Per- and polyfluoroalkyl substances (PFAS) are widespread environmental contaminants linked to adverse outcomes, including for female reproductive biology and related cancers. We recently reported, for the first time, that PFAS induce platinum resistance in ovarian cancer, potentially through altered mitochondrial function. Platinum resistance is a major barrier in the management of ovarian cancer, necessitating complementary therapeutic approaches. Photodynamic therapy (PDT) is a light-based treatment modality that reverses platinum resistance and synergizes with platinum-based chemotherapy. The present study is the first to demonstrate the ability of photodynamic priming (PDP), a low-dose, sub-cytotoxic variant of PDT, to overcome PFAS-induced platinum resistance. Comparative studies of PDP efficacy using either benzoporphyrin derivative (BPD) or 5-aminolevulinic acid-induced protoporphyrin IX (PpIX) were conducted in two human ovarian cancer cell lines (NIHOVCAR-3 and Caov-3). BPD and PpIX are clinically approved photosensitizers that preferentially localize to, or are partly synthesized in, mitochondria. PDP overcomes carboplatin resistance in PFAS-exposed ovarian cancer cells, demonstrating the feasibility of this approach to target the deleterious effects of environmental contaminants. Decreased survival fraction in PDP + carboplatin treated cells was accompanied by decreased mitochondrial membrane potential, suggesting that PDP modulates the mitochondrial membrane, reducing membrane potential and re-sensitizing ovarian cancer cells to carboplatin.
Underwater endoscopic mucosal resection (uEMR) without submucosal injection for sessile colorectal polyps was introduced as a newer replacement for conventional EMR (cEMR). However, the optimal resection strategy remains a topic of debate. Hence, this meta-analysis was conducted to compare the efficacy and safety of uEMR and cEMR in patients with sessile colorectal polyps.

A comprehensive search of literature from 2000 till January 2022 from MEDLINE, CENTRAL and EMBASE for randomized controlled trials (RCTs) comparing cEMR vs. uEMR for colorectal polyps. The evaluated outcomes included En-bloc resection, R0 resection, procedural time, overall bleeding, and recurrence. Pooled risk ratios (RR) with 95% confidence interval were calculated using a random effect model.

Six studies were included out of which four were full-text articles and two were conference abstracts. En-bloc resection (RR 1.26, 95% CI 1.00 - 1.60), R0 resection (RR 1.10, 95% CI 0.96 - 1.26), overall bleeding (RR 0.85, 95% CI 0.54 - 1.34) and recurrence rate (RR 0.75, 95% CI 0.45 - 1.27) were comparable between uEMR and cEMR. However, uEMR was associated with a lower procedural time (Mean difference -1.55 minutes, 95% CI -2.71 to -0.39). On subgroup analysis, uEMR led to a higher rate of en-bloc resection (RR 1.41, 95% CI 1.07 - 1.86) and R0 resection (RR 1.19, 95% CI 1.01 - 1.41) for polyps with size ≥ 10 mm.

Both uEMR and cEMR have comparable safety and efficacy. For polyps larger than 10 mm, uEMR may have an advantage over cEMR and should be the topic for future studies.

Varicella zoster virus encephalitis is a potentially serious complication not previously described with its use, highlighting the importance of vaccination, as well as early diagnosis and treatment of infections in this type of patients.BackgroundSalmonellosis remains the second most common zoonosis in the European Union despite a long-term decreasing trend. However, this trend has been reported to have stagnated in recent years, particularly for Salmonella enterica serotype Enteritidis (SE).AimTo describe temporal changes in the incidence of SE human infections, and in its associated factors between 2006 and 2019. In addition, we aim to determine which factors influenced the stagnated trend seen in recent years.MethodsData on culture-confirmed SE human infections from national surveillance registries in the Netherlands and Belgium between 2006 and 2019 were analysed using multivariable negative-binomial regression models with restricted cubic splines.ResultsSE incidence was significantly higher in summer and autumn than winter, in persons aged 0-4 years and 5-14 years than in persons ≥ 60 years, and increased with increasing proportions of travel-related and resistant SE infections. SE incidence decreased significantly in both countries until 2015, followed by an increasing trend, which was particularly pronounced in the Netherlands. learn more Potential SE outbreaks in both countries and invasive infections in the Netherlands also increased after 2015.ConclusionThe increase in potential outbreaks and invasive infections since 2015 may partially explain the observed reversal of the decreasing trend. While these results provide insights into the possible causes of this trend reversal, attention should also be given to factors known to influence SE epidemiology at primary (animal) production and pathogen genomic levels.Influenza virus circulation virtually ceased in Canada during the COVID-19 pandemic, re-emerging with the relaxation of restrictions in spring 2022. Using a test-negative design, the Canadian Sentinel Practitioner Surveillance Network reports 2021/22 vaccine effectiveness of 36% (95% CI -38 to 71) against late-season illness due to influenza A(H3N2) clade 3C.2a1b.2a.2 viruses, considered antigenically distinct from the 3C.2a1b.2a.1 vaccine strain. Findings reinforce the World Health Organization's decision to update the 2022/23 northern hemisphere vaccine to a more representative A(H3N2) clade 3C.2a1b.2a.2 strain.We report the endoscopic finding of a double papilla of Vater in a patient presenting choledocholithiasis who underwent endoscopic retrograde cholangiopancreatography (ERCP). The images showed the presence of two perfectly delimited papillary orifices, 1cm apart from each other. After cannulation of each orifice, we observed the Wirsung and the common bile duct (CBD) as completely independent ducts. Given the diagnostic challenge posed by this entity and the importance of differentiating it from a bilioenteric fistula, we believe it is worth knowing about it in order to manage it properly and to minimize secondary risks during the exploration.
The cut-off values for the skin prick test diameters and cow's milk-specific IgE measurements are used to predict the result of the oral food challenge test for the diagnosis of cow's milk allergy. This study aimed to determine the diagnostic values of skin prick test and cow's milk-specific IgE according to age groups and compare the diagnostic powers of these 2 methods.

In total, 153 children who had a preliminary diagnosis of cow's milk allergy were evaluated. Group A (n = 90) consisted of cow's milk allergy patients whose diagnosis was confirmed by a positive oral food challenge or a history of anaphylaxis. Group B (n = 63) was composed of patients with a negative oral food challenge. The demographic, clinical, and laboratory findings of 2 groups were compared.

The cut-off points for cow's milk-specific IgE and cow's milk-skin prick test were determined as >2.12 kUA/L and >5 mm, respectively. The area under the curve was 0.844 for cow's milk-skin prick test (sensitivity 73%, specificity 84%) aalues of communities for specific IgE and skin prick test along with a significant clinical history may provide accurate and rapid diagnosis of cow's milk allergy and facilitate patient follow-up.
Fever continues to be the most frequent cause of care in the pediatric population. The uses of invasive and unnecessary tests result in discomfort to the patients. Local epidemiological data could help to refine screening strategies, especially in low resources settings. The present study aims to describe the prevalence of serious bacterial infections in infants with fever without source and to evaluate the usefulness of clinical and laboratory parameters in the identification of serious bacterial infections.

We included all children aged 0-36 months presenting with fever without source between January 2015 and December 2017. Demographic and clinical characteristics, investigations, and management procedures were recorded at the time of inclusion. Potential predictors of serious bacterial infections were compared between patients with and without serious bacterial infections.

In total, 137 patients were included. Serious bacterial infections were diagnosed in 41 patients (29.9%; 95% CI, 22%-38%). The moes.A 62-year-old man with a history of heartburn and regurgitation was referred for the management of a black lesion in the middle esophagus. Our Esophagogastroduodenoscopy (EGD) showed a 13 mm, black protruding lesion located 29cm from the incisor teeth. Endoscopic ultrasonography (EUS) showed a 11.7 mm×7.2 mm hyperechoic mass in the esophageal wall arising in layer 2 and 3. Biopsy of the lesion showed a black and elastic hard appearance. Pathological examination showed chronic inflammatory with coal dust underneath the mucosal epithelium.The development of stimulus-responsive luminescent materials, especially those based on a single compound exhibiting multicolor and high-contrast (Δλem ≥ 100 nm) chromic properties, is a critical challenge. In this work, we synthesized and characterized a zinc(II) complex (1). As expected, 1 displays aggregation-induced emission enhancement (AIEE) in THF/H2O mixtures, and remarkable multicolor switching under external stimuli in the solid state. Complex 1 shows reversible mechanochromic luminescence behavior with a large wavelength shift (Δλem = 100 nm) during the grinding-fuming cycles, due to the phase transformation between the crystalline and amorphous states. More impressively, 1 exhibits obvious acidochromic properties (Δλem = 130 nm) which originate from the adsorption of vapor and a gas-solid reaction on the crystal surface. Furthermore, 1 exhibits electrochemical oxidation behavior accompanied by quenching of yellow-green emission due to the overlap of an emission band and an absorption band. The above-mentioned color changes under ambient light can also be observed by the naked eye during the mechanical, acid-base vapor and electrical stimulation. Based on the high-contrast and multicolor switching, complex 1 was successfully developed into test papers and films in the field of rapid detection of mechanical stimuli and HCl/NH3 vapors.A 74-year-old male presented with melena and fatigue, without fever or abdominal pain. Laboratory examination revealed anemia, leukocytosis, elevated C-reactive protein levels and conjugated hyperbilirubinemia with elevated liver enzymes. Upper endoscopy identified blood in the stomach and duodenum and a 6 mm hole in the anterosuperior surface of the duodenal bulb with spontaneous drainage of a bloody brownish content. The mucosa surrounding the hole was normal and there was a discrete mucosal flap that throbbed with air insufflation. Abdominal computed tomography identified a fistulous tract between the duodenal bulb and the gallbladder with a 2 mm caliber, suggesting a cholecystoduodenal fistula. Diagnosis is often difficult because symptoms are nonspecific and variable but gastrointestinal bleeding is a rare clinical presentation.
