Considering the frequency and severity of olfactory disorders associated with SARS-CoV-2 infection, attention to the olfactory loss has expanded. The aim of our study was to assess of smell disturbances 6 months after COVID-19. The study population consisted of 2 groups: 196 Post-COVID-19 patients who were hospitalized because of COVID-19, control sample-130 patients without reported smell disorders from general population-Bialystok PLUS study. People from both groups were asked to participate in the Sniffin Sticks Test (half year after the disease). Sniffin Sticks Test consisted of 12 standardized smell samples. The participant's test score was counted based on correct scent recognition. Middle/older age was related with lower likelihood of olfaction recovery. The biggest differences in recognition of particular fragrances were observed for: orange and lemon, lemon and coffee (p.adj < 0.001). Patients had the greatest problem in assessing smell of lemon. The comparison of scores between Delta, Omicron, Wild Type, Wild Type Alpha waves showed statistically significant difference between Delta and Wild Type waves (p = 0.006). Duration of the disease (r = 0.218), age (r = -0.253), IL-6 (r = -0.281) showed significant negative correlations with the score. Statistically significant variables in the case of smell disorders were Omicron wave (CI = 0.045-0.902; P = 0.046) and Wild Type wave (CI = 0.135-0.716; P = 0.007) compared to Delta wave reference. Moreover, patients with PLT count below 150 000/μl had greater olfactory disorders than those with PLT count over 150 000/μl. There are: smell differences between post-COVID-19 patients and healthy population; statistically significant difference between Delta and Wild Type waves in Post-COVID-19 group in score of the Sniffin Sticks Test. Smell disturbances depend on the age, cognitive impairments, clinical characteristics of the COVID-19 disease and sex of the patient., (© 2024. The Author(s).)

Background: Coronavirus disease 2019 (COVID-19) has permanently changed the world. Despite having been a pandemic for nearly 3 years, the mid- and long-term complications of this disease, including endocrine disorders, remain unclear. Our study aimed to evaluate the lasting effects of COVID-19 on the endocrine system 6 months after initial infection., Methods: We compared patients who underwent COVID-19 to age- and sex-matched subjects from a population-based study conducted before the pandemic. We evaluated differences in multiple parameters related to metabolism and the endocrine system including fasting glucose, insulin, lipids, body composition, thyroid stimulating hormone (TSH), free thyroxine (fT4), free triiodothyronine (fT3), anti-thyroglobulin (aTG) and anti-thyroid peroxidase (aTPO) antibodies, prolactin, cortisol, testosterone, and estradiol., Results: We found significantly lower levels of fT3 and fT4, accompanied by higher levels of TSH and aTPO antibodies, in COVID-19 survivors. Moreover, we found that patients who underwent SARS-CoV2 infection had higher levels of prolactin and lower levels of testosterone than controls. Interestingly, differences in testosterone levels were observed only in male subjects. We did not detect significant differences in body composition or metabolic and glycemic parameters between cases and controls, except for significantly higher values of the HOMA2-B index in COVID-19 survivors., Conclusion: Our study indicates that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection might have long-term consequences on the endocrine system, including the suppressed function of the thyroid gland, prolactin, and male sex hormone secretion. Moreover, we showed that in a 6-month follow-up, COVID-19 had no consequences on glycemic parameters, lipid profiles, liver function, body composition, cortisol levels, and estradiol levels., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Szczerbiński, Okruszko, Szabłowski, Sołomacha, Sowa, Kiszkiel, Gościk, Krętowski, Moniuszko-Malinowska and Kamiński.)

The outbreak of the COVID-19 pandemic caused the healthcare system to drastically reduce in-person visits and suddenly switch to telemedicine services to provide clinical care to patients. The implementation of teleconsultation in medical facilities was a novelty for most Polish patients. In Poland, the main telehealth services were provided in the form of telephone consultations. The aim of this study is to determine patients' perceptions of telemedicine in the context of their experiences with the healthcare system during the COVID-19 pandemic. In this study, we presented how the evaluation of telemedicine services from the perspective of patients in Poland changed in the context of the ongoing pandemic. We conducted two surveys (year by year) on a representative quota sample of the Polish population (N = 623). This ensured that our observations took into account the evolution of views on telemedicine over time. We confirmed the well-known relationship that innovations introduced in the healthcare sector require a longer period of adaptation. We also identified significant concerns that limit the positive perception of telemedicine and compared them with experiences described in other countries.

To assess the frequency of persisting symptoms after SARS-CoV-2 infection and assessment of the effects of COVID-19 pandemic on selected parameters of self-reported health status and well-being half a year after the disease. The study population consisted of 3 groups: post-COVID-19 group I-172 patients; group II-172 patients with chronic disease, who have not suffered from COVID-19; group III-81 patients from a population study cohort-Bialystok PLUS. A standardized interview questionnaire was used to collect data in the three groups using the CATI (computer assisted telephone interviewing) technique. Interviews were conducted between October 2020 and January 2021, thus during the second wave of the pandemic in Poland. The subjective state of health in comparison with the state of health before the COVID-19 pandemic deteriorated in COVID-19 convalescents. Patients, who suffered from symptomatic COVID-19 were more prone to nervousness, anxiousness, tension than patients with oligosymptomatic course of the disease. Moreover, anxiety, fear and irritability were more frequent in Group I and II in comparison to Group III, whereas Group I and II did not differ significantly. The decrease in physical activity observed in COVID-19 patients mirrored the changes in general population. The most frequent persistent symptoms after COVID-19 are: general malaise, cough, smell and taste disorder, dyspnea. COVID-19 convalescents who experienced symptomatic disease are more prone to development of nervousness, anxiousness, tension and anxiety than patients with oligosymptomatic course of the disease. Females and younger patients who suffered from COVID-19 are more prone to development of mental distress than healthy population. No significant differences between COVID-19 convalescents and healthy population was observed as far as the attitude towards physical activity is concerned., (© 2022. The Author(s).)

Obesity and diabetes are associated with severe outcomes of coronavirus disease (COVID-19). Vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have been proven protective against infection and severe COVID-19. However, the immune response of metabolically burdened individuals to the vaccines remains unclear. Thus, we aimed to assess whether the metabolic status of individuals affects their humoral immune responses to the vaccination. Moreover, we evaluated whether the interval between the first two doses influenced antibody concentration. Sixty-seven individuals (21 males, 46 females) were vaccinated with the BNT162b2 mRNA COVID-19 vaccine. Fifty-four individuals were vaccinated with the second dose after 3 weeks and 13 after 5 weeks. We measured the antibody titers in all participants during the 19-week follow-up period. Patients diagnosed with COVID-19 were excluded. In the 5-week interval group, a significantly higher level of maximal antibody titers was observed. However, there were no differences in antibody concentrations after 19 weeks and no significant correlation between cardiometabolic factors and humoral response. The elongation of second-dose timing to 5 weeks leads to a higher acute antibody response but does not change long-term levels of antibody titers. Moreover, dysregulation of metabolic parameters does not lead to a diminished immune response to vaccination. [ABSTRACT FROM AUTHOR]

Since the declaration of the SARS-CoV-2 pandemic confirmed by World Health Organization, work on the development of vaccines has been stimulated. When vaccines are commonly available, a major problem is persistent vaccine hesitancy in many European countries. The main goal of our study was to understand the multidimensional factors inducing this phenomenon in Poland. Our study was carried out at the third wave's peak of the pandemic, with record rates of daily cases and deaths associated with COVID-19. The results indicate that vaccine hesitancy/acceptability should always be considered in an interdisciplinary manner and according to identified factors where most negative attitudes could be altered. Our analyses included the assessment of a representative quota sample of adult Poles (N = 1000). The vaccine hesitancy in the studied group reached 49.2%. We performed stepwise logistic regression modeling to analyze variables set into six trajectories (groups) predicting the willingness to vaccinate. Apart from typical, socio-demographic and economic determinants, we identified the fear of vaccines' side effects, beliefs in conspiracy theories and physical fitness. We were also able to establish the order of importance of factors used in a full model of all impact trajectories. [ABSTRACT FROM AUTHOR]
