Background: There is growing body of evidence linking abnormal eye movements in people with multiple sclerosis (MS) to disease severity and cognition which could better detect disease progression. The objective of this study is to determine if a novel eye-tracking tool can accurately predict disease severity and cognitive status based on eye movement metrics and characterize how they evolve with progression. Methods: Persons with MS (n=132) will be followed over 4 years with clinical assessments every 6 months. Eye movements are also assessed while performing oculomotor tasks using Innodem Neurosciences’ patented eye-tracking technology. The eye movement metrics will be inputted into machine learning classifying algorithms to identify which metrics can serve as reliable Eye Movement Biomarkers (EMB) for MS progression and cognitive status. Results: There were 16 participants recruited as of January 2022 with mean age 47. 3 (SD 10.4; range 26-67), gender (12F/4M), EDSS 2.59 (SD 1.49; range 1.5-6.5), SDMT 51.4 (SD 14.1, range 24-78). With current enrollment, there is a negative correlation between EDSS and SDMT (r = -0.47) as observed in the literature. Conclusions: This trial will demonstrate the utility of EMBs for monitoring MS progression by improving physicians’ access to a reliable, non-invasive, sensitive and accessible marker of disease progression.
The recent development of new offshore projects in pre-salt deepwater fields has placed offshore loading operations as the main production outflow alternative, increasing the operational complexity and risks. Numerous dangerous situations are associated with oil offloading, such as the messenger line transfer during the mooring stage. Nowadays, this critical task is realized by launching a thin messenger cable using the pneumatic line throwing apparatus. This is a complex and slow process since the operation usually occurs with the ship opposite to the wind. This work proposes a hybrid flight methodology based on computer vision and sensor fusion techniques for autonomous unmanned aerial vehicles (UAVs). The UAV takes off from an oil rig and precisely reaches a specific point in the shuttle tanker without using expensive positioning devices and augmenting UAV’s orientation (yaw) precision since the compass can suffer from severe interference due to naval metallic structures near the vehicle. The proposed framework was tested in a realistic simulated environment considering several practical operational constraints. The results demonstrated both the robustness and efficiency of the methodology.
To develop a new caregiver-assisted pain coping skills training protocol specifically tailored for community-dwelling persons with cognitive impairment and pain, and assess its feasibility and acceptability.
Method
In Phase I, we conducted interviews with 10 patient–caregiver dyads to gather feedback about intervention content and delivery. Phase II was a single-arm pilot test to evaluate the intervention's feasibility and acceptability. Dyads in the pilot study (n = 11) completed baseline surveys, received five intervention sessions, and then completed post-intervention surveys. Analyses focused on feasibility and acceptability.
Results
Dyads responded positively to the pain coping skills presented in the interviews; their feedback was used to refine the intervention. Findings from the pilot study suggested that the intervention was feasible and acceptable. 69% of eligible dyads consented, 82% completed all five intervention sessions, and 100% completed the post-treatment assessment. Caregivers reported high satisfaction ratings. They also reported using the pain coping skills on a regular basis, and that they found most of the skills helpful and easy to use.
Significance of results
These preliminary findings suggest that a caregiver-assisted pain coping skills intervention is feasible and acceptable, and that it may be a promising approach to managing pain in patients with cognitive impairment.
Embryo development in eggs of the spittlebug Mahanarva spectabilis (Distant) (Hemiptera: Cercopidae) passes through four phases (known as S1 to S4) being stopped at S2 during diapause. Studies about the molecular basis of diapause in spittlebugs are nonexistent. Here, we analyzed proteins from non-diapausing (ND), diapausing (D) and post-diapausing (PD) eggs of the spittlebug M. spectabilis. In total, we identified 87 proteins where 12 were in common among the developmental and diapause phases and 19 remained as uncharacterized. Non-diapausing eggs (S2ND and S4ND) showed more proteins involved in information storage and processing than the diapausing ones (S2D). Eggs in post-diapausing (S4PD) had a higher number of proteins associated with metabolism than S2D. The network of protein interactions and metabolic processes allowed the identification of different sets of molecular interactions for each developmental and diapause phases. Two heat shock proteins (Hsp65 and Hsp70) along with two proteins associated with intracellular signaling (MAP4K and a serine/threonine-protein phosphatase) were found only in diapausing and/or post-diapausing eggs and are interesting targets to be explored in future experiments. These results shine a light on one key biological process for spittlebug survival and represent the first search for proteins linked to diapause in this important group of insects.
The diagnosis of visceral leishmaniasis (VL) has improved with the search of novel antigens; however, their performance is limited when samples from VL/human immunodeficiency virus (HIV)-coinfected patients are tested. In this context, studies conducted to identify more suitable antigens to detect both VL and VL/HIC coinfection cases should be performed. In the current study, phage display was performed using serum samples from healthy subjects and VL, HIV-infected and VL/HIV-coinfected patients; aiming to identify novel phage-exposed epitopes to be evaluated with this diagnostic purpose. Nine non-repetitive and valid sequences were identified, synthetized and tested as peptides in enzyme-linked immunosorbent assay experiments. Results showed that three (Pep2, Pep3 and Pep4) peptides showed excellent performance to diagnose VL and VL/HIV coinfection, with 100% sensitivity and specificity values. The other peptides showed sensitivity varying from 50.9 to 80.0%, as well as specificity ranging from 60.0 to 95.6%. Pep2, Pep3 and Pep4 also showed a potential prognostic effect, since specific serological reactivity was significantly decreased after patient treatment. Bioinformatics assays indicated that Leishmania trypanothione reductase protein was predicted to contain these three conformational epitopes. In conclusion, data suggest that Pep2, Pep3 and Pep4 could be tested for the diagnosis of VL and VL/HIV coinfection.
Perinatal death includes losses such as ectopic pregnancies, miscarriages, stillbirths and neonatal deaths. Perinatal loss has well documented negative effects on the health of the bereaved parents. Early pregnancy loss (EPL) is the spontaneous death of a fetus within the first 20 weeks of gestation.
Objectives
To describe a clinical case of disenfranchised grief following EPL and to review the literature.
Methods
We reviewed the clinical file of a patient presenting to the psychiatry outpatient clinic with disenfranchised grief. We conducted a non-systematic review on PubMed and Google Scholar.
Results
A 29-years-old female patient presents to the outpatient clinic with depressive symptoms and thoughts of death. The symptoms had begun 4 months earlier, following the loss of pregnancy at 14 weeks. She felt her grief was not accepted by her family and social network. Progressively, her relationships deteriorated, and she felt more and more isolated. She experienced marked difficulty in caring for her older child. Compared to other types of mourning, the loss of a child is associated with grief experience that is particularly severe and complicated. Despite the high prevalence of EPL, many women suffer in silence due to the common belief these losses are insignificant and may develop complicated grief.
Conclusions
Perinatal loss of an infant has the potential to have a large impact on the mental health of the bereaved parents. Literature on the efficacy of different interventions is still scarce. Further studies are necessary on prevention strategies and interventions for parents already suffering from complicated grief or depressive disorders.
In early 2020, governments started to implement different forms of public health measures, from physical distancing recommendations, to stay-at-home orders, to limit the propagation of COVID-19. Here we report the case of a 41-year-old woman, with a diagnosis of panic disorder. During the end of the lockdown, the patient presented psychopathological worsening, from her fear of Covid-19 infection, stemming from a heart failure disease and concerns regarding the hygiene and safety measures of those around her.
Objectives
Presentation of a clinical vignette.
Methods
Selection and analisis of clinical case and review of the literature using PubMed database.
Results
The COVID-19 pandemic and the measures adopted to prevent the spread of the disease had a huge impact on a personal, social, and economic level for the world population. The rise of fear and anxiety among people due to uncertainty about the disease are coupled with essential yet disruptive measures such as lockdowns and quarantines. The chronically ill population are especially vulnerable during such circumstances and require addressing their physical health and any psychological difficulties they might experience, being at higher risk of suffering physically from the pandemic’s disease as well as psychologically from the implemented countermeasures.
Conclusions
This vignette provides a case where a person’s psychiatric conditions are worsened due to the end of a pandemic lockdown, rather than the lockdown itself. Additional work should aim at comparing the experiences of the different countries affected by the pandemic in order to understand the size of the psychological impact, the potential risk and protective factors.
Psychosocial rehabilitation is a challenge in a society with demands unsuitable for those with severe mental illness (SMI). The Mental Health Department of Matosinhos Local Health Unity (MHD-MLHU) has developed a solidarity project aiming to evaluate and elaborate individualized rehabilitative responses with people with SMI, including people from the community motivated for solidarity initiatives.
Objectives
To describe a psychosocial rehabilitation project focused on community integration of people with SMI, considering needs and resources of the population, and to present the individualized rehabilitation plans carried out for people with SMI.
Methods
In January 2019, we began the home evaluation of people with SMI monitored in the MHD-MLHU. To develop solidary based play-occupational groups, we interviewed people from the community and from the common mental pathology outpatient clinic willing to participate.
Results
We present the description and evaluation of the psychosocial responses developed by the project. These responses include recreational-occupational groups, tailored to interests of each person with SMI, and using the community support group built for the purpose. These responses promote face-to-face activities, and enhance the destigmatization of SMI. The constraints resulting from the COVID-19 pandemic led to the creation of digital responses aimed at people with SMI and the community in general.
Conclusions
This experience has revealed the great potential of rehabilitating the community context of people with SMI, rather than just contemplating pre-existing structured responses. The pandemic created specific challenges but made the initiative even more relevant for SMI people and for promoting the mental health of the general population.
Tourette’s syndrome is a neuropsychiatric disorder marked by motor and phonic tics frequently associated with psychiatric comorbidities, beginning in childhood. While most cases improve or resolve with age, some are refractory.
Objectives
To review new strategies for the management of Tourette’s Syndrome, following an outpatient clinical vignette.
Methods
We performed a review based on the PubMed® database.
Results
A 50-years-old female patient with a long-term outpatient psychiatric follow-up presented with motor tics appearing in adolescence, including winking and facial grimacing, as well as episodes of coprolalia. Over the years, she developed an anxiety disorder and social isolation. In addition to psychological therapy, pharmacological therapy had already been approached with the use alpha-adrenergic agonists and several antipsychotics, such as risperidone and aripiprazole, with the patient showing only partial response to pimozide. In Tourette’s syndrome, the therapy must be adequate to the patient’s individual needs. Emerging treatments for refractory cases, such as anticonvulsants, cannabinoids or antiglutamatergic drugs have been the target of several studies. Botulinum toxin injections are particularly effective in patients with focal motor tics and complex phonic tics. Non-pharmacological treatment options, such as electroconvulsive therapy and deep brain stimulation may prove effective in some cases.
Conclusions
A significant proportion of patients fail to respond to conventional strategies. Thus, new pharmacological and non-pharmacological therapies are on the horizon and may represent an important step in treatment algorithms for refractory cases in the future.
Rates of cannabis use among pregnant women have been increasing. Psychiatrists may be required to provide counselling regarding marijuana use in pregnancy for their patients.
Objectives
To produce an up-to-date review of cannabis effects on pregnancy and the offspring.
Methods
We performed a non-systematic review of the literature apropos a clinical case.
Results
A 31-years-old, 22-weeks pregnant woman presented with severe anxiety, panic attacks and insomnia which she managed solely with cannabis. She had been previously treated with antidepressants and benzodiazepines with symptom remission but had suspended before her pregnancy without medical advice. She believed medication was more harmful to the baby than her cannabis use. There is little perception of risk concerning cannabis use in pregnant woman. Information on cannabis use is less likely to be obtained from healthcare providers than from anecdotal experiences, Internet searching and advice from friends and family. Prenatal use of cannabis has been associated with anaemia in the mother, whereas in the offspring it is associated with reduction in birth weight and greater likelihood of placement in intensive care units. There is insufficient evidence to support an association between marijuana use and any specific congenital abnormality, but also to demonstrate its safety.
Conclusions
It is essential for psychiatrists to have up-to-date knowledge of the effects of cannabis on the pregnancy and the offspring to properly counsel their patients. However, the effects of cannabis on maternal and foetal outcomes remain generally unknown. With rising numbers of female users, there is urgent need for further research.
Dissociative Amnesia remains an enigmatic and controversial entity. It is classically described as responsible for autobiographic amnesia associated with a traumatic event.
Objectives
To report a clinical case and review the literature.
Methods
We collected data from the patient’s clinical file with his informed consent. We conducted a non-systematic review of the literature.
Results
A 46-years-old patient presents to the emergency department for sudden global retrograde amnesia, with multiple domain amnestic syndrome (impairing verbal and visual memory, processing speed, mental flexibility, calculus, executive functions and language). He was initially admitted for a suspected infectious meningoencephalitis, which was not confirmed. Later an autoimmune encephalitis was pursued. Brain MRI showed a nonspecific left temporal and hipocampal hyperintensity and the EEG a mild left temporal dysfunction. The autoimmune encephalitis panel was negative and the formal diagnostic criteria were not met. The neurologic examination at discharge presented only with autobiographical and semantic amnesia. On the mental state examination, he presented with depressive symptoms reactive to the situation. There was no evident traumatic event apart from a promotion received the day before the amnesia started. He was prescribed escitalopram 10 mg/day. The amnesia was maintained at 9 months follow-up.
Conclusions
Our case report illustrates a case of amnesia without evident organic or psychogenic cause, assumed as a dissociative amnesia. Further studies are necessary to clarify the pathophysiology of this condition and develop specific treatments.
Coronavirus disease 2019 (COVID-19) pandemic has had a negative impact for mental health. ULS-Guarda in cooperation with Portugal National Health Service, provided the population of the district of Guarda with a mental health helpline (MHHL).
Objectives
Provide a descriptive data analysis of the MHHL calls received between April 1st and September 20th of 2020.
Methods
The data was obtained through the filling out of questionnaires. It included fields for gender, age, the type of service provided, relation to COVID-19, symptoms displayed and the number calls made per patient. For the statistical analysis, Microsoft Excel TM was utilized.
Results
MHHL received 191 calls. The largest volume was received during April, which saw 116 instances of patients seeking the MHHL. The number of calls then tapered progressively throughout the following months. The services provided were split between psychiatric assistance, psychologic assistance, and the renovation of medical prescriptions, in 44%, 31% and 19% of the cases, respectively. The 101 patients who resorted to the MHHL were unevenly distributed in gender, being 74 female and 27 male individuals. Their ages were mostly between 50 and 69 years old. The most common symptoms were anxiety, depressed humor and insomnia, in 35%, 16% and 11% of the cases, respectively.
Conclusions
The largest influx of calls coincides with the home confinement period, and decreased alongside the relaxation of the confinement measures held. The MHHL had enough adherence to warrant consideration of it being an alternative means of healthcare access, especially in situations where physical access to healthcare is restricted.
The mental health impact of the COVID-19 pandemic is well documented. Portugal entered the emergency state on 19th march due to rising numbers of infected patients. The emergency state introduced regulatory measures that restricted people’s movements, applied a curfew, and closed most non-essential spaces and activities, such as shops and religious celebrations.
Objectives
To evaluate the rates of suicides during the emergency state in Portugal.
Methods
We obtained the number of probable suicides during 19th march and 2nd may 2020, 2019 and 2018 from SICO/eVM (Real Time Mortality Electronic Surveillance). This system is used for health planning in Portugal and provides provisory data which is updated every 10 minutes. ExcelÒ was used for the statistical analysis.
Results
During the Emergency State in Portugal there were 57 probable suicides. Comparing to the same period in 2018 and 2019, there were 62 and 70 probable suicides, respectively. Social isolation, anxiety, fear of contagion, chronic stress, and economic difficulties may lead to the development or exacerbation of depressive, anxiety, substance use, and other psychiatric disorders. Literature on suicides due to COVID-19 mention not only fear of infection, but also social isolation and distancing and economic recession as causes for suicide attempts and completions.
Conclusions
During the emergency state there was not an increase of probable suicides, compared to previous years. The greater vigilance of people’s movements may have deterred many attempts. However, policymakers and health care providers must be alert as the current psychosocial predispose to an increase in suicide rates.
Electroconvulsive therapy (ECT) presents itself as a highly effective therapeutic approach in various psychiatric conditions, especially affective disorders and catatonia. Although obsessive-compulsive disorder (OCD) is not an established indication for ECT, there are several positive results that have been replicated, giving us an account of its potential applicability.
Objectives
To emphasize the importance of defining predictors of response to ECT in OCD.
Methods
The authors’ clinical experience is combined with the review of clinical cases, available in the literature, related to the application of ECT in OCD.
Results
Personal or family history of affective pathology and obsessions of sexual content were identified as potential predictors of response to ECT in patients with obsessive and compulsive symptoms.
Conclusions
Although preliminary and based solely on case reports, the replicability of results should promote special attention to situations in which OCD is marked by particular characteristics that favor the response to ECT. In this way, it would be possible to prevent the dragged consumption of health resources and minimize the expected chronicity associated with this clinical condition.
Chronic pain is common, costly, and associated with significant disability and negative effects on well-being and mental health. The treatment is challenging, requiring a multidisciplinary approach. Acceptance and commitment therapy (ACT) aims to help patients in engaging in a flexible and persistent pattern of values-directed behavior while in contact with continuing pain and discomfort.
Objectives
To provide an updated review on the efficacy of ACT for the management of chronic pain.
Methods
We conducted a systematic review based on the PubMed® and EBSCO databases up to April 2020.
Results
Fifteen trials were included. The results were in favour of ACT in pain acceptance, functioning and pain intensity with small to large effect sizes. Few studies evaluated quality of life, but half of those were favourable to ACT. We also focused our analysis on ACT online interventions, considering the current demands due to the COVID-19 pandemic.
Conclusions
The current systematic review points in favour of ACT for the management of chronic pain conditions, though the studies included suffered from methodological limitations, which may have led to overestimated effects. Methodologically robust trials are required to further understand the clinical efficacy of ACT for chronic pain and which patients most benefit from this intervention.
The development of an extrapyramidal syndrome (EPS) is assumed to be a potential and important consequence of organophosphate poisoning (OP). Even though its causal relationship is firmly established, the information available in the literature regarding the orientation to be given is scarce, and its approach remains shrouded in a significant degree of uncertainty. Catatonia, as a neuropsychiatric condition, may present a marked overlap with the set of extrapyramidal symptoms developed after OP. Does the overlap between the symptoms seen in catatonia and in EPS make differential diagnosis fundamental or does it have no relevance in relation to the approach to be established?
Objectives
To discuss the therapeutic approach to be implemented in the extrapyramidal symptoms resulting from OP and reflect on the overlap between catatonia and EPS.
Methods
Presentation of a clinical case and review of the literature.
Results
A 50-year-old woman with major depressive disorder developed a condition marked by exuberant extrapyramidal symptoms 3 weeks after OP. Significant stiffness, tremor, dysphagia and facial hypomimia were some of the symptoms observed. Therapy was started with amantadine 100mg daily, with complete resolution of the symptoms after 5 days. Follow-up revealed reversal of extrapyramidal symptoms, in the absence of any neuroimaging changes or any other neuropsychiatric manifestations.
Conclusions
The possible overlap between catatonia and EPS is remarkable. The two conditions, regardless of their differentiation, may benefit from an identical approach using dopaminergic drugs. The use of amantadine, even in low doses, may be an option in the rapid reversal of extrapyramidal symptoms resulting from OP.
In the era of widespread resistance, there are 2 time points at which most empiric prescription errors occur among hospitalized adults: (1) upon admission (UA) when treating patients at risk of multidrug-resistant organisms (MDROs) and (2) during hospitalization, when treating patients at risk of extensively drug-resistant organisms (XDROs). These errors adversely influence patient outcomes and the hospital’s ecology.
Design and setting:
Retrospective cohort study, Shamir Medical Center, Israel, 2016.
Patients:
Adult patients (aged >18 years) hospitalized with sepsis.
Methods:
Logistic regressions were used to develop predictive models for (1) MDRO UA and (2) nosocomial XDRO. Their performances on the derivation data sets, and on 7 other validation data sets, were assessed using the area under the receiver operating characteristic curve (ROC AUC).
Results:
In total, 4,114 patients were included: 2,472 patients with sepsis UA and 1,642 with nosocomial sepsis. The MDRO UA score included 10 parameters, and with a cutoff of ≥22 points, it had an ROC AUC of 0.85. The nosocomial XDRO score included 7 parameters, and with a cutoff of ≥36 points, it had an ROC AUC of 0.87. The range of ROC AUCs for the validation data sets was 0.7–0.88 for the MDRO UA score and was 0.66–0.75 for nosocomial XDRO score. We created a free web calculator (https://assafharofe.azurewebsites.net).
Conclusions:
A simple electronic calculator could aid with empiric prescription during an encounter with a septic patient. Future implementation studies are needed to evaluate its utility in improving patient outcomes and in reducing overall resistances.
This study presents an individualized coaching approach tailored to the stages of proximity of promising scientists interested in becoming independently funded researchers in the context of a minority-serving institution. This strategy defined the participant’s stage of proximity by their number of first-author publications in peer-reviewed journals and their track record in submitting research grants. We argue that coaching tailored by stages is an asset to maintain the enthusiasm, persistence, and positive attitude of promising scientists as they try to reach independent investigator status. Furthermore, this valuable educational approach supports the development of management and leadership skills in defined scientific domains.
The main aim of the current study was to present the abilities of widely used crop models to simulate four different field crops (winter wheat, spring barley, silage maize and winter oilseed rape). The 13 models were tested under Central European conditions represented by three locations in the Czech Republic, selected using temperature and precipitation gradients for the target crops in this region. Based on observed crop phenology and yield from 1991 to 2010, performances of individual models and their ensemble were analyzed. Modelling of anthesis and maturity was generally best simulated by the ensemble median (EnsMED) compared to the ensemble mean and individual models. The yield was better simulated by the best models than estimated by an ensemble. Higher accuracy was achieved for spring crops, with the best results for silage maize, while the lowest accuracy was for winter oilseed rape according to the index of agreement (IA). Based on EnsMED, the root mean square errors (RMSEs) for yield was 1365 kg/ha for winter wheat, 1105 kg/ha for spring barley, 1861 kg/ha for silage maize and 969 kg/ha for winter oilseed rape. The AQUACROP and EPIC models performed best in terms of spread around the line of best fit (RMSE, IA). In some cases, the individual models failed. For crop rotation simulations, only models with reasonable accuracy (i.e. without failures) across all included crops within the target environment should be selected. Application crop models ensemble is one way to increase the accuracy of predictions, but lower variability of ensemble outputs was confirmed.
Recent reports on the burden of cardiovascular disease (CVD) in the USA indicate that despite significant declines in CVD mortality in the late 20th century, this decline is now decelerating and may be worsened by inequalities in health care. Social factors contribute to most of the cardiovascular health disparities documented to date. Hispanics/Latinos and African-Americans share a higher prevalence of cardiovascular risk factors and experience higher rates of poverty and social stressors than non-Hispanic Whites. We propose that the use of social and behavioral data beyond basic and sometimes loose identifiers of race/ethnicity, educational attainment, and occupation would inform clinical practice and greatly facilitate the provision of adequate guidance and support to patients regarding continuity of care, adherence to medications and treatment plans, and engagement of participants in future research. This perspective briefly highlights factors deemed to be critical for the advancement of Hispanic/Latino health and delineates pathways toward future applications.
