Article Synopsis
- The study investigated the validity of a self-report questionnaire for hand eczema (HE) among Croatian hairdressers, aiming to determine how accurately apprentices could self-identify their symptoms.
- Results showed that the questionnaire had low sensitivity (7%-37%) but high specificity (≥95%), meaning it was better at identifying true negatives than true positives, with improvements noted over time as training progressed.
- The severity of HE signs was linked to better self-identification of symptoms, suggesting that further modifications and validation of the questionnaire are needed for adolescent populations.
Background: Preliminary data suggests that obesity might hasten the decline in mRNA vaccine-induced immunity against SARS-CoV-2. However, whether this renders individuals with obesity more susceptible to long COVID symptoms post-vaccination remains uncertain. Given sleep's critical role in immunity, exploring the associations between obesity, probable long COVID symptoms, and sleep disturbances is essential.

- - Accurate measurement of habitual sleep duration (HSD) is important for linking sleep to health, and this study compared two self-report methods (Method-Self and Method-MCTQ) to identify bias based on sleep quality (SQ) and social jetlag (SJL).
- - The findings from 10,268 participants indicated that Method-Self typically reported HSD as 42.41 minutes lower than Method-MCTQ, with greater bias observed in those with poorer sleep quality; the two methods exhibited very poor agreement overall.
- - The study suggests that including questions about sleep quality in surveys could help reduce estimation bias and improve the reliability of sleep-related health research, especially given the systematic errors found between the two methods examined
Article Synopsis
- The study explores how self-rated health (SRH) relates to sleep patterns in people who had COVID-19, suggesting that COVID-19 negatively impacts SRH and sleep quality.
- Participants from 16 countries were surveyed, with findings indicating that those infected with COVID-19 reported lower SRH scores, especially if their illness was severe.
- Changes in sleep duration after infection—both decreases and increases—were significantly linked to lower SRH scores, as well as increased fatigue and other health issues, highlighting the importance of sleep in recovery.
Objective: There is evidence of a strong association between insomnia and COVID-19, yet few studies have examined the relationship between insomnia and long COVID. This study aimed to investigate whether COVID-19 patients with pre-pandemic insomnia have a greater risk of developing long COVID and whether long COVID is in turn associated with higher incident rates of insomnia symptoms after infection.
Methods: Data were collected cross-sectionally (May-Dec 2021) as part of an international collaborative study involving participants from 16 countries.
Study Objectives: Preliminary evidence suggests that the risk of Long COVID is higher among people with pre-existing medical conditions. Based on its proven adjuvant role in immunity, habitual sleep duration may alter the risk of developing Long COVID. The objective of this study was to determine whether the odds of Long COVID are higher among those with pre-existing medical conditions, and whether the strength of this association varies by habitual sleep duration.

Thus, we hypothesized that short (<6 h) and long (>9 h) nighttime sleepers have a higher post-COVID risk than normal nighttime sleepers, despite two doses of mRNA vaccine (which has previously been linked to lower odds of long-lasting COVID-19 symptoms). Post-COVID was defined as experiencing at least one core COVID-19 symptom for at least three months (e.

Second, to investigate whether people regularly working in face-to-face settings during the pandemic exhibited a higher prevalence and severity of COVID-19 compared with those having no need to be in close contact with others at work.

The aim of the study was to assess the effectiveness of the specific design of a poisoning prevention intervention. This controlled before-after study followed Solomon design for educational interventions using two groups (the educational intervention group and the control group). Participants comprised parents of children attending kindergartens under the jurisdiction of the City of Zagreb and in the vicinity of Zagreb.

We analysed the data collected on 650 older workers (71 % employed) in the Wave 6 of the Survey of Health, Ageing and Retirement in Europe (SHARE). Unemployed workers reported symptoms of loneliness more often than the employed, while in rural areas unemployment was additionally associated with more pronounced symptoms of depression.

Contact Dermatitis
October 2019
Background: Hairdressing apprentices are at high risk for developing occupational contact dermatitis.
Objectives: The objective of this study was to analyse whether there are differences in skin health, skin protection and health-related quality of life between apprentices from two Croatian regions (Zagreb and Dalmatia).
Materials And Methods: Final-year hairdressing apprentices from Zagreb (n = 101) and Dalmatia (n = 77) were enrolled in the study.
