Abstract
BACKGROUND Chronic respiratory diseases (CRDs) may cause reduced oxygen availability to organs and body tissues, leading to an increased risk for ischemic damage, which can result in brain tissue injury. This damage can lead to a myriad of neurological symptoms contributing to cognitive decline. Cognitive interventions may attenuate cognitive deficits in people with CRDs; however, the effects have not yet been systematically summarized in the literature. OBJECTIVE The purpose of this systematic review is to assess the effects of cognitive interventions (including cognitive behavioral therapy and transcranial brain stimulation) on cognitive function (primary outcome), HRQL, self-management, symptoms, physical activity, physical function, ability to complete activities of daily living (ADLs), hospital admissions, functional capacity, functional performance, psychological and social outcomes, exacerbations, healthcare utilization, and survival in individuals with CRDs. METHODS This review will be conducted in accordance with the Cochrane handbook for systematic reviews of interventions and reported following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Searches will be performed in MEDLINE, Embase, Emcare, PsycINFO, Scopus, and CINAHL. Articles will be included if they focus on the effects of cognitive interventions on adults with CRDs, are published in peer-reviewed journals, and are written in English, French, or Portuguese. Risk of bias will be evaluated with the Cochrane Risk of Bias 2 tool for randomized controlled trials, and the Risk of Bias in Non-randomized Studies of Interventions tool for nonrandomized studies. Meta-analyses will be performed if at least 2 studies provided sufficient data for a specific outcome. The GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) assessment will be used to evaluate the overall quality of the evidence. RESULTS This systematic review was initiated in November 2022 and registered with PROSPERO in February 2023, prior to title and abstract screening. Full-text screening of articles will be completed in June 2023. Data extraction and drafting of the manuscript will occur from July 2023 to August 2023, with expected publication in February 2024. CONCLUSIONS This systematic review will summarize the effects of cognitive interventions on cognitive function in people with CRDs. It will guide health care professionals in selecting evidence-based strategies to enhance cognitive well-being and overall health outcomes for individuals with CRDs. Additionally, it will identify research gaps and highlight areas for future exploration, supporting researchers in advancing knowledge in this field.

Abstract
AIMS The World Health Organization (WHO)'s Mental Health Atlas series has established itself as the single most comprehensive and most widely used source of information on the global mental health situation. The data derived from the latest Mental Health Atlas survey carried out in 2014 describes the availability and delivery of mental health services in the WHO's Member States, focussing on differences by country's income level. METHODS The data contained in this paper are mainly derived from questions relating to mental health service availability and uptake, as well as on financial and human resources for mental health. Results are presented as median values and analysed by World Bank income group. Interquartile ranges are also provided as measures of statistical dispersion. RESULTS In total, 171 out of WHO's 194 Member States were able to at least partially complete the Atlas questionnaire. The results highlight a wide gap between high and low-medium income countries in a number of areas: for example, high-income countries have 20 times more beds in community-based inpatient units and 30 times more admissions; the rate of patients cared by outpatient facilities is 40 times higher; and there are 66 times more community outpatient contacts and 15 times more mental health staff at outpatient level. Overall resources for mental health are not distributed efficiently: globally about 60% of financial resources and over two-thirds of all available mental health staff are concentrated in mental hospitals, which serve only a small proportion of patients. Results indicate that outpatient care is the only effective means of increasing the coverage for mental disorders and is expanding, but it is strongly influenced by country income level. Two elements of the network of mental health facilities are particularly scarce in low- and middle-income countries: day treatment facilities and community residential facilities. CONCLUSIONS The WHO Mental Health Atlas 2014 survey provides basic mental health information at the level of WHO's Member States, concerning mental health resources and activities. Atlas promotes the use of information, usually underestimated not only in low- and middle-income countries but also in high-income countries. Information is needed not only for monitoring the scaling up of the mental health system at country level, but also for improving transparency and accountability for users, families and the public.

Abstract
Structure-based pharmacophores were generated and validated using the bioactive conformations of different co-crystallized enzyme-inhibitor complexes for allosteric palm-1 and thumb-2 inhibitors of NS5B. Two pharmacophore models were obtained, one for palm-1 inhibitors with sensitivity = 0.929 and specificity = 0.983, and the other for thumb-2 inhibitors with sensitivity = 1 and specificity = 0.979. In addition, a quantitative structure activity relationship (QSAR) models were developed based on using the values of different scoring functions as descriptors predicting the activity on both allosteric binding sites (palm-1 and thumb-2). QSAR studies revealed good predictive and statistically significant two descriptor models (r2 = .837, r2adjusted = .792 and r2prediction = .688 for palm-1 model and r2 = .927, r2adjusted = .908 and r2prediction = .779 for thumb-2 model). External validation for the QSAR models assured their prediction power with r2ext = .72 and .89 for palm-1 and thumb-2, respectively. Different docking protocols were examined for their validity to predict the correct binding poses of inhibitors inside their respective binding sites. Virtual screening was carried out on ZINC database using the generated pharmacophores, the selected valid docking algorithms and QSAR models to find compounds that could theoretically bind to both sites simultaneously.

Abstract
INTRODUCTION Tobacco smoking, a habitual behavior, is addictive and detrimental to health. Quitting requires personal abilities and environmental opportunities and therefore, improving these abilities and opportunities will undoubtedly act on smokers' motivation to quit. METHODS A prospective single-blinded randomized controlled interventional study was conducted among first year undergraduate students in Malaysia. A total of eighty smokers were randomly allocated to a control or intervention groups (40/40). Randomization remained concealed from research personnel. All participants were followed up for six months to evaluate abstinence. RESULTS Quit line enrolment rate of the intervention group was 55% (22) compared to 7.5% (3) in the control (P < 0.001 95% CI 30.1 - 64.9). In the intervention group 27% (6) sustained quitting for six months compared to none in the control group. CONCLUSION This study has shown that brief advice for smoking cessation is more effective than an information leaflet alone to promote quitting and that to maintain abstinence quit line follow up is necessary. Larger samples size and longer follow up studies are needed to further confirm these findings.

Abstract
Armed conflicts and natural disasters impact negatively on the mental health and well-being of affected populations in the short- and long-term and affect the care of people with pre-existing mental health conditions. This paper outlines specific actions for mental health and psychosocial support by the health sector in the preparedness, response and recovery phases of emergencies. Broad recommendations for ministries of health are to: (1) embed mental health and psychosocial support in national health and emergency preparedness plans; (2) put in place national guidelines, standards and supporting tools for the provision of mental health and psychosocial support during emergencies; (3) strengthen the capacity of health professionals to identify and manage priority mental disorders during emergencies; and (4) utilize opportunities generated by the emergency response to contribute to development of sustainable mental health-care services.

Abstract
OBJECTIVE There is evidence for an association between levels of urinary C-telopeptide fragments of type II collagen (uCTX-II) and risk of knee osteoarthritis (OA). The aim of this cohort study was to examine the association between uCTX-II levels and knee cartilage and bone changes in middle-aged women without clinical knee disease. DESIGN 140 women, aged 40-67 years, with no significant knee pain, knee injury or any forms of arthritis, underwent knee magnetic resonance imaging (MRI) at baseline and 2 years later. Cartilage volume, cartilage defects, tibial plateau bone area and bone marrow lesions (BMLs) were measured using validated methods. Baseline uCTX-II was measured using enzyme-linked immunosorbent assay (ELISA). RESULTS For every one unit (natural logarithm transformed) increase in baseline uCTX-II level, there was an increase in the prevalence of medial tibiofemoral cartilage defects (Odds ratio (OR) 4.36, 95% confidence interval (CI) 1.58-12.04), medial (80.2 mm(2), 95% CI 9.3-151.1) and lateral (86.0 mm(2), 95% CI 33.3-138.7) tibial plateau bone area, and the prevalence of lateral tibiofemoral BMLs (OR 10.62, 95% CI 1.82-61.85). Baseline uCTX-II levels were not significantly associated with baseline tibial cartilage volume or changes in knee cartilage volume or defects or bone area over 2 years, although there was a trend for the deterioration of medial tibiofemoral BMLs (P = 0.06). CONCLUSION In middle-aged women without clinical knee disease, higher uCTX-II levels were associated with early detrimental structural changes at the knee (cartilage defects, tibial bone expansion and BMLs) at baseline but not over 2 years. Further work will be needed to determine its sensitivity to change and whether it predicts disease progression over longer time periods.

Abstract
UNLABELLED Although socioeconomic status (SES) is inversely related to most diseases, this systematic review showed a paucity of good quality data examining influences of SES on osteoporotic fracture to confirm this relationship. Further research is required to elucidate the issue and any underlying mechanisms as a necessary precursor to considering intervention implications. INTRODUCTION The association between socioeconomic status (SES) and musculoskeletal disease is little understood, despite there being an inverse relationship between SES and most causes of morbidity. We evaluated evidence of SES as a risk factor for osteoporotic fracture in population-based adults. METHODS Computer-aided search of Medline, EMBASE, CINAHL, and PsychINFO from January 1966 until November 2007 was conducted. Identified studies investigated the relationship between SES parameters of income, education, occupation, type of residence and marital status, and occurrence of osteoporotic fracture. A best-evidence synthesis was used to summarize the results. RESULTS Eleven studies were identified for inclusion, which suggested a lack of literature in the field. Best evidence analysis identified strong evidence for an association between being married/living with someone and reduced risk of osteoporotic fracture. Limited evidence exists of the relationship between occupation type or employment status and fracture, or for type of residence and fracture. Conflicting evidence exists for the relationship between osteoporotic fracture and level of income and education. CONCLUSION Limited good quality evidence exists of the role SES might play in osteoporotic fracture. Further research is required to identify whether a relationship exists, and to elucidate underlying mechanisms, as a necessary precursor to considering intervention implications.

Abstract
OBJECTIVES Although cartilage loss occurs with advancing age and is a hallmark of OA, the factors that affect cartilage change are not well established. The aim of this study was to explore the determinants of change in patella cartilage volume over 2 yrs among healthy middle-aged women with no clinical knee OA. METHODS One hundred and forty-eight women with no clinical knee OA were recruited from a previous population-based cross-sectional study of healthy women aged 40-67 yrs. MRI was performed at baseline and at 2 yrs, to assess patella cartilage and bone volume. Self-reported exercise was assessed by questionnaire. RESULTS Annual loss of patella cartilage volume was 1.6% (95% CI 1.2, 1.9). Age was positively associated with patella cartilage volume loss after adjustment for confounders (P = 0.05). For every 1 mm(3) increase in patella bone volume at baseline, annual cartilage loss was reduced by 8.05 mm(3) (95% CI 12.91, 3.19; P < 0.001). Fortnightly participation in exercise promoting an increased heart and respiratory rate for at least 20 min also tended to be associated with a reduced rate of patella cartilage volume loss (P = 0.09). CONCLUSION Among middle-aged women with no clinical knee OA, advancing age expedites the rate of patella cartilage volume loss, while increased patella bone volume and exercise participation tends to be associated with a reduction in the rate of patella cartilage volume loss. Interventions targeting modifiable factors, such as physical activity, warrant further investigation as they may help to prevent patellofemoral OA.

Abstract
OBJECTIVE Bone marrow lesions (BML) are important in established knee osteoarthritis, predicting pain and progression of disease. Whether BML are also associated with longitudinal changes in knee structure in an asymptomatic population is unknown. METHODS 148 healthy pain-free women in middle age with no history of knee injury or clinical knee osteoarthritis who had a magnetic resonance imaging (MRI) scan performed on their dominant knee at baseline, had another MRI 2 years later to assess whether having a BML present at baseline affected change in tibiofemoral cartilage defects and tibial cartilage volume. RESULTS BML were present in 14.9% of women at baseline. The risk of progression of total tibiofemoral cartilage defects was significantly higher when a very large BML was present (odds ratio 5.55, 95% CI 1.04 to 29.6) compared with when no BML was present, after adjusting for potential confounders. In the lateral compartment, the rate of cartilage volume loss was significantly greater when a BML was present after adjusting for confounders (regression coefficient 39.2 mm(3), 95% CI 11.1 to 67.2, p = 0.007). CONCLUSIONS In healthy women without pain at baseline, large BML were associated with both progression of cartilage defects in the whole tibiofemoral joint and more rapid lateral tibial cartilage loss. These data suggest that the relationship between BML and knee cartilage in healthy women is similar to that described in established osteoarthritis. It is possible that BML may predict an increased risk of knee osteoarthritis and facilitate the identification of novel interventions to prevent disease.

Abstract
OBJECTIVE Bone marrow lesions (BMLs) have been shown to be associated with pain and progression of knee osteoarthritis (OA) in those with disease. The natural history of BMLs in a healthy population and their role in the pathogenesis of OA are unknown. The aim of this study was to determine the risk factors for BMLs in healthy subjects and the association of BMLs with knee structure. METHODS One hundred and seventy-six healthy, adult women with no history of knee injury, or clinical knee OA had magnetic resonance imaging performed on their dominant knee to assess BMLs, tibiofemoral cartilage defects, tibial cartilage volume and bone area. RESULTS Thirteen percent of subjects had knee BMLs. The prevalence was higher in the medial tibiofemoral compartment. There was a significant positive association between BMLs and cartilage defects after adjusting for the potential risk factors: age, height, weight and cartilage volume [odds ratio (OR) 1.78 (95% confidence interval [CI] 1.12, 2.82), P=0.01]. BML was positively associated with tibial plateau bone area in the lateral compartment [OR 1.67 (95% CI 1.02, 2.71), P=0.04]. There was no significant association between BMLs and cartilage volume. Independent risk factors for BMLs after adjustment were increasing height [OR 1.18 (95% CI 1.02, 1.36), P=0.02 for lateral compartment] and weight [OR 1.04 (95% CI 1.01, 1.08), P=0.005 for total knee]. CONCLUSION These data support that BMLs are present in a similar distribution to tibiofemoral knee OA. Their presence is associated with risk factors (height and weight) for knee OA, and the early structural changes of knee OA in subjects without knee pain and thus no clinical disease. Longitudinal studies will clarify whether BMLs relate to the pathogenesis of clinical knee OA.

Abstract
OBJECTIVES Although the geometry of the trochlear groove is considered important in the pathogenesis of patellofemoral joint pathology it is unclear how the shape of the trochlear groove relates to patella morphology. This cross-sectional study investigated the relationship between the shape of the trochlear groove and patella cartilage and bone morphology in healthy adults. METHODS Two hundred and ninety-seven healthy adults aged between 50 and 79 years with no clinical history of knee pain or pathology were examined using magnetic resonance imaging (MRI). From the magnetic resonance (MR) images, the bony angles formed at the distal and proximal trochlear groove were measured, together with patella cartilage and bone volumes and patella cartilage defects. RESULTS After adjustment for potential confounders, there was an 8.70mm(3) (95% confidence interval (CI) 2.15, 15.26) increase in patella cartilage volume (P=0.009), with no increased prevalence of cartilage defects (odds ratio=0.99 (95% CI 0.96, 1.02), P=0.35), for every 1 degrees increase (i.e., as the angle became more flatter) at the distal trochlear groove. Moreover, there was a 53.86mm(3) (95% CI -90.26, -17.46) reduction in patella bone volume for every 1 degrees that the angle at the distal trochlear groove became more flattened (P=0.004). No significant association between the proximal trochlear groove angle and the patella cartilage or bone properties was observed. CONCLUSION A more flattened bony angle at the distal trochlear groove was associated with increased patella cartilage volume and reduced patella bone volume, but no increased prevalence of patella cartilage defects in adults with no history of knee pain or clinical disease. These cross-sectional findings suggest that a flattened distal trochlear groove may protect against degenerative patellofemoral conditions, such as osteoarthritis, but this will need to be confirmed in a longitudinal study.

Abstract
OBJECTIVE To determine whether the amount of joint cartilage in healthy, middle aged men is stable or changes over time, and what factors may influence this. METHODS In a cohort study, 28 healthy men (70% of the original cohort; mean (SD) age, 51.9 (12.8) years) had baseline knee magnetic resonance imaging (MRI) of their dominant knee and repeat MRI of the same knee approximately 2.0 years later. Knee cartilage volume was measured at baseline and follow up. Risk factors assessed at baseline, including sex hormones and metabolic bone markers, were tested for their association with change in knee cartilage volume over time. RESULTS Mean (SD) reduction in tibial cartilage volume per year was 162 (93) microl. This represented a 2.8% reduction in total tibial articular cartilage per year (95% confidence interval, 0.2% to 5.5%). Tibial cartilage loss was associated with serum free testosterone level, independently of age, body mass index, baseline tibial cartilage volume tibial plateau area, and total bone mineral content. Overall, testosterone accounted for 14.5% (partial r2) of the variation in change in tibial cartilage volume. There was a trend towards a positive association between tibial cartilage loss and urinary N-telopeptide cross-links of type I collagen (Ntx) (p = 0.057). CONCLUSIONS Further studies will be required to determine whether hormonal manipulation or treatment with antiresorptive drugs will reduce the risk of knee osteoarthritis in men in later life.

Abstract
Relative polycythaemia refers to raised haematocrit with normal red cell mass. Plasma volume may be reduced. This condition is associated with acute hypoxia, smoking, alcohol and diuretics. We describe two life-threatening thrombotic events in two patients with relative polycythaemia under age 40 years. The first had myocardial infarction and on admission haemoglobin was 21.6 g dL-1. The second developed pulmonary embolism and haemoglobin was 19.1 g dL-1. Both patients received antithrombotic measures and isovolumetric venesection. Sixteen patients (age <40 years) who attended our accident and emergency department in 1 year had a haemoglobin level of >18.0 g dL-1. Recognition of relative polycythaemia in at risk-individuals may help reduce thrombotic risk.

Abstract
Conventional surgery and radiotherapy for acromegaly have limitations. There are few data on the use of the somatostatin analog octreotide (Oct) as primary medical therapy. An open prospective study of 27 patients with newly diagnosed acromegaly was conducted in nine endocrine centers in the United Kingdom. Twenty patients had macroadenomas, and 7 had microadenomas. For the first 24 wk (phase 1), patients received sc Oct in an initial dose of 100 microg, 3 times daily, increased to 200 micro g three times daily after 4 wk in the 13 patients whose mean serum GH remained greater than 5 mU/liter (2 microg/liter). Five-point GH profiles were performed at 0, 4, 12, and 24 wk, and high resolution pituitary imaging using a standard protocol was performed at 0, 12, and 24 wk (magnetic resonance imaging in 25 patients and computed tomography in 2). Tumor dimensions and volumes were calculated by a central, reporting neuroradiologist, and the results were audited by a second, independent neuroradiologist. After 24 wk, 15 patients proceeded to phase 2 of the study with a direct switch to monthly injections of the depot formulation of Oct, Sandostatin long-acting release (Oct-LAR). Further GH profiles were performed at 36 and 48 wk, and pituitary imaging was performed at 48 wk. The median pretreatment serum GH concentration was 30.7 mU/liter (range, 6.7-141.4). During sc Oct, serum GH fell to less than 5 mU/liter in 9 patients (38%), and IGF-I fell to normal in 8 patients (33%). All 27 tumors shrank during sc Oct; for microadenomas the median tumor volume reduction was 49% (range, 12-73), and for macroadenomas it was 43% (range, 6-92). After 24 wk of Oct-LAR (end of phase 2), the GH level was less than 5 mU/liter in 11 of 14 patients (79%), and IGF-I was normal in 8 of 15 patients (53%). In the 15 patients given Oct-LAR (10 macroadenomas), wk 48 scans showed a further overall median tumor volume reduction of 24%. At the end of the study 79% of patients had mean serum GH levels below 5 mU/liter, 53% had normal IGF-I levels, and 73% showed greater than 30% tumor shrinkage. Twenty-nine percent of patients achieved all 3 targets, but no patient with pretreatment GH levels above 50 mU/liter did so at any stage of the study. Primary medical therapy with Oct offers the prospect of normalization of GH/IGF-I levels together with substantial tumor shrinkage in a significant subset of acromegalic patients. This is most likely to occur in patients with pretreatment GH levels less than 50 mU/liter (20 microg/liter).
