The ROPA (Reception of Oocytes from PArtner) method, also known as lesbian shared IVF (in vitro fertilization), is an assisted reproduction technique for female couples, in which one of the women provides the oocytes (genetic mother) and the other receives the embryo and gestates (gestational mother). As a double parented method, it is the only way lesbian women may biologically share motherhood. This is a narrative review of data concerning ROPA published in PubMed, Scopus, and Cochrane Library. A total of 35 articles were included, 10 about motivations for undergoing ROPA, 13 about ethics or legislation, 4 about motherhood, and 8 studies reporting clinical outcomes. Despite being used for more than a decade, there is a paucity of data regarding this technique in scientific literature. Most women choose this technique to share biological motherhood, but medical issues may also justify its use. Many ethical and legal issues are still to be solved. Despite the small number of studies, data regarding the outcomes of this technique and the resulting motherhood are reassuring.
Introduction: Proximal femur fragility fractures (PFFFs) are a growing worldwide concern. Recognizing the risk factors for subsequent fracture is essential for secondary prevention. This study aimed to analyze the risk factors for refracture and mortality rates in patients who suffered a PFFF.
Methods: Patients aged 65 years or older with PFFF who underwent surgical treatment during the year of 2017 in the same institution were retrospectively analyzed and at least four years after the index fracture were evaluated.
Results: From a total of 389 patients, 299 patients were included, with a median age of 83 years, and 81% female. Thirty-two (10.7%) suffered a refracture, with a mean time to refracture of 19.8 ± 14.80 months, being the female sex a risk factor for refracture (OR-4.69; CI [1.05-20.95]). The 1-year mortality rate was 15.4%. Seventy-three (24.4%) patients had previous fragility fractures. After the index fracture, 79% remained untreated for osteoporosis. No statistical association was found between antiosteoporotic treatment and refracture. Patients with refracture had higher prefracture functional level compared with patients without refracture (OR-1.33; CI [1.08-1.63]) and were discharged more often to rehabilitation units (31% versus 16%, P =.028). After 4 years of follow-up, patients with refracture had lower functional level compared with patients without. Chronic kidney disease was a risk factor (P = .029) for early refracture (<24 months).
Conclusion: Female sex and higher prefracture functional level may increase the risk of refracture. Chronic kidney disease was associated with a shorter refracture time. Despite having a PFFF or other fragility fractures, the majority of patients remained untreated for osteoporosis.
Background: Total knee arthroplasty (TKA) is one of the most frequently performed orthopedic procedures. The correct positioning and alignment of the components significantly affects prosthesis survival. Considering the current controversy regarding the target of postoperative alignment of TKA, this study evaluated the tension at tibial component interface using two numerical methods.
Methods: The stress of the prosthesis/bone interface of the proximal tibial component was evaluated using two numerical methods: the finite element method (FEM) and the new meshless method: natural neighbor radial point interpolation method (NNRPIM). The construction of the model was based on Zimmers NexGen LPS-Flex Mobile® prosthesis and simulated the forces by using a free-body diagram.
Results: Tibiofemoral mechanical axis (TFMA) for which a higher number of nodes are under optimal mechanical tension is between 1° valgus 2° varus. For values outside the interval, there are regions under the tibial plate at risk of bone absorption. At the extremities of the tibial plate of the prosthesis, both medial and lateral, independent of the alignment, are under a low stress. In all nodes evaluated for all TFMA, the values of the effective stresses were higher in the NNRPIM when compared with the FEM.
Conclusion: Through this study, we can corroborate that the optimal postoperative alignment is within the values that are currently considered of 0 ± 3° varus. It was verified that the meshless methods obtain smoother and more conservative results, which may make them safer when transposed to the clinical practice.

Background: The goal of human papillomavirus (HPV) vaccination is the decline of HPV related premalignant lesions, leading to prevention of cervical cancer. Vaccination against HPV is recommended until the age of 45 to prevent viral reinfections and reactivations. The aim of this study was to evaluate adhesion to HPV vaccination and their associated factors in adult women.
Methods: Cross-sectional study in two tertiary hospitals, with a questionnaire distributed to women born between 1974 and 1992, from September till November 2019. Data collected included sociodemographic information, clinical information, knowledge about HPV, and the HPV vaccine and data regarding vaccine recommendation. Factors associated with vaccination were searched by bivariate and multivariate statistical analysis.
Results: In 469 questionnaires, 25.4% (n = 119) women were vaccinated. The main reason for not vaccinating was the non-recommendation (n = 276; 70.2%). In bivariate analyses, vaccinated women were younger, predominantly not married, had higher educational level, and higher careers (P ≤ .001); an abnormal cytology, HPV infection or previous excision of the transformation zone were associated with a 3 to 4-fold increase in the odds of vaccination. Age, high-risk HPV infection, and knowing someone vaccinated remained factors independently associated with HPV vaccination in the multivariate analyses (P< .05). The recommendation of "vaccinate immediately" was independently associated with effectively doing it (P< .001).
Conclusions: HPV vaccination is associated with vaccine recommendation, especially if it is recommended to do immediately. These results reinforce the need of health professionals to be aware of the impact that their recommendation has on adhesion to HPV vaccination.
