AbstractBackgroundMajor Depressive Disorder (MDD) is a psychiatric disorder with a highly recurrent character, making prevention of relapse an important clinical goal. Preventive Cognitive Therapy (PCT) has been proven effective in preventing relapse, though not for every patient. A better understanding of relapse vulnerability and working mechanisms of preventive treatment may inform effective personalized intervention strategies. Neurocognitive models of MDD suggest that abnormalities in prefrontal control over limbic emotion-processing areas during emotional processing and regulation are important in understanding relapse vulnerability. Whether changes in these neurocognitive abnormalities are induced by PCT and thus play an important role in mediating the risk for recurrent depression, is currently unclear.In the Neurocognitive Working Mechanisms of the Prevention of Relapse In Depression (NEWPRIDE) study, we aim to 1) study neurocognitive factors underpinning the vulnerability for relapse, 2) understand the neurocognitive working mechanisms of PCT, 3) predict longitudinal treatment effects based on pre-treatment neurocognitive characteristics, and 4) validate the pupil dilation response as a marker for prefrontal activity, reflecting emotion regulation capacity and therapy success.MethodsIn this randomized controlled trial, 75 remitted recurrent MDD (rrMDD) patients will be included. Detailed clinical and cognitive measurements, fMRI scanning and pupillometry will be performed at baseline and three-month follow-up. In the interval, 50 rrMDD patients will be randomized to eight sessions of PCT and 25 rrMDD patients to a waiting list. At baseline, 25 healthy control participants will be additionally included to objectify cross-sectional residual neurocognitive abnormalities in rrMDD. After 18 months, clinical assessments of relapse status are performed to investigate which therapy induced changes predict relapse in the 50 patients allocated to PCT.DiscussionThe present trial is the first to study the neurocognitive vulnerability factors underlying relapse and mediating relapse prevention, their value for predicting PCT success and whether pupil dilation acts as a valuable marker in this regard. Ultimately, a deeper understanding of relapse prevention could contribute to the development of better targeted preventive interventions.Trial registrationTrial registration: Netherlands Trial Register, August 18, 2015, trial numberNL5219.

Abstract
Background
Adolescents with acute psychiatric disorders are typically treated with long-term clinical admission. However, long term admission may be associated with a variety of negative outcomes. This pilot study presents a new model of care, that is, the combined application of intensive home treatment and the possibility of short term stay at a psychiatric high & intensive care.

Methods
In total 112 referred adolescents with mixed diagnoses participated in this longitudinal observational design. Clinical outcome was measured by the Health of the Nation Outcome Scales for Children and Adolescents (HoNOSCA) which measures the severity of multiple mental health problems. The HoNOSCA was clinician-rated at intake, after two months and after four months at discharge. Change in HoNOSCA total score was analysed with paired t-tests. Outcome moderators were gender, age, primary diagnosis, clinical admission, home treatment-time, medication and additional therapies. Follow up data were completed for 62 patients after two months and for 53 after four months.

Results
Participants aged between 11 and 18 years (M = 14.8 years, SD = 0.3; 52% female). Mean HoNOSCA total score at intake was 18.8 (SD = 5.2), after two months 13.0 (SD = 5.0); after four months resulting in a score of 9.3 (SD = 5.2). None of the moderators tested showed a significant effect on HoNOSCA scores. However, a control group could not be used because of the severe psychopathology and high risk for suicidality and the lack of an effective treatment intervention for a comparable study group.

Conclusion
With a symptom decrease of over 50% within four months as measured by the HoNOSCA, including less risk for hospitalization, this new model appears promising and of clinical relevance. Nevertheless, further research regarding stability of treatment outcome is warranted and evaluation of long-term effects of this model in follow-up studies is needed.
Validation of the patient activation measure in patients at discharge from hospitals and at distance from hospital care in Sweden

Published: December 2019

Abstract
Background
The Patient Activation Measure (PAM) is a recognized measure of how active patients are in their care, and has been translated into several languages and cultural contexts. Patient activity, self-care, and health literacy have become increasingly important aspects of health care, and thus reliable measures of these are needed. However, a Swedish translation of PAM is currently lacking. The aim of the study was to translate and assess the validity and reliability of the Swedish PAM-13.

Methods
A self-report questionnaire was handed out to 521 patients at ten medical, geriatric, and surgical wards, and one Virtual Health Room. The Rasch model was employed, using the partial credit model, to assess the functioning of the PAM scale, item fit, targeting, unidimensionality, local independence, differential item functioning (DIF), and person-separation index. Evidence of substantive, content, structural, and external validity was examined.

Results
Of the 521 patients who were consecutively handed a questionnaire, 248 consented to participate, yielding a response rate of 47.6%. The average measure for each category advanced monotonically. The difficulty of the PAM items ranged from − 1.55 to 1.26. The infit and outfit values for the individual items were acceptable. Items 1, 2, and 4 showed disordered thresholds. The mean person location was 1.48 (SD = 1.66). The person-item map revealed that there were no item representations at the top of the scale. The evidence for unidimensionality was ambiguous and response dependency was seen in some items. DIF was found for age. The person separation index was 0.85.

Conclusion
The Swedish PAM-13 was reliable, but was not conclusively found to represent one underlying construct. It seems that the Swedish PAM-13 lacks strong evidence for substantive, content, and structural validity. Although valid and reliable measures of ability for activation in self-care among patients are highly warranted, we recommend further development of PAM-13 before application in everyday clinical care.

Abstract
Background
This cross-sectional study aims to validate the Chinese version of Zelaya’s HIV-related Stigma Scale (CVZHSS) among a large undergraduate sample in mainland China, and apply it to measure the level of different dimensions of stigma and their respective determinants.

Methods
From September 10, 2018, to January 9, 2019, a total of 10,665 eligible undergraduates conveniently drawn from 30 provinces in mainland China (except for Tibet) completed the self-designed online questionnaire distributed via sojump.com voluntarily, anonymously and confidentially. Both exploratory and confirmatory factor analyses (EFA and CFA) were first performed to test its construct validity, Cronbach’s alpha was then used to assess its internal consistency, and Logistic regression analyses were finally carried out to identify predictors of various dimensions of stigma.

Results
As expected from the original model, four factors (i.e., “fear of casual transmission”, “moral judgment”, “personal stigma” and “perceived community stigma”) were extracted using principal component analysis with varimax rotation, accounting for 63.26% of the total variance. The CFA further confirmed the four-factor construct (CFI = 0.92, GFI = 0.91, RMSEA = 0.07). In addition, all the four factors demonstrated acceptable internal consistency with Cronbach’s alpha ranging from 0.83 to 0.92. Stigma as measured by “fear of casual transmission” (74.4%), “moral judgement” (61.6%), “personal stigma” (79.0%) and “perceived community stigma”(36.5%) is highly prevalent among undergraduates. Except for non-freshmen, less knowledge about HIV and unsafe sex which were consistently associated with higher levels of stigma in all four dimensions, other eight variables including gender, residential area, major, sexual orientation, having ever being tested perception of HIV risk, willingness to utilize HTC service and awareness of the national AIDS policy played differential roles in affecting different dimensions of stigma.

Conclusions
The CVZHSS is a reliable and valid measurement tool and can be used to identify undergraduates with high levels of stigma. However, the four dimensions (Fear, moral judgement, personal stigma and perceived community stigma) were respectively influenced by different determinants, and thus should be treated independently when designing, implementing and evaluating stigma reduction programs.

AbstractBackgroundPulmonary veno-occlusive disease (PVOD) is a rare condition with poor prognosis, and lung transplantation is recommended as the only curative therapy. The role of pulmonary arterial hypertension targeted therapy in PVOD remains controversial, and long-term effects of targeted therapy have been rarely reported. This study aims to retrospectively evaluate the role of targeted therapy in PVOD patients and the long-term outcome.MethodsPVOD patients with good responses to targeted therapies were analyzed, and data pre- and post- targeted therapies were compared. An overview of the effects of targeted therapies on PVOD patients was also conducted.ResultsFive genetically or histologically confirmed PVOD patients received targeted therapies and showed good responses. Their mean pulmonary arterial pressure by right heart catheterization was 62.0 ± 11.7 mmHg. Two receiving monotherapy got stabilized, and three receiving sequential combination therapy got improved, cardiac function and exercise capacity significantly improved after treatments. No pulmonary edema occurred. The mean time from the first targeted therapy to the last follow up was 39.3 months, and the longest was 9 years. A systematic review regarding the effects of targeted therapies on PVOD patients indicated majorities of patients got hemodynamics or 6-min walk distance improved, and 26.7% patients developed pulmonary edema. The interval from targeted drugs use to death ranged from 71 min to over 4 years.ConclusionsCautious use of targeted therapy could safely and effectively improve or stabilize hemodynamics and exercise capacity of some patients without any complications. PVOD patients could live longer than expected.
A patient with extensive cerebral calcification due to pseudohypoparathyroidism: a case report
Authors: De Silva S. W. , De Silva S. D. N. , De Silva C. E. 
Published: December 2019

Abstract
Background
Pseudohypoparathyroidism(PHP) is a heterogeneous group of disorders due to impaired activation of c AMP dependant pathways following binding of parathyroid hormone (PTH) to its receptor. In PHP end organ resistance to PTH results in hypocalcaemia, hyperphosphataemia and high PTH levels.

Case presentation
A 59 year old male presented with a history of progressive impairment of speech and unsteadiness of gait for 1 week and acute onset altered behavior for 1 day and one episode of generalized seizure. His muscle power was grade four according to MRC (medical research council) scale in all limbs and Chovstek’s and Trousseau’s signs were positive. Urgent non contrast computed tomography scan of the brain revealed extensive bilateral cerebral and cerebellar calcifications. A markedly low ionized calcium level of 0.5 mmol/l, an elevated phosphate level of 9.5 mg/dl (reference range: 2.7–4.5 mg/dl) and an elevated intact PTH of 76.3 pg/l were noted. His renal functions were normal. His hypocalcemia was accentuated by the presence of hypomagnesaemia. His 25 hydroxy vitamin D level was only marginally low which could not account for severe hypocalcaemia. A diagnosis of pseudohypoparathyroidism without phenotypic defects, was made due to hypocalcaemia and increased parathyroid hormone levels with cerebral calcifications. The patient was treated initially with parenteral calcium which was later converted to oral calcium supplements. His coexisting Vitamin D deficiency was corrected with 1αcholecalciferol escalating doses. His hypomagnesaemia was corrected with magnesium sulphate parenteral infusions initially and later with oral preparations. With treatment there was a significant clinical and biochemical response.

Conclusion
Pseudohypoparathyroidism can present for the first time in elderly resulting in extensive cerebral calcifications. Identification and early correction of the deficit will result in both symptomatic and biochemical response.

Abstract
Background
Observational studies examining the association between oral health and juvenile idiopathic arthritis (JIA) among children and adolescents have reported inconsistent findings. The aims of this systematic review and meta-analysis were to ascertain a potential difference in oral health and oral health-related quality of life (OHRQoL) among children and adolescents with JIA and healthy peers, and to assess the association of prevalence of oral diseases/conditions, temporomandibular disorders (TMD), including temporomandibular joint (TMJ) diseases, in relation to activity and severity of JIA.

Method
Medline Ovid, Embase, CINAHL, SweMed+ and Cochrane Library were searched up to 25 November 2018. All articles published in English, German and Scandinavian languages focusing on children and adolescents with JIA and without JIA in relation to oral health measures, were considered. Two authors independently evaluated observational studies for inclusion. The study quality was assessed using modified Newcastle Ottawa Scale. Meta-analysis was performed for studies focusing on dental caries as an outcome.

Results
Nineteen articles met the inclusion criteria, covering a range of oral diseases/conditions and OHRQoL. Eighteen studies had cross-sectional design. No mean difference of dmft/DMFT indices (decayed/missed/filled teeth) was observed between the JIA - and healthy group. None of the oral health measures including dental erosive wear, enamel defects, dental maturation and OHRQoL, indicated better oral health among children and adolescents with JIA compared to healthy group. However, periodontal conditions and TMD were more predominant among children and adolescents with JIA compared to healthy peers.

Conclusions
Based on the cross-sectional studies, periodontal diseases and TMD were found to be more frequent in children and adolescents with JIA compared to healthy peers. Furthermore, more high-quality studies with large sample size are needed before we infer any concrete conclusion regarding the association between the prevalence of oral and TMJ diseases or oral conditions in relation to activity and severity of JIA.
Choices and services related to contraception in the Gaza strip, Palestine: perceptions of service users and providers
Authors: Böttcher Bettina , Abu-El-Noor Mysoon , Abu-El-Noor Nasser 
Published: December 2019

Abstract
Background
Reliable contraception enables women and men to plan their family sizes and avoid unintended pregnancies, which can cause distress and anxiety, but also increase maternal mortality. This study explored potential barriers to contraceptive use for women in the Gaza Strip, Palestine from user and provider perspectives.

Methods
A convenient sample was used to recruit women, who were current contraception users, from three healthcare clinics that provide family planning care, two governmental and one non-governmental. A 16-item questionnaire was completed by 204 women, including socio-demographic data, contraceptive use and eight questions exploring user experience. Additionally, 51 women attended focus groups for a deeper insight into their contraceptive use experience and potential barriers. Furthermore, 14 healthcare providers were interviewed about their experience with service provision. Quantitative data are presented as means and frequencies and qualitative data were analysed item by item and are presented in themes jointly with the quantitative data.

Results
Women reported usage of only three main modern methods of contraception with 35.2% using intrauterine devices, 25.8% combined oral contraception and 16.4% condoms, while only 3.1% used the hormonal implant. Expectations from family planning services were low with most women attending the clinic having already decided their contraceptive method with decisions being made by husbands (41.2%) or women jointly with their partner (33.3%), only 13.7% took advice from service providers. Healthcare providers experienced high prevalence of beliefs that modern contraceptives cause infertility and cancer. Main barriers to effective family planning services were misconceptions of potential harm, poor availability and limited choice of contraceptive methods.

Conclusion
Women’s contraceptive choices in Gaza are limited by prevalent misconceptions and fears as well as recurring shortages, negatively impacting fertility control. Men are a major factor in choosing a contraceptive method, however, they have limited access to information and therefore, potentially more misconceptions. Therefore, male community members need to be included in the delivery of information on contraceptives to increase women’s choice. Furthermore, greater access to long-acting reversible contraceptives, such as the hormonal implant, and improved availability might be key factors in improving contraceptive uptake in Gaza and, thus, reducing unintended pregnancies.
Ethical concerns with the use of intelligent assistive technology: findings from a qualitative study with professional stakeholders
Authors: Wangmo Tenzin , Lipps Mirjam , Kressig Reto W. , Ienca Marcello 
Published: December 2019

Abstract
Background
Advances in artificial intelligence (AI), robotics and wearable computing are creating novel technological opportunities for mitigating the global burden of population ageing and improving the quality of care for older adults with dementia and/or age-related disability. Intelligent assistive technology (IAT) is the umbrella term defining this ever-evolving spectrum of intelligent applications for the older and disabled population. However, the implementation of IATs has been observed to be sub-optimal due to a number of barriers in the translation of novel applications from the designing labs to the bedside. Furthermore, since these technologies are designed to be used by vulnerable individuals with age- and multi-morbidity-related frailty and cognitive disability, they are perceived to raise important ethical challenges, especially when they involve machine intelligence, collect sensitive data or operate in close proximity to the human body. Thus, the goal of this paper is to explore and assess the ethical issues that professional stakeholders perceive in the development and use of IATs in elderly and dementia care.

Methods
We conducted a multi-site study involving semi-structured qualitative interviews with researchers and health professionals. We analyzed the interview data using a descriptive thematic analysis to inductively explore relevant ethical challenges.

Results
Our findings indicate that professional stakeholders find issues of patient autonomy and informed consent, quality of data management, distributive justice and human contact as ethical priorities. Divergences emerged in relation to how these ethical issues are interpreted, how conflicts between different ethical principles are resolved and what solutions should be implemented to overcome current challenges.

Conclusions
Our findings indicate a general agreement among professional stakeholders on the ethical promises and challenges raised by the use of IATs among older and disabled users. Yet, notable divergences persist regarding how these ethical challenges can be overcome and what strategies should be implemented for the safe and effective implementation of IATs. These findings provide technology developers with useful information about unmet ethical needs. Study results may guide policy makers with firsthand information from relevant stakeholders about possible solutions for ethically-aligned technology governance.
Fast read alignment with incorporation of known genomic variants
Authors: Guo Hongzhe , Liu Bo , Guan Dengfeng , Fu Yilei , Wang Yadong 
Published: December 2019

Abstract
Background
Many genetic variants have been reported from sequencing projects due to decreasing experimental costs. Compared to the current typical paradigm, read mapping incorporating existing variants can improve the performance of subsequent analysis. This method is supposed to map sequencing reads efficiently to a graphical index with a reference genome and known variation to increase alignment quality and variant calling accuracy. However, storing and indexing various types of variation require costly RAM space.

Methods
Aligning reads to a graph model-based index including the whole set of variants is ultimately an NP-hard problem in theory. Here, we propose a variation-aware read alignment algorithm (VARA), which generates the alignment between read and multiple genomic sequences simultaneously utilizing the schema of the Landau-Vishkin algorithm. VARA dynamically extracts regional variants to construct a pseudo tree-based structure on-the-fly for seed extension without loading the whole genome variation into memory space.

Results
We developed the novel high-throughput sequencing read aligner deBGA-VARA by integrating VARA into deBGA. The deBGA-VARA is benchmarked both on simulated reads and the NA12878 sequencing dataset. The experimental results demonstrate that read alignment incorporating genetic variation knowledge can achieve high sensitivity and accuracy.

Conclusions
Due to its efficiency, VARA provides a promising solution for further improvement of variant calling while maintaining small memory footprints. The deBGA-VARA is available at: https://github.com/hitbc/deBGA-VARA.
