Development, validation and clinical utility of short-term adverse-effects of electroconvulsive therapy (SAVE) checklist

Electroconvulsive therapy (ECT) is one of the most effective treatments in psychiatry. However, it has many cognitive and non-cognitive adverse effects (AEs). There are lacunae in the literature on systematic assessment of non-cognitive AEs. There is a need for a standard, comprehensive and specific clinical tool to evaluate this. Hence, a checklist of short-term AEs of ECT (SAVE) with a 2-phase assessment was developed. Content validation was done using 15 experts' ratings and predefined content validity ratio and index (CVR and CVI) in a two-stage modified Delphi method. The checklist had a good CVR and CVI with a final tool of 39 items. The tool was sensitive and identified the non-cognitive AEs after ECT. Cardiovascular and musculoskeletal systems displayed the highest incidence. Many participants exhibited delayed recovery in orientation, gait, and stance, highlighting a necessity for meticulous monitoring. SAVE is the first standardised tool to assess short-term ECT-related AEs systematically. This checklist likely identifies clinically significant incidences of adverse effects. Its regular use may enhance the safety of ECT and patient comfort by supporting early identification and intervention for AEs. However, given the transient nature of AEs, further studies are needed to determine their predictive validity for long-term consequences.

Standards for medical devices: Electroconvulsive therapy machine

The manuscript calls for establishing a standard for electroconvulsive devices by manufacturers for better regulation in India. This is most relevant in the context of two recent developments, (a) Notification of medical devices rules, 2017 with classification of ECT as Class C and (b) Recent change in classification of ECT devices by US-FDA in 2018. The establishment of standards would help in upregulating the standard of ECT devices as well as ECT practices.

Dose response of transcranial near infrared light stimulation on brain functional connectivity and cognition in older adults-A randomized comparison

Photobiomodulation, also called low-level light therapy, has been reported in animal studies to have an effect on brain activity and cognition. However, studies in humans regarding its effect on cognition and brain functional connectivity, and the required dose threshold for achieving the same have been very limited. We compared the effects of different doses of photobiomodulation (PBM) on cognition and resting state brain functional connectivity in 25 cognitively normal adults aged 55-70 years. They were randomized to a single session of the sham group, "low-dose" and "high-dose" groups receiving NIR light with transcranial fluence of 26 and 52 J/cm2 respectively, and intranasal fluence of 9 and 18 J/cm2 respectively. There was a significant increase in resting state functional connectivity of the left superior frontal gyrus (SFG) with the left planum temporale (PT), p = 0.0016, and with the left inferior frontal gyrus, pars triangularis, p = 0.0235 in the "high-dose" group only compared to the "sham" group. There was also a significant improvement in visual search and processing speed (p = 0.012) in the "high-dose" group. Replication of these findings in an adequately powered randomized sham-controlled study in healthy older adults can pave the way for clinical application of NIRL as a therapeutic modality in patients with Alzheimer's disease.

Pneumatic elastostatics of multi-functional inflatable lattices: realization of extreme specific stiffness with active modulation and deployability

As a consequence of intense investigation on possible topologies of periodic lattices, the limit of specific elastic moduli that can be achieved solely through unit cell-level geometries in artificially engineered lattice-based materials has reached a point of saturation. There exists a robust rationale to involve more elementary-level mechanics for pushing such boundaries further to develop extreme lightweight multi-functional materials with adequate stiffness. We propose a novel class of inflatable lattice materials where the global-level stiffness can be derived based on a fundamentally different mechanics compared with conventional lattices having beam-like solid members, leading to extreme specific stiffness due to the presence of air in most of the lattice volume. Furthermore, such inflatable lattices would add multi-functionality in terms of on-demand performances such as compact storing, portability and deployment along with active stiffness modulation as a function of air pressure. We have developed an efficient unit cell-based analytical approach therein to characterize the effective elastic properties including the effect of non-rigid joints. The proposed inflatable lattices would open new frontiers in engineered materials and structures that will find critical applications in a range of technologically demanding industries such as aircraft structures, defence, soft robotics, space technologies, biomedical and various other mechanical systems.

Hyperon Polarization along the Beam Direction Relative to the Second and Third Harmonic Event Planes in Isobar Collisions at sqrt[s_{NN}]=200 GeV

The polarization of Λ and Λ[over ¯] hyperons along the beam direction has been measured relative to the second and third harmonic event planes in isobar Ru+Ru and Zr+Zr collisions at sqrt[s_{NN}]=200  GeV. This is the first experimental evidence of the hyperon polarization by the triangular flow originating from the initial density fluctuations. The amplitudes of the sine modulation for the second and third harmonic results are comparable in magnitude, increase from central to peripheral collisions, and show a mild p_{T} dependence. The azimuthal angle dependence of the polarization follows the vorticity pattern expected due to elliptic and triangular anisotropic flow, and qualitatively disagrees with most hydrodynamic model calculations based on thermal vorticity and shear induced contributions. The model results based on one of existing implementations of the shear contribution lead to a correct azimuthal angle dependence, but predict centrality and p_{T} dependence that still disagree with experimental measurements. Thus, our results provide stringent constraints on the thermal vorticity and shear-induced contributions to hyperon polarization. Comparison to previous measurements at RHIC and the LHC for the second-order harmonic results shows little dependence on the collision system size and collision energy.

Empathic Accuracy Task: Indian Adaptation and Validation

Background

The Empathic Accuracy Task (EAT) is an objective measure to assess empathic accuracy. Due to the variability in the number and linked emotions of the narrated events, we adapted EAT for the Indian sociocultural setting as Indian EAT (I-EAT).

Methods

Eight videos were adapted in three languages (English, Hindi, and Kannada), narrating emotional events with a uniform representation of age groups, different emotions, and sex. The adapted I-EAT was then validated by cross-sectional comparison with different tests similar to EAT and those that assessed concepts different from or similar to empathy, in 29 healthy young adults, 23 healthy older adults (aged ≥60 years) along with clinical groups of 15 young people with depression, 15 older people with depression, and 15 young people with schizophrenia.

Results

We selected eight videos with good content validity and internal consistency (Cronbach's alpha = 0.73. We obtained satisfactory concurrent validity of the EAT scores with the self-reported empathic assessments using the Questionnaire of Cognitive and Affective Empathy (Cognitive empathy score = 0.29, p = .034; Total score = 0.29, p = .035) and Interpersonal Reactivity Index (Empathic concern score = 0.45, p = .001). Good divergent validity was revealed in the high inverse correlation recorded with the Apathy Evaluation Scale ( = -0.67, p < .001). I-EAT did not correlate significantly with measures of social cognition. Known-groups validity was adequate in young adults with the significantly lower EAT scores (Cohen's d: 0.77 to 1.15) in the Schizophrenia group and higher EAT-N scores (Cohen's d: 0.51) in the Depression group, compared to the Healthy group. The Healthy group of the geriatric population also achieved significantly higher EAT scores (Cohen's d: 0.71 to 0.85) than the Depression group.

Conclusion

With a good validity and internal consistency, I-EAT can be used in the Indian population to assess empathic accuracy without compromising performance of the original EAT.

A micro-costing analysis of nutritional support for persons with TB and their families in India

Undernutrition is the leading risk factor for TB infection and death in India. We undertook a micro-costing analysis of a nutritional intervention for household contacts of people living with TB in Puducherry, India. We found that the total 6-month food cost for a family of four was USD4/day. We also identified several alternative regimens and cost-lowering strategies to encourage wider adoption of nutritional supplementation as a public health tool.

Measurements of the Elliptic and Triangular Azimuthal Anisotropies in Central ^{3}He+Au, d+Au and p+Au Collisions at sqrt[s_{NN}]=200 GeV

The elliptic (v_{2}) and triangular (v_{3}) azimuthal anisotropy coefficients in central ^{3}He+Au, d+Au, and p+Au collisions at sqrt[s_{NN}]=200  GeV are measured as a function of transverse momentum (p_{T}) at midrapidity (|η|<0.9), via the azimuthal angular correlation between two particles both at |η|<0.9. While the v_{2}(p_{T}) values depend on the colliding systems, the v_{3}(p_{T}) values are system independent within the uncertainties, suggesting an influence on eccentricity from subnucleonic fluctuations in these small-sized systems. These results also provide stringent constraints for the hydrodynamic modeling of these systems.

Observation of Directed Flow of Hypernuclei _{Λ}^{3}H and _{Λ}^{4}H in sqrt[s_{NN}]=3 GeV Au+Au Collisions at RHIC

We report here the first observation of directed flow (v_{1}) of the hypernuclei _{Λ}^{3}H and _{Λ}^{4}H in mid-central Au+Au collisions at sqrt[s_{NN}]=3  GeV at RHIC. These data are taken as part of the beam energy scan program carried out by the STAR experiment. From 165×10^{6} events in 5%-40% centrality, about 8400 _{Λ}^{3}H and 5200 _{Λ}^{4}H candidates are reconstructed through two- and three-body decay channels. We observe that these hypernuclei exhibit significant directed flow. Comparing to that of light nuclei, it is found that the midrapidity v_{1} slopes of _{Λ}^{3}H and _{Λ}^{4}H follow baryon number scaling, implying that the coalescence is the dominant mechanism for these hypernuclei production in the 3 GeV Au+Au collisions.

Beam Energy Dependence of Triton Production and Yield Ratio (N_{t}×N_{p}/N_{d}^{2}) in Au+Au Collisions at RHIC

We report the triton (t) production in midrapidity (|y|<0.5) Au+Au collisions at sqrt[s_{NN}]=7.7-200  GeV measured by the STAR experiment from the first phase of the beam energy scan at the Relativistic Heavy Ion Collider. The nuclear compound yield ratio (N_{t}×N_{p}/N_{d}^{2}), which is predicted to be sensitive to the fluctuation of local neutron density, is observed to decrease monotonically with increasing charged-particle multiplicity (dN_{ch}/dη) and follows a scaling behavior. The dN_{ch}/dη dependence of the yield ratio is compared to calculations from coalescence and thermal models. Enhancements in the yield ratios relative to the coalescence baseline are observed in the 0%-10% most central collisions at 19.6 and 27 GeV, with a significance of 2.3σ and 3.4σ, respectively, giving a combined significance of 4.1σ. The enhancements are not observed in peripheral collisions or model calculations without critical fluctuation, and decreases with a smaller p_{T} acceptance. The physics implications of these results on the QCD phase structure and the production mechanism of light nuclei in heavy-ion collisions are discussed.

Measurement of Sequential ϒ Suppression in Au+Au Collisions at sqrt[s_{NN}]=200 GeV with the STAR Experiment

We report on measurements of sequential ϒ suppression in Au+Au collisions at sqrt[s_{NN}]=200  GeV with the STAR detector at the Relativistic Heavy Ion Collider (RHIC) through both the dielectron and dimuon decay channels. In the 0%-60% centrality class, the nuclear modification factors (R_{AA}), which quantify the level of yield suppression in heavy-ion collisions compared to p+p collisions, for ϒ(1S) and ϒ(2S) are 0.40±0.03(stat)±0.03(sys)±0.09(norm) and 0.26±0.08(stat)±0.02(sys)±0.06(norm), respectively, while the upper limit of the ϒ(3S) R_{AA} is 0.17 at a 95% confidence level. This provides experimental evidence that the ϒ(3S) is significantly more suppressed than the ϒ(1S) at RHIC. The level of suppression for ϒ(1S) is comparable to that observed at the much higher collision energy at the Large Hadron Collider. These results point to the creation of a medium at RHIC whose temperature is sufficiently high to strongly suppress excited ϒ states.

Beam Energy Dependence of Fifth- and Sixth-Order Net-Proton Number Fluctuations in Au+Au Collisions at RHIC

We report the beam energy and collision centrality dependence of fifth and sixth order cumulants (C_{5}, C_{6}) and factorial cumulants (κ_{5}, κ_{6}) of net-proton and proton number distributions, from center-of-mass energy (sqrt[s_{NN}]) 3 GeV to 200 GeV Au+Au collisions at RHIC. Cumulant ratios of net-proton (taken as proxy for net-baryon) distributions generally follow the hierarchy expected from QCD thermodynamics, except for the case of collisions at 3 GeV. The measured values of C_{6}/C_{2} for 0%-40% centrality collisions show progressively negative trend with decreasing energy, while it is positive for the lowest energy studied. These observed negative signs are consistent with QCD calculations (for baryon chemical potential, μ_{B}≤110  MeV) which contains the crossover transition range. In addition, for energies above 7.7 GeV, the measured proton κ_{n}, within uncertainties, does not support the two-component (Poisson+binomial) shape of proton number distributions that would be expected from a first-order phase transition. Taken in combination, the hyperorder proton number fluctuations suggest that the structure of QCD matter at high baryon density, μ_{B}∼750  MeV at sqrt[s_{NN}]=3  GeV is starkly different from those at vanishing μ_{B}∼24  MeV at sqrt[s_{NN}]=200  GeV and higher collision energies.

Deep phenotyping and genomic data from a nationally representative study on dementia in India

The Harmonized Diagnostic Assessment of Dementia for the Longitudinal Aging Study in India (LASI-DAD) is a nationally representative in-depth study of cognitive aging and dementia. We present a publicly available dataset of harmonized cognitive measures of 4,096 adults 60 years of age and older in India, collected across 18 states and union territories. Blood samples were obtained to carry out whole blood and serum-based assays. Results are included in a venous blood specimen datafile that can be linked to the Harmonized LASI-DAD dataset. A global screening array of 960 LASI-DAD respondents is also publicly available for download, in addition to neuroimaging data on 137 LASI-DAD participants. Altogether, these datasets provide comprehensive information on older adults in India that allow researchers to further understand risk factors associated with cognitive impairment and dementia.

Indian Psychiatric Society multicentre study: Diagnostic patterns, comorbidity and prescription practices for patients with Dementia

BACKGROUND

There are more than 5 million people with dementia in India. Multicentre studies looking at details of treatment for people with dementia In India are lacking. Clinical audit is a quality improvement process which aims to systematically assess, evaluate, and improve patient care. Evaluating current practice is the key to a clinical audit cycle.

AIM

This study aimed to assess the diagnostic patterns and prescribing practices of psychiatrists for patients with dementia in India.

METHOD

A retrospective case file study was conducted across several centers in India.

RESULTS

Information from the case records of 586 patients with dementia was obtained. Mean age of the patients was 71.14 years (standard deviation = 9.42). Three hundred twenty one (54.8%) were men. Alzheimer's disease (349; 59.6%) was the most frequent diagnosis followed by vascular dementia (117; 20%). Three hundred fifty five (60.6%) patients had medical disorders and 47.4% patients were taking medications for their medical conditions. Eighty one (69.2%) patients with vascular dementia had cardiovascular problems. Majority of the patients (524; 89.4%) were on medications for dementia. Most frequently prescribed treatment was Donepezil (230; 39.2%) followed by Donepezil-Memantine combination (225; 38.4%). Overall, 380 (64.8%) patients were on antipsychotics. Quetiapine (213, 36.3%) was the most frequently used antipsychotic. Overall, 113 (19.3%) patients were on antidepressants, 80 (13.7%) patients were on sedatives/hypnotics, and 16 (2.7%) patients were on mood stabilizers. Three hundred nineteen (55.4%) patients and caregivers of 374 (65%) patients were receiving psychosocial interventions.

CONCLUSIONS

Diagnostic and prescription patterns in dementia which emerged from this study are comparable to other studies both nationally and internationally. Comparing current practices at individual and national levels against accepted guidelines, obtaining feedback, identifying gaps and instituting remedial measures help to improve the standard of care provided.

Clinical efficacy and neurobiological correlates of electroconvulsive therapy in patients with clozapine-resistant/intolerant schizophrenia: study protocol of multi-site parallel arm double-blind randomized sham-controlled study

Background: A substantial proportion of patients with treatment resistant schizophrenia do not respond well or partially to clozapine, with a subset that does not tolerate an adequate trial of clozapine. Electroconvulsive therapy (ECT) is regarded as one of the augmenting options, but there is a lack of high-quality evidence for this practice. This protocol describes a double-blind randomised sham-controlled modified-ECT trial to evaluate its efficacy in patients with clozapine resistant/intolerant schizophrenia. The study also involves multimodal investigations to identify the response predictors and the mechanistic basis of modified ECT in this population. Methods: One hundred consenting schizophrenia patients with resistance/intolerance to clozapine referred by clinicians for ECT would be randomly assigned to receive true ECT or sham ECT at three study centers. Sham ECT would mimic all the procedures of modified ECT including anaesthesia and muscle relaxation, except the electrical stimulation. After a blinded course, non-responders to sham ECT would be offered open-label true ECT. Clinical assessments, neurocognitive assessments and multimodal investigations (magnetic resonance imaging [MRI], electroencephalography, heart rate variability, investigative transcranial magnetic stimulation-transcranial direct current stimulation, gene polymorphism) would be conducted at baseline and repeated after the end of the trial, as well as open-label ECT course. The trial would evaluate the improvement in positive symptoms (scale for assessment of positive symptoms) of schizophrenia as the primary outcome measure with prediction of this change by resting-state functional-MRI based brain-connectivity as the second primary objective.

Study protocol for evaluating the clinical efficacy and neurobiological correlates of sequential treatment with tDCS primed iTBS and ECT in treatment-resistant depression

Background: Treatment-resistant depression is a burdensome condition. Intermittent theta burst stimulation (iTBS) of the left dorsolateral prefrontal cortex is considered a treatment option in early course of resistance with a proportion of such patients responding to it. Preliminary evidence suggests a role of priming iTBS stimulation with preconditioning using cathodal transcranial direct current stimulation (tDCS). This protocol describes a double-blind randomized sham-controlled study to evaluate the clinical efficacy and tolerability of tDCS-primed iTBS in the treatment of resistant depression. Non-responders to this trial will be offered open-label electroconvulsive therapy. All participants will undergo neurobiological investigations that will enable the identification of potential response predictors and mechanisms. Methods: Three hundred and fifty consenting patients with treatment resistant depression will be randomly assigned to receive 20–30 daily sessions of true-tDCS or sham-tDCS primed iTBS over left dorsolateral prefrontal cortex at three study centers. After this blinded sham-controlled trial, non-responders to the intervention will be offered open-label true ECT. Clinical assessments, neurocognitive assessments and multimodal investigations (magnetic resonance imaging, electroencephalography, heart rate variability, investigative transcranial magnetic stimulation-transcranial direct current stimulation, gene polymorphisms) will be conducted at baseline and repeated after the end of the trial, as well as open-label ECT course. The trial will evaluate the improvement in depressive symptoms (Hamilton depression rating scale) between the two groups as the primary outcome measure.

Impact of structured physical activity program on the level of functional ability of Persons with Mental Illness

BACKGROUND

A structured physical activity program has many health benefits. Physical activity improves the functional ability of a patient with mental illness as an adjunctive treatment. This study aimed to evaluate the efficacy of a physical activity program on the level of functional ability of patients with mental illness.

MATERIALS AND METHODS

A pre-experimental research design and one group pre-post design were adopted. Thirty-one in-patients with mental illness who met the inclusion criteria were recruited for the study using convenient sampling. Baseline data were collected using sociodemographic and illness profiles developed by the researcher and validated by the experts. Functional ability and illness severity were assessed using the standardized World Health Organization Disability Assessment Schedule (WHODAS) (36-item version) and the Clinical Global Improvement Scale. Pretest, i.e., intervention with structured physical activity, was administered for 40 consecutive days. A posttest was given 30 days after the intervention ended to assess the impact of the structured physical activity program on the level of functional ability among the study participants.

RESULTS

The impact of structured physical activity on functional ability was measured using the WHODAS 2.0, a 36-item version. The paired Sample t-test and the Wilcoxon Rank test analyzed the data. There was a significant improvement in the overall functional ability of study participants at P = 0. 001.

CONCLUSION

The study findings support that structured physical activity substantially impacts functional ability among patients with mental illnesses.

Psychotherapeutic Treatments of Trichotillomania

Introduction

Trichotillomania (TTM), also known as hair pulling disorder, is an obsessive- compulsive disorder characterized by the recurrent, overwhelming urge to repeatedly pull out one’s hair. Hair pulling can occur anywhere on the body but is most common on the scalp, eyebrows, and eyelashes and subsequently results in bald patches. While TTM is a very prevalent, debilitating disorder, there is still no FDA approved treatment that exists.

Objectives

The main objective of this study is to explore the various forms of available psychotherapy available for the treatment of trichotillomania.

Methods

Two independent reviewers conducted title, abstract, full-text searching and data extraction among the PubMed, PsycINFO, and ResearchGate data bases. Of the 79 articles screened, five were included in this review

Results

Habit reversal therapy (HRT) is a form of cognitive behavioral therapy that is considered the first line treatment for management of TTM. Other psychotherapeutic techniques include acceptance and commitment therapy, progressive muscle relaxation, and mindfulness therapy.

Conclusions

This study supports the current data which states that HRT is the first line treatment and there is yet to be a pharmacological treatment of choice for TTM. It is also very important to note that TTM is still underdiagnosed and can be mistaken for a dermatological disorder like alopecia aerata. Furthermore, many people with trichilemmoma have underlying mental health disorders such as anxiety and depression that must first be addressed before treating the hair pulling itself.

Is Thalamic Lesion a Contributing Factor for Inappropriate Sexual Behavior in Older Adults with Cognitive Impairment?

Thalamus is a group of nuclei located deep inside the brain, well known for its sensory and cognitive functions. However, its role in the reward and behavior regulation is less explored. In this case series, we have presented four cases with inappropriate sexual behaviors (ISB) that are temporally related to thalamic infarction. We have discussed about the limbic part of thalamus and its extensive connections with other regions in regulating sexual behaviors. Although in all the four cases described there was underlying cognitive impairment that can itself increase the risk of ISB, there was potential contributing role of thalamic lesions.

Reflected image processing abnormalities in dementia - a case series and review

Dementia is a neurodegenerative condition with progressive decline in cognitive faculties and associated with different clinical phenomena. Mirror phenomenon in terms of both mirror agnosia and mirror image agnosia wherein there is difficulty in processing and perception of reflected images is not uncommonly seen, and understanding the same can contribute to early diagnosis and prognostication. We report two elderly women with Alzheimer's dementia and frontotemporal dementia, respectively, presenting with features of abnormalities in mirror image processing. The former had features of both mirror agnosia and mirror image agnosia and the latter had predominantly features of mirror image agnosia with preoccupation with her mirror image. Understanding neuroanatomical networks underlying these phenomena can help early identification and subtyping dementia. Clinically differentiating these phenomena from psychotic symptoms of dementia can help in initiating appropriate non-pharmacological measures rather than resorting to use of psychotropics, the use of which may be counterproductive.

Probing the Gluonic Structure of the Deuteron with J/ψ Photoproduction in d+Au Ultraperipheral Collisions

Understanding gluon density distributions and how they are modified in nuclei are among the most important goals in nuclear physics. In recent years, diffractive vector meson production measured in ultraperipheral collisions (UPCs) at heavy-ion colliders has provided a new tool for probing the gluon density. In this Letter, we report the first measurement of J/ψ photoproduction off the deuteron in UPCs at the center-of-mass energy sqrt[s_{NN}]=200  GeV in d+Au collisions. The differential cross section as a function of momentum transfer -t is measured. In addition, data with a neutron tagged in the deuteron-going zero-degree calorimeter is investigated for the first time, which is found to be consistent with the expectation of incoherent diffractive scattering at low momentum transfer. Theoretical predictions based on the color glass condensate saturation model and the leading twist approximation nuclear shadowing model are compared with the data quantitatively. A better agreement with the saturation model has been observed. With the current measurement, the results are found to be directly sensitive to the gluon density distribution of the deuteron and the deuteron breakup process, which provides insights into the nuclear gluonic structure.

An overview of orthodontic malpractice liability based on a survey and case assessment review

Background

The purpose of this survey study and case review was to identify 1) the common causes related to filing a malpractice claim against an orthodontist and, 2) the factors mitigating against a potential malpractice claim in the United States (U.S). The objectives of the case review were to examine the current state of orthodontic malpractice litigation from a cause and mitigating point of view.

Material and Methods

Data for this research was collected and reviewed using the following two methods: 1) A survey questionnaire on aspects of malpractice liability was electronically distributed to 2,241 active U.S. members of the American Association of Orthodontists (AAO). 2) Legal cases were reviewed on the online legal research database Lexis Advance Research, and 35 cases were analyzed.

Results

Survey questionnaire results and legal case review results are as follows: 1) 77 orthodontists completed the survey. 9.1% of the respondents reported a malpractice claim having been filed against them with periodontal issues accounting for most of the claims. Survey participants reported good doctor-patient communication as being the most relevant contributory factor and most relevant mitigating factor in malpractice claims. 2) Negligence is the main reason patients sue a doctor for clinically related litigation, and failure to obtain a proper informed consent from the patient is the main cause of action for non-clinically related litigation.

Conclusions

Most respondents reported doctor-patient communication, periodontal issues, and a lack of informed consent as the main triggering elements of a lawsuit, which is similar to other studies and case review analysis. Good doctor-patient rapport was ranked as being most helpful in mitigating a potential claim, which is also similar to other studies. Another aspect of the survey questionnaire that was evaluated was whether a non-orthodontist can provide expert testimony against an orthodontist, with most respondents reporting that this is not possible. It has been ruled, though, that a general dentist can be an expert witness and provide expert testimony against an orthodontist in a lawsuit depending on the circumstances. Negligence was the most common cause of clinically related orthodontic litigation, and a failure of the practitioner to obtain a proper informed consent from the patient was the most common cause of non-clinically related orthodontic litigation.

Accelerated Epigenetic Aging Mediates the Association between Vitamin D Levels and Knee Pain in Community-Dwelling Individuals

OBJECTIVES

To examine the relationship between Vitamin D status and pain intensity and disability in individuals with and without knee pain, and to examine the role of epigenetics in this relationship.

DESIGN

Cross-sectional analysis of data from the UPLOAD-2 study (Understanding Pain and Limitations in OsteoArthritic Disease-2).

PARTICIPANTS

189 individuals aged 45-65 years and older.

MEASUREMENTS

Serum Vitamin D levels, pain related interference and characteristic pain intensity measures, and the epigenetic clock GrimAge derived from blood analyses.

RESULTS

Lower Vitamin D was associated with advanced epigenetic aging (AgeAccelGrim), greater pain and disability and that (AgeAccelGrim) mediated the relationship between Vitamin D status and self-reported pain (ab = -0.0799; CI [-0.1492, -0.0237]) and disability (ab = -0.0669; CI [-0.1365, -0.0149]) outcomes.

CONCLUSION

These data support the notion that lifestyle factors such as nutrition status play a key role in aging process, as well as the development and maintenance of age-related diseases such as pain. Modifying nutrition status could help promote healthy aging and reduce pain.

Extension for Community Healthcare Outcomes Based Telementoring of Physicians for Dementia-Effectiveness in India

OBJECTIVE

The study aimed to evaluate the effectiveness of a program based on the telementoring model [Extension for Community Healthcare Outcomes (ECHO)] for primary care physicians in diagnosing and treating patients with dementia.

METHOD

The ECHO model was adapted through 12 live sessions of 2 h every 2 weeks consisting of a didactic presentation by the expert, peer-led new case discussions, and follow-up discussions. In addition, there were 10 h of self-paced e-learning and interim assignments. The impact was examined by noting participation, session ratings, monthly clinical reports, and comparing knowledge and competency scores before and after the course.

RESULTS

Among the 63 participants, 39.7% attended at least 80% of the sessions; completing the program successfully. The ratings for all sessions ranged from "good" to "excellent." The paired sample t-test revealed a statistically significant improvement (p < 0.001) in self-rated skills and confidence in diagnosing and treating dementia with an effect size of 1.25 and 1.37, respectively. No change in the knowledge score was observed throughout the course. A considerable increase in dementia-related clinical practice was observed during four monthly summary of clinical cases. Due to the limited data of monthly reports during the COVID pandemic, no statistical analysis was attempted.

CONCLUSION

The ECHO model appears to have a positive immediate impact on the clinical ability of primary care physicians to diagnose and treat dementia. Its direct impact on patient health and at the community level should be aimed at in future studies.

Plasma neurofilament L to amyloid β42 ratio in differentiating Alzheimer's type from non-Alzheimer's dementia: A cross-sectional pilot study from India

Based on the reduction of amyloid β plaques, US FDA has recently approved Aducanumab as a disease modifying treatment for Alzheimer's disease (AD). With high pricing and the potential risks likely with this treatment, certainty of AD diagnosis becomes crucial. The current pilot study evaluated plasma levels of neurofilament L, an axonal injury marker and amyloid β42, a major component of amyloid plaques for discriminating AD from non-AD dementia (NAD). Results with Simoa assays indicate that a combination of neurofilament L and amyloid β42 can be considered as a screening tool in identifying eligible subjects for AD treatment/ clinical trials.

1534 A rare operation: resection of a complex malignant peripheral nerve sheath tumour deemed inoperable by a national centre

We present this rare case which was led by spinal surgeons at Leeds after being deemed not suitable for operative input by a national centre.

A 54-year-old lady who presented with 2-month history of worsening left flank pain on a background of four years. She was otherwise fit and well. CT confirmed aggressive left-sided paraspinal tumour with epidural encroachment, extending from T8 to T10 vertebral levels. Its deep surface was well-defined and extending superficially through the chest wall with destruction of ribs. The mass grew in size in course of days requiring urgent attention due to risk of cord compression. Biopsy proved high grade MPNST.

Malignant peripheral nerve sheath tumor (MPNST) is a rare type of sarcoma, 5-10% of sarcoma cases. MPNST is most common in young adults and middle-aged adults. About 25% to 50% of people with MPNST have NF1. 8% to 13% of people with NF1 will get MPNST in their lifetime.

An MDT approach involving spinal, thoracic, vascular and plastic surgeons opined it requiring extensive surgery due to its complexity. It was performed in stages – embolisation then aortic stent placement followed by final resection of the tumour with chest well reconstruction using an LD flap.

A multidisciplinary and multispecialty approach has led to a positive prognosis for this patient who is on the road to recovery.

Future-Proofing Geriatric Mental Health Care Services in India: Training and Policy Directions

BACKGROUND

A burgeoning rise in the elderly subpopulation is being noted in India. This rise has already earned the designation as a shining nation by the United Nations/World Health Organization. This growth will take the elderly subpopulation to 324 million persons above 60 years by 2050. The mental health needs of this subpopulation are varied and nuanced compared to that of the general population. The risk and prevalence of mental health morbidity are also greater. There is an urgent need to gear up the health care systems.

CONSIDERATIONS

Various aspects of the ongoing demographic transitions are considered alongside available health information. Legislative mandates and laws are also reviewed to provide context to qualify the action points and recommendations. Recommendations, India must act urgently to strengthen health care delivery systems in a concurrent multipronged approach. These efforts should focus on developing trained Human Resources and adequate infrastructural resources. Review mechanisms to inform on required updates on best practices and evidence-based medicine must also be incorporated and developed to perform periodically.

Novel major QTLs associated with low soil phosphorus tolerance identified from the Indian rice landrace, Wazuhophek

With an objective of mapping novel low soil P (Phosphorus) tolerance loci in the non-Pup1 type donor rice line, Wazuhophek, we screened a recombinant inbred line (RIL) mapping population consisting of 330 lines derived from the cross Wazuhophek x Improved Samba Mahsuri (which is highly sensitive to low soil P) in a plot with low soil P for tolerance associated traits. Molecular mapping with SSR markers revealed a total of 16 QTLs (seven major and nine minor QTLs), which are associated with low soil P tolerance related traits. Interestingly, a QTL hotspot, harbouring 10 out of 16 QTLs were identified on the short arm of chromosome 8 (flanked by the makers RM22554 and RM80005). Five major QTLs explaining phenotypic variance to an extent of 15.28%, 17.25%, 21.84%, 20.23%, and 18.50%, associated with the traits, plant height, shoot length, the number of productive tillers, panicle length and yield, respectively, were located in the hotspot. Two major QTLs located on chromosome 1, associated with the traits, total biomass and root to shoot ratio, explaining 15.44% and 15.44% phenotypic variance, respectively were also identified. Complex epistatic interactions were observed among the traits, grain yield per plant, days to 50% flowering, dry shoot weight, and P content of the seed. In-silico analysis of genomic regions flanking the major QTLs revealed the presence of key putative candidate genes, possibly associated with tolerance.

Electroconvulsive therapy services during COVID-19 pandemic

The COVID-19 pandemic has hit the electroconvulsive therapy (ECT) services hard worldwide as it is considered an elective procedure and hence has been given less importance. Other reasons include the risk of transmission of infections, lack of resources, and the scarcity of anesthesiologists due to their diversion to intensive care units to manage COVID-19 patients. However, ECT is an urgent and life-saving measure for patients diagnosed with depression and other severe mental illnesses who have suicidality, catatonia, or require a rapid therapeutic response. COVID-19 pandemic is a significant source of stress for individuals due to its impact on health, employment, and social support resulting in new-onset psychiatric illnesses and the worsening of a pre-existing disorder. Hence, a continuation of the ECT services during the COVID-19 pandemic is of paramount importance. In this narrative review, the authors from India have compiled the literature on the ECT practice during the COVID-19 pandemic related to the screening and testing protocol, necessity of personal protective equipment, modification in ECT Suite, electrical stmulus settings, and anesthesia technique modification. The authors have also shared their experiences with the ECT services provided at their institute during this pandemic. This description will help other institutes to manage the ECT services uninterruptedly and make ECT a safe procedure during the current pandemic.

Resting State Functional Connectivity of Brain With Electroconvulsive Therapy in Depression: Meta-Analysis to Understand Its Mechanisms

Introduction: Electroconvulsive therapy (ECT) is a commonly used brain stimulation treatment for treatment-resistant or severe depression. This study was planned to find the effects of ECT on brain connectivity by conducting a systematic review and coordinate-based meta-analysis of the studies performing resting state fMRI (rsfMRI) in patients with depression receiving ECT. Methods: We systematically searched the databases published up to July 31, 2020, for studies in patients having depression that compared resting-state functional connectivity (rsFC) before and after a course of pulse wave ECT. Meta-analysis was performed using the activation likelihood estimation method after extracting details about coordinates, voxel size, and method for correction of multiple comparisons corresponding to the significant clusters and the respective rsFC analysis measure with its method of extraction. Results: Among 41 articles selected for full-text review, 31 articles were included in the systematic review. Among them, 13 articles were included in the meta-analysis, and a total of 73 foci of 21 experiments were examined using activation likelihood estimation in 10 sets. Using the cluster-level interference method, one voxel-wise analysis with the measure of amplitude of low frequency fluctuations and one seed-voxel analysis with the right hippocampus showed a significant reduction (p < 0.0001) in the left cingulate gyrus (dorsal anterior cingulate cortex) and a significant increase (p < 0.0001) in the right hippocampus with the right parahippocampal gyrus, respectively. Another analysis with the studies implementing network-wise (posterior default mode network: dorsomedial prefrontal cortex) resting state functional connectivity showed a significant increase (p < 0.001) in bilateral posterior cingulate cortex. There was considerable variability as well as a few key deficits in the preprocessing and analysis of the neuroimages and the reporting of results in the included studies. Due to lesser studies, we could not do further analysis to address the neuroimaging variability and subject-related differences. Conclusion: The brain regions noted in this meta-analysis are reasonably specific and distinguished, and they had significant changes in resting state functional connectivity after a course of ECT for depression. More studies with better neuroimaging standards should be conducted in the future to confirm these results in different subgroups of depression and with varied aspects of ECT.

Prevalence of Common mental disorders in older adults: Results from the National Mental Health Survey of India

OBJECTIVE

We estimate the prevalence of common mental disorders (CMD) among older adults and compare them with that of younger adults at the national level.

METHOD

We analysed data on older adults from the National Mental Health Survey of India undertaken across 6 regions and 12 states of India during 2015-16. Multi-stage cluster sampling technique was adopted which permitted state level and subsequently pooled national estimates. Mini International NeuroPsychiatric Interview (MINI) adult version 6.0 was used for measuring psychiatric morbidity.

RESULTS

Older adults had a higher lifetime (6.93%) and current (3.53%) prevalence of depressive disorders as compared to the younger adults (4.96% and 2.54%). There was no difference in the prevalence of anxiety disorders in different agegroups. The most prevalent anxiety disorder in older adults was specific phobias (1.72%) followed by agoraphobia (1.6%). All CMD in the older population were more common in females, those living in urban metros, the unemployed, who were not currently married and those with lower household income.

DISCUSSION

These findings support planning better mental health policies and programs for older adults in India.

Anticholinergic Burden among Hospitalised Older Adults with Psychiatric Illnesses- A retrospective study

BACKGROUND

Drugs with anticholinergic properties are known to be associated with deleterious effects on cognition in older adults. There is a paucity of literature in this aspect in older adults with psychiatric disorders.

OBJECTIVE

To examine the anticholinergic cognitive burden and its predictors in hospitalised older adults having psychiatric disorders.

METHODS

Case records of older adults who sought inpatient care under the Geriatric Psychiatry Unit from January, 2019 to June, 2019 were reviewed. The anticholinergic burden was assessed with Anticholinergic Cognitive Burden (ACB) scale updated version, 2012.

RESULTS

Sample included 129 older adults with an almost equal number of males (53.48%) and females (46.52%) having a mean age of 67.84 (SD = 6.96) years. The diagnostic spectrum included depression (34.89%), dementia (31.01%), mania (10.85%), psychosis (13.95%), delirium (6.20%) and others (3.1%). 60.47% of the patients had more than one medical illness. 48.84% of the older adults had clinically relevant anticholinergic cognitive burden ( ACB score ≥ 3). Use of 3 or more psychotropic drugs (OR = 4.88), diagnosis of psychosis/ mania (OR = 7.62) and dementia/ delirium (neurocognitive disorders group) (OR = 5.17) increased the risk of ACB score ≥ 3.

CONCLUSION

Nearly half of the older adults in psychiatry in-patient setting had clinically relevant anticholinergic burden, which was associated with higher use of psychotropics. Our study highlights the importance of monitoring for anticholinergic effects of psychotropics in older adults.

Geriatric Telepsychiatry: Promoting Access to Geriatric Mental Health Care Beyond the Physical Barriers

Psychiatric illnesses are an important contributor of morbidity and mortality in older adults. There is increase in older adults with psychiatric disorders paralleling their growth in absolute numbers. This leads to challenges in mental health care and service delivery. Several barriers that exists in our community hinder older adults from receiving mental health care. Additionally, lack of adequate human resources in geriatric mental health care compounds the problem. Telemedicine, though not new in other fields of medicine, is relatively new in the practice of psychiatry in India. This is probably due to lack of clear guidelines and regulations regarding the same in India. There is a recent increase in teleconsultations in India similar to other developed countries due to ongoing COVID-19 pandemic. The recent telepsychiatry operational guidelines have made telepsychiatry a legitimate and official practice in India. Challenges specific to older adults in the form of low digital literacy, sensory issues, and cognitive impairment can be overcome by adopting telepsychiatry services in coming years. Concerns related to security and safety of telepsychiatry require further evaluation.

How much do Indians pay for tuberculosis treatment? A cost analysis

Setting

India's National Tuberculosis Elimination Programme (NTEP) covers diagnostic and therapeutic costs of TB treatment. However, persons living with TB (PLWTB) continue to experience financial distress due to direct costs (payment for testing, treatment, travel, hospitalization, and nutritional supplements) and indirect costs (lost wages, loan interest, and cost of domestic helpers).

Objective

To analyze the magnitude and pattern of TB-related costs from the perspective of Indian PLWTB.

Design

We identified relevant articles using key search terms ('tuberculosis,' 'India,' 'cost,' 'expenditures,' 'financing,' 'catastrophic' and 'out of pocket') and calculated variance-weighted mean costs.

Results

Indian patients incur substantial direct costs (mean: US$46.8). Mean indirect costs (US$666.6) constitute 93.4% of the net costs. Mean direct costs before diagnosis can be up to four-fold that of costs during treatment. Treatment in the private sector can result in costs up to six-fold higher than in government facilities. As many as one in three PLWTB in India experience catastrophic costs.

Conclusion

PLWTB in India face high direct and indirect costs. Priority interventions to realize India's goal of eliminating catastrophic costs from TB include decreasing diagnostic delays through active case finding, reducing the need for travel, improving awareness and perception of NTEP services, and ensuring sufficient reimbursement for inpatient TB care.

Electroconvulsive therapy during the COVID-19 pandemic

The COVID-19 pandemic has forced substantial changes in the practice of psychiatry, including that of electroconvulsive therapy (ECT). There is higher risk of transmission of the SARS-CoV-2 virus during ECT unless due care is taken. However, in many cases, ECT cannot be avoided. In this paper, we discuss various measures that may be adapted to reduce the risk of transmission of the virus during ECT. We also suggest certain modifications to the practice of ECT in order to achieve a balance between risks and benefits of the procedure during the pandemic.
