Artificial Intelligence-Assisted Online Social Therapy for Youth Mental Health

Introduction: Benefits from mental health early interventions may not be sustained over time, and longer-term intervention programs may be required to maintain early clinical gains. However, due to the high intensity of face-to-face early intervention treatments, this may not be feasible. Adjunctive internet-based interventions specifically designed for youth may provide a cost-effective and engaging alternative to prevent loss of intervention benefits. However, until now online interventions have relied on human moderators to deliver therapeutic content. More sophisticated models responsive to user data are critical to inform tailored online therapy. Thus, integration of user experience with a sophisticated and cutting-edge technology to deliver content is necessary to redefine online interventions in youth mental health. This paper discusses the development of the moderated online social therapy (MOST) web application, which provides an interactive social media-based platform for recovery in mental health. We provide an overview of the system's main features and discus our current work regarding the incorporation of advanced computational and artificial intelligence methods to enhance user engagement and improve the discovery and delivery of therapy content. Methods: Our case study is the ongoing Horyzons site (5-year randomized controlled trial for youth recovering from early psychosis), which is powered by MOST. We outline the motivation underlying the project and the web application's foundational features and interface. We discuss system innovations, including the incorporation of pertinent usage patterns as well as identifying certain limitations of the system. This leads to our current motivations and focus on using computational and artificial intelligence methods to enhance user engagement, and to further improve the system with novel mechanisms for the delivery of therapy content to users. In particular, we cover our usage of natural language analysis and chatbot technologies as strategies to tailor interventions and scale up the system. Conclusions: To date, the innovative MOST system has demonstrated viability in a series of clinical research trials. Given the data-driven opportunities afforded by the software system, observed usage patterns, and the aim to deploy it on a greater scale, an important next step in its evolution is the incorporation of advanced and automated content delivery mechanisms.
Method of delivery and pregnancy outcomes in Asia: the WHO global survey on maternal and perinatal health 2007–08

BACKGROUND
There has been concern about rising rates of caesarean section worldwide. This Article reports the third phase of the WHO global survey, which aimed to estimate the rate of different methods of delivery and to examine the relation between method of delivery and maternal and perinatal outcomes in selected facilities in Africa and Latin America in 2004-05, and in Asia in 2007-08.


METHODS
Nine countries participated in the Asia global survey: Cambodia, China, India, Japan, Nepal, Philippines, Sri Lanka, Thailand, and Vietnam. In each country, the capital city and two other regions or provinces were randomly selected. We studied all women admitted for delivery during 3 months in institutions with 6000 or fewer expected deliveries per year and during 2 months in those with more than 6000 deliveries. We gathered data for institutions to obtain a detailed description of the health facility and its resources for obstetric care. We obtained data from women's medical records to summarise obstetric and perinatal events.


FINDINGS
We obtained data for 109 101 of 112 152 deliveries reported in 122 recruited facilities (97% coverage), and analysed 107 950 deliveries. The overall rate of caesarean section was 27.3% (n=29 428) and of operative vaginal delivery was 3.2% (n=3465). Risk of maternal mortality and morbidity index (at least one of: maternal mortality, admission to intensive care unit [ICU], blood transfusion, hysterectomy, or internal iliac artery ligation) was increased for operative vaginal delivery (adjusted odds ratio 2.1, 95% CI 1.7-2.6) and all types of caesarean section (antepartum without indication 2.7, 1.4-5.5; antepartum with indication 10.6, 9.3-12.0; intrapartum without indication 14.2, 9.8-20.7; intrapartum with indication 14.5, 13.2-16.0). For breech presentation, caesarean section, either antepartum (0.2, 0.1-0.3) or intrapartum (0.3, 0.2-0.4), was associated with improved perinatal outcomes, but also with increased risk of stay in neonatal ICU (2.0, 1.1-3.6; and 2.1, 1.2-3.7, respectively).


INTERPRETATION
To improve maternal and perinatal outcomes, caesarean section should be done only when there is a medical indication.

Turnover intention in new graduate nurses: a multivariate analysis

AIM
This paper is a report of a study to determine the relationship of new nurse turnover intent with individual characteristics, work environment variables and organizational factors and to compare new nurse turnover with actual turnover in the 18 months of employment following completion of a residency.


BACKGROUND
Because of their influence on patient safety and health outcomes nurse turnover and turnover intent have received considerable attention worldwide. When nurse staffing is inadequate, especially during nursing shortages, unfavourable clinical outcomes have been documented.


METHOD
Prospective data collection took place from 1999 to 2006 with 889 new paediatric nurses who completed the same residency. Scores on study instruments were related to likelihood of turnover intent using logistic regression analysis models. Relationships between turnover intent and actual turnover were compared using Kaplan-Meier survivorship.


RESULTS
The final model demonstrated that older respondents were more likely to have turnover intent if they did not get their ward choice. Also higher scores on work environment and organizational characteristics contributed to likelihood that the new nurse would not be in the turnover intent group. These factors distinguish a new nurse with turnover intent from one without 79% of the time. Increased seeking of social support was related to turnover intent and older new graduates were more likely to be in the turnover intent group if they did not get their ward choice.


CONCLUSION
When new graduate nurses are satisfied with their jobs and pay and feel committed to the organization, the odds against turnover intent decrease.
Collision Avoidance in Air Traffic Management: A Mixed-Integer Linear Optimization Approach

This paper tackles the collision-avoidance problem in air traffic management. The problem consists of deciding the best strategy for new aircraft configurations (velocity and altitude changes) such that all conflicts in the airspace, i.e., the loss of the minimum safety distance that has to be kept between two aircraft, are avoided. A mixed 0-1 linear optimization model based on geometric transformations for collision avoidance between an arbitrary number of aircraft in the airspace is developed. Knowing the initial coordinates, angle direction, and level flight, the new configuration for each aircraft is established by minimizing several objective functions, e.g., velocity variation and total number of changes (velocity and altitude), and forcing to return to the original flight configuration when no aircraft are in conflict. Due to the small computational time for the execution, the new configuration approach can be used in real time by using optimization software.
Do metronomes improve the quality of life in people with Parkinson's disease? A pragmatic, single-blind, randomized cross-over trial.

OBJECTIVE
To evaluate the effect of acoustic cueing using metronomes on the quality of life of people with moderate to severe Parkinson's disease.


STUDY DESIGN
Pragmatic, single-blind, randomized cross-over trial.


PARTICIPANTS
Forty-two people aged 50-85 years, in Hoehn and Yahr stage II-IV and on stable medication. Eight were lost to follow-up.


INTERVENTION
Participants were randomized using concealed allocation to either an early group (n = 21) to receive an electronic metronome without therapy but limited support (5-10 minutes instruction and on-demand telephone assistance) for four weeks, or a late group (n = 21) to receive the same intervention at 10 weeks. In both groups the beat frequency was initially set to be comfortable for walking.


OUTCOMES MEASURES
Primary and secondary outcomes were measured at baseline, 4, 10 and 14 weeks using the Parkinson's Disease Questionnaire 39 (PDQ-39), the Short Form 36 version 2 (SF-36 version 2) and a falls diary.


RESULTS
There were positive effects in six domains of the SF-36 version 2 and eight domains of the PDQ-39, although only one mean difference was clinically important: the role limitation (emotional) domain of SF-36 version 2 (a mean difference of 3.77, 95% confidence interval (CI), -2.68 to 10.22), a secondary outcome. None of these changes were statistically significant. There were no statistically significant differences in falls rates over the study period. Ten participants (24%) wanted to continue with their metronomes at the end of the study.


CONCLUSION
To demonstrate metronomes are beneficial on the role limitation domain of the SF-36 version 2 in people with moderate to severe Parkinson's disease a sample size of 600 would be required.
Depression and functional outcome after stroke: the effect of antidepressant therapy on functional recovery.

AIM
The optimal strategy to prevent post-stroke depression is an important but still-unresolved issue. This study examined the differences in functional recovery among post-stroke depressed patients (DP) compared to post-stroke non-depressed patients (NDP) over the course of six months after stroke.


METHODS
On the basis of a semistructured psychiatric examination, DSM-IV diagnostic criteria and the Hamilton Depression score, a consecutive series of ischemic or hemorrhagic stroke patients were included in this study. They had suffered from first-time stroke, and did not have depression diagnosis before. During follow-up, treatment with 20 mg/day citalopram per os was initiated whenever a diagnosis of depression was established. Their functional recoveries were assessed using the Scandinavian Stroke Scale, the modified Rankin scale and the Barthel index during acute hospitalization, at the time of depression diagnosis and at the third and sixth month follow-up visits.


RESULTS
Forty patients met the diagnostic criteria and 11 patients suffered from depression during the follow-up period. There were no differences in demographic variables, lesion characteristics and neurological symptoms between DP and NDP. Functional recovery in DP was impaired in comparison to NDP (P<0.05). All DP, whose mood improved after administration of citalopram, and improved daily functions living functions during the follow-up.


CONCLUSION
This study's findings suggest that remission of post-stroke depression is associated with improvement in functional recovery. Early diagnosis and effective treatment of depression will help the rehabilitation outcome of stroke patients.
Effect of transcranial direct current stimulation combined with gait and mobility training on functionality in children with cerebral palsy: study protocol for a double-blind randomized controlled clinical trial

BACKGROUND
The project proposes three innovative intervention techniques (treadmill training, mobility training with virtual reality and transcranial direct current stimulation that can be safely administered to children with cerebral palsy. The combination of transcranial stimulation and physical therapy resources will provide the training of a specific task with multiple rhythmic repetitions of the phases of the gait cycle, providing rich sensory stimuli with a modified excitability threshold of the primary motor cortex to enhance local synaptic efficacy and potentiate motor learning.


METHODS/DESIGN
A prospective, double-blind, randomized, controlled, analytical, clinical trial will be carried out.Eligible participants will be children with cerebral palsy classified on levels I, II and III of the Gross Motor Function Classification System between four and ten years of age. The participants will be randomly allocated to four groups: 1) gait training on a treadmill with placebo transcranial stimulation; 2) gait training on a treadmill with active transcranial stimulation; 3) mobility training with virtual reality and placebo transcranial stimulation; 4) mobility training with virtual reality and active transcranial stimulation. Transcranial direct current stimulation will be applied with the anodal electrode positioned in the region of the dominant hemisphere over C3, corresponding to the primary motor cortex, and the cathode positioned in the supraorbital region contralateral to the anode. A 1 mA current will be applied for 20 minutes. Treadmill training and mobility training with virtual reality will be performed in 30-minute sessions five times a week for two weeks (total of 10 sessions). Evaluations will be performed on four occasions: one week prior to the intervention; one week following the intervention; one month after the end of the intervention;and 3 months after the end of the intervention. The evaluations will involve three-dimensional gait analysis, analysis of cortex excitability (motor threshold and motor evoked potential), Six-Minute Walk Test, Timed Up-and-Go Test, Pediatric Evaluation Disability Inventory, Gross Motor Function Measure, Berg Balance Scale, stabilometry, maximum respiratory pressure and an effort test.


DISCUSSION
This paper offers a detailed description of a prospective, double-blind, randomized, controlled, analytical, clinical trial aimed at demonstrating the effect combining transcranial stimulation with treadmill and mobility training on functionality and primary cortex excitability in children with Cerebral Palsy classified on Gross Motor Function Classification System levels I, II and III. The results will be published and will contribute to evidence regarding the use of treadmill training on this population.

Effect of cooling heat-stressed dairy cows during the dry period on insulin response.

Heat stress (HT) during the dry period affects hepatic gene expression and adipose tissue mobilization during the transition period. In addition, it is postulated that HT may alter insulin action on peripheral tissues. Our objective was to evaluate the effect of cooling heat-stressed cows during the dry period on insulin effects on peripheral tissues during the transition period. Cows were dried off 46 d before expected calving and assigned to 1 of 2 treatments: HT (n = 16) or cooling (CL, n = 16). During the dry period, the average temperature-humidity index was 78, but CL cows were cooled with sprinklers and fans, whereas HT cows were not. After calving, all cows were housed and managed under the same conditions. Rectal temperatures were measured twice daily (0730 and 1430 h) and respiration rate recorded 3 times weekly during the dry period. Dry matter intake was recorded daily from dry-off to 42 d relative to calving (DRC). Body weight and body condition score were measured weekly from dry-off to 42 DRC. Milk yield and composition were recorded daily to 42 wk postpartum. Glucose tolerance tests (GTT) and insulin challenges (IC) were performed at dry-off, -14, 7, and 28 DRC in a subset of cows (HT, n = 8; CL, n = 8). Relative to HT, CL cows had lower rectal temperatures (39.3 vs. 39.0°C) in the afternoon and respiration rate (69 vs. 48 breath/min). Cows from the cooling treatment tended to consume more feed than HT cows prepartum and postpartum. Compared with HT, CL cows gained more weight before calving but lost more weight and body condition in early lactation. Cows from the cooling treatment produced more milk than HT cows (34.0 vs. 27.7 kg/d), but treatments did not affect milk composition. Treatments did not affect circulating insulin and metabolites prepartum, but CL cows had decreased glucose, increased nonesterified fatty acid, and tended to have lower insulin concentrations in plasma postpartum compared with HT cows. Cooling prepartum HT cows did not affect the insulin responses to GTT and IC during the transition period and glucose responses to GTT and IC at -14 and 28 DRC were not affected by treatments. At 7 DRC, CL cows tended to have slower glucose clearance to GTT and weaker glucose response to IC relative to HT cows. Cows from the cooling treatment had stronger nonesterified fatty acid responses to IC postpartum but not prepartum compared with HT. In conclusion, cooling heat-stressed dairy cows in the dry period reduced insulin effects on peripheral tissues in early lactation but not in the dry period.
Circulating adhesion molecules ICAM-1, VCAM-1 and E-selectin in systemic vasculitis : marked differences between Wegener's granulomatosis and systemic lupus erythematosus

Inflammatory systemic disorders with renal tissue damage require the adherence of polymorphonuclear leukocytes to the endothelium, which is mediated by cell surface adhesion molecules. This study measured the serum concentrations of circulating adhesion molecules [intercellular adhesion molecule 1 (cICAM-1), vascular cell adhesion molecule 1 (cVCAM-1), cE-selectin] by sandwich enzyme-linked immunosorbent assay in Wegener's granulomatosis (n = 25) and systemic lupus erythematosus (n = 50). Active Wegener's granulomatosis with cellular crescent formation was associated with significantly raised cICAM-1 levels, an elevated histological activity index, and a high rate of hemodialysis in comparison to Wegener's granulomatosis with fibrocellular crescents or lupus nephritis. The activity index and cICAM-1 levels can be used as parameters to predict renal outcome in Wegener's granulomatosis. cVCAM-1 levels in Wegener's granulomatosis were significantly higher in patients with hemodialysis compared to those without hemodialysis. In lupus nephritis only cVCAM-1, not cICAM-1 or cE-selectin, were significantly higher (P < 0.01) than controls. cVCAM-1 levels in both diseases were significantly higher than in controls. Only in Wegener's granulomatosis did cICAM-1 and cVCAM-1 levels decrease with clinical remission; in systemic lupus erythematosus the levels remained unchanged. cE-selectin levels were not significantly elevated in systemic vasculitis or collagen disease although individual patients revealed high serum concentrations. These data suggest that levels of circulating adhesion molecules reflect different pathophysiological processes in systemic vasculitis and collagen disease and may be used as markers of disease activity and renal outcome.
When Asperger's Disorder Came Out.

BACKGROUND
In 2013, the American Psychiatric Association removed Asperger's Disorder from the DSM, offering instead the new DSM-5 diagnosis: Autism Spectrum Disorder. This change has been hailed the most controversial exclusion from the DSM, yet unlike the 1973 removal of homosexuality from DSM-III, Asperger's disorder has not been demedicalised. Rather, the disorder has simply been reclassified as part of the DSM-5 Autism Spectrum and therefore retains its fundamental characteristic as a mental disorder owing to its inclusion within the sphere of the DSM.


METHODS
This paper is based on a review of the current academic literature in conjunction with careful reading of the DSM-5.


RESULTS
Removing the Asperger's label, valued by patients for its distinctiveness from autism brings with it the potential to inflict iatrogenic harm.


DISCUSSION
This paper demonstrates how the DSM-5 reclassification has the potential to threaten the identity of those affected, and discusses the problem of autism as a stigmatizing diagnostic label.


CONCLUSIONS
A case is made for the use of tandem social/colloquial - medical/technical terminology to refer to the conditions classified under DSM-5 Autism Spectrum Disorder, in order to square the circle of social concerns regarding identity and stigma with the need for diagnostic clarity to continue to advance medical practice.
Occurrence and trends in ski injuries in Norway.

OBJECTIVES
To provide an overview of ski injuries in Norway and to describe the changes between 1990 and 1996.


METHODS
All ski injuries (7966) treated at four hospitals providing health care to a defined population of about 11% of the Norwegian population were registered prospectively from 1990 to 1996. For this study, 6462 injuries sustained in cross country skiing, downhill skiing, telemark skiing, and snowboarding were selected for further analysis.


RESULTS
The relative distribution of ski injuries by type of skiing changed significantly from 1990 to 1996 (p<0.001). Injuries from snowboarding showed the highest relative increase, and those sustained during downhill skiing showed a decline. The proportion of fractures in all types of skiing increased during the study period (p=0.001). The proportion of injuries to knee/lower leg decreased and the proportion to the forearm/wrist/hand increased during the study period (p=0.03). The mean age of the injured skiers differed significantly among the different types of skiing activity (p<0.001): cross country skiers were the oldest followed by telemark skiers, downhill skiers, and snowboarders.


CONCLUSIONS
Ski injury surveillance results in early detection of changes in temporal injury trends, allowing timely adjustment of injury prevention strategies. Injuries from snowboarding are on the increase in Norway, warranting more effective injury prevention measures.
Mechanical suture in rectal cancer

BACKGROUND AND AIMS
Colorectal cancer is one of the most frequent digestive malignancies, being the third cause of death by cancer, despite early diagnosis and therapeutic progress made over the past years. Standard treatment in these patients is to preserve the anal sphincter with restoration of intestinal function by mechanical colorectal anastomosis or coloanal anastomosis, and to maintain genitourinary function by preservation of hypogastric nerves.


METHODS
In order to emphasize the importance of this surgical technique in the Fourth Surgical Clinic of the CF Clinical Hospital Cluj-Napoca, we conducted a prospective observational interventional study over a 3-year period (2013-2016) in 165 patients hospitalized for rectal and rectosigmoid adenocarcinoma in various disease stages, who underwent Dixon surgery using the two techniques of manual and mechanical end-to-end anastomosis. For mechanical anastomosis, we used Covidien and Panther circular staplers. The patients were assigned to two groups, group A in which Dixon surgery with manual end-to-end anastomosis was performed (116 patients), and group B in which Dixon surgery with mechanical end-to-end anastomosis was carried out (49 patients).


RESULTS
Mechanical anastomosis allowed to restore intestinal continuity following low anterior resection in 21 patients with lower rectal adenocarcinoma compared to 2 patients in whom intestinal continuity was restored by manual anastomosis, with a statistically significant difference (p<0.000001). The double-row mechanical suture technique is associated with a reduced duration of surgery (121.67 minutes for Dixon surgery with mechanical anastomosis, compared to 165.931 minutes for Dixon surgery with manual anastomosis, p<0.0001).


CONCLUSION
The use of circular transanal staplers facilitates end-to-end anastomosis by double-row mechanical suture, allowing to perform low anterior resection in situations when the restoration of intestinal continuity by manual anastomosis is technically not possible, with the aim to preserve the anal sphincter, to restore intestinal function and maintain genitourinary function through preservation of hypogastric nerves.
