The activity of tumor-associated TLS was dictated by the relative balance between functional Tfh TIL and functional Tfr TIL. These data provide mechanistic insight into TLS processes orchestrated by functional Th1-oriented Tfh TIL, including TIL-B and CD8+ TIL activation and immunological memory generation. Tfh TIL, regulated by functional Tfr TIL, are an expected key target of PD-1/PD-L1 blockade.Benign prostatic hyperplasia (BPH) is one of the most common chronic diseases in men over the age of 50. Clinical studies have suggested that chronic inflammation is associated with BPH pathoprogression. Berberine (BB) is a natural compound found in Berberis vulgaris, Coptis chinensis and Phellodendron amurense. Although several studies have documented that BB may be effective for inflammation, the effects of the oral administration of BB on BPH are not fully understood. The effects of BB on chronic prostatic inflammation were evaluated in a testosterone-induced BPH animal model. Orally administered BB alleviated the pathological alterations induced by BPH and significantly suppressed the expression of inflammatory markers while enhancing the expression of antioxidant factors. Furthermore, BB regulated the activation of macrophages via NF-κB signaling pathway inhibition in the BPH rat model. The effects and underlying signaling pathway of BB in RWPE-1 cells exposed to macrophage conditioned medium (CM) were also demonstrated in vitro. While CM stimulation induced prostatic cell proliferation and upregulated the expression of inflammatory factors, BB exerted anti-proliferation and anti-inflammatory effects in RWPE-1 cells. These findings propose that BB suppresses androgen-dependent BPH development by targeting NF-κB-mediated pro-inflammatory signaling.Children are known to be better protected from COVID-19 than adults, but their susceptibility patterns and the risk relative to other diseases are insufficiently defined. Here, we found that the COVID-19 mortality rate is U-shaped in childhood it initially decreases, reaching the minimum at the ages 3-10 years, and then increases throughout life. Liproxstatin-1 cell line All-cause mortality and mortality from other diseases, such as pneumonia and influenza, show a similar pattern; however, childhood mortality rates from COVID-19 are considerably lower than from other diseases, with the best relative protection achieved at the youngest ages. Consistent with this, the fraction of COVID-19 deaths among all deaths increases as a function of age throughout childhood and the entire life. We discuss implications of the elevated postnatal COVID-19 risk and lower childhood COVID-19 mortality compared to other diseases.It is well recognized that not all individuals age equivalently, with functional dependence attributable, at least in part, to stress accumulated across the lifespan. Amongst these dependencies are age-related declines in cognitive function, which may be the result of impaired inhibitory processing (e.g., sensory gating). Herein, we examined the unique roles of life and biological stress on somatosensory gating dynamics in 74 adults (22-72 years old). Participants completed a sensory gating paired-pulse electrical stimulation paradigm of the right median nerve during magnetoencephalography (MEG) and data were subjected to advanced oscillatory and time-domain analysis methods. We observed separable mechanisms by which increasing levels of life and biological stress predicted higher oscillatory gating ratios, indicative of age-related impairments in inhibitory function. Specifically, elevations in life stress significantly modulated the neural response to the first stimulation in the pair, while elevations in biological stress significantly modulated the neural response to the second stimulation in the pair. In contrast, neither elevations in life nor biological stress significantly predicted the gating of time-domain neural activity in the somatosensory cortex. Finally, our study is the first to link stress-induced decline in sensory gating to cognitive dysfunction, suggesting that gating paradigms may hold promise for detecting discrepant functional trajectories in age-related pathologies in the future.
Immunotherapy with checkpoint inhibitors is currently considered a cornerstone of metastatic renal clear cell cancer (mRCC) therapy. Despite the general improvement in the survival of patients with mRCC, there are some clinical situations that have not been specifically evaluated in clinical trials, such as the use of everolimus before nivolumab.
We performed a retrospective analysis evaluating the efficacy of nivolumab in the real-world setting, including a subset of patients with previous mTOR inhibitor therapy.
From a total of 56 patients, 25 were pre-treated with everolimus before receiving nivolumab. The overall progression-free survival (PFS), overall survival (OS), and objective response rate were 10.3, 21.3 months, and 34%, respectively. There were no statistically significant differences in patients who were or were not pre-treated with everolimus.
mRCC patients should be treated with checkpoint inhibitors and prior use of mTOR inhibitors should not be a definitive exclusion criterium.

Pancreatic cancer represents the most lethal abdominal malignancy, the only chance for achieving an improvement in terms of survival being represented by radical surgery. Although it has been considered that venous invasion represents a contraindication for resection, recently it has been demonstrated that in regards to overall survival after radical resection, it is similar to the one reported after standard pancreatoduodenectomy.
A 53-year-old patient with no significant medical past was diagnosed with a borderline resectable pancreatic adenocarcinoma invading the superior mesenteric vein. The patient was submitted to pancreatoduodenectomy en bloc with superior mesenteric vein resection; the two jejunal veins were further anastomosed to the remnant portal vein. The postoperative outcome was favorable; the patient was discharged in the 10
postoperative day.
Although technically more demanding, pancreatoduodenectomy en bloc with superior mesenteric vein resection and jejunal portal anastomosis is feasible and might offer a chance for long-term survival in borderline pancreatic head carcinoma invading the superior mesenteric vein.

We report two cases in which severe skin disorders developed during sorafenib treatment in patients with renal cell carcinoma (RCC) who had previously received nivolumab.
Case 1 A 50-year-old man with RCC received nivolumab as the fifth-line therapy followed by sorafenib as the sixth-line therapy. link2 On day 15 of sorafenib administration, the patient was hospitalized with systemic erythema multiforme, acne-like skin rash, and hand-foot syndrome. Case 2 A 40-year-old man with RCC received nivolumab as the second-line therapy followed by sorafenib as the fifth-line treatment. On day 12 of sorafenib administration, the patient was hospitalized with an acne-like skin rash and hand-foot syndrome. The skin disorders in the two cases improved within 2-3 weeks after sorafenib discontinuation and the start of treatment with topical and oral steroids.
When using sorafenib in patients previously treated with nivolumab, close attention should be paid to the onset of serious skin disorders.

The liver is the digestive organ where metastatic adenocarcinoma of unknown primary site is most often observed.
A 74-year-old man was diagnosed with a growing gallbladder tumor and multiple liver tumors limited to the left lateral sector. Liver tumors were suggested to be primary or secondary adenocarcinoma with no relation to the gallbladder tumor. Also for diagnostic purposes, laparoscopic full-thickness resection of the gallbladder, laparoscopic lateral sectionectomy and lymph node sampling were performed. The final histopathological diagnosis was hyperplastic polyp of the gallbladder and metastatic poorly differentiated adenocarcinoma of the liver. Liver tumors were suspected to originate from the stomach, duodenum, or small intestine; however, the primary sites could not be identified. link3 The patient has been closely followed up without any chemotherapy 3 months after surgery.
Laparoscopic surgery can be strongly recommended for patients with multiple liver tumors of unknown origin concomitant with a gallbladder tumor.

Hematoma is the most frequent complication after Vacuum-Assisted Breast Biopsy (VABB) in 13% of cases. A direct communication channel with patients eases the diagnosis of VABB complications and ensures treatment at an early stage, as outpatients, in most cases. In 2020, due to the COVID-19 pandemic, we observed a reduction of self-reported postoperative complication leading to delay in the identification of harmful complications, therefore leading to need for more invasive treatment.
A 50-year-old patient was admitted to the Emergency Department for dry cough, fever, chest discomfort, dyspnea, and slight confusion four days after VABB. Due to the reported symptoms, the patient was sent to our COVID-19 Emergency Department. The COVID-19 swab was negative. Ultrasound revealed a large hematoma at the biopsy site, with active bleeding. Open evacuation with accurate hemostasis was planned with rapid and complete resolution of the clinical symptoms. After surgery, the patient reported that she intentionally avoided admittance in the hospital due to the risk of COVID-19 infection. The patient was discharged in the first postoperative day and maintained in quarantine for 14 days.
In the COVID-19 era due to the risk of hospital cross-infections, reduction of patient-doctor communication could lead to misdiagnosis, delay in recognition of procedural complications thus leading to requirement for invasive treatment, hospitalization, while also further multiplying the risk of COVID-19 infection.

We present the case of a 19-year-old male patient diagnosed concomitantly with extensive thromboses (including two intra-cardiac masses and Budd-Chiari syndrome), as well as acute myeloid leukemia. This necessitated prompt deployment of a monitoring and treatment strategy which included twice-daily blood count assessment, multiple platelet transfusions and anti-coagulation therapy with dose-adjustment per blood count during both induction and consolidation chemotherapy. Multiple factors are believed to contribute to the development of thrombosis in acute leukemia such as diffuse intravascular coagulation, cytokine release and chemotherapy.
Our patient presented early on in the COVID-19 pandemic, delaying his seeking out medical treatment and we suspect this to have contributed to his 'catastrophic' thrombotic presentation. Well-structured guidelines to help clinicians manage these patients are lacking, and most data are from retrospective analyses or case reports. Our patient continued full-dose anticoagulant therapy until successfully undergoing allogeneic stem cell transplant.
