The characteristics of olfactory memory during development were investigated and the hypothesis that the pleasantness of smells may be affected by previous associations with pleasant or unpleasant objects or events was tested. This type of emotional memory was compared in the immediate and long-term recognition of olfactory stimuli. Children from three different age groups (mean ages: 6 years 6 months; 8 years 9 months; and 10 years 5 months) were subdivided into two groups. One group was presented with six different odours, each with a slide depicting a pleasant picture. The other group was presented with the odours accompanied by unpleasant pictures. Immediately after stimulus presentation the subjects underwent a recognition test. One month later the subjects underwent a second recognition test, at the end of which they were required to give an evaluation of the pleasantness of each odour on a nine-point scale. At no age level did the pictures matched to the odours affect the recognition score. Olfactory memory varied with age, chiefly because memory decay increased with age, perhaps because of greater proactive interference. With increasing age more rapid decay was set against better immediate recognition. The hypothesis that the hedonic characteristics of odours are partially learned and are affected by events experienced in other modalities was supported.

In order to determine possible trends in the dynamics and characterological structure of personality in the General population caused by the COVID-19 pandemic, which is a long-term strong stressful effect and clinically and psychopathologically comparable to chronic personality changes after experiencing a disaster, the conditions predisposing to personal transformation, including clinical and prognostic patterns, are analyzed. The age-dependent nature of these changes is shown, and a number of features identified for different age groups are discussed.

Original Survey

Quality of life (QoL) is an important parameter that affects the choice of therapy. Assessment of QoL and satisfaction with therapy using the rtCGM in children with T1D aged < 7 years was conducted. The study group consisted of 38 children with T1D aged < 7 years (34% aged 2–4, 66% aged 5–7 years), HbA1c: 6.53 ± 0.63%, duration of diabetes: 2.6 ± 1.6 years, treated with an rtCGM-augmented insulin pump for 1.92 ± 1.15 years. Two anonymous surveys were conducted: a. PedsQL3.0 diabetes standardized questionnaire—QoL assessment among age groups: 2–4/5–7 years. b. An original survey assessing the CGM use satisfaction. The mean scores in PedsQL3.0: communication 75%, worries 30%, treatment 70%, and problems associated with diabetes 65%. The QoL scale is: 0–19% very low, 20–39% low, 40–59% moderate, 60–79% high, 80–100% very high. The most frequently reported concerns were long-term diabetes complications and prick pain. Satisfaction with CGM use was high (68% in group aged 5–7 and 92% 2–4 years). Twenty-seven (71%) caregivers confirmed the positive effect of CGM on sleep. During the use of rtCGM a high quality of life was reported, and the quality of sleep in their caregivers was increased.

Olfactory neuroblastoma (ONB) is a rare neuroepithelial-derived malignancy that usually presents in the nasal cavity. The rarity of ONB has led to conflicting reports regarding associations of patient age and ONB survival and outcome. Moreover, long-term outcomes of chemotherapy and other treatment modalities are speculated. Here, we aimed to compare survival outcomes across age groups through time and determine associations between treatment modality and survival. In this retrospective population-based study, we analyzed the SEER 2000–2016 Database for patients with ONB tumors. Using Kaplan–Meier survival analysis, a significant effect of age and cancer-specific survival (CSS) was observed; geriatric ONB patients had the lowest CSS overall. Generalized linear models and survival analyses demonstrated that CSS of the pediatric patient population was similar to the geriatric group through 100 months but plateaued thereafter and was the highest of all age groups. Radiation and surgery were associated with increased CSS, while chemotherapy was associated with decreased CSS. GLM results showed that tumor grade, stage and lymph node involvement had no CSS associations with age or treatment modality. Our results provide insight for future investigations of long-term outcomes associated with ONB patient age and treatment modality, and we conclude that survival statistics of ONB patients should be analyzed in terms of trends through time rather than fixed in time.

Therapeutic Success

Abstract Elucidation of the pathogenesis of chronic myeloid leukemia (CML) and the introduction of tyrosine kinase inhibitors (TKIs) has transformed this disease from being invariably fatal to being the type of leukemia with the best prognosis. Median survival associated with CML is estimated at > 20 years. Nevertheless, blast crisis occurs at an incidence of 1%-2% per year, and once this has occurred, treatment options are limited and survival is short. Due to the overall therapeutic success, the prevalence of CML is gradually increasing. The optimal management of this disease includes access to modern therapies and standardized surveillance methods for all patients, which will certainly create challenges. Furthermore, all available TKIs show mild but frequent side effects that may require symptomatic therapy. Adherence to therapy is the key prerequisite for efficacy of the drugs and for long-term success. Comprehensive information on the nature of the disease and the need for the continuous treatment using the appropriate dosages and timely information on efficacy data are key factors for optimal compliance. Standardized laboratory methods are required to provide optimal surveillance according to current recommendations. CML occurs in all age groups. Despite a median age of 55-60 years, particular challenges are the management of the disease in children, young women with the wish to get pregnant, and older patients. The main challenges in the long-term management of CML patients are discussed in this review.

The Welfare State

As the crisis turns into long-term economic downturn, younger age-groups in Europe seem to be hit with higher levels of unemployment while the welfare state is steadily shrinking. The young have suddenly become a social group united by collective material interests, but does this translate into a sense of a collective political interest? The paper examines to what extent the dominant class-based social science of the post-war years can help us understand the politics of age-groups. The analysis highlights four changes since post-war years: the workplace has changed, impacting socialization; modern media has changed, impacting mobilization; the political landscape is fairly institutionalized, tempering the possibilities for new political concerns to find voice; and those who would define and articulate the political priorities of the young are leaving the Old Continent.

Se Status

Se is an essential nutrient that provides antioxidant protection in concert with vitamin E. Several selenoproteins have been identified, but only one, SeGSHpx, has a known function, that of neutralizing toxic hydroperoxides. Plasma Se concentration, being responsive to changes in Se intake, is the most practical and widely used measure of nutritional Se status. The plasma Se concentrations of the majority of healthy infants and children fall within the range of 50 to 150 µg/L. Although SeGSHpx activity measures the metabolically functional form of Se, the lack of a standardized analytical method has limited its usefulness as an index of nutritional Se status. Se deficiency was first observed in animals, but it is now recognized to occur in humans. Two human diseases associated with severe nutritional Se deficiency have been reported from China: a juvenile cardiomyopathy named Keshan disease and a chondrodystrophy named Kaschin-Beck disease. Long-term TPN, which provides negligible amounts of intrinsic Se, has been demonstrated in some cases to result in biochemical and clinical impairment. Although there are no consistent signs and symptoms characteristic of TPN-associated Se deficiency, in addition to the low blood selenium levels, some patients will experience leg muscle pain and altered serum transaminase and creatine kinase activities. These manifestations of Se deficiency usually take years to develop. Recent information about the amount of dietary Se needed to maximize plasma SeGSHpx activity in adult men has allowed for better estimates of the Se requirement for humans. Recommended daily dietary allowances published recently by the National Academy of Sciences have been revised for infants and children in this paper by making appropriate adjustments for the protein requirements of these age-groups. These recommended intakes for Se can generally be met by consuming adequate amounts of cereals, meat, eggs, dairy products, human milk, and infant formula, which are good sources of highly available Se and are of low risk of providing excess amounts of Se. Suboptimal Se intakes by pregnant women may predispose their infants to low Se status at birth, which in turn may affect the infants' ability to maintain adequate Se status during the first few months of life. In those situations where protein intake is restricted, such as in phenylketonuria and maple syrup urine disease, Se-supplemented formulas should be used. The most critical situation for Se supplementation is in pediatric patients receiving long-term TPN therapy. When supplementing with Se, consideration must be given to the amount and form of Se to be used; with long-term TPN therapy, plasma Se levels should be monitored.

На нашей планете живeт около 1,3 млрд человек с такими нарушениями зрительного анализатора, как катаракта и глаукома, распространенность которых значимо выше у лиц пожилого возраста. Заболевания глаз остаются глобальной медикосоциальной и экономической проблемой, что связано как с прогрессированием болезни вплоть до слепоты, так и с отсутствием методов патогенетической терапии. Проведен ретроспективный анализ многолетней динамики и структуры случаев офтальмологических заболеваний у пациентов, проходивших лечение в многопрофильной больнице. Описана возрастная и нозологическая структура офтальмологических заболеваний. Выявлены закономерные особенности структуры заболеваний относительно разных возрастных групп, также обнаружены закономерности в их динамике. About 1,3 billion people live on our planet with visual disorders such as cataract and glaucoma, the prevalence of which is significantly higher in the elderlypopulation. Eye diseases remain a global medical, social and economic problem, associated with both the progression of the disease to blindness and the lack of pathogenetic therapy methods. A retrospective analysis of the long-term dynamics and structure of cases of ophthalmological diseases of patients treated in a large multidisciplinary hospital was carried out. The age and nosological structure of eye diseases is described. Natural features of the structure of diseases relative to different age groups have been revealed, as well as patterns in dynamics have been found.

Heritable Effects

Abstract Most surgical procedures require general anesthesia, which is a reversible deep sedation state lacking all perception. The induction of this state is possible because of complex molecular and neuronal network actions of general anesthetics (GAs) and other pharmacological agents. Laboratory and clinical studies indicate that the effects of GAs may not be completely reversible upon anesthesia withdrawal. The long-term neurocognitive effects of GAs, especially when administered at the extremes of ages, are an increasingly recognized health concern and the subject of extensive laboratory and clinical research. Initial studies in rodents suggest that the adverse effects of GAs, whose actions involve enhancement of GABA type A receptor activity (GABAergic GAs), can also extend to future unexposed offspring. Importantly, experimental findings show that GABAergic GAs may induce heritable effects when administered from the early postnatal period to at least young adulthood, covering nearly all age groups that may have children after exposure to anesthesia. More studies are needed to understand when and how the clinical use of GAs in a large and growing population of patients can result in lower resilience to diseases in the even larger population of their unexposed offspring. This minireview is focused on the authors’ published results and data in the literature supporting the notion that GABAergic GAs, in particular sevoflurane, may upregulate systemic levels of stress and sex steroids and alter expressions of genes that are essential for the functioning of these steroid systems. The authors hypothesize that stress and sex steroids are involved in the mediation of sex-specific heritable effects of sevoflurane.

A modified and enhanced replication of an original experiment aimed to discover the extent of immediate and long-term vocabulary recall that exploited the mnemonic value of morphemes. Data for a sample size of 360 students were disaggregated based on age and gender using a pre/posttest instrument to determine immediate gains, and a long-term posttest (avg. 5.5 mos.) to determine the lasting effects of the intervention. Results revealed that older adults outperformed younger adults on all measures of the instrument and across all timeframes, with the oldest cohort significantly outperforming all other age groups, and women outperformed men, also on all measures across all timeframes, and significantly so on the vocabulary section of the instrument. Gain scores for all students across all measures and timeframes provide empirical support of the mnemonic value of morphemes when incorporated into a program offering direct vocabulary instruction for adult learners.
