009 and p=.001, respectively) compared with the 30% O2 group after adjustment for Hb concentration. The SPM RvD2 and RvE2 were increased with 50% and 80% O2 (RvD2, p=.014 and p=.002, respectively; RvE2, p=.032 with 50% O2) compared with the 30% O2 group, in analyses that corrected for Hb concentration. We have shown for the first time that higher O2 levels may be beneficial in reducing oxidative stress and increasing resolution of inflammation during surgery that involves reperfusion after application of a tourniquet.Primary adenocarcinoma of the anorectum, compared with squamous cell carcinoma, is a rarer and more aggressive malignant neoplasm. Infection with human papillomavirus (HPV) has been identified as a causal agent in a variety of tumors, including those of the cervix, head and neck, and anogenital region, especially squamous cell carcinoma. However, the relationship between HPV and anorectal adenocarcinoma has not been well studied. In this article, we report an HPV-related anorectal adenocarcinoma arising in a tubulovillous adenoma in a 76 years old female who presented initially with lower gastrointestinal bleeding. The carcinoma cells were positive for cytokeratin 7 and p16 by immunohistochemistry. High-risk HPV RNA in situ hybridization was positive. A follow-up examination of the anal area showed perianal plaques. Histologically, the excision of the perianal lesion showed intraepithelial infiltration by sheets and clusters of large atypical neoplastic cells. The neoplastic cells showed the same immunoprofile compared with the anorectal adenocarcinoma with p16 and high-risk HPV positivity. The findings are consistent with extramammary perianal Paget's disease secondary to anorectal adenocarcinoma. HPV-related adenocarcinoma in the anorectum is a newly recognized entity and was previously considered clinically indolent. Our case uniquely exhibits adenoma-carcinoma-perianal Paget's disease sequence, which has not been reported before. Our findings suggest that evaluation of the patient's lower genital tract for any HPV-associated lesions and long-term follow-up are required to monitor the disease progression in this type of malignancy.Introduction Immune checkpoint inhibitors (ICI) have shown great promise in a wide spectrum of malignancies. However, responses are not always durable, and this mode of treatment is only effective in a subset of patients. As such, there exists an unmet need for novel approaches to bolster ICI efficacy.Areas covered We review the role of the Tyro3, Axl, and Mer (TAM) receptor tyrosine kinases in promoting tumor-induced immune suppression and discuss the benefits that may be derived from combining ICI with TAM kinase-targeted tyrosine kinase inhibitors. We searched the MEDLINE Public Library of Medicine (PubMed) and EMBASE databases and referred to ClinicalTrials.gov for relevant ongoing studies.Expert opinion Targeting of TAM kinases may improve the efficacy of immune checkpoint blockade. TGF-beta inhibitor However, it remains to be determined whether this effect will be better achieved by the selective targeting of each TAM receptor, depending on the context, or by multi-receptor TAM inhibitors. Triple inhibition of all TAM receptors is more likely to be associated with an increased risk for adverse events. Clinical trial designs should use high-resolution clinical endpoints and proper control arms to determine the synergistic effects of combining TAM inhibition with immune checkpoint blockade.The peel of pomegranate fruit is a rich source of polyphenolic compounds with powerful antioxidant properties. We evaluated the therapeutic potential of pomegranate peel (PP) in the prevention of early pregnancy loss in a mouse model of embryonic mortality and abortion (female CBA/J x male DBA/2). CBA/J mice were divided into 3 groups mice in control group (CONT group) were fed a standard diet, whereas mice in groups 2 and 3 were fed a standard diet supplemented with 1% PP (PP1% group) and 5% PP (PP5% group), respectively. All the mice were fed their diets for 10 days before mating and continued with the same diets for a further 14 days after mating. At day 14 of pregnancy the female mice were sacrificed and the placentas and maternal livers were harvested for measurement of the content of thiols and thiobarbituric acid reactive substances (TBARS), as biomarkers of oxidative stress, and the enzymatic activities of total superoxide dismutase (TSOD), copper/zinc SOD (SOD1), manganese SOD (SOD2), selenium glutathione peroxidase (GPX) and glutathione reductase (GR). Diet supplemented with 5% PP improved embryonic survival and reduced embryonic mortality from 28.2% (CONT) to 8.5% (PP5%). This was accompanied by increased activities of placental TSOD, SOD1 and SOD2, and thiol content. Diet supplemented with 5% PP also reduced placental oxidative stress as demonstrated by a decrease of placental TBARS content. This study highlights the potential of interventions with PP-supplemented diet before and during early pregnancy, in order to ameliorate embryonic survival and prevent early pregnancy loss.

To assess the variables associated with success of office hysteroscopy (OH) in pre-menopausal and post-menopausal women and to develop a clinical model for predicting the outcome of OH.

This is a retrospective cohort study of consecutive patients (

 = 3181) referred for an OH to a tertiary care university hospital between January 2018 and March 2020. Multivariate logistic regression analysis was used to investigate the variables for predicting the success of OH in all patients and in pre-menopausal and in post-menopausal patients separately. The logistic regression analysis of each variable was applied to develop a predictive model.

The overall success rate of the procedure was 92.2%; 95.4% in pre-menopausal women and 87.6% in post-menopausal women. In the general population, independent predictors of procedure success were previous vaginally delivery and hysteroscopy, while previous cervical or uterine surgery were associated with incomplete OH. In the pre-menopausal group, the independent predictors of failure were treatment with GnRH, estroprogestins and infertility. In 89% of cases, our developed model was able to predict whether an OH would be successful in a particular patient. ROC analysis showed an area under the curve of 0.8746 (95% CI 0.85354-0.89557).

The present study demonstrates the development of a simple and reliable clinical model for the identification of both pre-menopausal and menopausal patients with a high chance of OH success.
