Combating Loneliness in Older Adults during the COVID-19 Pandemic: Findings from a Volunteer-Based Program in Greece.

The COVID-19 pandemic has exacerbated the feeling of loneliness, especially among older adults. This study aims to investigate any association between COVID-19 cases in Greece and the number of Loneliness Helpline calls at the Friendship at Every Age program and to assess whether the interconnection part of the program, which interconnects older adults with volunteers, can combat loneliness/social isolation in older adults. This is a supportive, volunteer-based, social intervention program.

Health-Related Quality of Life in Childhood and Adolescence: The Interrelation with Level of Adherence to Mediterranean Diet and Dietary Trajectories: Highlights from the DIATROFI Program (2021-2022).

Children's dietary habits can have a key role in contributing to an improvement in their Health-Related Quality of Life (HRQoL). This study aims to assess the connection between Mediterranean diet adherence and HRQoL in a sample of Greek students, utilizing data from the DIATROFI program. The parents of 3774 students (mean age 7.

Incidental finding of unilateral complete duplication of ureter in a patient with large ureteric calculus obstructing both left limbs.

Duplication of the ureter is a common congenital malformation, which unfortunately may be accompanied by unpleasant and challenging pathologies. Hereby, a rare case of a patient with obstructive urolithiasis secondary to undiagnosed complete ureteral duplication is presented. A single large calculus in the vesicoureteral junction was obstructing both duplicated ureters.

Redox Status and Hematological Variables in Melatonin-Treated Ewes during Early Pregnancy under Heat Stress.

The preovulatory follicles and preimplantation stage embryos are found to be rather sensitive to heat stress due to their low potential for scavenging reactive oxygen species (ROS). The aim of the present study was to assess the impact of melatonin administration on redox status and hematological variables during the preovulatory period and early stages of embryogenesis in heat-stressed ewes in vivo. Forty Karagouniko-breed ewes were divided in two groups, the melatonin (M, n = 20) group and control (C, n = 20) one.

Human ghrelin decreases pituitary response to GnRH in superovulated ewes.

In addition to its metabolic role, ghrelin has been found to suppress luteinizing hormone secretion in many species acting mainly at the hypothalamic level. The objectives of the present study were to test the hypothesis that besides its effects on the hypothalamic level, ghrelin exerts a direct action on the pituitary. Twelve cycling ewes were synchronized, using progestagen intravaginal sponges and superovulated using eCG.
