 in total 260 patients received in our hospital total-body irradiation for treatment of haematological malignancy. In 1996-96 patients out of these 260 patients were still alive. 85 from these still living patients (52 men, 33 women) answered evaluable on a questionnaire and could be examined ophthalmologically. Median age of these patients was 38,5 years (15 - 59 years) at time of total-body irradiation. Radiotherapy was applied as hyperfractionated total-body irradiation with a median dose of 14,4 Gy in 12 fractions over 4 days. Minimum time between fractions was 4 hours, photons with a energy of 23 MeV were used, and the dose rate was 7 - 18 cGy/min. Results: Median follow-up is now 5,8 years (1,7 - 13 years). Cataract occurred in (28(85)) patients after a median time of 47 months (1 - 104 months). In 6 out of these 28 patients who developed a cataract, surgery of the cataract was performed. Whole-brain irradiation prior to total-body irradiation was more often in the group of patients developing a cataract (14,3%) vs. 10,7% in the group of patients without cataract. Conclusion: Cataract is a common side effect of total-body irradiation. Cataract incidence found in our patients is comparable to results of other centres using a fractionated regimen for total-body irradiation. The hyperfractionated regimen used in our hospital does obviously not result in a even lower cataract incidence. In contrast to acute and late toxicity in other organ/organsystems, hyperfractionation of total-body irradiation does not further reduce toxicity for the eye-lens. Dose rate may have more influence on cataract incidence

  7. Contemporary Reflections on the Safety of Long-Term Aspirin Treatment for the Secondary Prevention of Cardiovascular Disease

    Aspirin has been the cornerstone of therapy for the secondary prevention treatment of patients with cardiovascular disease since landmark trials were completed in the late 1970s and early 1980s that demonstrated the efficacy of aspirin for reducing the risk of ischemic events. Notwithstanding the consistent benefits demonstrated with apirin for both acute and chronic cardiovascular disease, there are a number of toxicities associated with aspirin that have been showcased by recent long-term clinical trials that have included an aspirin monotherapy arm. As an inhibitor of cyclooxygenase, aspirin impairs gastric mucosal protective mechanisms. Prior trials have shown that up to 15–20% of patients developed gastrointestinal symptoms with aspirin monotherapy and roughly 1% of patients per year had a clinically significant bleeding event, including 1 in 1000 patients who suffered an intracranial or fatal bleed. These risks have been shown to be compounded for patients with acute coronary syndromes (ACS) and those undergoing percutaneous coronary intervention (PCI), who are also treated with other anti-thrombotic agents during the acute care/procedural period, as well as for an extended time period afterwards. Given observations of substantial increases in bleeding rates from many prior long-term clinical trials that have evaluated aspirin together with other oral platelet inhibitors or oral anti-coagulants, the focus of contemporary research has pivoted towards tailored anti-thrombotic regimens that attempt to either shorten the duration of exposure to aspirin or replace aspirin with an alternative anti-thrombotic agent. While these shifts are occurring, the safety profile of aspirin when used for the secondary prevention treatment of patients with established cardiovascular disease deserves further consideration.

    Research consistently indicates that young mothers are at elevated risk for adverse social and economic risks. Recent attention has been paid to the value of maternal educational attainment for their children's economic and social outcomes. Pursuit of post-secondary education requires mothers to balance multiple roles, potentially stressing the parent-child relationship. Yet, almost no studies have addressed parenting and associated stress in young mothers enrolled in post-secondary education, and no preventive intervention trials have been conducted. We screened young mothers (parenting stress, and participated in a randomized controlled trial to assess the efficacy of a web-based parenting intervention (Triple P Online) in reducing parenting stress and dysfunctional discipline (N = 52). Mothers were randomly assigned to the web-based parenting program condition or to a waitlist control condition. Mothers who completed at least the first four core modules of the online program had lower scores on the Parenting Scale's subscales (Overreactivity, Verbosity, and Laxness), compared to those who did not complete four or more modules. No intervention effects were obtained for parenting stress. The current study provides preliminary evidence of the efficacy of this online parenting program for reducing risk for dysfunctional discipline in student mothers. Future research is warranted to replicate these findings, and to test whether provision of supplemental support for implementation, or briefer program formats may promote both program compliance and outcomes related to reducing parenting stress.

    To publish the outcomes and complications of age-related cataract surgery in Cadiz (Spain). Due to the lack of national audits, a comparison was made between the results obtained here and those of the most recent European audit, EUREQUO (2013), and the British audit RCOphth NOD (2015). A prospective, longitudinal, before-after study of 312 patients undergoing cataract surgery in the University Hospitals of Puerta del Mar and Puerto Real (Cadiz), in 2013-14. Outcome measurements included sociodemographic characteristics, visual acuity (VA), symptoms secondary to cataract, ocular comorbidity, waiting time, expertise of surgeon (consultant vs. trainee), rate and type of surgical complications. The median age at surgery was 73.92±7.31. Almost all (98.3%) of patients at consultation had a VA ≥0.60logMAR, with a mean pre-surgical VA of 1.01logMAR (0.92-1.10). There was a 6.7% complication rate, with 3.8% posterior capsule ruptures and 2.8% corneal decompensations. No cases of endophthalmitis occurred. The mean post-operative VA was 0.28logMAR (0.22-0.33). More than three-quarters (78.8%) of cases achieved a post-operative VA ≤0.3logMAR, and 27.6% of cases achieved a VA ≤0.0logMAR. Our success rate was inferior to the EUREQUO and RCOphth NOD studies, with the percentage of patients acquiring a postoperative VA ≤0.3logMAR being 98% and 89%, respectively. However, the populations were not comparable. It is hoped that this study will encourage other public hospitals in Spain to undertake audits and share their results, in order to provide a tool for constructive criticism and quality improvement initiatives.

    Full Text Available Background: Healthy lifestyles incorporated in early ages could influence the most important behaviours and risk factors for atherosclerotic vascular disease in order to reduce the incidence of this condition during adulthood. Objective: To assess the effectiveness of the educational-participatory intervention on students' knowledge as to cardiovascular risk factors. Material: An educational intervention with a quasi-experimental design was conducted from April 2007 to October 2008 in eighth grade junior high school students from Old Havana (the intervention group and Center Havana (the control group. The nonparametric Chi square tests from McNemar and Mantel-Haenszel were used. Results: There were significant statistical associations with a confidence limit of 95% between initial and final state of knowledge in relation to cardiovascular risk factors in the intervention group (p = 0.0001, in the control group (p = 0.035 and between the study group versus the control group after the intervention (p = 0.0001. Conclusions: An educational-participatory program for health promotion and prevention of major risk factors of cardiovascular disease (inadequate dietary habits, smoking and physical inactivity among adolescents, contributes to increase their knowledge and encourages the adoption of healthy daily habits and lifestyles.

    Sudden death and catastrophic injuries during sport can be attenuated with the implementation of evidence-based health and safety policies. However, the extent of the implementation of these policies within secondary school athletics is unknown. To provide an assessment of the implementation of health and safety policies pertaining to the leading causes of sudden death and catastrophic injuries in sport within secondary school athletics in the United States. Descriptive epidemiology study. A rubric for evidence-based practices for preventing the leading causes of death and catastrophic injuries in sport was created. The rubric comprised 5 equally weighted sections for sudden cardiac arrest, head injuries, exertional heat stroke, appropriate medical coverage, and emergency preparedness. State high school athletic association (SHSAA) policies, enacted legislation, and Department of Education policies were extensively reviewed for all 50 states and the District of Columbia. States meeting the specific criteria in the rubric, which required policies to be mandated for all SHSAA member schools, were awarded credit; the weighted scores were tabulated to calculate an aggregate score. States were then ranked from 1 (best) to 51 (worst) based on the aggregate score achieved. The median score on the rubric was 47.1% (range, 23.00%-78.75%). States ranked 1 through 10 (from 78.75% to 56.98%) were North Carolina, Kentucky, Massachusetts, New Jersey, South Dakota, Missouri, Washington, Hawaii, Wisconsin, and Georgia, respectively. States ranked 11 through 20 (from 56.03% to 50.55%) were Arkansas, New York, Mississippi, West Virginia, Oregon, Illinois, Tennessee, Arizona, Texas, and District of Columbia, respectively. States ranked 21 through 30 (from 49.40% to 44.00%) were Virginia, Pennsylvania, Florida, New Mexico, Alabama, Maine, Rhode Island, Indiana, Nevada, and Utah, respectively. States ranked 31 through 40 (from 43.93% to 39.80%) were Ohio, Delaware, Alaska, Vermont

    Climate change is predicted to be one of the largest global health threats of the 21st century. Health care itself is a large contributor to carbon emissions. Determining the carbon footprint of specific health care activities such as cataract surgery allows the assessment of associated emissions and identifies opportunities for reduction. To assess the carbon footprint of a cataract pathway in a British teaching hospital. This was a component analysis study for one patient having first eye cataract surgery in the University Hospital of Wales, Cardiff. Activity data was collected from three sectors, building and energy use, travel and procurement. Published emissions factors were applied to this data to provide figures in carbon dioxide equivalents (CO2eq). The carbon footprint for one cataract operation was 181.8 kg CO2eq. On the basis that 2230 patients were treated for cataracts during 2011 in Cardiff, this has an associated carbon footprint of 405.4 tonnes CO2eq. Building and energy use was estimated to account for 36.1% of overall emissions, travel 10.1% and procurement 53.8%, with medical equipment accounting for the most emissions at 32.6%. This is the first published carbon footprint of cataract surgery and acts as a benchmark for other studies as well as identifying areas for emissions reduction. Within the procurement sector, dialogue with industry is important to reduce the overall carbon footprint. Sustainability should be considered when cataract pathways are designed as there is potential for reduction in all sectors with the possible side effects of saving costs and improving patient care.

    Highlights: •We investigate free calcium as a central signalling element in endothelial cells. •Inhibition of glycolysis with 2-deoxy-D-glucose reduces cellular ATP. •This manoeuvre leads to a biphasic increase and overload of free calcium. •Pre-treatment with lithium for 24 h abolishes both phases of the calcium increase. •This provides a new strategy to protect endothelial calcium homeostasis and barrier function. -- Abstract: Cytosolic free calcium concentration ([Ca{sup 2+}]{sub i}) is a central signalling element for the maintenance of endothelial barrier function. Under physiological conditions, it is controlled within narrow limits. Metabolic inhibition during ischemia/reperfusion, however, induces [Ca{sup 2+}]{sub i} overload, which results in barrier failure. In a model of cultured porcine aortic endothelial monolayers (EC), we addressed the question of whether [Ca{sup 2+}]{sub i} overload can be prevented by lithium treatment. [Ca{sup 2+}]{sub i} and ATP were analysed using Fura-2 and HPLC, respectively. The combined inhibition of glycolytic and mitochondrial ATP synthesis by 2-desoxy-D-glucose (5 mM; 2-DG) plus sodium cyanide (5 mM; NaCN) caused a significant decrease in cellular ATP content (14 ± 1 nmol/mg protein vs. 18 ± 1 nmol/mg protein in the control, n = 6 culture dishes, P < 0.05), an increase in [Ca{sup 2+}]{sub i} (278 ± 24 nM vs. 71 ± 2 nM in the control, n = 60 cells, P < 0.05), and the formation of gaps between adjacent EC. These observations indicate that there is impaired barrier function at an early state of metabolic inhibition. Glycolytic inhibition alone by 10 mM 2-DG led to a similar decrease in ATP content (14 ± 2 nmol/mg vs. 18 ± 1 nmol/mg in the control, P < 0.05) with a delay of 5 min. The [Ca{sup 2+}]{sub i} response of EC was biphasic with a peak after 1 min (183 ± 6 nM vs. 71 ± 1 nM, n = 60 cells, P < 0.05) followed by a sustained increase in [Ca{sup 2+}]{sub i}.

    Comprehensive cardiac rehabilitation (CCR), which integrates structured lifestyle interventions and medications, reduces morbidity and mortality among cardiac patients. CCR has not typically been used with cerebrovascular populations, despite important commonalities with heart patients. We tested feasibility and effectiveness of 6-month outpatient CCR for secondary prevention after transient ischemic attack or mild, nondisabling stroke. This article presents risk factors. A future article will discuss psychological outcomes. Consecutive consenting subjects having sustained a transient ischemic attack or mild, nondisabling stroke within the previous 12 months (mean, 11.5 weeks; event-to-CCR entry) with ≥1 vascular risk factor, were recruited from a stroke prevention clinic providing usual care. We measured 6-month CCR outcomes following a prospective cohort design. Of 110 subjects recruited from January 2005 to April 2006, 100 subjects (mean age, 64.9 years; 46 women) entered and 80 subjects completed CCR. We obtained favorable, significant intake-to-exit changes in: aerobic capacity (+31.4%; Pstroke, offering a promising model for vascular protection across chronic disease entities. We know of no similar previous investigation, and are now conducting a randomized trial.

    To evaluate the safety and efficacy of percutaneous device closure of patent foramen ovale (PFO) for secondary prevention of ischemic stroke BACKGROUND: Stroke remains the leading cause of serious long-term disability in the United States. The effectiveness of a percutaneous PFO closure in the prevention of recurrent cryptogenic strokes has not been established. We performed a literature search using PubMed, EMBASE, Cochrane Central Register of Controlled Trials, Google Scholar, and Internet-based sources from January 2003 to September 2017. Randomized controlled trails (RCTs) comparing percutaneous PFO closure to medical therapy alone. Five RCTs (CLOSURE I, PC Trial, REDUCE, RESPECT, and CLOSE) with 1,829 patients in the device group and 1,611 patients in the medical group met inclusion criteria. The cumulative incidence of recurrent stroke was 2.02% in the PFO closure arm and 4.4% in the medical therapy group (RR 0.42, 95%CI 0.20, 0.91; P = 0.03). There was no difference in the incidence of death [0.7% vs. 0.9%; RR 0.76 (95% CI 0.35, 1.64), P = 0.49] or adverse events during the follow-up period [24.6% vs. 23.7% (RR 1.03; 95% CI 0.91, 1.16), P = 0.65] between the closure and medical therapy groups. Incidence of atrial fibrillation was significantly higher in closure group compared to medical therapy [4% vs. 0.6% (RR 4.73; 95% CI 2.09, 10.70), P = 0.0002]. The comparative effectiveness of PFO closure (compared to medical therapy) was significantly more pronounced in those younger than 45 years, males, larger shunts and disc design platforms (P < 0.05). Based on the results of this analysis of randomized trial data, percutaneous PFO closure appears to be a safe and effective therapeutic option for the secondary prevention of ischemic stroke in patients with PFO and cryptogenic stroke. © 2018 Wiley Periodicals, Inc.

    Smoking prevalence rates among Dutch children increase rapidly after they transit to secondary school, in particular among children with a low socioeconomic status (SES). Web-based, computer-tailored programs supplemented with prompt messages may be able to empower children to prevent them from starting to smoke when they transit to secondary school. The main aim of this study is to evaluate whether computer-tailored feedback messages, with and without prompt messages, are effective in decreasing children's smoking intentions and smoking behavior after 12 and 25 months of follow-up. Data were gathered at baseline (T0), and after 12 months (T1) and 25 months (T2) of follow-up of a smoking prevention intervention program called Fun without Smokes. A total of 162 schools were randomly allocated to a no-intervention control group, an intervention prompt group, or an intervention no-prompt group. A total of 3213 children aged 10 to 12 years old participated in the study and completed a Web-based questionnaire assessing their smoking intention, smoking behavior, and sociocognitive factors, such as attitude, social influence, and self-efficacy, related to smoking. After completion, children in the intervention groups received computer-tailored feedback messages in their own email inbox and those messages could be accessed on the intervention website. Children in the prompt group received prompt messages, via email and short message service (SMS) text messaging, to stimulate them to reuse the intervention website with nonsmoking content. Multilevel logistic regression analyses were performed using multiple imputations to assess the program effects on smoking intention and smoking behavior at T1 and T2. A total of 3213 children participated in the Fun without Smokes study at T0. Between T0 and T1 a total of 1067 children out of the original 3213 (33.21%) dropped out of the study. Between T0 and T2 the number of children that did not participate in the final measurement was

    The number of people coming for cataract surgery in Madagascar remains low and most ophthalmologists could do many more surgeries than currently done. Knowing why people identified with cataract do not accept surgery will help to design programs that use existing resources more effectively. The study was carried out in Sava Region of Madagascar. People with blinding (acceptance were proximity to hospital (people from Sambava district were twice as likely to present as people from more distant districts) and perceived price of transport and food (being higher for people not accepting). The actual price of surgery was not the main barrier to acceptance of surgery; instead it appears that distance to the hospital and the willingness to pay are important predictors. Strategies to improve uptake need to be revised in order to ensure that people have access to and use cataract surgical services.

    reported) to whole grain versus lower whole grain or refined grain control groups. We found no studies that reported the effect of whole grain diets on total cardiovascular mortality or cardiovascular events (total myocardial infarction, unstable angina, coronary artery bypass graft surgery, percutaneous transluminal coronary angioplasty, total stroke). All included studies reported the effect of whole grain diets on risk factors for cardiovascular disease including blood lipids and blood pressure. All studies were in primary prevention populations and had an unclear or high risk of bias, and no studies had an intervention duration greater than 16 weeks.Overall, we found no difference between whole grain and control groups for total cholesterol (mean difference 0.07, 95% confidence interval -0.07 to 0.21; 6 studies (7 comparisons); 722 participants; low-quality evidence).Using GRADE, we assessed the overall quality of the available evidence on cholesterol as low. Four studies were funded by independent national and government funding bodies, while the remaining studies reported funding or partial funding by organisations with commercial interests in cereals. There is insufficient evidence from RCTs of an effect of whole grain diets on cardiovascular outcomes or on major CVD risk factors such as blood lipids and blood pressure. Trials were at unclear or high risk of bias with small sample sizes and relatively short-term interventions, and the overall quality of the evidence was low. There is a need for well-designed, adequately powered RCTs with longer durations assessing cardiovascular events as well as cardiovascular risk factors.

    To determine the relationship between cataract severity and socioeconomic status (SES). Retrospective, observational case series. A total of 1350 eyes underwent phacoemulsification cataract extraction by a single surgeon using an Alcon Infiniti system. Cataract severity was measured using phaco time in seconds. SES was measured using area-level aggregate census data: median income, education, proportion of common-law couples, and employment rate. Preoperative best corrected visual acuity was obtained and converted to logarithm of the minimum angle of resolution values. For patients undergoing bilateral surgery, the generalized estimating equation was used to account for the correlation between eyes. Univariate analyses were performed using simple regression, and multivariate analyses were performed to account for variables with significant relationships (p < 0.05) on univariate testing. Sensitivity analyses were performed to assess the effect of including patient age in the controlled analyses. Multivariate analyses demonstrated that cataracts were more severe when the median income was lower (p = 0.001) and the proportion of common-law couples living in a patient's community (p = 0.012) and the unemployment rate (p = 0.002) were higher. These associations persisted even when controlling for patient age. Patients of lower SES have more severe cataracts. Copyright © 2013 Canadian Ophthalmological Society. Published by Elsevier Inc.

    Full Text Available Background and Purpose: Patients who experience a stroke or transient ischemic attack (TIA are known to be at high risk of subsequent vascular events, underscoring the need for secondary preventive intervention. However, previous studies have indicated insufficiency in the implementation of secondary prevention, emphasizing the need to develop effective methods of follow-up. In the present study, we examined the potential of implementing a telephone-based, nurse-led, secondary preventive follow-up in stroke and TIA patients on a population level by analyzing the participation rate, reasons for nonparticipation, and one-year mortality. Methods: Between January 1, 2010 and December 31, 2011, all patients admitted to Östersund hospital, Sweden, and diagnosed with either stroke or TIA were considered for inclusion into the secondary preventive follow-up. Baseline data were collected at the hospital, and reasons for nonparticipation were documented. Multivariate logistic regression was performed to identify predictors of the patient decision not to participate and to explore independent associations between baseline characteristics and exclusion. A one-year follow-up of mortality was also performed; the survival functions of the three groups (included, excluded, declining participation was calculated using the Kaplan-Meier estimator. Results: From a total of 810 identified patients, 430 (53.1% were included in the secondary preventive follow-up, 289 (35.7% were excluded mainly due to physical or cognitive disability, and 91 (11.2% declined participation. Age ≥85 years, ischemic and hemorrhagic stroke, modified Rankin scale score >3, body mass index ≥25, congestive heart failure, and lower education level were independently associated with exclusion, whereas lower education level was the only factor independently associated with the patient decision not to participate. Exclusion was associated with a more than 12 times higher risk of mortality

    OBJECTIVES To compare the incidence of adverse events, visual outcomes and economic costs of sequential versus simultaneous bilateral cataract surgery for infants with congenital cataracts. METHODS We retrospectively reviewed the incidence of adverse events, visual outcomes and medical payments associated with simultaneous versus sequential bilateral cataract surgery for infants with congenital cataracts who underwent cataract surgery when 6 months of age or younger at our institution. RESULTS Records were available for 10 children who underwent sequential surgery at a mean age of 49 days for the first eye and 17 children who underwent simultaneous surgery at a mean age of 68 days (p=.25). We found a similar incidence of adverse events between the two treatment groups. Intraoperative or postoperative complications occurred in 14 eyes. The most common postoperative complication was glaucoma. No eyes developed endophthalmitis. The mean absolute interocular difference in logMAR visual acuities between the two treatment groups was 0.47±0.76 for the sequential group and 0.44±0.40 for the simultaneous group (p=.92). Hospital, drugs, supplies and professional payments were on average 21.9% lower per patient in the simultaneous group. CONCLUSIONS Simultaneous bilateral cataract surgery for infants with congenital cataracts was associated with a 21.9% reduction in medical payments and no discernible difference in the incidence of adverse events or visual outcome.

    Full Text Available AIM: To investigate the genetic mutations that are associated the hereditary autosomal dominant cataract in a Chinese family. METHODS: A Chinese family consisting of 20 cataract patients (including 9 male and 11 female and 2 unaffected individuals from 5 generations were diagnosed to be a typical autosomal dominant cataract pedigree. Genomic DNA samples were extracted from the peripheral blood cells of the participants in this pedigree. Exon sequence was used for genetic mutation screening. In silico analysis was used to study the structure characteristics of connexin 46 (CX46 mutant. Immunoblotting was conduceted for testing the expression of CX46. RESULTS: To determine the involved genetic mutations, 11 well-known cataract-associated genes (cryaa, cryab, crybb1, crybb2, crygc, crygd, Gja3, Gja8, Hsf4, Mip and Pitx3 were chosen for genetic mutation test by using exon sequencing. A novel cytosine insertion at position 1195 of CX46 cDNA (c.1194_1195ins C was found in the samples of 5 tested cataract patients but not in the unaffected 2 individuals nor in normal controls, which resulted in 30 amino acids more extension in CX46C-terminus (cx46fs400 compared with the wild-type CX46. In silico protein structure analysis indicated that the mutant showed distinctive hydrophobicity and protein secondary structure compared with the wild-type CX46. The immunoblot results revealed that CX46 protein, which expressed in the aging cataract lens tissues, was absence in the proband lens. In contrast, CX50, alpha A-crystallin and alphaB-crystallin expressed equally in both proband and aging cataract tissues. Those results revealed that the cx46fs400 mutation could impair CX46 protein expression. CONCLUSION: The insertion of cytosine at position 1195 of CX46 cDNA is a novel mutation site that is associated with the autosomal dominant cataracts in this Chinese family. The C-terminal frameshift mutation is involved in regulating CX46 protein expression.

    More than 8.5 million Germans suffer from chronic diseases attributable to smoking. Education Against Tobacco (EAT) is a multinational network of medical students who volunteer for school-based prevention in the classroom setting, amongst other activities. EAT has been implemented in 28 medical schools in Germany and is present in 13 additional countries around the globe. A recent quasi-experimental study showed significant short-term smoking cessation effects on 11-to-15-year-old adolescents. The aim of this study was to provide the first randomized long-term evaluation of the optimized 2014 EAT curriculum involving a photoaging software for its effectiveness in reducing the smoking prevalence among 11-to-15-year-old pupils in German secondary schools. A randomized controlled trial was undertaken with 1504 adolescents from 9 German secondary schools, aged 11-15 years in grades 6-8, of which 718 (47.74%) were identifiable for the prospective sample at the 12-month follow-up. The experimental study design included measurements at baseline (t1), 6 months (t2), and 12 months postintervention (t3), via questionnaire. The study groups consisted of 40 randomized classes that received the standardized EAT intervention (two medical student-led interactive modules taking 120 minutes total) and 34 control classes within the same schools (no intervention). The primary endpoint was the difference in smoking prevalence from t1 to t3 in the control group versus the difference from t1 to t3 in the intervention group. The differences in smoking behavior (smoking onset, quitting) between the two groups, as well as gender-specific effects, were studied as secondary outcomes. None of the effects were significant due to a high loss-to-follow-up effect (52.26%, 786/1504). From baseline to the two follow-up time points, the prevalence of smoking increased from 3.1% to 5.2% to 7.2% in the control group and from 3.0% to 5.4% to 5.8% in the intervention group (number needed to treat [NNT

  8. Acid phosphatase and lipid peroxidation in human cataractous lens epithelium

    Full Text Available The anterior lens epithelial cells undergo a variety of degenerative and proliferative changes during cataract formation. Acid phosphatase is primarily responsible for tissue regeneration and tissue repair. The lipid hydroperoxides that are obtained by lipid peroxidation of polysaturated or unsaturated fatty acids bring about deterioration of biological membranes at cellular and tissue levels. Acid phosphatase and lipid peroxidation activities were studied on the lens epithelial cells of nuclear cataract, posterior subcapsular cataract, mature cataract, and mixed cataract. Of these, mature cataractous lens epithelium showed maximum activity for acid phosphatase (516.83 moles of p-nitrophenol released/g lens epithelium and maximum levels of lipid peroxidation (86.29 O.D./min/g lens epithelium. In contrast, mixed cataractous lens epithelium showed minimum activity of acid phosphatase (222.61 moles of p-nitrophenol released/g lens epithelium and minimum levels of lipid peroxidation (54.23 O.D./min/g lens epithelium. From our study, we correlated the maximum activity of acid phosphatase in mature cataractous lens epithelium with the increased areas of superimposed cells associated with the formation of mature cataract. Likewise, the maximum levels of lipid peroxidation in mature cataractous lens epithelium was correlated with increased permeability of the plasma membrane. Conversely, the minimum levels of lipid peroxidation in mixed cataractous lens epithelium makes us presume that factors other than lipid peroxidation may also account for the formation of mixed type of cataract.

    Stroke is the prime cause of morbidity and mortality in the general population, and hypertension will increase the recurrence and mortality of stroke. We report a protocol of a pragmatic randomized controlled trial (RCT) using blood pressure (BP)-lowering acupuncture add-on treatment to treat patients with hypertension and stroke. This is a large-scale, multicenter, subject-, assessor- and analyst-blinded, pragmatic RCT. A total of 480 patients with hypertension and ischemic stroke will be randomly assigned to two groups: an experimental group and a control group. The experimental group will receive "HuoXueSanFeng" acupuncture combined with one antihypertensive medication in addition to routine ischemic stroke treatment. The control group will only receive one antihypertensive medication and basic treatments for ischemic stroke. HuoXueSanFeng acupuncture will be given for six sessions weekly for the first 6 weeks and three times weekly for the next 6 weeks. A 9-month follow-up will, thereafter, be conducted. Antihypertensive medication will be adjusted based on BP levels. The primary outcome will be the recurrence of stroke. The secondary outcomes including 24-h ambulatory BP, the TCM syndrome score, the Short Form 36-item Health Survey (SF-36), the National Institute of Health Stroke Scale (NIHSS), as well as the Barthel Index (BI) scale will be assessed at baseline, 6 weeks and 12 weeks post initiating treatments; cardiac ultrasound, carotid artery ultrasound, transcranial Doppler, and lower extremity ultrasound will be evaluated at baseline and 12 weeks after treatment. The safety of acupuncture will also be assessed. We aim to determine the clinical effects of controlling BP for secondary prevention of stroke with acupuncture add-on treatment.

    Full Text Available Introduction This focused review examines the use and effectiveness of self-management strategies in preventing or managing pain, which is among the most common secondary conditions faced by individuals with a mobility disability. Methods This focused review was part of a two-phase comprehensive scoping review. Phase I was a comprehensive scoping review of the literature targeting multiple outcomes of self-management interventions for those with mobility impairment, and Phase II was a focused review of the literature on self-management interventions that target pain as a primary or secondary outcome. Two authors searched CINAHL, PubMed, and PsyclNFO for papers published from January 1988 through August 2014 using specified search terms. Following the scoping review, the authors independently screened and selected the studies and reviewed the eligible studies, and the first author extracted data from the included studies. Results The scoping review yielded 40 studies that addressed pain self-management interventions for those living with mobility impairment. These 40 accumulated papers revealed a heterogeneous evidence base in terms of setting (clinic, community, and online, target populations, intervention duration (3 weeks to 24 months, and mode (health-care providers and lay leaders. Most of the reviewed studies reported that the self-management intervention led to significant reduction of pain over time, suggesting that self-management may be a promising approach for addressing pain experienced by people who live with mobility limitations. Discussion This review also reveals moderate-to-high bias across studies, and findings indicate that future research should enhance the methodological quality to provide stronger evidence about the effectiveness of self-management strategies for reducing pain among those with mobility impairments.

    Amblyopia is a neurodevelopmental disorder of vision associated with decreased visual acuity, poor or absent stereopsis, and suppression of information from one eye.(1,2) Amblyopia may be caused by strabismus (strabismic amblyopia), refractive error (anisometropic amblyopia), or deprivation from obstructed vision (deprivation amblyopia). 1 In the developed world, amblyopia is the most common cause of childhood visual impairment, 3 which reduces quality of life 4 and also almost doubles the lifetime risk of legal blindness.(5, 6) Successful treatment of amblyopia greatly depends on early detection and treatment of predisposing disorders such as congenital cataract, which is the most common cause of deprivational amblyopia. Understanding the genetic causes of congenital cataract leads to more effective screening tests, early detection and treatment of infants and children who are at high risk for hereditary congenital cataract.

    Microwaves most commonly cause anterior and/or posterior subcapsular lenticular opacities in experimental animals and, as shown in epidemiologic studies and case reports, in human subjects. The formation of cataracts seems to be related directly to the power of the microwave and the duration of exposure. The mechanism of cataractogenesis includes deformation of heat-labile enzymes, such as glutathione peroxide, that ordinarily protect lens cell proteins and membrane lipids from oxidative damage. Oxidation of protein sulfhydryl groups and the formation of high-molecular-weight aggregates cause local variations in the orderly structure of the lens cells. An alternative mechanism is thermoelastic expansion through which pressure waves in the aqueous humor cause direct physical damage to the lens cells. Cataracts induced by ionizing radiation (e.g., X-rays and gamma rays) usually are observed in the posterior region of the lens, often in the form of a posterior subcapsular cataract. Increasing the dose of ionizing radiation causes increasing opacification of the lens, which appears after a decreasing latency period. Like cataract formation by microwaves, cataractogenesis induced by ionizing radiation is associated with damage to the lens cell membrane. Another possible mechanism is damage to lens cell DNA, with decreases in the production of protective enzymes and in sulfur-sulfur bond formation, and with altered protein concentrations. Until further definitive conclusions about the mechanisms of microwaves and ionizing radiation induced cataracts are reached, and alternative protective measures are found, one can only recommend mechanical shielding from these radiations to minimize the possibility of development of radiation-induced cataracts. 74 references

    Full Text Available The case history of a sixty-two-year-old lady, who presented with a bleb in the upper part of her left eye following cataract surgery was studied. The patient had no prior history of any glaucoma surgery. Gonioscopy revealed fishmouthing of the internal aspect of the scleral tunnel incision. The diagnosis of post-cataract filtering bleb was made which was managed by resuturing the wound. This case highlights the use of gonioscopy to visualise and evaluate the internal wound and discusses intraoperative recognition of internal leak and its management with horizontal sutures.

    Conclusion: CSR has increased in Yemen in the recent years but is still below the target suggested by WHO. There is need to increase the cataract surgical rate in Yemen mainly in rural areas. Inadequate number of eye surgeons, limited accessibility of cataract surgical services in rural areas and the affordability of surgery to large sections of society are major constraints that have to be addressed. The information from this study will help and enable Ministry of Health and other eye care providers to more equitably disperse trained ophthalmic personnel and eye units in Yemeni governorates.

    To assess the potential use of a protein-based meningococcal group B (MenB) vaccine (Bexsero(®)) in addition to antibiotic chemoprophylaxis for preventing secondary cases. Published studies on the risk of secondary meningococcal infections were used to estimate the numbers needed to vaccinate (NNV) with Bexsero(®) to prevent a secondary case in household and educational settings. Most secondary cases occur within a few days of diagnosis in the index case. Unlike conjugate vaccines, early protection offered after a single dose of Bexsero(®) is likely to be low, particularly in young children, who are at higher risk of secondary infection. NNV was dependent on predicted meningococcal strain coverage, estimated onset of protection after one Bexsero(®) dose and estimated vaccine efficacy. Even in the most favourable scenario where we assume the vaccine is administered within 4 days of the index case and prevents 90% of cases occurring after 14 days, the NNV for household contacts was >1000. NNV in educational settings was much higher. The estimated NNV should be taken into account when deciding policy to recommend Bexsero(®) for close contacts of single cases in household or educational settings. Bexsero(®) may have a protective role in clusters and outbreaks. Copyright © 2014 The British Infection Association. Published by Elsevier Ltd. All rights reserved.

    Full Text Available Objective: To study the effect of ginkgo capsules combined with secondary preventive drugs on the endothelial injury and plaque properties of patients with hypertension complicated by carotid atherosclerosis. Methods: A total of 178 patients with hypertension complicated by carotid atherosclerosis who were treated in Chengyue Community Health Service Center of Xisaishan District Huangshi City Hubei Province between February 2015 and January 2017 were collected and randomly divided into two groups. Control group were treated with conventional secondary preventive drugs, and observation group were treated with ginkgo capsules combined with secondary preventive drugs. The differences in serum endothelial injury indexes and lipid metabolism indexes as well as carotid artery ultrasound parameters were compared between the two groups before and after treatment. Results: Before treatment, endothelial injury indexes and lipid metabolism indexes as well as carotid artery ultrasound parameters were not significantly different between two groups. After treatment, serum ET, AngⅡ, TC, LDL-C and LpA contents as well as carotid artery ultrasound parameters DS and AS levels of observation group were lower than those of control group while serum NO and HDL-C contents as well as carotid artery ultrasound parameter MLD level were higher than those of control group. Conclusion: Ginkgo capsule combined with secondary preventive drugs can effectively reduce the endothelial injury and stabilize the plaques in patients with hypertension complicated by carotid atherosclerosis.

    Prospective studies have not identified a viable pharmacologic strategy for secondary prevention of posttraumatic stress disorder (PTSD). The authors examined whether preventive intervention via early and short-term administration of a selective serotonin reuptake inhibitor (SSRI), within 1 month of exposure to a traumatic event (before diagnosis of PTSD could be made), may reduce the severity of PTSD symptoms according to DSM-IV at 13 months' follow-up. Over 25,000 screening calls to patients referred to an emergency department for a traumatic event performed between June 2006 and December 2008 yielded 353 participants who were recruited within the month following a traumatic event . Participants were randomly assigned in a double-blind design to escitalopram (n = 176) or placebo (n = 177). The per-protocol analysis comprised 198 participants (escitalopram, n = 102; placebo, n = 96) who received treatment for 12 to 24 weeks and were available for follow-up at week 56. The primary outcome measure, the Clinician Administered PTSD Scale (CAPS), revealed no prevention effect. However, a secondary outcome, the Pittsburgh Sleep Quality Inventory (PSQI), showed better results for the SSRI group than for the placebo group. For a subset of participants who experienced intentional trauma (missile attacks, rape, or physical assault; n = 50), the prevention effect was found on both primary and secondary measures (CAPS, PSQI and measures of depression and global illness severity). Early and short-term administration of escitalopram was not shown to prevent PTSD, although it did improve sleep quality. In a subgroup of participants who experienced intentional trauma, however, this early-treatment approach may be effective as secondary prevention. This large study is the first to investigate the preventive effect of early administration of escitalopram on PTSD. It highlights the relevance of the type of trauma (intentional vs unintentional) to the outcome. Clinical

    Human exploration of Mars is a key goal in NASA's exploration planning in the next 20 years. Maintaining crew health and good vision is certainly an important aspect of achieving a successful mission. Continuous radiation exposure is a risk factor for radiation-induced cataracts in astronauts because radiation exposure in space travel has the potential of accelerating the aging process (ref. 1). A patented compact device (ref. 2) based on the technique of dynamic light scattering (DLS) was designed for monitoring an astronaut's ocular health during long-duration space travel. This capability of early diagnosis, unmatched by any other clinical technique in use today, may enable prompt initiation of preventive/curative therapy. An Internet web-based system integrating photon correlation data and controlling the hardware to monitor cataract development in vivo at a remote site in real time (teleophthalmology) is currently being developed. The new technology detects cataracts very early (at the molecular level). Cataract studies onboard the International Space Station will be helpful in quantifying any adverse effect of radiation to ocular health. The normal lens in a human eye, situated behind the cornea, is a transparent tissue. It contains 35 wt % protein and 65 wt % water. Aging, disease (e.g., diabetes), smoking, dehydration, malnutrition, and exposure to ultraviolet light and ionizing radiation can cause agglomeration of the lens proteins. Protein aggregation can take place anywhere in the lens, causing lens opacity. The aggregation and opacification could produce nuclear (central portion of the lens) or cortical (peripheral) cataracts. Nuclear and posterior subcapsular (the membrane's capsule surrounds the whole lens) cataracts, being on the visual optical axis of the eye, cause visual impairment that can finally lead to blindness. The lens proteins, in their native state, are small in size. As a cataract develops, this size grows from a few nanometers

    Abstract Background: There is consensus that development and evaluation of a systems-oriented approach for child obesity prevention and treatment that includes both primary and secondary prevention efforts is needed. This article describes the study design and baseline data from the Texas Childhood Obesity Research Demonstration (TX CORD) project, which addresses child obesity among low-income, ethnically diverse overweight and obese children, ages 2–12 years; a two-tiered systems-oriented approach is hypothesized to reduce BMI z-scores, compared to primary prevention alone. Methods: Our study aims are to: (1) implement and evaluate a primary obesity prevention program; (2) implement and evaluate efficacy of a 12-month family-centered secondary obesity prevention program embedded within primary prevention; and (3) quantify the incremental cost-effectiveness of the secondary prevention program. Baseline demographic and behavioral data for the primary prevention community areas are presented. Results: Baseline data from preschool centers, elementary schools, and clinics indicate that most demographic variables are similar between intervention and comparison communities. Most families are low income (≤$25,000) and Hispanic/Latino (73.3–83.8%). The majority of parents were born outside of the United States. Child obesity rates exceed national values, ranging from 19.0% in preschool to 35.2% in fifth-grade children. Most parents report that their children consume sugary beverages, have a television in the bedroom, and do not consume adequate amounts of fruits and vegetables. Conclusions: Interventions to address childhood obesity are warranted in low-income, ethnically diverse communities. Integrating primary and secondary approaches is anticipated to provide sufficient exposure that will lead to significant decreases in childhood obesity. PMID:25555188

    Congenital cataracts and microphthalmia in the Miniature Schnauzer were inherited as an autosomal recessive trait. Eighteen matings of affected X affected Miniature Schnauzers resulted in 87 offspring with congenital cataracts and microphthalmia (49 males/38 females). Two matings of congenital cataractous and microphthalmic Miniature Schnauzers (2 females) X a normal Miniature Schnauzer (1 male) yielded 11 clinically normal Miniature Schnauzers (7 males/4 females). Eighteen matings of congenital cataractous and microphthalmic Miniature Schnauzers (6 males) X carrier Miniature Schnauzers (9 females) produced 81 offspring; 39 exhibited congenital cataracts and microphthalmia (20 males/19 females) and 42 had clinically normal eyes (17 males/25 females).

    Age-related cataract is a leading cause of visual impairment in the United States. The prevalence of age-related cataract is increasing, with an estimated 30.1 million Americans likely to be affected by 2020. To determine whether daily oral supplementation with lutein/zeaxanthin affects the risk for cataract surgery. The Age-Related Eye Disease Study 2 (AREDS2), a multicenter, double-masked clinical trial, enrolled 4203 participants, aged 50 to 85 years, at risk for progression to advanced age-related macular degeneration. Participants were randomly assigned to daily placebo; lutein/zeaxanthin, 10mg/2mg; omega-3 long-chain polyunsaturated fatty acids, 1 g; or a combination to evaluate the effects on the primary outcome of progression to advanced age-related macular degeneration. Cataract surgery was documented at annual study examination with the presence of pseudophakia or aphakia, or reported during telephone calls at 6-month intervals between study visits. Annual best-corrected visual acuity testing was performed. A secondary outcome of AREDS2 was to evaluate the effects of lutein/zeaxanthin on the subsequent need for cataract surgery. A total of 3159 AREDS2 participants were phakic in at least 1 eye and 1389 of 6027 study eyes underwent cataract surgery during the study, with median follow-up of 4.7 years. The 5-year probability of progression to cataract surgery in the no lutein/zeaxanthin group was 24%. For lutein/zeaxanthin vs no lutein/zeaxanthin, the hazard ratios for progression to cataract surgery was 0.96 (95% CI, 0.84-1.10; P = .54). For participants in the lowest quintile of dietary intake of lutein/zeaxanthin, the hazard ratio comparing lutein/zeaxanthin vs no lutein/zeaxanthin for progression to cataract surgery was 0.68 (95% CI, 0.48-0.96; P = .03). The hazard ratio for 3 or more lines of vision loss was 1.03 (95% CI, 0.93-1.13; P = .61 for lutein/zeaxanthin vs no lutein/zeaxanthin). Daily supplementation with lutein/zeaxanthin had no statistically

    Full Text Available A randomized single blinded clinical trial to compare the cost-effectiveness of cataract surgery between extracapsular cataract extraction (ECCE and phacoemulsification (PEA was conducted at Hospital Universiti Kebangsaan Malaysia (HUKM from March 2000 until August 2001. The cost of a cataract surgery incurred by hospital, patients and households were calculated preoperatively, one week, two months (for both techniques and six months (for ECCE only. Effectiveness of cataract surgery was assessed using Visual Function 14 (VF-14, quality of life measurement specifically for vision. The cost analysis results from each 50 subjects of ECCE and PEA group showed that average cost for one ECCE after six months post-operation is USD 458 (± USD 72 and for PEA is USD 528 (± USD 125. VF-14 score showed a significant increased after a week, two months and six months post-operation compared to the score before operation for both techniques (p<0.001. However, there was no significant difference between them (p = 0.225. This study indicated that ECCE is more cost effective compared to PEA with cost per one unit increment of VF-14 score of USD 14 compared to USD 20 for PEA.

    Purpose: To determine prospectively the cataract-free interval (latency time) after total body irradiation (TBI) and bone marrow transplantation (BMT) and to assess accurately the final severity of the cataract. Methods and Materials: Ninety-three of the patients who received TBI as a part of their conditioning regimen for BMT between 1982 and 1995 were followed with respect to cataract formation. Included were only patients who had a follow-up period of at least 23 months. TBI was applied in one fraction of 8 Gy or two fractions of 5 or 6 Gy. Cataract-free period was assessed and in 56 patients, who could be followed until stabilization of the cataract had occurred, final severity of the cataract was determined using a classification system. With respect to final severity, two groups were analyzed: subclinical low-grade cataract and high-grade cataract. Cataract-free period and final severity were determined with respect to type of transplantation, TBI dose, and posttransplant variables such as graft versus host disease (GVHD) and steroid treatment. Results: Cataract incidence of the analyzed patients was 89%. Median time to develop a cataract was 58 months for autologous transplanted patients. For allogeneic transplanted patients treated or not treated with steroids, median times were 33 and 46 months, respectively. Final severity was not significantly different for autologous or allogeneic patients. In allogeneic patients, however, final severity was significantly different for patients who had or had not been treated with steroids for GVHD: 93% versus 35% high-grade cataract, respectively. Final severity was also different for patients receiving 1 x 8 or 2 x 5 Gy TBI, from patients receiving 2 x 6 Gy as conditioning therapy: 33% versus 79% high-grade cataract, respectively. The group of patients receiving 2 x 6 Gy comprised, however, more patients with steroid treatment for GVHD. So the high percentage of high-grade cataract in the 2 x 6 Gy group might also

    Full Text Available BACKGROUND Traumatic cataract is common presentation of penetrating and blunt ocular trauma in children. Ocular trauma is the leading cause of unilateral blindness all over the world. The incidence of ocular trauma varies in different parts of the world. From India, the reported incidence is 20.53%. Traumatic cataract causes significant blindness in paediatric populations particularly in developing countries. The aim of the study is to evaluate the final visual outcome of the patients with traumatic cataract. MATERIALS AND METHODS We conducted a prospective study of 100 children from 4 to 16 years of age presenting in Outpatient Department of Regional Institute of Ophthalmology, Kolkata, with traumatic cataract between April 2015 to March 2017. Detailed history, systemic and local examinations and relevant investigations done followed by medical and surgical intervention and patients were followed up till six months and final visual acuity recorded. RESULTS There was a male predilection with a male-to-female ratio 2.85:1.56 (56% patients sustained penetrating trauma, while 44 (44% were inflicted with blunt injury. Commonest causative agent was trauma with organic foreign bodies in 20 eyes (20% followed by stones in 14 eyes (14%. Anterior segment was more involved than posterior segment. Final best corrected visual acuity after six months was better than or equal to 6/18 in 64 eyes (64%. The major early postoperative complications include anterior uveitis in 26 (26% and corneal oedema in 8 (8% patients, while late postoperative complication was posterior capsular uveitis in 36% patients. CONCLUSION Paediatric traumatic cataract can cause ocular morbidity. Timely and proper medical and surgical intervention can result in good visual outcome. The parents, caretakers and teachers have an important role to play in prevention by recognising hazardous situation and taking preventing measures.

    To describe current cataract surgery practices within the United States Veterans Health Administration (VHA). Veterans Health Administration hospitals in the U.S. Retrospective data analysis. An initial e-mail containing a link to an anonymous 32-question survey of cataract surgery practices was sent to participants in May 2016. Two reminder e-mails were sent to nonresponders 1 week and 2 weeks after the initial survey was sent; the remaining nonresponders were called twice over a 2-week period. The data were analyzed using descriptive statistics. The response rate was 75% (67/89). Cataract surgeons routinely ordered preoperative testing in 29 (45%) of 65 sections and preoperative consultations in 26 (39%) of 66 sections. In 22 (33%) of 66 sections, cataract surgeons administered intracameral antibiotics. In 61 (92%) of 66 sections, cataract surgeons used toric intraocular lenses (IOLs). In 20 (30%) of 66 sections, cataract surgeons used multifocal IOLs. Cataract surgeons in 6 (9%) of 66 sections performed femtosecond laser-assisted cataract surgery. In 6 (9%) of 66 sections, cataract surgeons performed immediate sequential bilateral cataract surgery. Forty-nine (74%) ophthalmology chiefs reported a high level of satisfaction with Veterans Affairs ophthalmology. The survey results indicate that in cataract surgery in the VHA, routine preoperative testing is commonly performed and emerging practices, such as femtosecond laser-assisted cataract surgery and immediate sequential bilateral cataract surgery, have limited roles. The results of this survey could benchmark future trends in U.S. cataract surgery practices, especially in teaching hospital settings. Copyright © 2017 ASCRS and ESCRS. Published by Elsevier Inc.

    An outbreak of cataracts in 1935 caused by dinitrophenol (DNP), the active ingredient of popular diet pills, highlighted the inability of the U.S. Food and Drug Administration (FDA) to prevent harmful drugs from entering the marketplace. Just two years earlier, the FDA used horrific images of ocular surface injury caused by cosmetics at the World's Fair in Chicago to garner public support for legislative reform. The FDA had to walk a fine line between a public awareness campaign and lobbying Congress while lawmakers debated the need for consumer protection. The cataract outbreak of 1935 was conspicuous in the medical literature during the height of New Deal legislation, but questions persist as to how much it affected passage of the proposed Food, Drug, and Cosmetic Act (of 1938). The legislation languished in committee for years. The cataract outbreak probably had little impact on the eventual outcome, but medical opinion concerning the safety of DNP may have contributed to the voluntary withdrawal of the diet drug from the market. We review the DNP cataract outbreak and examine it in context of the challenges facing regulatory reform at that time. Copyright © 2014 Elsevier Inc. All rights reserved.

    Objective: To evaluate the impact of different intervention models on adherence to secondary prevention therapies in patients with acute coronary syndrome (ACS). Methods: This multi-center cross-sectional study collected data from 34 hospitals covering 22 provinces in China. Hospitals were randomly divided into four groups: control group(routine treatment and care), promotional calendar group (routine treatment and care plus giving propaganda desk calendar to patients), education group (routine treatment and care add patients education by nurses) and combined intervention group (promotional calendar and education).At least 90 patients with ACS were consecutively enrolled from each involved hospital from April 15, 2012 to June 30, 2013. To reduce the impact of uneven distribution of inter-group variables on the results, 1∶1∶1∶1 propensity score matching method was used. The drug usage for secondary prevention and prognosis wasobtainedat 6 months after hospital discharge. Results: (1) A total of 3 391 patients were selected and 2 244 patients were included for the final analysisafter propensity score analysis. (2) At 6 months after discharge, the adherence rates of antiplatelet, statins, angiotensin converting enzyme inhibitor(ACEI)/angiotensin Ⅱ receptor blocker(ARB), β-blocker and the combination of 4 medications were similar between control group and promotional calendar group (all P> 0.016).The adherence rates of antiplatelet and statins were 97.0% (526/542) and 91.0% (493/542) in the education group, 3.7% and 5.5% higher than in the control group (both Ppromotional calendar group, and the statins adherence rate was 5.5%( OR= 1.055, 95% CI 1.012-1.101, Ppromotional calendar group, respectively, and statin adherence was 6.1% ( OR= 1.061, 95% CI 1.017-1.107, Ppromotional calendar group and education group.

    To determine the perception of Primary Care (PC) physicians on the integration with cardiology (CA) through continuity of healthcare programs. A cross-sectional and multicentre study was conducted, in which a total of 200 PC physicians from all over Spain completed a qualitative survey that evaluated the level of integration with CA in secondary prevention. Physicians were grouped according to the level of PC-CA integration. The integration between CA and PC was good, but it was better in those centres with a higher integration (74.0% vs. 60.0%; p=.02) and in general, physicians considered that integration had improved (92.0% vs. 73.0%; pintegration. In 55.8%, 63.6%, and 51.3% of hospital discharge reports, indications were given on when to perform the follow-up blood analysis, as well as information about returning to working life and sexual activity, respectively. The most common communication method was the paper-based report (75 vs. 84%; p=NS). The communication between healthcare levels was greater in those Primary Care centres with a higher level of integration, as well as periodicity of the communication and the satisfaction of physicians (80.0% vs. 63.0%; p=.005). The level of integration between PC and CA is, in general, satisfactory, but those centres with a higher level of integration benefit more from a greater communication and satisfaction.

    Joshua Byrnes

    Full Text Available The aim of this study is to consider the cost-effectiveness of a nurse-led, home-based intervention (HBI in cardiac patients with private health insurance compared to usual post-discharge care. A within trial analysis of the Young @ Heart multicentre, randomized controlled trial along with a micro-simulation decision analytical model was conducted to estimate the incremental costs and quality adjusted life years associated with the home based intervention compared to usual care. For the micro-simulation model, future costs, from the perspective of the funder, and effects are estimated over a twenty-year time horizon. An Incremental Cost-Effectiveness Ratio, along with Incremental Net Monetary Benefit, is evaluated using a willingness to pay threshold of $50,000 per quality adjusted life year. Sub-group analyses are conducted for men and women across three age groups separately. Costs and benefits that arise in the future are discounted at five percent per annum. Overall, home based intervention for secondary prevention in patients with chronic heart disease identified in the Australian private health care sector is not cost-effective. The estimated within trial incremental net monetary benefit is -$3,116 [95% CI: -11,145, $4,914]; indicating that the costs outweigh the benefits. However, for males and in particular males aged 75 years and above, home based intervention indicated a potential to reduce health care costs when compared to usual care (within trial: -$10,416 [95% CI: -$26,745, $5,913]; modelled analysis: -$1,980 [95% CI: -$22,843, $14,863]. This work provides a crucial impetus for future research to understand for whom disease management programs are likely to benefit most.

    Full Text Available Following decades of civil disturbance in Cambodia, by the early 1990s there were few doctors remaining in the country, and little in the way of eye care services.With NGO support, training centres were established to train medical graduates and nurses as ‘basic eye doctors’ and ‘basic eye nurses’. These workers were then placed in provincial eye units to serve the eye care needs of those provinces. However, it soon became clear that, despite evidence that blindness, including cataract blindness, was prevalent, patients were not attending these provincial eye units. Attention was therefore given to finding out more about the barriers preventing patients benefiting from these services.

    Supplementation of cataract patients with multifocal intraocular lenses involves an additional financial investment when compared to the corresponding monofocal supplementation, which usually is not funded by German health care insurers. In the context of recent resource allocation discussions, however, the cost effectiveness of multifocal cataract surgery could become an important rationale. Therefore an evidence-based estimation of its cost effectiveness was carried out. Three independent meta-analyses were implemented to estimate the gain in uncorrected near visual acuity and best corrected visual acuity (vision lines) as well as the predictability (fraction of patients without need for reading aids) of multifocal supplementation. Study reports published between 1995 and 2004 (English or German language) were screened for appropriate key words. Meta effects in visual gain and predictability were estimated by means and standard deviations of the reported effect measures. Cost data were estimated by German DRG rates and individual lens costs; the cost effectiveness of multifocal cataract surgery was then computed in terms of its marginal cost effectiveness ratio (MCER) for each clinical benefit endpoint; the incremental costs of multifocal versus monofocal cataract surgery were further estimated by means of their respective incremental cost effectiveness ratio (ICER). An independent meta-analysis estimated the complication profiles to be expected after monofocal and multifocal cataract surgery in order to evaluate expectable complication-associated additional costs of both procedures; the marginal and incremental cost effectiveness estimates were adjusted accordingly. A sensitivity analysis comprised cost variations of +/- 10 % and utility variations alongside the meta effect estimate's 95 % confidence intervals. Total direct costs from the health care insurer's perspective were estimated 3363 euro, associated with a visual meta benefit in best corrected visual

    Violence against women (VAW) is a major problem worldwide, with one in three women experiencing violence in their lifetime. While interventions to prevent violence (primary prevention) are extremely important, they can take many years. This review focuses on secondary and tertiary prevention interventions that address the needs of survivors of violence and aim to prevent recurrence. This review also focuses on studies taking place in low and low-middle income countries, where rates of VAW are highest. Searches of peer-reviewed and grey literature took place from March-June 2016 through databases (Embase, CINAHL, WHO Global Index Medicus, Medline, PsychINFO, Web of Science, Cochrane Library, Applied Social Sciences Index and Abstracts and Sociological Abstracts) and by consulting experts in the field. Only primary research was eligible for inclusion and studies had to focus on secondary or tertiary prevention for survivors of VAW in low or low-middle income countries. All study designs were eligible, as long as the study examined client-related outcome measures (e.g., incidence of violence, health outcomes or client satisfaction). Data were extracted and quality of the studies was assessed using the Effective Public Health Practice Project Quality Assessment Tool for Quantitative Studies and a qualitative quality assessment tool developed by Mays and Pope. Due to the low number of results and heterogeneity of the study populations and outcomes, a narrative synthesis was conducted and evidence was summarized. One thousand two hundred fifteen studies were identified through the search strategy and 22 of these met the eligibility criteria. Overall, the evidence for interventions is weak and study limitations prevent definitive conclusions on what works. There is some evidence that interventions targeting alcohol use, both among perpetrators and survivors, may be effective at reducing VAW through secondary prevention, and that psychotherapy might be effective for

    A 78-year-old woman with rheumatoid arthritis and secondary Sjögren's syndrome presented with corneal melting three days after cataract extraction that required penetrating keratoplasty. By the fourth month, a second corneal transplant was needed due to a new descemetocele associated with her systemic disease. The underlying disease, together with the surgical history, was responsible for the complication presented. The correct anamnesis prior to cataract surgery, a refined technique, and a close post-operative follow-up can avoid such a serious complication. Immunomodulatory treatments are essential in this type of patient. Copyright © 2017 Sociedad Española de Oftalmología. Publicado por Elsevier España, S.L.U. All rights reserved.

    To identify factors associated prospectively with increased cataract surgical rate (CSR) in rural Chinese hospitals. Annual cataract surgical output was obtained at baseline and 24 months later from operating room records at 42 rural, county-level hospitals. Total local CSR (cases/million population/y), and proportion of CSR from hospital and local competitors were calculated from government records. Hospital administrators completed questionnaires providing demographic and professional information, and annual clinic and outreach screening volume. Independent cataract surgeons provided clinical information and videotapes of cases for grading by two masked experts using the Ophthalmology Surgical Competency Assessment Rubric (OSCAR). Uncorrected vision was recorded for 10 consecutive cataract cases at each facility, and 10 randomly-identified patients completed hospital satisfaction questionnaires. Total value of international nongovernmental development organization (INGDO) investment in the previous three years and demographic information on hospital catchment areas were obtained. Main outcome was 2-year percentage change in hospital CSR. Among the 42 hospitals (median catchment population 530,000, median hospital CSR 643), 78.6% (33/42) were receiving INGDO support. Median change in hospital CSR (interquartile range) was 33.3% (-6.25%, 72.3%). Predictors of greater increase in CSR included higher INGDO investment (P = 0.02, simple model), reducing patient dissatisfaction (P = 0.03, simple model), and more outreach patient screening (P = 0.002, simple and multiple model). Outreach cataract screening was the strongest predictor of increased surgical output. Government and INGDO investment in screening may be most likely to enhance output of county hospitals, a major goal of China's Blindness Prevention Plan.

    The purpose of this study was to investigate the effect of curcumin and its source, turmeric, on streptozotocin-induced diabetic cataract in rats. Wistar-NIN rats were selected and diabetes was induced by streptozotocin (35 mg/kg body weight, intraperitoneally) and divided into four groups (group II-V). The control (group I) rats received only vehicle. Group I and II animals received an unsupplemented AIN-93 diet, and those in groups III, IV, and V received 0.002% and 0.01% curcumin and 0.5% turmeric, respectively, in an AIN-93 diet for a period of 8 weeks. Cataract progression due to hyperglycemia was monitored by slit lamp biomicroscope and classified into four stages. At the end of 8 weeks, the animals were killed and the biochemical pathways involved in the pathogenesis of cataract such as oxidative stress, polyol pathway, alterations in protein content and crystallin profile in the lens were investigated, to understand the possible mechanism of action of curcumin and turmeric. Blood glucose and insulin levels were also determined. Although, both curcumin and turmeric did not prevent streptozotocin-induced hyperglycemia, as assessed by blood glucose and insulin levels, slit lamp microscope observations indicated that these supplements delayed the progression and maturation of cataract. The present studies suggest that curcumin and turmeric treatment appear to have countered the hyperglycemia-induced oxidative stress, because there was a reversal of changes with respect to lipid peroxidation, reduced glutathione, protein carbonyl content and activities of antioxidant enzymes in a significant manner. Also, treatment with turmeric or curcumin appears to have minimized osmotic stress, as assessed by polyol pathway enzymes. Most important, aggregation and insolubilization of lens proteins due to hyperglycemia was prevented by turmeric and curcumin. Turmeric was more effective than its corresponding levels of curcumin. The results indicate that turmeric and curcumin

    Background The incidence of melanoma is increasing faster than any other major cancer both in Brazil and worldwide. Southeast Brazil has especially high incidences of melanoma, and early detection is low. Exposure to ultraviolet (UV) radiation is a primary risk factor for developing melanoma. Increasing attractiveness is a major motivation among adolescents for tanning. A medical student-delivered intervention that takes advantage of the broad availability of mobile phones and adolescents’ interest in their appearance indicated effectiveness in a recent study from Germany. However, the effect in a high-UV index country with a high melanoma prevalence and the capability of medical students to implement such an intervention remain unknown. Objective In this pilot study, our objective was to investigate the preliminary success and implementability of a photoaging intervention to prevent skin cancer in Brazilian adolescents. Methods We implemented a free photoaging mobile phone app (Sunface) in 15 secondary school classes in southeast Brazil. Medical students “mirrored” the pupils’ altered 3-dimensional (3D) selfies reacting to touch on tablets via a projector in front of their whole grade accompanied by a brief discussion of means of UV protection. An anonymous questionnaire capturing sociodemographic data and risk factors for melanoma measured the perceptions of the intervention on 5-point Likert scales among 356 pupils of both sexes (13-19 years old; median age 16 years) in grades 8 to 12 of 2 secondary schools in Brazil. Results We measured more than 90% agreement in both items that measured motivation to reduce UV exposure and only 5.6% disagreement: 322 (90.5%) agreed or strongly agreed that their 3D selfie motivated them to avoid using a tanning bed, and 321 (90.2%) that it motivated them to improve their sun protection; 20 pupils (5.6%) disagreed with both items. The perceived effect on motivation was higher in female pupils in both tanning bed

    Despite establishment of advocacies centered on using patient-centered care to improve disease-related behavioral changes and health outcomes, studies have seldom discussed incorporation of patient-centered care concept in the design of secondary cardiac prevention. This review aimed to identify, appraise, and examine existing evidence on the effectiveness of nurse-led patient-centered care for secondary cardiac prevention in patients with coronary heart disease. A systematic review of randomized controlled trials focusing on nurse-led patient-centered care for secondary cardiac prevention was conducted. Primary outcomes were behavioral risks (e.g. smoking, physical activity), secondary outcomes were clinically relevant physiological parameters (e.g. body weight, blood pressure, blood glucose, blood lipoproteins), health-related quality of life, mortality, and self efficacy. Twenty-three English and seven Chinese electronic databases were searched to identify the trials. The studies' eligibility and methodological quality were assessed by two reviewers independently according to the Joanna Briggs Institute guidelines. Statistical heterogeneities of the included studies were assessed by Higgins I2 and quantitative pooling was performed when studies showed sufficient comparability. 15 articles on 12 randomized controlled trials were included in this review. Methodological quality of the included studies was fair. Based on the Joanna Briggs Institute critical appraisal tool for experimental studies, the included studies had met a mean of six criteria out the ten in this appraisal tool. The meta-analyses of the included studies revealed that nurse-led patient-centered care had significantly improved patients' smoking habits, adherence toward physical activity advices, and total cholesterol level with medical regime optimization, in short- to medium-term. The intervention was also favorable in improving the patients' health-related quality of life in several domains of

    Full Text Available Cataract refers to the degenerative changes in lens quality caused by various causes of reduced transparency or color change. Surgical treatment is the main treatment modality at present. Among them, phacoemulsification has become the main surgical treatment for cataract because of its advantages such as short operation time, small incision and quicker healing. Today, cataract surgery has gradually shift to refractive surgery, and is no longer simply as cataract surgery. But after cataract phacoemulsification, the symptoms and visual quality are different. The main causes include refractive error, postoperative dry eyes and postoperative corneal astigmatism. This article reviews the factors that influence the visual quality of cataract phacoemulsification and its future trends.

    Full Text Available Abstract Background Patients with recent stroke or TIA are at high risk for new vascular events. Several evidence based strategies in secondary prevention of stroke are available but frequently underused. Support programs with multifactorial risk factor modifications after stroke or TIA have not been investigated in large-scale prospective controlled trials so far. INSPiRE-TMS is a prospective, multi-center, randomized open intervention trial for intensified secondary prevention after minor stroke and TIA. Methods/design Patients with acute TIA or minor stroke admitted to the participating stroke centers are screened and recruited during in-hospital stay. Patients are randomised in a 1:1 ratio to intervention (support program and control (usual care arms. Inclusion of 2.082 patients is planned. The support program includes cardiovascular risk factor measurement and feedback, monitoring of medication adherence, coaching in lifestyle modifications, and active involvement of relatives. Standardized motivational interviewing is used to assess and enhance patients’ motivation. Primary objective is a reduction of new major vascular events defined as nonfatal stroke and myocardial infarction or vascular death. Recruitment time is planned for 3.5 years, follow up time is at least 2 years for every patient resulting in a total study time of 5 years (first patient in to last patient out. Discussion Given the high risk for vascular re-events in acute stroke and the available effective strategies in secondary prevention, the INSPIRE-TMS support program has the potential to lead to a relevant reduction of recurrent events and a prolongation of the event-free survival time. The trial will provide the basis for the decision whether an intensified secondary prevention program after stroke should be implemented into regular care. A cost-effectiveness evaluation will be performed. Trial registration clinicaltrials.gov: 01586702

    Fracture Liaison Services are the best model to prevent secondary fractures. The International Osteoporosis Foundation developed a Best Practice Framework to provide a quality benchmark. After a year of implementation, we confirmed that a single framework with set criteria is able to benchmark services across healthcare systems worldwide. Despite evidence for the clinical effectiveness of secondary fracture prevention, translation in the real-world setting remains disappointing. Where implemented, a wide variety of service models are used to deliver effective secondary fracture prevention. To support use of effective models of care across the globe, the International Osteoporosis Foundation's Capture the Fracture® programme developed a Best Practice Framework (BPF) tool of criteria and standards to provide a quality benchmark. We now report findings after the first 12 months of implementation. A questionnaire for the BPF was created and made available to institutions on the Capture the Fracture website. Responses from institutions were used to assign gold, silver, bronze or black (insufficient) level of achievements mapped across five domains. Through an interactive process with the institution, a final score was determined and published on the Capture the Fracture website Fracture Liaison Service (FLS) map. Sixty hospitals across six continents submitted their questionnaires. The hospitals served populations from 20,000 to 15 million and were a mix of private and publicly funded. Each FLS managed 146 to 6200 fragility fracture patients per year with a total of 55,160 patients across all sites. Overall, 27 hospitals scored gold, 23 silver and 10 bronze. The pathway for the hip fracture patients had the highest proportion of gold grading while vertebral fracture the lowest. In the first 12 months, we have successfully tested the BPF tool in a range of health settings across the globe. Initial findings confirm a significant heterogeneity in service provision and

    Patent foramen ovale closure represents a potential secondary prevention strategy for cryptogenic stroke, but available trials have varied by size, device studied, and follow-up. We conducted a systematic search of published randomized clinical trials evaluating patent foramen ovale closure versus medical therapy in patients with recent stroke or transient ischemic attack using PubMED, EMBASE, and Cochrane through September 2017. Weighting was by random effects models. Of 480 studies screened, we included 5 randomized clinical trials in the meta-analysis in which 3440 patients were randomized to patent foramen ovale closure (n = 1829) or medical therapy (n = 1611) and followed for an average of 2.0 to 5.9 years. Index stroke/transient ischemic attack occurred within 6 to 9 months of randomization. The primary end point was composite stroke/transient ischemic attack and death (in 3 trials) or stroke alone (in 2 trials). Patent foramen ovale closure reduced the primary end point (0.70 vs 1.48 events per 100 patient-years; risk ratio [RR], 0.52 [0.29-0.91]; I 2  = 55.0%) and stroke/transient ischemic attack (1.04 vs 2.00 events per 100 patient-years; RR, 0.55 [0.37-0.82]; I 2  = 42.2%) with modest heterogeneity compared with medical therapy. Procedural bleeding was not different between study arms (1.8% vs 1.8%; RR, 0.94 [0.49-1.83]; I 2  = 29.2%), but new-onset atrial fibrillation/flutter was increased with patent foramen ovale closure (6.6% vs 0.7%; RR, 4.69 [2.17-10.12]; I 2  = 29.3%). In patients with recent cryptogenic stroke, patent foramen ovale closure reduces recurrent stroke/transient ischemic attack compared with medical therapy, but is associated with a higher risk of new-onset atrial fibrillation/flutter.

    2014-02-01

    Virtual simulators have been widely implemented in medical and surgical training, including ophthalmology. The increasing number of published articles in this field mandates a review of the available results to assess current technology and explore future opportunities. A PubMed search was conducted and a total of 10 articles were reviewed. Virtual simulators have shown construct validity in many modules, successfully differentiating user experience levels during simulated phacoemulsification surgery. Simulators have also shown improvements in wet-lab performance. The implementation of simulators in the residency training has been associated with a decrease in cataract surgery complication rates. Virtual reality simulators are an effective tool in measuring performance and differentiating trainee skill level. Additionally, they may be useful in improving surgical skill and patient outcomes in cataract surgery. Future opportunities rely on taking advantage of technical improvements in simulators for education and research.

    Pelvic floor muscle training can reduce prolapse severity and symptoms in women seeking treatment. We aimed to assess whether this intervention could also be effective in secondary prevention of prolapse and the need for future treatment. We did this multicentre, parallel-group, randomised controlled trial at three centres in New Zealand and the UK. Women from a longitudinal study of pelvic floor function after childbirth were potentially eligible for inclusion. Women of any age who had stage 1-3 prolapse, but had not sought treatment, were randomly assigned (1:1), via remote computer allocation, to receive either one-to-one pelvic floor muscle training (five physiotherapy appointments over 16 weeks, and annual review) plus Pilates-based pelvic floor muscle training classes and a DVD for home use (intervention group), or a prolapse lifestyle advice leaflet (control group). Randomisation was minimised by centre, parity (three or less vs more than three deliveries), prolapse stage (above the hymen vs at or beyond the hymen), and delivery method (any vaginal vs all caesarean sections). Women and intervention physiotherapists could not be masked to group allocation, but allocation was masked from data entry researchers and from the trial statistician until after database lock. The primary outcome was self-reported prolapse symptoms (Pelvic Organ Prolapse Symptom Score [POP-SS]) at 2 years. Analysis was by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT01171846. Between Dec 21, 2008, and Feb 24, 2010, in New Zealand, and Oct 27, 2010, and Sept 5, 2011, in the UK, we randomly assigned 414 women to the intervention group (n=207) or the control group (n=207). One participant in each group was excluded after randomisation, leaving 412 women for analysis. At baseline, 399 (97%) women had prolapse above or at the level of the hymen. The mean POP-SS score at 2 years was 3·2 (SD 3·4) in the intervention group versus 4·2 (SD 4·4) in the

  2. Individual preferences for physical exercise as secondary prevention for non-specific low back pain: A discrete choice experiment.

    Full Text Available Exercise is effective in improving non-specific low back pain (LBP. Certain components of physical exercise, such as the type, intensity and frequency of exercise, are likely to influence participation among working adults with non-specific LBP, but the value and relative importance of these components remain unknown. The study's aim was to examine such specific components and their influence on individual preferences for exercise for secondary prevention of non-specific LBP among working adults.In a discrete choice experiment, working individuals with non-specific LBP answered a web-based questionnaire. Each respondent was given ten pairs of hypothetical exercise programs and asked to choose one option from each pair. The choices comprised six attributes of exercise (i.e., type of training, design, intensity, frequency, proximity and incentives, each with either three or four levels. A conditional logit regression that reflected the random utility model was used to analyze the responses.The final study population consisted of 112 participants. The participants' preferred exercise option was aerobic (i.e., cardiovascular rather than strength training, group exercise with trainer supervision, rather than individual or unsupervised exercise. They also preferred high intensity exercise performed at least once or twice per week. The most popular types of incentive were exercise during working hours and a wellness allowance rather than coupons for sports goods. The results show that the relative value of some attribute levels differed between young adults (age ≤ 44 years and older adults (age ≥ 45 years in terms of the level of trainer supervision required, exercise intensity, travel time to exercise location and financial incentives. For active study participants, exercise frequency (i.e., twice per week, 1.15; CI: 0.25; 2.06 influenced choice of exercise. For individuals with more than one child, travel time (i.e., 20 minutes, -0.55; CI: 0

    Oral healthcare providers have a clinical opportunity for early detection of disordered eating behaviors because they are often the first health professionals to observe overt oral and physical signs. Curricula regarding early recognition of this oral/systemic medical condition are limited in oral health educational programs. Web-based learning can supplement and reinforce traditional learning and has the potential to develop skills. The study purpose was to determine the efficacy of a theory-driven Web-based training program to increase the capacity of oral health students to perform behaviors related to the secondary prevention of disordered eating behaviors. Using the Reach, Effectiveness, Adoption, Implementation and Maintenance evaluation framework, a longitudinal group-randomized controlled trial involving 27 oral health classes from 12 oral health education programs in the United States was implemented to assess the efficacy of the Web-based training on attitudes, knowledge, self-efficacy and skills related to the secondary prevention of disordered eating behaviors. Mixed-model analysis of covariance indicated substantial improvements among students in the intervention group (effect sizes: 0.51-0.83) on all six outcomes of interest. Results suggest that the Web-based training program may increase the capacity of oral healthcare providers to deliver secondary prevention of disordered eating behaviors. Implications and value of using the Reach, Effectiveness, Adoption, Implementation and Maintenance framework are discussed.

    To characterize cataract and its surgery among adults aged ≥40 years in Fiji. Population-based cross-sectional survey using multistage cluster random sampling. 1381 (= 73.0% participation); eight provinces on Viti Levu. Interview-based questionnaire; visual acuity measured; autorefraction; dilated ocular examination. Prevalence; predictors; surgical outcomes. Being Indian (P = 0.001), elderly (P Fiji population aged ≥40 years, prevalence of cataract-induced low vision and blindness were each 1.7% (95% confidence interval [CI] 1.0-2.4%). At least one eye of 4.6% and both of 1.8% participants had surgery (86.4% extracapsular). Gender (P = 0.213), age (P = 0.472) and rural/urban domicile (P = 0.895) were not predictors of surgery among those who required it in at least one eye. After intraocular lens surgery: 50.7% had pupillary posterior capsular opacification; mean spherical equivalent was -1.37 ± 1.95D (range, -6.38 to +2.25D); mean cylindrical error was 2.31 ± 1.75D (range, 0.0 to 8.75D); ≥N8 for 39.5%; ≥6/18 for 56.6%; Fiji population aged ≥40 years, Cataract Surgical Coverage (Person) was 47.5% (95%CI 29.2-65.8%) at Fiji cataract services and outcomes compare favourably with those of neighbouring Papua New Guinea and Timor Leste. © 2011 The Authors.

    Decreasing vision due to cataracts became a significant problem for Queen Victoria toward the end of the 19th century. Her personal physician, Sir James Reid, obtained consultations with two eminent British ophthalmologists, George Lawson and Edward Nettleship. The Queen was not satisfied, and requested an opinion from the German professor Hermann Pagenstecher. All the doctors agreed on the diagnosis, but the Queen never underwent surgery.

    This paper presents the experimental study revealing weaker performance of the automatic iris recognition methods for cataract-affected eyes when compared to healthy eyes. There is little research on the topic, mostly incorporating scarce databases that are often deficient in images representing more than one illness. We built our own database, acquiring 1288 eye images of 37 patients of the Medical University of Warsaw. Those images represent several common ocular diseases, such as cataract, along with less ordinary conditions, such as iris pattern alterations derived from illness or eye trauma. Images were captured in near-infrared light (used in biometrics) and for selected cases also in visible light (used in ophthalmological diagnosis). Since cataract is a disorder that is most populated by samples in the database, in this paper we focus solely on this illness. To assess the extent of the performance deterioration we use three iris recognition methodologies (commercial and academic solutions) to calculate genuine match scores for healthy eyes and those influenced by cataract. Results show a significant degradation in iris recognition reliability manifesting by worsening the genuine scores in all three matchers used in this study (12% of genuine score increase for an academic matcher, up to 175% of genuine score increase obtained for an example commercial matcher). This increase in genuine scores affected the final false non-match rate in two matchers. To our best knowledge this is the only study of such kind that employs more than one iris matcher, and analyzes the iris image segmentation as a potential source of decreased reliability

    To assess the prevalence and causes of avoidable blindness in Atsinanana Region, Madagascar, with the Rapid Assessment of Avoidable Blindness (RAAB) survey. We analyzed the hospital records to supplement the findings for public health care planning. Only villages within a two-hour walk from a road, about half of the population of Atsinanana was included. Seventy-two villages were selected by population-proportional-to-size sampling. In each village, compact segment sampling was used to select 50 people over age 50 for eye examination using standard RAAB methods. Records at the two hospitals providing cataract surgery in the region were analyzed for information on patients who underwent cataract surgery in 2010. Cataract incidence rate and target cataract surgery rate (CSR) was modeled from age-specific prevalence of cataract. The participation rate was 87% and the sample prevalence of blindness was 1.96%. Cataract was responsible for 64% and 85.7% of blindness and severe visual impairment, respectively. Visual impairment was due to cataract (69.4%) and refractive error (14.1%). There was a strong positive correlation between cataract surgical rate by district and the proportion of people living within 2 hours of a road. There were marked differences in the profiles of the cataract patients at the two facilities. The estimated incidence of cataract at the 6/18 level was 2.4 eyes per 100 people over age 50 per year. Although the survey included only people with reasonable access, the main cause of visual impairment was still cataract. The incidence of cataract is such that it ought to be possible to eliminate it as a cause of visual impairment, but changes in service delivery at hospitals and strategies to improve access will be necessary for this change.

    Full Text Available Cataract surgery is one of the most successful and frequently performed operations worldwide, and yet cataract remains the commonest cause of global blindness. This is in part due to the shortage and uneven distribution of trained personnel in some countries. More worryingly, a high rate of cataract blindness also reflects poor visual outcomes after surgery, as has been documented in many RAAB (rapid assessment of avoidable blindness studies.

    Full Text Available BACKGROUND: Radiation cataracts develop as a consequence of the effects of ionizing radiation on the development of the lens of the eye with an opaque lens reducing or eliminating the ability to see. Therefore, we would expect cataracts to be associated with reduced fitness in free-living animals. METHODOLOGY/PRINCIPAL FINDINGS: We investigated the incidence of lens opacities typical of cataracts in more than 1100 free-living birds in the Chernobyl region in relation to background radiation. The incidence of cataracts increased with level of background radiation both in analyses based on a dichotomous score and in analyses of continuous scores of intensity of cataracts. The odds ratio per unit change in the regressor was 0.722 (95% CI 0.648, 0.804, which was less than odds ratios from investigations of radiation cataracts in humans. The relatively small odds ratio may be due to increased mortality in birds with cataracts. We found a stronger negative relationship between bird abundance and background radiation when the frequency of cataracts was higher, but also a direct effect of radiation on abundance, suggesting that radiation indirectly affects abundance negatively through an increase in the frequency of cataracts in bird populations, but also through direct effects of radiation on other diseases, food abundance and interactions with other species. There was no increase in incidence of cataracts with increasing age, suggesting that yearlings and older individuals were similarly affected as is typical of radiation cataract. CONCLUSIONS/SIGNIFICANCE: These findings suggest that cataracts are an under-estimated cause of morbidity in free-living birds and, by inference, other vertebrates in areas contaminated with radioactive materials.

    Cataract and insufficient vitamin D intake are both increasing worldwide concerns, yet little is known about the relationship between serum 25-hydroxyvitamin D (25(OH)D) levels and age-related cataract. We performed this study to determine the association between serum 25(OH)D levels and age-related cataract in adults. Study participants comprised 16,086 adults aged 40 years or older who had never been diagnosed with or undergone surgery for cataract using Korean National Health and Nutrition Examination Survey data from 2008 to 2012. Participants were assessed to have cataract when diagnosed with cortical, nuclear, anterior subcapsular, posterior subcapsular, or mixed cataract. Odds ratios (ORs) and 95% confidence intervals (CIs) were used to evaluate the magnitude and significance of the association between serum 25(OH)D levels and cataract in multivariable logistic regression models. The OR for nuclear cataract with the highest quintile of serum 25(OH)D levels was 0.86 (95% CI 0.75-0.99) compared to the lowest quintile. A linear trend across quintiles was significant. Natural log-transformed serum 25(OH)D levels were also significantly associated with nuclear cataract (OR 0.84, 95% CI 0.75-0.95). The opulation-attributable fraction of nuclear cataract due to serum 25(OH)D insufficiency (D levels were inversely associated with the risk of nuclear cataract. Prospective studies investigating the effects of serum 25(OH)D levels on the development of nuclear cataract are needed to confirm our findings.

    to evaluate the efficiency of new torsional phacoemulsification software (Ozil IP system) in hard nucleus cataract extraction. 45 eyes with hard senile cataract (degree III and IV) underwent phacoemulsification performed by the same surgeon, using the same technique (stop and chop). Infiniti (Alcon) platform was used, with Ozil IP software and Kelman phaco tip miniflared, 45 degrees. The nucleus was split into two and after that the first half was phacoemulsificated with IP-on (group 1) and the second half with IP-off (group 2). For every group we measured: cumulative dissipated energy (CDE), numbers of tip closure that needed manual desobstruction the amount of BSS used. The mean CDE was the same in group 1 and in group 2 (between 6.2 and 14.9). The incidence of occlusion that needed manual desobstruction was lower in group 1 (5 times) than in group 2 (13 times). Group 2 used more BSS compared to group 1. The new torsional software (IP system) significantly decreased occlusion time and balanced salt solution use over standard torsional software, particularly with denser cataracts.

    Full Text Available Methylphenidate hydrochloride (Ritalin is the drug of choice for attention deficit hyperactivity disorder (ADHD. However, an association of Ritalin with glaucoma has been reported. We report a case of Ritalin-associated cataract and glaucoma. A 10-year-old boy was diagnosed with ADHD and had received methylphenidate hydrochloride, 60 mg/day for 2 years. He presented with blurred vision. Best-corrected visual acuity was 6/60 in both eyes. Ocular examinations revealed intraocular pressure (IOP of 30 mmHg under medication, dense posterior subcapsular opacity of lens, pale disc with advanced cupping, and marked constriction of visual field. Despite maximal anti-glaucomatous medication, IOP still could not be controlled. The patient then received combined cataract and glaucoma surgery. Visual acuity improved and IOP was within normal limits in both eyes postoperatively. Large dose of methylphenidate may cause cataract and glaucoma. The mechanism remains unclear. Doctors should be aware of the possible ocular side effects of methylphenidate.

  16. Principles and paradigms of pediatric cataract management

    Full Text Available Propensity for increased postoperative inflammation and capsular opacification, a refractive state that is constantly in a state of flux due to growth of the eye, difficulty in documenting anatomic and refractive changes due to poor compliance, and a tendency to develop amblyopia, makes management of cataract in the child different from that in the adult. The recent past has unraveled several caveats of pediatric cataract management - the importance of atraumatic surgery and complete removal of lens matter, benefits of in-the-bag intraocular lens(IOL implantation, role of titrating IOL power to counter refractive changes due to growth of the eye, prudery of continuously following these eyes for early detection of aphakic glaucoma and benefits of some surgical innovations. Although these promise to significantly improve our management of pediatric cataract, their long-term benefits are yet to be determined. We will also have to harness newer techniques, especially in the areas of wound construction and capsule management, and will have to develop effective strategies for the refractive management of infantile aphakia.

    Full Text Available Abstract Background Rural Australians are known to experience a higher burden of ischaemic heart disease (IHD than their metropolitan counterparts and the reasons for this appear to be highly complex and not well understood. It is not clear what interventions and prevention efforts have occurred specifically in rural Australia in terms of IHD. A summary of this evidence could have implications for future action and research in improving the health of rural communities. The aim of this study was to review all published interventions conducted in rural Australia that were aimed at the primary and/or secondary prevention of ischaemic heart disease (IHD in adults. Methods Systematic review of the peer-reviewed literature published between January 1990 and December 2015. Search terms were derived from four major topics: (1 rural; (2 ischaemic heart disease; (3 Australia and; (4 intervention/prevention. Terms were adapted for six databases and three independent researchers screened results. Studies were included if the published work described an intervention focussed on the prevention or reduction of IHD or risk factors, specifically in a rural population of Australia, with outcomes specific to participants including, but not limited to, changes in diet, exercise, cholesterol or blood pressure levels. Results Of 791 papers identified in the search, seven studies met the inclusion criteria, and one further study was retrieved from searching reference lists of screened abstracts. Typically, excluded studies focused on cardiovascular diseases without specific reference to IHD, or presented intervention results without stratification by rurality. Larger trials that included metropolitan residents without stratification were excluded due to differences in the specific needs, characteristics and health service access challenges of rural populations. Six interventions were primary prevention studies, one was secondary prevention only and one included both

    Strokes are often preceded by a transient ischaemic attack (TIA) or 'minor' stroke. The immediate period after a TIA/minor stroke is a crucial time to initiate secondary prevention. However, the optimal approach to prevention, including non-pharmacological measures, after TIA is not clear. To systematically review evidence about the effectiveness of delivering secondary prevention, with lifestyle interventions, in comprehensive rehabilitation programmes, initiated within 90 days of a TIA/minor stroke. Also, to categorise the specific behaviour change techniques used. The review identified randomised controlled trials by searching the Cochrane Library, Ovid MEDLINE, Ovid EMBASE, Web of Science, EBSCO CINAHL and Ovid PsycINFO. Two review authors independently screened titles and abstracts for eligibility (programmes initiated within 90 days of event; outcomes reported for TIA/minor stroke) and extracted relevant data from appraised studies; a meta-analysis was used to synthesise the results. A total of 31 potentially eligible papers were identified and four studies, comprising 774 patients post-TIA or minor stroke, met the inclusion criteria; two had poor methodological quality. Individual studies reported increased aerobic capacity but meta-analysis found no significant change in resting and peak systolic blood pressure, resting heart rate, aerobic capacity, falls, or mortality. The main behaviour change techniques were goal setting and instructions about how to perform given behaviours. There is limited evidence of the effectiveness of early post-TIA rehabilitation programmes with preventive lifestyle interventions. Further robust randomised controlled trials of comprehensive rehabilitation programmes that promote secondary prevention and lifestyle modification immediately after a TIA are needed. © British Journal of General Practice 2017.

  19. Measuring aniseikonia using scattering filters to simulate cataract

    2011-12-01

    The relationship between anisometropia and aniseikonia (ANK) is not well understood. Ametropic cataract patients provide a unique opportunity to study this relationship after undergoing emmetropizing lens extraction. Because light scatter may affect ANK measurement in cataract patients, its effect should also be evaluated. The Basic Aniseikonia Test (BAT) was evaluated using afocal size lenses to produce specific changes in retinal height. Several light scattering devices were then evaluated to determine which produced effects most similar to cataract. Contrast sensitivity and visual acuity (VA) losses were measured with each device and compared to those reported in cataract. After determining the most appropriate light scattering device, twenty healthy patients with normal visual function were recruited to perform the BAT using the filters to simulate cataract. Cataract patients were recruited from Vision America and the University of Alabama at Birmingham School of Optometry. Patients between 20 and 75 years of age with at least 20/80 VA in each eye, ≥ 2D ametropia, and normal binocular function were recruited. Stereopsis and ANK were tested and each patient completed a symptom questionnaire. ANK measurements using afocal size lenses indicated that the BAT underestimates ANK, although the effect was minimal for vertical targets and darkened surroundings, as previously reported. Based on VA and contrast sensitivity loss, Vistech scattering filters produced changes most similar to cataract. Results of the BAT using Vistech filters demonstrated that a moderate cataract but not a mild cataract may affect the ANK measurement. ANK measurements on cataract patients indicated that those with ≥ 2 D ametropia in each eye may suffer from induced ANK after the first cataract extraction. With upcoming healthcare reform, unilateral cataract extraction may be covered, but not necessarily bilateral, depending on patient VA in each eye. However, a questionnaire about symptoms

    To report the long-term results of temporary piggyback IOL implantation in congenital cataract and to compare the clinical outcomes of temporary piggyback IOL with those of single IOL implantation. This is a retrospective, comparative, interventional study. The medical records of all consecutive patients who underwent cataract extraction and single or temporary piggyback IOL implantation within the first 3 years of life from 1999 to 2013 at Samsung Medical Center were reviewed. Twenty-eight eyes from 18 patients underwent single IOL implantation (monopseudophakia group), and 32 eyes of 20 patients underwent temporary piggyback IOL implantation in congenital cataract surgery (polypseudophakia group). The mean age at initial cataract surgery was 15.8 months in the monopseudophakia group and 11.1 months in the polypseudophakia group (P = 0.144). The average follow-up duration was 133 months in the monopseudophakia group and 120 months in the polypseudophakia group (P = 0.391). The best-corrected visual acuity at the last visit was 0.36 logMAR in the monopseudophakia group and 0.55 logMAR in the polypseudophakia group (P = 0.044). Four (14%) and 14 (44%) reoperations for complications within the anterior segment were performed in the monopseudophakia group and polypseudophakia group, respectively (P = 0.042). Four cases (14.3%) in the monopseudophakia group and 13 cases (40.6%) in the polypseudophakia group had a glaucoma-related adverse event (P = 0.086). Compared with primary single IOL implantation in congenital cataract, temporary piggyback IOL implantation produced worse visual acuity, higher reoperation rate, and higher risk of secondary glaucoma. Temporary piggyback IOL implantation does not have benefit in congenital cataract.

    Full Text Available Abstract Background The purpose of this research is to develop and evaluate methods for conducting pragmatic cluster randomized trials in a primary care electronic database. The proposal describes one application, in a less frequent chronic condition of public health importance, secondary prevention of stroke. A related protocol in antibiotic prescribing was reported previously. Methods/Design The study aims to implement a cluster randomized trial (CRT using the electronic patient records of the General Practice Research Database (GPRD as a sampling frame and data source. The specific objective of the trial is to evaluate the effectiveness of a computer-delivered intervention at enhancing the delivery of stroke secondary prevention in primary care. GPRD family practices will be allocated to the intervention or usual care. The intervention promotes the use of electronic prompts to support adherence with the recommendations of the UK Intercollegiate Stroke Working Party and NICE guidelines for the secondary prevention of stroke in primary care. Primary outcome measure will be the difference in systolic blood pressure between intervention and control trial arms at 12-month follow-up. Secondary outcomes will be differences in serum cholesterol, prescribing of antihypertensive drugs, statins, and antiplatelet therapy. The intervention will continue for 12 months. Information on the utilization of the decision-support tools will also be analyzed. Discussion The CRT will investigate the effectiveness of using a computer-delivered intervention to reduce the risk of stroke recurrence following a first stroke event. The study will provide methodological guidance on the implementation of CRTs in electronic databases in primary care. Trial registration Current Controlled Trials ISRCTN35701810

A minimum inflammation free period of 3mo (defined as less than 5 cells per high power field in anterior chamber was a pre-requisite for eligibility for surgery. Superior scleral tunnel incisions were used for both techniques. Improvement in visual acuity post-operatively was the primary outcome measure and the rate of post-operative complications and surgical time were secondary outcome measures, respectively. Means of groups were compared using t-tests. One way analysis of variance (ANOVA was used when there were more than two groups. Chi-square tests were used for proportions.

    Glaucoma combined with an extremely shallow anterior chamber and cataracts remains as a complex condition to deal with. And the emergence of microincision vitrectomy surgery (MIVS) system may provide an ideal option for the treatment of that. We report a clinical study of surgical outcomes of 23-gauge transconjunctival pars plana vitrectomy (PPV) combined with lensectomy in the treatment of glaucomatous eyes with extremely shallow anterior chamber and cataract. Prospective, nonrandomized and noncomparative case series study. Consecutive patients with secondary glaucoma, extremely shallow anterior chamber and cataract were recruited to have combined surgeries of 23-gauge transconjunctival pars plana vitrectomy and lensectomy. The main outcomes were best corrected visual acuity (BCVA), intraocular pressure (IOP), anterior chamber depth (ACD), number of anti-glaucoma medications and surgery-associated complications. Seventeen consecutive patients with secondary glaucoma, extremely shallow anterior chamber and cataract were recruited. The mean follow-up was 21.2 ± 8.8 months. Postoperatively, there was no significant improvement of BCVA (P = 0.25). The mean intraocular (IOP) decreased significantly from 43.14 ± 6.53 mmHg to 17.29 ± 1.80 mmHg (P shallow anterior chamber and cataract can be managed well with the combined surgeries of 23-gauge pars plana vitrectomy and lensectomy. The surgical procedure is an effective and safe method to resolve the pupillary block and deepen the anterior chamber.

    A dominant cataract mutation was detected recently among the offspring of x-ray-irradiated male mice. The mutation, which causes total lens opacity, has provisionally been designated by the gene symbol Cat-2t. In the lenses of heterozygous and homozygous Cat-2t mutants, the epithelial and fiber cells were swollen and the lens capsule was ruptured. The histologic analysis demonstrated a complete destruction of the cellular organization of the lens, which might be caused by its altered developmental processes. The data derived from biochemical investigations indicate that biochemistry of the cataractous Cat-2t lenses is affected: the osmotic state as indicated by the increased water content and increased Na(+)-K(+)-adenosinetriphosphatase (ATPase) activity; the energy state as indicated by the decreased adenosine triphosphate (ATP) concentration; and the redox state as indicated by the enhanced content of oxidized glutathione. Additionally, the lenticular protein composition is altered because of the presence of vimentin in the water-soluble fraction. This cannot be explained by the enhanced crosslinking activity of transglutaminase. The changes of the osmotic, energy, and redox states are considered to be secondary in relation to the altered lenticular development. In contrast, the variations concerning vimentin and transglutaminase might be a biochemical indication of the changed development. Possible similarities to other dominantly expressed murine cataract mutants are discussed

    Ankle sprains are the most common sports and physical activity related injury. There is extensive evidence that there is a twofold increased risk for injury recurrence for at least one year post injury. In up to 50% of all cases recurrences result in disability and lead to chronic pain or instability, requiring prolonged medical care. Therefore ankle sprain recurrence prevention in athletes is essential. This RCT evaluates the effect of the combined use of braces and neuromuscular training (e.g. proprioceptive training/sensorimotor training/balance training) against the individual use of either braces or neuromuscular training alone on ankle sprain recurrences, when applied to individual athletes after usual care. This study was designed as three way randomized controlled trial with one year follow-up. Healthy individuals between 12 and 70 years of age, who were actively participating in sports and who had sustained a lateral ankle sprain in the two months prior to inclusion, were eligible for inclusion. After subjects had finished ankle sprain treatment by means of usual care, they were randomised to any of the three study groups. Subjects in group 1 received an eight week neuromuscular training program, subjects in group 2 received a sports brace to be worn during all sports activities for the duration of one year, and group 3 received a combination of the neuromuscular training program and a sports brace to be worn during all sports activities for the duration of eight weeks. Outcomes were assessed at baseline and every month for 12 months therafter. The primary outcome measure was incidence of ankle sprain recurrences. Secondary outcome measures included the direct and indirect costs of recurrent injury, the severity of recurrent injury, and the residual complaints during and after the intervention. The ABrCt is the first randomized controlled trial to directly compare the secondary preventive effect of the combined use of braces and neuromuscular training

    Full Text Available BACKGROUND Cataract is the principal cause of avoidable blindness in India and throughout the world. Surgical removal of the cataractous lens remains the only effective treatment for management of cataract blindness. The success of cataract surgery is determined by best and earliest visual recovery. But the occurrence of postoperative astigmatism has become a major hurdle in achieving this goal. AIMS The study was designed to compare the amount of astigmatism following conventional extracapsular cataract extraction (ECCE and manual small incision cataract surgery (SICS. MATERIALS AND METHODS The study was carried out in 100 eyes of 75 patients aged between 50 and 80 years admitted for cataract surgery. Out of these, 50 eyes were operated by conventional extracapsular cataract extraction and 50 eyes by manual small incision cataract surgery. The patients were followed up at 2 nd , 4 th , 6 th and 8 th weeks. At each follow-up visual acuity, refraction and acceptance and keratometry were recorded and the findings analysed for astigmatism. RESULTS In the current study, the mean (SD astigmatism developed at the end of the 2 nd , 4 th and 6 th of follow-up was significantly lower in the SICS group as compared to the ECCE group (P<0.000. At the end of 8 weeks of follow-up, the mean (SD astigmatism of the SICS group was 0.64±0.56 D as compared to the mean (SD of the ECCE group of 1.39±86 D and the difference was found to be significant (p<0.014. CONCLUSION The current study concludes that manual small incision cataract surgery is a better technique to control postoperative astigmatism than conventional extracapsular cataract extraction.

    Cataract is defined as a lenticular opacity presenting usually with poor visual acuity. It is one of the most common causes of visual impairment worldwide. Early diagnosis demands the expertise of trained healthcare professionals, which may present a barrier to early intervention due to underlying costs. To date, studies reported in the literature utilize a single learning model for retinal image classification in grading cataract severity. We present an ensemble learning based approach as a means to improving diagnostic accuracy. Three independent feature sets, i.e., wavelet-, sketch-, and texture-based features, are extracted from each fundus image. For each feature set, two base learning models, i.e., Support Vector Machine and Back Propagation Neural Network, are built. Then, the ensemble methods, majority voting and stacking, are investigated to combine the multiple base learning models for final fundus image classification. Empirical experiments are conducted for cataract detection (two-class task, i.e., cataract or non-cataractous) and cataract grading (four-class task, i.e., non-cataractous, mild, moderate or severe) tasks. The best performance of the ensemble classifier is 93.2% and 84.5% in terms of the correct classification rates for cataract detection and grading tasks, respectively. The results demonstrate that the ensemble classifier outperforms the single learning model significantly, which also illustrates the effectiveness of the proposed approach.

    This article raises awareness about the cost-effectiveness and carbon footprint of various cataract surgery techniques, comparing their relative carbon emissions and expenses: manual small-incision cataract surgery (MSICS), phacoemulsification, and femtosecond laser-assisted cataract surgery. As the most commonly performed surgical procedure worldwide, cataract surgery contributes significantly to global climate change. The carbon footprint of a single phacoemulsification cataract surgery is estimated to be comparable to that of a typical person's life for 1 week. Phacoemulsification has been estimated to be between 1.4 and 4.7 times more expensive than MSICS; however, given the lower degree of postoperative astigmatism and other potential complications, phacoemulsification may still be preferable to MSICS in relatively resource-rich settings requiring high levels of visual function. Limited data are currently available regarding the environmental and financial impact of femtosecond laser-assisted cataract surgery; however, in its current form, it appears to be the least cost-effective option. Cataract surgery has a high value to patients. The relative environmental impact and cost of different types of cataract surgery should be considered as this treatment becomes even more broadly available globally and as new technologies are developed and implemented.

    Full Text Available Examination of natural ageing processes including those caused by multiple external factors has been attracting re-searchers' attention over the last years. Senile cataract is a multi-factor disease. Expenditure on cataract surgery remain one of the greatest expenses items in public health care. Age is a basic factor which causes senile cataract. Morbidity with cataract doubles each 10 years of life. This outline considers some literature sources which describe research results on influence exerted on cataract evolvement by such risk factors as age, sex, race, smoking, alcohol intake, pancreatic diabetes, intake of certain medications, a number of environmental factors including ultraviolet and ionizing radiation. mane of these factors are shown to increase or reduce senile cataract risk; there are conflicting data on certain factors. The outline also contains quantitative characteristics of cataract risks which are given via odds relation and evolve due to age parameters impacts, alcohol intake, ionizing radiation, etc. The authors also state that still there is no answer to the question whether dose-effect relationship for cataract evolvement is a threshold or non-threshold.

Animals were divided into groups and treated once daily with oral ranirestat (0.1, 1.0, 10 mg/kg or epalrestat (100 mg/kg for 40 weeks, normal Sprague-Dawley rats, and untreated SDT rats. Lens opacification was scored from 0 (normal to 3 (mature cataract. The combined scores (0–6 from both lenses represented the total for each animal. DN was assessed by measuring the motor nerve conduction velocity (MNCV in the sciatic nerve. Sorbitol and fructose levels were measured in the lens and sciatic nerve 40 weeks after diabetes onset. Cataracts developed more in untreated rats than normal rats (P<0.01. Ranirestat significantly (P<0.01 inhibited rapid cataract development; epalrestat did not. Ranirestat significantly reversed the MNCV decrease (40.7 ± 0.6 m/s in SDT rats dose-dependently (P<0.01. Epalrestat also reversed the prevented MNCV decrease (P<0.05.

    We investigated whether heat-shock transcription factor 1 (HSF1) was involved in ultraviolet radiation type B (UVR-B)-induced lens opacity (cataract) using HSF1 heterozygous mice. We also examined the effects of geranylgeranylacetone (GGA), an inducer of heat-shock proteins via activation of HSF, on the UVR-B-induced cataract. Male HSF1 +/- and WT mice were unilaterally exposed to UVR-B (total: 1200mJ) at 16 weeks of age. At 48 h after the last UVR-B irradiation, the lens was isolated and the induction of the cataract was quantified as the cataract area ratio (opacity area/anterior capsule). GGA was orally administered at a dosage of 500 mg/kg once a day for two days before the first UVR-B exposure until the end of the experiment (21days in total). The HSF1 expression was more greatly decreased in the lens from HSF1 +/- mice than in that from WT mice (p B exposure could mainly induce cataracts in the anterior capsule in both HSF1 +/- and WT mice, while the opacity of the lens was markedly enhanced in HSF 1+/- mice compared to that in WT mice(p (0.01). GGA treatment could prevent the induction of lens opacity by UVR-B exposure in both WT and HSF1 +/- mice as compared with the non-administration group (p B radiation was seen in lens protein levels of αA-crystallin, αB-crystallin, or γ-crystallin with or without GGA administration among all groups of mice. In contrast to the crystallins, the lens protein level of HSP25 was decreased by UVR-B exposure in both HSF1 +/- and WT mice, and was significantly recovered in WT mice by the GGA treatment (p B-induced cataracts, possibly via regulation of HSPs such as HSP25.

    Describe an unusual case of bilateral pigment dispersion syndrome (PDS) following years of uninterrupted treatment with atropine 1% for bilateral congenital cataracts, speculate on potential mechanisms leading to this condition. This is a case report. A 45-year-old white patient on long-term treatment with atropine 1% ointment since his infancy for bilateral congenital cataracts developed PDS with secondary ocular hypertension. The patient showed all the hallmarks of PDS with secondary ocular hypertension. An anterior segment Swept-Source optical coherence tomography was obtained to review the iris profile. The patient showed good pressure response to topical prostaglandin therapy. This is the second case report of PDS in a patient with chronic use of topical atropine. The proposed mechanisms for pigment dispersion are discussed and the possibility raised of dispersion being a potential side effect of the drug.

    In most Asian countries, stroke is one of the major causes of mortality. A stroke event is life-changing for stroke survivors, which results in either mortality or disability. Therefore, this study comprehensively focuses on prevalence, risk factors, and secondary prevention for stroke recurrence identified in South, East, and Southeast Asian countries. This scoping review uses the methodological framework of Arksey and O'Malley. A comprehensive search of academic journals (English) on this topic published from 2007 to 2017 was conducted. A total of 22 studies were selected from 585 studies screened from the electronic databases. First-year stroke recurrence rates are in the range of 2.2% to 25.4%. Besides that, modifiable risk factors are significantly associated with pathophysiological factors (hypertension, ankle-brachial pressure index, atherogenic dyslipidaemia, diabetes mellitus, metabolic syndrome, and atrial fibrillation) and lifestyle factors (obesity, smoking, physical inactivity, and high salt intake). Furthermore, age, previous history of cerebrovascular events, and stroke subtype are also significant influence risk factors for recurrence. A strategic secondary prevention method for recurrent stroke is health education along with managing risk factors through a combination of appropriate lifestyle intervention and pharmacological therapy. To prevent recurrent stroke, health intervention should be geared towards changing lifestyle to embody a healthier approach to life. This is of great importance to public health and stroke survivors' quality of life.

    Full Text Available Aim. To study secondary prevention of cardiovascular diseases among patients of different age groups with a history of myocardial infarction by the example of outpatient cardiology institution.Material and methods. Retrospective pharmacoepidemiological study was conducted by analyzing the medical records of 825 patients with a history of myocardial infarction, who visited the outpatient cardiology institution for the first time in 2011. Patients were divided into two groups according to their age: younger than 60 years (n=308, and 60 years and older (n=517.Results. The population of elderly patients was more severe: significantly more often patients had disability and comorbidities. The prevalence of the main modifiable risk factors could not be assessed fully due to the lack of information in patients’ medical records. Elderly patients were significantly less likely to receive β-blockers (80.3% and statins (63.8%. No significant differences were found in daily doses of the main prescribed preventive drugs between two groups.Conclusion. Secondary prevention of cardiovascular diseases among patients of different age groups could not be considered proper, as there is low level of attention to the modifiable risk factors and recommendation on their correction. A tendency to under-prescription of angiotensin converting enzyme inhibitors was revealed, as well as significantly lower number of recommendations for taking statins and β-adrenoblockers in the group of elderly patients.

    Full Text Available Purpose: To develop an uniform method of the treatment for patients with progressive keratoconus (stage 1‑2 and cataract. Patients and methods: 4 patients (5 eyes with cataract and progressive keratoconus stage 1‑2 were enrolled in the study. Mean age was 42 years. In all patients, standard ophthalmic examination as well corneal topography, anterior segment optical coherence tomography, biometry, and IOL power calculations using IOLMaster were performed. Mean uncorrected visual acuity (UCVA was 0.1 while mean best-corrected visual acuity (BCVA was 0.4. Surgical technique included two steps. The first step was the creation of corneal tunnels with femtosecond laser with subsequent phaco and monofocal aspheric IOL implantation. The second step (1‑2 weeks later was the implantation of intrastromal ring segments based on corneal topography and corneal crosslinking.Results: After the first step, all patients had myopic refraction (from –1.0 D to –2.5 D. Cylindrical component was almost unchanged. After the second step, the patients reported the vision improvement, mainly due to UCVA. Both spherical (myopic and cylindrical components decreased, mainly due to the steep meridian. After the treatment, optical power of the cornea decreased, mainly due to the steep meridian. UCVA was 0.6 or more in 60 % of cases, final BCVA was 0.8‑1.0 in 80 % of cases. Neither intraoperative nor postoperative (follow-up was 2 years complications were observed.Conclusions: Combined phaco and prior creation of corneal tunnels with subsequent intrastromal ring segment implantation and crosslinking in patients with cataract and progressive keratoconus stage 1‑2 is safe, provides good predictable outcome and significantly reduces rehabilitation period.

    We discuss some theoretical approaches, experimental results and field data concerning wave phenomena in ocean near-bottom stratified flows. Such strong flows of cold water form everywhere in the Atlantic abyssal channels, and these currents play significant role in the global water exchange. Most interesting wave structures arise in a powerful cataract flows near orographic obstacles which disturb gravity currents by forced lee waves, attached hydraulic jumps, mixing layers etc. All these effects were observed by the authors in the Romanche and Chain fracture zones of Atlantic Ocean during recent cruises of the R/V Akademik Ioffe and R/V Akademik Sergei Vavilov (Morozov et al., Dokl. Earth Sci., 2012, 446(2)). In a general way, deep-water cataract flows down the slope are similar to the stratified flows examined in laboratory experiments. Strong mixing in the sill region leads to the splitting of the gravity current into the layers having the fluids with different densities. Another peculiarity is the presence of critical layers in shear flows sustained over the sill. In the case under consideration, this critical level separates the flow of near-bottom cold water from opposite overflow. In accordance with known theoretical models and laboratory measurements, the critical layer can absorb and reflect internal waves generated by the topography, so the upward propagation of these perturbations is blocked from above. High velocity gradients were registered downstream in the vicinity of cataract and it indicates the existence of developed wave structures beyond the sill formed by intense internal waves.

The patients were divided into three groups based on postoperative diopter: -1.0~-2.0D(group A, -2.25~-3.0D(group Band -3.25~-4.0D(group C. The uncorrected distance visual acuity(UCDVA, best corrected distant visual acuity(BCDVA, uncorrected near visual acuity(UCNVAand questionnaire of Activities of Daily Vision Scale(ADVSwere collected to assess the vision gain at 3mo after cataract surgery. RESULTS: At 3mo after surgery, UCDVA of group A was better than that of group B, and UCDVA of group B was better than that of group C. There were no differences in BCDVA among groups. There were significant differences between the three groups' UCNVA, it was best for the group C, followed by the group B, group A was the worst. For questionnaire, no difference was observed in patients' satisfactory for surgical results, but a significant difference was detected in postoperative glasses wearing frequency between groups. CONCLUSION:For cataract surgery in high myopia combined cataract, postoperative diopter should be calculated based on patients' daily requirements. For patients had not used to wearing glasses and near distant working condition, it's appropriated to reserve a minor degree of myopia. Conversely, for patients require near distant working and received wearing moderate and low hyperopia mirror, higher degree of myopia can be reserved.

    To present an economic-analysis comparison of simultaneous and sequential bilateral cataract surgery. Helsinki University Eye Hospital, Helsinki, Finland. Economic analysis. Effects were estimated from data in a study in which patients were randomized to have bilateral cataract surgery on the same day (study group) or sequentially (control group). The main clinical outcomes were corrected distance visual acuity, refraction, complications, Visual Function Index-7 (VF-7) scores, and patient-rated satisfaction with vision. Health-care costs of surgeries and preoperative and postoperative visits were estimated, including the cost of staff, equipment, material, floor space, overhead, and complications. The data were obtained from staff measurements, questionnaires, internal hospital records, and accountancy. Non-health-care costs of travel, home care, and time were estimated based on questionnaires from a random subset of patients. The main economic outcome measures were cost per VF-7 score unit change and cost per patient in simultaneous versus sequential surgery. The study comprised 520 patients (241 patients included non-health-care and time cost analyses). Surgical outcomes and patient satisfaction were similar in both groups. Simultaneous cataract surgery saved 449 Euros (€) per patient in health-care costs and €739 when travel and paid home-care costs were included. The savings added up to €849 per patient when the cost of lost working time was included. Compared with sequential bilateral cataract surgery, simultaneous bilateral cataract surgery provided comparable clinical outcomes with substantial savings in health-care and non-health-care-related costs.

Conclusion: We found no increased risk of developing cataract among Danish metal welders who worked with arc welding from 1950–1985. This may be attributed to the effectiveness of personal safety equipment....... increases the risk of cataract. Method: We compared the risk of being diagnosed with cataract from 1987–2012 in a historic cohort of 4288 male metal arc welders against a reference group comprised of Danish skilled and unskilled male workers with similar age distribution. For the welders’ cohort...... adjusted for baseline data regarding age, diabetes, and social group. Results: There were 266 welders and 29 007 referents with a diagnosis and/or operation for cataract.

    Full Text Available Perfect vision and fewer complications is our goal in cataract surgery, femtosecond laser-assisted cataract surgery hold the promise. Applications of femtosecond laser technology for capsulotomy, nuclear fragmentation and corneal incision in cataract surgery bring a new level of accuracy, reproducibility and predictability over the current cataract surgery. The femtosecond laser produces capsulotomies that are more precise, accurate, reproducible, and stronger than those created with the conventional manual technique, and further helps maintain proper positioning of the IOL. Femtosecond laser in nuclear fragmentation lead to a lower effective phacoemulsification time, and the corneal incision is more stable. But currently there are some complications and a clear learning curve associated with the use of femtosecond lasers for cataract surgery. The long-term safety and visual outcomes still need further investigation.

    To discuss the increasing utilization of cataract extraction in the management of glaucoma and to highlight advances in surgical care that can promote synergistic treatment of these comorbid conditions. Recent years have demonstrated significant advances in the management of glaucoma through the use of novel microinvasive glaucoma devices. Furthermore, an increased understanding of the role of cataract surgery in the treatment of various glaucomas warrants review. Nevertheless, cataract surgery in the glaucoma patient warrants specific preoperative, intraoperative, and postoperative planning to optimize visual function and quality of life while mitigating potential risk factors for adverse events. Although the challenges of performing cataract extraction on glaucoma patients exist, the potential benefit to these patients is substantial. With attention to pre- and perioperative surgical planning and intraoperative technique, as well as with awareness and potential utilization of novel devices and treatment strategies, cataract extraction offers a unique platform for anatomical and functional improvement in this increasingly common cohort of patients.

    From a theoretical and practical point of view, it is worthwhile to utilize the full potential of prevention of child abuse. However, prevention strategies in the field of child abuse were generally limited to prevention by means of interpersonal communications. This paper seeks to address this lacuna. A case-study is presented by describing and analyzing the organization and program development of a Dutch mass-media intervention aimed at the enhancement of disclosure of abuse of 8- to 15-year-old children, including physical, sexual, and emotional abuse. In the developmental process, several shortcomings are noticed, with respect to problem analysis, goal setting, and the assessment of unplanned effects. Critical comments are made on the intervention density, and the input and output of financial and human resources. Contrary to most preventive interventions, the described intervention could interrupt between the dependency of the abused child on the perpetrator and communicate with children directly. In a field which is in need of more effective prevention strategies, the program described may serve as an example of an ecological approach, which goes beyond the micro system, extending our potential in preventing ongoing abuse.

    Current guidelines recommend that adults with atherosclerotic cardiovascular disease take low-dose aspirin or other antiplatelet medications as secondary prevention of recurrent cardiovascular events. Yet, no national level assessment of low-dose aspirin use for secondary prevention of cardiovascular disease has been reported among a community-based population. Using data from the 2012 National Health Interview Survey, we assessed low-dose aspirin use among those with atherosclerotic cardiovascular disease. We estimated the prevalence ratios of low-dose aspirin use, adjusting for sociodemographic status, health insurance, and cardiovascular risk factors. Among those with atherosclerotic cardiovascular disease (n=3,068), 76% had been instructed to take aspirin, and 88% of those were following this advice. Of those not advised, 11% took aspirin on this own. Overall, 70% were taking aspirin (including those who followed their health care provider's advice and those who were not advised but took aspirin on their own). Logistic regression models showed that women, non-Hispanic blacks and Hispanics, those aged 40–64 years, with a high school education or with some college, or with fewer cardiovascular disease risk factors were less likely to take aspirin than men, non-Hispanic whites, those aged ≥65 years, with a college education or higher, or with all four selected cardiovascular disease risk factors, respectively. Additional analyses conducted among those with coronary heart disease only (n=2,007) showed similar patterns. In conclusion, use of low-dose aspirin for secondary prevention was 70%, with high reported adherence to health care providers' advice to take low-dose aspirin (88%), and significant variability within subgroups.

    The aim of our study was to determine the risk factors for electrical storm (ES) and to assess the impact of ES on the long-term prognosis in patients after myocardial infarction (MI) with an implantable cardioverter-defibrillator (ICD) for secondary prevention of sudden cardiac death (SCD). We retrospectively analyzed 416 patients with coronary artery disease after MI who had an implanted ICD for secondary prevention of SCD. Fifty (12%) patients had one or more incidents of an electrical storm - the ES (+) group. We matched the reference group of 47 patients from 366 ES (-) patients. We analyzed 3,408 episodes of ventricular arrhythmias: 3,148 ventricular tachyarrhythmic episodes in the ES (+) group (including 187 episodes of ES) and 260 in the ES (-) group. Multivariate logistic regression showed that inferior wall MI (RR = 3.98, 95% CI: 1.52-10.41) and the absence of coronary revascularization (RR = 2.92, 95% CI: 1.18-7.21) were independent predictors of ES ( p = 0.0014). During 6-year observation of 97 patients, there were 39 (40%) deaths: 25 (50%) subjects in the ES (+) group and 14 (30%) in the ES (-) group ( p = 0.036). Independent predictors of death were: the occurrence of ES (HR = 1.93), older age (HR = 1.06), and lower left ventricular ejection fraction (HR = 0.95) (for all p storm in patients after MI with ICD for secondary prevention is a relatively common phenomenon and has a negative prognostic significance. Myocardial infarction of the inferior wall and the absence of coronary revascularization are predisposing factors for the occurrence of an ES.

    To evaluate the multinational medical-student-delivered tobacco prevention programme for secondary schools for its effectiveness to reduce the smoking prevalence among adolescents aged 11-15 years in Germany at half year follow-up. We used a prospective quasi-experimental study design with measurements at baseline (t1) and 6 months postintervention (t2) to investigate an intervention in 8 German secondary schools. The participants were split into intervention and control classes in the same schools and grades. A total of 1474 eligible participants of both genders at the age of 11-15 years were involved within the survey for baseline assessment of which 1200 completed the questionnaire at 6-month follow-up (=longitudinal sample). The schools participated voluntarily. The inclusion criteria were age (10-15 years), grade (6-8) and school type (regular secondary schools). Two 60 min school-based modules delivered by medical students. The primary end point was the difference from t1 to t2 of the smoking prevalence in the control group versus the difference from t1 to t2 in the intervention group (difference of differences approach). The percentage of former smokers and new smokers in the two groups were studied as secondary outcome measures. In the control group, the percentage of students who claimed to be smokers doubled from 4.2% (t1) to 8.1% (t2), whereas it remained almost the same in the intervention group (7.1% (t1) to 7.4% (t2); p=0.01). The likelihood of quitting smoking was almost six times higher in the intervention group (total of 67 smokers at t1; 27 (4.6%) and 7 (1.1%) in the control group; OR 5.63; 95% CI 2.01 to 15.79; p<0.01). However, no primary preventive effect was found. We report a significant secondary preventive (smoking cessation) effect at 6-month follow-up. Long-term evaluation is planned.

    To determine if endophthalmitis following cataract surgery is linked to increased mortality. Increased mortality has been linked to patients with cataract and cataract surgery. We tested the hypothesis that post-cataract endophthalmitis has a greater risk of death than pseudophakes who do not develop this complication. Case-control study conducted in a tertiary public hospital. The study group comprised 50 consecutive patients with post-cataract endophthalmitis, and these were matched with selected controls. Patients with endophthalmitis following cataract surgery were identified from a prospective electronic surgical database. Subsequently, it was determined if the patient was deceased at the time of sequestration (September 2015), and the date of death was recorded. A previously described population who had undergone cataract surgery in the same facility was selected as a control group, and the population was case-matched in terms age, gender, presence or absence of diabetes and/or hypertension. The median survival rates were determined for the control group and the patients with post-cataract endophthalmitis. Fifty patients were identified as undergoing endophthalmitis post-cataract surgery, and 48 (n = 48) met inclusion criteria (mean age 72 years ±12 SD with 30:18 F:M); 17% were diabetic, and 50% had systemic hypertension. No statistically significant difference in median survival between the study and control cases was identified (100 months (95% confidence interval 86-114) vs. 106 months (95% confidence interval 66-146), respectively, P = 0.756). Post-cataract endophthalmitis was not associated with an increased rate of mortality in this study. © 2018 Royal Australian and New Zealand College of Ophthalmologists.

    To evaluate the outcome of intraocular lens (IOL) implantation using capsular tension ring (CTR) in subluxated crystalline or cataractous lenses in children. Tertiary care setting. We prospectively studied 18 eyes of 15 children with subluxation of crystalline or cataractous lenses between 90 degrees up to 210 degrees after phacoemulsification, CTR and IOL implantation. Each child was examined for IOL centration, zonular dehiscence and posterior capsular opacification (PCO). Age of the patient ranged between five to 15 years. Out of 18 eyes, seven had traumatic and 11 had spontaneous subluxation of crystalline or cataractous lens. Phacoemulsification was successfully performed with CTR implantation in the capsular bag. Intraoperative zonular dialysis occurred in two eyes. Anterior vitrectomy was performed in six eyes to manage vitreous prolapse. IOL implanted was polymethyl methacrylate (PMMA) in eight eyes, hydrophobic acrylic in seven and hydrophilic acrylic in three. Follow-up ranged from 24 months to 72 months. Sixteen eyes had a best corrected visual acuity of 20/40 or better. Nine eyes developed significant PCO and were managed with Neodymium Yttrium Aluminum Garnet (Nd:YAG) laser posterior capsulotomy. One eye with acrylic IOL in the capsular bag had IOL dislocation after two years which was managed with vitrectomy and secondary trans-scleral fixation of IOL. Phacoaspiration with CTR implantation makes capsular bag IOL fixation possible in most of the eyes with subluxated crystalline or cataractous lenses. PCO still remains a challenge in children with successful phacoaspiration with CTR implantation.

    BACKGROUND: Developing complex interventions for testing in randomised controlled trials is of increasing importance in healthcare planning. There is a need for careful design of interventions for secondary prevention of coronary heart disease (CHD). It has been suggested that integrating qualitative research in the development of a complex intervention may contribute to optimising its design but there is limited evidence of this in practice. This study aims to examine the contribution of qualitative research in developing a complex intervention to improve the provision and uptake of secondary prevention of CHD within primary care in two different healthcare systems. METHODS: In four general practices, one rural and one urban, in Northern Ireland and the Republic of Ireland, patients with CHD were purposively selected. Four focus groups with patients (N = 23) and four with staff (N = 29) informed the development of the intervention by exploring how it could be tailored and integrated with current secondary prevention activities for CHD in the two healthcare settings. Following an exploratory trial the acceptability and feasibility of the intervention were discussed in four focus groups (17 patients) and 10 interviews (staff). The data were analysed using thematic analysis. RESULTS: Integrating qualitative research into the development of the intervention provided depth of information about the varying impact, between the two healthcare systems, of different funding and administrative arrangements, on their provision of secondary prevention and identified similar barriers of time constraints, training needs and poor patient motivation. The findings also highlighted the importance to patients of stress management, the need for which had been underestimated by the researchers. The qualitative evaluation provided depth of detail not found in evaluation questionnaires. It highlighted how the intervention needed to be more practical by minimising administration

    Most smokers start smoking during their early adolescence, often with the idea that smoking is glamorous; the dramatic health consequences are too far in the future to fathom. We recently designed and tested an intervention that takes advantage of the broad availability of mobile phones as well as adolescents' interest in their appearance. A free photoageing mobile app (Smokerface) was implemented by medical students in secondary schools via a novel method called mirroring. The pupils' altered three-dimensional selfies on tablets were 'mirrored' via a projector in front of their whole grade. This is the first randomised trial to measure the effectiveness of the mirroring approach on smoking behaviour in secondary schools. The mirroring intervention, which lasts 45 min, is implemented by Brazilian medical students in at least 35 secondary school classes with 21 participants each (at least 35 classes with 21 participants for control) in February 2018 in the city of Itauna, Brazil. External block randomisation via computer is performed on the class level with a 1:1 allocation. In addition to sociodemographic data, smoking behaviour is measured via a paper-pencil questionnaire before, 3 and 6 months postintervention plus a random carbon monoxide breathing test at baseline and end line. The primary outcome is cigarette smoking in the past week at 6 months follow-up. Smoking behaviour (smoking onset, quitting) and effects on the different genders are studied as secondary outcomes. Analysis is by intention to treat. Ethical approval is obtained from the ethics committee of the University of Itauna in Brazil. Results will be disseminated at conferences, in peer-reviewed journals, throughout the Education Against Tobacco network social media channels and on our websites.

Results: Aqueous humor levels of SIRT1 showed a positive correlation with visual acuity (logarithm of the minimum angle of resolution and with the severity of nuclear cataract (r=0.32 and 0.30, respectively, P<0.05. However, only visual acuity was correlated with SIRT1 according to the stepwise multiple regression analysis (P<0.05. Conclusion: These findings suggest that SIRT1 may have an effect on the formation of ARC, acting as a defensive factor against ARC.

    Full Text Available Introduction: Dry eye is a common problem amongst post-menopausal women. Cataract surgery may worsen symptoms of dry eye and this can inflence the quality of life in patients. Ths study was performed to evaluate the incidence and severity of dry eye symptoms aftr phacoemulsifiation surgery. Methods: Ths case-series study was performed on 43 women aged over 50 years during 2013-2014. Patients underwent phacoemulsifiation surgery on one eye. Symptoms of the operated and contra lateral eye were analyzed by χ2 statistical test and SPSS softare, preoperative and one month aftr the surgery. Results: One month aftr the surgery, the mean value of incidence and severity of dry eye in operated and non-operated eyes were 90.06 ± 3.5, 80.96 ± 3.55, 71.11 ± 3.52, and 63.51 ± 3.04, respectively. Th diffrence between the two groups was signifiant (P > 0.001. Schirmer’s test, TBUT and corneal staining showed no signifiant diffrence (P ≥ 0.05. conclusions: Cataract surgery may lead to worsening of dry eye symptoms. Treatment of dry eye before cataract surgery is an important issue to prevent ocular surface damage.

    Purpose The aim of this study was to evaluate the safety, tolerability, and efficacy of a low-dose version of bromfenac 0.075% in DuraSite® (bromfenac 0.075%) compared with DuraSite® vehicle (vehicle) alone for the treatment of postoperative inflammation and ocular pain after cataract surgery. Methods A multicenter, double-masked, vehicle-controlled, parallel-group clinical trial of 240 subjects randomized in a 2:1 ratio to bromfenac 0.075% or vehicle was conducted. Subjects were dosed BID beginning 1 day before the cataract surgery, the day of surgery, and 14 days after surgery. A slit lamp biomicroscopy examination was performed to evaluate the signs of inflammation, including anterior chamber cells (ACC) and anterior chamber flare (ACF). The primary efficacy variable was the proportion of subjects with an ACC grade of 0 at Day 15. Secondary efficacy endpoints included the proportion of subjects who achieved a pain score of 0 at each postsurgical visual analog scale (VAS) assessment and the proportion of subjects with an ACF grade of 0 at Day 15. Results At Day 15, proportionally more subjects in the bromfenac 0.075% group than in the vehicle group had an ACC grade of 0 (57.1% vs 18.8%, respectively; P<0.001). At each of the postsurgical time points (Days 1, 8, 15, and 29), proportionally more bromfenac 0.075%-treated subjects (76.8%, 90.5%, 92.9%, and 85.1%, respectively) had no pain (a VAS score of 0) compared with the vehicle-treated subjects (48.2%, 38.8%, 42.4%, and 47.1%, respectively), and at each time point, these differences in proportions were statistically significant (P<0.001). More subjects in the bromfenac 0.075% group had complete ACF resolution (151/167; 90.4%) compared to those in the vehicle group (54/85; 63.5%). There were no new safety signals reported. Conclusion Bromfenac 0.075% in DuraSite is safe, well tolerated, and effective at reducing inflammation and preventing pain associated with cataract surgery. PMID:27920490

    Full Text Available To present a rare complication, such as bilateral cataracts, in a man who sustained a high-voltage electrical injury. A 35- year-old man was admitted with a complaint of decrease in visual acuity. He had a history of a contact with a power line carrying 30.000 volts of electricity while working at a construction site. Examination at a burn center revealed second-degree facial, neck and left foot burns. One month later, the patient underwent amputation of fourth and fifth toes of his left foot. During the next 6 months, he noted decreasing vision in both eyes. Ocular examination 1 year after the accident revealed that the patient’s visual acuity had deteriorated to 1/10 in both eyes. The cornea on the left eye showed superficial punctate opacities. The lenses in both eyes had anterior subcapsular cortical lens opacities and posterior subcapsular opacities. Uncomplicated bilateral phacoemulsification surgery with intraocular lens implantation was performed and the patient’s visual acuity returned to 10/10 in both eyes. We noted that the fundus remained normal in both eyes. Electrical cataracts are still a serious potential complication that may occur after electrical injury. Awareness of this by burn team members is important for providing optimal treatment to those who have suffered an electrical injury. (Turk J Ophthalmol 2011; 41: 197-9

  16. Human lens colouration, age and cataract

    Full text: The human lens biosynthesises UV filter compounds which effectively remove light in the 300-400nm band. These chemicals are present either as an aid to visual acuity, or to filter out damaging UV radiation. The primate UV filters are 3-hydroxykynurenine analogues derived from the metabolism of tryptophan. We have recently demonstrated that these endogenous UV filters are not innocuous, but are in fact capable of binding to proteins, including the crystalline proteins which make up the bulk of the lens. Thus, over time, the levels of protein - bound UV filters increase and this results in the human lens becoming progressively more yellow as we age. This colouration affects our colour vision and it may also be responsible for the brown colour of lenses which is the hallmark of age-related nuclear cataract. An understanding of the intrinsic instability of the endogenous UV filters, combined with changes in the internal transport of these and other small molecular weight compounds including antioxidants, such as glutathione, is allowing us to gain an insight into the processes responsible for the development of age-related cataract: the major cause of world blindness

    This review is timely because the outcomes of surgical invention in uveitic eyes with cataract can be optimized with adherence to strict anti-inflammatory principles. All eyes should be free of any cell/ flare for a minimum of 3 months preoperatively. Another helpful maneuver is to place dexamethasone in the infusion fluid or triamcinolone intracamerally at the end of surgery. Recent reports about the choice of intraocular lens material or lens design are germane to the best surgical outcome. Integrating these findings will promote better visual outcomes and allow advancement in research to further refine these surgical interventions in high-risk uveitic eyes. Control of inflammation has been shown to greatly improve postoperative outcomes in patients with uveitis. Despite better outcomes, more scientific research needs to be done regarding lens placement and materials and further research needs to adhere to the standardized reporting of uveitis nomenclature. Future studies should improve postoperative outcomes in eyes with uveitis so that they approach those of eyes undergoing routine cataract procedures.

    Full Text Available Purpose: We report a case of pigment dispersion glaucoma secondary to uncomplicated phakic intraocular collamer lens (ICL (Visian ICL™, Staar Inc., Monrovia, CA implant that resulted in advanced visual field loss. Observations: A 50-year-old man presented for routine follow-up status post bilateral phakic intraocular collamer lens (ICL placement 8 years earlier. He was incidentally found to have a decline in visual acuity from an anterior subcapsular cataract and elevated intraocular pressure (IOP in the left eye. There were signs of pigment dispersion and no evidence of angle closure. Diffuse optic nerve thinning was consistent with advanced glaucomatous visual field defects. Pigment dispersion was also present in the patient's right eye, but without elevated IOP or visual field defects. The patient was treated with topical glaucoma medications and the phakic ICL in the left eye was removed concurrently with cataract surgery to prevent further visual field loss. Conclusions and importance: Pigment dispersion glaucoma is a serious adverse outcome after phakic ICL implantation and regular post-operative monitoring may prevent advanced visual field loss.

    Full Text Available AIM:To investigate the safety and efficacy of capsular tension ring(CTRinsertion combined with phacoemulsification and intraocular lens(IOLimplantation in patient with pseudoexfoliation syndrome after anti-glaucoma surgery.METHODS: A retrospective study was conducted of 10 eyes from 10 cataract patients with pseudoexfoliation syndrome following trabeculectomy surgery, and who underwent CTR insertion combined with phacoemulsification and IOL implantation between January, 2012 and June, 2013. All cases had nuclear cataracts(nuclear hardness Ⅱ 1 eye, nuclear hardness Ⅲ 4 eyes, nuclear hardness Ⅳ 5 eyes. One case with Ⅳ nuclear hardness cataract had iridodonesis and lens subluxation. Postoperative visual acuity, intra- and post-operative complications, anterior capsular opening, IOL position, and postoperative intraocular pressure(IOPwere assessed. Follow-ups ranged from 3 to 14mo. The t test was used to analyze the variables studied.RESULTS: All patients had a successful CTR insertion combined with phacoemulsification and IOL implantation. A modified CTR insertion was performed in one case, the others underwent a standard CTR insertion. The best corrected visual acuity(BCVAwas ≥0.5 in 3 eyes and 0.3-t=1.9955, P>0.05. The most common intrao- and post-operative complications were corneal edema, small pupil, residual cortex, spontaneous zonular dialysis.CONCLUSION: Suitable CTR insertion in appropriate occasion may be beneficial to patients with pseudoexfoliation syndrome after trabeculectomy during cataract surgery. It prevents the IOL decentration and decrease the surgical complication. Less complication occurs at the early stage.

    Men generally have higher rates of suicide, despite fewer overt indicators of risk. Differences in presentation and response suggest a need to better understand why suicide prevention is less effective for men. To explore the views of at-risk men, friends and family about the tensions inherent in suicide prevention and to consider how prevention may be improved. Secondary analysis of qualitative interview and focus group data, using thematic analysis techniques, alongside bracketing, construction and contextualisation. A total of 35 men who had recently made a suicide attempt participated in interviews, and 47 family and friends of men who had made a suicide attempt took part in focus groups. Participants recounted their experiences with men's suicide attempts and associated interventions, and suggested ways in which suicide prevention may be improved. Five tensions in perspectives emerged between men and their support networks, which complicated effective management of suicide risk: (i) respecting privacy vs monitoring risk, (ii) differentiating normal vs risky behaviour changes, (iii) familiarity vs anonymity in personal information disclosure, (iv) maintaining autonomy vs imposing constraints to limit risk, and (v) perceived need for vs failures of external support services. Tension between the different perspectives increased systemic stress, compounding problems and risk, thereby decreasing the effectiveness of detection of and interventions for men at risk of suicide. Suggested solutions included improving risk communication, reducing reliance on single source supports and increasing intervention flexibility in response to individual needs. © 2017 The Authors Health Expectations Published by John Wiley & Sons Ltd.

    To identify predictive factors associated with the development of pressure ulcers in patients at risk who receive standardized preventive care. Numerous studies have examined factors that predict risk for pressure ulcer development. Only a few studies identified risk factors associated with pressure ulcer development in hospitalized patients receiving standardized preventive care. Secondary analyses of data collected in a multicentre randomized controlled trial. The sample consisted of 610 consecutive patients at risk for pressure ulcer development (Braden Score Pressure ulcers in category II-IV were significantly associated with non-blanchable erythema, urogenital disorders and higher body temperature. Predictive factors significantly associated with superficial pressure ulcers were admission to an internal medicine ward, incontinence-associated dermatitis, non-blanchable erythema and a lower Braden score. Superficial sacral pressure ulcers were significantly associated with incontinence-associated dermatitis. Despite the standardized preventive measures they received, hospitalized patients with non-blanchable erythema, urogenital disorders and a higher body temperature were at increased risk for developing pressure ulcers. Improved identification of at-risk patients can be achieved by taking into account specific predictive factors. Even if preventive measures are in place, continuous assessment and tailoring of interventions is necessary in all patients at risk. Daily skin observation can be used to continuously monitor the effectiveness of the intervention. © 2014 John Wiley & Sons Ltd.
