Factors Contributing to False Negative Results when Performing Diagnostics of COVID-19 by Reverse Transcription-Polymerase Chain Reaction in Real Time

Reverse transcription-real-time polymerase chain reaction (RT-PCR) is currently the leading laboratory diagnostic tool for COVID-19. With the help of RT-PCR-RT, diagnostics is carried out at the early stages of the development of the disease. The studied clinical samples, as a rule, are swabs from the pharynx and nasopharynx. The aim of the work is to identify and analyze the factors that contribute to false negative results when diagnosing COVID-19 by RT-PCR-RT. It is shown in the article, that the analytical sensitivity of the real-time RT-PCR method is not the main factor in assessing the possibility of obtaining false negative results. The paper considers the effect of drinking hot drinks (tea, coffee), alcohol and smoking (immediately before sampling) on the results of the analysis of swabs from the pharynx and nasopharynx by RT-PCR RT. It was found that the intake of hot drinks before sampling (the probability of obtaining a false negative result is at least 80%) influences most of all on the possibility of obtaining a false negative result in RT-PCR-RT in swabs from the pharynx. The use of small doses of alcohol (0.25–0.33 g of ethanol per 1 kg of body weight) has a lesser effect. Smoking immediately prior to sample collection does not lead to a false negative result in real-time RT-PCR. None of the considered influences affects the possibility of obtaining false negative results in the analysis of swabs from the nasopharynx. Recommendations were made on the need for simultaneous examination of both throat swabs and nasopharyngeal swabs in the ongoing diagnosis of COVID-19.

Alcohol and health. Is regular drinking of small doses of alcohol really good for your health?

Alcohol has been drunk for centuries and in the past also used as a medicine. Alcohol consumption in Poland and in the entire world has gradually increased, which is also nowadays accelerated by the ongoing COVID-19 pandemic. In 2020, the amount of alcohol consumed in Poland was 11.7 l per capita, which was a the highest level since 1961. It is estimated that global alcohol consumption will increase by 17% by the year 2030. There is also increasing alcohol consumption by children and adolescents, as well as pregnant women. Alcohol consumption as a health damaging factor is not always recognized in the general population. Additionally, numerous scientific societies in their guidelines/recommendations indicate that moderate doses of alcohol are beneficial or at least neutral for health. The question remains whether so-called “moderate doses of alcohol” really are not harmful to health. We analyze this issue in this article.

The alcohol flushing response is associated with the risk of depression

The alcohol flushing response is experienced by 36–45% of East Asians after they consume a small amount of alcohol. Because individuals with this response are unable to metabolize the toxic acetaldehyde derived from alcohol effectively, the response offers a potential indicator of the health risks associated with alcohol intake. Depression is a major health problem linked to alcohol consumption; it might also be associated with the alcohol flushing response. Therefore, we examined the association between the alcohol flushing response and the risk of depression in the general population of South Korea. Our analysis included 139,380 participants and used data from the 2019 Korean Community Health Survey. Only current drinkers were considered in the analysis. The relationship between the alcohol flushing response and depression was evaluated by logistic regression analysis using SAS 9.4. Of the participants, more than one-third were current flushers; compared to never flushers, current flushers had a significantly greater risk of depression (adjusted odds ratio [AOR] 1.23, 95% confidence interval [CI] 1.12–1.34, P < 0.001). Former flushers did not exhibit a risk of depression. The risk of depression was significantly greater among alcohol flushers who drank < 15 g alcohol/day (< 5 g alcohol/day: AOR 1.20, 95% CI 1.07–1.35, P = 0.002; 5–14.9 g alcohol/day: AOR 1.39, 95% CI 1.13–1.70, P = 0.002). In conclusion, a large number of South Koreans experience the alcohol flushing response; compared with never flushers, current flushers are more likely to develop depression with a small dose of alcohol (< 15 g alcohol/day).

An Analysis of the Effect of selected Factors on microsurgical Performance.

Microsurgery is a specific surgical expertise that involves operating on very small structures, and requires the assistance of a magnifying device: a microscope or loupes. Several factors have been identified that could affect the quality of microsurgical performance in training or surgical procedures. The objective of this study was to assess the impact of the selected factors - caffeine, alcohol and physical exercise - on a microsurgical task prior its performance. Ten students from the 5th and 6th years of medical studies who had completed the advanced microsurgical course performed a "6-stitches test" on a latex glove spanned over a cup prior to and after consumption of caffeine, alcohol and performing physical exercises. The times taken to complete the task at baseline and post-exposure were recorded. The results of the study show a statistically significant positive effect of caffeine and a statistically significant negative effect of physical exercise on microsurgical performance when performed shortly before the task. Small dose of alcohol taken before the task showed had little effect on performance.

Metabolic Changes in Newborns and Women Who Consumed Small Doses of Alcohol in the Prenatal Period

Introduction: Ethyl alcohol and its metabolites even in low concentrations negatively affectsan embryo and a fetus.Interest to the role of the lipid peroxidation-antioxidant defense (LPO-AOD) system has significantly increased in recent years, because this system imbalanceleads to the development of oxidative stress (OS), which is accompanied by body's resistance decreaseto the adverse environmental and internal factors negative influence, which is one of the most important triggers of so-called free radical pathology.&#x0D; Aim: The aim of research was to determine the concentration and activity of the metabolic system components “lipid peroxidation-antioxidant defense” (LPO-AOD) and the glutathione system components in pregnant women who consumed no more than 2 doses of low-strength alcoholic beverages (beer, champagne, wine) during the first half of pregnancy and their newborns.&#x0D; Methods: The design of the study was prospective and controlled randomized. The study involved 170 pregnant women who were observed in the regional perinatal center of Irkutsk. Two women refused to participate in the study. The main group consisted of 93 women who drank low alcohol beverages (beer, champagne and wine) in the first half of pregnancy (for a period of 7-20 weeks of pregnancy). The control group composed of 75 women who did not drink alcohol throughout their pregnancy. In both groups of women for a period of 30-32 weeks of pregnancy, the parameters of the LPO-AOD and glutathione systems had been determined. Similarly, cord blood had been sampled in 66 control group newborns and 53 newborns whose mothers drank alcohol in the first half of pregnancy (main group). Statistical processing of the research results was performed. Statistical processing of the results obtained had been carried out using the software package STATICTICA 10 Stat Soft Inc, USA (license holder - Scientific Centre for Family Health and Human Reproduction Problems) using the T - student and Mann-Whitney test methods.&#x0D; Results: The study revealed the influence of the use of low alcohol beverages (beer, champagne and wine) in an amount of no more than 2 doses on the state of the LPO-AOD and glutathione systems in the blood serum and red blood cells of pregnant women and their newborns. It was found that even a single intake of low alcohol beverages is accompanied byoxidative stress development in women and their newborns. The state of the glutathione system in pregnant women is characterized by a decrease in the content of reduced glutathione (GSH) and glutathione reductase (GR) activity with an increase in the oxidized glutathione (GSSG) and glutathione-S-transferase (GST) levels. In newborns, a decrease in GSH is associated with a decrease in the of GR, GST, and glutathione peroxidase (GPO) activity.&#x0D; Conclusion: Analyzing the data, in distant perspective the negative role of even small doses of low alcohol (beer, champagne and wine) on pregnant women and their newborns metabolism was established.

Effects of Acute Alcohol Consumption on Cycling Anaerobic Exercise Performance: A Randomized Crossover Study

PURPOSE: Some athletes consume alcohol prior to training and sports events, possibly because they believe that alcohol may aid in reducing pain and anxiety, increasing confidence, and promoting aggressiveness. While previous studies have shown that alcohol consumption acutely impairs endurance exercise performance, its effects on anaerobic exercise performance have not been well established. Therefore, this study investigated the effect of a small dose of alcohol on anaerobic exercise performance.METHODS: In a randomized crossover design, nine healthy and recreationally active males (n=6) and females (n=3) participated in the study. Subjects consumed 0.7 g of alcohol per kg of lean body mass or a calorie/volume-matched sucrose beverage. Reaction time tests were performed before and 25 minutes after beverage consumption. Following the second reaction time test, subjects performed the 20-second Wingate anaerobic test (WAnT).RESULTS: Compared to the sucrose drink, alcohol showed no significant effects on peak power (p=.903), average power (p=.970), percentage power drop during WAnT (p=.593), or total energy produced during WAnT (p=.923). Moreover, alcohol did not affect the time course of power output during a 20s WAnT (p=.999 for all time points). In addition, reaction time was not significantly different when comparing alcoholic with sucrose drinks at different timepoint (Before; p=.999, After; p=.364).CONCLUSIONS: Although some athletes consume alcohol prior to engaging in sports events, assuming that it may improve anaerobic exercise performance, the results of the present study show that acute consumption of alcohol does not have effects on anaerobic exercise performance when compared to the control beverage.

Rat Hepatoma BRL Cells Proliferation by Acrylamide and Alcohol Combination

Acrylamide, exists in carbohydrate-rich food heated at high temperatures, is a probable carcinogen to humans. Excessive alcohol intake can also lead to a variety of pathological changes in the body. Acrylamide in the foods and alcohol in the drinks are unavoidable. And studies have demonstrated that combination of the two substances which are taken into the body via diet may cause adverse effects in the cells, even induce impairments on testicular spermatogenesis in male offsprings. Both acrylamide and alcohol are mainly metabolized in the liver, where cytochrome P450 2E1 (CYP2E1) acts as the common metabolic enzyme of the two xenobiotics. This study aimed to explore the effects of acrylamide and alcohol combination on rat hepatoma BRL cells proliferation and the probable mechanisms. MTT, western blotting, EdU fluorescence staining, flow cytometry and PCR were used. Results showed that combination of acrylamide and alcohol at low doses promoted BRL cells proliferation through CYP2E1/Akt/ NF-κB/cyclinB1/cyclinD1 activation and ROS production. The combined effects of acrylamide and alcohol largely depended on ROS level. Furthermore, acrylamide and alcohol could synergistically induce miR-21, which was related to the progress of liver regeneration. These data showed that combination of acrylamide and alcohol at low doses promoted BRL cells proliferation through inducing ROS production, which indicated that intake of fried starch food with small dose of alcohol might have positive effects on liver regeneration.

Effect of Different Foods Together With a Small Dose of Alcohol on Alcohol Levels in Healthy Subjects

Effect of Different Foods Together With a Small Dose of Alcohol on Alcohol Levels in Healthy Subjects

Is a Meal without Wine Good for Health?

Hippocrates, the father of medicine, had said: “Wine is a thing wonderfully appropriate to man if, in health as in disease, it is administered with appropriate and just measure according to the individual constitution.” Wine has always accompanied humanity, for religion or for health. Christians and Jews need wine for the liturgy. For Plato, wine was an indispensable element in society and the most important in the symposium. In this second part of the banquet, mixed with water, the wine gave the word. If the French paradox made a lot of ink flow; it was the wine that was originally responsible for it. Many researchers have tried to study alcohol and polyphenols in wine, in order to solve the mystery. Beyond its cardiovascular effects, there are also effects on longevity, metabolism, cancer prevention, and neuroprotection, and the list goes on. The purpose of this work is to make an analysis of the current knowledge on the subject. Indeed, if the paradigm of antioxidants is seductive, it is perhaps by their prooxidant effect that the polyphenols act, by an epigenetic process mediated by nrf2. Wine is a preserve of antioxidants for the winter and it is by this property that the wine acts, in an alcoholic solution. A wine without alcohol is pure heresy. Wine is the elixir that by design, over millennials, has acted as a pharmacopeia that enabled man to heal and prosper on the planet. From Alvise Cornaro to Serge Renaud, nutrition was the key to health and longevity, whether the Cretan or Okinawa diet, it is the small dose of alcohol (wine or sake) that allows the bioavailability of polyphenols. Moderate drinking gives a protection for diseases and a longevity potential. In conclusion, let us drink fewer, but drink better, to live older.

Does the Neuroimmune Modulator Ibudilast Alter Food Craving? Results in a Sample With Alcohol Use Disorder.

Ibudilast (IBUD) is a neuroimmune modulator that inhibits phosphodiesterase-4 and -10 and macrophage migration inhibitory factor. A randomized, placebo-control, crossover human laboratory trial advanced IBUD development for alcohol use disorder and found that IBUD reduced tonic levels of alcohol craving. Given the importance of considering medication effects on other appetitive behavior, the present study tested the effect of IBUD (50 mg bid) on food craving. The present study was a secondary data analysis of the trial of IBUD in non-treatment seekers with alcohol use disorder (N = 19). High-fat/high-sugar food craving was measured daily. Moreover, because substantial literatures show that small alcohol doses and psychological stress increase eating of high-fat/high-sugar food, craving for high-fat/high-sugar food was measured after alcohol infusion and stress reactivity. Results indicated that IBUD did not alter tonic high-fat/high-sugar food craving. Alcohol infusion did not generally increase high-fat/high-sugar food craving but psychological stress did. Likewise, IBUD did not affect high-fat/high-sugar food craving after alcohol infusion but IBUD did increase high-fat/high-sugar food craving after psychological stress. Follow-up analyses revealed that, among individuals with lower depressive symptomatology, IBUD compared to placebo heightened the effect of psychological stress on high-fat/high-sugar food craving. These results advance the development of IBUD for addiction indications by demonstrating that IBUD compared to placebo does not suppress other appetitive responses, namely craving for high-fat/high-sugar food among individuals with alcohol use disorder.

When an enemy becomes a friend. On the benefits of alcohol consumption

While use of high doses of alcohol is a proven risk factor for various organs and systems, use of small and moderate doses bears evidence of the opposite data. Thus, regularly drinking a small amount of alcoholic drinks could reduce a person’s chances of developing coronary heart disease, stroke, type 2 diabetes, non-alcoholic fatty liver disease, osteoporosis and some other diseases, and also reduce overall mortality. Small doses of alcohol suppress the inflammation and peroxidation, normalize hemocoagulation, improve the lipid profile, favourably affect blood vessel tone and the insulin-signaling pathways. Positive effects of wine are the most studied, which is usually explained by the fact that it contains polyphenols, while positive effects of beer are studied to a lesser extent; however, it should be borne in mind that the studies were aimed at different types of alcoholic beverages. Thus, it can be considered inappropriate to completely prohibit the use of alcohol to persons without dependence and specific organ damage.

Opportunities of high-technology phenotyping by the NMR spectroscopy method by example of the metabolic response of the rat liver to the effect of alcohol and Reishi

The metabolic profiling of the rat liver was carried out in order to estimate the efficiency of proton nuclear magnetic resonance (1H NMR) spectroscopy as a method of metabolomic phenotyping and a method of detecting early metabolic changes during toxic effects. The tissue samples were taken from three groups of rats: group C, control animals; group A, animals that repeatedly received 15% alcohol solution (its intake induced no pathological liver changes, but stimulated the proliferation of the hepatocytes); and group A + R, alcohol in combination with the plant hepatoprotective Reishi preparation (Ganoderma lucidum). As follows from the results obtained, the changes in the metabolite concentration in liver (observed in group A) reflected the typical metabolic reaction to the alcohol intake and were expressed in a decrease in the content of glycine, leucine, isoleucine, valine, choline, and lactate, as well as in an increase in the TMAO level. The concentration of glycine, valine, and TMAO was restored in the rats of group A + R during the Reishi intake. In addition, an increase in the concentrations of NAD, ATP, UTP, succinate, pyranose, and acetate was registered in group A + R relative to the control. Individual variations in the content of valine, isoleucine, leucine, lactate, choline, and pyranose is correlated to the number of binuclear hepatocytes (as an indicator of proliferative activity). Thus, the study of liver tissues by 1H NMR spectroscopy method allows us to detect early deviations in the level of metabolites during chronic consumption of small alcohol doses and can be a promising approach both for diagnostic detection of alcoholic liver damage and for estimation of the efficiency of the applied drug therapy.

Personal determinants of acceptance of drinking and driving among Polish drivers

&lt;b&gt;Background&lt;/b&gt;&lt;br /&gt; &lt;br /&gt; The aim of the study was to explore a number of personal predictors that increase one’s approval of driving under the influence (DUI). In keeping with the previous studies, we assumed this approval will more often be expressed by unmarried young men with a lower level of education, who are additionally characterized by a higher need for stimulation, risk acceptance, sensation seeking, and a preference for hedonic values.&lt;br /&gt; &lt;br /&gt; &lt;b&gt;Participants and procedure&lt;/b&gt;&lt;br /&gt; &lt;br /&gt; After examining more than 1000 drivers, we selected a group of 254 individuals (97 men, 157 women) who formed our study group. In our survey, these drivers admitted to driving while intoxicated in the past, but at the same time declared that small doses of alcohol did not limit their driving skills. We used a set of research tools in order to verify the assumptions. The following tools measured temperamental and personality variables: Formal Characteristics of Behavior-Temperament Inventory, Risk Acceptance Scale, Stimulating-Instrumental Risk Inventory, Scheler Value Scale, Rotter’s Locus of Control Scale, and Zuckerman’s Sensation Seeking Scale.&lt;br /&gt; &lt;br /&gt; &lt;b&gt;Results&lt;/b&gt;&lt;br /&gt; Driving under the influence of alcohol is most often approved of by unmarried men who have a higher level of education and are characterized by low levels of sensory sensitivity, low levels of emotional reactivity, an internal locus of control, a high need for risks, high sensation-seeking tendencies, and who prefer vital and aesthetic values.&lt;br /&gt; &lt;br /&gt; &lt;b&gt;Conclusions&lt;/b&gt;&lt;br /&gt; It is well justified to examine personal predictors of various dangerous road behaviors, such as driving under the influence of intoxicating substances. These studies could aid both creating effective social prevention programs and conducting psychological screening tests.

LPO-Antioxidant Defense System in Newborns and Women Drinking Small Amounts of Alcohol During Pregnancy.

We studied the effects of consumption of low-alcohol drinks (no more than 2 doses) during pregnancy on the state of LPO-antioxidant defense system and glutathione level in the blood serum and erythrocytes of pregnant women and newborns. It was found that even single alcohol intake was followed by the development of oxidative stress in women and newborns. In pregnant women, the decrease in reduced glutathione content and glutathione reductase activity associated with increased level of oxidized glutathione and glutathione transferase activity were typical changes. In newborns, the decrease in reduced glutathione concentration was accompanied by a decrease in glutathione reductase, glutathione transferase, and glutathione peroxidase activities. It should be emphasized that even small alcohol doses produce delayed negative effects on metabolism of the mother and newborns.

Alcohol as a risk factor for cancer: existing evidence in a global perspective.

The purpose of the present review is to give an overview of the association between alcohol intake and the risk of developing cancer. Two large-scale expert reports; the World Cancer Research Fund (WCRF)/American Institute of Cancer Research (AICR) report from 2007, including its continuous update project, and the International Agency for Research of Cancer (IARC) monograph from 2012 have extensively reviewed this association in the last decade. We summarize and compare their findings, as well as relate these to the public health impact, with a particular focus on region-specific drinking patterns and disease tendencies. Our findings show that alcohol intake is strongly linked to the risk of developing cancers of the oral cavity, pharynx, larynx, oesophagus, colorectum (in men), and female breast. The two expert reports diverge on the evidence for an association with liver cancer and colorectal cancer in women, which the IARC grades as convincing, but the WCRF/AICR as probable. Despite these discrepancies, there does, however, not seem to be any doubt, that the Population Attributable Fraction of alcohol in relation to cancer is large. As alcohol intake varies largely worldwide, so does, however, also the Population Attributable Fractions, ranging from 10% in Europe to almost 0% in countries where alcohol use is banned. Given the World Health Organization’s prediction, that alcohol intake is increasing, especially in low- and middle-income countries, and steadily high in high-income countries, the need for preventive efforts to curb the number of alcohol-related cancers seems growing, as well as the need for taking a region- and gender-specific approach in both future campaigns as well as future research. The review acknowledges the potential beneficial effects of small doses of alcohol in relation to ischaemic heart disease, but a discussion of this lies without the scope of the present study.

Effect of Alcohol Administration on Mg2+ Homeostasis in H9C2 Cells.

Alcoholic cardiomyopathy represents one of the main clinical complications in chronic alcoholics. This pathology contrasts the seemingly beneficial effect of small doses of alcohol on the cardiovascular system. Studies carried out in liver cells exposed acutely or chronically to varying doses of EtOH indicate that intrahepatic alcohol metabolism results in a major loss of cellular Mg2+. To investigate whether EtOH administration also induced Mg2+ extrusion in cardiac cells, H9C2 cells were exposed to varying doses of EtOH for short- or ling-term periods of time. The results indicate that H9C2 cells exposed to EtOH doses higher than 0.1% (v/v, or 15 mM) extruded Mg2+ into the extracellular medium on a time- and dose-dependent manner. Consistent with the involvement of cyP4502E1 in metabolizing EtOH, administration of chloro-methiazole (CMZ) as an inhibitor of the cytochrome prevented EtOH-induced Mg2+ loss to a large extent. EtOH-induced Mg2+ extrusion was also prevented by the administration of di-thio-treitol (DTT) and n-acetyl-cysteine (NAC), two agents that prevent the negative effects of ROS formation and free radicals generation associated with EtOH metabolism by cyP4502E1.Taken together, our data indicate that Mg2+ extrusion also occur in cardiac cells exposed to EtOH as a result of alcohol metabolism by cyP4502E1 and associated free radical formation. Interestingly, Mg2+ extrusion only occurs at doses of EtOH higher than 0.1% administered for an extended period of time. The significance of Mg2+ extrusion for the onset of alcoholic cardiomyopathy remains to be elucidated.

Reversed Scototaxis during Withdrawal after Daily-Moderate, but Not Weekly-Binge, Administration of Ethanol in Zebrafish

Alcohol abuse can lead to severe psychological and physiological damage. Little is known, however, about the relative impact of a small, daily dose of alcohol (daily-moderate schedule) versus a large, once per week dose (weekly-binge schedule). In this study, we examined the effect of each of these schedules on behavioural measures of anxiety in zebrafish (Danio rerio). Adult wild-type zebrafish were administered either 0.2% ethanol on a daily-moderate schedule or 1.4% ethanol on a weekly-binge schedule for a period of 21 days, and then tested for scototaxis (preference for darkness) during withdrawal. Compared to a control group with no alcohol exposure, the daily-moderate group spent significantly more time on the light side of the arena (indicative of decreased anxiety) on day two of withdrawal, but not day 9 of withdrawal. The weekly-binge group was not significantly different from the control group on either day of withdrawal and showed no preference for either the light or dark zones. Our results indicate that even a small dose of alcohol on a daily basis can cause significant, though reversible, changes in behaviour.

“Pause and plan” includes the liver: Self-regulatory effort slows alcohol metabolism for those low in self-control

During self-regulatory effort, a series of potentially energy-saving changes occur in the heart and immune system. The present study tested the possibility that one function of the liver, alcohol metabolism, also slows in the presence of self-regulatory effort. Young men (N=19) received a small dose of alcohol and performed either self-regulatory tasks or identical tasks without a self-regulatory component, counterbalanced across two sessions. There was no main effect of condition on alcohol metabolism; however, trait self-control moderated the effect of condition such that those with higher trait self-control metabolized alcohol at similar rates across conditions, whereas those with lower trait self-control experienced a slowing of alcohol metabolism in the high self-regulation condition compared with the low self-regulation condition. This finding adds changes in liver metabolism to the “pause and plan” profile of self-regulation and suggests that trait self-control reduces the effort associated with self-regulatory tasks.

Mixing an Energy Drink with an Alcoholic Beverage Increases Motivation for More Alcohol in College Students

There has been a dramatic rise in the consumption of alcohol mixed with energy drinks (AmEDs) in social drinkers. It has been suggested that AmED beverages might lead individuals to drink greater quantities of alcohol. This experiment was designed to investigate whether the consumption of AmEDs would alter alcohol priming (i.e., increasing ratings of wanting another drink) compared with alcohol alone. Participants (n=80) of equal gender attended 1 session where they were randomly assigned to receive 1 of 4 doses (0.91ml/kg vodka, 1.82ml/kg energy drink, 0.91ml/kg vodka mixed with 1.82ml/kg energy drink [AmED], or a placebo beverage). Alcohol-induced priming of the motivation to drink was assessed by self-reported ratings on the Desire for Drug questionnaire. The priming dose of alcohol increased the subjective ratings of "desire" for more alcohol, consistent with previous research that small doses of alcohol can increase the motivation to drink. Furthermore, higher desire ratings over time were observed with AmEDs compared with alcohol alone. Finally, ratings of liking the drink were similar for the alcohol and AmED conditions. An energy drink may elicit increased alcohol priming. This study provides laboratory evidence that AmED beverages may lead to greater motivation to drink versus the same amount of alcohol consumed alone.
