Administration of PE-TFG significantly decreased (P<0.05) total cholesterol, LDL, hepatic markers, leptin, TNF-α and improved mRNA expression of adiponectin and PPAR-γ in HFD-fed OVX-rats. Further, micro and macro hepatic steatosis, inflammation, glomerular hypertrophy, degenerated tubules in kidney, increased tunica intima, and media thickness of common carotid artery and the pathological changes were not significant upon PE-TFG administration compared to S.OVX-rats.
PE-TFG protects cellular inflammation and metabolic alternations in HFD-fed OVX-rats and thus can be explored further in postmenopausal diseases as a prophylactic agent.

Pelvic lymph node dissection (PLND) is widely performed for staging in men undergoing radical prostatectomy (RP) for prostate cancer. Our goal was to synthesize all available evidence and data to evaluate perioperative complications for two templates of PLND, standard (sPLND) vs extended (ePLND), at the time of RP in patients with prostate cancer.
A meta-analysis was performed on relevant literature about complications during PLND. Pubmed, Scopus, WebofScience, and Cochrane Library were systematically searched through July 2021. Meta-analysis was conducted with both fixed-effects and random-effects models to estimate risk ratios (RRs) between treatments. A subgroup analysis was also conducted based on surgery type - open vs robotic.
13 (1 randomized clinical trial and 12 observational studies) studies published between 1997 and 2019 with a total of 7,036 patients were analyzed. Pooled data showed complications in a random-effects model was lower in the sPLND group than the ePLND group (RR, 0.62; 95% CI 0.40-0.97). In a subgroup analysis, neither the open surgery subgroup nor the robotic surgery subgroup showed significant differences in complication rate between sPLND and ePLND.
ePLND is associated with a significantly greater risk of perioperative complication compared to sPLND, but not when comparing these templates performed via a robotic approach. Additional studies comparing the complication rates of sPLND and ePLND when utilizing a robotic approach should be conducted.

With the presence of the mature prostate gland there persists a risk for malignant transformation in this population. The recognition by the medical community and society at large that transgender women are at risk of developing prostate cancer has recently been supported by investigative efforts. The slowly emerging clinical evidence suggests that the disease is likely to be more aggressive than in cisgender men, with 6 of 9 published cases discussing metastasis reporting metastatic disease on presentation. Currently the overall prevalence appears low, pointing to evolving awareness, educational status, socioeconomic status, and late presentation. This commentary focuses on exploring the factors contributing to the incidence of prostate cancer and the biochemical and endocrine mechanisms that lead to aggressive prostate tumor development in transgender women.Hypospadias, one of the commonest congenital anomalies in boys, can have a spectrum of clinical presentation based on the location of the meatus and the presence of chordee. The surgical repair of hypospadias involves great precision, especially in proximal varieties and redo/complex cases of hypospadias. Hypospadiologists have put in tremendous efforts to improve the outcomes of these children. The utilization of adjuvant biomaterials is one such effort that has gained significant attention over the recent years. Biomaterials are used to cover the urethral suture line in instances where the ideal covering agents (dartos fascia and tunica vaginalis) are unavailable. We reviewed the mechanism of action, current stance, and advantages/disadvantages of three commonly used adjuvant agents, i.e. autologous platelet concentrates, tissue glues, and acellular dermal matrixes. Although individual studies have highlighted the therapeutic benefits of these adjuvants, the available literature has a limited level of evidence. Moreover, it is believed that the application procedure of these covering agents needs to be scrutinized in future studies. In addition, it is suggested that the application of any covering agent right up to the meatus is non-anatomical and redundant. Well-designed randomized controlled trials with a uniform application procedure and comparing different covering agents need to be conducted in the future before any definite conclusion is drawn.Renal cell carcinoma (RCC) with inferior vena cava (IVC) and right atrium (RA) tumor thrombus (TT) is a rare occurrence and its resection is surgical challenge. Management becomes even more difficult when the TT causes hepatic vein obstruction and leads to Budd-Chiari syndrome. We report a case of 68-year-old male with right RCC with IVC and RA TT with associated Budd-Chiari syndrome. Surgical management was performed without cardiopulmonary bypass (CPB) and re-sternotomy due to the patient's previous history of coronary artery bypass grafting (CABG) for 3 vessel coronary artery disease. Through a transabdominal approach, the diaphragm was dissected off the IVC and the RA was gently pulled into the abdomen and clamped under transesophageal echocardiogram (TEE) control. As use of CPB in these surgeries is associated with increased morbidity and mortality, this organ transplant-based approach is encouraged for patients requiring resection of RCC with supradiaphragmatic TT.The impact of developmental exposure to environmental chemicals on lower urinary tract function is not well understood, despite the fact that these chemicals could contribute to etiologically complex lower urinary tract symptoms (LUTS). Polychlorinated biphenyls (PCBs) are environmental toxicants known to be detrimental to the central nervous system, but their impact on voiding function in mouse models is not known. Therefore, we test whether developmental exposure to PCBs is capable of altering voiding physiology in young adult mice. C57Bl/6J female mice received a daily oral dose of the MARBLES PCB mixture for two weeks prior to mating and through gestation and lactation. The mixture mimics the profile of PCBs found in a contemporary population of pregnant women. Voiding function was then tested in young adult offspring using void spot assay, uroflowmetry and anesthetized cystometry. PCB effects were sex and dose dependent. Overall, PCBs led to increases in small size urine spots in both sexes with males producing more drop-like voids and greater peak pressure during a voiding cycle while females displayed decreases in void duration and intervoid interval. Together, these results indicate that developmental exposure to PCBs are capable of altering voiding physiology in young adult mice. Further work to identify the underlying mechanisms driving these changes may help develop more effective preventative or therapeutic strategies for LUTS.Vertebral lesions in patients with Renal Cell Carcinoma (RCC) are usually assumed to be metastatic. Synchronous malignancies are a rare occurrence. Association between Multiple myeloma (MM) and RCC has been described in the past. Common risk factors and similar cytokine growth requirements could be the linking factors. Here, we describe a patient who had RCC and on evaluation of the vertebral lesion, was found to have Multiple myeloma. Selleck AU-15330 We would like to highlight the fact that not all vertebral lesions in RCC are metastatic. Appropriate evaluation for the vertebral lesion would provide holistic treatment in such patients and improve outcomes.
The role of androgens and other sex steroids is known to influence the prognosis and progression of prostate cancer through different disease states. While androgens are generally regarded as immunosuppressive and estrogens as inflammatory, the specific influence of sex steroids on the immune microenvironment of prostate tumors remains incompletely understood.
In this study, we evaluate the link between sex steroids and prostate cancer immune cells, particularly macrophages. Using
and
models, as well as
culture of patient prostate tissue, we evaluated the influence of androgen, estrogen, and progesterone on immune cells of the prostate microenvironment.
, we observed sex steroids induced indirect changes on prostate cancer cell proliferation via THP-1 derived macrophages, but no clear changes were induced using human monocyte derived macrophages. Comparing immunohistochemistry for immunosuppressive macrophage marker CD163 with concomitant circulating sex steroids from the same patients, we observed a correlation with higher dehydroepiandrosterone (DHEA)-sulfate and estrone-sulfate levels associated with higher prostate CD163 expression. Similar relationships between DHEA and CD163 levels were observed in
cultured prostate biopsies. Finally, in a murine prostate cancer model of long-term sex steroids we observed significant differences in tumor growth in mice implanted with estrogen and DHEA diffusion tubes.
Our results highlight the complex influence of sex steroids on the immune cell composition of prostate tumors. Understanding this biology may help to further personalized therapy and improve patient outcomes.

Assessment of pragmatic language difficulties is limited with conventional tests but can be performed with informant reports. We evaluated the performance of a parent-completed language scale in differentiating autism from typical development (TD) and another neurodevelopmental disorder. Specifically, we aimed to gauge the respective values of structural and pragmatic language scores for diagnostic discrimination and for predicting severity of social impairment in autistic children.
174 children aged 7 to 17 (101 with autism, 45 with ADHD, 28 with TD) were evaluated with the ADOS-2 and an abbreviated version of the WISC. Parents completed the Children's Communication Checklist, 2nd Edition (CCC-2) and the Social Responsiveness Scale. CCC-2 mean differences across diagnostic groups were tested with analysis of variance and covariance. Multiple linear regression was used to compare the structural and pragmatic CCC-2 scores in predicting autism symptom severity.
Both structural and pragmatic language scores discriminated between the three diagnostic groups, with stronger effects for the pragmatic scores. Pragmatic scores remained robust predictors of ADHD and ASD diagnoses even after accounting for cognitive and structural linguistic differences. Among autistic children, social impairment severity was associated with pragmatic, but not structural, language profiles.
In order to characterize pragmatic language, easy to administer parent questionnaires such as the CCC-2 may support clinicians who are considering an autism diagnosis and needing to evaluate and monitor social communication.
