RESUMEN
BACKGROUND: Myopia is becoming increasingly prevalent throughout the world. It is an overlooked but leading cause of blindness, particularly among the working aged population. Myopia is often considered benign because it is easily corrected with glasses, contact lenses or refractive surgery. Traditionally myopia has been classified into physiological and pathological subtypes based on the degree of myopia present. Higher levels of myopia are associated with increased risk of pathological complications but it is important to note that there is no safe level of myopia. Even low levels of myopia increase the risk of retinal detachment and other ocular comorbidities which will be discussed in detail later. The most serious complication, myopic maculopathy, is the only leading cause of blindness without an established treatment and therefore leads to inevitable loss of vision in some myopes, even at a young age. AIM: To highlight the current myopia epidemic and the sight threatening complications associated with it. DESIGN: This is a commissioned review article. Data were gathered by performing a literature review, searching the PubMed database for recent articles regarding myopia. CONCLUSIONS: Myopia is a potentially blinding disease. By identifying at risk individuals and intervening before they become myopic, eye care practitioners can prevent or delay spectacle use, reduce the risk of the myriad of myopic complications, thereby improve the patient's quality of life and positively impact its socio-economic effects.

BACKGROUND: Impaired neuropsychological functioning is a feature of major depression. Previous studies have suggested that at least some aspects of neuropsychological functioning improve with successful treatment of major depression. The extent to which medications may affect the degree of normalization of these functions is unclear. The aim of the current study was to examine the course of neuropsychological functioning during treatment of major depression with cognitive-behaviour therapy (CBT) or schema therapy (ST). METHOD: A total of 69 out-patients with a primary diagnosis of major depression and 58 healthy controls completed mood ratings, neuropsychological measures, and measures of emotional processing at baseline and after 16 weeks. Participants were randomized after baseline assessment to a year-long course of CBT or ST. Patients reassessed at 16 weeks were medication-free throughout the study. RESULTS: Significant neuropsychological impairment was evident at baseline in depressed participants compared with healthy controls. After 16 weeks of psychotherapy, mean depression rating scores fell more than 50%. However, no neuropsychological measures showed convincing evidence of significant improvement and emotional processing did not change. CONCLUSIONS: Persisting impairment in neuropsychological functioning after the first 16 weeks of CBT or ST suggests a need to modify psychological treatments to include components targeting cognitive functioning.

Infection of the human host by schistosome parasites follows exposure of skin to free-swimming cercariae and is aided by the release of excretory/secretory (E/S) material, which is rich in proteases and glycoconjugates. This material provides the initial stimulus to cells of the innate immune system. The study presented here is the first to examine human innate/early immune responsiveness to cercarial E/S in subjects from an area co-endemic for Schistosoma mansoni and S. haematobium. We report that in infected participants, stimulation of whole-blood cultures with cercarial E/S material (termed 0-3 hRP) caused the early (within 24 h) release of greater quantities of regulatory IL-10, compared with uninfected controls. Elevated levels of IL-10 but not pro-inflammatory TNFα or IL-8 were most evident in participants co-infected with S. mansoni and S. haematobium and were accompanied by a higher 0-3 h RP-specific IL-10: TNFα ratio. We also report that glycosylated components within 0-3 h RP appear to be important factors in the stimulation of IL-8, TNFα and IL-10 production by whole-blood cells.

The genetic, biological, and environmental backgrounds of an organism fundamentally influence the balance between risk and resilience to stress. Sex, age, and environment transact with responses to trauma in ways that can mitigate or exacerbate the likelihood that post-traumatic stress disorder will develop. Translational approaches to modeling affective disorders in animals will ultimately provide novel treatments and a better understanding of the neurobiological underpinnings behind these debilitating disorders. The extant literature on trauma/stress has focused predominately on limbic and cortical structures that innervate the hypothalamic-pituitary-adrenal axis and influence glucocorticoid-mediated negative feedback. It is through these neuroendocrine pathways that a self-perpetuating fear memory can propagate the long-term effects of early life trauma. Recent work incorporating translational approaches has provided novel pathways that can be influenced by early life stress, such as the glucocorticoid receptor chaperones, including FKBP51. Animal models of stress have differing effects on behavior and endocrine pathways; however, complete models replicating clinical characteristics of risk and resilience have not been rigorously studied. This review discusses a four-factor model that considers the importance of studying both risk and resilience in understanding the developmental response to trauma/stress. Consideration of the multifactorial nature of clinical populations in the design of preclinical models and the application of preclinical findings to clinical treatment approaches comprise the core of translational reciprocity, which is discussed in the context of the four-factor model.

BACKGROUND: Parasitic helminths have been shown to reduce inflammation in most experimental models of allergic disease, and this effect is mediated via cytokine responses. However, in humans, the effects of controlled helminth infection on cytokine responses during allergy have not been studied. OBJECTIVE: The aim was to investigate whether infection with the nematode parasite Trichuris suis alters systemic cytokine levels, cellular cytokine responses to parasite antigens and pollen allergens and/or the cytokine profile of allergic individuals. METHODS: In a randomized double-blinded placebo-controlled clinical trial (UMIN trial registry, Registration no. R000001298, Trial ID UMIN000001070, URL: http://www.umin.ac.jp/map/english), adults with grass pollen-induced allergic rhinitis received three weekly doses of 2500 Trichuris suis ova (n = 45) or placebo (n = 44) over 6 months. IFN-γ, TNF-α, IL-4, IL-5, IL-10 and IL-13 were quantified via cytometric bead array in plasma. Cytokines, including active TGF-ß, were also quantified in supernatants from peripheral blood mononuclear cells cultured with parasite antigens or pollen allergens before, during and after the grass pollen season for a sub-cohort of randomized participants (T. suis ova-treated, n = 12, Placebo-treated, n = 10). RESULTS: Helminth infection induced a Th2-polarized cytokine response comprising elevated plasma IL-5 and parasite-specific IL-4, IL-5 and IL-13, and a global shift in the profile of systemic cytokine responses. Infection also elicited high levels of the regulatory cytokine IL-10 in response to T. suis antigens. Despite increased production of T. suis-specific cytokines in T. suis ova-treated participants, allergen-specific cytokine responses during the grass pollen season and the global profile of PBMC cytokine responses were not affected by T. suis ova treatment. CONCLUSIONS AND CLINICAL RELEVANCE: This study suggests that cytokines induced by Trichuris suis ova treatment do not alter allergic reactivity to pollen during the peak of allergic rhinitis symptoms.

BACKGROUND: The occurrence of Tribulus terrestris motor neurone disease (MND) in sheep is linked with grazing Tribulus growing on cultivation paddocks. A previous survey found that the molybdenum (Mo) content of Tribulus growing on uncultivated soils in the Coonabarabran district of New South Wales was 3.03 ppm, but on cultivated soils it was <0.04 ppm. Tribulus contains the purine, xanthosine, which functions as a neuromodulator, and the catabolism of xanthosine is Mo-dependent. DESIGN: To investigate the relationship between xanthosine ingestion and low Mo concentration, eight sheep were fed Mo-deficient lucerne chaff (<0.10 ppm), the Mo antagonist, sodium tungstate, and xanthosine (25 mg/kg/day) over 18 weeks and then returned to pasture. RESULTS: Signs of MND developed in two sheep 30 months later and astrocyte degeneration occurred in all sheep. CONCLUSION: The findings were similar to those observed in sheep with T. terrestris MND, suggesting that the combination of xanthosine ingestion and Mo deficiency may be the cause of this disorder.

Schistosoma haematobium antigen recognition profiles of the human isotypes IgA, IgE, IgG1 and IgG4 were compared by image analysis of western blots. Adult worm antigens separated by two-dimensional gel electrophoresis were probed with pooled sera from Zimbabweans resident in a S. haematobium endemic area, followed by the identification of individual antigenic parasite proteins using mass spectrometry. Overall, IgG1 reacted with the largest number of antigens, followed by IgE and IgA which detected the same number, while IgG4 detected the fewest antigens. IgE recognized all antigens reactive with IgG4 as well as an additional four antigens, an isoform of 28-kDa GST, phosphoglycerate kinase, actin 1 and calreticulin. IgG1 additionally recognized fatty acid-binding protein, triose-phosphate isomerase and heat shock protein 70, which were not recognized by IgA. Recognition patterns varied between some isoforms, e.g. the two fructose 1-6-bis-phosphate aldolase isoforms were differentially recognized by IgA and IgG1. Although the majority of S. haematobium adult worm antigens are recognized by all of the four isotypes, there are clear restrictions in antibody recognition for some antigens. This may partly explain differences observed in isotype dynamics at a population level. Differential recognition patterns for some isoforms indicated in the study have potential importance for vaccine development.

Similarities in the immunobiology of different parasitic worm infections indicate that co-evolution of humans and helminths has shaped a common anti-helminth immune response. However, recent in vitro and immuno-epidemiological studies highlight fundamental differences and plasticity within host-helminth interactions. The 'trade-off' between immunity and immunopathology inherent in host immune responses occurs on a background of genetic polymorphism, variable exposure patterns and infection history. For the parasite, variation in life-cycle and antigen expression can influence the effector responses directed against them. This is particularly apparent when comparing gastrointestinal and tissue-dwelling helminths. Furthermore, insights into the impact of anti-helminthic treatment and co-infection on acquired immunity suggest that immune heterogeneity arises not from hosts and parasites in isolation, but also from the environment in which immune responses develop. Large-scale differences observed in the epidemiology of human helminthiases are a product of complex host-parasite-environment interactions which, given potential for exposure to parasite antigens in utero, can arise even before a parasite interacts with its human host. This review summarizes key differences identified in human acquired immune responses to nematode and trematode infections of public health importance and explores the factors contributing to these variations.

The aim of this study was to investigate facial expression recognition (FER) accuracy in social phobia and in particular to explore how facial expressions of emotion were misclassified. We hypothesised that compared with healthy controls, subjects with social phobia would be no less accurate in their identification of facial emotions (as reported in previous studies) but that they would misclassify facial expressions as expressing threatening emotions (anger, fear or disgust). Thirty individuals with social phobia and twenty-seven healthy controls completed a FER task which featured six basic emotions morphed using computer techniques between 0 percent (neutral) and 100 percent intensity (full emotion). Supporting our hypotheses we found no differences between the groups on measures of the accuracy of emotion recognition but that compared with healthy controls the social phobia group were more likely both to misclassify facial expressions as angry and to interpret neutral facial expressions as angry. The healthy control group were more likely to misclassify neutral expressions as sad. The importance of the role of these biases in social phobia needs further replication but may help in understanding the disorder and provide an interesting area for future research and therapy.

A new form of toxicity called equine fescue oedema is described. The clinical signs included inappetence, depression, and subcutaneous oedema of the head, neck, chest and abdomen. Affected horses had very low plasma albumin values. The toxicity affected 48 of 56 horses on six farms in different states of Australia, and 4 horses have died. All horses were grazing pastures that had been sown with varieties of Mediterranean tall fescue (Festuca arundinacea) that carry the endophyte known as Max P or Max Q. It is proposed that a pyrrolizidine alkaloid, N-acetyl norloline, which is produced by the Max P endophyte, may be responsible for this new toxicity in horses.

There have been anecdotal reports since 1962 of 'staggers' in sheep grazing Romulea rosea infested pastures, but this is the first detailed account. In September 2005, a locomotor disorder developed in 12 of 120 Merino wethers that had grazed R. rosea infested pasture at Albury, New South Wales, over several months. Affected sheep displayed signs that included limb paresis, knuckling over in the fetlocks, fine head tremor, incoordination, and an equilibrium disturbance characterised by frequent falling. The microscopic examination of brain and spinal cord tissues from two affected sheep revealed mild vacuolation, occasional lymphocytic cuffing around blood vessels, mild Wallerian degeneration, and occasional glial cells that contained honey-brown cytoplasmic pigments. The most significant changes were found in the cerebellum, where there were decreased numbers of Purkinje cells, increased numbers of glial cells, scattered vacuoles and occasional swollen axons. Previous reports of cerebellar toxicoses in ruminants have involved goats and cattle and have been associated with the ingestion of six Solanum spp. The Purkinje cell loss in this type of disorder is ultimately extensive and consequently affected animals may survive, but will remain permanently disabled.

OBJECTIVE: To observe the clinical signs of sheep affected by Tribulus terrestris motor neuron disease, to ascertain their response to striatal dopamine reducing drugs, and to examine their brains and spinal cords for microscopic changes. PROCEDURES: Twenty-eight sheep displaying well developed clinical signs of the disorder were observed. Twenty-two of these and 22 normal sheep were then randomly allocated to three groups and treated with diazepam, chlorpromazine, or xylazine. The time that it took an animal to return to a standing position following drug administration was recorded. The brain and complete spinal cord were removed from each of the other six affected sheep and fixed in formalin. Brains were sectioned throughout at 5 mm intervals and spinal cords at 10 mm intervals. All tissues were paraffin embedded and examined by light microscopy. A few samples were examined by electron microscopy. RESULTS: Clinical signs included postural asymmetry with a right:left body-side dominance within the group of 50:50, unequal flaccid paresis in the pelvic limbs, extensor muscle atrophy and adduction of the weaker pelvic limb, and concurrent abduction of the stronger. Forward motion followed either a fixed left or right hand curved trajectory, the sheep no longer being able to choose which. Twelve animals intermittently displayed rotational behaviour that involved loss of postural balance without locomotor activation. The administration of diazepam, chlorpromazine, or xylazine caused limb paresis and sedation, with affected sheep being slower than normal sheep by factors of 8, 3 and 2 respectively, to return to a standing position. There were scattered areas of mild Wallerian degeneration throughout the spinal cord, and in both the brain and the cord there were small numbers of degenerate astrocytes containing novel cytoplasmic pigment granules. CONCLUSIONS: Affected sheep had a dysfunction in the control of directional change and this provides a new insight into the normal mechanism for 'turning' in quadrupeds. Directional change requires a functional asymmetry or lateralisation within the upper motor neuron to accommodate a difference in the rate of forward progression of each body side and, simultaneously, a lateral shift of the centre of gravity. The sensitivity of affected sheep to diazepam is consistent with a pre-existing elevation in GABAergic neuronal inhibition, probably as a result of a reduction in glutamatergic neuronal excitation. The cytoplasmic pigment found in degenerate astrocytes was novel and its presence in the brain nuclei known to contribute to turning behaviour could have aetiological significance. The motor output of the basal ganglia in Tribulus neurotoxicity appeared to be excessively inhibitory to the pelvic limb extensor muscles and was asymmetric, causing fixation of the turning posture but not locomotor activation. An intoxication of specific purine sensitive, glutamate releasing astrocytes, located in nuclei controlling turning, was suspected.

OBJECTIVE: To investigate the clinical effect of administering sufficient Hypericum perforatum to cattle to deliver quadruple the reported oral toxic dose. ANIMALS: Thirty-six yearling Hereford (n = 18) and Angus (n = 18) steers. DESIGN: A series of six experiments was conducted, each using 12 animals in a 2 x 2 factorial design, with two breeds of cattle (Hereford, Angus) and two dose levels of hypericin, 1.5 mg/kg (treated group) and 0 mg/kg (control group). Each set of 12 steers was used in duplicate experiments, with all animals alternated between treated and control groups. PROCEDURES: Treated groups received finely milled H. perforatum administered orally in gelatin capsules to provide 1.5 mg hypericin/kg body weight. All cattle were then exposed to direct sunlight for 5 h per day for 5 successive days. Rectal temperatures were measured immediately before and at the end of each sunlight exposure session. Rectal temperature above 40 degrees C, together with some other clinical sign of hypericin poisoning, was considered indicative of intoxication. RESULTS: No animals developed a rectal temperature above 40 degrees C or other clinical signs of hypericin poisoning. CONCLUSIONS: While the reported bovine oral toxic dose of 3 g dried plant/kg body weight, for flowering stage, presumed narrow leaved biotype, H. perforatum, is probably correct, the corresponding dose for hypericin of 0.37 mg/kg is incorrect. Based on its known concentration in this plant the toxic dose of hypericin for partially pigmented Hereford-cross cattle is estimated at about 10.5 mg/kg body weight and more than this for fully pigmented cattle. This would imply that cattle of the former type should be about three and a half times better protected against H. perforatum toxicity than are unpigmented, wool protected, Merino sheep. Cattle, particularly if fully pigmented, may have a role in grazing management to control H. perforatum.

In past papers, a notion emerged that space had elements common to the energy of atomic shells to which it could flow by paths to control metabolic energy of animate systems. This paper examines several authors on the structure and function of space energy wave bundle flows seeking mechanisms for metabolic control. The application of time to these waves provides two compartments, time symmetric and time asymmetric, respectively imaginary and real, in a sensitively balanced state as part of a specific system from space to orbits. Disturbance to the balance, where minimal, results in a reflection outside the system to the heat bath consistent with physiology. Arbitrarily more than minimal, results in pathology. A black-hole-like monitor maintains the balance in alliance with a multi-system space stream, the meridian of traditional Chinese medicine. This macroscopic state is now consistent with manipulation using conventional electronics, by way of remedy.

Assimilation of many concepts and observations on an energy force providing a control over metabolic chemical interaction with a force in space itself is possible. The force is assumed to integrate with the atomic orbits of the metabolic chemicals, leaving its path from space as a fluctuation for realisation of two components, a non-linear space-rich part and a linear space-poor part. The pair are associated by a balance leading to non-linear behaviour imposed upon an otherwise linear output of the orbital energy and the actual control is vested in the balance. Examples are cited for the integration of the fluctuation during protein and nucleoprotein function and for cyto-structural mechanisms which may allow a selection of space elements to provide for evolution of unique family elements for enhanced control, much as the optical physicists have selected squeezed light elements for refined quantal function. Methods for rational therapies emerge from these refinements.
