Actualities in immunological markers and electrochemical sensors for determination of dopamine and its metabolites in psychotic disorders (Review)

Psychotic disorders represent a serious health concern. At this moment, anamnestic data, international criteria for diagnosis/classification from the Diagnostic and Statistical Manual of Mental Disorders-5 and the International Classification of Diseases-10 and diagnostic scales are used to establish a diagnosis. The most commonly used biomarkers in psychotic illnesses are those regarding the neuroimmune system, metabolic abnormalities, neurotrophins and neurotransmitter systems and proteomics. A current issue faced by clinicians is the lack of biomarkers to help develop a more accurate diagnosis, with the possibility of initiating the most effective treatment. The detection of biological markers for psychosis has the potential to contribute to improvements in its diagnosis, prognosis and treatment effectiveness. The mixture of multiple biomarkers may improve the ability to differentiate and classify these patients. In this sense, the aim of this study was to analyze the literature concerning the potential biomarkers that could be used in medical practice and to review the newest developments in electrochemical sensors used for dopamine detection, one of the most important exploited biomarkers.
Role of Chest Computed Tomography versus Real Time Reverse Transcription Polymerase Chain Reaction for Diagnosis of COVID-19: A Systematic Review and Meta-Analysis

Background The current global pandemic of COVID-19 is considered a public health emergency. The diagnosis of COVID-19 depends on detection of the viral nucleic acid by real time reverse transcription polymerase chain reaction (RT-PCR). However, false-negative RT-PCR tests are reported and could hinder the control of the pandemic. Chest computed tomography could achieve a more reliable diagnosis and represent a complementary diagnostic tool. Aim To perform a meta-analysis and systematic review to find out the role of chest computed tomography versus RT-PCR for precise diagnosis of COVID-19 infection. Methods We searched three electronic databases (PubMed, ScienceDirect, and Scopus) from April 1 to April 20, 2020, to find out articles including the accuracy of chest computed tomography scan versus RT-PCR for diagnosis of SARS-CoV-2 infection. Observational studies, case series, and case reports were included. Results A total of 238 articles were retrieved from the search strategy. Following screening, 39 articles were chosen for full text assessment and finally 35 articles were included for qualitative and quantitative analysis. Chest computed tomography showed a wide range of sensitivity varied from 12%–100%. Conclusion Chest computed tomography is playing a key role for diagnosis and detection of COVID-19 infection. Computed tomography image findings may precede the initially positive RT-PCR assay.
To Nap or Not to Nap? A Systematic Review Evaluating Napping Behavior in Athletes and the Impact on Various Measures of Athletic Performance

Purpose The objective of this systematic review was to 1) determine how studies evaluated napping behavior in athletes (frequency, duration, timing and measurement); 2) explore how napping impacted physical performance, cognitive performance, perceptual measures (eg, fatigue, muscle soreness, sleepiness and alertness), psychological state and night-time sleep in athletes. Methods Five bibliographic databases were searched from database inception to 11 August 2020. Observational and experimental studies comprising able-bodied athletes (mean age ≥12 years), published in English, in peer-reviewed journal papers were included. The Downs and Black Quality Assessment Checklist was used for quality appraisal. Results Thirty-seven studies were identified of moderate quality. Most studies did not include consistent information regarding nap frequency, duration, and timing. Napping may be beneficial for a range of outcomes that benefit athletes (eg, physical and cognitive performance, perceptual measures, psychological state and night-time sleep). In addition, napping presents athletes with the opportunity to supplement their night-time sleep without compromising sleep quality. Conclusion Athletes may consider napping between 20 to 90 min in duration and between 13:00 and 16:00 hours. Finally, athletes should allow 30 min to reduce sleep inertia prior to training or competition to obtain better performance outcomes. Future studies should include comprehensive recordings of nap duration and quality, and consider using sleep over a 24 hour period (daytime naps and night-time sleep period), specifically using objective methods of sleep assessment (eg, polysomnography/actigraphy).
Ziziphus jujuba (Rhamnaceae) Alleviates Working Memory Impairment and Restores Neurochemical Alterations in the Prefrontal Cortex of D-Galactose-Treated Rats

Alzheimer's disease is a progressive cognitive dysfunction. However, pharmacological treatments are symptomatic and have many side effects, opening the opportunity to alternative medicine. This study investigated the antiamnesic effect of the aqueous extract of Ziziphus jujuba on D-galactose-induced working memory impairment in rats. Impairment of working memory was induced by subcutaneous (s.c.) injection of D-galactose (350 mg/kg/day) to rats for 21 days. These animals were then subjected to object recognition and Y-maze tests. Rats with confirmed memory impairment were treated per os (p.o.) with tacrine (10 mg/kg), aspirin (20 mg/kg, p.o.), extract (41.5, 83, and 166 mg/kg, p.o.), and distilled water (10 mL/kg, p.o.) daily for 14 days. At the end of the treatments, alteration in working memory was assessed using the above paradigms. Afterward, these animals were euthanized, and cholinergic, proinflammatory, and neuronal damage markers were analyzed in the prefrontal cortex. Rats administered D-galactose and treated with distilled water had impaired working memory (evidenced by decreased time spent on the novel object and discrimination index) and decreased spontaneous alternation in the Y-maze. D-galactose also decreased the levels of acetylcholinesterase and acetylcholine and increased the level of glial fibrillary acidic protein, ionized calcium-binding adapter molecule 1, tumor necrosis factor-alpha (TNF-α), interleukin 1 beta (IL-1β), interleukin 6 (IL-6), and interferon-gamma (IFN-γ). Treatment with the extract (166 mg/kg) reversed the time spent on the novel object and the discrimination index. It equally increased the percentage of spontaneous alternation. Neurochemical analysis revealed that the extract markedly alleviated acetylcholinesterase activity and neuroinflammation. These observations were corroborated by the reduction in neuronal loss. Taken together, these results suggest that Ziziphus jujuba aqueous extract possesses an antiamnesic effect. This effect seems to involve cholinergic and anti-inflammatory modulations. This, therefore, claims using this plant in the treatment of dementia in Cameroon subject to further studies and trials.
Total Flavonoids of Crocus sativus Petals Release tert-Butyl Hydroperoxide-Induced Oxidative Stress in BRL-3A Cells

Antioxidant and hepatoprotective activities in vitro of saffron petals were examined in this study for better utilizing saffron (Crocus sativus L.) biowaste. Using the DPPH and ABTS radical scavenging method, we compared the antioxidant activity and the content of total flavonoid extracts from petals (TFESP), stamens (TFESS), and both saffron petals and stamens (TFEMS). The results showed that the antioxidant capacity and the flavonoid content of TFESP were higher than those of TFESS and TFEMS. Then, the hepatoprotective activity of TFESP was determined, and the silymarin was used as a positive control. The main components of TFESP were analysed by ultrahigh performance liquid chromatography (UPLC) photodiode array (PDA)/mass spectrometry (MS) and nuclear magnetic resonance (NMR). The result showed that (1) TFESP could release oxidative liver injury induced by tert-butyl hydroperoxide (t-BHP). (2) TFESP could reduce the accumulation of reactive oxygen species (ROS); enhance the activity of superoxide dismutase (SOD), catalase (CAT), and glutathione (GSH); and then improve the total antioxidant capacity (T-AOC) in BRL-3A cells. (3) TFESP could enhance the expression of B-cell lymphoma-2 (BCL-2) and decrease the expression of caspase-3 and caspase-9; increase the expression of Kelch-like ECH-associated protein-1 (Keap-1), nuclear factor, erythroid 2-related factor 2 (Nrf2), superoxide dismutase, and heme oxygenase 1 (HO-1); and downregulate inducible nitric oxide synthase (INOS), interleukin-6 (IL-6), and nuclear factor kappa B-9 (NF-κB-9). (4) The main hepatoprotective component of TFESP was identified as kaempferol-3-o-sophoroside. The mechanism may be that kaempferol-3-o-sophoroside can protect t-BHP-induced cell injury by regulating the expression of antioxidant, antiapoptotic, and anti-inflammatory genes. Thus, saffron petals are a potential hepatoprotective resource worthy of development.
Effect of Standing After Preheating on the Softening Rate of Root Vegetables

Japanese radish and potato samples were preheated at 60 _ 70°C for 10 min and maintained at 20°C for 0 _ 7 h to control the changes in hardness. The slopes of the first order plots for softening and the Arrhenius plots of the softening rate constant were linear. The softening rate constants of Japanese radish and potato were reduced to 18 _ 49% and 23 _ 50%, respectively, compared to the fresh vegetables. The optimum cooking times of Japanese radish and potato samples with respect to hardness, calculated based on the softening rate constants, were 1.9 _ 6.7 and 1.5 _ 4.0 times longer, respectively, compared to fresh samples. To prevent browning and the elution of soluble components, samples were vacuum-packed, then pretreated, heated and subjected to sensory evaluation. All samples were evaluated for optimum hardness.
Retrospective Study on Acute Kidney Injury among Cholera Patients in an Outbreak in Whitefield, Bengaluru

Introduction Cholera is gastroenteritis caused by Vibrio cholerae. It presents with vomiting, severe secretory diarrhoea, and dehydration. It can cause severe complications with severe electrolyte imbalances and oligoanuric acute kidney injury due to acute tubular necrosis secondary to dehydration or infection itself. However, cholera presenting with significant proteinuria and acute kidney injury has not been reported. Hence, this study was conducted. Aims and Objectives. This aim of this study was to assess clinical features, treatment, and prognosis of AKI in cholera patients; to correlate proteinuria with AKI in cholera patients; and to compare cholera patients with normal kidney function and those with AKI. Material and Methods. It was a retrospective observational study involving patients with cholera. Information regarding cholera patients with acute kidney injury, proteinuria, and prognosis were collected. Results Most of the patients had significant vomiting, moderate-to-severe diarrhoea, dehydration, and hypovolaemic shock. Cholera caused severe complications such as severe electrolyte imbalances including hyponatraemia and hypokalaemia, acute kidney injury, and proteinuria secondary to dehydration or infection. A surprising finding noted was the lack of significant association between the onset of acute kidney injury and usual risk factors such as hypovolaemic shock and dehydration. It was found that proteinuria had influenced the onset of acute kidney injury, but it did not influence recovery. As there was complete recovery in kidney function, none of the cases required kidney biopsy. There was no mortality noted. Conclusions This study points towards the rare occurrence of proteinuria and acute kidney injury in Vibrio cholerae infection with spontaneous remission of kidney disease with appropriate therapy.
COVID‐19 Causing Burnout Among Medical Students

Emotional exhaustion, excessive depersonalization, and reduced personal achievement define the burnout syndrome. The academic workload on students can cause exhaustion, similar to that of a worker. The Maslach Burnout Inventory‐ Student Survey (MBI‐SS) was designed to reflect student burnout by evaluation of emotional exhaustion, cynicism, and academic efficacy. It has been reported that at least half of the students will suffer burnout at some point in their medical studies. Burnout evaluation has been focused on physicians or those working in hospitals attending coronavirus patients. The psychological burden and pressures on students due to the closure of facilities and schools around the world has not been thoroughly evaluated. The objective was to evaluate the prevalence of burnout in medical students during the COVID‐19 pandemic.
Knowledge and attitude towards HIV/AIDS in India: A systematic review and meta-analysis of 47 studies from 2010-2020

Background: Several studies assessed the level of knowledge and general public behavior on human immunodeficiency virus/acquired immuno-deficiency syndrome (HIV/AIDS) in India. However, comprehensive scrutiny of literature is essential for any decision-making process. Our objective was to perform a systematic review and meta-analysis to examine the level of knowledge and attitude towards HIV/AIDS in India. Methods: A systematic search using Medical Subject Headings (MeSH) and free terms was conducted in PubMed/Medline, Scopus, Embase, and Google Scholar databases to investigate the level of knowledge and attitude of HIV/AIDS in India population. Cross-sectional studies published in English from January 2010 to November 2020 were included. The identified articles were screened in multiple levels of title, abstract and full-text and final studies that met the inclusion criteria were retrieved and included in the study. The methodological quality was assessed using the Joanna Briggs Institute’s checklist for cross-sectional studies. Estimates with corresponding 95% confidence intervals (CIs) for each domain were pooled to examine the level of knowledge and attitude towards HIV/AIDS in India. Results: A total of 47 studies (n= 307 501) were identified, and 43 studies were included in the meta-analysis. The overall level of knowledge about HIV/AIDS was 75% (95% CI: 69-80%; I2 = 99.8%), and a higher level of knowledge was observed among female sex workers (FSWs) 89% (95% CI: 77-100%, I2 = 99.5%) than students (77%, 95% CI: 67-87%, I2 = 99.6%) and the general population (70%, 95% CI: 62-79%, I2 = 99.2%), respectively. However, HIV/AIDS attitude was suboptimal (60%, 95% CI: 51-69%, I2 = 99.2%). Students (58%, 95% CI: 38-77%, I2 = 99.7%), people living with HIV/AIDS (57%, 95% CI: 44-71%, I2 = 92.7%), the general population (71%, 95% CI: 62-80%, I2 = 94.5%), and healthcare workers (HCWs) (74%, 95% CI: 63-84%, I2 = 0.0%) had a positive attitude towards HIV/AIDS. The methodological quality of included studies was "moderate" according to Joanna Briggs Institute’s checklist. Funnel plots are asymmetry and the Egger’s regression test and Begg’s rank test identified risk of publication bias. Conclusion: The level of knowledge was 75%, and 40% had a negative attitude. This information would help formulate appropriate policies by various departments, ministries and educational institutions to incorporate in their training, capacity building and advocacy programs. Improving the knowledge and changing the attitudes among the Indian population remains crucial for the success of India’s HIV/AIDS response.
Studying effects of neuromuscular electrostimulation therapy in patients with dysphagia: which pitfalls may occur? A translational phase I study

Background: Previous results of clinical studies suggest that neuromuscular electrostimulation (NMES) therapy, especially in combination with traditional dysphagia therapy, may be helpful in patients with neurogenic swallowing disorders. In these studies, repetitive application of a rectangular current impulse was used to increase muscle strength of the anterior neck. However, according to sports physiological findings, an increase of muscle strength can be better achieved by using different NMES stimulation protocols, e.g. KOTS. The aim of the translational investigator-initiated, non-commercial pilot study presented here was to provide data and insights for the planning of subsequent phase II and III studies on the effectiveness of such stimulation protocols in dysphagia therapy. Methods: 30 post-stroke patients with oropharyngeal dysphagia were included in this prospective pilot study and randomly allocated to either neuromuscular electrostimulation (NMES) or sham stimulation in combination with traditional dysphagia therapy (TDT), a pre- and post-therapeutic fiberoptic-endoscopic evaluation of swallowing (FEES) with the Dysphagia Outcome and Severity Scale (DOSS) (primary outcome measure), Secretion Scale by Murray, Penetration and Aspiration Scale (PAS) and throat clearance (TC) abilities. Recruitment rate, interrater comparison and number of relevant adverse events were recorded as metadata. Results: Despite a recruiting time of over 24 months, only twelve patients could be included. Moreover, clinical data indicated a significant variance of clinical pictures. Significant differences in verum versus sham therapy were not observed. DOSS values in both study groups showed general improvements at the end of the trial. Interrater reliability was low. No adverse events were reported. Discussion: When planning further dysphagia therapy studies, it must be taken into account that it can be problematic to recruit sufficiently large study collectives within an appropriate study period. This is especially important since a possible additional benefit of NMES to TDT is probably rather small or may only occur in certain deficit constellations. The low interrater reliability observed here must be improved by appropriate training measures. Fortunately, no relevant undesirable side effects occurred. This could have a positive effect on the acceptance of volunteers to participate in the study.
Cancer-epigenetic function of the histone methyltransferase KMT2D and therapeutic opportunities for the treatment of KMT2D-deficient tumors

Epigenetic mechanisms are central to understanding the molecular basis underlying tumorigenesis. Aberrations in epigenetic modifiers alter epigenomic landscapes and play a critical role in tumorigenesis. Notably, the histone lysine methyltransferase KMT2D (a COMPASS/ Set1 family member; also known as MLL4, ALR, and MLL2) is among the most frequently mutated genes in many different types of cancer. Recent studies have demonstrated how KMT2D loss induces abnormal epigenomic reprograming and rewires molecular pathways during tumorigenesis. These findings also have clinical and therapeutic implications for cancer treatment. In this review, we summarize recent advances in understanding the role of KMT2D in regulating tumorigenesis and discuss therapeutic opportunities for the treatment of KMT2D-deficient tumors.
Association between Maternal Dietary Diversity and Low Birth Weight in Central India: A Case-Control Study

Low birth weight (LBW) is one of the major public health challenges in India. LBW etiology is multifactorial and linked to multiple determinants, including maternal undernutrition and sociodemographic characteristics. The objective of the present endeavor was to assess how maternal dietary diversity and other sociodemographic factors among marginalized populations are associated with the incidence of LBW. The study was a part of the community-based intervention that aimed to improve maternal and child health in the Morena district of Madhya Pradesh, a state in central India. In this case-control study, cases were defined as mothers with an LBW child (<2500 grams) and controls as mothers without an LBW child. A quantitative survey was done with women of reproductive age, having at least one child aged 0–24 months. We calculated the dietary diversity based on the number of food groups consumed during pregnancy by women on a daily basis. Stepwise logistic regression models were built to test for associations between sociodemographic and dietary diversity variables and LBW incidence. There were 157 mothers with and 214 without an LBW child. Women's diets mainly consisted of grains, such as wheat, rice, maize, and roots and tubers. Eggs and meat were consumed by less than 1% of the women. There were 20% lesser chances of an LBW child with increasing maternal dietary diversity scores (odds ratio: 0.79; 95% CI: 0.65, 0.96). The poor maternal diet quality during pregnancy may result in adverse birth outcomes with long-term consequences in a child.
Knowledge, Attitudes, Practices, and Determinants Towards Wastewater Management in Northwest Ethiopia: A Community-Based Cross-Sectional Study

Background Globally, waste management has been a major public health problem. Public knowledge, attitudes, practices (KAP) and participation are key elements of any waste management program. In Ethiopia, however, the level of KAP and associated factors regarding wastewater management (WWM) at the household level are not well studied and understood. This study was, therefore, conducted to assess the knowledge, attitude, practice and associated factors of wastewater management (WWM) among the residents in Gondar town, Ethiopia. Methods A community-based cross-sectional study was conducted during March and April, 2016. A total of 422 participants were selected using the systematic random sampling technique. A structured questionnaire was employed to collect data which were entered and analyzed using the Statistical Package for Social Science (SPSS) version 20. A multivariable binary logistic regression analysis was used to ascertain the significance of associations at <0.05 p-value and the adjusted odds ratio (AOR) with a 95% confidence interval (CI). Results Among 422 study participants included, 63.5%, 43.4%, and 48.6% of them had good knowledge, attitudes, and self-reported practices regarding WWM, respectively. Knowledge of participants was significantly associated with house rent (AOR 1.12, 95% CI (1.22, 3.69), civil servant (AOR 5.47, 95% CI (1.87, 8.02), and positive attitudes (AOR 2.69, 95% CI (1.68, 4.30), while space availability (AOR 1.84, 95% CI (1.23, 2.75), and good knowledge (AOR 2.46, 95% CI (1.61, 3.77) were associated factors of attitudes. Moreover, good knowledge (AOR 1.32, 95% CI (1.87, 2.02), and positive attitudes (AOR 1.03, 95% CI (1.01, 2.34) were significantly associated factors of self-reported practices. Conclusion Limited knowledge, attitudes and practices were seen among study population. A great emphasis on improvement of knowledge, attitudes and practices towards WWM is necessary. Moreover, it would be better to qualitatively explore variables which explain the qualitative attributes of the community, like community Attitudes and knowledge.
