Background Feelings of loneliness and social isolation are common among the elderly, affecting both health and wellbeing. The COVID-19 pandemic has altered social connections through health precautions, restrictions and other factors. However, limited research has been conducted on how older people’s health and wellbeing in different countries has been impacted by the COVID-19 pandemic. The aim of this study was to develop methodology that would allow us to compare elderly populations, aged 67 + in Latvia and Iceland, and to discuss the potential impact of diverging factors on the association between loneliness, social isolation and health.Methods Quantitative data on 420 respondents from Wave 8 of the Survey of Health, Ageing and Retirement in Europe (SHARE) was utilized in Latvia. Data on health and wellbeing of elderly in Iceland from a HL20 study with 1033 respondents was used to provide comparative analytic material for studying the differences between Latvia and Iceland, and within each country.Results The study revealed considerable differences between the countries regarding the frequency of loneliness and social isolation. About 80% of Latvian respondents felt socially isolated and 45% were lonely, compared to 42.7% socially isolated and 30% lonely Icelanders. In general, more elderly people in Latvia experienced difficulties than their peers in Iceland. Social isolation tends to differ across genders and age groups in both countries. This is related to marital and employment status, financial situation, and education. COVID-19 had a stronger deteriorating effect on mental and physical health among both lonely Latvian and Icelandic respondents. However, health deterioration was stronger amongst more socially isolated Icelanders compared to Latvians.Conclusions The study suggests that social isolation is a contributing factor and increases the risk of loneliness, which might have been enhanced by restrictions during the COVID-19 pandemic.

Background and Objectives: preoperative differentiation of enlarged parathyroid glands may be challenging in conventional B-mode ultrasound. The aim of our study was to analyse qualitative and quantitative characteristics of parathyroid gland lesions, using multiparametric ultrasound protocol—B-mode, Colour Doppler (CD), and contrast-enhanced ultrasound (CEUS)—and to evaluate correlation with morphology in patients with hyperparathyroidism (HPT). Materials and Methods: consecutive 75 patients with 88 parathyroid lesions and biochemically confirmed HPT prior to parathyroidectomy were enrolled in the prospective study. B-mode ultrasound, CD, and CEUS were performed with the subsequent qualitative and quantitative evaluation of acquired data. We used 1 mL or 2 mL of intravenous ultrasound contrast agent during the CEUS examination. Correlation with post-surgical morphology was evaluated. Results: seventy parathyroid adenomas were hypoechoic and well contoured with increased central echogenicity (44.3%), peripheral-central vascularization (47%), and polar feeding vessel (100%). Twelve hyperplasias presented with similar ultrasound appearance and were smaller in volume (p = 0.036). Hyperplasias had a tendency for homogenous, marked intense enhancement vs. peripherally enhanced adenomas with central wash-out in CEUS after quantitative analysis. No significant difference was observed in contrasting dynamics, regardless of contrast media volume use (1 mL vs. 2 mL). We achieved 90.9% sensitivity and 72.7% specificity, 93% positive predictive value (PPV), 87.3% negative predictive value (NPV), and 87.3% accuracy in the differentiation of parathyroid lesions prior to post-processing. In a quantitative lesion analysis, our sensitivity increased up to 98%, specificity 80%, PPV 98%, and NPV 80% with an accuracy of 96.4%. Conclusions: CEUS of parathyroid lesions shows potential in the differentiation of adenoma from hyperplasia, regardless of the amount of contrast media injected. The quantitative analysis improved the sensitivity and specificity of differentiation between parathyroid lesions. Hyperplasia was characterized by homogeneous enhancement, fast uptake, and homogeneous wash-out appearance; adenoma—by peripheral uptake, central wash-out, and reduced hemodynamics. The use of CEUS quantification methods are advised to improve the ultrasound diagnostic role in suspected parathyroid lesions.

The COVID-19 in the context of healthy ageing is associated with decline in body functional abilities and serious illness in older individuals. Regular assessment of ageing processes, including intrinsic capacity factors, provides an opportunity for better understanding of the individual’s functional abilities and vulnerabilities. Based on the data (2017–2020) from two waves (7 and 8) of the Survey of Health, Ageing and Retirement in Europe (SHARE), an evaluation and comparison of the intrinsic capacity factors of older individuals (50+ years) before and during COVID-19 was conducted, including data from 4422 individuals in Baltic countries (from Latvia – 648, Lithuania – 1079 and Estonia – 2695). Excellent or very good health status before the outbreak reported 35.3% respondents in Latvia, 54.9% in Lithuania and 45.3% in Estonia (p < 0.001). On worsened health status since the outbreak reported 7% respondents in Latvia, 13.8% in Lithuania and 5.9% in Estonia (p < 0.001). Feeling of nervousness, depression and loneliness during COVID-19 outbreak increased among all respondents, regardless of nationality and severity of symptoms before outbreak (p < 0.001). The results indicate that during COVID-19 outbreak respondents were experiencing deterioration in cognitive and psychological health. To maintain the level of individual’s functional abilities during situations like COVID-19 outbreak preventive actions are needed by promoting physical activities and social networks, especially for older individuals.

<p><em>Needs of parents during hospitalization of a child, during the health care process, are connected with the interaction of multilevel environment in the hospital setting. Created expert evaluation questionnaire and performed research serve as a basis for creation of the activity research questionnaire for parents of children and nurses employed in the health care field using acquired data. To heighten validity of the obtained data during each cycle of data analysis triangulated data acquisition methods were used</em><em>. During research of the needs of parents during hospitalization of their child following methods of triangulation were used</em><em>: data triangulation – quantitative and qualitative data obtained during research; sources: child</em><em>’</em><em>s parents and nurses</em><em>; triangulation of researchers</em><em> – author of the dissertation, scientific head of the dissertation, experts; triangulation of theories – sustainability/sustainable development, ecology of human development, </em><em>holistic health care model, system model; triangulation of </em><em>methods</em><em> – questionnaires, expert evaluations, analysis of qualitative data and thematic qualitative analysis</em><em>. During research the strategy of triangulation contains use of several sources of information</em><em>. Relatively autonomous research methods give purposeful answers to the research questions on needs of parents during hospitalization of a child. Data obtained during activity research indicate ability of the parents and health care teams to satisfy their needs. </em></p>
