Clinical psychology

The study aimed to investigate the basic aspects of quality of life and relation to disease in patients with malignant or premalignant bone tumors. Study participants (N=82) were aged 18 to 67 years (average age 34 ± 2 years). They were separated into three groups depending on diagnosis: patients with osteosarcoma, patients with giant cell tumor and patients with chondrosarcoma. The SF-36 Health Status Survey and the Quality of Life Questionnaire - Core 30 with Bone Metastasis (BM22) Module were used to assess patient quality of life. The type of relation to disease method (TOBOL) was used to determine the relation to disease of the patients.

According to the results of the quality of life study, patients with giant cell tumor exhibited the highest degree of limiting physical activity and reduced social functioning, the greatest financial difficulties and more pain sites than either patients with osteosarcoma or patients with chondrosarcoma. The study of relation to disease revealed that all studied groups of patients were susceptible to ergopathic and sensitive types of relation to disease. Moreover, patients with giant cell tumor experienced increased levels of tension and irritability with respect to relation to disease and treatment, while patients with chondrosarcoma were more susceptible to anxiety and hypochondria with respect to relation to disease.

Patients with different types of bone tumors have different experiences with respect to their physical and mental health, their social functioning and their general health. The results of the study may be useful in developing individualized psychological aid programs for patients with malignant and premalignant bone tumors.

An in vitro fertilization (IVF) pregnancy is stressful both financially and emotionally. Patients undergoing an IVF procedure often have already had infertility and reproductive losses. Pregnancy through IVF involves the increased risk of various medical complications. Experts around the world are actively engaged in studying the specifics of the mental state of participants in IVF programs during pregnancy. Of critical importance is the issue of providing psychological support for couples who are preparing for and who have received an IVF pregnancy. 

The aim of our research was to investigate the mental state of women participating in an IVF program. The study involved 224 pregnant women in the second and third trimesters: 62 women with an IVF pregnancy and 162 women who conceived naturally. The study took place at the Kulakov Scientific Center for Obstetrics, Gynecology, and Perinatology in Moscow, Russia. All the study participants had encountered medical complications during their pregnancy. No significant differences were identified in mental well-being in the two groups; this finding suggests that somatic complications during pregnancy are a general source of anxiety regardless of the reason for their occurrence. The second and third trimesters of pregnancy register increased anxiety levels associated with experiences of reproductive loss and the presence of physical problems. The main resources of a woman’s personality that contribute to her self-confidence and mental stability are her professional employment and flexible behavior.

A major risk factor for late-onset Alzheimer’s type dementia (DAT) is the carriage of the ε4 allele of the apolipoprotein E (ApoE) gene. Identifying cognitive deficits in healthy ApoE-ε4 carriers is valuable in order to develop interventions to prevent them from developing DAT. Existing evidence about cognitive deficits in the domains of episodic memory and cognitive control specific to ApoE-ε4 is contradictory.

The objective of our research was to assess episodic memory and cognitive control in healthy ApoE-ε4 carriers.

Cognitively healthy ApoE-ε4 carriers (13 ε4/ε4 heterozygotes) and noncarriers (22 ε3/ε3 homozygotes), who were matched on age and family history of DAT, were compared on episodic-memory and cognitive-control tasks. Episodic-memory tasks were verbal and visual recognition tasks with a systematic variation of distractor-to-target similarity. Executive functions were assessed by a task for updating working memory, an inhibition task, and a switching task. Working-memory capacity was also assessed.

The results showed that executive functions were generally not impaired in the carriers, but carriers showed a specific increase in accuracy-related switch costs. Workingmemory capacity was not reduced in the carriers. In the domain of episodic memory, the carriers were found to make more errors with phonetic distractors in the verbal episodicmemory task. They also tended to make more errors with visually dissimilar distractors in the visual episodic-memory task.

The results are indicative of an episodic-memory deficit specific to the carriage of ApoE-ε4. This deficit may be driven either by deficits in storage or by deficits in the encoding of the to-be-remembered material. Contradictory results concerning the presence of an episodic-memory deficit obtained in previous studies may stem from small effect sizes, the use of specific materials, and the employment of attention-intensive encoding strategies. The carriers also showed a switching deficit that possibly is related to difficulty in retrieving task rules from episodic memory. Existing empirical contradictions concerning the presence of an executive deficit in carriers may in part depend on the extent to which tasks used to assess an executive deficit draw on the switching function. In this study, there was no general executive deficit in the carriers of ApoE-ε4.
