Introduction: Poor response to ovarian stimulation is still a major problem in IVF. The study presents a new stimulation protocol evaluated in a suppopulation of very difficult young poor ovarian responders.
Material And Methods: The study consists in two sections. The first includes data from a randomized controlled study involving forty-three young patients with a poor ovarian response in at least two previous cycles (intended as cycle cancellation or with ≤3 collected oocytes). Patients were randomized in two groups: group A (control) received FSH (400 IU/day), while group B received the new stimulation protocol consisting in a sequential association of 150 IU r-LH for 4 days followed by 400 IU r-FSH/after downregulation with daily GnRh agonist. The second includes data from the overall results in 65 patients treated with the new protocol compared to their previous performance with conventional cycles (historical control).
Results: Both in the RCT and in the historical control study, LH pretreatment was able to decrease the cancellation rate, to improve the in vitro performance, and to significantly increase the live birth rates.
Conclusions: LH pretreatment improved oocyte quantity and quality in young repeated poor responders selected in accordance with the Bologna criteria.

The Oxford hip score demonstrates moderate ceiling effects at one and two years after total hip arthroplasty: which patients are at risk and does it matter?
Eur J Orthop Surg Traumatol

Background: The aim was to assess whether the postoperative Oxford Hip Score (OHS) demonstrated a ceiling effect at 1 or 2 years after total hip arthroplasty (THA) and to identify which patients are more likely to achieve a ceiling score and whether this limits assessment of their outcome.
Methods: A retrospective cohort of 7871 patients undergoing primary THA was identified from an established arthroplasty database. Patient demographics, ASA grade, socioeconomic status, OHS and EuroQol questionnaire were collected preoperatively and at 1 and 2 years postoperatively.

Objectives: (1) To determine the life satisfaction (LS) of members of a cohort study of aging men; (2) to determine if LS predicts death at various ages amongst members of a cohort study.
Methods: We analyzed a prospective cohort study of men who qualified for air crew training in the Second World War. In 2005, 860 participants with a mean age of 85, were alive and responded to the annual questionnaire - which is sent to participants living in the community.

Evidence suggests that older adults who survived COVID-19 were exposed to greater functional dependence in their daily living activities. This study aims to examine the prevalence of functional dependence and associated factors among Brazilian older people with functional dependence 12 months after COVID-19 infection. A cross-sectional study was carried out involving people aged 60 years or older in the state of Paraná, Brazil.

Correct nutrition during pregnancy is key to guaranteeing success at this stage of a woman's life, and nutritional education is the fundamental tool for achieving this. Studies carried out in different countries indicate that pregnant women do not comply with dietary and nutritional recommendations. Given the lack of evidence available in Spain and the importance of this knowledge to be able to assess the need for nutritional intervention in this group, the aim of this study focused on the current status of the issue in Spain: the quality of the diet of Spanish pregnant women and its conditioning factors.
