Activity and safety of avelumab in high-grade neuroendocrine tumors and poorly differentiated neuroendocrine carcinomas progressive after chemotherapy (AveNEC trial).

Background: Neuroendocrine neoplasias grade 3 (NEN G3) are rare tumors with poor prognosis and no established second-line therapy. The role of immune checkpoint blockade in these aggressive tumors remains unclear.

Methods: The phase II AVENEC study evaluated the effect of avelumab (AVE, 10 mg/kg IV Q2W) in 60 patients with well-differentiated high-grade neuroendocrine tumors (NET G3, N=22) or poorly differentiated neuroendocrine carcinomas (NEC, N=38) progressing after ≥ one prior chemotherapy (excluding Merkel cell and small-cell lung cancer).

Stuck in the Sump: A Rare Complication of Biliary Surgery.

Sump syndrome is a rare complication of biliary surgery that is now rarely seen in the era of Endoscopic Retrograde Cholangiopancreatography (ERCP). It occurs when the distal common bile duct becomes obstructed between an anastomosis from a choledochoduodenostomy (CDD) and the ampulla of Vater, forming a sump that accumulates debris. Sump syndrome should be considered as a diagnosis in patients who present with cholangitis or pancreatitis and any history of biliary diversion, regardless of the time of presentation.

Multicomponent body composition of university club sport athletes.

Background: The body composition of National Collegiate Athletic Association (NCAA) athletes is well documented but no such data exist for university club sports athletes. Additionally, the majority of norms for NCAA athletes were created from individual methods requiring assumptions.

Objective: This study used a four-component (4C) model to measure the body composition of university club sports athletes.

Microbial diversity and biogeochemical interactions in the seismically active and CO- rich Eger Rift ecosystem.

The Eger Rift subsurface is characterized by frequent seismic activity and consistently high CO concentrations, making it a unique deep biosphere ecosystem and a suitable site to study the interactions between volcanism, tectonics, and microbiological activity. Pulses of geogenic H during earthquakes may provide substrates for methanogenic and chemolithoautotrophic processes, but very little is currently known about the role of subsurface microorganisms and their cellular processes in this type of environment. To assess the impact of geologic activity on microbial life, we analyzed the geological, geochemical, and microbiological composition of rock and sediment samples from a 238 m deep drill core, running across six lithostratigraphic zones.

Minimally invasive screw fixation of the anterior pelvic ring and the distal ilium : Tips and tricks to be successful.

Objective: Minimally invasive percutaneous techniques are used to stabilize fractures of the anterior pelvic ring. Stabilization of the fracture facilitates early mobilization and rehabilitation, while percutaneous techniques reduce complications such as infection and bleeding.

Indications: Indicated for patients with non- or minimally displaced fractures of the anterior pelvic ring, or if fracture displacement can be reduced using minimally invasive techniques.

Melioidosis in goats at a single Australian farm was caused by multiple diverse lineages of Burkholderia pseudomallei present in soil.

Background: Burkholderia pseudomallei, causative agent of melioidosis, is a One Health concern as it is acquired directly from soil and water and causes disease in humans and agricultural and wild animals. We examined B. pseudomallei in soil and goats at a single farm in the Northern Territory of Australia where >30 goats acquired melioidosis over nine years.

[Septic pseudarthrosis of the long bones].

Septic pseudarthrosis of long bones presents a diagnostic challenge, both in recognizing the infection as the cause of nonunion and in achieving complete healing of both the infection and the bone. A multidisciplinary approach optimizes the diagnosis, surgical management, and antibiotic treatment. The objectif is to present the approaches for the diagnosis and treatment of this condition.

The role of anthropogenic influences on a tropical lake ecosystem and its surrounding catchment: a case study of Lake Sentani.

Lake Sentani is a tropical lake in Indonesia, consisting of four interconnected sub-basins of different water depths. While previous work has highlighted the impact of catchment composition on biogeochemical processes in Lake Sentani, little is currently known about the microbiological characteristics across this unique ecosystem. With recent population growth in this historically rural area, the anthropogenic impact on Lake Sentani and hence its microbial life is also increasing.

Mass Spectrometry Imaging Distinguishes Biliary Toxicants on the Basis of Cellular Distribution.

Mass spectrometry imaging (MSI) was used to investigate and provide insights into observed biliary pathology found in dogs and rats after administration of two different compounds. Both compounds were associated with peribiliary inflammatory infiltrates and proliferation of the bile duct epithelium. However, MSI revealed very different spatial distribution profiles for the two compounds: Compound A showed significant accumulation within the bile duct epithelium with a much higher concentration than in the parenchymal hepatocytes, while Compound T exhibited only a slight increase in the bile duct epithelium compared to parenchymal hepatocytes.

Metabolic features that select for Bathyarchaeia in modern ferruginous lacustrine subsurface sediments.

Ferruginous conditions prevailed through Earth's early oceans history, yet our understanding of biogeochemical cycles in anoxic iron-rich, sulfate-poor sediments remains elusive in terms of redox processes and organic matter remineralization. Using comprehensive geochemistry, cell counts, and metagenomic data, we investigated the taxonomic and functional distribution of the microbial subsurface biosphere in Lake Towuti, a stratified ferruginous analogue. Below the zone in which pore water becomes depleted in electron acceptors, cell densities exponentially decreased while microbial assemblages shifted from iron- and sulfate-reducing bacterial populations to fermentative anaerobes and methanogens, mostly selecting Bathyarchaeia below the sulfate reduction zone.

Sex-specific NLRP3 activation in neutrophils promotes neutrophil recruitment and NETosis in the murine model of diffuse alveolar hemorrhage.

Objectives: Diffuse alveolar hemorrhage (DAH) is a life-threatening complication of systemic lupus erythematosus and small vessel vasculitis. We previously showed that neutrophil extracellular traps (NETs) were associated with the pathogenesis of pristane-induced DAH and demonstrated that neutrophil NOD-like receptor family pyrin domain containing 3 (NLRP3) inflammasome assembly participated in NET generation under sterile stimulation. We investigated whether NLRP3 inflammasome assembly in neutrophils may drive pulmonary NETosis in a mouse model of pristane-induced DAH.

Metatranscriptomics of microbial biofilm succession on HDPE foil: uncovering plastic-degrading potential in soil communities.

Background: Although plastic pollution is increasing worldwide, very little is known about the microbial processes that take place once plastic debris is incorporated into the soil matrix. In this study, we conducted the first metatranscriptome analysis of polyethylene (PE)-associated biofilm communities in highly polluted landfill soil and compared their gene expression to that of a forest soil community within a 53-day period.

Results: Our findings indicate that the microbial population present in soil contaminated with plastic debris is predisposed to both inhabit and degrade plastic surfaces.

Methods: Evaluation data were 10,674 survey responses from 5,129 unique respondents who identified with the Hip Hop peer crowd between 2016 and 2019. The sample was predominantly non-Hispanic Black and Hispanic youth.

Repetitive transcranial magnetic stimulation in the treatment of opioid use disorder: A narrative review.

It is estimated that over 16 million people are living with opioid use disorder (OUD) worldwide, with 2.1 million people in the United States. Opioid addiction is theorized to be associated with strong dopaminergic response to opioid receptor stimulations that contributes to reward-seeking behaviors and individuals' experiences with opioids.

Spontaneous brain abscess formation: challenge of a shifting pathogen spectrum over the last 21 years - a single center experience.

Background: Spontaneous intracerebral abscess formation is a rare condition presenting with a disabling sequela. The origin of infection can either be primary or secondary to an infection at another location. The site of primary infection - due to the proximity, often the oral cavity, the sinuses, and the orbit - determines the causative pathogens.

Inside the Atacama Desert: uncovering the living microbiome of an extreme environment.

The Atacama Desert in Chile is one of the driest and most inhospitable places on Earth. To analyze the diversity and distribution of microbial communities in such an environment, one of the most important and challenging steps is DNA extraction. Using commercial environmental DNA extraction protocols, a mixture of living, dormant, and dead cells of microorganisms is extracted, but separation of the different DNA pools is almost impossible.

Periodic Bleeding from a Cesarean Section Scar Fistula.

We present the case of a 36-year-old woman who presented to our clinic for a second opinion. After multiple previous surgeries, she presented with an abdominal wound infection, which was initially treated conservatively. In the further course, catamenial bleeding occurred as an unusual symptom, and the suspicion of a fistula formation was postulated.

CBCT-based online adaptive radiotherapy of the prostate bed: first clinical experience and comparison to nonadaptive conventional IGRT.

Purpose: Conventional image-guided radiotherapy (IGRT) of the prostate bed is challenged by the varying anatomy due to dynamic changes of surrounding organs such as the bladder and rectum. This leads to changed dose coverage of target and surrounding tissue. The novel online adaptive radiotherapy (oART) aims to improve target coverage as well as reduce dose exposure to surrounding healthy tissues by daily reoptimization of treatment plans.

Quantitative Analysis of Drugs in a Mimetic Tissue Model Using Nano-DESI on a Triple Quadrupole Mass Spectrometer.

Mass spectrometry is a powerful analytical technique used at every stage of the pharmaceutical research process. A specialized branch of this method, mass spectrometry imaging (MSI), has emerged as an important tool for determining the spatial distribution of drugs in biological samples. Despite the importance of MSI, its quantitative capabilities are still limited due to the complexity of biological samples and the lack of separation prior to analysis.

A Rare Case of Giant Cystic Adenomatoid Tumor of the Uterus With Literature Review.

Adenomatoid tumors are rare benign neoplasms arising from mesothelial cells, commonly found in the female genital system, particularly the uterus and fallopian tubes. The giant cystic variant of adenomatoid tumor is exceptionally rare and can cause massive growth mimicking malignant gynecological conditions. Histology and immunohistochemistry play a crucial role in confirming the diagnosis, with markers such as calretinin, D2-40, CK7, BAP1, ER, and WT1 proving useful.
