Authors: Poletto Rodrigo , Gonçalves Victor Miguel , Durigon Marcos Vinicius Cocco , Togashi Adriane Yaeko
Published: July 2023

Os avanços na área de cirurgia bucal melhoraram o prognóstico dos implantes osseointegrados devido ao estudo e desenvolvimento de biomateriais, como a membrana de plasma rico em fibrina (PRF) que pode melhorar o processo de regeneração e a cicatrização. Este trabalho tem como objetivo comparar as técnicas de enxerto conjuntivo subepitelial (TC) e o uso de membranas de PRF, avaliando sua capacidade de cicatrização e manutenção de tecidos ao redor dos implantes osseointegrados. Na amostra com 8 pacientes desdentados totais, cada indivíduo recebeu 02 implantes para fixação de prótese tipo overdenture, sendo que um dos implantes recebeu procedimento cirúrgico regenerativo gengival (grupo TC) e o outro implante recebeu a membrana de plasma rico em fibrina (grupo PRF). Foram avaliados os seguintes parâmetros peri-implantares: profundidade de sondagem, largura de mucosa queratinizada e Implant Stability Quotient (ISQ). Comparando-se as medidas Profundidade de sondagem do grupo TC (2.21mm±0.58) e do grupo PRF (2.21mm±0.52) e largura da mucosa queratinizada do grupo TC (2.17mm±0.67) e do grupo PRF (2.29mm±0.45) entre o tempo inicial (T0) e após 3 a 5 meses (T1), observou-se que não houve diferenças estatísticas (p>0.05). Não houve diferença estatística da Unidade de estabilidade entre o grupo TC (58.93±14.98) e o grupo PRF (62.58±10.51) (p >0.60). A utilização do PRF em cirurgias peri-implantares pode ser considerada como uma opção clínica na manutenção da saúde peri-implantar.

Authors: Santos Antonio Silvestre Figueiredo dos
Published: July 2023

A Medicina Nuclear constitui um método de diagnóstico, que integra substâncias radioativas como o Pertecnetato de Sódio (Tecnécio=TC ⁹⁹m) e o Iodo-131. A Medicina Nuclear, Medicina Legal ou moléculas marcadas com o radioisótopo Pertecnetato de Sódio, associado a fármacos, contribuem para a Ciência Forense. Portanto, como o aspecto energético exerce influências no organismo humano, o presente estudo objetivou descrever as inter-relações entre a Medicina Nuclear, Medicina Legal e Física quântica e suas aplicações às Ciências Forenses. Assim, o estudo de revisão da literatura com abordagem sistemática foi efetuado em junho de 2023, a partir das seguintes bases de dados: Biblioteca Virtual em Saúde (BVS) e Publisher Medline (PubMed) e obteve-se 11 artigos científicos. Logo, verificou-se que o diagnóstico de morte cerebral e estágio vegetativo, baseado em exames de imagem como a Cintilografia Cerebral, contribui para parâmetros jurídicos associados à doação de órgãos para finalidade terapêutica, onde requer a autorização familiar do paciente que evoluiu para óbito. As ondas do cérebro podem associar-se a fundamentos da física quântica. Portanto, o aspecto energético pode influenciar terapias, detecção de enfermidades e consequentemente o organismo humano. Contudo, verificou-se a relevância da Medicina Nuclear no diagnóstico e terapia de enfermidades, que associa-se a Medicina Legal e Ciências Forenses.

Published: July 2023

À medida que a computação em nuvem se torna cada vez mais prevalente em nossas vidas diárias e no ambiente de negócios, é essencial que sejamos conscientes e proativos no gerenciamento do impacto ambiental dessa tecnologia. A computação em nuvem verde é uma abordagem que procura reduzir o consumo de energia e as emissões de CO2 associadas à computação em nuvem, enquanto ainda fornece a funcionalidade e o desempenho necessários. Através do uso de simuladores, como o CloudSim Plus, e da implementação de algoritmos eficientes para a gestão de recursos, este estudo demonstrou que é possível obter melhorias significativas na eficiência energética, reduções nos custos operacionais e uma diminuição no impacto ambiental sem redução da capacidade computacional. Foi observada uma melhoria de pelo menos 49% na eficiência energética, uma redução de pelo menos 7% nos custos diretos e uma diminuição de 50% na emissão de CO2 equivalente. Importante ressaltar que essas melhorias foram obtidas sem comprometer o desempenho dos sistemas, uma vez que os tempos de processamento permaneceram inalterados.

Resultados e Discussão: Uma parcela significativa dos artigos demonstrou que existe correlação entre as fraturas ósseas e a obesidade, embora o papel protetor desta, o qual estava estabelecido, seja questionado atualmente. Conclusão: Foi possível perceber que existem pontos de convergência metabólica entre a fisiopatologia da obesidade e a fisiologia do tecido ósseo, ressaltando a possibilidade teórica de maior fragilidade dos ossos em pacientes obesos.
Lipids in meso- and bathypelagic fishes from the North Atlantic Ocean: dietary inputs suggested from fatty acid trophic markers
Authors: Maar K , Papadimitraki M , Hernández Ruiz L , Broughton R , Jónasdóttir SH
Published: July 2023

Trophic interactions of mesopelagic fishes are key pathways in the vertical transport of carbon through the biological carbon pump. However, diet and feeding behaviours of many members of the mesopelagic community, including lanternfish (Myctophidae) and bristlemouths (Gonostomatidae), remain poorly resolved. We obtained specimens from 1 species of lanternfish, Benthosema glaciale, and several bristlemouths of the genus Cyclothone, from 8 locations in the Northeast Atlantic Ocean, within 19-22° W and 20-55° N, at depths down to 1900 m, and used fatty acid trophic marker (FATM) analysis to assess the main dietary sources and potential feeding habits of those fish. We compared the FA profiles of the fish to those of their zooplankton prey sampled at the same time and locations. The fatty acid composition of the fish separated them into 3 distinct groups. The first group, which included only B. glaciale, was characterized by the phytoplankton trophic markers 16:4 and 18:4(n-3), indicating that the fish had fed on primary consumers, likely zooplankton. The second group included C. microdon and 2 unidentified Cyclothone sp. and was characterized by the monounsaturated FA markers 20:1(n-9) and 22:1(n-11), indicative of lipid-rich calanoid copepods. Finally, the third group, comprising C. pseudopallida and 22 unidentified Cyclothone sp., was characterized by bacterial FA markers (15:0 and 17:0) and saturated FAs (16:0 and 18:0) that, in the deep sea, are likely associated with marine snow. The results show that meso- and bathypelagic fishes sampled at different locations will display differences in FA profiles, reflecting distinct dietary sources. In this way, FATMs may facilitate a better understanding of trophic interactions and energy transfer in deep ocean ecosystems.

Authors: Khan Md. Masudul Islam
Published: July 2023

Due to the widespread interest in cricket in Bangladesh, many individuals are participating in cricket-specific online betting, university students are also participating, and their lives are being impacted in various ways by betting on cricket. Existing literature and newspaper articles have been assessed to identify variables, and a semi-structured questionnaire was developed using the variables. Based on variables, 20 university students from Sylhet were interviewed through in-depth interviews (IDIs). Universities were selected through the purposive sampling technique, and respondents were determined by using snowball sampling. The study demonstrated that university students, who are typically well educated, started betting in student life to earn additional money, but the outcomes seemed largely unpleasant. Betting negatively affects students' academic performance and personal and family relationships. Additionally, they must deal with a variety of mental challenges after starting betting. Even though most university students stop betting after substantial losses, it still influences their lives.

Published: July 2023

Introduction: Bebanga Village, Kalukku District recorded a stunting prevalence of 38.5%. Stunting is caused by various factors, including mothers' lack of knowledge about IYCF. Purpose: To find out the description of knowledge, attitudes, and complementary feeding practices in mothers and the nutritional status of children in the stunting locus area. Methods: The study used a cross-sectional design conducted from January to May 2023 at the Stunting Locus in Bebanga Village, West Sulawesi. A total sample of 148 was calculated using proportional random sampling. Measuring the nutritional status of children uses four indicators: weight/age, height/age, weight/height, and BMI/age Results: The prevalence of stunting children in was 48.0%. As many as 51.5% of mothers had sufficient knowledge about complementary feeding, 51.4% of mothers had a negative attitude about complementary feeding, and as many as 76.4% of mothers practiced complementary feeding not according to standards. The chi-square test showed that the aspects of knowledge (p-value=0.165), attitude (p-value=0.880), and practice (p-value=0.280) of complementary feeding among mothers were not related to the incidence of stunting among children at the stunting locus area. Conclusion: Many stunted children were found among mothers with good knowledge and attitudes toward ICYF but lacked practice.

Published: July 2023

Pancreas transplantation for patients with type 1 diabetes is a therapeutic option when other treatments are not effective and physical complications occur. Psychological burden is prominent in patients, and non-adherence to treatment is often one manifestation of such difficulties. Time projection is an important factor affected by chronic disease. The prospect of transplantation has the potential to repair this disruption. It could re-establish a continuity in the patient’s self and history, by connecting the future to a life that was only about past and present. Taking care of oneself, adhering to treatment, being part of a long-term therapeutic project and going through transplantation are all processes that need a good ability to self-project in time. This is specifically a domain of psychotherapeutic interventions. In this article, the psychological implications of pancreas transplantation for patients and caregivers alike will be discussed, as well as the role of the psychiatrist in the transplantation process.

Published: July 2023

Widely confirmed and applied, data-driven models are an important method for watershed runoff predictions. Since decomposition methods such as time series decomposition cannot automatically handle the decomposition process of date changes and less consideration of influencing factors before decomposition, resulting in insufficient correlation analysis between influencing factors and forecast objects, we propose a method based on hydrological model decomposition to generate time series state variables (broadening the range of influencing factors to be considered). In this study, we constructed hydrological models wherein rainfall and other hydrological elements are decomposed into hydrological and hydrodynamic characteristic state variables to expand the range of the prediction factors. A data-driven model was then built to perform runoff predictions in the Han River Basin. The results showed that compared with the single prediction model, the prediction results based on the coupling model were superior, the performance evaluation grade of the coupling model was high, and the coupling model had a higher stability.
An effective approach for deriving and evaluating approximate optimal design solutions of energy supply systems by time series aggregation
Authors: Yokoyama Ryohei , Shinano Yuji , Wakui Tetsuya
Published: July 2023

It is important to design multi-energy supply systems optimally in consideration of their operations for variations in energy demands. An approach for efficiently solving such an optimal design problem with a large number of periods for variations in energy demands is to derive an approximate optimal design solution by time series aggregation. However, such an approach does not provide any information on the accuracy for the optimal value of the objective function. In this paper, an effective approach for time series aggregation is proposed to derive an approximate optimal design solution and evaluate a proper gap between the upper and lower bounds for the optimal value of the objective function based on a mixed-integer linear model. In accordance with aggregation, energy demands are relaxed to uncertain parameters and the problem for deriving an approximate optimal design solution and evaluating it is transformed to a three-level optimization problem, and it is solved by applying both the robust and hierarchical optimization methods. A case study is conducted on a cogeneration system with a practical configuration, and it turns out that the proposed approach enables one to derive much smaller gaps as compared with those obtained by a conventional approach.
The asymmetric effect of renewable and non-renewable energy on carbon emissions in OECD: new evidence from non-linear panel ARDL model
Authors: Şanlı Devran , Muratoğlu Yusuf , Songur Mehmet , Uğurlu Erginbay
Published: July 2023

The level of economic income, population density and sources of energy supply is critical in assessing environmental quality. Recent empirical studies paid limited attention to the role of renewable (RE) and fossil energy (NRE) supply in carbon pollution regarding the Environmental Kuznets Hypothesis (EKC). Therefore, this study investigates the asymmetric relationships between carbon emissions and energy sources on the one hand and the environmental Kuznets hypothesis on the other hand for OECD countries, comprising countries with significant renewable energy supplies. The study includes the annual data from 1990 to 2021 and performs panel non-linear ARDL regression. The empirical results clearly show that RE and NRE have asymmetric effects on emissions in the long run but not in the short run. Both positive and negative shocks in RE reduce CO2 emissions in OECD economies, while asymmetric shocks in NRE substantially increase them. Increasing RE supply is clearly effective in reducing emissions. However, unlike most previous studies, this study shows that RE does not significantly reduce CO2 emissions in OECD countries. The error correction term (ect.) in the NARDL model is negative and significant. The magnitude of the term indicates that the system will return to long-term equilibrium about 4.2 years after any shock. Furthermore, we show that the EKC Hypothesis is supported in OECD countries. The turning point of the EKC is at $4085.77 per capita. Besides, regression with Driscoll-Kraay standard errors and Augmented Mean Group (AMG) estimator approach were used for robustness checks. The findings from the robustness check are consistent with the NARDL findings. Policies based on the promotion of a low-carbon and sustainable green environment should place greater emphasis on renewable resources even in OECD countries. Moreover, while many studies in the literature address asymmetric effects and EKC as energy consumption or utilisation, the novelty of this study is that it approaches the issue regarding energy supply with asymmetric effects for RE and NRE.
Adaptability in healthcare buildings: a perspective through Joseph Bracops Hospital
Authors: Scialpi Giulia , Declercq Joost
Published: July 2023

The healthcare sector has to face changes happening fast and often in an unpredictable way, such as epidemiological trends, the advancements of medical technology and processes or evolving social and economic needs. This results in a frequent need for infrastructures' retrofitting, with an increasing focus on the environmental impact of buildings, which have one of the highest embodied carbon footprints per square meter in the construction sector. As result, interest in healthcare buildings' adaptability is growing among researchers and practitioners. After an introduction on the research topic, a focus on the definition of adaptability and the existing assessment models is provided to address the following research question: to what extent are adaptability models effective to evaluate and orient the design of healthcare buildings? A quite varied use of the term adaptability has been found in the literature, as well as a new research trend aiming to establish a link with circularity. Moreover, most of the assessment models do not have a focus and have never been tested on the healthcare sector. An approach to circular and adaptable design is presented through the case study of the Joseph Bracops Hospital (Belgium), which has been submitted for evaluation by the Reversible Building Design protocol developed by Dr. Durmisevic. The evaluation highlights some of the current barriers in the design of adaptable healthcare facilities. Insights for future research are provided to encourage data-collection about the service life of healthcare buildings, so to understand if the adaptability of these infrastructures should be mainly monofuntional or transfunctional.
Feeling of hand deformation as a monkey's hand: an experiment on a visual body with discomfort and its algebraic analysis
Authors: Ruijia Yang , Sakura Hirokazu , Gunji Yukio-Pegio
Published: July 2023

While there are many studies in which body ownership can be transferred to a virtual body, there are few experimental studies of how subjects feel about their own bodies being deformed since a real body cannot be deformed. Here, we propose such an experimental setup, in which a twisted hand is diagonally viewed from behind, which is called a “monkey's hand.” Although the subject cannot see the thumb hidden behind his or her arm, he or she feels that the monkey's hand has an ambiguous thumb that functionally never exists but structurally exists. This ambiguity is consistent with experimental results on proprioceptive drift, by which the deformation of the hand is measured. The ambiguity of the presence and absence of the thumb is finally analyzed with a specific algebraic structure called a lattice. This can help us understand disownership as being different from the absence of ownership.
The efficacy of fat-free mass index and appendicular skeletal muscle mass index in cancer malnutrition: a propensity score match analysis
Authors: Ji Wei , Liu XiangLiang , Liu Pengfei , He YuWei , Zhao YiXin , Zheng Kaiwen , Cui JiuWei , Li Wei
Published: July 2023

Background

Reduced muscle mass (RMM) is a phenotypic criterion for malnutrition; the appendicular skeletal muscle mass index (ASMI) and fat-free mass index (FFMI) are both applicable indicators in the global leadership initiative on malnutrition (GLIM) guideline. However, their sensitivity and prognostic effect remain unclear.

Methods

Clinical data of 2,477 patients with malignant tumors were collected. Multi-frequency bioelectrical impedance analysis was used to obtain ASMI and FFMI. RMM was confirmed by ASMI (< 7.0 kg/m2 for men and < 5.7 kg/m2 for women) or FFMI (< 17 kg/m2 for men and < 15 kg/m2 for women). Propensity score match analysis and logistic regression analysis were used to evaluate the efficacy of FFMI and ASMI in diagnosing severe malnutrition and multivariate Cox regression analysis to determine the efficacy of RMM in predicting survival.

Results

In total, 546 (22.0%) and 659 (26.6%) participants were diagnosed with RMM by ASMI (RMM.ASMI group) and FFMI (RMM.FFMI group); 375 cases overlapped. Body mass index (BMI), midarm circumference, triceps skinfold thickness, and maximum calf circumference were all significantly larger in the RMM.FFMI group for both sexes (P < 0.05). A 1:1 matched dataset constructed by propensity score match contained 810 cases. RMM.FFMI was an influential factor of severe malnutrition with HR = 3.033 (95% CI 2.068–4.449, P < 0.001), and RMM.ASMI was a predictive factor of overall survival (HR = 1.318, 95% CI 1.060–1.639, P = 0.013 in the RMM.ASMI subgroup, HR = 1.315, 95% CI 1.077–1.607, P = 0.007 in the RMM.FFMI subgroup).

Conclusion

In general, RMM indicates negative clinical outcomes; when defined by FFMI, it predicts nutritional status, and when defined by ASMI, it is related to poor survival in cancer patients.

Published: July 2023

Introduction

Caffeine is one of the most used drugs in the neonatal intensive care units (NICUs). It is widely regarded as beneficial in preventing many morbidities by reducing apnea of prematurity and improving respiratory functions.

Methods

Premature infants with gestational ages >25 and <32 weeks who were hospitalized in the NICU between 2008 and 2013 and survived up to discharge were retrospectively analyzed. Infants treated with prophylactic caffeine were compared with historical controls born in 2008 and did not receive caffeine treatment. Maternal and neonatal characteristics and common neonatal morbidities were recorded.

Results

A total of 475 patients were analyzed. The patients receiving caffeine were classified as Group 1 (n = 355), and the patients not receiving caffeine were classified as Group 2 (n = 120). Despite the higher incidence of respiratory distress syndrome requiring surfactant therapy and a longer duration of respiratory support in Group 2, the rates of bronchopulmonary dysplasia (BPD) and most other common morbidities were quite comparable. The frequency of apnea was statistically lower in the group that received caffeine prophylaxis (p < 0.01).

Conclusion

In this retrospective cohort analysis, we found that caffeine prophylaxis significantly decreased apnea attacks however does not prevent respiratory morbidity such as BPD.

Giant fibroepithelial polyp (FP) of the scrotum in infants is a rare disease. We reported the first case of FP in China. The child was only 9 months and 12 days old and was admitted to the hospital due to rapid growth and rupture of the scrotal mass. The patient underwent scrotal exploration under general anesthesia, and the mass was cystic-solid with clear boundaries. The tumor did not invade the sarcolemma of the scrotum and testicular tissue. The intraoperative pathological frozen section tended to be benign, and the scrotum's tumor and subcutaneous pedicle tissue were removed entirely after 0.5 cm from the boundary of the mass. The operation was successful. The mass was confirmed as FP by postoperative pathology. 6 months after the operation, the incision healed well without recurrence. This case report has a detailed diagnosis and treatment process and adequate examination results. It can provide a reference for diagnosing and treating FP in infants and reduce the risk of misdiagnosis and mistreatment.

Objective

The aim of this study was to evaluate the clinical efficacy of single-incision laparoscopy appendectomy (SILA) and traditional three-hole laparoscopy appendectomy (THLA) for the treatment of acute appendicitis in children.

Methods

The clinical data of children (<14 years old) who underwent laparoscopic appendectomy at Yijishan Hospital of Wannan Medical College, Hubei Provincial Maternal Health Hospital and Qingdao Women and Children's Medical Center from January 2019 to June 2022 were retrospectively analyzed. According to the operation method, the patients were assigned to the SILA group or the THLA group. The clinical data, including the efficacy, and the surgical details, including the complications, of the two surgical methods were compared. The personal information of the children and the time of disease onset were recorded.

Results

In this study, the data of 588 patients, including 385 patients in the THLA group and 203 patients in the SILA group were collected. The baseline characteristics between the two groups of patients before surgery were comparable. There was no significant difference in the average operation time between the THLA group and the SILA group (56.31 ± 1.83 min vs. 57.48 ± 1.15 min, P > 0.05). There was also no significant difference in the average length of hospital stay between the THLA group and the SILA group (6.91 ± 0.24 days vs. 7.16 ± 0.36 days, P > 0.05). However, the FLACC scores of the SILA group (3.71 ± 0.78) were significantly lower than those of the THLA group (3.99 ± 0.56) on the second postoperative day, and the difference was significant (P < 0.05). The score of the questionnaire evaluating cosmetic appearance of the postoperative abdomen was significantly higher in the SILA group (15.81 ± 0.36) than in the THLA group (13.10 ± 0.24) (P < 0.05). There was no significant difference in the incidence of postoperative complications between the two groups (P > 0.05).

Conclusion

SILA is more advantageous in terms of postoperative FLACC scores and cosmetic appearance in children than THLA. There was no significant difference in the incidence of complications or other aspects between the two surgical methods.

Purpose

Our purpose was to verify the existence of birthplace and relative age effect (RAE), as well as the association between birthplace effect and RAE among Brazilian athletes competing in the Olympic Games.

Methods

Data included information about Brazilian Summer Olympic athletes from 1920 to 2021. To investigate RAE, athletes’ birthdate was distributed into birth quartiles (Q1: Jan–Mar; Q2: Apr–Jun; Q3: Jul–Sep; Q4: Oct–Dec), while birthplace effect was assessed considering the state and the region (Southeast; Northeast; South; North; and Midwest) of birth. The Chi-square test (χ2) was used to verify differences between the birthplace effect and RAE.

Results

The sample consisted of 388 Brazilian athletes of both sexes, distributed in 38 sports modalities from 23 Brazilian states (Southeast = 66.5%; South = 14.4%; Northeast = 12.1%; North = 1.5%; Midwest = 5.4%). For both sexes, most of the athletes were from the São Paulo state (37.4%), followed by Rio de Janeiro (18.3%), both from the Southeast region. For birthdate distribution according to birthplace, it was observed that the North region presented the highest frequency of athletes born in Q1 (50%), followed by the Northeast and Southeast regions. No significant differences were found for the birthplace effect (χ2 = 5.69, value of p = 0.128) and RAE between sexes (χ2 = 0.530, value of p = 0.912), nor was shown an association between the birthplace effect and RAE.

Conclusion

Most Brazilian Olympic athletes are from the Southeast region, but no RAE was established regarding their birthplace. Results from the present study can guide sports public policies in Brazilian regions, especially in the Midwest, North, and Northeast regions, which are underrepresented in Brazilian high-performance sports.
Factor structure of school readiness skills: conceptual vs. statistical distinctions

Published: July 2023

Introduction

School readiness skills are a broad set of abilities that children develop in early childhood that support achievement once they enter formal schooling. Three components of school readiness skills are of focus in the current study: executive function (EF), language/literacy, and mathematics. The current study examines to what extent 13 direct assessments of these skills statistically align with theoretical models for distinct construct- and timepoint-specific latent factors.

Methods

The sample included 684 children (52.34% male; 42% Black/African American; Mage = 4.80 years in the fall of prekindergarten) assessed in the fall and spring of the prekindergarten year.

Results

Factor analyses revealed the most statistical support for a model with a latent random intercept across timepoints and constructs, along with timepoint-specific latent factors in the fall and spring of prekindergarten (independent of the random intercept). The timepoint-specific latent factors primarily consisted of early literacy and mathematics assessments.

Discussion

These findings challenge commonly held practices of creating construct-specific latent factors in early childhood research and, to a lesser extent, timepoint-specific latent factors without consideration of the substantial shared variance across different constructs and timepoints. Implications for the factor structure and developmental theory of school readiness skills are considered, as well as practical considerations for future research.

Published: July 2023

Background

The impacts of the COVID-19 pandemic on the mental health of survivors are little known, especially regarding the occurrence of psychological disorders such as anxiety and depression. In this study, we evaluated the impacts on the mental health of Brazilian survivors who were not infected or asymptomatic with COVID-19.

Methods

A cross-sectional study was conducted collecting information through an electronic form from January to May 2021. The sample consisted of 1,334 people and were divided into two groups: case, with individuals who reported a positive diagnosis of the disease, with or without symptoms, and control, who reported not being diagnosed with COVID-19 and did not present any symptoms during the collection period. Validated instruments were used to investigate symptoms of depression (Patient Health Questionnaire), anxiety (Generalized Anxiety Disorder-7), post-traumatic stress disorder (Post Traumatic Stress Disorder Checklist) and insomnia (Insomnia Severity Index). The data were presented as standard deviation or median and interquartile ranges. The chi-square test was applied for statistical significance between categorical variables, considering a p < 0.05.

Results

Regarding post-traumatic stress levels, the case and control groups showed no differences (p = 0.82). The results of the research indicated that was no statistical correlation between the group that was affected by the virus infection and the group that was not affected in terms of depression (p = 0.9) and anxiety (p = 0.7). At the same time, the levels of insomnia (p = 0.02) demonstrated a statistical correlation between the groups. The prevalence of the analyzed mental health disorders was similar among both groups.

Conclusion

In conclusion, the population of survivors of COVID-19 infection tends to show little difference in terms of developing post-traumatic stress disorder, anxiety, and depression when compared to uninfected individuals. On the other hand, disorders such as insomnia are more prevalent and show a significant difference between groups, appearing more in infected individuals.

Introduction

Medical clearance for patients with primary psychiatric complaints presenting to the emergency department has been debated for decades. Emergency physicians have argued that clearance labs are unnecessary, yet psychiatrists may still order or require them. A retrospective review was conducted to evaluate the continued need for labs of psychiatric patients and help identify high risk groups that may need additional intervention prior to medical clearance.

Methods

Charts of 163 patients from Ochsner LSU Shreveport Psychiatric Crisis Unit (PCU) were reviewed with data collected of history, physical examination, review of systems, vitals and routine lab work including complete blood count (CBC), comprehensive metabolic panel (CMP), urine drug screen (UDS), serum ethanol level (EtOH), urinalysis (UA), creatine kinase (CK), urine pregnancy test (UPT), and rapid COVID-19.

Results

Review identified 82 patients (50.3%) that received interventions prior to medical clearance. Most common intervention was intravenous (IV) fluids (n = 59; 45%) followed by admission to other service (n = 15; 8.4%), imaging (n = 10; 7.6%), antihypertensive medication (n = 3; 3.1%), cardiac workup (n = 3; 2.3%), antibiotics (n = 3; 2.3%), lorazepam for undocumented reasons (n = 2; 1.5%). Additional interventions completed once included immunizations, antiseizure medication, pain medication, and additional lab work. Causes for IV fluids were reviewed with elevated creatine kinase (CK) (n = 31; 50.8%) being most common. Additional causes included undocumented (n = 12; 19.7%), tachycardia (n = 6; 9.8%), elevated EtOH level (n = 3; 4.9%), dehydration (n = 2; 3.3%), acute kidney injury (AKI) (n = 2; 3.3%), leukocytosis following a seizure (n = 1; 1.6%), elevated CK and leukocytosis (n = 1; 1.6%), and AKI and elevated CK (n = 1; 1.6%). Most common cause for medical admission was elevated CK being cited in 8 out of 15 admissions (53.3%). Additional causes for admission included AKI (n = 2; 14.3%), seizures and leukocytosis (n = 1; 6.7%), rule out of acute coronary syndrome (ACS) (n = 1; 6.7%), alcohol withdrawal (n = 1; 6.7%), encephalopathy with drop in hemoglobin and white blood cell count (n = 1; 6.7%), and encephalopathy with elevated CK (n = 1; 6.7%).

Discussion

Our results support the recommended guidelines set by AAEP for laboratory testing in addition to history, vital signs and physical examination prior to medical clearance. Certain laboratory testing such as CK and CMP were identified to have higher utility for medical intervention while other lab work such as UA and UDS had less of an impact. Further, we suggest that specifically a CK and CMP be obtained on patients presenting with any of the following: agitation, abnormal vital signs, intoxication, or a history of or current stimulant use as these were factors correlated with lab abnormalities that led to interventions.
