Huggins and Hodges demonstrated the therapeutic effect of gonadal testosterone deprivation in the 1940s and therefore firmly established the concept that prostate cancer is a highly androgen-dependent disease. Since that time, hormonal therapy has undergone iterative advancement, from the types of gonadal testosterone deprivation to modalities that block the generation of adrenal and other extragonadal androgens, to those that directly bind and inhibit the androgen receptor (AR). The clinical states of prostate cancer are the product of a superimposition of these therapies with nonmetastatic advanced prostate cancer, as well as frankly metastatic disease. Today's standard of care for advanced prostate cancer includes gonadotropin-releasing hormone agonists (e.g., leuprolide), second-generation nonsteroidal AR antagonists (enzalutamide, apalutamide, and darolutamide) and the androgen biosynthesis inhibitor abiraterone. The purpose of this review is to provide an assessment of hormonal therapies for the various clinical states of prostate cancer. The advancement of today's standard of care will require an accounting of an individual's androgen physiology that also has recently recognized germline determinants of peripheral androgen metabolism, which include HSD3B1 inheritance.
Obtaining a natural breast mound shape contributes profoundly to a symmetrical and successful outcome in breast reconstruction.
This paper describes a new and efficient technique that enhances breast projection with natural ptosis in delayed breast reconstruction using abdominal free flaps, and compares it to the standard methods employed nowadays.
The charts of all patients who underwent delayed breast reconstruction using free abdominal perforator flaps were reviewed between 2007-2017. Three methods of breast reconstruction were compared undermining, de-epithelialization and the "Hug flap". In the newly described technique the caudal mastectomy skin was de-epithelialized and then the medial and lateral thirds were undermined and folded over to cover the central part (hug flap). 570 free abdominal flaps were performed in 490 patients for delayed breast reconstruction (410 unilateral breast reconstructions and 80 bilateral reconstructions).
The de-epithelization technique was the most commonly used (3east symmetry.In vitro maturation (IVM) is an assisted reproduction technique with reduced hormone-related side-effects. Several attempts to implement IVM in routine practice have failed, primarily due to its relatively low efficiency compared with conventional in vitro fertilization (IVF). Recently, capacitation (CAPA)-IVM-a novel two-step IVM method-has improved the embryology outcomes through synchronizing the oocyte nuclear and cytoplasmic maturation. learn more However, the efficiency gap between CAPA-IVM and conventional IVF is still noticeable especially in the numerical production of good quality embryos. Considering the importance of glucose for oocyte competence, its metabolization is studied within both in vivo and CAPA-IVM matured mouse cumulus-oocyte-complexes (COCs) through direct measurements in both cellular compartments, from transcriptional and translational perspectives, to reveal metabolic shortcomings within the CAPA-IVM COCs. These results confirmed that within in vivo COC, cumulus cells (CCs) are highly glycolytic, whereas oocytes, with low glycolytic activity, are deviating their glucose towards pentose phosphate pathway. No significant differences were observed in the CAPA-IVM oocytes compared with their in vivo counterparts. However, their CCs exhibited a precocious increase of glycolytic activity during the pre-maturation culture step and activity was decreased during the IVM step. Here, specific alterations in mouse COC glucose metabolism due to CAPA-IVM culture were characterized using direct measurements for the first time. learn more Present data show that, while CAPA-IVM CCs are able to utilize glucose, their ability to support oocytes during final maturation is impaired. link2 Future CAPA-IVM optimization strategies could focus on adjusting culture media energy substrate concentrations and/or implementing co-culture strategies.Low-carbohydrate diets have become a popular approach for weight loss in recent years. However, whether low-carbohydrate diets are associated with the risk of pancreatic cancer remains to be elucidated. Hence, we examined the association of low-carbohydrate diets with the risk of pancreatic cancer in a US population. A population-based cohort of 95 962 individuals was identified. A low-carbohydrate-diet score was calculated to quantify adherence to this dietary pattern, with higher scores indicating greater adherence. Cox regression was used to calculate risk estimate for the association of the low-carbohydrate-diet score with the risk of pancreatic cancer. Subgroup analysis was used to identify the potential effect modifiers. After an average follow-up of 8.87 years (875856.9 person-years), we documented a total of 351 pancreatic cancer cases. In the fully adjusted model, the highest versus the lowest quartiles of the overall low-carbohydrate-diet score were found to be associated with a reduced risk of pancreatic cancer (hazard ratioquartile 4 versus 1 0.61; 95% confidence interval 0.45, 0.82; Ptrend less then 0.001). Subgroup analysis found that the inverse association of low-carbohydrate diets with the risk of pancreatic cancer was more pronounced in individuals aged ≥65 years than in those aged less then 65 years (Pinteraction = 0.015). learn more Similar results were obtained for animal and vegetable low-carbohydrate-diet scores. In conclusion, low-carbohydrate diets, regardless of the type of protein and fat, are associated with a lower risk of pancreatic cancer in the US population, suggesting that adherence to low-carbohydrate diets may be beneficial for pancreatic cancer prevention. Future studies should validate our findings in other populations.
lifestyle-related secondary prevention reduces cardiac events and is recommended irrespective of age. However, motivation may be influenced by age and disease progression.
to explore older cardiac patients' perspectives toward lifestyle-related secondary prevention after a hospital admission.
a generic qualitative design was used. Semi-structured interviews were performed with cardiac patients ≥ 70years within 3months after a hospital admission. The interview guide was based on the Attitudes, Social influence and self-Efficacy (ASE) model. All interviews were analysed using thematic analysis.
eight themes emerged which were linked to the determinants of the ASE-model. The three themes (i) Perspectives are determined by general health and habits, (ii) feeling the threat as a motivator and (iii) balancing between health benefits and quality of life (QoL), were linked to attitude. Regarding social influence, the themes (iv) feeling both encouraged and hindered by family members, and (v) the healthcare prty. Patients' preferences and patient-centred outcomes focusing on QoL and functional independence may be the starting point when healthcare professionals discuss lifestyle modification in older patients. The involvement of family members may help patients to integrate lifestyle-related secondary prevention in daily life.
Hyperglycemia at admission has been demonstrated to exacerbate the outcomes of coronavirus disease 2019 (COVID-19) but a meta-analysis is lacking to further confirm this hypothesis. The purpose of this meta-analysis was to summarize the evidence on the association between hyperglycemia at admission and the development of COVID-19.
Four databases namely, PubMed, Web of Science, Embase and Cochrane Library, were screened for eligible studies. STATA software was utilized to pool data for this meta-analysis. link2 The primary outcomes included mortality and severity. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated with random-effects models, and the quality of evidence was appraised by the Newcastle-Ottawa Scale (NOS). This meta-analysis was prospectively registered online on PROSPERO, CRD42020191763.
Sixteen observational studies with 6386 COVID-19 patients relating hyperglycemia at admission to COVID-19 outcomes were included. The overall data demonstrated that, compared with the control, the hyperglycemia at admission group was more likely to have increased mortality (OR = 3.45, 95% CI, 2.26-5.26) and severe/critical complications (OR = 2.08, 95% CI, 1.45-2.99) of COVID-19.
Hyperglycemia at admission in COVID-19 patients may be a strong predictor of mortality and complications.

Facial feminization surgery (FFS) includes several osseous modifications of the forehead, mandible and chin, procedures which require precision in order to provide the patient with a satisfactory result. Mispositioned osteotomies can lead to serious complications and bad aesthetic outcomes. Surgical cutting guides are commonly used in plastic and maxillofacial surgery to improve safety and accuracy. link3 Yet, there is no report in the literature on the clinical application of cutting guides in FFS.
The aim of this paper is to assess the safety and accuracy of custom surgical cutting guides in FFS procedures.
A prospective follow-up of forty-five patients regarding FFS with preoperative virtual planning and 3D custom-made surgical guides for anterior frontal sinus wall setback, mandibular angle reduction and/or osseous genioplasty was conducted. link2 Accuracy (superimposing preoperative data on postoperative data by global registration with a 1mm margin of error), safety (intradural intrusion for the forehead procedures and injury of the infra alveolar nerve for chin and mandibular angles) and patient satisfaction were assessed.
A total of 133 procedures were documented. link3 There was no cerebrospinal fluid leak on the forehead procedures nor any infra alveolar nerve or tooth root injury on both chin and mandibular angle operations (safety, 100%). Accuracy was 90.80 % on the forehead (n=25), 85.72% on the mandibular angles (n=44) and 96.20% on the chin (n=26). An overall satisfaction of 94.40% was recorded.
Custom-made surgical cutting guides could be a safe and accurate tool for forehead, mandibular angles and chin procedures for FFS.

Accumulating evidence support the hypothesis that long noncoding RNAs (lncRNAs) are involved in several physiological and pathological conditions, including cancer. Here, we investigated the potential role of lncRNAs in bladder cancer.
We first looked at available datasets retrieved from the TCGA database and discovered that the lncRNA KTN 1 antisense RNA 1 (KTN1-AS1) was significantly up-regulated in several cancer types including bladder cancer, but was decreased in some other tumors. Therefore, we focused our attention on KTN1-AS1. link3 Using both in vitro and in vivo systems that allowed the modulation of KTN1-AS1 and expression of other relevant proteins, we investigated in-depth the role of KTN1-AS1 in bladder cancer (and the mechanism behind). We further investigated the potential KTN1-AS1-interacting proteins using RNA immunoprecipitation, and explored the KTN1-AS1-related epigenetic landscape (with a particular emphasis on acetylation) using chromatin immunoprecipitation (ChIP) assays.
KTN1-AS1 silencing inhibited the proliferation, invasion, and migration of bladder cancer cells, while KTN1-AS1 overexpression had the obvious opposite effects.
