Abstract
Funding Acknowledgements
Type of funding sources: None.
Background
Suicide and euthanasia accounts for 14.3% of deaths in those with psychiatric conditions. The rest are attributed to preventable causes such as cardiovascular disease, respiratory disease, and infections. Several psychotropic medications have been associated with sudden death due to their effect on prolonging QT interval, resulting in the development of a polymorphic ventricular arrhythmia, Torsades de Pointes (TdP). TdP may be self-limiting or lead to sudden cardiac arrest and death.
Purpose
This study aims to evaluate the cardiotoxic effects of psychotropic medications.
Method
This is a descriptive retrospective study of patients submitted to the local psychiatric wards within one year. Patients with psychotropic drug prescriptions were included while patients below 18 years old, pregnant, or did not have ECG performed were excluded. The control group consisted of sex- and age- matched patients with ECG conducted for occupational health purposes. Multiple regression models were conducted to investigate the predictors of significant ECG differences.
Result
Of the 154 psychiatric inpatients admitted, exclusions were 44 patients due to exclusion criteria and 19 patients due to difficulty in physical file access. The study population (n = 91) had a mean age of 36.7 years old with 40.7% female and 59.3% male. The predominant diagnoses were schizophrenia and delusional disorders (58.2%). 86 psychiatric patients (94.5%) were prescribed antipsychotic drugs (APD).
A significantly higher proportion of psychiatric patients has a history of smoking (p < 0.001), alcohol consumption (p = 0.001), and illicit drug use (p < 0.001). They also exhibited significantly more co-morbid illnesses including hypertension (p = 0.022), hyperlipidaemia (p = 0.013), diabetes (p = 0.026) and thyroid disease (p = 0.023) than the control population.
Psychiatric patients had a significantly higher mean heart rate (79.9 vs 69.6 ms; p < 0.001) and QTc interval (452.2 vs 418.6ms; p < 0.001). Mean QTc interval was significantly longer for psychiatric patients in both male (454.2 vs 414.5ms; p < 0.001) and female (449.3 vs 425.6 ms; p = 0.029) gender. Psychotropic drug use is a significant predictor for both prolonged heart rate (p < 0.001) and prolonged QTc interval (p < 0.001). Electrolyte imbalance is a significant predictor of prolonged QTc interval only (p = 0.036). One year follow of both groups detected only 1 psychiatric patient with palpitation.
Conclusion
Psychiatric patients on psychotropic medications have a longer baseline heart rate and QTc interval, which was not associated with MACE at 1 year. None of the underlying comorbidities and lifestyle choices were significant predictors of this. Electrolyte abnormalities and psychotropic drug use significantly predicted QTc prolongation. However, these findings were largely driven by APD use. A follow-up study of a longer period is recommended to investigate whether patients with prolonged QTc interval are of higher risk of MACE occurrence.

Abstract
BACKGROUND To review whether online decision aids are available for patients contemplating pelvic exenteration (PE) for locally advanced and recurrent rectal cancer (LARC and LRRC). METHODS A grey literature review was carried out using the Google Search™ engine undertaken using a predefined search strategy (PROSPERO database CRD42019122933). Written health information was assessed using the DISCERN criteria and International Patient Decision Aids Standards (IPDAS) with readability content assessed using the Flesch-Kincaid reading ease test and Flesch-Kincaid grade level score. RESULTS Google search yielded 27, 782, 200 results for the predefined search criteria. 131 sources were screened resulting in the analysis of 6 sources. No sources were identified as a decision aid according to the IPDAS criteria. All sources provided an acceptable quality of written health information, scoring a global score of 3 for the DISCERN written assessment. The median Flesch-Kincaid reading ease was 50.85 (32.5-80.8) equating to a reading age of 15-18 years and the median Flesch-Kincaid grade level score was 7.65 (range 3-9.7), which equates to a reading age of 13-14. CONCLUSIONS This study has found that there is a paucity of online information for patients contemplating PE. Sources that are available are aimed at a high health literate patient. Given the considerable morbidity associated with PE surgery there is a need for high quality relevant information in this area. A PDA should be developed to improve decision making and ultimately improve patient experience.

Abstract
Background: As e-cigarette popularity has increased, there is growing evidence to suggest that while they are highly likely to be considerably less harmful than cigarettes, their use is not free of risk to the user. There is therefore an ongoing need to characterise the chemical composition of e-cigarette aerosols, as a starting point in characterising risks associated with their use. This study examined the chemical complexity of aerosols generated by an e-cigarette containing one unflavored and three flavored e-liquids. A combination of targeted and untargeted chemical analysis approaches was used to examine the number of compounds comprising the aerosol. Contributions of e-liquid flavors to aerosol complexity were investigated, and the sources of other aerosol constituents sought. Emissions of 98 aerosol toxicants were quantified and compared to those in smoke from a reference tobacco cigarette generated under two different smoking regimes. Results: Combined untargeted and targeted aerosol analyses identified between 94 and 139 compounds in the flavored aerosols, compared with an estimated 72-79 in the unflavored aerosol. This is significantly less complex (by 1-2 orders of magnitude) than the reported composition of cigarette smoke. Combining both types of analysis identified 5-12 compounds over and above those found by untargeted analysis alone. Gravimetrically, 89-99% of the e-cigarette aerosol composition was composed of glycerol, propylene glycol, water and nicotine, and around 3% comprised other, more minor, constituents. Comparable data for the Ky3R4F reference tobacco cigarette pointed to 58-76% of cigarette smoke "tar" being composed of minor constituents. Levels of the targeted toxicants in the e-cigarette aerosols were significantly lower than those in cigarette smoke, with 68.5->99% reductions under ISO 3308 puffing conditions and 88.4->99% reductions under ISO 20778 (intense) conditions; reductions against the WHO TobReg 9 priority list were around 99%. Conclusion: These analyses showed that the e-cigarette aerosols contain fewer compounds and at significantly lower concentrations than cigarette smoke. The chemical diversity of an e-cigarette aerosol is strongly impacted by the choice of e-liquid ingredients.

Abstract
Purpose HER2-targeted therapies have substantially improved the outcome of patients with breast cancer, however, they can be associated with cardiac toxicity. Guidelines recommend holding HER2-targeted therapies until resolution of cardiac dysfunction. SAFE-HEaRt is the first trial that prospectively tests whether these therapies can be safely administered without interruptions in patients with cardiac dysfunction. Methods Patients with stage I–IV HER2-positive breast cancer candidates for trastuzumab, pertuzumab or ado-trastuzumab emtansine (TDM-1), with left ventricular ejection fraction (LVEF) 40–49% and no symptoms of heart failure (HF) were enrolled. All patients underwent cardiology visits, serial echocardiograms and received beta blockers and ACE inhibitors unless contraindicated. The primary endpoint was completion of the planned HER2-targeted therapies without developing either a cardiac event (CE) defined as HF, myocardial infarction, arrhythmia or cardiac death or significant asymptomatic worsening of LVEF. The study was considered successful if planned oncology therapy completion rate was at least 30%. Results Of 31 enrolled patients, 30 were evaluable. Fifteen patients were treated with trastuzumab, 14 with trastuzumab and pertuzumab, and 2 with TDM-1. Mean LVEF was 45% at baseline and 46% at the end of treatment. Twenty-seven patients (90%) completed the planned HER2-targeted therapies. Two patients experienced a CE and 1 had an asymptomatic worsening of LVEF to ≤ 35%. Conclusion This study provides safety data of HER2-targeted therapies in patients with breast cancer and reduced LVEF while receiving cardioprotective medications and close cardiac monitoring. Our results demonstrate the importance of collaboration between cardiology and oncology providers to allow for delivery of optimal oncologic care to this unique population.

Abstract
OBJECTIVE There are variable reports of risk of concordance for progression to islet autoantibodies and type 1 diabetes in identical twins after one twin is diagnosed. We examined development of positive autoantibodies and type 1 diabetes and the effects of genetic factors and common environment on autoantibody positivity in identical twins, nonidentical twins, and full siblings. RESEARCH DESIGN AND METHODS Subjects from the TrialNet Pathway to Prevention Study (N = 48,026) were screened from 2004 to 2015 for islet autoantibodies (GAD antibody [GADA], insulinoma-associated antigen 2 [IA-2A], and autoantibodies against insulin [IAA]). Of these subjects, 17,226 (157 identical twins, 283 nonidentical twins, and 16,786 full siblings) were followed for autoantibody positivity or type 1 diabetes for a median of 2.1 years. RESULTS At screening, identical twins were more likely to have positive GADA, IA-2A, and IAA than nonidentical twins or full siblings (all P < 0.0001). Younger age, male sex, and genetic factors were significant factors for expression of IA-2A, IAA, one or more positive autoantibodies, and two or more positive autoantibodies (all P ≤ 0.03). Initially autoantibody-positive identical twins had a 69% risk of diabetes by 3 years compared with 1.5% for initially autoantibody-negative identical twins. In nonidentical twins, type 1 diabetes risk by 3 years was 72% for initially multiple autoantibody-positive, 13% for single autoantibody-positive, and 0% for initially autoantibody-negative nonidentical twins. Full siblings had a 3-year type 1 diabetes risk of 47% for multiple autoantibody-positive, 12% for single autoantibody-positive, and 0.5% for initially autoantibody-negative subjects. CONCLUSIONS Risk of type 1 diabetes at 3 years is high for initially multiple and single autoantibody-positive identical twins and multiple autoantibody-positive nonidentical twins. Genetic predisposition, age, and male sex are significant risk factors for development of positive autoantibodies in twins.

Abstract
Aims To evaluate the incidence of primary venous thromboembolism (VTE), epidural haematoma, surgical site infection (SSI), and 90-day mortality after elective spinal surgery, and the effect of two protocols for prophylaxis. Patients and Methods A total of 2181 adults underwent 2366 elective spinal procedures between January 2007 and January 2012. All patients wore anti-embolic stockings, mobilised early and were kept adequately hydrated. In addition, 29% (689) of these were given low molecular weight heparin (LMWH) while in hospital. SSI surveillance was undertaken using the Centers for Disease Control and Prevention criteria. Results In patients who only received mechanical prophylaxis, the incidence of VTE was 0.59% and that of SSI 2.1%. In patients who were additionally given LMWH, the incidence of VTE was 0% and that of SSI 0.7%. The unadjusted p-value was 0.04 for VTE and 0.01 for SSI. There were no cases of epidural haematoma or 90-day mortality in either group. When adjusted for case-mix, LMWH remained a significant factor (p = 0.006) for VTE, but not for SSI. Conclusion A peri-operative protocol involving mechanical anti-embolism stockings, adequate hydration, and early post-operative mobilisation is effective in significantly reducing the incidence of VTE. The addition of LMWH is safe in patients at higher risk of developing VTE. Cite this article: Bone Joint J 2017;99-B:1204–9.

Abstract
Considerable research in the early 1980s led to the identification of radiative heat transfer as a major contributor to the overall thermal conductivity of PU rigid foam. Fundamental heat transfer analysis showed that for foam model matrices in which the primary variable was cell-size, an approximately linear relationship was obtained between the radiative heat transfer thermal conductivity contribution λ rad and cell-size. λ rad, was shown to theoretically decrease to below 1 mW/mK when foam cell-sizes were reduced to about 50 μ. This decrease to below 1 mW/mK is considered in this presentation as an effective elimination of the radiative heat transfer mechanism. With the establishment of a phase-out timetable for R-11, considerable global research activity was focused on the development of fine celled technology capable of exploiting these predictions. In recent years technology for the production of closed cell foams with cell-sizes in the range 100-300 μ have been developed. More recently open celled foams have now been developed for vacuum panel applications with cell-sizes down to the 50 μ level. This series of foams provided a unique opportunity to determine directly the real level of radiative heat transfer that occurs and to therefore determine for the first time the real effectiveness of polyurethane foam matrices to attenuate radiative heat transfer. The theoretical framework for the investigation adopts what is known as a 3 flux approximation, which allows both absorption and scattering contributions to be taken into account. Spectral I-R directional-hemispherical transmission and reflection measurements were performed using an integrating sphere accessory on a BIORAD FTS-40 spectrometer equipped with a CsI beam splitter. The wavelength region of investigation covered 98% of the black body spectrum. From the experimental reflection and transmission spectra and the three flux approximation method, the spectral extinction coefficient was determined and then Rosseland averaged. From this Rosseland averaged extinction coefficient, the foam radiative thermal conductivity λ rad at a mean temperature of 283°C was calculated. Using a mean intercept length analysis of an SEM characterization of the foam both parallel and perpendicular to the symmetry axis, it was possible to determine the Z-average cell-size. Analysis of the results displayed a strong linear relationship of λ rad, with the Z-average foam cell size. It is shown that for the very fine open celled foams designed for vacuum panel applications, λ rad values below 1 mW/mK could be obtained. This remarkable level of radiative attenuation for PU foam, in combination with the expected thermal conductivity contribution from solid conduction, is shown to strongly support their suitability as potential vacuum insulation matrices.

Abstract
We report results from the first search for ν_{μ}→ν_{e} transitions by the NOvA experiment. In an exposure equivalent to 2.74×10^{20} protons on target in the upgraded NuMI beam at Fermilab, we observe 6 events in the Far Detector, compared to a background expectation of 0.99±0.11(syst) events based on the Near Detector measurement. A secondary analysis observes 11 events with a background of 1.07±0.14(syst). The 3.3σ excess of events observed in the primary analysis disfavors 0.1π<δ_{CP}<0.5π in the inverted mass hierarchy at the 90% C.L.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE After almost 50 years of international trade in wild harvested medicinal bark from Africa and Madagascar, the example of Prunus africana holds several lessons for both policy and practice in the fields of forestry, conservation and rural development. Due to recent CITES restrictions on P. africana exports from Burundi, Kenya and Madagascar, coupled with the lifting of the 2007 European Union (EU) ban in 2011, Cameroon's share of the global P. africana bark trade has risen from an average of 38% between 1995 and 2004, to 72.6% (658.6 metric tons) in 2012. Cameroon is therefore at the center of this international policy arena. METHODS AND MATERIALS This paper draws upon several approaches, combining knowledge in working with P. africana over a 30-year period with a thorough literature review and updated trade data with "ground-truthing" in the field in 2013 and 2014. This enabled the construction of a good perspective on trade volumes (1991-2012), bark prices (and value-chain data) and the gaps between research reports and practice. Two approaches provided excellent lenses for a deeper understanding of policy failure and the "knowing-doing gap" in the P. africana case. A similar approach to Médard's (1992) analyses of power, politics and African development was taken and secondly, studies of commodity chains that assess the power relations that coalesce around different commodities (Ribot, 1998; Ribot and Peluso, 2003). RESULTS Despite the need to conserve genetically and chemically diverse P. africana, wild populations are vulnerable, even in several "protected areas" in Burundi, Cameroon, the Democratic Republic of Congo and in the forest reserves of Madagascar. Secondly, hopes of decentralized governance of this forest product are misplaced due to elite capture, market monopolies and subsidized management regimes. At the current European price, for P. africana bark (US$6 per kg) for example, the 2012 bark quota (658.675t) from Cameroon alone was worth over US$3.9 million, with the majority of this accruing to a single company. In contrast to lucrative bark exports, the livelihood benefits and financial returns to local harvesters from wild harvest are extremely low. For example, in 2012, the 48 active harvesters working within Mount Cameroon National Park (MCNP) received less than 1US$ per day from bark harvests, due to a net bark price of 0.33 US$ per kg (or 43% of the farm gate price for wild harvested bark). In addition, the costs of inventory, monitoring and managing sustainable wild harvests are far greater than the benefits to harvesters. CONCLUSION Without the current substantial international donor subsidies, sustainable harvest cannot be sustained. What is required to supply the current and future market is to develop separate, traceable P. africana bark supply chains based on cultivated stocks. On-farm production would benefit thousands of small-scale farmers cultivating P. africana, including local women, for whom wild harvesting is too onerous. This change requires CITES and EU support and would catalyze P. africana cultivation in across several montane African countries and Madagascar, increasing farm-gate prices to harvesters compared to economic returns from wild harvest.

Abstract
BACKGROUND It is well recognised that management of young adults with type 1 diabetes (T1DM) poses difficult challenges for physicians and health care organisations as a whole. In Ireland and in particular the west of Ireland there has been little audit or research on young adults with T1DM and the services available to them. DESIGN In 2011 a retrospective review of this patient population in our territory referral centre was carried out. RESULTS The average glycaemic control in this population was poor at 81mmols/mol and diabetes related complications were present in 32%. Engagement by this population with services was poor with an average of 3 missed clinic appointments over a 24 month period. CONCLUSION These results have prompted a re think of how health care professionals can deliver a service that better suits the needs of this challenging patient group.

Abstract
BACKGROUND Sepsis is the most common manifestation of invasive pneumococcal disease and is characterized by a severe systemic inflammatory state that leads to circulatory compromise or end organ malperfusion or dysfunction. Patients suffering from sepsis often display low platelet counts characterized by thrombocytopenia as a result of platelet activation. OBJECTIVE To investigate the mechanism through which platelets become activated in sepsis upon binding to Streptococcus pneumoniae. PATIENTS AND METHODS We determined S. pneumoniae inducible platelet reactivity using light transmission aggregometry. Dense granule secretion was measured by luminometry using a luciferin/luciferase assay. RESULTS Streptococcus pneumoniae induced platelet aggregation in a strain-dependent manner. Induction of aggregation was not attributable to capsule serotype, as unencapsulated strains also induced platelet aggregation. Platelet aggregation was not associated with pneumolysin toxin, as a pneumolysin-deficient mutant of S. pneumoniae induced aggregation equally as well as the parent strain. Platelet aggregation also occurred in the absence of plasma proteins or antibody, and was GPIIbIIIa dependent but aspirin independent. Toll-like receptor 2 (TLR2) is present on platelets and acts as a receptor for gram-positive bacterial lipoteichoic acid and peptidoglycan. Inhibition of TLR2 but not TLR4 (also present on platelets) completely abolished platelet aggregation. S. pneumoniae-induced platelet aggregation resulted in activation of the PI3kinase/RAP1 pathway, leading to integrin GPIIbIIIa activation and dense granule release. CONCLUSIONS Our results demonstrate a novel interaction between S. pneumoniae and TLR2, which results in platelet activation that is likely to contribute to the thrombotic complications of sepsis.

MATERIALS AND METHODS A retrospective study reviewing the medical charts of 259 patients with multiple sclerosis, comparing patients continuing therapy for at least 3 years with those switching or stopping therapy. RESULTS Sixty 9% stopped (15%), or switched (54%), interferon-beta therapy within 3 years. Stoppers had longer disease duration before starting therapy (P = 0.002), less frequently relapsing-remitting multiple sclerosis (P = 0.046), and more often Expanded Disability Status Scale scores 6-9.5 (P = 0.045) compared to Switchers. The most common reasons for switching/stopping therapy were perceived lack of effect and side-effects. CONCLUSIONS Adherence to initial immune-modulating therapy is low; identification of patients at higher risk of stopping therapy and provision of adequate support are essential.

Abstract
BACKGROUND Soft-tissue injuries of the knee, mainly involving the anterior cruciate ligament (ACL), the medial collateral ligament (MCL) and menisci, are common and their rehabilitation after non-surgical or surgical treatment often involves intensive and prolonged physiotherapy. OBJECTIVES To examine the evidence for effectiveness of various physiotherapist-led (or 'directed') rehabilitation programmes, and of various interventions used within these programmes, for rehabilitation of acute or chronic ACL, MCL or meniscal injuries of the knee in adults. SEARCH STRATEGY We searched the Cochrane Musculoskeletal Injuries Group's specialised register (to June 2001), MEDLINE (from 1966 to August 1999), EMBASE (from 1980 to February 1997), CINAHL (1982 to April 1999), CURRENT CONTENTS (up to March 1999) and reference lists of relevant articles, and consulted colleagues. Date of the most recent search: June 2001. SELECTION CRITERIA Randomised or quasi-randomised clinical trials evaluating physiotherapist-led rehabilitation programmes, or components of rehabilitation programmes, for the treatment or post-surgical rehabilitation of ACL, MCL or knee meniscal injuries. Excluded were trials investigating electrical stimulation, or various interventions such as cryotherapy, immobilisation braces and continuous passive motion when used in initial or early treatment. Laboratory based trials reporting intermediate outcomes were also excluded. DATA COLLECTION AND ANALYSIS All trials, judged as fitting the selection criteria by two reviewers, were independently assessed by two reviewers for methodological quality by use of an 11 item checklist. Data were independently extracted by two reviewers. Any disagreement was resolved by discussion. Although quantitative data from most trials are presented, using relative risks or mean differences together with 95 per cent confidence intervals, trial heterogeneity and lack of outcome data prevented meaningful pooling of results from comparable trials. MAIN RESULTS Thirty-one trials, involving 1545 mainly young and male patients, met the inclusion criteria of the review. Methodological quality was highly variable: allocation concealment and / or assessor blinding were rare, and assessment of outcome was often incomplete and short-term. ACL injury and /or deficiency was the main focus of 18 trials, MCL injury of two trials, meniscal injury of nine trials and a mixture of soft-tissue injuries in the other two trials. The trial comparisons fell into five main categories: rehabilitation programme versus control (6 trials); one rehabilitation programme versus another (6 trials); different timing of rehabilitation (4 trials); one component of a programme versus another (6 trials); supplementary interventions to a programme versus none (9 trials). No trial provided sufficient evidence to establish the relative effectiveness of the intervention(s) under investigation. AUTHORS' CONCLUSIONS The available evidence for physiotherapist-led rehabilitation of ACL, MCL and meniscal injuries is wide ranging in terms of scope but insufficient to establish the relative effectiveness of the various approaches and methods in current use. There is a need for further research involving good quality, large scale randomised trials with sufficiently long follow-up to fully assess knee function and recovery.

Abstract
The control of mycobacterial infections is dependent on the finely tuned synergism between the innate and adaptive immune responses. The macrophage is the major host cell for Mycobacterium tuberculosis and the degree of virulence of mycobacteria may influence the initial macrophage response to infection. The cell wall molecule, phthiocerol dimycocerosate (DIM), is an important virulence factor that influences the early growth of M. tuberculosis in the lungs. To explore the basis for this effect we have compared the early gene response of human THP-1 macrophages to infection with virulent M. tuberculosis and the DIM-deficient DeltafadD26 M. tuberculosis strain using microarrays. Detailed analysis revealed a common core of macrophage genes, which were rapidly induced following infection with both strains, and deficiency of DIM had no significant effect on this initial macrophage transcriptional responses. In addition to chemokines and pro-inflammatory cytokines, the early response genes included components of the Toll-like receptor signalling, antigen presentation and apoptotic pathways, interferon response genes, cell surface receptors and their ligands, including TNF-related apoptosis inducing ligand (TRAIL) and CD40, and other novel genes. Therefore, although fadD26 deficiency is responsible for the early attenuation of the growth of M. tuberculosis in vivo, this effect is not associated with differences in the initial macrophage transcriptional response.

Abstract
UNLABELLED DESIGN/ SETTING: A cohort study of 1037 people born in Dunedin, New Zealand, in 1972 or 1973. PARTICIPANTS At assessment at age 32 years, 884 participants (432 women and 452 men; 87.1% of the surviving cohort) provided both sera and information on sexual behaviour. MAIN OUTCOME MEASURES The proportion of participants with antibodies to HSV-2 infection at ages 26 and 32 years was measured, and the incidence rates from first coitus to age 26 years and from age 26 to 32 years calculated, adjusting for the number of sexual partners and same-sex contact in these age periods. RESULTS At age 32 years, 14.6% of men and 22.5% of women had antibodies to HSV-2. The incidence rates for men and women from first coitus to age 26 years were, respectively, 6.5 and 14.3 per 1000 person-years. The incidence rates for men and women from age 26-32 years, respectively, were 14.3 and 15.8 per 1000 person-years. When adjusted for sexual behaviour, the incidence rate ratio, comparing the older with the younger age periods, was 2.9 (95% confidence interval (CI) 1.7 to 4.9) for men and 2.0 (1.2 to 3.4) for women. The adjusted incidence rate ratio when comparing women to men from first coitus to age 26 years was 2.5 (1.6 to 4.0), and from age 26-32 years was 1.3 (0.78 to 2.2). A test for interaction indicated that men and women had different patterns of incidence over time (p = 0.039). CONCLUSION In the general population, the risk of acquiring HSV-2 infection seems to increase with age at least to the early 30s, and differences in risk of acquisition for women compared with men become less with age. Health promotion and treatment to control HSV-2 infection should be aimed at all ages, not just at the young.

Abstract
Rheumatoid arthritis (RA) is associated with autoantibodies, the best known of which is rheumatoid factor (RF). RF/IgG complexes interact with FcgammaR on the surface of neutrophils, NK cells and monocyte/macrophages. We have analyzed the expression pattern and allelic polymorphisms of three FcgammaR genes (FcgammaRIIA, FcgammaRIIC and FcgammaRIIIA) in a large sample of RA patients and normal donors. We have found that the level of FcgammaR (CD16 and CD32) expression on NK cells is lower in RA patients than in normal individuals. Genotypic analysis demonstrated that the CD32 isoform expressed by the majority of RA patients was not the activating FcgammaRIIc1 isoform, commonly seen in normal individuals, but rather the inhibitory FcgammaRIIb isoform. The combination of the FcgammaRIIIA-176F allele with a lack of CD32 expression in NK cells appeared to be characteristic of RA subjects with aggressive disease. Since FcgammaRII and FcgammaRIIIA are predominantly expressed by NK cells, these data further suggest that FcgammaR-mediated activation of NK cells could be a disease-determining factor in RA patients.

Abstract
Genital herpes, caused by either herpes simplex virus type 1 or 2 (HSV-1 and HSV-2), is a significant public health problem worldwide. It increases the risk of infection with HIV, upregulates HIV after infection and can be associated with serious morbidity and mortality. It is now known that clinical and subclinical viral reactivation with resultant shedding from anogenital mucosa occurs frequently, resulting in transmission during sexual contact. Sexual transmission of HSV infection is common, even between monogamous individuals. Antiviral therapy reduces the frequency and degree of viral shedding and lowers the transmission rate in discordant monogamous couples, although transmission can still occur in people prescribed antiviral therapy. These encouraging data raise important questions for the management of genital HSV infection, particularly with regard to the prevention of transmission. Although the quantity of virus present is clearly important in transmission of some viruses, it is not clear whether this is the case for HSV transmission. Ideally, a surrogate marker needs to be able to identify individuals with detectable amounts of virus, and differentiate them from individuals with detectable amounts of virus that are transmissible. The aim of this supplement is to explore the issues surrounding the validation of surrogate markers of transmission of HSV, using examples from other human viral diseases, and to review the available evidence. In the future, exploration of these issues may shed light on management and prevention strategies. In particular, the results may clarify what evidence is required to warrant prescribing a drug for reducing HSV transmission, and for which patient populations this strategy is appropriate.

Abstract
Viral shedding of HSV occurs frequently in infected individuals. HSV is shed asymptomatically from multiple anatomical sites and shedding, like exposure, is a significant risk for transmission. However, the relationship between shedding frequency, viral titer and transmission is unknown. HSV-2 shedding is affected by the site and time since acquisition of infection. The advent of sensitive PCR techniques has shown that the magnitude and frequency of viral shedding is higher than shown previously with viral culture techniques. It has also clearly demonstrated that suppressive (daily) antiviral therapy reduces clinical and subclinical reactivation rates, and has been successfully used in the prevention of recurrent oral and genital HSV infections. A recent study has demonstrated that daily antiviral therapy with valaciclovir can significantly reduce transmission of HSV-2 between discordant heterosexual couples in monogamous relationships.

Abstract
A number of important risk factors for the acquisition of HSV-2 have been established including female gender, black or Hispanic ethnic origin, HIV infection, age, and increased number of sexual partners. Transmission is influenced by a number of biological factors such as sexual behavior, use of condoms, duration of relationships, and knowledge of a partner's serologic status. Vertical transmission (transmission of HSV from mother to neonate) is potentially life-threatening; neonatal HSV infection is associated with significant morbidity and mortality. The valaciclovir transmission study provides evidence that an antiviral agent can interrupt the transmission of a viral sexually transmitted disease between serologically discordant sexual partners. This review explores the importance of the cofactors that affect transmission, and makes recommendations on considerations for the prophylactic use of antiviral agents for the prevention of transmission in other patient populations.

Abstract
Surrogate markers are an important component in the process of investigating management and prevention strategies, and for increasing understanding of viral diseases. The importance of surrogate markers and applied statistical models is particularly true for HIV. For HIV infection, the development of such methods provides new approaches for evaluation of HIV therapies and vaccines, and for the study of HIV transmission and its pathogenesis. The complex natural history of hepatitis B infection demonstrates that viral load is not the only predictor of transmission of this virus; for hepatitis C infection, viral load per se is not a prognostic factor for disease progression, but cumulative viral load may affect the outcome, and therapy is aimed at eliminating active viral replication.

Abstract
Dendritic cells (DC) are critical for stimulation of naive T cells. Little is known about the effect of herpes simplex virus type 2 (HSV-2) infection on DC structure or function or if the observed effects of HSV-1 on human DC are reproduced in murine DC. Here, we demonstrate that by 12 h postinfection, wild-type (wt) HSV-2 (186) abortively infected murine bone marrow-derived DC and induced early cell death compared to UV-inactivated HSV-2 or mock-infected DC. HSV-2-induced loss of DC viability was more rapid than that induced by HSV-1 and was due, in part, to apoptosis, as shown by TEM, caspase-3 activation, and terminal deoxynucleotidyl transferase-mediated dCTP biotin nick end labeling. HSV induced type-specific changes in the murine DC immunophenotype. At 12 h postinfection, wt HSV-2 upregulated DC major histocompatibility complex (MHC) class II expression, and in contrast to UV-inactivated HSV-2, downregulated expression of MHC class I, but it had no effect on surface CD40, CD80, or CD86. Wt HSV-1 (MC-1) induced only CD40 upregulation. More-profound effects on the DC immunophenotype were observed in HSV-2-infected neonatal DC. Wt HSV of either serotype impaired murine DC-induced T-cell alloproliferation and lipopolysaccharide-induced DC interleukin-12 secretion. Thus, there are marked differences in the levels of HSV-induced cytolysis in DC according to the HSV serotype, although HSV-2 displays immunomodulatory effects on the DC immunophenotype and function similar to those of HSV-1.

Abstract
BACKGROUND First episode genital herpes simplex virus (HSV) infections can be classified into three groups, primary genital herpes (no previous exposure to HSV), non-primary first episode (IgG antibody to HSV of the non-presenting type), and first episode with pre-existing IgG HSV antibodies. The use of IgM to classify first episode genital herpes has not been evaluated. OBJECTIVE To evaluate the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of HSV-1 and HSV-2 IgM antibodies for the diagnosis of first episode genital herpes, when compared with clinical diagnosis. METHODS Patients with a first clinical episode of genital herpes were recruited. Sera were tested for IgG antibodies to HSV-2 using an indirect enzyme linked immunosorbent assay (ELISA). Equivocal results were resolved by western blot. HSV-1 IgG and IgM and HSV-2 IgM antibodies were detected using western blot. RESULTS 157 patients were recruited. 31 were excluded (missing data or no detectable antibodies and negative viral isolation). Therefore, 126 patients were included in the analysis. 23 (18.3%) had primary genital herpes, 34 (27.0%) non-primary first episode, and 69 (54.8%) had pre-existing genital herpes. The specificity and PPV of HSV IgM was 100%; the sensitivity was 79% and the NPV 85%. CONCLUSION IgM HSV serology may be useful in the management of some patients with first episode genital herpes and provide an indication of the source of infection. Drawbacks include the low sensitivity and NPV, lack of availability, IgM antibodies may occasionally be produced in response to recurrent infection and, finally, IgM antibodies may take up to 10 days to develop and last 7-10 days.

Abstract
Sexual behaviour is determined by social, cultural and personal factors. Sexual behaviour studies have been conducted in many countries. However, information from Australia is limited. This study was conducted in Obstetrics Department, Westmead Hospital, Sydney. Questionnaire-derived demographic and behavioural characteristics for public and private patients were compared using bivariate and logistic regression analyses. Of the patients, 3036 were public, and 595 private. On bivariate analysis some significant differences were private patients more likely to be born in Australia and have a higher education level whereas public patients were more likely to have had a greater number of lifetime sexual partners and younger age at first sex. Public patients were more likely to be herpes simplex virus type 2 (HSV-2) antibody positive (12%) than private patients (6%). On logistic regression significant variables included country of birth, being HSV-2 antibody positive, and age at first sex. A number of sexual and social variables were significantly different, comparing patients in the public and private sectors. Evaluation of interventions to reduce the sexual risk to women in the public sector should be considered, including encouraging young women to delay their sexual debut, and reducing the number of sexual partners.

Abstract
OBJECTIVES To determine if youth football officials responsible for dealing with injuries have appropriate first aid qualifications and knowledge? METHODS Information was collected from two youth football leagues by questionnaire. First aiders were asked to provide details of their qualifications and their response from a list of alternatives to an injury scenario. RESULTS Fifty two of 86 respondents did not have a current first aid qualification. Only 12% and 38% respectively gave the correct response to the injury scenarios "player choking" and "player unconscious". Health and injury records for the players were kept by 40% and 19% of teams. Written parental consent to emergency treatment was obtained by 30%. CONCLUSION This preliminary study shows an obligation on teams who do not possess a qualified first aider to evaluate their legal and moral responsibilities to their players. The Football Association and Health and Safety Executive should produce a list of recommended equipment, facilities, and first aid qualified personnel to which teams should have access at games and training sessions. Providers of first aid training should reassess their teaching of the management of the choking and unconscious casualty.

Abstract
The effect of mutations that truncate the WT1 protein on in vitro hematopoietic differentiation from embryonal stem cells has been examined by CFU-A assay, o-dianisidine staining for heme, and RT-PCR analysis of the expression of fetal and adult globins. In two independently isolated ES cell lines the mutations delay but do not abolish hematopoiesis. Analysis of replated CFU-A colonies indicates that the delay occurs prior to the formation of hematopoietic stem cells. The results demonstrate a role for WT1 at the onset of hematopoiesis.

Abstract
Video-based imaging systems for continuous (nonpulsed) x-ray fluoroscopy use a variety of video formats. Conventional video-camera systems may operate in either interlaced or progressive-scan modes, and CCD systems may operate in interline- or frame-transfer modes. A theoretical model of the image noise power spectrum corresponding to these formats is described. It is shown that with respect to frame-transfer or progressive-readout modes, interline or interlaced cameras operating in a frame-integration mode will result in a spectral shift of 25% of the total image noise power from low spatial frequencies to high. In a field-integration mode, noise power is doubled with most of the increase occurring at high spatial frequencies. The differences are due primarily to the effect of noise aliasing. In interline or interlaced formats, alternate lines are obtained with each video field resulting in a vertical sampling frequency for noise that is one half of the physical sampling frequency. The extent of noise aliasing is modified by differences in the statistical correlations between video fields in the different modes. The theoretical model is validated with experiments using an x-ray image intensifier and CCD-camera system. It is shown that different video modes affect the shape of the noise-power spectrum and therefore the detective quantum efficiency. While the effect on observer performance is not addressed, it is concluded that in order to minimize image noise at the critical mid-to-high spatial frequencies for a specified x-ray exposure, fluoroscopic systems should use only frame-transfer (CCD camera) or progressive-scan (conventional video) formats.

Abstract
BACKGROUND Soft-tissue injuries of the knee, mainly involving the anterior cruciate ligament (ACL), the medial collateral ligament (MCL) and menisci, are common and their rehabilitation after non-surgical or surgical treatment often involves intensive and prolonged physiotherapy. OBJECTIVES To examine the evidence for effectiveness of various physiotherapist-led (or 'directed') rehabilitation programmes, and of various interventions used within these programmes, for rehabilitation of acute or chronic ACL, MCL or meniscal injuries of the knee in adults. SEARCH STRATEGY We searched the Cochrane Musculoskeletal Injuries Group's specialised register (to June 2001), MEDLINE (from 1966 to August 1999), EMBASE (from 1980 to February 1997), CINAHL (1982 to April 1999), CURRENT CONTENTS (up to March 1999) and reference lists of relevant articles, and consulted colleagues. Date of the most recent search: June 2001. SELECTION CRITERIA Randomised or quasi-randomised clinical trials evaluating physiotherapist-led rehabilitation programmes, or components of rehabilitation programmes, for the treatment or post-surgical rehabilitation of ACL, MCL or knee meniscal injuries. Excluded were trials investigating electrical stimulation, or various interventions such as cryotherapy, immobilisation braces and continuous passive motion when used in initial or early treatment. Laboratory based trials reporting intermediate outcomes were also excluded. DATA COLLECTION AND ANALYSIS All trials, judged as fitting the selection criteria by two reviewers, were independently assessed by two reviewers for methodological quality by use of an 11 item checklist. Data were independently extracted by two reviewers. Any disagreement was resolved by discussion. Although quantitative data from most trials are presented, using relative risks or mean differences together with 95 per cent confidence intervals, trial heterogeneity and lack of outcome data prevented meaningful pooling of results from comparable trials. MAIN RESULTS Thirty-one trials, involving 1545 mainly young and male patients, met the inclusion criteria of the review. Methodological quality was highly variable: allocation concealment and / or assessor blinding were rare, and assessment of outcome was often incomplete and short-term. ACL injury and /or deficiency was the main focus of 18 trials, MCL injury of two trials, meniscal injury of nine trials and a mixture of soft-tissue injuries in the other two trials. The trial comparisons fell into five main categories: rehabilitation programme versus control (6 trials); one rehabilitation programme versus another (6 trials); different timing of rehabilitation (4 trials); one component of a programme versus another (6 trials); supplementary interventions to a programme versus none (9 trials). No trial provided sufficient evidence to establish the relative effectiveness of the intervention(s) under investigation. REVIEWER'S CONCLUSIONS The available evidence for physiotherapist-led rehabilitation of ACL, MCL and meniscal injuries is wide ranging in terms of scope but insufficient to establish the relative effectiveness of the various approaches and methods in current use. There is a need for further research involving good quality, large scale randomised trials with sufficiently long follow-up to fully assess knee function and recovery.
