Observations of visible argon line emissions and its spatial profile from Aditya-U tokamak plasma

The spectroscopic studies of medium and high Z impurities have been the subject of interest in fusion research due to their role in mitigating plasma disruption and reducing heat load on the plasma facing components. Line emissions from these impurities provide the rotation velocity and ion temperature measurements along with the understanding of the overall impurity behavior in plasma. In the Aditya-U tokamak, the spatially resolved Ar II line emissions have been observed using a high resolution multi-track spectroscopic diagnostic consisting of a 1 m Czerny-Turner spectrometer coupled with a charge coupled device (CCD) detector using seven lines of sight viewing plasma tangentially along the toroidal direction. The spatially resolved Ar II lines at 458.96 nm have been observed. The singly ionized Ar emission peaks at the radial location of ρ = 0.8 of the plasma having a minor radius of 25 cm. Moreover, a 0.5 m UV-visible spectrometer coupled with a CCD detector and having a line of sight passing through the plasma midplane from the radial port was used to record visible Ar survey spectra within the 670-810 nm wavelength range, and all these lines have been identified for further analysis.

P36: SOMATIC SYMPTOM DISORDER (SSD) AND ABDOMINAL PAIN: INCREASED OPIOID PRESCRIBING IN SURGICAL PATIENTS

Introduction

Undifferentiated pain, and pain out of proportion of diagnosed pathology are sources of frustration to clinician and patient. SSD is a DSM-V diagnosis that has consolidated the previous diagnoses of psychogenic pain. It is a health anxiety condition, where sufferers experience multiple somatic symptoms which cause anxiety and distress. This anxiety results in frequent ED and GP presentations, extensive investigations, and increased opioid prescription. However, opioids do little to alleviate symptoms. Treatment should focus on underlying anxiety and depression.

Population studies show SSD prevalence to be 15-20%, however SSD has never been studied in the surgical population. We hypothesized that the rates of SSD in the surgical population reflects that in primary care, and that SSD sufferers are more likely to be prescribed opioid analgesia.

Method

Adult patients admitted with abdominal pain of any non-traumatic aetiology to the Acute General Surgical Unit at a major tertiary hospital are being screened for SSD using the PHQ-15 questionnaire, and opioid prescription is being recorded.

Result

400 participants have been recruited with a total SSD prevalence of 20%. Opioid prescribing rises sharply with SSD diagnosis. The average opioid prescription appears to be 3 times higher in patients with SSD compared to those without.

Conclusion

Our data confirms an SSD prevalence of 20% in the surgical population. This is associated with increased opioid prescription. Early recognition of SSD and implementation of appropriate treatment could reduce hospital presentations, admissions and opioid prescription. We will continue recruitment to 800 participants by March 2020.

Take-home message

SSD is common in all populations, and results in increased hospital presentations, admissions and opioid prescription. Early recognition and implementation of appropriate treatment may reduce healthcare burden, improve patient outcomes, and reduce opioid prescription.

Psychiatric impact of mobile usage on medical student life: Ringxiety, nomophobia, and sleep

Introduction

The usage of mobile phones has seen exponential growth worldwide.^1,2 While college students use mobile applications for educational purposes, the reports of adverse health problems are emerging.^3,4

Objectives

Investigate the impact of mobile usage patterns on the life of medical students and its association with psychiatric effects concerning ringxiety and nomophobia.

Methods

Data was collected from the 300 medical students of Ashwini Rural Medical College of India through a survey for this cross-sectional study. Chi-square (χ2) was used for statistics that revealed association, mobile phone usage patterns, including time spent before sleep, in classrooms or clinics, and frequency of update checks.

Results

A significant association was found between time spent on mobile before sleep and duration of sleep, and mobile usage in classrooms or clinics and psychological effects (p<0.0001). Significant association observed between mobile use in classes or clinics and the frequency of update checks, and the frequency of update checks and psychological effects (p<0.0001). About 78% of participants distracted in self-study due to mobile. Updates checked every 10 minutes by 14.7%, every hourly by 43%, and during breaks by 42.3%. Mobile low network caused anxiety (13.3%) and irritability (67.3%). About 41.7% of students couldn’t abstain from mobile use for a day. Every student used the mobile phone averagely for 24 minutes before they went to sleep.

Conclusions

Our study results highlight the prevalence of ringxiety and nomophobia in medical school students. With the surging dependency on mobile phones and technology, we need to cautiously monitor its adverse effects on psychology and psychiatric conditions.

Impact of “national suicide prevention week” on digital awareness of suicide prevention : an insight from google trends

Introduction

Every year in the month of September, National Suicide Prevention Week is celebrated. The goal of suicide prevention week is to inform the public about suicide prevention, primarily the warning signs of suicide. However, the impact of this month on the general population is unknown. The Google trends show how frequent web searches have been performed for a particular search-term, which provide an approximation of the people’s interest.

Objectives

To evaluate public interest in suicide prevention by analyzing the google trends of “Suicide Prevention” search-term.

Methods

We estimated the interest in such topics by running the google trends data of the last decade by using the filter [Search Term:“Suicide Prevention”, Locations: “United States” and Time Ranges “ 2010 to 2020”].

Results

During this specific interval, people have searched “Suicide Prevention” most frequently during the month of September (month of National Suicide Prevention week). Conversely, in the other months, interest in “suicide prevention” fluctuated between little to none. The only other time people have shown interest in Suicide prevention, other than the month of September, was with suicide news in the media, such as the death of a celebrity by suicide, or suicide-related TV shows. [Figure]

Conclusions

Although it is not definitive, it gives some idea that National Suicide Prevention week has a considerable impact on population interest. Since we did not observe sufficient public interest in other months, there should be frequent and systematic efforts to spread suicide prevention awareness among the general population.

Barriers in managing psychiatric disorders in athletes

Introduction

Athletes have participated in sports and physical exercise for several decades as a coping strategy to alleviate mental health and behavioral issues. The increasing prevalence of psychiatric disorders among athletes attributed to the failure of its appropriate management.

Objectives

Our goal is to identify barriers in diagnosing and treating psychiatric problems among sportspersons to educate clinicians about the potential risk factors for athletes’ mental health disorders to provide optimal medical care.

Methods

We examined MeSH terms “Athletes,” “Sports,” “Risk Factors,” “Diagnosis,” and “Patient Care Management,” in the context of “Mental Health,” “Mental Disorders,” “sports psychiatry,” and “diagnostic barriers.” We included 23 studies per the PRISMA guidelines, searching Medline, PubMed, PubMed Central, and PsychInfo databases until August 2020.

Results

Barriers managing psychiatric disorders in athletes are overtraining syndrome, compensatory training, idolizing, negative coping mechanisms, social stigma, injuries, and performance-enhancing supplements usage. Other factors attributed to diagnostic barriers are general perceptions, age, racial and gender disparities, poor health services, interpersonal issues, patient-therapist relationships, sense of entitlement, control or confidentiality problems, and lack of quality preventative measures. Risk factors are injuries, sports type, doping, substance abuse, lifestyle, failures in achievement, eating disorders, and maladaptive coping mechanisms.

Conclusions

These barriers in psychiatric care have adversely impacted the mental health of sportspersons. Athletes have deviated from their careers and lost valuable periods of their lives due to inadequate attention to sports psychiatry aspects, such as cognitive health services, inclusive sports management measures, diagnostic and treatment approaches, reliable mental health services, and public awareness programs.

Mental health impact of covid on athletes

Introduction

The coronavirus pandemic continues to impact all aspects of the daily life of the public worldwide. With decreased economic activity, the sports industry faces significant challenges of maintaining athletes’ mental health while seeking the best strategies for eventual return to sports competition.

Objectives

We aim to evaluate COVID-19 related factors impacting on the mental health of athletes and provide appropriate management steps.

Methods

We examined MeSH terms “Athletes,” “Sports,” “COVID-19,” in the context of “Mental Health,” “Mental Disorders,” “Behavioral Medicine,” “Risk Factors.” We identified seven studies for the qualitative synthesis per the PRISMA guidelines, searching Medline, PubMed, PubMed Central, and PsychInfo databases until July 2020.

Results

The pandemic has negatively impacted athletes’ mental wellbeing due to decreased physical activities, limited resources, fears, and delays or cancellations of the sporting event. The negative psychological impact on athletes is due to self-isolation measures leading to worries of less preparedness for the lockdown, reduced physical activity, loss of competitive advantages, fear of being infected, social isolation, and loneliness. During this period, athletes struggled to maintain baseline routine and engaged in excessive calorie intake, eating low-quality food, substance use, and sleep disruption. It has caused anxiety, depression, PTSD, and mood disorder at varying degrees of severity in athletes.

Conclusions

Limited resources during a pandemic have caused adverse mental impact on athletes. We recommend improving physical activity through confined or virtual training programs with colleagues. A collaborative approach is required by clinicians, psychologists, coaches, sports organizations, government bodies to limit the pandemic’s mental health impact.

Mood disorders and suicides during coronavirus pandemic

Introduction

The outbreak of COVID-19 has disrupted the lives of countless people worldwide. The pandemic has imposed a sense of uncertainty and anxiety, as the world could not predict or prepare for this crisis. It is important to study risk factors, including employment, marital status, and pre-existing medical or psychiatric conditions to effectively handle this pandemic’s mental health impact.

Objectives

We aim to evaluate factors contributing to the suicides and mood disorders during the coronavirus pandemic.

Methods

We examined MeSH terms “COVID-19” in the context of “Mood Disorders,” “Suicide,” “Suicidal Ideation,” “Assisted or Suicide, Attempted or Suicide,” “Risk Factors.” We identified eight case studies for the qualitative synthesis per the PRISMA guidelines, searching Medline, PubMed, PubMed Central, and PsychInfo databases until August 2020.

Results

We identified that the population of all age groups and sex are at risk of stress and mental illness due to the pandemic. Several factors are attributed to the increased risk of mood disorders and suicide. Not having pre-existing psychiatric or medical condition is not a protective factor, since suicide was attempted or committed due to external factors such as economic and social.

Conclusions

The pandemic has increased the risk of mood disorder and suicides in the population. Focus should be on the behavioral and psychological first aid to curb stress.

89 Improving Pain Assessment and Management for Patients with Cognitive Impairment on the Care of the Older Person (COOP) Wards

Introduction

Patients with cognitive impairment are at risk of underassessment and inadequate management of pain. Self-reporting is unlikely to be a reliable indicator of pain and numerical scales have reduced validity, hence an alternative assessment tool must be used. The Abbey Pain Scale is widely regarded to be user friendly. Regular analgesia should be used for these patients where possible instead of “as required” (PRN). Using QIP methodology, we aimed to improve the use of the Abbey Pain Scale for assessment of patients with cognitive impairment and better analgesia prescribing.

Methods

Audit of patient records on COOP wards (computer and physical notes, n = 48 first cycle, n = 32 second cycle) before and after staff training, assessing patients with cognitive impairment for: use of Abbey Pain Scale; use of regular paracetamol; pain assessments documented by different healthcare professionals.

Results

In the first cycle, 16 patients had cognitive impairment: only 1 of these patients (6%) was assessed using the Abbey Pain Scale. Group teaching for the multidisciplinary team on pain assessments was undertaken with practice development nurses. In the re-audit, 13 patients had cognitive impairment and 6 of these (46%) were assessed using the Abbey Pain Scale, showing a clear improvement following staff training. The second cycle showed a 50% increase in the prescription of regular paracetamol for patients with cognitive impairment. There was also a 2.5-fold improvement in therapy staff documenting pain assessments between the two audits.

Conclusions

Staff training in the use of the Abbey Pain Scale led to an almost 8-fold increase in its use for patients with cognitive impairment. Training on the use of the Abbey Pain Scale should be regularly provided to nurses, physiotherapists and doctors on the care of the older person wards.

Fuzzy fractional-order model of the novel coronavirus

In this paper, a novel coronavirus infection system with a fuzzy fractional differential equation defined in Caputo's sense is developed. By using the fuzzy Laplace method coupled with Adomian decomposition transform, numerical results are obtained for better understanding of the dynamical structures of the physical behavior of COVID-19. Such behavior on the general properties of RNA in COVID-19 is also investigated for the governing model. The results demonstrate the efficiency of the proposed approach to address the uncertainty condition in the pandemic situation.

0869 Slow Wave Sleep Is Associated With Decreased Risk Of Gestational Diabetes Mellitus

Introduction

Pregnancy is associated with disrupted slow-wave sleep (SWS) and a high prevalence of sleep disordered breathing (SDB), which may further exacerbate the decrease of deep sleep. Reduced slow wave sleep may impair glucose homeostasis, contributing to Gestational Diabetes Mellitus (GDM). Studies investigating EEG markers of deep and light sleep, and their associations with SDB and GDM are lacking. In this study, we measured associations of EEG Delta-power with objective SDB measures assessed in late-pregnancy to determine if changes in these bands are associated with GDM risk.

Methods

74 women (24-36 weeks pregnancy) underwent overnight polysomnography. Spectral profiles for Delta relative power were created for NREM and REM sleep after removing epochs with movements or muscle artifacts. The association of Delta power with SDB, assessed by the Apnea Hypopnea-Index (AHI) and AHI-based SDB severity (none, mild, moderate, severe) was tested by multivariate linear regression including demographic variables with bivariate correlations (p&lt;0.2) versus Delta-power. Conditional-regression was used to explore relationships between Delta-power and GDM, controlling for covariates.

Results

Obstructive Sleep Apnea (OSA, AHI&gt;5) was present in 14% of subjects (8 GDM-cases and 3 controls). In bivariate analyses, AHI, AHI-severity categories and OSA were associated with Delta-power in NREM (all p&lt;0.2) and AHI was associated with Delta relative-power in REM (p=0.18). However, these associations did not remain significant after adjusting for covariates. Delta relative-power in NREM was significantly associated with decreased risk of GDM (OR:0.50, 95%CI-0.25,0.91), but, in REM sleep, was not associated with GDM risk (OR:1.25, 95%CI-0.79,1.97).

Conclusion

These analyses failed to demonstrate an association between OSA or OSA severity and EEG Delta power. However, lower levels of SWS, characterized by low Delta power were associated with increased GDM risk.
