Abstract
Background
The prevalence of osteoporosis (OP) is rapidly increasing. Healthy behaviors are crucial for the management of OP. Application of the information–motivation–behavioral skills (IMB) model has been verified in various chronic diseases, but this model has not been investigated for behavioral interventions among people with OP. This study aimed to examine factors influencing OP self-management behavior and their interaction paths based on the IMB model.

Methods
We conducted a cross-sectional study using a convenience sampling method in 20 community health service centers in Shanghai, China. Predictive relationships between IMB model variables and self-management behaviors were evaluated using an anonymous questionnaire. Structural equation modeling was used to test the IMB model.

Results
In total, 571 participants completed the questionnaire, of which 461 (80.7%) were female. Participants’ mean age was 68.8 ± 10.1 years. Only 101 (17.7%) participants were classified as having better OP self-management behaviors. The model demonstrated the data had an acceptable fit. Paths from information to self-efficacy (β = 0.156, P < 0.001) and self-management behaviors (β = 0.236, P < 0.001), from health beliefs to self-efficacy (β = 0.266, P < 0.001), from medical system support to self-efficacy (β = 0.326, P < 0.001) and self-management behaviors (β = 0.230, P < 0.001), and from self-efficacy to self-management behaviors (β = 0.376, P < 0.001) were all significant and in the predicted direction.

Conclusion
This study validated the utility of the IMB model for OP self-management behaviors in this population. Middle-aged and older adult patients with OP have poor self-management behaviors. Enhanced knowledge about OP and is important for improving self-management behaviors.

Abstract
Background
In order to close existing information gaps on diabetes-related health perceptions, diabetes knowledge, and information-seeking behaviors among adults in Germany, a representative population-based survey targeting the German-speaking population 18 years and older with and without diabetes was conducted. The aim of the present work was to analyze the psychometric properties of the multi-item scales, applied in the survey in order to provide guidance for decisions on the use of these measurements for future research.

Methods
Based on data from participants who completed the final survey (N = 1479 with known diabetes; N = 2327 without known diabetes) reliability and unidimensionality of multi-item scales were tested using Cronbach’s Alpha and confirmatory factor analysis (CFA).

Results
Psychometric properties and model fit varied across scales. Cronbach’s alpha values ranged from very good to unacceptable. Model fit indices suggested evidence of a single underlying factor in some but not all scales. Adequate reliability and at least mediocre model fit were found for diabetes distress and patient-provider-relationship in people with diabetes and for perceived level of information in individuals without diabetes. Scales revealing inacceptable reliability values or not suggesting unidimensionality were e.g. diabetes-related stigmatization in both individuals with and without diabetes, self-efficacy in individuals with diabetes, and perceived personal control in those without diabetes.

Conclusion
Based on results of the current study, some of the scales applied in the survey can be recommended for present and future analyses of the survey data and for future surveys (e.g. diabetes distress, patient-provider-relationship in people with diabetes). Other scales should be interpreted and used with caution (e.g. depressive symptoms in people with diabetes) while others should be reformulated, interpreted only as single items, or need further investigation (e.g. diabetes-related stigmatization in people with and without diabetes). Findings provide researchers the opportunity to evaluate diabetes-specific scales in population-based studies of adults with and without diabetes.
A systematic review of hand-hygiene and environmental-disinfection interventions in settings with children
Authors: Staniford Leanne J. , Schmidtke Kelly A. 
Published: February 2020

Abstract
Background
Helping adults and children develop better hygiene habits is an important public health focus. As infection causing bacteria can live on one’s body and in the surrounding environment, more effective interventions should simultaneously encourage personal-hygiene (e.g. hand-hygiene) and environmental-disinfecting (e.g. cleaning surfaces). To inform the development of a future multi-faceted intervention to improve public health, a systematic literature review was conducted on behavior change interventions designed to increase hand-hygiene and environmental-disinfecting in settings likely to include children.

Methods
The search was conducted over two comprehensive data-bases, Ebsco Medline and Web of Science, to locate intervention studies that aimed to increase hand-hygiene or environmental-disinfecting behavior in settings likely to include children. Located article titles and abstracts were independently assessed, and the full-texts of agreed articles were collaboratively assessed for inclusion. Of the 2893 titles assessed, 29 met the eligibility criteria. The extracted data describe the Behavior Change Techniques (version 1) that the interventions employed and the interventions’ effectiveness. The techniques were then linked to their associated theoretical domains and to their capability-opportunity-motivation (i.e., COM-B model) components, as described in the Behavior Change Wheel. Due to the heterogeneity of the studies’ methods and measures, a meta-analysis was not conducted.

Results
A total of 29 studies met the inclusion criteria. The majority of interventions were designed to increase hand-hygiene alone (N = 27), and the remaining two interventions were designed to increase both hand-hygiene and environmental-disinfecting. The most used techniques involved shaping knowledge (N = 22) and antecedents (N = 21). Interventions that included techniques targeting four or more theoretical domains and all the capability-opportunity-motivation components were descriptively more effective.

Conclusions
In alignment with previous findings, the current review encourages future interventions to target multiple theoretical domains, across all capability-opportunity-motivation components. The discussion urges interventionists to consider the appropriateness of interventions in their development, feasibility/pilot, evaluation, and implementation stages.

Pulmonary alveolar proteinosis in Korea: analysis of prevalence and incidence via a nationwide population-based study
Authors: Yoon Hee-young , Kim Ji Hyeon , Kim Ye-Jee , Song Jin Woo 
Published: February 2020

Abstract
Background
Pulmonary alveolar proteinosis (PAP) is a very rare lung disease and its prevalence and incidence remain unclear. The prevalence and incidence of PAP were investigated by using nationwide claims data from the Korean Health Insurance Review and Assessment service.

Methods
Data were extracted for adults who visited any secondary or tertiary medical institute between 2010 and 2016 with the PAP-related Korean Classification of Disease, 7th edition code J84.0 and the Rare Intractable Disease exempted calculation code V222. To robust case definition, a narrow case definition was made when all following factors were met: 1) more than two PAP-coded visits within 1 year of the first claim, and 2) more than one claim for both chest computed tomography and diagnostic procedures (bronchoscopy or surgical lung biopsy) within 90 days before or after the first claim.

Results
A total of 182 patients (narrow, n = 82) with PAP-related codes were identified from 2010 to 2016 and 89 new patients (narrow, n = 66) visited medical institutes between 2012 and 2015. The prevalence of PAP was 4.44 (narrow: 2.27) per 106 population, with a peak age of 60–69 years. The incidence of PAP was 0.56 (narrow: 0.41) per 106 population at risk, with a peak age of 50–59 years. Among incident cases, the male-to-female ratio was 1.52 and about two-thirds had comorbidities, dyslipidaemia being the most common.

Conclusions
The prevalence and incidence of PAP in Korea are low, similar to those in other countries; however, Korean patients with PAP are characterized by older diagnostic age and a lower male-to-female ratio.

Published: February 2020

Abstract
Background
Identifying effective methods for safeguarding the efficient functioning of the healthcare system contributes significantly towards establishing a successful healthcare organization. Consequently, quality management programs are currently being implemented in healthcare as a vital strategy for patient care. Quality management encompasses protocols and guidelines in decision-making and in the evaluation of processes and treatment flowcharts, data analysis and health indicators, and addresses improvement in the interaction between different health professionals. Qualifying health professionals to perform quality management has represented a barrier to implementing a well-structured management system. Indeed, the pathway to qualifying health managers is often poorly outlined, with clear gaps in the definition of their competencies, training and career plans. Therefore, studies and education-related actions aimed at qualifying health professionals in management are vital if health services of excellence are to be established. The present study aimed to plan, develop, implement and evaluate a management specialization course in oncology using blended learning.

Methods
Following approval by the institution’s internal review board, the study was conducted at the Instituto de Medicina Integral Prof. Fernando Figueira (IMIP). The Analysis, Design, Development, Implementation and Evaluation (ADDIE) model was used to plan, develop, implement and evaluate the course. Data were collected as the course participants who had concluded all the modules evaluated the program.

Results
A management course in oncology, consisting of ten sequential modules, was developed and implemented between March 2018 and February 2019. The course consisted of monthly face-to-face encounters, each with 12 h of activities, and distance education using a virtual learning environment. Each module was presented by a specialist on the subject in question. After the end-of-course conclusion work had already been handed in and evaluated by the tutors, the participants completed a form to assess the course using Kirkpatrick’s training evaluation model.

Conclusions
A management course in oncology was developed using the ADDIE model. A high degree of satisfaction was found among the participants regarding improvements in their management skills and their professional behavior. The expectation is that this initiative will ultimately improve healthcare and reduce costs, as well as encourage further innovative educational actions for health professionals.
Reducing hospital admissions in older care home residents: a 4-year evaluation of the care home innovation Programme (CHIP)
Authors: Giebel Clarissa , Harvey Debbie , Akpan Asangaedem , Chamberlain Peter 
Published: February 2020

Abstract
Background
Older care home residents frequently attend emergency departments with a high conversion to admissions. For this purpose, a novel Care Home Innovation Programme (CHIP) was introduced with the aim of reducing potentially avoidable hospital admissions by 30%. The aim of this study is to evaluate the implementation of this innovative service in practice.

Methods
A total of 32 care homes with 1314 beds in South Sefton, Merseyside were invited to sign up to CHIP which was launched in April 2015 and continued in its entirety until June 2018. As part of the CHIP, care home matrons were introduced, new protocols were developed to address common presentations, a 24-h 7–day a week televideo system installed across all homes, and a quarterly training collaborative brought care homes together to learn and share good practices together. Data on emergency calls and calls resulting in conveyances were recorded over a four-year period, and analysed using frequency analysis.

Results
In comparison to the 12 months prior to launch, over a four-year period, implementation of the CHIP resulted in a 15% reduction of emergency calls, and in a 19% reduction of conveyances to hospital.

Conclusions
The South Sefton CHIP demonstrated itself an effective programme in reducing conveyances and consequently, hospital admissions of care home residents. This model will be superseded by the enhanced health in care homes being promoted by the NHS Long Term Care Plan.
Physician workforce in the United States of America: forecasting nationwide shortages
Authors: Zhang Xiaoming , Lin Daniel , Pforsich Hugh , Lin Vernon W. 
Published: February 2020

Abstract
Background
Physicians play a critical role in healthcare delivery. With an aging US population, population growth, and a greater insured population following the Affordable Care Act (ACA), healthcare demand is growing at an unprecedented pace. This study is to examine current and future physician job surplus/shortage trends across the United States of America from 2017 to 2030.

Methods
Using projected changes in population size and age, the authors developed demand and supply models to forecast the physician shortage (difference between demand and supply) in each of the 50 states. Letter grades were then assigned based on projected physician shortage ratios (physician shortage per 100 000 people) to evaluate physician shortages and describe the changing physician workforce in each state.

Results
On the basis of current trends, the number of states receiving a grade of “D” or “F” for their physician shortage ratio will increase from 4 in 2017 to 23 by 2030, with a total national deficit of 139 160 physician jobs. By 2030, the West is forecasted to have the greatest physician shortage ratio (69 physician jobs per 100 000 people), while the Northeast will have a surplus of 50 jobs per 100 000 people.

Conclusion
There will be physician workforce shortages throughout the country in 2030. Outcomes of this study provide a foundation to discuss effective and efficient ways to curb the worsening shortage over the coming decades and meet current and future population demands. Increased efforts to understand shortage dynamics are warranted.

Abstract
Background
In patients with vasodilatory shock, plasma concentrations of angiotensin I (ANG I) and II (ANG II) and their ratio may reflect differences in the response to severe vasodilation, provide novel insights into its biology, and predict clinical outcomes. The objective of these protocol prespecified and subsequent post hoc analyses was to assess the epidemiology and outcome associations of plasma ANG I and ANG II levels and their ratio in patients with catecholamine-resistant vasodilatory shock (CRVS) enrolled in the Angiotensin II for the Treatment of High-Output Shock (ATHOS-3) study.

Methods
We measured ANG I and ANG II levels at baseline, calculated their ratio, and compared these results to values from healthy volunteers (controls). We dichotomized patients according to the median ANG I/II ratio (1.63) and compared demographics, clinical characteristics, and clinical outcomes. We constructed a Cox proportional hazards model to test the independent association of ANG I, ANG II, and their ratio with clinical outcomes.

Results
Median baseline ANG I level (253 pg/mL [interquartile range (IQR) 72.30–676.00 pg/mL] vs 42 pg/mL [IQR 30.46–87.34 pg/mL] in controls; P <  0.0001) and median ANG I/II ratio (1.63 [IQR 0.98–5.25] vs 0.4 [IQR 0.28–0.64] in controls; P <  0.0001) were elevated, whereas median ANG II levels were similar (84 pg/mL [IQR 23.85–299.50 pg/mL] vs 97 pg/mL [IQR 35.27–181.01 pg/mL] in controls; P = 0.9895). At baseline, patients with a ratio above the median (≥1.63) had higher ANG I levels (P <  0.0001), lower ANG II levels (P <  0.0001), higher albumin concentrations (P = 0.007), and greater incidence of recent (within 1 week) exposure to angiotensin-converting enzyme inhibitors (P <  0.00001), and they received a higher norepinephrine-equivalent dose (P = 0.003). In the placebo group, a baseline ANG I/II ratio <1.63 was associated with improved survival (hazard ratio 0.56; 95% confidence interval 0.36–0.88; P = 0.01) on unadjusted analyses.

Conclusions
Patients with CRVS have elevated ANG I levels and ANG I/II ratios compared with healthy controls. In such patients, a high ANG I/II ratio is associated with greater norepinephrine requirements and is an independent predictor of mortality, thus providing a biological rationale for interventions aimed at its correction.

Gyriform restricted diffusion in adults: looking beyond thrombo-occlusions
Authors: Pai Vivek , Sitoh Yih Yian , Purohit Bela 
Published: February 2020

AbstractGyriform restricted diffusion (GRD) refers to hyperintense signal involving the cerebral cortex on diffusion-weighted images (DWI) with corresponding hypointensity on apparent diffusion coefficient (ADC) images. These changes are commonly seen following a vascular occlusion, reflecting the limitation of water molecule movement across cell membranes (restricted diffusion) due to the failure of Na+/K+-ATPase pumps (cytotoxic oedema). However, GRD can occur in several other neurological conditions as well. A thorough understanding of these conditions and their anatomic predilection plays a critical role in identifying and differentiating them from vascular thrombo-occlusion, with impact towards appropriate clinical management. This review highlights the less commonly encountered, non-stroke causes of GRD in adults with case-based examples. A tabulated chart of the patterns of cortical and subcortical involvement associated with these aetiologies is provided for a quick, pattern-based reference for daily radiological reporting.

Abstract
Background
There is a growing interest in the use of F-18 FDG PET-CT to monitor tuberculosis (TB) treatment response. Tuberculosis lung lesions are often complex and diffuse, with dynamic changes during treatment and persisting metabolic activity after apparent clinical cure. This poses a challenge in quantifying scan-based markers of burden of disease and disease activity. We used semi-automated, whole lung quantification of lung lesions to analyse serial FDG PET-CT scans from the Catalysis TB Treatment Response Cohort to identify characteristics that best correlated with clinical and microbiological outcomes.

Results
Quantified scan metrics were already associated with clinical outcomes at diagnosis and 1 month after treatment, with further improved accuracy to differentiate clinical outcomes after standard treatment duration (month 6). A high cavity volume showed the strongest association with a risk of treatment failure (AUC 0.81 to predict failure at diagnosis), while a suboptimal reduction of the total glycolytic activity in lung lesions during treatment had the strongest association with recurrent disease (AUC 0.8 to predict pooled unfavourable outcomes). During the first year after TB treatment lesion burden reduced; but for many patients, there were continued dynamic changes of individual lesions.

Conclusions
Quantification of FDG PET-CT images better characterised TB treatment outcomes than qualitative scan patterns and robustly measured the burden of disease. In future, validated metrics may be used to stratify patients and help evaluate the effectiveness of TB treatment modalities.
Neuropsychiatric symptoms in Parkinson's disease: aetiology, diagnosis and treatment

Published: February 2020

SUMMARYHistorically, Parkinson's disease was viewed as a motor disorder and it is only in recent years that the spectrum of non-motor disorders associated with the condition has been fully recognised. There is a broad scope of neuropsychiatric manifestations, including depression, anxiety, apathy, psychosis and cognitive impairment. Patients are more predisposed to delirium, and Parkinson's disease treatments give rise to specific syndromes, including impulse control disorders, dopamine agonist withdrawal syndrome and dopamine dysregulation syndrome. This article gives a broad overview of the spectrum of these conditions, describes the association with severity of Parkinson's disease and the degree to which dopaminergic degeneration and/or treatment influence symptoms. We highlight useful assessment scales that inform diagnosis and current treatment strategies to ameliorate these troublesome symptoms, which frequently negatively affect quality of life.
