The Impact of COVID-19 Lockdowns in Germany on Mood, Attention Control, Immune Fitness, and Quality of Life of Young Adults with Self-Reported Impaired Wound Healing.

BACKGROUND: Previous studies in Dutch young adults revealed that individuals with self-reported impaired wound healing reported poorer mood, increased inattention and impulsivity, poorer quality of life, and poorer immune fitness compared to healthy controls. Another study revealed that the negative impact of lockdowns during the 2019 coronavirus disease (COVID-19) pandemic was significantly more profound among the impaired wound healing group than the control group. The purpose of the current study was to replicate and extend these findings among young adults living in Germany. METHODS: A retrospective, cross-sectional survey was conducted among N = 317 young adults living in Germany, 18-35 years old. They were allocated to the IWH group (N = 66) or the control group (N-251). Participants completed the Attention Control Scale, and mood, quality of life, and immune fitness were assessed with single-item ratings. All assessments were made for (1) the period before the COVID-19 pandemic, (2) the first lockdown period, March-May 2020, (3) the first no-lockdown period, summer 2020, (4) the second lockdown, November 2020 to May 2021, and (5) the second no-lockdown period, summer 2021. RESULTS: The impaired wound healing group reported significantly poorer mood, quality of life, and immune fitness. The effects were evident before the pandemic. The impaired wound healing group scored significantly poorer on attention focusing, but no significant differences between the groups were found for attention shifting. During the pandemic, negative lockdown effects (i.e., further aggravation of mood and immune fitness and lower quality of life) were evident in both groups but significantly more profound in the impaired wound healing group. No differences between the groups were found for the no-lockdown periods. CONCLUSION: Individuals with self-reported impaired wound healing have significantly poorer mood, attention focusing, and immune fitness and report a poorer quality of life than healthy controls. The impact of COVID-19 lockdowns was significantly more profound in the impaired wound-healing group.

Alcohol Consumption, Hangovers, and Smoking among Buenos Aires University Students during the COVID-19 Pandemic.

In Argentina, the 2019 coronavirus disease (COVID-19) pandemic led to serious changes to social interaction, health, economy, and education. Argentina experienced two extensive lockdown periods. University education remained virtual for almost two academic years. The purpose of the present work was to analyze the impact of the COVID-19 lockdowns in Argentina on alcohol consumption, hangover severity and smoking among university students in Buenos Aires. A retrospective online survey was conducted in 2021 among students of the University of Buenos Aires. Participants aged 18-35 years old were asked about the average number of alcoholic drinks and number of drinking days per week, binge drinking occasions, drunkenness, next day hangover severity, number of hangovers per month, and smoking behavior. The results showed that the first and second COVID-19 lockdowns were associated with significant reductions in both weekly alcohol consumption, and hangover severity and subjective intoxication on their heaviest drinking occasions. Males consumed significantly more alcohol than females, and older students (25-35 years old) consumed more alcohol than younger students (18-24 years old). In addition, younger students reduced the number of cigarettes smoked per day during the two lockdown periods while older students exhibited significantly more smoking days per week. In conclusion, the present work in Argentinian students revealed a significant reduction in weekly alcohol consumption, and subjective intoxication and hangover severity on their heaviest drinking occasions during the pandemic lockdown periods.

The COLIBAS Study—COVID-19 Lockdown Effects on Mood, Academic Functioning, Alcohol Consumption, and Perceived Immune Fitness: Data from Buenos Aires University Students

A recent study was conducted in the Netherlands to evaluate the impact of the 2019 coronavirus (COVID-19) pandemic and its associated lockdown periods on academic functioning, mood, and health correlates such as alcohol consumption. The study revealed that lockdowns were associated with a significantly poorer mood and a reduced perceived immune fitness. Overall, a reduction was seen in alcohol consumption during the lockdown periods. Academic functioning in terms of performance was unaffected;however, a significant reduction in interactions with other students and teachers was reported. There was, however, great variability between students as follows: both an increase and a reduction in alcohol consumption were reported, as well as improvements and poorer academic functioning. The aim of the current online study was to replicate these findings in Argentina. To this extent, a modified version of the survey was conducted among students at the University of Buenos Aires, which was adapted to the local lockdown measures. The survey assessed possible changes in self-reported academic functioning, mood, and health correlates, such as alcohol consumption, perceived immune functioning, and sleep quality compared to before the COVID-19 pandemic. Retrospective assessments were made for four periods, including (1) the period before COVID-19, (2) the first lockdown period (March–December 2020), (3) summer 2021 (January-March 2021, no lockdown), and (4) the second lockdown (from April 2021 to July 2021). This article describes the content of the survey and the corresponding dataset. The survey was completed by 508 participants.

COVID-19 Lockdown Effects on Mood, Alcohol Consumption, Academic Functioning, and Perceived Immune Fitness: Data from Young Adults in Germany

Recently, a study was conducted in the Netherlands to evaluate the impact of the coronavirus disease (COVID-19) pandemic and its associated lockdown periods on academic functioning, mood, and health correlates, such as alcohol consumption. The Dutch study revealed that lockdowns were associated with significantly poorer mood and reductions in perceived immune fitness. Overall, a reduction in alcohol consumption during lockdown periods was shown. Academic functioning in terms of self-reported performance was unaffected. However, a significant reduction in interactions with other students and teachers was reported. However, there was considerable variability among students;both increases and reductions in alcohol consumption were reported, as well as both improvements and poorer academic functioning during periods of lockdown. The aim of the current online study was to replicate these findings in Germany. To achieve this, a slightly modified version of the survey was administered among young adults (aged 18 to 35 years old) in Germany. The survey assessed possible changes in self-reported academic functioning, mood, and health correlates, such as smoking and alcohol consumption, perceived immune functioning, and sleep quality during periods of lockdown as compared to periods with no lockdowns. Retrospective assessments were made for five periods, including (1) 'BP' (the period before the COVID-19 pandemic), (2) 'L1' (the first lockdown period, March–May 2020), (3) 'NL1' (the first no-lockdown period, summer 2020), (4) 'L2' (the second lockdown, November 2020 to May 2021), and (5) 'NL2' (the second no-lockdown period, summer 2021). This article describes the content of the survey and the corresponding dataset. The survey was completed by 371 participants.

Impaired wound healing is associated with poorer mood and reduced perceived immune fitness during the COVID-19 pandemic: A retrospective survey.

Background and Aims: The coronavirus disease-2019 (COVID-19) pandemic disrupted medical care of patients with chronic wounds, and in combination with other negative effects of lockdown measures, this may have a negative effect on mood and quality of life. Until now, the consequences of the COVID-19 pandemic and associated lockdowns for individuals with impaired wound healing have not been investigated. Methods: An online survey was conducted to evaluate perceived immune fitness, mood, and health, both before and during the COVID-19 pandemic. Results: Of the 331 Dutch pharmacy students that completed the survey, N = 42 participants reported slow healing wounds and/or wound infection and were allocated to the impaired wound healing group; the other N = 289 participants served as control group. The survey assessed mood, perceived immune fitness, and health correlates for (a) the year 2019 (the period before the lockdown), (b) the first lockdown period (March 15-May 11, 2020), (c) summer 2020 (no lockdown), and (d) the second lockdown (November 2020-April 2021). The analysis revealed that negative mood effects, reductions in quality of life, and perceived immune fitness during the two lockdowns were significantly more pronounced among individuals that reported impaired wound healing compared to the control group. The effects on mood, perceived immune fitness, and health correlates were most pronounced for the second lockdown period. Conclusion: The COVID-19 pandemic is associated with significantly poorer mood, quality of life, and reduced perceived immune fitness. These effects are significantly more pronounced among individuals with self-reported impaired wound healing.

Pandemic Preparedness: The Potential Advantage of Medicines That Prevent Acute Side Effects of Vaccination, SARS-CoV-2 as an Example

Vaccination against SARS-CoV-2 is an important and essential strategy to combat the 2019 coronavirus disease (COVID-19) pandemic. Vaccination has shown to be effective in reducing the spread of SARS-CoV-2, reducing the chances of becoming infected and developing severe COVID-19, and reducing hospitalization and mortality rates. However, the vaccinations against SARS-CoV-2 are accompanied by undesirable side effects which may be in part responsible for a reduction in the willingness to become vaccinated. At this moment (June 2022), 24.3% of the US adult population (18+ years old) is not fully vaccinated against SARS-CoV-2, and 49.5% did not receive their follow-up booster vaccination. The most important motives for refusing vaccination are the unknown long-term side effects and the known acute side effects of vaccination. Here, we discuss the importance of recognizing the impact of this reactogenicity on individuals' willingness to vaccinate and how the development of effective and safe medicines that prevent or mitigate the unwanted side effects of the vaccination may help to increase the willingness to vaccinate.

Pandemic Preparedness: Maintaining Adequate Immune Fitness by Attaining a Normal, Healthy Body Weight.

In addition to developing effective medicines and vaccines, pandemic preparedness also comprises general health-related, behavioral, and psychological aspects related to being more resistant in the case of future pandemics. In the context of the 2019 coronavirus (COVID-19) pandemic, recent research revealed that reduced perceived immune fitness was the best predictor of reporting more frequent and more severe COVID-19 symptoms. Up until now (June 2022), during the COVID-19 pandemic, the majority of patients who have been hospitalized were characterized as being overweight. It is therefore essential to further evaluate the relationship between body mass index (BMI) and immune fitness. This was performed by analyzing pooled data from previously published studies, conducted among N = 8586 Dutch adults. It was hypothesized that attaining a normal, healthy body weight is associated with optimal perceived immune fitness. The analysis revealed that a deviation from normal weight (i.e., having a BMI outside the range of 18.5 to 24.9 kg/m2) was associated with significantly reduced perceived immune fitness, as assessed with the immune status questionnaire and a single item perceived immune fitness scale. The effects were significant for both underweight and overweight groups and most pronounced for the obese groups. The results suggest that attaining a normal, healthy body weight might significantly contribute to maintaining adequate perceived immune fitness. Therefore, attaining a normal body weight might be an essential component of pandemic preparedness and should be supported by creating awareness and promoting the importance of regular exercise and the consumption of healthy food.

Pandemic Preparedness: The Importance of Adequate Immune Fitness.

Pandemic preparedness is an important issue in relation to future pandemics. The two studies described here aimed to identify factors predicting the presence and severity of coronavirus disease 2019 (COVID-19) symptoms. The CLOFIT study comprised an online survey among the Dutch population (n = 1415). Perceived immune fitness before the pandemic (2019) and during the first lockdown period (15 March-11 May 2020) and the number and severity of COVID-19 symptoms were assessed. The COTEST study, conducted between December 2020 and June 2021, replicated the CLOFIT study in n = 925 participants who were tested for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in Dutch commercial test locations. The CLOFIT study revealed that immune fitness before the pandemic was the greatest predictor of the number and severity of COVID-19 symptoms (20.1% and 19.8%, respectively). Other significant predictors included immune fitness during the lockdown (5.5% and 7.1%, respectively), and having underlying diseases (0.4% and 0.5%, respectively). In the COTEST study, for those who tested positive for SARS-CoV-2, immune fitness before the pandemic was the single predictor of the number (27.2%) and severity (33.1%) of COVID-19 symptoms during the pandemic. In conclusion, for those who tested positive for SARS-CoV-2, immune fitness before the pandemic was the strongest predictor of the number and severity of COVID-19 symptoms during the pandemic. Therefore, the development of strategies to maintain an adequate immune fitness must be regarded as an essential component of pandemic preparedness.

Living Alone or Together During Lockdown: Association with Mood, Immune Fitness and Experiencing COVID-19 Symptoms.

PURPOSE: The aim of this study was to evaluate whether or not living alone or together throughout the lockdown had an impact on mood, perceived immune fitness, as well as the presence and severity of COVID-19 symptoms. METHODS: N = 505 participants completed an online survey, which included questions on living situations, as well as mood, perceived immune fitness and COVID-19 symptom presence and severity. These factors were assessed retrospectively for the time periods before and during the COVID-19 pandemic. RESULTS: An overall decrease in mood was observed for both those living alone and together during the lockdown period. However, significantly larger increases in feelings of loneliness were observed for the group living alone. Furthermore, both groups reported decreases in perceived immune fitness, whereas only the group living alone reported a significant increase in COVID-19 symptom presence and severity. Moreover, significant correlations were found between perceived immune fitness, anxiety, and loneliness. These correlations were strongest in the group living alone. Lastly, positive correlations were found between perceived immune fitness and mood outcomes with being active, optimistic and the ability to cope with stress. Increased optimism, being more active and the adequate ability to cope with stress were associated with a reduced negative impact on perceived immune fitness. CONCLUSION: The first COVID-19 lockdown period in the Netherlands was a challenging period for both people who lived alone and those living together, resulting in decreases in mood and poorer perceived immune fitness. Those living alone were, however, more heavily impacted by the lockdown restrictions. This was further reflected by the increased presence and severity of COVID-19 symptoms in people who lived alone during the first COVID-19 lockdown in The Netherlands.

In Vitro Assessment of the Antiviral Activity of Ketotifen, Indomethacin and Naproxen, Alone and in Combination, against SARS-CoV-2.

The 2019 coronavirus infectious disease (COVID-19) is caused by infection with the new severe acute respiratory syndrome coronavirus (SARS-CoV-2). Currently, the treatment options for COVID-19 are limited. The purpose of the experiments presented here was to investigate the effectiveness of ketotifen, naproxen and indomethacin, alone or in combination, in reducing SARS-CoV-2 replication. In addition, the cytotoxicity of the drugs was evaluated. The findings showed that the combination of ketotifen with indomethacin (SJP-002C) or naproxen both reduce viral yield. Compared to ketotifen alone (60% inhibition at EC50), an increase in percentage inhibition of SARS-CoV-2 to 79%, 83% and 93% was found when co-administered with 25, 50 and 100 µM indomethacin, respectively. Compared to ketotifen alone, an increase in percentage inhibition of SARS-CoV-2 to 68%, 68% and 92% was found when co-administered with 25, 50 and 100 µM naproxen, respectively. For both drug combinations the observations suggest an additive or synergistic effect, compared to administering the drugs alone. No cytotoxic effects were observed for the administered dosages of ketotifen, naproxen, and indomethacin. Further research is warranted to investigate the efficacy of the combination of ketotifen with indomethacin (SJP-002C) or naproxen in the treatment of SARS-CoV-2 infection in humans.
