Abstract
Observational studies have reported associations between nutrition during pregnancy and mental wellbeing. As secondary outcomes, the NiPPeR double-blind randomized trial in women planning conception investigated whether a myo-inositol, probiotics and enriched micronutrients formulation (intervention) taken preconception and throughout pregnancy could improve mental wellbeing during pregnancy and post-delivery, compared with a standard micronutrient supplement (control). Mood and anxiety symptoms were ascertained (Edinburgh Postnatal Depression Scale (EPDS), State-Trait Anxiety Inventory (STAI-state)) at preconception (baseline), 7, 28 and 34 weeks gestation, 3-weeks and 6-months post-delivery. EPDS>=13 was categorised as low mood; STAI-state>=45 as high anxiety. Change in mental health functioning was assessed as difference between preconception baseline and 6-month post-delivery 12-item Short-Form Health Survey (SF-12v2) mental component scores. Adjusting for site, ethnicity and baseline scores, there were no robust differences in EPDS and STAI-state scores between intervention and control groups across pregnancy (n = 630) and post-delivery (n = 532). Compared to controls, intervention group women averaged a 1.21 (95 %CI 0.04,2.39) higher change in SF-12v2 mental component score from preconception to 6-months post-delivery. Taking a myo-inositol, micronutrient and probiotic supplement during preconception/pregnancy had no effect on mood and anxiety, but there was evidence of a modest improvement in mental health functioning from preconception to 6-months post-delivery.

Abstract
BACKGROUND: The value, speed of completion and robustness of the evidence generated by TB treatment trials could be improved by implementing standards for best practice.METHODS: A global panel of experts participated in a Delphi process, using a 7-point Likert scale to score and revise draft standards until consensus was reached.RESULTS: Eleven standards were defined: Standard 1, high quality data on TB regimens are essential to inform clinical and programmatic management; Standard 2, the research questions addressed by TB trials should be relevant to affected communities, who should be included in all trial stages; Standard 3, trials should make every effort to be as inclusive as possible; Standard 4, the most efficient trial designs should be considered to improve the evidence base as quickly and cost effectively as possible, without compromising quality; Standard 5, trial governance should be in line with accepted good clinical practice; Standard 6, trials should investigate and report strategies that promote optimal engagement in care; Standard 7, where possible, TB trials should include pharmacokinetic and pharmacodynamic components; Standard 8, outcomes should include frequency of disease recurrence and post-treatment sequelae; Standard 9, TB trials should aim to harmonise key outcomes and data structures across studies; Standard 10, TB trials should include biobanking; Standard 11, treatment trials should invest in capacity strengthening of local trial and TB programme staff.CONCLUSION: These standards should improve the efficiency and effectiveness of evidence generation, as well as the translation of research into policy and practice.

Abstract
PURPOSE/OBJECTIVE(S) The Protocol-in-a-Day (PIAD) workshop was developed to support junior faculty and residents with clinical trial protocol design, with the main goal of providing initial feedback during development to reduce time for review and approval from institutional oversight committees. Our objectives are to mentor and educate participants and to evaluate the time to institutional approval by oversight committees. MATERIALS/METHODS PIAD provided concurrent educational feedback on 6 key elements of trial design. These included: (1) regulatory aspects; (2) institutional scientific review committee (SRC) and institutional review board (IRB); (3) clinical research and data coordination (including nursing); (4) statistics; (5) correlatives including imaging, biospecimens, and health services research/patient-reported outcomes; and (6) operations. The average number of days from submission to IRB approval or study activation for PIAD protocols was compared to other protocols submitted between January 2018 - January 2022 within the Division of Radiation Oncology. Participants were also given a 15-question survey to assess their perspective of the impact of the workshop. RESULTS A total of 25 protocols went through the PIAD workshop between January 2018-January 2022. Of the 25 protocols, 7 (28%) were excluded from this study due to not being submitted possibly after participants benefited from education on the limitations of their design. Eighteen protocols were included in our final analyses. These protocols included phase II (n = 11), phase 1 (n = 5), and phase III (n = 2). At the time of this report, all protocols (n = 18) have received IRB approval and have been activated. Protocol elements that could impact study activation included protocols requiring investigational new drug (IND) approval (n = 8) and multicenter studies (n = 1). Analyzing the time of submission to request for activation showed a decrease in time for protocols that went through PIAD vs those that did not [PIAD protocols, 254 days vs All other protocols, 262 days]. Likewise, those who attended PIAD had a lower average time from submission to IRB Approval [ PIAD protocols, 40 days vs All other protocols, 59 days]. All participants (100%) of the PIAD workshop responded that the educational program "improved the overall quality of the study design." The most commonly cited changes were protocol language (n = 17), statistics (n = 15), consent language (n = 8), and study design (n = 8). Aspects participants identified as the most educational included mentorship from regulatory, clinical research finance, and IRB review. CONCLUSION PIAD from participant surveys provided high educational value in the areas of improving trial quality, language and statistical design. When analyzing the average time, from 'submission to IRB initial approval' and 'submission to activation', PIAD protocols had a shorter time for approval, and thus suggests PIAD is effective in improving the overall design of protocols.

Abstract
Background Diet indices are widely used in nutritional research across communities but do not "capture" the full extent of diet variability across multiple countries. Empirically derived dietary patterns can provide additional information because they reflect combinations of foods potentially associated with health outcomes. Limited studies have evaluated preconception dietary patterns in heterogeneous populations. Objectives In the multisite Nutritional Intervention Preconception and During Pregnancy to Maintain Healthy Glucose Metabolism and Offspring Health (NiPPeR) study, the secondary aims included: 1) derive pooled and site-specific preconception dietary patterns, and 2) evaluate these patterns using anthropometric measures and metabolic biomarkers. Methods Women planning pregnancy (n = 1720) in the United Kingdom, Singapore, and New Zealand completed interviewer-administered harmonized FFQs and lifestyle questionnaires at recruitment. Across-cohort ("pooled") and site-specific dietary patterns were derived, and associations between dietary pattern scores and BMI, waist-to-hip ratio, plasma lipids, and glycemia assessed using multivariable linear regression, expressing results as SD change in outcome per SD change in dietary pattern score. Results The pooled analysis identified 3 dietary patterns: "Vegetables/Fruits/Nuts" ("Healthy"), "Fried potatoes/Processed meat/Sweetened beverages" ("Less Healthy"), and "Fish/Poultry/Noodles/Rice" ("Mixed"). The "Healthy" and "Less Healthy" pooled pattern scores were highly correlated with their corresponding site-specific dietary pattern scores ("Healthy": ρ = 0.87-0.93; "Less Healthy": ρ = 0.65-0.88). Women with higher scores for the "Healthy" pooled pattern had a lower waist-to-hip ratio (standardized β: -0.10; 95% CI: -0.18, -0.01); those with higher scores for the "Less Healthy" pooled pattern had a higher BMI (standardized β: 0.17; 95% CI: 0.09, 0.24), higher LDL cholesterol (standardized β: 0.10; 95% CI: 0.01, 0.19), and less optimal glucose profiles. However, we noted higher adherence to the "Healthy" pooled pattern with higher BMI. Conclusions The "Healthy" and "Less Healthy" pooled patterns were comparable to the corresponding site-specific patterns. Although the associations between these patterns and objective anthropometric/metabolic measures were largely in the expected directions, future studies are required to confirm these findings.This trial is registered at clinicaltrials.gov (NCT02509988).

Abstract
BACKGROUND: Data suggest that treatment with newer TB drugs (linezolid [LZD], bedaquiline [BDQ] and delamanid [DLM]), used in Khayelitsha, South Africa, since 2012, reduces mortality due to rifampicin-resistant TB (RR-TB).METHODS: This was a retrospective cohort study to assess 6-month mortality among RR-TB patients diagnosed between 2008 and 2019.RESULTS: By 6 months, 236/2,008 (12%) patients died; 12% (78/651) among those diagnosed in 2008-2011, and respectively 8% (49/619) and 15% (109/738) with and without LZD/BDQ/DLM in 2012-2019. Multivariable analysis showed a small, non-significant mortality reduction with LZD/BDQ/DLM use compared to the 2008-2011 period (aOR 0.79, 95% CI 0.5-1.2). Inpatient treatment initiation (aOR 3.2, 95% CI 2.4-4.4), fluoroquinolone (FQ) resistance (aOR 2.7, 95% CI 1.8-4.2) and female sex (aOR 1.5, 95% CI 1.1-2.0) were also associated with mortality. When restricted to 2012-2019, use of LZD/BDQ/DLM was associated with lower mortality (aOR 0.58, 95% CI 0.39-0.87).CONCLUSIONS: While LZD/BDQ/DLM reduced 6-month mortality between 2012 and 2019, there was no significant effect overall. These findings may be due to initially restricted LZD/BDQ/DLM use for those with high-level resistance or treatment failure. Additional contributors include increased treatment initiation among individuals who would have otherwise died before treatment due to universal drug susceptibility testing from 2012, an effect that also likely contributed to higher mortality among females (survival through to care-seeking).

Abstract
BACKGROUND Treatment of multidrug- and rifampin-resistant tuberculosis (MDR/RR-TB) is expensive, labour-intensive, and associated with substantial adverse events and poor outcomes. While most MDR/RR-TB patients do not receive treatment, many who do are treated for 18 months or more. A shorter all-oral regimen is currently recommended for only a sub-set of MDR/RR-TB. Its use is only conditionally recommended because of very low-quality evidence underpinning the recommendation. Novel combinations of newer and repurposed drugs bring hope in the fight against MDR/RR-TB, but their use has not been optimized in all-oral, shorter regimens. This has greatly limited their impact on the burden of disease. There is, therefore, dire need for high-quality evidence on the performance of new, shortened, injectable-sparing regimens for MDR-TB which can be adapted to individual patients and different settings. METHODS endTB is a phase III, pragmatic, multi-country, adaptive, randomized, controlled, parallel, open-label clinical trial evaluating the efficacy and safety of shorter treatment regimens containing new drugs for patients with fluoroquinolone-susceptible, rifampin-resistant tuberculosis. Study participants are randomized to either the control arm, based on the current standard of care for MDR/RR-TB, or to one of five 39-week multi-drug regimens containing newly approved and repurposed drugs. Study participation in all arms lasts at least 73 and up to 104 weeks post-randomization. Randomization is response-adapted using interim Bayesian analysis of efficacy endpoints. The primary objective is to assess whether the efficacy of experimental regimens at 73 weeks is non-inferior to that of the control. A sample size of 750 patients across 6 arms affords at least 80% power to detect the non-inferiority of at least 1 (and up to 3) experimental regimens, with a one-sided alpha of 0.025 and a non-inferiority margin of 12%, against the control in both modified intention-to-treat and per protocol populations. DISCUSSION The lack of a safe and effective regimen that can be used in all patients is a major obstacle to delivering appropriate treatment to all patients with active MDR/RR-TB. Identifying multiple shorter, safe, and effective regimens has the potential to greatly reduce the burden of this deadly disease worldwide.

Abstract
Rapid diagnostics, newer drugs, repurposed medications, and shorter regimens have radically altered the landscape for treating rifampicin-resistant TB (RR-TB) and multidrug-resistant TB (MDR-TB). There are multiple ongoing clinical trials aiming to build a robust evidence base to guide RR/MDR-TB treatment, and both observational studies and programmatic data have contributed to advancing the treatment field. In December 2019, the WHO issued their second 'Rapid Communication´ related to RR-TB management. This reiterated their prior recommendation that a majority of people with RR/MDR-TB receive all-oral treatment regimens, and now allow for specific shorter duration regimens to be used programmatically as well. Many TB programs need clinical advice as they seek to roll out such regimens in their specific setting. In this Perspective, we highlight our early experiences and lessons learned from working with National TB Programs, adult and pediatric clinicians and civil society, in optimizing treatment of RR/MDR-TB, using shorter, highly-effective, oral regimens for the majority of people with RR/MDR-TB.

Abstract
To improve the unsatisfactory treatment outcomes of multidrug-resistant TB (MDR-TB), it is essential we use new regimens based on newer drugs. To address challenges in the introduction of BDQ and the shorter treatment regimen (STR), the USAID has committed to support countries receiving
BDQ (through the USAID/Janssen Bedaquiline Donation Program), with targeted short-term technical assistance (TA). Six MDR-TB clinical consultants were recruited and provided TA to 17 countries between 2017 and 2019. Building on other in-country support, this short-term TA proved instrumental
in overcoming barriers, such as misconceptions about BDQ safety, inadequate clinical skills to manage patients and limited expansion plans to increase access to BDQ and the STR.

Abstract
Scabies is one of the most common disorders identified in any estimate of global skin disease prevalence. Furthermore, quantifying its impact on individuals and societies has been problematic. There has been a lack of clear case definitions and laboratory tests. There have been few epidemiological studies, particularly those focusing on low-income countries, variation in prevalence within high-income countries, or estimates of the effect of scabies on health beyond the skin, such as renal disease or mental wellbeing. Economic studies are also lacking. However, the new strategy of integrating surveillance for skin Neglected Tropical Diseases may well produce advancements on these issues, in addition to providing an overarching structure for health improvement and disease control.

Abstract
The drug-resistant tuberculosis (DR-TB) cascade-from estimated or incident cases to numbers successfully treated or disease-free survival-has long been characterised by sharp declines at each step in the cascade. The losses along the cascade vary across different settings, and the reasons why some countries have a higher burden of DR-TB are complex and multifactorial; broadly, weak health systems, inadequate financing and poverty all impact differential access to DR-TB care. Within a human rights framework that mandates the right to health and the right to benefit from scientific progress, the aim of this review is to focus on describing inequities in access to DR-TB care at critical points in the cascade.

Abstract
SUMMARYMultidrug-resistant (MDR) and extensively drug-resistant tuberculosis (XDR-TB) are global concerns, with stagnant treatment success rates of roughly 54% and 30%, respectively. Despite adverse events associated with several DR-TB drugs, newly developed drugs and shorter regimens are bringing hope; recent concern has focused on drugs that prolong the corrected QT interval (QTc). QTc prolongation is a risk factor for torsades de pointe (TdP), a potentially lethal cardiac arrhythmia. While QTc prolongation is used in research as a surrogate marker for drug safety, the correlation between QTc and TdP is not perfect and depends on additional risk factors. The electrocardiogram (ECG) monitoring that has been recommended when new drugs are used has created alarm among clinicians and National Tuberculosis Programmes (NTPs). ECG monitoring is often challenging in high-burden settings where treatment alternatives are limited. According to a review of studies, the prevalence of sudden death directly attributable to TdP by QTc-prolonging DR-TB drugs is likely less than 1%. The risk of death from an ineffective MDR-TB/XDR-TB regimen thus far exceeds the risk of death from arrhythmia. In patients with QTc prolongation who develop cardiac events, other significant risk factors in addition to the drugs themselves are nearly always present. Clinicians and NTPs should be aware of and manage all possible circumstances that may trigger an arrhythmia (hypopotassaemia and human immunodeficiency virus infection are probably the most frequent in DR-TB patients). We present the limited but growing evidence on QTc prolongation and DR-TB management and propose a clinical approach to achieve an optimal balance between access to life-saving drugs and patient safety.

Abstract
OBJECTIVE To assess the proportion of rifampicin-resistant tuberculosis (RR-TB) patients with potential earlier RR-TB diagnoses in Khayelitsha, South Africa. DESIGN We conducted a retrospective analysis among RR-TB patients diagnosed from 2012 to 2014. Patients were considered to have missed opportunities for earlier diagnosis if 1) they were incorrectly screened according to the Western Cape diagnostic algorithm; 2) the first specimen was not tested using Xpert® MTB/RIF; 3) no specimen was ever tested; or 4) the initial Xpert test showed a negative result, but no subsequent specimen was sent for follow-up testing in human immunodeficiency virus-positive patients. RESULTS Among 543 patients, 386 (71%) were diagnosed with Xpert and 112 (21%) had had at least one presentation at a health care facility within the 6 months before the presentation at which RR-TB was diagnosed. Overall, 95/543 (18%) patients were screened incorrectly at some point: 48 at diagnostic presentation only, 38 at previous presentation only, and 9 at both previous and diagnostic presentations. CONCLUSIONS These data show that a significant proportion of RR-TB patients might have been diagnosed earlier, and suggest that case detection could be improved if diagnostic algorithms were followed more closely. Further training and monitoring is required to ensure the greatest benefit from universal Xpert implementation.

Abstract
The World Health Organization uses a Grading of Recommendations Assessment, Development, and Evaluation process to make recommendations for treating multidrug-resistant tuberculosis. Even with this standardized approach, there have been discrepancies between recommendations for newer drugs such as bedaquiline and delamanid and the shorter regimen. This may be because newer drugs are novel chemical entities and may merit closer scrutiny. Here, we explore the problematic nature of this supposition, arguing that although the newer drugs have been used in fewer individuals, they may have more robust efficacy and safety data than many of the second-line drugs used in the shorter regimen.

Abstract
BACKGROUND While analysing trends in occupational mortality in England and Wales, we noticed an unexpectedly elevated proportion of deaths from multiple sclerosis (MS) among men in the armed forces. AIMS To document and explore possible explanations for the observed excess. METHODS We analysed data on underlying cause of death and last full-time occupation for 3,688,916 deaths among men aged 20-74 years in England and Wales during 1979-2010, calculating proportional mortality ratios (PMRs) standardised for age. We compared PMRs for MS in the armed forces with those for each main social class, and in selected other occupations. We also compared PMRs for MS with those for motor neurone disease (MND). RESULTS The overall PMR for MS in the armed forces during 1979-2010 was 243 (95%CI 203-288). The excess was apparent in each of three separate decades of study (PMRs, ranging from 220 to 259), and across the entire age range. PMRs for MS were not elevated to the same extent in comparator occupations, nor in any of the main social classes. There was no parallel increase in PMRs for MND. CONCLUSIONS These findings suggest that the high proportional mortality from MS in British military personnel is unlikely to have occurred by chance, or as an artefact of the method of investigation. However, the only military cohort study with published results on MS does not support an increased risk. It would be useful to analyse data on MS from other established military cohorts, to check for evidence of a hazard.

Results Compared with the 1012 men with gout, women with gout (n = 262) were older (71 vs. 61 years, p < 0.001) and had a greater burden of comorbid conditions (p < 0.001 for hypertension, diabetes, renal disease and obesity). Risk factors for gout differed with women more often taking diuretics (p < 0.001), while men more frequently had dietary triggers (p < 0.05). Conclusions The profiles of women and men with gout are markedly different, suggesting a need to tailor treatment recommendations.

Abstract
Objective To determine the duration of clinical benefit among patients with psoriatic arthritis (PsA) discontinuing tumour necrosis factor inhibitor (TNFi) therapy while in low disease activity (LDA), and to identify patient characteristics associated with prolonged clinical benefit. Methods We performed an observational cohort study assessing patients with PsA from the Consortium of Rheumatology Researchers of North America (CORRONA) registry who had discontinued TNFi after achieving LDA, defined as clinical disease activity index (CDAI) score ≤10 and physician's global assessment (PGA) of skin psoriasis ≤20/100. Kaplan–Meier method was used to estimate the duration of clinical benefit. Results Of the 5945 patients with PsA in CORRONA, 302 patients had discontinued TNFi (n=325) while in LDA and had follow-up data available. At time of discontinuation, mean PsA duration was 9.8 years, mean CDAI was 3.9, and mean duration of TNFi use was 1.5 years; 52.6% of patients had discontinued their first TNFi. Median time to loss of benefit was 29.2 months. 179 (55.1%) patients had persistent benefit at their previous clinic visit. An increased risk of losing clinical benefit was seen among patients with higher disease activity at discontinuation (CDAI≥3.2 vs <3.2; HR 1.43 (p=0.32)) and among smokers (HR 1.78 (p=0.027)). Conclusions Patients with PsA who achieve LDA may maintain clinical benefit after discontinuation of TNFi therapy.

Abstract
Multidrug-resistant tuberculosis (MDR-TB) is a serious public health problem, but the new drugs bedaquiline (BDQ) and delamanid offer hope to improve outcomes and minimise toxicity. In Khayelitsha, South Africa, patients are routinely started on BDQ in the out-patient setting. This report from the field describes BDQ use in the out-patient setting at the Nolungile Clinic. The clinic staff overall report a positive experience using the drug. Challenges have been based largely on the logistics of drug supply and delivery. BDQ can be started successfully in the out-patient setting, and can be a positive experience for both patients and providers. La tuberculose multirésistante (TB-MDR) est un problème de santé publique grave, mais les nouveaux médicaments que sont la bédaquiline (BDQ) et le délamanide apportent un espoir d'améliorer les résultats tout en réduisant la toxicité. A Khayelitsha, Afrique du Sud, les patients démarrent leur traitement par BDQ en consultation externe en routine. Ce rapport du terrain décrit l'utilisation de la BDQ à la consultation externe du dispensaire Nolungile. Dans l'ensemble, le personnel du centre de santé exprime une expérience positive du médicament. Les défis ont surtout été liés à la logistique de l'approvisionnement et de la distribution du médicament. La BDQ peut être mise en route avec succès dans le cadre d'une consultation externe et peut constituer une expérience positive pour les patients et les prestataires de soins. La tuberculosis multirresistente (TB-MDR) representa un grave problema de salud pública, pero la utilización de nuevos medicamentos como la bedaquilina (BDQ) y el delamanid ofrece perspectivas de mejores desenlaces terapéuticos y disminución de la toxicidad asociada. En Khayelitsha, Suráfrica, se inicia de manera sistemática el tratamiento ambulatorio con BDQ. En el presente informe del terreno, se describe la utilización de BDQ en tratamiento antituberculoso ambulatorio en el centro de atención Nolungile. En general, los miembros del personal del centro refirieron una experiencia positiva con la administración del medicamento. Las dificultades surgieron en gran parte con respecto a aspectos logísticos del suministro y la administración del medicamento. Es posible iniciar un tratamiento eficaz con BDQ en condiciones ambulatorias, y represente una experiencia positiva para los pacientes y los profesionales de salud.

Abstract
BACKGROUND The World Health Organization recommends tuberculin skin tests (TSTs) where feasible to identify individuals most likely to benefit from isoniazid preventive therapy (IPT). The requirement for TST reading after 48-72 h by a trained nurse is a barrier to implementation and increases loss to follow-up. METHODS Patients with human immunodeficiency virus (HIV) infection were recruited from a primary care clinic in South Africa and trained by a lay counsellor to interpret their own TST. The TST was placed by a nurse, and the patient was asked to return 2 days later with their self-reading result, followed by blinded reading by a trained nurse (reference). RESULTS Of 227 patients, 210 returned for TST reading; 78% interpreted their test correctly: those interpreting it as negative were more likely to be correct (negative predictive value 93%) than those interpreting it as positive (positive predictive value 42%); 10/36 (28%) positive TST results were read as negative by the patient. CONCLUSIONS Patients with HIV in low-resource settings can be trained to interpret their own TST. Those interpreting it as positive should return to the clinic within 48-72 h for confirmatory reading and IPT initiation; those with a negative interpretation can return at their next scheduled visit and initiate IPT at that time if appropriate.

Abstract
OBJECTIVES To monitor the impact of health and safety provisions and inform future preventive strategies, we investigated trends in mortality from established occupational hazards in England and Wales. METHODS We analysed data from death certificates on underlying cause of death and last full-time occupation for 3 688 916 deaths among men aged 20-74 years in England and Wales during 1979-2010 (excluding 1981 when records were incomplete). Proportional mortality ratios (PMRs), standardised for age and social class, were calculated for occupations at risk of specified hazards. Observed and expected numbers of deaths for each hazard were summed across occupations, and the differences summarised as average annual excesses. RESULTS Excess mortality declined substantially for most hazards. For example, the annual excess of deaths from chronic bronchitis and emphysema fell from 170.7 during 1979-1990 to 36.0 in 2001-2010, and that for deaths from injury and poisoning from 237.0 to 87.5. In many cases, the improvements were associated with falling PMRs (suggesting safer working practices), but they also reflected reductions in the numbers of men employed in more hazardous jobs, and declining mortality from some diseases across the whole population. Notable exceptions to the general improvement were diseases caused by asbestos, especially in some construction trades and sinonasal cancer in woodworkers. CONCLUSIONS The highest priority for future prevention of work-related fatalities is the minority of occupational disorders for which excess mortality remains static or is increasing, in particular asbestos-related disease among certain occupations in the construction industry and sinonasal cancer in woodworkers.

Abstract
BackgroundThere is increasing interest in discontinuing biological therapies for patients with rheumatoid arthritis (RA) achieving good clinical responses, provided patients maintain clinical benefit.MethodsWe assessed patients with RA from the Corrona registry who discontinued treatment with their first tumour necrosis factor inhibitor (TNFi) while in low-disease activity (LDA) or lower levels of disease activity. Patients were followed until they lost clinical benefit, defined as increased disease activity or change in RA medications. Duration of maintenance of clinical benefit was estimated using the Kaplan–Meier method. Cox proportional hazard models were assessed to identify factors related to maintenance of benefit.ResultsWe identified 717 eligible patients with RA from 35 656 in the Corrona registry. At discontinuation, patients had a median RA duration of 8 years, mean clinical disease activity score of 4.3±0.11; 41.8% were using TNFi as monotherapy. 73.4% of patients maintained benefit for >12 months after discontinuing therapy and 42.2% did so through 24 months. Factors predictive of maintaining clinical benefit in multivariate analysis included lower disease activity, less pain and better functional status at the time of TNFi discontinuation. Among 301 patients initiating their first TNFi within the registry, faster responders (ie, those who achieved LDA in 4 months or less) did better than slower responders (HR 1.54 (95% CI 1.17 to 2.04)). RA disease duration did not affect maintenance of clinical benefit.ConclusionsDiscontinuation of a first course of TNFi may be associated with persistent clinical benefit. Half of patients maintained response through 20 months. Several patient characteristics may help predict persistent benefit.

Abstract
BACKGROUND It is unclear whether and to what extent intensive case management is more effective than standard occupational health services in reducing sickness absence in the health care sector. AIMS To evaluate a new return to work service at an English hospital trust. METHODS The new service entailed intensive case management for staff who had been absent sick for longer than 4 weeks, aiming to restore function through a goal-directed and enabling approach based on a bio-psycho-social model. Assessment of the intervention was by controlled before and after comparison with a neighbouring hospital trust at which there were no major changes in the management of sickness absence. Data on outcome measures were abstracted from electronic databases held by the two trusts. RESULTS At the intervention trust, the proportion of 4-week absences that continued beyond 8 weeks fell from 51.7% in 2008 to 49.1% in 2009 and 45.9% in 2010. The reduction from 2008 to 2010 contrasted with an increase at the control trust from 51.2% to 56.1%-a difference in change of 10.7% (95% CI 1.5-20.0%). There was also a differential improvement in mean days of absence beyond 4 weeks, but this was not statistically significant (1.6 days per absence; 95% CI -7.2 to 10.3 days). CONCLUSIONS Our findings suggest that the intervention was effective, and calculations based on an annual running cost of £57 000 suggest that it was also cost-effective. A similar intervention should now be evaluated at a larger number of hospital trusts.

Abstract
OBJECTIVE This study tested a pathway whereby acupuncturists' communication of optimism for treatment effectiveness would enhance patients' satisfaction during treatment, which in turn would contribute to better pain and function outcomes for patients with osteoarthritis of the knee. METHODS Secondary analysis from a 2 arm (real vs. sham acupuncture, high vs. neutral expectations) RCT. 311 patients with knee osteoarthritis received acupuncture over 10-12 sessions. Coders rated the degree to which acupuncturists communicated optimism for the treatment's effectiveness. Satisfaction with acupuncture was assessed 4 weeks into treatment. Pain and function were assessed 6 weeks following treatment. RESULTS Patients experiencing better outcomes were more satisfied with acupuncture during treatment, were younger, and had better baseline pain and function scores. Satisfaction during treatment was greater when patients interacted with more optimistic clinicians and had higher pretreatment expectations for acupuncture efficacy. CONCLUSION Acupuncturists' communication of optimism about treatment effectiveness contributed to pain and function outcomes indirectly through its effect on satisfaction during treatment. Future research should model pathways through which clinician-patient communication affects mediating variables that in turn lead to improved health outcomes. PRACTICAL IMPLICATIONS While clinicians should not mislead patients, communicating hope and optimism for treatment effectiveness has therapeutic value for patients.

Abstract
OBJECTIVE The primary aim of this study was to determine the impact of obesity in predicting short and long-term pain relief and functional recovery in total joint arthroplasty (TJA) either as an independent risk factor or a factor mediated by two chronic conditions associated with obesity-cardiac disease and diabetes mellitus. METHOD A prospective observational study of 520 patients with primary joint arthroplasties. Pain and functional outcomes were evaluated with the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index within a month of surgery and then 6 months and 3 years post-operatively. Obesity, cardiac disease and diabetes mellitus were examined as potential risk factors for poor recovery. Patients were classified into four groups based on body mass index (BMI): (normal<25.0 kg/m(2); overweight 25.0-29.9 kg/m(2); obese Class 1 30.0-34.9 kg/m(2); severe obese Class 2&3 35.0 ≥ kg/m(2)). Linear mixed models for each joint type (hip and knee arthroplasty) were developed to examine the pattern of recovery and the effect of obesity. RESULTS Ninety-nine (19%) patients were severely obese, 127 (24%) had cardiac disease and 58 (11%) had diabetes mellitus. Baseline pain and functional scores were similar regardless of BMI classification. Severe obesity was a significant risk factor for worse pain and functional recovery at 6 months but no longer at 3 years following total hip and knee arthroplasty. Cardiac disease predicted a slower recovery after hip arthroplasty. No significant interactions existed between obesity and cardiac disease or diabetes mellitus. DISCUSSION Severe obesity is an independent risk factor for slow recovery over 3 years for both hip and knee arthroplasties.

METHODS A total of 208 patients participated in the study (mean age 63 years, 68% female, and 66% white). Participants were randomized to 1 of 3 groups: 1) educational booklet on OA management (control), 2) patient decision aid (videobooklet) on OA management, and 3) patient decision aid (videobooklet) + adaptive conjoint analysis (ACA) tool. The ACA tool enables patients to consider competing attributes (i.e., specific risks/benefits) by asking them to rate a series of paired comparisons. The primary outcome was the decisional conflict scale ranging from 0-100. Differences between groups were analyzed using analysis of variance and Tukey's honestly significant difference tests. RESULTS Overall, decisional conflict decreased significantly in all groups (P < 0.05). The largest reduction in decisional conflict was observed for participants in the videobooklet decision aid group (21 points). Statistically significant differences in pre- versus postintervention total scores favored the videobooklet group compared to the control group (21 versus 10) and to the videobooklet plus ACA group (21 versus 14; P < 0.001). Changes in the decisional conflict score for the control group compared to the videobooklet decision aid + ACA group were not significantly different. CONCLUSION In our study, an audiovisual patient decision aid decreased decisional conflict more than printed material alone or the addition of a more complex computer-based ACA tool requiring more intense cognitive involvement and explicit value choices.

Abstract
OBJECTIVE There is conflicting evidence on the efficacy of traditional Chinese acupuncture (TCA), and the role of placebo effects elicited by acupuncturists' behavior has not been elucidated. We conducted a 3-month randomized clinical trial in patients with knee osteoarthritis to compare the efficacy of TCA with sham acupuncture and to examine the effects of acupuncturists' communication styles. METHODS Acupuncturists were trained to interact in 1 of 2 communication styles: high or neutral expectations. Patients were randomized to 1 of 3 style groups, waiting list, high, or neutral, and nested within style, TCA or sham acupuncture twice a week over 6 weeks. Sham acupuncture was performed in nonmeridian points with shallow needles and minimal stimulation. Primary outcome measures were Joint-Specific Multidimensional Assessment of Pain (J-MAP), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and satisfaction scores. RESULTS Patients (n = 455) received treatment (TCA or sham) and 72 controls were included. No statistically significant differences were observed between TCA or sham acupuncture, but both groups had significant reductions in J-MAP (-1.1, -1.0, and -0.1, respectively; P < 0.001) and WOMAC pain (-13.7, -14, and -1.7, respectively; P < 0.001) compared with the waiting group. Statistically significant differences were observed in J-MAP pain reduction and satisfaction, favoring the high expectations group. In the TCA and sham groups, 52% and 43%, respectively, thought they had received TCA (κ = 0.05), suggesting successful blinding. CONCLUSION TCA was not superior to sham acupuncture. However, acupuncturists' styles had significant effects on pain reduction and satisfaction, suggesting that the analgesic benefits of acupuncture can be partially mediated through placebo effects related to the acupuncturist's behavior.

Abstract
OBJECTIVE To examine whether communication factors affect health care provider and patient agreement on the need for, risks of, and benefits of joint replacement, and also whether degree of agreement predicts patient satisfaction and intent to follow treatment recommendations. METHODS Health care providers (n = 27) and patients (n = 74) with severe osteoarthritis (OA) were recruited from clinics in Houston, Texas. Patients completed a baseline survey prior to the consultation. After the visit, patients and providers completed measures of the severity of the patient's OA, the expected benefits of total knee replacement (TKR), and concern about surgical complications. Patients also completed satisfaction and intent to adhere measures. Provider communication and patient participation were measured by patient self-report and by observers' codings of audiorecordings of the consultations. RESULTS Provider-patient agreement was modest to poor regarding severity of the patient's OA and the expected benefits and risks of TKR. Providers and patients were more aligned on the patient's OA severity when providers used more partnership building but spent less time simply giving information. Differences between providers' and patients' concerns about surgery were greater when patients were less participatory, African American, or expressed lower trust in their doctors. Patient satisfaction and intent to adhere were predicted by provider-patient agreement on the benefits of TKR. CONCLUSION Patients and providers often differ in their beliefs about the need for, risks of, and benefits of TKR, and these differences can affect patient satisfaction and commitment to treatment. Facilitating active patient participation might contribute to greater physician-patient agreement on the patient's concerns about OA and surgical interventions.

Abstract
OBJECTIVE To evaluate the quality of reviews about etanercept (ETN) and infliximab (IFX), two biologic treatments for rheumatoid arthritis (RA). STUDY DESIGN A comprehensive, systematic review, including searches of MEDLINE, EMBASE, and other electronic databases and hand-searches for published and unpublished literature. Two raters independently examined each article and identified systematic reviews as those including either a description of: (1) sources for identification and data retrieval; or (2) search strategy. They applied the quality of reporting of meta-analyses (QUOROM) instrument to systematic reviews. RESULTS Of 3,620 total citations, 281 were identified as reviews. Of these, 26 (9%) qualified as systematic rather than narrative. Overall, few reviews described selection of sources, critical appraisal, or quantitative summary or synthesis. Systematic reviews most often failed to explain validity assessment. Several articles did not disclose authors' participation in industry-funded clinical trials. Most reviews published in high impact factor and rheumatology journals did not meet many quality standards. Significant associations existed between review type (narrative vs. systematic) and reported funding (P=0.05), conflicts of interest (P=0.005), and country of publication (P<0.0001). CONCLUSION More than 90% of the published reviews were narrative and did not report methods and conflicts of interest in sufficient detail, raising concerns about selection and reporting bias.

Abstract
High quality coding of hospital activity is important because the data is used for resource allocation and measuring performance. There is little information on the quality of coding of admissions of frail older people who have multiple diagnoses, co-morbidities and functional impairment. Presence or absence of four geriatric syndromes and eight medical conditions was noted on case note review (CNR). Discharge summaries (DS) and hospital coding (HC) were reviewed and compared with the CNR. Forty patients had at least one geriatric syndrome noted in the DS; 16 (40.0%) were captured by the HC. Of 57 patients with at least one medical condition noted in the DS, 52 (91.2%) were captured by the HC (p<0.0001 for difference in HC capture rates). We have demonstrated poor capture of information on geriatric syndromes compared to medical conditions in discharge summaries and hospital coding and propose a problem list bookmark approach to improve this.

Abstract
PURPOSE To evaluate the effects of social support on comprehension and recall of consent form information in a study of Parkinson disease patients and their caregivers. DESIGN AND METHODS Comparison of comprehension and recall outcomes among participants who read and signed the consent form accompanied by a family member/friend versus those of participants who read and signed the consent form unaccompanied. Comprehension and recall of consent form information were measured at one week and one month respectively, using Part A of the Quality of Informed Consent Questionnaire (QuIC). RESULTS The mean age of the sample of 143 participants was 71 years (SD = 8.6 years). Analysis of covariance was used to compare QuIC scores between the intervention group (n = 70) and control group (n = 73). In the 1-week model, no statistically significant intervention effect was found (p = 0.860). However, the intervention status by patient status interaction was statistically significant (p = 0.012). In the 1-month model, no statistically significant intervention effect was found (p = 0.480). Again, however, the intervention status by patient status interaction was statistically significant (p = 0.040). At both time periods, intervention group patients scored higher (better) on the QuIC than did intervention group caregivers, and control group patients scored lower (worse) on the QuIC than did control group caregivers. IMPLICATIONS Social support played a significant role in enhancing comprehension and recall of consent form information among patients.
