Occurrence and health risk assessment of PFAS and possible precursors: a case study in a drinking water treatment plant and bottled water (south Catalonia, Spain).

The presence of PFAS in drinking water may pose a serious threat to human health. This study aims to determine the levels of these compounds and their precursors in water samples from a drinking water treatment plant (DWTP) located in l'Ampolla (Spain) and to assess their fate. Additionally, ten Spanish bottled waters were analyzed to compare the occurrence of PFAS in the mentioned matrices and in drinking water.

A phase II study of neoadjuvant liposomal irinotecan with 5-FU and oxaliplatin (NALIRIFOX) in pancreatic adenocarcinoma.

For patients with localized pancreatic cancer with minimal vascular involvement, optimal survivability requires a multidisciplinary approach of surgical resection and systemic chemotherapy. FOLFIRINOX is a combination chemotherapy regimen that offers promising results in the perioperative and metastatic settings; however, it can cause significant adverse effects. Such toxicity can negatively impact some patients, resulting in chemotherapy discontinuation or surgical unsuitability.

Effects of Clinical and Tumor Characteristics on Survival in Patients with Hepatocellular Carcinoma with Bone Metastasis.

Background: Advanced hepatocellular carcinoma (HCC) generally has a dismal prognosis. Bone metastases from HCC are infrequent, with a poorer prognosis. However, the survival influencing factors are not yet well understood.

National adoption of neoadjuvant chemotherapy: paradigm shift in the treatment of pancreatic cancer.

Background: The historical standard of care in treating operable pancreatic cancer via upfront surgery has been challenged recently using a neoadjuvant approach. The aim of the study is to examine the national practice patterns in the management of pancreatic cancer with an emphasis on the trends of neoadjuvant systemic therapy use.

Methods: This is a cross-sectional time-series study using the National Cancer Database from 2006 to 2019.

Association of candidate genetic variants and circulating levels of ApoE/ApoJ with common neuroimaging features of cerebral amyloid angiopathy.

Introduction: Cerebral amyloid angiopathy (CAA) is characterized by the accumulation of amyloid-β (Aβ) in brain vessels and is a main cause of lobar intracerebral hemorrhage (ICH) in the elderly. CAA is associated with magnetic resonance imaging (MRI) markers of small vessel disease (SVD). Since Aβ is also accumulated in Alzheimer's disease (AD) in the brain parenchyma, we aimed to study if several single nucleotide polymorphisms (SNPs) previously associated with AD were also associated with CAA pathology.

Importance of carbohydrate antigen (CA 19-9) and carcinoembrionic antigen (CEA) in the prognosis of patients with duodenal adenocarcinoma: a retrospective single-institution cohort study.

Background: Duodenal adenocarcinoma (DA) is a rare malignancy without validated tumor markers. In practice, carcinoembryonic antigen (CEA) and carbohydrate antigen (CA 19-9) are often used in the management of DA, though their prognostic value is unknown.

Materials And Methods: A single-institution retrospective review included patients diagnosed with biopsy-confirmed adenocarcinoma of the duodenum between 2006 and 2021.

Associations of Total Body Fat Mass and Skeletal Muscle Index with All-Cause and Cancer-Specific Mortality in Cancer Survivors.

: The importance of body composition on cancer outcomes is of great clinical interest. Measures of body composition that differentiate fat mass from skeletal muscle mass can help redefine our understanding of body composition for cancer survival. We investigated whether the risk of all-cause and cancer-specific mortality differ by levels of total fat mass and sarcopenia status in cancer survivors.

Chemotherapy is associated with improved survival in a national cohort of stage IV pancreatic adenosquamous carcinoma.

Background: Pancreatic adenosquamous carcinoma (PASC) is a rare cancer that often presents with advanced disease and carries a grim prognosis. PASC is defined by the presence of at least 30% malignant squamous cells in the presence of malignant ductal adenocarcinoma. The utility of chemotherapy in the setting of metastatic disease is unknown.

Advanced Hepatocellular Carcinoma in Adults Without Cirrhosis: A Single-Institution Retrospective Review.

Background: Although up to one in five cases of hepatocellular carcinoma (HCC) occurs in patients without cirrhosis, there is scarce literature characterizing non-cirrhotic HCC (NCHCC). Existing NCHCC research is primarily limited to surgical case series and there is a lack of data on unresectable NCHCC.

Aim: The purpose of this retrospective review was to compare the characteristics of unresectable NCHCC and cirrhotic hepatocellular carcinoma (CHCC).

Atezolizumab plus tivozanib for immunologically cold tumor types: the IMMCO-1 trial.

Immune checkpoint inhibitor therapy represents a significant advance in cancer care. The interaction between PD-1 and PD-L1 induces immune tolerance and the inhibition of this interaction is an effective treatment strategy for numerous malignancies. Despite its demonstrated potential, immunotherapy is not clinically effective in immunogenically 'cold' tumors such as pancreatic cancer, prostate cancer and neuroendocrine tumors.

Effectiveness of radiotherapy for local control in T3N0 rectal cancer managed with total mesorectal excision: a meta-analysis.

Introduction: The total mesorectal excision (TME) significantly improved rectal cancer outcomes. Radiotherapy's benefit in T3N0 rectal cancer patients managed with TME has not been clearly demonstrated. A systematic review and meta-analysis were undertaken to determine whether radiotherapy altered the risk of locoregional recurrence (LR) in T3N0 rectal cancer patients managed with a TME.

Association of social determinants of health with late diagnosis and survival of patients with pancreatic cancer.

Background: Pancreatic cancer disparities have been described. However, it is unknown if they contribute to a late diagnosis and survival of patients with metastatic disease. Identifying their role is important as it will open the door for interventions.

Clinical Updates for Colon Cancer Care in 2022.

Colon cancer needs better screening and treatment options. Its incidence in the young population is rising. Recent changes in guidelines recommend beginning screening for colon cancer at the age of 45.

Percutaneous image-guided treatment of aneurysmal bone cysts: is there a superior treatment option?

Background: Aneurysmal bone cysts (ABCs) are often treated with intralesional surgery (curettage) with or without adjuvant treatments. Side effects and conflicting results regarding recurrence rates do not suggest one clearly superior therapy. Percutaneous therapeutic options including sclerotherapy and thermal ablation have gained popularity as potential alternatives.

Evaluating Rates of Recurrent Ischemic Stroke Among Young Adults With Embolic Stroke of Undetermined Source: The Young ESUS Longitudinal Cohort Study.

Importance: Cryptogenic strokes constitute approximately 40% of ischemic strokes in young adults, and most meet criteria for the embolic stroke of undetermined source (ESUS). Two randomized clinical trials, NAVIGATE ESUS and RESPECT ESUS, showed a high rate of stroke recurrence in older adults with ESUS but the prognosis and prognostic factors among younger individuals with ESUS is uncertain.

Objective: To determine rates of and factors associated with recurrent ischemic stroke and death and new-onset atrial fibrillation (AF) among young adults.

Impact of Medicaid Expansion Status and Race on Metastatic Disease at Diagnosis in Patients with Melanoma.

Background: Black patients are diagnosed with melanoma at a later stage, as compared with their white counterparts. It is unknown if Medicaid expansion might ameliorate this disparity.

Methods: Using data from the 2016 National Cancer Database, we conducted a retrospective cohort study.

The impact of neoadjuvant concurrent chemoradiation on exosomal markers (CD63 and CD9) expression and their prognostic significance in patients with rectal adenocarcinoma.

Introduction: Exosomes have pivotal roles in cancer development. The impact of neoadjuvant concurrent chemoradiation (NCCR) on exosomal markers (CD63 and CD9) expression and their prognostic significance in patients with rectal adenocarcinoma are yet to be explored.

Materials And Methods: Between 2015 and 2018, 33 patients had rectal adenocarcinoma treated with NCCR and had pre-NCCR biopsy and post-NCCR resected rectum.

Presence, behaviour and removal of selected organic micropollutants through drinking water treatment.

This paper investigates the occurrence and removal of 60 organic micropollutants (OMPs) including pharmaceuticals, personal care products, pesticides and per- and polyfluoroalkyl substances in a drinking water treatment plant (DWTP) treating raw water from the Ebro River (NE Spain).

Thirty-one of the sixty OMPs studied were detected in source water with individual median concentrations below 10 ng L for all the compounds except for caffeine (64.

In-hospital opioid usage following posterior spinal fusion for adolescent idiopathic scoliosis: Does methadone offer an advantage when used with an ERAS pathway?

Purpose: Intraoperative methadone has been shown to decrease opioid medication requirement following posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS). No study to date has investigated the effect of methadone on opioid medication requirement when used in conjunction with an enhanced recovery after surgery (ERAS) protocol following PSF.

Methods: A retrospective cohort study was performed at a single, tertiary care pediatric hospital.

Short term outcomes of an enhanced recovery after surgery (ERAS) pathway versus a traditional discharge pathway after posterior spinal fusion for adolescent idiopathic scoliosis.

Purpose: Enhanced Recovery after Surgery (ERAS) pathways have been shown to decrease length of stay (LOS) after posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS). The aim of this study was to compare immediate post-operative outcomes following an ERAS pathway with a traditional pathway for AIS.

Methods: A prospective dual-center study of patients treated using an ERAS pathway (203 patients) or a traditional discharge (TD) pathway (73 patients) was performed with focus on pain at discharge, quality of life at one month, and return to school/work.

A liquid chromatography tandem mass spectrometry method for determining 18 per- and polyfluoroalkyl substances in source and treated drinking water.

Per- and polyfluoroalkyl substances (PFASs) have been determined in waters intended for human consumption, causing concern due to their potential toxic effects in humans and the environment. Drinking water is acknowledged to be one of the major routes of exposure to PFASs, which has led to the implementation of regulatory guidelines for PFASs in drinking water. In this study a fast, simple, sensitive and cost-effective method is developed for the determination of 18 PFASs in river and drinking water.

Liquid chromatography tandem mass spectrometry determination of 34 priority and emerging pollutants in water from the influent and effluent of a drinking water treatment plant.

This study evaluates the applicability of a method based on the direct injection of a large volume of water samples to identify and quantify 34 priority and emerging substances, most of them discussed in Directive 2013/39/EU on priority substances in the field of water policy, and Decision 2018/840/EU (Watch List). The method directly injects 500 µL of filtered water sample and so does not use a pre-concentration step. The method was satisfactorily validated for influent and effluent water from a drinking water treatment plant, at three concentrations (1, 10 and 100 ng L) with precision and accuracies in the range 1-17% and 71-122% respectively.
