Background
Patients with psychiatric disorders often experience cognitive dysfunction, but the precise relationship between cognitive deficits and psychopathology remains unclear. We investigated the relationships between domains of cognitive functioning and psychopathology in a transdiagnostic sample using a data-driven approach.
MethodsCross-sectional network analyses were conducted to investigate the relationships between domains of psychopathology and cognitive functioning and detect clusters in the network. This naturalistic transdiagnostic sample consists of 1016 psychiatric patients who have a variety of psychiatric diagnoses, such as depressive disorders, anxiety disorders, obsessive−compulsive and related disorders, and schizophrenia spectrum and other psychotic disorders. Psychopathology symptoms were assessed using various questionnaires. Core cognitive domains were assessed with a battery of automated tests.
ResultsNetwork analysis detected three clusters that we labelled: general psychopathology, substance use, and cognition. Depressive and anxiety symptoms, verbal memory, and visual attention were the most central nodes in the network. Most associations between cognitive functioning and symptoms were negative, i.e. increased symptom severity was associated with worse cognitive functioning. Cannabis use, (subclinical) psychotic experiences, and anhedonia had the strongest total negative relationships with cognitive variables.
ConclusionsCognitive functioning and psychopathology are independent but related dimensions, which interact in a transdiagnostic manner. Depression, anxiety, verbal memory, and visual attention are especially relevant in this network and can be considered independent transdiagnostic targets for research and treatment in psychiatry. Moreover, future research on cognitive functioning in psychopathology should take a transdiagnostic approach, focusing on symptom-specific interactions with cognitive domains rather than investigating cognitive functioning within diagnostic categories.

We describe a fronto-temporal paroxysmal rhythmic activity registered by magnetoencephalography (MEG) in two patients with obsessive compulsive disorder (OCD) without SSRIs treatment. The localization of the activity involves cingulate cortex and frontal areas. We think that these MEG findings are related to the disease itself, rather than representing pharmacological SSRIs effect.

Meiotic maturation of oocytes requires a variety of ATP-dependent reactions, such as germinal vesicle breakdown, spindle formation, and rearrangement of plasma membrane structure, which is required for fertilization. Mitochondria are accordingly expected be localized to subcellular sites of energy utilization. Although microtubule-dependent cellular traffic for mitochondria has been studied extensively in cultured neuronal (and some other somatic) cells, the molecular mechanism of their dynamics in mammalian oocytes at different stages of maturation remains obscure. The present work describes dynamic aspects of mitochondria in porcine oocytes at the germinal vesicle stage. After incubation of oocytes with MitoTracker Orange followed by centrifugation, mitochondria-enriched ooplasm was obtained using a glass needle and transferred into a recipient oocyte. The intracellular distribution of the fluorescent mitochondria was then observed over time using a laser scanning confocal microscopy equipped with an incubator. Kinetic analysis revealed that fluorescent mitochondria moved from central to subcortical areas of oocytes and were dispersed along plasma membranes. Such movement of mitochondria was inhibited by either cytochalasin B or cytochalasin D but not by colcemid, suggesting the involvement of microfilaments. This method of visualizing mitochondrial dynamics in live cells permits study of the pathophysiology of cytoskeleton-dependent intracellular traffic of mitochondria and associated energy metabolism during meiotic maturation of oocytes.

López Arteaga MT, Amo C, Sánchez Morla EM, Sánchez Román M. Induced psychosis after withdrawal of varenicline: a case report.
Objective: Varenicline has been associated with psychiatric side effects, and cases with psychotic symptoms during treatment have been reported, few of them after the withdrawal. We describe a case with no current or previous medical or psychiatric history.
Method: A single case report.
Results: The patient without previous psychiatric pathology, following the withdrawal of treatment with varenicline, experiences delirium and behavioural disturbances. There was a remission of symptoms after 3 weeks of treatment with risperidone.
Conclusion: Discontinuation of treatment with varenicline due to poor tolerance for side effects (nausea and insomnia) could trigger psychotic symptoms in subjects with no personal or family psychiatric history.

The increasing demand for food from limited available land, in light of declining soil fertility and future threats of climate variability and change have increased the need for more sustainable crop management systems. Conservation agriculture (CA) is based on the three principles of minimum soil disturbance, surface crop residue retention and crop rotations, and is one of the available options. In Southern Africa, CA has been intensively promoted for more than a decade to combat declining soil fertility and to stabilize crop yields. The objective of this review is to summarize recent advances in knowledge about the benefits of CA and highlight constraints to its widespread adoption within Southern Africa. Research results from Southern Africa showed that CA generally increased water infiltration, reduced soil erosion and run-off, thereby increasing available soil moisture and deeper drainage. Physical, chemical and biological soil parameters were also improved under CA in the medium to long term. CA increased crop productivity and also reduced on-farm labor, especially when direct seeding techniques and herbicides were used. As with other cropping systems, CA has constraints at both the field and farm level. Challenges to adoption in Southern Africa include the retention of sufficient crop residues, crop rotations, weed control, pest and diseases, farmer perception and economic limitations, including poorly developed markets. It was concluded that CA is not a ‘one-size-fits-all’ solution and often needs significant adaptation and flexibility when implementing it across farming systems. However, CA may potentially reduce future soil fertility decline, the effects of seasonal dry-spells and may have a large impact on food security and farmers’ livelihoods if the challenges can be overcome.

Aim
The aim was to identify similarities and differences between private practice and the National Health Service (NHS) in practitioners’ experiences of delivering acupuncture to treat pain. We wished to identify differences that could affect patients’ experiences and inform our understanding of how trials conducted in private clinics relate to NHS clinical practice.
BackgroundAcupuncture is commonly used in primary care for lower back pain and is recommended in the National Institute for Health and Clinical Excellence's guidelines. Previous studies have identified differences in patients’ accounts of receiving acupuncture in the NHS and in the private sector. The major recent UK trial of acupuncture for back pain was conducted in the private sector.
MethodsSemi-structured qualitative interviews were conducted with 16 acupuncturists who had experience of working in the private sector (n = 7), in the NHS (n =3), and in both the sectors (n = 6). The interviews lasted between 24 and 77 min (median=49 min) and explored acupuncturists’ experiences of treating patients in pain. Inductive thematic analysis was used to identify similarities and differences across private practice and the NHS.
FindingsThe perceived effectiveness of acupuncture was described consistently and participants felt they did (or would) deliver acupuncture similarly in NHS and in private practice. In both the sectors, patients sought acupuncture as a last resort and acupuncturist–patient relationships were deemed important. Acupuncture availability differed across sectors: in the NHS it was constrained by Trust policies and in the private sector by patients’ financial resources. There were greater opportunities for autonomous practice in the private sector and regulation was important for different reasons in each sector. In general, NHS practitioners had Western-focussed training and also used conventional medical techniques, whereas private practitioners were more likely to have Traditional Chinese training and to practise other complementary therapies in addition to acupuncture. Future studies should examine the impact of these differences on patients' clinical outcomes.

The crystal structure of Bi2Zn2/3Nb4/3O7 was determined using a combination of electron, x-ray, and neutron powder diffraction. The compound crystallizes with a monoclinic zirconolite-like structure [C2/c (No.15) space group, a = 13.1037(9) Å, b = 7.6735(3) Å, c = 12.1584(6) Å, β = 101.318(5)°]. According to structural refinement using neutron diffraction data, Nb preferentially occupies six-fold coordinated sites in octahedral sheets parallel to the (001) planes, while Zn is statistically distributed between two half-occupied (5 + 1)-fold coordinated sites near the centers of six-membered rings of [Nb(Zn)O6] octahedra. The Nb/Zn cation layers alternate along the c-axis with Bi-layers, in which Bi cations occupy both eight- and seven-fold coordinated sites. The eight-fold coordinated Bi atoms exhibited strongly anisotropic thermal displacements with an abnormally large component directed approximately along the c-axis (normal to the octahedral layers).

Background. Self-asphyxiation using car exhaust gas is a common method of suicide in England and Wales, particularly in young males. The introduction of catalytic converters has reduced the toxicity of car exhausts. The main aims of the study were: to seek evidence of a fall in car exhaust suicides in the general population and in age and gender groups; to relate any fall to changes in car exhaust systems, particularly since legislation on car exhaust emissions in 1993; and to examine rates of suicide by other methods for evidence of method substitution.
Methods. Population study in England and Wales using national suicide statistics for 1987 to 1998.
Results. There was a fall in suicide by car exhaust asphyxiation in all age and gender groups. This change was most marked after 1993. The overall population suicide rate (all methods) also fell but there was no overall change in suicides by young males or females. In these groups suicide by hanging increased.
Conclusions. Legislation on catalytic converters appears to have contributed to a fall in car exhaust suicides. However, the effect on overall suicide rates in young people has been reduced by method substitution.

Background. Suicide prevention is a health priority in many countries. Improved management of suicide risk may improve suicide prevention. This study aimed to assess the feasibility of health district-wide training in the assessment and management of people at risk of suicide; and to assess the impact of training on assessment and management skills.
Methods. Staff in three health care settings, namely primary care, accident and emergency departments and mental health services (N = 359), were offered suicide risk management training in a district-wide programme, using a flexible ‘facilitator’ approach. The main outcomes were the rate of attendance at training, and changes in suicide risk assessment and management skills following training.
Results. It was possible to deliver training to 167 health professionals (47% of those eligible) during a 6 month training period. This included 95 primary care staff (39%), 21 accident and emergency staff (42%) and 51 mental health staff (78%). Of these, 103 (69%) attended all training. A volunteer sample of 28 staff who underwent training showed improvements in skills in the assessment and management of suicide risk. Satisfaction with training was high. The expected costs of district-wide training, if it were able to produce a 2·5% reduction in the suicide rate, would be £99747 per suicide prevented and £3391 per life year gained.
Conclusions. Training in the assessment and management of suicide risk can be delivered to approximately half the targeted staff in primary care, accident and emergency departments and mental health services. The current training package can improve skills and is well accepted. If it were to produce a modest fall in the suicide rate, such training would be cost-effective. However, a future training programme should develop a broader training package to reach those who will not attend.

A design-of-experiments methodology was implemented to assess the commercial equipment viability to fabricate the high-K dielectrics Ta2O5, TiO2 and BST (70/30 and 50/50 compositions) for use as gate dielectrics. The high-K dielectrics were annealed in 100% or 10% O2 for different times and temperatures in conjunction with a previously prepared NH3 nitrided or 14N implanted silicon surface. Five metal electrode configurations—Ta, TaN, W, WN and TiN—were concurrently examined. Three additional silicon surface configurations were explored in conjunction with a more in-depth set of time and temperature anneals for Ta2O5. Electrical characterization of capacitors fabricated with the above high-K gate dielectrics, as well as SIMS and TEM analysis, indicate that the post high-K deposition annealing temperature was the most significant variable impacting the leakage current density, although there was minimal influence on the capacitance. Further studies are required, however, to clarify the physical mechanisms underlying the electrical data presented.

Copper surfaces were derivatized resulting in the formation of Mx[Cu(II)(CN)Fe(II/III)(CN)5] at the interface. Polyimides were spin coated onto the modified metal surfaces and the degree of adhesion measured by the tape pull test. Effects of mechanical interlocking were evident in the case of modified copper samples, due to derivatization by ferricyanide. The chemical bonding and elemental analyses of the interfaces were studied by XPS and SEM.
